1 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3 * Added silc_net_gethostby[addr/name] into the
4 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
5 routines. Added silc_net_is_ip[4/6]. Affected file is
6 lib/silcutil/unix/silcunixnet.c. All routines that take
7 address as argument now supports both IPv4 and IPv6 addresses.
9 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
11 * Fixed LIST command reply sending in server. Affected file
14 * Server now sends the kicker's client ID in the KICK notify
15 to the kicked client. Affected file silcd/command.c.
17 * The client library now parses the kickers client ID and
18 UI displays it. Affected files lib/silcclient/client_notify.c
19 and irssi/src/silc/core/silc-channels.c, module-formats.c.
21 * Made all payload parsing function prototypes consistent.
22 They all take now const unsigned char * and uint32 pair as
23 the payload data instead of SilcBuffer. Changes all around
24 the source tree. Other unsigned char* -> const unsigned char*
25 changes around the tree as well.
27 * Optimized SFTP client and server packet sending not to
28 allocate new buffer for each packet but to recycle the
29 first allocated buffer. Affected files are
30 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
32 * Optimized the SFTP client to use SilcList instead of
33 SilcDList for requests, because it is faster. Affected file
34 is lib/silcsftp/sftp_client.c.
36 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
37 into lib/silccore/silcid.[ch].
39 Renamed silcpayload.[ch] into silcargument.[ch].
41 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
43 * If client entry is deleted with active key agreement
44 session, abort the session.
46 The silc_client_abort_key_agreement now calls the completion
47 callback with new SILC_KEY_AGREEMENT_ABORTED status.
49 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
52 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
54 * Don't use __restrict in older GCC's. Affected file is
55 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
57 * silc_net_localhost now attempts to reverse lookup the
58 IP/hostname. Affected file lib/silcutil/silcnet.c.
60 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
61 command. It can be used to gain founder privileges at
62 the same time when joining the channel.
64 Defined that the SILC_NOTIFY_TYPE_KICKED send the
65 kicker's client ID as well. Updated protocol specs.
67 Defined that the server must send SILC_COMMAND_IDENTIFY
68 command reply with error status to client who sent
69 private message with invalid client ID.
71 Updated the protocol specification.
73 * Added silc_server_send_command_reply to send any
74 command reply. Affected file silcd/packet_send.[ch].
76 * Added silc_id_payload_encode_data to encode ID payload
77 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
79 * The server now send IDENTIFY command reply with error
80 status if client ID in private message is invalid. Affected
81 file silcd/packet_receive.c.
83 * Save the server key file with server's IP address in
84 the filename instead of hostname. The affected file is
85 irssi/src/silc/core/client_ops.c.
87 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
89 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
92 * Added libtool support for compiling shared objects in
93 lib/silcsim. Affected file configure.in.pre and
94 lib/silcsim/Makefile.am. Original patch by cras.
96 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
98 * Pid file configuration, and server's config file fixes
99 patch by toma. Updated CREDITS file.
101 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Fixed silc_client_channel_message to not try to decrypt
104 the message twice if it resolved the destination client
105 information. This could cause of dropping one channel
106 message. Affected file lib/silcclient/client_channel.c.
108 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
110 * Added silc_client_run_one into lib/silcclient/silcapi.h and
111 lib/silcclient/client.c. This function is used when the SILC
112 Client is run under some other scheduler, or event loop or
113 main loop. On GUI applications, for example this may be
114 desired to used to run the client under the GUI application's
115 main loop. Typically the GUI application would register an
116 idle task that calls this function multiple times in a second
117 to quickly process the SILC specific data.
119 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
121 * Fixed silc_server_drop() for dropping the supplementary
122 groups as well, this could cause a security hole on some
125 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
127 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

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

571 * Added silc_net_localip to return local host's IP address.
572 Affected file lib/silcutil/silcnet.[ch].
574 * If key exchange or rekey protocol is active for a connection
575 parse all packets syncronously since there might be packets
576 in packet queue that we are not able to process without first
577 processing packets before them. Affected file silcd/server,
578 lib/silcclient/client.c.
580 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
581 whether library should continue processing the packet.
582 Affected file lib/silccore/silcpacket.h.

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

655 * Call the silc_server_udpate_servers_by_server in the
656 primary router that comes back online in the backup resuming
657 protocol. Otherwise it routes packets wrong. Affected file
658 silcd/server_util.[ch], silcd/server_backup.c.
660 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
663 lib/silcutil/silcbuffmt.[ch].
665 * Redefined the SILC packet header to include the padding
666 length. Affected file lib/silccore/silcpacket.[ch].
668 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
669 length for maximum padding up to 128 bytes). Affected
670 file lib/silccore/silcpacket.h.
672 * Removed all backwards support for old 0.5.x MAC thingies.
673 The SILC packet header change makes it impossible to be
674 backwards compatible.
676 * Send the ENDING packet with timeout in the backup resuming
677 protocol. This is to assure that all routers has connected
678 to the primary router. Affected file silcd/server_backup.c.
680 * Changed the RNG to take the first IV from random data. It
681 used to take it from zero actually. Changed the RNG also
682 to use /dev/urandom during session. /dev/random is used
683 in initialization. Affected file lib/silccrypt/silcrng.[ch].
685 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Changed the SILC packet header to have the first two bytes
688 (the packet length) encrypted. Affected files aroung the
689 code tree, lib/silccore/silcpacket.[ch]. Removed the
690 SilcPacketCheckDecrypt callback. It is not needed anymore
691 since the silc_packet_receive_process will determine now
692 whether the packet is normal or special.
694 * Implemented the unidirectional MAC keys. Affected files
695 lib/silcske/silcske.c, silcd/protocol.c and
696 lib/silcclient/protocol.c.
698 * Implemented the packet sequence number to the MAC computation.
699 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
700 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
701 lib/silcclient/protocol.c.
703 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
705 * Allow backup router to announce servers. All servers
706 announced by backup router are added to the global list
707 automatically. Update hte server's socket to our primary
708 router also when backup router announces a server.
709 Affected file silcd/packet_receive.c.
711 * Do not update the client->router in the function
712 silc_server_udpate_clients_by_server if the client is on
713 global list. We might fail to find any specific server
714 for locally connected clients and local cell clients. They
715 should still use the `from' and not `to' as client->router.
716 This fixes backup router resuming protocol. Affected file
719 * Decrease channel statistics count only if the channel
720 deletion worked. Affected files are silcd/server.c and
723 * Added silc_server_update_servers_by_server to update origin
724 of all server entries. Used during backup router protocol.
725 Affected files silcd/server_util.[ch], silcd/server.c. and
726 silcd/backup_router.c.
728 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
729 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
730 silc_hmac_get_hash and silc_hmac_get_name. Affected file
731 lib/silccrypt/silchmac.c.
733 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Assure that router cannot reroute the same channel message
736 to the sender. Affected file silcd/packet_receive.c.
738 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
740 * Made better checks that the channel message is not sent
741 to the router it came from. Affected file is
742 silcd/packet_send.c. Fixed memory leak too.
744 * Announce informations for incoming router connection, but
745 only after checking if it is replaced by backup router.
746 Affected file silcd/packet_receive.c.
748 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
750 * Fixed the backup resuming protocol to work in multiple
751 router environment. Affected file silcd/server_backup.c.
753 * Route packet only to one router in the function
754 silc_server_packet_send_to_channel. Affected file is
757 * Fixed silc_server_send_notify_dest to set the broadcast
758 flag. Fixed the silc_server_send_notify_topic to actually
759 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
760 Affected file silcd/packet_send.c.
762 * Changed the SFTP Filesystem interface. Changed the
763 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
764 the filesystem operation function. The SilcSFTPFilesystem
765 is now a context that is allocated by all filesystem allocation
766 functions and it already includes the operations structure
767 and filesystem specific context. It is given as argument
768 now to the silc_sftp_server_start. This made the interface
769 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
770 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
772 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Changed the backup router adding and getting interfaces
775 in the server. The router that will be replaced by the
776 specified backup router is now sent as argument. Affected
777 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
780 * Added silc_net_addr2bin_ne to return the binary form of
781 the IP address in network byte order. Affected files
782 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
784 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
786 * Check for existing server ID in silc_server_new_server
787 and in silc_server_connect_to_router_final and remove the
788 old entry if it exists. Affected file silcd/packet_receive.c,
791 * Send the channel message always to only one router, either
792 in upstream or downstream. Affected file is
795 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

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

826 send any data. Affected file silcd/packet_send.c.
828 * Assure that if outgoing data buffer is pending do not force
829 send any data. Affected file lib/silcclient/client.c.
831 * Implemented the backup router support when the primary router
832 goes down. The servers and routers can now use the backup
833 router as new primary router without loosing connectivity.
835 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
838 in the server to indicate disabled entry. All data read
839 from the connection will be ignored and no data is sent
840 for entry that is disabled. Affected files are
841 silcd/idlist.h, silcd/server.c.
843 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Created SFTP client and server test programs in the
846 lib/silcsftp/tests directory.
848 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Implemented memory filesystem (virtual filesystem) for
851 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
854 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Implemented the SFTP (SSH File Transfer Protocol) to the
857 lib/silcsftp. It includes SFTP client and SFTP server
860 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
862 * Moved lib/silccore/silcprotocol.[ch] to the
863 lib/silcutil library.
865 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
866 take variable argument list pointer as argument. Affected
867 file lib/silcutil/silcbuffmt.[ch].
869 * Added silc_buffer_set function that is used to set data
870 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
871 Affected file lib/silcutil/silcbuffer.h.
873 * Changed various routines in the core library to use the new
874 silc_buffer_set instead of allocating new buffer only for
877 * Added 64-bit value formatting and unformatting support to the
878 silc_buffer_[un]format routines. Affected file is
879 lib/silcutil/silcbuffmt.[ch].
881 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
882 to includes/bitmove.h.
884 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
886 * Fixed channel user mode saving in client library. Affected
887 file lib/silcclient/command[_reply].c.
889 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Defined the file transfer to the SILC Protocol. Added
892 new packet type SILC_PACKET_FTP and defined File Transfer
893 Payload. The mandatory file transfer protocol is SFTP
894 (SSH File Transfer Protocol). Affected file in addition
895 of the internet draft is lib/silccore/silcpacket.h.
897 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
898 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
899 is used as part of backup router protocol when the primary
900 router of the cell is back online and wishes to resume
901 the position as primary router.
903 * Redefined the MAC generation keys in the protocol. The
904 same key is not used anymore in both direction. Both
905 direction will now use different keys for sending and
906 receiving. This fixes a potential security flaw. This
907 change causes incompatibilities in the protocol.
909 * Redefined also the MAC computation from the packet.
910 An packet sequence number is now added to the MAC
911 computation. This prevents possible replay attacks against
912 the protocol. This change too causes incompatibilities
915 Added `sequence' field to the SilcPacketContext to hold
916 the current sequence number for the packet.
918 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Added `created' field to the SilcIDListData in the file
921 silcd/idlist.h to indicate the time when the entry was
924 * Added `created' field to the SilcChannelEntry too. Affected
927 * Added `creation_time' aguments to all the announcement functions
928 in the server. If it is provided then only the entries that
929 was created after the provided time frame are actually
930 announced. Affected file silcd/server.[ch].
932 * The protocol says that the Channel ID's IP address must be
933 based on the router's IP address. Added check for this in
934 the silc_server_new_channel when processing incoming New Channel
935 Payload. Affected file silcd/packet_receive.c.
937 * Print out the correct version with --version in SILC client.
938 Affected file irssi/src/silc/core/silc-core.c.
940 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

943 entry always, not just when the command is coming from client.
944 Affected file silcd/command.c.
946 * Added new function silc_server_packet_queue_purge to purge the
947 outgoing data queue to the network. After the function returns
948 it is guaranteed that the outgoing packet queue is empty.
949 Affected file silcd/packet_send.[ch].
951 * Purge the outgoing packet queue in the rekey protocol's final
952 callback to assure that all rekey packets go to the network
953 before quitting the protocol. Affected file silcd/server.c.
955 * Added silc_client_packet_queue_parse as similar function as
956 in server to the client library. The affected file is
957 lib/silcclient/client.c.
959 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Splitted silcd/server.c and created silcd/server_util.[ch]
962 for utility functions.
964 * Added new socket flag SILC_SF_DISABLED to indicate that the
965 connection is open but nothing can be sent to or received from
966 the connection. Affected file lib/silcutil/silsockconn.[ch].
967 The checking for disabled socket is checked in the low level
968 silc_socket_write and silc_socket_read functions.
970 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
972 * Allow only nicknames and channel names that fits into the
973 7-bit unsigned char ASCII set. Affected file silcd/command.c.
975 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
977 * When processing JOIN command reply in server check that if
978 the channel exists in our global list we'll move it the local
979 list. Affected file silcd/command_reply.c.
981 * Fixed the check whether client is joined on the channel already
982 in JOIN command. Affected file lib/silcclient/command.c.
984 * Fixed the JOIN command reply to check whether the channel
985 already exists. Affected file lib/silcclient/command_reply.c.
987 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Added silc_ske_status_string to map the SKE error numbers
990 to readable strings. The affected files are
991 lib/silcske/silcske[_status].[ch].
993 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
995 * Do not show the private channels on the WHOIS channel list
996 as it is not allowed by the protocol. The affected file is
999 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Assure that the packet length digged from the actual packet
1002 is something sensible in the silc_packet_decrypt_rest_special
1003 in lib/silccrypt/silcpacket.c.
1005 * Free and NULL the allocated pointer in silc_hmac_alloc if
1006 the HMAC allocation fails. The affected file is
1007 lib/silccrypt/silchmac.c.
1009 * Print the selected security properties to the log files in
1010 the server. Affected file silcd/protocol.c.
1012 * Add SKE's reference counter even if calling the completion
1013 callback manually. Otherwise it goes negative, although it
1014 does not cause any problems. The affected file is
1015 lib/silcske/silcske.c.
1017 * Remove the client entry with short timeout after giving the
1018 KILL command. Affected file lib/silcclient/command.c.
1020 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1021 case all found clients are already disconnected (WHOWAS would
1022 found them) in the server. Affected file silcd/command.c.
1024 * Update the last_receive (time of last data received) to be
1025 updated only when received private or channel message so that
1026 the idle time showed in WHOIS makes more sense.
1028 * Added boolean field `valid' in to the SilcClientEntry in the
1029 client library to indicate whether the entry is valid or not.
1030 This fixes the nickname change bug on channel when changing
1031 the nickname to be same than the old (like nick to Nick) the
1032 nickname formatter doesn't set the new nick anymore to Nick@host.
1033 Affected file lib/silcclient/idlist.[ch].
1035 * Now actually fixed the nickname changing on disconnection.
1036 Added new function silc_change_nick to the Irssi SILC Client.
1037 Affected file irssi/src/silc/core/client_ops.c,
1038 irssi/src/silc/core/silc-nicklist.[ch].
1040 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Check that the public key exists in the GETKEY command before
1043 trying to encode it. Affected file silcd/command.c.
1045 * Print some notifications on received public keys with GETKEY
1046 command in the Irssi SILC Client. Affected files are
1047 irssi/src/fe-common/silc/module-formats.[ch],
1048 irssi/src/silc/core/client_ops.c.
1050 * Use IDENTIFY command to resolve the server information in the
1051 GETKEY command instead of INFO command. Affected file
1052 lib/silcclient/command.c.
1054 * All command reply functions in the client library now calls
1055 the pending command reply callbacks even if an error has
1056 occurred. The server has done this a long time and now it was
1057 time to move the client library to this as well. Now all
1058 errors can be delivered back to the pending command reply
1059 callbacks if necessary. Affected files are
1060 lib/silcclient/command[_reply].[ch].
1062 * Change the nickname on disconnection back to the username
1063 because in reconnect the server will enforce it to it anyway.
1064 Affected file irssi/src/silc/core/silc-servers.c.
1066 * Fixed a config file parsing bug in the Irssi SILC client.
1067 Affected file irssi/src/silc/core/clientconfig.c.
1069 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * When printing the channel mode on JOIN, verify that the
1072 channel key and channel's HMAC are valid. Affected file
1073 irssi/src/silc/core/client_ops.c.
1075 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1078 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1079 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1081 * Removed channel key rekey task deleting from the function
1082 silc_server_save_channel_key. Affected file silcd/server.c.
1083 Added explicit timeout task context instead that is used to
1084 delete the task if we are registering a new task before the
1085 new task has elapsed.
1087 * When channel key rekey occurs the client library now saves
1088 the old channel key for a short period of time (10 seconds) and
1089 is able to use it in case some is still sending channel
1090 messages encrypted with the old key after the rekey. Affected
1091 file lib/silcclient/[idlist.h|client_channel.c].
1093 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Added check to the silc_server_new_id_real to not accept
1096 new ID if it is the sender's own ID. Affected file is
1097 silcd/packet_receive.c.
1099 * Assure that we do not announce ourself or the one we've
1100 sending our announcements when we're router and are announcing
1101 servers to our primary router. Affected file silcd/server.c.
1103 * Fixed silc_server_command_identify_check_client to assemble
1104 correct WHOIS packet. It send corrupted WHOIS packet and
1105 caused problem with router to router connections. Affected
1106 file silcd/command.c.
1108 Fixed also silc_server_command_whois_check the same way
1109 as for the IDENTIFY command.
1111 * Added new SilcIDListStatus to the server in the SilcIDListData
1112 structure. The status now includes the current status of
1113 the entry (like registered, resolved etc.). Affected file
1114 silcd/idlist.[ch]. Defined a bunch of different status types
1115 as well. This replaced the old boolean registered field as well.
1117 Added resolve_cmd_ident field to the SilcClientEntry structure
1118 too so that if the entry is for example being resolved so
1119 another command may attach to the same pending command reply
1120 without requiring to resolve the same entry again. This concept
1121 should optimize the WHOIS and the IDENTIFY resolving under
1122 heavy load by taking away unnecessary resolving for entries
1123 that are being resolved already.
1125 Added support for adding multiple pending commands for one
1126 command idenfier. Affected file silcd/command[_reply].[ch].
1128 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1129 before deleting the data. Otherwise the hash table will have
1130 freed data in comparison functions. Affected file is
1131 silcd/command_reply.c.
1133 * Fixed silc_idlist_replace_client_id to add the new entry to
1134 the cache with NULL nickname. Otherwise there will be invalid
1135 memory as the nickname after the nickname is freed. Affected
1136 file silcd/packet_receive.c.
1138 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1139 saved into wrong slots because the previous number of entries
1140 was not taken into account. Affected file silcd/idlist.c.
1141 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1143 * If we are router and we receive JOIN notify to a channel that
1144 does not have any users then notified client is marked as the
1145 channel founder, as it is it. The affected file is
1146 silcd/packet_receive.c
1148 * Added to the extended hash table API's table_del_*ext functions
1149 the destructor as argument too, so that the caller can decide
1150 which destructor to use or whether to use destructor at all.
1151 Affected file lib/silcutil/silchashtable.[ch].
1153 * Fixed ID Cache purging. It actually deleted the entries from
1154 the hash table after the data was freed. The hash table ended
1155 up comparing freed memory. The affected file is
1156 lib/silccore/silcidcache.c.
1158 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1160 * Fixed Irssi SILC client's KILL command's HELP syntax.
1162 * The USERS command now resolves the detailed user information
1163 if the userinfo field is missing. Affected file is
1164 lib/silcclient/command_reply.c.
1166 * Do not print error in silc_file_read if the read file does
1167 not exist. Just silently return NULL. Affected file is
1168 lib/silcutil/silcutil.c.
1170 * Fixed the silc_log_output to not wine about NULL filename
1171 and to not create some bogus " " filename. Affected file is
1172 lib/silcutil/silclog.c.
1174 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1176 * Fixed various printing bugs on the user interface in the
1177 Irssi SILC Client. Minor changes that were forgotten from
1180 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Fixed the configure.in.pre and the compilation and distribution
1183 environment to support the new autoconf 2.52. That version is
1184 now required to compile the CVS trunk.
1186 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1189 to generally parse user@fqdn format strings. Affected file
1190 lib/silcutil/silcutil.c.
1192 * Added nickname_format and nickname_force_format fields to the
1193 SilcClientParams structure. The first one defines the format
1194 for the nicknames that the library will enforce if the receives
1195 multiple same nicknames. The second one is boolean value and
1196 can be used to force the library to always enforce the format
1197 to the nicknames regardles whether there are multiple nicknames
1198 or not. This configurable formatting was employed to flexibly
1199 support accessing multiple nicknames from the user interface.
1200 The userinterface can now set the nicknames to what ever format
1201 they prefer. Affected file lib/silcclient/silcapi.h.
1203 Added function silc_client_nickname_format to the file
1204 lib/silcclient/idlist.c. It performs the nickname formatting.
1206 Added new field `hostname´ to the SilcClientEntry context.
1207 It holds the hostname of the client. Affected file is
1208 lib/silcclient/idlist.h.
1210 * Irssi SILC Client sets the nicknames in nick@hostn format.
1211 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1212 irssi/src/silc/core/silc-core.c.
1214 The WHOIS printing now also shows both the real nickname and
1215 the formatted nickname so that user knows how to access the
1216 user if there are multiple same nicknames cached. Affected
1217 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1218 printing formatting too to take the hostname now as a separate
1219 argument. The Affected file is
1220 irssi/src/fe-common/silc/modules-formats.[ch].
1222 * Changed the silc_client_get_clients_local to accept the formatted
1223 nickname as argument. It accepts the real nickname too but the
1224 formatted nickname can be used to find the true entry from
1225 multiple entries. Affected file lib/silcclient/silcapi.h and
1226 lib/silcclient/idlist.c.
1228 * Added nickname_format_parse field to the SilcClientParams.
1229 It is a callback function provided by the application to parse
1230 the nickname out of the formatted nickname string. The library
1231 calls it to get the nickname from the formatted string. Since
1232 the application generally knows better the format of the nickname
1233 string it parses it instead of the library, even though library
1234 encodes the formatted string. If the callback function is not
1235 provided then the library will use the string as is. The
1236 affected file is lib/silcclient/silcapi.h.
1238 * All the nickname strings passed to the client library in
1239 commands are now expected to be formatted nickname strings.
1240 If the command does not support the formatted nickname string
1241 it will assume that the sent string is the actual nickname.
1242 Affected file lib/silcclient/command.c.
1244 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Added public key authentication support to OPER and SILCOPER
1247 commands in the client library. Affected file is
1248 lib/silcclient/command.c.
1250 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Changed the get_auth_methdod client operation to be asynchronous.
1253 It can be async if the application resolves the authentication
1254 method from the server during the negotiation. Added new
1255 SilcGetAuthMeth completion callback that the application will
1256 call after resolving the authentication method.
1258 Added function silc_client_request_authentication_method that
1259 the application can use to resolve the authentication method
1260 from the server. Added also SilcConnectionAuthRequest callback
1261 that the library will call after the server has replied. The
1262 application can call this function if it does not know the
1263 current authentication method.
1265 Affected files are lib/silcclient/client.c and
1266 lib/silcclient/silcapi.h.
1268 * The Irssi SILC client now automatically resolves the authentication
1269 method incase any configuration information is not present (and
1270 currently there never is). The affected file is
1271 irssi/src/silc/core/client_ops.c.
1273 * Fixed public key authentication from the client library.
1274 Affected file lib/silcclient/protocol.c. Changed also the
1275 protocol specification about the public key authentication in
1276 the connection authentication protocol. The actual data to be
1277 signed is now computed with a hash function before signing.
1279 * Fixed the public key authentication from the server as well.
1280 Affected file silcd/protocol.c.
1282 * Removed the mlock()'s from the memory allocation routines.
1283 Affected file lib/silcutil/silcmemory.c. The ./configure does
1284 not check anymore for the mlock(). Affected file is
1287 * Fixed USERS command in server to allow the execution of the
1288 command for private and secret channels if the client sending
1289 the command is on the channel. Affected file silcd/command.c.
1291 * Fixed silc_client_get_clients_local to return the clients
1292 count correctly. It could return wrong value. Affected file
1293 lib/silcclient/idlist.c.
1295 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1298 types. The assembler optimizations seemed not to like 64-bit
1299 data types. The assmebler optimizations thus are now enabled
1300 also for BSD systems as opposed to only enable them for Linux.
1302 * Do not check for threads at all on BSD systems. Affected
1303 file configure.in.pre.
1305 * Removed -n and -h options from the Irssi SILC Client since
1306 they are not used in silc.
1308 * Fixed the prime generation to assure that the first digit
1309 of the generated random number is not zero since our conversion
1310 routines does not like number strings that starts with zero
1311 digit. If zero digit is seen the random number is regenerated.
1312 This caused some corrupted RSA keys when the zero first digit
1313 was met. Affected file lib/silcmath/silcprimegen.c.
1315 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Fixed WIN32 configuration in the ./configure script.
1318 Fixed to include xti.h on environments that has it.
1319 Patches by Carsten Ilchmann and andrew.
1321 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Changed the silc_id_create_client_id to be collision
1324 resistant. It is now assured that there cannot be created
1325 two same client ID's. I suspect that some weird bugs in
1326 the server were actually caused by duplicate Client IDs.
1327 Affected file silcd/serverid.[ch]. A router receiving
1328 new ID now also assures and informs the sending server
1329 if the ID caused collision.
1331 * Changed the silc_id_create_channel_id to also assure that
1332 there are no collisions.
1334 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Statement about ignoring the Mutual Authentication flag when
1337 performing rekey with PFS was a bit misleading. It is ignored
1338 if it was set in the initial negotiation, it cannot be even
1339 set in the rekey. Fixed in the ke-auth draft. Started the
1340 new versions of the protocol drafts in the doc/.
1342 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Fixed a bug in silc_client_command_identify_save when saving
1345 new channel information. The channel name was no duplicated
1346 and caused crash on exit. Affected file is
1347 lib/silcclient/command_reply.c.
1349 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Fixed the getkey command handling in the server. Send just
1352 empty OK reply to the sender if the key could not be fetched
1353 (but everything else was ok, like the key just was not available).
1354 Changed the public key parameter to optional in the protocol
1355 specs so that empty OK reply can be sent. Affected file
1358 Added a message to Irssi SILC client to tell to user if the
1359 server did not return a public key.
1361 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Fixed a channel key regeneration bug. It registered new
1364 timeout tasks exponentially until all system resources were
1365 used. Affected file silcd/server.c.
1367 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Added the SILC Document generator to the scripts/silcdoc.
1370 It can be used to generate the Toolkit Reference Manual out
1371 of the source tree. Internally it will also use the RoboDoc
1372 generator now imported in util/robodoc.
1374 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Added couple of return's in rekey protocol if error orccurred
1377 during the protocol. The execution must be terminated.
1378 Affected file silcd/protocol.c. Also, terminate the protocol
1379 always with timeout.
1381 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * The client's Client ID was created initally from the wrong
1384 nickname (it could have been in format nick@host) in the
1385 silc_server_new_client. Affected file silcd/packet_receive.c
1387 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * Added some SILC_LOG_ERROR's to various error conditions
1390 if client could not be added to ID cache. Affected files
1391 silcd/packet_receive.c and silcd/server.c.
1393 * When client's sock->user_data is freed, NULL also the
1394 client->router and client->connection pointers. Added check
1395 for these pointers being NULL to various places around the
1396 code. Affected file silcd/server.c.
1398 * Added client->data.registered == TRUE checks to various
1399 places around the code to assure that unregistered client's
1400 are not handled when it is not allowed. Affected file
1403 * Added `bool registered' fields to all
1404 silc_idlist_[server|client]_get_* routines to indicate whether
1405 the fetched client needs to be registered or not. Affected
1406 file silcd/idlist.[ch].
1408 * Add your own entry as registered to the ID cache in the
1409 server. Affected file server.c.
1411 * Fixed a bug in silc_server_new_server. The SilcServer was
1412 set as the new server's context instead of SilcServerEntry.
1413 This naturally caused some weird bugs.
1415 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Do not delete the channel rekey task when adding it
1418 for in silc_server_create_channel_key.
1420 * Changed the silc_server_create_channel_key to return
1421 TRUE or FALSE to indicate the success of the channel key
1424 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Fixed MSVC++ project files and added missing files to
1427 Makefiles under win32/.
1429 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * Do not add TCP_NODELAY flag if the operating system
1432 does not have it defined. Affected files are
1433 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1435 * Fixed buffer overflow from Irssi SILC Client. Affected
1436 file irssi/src/fe-common/core/themes.c.
1438 * Fixed double free in client library in the file
1439 lib/silcclient/client.c when disconnecting from server.
1441 * Applied double free patch from cras to Irssi SILC client.
1442 Affected files irssi/src/core/[modules/expandos].c
1444 * Fixed the disconnection handling to Irssi SILC Client.
1445 The application must call silc_client_close_connection
1446 in ops->connect client operation in case of failure of
1447 the connection. Affected file is
1448 irssi/src/silc/core/client_ops.c.
1450 * Do not set sock->protocol to NULL in the function
1451 silc_client_close_connection after executing the protocol's
1452 final callback since the sock might not be valid anymore.
1453 Affected file lib/silcclient/client.c.
1455 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Do not enable SILC_THREADS if the linking with libpthread
1458 did not happen. Affected file configure.in.pre.
1460 * Added notion to protocol specification that server must
1461 verify the sent authentication payload with CMODE when
1462 setting the channel founder key. Implemented it to the
1463 server. Affected file silcd/command.c.
1465 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Added _EXTRA_DIST SILC distribution variable to the
1468 distributions file. It is used to conditionally add extra
1469 files or directories to the specific distribution. Affected
1470 files ./prepare, Makefile.am.pre and distributions.
1472 Removed the `_' from the start of the distribution names.
1475 * Added README.WIN32 for instructions to compile the Toolkit
1478 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Fixed a double free in disconnection in the server. Affected
1481 file is silcd/server.c.
1483 * Fixed the lib/silcske/groups.c to work now also with GMP
1484 MP library. The string conversion did not work when using
1485 specific base and the base is indicated in the string as well.
1487 * Created win32/ directory which now includes MSVC++ specific
1488 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1489 It will appear only in the toolkit distribution
1491 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Changed the key material distribution function in case when
1494 the hash output is too short. The data is now concatenated
1495 a bit differently than it used to. Made the change to the
1496 SKE protocol specification.
1498 * Added better GMP detection to configure.in.pre. A patch
1501 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Fixed a minor bug in SKE that might cause some problem on
1504 some platforms. Affected file lib/silcske/silcske.c.
1506 * Added the cookie checking for initiator in the SKE. It checks
1507 that the responder returns the sent cookie unmodified. The
1508 affected file is lib/silcske/silcske.c. Added new SKE
1509 error type INVALID_COOKIE that can be sent during the
1510 negotiation. Fixed some memory leaks as well.
1512 * Added the "invalid cookie" error message to Irssi SILC client's
1515 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Added `task_max' field to the SilcClientParams to indicate
1518 the maximum tasks the scheduler can handle. If set to zero,
1519 default values are used. Affected file lib/silcclient/silcapi.h.
1521 * Fixed memory leaks in silc_client_close_connection. Affected
1522 file lib/silcclient/client.c.
1524 * Added silc_client_del_client_entry to client library to free
1525 all memory of given client entry. Affected file is
1526 lib/silcclient/idlist.[ch].
1528 * Added new functions silc_client_del_channel and
1529 silc_client_del_server to delete channel and server entries.
1530 Affected file lib/silcclient/[silcapi.h/idlist.c].
1532 * Removed silc_client_del_client_by_id from silcapi.h.
1534 * Fixed the INFO command to return the server's own info
1535 correctly when querying by Server ID. Affected file is
1538 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Removed the non-blocking settings in WIN32 code in the
1541 silc_sock_[read/write] and added SleepEx instead. Affected
1542 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1543 of input data is now checked with FIONREAD and ioctlsocket.
1545 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Call silc_schedule_task_del_by_context in the
1548 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1549 Affected file lib/silccore/silcprotocol.c.
1551 * Call silc_protocol_cancel for active protocols in the
1552 silc_server_close_connection if the funtion
1553 silc_server_free_sock_user_data has not been called.
1554 Affected file silcd/server.c.
1556 * Generic tasks cannot be deleted using the del_by_fd
1557 task deleting function since generic tasks does not match
1558 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1560 * Added a notion to SILCOPER help file that the SILCOPER works
1561 only on router server, not on normal server.
1563 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Added for WIN32 support for the new scheduler as well.
1566 Affected file lib/silcutil/win32/silcwin32schedule.c.
1568 * Fixed the SHA1 implementation to work on various platforms.
1570 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1573 API. It is part of the scheduler now. Everything else is
1574 as previously but some functions has changed their names.
1575 Checkout the lib/silcutil/silcschedule.h for the interface.
1576 Updated all applications to use the new interface. Affected
1577 files are lib/silcutil/silcschedule.[ch].
1579 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Found a bug in the SKE implementation. The HASH value,
1582 specified by the protocol, was not computed correctly. The
1583 public key of the responder was not added to the computation
1584 even though it is mandatory. Affected file lib/silcske/silcske.c.
1585 This unfortunately causes incompatibilities with older
1586 clients and servers.
1588 * Added WIN32 specific network init and uninit functions:
1589 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1590 the Winsock2. Affected file lib/silcutil/silcnet.h and
1591 lib/silcutil/win32/silcwin32net.c.
1593 * Set the socket always to nonblocking mode on WIN32 after
1594 reading data or writing data. Affected file is
1595 lib/silcutil/win32/silcwin32sockconn.c.
1597 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Fixed various compilation problems under WIN32. Affected
1600 files lib/silcutil/win32/silcwin32thread.c and
1601 lib/silcutil/win32/silcwin32schedule.c.
1603 * Removed all _internal.h #includes from public header
1604 files. Internal headers must never be included from
1607 Removed also the lib/silcske/payload_internal.h file.
1609 * All include files that may be needed (public and some others
1610 included by the public headers) by application developers are
1611 now copied to the ./includes directory. It does not copy any
1612 internal headers. Affected file Makefile.defines.pre and all
1613 Makefile.am's under lib/ and subdirs.
1615 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Do not change the ~/.silc directory's permissions automatically.
1618 Affected file irssi/src/silc/core/clientutil.c.
1620 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Do not cancel the protocol in silc_server_close_connection
1623 it might cause recursion. Now cancelled in the function
1624 silc_server_free_sock_user_data. Affected file silcd/server.c.
1626 * Fixed the silc_server_remove_clients_by_server to regenerate
1627 the channel keys correctly finally. Added also new function
1628 silc_server_remove_clients_channels to actually do it.
1629 Affected file silcd/server.c.
1631 * Fixed the silc_server_new_channel to not crash by giving
1632 wrong router to the new channel. Affected file is
1633 silcd/packet_receive.c.
1635 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1638 which is given as argument to the silc_client_alloc now.
1639 It can be used to configure the client and set various parameters
1640 that affect the function of the client.
1642 * The USERS command in server did not check whether the channel
1643 is private or secret. Affected file silcd/command.c.
1645 * Added new argument to the USERS command in protocol specification.
1646 The USERS command now can take the channel name as argument
1647 as well. Added support for this in client and server and
1648 updated the protocol specs.
1650 * Completed the GETKEY command in client. It can be now used
1651 to fetch also servers public key not only some clients.
1652 Affected files lib/silcclient/command[_reply].c.
1654 * Added silc_client_get_server to return server entry by the
1655 server name. Affected files lib/silcclient/silcapi.h and
1658 * Redefined the IDENTIFY command in protocol specification to be
1659 more generic. It now can be used to query information about
1660 any entity in the SILC Network, including clients, servers and
1661 channels. The query may be based either the entity's name
1662 or the ID. Added support for this in both client and server.
1664 Affected files silcd/command.c and lib/silcclient/command.c
1665 and command_reply.c.
1667 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1668 the _from_client and _from_server functions. Affected file
1671 * Added silc_client_get_channel_by_id_resolve to the file
1672 lib/silcclient/silcapi.h to resolve channel information by
1673 its ID. Added also silc_client_get_channel_by_id that
1674 does not resolve it from the server.
1676 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Added SilcServerEntry context into the client library
1679 to represent one server. The INFO command now allocates
1680 these to save the resolved server info. For now on the
1681 client library will also keep information about servers,
1682 connected and resolved with INFO.
1684 The INFO command now allocates the SilcServerEntry context
1685 and saves the server info there. The COMMAND_REPLY in
1686 the INFO now returns the parameters to application in
1687 same order as defined in the protocol specification.
1689 The entries are cached in the client->server_cache.
1691 * The INFO command is now issued after received the Client ID
1692 from the server. Affected file lib/silcclient/client.c.
1694 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1695 to the application as the mode changer might be server.
1696 It is guaranteed that NULL is not returned anymore to the
1697 application. Affected file lib/silcclient/client_notify.c.
1699 The ID Type is now also passed to the application so that
1700 it can check whether the returned entry is SilcClientEntry
1703 Added new function silc_client_get_server_by_id to return
1704 the server entry by ID. Affected files are the
1705 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1707 * Do not create the channel in the Irssi SILC Client when issuing
1708 the JOIN command but when received the sucessful JOIN command
1709 reply. Otherwise the channel might get created even though we
1710 could not join it. The Affected file is
1711 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1713 * Fixed a channel joining bug in router. The router must also
1714 check the channel modes, invite and ban lists etc. when serving
1715 the JOIN command sent by normal server. Affected file is
1716 silcd/command.c. The router now resolves the client's
1717 information from the server who sent the JOIN command if it
1718 does not know it, and processes the JOIN command only after
1721 * Changed the SilcCommandCb to take new argument; void *context2.
1722 Affected file lib/silccore/silccommand.h
1724 The second argument in the command callbacks in the server now
1725 includes the SilcServerCommandReplyContext if the command was
1726 called as pending command callback from the command reply.
1727 Otherwise it is NULL. When called as pending the status of the
1728 command reply will be checked and if it was erronous the
1729 error will be sent to the original sender of the command.
1730 This way the client always receives the error messages even
1731 though the server was actually the one who received the error
1732 when it resent the command to router, for example. Affected
1733 files silcd/command[_reply].[ch].
1735 * Fixed sending WHOWAS command's error message to client if
1736 the requested client could not be found. It was missing.
1739 * Changed the CMODE and CUMODE commands reply arguments in the
1740 protocol specification. The Channel ID is now sent in both
1741 of the commands to identify the channel. Implemented this
1742 new feature to the client and server. Affected files
1743 lib/silcclient/command_reply.c and silcd/command.c.
1745 * Made better checks for invite and ban lists in the JOIN
1746 command in server. Affected file silcd/command.c.
1748 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * The server now performs the incoming host IP/DNS lookup
1751 using the silc_socket_host_lookup and thus does not block
1752 the server anymore. Affected file silcd/server.c.
1754 * Completed the multi-thread support for SILC Scheduler in
1755 the lib/silcutil/silcschedule.c.
1757 * Fixed the configure.in.pre to detect the pthread correctly
1760 * Fixed a deadlock in silc_task_queue_wakeup in the file
1761 lib/silcutil/silctask.c.
1763 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Added new function silc_schedule_wakeup that is used in
1766 multi-threaded environment to wakeup the main thread's
1767 schduler. It needs to be used when a thread adds a new task
1768 or removes a task from task queues. After waking up, the
1769 scheduler will detect the task queue changes. If threads
1770 support is not compiled in this function has no effect.
1771 Implemented the wakeup mechanism to both Unix and WIN32
1772 systems. Affected files are lib/silcutil/silcschedule.[ch],
1773 lib/silcutil/unix/silcunixschedule.c and the
1774 lib/silcutil/win32/silcwin32schedule.c.
1776 * Added new function silc_task_queue_wakeup to wakeup the
1777 scheduler by the specified task queue. Affected file
1778 lib/silcutil/silctask.[ch].
1780 * The silc_socket_host_lookup_start now wakes up the scheduler
1781 after adding the timeout task. Affected file is
1782 lib/silcutil/silcsockconn.c.
1784 * The silc_socket_host_lookup is synchronous now if the threads
1785 support is not compiled in. However, the callback is still
1786 called asyncronously through the scheduler, anyway. Affected
1787 file lib/silcutil/silcsockconn.c.
1789 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Added new function silc_socket_host_lookup to perform
1792 asynchronous IP and FQDN lookups for the socket connection.
1793 Affected files lib/silcutil/silcsockconn.[ch].
1795 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1798 that may or may not compile the mutex support in.
1800 Changed the silc_mutex_alloc interface. It allocates the
1801 mutex now to the sent pointer and returns TRUE or FALSE.
1803 Affected file lib/silcutil/silcmutex.h.
1805 * Wrote the SILC Task Queue interface to support multi-threads.
1806 Affected file lib/silcutil/silctask.[ch].
1808 * Wrote the SILC Scheduler to support multi-threads. Affected
1809 file lib/silcutil/silcschedule.c.
1811 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1814 in lib/silcutil/win32/.
1816 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Defined SILC Mutex API and SILC Thread API and implemented
1819 them for Unix. Affected files are
1820 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1821 lib/silcutil/unix/silcunixmutex.c and
1822 lib/silcutil/unix/silcunixthread.c.
1824 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Fixed the silc_server_remove_clients_by_server's channel
1827 key re-generation. The hash table handling was incorrect
1828 and would not work with many channels. Affected file is
1831 * Fixed some memory leaks around the server code.
1833 * Rewrote the silc_server_get_users_on_channel to support IPv6
1834 based Client ID's. Affected file silcd/server.c.
1836 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1837 specification. However, a separate document must be written
1838 to define the detailed signing procedure and the payload
1839 associated with the flag. Defined the flag to the
1840 lib/silccore/silcchannel.h as well.
1842 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Changed the dynamic tables to static size tables in the
1845 lib/silccrypt/silchmac.c.
1847 * Removed GCC dependencies from the code. A patch by cras.
1849 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Do not show the error "Error receiving packet bla bla"
1852 in server if it really was not an error (-2 means that reading
1853 is pending). Affected file silcd/server.c.
1855 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Fixed a possible crash in silc_server_remove_clients_by_server
1858 in silcd/server.c. Fixed there also some memory leaks.
1860 * Fixed the silc_idlist_replace_client_id. It could replace
1861 wrong key in the hash table. Affected file silcd/idlist.c.
1863 * Do not check whether there are global users on the channel
1864 if the channel->global_users is FALSE. Affected functions
1865 silc_server_remove_from_one_channel and
1866 silc_server_remove_from_channels in silcd/server.c. Also,
1867 do not check if the removed client is local as we can be
1868 sure that global client was not removed from the channel
1869 and checking for global users is not needed.
1871 * The silc_server_remove_clients_by_server now re-generates
1872 the channel keys correctly for those channels that had
1873 clients removed from them. Affected file silcd/server.c.
1875 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1877 * Found the reason of random crashes in the server. We weren't
1878 ignoring the SIGPIPE signal (which can be sent in write())
1879 and it crashed the server. Affected file silcd/silcd.c.
1881 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Assure that sock->user_data is not NULL in the function
1884 silc_server_packet_send in silcd/packet_send.c.
1886 * Disconnect the remote connection if it could not be added
1887 to any ID lists in the server. The affected file is
1890 * Check in silc_server_packet_send[_real/dest] that the
1891 socket is not disconnecting and ignore the data if it is.
1892 Affected file silcd/packet_send.c.
1894 * Define inline to __inline on native WIN32 compilation.
1895 Affected file includes/silcwin32.h.
1897 * Added some explicit type casts for inline code since MSVC
1898 require them. Affected files lib/silcutil/silcbuffer.h,
1899 lib/trq/silcdlist.h and lib/trq/silclist.h.
1901 * Print warning in log files from now on if the packet
1902 decryption fails. Affected file silcd/server.c.
1904 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Changed the `say' client operation's interface to accept
1907 new `type' argument to indicate the type of the message sent
1908 by the library. The application may filter the library's
1909 messages according the type. The affected file is the
1910 lib/silcclient/silcapi.h.
1912 * Added two new functions to lib/silcclient/silcapi.h:
1913 silc_client_del_client and silc_client_del_client_by_id.
1914 Affected file lib/silcclient/idlist.c.
1916 * Moved the clientincludes.h from includes/ to silc/ and
1917 serverincludes.h from includes/ to silcd/.
1919 * The modes for the CMODE and CUMODE are now passed as
1920 uint32 for application with COMMAND_REPLY. The affected
1921 file is lib/silcclient/command_reply.c.
1923 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * /WHOIS without arguments shows client's own information.
1926 Affected file lib/silcclient/command.c.
1928 * Changed PING to not accept any arguments. The specs
1929 says that client can ping only the connected server so
1930 requiring an argument is not needed. Affected file is
1931 lib/silcclient/command.c.
1933 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Fixed a fatal bug in private message sending and reception
1936 encryption and decryption when using private message keys.
1937 The implementation was incorrect and did not follow the
1938 specification. It causd that some of the message were
1939 lost since it did not use the sending and receiving keys
1940 as the protocol suggests. This has been fixed and will cause
1941 incompatibilities with older clients when sending private
1942 message encrypted with private message keys. Affected files
1943 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1944 and various other in Irssi SILC Client.
1946 Added `responder' boolean argument to the functions
1947 silc_client_add_private_message_key[_ske] to indicate when
1948 the key is added as responder or initiator of the key
1951 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Removed the silc_ske_check_version function and created
1954 a SilcSKECheckVersion callback. Added also a function
1955 silc_ske_set_callbacks that is now used to set all SKE
1956 callbacks. The callback functions are not given to
1957 the SKE functions anymore, but this function is used to
1960 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1962 * Added `silc_version' argument to the silc_client_alloc
1963 to define the version of the application for the library.
1964 The library will use the version string to compare it
1965 against the remote host's (usually a server) version
1966 string. Affected file lib/silcclient/silcapi.h
1968 * Added the KE protocol context to Key Agreement context
1969 in client library so that we can abort the SKE if it
1970 is in process when we get timeout. Affected file is
1971 lib/silcclient/client_keyagr.c.
1973 * Do not resolve the client ID forever if it returns in the
1974 first time that such client does not exist. This was done
1975 for example with private message. Affected file is
1976 lib/silcclient/client_prvmsg.c.
1978 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Do not add regex.h for WIN32. The affected file
1981 includes/silcincludes.h.
1983 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1984 not work yet 100%. It generates the DLL's automatically
1985 when compiling with --with-win32 under cygwin.
1987 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * lib/contrib/regex.c is not compiled on WIN32.
1991 * Added silc_net_get_socket_opt function to the
1992 lib/silcutil/silcnet.h.
1994 * Added includes/silcwin32.h for WIN32 specific includes
1997 * Do not use ptime structure or any of the posix process
1998 functions on WIN32 in lib/silccrypt/silrng.c.
2000 * Added silc_gettimeofday to provide generic function
2001 for struct timeval on all platforms. Added the function
2002 to lib/silcutil/silcutil.h.
2004 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2007 library as they clearly belong there. As a plus side we
2008 can make the actual socket connection routines platform
2011 Added also new generic function silc_socket_read and
2012 silc_socket_write (that used to be silc_packet_[read/write].
2013 The implementation of these are platform specific.
2015 * Added WIN32 specific routines of silc_socket_[read/write]
2016 to lib/silcutil/win32/silcwin32sockconn.c.
2018 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Added preliminary support for native WIN32 compilation under
2021 cygwin (using the -mno-cygwin option for GCC) to the
2022 ./configure.in.pre. The --with-win32 now prepares the
2023 compilation for native WIN32.
2025 * Rewrote the SILC Scheduler interface in the file
2026 lib/silcutil/silcschedule.h. The scheduler is now context
2027 based and does not have anymore any global static scheduler.
2028 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2029 and created lib/silcutil/win32 directory for WIN32 based
2032 * Added Unix specific network routines to the
2033 lib/silcutil/unix/silcunixnet.c and the old
2034 lib/silcutil/silcnet.c includes now only generic routines.
2036 Added WIN32 specific network routines to the
2037 lib/silcutil/win32/silcwin32net.c.
2039 * Added Unix specific utility functions from the
2040 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2042 * Added WIN32 SILC Scheduler to the file
2043 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2046 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Do not handle JOIN notify in the server if the target client
2049 is not registered (idata->registered == FALSE). The affected
2050 file is silcd/packet_receive.c.
2052 * Update the nickrec->founder in event_cumode in the Irssi SILC
2053 client. Affected file irssi/src/silc/core/silc-channels.c.
2055 * Fixed the CUMODE_CHANGE notify handling in the server when
2056 server and router are announcing their clients on channels.
2057 Now the mode changes are saved and notified correctly. The
2058 affected file is /silcd/packet_receive.c.
2060 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2061 They really did not replace the cache entry in the ID Cache.
2062 Now they do that. Affected file silcd/idlist.c.
2064 * Fixed the KICK notify handling in the Irssi SILC client to
2065 update the channel records so that the kicked client does not
2066 appear to be on the channel. The affected file is
2067 irssi/src/silc/core/silc-channels.c.
2069 * Always update the conn->current_channel when executing command
2070 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2072 * Fixed the KILL notify handling in Irssi SILC client to remove
2073 the killed client on all channels.
2075 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Fixed the silc_parse_command_line to remove extra spaces
2078 from the start and end of the arguments. Affected file is
2079 lib/silcutil/silcutil.c.
2081 * Cancel and free any active protocol in the function
2082 silc_server_close_connection. Affected file silcd/server.c.
2084 * Cancel and free any active protocol in the function
2085 silc_client_close_connction. Affected file is
2086 lib/silcclient/client.c.
2088 * Do not execute the KILL command for clients that are in
2089 history (ie. they are not in the network). Affected file is
2092 * Fixed KILL notify handling, client does not crash anymore.
2093 Affected file irssi/src/silc/core/silc-channels.c.
2095 * Reduced the default packet buffer size from 2048 to 1024 in
2096 lib/silccore/silcpacket.c.
2098 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2099 counter to the SKE context that is incresed when the SKE library
2100 performs async operation outside the library. If the outside
2101 process frees the SKE context and FREED status will be set
2102 and the library will detect after the sync operation that the
2103 libary is freed. The affected files are
2104 lib/silcske/silcske[_status].[ch].
2106 * Resolve the client entry information in the function
2107 silc_client_channel_message to assure that NULL pointer is not
2108 passed as client entry to the application. */
2110 * Fixed the task timeout calculation to assure that there is
2111 never negative timeouts. The affected file is
2112 lib/silcutil/silcschedule.c.
2114 * Fixed the channel user mode notification sending in server.
2115 It was sent point-to-point to the router (or to server by router)
2116 but it needs to be destined to a channel. The routines now
2117 supports sending the channel user mode notifys to the channels
2118 when announcing clients and channels. Affected files are
2119 silcd/server.c and silcd/packet_receive.c.
2121 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2122 It did not actually replace the old channel entry in the cache.
2123 Affected file lib/silcclient/client_notify.c.
2125 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Fixed a possible crash in silc_packet_send_prepare. It now
2128 assures always that there is enough space in the buffer and
2129 at the tail area of the buffer (for MAC).
2131 Fixed the inbound buffer reallocation in silc_packet_read.
2132 It was old code and did not handle the reallocation correctly.
2135 The affected file is lib/silccore/silcpacket.c.
2137 * Fixed buffer overflow in silc_parse_nickname in the file
2138 lib/silcutil/silcutil.c.
2140 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * make install generates new server keys only if there is not
2145 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2148 Added check that if the NOREPLY is set then we will not send
2149 the away message. This avoids infinite loop of away messages
2150 if both clients are away. The affected file is
2151 lib/silcclient/client_prvmsg.c.
2153 * Fixed client crash if /NICK was given without arguments.
2154 Affected file lib/silcclient/command.c.
2156 * Server does not send the invite list in INVITE command back
2157 to the client if the list was not altered. Added this notion
2158 to the protocol spec as well. Affected file silcd/command.c.
2160 Fixed possible crash in INVITE command by checking the
2161 value of silc_server_get_client_route command.
2163 * Fixed the INVITE notify type handling. The arguments are now
2164 taken in correct order and client does not crash. The affected
2165 file is irssi/src/silc/core/silc-channels.c.
2167 Removed the "Inviting xxx to channel" message from the
2168 client library away and let the application handle it.
2169 Affected file lib/silcclient/command.c. Added that message
2170 to Irssi SILC client's message formats.
2172 * Fixed CMODE command crash in client. It now checks the
2173 amount of arguments correctly and does not crash. The affected
2174 file is lib/silcclient/command.c.
2176 * Do not create new channel automatically in silc_channels_join
2177 but check whether the channel by that name already exists.
2178 Affected file irssi/silc/core/silc-channels.c.
2180 * Do not send the SERVER_SIGNOFF to router if the disconnected
2181 entity was the router. Affected file silcd/server.c.
2183 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2184 SILC client as it was missing from there.
2186 Added the handling of the KICK notify to the Irssi SILC client
2187 as it was missing. Added "you have been kicked" message to
2188 Irssi SILC client's message modules formats.
2190 Added the handing of the KILL notify to the Irssi SILC client
2191 as it was missing. Added the kill message module formats
2194 The affected file is irssi/src/silc/core/silc-channels.c.
2196 * The router did not save the channel mode the server announced.
2197 Affected file silcd/packet_receive.c.
2199 * Fixed a possible crash in INFO command in server. If the
2200 server did not provide the server info it crashed. Affected
2201 file silcd/command.c.
2203 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Fixed the GETKEY command in the server to check also the
2206 global list. Otherwise the GETKEY would not work correctly
2207 in normal SILC server. Affected file silcd/command.c.
2209 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Fixed GETKEY crash, it crashed if the command did not succseed.
2213 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2216 is now real and not just an macro interface to GMP.
2218 Removed the entire GMP from the source tree and imported new
2219 NSS MPI library instead. Reason for removing GMP is that it is
2220 extremely large and compiles extremely slow. The NSS MPI
2221 is only a few files and compiles in less than 10 seconds.
2222 The speed is also about the same as GMP. The MPI is imported
2223 to lib/silcmath/mpi.
2225 If the system has GMP installed we will still use the GMP.
2226 If it is not then the NSS MPI will be compiled.
2228 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Merged a long nickname (127 characters long) crash bugfix from
2231 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2233 * Merged a freed memory reference bugfix from Irssi CVS tree.
2234 Affected file irssi/src/core/commands.c.
2236 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * Added the server's public key sving and verification to the
2239 server when performing the SKE. This was missing and the
2240 remote server's (or router's) public key was accepted without
2241 checking whether we have it previously or trust it at all.
2242 Affected file silcd/protocol.c.
2244 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Check in the silc_server_timeout_remote if protocol is active
2247 and make sure that the protocol's final callback is called so
2248 that all memory if freed. Affected file silcd/server.c.
2250 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2252 * silc_server_whois_send_reply crashed the server if the nickname
2253 was 127 characters long. Affected file silcd/command.c.
2255 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Added sanity check to the silc_server_new_client. If the hostname
2258 is provided inside username then check that the provided hostname
2259 really is the same as the resolved one. If the hostname was not
2260 resolved then check it from the public key. Affected file is
2261 silcd/packet_receive.c.
2263 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2264 if the server disconnected us and the connection is not valid
2265 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2267 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2268 the library to the lib/silcutil/silcutil.[ch].
2270 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2272 * Close log file after open. Affected file
2273 lib/silcutil/silclog.c.
2275 * Check whether sock == NULL in silc_client_send_packet and return
2276 if it is. Affected file lib/silcclient/silcclient.c.
2278 * Check rec->entry == NULL in the Irssi SILC Client before
2279 sending the channel message. Affecte file is
2280 irssi/src/silc/core/silc-servers.c.
2282 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Merged a splitted window bugfix from Irssi CVS tree. The
2285 affected file is irssi/src/fe-text/textbuffer-view.c.
2287 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2288 It did not print nickname.
2290 * Improved the distributions system a bit.
2292 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2295 irssi/src/fe-text/gui-window.c.
2297 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2298 to in-active server. The affected file is
2299 irssi/src/silc/core/client_ops.c.
2301 * Resolve the client in USERS command reply if the entry does
2302 not have username resolved. The affected file is
2303 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2304 command to WHOIS command to really resolve stuff. The USERS
2305 is not used any more in any critical section so WHOIS can
2306 be used even though it might be slower than IDENTIFY.
2308 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2311 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Changed the protocol API a bit more consistent in the
2314 lib/silccore/silcprotocol.[ch].
2316 * Changed the following headers to ROBODoc format:
2318 lib/silccore/silcpayload.h
2319 lib/silccore/silcprotocol.h
2320 lib/silccore/silcsockconn.h
2322 All core library headers are now formatted.
2324 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Fixed a bug in Irssi SILC client; do not show that you are
2327 server/router operator if you really are not. Affected file is
2328 irssi/src/silc/core/client_ops.c.
2330 * Renamed silc_command_free_payload to silc_command_payload_free.
2331 Affected file lib/silccore/silccommand.h
2333 * Added silcmath.h to include the prototoypes of various routines
2334 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2337 * Changed the following headers to ROBODoc format:
2339 lib/silccore/silcchannel.h
2340 lib/silccore/silccommand.h
2341 lib/silccore/silcid.h
2342 lib/silccore/silcidcache.h
2343 lib/silccore/silcmode.h
2344 lib/silccore/silcnotify.h
2345 lib/silccore/silcpacket.h
2346 lib/silcmath/silcmath.h
2348 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * Added checking to the server code not to start the server if
2351 ciphers and stuff are not configured properly. Affected files
2352 silcd/serverconfig.[h] and silcd/server.c.
2354 * Changed the layout of the header files of the public interfaces
2355 in the SILC libraries. The new layout supports ROBODoc
2356 documentation tool (and some others) so that it is easy to create
2357 a library reference manual. All the other headers and source
2358 code must still follow the CodingStyle document. Also source
2359 code must not include these ROBODoc stuffs, only the headers.
2360 Furthermore, all public interface headers must now be named
2361 by using `silc' prefix, example: silcapi.h, silccipher.h.
2362 Some files were renamed due to this. All the other headers
2363 must not be used as public interfaces. I will update the
2364 CodingStyle document later. Changed following headers, so far:
2366 lib/silcclient/silcapi.h
2367 lib/silccore/silcauth.h
2368 lib/silccore/silcprivate.h
2369 lib/silccrypt/silcdh.h
2371 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Removed silc_client_packet_send_flush from the client library
2376 as it is not needed. Affected file lib/silcclient/client.[ch].
2378 * Added printing of message of unresolved authentication method
2379 to the Irssi SILC client. Added it to the module formats.
2380 Removed the same message from the client library.
2382 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Added new distribution feature, DISTLABEL. Every distribution
2385 can define own preprocessor label that can be used in the
2386 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2387 file distributions, acconfig.h.pre and prepare.
2389 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Added Makefile.defines_int to include the actual definitions
2392 for Makefile.defines.in. Tested the new distribution system,
2393 created distributions and tested installation.
2395 * Added AWAY message printing to the Irssi SILC client. Added
2396 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2398 * Added SCONNECT command to call the SILC's CONNECT command.
2399 Cannot use CONNECT directly since Irssi uses that internally.
2400 Affected file irssi/src/silc/core/silc-servers.c.
2402 Added ACTION local command. It is same as ME command but takes
2403 the channel as mandatory argument.
2405 Rewrote some of the Irssi's help files to suite for SILC
2408 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Added Makefile.defines[.in] that should for now on be included
2411 in all Makefile.am file in the source tree. That file includes
2412 all common compilation definitions for SILC source tree.
2414 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Minor changes to the ./prepare script to change the package
2417 name according the distribution name to the configure.in.
2419 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Created new distribution system. Added file `distributions'
2422 that defines all the distributions that can be created out of
2423 the SILC source tree. The ./prepare script now reads that
2424 file to determine how to prepare the distributions. The
2425 first argument to the ./prepare is the name of the distribution
2426 and second is the version of the distribution. If given
2427 without arguments it creates the default (toolkit) distribution
2428 with the default version (defined in ./prepare).
2430 All Makefile.am files that are subject to the distributions
2431 are now named as Makefile.am.pre. These are ./Makefile.am
2432 and lib/Makefile.am. Others may be changed later.
2434 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Added invite list, ban list, some key management and connection
2437 error message printing to module formats in the Irssi SILC client.
2439 * Added new silc_client_set_away_message to set the away message
2440 that is back to the person who sent private message. The
2441 affected file lib/silcclient/silcapi.h and the
2442 lib/silcclient/client_prvmsg.c.
2444 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Fixed the private message sending in the Irssi SILC client,
2447 added local command KEY to the Irssi SILC client.
2449 Added key management and key agreement message formats to the
2450 irssi/src/fe-common/silc/module-formats.[ch].
2452 Added USERS (alias WHO) printing, server/router operator
2453 indication and LIST command printing to the module formats.
2455 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Fixed channel joining notify handling, cumode notify handling
2458 from Irssi SILC client.
2460 * Added SILC specific module-formats to the Irssi SILC client so
2461 that SILC specific message hilighting, colors etc is possible.
2462 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2464 Added channel mode, channel user mode, actions, notices,
2465 whois and whowas printing to the the module-formats.c.
2467 * Fixed a bug in channel deletion in the server. The channel
2468 is not left to the cache even if the channel founder auth mode
2469 is set when there are no users anymore on the channel. Affected
2470 file silcd/server.c.
2472 * The silc_net_localhost now resolves the entire hostname including
2473 the domain name. Affected file lib/silcutil/silcnet.c.
2475 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Changed the ask_passphrase client operation to be ascynchronous.
2478 It has now a completion callback and a context that the
2479 application must call after it has got the passphrase from
2480 the user. Affected files lib/silcclient/silcapi.h,
2481 lib/silcclient/protocol.c, lib/silcclient/command.c and
2484 Added SilcAskPassphrase callback that the application calls
2485 to deliver the passphrase to the library.
2487 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2488 The public key verification and especially a certificate
2489 verification is asynchronous procedure.
2491 Added new SILC_SKE_STATUS_PENDING status to indicate the
2492 request is pending and a callback will be called to finalize
2495 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2496 indicate that remote end did not send its public key (or
2497 certificate), even though we require it. Added check for this
2498 condition in the SKE. This was a security bug, now fixed.
2500 Defined new SilcSKEVerifyCbCompletion callback that is called
2501 when the verification process is completed.
2503 The affected files lib/silcske/silcske_status.h and
2504 lib/silcske/silcske.[ch].
2506 * Changed the verify_public_key client operation to be async
2507 as well. Defined SilcVerifyPublicKey callback that is used to
2508 indicate the success of the public key verification process.
2510 Changed the server and client to use the new async client
2513 * Changed the Irssi SILC client's internal scheduler to be called
2514 twice as many times as it used to be. As a result the client
2515 should be a bit faster now. Affected file is
2516 irssi/src/silc/core/silc-core.c.
2518 * Added support to Irssi SILC client of asynchronous public key
2519 verification and passphrase inquiry. Affected file is
2520 irssi/src/silc/core/silc-core.c.
2522 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Do not say "You have left channel %s" in client library.
2525 Moved it to the application. Affected files are
2526 lib/silcclient/command.c and silc/client_ops.c.
2528 * Fixed silc_client_get_clients. Command context was not
2529 duplicated and was freed memory in the callback. Affected
2530 file lib/silcclient/idlist.c.
2532 * Do not say "you are now talking..." on JOIN command in the
2533 client library. The appliation must handle it.
2535 * Do not say ".. changed topic to" in command reply in the
2536 client libary. The application must handle it.
2538 * Fixed TOPIC command sending in the client library.
2540 * Fixed a memory leak in silc_client_command_free in the file
2541 lib/silcclient/command.c.
2543 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Imported a modified version of Irssi client to the source tree.
2546 The Irssi will be used to create a new client called
2547 Irssi SILC. Imported to irssi/.
2549 Added silc_core_init_finish function to the Irssi. Affected
2550 file irssi/configure.in.
2552 A lot changes in the Makefile.ams around the irssi tree.
2554 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Do not rehash if the new size is same as the old size of the
2557 hash table, in the silc_hash_table_rehash*. The affected file
2558 lib/silcutil/silchashtable.c.
2560 * Replaced hash_table_del_by_context calls from the server
2561 (when channel->user_list and client->channels) to the
2562 hash_table_del as it is sufficient and faster.
2564 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Added silc_hash_table_list, silc_hash_table_get and the
2567 SilcHashTableList structure to provide an alternative way to
2568 traverse the hash table. The affected files are
2569 lib/silcutil/silchashtable.[ch].
2571 * Changed the server's idlist routines to use the hash table
2572 routines to optimize the code.
2574 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Replaced the client entry's `channel' list and channel entry's
2577 `user_list' list to hash tables for optimized lookup. Changed
2578 the code to use the hash table interface around the code.
2579 Affected file lib/silcd/idlist.[ch].
2581 * Added `auto_rehash' boolean argument to the function
2582 silc_hash_table_alloc to indicate whether the hash table should
2583 auto-rehash when it thinks is appropriate time. It will
2584 increase the hash table size if the there is twice as much
2585 entries in the table than the size of the table, and will
2586 decrease the size if there are twice as less entries than
2587 the size of the table.
2589 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2593 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * silc_idcache_purge_by_context deletes the entry now by context
2596 as it is supposed to do. Affected file lib/silccore/idcache.c.
2598 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2599 client is not anymore valid (WHOWAS givens the info) and not
2600 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2602 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Removed the `data' and `data_len' arguments from the ID Cache
2605 interfaces and added `name' argument. ID Cache does not handle
2606 anymore the binary data only a names associated with given ID.
2608 * When hashing a Client ID with silc_hash_id the entire ID is
2609 not hashed anymore, instead only the hash of the Client ID is
2610 hashed. This way we can access the Client ID from the cache
2611 with Client ID but with the hash of the ID (which is a hash of
2612 the nickname) as well without any difference in performance.
2614 Added also silc_idcache_find_by_id_one_ext to do one on one
2615 searching when we have the actual ID. Added also function
2616 silc_hash_client_id_compare. The affected files are
2617 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2619 * When hashing the name associated with a ID it is always done
2620 in lowercase. This way we can access the cache without worrying
2621 about case-sensitivity, even though, for example nicknames are
2624 * Fixed a bug in server with channel message sending. It put
2625 wrong ID type as destination ID. The affected file
2626 silcd/packet_send.c.
2628 * silc_idcache_del_by_context now deletes from all hash tables
2629 by context. Affected file lib/silccore/idcache.c.
2631 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Changed the client library to use the new ID Cache interface.
2634 Changes around the source tree.
2636 * Added silc_hash_table_rehash_ext to rehash with specific
2637 hash function. Affected file lib/silcutil/silchashtable.[ch].
2639 * Added silc_hash_string_compare to compare two strings in the
2640 hash table. Affected file lib/silcutil/silcutil.[ch].
2642 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added new function silc_idcache_del_by_context into the
2645 lib/silccore/idcache.[ch].
2647 * Changed the server's ID list routines to use the new ID Cache
2648 interface. Changes around the source tree.
2650 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added silc_hash_table_del[_by_context]_ext functions in to the
2653 lib/silcutil/silchashtable.[ch].
2655 Removed silc_hash_table_find_all* routines and added new
2656 silc_hash_table_find_foreach to replace them.
2658 Added silc_hash_table_replace_ext function as extended
2659 replacing function. Separated the simple hash table interface
2660 from the extended hash table interface in the file
2661 lib/silcutil/silchashtable.h.
2663 * Fixed minor bugs and changed it to use some of the new
2664 hash table functions in lib/silccore/idcache.c
2666 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Added new function silc_hash_table_find_all to return all keys
2669 in the hash table by the specified key. As the hash table is
2670 collision resistant it also makes it possible to have several
2671 duplicate keys in the hash table. This function may be used to
2672 find all of the keys from the hash.
2674 Added user_context arguments to the SilcHashFunction,
2675 SilcHashCompare and SilcHashDestructor to deliver user specified
2678 Added new fuctions silc_hash_table_find[_all]_ext to do
2679 extended lookup with specified hash and compare functions and
2680 specified user contexts.
2682 Added new function silc_hash_table_add_ext to add the key
2683 with specified hash function and user context.
2685 Added new function silc_hash_table_foreach to traverse all
2686 entrys in the hash table. Added SilcHashForeach callback
2689 Added new function silc_hash_table_del_by_context to delete
2690 the entry only if the context associated with the key matches.
2692 Affected files are lib/silcutil/silchashtable.[ch].
2694 * Removed silc_hash_[server/client/channel]_id and added just
2695 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2696 silc_hash_id_compare to compare two ID's using as the hash table
2697 comparison function. Added also silc_hash_data to hash
2698 binary data and silc_hash_data_compare to compare it.
2700 * Removed silc_idlist_find_client_by_hash as it is not needed
2701 anymore. Affected file silcd/idlist.[ch].
2703 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2704 to use internally the SilcHashTable. The new ID Cache is a lot
2705 faster than the old one. Some of the ID Cache interface was also
2706 rewritten and obsolete and stupid functions were removed.
2708 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Added entry_count field to the SilcHashTable to keep the number
2711 of the entries in the table. Implemented the function
2712 silc_hash_table_rehash. Added new function
2713 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2715 Fixed a minor bug in silc_hash_table_free.
2717 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2718 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2719 into the lib/silcutil/silcutil.[ch].
2721 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Implemented a collision resistant hash table into the
2724 lib/silcutil/silchashtable[ch]. See the header and the source
2725 for the SilcHashTable API.
2727 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Merged dotconf version 1.0.2 into lib/dotconf.
2731 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Do not compile anything in lib/silcsim/* if the SIM support
2734 is not enabled. The tree should now compile without problems
2737 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Compiled the SILC under cygwin. Compiled and tested briefly
2740 without problems. More tests needed. The SIMs didn't compile
2743 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2745 * Fixed possible crash in silc_get_username in the
2746 lib/silcutil/silcutil.c.
2748 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Fixed a va_arg in silc/client_ops.c.
2752 * Oops, RC5 routines were named AES and caused some problems
2753 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2755 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Added new SilcIDIP structure into the lib/silccore/id.h and
2758 replaced the old `ip' fields from all SILC ID's to that type.
2759 This is a step towards IPv6 support.
2761 The silc_id_get_len takes now the ID as an extra argument.
2762 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2763 both IPv4 and IPv6 based ID's.
2765 The affected files are lib/silccore/id.[ch] and other files
2766 around the tree using these routines.
2768 * Removed the ID length arguments in server from various
2769 silc_server_send_notify_* routines -> they are not needed
2772 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Fixed memory leak in silc_encode_pem_file in the file
2775 lib/silcutil/silcutil.c.
2777 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Check minor version as well in the SKE. Affected files are
2780 silcd/protocol.c and lib/silcclient/protocol.c.
2782 * Added --identifier option to the server so that an identifier
2783 can be when creating the public key for the server. Affected
2784 file is silcd/silcd.c.
2786 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2787 lib/silccrypt/silcpkcs.c.
2789 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Register default ciphers and stuff when using -C option with
2792 the server. Affected file sildc/silcd.c.
2794 * Put back the servers public key filename format, it is better
2795 than the new one. For now, the client keys are saved with the
2796 new filename format. The affected file silc/client_ops.c.
2798 * Implemented the Cipher API for the rest of the ciphers that
2799 did not implement it or implemented it the wrong way.
2801 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Register default ciphers and stuff when using the -S option
2804 in the client. Affected file silc/silc.c. Same also when
2805 creating new key pair with -C option.
2807 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Fixed the silc_verify_public_key client operation function to
2810 save the public keys differently. The fingerprint is now
2811 used as filename and not the hostname. This way also the
2812 client keys are saved uniquely and not with hostnames. The
2813 affected file is silc/client_ops.c.
2815 * Trimmed the silc_hash_fingerprint function to remove extra
2816 whitespaces from the end of the fingerprint. The affected
2817 file is lib/silccrypt/silchash.c.
2821 * Added silc_cipher_register_default function to register all
2822 default ciphers. It can be used when configuration files
2823 does not exist and the application does not want any specific
2824 ciphers in any specific order.
2826 The SilcDList is now used as silc_cipher_list dynamically
2827 allocated cipher list. Removed the static list all together
2828 and now all ciphers must be allocated to the dynamic list.
2829 The silc_cipher_alloc routine was changed to check only the
2832 All silc_cipher_* routines that used to return int returns
2835 The affected files lib/silccrypt/silccrypt.[ch].
2837 * The same thing was done to silc_hash_* as for silc_cipher_*
2838 routines. Affected files lib/silccrypt/silchash.[ch].
2840 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2841 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2842 Added also silc_pkcs_[un]register[_default] functions.
2843 Removed the data_context from the PKCS API.
2845 * Added silc_hmac_register_default function to register default
2846 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2847 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2848 to unregister all hmacs at once.
2850 * Register the default ciphers, hash functions, PKCSs and HMACs
2851 if client's configuration file does not exist. The affected
2854 * The client did not load the hash functions from the SIM
2855 modules at all. Added support for this. Affected file is
2856 silc/clientconfig.c.
2858 * When decoding public key with silc_pkcs_public_key_decode, check
2859 the supported algorithm only if PKCS are registered. Affected
2860 file lib/silccrypt/silcpkcs.c. The same was done with the
2861 silc_pkcs_private_key_decode.
2863 * Fixed the SILC List routines to keep the list always in order.
2864 It used to change the list's order when traversing the list but
2865 not it preserves the order. Affected file lib/trq/silclist.h.
2867 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Added the client library to use the SilcSocketConnection's
2870 reference counter (by silc_socket_dup) to prevent the bug that
2871 the socket object may be freed underneath async operation.
2873 * The name resolv library checking fixes in the configure.in.pre.
2876 * Created new version of the protocol drafts for future
2877 development. The -03 drafts are the ones that will be changed
2878 in the trunk now and the -02 will remain as they are.
2880 * Send list of CUMODE notifys to the router when announcing
2881 the channel users to the router. Affected file silcd/server.c.
2882 If the router receiving channel founder CUMODE for a channel
2883 that already has channel founder it will send CUMODE notify
2884 to the sender to remove the channel founder rights from the
2885 announced client. Affected file silcd/packet_receive.c.
2887 * The CUMODE notify may now use Server ID as well as the entity
2888 who changes the mode. Updated protocool specs.
2890 * Updated INSTALL and README files.
2892 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * New web pages in the http://silc.pspt.fi. The pages was
2899 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Implemented the [DenyConnectin] config section in the server.
2902 Added silc_server_config_denied_conn to check whether incoming
2903 connection is denied. Affected file silcd/serverconfig.[ch].
2905 * Do not check the ports when checking the incoming configuration
2906 data if the port is 0, meaning any. Affected file is
2907 silcd/serverconfig.c.
2909 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Fixed buffer overflow in silc_string_compare in the file
2912 lib/silcutil/silcutil.c.
2914 * Fixed double free in silc_server_command_leave in the file
2917 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Fixed the version checking in the server. Affected file is
2922 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Fixed the configuration data fetching when accepting new
2925 connections in the server. Affected file silcd/server.c.
2927 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Added `sender_entry' argument to the function
2930 silc_server_packet_relay_to_channel so that we can check
2931 whether some destination actually belongs to the same route
2932 the sender belongs (ie, we must not resend the packet to the
2933 sender). Affected file silcd/packet_send.[ch].
2935 * Added `servername' field to the SilcClientEntry in the server
2936 to hold the name of the server where client is from. Affected
2937 file is silcd/idlist.h.
2939 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Moved the channel message encrypting in the router betwen
2942 router connections from silc_server_channel_message to the
2943 silc_server_packet_relay_to_channel since we want to check
2944 whether we have anybody channel before encrypting anything.
2945 Affected files silcd/packet_[receive/send].c.
2947 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Fixed the [AdminConnection] server config section to support
2950 multiple entries. Affected file silcd/serverconfig.c.
2952 * Added support into the server to check the validity of the
2953 incoming connection before executing any KE or authentication
2956 * The connection configuration is now saved to the KE and
2957 connection auth protocol contexts and not fetched anymore in
2958 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2960 * The local hosts listenning address and port is also resolved
2961 now when starting the server. We want to have the socket object
2962 to include the real address and port for the listener. Added
2963 new function silc_net_check_local_by_sock into the files
2964 lib/silcutil/silcnet.[ch].
2966 * Fixed a broadcast bug in server -> do not broadcast if we
2969 * Fixed a routing bug. Do not route broadcast packets ever.
2970 Broadcast packets must be processed always and not routed since
2971 they may be destined to some other host than yourself and thus
2972 would get routed without no good reason. Affected file is
2975 * Added function silc_server_config_is_primary_route to check
2976 whether primary router connection has been configured (a router
2977 configuration that we are initiating). If there is not, we
2978 will assume that there is only two routers in the SILC network
2979 and we will use the incoming router connection as our primary
2980 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2982 * Changed the order of the broadcasting. Broadcast _after_ the
2983 packet has been processed not before. Affected file is
2986 * Fixed a [ClientConnection] parsing bug. The port was never
2987 parsed correctly thus resulting to port 0. Affected file
2988 silcd/serverconfig.c.
2990 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2991 argument and did not set the broadcast packet flag. Affected
2992 file silcd/packet_send.c. Fixed same bug in the function
2993 silc_server_send_notify as well.
2995 * If we receive NEW_ID packet for our own ID in the server, ignore
2998 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Removed the nickname from the Private Message Payload.
3003 Updated the code and the protocol specs.
3005 * Updated protocol specs for submitting to the IETF.
3007 * Tweaked the Random Number Generator a bit. Affected file
3008 lib/silccrypt/silcrng.c. Exported a new function
3009 silc_rng_[global]_add_noise which can be used to add more
3012 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Do not parse packets with different timeout when protocol
3015 is active -> may cause problem with rekey. Affected file
3018 * When server receives signoff notify it must not create
3019 new channel key if the client is on any channels since the
3020 sender of the signoff notify will create it.
3022 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Added printing of error messages during SKE protocol from the
3025 failure packet sent by server during SKE. Affected file
3028 * Removed the client's failure_callback handling with timeout
3029 and handle it immediately when received.
3031 * The SKE library returned wrong type in SUCCESS and FAILURE
3032 packets. They must be 32 bit MSB not 16 bit MSB.
3034 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Ok, rewrote the logic of the re-key and now it seems to work.
3037 I tested it on high traffic with frequent re-keys without
3038 problems. Added hmac_receive (and renamed hmac to hmac_send)
3039 in SilcClientConnection in lib/silcclient/client.h and
3040 in SilcIDListData in silcd/idlist.h. Also, removed the
3041 SilcPacketParserContext's cipher and hmac fields as they are
3042 not needed anymore and actually caused some problems when
3043 the ciphers and hmac's changed underneath the packet parser.
3045 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * If re-key protocol is active then process the incoming packets
3048 synchronously since we must assure that icoming packets encrypted
3049 with the old key is processed before the new keys is set to
3050 use. This is true other packets than for REKEY packets.
3051 Affected file silcd/server.c. The same was done to client library
3052 as well, affected file lib/silcclient/client.c.
3054 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Fixed bug in client and server to accept the force send if
3057 the packet is send from silc_[server/client]_packet_process
3058 function. Otherwise the packets are never delivered, oops.
3060 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Disable force sending of packets when REKEY protocol is active.
3063 We must assure that no packet is sent directly when rekey is
3064 performed. All packets must be sent through packet queue.
3065 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3066 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3067 function is silc_[server/client]_packet_send_real to check
3070 * Replaced the SIM paths from example config files to
3071 /usr/local/modules. Also, make install creates now
3072 /usr/local/silc/logs directory to hold all the SILC server
3075 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Made the configure.in.pre work on Solaris. Patch by salo.
3079 * Made all ciphers compatible with non-x86 machines. Defined
3080 CBC mode macros into lib/silccrypt/ciphers_def.h.
3082 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Fixed the make install.
3086 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * When MAC computation fails the silc_packet_decrypt returned 0
3089 even though it was supposed to return -1. Fixed this. The
3090 affected file is lib/silccore/silcpacket.c.
3092 * Do not replace the config files in /etc/silc (in make install)
3093 if they already exist. Affected file ./Makefile.am.
3095 * Do not send re-key packets immediately but through packet queue.
3096 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3098 * Changed silc_net_check_host_by_sock to return FALSE if the
3099 IP/DNS could not be resolved. Though, it returns the IP address
3100 now even if it could not resolve it (but returns also FALSE).
3101 Affected file lib/silcutil/silcnet.[ch].
3103 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Added silc_pkcs_decode_identifier to decode the public key's
3106 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3107 Added also silc_pkcs_free_identifier. Added also new context
3108 SilcPublicKeyIdentifier.
3110 * Added -S option to the silc client. It is used to dump the
3111 contents of the specified public key file.
3113 * Changed the PKCS api to return the public key length when
3114 setting the public key.
3116 * Fixed a fatal bug in the public and private key file loading.
3117 Affected file lib/silccrypt/silcpkcs.c.
3119 * Execute the packet parsing for client with zero (0) timeout
3120 if the protocol is active. Affected file silcd/server.c.
3122 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Made the key generation options to the silcd program. Added
3125 -C option, equivalent to client's option.
3127 * Added new [ServerKeys] config section to the server. It
3128 configures the server's public and private key.
3130 * Defined generic Public Key Payload into the protocol
3131 specification to send specific type of public keys and
3134 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3135 public key or certificate.
3137 * Implemented the GETKEY command to the server and to the
3138 client library and on user interface.
3140 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * Made preliminary `make install' work.
3144 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Added SilcServerRekey context into silcd/idlist.h.
3148 * Added the PFS support as defined in the specification to the
3149 SKE protocol. Affected files lib/silcske/*.c.
3151 * Added `ske_group' field to the SilcServerRekey context to hold
3152 the number of the SKE group that is used with PFS in re-key.
3153 Affected file silcd/idlist.h.
3155 * Added PFS re-key support to the server. Affected file is
3158 * Added silc_protocol_cancel to cancel execution of the next
3159 state of the protocol. Affected file is
3160 lib/silccore/silcprotocol.[ch].
3162 * Added the re-key support with and without PFS to the client
3163 library. Re-key is performed once in an hour, by default.
3165 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3166 Added silc_client_rekey_callback and silc_client_rekey_final.
3167 Affected files are lib/silcclient/protocol.[ch] and
3168 lib/silcclient/client.[ch].
3170 * Removed the `hmac_key' and `hmac_key_len' fields from the
3171 SilcClientConnection structure; not needed. Affected file is
3172 lib/silcclient/client.h.
3176 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Do not ask whether user wants to use the negotiated private key
3179 for private messages, just use it. Affected file is
3180 silc/local_command.c.
3182 * Added `send_enc_key' and `enc_key_len' fields to the
3183 SilcIDListData structure since they are needed in the re-key
3184 phase. Affected file is silcd/idlist.[ch].
3186 * Implemented the simple re-key protocol into the server.
3187 Affected files silcd/server.c and silcd/protocol.[ch]. The
3188 re-key will be performed once in an hour, by default.
3190 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3191 Added silc_server_rekey, silc_server_rekey_callback and
3192 silc_server_rekey_final.
3194 * Removed Tunneled flag from the protocol. Updated the code
3195 and the specifications.
3197 * Adde `pfs' field to the SilcIDListData to indicate whether
3198 the PFS is to be performed in the re-key. Affected file is
3201 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3204 int64 of at least the xintXX size. If void * is less that 4
3205 bytes uint32 * will be used. Defined bool as boolean.
3207 * Changed _ALL_ unsigned long and unsigned int to uint32,
3208 unsgined short to uint16 in the source tree.
3210 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3211 not handle clients that has entry->data.registered == FALSE.
3212 They are not in the network anymore. Affected file is
3215 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Implemented the sending of the SERVER_SIGNOFF notify in the
3218 server. Affected file is silcd/server.c.
3220 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3221 Added also silc_notify_payload_encode_args into the
3222 lib/silccore/silcnotify.[ch].
3224 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3225 Affected file silcd/packet_receive.c.
3227 * Implemented the SERVER_SIGNOFF notify handling in the client
3228 library. Affected file lib/silcclient/client_notify.c. Also,
3229 implemnted the printing of the SERVER_SIGNOFF info to the
3230 application. Affected file silc/client_ops.c.
3232 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3233 if the deleting was successful. Affected file silcd/idlist.[ch].
3235 * Added support for public key authentication in the connection
3236 authentication protocol in the client library. Affected file
3237 lib/silcclient/protocol.c.
3239 * Changed the server's silc_idlist_get_clients_by_* interface
3240 to support already allocated array so that new entries may be
3241 added to pre-allocated array. Affected file silcd/idlist.[ch].
3242 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3243 and command replies.
3245 * All command reply functions in the server now calls the
3246 pending command callback even if error occured. This way the
3247 error will be delivered to the client as well. Affected files
3248 silcd/command.c and silcd/command_reply.c.
3250 * Fixed INFO command to return local server's info if no server
3251 was provided. Affected file lib/silcclient/command.c.
3253 * Removed RESTART command for good. Updated the code and the
3256 * Rewrote parts of the task system. It is a bit simpler now.
3257 Removed unsued task priorities. The affected files are
3258 lib/silcutil/silctask.[ch].
3260 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Moved the USERS printing from the library to the application.
3263 Affected files lib/silcclient/command.c and silc/client_ops.c.
3265 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Added channel key re-key support. The re-key is perfomed
3270 only by the router and is done once in an hour. Added `rekey'
3271 field to the SilcChannelEntry in the server. Affected files
3272 silcd/server.c and silcd/idlist.h.
3274 * Added silc_task_unregister_by_context into the file
3275 lib/silcutil/silctask.[ch].
3277 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Added SILC_UMODE_GONE mode to indicate when the client is not
3280 present in the SILC network. Added also support to the local
3281 command AWAY that will set this mode. Added support of showing
3282 "xxx is gone" in WHOIS command. The USERS command shows the
3283 gone status as well.
3285 * Fixed setting server and router operator privileges in the
3286 server's UMODE command. Affected file silcd/command.c.
3288 * Merged the SKE KE1 and KE2 payloads into one payload. The
3289 new KE payload is equivalent to the old KE2 payload.
3291 Cleaned up the SKE Start Payload parsing. It now uses the
3292 simple buffer unformatting to do the parsing. A lot faster
3295 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3296 to the SKE that is used to indicate whether both of the SKE
3297 parties should perform authentication. By default only the
3298 responder performs authentication. By setting this flag also
3299 the initiator must do authentication. By default it is unset
3300 since in normal SKE case, client to server connection, only
3301 the responder should do authentication. When doing SKE between
3302 two clients both should perform authentication. Updated the
3303 code and the protocol specs.
3305 * A little fix to IDENTIFY command in the server. Search the
3306 client first by hash not nickname. Affected file is
3309 * Fixed the silc_client_close_connection to support closing
3310 the client to client connections wihtout deleting too much
3311 data. Affected file lib/silcclient/client.c.
3313 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3314 are received if protocol used to be active but is not anymore
3315 the application would crash due to NULL pointer dereference.
3316 Affected files silcd/server.c and lib/silcclient/client.c.
3318 * Added `hash' field to the SilcClientConnection to include
3319 the hash function negotiated in the SKE protocol.
3321 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3322 to set the channel founder authentication data. A client can
3323 claim the founder rights later by providing the authentication
3324 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3325 This way the channel founder can regain the channel founder
3326 privileges even it is left the channel. This works only on
3327 local server and the client must be connected to the same
3328 server to be able to regain the founder rights. Updated the
3329 protocol specs accordingly.
3331 Added support to the CMODE command in the client to set the
3332 founder auth data. Read the README to see how to set it.
3334 Added support to the CUMODE command to claim the founder
3335 rights. Read the README to see how to do it.
3337 Added support for the founder authentication to the Channel
3338 Entry in the server. Affected file silcd/idlist.h.
3340 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3341 server's CMODE command. Affected file silcd/command.c.
3343 * Added the following new functions into lib/silccore/silcauth.[ch]:
3344 silc_auth_get_method and silc_auth_get_data.
3346 * The server now saves the remote hosts public key to the
3347 SilcIDListData pointer. Affected file silcd/protocol.c.
3349 * The normal server now does not remove the channel entry from
3350 the cache if the founder authentication data is set. It used
3351 to remove it if the founder was the last one on the channel on
3352 the server and left the channel. The auth data is saved and
3353 if the channel is re-joined later the old entry is used with
3354 the old auth data. Affected files silcd/command_reply.c and
3357 * Removed the `pkcs' field from the SilcIDListData structure
3358 in the server; it is not used. Affected file silcd/idlist.h.
3360 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Fixed packet processing on slow links. Partial packets were
3363 never re-processed because the incoming data buffer was cleared
3364 by the application. Application must not directly clear the
3365 sock->inbuf, the packet processing routines handle it. Fixed
3366 this in client library and in server.
3368 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Fixed the WHOIS and IDENTIFY send reply function to really
3371 check whether to send list or just one entry. Affected file
3374 * Cleaned up the LEAVE command's channel key distribution. The
3375 affected file silcd/command.c.
3377 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3378 can enforce the channel mode as well. In that case the ID
3379 includes the ID of the server. The code now enforces the
3380 mode change if the router have different mode than the server.
3382 * The notify client operation with CMODE_CHANGE notify can now
3383 return NULL client_entry pointer if the CMODE was not changed
3384 by client. Application must check for this.
3386 * Added <Server ID> argument to INFO command to support server
3387 info fetching by Server ID.
3389 * Added silc_server_announce_get_channel_users to get assembled
3390 packets of channel users of the specified channel. Affected
3391 file silcd/server.[ch].
3393 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3394 was freed underneath the ID Cache.
3396 * Re-announce clients when the server received CHANNEL_CHANGE
3397 notify from the router. Affected file silcd/packet_send.c.
3399 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3402 crashed since it did not handle the fact that there is no cipher
3403 called "3" and didn't check the error condition. Now fixed.
3405 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3406 flag. It can be used to send message requests.
3408 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Implemented the RESTART command in the client.
3412 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3413 notice type messages. Added notice printing to the user
3416 * The channel keys are not re-generated if the channel's mode
3417 is PRIVKEY, ie private key on the channel exists. Affected
3418 files silcd/server.c and silcd/command.c.
3420 * Fixed a little bug in channel message delivery when channel
3421 private keys are set in the server. Affected file is
3422 silcd/packet_send.c.
3424 * Changed the setting on channel->on_channel = TRUE from the
3425 silc_client_save_channel_key to the JOIN command reply. The
3426 key payload is not received if the private channel key is set.
3427 Affected file lib/silcclient/command_reply.c and the
3428 lib/silcclient/client_channel.c.
3430 * When the CMODE_CHANGE notify is sent and the channel private
3431 key mode is removed the channel key must be re-generated in
3432 other cells as well. Added this support for the router in the
3433 silcd/packet_receive.c.
3435 * Added new local command NOTICE to send notice message on
3436 channel. Affected file silc/local_command.[ch].
3438 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Added new local command ME to the client. It is used to send
3441 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3442 some action. Affected file silc/local_command.[ch].
3444 * Changed channel_message and private_message client operations
3445 to deliver the message flags to the application. Added also
3446 the `flags' arguments to the silc_client_send_channel_message
3447 and silc_client_send_private_message functions. Affected file
3450 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Redefined the Private Message Payload to support private message
3453 keys and to support the new private message flags. Updated
3454 the protocol specs. Flags makes it possible to have for example
3455 CTCP style messages.
3457 * Added new type SilcPrivateMessagePayload and defined an API
3458 for it in the lib/silcclient/silcprivate.[ch].
3460 * Tested private message private keys successfully. Tested the
3461 private message key set, unset and list commands with the new
3464 * Redefined the Channel Message Payload to include the channel
3465 message flags (equal with private message flags) to support
3466 for example CTCP style messages.
3468 * Defined some of the message (for channel and private message)
3469 flags. Updated the protocol specs and added the flags to the
3470 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3472 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Added SilcKeyAgreementStatus type to the key agreement routines
3475 to indicate the current status and error if one occured.
3476 The status types are defined in the lib/silcclient/silcapi.h.
3478 * Added new local command KEY that is used to set and unset private
3479 keys for channels, set and unset private keys for private messages
3480 with remote clients and to send key agreement requests and
3481 negotiate the key agreement protocol with remote client. The
3482 key agreement is supported only to negotiate private message keys,
3483 it currently cannot be used to negotiate private keys for channels,
3484 as it is not convenient for that purpose.
3486 * Fixed a minor pending callback setting bug in the function
3487 silc_client_get_client_by_id_resolve, now the function works.
3488 Affected file lib/silcclient/idlist.c.
3490 * Added function silc_net_get_local_port to get local bound
3491 port by socket. Added to lib/silcutil/silcnet.[ch].
3493 * Added `sockets' and `sockets_count' fields to the SilcClient
3494 object. They hold the sockets of the listenning sockets in
3495 the client. Listenning sockets may be for example the key
3496 agreement server. Affected file lib/silcclient/client.[ch].
3497 Added functions the silc_client_add_socket and the
3498 silc_client_del_socket. They are exported to the application
3501 * Added ~./silc/clientkeys to support other client's public keys.
3503 * Renamed verify_server_key client operation to verify_public_key
3504 and added one argument to indicate the type of the connection
3505 (server, client etc.).
3507 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3509 * Added silc_server_connection_auth_request to handle the
3510 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3511 silcd/packet_receive.[ch].
3513 * Added silc_server_send_connection_auth_request into the
3514 silcd/packet_send.c to send the connection auth request packet.
3516 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3519 * Fixed the public key authentication in responder side in the
3520 server. The `auth_data' pointer includes the SilcPublicKey
3521 not the path to the public key. Affected file silcd/protocol.c.
3523 * Implemented the public key authentication in the initiator side
3524 in the server. Affected file silcd/protocol.c.
3526 * Removed the [RedirectClient] config section from the server
3527 configuration. Is not needed and I don't want to implement it.
3529 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Cleaned up the CMODE command in the server. It now works
3532 correctly and supports all the modes defined in the protocol.
3533 Affected file is silcd/command.c.
3535 * Added `hmac_name' field to the SilcChannelEntry in the server
3536 to hold the default HMAC of the channel. It can be set when
3537 creating the channel (with JOIN command). Affected files
3540 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3541 type to indicate the change of the current cipher and hmac
3542 on the channel. Client can safely ignore the <cipher> argument
3543 (if it chooses to do so) since the CHANNEL_KEY packet will
3544 force the channel key change anyway. The <hmac> argument is
3545 important since the client is responsible of setting the new
3546 HMAC and the hmac key into use.
3548 * Fixed the CMODE command in the client library as well.
3550 * Tested CMODE command in router environment successfully.
3552 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Show the version of the remote client (or server) when connecting
3555 to the server. It is logged to the log file. Affected file
3556 is silcd/protocol.c.
3558 * Fixed the KILLED notify handling in the client library. The
3559 client must be removed from all channels when receiving the
3562 Also, do not remove the client entry when giving the KILL
3563 command but when the KILLED notify is received.
3565 * Removed silc_idlist_find_client_by_nickname from the server.
3566 Not needed anymore. Affected files silcd/idlist.[ch].
3568 * Implemented the CHANNEL_CHANGE notify type handling to the
3569 server. Affected file silcd/server.c.
3573 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Added silc_server_send_notify_invite to send the INVITE
3576 notify between routers.
3578 * Implemented the INVITE command correctly to the server.
3580 * Implemented the INVITE notify type handling in the server.
3582 * Implemented the INVITE command to the client library and on the
3585 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Added function silc_server_get_client_resolve to find the
3588 client entry by ID from all ID lists and then resolve it
3589 (using WHOIS) if it cannot be found. Affected file is
3592 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Implemented the BAN command to the client library.
3596 * The JOIN command in the server now checks the invite list
3599 * Changed the silc_command_reply_payload_encode_va and the
3600 silc_command_payload_encode_va to support that if argument is
3601 NULL it ignores and checks the next argument. Affected file
3602 lib/silccore/silccommand.c.
3604 * Added silc_server_send_notify_ban to send the BAN notify
3605 type between routers.
3607 * Chaned the silc_notify_payload_encode to support that if
3608 argument is NULL it ignores and checks the next argument.
3609 Affected file lib/silccore/silcnotify.c.
3611 * Tested ban lists in router environment successfully.
3613 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Implemented BAN command to the server, in silcd/command.[ch].
3617 * Removed the BAN and INVITE_LIST modes from the CMODE command
3620 * Added function silc_string_match to regex match two strings.
3621 Affected files lib/silcutil/silcutil.[ch].
3623 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Redefined parts of the SilcChannelEntry in the server to support
3626 the new ban and invite lists.
3628 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Redefined the INVITE command. The same command can be used to
3631 invite individuals to the channel but also to manage the invite
3632 list of the channel (to add to and remove from the invite list).
3633 Updated the protocol specs.
3635 * Added new command SILC_COMMAND_BAN that can be used to manage
3636 the ban list of the channel. Updated the protocol specs.
3638 * Removed the channel modes: the SILC_CMODE_BAN and the
3639 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3640 in the CMODE command. The equivalent features are now available
3641 using INVITE and BAN commands. Updated the protocol specs.
3643 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3644 in the network about change in the current ban list. The notify
3645 type is not used by the client.
3647 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3648 support the invite lists.
3650 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added new function silc_string_regexify that converts string
3653 including wildcard characters into regex string that can
3654 be used by the GNU regex library. Added into the file
3655 lib/silcutil/silcutil.[ch].
3657 Added silc_string_regex_combine to combine to regex strings
3658 into one so that they can be used as one regex string by
3659 the GNU regex library. Added into the file
3660 lib/silcutil/silcutil.[ch].
3662 Added silc_string_regex_match to match two strings. It returns
3663 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3665 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Imported GNU regex to the soruce tree into lib/contrib.
3668 Fixed some compiler warning from the regex.c.
3670 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Fixed MOTD command in the server to work in router environment.
3674 * Fixed the MOTD command in the client library to support
3675 the server argument in the command.
3677 * Added `nickname_len' argument to the silc_idlist_add_client
3678 in the server, as the `nickname' argument may be binary data
3681 * Added silc_idlist_get_channels to return all channels from
3684 * Implemented LIST command to the server. Affected file is
3687 * Implemented the LIST command to the client library and on the
3690 * Added [<user count>] argument to the LIST command reply.
3691 With private channels the user count is not shown.
3693 * Updated TODO and README.
3695 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * The client entry's data.registered must be TRUE even with
3698 global client entry on global client list. The data.registered
3699 is used to check whether the client is anymore in the network,
3700 for example with WHOWAS command so it must be valid.
3702 * Fixed the WHOWAS command in the server. It now actually works
3703 in router environment. Added function into silcd/command_reply.c
3704 silc_server_command_reply_whowas_save.
3706 * Added silc_idlist_purge function to the silcd/idlist.c
3707 to periodically purge the ID Cache.
3709 * Fixed INFO command in the server. It works now in router
3710 environment. Added <server name> argument to the INFO command
3711 reply. Updated the protocol specs.
3713 * Fixed minor bug in silc_idcache_purge to not purge if the
3714 expire value is zero.
3716 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3717 they were buggy because of the WHOWAS information.
3719 * Fixed local command MSG to handle the async resolving of
3720 the remote client properly. It used to fail the first MSG.
3721 Affected file silc/local_command.c.
3723 * Added `data_len' field to SilcIDCache context.
3725 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Update TODO. Todo in commands in the server.
3729 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3732 used by routers as broadcast packet to inform other routers
3733 about the changed user mode.
3735 Implemented the notify handling in the server. Affected file is
3736 silcd/packet_receive.c. Added the function
3737 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3739 * Added new generic Channel Payload and deprecated the New Channel
3740 Payload. The New Channel Payload is now the generic Channel
3743 * Added new argument `mode' to the silc_server_send_new_channel
3744 as it is required in the Channel Payload now.
3746 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3747 and created a new and real SilChannelPayload to represent the
3748 new generic Channel Payload. Implemented the encode/decode
3749 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3751 * Added silc_server_get_client_channel_list to return the list
3752 of channels the client has joined for WHOIS command reply.
3753 Affected file silcd/server.[ch].
3755 * Implemented the channel list sending in the WHOIS command reply
3756 in server and in the client.
3758 Implemented the channel list displaying on the user interface
3759 as well. Affected file silc/client_ops.c.
3761 * Added silc_channel_payload_parse_list to parse list of Channel
3762 Payloads. It returns SilcDList list of SilcChannelPayloads.
3763 Client for example can use this function to parse the list of
3764 channels it receives in the WHOIS command reply. The caller
3765 must free the list by calling silc_channel_payload_list_free.
3766 Affected files lib/silccore/silcchannel.[ch].
3768 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Added one new argument <user mode> to the WHOIS command reply
3771 to return the mode of the user in SILC. Updated the protocol
3774 Implemented it to the server and client.
3776 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Fixed the mode printing on the user interface on joining.
3779 Affected file silc/client_ops.c.
3781 * Implemented the UMODE command and user modes in general to the
3782 client library and to the user interface.
3784 * Implemented the UMODE command to the server.
3786 * The server now sends UNKNOWN_COMMAND error status if client sends
3787 unknown command. Affected file silcd/command.c.
3789 * All server commands now handle the command identifier the right
3790 way when sending the command reply to the client. The client can
3791 use to identify the command replies with the identifier.
3793 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Added silc_server_get_client_route to resolve the route to
3796 the client indicated by the client ID. Affected file is
3799 * Added silc_server_relay_packet as general function to relay
3800 packet to arbitrary destination. This deprecates functions
3801 like _send_private_message_key, _relay_notify etc. Affected
3802 file is silcd/packet_send.[ch].
3804 Removed silc_server_send_key_agreement,
3805 silc_server_send_private_message_key and
3806 silc_server_packet_relay_notify functions from the file
3807 silcd/packet_send.[ch].
3811 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3812 server. Affected file silcd/packet_receive.[ch].
3814 * Implemented the KILL command to the client. Implemented the
3815 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3816 Affected files lib/silcclient/command[_reply].c and
3817 lib/silcclient/client_notify.c. Implemented the KILL notify
3818 printing in the user inteface.
3820 * Fixed a lot silc_parse_nick memory leaks from the client
3821 library in the file lib/silcclient/command.c.
3823 * Changed the silc_server_send_notify_on_channels's `sender'
3824 argument from SilcSocketConnection to SilcClientEntry to
3825 check the sender as entry and not as connection object and not
3826 to send to the client provided as argument. The affected file
3827 is silcd/packet_send.[ch].
3829 * The notify packets that are destined directly to the client used
3830 to not to be processed by the server. Now changed that and the
3831 server processes all notify packets. After relaying the packet
3832 to the client the notify packet is processed in the server.
3834 * The silc_server_free_client_data now checks whether there is
3835 pending outgoing traffic for the client and purges the data to
3836 the network before removing the client entry.
3838 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3841 an client is killed from the SILC Network. Updated the protocol
3844 Added new function silc_server_send_notify_killed to the
3845 silcd/packet_send.[ch].
3847 * Added function silc_server_packet_relay_notify to relay notify
3848 packets that are destined directly to a client. In this case
3849 the server does not process the notify packets but merely relays
3850 it to the client. Affected file silcd/packet_send.[ch].
3852 Added also silc_server_packet_process_relay_notify to check
3853 whereto relay the notify. Affected file is
3854 silcd/packet_receive.[ch].
3856 * Implemented the KILL command to the server.
3860 * Added the backup schema desgined last fall to the protocol
3861 specs for everyone to see. The specification is in the
3862 *-spec-xx.txt draft and the packet type definitions for the
3863 backup routers is in *-pp-xx.txt draft. Thusly, added also
3864 new packet type SILC_PACKET_CELL_ROUTERS.
3866 * A big security problem in the implementation discovered. The
3867 signoff of an client did not cause new channel key generation
3868 which it of course should've done. The channel keys must be
3869 always re-generated when client leaves (or signoffs) the channel.
3870 The silc_server_remove_from_channels funtion now handles
3871 the channel key re-generation.
3873 * Added `sender' argument to the silc_server_send_notify_on_channels
3874 to not to send the client provided as argument. Affected file
3875 silcd/packet_send.[ch].
3877 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Implemented OPER and SILCOPER commands into the server and
3882 * Added silc_auth_verify and silc_auth_verify_data to verify
3883 the authentication directly from the authentication payload.
3884 It supports verifying both passphrase and public key based
3885 authentication. Affected file lib/silccore/silcauth.[ch].
3887 * Added `hash' field to the SilcIDListData structure. It is the
3888 hash negotiated in the SKE protocol. Affected file is
3891 * Slight redesigning of the SilcAuthPayload handling routines.
3892 Do not send SilcPKCS but SilcPublicKey as argument.
3894 * Implemented the public key authentication support to the
3895 serverconfig. The public key is loaded from the provided path
3896 and saved as authentication data to void * pointer. Thus,
3897 changed the unsigned char *auth_data to void *auth_data;
3899 * Fixed SHUTDOWN command to send the reply before the server
3900 is shutdown. :) Affected file silcd/command.c.
3902 * Fixed fatal bug in CONNECT command. The hostname was invalid
3903 memory and server crashed. Affected file silcd/command.c.
3905 * Fixed fatal bug in CLOSE command. The server_entry became
3906 invalid but was referenced later in the command. Affected file
3909 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Fixed fatal bug in failure packet handling. Server ignored
3912 the failure and thus crashed when it came.
3916 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3919 that the command may be executed only once in (about) 2 seconds.
3920 The old SILC_CF_LAG flag is same but allows command bursts up
3921 to five before limiting.
3923 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3924 server code. Various commands now includes the CF_LAG_STRICT
3925 flag to disallow any kind of miss-use of the command.
3927 * Fixed the silc_buffer_unformat to not to allocate any data
3928 if the length of the data is zero. It used to allocate the
3929 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3931 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Changed the format of AdminConnection configuration section
3934 in the server. Added username of the admin to the format.
3935 Affected files silcd/serverconfig.[ch].
3937 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3938 to return admin configuration data by host, username and/or
3941 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Implemented WHOWAS command to the server. Added the functions:
3945 silc_server_command_whowas_parse,
3946 silc_server_command_whowas_send_reply,
3947 silc_server_command_whowas_from_client and
3948 silc_server_command_whowas_from_server
3950 * Added <Client ID> argument to the WHOWAS command reply. Updated
3951 the protocol specs accordingly.
3953 * Implemented WHOWAS command and command_reply to the client
3956 Implemented the WHOWAS printing on the user interface.
3958 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Added new argument to the WHOWAS command reply, the real name.
3961 It is an optional argument. Updated the protocol specs.
3963 * Added SilcIDCacheDestructor callback that is registered when
3964 the SilcIDCache is allocated. The callback is called when
3965 an cache entry in the ID Cache expires, or is purged from the
3966 cache. Added into lib/silccore/idcache.[ch].
3968 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3969 to destruct the client entries when the cache entry expires.
3970 Other ID Cache's in server and in the client library ignores
3973 * If the ID Cache entry's `expire' field is zero then the entry
3974 never expires. Added boolean `expire' argument to the
3975 silc_idcache_add function in the lib/silccore/idcache.[ch].
3976 If it is TRUE the default expiry value is used.
3978 * Added silc_server_free_client_data_timeout that is registered
3979 when client disconnects. By default for 5 minutes we preserve
3980 the client entry for history - for WHOWAS command.
3982 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Added support to the server to enforce that commands are not
3985 executed more than once in 2 seconds. If server receives
3986 commands from client more frequently, timeout is registered
3987 to process the commands. Affected file silcd/command.c.
3988 Added new function silc_server_command_process_timeout.
3990 * Changed NICK_NOTIFY handling in client library to check that
3991 if the client's nickname was changed, so there is no need to
3992 resolve anything from the server.
3994 * Removed error printing from the WHOIS and IDENTIFY commands.
3995 If error occurs then it is ignored silently in the client library.
3996 The application, however, may map the received error to
3997 human readable error string. The application currently maps
3998 the NO_SUCH_NICKNAME error to string.
4000 * Made the command status message public to the application. Moved
4001 them from lib/silcclient/command_reply.c to
4002 lib/silcclient/command_reply.h. The application can map the
4003 received command status to the string with the
4004 silc_client_command_status_message function.
4006 * Added check to the server to check that client's ID is same
4007 as the Source ID in the packet the client sent. They must
4010 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Added dist-bzip hook to the Makefile.am to make bzip2
4013 compressed distributions.
4015 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Server now enforces the maximum length for the nickname and
4018 the channel as protocol specification dictates. 128 bytes for
4019 nickname and 256 bytes for channel name.
4021 * Moved the WHOIS printing to the application. The client libary
4022 does not print out the WHOIS information anymore, the application
4023 must do it. Renamed silc_client_command_reply_whois_print to
4024 the silc_client_command_reply_whois_save.
4026 The client's idle time is also sent to the application now, and
4027 the idle is shown on screen.
4029 * Added silc_client_command_reply_identify_save to save the
4030 received IDENTIFY entries.
4032 * Do not check for channel private keys in message sending and
4033 reception if the channel does not have the PRIVKEY mode set.
4034 Affected file lib/silclient/client_channel.c.
4036 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4039 just surfaced after chaning the JOIN procedure.
4041 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added silc_client_get_clients_by_list to get client entries
4044 from Client ID list, that is returned for example by JOIN
4045 and USERS command replies. The application should use this
4046 function for example when JOIN command reply is received to
4047 resolve the clients already on the channel (library does not
4048 do that anymore as USERS command reply is not used in the JOIN
4049 procedure anymore). Affected files lib/silcclient/silcapi.h and
4050 lib/silcclient/idlist.c.
4052 * JOIN command reply and USERS command reply returns now SilcBuffer
4053 pointers instead of unsigned char pointers when returning
4054 the client list and mode list.
4056 * Added <Client ID> argument to the JOIN command reply, mainly
4057 for the server to identify for which client the command was
4058 originally sent. Updated protocol specs accordingly.
4060 * Added SilcDlist private_key pointer to the SilcChannelEntry
4061 in the client to support the channel private keys. Affected
4062 file is lib/silcclient/idlist.h.
4064 * Added SilcChannelPrivateKey argument to the function
4065 silc_client_send_channel_message so that application can choose
4066 to use specific private ke if it wants to. If it is not provided,
4067 the normal channel key is used, unless private keys are set.
4068 In this case the first (key that was added first) is used
4069 as the encryption key.
4071 * Implemented the support for channel private key handling.
4072 Implemented the following functions:
4074 silc_client_add_channel_private_key,
4075 silc_client_del_channel_private_keys,
4076 silc_client_del_channel_private_key,
4077 silc_client_list_channel_private_keys and
4078 silc_client_free_channel_private_keys
4080 Affected file lib/silcclient/client_channel.c.
4082 * Added the support for the private keys in the channel message
4083 sending and encryption and in the message reception and
4084 decryption. Affected funtions are
4085 silc_client_send_channel_message and silc_client_channel_message.
4087 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Added SKE's key verify callback to the client library's
4090 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4092 * Removed the statement that server (or router) must send USERS
4093 command reply when joining to the channel so that the client
4094 knows who are on the channel. Instead, the client list and
4095 client's mode list is now sent in the JOIN command reply to the
4096 client who joined channel. This is better solution.
4098 * Added function silc_server_get_users_on_channel and function
4099 silc_server_save_users_on_channel to the silcd/server.[ch].
4101 * Removed function silc_server_command_send_users from the
4104 * Do not show topic on the client library anymore. The topic is
4105 sent in the command reply notify to the application and the
4106 application must show the topic now.
4108 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Added client searching by nickname hash into the IDENTIFY and
4111 WHOIS commands in the server as they were clearly missing from
4112 them. Affected file is silcd/command.c.
4114 * Fixed a bug in private message receiving in the client library.
4115 The remote ID was freed and it wasn't supposed, now it is
4118 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Minor fix to the channel payload; allocate the data area, as it
4121 needs to be of specific length.
4123 * If the key agreement port is zero then the operating
4124 system will define the bound port. Affected files are
4125 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4127 * Added new function silc_channel_payload_decrypt into the file
4128 lib/silccore/silcchannel.[ch].
4130 * Moved the channel message etc, check from silc_packet_decrypt
4131 to applications. The library calls now a generic
4132 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4133 when the packet is either normal or special. This was done to
4134 allow more wide range of checking that was not allowed when
4135 the code was in library. Now applications can do virtually any
4136 checks to the packet and return to the library the decision how
4137 the packet should be processed. Affected files are
4138 lib/silccore/silcpacket.[ch].
4140 Added silc_server_packet_decrypt_check to the server and
4141 silc_client_packet_decrypt_check to the client library.
4143 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4144 to send with specified source and destination information.
4146 * Channel message delivery between routers was broken after the
4147 channel key distribution was fixed earlier. The channel key
4148 was used be to distributed to other routers as well which is not
4149 allowed by the protocol. Now this is fixed and channel keys
4150 really are cell specific and the channel message delivery between
4151 routers comply with the protocol specification.
4153 * Fixed various commands in server to check also the global list
4154 for the channel entry and not just the local list. The affected
4155 file silcd/command.c.
4157 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Added assert()s to buffer formatting and unformatting routines
4160 to assert (if --enable-debug) when error occurs. Affected
4161 file: lib/silcutil/silcbuffmt.c.
4163 * Changed to auto-reconnect to check whether the remote host is
4164 router and register the re-connect timeout if it is. It used
4165 to check that whether we are normal server, but router must do
4166 auto-reconnect with another router as well. Affected file
4169 * Removed the [<key len>] option from CMODE command as the cipher
4170 name decides the key length, nowadays. See the defined ciphers
4171 from the protocol specification.
4173 * Added [<hmac>] option to the CMODE command to define the HMAC
4174 for the channel. Added SILC_CMODE_HMAC channel mode.
4176 * Added [<hmac>] option for the JOIN command so that user can
4177 select which HMAC is used to compute the MACs of the channel
4180 * Added Hmac field to the Channel Message Payload. The integrity
4181 of plaintext channel messages are now protected by computing
4182 MAC of the message and attaching the MAC to the payload. The
4183 MAC is encrypted. Now, it is clear that this causes some
4184 overhead to the size of the packet but rationale for this is that
4185 now the receiver can verify whether the channel message decrypted
4186 correctly and also when private keys are set for the channel the
4187 receiver can decrypt the packet with several keys and check from
4188 the MAC which key decrypted the message correctly.
4190 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4191 lib/silccrypt/silccipher.[ch].
4193 * Added silc_hash_len to return the digest length into the
4194 lib/silcrypt/silchash.[ch].
4196 * Rewrote parts of Silc Channel Payload interface in the
4197 lib/silccore/silcchannel.[ch]. The encode function now also
4198 encrypts the packet and parse function decrypts it.
4200 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Fixed a minor formatting bug in the SKE's key material processing.
4203 It actually might have processed the keys wrong way resulting
4206 * Redefined the mandatory HMAC algorithms and added new algorithms.
4207 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4208 and hmac-md5 truncated to 96 bits. The mandatory is now
4209 hmac-sha1-96. Rest are optional (including the one that used
4210 to be mandatory). Rationale for this is that the truncated HMAC
4211 length is sufficient from security point of view and can actually
4212 make the attack against the HMAC harder. Also, the truncated
4213 HMAC causes less overhead to the packets. See the RFC2104 for
4216 * Added new [hmac] configuration section. The SKE used to use
4217 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4218 is of course wrong. The official names that must be proposed in
4219 the SKE are the ones defined in the protocol specification
4220 (hmac-sha1-96 for example). The user can configure any hmac
4221 using any hash function configured in the [hash] section. At
4222 least, the mandatory must be configured.
4224 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4226 * Added HMAC list to the SKE proposal list. It has now both
4227 hash algorithm list and HMAC list. This makes the protocol
4228 incompatible with previous versions. The SKE now seems to work
4229 the way it is supposed to work, for the first time actually.
4231 * Defined plain Hash algorithms to the protocol specification.
4234 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Implemented support for key agreement packets into the server.
4237 Added functions silc_server_key_agreement and
4238 silc_server_send_key_agreement. Other than these functions,
4239 server has nothing to do with this packet.
4241 * Added support for private message key packets into the server.
4242 Added functions silc_server_private_message_key and
4243 silc_server_send_private_message_key.
4247 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4248 called in the protocol's final callback instead in the END
4249 protocol state. This makes a little more sense and in the same
4250 time in client we can use the same protocol routines for normal
4251 key exchange and to key agreement packet handling as well.
4253 * Added to both client's and server's KE protocol context the
4254 SilcSKEKeyMaterial pointer to save the key material. We will
4255 bring the key material to the protocol's final callback by doing
4256 this. The final callback must free the key material.
4258 * Added SKE's packet_send callback into client's KE protocol
4259 context so that the caller can choose what packet sending function
4260 is used. This way we can use different packet sending when
4261 doing normal SKE when doing key agreement packet handling (in
4262 the key agreement packet handling we do not want to encrypt
4265 * Implemented the responder side of the key agreement routines
4266 in the client. The client can now bind to specified port and
4267 accept incoming key negotiation. The key material is passed
4268 to the application after the protocol is over.
4270 * Implemented the processing of incoming Key Agreement packet
4271 in the client. Added function silc_client_key_agreement to
4274 * Implemented the intiator side of the key agreement routines
4275 in the client. The client can now initiate key agreement with
4276 another remote client. The key material is passed to the
4277 application after the protocol is over.
4279 * Created client_keyagr.c to include all the key agreement
4282 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4283 SILC_TASK_CALLBACK except that it is not static.
4285 * Created client_notify.c and moved the Notify packet handling
4286 from the client.[ch] into that file.
4288 * Created client_prvmsg.c and moved all private message and
4289 private message key routines from the client.[ch] into that file.
4291 * Create client_channel.c and moved all channel message and
4292 channel private key routines from the client.[ch] into that file.
4294 * Changed silc_client_get_client_by_id_resolve to resolve with
4295 WHOIS command instead of IDENTIFY command, in the file
4296 lib/silclient/idlist.c.
4298 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Implemented the SKE's responder side to the Client library.
4302 * When FAILURE is received to the protocol do not trust it
4303 blindly. Register a timeout to wait whether the remote closes
4304 the connection as it should do it, only after that process the
4305 actual failure. This was changed to both client and server.
4307 * Added client_internal.h to include some of the structures
4308 there instead of client.h in lib/silcclient/.
4310 * Added function silc_task_unregister_by_callback to unregister
4311 timeouts by the callback function.
4313 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Some "Incomplete WHOIS info" errors has been appearing on the
4316 log files. Took away the entry->userinfo check from WHOIS
4317 reply sending. The entry->userinfo is now " " if client did not
4318 provide one. I thought this was fixed earlier but something
4319 is wrong still. Let's see if the error still appears.
4321 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Fixed a minor bug in the login when the channel key is
4324 re-generated in the server. It used to generate the key in
4325 wrong order and thus caused problems in the channel traffic.
4327 * Fixed a minor bug in channel key distsribution after
4328 KICK command. The key was not sent to the router even though
4331 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added silc_ske_process_key_material_data as generic routine
4334 to process any key material as the SILC protocol dictates. The
4335 function is used by the actual SKE library but can be used by
4336 applications as well. This relates to the private message keys
4337 and the channel private keys since they must be processed the
4338 same way the normal SILC session keys. The protocol dictates
4339 this. Affected files: lib/silcske/silcske.[ch].
4341 Added also silc_ske_free_key_material to free the
4342 SilcSKEKeyMaterial structure.
4344 * Defined silc_cipher_set_key function to set the key for
4345 cipher without using the object's method function. The affected
4346 files: lib/silccrypt/silccipher.[ch].
4348 * Implemented silc silc_client_add_private_message_key,
4349 silc_client_add_private_message_key_ske,
4350 silc_client_del_private_message_key,
4351 silc_client_list_private_message_keys and
4352 silc_client_free_private_message_keys functions in the
4355 Added functions silc_client_send_private_message_key to send
4356 the Private Message Key payload and silc_client_private_message_key
4357 to handle incoming Private Message Key payload.
4359 * Added Cipher field to the Private Message Key payload to set
4360 the cipher to be used. If ignored, the default cipher defined
4361 in the SILC protocol (aes-256-cbc) is used.
4363 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Removed lib/silcclient/ops.h file.
4367 Redefined parts of the SILC Client Library API. Created new
4368 file silcapi.h that deprecates the ops.h file and defines the
4369 published Client Library API. Defined also private message key
4370 API and channel private key API into the file.
4372 This is the file that the application must include from the
4373 SILC Client Library. Other files need not be included by
4374 the application anymore.
4376 * Added new key_agreement client operation callback and also
4377 defined the Key Agreement library API for the application.
4379 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4382 is used by clients to request key negotiation between another
4383 client in the SILC network. If the negotiation is started it
4384 is performed using the SKE protocol. The result of the
4385 negotiation, the secret key material, can be used for example
4386 as private message key.
4388 Implemented the Key Agreement payload into the files
4389 lib/silccore/silauth.[ch].
4391 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Redefined ciphers for the SILC protocol. Added some new ciphers
4394 and defined the key lengths for the algorithms. Changed the
4395 code accordingly. The default key length is now 256 bits.
4397 * Fixed SKE key distribution function silc_ske_process_key_material
4398 when the key length is more than 128 bits. The default key
4399 length in SILC is now 256 bits.
4401 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4402 to indicate unsupported algorithm.
4404 * Renamed rijndael.c to aes.c and all functions as well.
4406 * Fixed a long standing channel key setting bug in client library.
4407 Weird that it has never surfaced before.
4409 * Fixed bug in channel deletion. If the entire channel is removed
4410 then it must also delete the references of the channel entry
4411 from the client's channel list as the client's channel entry and
4412 the channel's client entry share same memory.
4414 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Implemented CONNECT and SHUTDOWN commands in the client.
4418 * Implemented CLOSE command to the client.
4420 * Added the function silc_idlist_find_server_by_name into the
4421 files silcd/idlist.[ch].
4423 Added the function silc_idlist_find_server_by_conn into the
4424 files silcd/idlist.[ch].
4426 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * DIE command was renamed to SHUTDOWN. Updated the both code
4431 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4432 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4434 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4437 * Added function silc_server_create_connection function to create
4438 connection to remote router. My server implementation actually
4439 does not allow router to connect to normal server (it expects
4440 that normal server always initiates the connection to the router)
4441 so the CONNECT command is only good for connecting to another
4444 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4447 or some other client was kicked from the channel.
4449 Implemented the handling of the notify type to both client
4452 Implemented silc_server_send_notify_kicked to send the KICKED
4453 notify. It is used to send it to the server's primary router.
4455 * Implemented the KICK command into server and client.
4457 * Added `query' argument to the silc_idlist_get_client function
4458 to indicate whether to query the client from server or not if
4461 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4462 to indicate that the client is not channel founder.
4466 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Removed the rng context from SilcPacketContext structure and
4469 changed that the packet routine uses the Global RNG API.
4471 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added support for quit message that client can "leave" on the
4474 channel when it quits the SILC. It is ditributed inside the
4475 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4477 Added silc_server_free_client_data that will take the
4478 signoff message as argument.
4480 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4482 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Updated parts of the protocol specification to keep it up
4487 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4490 payloads in one packet.
4492 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4493 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4494 use now the new List flag.
4496 * Also deprecated the following packet types: REPLACE_ID,
4497 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4499 * Added list support for Notify packet in server.
4501 * Added silc_server_send_notify_channel_change to send the
4502 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4503 the silc_server_send_replace_id.
4505 * Added silc_server_send_notify_nick_change to send the
4506 NICK_CHANGE notify type. Deprecates the function
4507 silc_server_send_replace_id.
4509 * Added silc_server_send_notify_join to send the JOIN notify type.
4510 Deprecates the function silc_server_send_new_channel_user.
4512 * Added silc_server_send_notify_leave to send LEAVE notify type.
4513 Deprecates the function silc_server_send_remove_channel_user.
4515 * Added silc_server_send_notify_cmode and
4516 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4517 types. Deprecates the silc_server_send_set_mode function.
4519 * Added SERVER_SIGNOFF notify type to indicate that server has
4520 quit. This means that all clients on the channel from that
4521 server will drop. This can be also used when netsplit happens.
4523 Deprecated REMOVE_ID packet type since it is not needed anymore
4526 Added silc_server_send_notify_server_signoff to send the
4527 SERVER_SIGNOFF notify type. Deprecates the function
4528 silc_server_send_remove_id.
4530 Added also silc_server_send_notify_signoff to send the
4531 SIGNOFF notify type.
4533 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4534 SILC protocol from this day on. Changed the protocol
4535 specification as well.
4537 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4538 notify type. It is used between routers to notify about
4539 topic changes on a channel.
4541 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4544 * Partly updated the protocol specification to comply with the
4545 changes now made. It is still though a bit outdated.
4547 * The JOIN notify type now takes one extra argument <Channel ID>.
4548 The packet used to be destined to the channel but now the
4549 JOIN type may be sent as list thus it is impossible to
4550 destine it to any specific channel. By adding this argument
4551 it is again possible.
4553 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added CREDITS file. The CHANGES and CREDITS file will appear
4556 in the distribution as well.
4558 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4561 types in the server's silcd/packet_receive.c.
4563 * Implemented CMODE and CUMODE to work in router environment.
4565 * Fixed minor encoding and decoding buglet from the
4566 lib/silccore/silcmode.c.
4568 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4571 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4573 * Changed all SilcConfigServer* and silc_config_server* to
4574 SilcServerConfig* and silc_server_config*, respectively.
4577 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Associated the ID (client or server ID) to the Authentication
4580 Payload to avoid any possibility of forging. Updated the
4581 protocol specification and the code accordingly.
4583 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * The RSA key length is now save to the RsaKey context in the
4586 key generation process in lib/silccrypt/rsa.c. The key length
4587 is now used to figure out the maximum size of the block allowed
4588 to be encrypted/signed.
4590 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4591 is equivalent to the silc_mp_mp2bin but does not allocate any
4594 * Changed silc_mp_mp2bin API to take length argument. If it is
4595 non-zero then the buffer is allocated that large. If zero, then
4596 the size is approximated using silc_mp_sizeinbase, which however
4599 * Created Global RNG API which is global RNG that application can
4600 initialize. After initializing, any routine anywhere in the
4601 code (including library) can use RNG without allocating a new
4602 RNG object. This was done to allow this sort of use of the
4603 RNG in code that has no chance to allocate RNG object. All
4604 applications currently allocate this and many routines in the
4605 library use this. Affected file lib/silccrypt/silcrng.[ch].
4607 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4608 it to use the Global RNG API.
4610 * Defined Authentication Payload into protocol specification that
4611 is used during SILC session to authenticate entities. It is
4612 used for example by client to authenticate itself to the server
4613 to obtain server operator privileges.
4615 Implemented this payload into the lib/silccore/silcauth.[ch].
4616 Implemented also routines for public key based authentication
4617 as the new protocol specification dictates.
4619 Moved definitions of different authentication methods from
4620 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4622 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4623 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4624 silc_pkcs_verify_with_hash functions into the file
4625 lib/silccrypt/silcpkcs.[ch].
4627 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * The client entry's userinfo pointer must be always valid.
4630 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4631 will fail since it requires the userinfo. Now, the userinfo
4632 is allocated as "" if actual userinfo does not exist. Actually,
4633 it must exist and it is totally Ok to drop client connections
4634 that does not announce the userinfo. However, we will make
4635 this workaround for now.
4637 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4638 to return the remote port by socket.
4640 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4643 SILC_SERVER_PENDING_EXEC and added an new macro
4644 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4645 data or when error occurs while processing the pending command.
4647 Added new argument `destructor' into silc_server_command_pending
4648 and to the SilcServerCommandPending object. This destructor is
4649 now called after calling the pending callback or if error occurs
4650 immediately. If error occurs the actual pending callback won't
4651 be called at all - only the destructor. The destructor may be
4652 NULL if destructor is not needed.
4654 All this applies for client library code as well. Similar
4655 changes were made there as well for the pending commands.
4657 In the client, the application must now allocate the
4658 SilcClientCommandContext with the silc_client_command_alloc
4661 * Added reference counter to the SilcServerCommandContext. Added
4662 function silc_server_command_alloc and silc_server_command_dup
4665 Same type of functions added to the client library for the same
4668 * Removed the cmd_ident from IDListData away since it is now
4669 global for all connections. It is the command identifier used
4670 in command sending and with pending commands. The affected file
4673 * Added reference counter to the SilcSocketConnection objecet to
4674 indicate the usage count of the object. The object won't be
4675 freed untill the reference counter hits zero. Currently only
4676 server uses this, and client ignores it. The client must be
4677 set to use this too later. The affected files are
4678 lib/silccore/silcsockconn.[ch]. Added also the function
4679 silc_socket_dup to increase the reference counter.
4681 This was mainly added because it is possible that the socket
4682 is removed underneath of pending command or other async
4683 operation. Now it won't be free'd and proper DISCONNECTING
4684 flags, etc. can be set to avoid sending data to connection that
4685 is not valid anymore.
4687 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4688 the connection. After that it sets SILC_SET_DISCONNECTED.
4689 It is, however, possible that the socket data is not still freed.
4690 The silc_server_packet_process now checks that data is not
4691 read or written to connection that is DISCONNECTED. The socket
4692 get's freed when the reference counter hits zero.
4694 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Changed the client operation API: channel_message operation's
4697 `sender' is now the client entry of the sender, not the nickname
4698 and the `channel' is the channel entry, not the channel name.
4700 In the private_message operation the `sender' is now also the
4701 client entry of the sender not the nickname.
4703 Affected file is lib/silcclient/ops.h and all applications
4704 using the client operations.
4706 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Moved the calling of ops->connect() from connect_to_server_final
4709 into receive_new_id functin since that is the point when the
4710 client is actually allowed to send traffic to network. The
4711 affected file is lib/silcclient/client.c.
4713 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4716 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4717 (if needs broadcasting) instead of broadcasting the packets one
4718 by one which would make a burst in the network traffic.
4720 * Added `broadcast' argument to the functions in silcd/server.[ch]
4721 silc_server_create_new_channel[_with_id] to indicate whether
4722 to send New Channel packet to primary router.
4724 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Added new function into the silcd/server.[ch] files:
4727 silc_server_create_new_channel_with_id to create new channel with
4728 already existing Channel ID.
4730 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4731 lib/silccore/silcpacket.h. This packet is used t send list of
4732 Set Mode payloads inside one packet. Server uses this to set
4733 the modes for the channels and clients on those channels, that it
4734 announced to the router when it connected to it. The protocol
4735 specification has been updated accordingly.
4737 * The silc_server_new_channel did not handle the packet coming
4738 from normal server as it normally does not send that. However,
4739 when it announces its channels it does send it. Implemented
4740 the support for that.
4742 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4743 into the file lib/silccore/id.h.
4745 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Fixed memory leaks in the functions silc_idlist_del_client,
4748 silc_idlist_del_channel and silc_idlist_del_server in the file
4749 silcd/idlist.c. All of those leaked like a sieve.
4751 * Fixed some small memory leaks in the client's function
4752 silc_client_notify_by_server.
4754 * Added functions into silcd/server.c: silc_server_announce_clients,
4755 silc_server_announce_channels and silc_server_announce_server.
4756 These functions are used by normal and router server to announce
4757 to its primary router about clients, channels and servers (when
4758 router) that we own. This is done after we've connected to the
4761 These functions effectively implements the following packet types:
4762 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4763 and SILC_PACKET_NEW_ID_LIST.
4765 * Added new functions into the silcd/packet_receive.[ch]:
4766 silc_server_new_id_list, silc_server_new_channel_list and
4767 silc_server_new_channel_user_list to handle the incoming
4768 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4770 * Added support of changing Channel ID in the function
4771 silc_server_replace_id. If the server that announces a channel
4772 to the router already exists in the router (with same name but
4773 with different Channel ID), router is responsible to send
4774 Replace ID packet to the server and force the server to change
4775 the Channel ID to the one router has.
4777 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4778 client that the Channel ID has been changed by the router. The
4779 normal server sends this to the client. Client must start using
4780 the new Channel ID as the channel's ID.
4782 Implemented handling of this new type into lib/silcclient/client.c
4783 into the function silc_client_notify_by_server.
4785 * Added new function silc_idlist_replace_channel_id into the files
4786 silcd/idlist.[ch] to replace the Channel ID.
4788 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Call silc_server_command_identify_check always when processing
4791 the IDENTIFY command in silcd/command.c
4793 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4796 send keepalive packets. The packet can be sent by clients,
4797 servers and routers.
4799 Added function silc_socket_set_heartbeat into the file
4800 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4801 If not set, the heartbeat is not performed. The actual
4802 heartbeat is implemented in the low level socket connection
4803 library. However, application is responsible of actually
4806 Added silc_server_send_heartbeat to send the actual heartbeat
4807 packet into silcd/packet_send.[ch]. Server now performs
4808 keepalive with all connections.
4810 * Added silc_task_get_first function into lib/silcutil/silctask.c
4811 to return the timeout task with shortest timeout. There was a bug
4812 in task unregistration that caused problems. TODO has been
4813 updated to include that task system must be rewritten.
4815 * The client library will now resolve the client information when
4816 receiving JOIN notify from server for client that we know but
4817 have incomplete information.
4819 * Rewrote parts of silc_server_remove_from_channels and
4820 silc_server_remove_from_one_channel as they did not remove the
4821 channel in some circumstances even though they should've.
4823 * Encryption problem encountered in server:
4825 The LEAVE command used to send the Channel Key packet to the
4826 router immediately after generating it. However, the code
4827 had earlier sent Remove Channel user packet but not immediately,
4828 ie. it was put to queue. The order of packets in the router
4829 was that Channel Key packet was first and Remove Channel User
4830 packet was second, even though they were encrypted in the
4831 reverse order. For this reason, MAC check failed. Now, this
4832 is fixed by not sending the Channel Key packet immediately but
4833 putting it to queue. However, this is more fundamental problem:
4834 packets that are in queue should actually not be encrypted
4835 because packets that are sent immediately gets encrypted
4836 actually with wrong IV (and thus MAC check fails). So, packets
4837 that are in queue should be encrypted when they are sent to
4838 the wire and not when they put to the queue.
4840 However, the problem is that the current system has not been
4841 designed to work that way. Instead, the packet is encrypted
4842 as soon as possible and left to the queue. The queue is then
4843 just purged into wire. There won't be any fixes for this
4844 any time soon. So, the current semantic for packet sending
4847 o If you send packet to remote host and do not force the send
4848 (the packet will be in queue) then all subsequent packets to the
4849 same remote host must also be put to the queue. Only after the
4850 queue has been purged is it safe again to force the packet
4853 o If you send all packets immediately then it safe to send
4854 any of subsequent packets through the queue, however, after
4855 the first packet is put to queue then any subsequent packets
4856 must also be put to the queue.
4858 Follow these rules and everything works fine.
4860 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Added new function silc_server_remove_clients_by_server to
4863 remove all client entries from ID list when the server connection
4864 is lost. In this case it is also important to invalidate all
4865 client entires as they hold the invalid server entry. This
4866 fixes fatal bug when server has lost connection and will reconnect
4869 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Made some sanity checks to silc_server_daemonise like to check
4872 whether the requested user and group actually exists.
4874 * Added sanity check to SKE's silc_ske_responder_finish to check
4875 that the public and private key actually is valid.
4877 * Invalidate the client's nickname when receiving Replace ID
4878 packet and the Client ID is being replaced. This means that the
4879 server will query the nickname if someone needs it (client)
4882 * Sort the ID Cache in client library when the ID Cache data
4883 has changed (needs sorting).
4885 * Do not allow for SILC client to create several connections to
4886 several servers. The client does not support windows right now
4887 and generating multiple connections causes weird behaviour.
4889 Irssi-silc client does support windows and can handle several
4890 connections without problems, see: www.irssi.org and SILC plugin.
4892 * Fixed some places where client was added to the IDList. The
4893 rule of thumb is following (in order to get everything right):
4894 If the client is directly connected local client then the
4895 `connection' argument must be set and `router' argument must be
4896 NULL to silc_idlist_add_client function. If the client is not
4897 directly connected client then the `router' argument must
4898 bet set and the `connection' argument must be NULL to the
4899 silc_idlist_add_client function.
4901 * The funtion silc_server_packet_send_local_channel actually did
4902 not check whether the client was locally connected or not. It
4903 does that now. Fixed a bug related to LEAVE command.
4905 * Fixed Remove Channel User payload parsing bug in server's
4906 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4908 * The server's silc_server_save_channel_key now checks also the
4909 global ID list for the channel as it might not be in the local
4910 list. Fixed a bug related to LEAVE command.
4912 * Is this the end of the [<unknown>] buglet that has been lurking
4913 around for a long time? A little for loop fix in server's
4914 silc_server_command_whois_parse that is used by both IDENTIFY
4915 and WHOIS command. At least, this was a clear bug and a cause
4916 of one type of [<unknown>] buglet.
4918 * WHOIS and IDENTIFY commands call the function
4919 silc_server_command_[whois/identify]_check function even if
4920 we are not router server.
4922 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Added --with-gmp configuration option. If set the GMP
4925 is always compiled in the SILC source tree. If not set then
4926 it is checked whether the system has the GMP3 installed. If
4927 it has then the GMP won't be compiled (the system's headers
4928 and library is used), if it doesn't have it then the GMP is
4929 compiled in the SILC source tree.
4931 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Changed RSA private exponent generation to what PKCS #1
4934 suggests. We try to find the smallest possible d by doing
4935 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4936 not security fix but optimization.
4938 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Added new config entry [Identity] to fork the server and run
4941 it as specific user and group. A patch from Bostik.
4943 * Imported Dotconf configuration library into lib/dotconf.
4944 This will be used to create the SILC configuration files later.
4945 It will appear in the distsribution after this commit.
4947 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * A big code auditing weekend happening. Auditing code for
4950 obvious mistakes, bugs and errors. Also, removing any code
4953 Removed files for being obsolete:
4955 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4956 inline in the file lib/silcutil/silcbuffer.h)
4958 o lib/silcutil/silcbufutil.c (the header has inline versions)
4960 Changed code to fix possible error conditions:
4962 o The buffer formatting routines now check that the destination
4963 buffer really has enough space to add the data. This applies for
4964 both buffer formatting and unformatting
4965 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4966 unformatting was changed to accomodate following rules:
4967 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4968 sent to the function while XXX_*STRING will not allocate or copy
4969 the data into the buffer. Instead it sets the pointer from the
4970 buffer into the pointer sent as argument (XXX_*STRING used to
4971 require that the pointer must be allocated already). This change
4972 makes this whole thing a bit more consistent and more optimized
4973 (note that the data returned in the unformatting with XXX_*STRING
4974 must not be freed now). The routines return now -1 on error.
4976 o Tried to find all code that use buffer_format and buffer_unformat
4977 and added return value checking to prevent formatting and
4978 especially unformatting errors and possible subsequent fatal
4981 o Changed ske->x and ske->KEY to mallocated pointers in
4982 lib/silcske/silcske.h. Fixed possible data and memory leak.
4984 o Added return value checking to all *_parse* functions. Fixed
4985 many memory leaks as well.
4987 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4988 so that buffer overflows would not happen. All code now also
4989 checks the return value as it can fail.
4991 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Added reconnection support to server if the normal server looses
4994 its connection to the router (for example if router is rebooted).
4995 The server performs normal reconnection strategy implemented
4996 to the server. Affected file silcd/server.c.
4998 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Added new packet type SILC_PACKET_SET_MODE that is used to
5001 distribute the information about changed modes (for clients,
5002 channels and clients channel modes) to all routers in the
5003 network. Updated the protocol specification accordingly.
5005 Added functions into silcd/packet_send.c and
5006 silcd/packet_receive.c: silc_server_send_set_mode,
5007 silc_server_set_mode.
5009 Added new files silcmode.[ch] into lib/silccore that implements
5010 the encoding and decoding of Set Mode Payload. Added new type
5011 SilcSetModePayload. Moved the definitions of different modes
5012 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5014 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Oops, a little mistake in server's connection authentication
5017 protocol. The protocol is not ended with FAILURE but with
5018 SUCCESS if the authentication is Ok. :) Affected file is
5021 * Implemented NICK_CHANGE notify handling in server in the file
5022 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5023 the local clients on the channel. After the changing nickname
5024 in router environment snhould work and the [<unknown>] nickname
5025 should appear no more.
5027 The silc_server_replace_id function that receives the Replace ID
5028 payload now sends the NICK_CHANGE notify type also in the file
5029 silcd/packet_receive.c
5031 * Changed WHOIS and IDENTIFY command to support the maximum amount
5032 of arguments defined in protocol specs (3328 arguments). This
5033 fixed a bug that caused problems when there were more than three
5036 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added extra parameter, command identifier, to the
5039 silc_client_send_command so that explicit command identifier
5042 Changed that ID list routines uses specific command identifier
5043 when sending WHOIS/IDENTIFY requests to the server so that they
5044 can be identified when the reply comes back.
5046 Affected files lib/silcclient/command.[ch],
5047 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5049 * Added `sender' argument to silc_server_packet_send_to_channel
5050 to indicaet the sender who originally sent the packet to us
5051 that we are now re-sending. Ignored if NULL. Affected file
5052 silcd/packet_send.[ch].
5054 * Added some server statistics support in silcd/server_internal.h
5055 SilcServerStatistics structure and around the server code. Also
5056 send some nice statistics information when client is connecting
5059 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Fixed channel ID decoding in server's JOIN command reply in
5062 silcd/command_reply.c
5064 * Fixed braodcasting of replace ID payload to not to send it if
5065 we are standalone server in silcd/packet_receive.c.
5067 * Fixed all channel message sending routines to not to send
5068 packets to clients that has router set, since they are routed
5069 separately in the same function earlier. Affects file
5070 silcd/packet_send.c and all channel packet sending functions.
5072 * In USERS reply, res_argv[i] are not allocated, the table
5073 is allocated. Thus changed that free the table, not its
5076 * In server's whois_check and identify_check if the client is
5077 locally connected do not send any WHOIS commands - they are not
5080 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Fixed some minor bugs in client when sending WHOIS command. The
5083 arguments was in wrong order.
5085 * Removed statis function add_to_channel from server in
5086 silcd/command.c that was previously used with the joining but
5089 * Tested USERS command in router environment successfully with two
5090 routers, two servers and two clients.
5092 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Reorganized the USERS command and command reply in client library
5095 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5096 When the command is given by user we register a pending command
5097 callback that will reprocess the command after the reply has been
5098 received from the server. When reprocessing the packet we then
5099 display the information. Thus, the USERS information is displayed
5100 now in the command callback instead of in the command reply
5101 callback. The processing of the command is same as previously
5102 when server has sent the command reply in the JOINing process.
5104 * Added to USERS command in silcd/command_reply.c to join the client,
5105 we didn't use to know about, to the channel after we've created
5106 a client entry for it. Also, for clienet we did know already still
5107 check whether it is on the channel or not and add it if not.
5109 * Removed silc_server_command_join_notify as the function and its
5112 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Changed the client's pending command handling to the same as the
5115 server's pending command handling. It is also now possible to
5116 execute command reply functions from other command reply
5117 function as the function callbacks for commands and command
5118 replies are one and same. The pending commands are not static
5119 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5120 in client connection context. Thus, pending commands are server
5121 connection specific as it is convenient.
5123 Changed the function silc_client_command_pending and
5124 silc_client_command_pending_del and added new function
5125 silc_client_command_pending_check. Removed the
5126 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5129 * Added cmd_ident, current command identifier, to the client
5130 connection context in lib/silcclient/client.h to keep track on
5131 command identifiers used in command sending. Client's command reply
5132 function handling now supports the mandatory command identifiers.
5134 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5135 funtions in client to fully support pending command callbacks.
5137 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5138 as one of the arguments to the application in the command reply
5141 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5142 before first releasing SILC but came back. Now it is removed again
5143 and should come back nomore. The FORWARDED flag was used only
5144 by the JOINing procedure by forwarding the command packet to router.
5145 Now, the JOINing procedure has been changed to more generic (due
5146 to various router environment issues) and FORWARDED is not needed
5147 anymore for anything. The protocol specification is yet to be
5150 Now, removed silc_server_packet_forward from server and the flag
5151 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5153 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Renamed NAMES command to USERS command. The NAMES was named that
5156 due to historical reasons. Now it is renamed. Also, rewrote
5157 parts of the USERS command. The nickname list is not sent anymore
5158 by the server. Only Client ID and mode lists are sent in the USERS
5159 command. Changed this also to the protocol specification.
5161 The client now resolves the names and stuff after it receives
5162 the USERS list from the server when joining to the channel.
5164 * WHOIS and IDENTIFY commands has been changed to support multiple
5165 Client ID's per command. One can now search for multiple users
5166 in the network by sending only one WHOIS or IDENTIFY command.
5167 Changed the code and the protocol specifications.
5169 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5170 uses silc_server_command_whois_parse to parse the request. */
5172 * If normal server, do not parse the WHOIS and IDENTIFY requests
5173 before sending it to the router. Saves some time.
5175 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Fixed JOIN command on client library. Wrong number of arguments
5178 used to crash the client.
5180 * Added silc_server_channel_has_global function to check whether
5181 channel has global users or not.
5183 * Added silc_server_channel_has_local function to check whether channel
5184 has locally connected clients on the channel.
5186 * The silc_server_remove_from_one_channel now checks whether the
5187 channel has global users or not after given client was removed from
5188 the channel. It also checks whether the channel has local clients
5189 on the channel anymore. If it does not have then the channel entry
5190 is removed as it is not needed anymore.
5192 * The silc_server_notify now checks on JOIN notify whether the joining
5193 client is one of locally connected or global. If it is global then
5194 the channel has now global users on the channel and that is marked
5195 to the channel entry. Also, it now saves the global client to
5196 global list who is joining and JOINs it to the channel. This is
5197 for normal server, that is.
5199 Changed silc_server_send_notify_on_channel,
5200 silc_server_packet_relay_to_channel and
5201 silc_server_packet_send_to_channel check if we are normal server
5202 and client has router set (ie. global client) do not send the
5203 message to that client, as it is already routed to our router.
5205 * Implemented LEAVE notify type handling in silc_server_notify
5208 * Tested LEAVE command in router environment successfully. Tested
5209 with two routers, two servers and two clients.
5213 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5215 * Implemented SIGNOFF notify type handling in silc_server_notify
5218 * silc_server_remove_id now removes the client entry from all channels
5219 it has joined and thusly sends SIGNOFF notify type.
5221 * Rewrote the NAMES list generation in server by removing two excess
5222 loops. The lists are created now inside one loop.
5224 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * silc_server_remove_channel_user checks now also global list
5227 for channel and client.
5229 * silc_server_new_channel_user checks now both local and global
5230 list for channel and client. Fixed a bug in client id decoding.
5231 Used to decode wrong buffer.
5233 * silc_server_channel_message checks now both local and global
5234 list for channel entry.
5236 * Tested channel joining (hence JOIN) in router environment
5237 successfully. Tested with two routers, two servers and two
5240 * Tested channel message sending in router environment successfully.
5242 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Added silc_server_save_channel_key into server.[ch] to save the
5245 received channel key in Channel Key payload processing. It is
5246 also used in JOIN command reply handling.
5248 Equivalent function silc_client_save_channel_key added into
5249 client.[ch] into client library.
5251 * Changed JOIN command reply to send information whether the channel
5252 was created or not (is existing already) and the channel key
5253 payload. Changed protocol specs accordingly.
5255 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5256 the request was sent by ID and not by nickname. Crashed on
5259 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5262 now correctly save the received data.
5264 * silc_server_free_sock_user_data now notifies routers in the
5265 network about entities leaving the network.
5267 At the same time implemented functions silc_server_remove_id
5268 and silc_server_send_remove_id to receive and send REMOVE_ID
5269 packets. The packet is used to notify routers in the network
5270 about leaving entities. The ID removed will become invalid in
5273 * Added function silc_idlist_del_server into server. Removes and
5274 free's server entry from ID list.
5276 * silc_server_private_message function now checks, if we are router,
5277 that the destination ID really is valid ID, naturally.
5279 * In router when NEW_ID packet is received (for new client) the
5280 hash of the Client ID is saved in the ID Cache but the
5281 client->nickname is set to NULL, instead of putting the hash
5284 IDENTIFY command now also checks that client->nickname must be
5285 valid. If it is not if will request the data from the server who
5286 owns the client. Added new function
5287 silc_server_command_identify_check.
5289 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5290 to set the command to already allocated Command Payload.
5292 * Tested private message sending in router environment with two
5293 routers, two servers and two clients. Fixed minor bugs and now
5296 * Fixed segfault from client's NAMES command. Used to crash if
5299 * Forwarded packets must not be routed even if it is not destined
5300 to the receiver. Changed server code comply with this.
5302 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Added `require_reverse_mapping' boolean value to ServerParams
5305 structure. If TRUE (not default) the server will require that
5306 the connecting host has fully qualified domain name.
5308 If the reverse mapping is not required and hostname could not be
5309 found the IP address is used as hostname.
5311 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Implemented version string checking to both client and server.
5314 The check is incomplete currently due to the abnormal version
5315 strings used in development version of SILC.
5317 * Changed all command functions in server to use the new
5320 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Changed char *data to unsigned char *data in ID Cache system to
5323 support binary data as ID Cache data. Changed code to support
5324 binary data in lib/silccore/idcache.c.
5326 * Renamed silc_server_packet_relay_command_reply to
5327 silc_server_command_reply as it is normal packet receiving
5328 function. Rewrote the function to accept command replys for
5329 servers and not only for clients.
5331 * Mark remote router always as registered server if we are connecting
5332 to it. Otherwise, commands sent by the router to us are ignored.
5334 * All ID List find routines now returns the ID Cache Entry pointer
5335 as well if requested.
5337 * WHOIS command works now in router environment, tested with two
5338 routers, two servers and two clients.
5340 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5341 in router environment (as it is almost equivalent to WHOIS) but
5342 hasn't been tested thoroughly. Added new functions:
5344 silc_server_command_identify_parse
5345 silc_server_command_identify_send_reply
5346 silc_server_command_identify_from_client
5347 silc_server_command_identify_from_server
5349 * Disabled route cache adding because adding two different ID's with
5350 same IP replaces the old cache entry thus giving wrong route.
5351 The entry->router->connection is always the fastest route anyway
5352 so route cache may not be needed. Of course, new routes maybe
5353 established after receiving the ID when the entry->router->connection
5354 might not be anymore the most optimal.
5356 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Add route cache for received ID for fast routing.
5360 * Added silc_server_packet_route to route received packet on router
5361 that is not destined to us.
5363 * Renamed silc_server_get_route to silc_server_route_get.
5365 * Added id_string and id_string_len fields into SilcServer to
5366 include encoded ServerID for fast comparing without excess
5367 encoding of the ID's.
5369 * Cleaned up WHOIS command on server side. Added following static
5372 silc_server_command_whois_parse
5373 silc_server_command_whois_check
5374 silc_server_command_whois_send_reply
5375 silc_server_command_whois_from_client
5376 silc_server_command_whois_from_server
5378 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5379 arguments in command replies. All command functions should be
5380 updated to use this macro.
5382 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Minor typo fixes on command reply handling on server.
5386 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Added silc_server_command_add_to_channel internal routine to add
5389 the client to the channel after router has created the channel and
5390 sent command reply to the server.
5392 * Added generic silc_server_send_command to send any command from
5395 * Use static buffer with ID rendering instead of duplicating data.
5397 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Fixed a channel user mode bug when joining to a channel server gave
5400 everybody channel founder rights, oops.
5402 * We mark ourselves as the router of the incoming server connection
5403 if we are router ourselves. This way we can check in some packet
5404 sending functions whether it is locally connected server. For
5405 incoming router connections we put NULL.
5407 * For router sending packets locally means now always sending the
5408 packet cell wide; to local clients and local servers. For normal
5409 server sending packet locally means sending it to only local
5412 * Fixed the JOIN command to really work in router environment. If the
5413 channel is created it is always created by the router. Router is
5414 also responsible of making the initial joining to the channel,
5415 sending JOIN notify to the sending server and distributing
5416 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5417 does not exist server doesn't do anything else but forward the
5418 command to the router which performs everything.
5420 * Added silc_server_send_channel_key function to send the Channel Key
5423 * Added silc_server_create_channel_key to create new channel key. The
5424 channel key is now re-generated everytime someone joins or leaves
5425 a channel, as protocol dictates. Note: channel->key_len is the
5428 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5431 packet_receive.[ch] to separate packet sending and receiving
5432 routines. The server.[ch] now includes everything else including
5433 actual packet processing (writing and reading data) and other
5436 Renamed silc_server_private_message_send_internal to
5437 silc_server_send_private_message. The routine is still though
5438 used only to relay private messages as server does not send
5439 private messages itself.
5441 Renamed silc_server_new_channel to silc_server_create_new_channel
5442 and added new function sicl_server_new_channel that handles the
5443 incoming New Channel packet. Added also new sending function
5444 silc_server_send_new_channel to send New Channel Payload.
5446 * Added new function silc_server_notify to process incoming notify
5447 packet to the server/router. Server may then relay the notify
5448 to clients if needed.
5450 * Added new function silc_server_new_channel_user to process incoming
5451 New Channel User packet. Router will redistribute the packet and
5452 send JOIN notify to its local clients and locally connected servers
5453 if needed. Normal server will send JOIN notify to its local client
5454 on same channel when received this packet. Added also corresponding
5455 sending function silc_server_send_new_channel_user to sent the
5458 * Added boolean route argument to send_notif_to_channel and
5459 packet_send_to_channel functions to attempt to route the packet
5460 if it is TRUE and send only locally if it is FALSE.
5462 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * silc_server_replace_id now broadcasts the received replace ID
5465 packet if it is not broadcast packet already. The router must
5466 broadcast to inform other routers about changed ID.
5468 * Added backpointer to server's router into SilcServer context in
5469 silcd/server_internal.h.
5471 * Fixed silc_server_packet_broadcast to send correct broadcast
5474 * The channel key is now distributed to the local client as soon
5475 as it is received from the router (in router environment) so that
5476 no other packet may be sent for the channel until client has
5479 * silc_server_remove_channel_user now broadcasts the received
5480 Remove Channel User packet if it is not broadcast packet already.
5481 The router must broadcast to inform other routers about removed
5484 * Added users field into SilcPacketContext that is a reference count
5485 of the context. One can increase the reference count by calling
5486 silc_packet_context_dup which is now changed to just increase the
5487 reference count instead of duplicating the data. The reference
5488 count is decresed by calling silc_packet_context_free that will
5489 free the data after the reference count hits zero.
5491 For now on the packet context and everything allocated into it
5492 (including the raw packet from network) must be freed by calling
5493 the new silc_packet_context_free function. Added also new function
5494 silc_packet_context_alloc that must be used now to allocate the
5495 context. This also means that if a routine is asynchronous from
5496 silc_[client/server]_packet_parse_type the packet context must
5497 be duplicated by calling silc_packet_context_dup. Otherwise it
5498 gets free'd after silc_[client/server]_packet_parse_type returns.
5499 Also, one must remember that if packet is duplicated then its
5500 reference count must be decresed by calling the free function as
5501 many times as it was duplicated.
5503 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5504 from both client and server.
5506 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Made joining to a channel working in router environment.
5510 * Cleaned up JOIN command on server side and create function
5511 silc_server_command_join_channel internal routine to make the
5514 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Changed silc_command_pending list to SilcDList. Also, added
5517 `ident' field to SilcServerCommandPending structure to identify
5518 the reply and to call correct callback.
5520 Added silc_server_command_pending_check function to replace the
5521 corresnponding macro. The silc_command_pending list is not
5524 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5525 to set identifier to previously allocated Command Payload. It
5526 is used to set identifier for command when resending Command
5529 * Added silc_command_payload_encode_payload to encode Command
5530 Payload buffer from SilcCommandPayload structure.
5532 * Added silc_argument_payload_encode_payload to encode Argument
5533 payload buffer from SilcArgumentPayload structure.
5535 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Changed WHOIS command to support router connection on server side.
5538 The whois request is always sent to router unless the server is
5539 standalone server. After server has received the reply from the
5540 router will it send the reply to the client.
5542 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5543 broadcast received broadcast packet. The function is used only
5544 by router. The broadcast packet is always sent to the router's
5547 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5548 render given ID to printable string, for log files for example.
5550 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Made basic router to router connections working. At least they
5553 can now connect to each other but nothing really works the way
5554 they are supposed - yet.
5556 * Added new initiator token to RouterConnection configuration
5557 file in silcd/serverconfig.[ch]. It is used to tell whether we
5558 are the initiator to the remote router or whether we'll expect
5559 the other end to connect.
5561 * Moved registering of listener task to silc_server_init, hence
5562 the server starts listenning as soon as it is run, even if it
5563 does not have connections to other routers. Let's see how well
5566 * Changed default connection retry timeouts for more suitable in
5569 * Removed cipher and such arguments from silc_idlist_add_client
5570 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5571 Added new function silc_idlist_add_data to add the keys and stuff
5574 * Added SilcIDListData structure and added it to SilcClientEntry
5575 and SilcServerEntry as their first field in the structure. This
5576 way we can explicitly cast the ID entries to the SilcIDListData
5577 structure and get common data for the entries. In past, we had
5578 to first check what type of connection it is and then cast it to
5579 correct ID entry type. Now, we can directly cast the opaque
5580 pointer to the SilcIDListData (no matter what ID entry it actually
5581 is) and get the data needed.
5583 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5586 in some circumstances even if threre were timeout tasks, though not
5587 IO tasks, but tasks anyway. Now fixed.
5589 * Defined SilcServerConnection structure to hold connection specific
5590 stuff about directly connected servers and routers. The definition
5591 is currently in silcd/server_internal.h. I thought about having
5592 a bit more important role fro this struct but for now it is used
5593 only when connecting to other server (or router actually).
5595 * Added connecting retry support in server when connecting to
5596 router(s). The retry feature implement exponential backoff
5597 algorithm. Also, added SilcServerParams structure to hold default
5598 parameters for server. For now, it include these retry settings
5599 and are hard coded. After server is moded to be as Silc Server
5600 Library this structure will be more important.
5602 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Changed client librarys channel->clients table to SilcList and
5605 changed code accordingly.
5607 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Changed client's channel table to SilcList and changed code
5610 accordingly. Also changed SilcChannelClientEntry to include back-
5611 pointer to the channel so that client entry can use that structure
5612 as list as well and we have fast cross-reference to the channel.
5613 This change dramatically decreased the complexity of channel
5614 handling with client entry and vice versa (removed one extra
5615 loop when searching for channel entry from many functions).
5617 * Changed server->sim from table to SilcDList and changed code
5620 * NAMES command can now be used from user interface. It will show
5621 the user list on the channel, neatly.
5623 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5624 Code now saves realname of the user if it becomes available.
5626 * Renamed configure.in to configure.in.pre and made ./prepare
5627 script to automatically add correct version string to
5628 configure.in which it creates from configure.in.pre.
5630 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * NAMES command reply now shows users mode with the nickname when
5635 * Moved silc_client_ch[u]mode[_char] functions from
5636 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5637 place sucks, they are utility functions and should be in some
5640 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5642 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5645 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added TRQ (efficient deque and list library) into lib/trq. This is
5650 a very good list library that is currently used in the SILC. Defined
5651 SilcList API over the library because I didn't like the API very
5652 much. See lib/trq/silclist.h for the API and examples of how to
5653 use the API. Fixed various places in the code to use the new
5654 SilcList API. The SilcList is meant for lists that has a structure
5655 already defined as a list. It is not suitable to add just some
5656 context to the list (in TRQ, the context is the list actually).
5658 So, I defined SilcDList that can be used for the purpose where
5659 predefined list structure does not exit. This can be used as
5660 such list. Now some context just can be added to the SilcDList.
5661 Currently this list is not used in the SILC just yet, though there
5662 are a lot places where this can replace dynamically allocated
5663 tables and I will fix these places, later, to use SilcDList.
5664 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5665 and use TRQ internally).
5667 Also fixed some annoying warning messages that the original TRQ
5668 code generated. Also minor changes to TRQ's Makefile.in.
5670 * Added support for querying by Client ID to both WHOIS and
5671 IDENTIFY commands into server, as required by the protocol.
5673 * Removed method function pointers from SilcBuffer structure. They
5674 weren't used to anything and just increased the context size for
5675 no good reason. This change also made silc_buffer_alloc and
5676 silc_buffer_free functions inline functions.
5678 * Disabled command flooding detection support until it's fixed so
5679 that it accepts commands in but does not execute them more than once
5682 * Added silc_net_localhost(), to return local hostname, into
5683 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5684 that must be initialized before calling silc_client_init.
5686 * Added new function: silc_server_send_notify_on_channels to send
5687 notify messages to all channels client has joined. It is assured
5688 that the message is sent only once per client.
5690 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5691 lib/silcutil/silcutil.[ch] as silc_format function. The new
5692 function is generic and is used by server as well, not only by
5693 the logging routines.
5695 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5696 the provided version string was not acceptable. Added new function:
5697 silc_ske_check_version into lib/silcske/silcske.h. The function
5698 must be implemented by the application (client or server) and it
5699 does not reside in the SKE library. The function checks the version
5700 string remote end sent.
5702 * Added back pointers (to opaque context and to SilcSocketConnection)
5703 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5705 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5706 duplicate packet context structure.
5708 * Changed `notify' client operation to send same arguments as client
5709 receives from server except for ID's. ID's are mapped to correct
5710 ID entry and that is returned. Also, if channel entry is not sent
5711 by server but the notify is for channel the channel entry is sent
5712 to application (otherwise application doesn't know that it is for
5713 channel (library gets it from packet's Destination ID)).
5715 * Added silc_client_remove_from_channels into client library to
5716 remove a client from all channels it has joined to. Used when
5717 received SIGNOFF notify from server. Added also new function
5718 silc_client_replace_from_channels to replace old ID entry with
5719 new ID entry on all channels. Used when received NICK_CHANGE
5722 * Fixed ID Cache list handling in silc_idlist_get_client in
5723 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5724 to get (or query) client by ID.
5726 * Updated TODO list.
5728 * Added connection authentication status message defined by the
5729 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5730 support for these into the code in client and server side.
5732 * Added generic function silc_client_send_command to send any command
5733 with variable argument list. Application should use this function
5734 to send commands if the command functions provided by the library
5735 does not suite for the application's user interface needs.
5737 * Added new `failure' client operation. Application is notified about
5738 received failure packet if client is executing a protocol. In this
5739 case the protocol's execution has failed.
5741 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5742 is required by the protocol.
5744 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5745 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5748 * Added status flag to SilcSKE object to indicate realtime status
5749 of the SKE protocol.
5751 * Application receives now exactly same command reply arguments as
5752 the library receives from server. However, if ID is received the
5753 corresponding ID entry is returned to the application (eg. Client
5754 ID is mapped to correct SilcClientEntry entry and that is returned).
5755 Changed command_reply client operation due to this change.
5757 * Changed all ID's in commands and in command replys as ID Payloads.
5758 Change affected both client and server side codes.
5760 All ID's sent in SILC network (with execption of ID's in SILC
5761 Packet header) are sent in ID Payload to support variable length
5764 * Server now notifies nick changes and notifies all clients on
5765 the channels about the new nickname (about the new Client ID,
5768 * Implemented CMODE command to change channel modes. Supports all
5769 channel modes defined by the protocol specs except ban and invite
5770 lists. (Also, private channel key mode is supported but support for
5771 setting private channel key in client is missing, thus, this mode
5772 has no effect on client side (except that server requires that the
5773 client uses private channel key and normal channel traffic does not
5776 Also, invite mode works per se, but INVITE command does not work
5777 yet correctly, so you can set channel as invite only channel but
5778 inviting clients to the channel does not work (it is yet to be
5779 thought what's the best way to do it).
5781 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5782 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5783 Implemented CUMODE command to change user's mode on the channel.
5784 Supports all modes defined by the protocol specs.
5786 * Added NAMES command reply to return users modes on the channel.
5788 * Removed unnecessary and slow ciphers from lib/silccrypt.
5790 * Set SO_KEEPALIVE option to connection sockets by default.
5792 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5794 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5795 redefined the Notify Payload into protocol specs.
5797 * Added silc_id_payload_parse_id to get ID directly from raw
5800 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5803 accept searching by Client ID as well.
5805 * Added support for LEAVE and SIGNOFF notify types in client library.
5807 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5808 to parse ID Payload from raw data.
5810 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Added flags parameter into silc_ske_assemble_security_properties
5813 function in lib/silcske/silcske.[ch].
5815 * Changed notify client operation to fit better for notify messages
5816 sent by server. The notify payload received from server is now
5817 passed to the application (after parsing it to SilcNotifyPayload).
5818 It is application's responsibility to retrieve the arguments
5819 from the payload and show the message the way it wants. The message
5820 sent by server is implementation specific.
5822 * Changed public keys to comply with the protocol specification.
5823 Old public keys are not supported anymore and are not compatible.
5825 * Removed nickname from Channel Payload as the latest draft removed
5826 it. The client must resolve the nickname from the NAMES command
5827 reply received when it joined the channel.
5829 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5831 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Fixed some errors in protocol specification drafts.
5835 * Created lib/silccore/silcnotify.c to implement Notify Payload
5836 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5837 generic payloads described by protocol specifications. The file
5838 includes implementations for ID Payload and Argument Payload.
5840 * Changed Command Payload implementation to use the new Argument
5841 Payload. Changed command_xxxx_payload to command_payload_xxxx
5842 to comply with SILC coding conventions.
5844 * Added suppport for Argument Payload handling in Notify Payload
5845 implementation as protocol requires it. Added the new support
5846 into server and client lib as well.
5848 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Added support for multiple nicknames on same channel. [n] is
5851 added locally to the nickname if there are more than one same
5852 nicknames on the channel.
5854 * Server now sends all nicknames that matched WHOIS request.
5855 Client also shows the list received from server.
5857 * Added TOPIC command to client side. User can now set and show
5858 current topic on channel.
5860 * Added MOTD command to client and server. Also, server sends the
5861 motd when client connects to the server.
5863 * Changed version strings to comply ISO 8601.
5865 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Fixed protocol error handling in client library. It should now
5868 cope even if the SKE fails for some reason.
5870 * Made new protocol specification drafts for submitting to IETF.
5872 * Implemented TOPIC command to server in silcd/command.c.
5874 * Added two new notify types into lib/silccore/silcnotify.h:
5875 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5876 notify nickname change and topic setting/change on a channel.
5878 * API change of command_reply operation in client library. The
5879 application gets now the status type received from server as well.
5881 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5885 * Cras fixed and optimized the packet handling even further and
5886 it should work now. Minor change to the prototype of function
5887 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5889 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added new function into lib/silcutil/silcschedule.[ch]:
5892 silc_schedule_with_fd to select() a specified fd. The function
5893 returns after timeout expires or data arrives or goes. The
5894 function is used by packet routines to wait that all data is
5895 received from network.
5897 * Fixed data reading from network in lib/silccore/silcpacket.c.
5898 The code now assures that all data is read from the fd and then
5899 continues packet processing. This was a bug fix since the code
5900 used to drop some data in some circumstances.
5902 * Added new function into lib/silcclient/client.[ch]:
5903 silc_client_start_key_exchange to start key exchange after
5904 connection has been established to server. The code internally
5905 now uses this funtion but its main purpose was to provide it
5906 for applications that perform their own connecting. After
5907 application has created a connection it merely calls this
5908 function to start the key exchange between client and server.
5909 The library takes care of everything else after that.
5911 Updated also lib/silcclient/README to explain the usage of
5914 * Do not send to application information that connection has
5915 been established. Application gets notified it by connect
5918 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Applied cras's patch to add silc_schedule_one function. The
5921 function runs scheduler once and returns.
5923 * Fixed the scheduler after cras messed it up. The timeout
5924 handling works now as it's supposed to work.
5926 * Added into lib/silccore/ silcnotify.h to include notify
5927 message types support. Changed silc_server_send_notify*
5928 functions, in server.[ch], to support those new notify types.
5929 Added the support for the notify types into client library,
5930 as well. Added new notify client operation into ops.h in
5933 * Changed silc_server_packet_send_to_channel to send normal
5934 packets instead of just channel message packets. The function
5935 is now used to send the notify packets to channels. It is not
5936 used to send channel message packets anymore, as server never
5939 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5940 va_arg()s as it seems to require it nowadays. I guess, if SILC
5941 is compiled with older va_arg() the new code should work anyway.
5943 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Splitted core library. Core library (lib/silccore) includes
5946 now only SILC protocol specific core (and common) components.
5947 Created new utility library (lib/silcutil) that includes more
5948 generic purpose stuff. The stuff for util library was taken
5949 from the old core library. This was minor and easy split.
5951 * Created SILC Client Library (lib/silcclient) that includes
5952 implementation of the SILC client without user interface. This
5953 was major move from silc/ directory. The code has been changed
5954 so that it is transparent towards the user interface. The
5955 silc/ directory includes now the same user interface as before
5956 and it uses the new client library. Read lib/silcclient/README.
5957 Basicly, the client library performs everything else related
5958 to SILC except user interface handling. Also, configuration
5959 files are considered to be part of user interface and library
5960 does not handle them.
5962 This change also changed a lot of structures, function naming etc.
5963 Most important change was that SilcClientWindow object was
5964 renamed to SilcClientConnection in the client library. Created
5965 also new file lib/silcclient/ops.h. Also added new files
5966 silc/local_command.[ch] and silc/client_ops.[ch].
5968 All these changes were made to make it easier for user interface
5969 designers to create what ever user interface for the SILC client
5972 It is also expected that the server will be moved to lib
5973 directory as well and SILC Server Library will be created;
5974 sometimes in the future.
5976 * Removed Local commands from lib/silccore/silccommand.h as
5977 they are application specific and new client library does not
5978 handle any of those anymore.
5980 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5981 old client implementation in silc/.
5983 * Added support for callback functions in SILC_LOG_* macros.
5984 Application can now set its own callbacks that will be called
5985 instead of using the default functions that will always print
5986 the debug messages to stderr (or stdout). Also, debugging can
5987 now be disabled by setting silc_debug to FALSE and re-enabled by
5988 setting it to TRUE. Note, that logging will still work even
5989 if debugging is disabled.
5991 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5992 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5993 silc_log_reset_debug_callbacks.
5995 * To enable debugging in silc client one must give now -d
5996 option on command line.
5998 * Changed silc_schedule_init to automatically allocate task queues
5999 if they are not allocated before calling it.
6001 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Added GMP 3.1 into math library.
6005 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6008 a channel in SILC network. The packet is used by servers and
6009 routers to notify other routers that user has left a channel.
6010 This little feature was missing until now. Added the feature
6011 to protocol specification as well.
6013 Added functions: silc_server_send_remove_channel_user and
6014 silc_server_remove_channel_user into server.[ch].
6016 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6017 lib/silccore/silcpacket.h. However, they are not implemented
6020 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Fixed joining to a channel and sending channel messages
6023 between server and router. The channel message sending should
6024 now work inside a cell.
6026 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Fixed the private message sending between server and router.
6029 The private message sending should now work inside a cell.
6031 * Added silc_server_replace_id into server.[ch] to replace
6032 existing ID in the SILC network.
6034 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6035 and silc_idlist_replace_server_id into idlist.[ch] in server.
6037 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Fixed the server to server connections. Server can again now
6040 connect to router. Router to router connections probably does
6043 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Added dynamic protocol registering support. Now protocols can
6046 registered and unregistered on the fly. Patch by cras.
6048 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Added lib/contrib directory to hold routines that some platforms
6051 don't have but are needed by SILC.
6053 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6054 into lin/contrib to provide getopt() and getopt_long() for
6055 those who don't have it.
6057 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added AWAY command to client. When away message is set and
6060 client receives a private message packet the client automatically
6061 replies to the sender with the away message.
6063 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6064 bug seemed to be the cause of recent problems when compiling
6067 * Added version detection support to SKE protocol specification
6068 and added the new changes to the SKE implementation as well.
6069 There were other minor changes in the SKE protocol as well.
6071 Many changes in lib/silcske/silcske.[ch] and in
6072 lib/silcske/payload.[ch].
6074 * Added ^U functionality, clear input line. Patch from cras.
6076 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Mainly small bugfixes on core library. Fixed some debugging
6079 logging and buffer overflow in silclog.c.
6081 * Updated config.sub and config.guess on the distribution tree.
6083 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added command lagging support in server. Client may execute
6086 commands now only once in two seconds.
6088 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Optimized packet reception. MAC computation and checking is now
6091 also more optimized. A lot previously duplicated code is now
6092 used as generic by both client and server.
6094 * Fixed key pair generation in clientutil.c
6096 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Added into lib/silccore/silcbufutil.[ch] new function;
6099 silc_buffer_realloc.
6101 * Moved generic packet sending/encryption functions to
6102 lib/silccore/silcpacket.[ch] from client and server. Some
6103 rewriting of the functions.
6105 * Moved all generic packet reception/decryption functions to
6106 lib/silccore/silcpacket.[ch] from client and server. The
6107 packet processing is now much cleaner in both client and server.
6108 These were major changes in both client and server.
6110 * Created many common functions in server to do packet sending.
6111 Previously code were duplicated a lot, this has been removed
6114 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Rewrote major parts of the ID cache system. Don't know
6117 whether it is better now or not but at least the API is more
6120 * Major rewrite on ID cache stuff on client because of the ID
6121 cache API changes. Added idlist.c to client.
6123 * Also major rewrite on ID cache stuff on server as well.
6124 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6125 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6126 in hand, instead they are all put into the ID cache system now.
6127 All server_idlist_* routines uses ID cache now instead of
6128 traversing its own lists (those lists does not exist anymore).
6129 SilcIDList though still exists. Also, SilcXXXEntry's are
6132 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Finally made the SKE implementation compliant to the protocol
6135 specification. All mp integers are now binary encoded as
6136 opposed being HEX encoded.
6138 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6141 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6142 functions: silc_[encode/decode]_pem. Also added function
6143 silc_encode_pem_file to PEM encode with newlines ('\n') for
6146 * SILC public keys are now encoded either PEM or binary. Same
6147 option is for private keys as well. By default private keys
6148 are binary encoded and public keys PEM encoded. Silly HEX
6149 encoding were removed.
6151 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6152 function to create fingerprints.
6154 * Fixed a bug in SHA1; does not change the original data anymore.
6156 * Partly implemented INFO command on client and server side.
6157 Fixed CLEAR command. Changes to SERVER command; show current
6158 server(s) when giving command without arguments. Added
6159 VERSION command to client.
6161 * Added check to server that unregistered connections cannot
6162 execute commands (unless it is specificly allowed).
6164 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Fixed screen refresh.
6168 * Fixed channel joining bug from client. On some circumstances
6169 client tried to join to a channel it had already joined.
6171 * Added public key verification process into client's protocol.c.
6172 The client now verifies the public key from user and saves
6173 it into ~./silc/serverkeys/ directory.
6175 Added into: clientutil.[ch]: silc_client_verify_server_key.
6177 * Changed SKE protocol's silc_ske_initiator_finish function
6178 to accept callback function that verifies the received public
6179 key. Removed old silc_ske_verify_public_key function.
6181 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6184 silc_pkcs_private_key[_data]_set.
6186 * Made the password and public authentication more cleaner in
6187 server's protocol.c.
6189 * Removed historic and obsolete protocol `channel_auth' from
6190 both client and server.
6192 * Removed wrong way of sending command status messages from
6193 server to client in server's command.c. The old way violated
6194 protocol specification.
6196 Changes to silccore/silccommand.[ch]: removed
6197 silc_command_encode_status_payload -> not needed anymore,
6198 changed silc_command_encode_payload_va to accept extra
6199 argument on variable argument list. The argument type must
6200 now be provided to the function. Also, added new function:
6201 silc_command_encode_reply_payload_va which is same as
6202 normal command_encode_payload_va except command status type
6203 is provided as extra argument.
6205 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Added ~./silc directory handling. The directory includes the
6208 public and private keys for the client.
6210 Added silc_client_check_silc_dir, silc_client_create_identifier
6211 and silc_client_load_keys.
6213 * Implemented SILC protocol compliant public key. Added public
6214 and private key saving to and loading from files.
6216 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6217 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6218 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6219 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6220 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6222 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6223 silc_pkcs_load_[public/private]_key.
6225 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added silc_server_get_route (route.[ch]) to get connection
6228 data for the fastest route for given ID.
6230 * Implemented INVITE command on client and server. The command
6231 were re-defined in the SILC Protocol Specification and the
6232 implementation now complies with the specification.
6234 * Implemented PING command on client and server.
6236 * Implemented NAMES command on client and server. The server side
6237 supports currently only normal server not router server yet.
6238 Some changes to NAMES definition in SILC protocol specification.
6240 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Implemented LEAVE command on client and server.
6244 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6245 again. This change was made to the protocol as well. Server
6246 should not violate the protocol specification anymore.
6248 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6251 was tested. SOCKS4 was not but should work anyway.
