1 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * If the incoming packet type is REKEY or REKEY_DONE process
4 that packet always synchronously. Fixes yet another MAC
5 failed error on slow (dialup) connections. Affected file
6 lib/silcclient/client.c and silcd/server.c.
8 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Call check_version SKE callback for initiator too. Affected
11 file lib/silcske/silcske.c.
13 * Implemented fix for security hole found in the SKE that was
14 fixed in the specification few days back; the initiator's
15 public key is now added to the HASH value computation.
16 Added backwards support for the old way of doing it too, for
17 old clients and old servers. Affected file is
18 lib/silcske/silcske.c.
20 * Enabled mutual authentication by default in SKE. If initiator
21 is not providing mutual authentication the responder will
22 force it. This will provide the proof of posession of the
23 private key for responder. The affected files are
24 lib/silcclient/protocol.c and silcd/protocol.c.
26 * Do not cache anymore the server's public key during SKE.
27 We do mutual authentication so the proof of posession of
28 private key is done, and if the server is authenticated in
29 conn auth protocol with public key we must have the public
30 key already. Affected file silcd/protocol.c.
32 * Added new global debug variable: silc_debug_hexdump. If
33 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
34 file lib/silcutil/silclog.[ch].
36 * Fixed compilation warning due to char * -> const char *.
37 Affected files lib/silcutil/silcnet.h, and
38 lib/silccore/silcauth.[ch].
40 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
42 * Fixed CMODE command when new channel key was created. If
43 the creation failed the old key was removed. Next time giving
44 same command would crash the server since the old key was
45 freed already. Affected file silcd/command.c.
47 * Fixed the silc_server_announce_get_channels to not crash
48 on reconnect. Affected file silcd/server.c.
50 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
52 * Added silc_log_set_debug_string function to set a regex
53 string to match for debug output. Only the function names,
54 or filenames matching the given debug string is actually
55 printed. This way it is possible to filter out those debug
56 strings that user is not interested in.
58 Fixed a bug in silc_string_regexify.
60 Affected files lib/silcutil/silclog.[ch], and
61 lib/silcutil/unix/silcunixutil.c.
63 * Changed the -d options in both server and Irssi SILC client
64 to take the debug string as argument. Affected files
65 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
67 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
69 * Added silc_hash_babbleprint to create a Bubble Babble
70 Encoded fingerprint. The encoding is developed by Antti
71 Huima (draft-huima-babble-01.txt), and it creates human
72 readable strings out of binary data. Affected file
73 lib/silccrypt/silchash.[ch].
75 * Print the babble print now in addition of fingerprint as well
76 in Irssi SILC client. Affected files are
77 irssi/src/fe-common/silc/module-formats.[ch],
78 irssi/src/fe-common/silc/core/client_ops.c.
80 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
82 * Fixed a security problem found in SKE. The initiator's
83 public key too is now added to the HASH hash value creation
84 which is signed by the responder to create the SIGN value.
85 This will prevent anyone in the middle to lie to the responder
86 about the initiator's public key. If this is done now, the
87 man in the middle will get caught. Updated the protocol
90 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
92 * Better installation directory handling. Configure module
93 paths and other paths automatically to example_silc* files
94 in doc/. A patch by toma.
96 * Fixed compiler warning from MPI library, and from SILC RNG.
99 * Added SILC_SERVER_PID_FILE to define the pid file for server.
100 It can be configured with ./configure. A patch by toma.
102 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
104 * Find correct make to use in prepare-clean. A patch by
105 toma. Affected file prepare-clean.
107 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
109 * Added irssi variables use_auto_addr, auto_bind_ip,
110 auto_bind_port and auto_public_ip.
112 * Changed the interface for silc_client_send_key_agreement
113 in lib/silcclient/silcapi.h
117 irssi/src/silc/core/silc-core.c
119 lib/silcclient/silcapi.h
120 irssi/src/silc/core/silc-channels.c
121 lib/silcclient/client_keyagr.c
124 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Added silc_pkcs_public_key_compare to compare two
127 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
129 * Check that the client who set the founder mode on the
130 channel is the same client that is giving the founder
131 mode to itself. It is done by comparing the saved public
132 key (it is saved even in the authentication is passphrase).
133 Affected file silcd/command.c.
135 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Do not process packet for disconnected socket connection.
138 Affected file lib/silccore/silcpacket.c.
140 * Process the DISCONNECT packet through scheduler in the
141 client library. Affected file lib/silcclient/client.c.
143 * Fixed the silc_client_packet_parse to not to increase
144 the packet sequence number if the conn->sock and the
145 current socket connection is not same. This can happen
146 for example during key agreement when the conn includes
147 multiple socket connections (listeners). Affected file
148 lib/silcclient/client.c.
150 * The sender of the file transfer request now provides also
151 the pointer (listener) for the key exchange protocol. If
152 the listener cannot be created then it sends empty key
153 agreement and lets the receiver provide the listener.
155 Added `local_ip' and `local_port' arguments to the
156 silc_client_file_send. If they are provided they are used,
157 if not then it will attempt to find local IP address, if
158 not found or bind fails then the remote client will provide
161 Affected files are lib/silcclient/client_ftp.c and
162 lib/silcclient/silcapi.h.
164 * Extended the FILE SEND command to support defining the
165 local IP and port for key exchange listener. They are
166 optional. Affected file irssi/src/silc/core/silc-servers.c.
168 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
170 * Defined to WHOIS command reply the sending of fingerprint
171 of the client's public key (if the proof of posession of the
172 corresponding private key is verified by the server).
173 Updated to the protocol specification.
175 * Added support of receiving the client's public key's
176 fingerprint in command reply in client library. Affected
177 file is lib/silcclient/command_reply.c, and
178 lib/silcclient/idlist.[ch].
180 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
182 * Do not send over 128 chars long nickname to the server
183 in NICK command. Affected file lib/silcclient/command.c.
185 * Do not send over 256 chars long channel names to the server
186 in JOIN command. Affected file lib/silcclient/command.c.
188 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Assure that silc_server_close_connection cannot be called
191 twice for same socket context. Affected file is
194 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
196 * Send error message to application if opening file for
197 writing during file transfer fails. Affected file is
198 lib/silcclient/client_ftp.c.
200 Remove all file transfer sessions for a client that we're
201 removing from ID cache.
203 Affected file is lib/silcclient/client_ftp.c.
205 * Fixed silc_net_addr2bin to return correct address. Affected
206 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
208 * Fixed file transfer session removing on signoff notify.
209 Affected file irssi/src/silc/core/silc-servers.c.
211 * Added the SilcClientFileError to be returned in the monitor
212 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
213 Affected file lib/silcclient/silcapi.h.
215 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
217 * Fixed a crash in silc_client_ftp_free_sessions and
218 silc_client_ftp_session_free_client. Affected file
219 lib/silcclient/client_ftp.c.

222 to indicate if the server entry is disabled. Affected file
223 silcd/idlist.h, silcd/command[_reply].c.
225 * SILC server adds now /var/run/silcd.pid everytime it is
226 started. Affected file silcd/silcd.c.
228 * Added silc_server_packet_send_clients to send a packet to
229 the provided table of client entries. Affected file
230 silcd/packet_send.[ch].
232 * Fixed a crash in client resolving in client_prvmsg.c in
233 client library. Affected file lib/silcclient/client_prvmsg.c.
235 * Do not actually remove the client directly from ID cache
236 during SERVER_SIGNOFF, but invalidate it. This way we
237 preserve the WHOWAS info for the client. Affected file
240 * Fixed SERVER_SIGNOFF notify handling in the server. The
241 server is now able to process incoming SERVER_SIGNOFF notify
242 for a server that it doesn't even know about. It will remove
243 the clients provided in the notify. Affected file
244 silcd/packet_receive.c.
246 * Check for partial packet in data queue after every packet that
247 was found from the queue. Return and wait for more data if
248 there is partial data in queue. Affected file is
249 lib/silccore/silcpacket.c.
251 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
253 * Added SilcClietFileError enum to indicate error in
254 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
255 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
256 Affected files lib/silcclient/silcapi.h and
257 lib/silcclient/client_ftp.c.
259 * Check that newsize in silc_buffer_realloc is larger than
260 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
262 * Added better monitor of file transfers. It now monitors
263 key agreement protocol during the file transfer too. Added
264 error reporting too. Affected files
265 irssi/src/silc/core/silc-servers.c,
266 irssi/src/fe-common/silc/module-formats.[ch].
268 * Wrote a help file for FILE command.
270 * Added silc_rng_global_get_byte_fast to get not-so-secure
271 random data as fast as possible. Random data is read from
272 /dev/urandom if available and from the SILC RNG if not
273 available. It is used in padding generation. Affected file
274 lib/silccrypt/silcrng.[ch].
276 * All packets in client library are now processed synchronously.
277 Optimized packet processing a lot. Affected file
278 lib/silcclient/client.c.
280 * All server connection packets are processing synchronously
281 now in server, to optimize packet processing. Affected file
284 * Include files are installed now only in Toolkit distribution
285 if make install is given. Affected files: all Makefile.am's.
287 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
289 * Assure that silc_client_notify_by_server_resolve does not
290 resolve the client information multiple times. If it cannot
291 be found by the first it cannot be found at all. Affected
292 file lib/silcclient/client_notify.c.
294 * Fixed WHOWAS command reply calling. Affected file
295 lib/silcclient/command_reply.c.
297 * Removed all references to silc_idlist_get_client from the
298 Irssi SILC client since that call is internal call used by
299 the library. The Irssi SILC client will use now client
300 retrieval functions found in silcapi.h.
302 * Fixed a bug in resolving nickname info before sending
303 private message. It used freed memory. Affected file
304 irssi/src/silc/core/silc-servers.c.
306 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
308 * Assure my_channels statistics cannot go negative in server.
309 Affected files silcd/server.c, silcd/server_util.c.

321 lib/sftp/sftp_fs_memory.c.
323 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
325 * Added silc_net_localip to return local host's IP address.
326 Affected file lib/silcutil/silcnet.[ch].
328 * If key exchange or rekey protocol is active for a connection
329 parse all packets syncronously since there might be packets
330 in packet queue that we are not able to process without first
331 processing packets before them. Affected file silcd/server,
332 lib/silcclient/client.c.
334 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
335 whether library should continue processing the packet.
336 Affected file lib/silccore/silcpacket.h.
338 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
339 SilcSFTPMonitorData to SFTP server to monitor various
340 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
341 lib/silcsftp/sftp_server.c.

348 transmission. Affected file lib/silcclient/client_ftp.c,
349 lib/silccilent/client.[ch].
351 * Added new local command FILE to the Irssi SILC Client.
352 It is used to perform the file transfer. It has subcommands
353 SEND, RECEIVE, SHOW and CLOSE. Affected files
354 irssi/src/silc/core/client_ops.c,
355 irssi/src/silc/core/silc-server.[ch].

367 lib/silcutil/silcutil.[ch].
369 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Resolve the client info when received private message or
372 channel message for a client which nickname we don't know.
373 Affected files lib/silcclient/client_prvmsg.c and
374 lib/silcclient/client_channel.c.
376 * Do not crash in /KEY if client is not connected. Affected
377 file irssi/src/silc/core/silc-channels.c.
379 * Added SilcClientStatus field to the SilcClientEntry in the
380 lib/silcclient/idlist.h.
382 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
383 is incomplete and is being resolved, it won't be resolved
386 Make sure also that USERS command reply does not resolve
387 twice information. Affected file is
388 lib/silcclient/command_reply.c.
390 Make sure that silc_client_get_clients_by_list does not
391 resolve twice same information.
393 * Check for valid client->id in the silc_server_free_client_data.
394 Affected file silcd/server.c.
396 * Fixed /GETKEY nick@server not to crash if the server entry
397 is not found. Affected file lib/silcclient/command.c.
399 * Fixed the silc_server_check_cmode_rights to check the
400 requested modes correctly. Affected file silcd/command.c.
402 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
404 * Better checks for non-printable chars in nick added.
405 Affected file silcd/command.c.
407 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
409 * Call the silc_server_udpate_servers_by_server in the
410 primary router that comes back online in the backup resuming
411 protocol. Otherwise it routes packets wrong. Affected file
412 silcd/server_util.[ch], silcd/server_backup.c.
414 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
416 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
417 lib/silcutil/silcbuffmt.[ch].
419 * Redefined the SILC packet header to include the padding
420 length. Affected file lib/silccore/silcpacket.[ch].
422 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
423 length for maximum padding up to 128 bytes). Affected
424 file lib/silccore/silcpacket.h.
426 * Removed all backwards support for old 0.5.x MAC thingies.
427 The SILC packet header change makes it impossible to be
428 backwards compatible.
430 * Send the ENDING packet with timeout in the backup resuming
431 protocol. This is to assure that all routers has connected
432 to the primary router. Affected file silcd/server_backup.c.
434 * Changed the RNG to take the first IV from random data. It
435 used to take it from zero actually. Changed the RNG also
436 to use /dev/urandom during session. /dev/random is used
437 in initialization. Affected file lib/silccrypt/silcrng.[ch].
439 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
441 * Changed the SILC packet header to have the first two bytes
442 (the packet length) encrypted. Affected files aroung the
443 code tree, lib/silccore/silcpacket.[ch]. Removed the
444 SilcPacketCheckDecrypt callback. It is not needed anymore
445 since the silc_packet_receive_process will determine now
446 whether the packet is normal or special.
448 * Implemented the unidirectional MAC keys. Affected files
449 lib/silcske/silcske.c, silcd/protocol.c and
450 lib/silcclient/protocol.c.
452 * Implemented the packet sequence number to the MAC computation.
453 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
454 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
455 lib/silcclient/protocol.c.
457 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
459 * Allow backup router to announce servers. All servers
460 announced by backup router are added to the global list
461 automatically. Update hte server's socket to our primary
462 router also when backup router announces a server.
463 Affected file silcd/packet_receive.c.
465 * Do not update the client->router in the function
466 silc_server_udpate_clients_by_server if the client is on
467 global list. We might fail to find any specific server
468 for locally connected clients and local cell clients. They
469 should still use the `from' and not `to' as client->router.
470 This fixes backup router resuming protocol. Affected file
473 * Decrease channel statistics count only if the channel
474 deletion worked. Affected files are silcd/server.c and
477 * Added silc_server_update_servers_by_server to update origin
478 of all server entries. Used during backup router protocol.
479 Affected files silcd/server_util.[ch], silcd/server.c. and
480 silcd/backup_router.c.
482 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
483 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
484 silc_hmac_get_hash and silc_hmac_get_name. Affected file
485 lib/silccrypt/silchmac.c.
487 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Assure that router cannot reroute the same channel message
490 to the sender. Affected file silcd/packet_receive.c.
492 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
494 * Made better checks that the channel message is not sent
495 to the router it came from. Affected file is
496 silcd/packet_send.c. Fixed memory leak too.
498 * Announce informations for incoming router connection, but
499 only after checking if it is replaced by backup router.
500 Affected file silcd/packet_receive.c.
502 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
504 * Fixed the backup resuming protocol to work in multiple
505 router environment. Affected file silcd/server_backup.c.
507 * Route packet only to one router in the function
508 silc_server_packet_send_to_channel. Affected file is
511 * Fixed silc_server_send_notify_dest to set the broadcast
512 flag. Fixed the silc_server_send_notify_topic to actually
513 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
514 Affected file silcd/packet_send.c.
516 * Changed the SFTP Filesystem interface. Changed the
517 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
518 the filesystem operation function. The SilcSFTPFilesystem
519 is now a context that is allocated by all filesystem allocation
520 functions and it already includes the operations structure
521 and filesystem specific context. It is given as argument
522 now to the silc_sftp_server_start. This made the interface
523 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
524 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
526 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
528 * Changed the backup router adding and getting interfaces
529 in the server. The router that will be replaced by the
530 specified backup router is now sent as argument. Affected
531 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
534 * Added silc_net_addr2bin_ne to return the binary form of
535 the IP address in network byte order. Affected files
536 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
538 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
540 * Check for existing server ID in silc_server_new_server
541 and in silc_server_connect_to_router_final and remove the
542 old entry if it exists. Affected file silcd/packet_receive.c,
545 * Send the channel message always to only one router, either
546 in upstream or downstream. Affected file is
549 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
551 * Wrote the definition of the backup resuming protocol to the
552 protocol specification.
554 * Removed one redundant channel key generation from normal
555 server during joining procedure. Removed one redundant
556 channel key sending from server to router during joining
557 procedure. Affected file silcd/command.c.
559 * Made minor bugfixes to the backup router resuming protocol.
560 Affected file silcd/server_backup.c, server.c.
562 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
564 * Added --disable-asm configuration option. Affected files
565 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
568 * Implemented the backup resuming protocol that is used to
569 resume the primary router position in the cell after the
570 primary router comes back online. Affected files
571 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
572 and silcd/server_util.[ch].
574 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
576 * Sleep two (2) seconds after sending QUIT command to server.
577 Affected file lib/silcclient/command.c.
579 * Assure that if outgoing data buffer is pending do not force
580 send any data. Affected file silcd/packet_send.c.
582 * Assure that if outgoing data buffer is pending do not force
583 send any data. Affected file lib/silcclient/client.c.
585 * Implemented the backup router support when the primary router
586 goes down. The servers and routers can now use the backup
587 router as new primary router without loosing connectivity.
589 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
591 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
592 in the server to indicate disabled entry. All data read
593 from the connection will be ignored and no data is sent
594 for entry that is disabled. Affected files are
595 silcd/idlist.h, silcd/server.c.
597 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
599 * Created SFTP client and server test programs in the
600 lib/silcsftp/tests directory.
602 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Implemented memory filesystem (virtual filesystem) for
605 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
608 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Implemented the SFTP (SSH File Transfer Protocol) to the
611 lib/silcsftp. It includes SFTP client and SFTP server
614 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Moved lib/silccore/silcprotocol.[ch] to the
617 lib/silcutil library.
619 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
620 take variable argument list pointer as argument. Affected
621 file lib/silcutil/silcbuffmt.[ch].
623 * Added silc_buffer_set function that is used to set data
624 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
625 Affected file lib/silcutil/silcbuffer.h.
627 * Changed various routines in the core library to use the new
628 silc_buffer_set instead of allocating new buffer only for
631 * Added 64-bit value formatting and unformatting support to the
632 silc_buffer_[un]format routines. Affected file is
633 lib/silcutil/silcbuffmt.[ch].
635 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
636 to includes/bitmove.h.
638 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Fixed channel user mode saving in client library. Affected
641 file lib/silcclient/command[_reply].c.
643 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
645 * Defined the file transfer to the SILC Protocol. Added
646 new packet type SILC_PACKET_FTP and defined File Transfer
647 Payload. The mandatory file transfer protocol is SFTP
648 (SSH File Transfer Protocol). Affected file in addition
649 of the internet draft is lib/silccore/silcpacket.h.
651 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
652 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
653 is used as part of backup router protocol when the primary
654 router of the cell is back online and wishes to resume
655 the position as primary router.
657 * Redefined the MAC generation keys in the protocol. The
658 same key is not used anymore in both direction. Both
659 direction will now use different keys for sending and
660 receiving. This fixes a potential security flaw. This
661 change causes incompatibilities in the protocol.
663 * Redefined also the MAC computation from the packet.
664 An packet sequence number is now added to the MAC
665 computation. This prevents possible replay attacks against
666 the protocol. This change too causes incompatibilities
669 Added `sequence' field to the SilcPacketContext to hold
670 the current sequence number for the packet.
672 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Added `created' field to the SilcIDListData in the file
675 silcd/idlist.h to indicate the time when the entry was
678 * Added `created' field to the SilcChannelEntry too. Affected
681 * Added `creation_time' aguments to all the announcement functions
682 in the server. If it is provided then only the entries that
683 was created after the provided time frame are actually
684 announced. Affected file silcd/server.[ch].
686 * The protocol says that the Channel ID's IP address must be
687 based on the router's IP address. Added check for this in
688 the silc_server_new_channel when processing incoming New Channel
689 Payload. Affected file silcd/packet_receive.c.
691 * Print out the correct version with --version in SILC client.
692 Affected file irssi/src/silc/core/silc-core.c.
694 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
696 * Fixed WHOWAS command to check for completnes of the client
697 entry always, not just when the command is coming from client.
698 Affected file silcd/command.c.
700 * Added new function silc_server_packet_queue_purge to purge the
701 outgoing data queue to the network. After the function returns
702 it is guaranteed that the outgoing packet queue is empty.
703 Affected file silcd/packet_send.[ch].
705 * Purge the outgoing packet queue in the rekey protocol's final
706 callback to assure that all rekey packets go to the network
707 before quitting the protocol. Affected file silcd/server.c.
709 * Added silc_client_packet_queue_parse as similar function as
710 in server to the client library. The affected file is
711 lib/silcclient/client.c.
713 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Splitted silcd/server.c and created silcd/server_util.[ch]
716 for utility functions.
718 * Added new socket flag SILC_SF_DISABLED to indicate that the
719 connection is open but nothing can be sent to or received from
720 the connection. Affected file lib/silcutil/silsockconn.[ch].
721 The checking for disabled socket is checked in the low level
722 silc_socket_write and silc_socket_read functions.
724 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Allow only nicknames and channel names that fits into the
727 7-bit unsigned char ASCII set. Affected file silcd/command.c.
729 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
731 * When processing JOIN command reply in server check that if
732 the channel exists in our global list we'll move it the local
733 list. Affected file silcd/command_reply.c.
735 * Fixed the check whether client is joined on the channel already
736 in JOIN command. Affected file lib/silcclient/command.c.
738 * Fixed the JOIN command reply to check whether the channel
739 already exists. Affected file lib/silcclient/command_reply.c.
741 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Added silc_ske_status_string to map the SKE error numbers
744 to readable strings. The affected files are
745 lib/silcske/silcske[_status].[ch].
747 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
749 * Do not show the private channels on the WHOIS channel list
750 as it is not allowed by the protocol. The affected file is
753 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Assure that the packet length digged from the actual packet
756 is something sensible in the silc_packet_decrypt_rest_special
757 in lib/silccrypt/silcpacket.c.
759 * Free and NULL the allocated pointer in silc_hmac_alloc if
760 the HMAC allocation fails. The affected file is
761 lib/silccrypt/silchmac.c.
763 * Print the selected security properties to the log files in
764 the server. Affected file silcd/protocol.c.
766 * Add SKE's reference counter even if calling the completion
767 callback manually. Otherwise it goes negative, although it
768 does not cause any problems. The affected file is
769 lib/silcske/silcske.c.
771 * Remove the client entry with short timeout after giving the
772 KILL command. Affected file lib/silcclient/command.c.
774 * Fixed to send error reply in WHOIS and IDENTIFY commands in
775 case all found clients are already disconnected (WHOWAS would
776 found them) in the server. Affected file silcd/command.c.
778 * Update the last_receive (time of last data received) to be
779 updated only when received private or channel message so that
780 the idle time showed in WHOIS makes more sense.
782 * Added boolean field `valid' in to the SilcClientEntry in the
783 client library to indicate whether the entry is valid or not.
784 This fixes the nickname change bug on channel when changing
785 the nickname to be same than the old (like nick to Nick) the
786 nickname formatter doesn't set the new nick anymore to Nick@host.
787 Affected file lib/silcclient/idlist.[ch].
789 * Now actually fixed the nickname changing on disconnection.
790 Added new function silc_change_nick to the Irssi SILC Client.
791 Affected file irssi/src/silc/core/client_ops.c,
792 irssi/src/silc/core/silc-nicklist.[ch].
794 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Check that the public key exists in the GETKEY command before
797 trying to encode it. Affected file silcd/command.c.
799 * Print some notifications on received public keys with GETKEY
800 command in the Irssi SILC Client. Affected files are
801 irssi/src/fe-common/silc/module-formats.[ch],
802 irssi/src/silc/core/client_ops.c.
804 * Use IDENTIFY command to resolve the server information in the
805 GETKEY command instead of INFO command. Affected file
806 lib/silcclient/command.c.
808 * All command reply functions in the client library now calls
809 the pending command reply callbacks even if an error has
810 occurred. The server has done this a long time and now it was
811 time to move the client library to this as well. Now all
812 errors can be delivered back to the pending command reply
813 callbacks if necessary. Affected files are
814 lib/silcclient/command[_reply].[ch].
816 * Change the nickname on disconnection back to the username
817 because in reconnect the server will enforce it to it anyway.
818 Affected file irssi/src/silc/core/silc-servers.c.
820 * Fixed a config file parsing bug in the Irssi SILC client.
821 Affected file irssi/src/silc/core/clientconfig.c.
823 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
825 * When printing the channel mode on JOIN, verify that the
826 channel key and channel's HMAC are valid. Affected file
827 irssi/src/silc/core/client_ops.c.
829 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
832 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
833 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
835 * Removed channel key rekey task deleting from the function
836 silc_server_save_channel_key. Affected file silcd/server.c.
837 Added explicit timeout task context instead that is used to
838 delete the task if we are registering a new task before the
839 new task has elapsed.
841 * When channel key rekey occurs the client library now saves
842 the old channel key for a short period of time (10 seconds) and
843 is able to use it in case some is still sending channel
844 messages encrypted with the old key after the rekey. Affected
845 file lib/silcclient/[idlist.h|client_channel.c].
847 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Added check to the silc_server_new_id_real to not accept
850 new ID if it is the sender's own ID. Affected file is
851 silcd/packet_receive.c.
853 * Assure that we do not announce ourself or the one we've
854 sending our announcements when we're router and are announcing
855 servers to our primary router. Affected file silcd/server.c.
857 * Fixed silc_server_command_identify_check_client to assemble
858 correct WHOIS packet. It send corrupted WHOIS packet and
859 caused problem with router to router connections. Affected
860 file silcd/command.c.
862 Fixed also silc_server_command_whois_check the same way
863 as for the IDENTIFY command.
865 * Added new SilcIDListStatus to the server in the SilcIDListData
866 structure. The status now includes the current status of
867 the entry (like registered, resolved etc.). Affected file
868 silcd/idlist.[ch]. Defined a bunch of different status types
869 as well. This replaced the old boolean registered field as well.
871 Added resolve_cmd_ident field to the SilcClientEntry structure
872 too so that if the entry is for example being resolved so
873 another command may attach to the same pending command reply
874 without requiring to resolve the same entry again. This concept
875 should optimize the WHOIS and the IDENTIFY resolving under
876 heavy load by taking away unnecessary resolving for entries
877 that are being resolved already.
879 Added support for adding multiple pending commands for one
880 command idenfier. Affected file silcd/command[_reply].[ch].
882 * Fixed WHOIS and IDENTIFY save to remove the cache entry
883 before deleting the data. Otherwise the hash table will have
884 freed data in comparison functions. Affected file is
885 silcd/command_reply.c.
887 * Fixed silc_idlist_replace_client_id to add the new entry to
888 the cache with NULL nickname. Otherwise there will be invalid
889 memory as the nickname after the nickname is freed. Affected
890 file silcd/packet_receive.c.
892 * Fixed the silc_idlist_get_clients_by_hash. The entries was
893 saved into wrong slots because the previous number of entries
894 was not taken into account. Affected file silcd/idlist.c.
895 Fixed same thing in silc_idlist_get_clients_by_nickname too.
897 * If we are router and we receive JOIN notify to a channel that
898 does not have any users then notified client is marked as the
899 channel founder, as it is it. The affected file is
900 silcd/packet_receive.c
902 * Added to the extended hash table API's table_del_*ext functions
903 the destructor as argument too, so that the caller can decide
904 which destructor to use or whether to use destructor at all.
905 Affected file lib/silcutil/silchashtable.[ch].
907 * Fixed ID Cache purging. It actually deleted the entries from
908 the hash table after the data was freed. The hash table ended
909 up comparing freed memory. The affected file is
910 lib/silccore/silcidcache.c.
912 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Fixed Irssi SILC client's KILL command's HELP syntax.
916 * The USERS command now resolves the detailed user information
917 if the userinfo field is missing. Affected file is
918 lib/silcclient/command_reply.c.
920 * Do not print error in silc_file_read if the read file does
921 not exist. Just silently return NULL. Affected file is
922 lib/silcutil/silcutil.c.
924 * Fixed the silc_log_output to not wine about NULL filename
925 and to not create some bogus " " filename. Affected file is
926 lib/silcutil/silclog.c.
928 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed various printing bugs on the user interface in the
931 Irssi SILC Client. Minor changes that were forgotten from
934 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Fixed the configure.in.pre and the compilation and distribution
937 environment to support the new autoconf 2.52. That version is
938 now required to compile the CVS trunk.
940 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Renamed function silc_parse_nickname to silc_parse_userfqdn
943 to generally parse user@fqdn format strings. Affected file
944 lib/silcutil/silcutil.c.
946 * Added nickname_format and nickname_force_format fields to the
947 SilcClientParams structure. The first one defines the format
948 for the nicknames that the library will enforce if the receives
949 multiple same nicknames. The second one is boolean value and
950 can be used to force the library to always enforce the format
951 to the nicknames regardles whether there are multiple nicknames
952 or not. This configurable formatting was employed to flexibly
953 support accessing multiple nicknames from the user interface.
954 The userinterface can now set the nicknames to what ever format
955 they prefer. Affected file lib/silcclient/silcapi.h.
957 Added function silc_client_nickname_format to the file
958 lib/silcclient/idlist.c. It performs the nickname formatting.
960 Added new field `hostname´ to the SilcClientEntry context.
961 It holds the hostname of the client. Affected file is
962 lib/silcclient/idlist.h.
964 * Irssi SILC Client sets the nicknames in nick@hostn format.
965 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
966 irssi/src/silc/core/silc-core.c.
968 The WHOIS printing now also shows both the real nickname and
969 the formatted nickname so that user knows how to access the
970 user if there are multiple same nicknames cached. Affected
971 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
972 printing formatting too to take the hostname now as a separate
973 argument. The Affected file is
974 irssi/src/fe-common/silc/modules-formats.[ch].
976 * Changed the silc_client_get_clients_local to accept the formatted
977 nickname as argument. It accepts the real nickname too but the
978 formatted nickname can be used to find the true entry from
979 multiple entries. Affected file lib/silcclient/silcapi.h and
980 lib/silcclient/idlist.c.
982 * Added nickname_format_parse field to the SilcClientParams.
983 It is a callback function provided by the application to parse
984 the nickname out of the formatted nickname string. The library
985 calls it to get the nickname from the formatted string. Since
986 the application generally knows better the format of the nickname
987 string it parses it instead of the library, even though library
988 encodes the formatted string. If the callback function is not
989 provided then the library will use the string as is. The
990 affected file is lib/silcclient/silcapi.h.
992 * All the nickname strings passed to the client library in
993 commands are now expected to be formatted nickname strings.
994 If the command does not support the formatted nickname string
995 it will assume that the sent string is the actual nickname.
996 Affected file lib/silcclient/command.c.
998 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1000 * Added public key authentication support to OPER and SILCOPER
1001 commands in the client library. Affected file is
1002 lib/silcclient/command.c.
1004 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Changed the get_auth_methdod client operation to be asynchronous.
1007 It can be async if the application resolves the authentication
1008 method from the server during the negotiation. Added new
1009 SilcGetAuthMeth completion callback that the application will
1010 call after resolving the authentication method.
1012 Added function silc_client_request_authentication_method that
1013 the application can use to resolve the authentication method
1014 from the server. Added also SilcConnectionAuthRequest callback
1015 that the library will call after the server has replied. The
1016 application can call this function if it does not know the
1017 current authentication method.
1019 Affected files are lib/silcclient/client.c and
1020 lib/silcclient/silcapi.h.
1022 * The Irssi SILC client now automatically resolves the authentication
1023 method incase any configuration information is not present (and
1024 currently there never is). The affected file is
1025 irssi/src/silc/core/client_ops.c.
1027 * Fixed public key authentication from the client library.
1028 Affected file lib/silcclient/protocol.c. Changed also the
1029 protocol specification about the public key authentication in
1030 the connection authentication protocol. The actual data to be
1031 signed is now computed with a hash function before signing.
1033 * Fixed the public key authentication from the server as well.
1034 Affected file silcd/protocol.c.
1036 * Removed the mlock()'s from the memory allocation routines.
1037 Affected file lib/silcutil/silcmemory.c. The ./configure does
1038 not check anymore for the mlock(). Affected file is
1041 * Fixed USERS command in server to allow the execution of the
1042 command for private and secret channels if the client sending
1043 the command is on the channel. Affected file silcd/command.c.
1045 * Fixed silc_client_get_clients_local to return the clients
1046 count correctly. It could return wrong value. Affected file
1047 lib/silcclient/idlist.c.
1049 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1052 types. The assembler optimizations seemed not to like 64-bit
1053 data types. The assmebler optimizations thus are now enabled
1054 also for BSD systems as opposed to only enable them for Linux.
1056 * Do not check for threads at all on BSD systems. Affected
1057 file configure.in.pre.
1059 * Removed -n and -h options from the Irssi SILC Client since
1060 they are not used in silc.
1062 * Fixed the prime generation to assure that the first digit
1063 of the generated random number is not zero since our conversion
1064 routines does not like number strings that starts with zero
1065 digit. If zero digit is seen the random number is regenerated.
1066 This caused some corrupted RSA keys when the zero first digit
1067 was met. Affected file lib/silcmath/silcprimegen.c.
1069 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Fixed WIN32 configuration in the ./configure script.
1072 Fixed to include xti.h on environments that has it.
1073 Patches by Carsten Ilchmann and andrew.
1075 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Changed the silc_id_create_client_id to be collision
1078 resistant. It is now assured that there cannot be created
1079 two same client ID's. I suspect that some weird bugs in
1080 the server were actually caused by duplicate Client IDs.
1081 Affected file silcd/serverid.[ch]. A router receiving
1082 new ID now also assures and informs the sending server
1083 if the ID caused collision.
1085 * Changed the silc_id_create_channel_id to also assure that
1086 there are no collisions.
1088 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1090 * Statement about ignoring the Mutual Authentication flag when
1091 performing rekey with PFS was a bit misleading. It is ignored
1092 if it was set in the initial negotiation, it cannot be even
1093 set in the rekey. Fixed in the ke-auth draft. Started the
1094 new versions of the protocol drafts in the doc/.
1096 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Fixed a bug in silc_client_command_identify_save when saving
1099 new channel information. The channel name was no duplicated
1100 and caused crash on exit. Affected file is
1101 lib/silcclient/command_reply.c.
1103 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Fixed the getkey command handling in the server. Send just
1106 empty OK reply to the sender if the key could not be fetched
1107 (but everything else was ok, like the key just was not available).
1108 Changed the public key parameter to optional in the protocol
1109 specs so that empty OK reply can be sent. Affected file
1112 Added a message to Irssi SILC client to tell to user if the
1113 server did not return a public key.
1115 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1117 * Fixed a channel key regeneration bug. It registered new
1118 timeout tasks exponentially until all system resources were
1119 used. Affected file silcd/server.c.
1121 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Added the SILC Document generator to the scripts/silcdoc.
1124 It can be used to generate the Toolkit Reference Manual out
1125 of the source tree. Internally it will also use the RoboDoc
1126 generator now imported in util/robodoc.
1128 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Added couple of return's in rekey protocol if error orccurred
1131 during the protocol. The execution must be terminated.
1132 Affected file silcd/protocol.c. Also, terminate the protocol
1133 always with timeout.
1135 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1137 * The client's Client ID was created initally from the wrong
1138 nickname (it could have been in format nick@host) in the
1139 silc_server_new_client. Affected file silcd/packet_receive.c
1141 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Added some SILC_LOG_ERROR's to various error conditions
1144 if client could not be added to ID cache. Affected files
1145 silcd/packet_receive.c and silcd/server.c.
1147 * When client's sock->user_data is freed, NULL also the
1148 client->router and client->connection pointers. Added check
1149 for these pointers being NULL to various places around the
1150 code. Affected file silcd/server.c.
1152 * Added client->data.registered == TRUE checks to various
1153 places around the code to assure that unregistered client's
1154 are not handled when it is not allowed. Affected file
1157 * Added `bool registered' fields to all
1158 silc_idlist_[server|client]_get_* routines to indicate whether
1159 the fetched client needs to be registered or not. Affected
1160 file silcd/idlist.[ch].
1162 * Add your own entry as registered to the ID cache in the
1163 server. Affected file server.c.
1165 * Fixed a bug in silc_server_new_server. The SilcServer was
1166 set as the new server's context instead of SilcServerEntry.
1167 This naturally caused some weird bugs.
1169 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Do not delete the channel rekey task when adding it
1172 for in silc_server_create_channel_key.
1174 * Changed the silc_server_create_channel_key to return
1175 TRUE or FALSE to indicate the success of the channel key
1178 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Fixed MSVC++ project files and added missing files to

1183 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Do not add TCP_NODELAY flag if the operating system
1186 does not have it defined. Affected files are
1187 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1189 * Fixed buffer overflow from Irssi SILC Client. Affected
1190 file irssi/src/fe-common/core/themes.c.
1192 * Fixed double free in client library in the file
1193 lib/silcclient/client.c when disconnecting from server.
1195 * Applied double free patch from cras to Irssi SILC client.
1196 Affected files irssi/src/core/[modules/expandos].c
1198 * Fixed the disconnection handling to Irssi SILC Client.
1199 The application must call silc_client_close_connection
1200 in ops->connect client operation in case of failure of
1201 the connection. Affected file is
1202 irssi/src/silc/core/client_ops.c.
1204 * Do not set sock->protocol to NULL in the function
1205 silc_client_close_connection after executing the protocol's
1206 final callback since the sock might not be valid anymore.
1207 Affected file lib/silcclient/client.c.
1209 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1211 * Do not enable SILC_THREADS if the linking with libpthread
1212 did not happen. Affected file configure.in.pre.
1214 * Added notion to protocol specification that server must
1215 verify the sent authentication payload with CMODE when
1216 setting the channel founder key. Implemented it to the
1217 server. Affected file silcd/command.c.
1219 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * Added _EXTRA_DIST SILC distribution variable to the
1222 distributions file. It is used to conditionally add extra
1223 files or directories to the specific distribution. Affected
1224 files ./prepare, Makefile.am.pre and distributions.
1226 Removed the `_' from the start of the distribution names.
1229 * Added README.WIN32 for instructions to compile the Toolkit
1232 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1234 * Fixed a double free in disconnection in the server. Affected
1235 file is silcd/server.c.
1237 * Fixed the lib/silcske/groups.c to work now also with GMP
1238 MP library. The string conversion did not work when using
1239 specific base and the base is indicated in the string as well.
1241 * Created win32/ directory which now includes MSVC++ specific
1242 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1243 It will appear only in the toolkit distribution
1245 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Changed the key material distribution function in case when
1248 the hash output is too short. The data is now concatenated
1249 a bit differently than it used to. Made the change to the
1250 SKE protocol specification.
1252 * Added better GMP detection to configure.in.pre. A patch
1255 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Fixed a minor bug in SKE that might cause some problem on
1258 some platforms. Affected file lib/silcske/silcske.c.
1260 * Added the cookie checking for initiator in the SKE. It checks
1261 that the responder returns the sent cookie unmodified. The
1262 affected file is lib/silcske/silcske.c. Added new SKE
1263 error type INVALID_COOKIE that can be sent during the
1264 negotiation. Fixed some memory leaks as well.
1266 * Added the "invalid cookie" error message to Irssi SILC client's
1269 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1271 * Added `task_max' field to the SilcClientParams to indicate
1272 the maximum tasks the scheduler can handle. If set to zero,
1273 default values are used. Affected file lib/silcclient/silcapi.h.
1275 * Fixed memory leaks in silc_client_close_connection. Affected
1276 file lib/silcclient/client.c.
1278 * Added silc_client_del_client_entry to client library to free
1279 all memory of given client entry. Affected file is
1280 lib/silcclient/idlist.[ch].
1282 * Added new functions silc_client_del_channel and
1283 silc_client_del_server to delete channel and server entries.
1284 Affected file lib/silcclient/[silcapi.h/idlist.c].
1286 * Removed silc_client_del_client_by_id from silcapi.h.
1288 * Fixed the INFO command to return the server's own info
1289 correctly when querying by Server ID. Affected file is
1292 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Removed the non-blocking settings in WIN32 code in the
1295 silc_sock_[read/write] and added SleepEx instead. Affected
1296 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1297 of input data is now checked with FIONREAD and ioctlsocket.
1299 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Call silc_schedule_task_del_by_context in the
1302 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1303 Affected file lib/silccore/silcprotocol.c.
1305 * Call silc_protocol_cancel for active protocols in the
1306 silc_server_close_connection if the funtion
1307 silc_server_free_sock_user_data has not been called.
1308 Affected file silcd/server.c.
1310 * Generic tasks cannot be deleted using the del_by_fd
1311 task deleting function since generic tasks does not match
1312 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1314 * Added a notion to SILCOPER help file that the SILCOPER works
1315 only on router server, not on normal server.
1317 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Added for WIN32 support for the new scheduler as well.
1320 Affected file lib/silcutil/win32/silcwin32schedule.c.
1322 * Fixed the SHA1 implementation to work on various platforms.
1324 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1327 API. It is part of the scheduler now. Everything else is
1328 as previously but some functions has changed their names.
1329 Checkout the lib/silcutil/silcschedule.h for the interface.
1330 Updated all applications to use the new interface. Affected
1331 files are lib/silcutil/silcschedule.[ch].
1333 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Found a bug in the SKE implementation. The HASH value,
1336 specified by the protocol, was not computed correctly. The
1337 public key of the responder was not added to the computation
1338 even though it is mandatory. Affected file lib/silcske/silcske.c.
1339 This unfortunately causes incompatibilities with older
1340 clients and servers.
1342 * Added WIN32 specific network init and uninit functions:
1343 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1344 the Winsock2. Affected file lib/silcutil/silcnet.h and
1345 lib/silcutil/win32/silcwin32net.c.
1347 * Set the socket always to nonblocking mode on WIN32 after
1348 reading data or writing data. Affected file is
1349 lib/silcutil/win32/silcwin32sockconn.c.
1351 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1353 * Fixed various compilation problems under WIN32. Affected
1354 files lib/silcutil/win32/silcwin32thread.c and
1355 lib/silcutil/win32/silcwin32schedule.c.
1357 * Removed all _internal.h #includes from public header
1358 files. Internal headers must never be included from
1361 Removed also the lib/silcske/payload_internal.h file.
1363 * All include files that may be needed (public and some others
1364 included by the public headers) by application developers are
1365 now copied to the ./includes directory. It does not copy any
1366 internal headers. Affected file Makefile.defines.pre and all
1367 Makefile.am's under lib/ and subdirs.
1369 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Do not change the ~/.silc directory's permissions automatically.
1372 Affected file irssi/src/silc/core/clientutil.c.
1374 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Do not cancel the protocol in silc_server_close_connection
1377 it might cause recursion. Now cancelled in the function
1378 silc_server_free_sock_user_data. Affected file silcd/server.c.
1380 * Fixed the silc_server_remove_clients_by_server to regenerate
1381 the channel keys correctly finally. Added also new function
1382 silc_server_remove_clients_channels to actually do it.
1383 Affected file silcd/server.c.
1385 * Fixed the silc_server_new_channel to not crash by giving
1386 wrong router to the new channel. Affected file is
1387 silcd/packet_receive.c.
1389 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1392 which is given as argument to the silc_client_alloc now.
1393 It can be used to configure the client and set various parameters
1394 that affect the function of the client.
1396 * The USERS command in server did not check whether the channel
1397 is private or secret. Affected file silcd/command.c.
1399 * Added new argument to the USERS command in protocol specification.
1400 The USERS command now can take the channel name as argument
1401 as well. Added support for this in client and server and
1402 updated the protocol specs.
1404 * Completed the GETKEY command in client. It can be now used
1405 to fetch also servers public key not only some clients.
1406 Affected files lib/silcclient/command[_reply].c.
1408 * Added silc_client_get_server to return server entry by the
1409 server name. Affected files lib/silcclient/silcapi.h and
1412 * Redefined the IDENTIFY command in protocol specification to be
1413 more generic. It now can be used to query information about
1414 any entity in the SILC Network, including clients, servers and
1415 channels. The query may be based either the entity's name
1416 or the ID. Added support for this in both client and server.
1418 Affected files silcd/command.c and lib/silcclient/command.c
1419 and command_reply.c.
1421 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1422 the _from_client and _from_server functions. Affected file
1425 * Added silc_client_get_channel_by_id_resolve to the file
1426 lib/silcclient/silcapi.h to resolve channel information by
1427 its ID. Added also silc_client_get_channel_by_id that
1428 does not resolve it from the server.
1430 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Added SilcServerEntry context into the client library
1433 to represent one server. The INFO command now allocates
1434 these to save the resolved server info. For now on the
1435 client library will also keep information about servers,
1436 connected and resolved with INFO.
1438 The INFO command now allocates the SilcServerEntry context
1439 and saves the server info there. The COMMAND_REPLY in
1440 the INFO now returns the parameters to application in
1441 same order as defined in the protocol specification.
1443 The entries are cached in the client->server_cache.
1445 * The INFO command is now issued after received the Client ID
1446 from the server. Affected file lib/silcclient/client.c.
1448 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1449 to the application as the mode changer might be server.
1450 It is guaranteed that NULL is not returned anymore to the
1451 application. Affected file lib/silcclient/client_notify.c.
1453 The ID Type is now also passed to the application so that
1454 it can check whether the returned entry is SilcClientEntry
1457 Added new function silc_client_get_server_by_id to return
1458 the server entry by ID. Affected files are the
1459 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1461 * Do not create the channel in the Irssi SILC Client when issuing
1462 the JOIN command but when received the sucessful JOIN command
1463 reply. Otherwise the channel might get created even though we
1464 could not join it. The Affected file is
1465 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1467 * Fixed a channel joining bug in router. The router must also
1468 check the channel modes, invite and ban lists etc. when serving
1469 the JOIN command sent by normal server. Affected file is
1470 silcd/command.c. The router now resolves the client's
1471 information from the server who sent the JOIN command if it
1472 does not know it, and processes the JOIN command only after
1475 * Changed the SilcCommandCb to take new argument; void *context2.
1476 Affected file lib/silccore/silccommand.h
1478 The second argument in the command callbacks in the server now
1479 includes the SilcServerCommandReplyContext if the command was
1480 called as pending command callback from the command reply.
1481 Otherwise it is NULL. When called as pending the status of the
1482 command reply will be checked and if it was erronous the
1483 error will be sent to the original sender of the command.
1484 This way the client always receives the error messages even
1485 though the server was actually the one who received the error
1486 when it resent the command to router, for example. Affected
1487 files silcd/command[_reply].[ch].
1489 * Fixed sending WHOWAS command's error message to client if
1490 the requested client could not be found. It was missing.
1493 * Changed the CMODE and CUMODE commands reply arguments in the
1494 protocol specification. The Channel ID is now sent in both
1495 of the commands to identify the channel. Implemented this
1496 new feature to the client and server. Affected files
1497 lib/silcclient/command_reply.c and silcd/command.c.
1499 * Made better checks for invite and ban lists in the JOIN
1500 command in server. Affected file silcd/command.c.
1502 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * The server now performs the incoming host IP/DNS lookup
1505 using the silc_socket_host_lookup and thus does not block
1506 the server anymore. Affected file silcd/server.c.
1508 * Completed the multi-thread support for SILC Scheduler in
1509 the lib/silcutil/silcschedule.c.
1511 * Fixed the configure.in.pre to detect the pthread correctly
1514 * Fixed a deadlock in silc_task_queue_wakeup in the file
1515 lib/silcutil/silctask.c.
1517 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Added new function silc_schedule_wakeup that is used in
1520 multi-threaded environment to wakeup the main thread's
1521 schduler. It needs to be used when a thread adds a new task
1522 or removes a task from task queues. After waking up, the
1523 scheduler will detect the task queue changes. If threads
1524 support is not compiled in this function has no effect.
1525 Implemented the wakeup mechanism to both Unix and WIN32
1526 systems. Affected files are lib/silcutil/silcschedule.[ch],
1527 lib/silcutil/unix/silcunixschedule.c and the
1528 lib/silcutil/win32/silcwin32schedule.c.
1530 * Added new function silc_task_queue_wakeup to wakeup the
1531 scheduler by the specified task queue. Affected file
1532 lib/silcutil/silctask.[ch].
1534 * The silc_socket_host_lookup_start now wakes up the scheduler
1535 after adding the timeout task. Affected file is
1536 lib/silcutil/silcsockconn.c.
1538 * The silc_socket_host_lookup is synchronous now if the threads
1539 support is not compiled in. However, the callback is still
1540 called asyncronously through the scheduler, anyway. Affected
1541 file lib/silcutil/silcsockconn.c.
1543 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Added new function silc_socket_host_lookup to perform
1546 asynchronous IP and FQDN lookups for the socket connection.
1547 Affected files lib/silcutil/silcsockconn.[ch].
1549 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1552 that may or may not compile the mutex support in.
1554 Changed the silc_mutex_alloc interface. It allocates the
1555 mutex now to the sent pointer and returns TRUE or FALSE.
1557 Affected file lib/silcutil/silcmutex.h.
1559 * Wrote the SILC Task Queue interface to support multi-threads.
1560 Affected file lib/silcutil/silctask.[ch].
1562 * Wrote the SILC Scheduler to support multi-threads. Affected
1563 file lib/silcutil/silcschedule.c.
1565 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1568 in lib/silcutil/win32/.
1570 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Defined SILC Mutex API and SILC Thread API and implemented
1573 them for Unix. Affected files are
1574 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1575 lib/silcutil/unix/silcunixmutex.c and
1576 lib/silcutil/unix/silcunixthread.c.
1578 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Fixed the silc_server_remove_clients_by_server's channel
1581 key re-generation. The hash table handling was incorrect
1582 and would not work with many channels. Affected file is
1585 * Fixed some memory leaks around the server code.
1587 * Rewrote the silc_server_get_users_on_channel to support IPv6
1588 based Client ID's. Affected file silcd/server.c.
1590 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1591 specification. However, a separate document must be written
1592 to define the detailed signing procedure and the payload
1593 associated with the flag. Defined the flag to the
1594 lib/silccore/silcchannel.h as well.
1596 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Changed the dynamic tables to static size tables in the
1599 lib/silccrypt/silchmac.c.
1601 * Removed GCC dependencies from the code. A patch by cras.
1603 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * Do not show the error "Error receiving packet bla bla"
1606 in server if it really was not an error (-2 means that reading
1607 is pending). Affected file silcd/server.c.
1609 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Fixed a possible crash in silc_server_remove_clients_by_server
1612 in silcd/server.c. Fixed there also some memory leaks.
1614 * Fixed the silc_idlist_replace_client_id. It could replace
1615 wrong key in the hash table. Affected file silcd/idlist.c.
1617 * Do not check whether there are global users on the channel
1618 if the channel->global_users is FALSE. Affected functions
1619 silc_server_remove_from_one_channel and
1620 silc_server_remove_from_channels in silcd/server.c. Also,
1621 do not check if the removed client is local as we can be
1622 sure that global client was not removed from the channel
1623 and checking for global users is not needed.
1625 * The silc_server_remove_clients_by_server now re-generates
1626 the channel keys correctly for those channels that had
1627 clients removed from them. Affected file silcd/server.c.
1629 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Found the reason of random crashes in the server. We weren't
1632 ignoring the SIGPIPE signal (which can be sent in write())
1633 and it crashed the server. Affected file silcd/silcd.c.
1635 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Assure that sock->user_data is not NULL in the function
1638 silc_server_packet_send in silcd/packet_send.c.
1640 * Disconnect the remote connection if it could not be added
1641 to any ID lists in the server. The affected file is
1644 * Check in silc_server_packet_send[_real/dest] that the
1645 socket is not disconnecting and ignore the data if it is.
1646 Affected file silcd/packet_send.c.
1648 * Define inline to __inline on native WIN32 compilation.
1649 Affected file includes/silcwin32.h.
1651 * Added some explicit type casts for inline code since MSVC
1652 require them. Affected files lib/silcutil/silcbuffer.h,
1653 lib/trq/silcdlist.h and lib/trq/silclist.h.
1655 * Print warning in log files from now on if the packet
1656 decryption fails. Affected file silcd/server.c.
1658 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * Changed the `say' client operation's interface to accept
1661 new `type' argument to indicate the type of the message sent
1662 by the library. The application may filter the library's
1663 messages according the type. The affected file is the
1664 lib/silcclient/silcapi.h.
1666 * Added two new functions to lib/silcclient/silcapi.h:
1667 silc_client_del_client and silc_client_del_client_by_id.
1668 Affected file lib/silcclient/idlist.c.
1670 * Moved the clientincludes.h from includes/ to silc/ and
1671 serverincludes.h from includes/ to silcd/.
1673 * The modes for the CMODE and CUMODE are now passed as
1674 uint32 for application with COMMAND_REPLY. The affected
1675 file is lib/silcclient/command_reply.c.
1677 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * /WHOIS without arguments shows client's own information.
1680 Affected file lib/silcclient/command.c.
1682 * Changed PING to not accept any arguments. The specs
1683 says that client can ping only the connected server so
1684 requiring an argument is not needed. Affected file is
1685 lib/silcclient/command.c.
1687 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Fixed a fatal bug in private message sending and reception
1690 encryption and decryption when using private message keys.
1691 The implementation was incorrect and did not follow the
1692 specification. It causd that some of the message were
1693 lost since it did not use the sending and receiving keys
1694 as the protocol suggests. This has been fixed and will cause
1695 incompatibilities with older clients when sending private
1696 message encrypted with private message keys. Affected files
1697 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1698 and various other in Irssi SILC Client.
1700 Added `responder' boolean argument to the functions
1701 silc_client_add_private_message_key[_ske] to indicate when
1702 the key is added as responder or initiator of the key
1705 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Removed the silc_ske_check_version function and created
1708 a SilcSKECheckVersion callback. Added also a function
1709 silc_ske_set_callbacks that is now used to set all SKE
1710 callbacks. The callback functions are not given to
1711 the SKE functions anymore, but this function is used to
1714 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1716 * Added `silc_version' argument to the silc_client_alloc
1717 to define the version of the application for the library.
1718 The library will use the version string to compare it
1719 against the remote host's (usually a server) version
1720 string. Affected file lib/silcclient/silcapi.h
1722 * Added the KE protocol context to Key Agreement context
1723 in client library so that we can abort the SKE if it
1724 is in process when we get timeout. Affected file is
1725 lib/silcclient/client_keyagr.c.
1727 * Do not resolve the client ID forever if it returns in the
1728 first time that such client does not exist. This was done
1729 for example with private message. Affected file is
1730 lib/silcclient/client_prvmsg.c.
1732 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1734 * Do not add regex.h for WIN32. The affected file
1735 includes/silcincludes.h.
1737 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1738 not work yet 100%. It generates the DLL's automatically
1739 when compiling with --with-win32 under cygwin.
1741 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * lib/contrib/regex.c is not compiled on WIN32.
1745 * Added silc_net_get_socket_opt function to the
1746 lib/silcutil/silcnet.h.
1748 * Added includes/silcwin32.h for WIN32 specific includes
1751 * Do not use ptime structure or any of the posix process
1752 functions on WIN32 in lib/silccrypt/silrng.c.
1754 * Added silc_gettimeofday to provide generic function
1755 for struct timeval on all platforms. Added the function
1756 to lib/silcutil/silcutil.h.
1758 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1761 library as they clearly belong there. As a plus side we
1762 can make the actual socket connection routines platform
1765 Added also new generic function silc_socket_read and
1766 silc_socket_write (that used to be silc_packet_[read/write].
1767 The implementation of these are platform specific.
1769 * Added WIN32 specific routines of silc_socket_[read/write]
1770 to lib/silcutil/win32/silcwin32sockconn.c.
1772 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Added preliminary support for native WIN32 compilation under
1775 cygwin (using the -mno-cygwin option for GCC) to the
1776 ./configure.in.pre. The --with-win32 now prepares the
1777 compilation for native WIN32.
1779 * Rewrote the SILC Scheduler interface in the file
1780 lib/silcutil/silcschedule.h. The scheduler is now context
1781 based and does not have anymore any global static scheduler.
1782 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1783 and created lib/silcutil/win32 directory for WIN32 based
1786 * Added Unix specific network routines to the
1787 lib/silcutil/unix/silcunixnet.c and the old
1788 lib/silcutil/silcnet.c includes now only generic routines.
1790 Added WIN32 specific network routines to the
1791 lib/silcutil/win32/silcwin32net.c.
1793 * Added Unix specific utility functions from the
1794 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1796 * Added WIN32 SILC Scheduler to the file
1797 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1800 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Do not handle JOIN notify in the server if the target client
1803 is not registered (idata->registered == FALSE). The affected
1804 file is silcd/packet_receive.c.
1806 * Update the nickrec->founder in event_cumode in the Irssi SILC
1807 client. Affected file irssi/src/silc/core/silc-channels.c.
1809 * Fixed the CUMODE_CHANGE notify handling in the server when
1810 server and router are announcing their clients on channels.
1811 Now the mode changes are saved and notified correctly. The
1812 affected file is /silcd/packet_receive.c.
1814 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1815 They really did not replace the cache entry in the ID Cache.
1816 Now they do that. Affected file silcd/idlist.c.
1818 * Fixed the KICK notify handling in the Irssi SILC client to
1819 update the channel records so that the kicked client does not
1820 appear to be on the channel. The affected file is
1821 irssi/src/silc/core/silc-channels.c.
1823 * Always update the conn->current_channel when executing command
1824 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1826 * Fixed the KILL notify handling in Irssi SILC client to remove
1827 the killed client on all channels.
1829 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Fixed the silc_parse_command_line to remove extra spaces
1832 from the start and end of the arguments. Affected file is
1833 lib/silcutil/silcutil.c.
1835 * Cancel and free any active protocol in the function
1836 silc_server_close_connection. Affected file silcd/server.c.
1838 * Cancel and free any active protocol in the function
1839 silc_client_close_connction. Affected file is
1840 lib/silcclient/client.c.
1842 * Do not execute the KILL command for clients that are in
1843 history (ie. they are not in the network). Affected file is
1846 * Fixed KILL notify handling, client does not crash anymore.
1847 Affected file irssi/src/silc/core/silc-channels.c.
1849 * Reduced the default packet buffer size from 2048 to 1024 in
1850 lib/silccore/silcpacket.c.
1852 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1853 counter to the SKE context that is incresed when the SKE library
1854 performs async operation outside the library. If the outside
1855 process frees the SKE context and FREED status will be set
1856 and the library will detect after the sync operation that the
1857 libary is freed. The affected files are
1858 lib/silcske/silcske[_status].[ch].
1860 * Resolve the client entry information in the function
1861 silc_client_channel_message to assure that NULL pointer is not
1862 passed as client entry to the application. */
1864 * Fixed the task timeout calculation to assure that there is
1865 never negative timeouts. The affected file is
1866 lib/silcutil/silcschedule.c.
1868 * Fixed the channel user mode notification sending in server.
1869 It was sent point-to-point to the router (or to server by router)
1870 but it needs to be destined to a channel. The routines now
1871 supports sending the channel user mode notifys to the channels
1872 when announcing clients and channels. Affected files are
1873 silcd/server.c and silcd/packet_receive.c.
1875 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1876 It did not actually replace the old channel entry in the cache.
1877 Affected file lib/silcclient/client_notify.c.
1879 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1881 * Fixed a possible crash in silc_packet_send_prepare. It now
1882 assures always that there is enough space in the buffer and
1883 at the tail area of the buffer (for MAC).
1885 Fixed the inbound buffer reallocation in silc_packet_read.
1886 It was old code and did not handle the reallocation correctly.
1889 The affected file is lib/silccore/silcpacket.c.
1891 * Fixed buffer overflow in silc_parse_nickname in the file
1892 lib/silcutil/silcutil.c.
1894 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * make install generates new server keys only if there is not
1899 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1901 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1902 Added check that if the NOREPLY is set then we will not send
1903 the away message. This avoids infinite loop of away messages
1904 if both clients are away. The affected file is
1905 lib/silcclient/client_prvmsg.c.
1907 * Fixed client crash if /NICK was given without arguments.
1908 Affected file lib/silcclient/command.c.
1910 * Server does not send the invite list in INVITE command back
1911 to the client if the list was not altered. Added this notion
1912 to the protocol spec as well. Affected file silcd/command.c.
1914 Fixed possible crash in INVITE command by checking the
1915 value of silc_server_get_client_route command.
1917 * Fixed the INVITE notify type handling. The arguments are now
1918 taken in correct order and client does not crash. The affected
1919 file is irssi/src/silc/core/silc-channels.c.
1921 Removed the "Inviting xxx to channel" message from the
1922 client library away and let the application handle it.
1923 Affected file lib/silcclient/command.c. Added that message
1924 to Irssi SILC client's message formats.
1926 * Fixed CMODE command crash in client. It now checks the
1927 amount of arguments correctly and does not crash. The affected
1928 file is lib/silcclient/command.c.
1930 * Do not create new channel automatically in silc_channels_join
1931 but check whether the channel by that name already exists.
1932 Affected file irssi/silc/core/silc-channels.c.
1934 * Do not send the SERVER_SIGNOFF to router if the disconnected
1935 entity was the router. Affected file silcd/server.c.
1937 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1938 SILC client as it was missing from there.
1940 Added the handling of the KICK notify to the Irssi SILC client
1941 as it was missing. Added "you have been kicked" message to
1942 Irssi SILC client's message modules formats.
1944 Added the handing of the KILL notify to the Irssi SILC client
1945 as it was missing. Added the kill message module formats
1948 The affected file is irssi/src/silc/core/silc-channels.c.
1950 * The router did not save the channel mode the server announced.
1951 Affected file silcd/packet_receive.c.
1953 * Fixed a possible crash in INFO command in server. If the
1954 server did not provide the server info it crashed. Affected
1955 file silcd/command.c.
1957 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Fixed the GETKEY command in the server to check also the
1960 global list. Otherwise the GETKEY would not work correctly
1961 in normal SILC server. Affected file silcd/command.c.
1963 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1965 * Fixed GETKEY crash, it crashed if the command did not succseed.
1967 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1969 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1970 is now real and not just an macro interface to GMP.
1972 Removed the entire GMP from the source tree and imported new
1973 NSS MPI library instead. Reason for removing GMP is that it is
1974 extremely large and compiles extremely slow. The NSS MPI
1975 is only a few files and compiles in less than 10 seconds.
1976 The speed is also about the same as GMP. The MPI is imported
1977 to lib/silcmath/mpi.
1979 If the system has GMP installed we will still use the GMP.
1980 If it is not then the NSS MPI will be compiled.
1982 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Merged a long nickname (127 characters long) crash bugfix from
1985 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1987 * Merged a freed memory reference bugfix from Irssi CVS tree.
1988 Affected file irssi/src/core/commands.c.
1990 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Added the server's public key sving and verification to the
1993 server when performing the SKE. This was missing and the
1994 remote server's (or router's) public key was accepted without
1995 checking whether we have it previously or trust it at all.
1996 Affected file silcd/protocol.c.
1998 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Check in the silc_server_timeout_remote if protocol is active
2001 and make sure that the protocol's final callback is called so
2002 that all memory if freed. Affected file silcd/server.c.
2004 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * silc_server_whois_send_reply crashed the server if the nickname
2007 was 127 characters long. Affected file silcd/command.c.
2009 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Added sanity check to the silc_server_new_client. If the hostname
2012 is provided inside username then check that the provided hostname
2013 really is the same as the resolved one. If the hostname was not
2014 resolved then check it from the public key. Affected file is
2015 silcd/packet_receive.c.
2017 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2018 if the server disconnected us and the connection is not valid
2019 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2021 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2022 the library to the lib/silcutil/silcutil.[ch].
2024 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Close log file after open. Affected file
2027 lib/silcutil/silclog.c.
2029 * Check whether sock == NULL in silc_client_send_packet and return
2030 if it is. Affected file lib/silcclient/silcclient.c.
2032 * Check rec->entry == NULL in the Irssi SILC Client before
2033 sending the channel message. Affecte file is
2034 irssi/src/silc/core/silc-servers.c.
2036 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Merged a splitted window bugfix from Irssi CVS tree. The
2039 affected file is irssi/src/fe-text/textbuffer-view.c.
2041 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2042 It did not print nickname.
2044 * Improved the distributions system a bit.
2046 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2049 irssi/src/fe-text/gui-window.c.
2051 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2052 to in-active server. The affected file is
2053 irssi/src/silc/core/client_ops.c.
2055 * Resolve the client in USERS command reply if the entry does
2056 not have username resolved. The affected file is
2057 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2058 command to WHOIS command to really resolve stuff. The USERS
2059 is not used any more in any critical section so WHOIS can
2060 be used even though it might be slower than IDENTIFY.
2062 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2065 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Changed the protocol API a bit more consistent in the
2068 lib/silccore/silcprotocol.[ch].
2070 * Changed the following headers to ROBODoc format:
2072 lib/silccore/silcpayload.h
2073 lib/silccore/silcprotocol.h
2074 lib/silccore/silcsockconn.h
2076 All core library headers are now formatted.
2078 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Fixed a bug in Irssi SILC client; do not show that you are
2081 server/router operator if you really are not. Affected file is
2082 irssi/src/silc/core/client_ops.c.
2084 * Renamed silc_command_free_payload to silc_command_payload_free.
2085 Affected file lib/silccore/silccommand.h
2087 * Added silcmath.h to include the prototoypes of various routines
2088 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2091 * Changed the following headers to ROBODoc format:
2093 lib/silccore/silcchannel.h
2094 lib/silccore/silccommand.h
2095 lib/silccore/silcid.h
2096 lib/silccore/silcidcache.h
2097 lib/silccore/silcmode.h
2098 lib/silccore/silcnotify.h
2099 lib/silccore/silcpacket.h
2100 lib/silcmath/silcmath.h
2102 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Added checking to the server code not to start the server if
2105 ciphers and stuff are not configured properly. Affected files
2106 silcd/serverconfig.[h] and silcd/server.c.
2108 * Changed the layout of the header files of the public interfaces
2109 in the SILC libraries. The new layout supports ROBODoc
2110 documentation tool (and some others) so that it is easy to create
2111 a library reference manual. All the other headers and source
2112 code must still follow the CodingStyle document. Also source
2113 code must not include these ROBODoc stuffs, only the headers.
2114 Furthermore, all public interface headers must now be named
2115 by using `silc' prefix, example: silcapi.h, silccipher.h.
2116 Some files were renamed due to this. All the other headers
2117 must not be used as public interfaces. I will update the
2118 CodingStyle document later. Changed following headers, so far:
2120 lib/silcclient/silcapi.h
2121 lib/silccore/silcauth.h
2122 lib/silccore/silcprivate.h
2123 lib/silccrypt/silcdh.h
2125 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * Removed silc_client_packet_send_flush from the client library
2130 as it is not needed. Affected file lib/silcclient/client.[ch].
2132 * Added printing of message of unresolved authentication method
2133 to the Irssi SILC client. Added it to the module formats.
2134 Removed the same message from the client library.
2136 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Added new distribution feature, DISTLABEL. Every distribution
2139 can define own preprocessor label that can be used in the
2140 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2141 file distributions, acconfig.h.pre and prepare.
2143 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Added Makefile.defines_int to include the actual definitions
2146 for Makefile.defines.in. Tested the new distribution system,
2147 created distributions and tested installation.
2149 * Added AWAY message printing to the Irssi SILC client. Added
2150 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2152 * Added SCONNECT command to call the SILC's CONNECT command.
2153 Cannot use CONNECT directly since Irssi uses that internally.
2154 Affected file irssi/src/silc/core/silc-servers.c.
2156 Added ACTION local command. It is same as ME command but takes
2157 the channel as mandatory argument.
2159 Rewrote some of the Irssi's help files to suite for SILC
2162 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Added Makefile.defines[.in] that should for now on be included
2165 in all Makefile.am file in the source tree. That file includes
2166 all common compilation definitions for SILC source tree.
2168 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Minor changes to the ./prepare script to change the package
2171 name according the distribution name to the configure.in.
2173 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Created new distribution system. Added file `distributions'
2176 that defines all the distributions that can be created out of
2177 the SILC source tree. The ./prepare script now reads that
2178 file to determine how to prepare the distributions. The
2179 first argument to the ./prepare is the name of the distribution
2180 and second is the version of the distribution. If given
2181 without arguments it creates the default (toolkit) distribution
2182 with the default version (defined in ./prepare).
2184 All Makefile.am files that are subject to the distributions
2185 are now named as Makefile.am.pre. These are ./Makefile.am
2186 and lib/Makefile.am. Others may be changed later.
2188 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Added invite list, ban list, some key management and connection
2191 error message printing to module formats in the Irssi SILC client.
2193 * Added new silc_client_set_away_message to set the away message
2194 that is back to the person who sent private message. The
2195 affected file lib/silcclient/silcapi.h and the
2196 lib/silcclient/client_prvmsg.c.
2198 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Fixed the private message sending in the Irssi SILC client,
2201 added local command KEY to the Irssi SILC client.
2203 Added key management and key agreement message formats to the
2204 irssi/src/fe-common/silc/module-formats.[ch].
2206 Added USERS (alias WHO) printing, server/router operator
2207 indication and LIST command printing to the module formats.
2209 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Fixed channel joining notify handling, cumode notify handling
2212 from Irssi SILC client.
2214 * Added SILC specific module-formats to the Irssi SILC client so
2215 that SILC specific message hilighting, colors etc is possible.
2216 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2218 Added channel mode, channel user mode, actions, notices,
2219 whois and whowas printing to the the module-formats.c.
2221 * Fixed a bug in channel deletion in the server. The channel
2222 is not left to the cache even if the channel founder auth mode
2223 is set when there are no users anymore on the channel. Affected
2224 file silcd/server.c.
2226 * The silc_net_localhost now resolves the entire hostname including
2227 the domain name. Affected file lib/silcutil/silcnet.c.
2229 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Changed the ask_passphrase client operation to be ascynchronous.
2232 It has now a completion callback and a context that the
2233 application must call after it has got the passphrase from
2234 the user. Affected files lib/silcclient/silcapi.h,
2235 lib/silcclient/protocol.c, lib/silcclient/command.c and
2238 Added SilcAskPassphrase callback that the application calls
2239 to deliver the passphrase to the library.
2241 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2242 The public key verification and especially a certificate
2243 verification is asynchronous procedure.
2245 Added new SILC_SKE_STATUS_PENDING status to indicate the
2246 request is pending and a callback will be called to finalize
2249 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2250 indicate that remote end did not send its public key (or
2251 certificate), even though we require it. Added check for this
2252 condition in the SKE. This was a security bug, now fixed.
2254 Defined new SilcSKEVerifyCbCompletion callback that is called
2255 when the verification process is completed.
2257 The affected files lib/silcske/silcske_status.h and
2258 lib/silcske/silcske.[ch].
2260 * Changed the verify_public_key client operation to be async
2261 as well. Defined SilcVerifyPublicKey callback that is used to
2262 indicate the success of the public key verification process.
2264 Changed the server and client to use the new async client
2267 * Changed the Irssi SILC client's internal scheduler to be called
2268 twice as many times as it used to be. As a result the client
2269 should be a bit faster now. Affected file is
2270 irssi/src/silc/core/silc-core.c.
2272 * Added support to Irssi SILC client of asynchronous public key
2273 verification and passphrase inquiry. Affected file is
2274 irssi/src/silc/core/silc-core.c.
2276 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Do not say "You have left channel %s" in client library.
2279 Moved it to the application. Affected files are
2280 lib/silcclient/command.c and silc/client_ops.c.
2282 * Fixed silc_client_get_clients. Command context was not
2283 duplicated and was freed memory in the callback. Affected
2284 file lib/silcclient/idlist.c.
2286 * Do not say "you are now talking..." on JOIN command in the
2287 client library. The appliation must handle it.
2289 * Do not say ".. changed topic to" in command reply in the
2290 client libary. The application must handle it.
2292 * Fixed TOPIC command sending in the client library.
2294 * Fixed a memory leak in silc_client_command_free in the file
2295 lib/silcclient/command.c.
2297 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Imported a modified version of Irssi client to the source tree.
2300 The Irssi will be used to create a new client called
2301 Irssi SILC. Imported to irssi/.
2303 Added silc_core_init_finish function to the Irssi. Affected
2304 file irssi/configure.in.
2306 A lot changes in the Makefile.ams around the irssi tree.
2308 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Do not rehash if the new size is same as the old size of the
2311 hash table, in the silc_hash_table_rehash*. The affected file
2312 lib/silcutil/silchashtable.c.
2314 * Replaced hash_table_del_by_context calls from the server
2315 (when channel->user_list and client->channels) to the
2316 hash_table_del as it is sufficient and faster.
2318 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Added silc_hash_table_list, silc_hash_table_get and the
2321 SilcHashTableList structure to provide an alternative way to
2322 traverse the hash table. The affected files are
2323 lib/silcutil/silchashtable.[ch].
2325 * Changed the server's idlist routines to use the hash table
2326 routines to optimize the code.
2328 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Replaced the client entry's `channel' list and channel entry's
2331 `user_list' list to hash tables for optimized lookup. Changed
2332 the code to use the hash table interface around the code.
2333 Affected file lib/silcd/idlist.[ch].
2335 * Added `auto_rehash' boolean argument to the function
2336 silc_hash_table_alloc to indicate whether the hash table should
2337 auto-rehash when it thinks is appropriate time. It will
2338 increase the hash table size if the there is twice as much
2339 entries in the table than the size of the table, and will
2340 decrease the size if there are twice as less entries than
2341 the size of the table.
2343 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2347 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * silc_idcache_purge_by_context deletes the entry now by context
2350 as it is supposed to do. Affected file lib/silccore/idcache.c.
2352 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2353 client is not anymore valid (WHOWAS givens the info) and not
2354 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2356 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Removed the `data' and `data_len' arguments from the ID Cache
2359 interfaces and added `name' argument. ID Cache does not handle
2360 anymore the binary data only a names associated with given ID.
2362 * When hashing a Client ID with silc_hash_id the entire ID is
2363 not hashed anymore, instead only the hash of the Client ID is
2364 hashed. This way we can access the Client ID from the cache
2365 with Client ID but with the hash of the ID (which is a hash of
2366 the nickname) as well without any difference in performance.
2368 Added also silc_idcache_find_by_id_one_ext to do one on one
2369 searching when we have the actual ID. Added also function
2370 silc_hash_client_id_compare. The affected files are
2371 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2373 * When hashing the name associated with a ID it is always done
2374 in lowercase. This way we can access the cache without worrying
2375 about case-sensitivity, even though, for example nicknames are
2378 * Fixed a bug in server with channel message sending. It put
2379 wrong ID type as destination ID. The affected file
2380 silcd/packet_send.c.
2382 * silc_idcache_del_by_context now deletes from all hash tables
2383 by context. Affected file lib/silccore/idcache.c.
2385 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2387 * Changed the client library to use the new ID Cache interface.
2388 Changes around the source tree.
2390 * Added silc_hash_table_rehash_ext to rehash with specific
2391 hash function. Affected file lib/silcutil/silchashtable.[ch].
2393 * Added silc_hash_string_compare to compare two strings in the
2394 hash table. Affected file lib/silcutil/silcutil.[ch].
2396 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Added new function silc_idcache_del_by_context into the
2399 lib/silccore/idcache.[ch].
2401 * Changed the server's ID list routines to use the new ID Cache
2402 interface. Changes around the source tree.
2404 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Added silc_hash_table_del[_by_context]_ext functions in to the
2407 lib/silcutil/silchashtable.[ch].
2409 Removed silc_hash_table_find_all* routines and added new
2410 silc_hash_table_find_foreach to replace them.
2412 Added silc_hash_table_replace_ext function as extended
2413 replacing function. Separated the simple hash table interface
2414 from the extended hash table interface in the file
2415 lib/silcutil/silchashtable.h.
2417 * Fixed minor bugs and changed it to use some of the new
2418 hash table functions in lib/silccore/idcache.c
2420 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Added new function silc_hash_table_find_all to return all keys
2423 in the hash table by the specified key. As the hash table is
2424 collision resistant it also makes it possible to have several
2425 duplicate keys in the hash table. This function may be used to
2426 find all of the keys from the hash.
2428 Added user_context arguments to the SilcHashFunction,
2429 SilcHashCompare and SilcHashDestructor to deliver user specified
2432 Added new fuctions silc_hash_table_find[_all]_ext to do
2433 extended lookup with specified hash and compare functions and
2434 specified user contexts.
2436 Added new function silc_hash_table_add_ext to add the key
2437 with specified hash function and user context.
2439 Added new function silc_hash_table_foreach to traverse all
2440 entrys in the hash table. Added SilcHashForeach callback
2443 Added new function silc_hash_table_del_by_context to delete
2444 the entry only if the context associated with the key matches.
2446 Affected files are lib/silcutil/silchashtable.[ch].
2448 * Removed silc_hash_[server/client/channel]_id and added just
2449 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2450 silc_hash_id_compare to compare two ID's using as the hash table
2451 comparison function. Added also silc_hash_data to hash
2452 binary data and silc_hash_data_compare to compare it.
2454 * Removed silc_idlist_find_client_by_hash as it is not needed
2455 anymore. Affected file silcd/idlist.[ch].
2457 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2458 to use internally the SilcHashTable. The new ID Cache is a lot
2459 faster than the old one. Some of the ID Cache interface was also
2460 rewritten and obsolete and stupid functions were removed.
2462 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Added entry_count field to the SilcHashTable to keep the number
2465 of the entries in the table. Implemented the function
2466 silc_hash_table_rehash. Added new function
2467 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2469 Fixed a minor bug in silc_hash_table_free.
2471 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2472 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2473 into the lib/silcutil/silcutil.[ch].
2475 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Implemented a collision resistant hash table into the
2478 lib/silcutil/silchashtable[ch]. See the header and the source
2479 for the SilcHashTable API.
2481 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Merged dotconf version 1.0.2 into lib/dotconf.
2485 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Do not compile anything in lib/silcsim/* if the SIM support
2488 is not enabled. The tree should now compile without problems
2491 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Compiled the SILC under cygwin. Compiled and tested briefly
2494 without problems. More tests needed. The SIMs didn't compile
2497 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2499 * Fixed possible crash in silc_get_username in the
2500 lib/silcutil/silcutil.c.
2502 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Fixed a va_arg in silc/client_ops.c.
2506 * Oops, RC5 routines were named AES and caused some problems
2507 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2509 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Added new SilcIDIP structure into the lib/silccore/id.h and
2512 replaced the old `ip' fields from all SILC ID's to that type.
2513 This is a step towards IPv6 support.
2515 The silc_id_get_len takes now the ID as an extra argument.
2516 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2517 both IPv4 and IPv6 based ID's.
2519 The affected files are lib/silccore/id.[ch] and other files
2520 around the tree using these routines.
2522 * Removed the ID length arguments in server from various
2523 silc_server_send_notify_* routines -> they are not needed
2526 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Fixed memory leak in silc_encode_pem_file in the file
2529 lib/silcutil/silcutil.c.
2531 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Check minor version as well in the SKE. Affected files are
2534 silcd/protocol.c and lib/silcclient/protocol.c.
2536 * Added --identifier option to the server so that an identifier
2537 can be when creating the public key for the server. Affected
2538 file is silcd/silcd.c.
2540 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2541 lib/silccrypt/silcpkcs.c.
2543 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Register default ciphers and stuff when using -C option with
2546 the server. Affected file sildc/silcd.c.
2548 * Put back the servers public key filename format, it is better
2549 than the new one. For now, the client keys are saved with the
2550 new filename format. The affected file silc/client_ops.c.
2552 * Implemented the Cipher API for the rest of the ciphers that
2553 did not implement it or implemented it the wrong way.
2555 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Register default ciphers and stuff when using the -S option
2558 in the client. Affected file silc/silc.c. Same also when
2559 creating new key pair with -C option.
2561 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Fixed the silc_verify_public_key client operation function to
2564 save the public keys differently. The fingerprint is now
2565 used as filename and not the hostname. This way also the
2566 client keys are saved uniquely and not with hostnames. The
2567 affected file is silc/client_ops.c.
2569 * Trimmed the silc_hash_fingerprint function to remove extra
2570 whitespaces from the end of the fingerprint. The affected
2571 file is lib/silccrypt/silchash.c.
2575 * Added silc_cipher_register_default function to register all
2576 default ciphers. It can be used when configuration files
2577 does not exist and the application does not want any specific
2578 ciphers in any specific order.
2580 The SilcDList is now used as silc_cipher_list dynamically
2581 allocated cipher list. Removed the static list all together
2582 and now all ciphers must be allocated to the dynamic list.
2583 The silc_cipher_alloc routine was changed to check only the
2586 All silc_cipher_* routines that used to return int returns
2589 The affected files lib/silccrypt/silccrypt.[ch].
2591 * The same thing was done to silc_hash_* as for silc_cipher_*
2592 routines. Affected files lib/silccrypt/silchash.[ch].
2594 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2595 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2596 Added also silc_pkcs_[un]register[_default] functions.
2597 Removed the data_context from the PKCS API.
2599 * Added silc_hmac_register_default function to register default
2600 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2601 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2602 to unregister all hmacs at once.
2604 * Register the default ciphers, hash functions, PKCSs and HMACs
2605 if client's configuration file does not exist. The affected
2608 * The client did not load the hash functions from the SIM
2609 modules at all. Added support for this. Affected file is
2610 silc/clientconfig.c.
2612 * When decoding public key with silc_pkcs_public_key_decode, check
2613 the supported algorithm only if PKCS are registered. Affected
2614 file lib/silccrypt/silcpkcs.c. The same was done with the
2615 silc_pkcs_private_key_decode.
2617 * Fixed the SILC List routines to keep the list always in order.
2618 It used to change the list's order when traversing the list but
2619 not it preserves the order. Affected file lib/trq/silclist.h.
2621 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Added the client library to use the SilcSocketConnection's
2624 reference counter (by silc_socket_dup) to prevent the bug that
2625 the socket object may be freed underneath async operation.
2627 * The name resolv library checking fixes in the configure.in.pre.
2630 * Created new version of the protocol drafts for future
2631 development. The -03 drafts are the ones that will be changed
2632 in the trunk now and the -02 will remain as they are.
2634 * Send list of CUMODE notifys to the router when announcing
2635 the channel users to the router. Affected file silcd/server.c.
2636 If the router receiving channel founder CUMODE for a channel
2637 that already has channel founder it will send CUMODE notify
2638 to the sender to remove the channel founder rights from the
2639 announced client. Affected file silcd/packet_receive.c.
2641 * The CUMODE notify may now use Server ID as well as the entity
2642 who changes the mode. Updated protocool specs.
2644 * Updated INSTALL and README files.
2646 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * New web pages in the http://silc.pspt.fi. The pages was
2653 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Implemented the [DenyConnectin] config section in the server.
2656 Added silc_server_config_denied_conn to check whether incoming
2657 connection is denied. Affected file silcd/serverconfig.[ch].
2659 * Do not check the ports when checking the incoming configuration
2660 data if the port is 0, meaning any. Affected file is
2661 silcd/serverconfig.c.
2663 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2665 * Fixed buffer overflow in silc_string_compare in the file
2666 lib/silcutil/silcutil.c.
2668 * Fixed double free in silc_server_command_leave in the file
2671 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Fixed the version checking in the server. Affected file is
2676 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Fixed the configuration data fetching when accepting new
2679 connections in the server. Affected file silcd/server.c.
2681 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Added `sender_entry' argument to the function
2684 silc_server_packet_relay_to_channel so that we can check
2685 whether some destination actually belongs to the same route
2686 the sender belongs (ie, we must not resend the packet to the
2687 sender). Affected file silcd/packet_send.[ch].
2689 * Added `servername' field to the SilcClientEntry in the server
2690 to hold the name of the server where client is from. Affected
2691 file is silcd/idlist.h.
2693 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * Moved the channel message encrypting in the router betwen
2696 router connections from silc_server_channel_message to the
2697 silc_server_packet_relay_to_channel since we want to check
2698 whether we have anybody channel before encrypting anything.
2699 Affected files silcd/packet_[receive/send].c.
2701 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Fixed the [AdminConnection] server config section to support
2704 multiple entries. Affected file silcd/serverconfig.c.
2706 * Added support into the server to check the validity of the
2707 incoming connection before executing any KE or authentication
2710 * The connection configuration is now saved to the KE and
2711 connection auth protocol contexts and not fetched anymore in
2712 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2714 * The local hosts listenning address and port is also resolved
2715 now when starting the server. We want to have the socket object
2716 to include the real address and port for the listener. Added
2717 new function silc_net_check_local_by_sock into the files
2718 lib/silcutil/silcnet.[ch].
2720 * Fixed a broadcast bug in server -> do not broadcast if we
2723 * Fixed a routing bug. Do not route broadcast packets ever.
2724 Broadcast packets must be processed always and not routed since
2725 they may be destined to some other host than yourself and thus
2726 would get routed without no good reason. Affected file is
2729 * Added function silc_server_config_is_primary_route to check
2730 whether primary router connection has been configured (a router
2731 configuration that we are initiating). If there is not, we
2732 will assume that there is only two routers in the SILC network
2733 and we will use the incoming router connection as our primary
2734 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2736 * Changed the order of the broadcasting. Broadcast _after_ the
2737 packet has been processed not before. Affected file is
2740 * Fixed a [ClientConnection] parsing bug. The port was never
2741 parsed correctly thus resulting to port 0. Affected file
2742 silcd/serverconfig.c.
2744 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2745 argument and did not set the broadcast packet flag. Affected
2746 file silcd/packet_send.c. Fixed same bug in the function
2747 silc_server_send_notify as well.
2749 * If we receive NEW_ID packet for our own ID in the server, ignore
2752 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * Removed the nickname from the Private Message Payload.
2757 Updated the code and the protocol specs.
2759 * Updated protocol specs for submitting to the IETF.
2761 * Tweaked the Random Number Generator a bit. Affected file
2762 lib/silccrypt/silcrng.c. Exported a new function
2763 silc_rng_[global]_add_noise which can be used to add more
2766 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Do not parse packets with different timeout when protocol
2769 is active -> may cause problem with rekey. Affected file
2772 * When server receives signoff notify it must not create
2773 new channel key if the client is on any channels since the
2774 sender of the signoff notify will create it.
2776 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Added printing of error messages during SKE protocol from the
2779 failure packet sent by server during SKE. Affected file
2782 * Removed the client's failure_callback handling with timeout
2783 and handle it immediately when received.
2785 * The SKE library returned wrong type in SUCCESS and FAILURE
2786 packets. They must be 32 bit MSB not 16 bit MSB.
2788 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Ok, rewrote the logic of the re-key and now it seems to work.
2791 I tested it on high traffic with frequent re-keys without
2792 problems. Added hmac_receive (and renamed hmac to hmac_send)
2793 in SilcClientConnection in lib/silcclient/client.h and
2794 in SilcIDListData in silcd/idlist.h. Also, removed the
2795 SilcPacketParserContext's cipher and hmac fields as they are
2796 not needed anymore and actually caused some problems when
2797 the ciphers and hmac's changed underneath the packet parser.
2799 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * If re-key protocol is active then process the incoming packets
2802 synchronously since we must assure that icoming packets encrypted
2803 with the old key is processed before the new keys is set to
2804 use. This is true other packets than for REKEY packets.
2805 Affected file silcd/server.c. The same was done to client library
2806 as well, affected file lib/silcclient/client.c.
2808 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Fixed bug in client and server to accept the force send if
2811 the packet is send from silc_[server/client]_packet_process
2812 function. Otherwise the packets are never delivered, oops.
2814 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Disable force sending of packets when REKEY protocol is active.
2817 We must assure that no packet is sent directly when rekey is
2818 performed. All packets must be sent through packet queue.
2819 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2820 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2821 function is silc_[server/client]_packet_send_real to check
2824 * Replaced the SIM paths from example config files to
2825 /usr/local/modules. Also, make install creates now
2826 /usr/local/silc/logs directory to hold all the SILC server
2829 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Made the configure.in.pre work on Solaris. Patch by salo.
2833 * Made all ciphers compatible with non-x86 machines. Defined
2834 CBC mode macros into lib/silccrypt/ciphers_def.h.
2836 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Fixed the make install.
2840 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * When MAC computation fails the silc_packet_decrypt returned 0
2843 even though it was supposed to return -1. Fixed this. The
2844 affected file is lib/silccore/silcpacket.c.
2846 * Do not replace the config files in /etc/silc (in make install)
2847 if they already exist. Affected file ./Makefile.am.
2849 * Do not send re-key packets immediately but through packet queue.
2850 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2852 * Changed silc_net_check_host_by_sock to return FALSE if the
2853 IP/DNS could not be resolved. Though, it returns the IP address
2854 now even if it could not resolve it (but returns also FALSE).
2855 Affected file lib/silcutil/silcnet.[ch].
2857 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Added silc_pkcs_decode_identifier to decode the public key's
2860 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2861 Added also silc_pkcs_free_identifier. Added also new context
2862 SilcPublicKeyIdentifier.
2864 * Added -S option to the silc client. It is used to dump the
2865 contents of the specified public key file.
2867 * Changed the PKCS api to return the public key length when
2868 setting the public key.
2870 * Fixed a fatal bug in the public and private key file loading.
2871 Affected file lib/silccrypt/silcpkcs.c.
2873 * Execute the packet parsing for client with zero (0) timeout
2874 if the protocol is active. Affected file silcd/server.c.
2876 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Made the key generation options to the silcd program. Added
2879 -C option, equivalent to client's option.
2881 * Added new [ServerKeys] config section to the server. It
2882 configures the server's public and private key.
2884 * Defined generic Public Key Payload into the protocol
2885 specification to send specific type of public keys and
2888 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2889 public key or certificate.
2891 * Implemented the GETKEY command to the server and to the
2892 client library and on user interface.
2894 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Made preliminary `make install' work.
2898 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Added SilcServerRekey context into silcd/idlist.h.
2902 * Added the PFS support as defined in the specification to the
2903 SKE protocol. Affected files lib/silcske/*.c.
2905 * Added `ske_group' field to the SilcServerRekey context to hold
2906 the number of the SKE group that is used with PFS in re-key.
2907 Affected file silcd/idlist.h.
2909 * Added PFS re-key support to the server. Affected file is
2912 * Added silc_protocol_cancel to cancel execution of the next
2913 state of the protocol. Affected file is
2914 lib/silccore/silcprotocol.[ch].
2916 * Added the re-key support with and without PFS to the client
2917 library. Re-key is performed once in an hour, by default.
2919 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2920 Added silc_client_rekey_callback and silc_client_rekey_final.
2921 Affected files are lib/silcclient/protocol.[ch] and
2922 lib/silcclient/client.[ch].
2924 * Removed the `hmac_key' and `hmac_key_len' fields from the
2925 SilcClientConnection structure; not needed. Affected file is
2926 lib/silcclient/client.h.
2930 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Do not ask whether user wants to use the negotiated private key
2933 for private messages, just use it. Affected file is
2934 silc/local_command.c.
2936 * Added `send_enc_key' and `enc_key_len' fields to the
2937 SilcIDListData structure since they are needed in the re-key
2938 phase. Affected file is silcd/idlist.[ch].
2940 * Implemented the simple re-key protocol into the server.
2941 Affected files silcd/server.c and silcd/protocol.[ch]. The
2942 re-key will be performed once in an hour, by default.
2944 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2945 Added silc_server_rekey, silc_server_rekey_callback and
2946 silc_server_rekey_final.
2948 * Removed Tunneled flag from the protocol. Updated the code
2949 and the specifications.
2951 * Adde `pfs' field to the SilcIDListData to indicate whether
2952 the PFS is to be performed in the re-key. Affected file is
2955 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2958 int64 of at least the xintXX size. If void * is less that 4
2959 bytes uint32 * will be used. Defined bool as boolean.
2961 * Changed _ALL_ unsigned long and unsigned int to uint32,
2962 unsgined short to uint16 in the source tree.
2964 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2965 not handle clients that has entry->data.registered == FALSE.
2966 They are not in the network anymore. Affected file is
2969 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Implemented the sending of the SERVER_SIGNOFF notify in the
2972 server. Affected file is silcd/server.c.
2974 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2975 Added also silc_notify_payload_encode_args into the
2976 lib/silccore/silcnotify.[ch].
2978 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2979 Affected file silcd/packet_receive.c.
2981 * Implemented the SERVER_SIGNOFF notify handling in the client
2982 library. Affected file lib/silcclient/client_notify.c. Also,
2983 implemnted the printing of the SERVER_SIGNOFF info to the
2984 application. Affected file silc/client_ops.c.
2986 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2987 if the deleting was successful. Affected file silcd/idlist.[ch].
2989 * Added support for public key authentication in the connection
2990 authentication protocol in the client library. Affected file
2991 lib/silcclient/protocol.c.
2993 * Changed the server's silc_idlist_get_clients_by_* interface
2994 to support already allocated array so that new entries may be
2995 added to pre-allocated array. Affected file silcd/idlist.[ch].
2996 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2997 and command replies.
2999 * All command reply functions in the server now calls the
3000 pending command callback even if error occured. This way the
3001 error will be delivered to the client as well. Affected files
3002 silcd/command.c and silcd/command_reply.c.
3004 * Fixed INFO command to return local server's info if no server
3005 was provided. Affected file lib/silcclient/command.c.
3007 * Removed RESTART command for good. Updated the code and the
3010 * Rewrote parts of the task system. It is a bit simpler now.
3011 Removed unsued task priorities. The affected files are
3012 lib/silcutil/silctask.[ch].
3014 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Moved the USERS printing from the library to the application.
3017 Affected files lib/silcclient/command.c and silc/client_ops.c.
3019 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Added channel key re-key support. The re-key is perfomed
3024 only by the router and is done once in an hour. Added `rekey'
3025 field to the SilcChannelEntry in the server. Affected files
3026 silcd/server.c and silcd/idlist.h.
3028 * Added silc_task_unregister_by_context into the file
3029 lib/silcutil/silctask.[ch].
3031 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Added SILC_UMODE_GONE mode to indicate when the client is not
3034 present in the SILC network. Added also support to the local
3035 command AWAY that will set this mode. Added support of showing
3036 "xxx is gone" in WHOIS command. The USERS command shows the
3037 gone status as well.
3039 * Fixed setting server and router operator privileges in the
3040 server's UMODE command. Affected file silcd/command.c.
3042 * Merged the SKE KE1 and KE2 payloads into one payload. The
3043 new KE payload is equivalent to the old KE2 payload.
3045 Cleaned up the SKE Start Payload parsing. It now uses the
3046 simple buffer unformatting to do the parsing. A lot faster
3049 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3050 to the SKE that is used to indicate whether both of the SKE
3051 parties should perform authentication. By default only the
3052 responder performs authentication. By setting this flag also
3053 the initiator must do authentication. By default it is unset
3054 since in normal SKE case, client to server connection, only
3055 the responder should do authentication. When doing SKE between
3056 two clients both should perform authentication. Updated the
3057 code and the protocol specs.
3059 * A little fix to IDENTIFY command in the server. Search the
3060 client first by hash not nickname. Affected file is
3063 * Fixed the silc_client_close_connection to support closing
3064 the client to client connections wihtout deleting too much
3065 data. Affected file lib/silcclient/client.c.
3067 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3068 are received if protocol used to be active but is not anymore
3069 the application would crash due to NULL pointer dereference.
3070 Affected files silcd/server.c and lib/silcclient/client.c.
3072 * Added `hash' field to the SilcClientConnection to include
3073 the hash function negotiated in the SKE protocol.
3075 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3076 to set the channel founder authentication data. A client can
3077 claim the founder rights later by providing the authentication
3078 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3079 This way the channel founder can regain the channel founder
3080 privileges even it is left the channel. This works only on
3081 local server and the client must be connected to the same
3082 server to be able to regain the founder rights. Updated the
3083 protocol specs accordingly.
3085 Added support to the CMODE command in the client to set the
3086 founder auth data. Read the README to see how to set it.
3088 Added support to the CUMODE command to claim the founder
3089 rights. Read the README to see how to do it.
3091 Added support for the founder authentication to the Channel
3092 Entry in the server. Affected file silcd/idlist.h.
3094 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3095 server's CMODE command. Affected file silcd/command.c.
3097 * Added the following new functions into lib/silccore/silcauth.[ch]:
3098 silc_auth_get_method and silc_auth_get_data.
3100 * The server now saves the remote hosts public key to the
3101 SilcIDListData pointer. Affected file silcd/protocol.c.
3103 * The normal server now does not remove the channel entry from
3104 the cache if the founder authentication data is set. It used
3105 to remove it if the founder was the last one on the channel on
3106 the server and left the channel. The auth data is saved and
3107 if the channel is re-joined later the old entry is used with
3108 the old auth data. Affected files silcd/command_reply.c and
3111 * Removed the `pkcs' field from the SilcIDListData structure
3112 in the server; it is not used. Affected file silcd/idlist.h.
3114 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Fixed packet processing on slow links. Partial packets were
3117 never re-processed because the incoming data buffer was cleared
3118 by the application. Application must not directly clear the
3119 sock->inbuf, the packet processing routines handle it. Fixed
3120 this in client library and in server.
3122 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Fixed the WHOIS and IDENTIFY send reply function to really
3125 check whether to send list or just one entry. Affected file
3128 * Cleaned up the LEAVE command's channel key distribution. The
3129 affected file silcd/command.c.
3131 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3132 can enforce the channel mode as well. In that case the ID
3133 includes the ID of the server. The code now enforces the
3134 mode change if the router have different mode than the server.
3136 * The notify client operation with CMODE_CHANGE notify can now
3137 return NULL client_entry pointer if the CMODE was not changed
3138 by client. Application must check for this.
3140 * Added <Server ID> argument to INFO command to support server
3141 info fetching by Server ID.
3143 * Added silc_server_announce_get_channel_users to get assembled
3144 packets of channel users of the specified channel. Affected
3145 file silcd/server.[ch].
3147 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3148 was freed underneath the ID Cache.
3150 * Re-announce clients when the server received CHANNEL_CHANGE
3151 notify from the router. Affected file silcd/packet_send.c.
3153 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3156 crashed since it did not handle the fact that there is no cipher
3157 called "3" and didn't check the error condition. Now fixed.
3159 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3160 flag. It can be used to send message requests.
3162 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Implemented the RESTART command in the client.
3166 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3167 notice type messages. Added notice printing to the user
3170 * The channel keys are not re-generated if the channel's mode
3171 is PRIVKEY, ie private key on the channel exists. Affected
3172 files silcd/server.c and silcd/command.c.
3174 * Fixed a little bug in channel message delivery when channel
3175 private keys are set in the server. Affected file is
3176 silcd/packet_send.c.
3178 * Changed the setting on channel->on_channel = TRUE from the
3179 silc_client_save_channel_key to the JOIN command reply. The
3180 key payload is not received if the private channel key is set.
3181 Affected file lib/silcclient/command_reply.c and the
3182 lib/silcclient/client_channel.c.
3184 * When the CMODE_CHANGE notify is sent and the channel private
3185 key mode is removed the channel key must be re-generated in
3186 other cells as well. Added this support for the router in the
3187 silcd/packet_receive.c.
3189 * Added new local command NOTICE to send notice message on
3190 channel. Affected file silc/local_command.[ch].
3192 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Added new local command ME to the client. It is used to send
3195 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3196 some action. Affected file silc/local_command.[ch].
3198 * Changed channel_message and private_message client operations
3199 to deliver the message flags to the application. Added also
3200 the `flags' arguments to the silc_client_send_channel_message
3201 and silc_client_send_private_message functions. Affected file
3204 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Redefined the Private Message Payload to support private message
3207 keys and to support the new private message flags. Updated
3208 the protocol specs. Flags makes it possible to have for example
3209 CTCP style messages.
3211 * Added new type SilcPrivateMessagePayload and defined an API
3212 for it in the lib/silcclient/silcprivate.[ch].
3214 * Tested private message private keys successfully. Tested the
3215 private message key set, unset and list commands with the new
3218 * Redefined the Channel Message Payload to include the channel
3219 message flags (equal with private message flags) to support
3220 for example CTCP style messages.
3222 * Defined some of the message (for channel and private message)
3223 flags. Updated the protocol specs and added the flags to the
3224 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3226 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Added SilcKeyAgreementStatus type to the key agreement routines
3229 to indicate the current status and error if one occured.
3230 The status types are defined in the lib/silcclient/silcapi.h.
3232 * Added new local command KEY that is used to set and unset private
3233 keys for channels, set and unset private keys for private messages
3234 with remote clients and to send key agreement requests and
3235 negotiate the key agreement protocol with remote client. The
3236 key agreement is supported only to negotiate private message keys,
3237 it currently cannot be used to negotiate private keys for channels,
3238 as it is not convenient for that purpose.
3240 * Fixed a minor pending callback setting bug in the function
3241 silc_client_get_client_by_id_resolve, now the function works.
3242 Affected file lib/silcclient/idlist.c.
3244 * Added function silc_net_get_local_port to get local bound
3245 port by socket. Added to lib/silcutil/silcnet.[ch].
3247 * Added `sockets' and `sockets_count' fields to the SilcClient
3248 object. They hold the sockets of the listenning sockets in
3249 the client. Listenning sockets may be for example the key
3250 agreement server. Affected file lib/silcclient/client.[ch].
3251 Added functions the silc_client_add_socket and the
3252 silc_client_del_socket. They are exported to the application
3255 * Added ~./silc/clientkeys to support other client's public keys.
3257 * Renamed verify_server_key client operation to verify_public_key
3258 and added one argument to indicate the type of the connection
3259 (server, client etc.).
3261 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added silc_server_connection_auth_request to handle the
3264 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3265 silcd/packet_receive.[ch].
3267 * Added silc_server_send_connection_auth_request into the
3268 silcd/packet_send.c to send the connection auth request packet.
3270 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3273 * Fixed the public key authentication in responder side in the
3274 server. The `auth_data' pointer includes the SilcPublicKey
3275 not the path to the public key. Affected file silcd/protocol.c.
3277 * Implemented the public key authentication in the initiator side
3278 in the server. Affected file silcd/protocol.c.
3280 * Removed the [RedirectClient] config section from the server
3281 configuration. Is not needed and I don't want to implement it.
3283 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Cleaned up the CMODE command in the server. It now works
3286 correctly and supports all the modes defined in the protocol.
3287 Affected file is silcd/command.c.
3289 * Added `hmac_name' field to the SilcChannelEntry in the server
3290 to hold the default HMAC of the channel. It can be set when
3291 creating the channel (with JOIN command). Affected files
3294 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3295 type to indicate the change of the current cipher and hmac
3296 on the channel. Client can safely ignore the <cipher> argument
3297 (if it chooses to do so) since the CHANNEL_KEY packet will
3298 force the channel key change anyway. The <hmac> argument is
3299 important since the client is responsible of setting the new
3300 HMAC and the hmac key into use.
3302 * Fixed the CMODE command in the client library as well.
3304 * Tested CMODE command in router environment successfully.
3306 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Show the version of the remote client (or server) when connecting
3309 to the server. It is logged to the log file. Affected file
3310 is silcd/protocol.c.
3312 * Fixed the KILLED notify handling in the client library. The
3313 client must be removed from all channels when receiving the
3316 Also, do not remove the client entry when giving the KILL
3317 command but when the KILLED notify is received.
3319 * Removed silc_idlist_find_client_by_nickname from the server.
3320 Not needed anymore. Affected files silcd/idlist.[ch].
3322 * Implemented the CHANNEL_CHANGE notify type handling to the
3323 server. Affected file silcd/server.c.
3327 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added silc_server_send_notify_invite to send the INVITE
3330 notify between routers.
3332 * Implemented the INVITE command correctly to the server.
3334 * Implemented the INVITE notify type handling in the server.
3336 * Implemented the INVITE command to the client library and on the
3339 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Added function silc_server_get_client_resolve to find the
3342 client entry by ID from all ID lists and then resolve it
3343 (using WHOIS) if it cannot be found. Affected file is
3346 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Implemented the BAN command to the client library.
3350 * The JOIN command in the server now checks the invite list
3353 * Changed the silc_command_reply_payload_encode_va and the
3354 silc_command_payload_encode_va to support that if argument is
3355 NULL it ignores and checks the next argument. Affected file
3356 lib/silccore/silccommand.c.
3358 * Added silc_server_send_notify_ban to send the BAN notify
3359 type between routers.
3361 * Chaned the silc_notify_payload_encode to support that if
3362 argument is NULL it ignores and checks the next argument.
3363 Affected file lib/silccore/silcnotify.c.
3365 * Tested ban lists in router environment successfully.
3367 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Implemented BAN command to the server, in silcd/command.[ch].
3371 * Removed the BAN and INVITE_LIST modes from the CMODE command
3374 * Added function silc_string_match to regex match two strings.
3375 Affected files lib/silcutil/silcutil.[ch].
3377 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Redefined parts of the SilcChannelEntry in the server to support
3380 the new ban and invite lists.
3382 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3384 * Redefined the INVITE command. The same command can be used to
3385 invite individuals to the channel but also to manage the invite
3386 list of the channel (to add to and remove from the invite list).
3387 Updated the protocol specs.
3389 * Added new command SILC_COMMAND_BAN that can be used to manage
3390 the ban list of the channel. Updated the protocol specs.
3392 * Removed the channel modes: the SILC_CMODE_BAN and the
3393 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3394 in the CMODE command. The equivalent features are now available
3395 using INVITE and BAN commands. Updated the protocol specs.
3397 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3398 in the network about change in the current ban list. The notify
3399 type is not used by the client.
3401 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3402 support the invite lists.
3404 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added new function silc_string_regexify that converts string
3407 including wildcard characters into regex string that can
3408 be used by the GNU regex library. Added into the file
3409 lib/silcutil/silcutil.[ch].
3411 Added silc_string_regex_combine to combine to regex strings
3412 into one so that they can be used as one regex string by
3413 the GNU regex library. Added into the file
3414 lib/silcutil/silcutil.[ch].
3416 Added silc_string_regex_match to match two strings. It returns
3417 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3419 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Imported GNU regex to the soruce tree into lib/contrib.
3422 Fixed some compiler warning from the regex.c.
3424 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Fixed MOTD command in the server to work in router environment.
3428 * Fixed the MOTD command in the client library to support
3429 the server argument in the command.
3431 * Added `nickname_len' argument to the silc_idlist_add_client
3432 in the server, as the `nickname' argument may be binary data
3435 * Added silc_idlist_get_channels to return all channels from
3438 * Implemented LIST command to the server. Affected file is
3441 * Implemented the LIST command to the client library and on the
3444 * Added [<user count>] argument to the LIST command reply.
3445 With private channels the user count is not shown.
3447 * Updated TODO and README.
3449 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * The client entry's data.registered must be TRUE even with
3452 global client entry on global client list. The data.registered
3453 is used to check whether the client is anymore in the network,
3454 for example with WHOWAS command so it must be valid.
3456 * Fixed the WHOWAS command in the server. It now actually works
3457 in router environment. Added function into silcd/command_reply.c
3458 silc_server_command_reply_whowas_save.
3460 * Added silc_idlist_purge function to the silcd/idlist.c
3461 to periodically purge the ID Cache.
3463 * Fixed INFO command in the server. It works now in router
3464 environment. Added <server name> argument to the INFO command
3465 reply. Updated the protocol specs.
3467 * Fixed minor bug in silc_idcache_purge to not purge if the
3468 expire value is zero.
3470 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3471 they were buggy because of the WHOWAS information.
3473 * Fixed local command MSG to handle the async resolving of
3474 the remote client properly. It used to fail the first MSG.
3475 Affected file silc/local_command.c.
3477 * Added `data_len' field to SilcIDCache context.
3479 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Update TODO. Todo in commands in the server.
3483 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3486 used by routers as broadcast packet to inform other routers
3487 about the changed user mode.
3489 Implemented the notify handling in the server. Affected file is
3490 silcd/packet_receive.c. Added the function
3491 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3493 * Added new generic Channel Payload and deprecated the New Channel
3494 Payload. The New Channel Payload is now the generic Channel
3497 * Added new argument `mode' to the silc_server_send_new_channel
3498 as it is required in the Channel Payload now.
3500 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3501 and created a new and real SilChannelPayload to represent the
3502 new generic Channel Payload. Implemented the encode/decode
3503 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3505 * Added silc_server_get_client_channel_list to return the list
3506 of channels the client has joined for WHOIS command reply.
3507 Affected file silcd/server.[ch].
3509 * Implemented the channel list sending in the WHOIS command reply
3510 in server and in the client.
3512 Implemented the channel list displaying on the user interface
3513 as well. Affected file silc/client_ops.c.
3515 * Added silc_channel_payload_parse_list to parse list of Channel
3516 Payloads. It returns SilcDList list of SilcChannelPayloads.
3517 Client for example can use this function to parse the list of
3518 channels it receives in the WHOIS command reply. The caller
3519 must free the list by calling silc_channel_payload_list_free.
3520 Affected files lib/silccore/silcchannel.[ch].
3522 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added one new argument <user mode> to the WHOIS command reply
3525 to return the mode of the user in SILC. Updated the protocol
3528 Implemented it to the server and client.
3530 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Fixed the mode printing on the user interface on joining.
3533 Affected file silc/client_ops.c.
3535 * Implemented the UMODE command and user modes in general to the
3536 client library and to the user interface.
3538 * Implemented the UMODE command to the server.
3540 * The server now sends UNKNOWN_COMMAND error status if client sends
3541 unknown command. Affected file silcd/command.c.
3543 * All server commands now handle the command identifier the right
3544 way when sending the command reply to the client. The client can
3545 use to identify the command replies with the identifier.
3547 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Added silc_server_get_client_route to resolve the route to
3550 the client indicated by the client ID. Affected file is
3553 * Added silc_server_relay_packet as general function to relay
3554 packet to arbitrary destination. This deprecates functions
3555 like _send_private_message_key, _relay_notify etc. Affected
3556 file is silcd/packet_send.[ch].
3558 Removed silc_server_send_key_agreement,
3559 silc_server_send_private_message_key and
3560 silc_server_packet_relay_notify functions from the file
3561 silcd/packet_send.[ch].
3565 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3566 server. Affected file silcd/packet_receive.[ch].
3568 * Implemented the KILL command to the client. Implemented the
3569 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3570 Affected files lib/silcclient/command[_reply].c and
3571 lib/silcclient/client_notify.c. Implemented the KILL notify
3572 printing in the user inteface.
3574 * Fixed a lot silc_parse_nick memory leaks from the client
3575 library in the file lib/silcclient/command.c.
3577 * Changed the silc_server_send_notify_on_channels's `sender'
3578 argument from SilcSocketConnection to SilcClientEntry to
3579 check the sender as entry and not as connection object and not
3580 to send to the client provided as argument. The affected file
3581 is silcd/packet_send.[ch].
3583 * The notify packets that are destined directly to the client used
3584 to not to be processed by the server. Now changed that and the
3585 server processes all notify packets. After relaying the packet
3586 to the client the notify packet is processed in the server.
3588 * The silc_server_free_client_data now checks whether there is
3589 pending outgoing traffic for the client and purges the data to
3590 the network before removing the client entry.
3592 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3595 an client is killed from the SILC Network. Updated the protocol
3598 Added new function silc_server_send_notify_killed to the
3599 silcd/packet_send.[ch].
3601 * Added function silc_server_packet_relay_notify to relay notify
3602 packets that are destined directly to a client. In this case
3603 the server does not process the notify packets but merely relays
3604 it to the client. Affected file silcd/packet_send.[ch].
3606 Added also silc_server_packet_process_relay_notify to check
3607 whereto relay the notify. Affected file is
3608 silcd/packet_receive.[ch].
3610 * Implemented the KILL command to the server.
3614 * Added the backup schema desgined last fall to the protocol
3615 specs for everyone to see. The specification is in the
3616 *-spec-xx.txt draft and the packet type definitions for the
3617 backup routers is in *-pp-xx.txt draft. Thusly, added also
3618 new packet type SILC_PACKET_CELL_ROUTERS.
3620 * A big security problem in the implementation discovered. The
3621 signoff of an client did not cause new channel key generation
3622 which it of course should've done. The channel keys must be
3623 always re-generated when client leaves (or signoffs) the channel.
3624 The silc_server_remove_from_channels funtion now handles
3625 the channel key re-generation.
3627 * Added `sender' argument to the silc_server_send_notify_on_channels
3628 to not to send the client provided as argument. Affected file
3629 silcd/packet_send.[ch].
3631 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Implemented OPER and SILCOPER commands into the server and
3636 * Added silc_auth_verify and silc_auth_verify_data to verify
3637 the authentication directly from the authentication payload.
3638 It supports verifying both passphrase and public key based
3639 authentication. Affected file lib/silccore/silcauth.[ch].
3641 * Added `hash' field to the SilcIDListData structure. It is the
3642 hash negotiated in the SKE protocol. Affected file is
3645 * Slight redesigning of the SilcAuthPayload handling routines.
3646 Do not send SilcPKCS but SilcPublicKey as argument.
3648 * Implemented the public key authentication support to the
3649 serverconfig. The public key is loaded from the provided path
3650 and saved as authentication data to void * pointer. Thus,
3651 changed the unsigned char *auth_data to void *auth_data;
3653 * Fixed SHUTDOWN command to send the reply before the server
3654 is shutdown. :) Affected file silcd/command.c.
3656 * Fixed fatal bug in CONNECT command. The hostname was invalid
3657 memory and server crashed. Affected file silcd/command.c.
3659 * Fixed fatal bug in CLOSE command. The server_entry became
3660 invalid but was referenced later in the command. Affected file
3663 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Fixed fatal bug in failure packet handling. Server ignored
3666 the failure and thus crashed when it came.
3670 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3673 that the command may be executed only once in (about) 2 seconds.
3674 The old SILC_CF_LAG flag is same but allows command bursts up
3675 to five before limiting.
3677 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3678 server code. Various commands now includes the CF_LAG_STRICT
3679 flag to disallow any kind of miss-use of the command.
3681 * Fixed the silc_buffer_unformat to not to allocate any data
3682 if the length of the data is zero. It used to allocate the
3683 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3685 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Changed the format of AdminConnection configuration section
3688 in the server. Added username of the admin to the format.
3689 Affected files silcd/serverconfig.[ch].
3691 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3692 to return admin configuration data by host, username and/or
3695 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Implemented WHOWAS command to the server. Added the functions:
3699 silc_server_command_whowas_parse,
3700 silc_server_command_whowas_send_reply,
3701 silc_server_command_whowas_from_client and
3702 silc_server_command_whowas_from_server
3704 * Added <Client ID> argument to the WHOWAS command reply. Updated
3705 the protocol specs accordingly.
3707 * Implemented WHOWAS command and command_reply to the client
3710 Implemented the WHOWAS printing on the user interface.
3712 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Added new argument to the WHOWAS command reply, the real name.
3715 It is an optional argument. Updated the protocol specs.
3717 * Added SilcIDCacheDestructor callback that is registered when
3718 the SilcIDCache is allocated. The callback is called when
3719 an cache entry in the ID Cache expires, or is purged from the
3720 cache. Added into lib/silccore/idcache.[ch].
3722 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3723 to destruct the client entries when the cache entry expires.
3724 Other ID Cache's in server and in the client library ignores
3727 * If the ID Cache entry's `expire' field is zero then the entry
3728 never expires. Added boolean `expire' argument to the
3729 silc_idcache_add function in the lib/silccore/idcache.[ch].
3730 If it is TRUE the default expiry value is used.
3732 * Added silc_server_free_client_data_timeout that is registered
3733 when client disconnects. By default for 5 minutes we preserve
3734 the client entry for history - for WHOWAS command.
3736 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Added support to the server to enforce that commands are not
3739 executed more than once in 2 seconds. If server receives
3740 commands from client more frequently, timeout is registered
3741 to process the commands. Affected file silcd/command.c.
3742 Added new function silc_server_command_process_timeout.
3744 * Changed NICK_NOTIFY handling in client library to check that
3745 if the client's nickname was changed, so there is no need to
3746 resolve anything from the server.
3748 * Removed error printing from the WHOIS and IDENTIFY commands.
3749 If error occurs then it is ignored silently in the client library.
3750 The application, however, may map the received error to
3751 human readable error string. The application currently maps
3752 the NO_SUCH_NICKNAME error to string.
3754 * Made the command status message public to the application. Moved
3755 them from lib/silcclient/command_reply.c to
3756 lib/silcclient/command_reply.h. The application can map the
3757 received command status to the string with the
3758 silc_client_command_status_message function.
3760 * Added check to the server to check that client's ID is same
3761 as the Source ID in the packet the client sent. They must
3764 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added dist-bzip hook to the Makefile.am to make bzip2
3767 compressed distributions.
3769 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Server now enforces the maximum length for the nickname and
3772 the channel as protocol specification dictates. 128 bytes for
3773 nickname and 256 bytes for channel name.
3775 * Moved the WHOIS printing to the application. The client libary
3776 does not print out the WHOIS information anymore, the application
3777 must do it. Renamed silc_client_command_reply_whois_print to
3778 the silc_client_command_reply_whois_save.
3780 The client's idle time is also sent to the application now, and
3781 the idle is shown on screen.
3783 * Added silc_client_command_reply_identify_save to save the
3784 received IDENTIFY entries.
3786 * Do not check for channel private keys in message sending and
3787 reception if the channel does not have the PRIVKEY mode set.
3788 Affected file lib/silclient/client_channel.c.
3790 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3793 just surfaced after chaning the JOIN procedure.
3795 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Added silc_client_get_clients_by_list to get client entries
3798 from Client ID list, that is returned for example by JOIN
3799 and USERS command replies. The application should use this
3800 function for example when JOIN command reply is received to
3801 resolve the clients already on the channel (library does not
3802 do that anymore as USERS command reply is not used in the JOIN
3803 procedure anymore). Affected files lib/silcclient/silcapi.h and
3804 lib/silcclient/idlist.c.
3806 * JOIN command reply and USERS command reply returns now SilcBuffer
3807 pointers instead of unsigned char pointers when returning
3808 the client list and mode list.
3810 * Added <Client ID> argument to the JOIN command reply, mainly
3811 for the server to identify for which client the command was
3812 originally sent. Updated protocol specs accordingly.
3814 * Added SilcDlist private_key pointer to the SilcChannelEntry
3815 in the client to support the channel private keys. Affected
3816 file is lib/silcclient/idlist.h.
3818 * Added SilcChannelPrivateKey argument to the function
3819 silc_client_send_channel_message so that application can choose
3820 to use specific private ke if it wants to. If it is not provided,
3821 the normal channel key is used, unless private keys are set.
3822 In this case the first (key that was added first) is used
3823 as the encryption key.
3825 * Implemented the support for channel private key handling.
3826 Implemented the following functions:
3828 silc_client_add_channel_private_key,
3829 silc_client_del_channel_private_keys,
3830 silc_client_del_channel_private_key,
3831 silc_client_list_channel_private_keys and
3832 silc_client_free_channel_private_keys
3834 Affected file lib/silcclient/client_channel.c.
3836 * Added the support for the private keys in the channel message
3837 sending and encryption and in the message reception and
3838 decryption. Affected funtions are
3839 silc_client_send_channel_message and silc_client_channel_message.
3841 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added SKE's key verify callback to the client library's
3844 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3846 * Removed the statement that server (or router) must send USERS
3847 command reply when joining to the channel so that the client
3848 knows who are on the channel. Instead, the client list and
3849 client's mode list is now sent in the JOIN command reply to the
3850 client who joined channel. This is better solution.
3852 * Added function silc_server_get_users_on_channel and function
3853 silc_server_save_users_on_channel to the silcd/server.[ch].
3855 * Removed function silc_server_command_send_users from the
3858 * Do not show topic on the client library anymore. The topic is
3859 sent in the command reply notify to the application and the
3860 application must show the topic now.
3862 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added client searching by nickname hash into the IDENTIFY and
3865 WHOIS commands in the server as they were clearly missing from
3866 them. Affected file is silcd/command.c.
3868 * Fixed a bug in private message receiving in the client library.
3869 The remote ID was freed and it wasn't supposed, now it is
3872 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Minor fix to the channel payload; allocate the data area, as it
3875 needs to be of specific length.
3877 * If the key agreement port is zero then the operating
3878 system will define the bound port. Affected files are
3879 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3881 * Added new function silc_channel_payload_decrypt into the file
3882 lib/silccore/silcchannel.[ch].
3884 * Moved the channel message etc, check from silc_packet_decrypt
3885 to applications. The library calls now a generic
3886 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3887 when the packet is either normal or special. This was done to
3888 allow more wide range of checking that was not allowed when
3889 the code was in library. Now applications can do virtually any
3890 checks to the packet and return to the library the decision how
3891 the packet should be processed. Affected files are
3892 lib/silccore/silcpacket.[ch].
3894 Added silc_server_packet_decrypt_check to the server and
3895 silc_client_packet_decrypt_check to the client library.
3897 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3898 to send with specified source and destination information.
3900 * Channel message delivery between routers was broken after the
3901 channel key distribution was fixed earlier. The channel key
3902 was used be to distributed to other routers as well which is not
3903 allowed by the protocol. Now this is fixed and channel keys
3904 really are cell specific and the channel message delivery between
3905 routers comply with the protocol specification.
3907 * Fixed various commands in server to check also the global list
3908 for the channel entry and not just the local list. The affected
3909 file silcd/command.c.
3911 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Added assert()s to buffer formatting and unformatting routines
3914 to assert (if --enable-debug) when error occurs. Affected
3915 file: lib/silcutil/silcbuffmt.c.
3917 * Changed to auto-reconnect to check whether the remote host is
3918 router and register the re-connect timeout if it is. It used
3919 to check that whether we are normal server, but router must do
3920 auto-reconnect with another router as well. Affected file
3923 * Removed the [<key len>] option from CMODE command as the cipher
3924 name decides the key length, nowadays. See the defined ciphers
3925 from the protocol specification.
3927 * Added [<hmac>] option to the CMODE command to define the HMAC
3928 for the channel. Added SILC_CMODE_HMAC channel mode.
3930 * Added [<hmac>] option for the JOIN command so that user can
3931 select which HMAC is used to compute the MACs of the channel
3934 * Added Hmac field to the Channel Message Payload. The integrity
3935 of plaintext channel messages are now protected by computing
3936 MAC of the message and attaching the MAC to the payload. The
3937 MAC is encrypted. Now, it is clear that this causes some
3938 overhead to the size of the packet but rationale for this is that
3939 now the receiver can verify whether the channel message decrypted
3940 correctly and also when private keys are set for the channel the
3941 receiver can decrypt the packet with several keys and check from
3942 the MAC which key decrypted the message correctly.
3944 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3945 lib/silccrypt/silccipher.[ch].
3947 * Added silc_hash_len to return the digest length into the
3948 lib/silcrypt/silchash.[ch].
3950 * Rewrote parts of Silc Channel Payload interface in the
3951 lib/silccore/silcchannel.[ch]. The encode function now also
3952 encrypts the packet and parse function decrypts it.
3954 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Fixed a minor formatting bug in the SKE's key material processing.
3957 It actually might have processed the keys wrong way resulting
3960 * Redefined the mandatory HMAC algorithms and added new algorithms.
3961 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3962 and hmac-md5 truncated to 96 bits. The mandatory is now
3963 hmac-sha1-96. Rest are optional (including the one that used
3964 to be mandatory). Rationale for this is that the truncated HMAC
3965 length is sufficient from security point of view and can actually
3966 make the attack against the HMAC harder. Also, the truncated
3967 HMAC causes less overhead to the packets. See the RFC2104 for
3970 * Added new [hmac] configuration section. The SKE used to use
3971 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3972 is of course wrong. The official names that must be proposed in
3973 the SKE are the ones defined in the protocol specification
3974 (hmac-sha1-96 for example). The user can configure any hmac
3975 using any hash function configured in the [hash] section. At
3976 least, the mandatory must be configured.
3978 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3980 * Added HMAC list to the SKE proposal list. It has now both
3981 hash algorithm list and HMAC list. This makes the protocol
3982 incompatible with previous versions. The SKE now seems to work
3983 the way it is supposed to work, for the first time actually.
3985 * Defined plain Hash algorithms to the protocol specification.
3988 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Implemented support for key agreement packets into the server.
3991 Added functions silc_server_key_agreement and
3992 silc_server_send_key_agreement. Other than these functions,
3993 server has nothing to do with this packet.
3995 * Added support for private message key packets into the server.
3996 Added functions silc_server_private_message_key and
3997 silc_server_send_private_message_key.
4001 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4002 called in the protocol's final callback instead in the END
4003 protocol state. This makes a little more sense and in the same
4004 time in client we can use the same protocol routines for normal
4005 key exchange and to key agreement packet handling as well.
4007 * Added to both client's and server's KE protocol context the
4008 SilcSKEKeyMaterial pointer to save the key material. We will
4009 bring the key material to the protocol's final callback by doing
4010 this. The final callback must free the key material.
4012 * Added SKE's packet_send callback into client's KE protocol
4013 context so that the caller can choose what packet sending function
4014 is used. This way we can use different packet sending when
4015 doing normal SKE when doing key agreement packet handling (in
4016 the key agreement packet handling we do not want to encrypt
4019 * Implemented the responder side of the key agreement routines
4020 in the client. The client can now bind to specified port and
4021 accept incoming key negotiation. The key material is passed
4022 to the application after the protocol is over.
4024 * Implemented the processing of incoming Key Agreement packet
4025 in the client. Added function silc_client_key_agreement to
4028 * Implemented the intiator side of the key agreement routines
4029 in the client. The client can now initiate key agreement with
4030 another remote client. The key material is passed to the
4031 application after the protocol is over.
4033 * Created client_keyagr.c to include all the key agreement
4036 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4037 SILC_TASK_CALLBACK except that it is not static.
4039 * Created client_notify.c and moved the Notify packet handling
4040 from the client.[ch] into that file.
4042 * Created client_prvmsg.c and moved all private message and
4043 private message key routines from the client.[ch] into that file.
4045 * Create client_channel.c and moved all channel message and
4046 channel private key routines from the client.[ch] into that file.
4048 * Changed silc_client_get_client_by_id_resolve to resolve with
4049 WHOIS command instead of IDENTIFY command, in the file
4050 lib/silclient/idlist.c.
4052 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Implemented the SKE's responder side to the Client library.
4056 * When FAILURE is received to the protocol do not trust it
4057 blindly. Register a timeout to wait whether the remote closes
4058 the connection as it should do it, only after that process the
4059 actual failure. This was changed to both client and server.
4061 * Added client_internal.h to include some of the structures
4062 there instead of client.h in lib/silcclient/.
4064 * Added function silc_task_unregister_by_callback to unregister
4065 timeouts by the callback function.
4067 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Some "Incomplete WHOIS info" errors has been appearing on the
4070 log files. Took away the entry->userinfo check from WHOIS
4071 reply sending. The entry->userinfo is now " " if client did not
4072 provide one. I thought this was fixed earlier but something
4073 is wrong still. Let's see if the error still appears.
4075 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Fixed a minor bug in the login when the channel key is
4078 re-generated in the server. It used to generate the key in
4079 wrong order and thus caused problems in the channel traffic.
4081 * Fixed a minor bug in channel key distsribution after
4082 KICK command. The key was not sent to the router even though
4085 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Added silc_ske_process_key_material_data as generic routine
4088 to process any key material as the SILC protocol dictates. The
4089 function is used by the actual SKE library but can be used by
4090 applications as well. This relates to the private message keys
4091 and the channel private keys since they must be processed the
4092 same way the normal SILC session keys. The protocol dictates
4093 this. Affected files: lib/silcske/silcske.[ch].
4095 Added also silc_ske_free_key_material to free the
4096 SilcSKEKeyMaterial structure.
4098 * Defined silc_cipher_set_key function to set the key for
4099 cipher without using the object's method function. The affected
4100 files: lib/silccrypt/silccipher.[ch].
4102 * Implemented silc silc_client_add_private_message_key,
4103 silc_client_add_private_message_key_ske,
4104 silc_client_del_private_message_key,
4105 silc_client_list_private_message_keys and
4106 silc_client_free_private_message_keys functions in the
4109 Added functions silc_client_send_private_message_key to send
4110 the Private Message Key payload and silc_client_private_message_key
4111 to handle incoming Private Message Key payload.
4113 * Added Cipher field to the Private Message Key payload to set
4114 the cipher to be used. If ignored, the default cipher defined
4115 in the SILC protocol (aes-256-cbc) is used.
4117 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Removed lib/silcclient/ops.h file.
4121 Redefined parts of the SILC Client Library API. Created new
4122 file silcapi.h that deprecates the ops.h file and defines the
4123 published Client Library API. Defined also private message key
4124 API and channel private key API into the file.
4126 This is the file that the application must include from the
4127 SILC Client Library. Other files need not be included by
4128 the application anymore.
4130 * Added new key_agreement client operation callback and also
4131 defined the Key Agreement library API for the application.
4133 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4136 is used by clients to request key negotiation between another
4137 client in the SILC network. If the negotiation is started it
4138 is performed using the SKE protocol. The result of the
4139 negotiation, the secret key material, can be used for example
4140 as private message key.
4142 Implemented the Key Agreement payload into the files
4143 lib/silccore/silauth.[ch].
4145 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Redefined ciphers for the SILC protocol. Added some new ciphers
4148 and defined the key lengths for the algorithms. Changed the
4149 code accordingly. The default key length is now 256 bits.
4151 * Fixed SKE key distribution function silc_ske_process_key_material
4152 when the key length is more than 128 bits. The default key
4153 length in SILC is now 256 bits.
4155 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4156 to indicate unsupported algorithm.
4158 * Renamed rijndael.c to aes.c and all functions as well.
4160 * Fixed a long standing channel key setting bug in client library.
4161 Weird that it has never surfaced before.
4163 * Fixed bug in channel deletion. If the entire channel is removed
4164 then it must also delete the references of the channel entry
4165 from the client's channel list as the client's channel entry and
4166 the channel's client entry share same memory.
4168 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Implemented CONNECT and SHUTDOWN commands in the client.
4172 * Implemented CLOSE command to the client.
4174 * Added the function silc_idlist_find_server_by_name into the
4175 files silcd/idlist.[ch].
4177 Added the function silc_idlist_find_server_by_conn into the
4178 files silcd/idlist.[ch].
4180 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * DIE command was renamed to SHUTDOWN. Updated the both code
4185 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4186 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4188 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4191 * Added function silc_server_create_connection function to create
4192 connection to remote router. My server implementation actually
4193 does not allow router to connect to normal server (it expects
4194 that normal server always initiates the connection to the router)
4195 so the CONNECT command is only good for connecting to another
4198 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4201 or some other client was kicked from the channel.
4203 Implemented the handling of the notify type to both client
4206 Implemented silc_server_send_notify_kicked to send the KICKED
4207 notify. It is used to send it to the server's primary router.
4209 * Implemented the KICK command into server and client.
4211 * Added `query' argument to the silc_idlist_get_client function
4212 to indicate whether to query the client from server or not if
4215 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4216 to indicate that the client is not channel founder.
4220 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Removed the rng context from SilcPacketContext structure and
4223 changed that the packet routine uses the Global RNG API.
4225 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added support for quit message that client can "leave" on the
4228 channel when it quits the SILC. It is ditributed inside the
4229 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4231 Added silc_server_free_client_data that will take the
4232 signoff message as argument.
4234 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4236 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Updated parts of the protocol specification to keep it up
4241 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4244 payloads in one packet.
4246 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4247 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4248 use now the new List flag.
4250 * Also deprecated the following packet types: REPLACE_ID,
4251 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4253 * Added list support for Notify packet in server.
4255 * Added silc_server_send_notify_channel_change to send the
4256 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4257 the silc_server_send_replace_id.
4259 * Added silc_server_send_notify_nick_change to send the
4260 NICK_CHANGE notify type. Deprecates the function
4261 silc_server_send_replace_id.
4263 * Added silc_server_send_notify_join to send the JOIN notify type.
4264 Deprecates the function silc_server_send_new_channel_user.
4266 * Added silc_server_send_notify_leave to send LEAVE notify type.
4267 Deprecates the function silc_server_send_remove_channel_user.
4269 * Added silc_server_send_notify_cmode and
4270 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4271 types. Deprecates the silc_server_send_set_mode function.
4273 * Added SERVER_SIGNOFF notify type to indicate that server has
4274 quit. This means that all clients on the channel from that
4275 server will drop. This can be also used when netsplit happens.
4277 Deprecated REMOVE_ID packet type since it is not needed anymore
4280 Added silc_server_send_notify_server_signoff to send the
4281 SERVER_SIGNOFF notify type. Deprecates the function
4282 silc_server_send_remove_id.
4284 Added also silc_server_send_notify_signoff to send the
4285 SIGNOFF notify type.
4287 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4288 SILC protocol from this day on. Changed the protocol
4289 specification as well.
4291 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4292 notify type. It is used between routers to notify about
4293 topic changes on a channel.
4295 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4298 * Partly updated the protocol specification to comply with the
4299 changes now made. It is still though a bit outdated.
4301 * The JOIN notify type now takes one extra argument <Channel ID>.
4302 The packet used to be destined to the channel but now the
4303 JOIN type may be sent as list thus it is impossible to
4304 destine it to any specific channel. By adding this argument
4305 it is again possible.
4307 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added CREDITS file. The CHANGES and CREDITS file will appear
4310 in the distribution as well.
4312 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4315 types in the server's silcd/packet_receive.c.
4317 * Implemented CMODE and CUMODE to work in router environment.
4319 * Fixed minor encoding and decoding buglet from the
4320 lib/silccore/silcmode.c.
4322 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4325 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4327 * Changed all SilcConfigServer* and silc_config_server* to
4328 SilcServerConfig* and silc_server_config*, respectively.
4331 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Associated the ID (client or server ID) to the Authentication
4334 Payload to avoid any possibility of forging. Updated the
4335 protocol specification and the code accordingly.
4337 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * The RSA key length is now save to the RsaKey context in the
4340 key generation process in lib/silccrypt/rsa.c. The key length
4341 is now used to figure out the maximum size of the block allowed
4342 to be encrypted/signed.
4344 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4345 is equivalent to the silc_mp_mp2bin but does not allocate any
4348 * Changed silc_mp_mp2bin API to take length argument. If it is
4349 non-zero then the buffer is allocated that large. If zero, then
4350 the size is approximated using silc_mp_sizeinbase, which however
4353 * Created Global RNG API which is global RNG that application can
4354 initialize. After initializing, any routine anywhere in the
4355 code (including library) can use RNG without allocating a new
4356 RNG object. This was done to allow this sort of use of the
4357 RNG in code that has no chance to allocate RNG object. All
4358 applications currently allocate this and many routines in the
4359 library use this. Affected file lib/silccrypt/silcrng.[ch].
4361 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4362 it to use the Global RNG API.
4364 * Defined Authentication Payload into protocol specification that
4365 is used during SILC session to authenticate entities. It is
4366 used for example by client to authenticate itself to the server
4367 to obtain server operator privileges.
4369 Implemented this payload into the lib/silccore/silcauth.[ch].
4370 Implemented also routines for public key based authentication
4371 as the new protocol specification dictates.
4373 Moved definitions of different authentication methods from
4374 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4376 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4377 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4378 silc_pkcs_verify_with_hash functions into the file
4379 lib/silccrypt/silcpkcs.[ch].
4381 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * The client entry's userinfo pointer must be always valid.
4384 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4385 will fail since it requires the userinfo. Now, the userinfo
4386 is allocated as "" if actual userinfo does not exist. Actually,
4387 it must exist and it is totally Ok to drop client connections
4388 that does not announce the userinfo. However, we will make
4389 this workaround for now.
4391 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4392 to return the remote port by socket.
4394 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4397 SILC_SERVER_PENDING_EXEC and added an new macro
4398 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4399 data or when error occurs while processing the pending command.
4401 Added new argument `destructor' into silc_server_command_pending
4402 and to the SilcServerCommandPending object. This destructor is
4403 now called after calling the pending callback or if error occurs
4404 immediately. If error occurs the actual pending callback won't
4405 be called at all - only the destructor. The destructor may be
4406 NULL if destructor is not needed.
4408 All this applies for client library code as well. Similar
4409 changes were made there as well for the pending commands.
4411 In the client, the application must now allocate the
4412 SilcClientCommandContext with the silc_client_command_alloc
4415 * Added reference counter to the SilcServerCommandContext. Added
4416 function silc_server_command_alloc and silc_server_command_dup
4419 Same type of functions added to the client library for the same
4422 * Removed the cmd_ident from IDListData away since it is now
4423 global for all connections. It is the command identifier used
4424 in command sending and with pending commands. The affected file
4427 * Added reference counter to the SilcSocketConnection objecet to
4428 indicate the usage count of the object. The object won't be
4429 freed untill the reference counter hits zero. Currently only
4430 server uses this, and client ignores it. The client must be
4431 set to use this too later. The affected files are
4432 lib/silccore/silcsockconn.[ch]. Added also the function
4433 silc_socket_dup to increase the reference counter.
4435 This was mainly added because it is possible that the socket
4436 is removed underneath of pending command or other async
4437 operation. Now it won't be free'd and proper DISCONNECTING
4438 flags, etc. can be set to avoid sending data to connection that
4439 is not valid anymore.
4441 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4442 the connection. After that it sets SILC_SET_DISCONNECTED.
4443 It is, however, possible that the socket data is not still freed.
4444 The silc_server_packet_process now checks that data is not
4445 read or written to connection that is DISCONNECTED. The socket
4446 get's freed when the reference counter hits zero.
4448 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Changed the client operation API: channel_message operation's
4451 `sender' is now the client entry of the sender, not the nickname
4452 and the `channel' is the channel entry, not the channel name.
4454 In the private_message operation the `sender' is now also the
4455 client entry of the sender not the nickname.
4457 Affected file is lib/silcclient/ops.h and all applications
4458 using the client operations.
4460 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Moved the calling of ops->connect() from connect_to_server_final
4463 into receive_new_id functin since that is the point when the
4464 client is actually allowed to send traffic to network. The
4465 affected file is lib/silcclient/client.c.
4467 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4470 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4471 (if needs broadcasting) instead of broadcasting the packets one
4472 by one which would make a burst in the network traffic.
4474 * Added `broadcast' argument to the functions in silcd/server.[ch]
4475 silc_server_create_new_channel[_with_id] to indicate whether
4476 to send New Channel packet to primary router.
4478 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * Added new function into the silcd/server.[ch] files:
4481 silc_server_create_new_channel_with_id to create new channel with
4482 already existing Channel ID.
4484 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4485 lib/silccore/silcpacket.h. This packet is used t send list of
4486 Set Mode payloads inside one packet. Server uses this to set
4487 the modes for the channels and clients on those channels, that it
4488 announced to the router when it connected to it. The protocol
4489 specification has been updated accordingly.
4491 * The silc_server_new_channel did not handle the packet coming
4492 from normal server as it normally does not send that. However,
4493 when it announces its channels it does send it. Implemented
4494 the support for that.
4496 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4497 into the file lib/silccore/id.h.
4499 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed memory leaks in the functions silc_idlist_del_client,
4502 silc_idlist_del_channel and silc_idlist_del_server in the file
4503 silcd/idlist.c. All of those leaked like a sieve.
4505 * Fixed some small memory leaks in the client's function
4506 silc_client_notify_by_server.
4508 * Added functions into silcd/server.c: silc_server_announce_clients,
4509 silc_server_announce_channels and silc_server_announce_server.
4510 These functions are used by normal and router server to announce
4511 to its primary router about clients, channels and servers (when
4512 router) that we own. This is done after we've connected to the
4515 These functions effectively implements the following packet types:
4516 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4517 and SILC_PACKET_NEW_ID_LIST.
4519 * Added new functions into the silcd/packet_receive.[ch]:
4520 silc_server_new_id_list, silc_server_new_channel_list and
4521 silc_server_new_channel_user_list to handle the incoming
4522 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4524 * Added support of changing Channel ID in the function
4525 silc_server_replace_id. If the server that announces a channel
4526 to the router already exists in the router (with same name but
4527 with different Channel ID), router is responsible to send
4528 Replace ID packet to the server and force the server to change
4529 the Channel ID to the one router has.
4531 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4532 client that the Channel ID has been changed by the router. The
4533 normal server sends this to the client. Client must start using
4534 the new Channel ID as the channel's ID.
4536 Implemented handling of this new type into lib/silcclient/client.c
4537 into the function silc_client_notify_by_server.
4539 * Added new function silc_idlist_replace_channel_id into the files
4540 silcd/idlist.[ch] to replace the Channel ID.
4542 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Call silc_server_command_identify_check always when processing
4545 the IDENTIFY command in silcd/command.c
4547 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4550 send keepalive packets. The packet can be sent by clients,
4551 servers and routers.
4553 Added function silc_socket_set_heartbeat into the file
4554 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4555 If not set, the heartbeat is not performed. The actual
4556 heartbeat is implemented in the low level socket connection
4557 library. However, application is responsible of actually
4560 Added silc_server_send_heartbeat to send the actual heartbeat
4561 packet into silcd/packet_send.[ch]. Server now performs
4562 keepalive with all connections.
4564 * Added silc_task_get_first function into lib/silcutil/silctask.c
4565 to return the timeout task with shortest timeout. There was a bug
4566 in task unregistration that caused problems. TODO has been
4567 updated to include that task system must be rewritten.
4569 * The client library will now resolve the client information when
4570 receiving JOIN notify from server for client that we know but
4571 have incomplete information.
4573 * Rewrote parts of silc_server_remove_from_channels and
4574 silc_server_remove_from_one_channel as they did not remove the
4575 channel in some circumstances even though they should've.
4577 * Encryption problem encountered in server:
4579 The LEAVE command used to send the Channel Key packet to the
4580 router immediately after generating it. However, the code
4581 had earlier sent Remove Channel user packet but not immediately,
4582 ie. it was put to queue. The order of packets in the router
4583 was that Channel Key packet was first and Remove Channel User
4584 packet was second, even though they were encrypted in the
4585 reverse order. For this reason, MAC check failed. Now, this
4586 is fixed by not sending the Channel Key packet immediately but
4587 putting it to queue. However, this is more fundamental problem:
4588 packets that are in queue should actually not be encrypted
4589 because packets that are sent immediately gets encrypted
4590 actually with wrong IV (and thus MAC check fails). So, packets
4591 that are in queue should be encrypted when they are sent to
4592 the wire and not when they put to the queue.
4594 However, the problem is that the current system has not been
4595 designed to work that way. Instead, the packet is encrypted
4596 as soon as possible and left to the queue. The queue is then
4597 just purged into wire. There won't be any fixes for this
4598 any time soon. So, the current semantic for packet sending
4601 o If you send packet to remote host and do not force the send
4602 (the packet will be in queue) then all subsequent packets to the
4603 same remote host must also be put to the queue. Only after the
4604 queue has been purged is it safe again to force the packet
4607 o If you send all packets immediately then it safe to send
4608 any of subsequent packets through the queue, however, after
4609 the first packet is put to queue then any subsequent packets
4610 must also be put to the queue.
4612 Follow these rules and everything works fine.
4614 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Added new function silc_server_remove_clients_by_server to
4617 remove all client entries from ID list when the server connection
4618 is lost. In this case it is also important to invalidate all
4619 client entires as they hold the invalid server entry. This
4620 fixes fatal bug when server has lost connection and will reconnect
4623 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Made some sanity checks to silc_server_daemonise like to check
4626 whether the requested user and group actually exists.
4628 * Added sanity check to SKE's silc_ske_responder_finish to check
4629 that the public and private key actually is valid.
4631 * Invalidate the client's nickname when receiving Replace ID
4632 packet and the Client ID is being replaced. This means that the
4633 server will query the nickname if someone needs it (client)
4636 * Sort the ID Cache in client library when the ID Cache data
4637 has changed (needs sorting).
4639 * Do not allow for SILC client to create several connections to
4640 several servers. The client does not support windows right now
4641 and generating multiple connections causes weird behaviour.
4643 Irssi-silc client does support windows and can handle several
4644 connections without problems, see: www.irssi.org and SILC plugin.
4646 * Fixed some places where client was added to the IDList. The
4647 rule of thumb is following (in order to get everything right):
4648 If the client is directly connected local client then the
4649 `connection' argument must be set and `router' argument must be
4650 NULL to silc_idlist_add_client function. If the client is not
4651 directly connected client then the `router' argument must
4652 bet set and the `connection' argument must be NULL to the
4653 silc_idlist_add_client function.
4655 * The funtion silc_server_packet_send_local_channel actually did
4656 not check whether the client was locally connected or not. It
4657 does that now. Fixed a bug related to LEAVE command.
4659 * Fixed Remove Channel User payload parsing bug in server's
4660 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4662 * The server's silc_server_save_channel_key now checks also the
4663 global ID list for the channel as it might not be in the local
4664 list. Fixed a bug related to LEAVE command.
4666 * Is this the end of the [<unknown>] buglet that has been lurking
4667 around for a long time? A little for loop fix in server's
4668 silc_server_command_whois_parse that is used by both IDENTIFY
4669 and WHOIS command. At least, this was a clear bug and a cause
4670 of one type of [<unknown>] buglet.
4672 * WHOIS and IDENTIFY commands call the function
4673 silc_server_command_[whois/identify]_check function even if
4674 we are not router server.
4676 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Added --with-gmp configuration option. If set the GMP
4679 is always compiled in the SILC source tree. If not set then
4680 it is checked whether the system has the GMP3 installed. If
4681 it has then the GMP won't be compiled (the system's headers
4682 and library is used), if it doesn't have it then the GMP is
4683 compiled in the SILC source tree.
4685 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Changed RSA private exponent generation to what PKCS #1
4688 suggests. We try to find the smallest possible d by doing
4689 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4690 not security fix but optimization.
4692 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * Added new config entry [Identity] to fork the server and run
4695 it as specific user and group. A patch from Bostik.
4697 * Imported Dotconf configuration library into lib/dotconf.
4698 This will be used to create the SILC configuration files later.
4699 It will appear in the distsribution after this commit.
4701 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * A big code auditing weekend happening. Auditing code for
4704 obvious mistakes, bugs and errors. Also, removing any code
4707 Removed files for being obsolete:
4709 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4710 inline in the file lib/silcutil/silcbuffer.h)
4712 o lib/silcutil/silcbufutil.c (the header has inline versions)
4714 Changed code to fix possible error conditions:
4716 o The buffer formatting routines now check that the destination
4717 buffer really has enough space to add the data. This applies for
4718 both buffer formatting and unformatting
4719 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4720 unformatting was changed to accomodate following rules:
4721 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4722 sent to the function while XXX_*STRING will not allocate or copy
4723 the data into the buffer. Instead it sets the pointer from the
4724 buffer into the pointer sent as argument (XXX_*STRING used to
4725 require that the pointer must be allocated already). This change
4726 makes this whole thing a bit more consistent and more optimized
4727 (note that the data returned in the unformatting with XXX_*STRING
4728 must not be freed now). The routines return now -1 on error.
4730 o Tried to find all code that use buffer_format and buffer_unformat
4731 and added return value checking to prevent formatting and
4732 especially unformatting errors and possible subsequent fatal
4735 o Changed ske->x and ske->KEY to mallocated pointers in
4736 lib/silcske/silcske.h. Fixed possible data and memory leak.
4738 o Added return value checking to all *_parse* functions. Fixed
4739 many memory leaks as well.
4741 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4742 so that buffer overflows would not happen. All code now also
4743 checks the return value as it can fail.
4745 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Added reconnection support to server if the normal server looses
4748 its connection to the router (for example if router is rebooted).
4749 The server performs normal reconnection strategy implemented
4750 to the server. Affected file silcd/server.c.
4752 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Added new packet type SILC_PACKET_SET_MODE that is used to
4755 distribute the information about changed modes (for clients,
4756 channels and clients channel modes) to all routers in the
4757 network. Updated the protocol specification accordingly.
4759 Added functions into silcd/packet_send.c and
4760 silcd/packet_receive.c: silc_server_send_set_mode,
4761 silc_server_set_mode.
4763 Added new files silcmode.[ch] into lib/silccore that implements
4764 the encoding and decoding of Set Mode Payload. Added new type
4765 SilcSetModePayload. Moved the definitions of different modes
4766 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4768 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Oops, a little mistake in server's connection authentication
4771 protocol. The protocol is not ended with FAILURE but with
4772 SUCCESS if the authentication is Ok. :) Affected file is
4775 * Implemented NICK_CHANGE notify handling in server in the file
4776 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4777 the local clients on the channel. After the changing nickname
4778 in router environment snhould work and the [<unknown>] nickname
4779 should appear no more.
4781 The silc_server_replace_id function that receives the Replace ID
4782 payload now sends the NICK_CHANGE notify type also in the file
4783 silcd/packet_receive.c
4785 * Changed WHOIS and IDENTIFY command to support the maximum amount
4786 of arguments defined in protocol specs (3328 arguments). This
4787 fixed a bug that caused problems when there were more than three
4790 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Added extra parameter, command identifier, to the
4793 silc_client_send_command so that explicit command identifier
4796 Changed that ID list routines uses specific command identifier
4797 when sending WHOIS/IDENTIFY requests to the server so that they
4798 can be identified when the reply comes back.
4800 Affected files lib/silcclient/command.[ch],
4801 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4803 * Added `sender' argument to silc_server_packet_send_to_channel
4804 to indicaet the sender who originally sent the packet to us
4805 that we are now re-sending. Ignored if NULL. Affected file
4806 silcd/packet_send.[ch].
4808 * Added some server statistics support in silcd/server_internal.h
4809 SilcServerStatistics structure and around the server code. Also
4810 send some nice statistics information when client is connecting
4813 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Fixed channel ID decoding in server's JOIN command reply in
4816 silcd/command_reply.c
4818 * Fixed braodcasting of replace ID payload to not to send it if
4819 we are standalone server in silcd/packet_receive.c.
4821 * Fixed all channel message sending routines to not to send
4822 packets to clients that has router set, since they are routed
4823 separately in the same function earlier. Affects file
4824 silcd/packet_send.c and all channel packet sending functions.
4826 * In USERS reply, res_argv[i] are not allocated, the table
4827 is allocated. Thus changed that free the table, not its
4830 * In server's whois_check and identify_check if the client is
4831 locally connected do not send any WHOIS commands - they are not
4834 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Fixed some minor bugs in client when sending WHOIS command. The
4837 arguments was in wrong order.
4839 * Removed statis function add_to_channel from server in
4840 silcd/command.c that was previously used with the joining but
4843 * Tested USERS command in router environment successfully with two
4844 routers, two servers and two clients.
4846 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Reorganized the USERS command and command reply in client library
4849 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4850 When the command is given by user we register a pending command
4851 callback that will reprocess the command after the reply has been
4852 received from the server. When reprocessing the packet we then
4853 display the information. Thus, the USERS information is displayed
4854 now in the command callback instead of in the command reply
4855 callback. The processing of the command is same as previously
4856 when server has sent the command reply in the JOINing process.
4858 * Added to USERS command in silcd/command_reply.c to join the client,
4859 we didn't use to know about, to the channel after we've created
4860 a client entry for it. Also, for clienet we did know already still
4861 check whether it is on the channel or not and add it if not.
4863 * Removed silc_server_command_join_notify as the function and its
4866 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Changed the client's pending command handling to the same as the
4869 server's pending command handling. It is also now possible to
4870 execute command reply functions from other command reply
4871 function as the function callbacks for commands and command
4872 replies are one and same. The pending commands are not static
4873 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4874 in client connection context. Thus, pending commands are server
4875 connection specific as it is convenient.
4877 Changed the function silc_client_command_pending and
4878 silc_client_command_pending_del and added new function
4879 silc_client_command_pending_check. Removed the
4880 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4883 * Added cmd_ident, current command identifier, to the client
4884 connection context in lib/silcclient/client.h to keep track on
4885 command identifiers used in command sending. Client's command reply
4886 function handling now supports the mandatory command identifiers.
4888 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4889 funtions in client to fully support pending command callbacks.
4891 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4892 as one of the arguments to the application in the command reply
4895 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4896 before first releasing SILC but came back. Now it is removed again
4897 and should come back nomore. The FORWARDED flag was used only
4898 by the JOINing procedure by forwarding the command packet to router.
4899 Now, the JOINing procedure has been changed to more generic (due
4900 to various router environment issues) and FORWARDED is not needed
4901 anymore for anything. The protocol specification is yet to be
4904 Now, removed silc_server_packet_forward from server and the flag
4905 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4907 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Renamed NAMES command to USERS command. The NAMES was named that
4910 due to historical reasons. Now it is renamed. Also, rewrote
4911 parts of the USERS command. The nickname list is not sent anymore
4912 by the server. Only Client ID and mode lists are sent in the USERS
4913 command. Changed this also to the protocol specification.
4915 The client now resolves the names and stuff after it receives
4916 the USERS list from the server when joining to the channel.
4918 * WHOIS and IDENTIFY commands has been changed to support multiple
4919 Client ID's per command. One can now search for multiple users
4920 in the network by sending only one WHOIS or IDENTIFY command.
4921 Changed the code and the protocol specifications.
4923 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4924 uses silc_server_command_whois_parse to parse the request. */
4926 * If normal server, do not parse the WHOIS and IDENTIFY requests
4927 before sending it to the router. Saves some time.
4929 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Fixed JOIN command on client library. Wrong number of arguments
4932 used to crash the client.
4934 * Added silc_server_channel_has_global function to check whether
4935 channel has global users or not.
4937 * Added silc_server_channel_has_local function to check whether channel
4938 has locally connected clients on the channel.
4940 * The silc_server_remove_from_one_channel now checks whether the
4941 channel has global users or not after given client was removed from
4942 the channel. It also checks whether the channel has local clients
4943 on the channel anymore. If it does not have then the channel entry
4944 is removed as it is not needed anymore.
4946 * The silc_server_notify now checks on JOIN notify whether the joining
4947 client is one of locally connected or global. If it is global then
4948 the channel has now global users on the channel and that is marked
4949 to the channel entry. Also, it now saves the global client to
4950 global list who is joining and JOINs it to the channel. This is
4951 for normal server, that is.
4953 Changed silc_server_send_notify_on_channel,
4954 silc_server_packet_relay_to_channel and
4955 silc_server_packet_send_to_channel check if we are normal server
4956 and client has router set (ie. global client) do not send the
4957 message to that client, as it is already routed to our router.
4959 * Implemented LEAVE notify type handling in silc_server_notify
4962 * Tested LEAVE command in router environment successfully. Tested
4963 with two routers, two servers and two clients.
4967 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4969 * Implemented SIGNOFF notify type handling in silc_server_notify
4972 * silc_server_remove_id now removes the client entry from all channels
4973 it has joined and thusly sends SIGNOFF notify type.
4975 * Rewrote the NAMES list generation in server by removing two excess
4976 loops. The lists are created now inside one loop.
4978 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * silc_server_remove_channel_user checks now also global list
4981 for channel and client.
4983 * silc_server_new_channel_user checks now both local and global
4984 list for channel and client. Fixed a bug in client id decoding.
4985 Used to decode wrong buffer.
4987 * silc_server_channel_message checks now both local and global
4988 list for channel entry.
4990 * Tested channel joining (hence JOIN) in router environment
4991 successfully. Tested with two routers, two servers and two
4994 * Tested channel message sending in router environment successfully.
4996 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Added silc_server_save_channel_key into server.[ch] to save the
4999 received channel key in Channel Key payload processing. It is
5000 also used in JOIN command reply handling.
5002 Equivalent function silc_client_save_channel_key added into
5003 client.[ch] into client library.
5005 * Changed JOIN command reply to send information whether the channel
5006 was created or not (is existing already) and the channel key
5007 payload. Changed protocol specs accordingly.
5009 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5010 the request was sent by ID and not by nickname. Crashed on
5013 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5016 now correctly save the received data.
5018 * silc_server_free_sock_user_data now notifies routers in the
5019 network about entities leaving the network.
5021 At the same time implemented functions silc_server_remove_id
5022 and silc_server_send_remove_id to receive and send REMOVE_ID
5023 packets. The packet is used to notify routers in the network
5024 about leaving entities. The ID removed will become invalid in
5027 * Added function silc_idlist_del_server into server. Removes and
5028 free's server entry from ID list.
5030 * silc_server_private_message function now checks, if we are router,
5031 that the destination ID really is valid ID, naturally.
5033 * In router when NEW_ID packet is received (for new client) the
5034 hash of the Client ID is saved in the ID Cache but the
5035 client->nickname is set to NULL, instead of putting the hash
5038 IDENTIFY command now also checks that client->nickname must be
5039 valid. If it is not if will request the data from the server who
5040 owns the client. Added new function
5041 silc_server_command_identify_check.
5043 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5044 to set the command to already allocated Command Payload.
5046 * Tested private message sending in router environment with two
5047 routers, two servers and two clients. Fixed minor bugs and now
5050 * Fixed segfault from client's NAMES command. Used to crash if
5053 * Forwarded packets must not be routed even if it is not destined
5054 to the receiver. Changed server code comply with this.
5056 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added `require_reverse_mapping' boolean value to ServerParams
5059 structure. If TRUE (not default) the server will require that
5060 the connecting host has fully qualified domain name.
5062 If the reverse mapping is not required and hostname could not be
5063 found the IP address is used as hostname.
5065 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Implemented version string checking to both client and server.
5068 The check is incomplete currently due to the abnormal version
5069 strings used in development version of SILC.
5071 * Changed all command functions in server to use the new
5074 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Changed char *data to unsigned char *data in ID Cache system to
5077 support binary data as ID Cache data. Changed code to support
5078 binary data in lib/silccore/idcache.c.
5080 * Renamed silc_server_packet_relay_command_reply to
5081 silc_server_command_reply as it is normal packet receiving
5082 function. Rewrote the function to accept command replys for
5083 servers and not only for clients.
5085 * Mark remote router always as registered server if we are connecting
5086 to it. Otherwise, commands sent by the router to us are ignored.
5088 * All ID List find routines now returns the ID Cache Entry pointer
5089 as well if requested.
5091 * WHOIS command works now in router environment, tested with two
5092 routers, two servers and two clients.
5094 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5095 in router environment (as it is almost equivalent to WHOIS) but
5096 hasn't been tested thoroughly. Added new functions:
5098 silc_server_command_identify_parse
5099 silc_server_command_identify_send_reply
5100 silc_server_command_identify_from_client
5101 silc_server_command_identify_from_server
5103 * Disabled route cache adding because adding two different ID's with
5104 same IP replaces the old cache entry thus giving wrong route.
5105 The entry->router->connection is always the fastest route anyway
5106 so route cache may not be needed. Of course, new routes maybe
5107 established after receiving the ID when the entry->router->connection
5108 might not be anymore the most optimal.
5110 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Add route cache for received ID for fast routing.
5114 * Added silc_server_packet_route to route received packet on router
5115 that is not destined to us.
5117 * Renamed silc_server_get_route to silc_server_route_get.
5119 * Added id_string and id_string_len fields into SilcServer to
5120 include encoded ServerID for fast comparing without excess
5121 encoding of the ID's.
5123 * Cleaned up WHOIS command on server side. Added following static
5126 silc_server_command_whois_parse
5127 silc_server_command_whois_check
5128 silc_server_command_whois_send_reply
5129 silc_server_command_whois_from_client
5130 silc_server_command_whois_from_server
5132 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5133 arguments in command replies. All command functions should be
5134 updated to use this macro.
5136 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Minor typo fixes on command reply handling on server.
5140 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Added silc_server_command_add_to_channel internal routine to add
5143 the client to the channel after router has created the channel and
5144 sent command reply to the server.
5146 * Added generic silc_server_send_command to send any command from
5149 * Use static buffer with ID rendering instead of duplicating data.
5151 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Fixed a channel user mode bug when joining to a channel server gave
5154 everybody channel founder rights, oops.
5156 * We mark ourselves as the router of the incoming server connection
5157 if we are router ourselves. This way we can check in some packet
5158 sending functions whether it is locally connected server. For
5159 incoming router connections we put NULL.
5161 * For router sending packets locally means now always sending the
5162 packet cell wide; to local clients and local servers. For normal
5163 server sending packet locally means sending it to only local
5166 * Fixed the JOIN command to really work in router environment. If the
5167 channel is created it is always created by the router. Router is
5168 also responsible of making the initial joining to the channel,
5169 sending JOIN notify to the sending server and distributing
5170 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5171 does not exist server doesn't do anything else but forward the
5172 command to the router which performs everything.
5174 * Added silc_server_send_channel_key function to send the Channel Key
5177 * Added silc_server_create_channel_key to create new channel key. The
5178 channel key is now re-generated everytime someone joins or leaves
5179 a channel, as protocol dictates. Note: channel->key_len is the
5182 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5185 packet_receive.[ch] to separate packet sending and receiving
5186 routines. The server.[ch] now includes everything else including
5187 actual packet processing (writing and reading data) and other
5190 Renamed silc_server_private_message_send_internal to
5191 silc_server_send_private_message. The routine is still though
5192 used only to relay private messages as server does not send
5193 private messages itself.
5195 Renamed silc_server_new_channel to silc_server_create_new_channel
5196 and added new function sicl_server_new_channel that handles the
5197 incoming New Channel packet. Added also new sending function
5198 silc_server_send_new_channel to send New Channel Payload.
5200 * Added new function silc_server_notify to process incoming notify
5201 packet to the server/router. Server may then relay the notify
5202 to clients if needed.
5204 * Added new function silc_server_new_channel_user to process incoming
5205 New Channel User packet. Router will redistribute the packet and
5206 send JOIN notify to its local clients and locally connected servers
5207 if needed. Normal server will send JOIN notify to its local client
5208 on same channel when received this packet. Added also corresponding
5209 sending function silc_server_send_new_channel_user to sent the
5212 * Added boolean route argument to send_notif_to_channel and
5213 packet_send_to_channel functions to attempt to route the packet
5214 if it is TRUE and send only locally if it is FALSE.
5216 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * silc_server_replace_id now broadcasts the received replace ID
5219 packet if it is not broadcast packet already. The router must
5220 broadcast to inform other routers about changed ID.
5222 * Added backpointer to server's router into SilcServer context in
5223 silcd/server_internal.h.
5225 * Fixed silc_server_packet_broadcast to send correct broadcast
5228 * The channel key is now distributed to the local client as soon
5229 as it is received from the router (in router environment) so that
5230 no other packet may be sent for the channel until client has
5233 * silc_server_remove_channel_user now broadcasts the received
5234 Remove Channel User packet if it is not broadcast packet already.
5235 The router must broadcast to inform other routers about removed
5238 * Added users field into SilcPacketContext that is a reference count
5239 of the context. One can increase the reference count by calling
5240 silc_packet_context_dup which is now changed to just increase the
5241 reference count instead of duplicating the data. The reference
5242 count is decresed by calling silc_packet_context_free that will
5243 free the data after the reference count hits zero.
5245 For now on the packet context and everything allocated into it
5246 (including the raw packet from network) must be freed by calling
5247 the new silc_packet_context_free function. Added also new function
5248 silc_packet_context_alloc that must be used now to allocate the
5249 context. This also means that if a routine is asynchronous from
5250 silc_[client/server]_packet_parse_type the packet context must
5251 be duplicated by calling silc_packet_context_dup. Otherwise it
5252 gets free'd after silc_[client/server]_packet_parse_type returns.
5253 Also, one must remember that if packet is duplicated then its
5254 reference count must be decresed by calling the free function as
5255 many times as it was duplicated.
5257 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5258 from both client and server.
5260 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Made joining to a channel working in router environment.
5264 * Cleaned up JOIN command on server side and create function
5265 silc_server_command_join_channel internal routine to make the
5268 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Changed silc_command_pending list to SilcDList. Also, added
5271 `ident' field to SilcServerCommandPending structure to identify
5272 the reply and to call correct callback.
5274 Added silc_server_command_pending_check function to replace the
5275 corresnponding macro. The silc_command_pending list is not
5278 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5279 to set identifier to previously allocated Command Payload. It
5280 is used to set identifier for command when resending Command
5283 * Added silc_command_payload_encode_payload to encode Command
5284 Payload buffer from SilcCommandPayload structure.
5286 * Added silc_argument_payload_encode_payload to encode Argument
5287 payload buffer from SilcArgumentPayload structure.
5289 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Changed WHOIS command to support router connection on server side.
5292 The whois request is always sent to router unless the server is
5293 standalone server. After server has received the reply from the
5294 router will it send the reply to the client.
5296 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5297 broadcast received broadcast packet. The function is used only
5298 by router. The broadcast packet is always sent to the router's
5301 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5302 render given ID to printable string, for log files for example.
5304 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Made basic router to router connections working. At least they
5307 can now connect to each other but nothing really works the way
5308 they are supposed - yet.
5310 * Added new initiator token to RouterConnection configuration
5311 file in silcd/serverconfig.[ch]. It is used to tell whether we
5312 are the initiator to the remote router or whether we'll expect
5313 the other end to connect.
5315 * Moved registering of listener task to silc_server_init, hence
5316 the server starts listenning as soon as it is run, even if it
5317 does not have connections to other routers. Let's see how well
5320 * Changed default connection retry timeouts for more suitable in
5323 * Removed cipher and such arguments from silc_idlist_add_client
5324 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5325 Added new function silc_idlist_add_data to add the keys and stuff
5328 * Added SilcIDListData structure and added it to SilcClientEntry
5329 and SilcServerEntry as their first field in the structure. This
5330 way we can explicitly cast the ID entries to the SilcIDListData
5331 structure and get common data for the entries. In past, we had
5332 to first check what type of connection it is and then cast it to
5333 correct ID entry type. Now, we can directly cast the opaque
5334 pointer to the SilcIDListData (no matter what ID entry it actually
5335 is) and get the data needed.
5337 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5340 in some circumstances even if threre were timeout tasks, though not
5341 IO tasks, but tasks anyway. Now fixed.
5343 * Defined SilcServerConnection structure to hold connection specific
5344 stuff about directly connected servers and routers. The definition
5345 is currently in silcd/server_internal.h. I thought about having
5346 a bit more important role fro this struct but for now it is used
5347 only when connecting to other server (or router actually).
5349 * Added connecting retry support in server when connecting to
5350 router(s). The retry feature implement exponential backoff
5351 algorithm. Also, added SilcServerParams structure to hold default
5352 parameters for server. For now, it include these retry settings
5353 and are hard coded. After server is moded to be as Silc Server
5354 Library this structure will be more important.
5356 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Changed client librarys channel->clients table to SilcList and
5359 changed code accordingly.
5361 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Changed client's channel table to SilcList and changed code
5364 accordingly. Also changed SilcChannelClientEntry to include back-
5365 pointer to the channel so that client entry can use that structure
5366 as list as well and we have fast cross-reference to the channel.
5367 This change dramatically decreased the complexity of channel
5368 handling with client entry and vice versa (removed one extra
5369 loop when searching for channel entry from many functions).
5371 * Changed server->sim from table to SilcDList and changed code
5374 * NAMES command can now be used from user interface. It will show
5375 the user list on the channel, neatly.
5377 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5378 Code now saves realname of the user if it becomes available.
5380 * Renamed configure.in to configure.in.pre and made ./prepare
5381 script to automatically add correct version string to
5382 configure.in which it creates from configure.in.pre.
5384 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * NAMES command reply now shows users mode with the nickname when
5389 * Moved silc_client_ch[u]mode[_char] functions from
5390 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5391 place sucks, they are utility functions and should be in some
5394 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5396 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5399 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Added TRQ (efficient deque and list library) into lib/trq. This is
5404 a very good list library that is currently used in the SILC. Defined
5405 SilcList API over the library because I didn't like the API very
5406 much. See lib/trq/silclist.h for the API and examples of how to
5407 use the API. Fixed various places in the code to use the new
5408 SilcList API. The SilcList is meant for lists that has a structure
5409 already defined as a list. It is not suitable to add just some
5410 context to the list (in TRQ, the context is the list actually).
5412 So, I defined SilcDList that can be used for the purpose where
5413 predefined list structure does not exit. This can be used as
5414 such list. Now some context just can be added to the SilcDList.
5415 Currently this list is not used in the SILC just yet, though there
5416 are a lot places where this can replace dynamically allocated
5417 tables and I will fix these places, later, to use SilcDList.
5418 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5419 and use TRQ internally).
5421 Also fixed some annoying warning messages that the original TRQ
5422 code generated. Also minor changes to TRQ's Makefile.in.
5424 * Added support for querying by Client ID to both WHOIS and
5425 IDENTIFY commands into server, as required by the protocol.
5427 * Removed method function pointers from SilcBuffer structure. They
5428 weren't used to anything and just increased the context size for
5429 no good reason. This change also made silc_buffer_alloc and
5430 silc_buffer_free functions inline functions.
5432 * Disabled command flooding detection support until it's fixed so
5433 that it accepts commands in but does not execute them more than once
5436 * Added silc_net_localhost(), to return local hostname, into
5437 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5438 that must be initialized before calling silc_client_init.
5440 * Added new function: silc_server_send_notify_on_channels to send
5441 notify messages to all channels client has joined. It is assured
5442 that the message is sent only once per client.
5444 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5445 lib/silcutil/silcutil.[ch] as silc_format function. The new
5446 function is generic and is used by server as well, not only by
5447 the logging routines.
5449 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5450 the provided version string was not acceptable. Added new function:
5451 silc_ske_check_version into lib/silcske/silcske.h. The function
5452 must be implemented by the application (client or server) and it
5453 does not reside in the SKE library. The function checks the version
5454 string remote end sent.
5456 * Added back pointers (to opaque context and to SilcSocketConnection)
5457 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5459 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5460 duplicate packet context structure.
5462 * Changed `notify' client operation to send same arguments as client
5463 receives from server except for ID's. ID's are mapped to correct
5464 ID entry and that is returned. Also, if channel entry is not sent
5465 by server but the notify is for channel the channel entry is sent
5466 to application (otherwise application doesn't know that it is for
5467 channel (library gets it from packet's Destination ID)).
5469 * Added silc_client_remove_from_channels into client library to
5470 remove a client from all channels it has joined to. Used when
5471 received SIGNOFF notify from server. Added also new function
5472 silc_client_replace_from_channels to replace old ID entry with
5473 new ID entry on all channels. Used when received NICK_CHANGE
5476 * Fixed ID Cache list handling in silc_idlist_get_client in
5477 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5478 to get (or query) client by ID.
5480 * Updated TODO list.
5482 * Added connection authentication status message defined by the
5483 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5484 support for these into the code in client and server side.
5486 * Added generic function silc_client_send_command to send any command
5487 with variable argument list. Application should use this function
5488 to send commands if the command functions provided by the library
5489 does not suite for the application's user interface needs.
5491 * Added new `failure' client operation. Application is notified about
5492 received failure packet if client is executing a protocol. In this
5493 case the protocol's execution has failed.
5495 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5496 is required by the protocol.
5498 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5499 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5502 * Added status flag to SilcSKE object to indicate realtime status
5503 of the SKE protocol.
5505 * Application receives now exactly same command reply arguments as
5506 the library receives from server. However, if ID is received the
5507 corresponding ID entry is returned to the application (eg. Client
5508 ID is mapped to correct SilcClientEntry entry and that is returned).
5509 Changed command_reply client operation due to this change.
5511 * Changed all ID's in commands and in command replys as ID Payloads.
5512 Change affected both client and server side codes.
5514 All ID's sent in SILC network (with execption of ID's in SILC
5515 Packet header) are sent in ID Payload to support variable length
5518 * Server now notifies nick changes and notifies all clients on
5519 the channels about the new nickname (about the new Client ID,
5522 * Implemented CMODE command to change channel modes. Supports all
5523 channel modes defined by the protocol specs except ban and invite
5524 lists. (Also, private channel key mode is supported but support for
5525 setting private channel key in client is missing, thus, this mode
5526 has no effect on client side (except that server requires that the
5527 client uses private channel key and normal channel traffic does not
5530 Also, invite mode works per se, but INVITE command does not work
5531 yet correctly, so you can set channel as invite only channel but
5532 inviting clients to the channel does not work (it is yet to be
5533 thought what's the best way to do it).
5535 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5536 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5537 Implemented CUMODE command to change user's mode on the channel.
5538 Supports all modes defined by the protocol specs.
5540 * Added NAMES command reply to return users modes on the channel.
5542 * Removed unnecessary and slow ciphers from lib/silccrypt.
5544 * Set SO_KEEPALIVE option to connection sockets by default.
5546 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5548 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5549 redefined the Notify Payload into protocol specs.
5551 * Added silc_id_payload_parse_id to get ID directly from raw
5554 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5557 accept searching by Client ID as well.
5559 * Added support for LEAVE and SIGNOFF notify types in client library.
5561 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5562 to parse ID Payload from raw data.
5564 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added flags parameter into silc_ske_assemble_security_properties
5567 function in lib/silcske/silcske.[ch].
5569 * Changed notify client operation to fit better for notify messages
5570 sent by server. The notify payload received from server is now
5571 passed to the application (after parsing it to SilcNotifyPayload).
5572 It is application's responsibility to retrieve the arguments
5573 from the payload and show the message the way it wants. The message
5574 sent by server is implementation specific.
5576 * Changed public keys to comply with the protocol specification.
5577 Old public keys are not supported anymore and are not compatible.
5579 * Removed nickname from Channel Payload as the latest draft removed
5580 it. The client must resolve the nickname from the NAMES command
5581 reply received when it joined the channel.
5583 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5585 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Fixed some errors in protocol specification drafts.
5589 * Created lib/silccore/silcnotify.c to implement Notify Payload
5590 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5591 generic payloads described by protocol specifications. The file
5592 includes implementations for ID Payload and Argument Payload.
5594 * Changed Command Payload implementation to use the new Argument
5595 Payload. Changed command_xxxx_payload to command_payload_xxxx
5596 to comply with SILC coding conventions.
5598 * Added suppport for Argument Payload handling in Notify Payload
5599 implementation as protocol requires it. Added the new support
5600 into server and client lib as well.
5602 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added support for multiple nicknames on same channel. [n] is
5605 added locally to the nickname if there are more than one same
5606 nicknames on the channel.
5608 * Server now sends all nicknames that matched WHOIS request.
5609 Client also shows the list received from server.
5611 * Added TOPIC command to client side. User can now set and show
5612 current topic on channel.
5614 * Added MOTD command to client and server. Also, server sends the
5615 motd when client connects to the server.
5617 * Changed version strings to comply ISO 8601.
5619 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Fixed protocol error handling in client library. It should now
5622 cope even if the SKE fails for some reason.
5624 * Made new protocol specification drafts for submitting to IETF.
5626 * Implemented TOPIC command to server in silcd/command.c.
5628 * Added two new notify types into lib/silccore/silcnotify.h:
5629 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5630 notify nickname change and topic setting/change on a channel.
5632 * API change of command_reply operation in client library. The
5633 application gets now the status type received from server as well.
5635 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5639 * Cras fixed and optimized the packet handling even further and
5640 it should work now. Minor change to the prototype of function
5641 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5643 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added new function into lib/silcutil/silcschedule.[ch]:
5646 silc_schedule_with_fd to select() a specified fd. The function
5647 returns after timeout expires or data arrives or goes. The
5648 function is used by packet routines to wait that all data is
5649 received from network.
5651 * Fixed data reading from network in lib/silccore/silcpacket.c.
5652 The code now assures that all data is read from the fd and then
5653 continues packet processing. This was a bug fix since the code
5654 used to drop some data in some circumstances.
5656 * Added new function into lib/silcclient/client.[ch]:
5657 silc_client_start_key_exchange to start key exchange after
5658 connection has been established to server. The code internally
5659 now uses this funtion but its main purpose was to provide it
5660 for applications that perform their own connecting. After
5661 application has created a connection it merely calls this
5662 function to start the key exchange between client and server.
5663 The library takes care of everything else after that.
5665 Updated also lib/silcclient/README to explain the usage of
5668 * Do not send to application information that connection has
5669 been established. Application gets notified it by connect
5672 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Applied cras's patch to add silc_schedule_one function. The
5675 function runs scheduler once and returns.
5677 * Fixed the scheduler after cras messed it up. The timeout
5678 handling works now as it's supposed to work.
5680 * Added into lib/silccore/ silcnotify.h to include notify
5681 message types support. Changed silc_server_send_notify*
5682 functions, in server.[ch], to support those new notify types.
5683 Added the support for the notify types into client library,
5684 as well. Added new notify client operation into ops.h in
5687 * Changed silc_server_packet_send_to_channel to send normal
5688 packets instead of just channel message packets. The function
5689 is now used to send the notify packets to channels. It is not
5690 used to send channel message packets anymore, as server never
5693 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5694 va_arg()s as it seems to require it nowadays. I guess, if SILC
5695 is compiled with older va_arg() the new code should work anyway.
5697 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Splitted core library. Core library (lib/silccore) includes
5700 now only SILC protocol specific core (and common) components.
5701 Created new utility library (lib/silcutil) that includes more
5702 generic purpose stuff. The stuff for util library was taken
5703 from the old core library. This was minor and easy split.
5705 * Created SILC Client Library (lib/silcclient) that includes
5706 implementation of the SILC client without user interface. This
5707 was major move from silc/ directory. The code has been changed
5708 so that it is transparent towards the user interface. The
5709 silc/ directory includes now the same user interface as before
5710 and it uses the new client library. Read lib/silcclient/README.
5711 Basicly, the client library performs everything else related
5712 to SILC except user interface handling. Also, configuration
5713 files are considered to be part of user interface and library
5714 does not handle them.
5716 This change also changed a lot of structures, function naming etc.
5717 Most important change was that SilcClientWindow object was
5718 renamed to SilcClientConnection in the client library. Created
5719 also new file lib/silcclient/ops.h. Also added new files
5720 silc/local_command.[ch] and silc/client_ops.[ch].
5722 All these changes were made to make it easier for user interface
5723 designers to create what ever user interface for the SILC client
5726 It is also expected that the server will be moved to lib
5727 directory as well and SILC Server Library will be created;
5728 sometimes in the future.
5730 * Removed Local commands from lib/silccore/silccommand.h as
5731 they are application specific and new client library does not
5732 handle any of those anymore.
5734 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5735 old client implementation in silc/.
5737 * Added support for callback functions in SILC_LOG_* macros.
5738 Application can now set its own callbacks that will be called
5739 instead of using the default functions that will always print
5740 the debug messages to stderr (or stdout). Also, debugging can
5741 now be disabled by setting silc_debug to FALSE and re-enabled by
5742 setting it to TRUE. Note, that logging will still work even
5743 if debugging is disabled.
5745 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5746 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5747 silc_log_reset_debug_callbacks.
5749 * To enable debugging in silc client one must give now -d
5750 option on command line.
5752 * Changed silc_schedule_init to automatically allocate task queues
5753 if they are not allocated before calling it.
5755 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added GMP 3.1 into math library.
5759 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5762 a channel in SILC network. The packet is used by servers and
5763 routers to notify other routers that user has left a channel.
5764 This little feature was missing until now. Added the feature
5765 to protocol specification as well.
5767 Added functions: silc_server_send_remove_channel_user and
5768 silc_server_remove_channel_user into server.[ch].
5770 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5771 lib/silccore/silcpacket.h. However, they are not implemented
5774 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Fixed joining to a channel and sending channel messages
5777 between server and router. The channel message sending should
5778 now work inside a cell.
5780 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Fixed the private message sending between server and router.
5783 The private message sending should now work inside a cell.
5785 * Added silc_server_replace_id into server.[ch] to replace
5786 existing ID in the SILC network.
5788 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5789 and silc_idlist_replace_server_id into idlist.[ch] in server.
5791 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed the server to server connections. Server can again now
5794 connect to router. Router to router connections probably does
5797 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Added dynamic protocol registering support. Now protocols can
5800 registered and unregistered on the fly. Patch by cras.
5802 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Added lib/contrib directory to hold routines that some platforms
5805 don't have but are needed by SILC.
5807 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5808 into lin/contrib to provide getopt() and getopt_long() for
5809 those who don't have it.
5811 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Added AWAY command to client. When away message is set and
5814 client receives a private message packet the client automatically
5815 replies to the sender with the away message.
5817 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5818 bug seemed to be the cause of recent problems when compiling
5821 * Added version detection support to SKE protocol specification
5822 and added the new changes to the SKE implementation as well.
5823 There were other minor changes in the SKE protocol as well.
5825 Many changes in lib/silcske/silcske.[ch] and in
5826 lib/silcske/payload.[ch].
5828 * Added ^U functionality, clear input line. Patch from cras.
5830 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Mainly small bugfixes on core library. Fixed some debugging
5833 logging and buffer overflow in silclog.c.
5835 * Updated config.sub and config.guess on the distribution tree.
5837 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Added command lagging support in server. Client may execute
5840 commands now only once in two seconds.
5842 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Optimized packet reception. MAC computation and checking is now
5845 also more optimized. A lot previously duplicated code is now
5846 used as generic by both client and server.
5848 * Fixed key pair generation in clientutil.c
5850 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Added into lib/silccore/silcbufutil.[ch] new function;
5853 silc_buffer_realloc.
5855 * Moved generic packet sending/encryption functions to
5856 lib/silccore/silcpacket.[ch] from client and server. Some
5857 rewriting of the functions.
5859 * Moved all generic packet reception/decryption functions to
5860 lib/silccore/silcpacket.[ch] from client and server. The
5861 packet processing is now much cleaner in both client and server.
5862 These were major changes in both client and server.
5864 * Created many common functions in server to do packet sending.
5865 Previously code were duplicated a lot, this has been removed
5868 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Rewrote major parts of the ID cache system. Don't know
5871 whether it is better now or not but at least the API is more
5874 * Major rewrite on ID cache stuff on client because of the ID
5875 cache API changes. Added idlist.c to client.
5877 * Also major rewrite on ID cache stuff on server as well.
5878 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5879 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5880 in hand, instead they are all put into the ID cache system now.
5881 All server_idlist_* routines uses ID cache now instead of
5882 traversing its own lists (those lists does not exist anymore).
5883 SilcIDList though still exists. Also, SilcXXXEntry's are
5886 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Finally made the SKE implementation compliant to the protocol
5889 specification. All mp integers are now binary encoded as
5890 opposed being HEX encoded.
5892 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5895 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5896 functions: silc_[encode/decode]_pem. Also added function
5897 silc_encode_pem_file to PEM encode with newlines ('\n') for
5900 * SILC public keys are now encoded either PEM or binary. Same
5901 option is for private keys as well. By default private keys
5902 are binary encoded and public keys PEM encoded. Silly HEX
5903 encoding were removed.
5905 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5906 function to create fingerprints.
5908 * Fixed a bug in SHA1; does not change the original data anymore.
5910 * Partly implemented INFO command on client and server side.
5911 Fixed CLEAR command. Changes to SERVER command; show current
5912 server(s) when giving command without arguments. Added
5913 VERSION command to client.
5915 * Added check to server that unregistered connections cannot
5916 execute commands (unless it is specificly allowed).
5918 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Fixed screen refresh.
5922 * Fixed channel joining bug from client. On some circumstances
5923 client tried to join to a channel it had already joined.
5925 * Added public key verification process into client's protocol.c.
5926 The client now verifies the public key from user and saves
5927 it into ~./silc/serverkeys/ directory.
5929 Added into: clientutil.[ch]: silc_client_verify_server_key.
5931 * Changed SKE protocol's silc_ske_initiator_finish function
5932 to accept callback function that verifies the received public
5933 key. Removed old silc_ske_verify_public_key function.
5935 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5937 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5938 silc_pkcs_private_key[_data]_set.
5940 * Made the password and public authentication more cleaner in
5941 server's protocol.c.
5943 * Removed historic and obsolete protocol `channel_auth' from
5944 both client and server.
5946 * Removed wrong way of sending command status messages from
5947 server to client in server's command.c. The old way violated
5948 protocol specification.
5950 Changes to silccore/silccommand.[ch]: removed
5951 silc_command_encode_status_payload -> not needed anymore,
5952 changed silc_command_encode_payload_va to accept extra
5953 argument on variable argument list. The argument type must
5954 now be provided to the function. Also, added new function:
5955 silc_command_encode_reply_payload_va which is same as
