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 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Distribute to the channel passphrase in CMODE_CHANGE notify.
13 Updated specs and implemented it. Affected file silcd/command.c,
14 silcd/packet_send.c and silcd/packet_receive.c.

17 command. If provided all conditions for channel joining
18 except requirement to provide correct passphrase can be
19 overrided by the channel founder. Updated the protocol specs.
20 Affected file silcd/command.c.
22 Added support for founder auth in JOIN command in client
23 library. Fixed the parsing of the JOIN command now to support
24 all options as they should be. The affected file is
25 lib/silcclient/command.c.
27 * Optimized the WHOIS and IDENTIFY commands to send the request
28 to router only if it includes nicknames or other names. If
29 they include only IDs then check the local cache first before
30 routing. Affected file is silcd/command.c.
32 * Added channels topic announcements. Affected file is
33 silcd/packet_receive.c and silcd/server.c.
35 * Fixed the silc_server_send_notify_topic_set to really destine
36 the packet to channel. Affected file silcd/packet_send.c.
38 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
39 library. Affected file lib/silcclient/client_notify.c.
41 * Added UMODE announcements. Affected file silcd/server.c.

51 lib/silccrypt/silcpkcs.c
52 lib/silccore/silccommand.c
53 lib/silccore/silcidcache.c
58 * ROBOdoc documented the lib/silcske/groups.h file and a
59 bit changed the interface for better.
61 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
63 * Update the client entry context in the ID cache after
64 nick change. Affected file lib/silcclient/command.c.
65 Fixes the CUMODE command when regaining founder privileges,
66 and a little WHOIS problem.
68 * Fixed silc_net_gethostbyname to correctly call the
69 inet_ntop. Affected file lib/silcutil/silcnet.c.
71 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
73 * Added IPv6 support checking to the configure.in.pre, added
74 also --enable-ipv6 option to override the check. Affected
75 file configure.in.pre.
77 * The silc_thread_create now calls the start function

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

221 to run server on foreground. A patch by debolaz.
222 Affected files silcd/server.c, silcd/silcd.c.
224 * Fixed MOTD to return the MOTD file server name. Affected
225 file silcd/command.c.
227 * Added INFO command reply handling to the Irssi SILC Client.
228 Affected file irssi/src/silc/core/client_ops.c.
230 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
232 * Fixed the silc_idcache_list_* routines to really support
233 the dynamic list. Fixes a crash. Affected file is
234 lib/silccore/silcidcache.c.
236 * Fixed the LIST command reply to really call LIST command's
237 pending callbacks. Affected file silcd/command_reply.c.
239 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
241 * Update conn->local_entry->nickname after giving NICK
242 command. Affected file lib/silcclient/command.c.
244 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
246 * Added the [pid] option to the silcd configuration file
248 Affected files: serverconfig.[ch] and silcd.c
250 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
252 * Save fingerprint in WHOIS command reply in server.
253 Affected file silcd/command_reply.c.
255 * Fixed NICK commands pending callback registration.
256 Affected file lib/silcclient/command.c.
258 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Use ++server->cmd_ident when sending commands in server,
261 instead of random number. Affected file silcd/command.c.
263 * Fixed GETKEY command reply to call actually GETKEY pending
264 command callbacks. Affected file silcd/command_reply.c.
266 * A bit stricter check for nicknames. Check for same nickname
267 in NICK command also. Affected file silcd/command.c.
269 * Do not call INFO command everytime client ID changes, only
270 during first connecting. Affected file lib/silcclient/client.c.
272 * Set the new nickname only after successful command reply for
273 NICK command is returned by server. Affected file
274 lib/silcclient/command.c.
276 * Remove nicknames from nicklist during server_signoff notify.
277 Should fix /NAMES bit more. The affected file is
278 irssi/src/silc/core/silc-channels.c.
280 * Added `fingerprint' field to the SilcIDListData in the
281 silcd/idlist.h to hold the fingerprint of the client's
284 Send the fingerprint of the client's public key in WHOIS
287 Affected files silcd/command.c, and silcd/idlist.[ch].
289 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
290 create fingerprint from given data.
292 * Show the fingerprint of the client's public key in WHOIS.
293 Affected files irssi/src/module-formats.[ch] and
294 irssi/src/silc/core/client_ops.c.
296 * Format the multiple same nicknames also during JOIN and
297 NICK_CHANGE notifys. Affected file is
298 lib/silcclient/client_notify.c.
300 * Do not print error on screen for invalid private message
301 payload since it can come if someone is sending private
302 messages with wrong key. Affected file
303 lib/silccore/silcprivate.c.
305 * Fixed multiple concurrent /PING crash. Affected file
306 lib/silcclient/command.c.
308 * Changed the wrong ID encoding. All IP addresses must be
309 in MSB first order in encoded format. They were encoded
310 wrong and was in LSB format. Affected files are
311 silcd/serverid.c, lib/silcutil/silcutil.c.
313 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
315 * Call the `connect' client operation through the scheduler
316 in case of error. Affected file lib/silcclient/client.c.
318 * Call the `failure' client operation even if the error
319 occurred locally during a protocol. Affected file is
320 lib/silcclient/protocol.c.
322 * Added support of sending LIST command to router from normal
323 server. This way normal server can get list of all channels
324 in the network too. Fixed the channel list sending in the
325 server too. Affected files are silcd/command.c, and
326 silcd/command_reply.[ch].
328 * Added silc_server_update_channels_by_server and
329 silc_server_remove_channels_by_server. They are used during
330 disconnection of primary router and in backup router protocol.
331 Affected file silcd/server_util.[ch], silcd/server.c and
332 silcd/server_backup.c.
334 * Fixed channel adding to global list in IDENTIFY command
335 reply in server. Affected file silcd/command_reply.c.
337 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
339 * If the incoming packet type is REKEY or REKEY_DONE process
340 that packet always synchronously. Fixes yet another MAC
341 failed error on slow (dialup) connections. Affected file
342 lib/silcclient/client.c and silcd/server.c.
344 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Call check_version SKE callback for initiator too. Affected
347 file lib/silcske/silcske.c.
349 * Implemented fix for security hole found in the SKE that was
350 fixed in the specification few days back; the initiator's
351 public key is now added to the HASH value computation.
352 Added backwards support for the old way of doing it too, for
353 old clients and old servers. Affected file is
354 lib/silcske/silcske.c.
356 * Enabled mutual authentication by default in SKE. If initiator
357 is not providing mutual authentication the responder will
358 force it. This will provide the proof of posession of the
359 private key for responder. The affected files are
360 lib/silcclient/protocol.c and silcd/protocol.c.
362 * Do not cache anymore the server's public key during SKE.
363 We do mutual authentication so the proof of posession of
364 private key is done, and if the server is authenticated in
365 conn auth protocol with public key we must have the public
366 key already. Affected file silcd/protocol.c.
368 * Added new global debug variable: silc_debug_hexdump. If
369 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
370 file lib/silcutil/silclog.[ch].
372 * Fixed compilation warning due to char * -> const char *.
373 Affected files lib/silcutil/silcnet.h, and
374 lib/silccore/silcauth.[ch].
376 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Fixed CMODE command when new channel key was created. If
379 the creation failed the old key was removed. Next time giving
380 same command would crash the server since the old key was
381 freed already. Affected file silcd/command.c.
383 * Fixed the silc_server_announce_get_channels to not crash
384 on reconnect. Affected file silcd/server.c.
386 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Added silc_log_set_debug_string function to set a regex
389 string to match for debug output. Only the function names,
390 or filenames matching the given debug string is actually
391 printed. This way it is possible to filter out those debug
392 strings that user is not interested in.
394 Fixed a bug in silc_string_regexify.
396 Affected files lib/silcutil/silclog.[ch], and
397 lib/silcutil/unix/silcunixutil.c.
399 * Changed the -d options in both server and Irssi SILC client
400 to take the debug string as argument. Affected files
401 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
403 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Added silc_hash_babbleprint to create a Bubble Babble
406 Encoded fingerprint. The encoding is developed by Antti
407 Huima (draft-huima-babble-01.txt), and it creates human
408 readable strings out of binary data. Affected file
409 lib/silccrypt/silchash.[ch].
411 * Print the babble print now in addition of fingerprint as well
412 in Irssi SILC client. Affected files are
413 irssi/src/fe-common/silc/module-formats.[ch],
414 irssi/src/fe-common/silc/core/client_ops.c.
416 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
418 * Fixed a security problem found in SKE. The initiator's
419 public key too is now added to the HASH hash value creation
420 which is signed by the responder to create the SIGN value.
421 This will prevent anyone in the middle to lie to the responder
422 about the initiator's public key. If this is done now, the
423 man in the middle will get caught. Updated the protocol
426 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Better installation directory handling. Configure module
429 paths and other paths automatically to example_silc* files
430 in doc/. A patch by toma.
432 * Fixed compiler warning from MPI library, and from SILC RNG.
435 * Added SILC_SERVER_PID_FILE to define the pid file for server.
436 It can be configured with ./configure. A patch by toma.
438 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Find correct make to use in prepare-clean. A patch by
441 toma. Affected file prepare-clean.
443 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
445 * Added irssi variables use_auto_addr, auto_bind_ip,
446 auto_bind_port and auto_public_ip.
448 * Changed the interface for silc_client_send_key_agreement
449 in lib/silcclient/silcapi.h
453 irssi/src/silc/core/silc-core.c
455 lib/silcclient/silcapi.h
456 irssi/src/silc/core/silc-channels.c
457 lib/silcclient/client_keyagr.c
460 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
462 * Added silc_pkcs_public_key_compare to compare two
463 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
465 * Check that the client who set the founder mode on the
466 channel is the same client that is giving the founder
467 mode to itself. It is done by comparing the saved public
468 key (it is saved even in the authentication is passphrase).
469 Affected file silcd/command.c.
471 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
473 * Do not process packet for disconnected socket connection.
474 Affected file lib/silccore/silcpacket.c.
476 * Process the DISCONNECT packet through scheduler in the
477 client library. Affected file lib/silcclient/client.c.
479 * Fixed the silc_client_packet_parse to not to increase
480 the packet sequence number if the conn->sock and the
481 current socket connection is not same. This can happen
482 for example during key agreement when the conn includes
483 multiple socket connections (listeners). Affected file
484 lib/silcclient/client.c.
486 * The sender of the file transfer request now provides also
487 the pointer (listener) for the key exchange protocol. If
488 the listener cannot be created then it sends empty key
489 agreement and lets the receiver provide the listener.
491 Added `local_ip' and `local_port' arguments to the
492 silc_client_file_send. If they are provided they are used,
493 if not then it will attempt to find local IP address, if
494 not found or bind fails then the remote client will provide
497 Affected files are lib/silcclient/client_ftp.c and
498 lib/silcclient/silcapi.h.
500 * Extended the FILE SEND command to support defining the
501 local IP and port for key exchange listener. They are
502 optional. Affected file irssi/src/silc/core/silc-servers.c.
504 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
506 * Defined to WHOIS command reply the sending of fingerprint
507 of the client's public key (if the proof of posession of the
508 corresponding private key is verified by the server).
509 Updated to the protocol specification.
511 * Added support of receiving the client's public key's
512 fingerprint in command reply in client library. Affected
513 file is lib/silcclient/command_reply.c, and
514 lib/silcclient/idlist.[ch].
516 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
518 * Do not send over 128 chars long nickname to the server
519 in NICK command. Affected file lib/silcclient/command.c.
521 * Do not send over 256 chars long channel names to the server
522 in JOIN command. Affected file lib/silcclient/command.c.
524 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
526 * Assure that silc_server_close_connection cannot be called
527 twice for same socket context. Affected file is
530 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
532 * Send error message to application if opening file for
533 writing during file transfer fails. Affected file is
534 lib/silcclient/client_ftp.c.
536 Remove all file transfer sessions for a client that we're
537 removing from ID cache.
539 Affected file is lib/silcclient/client_ftp.c.
541 * Fixed silc_net_addr2bin to return correct address. Affected
542 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
544 * Fixed file transfer session removing on signoff notify.
545 Affected file irssi/src/silc/core/silc-servers.c.
547 * Added the SilcClientFileError to be returned in the monitor
548 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
549 Affected file lib/silcclient/silcapi.h.
551 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
553 * Fixed a crash in silc_client_ftp_free_sessions and
554 silc_client_ftp_session_free_client. Affected file
555 lib/silcclient/client_ftp.c.
557 * Added `disabled' field in the SilcChannelEntry in the server
558 to indicate if the server entry is disabled. Affected file
559 silcd/idlist.h, silcd/command[_reply].c.
561 * SILC server adds now /var/run/silcd.pid everytime it is
562 started. Affected file silcd/silcd.c.
564 * Added silc_server_packet_send_clients to send a packet to
565 the provided table of client entries. Affected file
566 silcd/packet_send.[ch].
568 * Fixed a crash in client resolving in client_prvmsg.c in
569 client library. Affected file lib/silcclient/client_prvmsg.c.
571 * Do not actually remove the client directly from ID cache
572 during SERVER_SIGNOFF, but invalidate it. This way we
573 preserve the WHOWAS info for the client. Affected file
576 * Fixed SERVER_SIGNOFF notify handling in the server. The
577 server is now able to process incoming SERVER_SIGNOFF notify
578 for a server that it doesn't even know about. It will remove
579 the clients provided in the notify. Affected file
580 silcd/packet_receive.c.
582 * Check for partial packet in data queue after every packet that
583 was found from the queue. Return and wait for more data if
584 there is partial data in queue. Affected file is

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

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

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

707 * Resolve the client info when received private message or
708 channel message for a client which nickname we don't know.
709 Affected files lib/silcclient/client_prvmsg.c and
710 lib/silcclient/client_channel.c.
712 * Do not crash in /KEY if client is not connected. Affected
713 file irssi/src/silc/core/silc-channels.c.
715 * Added SilcClientStatus field to the SilcClientEntry in the
716 lib/silcclient/idlist.h.
718 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
719 is incomplete and is being resolved, it won't be resolved
722 Make sure also that USERS command reply does not resolve
723 twice information. Affected file is
724 lib/silcclient/command_reply.c.
726 Make sure that silc_client_get_clients_by_list does not
727 resolve twice same information.
729 * Check for valid client->id in the silc_server_free_client_data.
730 Affected file silcd/server.c.

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

918 * Assure that if outgoing data buffer is pending do not force
919 send any data. Affected file lib/silcclient/client.c.
921 * Implemented the backup router support when the primary router
922 goes down. The servers and routers can now use the backup
923 router as new primary router without loosing connectivity.
925 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
927 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
928 in the server to indicate disabled entry. All data read
929 from the connection will be ignored and no data is sent
930 for entry that is disabled. Affected files are
931 silcd/idlist.h, silcd/server.c.
933 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Created SFTP client and server test programs in the
936 lib/silcsftp/tests directory.
938 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Implemented memory filesystem (virtual filesystem) for
941 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
944 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Implemented the SFTP (SSH File Transfer Protocol) to the
947 lib/silcsftp. It includes SFTP client and SFTP server
950 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Moved lib/silccore/silcprotocol.[ch] to the
953 lib/silcutil library.
955 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
956 take variable argument list pointer as argument. Affected
957 file lib/silcutil/silcbuffmt.[ch].
959 * Added silc_buffer_set function that is used to set data
960 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
961 Affected file lib/silcutil/silcbuffer.h.
963 * Changed various routines in the core library to use the new
964 silc_buffer_set instead of allocating new buffer only for
967 * Added 64-bit value formatting and unformatting support to the
968 silc_buffer_[un]format routines. Affected file is
969 lib/silcutil/silcbuffmt.[ch].
971 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
972 to includes/bitmove.h.
974 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Fixed channel user mode saving in client library. Affected
977 file lib/silcclient/command[_reply].c.
979 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Defined the file transfer to the SILC Protocol. Added
982 new packet type SILC_PACKET_FTP and defined File Transfer
983 Payload. The mandatory file transfer protocol is SFTP
984 (SSH File Transfer Protocol). Affected file in addition
985 of the internet draft is lib/silccore/silcpacket.h.
987 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
988 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
989 is used as part of backup router protocol when the primary
990 router of the cell is back online and wishes to resume
991 the position as primary router.
993 * Redefined the MAC generation keys in the protocol. The
994 same key is not used anymore in both direction. Both
995 direction will now use different keys for sending and
996 receiving. This fixes a potential security flaw. This
997 change causes incompatibilities in the protocol.
999 * Redefined also the MAC computation from the packet.
1000 An packet sequence number is now added to the MAC
1001 computation. This prevents possible replay attacks against
1002 the protocol. This change too causes incompatibilities
1005 Added `sequence' field to the SilcPacketContext to hold
1006 the current sequence number for the packet.
1008 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * Added `created' field to the SilcIDListData in the file
1011 silcd/idlist.h to indicate the time when the entry was
1014 * Added `created' field to the SilcChannelEntry too. Affected
1015 file silcd/idlist.h.
1017 * Added `creation_time' aguments to all the announcement functions
1018 in the server. If it is provided then only the entries that
1019 was created after the provided time frame are actually
1020 announced. Affected file silcd/server.[ch].
1022 * The protocol says that the Channel ID's IP address must be
1023 based on the router's IP address. Added check for this in
1024 the silc_server_new_channel when processing incoming New Channel
1025 Payload. Affected file silcd/packet_receive.c.
1027 * Print out the correct version with --version in SILC client.
1028 Affected file irssi/src/silc/core/silc-core.c.
1030 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * Fixed WHOWAS command to check for completnes of the client
1033 entry always, not just when the command is coming from client.
1034 Affected file silcd/command.c.
1036 * Added new function silc_server_packet_queue_purge to purge the
1037 outgoing data queue to the network. After the function returns
1038 it is guaranteed that the outgoing packet queue is empty.
1039 Affected file silcd/packet_send.[ch].
1041 * Purge the outgoing packet queue in the rekey protocol's final
1042 callback to assure that all rekey packets go to the network
1043 before quitting the protocol. Affected file silcd/server.c.
1045 * Added silc_client_packet_queue_parse as similar function as
1046 in server to the client library. The affected file is
1047 lib/silcclient/client.c.
1049 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Splitted silcd/server.c and created silcd/server_util.[ch]
1052 for utility functions.
1054 * Added new socket flag SILC_SF_DISABLED to indicate that the
1055 connection is open but nothing can be sent to or received from
1056 the connection. Affected file lib/silcutil/silsockconn.[ch].
1057 The checking for disabled socket is checked in the low level
1058 silc_socket_write and silc_socket_read functions.
1060 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Allow only nicknames and channel names that fits into the
1063 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1065 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1067 * When processing JOIN command reply in server check that if
1068 the channel exists in our global list we'll move it the local
1069 list. Affected file silcd/command_reply.c.
1071 * Fixed the check whether client is joined on the channel already
1072 in JOIN command. Affected file lib/silcclient/command.c.
1074 * Fixed the JOIN command reply to check whether the channel
1075 already exists. Affected file lib/silcclient/command_reply.c.
1077 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Added silc_ske_status_string to map the SKE error numbers
1080 to readable strings. The affected files are
1081 lib/silcske/silcske[_status].[ch].
1083 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Do not show the private channels on the WHOIS channel list
1086 as it is not allowed by the protocol. The affected file is
1089 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Assure that the packet length digged from the actual packet
1092 is something sensible in the silc_packet_decrypt_rest_special
1093 in lib/silccrypt/silcpacket.c.
1095 * Free and NULL the allocated pointer in silc_hmac_alloc if
1096 the HMAC allocation fails. The affected file is
1097 lib/silccrypt/silchmac.c.
1099 * Print the selected security properties to the log files in
1100 the server. Affected file silcd/protocol.c.
1102 * Add SKE's reference counter even if calling the completion
1103 callback manually. Otherwise it goes negative, although it
1104 does not cause any problems. The affected file is
1105 lib/silcske/silcske.c.
1107 * Remove the client entry with short timeout after giving the
1108 KILL command. Affected file lib/silcclient/command.c.
1110 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1111 case all found clients are already disconnected (WHOWAS would
1112 found them) in the server. Affected file silcd/command.c.
1114 * Update the last_receive (time of last data received) to be
1115 updated only when received private or channel message so that
1116 the idle time showed in WHOIS makes more sense.
1118 * Added boolean field `valid' in to the SilcClientEntry in the
1119 client library to indicate whether the entry is valid or not.
1120 This fixes the nickname change bug on channel when changing
1121 the nickname to be same than the old (like nick to Nick) the
1122 nickname formatter doesn't set the new nick anymore to Nick@host.
1123 Affected file lib/silcclient/idlist.[ch].
1125 * Now actually fixed the nickname changing on disconnection.
1126 Added new function silc_change_nick to the Irssi SILC Client.
1127 Affected file irssi/src/silc/core/client_ops.c,
1128 irssi/src/silc/core/silc-nicklist.[ch].
1130 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * Check that the public key exists in the GETKEY command before
1133 trying to encode it. Affected file silcd/command.c.
1135 * Print some notifications on received public keys with GETKEY
1136 command in the Irssi SILC Client. Affected files are
1137 irssi/src/fe-common/silc/module-formats.[ch],
1138 irssi/src/silc/core/client_ops.c.
1140 * Use IDENTIFY command to resolve the server information in the
1141 GETKEY command instead of INFO command. Affected file
1142 lib/silcclient/command.c.
1144 * All command reply functions in the client library now calls
1145 the pending command reply callbacks even if an error has
1146 occurred. The server has done this a long time and now it was
1147 time to move the client library to this as well. Now all
1148 errors can be delivered back to the pending command reply
1149 callbacks if necessary. Affected files are
1150 lib/silcclient/command[_reply].[ch].
1152 * Change the nickname on disconnection back to the username
1153 because in reconnect the server will enforce it to it anyway.
1154 Affected file irssi/src/silc/core/silc-servers.c.
1156 * Fixed a config file parsing bug in the Irssi SILC client.
1157 Affected file irssi/src/silc/core/clientconfig.c.
1159 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * When printing the channel mode on JOIN, verify that the
1162 channel key and channel's HMAC are valid. Affected file
1163 irssi/src/silc/core/client_ops.c.
1165 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1168 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1169 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1171 * Removed channel key rekey task deleting from the function
1172 silc_server_save_channel_key. Affected file silcd/server.c.
1173 Added explicit timeout task context instead that is used to
1174 delete the task if we are registering a new task before the
1175 new task has elapsed.
1177 * When channel key rekey occurs the client library now saves
1178 the old channel key for a short period of time (10 seconds) and
1179 is able to use it in case some is still sending channel
1180 messages encrypted with the old key after the rekey. Affected
1181 file lib/silcclient/[idlist.h|client_channel.c].
1183 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Added check to the silc_server_new_id_real to not accept
1186 new ID if it is the sender's own ID. Affected file is
1187 silcd/packet_receive.c.
1189 * Assure that we do not announce ourself or the one we've
1190 sending our announcements when we're router and are announcing
1191 servers to our primary router. Affected file silcd/server.c.
1193 * Fixed silc_server_command_identify_check_client to assemble
1194 correct WHOIS packet. It send corrupted WHOIS packet and
1195 caused problem with router to router connections. Affected
1196 file silcd/command.c.
1198 Fixed also silc_server_command_whois_check the same way
1199 as for the IDENTIFY command.
1201 * Added new SilcIDListStatus to the server in the SilcIDListData
1202 structure. The status now includes the current status of
1203 the entry (like registered, resolved etc.). Affected file
1204 silcd/idlist.[ch]. Defined a bunch of different status types
1205 as well. This replaced the old boolean registered field as well.
1207 Added resolve_cmd_ident field to the SilcClientEntry structure
1208 too so that if the entry is for example being resolved so
1209 another command may attach to the same pending command reply
1210 without requiring to resolve the same entry again. This concept
1211 should optimize the WHOIS and the IDENTIFY resolving under
1212 heavy load by taking away unnecessary resolving for entries
1213 that are being resolved already.
1215 Added support for adding multiple pending commands for one
1216 command idenfier. Affected file silcd/command[_reply].[ch].
1218 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1219 before deleting the data. Otherwise the hash table will have
1220 freed data in comparison functions. Affected file is
1221 silcd/command_reply.c.
1223 * Fixed silc_idlist_replace_client_id to add the new entry to
1224 the cache with NULL nickname. Otherwise there will be invalid
1225 memory as the nickname after the nickname is freed. Affected
1226 file silcd/packet_receive.c.
1228 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1229 saved into wrong slots because the previous number of entries
1230 was not taken into account. Affected file silcd/idlist.c.
1231 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1233 * If we are router and we receive JOIN notify to a channel that
1234 does not have any users then notified client is marked as the
1235 channel founder, as it is it. The affected file is
1236 silcd/packet_receive.c
1238 * Added to the extended hash table API's table_del_*ext functions
1239 the destructor as argument too, so that the caller can decide
1240 which destructor to use or whether to use destructor at all.
1241 Affected file lib/silcutil/silchashtable.[ch].
1243 * Fixed ID Cache purging. It actually deleted the entries from
1244 the hash table after the data was freed. The hash table ended
1245 up comparing freed memory. The affected file is
1246 lib/silccore/silcidcache.c.
1248 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Fixed Irssi SILC client's KILL command's HELP syntax.
1252 * The USERS command now resolves the detailed user information
1253 if the userinfo field is missing. Affected file is
1254 lib/silcclient/command_reply.c.
1256 * Do not print error in silc_file_read if the read file does
1257 not exist. Just silently return NULL. Affected file is
1258 lib/silcutil/silcutil.c.
1260 * Fixed the silc_log_output to not wine about NULL filename
1261 and to not create some bogus " " filename. Affected file is
1262 lib/silcutil/silclog.c.
1264 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Fixed various printing bugs on the user interface in the
1267 Irssi SILC Client. Minor changes that were forgotten from
1270 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Fixed the configure.in.pre and the compilation and distribution
1273 environment to support the new autoconf 2.52. That version is
1274 now required to compile the CVS trunk.
1276 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1279 to generally parse user@fqdn format strings. Affected file
1280 lib/silcutil/silcutil.c.
1282 * Added nickname_format and nickname_force_format fields to the
1283 SilcClientParams structure. The first one defines the format
1284 for the nicknames that the library will enforce if the receives
1285 multiple same nicknames. The second one is boolean value and
1286 can be used to force the library to always enforce the format
1287 to the nicknames regardles whether there are multiple nicknames
1288 or not. This configurable formatting was employed to flexibly
1289 support accessing multiple nicknames from the user interface.
1290 The userinterface can now set the nicknames to what ever format
1291 they prefer. Affected file lib/silcclient/silcapi.h.
1293 Added function silc_client_nickname_format to the file
1294 lib/silcclient/idlist.c. It performs the nickname formatting.
1296 Added new field `hostname´ to the SilcClientEntry context.
1297 It holds the hostname of the client. Affected file is
1298 lib/silcclient/idlist.h.
1300 * Irssi SILC Client sets the nicknames in nick@hostn format.
1301 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1302 irssi/src/silc/core/silc-core.c.
1304 The WHOIS printing now also shows both the real nickname and
1305 the formatted nickname so that user knows how to access the
1306 user if there are multiple same nicknames cached. Affected
1307 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1308 printing formatting too to take the hostname now as a separate
1309 argument. The Affected file is
1310 irssi/src/fe-common/silc/modules-formats.[ch].
1312 * Changed the silc_client_get_clients_local to accept the formatted
1313 nickname as argument. It accepts the real nickname too but the
1314 formatted nickname can be used to find the true entry from
1315 multiple entries. Affected file lib/silcclient/silcapi.h and
1316 lib/silcclient/idlist.c.
1318 * Added nickname_format_parse field to the SilcClientParams.
1319 It is a callback function provided by the application to parse
1320 the nickname out of the formatted nickname string. The library
1321 calls it to get the nickname from the formatted string. Since
1322 the application generally knows better the format of the nickname
1323 string it parses it instead of the library, even though library
1324 encodes the formatted string. If the callback function is not
1325 provided then the library will use the string as is. The
1326 affected file is lib/silcclient/silcapi.h.
1328 * All the nickname strings passed to the client library in
1329 commands are now expected to be formatted nickname strings.
1330 If the command does not support the formatted nickname string
1331 it will assume that the sent string is the actual nickname.
1332 Affected file lib/silcclient/command.c.
1334 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Added public key authentication support to OPER and SILCOPER
1337 commands in the client library. Affected file is
1338 lib/silcclient/command.c.
1340 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Changed the get_auth_methdod client operation to be asynchronous.
1343 It can be async if the application resolves the authentication
1344 method from the server during the negotiation. Added new
1345 SilcGetAuthMeth completion callback that the application will
1346 call after resolving the authentication method.
1348 Added function silc_client_request_authentication_method that
1349 the application can use to resolve the authentication method
1350 from the server. Added also SilcConnectionAuthRequest callback
1351 that the library will call after the server has replied. The
1352 application can call this function if it does not know the
1353 current authentication method.
1355 Affected files are lib/silcclient/client.c and
1356 lib/silcclient/silcapi.h.
1358 * The Irssi SILC client now automatically resolves the authentication
1359 method incase any configuration information is not present (and
1360 currently there never is). The affected file is
1361 irssi/src/silc/core/client_ops.c.
1363 * Fixed public key authentication from the client library.
1364 Affected file lib/silcclient/protocol.c. Changed also the
1365 protocol specification about the public key authentication in
1366 the connection authentication protocol. The actual data to be
1367 signed is now computed with a hash function before signing.
1369 * Fixed the public key authentication from the server as well.
1370 Affected file silcd/protocol.c.
1372 * Removed the mlock()'s from the memory allocation routines.
1373 Affected file lib/silcutil/silcmemory.c. The ./configure does
1374 not check anymore for the mlock(). Affected file is
1377 * Fixed USERS command in server to allow the execution of the
1378 command for private and secret channels if the client sending
1379 the command is on the channel. Affected file silcd/command.c.
1381 * Fixed silc_client_get_clients_local to return the clients
1382 count correctly. It could return wrong value. Affected file
1383 lib/silcclient/idlist.c.
1385 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1388 types. The assembler optimizations seemed not to like 64-bit
1389 data types. The assmebler optimizations thus are now enabled
1390 also for BSD systems as opposed to only enable them for Linux.
1392 * Do not check for threads at all on BSD systems. Affected
1393 file configure.in.pre.
1395 * Removed -n and -h options from the Irssi SILC Client since
1396 they are not used in silc.
1398 * Fixed the prime generation to assure that the first digit
1399 of the generated random number is not zero since our conversion
1400 routines does not like number strings that starts with zero
1401 digit. If zero digit is seen the random number is regenerated.
1402 This caused some corrupted RSA keys when the zero first digit
1403 was met. Affected file lib/silcmath/silcprimegen.c.
1405 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Fixed WIN32 configuration in the ./configure script.
1408 Fixed to include xti.h on environments that has it.
1409 Patches by Carsten Ilchmann and andrew.
1411 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Changed the silc_id_create_client_id to be collision
1414 resistant. It is now assured that there cannot be created
1415 two same client ID's. I suspect that some weird bugs in
1416 the server were actually caused by duplicate Client IDs.
1417 Affected file silcd/serverid.[ch]. A router receiving
1418 new ID now also assures and informs the sending server
1419 if the ID caused collision.
1421 * Changed the silc_id_create_channel_id to also assure that
1422 there are no collisions.
1424 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Statement about ignoring the Mutual Authentication flag when
1427 performing rekey with PFS was a bit misleading. It is ignored
1428 if it was set in the initial negotiation, it cannot be even
1429 set in the rekey. Fixed in the ke-auth draft. Started the
1430 new versions of the protocol drafts in the doc/.
1432 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Fixed a bug in silc_client_command_identify_save when saving
1435 new channel information. The channel name was no duplicated
1436 and caused crash on exit. Affected file is
1437 lib/silcclient/command_reply.c.
1439 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Fixed the getkey command handling in the server. Send just
1442 empty OK reply to the sender if the key could not be fetched
1443 (but everything else was ok, like the key just was not available).
1444 Changed the public key parameter to optional in the protocol
1445 specs so that empty OK reply can be sent. Affected file
1448 Added a message to Irssi SILC client to tell to user if the
1449 server did not return a public key.
1451 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Fixed a channel key regeneration bug. It registered new
1454 timeout tasks exponentially until all system resources were
1455 used. Affected file silcd/server.c.
1457 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Added the SILC Document generator to the scripts/silcdoc.
1460 It can be used to generate the Toolkit Reference Manual out
1461 of the source tree. Internally it will also use the RoboDoc
1462 generator now imported in util/robodoc.
1464 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Added couple of return's in rekey protocol if error orccurred
1467 during the protocol. The execution must be terminated.
1468 Affected file silcd/protocol.c. Also, terminate the protocol
1469 always with timeout.
1471 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * The client's Client ID was created initally from the wrong
1474 nickname (it could have been in format nick@host) in the
1475 silc_server_new_client. Affected file silcd/packet_receive.c
1477 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Added some SILC_LOG_ERROR's to various error conditions
1480 if client could not be added to ID cache. Affected files
1481 silcd/packet_receive.c and silcd/server.c.
1483 * When client's sock->user_data is freed, NULL also the
1484 client->router and client->connection pointers. Added check
1485 for these pointers being NULL to various places around the
1486 code. Affected file silcd/server.c.
1488 * Added client->data.registered == TRUE checks to various
1489 places around the code to assure that unregistered client's
1490 are not handled when it is not allowed. Affected file
1493 * Added `bool registered' fields to all
1494 silc_idlist_[server|client]_get_* routines to indicate whether
1495 the fetched client needs to be registered or not. Affected
1496 file silcd/idlist.[ch].
1498 * Add your own entry as registered to the ID cache in the
1499 server. Affected file server.c.
1501 * Fixed a bug in silc_server_new_server. The SilcServer was
1502 set as the new server's context instead of SilcServerEntry.
1503 This naturally caused some weird bugs.
1505 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Do not delete the channel rekey task when adding it
1508 for in silc_server_create_channel_key.
1510 * Changed the silc_server_create_channel_key to return
1511 TRUE or FALSE to indicate the success of the channel key
1514 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Fixed MSVC++ project files and added missing files to
1517 Makefiles under win32/.
1519 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Do not add TCP_NODELAY flag if the operating system
1522 does not have it defined. Affected files are
1523 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1525 * Fixed buffer overflow from Irssi SILC Client. Affected
1526 file irssi/src/fe-common/core/themes.c.
1528 * Fixed double free in client library in the file
1529 lib/silcclient/client.c when disconnecting from server.
1531 * Applied double free patch from cras to Irssi SILC client.
1532 Affected files irssi/src/core/[modules/expandos].c
1534 * Fixed the disconnection handling to Irssi SILC Client.
1535 The application must call silc_client_close_connection
1536 in ops->connect client operation in case of failure of
1537 the connection. Affected file is
1538 irssi/src/silc/core/client_ops.c.
1540 * Do not set sock->protocol to NULL in the function
1541 silc_client_close_connection after executing the protocol's
1542 final callback since the sock might not be valid anymore.
1543 Affected file lib/silcclient/client.c.
1545 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Do not enable SILC_THREADS if the linking with libpthread
1548 did not happen. Affected file configure.in.pre.
1550 * Added notion to protocol specification that server must
1551 verify the sent authentication payload with CMODE when
1552 setting the channel founder key. Implemented it to the
1553 server. Affected file silcd/command.c.
1555 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Added _EXTRA_DIST SILC distribution variable to the
1558 distributions file. It is used to conditionally add extra
1559 files or directories to the specific distribution. Affected
1560 files ./prepare, Makefile.am.pre and distributions.
1562 Removed the `_' from the start of the distribution names.
1565 * Added README.WIN32 for instructions to compile the Toolkit
1568 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1570 * Fixed a double free in disconnection in the server. Affected
1571 file is silcd/server.c.
1573 * Fixed the lib/silcske/groups.c to work now also with GMP
1574 MP library. The string conversion did not work when using
1575 specific base and the base is indicated in the string as well.
1577 * Created win32/ directory which now includes MSVC++ specific
1578 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1579 It will appear only in the toolkit distribution
1581 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Changed the key material distribution function in case when
1584 the hash output is too short. The data is now concatenated
1585 a bit differently than it used to. Made the change to the
1586 SKE protocol specification.
1588 * Added better GMP detection to configure.in.pre. A patch
1591 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Fixed a minor bug in SKE that might cause some problem on
1594 some platforms. Affected file lib/silcske/silcske.c.
1596 * Added the cookie checking for initiator in the SKE. It checks
1597 that the responder returns the sent cookie unmodified. The
1598 affected file is lib/silcske/silcske.c. Added new SKE
1599 error type INVALID_COOKIE that can be sent during the
1600 negotiation. Fixed some memory leaks as well.
1602 * Added the "invalid cookie" error message to Irssi SILC client's
1605 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1607 * Added `task_max' field to the SilcClientParams to indicate
1608 the maximum tasks the scheduler can handle. If set to zero,
1609 default values are used. Affected file lib/silcclient/silcapi.h.
1611 * Fixed memory leaks in silc_client_close_connection. Affected
1612 file lib/silcclient/client.c.
1614 * Added silc_client_del_client_entry to client library to free
1615 all memory of given client entry. Affected file is
1616 lib/silcclient/idlist.[ch].
1618 * Added new functions silc_client_del_channel and
1619 silc_client_del_server to delete channel and server entries.
1620 Affected file lib/silcclient/[silcapi.h/idlist.c].
1622 * Removed silc_client_del_client_by_id from silcapi.h.
1624 * Fixed the INFO command to return the server's own info
1625 correctly when querying by Server ID. Affected file is
1628 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Removed the non-blocking settings in WIN32 code in the
1631 silc_sock_[read/write] and added SleepEx instead. Affected
1632 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1633 of input data is now checked with FIONREAD and ioctlsocket.
1635 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Call silc_schedule_task_del_by_context in the
1638 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1639 Affected file lib/silccore/silcprotocol.c.
1641 * Call silc_protocol_cancel for active protocols in the
1642 silc_server_close_connection if the funtion
1643 silc_server_free_sock_user_data has not been called.
1644 Affected file silcd/server.c.
1646 * Generic tasks cannot be deleted using the del_by_fd
1647 task deleting function since generic tasks does not match
1648 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1650 * Added a notion to SILCOPER help file that the SILCOPER works
1651 only on router server, not on normal server.
1653 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Added for WIN32 support for the new scheduler as well.
1656 Affected file lib/silcutil/win32/silcwin32schedule.c.
1658 * Fixed the SHA1 implementation to work on various platforms.
1660 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1663 API. It is part of the scheduler now. Everything else is
1664 as previously but some functions has changed their names.
1665 Checkout the lib/silcutil/silcschedule.h for the interface.
1666 Updated all applications to use the new interface. Affected
1667 files are lib/silcutil/silcschedule.[ch].
1669 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1671 * Found a bug in the SKE implementation. The HASH value,
1672 specified by the protocol, was not computed correctly. The
1673 public key of the responder was not added to the computation
1674 even though it is mandatory. Affected file lib/silcske/silcske.c.
1675 This unfortunately causes incompatibilities with older
1676 clients and servers.
1678 * Added WIN32 specific network init and uninit functions:
1679 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1680 the Winsock2. Affected file lib/silcutil/silcnet.h and
1681 lib/silcutil/win32/silcwin32net.c.
1683 * Set the socket always to nonblocking mode on WIN32 after
1684 reading data or writing data. Affected file is
1685 lib/silcutil/win32/silcwin32sockconn.c.
1687 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Fixed various compilation problems under WIN32. Affected
1690 files lib/silcutil/win32/silcwin32thread.c and
1691 lib/silcutil/win32/silcwin32schedule.c.
1693 * Removed all _internal.h #includes from public header
1694 files. Internal headers must never be included from
1697 Removed also the lib/silcske/payload_internal.h file.
1699 * All include files that may be needed (public and some others
1700 included by the public headers) by application developers are
1701 now copied to the ./includes directory. It does not copy any
1702 internal headers. Affected file Makefile.defines.pre and all
1703 Makefile.am's under lib/ and subdirs.
1705 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Do not change the ~/.silc directory's permissions automatically.
1708 Affected file irssi/src/silc/core/clientutil.c.
1710 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Do not cancel the protocol in silc_server_close_connection
1713 it might cause recursion. Now cancelled in the function
1714 silc_server_free_sock_user_data. Affected file silcd/server.c.
1716 * Fixed the silc_server_remove_clients_by_server to regenerate
1717 the channel keys correctly finally. Added also new function
1718 silc_server_remove_clients_channels to actually do it.
1719 Affected file silcd/server.c.
1721 * Fixed the silc_server_new_channel to not crash by giving
1722 wrong router to the new channel. Affected file is
1723 silcd/packet_receive.c.
1725 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1727 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1728 which is given as argument to the silc_client_alloc now.
1729 It can be used to configure the client and set various parameters
1730 that affect the function of the client.
1732 * The USERS command in server did not check whether the channel
1733 is private or secret. Affected file silcd/command.c.
1735 * Added new argument to the USERS command in protocol specification.
1736 The USERS command now can take the channel name as argument
1737 as well. Added support for this in client and server and
1738 updated the protocol specs.
1740 * Completed the GETKEY command in client. It can be now used
1741 to fetch also servers public key not only some clients.
1742 Affected files lib/silcclient/command[_reply].c.
1744 * Added silc_client_get_server to return server entry by the
1745 server name. Affected files lib/silcclient/silcapi.h and
1748 * Redefined the IDENTIFY command in protocol specification to be
1749 more generic. It now can be used to query information about
1750 any entity in the SILC Network, including clients, servers and
1751 channels. The query may be based either the entity's name
1752 or the ID. Added support for this in both client and server.
1754 Affected files silcd/command.c and lib/silcclient/command.c
1755 and command_reply.c.
1757 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1758 the _from_client and _from_server functions. Affected file
1761 * Added silc_client_get_channel_by_id_resolve to the file
1762 lib/silcclient/silcapi.h to resolve channel information by
1763 its ID. Added also silc_client_get_channel_by_id that
1764 does not resolve it from the server.
1766 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Added SilcServerEntry context into the client library
1769 to represent one server. The INFO command now allocates
1770 these to save the resolved server info. For now on the
1771 client library will also keep information about servers,
1772 connected and resolved with INFO.
1774 The INFO command now allocates the SilcServerEntry context
1775 and saves the server info there. The COMMAND_REPLY in
1776 the INFO now returns the parameters to application in
1777 same order as defined in the protocol specification.
1779 The entries are cached in the client->server_cache.
1781 * The INFO command is now issued after received the Client ID
1782 from the server. Affected file lib/silcclient/client.c.
1784 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1785 to the application as the mode changer might be server.
1786 It is guaranteed that NULL is not returned anymore to the
1787 application. Affected file lib/silcclient/client_notify.c.
1789 The ID Type is now also passed to the application so that
1790 it can check whether the returned entry is SilcClientEntry
1793 Added new function silc_client_get_server_by_id to return
1794 the server entry by ID. Affected files are the
1795 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1797 * Do not create the channel in the Irssi SILC Client when issuing
1798 the JOIN command but when received the sucessful JOIN command
1799 reply. Otherwise the channel might get created even though we
1800 could not join it. The Affected file is
1801 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1803 * Fixed a channel joining bug in router. The router must also
1804 check the channel modes, invite and ban lists etc. when serving
1805 the JOIN command sent by normal server. Affected file is
1806 silcd/command.c. The router now resolves the client's
1807 information from the server who sent the JOIN command if it
1808 does not know it, and processes the JOIN command only after
1811 * Changed the SilcCommandCb to take new argument; void *context2.
1812 Affected file lib/silccore/silccommand.h
1814 The second argument in the command callbacks in the server now
1815 includes the SilcServerCommandReplyContext if the command was
1816 called as pending command callback from the command reply.
1817 Otherwise it is NULL. When called as pending the status of the
1818 command reply will be checked and if it was erronous the
1819 error will be sent to the original sender of the command.
1820 This way the client always receives the error messages even
1821 though the server was actually the one who received the error
1822 when it resent the command to router, for example. Affected
1823 files silcd/command[_reply].[ch].
1825 * Fixed sending WHOWAS command's error message to client if
1826 the requested client could not be found. It was missing.
1829 * Changed the CMODE and CUMODE commands reply arguments in the
1830 protocol specification. The Channel ID is now sent in both
1831 of the commands to identify the channel. Implemented this
1832 new feature to the client and server. Affected files
1833 lib/silcclient/command_reply.c and silcd/command.c.
1835 * Made better checks for invite and ban lists in the JOIN
1836 command in server. Affected file silcd/command.c.
1838 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * The server now performs the incoming host IP/DNS lookup
1841 using the silc_socket_host_lookup and thus does not block
1842 the server anymore. Affected file silcd/server.c.
1844 * Completed the multi-thread support for SILC Scheduler in
1845 the lib/silcutil/silcschedule.c.
1847 * Fixed the configure.in.pre to detect the pthread correctly
1850 * Fixed a deadlock in silc_task_queue_wakeup in the file
1851 lib/silcutil/silctask.c.
1853 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * Added new function silc_schedule_wakeup that is used in
1856 multi-threaded environment to wakeup the main thread's
1857 schduler. It needs to be used when a thread adds a new task
1858 or removes a task from task queues. After waking up, the
1859 scheduler will detect the task queue changes. If threads
1860 support is not compiled in this function has no effect.
1861 Implemented the wakeup mechanism to both Unix and WIN32
1862 systems. Affected files are lib/silcutil/silcschedule.[ch],
1863 lib/silcutil/unix/silcunixschedule.c and the
1864 lib/silcutil/win32/silcwin32schedule.c.
1866 * Added new function silc_task_queue_wakeup to wakeup the
1867 scheduler by the specified task queue. Affected file
1868 lib/silcutil/silctask.[ch].
1870 * The silc_socket_host_lookup_start now wakes up the scheduler
1871 after adding the timeout task. Affected file is
1872 lib/silcutil/silcsockconn.c.
1874 * The silc_socket_host_lookup is synchronous now if the threads
1875 support is not compiled in. However, the callback is still
1876 called asyncronously through the scheduler, anyway. Affected
1877 file lib/silcutil/silcsockconn.c.
1879 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Added new function silc_socket_host_lookup to perform
1882 asynchronous IP and FQDN lookups for the socket connection.
1883 Affected files lib/silcutil/silcsockconn.[ch].
1885 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1888 that may or may not compile the mutex support in.
1890 Changed the silc_mutex_alloc interface. It allocates the
1891 mutex now to the sent pointer and returns TRUE or FALSE.
1893 Affected file lib/silcutil/silcmutex.h.
1895 * Wrote the SILC Task Queue interface to support multi-threads.
1896 Affected file lib/silcutil/silctask.[ch].
1898 * Wrote the SILC Scheduler to support multi-threads. Affected
1899 file lib/silcutil/silcschedule.c.
1901 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1904 in lib/silcutil/win32/.
1906 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Defined SILC Mutex API and SILC Thread API and implemented
1909 them for Unix. Affected files are
1910 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1911 lib/silcutil/unix/silcunixmutex.c and
1912 lib/silcutil/unix/silcunixthread.c.
1914 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1916 * Fixed the silc_server_remove_clients_by_server's channel
1917 key re-generation. The hash table handling was incorrect
1918 and would not work with many channels. Affected file is
1921 * Fixed some memory leaks around the server code.
1923 * Rewrote the silc_server_get_users_on_channel to support IPv6
1924 based Client ID's. Affected file silcd/server.c.
1926 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1927 specification. However, a separate document must be written
1928 to define the detailed signing procedure and the payload
1929 associated with the flag. Defined the flag to the
1930 lib/silccore/silcchannel.h as well.
1932 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Changed the dynamic tables to static size tables in the
1935 lib/silccrypt/silchmac.c.
1937 * Removed GCC dependencies from the code. A patch by cras.
1939 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Do not show the error "Error receiving packet bla bla"
1942 in server if it really was not an error (-2 means that reading
1943 is pending). Affected file silcd/server.c.
1945 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Fixed a possible crash in silc_server_remove_clients_by_server
1948 in silcd/server.c. Fixed there also some memory leaks.
1950 * Fixed the silc_idlist_replace_client_id. It could replace
1951 wrong key in the hash table. Affected file silcd/idlist.c.
1953 * Do not check whether there are global users on the channel
1954 if the channel->global_users is FALSE. Affected functions
1955 silc_server_remove_from_one_channel and
1956 silc_server_remove_from_channels in silcd/server.c. Also,
1957 do not check if the removed client is local as we can be
1958 sure that global client was not removed from the channel
1959 and checking for global users is not needed.
1961 * The silc_server_remove_clients_by_server now re-generates
1962 the channel keys correctly for those channels that had
1963 clients removed from them. Affected file silcd/server.c.
1965 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Found the reason of random crashes in the server. We weren't
1968 ignoring the SIGPIPE signal (which can be sent in write())
1969 and it crashed the server. Affected file silcd/silcd.c.
1971 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Assure that sock->user_data is not NULL in the function
1974 silc_server_packet_send in silcd/packet_send.c.
1976 * Disconnect the remote connection if it could not be added
1977 to any ID lists in the server. The affected file is
1980 * Check in silc_server_packet_send[_real/dest] that the
1981 socket is not disconnecting and ignore the data if it is.
1982 Affected file silcd/packet_send.c.
1984 * Define inline to __inline on native WIN32 compilation.
1985 Affected file includes/silcwin32.h.
1987 * Added some explicit type casts for inline code since MSVC
1988 require them. Affected files lib/silcutil/silcbuffer.h,
1989 lib/trq/silcdlist.h and lib/trq/silclist.h.
1991 * Print warning in log files from now on if the packet
1992 decryption fails. Affected file silcd/server.c.
1994 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Changed the `say' client operation's interface to accept
1997 new `type' argument to indicate the type of the message sent
1998 by the library. The application may filter the library's
1999 messages according the type. The affected file is the
2000 lib/silcclient/silcapi.h.
2002 * Added two new functions to lib/silcclient/silcapi.h:
2003 silc_client_del_client and silc_client_del_client_by_id.
2004 Affected file lib/silcclient/idlist.c.
2006 * Moved the clientincludes.h from includes/ to silc/ and
2007 serverincludes.h from includes/ to silcd/.
2009 * The modes for the CMODE and CUMODE are now passed as
2010 uint32 for application with COMMAND_REPLY. The affected
2011 file is lib/silcclient/command_reply.c.
2013 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2015 * /WHOIS without arguments shows client's own information.
2016 Affected file lib/silcclient/command.c.
2018 * Changed PING to not accept any arguments. The specs
2019 says that client can ping only the connected server so
2020 requiring an argument is not needed. Affected file is
2021 lib/silcclient/command.c.
2023 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2025 * Fixed a fatal bug in private message sending and reception
2026 encryption and decryption when using private message keys.
2027 The implementation was incorrect and did not follow the
2028 specification. It causd that some of the message were
2029 lost since it did not use the sending and receiving keys
2030 as the protocol suggests. This has been fixed and will cause
2031 incompatibilities with older clients when sending private
2032 message encrypted with private message keys. Affected files
2033 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2034 and various other in Irssi SILC Client.
2036 Added `responder' boolean argument to the functions
2037 silc_client_add_private_message_key[_ske] to indicate when
2038 the key is added as responder or initiator of the key
2041 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Removed the silc_ske_check_version function and created
2044 a SilcSKECheckVersion callback. Added also a function
2045 silc_ske_set_callbacks that is now used to set all SKE
2046 callbacks. The callback functions are not given to
2047 the SKE functions anymore, but this function is used to
2050 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2052 * Added `silc_version' argument to the silc_client_alloc
2053 to define the version of the application for the library.
2054 The library will use the version string to compare it
2055 against the remote host's (usually a server) version
2056 string. Affected file lib/silcclient/silcapi.h
2058 * Added the KE protocol context to Key Agreement context
2059 in client library so that we can abort the SKE if it
2060 is in process when we get timeout. Affected file is
2061 lib/silcclient/client_keyagr.c.
2063 * Do not resolve the client ID forever if it returns in the
2064 first time that such client does not exist. This was done
2065 for example with private message. Affected file is
2066 lib/silcclient/client_prvmsg.c.
2068 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Do not add regex.h for WIN32. The affected file
2071 includes/silcincludes.h.
2073 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2074 not work yet 100%. It generates the DLL's automatically
2075 when compiling with --with-win32 under cygwin.
2077 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * lib/contrib/regex.c is not compiled on WIN32.
2081 * Added silc_net_get_socket_opt function to the
2082 lib/silcutil/silcnet.h.
2084 * Added includes/silcwin32.h for WIN32 specific includes
2087 * Do not use ptime structure or any of the posix process
2088 functions on WIN32 in lib/silccrypt/silrng.c.
2090 * Added silc_gettimeofday to provide generic function
2091 for struct timeval on all platforms. Added the function
2092 to lib/silcutil/silcutil.h.
2094 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2097 library as they clearly belong there. As a plus side we
2098 can make the actual socket connection routines platform
2101 Added also new generic function silc_socket_read and
2102 silc_socket_write (that used to be silc_packet_[read/write].
2103 The implementation of these are platform specific.
2105 * Added WIN32 specific routines of silc_socket_[read/write]
2106 to lib/silcutil/win32/silcwin32sockconn.c.
2108 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Added preliminary support for native WIN32 compilation under
2111 cygwin (using the -mno-cygwin option for GCC) to the
2112 ./configure.in.pre. The --with-win32 now prepares the
2113 compilation for native WIN32.
2115 * Rewrote the SILC Scheduler interface in the file
2116 lib/silcutil/silcschedule.h. The scheduler is now context
2117 based and does not have anymore any global static scheduler.
2118 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2119 and created lib/silcutil/win32 directory for WIN32 based
2122 * Added Unix specific network routines to the
2123 lib/silcutil/unix/silcunixnet.c and the old
2124 lib/silcutil/silcnet.c includes now only generic routines.
2126 Added WIN32 specific network routines to the
2127 lib/silcutil/win32/silcwin32net.c.
2129 * Added Unix specific utility functions from the
2130 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2132 * Added WIN32 SILC Scheduler to the file
2133 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2136 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Do not handle JOIN notify in the server if the target client
2139 is not registered (idata->registered == FALSE). The affected
2140 file is silcd/packet_receive.c.
2142 * Update the nickrec->founder in event_cumode in the Irssi SILC
2143 client. Affected file irssi/src/silc/core/silc-channels.c.
2145 * Fixed the CUMODE_CHANGE notify handling in the server when
2146 server and router are announcing their clients on channels.
2147 Now the mode changes are saved and notified correctly. The
2148 affected file is /silcd/packet_receive.c.
2150 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2151 They really did not replace the cache entry in the ID Cache.
2152 Now they do that. Affected file silcd/idlist.c.
2154 * Fixed the KICK notify handling in the Irssi SILC client to
2155 update the channel records so that the kicked client does not
2156 appear to be on the channel. The affected file is
2157 irssi/src/silc/core/silc-channels.c.
2159 * Always update the conn->current_channel when executing command
2160 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2162 * Fixed the KILL notify handling in Irssi SILC client to remove
2163 the killed client on all channels.
2165 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Fixed the silc_parse_command_line to remove extra spaces
2168 from the start and end of the arguments. Affected file is
2169 lib/silcutil/silcutil.c.
2171 * Cancel and free any active protocol in the function
2172 silc_server_close_connection. Affected file silcd/server.c.
2174 * Cancel and free any active protocol in the function
2175 silc_client_close_connction. Affected file is
2176 lib/silcclient/client.c.
2178 * Do not execute the KILL command for clients that are in
2179 history (ie. they are not in the network). Affected file is
2182 * Fixed KILL notify handling, client does not crash anymore.
2183 Affected file irssi/src/silc/core/silc-channels.c.
2185 * Reduced the default packet buffer size from 2048 to 1024 in
2186 lib/silccore/silcpacket.c.
2188 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2189 counter to the SKE context that is incresed when the SKE library
2190 performs async operation outside the library. If the outside
2191 process frees the SKE context and FREED status will be set
2192 and the library will detect after the sync operation that the
2193 libary is freed. The affected files are
2194 lib/silcske/silcske[_status].[ch].
2196 * Resolve the client entry information in the function
2197 silc_client_channel_message to assure that NULL pointer is not
2198 passed as client entry to the application. */
2200 * Fixed the task timeout calculation to assure that there is
2201 never negative timeouts. The affected file is
2202 lib/silcutil/silcschedule.c.
2204 * Fixed the channel user mode notification sending in server.
2205 It was sent point-to-point to the router (or to server by router)
2206 but it needs to be destined to a channel. The routines now
2207 supports sending the channel user mode notifys to the channels
2208 when announcing clients and channels. Affected files are
2209 silcd/server.c and silcd/packet_receive.c.
2211 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2212 It did not actually replace the old channel entry in the cache.
2213 Affected file lib/silcclient/client_notify.c.
2215 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Fixed a possible crash in silc_packet_send_prepare. It now
2218 assures always that there is enough space in the buffer and
2219 at the tail area of the buffer (for MAC).
2221 Fixed the inbound buffer reallocation in silc_packet_read.
2222 It was old code and did not handle the reallocation correctly.
2225 The affected file is lib/silccore/silcpacket.c.
2227 * Fixed buffer overflow in silc_parse_nickname in the file
2228 lib/silcutil/silcutil.c.
2230 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * make install generates new server keys only if there is not
2235 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2238 Added check that if the NOREPLY is set then we will not send
2239 the away message. This avoids infinite loop of away messages
2240 if both clients are away. The affected file is
2241 lib/silcclient/client_prvmsg.c.
2243 * Fixed client crash if /NICK was given without arguments.
2244 Affected file lib/silcclient/command.c.
2246 * Server does not send the invite list in INVITE command back
2247 to the client if the list was not altered. Added this notion
2248 to the protocol spec as well. Affected file silcd/command.c.
2250 Fixed possible crash in INVITE command by checking the
2251 value of silc_server_get_client_route command.
2253 * Fixed the INVITE notify type handling. The arguments are now
2254 taken in correct order and client does not crash. The affected
2255 file is irssi/src/silc/core/silc-channels.c.
2257 Removed the "Inviting xxx to channel" message from the
2258 client library away and let the application handle it.
2259 Affected file lib/silcclient/command.c. Added that message
2260 to Irssi SILC client's message formats.
2262 * Fixed CMODE command crash in client. It now checks the
2263 amount of arguments correctly and does not crash. The affected
2264 file is lib/silcclient/command.c.
2266 * Do not create new channel automatically in silc_channels_join
2267 but check whether the channel by that name already exists.
2268 Affected file irssi/silc/core/silc-channels.c.
2270 * Do not send the SERVER_SIGNOFF to router if the disconnected
2271 entity was the router. Affected file silcd/server.c.
2273 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2274 SILC client as it was missing from there.
2276 Added the handling of the KICK notify to the Irssi SILC client
2277 as it was missing. Added "you have been kicked" message to
2278 Irssi SILC client's message modules formats.
2280 Added the handing of the KILL notify to the Irssi SILC client
2281 as it was missing. Added the kill message module formats
2284 The affected file is irssi/src/silc/core/silc-channels.c.
2286 * The router did not save the channel mode the server announced.
2287 Affected file silcd/packet_receive.c.
2289 * Fixed a possible crash in INFO command in server. If the
2290 server did not provide the server info it crashed. Affected
2291 file silcd/command.c.
2293 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Fixed the GETKEY command in the server to check also the
2296 global list. Otherwise the GETKEY would not work correctly
2297 in normal SILC server. Affected file silcd/command.c.
2299 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Fixed GETKEY crash, it crashed if the command did not succseed.
2303 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2306 is now real and not just an macro interface to GMP.
2308 Removed the entire GMP from the source tree and imported new
2309 NSS MPI library instead. Reason for removing GMP is that it is
2310 extremely large and compiles extremely slow. The NSS MPI
2311 is only a few files and compiles in less than 10 seconds.
2312 The speed is also about the same as GMP. The MPI is imported
2313 to lib/silcmath/mpi.
2315 If the system has GMP installed we will still use the GMP.
2316 If it is not then the NSS MPI will be compiled.
2318 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Merged a long nickname (127 characters long) crash bugfix from
2321 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2323 * Merged a freed memory reference bugfix from Irssi CVS tree.
2324 Affected file irssi/src/core/commands.c.
2326 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Added the server's public key sving and verification to the
2329 server when performing the SKE. This was missing and the
2330 remote server's (or router's) public key was accepted without
2331 checking whether we have it previously or trust it at all.
2332 Affected file silcd/protocol.c.
2334 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2336 * Check in the silc_server_timeout_remote if protocol is active
2337 and make sure that the protocol's final callback is called so
2338 that all memory if freed. Affected file silcd/server.c.
2340 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * silc_server_whois_send_reply crashed the server if the nickname
2343 was 127 characters long. Affected file silcd/command.c.
2345 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Added sanity check to the silc_server_new_client. If the hostname
2348 is provided inside username then check that the provided hostname
2349 really is the same as the resolved one. If the hostname was not
2350 resolved then check it from the public key. Affected file is
2351 silcd/packet_receive.c.
2353 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2354 if the server disconnected us and the connection is not valid
2355 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2357 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2358 the library to the lib/silcutil/silcutil.[ch].
2360 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Close log file after open. Affected file
2363 lib/silcutil/silclog.c.
2365 * Check whether sock == NULL in silc_client_send_packet and return
2366 if it is. Affected file lib/silcclient/silcclient.c.
2368 * Check rec->entry == NULL in the Irssi SILC Client before
2369 sending the channel message. Affecte file is
2370 irssi/src/silc/core/silc-servers.c.
2372 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Merged a splitted window bugfix from Irssi CVS tree. The
2375 affected file is irssi/src/fe-text/textbuffer-view.c.
2377 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2378 It did not print nickname.
2380 * Improved the distributions system a bit.
2382 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2385 irssi/src/fe-text/gui-window.c.
2387 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2388 to in-active server. The affected file is
2389 irssi/src/silc/core/client_ops.c.
2391 * Resolve the client in USERS command reply if the entry does
2392 not have username resolved. The affected file is
2393 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2394 command to WHOIS command to really resolve stuff. The USERS
2395 is not used any more in any critical section so WHOIS can
2396 be used even though it might be slower than IDENTIFY.
2398 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2401 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Changed the protocol API a bit more consistent in the
2404 lib/silccore/silcprotocol.[ch].
2406 * Changed the following headers to ROBODoc format:
2408 lib/silccore/silcpayload.h
2409 lib/silccore/silcprotocol.h
2410 lib/silccore/silcsockconn.h
2412 All core library headers are now formatted.
2414 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Fixed a bug in Irssi SILC client; do not show that you are
2417 server/router operator if you really are not. Affected file is
2418 irssi/src/silc/core/client_ops.c.
2420 * Renamed silc_command_free_payload to silc_command_payload_free.
2421 Affected file lib/silccore/silccommand.h
2423 * Added silcmath.h to include the prototoypes of various routines
2424 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2427 * Changed the following headers to ROBODoc format:
2429 lib/silccore/silcchannel.h
2430 lib/silccore/silccommand.h
2431 lib/silccore/silcid.h
2432 lib/silccore/silcidcache.h
2433 lib/silccore/silcmode.h
2434 lib/silccore/silcnotify.h
2435 lib/silccore/silcpacket.h
2436 lib/silcmath/silcmath.h
2438 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Added checking to the server code not to start the server if
2441 ciphers and stuff are not configured properly. Affected files
2442 silcd/serverconfig.[h] and silcd/server.c.
2444 * Changed the layout of the header files of the public interfaces
2445 in the SILC libraries. The new layout supports ROBODoc
2446 documentation tool (and some others) so that it is easy to create
2447 a library reference manual. All the other headers and source
2448 code must still follow the CodingStyle document. Also source
2449 code must not include these ROBODoc stuffs, only the headers.
2450 Furthermore, all public interface headers must now be named
2451 by using `silc' prefix, example: silcapi.h, silccipher.h.
2452 Some files were renamed due to this. All the other headers
2453 must not be used as public interfaces. I will update the
2454 CodingStyle document later. Changed following headers, so far:
2456 lib/silcclient/silcapi.h
2457 lib/silccore/silcauth.h
2458 lib/silccore/silcprivate.h
2459 lib/silccrypt/silcdh.h
2461 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Removed silc_client_packet_send_flush from the client library
2466 as it is not needed. Affected file lib/silcclient/client.[ch].
2468 * Added printing of message of unresolved authentication method
2469 to the Irssi SILC client. Added it to the module formats.
2470 Removed the same message from the client library.
2472 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Added new distribution feature, DISTLABEL. Every distribution
2475 can define own preprocessor label that can be used in the
2476 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2477 file distributions, acconfig.h.pre and prepare.
2479 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Added Makefile.defines_int to include the actual definitions
2482 for Makefile.defines.in. Tested the new distribution system,
2483 created distributions and tested installation.
2485 * Added AWAY message printing to the Irssi SILC client. Added
2486 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2488 * Added SCONNECT command to call the SILC's CONNECT command.
2489 Cannot use CONNECT directly since Irssi uses that internally.
2490 Affected file irssi/src/silc/core/silc-servers.c.
2492 Added ACTION local command. It is same as ME command but takes
2493 the channel as mandatory argument.
2495 Rewrote some of the Irssi's help files to suite for SILC
2498 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Added Makefile.defines[.in] that should for now on be included
2501 in all Makefile.am file in the source tree. That file includes
2502 all common compilation definitions for SILC source tree.
2504 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Minor changes to the ./prepare script to change the package
2507 name according the distribution name to the configure.in.
2509 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Created new distribution system. Added file `distributions'
2512 that defines all the distributions that can be created out of
2513 the SILC source tree. The ./prepare script now reads that
2514 file to determine how to prepare the distributions. The
2515 first argument to the ./prepare is the name of the distribution
2516 and second is the version of the distribution. If given
2517 without arguments it creates the default (toolkit) distribution
2518 with the default version (defined in ./prepare).
2520 All Makefile.am files that are subject to the distributions
2521 are now named as Makefile.am.pre. These are ./Makefile.am
2522 and lib/Makefile.am. Others may be changed later.
2524 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Added invite list, ban list, some key management and connection
2527 error message printing to module formats in the Irssi SILC client.
2529 * Added new silc_client_set_away_message to set the away message
2530 that is back to the person who sent private message. The
2531 affected file lib/silcclient/silcapi.h and the
2532 lib/silcclient/client_prvmsg.c.
2534 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Fixed the private message sending in the Irssi SILC client,
2537 added local command KEY to the Irssi SILC client.
2539 Added key management and key agreement message formats to the
2540 irssi/src/fe-common/silc/module-formats.[ch].
2542 Added USERS (alias WHO) printing, server/router operator
2543 indication and LIST command printing to the module formats.
2545 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Fixed channel joining notify handling, cumode notify handling
2548 from Irssi SILC client.
2550 * Added SILC specific module-formats to the Irssi SILC client so
2551 that SILC specific message hilighting, colors etc is possible.
2552 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2554 Added channel mode, channel user mode, actions, notices,
2555 whois and whowas printing to the the module-formats.c.
2557 * Fixed a bug in channel deletion in the server. The channel
2558 is not left to the cache even if the channel founder auth mode
2559 is set when there are no users anymore on the channel. Affected
2560 file silcd/server.c.
2562 * The silc_net_localhost now resolves the entire hostname including
2563 the domain name. Affected file lib/silcutil/silcnet.c.
2565 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Changed the ask_passphrase client operation to be ascynchronous.
2568 It has now a completion callback and a context that the
2569 application must call after it has got the passphrase from
2570 the user. Affected files lib/silcclient/silcapi.h,
2571 lib/silcclient/protocol.c, lib/silcclient/command.c and
2574 Added SilcAskPassphrase callback that the application calls
2575 to deliver the passphrase to the library.
2577 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2578 The public key verification and especially a certificate
2579 verification is asynchronous procedure.
2581 Added new SILC_SKE_STATUS_PENDING status to indicate the
2582 request is pending and a callback will be called to finalize
2585 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2586 indicate that remote end did not send its public key (or
2587 certificate), even though we require it. Added check for this
2588 condition in the SKE. This was a security bug, now fixed.
2590 Defined new SilcSKEVerifyCbCompletion callback that is called
2591 when the verification process is completed.
2593 The affected files lib/silcske/silcske_status.h and
2594 lib/silcske/silcske.[ch].
2596 * Changed the verify_public_key client operation to be async
2597 as well. Defined SilcVerifyPublicKey callback that is used to
2598 indicate the success of the public key verification process.
2600 Changed the server and client to use the new async client
2603 * Changed the Irssi SILC client's internal scheduler to be called
2604 twice as many times as it used to be. As a result the client
2605 should be a bit faster now. Affected file is
2606 irssi/src/silc/core/silc-core.c.
2608 * Added support to Irssi SILC client of asynchronous public key
2609 verification and passphrase inquiry. Affected file is
2610 irssi/src/silc/core/silc-core.c.
2612 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Do not say "You have left channel %s" in client library.
2615 Moved it to the application. Affected files are
2616 lib/silcclient/command.c and silc/client_ops.c.
2618 * Fixed silc_client_get_clients. Command context was not
2619 duplicated and was freed memory in the callback. Affected
2620 file lib/silcclient/idlist.c.
2622 * Do not say "you are now talking..." on JOIN command in the
2623 client library. The appliation must handle it.
2625 * Do not say ".. changed topic to" in command reply in the
2626 client libary. The application must handle it.
2628 * Fixed TOPIC command sending in the client library.
2630 * Fixed a memory leak in silc_client_command_free in the file
2631 lib/silcclient/command.c.
2633 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Imported a modified version of Irssi client to the source tree.
2636 The Irssi will be used to create a new client called
2637 Irssi SILC. Imported to irssi/.
2639 Added silc_core_init_finish function to the Irssi. Affected
2640 file irssi/configure.in.
2642 A lot changes in the Makefile.ams around the irssi tree.
2644 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Do not rehash if the new size is same as the old size of the
2647 hash table, in the silc_hash_table_rehash*. The affected file
2648 lib/silcutil/silchashtable.c.
2650 * Replaced hash_table_del_by_context calls from the server
2651 (when channel->user_list and client->channels) to the
2652 hash_table_del as it is sufficient and faster.
2654 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Added silc_hash_table_list, silc_hash_table_get and the
2657 SilcHashTableList structure to provide an alternative way to
2658 traverse the hash table. The affected files are
2659 lib/silcutil/silchashtable.[ch].
2661 * Changed the server's idlist routines to use the hash table
2662 routines to optimize the code.
2664 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Replaced the client entry's `channel' list and channel entry's
2667 `user_list' list to hash tables for optimized lookup. Changed
2668 the code to use the hash table interface around the code.
2669 Affected file lib/silcd/idlist.[ch].
2671 * Added `auto_rehash' boolean argument to the function
2672 silc_hash_table_alloc to indicate whether the hash table should
2673 auto-rehash when it thinks is appropriate time. It will
2674 increase the hash table size if the there is twice as much
2675 entries in the table than the size of the table, and will
2676 decrease the size if there are twice as less entries than
2677 the size of the table.
2679 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2683 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * silc_idcache_purge_by_context deletes the entry now by context
2686 as it is supposed to do. Affected file lib/silccore/idcache.c.
2688 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2689 client is not anymore valid (WHOWAS givens the info) and not
2690 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2692 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Removed the `data' and `data_len' arguments from the ID Cache
2695 interfaces and added `name' argument. ID Cache does not handle
2696 anymore the binary data only a names associated with given ID.
2698 * When hashing a Client ID with silc_hash_id the entire ID is
2699 not hashed anymore, instead only the hash of the Client ID is
2700 hashed. This way we can access the Client ID from the cache
2701 with Client ID but with the hash of the ID (which is a hash of
2702 the nickname) as well without any difference in performance.
2704 Added also silc_idcache_find_by_id_one_ext to do one on one
2705 searching when we have the actual ID. Added also function
2706 silc_hash_client_id_compare. The affected files are
2707 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2709 * When hashing the name associated with a ID it is always done
2710 in lowercase. This way we can access the cache without worrying
2711 about case-sensitivity, even though, for example nicknames are
2714 * Fixed a bug in server with channel message sending. It put
2715 wrong ID type as destination ID. The affected file
2716 silcd/packet_send.c.
2718 * silc_idcache_del_by_context now deletes from all hash tables
2719 by context. Affected file lib/silccore/idcache.c.
2721 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Changed the client library to use the new ID Cache interface.
2724 Changes around the source tree.
2726 * Added silc_hash_table_rehash_ext to rehash with specific
2727 hash function. Affected file lib/silcutil/silchashtable.[ch].
2729 * Added silc_hash_string_compare to compare two strings in the
2730 hash table. Affected file lib/silcutil/silcutil.[ch].
2732 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Added new function silc_idcache_del_by_context into the
2735 lib/silccore/idcache.[ch].
2737 * Changed the server's ID list routines to use the new ID Cache
2738 interface. Changes around the source tree.
2740 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Added silc_hash_table_del[_by_context]_ext functions in to the
2743 lib/silcutil/silchashtable.[ch].
2745 Removed silc_hash_table_find_all* routines and added new
2746 silc_hash_table_find_foreach to replace them.
2748 Added silc_hash_table_replace_ext function as extended
2749 replacing function. Separated the simple hash table interface
2750 from the extended hash table interface in the file
2751 lib/silcutil/silchashtable.h.
2753 * Fixed minor bugs and changed it to use some of the new
2754 hash table functions in lib/silccore/idcache.c
2756 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Added new function silc_hash_table_find_all to return all keys
2759 in the hash table by the specified key. As the hash table is
2760 collision resistant it also makes it possible to have several
2761 duplicate keys in the hash table. This function may be used to
2762 find all of the keys from the hash.
2764 Added user_context arguments to the SilcHashFunction,
2765 SilcHashCompare and SilcHashDestructor to deliver user specified
2768 Added new fuctions silc_hash_table_find[_all]_ext to do
2769 extended lookup with specified hash and compare functions and
2770 specified user contexts.
2772 Added new function silc_hash_table_add_ext to add the key
2773 with specified hash function and user context.
2775 Added new function silc_hash_table_foreach to traverse all
2776 entrys in the hash table. Added SilcHashForeach callback
2779 Added new function silc_hash_table_del_by_context to delete
2780 the entry only if the context associated with the key matches.
2782 Affected files are lib/silcutil/silchashtable.[ch].
2784 * Removed silc_hash_[server/client/channel]_id and added just
2785 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2786 silc_hash_id_compare to compare two ID's using as the hash table
2787 comparison function. Added also silc_hash_data to hash
2788 binary data and silc_hash_data_compare to compare it.
2790 * Removed silc_idlist_find_client_by_hash as it is not needed
2791 anymore. Affected file silcd/idlist.[ch].
2793 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2794 to use internally the SilcHashTable. The new ID Cache is a lot
2795 faster than the old one. Some of the ID Cache interface was also
2796 rewritten and obsolete and stupid functions were removed.
2798 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Added entry_count field to the SilcHashTable to keep the number
2801 of the entries in the table. Implemented the function
2802 silc_hash_table_rehash. Added new function
2803 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2805 Fixed a minor bug in silc_hash_table_free.
2807 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2808 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2809 into the lib/silcutil/silcutil.[ch].
2811 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Implemented a collision resistant hash table into the
2814 lib/silcutil/silchashtable[ch]. See the header and the source
2815 for the SilcHashTable API.
2817 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Merged dotconf version 1.0.2 into lib/dotconf.
2821 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Do not compile anything in lib/silcsim/* if the SIM support
2824 is not enabled. The tree should now compile without problems
2827 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Compiled the SILC under cygwin. Compiled and tested briefly
2830 without problems. More tests needed. The SIMs didn't compile
2833 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2835 * Fixed possible crash in silc_get_username in the
2836 lib/silcutil/silcutil.c.
2838 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Fixed a va_arg in silc/client_ops.c.
2842 * Oops, RC5 routines were named AES and caused some problems
2843 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2845 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Added new SilcIDIP structure into the lib/silccore/id.h and
2848 replaced the old `ip' fields from all SILC ID's to that type.
2849 This is a step towards IPv6 support.
2851 The silc_id_get_len takes now the ID as an extra argument.
2852 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2853 both IPv4 and IPv6 based ID's.
2855 The affected files are lib/silccore/id.[ch] and other files
2856 around the tree using these routines.
2858 * Removed the ID length arguments in server from various
2859 silc_server_send_notify_* routines -> they are not needed
2862 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Fixed memory leak in silc_encode_pem_file in the file
2865 lib/silcutil/silcutil.c.
2867 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Check minor version as well in the SKE. Affected files are
2870 silcd/protocol.c and lib/silcclient/protocol.c.
2872 * Added --identifier option to the server so that an identifier
2873 can be when creating the public key for the server. Affected
2874 file is silcd/silcd.c.
2876 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2877 lib/silccrypt/silcpkcs.c.
2879 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Register default ciphers and stuff when using -C option with
2882 the server. Affected file sildc/silcd.c.
2884 * Put back the servers public key filename format, it is better
2885 than the new one. For now, the client keys are saved with the
2886 new filename format. The affected file silc/client_ops.c.
2888 * Implemented the Cipher API for the rest of the ciphers that
2889 did not implement it or implemented it the wrong way.
2891 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Register default ciphers and stuff when using the -S option
2894 in the client. Affected file silc/silc.c. Same also when
2895 creating new key pair with -C option.
2897 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Fixed the silc_verify_public_key client operation function to
2900 save the public keys differently. The fingerprint is now
2901 used as filename and not the hostname. This way also the
2902 client keys are saved uniquely and not with hostnames. The
2903 affected file is silc/client_ops.c.
2905 * Trimmed the silc_hash_fingerprint function to remove extra
2906 whitespaces from the end of the fingerprint. The affected
2907 file is lib/silccrypt/silchash.c.
2911 * Added silc_cipher_register_default function to register all
2912 default ciphers. It can be used when configuration files
2913 does not exist and the application does not want any specific
2914 ciphers in any specific order.
2916 The SilcDList is now used as silc_cipher_list dynamically
2917 allocated cipher list. Removed the static list all together
2918 and now all ciphers must be allocated to the dynamic list.
2919 The silc_cipher_alloc routine was changed to check only the
2922 All silc_cipher_* routines that used to return int returns
2925 The affected files lib/silccrypt/silccrypt.[ch].
2927 * The same thing was done to silc_hash_* as for silc_cipher_*
2928 routines. Affected files lib/silccrypt/silchash.[ch].
2930 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2931 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2932 Added also silc_pkcs_[un]register[_default] functions.
2933 Removed the data_context from the PKCS API.
2935 * Added silc_hmac_register_default function to register default
2936 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2937 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2938 to unregister all hmacs at once.
2940 * Register the default ciphers, hash functions, PKCSs and HMACs
2941 if client's configuration file does not exist. The affected
2944 * The client did not load the hash functions from the SIM
2945 modules at all. Added support for this. Affected file is
2946 silc/clientconfig.c.
2948 * When decoding public key with silc_pkcs_public_key_decode, check
2949 the supported algorithm only if PKCS are registered. Affected
2950 file lib/silccrypt/silcpkcs.c. The same was done with the
2951 silc_pkcs_private_key_decode.
2953 * Fixed the SILC List routines to keep the list always in order.
2954 It used to change the list's order when traversing the list but
2955 not it preserves the order. Affected file lib/trq/silclist.h.
2957 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added the client library to use the SilcSocketConnection's
2960 reference counter (by silc_socket_dup) to prevent the bug that
2961 the socket object may be freed underneath async operation.
2963 * The name resolv library checking fixes in the configure.in.pre.
2966 * Created new version of the protocol drafts for future
2967 development. The -03 drafts are the ones that will be changed
2968 in the trunk now and the -02 will remain as they are.
2970 * Send list of CUMODE notifys to the router when announcing
2971 the channel users to the router. Affected file silcd/server.c.
2972 If the router receiving channel founder CUMODE for a channel
2973 that already has channel founder it will send CUMODE notify
2974 to the sender to remove the channel founder rights from the
2975 announced client. Affected file silcd/packet_receive.c.
2977 * The CUMODE notify may now use Server ID as well as the entity
2978 who changes the mode. Updated protocool specs.
2980 * Updated INSTALL and README files.
2982 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * New web pages in the http://silc.pspt.fi. The pages was
2989 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Implemented the [DenyConnectin] config section in the server.
2992 Added silc_server_config_denied_conn to check whether incoming
2993 connection is denied. Affected file silcd/serverconfig.[ch].
2995 * Do not check the ports when checking the incoming configuration
2996 data if the port is 0, meaning any. Affected file is
2997 silcd/serverconfig.c.
2999 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Fixed buffer overflow in silc_string_compare in the file
3002 lib/silcutil/silcutil.c.
3004 * Fixed double free in silc_server_command_leave in the file
3007 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3009 * Fixed the version checking in the server. Affected file is
3012 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Fixed the configuration data fetching when accepting new
3015 connections in the server. Affected file silcd/server.c.
3017 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Added `sender_entry' argument to the function
3020 silc_server_packet_relay_to_channel so that we can check
3021 whether some destination actually belongs to the same route
3022 the sender belongs (ie, we must not resend the packet to the
3023 sender). Affected file silcd/packet_send.[ch].
3025 * Added `servername' field to the SilcClientEntry in the server
3026 to hold the name of the server where client is from. Affected
3027 file is silcd/idlist.h.
3029 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Moved the channel message encrypting in the router betwen
3032 router connections from silc_server_channel_message to the
3033 silc_server_packet_relay_to_channel since we want to check
3034 whether we have anybody channel before encrypting anything.
3035 Affected files silcd/packet_[receive/send].c.
3037 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Fixed the [AdminConnection] server config section to support
3040 multiple entries. Affected file silcd/serverconfig.c.
3042 * Added support into the server to check the validity of the
3043 incoming connection before executing any KE or authentication
3046 * The connection configuration is now saved to the KE and
3047 connection auth protocol contexts and not fetched anymore in
3048 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3050 * The local hosts listenning address and port is also resolved
3051 now when starting the server. We want to have the socket object
3052 to include the real address and port for the listener. Added
3053 new function silc_net_check_local_by_sock into the files
3054 lib/silcutil/silcnet.[ch].
3056 * Fixed a broadcast bug in server -> do not broadcast if we
3059 * Fixed a routing bug. Do not route broadcast packets ever.
3060 Broadcast packets must be processed always and not routed since
3061 they may be destined to some other host than yourself and thus
3062 would get routed without no good reason. Affected file is
3065 * Added function silc_server_config_is_primary_route to check
3066 whether primary router connection has been configured (a router
3067 configuration that we are initiating). If there is not, we
3068 will assume that there is only two routers in the SILC network
3069 and we will use the incoming router connection as our primary
3070 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3072 * Changed the order of the broadcasting. Broadcast _after_ the
3073 packet has been processed not before. Affected file is
3076 * Fixed a [ClientConnection] parsing bug. The port was never
3077 parsed correctly thus resulting to port 0. Affected file
3078 silcd/serverconfig.c.
3080 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3081 argument and did not set the broadcast packet flag. Affected
3082 file silcd/packet_send.c. Fixed same bug in the function
3083 silc_server_send_notify as well.
3085 * If we receive NEW_ID packet for our own ID in the server, ignore
3088 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Removed the nickname from the Private Message Payload.
3093 Updated the code and the protocol specs.
3095 * Updated protocol specs for submitting to the IETF.
3097 * Tweaked the Random Number Generator a bit. Affected file
3098 lib/silccrypt/silcrng.c. Exported a new function
3099 silc_rng_[global]_add_noise which can be used to add more
3102 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Do not parse packets with different timeout when protocol
3105 is active -> may cause problem with rekey. Affected file
3108 * When server receives signoff notify it must not create
3109 new channel key if the client is on any channels since the
3110 sender of the signoff notify will create it.
3112 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Added printing of error messages during SKE protocol from the
3115 failure packet sent by server during SKE. Affected file
3118 * Removed the client's failure_callback handling with timeout
3119 and handle it immediately when received.
3121 * The SKE library returned wrong type in SUCCESS and FAILURE
3122 packets. They must be 32 bit MSB not 16 bit MSB.
3124 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Ok, rewrote the logic of the re-key and now it seems to work.
3127 I tested it on high traffic with frequent re-keys without
3128 problems. Added hmac_receive (and renamed hmac to hmac_send)
3129 in SilcClientConnection in lib/silcclient/client.h and
3130 in SilcIDListData in silcd/idlist.h. Also, removed the
3131 SilcPacketParserContext's cipher and hmac fields as they are
3132 not needed anymore and actually caused some problems when
3133 the ciphers and hmac's changed underneath the packet parser.
3135 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * If re-key protocol is active then process the incoming packets
3138 synchronously since we must assure that icoming packets encrypted
3139 with the old key is processed before the new keys is set to
3140 use. This is true other packets than for REKEY packets.
3141 Affected file silcd/server.c. The same was done to client library
3142 as well, affected file lib/silcclient/client.c.
3144 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Fixed bug in client and server to accept the force send if
3147 the packet is send from silc_[server/client]_packet_process
3148 function. Otherwise the packets are never delivered, oops.
3150 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Disable force sending of packets when REKEY protocol is active.
3153 We must assure that no packet is sent directly when rekey is
3154 performed. All packets must be sent through packet queue.
3155 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3156 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3157 function is silc_[server/client]_packet_send_real to check
3160 * Replaced the SIM paths from example config files to
3161 /usr/local/modules. Also, make install creates now
3162 /usr/local/silc/logs directory to hold all the SILC server
3165 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Made the configure.in.pre work on Solaris. Patch by salo.
3169 * Made all ciphers compatible with non-x86 machines. Defined
3170 CBC mode macros into lib/silccrypt/ciphers_def.h.
3172 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Fixed the make install.
3176 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * When MAC computation fails the silc_packet_decrypt returned 0
3179 even though it was supposed to return -1. Fixed this. The
3180 affected file is lib/silccore/silcpacket.c.
3182 * Do not replace the config files in /etc/silc (in make install)
3183 if they already exist. Affected file ./Makefile.am.
3185 * Do not send re-key packets immediately but through packet queue.
3186 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3188 * Changed silc_net_check_host_by_sock to return FALSE if the
3189 IP/DNS could not be resolved. Though, it returns the IP address
3190 now even if it could not resolve it (but returns also FALSE).
3191 Affected file lib/silcutil/silcnet.[ch].
3193 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Added silc_pkcs_decode_identifier to decode the public key's
3196 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3197 Added also silc_pkcs_free_identifier. Added also new context
3198 SilcPublicKeyIdentifier.
3200 * Added -S option to the silc client. It is used to dump the
3201 contents of the specified public key file.
3203 * Changed the PKCS api to return the public key length when
3204 setting the public key.
3206 * Fixed a fatal bug in the public and private key file loading.
3207 Affected file lib/silccrypt/silcpkcs.c.
3209 * Execute the packet parsing for client with zero (0) timeout
3210 if the protocol is active. Affected file silcd/server.c.
3212 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Made the key generation options to the silcd program. Added
3215 -C option, equivalent to client's option.
3217 * Added new [ServerKeys] config section to the server. It
3218 configures the server's public and private key.
3220 * Defined generic Public Key Payload into the protocol
3221 specification to send specific type of public keys and
3224 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3225 public key or certificate.
3227 * Implemented the GETKEY command to the server and to the
3228 client library and on user interface.
3230 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Made preliminary `make install' work.
3234 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Added SilcServerRekey context into silcd/idlist.h.
3238 * Added the PFS support as defined in the specification to the
3239 SKE protocol. Affected files lib/silcske/*.c.
3241 * Added `ske_group' field to the SilcServerRekey context to hold
3242 the number of the SKE group that is used with PFS in re-key.
3243 Affected file silcd/idlist.h.
3245 * Added PFS re-key support to the server. Affected file is
3248 * Added silc_protocol_cancel to cancel execution of the next
3249 state of the protocol. Affected file is
3250 lib/silccore/silcprotocol.[ch].
3252 * Added the re-key support with and without PFS to the client
3253 library. Re-key is performed once in an hour, by default.
3255 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3256 Added silc_client_rekey_callback and silc_client_rekey_final.
3257 Affected files are lib/silcclient/protocol.[ch] and
3258 lib/silcclient/client.[ch].
3260 * Removed the `hmac_key' and `hmac_key_len' fields from the
3261 SilcClientConnection structure; not needed. Affected file is
3262 lib/silcclient/client.h.
3266 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Do not ask whether user wants to use the negotiated private key
3269 for private messages, just use it. Affected file is
3270 silc/local_command.c.
3272 * Added `send_enc_key' and `enc_key_len' fields to the
3273 SilcIDListData structure since they are needed in the re-key
3274 phase. Affected file is silcd/idlist.[ch].
3276 * Implemented the simple re-key protocol into the server.
3277 Affected files silcd/server.c and silcd/protocol.[ch]. The
3278 re-key will be performed once in an hour, by default.
3280 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3281 Added silc_server_rekey, silc_server_rekey_callback and
3282 silc_server_rekey_final.
3284 * Removed Tunneled flag from the protocol. Updated the code
3285 and the specifications.
3287 * Adde `pfs' field to the SilcIDListData to indicate whether
3288 the PFS is to be performed in the re-key. Affected file is
3291 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3294 int64 of at least the xintXX size. If void * is less that 4
3295 bytes uint32 * will be used. Defined bool as boolean.
3297 * Changed _ALL_ unsigned long and unsigned int to uint32,
3298 unsgined short to uint16 in the source tree.
3300 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3301 not handle clients that has entry->data.registered == FALSE.
3302 They are not in the network anymore. Affected file is
3305 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Implemented the sending of the SERVER_SIGNOFF notify in the
3308 server. Affected file is silcd/server.c.
3310 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3311 Added also silc_notify_payload_encode_args into the
3312 lib/silccore/silcnotify.[ch].
3314 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3315 Affected file silcd/packet_receive.c.
3317 * Implemented the SERVER_SIGNOFF notify handling in the client
3318 library. Affected file lib/silcclient/client_notify.c. Also,
3319 implemnted the printing of the SERVER_SIGNOFF info to the
3320 application. Affected file silc/client_ops.c.
3322 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3323 if the deleting was successful. Affected file silcd/idlist.[ch].
3325 * Added support for public key authentication in the connection
3326 authentication protocol in the client library. Affected file
3327 lib/silcclient/protocol.c.
3329 * Changed the server's silc_idlist_get_clients_by_* interface
3330 to support already allocated array so that new entries may be
3331 added to pre-allocated array. Affected file silcd/idlist.[ch].
3332 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3333 and command replies.
3335 * All command reply functions in the server now calls the
3336 pending command callback even if error occured. This way the
3337 error will be delivered to the client as well. Affected files
3338 silcd/command.c and silcd/command_reply.c.
3340 * Fixed INFO command to return local server's info if no server
3341 was provided. Affected file lib/silcclient/command.c.
3343 * Removed RESTART command for good. Updated the code and the
3346 * Rewrote parts of the task system. It is a bit simpler now.
3347 Removed unsued task priorities. The affected files are
3348 lib/silcutil/silctask.[ch].
3350 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Moved the USERS printing from the library to the application.
3353 Affected files lib/silcclient/command.c and silc/client_ops.c.
3355 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added channel key re-key support. The re-key is perfomed
3360 only by the router and is done once in an hour. Added `rekey'
3361 field to the SilcChannelEntry in the server. Affected files
3362 silcd/server.c and silcd/idlist.h.
3364 * Added silc_task_unregister_by_context into the file
3365 lib/silcutil/silctask.[ch].
3367 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Added SILC_UMODE_GONE mode to indicate when the client is not
3370 present in the SILC network. Added also support to the local
3371 command AWAY that will set this mode. Added support of showing
3372 "xxx is gone" in WHOIS command. The USERS command shows the
3373 gone status as well.
3375 * Fixed setting server and router operator privileges in the
3376 server's UMODE command. Affected file silcd/command.c.
3378 * Merged the SKE KE1 and KE2 payloads into one payload. The
3379 new KE payload is equivalent to the old KE2 payload.
3381 Cleaned up the SKE Start Payload parsing. It now uses the
3382 simple buffer unformatting to do the parsing. A lot faster
3385 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3386 to the SKE that is used to indicate whether both of the SKE
3387 parties should perform authentication. By default only the
3388 responder performs authentication. By setting this flag also
3389 the initiator must do authentication. By default it is unset
3390 since in normal SKE case, client to server connection, only
3391 the responder should do authentication. When doing SKE between
3392 two clients both should perform authentication. Updated the
3393 code and the protocol specs.
3395 * A little fix to IDENTIFY command in the server. Search the
3396 client first by hash not nickname. Affected file is
3399 * Fixed the silc_client_close_connection to support closing
3400 the client to client connections wihtout deleting too much
3401 data. Affected file lib/silcclient/client.c.
3403 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3404 are received if protocol used to be active but is not anymore
3405 the application would crash due to NULL pointer dereference.
3406 Affected files silcd/server.c and lib/silcclient/client.c.
3408 * Added `hash' field to the SilcClientConnection to include
3409 the hash function negotiated in the SKE protocol.
3411 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3412 to set the channel founder authentication data. A client can
3413 claim the founder rights later by providing the authentication
3414 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3415 This way the channel founder can regain the channel founder
3416 privileges even it is left the channel. This works only on
3417 local server and the client must be connected to the same
3418 server to be able to regain the founder rights. Updated the
3419 protocol specs accordingly.
3421 Added support to the CMODE command in the client to set the
3422 founder auth data. Read the README to see how to set it.
3424 Added support to the CUMODE command to claim the founder
3425 rights. Read the README to see how to do it.
3427 Added support for the founder authentication to the Channel
3428 Entry in the server. Affected file silcd/idlist.h.
3430 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3431 server's CMODE command. Affected file silcd/command.c.
3433 * Added the following new functions into lib/silccore/silcauth.[ch]:
3434 silc_auth_get_method and silc_auth_get_data.
3436 * The server now saves the remote hosts public key to the
3437 SilcIDListData pointer. Affected file silcd/protocol.c.
3439 * The normal server now does not remove the channel entry from
3440 the cache if the founder authentication data is set. It used
3441 to remove it if the founder was the last one on the channel on
3442 the server and left the channel. The auth data is saved and
3443 if the channel is re-joined later the old entry is used with
3444 the old auth data. Affected files silcd/command_reply.c and
3447 * Removed the `pkcs' field from the SilcIDListData structure
3448 in the server; it is not used. Affected file silcd/idlist.h.
3450 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Fixed packet processing on slow links. Partial packets were
3453 never re-processed because the incoming data buffer was cleared
3454 by the application. Application must not directly clear the
3455 sock->inbuf, the packet processing routines handle it. Fixed
3456 this in client library and in server.
3458 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Fixed the WHOIS and IDENTIFY send reply function to really
3461 check whether to send list or just one entry. Affected file
3464 * Cleaned up the LEAVE command's channel key distribution. The
3465 affected file silcd/command.c.
3467 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3468 can enforce the channel mode as well. In that case the ID
3469 includes the ID of the server. The code now enforces the
3470 mode change if the router have different mode than the server.
3472 * The notify client operation with CMODE_CHANGE notify can now
3473 return NULL client_entry pointer if the CMODE was not changed
3474 by client. Application must check for this.
3476 * Added <Server ID> argument to INFO command to support server
3477 info fetching by Server ID.
3479 * Added silc_server_announce_get_channel_users to get assembled
3480 packets of channel users of the specified channel. Affected
3481 file silcd/server.[ch].
3483 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3484 was freed underneath the ID Cache.
3486 * Re-announce clients when the server received CHANNEL_CHANGE
3487 notify from the router. Affected file silcd/packet_send.c.
3489 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3492 crashed since it did not handle the fact that there is no cipher
3493 called "3" and didn't check the error condition. Now fixed.
3495 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3496 flag. It can be used to send message requests.
3498 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Implemented the RESTART command in the client.
3502 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3503 notice type messages. Added notice printing to the user
3506 * The channel keys are not re-generated if the channel's mode
3507 is PRIVKEY, ie private key on the channel exists. Affected
3508 files silcd/server.c and silcd/command.c.
3510 * Fixed a little bug in channel message delivery when channel
3511 private keys are set in the server. Affected file is
3512 silcd/packet_send.c.
3514 * Changed the setting on channel->on_channel = TRUE from the
3515 silc_client_save_channel_key to the JOIN command reply. The
3516 key payload is not received if the private channel key is set.
3517 Affected file lib/silcclient/command_reply.c and the
3518 lib/silcclient/client_channel.c.
3520 * When the CMODE_CHANGE notify is sent and the channel private
3521 key mode is removed the channel key must be re-generated in
3522 other cells as well. Added this support for the router in the
3523 silcd/packet_receive.c.
3525 * Added new local command NOTICE to send notice message on
3526 channel. Affected file silc/local_command.[ch].
3528 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Added new local command ME to the client. It is used to send
3531 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3532 some action. Affected file silc/local_command.[ch].
3534 * Changed channel_message and private_message client operations
3535 to deliver the message flags to the application. Added also
3536 the `flags' arguments to the silc_client_send_channel_message
3537 and silc_client_send_private_message functions. Affected file
3540 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Redefined the Private Message Payload to support private message
3543 keys and to support the new private message flags. Updated
3544 the protocol specs. Flags makes it possible to have for example
3545 CTCP style messages.
3547 * Added new type SilcPrivateMessagePayload and defined an API
3548 for it in the lib/silcclient/silcprivate.[ch].
3550 * Tested private message private keys successfully. Tested the
3551 private message key set, unset and list commands with the new
3554 * Redefined the Channel Message Payload to include the channel
3555 message flags (equal with private message flags) to support
3556 for example CTCP style messages.
3558 * Defined some of the message (for channel and private message)
3559 flags. Updated the protocol specs and added the flags to the
3560 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3562 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Added SilcKeyAgreementStatus type to the key agreement routines
3565 to indicate the current status and error if one occured.
3566 The status types are defined in the lib/silcclient/silcapi.h.
3568 * Added new local command KEY that is used to set and unset private
3569 keys for channels, set and unset private keys for private messages
3570 with remote clients and to send key agreement requests and
3571 negotiate the key agreement protocol with remote client. The
3572 key agreement is supported only to negotiate private message keys,
3573 it currently cannot be used to negotiate private keys for channels,
3574 as it is not convenient for that purpose.
3576 * Fixed a minor pending callback setting bug in the function
3577 silc_client_get_client_by_id_resolve, now the function works.
3578 Affected file lib/silcclient/idlist.c.
3580 * Added function silc_net_get_local_port to get local bound
3581 port by socket. Added to lib/silcutil/silcnet.[ch].
3583 * Added `sockets' and `sockets_count' fields to the SilcClient
3584 object. They hold the sockets of the listenning sockets in
3585 the client. Listenning sockets may be for example the key
3586 agreement server. Affected file lib/silcclient/client.[ch].
3587 Added functions the silc_client_add_socket and the
3588 silc_client_del_socket. They are exported to the application
3591 * Added ~./silc/clientkeys to support other client's public keys.
3593 * Renamed verify_server_key client operation to verify_public_key
3594 and added one argument to indicate the type of the connection
3595 (server, client etc.).
3597 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Added silc_server_connection_auth_request to handle the
3600 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3601 silcd/packet_receive.[ch].
3603 * Added silc_server_send_connection_auth_request into the
3604 silcd/packet_send.c to send the connection auth request packet.
3606 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3609 * Fixed the public key authentication in responder side in the
3610 server. The `auth_data' pointer includes the SilcPublicKey
3611 not the path to the public key. Affected file silcd/protocol.c.
3613 * Implemented the public key authentication in the initiator side
3614 in the server. Affected file silcd/protocol.c.
3616 * Removed the [RedirectClient] config section from the server
3617 configuration. Is not needed and I don't want to implement it.
3619 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Cleaned up the CMODE command in the server. It now works
3622 correctly and supports all the modes defined in the protocol.
3623 Affected file is silcd/command.c.
3625 * Added `hmac_name' field to the SilcChannelEntry in the server
3626 to hold the default HMAC of the channel. It can be set when
3627 creating the channel (with JOIN command). Affected files
3630 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3631 type to indicate the change of the current cipher and hmac
3632 on the channel. Client can safely ignore the <cipher> argument
3633 (if it chooses to do so) since the CHANNEL_KEY packet will
3634 force the channel key change anyway. The <hmac> argument is
3635 important since the client is responsible of setting the new
3636 HMAC and the hmac key into use.
3638 * Fixed the CMODE command in the client library as well.
3640 * Tested CMODE command in router environment successfully.
3642 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Show the version of the remote client (or server) when connecting
3645 to the server. It is logged to the log file. Affected file
3646 is silcd/protocol.c.
3648 * Fixed the KILLED notify handling in the client library. The
3649 client must be removed from all channels when receiving the
3652 Also, do not remove the client entry when giving the KILL
3653 command but when the KILLED notify is received.
3655 * Removed silc_idlist_find_client_by_nickname from the server.
3656 Not needed anymore. Affected files silcd/idlist.[ch].
3658 * Implemented the CHANNEL_CHANGE notify type handling to the
3659 server. Affected file silcd/server.c.
3663 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added silc_server_send_notify_invite to send the INVITE
3666 notify between routers.
3668 * Implemented the INVITE command correctly to the server.
3670 * Implemented the INVITE notify type handling in the server.
3672 * Implemented the INVITE command to the client library and on the
3675 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Added function silc_server_get_client_resolve to find the
3678 client entry by ID from all ID lists and then resolve it
3679 (using WHOIS) if it cannot be found. Affected file is
3682 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Implemented the BAN command to the client library.
3686 * The JOIN command in the server now checks the invite list
3689 * Changed the silc_command_reply_payload_encode_va and the
3690 silc_command_payload_encode_va to support that if argument is
3691 NULL it ignores and checks the next argument. Affected file
3692 lib/silccore/silccommand.c.
3694 * Added silc_server_send_notify_ban to send the BAN notify
3695 type between routers.
3697 * Chaned the silc_notify_payload_encode to support that if
3698 argument is NULL it ignores and checks the next argument.
3699 Affected file lib/silccore/silcnotify.c.
3701 * Tested ban lists in router environment successfully.
3703 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Implemented BAN command to the server, in silcd/command.[ch].
3707 * Removed the BAN and INVITE_LIST modes from the CMODE command
3710 * Added function silc_string_match to regex match two strings.
3711 Affected files lib/silcutil/silcutil.[ch].
3713 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Redefined parts of the SilcChannelEntry in the server to support
3716 the new ban and invite lists.
3718 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Redefined the INVITE command. The same command can be used to
3721 invite individuals to the channel but also to manage the invite
3722 list of the channel (to add to and remove from the invite list).
3723 Updated the protocol specs.
3725 * Added new command SILC_COMMAND_BAN that can be used to manage
3726 the ban list of the channel. Updated the protocol specs.
3728 * Removed the channel modes: the SILC_CMODE_BAN and the
3729 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3730 in the CMODE command. The equivalent features are now available
3731 using INVITE and BAN commands. Updated the protocol specs.
3733 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3734 in the network about change in the current ban list. The notify
3735 type is not used by the client.
3737 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3738 support the invite lists.
3740 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Added new function silc_string_regexify that converts string
3743 including wildcard characters into regex string that can
3744 be used by the GNU regex library. Added into the file
3745 lib/silcutil/silcutil.[ch].
3747 Added silc_string_regex_combine to combine to regex strings
3748 into one so that they can be used as one regex string by
3749 the GNU regex library. Added into the file
3750 lib/silcutil/silcutil.[ch].
3752 Added silc_string_regex_match to match two strings. It returns
3753 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3755 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Imported GNU regex to the soruce tree into lib/contrib.
3758 Fixed some compiler warning from the regex.c.
3760 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Fixed MOTD command in the server to work in router environment.
3764 * Fixed the MOTD command in the client library to support
3765 the server argument in the command.
3767 * Added `nickname_len' argument to the silc_idlist_add_client
3768 in the server, as the `nickname' argument may be binary data
3771 * Added silc_idlist_get_channels to return all channels from
3774 * Implemented LIST command to the server. Affected file is
3777 * Implemented the LIST command to the client library and on the
3780 * Added [<user count>] argument to the LIST command reply.
3781 With private channels the user count is not shown.
3783 * Updated TODO and README.
3785 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * The client entry's data.registered must be TRUE even with
3788 global client entry on global client list. The data.registered
3789 is used to check whether the client is anymore in the network,
3790 for example with WHOWAS command so it must be valid.
3792 * Fixed the WHOWAS command in the server. It now actually works
3793 in router environment. Added function into silcd/command_reply.c
3794 silc_server_command_reply_whowas_save.
3796 * Added silc_idlist_purge function to the silcd/idlist.c
3797 to periodically purge the ID Cache.
3799 * Fixed INFO command in the server. It works now in router
3800 environment. Added <server name> argument to the INFO command
3801 reply. Updated the protocol specs.
3803 * Fixed minor bug in silc_idcache_purge to not purge if the
3804 expire value is zero.
3806 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3807 they were buggy because of the WHOWAS information.
3809 * Fixed local command MSG to handle the async resolving of
3810 the remote client properly. It used to fail the first MSG.
3811 Affected file silc/local_command.c.
3813 * Added `data_len' field to SilcIDCache context.
3815 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Update TODO. Todo in commands in the server.
3819 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3822 used by routers as broadcast packet to inform other routers
3823 about the changed user mode.
3825 Implemented the notify handling in the server. Affected file is
3826 silcd/packet_receive.c. Added the function
3827 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3829 * Added new generic Channel Payload and deprecated the New Channel
3830 Payload. The New Channel Payload is now the generic Channel
3833 * Added new argument `mode' to the silc_server_send_new_channel
3834 as it is required in the Channel Payload now.
3836 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3837 and created a new and real SilChannelPayload to represent the
3838 new generic Channel Payload. Implemented the encode/decode
3839 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3841 * Added silc_server_get_client_channel_list to return the list
3842 of channels the client has joined for WHOIS command reply.
3843 Affected file silcd/server.[ch].
3845 * Implemented the channel list sending in the WHOIS command reply
3846 in server and in the client.
3848 Implemented the channel list displaying on the user interface
3849 as well. Affected file silc/client_ops.c.
3851 * Added silc_channel_payload_parse_list to parse list of Channel
3852 Payloads. It returns SilcDList list of SilcChannelPayloads.
3853 Client for example can use this function to parse the list of
3854 channels it receives in the WHOIS command reply. The caller
3855 must free the list by calling silc_channel_payload_list_free.
3856 Affected files lib/silccore/silcchannel.[ch].
3858 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added one new argument <user mode> to the WHOIS command reply
3861 to return the mode of the user in SILC. Updated the protocol
3864 Implemented it to the server and client.
3866 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Fixed the mode printing on the user interface on joining.
3869 Affected file silc/client_ops.c.
3871 * Implemented the UMODE command and user modes in general to the
3872 client library and to the user interface.
3874 * Implemented the UMODE command to the server.
3876 * The server now sends UNKNOWN_COMMAND error status if client sends
3877 unknown command. Affected file silcd/command.c.
3879 * All server commands now handle the command identifier the right
3880 way when sending the command reply to the client. The client can
3881 use to identify the command replies with the identifier.
3883 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Added silc_server_get_client_route to resolve the route to
3886 the client indicated by the client ID. Affected file is
3889 * Added silc_server_relay_packet as general function to relay
3890 packet to arbitrary destination. This deprecates functions
3891 like _send_private_message_key, _relay_notify etc. Affected
3892 file is silcd/packet_send.[ch].
3894 Removed silc_server_send_key_agreement,
3895 silc_server_send_private_message_key and
3896 silc_server_packet_relay_notify functions from the file
3897 silcd/packet_send.[ch].
3901 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3902 server. Affected file silcd/packet_receive.[ch].
3904 * Implemented the KILL command to the client. Implemented the
3905 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3906 Affected files lib/silcclient/command[_reply].c and
3907 lib/silcclient/client_notify.c. Implemented the KILL notify
3908 printing in the user inteface.
3910 * Fixed a lot silc_parse_nick memory leaks from the client
3911 library in the file lib/silcclient/command.c.
3913 * Changed the silc_server_send_notify_on_channels's `sender'
3914 argument from SilcSocketConnection to SilcClientEntry to
3915 check the sender as entry and not as connection object and not
3916 to send to the client provided as argument. The affected file
3917 is silcd/packet_send.[ch].
3919 * The notify packets that are destined directly to the client used
3920 to not to be processed by the server. Now changed that and the
3921 server processes all notify packets. After relaying the packet
3922 to the client the notify packet is processed in the server.
3924 * The silc_server_free_client_data now checks whether there is
3925 pending outgoing traffic for the client and purges the data to
3926 the network before removing the client entry.
3928 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3931 an client is killed from the SILC Network. Updated the protocol
3934 Added new function silc_server_send_notify_killed to the
3935 silcd/packet_send.[ch].
3937 * Added function silc_server_packet_relay_notify to relay notify
3938 packets that are destined directly to a client. In this case
3939 the server does not process the notify packets but merely relays
3940 it to the client. Affected file silcd/packet_send.[ch].
3942 Added also silc_server_packet_process_relay_notify to check
3943 whereto relay the notify. Affected file is
3944 silcd/packet_receive.[ch].
3946 * Implemented the KILL command to the server.
3950 * Added the backup schema desgined last fall to the protocol
3951 specs for everyone to see. The specification is in the
3952 *-spec-xx.txt draft and the packet type definitions for the
3953 backup routers is in *-pp-xx.txt draft. Thusly, added also
3954 new packet type SILC_PACKET_CELL_ROUTERS.
3956 * A big security problem in the implementation discovered. The
3957 signoff of an client did not cause new channel key generation
3958 which it of course should've done. The channel keys must be
3959 always re-generated when client leaves (or signoffs) the channel.
3960 The silc_server_remove_from_channels funtion now handles
3961 the channel key re-generation.
3963 * Added `sender' argument to the silc_server_send_notify_on_channels
3964 to not to send the client provided as argument. Affected file
3965 silcd/packet_send.[ch].
3967 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Implemented OPER and SILCOPER commands into the server and
3972 * Added silc_auth_verify and silc_auth_verify_data to verify
3973 the authentication directly from the authentication payload.
3974 It supports verifying both passphrase and public key based
3975 authentication. Affected file lib/silccore/silcauth.[ch].
3977 * Added `hash' field to the SilcIDListData structure. It is the
3978 hash negotiated in the SKE protocol. Affected file is
3981 * Slight redesigning of the SilcAuthPayload handling routines.
3982 Do not send SilcPKCS but SilcPublicKey as argument.
3984 * Implemented the public key authentication support to the
3985 serverconfig. The public key is loaded from the provided path
3986 and saved as authentication data to void * pointer. Thus,
3987 changed the unsigned char *auth_data to void *auth_data;
3989 * Fixed SHUTDOWN command to send the reply before the server
3990 is shutdown. :) Affected file silcd/command.c.
3992 * Fixed fatal bug in CONNECT command. The hostname was invalid
3993 memory and server crashed. Affected file silcd/command.c.
3995 * Fixed fatal bug in CLOSE command. The server_entry became
3996 invalid but was referenced later in the command. Affected file
3999 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed fatal bug in failure packet handling. Server ignored
4002 the failure and thus crashed when it came.
4006 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4009 that the command may be executed only once in (about) 2 seconds.
4010 The old SILC_CF_LAG flag is same but allows command bursts up
4011 to five before limiting.
4013 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4014 server code. Various commands now includes the CF_LAG_STRICT
4015 flag to disallow any kind of miss-use of the command.
4017 * Fixed the silc_buffer_unformat to not to allocate any data
4018 if the length of the data is zero. It used to allocate the
4019 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4021 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Changed the format of AdminConnection configuration section
4024 in the server. Added username of the admin to the format.
4025 Affected files silcd/serverconfig.[ch].
4027 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4028 to return admin configuration data by host, username and/or
4031 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Implemented WHOWAS command to the server. Added the functions:
4035 silc_server_command_whowas_parse,
4036 silc_server_command_whowas_send_reply,
4037 silc_server_command_whowas_from_client and
4038 silc_server_command_whowas_from_server
4040 * Added <Client ID> argument to the WHOWAS command reply. Updated
4041 the protocol specs accordingly.
4043 * Implemented WHOWAS command and command_reply to the client
4046 Implemented the WHOWAS printing on the user interface.
4048 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Added new argument to the WHOWAS command reply, the real name.
4051 It is an optional argument. Updated the protocol specs.
4053 * Added SilcIDCacheDestructor callback that is registered when
4054 the SilcIDCache is allocated. The callback is called when
4055 an cache entry in the ID Cache expires, or is purged from the
4056 cache. Added into lib/silccore/idcache.[ch].
4058 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4059 to destruct the client entries when the cache entry expires.
4060 Other ID Cache's in server and in the client library ignores
4063 * If the ID Cache entry's `expire' field is zero then the entry
4064 never expires. Added boolean `expire' argument to the
4065 silc_idcache_add function in the lib/silccore/idcache.[ch].
4066 If it is TRUE the default expiry value is used.
4068 * Added silc_server_free_client_data_timeout that is registered
4069 when client disconnects. By default for 5 minutes we preserve
4070 the client entry for history - for WHOWAS command.
4072 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Added support to the server to enforce that commands are not
4075 executed more than once in 2 seconds. If server receives
4076 commands from client more frequently, timeout is registered
4077 to process the commands. Affected file silcd/command.c.
4078 Added new function silc_server_command_process_timeout.
4080 * Changed NICK_NOTIFY handling in client library to check that
4081 if the client's nickname was changed, so there is no need to
4082 resolve anything from the server.
4084 * Removed error printing from the WHOIS and IDENTIFY commands.
4085 If error occurs then it is ignored silently in the client library.
4086 The application, however, may map the received error to
4087 human readable error string. The application currently maps
4088 the NO_SUCH_NICKNAME error to string.
4090 * Made the command status message public to the application. Moved
4091 them from lib/silcclient/command_reply.c to
4092 lib/silcclient/command_reply.h. The application can map the
4093 received command status to the string with the
4094 silc_client_command_status_message function.
4096 * Added check to the server to check that client's ID is same
4097 as the Source ID in the packet the client sent. They must
4100 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Added dist-bzip hook to the Makefile.am to make bzip2
4103 compressed distributions.
4105 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Server now enforces the maximum length for the nickname and
4108 the channel as protocol specification dictates. 128 bytes for
4109 nickname and 256 bytes for channel name.
4111 * Moved the WHOIS printing to the application. The client libary
4112 does not print out the WHOIS information anymore, the application
4113 must do it. Renamed silc_client_command_reply_whois_print to
4114 the silc_client_command_reply_whois_save.
4116 The client's idle time is also sent to the application now, and
4117 the idle is shown on screen.
4119 * Added silc_client_command_reply_identify_save to save the
4120 received IDENTIFY entries.
4122 * Do not check for channel private keys in message sending and
4123 reception if the channel does not have the PRIVKEY mode set.
4124 Affected file lib/silclient/client_channel.c.
4126 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4129 just surfaced after chaning the JOIN procedure.
4131 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Added silc_client_get_clients_by_list to get client entries
4134 from Client ID list, that is returned for example by JOIN
4135 and USERS command replies. The application should use this
4136 function for example when JOIN command reply is received to
4137 resolve the clients already on the channel (library does not
4138 do that anymore as USERS command reply is not used in the JOIN
4139 procedure anymore). Affected files lib/silcclient/silcapi.h and
4140 lib/silcclient/idlist.c.
4142 * JOIN command reply and USERS command reply returns now SilcBuffer
4143 pointers instead of unsigned char pointers when returning
4144 the client list and mode list.
4146 * Added <Client ID> argument to the JOIN command reply, mainly
4147 for the server to identify for which client the command was
4148 originally sent. Updated protocol specs accordingly.
4150 * Added SilcDlist private_key pointer to the SilcChannelEntry
4151 in the client to support the channel private keys. Affected
4152 file is lib/silcclient/idlist.h.
4154 * Added SilcChannelPrivateKey argument to the function
4155 silc_client_send_channel_message so that application can choose
4156 to use specific private ke if it wants to. If it is not provided,
4157 the normal channel key is used, unless private keys are set.
4158 In this case the first (key that was added first) is used
4159 as the encryption key.
4161 * Implemented the support for channel private key handling.
4162 Implemented the following functions:
4164 silc_client_add_channel_private_key,
4165 silc_client_del_channel_private_keys,
4166 silc_client_del_channel_private_key,
4167 silc_client_list_channel_private_keys and
4168 silc_client_free_channel_private_keys
4170 Affected file lib/silcclient/client_channel.c.
4172 * Added the support for the private keys in the channel message
4173 sending and encryption and in the message reception and
4174 decryption. Affected funtions are
4175 silc_client_send_channel_message and silc_client_channel_message.
4177 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Added SKE's key verify callback to the client library's
4180 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4182 * Removed the statement that server (or router) must send USERS
4183 command reply when joining to the channel so that the client
4184 knows who are on the channel. Instead, the client list and
4185 client's mode list is now sent in the JOIN command reply to the
4186 client who joined channel. This is better solution.
4188 * Added function silc_server_get_users_on_channel and function
4189 silc_server_save_users_on_channel to the silcd/server.[ch].
4191 * Removed function silc_server_command_send_users from the
4194 * Do not show topic on the client library anymore. The topic is
4195 sent in the command reply notify to the application and the
4196 application must show the topic now.
4198 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Added client searching by nickname hash into the IDENTIFY and
4201 WHOIS commands in the server as they were clearly missing from
4202 them. Affected file is silcd/command.c.
4204 * Fixed a bug in private message receiving in the client library.
4205 The remote ID was freed and it wasn't supposed, now it is
4208 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Minor fix to the channel payload; allocate the data area, as it
4211 needs to be of specific length.
4213 * If the key agreement port is zero then the operating
4214 system will define the bound port. Affected files are
4215 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4217 * Added new function silc_channel_payload_decrypt into the file
4218 lib/silccore/silcchannel.[ch].
4220 * Moved the channel message etc, check from silc_packet_decrypt
4221 to applications. The library calls now a generic
4222 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4223 when the packet is either normal or special. This was done to
4224 allow more wide range of checking that was not allowed when
4225 the code was in library. Now applications can do virtually any
4226 checks to the packet and return to the library the decision how
4227 the packet should be processed. Affected files are
4228 lib/silccore/silcpacket.[ch].
4230 Added silc_server_packet_decrypt_check to the server and
4231 silc_client_packet_decrypt_check to the client library.
4233 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4234 to send with specified source and destination information.
4236 * Channel message delivery between routers was broken after the
4237 channel key distribution was fixed earlier. The channel key
4238 was used be to distributed to other routers as well which is not
4239 allowed by the protocol. Now this is fixed and channel keys
4240 really are cell specific and the channel message delivery between
4241 routers comply with the protocol specification.
4243 * Fixed various commands in server to check also the global list
4244 for the channel entry and not just the local list. The affected
4245 file silcd/command.c.
4247 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Added assert()s to buffer formatting and unformatting routines
4250 to assert (if --enable-debug) when error occurs. Affected
4251 file: lib/silcutil/silcbuffmt.c.
4253 * Changed to auto-reconnect to check whether the remote host is
4254 router and register the re-connect timeout if it is. It used
4255 to check that whether we are normal server, but router must do
4256 auto-reconnect with another router as well. Affected file
4259 * Removed the [<key len>] option from CMODE command as the cipher
4260 name decides the key length, nowadays. See the defined ciphers
4261 from the protocol specification.
4263 * Added [<hmac>] option to the CMODE command to define the HMAC
4264 for the channel. Added SILC_CMODE_HMAC channel mode.
4266 * Added [<hmac>] option for the JOIN command so that user can
4267 select which HMAC is used to compute the MACs of the channel
4270 * Added Hmac field to the Channel Message Payload. The integrity
4271 of plaintext channel messages are now protected by computing
4272 MAC of the message and attaching the MAC to the payload. The
4273 MAC is encrypted. Now, it is clear that this causes some
4274 overhead to the size of the packet but rationale for this is that
4275 now the receiver can verify whether the channel message decrypted
4276 correctly and also when private keys are set for the channel the
4277 receiver can decrypt the packet with several keys and check from
4278 the MAC which key decrypted the message correctly.
4280 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4281 lib/silccrypt/silccipher.[ch].
4283 * Added silc_hash_len to return the digest length into the
4284 lib/silcrypt/silchash.[ch].
4286 * Rewrote parts of Silc Channel Payload interface in the
4287 lib/silccore/silcchannel.[ch]. The encode function now also
4288 encrypts the packet and parse function decrypts it.
4290 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Fixed a minor formatting bug in the SKE's key material processing.
4293 It actually might have processed the keys wrong way resulting
4296 * Redefined the mandatory HMAC algorithms and added new algorithms.
4297 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4298 and hmac-md5 truncated to 96 bits. The mandatory is now
4299 hmac-sha1-96. Rest are optional (including the one that used
4300 to be mandatory). Rationale for this is that the truncated HMAC
4301 length is sufficient from security point of view and can actually
4302 make the attack against the HMAC harder. Also, the truncated
4303 HMAC causes less overhead to the packets. See the RFC2104 for
4306 * Added new [hmac] configuration section. The SKE used to use
4307 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4308 is of course wrong. The official names that must be proposed in
4309 the SKE are the ones defined in the protocol specification
4310 (hmac-sha1-96 for example). The user can configure any hmac
4311 using any hash function configured in the [hash] section. At
4312 least, the mandatory must be configured.
4314 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4316 * Added HMAC list to the SKE proposal list. It has now both
4317 hash algorithm list and HMAC list. This makes the protocol
4318 incompatible with previous versions. The SKE now seems to work
4319 the way it is supposed to work, for the first time actually.
4321 * Defined plain Hash algorithms to the protocol specification.
4324 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Implemented support for key agreement packets into the server.
4327 Added functions silc_server_key_agreement and
4328 silc_server_send_key_agreement. Other than these functions,
4329 server has nothing to do with this packet.
4331 * Added support for private message key packets into the server.
4332 Added functions silc_server_private_message_key and
4333 silc_server_send_private_message_key.
4337 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4338 called in the protocol's final callback instead in the END
4339 protocol state. This makes a little more sense and in the same
4340 time in client we can use the same protocol routines for normal
4341 key exchange and to key agreement packet handling as well.
4343 * Added to both client's and server's KE protocol context the
4344 SilcSKEKeyMaterial pointer to save the key material. We will
4345 bring the key material to the protocol's final callback by doing
4346 this. The final callback must free the key material.
4348 * Added SKE's packet_send callback into client's KE protocol
4349 context so that the caller can choose what packet sending function
4350 is used. This way we can use different packet sending when
4351 doing normal SKE when doing key agreement packet handling (in
4352 the key agreement packet handling we do not want to encrypt
4355 * Implemented the responder side of the key agreement routines
4356 in the client. The client can now bind to specified port and
4357 accept incoming key negotiation. The key material is passed
4358 to the application after the protocol is over.
4360 * Implemented the processing of incoming Key Agreement packet
4361 in the client. Added function silc_client_key_agreement to
4364 * Implemented the intiator side of the key agreement routines
4365 in the client. The client can now initiate key agreement with
4366 another remote client. The key material is passed to the
4367 application after the protocol is over.
4369 * Created client_keyagr.c to include all the key agreement
4372 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4373 SILC_TASK_CALLBACK except that it is not static.
4375 * Created client_notify.c and moved the Notify packet handling
4376 from the client.[ch] into that file.
4378 * Created client_prvmsg.c and moved all private message and
4379 private message key routines from the client.[ch] into that file.
4381 * Create client_channel.c and moved all channel message and
4382 channel private key routines from the client.[ch] into that file.
4384 * Changed silc_client_get_client_by_id_resolve to resolve with
4385 WHOIS command instead of IDENTIFY command, in the file
4386 lib/silclient/idlist.c.
4388 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Implemented the SKE's responder side to the Client library.
4392 * When FAILURE is received to the protocol do not trust it
4393 blindly. Register a timeout to wait whether the remote closes
4394 the connection as it should do it, only after that process the
4395 actual failure. This was changed to both client and server.
4397 * Added client_internal.h to include some of the structures
4398 there instead of client.h in lib/silcclient/.
4400 * Added function silc_task_unregister_by_callback to unregister
4401 timeouts by the callback function.
4403 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Some "Incomplete WHOIS info" errors has been appearing on the
4406 log files. Took away the entry->userinfo check from WHOIS
4407 reply sending. The entry->userinfo is now " " if client did not
4408 provide one. I thought this was fixed earlier but something
4409 is wrong still. Let's see if the error still appears.
4411 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Fixed a minor bug in the login when the channel key is
4414 re-generated in the server. It used to generate the key in
4415 wrong order and thus caused problems in the channel traffic.
4417 * Fixed a minor bug in channel key distsribution after
4418 KICK command. The key was not sent to the router even though
4421 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Added silc_ske_process_key_material_data as generic routine
4424 to process any key material as the SILC protocol dictates. The
4425 function is used by the actual SKE library but can be used by
4426 applications as well. This relates to the private message keys
4427 and the channel private keys since they must be processed the
4428 same way the normal SILC session keys. The protocol dictates
4429 this. Affected files: lib/silcske/silcske.[ch].
4431 Added also silc_ske_free_key_material to free the
4432 SilcSKEKeyMaterial structure.
4434 * Defined silc_cipher_set_key function to set the key for
4435 cipher without using the object's method function. The affected
4436 files: lib/silccrypt/silccipher.[ch].
4438 * Implemented silc silc_client_add_private_message_key,
4439 silc_client_add_private_message_key_ske,
4440 silc_client_del_private_message_key,
4441 silc_client_list_private_message_keys and
4442 silc_client_free_private_message_keys functions in the
4445 Added functions silc_client_send_private_message_key to send
4446 the Private Message Key payload and silc_client_private_message_key
4447 to handle incoming Private Message Key payload.
4449 * Added Cipher field to the Private Message Key payload to set
4450 the cipher to be used. If ignored, the default cipher defined
4451 in the SILC protocol (aes-256-cbc) is used.
4453 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Removed lib/silcclient/ops.h file.
4457 Redefined parts of the SILC Client Library API. Created new
4458 file silcapi.h that deprecates the ops.h file and defines the
4459 published Client Library API. Defined also private message key
4460 API and channel private key API into the file.
4462 This is the file that the application must include from the
4463 SILC Client Library. Other files need not be included by
4464 the application anymore.
4466 * Added new key_agreement client operation callback and also
4467 defined the Key Agreement library API for the application.
4469 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4472 is used by clients to request key negotiation between another
4473 client in the SILC network. If the negotiation is started it
4474 is performed using the SKE protocol. The result of the
4475 negotiation, the secret key material, can be used for example
4476 as private message key.
4478 Implemented the Key Agreement payload into the files
4479 lib/silccore/silauth.[ch].
4481 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Redefined ciphers for the SILC protocol. Added some new ciphers
4484 and defined the key lengths for the algorithms. Changed the
4485 code accordingly. The default key length is now 256 bits.
4487 * Fixed SKE key distribution function silc_ske_process_key_material
4488 when the key length is more than 128 bits. The default key
4489 length in SILC is now 256 bits.
4491 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4492 to indicate unsupported algorithm.
4494 * Renamed rijndael.c to aes.c and all functions as well.
4496 * Fixed a long standing channel key setting bug in client library.
4497 Weird that it has never surfaced before.
4499 * Fixed bug in channel deletion. If the entire channel is removed
4500 then it must also delete the references of the channel entry
4501 from the client's channel list as the client's channel entry and
4502 the channel's client entry share same memory.
4504 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Implemented CONNECT and SHUTDOWN commands in the client.
4508 * Implemented CLOSE command to the client.
4510 * Added the function silc_idlist_find_server_by_name into the
4511 files silcd/idlist.[ch].
4513 Added the function silc_idlist_find_server_by_conn into the
4514 files silcd/idlist.[ch].
4516 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * DIE command was renamed to SHUTDOWN. Updated the both code
4521 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4522 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4524 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4527 * Added function silc_server_create_connection function to create
4528 connection to remote router. My server implementation actually
4529 does not allow router to connect to normal server (it expects
4530 that normal server always initiates the connection to the router)
4531 so the CONNECT command is only good for connecting to another
4534 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4537 or some other client was kicked from the channel.
4539 Implemented the handling of the notify type to both client
4542 Implemented silc_server_send_notify_kicked to send the KICKED
4543 notify. It is used to send it to the server's primary router.
4545 * Implemented the KICK command into server and client.
4547 * Added `query' argument to the silc_idlist_get_client function
4548 to indicate whether to query the client from server or not if
4551 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4552 to indicate that the client is not channel founder.
4556 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Removed the rng context from SilcPacketContext structure and
4559 changed that the packet routine uses the Global RNG API.
4561 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added support for quit message that client can "leave" on the
4564 channel when it quits the SILC. It is ditributed inside the
4565 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4567 Added silc_server_free_client_data that will take the
4568 signoff message as argument.
4570 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4572 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Updated parts of the protocol specification to keep it up
4577 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4580 payloads in one packet.
4582 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4583 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4584 use now the new List flag.
4586 * Also deprecated the following packet types: REPLACE_ID,
4587 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4589 * Added list support for Notify packet in server.
4591 * Added silc_server_send_notify_channel_change to send the
4592 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4593 the silc_server_send_replace_id.
4595 * Added silc_server_send_notify_nick_change to send the
4596 NICK_CHANGE notify type. Deprecates the function
4597 silc_server_send_replace_id.
4599 * Added silc_server_send_notify_join to send the JOIN notify type.
4600 Deprecates the function silc_server_send_new_channel_user.
4602 * Added silc_server_send_notify_leave to send LEAVE notify type.
4603 Deprecates the function silc_server_send_remove_channel_user.
4605 * Added silc_server_send_notify_cmode and
4606 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4607 types. Deprecates the silc_server_send_set_mode function.
4609 * Added SERVER_SIGNOFF notify type to indicate that server has
4610 quit. This means that all clients on the channel from that
4611 server will drop. This can be also used when netsplit happens.
4613 Deprecated REMOVE_ID packet type since it is not needed anymore
4616 Added silc_server_send_notify_server_signoff to send the
4617 SERVER_SIGNOFF notify type. Deprecates the function
4618 silc_server_send_remove_id.
4620 Added also silc_server_send_notify_signoff to send the
4621 SIGNOFF notify type.
4623 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4624 SILC protocol from this day on. Changed the protocol
4625 specification as well.
4627 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4628 notify type. It is used between routers to notify about
4629 topic changes on a channel.
4631 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4634 * Partly updated the protocol specification to comply with the
4635 changes now made. It is still though a bit outdated.
4637 * The JOIN notify type now takes one extra argument <Channel ID>.
4638 The packet used to be destined to the channel but now the
4639 JOIN type may be sent as list thus it is impossible to
4640 destine it to any specific channel. By adding this argument
4641 it is again possible.
4643 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added CREDITS file. The CHANGES and CREDITS file will appear
4646 in the distribution as well.
4648 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4651 types in the server's silcd/packet_receive.c.
4653 * Implemented CMODE and CUMODE to work in router environment.
4655 * Fixed minor encoding and decoding buglet from the
4656 lib/silccore/silcmode.c.
4658 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4661 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4663 * Changed all SilcConfigServer* and silc_config_server* to
4664 SilcServerConfig* and silc_server_config*, respectively.
4667 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Associated the ID (client or server ID) to the Authentication
4670 Payload to avoid any possibility of forging. Updated the
4671 protocol specification and the code accordingly.
4673 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * The RSA key length is now save to the RsaKey context in the
4676 key generation process in lib/silccrypt/rsa.c. The key length
4677 is now used to figure out the maximum size of the block allowed
4678 to be encrypted/signed.
4680 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4681 is equivalent to the silc_mp_mp2bin but does not allocate any
4684 * Changed silc_mp_mp2bin API to take length argument. If it is
4685 non-zero then the buffer is allocated that large. If zero, then
4686 the size is approximated using silc_mp_sizeinbase, which however
4689 * Created Global RNG API which is global RNG that application can
4690 initialize. After initializing, any routine anywhere in the
4691 code (including library) can use RNG without allocating a new
4692 RNG object. This was done to allow this sort of use of the
4693 RNG in code that has no chance to allocate RNG object. All
4694 applications currently allocate this and many routines in the
4695 library use this. Affected file lib/silccrypt/silcrng.[ch].
4697 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4698 it to use the Global RNG API.
4700 * Defined Authentication Payload into protocol specification that
4701 is used during SILC session to authenticate entities. It is
4702 used for example by client to authenticate itself to the server
4703 to obtain server operator privileges.
4705 Implemented this payload into the lib/silccore/silcauth.[ch].
4706 Implemented also routines for public key based authentication
4707 as the new protocol specification dictates.
4709 Moved definitions of different authentication methods from
4710 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4712 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4713 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4714 silc_pkcs_verify_with_hash functions into the file
4715 lib/silccrypt/silcpkcs.[ch].
4717 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * The client entry's userinfo pointer must be always valid.
4720 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4721 will fail since it requires the userinfo. Now, the userinfo
4722 is allocated as "" if actual userinfo does not exist. Actually,
4723 it must exist and it is totally Ok to drop client connections
4724 that does not announce the userinfo. However, we will make
4725 this workaround for now.
4727 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4728 to return the remote port by socket.
4730 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4733 SILC_SERVER_PENDING_EXEC and added an new macro
4734 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4735 data or when error occurs while processing the pending command.
4737 Added new argument `destructor' into silc_server_command_pending
4738 and to the SilcServerCommandPending object. This destructor is
4739 now called after calling the pending callback or if error occurs
4740 immediately. If error occurs the actual pending callback won't
4741 be called at all - only the destructor. The destructor may be
4742 NULL if destructor is not needed.
4744 All this applies for client library code as well. Similar
4745 changes were made there as well for the pending commands.
4747 In the client, the application must now allocate the
4748 SilcClientCommandContext with the silc_client_command_alloc
4751 * Added reference counter to the SilcServerCommandContext. Added
4752 function silc_server_command_alloc and silc_server_command_dup
4755 Same type of functions added to the client library for the same
4758 * Removed the cmd_ident from IDListData away since it is now
4759 global for all connections. It is the command identifier used
4760 in command sending and with pending commands. The affected file
4763 * Added reference counter to the SilcSocketConnection objecet to
4764 indicate the usage count of the object. The object won't be
4765 freed untill the reference counter hits zero. Currently only
4766 server uses this, and client ignores it. The client must be
4767 set to use this too later. The affected files are
4768 lib/silccore/silcsockconn.[ch]. Added also the function
4769 silc_socket_dup to increase the reference counter.
4771 This was mainly added because it is possible that the socket
4772 is removed underneath of pending command or other async
4773 operation. Now it won't be free'd and proper DISCONNECTING
4774 flags, etc. can be set to avoid sending data to connection that
4775 is not valid anymore.
4777 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4778 the connection. After that it sets SILC_SET_DISCONNECTED.
4779 It is, however, possible that the socket data is not still freed.
4780 The silc_server_packet_process now checks that data is not
4781 read or written to connection that is DISCONNECTED. The socket
4782 get's freed when the reference counter hits zero.
4784 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Changed the client operation API: channel_message operation's
4787 `sender' is now the client entry of the sender, not the nickname
4788 and the `channel' is the channel entry, not the channel name.
4790 In the private_message operation the `sender' is now also the
4791 client entry of the sender not the nickname.
4793 Affected file is lib/silcclient/ops.h and all applications
4794 using the client operations.
4796 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Moved the calling of ops->connect() from connect_to_server_final
4799 into receive_new_id functin since that is the point when the
4800 client is actually allowed to send traffic to network. The
4801 affected file is lib/silcclient/client.c.
4803 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4806 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4807 (if needs broadcasting) instead of broadcasting the packets one
4808 by one which would make a burst in the network traffic.
4810 * Added `broadcast' argument to the functions in silcd/server.[ch]
4811 silc_server_create_new_channel[_with_id] to indicate whether
4812 to send New Channel packet to primary router.
4814 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added new function into the silcd/server.[ch] files:
4817 silc_server_create_new_channel_with_id to create new channel with
4818 already existing Channel ID.
4820 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4821 lib/silccore/silcpacket.h. This packet is used t send list of
4822 Set Mode payloads inside one packet. Server uses this to set
4823 the modes for the channels and clients on those channels, that it
4824 announced to the router when it connected to it. The protocol
4825 specification has been updated accordingly.
4827 * The silc_server_new_channel did not handle the packet coming
4828 from normal server as it normally does not send that. However,
4829 when it announces its channels it does send it. Implemented
4830 the support for that.
4832 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4833 into the file lib/silccore/id.h.
4835 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Fixed memory leaks in the functions silc_idlist_del_client,
4838 silc_idlist_del_channel and silc_idlist_del_server in the file
4839 silcd/idlist.c. All of those leaked like a sieve.
4841 * Fixed some small memory leaks in the client's function
4842 silc_client_notify_by_server.
4844 * Added functions into silcd/server.c: silc_server_announce_clients,
4845 silc_server_announce_channels and silc_server_announce_server.
4846 These functions are used by normal and router server to announce
4847 to its primary router about clients, channels and servers (when
4848 router) that we own. This is done after we've connected to the
4851 These functions effectively implements the following packet types:
4852 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4853 and SILC_PACKET_NEW_ID_LIST.
4855 * Added new functions into the silcd/packet_receive.[ch]:
4856 silc_server_new_id_list, silc_server_new_channel_list and
4857 silc_server_new_channel_user_list to handle the incoming
4858 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4860 * Added support of changing Channel ID in the function
4861 silc_server_replace_id. If the server that announces a channel
4862 to the router already exists in the router (with same name but
4863 with different Channel ID), router is responsible to send
4864 Replace ID packet to the server and force the server to change
4865 the Channel ID to the one router has.
4867 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4868 client that the Channel ID has been changed by the router. The
4869 normal server sends this to the client. Client must start using
4870 the new Channel ID as the channel's ID.
4872 Implemented handling of this new type into lib/silcclient/client.c
4873 into the function silc_client_notify_by_server.
4875 * Added new function silc_idlist_replace_channel_id into the files
4876 silcd/idlist.[ch] to replace the Channel ID.
4878 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Call silc_server_command_identify_check always when processing
4881 the IDENTIFY command in silcd/command.c
4883 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4886 send keepalive packets. The packet can be sent by clients,
4887 servers and routers.
4889 Added function silc_socket_set_heartbeat into the file
4890 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4891 If not set, the heartbeat is not performed. The actual
4892 heartbeat is implemented in the low level socket connection
4893 library. However, application is responsible of actually
4896 Added silc_server_send_heartbeat to send the actual heartbeat
4897 packet into silcd/packet_send.[ch]. Server now performs
4898 keepalive with all connections.
4900 * Added silc_task_get_first function into lib/silcutil/silctask.c
4901 to return the timeout task with shortest timeout. There was a bug
4902 in task unregistration that caused problems. TODO has been
4903 updated to include that task system must be rewritten.
4905 * The client library will now resolve the client information when
4906 receiving JOIN notify from server for client that we know but
4907 have incomplete information.
4909 * Rewrote parts of silc_server_remove_from_channels and
4910 silc_server_remove_from_one_channel as they did not remove the
4911 channel in some circumstances even though they should've.
4913 * Encryption problem encountered in server:
4915 The LEAVE command used to send the Channel Key packet to the
4916 router immediately after generating it. However, the code
4917 had earlier sent Remove Channel user packet but not immediately,
4918 ie. it was put to queue. The order of packets in the router
4919 was that Channel Key packet was first and Remove Channel User
4920 packet was second, even though they were encrypted in the
4921 reverse order. For this reason, MAC check failed. Now, this
4922 is fixed by not sending the Channel Key packet immediately but
4923 putting it to queue. However, this is more fundamental problem:
4924 packets that are in queue should actually not be encrypted
4925 because packets that are sent immediately gets encrypted
4926 actually with wrong IV (and thus MAC check fails). So, packets
4927 that are in queue should be encrypted when they are sent to
4928 the wire and not when they put to the queue.
4930 However, the problem is that the current system has not been
4931 designed to work that way. Instead, the packet is encrypted
4932 as soon as possible and left to the queue. The queue is then
4933 just purged into wire. There won't be any fixes for this
4934 any time soon. So, the current semantic for packet sending
4937 o If you send packet to remote host and do not force the send
4938 (the packet will be in queue) then all subsequent packets to the
4939 same remote host must also be put to the queue. Only after the
4940 queue has been purged is it safe again to force the packet
4943 o If you send all packets immediately then it safe to send
4944 any of subsequent packets through the queue, however, after
4945 the first packet is put to queue then any subsequent packets
4946 must also be put to the queue.
4948 Follow these rules and everything works fine.
4950 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Added new function silc_server_remove_clients_by_server to
4953 remove all client entries from ID list when the server connection
4954 is lost. In this case it is also important to invalidate all
4955 client entires as they hold the invalid server entry. This
4956 fixes fatal bug when server has lost connection and will reconnect
4959 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Made some sanity checks to silc_server_daemonise like to check
4962 whether the requested user and group actually exists.
4964 * Added sanity check to SKE's silc_ske_responder_finish to check
4965 that the public and private key actually is valid.
4967 * Invalidate the client's nickname when receiving Replace ID
4968 packet and the Client ID is being replaced. This means that the
4969 server will query the nickname if someone needs it (client)
4972 * Sort the ID Cache in client library when the ID Cache data
4973 has changed (needs sorting).
4975 * Do not allow for SILC client to create several connections to
4976 several servers. The client does not support windows right now
4977 and generating multiple connections causes weird behaviour.
4979 Irssi-silc client does support windows and can handle several
4980 connections without problems, see: www.irssi.org and SILC plugin.
4982 * Fixed some places where client was added to the IDList. The
4983 rule of thumb is following (in order to get everything right):
4984 If the client is directly connected local client then the
4985 `connection' argument must be set and `router' argument must be
4986 NULL to silc_idlist_add_client function. If the client is not
4987 directly connected client then the `router' argument must
4988 bet set and the `connection' argument must be NULL to the
4989 silc_idlist_add_client function.
4991 * The funtion silc_server_packet_send_local_channel actually did
4992 not check whether the client was locally connected or not. It
4993 does that now. Fixed a bug related to LEAVE command.
4995 * Fixed Remove Channel User payload parsing bug in server's
4996 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4998 * The server's silc_server_save_channel_key now checks also the
4999 global ID list for the channel as it might not be in the local
5000 list. Fixed a bug related to LEAVE command.
5002 * Is this the end of the [<unknown>] buglet that has been lurking
5003 around for a long time? A little for loop fix in server's
5004 silc_server_command_whois_parse that is used by both IDENTIFY
5005 and WHOIS command. At least, this was a clear bug and a cause
5006 of one type of [<unknown>] buglet.
5008 * WHOIS and IDENTIFY commands call the function
5009 silc_server_command_[whois/identify]_check function even if
5010 we are not router server.
5012 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Added --with-gmp configuration option. If set the GMP
5015 is always compiled in the SILC source tree. If not set then
5016 it is checked whether the system has the GMP3 installed. If
5017 it has then the GMP won't be compiled (the system's headers
5018 and library is used), if it doesn't have it then the GMP is
5019 compiled in the SILC source tree.
5021 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Changed RSA private exponent generation to what PKCS #1
5024 suggests. We try to find the smallest possible d by doing
5025 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5026 not security fix but optimization.
5028 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added new config entry [Identity] to fork the server and run
5031 it as specific user and group. A patch from Bostik.
5033 * Imported Dotconf configuration library into lib/dotconf.
5034 This will be used to create the SILC configuration files later.
5035 It will appear in the distsribution after this commit.
5037 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * A big code auditing weekend happening. Auditing code for
5040 obvious mistakes, bugs and errors. Also, removing any code
5043 Removed files for being obsolete:
5045 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5046 inline in the file lib/silcutil/silcbuffer.h)
5048 o lib/silcutil/silcbufutil.c (the header has inline versions)
5050 Changed code to fix possible error conditions:
5052 o The buffer formatting routines now check that the destination
5053 buffer really has enough space to add the data. This applies for
5054 both buffer formatting and unformatting
5055 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5056 unformatting was changed to accomodate following rules:
5057 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5058 sent to the function while XXX_*STRING will not allocate or copy
5059 the data into the buffer. Instead it sets the pointer from the
5060 buffer into the pointer sent as argument (XXX_*STRING used to
5061 require that the pointer must be allocated already). This change
5062 makes this whole thing a bit more consistent and more optimized
5063 (note that the data returned in the unformatting with XXX_*STRING
5064 must not be freed now). The routines return now -1 on error.
5066 o Tried to find all code that use buffer_format and buffer_unformat
5067 and added return value checking to prevent formatting and
5068 especially unformatting errors and possible subsequent fatal
5071 o Changed ske->x and ske->KEY to mallocated pointers in
5072 lib/silcske/silcske.h. Fixed possible data and memory leak.
5074 o Added return value checking to all *_parse* functions. Fixed
5075 many memory leaks as well.
5077 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5078 so that buffer overflows would not happen. All code now also
5079 checks the return value as it can fail.
5081 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Added reconnection support to server if the normal server looses
5084 its connection to the router (for example if router is rebooted).
5085 The server performs normal reconnection strategy implemented
5086 to the server. Affected file silcd/server.c.
5088 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Added new packet type SILC_PACKET_SET_MODE that is used to
5091 distribute the information about changed modes (for clients,
5092 channels and clients channel modes) to all routers in the
5093 network. Updated the protocol specification accordingly.
5095 Added functions into silcd/packet_send.c and
5096 silcd/packet_receive.c: silc_server_send_set_mode,
5097 silc_server_set_mode.
5099 Added new files silcmode.[ch] into lib/silccore that implements
5100 the encoding and decoding of Set Mode Payload. Added new type
5101 SilcSetModePayload. Moved the definitions of different modes
5102 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5104 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Oops, a little mistake in server's connection authentication
5107 protocol. The protocol is not ended with FAILURE but with
5108 SUCCESS if the authentication is Ok. :) Affected file is
5111 * Implemented NICK_CHANGE notify handling in server in the file
5112 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5113 the local clients on the channel. After the changing nickname
5114 in router environment snhould work and the [<unknown>] nickname
5115 should appear no more.
5117 The silc_server_replace_id function that receives the Replace ID
5118 payload now sends the NICK_CHANGE notify type also in the file
5119 silcd/packet_receive.c
5121 * Changed WHOIS and IDENTIFY command to support the maximum amount
5122 of arguments defined in protocol specs (3328 arguments). This
5123 fixed a bug that caused problems when there were more than three
5126 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added extra parameter, command identifier, to the
5129 silc_client_send_command so that explicit command identifier
5132 Changed that ID list routines uses specific command identifier
5133 when sending WHOIS/IDENTIFY requests to the server so that they
5134 can be identified when the reply comes back.
5136 Affected files lib/silcclient/command.[ch],
5137 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5139 * Added `sender' argument to silc_server_packet_send_to_channel
5140 to indicaet the sender who originally sent the packet to us
5141 that we are now re-sending. Ignored if NULL. Affected file
5142 silcd/packet_send.[ch].
5144 * Added some server statistics support in silcd/server_internal.h
5145 SilcServerStatistics structure and around the server code. Also
5146 send some nice statistics information when client is connecting
5149 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Fixed channel ID decoding in server's JOIN command reply in
5152 silcd/command_reply.c
5154 * Fixed braodcasting of replace ID payload to not to send it if
5155 we are standalone server in silcd/packet_receive.c.
5157 * Fixed all channel message sending routines to not to send
5158 packets to clients that has router set, since they are routed
5159 separately in the same function earlier. Affects file
5160 silcd/packet_send.c and all channel packet sending functions.
5162 * In USERS reply, res_argv[i] are not allocated, the table
5163 is allocated. Thus changed that free the table, not its
5166 * In server's whois_check and identify_check if the client is
5167 locally connected do not send any WHOIS commands - they are not
5170 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Fixed some minor bugs in client when sending WHOIS command. The
5173 arguments was in wrong order.
5175 * Removed statis function add_to_channel from server in
5176 silcd/command.c that was previously used with the joining but
5179 * Tested USERS command in router environment successfully with two
5180 routers, two servers and two clients.
5182 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Reorganized the USERS command and command reply in client library
5185 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5186 When the command is given by user we register a pending command
5187 callback that will reprocess the command after the reply has been
5188 received from the server. When reprocessing the packet we then
5189 display the information. Thus, the USERS information is displayed
5190 now in the command callback instead of in the command reply
5191 callback. The processing of the command is same as previously
5192 when server has sent the command reply in the JOINing process.
5194 * Added to USERS command in silcd/command_reply.c to join the client,
5195 we didn't use to know about, to the channel after we've created
5196 a client entry for it. Also, for clienet we did know already still
5197 check whether it is on the channel or not and add it if not.
5199 * Removed silc_server_command_join_notify as the function and its
5202 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Changed the client's pending command handling to the same as the
5205 server's pending command handling. It is also now possible to
5206 execute command reply functions from other command reply
5207 function as the function callbacks for commands and command
5208 replies are one and same. The pending commands are not static
5209 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5210 in client connection context. Thus, pending commands are server
5211 connection specific as it is convenient.
5213 Changed the function silc_client_command_pending and
5214 silc_client_command_pending_del and added new function
5215 silc_client_command_pending_check. Removed the
5216 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5219 * Added cmd_ident, current command identifier, to the client
5220 connection context in lib/silcclient/client.h to keep track on
5221 command identifiers used in command sending. Client's command reply
5222 function handling now supports the mandatory command identifiers.
5224 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5225 funtions in client to fully support pending command callbacks.
5227 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5228 as one of the arguments to the application in the command reply
5231 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5232 before first releasing SILC but came back. Now it is removed again
5233 and should come back nomore. The FORWARDED flag was used only
5234 by the JOINing procedure by forwarding the command packet to router.
5235 Now, the JOINing procedure has been changed to more generic (due
5236 to various router environment issues) and FORWARDED is not needed
5237 anymore for anything. The protocol specification is yet to be
5240 Now, removed silc_server_packet_forward from server and the flag
5241 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5243 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Renamed NAMES command to USERS command. The NAMES was named that
5246 due to historical reasons. Now it is renamed. Also, rewrote
5247 parts of the USERS command. The nickname list is not sent anymore
5248 by the server. Only Client ID and mode lists are sent in the USERS
5249 command. Changed this also to the protocol specification.
5251 The client now resolves the names and stuff after it receives
5252 the USERS list from the server when joining to the channel.
5254 * WHOIS and IDENTIFY commands has been changed to support multiple
5255 Client ID's per command. One can now search for multiple users
5256 in the network by sending only one WHOIS or IDENTIFY command.
5257 Changed the code and the protocol specifications.
5259 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5260 uses silc_server_command_whois_parse to parse the request. */
5262 * If normal server, do not parse the WHOIS and IDENTIFY requests
5263 before sending it to the router. Saves some time.
5265 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Fixed JOIN command on client library. Wrong number of arguments
5268 used to crash the client.
5270 * Added silc_server_channel_has_global function to check whether
5271 channel has global users or not.
5273 * Added silc_server_channel_has_local function to check whether channel
5274 has locally connected clients on the channel.
5276 * The silc_server_remove_from_one_channel now checks whether the
5277 channel has global users or not after given client was removed from
5278 the channel. It also checks whether the channel has local clients
5279 on the channel anymore. If it does not have then the channel entry
5280 is removed as it is not needed anymore.
5282 * The silc_server_notify now checks on JOIN notify whether the joining
5283 client is one of locally connected or global. If it is global then
5284 the channel has now global users on the channel and that is marked
5285 to the channel entry. Also, it now saves the global client to
5286 global list who is joining and JOINs it to the channel. This is
5287 for normal server, that is.
5289 Changed silc_server_send_notify_on_channel,
5290 silc_server_packet_relay_to_channel and
5291 silc_server_packet_send_to_channel check if we are normal server
5292 and client has router set (ie. global client) do not send the
5293 message to that client, as it is already routed to our router.
5295 * Implemented LEAVE notify type handling in silc_server_notify
5298 * Tested LEAVE command in router environment successfully. Tested
5299 with two routers, two servers and two clients.
5303 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5305 * Implemented SIGNOFF notify type handling in silc_server_notify
5308 * silc_server_remove_id now removes the client entry from all channels
5309 it has joined and thusly sends SIGNOFF notify type.
5311 * Rewrote the NAMES list generation in server by removing two excess
5312 loops. The lists are created now inside one loop.
5314 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * silc_server_remove_channel_user checks now also global list
5317 for channel and client.
5319 * silc_server_new_channel_user checks now both local and global
5320 list for channel and client. Fixed a bug in client id decoding.
5321 Used to decode wrong buffer.
5323 * silc_server_channel_message checks now both local and global
5324 list for channel entry.
5326 * Tested channel joining (hence JOIN) in router environment
5327 successfully. Tested with two routers, two servers and two
5330 * Tested channel message sending in router environment successfully.
5332 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * Added silc_server_save_channel_key into server.[ch] to save the
5335 received channel key in Channel Key payload processing. It is
5336 also used in JOIN command reply handling.
5338 Equivalent function silc_client_save_channel_key added into
5339 client.[ch] into client library.
5341 * Changed JOIN command reply to send information whether the channel
5342 was created or not (is existing already) and the channel key
5343 payload. Changed protocol specs accordingly.
5345 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5346 the request was sent by ID and not by nickname. Crashed on
5349 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5352 now correctly save the received data.
5354 * silc_server_free_sock_user_data now notifies routers in the
5355 network about entities leaving the network.
5357 At the same time implemented functions silc_server_remove_id
5358 and silc_server_send_remove_id to receive and send REMOVE_ID
5359 packets. The packet is used to notify routers in the network
5360 about leaving entities. The ID removed will become invalid in
5363 * Added function silc_idlist_del_server into server. Removes and
5364 free's server entry from ID list.
5366 * silc_server_private_message function now checks, if we are router,
5367 that the destination ID really is valid ID, naturally.
5369 * In router when NEW_ID packet is received (for new client) the
5370 hash of the Client ID is saved in the ID Cache but the
5371 client->nickname is set to NULL, instead of putting the hash
5374 IDENTIFY command now also checks that client->nickname must be
5375 valid. If it is not if will request the data from the server who
5376 owns the client. Added new function
5377 silc_server_command_identify_check.
5379 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5380 to set the command to already allocated Command Payload.
5382 * Tested private message sending in router environment with two
5383 routers, two servers and two clients. Fixed minor bugs and now
5386 * Fixed segfault from client's NAMES command. Used to crash if
5389 * Forwarded packets must not be routed even if it is not destined
5390 to the receiver. Changed server code comply with this.
5392 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Added `require_reverse_mapping' boolean value to ServerParams
5395 structure. If TRUE (not default) the server will require that
5396 the connecting host has fully qualified domain name.
5398 If the reverse mapping is not required and hostname could not be
5399 found the IP address is used as hostname.
5401 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Implemented version string checking to both client and server.
5404 The check is incomplete currently due to the abnormal version
5405 strings used in development version of SILC.
5407 * Changed all command functions in server to use the new
5410 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Changed char *data to unsigned char *data in ID Cache system to
5413 support binary data as ID Cache data. Changed code to support
5414 binary data in lib/silccore/idcache.c.
5416 * Renamed silc_server_packet_relay_command_reply to
5417 silc_server_command_reply as it is normal packet receiving
5418 function. Rewrote the function to accept command replys for
5419 servers and not only for clients.
5421 * Mark remote router always as registered server if we are connecting
5422 to it. Otherwise, commands sent by the router to us are ignored.
5424 * All ID List find routines now returns the ID Cache Entry pointer
5425 as well if requested.
5427 * WHOIS command works now in router environment, tested with two
5428 routers, two servers and two clients.
5430 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5431 in router environment (as it is almost equivalent to WHOIS) but
5432 hasn't been tested thoroughly. Added new functions:
5434 silc_server_command_identify_parse
5435 silc_server_command_identify_send_reply
5436 silc_server_command_identify_from_client
5437 silc_server_command_identify_from_server
5439 * Disabled route cache adding because adding two different ID's with
5440 same IP replaces the old cache entry thus giving wrong route.
5441 The entry->router->connection is always the fastest route anyway
5442 so route cache may not be needed. Of course, new routes maybe
5443 established after receiving the ID when the entry->router->connection
5444 might not be anymore the most optimal.
5446 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Add route cache for received ID for fast routing.
5450 * Added silc_server_packet_route to route received packet on router
5451 that is not destined to us.
5453 * Renamed silc_server_get_route to silc_server_route_get.
5455 * Added id_string and id_string_len fields into SilcServer to
5456 include encoded ServerID for fast comparing without excess
5457 encoding of the ID's.
5459 * Cleaned up WHOIS command on server side. Added following static
5462 silc_server_command_whois_parse
5463 silc_server_command_whois_check
5464 silc_server_command_whois_send_reply
5465 silc_server_command_whois_from_client
5466 silc_server_command_whois_from_server
5468 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5469 arguments in command replies. All command functions should be
5470 updated to use this macro.
5472 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Minor typo fixes on command reply handling on server.
5476 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Added silc_server_command_add_to_channel internal routine to add
5479 the client to the channel after router has created the channel and
5480 sent command reply to the server.
5482 * Added generic silc_server_send_command to send any command from
5485 * Use static buffer with ID rendering instead of duplicating data.
5487 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Fixed a channel user mode bug when joining to a channel server gave
5490 everybody channel founder rights, oops.
5492 * We mark ourselves as the router of the incoming server connection
5493 if we are router ourselves. This way we can check in some packet
5494 sending functions whether it is locally connected server. For
5495 incoming router connections we put NULL.
5497 * For router sending packets locally means now always sending the
5498 packet cell wide; to local clients and local servers. For normal
5499 server sending packet locally means sending it to only local
5502 * Fixed the JOIN command to really work in router environment. If the
5503 channel is created it is always created by the router. Router is
5504 also responsible of making the initial joining to the channel,
5505 sending JOIN notify to the sending server and distributing
5506 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5507 does not exist server doesn't do anything else but forward the
5508 command to the router which performs everything.
5510 * Added silc_server_send_channel_key function to send the Channel Key
5513 * Added silc_server_create_channel_key to create new channel key. The
5514 channel key is now re-generated everytime someone joins or leaves
5515 a channel, as protocol dictates. Note: channel->key_len is the
5518 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5521 packet_receive.[ch] to separate packet sending and receiving
5522 routines. The server.[ch] now includes everything else including
5523 actual packet processing (writing and reading data) and other
5526 Renamed silc_server_private_message_send_internal to
5527 silc_server_send_private_message. The routine is still though
5528 used only to relay private messages as server does not send
5529 private messages itself.
5531 Renamed silc_server_new_channel to silc_server_create_new_channel
5532 and added new function sicl_server_new_channel that handles the
5533 incoming New Channel packet. Added also new sending function
5534 silc_server_send_new_channel to send New Channel Payload.
5536 * Added new function silc_server_notify to process incoming notify
5537 packet to the server/router. Server may then relay the notify
5538 to clients if needed.
5540 * Added new function silc_server_new_channel_user to process incoming
5541 New Channel User packet. Router will redistribute the packet and
5542 send JOIN notify to its local clients and locally connected servers
5543 if needed. Normal server will send JOIN notify to its local client
5544 on same channel when received this packet. Added also corresponding
5545 sending function silc_server_send_new_channel_user to sent the
5548 * Added boolean route argument to send_notif_to_channel and
5549 packet_send_to_channel functions to attempt to route the packet
5550 if it is TRUE and send only locally if it is FALSE.
5552 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * silc_server_replace_id now broadcasts the received replace ID
5555 packet if it is not broadcast packet already. The router must
5556 broadcast to inform other routers about changed ID.
5558 * Added backpointer to server's router into SilcServer context in
5559 silcd/server_internal.h.
5561 * Fixed silc_server_packet_broadcast to send correct broadcast
5564 * The channel key is now distributed to the local client as soon
5565 as it is received from the router (in router environment) so that
5566 no other packet may be sent for the channel until client has
5569 * silc_server_remove_channel_user now broadcasts the received
5570 Remove Channel User packet if it is not broadcast packet already.
5571 The router must broadcast to inform other routers about removed
5574 * Added users field into SilcPacketContext that is a reference count
5575 of the context. One can increase the reference count by calling
5576 silc_packet_context_dup which is now changed to just increase the
5577 reference count instead of duplicating the data. The reference
5578 count is decresed by calling silc_packet_context_free that will
5579 free the data after the reference count hits zero.
5581 For now on the packet context and everything allocated into it
5582 (including the raw packet from network) must be freed by calling
5583 the new silc_packet_context_free function. Added also new function
5584 silc_packet_context_alloc that must be used now to allocate the
5585 context. This also means that if a routine is asynchronous from
5586 silc_[client/server]_packet_parse_type the packet context must
5587 be duplicated by calling silc_packet_context_dup. Otherwise it
5588 gets free'd after silc_[client/server]_packet_parse_type returns.
5589 Also, one must remember that if packet is duplicated then its
5590 reference count must be decresed by calling the free function as
5591 many times as it was duplicated.
5593 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5594 from both client and server.
5596 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Made joining to a channel working in router environment.
5600 * Cleaned up JOIN command on server side and create function
5601 silc_server_command_join_channel internal routine to make the
5604 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Changed silc_command_pending list to SilcDList. Also, added
5607 `ident' field to SilcServerCommandPending structure to identify
5608 the reply and to call correct callback.
5610 Added silc_server_command_pending_check function to replace the
5611 corresnponding macro. The silc_command_pending list is not
5614 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5615 to set identifier to previously allocated Command Payload. It
5616 is used to set identifier for command when resending Command
5619 * Added silc_command_payload_encode_payload to encode Command
5620 Payload buffer from SilcCommandPayload structure.
5622 * Added silc_argument_payload_encode_payload to encode Argument
5623 payload buffer from SilcArgumentPayload structure.
5625 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Changed WHOIS command to support router connection on server side.
5628 The whois request is always sent to router unless the server is
5629 standalone server. After server has received the reply from the
5630 router will it send the reply to the client.
5632 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5633 broadcast received broadcast packet. The function is used only
5634 by router. The broadcast packet is always sent to the router's
5637 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5638 render given ID to printable string, for log files for example.
5640 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Made basic router to router connections working. At least they
5643 can now connect to each other but nothing really works the way
5644 they are supposed - yet.
5646 * Added new initiator token to RouterConnection configuration
5647 file in silcd/serverconfig.[ch]. It is used to tell whether we
5648 are the initiator to the remote router or whether we'll expect
5649 the other end to connect.
5651 * Moved registering of listener task to silc_server_init, hence
5652 the server starts listenning as soon as it is run, even if it
5653 does not have connections to other routers. Let's see how well
5656 * Changed default connection retry timeouts for more suitable in
5659 * Removed cipher and such arguments from silc_idlist_add_client
5660 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5661 Added new function silc_idlist_add_data to add the keys and stuff
5664 * Added SilcIDListData structure and added it to SilcClientEntry
5665 and SilcServerEntry as their first field in the structure. This
5666 way we can explicitly cast the ID entries to the SilcIDListData
5667 structure and get common data for the entries. In past, we had
5668 to first check what type of connection it is and then cast it to
5669 correct ID entry type. Now, we can directly cast the opaque
5670 pointer to the SilcIDListData (no matter what ID entry it actually
5671 is) and get the data needed.
5673 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5676 in some circumstances even if threre were timeout tasks, though not
5677 IO tasks, but tasks anyway. Now fixed.
5679 * Defined SilcServerConnection structure to hold connection specific
5680 stuff about directly connected servers and routers. The definition
5681 is currently in silcd/server_internal.h. I thought about having
5682 a bit more important role fro this struct but for now it is used
5683 only when connecting to other server (or router actually).
5685 * Added connecting retry support in server when connecting to
5686 router(s). The retry feature implement exponential backoff
5687 algorithm. Also, added SilcServerParams structure to hold default
5688 parameters for server. For now, it include these retry settings
5689 and are hard coded. After server is moded to be as Silc Server
5690 Library this structure will be more important.
5692 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Changed client librarys channel->clients table to SilcList and
5695 changed code accordingly.
5697 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Changed client's channel table to SilcList and changed code
5700 accordingly. Also changed SilcChannelClientEntry to include back-
5701 pointer to the channel so that client entry can use that structure
5702 as list as well and we have fast cross-reference to the channel.
5703 This change dramatically decreased the complexity of channel
5704 handling with client entry and vice versa (removed one extra
5705 loop when searching for channel entry from many functions).
5707 * Changed server->sim from table to SilcDList and changed code
5710 * NAMES command can now be used from user interface. It will show
5711 the user list on the channel, neatly.
5713 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5714 Code now saves realname of the user if it becomes available.
5716 * Renamed configure.in to configure.in.pre and made ./prepare
5717 script to automatically add correct version string to
5718 configure.in which it creates from configure.in.pre.
5720 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * NAMES command reply now shows users mode with the nickname when
5725 * Moved silc_client_ch[u]mode[_char] functions from
5726 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5727 place sucks, they are utility functions and should be in some
5730 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5732 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5735 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Added TRQ (efficient deque and list library) into lib/trq. This is
5740 a very good list library that is currently used in the SILC. Defined
5741 SilcList API over the library because I didn't like the API very
5742 much. See lib/trq/silclist.h for the API and examples of how to
5743 use the API. Fixed various places in the code to use the new
5744 SilcList API. The SilcList is meant for lists that has a structure
5745 already defined as a list. It is not suitable to add just some
5746 context to the list (in TRQ, the context is the list actually).
5748 So, I defined SilcDList that can be used for the purpose where
5749 predefined list structure does not exit. This can be used as
5750 such list. Now some context just can be added to the SilcDList.
5751 Currently this list is not used in the SILC just yet, though there
5752 are a lot places where this can replace dynamically allocated
5753 tables and I will fix these places, later, to use SilcDList.
5754 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5755 and use TRQ internally).
5757 Also fixed some annoying warning messages that the original TRQ
5758 code generated. Also minor changes to TRQ's Makefile.in.
5760 * Added support for querying by Client ID to both WHOIS and
5761 IDENTIFY commands into server, as required by the protocol.
5763 * Removed method function pointers from SilcBuffer structure. They
5764 weren't used to anything and just increased the context size for
5765 no good reason. This change also made silc_buffer_alloc and
5766 silc_buffer_free functions inline functions.
5768 * Disabled command flooding detection support until it's fixed so
5769 that it accepts commands in but does not execute them more than once
5772 * Added silc_net_localhost(), to return local hostname, into
5773 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5774 that must be initialized before calling silc_client_init.
5776 * Added new function: silc_server_send_notify_on_channels to send
5777 notify messages to all channels client has joined. It is assured
5778 that the message is sent only once per client.
5780 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5781 lib/silcutil/silcutil.[ch] as silc_format function. The new
5782 function is generic and is used by server as well, not only by
5783 the logging routines.
5785 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5786 the provided version string was not acceptable. Added new function:
5787 silc_ske_check_version into lib/silcske/silcske.h. The function
5788 must be implemented by the application (client or server) and it
5789 does not reside in the SKE library. The function checks the version
5790 string remote end sent.
5792 * Added back pointers (to opaque context and to SilcSocketConnection)
5793 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5795 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5796 duplicate packet context structure.
5798 * Changed `notify' client operation to send same arguments as client
5799 receives from server except for ID's. ID's are mapped to correct
5800 ID entry and that is returned. Also, if channel entry is not sent
5801 by server but the notify is for channel the channel entry is sent
5802 to application (otherwise application doesn't know that it is for
5803 channel (library gets it from packet's Destination ID)).
5805 * Added silc_client_remove_from_channels into client library to
5806 remove a client from all channels it has joined to. Used when
5807 received SIGNOFF notify from server. Added also new function
5808 silc_client_replace_from_channels to replace old ID entry with
5809 new ID entry on all channels. Used when received NICK_CHANGE
5812 * Fixed ID Cache list handling in silc_idlist_get_client in
5813 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5814 to get (or query) client by ID.
5816 * Updated TODO list.
5818 * Added connection authentication status message defined by the
5819 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5820 support for these into the code in client and server side.
5822 * Added generic function silc_client_send_command to send any command
5823 with variable argument list. Application should use this function
5824 to send commands if the command functions provided by the library
5825 does not suite for the application's user interface needs.
5827 * Added new `failure' client operation. Application is notified about
5828 received failure packet if client is executing a protocol. In this
5829 case the protocol's execution has failed.
5831 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5832 is required by the protocol.
5834 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5835 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5838 * Added status flag to SilcSKE object to indicate realtime status
5839 of the SKE protocol.
5841 * Application receives now exactly same command reply arguments as
5842 the library receives from server. However, if ID is received the
5843 corresponding ID entry is returned to the application (eg. Client
5844 ID is mapped to correct SilcClientEntry entry and that is returned).
5845 Changed command_reply client operation due to this change.
5847 * Changed all ID's in commands and in command replys as ID Payloads.
5848 Change affected both client and server side codes.
5850 All ID's sent in SILC network (with execption of ID's in SILC
5851 Packet header) are sent in ID Payload to support variable length
5854 * Server now notifies nick changes and notifies all clients on
5855 the channels about the new nickname (about the new Client ID,
5858 * Implemented CMODE command to change channel modes. Supports all
5859 channel modes defined by the protocol specs except ban and invite
5860 lists. (Also, private channel key mode is supported but support for
5861 setting private channel key in client is missing, thus, this mode
5862 has no effect on client side (except that server requires that the
5863 client uses private channel key and normal channel traffic does not
5866 Also, invite mode works per se, but INVITE command does not work
5867 yet correctly, so you can set channel as invite only channel but
5868 inviting clients to the channel does not work (it is yet to be
5869 thought what's the best way to do it).
5871 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5872 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5873 Implemented CUMODE command to change user's mode on the channel.
5874 Supports all modes defined by the protocol specs.
5876 * Added NAMES command reply to return users modes on the channel.
5878 * Removed unnecessary and slow ciphers from lib/silccrypt.
5880 * Set SO_KEEPALIVE option to connection sockets by default.
5882 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5884 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5885 redefined the Notify Payload into protocol specs.
5887 * Added silc_id_payload_parse_id to get ID directly from raw
5890 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5893 accept searching by Client ID as well.
5895 * Added support for LEAVE and SIGNOFF notify types in client library.
5897 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5898 to parse ID Payload from raw data.
5900 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added flags parameter into silc_ske_assemble_security_properties
5903 function in lib/silcske/silcske.[ch].
5905 * Changed notify client operation to fit better for notify messages
5906 sent by server. The notify payload received from server is now
5907 passed to the application (after parsing it to SilcNotifyPayload).
5908 It is application's responsibility to retrieve the arguments
5909 from the payload and show the message the way it wants. The message
5910 sent by server is implementation specific.
5912 * Changed public keys to comply with the protocol specification.
5913 Old public keys are not supported anymore and are not compatible.
5915 * Removed nickname from Channel Payload as the latest draft removed
5916 it. The client must resolve the nickname from the NAMES command
5917 reply received when it joined the channel.
5919 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5921 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Fixed some errors in protocol specification drafts.
5925 * Created lib/silccore/silcnotify.c to implement Notify Payload
5926 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5927 generic payloads described by protocol specifications. The file
5928 includes implementations for ID Payload and Argument Payload.
5930 * Changed Command Payload implementation to use the new Argument
5931 Payload. Changed command_xxxx_payload to command_payload_xxxx
5932 to comply with SILC coding conventions.
5934 * Added suppport for Argument Payload handling in Notify Payload
5935 implementation as protocol requires it. Added the new support
5936 into server and client lib as well.
5938 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added support for multiple nicknames on same channel. [n] is
5941 added locally to the nickname if there are more than one same
5942 nicknames on the channel.
5944 * Server now sends all nicknames that matched WHOIS request.
5945 Client also shows the list received from server.
5947 * Added TOPIC command to client side. User can now set and show
5948 current topic on channel.
5950 * Added MOTD command to client and server. Also, server sends the
5951 motd when client connects to the server.
5953 * Changed version strings to comply ISO 8601.
5955 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Fixed protocol error handling in client library. It should now
5958 cope even if the SKE fails for some reason.
5960 * Made new protocol specification drafts for submitting to IETF.
5962 * Implemented TOPIC command to server in silcd/command.c.
5964 * Added two new notify types into lib/silccore/silcnotify.h:
5965 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5966 notify nickname change and topic setting/change on a channel.
5968 * API change of command_reply operation in client library. The
5969 application gets now the status type received from server as well.
5971 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5975 * Cras fixed and optimized the packet handling even further and
5976 it should work now. Minor change to the prototype of function
5977 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5979 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Added new function into lib/silcutil/silcschedule.[ch]:
5982 silc_schedule_with_fd to select() a specified fd. The function
5983 returns after timeout expires or data arrives or goes. The
5984 function is used by packet routines to wait that all data is
5985 received from network.
5987 * Fixed data reading from network in lib/silccore/silcpacket.c.
5988 The code now assures that all data is read from the fd and then
5989 continues packet processing. This was a bug fix since the code
5990 used to drop some data in some circumstances.
5992 * Added new function into lib/silcclient/client.[ch]:
5993 silc_client_start_key_exchange to start key exchange after
5994 connection has been established to server. The code internally
5995 now uses this funtion but its main purpose was to provide it
5996 for applications that perform their own connecting. After
5997 application has created a connection it merely calls this
5998 function to start the key exchange between client and server.
5999 The library takes care of everything else after that.
6001 Updated also lib/silcclient/README to explain the usage of
6004 * Do not send to application information that connection has
6005 been established. Application gets notified it by connect
6008 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Applied cras's patch to add silc_schedule_one function. The
6011 function runs scheduler once and returns.
6013 * Fixed the scheduler after cras messed it up. The timeout
6014 handling works now as it's supposed to work.
6016 * Added into lib/silccore/ silcnotify.h to include notify
6017 message types support. Changed silc_server_send_notify*
6018 functions, in server.[ch], to support those new notify types.
6019 Added the support for the notify types into client library,
6020 as well. Added new notify client operation into ops.h in
6023 * Changed silc_server_packet_send_to_channel to send normal
6024 packets instead of just channel message packets. The function
6025 is now used to send the notify packets to channels. It is not
6026 used to send channel message packets anymore, as server never
6029 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6030 va_arg()s as it seems to require it nowadays. I guess, if SILC
6031 is compiled with older va_arg() the new code should work anyway.
6033 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Splitted core library. Core library (lib/silccore) includes
6036 now only SILC protocol specific core (and common) components.
6037 Created new utility library (lib/silcutil) that includes more
6038 generic purpose stuff. The stuff for util library was taken
6039 from the old core library. This was minor and easy split.
6041 * Created SILC Client Library (lib/silcclient) that includes
6042 implementation of the SILC client without user interface. This
6043 was major move from silc/ directory. The code has been changed
6044 so that it is transparent towards the user interface. The
6045 silc/ directory includes now the same user interface as before
6046 and it uses the new client library. Read lib/silcclient/README.
6047 Basicly, the client library performs everything else related
6048 to SILC except user interface handling. Also, configuration
6049 files are considered to be part of user interface and library
6050 does not handle them.
6052 This change also changed a lot of structures, function naming etc.
6053 Most important change was that SilcClientWindow object was
6054 renamed to SilcClientConnection in the client library. Created
6055 also new file lib/silcclient/ops.h. Also added new files
6056 silc/local_command.[ch] and silc/client_ops.[ch].
6058 All these changes were made to make it easier for user interface
6059 designers to create what ever user interface for the SILC client
6062 It is also expected that the server will be moved to lib
6063 directory as well and SILC Server Library will be created;
6064 sometimes in the future.
6066 * Removed Local commands from lib/silccore/silccommand.h as
6067 they are application specific and new client library does not
6068 handle any of those anymore.
6070 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6071 old client implementation in silc/.
6073 * Added support for callback functions in SILC_LOG_* macros.
6074 Application can now set its own callbacks that will be called
6075 instead of using the default functions that will always print
6076 the debug messages to stderr (or stdout). Also, debugging can
6077 now be disabled by setting silc_debug to FALSE and re-enabled by
6078 setting it to TRUE. Note, that logging will still work even
6079 if debugging is disabled.
6081 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6082 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6083 silc_log_reset_debug_callbacks.
6085 * To enable debugging in silc client one must give now -d
6086 option on command line.
6088 * Changed silc_schedule_init to automatically allocate task queues
6089 if they are not allocated before calling it.
6091 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Added GMP 3.1 into math library.
6095 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6098 a channel in SILC network. The packet is used by servers and
6099 routers to notify other routers that user has left a channel.
6100 This little feature was missing until now. Added the feature
6101 to protocol specification as well.
6103 Added functions: silc_server_send_remove_channel_user and
6104 silc_server_remove_channel_user into server.[ch].
6106 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6107 lib/silccore/silcpacket.h. However, they are not implemented
6110 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Fixed joining to a channel and sending channel messages
6113 between server and router. The channel message sending should
6114 now work inside a cell.
6116 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Fixed the private message sending between server and router.
6119 The private message sending should now work inside a cell.
6121 * Added silc_server_replace_id into server.[ch] to replace
6122 existing ID in the SILC network.
6124 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6125 and silc_idlist_replace_server_id into idlist.[ch] in server.
6127 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Fixed the server to server connections. Server can again now
6130 connect to router. Router to router connections probably does
6133 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Added dynamic protocol registering support. Now protocols can
6136 registered and unregistered on the fly. Patch by cras.
6138 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added lib/contrib directory to hold routines that some platforms
6141 don't have but are needed by SILC.
6143 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6144 into lin/contrib to provide getopt() and getopt_long() for
6145 those who don't have it.
6147 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Added AWAY command to client. When away message is set and
6150 client receives a private message packet the client automatically
6151 replies to the sender with the away message.
6153 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6154 bug seemed to be the cause of recent problems when compiling
6157 * Added version detection support to SKE protocol specification
6158 and added the new changes to the SKE implementation as well.
6159 There were other minor changes in the SKE protocol as well.
6161 Many changes in lib/silcske/silcske.[ch] and in
6162 lib/silcske/payload.[ch].
6164 * Added ^U functionality, clear input line. Patch from cras.
6166 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Mainly small bugfixes on core library. Fixed some debugging
6169 logging and buffer overflow in silclog.c.
6171 * Updated config.sub and config.guess on the distribution tree.
6173 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Added command lagging support in server. Client may execute
6176 commands now only once in two seconds.
6178 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Optimized packet reception. MAC computation and checking is now
6181 also more optimized. A lot previously duplicated code is now
6182 used as generic by both client and server.
6184 * Fixed key pair generation in clientutil.c
6186 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Added into lib/silccore/silcbufutil.[ch] new function;
6189 silc_buffer_realloc.
6191 * Moved generic packet sending/encryption functions to
6192 lib/silccore/silcpacket.[ch] from client and server. Some
6193 rewriting of the functions.
6195 * Moved all generic packet reception/decryption functions to
6196 lib/silccore/silcpacket.[ch] from client and server. The
6197 packet processing is now much cleaner in both client and server.
6198 These were major changes in both client and server.
6200 * Created many common functions in server to do packet sending.
6201 Previously code were duplicated a lot, this has been removed
6204 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Rewrote major parts of the ID cache system. Don't know
6207 whether it is better now or not but at least the API is more
6210 * Major rewrite on ID cache stuff on client because of the ID
6211 cache API changes. Added idlist.c to client.
6213 * Also major rewrite on ID cache stuff on server as well.
6214 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6215 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6216 in hand, instead they are all put into the ID cache system now.
6217 All server_idlist_* routines uses ID cache now instead of
6218 traversing its own lists (those lists does not exist anymore).
6219 SilcIDList though still exists. Also, SilcXXXEntry's are
6222 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Finally made the SKE implementation compliant to the protocol
6225 specification. All mp integers are now binary encoded as
6226 opposed being HEX encoded.
6228 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6231 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6232 functions: silc_[encode/decode]_pem. Also added function
6233 silc_encode_pem_file to PEM encode with newlines ('\n') for
6236 * SILC public keys are now encoded either PEM or binary. Same
6237 option is for private keys as well. By default private keys
6238 are binary encoded and public keys PEM encoded. Silly HEX
6239 encoding were removed.
6241 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6242 function to create fingerprints.
6244 * Fixed a bug in SHA1; does not change the original data anymore.
6246 * Partly implemented INFO command on client and server side.
6247 Fixed CLEAR command. Changes to SERVER command; show current
6248 server(s) when giving command without arguments. Added
6249 VERSION command to client.
6251 * Added check to server that unregistered connections cannot
6252 execute commands (unless it is specificly allowed).
6254 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Fixed screen refresh.
6258 * Fixed channel joining bug from client. On some circumstances
6259 client tried to join to a channel it had already joined.
6261 * Added public key verification process into client's protocol.c.
6262 The client now verifies the public key from user and saves
6263 it into ~./silc/serverkeys/ directory.
6265 Added into: clientutil.[ch]: silc_client_verify_server_key.
6267 * Changed SKE protocol's silc_ske_initiator_finish function
6268 to accept callback function that verifies the received public
6269 key. Removed old silc_ske_verify_public_key function.
6271 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6274 silc_pkcs_private_key[_data]_set.
6276 * Made the password and public authentication more cleaner in
6277 server's protocol.c.
6279 * Removed historic and obsolete protocol `channel_auth' from
6280 both client and server.
6282 * Removed wrong way of sending command status messages from
6283 server to client in server's command.c. The old way violated
6284 protocol specification.
6286 Changes to silccore/silccommand.[ch]: removed
6287 silc_command_encode_status_payload -> not needed anymore,
6288 changed silc_command_encode_payload_va to accept extra
6289 argument on variable argument list. The argument type must
6290 now be provided to the function. Also, added new function:
6291 silc_command_encode_reply_payload_va which is same as
6292 normal command_encode_payload_va except command status type
6293 is provided as extra argument.
6295 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6297 * Added ~./silc directory handling. The directory includes the
6298 public and private keys for the client.
6300 Added silc_client_check_silc_dir, silc_client_create_identifier
6301 and silc_client_load_keys.
6303 * Implemented SILC protocol compliant public key. Added public
6304 and private key saving to and loading from files.
6306 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6307 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6308 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6309 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6310 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6312 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6313 silc_pkcs_load_[public/private]_key.
6315 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Added silc_server_get_route (route.[ch]) to get connection
6318 data for the fastest route for given ID.
6320 * Implemented INVITE command on client and server. The command
6321 were re-defined in the SILC Protocol Specification and the
6322 implementation now complies with the specification.
6324 * Implemented PING command on client and server.
6326 * Implemented NAMES command on client and server. The server side
6327 supports currently only normal server not router server yet.
6328 Some changes to NAMES definition in SILC protocol specification.
6330 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Implemented LEAVE command on client and server.
6334 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6335 again. This change was made to the protocol as well. Server
6336 should not violate the protocol specification anymore.
6338 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6341 was tested. SOCKS4 was not but should work anyway.
