1 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Save fingerprint in WHOIS command reply in server.
4 Affected file silcd/command_reply.c.
6 * Fixed NICK commands pending callback registration.
7 Affected file lib/silcclient/command.c.
9 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
11 * Use ++server->cmd_ident when sending commands in server,
12 instead of random number. Affected file silcd/command.c.
14 * Fixed GETKEY command reply to call actually GETKEY pending
15 command callbacks. Affected file silcd/command_reply.c.
17 * A bit stricter check for nicknames. Check for same nickname
18 in NICK command also. Affected file silcd/command.c.
20 * Do not call INFO command everytime client ID changes, only
21 during first connecting. Affected file lib/silcclient/client.c.
23 * Set the new nickname only after successful command reply for
24 NICK command is returned by server. Affected file
25 lib/silcclient/command.c.
27 * Remove nicknames from nicklist during server_signoff notify.
28 Should fix /NAMES bit more. The affected file is
29 irssi/src/silc/core/silc-channels.c.
31 * Added `fingerprint' field to the SilcIDListData in the
32 silcd/idlist.h to hold the fingerprint of the client's
35 Send the fingerprint of the client's public key in WHOIS
38 Affected files silcd/command.c, and silcd/idlist.[ch].
40 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
41 create fingerprint from given data.
43 * Show the fingerprint of the client's public key in WHOIS.
44 Affected files irssi/src/module-formats.[ch] and
45 irssi/src/silc/core/client_ops.c.
47 * Format the multiple same nicknames also during JOIN and
48 NICK_CHANGE notifys. Affected file is
49 lib/silcclient/client_notify.c.
51 * Do not print error on screen for invalid private message
52 payload since it can come if someone is sending private
53 messages with wrong key. Affected file
54 lib/silccore/silcprivate.c.
56 * Fixed multiple concurrent /PING crash. Affected file
57 lib/silcclient/command.c.
59 * Changed the wrong ID encoding. All IP addresses must be
60 in MSB first order in encoded format. They were encoded
61 wrong and was in LSB format. Affected files are
62 silcd/serverid.c, lib/silcutil/silcutil.c.
64 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
66 * Call the `connect' client operation through the scheduler
67 in case of error. Affected file lib/silcclient/client.c.
69 * Call the `failure' client operation even if the error
70 occurred locally during a protocol. Affected file is
71 lib/silcclient/protocol.c.
73 * Added support of sending LIST command to router from normal
74 server. This way normal server can get list of all channels
75 in the network too. Fixed the channel list sending in the
76 server too. Affected files are silcd/command.c, and
77 silcd/command_reply.[ch].
79 * Added silc_server_update_channels_by_server and
80 silc_server_remove_channels_by_server. They are used during
81 disconnection of primary router and in backup router protocol.
82 Affected file silcd/server_util.[ch], silcd/server.c and
83 silcd/server_backup.c.
85 * Fixed channel adding to global list in IDENTIFY command
86 reply in server. Affected file silcd/command_reply.c.
88 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
90 * If the incoming packet type is REKEY or REKEY_DONE process
91 that packet always synchronously. Fixes yet another MAC
92 failed error on slow (dialup) connections. Affected file
93 lib/silcclient/client.c and silcd/server.c.
95 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Call check_version SKE callback for initiator too. Affected
98 file lib/silcske/silcske.c.
100 * Implemented fix for security hole found in the SKE that was
101 fixed in the specification few days back; the initiator's
102 public key is now added to the HASH value computation.
103 Added backwards support for the old way of doing it too, for
104 old clients and old servers. Affected file is
105 lib/silcske/silcske.c.
107 * Enabled mutual authentication by default in SKE. If initiator
108 is not providing mutual authentication the responder will
109 force it. This will provide the proof of posession of the
110 private key for responder. The affected files are
111 lib/silcclient/protocol.c and silcd/protocol.c.
113 * Do not cache anymore the server's public key during SKE.
114 We do mutual authentication so the proof of posession of
115 private key is done, and if the server is authenticated in
116 conn auth protocol with public key we must have the public
117 key already. Affected file silcd/protocol.c.
119 * Added new global debug variable: silc_debug_hexdump. If
120 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
121 file lib/silcutil/silclog.[ch].
123 * Fixed compilation warning due to char * -> const char *.
124 Affected files lib/silcutil/silcnet.h, and
125 lib/silccore/silcauth.[ch].
127 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
129 * Fixed CMODE command when new channel key was created. If
130 the creation failed the old key was removed. Next time giving
131 same command would crash the server since the old key was
132 freed already. Affected file silcd/command.c.
134 * Fixed the silc_server_announce_get_channels to not crash
135 on reconnect. Affected file silcd/server.c.
137 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
139 * Added silc_log_set_debug_string function to set a regex
140 string to match for debug output. Only the function names,
141 or filenames matching the given debug string is actually
142 printed. This way it is possible to filter out those debug
143 strings that user is not interested in.
145 Fixed a bug in silc_string_regexify.
147 Affected files lib/silcutil/silclog.[ch], and
148 lib/silcutil/unix/silcunixutil.c.
150 * Changed the -d options in both server and Irssi SILC client
151 to take the debug string as argument. Affected files
152 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
154 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
156 * Added silc_hash_babbleprint to create a Bubble Babble
157 Encoded fingerprint. The encoding is developed by Antti
158 Huima (draft-huima-babble-01.txt), and it creates human
159 readable strings out of binary data. Affected file
160 lib/silccrypt/silchash.[ch].
162 * Print the babble print now in addition of fingerprint as well
163 in Irssi SILC client. Affected files are
164 irssi/src/fe-common/silc/module-formats.[ch],
165 irssi/src/fe-common/silc/core/client_ops.c.
167 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
169 * Fixed a security problem found in SKE. The initiator's
170 public key too is now added to the HASH hash value creation
171 which is signed by the responder to create the SIGN value.
172 This will prevent anyone in the middle to lie to the responder
173 about the initiator's public key. If this is done now, the
174 man in the middle will get caught. Updated the protocol
177 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Better installation directory handling. Configure module
180 paths and other paths automatically to example_silc* files
181 in doc/. A patch by toma.
183 * Fixed compiler warning from MPI library, and from SILC RNG.
186 * Added SILC_SERVER_PID_FILE to define the pid file for server.
187 It can be configured with ./configure. A patch by toma.
189 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
191 * Find correct make to use in prepare-clean. A patch by
192 toma. Affected file prepare-clean.
194 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
196 * Added irssi variables use_auto_addr, auto_bind_ip,
197 auto_bind_port and auto_public_ip.
199 * Changed the interface for silc_client_send_key_agreement
200 in lib/silcclient/silcapi.h
204 irssi/src/silc/core/silc-core.c
206 lib/silcclient/silcapi.h
207 irssi/src/silc/core/silc-channels.c
208 lib/silcclient/client_keyagr.c
211 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
213 * Added silc_pkcs_public_key_compare to compare two
214 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
216 * Check that the client who set the founder mode on the
217 channel is the same client that is giving the founder
218 mode to itself. It is done by comparing the saved public
219 key (it is saved even in the authentication is passphrase).
220 Affected file silcd/command.c.
222 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
224 * Do not process packet for disconnected socket connection.
225 Affected file lib/silccore/silcpacket.c.
227 * Process the DISCONNECT packet through scheduler in the
228 client library. Affected file lib/silcclient/client.c.
230 * Fixed the silc_client_packet_parse to not to increase
231 the packet sequence number if the conn->sock and the
232 current socket connection is not same. This can happen
233 for example during key agreement when the conn includes
234 multiple socket connections (listeners). Affected file
235 lib/silcclient/client.c.
237 * The sender of the file transfer request now provides also
238 the pointer (listener) for the key exchange protocol. If
239 the listener cannot be created then it sends empty key
240 agreement and lets the receiver provide the listener.
242 Added `local_ip' and `local_port' arguments to the
243 silc_client_file_send. If they are provided they are used,
244 if not then it will attempt to find local IP address, if
245 not found or bind fails then the remote client will provide
248 Affected files are lib/silcclient/client_ftp.c and
249 lib/silcclient/silcapi.h.
251 * Extended the FILE SEND command to support defining the
252 local IP and port for key exchange listener. They are
253 optional. Affected file irssi/src/silc/core/silc-servers.c.
255 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
257 * Defined to WHOIS command reply the sending of fingerprint
258 of the client's public key (if the proof of posession of the
259 corresponding private key is verified by the server).
260 Updated to the protocol specification.
262 * Added support of receiving the client's public key's
263 fingerprint in command reply in client library. Affected
264 file is lib/silcclient/command_reply.c, and
265 lib/silcclient/idlist.[ch].
267 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Do not send over 128 chars long nickname to the server
270 in NICK command. Affected file lib/silcclient/command.c.
272 * Do not send over 256 chars long channel names to the server
273 in JOIN command. Affected file lib/silcclient/command.c.
275 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Assure that silc_server_close_connection cannot be called
278 twice for same socket context. Affected file is
281 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
283 * Send error message to application if opening file for
284 writing during file transfer fails. Affected file is
285 lib/silcclient/client_ftp.c.
287 Remove all file transfer sessions for a client that we're
288 removing from ID cache.
290 Affected file is lib/silcclient/client_ftp.c.
292 * Fixed silc_net_addr2bin to return correct address. Affected
293 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
295 * Fixed file transfer session removing on signoff notify.
296 Affected file irssi/src/silc/core/silc-servers.c.
298 * Added the SilcClientFileError to be returned in the monitor
299 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
300 Affected file lib/silcclient/silcapi.h.
302 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
304 * Fixed a crash in silc_client_ftp_free_sessions and
305 silc_client_ftp_session_free_client. Affected file
306 lib/silcclient/client_ftp.c.
308 * Added `disabled' field in the SilcChannelEntry in the server
309 to indicate if the server entry is disabled. Affected file
310 silcd/idlist.h, silcd/command[_reply].c.
312 * SILC server adds now /var/run/silcd.pid everytime it is
313 started. Affected file silcd/silcd.c.
315 * Added silc_server_packet_send_clients to send a packet to
316 the provided table of client entries. Affected file
317 silcd/packet_send.[ch].
319 * Fixed a crash in client resolving in client_prvmsg.c in
320 client library. Affected file lib/silcclient/client_prvmsg.c.
322 * Do not actually remove the client directly from ID cache
323 during SERVER_SIGNOFF, but invalidate it. This way we
324 preserve the WHOWAS info for the client. Affected file
327 * Fixed SERVER_SIGNOFF notify handling in the server. The
328 server is now able to process incoming SERVER_SIGNOFF notify
329 for a server that it doesn't even know about. It will remove
330 the clients provided in the notify. Affected file
331 silcd/packet_receive.c.
333 * Check for partial packet in data queue after every packet that
334 was found from the queue. Return and wait for more data if
335 there is partial data in queue. Affected file is
336 lib/silccore/silcpacket.c.
338 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
340 * Added SilcClietFileError enum to indicate error in
341 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
342 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
343 Affected files lib/silcclient/silcapi.h and
344 lib/silcclient/client_ftp.c.
346 * Check that newsize in silc_buffer_realloc is larger than
347 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
349 * Added better monitor of file transfers. It now monitors
350 key agreement protocol during the file transfer too. Added
351 error reporting too. Affected files
352 irssi/src/silc/core/silc-servers.c,
353 irssi/src/fe-common/silc/module-formats.[ch].
355 * Wrote a help file for FILE command.
357 * Added silc_rng_global_get_byte_fast to get not-so-secure
358 random data as fast as possible. Random data is read from
359 /dev/urandom if available and from the SILC RNG if not
360 available. It is used in padding generation. Affected file
361 lib/silccrypt/silcrng.[ch].
363 * All packets in client library are now processed synchronously.
364 Optimized packet processing a lot. Affected file
365 lib/silcclient/client.c.
367 * All server connection packets are processing synchronously
368 now in server, to optimize packet processing. Affected file
371 * Include files are installed now only in Toolkit distribution
372 if make install is given. Affected files: all Makefile.am's.
374 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
376 * Assure that silc_client_notify_by_server_resolve does not
377 resolve the client information multiple times. If it cannot
378 be found by the first it cannot be found at all. Affected
379 file lib/silcclient/client_notify.c.
381 * Fixed WHOWAS command reply calling. Affected file
382 lib/silcclient/command_reply.c.
384 * Removed all references to silc_idlist_get_client from the
385 Irssi SILC client since that call is internal call used by
386 the library. The Irssi SILC client will use now client
387 retrieval functions found in silcapi.h.
389 * Fixed a bug in resolving nickname info before sending
390 private message. It used freed memory. Affected file
391 irssi/src/silc/core/silc-servers.c.
393 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
395 * Assure my_channels statistics cannot go negative in server.
396 Affected files silcd/server.c, silcd/server_util.c.
398 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
400 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
402 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
404 * Win32 Toolkit changes. Affected files
405 win32/silc.dsw, win32/libsilc/libsilc.def,
406 win32/libsilcclient/libsilc.def,
407 lib/silcutil/silcutil.c, and
408 lib/sftp/sftp_fs_memory.c.
410 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
412 * Added silc_net_localip to return local host's IP address.
413 Affected file lib/silcutil/silcnet.[ch].
415 * If key exchange or rekey protocol is active for a connection
416 parse all packets syncronously since there might be packets
417 in packet queue that we are not able to process without first
418 processing packets before them. Affected file silcd/server,
419 lib/silcclient/client.c.
421 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
422 whether library should continue processing the packet.
423 Affected file lib/silccore/silcpacket.h.
425 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
426 SilcSFTPMonitorData to SFTP server to monitor various
427 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
428 lib/silcsftp/sftp_server.c.
430 * Added silc_file_size to return file size. Affected file
431 lib/silcutil/silcutil.[ch].
433 * Implemented the file transfer support for the client library.
434 Added preliminary support for simple client to client one-file
435 transmission. Affected file lib/silcclient/client_ftp.c,
436 lib/silccilent/client.[ch].
438 * Added new local command FILE to the Irssi SILC Client.
439 It is used to perform the file transfer. It has subcommands
440 SEND, RECEIVE, SHOW and CLOSE. Affected files
441 irssi/src/silc/core/client_ops.c,
442 irssi/src/silc/core/silc-server.[ch].
444 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
446 * Relay the SILC_PACKET_FTP in the server. Affected files
447 silcd/server.c and silcd/packet_receive.c.
449 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
451 * Renamed silc_file_read and silc_file_write to functions
452 silc_file_readfile and silc_file_writefile. Added function
453 silc_file_open and silc_file_close. Affected files
454 lib/silcutil/silcutil.[ch].
456 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Resolve the client info when received private message or
459 channel message for a client which nickname we don't know.
460 Affected files lib/silcclient/client_prvmsg.c and
461 lib/silcclient/client_channel.c.
463 * Do not crash in /KEY if client is not connected. Affected
464 file irssi/src/silc/core/silc-channels.c.
466 * Added SilcClientStatus field to the SilcClientEntry in the
467 lib/silcclient/idlist.h.
469 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
470 is incomplete and is being resolved, it won't be resolved
473 Make sure also that USERS command reply does not resolve
474 twice information. Affected file is
475 lib/silcclient/command_reply.c.
477 Make sure that silc_client_get_clients_by_list does not
478 resolve twice same information.
480 * Check for valid client->id in the silc_server_free_client_data.
481 Affected file silcd/server.c.
483 * Fixed /GETKEY nick@server not to crash if the server entry
484 is not found. Affected file lib/silcclient/command.c.
486 * Fixed the silc_server_check_cmode_rights to check the
487 requested modes correctly. Affected file silcd/command.c.
489 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
491 * Better checks for non-printable chars in nick added.
492 Affected file silcd/command.c.
494 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Call the silc_server_udpate_servers_by_server in the
497 primary router that comes back online in the backup resuming
498 protocol. Otherwise it routes packets wrong. Affected file
499 silcd/server_util.[ch], silcd/server_backup.c.
501 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
503 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
504 lib/silcutil/silcbuffmt.[ch].
506 * Redefined the SILC packet header to include the padding
507 length. Affected file lib/silccore/silcpacket.[ch].
509 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
510 length for maximum padding up to 128 bytes). Affected
511 file lib/silccore/silcpacket.h.
513 * Removed all backwards support for old 0.5.x MAC thingies.
514 The SILC packet header change makes it impossible to be
515 backwards compatible.
517 * Send the ENDING packet with timeout in the backup resuming
518 protocol. This is to assure that all routers has connected
519 to the primary router. Affected file silcd/server_backup.c.
521 * Changed the RNG to take the first IV from random data. It
522 used to take it from zero actually. Changed the RNG also
523 to use /dev/urandom during session. /dev/random is used
524 in initialization. Affected file lib/silccrypt/silcrng.[ch].
526 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
528 * Changed the SILC packet header to have the first two bytes
529 (the packet length) encrypted. Affected files aroung the
530 code tree, lib/silccore/silcpacket.[ch]. Removed the
531 SilcPacketCheckDecrypt callback. It is not needed anymore
532 since the silc_packet_receive_process will determine now
533 whether the packet is normal or special.
535 * Implemented the unidirectional MAC keys. Affected files
536 lib/silcske/silcske.c, silcd/protocol.c and
537 lib/silcclient/protocol.c.
539 * Implemented the packet sequence number to the MAC computation.
540 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
541 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
542 lib/silcclient/protocol.c.
544 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Allow backup router to announce servers. All servers
547 announced by backup router are added to the global list
548 automatically. Update hte server's socket to our primary
549 router also when backup router announces a server.
550 Affected file silcd/packet_receive.c.
552 * Do not update the client->router in the function
553 silc_server_udpate_clients_by_server if the client is on
554 global list. We might fail to find any specific server
555 for locally connected clients and local cell clients. They
556 should still use the `from' and not `to' as client->router.
557 This fixes backup router resuming protocol. Affected file
560 * Decrease channel statistics count only if the channel
561 deletion worked. Affected files are silcd/server.c and
564 * Added silc_server_update_servers_by_server to update origin
565 of all server entries. Used during backup router protocol.
566 Affected files silcd/server_util.[ch], silcd/server.c. and
567 silcd/backup_router.c.
569 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
570 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
571 silc_hmac_get_hash and silc_hmac_get_name. Affected file
572 lib/silccrypt/silchmac.c.
574 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
576 * Assure that router cannot reroute the same channel message
577 to the sender. Affected file silcd/packet_receive.c.
579 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Made better checks that the channel message is not sent
582 to the router it came from. Affected file is
583 silcd/packet_send.c. Fixed memory leak too.
585 * Announce informations for incoming router connection, but
586 only after checking if it is replaced by backup router.
587 Affected file silcd/packet_receive.c.
589 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
591 * Fixed the backup resuming protocol to work in multiple
592 router environment. Affected file silcd/server_backup.c.
594 * Route packet only to one router in the function
595 silc_server_packet_send_to_channel. Affected file is
598 * Fixed silc_server_send_notify_dest to set the broadcast
599 flag. Fixed the silc_server_send_notify_topic to actually
600 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
601 Affected file silcd/packet_send.c.
603 * Changed the SFTP Filesystem interface. Changed the
604 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
605 the filesystem operation function. The SilcSFTPFilesystem
606 is now a context that is allocated by all filesystem allocation
607 functions and it already includes the operations structure
608 and filesystem specific context. It is given as argument
609 now to the silc_sftp_server_start. This made the interface
610 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
611 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
613 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
615 * Changed the backup router adding and getting interfaces
616 in the server. The router that will be replaced by the
617 specified backup router is now sent as argument. Affected
618 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
621 * Added silc_net_addr2bin_ne to return the binary form of
622 the IP address in network byte order. Affected files
623 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
625 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
627 * Check for existing server ID in silc_server_new_server
628 and in silc_server_connect_to_router_final and remove the
629 old entry if it exists. Affected file silcd/packet_receive.c,
632 * Send the channel message always to only one router, either
633 in upstream or downstream. Affected file is
636 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
638 * Wrote the definition of the backup resuming protocol to the
639 protocol specification.
641 * Removed one redundant channel key generation from normal
642 server during joining procedure. Removed one redundant
643 channel key sending from server to router during joining
644 procedure. Affected file silcd/command.c.
646 * Made minor bugfixes to the backup router resuming protocol.
647 Affected file silcd/server_backup.c, server.c.
649 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
651 * Added --disable-asm configuration option. Affected files
652 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
655 * Implemented the backup resuming protocol that is used to
656 resume the primary router position in the cell after the
657 primary router comes back online. Affected files
658 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
659 and silcd/server_util.[ch].
661 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
663 * Sleep two (2) seconds after sending QUIT command to server.
664 Affected file lib/silcclient/command.c.
666 * Assure that if outgoing data buffer is pending do not force
667 send any data. Affected file silcd/packet_send.c.
669 * Assure that if outgoing data buffer is pending do not force
670 send any data. Affected file lib/silcclient/client.c.
672 * Implemented the backup router support when the primary router
673 goes down. The servers and routers can now use the backup
674 router as new primary router without loosing connectivity.
676 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
678 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
679 in the server to indicate disabled entry. All data read
680 from the connection will be ignored and no data is sent
681 for entry that is disabled. Affected files are
682 silcd/idlist.h, silcd/server.c.
684 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Created SFTP client and server test programs in the
687 lib/silcsftp/tests directory.
689 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Implemented memory filesystem (virtual filesystem) for
692 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
695 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Implemented the SFTP (SSH File Transfer Protocol) to the
698 lib/silcsftp. It includes SFTP client and SFTP server
701 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
703 * Moved lib/silccore/silcprotocol.[ch] to the
704 lib/silcutil library.
706 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
707 take variable argument list pointer as argument. Affected
708 file lib/silcutil/silcbuffmt.[ch].
710 * Added silc_buffer_set function that is used to set data
711 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
712 Affected file lib/silcutil/silcbuffer.h.
714 * Changed various routines in the core library to use the new
715 silc_buffer_set instead of allocating new buffer only for
718 * Added 64-bit value formatting and unformatting support to the
719 silc_buffer_[un]format routines. Affected file is
720 lib/silcutil/silcbuffmt.[ch].
722 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
723 to includes/bitmove.h.
725 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
727 * Fixed channel user mode saving in client library. Affected
728 file lib/silcclient/command[_reply].c.
730 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Defined the file transfer to the SILC Protocol. Added
733 new packet type SILC_PACKET_FTP and defined File Transfer
734 Payload. The mandatory file transfer protocol is SFTP
735 (SSH File Transfer Protocol). Affected file in addition
736 of the internet draft is lib/silccore/silcpacket.h.
738 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
739 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
740 is used as part of backup router protocol when the primary
741 router of the cell is back online and wishes to resume
742 the position as primary router.
744 * Redefined the MAC generation keys in the protocol. The
745 same key is not used anymore in both direction. Both
746 direction will now use different keys for sending and
747 receiving. This fixes a potential security flaw. This
748 change causes incompatibilities in the protocol.
750 * Redefined also the MAC computation from the packet.
751 An packet sequence number is now added to the MAC
752 computation. This prevents possible replay attacks against
753 the protocol. This change too causes incompatibilities
756 Added `sequence' field to the SilcPacketContext to hold
757 the current sequence number for the packet.
759 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
761 * Added `created' field to the SilcIDListData in the file
762 silcd/idlist.h to indicate the time when the entry was
765 * Added `created' field to the SilcChannelEntry too. Affected
768 * Added `creation_time' aguments to all the announcement functions
769 in the server. If it is provided then only the entries that
770 was created after the provided time frame are actually
771 announced. Affected file silcd/server.[ch].
773 * The protocol says that the Channel ID's IP address must be
774 based on the router's IP address. Added check for this in
775 the silc_server_new_channel when processing incoming New Channel
776 Payload. Affected file silcd/packet_receive.c.
778 * Print out the correct version with --version in SILC client.
779 Affected file irssi/src/silc/core/silc-core.c.
781 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Fixed WHOWAS command to check for completnes of the client
784 entry always, not just when the command is coming from client.
785 Affected file silcd/command.c.
787 * Added new function silc_server_packet_queue_purge to purge the
788 outgoing data queue to the network. After the function returns
789 it is guaranteed that the outgoing packet queue is empty.
790 Affected file silcd/packet_send.[ch].
792 * Purge the outgoing packet queue in the rekey protocol's final
793 callback to assure that all rekey packets go to the network
794 before quitting the protocol. Affected file silcd/server.c.
796 * Added silc_client_packet_queue_parse as similar function as
797 in server to the client library. The affected file is
798 lib/silcclient/client.c.
800 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
802 * Splitted silcd/server.c and created silcd/server_util.[ch]
803 for utility functions.
805 * Added new socket flag SILC_SF_DISABLED to indicate that the
806 connection is open but nothing can be sent to or received from
807 the connection. Affected file lib/silcutil/silsockconn.[ch].
808 The checking for disabled socket is checked in the low level
809 silc_socket_write and silc_socket_read functions.
811 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Allow only nicknames and channel names that fits into the
814 7-bit unsigned char ASCII set. Affected file silcd/command.c.
816 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
818 * When processing JOIN command reply in server check that if
819 the channel exists in our global list we'll move it the local
820 list. Affected file silcd/command_reply.c.
822 * Fixed the check whether client is joined on the channel already
823 in JOIN command. Affected file lib/silcclient/command.c.
825 * Fixed the JOIN command reply to check whether the channel
826 already exists. Affected file lib/silcclient/command_reply.c.
828 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
830 * Added silc_ske_status_string to map the SKE error numbers
831 to readable strings. The affected files are
832 lib/silcske/silcske[_status].[ch].
834 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Do not show the private channels on the WHOIS channel list
837 as it is not allowed by the protocol. The affected file is
840 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
842 * Assure that the packet length digged from the actual packet
843 is something sensible in the silc_packet_decrypt_rest_special
844 in lib/silccrypt/silcpacket.c.
846 * Free and NULL the allocated pointer in silc_hmac_alloc if
847 the HMAC allocation fails. The affected file is
848 lib/silccrypt/silchmac.c.
850 * Print the selected security properties to the log files in
851 the server. Affected file silcd/protocol.c.
853 * Add SKE's reference counter even if calling the completion
854 callback manually. Otherwise it goes negative, although it
855 does not cause any problems. The affected file is
856 lib/silcske/silcske.c.
858 * Remove the client entry with short timeout after giving the
859 KILL command. Affected file lib/silcclient/command.c.
861 * Fixed to send error reply in WHOIS and IDENTIFY commands in
862 case all found clients are already disconnected (WHOWAS would
863 found them) in the server. Affected file silcd/command.c.
865 * Update the last_receive (time of last data received) to be
866 updated only when received private or channel message so that
867 the idle time showed in WHOIS makes more sense.
869 * Added boolean field `valid' in to the SilcClientEntry in the
870 client library to indicate whether the entry is valid or not.
871 This fixes the nickname change bug on channel when changing
872 the nickname to be same than the old (like nick to Nick) the
873 nickname formatter doesn't set the new nick anymore to Nick@host.
874 Affected file lib/silcclient/idlist.[ch].
876 * Now actually fixed the nickname changing on disconnection.
877 Added new function silc_change_nick to the Irssi SILC Client.
878 Affected file irssi/src/silc/core/client_ops.c,
879 irssi/src/silc/core/silc-nicklist.[ch].
881 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Check that the public key exists in the GETKEY command before
884 trying to encode it. Affected file silcd/command.c.
886 * Print some notifications on received public keys with GETKEY
887 command in the Irssi SILC Client. Affected files are
888 irssi/src/fe-common/silc/module-formats.[ch],
889 irssi/src/silc/core/client_ops.c.
891 * Use IDENTIFY command to resolve the server information in the
892 GETKEY command instead of INFO command. Affected file
893 lib/silcclient/command.c.
895 * All command reply functions in the client library now calls
896 the pending command reply callbacks even if an error has
897 occurred. The server has done this a long time and now it was
898 time to move the client library to this as well. Now all
899 errors can be delivered back to the pending command reply
900 callbacks if necessary. Affected files are
901 lib/silcclient/command[_reply].[ch].
903 * Change the nickname on disconnection back to the username
904 because in reconnect the server will enforce it to it anyway.
905 Affected file irssi/src/silc/core/silc-servers.c.
907 * Fixed a config file parsing bug in the Irssi SILC client.
908 Affected file irssi/src/silc/core/clientconfig.c.
910 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
912 * When printing the channel mode on JOIN, verify that the
913 channel key and channel's HMAC are valid. Affected file
914 irssi/src/silc/core/client_ops.c.
916 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
919 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
920 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
922 * Removed channel key rekey task deleting from the function
923 silc_server_save_channel_key. Affected file silcd/server.c.
924 Added explicit timeout task context instead that is used to
925 delete the task if we are registering a new task before the
926 new task has elapsed.
928 * When channel key rekey occurs the client library now saves
929 the old channel key for a short period of time (10 seconds) and
930 is able to use it in case some is still sending channel
931 messages encrypted with the old key after the rekey. Affected
932 file lib/silcclient/[idlist.h|client_channel.c].
934 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Added check to the silc_server_new_id_real to not accept
937 new ID if it is the sender's own ID. Affected file is
938 silcd/packet_receive.c.
940 * Assure that we do not announce ourself or the one we've
941 sending our announcements when we're router and are announcing
942 servers to our primary router. Affected file silcd/server.c.
944 * Fixed silc_server_command_identify_check_client to assemble
945 correct WHOIS packet. It send corrupted WHOIS packet and
946 caused problem with router to router connections. Affected
947 file silcd/command.c.
949 Fixed also silc_server_command_whois_check the same way
950 as for the IDENTIFY command.
952 * Added new SilcIDListStatus to the server in the SilcIDListData
953 structure. The status now includes the current status of
954 the entry (like registered, resolved etc.). Affected file
955 silcd/idlist.[ch]. Defined a bunch of different status types
956 as well. This replaced the old boolean registered field as well.
958 Added resolve_cmd_ident field to the SilcClientEntry structure
959 too so that if the entry is for example being resolved so
960 another command may attach to the same pending command reply
961 without requiring to resolve the same entry again. This concept
962 should optimize the WHOIS and the IDENTIFY resolving under
963 heavy load by taking away unnecessary resolving for entries
964 that are being resolved already.
966 Added support for adding multiple pending commands for one
967 command idenfier. Affected file silcd/command[_reply].[ch].
969 * Fixed WHOIS and IDENTIFY save to remove the cache entry
970 before deleting the data. Otherwise the hash table will have
971 freed data in comparison functions. Affected file is
972 silcd/command_reply.c.
974 * Fixed silc_idlist_replace_client_id to add the new entry to
975 the cache with NULL nickname. Otherwise there will be invalid
976 memory as the nickname after the nickname is freed. Affected
977 file silcd/packet_receive.c.
979 * Fixed the silc_idlist_get_clients_by_hash. The entries was
980 saved into wrong slots because the previous number of entries
981 was not taken into account. Affected file silcd/idlist.c.
982 Fixed same thing in silc_idlist_get_clients_by_nickname too.
984 * If we are router and we receive JOIN notify to a channel that
985 does not have any users then notified client is marked as the
986 channel founder, as it is it. The affected file is
987 silcd/packet_receive.c
989 * Added to the extended hash table API's table_del_*ext functions
990 the destructor as argument too, so that the caller can decide
991 which destructor to use or whether to use destructor at all.
992 Affected file lib/silcutil/silchashtable.[ch].
994 * Fixed ID Cache purging. It actually deleted the entries from
995 the hash table after the data was freed. The hash table ended
996 up comparing freed memory. The affected file is
997 lib/silccore/silcidcache.c.
999 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Fixed Irssi SILC client's KILL command's HELP syntax.
1003 * The USERS command now resolves the detailed user information
1004 if the userinfo field is missing. Affected file is
1005 lib/silcclient/command_reply.c.
1007 * Do not print error in silc_file_read if the read file does
1008 not exist. Just silently return NULL. Affected file is
1009 lib/silcutil/silcutil.c.
1011 * Fixed the silc_log_output to not wine about NULL filename
1012 and to not create some bogus " " filename. Affected file is
1013 lib/silcutil/silclog.c.
1015 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Fixed various printing bugs on the user interface in the
1018 Irssi SILC Client. Minor changes that were forgotten from
1021 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1023 * Fixed the configure.in.pre and the compilation and distribution
1024 environment to support the new autoconf 2.52. That version is
1025 now required to compile the CVS trunk.
1027 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1030 to generally parse user@fqdn format strings. Affected file
1031 lib/silcutil/silcutil.c.
1033 * Added nickname_format and nickname_force_format fields to the
1034 SilcClientParams structure. The first one defines the format
1035 for the nicknames that the library will enforce if the receives
1036 multiple same nicknames. The second one is boolean value and
1037 can be used to force the library to always enforce the format
1038 to the nicknames regardles whether there are multiple nicknames
1039 or not. This configurable formatting was employed to flexibly
1040 support accessing multiple nicknames from the user interface.
1041 The userinterface can now set the nicknames to what ever format
1042 they prefer. Affected file lib/silcclient/silcapi.h.
1044 Added function silc_client_nickname_format to the file
1045 lib/silcclient/idlist.c. It performs the nickname formatting.
1047 Added new field `hostname´ to the SilcClientEntry context.
1048 It holds the hostname of the client. Affected file is
1049 lib/silcclient/idlist.h.
1051 * Irssi SILC Client sets the nicknames in nick@hostn format.
1052 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1053 irssi/src/silc/core/silc-core.c.
1055 The WHOIS printing now also shows both the real nickname and
1056 the formatted nickname so that user knows how to access the
1057 user if there are multiple same nicknames cached. Affected
1058 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1059 printing formatting too to take the hostname now as a separate
1060 argument. The Affected file is
1061 irssi/src/fe-common/silc/modules-formats.[ch].
1063 * Changed the silc_client_get_clients_local to accept the formatted
1064 nickname as argument. It accepts the real nickname too but the
1065 formatted nickname can be used to find the true entry from
1066 multiple entries. Affected file lib/silcclient/silcapi.h and
1067 lib/silcclient/idlist.c.
1069 * Added nickname_format_parse field to the SilcClientParams.
1070 It is a callback function provided by the application to parse
1071 the nickname out of the formatted nickname string. The library
1072 calls it to get the nickname from the formatted string. Since
1073 the application generally knows better the format of the nickname
1074 string it parses it instead of the library, even though library
1075 encodes the formatted string. If the callback function is not
1076 provided then the library will use the string as is. The
1077 affected file is lib/silcclient/silcapi.h.
1079 * All the nickname strings passed to the client library in
1080 commands are now expected to be formatted nickname strings.
1081 If the command does not support the formatted nickname string
1082 it will assume that the sent string is the actual nickname.
1083 Affected file lib/silcclient/command.c.
1085 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Added public key authentication support to OPER and SILCOPER
1088 commands in the client library. Affected file is
1089 lib/silcclient/command.c.
1091 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Changed the get_auth_methdod client operation to be asynchronous.
1094 It can be async if the application resolves the authentication
1095 method from the server during the negotiation. Added new
1096 SilcGetAuthMeth completion callback that the application will
1097 call after resolving the authentication method.
1099 Added function silc_client_request_authentication_method that
1100 the application can use to resolve the authentication method
1101 from the server. Added also SilcConnectionAuthRequest callback
1102 that the library will call after the server has replied. The
1103 application can call this function if it does not know the
1104 current authentication method.
1106 Affected files are lib/silcclient/client.c and
1107 lib/silcclient/silcapi.h.
1109 * The Irssi SILC client now automatically resolves the authentication
1110 method incase any configuration information is not present (and
1111 currently there never is). The affected file is
1112 irssi/src/silc/core/client_ops.c.
1114 * Fixed public key authentication from the client library.
1115 Affected file lib/silcclient/protocol.c. Changed also the
1116 protocol specification about the public key authentication in
1117 the connection authentication protocol. The actual data to be
1118 signed is now computed with a hash function before signing.
1120 * Fixed the public key authentication from the server as well.
1121 Affected file silcd/protocol.c.
1123 * Removed the mlock()'s from the memory allocation routines.
1124 Affected file lib/silcutil/silcmemory.c. The ./configure does
1125 not check anymore for the mlock(). Affected file is
1128 * Fixed USERS command in server to allow the execution of the
1129 command for private and secret channels if the client sending
1130 the command is on the channel. Affected file silcd/command.c.
1132 * Fixed silc_client_get_clients_local to return the clients
1133 count correctly. It could return wrong value. Affected file
1134 lib/silcclient/idlist.c.
1136 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1139 types. The assembler optimizations seemed not to like 64-bit
1140 data types. The assmebler optimizations thus are now enabled
1141 also for BSD systems as opposed to only enable them for Linux.
1143 * Do not check for threads at all on BSD systems. Affected
1144 file configure.in.pre.
1146 * Removed -n and -h options from the Irssi SILC Client since
1147 they are not used in silc.
1149 * Fixed the prime generation to assure that the first digit
1150 of the generated random number is not zero since our conversion
1151 routines does not like number strings that starts with zero
1152 digit. If zero digit is seen the random number is regenerated.
1153 This caused some corrupted RSA keys when the zero first digit
1154 was met. Affected file lib/silcmath/silcprimegen.c.
1156 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Fixed WIN32 configuration in the ./configure script.
1159 Fixed to include xti.h on environments that has it.
1160 Patches by Carsten Ilchmann and andrew.
1162 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1164 * Changed the silc_id_create_client_id to be collision
1165 resistant. It is now assured that there cannot be created
1166 two same client ID's. I suspect that some weird bugs in
1167 the server were actually caused by duplicate Client IDs.
1168 Affected file silcd/serverid.[ch]. A router receiving
1169 new ID now also assures and informs the sending server
1170 if the ID caused collision.
1172 * Changed the silc_id_create_channel_id to also assure that
1173 there are no collisions.
1175 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * Statement about ignoring the Mutual Authentication flag when
1178 performing rekey with PFS was a bit misleading. It is ignored
1179 if it was set in the initial negotiation, it cannot be even
1180 set in the rekey. Fixed in the ke-auth draft. Started the
1181 new versions of the protocol drafts in the doc/.
1183 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed a bug in silc_client_command_identify_save when saving
1186 new channel information. The channel name was no duplicated
1187 and caused crash on exit. Affected file is
1188 lib/silcclient/command_reply.c.
1190 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed the getkey command handling in the server. Send just
1193 empty OK reply to the sender if the key could not be fetched
1194 (but everything else was ok, like the key just was not available).
1195 Changed the public key parameter to optional in the protocol
1196 specs so that empty OK reply can be sent. Affected file
1199 Added a message to Irssi SILC client to tell to user if the
1200 server did not return a public key.
1202 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Fixed a channel key regeneration bug. It registered new
1205 timeout tasks exponentially until all system resources were
1206 used. Affected file silcd/server.c.
1208 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Added the SILC Document generator to the scripts/silcdoc.
1211 It can be used to generate the Toolkit Reference Manual out
1212 of the source tree. Internally it will also use the RoboDoc
1213 generator now imported in util/robodoc.
1215 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Added couple of return's in rekey protocol if error orccurred
1218 during the protocol. The execution must be terminated.
1219 Affected file silcd/protocol.c. Also, terminate the protocol
1220 always with timeout.
1222 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * The client's Client ID was created initally from the wrong
1225 nickname (it could have been in format nick@host) in the
1226 silc_server_new_client. Affected file silcd/packet_receive.c
1228 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Added some SILC_LOG_ERROR's to various error conditions
1231 if client could not be added to ID cache. Affected files
1232 silcd/packet_receive.c and silcd/server.c.
1234 * When client's sock->user_data is freed, NULL also the
1235 client->router and client->connection pointers. Added check
1236 for these pointers being NULL to various places around the
1237 code. Affected file silcd/server.c.
1239 * Added client->data.registered == TRUE checks to various
1240 places around the code to assure that unregistered client's
1241 are not handled when it is not allowed. Affected file
1244 * Added `bool registered' fields to all
1245 silc_idlist_[server|client]_get_* routines to indicate whether
1246 the fetched client needs to be registered or not. Affected
1247 file silcd/idlist.[ch].
1249 * Add your own entry as registered to the ID cache in the
1250 server. Affected file server.c.
1252 * Fixed a bug in silc_server_new_server. The SilcServer was
1253 set as the new server's context instead of SilcServerEntry.
1254 This naturally caused some weird bugs.
1256 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Do not delete the channel rekey task when adding it
1259 for in silc_server_create_channel_key.
1261 * Changed the silc_server_create_channel_key to return
1262 TRUE or FALSE to indicate the success of the channel key
1265 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Fixed MSVC++ project files and added missing files to
1268 Makefiles under win32/.
1270 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Do not add TCP_NODELAY flag if the operating system
1273 does not have it defined. Affected files are
1274 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1276 * Fixed buffer overflow from Irssi SILC Client. Affected
1277 file irssi/src/fe-common/core/themes.c.
1279 * Fixed double free in client library in the file
1280 lib/silcclient/client.c when disconnecting from server.
1282 * Applied double free patch from cras to Irssi SILC client.
1283 Affected files irssi/src/core/[modules/expandos].c
1285 * Fixed the disconnection handling to Irssi SILC Client.
1286 The application must call silc_client_close_connection
1287 in ops->connect client operation in case of failure of
1288 the connection. Affected file is
1289 irssi/src/silc/core/client_ops.c.
1291 * Do not set sock->protocol to NULL in the function
1292 silc_client_close_connection after executing the protocol's
1293 final callback since the sock might not be valid anymore.
1294 Affected file lib/silcclient/client.c.
1296 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Do not enable SILC_THREADS if the linking with libpthread
1299 did not happen. Affected file configure.in.pre.
1301 * Added notion to protocol specification that server must
1302 verify the sent authentication payload with CMODE when
1303 setting the channel founder key. Implemented it to the
1304 server. Affected file silcd/command.c.
1306 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * Added _EXTRA_DIST SILC distribution variable to the
1309 distributions file. It is used to conditionally add extra
1310 files or directories to the specific distribution. Affected
1311 files ./prepare, Makefile.am.pre and distributions.
1313 Removed the `_' from the start of the distribution names.
1316 * Added README.WIN32 for instructions to compile the Toolkit
1319 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Fixed a double free in disconnection in the server. Affected
1322 file is silcd/server.c.
1324 * Fixed the lib/silcske/groups.c to work now also with GMP
1325 MP library. The string conversion did not work when using
1326 specific base and the base is indicated in the string as well.
1328 * Created win32/ directory which now includes MSVC++ specific
1329 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1330 It will appear only in the toolkit distribution
1332 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Changed the key material distribution function in case when
1335 the hash output is too short. The data is now concatenated
1336 a bit differently than it used to. Made the change to the
1337 SKE protocol specification.
1339 * Added better GMP detection to configure.in.pre. A patch
1342 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Fixed a minor bug in SKE that might cause some problem on
1345 some platforms. Affected file lib/silcske/silcske.c.
1347 * Added the cookie checking for initiator in the SKE. It checks
1348 that the responder returns the sent cookie unmodified. The
1349 affected file is lib/silcske/silcske.c. Added new SKE
1350 error type INVALID_COOKIE that can be sent during the
1351 negotiation. Fixed some memory leaks as well.
1353 * Added the "invalid cookie" error message to Irssi SILC client's
1356 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Added `task_max' field to the SilcClientParams to indicate
1359 the maximum tasks the scheduler can handle. If set to zero,
1360 default values are used. Affected file lib/silcclient/silcapi.h.
1362 * Fixed memory leaks in silc_client_close_connection. Affected
1363 file lib/silcclient/client.c.
1365 * Added silc_client_del_client_entry to client library to free
1366 all memory of given client entry. Affected file is
1367 lib/silcclient/idlist.[ch].
1369 * Added new functions silc_client_del_channel and
1370 silc_client_del_server to delete channel and server entries.
1371 Affected file lib/silcclient/[silcapi.h/idlist.c].
1373 * Removed silc_client_del_client_by_id from silcapi.h.
1375 * Fixed the INFO command to return the server's own info
1376 correctly when querying by Server ID. Affected file is
1379 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Removed the non-blocking settings in WIN32 code in the
1382 silc_sock_[read/write] and added SleepEx instead. Affected
1383 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1384 of input data is now checked with FIONREAD and ioctlsocket.
1386 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Call silc_schedule_task_del_by_context in the
1389 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1390 Affected file lib/silccore/silcprotocol.c.
1392 * Call silc_protocol_cancel for active protocols in the
1393 silc_server_close_connection if the funtion
1394 silc_server_free_sock_user_data has not been called.
1395 Affected file silcd/server.c.
1397 * Generic tasks cannot be deleted using the del_by_fd
1398 task deleting function since generic tasks does not match
1399 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1401 * Added a notion to SILCOPER help file that the SILCOPER works
1402 only on router server, not on normal server.
1404 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Added for WIN32 support for the new scheduler as well.
1407 Affected file lib/silcutil/win32/silcwin32schedule.c.
1409 * Fixed the SHA1 implementation to work on various platforms.
1411 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1414 API. It is part of the scheduler now. Everything else is
1415 as previously but some functions has changed their names.
1416 Checkout the lib/silcutil/silcschedule.h for the interface.
1417 Updated all applications to use the new interface. Affected
1418 files are lib/silcutil/silcschedule.[ch].
1420 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Found a bug in the SKE implementation. The HASH value,
1423 specified by the protocol, was not computed correctly. The
1424 public key of the responder was not added to the computation
1425 even though it is mandatory. Affected file lib/silcske/silcske.c.
1426 This unfortunately causes incompatibilities with older
1427 clients and servers.
1429 * Added WIN32 specific network init and uninit functions:
1430 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1431 the Winsock2. Affected file lib/silcutil/silcnet.h and
1432 lib/silcutil/win32/silcwin32net.c.
1434 * Set the socket always to nonblocking mode on WIN32 after
1435 reading data or writing data. Affected file is
1436 lib/silcutil/win32/silcwin32sockconn.c.
1438 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Fixed various compilation problems under WIN32. Affected
1441 files lib/silcutil/win32/silcwin32thread.c and
1442 lib/silcutil/win32/silcwin32schedule.c.
1444 * Removed all _internal.h #includes from public header
1445 files. Internal headers must never be included from
1448 Removed also the lib/silcske/payload_internal.h file.
1450 * All include files that may be needed (public and some others
1451 included by the public headers) by application developers are
1452 now copied to the ./includes directory. It does not copy any
1453 internal headers. Affected file Makefile.defines.pre and all
1454 Makefile.am's under lib/ and subdirs.
1456 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Do not change the ~/.silc directory's permissions automatically.
1459 Affected file irssi/src/silc/core/clientutil.c.
1461 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Do not cancel the protocol in silc_server_close_connection
1464 it might cause recursion. Now cancelled in the function
1465 silc_server_free_sock_user_data. Affected file silcd/server.c.
1467 * Fixed the silc_server_remove_clients_by_server to regenerate
1468 the channel keys correctly finally. Added also new function
1469 silc_server_remove_clients_channels to actually do it.
1470 Affected file silcd/server.c.
1472 * Fixed the silc_server_new_channel to not crash by giving
1473 wrong router to the new channel. Affected file is
1474 silcd/packet_receive.c.
1476 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1479 which is given as argument to the silc_client_alloc now.
1480 It can be used to configure the client and set various parameters
1481 that affect the function of the client.
1483 * The USERS command in server did not check whether the channel
1484 is private or secret. Affected file silcd/command.c.
1486 * Added new argument to the USERS command in protocol specification.
1487 The USERS command now can take the channel name as argument
1488 as well. Added support for this in client and server and
1489 updated the protocol specs.
1491 * Completed the GETKEY command in client. It can be now used
1492 to fetch also servers public key not only some clients.
1493 Affected files lib/silcclient/command[_reply].c.
1495 * Added silc_client_get_server to return server entry by the
1496 server name. Affected files lib/silcclient/silcapi.h and
1499 * Redefined the IDENTIFY command in protocol specification to be
1500 more generic. It now can be used to query information about
1501 any entity in the SILC Network, including clients, servers and
1502 channels. The query may be based either the entity's name
1503 or the ID. Added support for this in both client and server.
1505 Affected files silcd/command.c and lib/silcclient/command.c
1506 and command_reply.c.
1508 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1509 the _from_client and _from_server functions. Affected file
1512 * Added silc_client_get_channel_by_id_resolve to the file
1513 lib/silcclient/silcapi.h to resolve channel information by
1514 its ID. Added also silc_client_get_channel_by_id that
1515 does not resolve it from the server.
1517 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Added SilcServerEntry context into the client library
1520 to represent one server. The INFO command now allocates
1521 these to save the resolved server info. For now on the
1522 client library will also keep information about servers,
1523 connected and resolved with INFO.
1525 The INFO command now allocates the SilcServerEntry context
1526 and saves the server info there. The COMMAND_REPLY in
1527 the INFO now returns the parameters to application in
1528 same order as defined in the protocol specification.
1530 The entries are cached in the client->server_cache.
1532 * The INFO command is now issued after received the Client ID
1533 from the server. Affected file lib/silcclient/client.c.
1535 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1536 to the application as the mode changer might be server.
1537 It is guaranteed that NULL is not returned anymore to the
1538 application. Affected file lib/silcclient/client_notify.c.
1540 The ID Type is now also passed to the application so that
1541 it can check whether the returned entry is SilcClientEntry
1544 Added new function silc_client_get_server_by_id to return
1545 the server entry by ID. Affected files are the
1546 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1548 * Do not create the channel in the Irssi SILC Client when issuing
1549 the JOIN command but when received the sucessful JOIN command
1550 reply. Otherwise the channel might get created even though we
1551 could not join it. The Affected file is
1552 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1554 * Fixed a channel joining bug in router. The router must also
1555 check the channel modes, invite and ban lists etc. when serving
1556 the JOIN command sent by normal server. Affected file is
1557 silcd/command.c. The router now resolves the client's
1558 information from the server who sent the JOIN command if it
1559 does not know it, and processes the JOIN command only after
1562 * Changed the SilcCommandCb to take new argument; void *context2.
1563 Affected file lib/silccore/silccommand.h
1565 The second argument in the command callbacks in the server now
1566 includes the SilcServerCommandReplyContext if the command was
1567 called as pending command callback from the command reply.
1568 Otherwise it is NULL. When called as pending the status of the
1569 command reply will be checked and if it was erronous the
1570 error will be sent to the original sender of the command.
1571 This way the client always receives the error messages even
1572 though the server was actually the one who received the error
1573 when it resent the command to router, for example. Affected
1574 files silcd/command[_reply].[ch].
1576 * Fixed sending WHOWAS command's error message to client if
1577 the requested client could not be found. It was missing.
1580 * Changed the CMODE and CUMODE commands reply arguments in the
1581 protocol specification. The Channel ID is now sent in both
1582 of the commands to identify the channel. Implemented this
1583 new feature to the client and server. Affected files
1584 lib/silcclient/command_reply.c and silcd/command.c.
1586 * Made better checks for invite and ban lists in the JOIN
1587 command in server. Affected file silcd/command.c.
1589 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * The server now performs the incoming host IP/DNS lookup
1592 using the silc_socket_host_lookup and thus does not block
1593 the server anymore. Affected file silcd/server.c.
1595 * Completed the multi-thread support for SILC Scheduler in
1596 the lib/silcutil/silcschedule.c.
1598 * Fixed the configure.in.pre to detect the pthread correctly
1601 * Fixed a deadlock in silc_task_queue_wakeup in the file
1602 lib/silcutil/silctask.c.
1604 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Added new function silc_schedule_wakeup that is used in
1607 multi-threaded environment to wakeup the main thread's
1608 schduler. It needs to be used when a thread adds a new task
1609 or removes a task from task queues. After waking up, the
1610 scheduler will detect the task queue changes. If threads
1611 support is not compiled in this function has no effect.
1612 Implemented the wakeup mechanism to both Unix and WIN32
1613 systems. Affected files are lib/silcutil/silcschedule.[ch],
1614 lib/silcutil/unix/silcunixschedule.c and the
1615 lib/silcutil/win32/silcwin32schedule.c.
1617 * Added new function silc_task_queue_wakeup to wakeup the
1618 scheduler by the specified task queue. Affected file
1619 lib/silcutil/silctask.[ch].
1621 * The silc_socket_host_lookup_start now wakes up the scheduler
1622 after adding the timeout task. Affected file is
1623 lib/silcutil/silcsockconn.c.
1625 * The silc_socket_host_lookup is synchronous now if the threads
1626 support is not compiled in. However, the callback is still
1627 called asyncronously through the scheduler, anyway. Affected
1628 file lib/silcutil/silcsockconn.c.
1630 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Added new function silc_socket_host_lookup to perform
1633 asynchronous IP and FQDN lookups for the socket connection.
1634 Affected files lib/silcutil/silcsockconn.[ch].
1636 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1639 that may or may not compile the mutex support in.
1641 Changed the silc_mutex_alloc interface. It allocates the
1642 mutex now to the sent pointer and returns TRUE or FALSE.
1644 Affected file lib/silcutil/silcmutex.h.
1646 * Wrote the SILC Task Queue interface to support multi-threads.
1647 Affected file lib/silcutil/silctask.[ch].
1649 * Wrote the SILC Scheduler to support multi-threads. Affected
1650 file lib/silcutil/silcschedule.c.
1652 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1655 in lib/silcutil/win32/.
1657 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Defined SILC Mutex API and SILC Thread API and implemented
1660 them for Unix. Affected files are
1661 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1662 lib/silcutil/unix/silcunixmutex.c and
1663 lib/silcutil/unix/silcunixthread.c.
1665 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Fixed the silc_server_remove_clients_by_server's channel
1668 key re-generation. The hash table handling was incorrect
1669 and would not work with many channels. Affected file is
1672 * Fixed some memory leaks around the server code.
1674 * Rewrote the silc_server_get_users_on_channel to support IPv6
1675 based Client ID's. Affected file silcd/server.c.
1677 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1678 specification. However, a separate document must be written
1679 to define the detailed signing procedure and the payload
1680 associated with the flag. Defined the flag to the
1681 lib/silccore/silcchannel.h as well.
1683 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Changed the dynamic tables to static size tables in the
1686 lib/silccrypt/silchmac.c.
1688 * Removed GCC dependencies from the code. A patch by cras.
1690 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Do not show the error "Error receiving packet bla bla"
1693 in server if it really was not an error (-2 means that reading
1694 is pending). Affected file silcd/server.c.
1696 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Fixed a possible crash in silc_server_remove_clients_by_server
1699 in silcd/server.c. Fixed there also some memory leaks.
1701 * Fixed the silc_idlist_replace_client_id. It could replace
1702 wrong key in the hash table. Affected file silcd/idlist.c.
1704 * Do not check whether there are global users on the channel
1705 if the channel->global_users is FALSE. Affected functions
1706 silc_server_remove_from_one_channel and
1707 silc_server_remove_from_channels in silcd/server.c. Also,
1708 do not check if the removed client is local as we can be
1709 sure that global client was not removed from the channel
1710 and checking for global users is not needed.
1712 * The silc_server_remove_clients_by_server now re-generates
1713 the channel keys correctly for those channels that had
1714 clients removed from them. Affected file silcd/server.c.
1716 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Found the reason of random crashes in the server. We weren't
1719 ignoring the SIGPIPE signal (which can be sent in write())
1720 and it crashed the server. Affected file silcd/silcd.c.
1722 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Assure that sock->user_data is not NULL in the function
1725 silc_server_packet_send in silcd/packet_send.c.
1727 * Disconnect the remote connection if it could not be added
1728 to any ID lists in the server. The affected file is
1731 * Check in silc_server_packet_send[_real/dest] that the
1732 socket is not disconnecting and ignore the data if it is.
1733 Affected file silcd/packet_send.c.
1735 * Define inline to __inline on native WIN32 compilation.
1736 Affected file includes/silcwin32.h.
1738 * Added some explicit type casts for inline code since MSVC
1739 require them. Affected files lib/silcutil/silcbuffer.h,
1740 lib/trq/silcdlist.h and lib/trq/silclist.h.
1742 * Print warning in log files from now on if the packet
1743 decryption fails. Affected file silcd/server.c.
1745 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Changed the `say' client operation's interface to accept
1748 new `type' argument to indicate the type of the message sent
1749 by the library. The application may filter the library's
1750 messages according the type. The affected file is the
1751 lib/silcclient/silcapi.h.
1753 * Added two new functions to lib/silcclient/silcapi.h:
1754 silc_client_del_client and silc_client_del_client_by_id.
1755 Affected file lib/silcclient/idlist.c.
1757 * Moved the clientincludes.h from includes/ to silc/ and
1758 serverincludes.h from includes/ to silcd/.
1760 * The modes for the CMODE and CUMODE are now passed as
1761 uint32 for application with COMMAND_REPLY. The affected
1762 file is lib/silcclient/command_reply.c.
1764 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * /WHOIS without arguments shows client's own information.
1767 Affected file lib/silcclient/command.c.
1769 * Changed PING to not accept any arguments. The specs
1770 says that client can ping only the connected server so
1771 requiring an argument is not needed. Affected file is
1772 lib/silcclient/command.c.
1774 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Fixed a fatal bug in private message sending and reception
1777 encryption and decryption when using private message keys.
1778 The implementation was incorrect and did not follow the
1779 specification. It causd that some of the message were
1780 lost since it did not use the sending and receiving keys
1781 as the protocol suggests. This has been fixed and will cause
1782 incompatibilities with older clients when sending private
1783 message encrypted with private message keys. Affected files
1784 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1785 and various other in Irssi SILC Client.
1787 Added `responder' boolean argument to the functions
1788 silc_client_add_private_message_key[_ske] to indicate when
1789 the key is added as responder or initiator of the key
1792 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1794 * Removed the silc_ske_check_version function and created
1795 a SilcSKECheckVersion callback. Added also a function
1796 silc_ske_set_callbacks that is now used to set all SKE
1797 callbacks. The callback functions are not given to
1798 the SKE functions anymore, but this function is used to
1801 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1803 * Added `silc_version' argument to the silc_client_alloc
1804 to define the version of the application for the library.
1805 The library will use the version string to compare it
1806 against the remote host's (usually a server) version
1807 string. Affected file lib/silcclient/silcapi.h
1809 * Added the KE protocol context to Key Agreement context
1810 in client library so that we can abort the SKE if it
1811 is in process when we get timeout. Affected file is
1812 lib/silcclient/client_keyagr.c.
1814 * Do not resolve the client ID forever if it returns in the
1815 first time that such client does not exist. This was done
1816 for example with private message. Affected file is
1817 lib/silcclient/client_prvmsg.c.
1819 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * Do not add regex.h for WIN32. The affected file
1822 includes/silcincludes.h.
1824 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1825 not work yet 100%. It generates the DLL's automatically
1826 when compiling with --with-win32 under cygwin.
1828 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * lib/contrib/regex.c is not compiled on WIN32.
1832 * Added silc_net_get_socket_opt function to the
1833 lib/silcutil/silcnet.h.
1835 * Added includes/silcwin32.h for WIN32 specific includes
1838 * Do not use ptime structure or any of the posix process
1839 functions on WIN32 in lib/silccrypt/silrng.c.
1841 * Added silc_gettimeofday to provide generic function
1842 for struct timeval on all platforms. Added the function
1843 to lib/silcutil/silcutil.h.
1845 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1848 library as they clearly belong there. As a plus side we
1849 can make the actual socket connection routines platform
1852 Added also new generic function silc_socket_read and
1853 silc_socket_write (that used to be silc_packet_[read/write].
1854 The implementation of these are platform specific.
1856 * Added WIN32 specific routines of silc_socket_[read/write]
1857 to lib/silcutil/win32/silcwin32sockconn.c.
1859 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Added preliminary support for native WIN32 compilation under
1862 cygwin (using the -mno-cygwin option for GCC) to the
1863 ./configure.in.pre. The --with-win32 now prepares the
1864 compilation for native WIN32.
1866 * Rewrote the SILC Scheduler interface in the file
1867 lib/silcutil/silcschedule.h. The scheduler is now context
1868 based and does not have anymore any global static scheduler.
1869 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1870 and created lib/silcutil/win32 directory for WIN32 based
1873 * Added Unix specific network routines to the
1874 lib/silcutil/unix/silcunixnet.c and the old
1875 lib/silcutil/silcnet.c includes now only generic routines.
1877 Added WIN32 specific network routines to the
1878 lib/silcutil/win32/silcwin32net.c.
1880 * Added Unix specific utility functions from the
1881 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1883 * Added WIN32 SILC Scheduler to the file
1884 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1887 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * Do not handle JOIN notify in the server if the target client
1890 is not registered (idata->registered == FALSE). The affected
1891 file is silcd/packet_receive.c.
1893 * Update the nickrec->founder in event_cumode in the Irssi SILC
1894 client. Affected file irssi/src/silc/core/silc-channels.c.
1896 * Fixed the CUMODE_CHANGE notify handling in the server when
1897 server and router are announcing their clients on channels.
1898 Now the mode changes are saved and notified correctly. The
1899 affected file is /silcd/packet_receive.c.
1901 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1902 They really did not replace the cache entry in the ID Cache.
1903 Now they do that. Affected file silcd/idlist.c.
1905 * Fixed the KICK notify handling in the Irssi SILC client to
1906 update the channel records so that the kicked client does not
1907 appear to be on the channel. The affected file is
1908 irssi/src/silc/core/silc-channels.c.
1910 * Always update the conn->current_channel when executing command
1911 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1913 * Fixed the KILL notify handling in Irssi SILC client to remove
1914 the killed client on all channels.
1916 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Fixed the silc_parse_command_line to remove extra spaces
1919 from the start and end of the arguments. Affected file is
1920 lib/silcutil/silcutil.c.
1922 * Cancel and free any active protocol in the function
1923 silc_server_close_connection. Affected file silcd/server.c.
1925 * Cancel and free any active protocol in the function
1926 silc_client_close_connction. Affected file is
1927 lib/silcclient/client.c.
1929 * Do not execute the KILL command for clients that are in
1930 history (ie. they are not in the network). Affected file is
1933 * Fixed KILL notify handling, client does not crash anymore.
1934 Affected file irssi/src/silc/core/silc-channels.c.
1936 * Reduced the default packet buffer size from 2048 to 1024 in
1937 lib/silccore/silcpacket.c.
1939 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1940 counter to the SKE context that is incresed when the SKE library
1941 performs async operation outside the library. If the outside
1942 process frees the SKE context and FREED status will be set
1943 and the library will detect after the sync operation that the
1944 libary is freed. The affected files are
1945 lib/silcske/silcske[_status].[ch].
1947 * Resolve the client entry information in the function
1948 silc_client_channel_message to assure that NULL pointer is not
1949 passed as client entry to the application. */
1951 * Fixed the task timeout calculation to assure that there is
1952 never negative timeouts. The affected file is
1953 lib/silcutil/silcschedule.c.
1955 * Fixed the channel user mode notification sending in server.
1956 It was sent point-to-point to the router (or to server by router)
1957 but it needs to be destined to a channel. The routines now
1958 supports sending the channel user mode notifys to the channels
1959 when announcing clients and channels. Affected files are
1960 silcd/server.c and silcd/packet_receive.c.
1962 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1963 It did not actually replace the old channel entry in the cache.
1964 Affected file lib/silcclient/client_notify.c.
1966 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Fixed a possible crash in silc_packet_send_prepare. It now
1969 assures always that there is enough space in the buffer and
1970 at the tail area of the buffer (for MAC).
1972 Fixed the inbound buffer reallocation in silc_packet_read.
1973 It was old code and did not handle the reallocation correctly.
1976 The affected file is lib/silccore/silcpacket.c.
1978 * Fixed buffer overflow in silc_parse_nickname in the file
1979 lib/silcutil/silcutil.c.
1981 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * make install generates new server keys only if there is not
1986 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1989 Added check that if the NOREPLY is set then we will not send
1990 the away message. This avoids infinite loop of away messages
1991 if both clients are away. The affected file is
1992 lib/silcclient/client_prvmsg.c.
1994 * Fixed client crash if /NICK was given without arguments.
1995 Affected file lib/silcclient/command.c.
1997 * Server does not send the invite list in INVITE command back
1998 to the client if the list was not altered. Added this notion
1999 to the protocol spec as well. Affected file silcd/command.c.
2001 Fixed possible crash in INVITE command by checking the
2002 value of silc_server_get_client_route command.
2004 * Fixed the INVITE notify type handling. The arguments are now
2005 taken in correct order and client does not crash. The affected
2006 file is irssi/src/silc/core/silc-channels.c.
2008 Removed the "Inviting xxx to channel" message from the
2009 client library away and let the application handle it.
2010 Affected file lib/silcclient/command.c. Added that message
2011 to Irssi SILC client's message formats.
2013 * Fixed CMODE command crash in client. It now checks the
2014 amount of arguments correctly and does not crash. The affected
2015 file is lib/silcclient/command.c.
2017 * Do not create new channel automatically in silc_channels_join
2018 but check whether the channel by that name already exists.
2019 Affected file irssi/silc/core/silc-channels.c.
2021 * Do not send the SERVER_SIGNOFF to router if the disconnected
2022 entity was the router. Affected file silcd/server.c.
2024 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2025 SILC client as it was missing from there.
2027 Added the handling of the KICK notify to the Irssi SILC client
2028 as it was missing. Added "you have been kicked" message to
2029 Irssi SILC client's message modules formats.
2031 Added the handing of the KILL notify to the Irssi SILC client
2032 as it was missing. Added the kill message module formats
2035 The affected file is irssi/src/silc/core/silc-channels.c.
2037 * The router did not save the channel mode the server announced.
2038 Affected file silcd/packet_receive.c.
2040 * Fixed a possible crash in INFO command in server. If the
2041 server did not provide the server info it crashed. Affected
2042 file silcd/command.c.
2044 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Fixed the GETKEY command in the server to check also the
2047 global list. Otherwise the GETKEY would not work correctly
2048 in normal SILC server. Affected file silcd/command.c.
2050 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Fixed GETKEY crash, it crashed if the command did not succseed.
2054 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2057 is now real and not just an macro interface to GMP.
2059 Removed the entire GMP from the source tree and imported new
2060 NSS MPI library instead. Reason for removing GMP is that it is
2061 extremely large and compiles extremely slow. The NSS MPI
2062 is only a few files and compiles in less than 10 seconds.
2063 The speed is also about the same as GMP. The MPI is imported
2064 to lib/silcmath/mpi.
2066 If the system has GMP installed we will still use the GMP.
2067 If it is not then the NSS MPI will be compiled.
2069 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Merged a long nickname (127 characters long) crash bugfix from
2072 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2074 * Merged a freed memory reference bugfix from Irssi CVS tree.
2075 Affected file irssi/src/core/commands.c.
2077 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Added the server's public key sving and verification to the
2080 server when performing the SKE. This was missing and the
2081 remote server's (or router's) public key was accepted without
2082 checking whether we have it previously or trust it at all.
2083 Affected file silcd/protocol.c.
2085 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * Check in the silc_server_timeout_remote if protocol is active
2088 and make sure that the protocol's final callback is called so
2089 that all memory if freed. Affected file silcd/server.c.
2091 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * silc_server_whois_send_reply crashed the server if the nickname
2094 was 127 characters long. Affected file silcd/command.c.
2096 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Added sanity check to the silc_server_new_client. If the hostname
2099 is provided inside username then check that the provided hostname
2100 really is the same as the resolved one. If the hostname was not
2101 resolved then check it from the public key. Affected file is
2102 silcd/packet_receive.c.
2104 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2105 if the server disconnected us and the connection is not valid
2106 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2108 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2109 the library to the lib/silcutil/silcutil.[ch].
2111 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Close log file after open. Affected file
2114 lib/silcutil/silclog.c.
2116 * Check whether sock == NULL in silc_client_send_packet and return
2117 if it is. Affected file lib/silcclient/silcclient.c.
2119 * Check rec->entry == NULL in the Irssi SILC Client before
2120 sending the channel message. Affecte file is
2121 irssi/src/silc/core/silc-servers.c.
2123 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Merged a splitted window bugfix from Irssi CVS tree. The
2126 affected file is irssi/src/fe-text/textbuffer-view.c.
2128 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2129 It did not print nickname.
2131 * Improved the distributions system a bit.
2133 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2136 irssi/src/fe-text/gui-window.c.
2138 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2139 to in-active server. The affected file is
2140 irssi/src/silc/core/client_ops.c.
2142 * Resolve the client in USERS command reply if the entry does
2143 not have username resolved. The affected file is
2144 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2145 command to WHOIS command to really resolve stuff. The USERS
2146 is not used any more in any critical section so WHOIS can
2147 be used even though it might be slower than IDENTIFY.
2149 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2152 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Changed the protocol API a bit more consistent in the
2155 lib/silccore/silcprotocol.[ch].
2157 * Changed the following headers to ROBODoc format:
2159 lib/silccore/silcpayload.h
2160 lib/silccore/silcprotocol.h
2161 lib/silccore/silcsockconn.h
2163 All core library headers are now formatted.
2165 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Fixed a bug in Irssi SILC client; do not show that you are
2168 server/router operator if you really are not. Affected file is
2169 irssi/src/silc/core/client_ops.c.
2171 * Renamed silc_command_free_payload to silc_command_payload_free.
2172 Affected file lib/silccore/silccommand.h
2174 * Added silcmath.h to include the prototoypes of various routines
2175 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2178 * Changed the following headers to ROBODoc format:
2180 lib/silccore/silcchannel.h
2181 lib/silccore/silccommand.h
2182 lib/silccore/silcid.h
2183 lib/silccore/silcidcache.h
2184 lib/silccore/silcmode.h
2185 lib/silccore/silcnotify.h
2186 lib/silccore/silcpacket.h
2187 lib/silcmath/silcmath.h
2189 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Added checking to the server code not to start the server if
2192 ciphers and stuff are not configured properly. Affected files
2193 silcd/serverconfig.[h] and silcd/server.c.
2195 * Changed the layout of the header files of the public interfaces
2196 in the SILC libraries. The new layout supports ROBODoc
2197 documentation tool (and some others) so that it is easy to create
2198 a library reference manual. All the other headers and source
2199 code must still follow the CodingStyle document. Also source
2200 code must not include these ROBODoc stuffs, only the headers.
2201 Furthermore, all public interface headers must now be named
2202 by using `silc' prefix, example: silcapi.h, silccipher.h.
2203 Some files were renamed due to this. All the other headers
2204 must not be used as public interfaces. I will update the
2205 CodingStyle document later. Changed following headers, so far:
2207 lib/silcclient/silcapi.h
2208 lib/silccore/silcauth.h
2209 lib/silccore/silcprivate.h
2210 lib/silccrypt/silcdh.h
2212 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2216 * Removed silc_client_packet_send_flush from the client library
2217 as it is not needed. Affected file lib/silcclient/client.[ch].
2219 * Added printing of message of unresolved authentication method
2220 to the Irssi SILC client. Added it to the module formats.
2221 Removed the same message from the client library.
2223 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * Added new distribution feature, DISTLABEL. Every distribution
2226 can define own preprocessor label that can be used in the
2227 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2228 file distributions, acconfig.h.pre and prepare.
2230 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Added Makefile.defines_int to include the actual definitions
2233 for Makefile.defines.in. Tested the new distribution system,
2234 created distributions and tested installation.
2236 * Added AWAY message printing to the Irssi SILC client. Added
2237 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2239 * Added SCONNECT command to call the SILC's CONNECT command.
2240 Cannot use CONNECT directly since Irssi uses that internally.
2241 Affected file irssi/src/silc/core/silc-servers.c.
2243 Added ACTION local command. It is same as ME command but takes
2244 the channel as mandatory argument.
2246 Rewrote some of the Irssi's help files to suite for SILC
2249 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Added Makefile.defines[.in] that should for now on be included
2252 in all Makefile.am file in the source tree. That file includes
2253 all common compilation definitions for SILC source tree.
2255 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Minor changes to the ./prepare script to change the package
2258 name according the distribution name to the configure.in.
2260 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Created new distribution system. Added file `distributions'
2263 that defines all the distributions that can be created out of
2264 the SILC source tree. The ./prepare script now reads that
2265 file to determine how to prepare the distributions. The
2266 first argument to the ./prepare is the name of the distribution
2267 and second is the version of the distribution. If given
2268 without arguments it creates the default (toolkit) distribution
2269 with the default version (defined in ./prepare).
2271 All Makefile.am files that are subject to the distributions
2272 are now named as Makefile.am.pre. These are ./Makefile.am
2273 and lib/Makefile.am. Others may be changed later.
2275 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Added invite list, ban list, some key management and connection
2278 error message printing to module formats in the Irssi SILC client.
2280 * Added new silc_client_set_away_message to set the away message
2281 that is back to the person who sent private message. The
2282 affected file lib/silcclient/silcapi.h and the
2283 lib/silcclient/client_prvmsg.c.
2285 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Fixed the private message sending in the Irssi SILC client,
2288 added local command KEY to the Irssi SILC client.
2290 Added key management and key agreement message formats to the
2291 irssi/src/fe-common/silc/module-formats.[ch].
2293 Added USERS (alias WHO) printing, server/router operator
2294 indication and LIST command printing to the module formats.
2296 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Fixed channel joining notify handling, cumode notify handling
2299 from Irssi SILC client.
2301 * Added SILC specific module-formats to the Irssi SILC client so
2302 that SILC specific message hilighting, colors etc is possible.
2303 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2305 Added channel mode, channel user mode, actions, notices,
2306 whois and whowas printing to the the module-formats.c.
2308 * Fixed a bug in channel deletion in the server. The channel
2309 is not left to the cache even if the channel founder auth mode
2310 is set when there are no users anymore on the channel. Affected
2311 file silcd/server.c.
2313 * The silc_net_localhost now resolves the entire hostname including
2314 the domain name. Affected file lib/silcutil/silcnet.c.
2316 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Changed the ask_passphrase client operation to be ascynchronous.
2319 It has now a completion callback and a context that the
2320 application must call after it has got the passphrase from
2321 the user. Affected files lib/silcclient/silcapi.h,
2322 lib/silcclient/protocol.c, lib/silcclient/command.c and
2325 Added SilcAskPassphrase callback that the application calls
2326 to deliver the passphrase to the library.
2328 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2329 The public key verification and especially a certificate
2330 verification is asynchronous procedure.
2332 Added new SILC_SKE_STATUS_PENDING status to indicate the
2333 request is pending and a callback will be called to finalize
2336 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2337 indicate that remote end did not send its public key (or
2338 certificate), even though we require it. Added check for this
2339 condition in the SKE. This was a security bug, now fixed.
2341 Defined new SilcSKEVerifyCbCompletion callback that is called
2342 when the verification process is completed.
2344 The affected files lib/silcske/silcske_status.h and
2345 lib/silcske/silcske.[ch].
2347 * Changed the verify_public_key client operation to be async
2348 as well. Defined SilcVerifyPublicKey callback that is used to
2349 indicate the success of the public key verification process.
2351 Changed the server and client to use the new async client
2354 * Changed the Irssi SILC client's internal scheduler to be called
2355 twice as many times as it used to be. As a result the client
2356 should be a bit faster now. Affected file is
2357 irssi/src/silc/core/silc-core.c.
2359 * Added support to Irssi SILC client of asynchronous public key
2360 verification and passphrase inquiry. Affected file is
2361 irssi/src/silc/core/silc-core.c.
2363 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Do not say "You have left channel %s" in client library.
2366 Moved it to the application. Affected files are
2367 lib/silcclient/command.c and silc/client_ops.c.
2369 * Fixed silc_client_get_clients. Command context was not
2370 duplicated and was freed memory in the callback. Affected
2371 file lib/silcclient/idlist.c.
2373 * Do not say "you are now talking..." on JOIN command in the
2374 client library. The appliation must handle it.
2376 * Do not say ".. changed topic to" in command reply in the
2377 client libary. The application must handle it.
2379 * Fixed TOPIC command sending in the client library.
2381 * Fixed a memory leak in silc_client_command_free in the file
2382 lib/silcclient/command.c.
2384 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Imported a modified version of Irssi client to the source tree.
2387 The Irssi will be used to create a new client called
2388 Irssi SILC. Imported to irssi/.
2390 Added silc_core_init_finish function to the Irssi. Affected
2391 file irssi/configure.in.
2393 A lot changes in the Makefile.ams around the irssi tree.
2395 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Do not rehash if the new size is same as the old size of the
2398 hash table, in the silc_hash_table_rehash*. The affected file
2399 lib/silcutil/silchashtable.c.
2401 * Replaced hash_table_del_by_context calls from the server
2402 (when channel->user_list and client->channels) to the
2403 hash_table_del as it is sufficient and faster.
2405 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Added silc_hash_table_list, silc_hash_table_get and the
2408 SilcHashTableList structure to provide an alternative way to
2409 traverse the hash table. The affected files are
2410 lib/silcutil/silchashtable.[ch].
2412 * Changed the server's idlist routines to use the hash table
2413 routines to optimize the code.
2415 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Replaced the client entry's `channel' list and channel entry's
2418 `user_list' list to hash tables for optimized lookup. Changed
2419 the code to use the hash table interface around the code.
2420 Affected file lib/silcd/idlist.[ch].
2422 * Added `auto_rehash' boolean argument to the function
2423 silc_hash_table_alloc to indicate whether the hash table should
2424 auto-rehash when it thinks is appropriate time. It will
2425 increase the hash table size if the there is twice as much
2426 entries in the table than the size of the table, and will
2427 decrease the size if there are twice as less entries than
2428 the size of the table.
2430 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2434 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * silc_idcache_purge_by_context deletes the entry now by context
2437 as it is supposed to do. Affected file lib/silccore/idcache.c.
2439 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2440 client is not anymore valid (WHOWAS givens the info) and not
2441 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2443 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Removed the `data' and `data_len' arguments from the ID Cache
2446 interfaces and added `name' argument. ID Cache does not handle
2447 anymore the binary data only a names associated with given ID.
2449 * When hashing a Client ID with silc_hash_id the entire ID is
2450 not hashed anymore, instead only the hash of the Client ID is
2451 hashed. This way we can access the Client ID from the cache
2452 with Client ID but with the hash of the ID (which is a hash of
2453 the nickname) as well without any difference in performance.
2455 Added also silc_idcache_find_by_id_one_ext to do one on one
2456 searching when we have the actual ID. Added also function
2457 silc_hash_client_id_compare. The affected files are
2458 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2460 * When hashing the name associated with a ID it is always done
2461 in lowercase. This way we can access the cache without worrying
2462 about case-sensitivity, even though, for example nicknames are
2465 * Fixed a bug in server with channel message sending. It put
2466 wrong ID type as destination ID. The affected file
2467 silcd/packet_send.c.
2469 * silc_idcache_del_by_context now deletes from all hash tables
2470 by context. Affected file lib/silccore/idcache.c.
2472 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Changed the client library to use the new ID Cache interface.
2475 Changes around the source tree.
2477 * Added silc_hash_table_rehash_ext to rehash with specific
2478 hash function. Affected file lib/silcutil/silchashtable.[ch].
2480 * Added silc_hash_string_compare to compare two strings in the
2481 hash table. Affected file lib/silcutil/silcutil.[ch].
2483 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Added new function silc_idcache_del_by_context into the
2486 lib/silccore/idcache.[ch].
2488 * Changed the server's ID list routines to use the new ID Cache
2489 interface. Changes around the source tree.
2491 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Added silc_hash_table_del[_by_context]_ext functions in to the
2494 lib/silcutil/silchashtable.[ch].
2496 Removed silc_hash_table_find_all* routines and added new
2497 silc_hash_table_find_foreach to replace them.
2499 Added silc_hash_table_replace_ext function as extended
2500 replacing function. Separated the simple hash table interface
2501 from the extended hash table interface in the file
2502 lib/silcutil/silchashtable.h.
2504 * Fixed minor bugs and changed it to use some of the new
2505 hash table functions in lib/silccore/idcache.c
2507 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2509 * Added new function silc_hash_table_find_all to return all keys
2510 in the hash table by the specified key. As the hash table is
2511 collision resistant it also makes it possible to have several
2512 duplicate keys in the hash table. This function may be used to
2513 find all of the keys from the hash.
2515 Added user_context arguments to the SilcHashFunction,
2516 SilcHashCompare and SilcHashDestructor to deliver user specified
2519 Added new fuctions silc_hash_table_find[_all]_ext to do
2520 extended lookup with specified hash and compare functions and
2521 specified user contexts.
2523 Added new function silc_hash_table_add_ext to add the key
2524 with specified hash function and user context.
2526 Added new function silc_hash_table_foreach to traverse all
2527 entrys in the hash table. Added SilcHashForeach callback
2530 Added new function silc_hash_table_del_by_context to delete
2531 the entry only if the context associated with the key matches.
2533 Affected files are lib/silcutil/silchashtable.[ch].
2535 * Removed silc_hash_[server/client/channel]_id and added just
2536 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2537 silc_hash_id_compare to compare two ID's using as the hash table
2538 comparison function. Added also silc_hash_data to hash
2539 binary data and silc_hash_data_compare to compare it.
2541 * Removed silc_idlist_find_client_by_hash as it is not needed
2542 anymore. Affected file silcd/idlist.[ch].
2544 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2545 to use internally the SilcHashTable. The new ID Cache is a lot
2546 faster than the old one. Some of the ID Cache interface was also
2547 rewritten and obsolete and stupid functions were removed.
2549 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Added entry_count field to the SilcHashTable to keep the number
2552 of the entries in the table. Implemented the function
2553 silc_hash_table_rehash. Added new function
2554 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2556 Fixed a minor bug in silc_hash_table_free.
2558 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2559 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2560 into the lib/silcutil/silcutil.[ch].
2562 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Implemented a collision resistant hash table into the
2565 lib/silcutil/silchashtable[ch]. See the header and the source
2566 for the SilcHashTable API.
2568 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Merged dotconf version 1.0.2 into lib/dotconf.
2572 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Do not compile anything in lib/silcsim/* if the SIM support
2575 is not enabled. The tree should now compile without problems
2578 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2580 * Compiled the SILC under cygwin. Compiled and tested briefly
2581 without problems. More tests needed. The SIMs didn't compile
2584 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2586 * Fixed possible crash in silc_get_username in the
2587 lib/silcutil/silcutil.c.
2589 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Fixed a va_arg in silc/client_ops.c.
2593 * Oops, RC5 routines were named AES and caused some problems
2594 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2596 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Added new SilcIDIP structure into the lib/silccore/id.h and
2599 replaced the old `ip' fields from all SILC ID's to that type.
2600 This is a step towards IPv6 support.
2602 The silc_id_get_len takes now the ID as an extra argument.
2603 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2604 both IPv4 and IPv6 based ID's.
2606 The affected files are lib/silccore/id.[ch] and other files
2607 around the tree using these routines.
2609 * Removed the ID length arguments in server from various
2610 silc_server_send_notify_* routines -> they are not needed
2613 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Fixed memory leak in silc_encode_pem_file in the file
2616 lib/silcutil/silcutil.c.
2618 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Check minor version as well in the SKE. Affected files are
2621 silcd/protocol.c and lib/silcclient/protocol.c.
2623 * Added --identifier option to the server so that an identifier
2624 can be when creating the public key for the server. Affected
2625 file is silcd/silcd.c.
2627 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2628 lib/silccrypt/silcpkcs.c.
2630 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Register default ciphers and stuff when using -C option with
2633 the server. Affected file sildc/silcd.c.
2635 * Put back the servers public key filename format, it is better
2636 than the new one. For now, the client keys are saved with the
2637 new filename format. The affected file silc/client_ops.c.
2639 * Implemented the Cipher API for the rest of the ciphers that
2640 did not implement it or implemented it the wrong way.
2642 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Register default ciphers and stuff when using the -S option
2645 in the client. Affected file silc/silc.c. Same also when
2646 creating new key pair with -C option.
2648 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Fixed the silc_verify_public_key client operation function to
2651 save the public keys differently. The fingerprint is now
2652 used as filename and not the hostname. This way also the
2653 client keys are saved uniquely and not with hostnames. The
2654 affected file is silc/client_ops.c.
2656 * Trimmed the silc_hash_fingerprint function to remove extra
2657 whitespaces from the end of the fingerprint. The affected
2658 file is lib/silccrypt/silchash.c.
2662 * Added silc_cipher_register_default function to register all
2663 default ciphers. It can be used when configuration files
2664 does not exist and the application does not want any specific
2665 ciphers in any specific order.
2667 The SilcDList is now used as silc_cipher_list dynamically
2668 allocated cipher list. Removed the static list all together
2669 and now all ciphers must be allocated to the dynamic list.
2670 The silc_cipher_alloc routine was changed to check only the
2673 All silc_cipher_* routines that used to return int returns
2676 The affected files lib/silccrypt/silccrypt.[ch].
2678 * The same thing was done to silc_hash_* as for silc_cipher_*
2679 routines. Affected files lib/silccrypt/silchash.[ch].
2681 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2682 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2683 Added also silc_pkcs_[un]register[_default] functions.
2684 Removed the data_context from the PKCS API.
2686 * Added silc_hmac_register_default function to register default
2687 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2688 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2689 to unregister all hmacs at once.
2691 * Register the default ciphers, hash functions, PKCSs and HMACs
2692 if client's configuration file does not exist. The affected
2695 * The client did not load the hash functions from the SIM
2696 modules at all. Added support for this. Affected file is
2697 silc/clientconfig.c.
2699 * When decoding public key with silc_pkcs_public_key_decode, check
2700 the supported algorithm only if PKCS are registered. Affected
2701 file lib/silccrypt/silcpkcs.c. The same was done with the
2702 silc_pkcs_private_key_decode.
2704 * Fixed the SILC List routines to keep the list always in order.
2705 It used to change the list's order when traversing the list but
2706 not it preserves the order. Affected file lib/trq/silclist.h.
2708 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Added the client library to use the SilcSocketConnection's
2711 reference counter (by silc_socket_dup) to prevent the bug that
2712 the socket object may be freed underneath async operation.
2714 * The name resolv library checking fixes in the configure.in.pre.
2717 * Created new version of the protocol drafts for future
2718 development. The -03 drafts are the ones that will be changed
2719 in the trunk now and the -02 will remain as they are.
2721 * Send list of CUMODE notifys to the router when announcing
2722 the channel users to the router. Affected file silcd/server.c.
2723 If the router receiving channel founder CUMODE for a channel
2724 that already has channel founder it will send CUMODE notify
2725 to the sender to remove the channel founder rights from the
2726 announced client. Affected file silcd/packet_receive.c.
2728 * The CUMODE notify may now use Server ID as well as the entity
2729 who changes the mode. Updated protocool specs.
2731 * Updated INSTALL and README files.
2733 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * New web pages in the http://silc.pspt.fi. The pages was
2740 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Implemented the [DenyConnectin] config section in the server.
2743 Added silc_server_config_denied_conn to check whether incoming
2744 connection is denied. Affected file silcd/serverconfig.[ch].
2746 * Do not check the ports when checking the incoming configuration
2747 data if the port is 0, meaning any. Affected file is
2748 silcd/serverconfig.c.
2750 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Fixed buffer overflow in silc_string_compare in the file
2753 lib/silcutil/silcutil.c.
2755 * Fixed double free in silc_server_command_leave in the file
2758 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Fixed the version checking in the server. Affected file is
2763 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * Fixed the configuration data fetching when accepting new
2766 connections in the server. Affected file silcd/server.c.
2768 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Added `sender_entry' argument to the function
2771 silc_server_packet_relay_to_channel so that we can check
2772 whether some destination actually belongs to the same route
2773 the sender belongs (ie, we must not resend the packet to the
2774 sender). Affected file silcd/packet_send.[ch].
2776 * Added `servername' field to the SilcClientEntry in the server
2777 to hold the name of the server where client is from. Affected
2778 file is silcd/idlist.h.
2780 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Moved the channel message encrypting in the router betwen
2783 router connections from silc_server_channel_message to the
2784 silc_server_packet_relay_to_channel since we want to check
2785 whether we have anybody channel before encrypting anything.
2786 Affected files silcd/packet_[receive/send].c.
2788 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Fixed the [AdminConnection] server config section to support
2791 multiple entries. Affected file silcd/serverconfig.c.
2793 * Added support into the server to check the validity of the
2794 incoming connection before executing any KE or authentication
2797 * The connection configuration is now saved to the KE and
2798 connection auth protocol contexts and not fetched anymore in
2799 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2801 * The local hosts listenning address and port is also resolved
2802 now when starting the server. We want to have the socket object
2803 to include the real address and port for the listener. Added
2804 new function silc_net_check_local_by_sock into the files
2805 lib/silcutil/silcnet.[ch].
2807 * Fixed a broadcast bug in server -> do not broadcast if we
2810 * Fixed a routing bug. Do not route broadcast packets ever.
2811 Broadcast packets must be processed always and not routed since
2812 they may be destined to some other host than yourself and thus
2813 would get routed without no good reason. Affected file is
2816 * Added function silc_server_config_is_primary_route to check
2817 whether primary router connection has been configured (a router
2818 configuration that we are initiating). If there is not, we
2819 will assume that there is only two routers in the SILC network
2820 and we will use the incoming router connection as our primary
2821 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2823 * Changed the order of the broadcasting. Broadcast _after_ the
2824 packet has been processed not before. Affected file is
2827 * Fixed a [ClientConnection] parsing bug. The port was never
2828 parsed correctly thus resulting to port 0. Affected file
2829 silcd/serverconfig.c.
2831 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2832 argument and did not set the broadcast packet flag. Affected
2833 file silcd/packet_send.c. Fixed same bug in the function
2834 silc_server_send_notify as well.
2836 * If we receive NEW_ID packet for our own ID in the server, ignore
2839 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Removed the nickname from the Private Message Payload.
2844 Updated the code and the protocol specs.
2846 * Updated protocol specs for submitting to the IETF.
2848 * Tweaked the Random Number Generator a bit. Affected file
2849 lib/silccrypt/silcrng.c. Exported a new function
2850 silc_rng_[global]_add_noise which can be used to add more
2853 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Do not parse packets with different timeout when protocol
2856 is active -> may cause problem with rekey. Affected file
2859 * When server receives signoff notify it must not create
2860 new channel key if the client is on any channels since the
2861 sender of the signoff notify will create it.
2863 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * Added printing of error messages during SKE protocol from the
2866 failure packet sent by server during SKE. Affected file
2869 * Removed the client's failure_callback handling with timeout
2870 and handle it immediately when received.
2872 * The SKE library returned wrong type in SUCCESS and FAILURE
2873 packets. They must be 32 bit MSB not 16 bit MSB.
2875 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Ok, rewrote the logic of the re-key and now it seems to work.
2878 I tested it on high traffic with frequent re-keys without
2879 problems. Added hmac_receive (and renamed hmac to hmac_send)
2880 in SilcClientConnection in lib/silcclient/client.h and
2881 in SilcIDListData in silcd/idlist.h. Also, removed the
2882 SilcPacketParserContext's cipher and hmac fields as they are
2883 not needed anymore and actually caused some problems when
2884 the ciphers and hmac's changed underneath the packet parser.
2886 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * If re-key protocol is active then process the incoming packets
2889 synchronously since we must assure that icoming packets encrypted
2890 with the old key is processed before the new keys is set to
2891 use. This is true other packets than for REKEY packets.
2892 Affected file silcd/server.c. The same was done to client library
2893 as well, affected file lib/silcclient/client.c.
2895 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Fixed bug in client and server to accept the force send if
2898 the packet is send from silc_[server/client]_packet_process
2899 function. Otherwise the packets are never delivered, oops.
2901 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Disable force sending of packets when REKEY protocol is active.
2904 We must assure that no packet is sent directly when rekey is
2905 performed. All packets must be sent through packet queue.
2906 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2907 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2908 function is silc_[server/client]_packet_send_real to check
2911 * Replaced the SIM paths from example config files to
2912 /usr/local/modules. Also, make install creates now
2913 /usr/local/silc/logs directory to hold all the SILC server
2916 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2918 * Made the configure.in.pre work on Solaris. Patch by salo.
2920 * Made all ciphers compatible with non-x86 machines. Defined
2921 CBC mode macros into lib/silccrypt/ciphers_def.h.
2923 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Fixed the make install.
2927 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * When MAC computation fails the silc_packet_decrypt returned 0
2930 even though it was supposed to return -1. Fixed this. The
2931 affected file is lib/silccore/silcpacket.c.
2933 * Do not replace the config files in /etc/silc (in make install)
2934 if they already exist. Affected file ./Makefile.am.
2936 * Do not send re-key packets immediately but through packet queue.
2937 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2939 * Changed silc_net_check_host_by_sock to return FALSE if the
2940 IP/DNS could not be resolved. Though, it returns the IP address
2941 now even if it could not resolve it (but returns also FALSE).
2942 Affected file lib/silcutil/silcnet.[ch].
2944 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Added silc_pkcs_decode_identifier to decode the public key's
2947 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2948 Added also silc_pkcs_free_identifier. Added also new context
2949 SilcPublicKeyIdentifier.
2951 * Added -S option to the silc client. It is used to dump the
2952 contents of the specified public key file.
2954 * Changed the PKCS api to return the public key length when
2955 setting the public key.
2957 * Fixed a fatal bug in the public and private key file loading.
2958 Affected file lib/silccrypt/silcpkcs.c.
2960 * Execute the packet parsing for client with zero (0) timeout
2961 if the protocol is active. Affected file silcd/server.c.
2963 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Made the key generation options to the silcd program. Added
2966 -C option, equivalent to client's option.
2968 * Added new [ServerKeys] config section to the server. It
2969 configures the server's public and private key.
2971 * Defined generic Public Key Payload into the protocol
2972 specification to send specific type of public keys and
2975 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2976 public key or certificate.
2978 * Implemented the GETKEY command to the server and to the
2979 client library and on user interface.
2981 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Made preliminary `make install' work.
2985 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Added SilcServerRekey context into silcd/idlist.h.
2989 * Added the PFS support as defined in the specification to the
2990 SKE protocol. Affected files lib/silcske/*.c.
2992 * Added `ske_group' field to the SilcServerRekey context to hold
2993 the number of the SKE group that is used with PFS in re-key.
2994 Affected file silcd/idlist.h.
2996 * Added PFS re-key support to the server. Affected file is
2999 * Added silc_protocol_cancel to cancel execution of the next
3000 state of the protocol. Affected file is
3001 lib/silccore/silcprotocol.[ch].
3003 * Added the re-key support with and without PFS to the client
3004 library. Re-key is performed once in an hour, by default.
3006 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3007 Added silc_client_rekey_callback and silc_client_rekey_final.
3008 Affected files are lib/silcclient/protocol.[ch] and
3009 lib/silcclient/client.[ch].
3011 * Removed the `hmac_key' and `hmac_key_len' fields from the
3012 SilcClientConnection structure; not needed. Affected file is
3013 lib/silcclient/client.h.
3017 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Do not ask whether user wants to use the negotiated private key
3020 for private messages, just use it. Affected file is
3021 silc/local_command.c.
3023 * Added `send_enc_key' and `enc_key_len' fields to the
3024 SilcIDListData structure since they are needed in the re-key
3025 phase. Affected file is silcd/idlist.[ch].
3027 * Implemented the simple re-key protocol into the server.
3028 Affected files silcd/server.c and silcd/protocol.[ch]. The
3029 re-key will be performed once in an hour, by default.
3031 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3032 Added silc_server_rekey, silc_server_rekey_callback and
3033 silc_server_rekey_final.
3035 * Removed Tunneled flag from the protocol. Updated the code
3036 and the specifications.
3038 * Adde `pfs' field to the SilcIDListData to indicate whether
3039 the PFS is to be performed in the re-key. Affected file is
3042 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3045 int64 of at least the xintXX size. If void * is less that 4
3046 bytes uint32 * will be used. Defined bool as boolean.
3048 * Changed _ALL_ unsigned long and unsigned int to uint32,
3049 unsgined short to uint16 in the source tree.
3051 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3052 not handle clients that has entry->data.registered == FALSE.
3053 They are not in the network anymore. Affected file is
3056 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Implemented the sending of the SERVER_SIGNOFF notify in the
3059 server. Affected file is silcd/server.c.
3061 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3062 Added also silc_notify_payload_encode_args into the
3063 lib/silccore/silcnotify.[ch].
3065 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3066 Affected file silcd/packet_receive.c.
3068 * Implemented the SERVER_SIGNOFF notify handling in the client
3069 library. Affected file lib/silcclient/client_notify.c. Also,
3070 implemnted the printing of the SERVER_SIGNOFF info to the
3071 application. Affected file silc/client_ops.c.
3073 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3074 if the deleting was successful. Affected file silcd/idlist.[ch].
3076 * Added support for public key authentication in the connection
3077 authentication protocol in the client library. Affected file
3078 lib/silcclient/protocol.c.
3080 * Changed the server's silc_idlist_get_clients_by_* interface
3081 to support already allocated array so that new entries may be
3082 added to pre-allocated array. Affected file silcd/idlist.[ch].
3083 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3084 and command replies.
3086 * All command reply functions in the server now calls the
3087 pending command callback even if error occured. This way the
3088 error will be delivered to the client as well. Affected files
3089 silcd/command.c and silcd/command_reply.c.
3091 * Fixed INFO command to return local server's info if no server
3092 was provided. Affected file lib/silcclient/command.c.
3094 * Removed RESTART command for good. Updated the code and the
3097 * Rewrote parts of the task system. It is a bit simpler now.
3098 Removed unsued task priorities. The affected files are
3099 lib/silcutil/silctask.[ch].
3101 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Moved the USERS printing from the library to the application.
3104 Affected files lib/silcclient/command.c and silc/client_ops.c.
3106 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3110 * Added channel key re-key support. The re-key is perfomed
3111 only by the router and is done once in an hour. Added `rekey'
3112 field to the SilcChannelEntry in the server. Affected files
3113 silcd/server.c and silcd/idlist.h.
3115 * Added silc_task_unregister_by_context into the file
3116 lib/silcutil/silctask.[ch].
3118 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added SILC_UMODE_GONE mode to indicate when the client is not
3121 present in the SILC network. Added also support to the local
3122 command AWAY that will set this mode. Added support of showing
3123 "xxx is gone" in WHOIS command. The USERS command shows the
3124 gone status as well.
3126 * Fixed setting server and router operator privileges in the
3127 server's UMODE command. Affected file silcd/command.c.
3129 * Merged the SKE KE1 and KE2 payloads into one payload. The
3130 new KE payload is equivalent to the old KE2 payload.
3132 Cleaned up the SKE Start Payload parsing. It now uses the
3133 simple buffer unformatting to do the parsing. A lot faster
3136 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3137 to the SKE that is used to indicate whether both of the SKE
3138 parties should perform authentication. By default only the
3139 responder performs authentication. By setting this flag also
3140 the initiator must do authentication. By default it is unset
3141 since in normal SKE case, client to server connection, only
3142 the responder should do authentication. When doing SKE between
3143 two clients both should perform authentication. Updated the
3144 code and the protocol specs.
3146 * A little fix to IDENTIFY command in the server. Search the
3147 client first by hash not nickname. Affected file is
3150 * Fixed the silc_client_close_connection to support closing
3151 the client to client connections wihtout deleting too much
3152 data. Affected file lib/silcclient/client.c.
3154 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3155 are received if protocol used to be active but is not anymore
3156 the application would crash due to NULL pointer dereference.
3157 Affected files silcd/server.c and lib/silcclient/client.c.
3159 * Added `hash' field to the SilcClientConnection to include
3160 the hash function negotiated in the SKE protocol.
3162 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3163 to set the channel founder authentication data. A client can
3164 claim the founder rights later by providing the authentication
3165 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3166 This way the channel founder can regain the channel founder
3167 privileges even it is left the channel. This works only on
3168 local server and the client must be connected to the same
3169 server to be able to regain the founder rights. Updated the
3170 protocol specs accordingly.
3172 Added support to the CMODE command in the client to set the
3173 founder auth data. Read the README to see how to set it.
3175 Added support to the CUMODE command to claim the founder
3176 rights. Read the README to see how to do it.
3178 Added support for the founder authentication to the Channel
3179 Entry in the server. Affected file silcd/idlist.h.
3181 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3182 server's CMODE command. Affected file silcd/command.c.
3184 * Added the following new functions into lib/silccore/silcauth.[ch]:
3185 silc_auth_get_method and silc_auth_get_data.
3187 * The server now saves the remote hosts public key to the
3188 SilcIDListData pointer. Affected file silcd/protocol.c.
3190 * The normal server now does not remove the channel entry from
3191 the cache if the founder authentication data is set. It used
3192 to remove it if the founder was the last one on the channel on
3193 the server and left the channel. The auth data is saved and
3194 if the channel is re-joined later the old entry is used with
3195 the old auth data. Affected files silcd/command_reply.c and
3198 * Removed the `pkcs' field from the SilcIDListData structure
3199 in the server; it is not used. Affected file silcd/idlist.h.
3201 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Fixed packet processing on slow links. Partial packets were
3204 never re-processed because the incoming data buffer was cleared
3205 by the application. Application must not directly clear the
3206 sock->inbuf, the packet processing routines handle it. Fixed
3207 this in client library and in server.
3209 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Fixed the WHOIS and IDENTIFY send reply function to really
3212 check whether to send list or just one entry. Affected file
3215 * Cleaned up the LEAVE command's channel key distribution. The
3216 affected file silcd/command.c.
3218 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3219 can enforce the channel mode as well. In that case the ID
3220 includes the ID of the server. The code now enforces the
3221 mode change if the router have different mode than the server.
3223 * The notify client operation with CMODE_CHANGE notify can now
3224 return NULL client_entry pointer if the CMODE was not changed
3225 by client. Application must check for this.
3227 * Added <Server ID> argument to INFO command to support server
3228 info fetching by Server ID.
3230 * Added silc_server_announce_get_channel_users to get assembled
3231 packets of channel users of the specified channel. Affected
3232 file silcd/server.[ch].
3234 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3235 was freed underneath the ID Cache.
3237 * Re-announce clients when the server received CHANNEL_CHANGE
3238 notify from the router. Affected file silcd/packet_send.c.
3240 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3243 crashed since it did not handle the fact that there is no cipher
3244 called "3" and didn't check the error condition. Now fixed.
3246 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3247 flag. It can be used to send message requests.
3249 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Implemented the RESTART command in the client.
3253 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3254 notice type messages. Added notice printing to the user
3257 * The channel keys are not re-generated if the channel's mode
3258 is PRIVKEY, ie private key on the channel exists. Affected
3259 files silcd/server.c and silcd/command.c.
3261 * Fixed a little bug in channel message delivery when channel
3262 private keys are set in the server. Affected file is
3263 silcd/packet_send.c.
3265 * Changed the setting on channel->on_channel = TRUE from the
3266 silc_client_save_channel_key to the JOIN command reply. The
3267 key payload is not received if the private channel key is set.
3268 Affected file lib/silcclient/command_reply.c and the
3269 lib/silcclient/client_channel.c.
3271 * When the CMODE_CHANGE notify is sent and the channel private
3272 key mode is removed the channel key must be re-generated in
3273 other cells as well. Added this support for the router in the
3274 silcd/packet_receive.c.
3276 * Added new local command NOTICE to send notice message on
3277 channel. Affected file silc/local_command.[ch].
3279 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added new local command ME to the client. It is used to send
3282 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3283 some action. Affected file silc/local_command.[ch].
3285 * Changed channel_message and private_message client operations
3286 to deliver the message flags to the application. Added also
3287 the `flags' arguments to the silc_client_send_channel_message
3288 and silc_client_send_private_message functions. Affected file
3291 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Redefined the Private Message Payload to support private message
3294 keys and to support the new private message flags. Updated
3295 the protocol specs. Flags makes it possible to have for example
3296 CTCP style messages.
3298 * Added new type SilcPrivateMessagePayload and defined an API
3299 for it in the lib/silcclient/silcprivate.[ch].
3301 * Tested private message private keys successfully. Tested the
3302 private message key set, unset and list commands with the new
3305 * Redefined the Channel Message Payload to include the channel
3306 message flags (equal with private message flags) to support
3307 for example CTCP style messages.
3309 * Defined some of the message (for channel and private message)
3310 flags. Updated the protocol specs and added the flags to the
3311 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3313 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Added SilcKeyAgreementStatus type to the key agreement routines
3316 to indicate the current status and error if one occured.
3317 The status types are defined in the lib/silcclient/silcapi.h.
3319 * Added new local command KEY that is used to set and unset private
3320 keys for channels, set and unset private keys for private messages
3321 with remote clients and to send key agreement requests and
3322 negotiate the key agreement protocol with remote client. The
3323 key agreement is supported only to negotiate private message keys,
3324 it currently cannot be used to negotiate private keys for channels,
3325 as it is not convenient for that purpose.
3327 * Fixed a minor pending callback setting bug in the function
3328 silc_client_get_client_by_id_resolve, now the function works.
3329 Affected file lib/silcclient/idlist.c.
3331 * Added function silc_net_get_local_port to get local bound
3332 port by socket. Added to lib/silcutil/silcnet.[ch].
3334 * Added `sockets' and `sockets_count' fields to the SilcClient
3335 object. They hold the sockets of the listenning sockets in
3336 the client. Listenning sockets may be for example the key
3337 agreement server. Affected file lib/silcclient/client.[ch].
3338 Added functions the silc_client_add_socket and the
3339 silc_client_del_socket. They are exported to the application
3342 * Added ~./silc/clientkeys to support other client's public keys.
3344 * Renamed verify_server_key client operation to verify_public_key
3345 and added one argument to indicate the type of the connection
3346 (server, client etc.).
3348 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Added silc_server_connection_auth_request to handle the
3351 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3352 silcd/packet_receive.[ch].
3354 * Added silc_server_send_connection_auth_request into the
3355 silcd/packet_send.c to send the connection auth request packet.
3357 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3360 * Fixed the public key authentication in responder side in the
3361 server. The `auth_data' pointer includes the SilcPublicKey
3362 not the path to the public key. Affected file silcd/protocol.c.
3364 * Implemented the public key authentication in the initiator side
3365 in the server. Affected file silcd/protocol.c.
3367 * Removed the [RedirectClient] config section from the server
3368 configuration. Is not needed and I don't want to implement it.
3370 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Cleaned up the CMODE command in the server. It now works
3373 correctly and supports all the modes defined in the protocol.
3374 Affected file is silcd/command.c.
3376 * Added `hmac_name' field to the SilcChannelEntry in the server
3377 to hold the default HMAC of the channel. It can be set when
3378 creating the channel (with JOIN command). Affected files
3381 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3382 type to indicate the change of the current cipher and hmac
3383 on the channel. Client can safely ignore the <cipher> argument
3384 (if it chooses to do so) since the CHANNEL_KEY packet will
3385 force the channel key change anyway. The <hmac> argument is
3386 important since the client is responsible of setting the new
3387 HMAC and the hmac key into use.
3389 * Fixed the CMODE command in the client library as well.
3391 * Tested CMODE command in router environment successfully.
3393 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Show the version of the remote client (or server) when connecting
3396 to the server. It is logged to the log file. Affected file
3397 is silcd/protocol.c.
3399 * Fixed the KILLED notify handling in the client library. The
3400 client must be removed from all channels when receiving the
3403 Also, do not remove the client entry when giving the KILL
3404 command but when the KILLED notify is received.
3406 * Removed silc_idlist_find_client_by_nickname from the server.
3407 Not needed anymore. Affected files silcd/idlist.[ch].
3409 * Implemented the CHANNEL_CHANGE notify type handling to the
3410 server. Affected file silcd/server.c.
3414 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Added silc_server_send_notify_invite to send the INVITE
3417 notify between routers.
3419 * Implemented the INVITE command correctly to the server.
3421 * Implemented the INVITE notify type handling in the server.
3423 * Implemented the INVITE command to the client library and on the
3426 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Added function silc_server_get_client_resolve to find the
3429 client entry by ID from all ID lists and then resolve it
3430 (using WHOIS) if it cannot be found. Affected file is
3433 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Implemented the BAN command to the client library.
3437 * The JOIN command in the server now checks the invite list
3440 * Changed the silc_command_reply_payload_encode_va and the
3441 silc_command_payload_encode_va to support that if argument is
3442 NULL it ignores and checks the next argument. Affected file
3443 lib/silccore/silccommand.c.
3445 * Added silc_server_send_notify_ban to send the BAN notify
3446 type between routers.
3448 * Chaned the silc_notify_payload_encode to support that if
3449 argument is NULL it ignores and checks the next argument.
3450 Affected file lib/silccore/silcnotify.c.
3452 * Tested ban lists in router environment successfully.
3454 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Implemented BAN command to the server, in silcd/command.[ch].
3458 * Removed the BAN and INVITE_LIST modes from the CMODE command
3461 * Added function silc_string_match to regex match two strings.
3462 Affected files lib/silcutil/silcutil.[ch].
3464 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Redefined parts of the SilcChannelEntry in the server to support
3467 the new ban and invite lists.
3469 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Redefined the INVITE command. The same command can be used to
3472 invite individuals to the channel but also to manage the invite
3473 list of the channel (to add to and remove from the invite list).
3474 Updated the protocol specs.
3476 * Added new command SILC_COMMAND_BAN that can be used to manage
3477 the ban list of the channel. Updated the protocol specs.
3479 * Removed the channel modes: the SILC_CMODE_BAN and the
3480 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3481 in the CMODE command. The equivalent features are now available
3482 using INVITE and BAN commands. Updated the protocol specs.
3484 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3485 in the network about change in the current ban list. The notify
3486 type is not used by the client.
3488 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3489 support the invite lists.
3491 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Added new function silc_string_regexify that converts string
3494 including wildcard characters into regex string that can
3495 be used by the GNU regex library. Added into the file
3496 lib/silcutil/silcutil.[ch].
3498 Added silc_string_regex_combine to combine to regex strings
3499 into one so that they can be used as one regex string by
3500 the GNU regex library. Added into the file
3501 lib/silcutil/silcutil.[ch].
3503 Added silc_string_regex_match to match two strings. It returns
3504 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3506 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Imported GNU regex to the soruce tree into lib/contrib.
3509 Fixed some compiler warning from the regex.c.
3511 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Fixed MOTD command in the server to work in router environment.
3515 * Fixed the MOTD command in the client library to support
3516 the server argument in the command.
3518 * Added `nickname_len' argument to the silc_idlist_add_client
3519 in the server, as the `nickname' argument may be binary data
3522 * Added silc_idlist_get_channels to return all channels from
3525 * Implemented LIST command to the server. Affected file is
3528 * Implemented the LIST command to the client library and on the
3531 * Added [<user count>] argument to the LIST command reply.
3532 With private channels the user count is not shown.
3534 * Updated TODO and README.
3536 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * The client entry's data.registered must be TRUE even with
3539 global client entry on global client list. The data.registered
3540 is used to check whether the client is anymore in the network,
3541 for example with WHOWAS command so it must be valid.
3543 * Fixed the WHOWAS command in the server. It now actually works
3544 in router environment. Added function into silcd/command_reply.c
3545 silc_server_command_reply_whowas_save.
3547 * Added silc_idlist_purge function to the silcd/idlist.c
3548 to periodically purge the ID Cache.
3550 * Fixed INFO command in the server. It works now in router
3551 environment. Added <server name> argument to the INFO command
3552 reply. Updated the protocol specs.
3554 * Fixed minor bug in silc_idcache_purge to not purge if the
3555 expire value is zero.
3557 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3558 they were buggy because of the WHOWAS information.
3560 * Fixed local command MSG to handle the async resolving of
3561 the remote client properly. It used to fail the first MSG.
3562 Affected file silc/local_command.c.
3564 * Added `data_len' field to SilcIDCache context.
3566 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Update TODO. Todo in commands in the server.
3570 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3573 used by routers as broadcast packet to inform other routers
3574 about the changed user mode.
3576 Implemented the notify handling in the server. Affected file is
3577 silcd/packet_receive.c. Added the function
3578 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3580 * Added new generic Channel Payload and deprecated the New Channel
3581 Payload. The New Channel Payload is now the generic Channel
3584 * Added new argument `mode' to the silc_server_send_new_channel
3585 as it is required in the Channel Payload now.
3587 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3588 and created a new and real SilChannelPayload to represent the
3589 new generic Channel Payload. Implemented the encode/decode
3590 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3592 * Added silc_server_get_client_channel_list to return the list
3593 of channels the client has joined for WHOIS command reply.
3594 Affected file silcd/server.[ch].
3596 * Implemented the channel list sending in the WHOIS command reply
3597 in server and in the client.
3599 Implemented the channel list displaying on the user interface
3600 as well. Affected file silc/client_ops.c.
3602 * Added silc_channel_payload_parse_list to parse list of Channel
3603 Payloads. It returns SilcDList list of SilcChannelPayloads.
3604 Client for example can use this function to parse the list of
3605 channels it receives in the WHOIS command reply. The caller
3606 must free the list by calling silc_channel_payload_list_free.
3607 Affected files lib/silccore/silcchannel.[ch].
3609 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Added one new argument <user mode> to the WHOIS command reply
3612 to return the mode of the user in SILC. Updated the protocol
3615 Implemented it to the server and client.
3617 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Fixed the mode printing on the user interface on joining.
3620 Affected file silc/client_ops.c.
3622 * Implemented the UMODE command and user modes in general to the
3623 client library and to the user interface.
3625 * Implemented the UMODE command to the server.
3627 * The server now sends UNKNOWN_COMMAND error status if client sends
3628 unknown command. Affected file silcd/command.c.
3630 * All server commands now handle the command identifier the right
3631 way when sending the command reply to the client. The client can
3632 use to identify the command replies with the identifier.
3634 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Added silc_server_get_client_route to resolve the route to
3637 the client indicated by the client ID. Affected file is
3640 * Added silc_server_relay_packet as general function to relay
3641 packet to arbitrary destination. This deprecates functions
3642 like _send_private_message_key, _relay_notify etc. Affected
3643 file is silcd/packet_send.[ch].
3645 Removed silc_server_send_key_agreement,
3646 silc_server_send_private_message_key and
3647 silc_server_packet_relay_notify functions from the file
3648 silcd/packet_send.[ch].
3652 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3653 server. Affected file silcd/packet_receive.[ch].
3655 * Implemented the KILL command to the client. Implemented the
3656 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3657 Affected files lib/silcclient/command[_reply].c and
3658 lib/silcclient/client_notify.c. Implemented the KILL notify
3659 printing in the user inteface.
3661 * Fixed a lot silc_parse_nick memory leaks from the client
3662 library in the file lib/silcclient/command.c.
3664 * Changed the silc_server_send_notify_on_channels's `sender'
3665 argument from SilcSocketConnection to SilcClientEntry to
3666 check the sender as entry and not as connection object and not
3667 to send to the client provided as argument. The affected file
3668 is silcd/packet_send.[ch].
3670 * The notify packets that are destined directly to the client used
3671 to not to be processed by the server. Now changed that and the
3672 server processes all notify packets. After relaying the packet
3673 to the client the notify packet is processed in the server.
3675 * The silc_server_free_client_data now checks whether there is
3676 pending outgoing traffic for the client and purges the data to
3677 the network before removing the client entry.
3679 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3682 an client is killed from the SILC Network. Updated the protocol
3685 Added new function silc_server_send_notify_killed to the
3686 silcd/packet_send.[ch].
3688 * Added function silc_server_packet_relay_notify to relay notify
3689 packets that are destined directly to a client. In this case
3690 the server does not process the notify packets but merely relays
3691 it to the client. Affected file silcd/packet_send.[ch].
3693 Added also silc_server_packet_process_relay_notify to check
3694 whereto relay the notify. Affected file is
3695 silcd/packet_receive.[ch].
3697 * Implemented the KILL command to the server.
3701 * Added the backup schema desgined last fall to the protocol
3702 specs for everyone to see. The specification is in the
3703 *-spec-xx.txt draft and the packet type definitions for the
3704 backup routers is in *-pp-xx.txt draft. Thusly, added also
3705 new packet type SILC_PACKET_CELL_ROUTERS.
3707 * A big security problem in the implementation discovered. The
3708 signoff of an client did not cause new channel key generation
3709 which it of course should've done. The channel keys must be
3710 always re-generated when client leaves (or signoffs) the channel.
3711 The silc_server_remove_from_channels funtion now handles
3712 the channel key re-generation.
3714 * Added `sender' argument to the silc_server_send_notify_on_channels
3715 to not to send the client provided as argument. Affected file
3716 silcd/packet_send.[ch].
3718 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Implemented OPER and SILCOPER commands into the server and
3723 * Added silc_auth_verify and silc_auth_verify_data to verify
3724 the authentication directly from the authentication payload.
3725 It supports verifying both passphrase and public key based
3726 authentication. Affected file lib/silccore/silcauth.[ch].
3728 * Added `hash' field to the SilcIDListData structure. It is the
3729 hash negotiated in the SKE protocol. Affected file is
3732 * Slight redesigning of the SilcAuthPayload handling routines.
3733 Do not send SilcPKCS but SilcPublicKey as argument.
3735 * Implemented the public key authentication support to the
3736 serverconfig. The public key is loaded from the provided path
3737 and saved as authentication data to void * pointer. Thus,
3738 changed the unsigned char *auth_data to void *auth_data;
3740 * Fixed SHUTDOWN command to send the reply before the server
3741 is shutdown. :) Affected file silcd/command.c.
3743 * Fixed fatal bug in CONNECT command. The hostname was invalid
3744 memory and server crashed. Affected file silcd/command.c.
3746 * Fixed fatal bug in CLOSE command. The server_entry became
3747 invalid but was referenced later in the command. Affected file
3750 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Fixed fatal bug in failure packet handling. Server ignored
3753 the failure and thus crashed when it came.
3757 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3760 that the command may be executed only once in (about) 2 seconds.
3761 The old SILC_CF_LAG flag is same but allows command bursts up
3762 to five before limiting.
3764 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3765 server code. Various commands now includes the CF_LAG_STRICT
3766 flag to disallow any kind of miss-use of the command.
3768 * Fixed the silc_buffer_unformat to not to allocate any data
3769 if the length of the data is zero. It used to allocate the
3770 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3772 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Changed the format of AdminConnection configuration section
3775 in the server. Added username of the admin to the format.
3776 Affected files silcd/serverconfig.[ch].
3778 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3779 to return admin configuration data by host, username and/or
3782 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Implemented WHOWAS command to the server. Added the functions:
3786 silc_server_command_whowas_parse,
3787 silc_server_command_whowas_send_reply,
3788 silc_server_command_whowas_from_client and
3789 silc_server_command_whowas_from_server
3791 * Added <Client ID> argument to the WHOWAS command reply. Updated
3792 the protocol specs accordingly.
3794 * Implemented WHOWAS command and command_reply to the client
3797 Implemented the WHOWAS printing on the user interface.
3799 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Added new argument to the WHOWAS command reply, the real name.
3802 It is an optional argument. Updated the protocol specs.
3804 * Added SilcIDCacheDestructor callback that is registered when
3805 the SilcIDCache is allocated. The callback is called when
3806 an cache entry in the ID Cache expires, or is purged from the
3807 cache. Added into lib/silccore/idcache.[ch].
3809 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3810 to destruct the client entries when the cache entry expires.
3811 Other ID Cache's in server and in the client library ignores
3814 * If the ID Cache entry's `expire' field is zero then the entry
3815 never expires. Added boolean `expire' argument to the
3816 silc_idcache_add function in the lib/silccore/idcache.[ch].
3817 If it is TRUE the default expiry value is used.
3819 * Added silc_server_free_client_data_timeout that is registered
3820 when client disconnects. By default for 5 minutes we preserve
3821 the client entry for history - for WHOWAS command.
3823 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Added support to the server to enforce that commands are not
3826 executed more than once in 2 seconds. If server receives
3827 commands from client more frequently, timeout is registered
3828 to process the commands. Affected file silcd/command.c.
3829 Added new function silc_server_command_process_timeout.
3831 * Changed NICK_NOTIFY handling in client library to check that
3832 if the client's nickname was changed, so there is no need to
3833 resolve anything from the server.
3835 * Removed error printing from the WHOIS and IDENTIFY commands.
3836 If error occurs then it is ignored silently in the client library.
3837 The application, however, may map the received error to
3838 human readable error string. The application currently maps
3839 the NO_SUCH_NICKNAME error to string.
3841 * Made the command status message public to the application. Moved
3842 them from lib/silcclient/command_reply.c to
3843 lib/silcclient/command_reply.h. The application can map the
3844 received command status to the string with the
3845 silc_client_command_status_message function.
3847 * Added check to the server to check that client's ID is same
3848 as the Source ID in the packet the client sent. They must
3851 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Added dist-bzip hook to the Makefile.am to make bzip2
3854 compressed distributions.
3856 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Server now enforces the maximum length for the nickname and
3859 the channel as protocol specification dictates. 128 bytes for
3860 nickname and 256 bytes for channel name.
3862 * Moved the WHOIS printing to the application. The client libary
3863 does not print out the WHOIS information anymore, the application
3864 must do it. Renamed silc_client_command_reply_whois_print to
3865 the silc_client_command_reply_whois_save.
3867 The client's idle time is also sent to the application now, and
3868 the idle is shown on screen.
3870 * Added silc_client_command_reply_identify_save to save the
3871 received IDENTIFY entries.
3873 * Do not check for channel private keys in message sending and
3874 reception if the channel does not have the PRIVKEY mode set.
3875 Affected file lib/silclient/client_channel.c.
3877 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3880 just surfaced after chaning the JOIN procedure.
3882 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Added silc_client_get_clients_by_list to get client entries
3885 from Client ID list, that is returned for example by JOIN
3886 and USERS command replies. The application should use this
3887 function for example when JOIN command reply is received to
3888 resolve the clients already on the channel (library does not
3889 do that anymore as USERS command reply is not used in the JOIN
3890 procedure anymore). Affected files lib/silcclient/silcapi.h and
3891 lib/silcclient/idlist.c.
3893 * JOIN command reply and USERS command reply returns now SilcBuffer
3894 pointers instead of unsigned char pointers when returning
3895 the client list and mode list.
3897 * Added <Client ID> argument to the JOIN command reply, mainly
3898 for the server to identify for which client the command was
3899 originally sent. Updated protocol specs accordingly.
3901 * Added SilcDlist private_key pointer to the SilcChannelEntry
3902 in the client to support the channel private keys. Affected
3903 file is lib/silcclient/idlist.h.
3905 * Added SilcChannelPrivateKey argument to the function
3906 silc_client_send_channel_message so that application can choose
3907 to use specific private ke if it wants to. If it is not provided,
3908 the normal channel key is used, unless private keys are set.
3909 In this case the first (key that was added first) is used
3910 as the encryption key.
3912 * Implemented the support for channel private key handling.
3913 Implemented the following functions:
3915 silc_client_add_channel_private_key,
3916 silc_client_del_channel_private_keys,
3917 silc_client_del_channel_private_key,
3918 silc_client_list_channel_private_keys and
3919 silc_client_free_channel_private_keys
3921 Affected file lib/silcclient/client_channel.c.
3923 * Added the support for the private keys in the channel message
3924 sending and encryption and in the message reception and
3925 decryption. Affected funtions are
3926 silc_client_send_channel_message and silc_client_channel_message.
3928 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Added SKE's key verify callback to the client library's
3931 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3933 * Removed the statement that server (or router) must send USERS
3934 command reply when joining to the channel so that the client
3935 knows who are on the channel. Instead, the client list and
3936 client's mode list is now sent in the JOIN command reply to the
3937 client who joined channel. This is better solution.
3939 * Added function silc_server_get_users_on_channel and function
3940 silc_server_save_users_on_channel to the silcd/server.[ch].
3942 * Removed function silc_server_command_send_users from the
3945 * Do not show topic on the client library anymore. The topic is
3946 sent in the command reply notify to the application and the
3947 application must show the topic now.
3949 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Added client searching by nickname hash into the IDENTIFY and
3952 WHOIS commands in the server as they were clearly missing from
3953 them. Affected file is silcd/command.c.
3955 * Fixed a bug in private message receiving in the client library.
3956 The remote ID was freed and it wasn't supposed, now it is
3959 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Minor fix to the channel payload; allocate the data area, as it
3962 needs to be of specific length.
3964 * If the key agreement port is zero then the operating
3965 system will define the bound port. Affected files are
3966 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3968 * Added new function silc_channel_payload_decrypt into the file
3969 lib/silccore/silcchannel.[ch].
3971 * Moved the channel message etc, check from silc_packet_decrypt
3972 to applications. The library calls now a generic
3973 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3974 when the packet is either normal or special. This was done to
3975 allow more wide range of checking that was not allowed when
3976 the code was in library. Now applications can do virtually any
3977 checks to the packet and return to the library the decision how
3978 the packet should be processed. Affected files are
3979 lib/silccore/silcpacket.[ch].
3981 Added silc_server_packet_decrypt_check to the server and
3982 silc_client_packet_decrypt_check to the client library.
3984 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3985 to send with specified source and destination information.
3987 * Channel message delivery between routers was broken after the
3988 channel key distribution was fixed earlier. The channel key
3989 was used be to distributed to other routers as well which is not
3990 allowed by the protocol. Now this is fixed and channel keys
3991 really are cell specific and the channel message delivery between
3992 routers comply with the protocol specification.
3994 * Fixed various commands in server to check also the global list
3995 for the channel entry and not just the local list. The affected
3996 file silcd/command.c.
3998 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Added assert()s to buffer formatting and unformatting routines
4001 to assert (if --enable-debug) when error occurs. Affected
4002 file: lib/silcutil/silcbuffmt.c.
4004 * Changed to auto-reconnect to check whether the remote host is
4005 router and register the re-connect timeout if it is. It used
4006 to check that whether we are normal server, but router must do
4007 auto-reconnect with another router as well. Affected file
4010 * Removed the [<key len>] option from CMODE command as the cipher
4011 name decides the key length, nowadays. See the defined ciphers
4012 from the protocol specification.
4014 * Added [<hmac>] option to the CMODE command to define the HMAC
4015 for the channel. Added SILC_CMODE_HMAC channel mode.
4017 * Added [<hmac>] option for the JOIN command so that user can
4018 select which HMAC is used to compute the MACs of the channel
4021 * Added Hmac field to the Channel Message Payload. The integrity
4022 of plaintext channel messages are now protected by computing
4023 MAC of the message and attaching the MAC to the payload. The
4024 MAC is encrypted. Now, it is clear that this causes some
4025 overhead to the size of the packet but rationale for this is that
4026 now the receiver can verify whether the channel message decrypted
4027 correctly and also when private keys are set for the channel the
4028 receiver can decrypt the packet with several keys and check from
4029 the MAC which key decrypted the message correctly.
4031 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4032 lib/silccrypt/silccipher.[ch].
4034 * Added silc_hash_len to return the digest length into the
4035 lib/silcrypt/silchash.[ch].
4037 * Rewrote parts of Silc Channel Payload interface in the
4038 lib/silccore/silcchannel.[ch]. The encode function now also
4039 encrypts the packet and parse function decrypts it.
4041 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Fixed a minor formatting bug in the SKE's key material processing.
4044 It actually might have processed the keys wrong way resulting
4047 * Redefined the mandatory HMAC algorithms and added new algorithms.
4048 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4049 and hmac-md5 truncated to 96 bits. The mandatory is now
4050 hmac-sha1-96. Rest are optional (including the one that used
4051 to be mandatory). Rationale for this is that the truncated HMAC
4052 length is sufficient from security point of view and can actually
4053 make the attack against the HMAC harder. Also, the truncated
4054 HMAC causes less overhead to the packets. See the RFC2104 for
4057 * Added new [hmac] configuration section. The SKE used to use
4058 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4059 is of course wrong. The official names that must be proposed in
4060 the SKE are the ones defined in the protocol specification
4061 (hmac-sha1-96 for example). The user can configure any hmac
4062 using any hash function configured in the [hash] section. At
4063 least, the mandatory must be configured.
4065 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4067 * Added HMAC list to the SKE proposal list. It has now both
4068 hash algorithm list and HMAC list. This makes the protocol
4069 incompatible with previous versions. The SKE now seems to work
4070 the way it is supposed to work, for the first time actually.
4072 * Defined plain Hash algorithms to the protocol specification.
4075 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Implemented support for key agreement packets into the server.
4078 Added functions silc_server_key_agreement and
4079 silc_server_send_key_agreement. Other than these functions,
4080 server has nothing to do with this packet.
4082 * Added support for private message key packets into the server.
4083 Added functions silc_server_private_message_key and
4084 silc_server_send_private_message_key.
4088 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4089 called in the protocol's final callback instead in the END
4090 protocol state. This makes a little more sense and in the same
4091 time in client we can use the same protocol routines for normal
4092 key exchange and to key agreement packet handling as well.
4094 * Added to both client's and server's KE protocol context the
4095 SilcSKEKeyMaterial pointer to save the key material. We will
4096 bring the key material to the protocol's final callback by doing
4097 this. The final callback must free the key material.
4099 * Added SKE's packet_send callback into client's KE protocol
4100 context so that the caller can choose what packet sending function
4101 is used. This way we can use different packet sending when
4102 doing normal SKE when doing key agreement packet handling (in
4103 the key agreement packet handling we do not want to encrypt
4106 * Implemented the responder side of the key agreement routines
4107 in the client. The client can now bind to specified port and
4108 accept incoming key negotiation. The key material is passed
4109 to the application after the protocol is over.
4111 * Implemented the processing of incoming Key Agreement packet
4112 in the client. Added function silc_client_key_agreement to
4115 * Implemented the intiator side of the key agreement routines
4116 in the client. The client can now initiate key agreement with
4117 another remote client. The key material is passed to the
4118 application after the protocol is over.
4120 * Created client_keyagr.c to include all the key agreement
4123 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4124 SILC_TASK_CALLBACK except that it is not static.
4126 * Created client_notify.c and moved the Notify packet handling
4127 from the client.[ch] into that file.
4129 * Created client_prvmsg.c and moved all private message and
4130 private message key routines from the client.[ch] into that file.
4132 * Create client_channel.c and moved all channel message and
4133 channel private key routines from the client.[ch] into that file.
4135 * Changed silc_client_get_client_by_id_resolve to resolve with
4136 WHOIS command instead of IDENTIFY command, in the file
4137 lib/silclient/idlist.c.
4139 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Implemented the SKE's responder side to the Client library.
4143 * When FAILURE is received to the protocol do not trust it
4144 blindly. Register a timeout to wait whether the remote closes
4145 the connection as it should do it, only after that process the
4146 actual failure. This was changed to both client and server.
4148 * Added client_internal.h to include some of the structures
4149 there instead of client.h in lib/silcclient/.
4151 * Added function silc_task_unregister_by_callback to unregister
4152 timeouts by the callback function.
4154 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Some "Incomplete WHOIS info" errors has been appearing on the
4157 log files. Took away the entry->userinfo check from WHOIS
4158 reply sending. The entry->userinfo is now " " if client did not
4159 provide one. I thought this was fixed earlier but something
4160 is wrong still. Let's see if the error still appears.
4162 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Fixed a minor bug in the login when the channel key is
4165 re-generated in the server. It used to generate the key in
4166 wrong order and thus caused problems in the channel traffic.
4168 * Fixed a minor bug in channel key distsribution after
4169 KICK command. The key was not sent to the router even though
4172 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Added silc_ske_process_key_material_data as generic routine
4175 to process any key material as the SILC protocol dictates. The
4176 function is used by the actual SKE library but can be used by
4177 applications as well. This relates to the private message keys
4178 and the channel private keys since they must be processed the
4179 same way the normal SILC session keys. The protocol dictates
4180 this. Affected files: lib/silcske/silcske.[ch].
4182 Added also silc_ske_free_key_material to free the
4183 SilcSKEKeyMaterial structure.
4185 * Defined silc_cipher_set_key function to set the key for
4186 cipher without using the object's method function. The affected
4187 files: lib/silccrypt/silccipher.[ch].
4189 * Implemented silc silc_client_add_private_message_key,
4190 silc_client_add_private_message_key_ske,
4191 silc_client_del_private_message_key,
4192 silc_client_list_private_message_keys and
4193 silc_client_free_private_message_keys functions in the
4196 Added functions silc_client_send_private_message_key to send
4197 the Private Message Key payload and silc_client_private_message_key
4198 to handle incoming Private Message Key payload.
4200 * Added Cipher field to the Private Message Key payload to set
4201 the cipher to be used. If ignored, the default cipher defined
4202 in the SILC protocol (aes-256-cbc) is used.
4204 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Removed lib/silcclient/ops.h file.
4208 Redefined parts of the SILC Client Library API. Created new
4209 file silcapi.h that deprecates the ops.h file and defines the
4210 published Client Library API. Defined also private message key
4211 API and channel private key API into the file.
4213 This is the file that the application must include from the
4214 SILC Client Library. Other files need not be included by
4215 the application anymore.
4217 * Added new key_agreement client operation callback and also
4218 defined the Key Agreement library API for the application.
4220 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4223 is used by clients to request key negotiation between another
4224 client in the SILC network. If the negotiation is started it
4225 is performed using the SKE protocol. The result of the
4226 negotiation, the secret key material, can be used for example
4227 as private message key.
4229 Implemented the Key Agreement payload into the files
4230 lib/silccore/silauth.[ch].
4232 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Redefined ciphers for the SILC protocol. Added some new ciphers
4235 and defined the key lengths for the algorithms. Changed the
4236 code accordingly. The default key length is now 256 bits.
4238 * Fixed SKE key distribution function silc_ske_process_key_material
4239 when the key length is more than 128 bits. The default key
4240 length in SILC is now 256 bits.
4242 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4243 to indicate unsupported algorithm.
4245 * Renamed rijndael.c to aes.c and all functions as well.
4247 * Fixed a long standing channel key setting bug in client library.
4248 Weird that it has never surfaced before.
4250 * Fixed bug in channel deletion. If the entire channel is removed
4251 then it must also delete the references of the channel entry
4252 from the client's channel list as the client's channel entry and
4253 the channel's client entry share same memory.
4255 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Implemented CONNECT and SHUTDOWN commands in the client.
4259 * Implemented CLOSE command to the client.
4261 * Added the function silc_idlist_find_server_by_name into the
4262 files silcd/idlist.[ch].
4264 Added the function silc_idlist_find_server_by_conn into the
4265 files silcd/idlist.[ch].
4267 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * DIE command was renamed to SHUTDOWN. Updated the both code
4272 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4273 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4275 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4278 * Added function silc_server_create_connection function to create
4279 connection to remote router. My server implementation actually
4280 does not allow router to connect to normal server (it expects
4281 that normal server always initiates the connection to the router)
4282 so the CONNECT command is only good for connecting to another
4285 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4288 or some other client was kicked from the channel.
4290 Implemented the handling of the notify type to both client
4293 Implemented silc_server_send_notify_kicked to send the KICKED
4294 notify. It is used to send it to the server's primary router.
4296 * Implemented the KICK command into server and client.
4298 * Added `query' argument to the silc_idlist_get_client function
4299 to indicate whether to query the client from server or not if
4302 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4303 to indicate that the client is not channel founder.
4307 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Removed the rng context from SilcPacketContext structure and
4310 changed that the packet routine uses the Global RNG API.
4312 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Added support for quit message that client can "leave" on the
4315 channel when it quits the SILC. It is ditributed inside the
4316 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4318 Added silc_server_free_client_data that will take the
4319 signoff message as argument.
4321 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4323 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Updated parts of the protocol specification to keep it up
4328 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4331 payloads in one packet.
4333 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4334 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4335 use now the new List flag.
4337 * Also deprecated the following packet types: REPLACE_ID,
4338 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4340 * Added list support for Notify packet in server.
4342 * Added silc_server_send_notify_channel_change to send the
4343 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4344 the silc_server_send_replace_id.
4346 * Added silc_server_send_notify_nick_change to send the
4347 NICK_CHANGE notify type. Deprecates the function
4348 silc_server_send_replace_id.
4350 * Added silc_server_send_notify_join to send the JOIN notify type.
4351 Deprecates the function silc_server_send_new_channel_user.
4353 * Added silc_server_send_notify_leave to send LEAVE notify type.
4354 Deprecates the function silc_server_send_remove_channel_user.
4356 * Added silc_server_send_notify_cmode and
4357 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4358 types. Deprecates the silc_server_send_set_mode function.
4360 * Added SERVER_SIGNOFF notify type to indicate that server has
4361 quit. This means that all clients on the channel from that
4362 server will drop. This can be also used when netsplit happens.
4364 Deprecated REMOVE_ID packet type since it is not needed anymore
4367 Added silc_server_send_notify_server_signoff to send the
4368 SERVER_SIGNOFF notify type. Deprecates the function
4369 silc_server_send_remove_id.
4371 Added also silc_server_send_notify_signoff to send the
4372 SIGNOFF notify type.
4374 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4375 SILC protocol from this day on. Changed the protocol
4376 specification as well.
4378 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4379 notify type. It is used between routers to notify about
4380 topic changes on a channel.
4382 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4385 * Partly updated the protocol specification to comply with the
4386 changes now made. It is still though a bit outdated.
4388 * The JOIN notify type now takes one extra argument <Channel ID>.
4389 The packet used to be destined to the channel but now the
4390 JOIN type may be sent as list thus it is impossible to
4391 destine it to any specific channel. By adding this argument
4392 it is again possible.
4394 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Added CREDITS file. The CHANGES and CREDITS file will appear
4397 in the distribution as well.
4399 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4402 types in the server's silcd/packet_receive.c.
4404 * Implemented CMODE and CUMODE to work in router environment.
4406 * Fixed minor encoding and decoding buglet from the
4407 lib/silccore/silcmode.c.
4409 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4412 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4414 * Changed all SilcConfigServer* and silc_config_server* to
4415 SilcServerConfig* and silc_server_config*, respectively.
4418 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Associated the ID (client or server ID) to the Authentication
4421 Payload to avoid any possibility of forging. Updated the
4422 protocol specification and the code accordingly.
4424 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * The RSA key length is now save to the RsaKey context in the
4427 key generation process in lib/silccrypt/rsa.c. The key length
4428 is now used to figure out the maximum size of the block allowed
4429 to be encrypted/signed.
4431 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4432 is equivalent to the silc_mp_mp2bin but does not allocate any
4435 * Changed silc_mp_mp2bin API to take length argument. If it is
4436 non-zero then the buffer is allocated that large. If zero, then
4437 the size is approximated using silc_mp_sizeinbase, which however
4440 * Created Global RNG API which is global RNG that application can
4441 initialize. After initializing, any routine anywhere in the
4442 code (including library) can use RNG without allocating a new
4443 RNG object. This was done to allow this sort of use of the
4444 RNG in code that has no chance to allocate RNG object. All
4445 applications currently allocate this and many routines in the
4446 library use this. Affected file lib/silccrypt/silcrng.[ch].
4448 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4449 it to use the Global RNG API.
4451 * Defined Authentication Payload into protocol specification that
4452 is used during SILC session to authenticate entities. It is
4453 used for example by client to authenticate itself to the server
4454 to obtain server operator privileges.
4456 Implemented this payload into the lib/silccore/silcauth.[ch].
4457 Implemented also routines for public key based authentication
4458 as the new protocol specification dictates.
4460 Moved definitions of different authentication methods from
4461 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4463 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4464 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4465 silc_pkcs_verify_with_hash functions into the file
4466 lib/silccrypt/silcpkcs.[ch].
4468 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * The client entry's userinfo pointer must be always valid.
4471 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4472 will fail since it requires the userinfo. Now, the userinfo
4473 is allocated as "" if actual userinfo does not exist. Actually,
4474 it must exist and it is totally Ok to drop client connections
4475 that does not announce the userinfo. However, we will make
4476 this workaround for now.
4478 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4479 to return the remote port by socket.
4481 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4484 SILC_SERVER_PENDING_EXEC and added an new macro
4485 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4486 data or when error occurs while processing the pending command.
4488 Added new argument `destructor' into silc_server_command_pending
4489 and to the SilcServerCommandPending object. This destructor is
4490 now called after calling the pending callback or if error occurs
4491 immediately. If error occurs the actual pending callback won't
4492 be called at all - only the destructor. The destructor may be
4493 NULL if destructor is not needed.
4495 All this applies for client library code as well. Similar
4496 changes were made there as well for the pending commands.
4498 In the client, the application must now allocate the
4499 SilcClientCommandContext with the silc_client_command_alloc
4502 * Added reference counter to the SilcServerCommandContext. Added
4503 function silc_server_command_alloc and silc_server_command_dup
4506 Same type of functions added to the client library for the same
4509 * Removed the cmd_ident from IDListData away since it is now
4510 global for all connections. It is the command identifier used
4511 in command sending and with pending commands. The affected file
4514 * Added reference counter to the SilcSocketConnection objecet to
4515 indicate the usage count of the object. The object won't be
4516 freed untill the reference counter hits zero. Currently only
4517 server uses this, and client ignores it. The client must be
4518 set to use this too later. The affected files are
4519 lib/silccore/silcsockconn.[ch]. Added also the function
4520 silc_socket_dup to increase the reference counter.
4522 This was mainly added because it is possible that the socket
4523 is removed underneath of pending command or other async
4524 operation. Now it won't be free'd and proper DISCONNECTING
4525 flags, etc. can be set to avoid sending data to connection that
4526 is not valid anymore.
4528 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4529 the connection. After that it sets SILC_SET_DISCONNECTED.
4530 It is, however, possible that the socket data is not still freed.
4531 The silc_server_packet_process now checks that data is not
4532 read or written to connection that is DISCONNECTED. The socket
4533 get's freed when the reference counter hits zero.
4535 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Changed the client operation API: channel_message operation's
4538 `sender' is now the client entry of the sender, not the nickname
4539 and the `channel' is the channel entry, not the channel name.
4541 In the private_message operation the `sender' is now also the
4542 client entry of the sender not the nickname.
4544 Affected file is lib/silcclient/ops.h and all applications
4545 using the client operations.
4547 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Moved the calling of ops->connect() from connect_to_server_final
4550 into receive_new_id functin since that is the point when the
4551 client is actually allowed to send traffic to network. The
4552 affected file is lib/silcclient/client.c.
4554 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4557 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4558 (if needs broadcasting) instead of broadcasting the packets one
4559 by one which would make a burst in the network traffic.
4561 * Added `broadcast' argument to the functions in silcd/server.[ch]
4562 silc_server_create_new_channel[_with_id] to indicate whether
4563 to send New Channel packet to primary router.
4565 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added new function into the silcd/server.[ch] files:
4568 silc_server_create_new_channel_with_id to create new channel with
4569 already existing Channel ID.
4571 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4572 lib/silccore/silcpacket.h. This packet is used t send list of
4573 Set Mode payloads inside one packet. Server uses this to set
4574 the modes for the channels and clients on those channels, that it
4575 announced to the router when it connected to it. The protocol
4576 specification has been updated accordingly.
4578 * The silc_server_new_channel did not handle the packet coming
4579 from normal server as it normally does not send that. However,
4580 when it announces its channels it does send it. Implemented
4581 the support for that.
4583 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4584 into the file lib/silccore/id.h.
4586 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Fixed memory leaks in the functions silc_idlist_del_client,
4589 silc_idlist_del_channel and silc_idlist_del_server in the file
4590 silcd/idlist.c. All of those leaked like a sieve.
4592 * Fixed some small memory leaks in the client's function
4593 silc_client_notify_by_server.
4595 * Added functions into silcd/server.c: silc_server_announce_clients,
4596 silc_server_announce_channels and silc_server_announce_server.
4597 These functions are used by normal and router server to announce
4598 to its primary router about clients, channels and servers (when
4599 router) that we own. This is done after we've connected to the
4602 These functions effectively implements the following packet types:
4603 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4604 and SILC_PACKET_NEW_ID_LIST.
4606 * Added new functions into the silcd/packet_receive.[ch]:
4607 silc_server_new_id_list, silc_server_new_channel_list and
4608 silc_server_new_channel_user_list to handle the incoming
4609 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4611 * Added support of changing Channel ID in the function
4612 silc_server_replace_id. If the server that announces a channel
4613 to the router already exists in the router (with same name but
4614 with different Channel ID), router is responsible to send
4615 Replace ID packet to the server and force the server to change
4616 the Channel ID to the one router has.
4618 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4619 client that the Channel ID has been changed by the router. The
4620 normal server sends this to the client. Client must start using
4621 the new Channel ID as the channel's ID.
4623 Implemented handling of this new type into lib/silcclient/client.c
4624 into the function silc_client_notify_by_server.
4626 * Added new function silc_idlist_replace_channel_id into the files
4627 silcd/idlist.[ch] to replace the Channel ID.
4629 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Call silc_server_command_identify_check always when processing
4632 the IDENTIFY command in silcd/command.c
4634 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4637 send keepalive packets. The packet can be sent by clients,
4638 servers and routers.
4640 Added function silc_socket_set_heartbeat into the file
4641 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4642 If not set, the heartbeat is not performed. The actual
4643 heartbeat is implemented in the low level socket connection
4644 library. However, application is responsible of actually
4647 Added silc_server_send_heartbeat to send the actual heartbeat
4648 packet into silcd/packet_send.[ch]. Server now performs
4649 keepalive with all connections.
4651 * Added silc_task_get_first function into lib/silcutil/silctask.c
4652 to return the timeout task with shortest timeout. There was a bug
4653 in task unregistration that caused problems. TODO has been
4654 updated to include that task system must be rewritten.
4656 * The client library will now resolve the client information when
4657 receiving JOIN notify from server for client that we know but
4658 have incomplete information.
4660 * Rewrote parts of silc_server_remove_from_channels and
4661 silc_server_remove_from_one_channel as they did not remove the
4662 channel in some circumstances even though they should've.
4664 * Encryption problem encountered in server:
4666 The LEAVE command used to send the Channel Key packet to the
4667 router immediately after generating it. However, the code
4668 had earlier sent Remove Channel user packet but not immediately,
4669 ie. it was put to queue. The order of packets in the router
4670 was that Channel Key packet was first and Remove Channel User
4671 packet was second, even though they were encrypted in the
4672 reverse order. For this reason, MAC check failed. Now, this
4673 is fixed by not sending the Channel Key packet immediately but
4674 putting it to queue. However, this is more fundamental problem:
4675 packets that are in queue should actually not be encrypted
4676 because packets that are sent immediately gets encrypted
4677 actually with wrong IV (and thus MAC check fails). So, packets
4678 that are in queue should be encrypted when they are sent to
4679 the wire and not when they put to the queue.
4681 However, the problem is that the current system has not been
4682 designed to work that way. Instead, the packet is encrypted
4683 as soon as possible and left to the queue. The queue is then
4684 just purged into wire. There won't be any fixes for this
4685 any time soon. So, the current semantic for packet sending
4688 o If you send packet to remote host and do not force the send
4689 (the packet will be in queue) then all subsequent packets to the
4690 same remote host must also be put to the queue. Only after the
4691 queue has been purged is it safe again to force the packet
4694 o If you send all packets immediately then it safe to send
4695 any of subsequent packets through the queue, however, after
4696 the first packet is put to queue then any subsequent packets
4697 must also be put to the queue.
4699 Follow these rules and everything works fine.
4701 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added new function silc_server_remove_clients_by_server to
4704 remove all client entries from ID list when the server connection
4705 is lost. In this case it is also important to invalidate all
4706 client entires as they hold the invalid server entry. This
4707 fixes fatal bug when server has lost connection and will reconnect
4710 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Made some sanity checks to silc_server_daemonise like to check
4713 whether the requested user and group actually exists.
4715 * Added sanity check to SKE's silc_ske_responder_finish to check
4716 that the public and private key actually is valid.
4718 * Invalidate the client's nickname when receiving Replace ID
4719 packet and the Client ID is being replaced. This means that the
4720 server will query the nickname if someone needs it (client)
4723 * Sort the ID Cache in client library when the ID Cache data
4724 has changed (needs sorting).
4726 * Do not allow for SILC client to create several connections to
4727 several servers. The client does not support windows right now
4728 and generating multiple connections causes weird behaviour.
4730 Irssi-silc client does support windows and can handle several
4731 connections without problems, see: www.irssi.org and SILC plugin.
4733 * Fixed some places where client was added to the IDList. The
4734 rule of thumb is following (in order to get everything right):
4735 If the client is directly connected local client then the
4736 `connection' argument must be set and `router' argument must be
4737 NULL to silc_idlist_add_client function. If the client is not
4738 directly connected client then the `router' argument must
4739 bet set and the `connection' argument must be NULL to the
4740 silc_idlist_add_client function.
4742 * The funtion silc_server_packet_send_local_channel actually did
4743 not check whether the client was locally connected or not. It
4744 does that now. Fixed a bug related to LEAVE command.
4746 * Fixed Remove Channel User payload parsing bug in server's
4747 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4749 * The server's silc_server_save_channel_key now checks also the
4750 global ID list for the channel as it might not be in the local
4751 list. Fixed a bug related to LEAVE command.
4753 * Is this the end of the [<unknown>] buglet that has been lurking
4754 around for a long time? A little for loop fix in server's
4755 silc_server_command_whois_parse that is used by both IDENTIFY
4756 and WHOIS command. At least, this was a clear bug and a cause
4757 of one type of [<unknown>] buglet.
4759 * WHOIS and IDENTIFY commands call the function
4760 silc_server_command_[whois/identify]_check function even if
4761 we are not router server.
4763 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Added --with-gmp configuration option. If set the GMP
4766 is always compiled in the SILC source tree. If not set then
4767 it is checked whether the system has the GMP3 installed. If
4768 it has then the GMP won't be compiled (the system's headers
4769 and library is used), if it doesn't have it then the GMP is
4770 compiled in the SILC source tree.
4772 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Changed RSA private exponent generation to what PKCS #1
4775 suggests. We try to find the smallest possible d by doing
4776 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4777 not security fix but optimization.
4779 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Added new config entry [Identity] to fork the server and run
4782 it as specific user and group. A patch from Bostik.
4784 * Imported Dotconf configuration library into lib/dotconf.
4785 This will be used to create the SILC configuration files later.
4786 It will appear in the distsribution after this commit.
4788 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * A big code auditing weekend happening. Auditing code for
4791 obvious mistakes, bugs and errors. Also, removing any code
4794 Removed files for being obsolete:
4796 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4797 inline in the file lib/silcutil/silcbuffer.h)
4799 o lib/silcutil/silcbufutil.c (the header has inline versions)
4801 Changed code to fix possible error conditions:
4803 o The buffer formatting routines now check that the destination
4804 buffer really has enough space to add the data. This applies for
4805 both buffer formatting and unformatting
4806 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4807 unformatting was changed to accomodate following rules:
4808 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4809 sent to the function while XXX_*STRING will not allocate or copy
4810 the data into the buffer. Instead it sets the pointer from the
4811 buffer into the pointer sent as argument (XXX_*STRING used to
4812 require that the pointer must be allocated already). This change
4813 makes this whole thing a bit more consistent and more optimized
4814 (note that the data returned in the unformatting with XXX_*STRING
4815 must not be freed now). The routines return now -1 on error.
4817 o Tried to find all code that use buffer_format and buffer_unformat
4818 and added return value checking to prevent formatting and
4819 especially unformatting errors and possible subsequent fatal
4822 o Changed ske->x and ske->KEY to mallocated pointers in
4823 lib/silcske/silcske.h. Fixed possible data and memory leak.
4825 o Added return value checking to all *_parse* functions. Fixed
4826 many memory leaks as well.
4828 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4829 so that buffer overflows would not happen. All code now also
4830 checks the return value as it can fail.
4832 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Added reconnection support to server if the normal server looses
4835 its connection to the router (for example if router is rebooted).
4836 The server performs normal reconnection strategy implemented
4837 to the server. Affected file silcd/server.c.
4839 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Added new packet type SILC_PACKET_SET_MODE that is used to
4842 distribute the information about changed modes (for clients,
4843 channels and clients channel modes) to all routers in the
4844 network. Updated the protocol specification accordingly.
4846 Added functions into silcd/packet_send.c and
4847 silcd/packet_receive.c: silc_server_send_set_mode,
4848 silc_server_set_mode.
4850 Added new files silcmode.[ch] into lib/silccore that implements
4851 the encoding and decoding of Set Mode Payload. Added new type
4852 SilcSetModePayload. Moved the definitions of different modes
4853 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4855 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Oops, a little mistake in server's connection authentication
4858 protocol. The protocol is not ended with FAILURE but with
4859 SUCCESS if the authentication is Ok. :) Affected file is
4862 * Implemented NICK_CHANGE notify handling in server in the file
4863 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4864 the local clients on the channel. After the changing nickname
4865 in router environment snhould work and the [<unknown>] nickname
4866 should appear no more.
4868 The silc_server_replace_id function that receives the Replace ID
4869 payload now sends the NICK_CHANGE notify type also in the file
4870 silcd/packet_receive.c
4872 * Changed WHOIS and IDENTIFY command to support the maximum amount
4873 of arguments defined in protocol specs (3328 arguments). This
4874 fixed a bug that caused problems when there were more than three
4877 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added extra parameter, command identifier, to the
4880 silc_client_send_command so that explicit command identifier
4883 Changed that ID list routines uses specific command identifier
4884 when sending WHOIS/IDENTIFY requests to the server so that they
4885 can be identified when the reply comes back.
4887 Affected files lib/silcclient/command.[ch],
4888 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4890 * Added `sender' argument to silc_server_packet_send_to_channel
4891 to indicaet the sender who originally sent the packet to us
4892 that we are now re-sending. Ignored if NULL. Affected file
4893 silcd/packet_send.[ch].
4895 * Added some server statistics support in silcd/server_internal.h
4896 SilcServerStatistics structure and around the server code. Also
4897 send some nice statistics information when client is connecting
4900 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed channel ID decoding in server's JOIN command reply in
4903 silcd/command_reply.c
4905 * Fixed braodcasting of replace ID payload to not to send it if
4906 we are standalone server in silcd/packet_receive.c.
4908 * Fixed all channel message sending routines to not to send
4909 packets to clients that has router set, since they are routed
4910 separately in the same function earlier. Affects file
4911 silcd/packet_send.c and all channel packet sending functions.
4913 * In USERS reply, res_argv[i] are not allocated, the table
4914 is allocated. Thus changed that free the table, not its
4917 * In server's whois_check and identify_check if the client is
4918 locally connected do not send any WHOIS commands - they are not
4921 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Fixed some minor bugs in client when sending WHOIS command. The
4924 arguments was in wrong order.
4926 * Removed statis function add_to_channel from server in
4927 silcd/command.c that was previously used with the joining but
4930 * Tested USERS command in router environment successfully with two
4931 routers, two servers and two clients.
4933 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Reorganized the USERS command and command reply in client library
4936 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4937 When the command is given by user we register a pending command
4938 callback that will reprocess the command after the reply has been
4939 received from the server. When reprocessing the packet we then
4940 display the information. Thus, the USERS information is displayed
4941 now in the command callback instead of in the command reply
4942 callback. The processing of the command is same as previously
4943 when server has sent the command reply in the JOINing process.
4945 * Added to USERS command in silcd/command_reply.c to join the client,
4946 we didn't use to know about, to the channel after we've created
4947 a client entry for it. Also, for clienet we did know already still
4948 check whether it is on the channel or not and add it if not.
4950 * Removed silc_server_command_join_notify as the function and its
4953 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Changed the client's pending command handling to the same as the
4956 server's pending command handling. It is also now possible to
4957 execute command reply functions from other command reply
4958 function as the function callbacks for commands and command
4959 replies are one and same. The pending commands are not static
4960 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4961 in client connection context. Thus, pending commands are server
4962 connection specific as it is convenient.
4964 Changed the function silc_client_command_pending and
4965 silc_client_command_pending_del and added new function
4966 silc_client_command_pending_check. Removed the
4967 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4970 * Added cmd_ident, current command identifier, to the client
4971 connection context in lib/silcclient/client.h to keep track on
4972 command identifiers used in command sending. Client's command reply
4973 function handling now supports the mandatory command identifiers.
4975 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4976 funtions in client to fully support pending command callbacks.
4978 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4979 as one of the arguments to the application in the command reply
4982 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4983 before first releasing SILC but came back. Now it is removed again
4984 and should come back nomore. The FORWARDED flag was used only
4985 by the JOINing procedure by forwarding the command packet to router.
4986 Now, the JOINing procedure has been changed to more generic (due
4987 to various router environment issues) and FORWARDED is not needed
4988 anymore for anything. The protocol specification is yet to be
4991 Now, removed silc_server_packet_forward from server and the flag
4992 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4994 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Renamed NAMES command to USERS command. The NAMES was named that
4997 due to historical reasons. Now it is renamed. Also, rewrote
4998 parts of the USERS command. The nickname list is not sent anymore
4999 by the server. Only Client ID and mode lists are sent in the USERS
5000 command. Changed this also to the protocol specification.
5002 The client now resolves the names and stuff after it receives
5003 the USERS list from the server when joining to the channel.
5005 * WHOIS and IDENTIFY commands has been changed to support multiple
5006 Client ID's per command. One can now search for multiple users
5007 in the network by sending only one WHOIS or IDENTIFY command.
5008 Changed the code and the protocol specifications.
5010 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5011 uses silc_server_command_whois_parse to parse the request. */
5013 * If normal server, do not parse the WHOIS and IDENTIFY requests
5014 before sending it to the router. Saves some time.
5016 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Fixed JOIN command on client library. Wrong number of arguments
5019 used to crash the client.
5021 * Added silc_server_channel_has_global function to check whether
5022 channel has global users or not.
5024 * Added silc_server_channel_has_local function to check whether channel
5025 has locally connected clients on the channel.
5027 * The silc_server_remove_from_one_channel now checks whether the
5028 channel has global users or not after given client was removed from
5029 the channel. It also checks whether the channel has local clients
5030 on the channel anymore. If it does not have then the channel entry
5031 is removed as it is not needed anymore.
5033 * The silc_server_notify now checks on JOIN notify whether the joining
5034 client is one of locally connected or global. If it is global then
5035 the channel has now global users on the channel and that is marked
5036 to the channel entry. Also, it now saves the global client to
5037 global list who is joining and JOINs it to the channel. This is
5038 for normal server, that is.
5040 Changed silc_server_send_notify_on_channel,
5041 silc_server_packet_relay_to_channel and
5042 silc_server_packet_send_to_channel check if we are normal server
5043 and client has router set (ie. global client) do not send the
5044 message to that client, as it is already routed to our router.
5046 * Implemented LEAVE notify type handling in silc_server_notify
5049 * Tested LEAVE command in router environment successfully. Tested
5050 with two routers, two servers and two clients.
5054 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5056 * Implemented SIGNOFF notify type handling in silc_server_notify
5059 * silc_server_remove_id now removes the client entry from all channels
5060 it has joined and thusly sends SIGNOFF notify type.
5062 * Rewrote the NAMES list generation in server by removing two excess
5063 loops. The lists are created now inside one loop.
5065 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * silc_server_remove_channel_user checks now also global list
5068 for channel and client.
5070 * silc_server_new_channel_user checks now both local and global
5071 list for channel and client. Fixed a bug in client id decoding.
5072 Used to decode wrong buffer.
5074 * silc_server_channel_message checks now both local and global
5075 list for channel entry.
5077 * Tested channel joining (hence JOIN) in router environment
5078 successfully. Tested with two routers, two servers and two
5081 * Tested channel message sending in router environment successfully.
5083 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Added silc_server_save_channel_key into server.[ch] to save the
5086 received channel key in Channel Key payload processing. It is
5087 also used in JOIN command reply handling.
5089 Equivalent function silc_client_save_channel_key added into
5090 client.[ch] into client library.
5092 * Changed JOIN command reply to send information whether the channel
5093 was created or not (is existing already) and the channel key
5094 payload. Changed protocol specs accordingly.
5096 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5097 the request was sent by ID and not by nickname. Crashed on
5100 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5103 now correctly save the received data.
5105 * silc_server_free_sock_user_data now notifies routers in the
5106 network about entities leaving the network.
5108 At the same time implemented functions silc_server_remove_id
5109 and silc_server_send_remove_id to receive and send REMOVE_ID
5110 packets. The packet is used to notify routers in the network
5111 about leaving entities. The ID removed will become invalid in
5114 * Added function silc_idlist_del_server into server. Removes and
5115 free's server entry from ID list.
5117 * silc_server_private_message function now checks, if we are router,
5118 that the destination ID really is valid ID, naturally.
5120 * In router when NEW_ID packet is received (for new client) the
5121 hash of the Client ID is saved in the ID Cache but the
5122 client->nickname is set to NULL, instead of putting the hash
5125 IDENTIFY command now also checks that client->nickname must be
5126 valid. If it is not if will request the data from the server who
5127 owns the client. Added new function
5128 silc_server_command_identify_check.
5130 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5131 to set the command to already allocated Command Payload.
5133 * Tested private message sending in router environment with two
5134 routers, two servers and two clients. Fixed minor bugs and now
5137 * Fixed segfault from client's NAMES command. Used to crash if
5140 * Forwarded packets must not be routed even if it is not destined
5141 to the receiver. Changed server code comply with this.
5143 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Added `require_reverse_mapping' boolean value to ServerParams
5146 structure. If TRUE (not default) the server will require that
5147 the connecting host has fully qualified domain name.
5149 If the reverse mapping is not required and hostname could not be
5150 found the IP address is used as hostname.
5152 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Implemented version string checking to both client and server.
5155 The check is incomplete currently due to the abnormal version
5156 strings used in development version of SILC.
5158 * Changed all command functions in server to use the new
5161 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Changed char *data to unsigned char *data in ID Cache system to
5164 support binary data as ID Cache data. Changed code to support
5165 binary data in lib/silccore/idcache.c.
5167 * Renamed silc_server_packet_relay_command_reply to
5168 silc_server_command_reply as it is normal packet receiving
5169 function. Rewrote the function to accept command replys for
5170 servers and not only for clients.
5172 * Mark remote router always as registered server if we are connecting
5173 to it. Otherwise, commands sent by the router to us are ignored.
5175 * All ID List find routines now returns the ID Cache Entry pointer
5176 as well if requested.
5178 * WHOIS command works now in router environment, tested with two
5179 routers, two servers and two clients.
5181 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5182 in router environment (as it is almost equivalent to WHOIS) but
5183 hasn't been tested thoroughly. Added new functions:
5185 silc_server_command_identify_parse
5186 silc_server_command_identify_send_reply
5187 silc_server_command_identify_from_client
5188 silc_server_command_identify_from_server
5190 * Disabled route cache adding because adding two different ID's with
5191 same IP replaces the old cache entry thus giving wrong route.
5192 The entry->router->connection is always the fastest route anyway
5193 so route cache may not be needed. Of course, new routes maybe
5194 established after receiving the ID when the entry->router->connection
5195 might not be anymore the most optimal.
5197 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Add route cache for received ID for fast routing.
5201 * Added silc_server_packet_route to route received packet on router
5202 that is not destined to us.
5204 * Renamed silc_server_get_route to silc_server_route_get.
5206 * Added id_string and id_string_len fields into SilcServer to
5207 include encoded ServerID for fast comparing without excess
5208 encoding of the ID's.
5210 * Cleaned up WHOIS command on server side. Added following static
5213 silc_server_command_whois_parse
5214 silc_server_command_whois_check
5215 silc_server_command_whois_send_reply
5216 silc_server_command_whois_from_client
5217 silc_server_command_whois_from_server
5219 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5220 arguments in command replies. All command functions should be
5221 updated to use this macro.
5223 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Minor typo fixes on command reply handling on server.
5227 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added silc_server_command_add_to_channel internal routine to add
5230 the client to the channel after router has created the channel and
5231 sent command reply to the server.
5233 * Added generic silc_server_send_command to send any command from
5236 * Use static buffer with ID rendering instead of duplicating data.
5238 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Fixed a channel user mode bug when joining to a channel server gave
5241 everybody channel founder rights, oops.
5243 * We mark ourselves as the router of the incoming server connection
5244 if we are router ourselves. This way we can check in some packet
5245 sending functions whether it is locally connected server. For
5246 incoming router connections we put NULL.
5248 * For router sending packets locally means now always sending the
5249 packet cell wide; to local clients and local servers. For normal
5250 server sending packet locally means sending it to only local
5253 * Fixed the JOIN command to really work in router environment. If the
5254 channel is created it is always created by the router. Router is
5255 also responsible of making the initial joining to the channel,
5256 sending JOIN notify to the sending server and distributing
5257 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5258 does not exist server doesn't do anything else but forward the
5259 command to the router which performs everything.
5261 * Added silc_server_send_channel_key function to send the Channel Key
5264 * Added silc_server_create_channel_key to create new channel key. The
5265 channel key is now re-generated everytime someone joins or leaves
5266 a channel, as protocol dictates. Note: channel->key_len is the
5269 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5272 packet_receive.[ch] to separate packet sending and receiving
5273 routines. The server.[ch] now includes everything else including
5274 actual packet processing (writing and reading data) and other
5277 Renamed silc_server_private_message_send_internal to
5278 silc_server_send_private_message. The routine is still though
5279 used only to relay private messages as server does not send
5280 private messages itself.
5282 Renamed silc_server_new_channel to silc_server_create_new_channel
5283 and added new function sicl_server_new_channel that handles the
5284 incoming New Channel packet. Added also new sending function
5285 silc_server_send_new_channel to send New Channel Payload.
5287 * Added new function silc_server_notify to process incoming notify
5288 packet to the server/router. Server may then relay the notify
5289 to clients if needed.
5291 * Added new function silc_server_new_channel_user to process incoming
5292 New Channel User packet. Router will redistribute the packet and
5293 send JOIN notify to its local clients and locally connected servers
5294 if needed. Normal server will send JOIN notify to its local client
5295 on same channel when received this packet. Added also corresponding
5296 sending function silc_server_send_new_channel_user to sent the
5299 * Added boolean route argument to send_notif_to_channel and
5300 packet_send_to_channel functions to attempt to route the packet
5301 if it is TRUE and send only locally if it is FALSE.
5303 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * silc_server_replace_id now broadcasts the received replace ID
5306 packet if it is not broadcast packet already. The router must
5307 broadcast to inform other routers about changed ID.
5309 * Added backpointer to server's router into SilcServer context in
5310 silcd/server_internal.h.
5312 * Fixed silc_server_packet_broadcast to send correct broadcast
5315 * The channel key is now distributed to the local client as soon
5316 as it is received from the router (in router environment) so that
5317 no other packet may be sent for the channel until client has
5320 * silc_server_remove_channel_user now broadcasts the received
5321 Remove Channel User packet if it is not broadcast packet already.
5322 The router must broadcast to inform other routers about removed
5325 * Added users field into SilcPacketContext that is a reference count
5326 of the context. One can increase the reference count by calling
5327 silc_packet_context_dup which is now changed to just increase the
5328 reference count instead of duplicating the data. The reference
5329 count is decresed by calling silc_packet_context_free that will
5330 free the data after the reference count hits zero.
5332 For now on the packet context and everything allocated into it
5333 (including the raw packet from network) must be freed by calling
5334 the new silc_packet_context_free function. Added also new function
5335 silc_packet_context_alloc that must be used now to allocate the
5336 context. This also means that if a routine is asynchronous from
5337 silc_[client/server]_packet_parse_type the packet context must
5338 be duplicated by calling silc_packet_context_dup. Otherwise it
5339 gets free'd after silc_[client/server]_packet_parse_type returns.
5340 Also, one must remember that if packet is duplicated then its
5341 reference count must be decresed by calling the free function as
5342 many times as it was duplicated.
5344 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5345 from both client and server.
5347 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Made joining to a channel working in router environment.
5351 * Cleaned up JOIN command on server side and create function
5352 silc_server_command_join_channel internal routine to make the
5355 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Changed silc_command_pending list to SilcDList. Also, added
5358 `ident' field to SilcServerCommandPending structure to identify
5359 the reply and to call correct callback.
5361 Added silc_server_command_pending_check function to replace the
5362 corresnponding macro. The silc_command_pending list is not
5365 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5366 to set identifier to previously allocated Command Payload. It
5367 is used to set identifier for command when resending Command
5370 * Added silc_command_payload_encode_payload to encode Command
5371 Payload buffer from SilcCommandPayload structure.
5373 * Added silc_argument_payload_encode_payload to encode Argument
5374 payload buffer from SilcArgumentPayload structure.
5376 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Changed WHOIS command to support router connection on server side.
5379 The whois request is always sent to router unless the server is
5380 standalone server. After server has received the reply from the
5381 router will it send the reply to the client.
5383 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5384 broadcast received broadcast packet. The function is used only
5385 by router. The broadcast packet is always sent to the router's
5388 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5389 render given ID to printable string, for log files for example.
5391 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Made basic router to router connections working. At least they
5394 can now connect to each other but nothing really works the way
5395 they are supposed - yet.
5397 * Added new initiator token to RouterConnection configuration
5398 file in silcd/serverconfig.[ch]. It is used to tell whether we
5399 are the initiator to the remote router or whether we'll expect
5400 the other end to connect.
5402 * Moved registering of listener task to silc_server_init, hence
5403 the server starts listenning as soon as it is run, even if it
5404 does not have connections to other routers. Let's see how well
5407 * Changed default connection retry timeouts for more suitable in
5410 * Removed cipher and such arguments from silc_idlist_add_client
5411 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5412 Added new function silc_idlist_add_data to add the keys and stuff
5415 * Added SilcIDListData structure and added it to SilcClientEntry
5416 and SilcServerEntry as their first field in the structure. This
5417 way we can explicitly cast the ID entries to the SilcIDListData
5418 structure and get common data for the entries. In past, we had
5419 to first check what type of connection it is and then cast it to
5420 correct ID entry type. Now, we can directly cast the opaque
5421 pointer to the SilcIDListData (no matter what ID entry it actually
5422 is) and get the data needed.
5424 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5427 in some circumstances even if threre were timeout tasks, though not
5428 IO tasks, but tasks anyway. Now fixed.
5430 * Defined SilcServerConnection structure to hold connection specific
5431 stuff about directly connected servers and routers. The definition
5432 is currently in silcd/server_internal.h. I thought about having
5433 a bit more important role fro this struct but for now it is used
5434 only when connecting to other server (or router actually).
5436 * Added connecting retry support in server when connecting to
5437 router(s). The retry feature implement exponential backoff
5438 algorithm. Also, added SilcServerParams structure to hold default
5439 parameters for server. For now, it include these retry settings
5440 and are hard coded. After server is moded to be as Silc Server
5441 Library this structure will be more important.
5443 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Changed client librarys channel->clients table to SilcList and
5446 changed code accordingly.
5448 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Changed client's channel table to SilcList and changed code
5451 accordingly. Also changed SilcChannelClientEntry to include back-
5452 pointer to the channel so that client entry can use that structure
5453 as list as well and we have fast cross-reference to the channel.
5454 This change dramatically decreased the complexity of channel
5455 handling with client entry and vice versa (removed one extra
5456 loop when searching for channel entry from many functions).
5458 * Changed server->sim from table to SilcDList and changed code
5461 * NAMES command can now be used from user interface. It will show
5462 the user list on the channel, neatly.
5464 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5465 Code now saves realname of the user if it becomes available.
5467 * Renamed configure.in to configure.in.pre and made ./prepare
5468 script to automatically add correct version string to
5469 configure.in which it creates from configure.in.pre.
5471 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * NAMES command reply now shows users mode with the nickname when
5476 * Moved silc_client_ch[u]mode[_char] functions from
5477 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5478 place sucks, they are utility functions and should be in some
5481 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5483 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5486 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Added TRQ (efficient deque and list library) into lib/trq. This is
5491 a very good list library that is currently used in the SILC. Defined
5492 SilcList API over the library because I didn't like the API very
5493 much. See lib/trq/silclist.h for the API and examples of how to
5494 use the API. Fixed various places in the code to use the new
5495 SilcList API. The SilcList is meant for lists that has a structure
5496 already defined as a list. It is not suitable to add just some
5497 context to the list (in TRQ, the context is the list actually).
5499 So, I defined SilcDList that can be used for the purpose where
5500 predefined list structure does not exit. This can be used as
5501 such list. Now some context just can be added to the SilcDList.
5502 Currently this list is not used in the SILC just yet, though there
5503 are a lot places where this can replace dynamically allocated
5504 tables and I will fix these places, later, to use SilcDList.
5505 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5506 and use TRQ internally).
5508 Also fixed some annoying warning messages that the original TRQ
5509 code generated. Also minor changes to TRQ's Makefile.in.
5511 * Added support for querying by Client ID to both WHOIS and
5512 IDENTIFY commands into server, as required by the protocol.
5514 * Removed method function pointers from SilcBuffer structure. They
5515 weren't used to anything and just increased the context size for
5516 no good reason. This change also made silc_buffer_alloc and
5517 silc_buffer_free functions inline functions.
5519 * Disabled command flooding detection support until it's fixed so
5520 that it accepts commands in but does not execute them more than once
5523 * Added silc_net_localhost(), to return local hostname, into
5524 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5525 that must be initialized before calling silc_client_init.
5527 * Added new function: silc_server_send_notify_on_channels to send
5528 notify messages to all channels client has joined. It is assured
5529 that the message is sent only once per client.
5531 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5532 lib/silcutil/silcutil.[ch] as silc_format function. The new
5533 function is generic and is used by server as well, not only by
5534 the logging routines.
5536 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5537 the provided version string was not acceptable. Added new function:
5538 silc_ske_check_version into lib/silcske/silcske.h. The function
5539 must be implemented by the application (client or server) and it
5540 does not reside in the SKE library. The function checks the version
5541 string remote end sent.
5543 * Added back pointers (to opaque context and to SilcSocketConnection)
5544 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5546 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5547 duplicate packet context structure.
5549 * Changed `notify' client operation to send same arguments as client
5550 receives from server except for ID's. ID's are mapped to correct
5551 ID entry and that is returned. Also, if channel entry is not sent
5552 by server but the notify is for channel the channel entry is sent
5553 to application (otherwise application doesn't know that it is for
5554 channel (library gets it from packet's Destination ID)).
5556 * Added silc_client_remove_from_channels into client library to
5557 remove a client from all channels it has joined to. Used when
5558 received SIGNOFF notify from server. Added also new function
5559 silc_client_replace_from_channels to replace old ID entry with
5560 new ID entry on all channels. Used when received NICK_CHANGE
5563 * Fixed ID Cache list handling in silc_idlist_get_client in
5564 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5565 to get (or query) client by ID.
5567 * Updated TODO list.
5569 * Added connection authentication status message defined by the
5570 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5571 support for these into the code in client and server side.
5573 * Added generic function silc_client_send_command to send any command
5574 with variable argument list. Application should use this function
5575 to send commands if the command functions provided by the library
5576 does not suite for the application's user interface needs.
5578 * Added new `failure' client operation. Application is notified about
5579 received failure packet if client is executing a protocol. In this
5580 case the protocol's execution has failed.
5582 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5583 is required by the protocol.
5585 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5586 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5589 * Added status flag to SilcSKE object to indicate realtime status
5590 of the SKE protocol.
5592 * Application receives now exactly same command reply arguments as
5593 the library receives from server. However, if ID is received the
5594 corresponding ID entry is returned to the application (eg. Client
5595 ID is mapped to correct SilcClientEntry entry and that is returned).
5596 Changed command_reply client operation due to this change.
5598 * Changed all ID's in commands and in command replys as ID Payloads.
5599 Change affected both client and server side codes.
5601 All ID's sent in SILC network (with execption of ID's in SILC
5602 Packet header) are sent in ID Payload to support variable length
5605 * Server now notifies nick changes and notifies all clients on
5606 the channels about the new nickname (about the new Client ID,
5609 * Implemented CMODE command to change channel modes. Supports all
5610 channel modes defined by the protocol specs except ban and invite
5611 lists. (Also, private channel key mode is supported but support for
5612 setting private channel key in client is missing, thus, this mode
5613 has no effect on client side (except that server requires that the
5614 client uses private channel key and normal channel traffic does not
5617 Also, invite mode works per se, but INVITE command does not work
5618 yet correctly, so you can set channel as invite only channel but
5619 inviting clients to the channel does not work (it is yet to be
5620 thought what's the best way to do it).
5622 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5623 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5624 Implemented CUMODE command to change user's mode on the channel.
5625 Supports all modes defined by the protocol specs.
5627 * Added NAMES command reply to return users modes on the channel.
5629 * Removed unnecessary and slow ciphers from lib/silccrypt.
5631 * Set SO_KEEPALIVE option to connection sockets by default.
5633 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5635 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5636 redefined the Notify Payload into protocol specs.
5638 * Added silc_id_payload_parse_id to get ID directly from raw
5641 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5644 accept searching by Client ID as well.
5646 * Added support for LEAVE and SIGNOFF notify types in client library.
5648 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5649 to parse ID Payload from raw data.
5651 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Added flags parameter into silc_ske_assemble_security_properties
5654 function in lib/silcske/silcske.[ch].
5656 * Changed notify client operation to fit better for notify messages
5657 sent by server. The notify payload received from server is now
5658 passed to the application (after parsing it to SilcNotifyPayload).
5659 It is application's responsibility to retrieve the arguments
5660 from the payload and show the message the way it wants. The message
5661 sent by server is implementation specific.
5663 * Changed public keys to comply with the protocol specification.
5664 Old public keys are not supported anymore and are not compatible.
5666 * Removed nickname from Channel Payload as the latest draft removed
5667 it. The client must resolve the nickname from the NAMES command
5668 reply received when it joined the channel.
5670 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5672 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Fixed some errors in protocol specification drafts.
5676 * Created lib/silccore/silcnotify.c to implement Notify Payload
5677 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5678 generic payloads described by protocol specifications. The file
5679 includes implementations for ID Payload and Argument Payload.
5681 * Changed Command Payload implementation to use the new Argument
5682 Payload. Changed command_xxxx_payload to command_payload_xxxx
5683 to comply with SILC coding conventions.
5685 * Added suppport for Argument Payload handling in Notify Payload
5686 implementation as protocol requires it. Added the new support
5687 into server and client lib as well.
5689 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Added support for multiple nicknames on same channel. [n] is
5692 added locally to the nickname if there are more than one same
5693 nicknames on the channel.
5695 * Server now sends all nicknames that matched WHOIS request.
5696 Client also shows the list received from server.
5698 * Added TOPIC command to client side. User can now set and show
5699 current topic on channel.
5701 * Added MOTD command to client and server. Also, server sends the
5702 motd when client connects to the server.
5704 * Changed version strings to comply ISO 8601.
5706 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Fixed protocol error handling in client library. It should now
5709 cope even if the SKE fails for some reason.
5711 * Made new protocol specification drafts for submitting to IETF.
5713 * Implemented TOPIC command to server in silcd/command.c.
5715 * Added two new notify types into lib/silccore/silcnotify.h:
5716 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5717 notify nickname change and topic setting/change on a channel.
5719 * API change of command_reply operation in client library. The
5720 application gets now the status type received from server as well.
5722 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5726 * Cras fixed and optimized the packet handling even further and
5727 it should work now. Minor change to the prototype of function
5728 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5730 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Added new function into lib/silcutil/silcschedule.[ch]:
5733 silc_schedule_with_fd to select() a specified fd. The function
5734 returns after timeout expires or data arrives or goes. The
5735 function is used by packet routines to wait that all data is
5736 received from network.
5738 * Fixed data reading from network in lib/silccore/silcpacket.c.
5739 The code now assures that all data is read from the fd and then
5740 continues packet processing. This was a bug fix since the code
5741 used to drop some data in some circumstances.
5743 * Added new function into lib/silcclient/client.[ch]:
5744 silc_client_start_key_exchange to start key exchange after
5745 connection has been established to server. The code internally
5746 now uses this funtion but its main purpose was to provide it
5747 for applications that perform their own connecting. After
5748 application has created a connection it merely calls this
5749 function to start the key exchange between client and server.
5750 The library takes care of everything else after that.
5752 Updated also lib/silcclient/README to explain the usage of
5755 * Do not send to application information that connection has
5756 been established. Application gets notified it by connect
5759 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Applied cras's patch to add silc_schedule_one function. The
5762 function runs scheduler once and returns.
5764 * Fixed the scheduler after cras messed it up. The timeout
5765 handling works now as it's supposed to work.
5767 * Added into lib/silccore/ silcnotify.h to include notify
5768 message types support. Changed silc_server_send_notify*
5769 functions, in server.[ch], to support those new notify types.
5770 Added the support for the notify types into client library,
5771 as well. Added new notify client operation into ops.h in
5774 * Changed silc_server_packet_send_to_channel to send normal
5775 packets instead of just channel message packets. The function
5776 is now used to send the notify packets to channels. It is not
5777 used to send channel message packets anymore, as server never
5780 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5781 va_arg()s as it seems to require it nowadays. I guess, if SILC
5782 is compiled with older va_arg() the new code should work anyway.
5784 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Splitted core library. Core library (lib/silccore) includes
5787 now only SILC protocol specific core (and common) components.
5788 Created new utility library (lib/silcutil) that includes more
5789 generic purpose stuff. The stuff for util library was taken
5790 from the old core library. This was minor and easy split.
5792 * Created SILC Client Library (lib/silcclient) that includes
5793 implementation of the SILC client without user interface. This
5794 was major move from silc/ directory. The code has been changed
5795 so that it is transparent towards the user interface. The
5796 silc/ directory includes now the same user interface as before
5797 and it uses the new client library. Read lib/silcclient/README.
5798 Basicly, the client library performs everything else related
5799 to SILC except user interface handling. Also, configuration
5800 files are considered to be part of user interface and library
5801 does not handle them.
5803 This change also changed a lot of structures, function naming etc.
5804 Most important change was that SilcClientWindow object was
5805 renamed to SilcClientConnection in the client library. Created
5806 also new file lib/silcclient/ops.h. Also added new files
5807 silc/local_command.[ch] and silc/client_ops.[ch].
5809 All these changes were made to make it easier for user interface
5810 designers to create what ever user interface for the SILC client
5813 It is also expected that the server will be moved to lib
5814 directory as well and SILC Server Library will be created;
5815 sometimes in the future.
5817 * Removed Local commands from lib/silccore/silccommand.h as
5818 they are application specific and new client library does not
5819 handle any of those anymore.
5821 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5822 old client implementation in silc/.
5824 * Added support for callback functions in SILC_LOG_* macros.
5825 Application can now set its own callbacks that will be called
5826 instead of using the default functions that will always print
5827 the debug messages to stderr (or stdout). Also, debugging can
5828 now be disabled by setting silc_debug to FALSE and re-enabled by
5829 setting it to TRUE. Note, that logging will still work even
5830 if debugging is disabled.
5832 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5833 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5834 silc_log_reset_debug_callbacks.
5836 * To enable debugging in silc client one must give now -d
5837 option on command line.
5839 * Changed silc_schedule_init to automatically allocate task queues
5840 if they are not allocated before calling it.
5842 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Added GMP 3.1 into math library.
5846 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5849 a channel in SILC network. The packet is used by servers and
5850 routers to notify other routers that user has left a channel.
5851 This little feature was missing until now. Added the feature
5852 to protocol specification as well.
5854 Added functions: silc_server_send_remove_channel_user and
5855 silc_server_remove_channel_user into server.[ch].
5857 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5858 lib/silccore/silcpacket.h. However, they are not implemented
5861 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Fixed joining to a channel and sending channel messages
5864 between server and router. The channel message sending should
5865 now work inside a cell.
5867 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * Fixed the private message sending between server and router.
5870 The private message sending should now work inside a cell.
5872 * Added silc_server_replace_id into server.[ch] to replace
5873 existing ID in the SILC network.
5875 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5876 and silc_idlist_replace_server_id into idlist.[ch] in server.
5878 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Fixed the server to server connections. Server can again now
5881 connect to router. Router to router connections probably does
5884 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added dynamic protocol registering support. Now protocols can
5887 registered and unregistered on the fly. Patch by cras.
5889 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added lib/contrib directory to hold routines that some platforms
5892 don't have but are needed by SILC.
5894 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5895 into lin/contrib to provide getopt() and getopt_long() for
5896 those who don't have it.
5898 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Added AWAY command to client. When away message is set and
5901 client receives a private message packet the client automatically
5902 replies to the sender with the away message.
5904 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5905 bug seemed to be the cause of recent problems when compiling
5908 * Added version detection support to SKE protocol specification
5909 and added the new changes to the SKE implementation as well.
5910 There were other minor changes in the SKE protocol as well.
5912 Many changes in lib/silcske/silcske.[ch] and in
5913 lib/silcske/payload.[ch].
5915 * Added ^U functionality, clear input line. Patch from cras.
5917 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Mainly small bugfixes on core library. Fixed some debugging
5920 logging and buffer overflow in silclog.c.
5922 * Updated config.sub and config.guess on the distribution tree.
5924 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added command lagging support in server. Client may execute
5927 commands now only once in two seconds.
5929 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Optimized packet reception. MAC computation and checking is now
5932 also more optimized. A lot previously duplicated code is now
5933 used as generic by both client and server.
5935 * Fixed key pair generation in clientutil.c
5937 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added into lib/silccore/silcbufutil.[ch] new function;
5940 silc_buffer_realloc.
5942 * Moved generic packet sending/encryption functions to
5943 lib/silccore/silcpacket.[ch] from client and server. Some
5944 rewriting of the functions.
5946 * Moved all generic packet reception/decryption functions to
5947 lib/silccore/silcpacket.[ch] from client and server. The
5948 packet processing is now much cleaner in both client and server.
5949 These were major changes in both client and server.
5951 * Created many common functions in server to do packet sending.
5952 Previously code were duplicated a lot, this has been removed
5955 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Rewrote major parts of the ID cache system. Don't know
5958 whether it is better now or not but at least the API is more
5961 * Major rewrite on ID cache stuff on client because of the ID
5962 cache API changes. Added idlist.c to client.
5964 * Also major rewrite on ID cache stuff on server as well.
5965 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5966 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5967 in hand, instead they are all put into the ID cache system now.
5968 All server_idlist_* routines uses ID cache now instead of
5969 traversing its own lists (those lists does not exist anymore).
5970 SilcIDList though still exists. Also, SilcXXXEntry's are
5973 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Finally made the SKE implementation compliant to the protocol
5976 specification. All mp integers are now binary encoded as
5977 opposed being HEX encoded.
5979 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5982 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5983 functions: silc_[encode/decode]_pem. Also added function
5984 silc_encode_pem_file to PEM encode with newlines ('\n') for
5987 * SILC public keys are now encoded either PEM or binary. Same
5988 option is for private keys as well. By default private keys
5989 are binary encoded and public keys PEM encoded. Silly HEX
5990 encoding were removed.
5992 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5993 function to create fingerprints.
5995 * Fixed a bug in SHA1; does not change the original data anymore.
5997 * Partly implemented INFO command on client and server side.
5998 Fixed CLEAR command. Changes to SERVER command; show current
5999 server(s) when giving command without arguments. Added
6000 VERSION command to client.
6002 * Added check to server that unregistered connections cannot
6003 execute commands (unless it is specificly allowed).
6005 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Fixed screen refresh.
6009 * Fixed channel joining bug from client. On some circumstances
6010 client tried to join to a channel it had already joined.
6012 * Added public key verification process into client's protocol.c.
6013 The client now verifies the public key from user and saves
6014 it into ~./silc/serverkeys/ directory.
6016 Added into: clientutil.[ch]: silc_client_verify_server_key.
6018 * Changed SKE protocol's silc_ske_initiator_finish function
6019 to accept callback function that verifies the received public
6020 key. Removed old silc_ske_verify_public_key function.
6022 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6025 silc_pkcs_private_key[_data]_set.
6027 * Made the password and public authentication more cleaner in
6028 server's protocol.c.
6030 * Removed historic and obsolete protocol `channel_auth' from
6031 both client and server.
6033 * Removed wrong way of sending command status messages from
6034 server to client in server's command.c. The old way violated
6035 protocol specification.
6037 Changes to silccore/silccommand.[ch]: removed
6038 silc_command_encode_status_payload -> not needed anymore,
6039 changed silc_command_encode_payload_va to accept extra
6040 argument on variable argument list. The argument type must
6041 now be provided to the function. Also, added new function:
6042 silc_command_encode_reply_payload_va which is same as
6043 normal command_encode_payload_va except command status type
6044 is provided as extra argument.
6046 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Added ~./silc directory handling. The directory includes the
6049 public and private keys for the client.
6051 Added silc_client_check_silc_dir, silc_client_create_identifier
6052 and silc_client_load_keys.
6054 * Implemented SILC protocol compliant public key. Added public
6055 and private key saving to and loading from files.
6057 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6058 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6059 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6060 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6061 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6063 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6064 silc_pkcs_load_[public/private]_key.
6066 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Added silc_server_get_route (route.[ch]) to get connection
6069 data for the fastest route for given ID.
6071 * Implemented INVITE command on client and server. The command
6072 were re-defined in the SILC Protocol Specification and the
6073 implementation now complies with the specification.
6075 * Implemented PING command on client and server.
6077 * Implemented NAMES command on client and server. The server side
6078 supports currently only normal server not router server yet.
6079 Some changes to NAMES definition in SILC protocol specification.
6081 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Implemented LEAVE command on client and server.
6085 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6086 again. This change was made to the protocol as well. Server
6087 should not violate the protocol specification anymore.
6089 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6092 was tested. SOCKS4 was not but should work anyway.
