3 * Fixed LIST command reply sending in server. Affected file
6 * Server now sends the kicker's client ID in the KICK notify
7 to the kicked client. Affected file silcd/command.c.
9 * The client library now parses the kickers client ID and
10 UI displays it. Affected files lib/silcclient/client_notify.c
11 and irssi/src/silc/core/silc-channels.c, module-formats.c.
13 * Made all payload parsing function prototypes consistent.
14 They all take now const unsigned char * and uint32 pair as
15 the payload data instead of SilcBuffer. Changes all around
16 the source tree. Other unsigned char* -> const unsigned char*
17 changes around the tree as well.
19 * Optimized SFTP client and server packet sending not to
20 allocate new buffer for each packet but to recycle the
21 first allocated buffer. Affected files are
22 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
24 * Optimized the SFTP client to use SilcList instead of
25 SilcDList for requests, because it is faster. Affected file
26 is lib/silcsftp/sftp_client.c.
28 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
29 into lib/silccore/silcid.[ch].
31 Renamed silcpayload.[ch] into silcargument.[ch].
33 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
35 * If client entry is deleted with active key agreement
36 session, abort the session.
38 The silc_client_abort_key_agreement now calls the completion
39 callback with new SILC_KEY_AGREEMENT_ABORTED status.
41 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
44 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
46 * Don't use __restrict in older GCC's. Affected file is
47 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
49 * silc_net_localhost now attempts to reverse lookup the
50 IP/hostname. Affected file lib/silcutil/silcnet.c.
52 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
53 command. It can be used to gain founder privileges at
54 the same time when joining the channel.
56 Defined that the SILC_NOTIFY_TYPE_KICKED send the
57 kicker's client ID as well. Updated protocol specs.
59 Defined that the server must send SILC_COMMAND_IDENTIFY
60 command reply with error status to client who sent
61 private message with invalid client ID.
63 Updated the protocol specification.
65 * Added silc_server_send_command_reply to send any
66 command reply. Affected file silcd/packet_send.[ch].
68 * Added silc_id_payload_encode_data to encode ID payload
69 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
71 * The server now send IDENTIFY command reply with error
72 status if client ID in private message is invalid. Affected
73 file silcd/packet_receive.c.
75 * Save the server key file with server's IP address in
76 the filename instead of hostname. The affected file is
77 irssi/src/silc/core/client_ops.c.
79 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
81 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
84 * Added libtool support for compiling shared objects in
85 lib/silcsim. Affected file configure.in.pre and
86 lib/silcsim/Makefile.am. Original patch by cras.
88 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Pid file configuration, and server's config file fixes
91 patch by toma. Updated CREDITS file.
93 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Fixed silc_client_channel_message to not try to decrypt
96 the message twice if it resolved the destination client
97 information. This could cause of dropping one channel
98 message. Affected file lib/silcclient/client_channel.c.
100 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Added silc_client_run_one into lib/silcclient/silcapi.h and
103 lib/silcclient/client.c. This function is used when the SILC
104 Client is run under some other scheduler, or event loop or
105 main loop. On GUI applications, for example this may be
106 desired to used to run the client under the GUI application's
107 main loop. Typically the GUI application would register an
108 idle task that calls this function multiple times in a second
109 to quickly process the SILC specific data.
111 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
113 * Fixed silc_server_drop() for dropping the supplementary
114 groups as well, this could cause a security hole on some
117 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
119 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

123 to run server on foreground. A patch by debolaz.
124 Affected files silcd/server.c, silcd/silcd.c.
126 * Fixed MOTD to return the MOTD file server name. Affected
127 file silcd/command.c.
129 * Added INFO command reply handling to the Irssi SILC Client.
130 Affected file irssi/src/silc/core/client_ops.c.
132 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
134 * Fixed the silc_idcache_list_* routines to really support
135 the dynamic list. Fixes a crash. Affected file is
136 lib/silccore/silcidcache.c.
138 * Fixed the LIST command reply to really call LIST command's
139 pending callbacks. Affected file silcd/command_reply.c.
141 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Update conn->local_entry->nickname after giving NICK
144 command. Affected file lib/silcclient/command.c.
146 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
148 * Added the [pid] option to the silcd configuration file
150 Affected files: serverconfig.[ch] and silcd.c
152 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Save fingerprint in WHOIS command reply in server.
155 Affected file silcd/command_reply.c.
157 * Fixed NICK commands pending callback registration.
158 Affected file lib/silcclient/command.c.
160 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
162 * Use ++server->cmd_ident when sending commands in server,
163 instead of random number. Affected file silcd/command.c.
165 * Fixed GETKEY command reply to call actually GETKEY pending
166 command callbacks. Affected file silcd/command_reply.c.
168 * A bit stricter check for nicknames. Check for same nickname
169 in NICK command also. Affected file silcd/command.c.
171 * Do not call INFO command everytime client ID changes, only
172 during first connecting. Affected file lib/silcclient/client.c.
174 * Set the new nickname only after successful command reply for
175 NICK command is returned by server. Affected file
176 lib/silcclient/command.c.
178 * Remove nicknames from nicklist during server_signoff notify.
179 Should fix /NAMES bit more. The affected file is
180 irssi/src/silc/core/silc-channels.c.
182 * Added `fingerprint' field to the SilcIDListData in the
183 silcd/idlist.h to hold the fingerprint of the client's
186 Send the fingerprint of the client's public key in WHOIS
189 Affected files silcd/command.c, and silcd/idlist.[ch].
191 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
192 create fingerprint from given data.
194 * Show the fingerprint of the client's public key in WHOIS.
195 Affected files irssi/src/module-formats.[ch] and
196 irssi/src/silc/core/client_ops.c.
198 * Format the multiple same nicknames also during JOIN and
199 NICK_CHANGE notifys. Affected file is
200 lib/silcclient/client_notify.c.
202 * Do not print error on screen for invalid private message
203 payload since it can come if someone is sending private
204 messages with wrong key. Affected file
205 lib/silccore/silcprivate.c.
207 * Fixed multiple concurrent /PING crash. Affected file
208 lib/silcclient/command.c.
210 * Changed the wrong ID encoding. All IP addresses must be
211 in MSB first order in encoded format. They were encoded
212 wrong and was in LSB format. Affected files are
213 silcd/serverid.c, lib/silcutil/silcutil.c.
215 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
217 * Call the `connect' client operation through the scheduler
218 in case of error. Affected file lib/silcclient/client.c.
220 * Call the `failure' client operation even if the error
221 occurred locally during a protocol. Affected file is
222 lib/silcclient/protocol.c.
224 * Added support of sending LIST command to router from normal
225 server. This way normal server can get list of all channels
226 in the network too. Fixed the channel list sending in the
227 server too. Affected files are silcd/command.c, and
228 silcd/command_reply.[ch].
230 * Added silc_server_update_channels_by_server and
231 silc_server_remove_channels_by_server. They are used during
232 disconnection of primary router and in backup router protocol.
233 Affected file silcd/server_util.[ch], silcd/server.c and
234 silcd/server_backup.c.
236 * Fixed channel adding to global list in IDENTIFY command
237 reply in server. Affected file silcd/command_reply.c.
239 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
241 * If the incoming packet type is REKEY or REKEY_DONE process
242 that packet always synchronously. Fixes yet another MAC
243 failed error on slow (dialup) connections. Affected file
244 lib/silcclient/client.c and silcd/server.c.
246 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Call check_version SKE callback for initiator too. Affected
249 file lib/silcske/silcske.c.
251 * Implemented fix for security hole found in the SKE that was
252 fixed in the specification few days back; the initiator's
253 public key is now added to the HASH value computation.
254 Added backwards support for the old way of doing it too, for
255 old clients and old servers. Affected file is
256 lib/silcske/silcske.c.
258 * Enabled mutual authentication by default in SKE. If initiator
259 is not providing mutual authentication the responder will
260 force it. This will provide the proof of posession of the
261 private key for responder. The affected files are
262 lib/silcclient/protocol.c and silcd/protocol.c.
264 * Do not cache anymore the server's public key during SKE.
265 We do mutual authentication so the proof of posession of
266 private key is done, and if the server is authenticated in
267 conn auth protocol with public key we must have the public
268 key already. Affected file silcd/protocol.c.
270 * Added new global debug variable: silc_debug_hexdump. If
271 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
272 file lib/silcutil/silclog.[ch].
274 * Fixed compilation warning due to char * -> const char *.
275 Affected files lib/silcutil/silcnet.h, and
276 lib/silccore/silcauth.[ch].
278 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
280 * Fixed CMODE command when new channel key was created. If
281 the creation failed the old key was removed. Next time giving
282 same command would crash the server since the old key was
283 freed already. Affected file silcd/command.c.
285 * Fixed the silc_server_announce_get_channels to not crash
286 on reconnect. Affected file silcd/server.c.
288 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
290 * Added silc_log_set_debug_string function to set a regex
291 string to match for debug output. Only the function names,
292 or filenames matching the given debug string is actually
293 printed. This way it is possible to filter out those debug
294 strings that user is not interested in.
296 Fixed a bug in silc_string_regexify.
298 Affected files lib/silcutil/silclog.[ch], and
299 lib/silcutil/unix/silcunixutil.c.
301 * Changed the -d options in both server and Irssi SILC client
302 to take the debug string as argument. Affected files
303 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
305 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
307 * Added silc_hash_babbleprint to create a Bubble Babble
308 Encoded fingerprint. The encoding is developed by Antti
309 Huima (draft-huima-babble-01.txt), and it creates human
310 readable strings out of binary data. Affected file
311 lib/silccrypt/silchash.[ch].
313 * Print the babble print now in addition of fingerprint as well
314 in Irssi SILC client. Affected files are
315 irssi/src/fe-common/silc/module-formats.[ch],
316 irssi/src/fe-common/silc/core/client_ops.c.
318 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
320 * Fixed a security problem found in SKE. The initiator's
321 public key too is now added to the HASH hash value creation
322 which is signed by the responder to create the SIGN value.
323 This will prevent anyone in the middle to lie to the responder
324 about the initiator's public key. If this is done now, the
325 man in the middle will get caught. Updated the protocol
328 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Better installation directory handling. Configure module
331 paths and other paths automatically to example_silc* files
332 in doc/. A patch by toma.
334 * Fixed compiler warning from MPI library, and from SILC RNG.
337 * Added SILC_SERVER_PID_FILE to define the pid file for server.
338 It can be configured with ./configure. A patch by toma.
340 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
342 * Find correct make to use in prepare-clean. A patch by
343 toma. Affected file prepare-clean.
345 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
347 * Added irssi variables use_auto_addr, auto_bind_ip,
348 auto_bind_port and auto_public_ip.
350 * Changed the interface for silc_client_send_key_agreement
351 in lib/silcclient/silcapi.h
355 irssi/src/silc/core/silc-core.c
357 lib/silcclient/silcapi.h
358 irssi/src/silc/core/silc-channels.c
359 lib/silcclient/client_keyagr.c
362 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
364 * Added silc_pkcs_public_key_compare to compare two
365 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
367 * Check that the client who set the founder mode on the
368 channel is the same client that is giving the founder
369 mode to itself. It is done by comparing the saved public
370 key (it is saved even in the authentication is passphrase).
371 Affected file silcd/command.c.
373 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
375 * Do not process packet for disconnected socket connection.
376 Affected file lib/silccore/silcpacket.c.
378 * Process the DISCONNECT packet through scheduler in the
379 client library. Affected file lib/silcclient/client.c.
381 * Fixed the silc_client_packet_parse to not to increase
382 the packet sequence number if the conn->sock and the
383 current socket connection is not same. This can happen
384 for example during key agreement when the conn includes
385 multiple socket connections (listeners). Affected file
386 lib/silcclient/client.c.
388 * The sender of the file transfer request now provides also
389 the pointer (listener) for the key exchange protocol. If
390 the listener cannot be created then it sends empty key
391 agreement and lets the receiver provide the listener.
393 Added `local_ip' and `local_port' arguments to the
394 silc_client_file_send. If they are provided they are used,
395 if not then it will attempt to find local IP address, if
396 not found or bind fails then the remote client will provide
399 Affected files are lib/silcclient/client_ftp.c and
400 lib/silcclient/silcapi.h.
402 * Extended the FILE SEND command to support defining the
403 local IP and port for key exchange listener. They are
404 optional. Affected file irssi/src/silc/core/silc-servers.c.
406 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
408 * Defined to WHOIS command reply the sending of fingerprint
409 of the client's public key (if the proof of posession of the
410 corresponding private key is verified by the server).
411 Updated to the protocol specification.
413 * Added support of receiving the client's public key's
414 fingerprint in command reply in client library. Affected
415 file is lib/silcclient/command_reply.c, and
416 lib/silcclient/idlist.[ch].
418 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
420 * Do not send over 128 chars long nickname to the server
421 in NICK command. Affected file lib/silcclient/command.c.
423 * Do not send over 256 chars long channel names to the server
424 in JOIN command. Affected file lib/silcclient/command.c.
426 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Assure that silc_server_close_connection cannot be called
429 twice for same socket context. Affected file is
432 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
434 * Send error message to application if opening file for
435 writing during file transfer fails. Affected file is
436 lib/silcclient/client_ftp.c.
438 Remove all file transfer sessions for a client that we're
439 removing from ID cache.
441 Affected file is lib/silcclient/client_ftp.c.
443 * Fixed silc_net_addr2bin to return correct address. Affected
444 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
446 * Fixed file transfer session removing on signoff notify.
447 Affected file irssi/src/silc/core/silc-servers.c.
449 * Added the SilcClientFileError to be returned in the monitor
450 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
451 Affected file lib/silcclient/silcapi.h.
453 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
455 * Fixed a crash in silc_client_ftp_free_sessions and
456 silc_client_ftp_session_free_client. Affected file
457 lib/silcclient/client_ftp.c.
459 * Added `disabled' field in the SilcChannelEntry in the server
460 to indicate if the server entry is disabled. Affected file
461 silcd/idlist.h, silcd/command[_reply].c.
463 * SILC server adds now /var/run/silcd.pid everytime it is
464 started. Affected file silcd/silcd.c.
466 * Added silc_server_packet_send_clients to send a packet to
467 the provided table of client entries. Affected file
468 silcd/packet_send.[ch].
470 * Fixed a crash in client resolving in client_prvmsg.c in
471 client library. Affected file lib/silcclient/client_prvmsg.c.
473 * Do not actually remove the client directly from ID cache
474 during SERVER_SIGNOFF, but invalidate it. This way we
475 preserve the WHOWAS info for the client. Affected file
478 * Fixed SERVER_SIGNOFF notify handling in the server. The
479 server is now able to process incoming SERVER_SIGNOFF notify
480 for a server that it doesn't even know about. It will remove
481 the clients provided in the notify. Affected file
482 silcd/packet_receive.c.
484 * Check for partial packet in data queue after every packet that
485 was found from the queue. Return and wait for more data if
486 there is partial data in queue. Affected file is
487 lib/silccore/silcpacket.c.
489 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
491 * Added SilcClietFileError enum to indicate error in
492 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
493 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
494 Affected files lib/silcclient/silcapi.h and
495 lib/silcclient/client_ftp.c.
497 * Check that newsize in silc_buffer_realloc is larger than
498 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
500 * Added better monitor of file transfers. It now monitors
501 key agreement protocol during the file transfer too. Added
502 error reporting too. Affected files
503 irssi/src/silc/core/silc-servers.c,
504 irssi/src/fe-common/silc/module-formats.[ch].
506 * Wrote a help file for FILE command.
508 * Added silc_rng_global_get_byte_fast to get not-so-secure
509 random data as fast as possible. Random data is read from
510 /dev/urandom if available and from the SILC RNG if not
511 available. It is used in padding generation. Affected file
512 lib/silccrypt/silcrng.[ch].
514 * All packets in client library are now processed synchronously.
515 Optimized packet processing a lot. Affected file
516 lib/silcclient/client.c.
518 * All server connection packets are processing synchronously
519 now in server, to optimize packet processing. Affected file
522 * Include files are installed now only in Toolkit distribution
523 if make install is given. Affected files: all Makefile.am's.
525 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
527 * Assure that silc_client_notify_by_server_resolve does not
528 resolve the client information multiple times. If it cannot
529 be found by the first it cannot be found at all. Affected
530 file lib/silcclient/client_notify.c.
532 * Fixed WHOWAS command reply calling. Affected file
533 lib/silcclient/command_reply.c.
535 * Removed all references to silc_idlist_get_client from the
536 Irssi SILC client since that call is internal call used by
537 the library. The Irssi SILC client will use now client
538 retrieval functions found in silcapi.h.
540 * Fixed a bug in resolving nickname info before sending
541 private message. It used freed memory. Affected file
542 irssi/src/silc/core/silc-servers.c.
544 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Assure my_channels statistics cannot go negative in server.
547 Affected files silcd/server.c, silcd/server_util.c.
549 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
551 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
553 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
555 * Win32 Toolkit changes. Affected files
556 win32/silc.dsw, win32/libsilc/libsilc.def,
557 win32/libsilcclient/libsilc.def,
558 lib/silcutil/silcutil.c, and
559 lib/sftp/sftp_fs_memory.c.
561 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
563 * Added silc_net_localip to return local host's IP address.
564 Affected file lib/silcutil/silcnet.[ch].
566 * If key exchange or rekey protocol is active for a connection
567 parse all packets syncronously since there might be packets
568 in packet queue that we are not able to process without first
569 processing packets before them. Affected file silcd/server,

605 lib/silcutil/silcutil.[ch].
607 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Resolve the client info when received private message or
610 channel message for a client which nickname we don't know.
611 Affected files lib/silcclient/client_prvmsg.c and
612 lib/silcclient/client_channel.c.
614 * Do not crash in /KEY if client is not connected. Affected
615 file irssi/src/silc/core/silc-channels.c.
617 * Added SilcClientStatus field to the SilcClientEntry in the
618 lib/silcclient/idlist.h.
620 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
621 is incomplete and is being resolved, it won't be resolved
624 Make sure also that USERS command reply does not resolve
625 twice information. Affected file is
626 lib/silcclient/command_reply.c.
628 Make sure that silc_client_get_clients_by_list does not
629 resolve twice same information.
631 * Check for valid client->id in the silc_server_free_client_data.
632 Affected file silcd/server.c.
634 * Fixed /GETKEY nick@server not to crash if the server entry
635 is not found. Affected file lib/silcclient/command.c.

647 * Call the silc_server_udpate_servers_by_server in the
648 primary router that comes back online in the backup resuming
649 protocol. Otherwise it routes packets wrong. Affected file
650 silcd/server_util.[ch], silcd/server_backup.c.
652 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
654 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
655 lib/silcutil/silcbuffmt.[ch].
657 * Redefined the SILC packet header to include the padding
658 length. Affected file lib/silccore/silcpacket.[ch].
660 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
661 length for maximum padding up to 128 bytes). Affected
662 file lib/silccore/silcpacket.h.
664 * Removed all backwards support for old 0.5.x MAC thingies.
665 The SILC packet header change makes it impossible to be
666 backwards compatible.

669 protocol. This is to assure that all routers has connected
670 to the primary router. Affected file silcd/server_backup.c.
672 * Changed the RNG to take the first IV from random data. It
673 used to take it from zero actually. Changed the RNG also
674 to use /dev/urandom during session. /dev/random is used
675 in initialization. Affected file lib/silccrypt/silcrng.[ch].
677 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Changed the SILC packet header to have the first two bytes
680 (the packet length) encrypted. Affected files aroung the
681 code tree, lib/silccore/silcpacket.[ch]. Removed the
682 SilcPacketCheckDecrypt callback. It is not needed anymore
683 since the silc_packet_receive_process will determine now
684 whether the packet is normal or special.
686 * Implemented the unidirectional MAC keys. Affected files
687 lib/silcske/silcske.c, silcd/protocol.c and
688 lib/silcclient/protocol.c.
690 * Implemented the packet sequence number to the MAC computation.
691 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
692 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
693 lib/silcclient/protocol.c.
695 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Allow backup router to announce servers. All servers
698 announced by backup router are added to the global list
699 automatically. Update hte server's socket to our primary
700 router also when backup router announces a server.
701 Affected file silcd/packet_receive.c.
703 * Do not update the client->router in the function
704 silc_server_udpate_clients_by_server if the client is on
705 global list. We might fail to find any specific server
706 for locally connected clients and local cell clients. They
707 should still use the `from' and not `to' as client->router.
708 This fixes backup router resuming protocol. Affected file
711 * Decrease channel statistics count only if the channel
712 deletion worked. Affected files are silcd/server.c and
715 * Added silc_server_update_servers_by_server to update origin
716 of all server entries. Used during backup router protocol.
717 Affected files silcd/server_util.[ch], silcd/server.c. and
718 silcd/backup_router.c.
720 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
721 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
722 silc_hmac_get_hash and silc_hmac_get_name. Affected file
723 lib/silccrypt/silchmac.c.
725 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
727 * Assure that router cannot reroute the same channel message
728 to the sender. Affected file silcd/packet_receive.c.
730 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Made better checks that the channel message is not sent
733 to the router it came from. Affected file is
734 silcd/packet_send.c. Fixed memory leak too.
736 * Announce informations for incoming router connection, but
737 only after checking if it is replaced by backup router.
738 Affected file silcd/packet_receive.c.
740 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
742 * Fixed the backup resuming protocol to work in multiple
743 router environment. Affected file silcd/server_backup.c.
745 * Route packet only to one router in the function
746 silc_server_packet_send_to_channel. Affected file is
749 * Fixed silc_server_send_notify_dest to set the broadcast
750 flag. Fixed the silc_server_send_notify_topic to actually
751 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
752 Affected file silcd/packet_send.c.
754 * Changed the SFTP Filesystem interface. Changed the
755 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
756 the filesystem operation function. The SilcSFTPFilesystem
757 is now a context that is allocated by all filesystem allocation
758 functions and it already includes the operations structure
759 and filesystem specific context. It is given as argument
760 now to the silc_sftp_server_start. This made the interface
761 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
762 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
764 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
766 * Changed the backup router adding and getting interfaces
767 in the server. The router that will be replaced by the
768 specified backup router is now sent as argument. Affected
769 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
772 * Added silc_net_addr2bin_ne to return the binary form of
773 the IP address in network byte order. Affected files
774 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
776 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

790 protocol specification.
792 * Removed one redundant channel key generation from normal
793 server during joining procedure. Removed one redundant
794 channel key sending from server to router during joining
795 procedure. Affected file silcd/command.c.
797 * Made minor bugfixes to the backup router resuming protocol.
798 Affected file silcd/server_backup.c, server.c.
800 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

803 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
806 * Implemented the backup resuming protocol that is used to
807 resume the primary router position in the cell after the
808 primary router comes back online. Affected files
809 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
810 and silcd/server_util.[ch].

818 send any data. Affected file silcd/packet_send.c.
820 * Assure that if outgoing data buffer is pending do not force
821 send any data. Affected file lib/silcclient/client.c.
823 * Implemented the backup router support when the primary router
824 goes down. The servers and routers can now use the backup
825 router as new primary router without loosing connectivity.
827 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
830 in the server to indicate disabled entry. All data read
831 from the connection will be ignored and no data is sent
832 for entry that is disabled. Affected files are
833 silcd/idlist.h, silcd/server.c.
835 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Created SFTP client and server test programs in the
838 lib/silcsftp/tests directory.
840 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
842 * Implemented memory filesystem (virtual filesystem) for
843 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
846 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Implemented the SFTP (SSH File Transfer Protocol) to the
849 lib/silcsftp. It includes SFTP client and SFTP server
852 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
854 * Moved lib/silccore/silcprotocol.[ch] to the
855 lib/silcutil library.
857 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
858 take variable argument list pointer as argument. Affected
859 file lib/silcutil/silcbuffmt.[ch].
861 * Added silc_buffer_set function that is used to set data
862 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
863 Affected file lib/silcutil/silcbuffer.h.
865 * Changed various routines in the core library to use the new
866 silc_buffer_set instead of allocating new buffer only for
869 * Added 64-bit value formatting and unformatting support to the
870 silc_buffer_[un]format routines. Affected file is
871 lib/silcutil/silcbuffmt.[ch].
873 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
874 to includes/bitmove.h.
876 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
878 * Fixed channel user mode saving in client library. Affected
879 file lib/silcclient/command[_reply].c.
881 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Defined the file transfer to the SILC Protocol. Added
884 new packet type SILC_PACKET_FTP and defined File Transfer
885 Payload. The mandatory file transfer protocol is SFTP
886 (SSH File Transfer Protocol). Affected file in addition
887 of the internet draft is lib/silccore/silcpacket.h.
889 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
890 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
891 is used as part of backup router protocol when the primary
892 router of the cell is back online and wishes to resume
893 the position as primary router.
895 * Redefined the MAC generation keys in the protocol. The
896 same key is not used anymore in both direction. Both
897 direction will now use different keys for sending and
898 receiving. This fixes a potential security flaw. This
899 change causes incompatibilities in the protocol.
901 * Redefined also the MAC computation from the packet.
902 An packet sequence number is now added to the MAC
903 computation. This prevents possible replay attacks against
904 the protocol. This change too causes incompatibilities
907 Added `sequence' field to the SilcPacketContext to hold
908 the current sequence number for the packet.
910 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Added `created' field to the SilcIDListData in the file
913 silcd/idlist.h to indicate the time when the entry was
916 * Added `created' field to the SilcChannelEntry too. Affected
919 * Added `creation_time' aguments to all the announcement functions
920 in the server. If it is provided then only the entries that
921 was created after the provided time frame are actually
922 announced. Affected file silcd/server.[ch].
924 * The protocol says that the Channel ID's IP address must be
925 based on the router's IP address. Added check for this in
926 the silc_server_new_channel when processing incoming New Channel
927 Payload. Affected file silcd/packet_receive.c.
929 * Print out the correct version with --version in SILC client.
930 Affected file irssi/src/silc/core/silc-core.c.
932 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Fixed WHOWAS command to check for completnes of the client
935 entry always, not just when the command is coming from client.
936 Affected file silcd/command.c.
938 * Added new function silc_server_packet_queue_purge to purge the
939 outgoing data queue to the network. After the function returns
940 it is guaranteed that the outgoing packet queue is empty.
941 Affected file silcd/packet_send.[ch].
943 * Purge the outgoing packet queue in the rekey protocol's final
944 callback to assure that all rekey packets go to the network
945 before quitting the protocol. Affected file silcd/server.c.
947 * Added silc_client_packet_queue_parse as similar function as
948 in server to the client library. The affected file is
949 lib/silcclient/client.c.
951 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
953 * Splitted silcd/server.c and created silcd/server_util.[ch]
954 for utility functions.
956 * Added new socket flag SILC_SF_DISABLED to indicate that the
957 connection is open but nothing can be sent to or received from
958 the connection. Affected file lib/silcutil/silsockconn.[ch].
959 The checking for disabled socket is checked in the low level
960 silc_socket_write and silc_socket_read functions.
962 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Allow only nicknames and channel names that fits into the
965 7-bit unsigned char ASCII set. Affected file silcd/command.c.
967 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
969 * When processing JOIN command reply in server check that if
970 the channel exists in our global list we'll move it the local
971 list. Affected file silcd/command_reply.c.
973 * Fixed the check whether client is joined on the channel already
974 in JOIN command. Affected file lib/silcclient/command.c.
976 * Fixed the JOIN command reply to check whether the channel
977 already exists. Affected file lib/silcclient/command_reply.c.
979 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Added silc_ske_status_string to map the SKE error numbers
982 to readable strings. The affected files are
983 lib/silcske/silcske[_status].[ch].
985 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
987 * Do not show the private channels on the WHOIS channel list
988 as it is not allowed by the protocol. The affected file is
991 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Assure that the packet length digged from the actual packet
994 is something sensible in the silc_packet_decrypt_rest_special
995 in lib/silccrypt/silcpacket.c.
997 * Free and NULL the allocated pointer in silc_hmac_alloc if
998 the HMAC allocation fails. The affected file is
999 lib/silccrypt/silchmac.c.
1001 * Print the selected security properties to the log files in
1002 the server. Affected file silcd/protocol.c.
1004 * Add SKE's reference counter even if calling the completion
1005 callback manually. Otherwise it goes negative, although it
1006 does not cause any problems. The affected file is
1007 lib/silcske/silcske.c.
1009 * Remove the client entry with short timeout after giving the
1010 KILL command. Affected file lib/silcclient/command.c.
1012 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1013 case all found clients are already disconnected (WHOWAS would
1014 found them) in the server. Affected file silcd/command.c.
1016 * Update the last_receive (time of last data received) to be
1017 updated only when received private or channel message so that
1018 the idle time showed in WHOIS makes more sense.
1020 * Added boolean field `valid' in to the SilcClientEntry in the
1021 client library to indicate whether the entry is valid or not.
1022 This fixes the nickname change bug on channel when changing
1023 the nickname to be same than the old (like nick to Nick) the
1024 nickname formatter doesn't set the new nick anymore to Nick@host.
1025 Affected file lib/silcclient/idlist.[ch].
1027 * Now actually fixed the nickname changing on disconnection.
1028 Added new function silc_change_nick to the Irssi SILC Client.
1029 Affected file irssi/src/silc/core/client_ops.c,
1030 irssi/src/silc/core/silc-nicklist.[ch].
1032 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Check that the public key exists in the GETKEY command before
1035 trying to encode it. Affected file silcd/command.c.
1037 * Print some notifications on received public keys with GETKEY
1038 command in the Irssi SILC Client. Affected files are
1039 irssi/src/fe-common/silc/module-formats.[ch],
1040 irssi/src/silc/core/client_ops.c.
1042 * Use IDENTIFY command to resolve the server information in the
1043 GETKEY command instead of INFO command. Affected file
1044 lib/silcclient/command.c.
1046 * All command reply functions in the client library now calls
1047 the pending command reply callbacks even if an error has
1048 occurred. The server has done this a long time and now it was
1049 time to move the client library to this as well. Now all
1050 errors can be delivered back to the pending command reply
1051 callbacks if necessary. Affected files are
1052 lib/silcclient/command[_reply].[ch].
1054 * Change the nickname on disconnection back to the username
1055 because in reconnect the server will enforce it to it anyway.
1056 Affected file irssi/src/silc/core/silc-servers.c.
1058 * Fixed a config file parsing bug in the Irssi SILC client.
1059 Affected file irssi/src/silc/core/clientconfig.c.
1061 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * When printing the channel mode on JOIN, verify that the
1064 channel key and channel's HMAC are valid. Affected file
1065 irssi/src/silc/core/client_ops.c.
1067 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1070 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1071 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1073 * Removed channel key rekey task deleting from the function
1074 silc_server_save_channel_key. Affected file silcd/server.c.
1075 Added explicit timeout task context instead that is used to
1076 delete the task if we are registering a new task before the
1077 new task has elapsed.
1079 * When channel key rekey occurs the client library now saves
1080 the old channel key for a short period of time (10 seconds) and
1081 is able to use it in case some is still sending channel
1082 messages encrypted with the old key after the rekey. Affected
1083 file lib/silcclient/[idlist.h|client_channel.c].
1085 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Added check to the silc_server_new_id_real to not accept
1088 new ID if it is the sender's own ID. Affected file is
1089 silcd/packet_receive.c.
1091 * Assure that we do not announce ourself or the one we've
1092 sending our announcements when we're router and are announcing
1093 servers to our primary router. Affected file silcd/server.c.
1095 * Fixed silc_server_command_identify_check_client to assemble
1096 correct WHOIS packet. It send corrupted WHOIS packet and
1097 caused problem with router to router connections. Affected
1098 file silcd/command.c.
1100 Fixed also silc_server_command_whois_check the same way
1101 as for the IDENTIFY command.
1103 * Added new SilcIDListStatus to the server in the SilcIDListData
1104 structure. The status now includes the current status of
1105 the entry (like registered, resolved etc.). Affected file
1106 silcd/idlist.[ch]. Defined a bunch of different status types
1107 as well. This replaced the old boolean registered field as well.
1109 Added resolve_cmd_ident field to the SilcClientEntry structure
1110 too so that if the entry is for example being resolved so
1111 another command may attach to the same pending command reply
1112 without requiring to resolve the same entry again. This concept
1113 should optimize the WHOIS and the IDENTIFY resolving under
1114 heavy load by taking away unnecessary resolving for entries
1115 that are being resolved already.
1117 Added support for adding multiple pending commands for one
1118 command idenfier. Affected file silcd/command[_reply].[ch].
1120 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1121 before deleting the data. Otherwise the hash table will have
1122 freed data in comparison functions. Affected file is
1123 silcd/command_reply.c.
1125 * Fixed silc_idlist_replace_client_id to add the new entry to
1126 the cache with NULL nickname. Otherwise there will be invalid
1127 memory as the nickname after the nickname is freed. Affected
1128 file silcd/packet_receive.c.
1130 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1131 saved into wrong slots because the previous number of entries
1132 was not taken into account. Affected file silcd/idlist.c.
1133 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1135 * If we are router and we receive JOIN notify to a channel that
1136 does not have any users then notified client is marked as the
1137 channel founder, as it is it. The affected file is
1138 silcd/packet_receive.c
1140 * Added to the extended hash table API's table_del_*ext functions
1141 the destructor as argument too, so that the caller can decide
1142 which destructor to use or whether to use destructor at all.
1143 Affected file lib/silcutil/silchashtable.[ch].
1145 * Fixed ID Cache purging. It actually deleted the entries from
1146 the hash table after the data was freed. The hash table ended
1147 up comparing freed memory. The affected file is
1148 lib/silccore/silcidcache.c.
1150 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed Irssi SILC client's KILL command's HELP syntax.
1154 * The USERS command now resolves the detailed user information
1155 if the userinfo field is missing. Affected file is
1156 lib/silcclient/command_reply.c.
1158 * Do not print error in silc_file_read if the read file does
1159 not exist. Just silently return NULL. Affected file is
1160 lib/silcutil/silcutil.c.
1162 * Fixed the silc_log_output to not wine about NULL filename
1163 and to not create some bogus " " filename. Affected file is
1164 lib/silcutil/silclog.c.
1166 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Fixed various printing bugs on the user interface in the
1169 Irssi SILC Client. Minor changes that were forgotten from
1172 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Fixed the configure.in.pre and the compilation and distribution
1175 environment to support the new autoconf 2.52. That version is
1176 now required to compile the CVS trunk.
1178 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1181 to generally parse user@fqdn format strings. Affected file
1182 lib/silcutil/silcutil.c.
1184 * Added nickname_format and nickname_force_format fields to the
1185 SilcClientParams structure. The first one defines the format
1186 for the nicknames that the library will enforce if the receives
1187 multiple same nicknames. The second one is boolean value and
1188 can be used to force the library to always enforce the format
1189 to the nicknames regardles whether there are multiple nicknames
1190 or not. This configurable formatting was employed to flexibly
1191 support accessing multiple nicknames from the user interface.
1192 The userinterface can now set the nicknames to what ever format
1193 they prefer. Affected file lib/silcclient/silcapi.h.
1195 Added function silc_client_nickname_format to the file
1196 lib/silcclient/idlist.c. It performs the nickname formatting.
1198 Added new field `hostname´ to the SilcClientEntry context.
1199 It holds the hostname of the client. Affected file is
1200 lib/silcclient/idlist.h.
1202 * Irssi SILC Client sets the nicknames in nick@hostn format.
1203 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1204 irssi/src/silc/core/silc-core.c.
1206 The WHOIS printing now also shows both the real nickname and
1207 the formatted nickname so that user knows how to access the
1208 user if there are multiple same nicknames cached. Affected
1209 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1210 printing formatting too to take the hostname now as a separate
1211 argument. The Affected file is
1212 irssi/src/fe-common/silc/modules-formats.[ch].
1214 * Changed the silc_client_get_clients_local to accept the formatted
1215 nickname as argument. It accepts the real nickname too but the
1216 formatted nickname can be used to find the true entry from
1217 multiple entries. Affected file lib/silcclient/silcapi.h and
1218 lib/silcclient/idlist.c.
1220 * Added nickname_format_parse field to the SilcClientParams.
1221 It is a callback function provided by the application to parse
1222 the nickname out of the formatted nickname string. The library
1223 calls it to get the nickname from the formatted string. Since
1224 the application generally knows better the format of the nickname
1225 string it parses it instead of the library, even though library
1226 encodes the formatted string. If the callback function is not
1227 provided then the library will use the string as is. The
1228 affected file is lib/silcclient/silcapi.h.
1230 * All the nickname strings passed to the client library in
1231 commands are now expected to be formatted nickname strings.
1232 If the command does not support the formatted nickname string
1233 it will assume that the sent string is the actual nickname.
1234 Affected file lib/silcclient/command.c.
1236 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Added public key authentication support to OPER and SILCOPER
1239 commands in the client library. Affected file is
1240 lib/silcclient/command.c.
1242 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Changed the get_auth_methdod client operation to be asynchronous.
1245 It can be async if the application resolves the authentication
1246 method from the server during the negotiation. Added new
1247 SilcGetAuthMeth completion callback that the application will
1248 call after resolving the authentication method.
1250 Added function silc_client_request_authentication_method that
1251 the application can use to resolve the authentication method
1252 from the server. Added also SilcConnectionAuthRequest callback
1253 that the library will call after the server has replied. The
1254 application can call this function if it does not know the
1255 current authentication method.
1257 Affected files are lib/silcclient/client.c and
1258 lib/silcclient/silcapi.h.
1260 * The Irssi SILC client now automatically resolves the authentication
1261 method incase any configuration information is not present (and
1262 currently there never is). The affected file is
1263 irssi/src/silc/core/client_ops.c.
1265 * Fixed public key authentication from the client library.
1266 Affected file lib/silcclient/protocol.c. Changed also the
1267 protocol specification about the public key authentication in
1268 the connection authentication protocol. The actual data to be
1269 signed is now computed with a hash function before signing.
1271 * Fixed the public key authentication from the server as well.
1272 Affected file silcd/protocol.c.
1274 * Removed the mlock()'s from the memory allocation routines.
1275 Affected file lib/silcutil/silcmemory.c. The ./configure does
1276 not check anymore for the mlock(). Affected file is
1279 * Fixed USERS command in server to allow the execution of the
1280 command for private and secret channels if the client sending
1281 the command is on the channel. Affected file silcd/command.c.
1283 * Fixed silc_client_get_clients_local to return the clients
1284 count correctly. It could return wrong value. Affected file
1285 lib/silcclient/idlist.c.
1287 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1290 types. The assembler optimizations seemed not to like 64-bit
1291 data types. The assmebler optimizations thus are now enabled
1292 also for BSD systems as opposed to only enable them for Linux.
1294 * Do not check for threads at all on BSD systems. Affected
1295 file configure.in.pre.
1297 * Removed -n and -h options from the Irssi SILC Client since
1298 they are not used in silc.
1300 * Fixed the prime generation to assure that the first digit
1301 of the generated random number is not zero since our conversion
1302 routines does not like number strings that starts with zero
1303 digit. If zero digit is seen the random number is regenerated.
1304 This caused some corrupted RSA keys when the zero first digit
1305 was met. Affected file lib/silcmath/silcprimegen.c.
1307 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Fixed WIN32 configuration in the ./configure script.
1310 Fixed to include xti.h on environments that has it.
1311 Patches by Carsten Ilchmann and andrew.
1313 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Changed the silc_id_create_client_id to be collision
1316 resistant. It is now assured that there cannot be created
1317 two same client ID's. I suspect that some weird bugs in
1318 the server were actually caused by duplicate Client IDs.
1319 Affected file silcd/serverid.[ch]. A router receiving
1320 new ID now also assures and informs the sending server
1321 if the ID caused collision.
1323 * Changed the silc_id_create_channel_id to also assure that
1324 there are no collisions.
1326 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Statement about ignoring the Mutual Authentication flag when
1329 performing rekey with PFS was a bit misleading. It is ignored
1330 if it was set in the initial negotiation, it cannot be even
1331 set in the rekey. Fixed in the ke-auth draft. Started the
1332 new versions of the protocol drafts in the doc/.
1334 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Fixed a bug in silc_client_command_identify_save when saving
1337 new channel information. The channel name was no duplicated
1338 and caused crash on exit. Affected file is
1339 lib/silcclient/command_reply.c.
1341 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * Fixed the getkey command handling in the server. Send just
1344 empty OK reply to the sender if the key could not be fetched
1345 (but everything else was ok, like the key just was not available).
1346 Changed the public key parameter to optional in the protocol
1347 specs so that empty OK reply can be sent. Affected file
1350 Added a message to Irssi SILC client to tell to user if the
1351 server did not return a public key.
1353 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1355 * Fixed a channel key regeneration bug. It registered new
1356 timeout tasks exponentially until all system resources were
1357 used. Affected file silcd/server.c.
1359 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Added the SILC Document generator to the scripts/silcdoc.
1362 It can be used to generate the Toolkit Reference Manual out
1363 of the source tree. Internally it will also use the RoboDoc
1364 generator now imported in util/robodoc.
1366 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Added couple of return's in rekey protocol if error orccurred
1369 during the protocol. The execution must be terminated.
1370 Affected file silcd/protocol.c. Also, terminate the protocol
1371 always with timeout.
1373 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * The client's Client ID was created initally from the wrong
1376 nickname (it could have been in format nick@host) in the
1377 silc_server_new_client. Affected file silcd/packet_receive.c
1379 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Added some SILC_LOG_ERROR's to various error conditions
1382 if client could not be added to ID cache. Affected files
1383 silcd/packet_receive.c and silcd/server.c.
1385 * When client's sock->user_data is freed, NULL also the
1386 client->router and client->connection pointers. Added check
1387 for these pointers being NULL to various places around the
1388 code. Affected file silcd/server.c.
1390 * Added client->data.registered == TRUE checks to various
1391 places around the code to assure that unregistered client's
1392 are not handled when it is not allowed. Affected file
1395 * Added `bool registered' fields to all
1396 silc_idlist_[server|client]_get_* routines to indicate whether
1397 the fetched client needs to be registered or not. Affected
1398 file silcd/idlist.[ch].
1400 * Add your own entry as registered to the ID cache in the
1401 server. Affected file server.c.
1403 * Fixed a bug in silc_server_new_server. The SilcServer was
1404 set as the new server's context instead of SilcServerEntry.
1405 This naturally caused some weird bugs.
1407 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Do not delete the channel rekey task when adding it
1410 for in silc_server_create_channel_key.
1412 * Changed the silc_server_create_channel_key to return
1413 TRUE or FALSE to indicate the success of the channel key
1416 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Fixed MSVC++ project files and added missing files to
1419 Makefiles under win32/.
1421 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Do not add TCP_NODELAY flag if the operating system
1424 does not have it defined. Affected files are
1425 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1427 * Fixed buffer overflow from Irssi SILC Client. Affected
1428 file irssi/src/fe-common/core/themes.c.
1430 * Fixed double free in client library in the file
1431 lib/silcclient/client.c when disconnecting from server.
1433 * Applied double free patch from cras to Irssi SILC client.
1434 Affected files irssi/src/core/[modules/expandos].c
1436 * Fixed the disconnection handling to Irssi SILC Client.
1437 The application must call silc_client_close_connection
1438 in ops->connect client operation in case of failure of
1439 the connection. Affected file is
1440 irssi/src/silc/core/client_ops.c.
1442 * Do not set sock->protocol to NULL in the function
1443 silc_client_close_connection after executing the protocol's
1444 final callback since the sock might not be valid anymore.
1445 Affected file lib/silcclient/client.c.
1447 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Do not enable SILC_THREADS if the linking with libpthread
1450 did not happen. Affected file configure.in.pre.
1452 * Added notion to protocol specification that server must
1453 verify the sent authentication payload with CMODE when
1454 setting the channel founder key. Implemented it to the
1455 server. Affected file silcd/command.c.
1457 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Added _EXTRA_DIST SILC distribution variable to the
1460 distributions file. It is used to conditionally add extra
1461 files or directories to the specific distribution. Affected
1462 files ./prepare, Makefile.am.pre and distributions.
1464 Removed the `_' from the start of the distribution names.
1467 * Added README.WIN32 for instructions to compile the Toolkit
1470 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Fixed a double free in disconnection in the server. Affected
1473 file is silcd/server.c.
1475 * Fixed the lib/silcske/groups.c to work now also with GMP
1476 MP library. The string conversion did not work when using
1477 specific base and the base is indicated in the string as well.
1479 * Created win32/ directory which now includes MSVC++ specific
1480 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1481 It will appear only in the toolkit distribution
1483 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1485 * Changed the key material distribution function in case when
1486 the hash output is too short. The data is now concatenated
1487 a bit differently than it used to. Made the change to the
1488 SKE protocol specification.
1490 * Added better GMP detection to configure.in.pre. A patch
1493 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1495 * Fixed a minor bug in SKE that might cause some problem on
1496 some platforms. Affected file lib/silcske/silcske.c.
1498 * Added the cookie checking for initiator in the SKE. It checks
1499 that the responder returns the sent cookie unmodified. The
1500 affected file is lib/silcske/silcske.c. Added new SKE
1501 error type INVALID_COOKIE that can be sent during the
1502 negotiation. Fixed some memory leaks as well.
1504 * Added the "invalid cookie" error message to Irssi SILC client's
1507 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Added `task_max' field to the SilcClientParams to indicate
1510 the maximum tasks the scheduler can handle. If set to zero,
1511 default values are used. Affected file lib/silcclient/silcapi.h.
1513 * Fixed memory leaks in silc_client_close_connection. Affected
1514 file lib/silcclient/client.c.
1516 * Added silc_client_del_client_entry to client library to free
1517 all memory of given client entry. Affected file is
1518 lib/silcclient/idlist.[ch].
1520 * Added new functions silc_client_del_channel and
1521 silc_client_del_server to delete channel and server entries.
1522 Affected file lib/silcclient/[silcapi.h/idlist.c].
1524 * Removed silc_client_del_client_by_id from silcapi.h.
1526 * Fixed the INFO command to return the server's own info
1527 correctly when querying by Server ID. Affected file is
1530 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Removed the non-blocking settings in WIN32 code in the
1533 silc_sock_[read/write] and added SleepEx instead. Affected
1534 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1535 of input data is now checked with FIONREAD and ioctlsocket.
1537 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1539 * Call silc_schedule_task_del_by_context in the
1540 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1541 Affected file lib/silccore/silcprotocol.c.
1543 * Call silc_protocol_cancel for active protocols in the
1544 silc_server_close_connection if the funtion
1545 silc_server_free_sock_user_data has not been called.
1546 Affected file silcd/server.c.
1548 * Generic tasks cannot be deleted using the del_by_fd
1549 task deleting function since generic tasks does not match
1550 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1552 * Added a notion to SILCOPER help file that the SILCOPER works
1553 only on router server, not on normal server.
1555 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1557 * Added for WIN32 support for the new scheduler as well.
1558 Affected file lib/silcutil/win32/silcwin32schedule.c.
1560 * Fixed the SHA1 implementation to work on various platforms.
1562 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1565 API. It is part of the scheduler now. Everything else is
1566 as previously but some functions has changed their names.
1567 Checkout the lib/silcutil/silcschedule.h for the interface.
1568 Updated all applications to use the new interface. Affected
1569 files are lib/silcutil/silcschedule.[ch].
1571 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Found a bug in the SKE implementation. The HASH value,
1574 specified by the protocol, was not computed correctly. The
1575 public key of the responder was not added to the computation
1576 even though it is mandatory. Affected file lib/silcske/silcske.c.
1577 This unfortunately causes incompatibilities with older
1578 clients and servers.
1580 * Added WIN32 specific network init and uninit functions:
1581 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1582 the Winsock2. Affected file lib/silcutil/silcnet.h and
1583 lib/silcutil/win32/silcwin32net.c.
1585 * Set the socket always to nonblocking mode on WIN32 after
1586 reading data or writing data. Affected file is
1587 lib/silcutil/win32/silcwin32sockconn.c.
1589 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Fixed various compilation problems under WIN32. Affected
1592 files lib/silcutil/win32/silcwin32thread.c and
1593 lib/silcutil/win32/silcwin32schedule.c.
1595 * Removed all _internal.h #includes from public header
1596 files. Internal headers must never be included from
1599 Removed also the lib/silcske/payload_internal.h file.
1601 * All include files that may be needed (public and some others
1602 included by the public headers) by application developers are
1603 now copied to the ./includes directory. It does not copy any
1604 internal headers. Affected file Makefile.defines.pre and all
1605 Makefile.am's under lib/ and subdirs.
1607 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Do not change the ~/.silc directory's permissions automatically.
1610 Affected file irssi/src/silc/core/clientutil.c.
1612 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Do not cancel the protocol in silc_server_close_connection
1615 it might cause recursion. Now cancelled in the function
1616 silc_server_free_sock_user_data. Affected file silcd/server.c.
1618 * Fixed the silc_server_remove_clients_by_server to regenerate
1619 the channel keys correctly finally. Added also new function
1620 silc_server_remove_clients_channels to actually do it.
1621 Affected file silcd/server.c.
1623 * Fixed the silc_server_new_channel to not crash by giving
1624 wrong router to the new channel. Affected file is
1625 silcd/packet_receive.c.
1627 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1630 which is given as argument to the silc_client_alloc now.
1631 It can be used to configure the client and set various parameters
1632 that affect the function of the client.
1634 * The USERS command in server did not check whether the channel
1635 is private or secret. Affected file silcd/command.c.
1637 * Added new argument to the USERS command in protocol specification.
1638 The USERS command now can take the channel name as argument
1639 as well. Added support for this in client and server and
1640 updated the protocol specs.
1642 * Completed the GETKEY command in client. It can be now used
1643 to fetch also servers public key not only some clients.
1644 Affected files lib/silcclient/command[_reply].c.
1646 * Added silc_client_get_server to return server entry by the
1647 server name. Affected files lib/silcclient/silcapi.h and
1650 * Redefined the IDENTIFY command in protocol specification to be
1651 more generic. It now can be used to query information about
1652 any entity in the SILC Network, including clients, servers and
1653 channels. The query may be based either the entity's name
1654 or the ID. Added support for this in both client and server.
1656 Affected files silcd/command.c and lib/silcclient/command.c
1657 and command_reply.c.
1659 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1660 the _from_client and _from_server functions. Affected file
1663 * Added silc_client_get_channel_by_id_resolve to the file
1664 lib/silcclient/silcapi.h to resolve channel information by
1665 its ID. Added also silc_client_get_channel_by_id that
1666 does not resolve it from the server.
1668 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Added SilcServerEntry context into the client library
1671 to represent one server. The INFO command now allocates
1672 these to save the resolved server info. For now on the
1673 client library will also keep information about servers,
1674 connected and resolved with INFO.
1676 The INFO command now allocates the SilcServerEntry context
1677 and saves the server info there. The COMMAND_REPLY in
1678 the INFO now returns the parameters to application in
1679 same order as defined in the protocol specification.
1681 The entries are cached in the client->server_cache.
1683 * The INFO command is now issued after received the Client ID
1684 from the server. Affected file lib/silcclient/client.c.
1686 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1687 to the application as the mode changer might be server.
1688 It is guaranteed that NULL is not returned anymore to the
1689 application. Affected file lib/silcclient/client_notify.c.
1691 The ID Type is now also passed to the application so that
1692 it can check whether the returned entry is SilcClientEntry
1695 Added new function silc_client_get_server_by_id to return
1696 the server entry by ID. Affected files are the
1697 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1699 * Do not create the channel in the Irssi SILC Client when issuing
1700 the JOIN command but when received the sucessful JOIN command
1701 reply. Otherwise the channel might get created even though we
1702 could not join it. The Affected file is
1703 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1705 * Fixed a channel joining bug in router. The router must also
1706 check the channel modes, invite and ban lists etc. when serving
1707 the JOIN command sent by normal server. Affected file is
1708 silcd/command.c. The router now resolves the client's
1709 information from the server who sent the JOIN command if it
1710 does not know it, and processes the JOIN command only after
1713 * Changed the SilcCommandCb to take new argument; void *context2.
1714 Affected file lib/silccore/silccommand.h
1716 The second argument in the command callbacks in the server now
1717 includes the SilcServerCommandReplyContext if the command was
1718 called as pending command callback from the command reply.
1719 Otherwise it is NULL. When called as pending the status of the
1720 command reply will be checked and if it was erronous the
1721 error will be sent to the original sender of the command.
1722 This way the client always receives the error messages even
1723 though the server was actually the one who received the error
1724 when it resent the command to router, for example. Affected
1725 files silcd/command[_reply].[ch].
1727 * Fixed sending WHOWAS command's error message to client if
1728 the requested client could not be found. It was missing.
1731 * Changed the CMODE and CUMODE commands reply arguments in the
1732 protocol specification. The Channel ID is now sent in both
1733 of the commands to identify the channel. Implemented this
1734 new feature to the client and server. Affected files
1735 lib/silcclient/command_reply.c and silcd/command.c.
1737 * Made better checks for invite and ban lists in the JOIN
1738 command in server. Affected file silcd/command.c.
1740 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * The server now performs the incoming host IP/DNS lookup
1743 using the silc_socket_host_lookup and thus does not block
1744 the server anymore. Affected file silcd/server.c.
1746 * Completed the multi-thread support for SILC Scheduler in
1747 the lib/silcutil/silcschedule.c.
1749 * Fixed the configure.in.pre to detect the pthread correctly
1752 * Fixed a deadlock in silc_task_queue_wakeup in the file
1753 lib/silcutil/silctask.c.
1755 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Added new function silc_schedule_wakeup that is used in
1758 multi-threaded environment to wakeup the main thread's
1759 schduler. It needs to be used when a thread adds a new task
1760 or removes a task from task queues. After waking up, the
1761 scheduler will detect the task queue changes. If threads
1762 support is not compiled in this function has no effect.
1763 Implemented the wakeup mechanism to both Unix and WIN32
1764 systems. Affected files are lib/silcutil/silcschedule.[ch],
1765 lib/silcutil/unix/silcunixschedule.c and the
1766 lib/silcutil/win32/silcwin32schedule.c.
1768 * Added new function silc_task_queue_wakeup to wakeup the
1769 scheduler by the specified task queue. Affected file
1770 lib/silcutil/silctask.[ch].
1772 * The silc_socket_host_lookup_start now wakes up the scheduler
1773 after adding the timeout task. Affected file is
1774 lib/silcutil/silcsockconn.c.
1776 * The silc_socket_host_lookup is synchronous now if the threads
1777 support is not compiled in. However, the callback is still
1778 called asyncronously through the scheduler, anyway. Affected
1779 file lib/silcutil/silcsockconn.c.
1781 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Added new function silc_socket_host_lookup to perform
1784 asynchronous IP and FQDN lookups for the socket connection.
1785 Affected files lib/silcutil/silcsockconn.[ch].
1787 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1790 that may or may not compile the mutex support in.
1792 Changed the silc_mutex_alloc interface. It allocates the
1793 mutex now to the sent pointer and returns TRUE or FALSE.
1795 Affected file lib/silcutil/silcmutex.h.
1797 * Wrote the SILC Task Queue interface to support multi-threads.
1798 Affected file lib/silcutil/silctask.[ch].
1800 * Wrote the SILC Scheduler to support multi-threads. Affected
1801 file lib/silcutil/silcschedule.c.
1803 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1806 in lib/silcutil/win32/.
1808 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Defined SILC Mutex API and SILC Thread API and implemented
1811 them for Unix. Affected files are
1812 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1813 lib/silcutil/unix/silcunixmutex.c and
1814 lib/silcutil/unix/silcunixthread.c.
1816 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Fixed the silc_server_remove_clients_by_server's channel
1819 key re-generation. The hash table handling was incorrect
1820 and would not work with many channels. Affected file is
1823 * Fixed some memory leaks around the server code.
1825 * Rewrote the silc_server_get_users_on_channel to support IPv6
1826 based Client ID's. Affected file silcd/server.c.
1828 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1829 specification. However, a separate document must be written
1830 to define the detailed signing procedure and the payload
1831 associated with the flag. Defined the flag to the
1832 lib/silccore/silcchannel.h as well.
1834 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Changed the dynamic tables to static size tables in the
1837 lib/silccrypt/silchmac.c.
1839 * Removed GCC dependencies from the code. A patch by cras.
1841 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Do not show the error "Error receiving packet bla bla"
1844 in server if it really was not an error (-2 means that reading
1845 is pending). Affected file silcd/server.c.
1847 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Fixed a possible crash in silc_server_remove_clients_by_server
1850 in silcd/server.c. Fixed there also some memory leaks.
1852 * Fixed the silc_idlist_replace_client_id. It could replace
1853 wrong key in the hash table. Affected file silcd/idlist.c.
1855 * Do not check whether there are global users on the channel
1856 if the channel->global_users is FALSE. Affected functions
1857 silc_server_remove_from_one_channel and
1858 silc_server_remove_from_channels in silcd/server.c. Also,
1859 do not check if the removed client is local as we can be
1860 sure that global client was not removed from the channel
1861 and checking for global users is not needed.
1863 * The silc_server_remove_clients_by_server now re-generates
1864 the channel keys correctly for those channels that had
1865 clients removed from them. Affected file silcd/server.c.
1867 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Found the reason of random crashes in the server. We weren't
1870 ignoring the SIGPIPE signal (which can be sent in write())
1871 and it crashed the server. Affected file silcd/silcd.c.
1873 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Assure that sock->user_data is not NULL in the function
1876 silc_server_packet_send in silcd/packet_send.c.
1878 * Disconnect the remote connection if it could not be added
1879 to any ID lists in the server. The affected file is
1882 * Check in silc_server_packet_send[_real/dest] that the
1883 socket is not disconnecting and ignore the data if it is.
1884 Affected file silcd/packet_send.c.
1886 * Define inline to __inline on native WIN32 compilation.
1887 Affected file includes/silcwin32.h.
1889 * Added some explicit type casts for inline code since MSVC
1890 require them. Affected files lib/silcutil/silcbuffer.h,
1891 lib/trq/silcdlist.h and lib/trq/silclist.h.
1893 * Print warning in log files from now on if the packet
1894 decryption fails. Affected file silcd/server.c.
1896 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Changed the `say' client operation's interface to accept
1899 new `type' argument to indicate the type of the message sent
1900 by the library. The application may filter the library's
1901 messages according the type. The affected file is the
1902 lib/silcclient/silcapi.h.
1904 * Added two new functions to lib/silcclient/silcapi.h:
1905 silc_client_del_client and silc_client_del_client_by_id.
1906 Affected file lib/silcclient/idlist.c.
1908 * Moved the clientincludes.h from includes/ to silc/ and
1909 serverincludes.h from includes/ to silcd/.
1911 * The modes for the CMODE and CUMODE are now passed as
1912 uint32 for application with COMMAND_REPLY. The affected
1913 file is lib/silcclient/command_reply.c.
1915 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * /WHOIS without arguments shows client's own information.
1918 Affected file lib/silcclient/command.c.
1920 * Changed PING to not accept any arguments. The specs
1921 says that client can ping only the connected server so
1922 requiring an argument is not needed. Affected file is
1923 lib/silcclient/command.c.
1925 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Fixed a fatal bug in private message sending and reception
1928 encryption and decryption when using private message keys.
1929 The implementation was incorrect and did not follow the
1930 specification. It causd that some of the message were
1931 lost since it did not use the sending and receiving keys
1932 as the protocol suggests. This has been fixed and will cause
1933 incompatibilities with older clients when sending private
1934 message encrypted with private message keys. Affected files
1935 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1936 and various other in Irssi SILC Client.
1938 Added `responder' boolean argument to the functions
1939 silc_client_add_private_message_key[_ske] to indicate when
1940 the key is added as responder or initiator of the key
1943 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Removed the silc_ske_check_version function and created
1946 a SilcSKECheckVersion callback. Added also a function
1947 silc_ske_set_callbacks that is now used to set all SKE
1948 callbacks. The callback functions are not given to
1949 the SKE functions anymore, but this function is used to
1952 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1954 * Added `silc_version' argument to the silc_client_alloc
1955 to define the version of the application for the library.
1956 The library will use the version string to compare it
1957 against the remote host's (usually a server) version
1958 string. Affected file lib/silcclient/silcapi.h
1960 * Added the KE protocol context to Key Agreement context
1961 in client library so that we can abort the SKE if it
1962 is in process when we get timeout. Affected file is
1963 lib/silcclient/client_keyagr.c.
1965 * Do not resolve the client ID forever if it returns in the
1966 first time that such client does not exist. This was done
1967 for example with private message. Affected file is
1968 lib/silcclient/client_prvmsg.c.
1970 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Do not add regex.h for WIN32. The affected file
1973 includes/silcincludes.h.
1975 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1976 not work yet 100%. It generates the DLL's automatically
1977 when compiling with --with-win32 under cygwin.
1979 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * lib/contrib/regex.c is not compiled on WIN32.
1983 * Added silc_net_get_socket_opt function to the
1984 lib/silcutil/silcnet.h.
1986 * Added includes/silcwin32.h for WIN32 specific includes
1989 * Do not use ptime structure or any of the posix process
1990 functions on WIN32 in lib/silccrypt/silrng.c.
1992 * Added silc_gettimeofday to provide generic function
1993 for struct timeval on all platforms. Added the function
1994 to lib/silcutil/silcutil.h.
1996 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1998 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1999 library as they clearly belong there. As a plus side we
2000 can make the actual socket connection routines platform
2003 Added also new generic function silc_socket_read and
2004 silc_socket_write (that used to be silc_packet_[read/write].
2005 The implementation of these are platform specific.
2007 * Added WIN32 specific routines of silc_socket_[read/write]
2008 to lib/silcutil/win32/silcwin32sockconn.c.
2010 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Added preliminary support for native WIN32 compilation under
2013 cygwin (using the -mno-cygwin option for GCC) to the
2014 ./configure.in.pre. The --with-win32 now prepares the
2015 compilation for native WIN32.
2017 * Rewrote the SILC Scheduler interface in the file
2018 lib/silcutil/silcschedule.h. The scheduler is now context
2019 based and does not have anymore any global static scheduler.
2020 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2021 and created lib/silcutil/win32 directory for WIN32 based
2024 * Added Unix specific network routines to the
2025 lib/silcutil/unix/silcunixnet.c and the old
2026 lib/silcutil/silcnet.c includes now only generic routines.
2028 Added WIN32 specific network routines to the
2029 lib/silcutil/win32/silcwin32net.c.
2031 * Added Unix specific utility functions from the
2032 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2034 * Added WIN32 SILC Scheduler to the file
2035 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2038 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Do not handle JOIN notify in the server if the target client
2041 is not registered (idata->registered == FALSE). The affected
2042 file is silcd/packet_receive.c.
2044 * Update the nickrec->founder in event_cumode in the Irssi SILC
2045 client. Affected file irssi/src/silc/core/silc-channels.c.
2047 * Fixed the CUMODE_CHANGE notify handling in the server when
2048 server and router are announcing their clients on channels.
2049 Now the mode changes are saved and notified correctly. The
2050 affected file is /silcd/packet_receive.c.
2052 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2053 They really did not replace the cache entry in the ID Cache.
2054 Now they do that. Affected file silcd/idlist.c.
2056 * Fixed the KICK notify handling in the Irssi SILC client to
2057 update the channel records so that the kicked client does not
2058 appear to be on the channel. The affected file is
2059 irssi/src/silc/core/silc-channels.c.
2061 * Always update the conn->current_channel when executing command
2062 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2064 * Fixed the KILL notify handling in Irssi SILC client to remove
2065 the killed client on all channels.
2067 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Fixed the silc_parse_command_line to remove extra spaces
2070 from the start and end of the arguments. Affected file is
2071 lib/silcutil/silcutil.c.
2073 * Cancel and free any active protocol in the function
2074 silc_server_close_connection. Affected file silcd/server.c.
2076 * Cancel and free any active protocol in the function
2077 silc_client_close_connction. Affected file is
2078 lib/silcclient/client.c.
2080 * Do not execute the KILL command for clients that are in
2081 history (ie. they are not in the network). Affected file is
2084 * Fixed KILL notify handling, client does not crash anymore.
2085 Affected file irssi/src/silc/core/silc-channels.c.
2087 * Reduced the default packet buffer size from 2048 to 1024 in
2088 lib/silccore/silcpacket.c.
2090 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2091 counter to the SKE context that is incresed when the SKE library
2092 performs async operation outside the library. If the outside
2093 process frees the SKE context and FREED status will be set
2094 and the library will detect after the sync operation that the
2095 libary is freed. The affected files are
2096 lib/silcske/silcske[_status].[ch].
2098 * Resolve the client entry information in the function
2099 silc_client_channel_message to assure that NULL pointer is not
2100 passed as client entry to the application. */
2102 * Fixed the task timeout calculation to assure that there is
2103 never negative timeouts. The affected file is
2104 lib/silcutil/silcschedule.c.
2106 * Fixed the channel user mode notification sending in server.
2107 It was sent point-to-point to the router (or to server by router)
2108 but it needs to be destined to a channel. The routines now
2109 supports sending the channel user mode notifys to the channels
2110 when announcing clients and channels. Affected files are
2111 silcd/server.c and silcd/packet_receive.c.
2113 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2114 It did not actually replace the old channel entry in the cache.
2115 Affected file lib/silcclient/client_notify.c.
2117 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Fixed a possible crash in silc_packet_send_prepare. It now
2120 assures always that there is enough space in the buffer and
2121 at the tail area of the buffer (for MAC).
2123 Fixed the inbound buffer reallocation in silc_packet_read.
2124 It was old code and did not handle the reallocation correctly.
2127 The affected file is lib/silccore/silcpacket.c.
2129 * Fixed buffer overflow in silc_parse_nickname in the file
2130 lib/silcutil/silcutil.c.
2132 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * make install generates new server keys only if there is not
2137 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2140 Added check that if the NOREPLY is set then we will not send
2141 the away message. This avoids infinite loop of away messages
2142 if both clients are away. The affected file is
2143 lib/silcclient/client_prvmsg.c.
2145 * Fixed client crash if /NICK was given without arguments.
2146 Affected file lib/silcclient/command.c.
2148 * Server does not send the invite list in INVITE command back
2149 to the client if the list was not altered. Added this notion
2150 to the protocol spec as well. Affected file silcd/command.c.
2152 Fixed possible crash in INVITE command by checking the
2153 value of silc_server_get_client_route command.
2155 * Fixed the INVITE notify type handling. The arguments are now
2156 taken in correct order and client does not crash. The affected
2157 file is irssi/src/silc/core/silc-channels.c.
2159 Removed the "Inviting xxx to channel" message from the
2160 client library away and let the application handle it.
2161 Affected file lib/silcclient/command.c. Added that message
2162 to Irssi SILC client's message formats.
2164 * Fixed CMODE command crash in client. It now checks the
2165 amount of arguments correctly and does not crash. The affected
2166 file is lib/silcclient/command.c.
2168 * Do not create new channel automatically in silc_channels_join
2169 but check whether the channel by that name already exists.
2170 Affected file irssi/silc/core/silc-channels.c.
2172 * Do not send the SERVER_SIGNOFF to router if the disconnected
2173 entity was the router. Affected file silcd/server.c.
2175 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2176 SILC client as it was missing from there.
2178 Added the handling of the KICK notify to the Irssi SILC client
2179 as it was missing. Added "you have been kicked" message to
2180 Irssi SILC client's message modules formats.
2182 Added the handing of the KILL notify to the Irssi SILC client
2183 as it was missing. Added the kill message module formats
2186 The affected file is irssi/src/silc/core/silc-channels.c.
2188 * The router did not save the channel mode the server announced.
2189 Affected file silcd/packet_receive.c.
2191 * Fixed a possible crash in INFO command in server. If the
2192 server did not provide the server info it crashed. Affected
2193 file silcd/command.c.
2195 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Fixed the GETKEY command in the server to check also the
2198 global list. Otherwise the GETKEY would not work correctly
2199 in normal SILC server. Affected file silcd/command.c.
2201 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Fixed GETKEY crash, it crashed if the command did not succseed.
2205 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2208 is now real and not just an macro interface to GMP.
2210 Removed the entire GMP from the source tree and imported new
2211 NSS MPI library instead. Reason for removing GMP is that it is
2212 extremely large and compiles extremely slow. The NSS MPI
2213 is only a few files and compiles in less than 10 seconds.
2214 The speed is also about the same as GMP. The MPI is imported
2215 to lib/silcmath/mpi.
2217 If the system has GMP installed we will still use the GMP.
2218 If it is not then the NSS MPI will be compiled.
2220 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Merged a long nickname (127 characters long) crash bugfix from
2223 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2225 * Merged a freed memory reference bugfix from Irssi CVS tree.
2226 Affected file irssi/src/core/commands.c.
2228 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Added the server's public key sving and verification to the
2231 server when performing the SKE. This was missing and the
2232 remote server's (or router's) public key was accepted without
2233 checking whether we have it previously or trust it at all.
2234 Affected file silcd/protocol.c.
2236 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * Check in the silc_server_timeout_remote if protocol is active
2239 and make sure that the protocol's final callback is called so
2240 that all memory if freed. Affected file silcd/server.c.
2242 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * silc_server_whois_send_reply crashed the server if the nickname
2245 was 127 characters long. Affected file silcd/command.c.
2247 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Added sanity check to the silc_server_new_client. If the hostname
2250 is provided inside username then check that the provided hostname
2251 really is the same as the resolved one. If the hostname was not
2252 resolved then check it from the public key. Affected file is
2253 silcd/packet_receive.c.
2255 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2256 if the server disconnected us and the connection is not valid
2257 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2259 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2260 the library to the lib/silcutil/silcutil.[ch].
2262 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Close log file after open. Affected file
2265 lib/silcutil/silclog.c.
2267 * Check whether sock == NULL in silc_client_send_packet and return
2268 if it is. Affected file lib/silcclient/silcclient.c.
2270 * Check rec->entry == NULL in the Irssi SILC Client before
2271 sending the channel message. Affecte file is
2272 irssi/src/silc/core/silc-servers.c.
2274 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Merged a splitted window bugfix from Irssi CVS tree. The
2277 affected file is irssi/src/fe-text/textbuffer-view.c.
2279 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2280 It did not print nickname.
2282 * Improved the distributions system a bit.
2284 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2287 irssi/src/fe-text/gui-window.c.
2289 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2290 to in-active server. The affected file is
2291 irssi/src/silc/core/client_ops.c.
2293 * Resolve the client in USERS command reply if the entry does
2294 not have username resolved. The affected file is
2295 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2296 command to WHOIS command to really resolve stuff. The USERS
2297 is not used any more in any critical section so WHOIS can
2298 be used even though it might be slower than IDENTIFY.
2300 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2303 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Changed the protocol API a bit more consistent in the
2306 lib/silccore/silcprotocol.[ch].
2308 * Changed the following headers to ROBODoc format:
2310 lib/silccore/silcpayload.h
2311 lib/silccore/silcprotocol.h
2312 lib/silccore/silcsockconn.h
2314 All core library headers are now formatted.
2316 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Fixed a bug in Irssi SILC client; do not show that you are
2319 server/router operator if you really are not. Affected file is
2320 irssi/src/silc/core/client_ops.c.
2322 * Renamed silc_command_free_payload to silc_command_payload_free.
2323 Affected file lib/silccore/silccommand.h
2325 * Added silcmath.h to include the prototoypes of various routines
2326 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2329 * Changed the following headers to ROBODoc format:
2331 lib/silccore/silcchannel.h
2332 lib/silccore/silccommand.h
2333 lib/silccore/silcid.h
2334 lib/silccore/silcidcache.h
2335 lib/silccore/silcmode.h
2336 lib/silccore/silcnotify.h
2337 lib/silccore/silcpacket.h
2338 lib/silcmath/silcmath.h
2340 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Added checking to the server code not to start the server if
2343 ciphers and stuff are not configured properly. Affected files
2344 silcd/serverconfig.[h] and silcd/server.c.
2346 * Changed the layout of the header files of the public interfaces
2347 in the SILC libraries. The new layout supports ROBODoc
2348 documentation tool (and some others) so that it is easy to create
2349 a library reference manual. All the other headers and source
2350 code must still follow the CodingStyle document. Also source
2351 code must not include these ROBODoc stuffs, only the headers.
2352 Furthermore, all public interface headers must now be named
2353 by using `silc' prefix, example: silcapi.h, silccipher.h.
2354 Some files were renamed due to this. All the other headers
2355 must not be used as public interfaces. I will update the
2356 CodingStyle document later. Changed following headers, so far:
2358 lib/silcclient/silcapi.h
2359 lib/silccore/silcauth.h
2360 lib/silccore/silcprivate.h
2361 lib/silccrypt/silcdh.h
2363 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Removed silc_client_packet_send_flush from the client library
2368 as it is not needed. Affected file lib/silcclient/client.[ch].
2370 * Added printing of message of unresolved authentication method
2371 to the Irssi SILC client. Added it to the module formats.
2372 Removed the same message from the client library.
2374 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Added new distribution feature, DISTLABEL. Every distribution
2377 can define own preprocessor label that can be used in the
2378 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2379 file distributions, acconfig.h.pre and prepare.
2381 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * Added Makefile.defines_int to include the actual definitions
2384 for Makefile.defines.in. Tested the new distribution system,
2385 created distributions and tested installation.
2387 * Added AWAY message printing to the Irssi SILC client. Added
2388 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2390 * Added SCONNECT command to call the SILC's CONNECT command.
2391 Cannot use CONNECT directly since Irssi uses that internally.
2392 Affected file irssi/src/silc/core/silc-servers.c.
2394 Added ACTION local command. It is same as ME command but takes
2395 the channel as mandatory argument.
2397 Rewrote some of the Irssi's help files to suite for SILC
2400 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Added Makefile.defines[.in] that should for now on be included
2403 in all Makefile.am file in the source tree. That file includes
2404 all common compilation definitions for SILC source tree.
2406 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Minor changes to the ./prepare script to change the package
2409 name according the distribution name to the configure.in.
2411 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Created new distribution system. Added file `distributions'
2414 that defines all the distributions that can be created out of
2415 the SILC source tree. The ./prepare script now reads that
2416 file to determine how to prepare the distributions. The
2417 first argument to the ./prepare is the name of the distribution
2418 and second is the version of the distribution. If given
2419 without arguments it creates the default (toolkit) distribution
2420 with the default version (defined in ./prepare).
2422 All Makefile.am files that are subject to the distributions
2423 are now named as Makefile.am.pre. These are ./Makefile.am
2424 and lib/Makefile.am. Others may be changed later.
2426 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Added invite list, ban list, some key management and connection
2429 error message printing to module formats in the Irssi SILC client.
2431 * Added new silc_client_set_away_message to set the away message
2432 that is back to the person who sent private message. The
2433 affected file lib/silcclient/silcapi.h and the
2434 lib/silcclient/client_prvmsg.c.
2436 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Fixed the private message sending in the Irssi SILC client,
2439 added local command KEY to the Irssi SILC client.
2441 Added key management and key agreement message formats to the
2442 irssi/src/fe-common/silc/module-formats.[ch].
2444 Added USERS (alias WHO) printing, server/router operator
2445 indication and LIST command printing to the module formats.
2447 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Fixed channel joining notify handling, cumode notify handling
2450 from Irssi SILC client.
2452 * Added SILC specific module-formats to the Irssi SILC client so
2453 that SILC specific message hilighting, colors etc is possible.
2454 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2456 Added channel mode, channel user mode, actions, notices,
2457 whois and whowas printing to the the module-formats.c.
2459 * Fixed a bug in channel deletion in the server. The channel
2460 is not left to the cache even if the channel founder auth mode
2461 is set when there are no users anymore on the channel. Affected
2462 file silcd/server.c.
2464 * The silc_net_localhost now resolves the entire hostname including
2465 the domain name. Affected file lib/silcutil/silcnet.c.
2467 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Changed the ask_passphrase client operation to be ascynchronous.
2470 It has now a completion callback and a context that the
2471 application must call after it has got the passphrase from
2472 the user. Affected files lib/silcclient/silcapi.h,
2473 lib/silcclient/protocol.c, lib/silcclient/command.c and
2476 Added SilcAskPassphrase callback that the application calls
2477 to deliver the passphrase to the library.
2479 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2480 The public key verification and especially a certificate
2481 verification is asynchronous procedure.
2483 Added new SILC_SKE_STATUS_PENDING status to indicate the
2484 request is pending and a callback will be called to finalize
2487 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2488 indicate that remote end did not send its public key (or
2489 certificate), even though we require it. Added check for this
2490 condition in the SKE. This was a security bug, now fixed.
2492 Defined new SilcSKEVerifyCbCompletion callback that is called
2493 when the verification process is completed.
2495 The affected files lib/silcske/silcske_status.h and
2496 lib/silcske/silcske.[ch].
2498 * Changed the verify_public_key client operation to be async
2499 as well. Defined SilcVerifyPublicKey callback that is used to
2500 indicate the success of the public key verification process.
2502 Changed the server and client to use the new async client
2505 * Changed the Irssi SILC client's internal scheduler to be called
2506 twice as many times as it used to be. As a result the client
2507 should be a bit faster now. Affected file is
2508 irssi/src/silc/core/silc-core.c.
2510 * Added support to Irssi SILC client of asynchronous public key
2511 verification and passphrase inquiry. Affected file is
2512 irssi/src/silc/core/silc-core.c.
2514 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Do not say "You have left channel %s" in client library.
2517 Moved it to the application. Affected files are
2518 lib/silcclient/command.c and silc/client_ops.c.
2520 * Fixed silc_client_get_clients. Command context was not
2521 duplicated and was freed memory in the callback. Affected
2522 file lib/silcclient/idlist.c.
2524 * Do not say "you are now talking..." on JOIN command in the
2525 client library. The appliation must handle it.
2527 * Do not say ".. changed topic to" in command reply in the
2528 client libary. The application must handle it.
2530 * Fixed TOPIC command sending in the client library.
2532 * Fixed a memory leak in silc_client_command_free in the file
2533 lib/silcclient/command.c.
2535 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2537 * Imported a modified version of Irssi client to the source tree.
2538 The Irssi will be used to create a new client called
2539 Irssi SILC. Imported to irssi/.
2541 Added silc_core_init_finish function to the Irssi. Affected
2542 file irssi/configure.in.
2544 A lot changes in the Makefile.ams around the irssi tree.
2546 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Do not rehash if the new size is same as the old size of the
2549 hash table, in the silc_hash_table_rehash*. The affected file
2550 lib/silcutil/silchashtable.c.
2552 * Replaced hash_table_del_by_context calls from the server
2553 (when channel->user_list and client->channels) to the
2554 hash_table_del as it is sufficient and faster.
2556 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Added silc_hash_table_list, silc_hash_table_get and the
2559 SilcHashTableList structure to provide an alternative way to
2560 traverse the hash table. The affected files are
2561 lib/silcutil/silchashtable.[ch].
2563 * Changed the server's idlist routines to use the hash table
2564 routines to optimize the code.
2566 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Replaced the client entry's `channel' list and channel entry's
2569 `user_list' list to hash tables for optimized lookup. Changed
2570 the code to use the hash table interface around the code.
2571 Affected file lib/silcd/idlist.[ch].
2573 * Added `auto_rehash' boolean argument to the function
2574 silc_hash_table_alloc to indicate whether the hash table should
2575 auto-rehash when it thinks is appropriate time. It will
2576 increase the hash table size if the there is twice as much
2577 entries in the table than the size of the table, and will
2578 decrease the size if there are twice as less entries than
2579 the size of the table.
2581 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2585 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * silc_idcache_purge_by_context deletes the entry now by context
2588 as it is supposed to do. Affected file lib/silccore/idcache.c.
2590 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2591 client is not anymore valid (WHOWAS givens the info) and not
2592 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2594 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Removed the `data' and `data_len' arguments from the ID Cache
2597 interfaces and added `name' argument. ID Cache does not handle
2598 anymore the binary data only a names associated with given ID.
2600 * When hashing a Client ID with silc_hash_id the entire ID is
2601 not hashed anymore, instead only the hash of the Client ID is
2602 hashed. This way we can access the Client ID from the cache
2603 with Client ID but with the hash of the ID (which is a hash of
2604 the nickname) as well without any difference in performance.
2606 Added also silc_idcache_find_by_id_one_ext to do one on one
2607 searching when we have the actual ID. Added also function
2608 silc_hash_client_id_compare. The affected files are
2609 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2611 * When hashing the name associated with a ID it is always done
2612 in lowercase. This way we can access the cache without worrying
2613 about case-sensitivity, even though, for example nicknames are
2616 * Fixed a bug in server with channel message sending. It put
2617 wrong ID type as destination ID. The affected file
2618 silcd/packet_send.c.
2620 * silc_idcache_del_by_context now deletes from all hash tables
2621 by context. Affected file lib/silccore/idcache.c.
2623 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Changed the client library to use the new ID Cache interface.
2626 Changes around the source tree.
2628 * Added silc_hash_table_rehash_ext to rehash with specific
2629 hash function. Affected file lib/silcutil/silchashtable.[ch].
2631 * Added silc_hash_string_compare to compare two strings in the
2632 hash table. Affected file lib/silcutil/silcutil.[ch].
2634 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Added new function silc_idcache_del_by_context into the
2637 lib/silccore/idcache.[ch].
2639 * Changed the server's ID list routines to use the new ID Cache
2640 interface. Changes around the source tree.
2642 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added silc_hash_table_del[_by_context]_ext functions in to the
2645 lib/silcutil/silchashtable.[ch].
2647 Removed silc_hash_table_find_all* routines and added new
2648 silc_hash_table_find_foreach to replace them.
2650 Added silc_hash_table_replace_ext function as extended
2651 replacing function. Separated the simple hash table interface
2652 from the extended hash table interface in the file
2653 lib/silcutil/silchashtable.h.
2655 * Fixed minor bugs and changed it to use some of the new
2656 hash table functions in lib/silccore/idcache.c
2658 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Added new function silc_hash_table_find_all to return all keys
2661 in the hash table by the specified key. As the hash table is
2662 collision resistant it also makes it possible to have several
2663 duplicate keys in the hash table. This function may be used to
2664 find all of the keys from the hash.
2666 Added user_context arguments to the SilcHashFunction,
2667 SilcHashCompare and SilcHashDestructor to deliver user specified
2670 Added new fuctions silc_hash_table_find[_all]_ext to do
2671 extended lookup with specified hash and compare functions and
2672 specified user contexts.
2674 Added new function silc_hash_table_add_ext to add the key
2675 with specified hash function and user context.
2677 Added new function silc_hash_table_foreach to traverse all
2678 entrys in the hash table. Added SilcHashForeach callback
2681 Added new function silc_hash_table_del_by_context to delete
2682 the entry only if the context associated with the key matches.
2684 Affected files are lib/silcutil/silchashtable.[ch].
2686 * Removed silc_hash_[server/client/channel]_id and added just
2687 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2688 silc_hash_id_compare to compare two ID's using as the hash table
2689 comparison function. Added also silc_hash_data to hash
2690 binary data and silc_hash_data_compare to compare it.
2692 * Removed silc_idlist_find_client_by_hash as it is not needed
2693 anymore. Affected file silcd/idlist.[ch].
2695 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2696 to use internally the SilcHashTable. The new ID Cache is a lot
2697 faster than the old one. Some of the ID Cache interface was also
2698 rewritten and obsolete and stupid functions were removed.
2700 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added entry_count field to the SilcHashTable to keep the number
2703 of the entries in the table. Implemented the function
2704 silc_hash_table_rehash. Added new function
2705 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2707 Fixed a minor bug in silc_hash_table_free.
2709 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2710 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2711 into the lib/silcutil/silcutil.[ch].
2713 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Implemented a collision resistant hash table into the
2716 lib/silcutil/silchashtable[ch]. See the header and the source
2717 for the SilcHashTable API.
2719 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Merged dotconf version 1.0.2 into lib/dotconf.
2723 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Do not compile anything in lib/silcsim/* if the SIM support
2726 is not enabled. The tree should now compile without problems
2729 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Compiled the SILC under cygwin. Compiled and tested briefly
2732 without problems. More tests needed. The SIMs didn't compile
2735 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2737 * Fixed possible crash in silc_get_username in the
2738 lib/silcutil/silcutil.c.
2740 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Fixed a va_arg in silc/client_ops.c.
2744 * Oops, RC5 routines were named AES and caused some problems
2745 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2747 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Added new SilcIDIP structure into the lib/silccore/id.h and
2750 replaced the old `ip' fields from all SILC ID's to that type.
2751 This is a step towards IPv6 support.
2753 The silc_id_get_len takes now the ID as an extra argument.
2754 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2755 both IPv4 and IPv6 based ID's.
2757 The affected files are lib/silccore/id.[ch] and other files
2758 around the tree using these routines.
2760 * Removed the ID length arguments in server from various
2761 silc_server_send_notify_* routines -> they are not needed
2764 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Fixed memory leak in silc_encode_pem_file in the file
2767 lib/silcutil/silcutil.c.
2769 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Check minor version as well in the SKE. Affected files are
2772 silcd/protocol.c and lib/silcclient/protocol.c.
2774 * Added --identifier option to the server so that an identifier
2775 can be when creating the public key for the server. Affected
2776 file is silcd/silcd.c.
2778 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2779 lib/silccrypt/silcpkcs.c.
2781 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Register default ciphers and stuff when using -C option with
2784 the server. Affected file sildc/silcd.c.
2786 * Put back the servers public key filename format, it is better
2787 than the new one. For now, the client keys are saved with the
2788 new filename format. The affected file silc/client_ops.c.
2790 * Implemented the Cipher API for the rest of the ciphers that
2791 did not implement it or implemented it the wrong way.
2793 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Register default ciphers and stuff when using the -S option
2796 in the client. Affected file silc/silc.c. Same also when
2797 creating new key pair with -C option.
2799 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Fixed the silc_verify_public_key client operation function to
2802 save the public keys differently. The fingerprint is now
2803 used as filename and not the hostname. This way also the
2804 client keys are saved uniquely and not with hostnames. The
2805 affected file is silc/client_ops.c.
2807 * Trimmed the silc_hash_fingerprint function to remove extra
2808 whitespaces from the end of the fingerprint. The affected
2809 file is lib/silccrypt/silchash.c.
2813 * Added silc_cipher_register_default function to register all
2814 default ciphers. It can be used when configuration files
2815 does not exist and the application does not want any specific
2816 ciphers in any specific order.
2818 The SilcDList is now used as silc_cipher_list dynamically
2819 allocated cipher list. Removed the static list all together
2820 and now all ciphers must be allocated to the dynamic list.
2821 The silc_cipher_alloc routine was changed to check only the
2824 All silc_cipher_* routines that used to return int returns
2827 The affected files lib/silccrypt/silccrypt.[ch].
2829 * The same thing was done to silc_hash_* as for silc_cipher_*
2830 routines. Affected files lib/silccrypt/silchash.[ch].
2832 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2833 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2834 Added also silc_pkcs_[un]register[_default] functions.
2835 Removed the data_context from the PKCS API.
2837 * Added silc_hmac_register_default function to register default
2838 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2839 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2840 to unregister all hmacs at once.
2842 * Register the default ciphers, hash functions, PKCSs and HMACs
2843 if client's configuration file does not exist. The affected
2846 * The client did not load the hash functions from the SIM
2847 modules at all. Added support for this. Affected file is
2848 silc/clientconfig.c.
2850 * When decoding public key with silc_pkcs_public_key_decode, check
2851 the supported algorithm only if PKCS are registered. Affected
2852 file lib/silccrypt/silcpkcs.c. The same was done with the
2853 silc_pkcs_private_key_decode.
2855 * Fixed the SILC List routines to keep the list always in order.
2856 It used to change the list's order when traversing the list but
2857 not it preserves the order. Affected file lib/trq/silclist.h.
2859 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Added the client library to use the SilcSocketConnection's
2862 reference counter (by silc_socket_dup) to prevent the bug that
2863 the socket object may be freed underneath async operation.
2865 * The name resolv library checking fixes in the configure.in.pre.
2868 * Created new version of the protocol drafts for future
2869 development. The -03 drafts are the ones that will be changed
2870 in the trunk now and the -02 will remain as they are.
2872 * Send list of CUMODE notifys to the router when announcing
2873 the channel users to the router. Affected file silcd/server.c.
2874 If the router receiving channel founder CUMODE for a channel
2875 that already has channel founder it will send CUMODE notify
2876 to the sender to remove the channel founder rights from the
2877 announced client. Affected file silcd/packet_receive.c.
2879 * The CUMODE notify may now use Server ID as well as the entity
2880 who changes the mode. Updated protocool specs.
2882 * Updated INSTALL and README files.
2884 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * New web pages in the http://silc.pspt.fi. The pages was
2891 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Implemented the [DenyConnectin] config section in the server.
2894 Added silc_server_config_denied_conn to check whether incoming
2895 connection is denied. Affected file silcd/serverconfig.[ch].
2897 * Do not check the ports when checking the incoming configuration
2898 data if the port is 0, meaning any. Affected file is
2899 silcd/serverconfig.c.
2901 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Fixed buffer overflow in silc_string_compare in the file
2904 lib/silcutil/silcutil.c.
2906 * Fixed double free in silc_server_command_leave in the file
2909 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Fixed the version checking in the server. Affected file is
2914 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Fixed the configuration data fetching when accepting new
2917 connections in the server. Affected file silcd/server.c.
2919 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added `sender_entry' argument to the function
2922 silc_server_packet_relay_to_channel so that we can check
2923 whether some destination actually belongs to the same route
2924 the sender belongs (ie, we must not resend the packet to the
2925 sender). Affected file silcd/packet_send.[ch].
2927 * Added `servername' field to the SilcClientEntry in the server
2928 to hold the name of the server where client is from. Affected
2929 file is silcd/idlist.h.
2931 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Moved the channel message encrypting in the router betwen
2934 router connections from silc_server_channel_message to the
2935 silc_server_packet_relay_to_channel since we want to check
2936 whether we have anybody channel before encrypting anything.
2937 Affected files silcd/packet_[receive/send].c.
2939 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Fixed the [AdminConnection] server config section to support
2942 multiple entries. Affected file silcd/serverconfig.c.
2944 * Added support into the server to check the validity of the
2945 incoming connection before executing any KE or authentication
2948 * The connection configuration is now saved to the KE and
2949 connection auth protocol contexts and not fetched anymore in
2950 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2952 * The local hosts listenning address and port is also resolved
2953 now when starting the server. We want to have the socket object
2954 to include the real address and port for the listener. Added
2955 new function silc_net_check_local_by_sock into the files
2956 lib/silcutil/silcnet.[ch].
2958 * Fixed a broadcast bug in server -> do not broadcast if we
2961 * Fixed a routing bug. Do not route broadcast packets ever.
2962 Broadcast packets must be processed always and not routed since
2963 they may be destined to some other host than yourself and thus
2964 would get routed without no good reason. Affected file is
2967 * Added function silc_server_config_is_primary_route to check
2968 whether primary router connection has been configured (a router
2969 configuration that we are initiating). If there is not, we
2970 will assume that there is only two routers in the SILC network
2971 and we will use the incoming router connection as our primary
2972 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2974 * Changed the order of the broadcasting. Broadcast _after_ the
2975 packet has been processed not before. Affected file is
2978 * Fixed a [ClientConnection] parsing bug. The port was never
2979 parsed correctly thus resulting to port 0. Affected file
2980 silcd/serverconfig.c.
2982 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2983 argument and did not set the broadcast packet flag. Affected
2984 file silcd/packet_send.c. Fixed same bug in the function
2985 silc_server_send_notify as well.
2987 * If we receive NEW_ID packet for our own ID in the server, ignore
2990 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Removed the nickname from the Private Message Payload.
2995 Updated the code and the protocol specs.
2997 * Updated protocol specs for submitting to the IETF.
2999 * Tweaked the Random Number Generator a bit. Affected file
3000 lib/silccrypt/silcrng.c. Exported a new function
3001 silc_rng_[global]_add_noise which can be used to add more
3004 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Do not parse packets with different timeout when protocol
3007 is active -> may cause problem with rekey. Affected file
3010 * When server receives signoff notify it must not create
3011 new channel key if the client is on any channels since the
3012 sender of the signoff notify will create it.
3014 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Added printing of error messages during SKE protocol from the
3017 failure packet sent by server during SKE. Affected file
3020 * Removed the client's failure_callback handling with timeout
3021 and handle it immediately when received.
3023 * The SKE library returned wrong type in SUCCESS and FAILURE
3024 packets. They must be 32 bit MSB not 16 bit MSB.
3026 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Ok, rewrote the logic of the re-key and now it seems to work.
3029 I tested it on high traffic with frequent re-keys without
3030 problems. Added hmac_receive (and renamed hmac to hmac_send)
3031 in SilcClientConnection in lib/silcclient/client.h and
3032 in SilcIDListData in silcd/idlist.h. Also, removed the
3033 SilcPacketParserContext's cipher and hmac fields as they are
3034 not needed anymore and actually caused some problems when
3035 the ciphers and hmac's changed underneath the packet parser.
3037 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * If re-key protocol is active then process the incoming packets
3040 synchronously since we must assure that icoming packets encrypted
3041 with the old key is processed before the new keys is set to
3042 use. This is true other packets than for REKEY packets.
3043 Affected file silcd/server.c. The same was done to client library
3044 as well, affected file lib/silcclient/client.c.
3046 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Fixed bug in client and server to accept the force send if
3049 the packet is send from silc_[server/client]_packet_process
3050 function. Otherwise the packets are never delivered, oops.
3052 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Disable force sending of packets when REKEY protocol is active.
3055 We must assure that no packet is sent directly when rekey is
3056 performed. All packets must be sent through packet queue.
3057 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3058 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3059 function is silc_[server/client]_packet_send_real to check
3062 * Replaced the SIM paths from example config files to
3063 /usr/local/modules. Also, make install creates now
3064 /usr/local/silc/logs directory to hold all the SILC server
3067 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Made the configure.in.pre work on Solaris. Patch by salo.
3071 * Made all ciphers compatible with non-x86 machines. Defined
3072 CBC mode macros into lib/silccrypt/ciphers_def.h.
3074 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Fixed the make install.
3078 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * When MAC computation fails the silc_packet_decrypt returned 0
3081 even though it was supposed to return -1. Fixed this. The
3082 affected file is lib/silccore/silcpacket.c.
3084 * Do not replace the config files in /etc/silc (in make install)
3085 if they already exist. Affected file ./Makefile.am.
3087 * Do not send re-key packets immediately but through packet queue.
3088 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3090 * Changed silc_net_check_host_by_sock to return FALSE if the
3091 IP/DNS could not be resolved. Though, it returns the IP address
3092 now even if it could not resolve it (but returns also FALSE).
3093 Affected file lib/silcutil/silcnet.[ch].
3095 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Added silc_pkcs_decode_identifier to decode the public key's
3098 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3099 Added also silc_pkcs_free_identifier. Added also new context
3100 SilcPublicKeyIdentifier.
3102 * Added -S option to the silc client. It is used to dump the
3103 contents of the specified public key file.
3105 * Changed the PKCS api to return the public key length when
3106 setting the public key.
3108 * Fixed a fatal bug in the public and private key file loading.
3109 Affected file lib/silccrypt/silcpkcs.c.
3111 * Execute the packet parsing for client with zero (0) timeout
3112 if the protocol is active. Affected file silcd/server.c.
3114 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Made the key generation options to the silcd program. Added
3117 -C option, equivalent to client's option.
3119 * Added new [ServerKeys] config section to the server. It
3120 configures the server's public and private key.
3122 * Defined generic Public Key Payload into the protocol
3123 specification to send specific type of public keys and
3126 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3127 public key or certificate.
3129 * Implemented the GETKEY command to the server and to the
3130 client library and on user interface.
3132 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Made preliminary `make install' work.

3151 state of the protocol. Affected file is
3152 lib/silccore/silcprotocol.[ch].
3154 * Added the re-key support with and without PFS to the client
3155 library. Re-key is performed once in an hour, by default.
3157 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3158 Added silc_client_rekey_callback and silc_client_rekey_final.
3159 Affected files are lib/silcclient/protocol.[ch] and

3163 SilcClientConnection structure; not needed. Affected file is
3164 lib/silcclient/client.h.
3168 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Do not ask whether user wants to use the negotiated private key
3171 for private messages, just use it. Affected file is
3172 silc/local_command.c.
3174 * Added `send_enc_key' and `enc_key_len' fields to the
3175 SilcIDListData structure since they are needed in the re-key
3176 phase. Affected file is silcd/idlist.[ch].

3199 * Changed _ALL_ unsigned long and unsigned int to uint32,
3200 unsgined short to uint16 in the source tree.
3202 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3203 not handle clients that has entry->data.registered == FALSE.
3204 They are not in the network anymore. Affected file is
3207 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3210 server. Affected file is silcd/server.c.
3212 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3213 Added also silc_notify_payload_encode_args into the
3214 lib/silccore/silcnotify.[ch].
3216 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3217 Affected file silcd/packet_receive.c.
3219 * Implemented the SERVER_SIGNOFF notify handling in the client
3220 library. Affected file lib/silcclient/client_notify.c. Also,
3221 implemnted the printing of the SERVER_SIGNOFF info to the
3222 application. Affected file silc/client_ops.c.
3224 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3225 if the deleting was successful. Affected file silcd/idlist.[ch].
3227 * Added support for public key authentication in the connection
3228 authentication protocol in the client library. Affected file
3229 lib/silcclient/protocol.c.
3231 * Changed the server's silc_idlist_get_clients_by_* interface
3232 to support already allocated array so that new entries may be
3233 added to pre-allocated array. Affected file silcd/idlist.[ch].
3234 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3235 and command replies.
3237 * All command reply functions in the server now calls the
3238 pending command callback even if error occured. This way the
3239 error will be delivered to the client as well. Affected files
3240 silcd/command.c and silcd/command_reply.c.
3242 * Fixed INFO command to return local server's info if no server
3243 was provided. Affected file lib/silcclient/command.c.
3245 * Removed RESTART command for good. Updated the code and the
3248 * Rewrote parts of the task system. It is a bit simpler now.
3249 Removed unsued task priorities. The affected files are
3250 lib/silcutil/silctask.[ch].
3252 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Moved the USERS printing from the library to the application.
3255 Affected files lib/silcclient/command.c and silc/client_ops.c.
3257 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Added channel key re-key support. The re-key is perfomed
3262 only by the router and is done once in an hour. Added `rekey'
3263 field to the SilcChannelEntry in the server. Affected files
3264 silcd/server.c and silcd/idlist.h.
3266 * Added silc_task_unregister_by_context into the file
3267 lib/silcutil/silctask.[ch].
3269 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Added SILC_UMODE_GONE mode to indicate when the client is not
3272 present in the SILC network. Added also support to the local
3273 command AWAY that will set this mode. Added support of showing
3274 "xxx is gone" in WHOIS command. The USERS command shows the
3275 gone status as well.
3277 * Fixed setting server and router operator privileges in the
3278 server's UMODE command. Affected file silcd/command.c.
3280 * Merged the SKE KE1 and KE2 payloads into one payload. The
3281 new KE payload is equivalent to the old KE2 payload.
3283 Cleaned up the SKE Start Payload parsing. It now uses the
3284 simple buffer unformatting to do the parsing. A lot faster
3287 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3288 to the SKE that is used to indicate whether both of the SKE
3289 parties should perform authentication. By default only the
3290 responder performs authentication. By setting this flag also
3291 the initiator must do authentication. By default it is unset
3292 since in normal SKE case, client to server connection, only
3293 the responder should do authentication. When doing SKE between
3294 two clients both should perform authentication. Updated the
3295 code and the protocol specs.
3297 * A little fix to IDENTIFY command in the server. Search the
3298 client first by hash not nickname. Affected file is
3301 * Fixed the silc_client_close_connection to support closing
3302 the client to client connections wihtout deleting too much
3303 data. Affected file lib/silcclient/client.c.
3305 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3306 are received if protocol used to be active but is not anymore
3307 the application would crash due to NULL pointer dereference.
3308 Affected files silcd/server.c and lib/silcclient/client.c.
3310 * Added `hash' field to the SilcClientConnection to include
3311 the hash function negotiated in the SKE protocol.
3313 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3314 to set the channel founder authentication data. A client can
3315 claim the founder rights later by providing the authentication
3316 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3317 This way the channel founder can regain the channel founder
3318 privileges even it is left the channel. This works only on
3319 local server and the client must be connected to the same
3320 server to be able to regain the founder rights. Updated the
3321 protocol specs accordingly.
3323 Added support to the CMODE command in the client to set the
3324 founder auth data. Read the README to see how to set it.
3326 Added support to the CUMODE command to claim the founder
3327 rights. Read the README to see how to do it.
3329 Added support for the founder authentication to the Channel
3330 Entry in the server. Affected file silcd/idlist.h.
3332 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3333 server's CMODE command. Affected file silcd/command.c.
3335 * Added the following new functions into lib/silccore/silcauth.[ch]:
3336 silc_auth_get_method and silc_auth_get_data.
3338 * The server now saves the remote hosts public key to the
3339 SilcIDListData pointer. Affected file silcd/protocol.c.
3341 * The normal server now does not remove the channel entry from
3342 the cache if the founder authentication data is set. It used
3343 to remove it if the founder was the last one on the channel on
3344 the server and left the channel. The auth data is saved and
3345 if the channel is re-joined later the old entry is used with
3346 the old auth data. Affected files silcd/command_reply.c and
3349 * Removed the `pkcs' field from the SilcIDListData structure
3350 in the server; it is not used. Affected file silcd/idlist.h.
3352 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Fixed packet processing on slow links. Partial packets were
3355 never re-processed because the incoming data buffer was cleared
3356 by the application. Application must not directly clear the
3357 sock->inbuf, the packet processing routines handle it. Fixed
3358 this in client library and in server.
3360 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Fixed the WHOIS and IDENTIFY send reply function to really
3363 check whether to send list or just one entry. Affected file
3366 * Cleaned up the LEAVE command's channel key distribution. The
3367 affected file silcd/command.c.
3369 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3370 can enforce the channel mode as well. In that case the ID
3371 includes the ID of the server. The code now enforces the
3372 mode change if the router have different mode than the server.
3374 * The notify client operation with CMODE_CHANGE notify can now
3375 return NULL client_entry pointer if the CMODE was not changed
3376 by client. Application must check for this.
3378 * Added <Server ID> argument to INFO command to support server
3379 info fetching by Server ID.
3381 * Added silc_server_announce_get_channel_users to get assembled
3382 packets of channel users of the specified channel. Affected
3383 file silcd/server.[ch].
3385 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3386 was freed underneath the ID Cache.
3388 * Re-announce clients when the server received CHANNEL_CHANGE
3389 notify from the router. Affected file silcd/packet_send.c.
3391 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3394 crashed since it did not handle the fact that there is no cipher
3395 called "3" and didn't check the error condition. Now fixed.
3397 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3398 flag. It can be used to send message requests.
3400 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Implemented the RESTART command in the client.
3404 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3405 notice type messages. Added notice printing to the user
3408 * The channel keys are not re-generated if the channel's mode
3409 is PRIVKEY, ie private key on the channel exists. Affected
3410 files silcd/server.c and silcd/command.c.
3412 * Fixed a little bug in channel message delivery when channel
3413 private keys are set in the server. Affected file is
3414 silcd/packet_send.c.
3416 * Changed the setting on channel->on_channel = TRUE from the
3417 silc_client_save_channel_key to the JOIN command reply. The
3418 key payload is not received if the private channel key is set.
3419 Affected file lib/silcclient/command_reply.c and the
3420 lib/silcclient/client_channel.c.
3422 * When the CMODE_CHANGE notify is sent and the channel private
3423 key mode is removed the channel key must be re-generated in
3424 other cells as well. Added this support for the router in the
3425 silcd/packet_receive.c.
3427 * Added new local command NOTICE to send notice message on
3428 channel. Affected file silc/local_command.[ch].
3430 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Added new local command ME to the client. It is used to send
3433 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3434 some action. Affected file silc/local_command.[ch].
3436 * Changed channel_message and private_message client operations
3437 to deliver the message flags to the application. Added also
3438 the `flags' arguments to the silc_client_send_channel_message
3439 and silc_client_send_private_message functions. Affected file
3442 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Redefined the Private Message Payload to support private message
3445 keys and to support the new private message flags. Updated
3446 the protocol specs. Flags makes it possible to have for example
3447 CTCP style messages.
3449 * Added new type SilcPrivateMessagePayload and defined an API
3450 for it in the lib/silcclient/silcprivate.[ch].
3452 * Tested private message private keys successfully. Tested the
3453 private message key set, unset and list commands with the new
3456 * Redefined the Channel Message Payload to include the channel
3457 message flags (equal with private message flags) to support
3458 for example CTCP style messages.
3460 * Defined some of the message (for channel and private message)
3461 flags. Updated the protocol specs and added the flags to the
3462 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3464 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Added SilcKeyAgreementStatus type to the key agreement routines
3467 to indicate the current status and error if one occured.
3468 The status types are defined in the lib/silcclient/silcapi.h.
3470 * Added new local command KEY that is used to set and unset private
3471 keys for channels, set and unset private keys for private messages
3472 with remote clients and to send key agreement requests and
3473 negotiate the key agreement protocol with remote client. The
3474 key agreement is supported only to negotiate private message keys,
3475 it currently cannot be used to negotiate private keys for channels,
3476 as it is not convenient for that purpose.
3478 * Fixed a minor pending callback setting bug in the function
3479 silc_client_get_client_by_id_resolve, now the function works.
3480 Affected file lib/silcclient/idlist.c.
3482 * Added function silc_net_get_local_port to get local bound
3483 port by socket. Added to lib/silcutil/silcnet.[ch].
3485 * Added `sockets' and `sockets_count' fields to the SilcClient
3486 object. They hold the sockets of the listenning sockets in
3487 the client. Listenning sockets may be for example the key
3488 agreement server. Affected file lib/silcclient/client.[ch].
3489 Added functions the silc_client_add_socket and the
3490 silc_client_del_socket. They are exported to the application
3493 * Added ~./silc/clientkeys to support other client's public keys.
3495 * Renamed verify_server_key client operation to verify_public_key
3496 and added one argument to indicate the type of the connection
3497 (server, client etc.).
3499 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Added silc_server_connection_auth_request to handle the
3502 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3503 silcd/packet_receive.[ch].
3505 * Added silc_server_send_connection_auth_request into the
3506 silcd/packet_send.c to send the connection auth request packet.
3508 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3511 * Fixed the public key authentication in responder side in the
3512 server. The `auth_data' pointer includes the SilcPublicKey
3513 not the path to the public key. Affected file silcd/protocol.c.
3515 * Implemented the public key authentication in the initiator side
3516 in the server. Affected file silcd/protocol.c.
3518 * Removed the [RedirectClient] config section from the server
3519 configuration. Is not needed and I don't want to implement it.
3521 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * Cleaned up the CMODE command in the server. It now works
3524 correctly and supports all the modes defined in the protocol.
3525 Affected file is silcd/command.c.
3527 * Added `hmac_name' field to the SilcChannelEntry in the server
3528 to hold the default HMAC of the channel. It can be set when
3529 creating the channel (with JOIN command). Affected files
3532 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3533 type to indicate the change of the current cipher and hmac
3534 on the channel. Client can safely ignore the <cipher> argument
3535 (if it chooses to do so) since the CHANNEL_KEY packet will
3536 force the channel key change anyway. The <hmac> argument is
3537 important since the client is responsible of setting the new
3538 HMAC and the hmac key into use.
3540 * Fixed the CMODE command in the client library as well.
3542 * Tested CMODE command in router environment successfully.
3544 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Show the version of the remote client (or server) when connecting
3547 to the server. It is logged to the log file. Affected file
3548 is silcd/protocol.c.
3550 * Fixed the KILLED notify handling in the client library. The
3551 client must be removed from all channels when receiving the
3554 Also, do not remove the client entry when giving the KILL
3555 command but when the KILLED notify is received.
3557 * Removed silc_idlist_find_client_by_nickname from the server.
3558 Not needed anymore. Affected files silcd/idlist.[ch].
3560 * Implemented the CHANNEL_CHANGE notify type handling to the
3561 server. Affected file silcd/server.c.
3565 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Added silc_server_send_notify_invite to send the INVITE
3568 notify between routers.
3570 * Implemented the INVITE command correctly to the server.
3572 * Implemented the INVITE notify type handling in the server.
3574 * Implemented the INVITE command to the client library and on the
3577 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Added function silc_server_get_client_resolve to find the
3580 client entry by ID from all ID lists and then resolve it
3581 (using WHOIS) if it cannot be found. Affected file is
3584 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Implemented the BAN command to the client library.
3588 * The JOIN command in the server now checks the invite list
3591 * Changed the silc_command_reply_payload_encode_va and the
3592 silc_command_payload_encode_va to support that if argument is
3593 NULL it ignores and checks the next argument. Affected file
3594 lib/silccore/silccommand.c.
3596 * Added silc_server_send_notify_ban to send the BAN notify
3597 type between routers.
3599 * Chaned the silc_notify_payload_encode to support that if
3600 argument is NULL it ignores and checks the next argument.
3601 Affected file lib/silccore/silcnotify.c.
3603 * Tested ban lists in router environment successfully.
3605 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Implemented BAN command to the server, in silcd/command.[ch].
3609 * Removed the BAN and INVITE_LIST modes from the CMODE command
3612 * Added function silc_string_match to regex match two strings.
3613 Affected files lib/silcutil/silcutil.[ch].
3615 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Redefined parts of the SilcChannelEntry in the server to support
3618 the new ban and invite lists.
3620 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Redefined the INVITE command. The same command can be used to
3623 invite individuals to the channel but also to manage the invite
3624 list of the channel (to add to and remove from the invite list).
3625 Updated the protocol specs.
3627 * Added new command SILC_COMMAND_BAN that can be used to manage
3628 the ban list of the channel. Updated the protocol specs.
3630 * Removed the channel modes: the SILC_CMODE_BAN and the
3631 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3632 in the CMODE command. The equivalent features are now available
3633 using INVITE and BAN commands. Updated the protocol specs.
3635 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3636 in the network about change in the current ban list. The notify
3637 type is not used by the client.
3639 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3640 support the invite lists.
3642 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Added new function silc_string_regexify that converts string
3645 including wildcard characters into regex string that can
3646 be used by the GNU regex library. Added into the file
3647 lib/silcutil/silcutil.[ch].
3649 Added silc_string_regex_combine to combine to regex strings
3650 into one so that they can be used as one regex string by
3651 the GNU regex library. Added into the file
3652 lib/silcutil/silcutil.[ch].
3654 Added silc_string_regex_match to match two strings. It returns
3655 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3657 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Imported GNU regex to the soruce tree into lib/contrib.
3660 Fixed some compiler warning from the regex.c.
3662 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Fixed MOTD command in the server to work in router environment.
3666 * Fixed the MOTD command in the client library to support
3667 the server argument in the command.
3669 * Added `nickname_len' argument to the silc_idlist_add_client
3670 in the server, as the `nickname' argument may be binary data
3673 * Added silc_idlist_get_channels to return all channels from
3676 * Implemented LIST command to the server. Affected file is
3679 * Implemented the LIST command to the client library and on the
3682 * Added [<user count>] argument to the LIST command reply.
3683 With private channels the user count is not shown.
3685 * Updated TODO and README.
3687 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * The client entry's data.registered must be TRUE even with
3690 global client entry on global client list. The data.registered
3691 is used to check whether the client is anymore in the network,
3692 for example with WHOWAS command so it must be valid.
3694 * Fixed the WHOWAS command in the server. It now actually works
3695 in router environment. Added function into silcd/command_reply.c
3696 silc_server_command_reply_whowas_save.
3698 * Added silc_idlist_purge function to the silcd/idlist.c
3699 to periodically purge the ID Cache.
3701 * Fixed INFO command in the server. It works now in router
3702 environment. Added <server name> argument to the INFO command
3703 reply. Updated the protocol specs.
3705 * Fixed minor bug in silc_idcache_purge to not purge if the
3706 expire value is zero.
3708 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3709 they were buggy because of the WHOWAS information.
3711 * Fixed local command MSG to handle the async resolving of
3712 the remote client properly. It used to fail the first MSG.
3713 Affected file silc/local_command.c.
3715 * Added `data_len' field to SilcIDCache context.
3717 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Update TODO. Todo in commands in the server.
3721 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3724 used by routers as broadcast packet to inform other routers
3725 about the changed user mode.
3727 Implemented the notify handling in the server. Affected file is
3728 silcd/packet_receive.c. Added the function
3729 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3731 * Added new generic Channel Payload and deprecated the New Channel
3732 Payload. The New Channel Payload is now the generic Channel
3735 * Added new argument `mode' to the silc_server_send_new_channel
3736 as it is required in the Channel Payload now.
3738 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3739 and created a new and real SilChannelPayload to represent the
3740 new generic Channel Payload. Implemented the encode/decode
3741 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3743 * Added silc_server_get_client_channel_list to return the list
3744 of channels the client has joined for WHOIS command reply.
3745 Affected file silcd/server.[ch].
3747 * Implemented the channel list sending in the WHOIS command reply
3748 in server and in the client.
3750 Implemented the channel list displaying on the user interface
3751 as well. Affected file silc/client_ops.c.
3753 * Added silc_channel_payload_parse_list to parse list of Channel
3754 Payloads. It returns SilcDList list of SilcChannelPayloads.
3755 Client for example can use this function to parse the list of
3756 channels it receives in the WHOIS command reply. The caller
3757 must free the list by calling silc_channel_payload_list_free.
3758 Affected files lib/silccore/silcchannel.[ch].
3760 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Added one new argument <user mode> to the WHOIS command reply
3763 to return the mode of the user in SILC. Updated the protocol
3766 Implemented it to the server and client.
3768 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Fixed the mode printing on the user interface on joining.
3771 Affected file silc/client_ops.c.
3773 * Implemented the UMODE command and user modes in general to the
3774 client library and to the user interface.
3776 * Implemented the UMODE command to the server.
3778 * The server now sends UNKNOWN_COMMAND error status if client sends
3779 unknown command. Affected file silcd/command.c.
3781 * All server commands now handle the command identifier the right
3782 way when sending the command reply to the client. The client can
3783 use to identify the command replies with the identifier.
3785 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Added silc_server_get_client_route to resolve the route to
3788 the client indicated by the client ID. Affected file is
3791 * Added silc_server_relay_packet as general function to relay
3792 packet to arbitrary destination. This deprecates functions
3793 like _send_private_message_key, _relay_notify etc. Affected
3794 file is silcd/packet_send.[ch].
3796 Removed silc_server_send_key_agreement,
3797 silc_server_send_private_message_key and
3798 silc_server_packet_relay_notify functions from the file
3799 silcd/packet_send.[ch].
3803 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3804 server. Affected file silcd/packet_receive.[ch].
3806 * Implemented the KILL command to the client. Implemented the
3807 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3808 Affected files lib/silcclient/command[_reply].c and
3809 lib/silcclient/client_notify.c. Implemented the KILL notify
3810 printing in the user inteface.
3812 * Fixed a lot silc_parse_nick memory leaks from the client
3813 library in the file lib/silcclient/command.c.
3815 * Changed the silc_server_send_notify_on_channels's `sender'
3816 argument from SilcSocketConnection to SilcClientEntry to
3817 check the sender as entry and not as connection object and not
3818 to send to the client provided as argument. The affected file
3819 is silcd/packet_send.[ch].
3821 * The notify packets that are destined directly to the client used
3822 to not to be processed by the server. Now changed that and the
3823 server processes all notify packets. After relaying the packet
3824 to the client the notify packet is processed in the server.
3826 * The silc_server_free_client_data now checks whether there is
3827 pending outgoing traffic for the client and purges the data to
3828 the network before removing the client entry.
3830 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3833 an client is killed from the SILC Network. Updated the protocol
3836 Added new function silc_server_send_notify_killed to the
3837 silcd/packet_send.[ch].
3839 * Added function silc_server_packet_relay_notify to relay notify
3840 packets that are destined directly to a client. In this case
3841 the server does not process the notify packets but merely relays
3842 it to the client. Affected file silcd/packet_send.[ch].
3844 Added also silc_server_packet_process_relay_notify to check
3845 whereto relay the notify. Affected file is
3846 silcd/packet_receive.[ch].
3848 * Implemented the KILL command to the server.
3852 * Added the backup schema desgined last fall to the protocol
3853 specs for everyone to see. The specification is in the
3854 *-spec-xx.txt draft and the packet type definitions for the
3855 backup routers is in *-pp-xx.txt draft. Thusly, added also
3856 new packet type SILC_PACKET_CELL_ROUTERS.
3858 * A big security problem in the implementation discovered. The
3859 signoff of an client did not cause new channel key generation
3860 which it of course should've done. The channel keys must be
3861 always re-generated when client leaves (or signoffs) the channel.
3862 The silc_server_remove_from_channels funtion now handles
3863 the channel key re-generation.
3865 * Added `sender' argument to the silc_server_send_notify_on_channels
3866 to not to send the client provided as argument. Affected file
3867 silcd/packet_send.[ch].
3869 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Implemented OPER and SILCOPER commands into the server and
3874 * Added silc_auth_verify and silc_auth_verify_data to verify
3875 the authentication directly from the authentication payload.
3876 It supports verifying both passphrase and public key based
3877 authentication. Affected file lib/silccore/silcauth.[ch].
3879 * Added `hash' field to the SilcIDListData structure. It is the
3880 hash negotiated in the SKE protocol. Affected file is
3883 * Slight redesigning of the SilcAuthPayload handling routines.
3884 Do not send SilcPKCS but SilcPublicKey as argument.
3886 * Implemented the public key authentication support to the
3887 serverconfig. The public key is loaded from the provided path
3888 and saved as authentication data to void * pointer. Thus,
3889 changed the unsigned char *auth_data to void *auth_data;
3891 * Fixed SHUTDOWN command to send the reply before the server
3892 is shutdown. :) Affected file silcd/command.c.
3894 * Fixed fatal bug in CONNECT command. The hostname was invalid
3895 memory and server crashed. Affected file silcd/command.c.
3897 * Fixed fatal bug in CLOSE command. The server_entry became
3898 invalid but was referenced later in the command. Affected file
3901 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Fixed fatal bug in failure packet handling. Server ignored
3904 the failure and thus crashed when it came.
3908 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3911 that the command may be executed only once in (about) 2 seconds.
3912 The old SILC_CF_LAG flag is same but allows command bursts up
3913 to five before limiting.
3915 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3916 server code. Various commands now includes the CF_LAG_STRICT
3917 flag to disallow any kind of miss-use of the command.
3919 * Fixed the silc_buffer_unformat to not to allocate any data
3920 if the length of the data is zero. It used to allocate the
3921 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3923 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Changed the format of AdminConnection configuration section
3926 in the server. Added username of the admin to the format.
3927 Affected files silcd/serverconfig.[ch].
3929 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3930 to return admin configuration data by host, username and/or
3933 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Implemented WHOWAS command to the server. Added the functions:
3937 silc_server_command_whowas_parse,
3938 silc_server_command_whowas_send_reply,
3939 silc_server_command_whowas_from_client and
3940 silc_server_command_whowas_from_server
3942 * Added <Client ID> argument to the WHOWAS command reply. Updated
3943 the protocol specs accordingly.
3945 * Implemented WHOWAS command and command_reply to the client
3948 Implemented the WHOWAS printing on the user interface.
3950 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Added new argument to the WHOWAS command reply, the real name.
3953 It is an optional argument. Updated the protocol specs.
3955 * Added SilcIDCacheDestructor callback that is registered when
3956 the SilcIDCache is allocated. The callback is called when
3957 an cache entry in the ID Cache expires, or is purged from the
3958 cache. Added into lib/silccore/idcache.[ch].
3960 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3961 to destruct the client entries when the cache entry expires.
3962 Other ID Cache's in server and in the client library ignores
3965 * If the ID Cache entry's `expire' field is zero then the entry
3966 never expires. Added boolean `expire' argument to the
3967 silc_idcache_add function in the lib/silccore/idcache.[ch].
3968 If it is TRUE the default expiry value is used.
3970 * Added silc_server_free_client_data_timeout that is registered
3971 when client disconnects. By default for 5 minutes we preserve
3972 the client entry for history - for WHOWAS command.
3974 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added support to the server to enforce that commands are not
3977 executed more than once in 2 seconds. If server receives
3978 commands from client more frequently, timeout is registered
3979 to process the commands. Affected file silcd/command.c.
3980 Added new function silc_server_command_process_timeout.
3982 * Changed NICK_NOTIFY handling in client library to check that
3983 if the client's nickname was changed, so there is no need to
3984 resolve anything from the server.
3986 * Removed error printing from the WHOIS and IDENTIFY commands.
3987 If error occurs then it is ignored silently in the client library.
3988 The application, however, may map the received error to
3989 human readable error string. The application currently maps
3990 the NO_SUCH_NICKNAME error to string.
3992 * Made the command status message public to the application. Moved
3993 them from lib/silcclient/command_reply.c to
3994 lib/silcclient/command_reply.h. The application can map the
3995 received command status to the string with the
3996 silc_client_command_status_message function.
3998 * Added check to the server to check that client's ID is same
3999 as the Source ID in the packet the client sent. They must
4002 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Added dist-bzip hook to the Makefile.am to make bzip2
4005 compressed distributions.
4007 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Server now enforces the maximum length for the nickname and
4010 the channel as protocol specification dictates. 128 bytes for
4011 nickname and 256 bytes for channel name.
4013 * Moved the WHOIS printing to the application. The client libary
4014 does not print out the WHOIS information anymore, the application
4015 must do it. Renamed silc_client_command_reply_whois_print to
4016 the silc_client_command_reply_whois_save.
4018 The client's idle time is also sent to the application now, and
4019 the idle is shown on screen.
4021 * Added silc_client_command_reply_identify_save to save the
4022 received IDENTIFY entries.
4024 * Do not check for channel private keys in message sending and
4025 reception if the channel does not have the PRIVKEY mode set.
4026 Affected file lib/silclient/client_channel.c.
4028 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4031 just surfaced after chaning the JOIN procedure.
4033 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added silc_client_get_clients_by_list to get client entries
4036 from Client ID list, that is returned for example by JOIN
4037 and USERS command replies. The application should use this
4038 function for example when JOIN command reply is received to
4039 resolve the clients already on the channel (library does not
4040 do that anymore as USERS command reply is not used in the JOIN
4041 procedure anymore). Affected files lib/silcclient/silcapi.h and
4042 lib/silcclient/idlist.c.
4044 * JOIN command reply and USERS command reply returns now SilcBuffer
4045 pointers instead of unsigned char pointers when returning
4046 the client list and mode list.
4048 * Added <Client ID> argument to the JOIN command reply, mainly
4049 for the server to identify for which client the command was
4050 originally sent. Updated protocol specs accordingly.
4052 * Added SilcDlist private_key pointer to the SilcChannelEntry
4053 in the client to support the channel private keys. Affected
4054 file is lib/silcclient/idlist.h.
4056 * Added SilcChannelPrivateKey argument to the function
4057 silc_client_send_channel_message so that application can choose
4058 to use specific private ke if it wants to. If it is not provided,
4059 the normal channel key is used, unless private keys are set.
4060 In this case the first (key that was added first) is used
4061 as the encryption key.
4063 * Implemented the support for channel private key handling.
4064 Implemented the following functions:
4066 silc_client_add_channel_private_key,
4067 silc_client_del_channel_private_keys,
4068 silc_client_del_channel_private_key,
4069 silc_client_list_channel_private_keys and
4070 silc_client_free_channel_private_keys
4072 Affected file lib/silcclient/client_channel.c.
4074 * Added the support for the private keys in the channel message
4075 sending and encryption and in the message reception and
4076 decryption. Affected funtions are
4077 silc_client_send_channel_message and silc_client_channel_message.
4079 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Added SKE's key verify callback to the client library's
4082 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4084 * Removed the statement that server (or router) must send USERS
4085 command reply when joining to the channel so that the client
4086 knows who are on the channel. Instead, the client list and
4087 client's mode list is now sent in the JOIN command reply to the
4088 client who joined channel. This is better solution.
4090 * Added function silc_server_get_users_on_channel and function
4091 silc_server_save_users_on_channel to the silcd/server.[ch].
4093 * Removed function silc_server_command_send_users from the
4096 * Do not show topic on the client library anymore. The topic is
4097 sent in the command reply notify to the application and the
4098 application must show the topic now.
4100 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Added client searching by nickname hash into the IDENTIFY and
4103 WHOIS commands in the server as they were clearly missing from
4104 them. Affected file is silcd/command.c.
4106 * Fixed a bug in private message receiving in the client library.
4107 The remote ID was freed and it wasn't supposed, now it is
4110 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * Minor fix to the channel payload; allocate the data area, as it
4113 needs to be of specific length.
4115 * If the key agreement port is zero then the operating
4116 system will define the bound port. Affected files are
4117 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4119 * Added new function silc_channel_payload_decrypt into the file
4120 lib/silccore/silcchannel.[ch].
4122 * Moved the channel message etc, check from silc_packet_decrypt
4123 to applications. The library calls now a generic
4124 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4125 when the packet is either normal or special. This was done to
4126 allow more wide range of checking that was not allowed when
4127 the code was in library. Now applications can do virtually any
4128 checks to the packet and return to the library the decision how
4129 the packet should be processed. Affected files are
4130 lib/silccore/silcpacket.[ch].
4132 Added silc_server_packet_decrypt_check to the server and
4133 silc_client_packet_decrypt_check to the client library.
4135 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4136 to send with specified source and destination information.
4138 * Channel message delivery between routers was broken after the
4139 channel key distribution was fixed earlier. The channel key
4140 was used be to distributed to other routers as well which is not
4141 allowed by the protocol. Now this is fixed and channel keys
4142 really are cell specific and the channel message delivery between
4143 routers comply with the protocol specification.
4145 * Fixed various commands in server to check also the global list
4146 for the channel entry and not just the local list. The affected
4147 file silcd/command.c.
4149 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Added assert()s to buffer formatting and unformatting routines
4152 to assert (if --enable-debug) when error occurs. Affected
4153 file: lib/silcutil/silcbuffmt.c.
4155 * Changed to auto-reconnect to check whether the remote host is
4156 router and register the re-connect timeout if it is. It used
4157 to check that whether we are normal server, but router must do
4158 auto-reconnect with another router as well. Affected file
4161 * Removed the [<key len>] option from CMODE command as the cipher
4162 name decides the key length, nowadays. See the defined ciphers
4163 from the protocol specification.
4165 * Added [<hmac>] option to the CMODE command to define the HMAC
4166 for the channel. Added SILC_CMODE_HMAC channel mode.
4168 * Added [<hmac>] option for the JOIN command so that user can
4169 select which HMAC is used to compute the MACs of the channel
4172 * Added Hmac field to the Channel Message Payload. The integrity
4173 of plaintext channel messages are now protected by computing
4174 MAC of the message and attaching the MAC to the payload. The
4175 MAC is encrypted. Now, it is clear that this causes some
4176 overhead to the size of the packet but rationale for this is that
4177 now the receiver can verify whether the channel message decrypted
4178 correctly and also when private keys are set for the channel the
4179 receiver can decrypt the packet with several keys and check from
4180 the MAC which key decrypted the message correctly.
4182 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4183 lib/silccrypt/silccipher.[ch].
4185 * Added silc_hash_len to return the digest length into the
4186 lib/silcrypt/silchash.[ch].
4188 * Rewrote parts of Silc Channel Payload interface in the
4189 lib/silccore/silcchannel.[ch]. The encode function now also
4190 encrypts the packet and parse function decrypts it.
4192 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Fixed a minor formatting bug in the SKE's key material processing.
4195 It actually might have processed the keys wrong way resulting
4198 * Redefined the mandatory HMAC algorithms and added new algorithms.
4199 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4200 and hmac-md5 truncated to 96 bits. The mandatory is now
4201 hmac-sha1-96. Rest are optional (including the one that used
4202 to be mandatory). Rationale for this is that the truncated HMAC
4203 length is sufficient from security point of view and can actually
4204 make the attack against the HMAC harder. Also, the truncated
4205 HMAC causes less overhead to the packets. See the RFC2104 for
4208 * Added new [hmac] configuration section. The SKE used to use
4209 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4210 is of course wrong. The official names that must be proposed in
4211 the SKE are the ones defined in the protocol specification
4212 (hmac-sha1-96 for example). The user can configure any hmac
4213 using any hash function configured in the [hash] section. At
4214 least, the mandatory must be configured.
4216 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4218 * Added HMAC list to the SKE proposal list. It has now both
4219 hash algorithm list and HMAC list. This makes the protocol
4220 incompatible with previous versions. The SKE now seems to work
4221 the way it is supposed to work, for the first time actually.
4223 * Defined plain Hash algorithms to the protocol specification.
4226 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Implemented support for key agreement packets into the server.
4229 Added functions silc_server_key_agreement and
4230 silc_server_send_key_agreement. Other than these functions,
4231 server has nothing to do with this packet.
4233 * Added support for private message key packets into the server.
4234 Added functions silc_server_private_message_key and
4235 silc_server_send_private_message_key.
4239 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4240 called in the protocol's final callback instead in the END
4241 protocol state. This makes a little more sense and in the same
4242 time in client we can use the same protocol routines for normal
4243 key exchange and to key agreement packet handling as well.
4245 * Added to both client's and server's KE protocol context the
4246 SilcSKEKeyMaterial pointer to save the key material. We will
4247 bring the key material to the protocol's final callback by doing
4248 this. The final callback must free the key material.
4250 * Added SKE's packet_send callback into client's KE protocol
4251 context so that the caller can choose what packet sending function
4252 is used. This way we can use different packet sending when
4253 doing normal SKE when doing key agreement packet handling (in
4254 the key agreement packet handling we do not want to encrypt
4257 * Implemented the responder side of the key agreement routines
4258 in the client. The client can now bind to specified port and
4259 accept incoming key negotiation. The key material is passed
4260 to the application after the protocol is over.
4262 * Implemented the processing of incoming Key Agreement packet
4263 in the client. Added function silc_client_key_agreement to
4266 * Implemented the intiator side of the key agreement routines
4267 in the client. The client can now initiate key agreement with
4268 another remote client. The key material is passed to the
4269 application after the protocol is over.
4271 * Created client_keyagr.c to include all the key agreement
4274 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4275 SILC_TASK_CALLBACK except that it is not static.
4277 * Created client_notify.c and moved the Notify packet handling
4278 from the client.[ch] into that file.
4280 * Created client_prvmsg.c and moved all private message and
4281 private message key routines from the client.[ch] into that file.
4283 * Create client_channel.c and moved all channel message and
4284 channel private key routines from the client.[ch] into that file.
4286 * Changed silc_client_get_client_by_id_resolve to resolve with
4287 WHOIS command instead of IDENTIFY command, in the file
4288 lib/silclient/idlist.c.
4290 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Implemented the SKE's responder side to the Client library.
4294 * When FAILURE is received to the protocol do not trust it
4295 blindly. Register a timeout to wait whether the remote closes
4296 the connection as it should do it, only after that process the
4297 actual failure. This was changed to both client and server.
4299 * Added client_internal.h to include some of the structures
4300 there instead of client.h in lib/silcclient/.
4302 * Added function silc_task_unregister_by_callback to unregister
4303 timeouts by the callback function.
4305 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Some "Incomplete WHOIS info" errors has been appearing on the
4308 log files. Took away the entry->userinfo check from WHOIS
4309 reply sending. The entry->userinfo is now " " if client did not
4310 provide one. I thought this was fixed earlier but something
4311 is wrong still. Let's see if the error still appears.
4313 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Fixed a minor bug in the login when the channel key is
4316 re-generated in the server. It used to generate the key in
4317 wrong order and thus caused problems in the channel traffic.
4319 * Fixed a minor bug in channel key distsribution after
4320 KICK command. The key was not sent to the router even though
4323 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Added silc_ske_process_key_material_data as generic routine
4326 to process any key material as the SILC protocol dictates. The
4327 function is used by the actual SKE library but can be used by
4328 applications as well. This relates to the private message keys
4329 and the channel private keys since they must be processed the
4330 same way the normal SILC session keys. The protocol dictates
4331 this. Affected files: lib/silcske/silcske.[ch].
4333 Added also silc_ske_free_key_material to free the
4334 SilcSKEKeyMaterial structure.
4336 * Defined silc_cipher_set_key function to set the key for
4337 cipher without using the object's method function. The affected
4338 files: lib/silccrypt/silccipher.[ch].
4340 * Implemented silc silc_client_add_private_message_key,
4341 silc_client_add_private_message_key_ske,
4342 silc_client_del_private_message_key,
4343 silc_client_list_private_message_keys and
4344 silc_client_free_private_message_keys functions in the
4347 Added functions silc_client_send_private_message_key to send
4348 the Private Message Key payload and silc_client_private_message_key
4349 to handle incoming Private Message Key payload.
4351 * Added Cipher field to the Private Message Key payload to set
4352 the cipher to be used. If ignored, the default cipher defined
4353 in the SILC protocol (aes-256-cbc) is used.
4355 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Removed lib/silcclient/ops.h file.
4359 Redefined parts of the SILC Client Library API. Created new
4360 file silcapi.h that deprecates the ops.h file and defines the
4361 published Client Library API. Defined also private message key
4362 API and channel private key API into the file.
4364 This is the file that the application must include from the
4365 SILC Client Library. Other files need not be included by
4366 the application anymore.
4368 * Added new key_agreement client operation callback and also
4369 defined the Key Agreement library API for the application.
4371 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4374 is used by clients to request key negotiation between another
4375 client in the SILC network. If the negotiation is started it
4376 is performed using the SKE protocol. The result of the
4377 negotiation, the secret key material, can be used for example
4378 as private message key.
4380 Implemented the Key Agreement payload into the files
4381 lib/silccore/silauth.[ch].
4383 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Redefined ciphers for the SILC protocol. Added some new ciphers
4386 and defined the key lengths for the algorithms. Changed the
4387 code accordingly. The default key length is now 256 bits.
4389 * Fixed SKE key distribution function silc_ske_process_key_material
4390 when the key length is more than 128 bits. The default key
4391 length in SILC is now 256 bits.
4393 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4394 to indicate unsupported algorithm.
4396 * Renamed rijndael.c to aes.c and all functions as well.
4398 * Fixed a long standing channel key setting bug in client library.
4399 Weird that it has never surfaced before.
4401 * Fixed bug in channel deletion. If the entire channel is removed
4402 then it must also delete the references of the channel entry
4403 from the client's channel list as the client's channel entry and
4404 the channel's client entry share same memory.
4406 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Implemented CONNECT and SHUTDOWN commands in the client.
4410 * Implemented CLOSE command to the client.
4412 * Added the function silc_idlist_find_server_by_name into the
4413 files silcd/idlist.[ch].
4415 Added the function silc_idlist_find_server_by_conn into the
4416 files silcd/idlist.[ch].
4418 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * DIE command was renamed to SHUTDOWN. Updated the both code
4423 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4424 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4426 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4429 * Added function silc_server_create_connection function to create
4430 connection to remote router. My server implementation actually
4431 does not allow router to connect to normal server (it expects
4432 that normal server always initiates the connection to the router)
4433 so the CONNECT command is only good for connecting to another
4436 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4439 or some other client was kicked from the channel.
4441 Implemented the handling of the notify type to both client
4444 Implemented silc_server_send_notify_kicked to send the KICKED
4445 notify. It is used to send it to the server's primary router.
4447 * Implemented the KICK command into server and client.
4449 * Added `query' argument to the silc_idlist_get_client function
4450 to indicate whether to query the client from server or not if
4453 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4454 to indicate that the client is not channel founder.
4458 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Removed the rng context from SilcPacketContext structure and
4461 changed that the packet routine uses the Global RNG API.
4463 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * Added support for quit message that client can "leave" on the
4466 channel when it quits the SILC. It is ditributed inside the
4467 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4469 Added silc_server_free_client_data that will take the
4470 signoff message as argument.
4472 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4474 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Updated parts of the protocol specification to keep it up
4479 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4482 payloads in one packet.
4484 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4485 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4486 use now the new List flag.
4488 * Also deprecated the following packet types: REPLACE_ID,
4489 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4491 * Added list support for Notify packet in server.
4493 * Added silc_server_send_notify_channel_change to send the
4494 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4495 the silc_server_send_replace_id.
4497 * Added silc_server_send_notify_nick_change to send the
4498 NICK_CHANGE notify type. Deprecates the function
4499 silc_server_send_replace_id.
4501 * Added silc_server_send_notify_join to send the JOIN notify type.
4502 Deprecates the function silc_server_send_new_channel_user.
4504 * Added silc_server_send_notify_leave to send LEAVE notify type.
4505 Deprecates the function silc_server_send_remove_channel_user.
4507 * Added silc_server_send_notify_cmode and
4508 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4509 types. Deprecates the silc_server_send_set_mode function.
4511 * Added SERVER_SIGNOFF notify type to indicate that server has
4512 quit. This means that all clients on the channel from that
4513 server will drop. This can be also used when netsplit happens.
4515 Deprecated REMOVE_ID packet type since it is not needed anymore
4518 Added silc_server_send_notify_server_signoff to send the
4519 SERVER_SIGNOFF notify type. Deprecates the function
4520 silc_server_send_remove_id.
4522 Added also silc_server_send_notify_signoff to send the
4523 SIGNOFF notify type.
4525 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4526 SILC protocol from this day on. Changed the protocol
4527 specification as well.
4529 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4530 notify type. It is used between routers to notify about
4531 topic changes on a channel.
4533 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4536 * Partly updated the protocol specification to comply with the
4537 changes now made. It is still though a bit outdated.
4539 * The JOIN notify type now takes one extra argument <Channel ID>.
4540 The packet used to be destined to the channel but now the
4541 JOIN type may be sent as list thus it is impossible to
4542 destine it to any specific channel. By adding this argument
4543 it is again possible.
4545 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Added CREDITS file. The CHANGES and CREDITS file will appear
4548 in the distribution as well.
4550 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4553 types in the server's silcd/packet_receive.c.
4555 * Implemented CMODE and CUMODE to work in router environment.
4557 * Fixed minor encoding and decoding buglet from the
4558 lib/silccore/silcmode.c.
4560 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4563 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4565 * Changed all SilcConfigServer* and silc_config_server* to
4566 SilcServerConfig* and silc_server_config*, respectively.
4569 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Associated the ID (client or server ID) to the Authentication
4572 Payload to avoid any possibility of forging. Updated the
4573 protocol specification and the code accordingly.
4575 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * The RSA key length is now save to the RsaKey context in the
4578 key generation process in lib/silccrypt/rsa.c. The key length
4579 is now used to figure out the maximum size of the block allowed
4580 to be encrypted/signed.
4582 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4583 is equivalent to the silc_mp_mp2bin but does not allocate any
4586 * Changed silc_mp_mp2bin API to take length argument. If it is
4587 non-zero then the buffer is allocated that large. If zero, then
4588 the size is approximated using silc_mp_sizeinbase, which however
4591 * Created Global RNG API which is global RNG that application can
4592 initialize. After initializing, any routine anywhere in the
4593 code (including library) can use RNG without allocating a new
4594 RNG object. This was done to allow this sort of use of the
4595 RNG in code that has no chance to allocate RNG object. All
4596 applications currently allocate this and many routines in the
4597 library use this. Affected file lib/silccrypt/silcrng.[ch].
4599 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4600 it to use the Global RNG API.
4602 * Defined Authentication Payload into protocol specification that
4603 is used during SILC session to authenticate entities. It is
4604 used for example by client to authenticate itself to the server
4605 to obtain server operator privileges.
4607 Implemented this payload into the lib/silccore/silcauth.[ch].
4608 Implemented also routines for public key based authentication
4609 as the new protocol specification dictates.
4611 Moved definitions of different authentication methods from
4612 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4614 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4615 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4616 silc_pkcs_verify_with_hash functions into the file
4617 lib/silccrypt/silcpkcs.[ch].
4619 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * The client entry's userinfo pointer must be always valid.
4622 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4623 will fail since it requires the userinfo. Now, the userinfo
4624 is allocated as "" if actual userinfo does not exist. Actually,
4625 it must exist and it is totally Ok to drop client connections
4626 that does not announce the userinfo. However, we will make
4627 this workaround for now.
4629 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4630 to return the remote port by socket.
4632 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4635 SILC_SERVER_PENDING_EXEC and added an new macro
4636 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4637 data or when error occurs while processing the pending command.
4639 Added new argument `destructor' into silc_server_command_pending
4640 and to the SilcServerCommandPending object. This destructor is
4641 now called after calling the pending callback or if error occurs
4642 immediately. If error occurs the actual pending callback won't
4643 be called at all - only the destructor. The destructor may be
4644 NULL if destructor is not needed.
4646 All this applies for client library code as well. Similar
4647 changes were made there as well for the pending commands.
4649 In the client, the application must now allocate the
4650 SilcClientCommandContext with the silc_client_command_alloc
4653 * Added reference counter to the SilcServerCommandContext. Added
4654 function silc_server_command_alloc and silc_server_command_dup
4657 Same type of functions added to the client library for the same
4660 * Removed the cmd_ident from IDListData away since it is now
4661 global for all connections. It is the command identifier used
4662 in command sending and with pending commands. The affected file
4665 * Added reference counter to the SilcSocketConnection objecet to
4666 indicate the usage count of the object. The object won't be
4667 freed untill the reference counter hits zero. Currently only
4668 server uses this, and client ignores it. The client must be
4669 set to use this too later. The affected files are
4670 lib/silccore/silcsockconn.[ch]. Added also the function
4671 silc_socket_dup to increase the reference counter.
4673 This was mainly added because it is possible that the socket
4674 is removed underneath of pending command or other async
4675 operation. Now it won't be free'd and proper DISCONNECTING
4676 flags, etc. can be set to avoid sending data to connection that
4677 is not valid anymore.
4679 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4680 the connection. After that it sets SILC_SET_DISCONNECTED.
4681 It is, however, possible that the socket data is not still freed.
4682 The silc_server_packet_process now checks that data is not
4683 read or written to connection that is DISCONNECTED. The socket
4684 get's freed when the reference counter hits zero.
4686 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Changed the client operation API: channel_message operation's
4689 `sender' is now the client entry of the sender, not the nickname
4690 and the `channel' is the channel entry, not the channel name.
4692 In the private_message operation the `sender' is now also the
4693 client entry of the sender not the nickname.
4695 Affected file is lib/silcclient/ops.h and all applications
4696 using the client operations.
4698 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Moved the calling of ops->connect() from connect_to_server_final
4701 into receive_new_id functin since that is the point when the
4702 client is actually allowed to send traffic to network. The
4703 affected file is lib/silcclient/client.c.
4705 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4708 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4709 (if needs broadcasting) instead of broadcasting the packets one
4710 by one which would make a burst in the network traffic.
4712 * Added `broadcast' argument to the functions in silcd/server.[ch]
4713 silc_server_create_new_channel[_with_id] to indicate whether
4714 to send New Channel packet to primary router.
4716 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Added new function into the silcd/server.[ch] files:
4719 silc_server_create_new_channel_with_id to create new channel with
4720 already existing Channel ID.
4722 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4723 lib/silccore/silcpacket.h. This packet is used t send list of
4724 Set Mode payloads inside one packet. Server uses this to set
4725 the modes for the channels and clients on those channels, that it
4726 announced to the router when it connected to it. The protocol
4727 specification has been updated accordingly.
4729 * The silc_server_new_channel did not handle the packet coming
4730 from normal server as it normally does not send that. However,
4731 when it announces its channels it does send it. Implemented
4732 the support for that.
4734 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4735 into the file lib/silccore/id.h.
4737 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Fixed memory leaks in the functions silc_idlist_del_client,
4740 silc_idlist_del_channel and silc_idlist_del_server in the file
4741 silcd/idlist.c. All of those leaked like a sieve.
4743 * Fixed some small memory leaks in the client's function
4744 silc_client_notify_by_server.
4746 * Added functions into silcd/server.c: silc_server_announce_clients,
4747 silc_server_announce_channels and silc_server_announce_server.
4748 These functions are used by normal and router server to announce
4749 to its primary router about clients, channels and servers (when
4750 router) that we own. This is done after we've connected to the
4753 These functions effectively implements the following packet types:
4754 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4755 and SILC_PACKET_NEW_ID_LIST.
4757 * Added new functions into the silcd/packet_receive.[ch]:
4758 silc_server_new_id_list, silc_server_new_channel_list and
4759 silc_server_new_channel_user_list to handle the incoming
4760 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4762 * Added support of changing Channel ID in the function
4763 silc_server_replace_id. If the server that announces a channel
4764 to the router already exists in the router (with same name but
4765 with different Channel ID), router is responsible to send
4766 Replace ID packet to the server and force the server to change
4767 the Channel ID to the one router has.
4769 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4770 client that the Channel ID has been changed by the router. The
4771 normal server sends this to the client. Client must start using
4772 the new Channel ID as the channel's ID.
4774 Implemented handling of this new type into lib/silcclient/client.c
4775 into the function silc_client_notify_by_server.
4777 * Added new function silc_idlist_replace_channel_id into the files
4778 silcd/idlist.[ch] to replace the Channel ID.
4780 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Call silc_server_command_identify_check always when processing
4783 the IDENTIFY command in silcd/command.c
4785 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4788 send keepalive packets. The packet can be sent by clients,
4789 servers and routers.
4791 Added function silc_socket_set_heartbeat into the file
4792 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4793 If not set, the heartbeat is not performed. The actual
4794 heartbeat is implemented in the low level socket connection
4795 library. However, application is responsible of actually
4798 Added silc_server_send_heartbeat to send the actual heartbeat
4799 packet into silcd/packet_send.[ch]. Server now performs
4800 keepalive with all connections.
4802 * Added silc_task_get_first function into lib/silcutil/silctask.c
4803 to return the timeout task with shortest timeout. There was a bug
4804 in task unregistration that caused problems. TODO has been
4805 updated to include that task system must be rewritten.
4807 * The client library will now resolve the client information when
4808 receiving JOIN notify from server for client that we know but
4809 have incomplete information.
4811 * Rewrote parts of silc_server_remove_from_channels and
4812 silc_server_remove_from_one_channel as they did not remove the
4813 channel in some circumstances even though they should've.
4815 * Encryption problem encountered in server:
4817 The LEAVE command used to send the Channel Key packet to the
4818 router immediately after generating it. However, the code
4819 had earlier sent Remove Channel user packet but not immediately,
4820 ie. it was put to queue. The order of packets in the router
4821 was that Channel Key packet was first and Remove Channel User
4822 packet was second, even though they were encrypted in the
4823 reverse order. For this reason, MAC check failed. Now, this
4824 is fixed by not sending the Channel Key packet immediately but
4825 putting it to queue. However, this is more fundamental problem:
4826 packets that are in queue should actually not be encrypted
4827 because packets that are sent immediately gets encrypted
4828 actually with wrong IV (and thus MAC check fails). So, packets
4829 that are in queue should be encrypted when they are sent to
4830 the wire and not when they put to the queue.
4832 However, the problem is that the current system has not been
4833 designed to work that way. Instead, the packet is encrypted
4834 as soon as possible and left to the queue. The queue is then
4835 just purged into wire. There won't be any fixes for this
4836 any time soon. So, the current semantic for packet sending
4839 o If you send packet to remote host and do not force the send
4840 (the packet will be in queue) then all subsequent packets to the
4841 same remote host must also be put to the queue. Only after the
4842 queue has been purged is it safe again to force the packet
4845 o If you send all packets immediately then it safe to send
4846 any of subsequent packets through the queue, however, after
4847 the first packet is put to queue then any subsequent packets
4848 must also be put to the queue.
4850 Follow these rules and everything works fine.
4852 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Added new function silc_server_remove_clients_by_server to
4855 remove all client entries from ID list when the server connection
4856 is lost. In this case it is also important to invalidate all
4857 client entires as they hold the invalid server entry. This
4858 fixes fatal bug when server has lost connection and will reconnect
4861 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Made some sanity checks to silc_server_daemonise like to check
4864 whether the requested user and group actually exists.
4866 * Added sanity check to SKE's silc_ske_responder_finish to check
4867 that the public and private key actually is valid.
4869 * Invalidate the client's nickname when receiving Replace ID
4870 packet and the Client ID is being replaced. This means that the
4871 server will query the nickname if someone needs it (client)
4874 * Sort the ID Cache in client library when the ID Cache data
4875 has changed (needs sorting).
4877 * Do not allow for SILC client to create several connections to
4878 several servers. The client does not support windows right now
4879 and generating multiple connections causes weird behaviour.
4881 Irssi-silc client does support windows and can handle several
4882 connections without problems, see: www.irssi.org and SILC plugin.
4884 * Fixed some places where client was added to the IDList. The
4885 rule of thumb is following (in order to get everything right):
4886 If the client is directly connected local client then the
4887 `connection' argument must be set and `router' argument must be
4888 NULL to silc_idlist_add_client function. If the client is not
4889 directly connected client then the `router' argument must
4890 bet set and the `connection' argument must be NULL to the
4891 silc_idlist_add_client function.
4893 * The funtion silc_server_packet_send_local_channel actually did
4894 not check whether the client was locally connected or not. It
4895 does that now. Fixed a bug related to LEAVE command.
4897 * Fixed Remove Channel User payload parsing bug in server's
4898 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4900 * The server's silc_server_save_channel_key now checks also the
4901 global ID list for the channel as it might not be in the local
4902 list. Fixed a bug related to LEAVE command.
4904 * Is this the end of the [<unknown>] buglet that has been lurking
4905 around for a long time? A little for loop fix in server's
4906 silc_server_command_whois_parse that is used by both IDENTIFY
4907 and WHOIS command. At least, this was a clear bug and a cause
4908 of one type of [<unknown>] buglet.
4910 * WHOIS and IDENTIFY commands call the function
4911 silc_server_command_[whois/identify]_check function even if
4912 we are not router server.
4914 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added --with-gmp configuration option. If set the GMP
4917 is always compiled in the SILC source tree. If not set then
4918 it is checked whether the system has the GMP3 installed. If
4919 it has then the GMP won't be compiled (the system's headers
4920 and library is used), if it doesn't have it then the GMP is
4921 compiled in the SILC source tree.
4923 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Changed RSA private exponent generation to what PKCS #1
4926 suggests. We try to find the smallest possible d by doing
4927 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4928 not security fix but optimization.
4930 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Added new config entry [Identity] to fork the server and run
4933 it as specific user and group. A patch from Bostik.
4935 * Imported Dotconf configuration library into lib/dotconf.
4936 This will be used to create the SILC configuration files later.
4937 It will appear in the distsribution after this commit.
4939 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * A big code auditing weekend happening. Auditing code for
4942 obvious mistakes, bugs and errors. Also, removing any code
4945 Removed files for being obsolete:
4947 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4948 inline in the file lib/silcutil/silcbuffer.h)
4950 o lib/silcutil/silcbufutil.c (the header has inline versions)
4952 Changed code to fix possible error conditions:
4954 o The buffer formatting routines now check that the destination
4955 buffer really has enough space to add the data. This applies for
4956 both buffer formatting and unformatting
4957 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4958 unformatting was changed to accomodate following rules:
4959 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4960 sent to the function while XXX_*STRING will not allocate or copy
4961 the data into the buffer. Instead it sets the pointer from the
4962 buffer into the pointer sent as argument (XXX_*STRING used to
4963 require that the pointer must be allocated already). This change
4964 makes this whole thing a bit more consistent and more optimized
4965 (note that the data returned in the unformatting with XXX_*STRING
4966 must not be freed now). The routines return now -1 on error.
4968 o Tried to find all code that use buffer_format and buffer_unformat
4969 and added return value checking to prevent formatting and
4970 especially unformatting errors and possible subsequent fatal
4973 o Changed ske->x and ske->KEY to mallocated pointers in
4974 lib/silcske/silcske.h. Fixed possible data and memory leak.
4976 o Added return value checking to all *_parse* functions. Fixed
4977 many memory leaks as well.
4979 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4980 so that buffer overflows would not happen. All code now also
4981 checks the return value as it can fail.
4983 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added reconnection support to server if the normal server looses
4986 its connection to the router (for example if router is rebooted).
4987 The server performs normal reconnection strategy implemented
4988 to the server. Affected file silcd/server.c.
4990 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added new packet type SILC_PACKET_SET_MODE that is used to
4993 distribute the information about changed modes (for clients,
4994 channels and clients channel modes) to all routers in the
4995 network. Updated the protocol specification accordingly.
4997 Added functions into silcd/packet_send.c and
4998 silcd/packet_receive.c: silc_server_send_set_mode,
4999 silc_server_set_mode.
5001 Added new files silcmode.[ch] into lib/silccore that implements
5002 the encoding and decoding of Set Mode Payload. Added new type
5003 SilcSetModePayload. Moved the definitions of different modes
5004 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5006 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Oops, a little mistake in server's connection authentication
5009 protocol. The protocol is not ended with FAILURE but with
5010 SUCCESS if the authentication is Ok. :) Affected file is
5013 * Implemented NICK_CHANGE notify handling in server in the file
5014 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5015 the local clients on the channel. After the changing nickname
5016 in router environment snhould work and the [<unknown>] nickname
5017 should appear no more.
5019 The silc_server_replace_id function that receives the Replace ID
5020 payload now sends the NICK_CHANGE notify type also in the file
5021 silcd/packet_receive.c
5023 * Changed WHOIS and IDENTIFY command to support the maximum amount
5024 of arguments defined in protocol specs (3328 arguments). This
5025 fixed a bug that caused problems when there were more than three
5028 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added extra parameter, command identifier, to the
5031 silc_client_send_command so that explicit command identifier
5034 Changed that ID list routines uses specific command identifier
5035 when sending WHOIS/IDENTIFY requests to the server so that they
5036 can be identified when the reply comes back.
5038 Affected files lib/silcclient/command.[ch],
5039 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5041 * Added `sender' argument to silc_server_packet_send_to_channel
5042 to indicaet the sender who originally sent the packet to us
5043 that we are now re-sending. Ignored if NULL. Affected file
5044 silcd/packet_send.[ch].
5046 * Added some server statistics support in silcd/server_internal.h
5047 SilcServerStatistics structure and around the server code. Also
5048 send some nice statistics information when client is connecting
5051 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Fixed channel ID decoding in server's JOIN command reply in
5054 silcd/command_reply.c
5056 * Fixed braodcasting of replace ID payload to not to send it if
5057 we are standalone server in silcd/packet_receive.c.
5059 * Fixed all channel message sending routines to not to send
5060 packets to clients that has router set, since they are routed
5061 separately in the same function earlier. Affects file
5062 silcd/packet_send.c and all channel packet sending functions.
5064 * In USERS reply, res_argv[i] are not allocated, the table
5065 is allocated. Thus changed that free the table, not its
5068 * In server's whois_check and identify_check if the client is
5069 locally connected do not send any WHOIS commands - they are not
5072 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Fixed some minor bugs in client when sending WHOIS command. The
5075 arguments was in wrong order.
5077 * Removed statis function add_to_channel from server in
5078 silcd/command.c that was previously used with the joining but
5081 * Tested USERS command in router environment successfully with two
5082 routers, two servers and two clients.
5084 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Reorganized the USERS command and command reply in client library
5087 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5088 When the command is given by user we register a pending command
5089 callback that will reprocess the command after the reply has been
5090 received from the server. When reprocessing the packet we then
5091 display the information. Thus, the USERS information is displayed
5092 now in the command callback instead of in the command reply
5093 callback. The processing of the command is same as previously
5094 when server has sent the command reply in the JOINing process.
5096 * Added to USERS command in silcd/command_reply.c to join the client,
5097 we didn't use to know about, to the channel after we've created
5098 a client entry for it. Also, for clienet we did know already still
5099 check whether it is on the channel or not and add it if not.
5101 * Removed silc_server_command_join_notify as the function and its
5104 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Changed the client's pending command handling to the same as the
5107 server's pending command handling. It is also now possible to
5108 execute command reply functions from other command reply
5109 function as the function callbacks for commands and command
5110 replies are one and same. The pending commands are not static
5111 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5112 in client connection context. Thus, pending commands are server
5113 connection specific as it is convenient.
5115 Changed the function silc_client_command_pending and
5116 silc_client_command_pending_del and added new function
5117 silc_client_command_pending_check. Removed the
5118 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5121 * Added cmd_ident, current command identifier, to the client
5122 connection context in lib/silcclient/client.h to keep track on
5123 command identifiers used in command sending. Client's command reply
5124 function handling now supports the mandatory command identifiers.
5126 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5127 funtions in client to fully support pending command callbacks.
5129 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5130 as one of the arguments to the application in the command reply
5133 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5134 before first releasing SILC but came back. Now it is removed again
5135 and should come back nomore. The FORWARDED flag was used only
5136 by the JOINing procedure by forwarding the command packet to router.
5137 Now, the JOINing procedure has been changed to more generic (due
5138 to various router environment issues) and FORWARDED is not needed
5139 anymore for anything. The protocol specification is yet to be
5142 Now, removed silc_server_packet_forward from server and the flag
5143 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5145 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Renamed NAMES command to USERS command. The NAMES was named that
5148 due to historical reasons. Now it is renamed. Also, rewrote
5149 parts of the USERS command. The nickname list is not sent anymore
5150 by the server. Only Client ID and mode lists are sent in the USERS
5151 command. Changed this also to the protocol specification.
5153 The client now resolves the names and stuff after it receives
5154 the USERS list from the server when joining to the channel.
5156 * WHOIS and IDENTIFY commands has been changed to support multiple
5157 Client ID's per command. One can now search for multiple users
5158 in the network by sending only one WHOIS or IDENTIFY command.
5159 Changed the code and the protocol specifications.
5161 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5162 uses silc_server_command_whois_parse to parse the request. */
5164 * If normal server, do not parse the WHOIS and IDENTIFY requests
5165 before sending it to the router. Saves some time.
5167 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Fixed JOIN command on client library. Wrong number of arguments
5170 used to crash the client.
5172 * Added silc_server_channel_has_global function to check whether
5173 channel has global users or not.
5175 * Added silc_server_channel_has_local function to check whether channel
5176 has locally connected clients on the channel.
5178 * The silc_server_remove_from_one_channel now checks whether the
5179 channel has global users or not after given client was removed from
5180 the channel. It also checks whether the channel has local clients
5181 on the channel anymore. If it does not have then the channel entry
5182 is removed as it is not needed anymore.
5184 * The silc_server_notify now checks on JOIN notify whether the joining
5185 client is one of locally connected or global. If it is global then
5186 the channel has now global users on the channel and that is marked
5187 to the channel entry. Also, it now saves the global client to
5188 global list who is joining and JOINs it to the channel. This is
5189 for normal server, that is.
5191 Changed silc_server_send_notify_on_channel,
5192 silc_server_packet_relay_to_channel and
5193 silc_server_packet_send_to_channel check if we are normal server
5194 and client has router set (ie. global client) do not send the
5195 message to that client, as it is already routed to our router.
5197 * Implemented LEAVE notify type handling in silc_server_notify
5200 * Tested LEAVE command in router environment successfully. Tested
5201 with two routers, two servers and two clients.
5205 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5207 * Implemented SIGNOFF notify type handling in silc_server_notify
5210 * silc_server_remove_id now removes the client entry from all channels
5211 it has joined and thusly sends SIGNOFF notify type.
5213 * Rewrote the NAMES list generation in server by removing two excess
5214 loops. The lists are created now inside one loop.
5216 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * silc_server_remove_channel_user checks now also global list
5219 for channel and client.
5221 * silc_server_new_channel_user checks now both local and global
5222 list for channel and client. Fixed a bug in client id decoding.
5223 Used to decode wrong buffer.
5225 * silc_server_channel_message checks now both local and global
5226 list for channel entry.
5228 * Tested channel joining (hence JOIN) in router environment
5229 successfully. Tested with two routers, two servers and two
5232 * Tested channel message sending in router environment successfully.
5234 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added silc_server_save_channel_key into server.[ch] to save the
5237 received channel key in Channel Key payload processing. It is
5238 also used in JOIN command reply handling.
5240 Equivalent function silc_client_save_channel_key added into
5241 client.[ch] into client library.
5243 * Changed JOIN command reply to send information whether the channel
5244 was created or not (is existing already) and the channel key
5245 payload. Changed protocol specs accordingly.
5247 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5248 the request was sent by ID and not by nickname. Crashed on
5251 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5254 now correctly save the received data.
5256 * silc_server_free_sock_user_data now notifies routers in the
5257 network about entities leaving the network.
5259 At the same time implemented functions silc_server_remove_id
5260 and silc_server_send_remove_id to receive and send REMOVE_ID
5261 packets. The packet is used to notify routers in the network
5262 about leaving entities. The ID removed will become invalid in
5265 * Added function silc_idlist_del_server into server. Removes and
5266 free's server entry from ID list.
5268 * silc_server_private_message function now checks, if we are router,
5269 that the destination ID really is valid ID, naturally.
5271 * In router when NEW_ID packet is received (for new client) the
5272 hash of the Client ID is saved in the ID Cache but the
5273 client->nickname is set to NULL, instead of putting the hash
5276 IDENTIFY command now also checks that client->nickname must be
5277 valid. If it is not if will request the data from the server who
5278 owns the client. Added new function
5279 silc_server_command_identify_check.
5281 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5282 to set the command to already allocated Command Payload.
5284 * Tested private message sending in router environment with two
5285 routers, two servers and two clients. Fixed minor bugs and now
5288 * Fixed segfault from client's NAMES command. Used to crash if
5291 * Forwarded packets must not be routed even if it is not destined
5292 to the receiver. Changed server code comply with this.
5294 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Added `require_reverse_mapping' boolean value to ServerParams
5297 structure. If TRUE (not default) the server will require that
5298 the connecting host has fully qualified domain name.
5300 If the reverse mapping is not required and hostname could not be
5301 found the IP address is used as hostname.
5303 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Implemented version string checking to both client and server.
5306 The check is incomplete currently due to the abnormal version
5307 strings used in development version of SILC.
5309 * Changed all command functions in server to use the new
5312 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Changed char *data to unsigned char *data in ID Cache system to
5315 support binary data as ID Cache data. Changed code to support
5316 binary data in lib/silccore/idcache.c.
5318 * Renamed silc_server_packet_relay_command_reply to
5319 silc_server_command_reply as it is normal packet receiving
5320 function. Rewrote the function to accept command replys for
5321 servers and not only for clients.
5323 * Mark remote router always as registered server if we are connecting
5324 to it. Otherwise, commands sent by the router to us are ignored.
5326 * All ID List find routines now returns the ID Cache Entry pointer
5327 as well if requested.
5329 * WHOIS command works now in router environment, tested with two
5330 routers, two servers and two clients.
5332 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5333 in router environment (as it is almost equivalent to WHOIS) but
5334 hasn't been tested thoroughly. Added new functions:
5336 silc_server_command_identify_parse
5337 silc_server_command_identify_send_reply
5338 silc_server_command_identify_from_client
5339 silc_server_command_identify_from_server
5341 * Disabled route cache adding because adding two different ID's with
5342 same IP replaces the old cache entry thus giving wrong route.
5343 The entry->router->connection is always the fastest route anyway
5344 so route cache may not be needed. Of course, new routes maybe
5345 established after receiving the ID when the entry->router->connection
5346 might not be anymore the most optimal.
5348 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Add route cache for received ID for fast routing.
5352 * Added silc_server_packet_route to route received packet on router
5353 that is not destined to us.
5355 * Renamed silc_server_get_route to silc_server_route_get.
5357 * Added id_string and id_string_len fields into SilcServer to
5358 include encoded ServerID for fast comparing without excess
5359 encoding of the ID's.
5361 * Cleaned up WHOIS command on server side. Added following static
5364 silc_server_command_whois_parse
5365 silc_server_command_whois_check
5366 silc_server_command_whois_send_reply
5367 silc_server_command_whois_from_client
5368 silc_server_command_whois_from_server
5370 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5371 arguments in command replies. All command functions should be
5372 updated to use this macro.
5374 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Minor typo fixes on command reply handling on server.
5378 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added silc_server_command_add_to_channel internal routine to add
5381 the client to the channel after router has created the channel and
5382 sent command reply to the server.
5384 * Added generic silc_server_send_command to send any command from
5387 * Use static buffer with ID rendering instead of duplicating data.
5389 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Fixed a channel user mode bug when joining to a channel server gave
5392 everybody channel founder rights, oops.
5394 * We mark ourselves as the router of the incoming server connection
5395 if we are router ourselves. This way we can check in some packet
5396 sending functions whether it is locally connected server. For
5397 incoming router connections we put NULL.
5399 * For router sending packets locally means now always sending the
5400 packet cell wide; to local clients and local servers. For normal
5401 server sending packet locally means sending it to only local
5404 * Fixed the JOIN command to really work in router environment. If the
5405 channel is created it is always created by the router. Router is
5406 also responsible of making the initial joining to the channel,
5407 sending JOIN notify to the sending server and distributing
5408 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5409 does not exist server doesn't do anything else but forward the
5410 command to the router which performs everything.
5412 * Added silc_server_send_channel_key function to send the Channel Key
5415 * Added silc_server_create_channel_key to create new channel key. The
5416 channel key is now re-generated everytime someone joins or leaves
5417 a channel, as protocol dictates. Note: channel->key_len is the
5420 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5423 packet_receive.[ch] to separate packet sending and receiving
5424 routines. The server.[ch] now includes everything else including
5425 actual packet processing (writing and reading data) and other
5428 Renamed silc_server_private_message_send_internal to
5429 silc_server_send_private_message. The routine is still though
5430 used only to relay private messages as server does not send
5431 private messages itself.
5433 Renamed silc_server_new_channel to silc_server_create_new_channel
5434 and added new function sicl_server_new_channel that handles the
5435 incoming New Channel packet. Added also new sending function
5436 silc_server_send_new_channel to send New Channel Payload.
5438 * Added new function silc_server_notify to process incoming notify
5439 packet to the server/router. Server may then relay the notify
5440 to clients if needed.
5442 * Added new function silc_server_new_channel_user to process incoming
5443 New Channel User packet. Router will redistribute the packet and
5444 send JOIN notify to its local clients and locally connected servers
5445 if needed. Normal server will send JOIN notify to its local client
5446 on same channel when received this packet. Added also corresponding
5447 sending function silc_server_send_new_channel_user to sent the
5450 * Added boolean route argument to send_notif_to_channel and
5451 packet_send_to_channel functions to attempt to route the packet
5452 if it is TRUE and send only locally if it is FALSE.
5454 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * silc_server_replace_id now broadcasts the received replace ID
5457 packet if it is not broadcast packet already. The router must
5458 broadcast to inform other routers about changed ID.
5460 * Added backpointer to server's router into SilcServer context in
5461 silcd/server_internal.h.
5463 * Fixed silc_server_packet_broadcast to send correct broadcast
5466 * The channel key is now distributed to the local client as soon
5467 as it is received from the router (in router environment) so that
5468 no other packet may be sent for the channel until client has
5471 * silc_server_remove_channel_user now broadcasts the received
5472 Remove Channel User packet if it is not broadcast packet already.
5473 The router must broadcast to inform other routers about removed
5476 * Added users field into SilcPacketContext that is a reference count
5477 of the context. One can increase the reference count by calling
5478 silc_packet_context_dup which is now changed to just increase the
5479 reference count instead of duplicating the data. The reference
5480 count is decresed by calling silc_packet_context_free that will
5481 free the data after the reference count hits zero.
5483 For now on the packet context and everything allocated into it
5484 (including the raw packet from network) must be freed by calling
5485 the new silc_packet_context_free function. Added also new function
5486 silc_packet_context_alloc that must be used now to allocate the
5487 context. This also means that if a routine is asynchronous from
5488 silc_[client/server]_packet_parse_type the packet context must
5489 be duplicated by calling silc_packet_context_dup. Otherwise it
5490 gets free'd after silc_[client/server]_packet_parse_type returns.
5491 Also, one must remember that if packet is duplicated then its
5492 reference count must be decresed by calling the free function as
5493 many times as it was duplicated.
5495 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5496 from both client and server.
5498 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Made joining to a channel working in router environment.
5502 * Cleaned up JOIN command on server side and create function
5503 silc_server_command_join_channel internal routine to make the
5506 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Changed silc_command_pending list to SilcDList. Also, added
5509 `ident' field to SilcServerCommandPending structure to identify
5510 the reply and to call correct callback.
5512 Added silc_server_command_pending_check function to replace the
5513 corresnponding macro. The silc_command_pending list is not
5516 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5517 to set identifier to previously allocated Command Payload. It
5518 is used to set identifier for command when resending Command
5521 * Added silc_command_payload_encode_payload to encode Command
5522 Payload buffer from SilcCommandPayload structure.
5524 * Added silc_argument_payload_encode_payload to encode Argument
5525 payload buffer from SilcArgumentPayload structure.
5527 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Changed WHOIS command to support router connection on server side.
5530 The whois request is always sent to router unless the server is
5531 standalone server. After server has received the reply from the
5532 router will it send the reply to the client.
5534 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5535 broadcast received broadcast packet. The function is used only
5536 by router. The broadcast packet is always sent to the router's
5539 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5540 render given ID to printable string, for log files for example.
5542 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Made basic router to router connections working. At least they
5545 can now connect to each other but nothing really works the way
5546 they are supposed - yet.
5548 * Added new initiator token to RouterConnection configuration
5549 file in silcd/serverconfig.[ch]. It is used to tell whether we
5550 are the initiator to the remote router or whether we'll expect
5551 the other end to connect.
5553 * Moved registering of listener task to silc_server_init, hence
5554 the server starts listenning as soon as it is run, even if it
5555 does not have connections to other routers. Let's see how well
5558 * Changed default connection retry timeouts for more suitable in
5561 * Removed cipher and such arguments from silc_idlist_add_client
5562 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5563 Added new function silc_idlist_add_data to add the keys and stuff
5566 * Added SilcIDListData structure and added it to SilcClientEntry
5567 and SilcServerEntry as their first field in the structure. This
5568 way we can explicitly cast the ID entries to the SilcIDListData
5569 structure and get common data for the entries. In past, we had
5570 to first check what type of connection it is and then cast it to
5571 correct ID entry type. Now, we can directly cast the opaque
5572 pointer to the SilcIDListData (no matter what ID entry it actually
5573 is) and get the data needed.
5575 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5578 in some circumstances even if threre were timeout tasks, though not
5579 IO tasks, but tasks anyway. Now fixed.
5581 * Defined SilcServerConnection structure to hold connection specific
5582 stuff about directly connected servers and routers. The definition
5583 is currently in silcd/server_internal.h. I thought about having
5584 a bit more important role fro this struct but for now it is used
5585 only when connecting to other server (or router actually).
5587 * Added connecting retry support in server when connecting to
5588 router(s). The retry feature implement exponential backoff
5589 algorithm. Also, added SilcServerParams structure to hold default
5590 parameters for server. For now, it include these retry settings
5591 and are hard coded. After server is moded to be as Silc Server
5592 Library this structure will be more important.
5594 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Changed client librarys channel->clients table to SilcList and
5597 changed code accordingly.
5599 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Changed client's channel table to SilcList and changed code
5602 accordingly. Also changed SilcChannelClientEntry to include back-
5603 pointer to the channel so that client entry can use that structure
5604 as list as well and we have fast cross-reference to the channel.
5605 This change dramatically decreased the complexity of channel
5606 handling with client entry and vice versa (removed one extra
5607 loop when searching for channel entry from many functions).
5609 * Changed server->sim from table to SilcDList and changed code
5612 * NAMES command can now be used from user interface. It will show
5613 the user list on the channel, neatly.
5615 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5616 Code now saves realname of the user if it becomes available.
5618 * Renamed configure.in to configure.in.pre and made ./prepare
5619 script to automatically add correct version string to
5620 configure.in which it creates from configure.in.pre.
5622 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * NAMES command reply now shows users mode with the nickname when
5627 * Moved silc_client_ch[u]mode[_char] functions from
5628 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5629 place sucks, they are utility functions and should be in some
5632 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5634 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5637 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Added TRQ (efficient deque and list library) into lib/trq. This is
5642 a very good list library that is currently used in the SILC. Defined
5643 SilcList API over the library because I didn't like the API very
5644 much. See lib/trq/silclist.h for the API and examples of how to
5645 use the API. Fixed various places in the code to use the new
5646 SilcList API. The SilcList is meant for lists that has a structure
5647 already defined as a list. It is not suitable to add just some
5648 context to the list (in TRQ, the context is the list actually).
5650 So, I defined SilcDList that can be used for the purpose where
5651 predefined list structure does not exit. This can be used as
5652 such list. Now some context just can be added to the SilcDList.
5653 Currently this list is not used in the SILC just yet, though there
5654 are a lot places where this can replace dynamically allocated
5655 tables and I will fix these places, later, to use SilcDList.
5656 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5657 and use TRQ internally).
5659 Also fixed some annoying warning messages that the original TRQ
5660 code generated. Also minor changes to TRQ's Makefile.in.
5662 * Added support for querying by Client ID to both WHOIS and
5663 IDENTIFY commands into server, as required by the protocol.
5665 * Removed method function pointers from SilcBuffer structure. They
5666 weren't used to anything and just increased the context size for
5667 no good reason. This change also made silc_buffer_alloc and
5668 silc_buffer_free functions inline functions.
5670 * Disabled command flooding detection support until it's fixed so
5671 that it accepts commands in but does not execute them more than once
5674 * Added silc_net_localhost(), to return local hostname, into
5675 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5676 that must be initialized before calling silc_client_init.
5678 * Added new function: silc_server_send_notify_on_channels to send
5679 notify messages to all channels client has joined. It is assured
5680 that the message is sent only once per client.
5682 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5683 lib/silcutil/silcutil.[ch] as silc_format function. The new
5684 function is generic and is used by server as well, not only by
5685 the logging routines.
5687 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5688 the provided version string was not acceptable. Added new function:
5689 silc_ske_check_version into lib/silcske/silcske.h. The function
5690 must be implemented by the application (client or server) and it
5691 does not reside in the SKE library. The function checks the version
5692 string remote end sent.
5694 * Added back pointers (to opaque context and to SilcSocketConnection)
5695 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5697 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5698 duplicate packet context structure.
5700 * Changed `notify' client operation to send same arguments as client
5701 receives from server except for ID's. ID's are mapped to correct
5702 ID entry and that is returned. Also, if channel entry is not sent
5703 by server but the notify is for channel the channel entry is sent
5704 to application (otherwise application doesn't know that it is for
5705 channel (library gets it from packet's Destination ID)).
5707 * Added silc_client_remove_from_channels into client library to
5708 remove a client from all channels it has joined to. Used when
5709 received SIGNOFF notify from server. Added also new function
5710 silc_client_replace_from_channels to replace old ID entry with
5711 new ID entry on all channels. Used when received NICK_CHANGE
5714 * Fixed ID Cache list handling in silc_idlist_get_client in
5715 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5716 to get (or query) client by ID.
5718 * Updated TODO list.
5720 * Added connection authentication status message defined by the
5721 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5722 support for these into the code in client and server side.
5724 * Added generic function silc_client_send_command to send any command
5725 with variable argument list. Application should use this function
5726 to send commands if the command functions provided by the library
5727 does not suite for the application's user interface needs.
5729 * Added new `failure' client operation. Application is notified about
5730 received failure packet if client is executing a protocol. In this
5731 case the protocol's execution has failed.
5733 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5734 is required by the protocol.
5736 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5737 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5740 * Added status flag to SilcSKE object to indicate realtime status
5741 of the SKE protocol.
5743 * Application receives now exactly same command reply arguments as
5744 the library receives from server. However, if ID is received the
5745 corresponding ID entry is returned to the application (eg. Client
5746 ID is mapped to correct SilcClientEntry entry and that is returned).
5747 Changed command_reply client operation due to this change.
5749 * Changed all ID's in commands and in command replys as ID Payloads.
5750 Change affected both client and server side codes.
5752 All ID's sent in SILC network (with execption of ID's in SILC
5753 Packet header) are sent in ID Payload to support variable length
5756 * Server now notifies nick changes and notifies all clients on
5757 the channels about the new nickname (about the new Client ID,
5760 * Implemented CMODE command to change channel modes. Supports all
5761 channel modes defined by the protocol specs except ban and invite
5762 lists. (Also, private channel key mode is supported but support for
5763 setting private channel key in client is missing, thus, this mode
5764 has no effect on client side (except that server requires that the
5765 client uses private channel key and normal channel traffic does not
5768 Also, invite mode works per se, but INVITE command does not work
5769 yet correctly, so you can set channel as invite only channel but
5770 inviting clients to the channel does not work (it is yet to be
5771 thought what's the best way to do it).
5773 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5774 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5775 Implemented CUMODE command to change user's mode on the channel.
5776 Supports all modes defined by the protocol specs.
5778 * Added NAMES command reply to return users modes on the channel.
5780 * Removed unnecessary and slow ciphers from lib/silccrypt.
5782 * Set SO_KEEPALIVE option to connection sockets by default.
5784 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5786 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5787 redefined the Notify Payload into protocol specs.
5789 * Added silc_id_payload_parse_id to get ID directly from raw
5792 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5795 accept searching by Client ID as well.
5797 * Added support for LEAVE and SIGNOFF notify types in client library.
5799 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5800 to parse ID Payload from raw data.
5802 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Added flags parameter into silc_ske_assemble_security_properties
5805 function in lib/silcske/silcske.[ch].
5807 * Changed notify client operation to fit better for notify messages
5808 sent by server. The notify payload received from server is now
5809 passed to the application (after parsing it to SilcNotifyPayload).
5810 It is application's responsibility to retrieve the arguments
5811 from the payload and show the message the way it wants. The message
5812 sent by server is implementation specific.
5814 * Changed public keys to comply with the protocol specification.
5815 Old public keys are not supported anymore and are not compatible.
5817 * Removed nickname from Channel Payload as the latest draft removed
5818 it. The client must resolve the nickname from the NAMES command
5819 reply received when it joined the channel.
5821 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5823 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Fixed some errors in protocol specification drafts.
5827 * Created lib/silccore/silcnotify.c to implement Notify Payload
5828 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5829 generic payloads described by protocol specifications. The file
5830 includes implementations for ID Payload and Argument Payload.
5832 * Changed Command Payload implementation to use the new Argument
5833 Payload. Changed command_xxxx_payload to command_payload_xxxx
5834 to comply with SILC coding conventions.
5836 * Added suppport for Argument Payload handling in Notify Payload
5837 implementation as protocol requires it. Added the new support
5838 into server and client lib as well.
5840 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added support for multiple nicknames on same channel. [n] is
5843 added locally to the nickname if there are more than one same
5844 nicknames on the channel.
5846 * Server now sends all nicknames that matched WHOIS request.
5847 Client also shows the list received from server.
5849 * Added TOPIC command to client side. User can now set and show
5850 current topic on channel.
5852 * Added MOTD command to client and server. Also, server sends the
5853 motd when client connects to the server.
5855 * Changed version strings to comply ISO 8601.
5857 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Fixed protocol error handling in client library. It should now
5860 cope even if the SKE fails for some reason.
5862 * Made new protocol specification drafts for submitting to IETF.
5864 * Implemented TOPIC command to server in silcd/command.c.
5866 * Added two new notify types into lib/silccore/silcnotify.h:
5867 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5868 notify nickname change and topic setting/change on a channel.
5870 * API change of command_reply operation in client library. The
5871 application gets now the status type received from server as well.
5873 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5877 * Cras fixed and optimized the packet handling even further and
5878 it should work now. Minor change to the prototype of function
5879 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5881 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added new function into lib/silcutil/silcschedule.[ch]:
5884 silc_schedule_with_fd to select() a specified fd. The function
5885 returns after timeout expires or data arrives or goes. The
5886 function is used by packet routines to wait that all data is
5887 received from network.
5889 * Fixed data reading from network in lib/silccore/silcpacket.c.
5890 The code now assures that all data is read from the fd and then
5891 continues packet processing. This was a bug fix since the code
5892 used to drop some data in some circumstances.
5894 * Added new function into lib/silcclient/client.[ch]:
5895 silc_client_start_key_exchange to start key exchange after
5896 connection has been established to server. The code internally
5897 now uses this funtion but its main purpose was to provide it
5898 for applications that perform their own connecting. After
5899 application has created a connection it merely calls this
5900 function to start the key exchange between client and server.
5901 The library takes care of everything else after that.
5903 Updated also lib/silcclient/README to explain the usage of
5906 * Do not send to application information that connection has
5907 been established. Application gets notified it by connect
5910 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Applied cras's patch to add silc_schedule_one function. The
5913 function runs scheduler once and returns.
5915 * Fixed the scheduler after cras messed it up. The timeout
5916 handling works now as it's supposed to work.
5918 * Added into lib/silccore/ silcnotify.h to include notify
5919 message types support. Changed silc_server_send_notify*
5920 functions, in server.[ch], to support those new notify types.
5921 Added the support for the notify types into client library,
5922 as well. Added new notify client operation into ops.h in
5925 * Changed silc_server_packet_send_to_channel to send normal
5926 packets instead of just channel message packets. The function
5927 is now used to send the notify packets to channels. It is not
5928 used to send channel message packets anymore, as server never
5931 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5932 va_arg()s as it seems to require it nowadays. I guess, if SILC
5933 is compiled with older va_arg() the new code should work anyway.
5935 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Splitted core library. Core library (lib/silccore) includes
5938 now only SILC protocol specific core (and common) components.
5939 Created new utility library (lib/silcutil) that includes more
5940 generic purpose stuff. The stuff for util library was taken
5941 from the old core library. This was minor and easy split.
5943 * Created SILC Client Library (lib/silcclient) that includes
5944 implementation of the SILC client without user interface. This
5945 was major move from silc/ directory. The code has been changed
5946 so that it is transparent towards the user interface. The
5947 silc/ directory includes now the same user interface as before
5948 and it uses the new client library. Read lib/silcclient/README.
5949 Basicly, the client library performs everything else related
5950 to SILC except user interface handling. Also, configuration
5951 files are considered to be part of user interface and library
5952 does not handle them.
5954 This change also changed a lot of structures, function naming etc.
5955 Most important change was that SilcClientWindow object was
5956 renamed to SilcClientConnection in the client library. Created
5957 also new file lib/silcclient/ops.h. Also added new files
5958 silc/local_command.[ch] and silc/client_ops.[ch].
5960 All these changes were made to make it easier for user interface
5961 designers to create what ever user interface for the SILC client
5964 It is also expected that the server will be moved to lib
5965 directory as well and SILC Server Library will be created;
5966 sometimes in the future.
5968 * Removed Local commands from lib/silccore/silccommand.h as
5969 they are application specific and new client library does not
5970 handle any of those anymore.
5972 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5973 old client implementation in silc/.
5975 * Added support for callback functions in SILC_LOG_* macros.
5976 Application can now set its own callbacks that will be called
5977 instead of using the default functions that will always print
5978 the debug messages to stderr (or stdout). Also, debugging can
5979 now be disabled by setting silc_debug to FALSE and re-enabled by
5980 setting it to TRUE. Note, that logging will still work even
5981 if debugging is disabled.
5983 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5984 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5985 silc_log_reset_debug_callbacks.
5987 * To enable debugging in silc client one must give now -d
5988 option on command line.
5990 * Changed silc_schedule_init to automatically allocate task queues
5991 if they are not allocated before calling it.
5993 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Added GMP 3.1 into math library.
5997 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6000 a channel in SILC network. The packet is used by servers and
6001 routers to notify other routers that user has left a channel.
6002 This little feature was missing until now. Added the feature
6003 to protocol specification as well.
6005 Added functions: silc_server_send_remove_channel_user and
6006 silc_server_remove_channel_user into server.[ch].
6008 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6009 lib/silccore/silcpacket.h. However, they are not implemented
6012 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Fixed joining to a channel and sending channel messages
6015 between server and router. The channel message sending should
6016 now work inside a cell.
6018 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Fixed the private message sending between server and router.
6021 The private message sending should now work inside a cell.
6023 * Added silc_server_replace_id into server.[ch] to replace
6024 existing ID in the SILC network.
6026 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6027 and silc_idlist_replace_server_id into idlist.[ch] in server.
6029 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Fixed the server to server connections. Server can again now
6032 connect to router. Router to router connections probably does
6035 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Added dynamic protocol registering support. Now protocols can
6038 registered and unregistered on the fly. Patch by cras.
6040 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Added lib/contrib directory to hold routines that some platforms
6043 don't have but are needed by SILC.
6045 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6046 into lin/contrib to provide getopt() and getopt_long() for
6047 those who don't have it.
6049 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Added AWAY command to client. When away message is set and
6052 client receives a private message packet the client automatically
6053 replies to the sender with the away message.
6055 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6056 bug seemed to be the cause of recent problems when compiling
6059 * Added version detection support to SKE protocol specification
6060 and added the new changes to the SKE implementation as well.
6061 There were other minor changes in the SKE protocol as well.
6063 Many changes in lib/silcske/silcske.[ch] and in
6064 lib/silcske/payload.[ch].
6066 * Added ^U functionality, clear input line. Patch from cras.
6068 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Mainly small bugfixes on core library. Fixed some debugging
6071 logging and buffer overflow in silclog.c.
6073 * Updated config.sub and config.guess on the distribution tree.
6075 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Added command lagging support in server. Client may execute
6078 commands now only once in two seconds.
6080 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Optimized packet reception. MAC computation and checking is now
6083 also more optimized. A lot previously duplicated code is now
6084 used as generic by both client and server.
6086 * Fixed key pair generation in clientutil.c
6088 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Added into lib/silccore/silcbufutil.[ch] new function;
6091 silc_buffer_realloc.
6093 * Moved generic packet sending/encryption functions to
6094 lib/silccore/silcpacket.[ch] from client and server. Some
6095 rewriting of the functions.
6097 * Moved all generic packet reception/decryption functions to
6098 lib/silccore/silcpacket.[ch] from client and server. The
6099 packet processing is now much cleaner in both client and server.
6100 These were major changes in both client and server.
6102 * Created many common functions in server to do packet sending.
6103 Previously code were duplicated a lot, this has been removed
6106 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6108 * Rewrote major parts of the ID cache system. Don't know
6109 whether it is better now or not but at least the API is more
6112 * Major rewrite on ID cache stuff on client because of the ID
6113 cache API changes. Added idlist.c to client.
6115 * Also major rewrite on ID cache stuff on server as well.
6116 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6117 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6118 in hand, instead they are all put into the ID cache system now.
6119 All server_idlist_* routines uses ID cache now instead of
6120 traversing its own lists (those lists does not exist anymore).
6121 SilcIDList though still exists. Also, SilcXXXEntry's are
6124 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Finally made the SKE implementation compliant to the protocol
6127 specification. All mp integers are now binary encoded as
6128 opposed being HEX encoded.
6130 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6133 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6134 functions: silc_[encode/decode]_pem. Also added function
6135 silc_encode_pem_file to PEM encode with newlines ('\n') for
6138 * SILC public keys are now encoded either PEM or binary. Same
6139 option is for private keys as well. By default private keys
6140 are binary encoded and public keys PEM encoded. Silly HEX
6141 encoding were removed.
6143 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6144 function to create fingerprints.
6146 * Fixed a bug in SHA1; does not change the original data anymore.
6148 * Partly implemented INFO command on client and server side.
6149 Fixed CLEAR command. Changes to SERVER command; show current
6150 server(s) when giving command without arguments. Added
6151 VERSION command to client.
6153 * Added check to server that unregistered connections cannot
6154 execute commands (unless it is specificly allowed).
6156 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Fixed screen refresh.
6160 * Fixed channel joining bug from client. On some circumstances
6161 client tried to join to a channel it had already joined.
6163 * Added public key verification process into client's protocol.c.
6164 The client now verifies the public key from user and saves
6165 it into ~./silc/serverkeys/ directory.
6167 Added into: clientutil.[ch]: silc_client_verify_server_key.
6169 * Changed SKE protocol's silc_ske_initiator_finish function
6170 to accept callback function that verifies the received public
6171 key. Removed old silc_ske_verify_public_key function.
6173 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6176 silc_pkcs_private_key[_data]_set.
6178 * Made the password and public authentication more cleaner in
6179 server's protocol.c.
6181 * Removed historic and obsolete protocol `channel_auth' from
6182 both client and server.
6184 * Removed wrong way of sending command status messages from
6185 server to client in server's command.c. The old way violated
6186 protocol specification.
6188 Changes to silccore/silccommand.[ch]: removed
6189 silc_command_encode_status_payload -> not needed anymore,
6190 changed silc_command_encode_payload_va to accept extra
6191 argument on variable argument list. The argument type must
6192 now be provided to the function. Also, added new function:
6193 silc_command_encode_reply_payload_va which is same as
6194 normal command_encode_payload_va except command status type
6195 is provided as extra argument.
6197 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Added ~./silc directory handling. The directory includes the
6200 public and private keys for the client.
6202 Added silc_client_check_silc_dir, silc_client_create_identifier
6203 and silc_client_load_keys.
6205 * Implemented SILC protocol compliant public key. Added public
6206 and private key saving to and loading from files.
6208 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6209 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6210 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6211 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6212 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6214 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6215 silc_pkcs_load_[public/private]_key.
6217 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * Added silc_server_get_route (route.[ch]) to get connection
6220 data for the fastest route for given ID.
6222 * Implemented INVITE command on client and server. The command
6223 were re-defined in the SILC Protocol Specification and the
6224 implementation now complies with the specification.
6226 * Implemented PING command on client and server.
6228 * Implemented NAMES command on client and server. The server side
6229 supports currently only normal server not router server yet.
6230 Some changes to NAMES definition in SILC protocol specification.
6232 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * Implemented LEAVE command on client and server.
6236 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6237 again. This change was made to the protocol as well. Server
6238 should not violate the protocol specification anymore.
6240 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6243 was tested. SOCKS4 was not but should work anyway.
