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

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

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

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

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

455 irssi/src/silc/core/client_ops.c,
456 irssi/src/silc/core/silc-server.[ch].
458 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
460 * Relay the SILC_PACKET_FTP in the server. Affected files
461 silcd/server.c and silcd/packet_receive.c.
463 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Renamed silc_file_read and silc_file_write to functions
466 silc_file_readfile and silc_file_writefile. Added function
467 silc_file_open and silc_file_close. Affected files
468 lib/silcutil/silcutil.[ch].
470 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Resolve the client info when received private message or
473 channel message for a client which nickname we don't know.
474 Affected files lib/silcclient/client_prvmsg.c and
475 lib/silcclient/client_channel.c.
477 * Do not crash in /KEY if client is not connected. Affected
478 file irssi/src/silc/core/silc-channels.c.
480 * Added SilcClientStatus field to the SilcClientEntry in the
481 lib/silcclient/idlist.h.
483 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
484 is incomplete and is being resolved, it won't be resolved
487 Make sure also that USERS command reply does not resolve
488 twice information. Affected file is
489 lib/silcclient/command_reply.c.
491 Make sure that silc_client_get_clients_by_list does not
492 resolve twice same information.
494 * Check for valid client->id in the silc_server_free_client_data.
495 Affected file silcd/server.c.
497 * Fixed /GETKEY nick@server not to crash if the server entry
498 is not found. Affected file lib/silcclient/command.c.
500 * Fixed the silc_server_check_cmode_rights to check the
501 requested modes correctly. Affected file silcd/command.c.
503 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Better checks for non-printable chars in nick added.
506 Affected file silcd/command.c.
508 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Call the silc_server_udpate_servers_by_server in the
511 primary router that comes back online in the backup resuming
512 protocol. Otherwise it routes packets wrong. Affected file
513 silcd/server_util.[ch], silcd/server_backup.c.
515 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
518 lib/silcutil/silcbuffmt.[ch].
520 * Redefined the SILC packet header to include the padding
521 length. Affected file lib/silccore/silcpacket.[ch].
523 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
524 length for maximum padding up to 128 bytes). Affected
525 file lib/silccore/silcpacket.h.
527 * Removed all backwards support for old 0.5.x MAC thingies.
528 The SILC packet header change makes it impossible to be
529 backwards compatible.
531 * Send the ENDING packet with timeout in the backup resuming
532 protocol. This is to assure that all routers has connected
533 to the primary router. Affected file silcd/server_backup.c.
535 * Changed the RNG to take the first IV from random data. It
536 used to take it from zero actually. Changed the RNG also
537 to use /dev/urandom during session. /dev/random is used
538 in initialization. Affected file lib/silccrypt/silcrng.[ch].
540 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Changed the SILC packet header to have the first two bytes
543 (the packet length) encrypted. Affected files aroung the
544 code tree, lib/silccore/silcpacket.[ch]. Removed the
545 SilcPacketCheckDecrypt callback. It is not needed anymore
546 since the silc_packet_receive_process will determine now
547 whether the packet is normal or special.
549 * Implemented the unidirectional MAC keys. Affected files
550 lib/silcske/silcske.c, silcd/protocol.c and
551 lib/silcclient/protocol.c.
553 * Implemented the packet sequence number to the MAC computation.
554 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
555 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
556 lib/silcclient/protocol.c.

560 * Allow backup router to announce servers. All servers
561 announced by backup router are added to the global list
562 automatically. Update hte server's socket to our primary
563 router also when backup router announces a server.
564 Affected file silcd/packet_receive.c.
566 * Do not update the client->router in the function
567 silc_server_udpate_clients_by_server if the client is on
568 global list. We might fail to find any specific server
569 for locally connected clients and local cell clients. They
570 should still use the `from' and not `to' as client->router.
571 This fixes backup router resuming protocol. Affected file
574 * Decrease channel statistics count only if the channel
575 deletion worked. Affected files are silcd/server.c and
578 * Added silc_server_update_servers_by_server to update origin
579 of all server entries. Used during backup router protocol.
580 Affected files silcd/server_util.[ch], silcd/server.c. and
581 silcd/backup_router.c.
583 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
584 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
585 silc_hmac_get_hash and silc_hmac_get_name. Affected file
586 lib/silccrypt/silchmac.c.
588 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
590 * Assure that router cannot reroute the same channel message
591 to the sender. Affected file silcd/packet_receive.c.
593 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
595 * Made better checks that the channel message is not sent
596 to the router it came from. Affected file is
597 silcd/packet_send.c. Fixed memory leak too.
599 * Announce informations for incoming router connection, but
600 only after checking if it is replaced by backup router.
601 Affected file silcd/packet_receive.c.
603 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
605 * Fixed the backup resuming protocol to work in multiple
606 router environment. Affected file silcd/server_backup.c.
608 * Route packet only to one router in the function
609 silc_server_packet_send_to_channel. Affected file is
612 * Fixed silc_server_send_notify_dest to set the broadcast
613 flag. Fixed the silc_server_send_notify_topic to actually
614 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
615 Affected file silcd/packet_send.c.
617 * Changed the SFTP Filesystem interface. Changed the
618 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
619 the filesystem operation function. The SilcSFTPFilesystem
620 is now a context that is allocated by all filesystem allocation
621 functions and it already includes the operations structure
622 and filesystem specific context. It is given as argument
623 now to the silc_sftp_server_start. This made the interface
624 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
625 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
627 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Changed the backup router adding and getting interfaces
630 in the server. The router that will be replaced by the
631 specified backup router is now sent as argument. Affected
632 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
635 * Added silc_net_addr2bin_ne to return the binary form of
636 the IP address in network byte order. Affected files
637 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
639 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
641 * Check for existing server ID in silc_server_new_server
642 and in silc_server_connect_to_router_final and remove the
643 old entry if it exists. Affected file silcd/packet_receive.c,
646 * Send the channel message always to only one router, either
647 in upstream or downstream. Affected file is
650 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
652 * Wrote the definition of the backup resuming protocol to the
653 protocol specification.
655 * Removed one redundant channel key generation from normal
656 server during joining procedure. Removed one redundant
657 channel key sending from server to router during joining
658 procedure. Affected file silcd/command.c.
660 * Made minor bugfixes to the backup router resuming protocol.
661 Affected file silcd/server_backup.c, server.c.
663 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Added --disable-asm configuration option. Affected files
666 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
669 * Implemented the backup resuming protocol that is used to
670 resume the primary router position in the cell after the
671 primary router comes back online. Affected files
672 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
673 and silcd/server_util.[ch].
675 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
677 * Sleep two (2) seconds after sending QUIT command to server.
678 Affected file lib/silcclient/command.c.
680 * Assure that if outgoing data buffer is pending do not force
681 send any data. Affected file silcd/packet_send.c.
683 * Assure that if outgoing data buffer is pending do not force
684 send any data. Affected file lib/silcclient/client.c.
686 * Implemented the backup router support when the primary router
687 goes down. The servers and routers can now use the backup
688 router as new primary router without loosing connectivity.
690 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
693 in the server to indicate disabled entry. All data read
694 from the connection will be ignored and no data is sent
695 for entry that is disabled. Affected files are
696 silcd/idlist.h, silcd/server.c.
698 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Created SFTP client and server test programs in the
701 lib/silcsftp/tests directory.
703 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
705 * Implemented memory filesystem (virtual filesystem) for
706 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
709 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
711 * Implemented the SFTP (SSH File Transfer Protocol) to the
712 lib/silcsftp. It includes SFTP client and SFTP server
715 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
717 * Moved lib/silccore/silcprotocol.[ch] to the
718 lib/silcutil library.
720 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
721 take variable argument list pointer as argument. Affected
722 file lib/silcutil/silcbuffmt.[ch].
724 * Added silc_buffer_set function that is used to set data
725 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
726 Affected file lib/silcutil/silcbuffer.h.
728 * Changed various routines in the core library to use the new
729 silc_buffer_set instead of allocating new buffer only for
732 * Added 64-bit value formatting and unformatting support to the
733 silc_buffer_[un]format routines. Affected file is
734 lib/silcutil/silcbuffmt.[ch].
736 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
737 to includes/bitmove.h.
739 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Fixed channel user mode saving in client library. Affected
742 file lib/silcclient/command[_reply].c.
744 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Defined the file transfer to the SILC Protocol. Added
747 new packet type SILC_PACKET_FTP and defined File Transfer
748 Payload. The mandatory file transfer protocol is SFTP
749 (SSH File Transfer Protocol). Affected file in addition
750 of the internet draft is lib/silccore/silcpacket.h.
752 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
753 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
754 is used as part of backup router protocol when the primary
755 router of the cell is back online and wishes to resume
756 the position as primary router.
758 * Redefined the MAC generation keys in the protocol. The
759 same key is not used anymore in both direction. Both
760 direction will now use different keys for sending and
761 receiving. This fixes a potential security flaw. This
762 change causes incompatibilities in the protocol.
764 * Redefined also the MAC computation from the packet.
765 An packet sequence number is now added to the MAC
766 computation. This prevents possible replay attacks against
767 the protocol. This change too causes incompatibilities
770 Added `sequence' field to the SilcPacketContext to hold
771 the current sequence number for the packet.
773 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Added `created' field to the SilcIDListData in the file
776 silcd/idlist.h to indicate the time when the entry was
779 * Added `created' field to the SilcChannelEntry too. Affected
782 * Added `creation_time' aguments to all the announcement functions
783 in the server. If it is provided then only the entries that
784 was created after the provided time frame are actually
785 announced. Affected file silcd/server.[ch].
787 * The protocol says that the Channel ID's IP address must be
788 based on the router's IP address. Added check for this in
789 the silc_server_new_channel when processing incoming New Channel
790 Payload. Affected file silcd/packet_receive.c.
792 * Print out the correct version with --version in SILC client.
793 Affected file irssi/src/silc/core/silc-core.c.
795 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
797 * Fixed WHOWAS command to check for completnes of the client
798 entry always, not just when the command is coming from client.
799 Affected file silcd/command.c.
801 * Added new function silc_server_packet_queue_purge to purge the
802 outgoing data queue to the network. After the function returns
803 it is guaranteed that the outgoing packet queue is empty.
804 Affected file silcd/packet_send.[ch].
806 * Purge the outgoing packet queue in the rekey protocol's final
807 callback to assure that all rekey packets go to the network
808 before quitting the protocol. Affected file silcd/server.c.
810 * Added silc_client_packet_queue_parse as similar function as
811 in server to the client library. The affected file is
812 lib/silcclient/client.c.
814 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Splitted silcd/server.c and created silcd/server_util.[ch]
817 for utility functions.
819 * Added new socket flag SILC_SF_DISABLED to indicate that the
820 connection is open but nothing can be sent to or received from
821 the connection. Affected file lib/silcutil/silsockconn.[ch].
822 The checking for disabled socket is checked in the low level
823 silc_socket_write and silc_socket_read functions.
825 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Allow only nicknames and channel names that fits into the
828 7-bit unsigned char ASCII set. Affected file silcd/command.c.
830 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
832 * When processing JOIN command reply in server check that if
833 the channel exists in our global list we'll move it the local
834 list. Affected file silcd/command_reply.c.
836 * Fixed the check whether client is joined on the channel already
837 in JOIN command. Affected file lib/silcclient/command.c.
839 * Fixed the JOIN command reply to check whether the channel
840 already exists. Affected file lib/silcclient/command_reply.c.
842 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
844 * Added silc_ske_status_string to map the SKE error numbers
845 to readable strings. The affected files are
846 lib/silcske/silcske[_status].[ch].
848 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Do not show the private channels on the WHOIS channel list
851 as it is not allowed by the protocol. The affected file is
854 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Assure that the packet length digged from the actual packet
857 is something sensible in the silc_packet_decrypt_rest_special
858 in lib/silccrypt/silcpacket.c.
860 * Free and NULL the allocated pointer in silc_hmac_alloc if
861 the HMAC allocation fails. The affected file is
862 lib/silccrypt/silchmac.c.
864 * Print the selected security properties to the log files in
865 the server. Affected file silcd/protocol.c.
867 * Add SKE's reference counter even if calling the completion
868 callback manually. Otherwise it goes negative, although it
869 does not cause any problems. The affected file is
870 lib/silcske/silcske.c.
872 * Remove the client entry with short timeout after giving the
873 KILL command. Affected file lib/silcclient/command.c.
875 * Fixed to send error reply in WHOIS and IDENTIFY commands in
876 case all found clients are already disconnected (WHOWAS would
877 found them) in the server. Affected file silcd/command.c.
879 * Update the last_receive (time of last data received) to be
880 updated only when received private or channel message so that
881 the idle time showed in WHOIS makes more sense.
883 * Added boolean field `valid' in to the SilcClientEntry in the
884 client library to indicate whether the entry is valid or not.
885 This fixes the nickname change bug on channel when changing
886 the nickname to be same than the old (like nick to Nick) the
887 nickname formatter doesn't set the new nick anymore to Nick@host.
888 Affected file lib/silcclient/idlist.[ch].
890 * Now actually fixed the nickname changing on disconnection.
891 Added new function silc_change_nick to the Irssi SILC Client.
892 Affected file irssi/src/silc/core/client_ops.c,
893 irssi/src/silc/core/silc-nicklist.[ch].
895 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Check that the public key exists in the GETKEY command before
898 trying to encode it. Affected file silcd/command.c.
900 * Print some notifications on received public keys with GETKEY
901 command in the Irssi SILC Client. Affected files are
902 irssi/src/fe-common/silc/module-formats.[ch],
903 irssi/src/silc/core/client_ops.c.
905 * Use IDENTIFY command to resolve the server information in the
906 GETKEY command instead of INFO command. Affected file
907 lib/silcclient/command.c.
909 * All command reply functions in the client library now calls
910 the pending command reply callbacks even if an error has
911 occurred. The server has done this a long time and now it was
912 time to move the client library to this as well. Now all
913 errors can be delivered back to the pending command reply
914 callbacks if necessary. Affected files are
915 lib/silcclient/command[_reply].[ch].
917 * Change the nickname on disconnection back to the username
918 because in reconnect the server will enforce it to it anyway.
919 Affected file irssi/src/silc/core/silc-servers.c.
921 * Fixed a config file parsing bug in the Irssi SILC client.
922 Affected file irssi/src/silc/core/clientconfig.c.
924 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
926 * When printing the channel mode on JOIN, verify that the
927 channel key and channel's HMAC are valid. Affected file
928 irssi/src/silc/core/client_ops.c.
930 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
933 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
934 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
936 * Removed channel key rekey task deleting from the function
937 silc_server_save_channel_key. Affected file silcd/server.c.
938 Added explicit timeout task context instead that is used to
939 delete the task if we are registering a new task before the
940 new task has elapsed.
942 * When channel key rekey occurs the client library now saves
943 the old channel key for a short period of time (10 seconds) and
944 is able to use it in case some is still sending channel
945 messages encrypted with the old key after the rekey. Affected
946 file lib/silcclient/[idlist.h|client_channel.c].
948 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Added check to the silc_server_new_id_real to not accept
951 new ID if it is the sender's own ID. Affected file is
952 silcd/packet_receive.c.
954 * Assure that we do not announce ourself or the one we've
955 sending our announcements when we're router and are announcing
956 servers to our primary router. Affected file silcd/server.c.
958 * Fixed silc_server_command_identify_check_client to assemble
959 correct WHOIS packet. It send corrupted WHOIS packet and
960 caused problem with router to router connections. Affected
961 file silcd/command.c.
963 Fixed also silc_server_command_whois_check the same way
964 as for the IDENTIFY command.
966 * Added new SilcIDListStatus to the server in the SilcIDListData
967 structure. The status now includes the current status of
968 the entry (like registered, resolved etc.). Affected file
969 silcd/idlist.[ch]. Defined a bunch of different status types
970 as well. This replaced the old boolean registered field as well.
972 Added resolve_cmd_ident field to the SilcClientEntry structure
973 too so that if the entry is for example being resolved so
974 another command may attach to the same pending command reply
975 without requiring to resolve the same entry again. This concept
976 should optimize the WHOIS and the IDENTIFY resolving under
977 heavy load by taking away unnecessary resolving for entries
978 that are being resolved already.
980 Added support for adding multiple pending commands for one
981 command idenfier. Affected file silcd/command[_reply].[ch].
983 * Fixed WHOIS and IDENTIFY save to remove the cache entry
984 before deleting the data. Otherwise the hash table will have
985 freed data in comparison functions. Affected file is
986 silcd/command_reply.c.
988 * Fixed silc_idlist_replace_client_id to add the new entry to
989 the cache with NULL nickname. Otherwise there will be invalid
990 memory as the nickname after the nickname is freed. Affected
991 file silcd/packet_receive.c.
993 * Fixed the silc_idlist_get_clients_by_hash. The entries was
994 saved into wrong slots because the previous number of entries
995 was not taken into account. Affected file silcd/idlist.c.
996 Fixed same thing in silc_idlist_get_clients_by_nickname too.
998 * If we are router and we receive JOIN notify to a channel that
999 does not have any users then notified client is marked as the
1000 channel founder, as it is it. The affected file is
1001 silcd/packet_receive.c
1003 * Added to the extended hash table API's table_del_*ext functions
1004 the destructor as argument too, so that the caller can decide
1005 which destructor to use or whether to use destructor at all.
1006 Affected file lib/silcutil/silchashtable.[ch].
1008 * Fixed ID Cache purging. It actually deleted the entries from
1009 the hash table after the data was freed. The hash table ended
1010 up comparing freed memory. The affected file is
1011 lib/silccore/silcidcache.c.
1013 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Fixed Irssi SILC client's KILL command's HELP syntax.
1017 * The USERS command now resolves the detailed user information
1018 if the userinfo field is missing. Affected file is
1019 lib/silcclient/command_reply.c.
1021 * Do not print error in silc_file_read if the read file does
1022 not exist. Just silently return NULL. Affected file is
1023 lib/silcutil/silcutil.c.
1025 * Fixed the silc_log_output to not wine about NULL filename
1026 and to not create some bogus " " filename. Affected file is
1027 lib/silcutil/silclog.c.
1029 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Fixed various printing bugs on the user interface in the
1032 Irssi SILC Client. Minor changes that were forgotten from
1035 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Fixed the configure.in.pre and the compilation and distribution
1038 environment to support the new autoconf 2.52. That version is
1039 now required to compile the CVS trunk.
1041 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1044 to generally parse user@fqdn format strings. Affected file
1045 lib/silcutil/silcutil.c.
1047 * Added nickname_format and nickname_force_format fields to the
1048 SilcClientParams structure. The first one defines the format
1049 for the nicknames that the library will enforce if the receives
1050 multiple same nicknames. The second one is boolean value and
1051 can be used to force the library to always enforce the format
1052 to the nicknames regardles whether there are multiple nicknames
1053 or not. This configurable formatting was employed to flexibly
1054 support accessing multiple nicknames from the user interface.
1055 The userinterface can now set the nicknames to what ever format
1056 they prefer. Affected file lib/silcclient/silcapi.h.
1058 Added function silc_client_nickname_format to the file
1059 lib/silcclient/idlist.c. It performs the nickname formatting.
1061 Added new field `hostname´ to the SilcClientEntry context.
1062 It holds the hostname of the client. Affected file is
1063 lib/silcclient/idlist.h.
1065 * Irssi SILC Client sets the nicknames in nick@hostn format.
1066 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1067 irssi/src/silc/core/silc-core.c.
1069 The WHOIS printing now also shows both the real nickname and
1070 the formatted nickname so that user knows how to access the
1071 user if there are multiple same nicknames cached. Affected
1072 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1073 printing formatting too to take the hostname now as a separate
1074 argument. The Affected file is
1075 irssi/src/fe-common/silc/modules-formats.[ch].
1077 * Changed the silc_client_get_clients_local to accept the formatted
1078 nickname as argument. It accepts the real nickname too but the
1079 formatted nickname can be used to find the true entry from
1080 multiple entries. Affected file lib/silcclient/silcapi.h and
1081 lib/silcclient/idlist.c.
1083 * Added nickname_format_parse field to the SilcClientParams.
1084 It is a callback function provided by the application to parse
1085 the nickname out of the formatted nickname string. The library
1086 calls it to get the nickname from the formatted string. Since
1087 the application generally knows better the format of the nickname
1088 string it parses it instead of the library, even though library
1089 encodes the formatted string. If the callback function is not
1090 provided then the library will use the string as is. The
1091 affected file is lib/silcclient/silcapi.h.
1093 * All the nickname strings passed to the client library in
1094 commands are now expected to be formatted nickname strings.
1095 If the command does not support the formatted nickname string
1096 it will assume that the sent string is the actual nickname.
1097 Affected file lib/silcclient/command.c.
1099 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Added public key authentication support to OPER and SILCOPER
1102 commands in the client library. Affected file is
1103 lib/silcclient/command.c.
1105 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Changed the get_auth_methdod client operation to be asynchronous.
1108 It can be async if the application resolves the authentication
1109 method from the server during the negotiation. Added new
1110 SilcGetAuthMeth completion callback that the application will
1111 call after resolving the authentication method.
1113 Added function silc_client_request_authentication_method that
1114 the application can use to resolve the authentication method
1115 from the server. Added also SilcConnectionAuthRequest callback
1116 that the library will call after the server has replied. The
1117 application can call this function if it does not know the
1118 current authentication method.
1120 Affected files are lib/silcclient/client.c and
1121 lib/silcclient/silcapi.h.
1123 * The Irssi SILC client now automatically resolves the authentication
1124 method incase any configuration information is not present (and
1125 currently there never is). The affected file is
1126 irssi/src/silc/core/client_ops.c.
1128 * Fixed public key authentication from the client library.
1129 Affected file lib/silcclient/protocol.c. Changed also the
1130 protocol specification about the public key authentication in
1131 the connection authentication protocol. The actual data to be
1132 signed is now computed with a hash function before signing.
1134 * Fixed the public key authentication from the server as well.
1135 Affected file silcd/protocol.c.
1137 * Removed the mlock()'s from the memory allocation routines.
1138 Affected file lib/silcutil/silcmemory.c. The ./configure does
1139 not check anymore for the mlock(). Affected file is
1142 * Fixed USERS command in server to allow the execution of the
1143 command for private and secret channels if the client sending
1144 the command is on the channel. Affected file silcd/command.c.
1146 * Fixed silc_client_get_clients_local to return the clients
1147 count correctly. It could return wrong value. Affected file
1148 lib/silcclient/idlist.c.
1150 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1153 types. The assembler optimizations seemed not to like 64-bit
1154 data types. The assmebler optimizations thus are now enabled
1155 also for BSD systems as opposed to only enable them for Linux.
1157 * Do not check for threads at all on BSD systems. Affected
1158 file configure.in.pre.
1160 * Removed -n and -h options from the Irssi SILC Client since
1161 they are not used in silc.
1163 * Fixed the prime generation to assure that the first digit
1164 of the generated random number is not zero since our conversion
1165 routines does not like number strings that starts with zero
1166 digit. If zero digit is seen the random number is regenerated.
1167 This caused some corrupted RSA keys when the zero first digit
1168 was met. Affected file lib/silcmath/silcprimegen.c.
1170 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Fixed WIN32 configuration in the ./configure script.
1173 Fixed to include xti.h on environments that has it.
1174 Patches by Carsten Ilchmann and andrew.
1176 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Changed the silc_id_create_client_id to be collision
1179 resistant. It is now assured that there cannot be created
1180 two same client ID's. I suspect that some weird bugs in
1181 the server were actually caused by duplicate Client IDs.
1182 Affected file silcd/serverid.[ch]. A router receiving
1183 new ID now also assures and informs the sending server
1184 if the ID caused collision.
1186 * Changed the silc_id_create_channel_id to also assure that
1187 there are no collisions.
1189 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Statement about ignoring the Mutual Authentication flag when
1192 performing rekey with PFS was a bit misleading. It is ignored
1193 if it was set in the initial negotiation, it cannot be even
1194 set in the rekey. Fixed in the ke-auth draft. Started the
1195 new versions of the protocol drafts in the doc/.
1197 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Fixed a bug in silc_client_command_identify_save when saving
1200 new channel information. The channel name was no duplicated
1201 and caused crash on exit. Affected file is
1202 lib/silcclient/command_reply.c.
1204 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Fixed the getkey command handling in the server. Send just
1207 empty OK reply to the sender if the key could not be fetched
1208 (but everything else was ok, like the key just was not available).
1209 Changed the public key parameter to optional in the protocol
1210 specs so that empty OK reply can be sent. Affected file
1213 Added a message to Irssi SILC client to tell to user if the
1214 server did not return a public key.
1216 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Fixed a channel key regeneration bug. It registered new
1219 timeout tasks exponentially until all system resources were
1220 used. Affected file silcd/server.c.
1222 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Added the SILC Document generator to the scripts/silcdoc.
1225 It can be used to generate the Toolkit Reference Manual out
1226 of the source tree. Internally it will also use the RoboDoc
1227 generator now imported in util/robodoc.
1229 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1231 * Added couple of return's in rekey protocol if error orccurred
1232 during the protocol. The execution must be terminated.
1233 Affected file silcd/protocol.c. Also, terminate the protocol
1234 always with timeout.
1236 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * The client's Client ID was created initally from the wrong
1239 nickname (it could have been in format nick@host) in the
1240 silc_server_new_client. Affected file silcd/packet_receive.c
1242 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Added some SILC_LOG_ERROR's to various error conditions
1245 if client could not be added to ID cache. Affected files
1246 silcd/packet_receive.c and silcd/server.c.
1248 * When client's sock->user_data is freed, NULL also the
1249 client->router and client->connection pointers. Added check
1250 for these pointers being NULL to various places around the
1251 code. Affected file silcd/server.c.
1253 * Added client->data.registered == TRUE checks to various
1254 places around the code to assure that unregistered client's
1255 are not handled when it is not allowed. Affected file
1258 * Added `bool registered' fields to all
1259 silc_idlist_[server|client]_get_* routines to indicate whether
1260 the fetched client needs to be registered or not. Affected
1261 file silcd/idlist.[ch].
1263 * Add your own entry as registered to the ID cache in the
1264 server. Affected file server.c.
1266 * Fixed a bug in silc_server_new_server. The SilcServer was
1267 set as the new server's context instead of SilcServerEntry.
1268 This naturally caused some weird bugs.
1270 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Do not delete the channel rekey task when adding it
1273 for in silc_server_create_channel_key.
1275 * Changed the silc_server_create_channel_key to return
1276 TRUE or FALSE to indicate the success of the channel key
1279 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Fixed MSVC++ project files and added missing files to
1282 Makefiles under win32/.
1284 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Do not add TCP_NODELAY flag if the operating system
1287 does not have it defined. Affected files are
1288 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1290 * Fixed buffer overflow from Irssi SILC Client. Affected
1291 file irssi/src/fe-common/core/themes.c.
1293 * Fixed double free in client library in the file
1294 lib/silcclient/client.c when disconnecting from server.
1296 * Applied double free patch from cras to Irssi SILC client.
1297 Affected files irssi/src/core/[modules/expandos].c
1299 * Fixed the disconnection handling to Irssi SILC Client.
1300 The application must call silc_client_close_connection
1301 in ops->connect client operation in case of failure of
1302 the connection. Affected file is
1303 irssi/src/silc/core/client_ops.c.
1305 * Do not set sock->protocol to NULL in the function
1306 silc_client_close_connection after executing the protocol's
1307 final callback since the sock might not be valid anymore.
1308 Affected file lib/silcclient/client.c.
1310 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Do not enable SILC_THREADS if the linking with libpthread
1313 did not happen. Affected file configure.in.pre.
1315 * Added notion to protocol specification that server must
1316 verify the sent authentication payload with CMODE when
1317 setting the channel founder key. Implemented it to the
1318 server. Affected file silcd/command.c.
1320 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Added _EXTRA_DIST SILC distribution variable to the
1323 distributions file. It is used to conditionally add extra
1324 files or directories to the specific distribution. Affected
1325 files ./prepare, Makefile.am.pre and distributions.
1327 Removed the `_' from the start of the distribution names.
1330 * Added README.WIN32 for instructions to compile the Toolkit
1333 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Fixed a double free in disconnection in the server. Affected
1336 file is silcd/server.c.
1338 * Fixed the lib/silcske/groups.c to work now also with GMP
1339 MP library. The string conversion did not work when using
1340 specific base and the base is indicated in the string as well.
1342 * Created win32/ directory which now includes MSVC++ specific
1343 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1344 It will appear only in the toolkit distribution
1346 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Changed the key material distribution function in case when
1349 the hash output is too short. The data is now concatenated
1350 a bit differently than it used to. Made the change to the
1351 SKE protocol specification.
1353 * Added better GMP detection to configure.in.pre. A patch
1356 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed a minor bug in SKE that might cause some problem on
1359 some platforms. Affected file lib/silcske/silcske.c.
1361 * Added the cookie checking for initiator in the SKE. It checks
1362 that the responder returns the sent cookie unmodified. The
1363 affected file is lib/silcske/silcske.c. Added new SKE
1364 error type INVALID_COOKIE that can be sent during the
1365 negotiation. Fixed some memory leaks as well.
1367 * Added the "invalid cookie" error message to Irssi SILC client's
1370 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Added `task_max' field to the SilcClientParams to indicate
1373 the maximum tasks the scheduler can handle. If set to zero,
1374 default values are used. Affected file lib/silcclient/silcapi.h.
1376 * Fixed memory leaks in silc_client_close_connection. Affected
1377 file lib/silcclient/client.c.
1379 * Added silc_client_del_client_entry to client library to free
1380 all memory of given client entry. Affected file is
1381 lib/silcclient/idlist.[ch].
1383 * Added new functions silc_client_del_channel and
1384 silc_client_del_server to delete channel and server entries.
1385 Affected file lib/silcclient/[silcapi.h/idlist.c].
1387 * Removed silc_client_del_client_by_id from silcapi.h.
1389 * Fixed the INFO command to return the server's own info
1390 correctly when querying by Server ID. Affected file is
1393 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Removed the non-blocking settings in WIN32 code in the
1396 silc_sock_[read/write] and added SleepEx instead. Affected
1397 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1398 of input data is now checked with FIONREAD and ioctlsocket.
1400 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Call silc_schedule_task_del_by_context in the
1403 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1404 Affected file lib/silccore/silcprotocol.c.
1406 * Call silc_protocol_cancel for active protocols in the
1407 silc_server_close_connection if the funtion
1408 silc_server_free_sock_user_data has not been called.
1409 Affected file silcd/server.c.
1411 * Generic tasks cannot be deleted using the del_by_fd
1412 task deleting function since generic tasks does not match
1413 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1415 * Added a notion to SILCOPER help file that the SILCOPER works
1416 only on router server, not on normal server.
1418 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Added for WIN32 support for the new scheduler as well.
1421 Affected file lib/silcutil/win32/silcwin32schedule.c.
1423 * Fixed the SHA1 implementation to work on various platforms.
1425 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1428 API. It is part of the scheduler now. Everything else is
1429 as previously but some functions has changed their names.
1430 Checkout the lib/silcutil/silcschedule.h for the interface.
1431 Updated all applications to use the new interface. Affected
1432 files are lib/silcutil/silcschedule.[ch].
1434 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Found a bug in the SKE implementation. The HASH value,
1437 specified by the protocol, was not computed correctly. The
1438 public key of the responder was not added to the computation
1439 even though it is mandatory. Affected file lib/silcske/silcske.c.
1440 This unfortunately causes incompatibilities with older
1441 clients and servers.
1443 * Added WIN32 specific network init and uninit functions:
1444 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1445 the Winsock2. Affected file lib/silcutil/silcnet.h and
1446 lib/silcutil/win32/silcwin32net.c.
1448 * Set the socket always to nonblocking mode on WIN32 after
1449 reading data or writing data. Affected file is
1450 lib/silcutil/win32/silcwin32sockconn.c.
1452 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Fixed various compilation problems under WIN32. Affected
1455 files lib/silcutil/win32/silcwin32thread.c and
1456 lib/silcutil/win32/silcwin32schedule.c.
1458 * Removed all _internal.h #includes from public header
1459 files. Internal headers must never be included from
1462 Removed also the lib/silcske/payload_internal.h file.
1464 * All include files that may be needed (public and some others
1465 included by the public headers) by application developers are
1466 now copied to the ./includes directory. It does not copy any
1467 internal headers. Affected file Makefile.defines.pre and all
1468 Makefile.am's under lib/ and subdirs.
1470 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Do not change the ~/.silc directory's permissions automatically.
1473 Affected file irssi/src/silc/core/clientutil.c.
1475 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Do not cancel the protocol in silc_server_close_connection
1478 it might cause recursion. Now cancelled in the function
1479 silc_server_free_sock_user_data. Affected file silcd/server.c.
1481 * Fixed the silc_server_remove_clients_by_server to regenerate
1482 the channel keys correctly finally. Added also new function
1483 silc_server_remove_clients_channels to actually do it.
1484 Affected file silcd/server.c.
1486 * Fixed the silc_server_new_channel to not crash by giving
1487 wrong router to the new channel. Affected file is
1488 silcd/packet_receive.c.
1490 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1493 which is given as argument to the silc_client_alloc now.
1494 It can be used to configure the client and set various parameters
1495 that affect the function of the client.
1497 * The USERS command in server did not check whether the channel
1498 is private or secret. Affected file silcd/command.c.
1500 * Added new argument to the USERS command in protocol specification.
1501 The USERS command now can take the channel name as argument
1502 as well. Added support for this in client and server and
1503 updated the protocol specs.
1505 * Completed the GETKEY command in client. It can be now used
1506 to fetch also servers public key not only some clients.
1507 Affected files lib/silcclient/command[_reply].c.
1509 * Added silc_client_get_server to return server entry by the
1510 server name. Affected files lib/silcclient/silcapi.h and
1513 * Redefined the IDENTIFY command in protocol specification to be
1514 more generic. It now can be used to query information about
1515 any entity in the SILC Network, including clients, servers and
1516 channels. The query may be based either the entity's name
1517 or the ID. Added support for this in both client and server.
1519 Affected files silcd/command.c and lib/silcclient/command.c
1520 and command_reply.c.
1522 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1523 the _from_client and _from_server functions. Affected file
1526 * Added silc_client_get_channel_by_id_resolve to the file
1527 lib/silcclient/silcapi.h to resolve channel information by
1528 its ID. Added also silc_client_get_channel_by_id that
1529 does not resolve it from the server.
1531 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Added SilcServerEntry context into the client library
1534 to represent one server. The INFO command now allocates
1535 these to save the resolved server info. For now on the
1536 client library will also keep information about servers,
1537 connected and resolved with INFO.
1539 The INFO command now allocates the SilcServerEntry context
1540 and saves the server info there. The COMMAND_REPLY in
1541 the INFO now returns the parameters to application in
1542 same order as defined in the protocol specification.
1544 The entries are cached in the client->server_cache.
1546 * The INFO command is now issued after received the Client ID
1547 from the server. Affected file lib/silcclient/client.c.
1549 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1550 to the application as the mode changer might be server.
1551 It is guaranteed that NULL is not returned anymore to the
1552 application. Affected file lib/silcclient/client_notify.c.
1554 The ID Type is now also passed to the application so that
1555 it can check whether the returned entry is SilcClientEntry
1558 Added new function silc_client_get_server_by_id to return
1559 the server entry by ID. Affected files are the
1560 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1562 * Do not create the channel in the Irssi SILC Client when issuing
1563 the JOIN command but when received the sucessful JOIN command
1564 reply. Otherwise the channel might get created even though we
1565 could not join it. The Affected file is
1566 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1568 * Fixed a channel joining bug in router. The router must also
1569 check the channel modes, invite and ban lists etc. when serving
1570 the JOIN command sent by normal server. Affected file is
1571 silcd/command.c. The router now resolves the client's
1572 information from the server who sent the JOIN command if it
1573 does not know it, and processes the JOIN command only after
1576 * Changed the SilcCommandCb to take new argument; void *context2.
1577 Affected file lib/silccore/silccommand.h
1579 The second argument in the command callbacks in the server now
1580 includes the SilcServerCommandReplyContext if the command was
1581 called as pending command callback from the command reply.
1582 Otherwise it is NULL. When called as pending the status of the
1583 command reply will be checked and if it was erronous the
1584 error will be sent to the original sender of the command.
1585 This way the client always receives the error messages even
1586 though the server was actually the one who received the error
1587 when it resent the command to router, for example. Affected
1588 files silcd/command[_reply].[ch].
1590 * Fixed sending WHOWAS command's error message to client if
1591 the requested client could not be found. It was missing.
1594 * Changed the CMODE and CUMODE commands reply arguments in the
1595 protocol specification. The Channel ID is now sent in both
1596 of the commands to identify the channel. Implemented this
1597 new feature to the client and server. Affected files
1598 lib/silcclient/command_reply.c and silcd/command.c.
1600 * Made better checks for invite and ban lists in the JOIN
1601 command in server. Affected file silcd/command.c.
1603 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * The server now performs the incoming host IP/DNS lookup
1606 using the silc_socket_host_lookup and thus does not block
1607 the server anymore. Affected file silcd/server.c.
1609 * Completed the multi-thread support for SILC Scheduler in
1610 the lib/silcutil/silcschedule.c.
1612 * Fixed the configure.in.pre to detect the pthread correctly
1615 * Fixed a deadlock in silc_task_queue_wakeup in the file
1616 lib/silcutil/silctask.c.
1618 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Added new function silc_schedule_wakeup that is used in
1621 multi-threaded environment to wakeup the main thread's
1622 schduler. It needs to be used when a thread adds a new task
1623 or removes a task from task queues. After waking up, the
1624 scheduler will detect the task queue changes. If threads
1625 support is not compiled in this function has no effect.
1626 Implemented the wakeup mechanism to both Unix and WIN32
1627 systems. Affected files are lib/silcutil/silcschedule.[ch],
1628 lib/silcutil/unix/silcunixschedule.c and the
1629 lib/silcutil/win32/silcwin32schedule.c.
1631 * Added new function silc_task_queue_wakeup to wakeup the
1632 scheduler by the specified task queue. Affected file
1633 lib/silcutil/silctask.[ch].
1635 * The silc_socket_host_lookup_start now wakes up the scheduler
1636 after adding the timeout task. Affected file is
1637 lib/silcutil/silcsockconn.c.
1639 * The silc_socket_host_lookup is synchronous now if the threads
1640 support is not compiled in. However, the callback is still
1641 called asyncronously through the scheduler, anyway. Affected
1642 file lib/silcutil/silcsockconn.c.
1644 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Added new function silc_socket_host_lookup to perform
1647 asynchronous IP and FQDN lookups for the socket connection.
1648 Affected files lib/silcutil/silcsockconn.[ch].
1650 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1652 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1653 that may or may not compile the mutex support in.
1655 Changed the silc_mutex_alloc interface. It allocates the
1656 mutex now to the sent pointer and returns TRUE or FALSE.
1658 Affected file lib/silcutil/silcmutex.h.
1660 * Wrote the SILC Task Queue interface to support multi-threads.
1661 Affected file lib/silcutil/silctask.[ch].
1663 * Wrote the SILC Scheduler to support multi-threads. Affected
1664 file lib/silcutil/silcschedule.c.
1666 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1669 in lib/silcutil/win32/.
1671 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Defined SILC Mutex API and SILC Thread API and implemented
1674 them for Unix. Affected files are
1675 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1676 lib/silcutil/unix/silcunixmutex.c and
1677 lib/silcutil/unix/silcunixthread.c.
1679 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Fixed the silc_server_remove_clients_by_server's channel
1682 key re-generation. The hash table handling was incorrect
1683 and would not work with many channels. Affected file is
1686 * Fixed some memory leaks around the server code.
1688 * Rewrote the silc_server_get_users_on_channel to support IPv6
1689 based Client ID's. Affected file silcd/server.c.
1691 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1692 specification. However, a separate document must be written
1693 to define the detailed signing procedure and the payload
1694 associated with the flag. Defined the flag to the
1695 lib/silccore/silcchannel.h as well.
1697 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Changed the dynamic tables to static size tables in the
1700 lib/silccrypt/silchmac.c.
1702 * Removed GCC dependencies from the code. A patch by cras.
1704 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1706 * Do not show the error "Error receiving packet bla bla"
1707 in server if it really was not an error (-2 means that reading
1708 is pending). Affected file silcd/server.c.
1710 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Fixed a possible crash in silc_server_remove_clients_by_server
1713 in silcd/server.c. Fixed there also some memory leaks.
1715 * Fixed the silc_idlist_replace_client_id. It could replace
1716 wrong key in the hash table. Affected file silcd/idlist.c.
1718 * Do not check whether there are global users on the channel
1719 if the channel->global_users is FALSE. Affected functions
1720 silc_server_remove_from_one_channel and
1721 silc_server_remove_from_channels in silcd/server.c. Also,
1722 do not check if the removed client is local as we can be
1723 sure that global client was not removed from the channel
1724 and checking for global users is not needed.
1726 * The silc_server_remove_clients_by_server now re-generates
1727 the channel keys correctly for those channels that had
1728 clients removed from them. Affected file silcd/server.c.
1730 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Found the reason of random crashes in the server. We weren't
1733 ignoring the SIGPIPE signal (which can be sent in write())
1734 and it crashed the server. Affected file silcd/silcd.c.
1736 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Assure that sock->user_data is not NULL in the function
1739 silc_server_packet_send in silcd/packet_send.c.
1741 * Disconnect the remote connection if it could not be added
1742 to any ID lists in the server. The affected file is
1745 * Check in silc_server_packet_send[_real/dest] that the
1746 socket is not disconnecting and ignore the data if it is.
1747 Affected file silcd/packet_send.c.
1749 * Define inline to __inline on native WIN32 compilation.
1750 Affected file includes/silcwin32.h.
1752 * Added some explicit type casts for inline code since MSVC
1753 require them. Affected files lib/silcutil/silcbuffer.h,
1754 lib/trq/silcdlist.h and lib/trq/silclist.h.
1756 * Print warning in log files from now on if the packet
1757 decryption fails. Affected file silcd/server.c.
1759 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Changed the `say' client operation's interface to accept
1762 new `type' argument to indicate the type of the message sent
1763 by the library. The application may filter the library's
1764 messages according the type. The affected file is the
1765 lib/silcclient/silcapi.h.
1767 * Added two new functions to lib/silcclient/silcapi.h:
1768 silc_client_del_client and silc_client_del_client_by_id.
1769 Affected file lib/silcclient/idlist.c.
1771 * Moved the clientincludes.h from includes/ to silc/ and
1772 serverincludes.h from includes/ to silcd/.
1774 * The modes for the CMODE and CUMODE are now passed as
1775 uint32 for application with COMMAND_REPLY. The affected
1776 file is lib/silcclient/command_reply.c.
1778 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * /WHOIS without arguments shows client's own information.
1781 Affected file lib/silcclient/command.c.
1783 * Changed PING to not accept any arguments. The specs
1784 says that client can ping only the connected server so
1785 requiring an argument is not needed. Affected file is
1786 lib/silcclient/command.c.
1788 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Fixed a fatal bug in private message sending and reception
1791 encryption and decryption when using private message keys.
1792 The implementation was incorrect and did not follow the
1793 specification. It causd that some of the message were
1794 lost since it did not use the sending and receiving keys
1795 as the protocol suggests. This has been fixed and will cause
1796 incompatibilities with older clients when sending private
1797 message encrypted with private message keys. Affected files
1798 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1799 and various other in Irssi SILC Client.
1801 Added `responder' boolean argument to the functions
1802 silc_client_add_private_message_key[_ske] to indicate when
1803 the key is added as responder or initiator of the key
1806 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Removed the silc_ske_check_version function and created
1809 a SilcSKECheckVersion callback. Added also a function
1810 silc_ske_set_callbacks that is now used to set all SKE
1811 callbacks. The callback functions are not given to
1812 the SKE functions anymore, but this function is used to
1815 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1817 * Added `silc_version' argument to the silc_client_alloc
1818 to define the version of the application for the library.
1819 The library will use the version string to compare it
1820 against the remote host's (usually a server) version
1821 string. Affected file lib/silcclient/silcapi.h
1823 * Added the KE protocol context to Key Agreement context
1824 in client library so that we can abort the SKE if it
1825 is in process when we get timeout. Affected file is
1826 lib/silcclient/client_keyagr.c.
1828 * Do not resolve the client ID forever if it returns in the
1829 first time that such client does not exist. This was done
1830 for example with private message. Affected file is
1831 lib/silcclient/client_prvmsg.c.
1833 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * Do not add regex.h for WIN32. The affected file
1836 includes/silcincludes.h.
1838 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1839 not work yet 100%. It generates the DLL's automatically
1840 when compiling with --with-win32 under cygwin.
1842 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * lib/contrib/regex.c is not compiled on WIN32.
1846 * Added silc_net_get_socket_opt function to the
1847 lib/silcutil/silcnet.h.
1849 * Added includes/silcwin32.h for WIN32 specific includes
1852 * Do not use ptime structure or any of the posix process
1853 functions on WIN32 in lib/silccrypt/silrng.c.
1855 * Added silc_gettimeofday to provide generic function
1856 for struct timeval on all platforms. Added the function
1857 to lib/silcutil/silcutil.h.
1859 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1862 library as they clearly belong there. As a plus side we
1863 can make the actual socket connection routines platform
1866 Added also new generic function silc_socket_read and
1867 silc_socket_write (that used to be silc_packet_[read/write].
1868 The implementation of these are platform specific.
1870 * Added WIN32 specific routines of silc_socket_[read/write]
1871 to lib/silcutil/win32/silcwin32sockconn.c.
1873 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Added preliminary support for native WIN32 compilation under
1876 cygwin (using the -mno-cygwin option for GCC) to the
1877 ./configure.in.pre. The --with-win32 now prepares the
1878 compilation for native WIN32.
1880 * Rewrote the SILC Scheduler interface in the file
1881 lib/silcutil/silcschedule.h. The scheduler is now context
1882 based and does not have anymore any global static scheduler.
1883 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1884 and created lib/silcutil/win32 directory for WIN32 based
1887 * Added Unix specific network routines to the
1888 lib/silcutil/unix/silcunixnet.c and the old
1889 lib/silcutil/silcnet.c includes now only generic routines.
1891 Added WIN32 specific network routines to the
1892 lib/silcutil/win32/silcwin32net.c.
1894 * Added Unix specific utility functions from the
1895 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1897 * Added WIN32 SILC Scheduler to the file
1898 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1901 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Do not handle JOIN notify in the server if the target client
1904 is not registered (idata->registered == FALSE). The affected
1905 file is silcd/packet_receive.c.
1907 * Update the nickrec->founder in event_cumode in the Irssi SILC
1908 client. Affected file irssi/src/silc/core/silc-channels.c.
1910 * Fixed the CUMODE_CHANGE notify handling in the server when
1911 server and router are announcing their clients on channels.
1912 Now the mode changes are saved and notified correctly. The
1913 affected file is /silcd/packet_receive.c.
1915 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1916 They really did not replace the cache entry in the ID Cache.
1917 Now they do that. Affected file silcd/idlist.c.
1919 * Fixed the KICK notify handling in the Irssi SILC client to
1920 update the channel records so that the kicked client does not
1921 appear to be on the channel. The affected file is
1922 irssi/src/silc/core/silc-channels.c.
1924 * Always update the conn->current_channel when executing command
1925 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1927 * Fixed the KILL notify handling in Irssi SILC client to remove
1928 the killed client on all channels.
1930 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Fixed the silc_parse_command_line to remove extra spaces
1933 from the start and end of the arguments. Affected file is
1934 lib/silcutil/silcutil.c.
1936 * Cancel and free any active protocol in the function
1937 silc_server_close_connection. Affected file silcd/server.c.
1939 * Cancel and free any active protocol in the function
1940 silc_client_close_connction. Affected file is
1941 lib/silcclient/client.c.
1943 * Do not execute the KILL command for clients that are in
1944 history (ie. they are not in the network). Affected file is
1947 * Fixed KILL notify handling, client does not crash anymore.
1948 Affected file irssi/src/silc/core/silc-channels.c.
1950 * Reduced the default packet buffer size from 2048 to 1024 in
1951 lib/silccore/silcpacket.c.
1953 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1954 counter to the SKE context that is incresed when the SKE library
1955 performs async operation outside the library. If the outside
1956 process frees the SKE context and FREED status will be set
1957 and the library will detect after the sync operation that the
1958 libary is freed. The affected files are
1959 lib/silcske/silcske[_status].[ch].
1961 * Resolve the client entry information in the function
1962 silc_client_channel_message to assure that NULL pointer is not
1963 passed as client entry to the application. */
1965 * Fixed the task timeout calculation to assure that there is
1966 never negative timeouts. The affected file is
1967 lib/silcutil/silcschedule.c.
1969 * Fixed the channel user mode notification sending in server.
1970 It was sent point-to-point to the router (or to server by router)
1971 but it needs to be destined to a channel. The routines now
1972 supports sending the channel user mode notifys to the channels
1973 when announcing clients and channels. Affected files are
1974 silcd/server.c and silcd/packet_receive.c.
1976 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1977 It did not actually replace the old channel entry in the cache.
1978 Affected file lib/silcclient/client_notify.c.
1980 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Fixed a possible crash in silc_packet_send_prepare. It now
1983 assures always that there is enough space in the buffer and
1984 at the tail area of the buffer (for MAC).
1986 Fixed the inbound buffer reallocation in silc_packet_read.
1987 It was old code and did not handle the reallocation correctly.
1990 The affected file is lib/silccore/silcpacket.c.
1992 * Fixed buffer overflow in silc_parse_nickname in the file
1993 lib/silcutil/silcutil.c.
1995 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * make install generates new server keys only if there is not
2000 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2002 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2003 Added check that if the NOREPLY is set then we will not send
2004 the away message. This avoids infinite loop of away messages
2005 if both clients are away. The affected file is
2006 lib/silcclient/client_prvmsg.c.
2008 * Fixed client crash if /NICK was given without arguments.
2009 Affected file lib/silcclient/command.c.
2011 * Server does not send the invite list in INVITE command back
2012 to the client if the list was not altered. Added this notion
2013 to the protocol spec as well. Affected file silcd/command.c.
2015 Fixed possible crash in INVITE command by checking the
2016 value of silc_server_get_client_route command.
2018 * Fixed the INVITE notify type handling. The arguments are now
2019 taken in correct order and client does not crash. The affected
2020 file is irssi/src/silc/core/silc-channels.c.
2022 Removed the "Inviting xxx to channel" message from the
2023 client library away and let the application handle it.
2024 Affected file lib/silcclient/command.c. Added that message
2025 to Irssi SILC client's message formats.
2027 * Fixed CMODE command crash in client. It now checks the
2028 amount of arguments correctly and does not crash. The affected
2029 file is lib/silcclient/command.c.
2031 * Do not create new channel automatically in silc_channels_join
2032 but check whether the channel by that name already exists.
2033 Affected file irssi/silc/core/silc-channels.c.
2035 * Do not send the SERVER_SIGNOFF to router if the disconnected
2036 entity was the router. Affected file silcd/server.c.
2038 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2039 SILC client as it was missing from there.
2041 Added the handling of the KICK notify to the Irssi SILC client
2042 as it was missing. Added "you have been kicked" message to
2043 Irssi SILC client's message modules formats.
2045 Added the handing of the KILL notify to the Irssi SILC client
2046 as it was missing. Added the kill message module formats
2049 The affected file is irssi/src/silc/core/silc-channels.c.
2051 * The router did not save the channel mode the server announced.
2052 Affected file silcd/packet_receive.c.
2054 * Fixed a possible crash in INFO command in server. If the
2055 server did not provide the server info it crashed. Affected
2056 file silcd/command.c.
2058 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Fixed the GETKEY command in the server to check also the
2061 global list. Otherwise the GETKEY would not work correctly
2062 in normal SILC server. Affected file silcd/command.c.
2064 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Fixed GETKEY crash, it crashed if the command did not succseed.
2068 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2071 is now real and not just an macro interface to GMP.
2073 Removed the entire GMP from the source tree and imported new
2074 NSS MPI library instead. Reason for removing GMP is that it is
2075 extremely large and compiles extremely slow. The NSS MPI
2076 is only a few files and compiles in less than 10 seconds.
2077 The speed is also about the same as GMP. The MPI is imported
2078 to lib/silcmath/mpi.
2080 If the system has GMP installed we will still use the GMP.
2081 If it is not then the NSS MPI will be compiled.
2083 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Merged a long nickname (127 characters long) crash bugfix from
2086 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2088 * Merged a freed memory reference bugfix from Irssi CVS tree.
2089 Affected file irssi/src/core/commands.c.
2091 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Added the server's public key sving and verification to the
2094 server when performing the SKE. This was missing and the
2095 remote server's (or router's) public key was accepted without
2096 checking whether we have it previously or trust it at all.
2097 Affected file silcd/protocol.c.
2099 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Check in the silc_server_timeout_remote if protocol is active
2102 and make sure that the protocol's final callback is called so
2103 that all memory if freed. Affected file silcd/server.c.
2105 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * silc_server_whois_send_reply crashed the server if the nickname
2108 was 127 characters long. Affected file silcd/command.c.
2110 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added sanity check to the silc_server_new_client. If the hostname
2113 is provided inside username then check that the provided hostname
2114 really is the same as the resolved one. If the hostname was not
2115 resolved then check it from the public key. Affected file is
2116 silcd/packet_receive.c.
2118 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2119 if the server disconnected us and the connection is not valid
2120 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2122 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2123 the library to the lib/silcutil/silcutil.[ch].
2125 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Close log file after open. Affected file
2128 lib/silcutil/silclog.c.
2130 * Check whether sock == NULL in silc_client_send_packet and return
2131 if it is. Affected file lib/silcclient/silcclient.c.
2133 * Check rec->entry == NULL in the Irssi SILC Client before
2134 sending the channel message. Affecte file is
2135 irssi/src/silc/core/silc-servers.c.
2137 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Merged a splitted window bugfix from Irssi CVS tree. The
2140 affected file is irssi/src/fe-text/textbuffer-view.c.
2142 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2143 It did not print nickname.
2145 * Improved the distributions system a bit.
2147 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2150 irssi/src/fe-text/gui-window.c.
2152 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2153 to in-active server. The affected file is
2154 irssi/src/silc/core/client_ops.c.
2156 * Resolve the client in USERS command reply if the entry does
2157 not have username resolved. The affected file is
2158 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2159 command to WHOIS command to really resolve stuff. The USERS
2160 is not used any more in any critical section so WHOIS can
2161 be used even though it might be slower than IDENTIFY.
2163 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2166 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Changed the protocol API a bit more consistent in the
2169 lib/silccore/silcprotocol.[ch].
2171 * Changed the following headers to ROBODoc format:
2173 lib/silccore/silcpayload.h
2174 lib/silccore/silcprotocol.h
2175 lib/silccore/silcsockconn.h
2177 All core library headers are now formatted.
2179 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2181 * Fixed a bug in Irssi SILC client; do not show that you are
2182 server/router operator if you really are not. Affected file is
2183 irssi/src/silc/core/client_ops.c.
2185 * Renamed silc_command_free_payload to silc_command_payload_free.
2186 Affected file lib/silccore/silccommand.h
2188 * Added silcmath.h to include the prototoypes of various routines
2189 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2192 * Changed the following headers to ROBODoc format:
2194 lib/silccore/silcchannel.h
2195 lib/silccore/silccommand.h
2196 lib/silccore/silcid.h
2197 lib/silccore/silcidcache.h
2198 lib/silccore/silcmode.h
2199 lib/silccore/silcnotify.h
2200 lib/silccore/silcpacket.h
2201 lib/silcmath/silcmath.h
2203 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Added checking to the server code not to start the server if
2206 ciphers and stuff are not configured properly. Affected files
2207 silcd/serverconfig.[h] and silcd/server.c.
2209 * Changed the layout of the header files of the public interfaces
2210 in the SILC libraries. The new layout supports ROBODoc
2211 documentation tool (and some others) so that it is easy to create
2212 a library reference manual. All the other headers and source
2213 code must still follow the CodingStyle document. Also source
2214 code must not include these ROBODoc stuffs, only the headers.
2215 Furthermore, all public interface headers must now be named
2216 by using `silc' prefix, example: silcapi.h, silccipher.h.
2217 Some files were renamed due to this. All the other headers
2218 must not be used as public interfaces. I will update the
2219 CodingStyle document later. Changed following headers, so far:
2221 lib/silcclient/silcapi.h
2222 lib/silccore/silcauth.h
2223 lib/silccore/silcprivate.h
2224 lib/silccrypt/silcdh.h
2226 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Removed silc_client_packet_send_flush from the client library
2231 as it is not needed. Affected file lib/silcclient/client.[ch].
2233 * Added printing of message of unresolved authentication method
2234 to the Irssi SILC client. Added it to the module formats.
2235 Removed the same message from the client library.
2237 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Added new distribution feature, DISTLABEL. Every distribution
2240 can define own preprocessor label that can be used in the
2241 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2242 file distributions, acconfig.h.pre and prepare.
2244 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Added Makefile.defines_int to include the actual definitions
2247 for Makefile.defines.in. Tested the new distribution system,
2248 created distributions and tested installation.
2250 * Added AWAY message printing to the Irssi SILC client. Added
2251 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2253 * Added SCONNECT command to call the SILC's CONNECT command.
2254 Cannot use CONNECT directly since Irssi uses that internally.
2255 Affected file irssi/src/silc/core/silc-servers.c.
2257 Added ACTION local command. It is same as ME command but takes
2258 the channel as mandatory argument.
2260 Rewrote some of the Irssi's help files to suite for SILC
2263 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * Added Makefile.defines[.in] that should for now on be included
2266 in all Makefile.am file in the source tree. That file includes
2267 all common compilation definitions for SILC source tree.
2269 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Minor changes to the ./prepare script to change the package
2272 name according the distribution name to the configure.in.
2274 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Created new distribution system. Added file `distributions'
2277 that defines all the distributions that can be created out of
2278 the SILC source tree. The ./prepare script now reads that
2279 file to determine how to prepare the distributions. The
2280 first argument to the ./prepare is the name of the distribution
2281 and second is the version of the distribution. If given
2282 without arguments it creates the default (toolkit) distribution
2283 with the default version (defined in ./prepare).
2285 All Makefile.am files that are subject to the distributions
2286 are now named as Makefile.am.pre. These are ./Makefile.am
2287 and lib/Makefile.am. Others may be changed later.
2289 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Added invite list, ban list, some key management and connection
2292 error message printing to module formats in the Irssi SILC client.
2294 * Added new silc_client_set_away_message to set the away message
2295 that is back to the person who sent private message. The
2296 affected file lib/silcclient/silcapi.h and the
2297 lib/silcclient/client_prvmsg.c.
2299 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Fixed the private message sending in the Irssi SILC client,
2302 added local command KEY to the Irssi SILC client.
2304 Added key management and key agreement message formats to the
2305 irssi/src/fe-common/silc/module-formats.[ch].
2307 Added USERS (alias WHO) printing, server/router operator
2308 indication and LIST command printing to the module formats.
2310 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Fixed channel joining notify handling, cumode notify handling
2313 from Irssi SILC client.
2315 * Added SILC specific module-formats to the Irssi SILC client so
2316 that SILC specific message hilighting, colors etc is possible.
2317 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2319 Added channel mode, channel user mode, actions, notices,
2320 whois and whowas printing to the the module-formats.c.
2322 * Fixed a bug in channel deletion in the server. The channel
2323 is not left to the cache even if the channel founder auth mode
2324 is set when there are no users anymore on the channel. Affected
2325 file silcd/server.c.
2327 * The silc_net_localhost now resolves the entire hostname including
2328 the domain name. Affected file lib/silcutil/silcnet.c.
2330 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Changed the ask_passphrase client operation to be ascynchronous.
2333 It has now a completion callback and a context that the
2334 application must call after it has got the passphrase from
2335 the user. Affected files lib/silcclient/silcapi.h,
2336 lib/silcclient/protocol.c, lib/silcclient/command.c and
2339 Added SilcAskPassphrase callback that the application calls
2340 to deliver the passphrase to the library.
2342 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2343 The public key verification and especially a certificate
2344 verification is asynchronous procedure.
2346 Added new SILC_SKE_STATUS_PENDING status to indicate the
2347 request is pending and a callback will be called to finalize
2350 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2351 indicate that remote end did not send its public key (or
2352 certificate), even though we require it. Added check for this
2353 condition in the SKE. This was a security bug, now fixed.
2355 Defined new SilcSKEVerifyCbCompletion callback that is called
2356 when the verification process is completed.
2358 The affected files lib/silcske/silcske_status.h and
2359 lib/silcske/silcske.[ch].
2361 * Changed the verify_public_key client operation to be async
2362 as well. Defined SilcVerifyPublicKey callback that is used to
2363 indicate the success of the public key verification process.
2365 Changed the server and client to use the new async client
2368 * Changed the Irssi SILC client's internal scheduler to be called
2369 twice as many times as it used to be. As a result the client
2370 should be a bit faster now. Affected file is
2371 irssi/src/silc/core/silc-core.c.
2373 * Added support to Irssi SILC client of asynchronous public key
2374 verification and passphrase inquiry. Affected file is
2375 irssi/src/silc/core/silc-core.c.
2377 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Do not say "You have left channel %s" in client library.
2380 Moved it to the application. Affected files are
2381 lib/silcclient/command.c and silc/client_ops.c.
2383 * Fixed silc_client_get_clients. Command context was not
2384 duplicated and was freed memory in the callback. Affected
2385 file lib/silcclient/idlist.c.
2387 * Do not say "you are now talking..." on JOIN command in the
2388 client library. The appliation must handle it.
2390 * Do not say ".. changed topic to" in command reply in the
2391 client libary. The application must handle it.
2393 * Fixed TOPIC command sending in the client library.
2395 * Fixed a memory leak in silc_client_command_free in the file
2396 lib/silcclient/command.c.
2398 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Imported a modified version of Irssi client to the source tree.
2401 The Irssi will be used to create a new client called
2402 Irssi SILC. Imported to irssi/.
2404 Added silc_core_init_finish function to the Irssi. Affected
2405 file irssi/configure.in.
2407 A lot changes in the Makefile.ams around the irssi tree.
2409 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Do not rehash if the new size is same as the old size of the
2412 hash table, in the silc_hash_table_rehash*. The affected file
2413 lib/silcutil/silchashtable.c.
2415 * Replaced hash_table_del_by_context calls from the server
2416 (when channel->user_list and client->channels) to the
2417 hash_table_del as it is sufficient and faster.
2419 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Added silc_hash_table_list, silc_hash_table_get and the
2422 SilcHashTableList structure to provide an alternative way to
2423 traverse the hash table. The affected files are
2424 lib/silcutil/silchashtable.[ch].
2426 * Changed the server's idlist routines to use the hash table
2427 routines to optimize the code.
2429 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Replaced the client entry's `channel' list and channel entry's
2432 `user_list' list to hash tables for optimized lookup. Changed
2433 the code to use the hash table interface around the code.
2434 Affected file lib/silcd/idlist.[ch].
2436 * Added `auto_rehash' boolean argument to the function
2437 silc_hash_table_alloc to indicate whether the hash table should
2438 auto-rehash when it thinks is appropriate time. It will
2439 increase the hash table size if the there is twice as much
2440 entries in the table than the size of the table, and will
2441 decrease the size if there are twice as less entries than
2442 the size of the table.
2444 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2448 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * silc_idcache_purge_by_context deletes the entry now by context
2451 as it is supposed to do. Affected file lib/silccore/idcache.c.
2453 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2454 client is not anymore valid (WHOWAS givens the info) and not
2455 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2457 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Removed the `data' and `data_len' arguments from the ID Cache
2460 interfaces and added `name' argument. ID Cache does not handle
2461 anymore the binary data only a names associated with given ID.
2463 * When hashing a Client ID with silc_hash_id the entire ID is
2464 not hashed anymore, instead only the hash of the Client ID is
2465 hashed. This way we can access the Client ID from the cache
2466 with Client ID but with the hash of the ID (which is a hash of
2467 the nickname) as well without any difference in performance.
2469 Added also silc_idcache_find_by_id_one_ext to do one on one
2470 searching when we have the actual ID. Added also function
2471 silc_hash_client_id_compare. The affected files are
2472 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2474 * When hashing the name associated with a ID it is always done
2475 in lowercase. This way we can access the cache without worrying
2476 about case-sensitivity, even though, for example nicknames are
2479 * Fixed a bug in server with channel message sending. It put
2480 wrong ID type as destination ID. The affected file
2481 silcd/packet_send.c.
2483 * silc_idcache_del_by_context now deletes from all hash tables
2484 by context. Affected file lib/silccore/idcache.c.
2486 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * Changed the client library to use the new ID Cache interface.
2489 Changes around the source tree.
2491 * Added silc_hash_table_rehash_ext to rehash with specific
2492 hash function. Affected file lib/silcutil/silchashtable.[ch].
2494 * Added silc_hash_string_compare to compare two strings in the
2495 hash table. Affected file lib/silcutil/silcutil.[ch].
2497 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Added new function silc_idcache_del_by_context into the
2500 lib/silccore/idcache.[ch].
2502 * Changed the server's ID list routines to use the new ID Cache
2503 interface. Changes around the source tree.
2505 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Added silc_hash_table_del[_by_context]_ext functions in to the
2508 lib/silcutil/silchashtable.[ch].
2510 Removed silc_hash_table_find_all* routines and added new
2511 silc_hash_table_find_foreach to replace them.
2513 Added silc_hash_table_replace_ext function as extended
2514 replacing function. Separated the simple hash table interface
2515 from the extended hash table interface in the file
2516 lib/silcutil/silchashtable.h.
2518 * Fixed minor bugs and changed it to use some of the new
2519 hash table functions in lib/silccore/idcache.c
2521 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2523 * Added new function silc_hash_table_find_all to return all keys
2524 in the hash table by the specified key. As the hash table is
2525 collision resistant it also makes it possible to have several
2526 duplicate keys in the hash table. This function may be used to
2527 find all of the keys from the hash.
2529 Added user_context arguments to the SilcHashFunction,
2530 SilcHashCompare and SilcHashDestructor to deliver user specified
2533 Added new fuctions silc_hash_table_find[_all]_ext to do
2534 extended lookup with specified hash and compare functions and
2535 specified user contexts.
2537 Added new function silc_hash_table_add_ext to add the key
2538 with specified hash function and user context.
2540 Added new function silc_hash_table_foreach to traverse all
2541 entrys in the hash table. Added SilcHashForeach callback
2544 Added new function silc_hash_table_del_by_context to delete
2545 the entry only if the context associated with the key matches.
2547 Affected files are lib/silcutil/silchashtable.[ch].
2549 * Removed silc_hash_[server/client/channel]_id and added just
2550 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2551 silc_hash_id_compare to compare two ID's using as the hash table
2552 comparison function. Added also silc_hash_data to hash
2553 binary data and silc_hash_data_compare to compare it.
2555 * Removed silc_idlist_find_client_by_hash as it is not needed
2556 anymore. Affected file silcd/idlist.[ch].
2558 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2559 to use internally the SilcHashTable. The new ID Cache is a lot
2560 faster than the old one. Some of the ID Cache interface was also
2561 rewritten and obsolete and stupid functions were removed.
2563 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2565 * Added entry_count field to the SilcHashTable to keep the number
2566 of the entries in the table. Implemented the function
2567 silc_hash_table_rehash. Added new function
2568 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2570 Fixed a minor bug in silc_hash_table_free.
2572 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2573 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2574 into the lib/silcutil/silcutil.[ch].
2576 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Implemented a collision resistant hash table into the
2579 lib/silcutil/silchashtable[ch]. See the header and the source
2580 for the SilcHashTable API.
2582 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Merged dotconf version 1.0.2 into lib/dotconf.
2586 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Do not compile anything in lib/silcsim/* if the SIM support
2589 is not enabled. The tree should now compile without problems
2592 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Compiled the SILC under cygwin. Compiled and tested briefly
2595 without problems. More tests needed. The SIMs didn't compile
2598 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2600 * Fixed possible crash in silc_get_username in the
2601 lib/silcutil/silcutil.c.
2603 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Fixed a va_arg in silc/client_ops.c.
2607 * Oops, RC5 routines were named AES and caused some problems
2608 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2610 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added new SilcIDIP structure into the lib/silccore/id.h and
2613 replaced the old `ip' fields from all SILC ID's to that type.
2614 This is a step towards IPv6 support.
2616 The silc_id_get_len takes now the ID as an extra argument.
2617 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2618 both IPv4 and IPv6 based ID's.
2620 The affected files are lib/silccore/id.[ch] and other files
2621 around the tree using these routines.
2623 * Removed the ID length arguments in server from various
2624 silc_server_send_notify_* routines -> they are not needed
2627 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Fixed memory leak in silc_encode_pem_file in the file
2630 lib/silcutil/silcutil.c.
2632 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Check minor version as well in the SKE. Affected files are
2635 silcd/protocol.c and lib/silcclient/protocol.c.
2637 * Added --identifier option to the server so that an identifier
2638 can be when creating the public key for the server. Affected
2639 file is silcd/silcd.c.
2641 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2642 lib/silccrypt/silcpkcs.c.
2644 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Register default ciphers and stuff when using -C option with
2647 the server. Affected file sildc/silcd.c.
2649 * Put back the servers public key filename format, it is better
2650 than the new one. For now, the client keys are saved with the
2651 new filename format. The affected file silc/client_ops.c.
2653 * Implemented the Cipher API for the rest of the ciphers that
2654 did not implement it or implemented it the wrong way.
2656 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Register default ciphers and stuff when using the -S option
2659 in the client. Affected file silc/silc.c. Same also when
2660 creating new key pair with -C option.
2662 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Fixed the silc_verify_public_key client operation function to
2665 save the public keys differently. The fingerprint is now
2666 used as filename and not the hostname. This way also the
2667 client keys are saved uniquely and not with hostnames. The
2668 affected file is silc/client_ops.c.
2670 * Trimmed the silc_hash_fingerprint function to remove extra
2671 whitespaces from the end of the fingerprint. The affected
2672 file is lib/silccrypt/silchash.c.
2676 * Added silc_cipher_register_default function to register all
2677 default ciphers. It can be used when configuration files
2678 does not exist and the application does not want any specific
2679 ciphers in any specific order.
2681 The SilcDList is now used as silc_cipher_list dynamically
2682 allocated cipher list. Removed the static list all together
2683 and now all ciphers must be allocated to the dynamic list.
2684 The silc_cipher_alloc routine was changed to check only the
2687 All silc_cipher_* routines that used to return int returns
2690 The affected files lib/silccrypt/silccrypt.[ch].
2692 * The same thing was done to silc_hash_* as for silc_cipher_*
2693 routines. Affected files lib/silccrypt/silchash.[ch].
2695 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2696 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2697 Added also silc_pkcs_[un]register[_default] functions.
2698 Removed the data_context from the PKCS API.
2700 * Added silc_hmac_register_default function to register default
2701 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2702 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2703 to unregister all hmacs at once.
2705 * Register the default ciphers, hash functions, PKCSs and HMACs
2706 if client's configuration file does not exist. The affected
2709 * The client did not load the hash functions from the SIM
2710 modules at all. Added support for this. Affected file is
2711 silc/clientconfig.c.
2713 * When decoding public key with silc_pkcs_public_key_decode, check
2714 the supported algorithm only if PKCS are registered. Affected
2715 file lib/silccrypt/silcpkcs.c. The same was done with the
2716 silc_pkcs_private_key_decode.
2718 * Fixed the SILC List routines to keep the list always in order.
2719 It used to change the list's order when traversing the list but
2720 not it preserves the order. Affected file lib/trq/silclist.h.
2722 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Added the client library to use the SilcSocketConnection's
2725 reference counter (by silc_socket_dup) to prevent the bug that
2726 the socket object may be freed underneath async operation.
2728 * The name resolv library checking fixes in the configure.in.pre.
2731 * Created new version of the protocol drafts for future
2732 development. The -03 drafts are the ones that will be changed
2733 in the trunk now and the -02 will remain as they are.
2735 * Send list of CUMODE notifys to the router when announcing
2736 the channel users to the router. Affected file silcd/server.c.
2737 If the router receiving channel founder CUMODE for a channel
2738 that already has channel founder it will send CUMODE notify
2739 to the sender to remove the channel founder rights from the
2740 announced client. Affected file silcd/packet_receive.c.
2742 * The CUMODE notify may now use Server ID as well as the entity
2743 who changes the mode. Updated protocool specs.
2745 * Updated INSTALL and README files.
2747 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * New web pages in the http://silc.pspt.fi. The pages was
2754 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * Implemented the [DenyConnectin] config section in the server.
2757 Added silc_server_config_denied_conn to check whether incoming
2758 connection is denied. Affected file silcd/serverconfig.[ch].
2760 * Do not check the ports when checking the incoming configuration
2761 data if the port is 0, meaning any. Affected file is
2762 silcd/serverconfig.c.
2764 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Fixed buffer overflow in silc_string_compare in the file
2767 lib/silcutil/silcutil.c.
2769 * Fixed double free in silc_server_command_leave in the file
2772 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Fixed the version checking in the server. Affected file is
2777 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Fixed the configuration data fetching when accepting new
2780 connections in the server. Affected file silcd/server.c.
2782 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Added `sender_entry' argument to the function
2785 silc_server_packet_relay_to_channel so that we can check
2786 whether some destination actually belongs to the same route
2787 the sender belongs (ie, we must not resend the packet to the
2788 sender). Affected file silcd/packet_send.[ch].
2790 * Added `servername' field to the SilcClientEntry in the server
2791 to hold the name of the server where client is from. Affected
2792 file is silcd/idlist.h.
2794 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Moved the channel message encrypting in the router betwen
2797 router connections from silc_server_channel_message to the
2798 silc_server_packet_relay_to_channel since we want to check
2799 whether we have anybody channel before encrypting anything.
2800 Affected files silcd/packet_[receive/send].c.
2802 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Fixed the [AdminConnection] server config section to support
2805 multiple entries. Affected file silcd/serverconfig.c.
2807 * Added support into the server to check the validity of the
2808 incoming connection before executing any KE or authentication
2811 * The connection configuration is now saved to the KE and
2812 connection auth protocol contexts and not fetched anymore in
2813 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2815 * The local hosts listenning address and port is also resolved
2816 now when starting the server. We want to have the socket object
2817 to include the real address and port for the listener. Added
2818 new function silc_net_check_local_by_sock into the files
2819 lib/silcutil/silcnet.[ch].
2821 * Fixed a broadcast bug in server -> do not broadcast if we
2824 * Fixed a routing bug. Do not route broadcast packets ever.
2825 Broadcast packets must be processed always and not routed since
2826 they may be destined to some other host than yourself and thus
2827 would get routed without no good reason. Affected file is
2830 * Added function silc_server_config_is_primary_route to check
2831 whether primary router connection has been configured (a router
2832 configuration that we are initiating). If there is not, we
2833 will assume that there is only two routers in the SILC network
2834 and we will use the incoming router connection as our primary
2835 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2837 * Changed the order of the broadcasting. Broadcast _after_ the
2838 packet has been processed not before. Affected file is
2841 * Fixed a [ClientConnection] parsing bug. The port was never
2842 parsed correctly thus resulting to port 0. Affected file
2843 silcd/serverconfig.c.
2845 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2846 argument and did not set the broadcast packet flag. Affected
2847 file silcd/packet_send.c. Fixed same bug in the function
2848 silc_server_send_notify as well.
2850 * If we receive NEW_ID packet for our own ID in the server, ignore
2853 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Removed the nickname from the Private Message Payload.
2858 Updated the code and the protocol specs.
2860 * Updated protocol specs for submitting to the IETF.
2862 * Tweaked the Random Number Generator a bit. Affected file
2863 lib/silccrypt/silcrng.c. Exported a new function
2864 silc_rng_[global]_add_noise which can be used to add more
2867 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Do not parse packets with different timeout when protocol
2870 is active -> may cause problem with rekey. Affected file
2873 * When server receives signoff notify it must not create
2874 new channel key if the client is on any channels since the
2875 sender of the signoff notify will create it.
2877 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Added printing of error messages during SKE protocol from the
2880 failure packet sent by server during SKE. Affected file
2883 * Removed the client's failure_callback handling with timeout
2884 and handle it immediately when received.
2886 * The SKE library returned wrong type in SUCCESS and FAILURE
2887 packets. They must be 32 bit MSB not 16 bit MSB.
2889 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Ok, rewrote the logic of the re-key and now it seems to work.
2892 I tested it on high traffic with frequent re-keys without
2893 problems. Added hmac_receive (and renamed hmac to hmac_send)
2894 in SilcClientConnection in lib/silcclient/client.h and
2895 in SilcIDListData in silcd/idlist.h. Also, removed the
2896 SilcPacketParserContext's cipher and hmac fields as they are
2897 not needed anymore and actually caused some problems when
2898 the ciphers and hmac's changed underneath the packet parser.
2900 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * If re-key protocol is active then process the incoming packets
2903 synchronously since we must assure that icoming packets encrypted
2904 with the old key is processed before the new keys is set to
2905 use. This is true other packets than for REKEY packets.
2906 Affected file silcd/server.c. The same was done to client library
2907 as well, affected file lib/silcclient/client.c.
2909 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Fixed bug in client and server to accept the force send if
2912 the packet is send from silc_[server/client]_packet_process
2913 function. Otherwise the packets are never delivered, oops.
2915 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Disable force sending of packets when REKEY protocol is active.
2918 We must assure that no packet is sent directly when rekey is
2919 performed. All packets must be sent through packet queue.
2920 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2921 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2922 function is silc_[server/client]_packet_send_real to check
2925 * Replaced the SIM paths from example config files to
2926 /usr/local/modules. Also, make install creates now
2927 /usr/local/silc/logs directory to hold all the SILC server
2930 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Made the configure.in.pre work on Solaris. Patch by salo.
2934 * Made all ciphers compatible with non-x86 machines. Defined
2935 CBC mode macros into lib/silccrypt/ciphers_def.h.
2937 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * Fixed the make install.
2941 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2943 * When MAC computation fails the silc_packet_decrypt returned 0
2944 even though it was supposed to return -1. Fixed this. The
2945 affected file is lib/silccore/silcpacket.c.
2947 * Do not replace the config files in /etc/silc (in make install)
2948 if they already exist. Affected file ./Makefile.am.
2950 * Do not send re-key packets immediately but through packet queue.
2951 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2953 * Changed silc_net_check_host_by_sock to return FALSE if the
2954 IP/DNS could not be resolved. Though, it returns the IP address
2955 now even if it could not resolve it (but returns also FALSE).
2956 Affected file lib/silcutil/silcnet.[ch].
2958 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Added silc_pkcs_decode_identifier to decode the public key's
2961 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2962 Added also silc_pkcs_free_identifier. Added also new context
2963 SilcPublicKeyIdentifier.
2965 * Added -S option to the silc client. It is used to dump the
2966 contents of the specified public key file.
2968 * Changed the PKCS api to return the public key length when
2969 setting the public key.
2971 * Fixed a fatal bug in the public and private key file loading.
2972 Affected file lib/silccrypt/silcpkcs.c.
2974 * Execute the packet parsing for client with zero (0) timeout
2975 if the protocol is active. Affected file silcd/server.c.
2977 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Made the key generation options to the silcd program. Added
2980 -C option, equivalent to client's option.
2982 * Added new [ServerKeys] config section to the server. It
2983 configures the server's public and private key.
2985 * Defined generic Public Key Payload into the protocol
2986 specification to send specific type of public keys and
2989 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2990 public key or certificate.
2992 * Implemented the GETKEY command to the server and to the
2993 client library and on user interface.
2995 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Made preliminary `make install' work.
2999 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Added SilcServerRekey context into silcd/idlist.h.
3003 * Added the PFS support as defined in the specification to the
3004 SKE protocol. Affected files lib/silcske/*.c.
3006 * Added `ske_group' field to the SilcServerRekey context to hold
3007 the number of the SKE group that is used with PFS in re-key.
3008 Affected file silcd/idlist.h.
3010 * Added PFS re-key support to the server. Affected file is
3013 * Added silc_protocol_cancel to cancel execution of the next
3014 state of the protocol. Affected file is
3015 lib/silccore/silcprotocol.[ch].
3017 * Added the re-key support with and without PFS to the client
3018 library. Re-key is performed once in an hour, by default.
3020 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3021 Added silc_client_rekey_callback and silc_client_rekey_final.
3022 Affected files are lib/silcclient/protocol.[ch] and
3023 lib/silcclient/client.[ch].
3025 * Removed the `hmac_key' and `hmac_key_len' fields from the
3026 SilcClientConnection structure; not needed. Affected file is
3027 lib/silcclient/client.h.
3031 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Do not ask whether user wants to use the negotiated private key
3034 for private messages, just use it. Affected file is
3035 silc/local_command.c.
3037 * Added `send_enc_key' and `enc_key_len' fields to the
3038 SilcIDListData structure since they are needed in the re-key
3039 phase. Affected file is silcd/idlist.[ch].
3041 * Implemented the simple re-key protocol into the server.
3042 Affected files silcd/server.c and silcd/protocol.[ch]. The
3043 re-key will be performed once in an hour, by default.
3045 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3046 Added silc_server_rekey, silc_server_rekey_callback and
3047 silc_server_rekey_final.
3049 * Removed Tunneled flag from the protocol. Updated the code
3050 and the specifications.
3052 * Adde `pfs' field to the SilcIDListData to indicate whether
3053 the PFS is to be performed in the re-key. Affected file is
3056 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3059 int64 of at least the xintXX size. If void * is less that 4
3060 bytes uint32 * will be used. Defined bool as boolean.
3062 * Changed _ALL_ unsigned long and unsigned int to uint32,
3063 unsgined short to uint16 in the source tree.
3065 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3066 not handle clients that has entry->data.registered == FALSE.
3067 They are not in the network anymore. Affected file is
3070 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Implemented the sending of the SERVER_SIGNOFF notify in the
3073 server. Affected file is silcd/server.c.
3075 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3076 Added also silc_notify_payload_encode_args into the
3077 lib/silccore/silcnotify.[ch].
3079 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3080 Affected file silcd/packet_receive.c.
3082 * Implemented the SERVER_SIGNOFF notify handling in the client
3083 library. Affected file lib/silcclient/client_notify.c. Also,
3084 implemnted the printing of the SERVER_SIGNOFF info to the
3085 application. Affected file silc/client_ops.c.
3087 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3088 if the deleting was successful. Affected file silcd/idlist.[ch].
3090 * Added support for public key authentication in the connection
3091 authentication protocol in the client library. Affected file
3092 lib/silcclient/protocol.c.
3094 * Changed the server's silc_idlist_get_clients_by_* interface
3095 to support already allocated array so that new entries may be
3096 added to pre-allocated array. Affected file silcd/idlist.[ch].
3097 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3098 and command replies.
3100 * All command reply functions in the server now calls the
3101 pending command callback even if error occured. This way the
3102 error will be delivered to the client as well. Affected files
3103 silcd/command.c and silcd/command_reply.c.
3105 * Fixed INFO command to return local server's info if no server
3106 was provided. Affected file lib/silcclient/command.c.
3108 * Removed RESTART command for good. Updated the code and the
3111 * Rewrote parts of the task system. It is a bit simpler now.
3112 Removed unsued task priorities. The affected files are
3113 lib/silcutil/silctask.[ch].
3115 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Moved the USERS printing from the library to the application.
3118 Affected files lib/silcclient/command.c and silc/client_ops.c.
3120 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added channel key re-key support. The re-key is perfomed
3125 only by the router and is done once in an hour. Added `rekey'
3126 field to the SilcChannelEntry in the server. Affected files
3127 silcd/server.c and silcd/idlist.h.
3129 * Added silc_task_unregister_by_context into the file
3130 lib/silcutil/silctask.[ch].
3132 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Added SILC_UMODE_GONE mode to indicate when the client is not
3135 present in the SILC network. Added also support to the local
3136 command AWAY that will set this mode. Added support of showing
3137 "xxx is gone" in WHOIS command. The USERS command shows the
3138 gone status as well.
3140 * Fixed setting server and router operator privileges in the
3141 server's UMODE command. Affected file silcd/command.c.
3143 * Merged the SKE KE1 and KE2 payloads into one payload. The
3144 new KE payload is equivalent to the old KE2 payload.
3146 Cleaned up the SKE Start Payload parsing. It now uses the
3147 simple buffer unformatting to do the parsing. A lot faster
3150 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3151 to the SKE that is used to indicate whether both of the SKE
3152 parties should perform authentication. By default only the
3153 responder performs authentication. By setting this flag also
3154 the initiator must do authentication. By default it is unset
3155 since in normal SKE case, client to server connection, only
3156 the responder should do authentication. When doing SKE between
3157 two clients both should perform authentication. Updated the
3158 code and the protocol specs.
3160 * A little fix to IDENTIFY command in the server. Search the
3161 client first by hash not nickname. Affected file is
3164 * Fixed the silc_client_close_connection to support closing
3165 the client to client connections wihtout deleting too much
3166 data. Affected file lib/silcclient/client.c.
3168 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3169 are received if protocol used to be active but is not anymore
3170 the application would crash due to NULL pointer dereference.
3171 Affected files silcd/server.c and lib/silcclient/client.c.
3173 * Added `hash' field to the SilcClientConnection to include
3174 the hash function negotiated in the SKE protocol.
3176 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3177 to set the channel founder authentication data. A client can
3178 claim the founder rights later by providing the authentication
3179 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3180 This way the channel founder can regain the channel founder
3181 privileges even it is left the channel. This works only on
3182 local server and the client must be connected to the same
3183 server to be able to regain the founder rights. Updated the
3184 protocol specs accordingly.
3186 Added support to the CMODE command in the client to set the
3187 founder auth data. Read the README to see how to set it.
3189 Added support to the CUMODE command to claim the founder
3190 rights. Read the README to see how to do it.
3192 Added support for the founder authentication to the Channel
3193 Entry in the server. Affected file silcd/idlist.h.
3195 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3196 server's CMODE command. Affected file silcd/command.c.
3198 * Added the following new functions into lib/silccore/silcauth.[ch]:
3199 silc_auth_get_method and silc_auth_get_data.
3201 * The server now saves the remote hosts public key to the
3202 SilcIDListData pointer. Affected file silcd/protocol.c.
3204 * The normal server now does not remove the channel entry from
3205 the cache if the founder authentication data is set. It used
3206 to remove it if the founder was the last one on the channel on
3207 the server and left the channel. The auth data is saved and
3208 if the channel is re-joined later the old entry is used with
3209 the old auth data. Affected files silcd/command_reply.c and
3212 * Removed the `pkcs' field from the SilcIDListData structure
3213 in the server; it is not used. Affected file silcd/idlist.h.
3215 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Fixed packet processing on slow links. Partial packets were
3218 never re-processed because the incoming data buffer was cleared
3219 by the application. Application must not directly clear the
3220 sock->inbuf, the packet processing routines handle it. Fixed
3221 this in client library and in server.
3223 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Fixed the WHOIS and IDENTIFY send reply function to really
3226 check whether to send list or just one entry. Affected file
3229 * Cleaned up the LEAVE command's channel key distribution. The
3230 affected file silcd/command.c.
3232 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3233 can enforce the channel mode as well. In that case the ID
3234 includes the ID of the server. The code now enforces the
3235 mode change if the router have different mode than the server.
3237 * The notify client operation with CMODE_CHANGE notify can now
3238 return NULL client_entry pointer if the CMODE was not changed
3239 by client. Application must check for this.
3241 * Added <Server ID> argument to INFO command to support server
3242 info fetching by Server ID.
3244 * Added silc_server_announce_get_channel_users to get assembled
3245 packets of channel users of the specified channel. Affected
3246 file silcd/server.[ch].
3248 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3249 was freed underneath the ID Cache.
3251 * Re-announce clients when the server received CHANNEL_CHANGE
3252 notify from the router. Affected file silcd/packet_send.c.
3254 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3257 crashed since it did not handle the fact that there is no cipher
3258 called "3" and didn't check the error condition. Now fixed.
3260 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3261 flag. It can be used to send message requests.
3263 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Implemented the RESTART command in the client.
3267 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3268 notice type messages. Added notice printing to the user
3271 * The channel keys are not re-generated if the channel's mode
3272 is PRIVKEY, ie private key on the channel exists. Affected
3273 files silcd/server.c and silcd/command.c.
3275 * Fixed a little bug in channel message delivery when channel
3276 private keys are set in the server. Affected file is
3277 silcd/packet_send.c.
3279 * Changed the setting on channel->on_channel = TRUE from the
3280 silc_client_save_channel_key to the JOIN command reply. The
3281 key payload is not received if the private channel key is set.
3282 Affected file lib/silcclient/command_reply.c and the
3283 lib/silcclient/client_channel.c.
3285 * When the CMODE_CHANGE notify is sent and the channel private
3286 key mode is removed the channel key must be re-generated in
3287 other cells as well. Added this support for the router in the
3288 silcd/packet_receive.c.
3290 * Added new local command NOTICE to send notice message on
3291 channel. Affected file silc/local_command.[ch].
3293 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Added new local command ME to the client. It is used to send
3296 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3297 some action. Affected file silc/local_command.[ch].
3299 * Changed channel_message and private_message client operations
3300 to deliver the message flags to the application. Added also
3301 the `flags' arguments to the silc_client_send_channel_message
3302 and silc_client_send_private_message functions. Affected file
3305 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Redefined the Private Message Payload to support private message
3308 keys and to support the new private message flags. Updated
3309 the protocol specs. Flags makes it possible to have for example
3310 CTCP style messages.
3312 * Added new type SilcPrivateMessagePayload and defined an API
3313 for it in the lib/silcclient/silcprivate.[ch].
3315 * Tested private message private keys successfully. Tested the
3316 private message key set, unset and list commands with the new
3319 * Redefined the Channel Message Payload to include the channel
3320 message flags (equal with private message flags) to support
3321 for example CTCP style messages.
3323 * Defined some of the message (for channel and private message)
3324 flags. Updated the protocol specs and added the flags to the
3325 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3327 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added SilcKeyAgreementStatus type to the key agreement routines
3330 to indicate the current status and error if one occured.
3331 The status types are defined in the lib/silcclient/silcapi.h.
3333 * Added new local command KEY that is used to set and unset private
3334 keys for channels, set and unset private keys for private messages
3335 with remote clients and to send key agreement requests and
3336 negotiate the key agreement protocol with remote client. The
3337 key agreement is supported only to negotiate private message keys,
3338 it currently cannot be used to negotiate private keys for channels,
3339 as it is not convenient for that purpose.
3341 * Fixed a minor pending callback setting bug in the function
3342 silc_client_get_client_by_id_resolve, now the function works.
3343 Affected file lib/silcclient/idlist.c.
3345 * Added function silc_net_get_local_port to get local bound
3346 port by socket. Added to lib/silcutil/silcnet.[ch].
3348 * Added `sockets' and `sockets_count' fields to the SilcClient
3349 object. They hold the sockets of the listenning sockets in
3350 the client. Listenning sockets may be for example the key
3351 agreement server. Affected file lib/silcclient/client.[ch].
3352 Added functions the silc_client_add_socket and the
3353 silc_client_del_socket. They are exported to the application
3356 * Added ~./silc/clientkeys to support other client's public keys.
3358 * Renamed verify_server_key client operation to verify_public_key
3359 and added one argument to indicate the type of the connection
3360 (server, client etc.).
3362 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Added silc_server_connection_auth_request to handle the
3365 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3366 silcd/packet_receive.[ch].
3368 * Added silc_server_send_connection_auth_request into the
3369 silcd/packet_send.c to send the connection auth request packet.
3371 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3374 * Fixed the public key authentication in responder side in the
3375 server. The `auth_data' pointer includes the SilcPublicKey
3376 not the path to the public key. Affected file silcd/protocol.c.
3378 * Implemented the public key authentication in the initiator side
3379 in the server. Affected file silcd/protocol.c.
3381 * Removed the [RedirectClient] config section from the server
3382 configuration. Is not needed and I don't want to implement it.
3384 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Cleaned up the CMODE command in the server. It now works
3387 correctly and supports all the modes defined in the protocol.
3388 Affected file is silcd/command.c.
3390 * Added `hmac_name' field to the SilcChannelEntry in the server
3391 to hold the default HMAC of the channel. It can be set when
3392 creating the channel (with JOIN command). Affected files
3395 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3396 type to indicate the change of the current cipher and hmac
3397 on the channel. Client can safely ignore the <cipher> argument
3398 (if it chooses to do so) since the CHANNEL_KEY packet will
3399 force the channel key change anyway. The <hmac> argument is
3400 important since the client is responsible of setting the new
3401 HMAC and the hmac key into use.
3403 * Fixed the CMODE command in the client library as well.
3405 * Tested CMODE command in router environment successfully.
3407 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Show the version of the remote client (or server) when connecting
3410 to the server. It is logged to the log file. Affected file
3411 is silcd/protocol.c.
3413 * Fixed the KILLED notify handling in the client library. The
3414 client must be removed from all channels when receiving the
3417 Also, do not remove the client entry when giving the KILL
3418 command but when the KILLED notify is received.
3420 * Removed silc_idlist_find_client_by_nickname from the server.
3421 Not needed anymore. Affected files silcd/idlist.[ch].
3423 * Implemented the CHANNEL_CHANGE notify type handling to the
3424 server. Affected file silcd/server.c.
3428 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Added silc_server_send_notify_invite to send the INVITE
3431 notify between routers.
3433 * Implemented the INVITE command correctly to the server.
3435 * Implemented the INVITE notify type handling in the server.
3437 * Implemented the INVITE command to the client library and on the
3440 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Added function silc_server_get_client_resolve to find the
3443 client entry by ID from all ID lists and then resolve it
3444 (using WHOIS) if it cannot be found. Affected file is
3447 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Implemented the BAN command to the client library.
3451 * The JOIN command in the server now checks the invite list
3454 * Changed the silc_command_reply_payload_encode_va and the
3455 silc_command_payload_encode_va to support that if argument is
3456 NULL it ignores and checks the next argument. Affected file
3457 lib/silccore/silccommand.c.
3459 * Added silc_server_send_notify_ban to send the BAN notify
3460 type between routers.
3462 * Chaned the silc_notify_payload_encode to support that if
3463 argument is NULL it ignores and checks the next argument.
3464 Affected file lib/silccore/silcnotify.c.
3466 * Tested ban lists in router environment successfully.
3468 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Implemented BAN command to the server, in silcd/command.[ch].
3472 * Removed the BAN and INVITE_LIST modes from the CMODE command
3475 * Added function silc_string_match to regex match two strings.
3476 Affected files lib/silcutil/silcutil.[ch].
3478 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Redefined parts of the SilcChannelEntry in the server to support
3481 the new ban and invite lists.
3483 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Redefined the INVITE command. The same command can be used to
3486 invite individuals to the channel but also to manage the invite
3487 list of the channel (to add to and remove from the invite list).
3488 Updated the protocol specs.
3490 * Added new command SILC_COMMAND_BAN that can be used to manage
3491 the ban list of the channel. Updated the protocol specs.
3493 * Removed the channel modes: the SILC_CMODE_BAN and the
3494 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3495 in the CMODE command. The equivalent features are now available
3496 using INVITE and BAN commands. Updated the protocol specs.
3498 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3499 in the network about change in the current ban list. The notify
3500 type is not used by the client.
3502 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3503 support the invite lists.
3505 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Added new function silc_string_regexify that converts string
3508 including wildcard characters into regex string that can
3509 be used by the GNU regex library. Added into the file
3510 lib/silcutil/silcutil.[ch].
3512 Added silc_string_regex_combine to combine to regex strings
3513 into one so that they can be used as one regex string by
3514 the GNU regex library. Added into the file
3515 lib/silcutil/silcutil.[ch].
3517 Added silc_string_regex_match to match two strings. It returns
3518 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3520 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Imported GNU regex to the soruce tree into lib/contrib.
3523 Fixed some compiler warning from the regex.c.
3525 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Fixed MOTD command in the server to work in router environment.
3529 * Fixed the MOTD command in the client library to support
3530 the server argument in the command.
3532 * Added `nickname_len' argument to the silc_idlist_add_client
3533 in the server, as the `nickname' argument may be binary data
3536 * Added silc_idlist_get_channels to return all channels from
3539 * Implemented LIST command to the server. Affected file is
3542 * Implemented the LIST command to the client library and on the
3545 * Added [<user count>] argument to the LIST command reply.
3546 With private channels the user count is not shown.
3548 * Updated TODO and README.
3550 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * The client entry's data.registered must be TRUE even with
3553 global client entry on global client list. The data.registered
3554 is used to check whether the client is anymore in the network,
3555 for example with WHOWAS command so it must be valid.
3557 * Fixed the WHOWAS command in the server. It now actually works
3558 in router environment. Added function into silcd/command_reply.c
3559 silc_server_command_reply_whowas_save.
3561 * Added silc_idlist_purge function to the silcd/idlist.c
3562 to periodically purge the ID Cache.
3564 * Fixed INFO command in the server. It works now in router
3565 environment. Added <server name> argument to the INFO command
3566 reply. Updated the protocol specs.
3568 * Fixed minor bug in silc_idcache_purge to not purge if the
3569 expire value is zero.
3571 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3572 they were buggy because of the WHOWAS information.
3574 * Fixed local command MSG to handle the async resolving of
3575 the remote client properly. It used to fail the first MSG.
3576 Affected file silc/local_command.c.
3578 * Added `data_len' field to SilcIDCache context.
3580 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Update TODO. Todo in commands in the server.
3584 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3587 used by routers as broadcast packet to inform other routers
3588 about the changed user mode.
3590 Implemented the notify handling in the server. Affected file is
3591 silcd/packet_receive.c. Added the function
3592 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3594 * Added new generic Channel Payload and deprecated the New Channel
3595 Payload. The New Channel Payload is now the generic Channel
3598 * Added new argument `mode' to the silc_server_send_new_channel
3599 as it is required in the Channel Payload now.
3601 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3602 and created a new and real SilChannelPayload to represent the
3603 new generic Channel Payload. Implemented the encode/decode
3604 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3606 * Added silc_server_get_client_channel_list to return the list
3607 of channels the client has joined for WHOIS command reply.
3608 Affected file silcd/server.[ch].
3610 * Implemented the channel list sending in the WHOIS command reply
3611 in server and in the client.
3613 Implemented the channel list displaying on the user interface
3614 as well. Affected file silc/client_ops.c.
3616 * Added silc_channel_payload_parse_list to parse list of Channel
3617 Payloads. It returns SilcDList list of SilcChannelPayloads.
3618 Client for example can use this function to parse the list of
3619 channels it receives in the WHOIS command reply. The caller
3620 must free the list by calling silc_channel_payload_list_free.
3621 Affected files lib/silccore/silcchannel.[ch].
3623 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Added one new argument <user mode> to the WHOIS command reply
3626 to return the mode of the user in SILC. Updated the protocol
3629 Implemented it to the server and client.
3631 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Fixed the mode printing on the user interface on joining.
3634 Affected file silc/client_ops.c.
3636 * Implemented the UMODE command and user modes in general to the
3637 client library and to the user interface.
3639 * Implemented the UMODE command to the server.
3641 * The server now sends UNKNOWN_COMMAND error status if client sends
3642 unknown command. Affected file silcd/command.c.
3644 * All server commands now handle the command identifier the right
3645 way when sending the command reply to the client. The client can
3646 use to identify the command replies with the identifier.
3648 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Added silc_server_get_client_route to resolve the route to
3651 the client indicated by the client ID. Affected file is
3654 * Added silc_server_relay_packet as general function to relay
3655 packet to arbitrary destination. This deprecates functions
3656 like _send_private_message_key, _relay_notify etc. Affected
3657 file is silcd/packet_send.[ch].
3659 Removed silc_server_send_key_agreement,
3660 silc_server_send_private_message_key and
3661 silc_server_packet_relay_notify functions from the file
3662 silcd/packet_send.[ch].
3666 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3667 server. Affected file silcd/packet_receive.[ch].
3669 * Implemented the KILL command to the client. Implemented the
3670 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3671 Affected files lib/silcclient/command[_reply].c and
3672 lib/silcclient/client_notify.c. Implemented the KILL notify
3673 printing in the user inteface.
3675 * Fixed a lot silc_parse_nick memory leaks from the client
3676 library in the file lib/silcclient/command.c.
3678 * Changed the silc_server_send_notify_on_channels's `sender'
3679 argument from SilcSocketConnection to SilcClientEntry to
3680 check the sender as entry and not as connection object and not
3681 to send to the client provided as argument. The affected file
3682 is silcd/packet_send.[ch].
3684 * The notify packets that are destined directly to the client used
3685 to not to be processed by the server. Now changed that and the
3686 server processes all notify packets. After relaying the packet
3687 to the client the notify packet is processed in the server.
3689 * The silc_server_free_client_data now checks whether there is
3690 pending outgoing traffic for the client and purges the data to
3691 the network before removing the client entry.
3693 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3696 an client is killed from the SILC Network. Updated the protocol
3699 Added new function silc_server_send_notify_killed to the
3700 silcd/packet_send.[ch].
3702 * Added function silc_server_packet_relay_notify to relay notify
3703 packets that are destined directly to a client. In this case
3704 the server does not process the notify packets but merely relays
3705 it to the client. Affected file silcd/packet_send.[ch].
3707 Added also silc_server_packet_process_relay_notify to check
3708 whereto relay the notify. Affected file is
3709 silcd/packet_receive.[ch].
3711 * Implemented the KILL command to the server.
3715 * Added the backup schema desgined last fall to the protocol
3716 specs for everyone to see. The specification is in the
3717 *-spec-xx.txt draft and the packet type definitions for the
3718 backup routers is in *-pp-xx.txt draft. Thusly, added also
3719 new packet type SILC_PACKET_CELL_ROUTERS.
3721 * A big security problem in the implementation discovered. The
3722 signoff of an client did not cause new channel key generation
3723 which it of course should've done. The channel keys must be
3724 always re-generated when client leaves (or signoffs) the channel.
3725 The silc_server_remove_from_channels funtion now handles
3726 the channel key re-generation.
3728 * Added `sender' argument to the silc_server_send_notify_on_channels
3729 to not to send the client provided as argument. Affected file
3730 silcd/packet_send.[ch].
3732 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Implemented OPER and SILCOPER commands into the server and
3737 * Added silc_auth_verify and silc_auth_verify_data to verify
3738 the authentication directly from the authentication payload.
3739 It supports verifying both passphrase and public key based
3740 authentication. Affected file lib/silccore/silcauth.[ch].
3742 * Added `hash' field to the SilcIDListData structure. It is the
3743 hash negotiated in the SKE protocol. Affected file is
3746 * Slight redesigning of the SilcAuthPayload handling routines.
3747 Do not send SilcPKCS but SilcPublicKey as argument.
3749 * Implemented the public key authentication support to the
3750 serverconfig. The public key is loaded from the provided path
3751 and saved as authentication data to void * pointer. Thus,
3752 changed the unsigned char *auth_data to void *auth_data;
3754 * Fixed SHUTDOWN command to send the reply before the server
3755 is shutdown. :) Affected file silcd/command.c.
3757 * Fixed fatal bug in CONNECT command. The hostname was invalid
3758 memory and server crashed. Affected file silcd/command.c.
3760 * Fixed fatal bug in CLOSE command. The server_entry became
3761 invalid but was referenced later in the command. Affected file
3764 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Fixed fatal bug in failure packet handling. Server ignored
3767 the failure and thus crashed when it came.
3771 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3774 that the command may be executed only once in (about) 2 seconds.
3775 The old SILC_CF_LAG flag is same but allows command bursts up
3776 to five before limiting.
3778 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3779 server code. Various commands now includes the CF_LAG_STRICT
3780 flag to disallow any kind of miss-use of the command.
3782 * Fixed the silc_buffer_unformat to not to allocate any data
3783 if the length of the data is zero. It used to allocate the
3784 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3786 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Changed the format of AdminConnection configuration section
3789 in the server. Added username of the admin to the format.
3790 Affected files silcd/serverconfig.[ch].
3792 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3793 to return admin configuration data by host, username and/or
3796 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Implemented WHOWAS command to the server. Added the functions:
3800 silc_server_command_whowas_parse,
3801 silc_server_command_whowas_send_reply,
3802 silc_server_command_whowas_from_client and
3803 silc_server_command_whowas_from_server
3805 * Added <Client ID> argument to the WHOWAS command reply. Updated
3806 the protocol specs accordingly.
3808 * Implemented WHOWAS command and command_reply to the client
3811 Implemented the WHOWAS printing on the user interface.
3813 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added new argument to the WHOWAS command reply, the real name.
3816 It is an optional argument. Updated the protocol specs.
3818 * Added SilcIDCacheDestructor callback that is registered when
3819 the SilcIDCache is allocated. The callback is called when
3820 an cache entry in the ID Cache expires, or is purged from the
3821 cache. Added into lib/silccore/idcache.[ch].
3823 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3824 to destruct the client entries when the cache entry expires.
3825 Other ID Cache's in server and in the client library ignores
3828 * If the ID Cache entry's `expire' field is zero then the entry
3829 never expires. Added boolean `expire' argument to the
3830 silc_idcache_add function in the lib/silccore/idcache.[ch].
3831 If it is TRUE the default expiry value is used.
3833 * Added silc_server_free_client_data_timeout that is registered
3834 when client disconnects. By default for 5 minutes we preserve
3835 the client entry for history - for WHOWAS command.
3837 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Added support to the server to enforce that commands are not
3840 executed more than once in 2 seconds. If server receives
3841 commands from client more frequently, timeout is registered
3842 to process the commands. Affected file silcd/command.c.
3843 Added new function silc_server_command_process_timeout.
3845 * Changed NICK_NOTIFY handling in client library to check that
3846 if the client's nickname was changed, so there is no need to
3847 resolve anything from the server.
3849 * Removed error printing from the WHOIS and IDENTIFY commands.
3850 If error occurs then it is ignored silently in the client library.
3851 The application, however, may map the received error to
3852 human readable error string. The application currently maps
3853 the NO_SUCH_NICKNAME error to string.
3855 * Made the command status message public to the application. Moved
3856 them from lib/silcclient/command_reply.c to
3857 lib/silcclient/command_reply.h. The application can map the
3858 received command status to the string with the
3859 silc_client_command_status_message function.
3861 * Added check to the server to check that client's ID is same
3862 as the Source ID in the packet the client sent. They must
3865 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added dist-bzip hook to the Makefile.am to make bzip2
3868 compressed distributions.
3870 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Server now enforces the maximum length for the nickname and
3873 the channel as protocol specification dictates. 128 bytes for
3874 nickname and 256 bytes for channel name.
3876 * Moved the WHOIS printing to the application. The client libary
3877 does not print out the WHOIS information anymore, the application
3878 must do it. Renamed silc_client_command_reply_whois_print to
3879 the silc_client_command_reply_whois_save.
3881 The client's idle time is also sent to the application now, and
3882 the idle is shown on screen.
3884 * Added silc_client_command_reply_identify_save to save the
3885 received IDENTIFY entries.
3887 * Do not check for channel private keys in message sending and
3888 reception if the channel does not have the PRIVKEY mode set.
3889 Affected file lib/silclient/client_channel.c.
3891 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3894 just surfaced after chaning the JOIN procedure.
3896 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Added silc_client_get_clients_by_list to get client entries
3899 from Client ID list, that is returned for example by JOIN
3900 and USERS command replies. The application should use this
3901 function for example when JOIN command reply is received to
3902 resolve the clients already on the channel (library does not
3903 do that anymore as USERS command reply is not used in the JOIN
3904 procedure anymore). Affected files lib/silcclient/silcapi.h and
3905 lib/silcclient/idlist.c.
3907 * JOIN command reply and USERS command reply returns now SilcBuffer
3908 pointers instead of unsigned char pointers when returning
3909 the client list and mode list.
3911 * Added <Client ID> argument to the JOIN command reply, mainly
3912 for the server to identify for which client the command was
3913 originally sent. Updated protocol specs accordingly.
3915 * Added SilcDlist private_key pointer to the SilcChannelEntry
3916 in the client to support the channel private keys. Affected
3917 file is lib/silcclient/idlist.h.
3919 * Added SilcChannelPrivateKey argument to the function
3920 silc_client_send_channel_message so that application can choose
3921 to use specific private ke if it wants to. If it is not provided,
3922 the normal channel key is used, unless private keys are set.
3923 In this case the first (key that was added first) is used
3924 as the encryption key.
3926 * Implemented the support for channel private key handling.
3927 Implemented the following functions:
3929 silc_client_add_channel_private_key,
3930 silc_client_del_channel_private_keys,
3931 silc_client_del_channel_private_key,
3932 silc_client_list_channel_private_keys and
3933 silc_client_free_channel_private_keys
3935 Affected file lib/silcclient/client_channel.c.
3937 * Added the support for the private keys in the channel message
3938 sending and encryption and in the message reception and
3939 decryption. Affected funtions are
3940 silc_client_send_channel_message and silc_client_channel_message.
3942 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Added SKE's key verify callback to the client library's
3945 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3947 * Removed the statement that server (or router) must send USERS
3948 command reply when joining to the channel so that the client
3949 knows who are on the channel. Instead, the client list and
3950 client's mode list is now sent in the JOIN command reply to the
3951 client who joined channel. This is better solution.
3953 * Added function silc_server_get_users_on_channel and function
3954 silc_server_save_users_on_channel to the silcd/server.[ch].
3956 * Removed function silc_server_command_send_users from the
3959 * Do not show topic on the client library anymore. The topic is
3960 sent in the command reply notify to the application and the
3961 application must show the topic now.
3963 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Added client searching by nickname hash into the IDENTIFY and
3966 WHOIS commands in the server as they were clearly missing from
3967 them. Affected file is silcd/command.c.
3969 * Fixed a bug in private message receiving in the client library.
3970 The remote ID was freed and it wasn't supposed, now it is
3973 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Minor fix to the channel payload; allocate the data area, as it
3976 needs to be of specific length.
3978 * If the key agreement port is zero then the operating
3979 system will define the bound port. Affected files are
3980 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3982 * Added new function silc_channel_payload_decrypt into the file
3983 lib/silccore/silcchannel.[ch].
3985 * Moved the channel message etc, check from silc_packet_decrypt
3986 to applications. The library calls now a generic
3987 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3988 when the packet is either normal or special. This was done to
3989 allow more wide range of checking that was not allowed when
3990 the code was in library. Now applications can do virtually any
3991 checks to the packet and return to the library the decision how
3992 the packet should be processed. Affected files are
3993 lib/silccore/silcpacket.[ch].
3995 Added silc_server_packet_decrypt_check to the server and
3996 silc_client_packet_decrypt_check to the client library.
3998 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3999 to send with specified source and destination information.
4001 * Channel message delivery between routers was broken after the
4002 channel key distribution was fixed earlier. The channel key
4003 was used be to distributed to other routers as well which is not
4004 allowed by the protocol. Now this is fixed and channel keys
4005 really are cell specific and the channel message delivery between
4006 routers comply with the protocol specification.
4008 * Fixed various commands in server to check also the global list
4009 for the channel entry and not just the local list. The affected
4010 file silcd/command.c.
4012 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Added assert()s to buffer formatting and unformatting routines
4015 to assert (if --enable-debug) when error occurs. Affected
4016 file: lib/silcutil/silcbuffmt.c.
4018 * Changed to auto-reconnect to check whether the remote host is
4019 router and register the re-connect timeout if it is. It used
4020 to check that whether we are normal server, but router must do
4021 auto-reconnect with another router as well. Affected file
4024 * Removed the [<key len>] option from CMODE command as the cipher
4025 name decides the key length, nowadays. See the defined ciphers
4026 from the protocol specification.
4028 * Added [<hmac>] option to the CMODE command to define the HMAC
4029 for the channel. Added SILC_CMODE_HMAC channel mode.
4031 * Added [<hmac>] option for the JOIN command so that user can
4032 select which HMAC is used to compute the MACs of the channel
4035 * Added Hmac field to the Channel Message Payload. The integrity
4036 of plaintext channel messages are now protected by computing
4037 MAC of the message and attaching the MAC to the payload. The
4038 MAC is encrypted. Now, it is clear that this causes some
4039 overhead to the size of the packet but rationale for this is that
4040 now the receiver can verify whether the channel message decrypted
4041 correctly and also when private keys are set for the channel the
4042 receiver can decrypt the packet with several keys and check from
4043 the MAC which key decrypted the message correctly.
4045 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4046 lib/silccrypt/silccipher.[ch].
4048 * Added silc_hash_len to return the digest length into the
4049 lib/silcrypt/silchash.[ch].
4051 * Rewrote parts of Silc Channel Payload interface in the
4052 lib/silccore/silcchannel.[ch]. The encode function now also
4053 encrypts the packet and parse function decrypts it.
4055 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Fixed a minor formatting bug in the SKE's key material processing.
4058 It actually might have processed the keys wrong way resulting
4061 * Redefined the mandatory HMAC algorithms and added new algorithms.
4062 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4063 and hmac-md5 truncated to 96 bits. The mandatory is now
4064 hmac-sha1-96. Rest are optional (including the one that used
4065 to be mandatory). Rationale for this is that the truncated HMAC
4066 length is sufficient from security point of view and can actually
4067 make the attack against the HMAC harder. Also, the truncated
4068 HMAC causes less overhead to the packets. See the RFC2104 for
4071 * Added new [hmac] configuration section. The SKE used to use
4072 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4073 is of course wrong. The official names that must be proposed in
4074 the SKE are the ones defined in the protocol specification
4075 (hmac-sha1-96 for example). The user can configure any hmac
4076 using any hash function configured in the [hash] section. At
4077 least, the mandatory must be configured.
4079 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4081 * Added HMAC list to the SKE proposal list. It has now both
4082 hash algorithm list and HMAC list. This makes the protocol
4083 incompatible with previous versions. The SKE now seems to work
4084 the way it is supposed to work, for the first time actually.
4086 * Defined plain Hash algorithms to the protocol specification.
4089 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Implemented support for key agreement packets into the server.
4092 Added functions silc_server_key_agreement and
4093 silc_server_send_key_agreement. Other than these functions,
4094 server has nothing to do with this packet.
4096 * Added support for private message key packets into the server.
4097 Added functions silc_server_private_message_key and
4098 silc_server_send_private_message_key.
4102 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4103 called in the protocol's final callback instead in the END
4104 protocol state. This makes a little more sense and in the same
4105 time in client we can use the same protocol routines for normal
4106 key exchange and to key agreement packet handling as well.
4108 * Added to both client's and server's KE protocol context the
4109 SilcSKEKeyMaterial pointer to save the key material. We will
4110 bring the key material to the protocol's final callback by doing
4111 this. The final callback must free the key material.
4113 * Added SKE's packet_send callback into client's KE protocol
4114 context so that the caller can choose what packet sending function
4115 is used. This way we can use different packet sending when
4116 doing normal SKE when doing key agreement packet handling (in
4117 the key agreement packet handling we do not want to encrypt
4120 * Implemented the responder side of the key agreement routines
4121 in the client. The client can now bind to specified port and
4122 accept incoming key negotiation. The key material is passed
4123 to the application after the protocol is over.
4125 * Implemented the processing of incoming Key Agreement packet
4126 in the client. Added function silc_client_key_agreement to
4129 * Implemented the intiator side of the key agreement routines
4130 in the client. The client can now initiate key agreement with
4131 another remote client. The key material is passed to the
4132 application after the protocol is over.
4134 * Created client_keyagr.c to include all the key agreement
4137 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4138 SILC_TASK_CALLBACK except that it is not static.
4140 * Created client_notify.c and moved the Notify packet handling
4141 from the client.[ch] into that file.
4143 * Created client_prvmsg.c and moved all private message and
4144 private message key routines from the client.[ch] into that file.
4146 * Create client_channel.c and moved all channel message and
4147 channel private key routines from the client.[ch] into that file.
4149 * Changed silc_client_get_client_by_id_resolve to resolve with
4150 WHOIS command instead of IDENTIFY command, in the file
4151 lib/silclient/idlist.c.
4153 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Implemented the SKE's responder side to the Client library.
4157 * When FAILURE is received to the protocol do not trust it
4158 blindly. Register a timeout to wait whether the remote closes
4159 the connection as it should do it, only after that process the
4160 actual failure. This was changed to both client and server.
4162 * Added client_internal.h to include some of the structures
4163 there instead of client.h in lib/silcclient/.
4165 * Added function silc_task_unregister_by_callback to unregister
4166 timeouts by the callback function.
4168 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Some "Incomplete WHOIS info" errors has been appearing on the
4171 log files. Took away the entry->userinfo check from WHOIS
4172 reply sending. The entry->userinfo is now " " if client did not
4173 provide one. I thought this was fixed earlier but something
4174 is wrong still. Let's see if the error still appears.
4176 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Fixed a minor bug in the login when the channel key is
4179 re-generated in the server. It used to generate the key in
4180 wrong order and thus caused problems in the channel traffic.
4182 * Fixed a minor bug in channel key distsribution after
4183 KICK command. The key was not sent to the router even though
4186 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Added silc_ske_process_key_material_data as generic routine
4189 to process any key material as the SILC protocol dictates. The
4190 function is used by the actual SKE library but can be used by
4191 applications as well. This relates to the private message keys
4192 and the channel private keys since they must be processed the
4193 same way the normal SILC session keys. The protocol dictates
4194 this. Affected files: lib/silcske/silcske.[ch].
4196 Added also silc_ske_free_key_material to free the
4197 SilcSKEKeyMaterial structure.
4199 * Defined silc_cipher_set_key function to set the key for
4200 cipher without using the object's method function. The affected
4201 files: lib/silccrypt/silccipher.[ch].
4203 * Implemented silc silc_client_add_private_message_key,
4204 silc_client_add_private_message_key_ske,
4205 silc_client_del_private_message_key,
4206 silc_client_list_private_message_keys and
4207 silc_client_free_private_message_keys functions in the
4210 Added functions silc_client_send_private_message_key to send
4211 the Private Message Key payload and silc_client_private_message_key
4212 to handle incoming Private Message Key payload.
4214 * Added Cipher field to the Private Message Key payload to set
4215 the cipher to be used. If ignored, the default cipher defined
4216 in the SILC protocol (aes-256-cbc) is used.
4218 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Removed lib/silcclient/ops.h file.
4222 Redefined parts of the SILC Client Library API. Created new
4223 file silcapi.h that deprecates the ops.h file and defines the
4224 published Client Library API. Defined also private message key
4225 API and channel private key API into the file.
4227 This is the file that the application must include from the
4228 SILC Client Library. Other files need not be included by
4229 the application anymore.
4231 * Added new key_agreement client operation callback and also
4232 defined the Key Agreement library API for the application.
4234 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4237 is used by clients to request key negotiation between another
4238 client in the SILC network. If the negotiation is started it
4239 is performed using the SKE protocol. The result of the
4240 negotiation, the secret key material, can be used for example
4241 as private message key.
4243 Implemented the Key Agreement payload into the files
4244 lib/silccore/silauth.[ch].
4246 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Redefined ciphers for the SILC protocol. Added some new ciphers
4249 and defined the key lengths for the algorithms. Changed the
4250 code accordingly. The default key length is now 256 bits.
4252 * Fixed SKE key distribution function silc_ske_process_key_material
4253 when the key length is more than 128 bits. The default key
4254 length in SILC is now 256 bits.
4256 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4257 to indicate unsupported algorithm.
4259 * Renamed rijndael.c to aes.c and all functions as well.
4261 * Fixed a long standing channel key setting bug in client library.
4262 Weird that it has never surfaced before.
4264 * Fixed bug in channel deletion. If the entire channel is removed
4265 then it must also delete the references of the channel entry
4266 from the client's channel list as the client's channel entry and
4267 the channel's client entry share same memory.
4269 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Implemented CONNECT and SHUTDOWN commands in the client.
4273 * Implemented CLOSE command to the client.
4275 * Added the function silc_idlist_find_server_by_name into the
4276 files silcd/idlist.[ch].
4278 Added the function silc_idlist_find_server_by_conn into the
4279 files silcd/idlist.[ch].
4281 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * DIE command was renamed to SHUTDOWN. Updated the both code
4286 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4287 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4289 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4292 * Added function silc_server_create_connection function to create
4293 connection to remote router. My server implementation actually
4294 does not allow router to connect to normal server (it expects
4295 that normal server always initiates the connection to the router)
4296 so the CONNECT command is only good for connecting to another
4299 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4302 or some other client was kicked from the channel.
4304 Implemented the handling of the notify type to both client
4307 Implemented silc_server_send_notify_kicked to send the KICKED
4308 notify. It is used to send it to the server's primary router.
4310 * Implemented the KICK command into server and client.
4312 * Added `query' argument to the silc_idlist_get_client function
4313 to indicate whether to query the client from server or not if
4316 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4317 to indicate that the client is not channel founder.
4321 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Removed the rng context from SilcPacketContext structure and
4324 changed that the packet routine uses the Global RNG API.
4326 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Added support for quit message that client can "leave" on the
4329 channel when it quits the SILC. It is ditributed inside the
4330 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4332 Added silc_server_free_client_data that will take the
4333 signoff message as argument.
4335 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4337 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Updated parts of the protocol specification to keep it up
4342 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4345 payloads in one packet.
4347 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4348 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4349 use now the new List flag.
4351 * Also deprecated the following packet types: REPLACE_ID,
4352 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4354 * Added list support for Notify packet in server.
4356 * Added silc_server_send_notify_channel_change to send the
4357 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4358 the silc_server_send_replace_id.
4360 * Added silc_server_send_notify_nick_change to send the
4361 NICK_CHANGE notify type. Deprecates the function
4362 silc_server_send_replace_id.
4364 * Added silc_server_send_notify_join to send the JOIN notify type.
4365 Deprecates the function silc_server_send_new_channel_user.
4367 * Added silc_server_send_notify_leave to send LEAVE notify type.
4368 Deprecates the function silc_server_send_remove_channel_user.
4370 * Added silc_server_send_notify_cmode and
4371 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4372 types. Deprecates the silc_server_send_set_mode function.
4374 * Added SERVER_SIGNOFF notify type to indicate that server has
4375 quit. This means that all clients on the channel from that
4376 server will drop. This can be also used when netsplit happens.
4378 Deprecated REMOVE_ID packet type since it is not needed anymore
4381 Added silc_server_send_notify_server_signoff to send the
4382 SERVER_SIGNOFF notify type. Deprecates the function
4383 silc_server_send_remove_id.
4385 Added also silc_server_send_notify_signoff to send the
4386 SIGNOFF notify type.
4388 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4389 SILC protocol from this day on. Changed the protocol
4390 specification as well.
4392 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4393 notify type. It is used between routers to notify about
4394 topic changes on a channel.
4396 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4399 * Partly updated the protocol specification to comply with the
4400 changes now made. It is still though a bit outdated.
4402 * The JOIN notify type now takes one extra argument <Channel ID>.
4403 The packet used to be destined to the channel but now the
4404 JOIN type may be sent as list thus it is impossible to
4405 destine it to any specific channel. By adding this argument
4406 it is again possible.
4408 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Added CREDITS file. The CHANGES and CREDITS file will appear
4411 in the distribution as well.
4413 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4416 types in the server's silcd/packet_receive.c.
4418 * Implemented CMODE and CUMODE to work in router environment.
4420 * Fixed minor encoding and decoding buglet from the
4421 lib/silccore/silcmode.c.
4423 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4426 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4428 * Changed all SilcConfigServer* and silc_config_server* to
4429 SilcServerConfig* and silc_server_config*, respectively.
4432 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Associated the ID (client or server ID) to the Authentication
4435 Payload to avoid any possibility of forging. Updated the
4436 protocol specification and the code accordingly.
4438 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * The RSA key length is now save to the RsaKey context in the
4441 key generation process in lib/silccrypt/rsa.c. The key length
4442 is now used to figure out the maximum size of the block allowed
4443 to be encrypted/signed.
4445 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4446 is equivalent to the silc_mp_mp2bin but does not allocate any
4449 * Changed silc_mp_mp2bin API to take length argument. If it is
4450 non-zero then the buffer is allocated that large. If zero, then
4451 the size is approximated using silc_mp_sizeinbase, which however
4454 * Created Global RNG API which is global RNG that application can
4455 initialize. After initializing, any routine anywhere in the
4456 code (including library) can use RNG without allocating a new
4457 RNG object. This was done to allow this sort of use of the
4458 RNG in code that has no chance to allocate RNG object. All
4459 applications currently allocate this and many routines in the
4460 library use this. Affected file lib/silccrypt/silcrng.[ch].
4462 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4463 it to use the Global RNG API.
4465 * Defined Authentication Payload into protocol specification that
4466 is used during SILC session to authenticate entities. It is
4467 used for example by client to authenticate itself to the server
4468 to obtain server operator privileges.
4470 Implemented this payload into the lib/silccore/silcauth.[ch].
4471 Implemented also routines for public key based authentication
4472 as the new protocol specification dictates.
4474 Moved definitions of different authentication methods from
4475 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4477 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4478 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4479 silc_pkcs_verify_with_hash functions into the file
4480 lib/silccrypt/silcpkcs.[ch].
4482 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * The client entry's userinfo pointer must be always valid.
4485 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4486 will fail since it requires the userinfo. Now, the userinfo
4487 is allocated as "" if actual userinfo does not exist. Actually,
4488 it must exist and it is totally Ok to drop client connections
4489 that does not announce the userinfo. However, we will make
4490 this workaround for now.
4492 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4493 to return the remote port by socket.
4495 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4498 SILC_SERVER_PENDING_EXEC and added an new macro
4499 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4500 data or when error occurs while processing the pending command.
4502 Added new argument `destructor' into silc_server_command_pending
4503 and to the SilcServerCommandPending object. This destructor is
4504 now called after calling the pending callback or if error occurs
4505 immediately. If error occurs the actual pending callback won't
4506 be called at all - only the destructor. The destructor may be
4507 NULL if destructor is not needed.
4509 All this applies for client library code as well. Similar
4510 changes were made there as well for the pending commands.
4512 In the client, the application must now allocate the
4513 SilcClientCommandContext with the silc_client_command_alloc
4516 * Added reference counter to the SilcServerCommandContext. Added
4517 function silc_server_command_alloc and silc_server_command_dup
4520 Same type of functions added to the client library for the same
4523 * Removed the cmd_ident from IDListData away since it is now
4524 global for all connections. It is the command identifier used
4525 in command sending and with pending commands. The affected file
4528 * Added reference counter to the SilcSocketConnection objecet to
4529 indicate the usage count of the object. The object won't be
4530 freed untill the reference counter hits zero. Currently only
4531 server uses this, and client ignores it. The client must be
4532 set to use this too later. The affected files are
4533 lib/silccore/silcsockconn.[ch]. Added also the function
4534 silc_socket_dup to increase the reference counter.
4536 This was mainly added because it is possible that the socket
4537 is removed underneath of pending command or other async
4538 operation. Now it won't be free'd and proper DISCONNECTING
4539 flags, etc. can be set to avoid sending data to connection that
4540 is not valid anymore.
4542 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4543 the connection. After that it sets SILC_SET_DISCONNECTED.
4544 It is, however, possible that the socket data is not still freed.
4545 The silc_server_packet_process now checks that data is not
4546 read or written to connection that is DISCONNECTED. The socket
4547 get's freed when the reference counter hits zero.
4549 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Changed the client operation API: channel_message operation's
4552 `sender' is now the client entry of the sender, not the nickname
4553 and the `channel' is the channel entry, not the channel name.
4555 In the private_message operation the `sender' is now also the
4556 client entry of the sender not the nickname.
4558 Affected file is lib/silcclient/ops.h and all applications
4559 using the client operations.
4561 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Moved the calling of ops->connect() from connect_to_server_final
4564 into receive_new_id functin since that is the point when the
4565 client is actually allowed to send traffic to network. The
4566 affected file is lib/silcclient/client.c.
4568 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4571 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4572 (if needs broadcasting) instead of broadcasting the packets one
4573 by one which would make a burst in the network traffic.
4575 * Added `broadcast' argument to the functions in silcd/server.[ch]
4576 silc_server_create_new_channel[_with_id] to indicate whether
4577 to send New Channel packet to primary router.
4579 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added new function into the silcd/server.[ch] files:
4582 silc_server_create_new_channel_with_id to create new channel with
4583 already existing Channel ID.
4585 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4586 lib/silccore/silcpacket.h. This packet is used t send list of
4587 Set Mode payloads inside one packet. Server uses this to set
4588 the modes for the channels and clients on those channels, that it
4589 announced to the router when it connected to it. The protocol
4590 specification has been updated accordingly.
4592 * The silc_server_new_channel did not handle the packet coming
4593 from normal server as it normally does not send that. However,
4594 when it announces its channels it does send it. Implemented
4595 the support for that.
4597 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4598 into the file lib/silccore/id.h.
4600 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Fixed memory leaks in the functions silc_idlist_del_client,
4603 silc_idlist_del_channel and silc_idlist_del_server in the file
4604 silcd/idlist.c. All of those leaked like a sieve.
4606 * Fixed some small memory leaks in the client's function
4607 silc_client_notify_by_server.
4609 * Added functions into silcd/server.c: silc_server_announce_clients,
4610 silc_server_announce_channels and silc_server_announce_server.
4611 These functions are used by normal and router server to announce
4612 to its primary router about clients, channels and servers (when
4613 router) that we own. This is done after we've connected to the
4616 These functions effectively implements the following packet types:
4617 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4618 and SILC_PACKET_NEW_ID_LIST.
4620 * Added new functions into the silcd/packet_receive.[ch]:
4621 silc_server_new_id_list, silc_server_new_channel_list and
4622 silc_server_new_channel_user_list to handle the incoming
4623 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4625 * Added support of changing Channel ID in the function
4626 silc_server_replace_id. If the server that announces a channel
4627 to the router already exists in the router (with same name but
4628 with different Channel ID), router is responsible to send
4629 Replace ID packet to the server and force the server to change
4630 the Channel ID to the one router has.
4632 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4633 client that the Channel ID has been changed by the router. The
4634 normal server sends this to the client. Client must start using
4635 the new Channel ID as the channel's ID.
4637 Implemented handling of this new type into lib/silcclient/client.c
4638 into the function silc_client_notify_by_server.
4640 * Added new function silc_idlist_replace_channel_id into the files
4641 silcd/idlist.[ch] to replace the Channel ID.
4643 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Call silc_server_command_identify_check always when processing
4646 the IDENTIFY command in silcd/command.c
4648 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4651 send keepalive packets. The packet can be sent by clients,
4652 servers and routers.
4654 Added function silc_socket_set_heartbeat into the file
4655 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4656 If not set, the heartbeat is not performed. The actual
4657 heartbeat is implemented in the low level socket connection
4658 library. However, application is responsible of actually
4661 Added silc_server_send_heartbeat to send the actual heartbeat
4662 packet into silcd/packet_send.[ch]. Server now performs
4663 keepalive with all connections.
4665 * Added silc_task_get_first function into lib/silcutil/silctask.c
4666 to return the timeout task with shortest timeout. There was a bug
4667 in task unregistration that caused problems. TODO has been
4668 updated to include that task system must be rewritten.
4670 * The client library will now resolve the client information when
4671 receiving JOIN notify from server for client that we know but
4672 have incomplete information.
4674 * Rewrote parts of silc_server_remove_from_channels and
4675 silc_server_remove_from_one_channel as they did not remove the
4676 channel in some circumstances even though they should've.
4678 * Encryption problem encountered in server:
4680 The LEAVE command used to send the Channel Key packet to the
4681 router immediately after generating it. However, the code
4682 had earlier sent Remove Channel user packet but not immediately,
4683 ie. it was put to queue. The order of packets in the router
4684 was that Channel Key packet was first and Remove Channel User
4685 packet was second, even though they were encrypted in the
4686 reverse order. For this reason, MAC check failed. Now, this
4687 is fixed by not sending the Channel Key packet immediately but
4688 putting it to queue. However, this is more fundamental problem:
4689 packets that are in queue should actually not be encrypted
4690 because packets that are sent immediately gets encrypted
4691 actually with wrong IV (and thus MAC check fails). So, packets
4692 that are in queue should be encrypted when they are sent to
4693 the wire and not when they put to the queue.
4695 However, the problem is that the current system has not been
4696 designed to work that way. Instead, the packet is encrypted
4697 as soon as possible and left to the queue. The queue is then
4698 just purged into wire. There won't be any fixes for this
4699 any time soon. So, the current semantic for packet sending
4702 o If you send packet to remote host and do not force the send
4703 (the packet will be in queue) then all subsequent packets to the
4704 same remote host must also be put to the queue. Only after the
4705 queue has been purged is it safe again to force the packet
4708 o If you send all packets immediately then it safe to send
4709 any of subsequent packets through the queue, however, after
4710 the first packet is put to queue then any subsequent packets
4711 must also be put to the queue.
4713 Follow these rules and everything works fine.
4715 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Added new function silc_server_remove_clients_by_server to
4718 remove all client entries from ID list when the server connection
4719 is lost. In this case it is also important to invalidate all
4720 client entires as they hold the invalid server entry. This
4721 fixes fatal bug when server has lost connection and will reconnect
4724 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Made some sanity checks to silc_server_daemonise like to check
4727 whether the requested user and group actually exists.
4729 * Added sanity check to SKE's silc_ske_responder_finish to check
4730 that the public and private key actually is valid.
4732 * Invalidate the client's nickname when receiving Replace ID
4733 packet and the Client ID is being replaced. This means that the
4734 server will query the nickname if someone needs it (client)
4737 * Sort the ID Cache in client library when the ID Cache data
4738 has changed (needs sorting).
4740 * Do not allow for SILC client to create several connections to
4741 several servers. The client does not support windows right now
4742 and generating multiple connections causes weird behaviour.
4744 Irssi-silc client does support windows and can handle several
4745 connections without problems, see: www.irssi.org and SILC plugin.
4747 * Fixed some places where client was added to the IDList. The
4748 rule of thumb is following (in order to get everything right):
4749 If the client is directly connected local client then the
4750 `connection' argument must be set and `router' argument must be
4751 NULL to silc_idlist_add_client function. If the client is not
4752 directly connected client then the `router' argument must
4753 bet set and the `connection' argument must be NULL to the
4754 silc_idlist_add_client function.
4756 * The funtion silc_server_packet_send_local_channel actually did
4757 not check whether the client was locally connected or not. It
4758 does that now. Fixed a bug related to LEAVE command.
4760 * Fixed Remove Channel User payload parsing bug in server's
4761 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4763 * The server's silc_server_save_channel_key now checks also the
4764 global ID list for the channel as it might not be in the local
4765 list. Fixed a bug related to LEAVE command.
4767 * Is this the end of the [<unknown>] buglet that has been lurking
4768 around for a long time? A little for loop fix in server's
4769 silc_server_command_whois_parse that is used by both IDENTIFY
4770 and WHOIS command. At least, this was a clear bug and a cause
4771 of one type of [<unknown>] buglet.
4773 * WHOIS and IDENTIFY commands call the function
4774 silc_server_command_[whois/identify]_check function even if
4775 we are not router server.
4777 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added --with-gmp configuration option. If set the GMP
4780 is always compiled in the SILC source tree. If not set then
4781 it is checked whether the system has the GMP3 installed. If
4782 it has then the GMP won't be compiled (the system's headers
4783 and library is used), if it doesn't have it then the GMP is
4784 compiled in the SILC source tree.
4786 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Changed RSA private exponent generation to what PKCS #1
4789 suggests. We try to find the smallest possible d by doing
4790 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4791 not security fix but optimization.
4793 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Added new config entry [Identity] to fork the server and run
4796 it as specific user and group. A patch from Bostik.
4798 * Imported Dotconf configuration library into lib/dotconf.
4799 This will be used to create the SILC configuration files later.
4800 It will appear in the distsribution after this commit.
4802 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * A big code auditing weekend happening. Auditing code for
4805 obvious mistakes, bugs and errors. Also, removing any code
4808 Removed files for being obsolete:
4810 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4811 inline in the file lib/silcutil/silcbuffer.h)
4813 o lib/silcutil/silcbufutil.c (the header has inline versions)
4815 Changed code to fix possible error conditions:
4817 o The buffer formatting routines now check that the destination
4818 buffer really has enough space to add the data. This applies for
4819 both buffer formatting and unformatting
4820 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4821 unformatting was changed to accomodate following rules:
4822 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4823 sent to the function while XXX_*STRING will not allocate or copy
4824 the data into the buffer. Instead it sets the pointer from the
4825 buffer into the pointer sent as argument (XXX_*STRING used to
4826 require that the pointer must be allocated already). This change
4827 makes this whole thing a bit more consistent and more optimized
4828 (note that the data returned in the unformatting with XXX_*STRING
4829 must not be freed now). The routines return now -1 on error.
4831 o Tried to find all code that use buffer_format and buffer_unformat
4832 and added return value checking to prevent formatting and
4833 especially unformatting errors and possible subsequent fatal
4836 o Changed ske->x and ske->KEY to mallocated pointers in
4837 lib/silcske/silcske.h. Fixed possible data and memory leak.
4839 o Added return value checking to all *_parse* functions. Fixed
4840 many memory leaks as well.
4842 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4843 so that buffer overflows would not happen. All code now also
4844 checks the return value as it can fail.
4846 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Added reconnection support to server if the normal server looses
4849 its connection to the router (for example if router is rebooted).
4850 The server performs normal reconnection strategy implemented
4851 to the server. Affected file silcd/server.c.
4853 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Added new packet type SILC_PACKET_SET_MODE that is used to
4856 distribute the information about changed modes (for clients,
4857 channels and clients channel modes) to all routers in the
4858 network. Updated the protocol specification accordingly.
4860 Added functions into silcd/packet_send.c and
4861 silcd/packet_receive.c: silc_server_send_set_mode,
4862 silc_server_set_mode.
4864 Added new files silcmode.[ch] into lib/silccore that implements
4865 the encoding and decoding of Set Mode Payload. Added new type
4866 SilcSetModePayload. Moved the definitions of different modes
4867 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4869 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Oops, a little mistake in server's connection authentication
4872 protocol. The protocol is not ended with FAILURE but with
4873 SUCCESS if the authentication is Ok. :) Affected file is
4876 * Implemented NICK_CHANGE notify handling in server in the file
4877 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4878 the local clients on the channel. After the changing nickname
4879 in router environment snhould work and the [<unknown>] nickname
4880 should appear no more.
4882 The silc_server_replace_id function that receives the Replace ID
4883 payload now sends the NICK_CHANGE notify type also in the file
4884 silcd/packet_receive.c
4886 * Changed WHOIS and IDENTIFY command to support the maximum amount
4887 of arguments defined in protocol specs (3328 arguments). This
4888 fixed a bug that caused problems when there were more than three
4891 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Added extra parameter, command identifier, to the
4894 silc_client_send_command so that explicit command identifier
4897 Changed that ID list routines uses specific command identifier
4898 when sending WHOIS/IDENTIFY requests to the server so that they
4899 can be identified when the reply comes back.
4901 Affected files lib/silcclient/command.[ch],
4902 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4904 * Added `sender' argument to silc_server_packet_send_to_channel
4905 to indicaet the sender who originally sent the packet to us
4906 that we are now re-sending. Ignored if NULL. Affected file
4907 silcd/packet_send.[ch].
4909 * Added some server statistics support in silcd/server_internal.h
4910 SilcServerStatistics structure and around the server code. Also
4911 send some nice statistics information when client is connecting
4914 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Fixed channel ID decoding in server's JOIN command reply in
4917 silcd/command_reply.c
4919 * Fixed braodcasting of replace ID payload to not to send it if
4920 we are standalone server in silcd/packet_receive.c.
4922 * Fixed all channel message sending routines to not to send
4923 packets to clients that has router set, since they are routed
4924 separately in the same function earlier. Affects file
4925 silcd/packet_send.c and all channel packet sending functions.
4927 * In USERS reply, res_argv[i] are not allocated, the table
4928 is allocated. Thus changed that free the table, not its
4931 * In server's whois_check and identify_check if the client is
4932 locally connected do not send any WHOIS commands - they are not
4935 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed some minor bugs in client when sending WHOIS command. The
4938 arguments was in wrong order.
4940 * Removed statis function add_to_channel from server in
4941 silcd/command.c that was previously used with the joining but
4944 * Tested USERS command in router environment successfully with two
4945 routers, two servers and two clients.
4947 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Reorganized the USERS command and command reply in client library
4950 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4951 When the command is given by user we register a pending command
4952 callback that will reprocess the command after the reply has been
4953 received from the server. When reprocessing the packet we then
4954 display the information. Thus, the USERS information is displayed
4955 now in the command callback instead of in the command reply
4956 callback. The processing of the command is same as previously
4957 when server has sent the command reply in the JOINing process.
4959 * Added to USERS command in silcd/command_reply.c to join the client,
4960 we didn't use to know about, to the channel after we've created
4961 a client entry for it. Also, for clienet we did know already still
4962 check whether it is on the channel or not and add it if not.
4964 * Removed silc_server_command_join_notify as the function and its
4967 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Changed the client's pending command handling to the same as the
4970 server's pending command handling. It is also now possible to
4971 execute command reply functions from other command reply
4972 function as the function callbacks for commands and command
4973 replies are one and same. The pending commands are not static
4974 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4975 in client connection context. Thus, pending commands are server
4976 connection specific as it is convenient.
4978 Changed the function silc_client_command_pending and
4979 silc_client_command_pending_del and added new function
4980 silc_client_command_pending_check. Removed the
4981 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4984 * Added cmd_ident, current command identifier, to the client
4985 connection context in lib/silcclient/client.h to keep track on
4986 command identifiers used in command sending. Client's command reply
4987 function handling now supports the mandatory command identifiers.
4989 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4990 funtions in client to fully support pending command callbacks.
4992 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4993 as one of the arguments to the application in the command reply
4996 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4997 before first releasing SILC but came back. Now it is removed again
4998 and should come back nomore. The FORWARDED flag was used only
4999 by the JOINing procedure by forwarding the command packet to router.
5000 Now, the JOINing procedure has been changed to more generic (due
5001 to various router environment issues) and FORWARDED is not needed
5002 anymore for anything. The protocol specification is yet to be
5005 Now, removed silc_server_packet_forward from server and the flag
5006 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5008 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Renamed NAMES command to USERS command. The NAMES was named that
5011 due to historical reasons. Now it is renamed. Also, rewrote
5012 parts of the USERS command. The nickname list is not sent anymore
5013 by the server. Only Client ID and mode lists are sent in the USERS
5014 command. Changed this also to the protocol specification.
5016 The client now resolves the names and stuff after it receives
5017 the USERS list from the server when joining to the channel.
5019 * WHOIS and IDENTIFY commands has been changed to support multiple
5020 Client ID's per command. One can now search for multiple users
5021 in the network by sending only one WHOIS or IDENTIFY command.
5022 Changed the code and the protocol specifications.
5024 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5025 uses silc_server_command_whois_parse to parse the request. */
5027 * If normal server, do not parse the WHOIS and IDENTIFY requests
5028 before sending it to the router. Saves some time.
5030 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Fixed JOIN command on client library. Wrong number of arguments
5033 used to crash the client.
5035 * Added silc_server_channel_has_global function to check whether
5036 channel has global users or not.
5038 * Added silc_server_channel_has_local function to check whether channel
5039 has locally connected clients on the channel.
5041 * The silc_server_remove_from_one_channel now checks whether the
5042 channel has global users or not after given client was removed from
5043 the channel. It also checks whether the channel has local clients
5044 on the channel anymore. If it does not have then the channel entry
5045 is removed as it is not needed anymore.
5047 * The silc_server_notify now checks on JOIN notify whether the joining
5048 client is one of locally connected or global. If it is global then
5049 the channel has now global users on the channel and that is marked
5050 to the channel entry. Also, it now saves the global client to
5051 global list who is joining and JOINs it to the channel. This is
5052 for normal server, that is.
5054 Changed silc_server_send_notify_on_channel,
5055 silc_server_packet_relay_to_channel and
5056 silc_server_packet_send_to_channel check if we are normal server
5057 and client has router set (ie. global client) do not send the
5058 message to that client, as it is already routed to our router.
5060 * Implemented LEAVE notify type handling in silc_server_notify
5063 * Tested LEAVE command in router environment successfully. Tested
5064 with two routers, two servers and two clients.
5068 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5070 * Implemented SIGNOFF notify type handling in silc_server_notify
5073 * silc_server_remove_id now removes the client entry from all channels
5074 it has joined and thusly sends SIGNOFF notify type.
5076 * Rewrote the NAMES list generation in server by removing two excess
5077 loops. The lists are created now inside one loop.
5079 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * silc_server_remove_channel_user checks now also global list
5082 for channel and client.
5084 * silc_server_new_channel_user checks now both local and global
5085 list for channel and client. Fixed a bug in client id decoding.
5086 Used to decode wrong buffer.
5088 * silc_server_channel_message checks now both local and global
5089 list for channel entry.
5091 * Tested channel joining (hence JOIN) in router environment
5092 successfully. Tested with two routers, two servers and two
5095 * Tested channel message sending in router environment successfully.
5097 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Added silc_server_save_channel_key into server.[ch] to save the
5100 received channel key in Channel Key payload processing. It is
5101 also used in JOIN command reply handling.
5103 Equivalent function silc_client_save_channel_key added into
5104 client.[ch] into client library.
5106 * Changed JOIN command reply to send information whether the channel
5107 was created or not (is existing already) and the channel key
5108 payload. Changed protocol specs accordingly.
5110 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5111 the request was sent by ID and not by nickname. Crashed on
5114 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5117 now correctly save the received data.
5119 * silc_server_free_sock_user_data now notifies routers in the
5120 network about entities leaving the network.
5122 At the same time implemented functions silc_server_remove_id
5123 and silc_server_send_remove_id to receive and send REMOVE_ID
5124 packets. The packet is used to notify routers in the network
5125 about leaving entities. The ID removed will become invalid in
5128 * Added function silc_idlist_del_server into server. Removes and
5129 free's server entry from ID list.
5131 * silc_server_private_message function now checks, if we are router,
5132 that the destination ID really is valid ID, naturally.
5134 * In router when NEW_ID packet is received (for new client) the
5135 hash of the Client ID is saved in the ID Cache but the
5136 client->nickname is set to NULL, instead of putting the hash
5139 IDENTIFY command now also checks that client->nickname must be
5140 valid. If it is not if will request the data from the server who
5141 owns the client. Added new function
5142 silc_server_command_identify_check.
5144 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5145 to set the command to already allocated Command Payload.
5147 * Tested private message sending in router environment with two
5148 routers, two servers and two clients. Fixed minor bugs and now
5151 * Fixed segfault from client's NAMES command. Used to crash if
5154 * Forwarded packets must not be routed even if it is not destined
5155 to the receiver. Changed server code comply with this.
5157 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Added `require_reverse_mapping' boolean value to ServerParams
5160 structure. If TRUE (not default) the server will require that
5161 the connecting host has fully qualified domain name.
5163 If the reverse mapping is not required and hostname could not be
5164 found the IP address is used as hostname.
5166 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Implemented version string checking to both client and server.
5169 The check is incomplete currently due to the abnormal version
5170 strings used in development version of SILC.
5172 * Changed all command functions in server to use the new
5175 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Changed char *data to unsigned char *data in ID Cache system to
5178 support binary data as ID Cache data. Changed code to support
5179 binary data in lib/silccore/idcache.c.
5181 * Renamed silc_server_packet_relay_command_reply to
5182 silc_server_command_reply as it is normal packet receiving
5183 function. Rewrote the function to accept command replys for
5184 servers and not only for clients.
5186 * Mark remote router always as registered server if we are connecting
5187 to it. Otherwise, commands sent by the router to us are ignored.
5189 * All ID List find routines now returns the ID Cache Entry pointer
5190 as well if requested.
5192 * WHOIS command works now in router environment, tested with two
5193 routers, two servers and two clients.
5195 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5196 in router environment (as it is almost equivalent to WHOIS) but
5197 hasn't been tested thoroughly. Added new functions:
5199 silc_server_command_identify_parse
5200 silc_server_command_identify_send_reply
5201 silc_server_command_identify_from_client
5202 silc_server_command_identify_from_server
5204 * Disabled route cache adding because adding two different ID's with
5205 same IP replaces the old cache entry thus giving wrong route.
5206 The entry->router->connection is always the fastest route anyway
5207 so route cache may not be needed. Of course, new routes maybe
5208 established after receiving the ID when the entry->router->connection
5209 might not be anymore the most optimal.
5211 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Add route cache for received ID for fast routing.
5215 * Added silc_server_packet_route to route received packet on router
5216 that is not destined to us.
5218 * Renamed silc_server_get_route to silc_server_route_get.
5220 * Added id_string and id_string_len fields into SilcServer to
5221 include encoded ServerID for fast comparing without excess
5222 encoding of the ID's.
5224 * Cleaned up WHOIS command on server side. Added following static
5227 silc_server_command_whois_parse
5228 silc_server_command_whois_check
5229 silc_server_command_whois_send_reply
5230 silc_server_command_whois_from_client
5231 silc_server_command_whois_from_server
5233 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5234 arguments in command replies. All command functions should be
5235 updated to use this macro.
5237 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Minor typo fixes on command reply handling on server.
5241 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added silc_server_command_add_to_channel internal routine to add
5244 the client to the channel after router has created the channel and
5245 sent command reply to the server.
5247 * Added generic silc_server_send_command to send any command from
5250 * Use static buffer with ID rendering instead of duplicating data.
5252 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Fixed a channel user mode bug when joining to a channel server gave
5255 everybody channel founder rights, oops.
5257 * We mark ourselves as the router of the incoming server connection
5258 if we are router ourselves. This way we can check in some packet
5259 sending functions whether it is locally connected server. For
5260 incoming router connections we put NULL.
5262 * For router sending packets locally means now always sending the
5263 packet cell wide; to local clients and local servers. For normal
5264 server sending packet locally means sending it to only local
5267 * Fixed the JOIN command to really work in router environment. If the
5268 channel is created it is always created by the router. Router is
5269 also responsible of making the initial joining to the channel,
5270 sending JOIN notify to the sending server and distributing
5271 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5272 does not exist server doesn't do anything else but forward the
5273 command to the router which performs everything.
5275 * Added silc_server_send_channel_key function to send the Channel Key
5278 * Added silc_server_create_channel_key to create new channel key. The
5279 channel key is now re-generated everytime someone joins or leaves
5280 a channel, as protocol dictates. Note: channel->key_len is the
5283 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5286 packet_receive.[ch] to separate packet sending and receiving
5287 routines. The server.[ch] now includes everything else including
5288 actual packet processing (writing and reading data) and other
5291 Renamed silc_server_private_message_send_internal to
5292 silc_server_send_private_message. The routine is still though
5293 used only to relay private messages as server does not send
5294 private messages itself.
5296 Renamed silc_server_new_channel to silc_server_create_new_channel
5297 and added new function sicl_server_new_channel that handles the
5298 incoming New Channel packet. Added also new sending function
5299 silc_server_send_new_channel to send New Channel Payload.
5301 * Added new function silc_server_notify to process incoming notify
5302 packet to the server/router. Server may then relay the notify
5303 to clients if needed.
5305 * Added new function silc_server_new_channel_user to process incoming
5306 New Channel User packet. Router will redistribute the packet and
5307 send JOIN notify to its local clients and locally connected servers
5308 if needed. Normal server will send JOIN notify to its local client
5309 on same channel when received this packet. Added also corresponding
5310 sending function silc_server_send_new_channel_user to sent the
5313 * Added boolean route argument to send_notif_to_channel and
5314 packet_send_to_channel functions to attempt to route the packet
5315 if it is TRUE and send only locally if it is FALSE.
5317 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * silc_server_replace_id now broadcasts the received replace ID
5320 packet if it is not broadcast packet already. The router must
5321 broadcast to inform other routers about changed ID.
5323 * Added backpointer to server's router into SilcServer context in
5324 silcd/server_internal.h.
5326 * Fixed silc_server_packet_broadcast to send correct broadcast
5329 * The channel key is now distributed to the local client as soon
5330 as it is received from the router (in router environment) so that
5331 no other packet may be sent for the channel until client has
5334 * silc_server_remove_channel_user now broadcasts the received
5335 Remove Channel User packet if it is not broadcast packet already.
5336 The router must broadcast to inform other routers about removed
5339 * Added users field into SilcPacketContext that is a reference count
5340 of the context. One can increase the reference count by calling
5341 silc_packet_context_dup which is now changed to just increase the
5342 reference count instead of duplicating the data. The reference
5343 count is decresed by calling silc_packet_context_free that will
5344 free the data after the reference count hits zero.
5346 For now on the packet context and everything allocated into it
5347 (including the raw packet from network) must be freed by calling
5348 the new silc_packet_context_free function. Added also new function
5349 silc_packet_context_alloc that must be used now to allocate the
5350 context. This also means that if a routine is asynchronous from
5351 silc_[client/server]_packet_parse_type the packet context must
5352 be duplicated by calling silc_packet_context_dup. Otherwise it
5353 gets free'd after silc_[client/server]_packet_parse_type returns.
5354 Also, one must remember that if packet is duplicated then its
5355 reference count must be decresed by calling the free function as
5356 many times as it was duplicated.
5358 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5359 from both client and server.
5361 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Made joining to a channel working in router environment.
5365 * Cleaned up JOIN command on server side and create function
5366 silc_server_command_join_channel internal routine to make the
5369 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Changed silc_command_pending list to SilcDList. Also, added
5372 `ident' field to SilcServerCommandPending structure to identify
5373 the reply and to call correct callback.
5375 Added silc_server_command_pending_check function to replace the
5376 corresnponding macro. The silc_command_pending list is not
5379 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5380 to set identifier to previously allocated Command Payload. It
5381 is used to set identifier for command when resending Command
5384 * Added silc_command_payload_encode_payload to encode Command
5385 Payload buffer from SilcCommandPayload structure.
5387 * Added silc_argument_payload_encode_payload to encode Argument
5388 payload buffer from SilcArgumentPayload structure.
5390 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Changed WHOIS command to support router connection on server side.
5393 The whois request is always sent to router unless the server is
5394 standalone server. After server has received the reply from the
5395 router will it send the reply to the client.
5397 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5398 broadcast received broadcast packet. The function is used only
5399 by router. The broadcast packet is always sent to the router's
5402 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5403 render given ID to printable string, for log files for example.
5405 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Made basic router to router connections working. At least they
5408 can now connect to each other but nothing really works the way
5409 they are supposed - yet.
5411 * Added new initiator token to RouterConnection configuration
5412 file in silcd/serverconfig.[ch]. It is used to tell whether we
5413 are the initiator to the remote router or whether we'll expect
5414 the other end to connect.
5416 * Moved registering of listener task to silc_server_init, hence
5417 the server starts listenning as soon as it is run, even if it
5418 does not have connections to other routers. Let's see how well
5421 * Changed default connection retry timeouts for more suitable in
5424 * Removed cipher and such arguments from silc_idlist_add_client
5425 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5426 Added new function silc_idlist_add_data to add the keys and stuff
5429 * Added SilcIDListData structure and added it to SilcClientEntry
5430 and SilcServerEntry as their first field in the structure. This
5431 way we can explicitly cast the ID entries to the SilcIDListData
5432 structure and get common data for the entries. In past, we had
5433 to first check what type of connection it is and then cast it to
5434 correct ID entry type. Now, we can directly cast the opaque
5435 pointer to the SilcIDListData (no matter what ID entry it actually
5436 is) and get the data needed.
5438 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5441 in some circumstances even if threre were timeout tasks, though not
5442 IO tasks, but tasks anyway. Now fixed.
5444 * Defined SilcServerConnection structure to hold connection specific
5445 stuff about directly connected servers and routers. The definition
5446 is currently in silcd/server_internal.h. I thought about having
5447 a bit more important role fro this struct but for now it is used
5448 only when connecting to other server (or router actually).
5450 * Added connecting retry support in server when connecting to
5451 router(s). The retry feature implement exponential backoff
5452 algorithm. Also, added SilcServerParams structure to hold default
5453 parameters for server. For now, it include these retry settings
5454 and are hard coded. After server is moded to be as Silc Server
5455 Library this structure will be more important.
5457 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Changed client librarys channel->clients table to SilcList and
5460 changed code accordingly.
5462 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Changed client's channel table to SilcList and changed code
5465 accordingly. Also changed SilcChannelClientEntry to include back-
5466 pointer to the channel so that client entry can use that structure
5467 as list as well and we have fast cross-reference to the channel.
5468 This change dramatically decreased the complexity of channel
5469 handling with client entry and vice versa (removed one extra
5470 loop when searching for channel entry from many functions).
5472 * Changed server->sim from table to SilcDList and changed code
5475 * NAMES command can now be used from user interface. It will show
5476 the user list on the channel, neatly.
5478 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5479 Code now saves realname of the user if it becomes available.
5481 * Renamed configure.in to configure.in.pre and made ./prepare
5482 script to automatically add correct version string to
5483 configure.in which it creates from configure.in.pre.
5485 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * NAMES command reply now shows users mode with the nickname when
5490 * Moved silc_client_ch[u]mode[_char] functions from
5491 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5492 place sucks, they are utility functions and should be in some
5495 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5497 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5500 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added TRQ (efficient deque and list library) into lib/trq. This is
5505 a very good list library that is currently used in the SILC. Defined
5506 SilcList API over the library because I didn't like the API very
5507 much. See lib/trq/silclist.h for the API and examples of how to
5508 use the API. Fixed various places in the code to use the new
5509 SilcList API. The SilcList is meant for lists that has a structure
5510 already defined as a list. It is not suitable to add just some
5511 context to the list (in TRQ, the context is the list actually).
5513 So, I defined SilcDList that can be used for the purpose where
5514 predefined list structure does not exit. This can be used as
5515 such list. Now some context just can be added to the SilcDList.
5516 Currently this list is not used in the SILC just yet, though there
5517 are a lot places where this can replace dynamically allocated
5518 tables and I will fix these places, later, to use SilcDList.
5519 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5520 and use TRQ internally).
5522 Also fixed some annoying warning messages that the original TRQ
5523 code generated. Also minor changes to TRQ's Makefile.in.
5525 * Added support for querying by Client ID to both WHOIS and
5526 IDENTIFY commands into server, as required by the protocol.
5528 * Removed method function pointers from SilcBuffer structure. They
5529 weren't used to anything and just increased the context size for
5530 no good reason. This change also made silc_buffer_alloc and
5531 silc_buffer_free functions inline functions.
5533 * Disabled command flooding detection support until it's fixed so
5534 that it accepts commands in but does not execute them more than once
5537 * Added silc_net_localhost(), to return local hostname, into
5538 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5539 that must be initialized before calling silc_client_init.
5541 * Added new function: silc_server_send_notify_on_channels to send
5542 notify messages to all channels client has joined. It is assured
5543 that the message is sent only once per client.
5545 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5546 lib/silcutil/silcutil.[ch] as silc_format function. The new
5547 function is generic and is used by server as well, not only by
5548 the logging routines.
5550 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5551 the provided version string was not acceptable. Added new function:
5552 silc_ske_check_version into lib/silcske/silcske.h. The function
5553 must be implemented by the application (client or server) and it
5554 does not reside in the SKE library. The function checks the version
5555 string remote end sent.
5557 * Added back pointers (to opaque context and to SilcSocketConnection)
5558 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5560 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5561 duplicate packet context structure.
5563 * Changed `notify' client operation to send same arguments as client
5564 receives from server except for ID's. ID's are mapped to correct
5565 ID entry and that is returned. Also, if channel entry is not sent
5566 by server but the notify is for channel the channel entry is sent
5567 to application (otherwise application doesn't know that it is for
5568 channel (library gets it from packet's Destination ID)).
5570 * Added silc_client_remove_from_channels into client library to
5571 remove a client from all channels it has joined to. Used when
5572 received SIGNOFF notify from server. Added also new function
5573 silc_client_replace_from_channels to replace old ID entry with
5574 new ID entry on all channels. Used when received NICK_CHANGE
5577 * Fixed ID Cache list handling in silc_idlist_get_client in
5578 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5579 to get (or query) client by ID.
5581 * Updated TODO list.
5583 * Added connection authentication status message defined by the
5584 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5585 support for these into the code in client and server side.
5587 * Added generic function silc_client_send_command to send any command
5588 with variable argument list. Application should use this function
5589 to send commands if the command functions provided by the library
5590 does not suite for the application's user interface needs.
5592 * Added new `failure' client operation. Application is notified about
5593 received failure packet if client is executing a protocol. In this
5594 case the protocol's execution has failed.
5596 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5597 is required by the protocol.
5599 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5600 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5603 * Added status flag to SilcSKE object to indicate realtime status
5604 of the SKE protocol.
5606 * Application receives now exactly same command reply arguments as
5607 the library receives from server. However, if ID is received the
5608 corresponding ID entry is returned to the application (eg. Client
5609 ID is mapped to correct SilcClientEntry entry and that is returned).
5610 Changed command_reply client operation due to this change.
5612 * Changed all ID's in commands and in command replys as ID Payloads.
5613 Change affected both client and server side codes.
5615 All ID's sent in SILC network (with execption of ID's in SILC
5616 Packet header) are sent in ID Payload to support variable length
5619 * Server now notifies nick changes and notifies all clients on
5620 the channels about the new nickname (about the new Client ID,
5623 * Implemented CMODE command to change channel modes. Supports all
5624 channel modes defined by the protocol specs except ban and invite
5625 lists. (Also, private channel key mode is supported but support for
5626 setting private channel key in client is missing, thus, this mode
5627 has no effect on client side (except that server requires that the
5628 client uses private channel key and normal channel traffic does not
5631 Also, invite mode works per se, but INVITE command does not work
5632 yet correctly, so you can set channel as invite only channel but
5633 inviting clients to the channel does not work (it is yet to be
5634 thought what's the best way to do it).
5636 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5637 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5638 Implemented CUMODE command to change user's mode on the channel.
5639 Supports all modes defined by the protocol specs.
5641 * Added NAMES command reply to return users modes on the channel.
5643 * Removed unnecessary and slow ciphers from lib/silccrypt.
5645 * Set SO_KEEPALIVE option to connection sockets by default.
5647 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5649 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5650 redefined the Notify Payload into protocol specs.
5652 * Added silc_id_payload_parse_id to get ID directly from raw
5655 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5658 accept searching by Client ID as well.
5660 * Added support for LEAVE and SIGNOFF notify types in client library.
5662 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5663 to parse ID Payload from raw data.
5665 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added flags parameter into silc_ske_assemble_security_properties
5668 function in lib/silcske/silcske.[ch].
5670 * Changed notify client operation to fit better for notify messages
5671 sent by server. The notify payload received from server is now
5672 passed to the application (after parsing it to SilcNotifyPayload).
5673 It is application's responsibility to retrieve the arguments
5674 from the payload and show the message the way it wants. The message
5675 sent by server is implementation specific.
5677 * Changed public keys to comply with the protocol specification.
5678 Old public keys are not supported anymore and are not compatible.
5680 * Removed nickname from Channel Payload as the latest draft removed
5681 it. The client must resolve the nickname from the NAMES command
5682 reply received when it joined the channel.
5684 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5686 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Fixed some errors in protocol specification drafts.
5690 * Created lib/silccore/silcnotify.c to implement Notify Payload
5691 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5692 generic payloads described by protocol specifications. The file
5693 includes implementations for ID Payload and Argument Payload.
5695 * Changed Command Payload implementation to use the new Argument
5696 Payload. Changed command_xxxx_payload to command_payload_xxxx
5697 to comply with SILC coding conventions.
5699 * Added suppport for Argument Payload handling in Notify Payload
5700 implementation as protocol requires it. Added the new support
5701 into server and client lib as well.
5703 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added support for multiple nicknames on same channel. [n] is
5706 added locally to the nickname if there are more than one same
5707 nicknames on the channel.
5709 * Server now sends all nicknames that matched WHOIS request.
5710 Client also shows the list received from server.
5712 * Added TOPIC command to client side. User can now set and show
5713 current topic on channel.
5715 * Added MOTD command to client and server. Also, server sends the
5716 motd when client connects to the server.
5718 * Changed version strings to comply ISO 8601.
5720 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Fixed protocol error handling in client library. It should now
5723 cope even if the SKE fails for some reason.
5725 * Made new protocol specification drafts for submitting to IETF.
5727 * Implemented TOPIC command to server in silcd/command.c.
5729 * Added two new notify types into lib/silccore/silcnotify.h:
5730 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5731 notify nickname change and topic setting/change on a channel.
5733 * API change of command_reply operation in client library. The
5734 application gets now the status type received from server as well.
5736 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5740 * Cras fixed and optimized the packet handling even further and
5741 it should work now. Minor change to the prototype of function
5742 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5744 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Added new function into lib/silcutil/silcschedule.[ch]:
5747 silc_schedule_with_fd to select() a specified fd. The function
5748 returns after timeout expires or data arrives or goes. The
5749 function is used by packet routines to wait that all data is
5750 received from network.
5752 * Fixed data reading from network in lib/silccore/silcpacket.c.
5753 The code now assures that all data is read from the fd and then
5754 continues packet processing. This was a bug fix since the code
5755 used to drop some data in some circumstances.
5757 * Added new function into lib/silcclient/client.[ch]:
5758 silc_client_start_key_exchange to start key exchange after
5759 connection has been established to server. The code internally
5760 now uses this funtion but its main purpose was to provide it
5761 for applications that perform their own connecting. After
5762 application has created a connection it merely calls this
5763 function to start the key exchange between client and server.
5764 The library takes care of everything else after that.
5766 Updated also lib/silcclient/README to explain the usage of
5769 * Do not send to application information that connection has
5770 been established. Application gets notified it by connect
5773 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Applied cras's patch to add silc_schedule_one function. The
5776 function runs scheduler once and returns.
5778 * Fixed the scheduler after cras messed it up. The timeout
5779 handling works now as it's supposed to work.
5781 * Added into lib/silccore/ silcnotify.h to include notify
5782 message types support. Changed silc_server_send_notify*
5783 functions, in server.[ch], to support those new notify types.
5784 Added the support for the notify types into client library,
5785 as well. Added new notify client operation into ops.h in
5788 * Changed silc_server_packet_send_to_channel to send normal
5789 packets instead of just channel message packets. The function
5790 is now used to send the notify packets to channels. It is not
5791 used to send channel message packets anymore, as server never
5794 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5795 va_arg()s as it seems to require it nowadays. I guess, if SILC
5796 is compiled with older va_arg() the new code should work anyway.
5798 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Splitted core library. Core library (lib/silccore) includes
5801 now only SILC protocol specific core (and common) components.
5802 Created new utility library (lib/silcutil) that includes more
5803 generic purpose stuff. The stuff for util library was taken
5804 from the old core library. This was minor and easy split.
5806 * Created SILC Client Library (lib/silcclient) that includes
5807 implementation of the SILC client without user interface. This
5808 was major move from silc/ directory. The code has been changed
5809 so that it is transparent towards the user interface. The
5810 silc/ directory includes now the same user interface as before
5811 and it uses the new client library. Read lib/silcclient/README.
5812 Basicly, the client library performs everything else related
5813 to SILC except user interface handling. Also, configuration
5814 files are considered to be part of user interface and library
5815 does not handle them.
5817 This change also changed a lot of structures, function naming etc.
5818 Most important change was that SilcClientWindow object was
5819 renamed to SilcClientConnection in the client library. Created
5820 also new file lib/silcclient/ops.h. Also added new files
5821 silc/local_command.[ch] and silc/client_ops.[ch].
5823 All these changes were made to make it easier for user interface
5824 designers to create what ever user interface for the SILC client
5827 It is also expected that the server will be moved to lib
5828 directory as well and SILC Server Library will be created;
5829 sometimes in the future.
5831 * Removed Local commands from lib/silccore/silccommand.h as
5832 they are application specific and new client library does not
5833 handle any of those anymore.
5835 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5836 old client implementation in silc/.
5838 * Added support for callback functions in SILC_LOG_* macros.
5839 Application can now set its own callbacks that will be called
5840 instead of using the default functions that will always print
5841 the debug messages to stderr (or stdout). Also, debugging can
5842 now be disabled by setting silc_debug to FALSE and re-enabled by
5843 setting it to TRUE. Note, that logging will still work even
5844 if debugging is disabled.
5846 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5847 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5848 silc_log_reset_debug_callbacks.
5850 * To enable debugging in silc client one must give now -d
5851 option on command line.
5853 * Changed silc_schedule_init to automatically allocate task queues
5854 if they are not allocated before calling it.
5856 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added GMP 3.1 into math library.
5860 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5863 a channel in SILC network. The packet is used by servers and
5864 routers to notify other routers that user has left a channel.
5865 This little feature was missing until now. Added the feature
5866 to protocol specification as well.
5868 Added functions: silc_server_send_remove_channel_user and
5869 silc_server_remove_channel_user into server.[ch].
5871 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5872 lib/silccore/silcpacket.h. However, they are not implemented
5875 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Fixed joining to a channel and sending channel messages
5878 between server and router. The channel message sending should
5879 now work inside a cell.
5881 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Fixed the private message sending between server and router.
5884 The private message sending should now work inside a cell.
5886 * Added silc_server_replace_id into server.[ch] to replace
5887 existing ID in the SILC network.
5889 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5890 and silc_idlist_replace_server_id into idlist.[ch] in server.
5892 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Fixed the server to server connections. Server can again now
5895 connect to router. Router to router connections probably does
5898 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Added dynamic protocol registering support. Now protocols can
5901 registered and unregistered on the fly. Patch by cras.
5903 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Added lib/contrib directory to hold routines that some platforms
5906 don't have but are needed by SILC.
5908 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5909 into lin/contrib to provide getopt() and getopt_long() for
5910 those who don't have it.
5912 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Added AWAY command to client. When away message is set and
5915 client receives a private message packet the client automatically
5916 replies to the sender with the away message.
5918 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5919 bug seemed to be the cause of recent problems when compiling
5922 * Added version detection support to SKE protocol specification
5923 and added the new changes to the SKE implementation as well.
5924 There were other minor changes in the SKE protocol as well.
5926 Many changes in lib/silcske/silcske.[ch] and in
5927 lib/silcske/payload.[ch].
5929 * Added ^U functionality, clear input line. Patch from cras.
5931 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Mainly small bugfixes on core library. Fixed some debugging
5934 logging and buffer overflow in silclog.c.
5936 * Updated config.sub and config.guess on the distribution tree.
5938 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added command lagging support in server. Client may execute
5941 commands now only once in two seconds.
5943 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Optimized packet reception. MAC computation and checking is now
5946 also more optimized. A lot previously duplicated code is now
5947 used as generic by both client and server.
5949 * Fixed key pair generation in clientutil.c
5951 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Added into lib/silccore/silcbufutil.[ch] new function;
5954 silc_buffer_realloc.
5956 * Moved generic packet sending/encryption functions to
5957 lib/silccore/silcpacket.[ch] from client and server. Some
5958 rewriting of the functions.
5960 * Moved all generic packet reception/decryption functions to
5961 lib/silccore/silcpacket.[ch] from client and server. The
5962 packet processing is now much cleaner in both client and server.
5963 These were major changes in both client and server.
5965 * Created many common functions in server to do packet sending.
5966 Previously code were duplicated a lot, this has been removed
5969 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Rewrote major parts of the ID cache system. Don't know
5972 whether it is better now or not but at least the API is more
5975 * Major rewrite on ID cache stuff on client because of the ID
5976 cache API changes. Added idlist.c to client.
5978 * Also major rewrite on ID cache stuff on server as well.
5979 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5980 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5981 in hand, instead they are all put into the ID cache system now.
5982 All server_idlist_* routines uses ID cache now instead of
5983 traversing its own lists (those lists does not exist anymore).
5984 SilcIDList though still exists. Also, SilcXXXEntry's are
5987 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Finally made the SKE implementation compliant to the protocol
5990 specification. All mp integers are now binary encoded as
5991 opposed being HEX encoded.
5993 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5996 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5997 functions: silc_[encode/decode]_pem. Also added function
5998 silc_encode_pem_file to PEM encode with newlines ('\n') for
6001 * SILC public keys are now encoded either PEM or binary. Same
6002 option is for private keys as well. By default private keys
6003 are binary encoded and public keys PEM encoded. Silly HEX
6004 encoding were removed.
6006 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6007 function to create fingerprints.
6009 * Fixed a bug in SHA1; does not change the original data anymore.
6011 * Partly implemented INFO command on client and server side.
6012 Fixed CLEAR command. Changes to SERVER command; show current
6013 server(s) when giving command without arguments. Added
6014 VERSION command to client.
6016 * Added check to server that unregistered connections cannot
6017 execute commands (unless it is specificly allowed).
6019 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Fixed screen refresh.
6023 * Fixed channel joining bug from client. On some circumstances
6024 client tried to join to a channel it had already joined.
6026 * Added public key verification process into client's protocol.c.
6027 The client now verifies the public key from user and saves
6028 it into ~./silc/serverkeys/ directory.
6030 Added into: clientutil.[ch]: silc_client_verify_server_key.
6032 * Changed SKE protocol's silc_ske_initiator_finish function
6033 to accept callback function that verifies the received public
6034 key. Removed old silc_ske_verify_public_key function.
6036 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6039 silc_pkcs_private_key[_data]_set.
6041 * Made the password and public authentication more cleaner in
6042 server's protocol.c.
6044 * Removed historic and obsolete protocol `channel_auth' from
6045 both client and server.
6047 * Removed wrong way of sending command status messages from
6048 server to client in server's command.c. The old way violated
6049 protocol specification.
6051 Changes to silccore/silccommand.[ch]: removed
6052 silc_command_encode_status_payload -> not needed anymore,
6053 changed silc_command_encode_payload_va to accept extra
6054 argument on variable argument list. The argument type must
6055 now be provided to the function. Also, added new function:
6056 silc_command_encode_reply_payload_va which is same as
6057 normal command_encode_payload_va except command status type
6058 is provided as extra argument.
6060 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Added ~./silc directory handling. The directory includes the
6063 public and private keys for the client.
6065 Added silc_client_check_silc_dir, silc_client_create_identifier
6066 and silc_client_load_keys.
6068 * Implemented SILC protocol compliant public key. Added public
6069 and private key saving to and loading from files.
6071 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6072 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6073 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6074 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6075 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6077 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6078 silc_pkcs_load_[public/private]_key.
6080 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Added silc_server_get_route (route.[ch]) to get connection
6083 data for the fastest route for given ID.
6085 * Implemented INVITE command on client and server. The command
6086 were re-defined in the SILC Protocol Specification and the
6087 implementation now complies with the specification.
6089 * Implemented PING command on client and server.
6091 * Implemented NAMES command on client and server. The server side
6092 supports currently only normal server not router server yet.
6093 Some changes to NAMES definition in SILC protocol specification.
6095 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Implemented LEAVE command on client and server.
6099 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6100 again. This change was made to the protocol as well. Server
6101 should not violate the protocol specification anymore.
6103 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6106 was tested. SOCKS4 was not but should work anyway.
