1 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Update conn->local_entry->nickname after giving NICK
4 command. Affected file lib/silcclient/command.c.
6 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
8 * Save fingerprint in WHOIS command reply in server.
9 Affected file silcd/command_reply.c.
11 * Fixed NICK commands pending callback registration.
12 Affected file lib/silcclient/command.c.
14 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Use ++server->cmd_ident when sending commands in server,
17 instead of random number. Affected file silcd/command.c.
19 * Fixed GETKEY command reply to call actually GETKEY pending
20 command callbacks. Affected file silcd/command_reply.c.
22 * A bit stricter check for nicknames. Check for same nickname
23 in NICK command also. Affected file silcd/command.c.
25 * Do not call INFO command everytime client ID changes, only
26 during first connecting. Affected file lib/silcclient/client.c.
28 * Set the new nickname only after successful command reply for
29 NICK command is returned by server. Affected file
30 lib/silcclient/command.c.
32 * Remove nicknames from nicklist during server_signoff notify.
33 Should fix /NAMES bit more. The affected file is
34 irssi/src/silc/core/silc-channels.c.
36 * Added `fingerprint' field to the SilcIDListData in the
37 silcd/idlist.h to hold the fingerprint of the client's
40 Send the fingerprint of the client's public key in WHOIS
43 Affected files silcd/command.c, and silcd/idlist.[ch].
45 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
46 create fingerprint from given data.
48 * Show the fingerprint of the client's public key in WHOIS.
49 Affected files irssi/src/module-formats.[ch] and
50 irssi/src/silc/core/client_ops.c.
52 * Format the multiple same nicknames also during JOIN and
53 NICK_CHANGE notifys. Affected file is
54 lib/silcclient/client_notify.c.
56 * Do not print error on screen for invalid private message
57 payload since it can come if someone is sending private
58 messages with wrong key. Affected file
59 lib/silccore/silcprivate.c.
61 * Fixed multiple concurrent /PING crash. Affected file
62 lib/silcclient/command.c.
64 * Changed the wrong ID encoding. All IP addresses must be
65 in MSB first order in encoded format. They were encoded
66 wrong and was in LSB format. Affected files are
67 silcd/serverid.c, lib/silcutil/silcutil.c.
69 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
71 * Call the `connect' client operation through the scheduler
72 in case of error. Affected file lib/silcclient/client.c.
74 * Call the `failure' client operation even if the error
75 occurred locally during a protocol. Affected file is
76 lib/silcclient/protocol.c.
78 * Added support of sending LIST command to router from normal
79 server. This way normal server can get list of all channels
80 in the network too. Fixed the channel list sending in the
81 server too. Affected files are silcd/command.c, and
82 silcd/command_reply.[ch].
84 * Added silc_server_update_channels_by_server and
85 silc_server_remove_channels_by_server. They are used during
86 disconnection of primary router and in backup router protocol.
87 Affected file silcd/server_util.[ch], silcd/server.c and
88 silcd/server_backup.c.
90 * Fixed channel adding to global list in IDENTIFY command
91 reply in server. Affected file silcd/command_reply.c.
93 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
95 * If the incoming packet type is REKEY or REKEY_DONE process
96 that packet always synchronously. Fixes yet another MAC
97 failed error on slow (dialup) connections. Affected file
98 lib/silcclient/client.c and silcd/server.c.
100 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Call check_version SKE callback for initiator too. Affected
103 file lib/silcske/silcske.c.
105 * Implemented fix for security hole found in the SKE that was
106 fixed in the specification few days back; the initiator's
107 public key is now added to the HASH value computation.
108 Added backwards support for the old way of doing it too, for
109 old clients and old servers. Affected file is
110 lib/silcske/silcske.c.
112 * Enabled mutual authentication by default in SKE. If initiator
113 is not providing mutual authentication the responder will
114 force it. This will provide the proof of posession of the
115 private key for responder. The affected files are
116 lib/silcclient/protocol.c and silcd/protocol.c.
118 * Do not cache anymore the server's public key during SKE.
119 We do mutual authentication so the proof of posession of
120 private key is done, and if the server is authenticated in
121 conn auth protocol with public key we must have the public
122 key already. Affected file silcd/protocol.c.
124 * Added new global debug variable: silc_debug_hexdump. If
125 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
126 file lib/silcutil/silclog.[ch].
128 * Fixed compilation warning due to char * -> const char *.
129 Affected files lib/silcutil/silcnet.h, and
130 lib/silccore/silcauth.[ch].
132 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
134 * Fixed CMODE command when new channel key was created. If
135 the creation failed the old key was removed. Next time giving
136 same command would crash the server since the old key was
137 freed already. Affected file silcd/command.c.
139 * Fixed the silc_server_announce_get_channels to not crash
140 on reconnect. Affected file silcd/server.c.
142 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
144 * Added silc_log_set_debug_string function to set a regex
145 string to match for debug output. Only the function names,
146 or filenames matching the given debug string is actually
147 printed. This way it is possible to filter out those debug
148 strings that user is not interested in.
150 Fixed a bug in silc_string_regexify.
152 Affected files lib/silcutil/silclog.[ch], and
153 lib/silcutil/unix/silcunixutil.c.
155 * Changed the -d options in both server and Irssi SILC client
156 to take the debug string as argument. Affected files
157 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
159 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
161 * Added silc_hash_babbleprint to create a Bubble Babble
162 Encoded fingerprint. The encoding is developed by Antti
163 Huima (draft-huima-babble-01.txt), and it creates human
164 readable strings out of binary data. Affected file
165 lib/silccrypt/silchash.[ch].
167 * Print the babble print now in addition of fingerprint as well
168 in Irssi SILC client. Affected files are
169 irssi/src/fe-common/silc/module-formats.[ch],
170 irssi/src/fe-common/silc/core/client_ops.c.
172 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
174 * Fixed a security problem found in SKE. The initiator's
175 public key too is now added to the HASH hash value creation
176 which is signed by the responder to create the SIGN value.
177 This will prevent anyone in the middle to lie to the responder
178 about the initiator's public key. If this is done now, the
179 man in the middle will get caught. Updated the protocol
182 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Better installation directory handling. Configure module
185 paths and other paths automatically to example_silc* files
186 in doc/. A patch by toma.
188 * Fixed compiler warning from MPI library, and from SILC RNG.
191 * Added SILC_SERVER_PID_FILE to define the pid file for server.
192 It can be configured with ./configure. A patch by toma.
194 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
196 * Find correct make to use in prepare-clean. A patch by
197 toma. Affected file prepare-clean.
199 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
201 * Added irssi variables use_auto_addr, auto_bind_ip,
202 auto_bind_port and auto_public_ip.
204 * Changed the interface for silc_client_send_key_agreement
205 in lib/silcclient/silcapi.h
209 irssi/src/silc/core/silc-core.c
211 lib/silcclient/silcapi.h
212 irssi/src/silc/core/silc-channels.c
213 lib/silcclient/client_keyagr.c
216 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Added silc_pkcs_public_key_compare to compare two
219 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
221 * Check that the client who set the founder mode on the
222 channel is the same client that is giving the founder
223 mode to itself. It is done by comparing the saved public
224 key (it is saved even in the authentication is passphrase).
225 Affected file silcd/command.c.
227 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
229 * Do not process packet for disconnected socket connection.
230 Affected file lib/silccore/silcpacket.c.
232 * Process the DISCONNECT packet through scheduler in the
233 client library. Affected file lib/silcclient/client.c.
235 * Fixed the silc_client_packet_parse to not to increase
236 the packet sequence number if the conn->sock and the
237 current socket connection is not same. This can happen
238 for example during key agreement when the conn includes
239 multiple socket connections (listeners). Affected file
240 lib/silcclient/client.c.
242 * The sender of the file transfer request now provides also
243 the pointer (listener) for the key exchange protocol. If
244 the listener cannot be created then it sends empty key
245 agreement and lets the receiver provide the listener.
247 Added `local_ip' and `local_port' arguments to the
248 silc_client_file_send. If they are provided they are used,
249 if not then it will attempt to find local IP address, if
250 not found or bind fails then the remote client will provide
253 Affected files are lib/silcclient/client_ftp.c and
254 lib/silcclient/silcapi.h.
256 * Extended the FILE SEND command to support defining the
257 local IP and port for key exchange listener. They are
258 optional. Affected file irssi/src/silc/core/silc-servers.c.
260 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Defined to WHOIS command reply the sending of fingerprint
263 of the client's public key (if the proof of posession of the
264 corresponding private key is verified by the server).
265 Updated to the protocol specification.
267 * Added support of receiving the client's public key's
268 fingerprint in command reply in client library. Affected
269 file is lib/silcclient/command_reply.c, and
270 lib/silcclient/idlist.[ch].
272 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
274 * Do not send over 128 chars long nickname to the server
275 in NICK command. Affected file lib/silcclient/command.c.

278 in JOIN command. Affected file lib/silcclient/command.c.
280 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
282 * Assure that silc_server_close_connection cannot be called
283 twice for same socket context. Affected file is
286 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
288 * Send error message to application if opening file for
289 writing during file transfer fails. Affected file is
290 lib/silcclient/client_ftp.c.
292 Remove all file transfer sessions for a client that we're
293 removing from ID cache.
295 Affected file is lib/silcclient/client_ftp.c.
297 * Fixed silc_net_addr2bin to return correct address. Affected
298 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
300 * Fixed file transfer session removing on signoff notify.
301 Affected file irssi/src/silc/core/silc-servers.c.
303 * Added the SilcClientFileError to be returned in the monitor
304 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
305 Affected file lib/silcclient/silcapi.h.
307 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
309 * Fixed a crash in silc_client_ftp_free_sessions and
310 silc_client_ftp_session_free_client. Affected file
311 lib/silcclient/client_ftp.c.

314 to indicate if the server entry is disabled. Affected file
315 silcd/idlist.h, silcd/command[_reply].c.
317 * SILC server adds now /var/run/silcd.pid everytime it is
318 started. Affected file silcd/silcd.c.
320 * Added silc_server_packet_send_clients to send a packet to
321 the provided table of client entries. Affected file
322 silcd/packet_send.[ch].
324 * Fixed a crash in client resolving in client_prvmsg.c in
325 client library. Affected file lib/silcclient/client_prvmsg.c.
327 * Do not actually remove the client directly from ID cache
328 during SERVER_SIGNOFF, but invalidate it. This way we
329 preserve the WHOWAS info for the client. Affected file
332 * Fixed SERVER_SIGNOFF notify handling in the server. The
333 server is now able to process incoming SERVER_SIGNOFF notify
334 for a server that it doesn't even know about. It will remove
335 the clients provided in the notify. Affected file
336 silcd/packet_receive.c.
338 * Check for partial packet in data queue after every packet that
339 was found from the queue. Return and wait for more data if
340 there is partial data in queue. Affected file is
341 lib/silccore/silcpacket.c.
343 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
345 * Added SilcClietFileError enum to indicate error in
346 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
347 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
348 Affected files lib/silcclient/silcapi.h and

351 * Check that newsize in silc_buffer_realloc is larger than
352 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
354 * Added better monitor of file transfers. It now monitors
355 key agreement protocol during the file transfer too. Added
356 error reporting too. Affected files
357 irssi/src/silc/core/silc-servers.c,
358 irssi/src/fe-common/silc/module-formats.[ch].
360 * Wrote a help file for FILE command.
362 * Added silc_rng_global_get_byte_fast to get not-so-secure
363 random data as fast as possible. Random data is read from
364 /dev/urandom if available and from the SILC RNG if not
365 available. It is used in padding generation. Affected file
366 lib/silccrypt/silcrng.[ch].
368 * All packets in client library are now processed synchronously.
369 Optimized packet processing a lot. Affected file
370 lib/silcclient/client.c.
372 * All server connection packets are processing synchronously
373 now in server, to optimize packet processing. Affected file
376 * Include files are installed now only in Toolkit distribution
377 if make install is given. Affected files: all Makefile.am's.
379 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
381 * Assure that silc_client_notify_by_server_resolve does not
382 resolve the client information multiple times. If it cannot
383 be found by the first it cannot be found at all. Affected
384 file lib/silcclient/client_notify.c.
386 * Fixed WHOWAS command reply calling. Affected file
387 lib/silcclient/command_reply.c.
389 * Removed all references to silc_idlist_get_client from the
390 Irssi SILC client since that call is internal call used by
391 the library. The Irssi SILC client will use now client
392 retrieval functions found in silcapi.h.
394 * Fixed a bug in resolving nickname info before sending
395 private message. It used freed memory. Affected file
396 irssi/src/silc/core/silc-servers.c.
398 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
400 * Assure my_channels statistics cannot go negative in server.
401 Affected files silcd/server.c, silcd/server_util.c.
403 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

417 * Added silc_net_localip to return local host's IP address.
418 Affected file lib/silcutil/silcnet.[ch].
420 * If key exchange or rekey protocol is active for a connection
421 parse all packets syncronously since there might be packets
422 in packet queue that we are not able to process without first
423 processing packets before them. Affected file silcd/server,
424 lib/silcclient/client.c.
426 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
427 whether library should continue processing the packet.
428 Affected file lib/silccore/silcpacket.h.
430 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
431 SilcSFTPMonitorData to SFTP server to monitor various
432 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

459 lib/silcutil/silcutil.[ch].
461 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Resolve the client info when received private message or
464 channel message for a client which nickname we don't know.
465 Affected files lib/silcclient/client_prvmsg.c and
466 lib/silcclient/client_channel.c.
468 * Do not crash in /KEY if client is not connected. Affected
469 file irssi/src/silc/core/silc-channels.c.
471 * Added SilcClientStatus field to the SilcClientEntry in the
472 lib/silcclient/idlist.h.
474 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
475 is incomplete and is being resolved, it won't be resolved
478 Make sure also that USERS command reply does not resolve
479 twice information. Affected file is
480 lib/silcclient/command_reply.c.
482 Make sure that silc_client_get_clients_by_list does not
483 resolve twice same information.
485 * Check for valid client->id in the silc_server_free_client_data.
486 Affected file silcd/server.c.
488 * Fixed /GETKEY nick@server not to crash if the server entry
489 is not found. Affected file lib/silcclient/command.c.
491 * Fixed the silc_server_check_cmode_rights to check the
492 requested modes correctly. Affected file silcd/command.c.
494 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Better checks for non-printable chars in nick added.
497 Affected file silcd/command.c.
499 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Call the silc_server_udpate_servers_by_server in the
502 primary router that comes back online in the backup resuming
503 protocol. Otherwise it routes packets wrong. Affected file
504 silcd/server_util.[ch], silcd/server_backup.c.
506 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
508 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
509 lib/silcutil/silcbuffmt.[ch].
511 * Redefined the SILC packet header to include the padding
512 length. Affected file lib/silccore/silcpacket.[ch].
514 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
515 length for maximum padding up to 128 bytes). Affected
516 file lib/silccore/silcpacket.h.
518 * Removed all backwards support for old 0.5.x MAC thingies.
519 The SILC packet header change makes it impossible to be
520 backwards compatible.
522 * Send the ENDING packet with timeout in the backup resuming
523 protocol. This is to assure that all routers has connected
524 to the primary router. Affected file silcd/server_backup.c.
526 * Changed the RNG to take the first IV from random data. It
527 used to take it from zero actually. Changed the RNG also
528 to use /dev/urandom during session. /dev/random is used
529 in initialization. Affected file lib/silccrypt/silcrng.[ch].
531 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
533 * Changed the SILC packet header to have the first two bytes
534 (the packet length) encrypted. Affected files aroung the
535 code tree, lib/silccore/silcpacket.[ch]. Removed the
536 SilcPacketCheckDecrypt callback. It is not needed anymore
537 since the silc_packet_receive_process will determine now
538 whether the packet is normal or special.
540 * Implemented the unidirectional MAC keys. Affected files
541 lib/silcske/silcske.c, silcd/protocol.c and
542 lib/silcclient/protocol.c.
544 * Implemented the packet sequence number to the MAC computation.
545 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
546 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
547 lib/silcclient/protocol.c.
549 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
551 * Allow backup router to announce servers. All servers
552 announced by backup router are added to the global list
553 automatically. Update hte server's socket to our primary
554 router also when backup router announces a server.
555 Affected file silcd/packet_receive.c.
557 * Do not update the client->router in the function
558 silc_server_udpate_clients_by_server if the client is on
559 global list. We might fail to find any specific server
560 for locally connected clients and local cell clients. They
561 should still use the `from' and not `to' as client->router.
562 This fixes backup router resuming protocol. Affected file
565 * Decrease channel statistics count only if the channel
566 deletion worked. Affected files are silcd/server.c and
569 * Added silc_server_update_servers_by_server to update origin
570 of all server entries. Used during backup router protocol.
571 Affected files silcd/server_util.[ch], silcd/server.c. and
572 silcd/backup_router.c.
574 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
575 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
576 silc_hmac_get_hash and silc_hmac_get_name. Affected file
577 lib/silccrypt/silchmac.c.
579 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Assure that router cannot reroute the same channel message
582 to the sender. Affected file silcd/packet_receive.c.
584 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Made better checks that the channel message is not sent
587 to the router it came from. Affected file is
588 silcd/packet_send.c. Fixed memory leak too.
590 * Announce informations for incoming router connection, but
591 only after checking if it is replaced by backup router.
592 Affected file silcd/packet_receive.c.
594 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
596 * Fixed the backup resuming protocol to work in multiple
597 router environment. Affected file silcd/server_backup.c.
599 * Route packet only to one router in the function
600 silc_server_packet_send_to_channel. Affected file is
603 * Fixed silc_server_send_notify_dest to set the broadcast
604 flag. Fixed the silc_server_send_notify_topic to actually
605 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
606 Affected file silcd/packet_send.c.
608 * Changed the SFTP Filesystem interface. Changed the
609 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
610 the filesystem operation function. The SilcSFTPFilesystem
611 is now a context that is allocated by all filesystem allocation
612 functions and it already includes the operations structure
613 and filesystem specific context. It is given as argument
614 now to the silc_sftp_server_start. This made the interface
615 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
616 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
618 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Changed the backup router adding and getting interfaces
621 in the server. The router that will be replaced by the
622 specified backup router is now sent as argument. Affected
623 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
626 * Added silc_net_addr2bin_ne to return the binary form of
627 the IP address in network byte order. Affected files
628 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
630 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Check for existing server ID in silc_server_new_server
633 and in silc_server_connect_to_router_final and remove the
634 old entry if it exists. Affected file silcd/packet_receive.c,
637 * Send the channel message always to only one router, either
638 in upstream or downstream. Affected file is
641 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Wrote the definition of the backup resuming protocol to the
644 protocol specification.
646 * Removed one redundant channel key generation from normal
647 server during joining procedure. Removed one redundant
648 channel key sending from server to router during joining
649 procedure. Affected file silcd/command.c.
651 * Made minor bugfixes to the backup router resuming protocol.
652 Affected file silcd/server_backup.c, server.c.
654 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Added --disable-asm configuration option. Affected files
657 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
660 * Implemented the backup resuming protocol that is used to
661 resume the primary router position in the cell after the
662 primary router comes back online. Affected files
663 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
664 and silcd/server_util.[ch].
666 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Sleep two (2) seconds after sending QUIT command to server.
669 Affected file lib/silcclient/command.c.
671 * Assure that if outgoing data buffer is pending do not force
672 send any data. Affected file silcd/packet_send.c.
674 * Assure that if outgoing data buffer is pending do not force
675 send any data. Affected file lib/silcclient/client.c.
677 * Implemented the backup router support when the primary router
678 goes down. The servers and routers can now use the backup
679 router as new primary router without loosing connectivity.
681 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
683 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
684 in the server to indicate disabled entry. All data read
685 from the connection will be ignored and no data is sent
686 for entry that is disabled. Affected files are
687 silcd/idlist.h, silcd/server.c.
689 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Created SFTP client and server test programs in the
692 lib/silcsftp/tests directory.
694 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
696 * Implemented memory filesystem (virtual filesystem) for
697 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
700 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
702 * Implemented the SFTP (SSH File Transfer Protocol) to the
703 lib/silcsftp. It includes SFTP client and SFTP server
706 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
708 * Moved lib/silccore/silcprotocol.[ch] to the
709 lib/silcutil library.
711 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
712 take variable argument list pointer as argument. Affected
713 file lib/silcutil/silcbuffmt.[ch].
715 * Added silc_buffer_set function that is used to set data
716 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
717 Affected file lib/silcutil/silcbuffer.h.
719 * Changed various routines in the core library to use the new
720 silc_buffer_set instead of allocating new buffer only for
723 * Added 64-bit value formatting and unformatting support to the
724 silc_buffer_[un]format routines. Affected file is
725 lib/silcutil/silcbuffmt.[ch].
727 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
728 to includes/bitmove.h.
730 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Fixed channel user mode saving in client library. Affected
733 file lib/silcclient/command[_reply].c.
735 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Defined the file transfer to the SILC Protocol. Added
738 new packet type SILC_PACKET_FTP and defined File Transfer
739 Payload. The mandatory file transfer protocol is SFTP
740 (SSH File Transfer Protocol). Affected file in addition
741 of the internet draft is lib/silccore/silcpacket.h.
743 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
744 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
745 is used as part of backup router protocol when the primary
746 router of the cell is back online and wishes to resume
747 the position as primary router.
749 * Redefined the MAC generation keys in the protocol. The
750 same key is not used anymore in both direction. Both
751 direction will now use different keys for sending and
752 receiving. This fixes a potential security flaw. This
753 change causes incompatibilities in the protocol.
755 * Redefined also the MAC computation from the packet.
756 An packet sequence number is now added to the MAC
757 computation. This prevents possible replay attacks against
758 the protocol. This change too causes incompatibilities
761 Added `sequence' field to the SilcPacketContext to hold
762 the current sequence number for the packet.
764 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
766 * Added `created' field to the SilcIDListData in the file
767 silcd/idlist.h to indicate the time when the entry was
770 * Added `created' field to the SilcChannelEntry too. Affected
773 * Added `creation_time' aguments to all the announcement functions
774 in the server. If it is provided then only the entries that
775 was created after the provided time frame are actually
776 announced. Affected file silcd/server.[ch].
778 * The protocol says that the Channel ID's IP address must be
779 based on the router's IP address. Added check for this in
780 the silc_server_new_channel when processing incoming New Channel
781 Payload. Affected file silcd/packet_receive.c.
783 * Print out the correct version with --version in SILC client.
784 Affected file irssi/src/silc/core/silc-core.c.
786 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Fixed WHOWAS command to check for completnes of the client
789 entry always, not just when the command is coming from client.
790 Affected file silcd/command.c.
792 * Added new function silc_server_packet_queue_purge to purge the
793 outgoing data queue to the network. After the function returns
794 it is guaranteed that the outgoing packet queue is empty.
795 Affected file silcd/packet_send.[ch].
797 * Purge the outgoing packet queue in the rekey protocol's final
798 callback to assure that all rekey packets go to the network
799 before quitting the protocol. Affected file silcd/server.c.
801 * Added silc_client_packet_queue_parse as similar function as
802 in server to the client library. The affected file is
803 lib/silcclient/client.c.
805 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Splitted silcd/server.c and created silcd/server_util.[ch]
808 for utility functions.
810 * Added new socket flag SILC_SF_DISABLED to indicate that the
811 connection is open but nothing can be sent to or received from
812 the connection. Affected file lib/silcutil/silsockconn.[ch].
813 The checking for disabled socket is checked in the low level
814 silc_socket_write and silc_socket_read functions.
816 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Allow only nicknames and channel names that fits into the
819 7-bit unsigned char ASCII set. Affected file silcd/command.c.
821 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
823 * When processing JOIN command reply in server check that if
824 the channel exists in our global list we'll move it the local
825 list. Affected file silcd/command_reply.c.
827 * Fixed the check whether client is joined on the channel already
828 in JOIN command. Affected file lib/silcclient/command.c.
830 * Fixed the JOIN command reply to check whether the channel
831 already exists. Affected file lib/silcclient/command_reply.c.
833 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
835 * Added silc_ske_status_string to map the SKE error numbers
836 to readable strings. The affected files are
837 lib/silcske/silcske[_status].[ch].
839 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Do not show the private channels on the WHOIS channel list
842 as it is not allowed by the protocol. The affected file is
845 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Assure that the packet length digged from the actual packet
848 is something sensible in the silc_packet_decrypt_rest_special
849 in lib/silccrypt/silcpacket.c.
851 * Free and NULL the allocated pointer in silc_hmac_alloc if
852 the HMAC allocation fails. The affected file is
853 lib/silccrypt/silchmac.c.
855 * Print the selected security properties to the log files in
856 the server. Affected file silcd/protocol.c.
858 * Add SKE's reference counter even if calling the completion
859 callback manually. Otherwise it goes negative, although it
860 does not cause any problems. The affected file is
861 lib/silcske/silcske.c.
863 * Remove the client entry with short timeout after giving the
864 KILL command. Affected file lib/silcclient/command.c.
866 * Fixed to send error reply in WHOIS and IDENTIFY commands in
867 case all found clients are already disconnected (WHOWAS would
868 found them) in the server. Affected file silcd/command.c.
870 * Update the last_receive (time of last data received) to be
871 updated only when received private or channel message so that
872 the idle time showed in WHOIS makes more sense.
874 * Added boolean field `valid' in to the SilcClientEntry in the
875 client library to indicate whether the entry is valid or not.
876 This fixes the nickname change bug on channel when changing
877 the nickname to be same than the old (like nick to Nick) the
878 nickname formatter doesn't set the new nick anymore to Nick@host.
879 Affected file lib/silcclient/idlist.[ch].
881 * Now actually fixed the nickname changing on disconnection.
882 Added new function silc_change_nick to the Irssi SILC Client.
883 Affected file irssi/src/silc/core/client_ops.c,
884 irssi/src/silc/core/silc-nicklist.[ch].
886 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Check that the public key exists in the GETKEY command before
889 trying to encode it. Affected file silcd/command.c.
891 * Print some notifications on received public keys with GETKEY
892 command in the Irssi SILC Client. Affected files are
893 irssi/src/fe-common/silc/module-formats.[ch],
894 irssi/src/silc/core/client_ops.c.
896 * Use IDENTIFY command to resolve the server information in the
897 GETKEY command instead of INFO command. Affected file
898 lib/silcclient/command.c.
900 * All command reply functions in the client library now calls
901 the pending command reply callbacks even if an error has
902 occurred. The server has done this a long time and now it was
903 time to move the client library to this as well. Now all
904 errors can be delivered back to the pending command reply
905 callbacks if necessary. Affected files are
906 lib/silcclient/command[_reply].[ch].
908 * Change the nickname on disconnection back to the username
909 because in reconnect the server will enforce it to it anyway.
910 Affected file irssi/src/silc/core/silc-servers.c.
912 * Fixed a config file parsing bug in the Irssi SILC client.
913 Affected file irssi/src/silc/core/clientconfig.c.
915 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
917 * When printing the channel mode on JOIN, verify that the
918 channel key and channel's HMAC are valid. Affected file
919 irssi/src/silc/core/client_ops.c.
921 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
923 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
924 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
925 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
927 * Removed channel key rekey task deleting from the function
928 silc_server_save_channel_key. Affected file silcd/server.c.
929 Added explicit timeout task context instead that is used to
930 delete the task if we are registering a new task before the
931 new task has elapsed.
933 * When channel key rekey occurs the client library now saves
934 the old channel key for a short period of time (10 seconds) and
935 is able to use it in case some is still sending channel
936 messages encrypted with the old key after the rekey. Affected
937 file lib/silcclient/[idlist.h|client_channel.c].
939 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
941 * Added check to the silc_server_new_id_real to not accept
942 new ID if it is the sender's own ID. Affected file is
943 silcd/packet_receive.c.
945 * Assure that we do not announce ourself or the one we've
946 sending our announcements when we're router and are announcing
947 servers to our primary router. Affected file silcd/server.c.
949 * Fixed silc_server_command_identify_check_client to assemble
950 correct WHOIS packet. It send corrupted WHOIS packet and
951 caused problem with router to router connections. Affected
952 file silcd/command.c.
954 Fixed also silc_server_command_whois_check the same way
955 as for the IDENTIFY command.
957 * Added new SilcIDListStatus to the server in the SilcIDListData
958 structure. The status now includes the current status of
959 the entry (like registered, resolved etc.). Affected file
960 silcd/idlist.[ch]. Defined a bunch of different status types
961 as well. This replaced the old boolean registered field as well.
963 Added resolve_cmd_ident field to the SilcClientEntry structure
964 too so that if the entry is for example being resolved so
965 another command may attach to the same pending command reply
966 without requiring to resolve the same entry again. This concept
967 should optimize the WHOIS and the IDENTIFY resolving under
968 heavy load by taking away unnecessary resolving for entries
969 that are being resolved already.
971 Added support for adding multiple pending commands for one
972 command idenfier. Affected file silcd/command[_reply].[ch].
974 * Fixed WHOIS and IDENTIFY save to remove the cache entry
975 before deleting the data. Otherwise the hash table will have
976 freed data in comparison functions. Affected file is
977 silcd/command_reply.c.
979 * Fixed silc_idlist_replace_client_id to add the new entry to
980 the cache with NULL nickname. Otherwise there will be invalid
981 memory as the nickname after the nickname is freed. Affected
982 file silcd/packet_receive.c.
984 * Fixed the silc_idlist_get_clients_by_hash. The entries was
985 saved into wrong slots because the previous number of entries
986 was not taken into account. Affected file silcd/idlist.c.
987 Fixed same thing in silc_idlist_get_clients_by_nickname too.
989 * If we are router and we receive JOIN notify to a channel that
990 does not have any users then notified client is marked as the
991 channel founder, as it is it. The affected file is
992 silcd/packet_receive.c
994 * Added to the extended hash table API's table_del_*ext functions
995 the destructor as argument too, so that the caller can decide
996 which destructor to use or whether to use destructor at all.
997 Affected file lib/silcutil/silchashtable.[ch].
999 * Fixed ID Cache purging. It actually deleted the entries from
1000 the hash table after the data was freed. The hash table ended
1001 up comparing freed memory. The affected file is
1002 lib/silccore/silcidcache.c.
1004 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Fixed Irssi SILC client's KILL command's HELP syntax.
1008 * The USERS command now resolves the detailed user information
1009 if the userinfo field is missing. Affected file is
1010 lib/silcclient/command_reply.c.
1012 * Do not print error in silc_file_read if the read file does
1013 not exist. Just silently return NULL. Affected file is
1014 lib/silcutil/silcutil.c.
1016 * Fixed the silc_log_output to not wine about NULL filename
1017 and to not create some bogus " " filename. Affected file is
1018 lib/silcutil/silclog.c.
1020 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Fixed various printing bugs on the user interface in the
1023 Irssi SILC Client. Minor changes that were forgotten from
1026 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Fixed the configure.in.pre and the compilation and distribution
1029 environment to support the new autoconf 2.52. That version is
1030 now required to compile the CVS trunk.
1032 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1035 to generally parse user@fqdn format strings. Affected file
1036 lib/silcutil/silcutil.c.
1038 * Added nickname_format and nickname_force_format fields to the
1039 SilcClientParams structure. The first one defines the format
1040 for the nicknames that the library will enforce if the receives
1041 multiple same nicknames. The second one is boolean value and
1042 can be used to force the library to always enforce the format
1043 to the nicknames regardles whether there are multiple nicknames
1044 or not. This configurable formatting was employed to flexibly
1045 support accessing multiple nicknames from the user interface.
1046 The userinterface can now set the nicknames to what ever format
1047 they prefer. Affected file lib/silcclient/silcapi.h.
1049 Added function silc_client_nickname_format to the file
1050 lib/silcclient/idlist.c. It performs the nickname formatting.
1052 Added new field `hostname´ to the SilcClientEntry context.
1053 It holds the hostname of the client. Affected file is
1054 lib/silcclient/idlist.h.
1056 * Irssi SILC Client sets the nicknames in nick@hostn format.
1057 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1058 irssi/src/silc/core/silc-core.c.
1060 The WHOIS printing now also shows both the real nickname and
1061 the formatted nickname so that user knows how to access the
1062 user if there are multiple same nicknames cached. Affected
1063 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1064 printing formatting too to take the hostname now as a separate
1065 argument. The Affected file is
1066 irssi/src/fe-common/silc/modules-formats.[ch].
1068 * Changed the silc_client_get_clients_local to accept the formatted
1069 nickname as argument. It accepts the real nickname too but the
1070 formatted nickname can be used to find the true entry from
1071 multiple entries. Affected file lib/silcclient/silcapi.h and
1072 lib/silcclient/idlist.c.
1074 * Added nickname_format_parse field to the SilcClientParams.
1075 It is a callback function provided by the application to parse
1076 the nickname out of the formatted nickname string. The library
1077 calls it to get the nickname from the formatted string. Since
1078 the application generally knows better the format of the nickname
1079 string it parses it instead of the library, even though library
1080 encodes the formatted string. If the callback function is not
1081 provided then the library will use the string as is. The
1082 affected file is lib/silcclient/silcapi.h.
1084 * All the nickname strings passed to the client library in
1085 commands are now expected to be formatted nickname strings.
1086 If the command does not support the formatted nickname string
1087 it will assume that the sent string is the actual nickname.
1088 Affected file lib/silcclient/command.c.
1090 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Added public key authentication support to OPER and SILCOPER
1093 commands in the client library. Affected file is
1094 lib/silcclient/command.c.
1096 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Changed the get_auth_methdod client operation to be asynchronous.
1099 It can be async if the application resolves the authentication
1100 method from the server during the negotiation. Added new
1101 SilcGetAuthMeth completion callback that the application will
1102 call after resolving the authentication method.
1104 Added function silc_client_request_authentication_method that
1105 the application can use to resolve the authentication method
1106 from the server. Added also SilcConnectionAuthRequest callback
1107 that the library will call after the server has replied. The
1108 application can call this function if it does not know the
1109 current authentication method.
1111 Affected files are lib/silcclient/client.c and
1112 lib/silcclient/silcapi.h.
1114 * The Irssi SILC client now automatically resolves the authentication
1115 method incase any configuration information is not present (and
1116 currently there never is). The affected file is
1117 irssi/src/silc/core/client_ops.c.
1119 * Fixed public key authentication from the client library.
1120 Affected file lib/silcclient/protocol.c. Changed also the
1121 protocol specification about the public key authentication in
1122 the connection authentication protocol. The actual data to be
1123 signed is now computed with a hash function before signing.
1125 * Fixed the public key authentication from the server as well.
1126 Affected file silcd/protocol.c.
1128 * Removed the mlock()'s from the memory allocation routines.
1129 Affected file lib/silcutil/silcmemory.c. The ./configure does
1130 not check anymore for the mlock(). Affected file is
1133 * Fixed USERS command in server to allow the execution of the
1134 command for private and secret channels if the client sending
1135 the command is on the channel. Affected file silcd/command.c.
1137 * Fixed silc_client_get_clients_local to return the clients
1138 count correctly. It could return wrong value. Affected file
1139 lib/silcclient/idlist.c.
1141 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1144 types. The assembler optimizations seemed not to like 64-bit
1145 data types. The assmebler optimizations thus are now enabled
1146 also for BSD systems as opposed to only enable them for Linux.
1148 * Do not check for threads at all on BSD systems. Affected
1149 file configure.in.pre.
1151 * Removed -n and -h options from the Irssi SILC Client since
1152 they are not used in silc.
1154 * Fixed the prime generation to assure that the first digit
1155 of the generated random number is not zero since our conversion
1156 routines does not like number strings that starts with zero
1157 digit. If zero digit is seen the random number is regenerated.
1158 This caused some corrupted RSA keys when the zero first digit
1159 was met. Affected file lib/silcmath/silcprimegen.c.
1161 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1163 * Fixed WIN32 configuration in the ./configure script.
1164 Fixed to include xti.h on environments that has it.
1165 Patches by Carsten Ilchmann and andrew.
1167 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Changed the silc_id_create_client_id to be collision
1170 resistant. It is now assured that there cannot be created
1171 two same client ID's. I suspect that some weird bugs in
1172 the server were actually caused by duplicate Client IDs.
1173 Affected file silcd/serverid.[ch]. A router receiving
1174 new ID now also assures and informs the sending server
1175 if the ID caused collision.
1177 * Changed the silc_id_create_channel_id to also assure that
1178 there are no collisions.
1180 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Statement about ignoring the Mutual Authentication flag when
1183 performing rekey with PFS was a bit misleading. It is ignored
1184 if it was set in the initial negotiation, it cannot be even
1185 set in the rekey. Fixed in the ke-auth draft. Started the
1186 new versions of the protocol drafts in the doc/.
1188 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Fixed a bug in silc_client_command_identify_save when saving
1191 new channel information. The channel name was no duplicated
1192 and caused crash on exit. Affected file is
1193 lib/silcclient/command_reply.c.
1195 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Fixed the getkey command handling in the server. Send just
1198 empty OK reply to the sender if the key could not be fetched
1199 (but everything else was ok, like the key just was not available).
1200 Changed the public key parameter to optional in the protocol
1201 specs so that empty OK reply can be sent. Affected file
1204 Added a message to Irssi SILC client to tell to user if the
1205 server did not return a public key.
1207 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Fixed a channel key regeneration bug. It registered new
1210 timeout tasks exponentially until all system resources were
1211 used. Affected file silcd/server.c.
1213 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Added the SILC Document generator to the scripts/silcdoc.
1216 It can be used to generate the Toolkit Reference Manual out
1217 of the source tree. Internally it will also use the RoboDoc
1218 generator now imported in util/robodoc.
1220 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Added couple of return's in rekey protocol if error orccurred
1223 during the protocol. The execution must be terminated.
1224 Affected file silcd/protocol.c. Also, terminate the protocol
1225 always with timeout.
1227 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * The client's Client ID was created initally from the wrong
1230 nickname (it could have been in format nick@host) in the
1231 silc_server_new_client. Affected file silcd/packet_receive.c
1233 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Added some SILC_LOG_ERROR's to various error conditions
1236 if client could not be added to ID cache. Affected files
1237 silcd/packet_receive.c and silcd/server.c.
1239 * When client's sock->user_data is freed, NULL also the
1240 client->router and client->connection pointers. Added check
1241 for these pointers being NULL to various places around the
1242 code. Affected file silcd/server.c.
1244 * Added client->data.registered == TRUE checks to various
1245 places around the code to assure that unregistered client's
1246 are not handled when it is not allowed. Affected file
1249 * Added `bool registered' fields to all
1250 silc_idlist_[server|client]_get_* routines to indicate whether
1251 the fetched client needs to be registered or not. Affected
1252 file silcd/idlist.[ch].
1254 * Add your own entry as registered to the ID cache in the
1255 server. Affected file server.c.
1257 * Fixed a bug in silc_server_new_server. The SilcServer was
1258 set as the new server's context instead of SilcServerEntry.
1259 This naturally caused some weird bugs.
1261 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Do not delete the channel rekey task when adding it
1264 for in silc_server_create_channel_key.
1266 * Changed the silc_server_create_channel_key to return
1267 TRUE or FALSE to indicate the success of the channel key
1270 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Fixed MSVC++ project files and added missing files to
1273 Makefiles under win32/.
1275 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Do not add TCP_NODELAY flag if the operating system
1278 does not have it defined. Affected files are
1279 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1281 * Fixed buffer overflow from Irssi SILC Client. Affected
1282 file irssi/src/fe-common/core/themes.c.
1284 * Fixed double free in client library in the file
1285 lib/silcclient/client.c when disconnecting from server.
1287 * Applied double free patch from cras to Irssi SILC client.
1288 Affected files irssi/src/core/[modules/expandos].c
1290 * Fixed the disconnection handling to Irssi SILC Client.
1291 The application must call silc_client_close_connection
1292 in ops->connect client operation in case of failure of
1293 the connection. Affected file is
1294 irssi/src/silc/core/client_ops.c.
1296 * Do not set sock->protocol to NULL in the function
1297 silc_client_close_connection after executing the protocol's
1298 final callback since the sock might not be valid anymore.
1299 Affected file lib/silcclient/client.c.
1301 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * Do not enable SILC_THREADS if the linking with libpthread
1304 did not happen. Affected file configure.in.pre.
1306 * Added notion to protocol specification that server must
1307 verify the sent authentication payload with CMODE when
1308 setting the channel founder key. Implemented it to the
1309 server. Affected file silcd/command.c.
1311 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Added _EXTRA_DIST SILC distribution variable to the
1314 distributions file. It is used to conditionally add extra
1315 files or directories to the specific distribution. Affected
1316 files ./prepare, Makefile.am.pre and distributions.
1318 Removed the `_' from the start of the distribution names.
1321 * Added README.WIN32 for instructions to compile the Toolkit
1324 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Fixed a double free in disconnection in the server. Affected
1327 file is silcd/server.c.
1329 * Fixed the lib/silcske/groups.c to work now also with GMP
1330 MP library. The string conversion did not work when using
1331 specific base and the base is indicated in the string as well.
1333 * Created win32/ directory which now includes MSVC++ specific
1334 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1335 It will appear only in the toolkit distribution
1337 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Changed the key material distribution function in case when
1340 the hash output is too short. The data is now concatenated
1341 a bit differently than it used to. Made the change to the
1342 SKE protocol specification.
1344 * Added better GMP detection to configure.in.pre. A patch
1347 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * Fixed a minor bug in SKE that might cause some problem on
1350 some platforms. Affected file lib/silcske/silcske.c.
1352 * Added the cookie checking for initiator in the SKE. It checks
1353 that the responder returns the sent cookie unmodified. The
1354 affected file is lib/silcske/silcske.c. Added new SKE
1355 error type INVALID_COOKIE that can be sent during the
1356 negotiation. Fixed some memory leaks as well.
1358 * Added the "invalid cookie" error message to Irssi SILC client's
1361 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Added `task_max' field to the SilcClientParams to indicate
1364 the maximum tasks the scheduler can handle. If set to zero,
1365 default values are used. Affected file lib/silcclient/silcapi.h.
1367 * Fixed memory leaks in silc_client_close_connection. Affected
1368 file lib/silcclient/client.c.
1370 * Added silc_client_del_client_entry to client library to free
1371 all memory of given client entry. Affected file is
1372 lib/silcclient/idlist.[ch].
1374 * Added new functions silc_client_del_channel and
1375 silc_client_del_server to delete channel and server entries.
1376 Affected file lib/silcclient/[silcapi.h/idlist.c].
1378 * Removed silc_client_del_client_by_id from silcapi.h.
1380 * Fixed the INFO command to return the server's own info
1381 correctly when querying by Server ID. Affected file is
1384 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Removed the non-blocking settings in WIN32 code in the
1387 silc_sock_[read/write] and added SleepEx instead. Affected
1388 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1389 of input data is now checked with FIONREAD and ioctlsocket.
1391 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Call silc_schedule_task_del_by_context in the
1394 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1395 Affected file lib/silccore/silcprotocol.c.
1397 * Call silc_protocol_cancel for active protocols in the
1398 silc_server_close_connection if the funtion
1399 silc_server_free_sock_user_data has not been called.
1400 Affected file silcd/server.c.
1402 * Generic tasks cannot be deleted using the del_by_fd
1403 task deleting function since generic tasks does not match
1404 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1406 * Added a notion to SILCOPER help file that the SILCOPER works
1407 only on router server, not on normal server.
1409 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Added for WIN32 support for the new scheduler as well.
1412 Affected file lib/silcutil/win32/silcwin32schedule.c.
1414 * Fixed the SHA1 implementation to work on various platforms.
1416 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1419 API. It is part of the scheduler now. Everything else is
1420 as previously but some functions has changed their names.
1421 Checkout the lib/silcutil/silcschedule.h for the interface.
1422 Updated all applications to use the new interface. Affected
1423 files are lib/silcutil/silcschedule.[ch].
1425 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Found a bug in the SKE implementation. The HASH value,
1428 specified by the protocol, was not computed correctly. The
1429 public key of the responder was not added to the computation
1430 even though it is mandatory. Affected file lib/silcske/silcske.c.
1431 This unfortunately causes incompatibilities with older
1432 clients and servers.
1434 * Added WIN32 specific network init and uninit functions:
1435 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1436 the Winsock2. Affected file lib/silcutil/silcnet.h and
1437 lib/silcutil/win32/silcwin32net.c.
1439 * Set the socket always to nonblocking mode on WIN32 after
1440 reading data or writing data. Affected file is
1441 lib/silcutil/win32/silcwin32sockconn.c.
1443 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Fixed various compilation problems under WIN32. Affected
1446 files lib/silcutil/win32/silcwin32thread.c and
1447 lib/silcutil/win32/silcwin32schedule.c.
1449 * Removed all _internal.h #includes from public header
1450 files. Internal headers must never be included from
1453 Removed also the lib/silcske/payload_internal.h file.
1455 * All include files that may be needed (public and some others
1456 included by the public headers) by application developers are
1457 now copied to the ./includes directory. It does not copy any
1458 internal headers. Affected file Makefile.defines.pre and all
1459 Makefile.am's under lib/ and subdirs.
1461 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Do not change the ~/.silc directory's permissions automatically.
1464 Affected file irssi/src/silc/core/clientutil.c.
1466 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Do not cancel the protocol in silc_server_close_connection
1469 it might cause recursion. Now cancelled in the function
1470 silc_server_free_sock_user_data. Affected file silcd/server.c.
1472 * Fixed the silc_server_remove_clients_by_server to regenerate
1473 the channel keys correctly finally. Added also new function
1474 silc_server_remove_clients_channels to actually do it.
1475 Affected file silcd/server.c.
1477 * Fixed the silc_server_new_channel to not crash by giving
1478 wrong router to the new channel. Affected file is
1479 silcd/packet_receive.c.
1481 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1484 which is given as argument to the silc_client_alloc now.
1485 It can be used to configure the client and set various parameters
1486 that affect the function of the client.
1488 * The USERS command in server did not check whether the channel
1489 is private or secret. Affected file silcd/command.c.
1491 * Added new argument to the USERS command in protocol specification.
1492 The USERS command now can take the channel name as argument
1493 as well. Added support for this in client and server and
1494 updated the protocol specs.
1496 * Completed the GETKEY command in client. It can be now used
1497 to fetch also servers public key not only some clients.
1498 Affected files lib/silcclient/command[_reply].c.
1500 * Added silc_client_get_server to return server entry by the
1501 server name. Affected files lib/silcclient/silcapi.h and
1504 * Redefined the IDENTIFY command in protocol specification to be
1505 more generic. It now can be used to query information about
1506 any entity in the SILC Network, including clients, servers and
1507 channels. The query may be based either the entity's name
1508 or the ID. Added support for this in both client and server.
1510 Affected files silcd/command.c and lib/silcclient/command.c
1511 and command_reply.c.
1513 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1514 the _from_client and _from_server functions. Affected file
1517 * Added silc_client_get_channel_by_id_resolve to the file
1518 lib/silcclient/silcapi.h to resolve channel information by
1519 its ID. Added also silc_client_get_channel_by_id that
1520 does not resolve it from the server.
1522 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Added SilcServerEntry context into the client library
1525 to represent one server. The INFO command now allocates
1526 these to save the resolved server info. For now on the
1527 client library will also keep information about servers,
1528 connected and resolved with INFO.
1530 The INFO command now allocates the SilcServerEntry context
1531 and saves the server info there. The COMMAND_REPLY in
1532 the INFO now returns the parameters to application in
1533 same order as defined in the protocol specification.
1535 The entries are cached in the client->server_cache.
1537 * The INFO command is now issued after received the Client ID
1538 from the server. Affected file lib/silcclient/client.c.
1540 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1541 to the application as the mode changer might be server.
1542 It is guaranteed that NULL is not returned anymore to the
1543 application. Affected file lib/silcclient/client_notify.c.
1545 The ID Type is now also passed to the application so that
1546 it can check whether the returned entry is SilcClientEntry
1549 Added new function silc_client_get_server_by_id to return
1550 the server entry by ID. Affected files are the
1551 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1553 * Do not create the channel in the Irssi SILC Client when issuing
1554 the JOIN command but when received the sucessful JOIN command
1555 reply. Otherwise the channel might get created even though we
1556 could not join it. The Affected file is
1557 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1559 * Fixed a channel joining bug in router. The router must also
1560 check the channel modes, invite and ban lists etc. when serving
1561 the JOIN command sent by normal server. Affected file is
1562 silcd/command.c. The router now resolves the client's
1563 information from the server who sent the JOIN command if it
1564 does not know it, and processes the JOIN command only after
1567 * Changed the SilcCommandCb to take new argument; void *context2.
1568 Affected file lib/silccore/silccommand.h
1570 The second argument in the command callbacks in the server now
1571 includes the SilcServerCommandReplyContext if the command was
1572 called as pending command callback from the command reply.
1573 Otherwise it is NULL. When called as pending the status of the
1574 command reply will be checked and if it was erronous the
1575 error will be sent to the original sender of the command.
1576 This way the client always receives the error messages even
1577 though the server was actually the one who received the error
1578 when it resent the command to router, for example. Affected
1579 files silcd/command[_reply].[ch].
1581 * Fixed sending WHOWAS command's error message to client if
1582 the requested client could not be found. It was missing.
1585 * Changed the CMODE and CUMODE commands reply arguments in the
1586 protocol specification. The Channel ID is now sent in both
1587 of the commands to identify the channel. Implemented this
1588 new feature to the client and server. Affected files
1589 lib/silcclient/command_reply.c and silcd/command.c.
1591 * Made better checks for invite and ban lists in the JOIN
1592 command in server. Affected file silcd/command.c.
1594 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * The server now performs the incoming host IP/DNS lookup
1597 using the silc_socket_host_lookup and thus does not block
1598 the server anymore. Affected file silcd/server.c.
1600 * Completed the multi-thread support for SILC Scheduler in
1601 the lib/silcutil/silcschedule.c.
1603 * Fixed the configure.in.pre to detect the pthread correctly
1606 * Fixed a deadlock in silc_task_queue_wakeup in the file
1607 lib/silcutil/silctask.c.
1609 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Added new function silc_schedule_wakeup that is used in
1612 multi-threaded environment to wakeup the main thread's
1613 schduler. It needs to be used when a thread adds a new task
1614 or removes a task from task queues. After waking up, the
1615 scheduler will detect the task queue changes. If threads
1616 support is not compiled in this function has no effect.
1617 Implemented the wakeup mechanism to both Unix and WIN32
1618 systems. Affected files are lib/silcutil/silcschedule.[ch],
1619 lib/silcutil/unix/silcunixschedule.c and the
1620 lib/silcutil/win32/silcwin32schedule.c.
1622 * Added new function silc_task_queue_wakeup to wakeup the
1623 scheduler by the specified task queue. Affected file
1624 lib/silcutil/silctask.[ch].
1626 * The silc_socket_host_lookup_start now wakes up the scheduler
1627 after adding the timeout task. Affected file is
1628 lib/silcutil/silcsockconn.c.
1630 * The silc_socket_host_lookup is synchronous now if the threads
1631 support is not compiled in. However, the callback is still
1632 called asyncronously through the scheduler, anyway. Affected
1633 file lib/silcutil/silcsockconn.c.
1635 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Added new function silc_socket_host_lookup to perform
1638 asynchronous IP and FQDN lookups for the socket connection.
1639 Affected files lib/silcutil/silcsockconn.[ch].
1641 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1644 that may or may not compile the mutex support in.
1646 Changed the silc_mutex_alloc interface. It allocates the
1647 mutex now to the sent pointer and returns TRUE or FALSE.
1649 Affected file lib/silcutil/silcmutex.h.
1651 * Wrote the SILC Task Queue interface to support multi-threads.
1652 Affected file lib/silcutil/silctask.[ch].
1654 * Wrote the SILC Scheduler to support multi-threads. Affected
1655 file lib/silcutil/silcschedule.c.
1657 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1660 in lib/silcutil/win32/.
1662 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * Defined SILC Mutex API and SILC Thread API and implemented
1665 them for Unix. Affected files are
1666 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1667 lib/silcutil/unix/silcunixmutex.c and
1668 lib/silcutil/unix/silcunixthread.c.
1670 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * Fixed the silc_server_remove_clients_by_server's channel
1673 key re-generation. The hash table handling was incorrect
1674 and would not work with many channels. Affected file is
1677 * Fixed some memory leaks around the server code.
1679 * Rewrote the silc_server_get_users_on_channel to support IPv6
1680 based Client ID's. Affected file silcd/server.c.
1682 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1683 specification. However, a separate document must be written
1684 to define the detailed signing procedure and the payload
1685 associated with the flag. Defined the flag to the
1686 lib/silccore/silcchannel.h as well.
1688 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Changed the dynamic tables to static size tables in the
1691 lib/silccrypt/silchmac.c.
1693 * Removed GCC dependencies from the code. A patch by cras.
1695 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Do not show the error "Error receiving packet bla bla"
1698 in server if it really was not an error (-2 means that reading
1699 is pending). Affected file silcd/server.c.
1701 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Fixed a possible crash in silc_server_remove_clients_by_server
1704 in silcd/server.c. Fixed there also some memory leaks.
1706 * Fixed the silc_idlist_replace_client_id. It could replace
1707 wrong key in the hash table. Affected file silcd/idlist.c.
1709 * Do not check whether there are global users on the channel
1710 if the channel->global_users is FALSE. Affected functions
1711 silc_server_remove_from_one_channel and
1712 silc_server_remove_from_channels in silcd/server.c. Also,
1713 do not check if the removed client is local as we can be
1714 sure that global client was not removed from the channel
1715 and checking for global users is not needed.
1717 * The silc_server_remove_clients_by_server now re-generates
1718 the channel keys correctly for those channels that had
1719 clients removed from them. Affected file silcd/server.c.
1721 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * Found the reason of random crashes in the server. We weren't
1724 ignoring the SIGPIPE signal (which can be sent in write())
1725 and it crashed the server. Affected file silcd/silcd.c.
1727 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Assure that sock->user_data is not NULL in the function
1730 silc_server_packet_send in silcd/packet_send.c.
1732 * Disconnect the remote connection if it could not be added
1733 to any ID lists in the server. The affected file is
1736 * Check in silc_server_packet_send[_real/dest] that the
1737 socket is not disconnecting and ignore the data if it is.
1738 Affected file silcd/packet_send.c.
1740 * Define inline to __inline on native WIN32 compilation.
1741 Affected file includes/silcwin32.h.
1743 * Added some explicit type casts for inline code since MSVC
1744 require them. Affected files lib/silcutil/silcbuffer.h,
1745 lib/trq/silcdlist.h and lib/trq/silclist.h.
1747 * Print warning in log files from now on if the packet
1748 decryption fails. Affected file silcd/server.c.
1750 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Changed the `say' client operation's interface to accept
1753 new `type' argument to indicate the type of the message sent
1754 by the library. The application may filter the library's
1755 messages according the type. The affected file is the
1756 lib/silcclient/silcapi.h.
1758 * Added two new functions to lib/silcclient/silcapi.h:
1759 silc_client_del_client and silc_client_del_client_by_id.
1760 Affected file lib/silcclient/idlist.c.
1762 * Moved the clientincludes.h from includes/ to silc/ and
1763 serverincludes.h from includes/ to silcd/.
1765 * The modes for the CMODE and CUMODE are now passed as
1766 uint32 for application with COMMAND_REPLY. The affected
1767 file is lib/silcclient/command_reply.c.
1769 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * /WHOIS without arguments shows client's own information.
1772 Affected file lib/silcclient/command.c.
1774 * Changed PING to not accept any arguments. The specs
1775 says that client can ping only the connected server so
1776 requiring an argument is not needed. Affected file is
1777 lib/silcclient/command.c.
1779 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1781 * Fixed a fatal bug in private message sending and reception
1782 encryption and decryption when using private message keys.
1783 The implementation was incorrect and did not follow the
1784 specification. It causd that some of the message were
1785 lost since it did not use the sending and receiving keys
1786 as the protocol suggests. This has been fixed and will cause
1787 incompatibilities with older clients when sending private
1788 message encrypted with private message keys. Affected files
1789 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1790 and various other in Irssi SILC Client.
1792 Added `responder' boolean argument to the functions
1793 silc_client_add_private_message_key[_ske] to indicate when
1794 the key is added as responder or initiator of the key
1797 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Removed the silc_ske_check_version function and created
1800 a SilcSKECheckVersion callback. Added also a function
1801 silc_ske_set_callbacks that is now used to set all SKE
1802 callbacks. The callback functions are not given to
1803 the SKE functions anymore, but this function is used to
1806 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1808 * Added `silc_version' argument to the silc_client_alloc
1809 to define the version of the application for the library.
1810 The library will use the version string to compare it
1811 against the remote host's (usually a server) version
1812 string. Affected file lib/silcclient/silcapi.h
1814 * Added the KE protocol context to Key Agreement context
1815 in client library so that we can abort the SKE if it
1816 is in process when we get timeout. Affected file is
1817 lib/silcclient/client_keyagr.c.
1819 * Do not resolve the client ID forever if it returns in the
1820 first time that such client does not exist. This was done
1821 for example with private message. Affected file is
1822 lib/silcclient/client_prvmsg.c.
1824 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Do not add regex.h for WIN32. The affected file
1827 includes/silcincludes.h.
1829 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1830 not work yet 100%. It generates the DLL's automatically
1831 when compiling with --with-win32 under cygwin.
1833 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * lib/contrib/regex.c is not compiled on WIN32.
1837 * Added silc_net_get_socket_opt function to the
1838 lib/silcutil/silcnet.h.
1840 * Added includes/silcwin32.h for WIN32 specific includes
1843 * Do not use ptime structure or any of the posix process
1844 functions on WIN32 in lib/silccrypt/silrng.c.
1846 * Added silc_gettimeofday to provide generic function
1847 for struct timeval on all platforms. Added the function
1848 to lib/silcutil/silcutil.h.
1850 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1853 library as they clearly belong there. As a plus side we
1854 can make the actual socket connection routines platform
1857 Added also new generic function silc_socket_read and
1858 silc_socket_write (that used to be silc_packet_[read/write].
1859 The implementation of these are platform specific.
1861 * Added WIN32 specific routines of silc_socket_[read/write]
1862 to lib/silcutil/win32/silcwin32sockconn.c.
1864 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Added preliminary support for native WIN32 compilation under
1867 cygwin (using the -mno-cygwin option for GCC) to the
1868 ./configure.in.pre. The --with-win32 now prepares the
1869 compilation for native WIN32.
1871 * Rewrote the SILC Scheduler interface in the file
1872 lib/silcutil/silcschedule.h. The scheduler is now context
1873 based and does not have anymore any global static scheduler.
1874 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1875 and created lib/silcutil/win32 directory for WIN32 based
1878 * Added Unix specific network routines to the
1879 lib/silcutil/unix/silcunixnet.c and the old
1880 lib/silcutil/silcnet.c includes now only generic routines.
1882 Added WIN32 specific network routines to the
1883 lib/silcutil/win32/silcwin32net.c.
1885 * Added Unix specific utility functions from the
1886 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1888 * Added WIN32 SILC Scheduler to the file
1889 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1892 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Do not handle JOIN notify in the server if the target client
1895 is not registered (idata->registered == FALSE). The affected
1896 file is silcd/packet_receive.c.
1898 * Update the nickrec->founder in event_cumode in the Irssi SILC
1899 client. Affected file irssi/src/silc/core/silc-channels.c.
1901 * Fixed the CUMODE_CHANGE notify handling in the server when
1902 server and router are announcing their clients on channels.
1903 Now the mode changes are saved and notified correctly. The
1904 affected file is /silcd/packet_receive.c.
1906 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1907 They really did not replace the cache entry in the ID Cache.
1908 Now they do that. Affected file silcd/idlist.c.
1910 * Fixed the KICK notify handling in the Irssi SILC client to
1911 update the channel records so that the kicked client does not
1912 appear to be on the channel. The affected file is
1913 irssi/src/silc/core/silc-channels.c.
1915 * Always update the conn->current_channel when executing command
1916 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1918 * Fixed the KILL notify handling in Irssi SILC client to remove
1919 the killed client on all channels.
1921 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1923 * Fixed the silc_parse_command_line to remove extra spaces
1924 from the start and end of the arguments. Affected file is
1925 lib/silcutil/silcutil.c.
1927 * Cancel and free any active protocol in the function
1928 silc_server_close_connection. Affected file silcd/server.c.
1930 * Cancel and free any active protocol in the function
1931 silc_client_close_connction. Affected file is
1932 lib/silcclient/client.c.
1934 * Do not execute the KILL command for clients that are in
1935 history (ie. they are not in the network). Affected file is
1938 * Fixed KILL notify handling, client does not crash anymore.
1939 Affected file irssi/src/silc/core/silc-channels.c.
1941 * Reduced the default packet buffer size from 2048 to 1024 in
1942 lib/silccore/silcpacket.c.
1944 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1945 counter to the SKE context that is incresed when the SKE library
1946 performs async operation outside the library. If the outside
1947 process frees the SKE context and FREED status will be set
1948 and the library will detect after the sync operation that the
1949 libary is freed. The affected files are
1950 lib/silcske/silcske[_status].[ch].
1952 * Resolve the client entry information in the function
1953 silc_client_channel_message to assure that NULL pointer is not
1954 passed as client entry to the application. */
1956 * Fixed the task timeout calculation to assure that there is
1957 never negative timeouts. The affected file is
1958 lib/silcutil/silcschedule.c.
1960 * Fixed the channel user mode notification sending in server.
1961 It was sent point-to-point to the router (or to server by router)
1962 but it needs to be destined to a channel. The routines now
1963 supports sending the channel user mode notifys to the channels
1964 when announcing clients and channels. Affected files are
1965 silcd/server.c and silcd/packet_receive.c.
1967 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1968 It did not actually replace the old channel entry in the cache.
1969 Affected file lib/silcclient/client_notify.c.
1971 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * Fixed a possible crash in silc_packet_send_prepare. It now
1974 assures always that there is enough space in the buffer and
1975 at the tail area of the buffer (for MAC).
1977 Fixed the inbound buffer reallocation in silc_packet_read.
1978 It was old code and did not handle the reallocation correctly.
1981 The affected file is lib/silccore/silcpacket.c.
1983 * Fixed buffer overflow in silc_parse_nickname in the file
1984 lib/silcutil/silcutil.c.
1986 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * make install generates new server keys only if there is not
1991 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1994 Added check that if the NOREPLY is set then we will not send
1995 the away message. This avoids infinite loop of away messages
1996 if both clients are away. The affected file is
1997 lib/silcclient/client_prvmsg.c.
1999 * Fixed client crash if /NICK was given without arguments.
2000 Affected file lib/silcclient/command.c.
2002 * Server does not send the invite list in INVITE command back
2003 to the client if the list was not altered. Added this notion
2004 to the protocol spec as well. Affected file silcd/command.c.
2006 Fixed possible crash in INVITE command by checking the
2007 value of silc_server_get_client_route command.
2009 * Fixed the INVITE notify type handling. The arguments are now
2010 taken in correct order and client does not crash. The affected
2011 file is irssi/src/silc/core/silc-channels.c.
2013 Removed the "Inviting xxx to channel" message from the
2014 client library away and let the application handle it.
2015 Affected file lib/silcclient/command.c. Added that message
2016 to Irssi SILC client's message formats.
2018 * Fixed CMODE command crash in client. It now checks the
2019 amount of arguments correctly and does not crash. The affected
2020 file is lib/silcclient/command.c.
2022 * Do not create new channel automatically in silc_channels_join
2023 but check whether the channel by that name already exists.
2024 Affected file irssi/silc/core/silc-channels.c.
2026 * Do not send the SERVER_SIGNOFF to router if the disconnected
2027 entity was the router. Affected file silcd/server.c.
2029 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2030 SILC client as it was missing from there.
2032 Added the handling of the KICK notify to the Irssi SILC client
2033 as it was missing. Added "you have been kicked" message to
2034 Irssi SILC client's message modules formats.
2036 Added the handing of the KILL notify to the Irssi SILC client
2037 as it was missing. Added the kill message module formats
2040 The affected file is irssi/src/silc/core/silc-channels.c.
2042 * The router did not save the channel mode the server announced.
2043 Affected file silcd/packet_receive.c.
2045 * Fixed a possible crash in INFO command in server. If the
2046 server did not provide the server info it crashed. Affected
2047 file silcd/command.c.
2049 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2051 * Fixed the GETKEY command in the server to check also the
2052 global list. Otherwise the GETKEY would not work correctly
2053 in normal SILC server. Affected file silcd/command.c.
2055 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Fixed GETKEY crash, it crashed if the command did not succseed.
2059 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2062 is now real and not just an macro interface to GMP.
2064 Removed the entire GMP from the source tree and imported new
2065 NSS MPI library instead. Reason for removing GMP is that it is
2066 extremely large and compiles extremely slow. The NSS MPI
2067 is only a few files and compiles in less than 10 seconds.
2068 The speed is also about the same as GMP. The MPI is imported
2069 to lib/silcmath/mpi.
2071 If the system has GMP installed we will still use the GMP.
2072 If it is not then the NSS MPI will be compiled.
2074 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Merged a long nickname (127 characters long) crash bugfix from
2077 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2079 * Merged a freed memory reference bugfix from Irssi CVS tree.
2080 Affected file irssi/src/core/commands.c.
2082 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added the server's public key sving and verification to the
2085 server when performing the SKE. This was missing and the
2086 remote server's (or router's) public key was accepted without
2087 checking whether we have it previously or trust it at all.
2088 Affected file silcd/protocol.c.
2090 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Check in the silc_server_timeout_remote if protocol is active
2093 and make sure that the protocol's final callback is called so
2094 that all memory if freed. Affected file silcd/server.c.
2096 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * silc_server_whois_send_reply crashed the server if the nickname
2099 was 127 characters long. Affected file silcd/command.c.
2101 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Added sanity check to the silc_server_new_client. If the hostname
2104 is provided inside username then check that the provided hostname
2105 really is the same as the resolved one. If the hostname was not
2106 resolved then check it from the public key. Affected file is
2107 silcd/packet_receive.c.
2109 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2110 if the server disconnected us and the connection is not valid
2111 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2113 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2114 the library to the lib/silcutil/silcutil.[ch].
2116 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Close log file after open. Affected file
2119 lib/silcutil/silclog.c.
2121 * Check whether sock == NULL in silc_client_send_packet and return
2122 if it is. Affected file lib/silcclient/silcclient.c.
2124 * Check rec->entry == NULL in the Irssi SILC Client before
2125 sending the channel message. Affecte file is
2126 irssi/src/silc/core/silc-servers.c.
2128 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Merged a splitted window bugfix from Irssi CVS tree. The
2131 affected file is irssi/src/fe-text/textbuffer-view.c.
2133 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2134 It did not print nickname.
2136 * Improved the distributions system a bit.
2138 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2141 irssi/src/fe-text/gui-window.c.
2143 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2144 to in-active server. The affected file is
2145 irssi/src/silc/core/client_ops.c.
2147 * Resolve the client in USERS command reply if the entry does
2148 not have username resolved. The affected file is
2149 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2150 command to WHOIS command to really resolve stuff. The USERS
2151 is not used any more in any critical section so WHOIS can
2152 be used even though it might be slower than IDENTIFY.
2154 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2157 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2159 * Changed the protocol API a bit more consistent in the
2160 lib/silccore/silcprotocol.[ch].
2162 * Changed the following headers to ROBODoc format:
2164 lib/silccore/silcpayload.h
2165 lib/silccore/silcprotocol.h
2166 lib/silccore/silcsockconn.h
2168 All core library headers are now formatted.
2170 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Fixed a bug in Irssi SILC client; do not show that you are
2173 server/router operator if you really are not. Affected file is
2174 irssi/src/silc/core/client_ops.c.
2176 * Renamed silc_command_free_payload to silc_command_payload_free.
2177 Affected file lib/silccore/silccommand.h
2179 * Added silcmath.h to include the prototoypes of various routines
2180 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2183 * Changed the following headers to ROBODoc format:
2185 lib/silccore/silcchannel.h
2186 lib/silccore/silccommand.h
2187 lib/silccore/silcid.h
2188 lib/silccore/silcidcache.h
2189 lib/silccore/silcmode.h
2190 lib/silccore/silcnotify.h
2191 lib/silccore/silcpacket.h
2192 lib/silcmath/silcmath.h
2194 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * Added checking to the server code not to start the server if
2197 ciphers and stuff are not configured properly. Affected files
2198 silcd/serverconfig.[h] and silcd/server.c.
2200 * Changed the layout of the header files of the public interfaces
2201 in the SILC libraries. The new layout supports ROBODoc
2202 documentation tool (and some others) so that it is easy to create
2203 a library reference manual. All the other headers and source
2204 code must still follow the CodingStyle document. Also source
2205 code must not include these ROBODoc stuffs, only the headers.
2206 Furthermore, all public interface headers must now be named
2207 by using `silc' prefix, example: silcapi.h, silccipher.h.
2208 Some files were renamed due to this. All the other headers
2209 must not be used as public interfaces. I will update the
2210 CodingStyle document later. Changed following headers, so far:
2212 lib/silcclient/silcapi.h
2213 lib/silccore/silcauth.h
2214 lib/silccore/silcprivate.h
2215 lib/silccrypt/silcdh.h
2217 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Removed silc_client_packet_send_flush from the client library
2222 as it is not needed. Affected file lib/silcclient/client.[ch].
2224 * Added printing of message of unresolved authentication method
2225 to the Irssi SILC client. Added it to the module formats.
2226 Removed the same message from the client library.
2228 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Added new distribution feature, DISTLABEL. Every distribution
2231 can define own preprocessor label that can be used in the
2232 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2233 file distributions, acconfig.h.pre and prepare.
2235 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Added Makefile.defines_int to include the actual definitions
2238 for Makefile.defines.in. Tested the new distribution system,
2239 created distributions and tested installation.
2241 * Added AWAY message printing to the Irssi SILC client. Added
2242 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2244 * Added SCONNECT command to call the SILC's CONNECT command.
2245 Cannot use CONNECT directly since Irssi uses that internally.
2246 Affected file irssi/src/silc/core/silc-servers.c.
2248 Added ACTION local command. It is same as ME command but takes
2249 the channel as mandatory argument.
2251 Rewrote some of the Irssi's help files to suite for SILC
2254 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Added Makefile.defines[.in] that should for now on be included
2257 in all Makefile.am file in the source tree. That file includes
2258 all common compilation definitions for SILC source tree.
2260 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Minor changes to the ./prepare script to change the package
2263 name according the distribution name to the configure.in.
2265 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Created new distribution system. Added file `distributions'
2268 that defines all the distributions that can be created out of
2269 the SILC source tree. The ./prepare script now reads that
2270 file to determine how to prepare the distributions. The
2271 first argument to the ./prepare is the name of the distribution
2272 and second is the version of the distribution. If given
2273 without arguments it creates the default (toolkit) distribution
2274 with the default version (defined in ./prepare).
2276 All Makefile.am files that are subject to the distributions
2277 are now named as Makefile.am.pre. These are ./Makefile.am
2278 and lib/Makefile.am. Others may be changed later.
2280 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Added invite list, ban list, some key management and connection
2283 error message printing to module formats in the Irssi SILC client.
2285 * Added new silc_client_set_away_message to set the away message
2286 that is back to the person who sent private message. The
2287 affected file lib/silcclient/silcapi.h and the
2288 lib/silcclient/client_prvmsg.c.
2290 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Fixed the private message sending in the Irssi SILC client,
2293 added local command KEY to the Irssi SILC client.
2295 Added key management and key agreement message formats to the
2296 irssi/src/fe-common/silc/module-formats.[ch].
2298 Added USERS (alias WHO) printing, server/router operator
2299 indication and LIST command printing to the module formats.
2301 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Fixed channel joining notify handling, cumode notify handling
2304 from Irssi SILC client.
2306 * Added SILC specific module-formats to the Irssi SILC client so
2307 that SILC specific message hilighting, colors etc is possible.
2308 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2310 Added channel mode, channel user mode, actions, notices,
2311 whois and whowas printing to the the module-formats.c.
2313 * Fixed a bug in channel deletion in the server. The channel
2314 is not left to the cache even if the channel founder auth mode
2315 is set when there are no users anymore on the channel. Affected
2316 file silcd/server.c.
2318 * The silc_net_localhost now resolves the entire hostname including
2319 the domain name. Affected file lib/silcutil/silcnet.c.
2321 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Changed the ask_passphrase client operation to be ascynchronous.
2324 It has now a completion callback and a context that the
2325 application must call after it has got the passphrase from
2326 the user. Affected files lib/silcclient/silcapi.h,
2327 lib/silcclient/protocol.c, lib/silcclient/command.c and
2330 Added SilcAskPassphrase callback that the application calls
2331 to deliver the passphrase to the library.
2333 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2334 The public key verification and especially a certificate
2335 verification is asynchronous procedure.
2337 Added new SILC_SKE_STATUS_PENDING status to indicate the
2338 request is pending and a callback will be called to finalize
2341 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2342 indicate that remote end did not send its public key (or
2343 certificate), even though we require it. Added check for this
2344 condition in the SKE. This was a security bug, now fixed.
2346 Defined new SilcSKEVerifyCbCompletion callback that is called
2347 when the verification process is completed.
2349 The affected files lib/silcske/silcske_status.h and
2350 lib/silcske/silcske.[ch].
2352 * Changed the verify_public_key client operation to be async
2353 as well. Defined SilcVerifyPublicKey callback that is used to
2354 indicate the success of the public key verification process.
2356 Changed the server and client to use the new async client
2359 * Changed the Irssi SILC client's internal scheduler to be called
2360 twice as many times as it used to be. As a result the client
2361 should be a bit faster now. Affected file is
2362 irssi/src/silc/core/silc-core.c.
2364 * Added support to Irssi SILC client of asynchronous public key
2365 verification and passphrase inquiry. Affected file is
2366 irssi/src/silc/core/silc-core.c.
2368 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Do not say "You have left channel %s" in client library.
2371 Moved it to the application. Affected files are
2372 lib/silcclient/command.c and silc/client_ops.c.
2374 * Fixed silc_client_get_clients. Command context was not
2375 duplicated and was freed memory in the callback. Affected
2376 file lib/silcclient/idlist.c.
2378 * Do not say "you are now talking..." on JOIN command in the
2379 client library. The appliation must handle it.
2381 * Do not say ".. changed topic to" in command reply in the
2382 client libary. The application must handle it.
2384 * Fixed TOPIC command sending in the client library.
2386 * Fixed a memory leak in silc_client_command_free in the file
2387 lib/silcclient/command.c.
2389 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Imported a modified version of Irssi client to the source tree.
2392 The Irssi will be used to create a new client called
2393 Irssi SILC. Imported to irssi/.
2395 Added silc_core_init_finish function to the Irssi. Affected
2396 file irssi/configure.in.
2398 A lot changes in the Makefile.ams around the irssi tree.
2400 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Do not rehash if the new size is same as the old size of the
2403 hash table, in the silc_hash_table_rehash*. The affected file
2404 lib/silcutil/silchashtable.c.
2406 * Replaced hash_table_del_by_context calls from the server
2407 (when channel->user_list and client->channels) to the
2408 hash_table_del as it is sufficient and faster.
2410 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Added silc_hash_table_list, silc_hash_table_get and the
2413 SilcHashTableList structure to provide an alternative way to
2414 traverse the hash table. The affected files are
2415 lib/silcutil/silchashtable.[ch].
2417 * Changed the server's idlist routines to use the hash table
2418 routines to optimize the code.
2420 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Replaced the client entry's `channel' list and channel entry's
2423 `user_list' list to hash tables for optimized lookup. Changed
2424 the code to use the hash table interface around the code.
2425 Affected file lib/silcd/idlist.[ch].
2427 * Added `auto_rehash' boolean argument to the function
2428 silc_hash_table_alloc to indicate whether the hash table should
2429 auto-rehash when it thinks is appropriate time. It will
2430 increase the hash table size if the there is twice as much
2431 entries in the table than the size of the table, and will
2432 decrease the size if there are twice as less entries than
2433 the size of the table.
2435 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2439 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * silc_idcache_purge_by_context deletes the entry now by context
2442 as it is supposed to do. Affected file lib/silccore/idcache.c.
2444 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2445 client is not anymore valid (WHOWAS givens the info) and not
2446 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2448 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Removed the `data' and `data_len' arguments from the ID Cache
2451 interfaces and added `name' argument. ID Cache does not handle
2452 anymore the binary data only a names associated with given ID.
2454 * When hashing a Client ID with silc_hash_id the entire ID is
2455 not hashed anymore, instead only the hash of the Client ID is
2456 hashed. This way we can access the Client ID from the cache
2457 with Client ID but with the hash of the ID (which is a hash of
2458 the nickname) as well without any difference in performance.
2460 Added also silc_idcache_find_by_id_one_ext to do one on one
2461 searching when we have the actual ID. Added also function
2462 silc_hash_client_id_compare. The affected files are
2463 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2465 * When hashing the name associated with a ID it is always done
2466 in lowercase. This way we can access the cache without worrying
2467 about case-sensitivity, even though, for example nicknames are
2470 * Fixed a bug in server with channel message sending. It put
2471 wrong ID type as destination ID. The affected file
2472 silcd/packet_send.c.
2474 * silc_idcache_del_by_context now deletes from all hash tables
2475 by context. Affected file lib/silccore/idcache.c.
2477 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Changed the client library to use the new ID Cache interface.
2480 Changes around the source tree.
2482 * Added silc_hash_table_rehash_ext to rehash with specific
2483 hash function. Affected file lib/silcutil/silchashtable.[ch].
2485 * Added silc_hash_string_compare to compare two strings in the
2486 hash table. Affected file lib/silcutil/silcutil.[ch].
2488 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Added new function silc_idcache_del_by_context into the
2491 lib/silccore/idcache.[ch].
2493 * Changed the server's ID list routines to use the new ID Cache
2494 interface. Changes around the source tree.
2496 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Added silc_hash_table_del[_by_context]_ext functions in to the
2499 lib/silcutil/silchashtable.[ch].
2501 Removed silc_hash_table_find_all* routines and added new
2502 silc_hash_table_find_foreach to replace them.
2504 Added silc_hash_table_replace_ext function as extended
2505 replacing function. Separated the simple hash table interface
2506 from the extended hash table interface in the file
2507 lib/silcutil/silchashtable.h.
2509 * Fixed minor bugs and changed it to use some of the new
2510 hash table functions in lib/silccore/idcache.c
2512 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added new function silc_hash_table_find_all to return all keys
2515 in the hash table by the specified key. As the hash table is
2516 collision resistant it also makes it possible to have several
2517 duplicate keys in the hash table. This function may be used to
2518 find all of the keys from the hash.
2520 Added user_context arguments to the SilcHashFunction,
2521 SilcHashCompare and SilcHashDestructor to deliver user specified
2524 Added new fuctions silc_hash_table_find[_all]_ext to do
2525 extended lookup with specified hash and compare functions and
2526 specified user contexts.
2528 Added new function silc_hash_table_add_ext to add the key
2529 with specified hash function and user context.
2531 Added new function silc_hash_table_foreach to traverse all
2532 entrys in the hash table. Added SilcHashForeach callback
2535 Added new function silc_hash_table_del_by_context to delete
2536 the entry only if the context associated with the key matches.
2538 Affected files are lib/silcutil/silchashtable.[ch].
2540 * Removed silc_hash_[server/client/channel]_id and added just
2541 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2542 silc_hash_id_compare to compare two ID's using as the hash table
2543 comparison function. Added also silc_hash_data to hash
2544 binary data and silc_hash_data_compare to compare it.
2546 * Removed silc_idlist_find_client_by_hash as it is not needed
2547 anymore. Affected file silcd/idlist.[ch].
2549 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2550 to use internally the SilcHashTable. The new ID Cache is a lot
2551 faster than the old one. Some of the ID Cache interface was also
2552 rewritten and obsolete and stupid functions were removed.
2554 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Added entry_count field to the SilcHashTable to keep the number
2557 of the entries in the table. Implemented the function
2558 silc_hash_table_rehash. Added new function
2559 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2561 Fixed a minor bug in silc_hash_table_free.
2563 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2564 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2565 into the lib/silcutil/silcutil.[ch].
2567 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Implemented a collision resistant hash table into the
2570 lib/silcutil/silchashtable[ch]. See the header and the source
2571 for the SilcHashTable API.
2573 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Merged dotconf version 1.0.2 into lib/dotconf.
2577 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Do not compile anything in lib/silcsim/* if the SIM support
2580 is not enabled. The tree should now compile without problems
2583 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Compiled the SILC under cygwin. Compiled and tested briefly
2586 without problems. More tests needed. The SIMs didn't compile
2589 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2591 * Fixed possible crash in silc_get_username in the
2592 lib/silcutil/silcutil.c.
2594 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Fixed a va_arg in silc/client_ops.c.
2598 * Oops, RC5 routines were named AES and caused some problems
2599 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2601 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Added new SilcIDIP structure into the lib/silccore/id.h and
2604 replaced the old `ip' fields from all SILC ID's to that type.
2605 This is a step towards IPv6 support.
2607 The silc_id_get_len takes now the ID as an extra argument.
2608 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2609 both IPv4 and IPv6 based ID's.
2611 The affected files are lib/silccore/id.[ch] and other files
2612 around the tree using these routines.
2614 * Removed the ID length arguments in server from various
2615 silc_server_send_notify_* routines -> they are not needed
2618 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Fixed memory leak in silc_encode_pem_file in the file
2621 lib/silcutil/silcutil.c.
2623 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Check minor version as well in the SKE. Affected files are
2626 silcd/protocol.c and lib/silcclient/protocol.c.
2628 * Added --identifier option to the server so that an identifier
2629 can be when creating the public key for the server. Affected
2630 file is silcd/silcd.c.
2632 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2633 lib/silccrypt/silcpkcs.c.
2635 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Register default ciphers and stuff when using -C option with
2638 the server. Affected file sildc/silcd.c.
2640 * Put back the servers public key filename format, it is better
2641 than the new one. For now, the client keys are saved with the
2642 new filename format. The affected file silc/client_ops.c.
2644 * Implemented the Cipher API for the rest of the ciphers that
2645 did not implement it or implemented it the wrong way.
2647 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Register default ciphers and stuff when using the -S option
2650 in the client. Affected file silc/silc.c. Same also when
2651 creating new key pair with -C option.
2653 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Fixed the silc_verify_public_key client operation function to
2656 save the public keys differently. The fingerprint is now
2657 used as filename and not the hostname. This way also the
2658 client keys are saved uniquely and not with hostnames. The
2659 affected file is silc/client_ops.c.
2661 * Trimmed the silc_hash_fingerprint function to remove extra
2662 whitespaces from the end of the fingerprint. The affected
2663 file is lib/silccrypt/silchash.c.
2667 * Added silc_cipher_register_default function to register all
2668 default ciphers. It can be used when configuration files
2669 does not exist and the application does not want any specific
2670 ciphers in any specific order.
2672 The SilcDList is now used as silc_cipher_list dynamically
2673 allocated cipher list. Removed the static list all together
2674 and now all ciphers must be allocated to the dynamic list.
2675 The silc_cipher_alloc routine was changed to check only the
2678 All silc_cipher_* routines that used to return int returns
2681 The affected files lib/silccrypt/silccrypt.[ch].
2683 * The same thing was done to silc_hash_* as for silc_cipher_*
2684 routines. Affected files lib/silccrypt/silchash.[ch].
2686 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2687 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2688 Added also silc_pkcs_[un]register[_default] functions.
2689 Removed the data_context from the PKCS API.
2691 * Added silc_hmac_register_default function to register default
2692 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2693 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2694 to unregister all hmacs at once.
2696 * Register the default ciphers, hash functions, PKCSs and HMACs
2697 if client's configuration file does not exist. The affected
2700 * The client did not load the hash functions from the SIM
2701 modules at all. Added support for this. Affected file is
2702 silc/clientconfig.c.
2704 * When decoding public key with silc_pkcs_public_key_decode, check
2705 the supported algorithm only if PKCS are registered. Affected
2706 file lib/silccrypt/silcpkcs.c. The same was done with the
2707 silc_pkcs_private_key_decode.
2709 * Fixed the SILC List routines to keep the list always in order.
2710 It used to change the list's order when traversing the list but
2711 not it preserves the order. Affected file lib/trq/silclist.h.
2713 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Added the client library to use the SilcSocketConnection's
2716 reference counter (by silc_socket_dup) to prevent the bug that
2717 the socket object may be freed underneath async operation.
2719 * The name resolv library checking fixes in the configure.in.pre.
2722 * Created new version of the protocol drafts for future
2723 development. The -03 drafts are the ones that will be changed
2724 in the trunk now and the -02 will remain as they are.
2726 * Send list of CUMODE notifys to the router when announcing
2727 the channel users to the router. Affected file silcd/server.c.
2728 If the router receiving channel founder CUMODE for a channel
2729 that already has channel founder it will send CUMODE notify
2730 to the sender to remove the channel founder rights from the
2731 announced client. Affected file silcd/packet_receive.c.
2733 * The CUMODE notify may now use Server ID as well as the entity
2734 who changes the mode. Updated protocool specs.
2736 * Updated INSTALL and README files.
2738 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * New web pages in the http://silc.pspt.fi. The pages was
2745 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Implemented the [DenyConnectin] config section in the server.
2748 Added silc_server_config_denied_conn to check whether incoming
2749 connection is denied. Affected file silcd/serverconfig.[ch].
2751 * Do not check the ports when checking the incoming configuration
2752 data if the port is 0, meaning any. Affected file is
2753 silcd/serverconfig.c.
2755 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Fixed buffer overflow in silc_string_compare in the file
2758 lib/silcutil/silcutil.c.
2760 * Fixed double free in silc_server_command_leave in the file
2763 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * Fixed the version checking in the server. Affected file is
2768 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Fixed the configuration data fetching when accepting new
2771 connections in the server. Affected file silcd/server.c.
2773 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Added `sender_entry' argument to the function
2776 silc_server_packet_relay_to_channel so that we can check
2777 whether some destination actually belongs to the same route
2778 the sender belongs (ie, we must not resend the packet to the
2779 sender). Affected file silcd/packet_send.[ch].
2781 * Added `servername' field to the SilcClientEntry in the server
2782 to hold the name of the server where client is from. Affected
2783 file is silcd/idlist.h.
2785 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Moved the channel message encrypting in the router betwen
2788 router connections from silc_server_channel_message to the
2789 silc_server_packet_relay_to_channel since we want to check
2790 whether we have anybody channel before encrypting anything.
2791 Affected files silcd/packet_[receive/send].c.
2793 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Fixed the [AdminConnection] server config section to support
2796 multiple entries. Affected file silcd/serverconfig.c.
2798 * Added support into the server to check the validity of the
2799 incoming connection before executing any KE or authentication
2802 * The connection configuration is now saved to the KE and
2803 connection auth protocol contexts and not fetched anymore in
2804 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2806 * The local hosts listenning address and port is also resolved
2807 now when starting the server. We want to have the socket object
2808 to include the real address and port for the listener. Added
2809 new function silc_net_check_local_by_sock into the files
2810 lib/silcutil/silcnet.[ch].
2812 * Fixed a broadcast bug in server -> do not broadcast if we
2815 * Fixed a routing bug. Do not route broadcast packets ever.
2816 Broadcast packets must be processed always and not routed since
2817 they may be destined to some other host than yourself and thus
2818 would get routed without no good reason. Affected file is
2821 * Added function silc_server_config_is_primary_route to check
2822 whether primary router connection has been configured (a router
2823 configuration that we are initiating). If there is not, we
2824 will assume that there is only two routers in the SILC network
2825 and we will use the incoming router connection as our primary
2826 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2828 * Changed the order of the broadcasting. Broadcast _after_ the
2829 packet has been processed not before. Affected file is
2832 * Fixed a [ClientConnection] parsing bug. The port was never
2833 parsed correctly thus resulting to port 0. Affected file
2834 silcd/serverconfig.c.
2836 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2837 argument and did not set the broadcast packet flag. Affected
2838 file silcd/packet_send.c. Fixed same bug in the function
2839 silc_server_send_notify as well.
2841 * If we receive NEW_ID packet for our own ID in the server, ignore
2844 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Removed the nickname from the Private Message Payload.
2849 Updated the code and the protocol specs.
2851 * Updated protocol specs for submitting to the IETF.
2853 * Tweaked the Random Number Generator a bit. Affected file
2854 lib/silccrypt/silcrng.c. Exported a new function
2855 silc_rng_[global]_add_noise which can be used to add more
2858 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Do not parse packets with different timeout when protocol
2861 is active -> may cause problem with rekey. Affected file
2864 * When server receives signoff notify it must not create
2865 new channel key if the client is on any channels since the
2866 sender of the signoff notify will create it.
2868 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Added printing of error messages during SKE protocol from the
2871 failure packet sent by server during SKE. Affected file
2874 * Removed the client's failure_callback handling with timeout
2875 and handle it immediately when received.
2877 * The SKE library returned wrong type in SUCCESS and FAILURE
2878 packets. They must be 32 bit MSB not 16 bit MSB.
2880 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2882 * Ok, rewrote the logic of the re-key and now it seems to work.
2883 I tested it on high traffic with frequent re-keys without
2884 problems. Added hmac_receive (and renamed hmac to hmac_send)
2885 in SilcClientConnection in lib/silcclient/client.h and
2886 in SilcIDListData in silcd/idlist.h. Also, removed the
2887 SilcPacketParserContext's cipher and hmac fields as they are
2888 not needed anymore and actually caused some problems when
2889 the ciphers and hmac's changed underneath the packet parser.
2891 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * If re-key protocol is active then process the incoming packets
2894 synchronously since we must assure that icoming packets encrypted
2895 with the old key is processed before the new keys is set to
2896 use. This is true other packets than for REKEY packets.
2897 Affected file silcd/server.c. The same was done to client library
2898 as well, affected file lib/silcclient/client.c.
2900 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Fixed bug in client and server to accept the force send if
2903 the packet is send from silc_[server/client]_packet_process
2904 function. Otherwise the packets are never delivered, oops.
2906 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Disable force sending of packets when REKEY protocol is active.
2909 We must assure that no packet is sent directly when rekey is
2910 performed. All packets must be sent through packet queue.
2911 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2912 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2913 function is silc_[server/client]_packet_send_real to check
2916 * Replaced the SIM paths from example config files to
2917 /usr/local/modules. Also, make install creates now
2918 /usr/local/silc/logs directory to hold all the SILC server
2921 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Made the configure.in.pre work on Solaris. Patch by salo.
2925 * Made all ciphers compatible with non-x86 machines. Defined
2926 CBC mode macros into lib/silccrypt/ciphers_def.h.
2928 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Fixed the make install.
2932 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * When MAC computation fails the silc_packet_decrypt returned 0
2935 even though it was supposed to return -1. Fixed this. The
2936 affected file is lib/silccore/silcpacket.c.
2938 * Do not replace the config files in /etc/silc (in make install)
2939 if they already exist. Affected file ./Makefile.am.
2941 * Do not send re-key packets immediately but through packet queue.
2942 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2944 * Changed silc_net_check_host_by_sock to return FALSE if the
2945 IP/DNS could not be resolved. Though, it returns the IP address
2946 now even if it could not resolve it (but returns also FALSE).
2947 Affected file lib/silcutil/silcnet.[ch].
2949 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Added silc_pkcs_decode_identifier to decode the public key's
2952 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2953 Added also silc_pkcs_free_identifier. Added also new context
2954 SilcPublicKeyIdentifier.
2956 * Added -S option to the silc client. It is used to dump the
2957 contents of the specified public key file.
2959 * Changed the PKCS api to return the public key length when
2960 setting the public key.
2962 * Fixed a fatal bug in the public and private key file loading.
2963 Affected file lib/silccrypt/silcpkcs.c.
2965 * Execute the packet parsing for client with zero (0) timeout
2966 if the protocol is active. Affected file silcd/server.c.
2968 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Made the key generation options to the silcd program. Added
2971 -C option, equivalent to client's option.
2973 * Added new [ServerKeys] config section to the server. It
2974 configures the server's public and private key.
2976 * Defined generic Public Key Payload into the protocol
2977 specification to send specific type of public keys and
2980 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2981 public key or certificate.
2983 * Implemented the GETKEY command to the server and to the
2984 client library and on user interface.
2986 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Made preliminary `make install' work.
2990 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added SilcServerRekey context into silcd/idlist.h.
2994 * Added the PFS support as defined in the specification to the
2995 SKE protocol. Affected files lib/silcske/*.c.
2997 * Added `ske_group' field to the SilcServerRekey context to hold
2998 the number of the SKE group that is used with PFS in re-key.
2999 Affected file silcd/idlist.h.
3001 * Added PFS re-key support to the server. Affected file is
3004 * Added silc_protocol_cancel to cancel execution of the next
3005 state of the protocol. Affected file is
3006 lib/silccore/silcprotocol.[ch].
3008 * Added the re-key support with and without PFS to the client
3009 library. Re-key is performed once in an hour, by default.
3011 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3012 Added silc_client_rekey_callback and silc_client_rekey_final.
3013 Affected files are lib/silcclient/protocol.[ch] and
3014 lib/silcclient/client.[ch].
3016 * Removed the `hmac_key' and `hmac_key_len' fields from the
3017 SilcClientConnection structure; not needed. Affected file is
3018 lib/silcclient/client.h.
3022 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Do not ask whether user wants to use the negotiated private key
3025 for private messages, just use it. Affected file is
3026 silc/local_command.c.
3028 * Added `send_enc_key' and `enc_key_len' fields to the
3029 SilcIDListData structure since they are needed in the re-key
3030 phase. Affected file is silcd/idlist.[ch].
3032 * Implemented the simple re-key protocol into the server.
3033 Affected files silcd/server.c and silcd/protocol.[ch]. The
3034 re-key will be performed once in an hour, by default.
3036 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3037 Added silc_server_rekey, silc_server_rekey_callback and
3038 silc_server_rekey_final.
3040 * Removed Tunneled flag from the protocol. Updated the code
3041 and the specifications.
3043 * Adde `pfs' field to the SilcIDListData to indicate whether
3044 the PFS is to be performed in the re-key. Affected file is
3047 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3050 int64 of at least the xintXX size. If void * is less that 4
3051 bytes uint32 * will be used. Defined bool as boolean.
3053 * Changed _ALL_ unsigned long and unsigned int to uint32,
3054 unsgined short to uint16 in the source tree.
3056 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3057 not handle clients that has entry->data.registered == FALSE.
3058 They are not in the network anymore. Affected file is
3061 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Implemented the sending of the SERVER_SIGNOFF notify in the
3064 server. Affected file is silcd/server.c.
3066 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3067 Added also silc_notify_payload_encode_args into the
3068 lib/silccore/silcnotify.[ch].
3070 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3071 Affected file silcd/packet_receive.c.
3073 * Implemented the SERVER_SIGNOFF notify handling in the client
3074 library. Affected file lib/silcclient/client_notify.c. Also,
3075 implemnted the printing of the SERVER_SIGNOFF info to the
3076 application. Affected file silc/client_ops.c.
3078 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3079 if the deleting was successful. Affected file silcd/idlist.[ch].
3081 * Added support for public key authentication in the connection
3082 authentication protocol in the client library. Affected file
3083 lib/silcclient/protocol.c.
3085 * Changed the server's silc_idlist_get_clients_by_* interface
3086 to support already allocated array so that new entries may be
3087 added to pre-allocated array. Affected file silcd/idlist.[ch].
3088 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3089 and command replies.
3091 * All command reply functions in the server now calls the
3092 pending command callback even if error occured. This way the
3093 error will be delivered to the client as well. Affected files
3094 silcd/command.c and silcd/command_reply.c.
3096 * Fixed INFO command to return local server's info if no server
3097 was provided. Affected file lib/silcclient/command.c.
3099 * Removed RESTART command for good. Updated the code and the
3102 * Rewrote parts of the task system. It is a bit simpler now.
3103 Removed unsued task priorities. The affected files are
3104 lib/silcutil/silctask.[ch].
3106 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Moved the USERS printing from the library to the application.
3109 Affected files lib/silcclient/command.c and silc/client_ops.c.
3111 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Added channel key re-key support. The re-key is perfomed
3116 only by the router and is done once in an hour. Added `rekey'
3117 field to the SilcChannelEntry in the server. Affected files
3118 silcd/server.c and silcd/idlist.h.
3120 * Added silc_task_unregister_by_context into the file
3121 lib/silcutil/silctask.[ch].
3123 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Added SILC_UMODE_GONE mode to indicate when the client is not
3126 present in the SILC network. Added also support to the local
3127 command AWAY that will set this mode. Added support of showing
3128 "xxx is gone" in WHOIS command. The USERS command shows the
3129 gone status as well.
3131 * Fixed setting server and router operator privileges in the
3132 server's UMODE command. Affected file silcd/command.c.
3134 * Merged the SKE KE1 and KE2 payloads into one payload. The
3135 new KE payload is equivalent to the old KE2 payload.
3137 Cleaned up the SKE Start Payload parsing. It now uses the
3138 simple buffer unformatting to do the parsing. A lot faster
3141 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3142 to the SKE that is used to indicate whether both of the SKE
3143 parties should perform authentication. By default only the
3144 responder performs authentication. By setting this flag also
3145 the initiator must do authentication. By default it is unset
3146 since in normal SKE case, client to server connection, only
3147 the responder should do authentication. When doing SKE between
3148 two clients both should perform authentication. Updated the
3149 code and the protocol specs.
3151 * A little fix to IDENTIFY command in the server. Search the
3152 client first by hash not nickname. Affected file is
3155 * Fixed the silc_client_close_connection to support closing
3156 the client to client connections wihtout deleting too much
3157 data. Affected file lib/silcclient/client.c.
3159 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3160 are received if protocol used to be active but is not anymore
3161 the application would crash due to NULL pointer dereference.
3162 Affected files silcd/server.c and lib/silcclient/client.c.
3164 * Added `hash' field to the SilcClientConnection to include
3165 the hash function negotiated in the SKE protocol.
3167 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3168 to set the channel founder authentication data. A client can
3169 claim the founder rights later by providing the authentication
3170 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3171 This way the channel founder can regain the channel founder
3172 privileges even it is left the channel. This works only on
3173 local server and the client must be connected to the same
3174 server to be able to regain the founder rights. Updated the
3175 protocol specs accordingly.
3177 Added support to the CMODE command in the client to set the
3178 founder auth data. Read the README to see how to set it.
3180 Added support to the CUMODE command to claim the founder
3181 rights. Read the README to see how to do it.
3183 Added support for the founder authentication to the Channel
3184 Entry in the server. Affected file silcd/idlist.h.
3186 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3187 server's CMODE command. Affected file silcd/command.c.
3189 * Added the following new functions into lib/silccore/silcauth.[ch]:
3190 silc_auth_get_method and silc_auth_get_data.
3192 * The server now saves the remote hosts public key to the
3193 SilcIDListData pointer. Affected file silcd/protocol.c.
3195 * The normal server now does not remove the channel entry from
3196 the cache if the founder authentication data is set. It used
3197 to remove it if the founder was the last one on the channel on
3198 the server and left the channel. The auth data is saved and
3199 if the channel is re-joined later the old entry is used with
3200 the old auth data. Affected files silcd/command_reply.c and
3203 * Removed the `pkcs' field from the SilcIDListData structure
3204 in the server; it is not used. Affected file silcd/idlist.h.
3206 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Fixed packet processing on slow links. Partial packets were
3209 never re-processed because the incoming data buffer was cleared
3210 by the application. Application must not directly clear the
3211 sock->inbuf, the packet processing routines handle it. Fixed
3212 this in client library and in server.
3214 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Fixed the WHOIS and IDENTIFY send reply function to really
3217 check whether to send list or just one entry. Affected file
3220 * Cleaned up the LEAVE command's channel key distribution. The
3221 affected file silcd/command.c.
3223 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3224 can enforce the channel mode as well. In that case the ID
3225 includes the ID of the server. The code now enforces the
3226 mode change if the router have different mode than the server.
3228 * The notify client operation with CMODE_CHANGE notify can now
3229 return NULL client_entry pointer if the CMODE was not changed
3230 by client. Application must check for this.
3232 * Added <Server ID> argument to INFO command to support server
3233 info fetching by Server ID.
3235 * Added silc_server_announce_get_channel_users to get assembled
3236 packets of channel users of the specified channel. Affected
3237 file silcd/server.[ch].
3239 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3240 was freed underneath the ID Cache.
3242 * Re-announce clients when the server received CHANNEL_CHANGE
3243 notify from the router. Affected file silcd/packet_send.c.
3245 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3248 crashed since it did not handle the fact that there is no cipher
3249 called "3" and didn't check the error condition. Now fixed.
3251 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3252 flag. It can be used to send message requests.
3254 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Implemented the RESTART command in the client.
3258 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3259 notice type messages. Added notice printing to the user
3262 * The channel keys are not re-generated if the channel's mode
3263 is PRIVKEY, ie private key on the channel exists. Affected
3264 files silcd/server.c and silcd/command.c.
3266 * Fixed a little bug in channel message delivery when channel
3267 private keys are set in the server. Affected file is
3268 silcd/packet_send.c.
3270 * Changed the setting on channel->on_channel = TRUE from the
3271 silc_client_save_channel_key to the JOIN command reply. The
3272 key payload is not received if the private channel key is set.
3273 Affected file lib/silcclient/command_reply.c and the
3274 lib/silcclient/client_channel.c.
3276 * When the CMODE_CHANGE notify is sent and the channel private
3277 key mode is removed the channel key must be re-generated in
3278 other cells as well. Added this support for the router in the
3279 silcd/packet_receive.c.
3281 * Added new local command NOTICE to send notice message on
3282 channel. Affected file silc/local_command.[ch].
3284 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Added new local command ME to the client. It is used to send
3287 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3288 some action. Affected file silc/local_command.[ch].
3290 * Changed channel_message and private_message client operations
3291 to deliver the message flags to the application. Added also
3292 the `flags' arguments to the silc_client_send_channel_message
3293 and silc_client_send_private_message functions. Affected file
3296 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Redefined the Private Message Payload to support private message
3299 keys and to support the new private message flags. Updated
3300 the protocol specs. Flags makes it possible to have for example
3301 CTCP style messages.
3303 * Added new type SilcPrivateMessagePayload and defined an API
3304 for it in the lib/silcclient/silcprivate.[ch].
3306 * Tested private message private keys successfully. Tested the
3307 private message key set, unset and list commands with the new
3310 * Redefined the Channel Message Payload to include the channel
3311 message flags (equal with private message flags) to support
3312 for example CTCP style messages.
3314 * Defined some of the message (for channel and private message)
3315 flags. Updated the protocol specs and added the flags to the
3316 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3318 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added SilcKeyAgreementStatus type to the key agreement routines
3321 to indicate the current status and error if one occured.
3322 The status types are defined in the lib/silcclient/silcapi.h.
3324 * Added new local command KEY that is used to set and unset private
3325 keys for channels, set and unset private keys for private messages
3326 with remote clients and to send key agreement requests and
3327 negotiate the key agreement protocol with remote client. The
3328 key agreement is supported only to negotiate private message keys,
3329 it currently cannot be used to negotiate private keys for channels,
3330 as it is not convenient for that purpose.
3332 * Fixed a minor pending callback setting bug in the function
3333 silc_client_get_client_by_id_resolve, now the function works.
3334 Affected file lib/silcclient/idlist.c.
3336 * Added function silc_net_get_local_port to get local bound
3337 port by socket. Added to lib/silcutil/silcnet.[ch].
3339 * Added `sockets' and `sockets_count' fields to the SilcClient
3340 object. They hold the sockets of the listenning sockets in
3341 the client. Listenning sockets may be for example the key
3342 agreement server. Affected file lib/silcclient/client.[ch].
3343 Added functions the silc_client_add_socket and the
3344 silc_client_del_socket. They are exported to the application
3347 * Added ~./silc/clientkeys to support other client's public keys.
3349 * Renamed verify_server_key client operation to verify_public_key
3350 and added one argument to indicate the type of the connection
3351 (server, client etc.).
3353 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Added silc_server_connection_auth_request to handle the
3356 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3357 silcd/packet_receive.[ch].
3359 * Added silc_server_send_connection_auth_request into the
3360 silcd/packet_send.c to send the connection auth request packet.
3362 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3365 * Fixed the public key authentication in responder side in the
3366 server. The `auth_data' pointer includes the SilcPublicKey
3367 not the path to the public key. Affected file silcd/protocol.c.
3369 * Implemented the public key authentication in the initiator side
3370 in the server. Affected file silcd/protocol.c.
3372 * Removed the [RedirectClient] config section from the server
3373 configuration. Is not needed and I don't want to implement it.
3375 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Cleaned up the CMODE command in the server. It now works
3378 correctly and supports all the modes defined in the protocol.
3379 Affected file is silcd/command.c.
3381 * Added `hmac_name' field to the SilcChannelEntry in the server
3382 to hold the default HMAC of the channel. It can be set when
3383 creating the channel (with JOIN command). Affected files
3386 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3387 type to indicate the change of the current cipher and hmac
3388 on the channel. Client can safely ignore the <cipher> argument
3389 (if it chooses to do so) since the CHANNEL_KEY packet will
3390 force the channel key change anyway. The <hmac> argument is
3391 important since the client is responsible of setting the new
3392 HMAC and the hmac key into use.
3394 * Fixed the CMODE command in the client library as well.
3396 * Tested CMODE command in router environment successfully.
3398 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Show the version of the remote client (or server) when connecting
3401 to the server. It is logged to the log file. Affected file
3402 is silcd/protocol.c.
3404 * Fixed the KILLED notify handling in the client library. The
3405 client must be removed from all channels when receiving the
3408 Also, do not remove the client entry when giving the KILL
3409 command but when the KILLED notify is received.
3411 * Removed silc_idlist_find_client_by_nickname from the server.
3412 Not needed anymore. Affected files silcd/idlist.[ch].
3414 * Implemented the CHANNEL_CHANGE notify type handling to the
3415 server. Affected file silcd/server.c.
3419 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Added silc_server_send_notify_invite to send the INVITE
3422 notify between routers.
3424 * Implemented the INVITE command correctly to the server.
3426 * Implemented the INVITE notify type handling in the server.
3428 * Implemented the INVITE command to the client library and on the
3431 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Added function silc_server_get_client_resolve to find the
3434 client entry by ID from all ID lists and then resolve it
3435 (using WHOIS) if it cannot be found. Affected file is
3438 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Implemented the BAN command to the client library.
3442 * The JOIN command in the server now checks the invite list
3445 * Changed the silc_command_reply_payload_encode_va and the
3446 silc_command_payload_encode_va to support that if argument is
3447 NULL it ignores and checks the next argument. Affected file
3448 lib/silccore/silccommand.c.
3450 * Added silc_server_send_notify_ban to send the BAN notify
3451 type between routers.
3453 * Chaned the silc_notify_payload_encode to support that if
3454 argument is NULL it ignores and checks the next argument.
3455 Affected file lib/silccore/silcnotify.c.
3457 * Tested ban lists in router environment successfully.
3459 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Implemented BAN command to the server, in silcd/command.[ch].
3463 * Removed the BAN and INVITE_LIST modes from the CMODE command
3466 * Added function silc_string_match to regex match two strings.
3467 Affected files lib/silcutil/silcutil.[ch].
3469 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Redefined parts of the SilcChannelEntry in the server to support
3472 the new ban and invite lists.
3474 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Redefined the INVITE command. The same command can be used to
3477 invite individuals to the channel but also to manage the invite
3478 list of the channel (to add to and remove from the invite list).
3479 Updated the protocol specs.
3481 * Added new command SILC_COMMAND_BAN that can be used to manage
3482 the ban list of the channel. Updated the protocol specs.
3484 * Removed the channel modes: the SILC_CMODE_BAN and the
3485 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3486 in the CMODE command. The equivalent features are now available
3487 using INVITE and BAN commands. Updated the protocol specs.
3489 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3490 in the network about change in the current ban list. The notify
3491 type is not used by the client.
3493 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3494 support the invite lists.
3496 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Added new function silc_string_regexify that converts string
3499 including wildcard characters into regex string that can
3500 be used by the GNU regex library. Added into the file
3501 lib/silcutil/silcutil.[ch].
3503 Added silc_string_regex_combine to combine to regex strings
3504 into one so that they can be used as one regex string by
3505 the GNU regex library. Added into the file
3506 lib/silcutil/silcutil.[ch].
3508 Added silc_string_regex_match to match two strings. It returns
3509 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3511 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Imported GNU regex to the soruce tree into lib/contrib.
3514 Fixed some compiler warning from the regex.c.
3516 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Fixed MOTD command in the server to work in router environment.
3520 * Fixed the MOTD command in the client library to support
3521 the server argument in the command.
3523 * Added `nickname_len' argument to the silc_idlist_add_client
3524 in the server, as the `nickname' argument may be binary data
3527 * Added silc_idlist_get_channels to return all channels from
3530 * Implemented LIST command to the server. Affected file is
3533 * Implemented the LIST command to the client library and on the
3536 * Added [<user count>] argument to the LIST command reply.
3537 With private channels the user count is not shown.
3539 * Updated TODO and README.
3541 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * The client entry's data.registered must be TRUE even with
3544 global client entry on global client list. The data.registered
3545 is used to check whether the client is anymore in the network,
3546 for example with WHOWAS command so it must be valid.
3548 * Fixed the WHOWAS command in the server. It now actually works
3549 in router environment. Added function into silcd/command_reply.c
3550 silc_server_command_reply_whowas_save.
3552 * Added silc_idlist_purge function to the silcd/idlist.c
3553 to periodically purge the ID Cache.
3555 * Fixed INFO command in the server. It works now in router
3556 environment. Added <server name> argument to the INFO command
3557 reply. Updated the protocol specs.
3559 * Fixed minor bug in silc_idcache_purge to not purge if the
3560 expire value is zero.
3562 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3563 they were buggy because of the WHOWAS information.
3565 * Fixed local command MSG to handle the async resolving of
3566 the remote client properly. It used to fail the first MSG.
3567 Affected file silc/local_command.c.
3569 * Added `data_len' field to SilcIDCache context.
3571 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Update TODO. Todo in commands in the server.
3575 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3578 used by routers as broadcast packet to inform other routers
3579 about the changed user mode.
3581 Implemented the notify handling in the server. Affected file is
3582 silcd/packet_receive.c. Added the function
3583 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3585 * Added new generic Channel Payload and deprecated the New Channel
3586 Payload. The New Channel Payload is now the generic Channel
3589 * Added new argument `mode' to the silc_server_send_new_channel
3590 as it is required in the Channel Payload now.
3592 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3593 and created a new and real SilChannelPayload to represent the
3594 new generic Channel Payload. Implemented the encode/decode
3595 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3597 * Added silc_server_get_client_channel_list to return the list
3598 of channels the client has joined for WHOIS command reply.
3599 Affected file silcd/server.[ch].
3601 * Implemented the channel list sending in the WHOIS command reply
3602 in server and in the client.
3604 Implemented the channel list displaying on the user interface
3605 as well. Affected file silc/client_ops.c.
3607 * Added silc_channel_payload_parse_list to parse list of Channel
3608 Payloads. It returns SilcDList list of SilcChannelPayloads.
3609 Client for example can use this function to parse the list of
3610 channels it receives in the WHOIS command reply. The caller
3611 must free the list by calling silc_channel_payload_list_free.
3612 Affected files lib/silccore/silcchannel.[ch].
3614 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Added one new argument <user mode> to the WHOIS command reply
3617 to return the mode of the user in SILC. Updated the protocol
3620 Implemented it to the server and client.
3622 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Fixed the mode printing on the user interface on joining.
3625 Affected file silc/client_ops.c.
3627 * Implemented the UMODE command and user modes in general to the
3628 client library and to the user interface.
3630 * Implemented the UMODE command to the server.
3632 * The server now sends UNKNOWN_COMMAND error status if client sends
3633 unknown command. Affected file silcd/command.c.
3635 * All server commands now handle the command identifier the right
3636 way when sending the command reply to the client. The client can
3637 use to identify the command replies with the identifier.
3639 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Added silc_server_get_client_route to resolve the route to
3642 the client indicated by the client ID. Affected file is
3645 * Added silc_server_relay_packet as general function to relay
3646 packet to arbitrary destination. This deprecates functions
3647 like _send_private_message_key, _relay_notify etc. Affected
3648 file is silcd/packet_send.[ch].
3650 Removed silc_server_send_key_agreement,
3651 silc_server_send_private_message_key and
3652 silc_server_packet_relay_notify functions from the file
3653 silcd/packet_send.[ch].
3657 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3658 server. Affected file silcd/packet_receive.[ch].
3660 * Implemented the KILL command to the client. Implemented the
3661 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3662 Affected files lib/silcclient/command[_reply].c and
3663 lib/silcclient/client_notify.c. Implemented the KILL notify
3664 printing in the user inteface.
3666 * Fixed a lot silc_parse_nick memory leaks from the client
3667 library in the file lib/silcclient/command.c.
3669 * Changed the silc_server_send_notify_on_channels's `sender'
3670 argument from SilcSocketConnection to SilcClientEntry to
3671 check the sender as entry and not as connection object and not
3672 to send to the client provided as argument. The affected file
3673 is silcd/packet_send.[ch].
3675 * The notify packets that are destined directly to the client used
3676 to not to be processed by the server. Now changed that and the
3677 server processes all notify packets. After relaying the packet
3678 to the client the notify packet is processed in the server.
3680 * The silc_server_free_client_data now checks whether there is
3681 pending outgoing traffic for the client and purges the data to
3682 the network before removing the client entry.
3684 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3687 an client is killed from the SILC Network. Updated the protocol
3690 Added new function silc_server_send_notify_killed to the
3691 silcd/packet_send.[ch].
3693 * Added function silc_server_packet_relay_notify to relay notify
3694 packets that are destined directly to a client. In this case
3695 the server does not process the notify packets but merely relays
3696 it to the client. Affected file silcd/packet_send.[ch].
3698 Added also silc_server_packet_process_relay_notify to check
3699 whereto relay the notify. Affected file is
3700 silcd/packet_receive.[ch].
3702 * Implemented the KILL command to the server.
3706 * Added the backup schema desgined last fall to the protocol
3707 specs for everyone to see. The specification is in the
3708 *-spec-xx.txt draft and the packet type definitions for the
3709 backup routers is in *-pp-xx.txt draft. Thusly, added also
3710 new packet type SILC_PACKET_CELL_ROUTERS.
3712 * A big security problem in the implementation discovered. The
3713 signoff of an client did not cause new channel key generation
3714 which it of course should've done. The channel keys must be
3715 always re-generated when client leaves (or signoffs) the channel.
3716 The silc_server_remove_from_channels funtion now handles
3717 the channel key re-generation.
3719 * Added `sender' argument to the silc_server_send_notify_on_channels
3720 to not to send the client provided as argument. Affected file
3721 silcd/packet_send.[ch].
3723 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Implemented OPER and SILCOPER commands into the server and
3728 * Added silc_auth_verify and silc_auth_verify_data to verify
3729 the authentication directly from the authentication payload.
3730 It supports verifying both passphrase and public key based
3731 authentication. Affected file lib/silccore/silcauth.[ch].
3733 * Added `hash' field to the SilcIDListData structure. It is the
3734 hash negotiated in the SKE protocol. Affected file is
3737 * Slight redesigning of the SilcAuthPayload handling routines.
3738 Do not send SilcPKCS but SilcPublicKey as argument.
3740 * Implemented the public key authentication support to the
3741 serverconfig. The public key is loaded from the provided path
3742 and saved as authentication data to void * pointer. Thus,
3743 changed the unsigned char *auth_data to void *auth_data;
3745 * Fixed SHUTDOWN command to send the reply before the server
3746 is shutdown. :) Affected file silcd/command.c.
3748 * Fixed fatal bug in CONNECT command. The hostname was invalid
3749 memory and server crashed. Affected file silcd/command.c.
3751 * Fixed fatal bug in CLOSE command. The server_entry became
3752 invalid but was referenced later in the command. Affected file
3755 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Fixed fatal bug in failure packet handling. Server ignored
3758 the failure and thus crashed when it came.
3762 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3765 that the command may be executed only once in (about) 2 seconds.
3766 The old SILC_CF_LAG flag is same but allows command bursts up
3767 to five before limiting.
3769 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3770 server code. Various commands now includes the CF_LAG_STRICT
3771 flag to disallow any kind of miss-use of the command.
3773 * Fixed the silc_buffer_unformat to not to allocate any data
3774 if the length of the data is zero. It used to allocate the
3775 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3777 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Changed the format of AdminConnection configuration section
3780 in the server. Added username of the admin to the format.
3781 Affected files silcd/serverconfig.[ch].
3783 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3784 to return admin configuration data by host, username and/or
3787 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Implemented WHOWAS command to the server. Added the functions:
3791 silc_server_command_whowas_parse,
3792 silc_server_command_whowas_send_reply,
3793 silc_server_command_whowas_from_client and
3794 silc_server_command_whowas_from_server
3796 * Added <Client ID> argument to the WHOWAS command reply. Updated
3797 the protocol specs accordingly.
3799 * Implemented WHOWAS command and command_reply to the client
3802 Implemented the WHOWAS printing on the user interface.
3804 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Added new argument to the WHOWAS command reply, the real name.
3807 It is an optional argument. Updated the protocol specs.
3809 * Added SilcIDCacheDestructor callback that is registered when
3810 the SilcIDCache is allocated. The callback is called when
3811 an cache entry in the ID Cache expires, or is purged from the
3812 cache. Added into lib/silccore/idcache.[ch].
3814 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3815 to destruct the client entries when the cache entry expires.
3816 Other ID Cache's in server and in the client library ignores
3819 * If the ID Cache entry's `expire' field is zero then the entry
3820 never expires. Added boolean `expire' argument to the
3821 silc_idcache_add function in the lib/silccore/idcache.[ch].
3822 If it is TRUE the default expiry value is used.
3824 * Added silc_server_free_client_data_timeout that is registered
3825 when client disconnects. By default for 5 minutes we preserve
3826 the client entry for history - for WHOWAS command.
3828 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Added support to the server to enforce that commands are not
3831 executed more than once in 2 seconds. If server receives
3832 commands from client more frequently, timeout is registered
3833 to process the commands. Affected file silcd/command.c.
3834 Added new function silc_server_command_process_timeout.
3836 * Changed NICK_NOTIFY handling in client library to check that
3837 if the client's nickname was changed, so there is no need to
3838 resolve anything from the server.
3840 * Removed error printing from the WHOIS and IDENTIFY commands.
3841 If error occurs then it is ignored silently in the client library.
3842 The application, however, may map the received error to
3843 human readable error string. The application currently maps
3844 the NO_SUCH_NICKNAME error to string.
3846 * Made the command status message public to the application. Moved
3847 them from lib/silcclient/command_reply.c to
3848 lib/silcclient/command_reply.h. The application can map the
3849 received command status to the string with the
3850 silc_client_command_status_message function.
3852 * Added check to the server to check that client's ID is same
3853 as the Source ID in the packet the client sent. They must
3856 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Added dist-bzip hook to the Makefile.am to make bzip2
3859 compressed distributions.
3861 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Server now enforces the maximum length for the nickname and
3864 the channel as protocol specification dictates. 128 bytes for
3865 nickname and 256 bytes for channel name.
3867 * Moved the WHOIS printing to the application. The client libary
3868 does not print out the WHOIS information anymore, the application
3869 must do it. Renamed silc_client_command_reply_whois_print to
3870 the silc_client_command_reply_whois_save.
3872 The client's idle time is also sent to the application now, and
3873 the idle is shown on screen.
3875 * Added silc_client_command_reply_identify_save to save the
3876 received IDENTIFY entries.
3878 * Do not check for channel private keys in message sending and
3879 reception if the channel does not have the PRIVKEY mode set.
3880 Affected file lib/silclient/client_channel.c.
3882 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3885 just surfaced after chaning the JOIN procedure.
3887 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Added silc_client_get_clients_by_list to get client entries
3890 from Client ID list, that is returned for example by JOIN
3891 and USERS command replies. The application should use this
3892 function for example when JOIN command reply is received to
3893 resolve the clients already on the channel (library does not
3894 do that anymore as USERS command reply is not used in the JOIN
3895 procedure anymore). Affected files lib/silcclient/silcapi.h and
3896 lib/silcclient/idlist.c.
3898 * JOIN command reply and USERS command reply returns now SilcBuffer
3899 pointers instead of unsigned char pointers when returning
3900 the client list and mode list.
3902 * Added <Client ID> argument to the JOIN command reply, mainly
3903 for the server to identify for which client the command was
3904 originally sent. Updated protocol specs accordingly.
3906 * Added SilcDlist private_key pointer to the SilcChannelEntry
3907 in the client to support the channel private keys. Affected
3908 file is lib/silcclient/idlist.h.
3910 * Added SilcChannelPrivateKey argument to the function
3911 silc_client_send_channel_message so that application can choose
3912 to use specific private ke if it wants to. If it is not provided,
3913 the normal channel key is used, unless private keys are set.
3914 In this case the first (key that was added first) is used
3915 as the encryption key.
3917 * Implemented the support for channel private key handling.
3918 Implemented the following functions:
3920 silc_client_add_channel_private_key,
3921 silc_client_del_channel_private_keys,
3922 silc_client_del_channel_private_key,
3923 silc_client_list_channel_private_keys and
3924 silc_client_free_channel_private_keys
3926 Affected file lib/silcclient/client_channel.c.
3928 * Added the support for the private keys in the channel message
3929 sending and encryption and in the message reception and
3930 decryption. Affected funtions are
3931 silc_client_send_channel_message and silc_client_channel_message.
3933 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Added SKE's key verify callback to the client library's
3936 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3938 * Removed the statement that server (or router) must send USERS
3939 command reply when joining to the channel so that the client
3940 knows who are on the channel. Instead, the client list and
3941 client's mode list is now sent in the JOIN command reply to the
3942 client who joined channel. This is better solution.
3944 * Added function silc_server_get_users_on_channel and function
3945 silc_server_save_users_on_channel to the silcd/server.[ch].
3947 * Removed function silc_server_command_send_users from the
3950 * Do not show topic on the client library anymore. The topic is
3951 sent in the command reply notify to the application and the
3952 application must show the topic now.
3954 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added client searching by nickname hash into the IDENTIFY and
3957 WHOIS commands in the server as they were clearly missing from
3958 them. Affected file is silcd/command.c.
3960 * Fixed a bug in private message receiving in the client library.
3961 The remote ID was freed and it wasn't supposed, now it is
3964 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Minor fix to the channel payload; allocate the data area, as it
3967 needs to be of specific length.
3969 * If the key agreement port is zero then the operating
3970 system will define the bound port. Affected files are
3971 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3973 * Added new function silc_channel_payload_decrypt into the file
3974 lib/silccore/silcchannel.[ch].
3976 * Moved the channel message etc, check from silc_packet_decrypt
3977 to applications. The library calls now a generic
3978 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3979 when the packet is either normal or special. This was done to
3980 allow more wide range of checking that was not allowed when
3981 the code was in library. Now applications can do virtually any
3982 checks to the packet and return to the library the decision how
3983 the packet should be processed. Affected files are
3984 lib/silccore/silcpacket.[ch].
3986 Added silc_server_packet_decrypt_check to the server and
3987 silc_client_packet_decrypt_check to the client library.
3989 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3990 to send with specified source and destination information.
3992 * Channel message delivery between routers was broken after the
3993 channel key distribution was fixed earlier. The channel key
3994 was used be to distributed to other routers as well which is not
3995 allowed by the protocol. Now this is fixed and channel keys
3996 really are cell specific and the channel message delivery between
3997 routers comply with the protocol specification.
3999 * Fixed various commands in server to check also the global list
4000 for the channel entry and not just the local list. The affected
4001 file silcd/command.c.
4003 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Added assert()s to buffer formatting and unformatting routines
4006 to assert (if --enable-debug) when error occurs. Affected
4007 file: lib/silcutil/silcbuffmt.c.
4009 * Changed to auto-reconnect to check whether the remote host is
4010 router and register the re-connect timeout if it is. It used
4011 to check that whether we are normal server, but router must do
4012 auto-reconnect with another router as well. Affected file
4015 * Removed the [<key len>] option from CMODE command as the cipher
4016 name decides the key length, nowadays. See the defined ciphers
4017 from the protocol specification.
4019 * Added [<hmac>] option to the CMODE command to define the HMAC
4020 for the channel. Added SILC_CMODE_HMAC channel mode.
4022 * Added [<hmac>] option for the JOIN command so that user can
4023 select which HMAC is used to compute the MACs of the channel
4026 * Added Hmac field to the Channel Message Payload. The integrity
4027 of plaintext channel messages are now protected by computing
4028 MAC of the message and attaching the MAC to the payload. The
4029 MAC is encrypted. Now, it is clear that this causes some
4030 overhead to the size of the packet but rationale for this is that
4031 now the receiver can verify whether the channel message decrypted
4032 correctly and also when private keys are set for the channel the
4033 receiver can decrypt the packet with several keys and check from
4034 the MAC which key decrypted the message correctly.
4036 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4037 lib/silccrypt/silccipher.[ch].
4039 * Added silc_hash_len to return the digest length into the
4040 lib/silcrypt/silchash.[ch].
4042 * Rewrote parts of Silc Channel Payload interface in the
4043 lib/silccore/silcchannel.[ch]. The encode function now also
4044 encrypts the packet and parse function decrypts it.
4046 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Fixed a minor formatting bug in the SKE's key material processing.
4049 It actually might have processed the keys wrong way resulting
4052 * Redefined the mandatory HMAC algorithms and added new algorithms.
4053 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4054 and hmac-md5 truncated to 96 bits. The mandatory is now
4055 hmac-sha1-96. Rest are optional (including the one that used
4056 to be mandatory). Rationale for this is that the truncated HMAC
4057 length is sufficient from security point of view and can actually
4058 make the attack against the HMAC harder. Also, the truncated
4059 HMAC causes less overhead to the packets. See the RFC2104 for
4062 * Added new [hmac] configuration section. The SKE used to use
4063 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4064 is of course wrong. The official names that must be proposed in
4065 the SKE are the ones defined in the protocol specification
4066 (hmac-sha1-96 for example). The user can configure any hmac
4067 using any hash function configured in the [hash] section. At
4068 least, the mandatory must be configured.
4070 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4072 * Added HMAC list to the SKE proposal list. It has now both
4073 hash algorithm list and HMAC list. This makes the protocol
4074 incompatible with previous versions. The SKE now seems to work
4075 the way it is supposed to work, for the first time actually.
4077 * Defined plain Hash algorithms to the protocol specification.
4080 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Implemented support for key agreement packets into the server.
4083 Added functions silc_server_key_agreement and
4084 silc_server_send_key_agreement. Other than these functions,
4085 server has nothing to do with this packet.
4087 * Added support for private message key packets into the server.
4088 Added functions silc_server_private_message_key and
4089 silc_server_send_private_message_key.
4093 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4094 called in the protocol's final callback instead in the END
4095 protocol state. This makes a little more sense and in the same
4096 time in client we can use the same protocol routines for normal
4097 key exchange and to key agreement packet handling as well.
4099 * Added to both client's and server's KE protocol context the
4100 SilcSKEKeyMaterial pointer to save the key material. We will
4101 bring the key material to the protocol's final callback by doing
4102 this. The final callback must free the key material.
4104 * Added SKE's packet_send callback into client's KE protocol
4105 context so that the caller can choose what packet sending function
4106 is used. This way we can use different packet sending when
4107 doing normal SKE when doing key agreement packet handling (in
4108 the key agreement packet handling we do not want to encrypt
4111 * Implemented the responder side of the key agreement routines
4112 in the client. The client can now bind to specified port and
4113 accept incoming key negotiation. The key material is passed
4114 to the application after the protocol is over.
4116 * Implemented the processing of incoming Key Agreement packet
4117 in the client. Added function silc_client_key_agreement to
4120 * Implemented the intiator side of the key agreement routines
4121 in the client. The client can now initiate key agreement with
4122 another remote client. The key material is passed to the
4123 application after the protocol is over.
4125 * Created client_keyagr.c to include all the key agreement
4128 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4129 SILC_TASK_CALLBACK except that it is not static.
4131 * Created client_notify.c and moved the Notify packet handling
4132 from the client.[ch] into that file.
4134 * Created client_prvmsg.c and moved all private message and
4135 private message key routines from the client.[ch] into that file.
4137 * Create client_channel.c and moved all channel message and
4138 channel private key routines from the client.[ch] into that file.
4140 * Changed silc_client_get_client_by_id_resolve to resolve with
4141 WHOIS command instead of IDENTIFY command, in the file
4142 lib/silclient/idlist.c.
4144 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Implemented the SKE's responder side to the Client library.
4148 * When FAILURE is received to the protocol do not trust it
4149 blindly. Register a timeout to wait whether the remote closes
4150 the connection as it should do it, only after that process the
4151 actual failure. This was changed to both client and server.
4153 * Added client_internal.h to include some of the structures
4154 there instead of client.h in lib/silcclient/.
4156 * Added function silc_task_unregister_by_callback to unregister
4157 timeouts by the callback function.
4159 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Some "Incomplete WHOIS info" errors has been appearing on the
4162 log files. Took away the entry->userinfo check from WHOIS
4163 reply sending. The entry->userinfo is now " " if client did not
4164 provide one. I thought this was fixed earlier but something
4165 is wrong still. Let's see if the error still appears.
4167 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Fixed a minor bug in the login when the channel key is
4170 re-generated in the server. It used to generate the key in
4171 wrong order and thus caused problems in the channel traffic.
4173 * Fixed a minor bug in channel key distsribution after
4174 KICK command. The key was not sent to the router even though
4177 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Added silc_ske_process_key_material_data as generic routine
4180 to process any key material as the SILC protocol dictates. The
4181 function is used by the actual SKE library but can be used by
4182 applications as well. This relates to the private message keys
4183 and the channel private keys since they must be processed the
4184 same way the normal SILC session keys. The protocol dictates
4185 this. Affected files: lib/silcske/silcske.[ch].
4187 Added also silc_ske_free_key_material to free the
4188 SilcSKEKeyMaterial structure.
4190 * Defined silc_cipher_set_key function to set the key for
4191 cipher without using the object's method function. The affected
4192 files: lib/silccrypt/silccipher.[ch].
4194 * Implemented silc silc_client_add_private_message_key,
4195 silc_client_add_private_message_key_ske,
4196 silc_client_del_private_message_key,
4197 silc_client_list_private_message_keys and
4198 silc_client_free_private_message_keys functions in the
4201 Added functions silc_client_send_private_message_key to send
4202 the Private Message Key payload and silc_client_private_message_key
4203 to handle incoming Private Message Key payload.
4205 * Added Cipher field to the Private Message Key payload to set
4206 the cipher to be used. If ignored, the default cipher defined
4207 in the SILC protocol (aes-256-cbc) is used.
4209 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Removed lib/silcclient/ops.h file.
4213 Redefined parts of the SILC Client Library API. Created new
4214 file silcapi.h that deprecates the ops.h file and defines the
4215 published Client Library API. Defined also private message key
4216 API and channel private key API into the file.
4218 This is the file that the application must include from the
4219 SILC Client Library. Other files need not be included by
4220 the application anymore.
4222 * Added new key_agreement client operation callback and also
4223 defined the Key Agreement library API for the application.
4225 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4228 is used by clients to request key negotiation between another
4229 client in the SILC network. If the negotiation is started it
4230 is performed using the SKE protocol. The result of the
4231 negotiation, the secret key material, can be used for example
4232 as private message key.
4234 Implemented the Key Agreement payload into the files
4235 lib/silccore/silauth.[ch].
4237 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Redefined ciphers for the SILC protocol. Added some new ciphers
4240 and defined the key lengths for the algorithms. Changed the
4241 code accordingly. The default key length is now 256 bits.
4243 * Fixed SKE key distribution function silc_ske_process_key_material
4244 when the key length is more than 128 bits. The default key
4245 length in SILC is now 256 bits.
4247 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4248 to indicate unsupported algorithm.
4250 * Renamed rijndael.c to aes.c and all functions as well.
4252 * Fixed a long standing channel key setting bug in client library.
4253 Weird that it has never surfaced before.
4255 * Fixed bug in channel deletion. If the entire channel is removed
4256 then it must also delete the references of the channel entry
4257 from the client's channel list as the client's channel entry and
4258 the channel's client entry share same memory.
4260 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Implemented CONNECT and SHUTDOWN commands in the client.
4264 * Implemented CLOSE command to the client.
4266 * Added the function silc_idlist_find_server_by_name into the
4267 files silcd/idlist.[ch].
4269 Added the function silc_idlist_find_server_by_conn into the
4270 files silcd/idlist.[ch].
4272 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * DIE command was renamed to SHUTDOWN. Updated the both code
4277 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4278 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4280 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4283 * Added function silc_server_create_connection function to create
4284 connection to remote router. My server implementation actually
4285 does not allow router to connect to normal server (it expects
4286 that normal server always initiates the connection to the router)
4287 so the CONNECT command is only good for connecting to another
4290 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4293 or some other client was kicked from the channel.
4295 Implemented the handling of the notify type to both client
4298 Implemented silc_server_send_notify_kicked to send the KICKED
4299 notify. It is used to send it to the server's primary router.
4301 * Implemented the KICK command into server and client.
4303 * Added `query' argument to the silc_idlist_get_client function
4304 to indicate whether to query the client from server or not if
4307 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4308 to indicate that the client is not channel founder.
4312 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Removed the rng context from SilcPacketContext structure and
4315 changed that the packet routine uses the Global RNG API.
4317 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Added support for quit message that client can "leave" on the
4320 channel when it quits the SILC. It is ditributed inside the
4321 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4323 Added silc_server_free_client_data that will take the
4324 signoff message as argument.
4326 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4328 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Updated parts of the protocol specification to keep it up
4333 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4336 payloads in one packet.
4338 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4339 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4340 use now the new List flag.
4342 * Also deprecated the following packet types: REPLACE_ID,
4343 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4345 * Added list support for Notify packet in server.
4347 * Added silc_server_send_notify_channel_change to send the
4348 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4349 the silc_server_send_replace_id.
4351 * Added silc_server_send_notify_nick_change to send the
4352 NICK_CHANGE notify type. Deprecates the function
4353 silc_server_send_replace_id.
4355 * Added silc_server_send_notify_join to send the JOIN notify type.
4356 Deprecates the function silc_server_send_new_channel_user.
4358 * Added silc_server_send_notify_leave to send LEAVE notify type.
4359 Deprecates the function silc_server_send_remove_channel_user.
4361 * Added silc_server_send_notify_cmode and
4362 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4363 types. Deprecates the silc_server_send_set_mode function.
4365 * Added SERVER_SIGNOFF notify type to indicate that server has
4366 quit. This means that all clients on the channel from that
4367 server will drop. This can be also used when netsplit happens.
4369 Deprecated REMOVE_ID packet type since it is not needed anymore
4372 Added silc_server_send_notify_server_signoff to send the
4373 SERVER_SIGNOFF notify type. Deprecates the function
4374 silc_server_send_remove_id.
4376 Added also silc_server_send_notify_signoff to send the
4377 SIGNOFF notify type.
4379 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4380 SILC protocol from this day on. Changed the protocol
4381 specification as well.
4383 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4384 notify type. It is used between routers to notify about
4385 topic changes on a channel.
4387 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4390 * Partly updated the protocol specification to comply with the
4391 changes now made. It is still though a bit outdated.
4393 * The JOIN notify type now takes one extra argument <Channel ID>.
4394 The packet used to be destined to the channel but now the
4395 JOIN type may be sent as list thus it is impossible to
4396 destine it to any specific channel. By adding this argument
4397 it is again possible.
4399 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Added CREDITS file. The CHANGES and CREDITS file will appear
4402 in the distribution as well.
4404 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4407 types in the server's silcd/packet_receive.c.
4409 * Implemented CMODE and CUMODE to work in router environment.
4411 * Fixed minor encoding and decoding buglet from the
4412 lib/silccore/silcmode.c.
4414 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4417 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4419 * Changed all SilcConfigServer* and silc_config_server* to
4420 SilcServerConfig* and silc_server_config*, respectively.
4423 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Associated the ID (client or server ID) to the Authentication
4426 Payload to avoid any possibility of forging. Updated the
4427 protocol specification and the code accordingly.
4429 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * The RSA key length is now save to the RsaKey context in the
4432 key generation process in lib/silccrypt/rsa.c. The key length
4433 is now used to figure out the maximum size of the block allowed
4434 to be encrypted/signed.
4436 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4437 is equivalent to the silc_mp_mp2bin but does not allocate any
4440 * Changed silc_mp_mp2bin API to take length argument. If it is
4441 non-zero then the buffer is allocated that large. If zero, then
4442 the size is approximated using silc_mp_sizeinbase, which however
4445 * Created Global RNG API which is global RNG that application can
4446 initialize. After initializing, any routine anywhere in the
4447 code (including library) can use RNG without allocating a new
4448 RNG object. This was done to allow this sort of use of the
4449 RNG in code that has no chance to allocate RNG object. All
4450 applications currently allocate this and many routines in the
4451 library use this. Affected file lib/silccrypt/silcrng.[ch].
4453 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4454 it to use the Global RNG API.
4456 * Defined Authentication Payload into protocol specification that
4457 is used during SILC session to authenticate entities. It is
4458 used for example by client to authenticate itself to the server
4459 to obtain server operator privileges.
4461 Implemented this payload into the lib/silccore/silcauth.[ch].
4462 Implemented also routines for public key based authentication
4463 as the new protocol specification dictates.
4465 Moved definitions of different authentication methods from
4466 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4468 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4469 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4470 silc_pkcs_verify_with_hash functions into the file
4471 lib/silccrypt/silcpkcs.[ch].
4473 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * The client entry's userinfo pointer must be always valid.
4476 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4477 will fail since it requires the userinfo. Now, the userinfo
4478 is allocated as "" if actual userinfo does not exist. Actually,
4479 it must exist and it is totally Ok to drop client connections
4480 that does not announce the userinfo. However, we will make
4481 this workaround for now.
4483 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4484 to return the remote port by socket.
4486 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4489 SILC_SERVER_PENDING_EXEC and added an new macro
4490 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4491 data or when error occurs while processing the pending command.
4493 Added new argument `destructor' into silc_server_command_pending
4494 and to the SilcServerCommandPending object. This destructor is
4495 now called after calling the pending callback or if error occurs
4496 immediately. If error occurs the actual pending callback won't
4497 be called at all - only the destructor. The destructor may be
4498 NULL if destructor is not needed.
4500 All this applies for client library code as well. Similar
4501 changes were made there as well for the pending commands.
4503 In the client, the application must now allocate the
4504 SilcClientCommandContext with the silc_client_command_alloc
4507 * Added reference counter to the SilcServerCommandContext. Added
4508 function silc_server_command_alloc and silc_server_command_dup
4511 Same type of functions added to the client library for the same
4514 * Removed the cmd_ident from IDListData away since it is now
4515 global for all connections. It is the command identifier used
4516 in command sending and with pending commands. The affected file
4519 * Added reference counter to the SilcSocketConnection objecet to
4520 indicate the usage count of the object. The object won't be
4521 freed untill the reference counter hits zero. Currently only
4522 server uses this, and client ignores it. The client must be
4523 set to use this too later. The affected files are
4524 lib/silccore/silcsockconn.[ch]. Added also the function
4525 silc_socket_dup to increase the reference counter.
4527 This was mainly added because it is possible that the socket
4528 is removed underneath of pending command or other async
4529 operation. Now it won't be free'd and proper DISCONNECTING
4530 flags, etc. can be set to avoid sending data to connection that
4531 is not valid anymore.
4533 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4534 the connection. After that it sets SILC_SET_DISCONNECTED.
4535 It is, however, possible that the socket data is not still freed.
4536 The silc_server_packet_process now checks that data is not
4537 read or written to connection that is DISCONNECTED. The socket
4538 get's freed when the reference counter hits zero.
4540 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Changed the client operation API: channel_message operation's
4543 `sender' is now the client entry of the sender, not the nickname
4544 and the `channel' is the channel entry, not the channel name.
4546 In the private_message operation the `sender' is now also the
4547 client entry of the sender not the nickname.
4549 Affected file is lib/silcclient/ops.h and all applications
4550 using the client operations.
4552 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Moved the calling of ops->connect() from connect_to_server_final
4555 into receive_new_id functin since that is the point when the
4556 client is actually allowed to send traffic to network. The
4557 affected file is lib/silcclient/client.c.
4559 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4562 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4563 (if needs broadcasting) instead of broadcasting the packets one
4564 by one which would make a burst in the network traffic.
4566 * Added `broadcast' argument to the functions in silcd/server.[ch]
4567 silc_server_create_new_channel[_with_id] to indicate whether
4568 to send New Channel packet to primary router.
4570 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Added new function into the silcd/server.[ch] files:
4573 silc_server_create_new_channel_with_id to create new channel with
4574 already existing Channel ID.
4576 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4577 lib/silccore/silcpacket.h. This packet is used t send list of
4578 Set Mode payloads inside one packet. Server uses this to set
4579 the modes for the channels and clients on those channels, that it
4580 announced to the router when it connected to it. The protocol
4581 specification has been updated accordingly.
4583 * The silc_server_new_channel did not handle the packet coming
4584 from normal server as it normally does not send that. However,
4585 when it announces its channels it does send it. Implemented
4586 the support for that.
4588 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4589 into the file lib/silccore/id.h.
4591 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Fixed memory leaks in the functions silc_idlist_del_client,
4594 silc_idlist_del_channel and silc_idlist_del_server in the file
4595 silcd/idlist.c. All of those leaked like a sieve.
4597 * Fixed some small memory leaks in the client's function
4598 silc_client_notify_by_server.
4600 * Added functions into silcd/server.c: silc_server_announce_clients,
4601 silc_server_announce_channels and silc_server_announce_server.
4602 These functions are used by normal and router server to announce
4603 to its primary router about clients, channels and servers (when
4604 router) that we own. This is done after we've connected to the
4607 These functions effectively implements the following packet types:
4608 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4609 and SILC_PACKET_NEW_ID_LIST.
4611 * Added new functions into the silcd/packet_receive.[ch]:
4612 silc_server_new_id_list, silc_server_new_channel_list and
4613 silc_server_new_channel_user_list to handle the incoming
4614 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4616 * Added support of changing Channel ID in the function
4617 silc_server_replace_id. If the server that announces a channel
4618 to the router already exists in the router (with same name but
4619 with different Channel ID), router is responsible to send
4620 Replace ID packet to the server and force the server to change
4621 the Channel ID to the one router has.
4623 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4624 client that the Channel ID has been changed by the router. The
4625 normal server sends this to the client. Client must start using
4626 the new Channel ID as the channel's ID.
4628 Implemented handling of this new type into lib/silcclient/client.c
4629 into the function silc_client_notify_by_server.
4631 * Added new function silc_idlist_replace_channel_id into the files
4632 silcd/idlist.[ch] to replace the Channel ID.
4634 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Call silc_server_command_identify_check always when processing
4637 the IDENTIFY command in silcd/command.c
4639 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4642 send keepalive packets. The packet can be sent by clients,
4643 servers and routers.
4645 Added function silc_socket_set_heartbeat into the file
4646 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4647 If not set, the heartbeat is not performed. The actual
4648 heartbeat is implemented in the low level socket connection
4649 library. However, application is responsible of actually
4652 Added silc_server_send_heartbeat to send the actual heartbeat
4653 packet into silcd/packet_send.[ch]. Server now performs
4654 keepalive with all connections.
4656 * Added silc_task_get_first function into lib/silcutil/silctask.c
4657 to return the timeout task with shortest timeout. There was a bug
4658 in task unregistration that caused problems. TODO has been
4659 updated to include that task system must be rewritten.
4661 * The client library will now resolve the client information when
4662 receiving JOIN notify from server for client that we know but
4663 have incomplete information.
4665 * Rewrote parts of silc_server_remove_from_channels and
4666 silc_server_remove_from_one_channel as they did not remove the
4667 channel in some circumstances even though they should've.
4669 * Encryption problem encountered in server:
4671 The LEAVE command used to send the Channel Key packet to the
4672 router immediately after generating it. However, the code
4673 had earlier sent Remove Channel user packet but not immediately,
4674 ie. it was put to queue. The order of packets in the router
4675 was that Channel Key packet was first and Remove Channel User
4676 packet was second, even though they were encrypted in the
4677 reverse order. For this reason, MAC check failed. Now, this
4678 is fixed by not sending the Channel Key packet immediately but
4679 putting it to queue. However, this is more fundamental problem:
4680 packets that are in queue should actually not be encrypted
4681 because packets that are sent immediately gets encrypted
4682 actually with wrong IV (and thus MAC check fails). So, packets
4683 that are in queue should be encrypted when they are sent to
4684 the wire and not when they put to the queue.
4686 However, the problem is that the current system has not been
4687 designed to work that way. Instead, the packet is encrypted
4688 as soon as possible and left to the queue. The queue is then
4689 just purged into wire. There won't be any fixes for this
4690 any time soon. So, the current semantic for packet sending
4693 o If you send packet to remote host and do not force the send
4694 (the packet will be in queue) then all subsequent packets to the
4695 same remote host must also be put to the queue. Only after the
4696 queue has been purged is it safe again to force the packet
4699 o If you send all packets immediately then it safe to send
4700 any of subsequent packets through the queue, however, after
4701 the first packet is put to queue then any subsequent packets
4702 must also be put to the queue.
4704 Follow these rules and everything works fine.
4706 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Added new function silc_server_remove_clients_by_server to
4709 remove all client entries from ID list when the server connection
4710 is lost. In this case it is also important to invalidate all
4711 client entires as they hold the invalid server entry. This
4712 fixes fatal bug when server has lost connection and will reconnect
4715 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Made some sanity checks to silc_server_daemonise like to check
4718 whether the requested user and group actually exists.
4720 * Added sanity check to SKE's silc_ske_responder_finish to check
4721 that the public and private key actually is valid.
4723 * Invalidate the client's nickname when receiving Replace ID
4724 packet and the Client ID is being replaced. This means that the
4725 server will query the nickname if someone needs it (client)
4728 * Sort the ID Cache in client library when the ID Cache data
4729 has changed (needs sorting).
4731 * Do not allow for SILC client to create several connections to
4732 several servers. The client does not support windows right now
4733 and generating multiple connections causes weird behaviour.
4735 Irssi-silc client does support windows and can handle several
4736 connections without problems, see: www.irssi.org and SILC plugin.
4738 * Fixed some places where client was added to the IDList. The
4739 rule of thumb is following (in order to get everything right):
4740 If the client is directly connected local client then the
4741 `connection' argument must be set and `router' argument must be
4742 NULL to silc_idlist_add_client function. If the client is not
4743 directly connected client then the `router' argument must
4744 bet set and the `connection' argument must be NULL to the
4745 silc_idlist_add_client function.
4747 * The funtion silc_server_packet_send_local_channel actually did
4748 not check whether the client was locally connected or not. It
4749 does that now. Fixed a bug related to LEAVE command.
4751 * Fixed Remove Channel User payload parsing bug in server's
4752 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4754 * The server's silc_server_save_channel_key now checks also the
4755 global ID list for the channel as it might not be in the local
4756 list. Fixed a bug related to LEAVE command.
4758 * Is this the end of the [<unknown>] buglet that has been lurking
4759 around for a long time? A little for loop fix in server's
4760 silc_server_command_whois_parse that is used by both IDENTIFY
4761 and WHOIS command. At least, this was a clear bug and a cause
4762 of one type of [<unknown>] buglet.
4764 * WHOIS and IDENTIFY commands call the function
4765 silc_server_command_[whois/identify]_check function even if
4766 we are not router server.
4768 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added --with-gmp configuration option. If set the GMP
4771 is always compiled in the SILC source tree. If not set then
4772 it is checked whether the system has the GMP3 installed. If
4773 it has then the GMP won't be compiled (the system's headers
4774 and library is used), if it doesn't have it then the GMP is
4775 compiled in the SILC source tree.
4777 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Changed RSA private exponent generation to what PKCS #1
4780 suggests. We try to find the smallest possible d by doing
4781 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4782 not security fix but optimization.
4784 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Added new config entry [Identity] to fork the server and run
4787 it as specific user and group. A patch from Bostik.
4789 * Imported Dotconf configuration library into lib/dotconf.
4790 This will be used to create the SILC configuration files later.
4791 It will appear in the distsribution after this commit.
4793 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * A big code auditing weekend happening. Auditing code for
4796 obvious mistakes, bugs and errors. Also, removing any code
4799 Removed files for being obsolete:
4801 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4802 inline in the file lib/silcutil/silcbuffer.h)
4804 o lib/silcutil/silcbufutil.c (the header has inline versions)
4806 Changed code to fix possible error conditions:
4808 o The buffer formatting routines now check that the destination
4809 buffer really has enough space to add the data. This applies for
4810 both buffer formatting and unformatting
4811 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4812 unformatting was changed to accomodate following rules:
4813 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4814 sent to the function while XXX_*STRING will not allocate or copy
4815 the data into the buffer. Instead it sets the pointer from the
4816 buffer into the pointer sent as argument (XXX_*STRING used to
4817 require that the pointer must be allocated already). This change
4818 makes this whole thing a bit more consistent and more optimized
4819 (note that the data returned in the unformatting with XXX_*STRING
4820 must not be freed now). The routines return now -1 on error.
4822 o Tried to find all code that use buffer_format and buffer_unformat
4823 and added return value checking to prevent formatting and
4824 especially unformatting errors and possible subsequent fatal
4827 o Changed ske->x and ske->KEY to mallocated pointers in
4828 lib/silcske/silcske.h. Fixed possible data and memory leak.
4830 o Added return value checking to all *_parse* functions. Fixed
4831 many memory leaks as well.
4833 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4834 so that buffer overflows would not happen. All code now also
4835 checks the return value as it can fail.
4837 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Added reconnection support to server if the normal server looses
4840 its connection to the router (for example if router is rebooted).
4841 The server performs normal reconnection strategy implemented
4842 to the server. Affected file silcd/server.c.
4844 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added new packet type SILC_PACKET_SET_MODE that is used to
4847 distribute the information about changed modes (for clients,
4848 channels and clients channel modes) to all routers in the
4849 network. Updated the protocol specification accordingly.
4851 Added functions into silcd/packet_send.c and
4852 silcd/packet_receive.c: silc_server_send_set_mode,
4853 silc_server_set_mode.
4855 Added new files silcmode.[ch] into lib/silccore that implements
4856 the encoding and decoding of Set Mode Payload. Added new type
4857 SilcSetModePayload. Moved the definitions of different modes
4858 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4860 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Oops, a little mistake in server's connection authentication
4863 protocol. The protocol is not ended with FAILURE but with
4864 SUCCESS if the authentication is Ok. :) Affected file is
4867 * Implemented NICK_CHANGE notify handling in server in the file
4868 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4869 the local clients on the channel. After the changing nickname
4870 in router environment snhould work and the [<unknown>] nickname
4871 should appear no more.
4873 The silc_server_replace_id function that receives the Replace ID
4874 payload now sends the NICK_CHANGE notify type also in the file
4875 silcd/packet_receive.c
4877 * Changed WHOIS and IDENTIFY command to support the maximum amount
4878 of arguments defined in protocol specs (3328 arguments). This
4879 fixed a bug that caused problems when there were more than three
4882 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added extra parameter, command identifier, to the
4885 silc_client_send_command so that explicit command identifier
4888 Changed that ID list routines uses specific command identifier
4889 when sending WHOIS/IDENTIFY requests to the server so that they
4890 can be identified when the reply comes back.
4892 Affected files lib/silcclient/command.[ch],
4893 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4895 * Added `sender' argument to silc_server_packet_send_to_channel
4896 to indicaet the sender who originally sent the packet to us
4897 that we are now re-sending. Ignored if NULL. Affected file
4898 silcd/packet_send.[ch].
4900 * Added some server statistics support in silcd/server_internal.h
4901 SilcServerStatistics structure and around the server code. Also
4902 send some nice statistics information when client is connecting
4905 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Fixed channel ID decoding in server's JOIN command reply in
4908 silcd/command_reply.c
4910 * Fixed braodcasting of replace ID payload to not to send it if
4911 we are standalone server in silcd/packet_receive.c.
4913 * Fixed all channel message sending routines to not to send
4914 packets to clients that has router set, since they are routed
4915 separately in the same function earlier. Affects file
4916 silcd/packet_send.c and all channel packet sending functions.
4918 * In USERS reply, res_argv[i] are not allocated, the table
4919 is allocated. Thus changed that free the table, not its
4922 * In server's whois_check and identify_check if the client is
4923 locally connected do not send any WHOIS commands - they are not
4926 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Fixed some minor bugs in client when sending WHOIS command. The
4929 arguments was in wrong order.
4931 * Removed statis function add_to_channel from server in
4932 silcd/command.c that was previously used with the joining but
4935 * Tested USERS command in router environment successfully with two
4936 routers, two servers and two clients.
4938 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Reorganized the USERS command and command reply in client library
4941 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4942 When the command is given by user we register a pending command
4943 callback that will reprocess the command after the reply has been
4944 received from the server. When reprocessing the packet we then
4945 display the information. Thus, the USERS information is displayed
4946 now in the command callback instead of in the command reply
4947 callback. The processing of the command is same as previously
4948 when server has sent the command reply in the JOINing process.
4950 * Added to USERS command in silcd/command_reply.c to join the client,
4951 we didn't use to know about, to the channel after we've created
4952 a client entry for it. Also, for clienet we did know already still
4953 check whether it is on the channel or not and add it if not.
4955 * Removed silc_server_command_join_notify as the function and its
4958 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Changed the client's pending command handling to the same as the
4961 server's pending command handling. It is also now possible to
4962 execute command reply functions from other command reply
4963 function as the function callbacks for commands and command
4964 replies are one and same. The pending commands are not static
4965 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4966 in client connection context. Thus, pending commands are server
4967 connection specific as it is convenient.
4969 Changed the function silc_client_command_pending and
4970 silc_client_command_pending_del and added new function
4971 silc_client_command_pending_check. Removed the
4972 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4975 * Added cmd_ident, current command identifier, to the client
4976 connection context in lib/silcclient/client.h to keep track on
4977 command identifiers used in command sending. Client's command reply
4978 function handling now supports the mandatory command identifiers.
4980 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4981 funtions in client to fully support pending command callbacks.
4983 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4984 as one of the arguments to the application in the command reply
4987 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4988 before first releasing SILC but came back. Now it is removed again
4989 and should come back nomore. The FORWARDED flag was used only
4990 by the JOINing procedure by forwarding the command packet to router.
4991 Now, the JOINing procedure has been changed to more generic (due
4992 to various router environment issues) and FORWARDED is not needed
4993 anymore for anything. The protocol specification is yet to be
4996 Now, removed silc_server_packet_forward from server and the flag
4997 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4999 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Renamed NAMES command to USERS command. The NAMES was named that
5002 due to historical reasons. Now it is renamed. Also, rewrote
5003 parts of the USERS command. The nickname list is not sent anymore
5004 by the server. Only Client ID and mode lists are sent in the USERS
5005 command. Changed this also to the protocol specification.
5007 The client now resolves the names and stuff after it receives
5008 the USERS list from the server when joining to the channel.
5010 * WHOIS and IDENTIFY commands has been changed to support multiple
5011 Client ID's per command. One can now search for multiple users
5012 in the network by sending only one WHOIS or IDENTIFY command.
5013 Changed the code and the protocol specifications.
5015 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5016 uses silc_server_command_whois_parse to parse the request. */
5018 * If normal server, do not parse the WHOIS and IDENTIFY requests
5019 before sending it to the router. Saves some time.
5021 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Fixed JOIN command on client library. Wrong number of arguments
5024 used to crash the client.
5026 * Added silc_server_channel_has_global function to check whether
5027 channel has global users or not.
5029 * Added silc_server_channel_has_local function to check whether channel
5030 has locally connected clients on the channel.
5032 * The silc_server_remove_from_one_channel now checks whether the
5033 channel has global users or not after given client was removed from
5034 the channel. It also checks whether the channel has local clients
5035 on the channel anymore. If it does not have then the channel entry
5036 is removed as it is not needed anymore.
5038 * The silc_server_notify now checks on JOIN notify whether the joining
5039 client is one of locally connected or global. If it is global then
5040 the channel has now global users on the channel and that is marked
5041 to the channel entry. Also, it now saves the global client to
5042 global list who is joining and JOINs it to the channel. This is
5043 for normal server, that is.
5045 Changed silc_server_send_notify_on_channel,
5046 silc_server_packet_relay_to_channel and
5047 silc_server_packet_send_to_channel check if we are normal server
5048 and client has router set (ie. global client) do not send the
5049 message to that client, as it is already routed to our router.
5051 * Implemented LEAVE notify type handling in silc_server_notify
5054 * Tested LEAVE command in router environment successfully. Tested
5055 with two routers, two servers and two clients.
5059 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5061 * Implemented SIGNOFF notify type handling in silc_server_notify
5064 * silc_server_remove_id now removes the client entry from all channels
5065 it has joined and thusly sends SIGNOFF notify type.
5067 * Rewrote the NAMES list generation in server by removing two excess
5068 loops. The lists are created now inside one loop.
5070 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * silc_server_remove_channel_user checks now also global list
5073 for channel and client.
5075 * silc_server_new_channel_user checks now both local and global
5076 list for channel and client. Fixed a bug in client id decoding.
5077 Used to decode wrong buffer.
5079 * silc_server_channel_message checks now both local and global
5080 list for channel entry.
5082 * Tested channel joining (hence JOIN) in router environment
5083 successfully. Tested with two routers, two servers and two
5086 * Tested channel message sending in router environment successfully.
5088 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Added silc_server_save_channel_key into server.[ch] to save the
5091 received channel key in Channel Key payload processing. It is
5092 also used in JOIN command reply handling.
5094 Equivalent function silc_client_save_channel_key added into
5095 client.[ch] into client library.
5097 * Changed JOIN command reply to send information whether the channel
5098 was created or not (is existing already) and the channel key
5099 payload. Changed protocol specs accordingly.
5101 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5102 the request was sent by ID and not by nickname. Crashed on
5105 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5108 now correctly save the received data.
5110 * silc_server_free_sock_user_data now notifies routers in the
5111 network about entities leaving the network.
5113 At the same time implemented functions silc_server_remove_id
5114 and silc_server_send_remove_id to receive and send REMOVE_ID
5115 packets. The packet is used to notify routers in the network
5116 about leaving entities. The ID removed will become invalid in
5119 * Added function silc_idlist_del_server into server. Removes and
5120 free's server entry from ID list.
5122 * silc_server_private_message function now checks, if we are router,
5123 that the destination ID really is valid ID, naturally.
5125 * In router when NEW_ID packet is received (for new client) the
5126 hash of the Client ID is saved in the ID Cache but the
5127 client->nickname is set to NULL, instead of putting the hash
5130 IDENTIFY command now also checks that client->nickname must be
5131 valid. If it is not if will request the data from the server who
5132 owns the client. Added new function
5133 silc_server_command_identify_check.
5135 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5136 to set the command to already allocated Command Payload.
5138 * Tested private message sending in router environment with two
5139 routers, two servers and two clients. Fixed minor bugs and now
5142 * Fixed segfault from client's NAMES command. Used to crash if
5145 * Forwarded packets must not be routed even if it is not destined
5146 to the receiver. Changed server code comply with this.
5148 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Added `require_reverse_mapping' boolean value to ServerParams
5151 structure. If TRUE (not default) the server will require that
5152 the connecting host has fully qualified domain name.
5154 If the reverse mapping is not required and hostname could not be
5155 found the IP address is used as hostname.
5157 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Implemented version string checking to both client and server.
5160 The check is incomplete currently due to the abnormal version
5161 strings used in development version of SILC.
5163 * Changed all command functions in server to use the new
5166 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Changed char *data to unsigned char *data in ID Cache system to
5169 support binary data as ID Cache data. Changed code to support
5170 binary data in lib/silccore/idcache.c.
5172 * Renamed silc_server_packet_relay_command_reply to
5173 silc_server_command_reply as it is normal packet receiving
5174 function. Rewrote the function to accept command replys for
5175 servers and not only for clients.
5177 * Mark remote router always as registered server if we are connecting
5178 to it. Otherwise, commands sent by the router to us are ignored.
5180 * All ID List find routines now returns the ID Cache Entry pointer
5181 as well if requested.
5183 * WHOIS command works now in router environment, tested with two
5184 routers, two servers and two clients.
5186 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5187 in router environment (as it is almost equivalent to WHOIS) but
5188 hasn't been tested thoroughly. Added new functions:
5190 silc_server_command_identify_parse
5191 silc_server_command_identify_send_reply
5192 silc_server_command_identify_from_client
5193 silc_server_command_identify_from_server
5195 * Disabled route cache adding because adding two different ID's with
5196 same IP replaces the old cache entry thus giving wrong route.
5197 The entry->router->connection is always the fastest route anyway
5198 so route cache may not be needed. Of course, new routes maybe
5199 established after receiving the ID when the entry->router->connection
5200 might not be anymore the most optimal.
5202 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Add route cache for received ID for fast routing.
5206 * Added silc_server_packet_route to route received packet on router
5207 that is not destined to us.
5209 * Renamed silc_server_get_route to silc_server_route_get.
5211 * Added id_string and id_string_len fields into SilcServer to
5212 include encoded ServerID for fast comparing without excess
5213 encoding of the ID's.
5215 * Cleaned up WHOIS command on server side. Added following static
5218 silc_server_command_whois_parse
5219 silc_server_command_whois_check
5220 silc_server_command_whois_send_reply
5221 silc_server_command_whois_from_client
5222 silc_server_command_whois_from_server
5224 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5225 arguments in command replies. All command functions should be
5226 updated to use this macro.
5228 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Minor typo fixes on command reply handling on server.
5232 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Added silc_server_command_add_to_channel internal routine to add
5235 the client to the channel after router has created the channel and
5236 sent command reply to the server.
5238 * Added generic silc_server_send_command to send any command from
5241 * Use static buffer with ID rendering instead of duplicating data.
5243 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Fixed a channel user mode bug when joining to a channel server gave
5246 everybody channel founder rights, oops.
5248 * We mark ourselves as the router of the incoming server connection
5249 if we are router ourselves. This way we can check in some packet
5250 sending functions whether it is locally connected server. For
5251 incoming router connections we put NULL.
5253 * For router sending packets locally means now always sending the
5254 packet cell wide; to local clients and local servers. For normal
5255 server sending packet locally means sending it to only local
5258 * Fixed the JOIN command to really work in router environment. If the
5259 channel is created it is always created by the router. Router is
5260 also responsible of making the initial joining to the channel,
5261 sending JOIN notify to the sending server and distributing
5262 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5263 does not exist server doesn't do anything else but forward the
5264 command to the router which performs everything.
5266 * Added silc_server_send_channel_key function to send the Channel Key
5269 * Added silc_server_create_channel_key to create new channel key. The
5270 channel key is now re-generated everytime someone joins or leaves
5271 a channel, as protocol dictates. Note: channel->key_len is the
5274 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5277 packet_receive.[ch] to separate packet sending and receiving
5278 routines. The server.[ch] now includes everything else including
5279 actual packet processing (writing and reading data) and other
5282 Renamed silc_server_private_message_send_internal to
5283 silc_server_send_private_message. The routine is still though
5284 used only to relay private messages as server does not send
5285 private messages itself.
5287 Renamed silc_server_new_channel to silc_server_create_new_channel
5288 and added new function sicl_server_new_channel that handles the
5289 incoming New Channel packet. Added also new sending function
5290 silc_server_send_new_channel to send New Channel Payload.
5292 * Added new function silc_server_notify to process incoming notify
5293 packet to the server/router. Server may then relay the notify
5294 to clients if needed.
5296 * Added new function silc_server_new_channel_user to process incoming
5297 New Channel User packet. Router will redistribute the packet and
5298 send JOIN notify to its local clients and locally connected servers
5299 if needed. Normal server will send JOIN notify to its local client
5300 on same channel when received this packet. Added also corresponding
5301 sending function silc_server_send_new_channel_user to sent the
5304 * Added boolean route argument to send_notif_to_channel and
5305 packet_send_to_channel functions to attempt to route the packet
5306 if it is TRUE and send only locally if it is FALSE.
5308 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * silc_server_replace_id now broadcasts the received replace ID
5311 packet if it is not broadcast packet already. The router must
5312 broadcast to inform other routers about changed ID.
5314 * Added backpointer to server's router into SilcServer context in
5315 silcd/server_internal.h.
5317 * Fixed silc_server_packet_broadcast to send correct broadcast
5320 * The channel key is now distributed to the local client as soon
5321 as it is received from the router (in router environment) so that
5322 no other packet may be sent for the channel until client has
5325 * silc_server_remove_channel_user now broadcasts the received
5326 Remove Channel User packet if it is not broadcast packet already.
5327 The router must broadcast to inform other routers about removed
5330 * Added users field into SilcPacketContext that is a reference count
5331 of the context. One can increase the reference count by calling
5332 silc_packet_context_dup which is now changed to just increase the
5333 reference count instead of duplicating the data. The reference
5334 count is decresed by calling silc_packet_context_free that will
5335 free the data after the reference count hits zero.
5337 For now on the packet context and everything allocated into it
5338 (including the raw packet from network) must be freed by calling
5339 the new silc_packet_context_free function. Added also new function
5340 silc_packet_context_alloc that must be used now to allocate the
5341 context. This also means that if a routine is asynchronous from
5342 silc_[client/server]_packet_parse_type the packet context must
5343 be duplicated by calling silc_packet_context_dup. Otherwise it
5344 gets free'd after silc_[client/server]_packet_parse_type returns.
5345 Also, one must remember that if packet is duplicated then its
5346 reference count must be decresed by calling the free function as
5347 many times as it was duplicated.
5349 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5350 from both client and server.
5352 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Made joining to a channel working in router environment.
5356 * Cleaned up JOIN command on server side and create function
5357 silc_server_command_join_channel internal routine to make the
5360 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Changed silc_command_pending list to SilcDList. Also, added
5363 `ident' field to SilcServerCommandPending structure to identify
5364 the reply and to call correct callback.
5366 Added silc_server_command_pending_check function to replace the
5367 corresnponding macro. The silc_command_pending list is not
5370 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5371 to set identifier to previously allocated Command Payload. It
5372 is used to set identifier for command when resending Command
5375 * Added silc_command_payload_encode_payload to encode Command
5376 Payload buffer from SilcCommandPayload structure.
5378 * Added silc_argument_payload_encode_payload to encode Argument
5379 payload buffer from SilcArgumentPayload structure.
5381 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Changed WHOIS command to support router connection on server side.
5384 The whois request is always sent to router unless the server is
5385 standalone server. After server has received the reply from the
5386 router will it send the reply to the client.
5388 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5389 broadcast received broadcast packet. The function is used only
5390 by router. The broadcast packet is always sent to the router's
5393 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5394 render given ID to printable string, for log files for example.
5396 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Made basic router to router connections working. At least they
5399 can now connect to each other but nothing really works the way
5400 they are supposed - yet.
5402 * Added new initiator token to RouterConnection configuration
5403 file in silcd/serverconfig.[ch]. It is used to tell whether we
5404 are the initiator to the remote router or whether we'll expect
5405 the other end to connect.
5407 * Moved registering of listener task to silc_server_init, hence
5408 the server starts listenning as soon as it is run, even if it
5409 does not have connections to other routers. Let's see how well
5412 * Changed default connection retry timeouts for more suitable in
5415 * Removed cipher and such arguments from silc_idlist_add_client
5416 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5417 Added new function silc_idlist_add_data to add the keys and stuff
5420 * Added SilcIDListData structure and added it to SilcClientEntry
5421 and SilcServerEntry as their first field in the structure. This
5422 way we can explicitly cast the ID entries to the SilcIDListData
5423 structure and get common data for the entries. In past, we had
5424 to first check what type of connection it is and then cast it to
5425 correct ID entry type. Now, we can directly cast the opaque
5426 pointer to the SilcIDListData (no matter what ID entry it actually
5427 is) and get the data needed.
5429 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5432 in some circumstances even if threre were timeout tasks, though not
5433 IO tasks, but tasks anyway. Now fixed.
5435 * Defined SilcServerConnection structure to hold connection specific
5436 stuff about directly connected servers and routers. The definition
5437 is currently in silcd/server_internal.h. I thought about having
5438 a bit more important role fro this struct but for now it is used
5439 only when connecting to other server (or router actually).
5441 * Added connecting retry support in server when connecting to
5442 router(s). The retry feature implement exponential backoff
5443 algorithm. Also, added SilcServerParams structure to hold default
5444 parameters for server. For now, it include these retry settings
5445 and are hard coded. After server is moded to be as Silc Server
5446 Library this structure will be more important.
5448 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Changed client librarys channel->clients table to SilcList and
5451 changed code accordingly.
5453 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Changed client's channel table to SilcList and changed code
5456 accordingly. Also changed SilcChannelClientEntry to include back-
5457 pointer to the channel so that client entry can use that structure
5458 as list as well and we have fast cross-reference to the channel.
5459 This change dramatically decreased the complexity of channel
5460 handling with client entry and vice versa (removed one extra
5461 loop when searching for channel entry from many functions).
5463 * Changed server->sim from table to SilcDList and changed code
5466 * NAMES command can now be used from user interface. It will show
5467 the user list on the channel, neatly.
5469 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5470 Code now saves realname of the user if it becomes available.
5472 * Renamed configure.in to configure.in.pre and made ./prepare
5473 script to automatically add correct version string to
5474 configure.in which it creates from configure.in.pre.
5476 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * NAMES command reply now shows users mode with the nickname when
5481 * Moved silc_client_ch[u]mode[_char] functions from
5482 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5483 place sucks, they are utility functions and should be in some
5486 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5488 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5491 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added TRQ (efficient deque and list library) into lib/trq. This is
5496 a very good list library that is currently used in the SILC. Defined
5497 SilcList API over the library because I didn't like the API very
5498 much. See lib/trq/silclist.h for the API and examples of how to
5499 use the API. Fixed various places in the code to use the new
5500 SilcList API. The SilcList is meant for lists that has a structure
5501 already defined as a list. It is not suitable to add just some
5502 context to the list (in TRQ, the context is the list actually).
5504 So, I defined SilcDList that can be used for the purpose where
5505 predefined list structure does not exit. This can be used as
5506 such list. Now some context just can be added to the SilcDList.
5507 Currently this list is not used in the SILC just yet, though there
5508 are a lot places where this can replace dynamically allocated
5509 tables and I will fix these places, later, to use SilcDList.
5510 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5511 and use TRQ internally).
5513 Also fixed some annoying warning messages that the original TRQ
5514 code generated. Also minor changes to TRQ's Makefile.in.
5516 * Added support for querying by Client ID to both WHOIS and
5517 IDENTIFY commands into server, as required by the protocol.
5519 * Removed method function pointers from SilcBuffer structure. They
5520 weren't used to anything and just increased the context size for
5521 no good reason. This change also made silc_buffer_alloc and
5522 silc_buffer_free functions inline functions.
5524 * Disabled command flooding detection support until it's fixed so
5525 that it accepts commands in but does not execute them more than once
5528 * Added silc_net_localhost(), to return local hostname, into
5529 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5530 that must be initialized before calling silc_client_init.
5532 * Added new function: silc_server_send_notify_on_channels to send
5533 notify messages to all channels client has joined. It is assured
5534 that the message is sent only once per client.
5536 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5537 lib/silcutil/silcutil.[ch] as silc_format function. The new
5538 function is generic and is used by server as well, not only by
5539 the logging routines.
5541 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5542 the provided version string was not acceptable. Added new function:
5543 silc_ske_check_version into lib/silcske/silcske.h. The function
5544 must be implemented by the application (client or server) and it
5545 does not reside in the SKE library. The function checks the version
5546 string remote end sent.
5548 * Added back pointers (to opaque context and to SilcSocketConnection)
5549 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5551 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5552 duplicate packet context structure.
5554 * Changed `notify' client operation to send same arguments as client
5555 receives from server except for ID's. ID's are mapped to correct
5556 ID entry and that is returned. Also, if channel entry is not sent
5557 by server but the notify is for channel the channel entry is sent
5558 to application (otherwise application doesn't know that it is for
5559 channel (library gets it from packet's Destination ID)).
5561 * Added silc_client_remove_from_channels into client library to
5562 remove a client from all channels it has joined to. Used when
5563 received SIGNOFF notify from server. Added also new function
5564 silc_client_replace_from_channels to replace old ID entry with
5565 new ID entry on all channels. Used when received NICK_CHANGE
5568 * Fixed ID Cache list handling in silc_idlist_get_client in
5569 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5570 to get (or query) client by ID.
5572 * Updated TODO list.
5574 * Added connection authentication status message defined by the
5575 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5576 support for these into the code in client and server side.
5578 * Added generic function silc_client_send_command to send any command
5579 with variable argument list. Application should use this function
5580 to send commands if the command functions provided by the library
5581 does not suite for the application's user interface needs.
5583 * Added new `failure' client operation. Application is notified about
5584 received failure packet if client is executing a protocol. In this
5585 case the protocol's execution has failed.
5587 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5588 is required by the protocol.
5590 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5591 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5594 * Added status flag to SilcSKE object to indicate realtime status
5595 of the SKE protocol.
5597 * Application receives now exactly same command reply arguments as
5598 the library receives from server. However, if ID is received the
5599 corresponding ID entry is returned to the application (eg. Client
5600 ID is mapped to correct SilcClientEntry entry and that is returned).
5601 Changed command_reply client operation due to this change.
5603 * Changed all ID's in commands and in command replys as ID Payloads.
5604 Change affected both client and server side codes.
5606 All ID's sent in SILC network (with execption of ID's in SILC
5607 Packet header) are sent in ID Payload to support variable length
5610 * Server now notifies nick changes and notifies all clients on
5611 the channels about the new nickname (about the new Client ID,
5614 * Implemented CMODE command to change channel modes. Supports all
5615 channel modes defined by the protocol specs except ban and invite
5616 lists. (Also, private channel key mode is supported but support for
5617 setting private channel key in client is missing, thus, this mode
5618 has no effect on client side (except that server requires that the
5619 client uses private channel key and normal channel traffic does not
5622 Also, invite mode works per se, but INVITE command does not work
5623 yet correctly, so you can set channel as invite only channel but
5624 inviting clients to the channel does not work (it is yet to be
5625 thought what's the best way to do it).
5627 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5628 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5629 Implemented CUMODE command to change user's mode on the channel.
5630 Supports all modes defined by the protocol specs.
5632 * Added NAMES command reply to return users modes on the channel.
5634 * Removed unnecessary and slow ciphers from lib/silccrypt.
5636 * Set SO_KEEPALIVE option to connection sockets by default.
5638 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5640 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5641 redefined the Notify Payload into protocol specs.
5643 * Added silc_id_payload_parse_id to get ID directly from raw
5646 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5649 accept searching by Client ID as well.
5651 * Added support for LEAVE and SIGNOFF notify types in client library.
5653 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5654 to parse ID Payload from raw data.
5656 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added flags parameter into silc_ske_assemble_security_properties
5659 function in lib/silcske/silcske.[ch].
5661 * Changed notify client operation to fit better for notify messages
5662 sent by server. The notify payload received from server is now
5663 passed to the application (after parsing it to SilcNotifyPayload).
5664 It is application's responsibility to retrieve the arguments
5665 from the payload and show the message the way it wants. The message
5666 sent by server is implementation specific.
5668 * Changed public keys to comply with the protocol specification.
5669 Old public keys are not supported anymore and are not compatible.
5671 * Removed nickname from Channel Payload as the latest draft removed
5672 it. The client must resolve the nickname from the NAMES command
5673 reply received when it joined the channel.
5675 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5677 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Fixed some errors in protocol specification drafts.
5681 * Created lib/silccore/silcnotify.c to implement Notify Payload
5682 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5683 generic payloads described by protocol specifications. The file
5684 includes implementations for ID Payload and Argument Payload.
5686 * Changed Command Payload implementation to use the new Argument
5687 Payload. Changed command_xxxx_payload to command_payload_xxxx
5688 to comply with SILC coding conventions.
5690 * Added suppport for Argument Payload handling in Notify Payload
5691 implementation as protocol requires it. Added the new support
5692 into server and client lib as well.
5694 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added support for multiple nicknames on same channel. [n] is
5697 added locally to the nickname if there are more than one same
5698 nicknames on the channel.
5700 * Server now sends all nicknames that matched WHOIS request.
5701 Client also shows the list received from server.
5703 * Added TOPIC command to client side. User can now set and show
5704 current topic on channel.
5706 * Added MOTD command to client and server. Also, server sends the
5707 motd when client connects to the server.
5709 * Changed version strings to comply ISO 8601.
5711 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Fixed protocol error handling in client library. It should now
5714 cope even if the SKE fails for some reason.
5716 * Made new protocol specification drafts for submitting to IETF.
5718 * Implemented TOPIC command to server in silcd/command.c.
5720 * Added two new notify types into lib/silccore/silcnotify.h:
5721 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5722 notify nickname change and topic setting/change on a channel.
5724 * API change of command_reply operation in client library. The
5725 application gets now the status type received from server as well.
5727 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5731 * Cras fixed and optimized the packet handling even further and
5732 it should work now. Minor change to the prototype of function
5733 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5735 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added new function into lib/silcutil/silcschedule.[ch]:
5738 silc_schedule_with_fd to select() a specified fd. The function
5739 returns after timeout expires or data arrives or goes. The
5740 function is used by packet routines to wait that all data is
5741 received from network.
5743 * Fixed data reading from network in lib/silccore/silcpacket.c.
5744 The code now assures that all data is read from the fd and then
5745 continues packet processing. This was a bug fix since the code
5746 used to drop some data in some circumstances.
5748 * Added new function into lib/silcclient/client.[ch]:
5749 silc_client_start_key_exchange to start key exchange after
5750 connection has been established to server. The code internally
5751 now uses this funtion but its main purpose was to provide it
5752 for applications that perform their own connecting. After
5753 application has created a connection it merely calls this
5754 function to start the key exchange between client and server.
5755 The library takes care of everything else after that.
5757 Updated also lib/silcclient/README to explain the usage of
5760 * Do not send to application information that connection has
5761 been established. Application gets notified it by connect
5764 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Applied cras's patch to add silc_schedule_one function. The
5767 function runs scheduler once and returns.
5769 * Fixed the scheduler after cras messed it up. The timeout
5770 handling works now as it's supposed to work.
5772 * Added into lib/silccore/ silcnotify.h to include notify
5773 message types support. Changed silc_server_send_notify*
5774 functions, in server.[ch], to support those new notify types.
5775 Added the support for the notify types into client library,
5776 as well. Added new notify client operation into ops.h in
5779 * Changed silc_server_packet_send_to_channel to send normal
5780 packets instead of just channel message packets. The function
5781 is now used to send the notify packets to channels. It is not
5782 used to send channel message packets anymore, as server never
5785 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5786 va_arg()s as it seems to require it nowadays. I guess, if SILC
5787 is compiled with older va_arg() the new code should work anyway.
5789 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Splitted core library. Core library (lib/silccore) includes
5792 now only SILC protocol specific core (and common) components.
5793 Created new utility library (lib/silcutil) that includes more
5794 generic purpose stuff. The stuff for util library was taken
5795 from the old core library. This was minor and easy split.
5797 * Created SILC Client Library (lib/silcclient) that includes
5798 implementation of the SILC client without user interface. This
5799 was major move from silc/ directory. The code has been changed
5800 so that it is transparent towards the user interface. The
5801 silc/ directory includes now the same user interface as before
5802 and it uses the new client library. Read lib/silcclient/README.
5803 Basicly, the client library performs everything else related
5804 to SILC except user interface handling. Also, configuration
5805 files are considered to be part of user interface and library
5806 does not handle them.
5808 This change also changed a lot of structures, function naming etc.
5809 Most important change was that SilcClientWindow object was
5810 renamed to SilcClientConnection in the client library. Created
5811 also new file lib/silcclient/ops.h. Also added new files
5812 silc/local_command.[ch] and silc/client_ops.[ch].
5814 All these changes were made to make it easier for user interface
5815 designers to create what ever user interface for the SILC client
5818 It is also expected that the server will be moved to lib
5819 directory as well and SILC Server Library will be created;
5820 sometimes in the future.
5822 * Removed Local commands from lib/silccore/silccommand.h as
5823 they are application specific and new client library does not
5824 handle any of those anymore.
5826 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5827 old client implementation in silc/.
5829 * Added support for callback functions in SILC_LOG_* macros.
5830 Application can now set its own callbacks that will be called
5831 instead of using the default functions that will always print
5832 the debug messages to stderr (or stdout). Also, debugging can
5833 now be disabled by setting silc_debug to FALSE and re-enabled by
5834 setting it to TRUE. Note, that logging will still work even
5835 if debugging is disabled.
5837 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5838 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5839 silc_log_reset_debug_callbacks.
5841 * To enable debugging in silc client one must give now -d
5842 option on command line.
5844 * Changed silc_schedule_init to automatically allocate task queues
5845 if they are not allocated before calling it.
5847 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Added GMP 3.1 into math library.
5851 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5854 a channel in SILC network. The packet is used by servers and
5855 routers to notify other routers that user has left a channel.
5856 This little feature was missing until now. Added the feature
5857 to protocol specification as well.
5859 Added functions: silc_server_send_remove_channel_user and
5860 silc_server_remove_channel_user into server.[ch].
5862 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5863 lib/silccore/silcpacket.h. However, they are not implemented
5866 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Fixed joining to a channel and sending channel messages
5869 between server and router. The channel message sending should
5870 now work inside a cell.
5872 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5874 * Fixed the private message sending between server and router.
5875 The private message sending should now work inside a cell.
5877 * Added silc_server_replace_id into server.[ch] to replace
5878 existing ID in the SILC network.
5880 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5881 and silc_idlist_replace_server_id into idlist.[ch] in server.
5883 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Fixed the server to server connections. Server can again now
5886 connect to router. Router to router connections probably does
5889 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added dynamic protocol registering support. Now protocols can
5892 registered and unregistered on the fly. Patch by cras.
5894 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Added lib/contrib directory to hold routines that some platforms
5897 don't have but are needed by SILC.
5899 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5900 into lin/contrib to provide getopt() and getopt_long() for
5901 those who don't have it.
5903 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Added AWAY command to client. When away message is set and
5906 client receives a private message packet the client automatically
5907 replies to the sender with the away message.
5909 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5910 bug seemed to be the cause of recent problems when compiling
5913 * Added version detection support to SKE protocol specification
5914 and added the new changes to the SKE implementation as well.
5915 There were other minor changes in the SKE protocol as well.
5917 Many changes in lib/silcske/silcske.[ch] and in
5918 lib/silcske/payload.[ch].
5920 * Added ^U functionality, clear input line. Patch from cras.
5922 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Mainly small bugfixes on core library. Fixed some debugging
5925 logging and buffer overflow in silclog.c.
5927 * Updated config.sub and config.guess on the distribution tree.
5929 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added command lagging support in server. Client may execute
5932 commands now only once in two seconds.
5934 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Optimized packet reception. MAC computation and checking is now
5937 also more optimized. A lot previously duplicated code is now
5938 used as generic by both client and server.
5940 * Fixed key pair generation in clientutil.c
5942 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Added into lib/silccore/silcbufutil.[ch] new function;
5945 silc_buffer_realloc.
5947 * Moved generic packet sending/encryption functions to
5948 lib/silccore/silcpacket.[ch] from client and server. Some
5949 rewriting of the functions.
5951 * Moved all generic packet reception/decryption functions to
5952 lib/silccore/silcpacket.[ch] from client and server. The
5953 packet processing is now much cleaner in both client and server.
5954 These were major changes in both client and server.
5956 * Created many common functions in server to do packet sending.
5957 Previously code were duplicated a lot, this has been removed
5960 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Rewrote major parts of the ID cache system. Don't know
5963 whether it is better now or not but at least the API is more
5966 * Major rewrite on ID cache stuff on client because of the ID
5967 cache API changes. Added idlist.c to client.
5969 * Also major rewrite on ID cache stuff on server as well.
5970 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5971 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5972 in hand, instead they are all put into the ID cache system now.
5973 All server_idlist_* routines uses ID cache now instead of
5974 traversing its own lists (those lists does not exist anymore).
5975 SilcIDList though still exists. Also, SilcXXXEntry's are
5978 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Finally made the SKE implementation compliant to the protocol
5981 specification. All mp integers are now binary encoded as
5982 opposed being HEX encoded.
5984 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5987 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5988 functions: silc_[encode/decode]_pem. Also added function
5989 silc_encode_pem_file to PEM encode with newlines ('\n') for
5992 * SILC public keys are now encoded either PEM or binary. Same
5993 option is for private keys as well. By default private keys
5994 are binary encoded and public keys PEM encoded. Silly HEX
5995 encoding were removed.
5997 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5998 function to create fingerprints.
6000 * Fixed a bug in SHA1; does not change the original data anymore.
6002 * Partly implemented INFO command on client and server side.
6003 Fixed CLEAR command. Changes to SERVER command; show current
6004 server(s) when giving command without arguments. Added
6005 VERSION command to client.
6007 * Added check to server that unregistered connections cannot
6008 execute commands (unless it is specificly allowed).
6010 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6012 * Fixed screen refresh.
6014 * Fixed channel joining bug from client. On some circumstances
6015 client tried to join to a channel it had already joined.
6017 * Added public key verification process into client's protocol.c.
6018 The client now verifies the public key from user and saves
6019 it into ~./silc/serverkeys/ directory.
6021 Added into: clientutil.[ch]: silc_client_verify_server_key.
6023 * Changed SKE protocol's silc_ske_initiator_finish function
6024 to accept callback function that verifies the received public
6025 key. Removed old silc_ske_verify_public_key function.
6027 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6030 silc_pkcs_private_key[_data]_set.
6032 * Made the password and public authentication more cleaner in
6033 server's protocol.c.
6035 * Removed historic and obsolete protocol `channel_auth' from
6036 both client and server.
6038 * Removed wrong way of sending command status messages from
6039 server to client in server's command.c. The old way violated
6040 protocol specification.
6042 Changes to silccore/silccommand.[ch]: removed
6043 silc_command_encode_status_payload -> not needed anymore,
6044 changed silc_command_encode_payload_va to accept extra
6045 argument on variable argument list. The argument type must
6046 now be provided to the function. Also, added new function:
6047 silc_command_encode_reply_payload_va which is same as
6048 normal command_encode_payload_va except command status type
6049 is provided as extra argument.
6051 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added ~./silc directory handling. The directory includes the
6054 public and private keys for the client.
6056 Added silc_client_check_silc_dir, silc_client_create_identifier
6057 and silc_client_load_keys.
6059 * Implemented SILC protocol compliant public key. Added public
6060 and private key saving to and loading from files.
6062 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6063 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6064 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6065 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6066 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6068 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6069 silc_pkcs_load_[public/private]_key.
6071 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6073 * Added silc_server_get_route (route.[ch]) to get connection
6074 data for the fastest route for given ID.
6076 * Implemented INVITE command on client and server. The command
6077 were re-defined in the SILC Protocol Specification and the
6078 implementation now complies with the specification.
6080 * Implemented PING command on client and server.
6082 * Implemented NAMES command on client and server. The server side
6083 supports currently only normal server not router server yet.
6084 Some changes to NAMES definition in SILC protocol specification.
6086 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Implemented LEAVE command on client and server.
6090 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6091 again. This change was made to the protocol as well. Server
6092 should not violate the protocol specification anymore.
6094 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6097 was tested. SOCKS4 was not but should work anyway.
