10 * Fixed MOTD to return the MOTD file server name. Affected
13 * Added INFO command reply handling to the Irssi SILC Client.
14 Affected file irssi/src/silc/core/client_ops.c.
16 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
18 * Fixed the silc_idcache_list_* routines to really support
19 the dynamic list. Fixes a crash. Affected file is
20 lib/silccore/silcidcache.c.
22 * Fixed the LIST command reply to really call LIST command's
23 pending callbacks. Affected file silcd/command_reply.c.
25 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
27 * Update conn->local_entry->nickname after giving NICK
28 command. Affected file lib/silcclient/command.c.

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

308 in JOIN command. Affected file lib/silcclient/command.c.
310 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Assure that silc_server_close_connection cannot be called
313 twice for same socket context. Affected file is
316 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Send error message to application if opening file for
319 writing during file transfer fails. Affected file is
320 lib/silcclient/client_ftp.c.
322 Remove all file transfer sessions for a client that we're
323 removing from ID cache.
325 Affected file is lib/silcclient/client_ftp.c.
327 * Fixed silc_net_addr2bin to return correct address. Affected
328 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
330 * Fixed file transfer session removing on signoff notify.
331 Affected file irssi/src/silc/core/silc-servers.c.

334 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
335 Affected file lib/silcclient/silcapi.h.
337 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
339 * Fixed a crash in silc_client_ftp_free_sessions and
340 silc_client_ftp_session_free_client. Affected file
341 lib/silcclient/client_ftp.c.

344 to indicate if the server entry is disabled. Affected file
345 silcd/idlist.h, silcd/command[_reply].c.
347 * SILC server adds now /var/run/silcd.pid everytime it is
348 started. Affected file silcd/silcd.c.
350 * Added silc_server_packet_send_clients to send a packet to
351 the provided table of client entries. Affected file
352 silcd/packet_send.[ch].

355 client library. Affected file lib/silcclient/client_prvmsg.c.
357 * Do not actually remove the client directly from ID cache
358 during SERVER_SIGNOFF, but invalidate it. This way we
359 preserve the WHOWAS info for the client. Affected file
362 * Fixed SERVER_SIGNOFF notify handling in the server. The
363 server is now able to process incoming SERVER_SIGNOFF notify
364 for a server that it doesn't even know about. It will remove
365 the clients provided in the notify. Affected file
366 silcd/packet_receive.c.
368 * Check for partial packet in data queue after every packet that
369 was found from the queue. Return and wait for more data if
370 there is partial data in queue. Affected file is
371 lib/silccore/silcpacket.c.
373 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

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

447 * Added silc_net_localip to return local host's IP address.
448 Affected file lib/silcutil/silcnet.[ch].
450 * If key exchange or rekey protocol is active for a connection
451 parse all packets syncronously since there might be packets
452 in packet queue that we are not able to process without first
453 processing packets before them. Affected file silcd/server,
454 lib/silcclient/client.c.
456 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
457 whether library should continue processing the packet.
458 Affected file lib/silccore/silcpacket.h.
460 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
461 SilcSFTPMonitorData to SFTP server to monitor various

489 lib/silcutil/silcutil.[ch].
491 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Resolve the client info when received private message or
494 channel message for a client which nickname we don't know.
495 Affected files lib/silcclient/client_prvmsg.c and

498 * Do not crash in /KEY if client is not connected. Affected
499 file irssi/src/silc/core/silc-channels.c.
501 * Added SilcClientStatus field to the SilcClientEntry in the
502 lib/silcclient/idlist.h.
504 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
505 is incomplete and is being resolved, it won't be resolved
508 Make sure also that USERS command reply does not resolve
509 twice information. Affected file is
510 lib/silcclient/command_reply.c.
512 Make sure that silc_client_get_clients_by_list does not
513 resolve twice same information.
515 * Check for valid client->id in the silc_server_free_client_data.
516 Affected file silcd/server.c.
518 * Fixed /GETKEY nick@server not to crash if the server entry

526 * Better checks for non-printable chars in nick added.
527 Affected file silcd/command.c.
529 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
531 * Call the silc_server_udpate_servers_by_server in the
532 primary router that comes back online in the backup resuming
533 protocol. Otherwise it routes packets wrong. Affected file
534 silcd/server_util.[ch], silcd/server_backup.c.
536 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
538 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
539 lib/silcutil/silcbuffmt.[ch].
541 * Redefined the SILC packet header to include the padding
542 length. Affected file lib/silccore/silcpacket.[ch].
544 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
545 length for maximum padding up to 128 bytes). Affected
546 file lib/silccore/silcpacket.h.
548 * Removed all backwards support for old 0.5.x MAC thingies.
549 The SILC packet header change makes it impossible to be
550 backwards compatible.
552 * Send the ENDING packet with timeout in the backup resuming
553 protocol. This is to assure that all routers has connected
554 to the primary router. Affected file silcd/server_backup.c.
556 * Changed the RNG to take the first IV from random data. It
557 used to take it from zero actually. Changed the RNG also
558 to use /dev/urandom during session. /dev/random is used
559 in initialization. Affected file lib/silccrypt/silcrng.[ch].
561 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
563 * Changed the SILC packet header to have the first two bytes
564 (the packet length) encrypted. Affected files aroung the
565 code tree, lib/silccore/silcpacket.[ch]. Removed the
566 SilcPacketCheckDecrypt callback. It is not needed anymore
567 since the silc_packet_receive_process will determine now
568 whether the packet is normal or special.
570 * Implemented the unidirectional MAC keys. Affected files
571 lib/silcske/silcske.c, silcd/protocol.c and
572 lib/silcclient/protocol.c.
574 * Implemented the packet sequence number to the MAC computation.
575 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
576 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
577 lib/silcclient/protocol.c.
579 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Allow backup router to announce servers. All servers
582 announced by backup router are added to the global list
583 automatically. Update hte server's socket to our primary
584 router also when backup router announces a server.
585 Affected file silcd/packet_receive.c.
587 * Do not update the client->router in the function
588 silc_server_udpate_clients_by_server if the client is on
589 global list. We might fail to find any specific server
590 for locally connected clients and local cell clients. They
591 should still use the `from' and not `to' as client->router.
592 This fixes backup router resuming protocol. Affected file
595 * Decrease channel statistics count only if the channel
596 deletion worked. Affected files are silcd/server.c and
599 * Added silc_server_update_servers_by_server to update origin
600 of all server entries. Used during backup router protocol.
601 Affected files silcd/server_util.[ch], silcd/server.c. and
602 silcd/backup_router.c.
604 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
605 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
606 silc_hmac_get_hash and silc_hmac_get_name. Affected file
607 lib/silccrypt/silchmac.c.
609 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
611 * Assure that router cannot reroute the same channel message
612 to the sender. Affected file silcd/packet_receive.c.
614 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Made better checks that the channel message is not sent
617 to the router it came from. Affected file is
618 silcd/packet_send.c. Fixed memory leak too.
620 * Announce informations for incoming router connection, but
621 only after checking if it is replaced by backup router.
622 Affected file silcd/packet_receive.c.
624 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Fixed the backup resuming protocol to work in multiple
627 router environment. Affected file silcd/server_backup.c.
629 * Route packet only to one router in the function
630 silc_server_packet_send_to_channel. Affected file is
633 * Fixed silc_server_send_notify_dest to set the broadcast
634 flag. Fixed the silc_server_send_notify_topic to actually
635 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
636 Affected file silcd/packet_send.c.
638 * Changed the SFTP Filesystem interface. Changed the
639 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
640 the filesystem operation function. The SilcSFTPFilesystem
641 is now a context that is allocated by all filesystem allocation
642 functions and it already includes the operations structure
643 and filesystem specific context. It is given as argument
644 now to the silc_sftp_server_start. This made the interface
645 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
646 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
648 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Changed the backup router adding and getting interfaces
651 in the server. The router that will be replaced by the
652 specified backup router is now sent as argument. Affected
653 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
656 * Added silc_net_addr2bin_ne to return the binary form of
657 the IP address in network byte order. Affected files
658 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
660 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Check for existing server ID in silc_server_new_server
663 and in silc_server_connect_to_router_final and remove the
664 old entry if it exists. Affected file silcd/packet_receive.c,
667 * Send the channel message always to only one router, either
668 in upstream or downstream. Affected file is
671 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
673 * Wrote the definition of the backup resuming protocol to the
674 protocol specification.
676 * Removed one redundant channel key generation from normal
677 server during joining procedure. Removed one redundant
678 channel key sending from server to router during joining
679 procedure. Affected file silcd/command.c.
681 * Made minor bugfixes to the backup router resuming protocol.
682 Affected file silcd/server_backup.c, server.c.
684 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Added --disable-asm configuration option. Affected files
687 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
690 * Implemented the backup resuming protocol that is used to
691 resume the primary router position in the cell after the
692 primary router comes back online. Affected files
693 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
694 and silcd/server_util.[ch].
696 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Sleep two (2) seconds after sending QUIT command to server.
699 Affected file lib/silcclient/command.c.
701 * Assure that if outgoing data buffer is pending do not force
702 send any data. Affected file silcd/packet_send.c.
704 * Assure that if outgoing data buffer is pending do not force
705 send any data. Affected file lib/silcclient/client.c.
707 * Implemented the backup router support when the primary router
708 goes down. The servers and routers can now use the backup
709 router as new primary router without loosing connectivity.
711 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
713 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
714 in the server to indicate disabled entry. All data read
715 from the connection will be ignored and no data is sent
716 for entry that is disabled. Affected files are
717 silcd/idlist.h, silcd/server.c.
719 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
721 * Created SFTP client and server test programs in the
722 lib/silcsftp/tests directory.
724 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Implemented memory filesystem (virtual filesystem) for
727 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
730 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Implemented the SFTP (SSH File Transfer Protocol) to the
733 lib/silcsftp. It includes SFTP client and SFTP server
736 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
738 * Moved lib/silccore/silcprotocol.[ch] to the
739 lib/silcutil library.
741 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
742 take variable argument list pointer as argument. Affected
743 file lib/silcutil/silcbuffmt.[ch].
745 * Added silc_buffer_set function that is used to set data
746 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
747 Affected file lib/silcutil/silcbuffer.h.
749 * Changed various routines in the core library to use the new
750 silc_buffer_set instead of allocating new buffer only for
753 * Added 64-bit value formatting and unformatting support to the
754 silc_buffer_[un]format routines. Affected file is
755 lib/silcutil/silcbuffmt.[ch].
757 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
758 to includes/bitmove.h.
760 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
762 * Fixed channel user mode saving in client library. Affected
763 file lib/silcclient/command[_reply].c.
765 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
767 * Defined the file transfer to the SILC Protocol. Added
768 new packet type SILC_PACKET_FTP and defined File Transfer
769 Payload. The mandatory file transfer protocol is SFTP
770 (SSH File Transfer Protocol). Affected file in addition
771 of the internet draft is lib/silccore/silcpacket.h.
773 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
774 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
775 is used as part of backup router protocol when the primary
776 router of the cell is back online and wishes to resume
777 the position as primary router.
779 * Redefined the MAC generation keys in the protocol. The
780 same key is not used anymore in both direction. Both
781 direction will now use different keys for sending and
782 receiving. This fixes a potential security flaw. This
783 change causes incompatibilities in the protocol.
785 * Redefined also the MAC computation from the packet.
786 An packet sequence number is now added to the MAC
787 computation. This prevents possible replay attacks against
788 the protocol. This change too causes incompatibilities
791 Added `sequence' field to the SilcPacketContext to hold
792 the current sequence number for the packet.
794 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Added `created' field to the SilcIDListData in the file
797 silcd/idlist.h to indicate the time when the entry was
800 * Added `created' field to the SilcChannelEntry too. Affected
803 * Added `creation_time' aguments to all the announcement functions
804 in the server. If it is provided then only the entries that
805 was created after the provided time frame are actually
806 announced. Affected file silcd/server.[ch].
808 * The protocol says that the Channel ID's IP address must be
809 based on the router's IP address. Added check for this in
810 the silc_server_new_channel when processing incoming New Channel
811 Payload. Affected file silcd/packet_receive.c.
813 * Print out the correct version with --version in SILC client.
814 Affected file irssi/src/silc/core/silc-core.c.
816 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Fixed WHOWAS command to check for completnes of the client
819 entry always, not just when the command is coming from client.
820 Affected file silcd/command.c.
822 * Added new function silc_server_packet_queue_purge to purge the
823 outgoing data queue to the network. After the function returns
824 it is guaranteed that the outgoing packet queue is empty.
825 Affected file silcd/packet_send.[ch].
827 * Purge the outgoing packet queue in the rekey protocol's final
828 callback to assure that all rekey packets go to the network
829 before quitting the protocol. Affected file silcd/server.c.
831 * Added silc_client_packet_queue_parse as similar function as
832 in server to the client library. The affected file is
833 lib/silcclient/client.c.
835 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Splitted silcd/server.c and created silcd/server_util.[ch]
838 for utility functions.
840 * Added new socket flag SILC_SF_DISABLED to indicate that the
841 connection is open but nothing can be sent to or received from
842 the connection. Affected file lib/silcutil/silsockconn.[ch].
843 The checking for disabled socket is checked in the low level
844 silc_socket_write and silc_socket_read functions.
846 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Allow only nicknames and channel names that fits into the
849 7-bit unsigned char ASCII set. Affected file silcd/command.c.
851 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
853 * When processing JOIN command reply in server check that if
854 the channel exists in our global list we'll move it the local
855 list. Affected file silcd/command_reply.c.
857 * Fixed the check whether client is joined on the channel already
858 in JOIN command. Affected file lib/silcclient/command.c.
860 * Fixed the JOIN command reply to check whether the channel
861 already exists. Affected file lib/silcclient/command_reply.c.
863 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Added silc_ske_status_string to map the SKE error numbers
866 to readable strings. The affected files are
867 lib/silcske/silcske[_status].[ch].
869 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Do not show the private channels on the WHOIS channel list
872 as it is not allowed by the protocol. The affected file is
875 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
877 * Assure that the packet length digged from the actual packet
878 is something sensible in the silc_packet_decrypt_rest_special
879 in lib/silccrypt/silcpacket.c.
881 * Free and NULL the allocated pointer in silc_hmac_alloc if
882 the HMAC allocation fails. The affected file is
883 lib/silccrypt/silchmac.c.
885 * Print the selected security properties to the log files in
886 the server. Affected file silcd/protocol.c.
888 * Add SKE's reference counter even if calling the completion
889 callback manually. Otherwise it goes negative, although it
890 does not cause any problems. The affected file is
891 lib/silcske/silcske.c.
893 * Remove the client entry with short timeout after giving the
894 KILL command. Affected file lib/silcclient/command.c.
896 * Fixed to send error reply in WHOIS and IDENTIFY commands in
897 case all found clients are already disconnected (WHOWAS would
898 found them) in the server. Affected file silcd/command.c.
900 * Update the last_receive (time of last data received) to be
901 updated only when received private or channel message so that
902 the idle time showed in WHOIS makes more sense.
904 * Added boolean field `valid' in to the SilcClientEntry in the
905 client library to indicate whether the entry is valid or not.
906 This fixes the nickname change bug on channel when changing
907 the nickname to be same than the old (like nick to Nick) the
908 nickname formatter doesn't set the new nick anymore to Nick@host.
909 Affected file lib/silcclient/idlist.[ch].
911 * Now actually fixed the nickname changing on disconnection.
912 Added new function silc_change_nick to the Irssi SILC Client.
913 Affected file irssi/src/silc/core/client_ops.c,
914 irssi/src/silc/core/silc-nicklist.[ch].
916 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Check that the public key exists in the GETKEY command before
919 trying to encode it. Affected file silcd/command.c.
921 * Print some notifications on received public keys with GETKEY
922 command in the Irssi SILC Client. Affected files are
923 irssi/src/fe-common/silc/module-formats.[ch],
924 irssi/src/silc/core/client_ops.c.
926 * Use IDENTIFY command to resolve the server information in the
927 GETKEY command instead of INFO command. Affected file
928 lib/silcclient/command.c.
930 * All command reply functions in the client library now calls
931 the pending command reply callbacks even if an error has
932 occurred. The server has done this a long time and now it was
933 time to move the client library to this as well. Now all
934 errors can be delivered back to the pending command reply
935 callbacks if necessary. Affected files are
936 lib/silcclient/command[_reply].[ch].
938 * Change the nickname on disconnection back to the username
939 because in reconnect the server will enforce it to it anyway.
940 Affected file irssi/src/silc/core/silc-servers.c.
942 * Fixed a config file parsing bug in the Irssi SILC client.
943 Affected file irssi/src/silc/core/clientconfig.c.
945 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
947 * When printing the channel mode on JOIN, verify that the
948 channel key and channel's HMAC are valid. Affected file
949 irssi/src/silc/core/client_ops.c.
951 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
953 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
954 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
955 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
957 * Removed channel key rekey task deleting from the function
958 silc_server_save_channel_key. Affected file silcd/server.c.
959 Added explicit timeout task context instead that is used to
960 delete the task if we are registering a new task before the
961 new task has elapsed.
963 * When channel key rekey occurs the client library now saves
964 the old channel key for a short period of time (10 seconds) and
965 is able to use it in case some is still sending channel
966 messages encrypted with the old key after the rekey. Affected
967 file lib/silcclient/[idlist.h|client_channel.c].
969 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Added check to the silc_server_new_id_real to not accept
972 new ID if it is the sender's own ID. Affected file is
973 silcd/packet_receive.c.
975 * Assure that we do not announce ourself or the one we've
976 sending our announcements when we're router and are announcing
977 servers to our primary router. Affected file silcd/server.c.
979 * Fixed silc_server_command_identify_check_client to assemble
980 correct WHOIS packet. It send corrupted WHOIS packet and
981 caused problem with router to router connections. Affected
982 file silcd/command.c.
984 Fixed also silc_server_command_whois_check the same way
985 as for the IDENTIFY command.
987 * Added new SilcIDListStatus to the server in the SilcIDListData
988 structure. The status now includes the current status of
989 the entry (like registered, resolved etc.). Affected file
990 silcd/idlist.[ch]. Defined a bunch of different status types
991 as well. This replaced the old boolean registered field as well.
993 Added resolve_cmd_ident field to the SilcClientEntry structure
994 too so that if the entry is for example being resolved so
995 another command may attach to the same pending command reply
996 without requiring to resolve the same entry again. This concept
997 should optimize the WHOIS and the IDENTIFY resolving under
998 heavy load by taking away unnecessary resolving for entries
999 that are being resolved already.
1001 Added support for adding multiple pending commands for one
1002 command idenfier. Affected file silcd/command[_reply].[ch].
1004 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1005 before deleting the data. Otherwise the hash table will have
1006 freed data in comparison functions. Affected file is
1007 silcd/command_reply.c.
1009 * Fixed silc_idlist_replace_client_id to add the new entry to
1010 the cache with NULL nickname. Otherwise there will be invalid
1011 memory as the nickname after the nickname is freed. Affected
1012 file silcd/packet_receive.c.
1014 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1015 saved into wrong slots because the previous number of entries
1016 was not taken into account. Affected file silcd/idlist.c.
1017 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1019 * If we are router and we receive JOIN notify to a channel that
1020 does not have any users then notified client is marked as the
1021 channel founder, as it is it. The affected file is
1022 silcd/packet_receive.c
1024 * Added to the extended hash table API's table_del_*ext functions
1025 the destructor as argument too, so that the caller can decide
1026 which destructor to use or whether to use destructor at all.
1027 Affected file lib/silcutil/silchashtable.[ch].
1029 * Fixed ID Cache purging. It actually deleted the entries from
1030 the hash table after the data was freed. The hash table ended
1031 up comparing freed memory. The affected file is
1032 lib/silccore/silcidcache.c.
1034 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Fixed Irssi SILC client's KILL command's HELP syntax.
1038 * The USERS command now resolves the detailed user information
1039 if the userinfo field is missing. Affected file is
1040 lib/silcclient/command_reply.c.
1042 * Do not print error in silc_file_read if the read file does
1043 not exist. Just silently return NULL. Affected file is
1044 lib/silcutil/silcutil.c.
1046 * Fixed the silc_log_output to not wine about NULL filename
1047 and to not create some bogus " " filename. Affected file is
1048 lib/silcutil/silclog.c.
1050 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Fixed various printing bugs on the user interface in the
1053 Irssi SILC Client. Minor changes that were forgotten from
1056 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Fixed the configure.in.pre and the compilation and distribution
1059 environment to support the new autoconf 2.52. That version is
1060 now required to compile the CVS trunk.
1062 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1065 to generally parse user@fqdn format strings. Affected file
1066 lib/silcutil/silcutil.c.
1068 * Added nickname_format and nickname_force_format fields to the
1069 SilcClientParams structure. The first one defines the format
1070 for the nicknames that the library will enforce if the receives
1071 multiple same nicknames. The second one is boolean value and
1072 can be used to force the library to always enforce the format
1073 to the nicknames regardles whether there are multiple nicknames
1074 or not. This configurable formatting was employed to flexibly
1075 support accessing multiple nicknames from the user interface.
1076 The userinterface can now set the nicknames to what ever format
1077 they prefer. Affected file lib/silcclient/silcapi.h.
1079 Added function silc_client_nickname_format to the file
1080 lib/silcclient/idlist.c. It performs the nickname formatting.
1082 Added new field `hostname´ to the SilcClientEntry context.
1083 It holds the hostname of the client. Affected file is
1084 lib/silcclient/idlist.h.
1086 * Irssi SILC Client sets the nicknames in nick@hostn format.
1087 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1088 irssi/src/silc/core/silc-core.c.
1090 The WHOIS printing now also shows both the real nickname and
1091 the formatted nickname so that user knows how to access the
1092 user if there are multiple same nicknames cached. Affected
1093 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1094 printing formatting too to take the hostname now as a separate
1095 argument. The Affected file is
1096 irssi/src/fe-common/silc/modules-formats.[ch].
1098 * Changed the silc_client_get_clients_local to accept the formatted
1099 nickname as argument. It accepts the real nickname too but the
1100 formatted nickname can be used to find the true entry from
1101 multiple entries. Affected file lib/silcclient/silcapi.h and
1102 lib/silcclient/idlist.c.
1104 * Added nickname_format_parse field to the SilcClientParams.
1105 It is a callback function provided by the application to parse
1106 the nickname out of the formatted nickname string. The library
1107 calls it to get the nickname from the formatted string. Since
1108 the application generally knows better the format of the nickname
1109 string it parses it instead of the library, even though library
1110 encodes the formatted string. If the callback function is not
1111 provided then the library will use the string as is. The
1112 affected file is lib/silcclient/silcapi.h.
1114 * All the nickname strings passed to the client library in
1115 commands are now expected to be formatted nickname strings.
1116 If the command does not support the formatted nickname string
1117 it will assume that the sent string is the actual nickname.
1118 Affected file lib/silcclient/command.c.
1120 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Added public key authentication support to OPER and SILCOPER
1123 commands in the client library. Affected file is
1124 lib/silcclient/command.c.
1126 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Changed the get_auth_methdod client operation to be asynchronous.
1129 It can be async if the application resolves the authentication
1130 method from the server during the negotiation. Added new
1131 SilcGetAuthMeth completion callback that the application will
1132 call after resolving the authentication method.
1134 Added function silc_client_request_authentication_method that
1135 the application can use to resolve the authentication method
1136 from the server. Added also SilcConnectionAuthRequest callback
1137 that the library will call after the server has replied. The
1138 application can call this function if it does not know the
1139 current authentication method.
1141 Affected files are lib/silcclient/client.c and
1142 lib/silcclient/silcapi.h.
1144 * The Irssi SILC client now automatically resolves the authentication
1145 method incase any configuration information is not present (and
1146 currently there never is). The affected file is
1147 irssi/src/silc/core/client_ops.c.
1149 * Fixed public key authentication from the client library.
1150 Affected file lib/silcclient/protocol.c. Changed also the
1151 protocol specification about the public key authentication in
1152 the connection authentication protocol. The actual data to be
1153 signed is now computed with a hash function before signing.
1155 * Fixed the public key authentication from the server as well.
1156 Affected file silcd/protocol.c.
1158 * Removed the mlock()'s from the memory allocation routines.
1159 Affected file lib/silcutil/silcmemory.c. The ./configure does
1160 not check anymore for the mlock(). Affected file is
1163 * Fixed USERS command in server to allow the execution of the
1164 command for private and secret channels if the client sending
1165 the command is on the channel. Affected file silcd/command.c.
1167 * Fixed silc_client_get_clients_local to return the clients
1168 count correctly. It could return wrong value. Affected file
1169 lib/silcclient/idlist.c.
1171 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1174 types. The assembler optimizations seemed not to like 64-bit
1175 data types. The assmebler optimizations thus are now enabled
1176 also for BSD systems as opposed to only enable them for Linux.
1178 * Do not check for threads at all on BSD systems. Affected
1179 file configure.in.pre.
1181 * Removed -n and -h options from the Irssi SILC Client since
1182 they are not used in silc.
1184 * Fixed the prime generation to assure that the first digit
1185 of the generated random number is not zero since our conversion
1186 routines does not like number strings that starts with zero
1187 digit. If zero digit is seen the random number is regenerated.
1188 This caused some corrupted RSA keys when the zero first digit
1189 was met. Affected file lib/silcmath/silcprimegen.c.
1191 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Fixed WIN32 configuration in the ./configure script.
1194 Fixed to include xti.h on environments that has it.
1195 Patches by Carsten Ilchmann and andrew.
1197 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Changed the silc_id_create_client_id to be collision
1200 resistant. It is now assured that there cannot be created
1201 two same client ID's. I suspect that some weird bugs in
1202 the server were actually caused by duplicate Client IDs.
1203 Affected file silcd/serverid.[ch]. A router receiving
1204 new ID now also assures and informs the sending server
1205 if the ID caused collision.
1207 * Changed the silc_id_create_channel_id to also assure that
1208 there are no collisions.
1210 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Statement about ignoring the Mutual Authentication flag when
1213 performing rekey with PFS was a bit misleading. It is ignored
1214 if it was set in the initial negotiation, it cannot be even
1215 set in the rekey. Fixed in the ke-auth draft. Started the
1216 new versions of the protocol drafts in the doc/.
1218 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1220 * Fixed a bug in silc_client_command_identify_save when saving
1221 new channel information. The channel name was no duplicated
1222 and caused crash on exit. Affected file is
1223 lib/silcclient/command_reply.c.
1225 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1227 * Fixed the getkey command handling in the server. Send just
1228 empty OK reply to the sender if the key could not be fetched
1229 (but everything else was ok, like the key just was not available).
1230 Changed the public key parameter to optional in the protocol
1231 specs so that empty OK reply can be sent. Affected file
1234 Added a message to Irssi SILC client to tell to user if the
1235 server did not return a public key.
1237 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Fixed a channel key regeneration bug. It registered new
1240 timeout tasks exponentially until all system resources were
1241 used. Affected file silcd/server.c.
1243 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * Added the SILC Document generator to the scripts/silcdoc.
1246 It can be used to generate the Toolkit Reference Manual out
1247 of the source tree. Internally it will also use the RoboDoc
1248 generator now imported in util/robodoc.
1250 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Added couple of return's in rekey protocol if error orccurred
1253 during the protocol. The execution must be terminated.
1254 Affected file silcd/protocol.c. Also, terminate the protocol
1255 always with timeout.
1257 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * The client's Client ID was created initally from the wrong
1260 nickname (it could have been in format nick@host) in the
1261 silc_server_new_client. Affected file silcd/packet_receive.c
1263 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Added some SILC_LOG_ERROR's to various error conditions
1266 if client could not be added to ID cache. Affected files
1267 silcd/packet_receive.c and silcd/server.c.
1269 * When client's sock->user_data is freed, NULL also the
1270 client->router and client->connection pointers. Added check
1271 for these pointers being NULL to various places around the
1272 code. Affected file silcd/server.c.
1274 * Added client->data.registered == TRUE checks to various
1275 places around the code to assure that unregistered client's
1276 are not handled when it is not allowed. Affected file
1279 * Added `bool registered' fields to all
1280 silc_idlist_[server|client]_get_* routines to indicate whether
1281 the fetched client needs to be registered or not. Affected
1282 file silcd/idlist.[ch].
1284 * Add your own entry as registered to the ID cache in the
1285 server. Affected file server.c.
1287 * Fixed a bug in silc_server_new_server. The SilcServer was
1288 set as the new server's context instead of SilcServerEntry.
1289 This naturally caused some weird bugs.
1291 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Do not delete the channel rekey task when adding it
1294 for in silc_server_create_channel_key.
1296 * Changed the silc_server_create_channel_key to return
1297 TRUE or FALSE to indicate the success of the channel key
1300 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1302 * Fixed MSVC++ project files and added missing files to
1303 Makefiles under win32/.
1305 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Do not add TCP_NODELAY flag if the operating system
1308 does not have it defined. Affected files are
1309 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1311 * Fixed buffer overflow from Irssi SILC Client. Affected
1312 file irssi/src/fe-common/core/themes.c.
1314 * Fixed double free in client library in the file
1315 lib/silcclient/client.c when disconnecting from server.
1317 * Applied double free patch from cras to Irssi SILC client.
1318 Affected files irssi/src/core/[modules/expandos].c
1320 * Fixed the disconnection handling to Irssi SILC Client.
1321 The application must call silc_client_close_connection
1322 in ops->connect client operation in case of failure of
1323 the connection. Affected file is
1324 irssi/src/silc/core/client_ops.c.
1326 * Do not set sock->protocol to NULL in the function
1327 silc_client_close_connection after executing the protocol's
1328 final callback since the sock might not be valid anymore.
1329 Affected file lib/silcclient/client.c.
1331 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Do not enable SILC_THREADS if the linking with libpthread
1334 did not happen. Affected file configure.in.pre.
1336 * Added notion to protocol specification that server must
1337 verify the sent authentication payload with CMODE when
1338 setting the channel founder key. Implemented it to the
1339 server. Affected file silcd/command.c.
1341 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * Added _EXTRA_DIST SILC distribution variable to the
1344 distributions file. It is used to conditionally add extra
1345 files or directories to the specific distribution. Affected
1346 files ./prepare, Makefile.am.pre and distributions.
1348 Removed the `_' from the start of the distribution names.
1351 * Added README.WIN32 for instructions to compile the Toolkit
1354 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Fixed a double free in disconnection in the server. Affected
1357 file is silcd/server.c.
1359 * Fixed the lib/silcske/groups.c to work now also with GMP
1360 MP library. The string conversion did not work when using
1361 specific base and the base is indicated in the string as well.
1363 * Created win32/ directory which now includes MSVC++ specific
1364 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1365 It will appear only in the toolkit distribution
1367 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Changed the key material distribution function in case when
1370 the hash output is too short. The data is now concatenated
1371 a bit differently than it used to. Made the change to the
1372 SKE protocol specification.
1374 * Added better GMP detection to configure.in.pre. A patch
1377 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Fixed a minor bug in SKE that might cause some problem on
1380 some platforms. Affected file lib/silcske/silcske.c.
1382 * Added the cookie checking for initiator in the SKE. It checks
1383 that the responder returns the sent cookie unmodified. The
1384 affected file is lib/silcske/silcske.c. Added new SKE
1385 error type INVALID_COOKIE that can be sent during the
1386 negotiation. Fixed some memory leaks as well.
1388 * Added the "invalid cookie" error message to Irssi SILC client's
1391 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Added `task_max' field to the SilcClientParams to indicate
1394 the maximum tasks the scheduler can handle. If set to zero,
1395 default values are used. Affected file lib/silcclient/silcapi.h.
1397 * Fixed memory leaks in silc_client_close_connection. Affected
1398 file lib/silcclient/client.c.
1400 * Added silc_client_del_client_entry to client library to free
1401 all memory of given client entry. Affected file is
1402 lib/silcclient/idlist.[ch].
1404 * Added new functions silc_client_del_channel and
1405 silc_client_del_server to delete channel and server entries.
1406 Affected file lib/silcclient/[silcapi.h/idlist.c].
1408 * Removed silc_client_del_client_by_id from silcapi.h.
1410 * Fixed the INFO command to return the server's own info
1411 correctly when querying by Server ID. Affected file is
1414 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Removed the non-blocking settings in WIN32 code in the
1417 silc_sock_[read/write] and added SleepEx instead. Affected
1418 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1419 of input data is now checked with FIONREAD and ioctlsocket.
1421 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Call silc_schedule_task_del_by_context in the
1424 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1425 Affected file lib/silccore/silcprotocol.c.
1427 * Call silc_protocol_cancel for active protocols in the
1428 silc_server_close_connection if the funtion
1429 silc_server_free_sock_user_data has not been called.
1430 Affected file silcd/server.c.
1432 * Generic tasks cannot be deleted using the del_by_fd
1433 task deleting function since generic tasks does not match
1434 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1436 * Added a notion to SILCOPER help file that the SILCOPER works
1437 only on router server, not on normal server.
1439 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Added for WIN32 support for the new scheduler as well.
1442 Affected file lib/silcutil/win32/silcwin32schedule.c.
1444 * Fixed the SHA1 implementation to work on various platforms.
1446 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1449 API. It is part of the scheduler now. Everything else is
1450 as previously but some functions has changed their names.
1451 Checkout the lib/silcutil/silcschedule.h for the interface.
1452 Updated all applications to use the new interface. Affected
1453 files are lib/silcutil/silcschedule.[ch].
1455 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Found a bug in the SKE implementation. The HASH value,
1458 specified by the protocol, was not computed correctly. The
1459 public key of the responder was not added to the computation
1460 even though it is mandatory. Affected file lib/silcske/silcske.c.
1461 This unfortunately causes incompatibilities with older
1462 clients and servers.
1464 * Added WIN32 specific network init and uninit functions:
1465 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1466 the Winsock2. Affected file lib/silcutil/silcnet.h and
1467 lib/silcutil/win32/silcwin32net.c.
1469 * Set the socket always to nonblocking mode on WIN32 after
1470 reading data or writing data. Affected file is
1471 lib/silcutil/win32/silcwin32sockconn.c.
1473 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1475 * Fixed various compilation problems under WIN32. Affected
1476 files lib/silcutil/win32/silcwin32thread.c and
1477 lib/silcutil/win32/silcwin32schedule.c.
1479 * Removed all _internal.h #includes from public header
1480 files. Internal headers must never be included from
1483 Removed also the lib/silcske/payload_internal.h file.
1485 * All include files that may be needed (public and some others
1486 included by the public headers) by application developers are
1487 now copied to the ./includes directory. It does not copy any
1488 internal headers. Affected file Makefile.defines.pre and all
1489 Makefile.am's under lib/ and subdirs.
1491 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Do not change the ~/.silc directory's permissions automatically.
1494 Affected file irssi/src/silc/core/clientutil.c.
1496 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Do not cancel the protocol in silc_server_close_connection
1499 it might cause recursion. Now cancelled in the function
1500 silc_server_free_sock_user_data. Affected file silcd/server.c.
1502 * Fixed the silc_server_remove_clients_by_server to regenerate
1503 the channel keys correctly finally. Added also new function
1504 silc_server_remove_clients_channels to actually do it.
1505 Affected file silcd/server.c.
1507 * Fixed the silc_server_new_channel to not crash by giving
1508 wrong router to the new channel. Affected file is
1509 silcd/packet_receive.c.
1511 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1514 which is given as argument to the silc_client_alloc now.
1515 It can be used to configure the client and set various parameters
1516 that affect the function of the client.
1518 * The USERS command in server did not check whether the channel
1519 is private or secret. Affected file silcd/command.c.
1521 * Added new argument to the USERS command in protocol specification.
1522 The USERS command now can take the channel name as argument
1523 as well. Added support for this in client and server and
1524 updated the protocol specs.
1526 * Completed the GETKEY command in client. It can be now used
1527 to fetch also servers public key not only some clients.
1528 Affected files lib/silcclient/command[_reply].c.
1530 * Added silc_client_get_server to return server entry by the
1531 server name. Affected files lib/silcclient/silcapi.h and
1534 * Redefined the IDENTIFY command in protocol specification to be
1535 more generic. It now can be used to query information about
1536 any entity in the SILC Network, including clients, servers and
1537 channels. The query may be based either the entity's name
1538 or the ID. Added support for this in both client and server.
1540 Affected files silcd/command.c and lib/silcclient/command.c
1541 and command_reply.c.
1543 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1544 the _from_client and _from_server functions. Affected file
1547 * Added silc_client_get_channel_by_id_resolve to the file
1548 lib/silcclient/silcapi.h to resolve channel information by
1549 its ID. Added also silc_client_get_channel_by_id that
1550 does not resolve it from the server.
1552 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Added SilcServerEntry context into the client library
1555 to represent one server. The INFO command now allocates
1556 these to save the resolved server info. For now on the
1557 client library will also keep information about servers,
1558 connected and resolved with INFO.
1560 The INFO command now allocates the SilcServerEntry context
1561 and saves the server info there. The COMMAND_REPLY in
1562 the INFO now returns the parameters to application in
1563 same order as defined in the protocol specification.
1565 The entries are cached in the client->server_cache.
1567 * The INFO command is now issued after received the Client ID
1568 from the server. Affected file lib/silcclient/client.c.
1570 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1571 to the application as the mode changer might be server.
1572 It is guaranteed that NULL is not returned anymore to the
1573 application. Affected file lib/silcclient/client_notify.c.
1575 The ID Type is now also passed to the application so that
1576 it can check whether the returned entry is SilcClientEntry
1579 Added new function silc_client_get_server_by_id to return
1580 the server entry by ID. Affected files are the
1581 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1583 * Do not create the channel in the Irssi SILC Client when issuing
1584 the JOIN command but when received the sucessful JOIN command
1585 reply. Otherwise the channel might get created even though we
1586 could not join it. The Affected file is
1587 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1589 * Fixed a channel joining bug in router. The router must also
1590 check the channel modes, invite and ban lists etc. when serving
1591 the JOIN command sent by normal server. Affected file is
1592 silcd/command.c. The router now resolves the client's
1593 information from the server who sent the JOIN command if it
1594 does not know it, and processes the JOIN command only after
1597 * Changed the SilcCommandCb to take new argument; void *context2.
1598 Affected file lib/silccore/silccommand.h
1600 The second argument in the command callbacks in the server now
1601 includes the SilcServerCommandReplyContext if the command was
1602 called as pending command callback from the command reply.
1603 Otherwise it is NULL. When called as pending the status of the
1604 command reply will be checked and if it was erronous the
1605 error will be sent to the original sender of the command.
1606 This way the client always receives the error messages even
1607 though the server was actually the one who received the error
1608 when it resent the command to router, for example. Affected
1609 files silcd/command[_reply].[ch].
1611 * Fixed sending WHOWAS command's error message to client if
1612 the requested client could not be found. It was missing.
1615 * Changed the CMODE and CUMODE commands reply arguments in the
1616 protocol specification. The Channel ID is now sent in both
1617 of the commands to identify the channel. Implemented this
1618 new feature to the client and server. Affected files
1619 lib/silcclient/command_reply.c and silcd/command.c.
1621 * Made better checks for invite and ban lists in the JOIN
1622 command in server. Affected file silcd/command.c.
1624 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * The server now performs the incoming host IP/DNS lookup
1627 using the silc_socket_host_lookup and thus does not block
1628 the server anymore. Affected file silcd/server.c.
1630 * Completed the multi-thread support for SILC Scheduler in
1631 the lib/silcutil/silcschedule.c.
1633 * Fixed the configure.in.pre to detect the pthread correctly
1636 * Fixed a deadlock in silc_task_queue_wakeup in the file
1637 lib/silcutil/silctask.c.
1639 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Added new function silc_schedule_wakeup that is used in
1642 multi-threaded environment to wakeup the main thread's
1643 schduler. It needs to be used when a thread adds a new task
1644 or removes a task from task queues. After waking up, the
1645 scheduler will detect the task queue changes. If threads
1646 support is not compiled in this function has no effect.
1647 Implemented the wakeup mechanism to both Unix and WIN32
1648 systems. Affected files are lib/silcutil/silcschedule.[ch],
1649 lib/silcutil/unix/silcunixschedule.c and the
1650 lib/silcutil/win32/silcwin32schedule.c.
1652 * Added new function silc_task_queue_wakeup to wakeup the
1653 scheduler by the specified task queue. Affected file
1654 lib/silcutil/silctask.[ch].
1656 * The silc_socket_host_lookup_start now wakes up the scheduler
1657 after adding the timeout task. Affected file is
1658 lib/silcutil/silcsockconn.c.
1660 * The silc_socket_host_lookup is synchronous now if the threads
1661 support is not compiled in. However, the callback is still
1662 called asyncronously through the scheduler, anyway. Affected
1663 file lib/silcutil/silcsockconn.c.
1665 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added new function silc_socket_host_lookup to perform
1668 asynchronous IP and FQDN lookups for the socket connection.
1669 Affected files lib/silcutil/silcsockconn.[ch].
1671 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1674 that may or may not compile the mutex support in.
1676 Changed the silc_mutex_alloc interface. It allocates the
1677 mutex now to the sent pointer and returns TRUE or FALSE.
1679 Affected file lib/silcutil/silcmutex.h.
1681 * Wrote the SILC Task Queue interface to support multi-threads.
1682 Affected file lib/silcutil/silctask.[ch].
1684 * Wrote the SILC Scheduler to support multi-threads. Affected
1685 file lib/silcutil/silcschedule.c.
1687 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1690 in lib/silcutil/win32/.
1692 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Defined SILC Mutex API and SILC Thread API and implemented
1695 them for Unix. Affected files are
1696 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1697 lib/silcutil/unix/silcunixmutex.c and
1698 lib/silcutil/unix/silcunixthread.c.
1700 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1702 * Fixed the silc_server_remove_clients_by_server's channel
1703 key re-generation. The hash table handling was incorrect
1704 and would not work with many channels. Affected file is
1707 * Fixed some memory leaks around the server code.
1709 * Rewrote the silc_server_get_users_on_channel to support IPv6
1710 based Client ID's. Affected file silcd/server.c.
1712 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1713 specification. However, a separate document must be written
1714 to define the detailed signing procedure and the payload
1715 associated with the flag. Defined the flag to the
1716 lib/silccore/silcchannel.h as well.
1718 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Changed the dynamic tables to static size tables in the
1721 lib/silccrypt/silchmac.c.
1723 * Removed GCC dependencies from the code. A patch by cras.
1725 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1727 * Do not show the error "Error receiving packet bla bla"
1728 in server if it really was not an error (-2 means that reading
1729 is pending). Affected file silcd/server.c.
1731 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Fixed a possible crash in silc_server_remove_clients_by_server
1734 in silcd/server.c. Fixed there also some memory leaks.
1736 * Fixed the silc_idlist_replace_client_id. It could replace
1737 wrong key in the hash table. Affected file silcd/idlist.c.
1739 * Do not check whether there are global users on the channel
1740 if the channel->global_users is FALSE. Affected functions
1741 silc_server_remove_from_one_channel and
1742 silc_server_remove_from_channels in silcd/server.c. Also,
1743 do not check if the removed client is local as we can be
1744 sure that global client was not removed from the channel
1745 and checking for global users is not needed.
1747 * The silc_server_remove_clients_by_server now re-generates
1748 the channel keys correctly for those channels that had
1749 clients removed from them. Affected file silcd/server.c.
1751 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Found the reason of random crashes in the server. We weren't
1754 ignoring the SIGPIPE signal (which can be sent in write())
1755 and it crashed the server. Affected file silcd/silcd.c.
1757 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Assure that sock->user_data is not NULL in the function
1760 silc_server_packet_send in silcd/packet_send.c.
1762 * Disconnect the remote connection if it could not be added
1763 to any ID lists in the server. The affected file is
1766 * Check in silc_server_packet_send[_real/dest] that the
1767 socket is not disconnecting and ignore the data if it is.
1768 Affected file silcd/packet_send.c.
1770 * Define inline to __inline on native WIN32 compilation.
1771 Affected file includes/silcwin32.h.
1773 * Added some explicit type casts for inline code since MSVC
1774 require them. Affected files lib/silcutil/silcbuffer.h,
1775 lib/trq/silcdlist.h and lib/trq/silclist.h.
1777 * Print warning in log files from now on if the packet
1778 decryption fails. Affected file silcd/server.c.
1780 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Changed the `say' client operation's interface to accept
1783 new `type' argument to indicate the type of the message sent
1784 by the library. The application may filter the library's
1785 messages according the type. The affected file is the
1786 lib/silcclient/silcapi.h.
1788 * Added two new functions to lib/silcclient/silcapi.h:
1789 silc_client_del_client and silc_client_del_client_by_id.
1790 Affected file lib/silcclient/idlist.c.
1792 * Moved the clientincludes.h from includes/ to silc/ and
1793 serverincludes.h from includes/ to silcd/.
1795 * The modes for the CMODE and CUMODE are now passed as
1796 uint32 for application with COMMAND_REPLY. The affected
1797 file is lib/silcclient/command_reply.c.
1799 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * /WHOIS without arguments shows client's own information.
1802 Affected file lib/silcclient/command.c.
1804 * Changed PING to not accept any arguments. The specs
1805 says that client can ping only the connected server so
1806 requiring an argument is not needed. Affected file is
1807 lib/silcclient/command.c.
1809 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Fixed a fatal bug in private message sending and reception
1812 encryption and decryption when using private message keys.
1813 The implementation was incorrect and did not follow the
1814 specification. It causd that some of the message were
1815 lost since it did not use the sending and receiving keys
1816 as the protocol suggests. This has been fixed and will cause
1817 incompatibilities with older clients when sending private
1818 message encrypted with private message keys. Affected files
1819 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1820 and various other in Irssi SILC Client.
1822 Added `responder' boolean argument to the functions
1823 silc_client_add_private_message_key[_ske] to indicate when
1824 the key is added as responder or initiator of the key
1827 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Removed the silc_ske_check_version function and created
1830 a SilcSKECheckVersion callback. Added also a function
1831 silc_ske_set_callbacks that is now used to set all SKE
1832 callbacks. The callback functions are not given to
1833 the SKE functions anymore, but this function is used to
1836 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1838 * Added `silc_version' argument to the silc_client_alloc
1839 to define the version of the application for the library.
1840 The library will use the version string to compare it
1841 against the remote host's (usually a server) version
1842 string. Affected file lib/silcclient/silcapi.h
1844 * Added the KE protocol context to Key Agreement context
1845 in client library so that we can abort the SKE if it
1846 is in process when we get timeout. Affected file is
1847 lib/silcclient/client_keyagr.c.
1849 * Do not resolve the client ID forever if it returns in the
1850 first time that such client does not exist. This was done
1851 for example with private message. Affected file is
1852 lib/silcclient/client_prvmsg.c.
1854 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Do not add regex.h for WIN32. The affected file
1857 includes/silcincludes.h.
1859 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1860 not work yet 100%. It generates the DLL's automatically
1861 when compiling with --with-win32 under cygwin.
1863 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * lib/contrib/regex.c is not compiled on WIN32.
1867 * Added silc_net_get_socket_opt function to the
1868 lib/silcutil/silcnet.h.
1870 * Added includes/silcwin32.h for WIN32 specific includes
1873 * Do not use ptime structure or any of the posix process
1874 functions on WIN32 in lib/silccrypt/silrng.c.
1876 * Added silc_gettimeofday to provide generic function
1877 for struct timeval on all platforms. Added the function
1878 to lib/silcutil/silcutil.h.
1880 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1882 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1883 library as they clearly belong there. As a plus side we
1884 can make the actual socket connection routines platform
1887 Added also new generic function silc_socket_read and
1888 silc_socket_write (that used to be silc_packet_[read/write].
1889 The implementation of these are platform specific.
1891 * Added WIN32 specific routines of silc_socket_[read/write]
1892 to lib/silcutil/win32/silcwin32sockconn.c.
1894 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * Added preliminary support for native WIN32 compilation under
1897 cygwin (using the -mno-cygwin option for GCC) to the
1898 ./configure.in.pre. The --with-win32 now prepares the
1899 compilation for native WIN32.
1901 * Rewrote the SILC Scheduler interface in the file
1902 lib/silcutil/silcschedule.h. The scheduler is now context
1903 based and does not have anymore any global static scheduler.
1904 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1905 and created lib/silcutil/win32 directory for WIN32 based
1908 * Added Unix specific network routines to the
1909 lib/silcutil/unix/silcunixnet.c and the old
1910 lib/silcutil/silcnet.c includes now only generic routines.
1912 Added WIN32 specific network routines to the
1913 lib/silcutil/win32/silcwin32net.c.
1915 * Added Unix specific utility functions from the
1916 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1918 * Added WIN32 SILC Scheduler to the file
1919 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1922 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Do not handle JOIN notify in the server if the target client
1925 is not registered (idata->registered == FALSE). The affected
1926 file is silcd/packet_receive.c.
1928 * Update the nickrec->founder in event_cumode in the Irssi SILC
1929 client. Affected file irssi/src/silc/core/silc-channels.c.
1931 * Fixed the CUMODE_CHANGE notify handling in the server when
1932 server and router are announcing their clients on channels.
1933 Now the mode changes are saved and notified correctly. The
1934 affected file is /silcd/packet_receive.c.
1936 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1937 They really did not replace the cache entry in the ID Cache.
1938 Now they do that. Affected file silcd/idlist.c.
1940 * Fixed the KICK notify handling in the Irssi SILC client to
1941 update the channel records so that the kicked client does not
1942 appear to be on the channel. The affected file is
1943 irssi/src/silc/core/silc-channels.c.
1945 * Always update the conn->current_channel when executing command
1946 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1948 * Fixed the KILL notify handling in Irssi SILC client to remove
1949 the killed client on all channels.
1951 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Fixed the silc_parse_command_line to remove extra spaces
1954 from the start and end of the arguments. Affected file is
1955 lib/silcutil/silcutil.c.
1957 * Cancel and free any active protocol in the function
1958 silc_server_close_connection. Affected file silcd/server.c.
1960 * Cancel and free any active protocol in the function
1961 silc_client_close_connction. Affected file is
1962 lib/silcclient/client.c.
1964 * Do not execute the KILL command for clients that are in
1965 history (ie. they are not in the network). Affected file is
1968 * Fixed KILL notify handling, client does not crash anymore.
1969 Affected file irssi/src/silc/core/silc-channels.c.
1971 * Reduced the default packet buffer size from 2048 to 1024 in
1972 lib/silccore/silcpacket.c.
1974 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1975 counter to the SKE context that is incresed when the SKE library
1976 performs async operation outside the library. If the outside
1977 process frees the SKE context and FREED status will be set
1978 and the library will detect after the sync operation that the
1979 libary is freed. The affected files are
1980 lib/silcske/silcske[_status].[ch].
1982 * Resolve the client entry information in the function
1983 silc_client_channel_message to assure that NULL pointer is not
1984 passed as client entry to the application. */
1986 * Fixed the task timeout calculation to assure that there is
1987 never negative timeouts. The affected file is
1988 lib/silcutil/silcschedule.c.
1990 * Fixed the channel user mode notification sending in server.
1991 It was sent point-to-point to the router (or to server by router)
1992 but it needs to be destined to a channel. The routines now
1993 supports sending the channel user mode notifys to the channels
1994 when announcing clients and channels. Affected files are
1995 silcd/server.c and silcd/packet_receive.c.
1997 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1998 It did not actually replace the old channel entry in the cache.
1999 Affected file lib/silcclient/client_notify.c.
2001 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Fixed a possible crash in silc_packet_send_prepare. It now
2004 assures always that there is enough space in the buffer and
2005 at the tail area of the buffer (for MAC).
2007 Fixed the inbound buffer reallocation in silc_packet_read.
2008 It was old code and did not handle the reallocation correctly.
2011 The affected file is lib/silccore/silcpacket.c.
2013 * Fixed buffer overflow in silc_parse_nickname in the file
2014 lib/silcutil/silcutil.c.
2016 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * make install generates new server keys only if there is not
2021 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2024 Added check that if the NOREPLY is set then we will not send
2025 the away message. This avoids infinite loop of away messages
2026 if both clients are away. The affected file is
2027 lib/silcclient/client_prvmsg.c.
2029 * Fixed client crash if /NICK was given without arguments.
2030 Affected file lib/silcclient/command.c.
2032 * Server does not send the invite list in INVITE command back
2033 to the client if the list was not altered. Added this notion
2034 to the protocol spec as well. Affected file silcd/command.c.
2036 Fixed possible crash in INVITE command by checking the
2037 value of silc_server_get_client_route command.
2039 * Fixed the INVITE notify type handling. The arguments are now
2040 taken in correct order and client does not crash. The affected
2041 file is irssi/src/silc/core/silc-channels.c.
2043 Removed the "Inviting xxx to channel" message from the
2044 client library away and let the application handle it.
2045 Affected file lib/silcclient/command.c. Added that message
2046 to Irssi SILC client's message formats.
2048 * Fixed CMODE command crash in client. It now checks the
2049 amount of arguments correctly and does not crash. The affected
2050 file is lib/silcclient/command.c.
2052 * Do not create new channel automatically in silc_channels_join
2053 but check whether the channel by that name already exists.
2054 Affected file irssi/silc/core/silc-channels.c.
2056 * Do not send the SERVER_SIGNOFF to router if the disconnected
2057 entity was the router. Affected file silcd/server.c.
2059 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2060 SILC client as it was missing from there.
2062 Added the handling of the KICK notify to the Irssi SILC client
2063 as it was missing. Added "you have been kicked" message to
2064 Irssi SILC client's message modules formats.
2066 Added the handing of the KILL notify to the Irssi SILC client
2067 as it was missing. Added the kill message module formats
2070 The affected file is irssi/src/silc/core/silc-channels.c.
2072 * The router did not save the channel mode the server announced.
2073 Affected file silcd/packet_receive.c.
2075 * Fixed a possible crash in INFO command in server. If the
2076 server did not provide the server info it crashed. Affected
2077 file silcd/command.c.
2079 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Fixed the GETKEY command in the server to check also the
2082 global list. Otherwise the GETKEY would not work correctly
2083 in normal SILC server. Affected file silcd/command.c.
2085 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * Fixed GETKEY crash, it crashed if the command did not succseed.
2089 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2092 is now real and not just an macro interface to GMP.
2094 Removed the entire GMP from the source tree and imported new
2095 NSS MPI library instead. Reason for removing GMP is that it is
2096 extremely large and compiles extremely slow. The NSS MPI
2097 is only a few files and compiles in less than 10 seconds.
2098 The speed is also about the same as GMP. The MPI is imported
2099 to lib/silcmath/mpi.
2101 If the system has GMP installed we will still use the GMP.
2102 If it is not then the NSS MPI will be compiled.
2104 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Merged a long nickname (127 characters long) crash bugfix from
2107 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2109 * Merged a freed memory reference bugfix from Irssi CVS tree.
2110 Affected file irssi/src/core/commands.c.
2112 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2114 * Added the server's public key sving and verification to the
2115 server when performing the SKE. This was missing and the
2116 remote server's (or router's) public key was accepted without
2117 checking whether we have it previously or trust it at all.
2118 Affected file silcd/protocol.c.
2120 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Check in the silc_server_timeout_remote if protocol is active
2123 and make sure that the protocol's final callback is called so
2124 that all memory if freed. Affected file silcd/server.c.
2126 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * silc_server_whois_send_reply crashed the server if the nickname
2129 was 127 characters long. Affected file silcd/command.c.
2131 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Added sanity check to the silc_server_new_client. If the hostname
2134 is provided inside username then check that the provided hostname
2135 really is the same as the resolved one. If the hostname was not
2136 resolved then check it from the public key. Affected file is
2137 silcd/packet_receive.c.
2139 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2140 if the server disconnected us and the connection is not valid
2141 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2143 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2144 the library to the lib/silcutil/silcutil.[ch].
2146 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Close log file after open. Affected file
2149 lib/silcutil/silclog.c.
2151 * Check whether sock == NULL in silc_client_send_packet and return
2152 if it is. Affected file lib/silcclient/silcclient.c.
2154 * Check rec->entry == NULL in the Irssi SILC Client before
2155 sending the channel message. Affecte file is
2156 irssi/src/silc/core/silc-servers.c.
2158 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Merged a splitted window bugfix from Irssi CVS tree. The
2161 affected file is irssi/src/fe-text/textbuffer-view.c.
2163 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2164 It did not print nickname.
2166 * Improved the distributions system a bit.
2168 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2171 irssi/src/fe-text/gui-window.c.
2173 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2174 to in-active server. The affected file is
2175 irssi/src/silc/core/client_ops.c.
2177 * Resolve the client in USERS command reply if the entry does
2178 not have username resolved. The affected file is
2179 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2180 command to WHOIS command to really resolve stuff. The USERS
2181 is not used any more in any critical section so WHOIS can
2182 be used even though it might be slower than IDENTIFY.
2184 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2187 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Changed the protocol API a bit more consistent in the
2190 lib/silccore/silcprotocol.[ch].
2192 * Changed the following headers to ROBODoc format:
2194 lib/silccore/silcpayload.h
2195 lib/silccore/silcprotocol.h
2196 lib/silccore/silcsockconn.h
2198 All core library headers are now formatted.
2200 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Fixed a bug in Irssi SILC client; do not show that you are
2203 server/router operator if you really are not. Affected file is
2204 irssi/src/silc/core/client_ops.c.
2206 * Renamed silc_command_free_payload to silc_command_payload_free.
2207 Affected file lib/silccore/silccommand.h
2209 * Added silcmath.h to include the prototoypes of various routines
2210 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2213 * Changed the following headers to ROBODoc format:
2215 lib/silccore/silcchannel.h
2216 lib/silccore/silccommand.h
2217 lib/silccore/silcid.h
2218 lib/silccore/silcidcache.h
2219 lib/silccore/silcmode.h
2220 lib/silccore/silcnotify.h
2221 lib/silccore/silcpacket.h
2222 lib/silcmath/silcmath.h
2224 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Added checking to the server code not to start the server if
2227 ciphers and stuff are not configured properly. Affected files
2228 silcd/serverconfig.[h] and silcd/server.c.
2230 * Changed the layout of the header files of the public interfaces
2231 in the SILC libraries. The new layout supports ROBODoc
2232 documentation tool (and some others) so that it is easy to create
2233 a library reference manual. All the other headers and source
2234 code must still follow the CodingStyle document. Also source
2235 code must not include these ROBODoc stuffs, only the headers.
2236 Furthermore, all public interface headers must now be named
2237 by using `silc' prefix, example: silcapi.h, silccipher.h.
2238 Some files were renamed due to this. All the other headers
2239 must not be used as public interfaces. I will update the
2240 CodingStyle document later. Changed following headers, so far:
2242 lib/silcclient/silcapi.h
2243 lib/silccore/silcauth.h
2244 lib/silccore/silcprivate.h
2245 lib/silccrypt/silcdh.h
2247 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2251 * Removed silc_client_packet_send_flush from the client library
2252 as it is not needed. Affected file lib/silcclient/client.[ch].
2254 * Added printing of message of unresolved authentication method
2255 to the Irssi SILC client. Added it to the module formats.
2256 Removed the same message from the client library.
2258 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Added new distribution feature, DISTLABEL. Every distribution
2261 can define own preprocessor label that can be used in the
2262 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2263 file distributions, acconfig.h.pre and prepare.
2265 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Added Makefile.defines_int to include the actual definitions
2268 for Makefile.defines.in. Tested the new distribution system,
2269 created distributions and tested installation.
2271 * Added AWAY message printing to the Irssi SILC client. Added
2272 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2274 * Added SCONNECT command to call the SILC's CONNECT command.
2275 Cannot use CONNECT directly since Irssi uses that internally.
2276 Affected file irssi/src/silc/core/silc-servers.c.
2278 Added ACTION local command. It is same as ME command but takes
2279 the channel as mandatory argument.
2281 Rewrote some of the Irssi's help files to suite for SILC
2284 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Added Makefile.defines[.in] that should for now on be included
2287 in all Makefile.am file in the source tree. That file includes
2288 all common compilation definitions for SILC source tree.
2290 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Minor changes to the ./prepare script to change the package
2293 name according the distribution name to the configure.in.
2295 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Created new distribution system. Added file `distributions'
2298 that defines all the distributions that can be created out of
2299 the SILC source tree. The ./prepare script now reads that
2300 file to determine how to prepare the distributions. The
2301 first argument to the ./prepare is the name of the distribution
2302 and second is the version of the distribution. If given
2303 without arguments it creates the default (toolkit) distribution
2304 with the default version (defined in ./prepare).
2306 All Makefile.am files that are subject to the distributions
2307 are now named as Makefile.am.pre. These are ./Makefile.am
2308 and lib/Makefile.am. Others may be changed later.
2310 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Added invite list, ban list, some key management and connection
2313 error message printing to module formats in the Irssi SILC client.
2315 * Added new silc_client_set_away_message to set the away message
2316 that is back to the person who sent private message. The
2317 affected file lib/silcclient/silcapi.h and the
2318 lib/silcclient/client_prvmsg.c.
2320 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Fixed the private message sending in the Irssi SILC client,
2323 added local command KEY to the Irssi SILC client.
2325 Added key management and key agreement message formats to the
2326 irssi/src/fe-common/silc/module-formats.[ch].
2328 Added USERS (alias WHO) printing, server/router operator
2329 indication and LIST command printing to the module formats.
2331 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Fixed channel joining notify handling, cumode notify handling
2334 from Irssi SILC client.
2336 * Added SILC specific module-formats to the Irssi SILC client so
2337 that SILC specific message hilighting, colors etc is possible.
2338 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2340 Added channel mode, channel user mode, actions, notices,
2341 whois and whowas printing to the the module-formats.c.
2343 * Fixed a bug in channel deletion in the server. The channel
2344 is not left to the cache even if the channel founder auth mode
2345 is set when there are no users anymore on the channel. Affected
2346 file silcd/server.c.
2348 * The silc_net_localhost now resolves the entire hostname including
2349 the domain name. Affected file lib/silcutil/silcnet.c.
2351 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Changed the ask_passphrase client operation to be ascynchronous.
2354 It has now a completion callback and a context that the
2355 application must call after it has got the passphrase from
2356 the user. Affected files lib/silcclient/silcapi.h,
2357 lib/silcclient/protocol.c, lib/silcclient/command.c and
2360 Added SilcAskPassphrase callback that the application calls
2361 to deliver the passphrase to the library.
2363 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2364 The public key verification and especially a certificate
2365 verification is asynchronous procedure.
2367 Added new SILC_SKE_STATUS_PENDING status to indicate the
2368 request is pending and a callback will be called to finalize
2371 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2372 indicate that remote end did not send its public key (or
2373 certificate), even though we require it. Added check for this
2374 condition in the SKE. This was a security bug, now fixed.
2376 Defined new SilcSKEVerifyCbCompletion callback that is called
2377 when the verification process is completed.
2379 The affected files lib/silcske/silcske_status.h and
2380 lib/silcske/silcske.[ch].
2382 * Changed the verify_public_key client operation to be async
2383 as well. Defined SilcVerifyPublicKey callback that is used to
2384 indicate the success of the public key verification process.
2386 Changed the server and client to use the new async client
2389 * Changed the Irssi SILC client's internal scheduler to be called
2390 twice as many times as it used to be. As a result the client
2391 should be a bit faster now. Affected file is
2392 irssi/src/silc/core/silc-core.c.
2394 * Added support to Irssi SILC client of asynchronous public key
2395 verification and passphrase inquiry. Affected file is
2396 irssi/src/silc/core/silc-core.c.
2398 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Do not say "You have left channel %s" in client library.
2401 Moved it to the application. Affected files are
2402 lib/silcclient/command.c and silc/client_ops.c.
2404 * Fixed silc_client_get_clients. Command context was not
2405 duplicated and was freed memory in the callback. Affected
2406 file lib/silcclient/idlist.c.
2408 * Do not say "you are now talking..." on JOIN command in the
2409 client library. The appliation must handle it.
2411 * Do not say ".. changed topic to" in command reply in the
2412 client libary. The application must handle it.
2414 * Fixed TOPIC command sending in the client library.
2416 * Fixed a memory leak in silc_client_command_free in the file
2417 lib/silcclient/command.c.
2419 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Imported a modified version of Irssi client to the source tree.
2422 The Irssi will be used to create a new client called
2423 Irssi SILC. Imported to irssi/.
2425 Added silc_core_init_finish function to the Irssi. Affected
2426 file irssi/configure.in.
2428 A lot changes in the Makefile.ams around the irssi tree.
2430 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Do not rehash if the new size is same as the old size of the
2433 hash table, in the silc_hash_table_rehash*. The affected file
2434 lib/silcutil/silchashtable.c.
2436 * Replaced hash_table_del_by_context calls from the server
2437 (when channel->user_list and client->channels) to the
2438 hash_table_del as it is sufficient and faster.
2440 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Added silc_hash_table_list, silc_hash_table_get and the
2443 SilcHashTableList structure to provide an alternative way to
2444 traverse the hash table. The affected files are
2445 lib/silcutil/silchashtable.[ch].
2447 * Changed the server's idlist routines to use the hash table
2448 routines to optimize the code.
2450 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Replaced the client entry's `channel' list and channel entry's
2453 `user_list' list to hash tables for optimized lookup. Changed
2454 the code to use the hash table interface around the code.
2455 Affected file lib/silcd/idlist.[ch].
2457 * Added `auto_rehash' boolean argument to the function
2458 silc_hash_table_alloc to indicate whether the hash table should
2459 auto-rehash when it thinks is appropriate time. It will
2460 increase the hash table size if the there is twice as much
2461 entries in the table than the size of the table, and will
2462 decrease the size if there are twice as less entries than
2463 the size of the table.
2465 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2469 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2471 * silc_idcache_purge_by_context deletes the entry now by context
2472 as it is supposed to do. Affected file lib/silccore/idcache.c.
2474 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2475 client is not anymore valid (WHOWAS givens the info) and not
2476 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2478 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Removed the `data' and `data_len' arguments from the ID Cache
2481 interfaces and added `name' argument. ID Cache does not handle
2482 anymore the binary data only a names associated with given ID.
2484 * When hashing a Client ID with silc_hash_id the entire ID is
2485 not hashed anymore, instead only the hash of the Client ID is
2486 hashed. This way we can access the Client ID from the cache
2487 with Client ID but with the hash of the ID (which is a hash of
2488 the nickname) as well without any difference in performance.
2490 Added also silc_idcache_find_by_id_one_ext to do one on one
2491 searching when we have the actual ID. Added also function
2492 silc_hash_client_id_compare. The affected files are
2493 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2495 * When hashing the name associated with a ID it is always done
2496 in lowercase. This way we can access the cache without worrying
2497 about case-sensitivity, even though, for example nicknames are
2500 * Fixed a bug in server with channel message sending. It put
2501 wrong ID type as destination ID. The affected file
2502 silcd/packet_send.c.
2504 * silc_idcache_del_by_context now deletes from all hash tables
2505 by context. Affected file lib/silccore/idcache.c.
2507 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2509 * Changed the client library to use the new ID Cache interface.
2510 Changes around the source tree.
2512 * Added silc_hash_table_rehash_ext to rehash with specific
2513 hash function. Affected file lib/silcutil/silchashtable.[ch].
2515 * Added silc_hash_string_compare to compare two strings in the
2516 hash table. Affected file lib/silcutil/silcutil.[ch].
2518 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Added new function silc_idcache_del_by_context into the
2521 lib/silccore/idcache.[ch].
2523 * Changed the server's ID list routines to use the new ID Cache
2524 interface. Changes around the source tree.
2526 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Added silc_hash_table_del[_by_context]_ext functions in to the
2529 lib/silcutil/silchashtable.[ch].
2531 Removed silc_hash_table_find_all* routines and added new
2532 silc_hash_table_find_foreach to replace them.
2534 Added silc_hash_table_replace_ext function as extended
2535 replacing function. Separated the simple hash table interface
2536 from the extended hash table interface in the file
2537 lib/silcutil/silchashtable.h.
2539 * Fixed minor bugs and changed it to use some of the new
2540 hash table functions in lib/silccore/idcache.c
2542 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Added new function silc_hash_table_find_all to return all keys
2545 in the hash table by the specified key. As the hash table is
2546 collision resistant it also makes it possible to have several
2547 duplicate keys in the hash table. This function may be used to
2548 find all of the keys from the hash.
2550 Added user_context arguments to the SilcHashFunction,
2551 SilcHashCompare and SilcHashDestructor to deliver user specified
2554 Added new fuctions silc_hash_table_find[_all]_ext to do
2555 extended lookup with specified hash and compare functions and
2556 specified user contexts.
2558 Added new function silc_hash_table_add_ext to add the key
2559 with specified hash function and user context.
2561 Added new function silc_hash_table_foreach to traverse all
2562 entrys in the hash table. Added SilcHashForeach callback
2565 Added new function silc_hash_table_del_by_context to delete
2566 the entry only if the context associated with the key matches.
2568 Affected files are lib/silcutil/silchashtable.[ch].
2570 * Removed silc_hash_[server/client/channel]_id and added just
2571 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2572 silc_hash_id_compare to compare two ID's using as the hash table
2573 comparison function. Added also silc_hash_data to hash
2574 binary data and silc_hash_data_compare to compare it.
2576 * Removed silc_idlist_find_client_by_hash as it is not needed
2577 anymore. Affected file silcd/idlist.[ch].
2579 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2580 to use internally the SilcHashTable. The new ID Cache is a lot
2581 faster than the old one. Some of the ID Cache interface was also
2582 rewritten and obsolete and stupid functions were removed.
2584 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Added entry_count field to the SilcHashTable to keep the number
2587 of the entries in the table. Implemented the function
2588 silc_hash_table_rehash. Added new function
2589 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2591 Fixed a minor bug in silc_hash_table_free.
2593 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2594 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2595 into the lib/silcutil/silcutil.[ch].
2597 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Implemented a collision resistant hash table into the
2600 lib/silcutil/silchashtable[ch]. See the header and the source
2601 for the SilcHashTable API.
2603 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Merged dotconf version 1.0.2 into lib/dotconf.
2607 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Do not compile anything in lib/silcsim/* if the SIM support
2610 is not enabled. The tree should now compile without problems
2613 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Compiled the SILC under cygwin. Compiled and tested briefly
2616 without problems. More tests needed. The SIMs didn't compile
2619 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2621 * Fixed possible crash in silc_get_username in the
2622 lib/silcutil/silcutil.c.
2624 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Fixed a va_arg in silc/client_ops.c.
2628 * Oops, RC5 routines were named AES and caused some problems
2629 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2631 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Added new SilcIDIP structure into the lib/silccore/id.h and
2634 replaced the old `ip' fields from all SILC ID's to that type.
2635 This is a step towards IPv6 support.
2637 The silc_id_get_len takes now the ID as an extra argument.
2638 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2639 both IPv4 and IPv6 based ID's.
2641 The affected files are lib/silccore/id.[ch] and other files
2642 around the tree using these routines.
2644 * Removed the ID length arguments in server from various
2645 silc_server_send_notify_* routines -> they are not needed
2648 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Fixed memory leak in silc_encode_pem_file in the file
2651 lib/silcutil/silcutil.c.
2653 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Check minor version as well in the SKE. Affected files are
2656 silcd/protocol.c and lib/silcclient/protocol.c.
2658 * Added --identifier option to the server so that an identifier
2659 can be when creating the public key for the server. Affected
2660 file is silcd/silcd.c.
2662 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2663 lib/silccrypt/silcpkcs.c.
2665 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Register default ciphers and stuff when using -C option with
2668 the server. Affected file sildc/silcd.c.
2670 * Put back the servers public key filename format, it is better
2671 than the new one. For now, the client keys are saved with the
2672 new filename format. The affected file silc/client_ops.c.
2674 * Implemented the Cipher API for the rest of the ciphers that
2675 did not implement it or implemented it the wrong way.
2677 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Register default ciphers and stuff when using the -S option
2680 in the client. Affected file silc/silc.c. Same also when
2681 creating new key pair with -C option.
2683 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Fixed the silc_verify_public_key client operation function to
2686 save the public keys differently. The fingerprint is now
2687 used as filename and not the hostname. This way also the
2688 client keys are saved uniquely and not with hostnames. The
2689 affected file is silc/client_ops.c.
2691 * Trimmed the silc_hash_fingerprint function to remove extra
2692 whitespaces from the end of the fingerprint. The affected
2693 file is lib/silccrypt/silchash.c.
2697 * Added silc_cipher_register_default function to register all
2698 default ciphers. It can be used when configuration files
2699 does not exist and the application does not want any specific
2700 ciphers in any specific order.
2702 The SilcDList is now used as silc_cipher_list dynamically
2703 allocated cipher list. Removed the static list all together
2704 and now all ciphers must be allocated to the dynamic list.
2705 The silc_cipher_alloc routine was changed to check only the
2708 All silc_cipher_* routines that used to return int returns
2711 The affected files lib/silccrypt/silccrypt.[ch].
2713 * The same thing was done to silc_hash_* as for silc_cipher_*
2714 routines. Affected files lib/silccrypt/silchash.[ch].
2716 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2717 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2718 Added also silc_pkcs_[un]register[_default] functions.
2719 Removed the data_context from the PKCS API.
2721 * Added silc_hmac_register_default function to register default
2722 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2723 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2724 to unregister all hmacs at once.
2726 * Register the default ciphers, hash functions, PKCSs and HMACs
2727 if client's configuration file does not exist. The affected
2730 * The client did not load the hash functions from the SIM
2731 modules at all. Added support for this. Affected file is
2732 silc/clientconfig.c.
2734 * When decoding public key with silc_pkcs_public_key_decode, check
2735 the supported algorithm only if PKCS are registered. Affected
2736 file lib/silccrypt/silcpkcs.c. The same was done with the
2737 silc_pkcs_private_key_decode.
2739 * Fixed the SILC List routines to keep the list always in order.
2740 It used to change the list's order when traversing the list but
2741 not it preserves the order. Affected file lib/trq/silclist.h.
2743 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Added the client library to use the SilcSocketConnection's
2746 reference counter (by silc_socket_dup) to prevent the bug that
2747 the socket object may be freed underneath async operation.
2749 * The name resolv library checking fixes in the configure.in.pre.
2752 * Created new version of the protocol drafts for future
2753 development. The -03 drafts are the ones that will be changed
2754 in the trunk now and the -02 will remain as they are.
2756 * Send list of CUMODE notifys to the router when announcing
2757 the channel users to the router. Affected file silcd/server.c.
2758 If the router receiving channel founder CUMODE for a channel
2759 that already has channel founder it will send CUMODE notify
2760 to the sender to remove the channel founder rights from the
2761 announced client. Affected file silcd/packet_receive.c.
2763 * The CUMODE notify may now use Server ID as well as the entity
2764 who changes the mode. Updated protocool specs.
2766 * Updated INSTALL and README files.
2768 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * New web pages in the http://silc.pspt.fi. The pages was
2775 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Implemented the [DenyConnectin] config section in the server.
2778 Added silc_server_config_denied_conn to check whether incoming
2779 connection is denied. Affected file silcd/serverconfig.[ch].
2781 * Do not check the ports when checking the incoming configuration
2782 data if the port is 0, meaning any. Affected file is
2783 silcd/serverconfig.c.
2785 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Fixed buffer overflow in silc_string_compare in the file
2788 lib/silcutil/silcutil.c.
2790 * Fixed double free in silc_server_command_leave in the file
2793 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Fixed the version checking in the server. Affected file is
2798 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Fixed the configuration data fetching when accepting new
2801 connections in the server. Affected file silcd/server.c.
2803 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Added `sender_entry' argument to the function
2806 silc_server_packet_relay_to_channel so that we can check
2807 whether some destination actually belongs to the same route
2808 the sender belongs (ie, we must not resend the packet to the
2809 sender). Affected file silcd/packet_send.[ch].
2811 * Added `servername' field to the SilcClientEntry in the server
2812 to hold the name of the server where client is from. Affected
2813 file is silcd/idlist.h.
2815 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Moved the channel message encrypting in the router betwen
2818 router connections from silc_server_channel_message to the
2819 silc_server_packet_relay_to_channel since we want to check
2820 whether we have anybody channel before encrypting anything.
2821 Affected files silcd/packet_[receive/send].c.
2823 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Fixed the [AdminConnection] server config section to support
2826 multiple entries. Affected file silcd/serverconfig.c.
2828 * Added support into the server to check the validity of the
2829 incoming connection before executing any KE or authentication
2832 * The connection configuration is now saved to the KE and
2833 connection auth protocol contexts and not fetched anymore in
2834 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2836 * The local hosts listenning address and port is also resolved
2837 now when starting the server. We want to have the socket object
2838 to include the real address and port for the listener. Added
2839 new function silc_net_check_local_by_sock into the files
2840 lib/silcutil/silcnet.[ch].
2842 * Fixed a broadcast bug in server -> do not broadcast if we
2845 * Fixed a routing bug. Do not route broadcast packets ever.
2846 Broadcast packets must be processed always and not routed since
2847 they may be destined to some other host than yourself and thus
2848 would get routed without no good reason. Affected file is
2851 * Added function silc_server_config_is_primary_route to check
2852 whether primary router connection has been configured (a router
2853 configuration that we are initiating). If there is not, we
2854 will assume that there is only two routers in the SILC network
2855 and we will use the incoming router connection as our primary
2856 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2858 * Changed the order of the broadcasting. Broadcast _after_ the
2859 packet has been processed not before. Affected file is
2862 * Fixed a [ClientConnection] parsing bug. The port was never
2863 parsed correctly thus resulting to port 0. Affected file
2864 silcd/serverconfig.c.
2866 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2867 argument and did not set the broadcast packet flag. Affected
2868 file silcd/packet_send.c. Fixed same bug in the function
2869 silc_server_send_notify as well.
2871 * If we receive NEW_ID packet for our own ID in the server, ignore
2874 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Removed the nickname from the Private Message Payload.
2879 Updated the code and the protocol specs.
2881 * Updated protocol specs for submitting to the IETF.
2883 * Tweaked the Random Number Generator a bit. Affected file
2884 lib/silccrypt/silcrng.c. Exported a new function
2885 silc_rng_[global]_add_noise which can be used to add more
2888 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Do not parse packets with different timeout when protocol
2891 is active -> may cause problem with rekey. Affected file
2894 * When server receives signoff notify it must not create
2895 new channel key if the client is on any channels since the
2896 sender of the signoff notify will create it.
2898 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Added printing of error messages during SKE protocol from the
2901 failure packet sent by server during SKE. Affected file
2904 * Removed the client's failure_callback handling with timeout
2905 and handle it immediately when received.
2907 * The SKE library returned wrong type in SUCCESS and FAILURE
2908 packets. They must be 32 bit MSB not 16 bit MSB.
2910 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Ok, rewrote the logic of the re-key and now it seems to work.
2913 I tested it on high traffic with frequent re-keys without
2914 problems. Added hmac_receive (and renamed hmac to hmac_send)
2915 in SilcClientConnection in lib/silcclient/client.h and
2916 in SilcIDListData in silcd/idlist.h. Also, removed the
2917 SilcPacketParserContext's cipher and hmac fields as they are
2918 not needed anymore and actually caused some problems when
2919 the ciphers and hmac's changed underneath the packet parser.
2921 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * If re-key protocol is active then process the incoming packets
2924 synchronously since we must assure that icoming packets encrypted
2925 with the old key is processed before the new keys is set to
2926 use. This is true other packets than for REKEY packets.
2927 Affected file silcd/server.c. The same was done to client library
2928 as well, affected file lib/silcclient/client.c.
2930 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Fixed bug in client and server to accept the force send if
2933 the packet is send from silc_[server/client]_packet_process
2934 function. Otherwise the packets are never delivered, oops.
2936 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Disable force sending of packets when REKEY protocol is active.
2939 We must assure that no packet is sent directly when rekey is
2940 performed. All packets must be sent through packet queue.
2941 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2942 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2943 function is silc_[server/client]_packet_send_real to check
2946 * Replaced the SIM paths from example config files to
2947 /usr/local/modules. Also, make install creates now
2948 /usr/local/silc/logs directory to hold all the SILC server
2951 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Made the configure.in.pre work on Solaris. Patch by salo.
2955 * Made all ciphers compatible with non-x86 machines. Defined
2956 CBC mode macros into lib/silccrypt/ciphers_def.h.
2958 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Fixed the make install.
2962 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * When MAC computation fails the silc_packet_decrypt returned 0
2965 even though it was supposed to return -1. Fixed this. The
2966 affected file is lib/silccore/silcpacket.c.
2968 * Do not replace the config files in /etc/silc (in make install)
2969 if they already exist. Affected file ./Makefile.am.
2971 * Do not send re-key packets immediately but through packet queue.
2972 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2974 * Changed silc_net_check_host_by_sock to return FALSE if the
2975 IP/DNS could not be resolved. Though, it returns the IP address
2976 now even if it could not resolve it (but returns also FALSE).
2977 Affected file lib/silcutil/silcnet.[ch].
2979 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added silc_pkcs_decode_identifier to decode the public key's
2982 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2983 Added also silc_pkcs_free_identifier. Added also new context
2984 SilcPublicKeyIdentifier.
2986 * Added -S option to the silc client. It is used to dump the
2987 contents of the specified public key file.
2989 * Changed the PKCS api to return the public key length when
2990 setting the public key.
2992 * Fixed a fatal bug in the public and private key file loading.
2993 Affected file lib/silccrypt/silcpkcs.c.
2995 * Execute the packet parsing for client with zero (0) timeout
2996 if the protocol is active. Affected file silcd/server.c.
2998 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Made the key generation options to the silcd program. Added
3001 -C option, equivalent to client's option.
3003 * Added new [ServerKeys] config section to the server. It
3004 configures the server's public and private key.
3006 * Defined generic Public Key Payload into the protocol
3007 specification to send specific type of public keys and
3010 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3011 public key or certificate.
3013 * Implemented the GETKEY command to the server and to the
3014 client library and on user interface.
3016 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Made preliminary `make install' work.
3020 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Added SilcServerRekey context into silcd/idlist.h.
3024 * Added the PFS support as defined in the specification to the
3025 SKE protocol. Affected files lib/silcske/*.c.
3027 * Added `ske_group' field to the SilcServerRekey context to hold
3028 the number of the SKE group that is used with PFS in re-key.
3029 Affected file silcd/idlist.h.
3031 * Added PFS re-key support to the server. Affected file is
3034 * Added silc_protocol_cancel to cancel execution of the next
3035 state of the protocol. Affected file is
3036 lib/silccore/silcprotocol.[ch].
3038 * Added the re-key support with and without PFS to the client
3039 library. Re-key is performed once in an hour, by default.
3041 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3042 Added silc_client_rekey_callback and silc_client_rekey_final.
3043 Affected files are lib/silcclient/protocol.[ch] and
3044 lib/silcclient/client.[ch].
3046 * Removed the `hmac_key' and `hmac_key_len' fields from the
3047 SilcClientConnection structure; not needed. Affected file is
3048 lib/silcclient/client.h.
3052 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Do not ask whether user wants to use the negotiated private key
3055 for private messages, just use it. Affected file is
3056 silc/local_command.c.
3058 * Added `send_enc_key' and `enc_key_len' fields to the
3059 SilcIDListData structure since they are needed in the re-key
3060 phase. Affected file is silcd/idlist.[ch].
3062 * Implemented the simple re-key protocol into the server.
3063 Affected files silcd/server.c and silcd/protocol.[ch]. The
3064 re-key will be performed once in an hour, by default.
3066 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3067 Added silc_server_rekey, silc_server_rekey_callback and
3068 silc_server_rekey_final.
3070 * Removed Tunneled flag from the protocol. Updated the code
3071 and the specifications.
3073 * Adde `pfs' field to the SilcIDListData to indicate whether
3074 the PFS is to be performed in the re-key. Affected file is
3077 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3080 int64 of at least the xintXX size. If void * is less that 4
3081 bytes uint32 * will be used. Defined bool as boolean.
3083 * Changed _ALL_ unsigned long and unsigned int to uint32,
3084 unsgined short to uint16 in the source tree.
3086 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3087 not handle clients that has entry->data.registered == FALSE.
3088 They are not in the network anymore. Affected file is
3091 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Implemented the sending of the SERVER_SIGNOFF notify in the
3094 server. Affected file is silcd/server.c.
3096 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3097 Added also silc_notify_payload_encode_args into the
3098 lib/silccore/silcnotify.[ch].
3100 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3101 Affected file silcd/packet_receive.c.
3103 * Implemented the SERVER_SIGNOFF notify handling in the client
3104 library. Affected file lib/silcclient/client_notify.c. Also,
3105 implemnted the printing of the SERVER_SIGNOFF info to the
3106 application. Affected file silc/client_ops.c.
3108 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3109 if the deleting was successful. Affected file silcd/idlist.[ch].
3111 * Added support for public key authentication in the connection
3112 authentication protocol in the client library. Affected file
3113 lib/silcclient/protocol.c.
3115 * Changed the server's silc_idlist_get_clients_by_* interface
3116 to support already allocated array so that new entries may be
3117 added to pre-allocated array. Affected file silcd/idlist.[ch].
3118 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3119 and command replies.
3121 * All command reply functions in the server now calls the
3122 pending command callback even if error occured. This way the
3123 error will be delivered to the client as well. Affected files
3124 silcd/command.c and silcd/command_reply.c.
3126 * Fixed INFO command to return local server's info if no server
3127 was provided. Affected file lib/silcclient/command.c.
3129 * Removed RESTART command for good. Updated the code and the
3132 * Rewrote parts of the task system. It is a bit simpler now.
3133 Removed unsued task priorities. The affected files are
3134 lib/silcutil/silctask.[ch].
3136 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Moved the USERS printing from the library to the application.
3139 Affected files lib/silcclient/command.c and silc/client_ops.c.
3141 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Added channel key re-key support. The re-key is perfomed
3146 only by the router and is done once in an hour. Added `rekey'
3147 field to the SilcChannelEntry in the server. Affected files
3148 silcd/server.c and silcd/idlist.h.
3150 * Added silc_task_unregister_by_context into the file
3151 lib/silcutil/silctask.[ch].
3153 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Added SILC_UMODE_GONE mode to indicate when the client is not
3156 present in the SILC network. Added also support to the local
3157 command AWAY that will set this mode. Added support of showing
3158 "xxx is gone" in WHOIS command. The USERS command shows the
3159 gone status as well.
3161 * Fixed setting server and router operator privileges in the
3162 server's UMODE command. Affected file silcd/command.c.
3164 * Merged the SKE KE1 and KE2 payloads into one payload. The
3165 new KE payload is equivalent to the old KE2 payload.
3167 Cleaned up the SKE Start Payload parsing. It now uses the
3168 simple buffer unformatting to do the parsing. A lot faster
3171 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3172 to the SKE that is used to indicate whether both of the SKE
3173 parties should perform authentication. By default only the
3174 responder performs authentication. By setting this flag also
3175 the initiator must do authentication. By default it is unset
3176 since in normal SKE case, client to server connection, only
3177 the responder should do authentication. When doing SKE between
3178 two clients both should perform authentication. Updated the
3179 code and the protocol specs.
3181 * A little fix to IDENTIFY command in the server. Search the
3182 client first by hash not nickname. Affected file is
3185 * Fixed the silc_client_close_connection to support closing
3186 the client to client connections wihtout deleting too much
3187 data. Affected file lib/silcclient/client.c.
3189 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3190 are received if protocol used to be active but is not anymore
3191 the application would crash due to NULL pointer dereference.
3192 Affected files silcd/server.c and lib/silcclient/client.c.
3194 * Added `hash' field to the SilcClientConnection to include
3195 the hash function negotiated in the SKE protocol.
3197 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3198 to set the channel founder authentication data. A client can
3199 claim the founder rights later by providing the authentication
3200 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3201 This way the channel founder can regain the channel founder
3202 privileges even it is left the channel. This works only on
3203 local server and the client must be connected to the same
3204 server to be able to regain the founder rights. Updated the
3205 protocol specs accordingly.
3207 Added support to the CMODE command in the client to set the
3208 founder auth data. Read the README to see how to set it.
3210 Added support to the CUMODE command to claim the founder
3211 rights. Read the README to see how to do it.
3213 Added support for the founder authentication to the Channel
3214 Entry in the server. Affected file silcd/idlist.h.
3216 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3217 server's CMODE command. Affected file silcd/command.c.
3219 * Added the following new functions into lib/silccore/silcauth.[ch]:
3220 silc_auth_get_method and silc_auth_get_data.
3222 * The server now saves the remote hosts public key to the
3223 SilcIDListData pointer. Affected file silcd/protocol.c.
3225 * The normal server now does not remove the channel entry from
3226 the cache if the founder authentication data is set. It used
3227 to remove it if the founder was the last one on the channel on
3228 the server and left the channel. The auth data is saved and
3229 if the channel is re-joined later the old entry is used with
3230 the old auth data. Affected files silcd/command_reply.c and
3233 * Removed the `pkcs' field from the SilcIDListData structure
3234 in the server; it is not used. Affected file silcd/idlist.h.
3236 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Fixed packet processing on slow links. Partial packets were
3239 never re-processed because the incoming data buffer was cleared
3240 by the application. Application must not directly clear the
3241 sock->inbuf, the packet processing routines handle it. Fixed
3242 this in client library and in server.
3244 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Fixed the WHOIS and IDENTIFY send reply function to really
3247 check whether to send list or just one entry. Affected file
3250 * Cleaned up the LEAVE command's channel key distribution. The
3251 affected file silcd/command.c.
3253 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3254 can enforce the channel mode as well. In that case the ID
3255 includes the ID of the server. The code now enforces the
3256 mode change if the router have different mode than the server.
3258 * The notify client operation with CMODE_CHANGE notify can now
3259 return NULL client_entry pointer if the CMODE was not changed
3260 by client. Application must check for this.
3262 * Added <Server ID> argument to INFO command to support server
3263 info fetching by Server ID.
3265 * Added silc_server_announce_get_channel_users to get assembled
3266 packets of channel users of the specified channel. Affected
3267 file silcd/server.[ch].
3269 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3270 was freed underneath the ID Cache.
3272 * Re-announce clients when the server received CHANNEL_CHANGE
3273 notify from the router. Affected file silcd/packet_send.c.
3275 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3278 crashed since it did not handle the fact that there is no cipher
3279 called "3" and didn't check the error condition. Now fixed.
3281 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3282 flag. It can be used to send message requests.
3284 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Implemented the RESTART command in the client.
3288 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3289 notice type messages. Added notice printing to the user
3292 * The channel keys are not re-generated if the channel's mode
3293 is PRIVKEY, ie private key on the channel exists. Affected
3294 files silcd/server.c and silcd/command.c.
3296 * Fixed a little bug in channel message delivery when channel
3297 private keys are set in the server. Affected file is
3298 silcd/packet_send.c.
3300 * Changed the setting on channel->on_channel = TRUE from the
3301 silc_client_save_channel_key to the JOIN command reply. The
3302 key payload is not received if the private channel key is set.
3303 Affected file lib/silcclient/command_reply.c and the
3304 lib/silcclient/client_channel.c.
3306 * When the CMODE_CHANGE notify is sent and the channel private
3307 key mode is removed the channel key must be re-generated in
3308 other cells as well. Added this support for the router in the
3309 silcd/packet_receive.c.
3311 * Added new local command NOTICE to send notice message on
3312 channel. Affected file silc/local_command.[ch].
3314 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Added new local command ME to the client. It is used to send
3317 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3318 some action. Affected file silc/local_command.[ch].
3320 * Changed channel_message and private_message client operations
3321 to deliver the message flags to the application. Added also
3322 the `flags' arguments to the silc_client_send_channel_message
3323 and silc_client_send_private_message functions. Affected file
3326 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Redefined the Private Message Payload to support private message
3329 keys and to support the new private message flags. Updated
3330 the protocol specs. Flags makes it possible to have for example
3331 CTCP style messages.
3333 * Added new type SilcPrivateMessagePayload and defined an API
3334 for it in the lib/silcclient/silcprivate.[ch].
3336 * Tested private message private keys successfully. Tested the
3337 private message key set, unset and list commands with the new
3340 * Redefined the Channel Message Payload to include the channel
3341 message flags (equal with private message flags) to support
3342 for example CTCP style messages.
3344 * Defined some of the message (for channel and private message)
3345 flags. Updated the protocol specs and added the flags to the
3346 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3348 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Added SilcKeyAgreementStatus type to the key agreement routines
3351 to indicate the current status and error if one occured.
3352 The status types are defined in the lib/silcclient/silcapi.h.
3354 * Added new local command KEY that is used to set and unset private
3355 keys for channels, set and unset private keys for private messages
3356 with remote clients and to send key agreement requests and
3357 negotiate the key agreement protocol with remote client. The
3358 key agreement is supported only to negotiate private message keys,
3359 it currently cannot be used to negotiate private keys for channels,
3360 as it is not convenient for that purpose.
3362 * Fixed a minor pending callback setting bug in the function
3363 silc_client_get_client_by_id_resolve, now the function works.
3364 Affected file lib/silcclient/idlist.c.
3366 * Added function silc_net_get_local_port to get local bound
3367 port by socket. Added to lib/silcutil/silcnet.[ch].
3369 * Added `sockets' and `sockets_count' fields to the SilcClient
3370 object. They hold the sockets of the listenning sockets in
3371 the client. Listenning sockets may be for example the key
3372 agreement server. Affected file lib/silcclient/client.[ch].
3373 Added functions the silc_client_add_socket and the
3374 silc_client_del_socket. They are exported to the application
3377 * Added ~./silc/clientkeys to support other client's public keys.
3379 * Renamed verify_server_key client operation to verify_public_key
3380 and added one argument to indicate the type of the connection
3381 (server, client etc.).
3383 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added silc_server_connection_auth_request to handle the
3386 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3387 silcd/packet_receive.[ch].
3389 * Added silc_server_send_connection_auth_request into the
3390 silcd/packet_send.c to send the connection auth request packet.
3392 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3395 * Fixed the public key authentication in responder side in the
3396 server. The `auth_data' pointer includes the SilcPublicKey
3397 not the path to the public key. Affected file silcd/protocol.c.
3399 * Implemented the public key authentication in the initiator side
3400 in the server. Affected file silcd/protocol.c.
3402 * Removed the [RedirectClient] config section from the server
3403 configuration. Is not needed and I don't want to implement it.
3405 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Cleaned up the CMODE command in the server. It now works
3408 correctly and supports all the modes defined in the protocol.
3409 Affected file is silcd/command.c.
3411 * Added `hmac_name' field to the SilcChannelEntry in the server
3412 to hold the default HMAC of the channel. It can be set when
3413 creating the channel (with JOIN command). Affected files
3416 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3417 type to indicate the change of the current cipher and hmac
3418 on the channel. Client can safely ignore the <cipher> argument
3419 (if it chooses to do so) since the CHANNEL_KEY packet will
3420 force the channel key change anyway. The <hmac> argument is
3421 important since the client is responsible of setting the new
3422 HMAC and the hmac key into use.
3424 * Fixed the CMODE command in the client library as well.
3426 * Tested CMODE command in router environment successfully.
3428 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Show the version of the remote client (or server) when connecting
3431 to the server. It is logged to the log file. Affected file
3432 is silcd/protocol.c.
3434 * Fixed the KILLED notify handling in the client library. The
3435 client must be removed from all channels when receiving the
3438 Also, do not remove the client entry when giving the KILL
3439 command but when the KILLED notify is received.
3441 * Removed silc_idlist_find_client_by_nickname from the server.
3442 Not needed anymore. Affected files silcd/idlist.[ch].
3444 * Implemented the CHANNEL_CHANGE notify type handling to the
3445 server. Affected file silcd/server.c.
3449 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Added silc_server_send_notify_invite to send the INVITE
3452 notify between routers.
3454 * Implemented the INVITE command correctly to the server.
3456 * Implemented the INVITE notify type handling in the server.
3458 * Implemented the INVITE command to the client library and on the
3461 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Added function silc_server_get_client_resolve to find the
3464 client entry by ID from all ID lists and then resolve it
3465 (using WHOIS) if it cannot be found. Affected file is
3468 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Implemented the BAN command to the client library.
3472 * The JOIN command in the server now checks the invite list
3475 * Changed the silc_command_reply_payload_encode_va and the
3476 silc_command_payload_encode_va to support that if argument is
3477 NULL it ignores and checks the next argument. Affected file
3478 lib/silccore/silccommand.c.
3480 * Added silc_server_send_notify_ban to send the BAN notify
3481 type between routers.
3483 * Chaned the silc_notify_payload_encode to support that if
3484 argument is NULL it ignores and checks the next argument.
3485 Affected file lib/silccore/silcnotify.c.
3487 * Tested ban lists in router environment successfully.
3489 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Implemented BAN command to the server, in silcd/command.[ch].
3493 * Removed the BAN and INVITE_LIST modes from the CMODE command
3496 * Added function silc_string_match to regex match two strings.
3497 Affected files lib/silcutil/silcutil.[ch].
3499 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Redefined parts of the SilcChannelEntry in the server to support
3502 the new ban and invite lists.
3504 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Redefined the INVITE command. The same command can be used to
3507 invite individuals to the channel but also to manage the invite
3508 list of the channel (to add to and remove from the invite list).
3509 Updated the protocol specs.
3511 * Added new command SILC_COMMAND_BAN that can be used to manage
3512 the ban list of the channel. Updated the protocol specs.
3514 * Removed the channel modes: the SILC_CMODE_BAN and the
3515 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3516 in the CMODE command. The equivalent features are now available
3517 using INVITE and BAN commands. Updated the protocol specs.
3519 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3520 in the network about change in the current ban list. The notify
3521 type is not used by the client.
3523 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3524 support the invite lists.
3526 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Added new function silc_string_regexify that converts string
3529 including wildcard characters into regex string that can
3530 be used by the GNU regex library. Added into the file
3531 lib/silcutil/silcutil.[ch].
3533 Added silc_string_regex_combine to combine to regex strings
3534 into one so that they can be used as one regex string by
3535 the GNU regex library. Added into the file
3536 lib/silcutil/silcutil.[ch].
3538 Added silc_string_regex_match to match two strings. It returns
3539 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3541 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Imported GNU regex to the soruce tree into lib/contrib.
3544 Fixed some compiler warning from the regex.c.
3546 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3548 * Fixed MOTD command in the server to work in router environment.
3550 * Fixed the MOTD command in the client library to support
3551 the server argument in the command.
3553 * Added `nickname_len' argument to the silc_idlist_add_client
3554 in the server, as the `nickname' argument may be binary data
3557 * Added silc_idlist_get_channels to return all channels from
3560 * Implemented LIST command to the server. Affected file is
3563 * Implemented the LIST command to the client library and on the
3566 * Added [<user count>] argument to the LIST command reply.
3567 With private channels the user count is not shown.
3569 * Updated TODO and README.
3571 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * The client entry's data.registered must be TRUE even with
3574 global client entry on global client list. The data.registered
3575 is used to check whether the client is anymore in the network,
3576 for example with WHOWAS command so it must be valid.
3578 * Fixed the WHOWAS command in the server. It now actually works
3579 in router environment. Added function into silcd/command_reply.c
3580 silc_server_command_reply_whowas_save.
3582 * Added silc_idlist_purge function to the silcd/idlist.c
3583 to periodically purge the ID Cache.
3585 * Fixed INFO command in the server. It works now in router
3586 environment. Added <server name> argument to the INFO command
3587 reply. Updated the protocol specs.
3589 * Fixed minor bug in silc_idcache_purge to not purge if the
3590 expire value is zero.
3592 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3593 they were buggy because of the WHOWAS information.
3595 * Fixed local command MSG to handle the async resolving of
3596 the remote client properly. It used to fail the first MSG.
3597 Affected file silc/local_command.c.
3599 * Added `data_len' field to SilcIDCache context.
3601 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Update TODO. Todo in commands in the server.
3605 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3608 used by routers as broadcast packet to inform other routers
3609 about the changed user mode.
3611 Implemented the notify handling in the server. Affected file is
3612 silcd/packet_receive.c. Added the function
3613 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3615 * Added new generic Channel Payload and deprecated the New Channel
3616 Payload. The New Channel Payload is now the generic Channel
3619 * Added new argument `mode' to the silc_server_send_new_channel
3620 as it is required in the Channel Payload now.
3622 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3623 and created a new and real SilChannelPayload to represent the
3624 new generic Channel Payload. Implemented the encode/decode
3625 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3627 * Added silc_server_get_client_channel_list to return the list
3628 of channels the client has joined for WHOIS command reply.
3629 Affected file silcd/server.[ch].
3631 * Implemented the channel list sending in the WHOIS command reply
3632 in server and in the client.
3634 Implemented the channel list displaying on the user interface
3635 as well. Affected file silc/client_ops.c.
3637 * Added silc_channel_payload_parse_list to parse list of Channel
3638 Payloads. It returns SilcDList list of SilcChannelPayloads.
3639 Client for example can use this function to parse the list of
3640 channels it receives in the WHOIS command reply. The caller
3641 must free the list by calling silc_channel_payload_list_free.
3642 Affected files lib/silccore/silcchannel.[ch].
3644 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Added one new argument <user mode> to the WHOIS command reply
3647 to return the mode of the user in SILC. Updated the protocol
3650 Implemented it to the server and client.
3652 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Fixed the mode printing on the user interface on joining.
3655 Affected file silc/client_ops.c.
3657 * Implemented the UMODE command and user modes in general to the
3658 client library and to the user interface.
3660 * Implemented the UMODE command to the server.
3662 * The server now sends UNKNOWN_COMMAND error status if client sends
3663 unknown command. Affected file silcd/command.c.
3665 * All server commands now handle the command identifier the right
3666 way when sending the command reply to the client. The client can
3667 use to identify the command replies with the identifier.
3669 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * Added silc_server_get_client_route to resolve the route to
3672 the client indicated by the client ID. Affected file is
3675 * Added silc_server_relay_packet as general function to relay
3676 packet to arbitrary destination. This deprecates functions
3677 like _send_private_message_key, _relay_notify etc. Affected
3678 file is silcd/packet_send.[ch].
3680 Removed silc_server_send_key_agreement,
3681 silc_server_send_private_message_key and
3682 silc_server_packet_relay_notify functions from the file
3683 silcd/packet_send.[ch].
3687 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3688 server. Affected file silcd/packet_receive.[ch].
3690 * Implemented the KILL command to the client. Implemented the
3691 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3692 Affected files lib/silcclient/command[_reply].c and
3693 lib/silcclient/client_notify.c. Implemented the KILL notify
3694 printing in the user inteface.
3696 * Fixed a lot silc_parse_nick memory leaks from the client
3697 library in the file lib/silcclient/command.c.
3699 * Changed the silc_server_send_notify_on_channels's `sender'
3700 argument from SilcSocketConnection to SilcClientEntry to
3701 check the sender as entry and not as connection object and not
3702 to send to the client provided as argument. The affected file
3703 is silcd/packet_send.[ch].
3705 * The notify packets that are destined directly to the client used
3706 to not to be processed by the server. Now changed that and the
3707 server processes all notify packets. After relaying the packet
3708 to the client the notify packet is processed in the server.
3710 * The silc_server_free_client_data now checks whether there is
3711 pending outgoing traffic for the client and purges the data to
3712 the network before removing the client entry.
3714 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3717 an client is killed from the SILC Network. Updated the protocol
3720 Added new function silc_server_send_notify_killed to the
3721 silcd/packet_send.[ch].
3723 * Added function silc_server_packet_relay_notify to relay notify
3724 packets that are destined directly to a client. In this case
3725 the server does not process the notify packets but merely relays
3726 it to the client. Affected file silcd/packet_send.[ch].
3728 Added also silc_server_packet_process_relay_notify to check
3729 whereto relay the notify. Affected file is
3730 silcd/packet_receive.[ch].
3732 * Implemented the KILL command to the server.
3736 * Added the backup schema desgined last fall to the protocol
3737 specs for everyone to see. The specification is in the
3738 *-spec-xx.txt draft and the packet type definitions for the
3739 backup routers is in *-pp-xx.txt draft. Thusly, added also
3740 new packet type SILC_PACKET_CELL_ROUTERS.
3742 * A big security problem in the implementation discovered. The
3743 signoff of an client did not cause new channel key generation
3744 which it of course should've done. The channel keys must be
3745 always re-generated when client leaves (or signoffs) the channel.
3746 The silc_server_remove_from_channels funtion now handles
3747 the channel key re-generation.
3749 * Added `sender' argument to the silc_server_send_notify_on_channels
3750 to not to send the client provided as argument. Affected file
3751 silcd/packet_send.[ch].
3753 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Implemented OPER and SILCOPER commands into the server and
3758 * Added silc_auth_verify and silc_auth_verify_data to verify
3759 the authentication directly from the authentication payload.
3760 It supports verifying both passphrase and public key based
3761 authentication. Affected file lib/silccore/silcauth.[ch].
3763 * Added `hash' field to the SilcIDListData structure. It is the
3764 hash negotiated in the SKE protocol. Affected file is
3767 * Slight redesigning of the SilcAuthPayload handling routines.
3768 Do not send SilcPKCS but SilcPublicKey as argument.
3770 * Implemented the public key authentication support to the
3771 serverconfig. The public key is loaded from the provided path
3772 and saved as authentication data to void * pointer. Thus,
3773 changed the unsigned char *auth_data to void *auth_data;
3775 * Fixed SHUTDOWN command to send the reply before the server
3776 is shutdown. :) Affected file silcd/command.c.
3778 * Fixed fatal bug in CONNECT command. The hostname was invalid
3779 memory and server crashed. Affected file silcd/command.c.
3781 * Fixed fatal bug in CLOSE command. The server_entry became
3782 invalid but was referenced later in the command. Affected file
3785 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Fixed fatal bug in failure packet handling. Server ignored
3788 the failure and thus crashed when it came.
3792 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3795 that the command may be executed only once in (about) 2 seconds.
3796 The old SILC_CF_LAG flag is same but allows command bursts up
3797 to five before limiting.
3799 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3800 server code. Various commands now includes the CF_LAG_STRICT
3801 flag to disallow any kind of miss-use of the command.
3803 * Fixed the silc_buffer_unformat to not to allocate any data
3804 if the length of the data is zero. It used to allocate the
3805 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3807 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Changed the format of AdminConnection configuration section
3810 in the server. Added username of the admin to the format.
3811 Affected files silcd/serverconfig.[ch].
3813 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3814 to return admin configuration data by host, username and/or
3817 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Implemented WHOWAS command to the server. Added the functions:
3821 silc_server_command_whowas_parse,
3822 silc_server_command_whowas_send_reply,
3823 silc_server_command_whowas_from_client and
3824 silc_server_command_whowas_from_server
3826 * Added <Client ID> argument to the WHOWAS command reply. Updated
3827 the protocol specs accordingly.
3829 * Implemented WHOWAS command and command_reply to the client
3832 Implemented the WHOWAS printing on the user interface.
3834 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added new argument to the WHOWAS command reply, the real name.
3837 It is an optional argument. Updated the protocol specs.
3839 * Added SilcIDCacheDestructor callback that is registered when
3840 the SilcIDCache is allocated. The callback is called when
3841 an cache entry in the ID Cache expires, or is purged from the
3842 cache. Added into lib/silccore/idcache.[ch].
3844 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3845 to destruct the client entries when the cache entry expires.
3846 Other ID Cache's in server and in the client library ignores
3849 * If the ID Cache entry's `expire' field is zero then the entry
3850 never expires. Added boolean `expire' argument to the
3851 silc_idcache_add function in the lib/silccore/idcache.[ch].
3852 If it is TRUE the default expiry value is used.
3854 * Added silc_server_free_client_data_timeout that is registered
3855 when client disconnects. By default for 5 minutes we preserve
3856 the client entry for history - for WHOWAS command.
3858 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added support to the server to enforce that commands are not
3861 executed more than once in 2 seconds. If server receives
3862 commands from client more frequently, timeout is registered
3863 to process the commands. Affected file silcd/command.c.
3864 Added new function silc_server_command_process_timeout.
3866 * Changed NICK_NOTIFY handling in client library to check that
3867 if the client's nickname was changed, so there is no need to
3868 resolve anything from the server.
3870 * Removed error printing from the WHOIS and IDENTIFY commands.
3871 If error occurs then it is ignored silently in the client library.
3872 The application, however, may map the received error to
3873 human readable error string. The application currently maps
3874 the NO_SUCH_NICKNAME error to string.
3876 * Made the command status message public to the application. Moved
3877 them from lib/silcclient/command_reply.c to
3878 lib/silcclient/command_reply.h. The application can map the
3879 received command status to the string with the
3880 silc_client_command_status_message function.
3882 * Added check to the server to check that client's ID is same
3883 as the Source ID in the packet the client sent. They must
3886 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Added dist-bzip hook to the Makefile.am to make bzip2
3889 compressed distributions.
3891 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Server now enforces the maximum length for the nickname and
3894 the channel as protocol specification dictates. 128 bytes for
3895 nickname and 256 bytes for channel name.
3897 * Moved the WHOIS printing to the application. The client libary
3898 does not print out the WHOIS information anymore, the application
3899 must do it. Renamed silc_client_command_reply_whois_print to
3900 the silc_client_command_reply_whois_save.
3902 The client's idle time is also sent to the application now, and
3903 the idle is shown on screen.
3905 * Added silc_client_command_reply_identify_save to save the
3906 received IDENTIFY entries.
3908 * Do not check for channel private keys in message sending and
3909 reception if the channel does not have the PRIVKEY mode set.
3910 Affected file lib/silclient/client_channel.c.
3912 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3915 just surfaced after chaning the JOIN procedure.
3917 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Added silc_client_get_clients_by_list to get client entries
3920 from Client ID list, that is returned for example by JOIN
3921 and USERS command replies. The application should use this
3922 function for example when JOIN command reply is received to
3923 resolve the clients already on the channel (library does not
3924 do that anymore as USERS command reply is not used in the JOIN
3925 procedure anymore). Affected files lib/silcclient/silcapi.h and
3926 lib/silcclient/idlist.c.
3928 * JOIN command reply and USERS command reply returns now SilcBuffer
3929 pointers instead of unsigned char pointers when returning
3930 the client list and mode list.
3932 * Added <Client ID> argument to the JOIN command reply, mainly
3933 for the server to identify for which client the command was
3934 originally sent. Updated protocol specs accordingly.
3936 * Added SilcDlist private_key pointer to the SilcChannelEntry
3937 in the client to support the channel private keys. Affected
3938 file is lib/silcclient/idlist.h.
3940 * Added SilcChannelPrivateKey argument to the function
3941 silc_client_send_channel_message so that application can choose
3942 to use specific private ke if it wants to. If it is not provided,
3943 the normal channel key is used, unless private keys are set.
3944 In this case the first (key that was added first) is used
3945 as the encryption key.
3947 * Implemented the support for channel private key handling.
3948 Implemented the following functions:
3950 silc_client_add_channel_private_key,
3951 silc_client_del_channel_private_keys,
3952 silc_client_del_channel_private_key,
3953 silc_client_list_channel_private_keys and
3954 silc_client_free_channel_private_keys
3956 Affected file lib/silcclient/client_channel.c.
3958 * Added the support for the private keys in the channel message
3959 sending and encryption and in the message reception and
3960 decryption. Affected funtions are
3961 silc_client_send_channel_message and silc_client_channel_message.
3963 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Added SKE's key verify callback to the client library's
3966 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3968 * Removed the statement that server (or router) must send USERS
3969 command reply when joining to the channel so that the client
3970 knows who are on the channel. Instead, the client list and
3971 client's mode list is now sent in the JOIN command reply to the
3972 client who joined channel. This is better solution.
3974 * Added function silc_server_get_users_on_channel and function
3975 silc_server_save_users_on_channel to the silcd/server.[ch].
3977 * Removed function silc_server_command_send_users from the
3980 * Do not show topic on the client library anymore. The topic is
3981 sent in the command reply notify to the application and the
3982 application must show the topic now.
3984 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Added client searching by nickname hash into the IDENTIFY and
3987 WHOIS commands in the server as they were clearly missing from
3988 them. Affected file is silcd/command.c.
3990 * Fixed a bug in private message receiving in the client library.
3991 The remote ID was freed and it wasn't supposed, now it is
3994 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Minor fix to the channel payload; allocate the data area, as it
3997 needs to be of specific length.
3999 * If the key agreement port is zero then the operating
4000 system will define the bound port. Affected files are
4001 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4003 * Added new function silc_channel_payload_decrypt into the file
4004 lib/silccore/silcchannel.[ch].
4006 * Moved the channel message etc, check from silc_packet_decrypt
4007 to applications. The library calls now a generic
4008 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4009 when the packet is either normal or special. This was done to
4010 allow more wide range of checking that was not allowed when
4011 the code was in library. Now applications can do virtually any
4012 checks to the packet and return to the library the decision how
4013 the packet should be processed. Affected files are
4014 lib/silccore/silcpacket.[ch].
4016 Added silc_server_packet_decrypt_check to the server and
4017 silc_client_packet_decrypt_check to the client library.
4019 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4020 to send with specified source and destination information.
4022 * Channel message delivery between routers was broken after the
4023 channel key distribution was fixed earlier. The channel key
4024 was used be to distributed to other routers as well which is not
4025 allowed by the protocol. Now this is fixed and channel keys
4026 really are cell specific and the channel message delivery between
4027 routers comply with the protocol specification.
4029 * Fixed various commands in server to check also the global list
4030 for the channel entry and not just the local list. The affected
4031 file silcd/command.c.
4033 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added assert()s to buffer formatting and unformatting routines
4036 to assert (if --enable-debug) when error occurs. Affected
4037 file: lib/silcutil/silcbuffmt.c.
4039 * Changed to auto-reconnect to check whether the remote host is
4040 router and register the re-connect timeout if it is. It used
4041 to check that whether we are normal server, but router must do
4042 auto-reconnect with another router as well. Affected file
4045 * Removed the [<key len>] option from CMODE command as the cipher
4046 name decides the key length, nowadays. See the defined ciphers
4047 from the protocol specification.
4049 * Added [<hmac>] option to the CMODE command to define the HMAC
4050 for the channel. Added SILC_CMODE_HMAC channel mode.
4052 * Added [<hmac>] option for the JOIN command so that user can
4053 select which HMAC is used to compute the MACs of the channel
4056 * Added Hmac field to the Channel Message Payload. The integrity
4057 of plaintext channel messages are now protected by computing
4058 MAC of the message and attaching the MAC to the payload. The
4059 MAC is encrypted. Now, it is clear that this causes some
4060 overhead to the size of the packet but rationale for this is that
4061 now the receiver can verify whether the channel message decrypted
4062 correctly and also when private keys are set for the channel the
4063 receiver can decrypt the packet with several keys and check from
4064 the MAC which key decrypted the message correctly.
4066 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4067 lib/silccrypt/silccipher.[ch].
4069 * Added silc_hash_len to return the digest length into the
4070 lib/silcrypt/silchash.[ch].
4072 * Rewrote parts of Silc Channel Payload interface in the
4073 lib/silccore/silcchannel.[ch]. The encode function now also
4074 encrypts the packet and parse function decrypts it.
4076 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Fixed a minor formatting bug in the SKE's key material processing.
4079 It actually might have processed the keys wrong way resulting
4082 * Redefined the mandatory HMAC algorithms and added new algorithms.
4083 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4084 and hmac-md5 truncated to 96 bits. The mandatory is now
4085 hmac-sha1-96. Rest are optional (including the one that used
4086 to be mandatory). Rationale for this is that the truncated HMAC
4087 length is sufficient from security point of view and can actually
4088 make the attack against the HMAC harder. Also, the truncated
4089 HMAC causes less overhead to the packets. See the RFC2104 for
4092 * Added new [hmac] configuration section. The SKE used to use
4093 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4094 is of course wrong. The official names that must be proposed in
4095 the SKE are the ones defined in the protocol specification
4096 (hmac-sha1-96 for example). The user can configure any hmac
4097 using any hash function configured in the [hash] section. At
4098 least, the mandatory must be configured.
4100 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4102 * Added HMAC list to the SKE proposal list. It has now both
4103 hash algorithm list and HMAC list. This makes the protocol
4104 incompatible with previous versions. The SKE now seems to work
4105 the way it is supposed to work, for the first time actually.
4107 * Defined plain Hash algorithms to the protocol specification.
4110 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * Implemented support for key agreement packets into the server.
4113 Added functions silc_server_key_agreement and
4114 silc_server_send_key_agreement. Other than these functions,
4115 server has nothing to do with this packet.
4117 * Added support for private message key packets into the server.
4118 Added functions silc_server_private_message_key and
4119 silc_server_send_private_message_key.
4123 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4124 called in the protocol's final callback instead in the END
4125 protocol state. This makes a little more sense and in the same
4126 time in client we can use the same protocol routines for normal
4127 key exchange and to key agreement packet handling as well.
4129 * Added to both client's and server's KE protocol context the
4130 SilcSKEKeyMaterial pointer to save the key material. We will
4131 bring the key material to the protocol's final callback by doing
4132 this. The final callback must free the key material.
4134 * Added SKE's packet_send callback into client's KE protocol
4135 context so that the caller can choose what packet sending function
4136 is used. This way we can use different packet sending when
4137 doing normal SKE when doing key agreement packet handling (in
4138 the key agreement packet handling we do not want to encrypt
4141 * Implemented the responder side of the key agreement routines
4142 in the client. The client can now bind to specified port and
4143 accept incoming key negotiation. The key material is passed
4144 to the application after the protocol is over.
4146 * Implemented the processing of incoming Key Agreement packet
4147 in the client. Added function silc_client_key_agreement to
4150 * Implemented the intiator side of the key agreement routines
4151 in the client. The client can now initiate key agreement with
4152 another remote client. The key material is passed to the
4153 application after the protocol is over.
4155 * Created client_keyagr.c to include all the key agreement
4158 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4159 SILC_TASK_CALLBACK except that it is not static.
4161 * Created client_notify.c and moved the Notify packet handling
4162 from the client.[ch] into that file.
4164 * Created client_prvmsg.c and moved all private message and
4165 private message key routines from the client.[ch] into that file.
4167 * Create client_channel.c and moved all channel message and
4168 channel private key routines from the client.[ch] into that file.
4170 * Changed silc_client_get_client_by_id_resolve to resolve with
4171 WHOIS command instead of IDENTIFY command, in the file
4172 lib/silclient/idlist.c.
4174 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Implemented the SKE's responder side to the Client library.
4178 * When FAILURE is received to the protocol do not trust it
4179 blindly. Register a timeout to wait whether the remote closes
4180 the connection as it should do it, only after that process the
4181 actual failure. This was changed to both client and server.
4183 * Added client_internal.h to include some of the structures
4184 there instead of client.h in lib/silcclient/.
4186 * Added function silc_task_unregister_by_callback to unregister
4187 timeouts by the callback function.
4189 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Some "Incomplete WHOIS info" errors has been appearing on the
4192 log files. Took away the entry->userinfo check from WHOIS
4193 reply sending. The entry->userinfo is now " " if client did not
4194 provide one. I thought this was fixed earlier but something
4195 is wrong still. Let's see if the error still appears.
4197 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Fixed a minor bug in the login when the channel key is
4200 re-generated in the server. It used to generate the key in
4201 wrong order and thus caused problems in the channel traffic.
4203 * Fixed a minor bug in channel key distsribution after
4204 KICK command. The key was not sent to the router even though
4207 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Added silc_ske_process_key_material_data as generic routine
4210 to process any key material as the SILC protocol dictates. The
4211 function is used by the actual SKE library but can be used by
4212 applications as well. This relates to the private message keys
4213 and the channel private keys since they must be processed the
4214 same way the normal SILC session keys. The protocol dictates
4215 this. Affected files: lib/silcske/silcske.[ch].
4217 Added also silc_ske_free_key_material to free the
4218 SilcSKEKeyMaterial structure.
4220 * Defined silc_cipher_set_key function to set the key for
4221 cipher without using the object's method function. The affected
4222 files: lib/silccrypt/silccipher.[ch].
4224 * Implemented silc silc_client_add_private_message_key,
4225 silc_client_add_private_message_key_ske,
4226 silc_client_del_private_message_key,
4227 silc_client_list_private_message_keys and
4228 silc_client_free_private_message_keys functions in the
4231 Added functions silc_client_send_private_message_key to send
4232 the Private Message Key payload and silc_client_private_message_key
4233 to handle incoming Private Message Key payload.
4235 * Added Cipher field to the Private Message Key payload to set
4236 the cipher to be used. If ignored, the default cipher defined
4237 in the SILC protocol (aes-256-cbc) is used.
4239 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Removed lib/silcclient/ops.h file.
4243 Redefined parts of the SILC Client Library API. Created new
4244 file silcapi.h that deprecates the ops.h file and defines the
4245 published Client Library API. Defined also private message key
4246 API and channel private key API into the file.
4248 This is the file that the application must include from the
4249 SILC Client Library. Other files need not be included by
4250 the application anymore.
4252 * Added new key_agreement client operation callback and also
4253 defined the Key Agreement library API for the application.
4255 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4258 is used by clients to request key negotiation between another
4259 client in the SILC network. If the negotiation is started it
4260 is performed using the SKE protocol. The result of the
4261 negotiation, the secret key material, can be used for example
4262 as private message key.
4264 Implemented the Key Agreement payload into the files
4265 lib/silccore/silauth.[ch].
4267 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Redefined ciphers for the SILC protocol. Added some new ciphers
4270 and defined the key lengths for the algorithms. Changed the
4271 code accordingly. The default key length is now 256 bits.
4273 * Fixed SKE key distribution function silc_ske_process_key_material
4274 when the key length is more than 128 bits. The default key
4275 length in SILC is now 256 bits.
4277 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4278 to indicate unsupported algorithm.
4280 * Renamed rijndael.c to aes.c and all functions as well.
4282 * Fixed a long standing channel key setting bug in client library.
4283 Weird that it has never surfaced before.
4285 * Fixed bug in channel deletion. If the entire channel is removed
4286 then it must also delete the references of the channel entry
4287 from the client's channel list as the client's channel entry and
4288 the channel's client entry share same memory.
4290 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Implemented CONNECT and SHUTDOWN commands in the client.
4294 * Implemented CLOSE command to the client.
4296 * Added the function silc_idlist_find_server_by_name into the
4297 files silcd/idlist.[ch].
4299 Added the function silc_idlist_find_server_by_conn into the
4300 files silcd/idlist.[ch].
4302 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * DIE command was renamed to SHUTDOWN. Updated the both code
4307 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4308 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4310 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4313 * Added function silc_server_create_connection function to create
4314 connection to remote router. My server implementation actually
4315 does not allow router to connect to normal server (it expects
4316 that normal server always initiates the connection to the router)
4317 so the CONNECT command is only good for connecting to another
4320 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4323 or some other client was kicked from the channel.
4325 Implemented the handling of the notify type to both client
4328 Implemented silc_server_send_notify_kicked to send the KICKED
4329 notify. It is used to send it to the server's primary router.
4331 * Implemented the KICK command into server and client.
4333 * Added `query' argument to the silc_idlist_get_client function
4334 to indicate whether to query the client from server or not if
4337 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4338 to indicate that the client is not channel founder.
4342 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Removed the rng context from SilcPacketContext structure and
4345 changed that the packet routine uses the Global RNG API.
4347 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Added support for quit message that client can "leave" on the
4350 channel when it quits the SILC. It is ditributed inside the
4351 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4353 Added silc_server_free_client_data that will take the
4354 signoff message as argument.
4356 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4358 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Updated parts of the protocol specification to keep it up
4363 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4366 payloads in one packet.
4368 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4369 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4370 use now the new List flag.
4372 * Also deprecated the following packet types: REPLACE_ID,
4373 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4375 * Added list support for Notify packet in server.
4377 * Added silc_server_send_notify_channel_change to send the
4378 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4379 the silc_server_send_replace_id.
4381 * Added silc_server_send_notify_nick_change to send the
4382 NICK_CHANGE notify type. Deprecates the function
4383 silc_server_send_replace_id.
4385 * Added silc_server_send_notify_join to send the JOIN notify type.
4386 Deprecates the function silc_server_send_new_channel_user.
4388 * Added silc_server_send_notify_leave to send LEAVE notify type.
4389 Deprecates the function silc_server_send_remove_channel_user.
4391 * Added silc_server_send_notify_cmode and
4392 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4393 types. Deprecates the silc_server_send_set_mode function.
4395 * Added SERVER_SIGNOFF notify type to indicate that server has
4396 quit. This means that all clients on the channel from that
4397 server will drop. This can be also used when netsplit happens.
4399 Deprecated REMOVE_ID packet type since it is not needed anymore
4402 Added silc_server_send_notify_server_signoff to send the
4403 SERVER_SIGNOFF notify type. Deprecates the function
4404 silc_server_send_remove_id.
4406 Added also silc_server_send_notify_signoff to send the
4407 SIGNOFF notify type.
4409 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4410 SILC protocol from this day on. Changed the protocol
4411 specification as well.
4413 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4414 notify type. It is used between routers to notify about
4415 topic changes on a channel.
4417 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4420 * Partly updated the protocol specification to comply with the
4421 changes now made. It is still though a bit outdated.
4423 * The JOIN notify type now takes one extra argument <Channel ID>.
4424 The packet used to be destined to the channel but now the
4425 JOIN type may be sent as list thus it is impossible to
4426 destine it to any specific channel. By adding this argument
4427 it is again possible.
4429 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added CREDITS file. The CHANGES and CREDITS file will appear
4432 in the distribution as well.
4434 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4437 types in the server's silcd/packet_receive.c.
4439 * Implemented CMODE and CUMODE to work in router environment.
4441 * Fixed minor encoding and decoding buglet from the
4442 lib/silccore/silcmode.c.
4444 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4447 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4449 * Changed all SilcConfigServer* and silc_config_server* to
4450 SilcServerConfig* and silc_server_config*, respectively.
4453 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Associated the ID (client or server ID) to the Authentication
4456 Payload to avoid any possibility of forging. Updated the
4457 protocol specification and the code accordingly.
4459 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * The RSA key length is now save to the RsaKey context in the
4462 key generation process in lib/silccrypt/rsa.c. The key length
4463 is now used to figure out the maximum size of the block allowed
4464 to be encrypted/signed.
4466 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4467 is equivalent to the silc_mp_mp2bin but does not allocate any
4470 * Changed silc_mp_mp2bin API to take length argument. If it is
4471 non-zero then the buffer is allocated that large. If zero, then
4472 the size is approximated using silc_mp_sizeinbase, which however
4475 * Created Global RNG API which is global RNG that application can
4476 initialize. After initializing, any routine anywhere in the
4477 code (including library) can use RNG without allocating a new
4478 RNG object. This was done to allow this sort of use of the
4479 RNG in code that has no chance to allocate RNG object. All
4480 applications currently allocate this and many routines in the
4481 library use this. Affected file lib/silccrypt/silcrng.[ch].
4483 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4484 it to use the Global RNG API.
4486 * Defined Authentication Payload into protocol specification that
4487 is used during SILC session to authenticate entities. It is
4488 used for example by client to authenticate itself to the server
4489 to obtain server operator privileges.
4491 Implemented this payload into the lib/silccore/silcauth.[ch].
4492 Implemented also routines for public key based authentication
4493 as the new protocol specification dictates.
4495 Moved definitions of different authentication methods from
4496 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4498 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4499 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4500 silc_pkcs_verify_with_hash functions into the file
4501 lib/silccrypt/silcpkcs.[ch].
4503 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * The client entry's userinfo pointer must be always valid.
4506 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4507 will fail since it requires the userinfo. Now, the userinfo
4508 is allocated as "" if actual userinfo does not exist. Actually,
4509 it must exist and it is totally Ok to drop client connections
4510 that does not announce the userinfo. However, we will make
4511 this workaround for now.
4513 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4514 to return the remote port by socket.
4516 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4519 SILC_SERVER_PENDING_EXEC and added an new macro
4520 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4521 data or when error occurs while processing the pending command.
4523 Added new argument `destructor' into silc_server_command_pending
4524 and to the SilcServerCommandPending object. This destructor is
4525 now called after calling the pending callback or if error occurs
4526 immediately. If error occurs the actual pending callback won't
4527 be called at all - only the destructor. The destructor may be
4528 NULL if destructor is not needed.
4530 All this applies for client library code as well. Similar
4531 changes were made there as well for the pending commands.
4533 In the client, the application must now allocate the
4534 SilcClientCommandContext with the silc_client_command_alloc
4537 * Added reference counter to the SilcServerCommandContext. Added
4538 function silc_server_command_alloc and silc_server_command_dup
4541 Same type of functions added to the client library for the same
4544 * Removed the cmd_ident from IDListData away since it is now
4545 global for all connections. It is the command identifier used
4546 in command sending and with pending commands. The affected file
4549 * Added reference counter to the SilcSocketConnection objecet to
4550 indicate the usage count of the object. The object won't be
4551 freed untill the reference counter hits zero. Currently only
4552 server uses this, and client ignores it. The client must be
4553 set to use this too later. The affected files are
4554 lib/silccore/silcsockconn.[ch]. Added also the function
4555 silc_socket_dup to increase the reference counter.
4557 This was mainly added because it is possible that the socket
4558 is removed underneath of pending command or other async
4559 operation. Now it won't be free'd and proper DISCONNECTING
4560 flags, etc. can be set to avoid sending data to connection that
4561 is not valid anymore.
4563 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4564 the connection. After that it sets SILC_SET_DISCONNECTED.
4565 It is, however, possible that the socket data is not still freed.
4566 The silc_server_packet_process now checks that data is not
4567 read or written to connection that is DISCONNECTED. The socket
4568 get's freed when the reference counter hits zero.
4570 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Changed the client operation API: channel_message operation's
4573 `sender' is now the client entry of the sender, not the nickname
4574 and the `channel' is the channel entry, not the channel name.
4576 In the private_message operation the `sender' is now also the
4577 client entry of the sender not the nickname.
4579 Affected file is lib/silcclient/ops.h and all applications
4580 using the client operations.
4582 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Moved the calling of ops->connect() from connect_to_server_final
4585 into receive_new_id functin since that is the point when the
4586 client is actually allowed to send traffic to network. The
4587 affected file is lib/silcclient/client.c.
4589 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4592 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4593 (if needs broadcasting) instead of broadcasting the packets one
4594 by one which would make a burst in the network traffic.
4596 * Added `broadcast' argument to the functions in silcd/server.[ch]
4597 silc_server_create_new_channel[_with_id] to indicate whether
4598 to send New Channel packet to primary router.
4600 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added new function into the silcd/server.[ch] files:
4603 silc_server_create_new_channel_with_id to create new channel with
4604 already existing Channel ID.
4606 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4607 lib/silccore/silcpacket.h. This packet is used t send list of
4608 Set Mode payloads inside one packet. Server uses this to set
4609 the modes for the channels and clients on those channels, that it
4610 announced to the router when it connected to it. The protocol
4611 specification has been updated accordingly.
4613 * The silc_server_new_channel did not handle the packet coming
4614 from normal server as it normally does not send that. However,
4615 when it announces its channels it does send it. Implemented
4616 the support for that.
4618 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4619 into the file lib/silccore/id.h.
4621 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Fixed memory leaks in the functions silc_idlist_del_client,
4624 silc_idlist_del_channel and silc_idlist_del_server in the file
4625 silcd/idlist.c. All of those leaked like a sieve.
4627 * Fixed some small memory leaks in the client's function
4628 silc_client_notify_by_server.
4630 * Added functions into silcd/server.c: silc_server_announce_clients,
4631 silc_server_announce_channels and silc_server_announce_server.
4632 These functions are used by normal and router server to announce
4633 to its primary router about clients, channels and servers (when
4634 router) that we own. This is done after we've connected to the
4637 These functions effectively implements the following packet types:
4638 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4639 and SILC_PACKET_NEW_ID_LIST.
4641 * Added new functions into the silcd/packet_receive.[ch]:
4642 silc_server_new_id_list, silc_server_new_channel_list and
4643 silc_server_new_channel_user_list to handle the incoming
4644 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4646 * Added support of changing Channel ID in the function
4647 silc_server_replace_id. If the server that announces a channel
4648 to the router already exists in the router (with same name but
4649 with different Channel ID), router is responsible to send
4650 Replace ID packet to the server and force the server to change
4651 the Channel ID to the one router has.
4653 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4654 client that the Channel ID has been changed by the router. The
4655 normal server sends this to the client. Client must start using
4656 the new Channel ID as the channel's ID.
4658 Implemented handling of this new type into lib/silcclient/client.c
4659 into the function silc_client_notify_by_server.
4661 * Added new function silc_idlist_replace_channel_id into the files
4662 silcd/idlist.[ch] to replace the Channel ID.
4664 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Call silc_server_command_identify_check always when processing
4667 the IDENTIFY command in silcd/command.c
4669 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4672 send keepalive packets. The packet can be sent by clients,
4673 servers and routers.
4675 Added function silc_socket_set_heartbeat into the file
4676 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4677 If not set, the heartbeat is not performed. The actual
4678 heartbeat is implemented in the low level socket connection
4679 library. However, application is responsible of actually
4682 Added silc_server_send_heartbeat to send the actual heartbeat
4683 packet into silcd/packet_send.[ch]. Server now performs
4684 keepalive with all connections.
4686 * Added silc_task_get_first function into lib/silcutil/silctask.c
4687 to return the timeout task with shortest timeout. There was a bug
4688 in task unregistration that caused problems. TODO has been
4689 updated to include that task system must be rewritten.
4691 * The client library will now resolve the client information when
4692 receiving JOIN notify from server for client that we know but
4693 have incomplete information.
4695 * Rewrote parts of silc_server_remove_from_channels and
4696 silc_server_remove_from_one_channel as they did not remove the
4697 channel in some circumstances even though they should've.
4699 * Encryption problem encountered in server:
4701 The LEAVE command used to send the Channel Key packet to the
4702 router immediately after generating it. However, the code
4703 had earlier sent Remove Channel user packet but not immediately,
4704 ie. it was put to queue. The order of packets in the router
4705 was that Channel Key packet was first and Remove Channel User
4706 packet was second, even though they were encrypted in the
4707 reverse order. For this reason, MAC check failed. Now, this
4708 is fixed by not sending the Channel Key packet immediately but
4709 putting it to queue. However, this is more fundamental problem:
4710 packets that are in queue should actually not be encrypted
4711 because packets that are sent immediately gets encrypted
4712 actually with wrong IV (and thus MAC check fails). So, packets
4713 that are in queue should be encrypted when they are sent to
4714 the wire and not when they put to the queue.
4716 However, the problem is that the current system has not been
4717 designed to work that way. Instead, the packet is encrypted
4718 as soon as possible and left to the queue. The queue is then
4719 just purged into wire. There won't be any fixes for this
4720 any time soon. So, the current semantic for packet sending
4723 o If you send packet to remote host and do not force the send
4724 (the packet will be in queue) then all subsequent packets to the
4725 same remote host must also be put to the queue. Only after the
4726 queue has been purged is it safe again to force the packet
4729 o If you send all packets immediately then it safe to send
4730 any of subsequent packets through the queue, however, after
4731 the first packet is put to queue then any subsequent packets
4732 must also be put to the queue.
4734 Follow these rules and everything works fine.
4736 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added new function silc_server_remove_clients_by_server to
4739 remove all client entries from ID list when the server connection
4740 is lost. In this case it is also important to invalidate all
4741 client entires as they hold the invalid server entry. This
4742 fixes fatal bug when server has lost connection and will reconnect
4745 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Made some sanity checks to silc_server_daemonise like to check
4748 whether the requested user and group actually exists.
4750 * Added sanity check to SKE's silc_ske_responder_finish to check
4751 that the public and private key actually is valid.
4753 * Invalidate the client's nickname when receiving Replace ID
4754 packet and the Client ID is being replaced. This means that the
4755 server will query the nickname if someone needs it (client)
4758 * Sort the ID Cache in client library when the ID Cache data
4759 has changed (needs sorting).
4761 * Do not allow for SILC client to create several connections to
4762 several servers. The client does not support windows right now
4763 and generating multiple connections causes weird behaviour.
4765 Irssi-silc client does support windows and can handle several
4766 connections without problems, see: www.irssi.org and SILC plugin.
4768 * Fixed some places where client was added to the IDList. The
4769 rule of thumb is following (in order to get everything right):
4770 If the client is directly connected local client then the
4771 `connection' argument must be set and `router' argument must be
4772 NULL to silc_idlist_add_client function. If the client is not
4773 directly connected client then the `router' argument must
4774 bet set and the `connection' argument must be NULL to the
4775 silc_idlist_add_client function.
4777 * The funtion silc_server_packet_send_local_channel actually did
4778 not check whether the client was locally connected or not. It
4779 does that now. Fixed a bug related to LEAVE command.
4781 * Fixed Remove Channel User payload parsing bug in server's
4782 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4784 * The server's silc_server_save_channel_key now checks also the
4785 global ID list for the channel as it might not be in the local
4786 list. Fixed a bug related to LEAVE command.
4788 * Is this the end of the [<unknown>] buglet that has been lurking
4789 around for a long time? A little for loop fix in server's
4790 silc_server_command_whois_parse that is used by both IDENTIFY
4791 and WHOIS command. At least, this was a clear bug and a cause
4792 of one type of [<unknown>] buglet.
4794 * WHOIS and IDENTIFY commands call the function
4795 silc_server_command_[whois/identify]_check function even if
4796 we are not router server.
4798 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Added --with-gmp configuration option. If set the GMP
4801 is always compiled in the SILC source tree. If not set then
4802 it is checked whether the system has the GMP3 installed. If
4803 it has then the GMP won't be compiled (the system's headers
4804 and library is used), if it doesn't have it then the GMP is
4805 compiled in the SILC source tree.
4807 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Changed RSA private exponent generation to what PKCS #1
4810 suggests. We try to find the smallest possible d by doing
4811 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4812 not security fix but optimization.
4814 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added new config entry [Identity] to fork the server and run
4817 it as specific user and group. A patch from Bostik.
4819 * Imported Dotconf configuration library into lib/dotconf.
4820 This will be used to create the SILC configuration files later.
4821 It will appear in the distsribution after this commit.
4823 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * A big code auditing weekend happening. Auditing code for
4826 obvious mistakes, bugs and errors. Also, removing any code
4829 Removed files for being obsolete:
4831 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4832 inline in the file lib/silcutil/silcbuffer.h)
4834 o lib/silcutil/silcbufutil.c (the header has inline versions)
4836 Changed code to fix possible error conditions:
4838 o The buffer formatting routines now check that the destination
4839 buffer really has enough space to add the data. This applies for
4840 both buffer formatting and unformatting
4841 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4842 unformatting was changed to accomodate following rules:
4843 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4844 sent to the function while XXX_*STRING will not allocate or copy
4845 the data into the buffer. Instead it sets the pointer from the
4846 buffer into the pointer sent as argument (XXX_*STRING used to
4847 require that the pointer must be allocated already). This change
4848 makes this whole thing a bit more consistent and more optimized
4849 (note that the data returned in the unformatting with XXX_*STRING
4850 must not be freed now). The routines return now -1 on error.
4852 o Tried to find all code that use buffer_format and buffer_unformat
4853 and added return value checking to prevent formatting and
4854 especially unformatting errors and possible subsequent fatal
4857 o Changed ske->x and ske->KEY to mallocated pointers in
4858 lib/silcske/silcske.h. Fixed possible data and memory leak.
4860 o Added return value checking to all *_parse* functions. Fixed
4861 many memory leaks as well.
4863 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4864 so that buffer overflows would not happen. All code now also
4865 checks the return value as it can fail.
4867 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Added reconnection support to server if the normal server looses
4870 its connection to the router (for example if router is rebooted).
4871 The server performs normal reconnection strategy implemented
4872 to the server. Affected file silcd/server.c.
4874 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Added new packet type SILC_PACKET_SET_MODE that is used to
4877 distribute the information about changed modes (for clients,
4878 channels and clients channel modes) to all routers in the
4879 network. Updated the protocol specification accordingly.
4881 Added functions into silcd/packet_send.c and
4882 silcd/packet_receive.c: silc_server_send_set_mode,
4883 silc_server_set_mode.
4885 Added new files silcmode.[ch] into lib/silccore that implements
4886 the encoding and decoding of Set Mode Payload. Added new type
4887 SilcSetModePayload. Moved the definitions of different modes
4888 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4890 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Oops, a little mistake in server's connection authentication
4893 protocol. The protocol is not ended with FAILURE but with
4894 SUCCESS if the authentication is Ok. :) Affected file is
4897 * Implemented NICK_CHANGE notify handling in server in the file
4898 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4899 the local clients on the channel. After the changing nickname
4900 in router environment snhould work and the [<unknown>] nickname
4901 should appear no more.
4903 The silc_server_replace_id function that receives the Replace ID
4904 payload now sends the NICK_CHANGE notify type also in the file
4905 silcd/packet_receive.c
4907 * Changed WHOIS and IDENTIFY command to support the maximum amount
4908 of arguments defined in protocol specs (3328 arguments). This
4909 fixed a bug that caused problems when there were more than three
4912 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added extra parameter, command identifier, to the
4915 silc_client_send_command so that explicit command identifier
4918 Changed that ID list routines uses specific command identifier
4919 when sending WHOIS/IDENTIFY requests to the server so that they
4920 can be identified when the reply comes back.
4922 Affected files lib/silcclient/command.[ch],
4923 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4925 * Added `sender' argument to silc_server_packet_send_to_channel
4926 to indicaet the sender who originally sent the packet to us
4927 that we are now re-sending. Ignored if NULL. Affected file
4928 silcd/packet_send.[ch].
4930 * Added some server statistics support in silcd/server_internal.h
4931 SilcServerStatistics structure and around the server code. Also
4932 send some nice statistics information when client is connecting
4935 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed channel ID decoding in server's JOIN command reply in
4938 silcd/command_reply.c
4940 * Fixed braodcasting of replace ID payload to not to send it if
4941 we are standalone server in silcd/packet_receive.c.
4943 * Fixed all channel message sending routines to not to send
4944 packets to clients that has router set, since they are routed
4945 separately in the same function earlier. Affects file
4946 silcd/packet_send.c and all channel packet sending functions.
4948 * In USERS reply, res_argv[i] are not allocated, the table
4949 is allocated. Thus changed that free the table, not its
4952 * In server's whois_check and identify_check if the client is
4953 locally connected do not send any WHOIS commands - they are not
4956 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Fixed some minor bugs in client when sending WHOIS command. The
4959 arguments was in wrong order.
4961 * Removed statis function add_to_channel from server in
4962 silcd/command.c that was previously used with the joining but
4965 * Tested USERS command in router environment successfully with two
4966 routers, two servers and two clients.
4968 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Reorganized the USERS command and command reply in client library
4971 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4972 When the command is given by user we register a pending command
4973 callback that will reprocess the command after the reply has been
4974 received from the server. When reprocessing the packet we then
4975 display the information. Thus, the USERS information is displayed
4976 now in the command callback instead of in the command reply
4977 callback. The processing of the command is same as previously
4978 when server has sent the command reply in the JOINing process.
4980 * Added to USERS command in silcd/command_reply.c to join the client,
4981 we didn't use to know about, to the channel after we've created
4982 a client entry for it. Also, for clienet we did know already still
4983 check whether it is on the channel or not and add it if not.
4985 * Removed silc_server_command_join_notify as the function and its
4988 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Changed the client's pending command handling to the same as the
4991 server's pending command handling. It is also now possible to
4992 execute command reply functions from other command reply
4993 function as the function callbacks for commands and command
4994 replies are one and same. The pending commands are not static
4995 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4996 in client connection context. Thus, pending commands are server
4997 connection specific as it is convenient.
4999 Changed the function silc_client_command_pending and
5000 silc_client_command_pending_del and added new function
5001 silc_client_command_pending_check. Removed the
5002 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5005 * Added cmd_ident, current command identifier, to the client
5006 connection context in lib/silcclient/client.h to keep track on
5007 command identifiers used in command sending. Client's command reply
5008 function handling now supports the mandatory command identifiers.
5010 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5011 funtions in client to fully support pending command callbacks.
5013 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5014 as one of the arguments to the application in the command reply
5017 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5018 before first releasing SILC but came back. Now it is removed again
5019 and should come back nomore. The FORWARDED flag was used only
5020 by the JOINing procedure by forwarding the command packet to router.
5021 Now, the JOINing procedure has been changed to more generic (due
5022 to various router environment issues) and FORWARDED is not needed
5023 anymore for anything. The protocol specification is yet to be
5026 Now, removed silc_server_packet_forward from server and the flag
5027 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5029 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Renamed NAMES command to USERS command. The NAMES was named that
5032 due to historical reasons. Now it is renamed. Also, rewrote
5033 parts of the USERS command. The nickname list is not sent anymore
5034 by the server. Only Client ID and mode lists are sent in the USERS
5035 command. Changed this also to the protocol specification.
5037 The client now resolves the names and stuff after it receives
5038 the USERS list from the server when joining to the channel.
5040 * WHOIS and IDENTIFY commands has been changed to support multiple
5041 Client ID's per command. One can now search for multiple users
5042 in the network by sending only one WHOIS or IDENTIFY command.
5043 Changed the code and the protocol specifications.
5045 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5046 uses silc_server_command_whois_parse to parse the request. */
5048 * If normal server, do not parse the WHOIS and IDENTIFY requests
5049 before sending it to the router. Saves some time.
5051 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Fixed JOIN command on client library. Wrong number of arguments
5054 used to crash the client.
5056 * Added silc_server_channel_has_global function to check whether
5057 channel has global users or not.
5059 * Added silc_server_channel_has_local function to check whether channel
5060 has locally connected clients on the channel.
5062 * The silc_server_remove_from_one_channel now checks whether the
5063 channel has global users or not after given client was removed from
5064 the channel. It also checks whether the channel has local clients
5065 on the channel anymore. If it does not have then the channel entry
5066 is removed as it is not needed anymore.
5068 * The silc_server_notify now checks on JOIN notify whether the joining
5069 client is one of locally connected or global. If it is global then
5070 the channel has now global users on the channel and that is marked
5071 to the channel entry. Also, it now saves the global client to
5072 global list who is joining and JOINs it to the channel. This is
5073 for normal server, that is.
5075 Changed silc_server_send_notify_on_channel,
5076 silc_server_packet_relay_to_channel and
5077 silc_server_packet_send_to_channel check if we are normal server
5078 and client has router set (ie. global client) do not send the
5079 message to that client, as it is already routed to our router.
5081 * Implemented LEAVE notify type handling in silc_server_notify
5084 * Tested LEAVE command in router environment successfully. Tested
5085 with two routers, two servers and two clients.
5089 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5091 * Implemented SIGNOFF notify type handling in silc_server_notify
5094 * silc_server_remove_id now removes the client entry from all channels
5095 it has joined and thusly sends SIGNOFF notify type.
5097 * Rewrote the NAMES list generation in server by removing two excess
5098 loops. The lists are created now inside one loop.
5100 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * silc_server_remove_channel_user checks now also global list
5103 for channel and client.
5105 * silc_server_new_channel_user checks now both local and global
5106 list for channel and client. Fixed a bug in client id decoding.
5107 Used to decode wrong buffer.
5109 * silc_server_channel_message checks now both local and global
5110 list for channel entry.
5112 * Tested channel joining (hence JOIN) in router environment
5113 successfully. Tested with two routers, two servers and two
5116 * Tested channel message sending in router environment successfully.
5118 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Added silc_server_save_channel_key into server.[ch] to save the
5121 received channel key in Channel Key payload processing. It is
5122 also used in JOIN command reply handling.
5124 Equivalent function silc_client_save_channel_key added into
5125 client.[ch] into client library.
5127 * Changed JOIN command reply to send information whether the channel
5128 was created or not (is existing already) and the channel key
5129 payload. Changed protocol specs accordingly.
5131 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5132 the request was sent by ID and not by nickname. Crashed on
5135 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5138 now correctly save the received data.
5140 * silc_server_free_sock_user_data now notifies routers in the
5141 network about entities leaving the network.
5143 At the same time implemented functions silc_server_remove_id
5144 and silc_server_send_remove_id to receive and send REMOVE_ID
5145 packets. The packet is used to notify routers in the network
5146 about leaving entities. The ID removed will become invalid in
5149 * Added function silc_idlist_del_server into server. Removes and
5150 free's server entry from ID list.
5152 * silc_server_private_message function now checks, if we are router,
5153 that the destination ID really is valid ID, naturally.
5155 * In router when NEW_ID packet is received (for new client) the
5156 hash of the Client ID is saved in the ID Cache but the
5157 client->nickname is set to NULL, instead of putting the hash
5160 IDENTIFY command now also checks that client->nickname must be
5161 valid. If it is not if will request the data from the server who
5162 owns the client. Added new function
5163 silc_server_command_identify_check.
5165 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5166 to set the command to already allocated Command Payload.
5168 * Tested private message sending in router environment with two
5169 routers, two servers and two clients. Fixed minor bugs and now
5172 * Fixed segfault from client's NAMES command. Used to crash if
5175 * Forwarded packets must not be routed even if it is not destined
5176 to the receiver. Changed server code comply with this.
5178 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Added `require_reverse_mapping' boolean value to ServerParams
5181 structure. If TRUE (not default) the server will require that
5182 the connecting host has fully qualified domain name.
5184 If the reverse mapping is not required and hostname could not be
5185 found the IP address is used as hostname.
5187 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Implemented version string checking to both client and server.
5190 The check is incomplete currently due to the abnormal version
5191 strings used in development version of SILC.
5193 * Changed all command functions in server to use the new
5196 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Changed char *data to unsigned char *data in ID Cache system to
5199 support binary data as ID Cache data. Changed code to support
5200 binary data in lib/silccore/idcache.c.
5202 * Renamed silc_server_packet_relay_command_reply to
5203 silc_server_command_reply as it is normal packet receiving
5204 function. Rewrote the function to accept command replys for
5205 servers and not only for clients.
5207 * Mark remote router always as registered server if we are connecting
5208 to it. Otherwise, commands sent by the router to us are ignored.
5210 * All ID List find routines now returns the ID Cache Entry pointer
5211 as well if requested.
5213 * WHOIS command works now in router environment, tested with two
5214 routers, two servers and two clients.
5216 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5217 in router environment (as it is almost equivalent to WHOIS) but
5218 hasn't been tested thoroughly. Added new functions:
5220 silc_server_command_identify_parse
5221 silc_server_command_identify_send_reply
5222 silc_server_command_identify_from_client
5223 silc_server_command_identify_from_server
5225 * Disabled route cache adding because adding two different ID's with
5226 same IP replaces the old cache entry thus giving wrong route.
5227 The entry->router->connection is always the fastest route anyway
5228 so route cache may not be needed. Of course, new routes maybe
5229 established after receiving the ID when the entry->router->connection
5230 might not be anymore the most optimal.
5232 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Add route cache for received ID for fast routing.
5236 * Added silc_server_packet_route to route received packet on router
5237 that is not destined to us.
5239 * Renamed silc_server_get_route to silc_server_route_get.
5241 * Added id_string and id_string_len fields into SilcServer to
5242 include encoded ServerID for fast comparing without excess
5243 encoding of the ID's.
5245 * Cleaned up WHOIS command on server side. Added following static
5248 silc_server_command_whois_parse
5249 silc_server_command_whois_check
5250 silc_server_command_whois_send_reply
5251 silc_server_command_whois_from_client
5252 silc_server_command_whois_from_server
5254 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5255 arguments in command replies. All command functions should be
5256 updated to use this macro.
5258 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Minor typo fixes on command reply handling on server.
5262 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added silc_server_command_add_to_channel internal routine to add
5265 the client to the channel after router has created the channel and
5266 sent command reply to the server.
5268 * Added generic silc_server_send_command to send any command from
5271 * Use static buffer with ID rendering instead of duplicating data.
5273 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Fixed a channel user mode bug when joining to a channel server gave
5276 everybody channel founder rights, oops.
5278 * We mark ourselves as the router of the incoming server connection
5279 if we are router ourselves. This way we can check in some packet
5280 sending functions whether it is locally connected server. For
5281 incoming router connections we put NULL.
5283 * For router sending packets locally means now always sending the
5284 packet cell wide; to local clients and local servers. For normal
5285 server sending packet locally means sending it to only local
5288 * Fixed the JOIN command to really work in router environment. If the
5289 channel is created it is always created by the router. Router is
5290 also responsible of making the initial joining to the channel,
5291 sending JOIN notify to the sending server and distributing
5292 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5293 does not exist server doesn't do anything else but forward the
5294 command to the router which performs everything.
5296 * Added silc_server_send_channel_key function to send the Channel Key
5299 * Added silc_server_create_channel_key to create new channel key. The
5300 channel key is now re-generated everytime someone joins or leaves
5301 a channel, as protocol dictates. Note: channel->key_len is the
5304 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5307 packet_receive.[ch] to separate packet sending and receiving
5308 routines. The server.[ch] now includes everything else including
5309 actual packet processing (writing and reading data) and other
5312 Renamed silc_server_private_message_send_internal to
5313 silc_server_send_private_message. The routine is still though
5314 used only to relay private messages as server does not send
5315 private messages itself.
5317 Renamed silc_server_new_channel to silc_server_create_new_channel
5318 and added new function sicl_server_new_channel that handles the
5319 incoming New Channel packet. Added also new sending function
5320 silc_server_send_new_channel to send New Channel Payload.
5322 * Added new function silc_server_notify to process incoming notify
5323 packet to the server/router. Server may then relay the notify
5324 to clients if needed.
5326 * Added new function silc_server_new_channel_user to process incoming
5327 New Channel User packet. Router will redistribute the packet and
5328 send JOIN notify to its local clients and locally connected servers
5329 if needed. Normal server will send JOIN notify to its local client
5330 on same channel when received this packet. Added also corresponding
5331 sending function silc_server_send_new_channel_user to sent the
5334 * Added boolean route argument to send_notif_to_channel and
5335 packet_send_to_channel functions to attempt to route the packet
5336 if it is TRUE and send only locally if it is FALSE.
5338 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * silc_server_replace_id now broadcasts the received replace ID
5341 packet if it is not broadcast packet already. The router must
5342 broadcast to inform other routers about changed ID.
5344 * Added backpointer to server's router into SilcServer context in
5345 silcd/server_internal.h.
5347 * Fixed silc_server_packet_broadcast to send correct broadcast
5350 * The channel key is now distributed to the local client as soon
5351 as it is received from the router (in router environment) so that
5352 no other packet may be sent for the channel until client has
5355 * silc_server_remove_channel_user now broadcasts the received
5356 Remove Channel User packet if it is not broadcast packet already.
5357 The router must broadcast to inform other routers about removed
5360 * Added users field into SilcPacketContext that is a reference count
5361 of the context. One can increase the reference count by calling
5362 silc_packet_context_dup which is now changed to just increase the
5363 reference count instead of duplicating the data. The reference
5364 count is decresed by calling silc_packet_context_free that will
5365 free the data after the reference count hits zero.
5367 For now on the packet context and everything allocated into it
5368 (including the raw packet from network) must be freed by calling
5369 the new silc_packet_context_free function. Added also new function
5370 silc_packet_context_alloc that must be used now to allocate the
5371 context. This also means that if a routine is asynchronous from
5372 silc_[client/server]_packet_parse_type the packet context must
5373 be duplicated by calling silc_packet_context_dup. Otherwise it
5374 gets free'd after silc_[client/server]_packet_parse_type returns.
5375 Also, one must remember that if packet is duplicated then its
5376 reference count must be decresed by calling the free function as
5377 many times as it was duplicated.
5379 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5380 from both client and server.
5382 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Made joining to a channel working in router environment.
5386 * Cleaned up JOIN command on server side and create function
5387 silc_server_command_join_channel internal routine to make the
5390 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Changed silc_command_pending list to SilcDList. Also, added
5393 `ident' field to SilcServerCommandPending structure to identify
5394 the reply and to call correct callback.
5396 Added silc_server_command_pending_check function to replace the
5397 corresnponding macro. The silc_command_pending list is not
5400 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5401 to set identifier to previously allocated Command Payload. It
5402 is used to set identifier for command when resending Command
5405 * Added silc_command_payload_encode_payload to encode Command
5406 Payload buffer from SilcCommandPayload structure.
5408 * Added silc_argument_payload_encode_payload to encode Argument
5409 payload buffer from SilcArgumentPayload structure.
5411 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Changed WHOIS command to support router connection on server side.
5414 The whois request is always sent to router unless the server is
5415 standalone server. After server has received the reply from the
5416 router will it send the reply to the client.
5418 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5419 broadcast received broadcast packet. The function is used only
5420 by router. The broadcast packet is always sent to the router's
5423 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5424 render given ID to printable string, for log files for example.
5426 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Made basic router to router connections working. At least they
5429 can now connect to each other but nothing really works the way
5430 they are supposed - yet.
5432 * Added new initiator token to RouterConnection configuration
5433 file in silcd/serverconfig.[ch]. It is used to tell whether we
5434 are the initiator to the remote router or whether we'll expect
5435 the other end to connect.
5437 * Moved registering of listener task to silc_server_init, hence
5438 the server starts listenning as soon as it is run, even if it
5439 does not have connections to other routers. Let's see how well
5442 * Changed default connection retry timeouts for more suitable in
5445 * Removed cipher and such arguments from silc_idlist_add_client
5446 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5447 Added new function silc_idlist_add_data to add the keys and stuff
5450 * Added SilcIDListData structure and added it to SilcClientEntry
5451 and SilcServerEntry as their first field in the structure. This
5452 way we can explicitly cast the ID entries to the SilcIDListData
5453 structure and get common data for the entries. In past, we had
5454 to first check what type of connection it is and then cast it to
5455 correct ID entry type. Now, we can directly cast the opaque
5456 pointer to the SilcIDListData (no matter what ID entry it actually
5457 is) and get the data needed.
5459 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5462 in some circumstances even if threre were timeout tasks, though not
5463 IO tasks, but tasks anyway. Now fixed.
5465 * Defined SilcServerConnection structure to hold connection specific
5466 stuff about directly connected servers and routers. The definition
5467 is currently in silcd/server_internal.h. I thought about having
5468 a bit more important role fro this struct but for now it is used
5469 only when connecting to other server (or router actually).
5471 * Added connecting retry support in server when connecting to
5472 router(s). The retry feature implement exponential backoff
5473 algorithm. Also, added SilcServerParams structure to hold default
5474 parameters for server. For now, it include these retry settings
5475 and are hard coded. After server is moded to be as Silc Server
5476 Library this structure will be more important.
5478 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Changed client librarys channel->clients table to SilcList and
5481 changed code accordingly.
5483 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Changed client's channel table to SilcList and changed code
5486 accordingly. Also changed SilcChannelClientEntry to include back-
5487 pointer to the channel so that client entry can use that structure
5488 as list as well and we have fast cross-reference to the channel.
5489 This change dramatically decreased the complexity of channel
5490 handling with client entry and vice versa (removed one extra
5491 loop when searching for channel entry from many functions).
5493 * Changed server->sim from table to SilcDList and changed code
5496 * NAMES command can now be used from user interface. It will show
5497 the user list on the channel, neatly.
5499 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5500 Code now saves realname of the user if it becomes available.
5502 * Renamed configure.in to configure.in.pre and made ./prepare
5503 script to automatically add correct version string to
5504 configure.in which it creates from configure.in.pre.
5506 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * NAMES command reply now shows users mode with the nickname when
5511 * Moved silc_client_ch[u]mode[_char] functions from
5512 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5513 place sucks, they are utility functions and should be in some
5516 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5518 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5521 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added TRQ (efficient deque and list library) into lib/trq. This is
5526 a very good list library that is currently used in the SILC. Defined
5527 SilcList API over the library because I didn't like the API very
5528 much. See lib/trq/silclist.h for the API and examples of how to
5529 use the API. Fixed various places in the code to use the new
5530 SilcList API. The SilcList is meant for lists that has a structure
5531 already defined as a list. It is not suitable to add just some
5532 context to the list (in TRQ, the context is the list actually).
5534 So, I defined SilcDList that can be used for the purpose where
5535 predefined list structure does not exit. This can be used as
5536 such list. Now some context just can be added to the SilcDList.
5537 Currently this list is not used in the SILC just yet, though there
5538 are a lot places where this can replace dynamically allocated
5539 tables and I will fix these places, later, to use SilcDList.
5540 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5541 and use TRQ internally).
5543 Also fixed some annoying warning messages that the original TRQ
5544 code generated. Also minor changes to TRQ's Makefile.in.
5546 * Added support for querying by Client ID to both WHOIS and
5547 IDENTIFY commands into server, as required by the protocol.
5549 * Removed method function pointers from SilcBuffer structure. They
5550 weren't used to anything and just increased the context size for
5551 no good reason. This change also made silc_buffer_alloc and
5552 silc_buffer_free functions inline functions.
5554 * Disabled command flooding detection support until it's fixed so
5555 that it accepts commands in but does not execute them more than once
5558 * Added silc_net_localhost(), to return local hostname, into
5559 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5560 that must be initialized before calling silc_client_init.
5562 * Added new function: silc_server_send_notify_on_channels to send
5563 notify messages to all channels client has joined. It is assured
5564 that the message is sent only once per client.
5566 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5567 lib/silcutil/silcutil.[ch] as silc_format function. The new
5568 function is generic and is used by server as well, not only by
5569 the logging routines.
5571 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5572 the provided version string was not acceptable. Added new function:
5573 silc_ske_check_version into lib/silcske/silcske.h. The function
5574 must be implemented by the application (client or server) and it
5575 does not reside in the SKE library. The function checks the version
5576 string remote end sent.
5578 * Added back pointers (to opaque context and to SilcSocketConnection)
5579 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5581 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5582 duplicate packet context structure.
5584 * Changed `notify' client operation to send same arguments as client
5585 receives from server except for ID's. ID's are mapped to correct
5586 ID entry and that is returned. Also, if channel entry is not sent
5587 by server but the notify is for channel the channel entry is sent
5588 to application (otherwise application doesn't know that it is for
5589 channel (library gets it from packet's Destination ID)).
5591 * Added silc_client_remove_from_channels into client library to
5592 remove a client from all channels it has joined to. Used when
5593 received SIGNOFF notify from server. Added also new function
5594 silc_client_replace_from_channels to replace old ID entry with
5595 new ID entry on all channels. Used when received NICK_CHANGE
5598 * Fixed ID Cache list handling in silc_idlist_get_client in
5599 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5600 to get (or query) client by ID.
5602 * Updated TODO list.
5604 * Added connection authentication status message defined by the
5605 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5606 support for these into the code in client and server side.
5608 * Added generic function silc_client_send_command to send any command
5609 with variable argument list. Application should use this function
5610 to send commands if the command functions provided by the library
5611 does not suite for the application's user interface needs.
5613 * Added new `failure' client operation. Application is notified about
5614 received failure packet if client is executing a protocol. In this
5615 case the protocol's execution has failed.
5617 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5618 is required by the protocol.
5620 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5621 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5624 * Added status flag to SilcSKE object to indicate realtime status
5625 of the SKE protocol.
5627 * Application receives now exactly same command reply arguments as
5628 the library receives from server. However, if ID is received the
5629 corresponding ID entry is returned to the application (eg. Client
5630 ID is mapped to correct SilcClientEntry entry and that is returned).
5631 Changed command_reply client operation due to this change.
5633 * Changed all ID's in commands and in command replys as ID Payloads.
5634 Change affected both client and server side codes.
5636 All ID's sent in SILC network (with execption of ID's in SILC
5637 Packet header) are sent in ID Payload to support variable length
5640 * Server now notifies nick changes and notifies all clients on
5641 the channels about the new nickname (about the new Client ID,
5644 * Implemented CMODE command to change channel modes. Supports all
5645 channel modes defined by the protocol specs except ban and invite
5646 lists. (Also, private channel key mode is supported but support for
5647 setting private channel key in client is missing, thus, this mode
5648 has no effect on client side (except that server requires that the
5649 client uses private channel key and normal channel traffic does not
5652 Also, invite mode works per se, but INVITE command does not work
5653 yet correctly, so you can set channel as invite only channel but
5654 inviting clients to the channel does not work (it is yet to be
5655 thought what's the best way to do it).
5657 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5658 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5659 Implemented CUMODE command to change user's mode on the channel.
5660 Supports all modes defined by the protocol specs.
5662 * Added NAMES command reply to return users modes on the channel.
5664 * Removed unnecessary and slow ciphers from lib/silccrypt.
5666 * Set SO_KEEPALIVE option to connection sockets by default.
5668 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5670 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5671 redefined the Notify Payload into protocol specs.
5673 * Added silc_id_payload_parse_id to get ID directly from raw
5676 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5679 accept searching by Client ID as well.
5681 * Added support for LEAVE and SIGNOFF notify types in client library.
5683 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5684 to parse ID Payload from raw data.
5686 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Added flags parameter into silc_ske_assemble_security_properties
5689 function in lib/silcske/silcske.[ch].
5691 * Changed notify client operation to fit better for notify messages
5692 sent by server. The notify payload received from server is now
5693 passed to the application (after parsing it to SilcNotifyPayload).
5694 It is application's responsibility to retrieve the arguments
5695 from the payload and show the message the way it wants. The message
5696 sent by server is implementation specific.
5698 * Changed public keys to comply with the protocol specification.
5699 Old public keys are not supported anymore and are not compatible.
5701 * Removed nickname from Channel Payload as the latest draft removed
5702 it. The client must resolve the nickname from the NAMES command
5703 reply received when it joined the channel.
5705 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5707 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Fixed some errors in protocol specification drafts.
5711 * Created lib/silccore/silcnotify.c to implement Notify Payload
5712 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5713 generic payloads described by protocol specifications. The file
5714 includes implementations for ID Payload and Argument Payload.
5716 * Changed Command Payload implementation to use the new Argument
5717 Payload. Changed command_xxxx_payload to command_payload_xxxx
5718 to comply with SILC coding conventions.
5720 * Added suppport for Argument Payload handling in Notify Payload
5721 implementation as protocol requires it. Added the new support
5722 into server and client lib as well.
5724 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added support for multiple nicknames on same channel. [n] is
5727 added locally to the nickname if there are more than one same
5728 nicknames on the channel.
5730 * Server now sends all nicknames that matched WHOIS request.
5731 Client also shows the list received from server.
5733 * Added TOPIC command to client side. User can now set and show
5734 current topic on channel.
5736 * Added MOTD command to client and server. Also, server sends the
5737 motd when client connects to the server.
5739 * Changed version strings to comply ISO 8601.
5741 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Fixed protocol error handling in client library. It should now
5744 cope even if the SKE fails for some reason.
5746 * Made new protocol specification drafts for submitting to IETF.
5748 * Implemented TOPIC command to server in silcd/command.c.
5750 * Added two new notify types into lib/silccore/silcnotify.h:
5751 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5752 notify nickname change and topic setting/change on a channel.
5754 * API change of command_reply operation in client library. The
5755 application gets now the status type received from server as well.
5757 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5761 * Cras fixed and optimized the packet handling even further and
5762 it should work now. Minor change to the prototype of function
5763 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5765 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Added new function into lib/silcutil/silcschedule.[ch]:
5768 silc_schedule_with_fd to select() a specified fd. The function
5769 returns after timeout expires or data arrives or goes. The
5770 function is used by packet routines to wait that all data is
5771 received from network.
5773 * Fixed data reading from network in lib/silccore/silcpacket.c.
5774 The code now assures that all data is read from the fd and then
5775 continues packet processing. This was a bug fix since the code
5776 used to drop some data in some circumstances.
5778 * Added new function into lib/silcclient/client.[ch]:
5779 silc_client_start_key_exchange to start key exchange after
5780 connection has been established to server. The code internally
5781 now uses this funtion but its main purpose was to provide it
5782 for applications that perform their own connecting. After
5783 application has created a connection it merely calls this
5784 function to start the key exchange between client and server.
5785 The library takes care of everything else after that.
5787 Updated also lib/silcclient/README to explain the usage of
5790 * Do not send to application information that connection has
5791 been established. Application gets notified it by connect
5794 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5796 * Applied cras's patch to add silc_schedule_one function. The
5797 function runs scheduler once and returns.
5799 * Fixed the scheduler after cras messed it up. The timeout
5800 handling works now as it's supposed to work.
5802 * Added into lib/silccore/ silcnotify.h to include notify
5803 message types support. Changed silc_server_send_notify*
5804 functions, in server.[ch], to support those new notify types.
5805 Added the support for the notify types into client library,
5806 as well. Added new notify client operation into ops.h in
5809 * Changed silc_server_packet_send_to_channel to send normal
5810 packets instead of just channel message packets. The function
5811 is now used to send the notify packets to channels. It is not
5812 used to send channel message packets anymore, as server never
5815 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5816 va_arg()s as it seems to require it nowadays. I guess, if SILC
5817 is compiled with older va_arg() the new code should work anyway.
5819 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Splitted core library. Core library (lib/silccore) includes
5822 now only SILC protocol specific core (and common) components.
5823 Created new utility library (lib/silcutil) that includes more
5824 generic purpose stuff. The stuff for util library was taken
5825 from the old core library. This was minor and easy split.
5827 * Created SILC Client Library (lib/silcclient) that includes
5828 implementation of the SILC client without user interface. This
5829 was major move from silc/ directory. The code has been changed
5830 so that it is transparent towards the user interface. The
5831 silc/ directory includes now the same user interface as before
5832 and it uses the new client library. Read lib/silcclient/README.
5833 Basicly, the client library performs everything else related
5834 to SILC except user interface handling. Also, configuration
5835 files are considered to be part of user interface and library
5836 does not handle them.
5838 This change also changed a lot of structures, function naming etc.
5839 Most important change was that SilcClientWindow object was
5840 renamed to SilcClientConnection in the client library. Created
5841 also new file lib/silcclient/ops.h. Also added new files
5842 silc/local_command.[ch] and silc/client_ops.[ch].
5844 All these changes were made to make it easier for user interface
5845 designers to create what ever user interface for the SILC client
5848 It is also expected that the server will be moved to lib
5849 directory as well and SILC Server Library will be created;
5850 sometimes in the future.
5852 * Removed Local commands from lib/silccore/silccommand.h as
5853 they are application specific and new client library does not
5854 handle any of those anymore.
5856 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5857 old client implementation in silc/.
5859 * Added support for callback functions in SILC_LOG_* macros.
5860 Application can now set its own callbacks that will be called
5861 instead of using the default functions that will always print
5862 the debug messages to stderr (or stdout). Also, debugging can
5863 now be disabled by setting silc_debug to FALSE and re-enabled by
5864 setting it to TRUE. Note, that logging will still work even
5865 if debugging is disabled.
5867 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5868 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5869 silc_log_reset_debug_callbacks.
5871 * To enable debugging in silc client one must give now -d
5872 option on command line.
5874 * Changed silc_schedule_init to automatically allocate task queues
5875 if they are not allocated before calling it.
5877 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added GMP 3.1 into math library.
5881 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5884 a channel in SILC network. The packet is used by servers and
5885 routers to notify other routers that user has left a channel.
5886 This little feature was missing until now. Added the feature
5887 to protocol specification as well.
5889 Added functions: silc_server_send_remove_channel_user and
5890 silc_server_remove_channel_user into server.[ch].
5892 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5893 lib/silccore/silcpacket.h. However, they are not implemented
5896 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Fixed joining to a channel and sending channel messages
5899 between server and router. The channel message sending should
5900 now work inside a cell.
5902 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Fixed the private message sending between server and router.
5905 The private message sending should now work inside a cell.
5907 * Added silc_server_replace_id into server.[ch] to replace
5908 existing ID in the SILC network.
5910 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5911 and silc_idlist_replace_server_id into idlist.[ch] in server.
5913 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Fixed the server to server connections. Server can again now
5916 connect to router. Router to router connections probably does
5919 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added dynamic protocol registering support. Now protocols can
5922 registered and unregistered on the fly. Patch by cras.
5924 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added lib/contrib directory to hold routines that some platforms
5927 don't have but are needed by SILC.
5929 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5930 into lin/contrib to provide getopt() and getopt_long() for
5931 those who don't have it.
5933 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Added AWAY command to client. When away message is set and
5936 client receives a private message packet the client automatically
5937 replies to the sender with the away message.
5939 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5940 bug seemed to be the cause of recent problems when compiling
5943 * Added version detection support to SKE protocol specification
5944 and added the new changes to the SKE implementation as well.
5945 There were other minor changes in the SKE protocol as well.
5947 Many changes in lib/silcske/silcske.[ch] and in
5948 lib/silcske/payload.[ch].
5950 * Added ^U functionality, clear input line. Patch from cras.
5952 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Mainly small bugfixes on core library. Fixed some debugging
5955 logging and buffer overflow in silclog.c.
5957 * Updated config.sub and config.guess on the distribution tree.
5959 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Added command lagging support in server. Client may execute
5962 commands now only once in two seconds.
5964 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Optimized packet reception. MAC computation and checking is now
5967 also more optimized. A lot previously duplicated code is now
5968 used as generic by both client and server.
5970 * Fixed key pair generation in clientutil.c
5972 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Added into lib/silccore/silcbufutil.[ch] new function;
5975 silc_buffer_realloc.
5977 * Moved generic packet sending/encryption functions to
5978 lib/silccore/silcpacket.[ch] from client and server. Some
5979 rewriting of the functions.
5981 * Moved all generic packet reception/decryption functions to
5982 lib/silccore/silcpacket.[ch] from client and server. The
5983 packet processing is now much cleaner in both client and server.
5984 These were major changes in both client and server.
5986 * Created many common functions in server to do packet sending.
5987 Previously code were duplicated a lot, this has been removed
5990 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Rewrote major parts of the ID cache system. Don't know
5993 whether it is better now or not but at least the API is more
5996 * Major rewrite on ID cache stuff on client because of the ID
5997 cache API changes. Added idlist.c to client.
5999 * Also major rewrite on ID cache stuff on server as well.
6000 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6001 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6002 in hand, instead they are all put into the ID cache system now.
6003 All server_idlist_* routines uses ID cache now instead of
6004 traversing its own lists (those lists does not exist anymore).
6005 SilcIDList though still exists. Also, SilcXXXEntry's are
6008 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Finally made the SKE implementation compliant to the protocol
6011 specification. All mp integers are now binary encoded as
6012 opposed being HEX encoded.
6014 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6017 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6018 functions: silc_[encode/decode]_pem. Also added function
6019 silc_encode_pem_file to PEM encode with newlines ('\n') for
6022 * SILC public keys are now encoded either PEM or binary. Same
6023 option is for private keys as well. By default private keys
6024 are binary encoded and public keys PEM encoded. Silly HEX
6025 encoding were removed.
6027 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6028 function to create fingerprints.
6030 * Fixed a bug in SHA1; does not change the original data anymore.
6032 * Partly implemented INFO command on client and server side.
6033 Fixed CLEAR command. Changes to SERVER command; show current
6034 server(s) when giving command without arguments. Added
6035 VERSION command to client.
6037 * Added check to server that unregistered connections cannot
6038 execute commands (unless it is specificly allowed).
6040 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Fixed screen refresh.
6044 * Fixed channel joining bug from client. On some circumstances
6045 client tried to join to a channel it had already joined.
6047 * Added public key verification process into client's protocol.c.
6048 The client now verifies the public key from user and saves
6049 it into ~./silc/serverkeys/ directory.
6051 Added into: clientutil.[ch]: silc_client_verify_server_key.
6053 * Changed SKE protocol's silc_ske_initiator_finish function
6054 to accept callback function that verifies the received public
6055 key. Removed old silc_ske_verify_public_key function.
6057 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6060 silc_pkcs_private_key[_data]_set.
6062 * Made the password and public authentication more cleaner in
6063 server's protocol.c.
6065 * Removed historic and obsolete protocol `channel_auth' from
6066 both client and server.
6068 * Removed wrong way of sending command status messages from
6069 server to client in server's command.c. The old way violated
6070 protocol specification.
6072 Changes to silccore/silccommand.[ch]: removed
6073 silc_command_encode_status_payload -> not needed anymore,
6074 changed silc_command_encode_payload_va to accept extra
6075 argument on variable argument list. The argument type must
6076 now be provided to the function. Also, added new function:
6077 silc_command_encode_reply_payload_va which is same as
6078 normal command_encode_payload_va except command status type
6079 is provided as extra argument.
6081 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added ~./silc directory handling. The directory includes the
6084 public and private keys for the client.
6086 Added silc_client_check_silc_dir, silc_client_create_identifier
6087 and silc_client_load_keys.
6089 * Implemented SILC protocol compliant public key. Added public
6090 and private key saving to and loading from files.
6092 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6093 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6094 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6095 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6096 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6098 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6099 silc_pkcs_load_[public/private]_key.
6101 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Added silc_server_get_route (route.[ch]) to get connection
6104 data for the fastest route for given ID.
6106 * Implemented INVITE command on client and server. The command
6107 were re-defined in the SILC Protocol Specification and the
6108 implementation now complies with the specification.
6110 * Implemented PING command on client and server.
6112 * Implemented NAMES command on client and server. The server side
6113 supports currently only normal server not router server yet.
6114 Some changes to NAMES definition in SILC protocol specification.
6116 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Implemented LEAVE command on client and server.
6120 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6121 again. This change was made to the protocol as well. Server
6122 should not violate the protocol specification anymore.
6124 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6127 was tested. SOCKS4 was not but should work anyway.
