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

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

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

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

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

465 lib/silcutil/silcutil.[ch].
467 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Resolve the client info when received private message or
470 channel message for a client which nickname we don't know.
471 Affected files lib/silcclient/client_prvmsg.c and
472 lib/silcclient/client_channel.c.
474 * Do not crash in /KEY if client is not connected. Affected
475 file irssi/src/silc/core/silc-channels.c.
477 * Added SilcClientStatus field to the SilcClientEntry in the
478 lib/silcclient/idlist.h.
480 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
481 is incomplete and is being resolved, it won't be resolved
484 Make sure also that USERS command reply does not resolve
485 twice information. Affected file is
486 lib/silcclient/command_reply.c.
488 Make sure that silc_client_get_clients_by_list does not
489 resolve twice same information.
491 * Check for valid client->id in the silc_server_free_client_data.
492 Affected file silcd/server.c.
494 * Fixed /GETKEY nick@server not to crash if the server entry
495 is not found. Affected file lib/silcclient/command.c.
497 * Fixed the silc_server_check_cmode_rights to check the
498 requested modes correctly. Affected file silcd/command.c.
500 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
502 * Better checks for non-printable chars in nick added.
503 Affected file silcd/command.c.
505 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Call the silc_server_udpate_servers_by_server in the
508 primary router that comes back online in the backup resuming
509 protocol. Otherwise it routes packets wrong. Affected file
510 silcd/server_util.[ch], silcd/server_backup.c.
512 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
514 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
515 lib/silcutil/silcbuffmt.[ch].
517 * Redefined the SILC packet header to include the padding
518 length. Affected file lib/silccore/silcpacket.[ch].
520 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
521 length for maximum padding up to 128 bytes). Affected
522 file lib/silccore/silcpacket.h.
524 * Removed all backwards support for old 0.5.x MAC thingies.
525 The SILC packet header change makes it impossible to be
526 backwards compatible.
528 * Send the ENDING packet with timeout in the backup resuming
529 protocol. This is to assure that all routers has connected
530 to the primary router. Affected file silcd/server_backup.c.
532 * Changed the RNG to take the first IV from random data. It
533 used to take it from zero actually. Changed the RNG also
534 to use /dev/urandom during session. /dev/random is used
535 in initialization. Affected file lib/silccrypt/silcrng.[ch].
537 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
539 * Changed the SILC packet header to have the first two bytes
540 (the packet length) encrypted. Affected files aroung the
541 code tree, lib/silccore/silcpacket.[ch]. Removed the
542 SilcPacketCheckDecrypt callback. It is not needed anymore
543 since the silc_packet_receive_process will determine now
544 whether the packet is normal or special.
546 * Implemented the unidirectional MAC keys. Affected files
547 lib/silcske/silcske.c, silcd/protocol.c and
548 lib/silcclient/protocol.c.
550 * Implemented the packet sequence number to the MAC computation.
551 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
552 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,

555 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Allow backup router to announce servers. All servers
558 announced by backup router are added to the global list
559 automatically. Update hte server's socket to our primary
560 router also when backup router announces a server.
561 Affected file silcd/packet_receive.c.
563 * Do not update the client->router in the function
564 silc_server_udpate_clients_by_server if the client is on
565 global list. We might fail to find any specific server
566 for locally connected clients and local cell clients. They
567 should still use the `from' and not `to' as client->router.
568 This fixes backup router resuming protocol. Affected file
571 * Decrease channel statistics count only if the channel
572 deletion worked. Affected files are silcd/server.c and
575 * Added silc_server_update_servers_by_server to update origin
576 of all server entries. Used during backup router protocol.
577 Affected files silcd/server_util.[ch], silcd/server.c. and
578 silcd/backup_router.c.
580 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
581 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
582 silc_hmac_get_hash and silc_hmac_get_name. Affected file
583 lib/silccrypt/silchmac.c.
585 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
587 * Assure that router cannot reroute the same channel message
588 to the sender. Affected file silcd/packet_receive.c.
590 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Made better checks that the channel message is not sent
593 to the router it came from. Affected file is
594 silcd/packet_send.c. Fixed memory leak too.
596 * Announce informations for incoming router connection, but
597 only after checking if it is replaced by backup router.
598 Affected file silcd/packet_receive.c.
600 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
602 * Fixed the backup resuming protocol to work in multiple
603 router environment. Affected file silcd/server_backup.c.
605 * Route packet only to one router in the function
606 silc_server_packet_send_to_channel. Affected file is
609 * Fixed silc_server_send_notify_dest to set the broadcast
610 flag. Fixed the silc_server_send_notify_topic to actually
611 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
612 Affected file silcd/packet_send.c.
614 * Changed the SFTP Filesystem interface. Changed the
615 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
616 the filesystem operation function. The SilcSFTPFilesystem
617 is now a context that is allocated by all filesystem allocation
618 functions and it already includes the operations structure
619 and filesystem specific context. It is given as argument
620 now to the silc_sftp_server_start. This made the interface
621 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
622 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
624 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Changed the backup router adding and getting interfaces
627 in the server. The router that will be replaced by the
628 specified backup router is now sent as argument. Affected
629 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
632 * Added silc_net_addr2bin_ne to return the binary form of
633 the IP address in network byte order. Affected files
634 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
636 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
638 * Check for existing server ID in silc_server_new_server
639 and in silc_server_connect_to_router_final and remove the
640 old entry if it exists. Affected file silcd/packet_receive.c,
643 * Send the channel message always to only one router, either
644 in upstream or downstream. Affected file is
647 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
649 * Wrote the definition of the backup resuming protocol to the
650 protocol specification.
652 * Removed one redundant channel key generation from normal
653 server during joining procedure. Removed one redundant
654 channel key sending from server to router during joining
655 procedure. Affected file silcd/command.c.
657 * Made minor bugfixes to the backup router resuming protocol.
658 Affected file silcd/server_backup.c, server.c.
660 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Added --disable-asm configuration option. Affected files
663 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
666 * Implemented the backup resuming protocol that is used to
667 resume the primary router position in the cell after the
668 primary router comes back online. Affected files
669 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
670 and silcd/server_util.[ch].
672 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Sleep two (2) seconds after sending QUIT command to server.
675 Affected file lib/silcclient/command.c.
677 * Assure that if outgoing data buffer is pending do not force
678 send any data. Affected file silcd/packet_send.c.
680 * Assure that if outgoing data buffer is pending do not force
681 send any data. Affected file lib/silcclient/client.c.
683 * Implemented the backup router support when the primary router
684 goes down. The servers and routers can now use the backup
685 router as new primary router without loosing connectivity.
687 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
690 in the server to indicate disabled entry. All data read
691 from the connection will be ignored and no data is sent
692 for entry that is disabled. Affected files are
693 silcd/idlist.h, silcd/server.c.
695 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Created SFTP client and server test programs in the
698 lib/silcsftp/tests directory.
700 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
702 * Implemented memory filesystem (virtual filesystem) for
703 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
706 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
708 * Implemented the SFTP (SSH File Transfer Protocol) to the
709 lib/silcsftp. It includes SFTP client and SFTP server
712 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
714 * Moved lib/silccore/silcprotocol.[ch] to the
715 lib/silcutil library.
717 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
718 take variable argument list pointer as argument. Affected
719 file lib/silcutil/silcbuffmt.[ch].
721 * Added silc_buffer_set function that is used to set data
722 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
723 Affected file lib/silcutil/silcbuffer.h.
725 * Changed various routines in the core library to use the new
726 silc_buffer_set instead of allocating new buffer only for
729 * Added 64-bit value formatting and unformatting support to the
730 silc_buffer_[un]format routines. Affected file is
731 lib/silcutil/silcbuffmt.[ch].
733 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
734 to includes/bitmove.h.
736 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
738 * Fixed channel user mode saving in client library. Affected
739 file lib/silcclient/command[_reply].c.
741 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Defined the file transfer to the SILC Protocol. Added
744 new packet type SILC_PACKET_FTP and defined File Transfer
745 Payload. The mandatory file transfer protocol is SFTP
746 (SSH File Transfer Protocol). Affected file in addition
747 of the internet draft is lib/silccore/silcpacket.h.
749 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
750 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
751 is used as part of backup router protocol when the primary
752 router of the cell is back online and wishes to resume
753 the position as primary router.
755 * Redefined the MAC generation keys in the protocol. The
756 same key is not used anymore in both direction. Both
757 direction will now use different keys for sending and
758 receiving. This fixes a potential security flaw. This
759 change causes incompatibilities in the protocol.
761 * Redefined also the MAC computation from the packet.
762 An packet sequence number is now added to the MAC
763 computation. This prevents possible replay attacks against
764 the protocol. This change too causes incompatibilities
767 Added `sequence' field to the SilcPacketContext to hold
768 the current sequence number for the packet.
770 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
772 * Added `created' field to the SilcIDListData in the file
773 silcd/idlist.h to indicate the time when the entry was
776 * Added `created' field to the SilcChannelEntry too. Affected
779 * Added `creation_time' aguments to all the announcement functions
780 in the server. If it is provided then only the entries that
781 was created after the provided time frame are actually
782 announced. Affected file silcd/server.[ch].
784 * The protocol says that the Channel ID's IP address must be
785 based on the router's IP address. Added check for this in
786 the silc_server_new_channel when processing incoming New Channel
787 Payload. Affected file silcd/packet_receive.c.
789 * Print out the correct version with --version in SILC client.
790 Affected file irssi/src/silc/core/silc-core.c.
792 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Fixed WHOWAS command to check for completnes of the client
795 entry always, not just when the command is coming from client.
796 Affected file silcd/command.c.
798 * Added new function silc_server_packet_queue_purge to purge the
799 outgoing data queue to the network. After the function returns
800 it is guaranteed that the outgoing packet queue is empty.
801 Affected file silcd/packet_send.[ch].
803 * Purge the outgoing packet queue in the rekey protocol's final
804 callback to assure that all rekey packets go to the network
805 before quitting the protocol. Affected file silcd/server.c.
807 * Added silc_client_packet_queue_parse as similar function as
808 in server to the client library. The affected file is
809 lib/silcclient/client.c.
811 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Splitted silcd/server.c and created silcd/server_util.[ch]
814 for utility functions.
816 * Added new socket flag SILC_SF_DISABLED to indicate that the
817 connection is open but nothing can be sent to or received from
818 the connection. Affected file lib/silcutil/silsockconn.[ch].
819 The checking for disabled socket is checked in the low level
820 silc_socket_write and silc_socket_read functions.
822 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Allow only nicknames and channel names that fits into the
825 7-bit unsigned char ASCII set. Affected file silcd/command.c.
827 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
829 * When processing JOIN command reply in server check that if
830 the channel exists in our global list we'll move it the local
831 list. Affected file silcd/command_reply.c.
833 * Fixed the check whether client is joined on the channel already
834 in JOIN command. Affected file lib/silcclient/command.c.
836 * Fixed the JOIN command reply to check whether the channel
837 already exists. Affected file lib/silcclient/command_reply.c.
839 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Added silc_ske_status_string to map the SKE error numbers
842 to readable strings. The affected files are
843 lib/silcske/silcske[_status].[ch].
845 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Do not show the private channels on the WHOIS channel list
848 as it is not allowed by the protocol. The affected file is
851 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Assure that the packet length digged from the actual packet
854 is something sensible in the silc_packet_decrypt_rest_special
855 in lib/silccrypt/silcpacket.c.
857 * Free and NULL the allocated pointer in silc_hmac_alloc if
858 the HMAC allocation fails. The affected file is
859 lib/silccrypt/silchmac.c.
861 * Print the selected security properties to the log files in
862 the server. Affected file silcd/protocol.c.
864 * Add SKE's reference counter even if calling the completion
865 callback manually. Otherwise it goes negative, although it
866 does not cause any problems. The affected file is
867 lib/silcske/silcske.c.
869 * Remove the client entry with short timeout after giving the
870 KILL command. Affected file lib/silcclient/command.c.
872 * Fixed to send error reply in WHOIS and IDENTIFY commands in
873 case all found clients are already disconnected (WHOWAS would
874 found them) in the server. Affected file silcd/command.c.
876 * Update the last_receive (time of last data received) to be
877 updated only when received private or channel message so that
878 the idle time showed in WHOIS makes more sense.
880 * Added boolean field `valid' in to the SilcClientEntry in the
881 client library to indicate whether the entry is valid or not.
882 This fixes the nickname change bug on channel when changing
883 the nickname to be same than the old (like nick to Nick) the
884 nickname formatter doesn't set the new nick anymore to Nick@host.
885 Affected file lib/silcclient/idlist.[ch].
887 * Now actually fixed the nickname changing on disconnection.
888 Added new function silc_change_nick to the Irssi SILC Client.
889 Affected file irssi/src/silc/core/client_ops.c,
890 irssi/src/silc/core/silc-nicklist.[ch].
892 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Check that the public key exists in the GETKEY command before
895 trying to encode it. Affected file silcd/command.c.
897 * Print some notifications on received public keys with GETKEY
898 command in the Irssi SILC Client. Affected files are
899 irssi/src/fe-common/silc/module-formats.[ch],
900 irssi/src/silc/core/client_ops.c.
902 * Use IDENTIFY command to resolve the server information in the
903 GETKEY command instead of INFO command. Affected file
904 lib/silcclient/command.c.
906 * All command reply functions in the client library now calls
907 the pending command reply callbacks even if an error has
908 occurred. The server has done this a long time and now it was
909 time to move the client library to this as well. Now all
910 errors can be delivered back to the pending command reply
911 callbacks if necessary. Affected files are
912 lib/silcclient/command[_reply].[ch].
914 * Change the nickname on disconnection back to the username
915 because in reconnect the server will enforce it to it anyway.
916 Affected file irssi/src/silc/core/silc-servers.c.
918 * Fixed a config file parsing bug in the Irssi SILC client.
919 Affected file irssi/src/silc/core/clientconfig.c.
921 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
923 * When printing the channel mode on JOIN, verify that the
924 channel key and channel's HMAC are valid. Affected file
925 irssi/src/silc/core/client_ops.c.
927 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
930 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
931 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
933 * Removed channel key rekey task deleting from the function
934 silc_server_save_channel_key. Affected file silcd/server.c.
935 Added explicit timeout task context instead that is used to
936 delete the task if we are registering a new task before the
937 new task has elapsed.
939 * When channel key rekey occurs the client library now saves
940 the old channel key for a short period of time (10 seconds) and
941 is able to use it in case some is still sending channel
942 messages encrypted with the old key after the rekey. Affected
943 file lib/silcclient/[idlist.h|client_channel.c].
945 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
947 * Added check to the silc_server_new_id_real to not accept
948 new ID if it is the sender's own ID. Affected file is
949 silcd/packet_receive.c.
951 * Assure that we do not announce ourself or the one we've
952 sending our announcements when we're router and are announcing
953 servers to our primary router. Affected file silcd/server.c.
955 * Fixed silc_server_command_identify_check_client to assemble
956 correct WHOIS packet. It send corrupted WHOIS packet and
957 caused problem with router to router connections. Affected
958 file silcd/command.c.
960 Fixed also silc_server_command_whois_check the same way
961 as for the IDENTIFY command.
963 * Added new SilcIDListStatus to the server in the SilcIDListData
964 structure. The status now includes the current status of
965 the entry (like registered, resolved etc.). Affected file
966 silcd/idlist.[ch]. Defined a bunch of different status types
967 as well. This replaced the old boolean registered field as well.
969 Added resolve_cmd_ident field to the SilcClientEntry structure
970 too so that if the entry is for example being resolved so
971 another command may attach to the same pending command reply
972 without requiring to resolve the same entry again. This concept
973 should optimize the WHOIS and the IDENTIFY resolving under
974 heavy load by taking away unnecessary resolving for entries
975 that are being resolved already.
977 Added support for adding multiple pending commands for one
978 command idenfier. Affected file silcd/command[_reply].[ch].
980 * Fixed WHOIS and IDENTIFY save to remove the cache entry
981 before deleting the data. Otherwise the hash table will have
982 freed data in comparison functions. Affected file is
983 silcd/command_reply.c.
985 * Fixed silc_idlist_replace_client_id to add the new entry to
986 the cache with NULL nickname. Otherwise there will be invalid
987 memory as the nickname after the nickname is freed. Affected
988 file silcd/packet_receive.c.
990 * Fixed the silc_idlist_get_clients_by_hash. The entries was
991 saved into wrong slots because the previous number of entries
992 was not taken into account. Affected file silcd/idlist.c.
993 Fixed same thing in silc_idlist_get_clients_by_nickname too.
995 * If we are router and we receive JOIN notify to a channel that
996 does not have any users then notified client is marked as the
997 channel founder, as it is it. The affected file is
998 silcd/packet_receive.c
1000 * Added to the extended hash table API's table_del_*ext functions
1001 the destructor as argument too, so that the caller can decide
1002 which destructor to use or whether to use destructor at all.
1003 Affected file lib/silcutil/silchashtable.[ch].
1005 * Fixed ID Cache purging. It actually deleted the entries from
1006 the hash table after the data was freed. The hash table ended
1007 up comparing freed memory. The affected file is
1008 lib/silccore/silcidcache.c.
1010 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Fixed Irssi SILC client's KILL command's HELP syntax.
1014 * The USERS command now resolves the detailed user information
1015 if the userinfo field is missing. Affected file is
1016 lib/silcclient/command_reply.c.
1018 * Do not print error in silc_file_read if the read file does
1019 not exist. Just silently return NULL. Affected file is
1020 lib/silcutil/silcutil.c.
1022 * Fixed the silc_log_output to not wine about NULL filename
1023 and to not create some bogus " " filename. Affected file is
1024 lib/silcutil/silclog.c.
1026 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Fixed various printing bugs on the user interface in the
1029 Irssi SILC Client. Minor changes that were forgotten from
1032 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Fixed the configure.in.pre and the compilation and distribution
1035 environment to support the new autoconf 2.52. That version is
1036 now required to compile the CVS trunk.
1038 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1041 to generally parse user@fqdn format strings. Affected file
1042 lib/silcutil/silcutil.c.
1044 * Added nickname_format and nickname_force_format fields to the
1045 SilcClientParams structure. The first one defines the format
1046 for the nicknames that the library will enforce if the receives
1047 multiple same nicknames. The second one is boolean value and
1048 can be used to force the library to always enforce the format
1049 to the nicknames regardles whether there are multiple nicknames
1050 or not. This configurable formatting was employed to flexibly
1051 support accessing multiple nicknames from the user interface.
1052 The userinterface can now set the nicknames to what ever format
1053 they prefer. Affected file lib/silcclient/silcapi.h.
1055 Added function silc_client_nickname_format to the file
1056 lib/silcclient/idlist.c. It performs the nickname formatting.
1058 Added new field `hostname´ to the SilcClientEntry context.
1059 It holds the hostname of the client. Affected file is
1060 lib/silcclient/idlist.h.
1062 * Irssi SILC Client sets the nicknames in nick@hostn format.
1063 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1064 irssi/src/silc/core/silc-core.c.
1066 The WHOIS printing now also shows both the real nickname and
1067 the formatted nickname so that user knows how to access the
1068 user if there are multiple same nicknames cached. Affected
1069 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1070 printing formatting too to take the hostname now as a separate
1071 argument. The Affected file is
1072 irssi/src/fe-common/silc/modules-formats.[ch].
1074 * Changed the silc_client_get_clients_local to accept the formatted
1075 nickname as argument. It accepts the real nickname too but the
1076 formatted nickname can be used to find the true entry from
1077 multiple entries. Affected file lib/silcclient/silcapi.h and
1078 lib/silcclient/idlist.c.
1080 * Added nickname_format_parse field to the SilcClientParams.
1081 It is a callback function provided by the application to parse
1082 the nickname out of the formatted nickname string. The library
1083 calls it to get the nickname from the formatted string. Since
1084 the application generally knows better the format of the nickname
1085 string it parses it instead of the library, even though library
1086 encodes the formatted string. If the callback function is not
1087 provided then the library will use the string as is. The
1088 affected file is lib/silcclient/silcapi.h.
1090 * All the nickname strings passed to the client library in
1091 commands are now expected to be formatted nickname strings.
1092 If the command does not support the formatted nickname string
1093 it will assume that the sent string is the actual nickname.
1094 Affected file lib/silcclient/command.c.
1096 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Added public key authentication support to OPER and SILCOPER
1099 commands in the client library. Affected file is
1100 lib/silcclient/command.c.
1102 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Changed the get_auth_methdod client operation to be asynchronous.
1105 It can be async if the application resolves the authentication
1106 method from the server during the negotiation. Added new
1107 SilcGetAuthMeth completion callback that the application will
1108 call after resolving the authentication method.
1110 Added function silc_client_request_authentication_method that
1111 the application can use to resolve the authentication method
1112 from the server. Added also SilcConnectionAuthRequest callback
1113 that the library will call after the server has replied. The
1114 application can call this function if it does not know the
1115 current authentication method.
1117 Affected files are lib/silcclient/client.c and
1118 lib/silcclient/silcapi.h.
1120 * The Irssi SILC client now automatically resolves the authentication
1121 method incase any configuration information is not present (and
1122 currently there never is). The affected file is
1123 irssi/src/silc/core/client_ops.c.
1125 * Fixed public key authentication from the client library.
1126 Affected file lib/silcclient/protocol.c. Changed also the
1127 protocol specification about the public key authentication in
1128 the connection authentication protocol. The actual data to be
1129 signed is now computed with a hash function before signing.
1131 * Fixed the public key authentication from the server as well.
1132 Affected file silcd/protocol.c.
1134 * Removed the mlock()'s from the memory allocation routines.
1135 Affected file lib/silcutil/silcmemory.c. The ./configure does
1136 not check anymore for the mlock(). Affected file is
1139 * Fixed USERS command in server to allow the execution of the
1140 command for private and secret channels if the client sending
1141 the command is on the channel. Affected file silcd/command.c.
1143 * Fixed silc_client_get_clients_local to return the clients
1144 count correctly. It could return wrong value. Affected file
1145 lib/silcclient/idlist.c.
1147 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1150 types. The assembler optimizations seemed not to like 64-bit
1151 data types. The assmebler optimizations thus are now enabled
1152 also for BSD systems as opposed to only enable them for Linux.
1154 * Do not check for threads at all on BSD systems. Affected
1155 file configure.in.pre.
1157 * Removed -n and -h options from the Irssi SILC Client since
1158 they are not used in silc.
1160 * Fixed the prime generation to assure that the first digit
1161 of the generated random number is not zero since our conversion
1162 routines does not like number strings that starts with zero
1163 digit. If zero digit is seen the random number is regenerated.
1164 This caused some corrupted RSA keys when the zero first digit
1165 was met. Affected file lib/silcmath/silcprimegen.c.
1167 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Fixed WIN32 configuration in the ./configure script.
1170 Fixed to include xti.h on environments that has it.
1171 Patches by Carsten Ilchmann and andrew.
1173 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Changed the silc_id_create_client_id to be collision
1176 resistant. It is now assured that there cannot be created
1177 two same client ID's. I suspect that some weird bugs in
1178 the server were actually caused by duplicate Client IDs.
1179 Affected file silcd/serverid.[ch]. A router receiving
1180 new ID now also assures and informs the sending server
1181 if the ID caused collision.
1183 * Changed the silc_id_create_channel_id to also assure that
1184 there are no collisions.
1186 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Statement about ignoring the Mutual Authentication flag when
1189 performing rekey with PFS was a bit misleading. It is ignored
1190 if it was set in the initial negotiation, it cannot be even
1191 set in the rekey. Fixed in the ke-auth draft. Started the
1192 new versions of the protocol drafts in the doc/.
1194 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Fixed a bug in silc_client_command_identify_save when saving
1197 new channel information. The channel name was no duplicated
1198 and caused crash on exit. Affected file is
1199 lib/silcclient/command_reply.c.
1201 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Fixed the getkey command handling in the server. Send just
1204 empty OK reply to the sender if the key could not be fetched
1205 (but everything else was ok, like the key just was not available).
1206 Changed the public key parameter to optional in the protocol
1207 specs so that empty OK reply can be sent. Affected file
1210 Added a message to Irssi SILC client to tell to user if the
1211 server did not return a public key.
1213 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Fixed a channel key regeneration bug. It registered new
1216 timeout tasks exponentially until all system resources were
1217 used. Affected file silcd/server.c.
1219 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * Added the SILC Document generator to the scripts/silcdoc.
1222 It can be used to generate the Toolkit Reference Manual out
1223 of the source tree. Internally it will also use the RoboDoc
1224 generator now imported in util/robodoc.
1226 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Added couple of return's in rekey protocol if error orccurred
1229 during the protocol. The execution must be terminated.
1230 Affected file silcd/protocol.c. Also, terminate the protocol
1231 always with timeout.
1233 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * The client's Client ID was created initally from the wrong
1236 nickname (it could have been in format nick@host) in the
1237 silc_server_new_client. Affected file silcd/packet_receive.c
1239 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * Added some SILC_LOG_ERROR's to various error conditions
1242 if client could not be added to ID cache. Affected files
1243 silcd/packet_receive.c and silcd/server.c.
1245 * When client's sock->user_data is freed, NULL also the
1246 client->router and client->connection pointers. Added check
1247 for these pointers being NULL to various places around the
1248 code. Affected file silcd/server.c.
1250 * Added client->data.registered == TRUE checks to various
1251 places around the code to assure that unregistered client's
1252 are not handled when it is not allowed. Affected file
1255 * Added `bool registered' fields to all
1256 silc_idlist_[server|client]_get_* routines to indicate whether
1257 the fetched client needs to be registered or not. Affected
1258 file silcd/idlist.[ch].
1260 * Add your own entry as registered to the ID cache in the
1261 server. Affected file server.c.
1263 * Fixed a bug in silc_server_new_server. The SilcServer was
1264 set as the new server's context instead of SilcServerEntry.
1265 This naturally caused some weird bugs.
1267 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Do not delete the channel rekey task when adding it
1270 for in silc_server_create_channel_key.
1272 * Changed the silc_server_create_channel_key to return
1273 TRUE or FALSE to indicate the success of the channel key
1276 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Fixed MSVC++ project files and added missing files to
1279 Makefiles under win32/.
1281 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Do not add TCP_NODELAY flag if the operating system
1284 does not have it defined. Affected files are
1285 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1287 * Fixed buffer overflow from Irssi SILC Client. Affected
1288 file irssi/src/fe-common/core/themes.c.
1290 * Fixed double free in client library in the file
1291 lib/silcclient/client.c when disconnecting from server.
1293 * Applied double free patch from cras to Irssi SILC client.
1294 Affected files irssi/src/core/[modules/expandos].c
1296 * Fixed the disconnection handling to Irssi SILC Client.
1297 The application must call silc_client_close_connection
1298 in ops->connect client operation in case of failure of
1299 the connection. Affected file is
1300 irssi/src/silc/core/client_ops.c.
1302 * Do not set sock->protocol to NULL in the function
1303 silc_client_close_connection after executing the protocol's
1304 final callback since the sock might not be valid anymore.
1305 Affected file lib/silcclient/client.c.
1307 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Do not enable SILC_THREADS if the linking with libpthread
1310 did not happen. Affected file configure.in.pre.
1312 * Added notion to protocol specification that server must
1313 verify the sent authentication payload with CMODE when
1314 setting the channel founder key. Implemented it to the
1315 server. Affected file silcd/command.c.
1317 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Added _EXTRA_DIST SILC distribution variable to the
1320 distributions file. It is used to conditionally add extra
1321 files or directories to the specific distribution. Affected
1322 files ./prepare, Makefile.am.pre and distributions.
1324 Removed the `_' from the start of the distribution names.
1327 * Added README.WIN32 for instructions to compile the Toolkit
1330 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * Fixed a double free in disconnection in the server. Affected
1333 file is silcd/server.c.
1335 * Fixed the lib/silcske/groups.c to work now also with GMP
1336 MP library. The string conversion did not work when using
1337 specific base and the base is indicated in the string as well.
1339 * Created win32/ directory which now includes MSVC++ specific
1340 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1341 It will appear only in the toolkit distribution
1343 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Changed the key material distribution function in case when
1346 the hash output is too short. The data is now concatenated
1347 a bit differently than it used to. Made the change to the
1348 SKE protocol specification.
1350 * Added better GMP detection to configure.in.pre. A patch
1353 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1355 * Fixed a minor bug in SKE that might cause some problem on
1356 some platforms. Affected file lib/silcske/silcske.c.
1358 * Added the cookie checking for initiator in the SKE. It checks
1359 that the responder returns the sent cookie unmodified. The
1360 affected file is lib/silcske/silcske.c. Added new SKE
1361 error type INVALID_COOKIE that can be sent during the
1362 negotiation. Fixed some memory leaks as well.
1364 * Added the "invalid cookie" error message to Irssi SILC client's
1367 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Added `task_max' field to the SilcClientParams to indicate
1370 the maximum tasks the scheduler can handle. If set to zero,
1371 default values are used. Affected file lib/silcclient/silcapi.h.
1373 * Fixed memory leaks in silc_client_close_connection. Affected
1374 file lib/silcclient/client.c.
1376 * Added silc_client_del_client_entry to client library to free
1377 all memory of given client entry. Affected file is
1378 lib/silcclient/idlist.[ch].
1380 * Added new functions silc_client_del_channel and
1381 silc_client_del_server to delete channel and server entries.
1382 Affected file lib/silcclient/[silcapi.h/idlist.c].
1384 * Removed silc_client_del_client_by_id from silcapi.h.
1386 * Fixed the INFO command to return the server's own info
1387 correctly when querying by Server ID. Affected file is
1390 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Removed the non-blocking settings in WIN32 code in the
1393 silc_sock_[read/write] and added SleepEx instead. Affected
1394 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1395 of input data is now checked with FIONREAD and ioctlsocket.
1397 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Call silc_schedule_task_del_by_context in the
1400 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1401 Affected file lib/silccore/silcprotocol.c.
1403 * Call silc_protocol_cancel for active protocols in the
1404 silc_server_close_connection if the funtion
1405 silc_server_free_sock_user_data has not been called.
1406 Affected file silcd/server.c.
1408 * Generic tasks cannot be deleted using the del_by_fd
1409 task deleting function since generic tasks does not match
1410 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1412 * Added a notion to SILCOPER help file that the SILCOPER works
1413 only on router server, not on normal server.
1415 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Added for WIN32 support for the new scheduler as well.
1418 Affected file lib/silcutil/win32/silcwin32schedule.c.
1420 * Fixed the SHA1 implementation to work on various platforms.
1422 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1425 API. It is part of the scheduler now. Everything else is
1426 as previously but some functions has changed their names.
1427 Checkout the lib/silcutil/silcschedule.h for the interface.
1428 Updated all applications to use the new interface. Affected
1429 files are lib/silcutil/silcschedule.[ch].
1431 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Found a bug in the SKE implementation. The HASH value,
1434 specified by the protocol, was not computed correctly. The
1435 public key of the responder was not added to the computation
1436 even though it is mandatory. Affected file lib/silcske/silcske.c.
1437 This unfortunately causes incompatibilities with older
1438 clients and servers.
1440 * Added WIN32 specific network init and uninit functions:
1441 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1442 the Winsock2. Affected file lib/silcutil/silcnet.h and
1443 lib/silcutil/win32/silcwin32net.c.
1445 * Set the socket always to nonblocking mode on WIN32 after
1446 reading data or writing data. Affected file is
1447 lib/silcutil/win32/silcwin32sockconn.c.
1449 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Fixed various compilation problems under WIN32. Affected
1452 files lib/silcutil/win32/silcwin32thread.c and
1453 lib/silcutil/win32/silcwin32schedule.c.
1455 * Removed all _internal.h #includes from public header
1456 files. Internal headers must never be included from
1459 Removed also the lib/silcske/payload_internal.h file.
1461 * All include files that may be needed (public and some others
1462 included by the public headers) by application developers are
1463 now copied to the ./includes directory. It does not copy any
1464 internal headers. Affected file Makefile.defines.pre and all
1465 Makefile.am's under lib/ and subdirs.
1467 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Do not change the ~/.silc directory's permissions automatically.
1470 Affected file irssi/src/silc/core/clientutil.c.
1472 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Do not cancel the protocol in silc_server_close_connection
1475 it might cause recursion. Now cancelled in the function
1476 silc_server_free_sock_user_data. Affected file silcd/server.c.
1478 * Fixed the silc_server_remove_clients_by_server to regenerate
1479 the channel keys correctly finally. Added also new function
1480 silc_server_remove_clients_channels to actually do it.
1481 Affected file silcd/server.c.
1483 * Fixed the silc_server_new_channel to not crash by giving
1484 wrong router to the new channel. Affected file is
1485 silcd/packet_receive.c.
1487 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1490 which is given as argument to the silc_client_alloc now.
1491 It can be used to configure the client and set various parameters
1492 that affect the function of the client.
1494 * The USERS command in server did not check whether the channel
1495 is private or secret. Affected file silcd/command.c.
1497 * Added new argument to the USERS command in protocol specification.
1498 The USERS command now can take the channel name as argument
1499 as well. Added support for this in client and server and
1500 updated the protocol specs.
1502 * Completed the GETKEY command in client. It can be now used
1503 to fetch also servers public key not only some clients.
1504 Affected files lib/silcclient/command[_reply].c.
1506 * Added silc_client_get_server to return server entry by the
1507 server name. Affected files lib/silcclient/silcapi.h and
1510 * Redefined the IDENTIFY command in protocol specification to be
1511 more generic. It now can be used to query information about
1512 any entity in the SILC Network, including clients, servers and
1513 channels. The query may be based either the entity's name
1514 or the ID. Added support for this in both client and server.
1516 Affected files silcd/command.c and lib/silcclient/command.c
1517 and command_reply.c.
1519 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1520 the _from_client and _from_server functions. Affected file
1523 * Added silc_client_get_channel_by_id_resolve to the file
1524 lib/silcclient/silcapi.h to resolve channel information by
1525 its ID. Added also silc_client_get_channel_by_id that
1526 does not resolve it from the server.
1528 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Added SilcServerEntry context into the client library
1531 to represent one server. The INFO command now allocates
1532 these to save the resolved server info. For now on the
1533 client library will also keep information about servers,
1534 connected and resolved with INFO.
1536 The INFO command now allocates the SilcServerEntry context
1537 and saves the server info there. The COMMAND_REPLY in
1538 the INFO now returns the parameters to application in
1539 same order as defined in the protocol specification.
1541 The entries are cached in the client->server_cache.
1543 * The INFO command is now issued after received the Client ID
1544 from the server. Affected file lib/silcclient/client.c.
1546 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1547 to the application as the mode changer might be server.
1548 It is guaranteed that NULL is not returned anymore to the
1549 application. Affected file lib/silcclient/client_notify.c.
1551 The ID Type is now also passed to the application so that
1552 it can check whether the returned entry is SilcClientEntry
1555 Added new function silc_client_get_server_by_id to return
1556 the server entry by ID. Affected files are the
1557 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1559 * Do not create the channel in the Irssi SILC Client when issuing
1560 the JOIN command but when received the sucessful JOIN command
1561 reply. Otherwise the channel might get created even though we
1562 could not join it. The Affected file is
1563 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1565 * Fixed a channel joining bug in router. The router must also
1566 check the channel modes, invite and ban lists etc. when serving
1567 the JOIN command sent by normal server. Affected file is
1568 silcd/command.c. The router now resolves the client's
1569 information from the server who sent the JOIN command if it
1570 does not know it, and processes the JOIN command only after
1573 * Changed the SilcCommandCb to take new argument; void *context2.
1574 Affected file lib/silccore/silccommand.h
1576 The second argument in the command callbacks in the server now
1577 includes the SilcServerCommandReplyContext if the command was
1578 called as pending command callback from the command reply.
1579 Otherwise it is NULL. When called as pending the status of the
1580 command reply will be checked and if it was erronous the
1581 error will be sent to the original sender of the command.
1582 This way the client always receives the error messages even
1583 though the server was actually the one who received the error
1584 when it resent the command to router, for example. Affected
1585 files silcd/command[_reply].[ch].
1587 * Fixed sending WHOWAS command's error message to client if
1588 the requested client could not be found. It was missing.
1591 * Changed the CMODE and CUMODE commands reply arguments in the
1592 protocol specification. The Channel ID is now sent in both
1593 of the commands to identify the channel. Implemented this
1594 new feature to the client and server. Affected files
1595 lib/silcclient/command_reply.c and silcd/command.c.
1597 * Made better checks for invite and ban lists in the JOIN
1598 command in server. Affected file silcd/command.c.
1600 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * The server now performs the incoming host IP/DNS lookup
1603 using the silc_socket_host_lookup and thus does not block
1604 the server anymore. Affected file silcd/server.c.
1606 * Completed the multi-thread support for SILC Scheduler in
1607 the lib/silcutil/silcschedule.c.
1609 * Fixed the configure.in.pre to detect the pthread correctly
1612 * Fixed a deadlock in silc_task_queue_wakeup in the file
1613 lib/silcutil/silctask.c.
1615 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Added new function silc_schedule_wakeup that is used in
1618 multi-threaded environment to wakeup the main thread's
1619 schduler. It needs to be used when a thread adds a new task
1620 or removes a task from task queues. After waking up, the
1621 scheduler will detect the task queue changes. If threads
1622 support is not compiled in this function has no effect.
1623 Implemented the wakeup mechanism to both Unix and WIN32
1624 systems. Affected files are lib/silcutil/silcschedule.[ch],
1625 lib/silcutil/unix/silcunixschedule.c and the
1626 lib/silcutil/win32/silcwin32schedule.c.
1628 * Added new function silc_task_queue_wakeup to wakeup the
1629 scheduler by the specified task queue. Affected file
1630 lib/silcutil/silctask.[ch].
1632 * The silc_socket_host_lookup_start now wakes up the scheduler
1633 after adding the timeout task. Affected file is
1634 lib/silcutil/silcsockconn.c.
1636 * The silc_socket_host_lookup is synchronous now if the threads
1637 support is not compiled in. However, the callback is still
1638 called asyncronously through the scheduler, anyway. Affected
1639 file lib/silcutil/silcsockconn.c.
1641 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Added new function silc_socket_host_lookup to perform
1644 asynchronous IP and FQDN lookups for the socket connection.
1645 Affected files lib/silcutil/silcsockconn.[ch].
1647 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1650 that may or may not compile the mutex support in.
1652 Changed the silc_mutex_alloc interface. It allocates the
1653 mutex now to the sent pointer and returns TRUE or FALSE.
1655 Affected file lib/silcutil/silcmutex.h.
1657 * Wrote the SILC Task Queue interface to support multi-threads.
1658 Affected file lib/silcutil/silctask.[ch].
1660 * Wrote the SILC Scheduler to support multi-threads. Affected
1661 file lib/silcutil/silcschedule.c.
1663 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1666 in lib/silcutil/win32/.
1668 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Defined SILC Mutex API and SILC Thread API and implemented
1671 them for Unix. Affected files are
1672 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1673 lib/silcutil/unix/silcunixmutex.c and
1674 lib/silcutil/unix/silcunixthread.c.
1676 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed the silc_server_remove_clients_by_server's channel
1679 key re-generation. The hash table handling was incorrect
1680 and would not work with many channels. Affected file is
1683 * Fixed some memory leaks around the server code.
1685 * Rewrote the silc_server_get_users_on_channel to support IPv6
1686 based Client ID's. Affected file silcd/server.c.
1688 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1689 specification. However, a separate document must be written
1690 to define the detailed signing procedure and the payload
1691 associated with the flag. Defined the flag to the
1692 lib/silccore/silcchannel.h as well.
1694 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Changed the dynamic tables to static size tables in the
1697 lib/silccrypt/silchmac.c.
1699 * Removed GCC dependencies from the code. A patch by cras.
1701 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Do not show the error "Error receiving packet bla bla"
1704 in server if it really was not an error (-2 means that reading
1705 is pending). Affected file silcd/server.c.
1707 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Fixed a possible crash in silc_server_remove_clients_by_server
1710 in silcd/server.c. Fixed there also some memory leaks.
1712 * Fixed the silc_idlist_replace_client_id. It could replace
1713 wrong key in the hash table. Affected file silcd/idlist.c.
1715 * Do not check whether there are global users on the channel
1716 if the channel->global_users is FALSE. Affected functions
1717 silc_server_remove_from_one_channel and
1718 silc_server_remove_from_channels in silcd/server.c. Also,
1719 do not check if the removed client is local as we can be
1720 sure that global client was not removed from the channel
1721 and checking for global users is not needed.
1723 * The silc_server_remove_clients_by_server now re-generates
1724 the channel keys correctly for those channels that had
1725 clients removed from them. Affected file silcd/server.c.
1727 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Found the reason of random crashes in the server. We weren't
1730 ignoring the SIGPIPE signal (which can be sent in write())
1731 and it crashed the server. Affected file silcd/silcd.c.
1733 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Assure that sock->user_data is not NULL in the function
1736 silc_server_packet_send in silcd/packet_send.c.
1738 * Disconnect the remote connection if it could not be added
1739 to any ID lists in the server. The affected file is
1742 * Check in silc_server_packet_send[_real/dest] that the
1743 socket is not disconnecting and ignore the data if it is.
1744 Affected file silcd/packet_send.c.
1746 * Define inline to __inline on native WIN32 compilation.
1747 Affected file includes/silcwin32.h.
1749 * Added some explicit type casts for inline code since MSVC
1750 require them. Affected files lib/silcutil/silcbuffer.h,
1751 lib/trq/silcdlist.h and lib/trq/silclist.h.
1753 * Print warning in log files from now on if the packet
1754 decryption fails. Affected file silcd/server.c.
1756 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Changed the `say' client operation's interface to accept
1759 new `type' argument to indicate the type of the message sent
1760 by the library. The application may filter the library's
1761 messages according the type. The affected file is the
1762 lib/silcclient/silcapi.h.
1764 * Added two new functions to lib/silcclient/silcapi.h:
1765 silc_client_del_client and silc_client_del_client_by_id.
1766 Affected file lib/silcclient/idlist.c.
1768 * Moved the clientincludes.h from includes/ to silc/ and
1769 serverincludes.h from includes/ to silcd/.
1771 * The modes for the CMODE and CUMODE are now passed as
1772 uint32 for application with COMMAND_REPLY. The affected
1773 file is lib/silcclient/command_reply.c.
1775 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * /WHOIS without arguments shows client's own information.
1778 Affected file lib/silcclient/command.c.
1780 * Changed PING to not accept any arguments. The specs
1781 says that client can ping only the connected server so
1782 requiring an argument is not needed. Affected file is
1783 lib/silcclient/command.c.
1785 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1787 * Fixed a fatal bug in private message sending and reception
1788 encryption and decryption when using private message keys.
1789 The implementation was incorrect and did not follow the
1790 specification. It causd that some of the message were
1791 lost since it did not use the sending and receiving keys
1792 as the protocol suggests. This has been fixed and will cause
1793 incompatibilities with older clients when sending private
1794 message encrypted with private message keys. Affected files
1795 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1796 and various other in Irssi SILC Client.
1798 Added `responder' boolean argument to the functions
1799 silc_client_add_private_message_key[_ske] to indicate when
1800 the key is added as responder or initiator of the key
1803 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Removed the silc_ske_check_version function and created
1806 a SilcSKECheckVersion callback. Added also a function
1807 silc_ske_set_callbacks that is now used to set all SKE
1808 callbacks. The callback functions are not given to
1809 the SKE functions anymore, but this function is used to
1812 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1814 * Added `silc_version' argument to the silc_client_alloc
1815 to define the version of the application for the library.
1816 The library will use the version string to compare it
1817 against the remote host's (usually a server) version
1818 string. Affected file lib/silcclient/silcapi.h
1820 * Added the KE protocol context to Key Agreement context
1821 in client library so that we can abort the SKE if it
1822 is in process when we get timeout. Affected file is
1823 lib/silcclient/client_keyagr.c.
1825 * Do not resolve the client ID forever if it returns in the
1826 first time that such client does not exist. This was done
1827 for example with private message. Affected file is
1828 lib/silcclient/client_prvmsg.c.
1830 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Do not add regex.h for WIN32. The affected file
1833 includes/silcincludes.h.
1835 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1836 not work yet 100%. It generates the DLL's automatically
1837 when compiling with --with-win32 under cygwin.
1839 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * lib/contrib/regex.c is not compiled on WIN32.
1843 * Added silc_net_get_socket_opt function to the
1844 lib/silcutil/silcnet.h.
1846 * Added includes/silcwin32.h for WIN32 specific includes
1849 * Do not use ptime structure or any of the posix process
1850 functions on WIN32 in lib/silccrypt/silrng.c.
1852 * Added silc_gettimeofday to provide generic function
1853 for struct timeval on all platforms. Added the function
1854 to lib/silcutil/silcutil.h.
1856 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1859 library as they clearly belong there. As a plus side we
1860 can make the actual socket connection routines platform
1863 Added also new generic function silc_socket_read and
1864 silc_socket_write (that used to be silc_packet_[read/write].
1865 The implementation of these are platform specific.
1867 * Added WIN32 specific routines of silc_socket_[read/write]
1868 to lib/silcutil/win32/silcwin32sockconn.c.
1870 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Added preliminary support for native WIN32 compilation under
1873 cygwin (using the -mno-cygwin option for GCC) to the
1874 ./configure.in.pre. The --with-win32 now prepares the
1875 compilation for native WIN32.
1877 * Rewrote the SILC Scheduler interface in the file
1878 lib/silcutil/silcschedule.h. The scheduler is now context
1879 based and does not have anymore any global static scheduler.
1880 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1881 and created lib/silcutil/win32 directory for WIN32 based
1884 * Added Unix specific network routines to the
1885 lib/silcutil/unix/silcunixnet.c and the old
1886 lib/silcutil/silcnet.c includes now only generic routines.
1888 Added WIN32 specific network routines to the
1889 lib/silcutil/win32/silcwin32net.c.
1891 * Added Unix specific utility functions from the
1892 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1894 * Added WIN32 SILC Scheduler to the file
1895 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1898 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Do not handle JOIN notify in the server if the target client
1901 is not registered (idata->registered == FALSE). The affected
1902 file is silcd/packet_receive.c.
1904 * Update the nickrec->founder in event_cumode in the Irssi SILC
1905 client. Affected file irssi/src/silc/core/silc-channels.c.
1907 * Fixed the CUMODE_CHANGE notify handling in the server when
1908 server and router are announcing their clients on channels.
1909 Now the mode changes are saved and notified correctly. The
1910 affected file is /silcd/packet_receive.c.
1912 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1913 They really did not replace the cache entry in the ID Cache.
1914 Now they do that. Affected file silcd/idlist.c.
1916 * Fixed the KICK notify handling in the Irssi SILC client to
1917 update the channel records so that the kicked client does not
1918 appear to be on the channel. The affected file is
1919 irssi/src/silc/core/silc-channels.c.
1921 * Always update the conn->current_channel when executing command
1922 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1924 * Fixed the KILL notify handling in Irssi SILC client to remove
1925 the killed client on all channels.
1927 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Fixed the silc_parse_command_line to remove extra spaces
1930 from the start and end of the arguments. Affected file is
1931 lib/silcutil/silcutil.c.
1933 * Cancel and free any active protocol in the function
1934 silc_server_close_connection. Affected file silcd/server.c.
1936 * Cancel and free any active protocol in the function
1937 silc_client_close_connction. Affected file is
1938 lib/silcclient/client.c.
1940 * Do not execute the KILL command for clients that are in
1941 history (ie. they are not in the network). Affected file is
1944 * Fixed KILL notify handling, client does not crash anymore.
1945 Affected file irssi/src/silc/core/silc-channels.c.
1947 * Reduced the default packet buffer size from 2048 to 1024 in
1948 lib/silccore/silcpacket.c.
1950 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1951 counter to the SKE context that is incresed when the SKE library
1952 performs async operation outside the library. If the outside
1953 process frees the SKE context and FREED status will be set
1954 and the library will detect after the sync operation that the
1955 libary is freed. The affected files are
1956 lib/silcske/silcske[_status].[ch].
1958 * Resolve the client entry information in the function
1959 silc_client_channel_message to assure that NULL pointer is not
1960 passed as client entry to the application. */
1962 * Fixed the task timeout calculation to assure that there is
1963 never negative timeouts. The affected file is
1964 lib/silcutil/silcschedule.c.
1966 * Fixed the channel user mode notification sending in server.
1967 It was sent point-to-point to the router (or to server by router)
1968 but it needs to be destined to a channel. The routines now
1969 supports sending the channel user mode notifys to the channels
1970 when announcing clients and channels. Affected files are
1971 silcd/server.c and silcd/packet_receive.c.
1973 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1974 It did not actually replace the old channel entry in the cache.
1975 Affected file lib/silcclient/client_notify.c.
1977 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * Fixed a possible crash in silc_packet_send_prepare. It now
1980 assures always that there is enough space in the buffer and
1981 at the tail area of the buffer (for MAC).
1983 Fixed the inbound buffer reallocation in silc_packet_read.
1984 It was old code and did not handle the reallocation correctly.
1987 The affected file is lib/silccore/silcpacket.c.
1989 * Fixed buffer overflow in silc_parse_nickname in the file
1990 lib/silcutil/silcutil.c.
1992 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * make install generates new server keys only if there is not
1997 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2000 Added check that if the NOREPLY is set then we will not send
2001 the away message. This avoids infinite loop of away messages
2002 if both clients are away. The affected file is
2003 lib/silcclient/client_prvmsg.c.
2005 * Fixed client crash if /NICK was given without arguments.
2006 Affected file lib/silcclient/command.c.
2008 * Server does not send the invite list in INVITE command back
2009 to the client if the list was not altered. Added this notion
2010 to the protocol spec as well. Affected file silcd/command.c.
2012 Fixed possible crash in INVITE command by checking the
2013 value of silc_server_get_client_route command.
2015 * Fixed the INVITE notify type handling. The arguments are now
2016 taken in correct order and client does not crash. The affected
2017 file is irssi/src/silc/core/silc-channels.c.
2019 Removed the "Inviting xxx to channel" message from the
2020 client library away and let the application handle it.
2021 Affected file lib/silcclient/command.c. Added that message
2022 to Irssi SILC client's message formats.
2024 * Fixed CMODE command crash in client. It now checks the
2025 amount of arguments correctly and does not crash. The affected
2026 file is lib/silcclient/command.c.
2028 * Do not create new channel automatically in silc_channels_join
2029 but check whether the channel by that name already exists.
2030 Affected file irssi/silc/core/silc-channels.c.
2032 * Do not send the SERVER_SIGNOFF to router if the disconnected
2033 entity was the router. Affected file silcd/server.c.
2035 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2036 SILC client as it was missing from there.
2038 Added the handling of the KICK notify to the Irssi SILC client
2039 as it was missing. Added "you have been kicked" message to
2040 Irssi SILC client's message modules formats.
2042 Added the handing of the KILL notify to the Irssi SILC client
2043 as it was missing. Added the kill message module formats
2046 The affected file is irssi/src/silc/core/silc-channels.c.
2048 * The router did not save the channel mode the server announced.
2049 Affected file silcd/packet_receive.c.
2051 * Fixed a possible crash in INFO command in server. If the
2052 server did not provide the server info it crashed. Affected
2053 file silcd/command.c.
2055 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Fixed the GETKEY command in the server to check also the
2058 global list. Otherwise the GETKEY would not work correctly
2059 in normal SILC server. Affected file silcd/command.c.
2061 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Fixed GETKEY crash, it crashed if the command did not succseed.
2065 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2068 is now real and not just an macro interface to GMP.
2070 Removed the entire GMP from the source tree and imported new
2071 NSS MPI library instead. Reason for removing GMP is that it is
2072 extremely large and compiles extremely slow. The NSS MPI
2073 is only a few files and compiles in less than 10 seconds.
2074 The speed is also about the same as GMP. The MPI is imported
2075 to lib/silcmath/mpi.
2077 If the system has GMP installed we will still use the GMP.
2078 If it is not then the NSS MPI will be compiled.
2080 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2082 * Merged a long nickname (127 characters long) crash bugfix from
2083 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2085 * Merged a freed memory reference bugfix from Irssi CVS tree.
2086 Affected file irssi/src/core/commands.c.
2088 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added the server's public key sving and verification to the
2091 server when performing the SKE. This was missing and the
2092 remote server's (or router's) public key was accepted without
2093 checking whether we have it previously or trust it at all.
2094 Affected file silcd/protocol.c.
2096 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Check in the silc_server_timeout_remote if protocol is active
2099 and make sure that the protocol's final callback is called so
2100 that all memory if freed. Affected file silcd/server.c.
2102 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * silc_server_whois_send_reply crashed the server if the nickname
2105 was 127 characters long. Affected file silcd/command.c.
2107 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Added sanity check to the silc_server_new_client. If the hostname
2110 is provided inside username then check that the provided hostname
2111 really is the same as the resolved one. If the hostname was not
2112 resolved then check it from the public key. Affected file is
2113 silcd/packet_receive.c.
2115 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2116 if the server disconnected us and the connection is not valid
2117 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2119 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2120 the library to the lib/silcutil/silcutil.[ch].
2122 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Close log file after open. Affected file
2125 lib/silcutil/silclog.c.
2127 * Check whether sock == NULL in silc_client_send_packet and return
2128 if it is. Affected file lib/silcclient/silcclient.c.
2130 * Check rec->entry == NULL in the Irssi SILC Client before
2131 sending the channel message. Affecte file is
2132 irssi/src/silc/core/silc-servers.c.
2134 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Merged a splitted window bugfix from Irssi CVS tree. The
2137 affected file is irssi/src/fe-text/textbuffer-view.c.
2139 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2140 It did not print nickname.
2142 * Improved the distributions system a bit.
2144 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2147 irssi/src/fe-text/gui-window.c.
2149 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2150 to in-active server. The affected file is
2151 irssi/src/silc/core/client_ops.c.
2153 * Resolve the client in USERS command reply if the entry does
2154 not have username resolved. The affected file is
2155 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2156 command to WHOIS command to really resolve stuff. The USERS
2157 is not used any more in any critical section so WHOIS can
2158 be used even though it might be slower than IDENTIFY.
2160 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2163 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Changed the protocol API a bit more consistent in the
2166 lib/silccore/silcprotocol.[ch].
2168 * Changed the following headers to ROBODoc format:
2170 lib/silccore/silcpayload.h
2171 lib/silccore/silcprotocol.h
2172 lib/silccore/silcsockconn.h
2174 All core library headers are now formatted.
2176 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Fixed a bug in Irssi SILC client; do not show that you are
2179 server/router operator if you really are not. Affected file is
2180 irssi/src/silc/core/client_ops.c.
2182 * Renamed silc_command_free_payload to silc_command_payload_free.
2183 Affected file lib/silccore/silccommand.h
2185 * Added silcmath.h to include the prototoypes of various routines
2186 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2189 * Changed the following headers to ROBODoc format:
2191 lib/silccore/silcchannel.h
2192 lib/silccore/silccommand.h
2193 lib/silccore/silcid.h
2194 lib/silccore/silcidcache.h
2195 lib/silccore/silcmode.h
2196 lib/silccore/silcnotify.h
2197 lib/silccore/silcpacket.h
2198 lib/silcmath/silcmath.h
2200 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Added checking to the server code not to start the server if
2203 ciphers and stuff are not configured properly. Affected files
2204 silcd/serverconfig.[h] and silcd/server.c.
2206 * Changed the layout of the header files of the public interfaces
2207 in the SILC libraries. The new layout supports ROBODoc
2208 documentation tool (and some others) so that it is easy to create
2209 a library reference manual. All the other headers and source
2210 code must still follow the CodingStyle document. Also source
2211 code must not include these ROBODoc stuffs, only the headers.
2212 Furthermore, all public interface headers must now be named
2213 by using `silc' prefix, example: silcapi.h, silccipher.h.
2214 Some files were renamed due to this. All the other headers
2215 must not be used as public interfaces. I will update the
2216 CodingStyle document later. Changed following headers, so far:
2218 lib/silcclient/silcapi.h
2219 lib/silccore/silcauth.h
2220 lib/silccore/silcprivate.h
2221 lib/silccrypt/silcdh.h
2223 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Removed silc_client_packet_send_flush from the client library
2228 as it is not needed. Affected file lib/silcclient/client.[ch].
2230 * Added printing of message of unresolved authentication method
2231 to the Irssi SILC client. Added it to the module formats.
2232 Removed the same message from the client library.
2234 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Added new distribution feature, DISTLABEL. Every distribution
2237 can define own preprocessor label that can be used in the
2238 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2239 file distributions, acconfig.h.pre and prepare.
2241 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Added Makefile.defines_int to include the actual definitions
2244 for Makefile.defines.in. Tested the new distribution system,
2245 created distributions and tested installation.
2247 * Added AWAY message printing to the Irssi SILC client. Added
2248 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2250 * Added SCONNECT command to call the SILC's CONNECT command.
2251 Cannot use CONNECT directly since Irssi uses that internally.
2252 Affected file irssi/src/silc/core/silc-servers.c.
2254 Added ACTION local command. It is same as ME command but takes
2255 the channel as mandatory argument.
2257 Rewrote some of the Irssi's help files to suite for SILC
2260 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Added Makefile.defines[.in] that should for now on be included
2263 in all Makefile.am file in the source tree. That file includes
2264 all common compilation definitions for SILC source tree.
2266 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Minor changes to the ./prepare script to change the package
2269 name according the distribution name to the configure.in.
2271 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Created new distribution system. Added file `distributions'
2274 that defines all the distributions that can be created out of
2275 the SILC source tree. The ./prepare script now reads that
2276 file to determine how to prepare the distributions. The
2277 first argument to the ./prepare is the name of the distribution
2278 and second is the version of the distribution. If given
2279 without arguments it creates the default (toolkit) distribution
2280 with the default version (defined in ./prepare).
2282 All Makefile.am files that are subject to the distributions
2283 are now named as Makefile.am.pre. These are ./Makefile.am
2284 and lib/Makefile.am. Others may be changed later.
2286 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Added invite list, ban list, some key management and connection
2289 error message printing to module formats in the Irssi SILC client.
2291 * Added new silc_client_set_away_message to set the away message
2292 that is back to the person who sent private message. The
2293 affected file lib/silcclient/silcapi.h and the
2294 lib/silcclient/client_prvmsg.c.
2296 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Fixed the private message sending in the Irssi SILC client,
2299 added local command KEY to the Irssi SILC client.
2301 Added key management and key agreement message formats to the
2302 irssi/src/fe-common/silc/module-formats.[ch].
2304 Added USERS (alias WHO) printing, server/router operator
2305 indication and LIST command printing to the module formats.
2307 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Fixed channel joining notify handling, cumode notify handling
2310 from Irssi SILC client.
2312 * Added SILC specific module-formats to the Irssi SILC client so
2313 that SILC specific message hilighting, colors etc is possible.
2314 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2316 Added channel mode, channel user mode, actions, notices,
2317 whois and whowas printing to the the module-formats.c.
2319 * Fixed a bug in channel deletion in the server. The channel
2320 is not left to the cache even if the channel founder auth mode
2321 is set when there are no users anymore on the channel. Affected
2322 file silcd/server.c.
2324 * The silc_net_localhost now resolves the entire hostname including
2325 the domain name. Affected file lib/silcutil/silcnet.c.
2327 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2329 * Changed the ask_passphrase client operation to be ascynchronous.
2330 It has now a completion callback and a context that the
2331 application must call after it has got the passphrase from
2332 the user. Affected files lib/silcclient/silcapi.h,
2333 lib/silcclient/protocol.c, lib/silcclient/command.c and
2336 Added SilcAskPassphrase callback that the application calls
2337 to deliver the passphrase to the library.
2339 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2340 The public key verification and especially a certificate
2341 verification is asynchronous procedure.
2343 Added new SILC_SKE_STATUS_PENDING status to indicate the
2344 request is pending and a callback will be called to finalize
2347 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2348 indicate that remote end did not send its public key (or
2349 certificate), even though we require it. Added check for this
2350 condition in the SKE. This was a security bug, now fixed.
2352 Defined new SilcSKEVerifyCbCompletion callback that is called
2353 when the verification process is completed.
2355 The affected files lib/silcske/silcske_status.h and
2356 lib/silcske/silcske.[ch].
2358 * Changed the verify_public_key client operation to be async
2359 as well. Defined SilcVerifyPublicKey callback that is used to
2360 indicate the success of the public key verification process.
2362 Changed the server and client to use the new async client
2365 * Changed the Irssi SILC client's internal scheduler to be called
2366 twice as many times as it used to be. As a result the client
2367 should be a bit faster now. Affected file is
2368 irssi/src/silc/core/silc-core.c.
2370 * Added support to Irssi SILC client of asynchronous public key
2371 verification and passphrase inquiry. Affected file is
2372 irssi/src/silc/core/silc-core.c.
2374 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Do not say "You have left channel %s" in client library.
2377 Moved it to the application. Affected files are
2378 lib/silcclient/command.c and silc/client_ops.c.
2380 * Fixed silc_client_get_clients. Command context was not
2381 duplicated and was freed memory in the callback. Affected
2382 file lib/silcclient/idlist.c.
2384 * Do not say "you are now talking..." on JOIN command in the
2385 client library. The appliation must handle it.
2387 * Do not say ".. changed topic to" in command reply in the
2388 client libary. The application must handle it.
2390 * Fixed TOPIC command sending in the client library.
2392 * Fixed a memory leak in silc_client_command_free in the file
2393 lib/silcclient/command.c.
2395 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Imported a modified version of Irssi client to the source tree.
2398 The Irssi will be used to create a new client called
2399 Irssi SILC. Imported to irssi/.
2401 Added silc_core_init_finish function to the Irssi. Affected
2402 file irssi/configure.in.
2404 A lot changes in the Makefile.ams around the irssi tree.
2406 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Do not rehash if the new size is same as the old size of the
2409 hash table, in the silc_hash_table_rehash*. The affected file
2410 lib/silcutil/silchashtable.c.
2412 * Replaced hash_table_del_by_context calls from the server
2413 (when channel->user_list and client->channels) to the
2414 hash_table_del as it is sufficient and faster.
2416 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Added silc_hash_table_list, silc_hash_table_get and the
2419 SilcHashTableList structure to provide an alternative way to
2420 traverse the hash table. The affected files are
2421 lib/silcutil/silchashtable.[ch].
2423 * Changed the server's idlist routines to use the hash table
2424 routines to optimize the code.
2426 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Replaced the client entry's `channel' list and channel entry's
2429 `user_list' list to hash tables for optimized lookup. Changed
2430 the code to use the hash table interface around the code.
2431 Affected file lib/silcd/idlist.[ch].
2433 * Added `auto_rehash' boolean argument to the function
2434 silc_hash_table_alloc to indicate whether the hash table should
2435 auto-rehash when it thinks is appropriate time. It will
2436 increase the hash table size if the there is twice as much
2437 entries in the table than the size of the table, and will
2438 decrease the size if there are twice as less entries than
2439 the size of the table.
2441 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2445 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * silc_idcache_purge_by_context deletes the entry now by context
2448 as it is supposed to do. Affected file lib/silccore/idcache.c.
2450 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2451 client is not anymore valid (WHOWAS givens the info) and not
2452 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2454 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Removed the `data' and `data_len' arguments from the ID Cache
2457 interfaces and added `name' argument. ID Cache does not handle
2458 anymore the binary data only a names associated with given ID.
2460 * When hashing a Client ID with silc_hash_id the entire ID is
2461 not hashed anymore, instead only the hash of the Client ID is
2462 hashed. This way we can access the Client ID from the cache
2463 with Client ID but with the hash of the ID (which is a hash of
2464 the nickname) as well without any difference in performance.
2466 Added also silc_idcache_find_by_id_one_ext to do one on one
2467 searching when we have the actual ID. Added also function
2468 silc_hash_client_id_compare. The affected files are
2469 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2471 * When hashing the name associated with a ID it is always done
2472 in lowercase. This way we can access the cache without worrying
2473 about case-sensitivity, even though, for example nicknames are
2476 * Fixed a bug in server with channel message sending. It put
2477 wrong ID type as destination ID. The affected file
2478 silcd/packet_send.c.
2480 * silc_idcache_del_by_context now deletes from all hash tables
2481 by context. Affected file lib/silccore/idcache.c.
2483 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Changed the client library to use the new ID Cache interface.
2486 Changes around the source tree.
2488 * Added silc_hash_table_rehash_ext to rehash with specific
2489 hash function. Affected file lib/silcutil/silchashtable.[ch].
2491 * Added silc_hash_string_compare to compare two strings in the
2492 hash table. Affected file lib/silcutil/silcutil.[ch].
2494 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Added new function silc_idcache_del_by_context into the
2497 lib/silccore/idcache.[ch].
2499 * Changed the server's ID list routines to use the new ID Cache
2500 interface. Changes around the source tree.
2502 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Added silc_hash_table_del[_by_context]_ext functions in to the
2505 lib/silcutil/silchashtable.[ch].
2507 Removed silc_hash_table_find_all* routines and added new
2508 silc_hash_table_find_foreach to replace them.
2510 Added silc_hash_table_replace_ext function as extended
2511 replacing function. Separated the simple hash table interface
2512 from the extended hash table interface in the file
2513 lib/silcutil/silchashtable.h.
2515 * Fixed minor bugs and changed it to use some of the new
2516 hash table functions in lib/silccore/idcache.c
2518 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Added new function silc_hash_table_find_all to return all keys
2521 in the hash table by the specified key. As the hash table is
2522 collision resistant it also makes it possible to have several
2523 duplicate keys in the hash table. This function may be used to
2524 find all of the keys from the hash.
2526 Added user_context arguments to the SilcHashFunction,
2527 SilcHashCompare and SilcHashDestructor to deliver user specified
2530 Added new fuctions silc_hash_table_find[_all]_ext to do
2531 extended lookup with specified hash and compare functions and
2532 specified user contexts.
2534 Added new function silc_hash_table_add_ext to add the key
2535 with specified hash function and user context.
2537 Added new function silc_hash_table_foreach to traverse all
2538 entrys in the hash table. Added SilcHashForeach callback
2541 Added new function silc_hash_table_del_by_context to delete
2542 the entry only if the context associated with the key matches.
2544 Affected files are lib/silcutil/silchashtable.[ch].
2546 * Removed silc_hash_[server/client/channel]_id and added just
2547 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2548 silc_hash_id_compare to compare two ID's using as the hash table
2549 comparison function. Added also silc_hash_data to hash
2550 binary data and silc_hash_data_compare to compare it.
2552 * Removed silc_idlist_find_client_by_hash as it is not needed
2553 anymore. Affected file silcd/idlist.[ch].
2555 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2556 to use internally the SilcHashTable. The new ID Cache is a lot
2557 faster than the old one. Some of the ID Cache interface was also
2558 rewritten and obsolete and stupid functions were removed.
2560 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Added entry_count field to the SilcHashTable to keep the number
2563 of the entries in the table. Implemented the function
2564 silc_hash_table_rehash. Added new function
2565 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2567 Fixed a minor bug in silc_hash_table_free.
2569 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2570 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2571 into the lib/silcutil/silcutil.[ch].
2573 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Implemented a collision resistant hash table into the
2576 lib/silcutil/silchashtable[ch]. See the header and the source
2577 for the SilcHashTable API.
2579 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Merged dotconf version 1.0.2 into lib/dotconf.
2583 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Do not compile anything in lib/silcsim/* if the SIM support
2586 is not enabled. The tree should now compile without problems
2589 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Compiled the SILC under cygwin. Compiled and tested briefly
2592 without problems. More tests needed. The SIMs didn't compile
2595 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2597 * Fixed possible crash in silc_get_username in the
2598 lib/silcutil/silcutil.c.
2600 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Fixed a va_arg in silc/client_ops.c.
2604 * Oops, RC5 routines were named AES and caused some problems
2605 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2607 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Added new SilcIDIP structure into the lib/silccore/id.h and
2610 replaced the old `ip' fields from all SILC ID's to that type.
2611 This is a step towards IPv6 support.
2613 The silc_id_get_len takes now the ID as an extra argument.
2614 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2615 both IPv4 and IPv6 based ID's.
2617 The affected files are lib/silccore/id.[ch] and other files
2618 around the tree using these routines.
2620 * Removed the ID length arguments in server from various
2621 silc_server_send_notify_* routines -> they are not needed
2624 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Fixed memory leak in silc_encode_pem_file in the file
2627 lib/silcutil/silcutil.c.
2629 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Check minor version as well in the SKE. Affected files are
2632 silcd/protocol.c and lib/silcclient/protocol.c.
2634 * Added --identifier option to the server so that an identifier
2635 can be when creating the public key for the server. Affected
2636 file is silcd/silcd.c.
2638 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2639 lib/silccrypt/silcpkcs.c.
2641 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Register default ciphers and stuff when using -C option with
2644 the server. Affected file sildc/silcd.c.
2646 * Put back the servers public key filename format, it is better
2647 than the new one. For now, the client keys are saved with the
2648 new filename format. The affected file silc/client_ops.c.
2650 * Implemented the Cipher API for the rest of the ciphers that
2651 did not implement it or implemented it the wrong way.
2653 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Register default ciphers and stuff when using the -S option
2656 in the client. Affected file silc/silc.c. Same also when
2657 creating new key pair with -C option.
2659 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Fixed the silc_verify_public_key client operation function to
2662 save the public keys differently. The fingerprint is now
2663 used as filename and not the hostname. This way also the
2664 client keys are saved uniquely and not with hostnames. The
2665 affected file is silc/client_ops.c.
2667 * Trimmed the silc_hash_fingerprint function to remove extra
2668 whitespaces from the end of the fingerprint. The affected
2669 file is lib/silccrypt/silchash.c.
2673 * Added silc_cipher_register_default function to register all
2674 default ciphers. It can be used when configuration files
2675 does not exist and the application does not want any specific
2676 ciphers in any specific order.
2678 The SilcDList is now used as silc_cipher_list dynamically
2679 allocated cipher list. Removed the static list all together
2680 and now all ciphers must be allocated to the dynamic list.
2681 The silc_cipher_alloc routine was changed to check only the
2684 All silc_cipher_* routines that used to return int returns
2687 The affected files lib/silccrypt/silccrypt.[ch].
2689 * The same thing was done to silc_hash_* as for silc_cipher_*
2690 routines. Affected files lib/silccrypt/silchash.[ch].
2692 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2693 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2694 Added also silc_pkcs_[un]register[_default] functions.
2695 Removed the data_context from the PKCS API.
2697 * Added silc_hmac_register_default function to register default
2698 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2699 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2700 to unregister all hmacs at once.
2702 * Register the default ciphers, hash functions, PKCSs and HMACs
2703 if client's configuration file does not exist. The affected
2706 * The client did not load the hash functions from the SIM
2707 modules at all. Added support for this. Affected file is
2708 silc/clientconfig.c.
2710 * When decoding public key with silc_pkcs_public_key_decode, check
2711 the supported algorithm only if PKCS are registered. Affected
2712 file lib/silccrypt/silcpkcs.c. The same was done with the
2713 silc_pkcs_private_key_decode.
2715 * Fixed the SILC List routines to keep the list always in order.
2716 It used to change the list's order when traversing the list but
2717 not it preserves the order. Affected file lib/trq/silclist.h.
2719 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Added the client library to use the SilcSocketConnection's
2722 reference counter (by silc_socket_dup) to prevent the bug that
2723 the socket object may be freed underneath async operation.
2725 * The name resolv library checking fixes in the configure.in.pre.
2728 * Created new version of the protocol drafts for future
2729 development. The -03 drafts are the ones that will be changed
2730 in the trunk now and the -02 will remain as they are.
2732 * Send list of CUMODE notifys to the router when announcing
2733 the channel users to the router. Affected file silcd/server.c.
2734 If the router receiving channel founder CUMODE for a channel
2735 that already has channel founder it will send CUMODE notify
2736 to the sender to remove the channel founder rights from the
2737 announced client. Affected file silcd/packet_receive.c.
2739 * The CUMODE notify may now use Server ID as well as the entity
2740 who changes the mode. Updated protocool specs.
2742 * Updated INSTALL and README files.
2744 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * New web pages in the http://silc.pspt.fi. The pages was
2751 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Implemented the [DenyConnectin] config section in the server.
2754 Added silc_server_config_denied_conn to check whether incoming
2755 connection is denied. Affected file silcd/serverconfig.[ch].
2757 * Do not check the ports when checking the incoming configuration
2758 data if the port is 0, meaning any. Affected file is
2759 silcd/serverconfig.c.
2761 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Fixed buffer overflow in silc_string_compare in the file
2764 lib/silcutil/silcutil.c.
2766 * Fixed double free in silc_server_command_leave in the file
2769 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Fixed the version checking in the server. Affected file is
2774 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2776 * Fixed the configuration data fetching when accepting new
2777 connections in the server. Affected file silcd/server.c.
2779 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Added `sender_entry' argument to the function
2782 silc_server_packet_relay_to_channel so that we can check
2783 whether some destination actually belongs to the same route
2784 the sender belongs (ie, we must not resend the packet to the
2785 sender). Affected file silcd/packet_send.[ch].
2787 * Added `servername' field to the SilcClientEntry in the server
2788 to hold the name of the server where client is from. Affected
2789 file is silcd/idlist.h.
2791 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Moved the channel message encrypting in the router betwen
2794 router connections from silc_server_channel_message to the
2795 silc_server_packet_relay_to_channel since we want to check
2796 whether we have anybody channel before encrypting anything.
2797 Affected files silcd/packet_[receive/send].c.
2799 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Fixed the [AdminConnection] server config section to support
2802 multiple entries. Affected file silcd/serverconfig.c.
2804 * Added support into the server to check the validity of the
2805 incoming connection before executing any KE or authentication
2808 * The connection configuration is now saved to the KE and
2809 connection auth protocol contexts and not fetched anymore in
2810 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2812 * The local hosts listenning address and port is also resolved
2813 now when starting the server. We want to have the socket object
2814 to include the real address and port for the listener. Added
2815 new function silc_net_check_local_by_sock into the files
2816 lib/silcutil/silcnet.[ch].
2818 * Fixed a broadcast bug in server -> do not broadcast if we
2821 * Fixed a routing bug. Do not route broadcast packets ever.
2822 Broadcast packets must be processed always and not routed since
2823 they may be destined to some other host than yourself and thus
2824 would get routed without no good reason. Affected file is
2827 * Added function silc_server_config_is_primary_route to check
2828 whether primary router connection has been configured (a router
2829 configuration that we are initiating). If there is not, we
2830 will assume that there is only two routers in the SILC network
2831 and we will use the incoming router connection as our primary
2832 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2834 * Changed the order of the broadcasting. Broadcast _after_ the
2835 packet has been processed not before. Affected file is
2838 * Fixed a [ClientConnection] parsing bug. The port was never
2839 parsed correctly thus resulting to port 0. Affected file
2840 silcd/serverconfig.c.
2842 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2843 argument and did not set the broadcast packet flag. Affected
2844 file silcd/packet_send.c. Fixed same bug in the function
2845 silc_server_send_notify as well.
2847 * If we receive NEW_ID packet for our own ID in the server, ignore
2850 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Removed the nickname from the Private Message Payload.
2855 Updated the code and the protocol specs.
2857 * Updated protocol specs for submitting to the IETF.
2859 * Tweaked the Random Number Generator a bit. Affected file
2860 lib/silccrypt/silcrng.c. Exported a new function
2861 silc_rng_[global]_add_noise which can be used to add more
2864 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Do not parse packets with different timeout when protocol
2867 is active -> may cause problem with rekey. Affected file
2870 * When server receives signoff notify it must not create
2871 new channel key if the client is on any channels since the
2872 sender of the signoff notify will create it.
2874 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Added printing of error messages during SKE protocol from the
2877 failure packet sent by server during SKE. Affected file
2880 * Removed the client's failure_callback handling with timeout
2881 and handle it immediately when received.
2883 * The SKE library returned wrong type in SUCCESS and FAILURE
2884 packets. They must be 32 bit MSB not 16 bit MSB.
2886 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Ok, rewrote the logic of the re-key and now it seems to work.
2889 I tested it on high traffic with frequent re-keys without
2890 problems. Added hmac_receive (and renamed hmac to hmac_send)
2891 in SilcClientConnection in lib/silcclient/client.h and
2892 in SilcIDListData in silcd/idlist.h. Also, removed the
2893 SilcPacketParserContext's cipher and hmac fields as they are
2894 not needed anymore and actually caused some problems when
2895 the ciphers and hmac's changed underneath the packet parser.
2897 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * If re-key protocol is active then process the incoming packets
2900 synchronously since we must assure that icoming packets encrypted
2901 with the old key is processed before the new keys is set to
2902 use. This is true other packets than for REKEY packets.
2903 Affected file silcd/server.c. The same was done to client library
2904 as well, affected file lib/silcclient/client.c.
2906 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Fixed bug in client and server to accept the force send if
2909 the packet is send from silc_[server/client]_packet_process
2910 function. Otherwise the packets are never delivered, oops.
2912 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Disable force sending of packets when REKEY protocol is active.
2915 We must assure that no packet is sent directly when rekey is
2916 performed. All packets must be sent through packet queue.
2917 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2918 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2919 function is silc_[server/client]_packet_send_real to check
2922 * Replaced the SIM paths from example config files to
2923 /usr/local/modules. Also, make install creates now
2924 /usr/local/silc/logs directory to hold all the SILC server
2927 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Made the configure.in.pre work on Solaris. Patch by salo.
2931 * Made all ciphers compatible with non-x86 machines. Defined
2932 CBC mode macros into lib/silccrypt/ciphers_def.h.
2934 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Fixed the make install.
2938 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * When MAC computation fails the silc_packet_decrypt returned 0
2941 even though it was supposed to return -1. Fixed this. The
2942 affected file is lib/silccore/silcpacket.c.
2944 * Do not replace the config files in /etc/silc (in make install)
2945 if they already exist. Affected file ./Makefile.am.
2947 * Do not send re-key packets immediately but through packet queue.
2948 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2950 * Changed silc_net_check_host_by_sock to return FALSE if the
2951 IP/DNS could not be resolved. Though, it returns the IP address
2952 now even if it could not resolve it (but returns also FALSE).
2953 Affected file lib/silcutil/silcnet.[ch].
2955 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added silc_pkcs_decode_identifier to decode the public key's
2958 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2959 Added also silc_pkcs_free_identifier. Added also new context
2960 SilcPublicKeyIdentifier.
2962 * Added -S option to the silc client. It is used to dump the
2963 contents of the specified public key file.
2965 * Changed the PKCS api to return the public key length when
2966 setting the public key.
2968 * Fixed a fatal bug in the public and private key file loading.
2969 Affected file lib/silccrypt/silcpkcs.c.
2971 * Execute the packet parsing for client with zero (0) timeout
2972 if the protocol is active. Affected file silcd/server.c.
2974 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Made the key generation options to the silcd program. Added
2977 -C option, equivalent to client's option.
2979 * Added new [ServerKeys] config section to the server. It
2980 configures the server's public and private key.
2982 * Defined generic Public Key Payload into the protocol
2983 specification to send specific type of public keys and
2986 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2987 public key or certificate.
2989 * Implemented the GETKEY command to the server and to the
2990 client library and on user interface.
2992 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Made preliminary `make install' work.
2996 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added SilcServerRekey context into silcd/idlist.h.
3000 * Added the PFS support as defined in the specification to the
3001 SKE protocol. Affected files lib/silcske/*.c.
3003 * Added `ske_group' field to the SilcServerRekey context to hold
3004 the number of the SKE group that is used with PFS in re-key.
3005 Affected file silcd/idlist.h.
3007 * Added PFS re-key support to the server. Affected file is
3010 * Added silc_protocol_cancel to cancel execution of the next
3011 state of the protocol. Affected file is
3012 lib/silccore/silcprotocol.[ch].
3014 * Added the re-key support with and without PFS to the client
3015 library. Re-key is performed once in an hour, by default.
3017 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3018 Added silc_client_rekey_callback and silc_client_rekey_final.
3019 Affected files are lib/silcclient/protocol.[ch] and
3020 lib/silcclient/client.[ch].
3022 * Removed the `hmac_key' and `hmac_key_len' fields from the
3023 SilcClientConnection structure; not needed. Affected file is
3024 lib/silcclient/client.h.
3028 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Do not ask whether user wants to use the negotiated private key
3031 for private messages, just use it. Affected file is
3032 silc/local_command.c.
3034 * Added `send_enc_key' and `enc_key_len' fields to the
3035 SilcIDListData structure since they are needed in the re-key
3036 phase. Affected file is silcd/idlist.[ch].
3038 * Implemented the simple re-key protocol into the server.
3039 Affected files silcd/server.c and silcd/protocol.[ch]. The
3040 re-key will be performed once in an hour, by default.
3042 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3043 Added silc_server_rekey, silc_server_rekey_callback and
3044 silc_server_rekey_final.
3046 * Removed Tunneled flag from the protocol. Updated the code
3047 and the specifications.
3049 * Adde `pfs' field to the SilcIDListData to indicate whether
3050 the PFS is to be performed in the re-key. Affected file is
3053 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3056 int64 of at least the xintXX size. If void * is less that 4
3057 bytes uint32 * will be used. Defined bool as boolean.
3059 * Changed _ALL_ unsigned long and unsigned int to uint32,
3060 unsgined short to uint16 in the source tree.
3062 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3063 not handle clients that has entry->data.registered == FALSE.
3064 They are not in the network anymore. Affected file is
3067 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Implemented the sending of the SERVER_SIGNOFF notify in the
3070 server. Affected file is silcd/server.c.
3072 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3073 Added also silc_notify_payload_encode_args into the
3074 lib/silccore/silcnotify.[ch].
3076 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3077 Affected file silcd/packet_receive.c.
3079 * Implemented the SERVER_SIGNOFF notify handling in the client
3080 library. Affected file lib/silcclient/client_notify.c. Also,
3081 implemnted the printing of the SERVER_SIGNOFF info to the
3082 application. Affected file silc/client_ops.c.
3084 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3085 if the deleting was successful. Affected file silcd/idlist.[ch].
3087 * Added support for public key authentication in the connection
3088 authentication protocol in the client library. Affected file
3089 lib/silcclient/protocol.c.
3091 * Changed the server's silc_idlist_get_clients_by_* interface
3092 to support already allocated array so that new entries may be
3093 added to pre-allocated array. Affected file silcd/idlist.[ch].
3094 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3095 and command replies.
3097 * All command reply functions in the server now calls the
3098 pending command callback even if error occured. This way the
3099 error will be delivered to the client as well. Affected files
3100 silcd/command.c and silcd/command_reply.c.
3102 * Fixed INFO command to return local server's info if no server
3103 was provided. Affected file lib/silcclient/command.c.
3105 * Removed RESTART command for good. Updated the code and the
3108 * Rewrote parts of the task system. It is a bit simpler now.
3109 Removed unsued task priorities. The affected files are
3110 lib/silcutil/silctask.[ch].
3112 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Moved the USERS printing from the library to the application.
3115 Affected files lib/silcclient/command.c and silc/client_ops.c.
3117 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Added channel key re-key support. The re-key is perfomed
3122 only by the router and is done once in an hour. Added `rekey'
3123 field to the SilcChannelEntry in the server. Affected files
3124 silcd/server.c and silcd/idlist.h.
3126 * Added silc_task_unregister_by_context into the file
3127 lib/silcutil/silctask.[ch].
3129 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Added SILC_UMODE_GONE mode to indicate when the client is not
3132 present in the SILC network. Added also support to the local
3133 command AWAY that will set this mode. Added support of showing
3134 "xxx is gone" in WHOIS command. The USERS command shows the
3135 gone status as well.
3137 * Fixed setting server and router operator privileges in the
3138 server's UMODE command. Affected file silcd/command.c.
3140 * Merged the SKE KE1 and KE2 payloads into one payload. The
3141 new KE payload is equivalent to the old KE2 payload.
3143 Cleaned up the SKE Start Payload parsing. It now uses the
3144 simple buffer unformatting to do the parsing. A lot faster
3147 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3148 to the SKE that is used to indicate whether both of the SKE
3149 parties should perform authentication. By default only the
3150 responder performs authentication. By setting this flag also
3151 the initiator must do authentication. By default it is unset
3152 since in normal SKE case, client to server connection, only
3153 the responder should do authentication. When doing SKE between
3154 two clients both should perform authentication. Updated the
3155 code and the protocol specs.
3157 * A little fix to IDENTIFY command in the server. Search the
3158 client first by hash not nickname. Affected file is
3161 * Fixed the silc_client_close_connection to support closing
3162 the client to client connections wihtout deleting too much
3163 data. Affected file lib/silcclient/client.c.
3165 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3166 are received if protocol used to be active but is not anymore
3167 the application would crash due to NULL pointer dereference.
3168 Affected files silcd/server.c and lib/silcclient/client.c.
3170 * Added `hash' field to the SilcClientConnection to include
3171 the hash function negotiated in the SKE protocol.
3173 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3174 to set the channel founder authentication data. A client can
3175 claim the founder rights later by providing the authentication
3176 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3177 This way the channel founder can regain the channel founder
3178 privileges even it is left the channel. This works only on
3179 local server and the client must be connected to the same
3180 server to be able to regain the founder rights. Updated the
3181 protocol specs accordingly.
3183 Added support to the CMODE command in the client to set the
3184 founder auth data. Read the README to see how to set it.
3186 Added support to the CUMODE command to claim the founder
3187 rights. Read the README to see how to do it.
3189 Added support for the founder authentication to the Channel
3190 Entry in the server. Affected file silcd/idlist.h.
3192 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3193 server's CMODE command. Affected file silcd/command.c.
3195 * Added the following new functions into lib/silccore/silcauth.[ch]:
3196 silc_auth_get_method and silc_auth_get_data.
3198 * The server now saves the remote hosts public key to the
3199 SilcIDListData pointer. Affected file silcd/protocol.c.
3201 * The normal server now does not remove the channel entry from
3202 the cache if the founder authentication data is set. It used
3203 to remove it if the founder was the last one on the channel on
3204 the server and left the channel. The auth data is saved and
3205 if the channel is re-joined later the old entry is used with
3206 the old auth data. Affected files silcd/command_reply.c and
3209 * Removed the `pkcs' field from the SilcIDListData structure
3210 in the server; it is not used. Affected file silcd/idlist.h.
3212 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Fixed packet processing on slow links. Partial packets were
3215 never re-processed because the incoming data buffer was cleared
3216 by the application. Application must not directly clear the
3217 sock->inbuf, the packet processing routines handle it. Fixed
3218 this in client library and in server.
3220 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Fixed the WHOIS and IDENTIFY send reply function to really
3223 check whether to send list or just one entry. Affected file
3226 * Cleaned up the LEAVE command's channel key distribution. The
3227 affected file silcd/command.c.
3229 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3230 can enforce the channel mode as well. In that case the ID
3231 includes the ID of the server. The code now enforces the
3232 mode change if the router have different mode than the server.
3234 * The notify client operation with CMODE_CHANGE notify can now
3235 return NULL client_entry pointer if the CMODE was not changed
3236 by client. Application must check for this.
3238 * Added <Server ID> argument to INFO command to support server
3239 info fetching by Server ID.
3241 * Added silc_server_announce_get_channel_users to get assembled
3242 packets of channel users of the specified channel. Affected
3243 file silcd/server.[ch].
3245 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3246 was freed underneath the ID Cache.
3248 * Re-announce clients when the server received CHANNEL_CHANGE
3249 notify from the router. Affected file silcd/packet_send.c.
3251 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3254 crashed since it did not handle the fact that there is no cipher
3255 called "3" and didn't check the error condition. Now fixed.
3257 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3258 flag. It can be used to send message requests.
3260 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Implemented the RESTART command in the client.
3264 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3265 notice type messages. Added notice printing to the user
3268 * The channel keys are not re-generated if the channel's mode
3269 is PRIVKEY, ie private key on the channel exists. Affected
3270 files silcd/server.c and silcd/command.c.
3272 * Fixed a little bug in channel message delivery when channel
3273 private keys are set in the server. Affected file is
3274 silcd/packet_send.c.
3276 * Changed the setting on channel->on_channel = TRUE from the
3277 silc_client_save_channel_key to the JOIN command reply. The
3278 key payload is not received if the private channel key is set.
3279 Affected file lib/silcclient/command_reply.c and the
3280 lib/silcclient/client_channel.c.
3282 * When the CMODE_CHANGE notify is sent and the channel private
3283 key mode is removed the channel key must be re-generated in
3284 other cells as well. Added this support for the router in the
3285 silcd/packet_receive.c.
3287 * Added new local command NOTICE to send notice message on
3288 channel. Affected file silc/local_command.[ch].
3290 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added new local command ME to the client. It is used to send
3293 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3294 some action. Affected file silc/local_command.[ch].
3296 * Changed channel_message and private_message client operations
3297 to deliver the message flags to the application. Added also
3298 the `flags' arguments to the silc_client_send_channel_message
3299 and silc_client_send_private_message functions. Affected file
3302 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Redefined the Private Message Payload to support private message
3305 keys and to support the new private message flags. Updated
3306 the protocol specs. Flags makes it possible to have for example
3307 CTCP style messages.
3309 * Added new type SilcPrivateMessagePayload and defined an API
3310 for it in the lib/silcclient/silcprivate.[ch].
3312 * Tested private message private keys successfully. Tested the
3313 private message key set, unset and list commands with the new
3316 * Redefined the Channel Message Payload to include the channel
3317 message flags (equal with private message flags) to support
3318 for example CTCP style messages.
3320 * Defined some of the message (for channel and private message)
3321 flags. Updated the protocol specs and added the flags to the
3322 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3324 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Added SilcKeyAgreementStatus type to the key agreement routines
3327 to indicate the current status and error if one occured.
3328 The status types are defined in the lib/silcclient/silcapi.h.
3330 * Added new local command KEY that is used to set and unset private
3331 keys for channels, set and unset private keys for private messages
3332 with remote clients and to send key agreement requests and
3333 negotiate the key agreement protocol with remote client. The
3334 key agreement is supported only to negotiate private message keys,
3335 it currently cannot be used to negotiate private keys for channels,
3336 as it is not convenient for that purpose.
3338 * Fixed a minor pending callback setting bug in the function
3339 silc_client_get_client_by_id_resolve, now the function works.
3340 Affected file lib/silcclient/idlist.c.
3342 * Added function silc_net_get_local_port to get local bound
3343 port by socket. Added to lib/silcutil/silcnet.[ch].
3345 * Added `sockets' and `sockets_count' fields to the SilcClient
3346 object. They hold the sockets of the listenning sockets in
3347 the client. Listenning sockets may be for example the key
3348 agreement server. Affected file lib/silcclient/client.[ch].
3349 Added functions the silc_client_add_socket and the
3350 silc_client_del_socket. They are exported to the application
3353 * Added ~./silc/clientkeys to support other client's public keys.
3355 * Renamed verify_server_key client operation to verify_public_key
3356 and added one argument to indicate the type of the connection
3357 (server, client etc.).
3359 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Added silc_server_connection_auth_request to handle the
3362 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3363 silcd/packet_receive.[ch].
3365 * Added silc_server_send_connection_auth_request into the
3366 silcd/packet_send.c to send the connection auth request packet.
3368 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3371 * Fixed the public key authentication in responder side in the
3372 server. The `auth_data' pointer includes the SilcPublicKey
3373 not the path to the public key. Affected file silcd/protocol.c.
3375 * Implemented the public key authentication in the initiator side
3376 in the server. Affected file silcd/protocol.c.
3378 * Removed the [RedirectClient] config section from the server
3379 configuration. Is not needed and I don't want to implement it.
3381 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Cleaned up the CMODE command in the server. It now works
3384 correctly and supports all the modes defined in the protocol.
3385 Affected file is silcd/command.c.
3387 * Added `hmac_name' field to the SilcChannelEntry in the server
3388 to hold the default HMAC of the channel. It can be set when
3389 creating the channel (with JOIN command). Affected files
3392 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3393 type to indicate the change of the current cipher and hmac
3394 on the channel. Client can safely ignore the <cipher> argument
3395 (if it chooses to do so) since the CHANNEL_KEY packet will
3396 force the channel key change anyway. The <hmac> argument is
3397 important since the client is responsible of setting the new
3398 HMAC and the hmac key into use.
3400 * Fixed the CMODE command in the client library as well.
3402 * Tested CMODE command in router environment successfully.
3404 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Show the version of the remote client (or server) when connecting
3407 to the server. It is logged to the log file. Affected file
3408 is silcd/protocol.c.
3410 * Fixed the KILLED notify handling in the client library. The
3411 client must be removed from all channels when receiving the
3414 Also, do not remove the client entry when giving the KILL
3415 command but when the KILLED notify is received.
3417 * Removed silc_idlist_find_client_by_nickname from the server.
3418 Not needed anymore. Affected files silcd/idlist.[ch].
3420 * Implemented the CHANNEL_CHANGE notify type handling to the
3421 server. Affected file silcd/server.c.
3425 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Added silc_server_send_notify_invite to send the INVITE
3428 notify between routers.
3430 * Implemented the INVITE command correctly to the server.
3432 * Implemented the INVITE notify type handling in the server.
3434 * Implemented the INVITE command to the client library and on the
3437 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Added function silc_server_get_client_resolve to find the
3440 client entry by ID from all ID lists and then resolve it
3441 (using WHOIS) if it cannot be found. Affected file is
3444 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Implemented the BAN command to the client library.
3448 * The JOIN command in the server now checks the invite list
3451 * Changed the silc_command_reply_payload_encode_va and the
3452 silc_command_payload_encode_va to support that if argument is
3453 NULL it ignores and checks the next argument. Affected file
3454 lib/silccore/silccommand.c.
3456 * Added silc_server_send_notify_ban to send the BAN notify
3457 type between routers.
3459 * Chaned the silc_notify_payload_encode to support that if
3460 argument is NULL it ignores and checks the next argument.
3461 Affected file lib/silccore/silcnotify.c.
3463 * Tested ban lists in router environment successfully.
3465 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Implemented BAN command to the server, in silcd/command.[ch].
3469 * Removed the BAN and INVITE_LIST modes from the CMODE command
3472 * Added function silc_string_match to regex match two strings.
3473 Affected files lib/silcutil/silcutil.[ch].
3475 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Redefined parts of the SilcChannelEntry in the server to support
3478 the new ban and invite lists.
3480 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Redefined the INVITE command. The same command can be used to
3483 invite individuals to the channel but also to manage the invite
3484 list of the channel (to add to and remove from the invite list).
3485 Updated the protocol specs.
3487 * Added new command SILC_COMMAND_BAN that can be used to manage
3488 the ban list of the channel. Updated the protocol specs.
3490 * Removed the channel modes: the SILC_CMODE_BAN and the
3491 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3492 in the CMODE command. The equivalent features are now available
3493 using INVITE and BAN commands. Updated the protocol specs.
3495 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3496 in the network about change in the current ban list. The notify
3497 type is not used by the client.
3499 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3500 support the invite lists.
3502 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Added new function silc_string_regexify that converts string
3505 including wildcard characters into regex string that can
3506 be used by the GNU regex library. Added into the file
3507 lib/silcutil/silcutil.[ch].
3509 Added silc_string_regex_combine to combine to regex strings
3510 into one so that they can be used as one regex string by
3511 the GNU regex library. Added into the file
3512 lib/silcutil/silcutil.[ch].
3514 Added silc_string_regex_match to match two strings. It returns
3515 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3517 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Imported GNU regex to the soruce tree into lib/contrib.
3520 Fixed some compiler warning from the regex.c.
3522 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Fixed MOTD command in the server to work in router environment.
3526 * Fixed the MOTD command in the client library to support
3527 the server argument in the command.
3529 * Added `nickname_len' argument to the silc_idlist_add_client
3530 in the server, as the `nickname' argument may be binary data
3533 * Added silc_idlist_get_channels to return all channels from
3536 * Implemented LIST command to the server. Affected file is
3539 * Implemented the LIST command to the client library and on the
3542 * Added [<user count>] argument to the LIST command reply.
3543 With private channels the user count is not shown.
3545 * Updated TODO and README.
3547 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * The client entry's data.registered must be TRUE even with
3550 global client entry on global client list. The data.registered
3551 is used to check whether the client is anymore in the network,
3552 for example with WHOWAS command so it must be valid.
3554 * Fixed the WHOWAS command in the server. It now actually works
3555 in router environment. Added function into silcd/command_reply.c
3556 silc_server_command_reply_whowas_save.
3558 * Added silc_idlist_purge function to the silcd/idlist.c
3559 to periodically purge the ID Cache.
3561 * Fixed INFO command in the server. It works now in router
3562 environment. Added <server name> argument to the INFO command
3563 reply. Updated the protocol specs.
3565 * Fixed minor bug in silc_idcache_purge to not purge if the
3566 expire value is zero.
3568 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3569 they were buggy because of the WHOWAS information.
3571 * Fixed local command MSG to handle the async resolving of
3572 the remote client properly. It used to fail the first MSG.
3573 Affected file silc/local_command.c.
3575 * Added `data_len' field to SilcIDCache context.
3577 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Update TODO. Todo in commands in the server.
3581 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3584 used by routers as broadcast packet to inform other routers
3585 about the changed user mode.
3587 Implemented the notify handling in the server. Affected file is
3588 silcd/packet_receive.c. Added the function
3589 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3591 * Added new generic Channel Payload and deprecated the New Channel
3592 Payload. The New Channel Payload is now the generic Channel
3595 * Added new argument `mode' to the silc_server_send_new_channel
3596 as it is required in the Channel Payload now.
3598 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3599 and created a new and real SilChannelPayload to represent the
3600 new generic Channel Payload. Implemented the encode/decode
3601 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3603 * Added silc_server_get_client_channel_list to return the list
3604 of channels the client has joined for WHOIS command reply.
3605 Affected file silcd/server.[ch].
3607 * Implemented the channel list sending in the WHOIS command reply
3608 in server and in the client.
3610 Implemented the channel list displaying on the user interface
3611 as well. Affected file silc/client_ops.c.
3613 * Added silc_channel_payload_parse_list to parse list of Channel
3614 Payloads. It returns SilcDList list of SilcChannelPayloads.
3615 Client for example can use this function to parse the list of
3616 channels it receives in the WHOIS command reply. The caller
3617 must free the list by calling silc_channel_payload_list_free.
3618 Affected files lib/silccore/silcchannel.[ch].
3620 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added one new argument <user mode> to the WHOIS command reply
3623 to return the mode of the user in SILC. Updated the protocol
3626 Implemented it to the server and client.
3628 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Fixed the mode printing on the user interface on joining.
3631 Affected file silc/client_ops.c.
3633 * Implemented the UMODE command and user modes in general to the
3634 client library and to the user interface.
3636 * Implemented the UMODE command to the server.
3638 * The server now sends UNKNOWN_COMMAND error status if client sends
3639 unknown command. Affected file silcd/command.c.
3641 * All server commands now handle the command identifier the right
3642 way when sending the command reply to the client. The client can
3643 use to identify the command replies with the identifier.
3645 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Added silc_server_get_client_route to resolve the route to
3648 the client indicated by the client ID. Affected file is
3651 * Added silc_server_relay_packet as general function to relay
3652 packet to arbitrary destination. This deprecates functions
3653 like _send_private_message_key, _relay_notify etc. Affected
3654 file is silcd/packet_send.[ch].
3656 Removed silc_server_send_key_agreement,
3657 silc_server_send_private_message_key and
3658 silc_server_packet_relay_notify functions from the file
3659 silcd/packet_send.[ch].
3663 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3664 server. Affected file silcd/packet_receive.[ch].
3666 * Implemented the KILL command to the client. Implemented the
3667 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3668 Affected files lib/silcclient/command[_reply].c and
3669 lib/silcclient/client_notify.c. Implemented the KILL notify
3670 printing in the user inteface.
3672 * Fixed a lot silc_parse_nick memory leaks from the client
3673 library in the file lib/silcclient/command.c.
3675 * Changed the silc_server_send_notify_on_channels's `sender'
3676 argument from SilcSocketConnection to SilcClientEntry to
3677 check the sender as entry and not as connection object and not
3678 to send to the client provided as argument. The affected file
3679 is silcd/packet_send.[ch].
3681 * The notify packets that are destined directly to the client used
3682 to not to be processed by the server. Now changed that and the
3683 server processes all notify packets. After relaying the packet
3684 to the client the notify packet is processed in the server.
3686 * The silc_server_free_client_data now checks whether there is
3687 pending outgoing traffic for the client and purges the data to
3688 the network before removing the client entry.
3690 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3693 an client is killed from the SILC Network. Updated the protocol
3696 Added new function silc_server_send_notify_killed to the
3697 silcd/packet_send.[ch].
3699 * Added function silc_server_packet_relay_notify to relay notify
3700 packets that are destined directly to a client. In this case
3701 the server does not process the notify packets but merely relays
3702 it to the client. Affected file silcd/packet_send.[ch].
3704 Added also silc_server_packet_process_relay_notify to check
3705 whereto relay the notify. Affected file is
3706 silcd/packet_receive.[ch].
3708 * Implemented the KILL command to the server.
3712 * Added the backup schema desgined last fall to the protocol
3713 specs for everyone to see. The specification is in the
3714 *-spec-xx.txt draft and the packet type definitions for the
3715 backup routers is in *-pp-xx.txt draft. Thusly, added also
3716 new packet type SILC_PACKET_CELL_ROUTERS.
3718 * A big security problem in the implementation discovered. The
3719 signoff of an client did not cause new channel key generation
3720 which it of course should've done. The channel keys must be
3721 always re-generated when client leaves (or signoffs) the channel.
3722 The silc_server_remove_from_channels funtion now handles
3723 the channel key re-generation.
3725 * Added `sender' argument to the silc_server_send_notify_on_channels
3726 to not to send the client provided as argument. Affected file
3727 silcd/packet_send.[ch].
3729 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Implemented OPER and SILCOPER commands into the server and
3734 * Added silc_auth_verify and silc_auth_verify_data to verify
3735 the authentication directly from the authentication payload.
3736 It supports verifying both passphrase and public key based
3737 authentication. Affected file lib/silccore/silcauth.[ch].
3739 * Added `hash' field to the SilcIDListData structure. It is the
3740 hash negotiated in the SKE protocol. Affected file is
3743 * Slight redesigning of the SilcAuthPayload handling routines.
3744 Do not send SilcPKCS but SilcPublicKey as argument.
3746 * Implemented the public key authentication support to the
3747 serverconfig. The public key is loaded from the provided path
3748 and saved as authentication data to void * pointer. Thus,
3749 changed the unsigned char *auth_data to void *auth_data;
3751 * Fixed SHUTDOWN command to send the reply before the server
3752 is shutdown. :) Affected file silcd/command.c.
3754 * Fixed fatal bug in CONNECT command. The hostname was invalid
3755 memory and server crashed. Affected file silcd/command.c.
3757 * Fixed fatal bug in CLOSE command. The server_entry became
3758 invalid but was referenced later in the command. Affected file
3761 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed fatal bug in failure packet handling. Server ignored
3764 the failure and thus crashed when it came.
3768 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3771 that the command may be executed only once in (about) 2 seconds.
3772 The old SILC_CF_LAG flag is same but allows command bursts up
3773 to five before limiting.
3775 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3776 server code. Various commands now includes the CF_LAG_STRICT
3777 flag to disallow any kind of miss-use of the command.
3779 * Fixed the silc_buffer_unformat to not to allocate any data
3780 if the length of the data is zero. It used to allocate the
3781 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3783 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Changed the format of AdminConnection configuration section
3786 in the server. Added username of the admin to the format.
3787 Affected files silcd/serverconfig.[ch].
3789 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3790 to return admin configuration data by host, username and/or
3793 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Implemented WHOWAS command to the server. Added the functions:
3797 silc_server_command_whowas_parse,
3798 silc_server_command_whowas_send_reply,
3799 silc_server_command_whowas_from_client and
3800 silc_server_command_whowas_from_server
3802 * Added <Client ID> argument to the WHOWAS command reply. Updated
3803 the protocol specs accordingly.
3805 * Implemented WHOWAS command and command_reply to the client
3808 Implemented the WHOWAS printing on the user interface.
3810 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Added new argument to the WHOWAS command reply, the real name.
3813 It is an optional argument. Updated the protocol specs.
3815 * Added SilcIDCacheDestructor callback that is registered when
3816 the SilcIDCache is allocated. The callback is called when
3817 an cache entry in the ID Cache expires, or is purged from the
3818 cache. Added into lib/silccore/idcache.[ch].
3820 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3821 to destruct the client entries when the cache entry expires.
3822 Other ID Cache's in server and in the client library ignores
3825 * If the ID Cache entry's `expire' field is zero then the entry
3826 never expires. Added boolean `expire' argument to the
3827 silc_idcache_add function in the lib/silccore/idcache.[ch].
3828 If it is TRUE the default expiry value is used.
3830 * Added silc_server_free_client_data_timeout that is registered
3831 when client disconnects. By default for 5 minutes we preserve
3832 the client entry for history - for WHOWAS command.
3834 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added support to the server to enforce that commands are not
3837 executed more than once in 2 seconds. If server receives
3838 commands from client more frequently, timeout is registered
3839 to process the commands. Affected file silcd/command.c.
3840 Added new function silc_server_command_process_timeout.
3842 * Changed NICK_NOTIFY handling in client library to check that
3843 if the client's nickname was changed, so there is no need to
3844 resolve anything from the server.
3846 * Removed error printing from the WHOIS and IDENTIFY commands.
3847 If error occurs then it is ignored silently in the client library.
3848 The application, however, may map the received error to
3849 human readable error string. The application currently maps
3850 the NO_SUCH_NICKNAME error to string.
3852 * Made the command status message public to the application. Moved
3853 them from lib/silcclient/command_reply.c to
3854 lib/silcclient/command_reply.h. The application can map the
3855 received command status to the string with the
3856 silc_client_command_status_message function.
3858 * Added check to the server to check that client's ID is same
3859 as the Source ID in the packet the client sent. They must
3862 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added dist-bzip hook to the Makefile.am to make bzip2
3865 compressed distributions.
3867 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Server now enforces the maximum length for the nickname and
3870 the channel as protocol specification dictates. 128 bytes for
3871 nickname and 256 bytes for channel name.
3873 * Moved the WHOIS printing to the application. The client libary
3874 does not print out the WHOIS information anymore, the application
3875 must do it. Renamed silc_client_command_reply_whois_print to
3876 the silc_client_command_reply_whois_save.
3878 The client's idle time is also sent to the application now, and
3879 the idle is shown on screen.
3881 * Added silc_client_command_reply_identify_save to save the
3882 received IDENTIFY entries.
3884 * Do not check for channel private keys in message sending and
3885 reception if the channel does not have the PRIVKEY mode set.
3886 Affected file lib/silclient/client_channel.c.
3888 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3891 just surfaced after chaning the JOIN procedure.
3893 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Added silc_client_get_clients_by_list to get client entries
3896 from Client ID list, that is returned for example by JOIN
3897 and USERS command replies. The application should use this
3898 function for example when JOIN command reply is received to
3899 resolve the clients already on the channel (library does not
3900 do that anymore as USERS command reply is not used in the JOIN
3901 procedure anymore). Affected files lib/silcclient/silcapi.h and
3902 lib/silcclient/idlist.c.
3904 * JOIN command reply and USERS command reply returns now SilcBuffer
3905 pointers instead of unsigned char pointers when returning
3906 the client list and mode list.
3908 * Added <Client ID> argument to the JOIN command reply, mainly
3909 for the server to identify for which client the command was
3910 originally sent. Updated protocol specs accordingly.
3912 * Added SilcDlist private_key pointer to the SilcChannelEntry
3913 in the client to support the channel private keys. Affected
3914 file is lib/silcclient/idlist.h.
3916 * Added SilcChannelPrivateKey argument to the function
3917 silc_client_send_channel_message so that application can choose
3918 to use specific private ke if it wants to. If it is not provided,
3919 the normal channel key is used, unless private keys are set.
3920 In this case the first (key that was added first) is used
3921 as the encryption key.
3923 * Implemented the support for channel private key handling.
3924 Implemented the following functions:
3926 silc_client_add_channel_private_key,
3927 silc_client_del_channel_private_keys,
3928 silc_client_del_channel_private_key,
3929 silc_client_list_channel_private_keys and
3930 silc_client_free_channel_private_keys
3932 Affected file lib/silcclient/client_channel.c.
3934 * Added the support for the private keys in the channel message
3935 sending and encryption and in the message reception and
3936 decryption. Affected funtions are
3937 silc_client_send_channel_message and silc_client_channel_message.
3939 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Added SKE's key verify callback to the client library's
3942 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3944 * Removed the statement that server (or router) must send USERS
3945 command reply when joining to the channel so that the client
3946 knows who are on the channel. Instead, the client list and
3947 client's mode list is now sent in the JOIN command reply to the
3948 client who joined channel. This is better solution.
3950 * Added function silc_server_get_users_on_channel and function
3951 silc_server_save_users_on_channel to the silcd/server.[ch].
3953 * Removed function silc_server_command_send_users from the
3956 * Do not show topic on the client library anymore. The topic is
3957 sent in the command reply notify to the application and the
3958 application must show the topic now.
3960 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Added client searching by nickname hash into the IDENTIFY and
3963 WHOIS commands in the server as they were clearly missing from
3964 them. Affected file is silcd/command.c.
3966 * Fixed a bug in private message receiving in the client library.
3967 The remote ID was freed and it wasn't supposed, now it is
3970 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Minor fix to the channel payload; allocate the data area, as it
3973 needs to be of specific length.
3975 * If the key agreement port is zero then the operating
3976 system will define the bound port. Affected files are
3977 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3979 * Added new function silc_channel_payload_decrypt into the file
3980 lib/silccore/silcchannel.[ch].
3982 * Moved the channel message etc, check from silc_packet_decrypt
3983 to applications. The library calls now a generic
3984 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3985 when the packet is either normal or special. This was done to
3986 allow more wide range of checking that was not allowed when
3987 the code was in library. Now applications can do virtually any
3988 checks to the packet and return to the library the decision how
3989 the packet should be processed. Affected files are
3990 lib/silccore/silcpacket.[ch].
3992 Added silc_server_packet_decrypt_check to the server and
3993 silc_client_packet_decrypt_check to the client library.
3995 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3996 to send with specified source and destination information.
3998 * Channel message delivery between routers was broken after the
3999 channel key distribution was fixed earlier. The channel key
4000 was used be to distributed to other routers as well which is not
4001 allowed by the protocol. Now this is fixed and channel keys
4002 really are cell specific and the channel message delivery between
4003 routers comply with the protocol specification.
4005 * Fixed various commands in server to check also the global list
4006 for the channel entry and not just the local list. The affected
4007 file silcd/command.c.
4009 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Added assert()s to buffer formatting and unformatting routines
4012 to assert (if --enable-debug) when error occurs. Affected
4013 file: lib/silcutil/silcbuffmt.c.
4015 * Changed to auto-reconnect to check whether the remote host is
4016 router and register the re-connect timeout if it is. It used
4017 to check that whether we are normal server, but router must do
4018 auto-reconnect with another router as well. Affected file
4021 * Removed the [<key len>] option from CMODE command as the cipher
4022 name decides the key length, nowadays. See the defined ciphers
4023 from the protocol specification.
4025 * Added [<hmac>] option to the CMODE command to define the HMAC
4026 for the channel. Added SILC_CMODE_HMAC channel mode.
4028 * Added [<hmac>] option for the JOIN command so that user can
4029 select which HMAC is used to compute the MACs of the channel
4032 * Added Hmac field to the Channel Message Payload. The integrity
4033 of plaintext channel messages are now protected by computing
4034 MAC of the message and attaching the MAC to the payload. The
4035 MAC is encrypted. Now, it is clear that this causes some
4036 overhead to the size of the packet but rationale for this is that
4037 now the receiver can verify whether the channel message decrypted
4038 correctly and also when private keys are set for the channel the
4039 receiver can decrypt the packet with several keys and check from
4040 the MAC which key decrypted the message correctly.
4042 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4043 lib/silccrypt/silccipher.[ch].
4045 * Added silc_hash_len to return the digest length into the
4046 lib/silcrypt/silchash.[ch].
4048 * Rewrote parts of Silc Channel Payload interface in the
4049 lib/silccore/silcchannel.[ch]. The encode function now also
4050 encrypts the packet and parse function decrypts it.
4052 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Fixed a minor formatting bug in the SKE's key material processing.
4055 It actually might have processed the keys wrong way resulting
4058 * Redefined the mandatory HMAC algorithms and added new algorithms.
4059 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4060 and hmac-md5 truncated to 96 bits. The mandatory is now
4061 hmac-sha1-96. Rest are optional (including the one that used
4062 to be mandatory). Rationale for this is that the truncated HMAC
4063 length is sufficient from security point of view and can actually
4064 make the attack against the HMAC harder. Also, the truncated
4065 HMAC causes less overhead to the packets. See the RFC2104 for
4068 * Added new [hmac] configuration section. The SKE used to use
4069 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4070 is of course wrong. The official names that must be proposed in
4071 the SKE are the ones defined in the protocol specification
4072 (hmac-sha1-96 for example). The user can configure any hmac
4073 using any hash function configured in the [hash] section. At
4074 least, the mandatory must be configured.
4076 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4078 * Added HMAC list to the SKE proposal list. It has now both
4079 hash algorithm list and HMAC list. This makes the protocol
4080 incompatible with previous versions. The SKE now seems to work
4081 the way it is supposed to work, for the first time actually.
4083 * Defined plain Hash algorithms to the protocol specification.
4086 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Implemented support for key agreement packets into the server.
4089 Added functions silc_server_key_agreement and
4090 silc_server_send_key_agreement. Other than these functions,
4091 server has nothing to do with this packet.
4093 * Added support for private message key packets into the server.
4094 Added functions silc_server_private_message_key and
4095 silc_server_send_private_message_key.
4099 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4100 called in the protocol's final callback instead in the END
4101 protocol state. This makes a little more sense and in the same
4102 time in client we can use the same protocol routines for normal
4103 key exchange and to key agreement packet handling as well.
4105 * Added to both client's and server's KE protocol context the
4106 SilcSKEKeyMaterial pointer to save the key material. We will
4107 bring the key material to the protocol's final callback by doing
4108 this. The final callback must free the key material.
4110 * Added SKE's packet_send callback into client's KE protocol
4111 context so that the caller can choose what packet sending function
4112 is used. This way we can use different packet sending when
4113 doing normal SKE when doing key agreement packet handling (in
4114 the key agreement packet handling we do not want to encrypt
4117 * Implemented the responder side of the key agreement routines
4118 in the client. The client can now bind to specified port and
4119 accept incoming key negotiation. The key material is passed
4120 to the application after the protocol is over.
4122 * Implemented the processing of incoming Key Agreement packet
4123 in the client. Added function silc_client_key_agreement to
4126 * Implemented the intiator side of the key agreement routines
4127 in the client. The client can now initiate key agreement with
4128 another remote client. The key material is passed to the
4129 application after the protocol is over.
4131 * Created client_keyagr.c to include all the key agreement
4134 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4135 SILC_TASK_CALLBACK except that it is not static.
4137 * Created client_notify.c and moved the Notify packet handling
4138 from the client.[ch] into that file.
4140 * Created client_prvmsg.c and moved all private message and
4141 private message key routines from the client.[ch] into that file.
4143 * Create client_channel.c and moved all channel message and
4144 channel private key routines from the client.[ch] into that file.
4146 * Changed silc_client_get_client_by_id_resolve to resolve with
4147 WHOIS command instead of IDENTIFY command, in the file
4148 lib/silclient/idlist.c.
4150 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Implemented the SKE's responder side to the Client library.
4154 * When FAILURE is received to the protocol do not trust it
4155 blindly. Register a timeout to wait whether the remote closes
4156 the connection as it should do it, only after that process the
4157 actual failure. This was changed to both client and server.
4159 * Added client_internal.h to include some of the structures
4160 there instead of client.h in lib/silcclient/.
4162 * Added function silc_task_unregister_by_callback to unregister
4163 timeouts by the callback function.
4165 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Some "Incomplete WHOIS info" errors has been appearing on the
4168 log files. Took away the entry->userinfo check from WHOIS
4169 reply sending. The entry->userinfo is now " " if client did not
4170 provide one. I thought this was fixed earlier but something
4171 is wrong still. Let's see if the error still appears.
4173 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Fixed a minor bug in the login when the channel key is
4176 re-generated in the server. It used to generate the key in
4177 wrong order and thus caused problems in the channel traffic.
4179 * Fixed a minor bug in channel key distsribution after
4180 KICK command. The key was not sent to the router even though
4183 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Added silc_ske_process_key_material_data as generic routine
4186 to process any key material as the SILC protocol dictates. The
4187 function is used by the actual SKE library but can be used by
4188 applications as well. This relates to the private message keys
4189 and the channel private keys since they must be processed the
4190 same way the normal SILC session keys. The protocol dictates
4191 this. Affected files: lib/silcske/silcske.[ch].
4193 Added also silc_ske_free_key_material to free the
4194 SilcSKEKeyMaterial structure.
4196 * Defined silc_cipher_set_key function to set the key for
4197 cipher without using the object's method function. The affected
4198 files: lib/silccrypt/silccipher.[ch].
4200 * Implemented silc silc_client_add_private_message_key,
4201 silc_client_add_private_message_key_ske,
4202 silc_client_del_private_message_key,
4203 silc_client_list_private_message_keys and
4204 silc_client_free_private_message_keys functions in the
4207 Added functions silc_client_send_private_message_key to send
4208 the Private Message Key payload and silc_client_private_message_key
4209 to handle incoming Private Message Key payload.
4211 * Added Cipher field to the Private Message Key payload to set
4212 the cipher to be used. If ignored, the default cipher defined
4213 in the SILC protocol (aes-256-cbc) is used.
4215 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Removed lib/silcclient/ops.h file.
4219 Redefined parts of the SILC Client Library API. Created new
4220 file silcapi.h that deprecates the ops.h file and defines the
4221 published Client Library API. Defined also private message key
4222 API and channel private key API into the file.
4224 This is the file that the application must include from the
4225 SILC Client Library. Other files need not be included by
4226 the application anymore.
4228 * Added new key_agreement client operation callback and also
4229 defined the Key Agreement library API for the application.
4231 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4234 is used by clients to request key negotiation between another
4235 client in the SILC network. If the negotiation is started it
4236 is performed using the SKE protocol. The result of the
4237 negotiation, the secret key material, can be used for example
4238 as private message key.
4240 Implemented the Key Agreement payload into the files
4241 lib/silccore/silauth.[ch].
4243 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Redefined ciphers for the SILC protocol. Added some new ciphers
4246 and defined the key lengths for the algorithms. Changed the
4247 code accordingly. The default key length is now 256 bits.
4249 * Fixed SKE key distribution function silc_ske_process_key_material
4250 when the key length is more than 128 bits. The default key
4251 length in SILC is now 256 bits.
4253 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4254 to indicate unsupported algorithm.
4256 * Renamed rijndael.c to aes.c and all functions as well.
4258 * Fixed a long standing channel key setting bug in client library.
4259 Weird that it has never surfaced before.
4261 * Fixed bug in channel deletion. If the entire channel is removed
4262 then it must also delete the references of the channel entry
4263 from the client's channel list as the client's channel entry and
4264 the channel's client entry share same memory.
4266 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Implemented CONNECT and SHUTDOWN commands in the client.
4270 * Implemented CLOSE command to the client.
4272 * Added the function silc_idlist_find_server_by_name into the
4273 files silcd/idlist.[ch].
4275 Added the function silc_idlist_find_server_by_conn into the
4276 files silcd/idlist.[ch].
4278 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * DIE command was renamed to SHUTDOWN. Updated the both code
4283 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4284 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4286 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4289 * Added function silc_server_create_connection function to create
4290 connection to remote router. My server implementation actually
4291 does not allow router to connect to normal server (it expects
4292 that normal server always initiates the connection to the router)
4293 so the CONNECT command is only good for connecting to another
4296 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4299 or some other client was kicked from the channel.
4301 Implemented the handling of the notify type to both client
4304 Implemented silc_server_send_notify_kicked to send the KICKED
4305 notify. It is used to send it to the server's primary router.
4307 * Implemented the KICK command into server and client.
4309 * Added `query' argument to the silc_idlist_get_client function
4310 to indicate whether to query the client from server or not if
4313 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4314 to indicate that the client is not channel founder.
4318 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Removed the rng context from SilcPacketContext structure and
4321 changed that the packet routine uses the Global RNG API.
4323 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Added support for quit message that client can "leave" on the
4326 channel when it quits the SILC. It is ditributed inside the
4327 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4329 Added silc_server_free_client_data that will take the
4330 signoff message as argument.
4332 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4334 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Updated parts of the protocol specification to keep it up
4339 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4342 payloads in one packet.
4344 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4345 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4346 use now the new List flag.
4348 * Also deprecated the following packet types: REPLACE_ID,
4349 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4351 * Added list support for Notify packet in server.
4353 * Added silc_server_send_notify_channel_change to send the
4354 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4355 the silc_server_send_replace_id.
4357 * Added silc_server_send_notify_nick_change to send the
4358 NICK_CHANGE notify type. Deprecates the function
4359 silc_server_send_replace_id.
4361 * Added silc_server_send_notify_join to send the JOIN notify type.
4362 Deprecates the function silc_server_send_new_channel_user.
4364 * Added silc_server_send_notify_leave to send LEAVE notify type.
4365 Deprecates the function silc_server_send_remove_channel_user.
4367 * Added silc_server_send_notify_cmode and
4368 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4369 types. Deprecates the silc_server_send_set_mode function.
4371 * Added SERVER_SIGNOFF notify type to indicate that server has
4372 quit. This means that all clients on the channel from that
4373 server will drop. This can be also used when netsplit happens.
4375 Deprecated REMOVE_ID packet type since it is not needed anymore
4378 Added silc_server_send_notify_server_signoff to send the
4379 SERVER_SIGNOFF notify type. Deprecates the function
4380 silc_server_send_remove_id.
4382 Added also silc_server_send_notify_signoff to send the
4383 SIGNOFF notify type.
4385 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4386 SILC protocol from this day on. Changed the protocol
4387 specification as well.
4389 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4390 notify type. It is used between routers to notify about
4391 topic changes on a channel.
4393 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4396 * Partly updated the protocol specification to comply with the
4397 changes now made. It is still though a bit outdated.
4399 * The JOIN notify type now takes one extra argument <Channel ID>.
4400 The packet used to be destined to the channel but now the
4401 JOIN type may be sent as list thus it is impossible to
4402 destine it to any specific channel. By adding this argument
4403 it is again possible.
4405 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Added CREDITS file. The CHANGES and CREDITS file will appear
4408 in the distribution as well.
4410 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4413 types in the server's silcd/packet_receive.c.
4415 * Implemented CMODE and CUMODE to work in router environment.
4417 * Fixed minor encoding and decoding buglet from the
4418 lib/silccore/silcmode.c.
4420 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4423 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4425 * Changed all SilcConfigServer* and silc_config_server* to
4426 SilcServerConfig* and silc_server_config*, respectively.
4429 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Associated the ID (client or server ID) to the Authentication
4432 Payload to avoid any possibility of forging. Updated the
4433 protocol specification and the code accordingly.
4435 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * The RSA key length is now save to the RsaKey context in the
4438 key generation process in lib/silccrypt/rsa.c. The key length
4439 is now used to figure out the maximum size of the block allowed
4440 to be encrypted/signed.
4442 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4443 is equivalent to the silc_mp_mp2bin but does not allocate any
4446 * Changed silc_mp_mp2bin API to take length argument. If it is
4447 non-zero then the buffer is allocated that large. If zero, then
4448 the size is approximated using silc_mp_sizeinbase, which however
4451 * Created Global RNG API which is global RNG that application can
4452 initialize. After initializing, any routine anywhere in the
4453 code (including library) can use RNG without allocating a new
4454 RNG object. This was done to allow this sort of use of the
4455 RNG in code that has no chance to allocate RNG object. All
4456 applications currently allocate this and many routines in the
4457 library use this. Affected file lib/silccrypt/silcrng.[ch].
4459 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4460 it to use the Global RNG API.
4462 * Defined Authentication Payload into protocol specification that
4463 is used during SILC session to authenticate entities. It is
4464 used for example by client to authenticate itself to the server
4465 to obtain server operator privileges.
4467 Implemented this payload into the lib/silccore/silcauth.[ch].
4468 Implemented also routines for public key based authentication
4469 as the new protocol specification dictates.
4471 Moved definitions of different authentication methods from
4472 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4474 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4475 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4476 silc_pkcs_verify_with_hash functions into the file
4477 lib/silccrypt/silcpkcs.[ch].
4479 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * The client entry's userinfo pointer must be always valid.
4482 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4483 will fail since it requires the userinfo. Now, the userinfo
4484 is allocated as "" if actual userinfo does not exist. Actually,
4485 it must exist and it is totally Ok to drop client connections
4486 that does not announce the userinfo. However, we will make
4487 this workaround for now.
4489 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4490 to return the remote port by socket.
4492 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4495 SILC_SERVER_PENDING_EXEC and added an new macro
4496 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4497 data or when error occurs while processing the pending command.
4499 Added new argument `destructor' into silc_server_command_pending
4500 and to the SilcServerCommandPending object. This destructor is
4501 now called after calling the pending callback or if error occurs
4502 immediately. If error occurs the actual pending callback won't
4503 be called at all - only the destructor. The destructor may be
4504 NULL if destructor is not needed.
4506 All this applies for client library code as well. Similar
4507 changes were made there as well for the pending commands.
4509 In the client, the application must now allocate the
4510 SilcClientCommandContext with the silc_client_command_alloc
4513 * Added reference counter to the SilcServerCommandContext. Added
4514 function silc_server_command_alloc and silc_server_command_dup
4517 Same type of functions added to the client library for the same
4520 * Removed the cmd_ident from IDListData away since it is now
4521 global for all connections. It is the command identifier used
4522 in command sending and with pending commands. The affected file
4525 * Added reference counter to the SilcSocketConnection objecet to
4526 indicate the usage count of the object. The object won't be
4527 freed untill the reference counter hits zero. Currently only
4528 server uses this, and client ignores it. The client must be
4529 set to use this too later. The affected files are
4530 lib/silccore/silcsockconn.[ch]. Added also the function
4531 silc_socket_dup to increase the reference counter.
4533 This was mainly added because it is possible that the socket
4534 is removed underneath of pending command or other async
4535 operation. Now it won't be free'd and proper DISCONNECTING
4536 flags, etc. can be set to avoid sending data to connection that
4537 is not valid anymore.
4539 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4540 the connection. After that it sets SILC_SET_DISCONNECTED.
4541 It is, however, possible that the socket data is not still freed.
4542 The silc_server_packet_process now checks that data is not
4543 read or written to connection that is DISCONNECTED. The socket
4544 get's freed when the reference counter hits zero.
4546 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Changed the client operation API: channel_message operation's
4549 `sender' is now the client entry of the sender, not the nickname
4550 and the `channel' is the channel entry, not the channel name.
4552 In the private_message operation the `sender' is now also the
4553 client entry of the sender not the nickname.
4555 Affected file is lib/silcclient/ops.h and all applications
4556 using the client operations.
4558 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Moved the calling of ops->connect() from connect_to_server_final
4561 into receive_new_id functin since that is the point when the
4562 client is actually allowed to send traffic to network. The
4563 affected file is lib/silcclient/client.c.
4565 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4568 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4569 (if needs broadcasting) instead of broadcasting the packets one
4570 by one which would make a burst in the network traffic.
4572 * Added `broadcast' argument to the functions in silcd/server.[ch]
4573 silc_server_create_new_channel[_with_id] to indicate whether
4574 to send New Channel packet to primary router.
4576 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Added new function into the silcd/server.[ch] files:
4579 silc_server_create_new_channel_with_id to create new channel with
4580 already existing Channel ID.
4582 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4583 lib/silccore/silcpacket.h. This packet is used t send list of
4584 Set Mode payloads inside one packet. Server uses this to set
4585 the modes for the channels and clients on those channels, that it
4586 announced to the router when it connected to it. The protocol
4587 specification has been updated accordingly.
4589 * The silc_server_new_channel did not handle the packet coming
4590 from normal server as it normally does not send that. However,
4591 when it announces its channels it does send it. Implemented
4592 the support for that.
4594 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4595 into the file lib/silccore/id.h.
4597 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Fixed memory leaks in the functions silc_idlist_del_client,
4600 silc_idlist_del_channel and silc_idlist_del_server in the file
4601 silcd/idlist.c. All of those leaked like a sieve.
4603 * Fixed some small memory leaks in the client's function
4604 silc_client_notify_by_server.
4606 * Added functions into silcd/server.c: silc_server_announce_clients,
4607 silc_server_announce_channels and silc_server_announce_server.
4608 These functions are used by normal and router server to announce
4609 to its primary router about clients, channels and servers (when
4610 router) that we own. This is done after we've connected to the
4613 These functions effectively implements the following packet types:
4614 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4615 and SILC_PACKET_NEW_ID_LIST.
4617 * Added new functions into the silcd/packet_receive.[ch]:
4618 silc_server_new_id_list, silc_server_new_channel_list and
4619 silc_server_new_channel_user_list to handle the incoming
4620 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4622 * Added support of changing Channel ID in the function
4623 silc_server_replace_id. If the server that announces a channel
4624 to the router already exists in the router (with same name but
4625 with different Channel ID), router is responsible to send
4626 Replace ID packet to the server and force the server to change
4627 the Channel ID to the one router has.
4629 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4630 client that the Channel ID has been changed by the router. The
4631 normal server sends this to the client. Client must start using
4632 the new Channel ID as the channel's ID.
4634 Implemented handling of this new type into lib/silcclient/client.c
4635 into the function silc_client_notify_by_server.
4637 * Added new function silc_idlist_replace_channel_id into the files
4638 silcd/idlist.[ch] to replace the Channel ID.
4640 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Call silc_server_command_identify_check always when processing
4643 the IDENTIFY command in silcd/command.c
4645 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4648 send keepalive packets. The packet can be sent by clients,
4649 servers and routers.
4651 Added function silc_socket_set_heartbeat into the file
4652 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4653 If not set, the heartbeat is not performed. The actual
4654 heartbeat is implemented in the low level socket connection
4655 library. However, application is responsible of actually
4658 Added silc_server_send_heartbeat to send the actual heartbeat
4659 packet into silcd/packet_send.[ch]. Server now performs
4660 keepalive with all connections.
4662 * Added silc_task_get_first function into lib/silcutil/silctask.c
4663 to return the timeout task with shortest timeout. There was a bug
4664 in task unregistration that caused problems. TODO has been
4665 updated to include that task system must be rewritten.
4667 * The client library will now resolve the client information when
4668 receiving JOIN notify from server for client that we know but
4669 have incomplete information.
4671 * Rewrote parts of silc_server_remove_from_channels and
4672 silc_server_remove_from_one_channel as they did not remove the
4673 channel in some circumstances even though they should've.
4675 * Encryption problem encountered in server:
4677 The LEAVE command used to send the Channel Key packet to the
4678 router immediately after generating it. However, the code
4679 had earlier sent Remove Channel user packet but not immediately,
4680 ie. it was put to queue. The order of packets in the router
4681 was that Channel Key packet was first and Remove Channel User
4682 packet was second, even though they were encrypted in the
4683 reverse order. For this reason, MAC check failed. Now, this
4684 is fixed by not sending the Channel Key packet immediately but
4685 putting it to queue. However, this is more fundamental problem:
4686 packets that are in queue should actually not be encrypted
4687 because packets that are sent immediately gets encrypted
4688 actually with wrong IV (and thus MAC check fails). So, packets
4689 that are in queue should be encrypted when they are sent to
4690 the wire and not when they put to the queue.
4692 However, the problem is that the current system has not been
4693 designed to work that way. Instead, the packet is encrypted
4694 as soon as possible and left to the queue. The queue is then
4695 just purged into wire. There won't be any fixes for this
4696 any time soon. So, the current semantic for packet sending
4699 o If you send packet to remote host and do not force the send
4700 (the packet will be in queue) then all subsequent packets to the
4701 same remote host must also be put to the queue. Only after the
4702 queue has been purged is it safe again to force the packet
4705 o If you send all packets immediately then it safe to send
4706 any of subsequent packets through the queue, however, after
4707 the first packet is put to queue then any subsequent packets
4708 must also be put to the queue.
4710 Follow these rules and everything works fine.
4712 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Added new function silc_server_remove_clients_by_server to
4715 remove all client entries from ID list when the server connection
4716 is lost. In this case it is also important to invalidate all
4717 client entires as they hold the invalid server entry. This
4718 fixes fatal bug when server has lost connection and will reconnect
4721 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Made some sanity checks to silc_server_daemonise like to check
4724 whether the requested user and group actually exists.
4726 * Added sanity check to SKE's silc_ske_responder_finish to check
4727 that the public and private key actually is valid.
4729 * Invalidate the client's nickname when receiving Replace ID
4730 packet and the Client ID is being replaced. This means that the
4731 server will query the nickname if someone needs it (client)
4734 * Sort the ID Cache in client library when the ID Cache data
4735 has changed (needs sorting).
4737 * Do not allow for SILC client to create several connections to
4738 several servers. The client does not support windows right now
4739 and generating multiple connections causes weird behaviour.
4741 Irssi-silc client does support windows and can handle several
4742 connections without problems, see: www.irssi.org and SILC plugin.
4744 * Fixed some places where client was added to the IDList. The
4745 rule of thumb is following (in order to get everything right):
4746 If the client is directly connected local client then the
4747 `connection' argument must be set and `router' argument must be
4748 NULL to silc_idlist_add_client function. If the client is not
4749 directly connected client then the `router' argument must
4750 bet set and the `connection' argument must be NULL to the
4751 silc_idlist_add_client function.
4753 * The funtion silc_server_packet_send_local_channel actually did
4754 not check whether the client was locally connected or not. It
4755 does that now. Fixed a bug related to LEAVE command.
4757 * Fixed Remove Channel User payload parsing bug in server's
4758 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4760 * The server's silc_server_save_channel_key now checks also the
4761 global ID list for the channel as it might not be in the local
4762 list. Fixed a bug related to LEAVE command.
4764 * Is this the end of the [<unknown>] buglet that has been lurking
4765 around for a long time? A little for loop fix in server's
4766 silc_server_command_whois_parse that is used by both IDENTIFY
4767 and WHOIS command. At least, this was a clear bug and a cause
4768 of one type of [<unknown>] buglet.
4770 * WHOIS and IDENTIFY commands call the function
4771 silc_server_command_[whois/identify]_check function even if
4772 we are not router server.
4774 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Added --with-gmp configuration option. If set the GMP
4777 is always compiled in the SILC source tree. If not set then
4778 it is checked whether the system has the GMP3 installed. If
4779 it has then the GMP won't be compiled (the system's headers
4780 and library is used), if it doesn't have it then the GMP is
4781 compiled in the SILC source tree.
4783 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Changed RSA private exponent generation to what PKCS #1
4786 suggests. We try to find the smallest possible d by doing
4787 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4788 not security fix but optimization.
4790 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Added new config entry [Identity] to fork the server and run
4793 it as specific user and group. A patch from Bostik.
4795 * Imported Dotconf configuration library into lib/dotconf.
4796 This will be used to create the SILC configuration files later.
4797 It will appear in the distsribution after this commit.
4799 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * A big code auditing weekend happening. Auditing code for
4802 obvious mistakes, bugs and errors. Also, removing any code
4805 Removed files for being obsolete:
4807 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4808 inline in the file lib/silcutil/silcbuffer.h)
4810 o lib/silcutil/silcbufutil.c (the header has inline versions)
4812 Changed code to fix possible error conditions:
4814 o The buffer formatting routines now check that the destination
4815 buffer really has enough space to add the data. This applies for
4816 both buffer formatting and unformatting
4817 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4818 unformatting was changed to accomodate following rules:
4819 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4820 sent to the function while XXX_*STRING will not allocate or copy
4821 the data into the buffer. Instead it sets the pointer from the
4822 buffer into the pointer sent as argument (XXX_*STRING used to
4823 require that the pointer must be allocated already). This change
4824 makes this whole thing a bit more consistent and more optimized
4825 (note that the data returned in the unformatting with XXX_*STRING
4826 must not be freed now). The routines return now -1 on error.
4828 o Tried to find all code that use buffer_format and buffer_unformat
4829 and added return value checking to prevent formatting and
4830 especially unformatting errors and possible subsequent fatal
4833 o Changed ske->x and ske->KEY to mallocated pointers in
4834 lib/silcske/silcske.h. Fixed possible data and memory leak.
4836 o Added return value checking to all *_parse* functions. Fixed
4837 many memory leaks as well.
4839 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4840 so that buffer overflows would not happen. All code now also
4841 checks the return value as it can fail.
4843 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Added reconnection support to server if the normal server looses
4846 its connection to the router (for example if router is rebooted).
4847 The server performs normal reconnection strategy implemented
4848 to the server. Affected file silcd/server.c.
4850 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added new packet type SILC_PACKET_SET_MODE that is used to
4853 distribute the information about changed modes (for clients,
4854 channels and clients channel modes) to all routers in the
4855 network. Updated the protocol specification accordingly.
4857 Added functions into silcd/packet_send.c and
4858 silcd/packet_receive.c: silc_server_send_set_mode,
4859 silc_server_set_mode.
4861 Added new files silcmode.[ch] into lib/silccore that implements
4862 the encoding and decoding of Set Mode Payload. Added new type
4863 SilcSetModePayload. Moved the definitions of different modes
4864 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4866 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Oops, a little mistake in server's connection authentication
4869 protocol. The protocol is not ended with FAILURE but with
4870 SUCCESS if the authentication is Ok. :) Affected file is
4873 * Implemented NICK_CHANGE notify handling in server in the file
4874 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4875 the local clients on the channel. After the changing nickname
4876 in router environment snhould work and the [<unknown>] nickname
4877 should appear no more.
4879 The silc_server_replace_id function that receives the Replace ID
4880 payload now sends the NICK_CHANGE notify type also in the file
4881 silcd/packet_receive.c
4883 * Changed WHOIS and IDENTIFY command to support the maximum amount
4884 of arguments defined in protocol specs (3328 arguments). This
4885 fixed a bug that caused problems when there were more than three
4888 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Added extra parameter, command identifier, to the
4891 silc_client_send_command so that explicit command identifier
4894 Changed that ID list routines uses specific command identifier
4895 when sending WHOIS/IDENTIFY requests to the server so that they
4896 can be identified when the reply comes back.
4898 Affected files lib/silcclient/command.[ch],
4899 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4901 * Added `sender' argument to silc_server_packet_send_to_channel
4902 to indicaet the sender who originally sent the packet to us
4903 that we are now re-sending. Ignored if NULL. Affected file
4904 silcd/packet_send.[ch].
4906 * Added some server statistics support in silcd/server_internal.h
4907 SilcServerStatistics structure and around the server code. Also
4908 send some nice statistics information when client is connecting
4911 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Fixed channel ID decoding in server's JOIN command reply in
4914 silcd/command_reply.c
4916 * Fixed braodcasting of replace ID payload to not to send it if
4917 we are standalone server in silcd/packet_receive.c.
4919 * Fixed all channel message sending routines to not to send
4920 packets to clients that has router set, since they are routed
4921 separately in the same function earlier. Affects file
4922 silcd/packet_send.c and all channel packet sending functions.
4924 * In USERS reply, res_argv[i] are not allocated, the table
4925 is allocated. Thus changed that free the table, not its
4928 * In server's whois_check and identify_check if the client is
4929 locally connected do not send any WHOIS commands - they are not
4932 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Fixed some minor bugs in client when sending WHOIS command. The
4935 arguments was in wrong order.
4937 * Removed statis function add_to_channel from server in
4938 silcd/command.c that was previously used with the joining but
4941 * Tested USERS command in router environment successfully with two
4942 routers, two servers and two clients.
4944 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Reorganized the USERS command and command reply in client library
4947 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4948 When the command is given by user we register a pending command
4949 callback that will reprocess the command after the reply has been
4950 received from the server. When reprocessing the packet we then
4951 display the information. Thus, the USERS information is displayed
4952 now in the command callback instead of in the command reply
4953 callback. The processing of the command is same as previously
4954 when server has sent the command reply in the JOINing process.
4956 * Added to USERS command in silcd/command_reply.c to join the client,
4957 we didn't use to know about, to the channel after we've created
4958 a client entry for it. Also, for clienet we did know already still
4959 check whether it is on the channel or not and add it if not.
4961 * Removed silc_server_command_join_notify as the function and its
4964 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Changed the client's pending command handling to the same as the
4967 server's pending command handling. It is also now possible to
4968 execute command reply functions from other command reply
4969 function as the function callbacks for commands and command
4970 replies are one and same. The pending commands are not static
4971 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4972 in client connection context. Thus, pending commands are server
4973 connection specific as it is convenient.
4975 Changed the function silc_client_command_pending and
4976 silc_client_command_pending_del and added new function
4977 silc_client_command_pending_check. Removed the
4978 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4981 * Added cmd_ident, current command identifier, to the client
4982 connection context in lib/silcclient/client.h to keep track on
4983 command identifiers used in command sending. Client's command reply
4984 function handling now supports the mandatory command identifiers.
4986 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4987 funtions in client to fully support pending command callbacks.
4989 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4990 as one of the arguments to the application in the command reply
4993 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4994 before first releasing SILC but came back. Now it is removed again
4995 and should come back nomore. The FORWARDED flag was used only
4996 by the JOINing procedure by forwarding the command packet to router.
4997 Now, the JOINing procedure has been changed to more generic (due
4998 to various router environment issues) and FORWARDED is not needed
4999 anymore for anything. The protocol specification is yet to be
5002 Now, removed silc_server_packet_forward from server and the flag
5003 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5005 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Renamed NAMES command to USERS command. The NAMES was named that
5008 due to historical reasons. Now it is renamed. Also, rewrote
5009 parts of the USERS command. The nickname list is not sent anymore
5010 by the server. Only Client ID and mode lists are sent in the USERS
5011 command. Changed this also to the protocol specification.
5013 The client now resolves the names and stuff after it receives
5014 the USERS list from the server when joining to the channel.
5016 * WHOIS and IDENTIFY commands has been changed to support multiple
5017 Client ID's per command. One can now search for multiple users
5018 in the network by sending only one WHOIS or IDENTIFY command.
5019 Changed the code and the protocol specifications.
5021 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5022 uses silc_server_command_whois_parse to parse the request. */
5024 * If normal server, do not parse the WHOIS and IDENTIFY requests
5025 before sending it to the router. Saves some time.
5027 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Fixed JOIN command on client library. Wrong number of arguments
5030 used to crash the client.
5032 * Added silc_server_channel_has_global function to check whether
5033 channel has global users or not.
5035 * Added silc_server_channel_has_local function to check whether channel
5036 has locally connected clients on the channel.
5038 * The silc_server_remove_from_one_channel now checks whether the
5039 channel has global users or not after given client was removed from
5040 the channel. It also checks whether the channel has local clients
5041 on the channel anymore. If it does not have then the channel entry
5042 is removed as it is not needed anymore.
5044 * The silc_server_notify now checks on JOIN notify whether the joining
5045 client is one of locally connected or global. If it is global then
5046 the channel has now global users on the channel and that is marked
5047 to the channel entry. Also, it now saves the global client to
5048 global list who is joining and JOINs it to the channel. This is
5049 for normal server, that is.
5051 Changed silc_server_send_notify_on_channel,
5052 silc_server_packet_relay_to_channel and
5053 silc_server_packet_send_to_channel check if we are normal server
5054 and client has router set (ie. global client) do not send the
5055 message to that client, as it is already routed to our router.
5057 * Implemented LEAVE notify type handling in silc_server_notify
5060 * Tested LEAVE command in router environment successfully. Tested
5061 with two routers, two servers and two clients.
5065 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5067 * Implemented SIGNOFF notify type handling in silc_server_notify
5070 * silc_server_remove_id now removes the client entry from all channels
5071 it has joined and thusly sends SIGNOFF notify type.
5073 * Rewrote the NAMES list generation in server by removing two excess
5074 loops. The lists are created now inside one loop.
5076 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * silc_server_remove_channel_user checks now also global list
5079 for channel and client.
5081 * silc_server_new_channel_user checks now both local and global
5082 list for channel and client. Fixed a bug in client id decoding.
5083 Used to decode wrong buffer.
5085 * silc_server_channel_message checks now both local and global
5086 list for channel entry.
5088 * Tested channel joining (hence JOIN) in router environment
5089 successfully. Tested with two routers, two servers and two
5092 * Tested channel message sending in router environment successfully.
5094 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Added silc_server_save_channel_key into server.[ch] to save the
5097 received channel key in Channel Key payload processing. It is
5098 also used in JOIN command reply handling.
5100 Equivalent function silc_client_save_channel_key added into
5101 client.[ch] into client library.
5103 * Changed JOIN command reply to send information whether the channel
5104 was created or not (is existing already) and the channel key
5105 payload. Changed protocol specs accordingly.
5107 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5108 the request was sent by ID and not by nickname. Crashed on
5111 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5114 now correctly save the received data.
5116 * silc_server_free_sock_user_data now notifies routers in the
5117 network about entities leaving the network.
5119 At the same time implemented functions silc_server_remove_id
5120 and silc_server_send_remove_id to receive and send REMOVE_ID
5121 packets. The packet is used to notify routers in the network
5122 about leaving entities. The ID removed will become invalid in
5125 * Added function silc_idlist_del_server into server. Removes and
5126 free's server entry from ID list.
5128 * silc_server_private_message function now checks, if we are router,
5129 that the destination ID really is valid ID, naturally.
5131 * In router when NEW_ID packet is received (for new client) the
5132 hash of the Client ID is saved in the ID Cache but the
5133 client->nickname is set to NULL, instead of putting the hash
5136 IDENTIFY command now also checks that client->nickname must be
5137 valid. If it is not if will request the data from the server who
5138 owns the client. Added new function
5139 silc_server_command_identify_check.
5141 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5142 to set the command to already allocated Command Payload.
5144 * Tested private message sending in router environment with two
5145 routers, two servers and two clients. Fixed minor bugs and now
5148 * Fixed segfault from client's NAMES command. Used to crash if
5151 * Forwarded packets must not be routed even if it is not destined
5152 to the receiver. Changed server code comply with this.
5154 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Added `require_reverse_mapping' boolean value to ServerParams
5157 structure. If TRUE (not default) the server will require that
5158 the connecting host has fully qualified domain name.
5160 If the reverse mapping is not required and hostname could not be
5161 found the IP address is used as hostname.
5163 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Implemented version string checking to both client and server.
5166 The check is incomplete currently due to the abnormal version
5167 strings used in development version of SILC.
5169 * Changed all command functions in server to use the new
5172 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Changed char *data to unsigned char *data in ID Cache system to
5175 support binary data as ID Cache data. Changed code to support
5176 binary data in lib/silccore/idcache.c.
5178 * Renamed silc_server_packet_relay_command_reply to
5179 silc_server_command_reply as it is normal packet receiving
5180 function. Rewrote the function to accept command replys for
5181 servers and not only for clients.
5183 * Mark remote router always as registered server if we are connecting
5184 to it. Otherwise, commands sent by the router to us are ignored.
5186 * All ID List find routines now returns the ID Cache Entry pointer
5187 as well if requested.
5189 * WHOIS command works now in router environment, tested with two
5190 routers, two servers and two clients.
5192 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5193 in router environment (as it is almost equivalent to WHOIS) but
5194 hasn't been tested thoroughly. Added new functions:
5196 silc_server_command_identify_parse
5197 silc_server_command_identify_send_reply
5198 silc_server_command_identify_from_client
5199 silc_server_command_identify_from_server
5201 * Disabled route cache adding because adding two different ID's with
5202 same IP replaces the old cache entry thus giving wrong route.
5203 The entry->router->connection is always the fastest route anyway
5204 so route cache may not be needed. Of course, new routes maybe
5205 established after receiving the ID when the entry->router->connection
5206 might not be anymore the most optimal.
5208 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Add route cache for received ID for fast routing.
5212 * Added silc_server_packet_route to route received packet on router
5213 that is not destined to us.
5215 * Renamed silc_server_get_route to silc_server_route_get.
5217 * Added id_string and id_string_len fields into SilcServer to
5218 include encoded ServerID for fast comparing without excess
5219 encoding of the ID's.
5221 * Cleaned up WHOIS command on server side. Added following static
5224 silc_server_command_whois_parse
5225 silc_server_command_whois_check
5226 silc_server_command_whois_send_reply
5227 silc_server_command_whois_from_client
5228 silc_server_command_whois_from_server
5230 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5231 arguments in command replies. All command functions should be
5232 updated to use this macro.
5234 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Minor typo fixes on command reply handling on server.
5238 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Added silc_server_command_add_to_channel internal routine to add
5241 the client to the channel after router has created the channel and
5242 sent command reply to the server.
5244 * Added generic silc_server_send_command to send any command from
5247 * Use static buffer with ID rendering instead of duplicating data.
5249 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Fixed a channel user mode bug when joining to a channel server gave
5252 everybody channel founder rights, oops.
5254 * We mark ourselves as the router of the incoming server connection
5255 if we are router ourselves. This way we can check in some packet
5256 sending functions whether it is locally connected server. For
5257 incoming router connections we put NULL.
5259 * For router sending packets locally means now always sending the
5260 packet cell wide; to local clients and local servers. For normal
5261 server sending packet locally means sending it to only local
5264 * Fixed the JOIN command to really work in router environment. If the
5265 channel is created it is always created by the router. Router is
5266 also responsible of making the initial joining to the channel,
5267 sending JOIN notify to the sending server and distributing
5268 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5269 does not exist server doesn't do anything else but forward the
5270 command to the router which performs everything.
5272 * Added silc_server_send_channel_key function to send the Channel Key
5275 * Added silc_server_create_channel_key to create new channel key. The
5276 channel key is now re-generated everytime someone joins or leaves
5277 a channel, as protocol dictates. Note: channel->key_len is the
5280 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5283 packet_receive.[ch] to separate packet sending and receiving
5284 routines. The server.[ch] now includes everything else including
5285 actual packet processing (writing and reading data) and other
5288 Renamed silc_server_private_message_send_internal to
5289 silc_server_send_private_message. The routine is still though
5290 used only to relay private messages as server does not send
5291 private messages itself.
5293 Renamed silc_server_new_channel to silc_server_create_new_channel
5294 and added new function sicl_server_new_channel that handles the
5295 incoming New Channel packet. Added also new sending function
5296 silc_server_send_new_channel to send New Channel Payload.
5298 * Added new function silc_server_notify to process incoming notify
5299 packet to the server/router. Server may then relay the notify
5300 to clients if needed.
5302 * Added new function silc_server_new_channel_user to process incoming
5303 New Channel User packet. Router will redistribute the packet and
5304 send JOIN notify to its local clients and locally connected servers
5305 if needed. Normal server will send JOIN notify to its local client
5306 on same channel when received this packet. Added also corresponding
5307 sending function silc_server_send_new_channel_user to sent the
5310 * Added boolean route argument to send_notif_to_channel and
5311 packet_send_to_channel functions to attempt to route the packet
5312 if it is TRUE and send only locally if it is FALSE.
5314 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * silc_server_replace_id now broadcasts the received replace ID
5317 packet if it is not broadcast packet already. The router must
5318 broadcast to inform other routers about changed ID.
5320 * Added backpointer to server's router into SilcServer context in
5321 silcd/server_internal.h.
5323 * Fixed silc_server_packet_broadcast to send correct broadcast
5326 * The channel key is now distributed to the local client as soon
5327 as it is received from the router (in router environment) so that
5328 no other packet may be sent for the channel until client has
5331 * silc_server_remove_channel_user now broadcasts the received
5332 Remove Channel User packet if it is not broadcast packet already.
5333 The router must broadcast to inform other routers about removed
5336 * Added users field into SilcPacketContext that is a reference count
5337 of the context. One can increase the reference count by calling
5338 silc_packet_context_dup which is now changed to just increase the
5339 reference count instead of duplicating the data. The reference
5340 count is decresed by calling silc_packet_context_free that will
5341 free the data after the reference count hits zero.
5343 For now on the packet context and everything allocated into it
5344 (including the raw packet from network) must be freed by calling
5345 the new silc_packet_context_free function. Added also new function
5346 silc_packet_context_alloc that must be used now to allocate the
5347 context. This also means that if a routine is asynchronous from
5348 silc_[client/server]_packet_parse_type the packet context must
5349 be duplicated by calling silc_packet_context_dup. Otherwise it
5350 gets free'd after silc_[client/server]_packet_parse_type returns.
5351 Also, one must remember that if packet is duplicated then its
5352 reference count must be decresed by calling the free function as
5353 many times as it was duplicated.
5355 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5356 from both client and server.
5358 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Made joining to a channel working in router environment.
5362 * Cleaned up JOIN command on server side and create function
5363 silc_server_command_join_channel internal routine to make the
5366 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Changed silc_command_pending list to SilcDList. Also, added
5369 `ident' field to SilcServerCommandPending structure to identify
5370 the reply and to call correct callback.
5372 Added silc_server_command_pending_check function to replace the
5373 corresnponding macro. The silc_command_pending list is not
5376 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5377 to set identifier to previously allocated Command Payload. It
5378 is used to set identifier for command when resending Command
5381 * Added silc_command_payload_encode_payload to encode Command
5382 Payload buffer from SilcCommandPayload structure.
5384 * Added silc_argument_payload_encode_payload to encode Argument
5385 payload buffer from SilcArgumentPayload structure.
5387 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Changed WHOIS command to support router connection on server side.
5390 The whois request is always sent to router unless the server is
5391 standalone server. After server has received the reply from the
5392 router will it send the reply to the client.
5394 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5395 broadcast received broadcast packet. The function is used only
5396 by router. The broadcast packet is always sent to the router's
5399 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5400 render given ID to printable string, for log files for example.
5402 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Made basic router to router connections working. At least they
5405 can now connect to each other but nothing really works the way
5406 they are supposed - yet.
5408 * Added new initiator token to RouterConnection configuration
5409 file in silcd/serverconfig.[ch]. It is used to tell whether we
5410 are the initiator to the remote router or whether we'll expect
5411 the other end to connect.
5413 * Moved registering of listener task to silc_server_init, hence
5414 the server starts listenning as soon as it is run, even if it
5415 does not have connections to other routers. Let's see how well
5418 * Changed default connection retry timeouts for more suitable in
5421 * Removed cipher and such arguments from silc_idlist_add_client
5422 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5423 Added new function silc_idlist_add_data to add the keys and stuff
5426 * Added SilcIDListData structure and added it to SilcClientEntry
5427 and SilcServerEntry as their first field in the structure. This
5428 way we can explicitly cast the ID entries to the SilcIDListData
5429 structure and get common data for the entries. In past, we had
5430 to first check what type of connection it is and then cast it to
5431 correct ID entry type. Now, we can directly cast the opaque
5432 pointer to the SilcIDListData (no matter what ID entry it actually
5433 is) and get the data needed.
5435 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5438 in some circumstances even if threre were timeout tasks, though not
5439 IO tasks, but tasks anyway. Now fixed.
5441 * Defined SilcServerConnection structure to hold connection specific
5442 stuff about directly connected servers and routers. The definition
5443 is currently in silcd/server_internal.h. I thought about having
5444 a bit more important role fro this struct but for now it is used
5445 only when connecting to other server (or router actually).
5447 * Added connecting retry support in server when connecting to
5448 router(s). The retry feature implement exponential backoff
5449 algorithm. Also, added SilcServerParams structure to hold default
5450 parameters for server. For now, it include these retry settings
5451 and are hard coded. After server is moded to be as Silc Server
5452 Library this structure will be more important.
5454 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Changed client librarys channel->clients table to SilcList and
5457 changed code accordingly.
5459 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Changed client's channel table to SilcList and changed code
5462 accordingly. Also changed SilcChannelClientEntry to include back-
5463 pointer to the channel so that client entry can use that structure
5464 as list as well and we have fast cross-reference to the channel.
5465 This change dramatically decreased the complexity of channel
5466 handling with client entry and vice versa (removed one extra
5467 loop when searching for channel entry from many functions).
5469 * Changed server->sim from table to SilcDList and changed code
5472 * NAMES command can now be used from user interface. It will show
5473 the user list on the channel, neatly.
5475 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5476 Code now saves realname of the user if it becomes available.
5478 * Renamed configure.in to configure.in.pre and made ./prepare
5479 script to automatically add correct version string to
5480 configure.in which it creates from configure.in.pre.
5482 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * NAMES command reply now shows users mode with the nickname when
5487 * Moved silc_client_ch[u]mode[_char] functions from
5488 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5489 place sucks, they are utility functions and should be in some
5492 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5494 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5497 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Added TRQ (efficient deque and list library) into lib/trq. This is
5502 a very good list library that is currently used in the SILC. Defined
5503 SilcList API over the library because I didn't like the API very
5504 much. See lib/trq/silclist.h for the API and examples of how to
5505 use the API. Fixed various places in the code to use the new
5506 SilcList API. The SilcList is meant for lists that has a structure
5507 already defined as a list. It is not suitable to add just some
5508 context to the list (in TRQ, the context is the list actually).
5510 So, I defined SilcDList that can be used for the purpose where
5511 predefined list structure does not exit. This can be used as
5512 such list. Now some context just can be added to the SilcDList.
5513 Currently this list is not used in the SILC just yet, though there
5514 are a lot places where this can replace dynamically allocated
5515 tables and I will fix these places, later, to use SilcDList.
5516 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5517 and use TRQ internally).
5519 Also fixed some annoying warning messages that the original TRQ
5520 code generated. Also minor changes to TRQ's Makefile.in.
5522 * Added support for querying by Client ID to both WHOIS and
5523 IDENTIFY commands into server, as required by the protocol.
5525 * Removed method function pointers from SilcBuffer structure. They
5526 weren't used to anything and just increased the context size for
5527 no good reason. This change also made silc_buffer_alloc and
5528 silc_buffer_free functions inline functions.
5530 * Disabled command flooding detection support until it's fixed so
5531 that it accepts commands in but does not execute them more than once
5534 * Added silc_net_localhost(), to return local hostname, into
5535 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5536 that must be initialized before calling silc_client_init.
5538 * Added new function: silc_server_send_notify_on_channels to send
5539 notify messages to all channels client has joined. It is assured
5540 that the message is sent only once per client.
5542 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5543 lib/silcutil/silcutil.[ch] as silc_format function. The new
5544 function is generic and is used by server as well, not only by
5545 the logging routines.
5547 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5548 the provided version string was not acceptable. Added new function:
5549 silc_ske_check_version into lib/silcske/silcske.h. The function
5550 must be implemented by the application (client or server) and it
5551 does not reside in the SKE library. The function checks the version
5552 string remote end sent.
5554 * Added back pointers (to opaque context and to SilcSocketConnection)
5555 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5557 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5558 duplicate packet context structure.
5560 * Changed `notify' client operation to send same arguments as client
5561 receives from server except for ID's. ID's are mapped to correct
5562 ID entry and that is returned. Also, if channel entry is not sent
5563 by server but the notify is for channel the channel entry is sent
5564 to application (otherwise application doesn't know that it is for
5565 channel (library gets it from packet's Destination ID)).
5567 * Added silc_client_remove_from_channels into client library to
5568 remove a client from all channels it has joined to. Used when
5569 received SIGNOFF notify from server. Added also new function
5570 silc_client_replace_from_channels to replace old ID entry with
5571 new ID entry on all channels. Used when received NICK_CHANGE
5574 * Fixed ID Cache list handling in silc_idlist_get_client in
5575 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5576 to get (or query) client by ID.
5578 * Updated TODO list.
5580 * Added connection authentication status message defined by the
5581 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5582 support for these into the code in client and server side.
5584 * Added generic function silc_client_send_command to send any command
5585 with variable argument list. Application should use this function
5586 to send commands if the command functions provided by the library
5587 does not suite for the application's user interface needs.
5589 * Added new `failure' client operation. Application is notified about
5590 received failure packet if client is executing a protocol. In this
5591 case the protocol's execution has failed.
5593 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5594 is required by the protocol.
5596 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5597 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5600 * Added status flag to SilcSKE object to indicate realtime status
5601 of the SKE protocol.
5603 * Application receives now exactly same command reply arguments as
5604 the library receives from server. However, if ID is received the
5605 corresponding ID entry is returned to the application (eg. Client
5606 ID is mapped to correct SilcClientEntry entry and that is returned).
5607 Changed command_reply client operation due to this change.
5609 * Changed all ID's in commands and in command replys as ID Payloads.
5610 Change affected both client and server side codes.
5612 All ID's sent in SILC network (with execption of ID's in SILC
5613 Packet header) are sent in ID Payload to support variable length
5616 * Server now notifies nick changes and notifies all clients on
5617 the channels about the new nickname (about the new Client ID,
5620 * Implemented CMODE command to change channel modes. Supports all
5621 channel modes defined by the protocol specs except ban and invite
5622 lists. (Also, private channel key mode is supported but support for
5623 setting private channel key in client is missing, thus, this mode
5624 has no effect on client side (except that server requires that the
5625 client uses private channel key and normal channel traffic does not
5628 Also, invite mode works per se, but INVITE command does not work
5629 yet correctly, so you can set channel as invite only channel but
5630 inviting clients to the channel does not work (it is yet to be
5631 thought what's the best way to do it).
5633 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5634 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5635 Implemented CUMODE command to change user's mode on the channel.
5636 Supports all modes defined by the protocol specs.
5638 * Added NAMES command reply to return users modes on the channel.
5640 * Removed unnecessary and slow ciphers from lib/silccrypt.
5642 * Set SO_KEEPALIVE option to connection sockets by default.
5644 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5646 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5647 redefined the Notify Payload into protocol specs.
5649 * Added silc_id_payload_parse_id to get ID directly from raw
5652 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5655 accept searching by Client ID as well.
5657 * Added support for LEAVE and SIGNOFF notify types in client library.
5659 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5660 to parse ID Payload from raw data.
5662 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added flags parameter into silc_ske_assemble_security_properties
5665 function in lib/silcske/silcske.[ch].
5667 * Changed notify client operation to fit better for notify messages
5668 sent by server. The notify payload received from server is now
5669 passed to the application (after parsing it to SilcNotifyPayload).
5670 It is application's responsibility to retrieve the arguments
5671 from the payload and show the message the way it wants. The message
5672 sent by server is implementation specific.
5674 * Changed public keys to comply with the protocol specification.
5675 Old public keys are not supported anymore and are not compatible.
5677 * Removed nickname from Channel Payload as the latest draft removed
5678 it. The client must resolve the nickname from the NAMES command
5679 reply received when it joined the channel.
5681 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5683 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Fixed some errors in protocol specification drafts.
5687 * Created lib/silccore/silcnotify.c to implement Notify Payload
5688 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5689 generic payloads described by protocol specifications. The file
5690 includes implementations for ID Payload and Argument Payload.
5692 * Changed Command Payload implementation to use the new Argument
5693 Payload. Changed command_xxxx_payload to command_payload_xxxx
5694 to comply with SILC coding conventions.
5696 * Added suppport for Argument Payload handling in Notify Payload
5697 implementation as protocol requires it. Added the new support
5698 into server and client lib as well.
5700 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Added support for multiple nicknames on same channel. [n] is
5703 added locally to the nickname if there are more than one same
5704 nicknames on the channel.
5706 * Server now sends all nicknames that matched WHOIS request.
5707 Client also shows the list received from server.
5709 * Added TOPIC command to client side. User can now set and show
5710 current topic on channel.
5712 * Added MOTD command to client and server. Also, server sends the
5713 motd when client connects to the server.
5715 * Changed version strings to comply ISO 8601.
5717 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Fixed protocol error handling in client library. It should now
5720 cope even if the SKE fails for some reason.
5722 * Made new protocol specification drafts for submitting to IETF.
5724 * Implemented TOPIC command to server in silcd/command.c.
5726 * Added two new notify types into lib/silccore/silcnotify.h:
5727 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5728 notify nickname change and topic setting/change on a channel.
5730 * API change of command_reply operation in client library. The
5731 application gets now the status type received from server as well.
5733 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5737 * Cras fixed and optimized the packet handling even further and
5738 it should work now. Minor change to the prototype of function
5739 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5741 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added new function into lib/silcutil/silcschedule.[ch]:
5744 silc_schedule_with_fd to select() a specified fd. The function
5745 returns after timeout expires or data arrives or goes. The
5746 function is used by packet routines to wait that all data is
5747 received from network.
5749 * Fixed data reading from network in lib/silccore/silcpacket.c.
5750 The code now assures that all data is read from the fd and then
5751 continues packet processing. This was a bug fix since the code
5752 used to drop some data in some circumstances.
5754 * Added new function into lib/silcclient/client.[ch]:
5755 silc_client_start_key_exchange to start key exchange after
5756 connection has been established to server. The code internally
5757 now uses this funtion but its main purpose was to provide it
5758 for applications that perform their own connecting. After
5759 application has created a connection it merely calls this
5760 function to start the key exchange between client and server.
5761 The library takes care of everything else after that.
5763 Updated also lib/silcclient/README to explain the usage of
5766 * Do not send to application information that connection has
5767 been established. Application gets notified it by connect
5770 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Applied cras's patch to add silc_schedule_one function. The
5773 function runs scheduler once and returns.
5775 * Fixed the scheduler after cras messed it up. The timeout
5776 handling works now as it's supposed to work.
5778 * Added into lib/silccore/ silcnotify.h to include notify
5779 message types support. Changed silc_server_send_notify*
5780 functions, in server.[ch], to support those new notify types.
5781 Added the support for the notify types into client library,
5782 as well. Added new notify client operation into ops.h in
5785 * Changed silc_server_packet_send_to_channel to send normal
5786 packets instead of just channel message packets. The function
5787 is now used to send the notify packets to channels. It is not
5788 used to send channel message packets anymore, as server never
5791 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5792 va_arg()s as it seems to require it nowadays. I guess, if SILC
5793 is compiled with older va_arg() the new code should work anyway.
5795 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Splitted core library. Core library (lib/silccore) includes
5798 now only SILC protocol specific core (and common) components.
5799 Created new utility library (lib/silcutil) that includes more
5800 generic purpose stuff. The stuff for util library was taken
5801 from the old core library. This was minor and easy split.
5803 * Created SILC Client Library (lib/silcclient) that includes
5804 implementation of the SILC client without user interface. This
5805 was major move from silc/ directory. The code has been changed
5806 so that it is transparent towards the user interface. The
5807 silc/ directory includes now the same user interface as before
5808 and it uses the new client library. Read lib/silcclient/README.
5809 Basicly, the client library performs everything else related
5810 to SILC except user interface handling. Also, configuration
5811 files are considered to be part of user interface and library
5812 does not handle them.
5814 This change also changed a lot of structures, function naming etc.
5815 Most important change was that SilcClientWindow object was
5816 renamed to SilcClientConnection in the client library. Created
5817 also new file lib/silcclient/ops.h. Also added new files
5818 silc/local_command.[ch] and silc/client_ops.[ch].
5820 All these changes were made to make it easier for user interface
5821 designers to create what ever user interface for the SILC client
5824 It is also expected that the server will be moved to lib
5825 directory as well and SILC Server Library will be created;
5826 sometimes in the future.
5828 * Removed Local commands from lib/silccore/silccommand.h as
5829 they are application specific and new client library does not
5830 handle any of those anymore.
5832 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5833 old client implementation in silc/.
5835 * Added support for callback functions in SILC_LOG_* macros.
5836 Application can now set its own callbacks that will be called
5837 instead of using the default functions that will always print
5838 the debug messages to stderr (or stdout). Also, debugging can
5839 now be disabled by setting silc_debug to FALSE and re-enabled by
5840 setting it to TRUE. Note, that logging will still work even
5841 if debugging is disabled.
5843 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5844 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5845 silc_log_reset_debug_callbacks.
5847 * To enable debugging in silc client one must give now -d
5848 option on command line.
5850 * Changed silc_schedule_init to automatically allocate task queues
5851 if they are not allocated before calling it.
5853 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Added GMP 3.1 into math library.
5857 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5859 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5860 a channel in SILC network. The packet is used by servers and
5861 routers to notify other routers that user has left a channel.
5862 This little feature was missing until now. Added the feature
5863 to protocol specification as well.
5865 Added functions: silc_server_send_remove_channel_user and
5866 silc_server_remove_channel_user into server.[ch].
5868 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5869 lib/silccore/silcpacket.h. However, they are not implemented
5872 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5874 * Fixed joining to a channel and sending channel messages
5875 between server and router. The channel message sending should
5876 now work inside a cell.
5878 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Fixed the private message sending between server and router.
5881 The private message sending should now work inside a cell.
5883 * Added silc_server_replace_id into server.[ch] to replace
5884 existing ID in the SILC network.
5886 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5887 and silc_idlist_replace_server_id into idlist.[ch] in server.
5889 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Fixed the server to server connections. Server can again now
5892 connect to router. Router to router connections probably does
5895 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Added dynamic protocol registering support. Now protocols can
5898 registered and unregistered on the fly. Patch by cras.
5900 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Added lib/contrib directory to hold routines that some platforms
5903 don't have but are needed by SILC.
5905 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5906 into lin/contrib to provide getopt() and getopt_long() for
5907 those who don't have it.
5909 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Added AWAY command to client. When away message is set and
5912 client receives a private message packet the client automatically
5913 replies to the sender with the away message.
5915 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5916 bug seemed to be the cause of recent problems when compiling
5919 * Added version detection support to SKE protocol specification
5920 and added the new changes to the SKE implementation as well.
5921 There were other minor changes in the SKE protocol as well.
5923 Many changes in lib/silcske/silcske.[ch] and in
5924 lib/silcske/payload.[ch].
5926 * Added ^U functionality, clear input line. Patch from cras.
5928 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Mainly small bugfixes on core library. Fixed some debugging
5931 logging and buffer overflow in silclog.c.
5933 * Updated config.sub and config.guess on the distribution tree.
5935 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Added command lagging support in server. Client may execute
5938 commands now only once in two seconds.
5940 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Optimized packet reception. MAC computation and checking is now
5943 also more optimized. A lot previously duplicated code is now
5944 used as generic by both client and server.
5946 * Fixed key pair generation in clientutil.c
5948 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Added into lib/silccore/silcbufutil.[ch] new function;
5951 silc_buffer_realloc.
5953 * Moved generic packet sending/encryption functions to
5954 lib/silccore/silcpacket.[ch] from client and server. Some
5955 rewriting of the functions.
5957 * Moved all generic packet reception/decryption functions to
5958 lib/silccore/silcpacket.[ch] from client and server. The
5959 packet processing is now much cleaner in both client and server.
5960 These were major changes in both client and server.
5962 * Created many common functions in server to do packet sending.
5963 Previously code were duplicated a lot, this has been removed
5966 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Rewrote major parts of the ID cache system. Don't know
5969 whether it is better now or not but at least the API is more
5972 * Major rewrite on ID cache stuff on client because of the ID
5973 cache API changes. Added idlist.c to client.
5975 * Also major rewrite on ID cache stuff on server as well.
5976 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5977 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5978 in hand, instead they are all put into the ID cache system now.
5979 All server_idlist_* routines uses ID cache now instead of
5980 traversing its own lists (those lists does not exist anymore).
5981 SilcIDList though still exists. Also, SilcXXXEntry's are
5984 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Finally made the SKE implementation compliant to the protocol
5987 specification. All mp integers are now binary encoded as
5988 opposed being HEX encoded.
5990 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5993 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5994 functions: silc_[encode/decode]_pem. Also added function
5995 silc_encode_pem_file to PEM encode with newlines ('\n') for
5998 * SILC public keys are now encoded either PEM or binary. Same
5999 option is for private keys as well. By default private keys
6000 are binary encoded and public keys PEM encoded. Silly HEX
6001 encoding were removed.
6003 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6004 function to create fingerprints.
6006 * Fixed a bug in SHA1; does not change the original data anymore.
6008 * Partly implemented INFO command on client and server side.
6009 Fixed CLEAR command. Changes to SERVER command; show current
6010 server(s) when giving command without arguments. Added
6011 VERSION command to client.
6013 * Added check to server that unregistered connections cannot
6014 execute commands (unless it is specificly allowed).
6016 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * Fixed screen refresh.
6020 * Fixed channel joining bug from client. On some circumstances
6021 client tried to join to a channel it had already joined.
6023 * Added public key verification process into client's protocol.c.
6024 The client now verifies the public key from user and saves
6025 it into ~./silc/serverkeys/ directory.
6027 Added into: clientutil.[ch]: silc_client_verify_server_key.
6029 * Changed SKE protocol's silc_ske_initiator_finish function
6030 to accept callback function that verifies the received public
6031 key. Removed old silc_ske_verify_public_key function.
6033 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6036 silc_pkcs_private_key[_data]_set.
6038 * Made the password and public authentication more cleaner in
6039 server's protocol.c.
6041 * Removed historic and obsolete protocol `channel_auth' from
6042 both client and server.
6044 * Removed wrong way of sending command status messages from
6045 server to client in server's command.c. The old way violated
6046 protocol specification.
6048 Changes to silccore/silccommand.[ch]: removed
6049 silc_command_encode_status_payload -> not needed anymore,
6050 changed silc_command_encode_payload_va to accept extra
6051 argument on variable argument list. The argument type must
6052 now be provided to the function. Also, added new function:
6053 silc_command_encode_reply_payload_va which is same as
6054 normal command_encode_payload_va except command status type
6055 is provided as extra argument.
6057 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added ~./silc directory handling. The directory includes the
6060 public and private keys for the client.
6062 Added silc_client_check_silc_dir, silc_client_create_identifier
6063 and silc_client_load_keys.
6065 * Implemented SILC protocol compliant public key. Added public
6066 and private key saving to and loading from files.
6068 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6069 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6070 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6071 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6072 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6074 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6075 silc_pkcs_load_[public/private]_key.
6077 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Added silc_server_get_route (route.[ch]) to get connection
6080 data for the fastest route for given ID.
6082 * Implemented INVITE command on client and server. The command
6083 were re-defined in the SILC Protocol Specification and the
6084 implementation now complies with the specification.
6086 * Implemented PING command on client and server.
6088 * Implemented NAMES command on client and server. The server side
6089 supports currently only normal server not router server yet.
6090 Some changes to NAMES definition in SILC protocol specification.
6092 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Implemented LEAVE command on client and server.
6096 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6097 again. This change was made to the protocol as well. Server
6098 should not violate the protocol specification anymore.
6100 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6103 was tested. SOCKS4 was not but should work anyway.
