1 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed CMODE command when new channel key was created. If
4 the creation failed the old key was removed. Next time giving
5 same command would crash the server since the old key was
6 freed already. Affected file silcd/command.c.
8 * Fixed the silc_server_announce_get_channels to not crash
9 on reconnect. Affected file silcd/server.c.
11 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
13 * Added silc_log_set_debug_string function to set a regex
14 string to match for debug output. Only the function names,
15 or filenames matching the given debug string is actually
16 printed. This way it is possible to filter out those debug
17 strings that user is not interested in.
19 Fixed a bug in silc_string_regexify.
21 Affected files lib/silcutil/silclog.[ch], and
22 lib/silcutil/unix/silcunixutil.c.
24 * Changed the -d options in both server and Irssi SILC client
25 to take the debug string as argument. Affected files
26 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
28 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
30 * Added silc_hash_babbleprint to create a Bubble Babble
31 Encoded fingerprint. The encoding is developed by Antti
32 Huima (draft-huima-babble-01.txt), and it creates human
33 readable strings out of binary data. Affected file
34 lib/silccrypt/silchash.[ch].
36 * Print the babble print now in addition of fingerprint as well
37 in Irssi SILC client. Affected files are
38 irssi/src/fe-common/silc/module-formats.[ch],
39 irssi/src/fe-common/silc/core/client_ops.c.
41 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Fixed a security problem found in SKE. The initiator's
44 public key too is now added to the HASH hash value creation
45 which is signed by the responder to create the SIGN value.
46 This will prevent anyone in the middle to lie to the responder
47 about the initiator's public key. If this is done now, the
48 man in the middle will get caught. Updated the protocol
51 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
53 * Better installation directory handling. Configure module
54 paths and other paths automatically to example_silc* files
55 in doc/. A patch by toma.
57 * Fixed compiler warning from MPI library, and from SILC RNG.
60 * Added SILC_SERVER_PID_FILE to define the pid file for server.
61 It can be configured with ./configure. A patch by toma.
63 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
65 * Find correct make to use in prepare-clean. A patch by
66 toma. Affected file prepare-clean.
68 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>

87 * Added silc_pkcs_public_key_compare to compare two
88 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
90 * Check that the client who set the founder mode on the
91 channel is the same client that is giving the founder
92 mode to itself. It is done by comparing the saved public
93 key (it is saved even in the authentication is passphrase).
94 Affected file silcd/command.c.
96 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
98 * Do not process packet for disconnected socket connection.
99 Affected file lib/silccore/silcpacket.c.
101 * Process the DISCONNECT packet through scheduler in the
102 client library. Affected file lib/silcclient/client.c.
104 * Fixed the silc_client_packet_parse to not to increase
105 the packet sequence number if the conn->sock and the
106 current socket connection is not same. This can happen
107 for example during key agreement when the conn includes
108 multiple socket connections (listeners). Affected file
109 lib/silcclient/client.c.
111 * The sender of the file transfer request now provides also
112 the pointer (listener) for the key exchange protocol. If
113 the listener cannot be created then it sends empty key
114 agreement and lets the receiver provide the listener.
116 Added `local_ip' and `local_port' arguments to the
117 silc_client_file_send. If they are provided they are used,
118 if not then it will attempt to find local IP address, if
119 not found or bind fails then the remote client will provide
122 Affected files are lib/silcclient/client_ftp.c and
123 lib/silcclient/silcapi.h.
125 * Extended the FILE SEND command to support defining the
126 local IP and port for key exchange listener. They are
127 optional. Affected file irssi/src/silc/core/silc-servers.c.

131 * Defined to WHOIS command reply the sending of fingerprint
132 of the client's public key (if the proof of posession of the
133 corresponding private key is verified by the server).
134 Updated to the protocol specification.
136 * Added support of receiving the client's public key's
137 fingerprint in command reply in client library. Affected
138 file is lib/silcclient/command_reply.c, and
139 lib/silcclient/idlist.[ch].
141 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Do not send over 128 chars long nickname to the server
144 in NICK command. Affected file lib/silcclient/command.c.

152 twice for same socket context. Affected file is
155 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Send error message to application if opening file for
158 writing during file transfer fails. Affected file is
159 lib/silcclient/client_ftp.c.
161 Remove all file transfer sessions for a client that we're
162 removing from ID cache.
164 Affected file is lib/silcclient/client_ftp.c.

194 client library. Affected file lib/silcclient/client_prvmsg.c.
196 * Do not actually remove the client directly from ID cache
197 during SERVER_SIGNOFF, but invalidate it. This way we
198 preserve the WHOWAS info for the client. Affected file
201 * Fixed SERVER_SIGNOFF notify handling in the server. The
202 server is now able to process incoming SERVER_SIGNOFF notify
203 for a server that it doesn't even know about. It will remove
204 the clients provided in the notify. Affected file
205 silcd/packet_receive.c.
207 * Check for partial packet in data queue after every packet that
208 was found from the queue. Return and wait for more data if
209 there is partial data in queue. Affected file is
210 lib/silccore/silcpacket.c.
212 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

220 * Check that newsize in silc_buffer_realloc is larger than
221 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
223 * Added better monitor of file transfers. It now monitors
224 key agreement protocol during the file transfer too. Added
225 error reporting too. Affected files
226 irssi/src/silc/core/silc-servers.c,
227 irssi/src/fe-common/silc/module-formats.[ch].
229 * Wrote a help file for FILE command.
231 * Added silc_rng_global_get_byte_fast to get not-so-secure
232 random data as fast as possible. Random data is read from
233 /dev/urandom if available and from the SILC RNG if not
234 available. It is used in padding generation. Affected file
235 lib/silccrypt/silcrng.[ch].
237 * All packets in client library are now processed synchronously.
238 Optimized packet processing a lot. Affected file
239 lib/silcclient/client.c.
241 * All server connection packets are processing synchronously
242 now in server, to optimize packet processing. Affected file
245 * Include files are installed now only in Toolkit distribution
246 if make install is given. Affected files: all Makefile.am's.
248 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
250 * Assure that silc_client_notify_by_server_resolve does not
251 resolve the client information multiple times. If it cannot
252 be found by the first it cannot be found at all. Affected
253 file lib/silcclient/client_notify.c.
255 * Fixed WHOWAS command reply calling. Affected file
256 lib/silcclient/command_reply.c.
258 * Removed all references to silc_idlist_get_client from the
259 Irssi SILC client since that call is internal call used by
260 the library. The Irssi SILC client will use now client
261 retrieval functions found in silcapi.h.
263 * Fixed a bug in resolving nickname info before sending
264 private message. It used freed memory. Affected file
265 irssi/src/silc/core/silc-servers.c.
267 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

286 * Added silc_net_localip to return local host's IP address.
287 Affected file lib/silcutil/silcnet.[ch].
289 * If key exchange or rekey protocol is active for a connection
290 parse all packets syncronously since there might be packets
291 in packet queue that we are not able to process without first
292 processing packets before them. Affected file silcd/server,
293 lib/silcclient/client.c.
295 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
296 whether library should continue processing the packet.
297 Affected file lib/silccore/silcpacket.h.

332 * Resolve the client info when received private message or
333 channel message for a client which nickname we don't know.
334 Affected files lib/silcclient/client_prvmsg.c and
335 lib/silcclient/client_channel.c.
337 * Do not crash in /KEY if client is not connected. Affected
338 file irssi/src/silc/core/silc-channels.c.
340 * Added SilcClientStatus field to the SilcClientEntry in the
341 lib/silcclient/idlist.h.
343 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
344 is incomplete and is being resolved, it won't be resolved
347 Make sure also that USERS command reply does not resolve
348 twice information. Affected file is
349 lib/silcclient/command_reply.c.
351 Make sure that silc_client_get_clients_by_list does not
352 resolve twice same information.
354 * Check for valid client->id in the silc_server_free_client_data.

380 * Redefined the SILC packet header to include the padding
381 length. Affected file lib/silccore/silcpacket.[ch].
383 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
384 length for maximum padding up to 128 bytes). Affected
385 file lib/silccore/silcpacket.h.
387 * Removed all backwards support for old 0.5.x MAC thingies.
388 The SILC packet header change makes it impossible to be
389 backwards compatible.
391 * Send the ENDING packet with timeout in the backup resuming
392 protocol. This is to assure that all routers has connected
393 to the primary router. Affected file silcd/server_backup.c.
395 * Changed the RNG to take the first IV from random data. It
396 used to take it from zero actually. Changed the RNG also
397 to use /dev/urandom during session. /dev/random is used
398 in initialization. Affected file lib/silccrypt/silcrng.[ch].
400 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Changed the SILC packet header to have the first two bytes
403 (the packet length) encrypted. Affected files aroung the
404 code tree, lib/silccore/silcpacket.[ch]. Removed the
405 SilcPacketCheckDecrypt callback. It is not needed anymore
406 since the silc_packet_receive_process will determine now
407 whether the packet is normal or special.
409 * Implemented the unidirectional MAC keys. Affected files
410 lib/silcske/silcske.c, silcd/protocol.c and
411 lib/silcclient/protocol.c.

418 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
420 * Allow backup router to announce servers. All servers
421 announced by backup router are added to the global list
422 automatically. Update hte server's socket to our primary
423 router also when backup router announces a server.
424 Affected file silcd/packet_receive.c.
426 * Do not update the client->router in the function
427 silc_server_udpate_clients_by_server if the client is on
428 global list. We might fail to find any specific server
429 for locally connected clients and local cell clients. They
430 should still use the `from' and not `to' as client->router.
431 This fixes backup router resuming protocol. Affected file
434 * Decrease channel statistics count only if the channel
435 deletion worked. Affected files are silcd/server.c and
438 * Added silc_server_update_servers_by_server to update origin
439 of all server entries. Used during backup router protocol.
440 Affected files silcd/server_util.[ch], silcd/server.c. and
441 silcd/backup_router.c.

446 lib/silccrypt/silchmac.c.
448 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
450 * Assure that router cannot reroute the same channel message
451 to the sender. Affected file silcd/packet_receive.c.
453 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
455 * Made better checks that the channel message is not sent
456 to the router it came from. Affected file is
457 silcd/packet_send.c. Fixed memory leak too.
459 * Announce informations for incoming router connection, but
460 only after checking if it is replaced by backup router.
461 Affected file silcd/packet_receive.c.
463 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Fixed the backup resuming protocol to work in multiple
466 router environment. Affected file silcd/server_backup.c.
468 * Route packet only to one router in the function
469 silc_server_packet_send_to_channel. Affected file is
472 * Fixed silc_server_send_notify_dest to set the broadcast
473 flag. Fixed the silc_server_send_notify_topic to actually
474 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
475 Affected file silcd/packet_send.c.
477 * Changed the SFTP Filesystem interface. Changed the
478 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
479 the filesystem operation function. The SilcSFTPFilesystem
480 is now a context that is allocated by all filesystem allocation
481 functions and it already includes the operations structure
482 and filesystem specific context. It is given as argument
483 now to the silc_sftp_server_start. This made the interface
484 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
485 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
487 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Changed the backup router adding and getting interfaces
490 in the server. The router that will be replaced by the
491 specified backup router is now sent as argument. Affected
492 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
495 * Added silc_net_addr2bin_ne to return the binary form of
496 the IP address in network byte order. Affected files
497 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].

507 in upstream or downstream. Affected file is
510 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
512 * Wrote the definition of the backup resuming protocol to the
513 protocol specification.
515 * Removed one redundant channel key generation from normal
516 server during joining procedure. Removed one redundant
517 channel key sending from server to router during joining
518 procedure. Affected file silcd/command.c.
520 * Made minor bugfixes to the backup router resuming protocol.
521 Affected file silcd/server_backup.c, server.c.
523 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

530 resume the primary router position in the cell after the
531 primary router comes back online. Affected files
532 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
533 and silcd/server_util.[ch].
535 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
537 * Sleep two (2) seconds after sending QUIT command to server.
538 Affected file lib/silcclient/command.c.
540 * Assure that if outgoing data buffer is pending do not force
541 send any data. Affected file silcd/packet_send.c.
543 * Assure that if outgoing data buffer is pending do not force
544 send any data. Affected file lib/silcclient/client.c.
546 * Implemented the backup router support when the primary router
547 goes down. The servers and routers can now use the backup
548 router as new primary router without loosing connectivity.
550 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
552 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
553 in the server to indicate disabled entry. All data read
554 from the connection will be ignored and no data is sent
555 for entry that is disabled. Affected files are
556 silcd/idlist.h, silcd/server.c.
558 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
560 * Created SFTP client and server test programs in the
561 lib/silcsftp/tests directory.
563 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Implemented memory filesystem (virtual filesystem) for
566 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
569 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
571 * Implemented the SFTP (SSH File Transfer Protocol) to the
572 lib/silcsftp. It includes SFTP client and SFTP server
575 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
577 * Moved lib/silccore/silcprotocol.[ch] to the
578 lib/silcutil library.
580 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
581 take variable argument list pointer as argument. Affected
582 file lib/silcutil/silcbuffmt.[ch].
584 * Added silc_buffer_set function that is used to set data
585 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
586 Affected file lib/silcutil/silcbuffer.h.
588 * Changed various routines in the core library to use the new
589 silc_buffer_set instead of allocating new buffer only for
592 * Added 64-bit value formatting and unformatting support to the
593 silc_buffer_[un]format routines. Affected file is
594 lib/silcutil/silcbuffmt.[ch].
596 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
597 to includes/bitmove.h.
599 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
601 * Fixed channel user mode saving in client library. Affected
602 file lib/silcclient/command[_reply].c.
604 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Defined the file transfer to the SILC Protocol. Added
607 new packet type SILC_PACKET_FTP and defined File Transfer
608 Payload. The mandatory file transfer protocol is SFTP
609 (SSH File Transfer Protocol). Affected file in addition
610 of the internet draft is lib/silccore/silcpacket.h.
612 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
613 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
614 is used as part of backup router protocol when the primary
615 router of the cell is back online and wishes to resume
616 the position as primary router.
618 * Redefined the MAC generation keys in the protocol. The
619 same key is not used anymore in both direction. Both
620 direction will now use different keys for sending and
621 receiving. This fixes a potential security flaw. This
622 change causes incompatibilities in the protocol.
624 * Redefined also the MAC computation from the packet.
625 An packet sequence number is now added to the MAC
626 computation. This prevents possible replay attacks against
627 the protocol. This change too causes incompatibilities
630 Added `sequence' field to the SilcPacketContext to hold
631 the current sequence number for the packet.
633 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
635 * Added `created' field to the SilcIDListData in the file
636 silcd/idlist.h to indicate the time when the entry was
639 * Added `created' field to the SilcChannelEntry too. Affected
642 * Added `creation_time' aguments to all the announcement functions
643 in the server. If it is provided then only the entries that
644 was created after the provided time frame are actually
645 announced. Affected file silcd/server.[ch].
647 * The protocol says that the Channel ID's IP address must be
648 based on the router's IP address. Added check for this in
649 the silc_server_new_channel when processing incoming New Channel
650 Payload. Affected file silcd/packet_receive.c.
652 * Print out the correct version with --version in SILC client.
653 Affected file irssi/src/silc/core/silc-core.c.
655 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
657 * Fixed WHOWAS command to check for completnes of the client
658 entry always, not just when the command is coming from client.
659 Affected file silcd/command.c.
661 * Added new function silc_server_packet_queue_purge to purge the
662 outgoing data queue to the network. After the function returns
663 it is guaranteed that the outgoing packet queue is empty.
664 Affected file silcd/packet_send.[ch].
666 * Purge the outgoing packet queue in the rekey protocol's final
667 callback to assure that all rekey packets go to the network
668 before quitting the protocol. Affected file silcd/server.c.
670 * Added silc_client_packet_queue_parse as similar function as
671 in server to the client library. The affected file is
672 lib/silcclient/client.c.
674 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
676 * Splitted silcd/server.c and created silcd/server_util.[ch]
677 for utility functions.
679 * Added new socket flag SILC_SF_DISABLED to indicate that the
680 connection is open but nothing can be sent to or received from
681 the connection. Affected file lib/silcutil/silsockconn.[ch].
682 The checking for disabled socket is checked in the low level
683 silc_socket_write and silc_socket_read functions.
685 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Allow only nicknames and channel names that fits into the
688 7-bit unsigned char ASCII set. Affected file silcd/command.c.
690 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
692 * When processing JOIN command reply in server check that if
693 the channel exists in our global list we'll move it the local
694 list. Affected file silcd/command_reply.c.
696 * Fixed the check whether client is joined on the channel already
697 in JOIN command. Affected file lib/silcclient/command.c.
699 * Fixed the JOIN command reply to check whether the channel
700 already exists. Affected file lib/silcclient/command_reply.c.
702 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Added silc_ske_status_string to map the SKE error numbers
705 to readable strings. The affected files are
706 lib/silcske/silcske[_status].[ch].
708 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Do not show the private channels on the WHOIS channel list
711 as it is not allowed by the protocol. The affected file is
714 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
716 * Assure that the packet length digged from the actual packet
717 is something sensible in the silc_packet_decrypt_rest_special
718 in lib/silccrypt/silcpacket.c.
720 * Free and NULL the allocated pointer in silc_hmac_alloc if
721 the HMAC allocation fails. The affected file is
722 lib/silccrypt/silchmac.c.
724 * Print the selected security properties to the log files in
725 the server. Affected file silcd/protocol.c.
727 * Add SKE's reference counter even if calling the completion
728 callback manually. Otherwise it goes negative, although it
729 does not cause any problems. The affected file is
730 lib/silcske/silcske.c.
732 * Remove the client entry with short timeout after giving the
733 KILL command. Affected file lib/silcclient/command.c.
735 * Fixed to send error reply in WHOIS and IDENTIFY commands in
736 case all found clients are already disconnected (WHOWAS would
737 found them) in the server. Affected file silcd/command.c.
739 * Update the last_receive (time of last data received) to be
740 updated only when received private or channel message so that
741 the idle time showed in WHOIS makes more sense.
743 * Added boolean field `valid' in to the SilcClientEntry in the
744 client library to indicate whether the entry is valid or not.
745 This fixes the nickname change bug on channel when changing
746 the nickname to be same than the old (like nick to Nick) the
747 nickname formatter doesn't set the new nick anymore to Nick@host.
748 Affected file lib/silcclient/idlist.[ch].
750 * Now actually fixed the nickname changing on disconnection.
751 Added new function silc_change_nick to the Irssi SILC Client.
752 Affected file irssi/src/silc/core/client_ops.c,
753 irssi/src/silc/core/silc-nicklist.[ch].
755 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Check that the public key exists in the GETKEY command before
758 trying to encode it. Affected file silcd/command.c.
760 * Print some notifications on received public keys with GETKEY
761 command in the Irssi SILC Client. Affected files are
762 irssi/src/fe-common/silc/module-formats.[ch],
763 irssi/src/silc/core/client_ops.c.
765 * Use IDENTIFY command to resolve the server information in the
766 GETKEY command instead of INFO command. Affected file
767 lib/silcclient/command.c.
769 * All command reply functions in the client library now calls
770 the pending command reply callbacks even if an error has
771 occurred. The server has done this a long time and now it was
772 time to move the client library to this as well. Now all
773 errors can be delivered back to the pending command reply
774 callbacks if necessary. Affected files are
775 lib/silcclient/command[_reply].[ch].
777 * Change the nickname on disconnection back to the username
778 because in reconnect the server will enforce it to it anyway.
779 Affected file irssi/src/silc/core/silc-servers.c.
781 * Fixed a config file parsing bug in the Irssi SILC client.
782 Affected file irssi/src/silc/core/clientconfig.c.
784 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
786 * When printing the channel mode on JOIN, verify that the
787 channel key and channel's HMAC are valid. Affected file
788 irssi/src/silc/core/client_ops.c.
790 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
792 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
793 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
794 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
796 * Removed channel key rekey task deleting from the function
797 silc_server_save_channel_key. Affected file silcd/server.c.
798 Added explicit timeout task context instead that is used to
799 delete the task if we are registering a new task before the
800 new task has elapsed.
802 * When channel key rekey occurs the client library now saves
803 the old channel key for a short period of time (10 seconds) and
804 is able to use it in case some is still sending channel
805 messages encrypted with the old key after the rekey. Affected
806 file lib/silcclient/[idlist.h|client_channel.c].
808 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
810 * Added check to the silc_server_new_id_real to not accept
811 new ID if it is the sender's own ID. Affected file is
812 silcd/packet_receive.c.
814 * Assure that we do not announce ourself or the one we've
815 sending our announcements when we're router and are announcing
816 servers to our primary router. Affected file silcd/server.c.
818 * Fixed silc_server_command_identify_check_client to assemble
819 correct WHOIS packet. It send corrupted WHOIS packet and
820 caused problem with router to router connections. Affected
821 file silcd/command.c.
823 Fixed also silc_server_command_whois_check the same way
824 as for the IDENTIFY command.
826 * Added new SilcIDListStatus to the server in the SilcIDListData
827 structure. The status now includes the current status of
828 the entry (like registered, resolved etc.). Affected file
829 silcd/idlist.[ch]. Defined a bunch of different status types
830 as well. This replaced the old boolean registered field as well.
832 Added resolve_cmd_ident field to the SilcClientEntry structure
833 too so that if the entry is for example being resolved so
834 another command may attach to the same pending command reply
835 without requiring to resolve the same entry again. This concept
836 should optimize the WHOIS and the IDENTIFY resolving under
837 heavy load by taking away unnecessary resolving for entries
838 that are being resolved already.
840 Added support for adding multiple pending commands for one
841 command idenfier. Affected file silcd/command[_reply].[ch].
843 * Fixed WHOIS and IDENTIFY save to remove the cache entry
844 before deleting the data. Otherwise the hash table will have
845 freed data in comparison functions. Affected file is
846 silcd/command_reply.c.
848 * Fixed silc_idlist_replace_client_id to add the new entry to
849 the cache with NULL nickname. Otherwise there will be invalid
850 memory as the nickname after the nickname is freed. Affected
851 file silcd/packet_receive.c.
853 * Fixed the silc_idlist_get_clients_by_hash. The entries was
854 saved into wrong slots because the previous number of entries
855 was not taken into account. Affected file silcd/idlist.c.
856 Fixed same thing in silc_idlist_get_clients_by_nickname too.
858 * If we are router and we receive JOIN notify to a channel that
859 does not have any users then notified client is marked as the
860 channel founder, as it is it. The affected file is
861 silcd/packet_receive.c
863 * Added to the extended hash table API's table_del_*ext functions
864 the destructor as argument too, so that the caller can decide
865 which destructor to use or whether to use destructor at all.
866 Affected file lib/silcutil/silchashtable.[ch].
868 * Fixed ID Cache purging. It actually deleted the entries from
869 the hash table after the data was freed. The hash table ended
870 up comparing freed memory. The affected file is
871 lib/silccore/silcidcache.c.
873 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
875 * Fixed Irssi SILC client's KILL command's HELP syntax.
877 * The USERS command now resolves the detailed user information
878 if the userinfo field is missing. Affected file is
879 lib/silcclient/command_reply.c.
881 * Do not print error in silc_file_read if the read file does
882 not exist. Just silently return NULL. Affected file is
883 lib/silcutil/silcutil.c.
885 * Fixed the silc_log_output to not wine about NULL filename
886 and to not create some bogus " " filename. Affected file is
887 lib/silcutil/silclog.c.
889 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Fixed various printing bugs on the user interface in the
892 Irssi SILC Client. Minor changes that were forgotten from
895 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Fixed the configure.in.pre and the compilation and distribution
898 environment to support the new autoconf 2.52. That version is
899 now required to compile the CVS trunk.
901 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
903 * Renamed function silc_parse_nickname to silc_parse_userfqdn
904 to generally parse user@fqdn format strings. Affected file
905 lib/silcutil/silcutil.c.
907 * Added nickname_format and nickname_force_format fields to the
908 SilcClientParams structure. The first one defines the format
909 for the nicknames that the library will enforce if the receives
910 multiple same nicknames. The second one is boolean value and
911 can be used to force the library to always enforce the format
912 to the nicknames regardles whether there are multiple nicknames
913 or not. This configurable formatting was employed to flexibly
914 support accessing multiple nicknames from the user interface.
915 The userinterface can now set the nicknames to what ever format
916 they prefer. Affected file lib/silcclient/silcapi.h.
918 Added function silc_client_nickname_format to the file
919 lib/silcclient/idlist.c. It performs the nickname formatting.
921 Added new field `hostname´ to the SilcClientEntry context.
922 It holds the hostname of the client. Affected file is
923 lib/silcclient/idlist.h.
925 * Irssi SILC Client sets the nicknames in nick@hostn format.
926 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
927 irssi/src/silc/core/silc-core.c.
929 The WHOIS printing now also shows both the real nickname and
930 the formatted nickname so that user knows how to access the
931 user if there are multiple same nicknames cached. Affected
932 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
933 printing formatting too to take the hostname now as a separate
934 argument. The Affected file is
935 irssi/src/fe-common/silc/modules-formats.[ch].
937 * Changed the silc_client_get_clients_local to accept the formatted
938 nickname as argument. It accepts the real nickname too but the
939 formatted nickname can be used to find the true entry from
940 multiple entries. Affected file lib/silcclient/silcapi.h and
941 lib/silcclient/idlist.c.
943 * Added nickname_format_parse field to the SilcClientParams.
944 It is a callback function provided by the application to parse
945 the nickname out of the formatted nickname string. The library
946 calls it to get the nickname from the formatted string. Since
947 the application generally knows better the format of the nickname
948 string it parses it instead of the library, even though library
949 encodes the formatted string. If the callback function is not
950 provided then the library will use the string as is. The
951 affected file is lib/silcclient/silcapi.h.
953 * All the nickname strings passed to the client library in
954 commands are now expected to be formatted nickname strings.
955 If the command does not support the formatted nickname string
956 it will assume that the sent string is the actual nickname.
957 Affected file lib/silcclient/command.c.
959 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Added public key authentication support to OPER and SILCOPER
962 commands in the client library. Affected file is
963 lib/silcclient/command.c.
965 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Changed the get_auth_methdod client operation to be asynchronous.
968 It can be async if the application resolves the authentication
969 method from the server during the negotiation. Added new
970 SilcGetAuthMeth completion callback that the application will
971 call after resolving the authentication method.
973 Added function silc_client_request_authentication_method that
974 the application can use to resolve the authentication method
975 from the server. Added also SilcConnectionAuthRequest callback
976 that the library will call after the server has replied. The
977 application can call this function if it does not know the
978 current authentication method.
980 Affected files are lib/silcclient/client.c and
981 lib/silcclient/silcapi.h.
983 * The Irssi SILC client now automatically resolves the authentication
984 method incase any configuration information is not present (and
985 currently there never is). The affected file is
986 irssi/src/silc/core/client_ops.c.
988 * Fixed public key authentication from the client library.
989 Affected file lib/silcclient/protocol.c. Changed also the
990 protocol specification about the public key authentication in
991 the connection authentication protocol. The actual data to be
992 signed is now computed with a hash function before signing.
994 * Fixed the public key authentication from the server as well.
995 Affected file silcd/protocol.c.
997 * Removed the mlock()'s from the memory allocation routines.
998 Affected file lib/silcutil/silcmemory.c. The ./configure does
999 not check anymore for the mlock(). Affected file is
1002 * Fixed USERS command in server to allow the execution of the
1003 command for private and secret channels if the client sending
1004 the command is on the channel. Affected file silcd/command.c.
1006 * Fixed silc_client_get_clients_local to return the clients
1007 count correctly. It could return wrong value. Affected file
1008 lib/silcclient/idlist.c.
1010 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1013 types. The assembler optimizations seemed not to like 64-bit
1014 data types. The assmebler optimizations thus are now enabled
1015 also for BSD systems as opposed to only enable them for Linux.
1017 * Do not check for threads at all on BSD systems. Affected
1018 file configure.in.pre.
1020 * Removed -n and -h options from the Irssi SILC Client since
1021 they are not used in silc.
1023 * Fixed the prime generation to assure that the first digit
1024 of the generated random number is not zero since our conversion
1025 routines does not like number strings that starts with zero
1026 digit. If zero digit is seen the random number is regenerated.
1027 This caused some corrupted RSA keys when the zero first digit
1028 was met. Affected file lib/silcmath/silcprimegen.c.
1030 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * Fixed WIN32 configuration in the ./configure script.
1033 Fixed to include xti.h on environments that has it.
1034 Patches by Carsten Ilchmann and andrew.
1036 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1038 * Changed the silc_id_create_client_id to be collision
1039 resistant. It is now assured that there cannot be created
1040 two same client ID's. I suspect that some weird bugs in
1041 the server were actually caused by duplicate Client IDs.
1042 Affected file silcd/serverid.[ch]. A router receiving
1043 new ID now also assures and informs the sending server
1044 if the ID caused collision.
1046 * Changed the silc_id_create_channel_id to also assure that
1047 there are no collisions.
1049 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Statement about ignoring the Mutual Authentication flag when
1052 performing rekey with PFS was a bit misleading. It is ignored
1053 if it was set in the initial negotiation, it cannot be even
1054 set in the rekey. Fixed in the ke-auth draft. Started the
1055 new versions of the protocol drafts in the doc/.
1057 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Fixed a bug in silc_client_command_identify_save when saving
1060 new channel information. The channel name was no duplicated
1061 and caused crash on exit. Affected file is
1062 lib/silcclient/command_reply.c.
1064 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Fixed the getkey command handling in the server. Send just
1067 empty OK reply to the sender if the key could not be fetched
1068 (but everything else was ok, like the key just was not available).
1069 Changed the public key parameter to optional in the protocol
1070 specs so that empty OK reply can be sent. Affected file
1073 Added a message to Irssi SILC client to tell to user if the
1074 server did not return a public key.
1076 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Fixed a channel key regeneration bug. It registered new
1079 timeout tasks exponentially until all system resources were
1080 used. Affected file silcd/server.c.
1082 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1084 * Added the SILC Document generator to the scripts/silcdoc.
1085 It can be used to generate the Toolkit Reference Manual out
1086 of the source tree. Internally it will also use the RoboDoc
1087 generator now imported in util/robodoc.
1089 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Added couple of return's in rekey protocol if error orccurred
1092 during the protocol. The execution must be terminated.
1093 Affected file silcd/protocol.c. Also, terminate the protocol
1094 always with timeout.
1096 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * The client's Client ID was created initally from the wrong
1099 nickname (it could have been in format nick@host) in the
1100 silc_server_new_client. Affected file silcd/packet_receive.c
1102 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Added some SILC_LOG_ERROR's to various error conditions
1105 if client could not be added to ID cache. Affected files
1106 silcd/packet_receive.c and silcd/server.c.
1108 * When client's sock->user_data is freed, NULL also the
1109 client->router and client->connection pointers. Added check
1110 for these pointers being NULL to various places around the
1111 code. Affected file silcd/server.c.
1113 * Added client->data.registered == TRUE checks to various
1114 places around the code to assure that unregistered client's
1115 are not handled when it is not allowed. Affected file
1118 * Added `bool registered' fields to all
1119 silc_idlist_[server|client]_get_* routines to indicate whether
1120 the fetched client needs to be registered or not. Affected
1121 file silcd/idlist.[ch].
1123 * Add your own entry as registered to the ID cache in the
1124 server. Affected file server.c.
1126 * Fixed a bug in silc_server_new_server. The SilcServer was
1127 set as the new server's context instead of SilcServerEntry.
1128 This naturally caused some weird bugs.
1130 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * Do not delete the channel rekey task when adding it
1133 for in silc_server_create_channel_key.
1135 * Changed the silc_server_create_channel_key to return
1136 TRUE or FALSE to indicate the success of the channel key
1139 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Fixed MSVC++ project files and added missing files to

1147 does not have it defined. Affected files are
1148 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1150 * Fixed buffer overflow from Irssi SILC Client. Affected
1151 file irssi/src/fe-common/core/themes.c.
1153 * Fixed double free in client library in the file
1154 lib/silcclient/client.c when disconnecting from server.
1156 * Applied double free patch from cras to Irssi SILC client.
1157 Affected files irssi/src/core/[modules/expandos].c
1159 * Fixed the disconnection handling to Irssi SILC Client.
1160 The application must call silc_client_close_connection
1161 in ops->connect client operation in case of failure of
1162 the connection. Affected file is
1163 irssi/src/silc/core/client_ops.c.
1165 * Do not set sock->protocol to NULL in the function
1166 silc_client_close_connection after executing the protocol's
1167 final callback since the sock might not be valid anymore.
1168 Affected file lib/silcclient/client.c.
1170 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Do not enable SILC_THREADS if the linking with libpthread
1173 did not happen. Affected file configure.in.pre.
1175 * Added notion to protocol specification that server must
1176 verify the sent authentication payload with CMODE when
1177 setting the channel founder key. Implemented it to the
1178 server. Affected file silcd/command.c.
1180 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Added _EXTRA_DIST SILC distribution variable to the
1183 distributions file. It is used to conditionally add extra
1184 files or directories to the specific distribution. Affected
1185 files ./prepare, Makefile.am.pre and distributions.
1187 Removed the `_' from the start of the distribution names.
1190 * Added README.WIN32 for instructions to compile the Toolkit
1193 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1195 * Fixed a double free in disconnection in the server. Affected
1196 file is silcd/server.c.
1198 * Fixed the lib/silcske/groups.c to work now also with GMP
1199 MP library. The string conversion did not work when using
1200 specific base and the base is indicated in the string as well.
1202 * Created win32/ directory which now includes MSVC++ specific
1203 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1204 It will appear only in the toolkit distribution
1206 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Changed the key material distribution function in case when
1209 the hash output is too short. The data is now concatenated
1210 a bit differently than it used to. Made the change to the
1211 SKE protocol specification.
1213 * Added better GMP detection to configure.in.pre. A patch
1216 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Fixed a minor bug in SKE that might cause some problem on
1219 some platforms. Affected file lib/silcske/silcske.c.
1221 * Added the cookie checking for initiator in the SKE. It checks
1222 that the responder returns the sent cookie unmodified. The
1223 affected file is lib/silcske/silcske.c. Added new SKE
1224 error type INVALID_COOKIE that can be sent during the
1225 negotiation. Fixed some memory leaks as well.
1227 * Added the "invalid cookie" error message to Irssi SILC client's
1230 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Added `task_max' field to the SilcClientParams to indicate
1233 the maximum tasks the scheduler can handle. If set to zero,
1234 default values are used. Affected file lib/silcclient/silcapi.h.
1236 * Fixed memory leaks in silc_client_close_connection. Affected
1237 file lib/silcclient/client.c.
1239 * Added silc_client_del_client_entry to client library to free
1240 all memory of given client entry. Affected file is
1241 lib/silcclient/idlist.[ch].
1243 * Added new functions silc_client_del_channel and
1244 silc_client_del_server to delete channel and server entries.
1245 Affected file lib/silcclient/[silcapi.h/idlist.c].
1247 * Removed silc_client_del_client_by_id from silcapi.h.
1249 * Fixed the INFO command to return the server's own info
1250 correctly when querying by Server ID. Affected file is
1253 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * Removed the non-blocking settings in WIN32 code in the
1256 silc_sock_[read/write] and added SleepEx instead. Affected
1257 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1258 of input data is now checked with FIONREAD and ioctlsocket.
1260 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1262 * Call silc_schedule_task_del_by_context in the
1263 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1264 Affected file lib/silccore/silcprotocol.c.
1266 * Call silc_protocol_cancel for active protocols in the
1267 silc_server_close_connection if the funtion
1268 silc_server_free_sock_user_data has not been called.
1269 Affected file silcd/server.c.
1271 * Generic tasks cannot be deleted using the del_by_fd
1272 task deleting function since generic tasks does not match
1273 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1275 * Added a notion to SILCOPER help file that the SILCOPER works
1276 only on router server, not on normal server.
1278 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Added for WIN32 support for the new scheduler as well.
1281 Affected file lib/silcutil/win32/silcwin32schedule.c.
1283 * Fixed the SHA1 implementation to work on various platforms.
1285 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1288 API. It is part of the scheduler now. Everything else is
1289 as previously but some functions has changed their names.
1290 Checkout the lib/silcutil/silcschedule.h for the interface.
1291 Updated all applications to use the new interface. Affected
1292 files are lib/silcutil/silcschedule.[ch].
1294 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Found a bug in the SKE implementation. The HASH value,
1297 specified by the protocol, was not computed correctly. The
1298 public key of the responder was not added to the computation
1299 even though it is mandatory. Affected file lib/silcske/silcske.c.
1300 This unfortunately causes incompatibilities with older
1301 clients and servers.
1303 * Added WIN32 specific network init and uninit functions:
1304 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1305 the Winsock2. Affected file lib/silcutil/silcnet.h and
1306 lib/silcutil/win32/silcwin32net.c.
1308 * Set the socket always to nonblocking mode on WIN32 after
1309 reading data or writing data. Affected file is
1310 lib/silcutil/win32/silcwin32sockconn.c.
1312 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Fixed various compilation problems under WIN32. Affected
1315 files lib/silcutil/win32/silcwin32thread.c and
1316 lib/silcutil/win32/silcwin32schedule.c.
1318 * Removed all _internal.h #includes from public header
1319 files. Internal headers must never be included from
1322 Removed also the lib/silcske/payload_internal.h file.
1324 * All include files that may be needed (public and some others
1325 included by the public headers) by application developers are
1326 now copied to the ./includes directory. It does not copy any
1327 internal headers. Affected file Makefile.defines.pre and all
1328 Makefile.am's under lib/ and subdirs.
1330 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * Do not change the ~/.silc directory's permissions automatically.
1333 Affected file irssi/src/silc/core/clientutil.c.
1335 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Do not cancel the protocol in silc_server_close_connection
1338 it might cause recursion. Now cancelled in the function
1339 silc_server_free_sock_user_data. Affected file silcd/server.c.
1341 * Fixed the silc_server_remove_clients_by_server to regenerate
1342 the channel keys correctly finally. Added also new function
1343 silc_server_remove_clients_channels to actually do it.
1344 Affected file silcd/server.c.
1346 * Fixed the silc_server_new_channel to not crash by giving
1347 wrong router to the new channel. Affected file is
1348 silcd/packet_receive.c.
1350 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1353 which is given as argument to the silc_client_alloc now.
1354 It can be used to configure the client and set various parameters
1355 that affect the function of the client.
1357 * The USERS command in server did not check whether the channel
1358 is private or secret. Affected file silcd/command.c.
1360 * Added new argument to the USERS command in protocol specification.
1361 The USERS command now can take the channel name as argument
1362 as well. Added support for this in client and server and
1363 updated the protocol specs.
1365 * Completed the GETKEY command in client. It can be now used
1366 to fetch also servers public key not only some clients.
1367 Affected files lib/silcclient/command[_reply].c.
1369 * Added silc_client_get_server to return server entry by the
1370 server name. Affected files lib/silcclient/silcapi.h and
1373 * Redefined the IDENTIFY command in protocol specification to be
1374 more generic. It now can be used to query information about
1375 any entity in the SILC Network, including clients, servers and
1376 channels. The query may be based either the entity's name
1377 or the ID. Added support for this in both client and server.
1379 Affected files silcd/command.c and lib/silcclient/command.c
1380 and command_reply.c.
1382 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1383 the _from_client and _from_server functions. Affected file
1386 * Added silc_client_get_channel_by_id_resolve to the file
1387 lib/silcclient/silcapi.h to resolve channel information by
1388 its ID. Added also silc_client_get_channel_by_id that
1389 does not resolve it from the server.
1391 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Added SilcServerEntry context into the client library
1394 to represent one server. The INFO command now allocates
1395 these to save the resolved server info. For now on the
1396 client library will also keep information about servers,
1397 connected and resolved with INFO.
1399 The INFO command now allocates the SilcServerEntry context
1400 and saves the server info there. The COMMAND_REPLY in
1401 the INFO now returns the parameters to application in
1402 same order as defined in the protocol specification.
1404 The entries are cached in the client->server_cache.
1406 * The INFO command is now issued after received the Client ID
1407 from the server. Affected file lib/silcclient/client.c.
1409 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1410 to the application as the mode changer might be server.
1411 It is guaranteed that NULL is not returned anymore to the
1412 application. Affected file lib/silcclient/client_notify.c.
1414 The ID Type is now also passed to the application so that
1415 it can check whether the returned entry is SilcClientEntry
1418 Added new function silc_client_get_server_by_id to return
1419 the server entry by ID. Affected files are the
1420 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1422 * Do not create the channel in the Irssi SILC Client when issuing
1423 the JOIN command but when received the sucessful JOIN command
1424 reply. Otherwise the channel might get created even though we
1425 could not join it. The Affected file is
1426 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1428 * Fixed a channel joining bug in router. The router must also
1429 check the channel modes, invite and ban lists etc. when serving
1430 the JOIN command sent by normal server. Affected file is
1431 silcd/command.c. The router now resolves the client's
1432 information from the server who sent the JOIN command if it
1433 does not know it, and processes the JOIN command only after
1436 * Changed the SilcCommandCb to take new argument; void *context2.
1437 Affected file lib/silccore/silccommand.h
1439 The second argument in the command callbacks in the server now
1440 includes the SilcServerCommandReplyContext if the command was
1441 called as pending command callback from the command reply.
1442 Otherwise it is NULL. When called as pending the status of the
1443 command reply will be checked and if it was erronous the
1444 error will be sent to the original sender of the command.
1445 This way the client always receives the error messages even
1446 though the server was actually the one who received the error
1447 when it resent the command to router, for example. Affected
1448 files silcd/command[_reply].[ch].
1450 * Fixed sending WHOWAS command's error message to client if
1451 the requested client could not be found. It was missing.
1454 * Changed the CMODE and CUMODE commands reply arguments in the
1455 protocol specification. The Channel ID is now sent in both
1456 of the commands to identify the channel. Implemented this
1457 new feature to the client and server. Affected files
1458 lib/silcclient/command_reply.c and silcd/command.c.
1460 * Made better checks for invite and ban lists in the JOIN
1461 command in server. Affected file silcd/command.c.
1463 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * The server now performs the incoming host IP/DNS lookup
1466 using the silc_socket_host_lookup and thus does not block
1467 the server anymore. Affected file silcd/server.c.
1469 * Completed the multi-thread support for SILC Scheduler in
1470 the lib/silcutil/silcschedule.c.
1472 * Fixed the configure.in.pre to detect the pthread correctly
1475 * Fixed a deadlock in silc_task_queue_wakeup in the file
1476 lib/silcutil/silctask.c.
1478 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Added new function silc_schedule_wakeup that is used in
1481 multi-threaded environment to wakeup the main thread's
1482 schduler. It needs to be used when a thread adds a new task
1483 or removes a task from task queues. After waking up, the
1484 scheduler will detect the task queue changes. If threads
1485 support is not compiled in this function has no effect.
1486 Implemented the wakeup mechanism to both Unix and WIN32
1487 systems. Affected files are lib/silcutil/silcschedule.[ch],
1488 lib/silcutil/unix/silcunixschedule.c and the
1489 lib/silcutil/win32/silcwin32schedule.c.
1491 * Added new function silc_task_queue_wakeup to wakeup the
1492 scheduler by the specified task queue. Affected file
1493 lib/silcutil/silctask.[ch].
1495 * The silc_socket_host_lookup_start now wakes up the scheduler
1496 after adding the timeout task. Affected file is
1497 lib/silcutil/silcsockconn.c.
1499 * The silc_socket_host_lookup is synchronous now if the threads
1500 support is not compiled in. However, the callback is still
1501 called asyncronously through the scheduler, anyway. Affected
1502 file lib/silcutil/silcsockconn.c.
1504 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Added new function silc_socket_host_lookup to perform
1507 asynchronous IP and FQDN lookups for the socket connection.
1508 Affected files lib/silcutil/silcsockconn.[ch].
1510 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1513 that may or may not compile the mutex support in.
1515 Changed the silc_mutex_alloc interface. It allocates the
1516 mutex now to the sent pointer and returns TRUE or FALSE.
1518 Affected file lib/silcutil/silcmutex.h.
1520 * Wrote the SILC Task Queue interface to support multi-threads.
1521 Affected file lib/silcutil/silctask.[ch].
1523 * Wrote the SILC Scheduler to support multi-threads. Affected
1524 file lib/silcutil/silcschedule.c.
1526 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1529 in lib/silcutil/win32/.
1531 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Defined SILC Mutex API and SILC Thread API and implemented
1534 them for Unix. Affected files are
1535 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1536 lib/silcutil/unix/silcunixmutex.c and
1537 lib/silcutil/unix/silcunixthread.c.
1539 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Fixed the silc_server_remove_clients_by_server's channel
1542 key re-generation. The hash table handling was incorrect
1543 and would not work with many channels. Affected file is
1546 * Fixed some memory leaks around the server code.
1548 * Rewrote the silc_server_get_users_on_channel to support IPv6
1549 based Client ID's. Affected file silcd/server.c.
1551 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1552 specification. However, a separate document must be written
1553 to define the detailed signing procedure and the payload
1554 associated with the flag. Defined the flag to the
1555 lib/silccore/silcchannel.h as well.
1557 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Changed the dynamic tables to static size tables in the
1560 lib/silccrypt/silchmac.c.
1562 * Removed GCC dependencies from the code. A patch by cras.
1564 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Do not show the error "Error receiving packet bla bla"
1567 in server if it really was not an error (-2 means that reading
1568 is pending). Affected file silcd/server.c.
1570 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed a possible crash in silc_server_remove_clients_by_server
1573 in silcd/server.c. Fixed there also some memory leaks.
1575 * Fixed the silc_idlist_replace_client_id. It could replace
1576 wrong key in the hash table. Affected file silcd/idlist.c.
1578 * Do not check whether there are global users on the channel
1579 if the channel->global_users is FALSE. Affected functions
1580 silc_server_remove_from_one_channel and
1581 silc_server_remove_from_channels in silcd/server.c. Also,
1582 do not check if the removed client is local as we can be
1583 sure that global client was not removed from the channel
1584 and checking for global users is not needed.
1586 * The silc_server_remove_clients_by_server now re-generates
1587 the channel keys correctly for those channels that had
1588 clients removed from them. Affected file silcd/server.c.
1590 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Found the reason of random crashes in the server. We weren't
1593 ignoring the SIGPIPE signal (which can be sent in write())
1594 and it crashed the server. Affected file silcd/silcd.c.
1596 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Assure that sock->user_data is not NULL in the function
1599 silc_server_packet_send in silcd/packet_send.c.
1601 * Disconnect the remote connection if it could not be added
1602 to any ID lists in the server. The affected file is
1605 * Check in silc_server_packet_send[_real/dest] that the
1606 socket is not disconnecting and ignore the data if it is.
1607 Affected file silcd/packet_send.c.
1609 * Define inline to __inline on native WIN32 compilation.
1610 Affected file includes/silcwin32.h.
1612 * Added some explicit type casts for inline code since MSVC
1613 require them. Affected files lib/silcutil/silcbuffer.h,
1614 lib/trq/silcdlist.h and lib/trq/silclist.h.
1616 * Print warning in log files from now on if the packet
1617 decryption fails. Affected file silcd/server.c.
1619 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1621 * Changed the `say' client operation's interface to accept
1622 new `type' argument to indicate the type of the message sent
1623 by the library. The application may filter the library's
1624 messages according the type. The affected file is the
1625 lib/silcclient/silcapi.h.
1627 * Added two new functions to lib/silcclient/silcapi.h:
1628 silc_client_del_client and silc_client_del_client_by_id.
1629 Affected file lib/silcclient/idlist.c.
1631 * Moved the clientincludes.h from includes/ to silc/ and
1632 serverincludes.h from includes/ to silcd/.
1634 * The modes for the CMODE and CUMODE are now passed as
1635 uint32 for application with COMMAND_REPLY. The affected
1636 file is lib/silcclient/command_reply.c.
1638 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * /WHOIS without arguments shows client's own information.
1641 Affected file lib/silcclient/command.c.
1643 * Changed PING to not accept any arguments. The specs
1644 says that client can ping only the connected server so
1645 requiring an argument is not needed. Affected file is
1646 lib/silcclient/command.c.
1648 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Fixed a fatal bug in private message sending and reception
1651 encryption and decryption when using private message keys.
1652 The implementation was incorrect and did not follow the
1653 specification. It causd that some of the message were
1654 lost since it did not use the sending and receiving keys
1655 as the protocol suggests. This has been fixed and will cause
1656 incompatibilities with older clients when sending private
1657 message encrypted with private message keys. Affected files
1658 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1659 and various other in Irssi SILC Client.
1661 Added `responder' boolean argument to the functions
1662 silc_client_add_private_message_key[_ske] to indicate when
1663 the key is added as responder or initiator of the key
1666 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Removed the silc_ske_check_version function and created
1669 a SilcSKECheckVersion callback. Added also a function
1670 silc_ske_set_callbacks that is now used to set all SKE
1671 callbacks. The callback functions are not given to
1672 the SKE functions anymore, but this function is used to
1675 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1677 * Added `silc_version' argument to the silc_client_alloc
1678 to define the version of the application for the library.
1679 The library will use the version string to compare it
1680 against the remote host's (usually a server) version
1681 string. Affected file lib/silcclient/silcapi.h
1683 * Added the KE protocol context to Key Agreement context
1684 in client library so that we can abort the SKE if it
1685 is in process when we get timeout. Affected file is
1686 lib/silcclient/client_keyagr.c.
1688 * Do not resolve the client ID forever if it returns in the
1689 first time that such client does not exist. This was done
1690 for example with private message. Affected file is
1691 lib/silcclient/client_prvmsg.c.
1693 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * Do not add regex.h for WIN32. The affected file
1696 includes/silcincludes.h.
1698 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1699 not work yet 100%. It generates the DLL's automatically
1700 when compiling with --with-win32 under cygwin.
1702 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * lib/contrib/regex.c is not compiled on WIN32.
1706 * Added silc_net_get_socket_opt function to the
1707 lib/silcutil/silcnet.h.
1709 * Added includes/silcwin32.h for WIN32 specific includes
1712 * Do not use ptime structure or any of the posix process
1713 functions on WIN32 in lib/silccrypt/silrng.c.
1715 * Added silc_gettimeofday to provide generic function
1716 for struct timeval on all platforms. Added the function
1717 to lib/silcutil/silcutil.h.
1719 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1721 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1722 library as they clearly belong there. As a plus side we
1723 can make the actual socket connection routines platform
1726 Added also new generic function silc_socket_read and
1727 silc_socket_write (that used to be silc_packet_[read/write].
1728 The implementation of these are platform specific.
1730 * Added WIN32 specific routines of silc_socket_[read/write]
1731 to lib/silcutil/win32/silcwin32sockconn.c.
1733 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Added preliminary support for native WIN32 compilation under
1736 cygwin (using the -mno-cygwin option for GCC) to the
1737 ./configure.in.pre. The --with-win32 now prepares the
1738 compilation for native WIN32.
1740 * Rewrote the SILC Scheduler interface in the file
1741 lib/silcutil/silcschedule.h. The scheduler is now context
1742 based and does not have anymore any global static scheduler.
1743 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1744 and created lib/silcutil/win32 directory for WIN32 based
1747 * Added Unix specific network routines to the
1748 lib/silcutil/unix/silcunixnet.c and the old
1749 lib/silcutil/silcnet.c includes now only generic routines.
1751 Added WIN32 specific network routines to the
1752 lib/silcutil/win32/silcwin32net.c.
1754 * Added Unix specific utility functions from the
1755 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1757 * Added WIN32 SILC Scheduler to the file
1758 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1761 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Do not handle JOIN notify in the server if the target client
1764 is not registered (idata->registered == FALSE). The affected
1765 file is silcd/packet_receive.c.
1767 * Update the nickrec->founder in event_cumode in the Irssi SILC
1768 client. Affected file irssi/src/silc/core/silc-channels.c.
1770 * Fixed the CUMODE_CHANGE notify handling in the server when
1771 server and router are announcing their clients on channels.
1772 Now the mode changes are saved and notified correctly. The
1773 affected file is /silcd/packet_receive.c.
1775 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1776 They really did not replace the cache entry in the ID Cache.
1777 Now they do that. Affected file silcd/idlist.c.
1779 * Fixed the KICK notify handling in the Irssi SILC client to
1780 update the channel records so that the kicked client does not
1781 appear to be on the channel. The affected file is
1782 irssi/src/silc/core/silc-channels.c.
1784 * Always update the conn->current_channel when executing command
1785 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1787 * Fixed the KILL notify handling in Irssi SILC client to remove
1788 the killed client on all channels.
1790 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Fixed the silc_parse_command_line to remove extra spaces
1793 from the start and end of the arguments. Affected file is
1794 lib/silcutil/silcutil.c.
1796 * Cancel and free any active protocol in the function
1797 silc_server_close_connection. Affected file silcd/server.c.
1799 * Cancel and free any active protocol in the function
1800 silc_client_close_connction. Affected file is
1801 lib/silcclient/client.c.
1803 * Do not execute the KILL command for clients that are in
1804 history (ie. they are not in the network). Affected file is
1807 * Fixed KILL notify handling, client does not crash anymore.
1808 Affected file irssi/src/silc/core/silc-channels.c.
1810 * Reduced the default packet buffer size from 2048 to 1024 in
1811 lib/silccore/silcpacket.c.
1813 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1814 counter to the SKE context that is incresed when the SKE library
1815 performs async operation outside the library. If the outside
1816 process frees the SKE context and FREED status will be set
1817 and the library will detect after the sync operation that the
1818 libary is freed. The affected files are
1819 lib/silcske/silcske[_status].[ch].
1821 * Resolve the client entry information in the function
1822 silc_client_channel_message to assure that NULL pointer is not
1823 passed as client entry to the application. */
1825 * Fixed the task timeout calculation to assure that there is
1826 never negative timeouts. The affected file is
1827 lib/silcutil/silcschedule.c.
1829 * Fixed the channel user mode notification sending in server.
1830 It was sent point-to-point to the router (or to server by router)
1831 but it needs to be destined to a channel. The routines now
1832 supports sending the channel user mode notifys to the channels
1833 when announcing clients and channels. Affected files are
1834 silcd/server.c and silcd/packet_receive.c.
1836 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1837 It did not actually replace the old channel entry in the cache.
1838 Affected file lib/silcclient/client_notify.c.
1840 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1842 * Fixed a possible crash in silc_packet_send_prepare. It now
1843 assures always that there is enough space in the buffer and
1844 at the tail area of the buffer (for MAC).
1846 Fixed the inbound buffer reallocation in silc_packet_read.
1847 It was old code and did not handle the reallocation correctly.
1850 The affected file is lib/silccore/silcpacket.c.
1852 * Fixed buffer overflow in silc_parse_nickname in the file
1853 lib/silcutil/silcutil.c.
1855 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * make install generates new server keys only if there is not
1860 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1863 Added check that if the NOREPLY is set then we will not send
1864 the away message. This avoids infinite loop of away messages
1865 if both clients are away. The affected file is
1866 lib/silcclient/client_prvmsg.c.
1868 * Fixed client crash if /NICK was given without arguments.
1869 Affected file lib/silcclient/command.c.
1871 * Server does not send the invite list in INVITE command back
1872 to the client if the list was not altered. Added this notion
1873 to the protocol spec as well. Affected file silcd/command.c.
1875 Fixed possible crash in INVITE command by checking the
1876 value of silc_server_get_client_route command.
1878 * Fixed the INVITE notify type handling. The arguments are now
1879 taken in correct order and client does not crash. The affected
1880 file is irssi/src/silc/core/silc-channels.c.
1882 Removed the "Inviting xxx to channel" message from the
1883 client library away and let the application handle it.
1884 Affected file lib/silcclient/command.c. Added that message
1885 to Irssi SILC client's message formats.
1887 * Fixed CMODE command crash in client. It now checks the
1888 amount of arguments correctly and does not crash. The affected
1889 file is lib/silcclient/command.c.
1891 * Do not create new channel automatically in silc_channels_join
1892 but check whether the channel by that name already exists.
1893 Affected file irssi/silc/core/silc-channels.c.
1895 * Do not send the SERVER_SIGNOFF to router if the disconnected
1896 entity was the router. Affected file silcd/server.c.
1898 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1899 SILC client as it was missing from there.
1901 Added the handling of the KICK notify to the Irssi SILC client
1902 as it was missing. Added "you have been kicked" message to
1903 Irssi SILC client's message modules formats.
1905 Added the handing of the KILL notify to the Irssi SILC client
1906 as it was missing. Added the kill message module formats
1909 The affected file is irssi/src/silc/core/silc-channels.c.
1911 * The router did not save the channel mode the server announced.
1912 Affected file silcd/packet_receive.c.
1914 * Fixed a possible crash in INFO command in server. If the
1915 server did not provide the server info it crashed. Affected
1916 file silcd/command.c.
1918 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Fixed the GETKEY command in the server to check also the
1921 global list. Otherwise the GETKEY would not work correctly
1922 in normal SILC server. Affected file silcd/command.c.
1924 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Fixed GETKEY crash, it crashed if the command did not succseed.
1928 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1930 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1931 is now real and not just an macro interface to GMP.
1933 Removed the entire GMP from the source tree and imported new
1934 NSS MPI library instead. Reason for removing GMP is that it is
1935 extremely large and compiles extremely slow. The NSS MPI
1936 is only a few files and compiles in less than 10 seconds.
1937 The speed is also about the same as GMP. The MPI is imported
1938 to lib/silcmath/mpi.
1940 If the system has GMP installed we will still use the GMP.
1941 If it is not then the NSS MPI will be compiled.
1943 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Merged a long nickname (127 characters long) crash bugfix from
1946 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1948 * Merged a freed memory reference bugfix from Irssi CVS tree.
1949 Affected file irssi/src/core/commands.c.
1951 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Added the server's public key sving and verification to the
1954 server when performing the SKE. This was missing and the
1955 remote server's (or router's) public key was accepted without
1956 checking whether we have it previously or trust it at all.
1957 Affected file silcd/protocol.c.
1959 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Check in the silc_server_timeout_remote if protocol is active
1962 and make sure that the protocol's final callback is called so
1963 that all memory if freed. Affected file silcd/server.c.
1965 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * silc_server_whois_send_reply crashed the server if the nickname
1968 was 127 characters long. Affected file silcd/command.c.
1970 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Added sanity check to the silc_server_new_client. If the hostname
1973 is provided inside username then check that the provided hostname
1974 really is the same as the resolved one. If the hostname was not
1975 resolved then check it from the public key. Affected file is
1976 silcd/packet_receive.c.
1978 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1979 if the server disconnected us and the connection is not valid
1980 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1982 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1983 the library to the lib/silcutil/silcutil.[ch].
1985 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Close log file after open. Affected file
1988 lib/silcutil/silclog.c.
1990 * Check whether sock == NULL in silc_client_send_packet and return
1991 if it is. Affected file lib/silcclient/silcclient.c.
1993 * Check rec->entry == NULL in the Irssi SILC Client before
1994 sending the channel message. Affecte file is
1995 irssi/src/silc/core/silc-servers.c.
1997 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Merged a splitted window bugfix from Irssi CVS tree. The
2000 affected file is irssi/src/fe-text/textbuffer-view.c.
2002 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2003 It did not print nickname.
2005 * Improved the distributions system a bit.
2007 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2010 irssi/src/fe-text/gui-window.c.
2012 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2013 to in-active server. The affected file is
2014 irssi/src/silc/core/client_ops.c.
2016 * Resolve the client in USERS command reply if the entry does
2017 not have username resolved. The affected file is
2018 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2019 command to WHOIS command to really resolve stuff. The USERS
2020 is not used any more in any critical section so WHOIS can
2021 be used even though it might be slower than IDENTIFY.
2023 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2026 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * Changed the protocol API a bit more consistent in the
2029 lib/silccore/silcprotocol.[ch].
2031 * Changed the following headers to ROBODoc format:
2033 lib/silccore/silcpayload.h
2034 lib/silccore/silcprotocol.h
2035 lib/silccore/silcsockconn.h
2037 All core library headers are now formatted.
2039 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Fixed a bug in Irssi SILC client; do not show that you are
2042 server/router operator if you really are not. Affected file is
2043 irssi/src/silc/core/client_ops.c.
2045 * Renamed silc_command_free_payload to silc_command_payload_free.
2046 Affected file lib/silccore/silccommand.h
2048 * Added silcmath.h to include the prototoypes of various routines
2049 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2052 * Changed the following headers to ROBODoc format:
2054 lib/silccore/silcchannel.h
2055 lib/silccore/silccommand.h
2056 lib/silccore/silcid.h
2057 lib/silccore/silcidcache.h
2058 lib/silccore/silcmode.h
2059 lib/silccore/silcnotify.h
2060 lib/silccore/silcpacket.h
2061 lib/silcmath/silcmath.h
2063 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2065 * Added checking to the server code not to start the server if
2066 ciphers and stuff are not configured properly. Affected files
2067 silcd/serverconfig.[h] and silcd/server.c.
2069 * Changed the layout of the header files of the public interfaces
2070 in the SILC libraries. The new layout supports ROBODoc
2071 documentation tool (and some others) so that it is easy to create
2072 a library reference manual. All the other headers and source
2073 code must still follow the CodingStyle document. Also source
2074 code must not include these ROBODoc stuffs, only the headers.
2075 Furthermore, all public interface headers must now be named
2076 by using `silc' prefix, example: silcapi.h, silccipher.h.
2077 Some files were renamed due to this. All the other headers
2078 must not be used as public interfaces. I will update the
2079 CodingStyle document later. Changed following headers, so far:
2081 lib/silcclient/silcapi.h
2082 lib/silccore/silcauth.h
2083 lib/silccore/silcprivate.h
2084 lib/silccrypt/silcdh.h
2086 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Removed silc_client_packet_send_flush from the client library
2091 as it is not needed. Affected file lib/silcclient/client.[ch].
2093 * Added printing of message of unresolved authentication method
2094 to the Irssi SILC client. Added it to the module formats.
2095 Removed the same message from the client library.
2097 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Added new distribution feature, DISTLABEL. Every distribution
2100 can define own preprocessor label that can be used in the
2101 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2102 file distributions, acconfig.h.pre and prepare.
2104 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Added Makefile.defines_int to include the actual definitions
2107 for Makefile.defines.in. Tested the new distribution system,
2108 created distributions and tested installation.
2110 * Added AWAY message printing to the Irssi SILC client. Added
2111 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2113 * Added SCONNECT command to call the SILC's CONNECT command.
2114 Cannot use CONNECT directly since Irssi uses that internally.
2115 Affected file irssi/src/silc/core/silc-servers.c.
2117 Added ACTION local command. It is same as ME command but takes
2118 the channel as mandatory argument.
2120 Rewrote some of the Irssi's help files to suite for SILC
2123 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Added Makefile.defines[.in] that should for now on be included
2126 in all Makefile.am file in the source tree. That file includes
2127 all common compilation definitions for SILC source tree.
2129 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Minor changes to the ./prepare script to change the package
2132 name according the distribution name to the configure.in.
2134 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Created new distribution system. Added file `distributions'
2137 that defines all the distributions that can be created out of
2138 the SILC source tree. The ./prepare script now reads that
2139 file to determine how to prepare the distributions. The
2140 first argument to the ./prepare is the name of the distribution
2141 and second is the version of the distribution. If given
2142 without arguments it creates the default (toolkit) distribution
2143 with the default version (defined in ./prepare).
2145 All Makefile.am files that are subject to the distributions
2146 are now named as Makefile.am.pre. These are ./Makefile.am
2147 and lib/Makefile.am. Others may be changed later.
2149 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Added invite list, ban list, some key management and connection
2152 error message printing to module formats in the Irssi SILC client.
2154 * Added new silc_client_set_away_message to set the away message
2155 that is back to the person who sent private message. The
2156 affected file lib/silcclient/silcapi.h and the
2157 lib/silcclient/client_prvmsg.c.
2159 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Fixed the private message sending in the Irssi SILC client,
2162 added local command KEY to the Irssi SILC client.
2164 Added key management and key agreement message formats to the
2165 irssi/src/fe-common/silc/module-formats.[ch].
2167 Added USERS (alias WHO) printing, server/router operator
2168 indication and LIST command printing to the module formats.
2170 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Fixed channel joining notify handling, cumode notify handling
2173 from Irssi SILC client.
2175 * Added SILC specific module-formats to the Irssi SILC client so
2176 that SILC specific message hilighting, colors etc is possible.
2177 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2179 Added channel mode, channel user mode, actions, notices,
2180 whois and whowas printing to the the module-formats.c.
2182 * Fixed a bug in channel deletion in the server. The channel
2183 is not left to the cache even if the channel founder auth mode
2184 is set when there are no users anymore on the channel. Affected
2185 file silcd/server.c.
2187 * The silc_net_localhost now resolves the entire hostname including
2188 the domain name. Affected file lib/silcutil/silcnet.c.
2190 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Changed the ask_passphrase client operation to be ascynchronous.
2193 It has now a completion callback and a context that the
2194 application must call after it has got the passphrase from
2195 the user. Affected files lib/silcclient/silcapi.h,
2196 lib/silcclient/protocol.c, lib/silcclient/command.c and
2199 Added SilcAskPassphrase callback that the application calls
2200 to deliver the passphrase to the library.
2202 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2203 The public key verification and especially a certificate
2204 verification is asynchronous procedure.
2206 Added new SILC_SKE_STATUS_PENDING status to indicate the
2207 request is pending and a callback will be called to finalize
2210 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2211 indicate that remote end did not send its public key (or
2212 certificate), even though we require it. Added check for this
2213 condition in the SKE. This was a security bug, now fixed.
2215 Defined new SilcSKEVerifyCbCompletion callback that is called
2216 when the verification process is completed.
2218 The affected files lib/silcske/silcske_status.h and
2219 lib/silcske/silcske.[ch].
2221 * Changed the verify_public_key client operation to be async
2222 as well. Defined SilcVerifyPublicKey callback that is used to
2223 indicate the success of the public key verification process.
2225 Changed the server and client to use the new async client
2228 * Changed the Irssi SILC client's internal scheduler to be called
2229 twice as many times as it used to be. As a result the client
2230 should be a bit faster now. Affected file is
2231 irssi/src/silc/core/silc-core.c.
2233 * Added support to Irssi SILC client of asynchronous public key
2234 verification and passphrase inquiry. Affected file is
2235 irssi/src/silc/core/silc-core.c.
2237 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Do not say "You have left channel %s" in client library.
2240 Moved it to the application. Affected files are
2241 lib/silcclient/command.c and silc/client_ops.c.
2243 * Fixed silc_client_get_clients. Command context was not
2244 duplicated and was freed memory in the callback. Affected
2245 file lib/silcclient/idlist.c.
2247 * Do not say "you are now talking..." on JOIN command in the
2248 client library. The appliation must handle it.
2250 * Do not say ".. changed topic to" in command reply in the
2251 client libary. The application must handle it.
2253 * Fixed TOPIC command sending in the client library.
2255 * Fixed a memory leak in silc_client_command_free in the file
2256 lib/silcclient/command.c.
2258 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Imported a modified version of Irssi client to the source tree.
2261 The Irssi will be used to create a new client called
2262 Irssi SILC. Imported to irssi/.
2264 Added silc_core_init_finish function to the Irssi. Affected
2265 file irssi/configure.in.
2267 A lot changes in the Makefile.ams around the irssi tree.
2269 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Do not rehash if the new size is same as the old size of the
2272 hash table, in the silc_hash_table_rehash*. The affected file
2273 lib/silcutil/silchashtable.c.
2275 * Replaced hash_table_del_by_context calls from the server
2276 (when channel->user_list and client->channels) to the
2277 hash_table_del as it is sufficient and faster.
2279 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Added silc_hash_table_list, silc_hash_table_get and the
2282 SilcHashTableList structure to provide an alternative way to
2283 traverse the hash table. The affected files are
2284 lib/silcutil/silchashtable.[ch].
2286 * Changed the server's idlist routines to use the hash table
2287 routines to optimize the code.
2289 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Replaced the client entry's `channel' list and channel entry's
2292 `user_list' list to hash tables for optimized lookup. Changed
2293 the code to use the hash table interface around the code.
2294 Affected file lib/silcd/idlist.[ch].
2296 * Added `auto_rehash' boolean argument to the function
2297 silc_hash_table_alloc to indicate whether the hash table should
2298 auto-rehash when it thinks is appropriate time. It will
2299 increase the hash table size if the there is twice as much
2300 entries in the table than the size of the table, and will
2301 decrease the size if there are twice as less entries than
2302 the size of the table.
2304 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2308 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * silc_idcache_purge_by_context deletes the entry now by context
2311 as it is supposed to do. Affected file lib/silccore/idcache.c.
2313 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2314 client is not anymore valid (WHOWAS givens the info) and not
2315 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2317 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Removed the `data' and `data_len' arguments from the ID Cache
2320 interfaces and added `name' argument. ID Cache does not handle
2321 anymore the binary data only a names associated with given ID.
2323 * When hashing a Client ID with silc_hash_id the entire ID is
2324 not hashed anymore, instead only the hash of the Client ID is
2325 hashed. This way we can access the Client ID from the cache
2326 with Client ID but with the hash of the ID (which is a hash of
2327 the nickname) as well without any difference in performance.
2329 Added also silc_idcache_find_by_id_one_ext to do one on one
2330 searching when we have the actual ID. Added also function
2331 silc_hash_client_id_compare. The affected files are
2332 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2334 * When hashing the name associated with a ID it is always done
2335 in lowercase. This way we can access the cache without worrying
2336 about case-sensitivity, even though, for example nicknames are
2339 * Fixed a bug in server with channel message sending. It put
2340 wrong ID type as destination ID. The affected file
2341 silcd/packet_send.c.
2343 * silc_idcache_del_by_context now deletes from all hash tables
2344 by context. Affected file lib/silccore/idcache.c.
2346 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Changed the client library to use the new ID Cache interface.
2349 Changes around the source tree.
2351 * Added silc_hash_table_rehash_ext to rehash with specific
2352 hash function. Affected file lib/silcutil/silchashtable.[ch].
2354 * Added silc_hash_string_compare to compare two strings in the
2355 hash table. Affected file lib/silcutil/silcutil.[ch].
2357 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Added new function silc_idcache_del_by_context into the
2360 lib/silccore/idcache.[ch].
2362 * Changed the server's ID list routines to use the new ID Cache
2363 interface. Changes around the source tree.
2365 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Added silc_hash_table_del[_by_context]_ext functions in to the
2368 lib/silcutil/silchashtable.[ch].
2370 Removed silc_hash_table_find_all* routines and added new
2371 silc_hash_table_find_foreach to replace them.
2373 Added silc_hash_table_replace_ext function as extended
2374 replacing function. Separated the simple hash table interface
2375 from the extended hash table interface in the file
2376 lib/silcutil/silchashtable.h.
2378 * Fixed minor bugs and changed it to use some of the new
2379 hash table functions in lib/silccore/idcache.c
2381 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * Added new function silc_hash_table_find_all to return all keys
2384 in the hash table by the specified key. As the hash table is
2385 collision resistant it also makes it possible to have several
2386 duplicate keys in the hash table. This function may be used to
2387 find all of the keys from the hash.
2389 Added user_context arguments to the SilcHashFunction,
2390 SilcHashCompare and SilcHashDestructor to deliver user specified
2393 Added new fuctions silc_hash_table_find[_all]_ext to do
2394 extended lookup with specified hash and compare functions and
2395 specified user contexts.
2397 Added new function silc_hash_table_add_ext to add the key
2398 with specified hash function and user context.
2400 Added new function silc_hash_table_foreach to traverse all
2401 entrys in the hash table. Added SilcHashForeach callback
2404 Added new function silc_hash_table_del_by_context to delete
2405 the entry only if the context associated with the key matches.
2407 Affected files are lib/silcutil/silchashtable.[ch].
2409 * Removed silc_hash_[server/client/channel]_id and added just
2410 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2411 silc_hash_id_compare to compare two ID's using as the hash table
2412 comparison function. Added also silc_hash_data to hash
2413 binary data and silc_hash_data_compare to compare it.
2415 * Removed silc_idlist_find_client_by_hash as it is not needed
2416 anymore. Affected file silcd/idlist.[ch].
2418 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2419 to use internally the SilcHashTable. The new ID Cache is a lot
2420 faster than the old one. Some of the ID Cache interface was also
2421 rewritten and obsolete and stupid functions were removed.
2423 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Added entry_count field to the SilcHashTable to keep the number
2426 of the entries in the table. Implemented the function
2427 silc_hash_table_rehash. Added new function
2428 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2430 Fixed a minor bug in silc_hash_table_free.
2432 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2433 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2434 into the lib/silcutil/silcutil.[ch].
2436 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Implemented a collision resistant hash table into the
2439 lib/silcutil/silchashtable[ch]. See the header and the source
2440 for the SilcHashTable API.
2442 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Merged dotconf version 1.0.2 into lib/dotconf.
2446 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Do not compile anything in lib/silcsim/* if the SIM support
2449 is not enabled. The tree should now compile without problems
2452 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Compiled the SILC under cygwin. Compiled and tested briefly
2455 without problems. More tests needed. The SIMs didn't compile
2458 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2460 * Fixed possible crash in silc_get_username in the
2461 lib/silcutil/silcutil.c.
2463 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Fixed a va_arg in silc/client_ops.c.
2467 * Oops, RC5 routines were named AES and caused some problems
2468 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2470 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Added new SilcIDIP structure into the lib/silccore/id.h and
2473 replaced the old `ip' fields from all SILC ID's to that type.
2474 This is a step towards IPv6 support.
2476 The silc_id_get_len takes now the ID as an extra argument.
2477 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2478 both IPv4 and IPv6 based ID's.
2480 The affected files are lib/silccore/id.[ch] and other files
2481 around the tree using these routines.
2483 * Removed the ID length arguments in server from various
2484 silc_server_send_notify_* routines -> they are not needed
2487 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * Fixed memory leak in silc_encode_pem_file in the file
2490 lib/silcutil/silcutil.c.
2492 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Check minor version as well in the SKE. Affected files are
2495 silcd/protocol.c and lib/silcclient/protocol.c.
2497 * Added --identifier option to the server so that an identifier
2498 can be when creating the public key for the server. Affected
2499 file is silcd/silcd.c.
2501 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2502 lib/silccrypt/silcpkcs.c.
2504 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Register default ciphers and stuff when using -C option with
2507 the server. Affected file sildc/silcd.c.
2509 * Put back the servers public key filename format, it is better
2510 than the new one. For now, the client keys are saved with the
2511 new filename format. The affected file silc/client_ops.c.
2513 * Implemented the Cipher API for the rest of the ciphers that
2514 did not implement it or implemented it the wrong way.
2516 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Register default ciphers and stuff when using the -S option
2519 in the client. Affected file silc/silc.c. Same also when
2520 creating new key pair with -C option.
2522 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Fixed the silc_verify_public_key client operation function to
2525 save the public keys differently. The fingerprint is now
2526 used as filename and not the hostname. This way also the
2527 client keys are saved uniquely and not with hostnames. The
2528 affected file is silc/client_ops.c.
2530 * Trimmed the silc_hash_fingerprint function to remove extra
2531 whitespaces from the end of the fingerprint. The affected
2532 file is lib/silccrypt/silchash.c.
2536 * Added silc_cipher_register_default function to register all
2537 default ciphers. It can be used when configuration files
2538 does not exist and the application does not want any specific
2539 ciphers in any specific order.
2541 The SilcDList is now used as silc_cipher_list dynamically
2542 allocated cipher list. Removed the static list all together
2543 and now all ciphers must be allocated to the dynamic list.
2544 The silc_cipher_alloc routine was changed to check only the
2547 All silc_cipher_* routines that used to return int returns
2550 The affected files lib/silccrypt/silccrypt.[ch].
2552 * The same thing was done to silc_hash_* as for silc_cipher_*
2553 routines. Affected files lib/silccrypt/silchash.[ch].
2555 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2556 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2557 Added also silc_pkcs_[un]register[_default] functions.
2558 Removed the data_context from the PKCS API.
2560 * Added silc_hmac_register_default function to register default
2561 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2562 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2563 to unregister all hmacs at once.
2565 * Register the default ciphers, hash functions, PKCSs and HMACs
2566 if client's configuration file does not exist. The affected
2569 * The client did not load the hash functions from the SIM
2570 modules at all. Added support for this. Affected file is
2571 silc/clientconfig.c.
2573 * When decoding public key with silc_pkcs_public_key_decode, check
2574 the supported algorithm only if PKCS are registered. Affected
2575 file lib/silccrypt/silcpkcs.c. The same was done with the
2576 silc_pkcs_private_key_decode.
2578 * Fixed the SILC List routines to keep the list always in order.
2579 It used to change the list's order when traversing the list but
2580 not it preserves the order. Affected file lib/trq/silclist.h.
2582 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Added the client library to use the SilcSocketConnection's
2585 reference counter (by silc_socket_dup) to prevent the bug that
2586 the socket object may be freed underneath async operation.
2588 * The name resolv library checking fixes in the configure.in.pre.
2591 * Created new version of the protocol drafts for future
2592 development. The -03 drafts are the ones that will be changed
2593 in the trunk now and the -02 will remain as they are.
2595 * Send list of CUMODE notifys to the router when announcing
2596 the channel users to the router. Affected file silcd/server.c.
2597 If the router receiving channel founder CUMODE for a channel
2598 that already has channel founder it will send CUMODE notify
2599 to the sender to remove the channel founder rights from the
2600 announced client. Affected file silcd/packet_receive.c.
2602 * The CUMODE notify may now use Server ID as well as the entity
2603 who changes the mode. Updated protocool specs.
2605 * Updated INSTALL and README files.
2607 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * New web pages in the http://silc.pspt.fi. The pages was
2614 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Implemented the [DenyConnectin] config section in the server.
2617 Added silc_server_config_denied_conn to check whether incoming
2618 connection is denied. Affected file silcd/serverconfig.[ch].
2620 * Do not check the ports when checking the incoming configuration
2621 data if the port is 0, meaning any. Affected file is
2622 silcd/serverconfig.c.
2624 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Fixed buffer overflow in silc_string_compare in the file
2627 lib/silcutil/silcutil.c.
2629 * Fixed double free in silc_server_command_leave in the file
2632 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Fixed the version checking in the server. Affected file is
2637 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Fixed the configuration data fetching when accepting new
2640 connections in the server. Affected file silcd/server.c.
2642 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added `sender_entry' argument to the function
2645 silc_server_packet_relay_to_channel so that we can check
2646 whether some destination actually belongs to the same route
2647 the sender belongs (ie, we must not resend the packet to the
2648 sender). Affected file silcd/packet_send.[ch].
2650 * Added `servername' field to the SilcClientEntry in the server
2651 to hold the name of the server where client is from. Affected
2652 file is silcd/idlist.h.
2654 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Moved the channel message encrypting in the router betwen
2657 router connections from silc_server_channel_message to the
2658 silc_server_packet_relay_to_channel since we want to check
2659 whether we have anybody channel before encrypting anything.
2660 Affected files silcd/packet_[receive/send].c.
2662 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Fixed the [AdminConnection] server config section to support
2665 multiple entries. Affected file silcd/serverconfig.c.
2667 * Added support into the server to check the validity of the
2668 incoming connection before executing any KE or authentication
2671 * The connection configuration is now saved to the KE and
2672 connection auth protocol contexts and not fetched anymore in
2673 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2675 * The local hosts listenning address and port is also resolved
2676 now when starting the server. We want to have the socket object
2677 to include the real address and port for the listener. Added
2678 new function silc_net_check_local_by_sock into the files
2679 lib/silcutil/silcnet.[ch].
2681 * Fixed a broadcast bug in server -> do not broadcast if we
2684 * Fixed a routing bug. Do not route broadcast packets ever.
2685 Broadcast packets must be processed always and not routed since
2686 they may be destined to some other host than yourself and thus
2687 would get routed without no good reason. Affected file is
2690 * Added function silc_server_config_is_primary_route to check
2691 whether primary router connection has been configured (a router
2692 configuration that we are initiating). If there is not, we
2693 will assume that there is only two routers in the SILC network
2694 and we will use the incoming router connection as our primary
2695 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2697 * Changed the order of the broadcasting. Broadcast _after_ the
2698 packet has been processed not before. Affected file is
2701 * Fixed a [ClientConnection] parsing bug. The port was never
2702 parsed correctly thus resulting to port 0. Affected file
2703 silcd/serverconfig.c.
2705 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2706 argument and did not set the broadcast packet flag. Affected
2707 file silcd/packet_send.c. Fixed same bug in the function
2708 silc_server_send_notify as well.
2710 * If we receive NEW_ID packet for our own ID in the server, ignore
2713 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Removed the nickname from the Private Message Payload.
2718 Updated the code and the protocol specs.
2720 * Updated protocol specs for submitting to the IETF.
2722 * Tweaked the Random Number Generator a bit. Affected file
2723 lib/silccrypt/silcrng.c. Exported a new function
2724 silc_rng_[global]_add_noise which can be used to add more
2727 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Do not parse packets with different timeout when protocol
2730 is active -> may cause problem with rekey. Affected file
2733 * When server receives signoff notify it must not create
2734 new channel key if the client is on any channels since the
2735 sender of the signoff notify will create it.
2737 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added printing of error messages during SKE protocol from the
2740 failure packet sent by server during SKE. Affected file
2743 * Removed the client's failure_callback handling with timeout
2744 and handle it immediately when received.
2746 * The SKE library returned wrong type in SUCCESS and FAILURE
2747 packets. They must be 32 bit MSB not 16 bit MSB.
2749 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * Ok, rewrote the logic of the re-key and now it seems to work.
2752 I tested it on high traffic with frequent re-keys without
2753 problems. Added hmac_receive (and renamed hmac to hmac_send)
2754 in SilcClientConnection in lib/silcclient/client.h and
2755 in SilcIDListData in silcd/idlist.h. Also, removed the
2756 SilcPacketParserContext's cipher and hmac fields as they are
2757 not needed anymore and actually caused some problems when
2758 the ciphers and hmac's changed underneath the packet parser.
2760 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * If re-key protocol is active then process the incoming packets
2763 synchronously since we must assure that icoming packets encrypted
2764 with the old key is processed before the new keys is set to
2765 use. This is true other packets than for REKEY packets.
2766 Affected file silcd/server.c. The same was done to client library
2767 as well, affected file lib/silcclient/client.c.
2769 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Fixed bug in client and server to accept the force send if
2772 the packet is send from silc_[server/client]_packet_process
2773 function. Otherwise the packets are never delivered, oops.
2775 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Disable force sending of packets when REKEY protocol is active.
2778 We must assure that no packet is sent directly when rekey is
2779 performed. All packets must be sent through packet queue.
2780 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2781 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2782 function is silc_[server/client]_packet_send_real to check
2785 * Replaced the SIM paths from example config files to
2786 /usr/local/modules. Also, make install creates now
2787 /usr/local/silc/logs directory to hold all the SILC server
2790 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Made the configure.in.pre work on Solaris. Patch by salo.
2794 * Made all ciphers compatible with non-x86 machines. Defined
2795 CBC mode macros into lib/silccrypt/ciphers_def.h.
2797 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Fixed the make install.
2801 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * When MAC computation fails the silc_packet_decrypt returned 0
2804 even though it was supposed to return -1. Fixed this. The
2805 affected file is lib/silccore/silcpacket.c.
2807 * Do not replace the config files in /etc/silc (in make install)
2808 if they already exist. Affected file ./Makefile.am.
2810 * Do not send re-key packets immediately but through packet queue.
2811 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2813 * Changed silc_net_check_host_by_sock to return FALSE if the
2814 IP/DNS could not be resolved. Though, it returns the IP address
2815 now even if it could not resolve it (but returns also FALSE).
2816 Affected file lib/silcutil/silcnet.[ch].
2818 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2820 * Added silc_pkcs_decode_identifier to decode the public key's
2821 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2822 Added also silc_pkcs_free_identifier. Added also new context
2823 SilcPublicKeyIdentifier.
2825 * Added -S option to the silc client. It is used to dump the
2826 contents of the specified public key file.
2828 * Changed the PKCS api to return the public key length when
2829 setting the public key.
2831 * Fixed a fatal bug in the public and private key file loading.
2832 Affected file lib/silccrypt/silcpkcs.c.
2834 * Execute the packet parsing for client with zero (0) timeout
2835 if the protocol is active. Affected file silcd/server.c.
2837 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Made the key generation options to the silcd program. Added
2840 -C option, equivalent to client's option.
2842 * Added new [ServerKeys] config section to the server. It
2843 configures the server's public and private key.
2845 * Defined generic Public Key Payload into the protocol
2846 specification to send specific type of public keys and
2849 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2850 public key or certificate.
2852 * Implemented the GETKEY command to the server and to the
2853 client library and on user interface.
2855 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Made preliminary `make install' work.
2859 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Added SilcServerRekey context into silcd/idlist.h.
2863 * Added the PFS support as defined in the specification to the
2864 SKE protocol. Affected files lib/silcske/*.c.
2866 * Added `ske_group' field to the SilcServerRekey context to hold
2867 the number of the SKE group that is used with PFS in re-key.
2868 Affected file silcd/idlist.h.
2870 * Added PFS re-key support to the server. Affected file is
2873 * Added silc_protocol_cancel to cancel execution of the next
2874 state of the protocol. Affected file is
2875 lib/silccore/silcprotocol.[ch].
2877 * Added the re-key support with and without PFS to the client
2878 library. Re-key is performed once in an hour, by default.
2880 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2881 Added silc_client_rekey_callback and silc_client_rekey_final.
2882 Affected files are lib/silcclient/protocol.[ch] and
2883 lib/silcclient/client.[ch].
2885 * Removed the `hmac_key' and `hmac_key_len' fields from the
2886 SilcClientConnection structure; not needed. Affected file is
2887 lib/silcclient/client.h.
2891 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Do not ask whether user wants to use the negotiated private key
2894 for private messages, just use it. Affected file is
2895 silc/local_command.c.
2897 * Added `send_enc_key' and `enc_key_len' fields to the
2898 SilcIDListData structure since they are needed in the re-key
2899 phase. Affected file is silcd/idlist.[ch].
2901 * Implemented the simple re-key protocol into the server.
2902 Affected files silcd/server.c and silcd/protocol.[ch]. The
2903 re-key will be performed once in an hour, by default.
2905 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2906 Added silc_server_rekey, silc_server_rekey_callback and
2907 silc_server_rekey_final.
2909 * Removed Tunneled flag from the protocol. Updated the code
2910 and the specifications.
2912 * Adde `pfs' field to the SilcIDListData to indicate whether
2913 the PFS is to be performed in the re-key. Affected file is
2916 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2918 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2919 int64 of at least the xintXX size. If void * is less that 4
2920 bytes uint32 * will be used. Defined bool as boolean.
2922 * Changed _ALL_ unsigned long and unsigned int to uint32,
2923 unsgined short to uint16 in the source tree.
2925 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2926 not handle clients that has entry->data.registered == FALSE.
2927 They are not in the network anymore. Affected file is
2930 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Implemented the sending of the SERVER_SIGNOFF notify in the
2933 server. Affected file is silcd/server.c.
2935 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2936 Added also silc_notify_payload_encode_args into the
2937 lib/silccore/silcnotify.[ch].
2939 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2940 Affected file silcd/packet_receive.c.
2942 * Implemented the SERVER_SIGNOFF notify handling in the client
2943 library. Affected file lib/silcclient/client_notify.c. Also,
2944 implemnted the printing of the SERVER_SIGNOFF info to the
2945 application. Affected file silc/client_ops.c.
2947 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2948 if the deleting was successful. Affected file silcd/idlist.[ch].
2950 * Added support for public key authentication in the connection
2951 authentication protocol in the client library. Affected file
2952 lib/silcclient/protocol.c.
2954 * Changed the server's silc_idlist_get_clients_by_* interface
2955 to support already allocated array so that new entries may be
2956 added to pre-allocated array. Affected file silcd/idlist.[ch].
2957 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2958 and command replies.
2960 * All command reply functions in the server now calls the
2961 pending command callback even if error occured. This way the
2962 error will be delivered to the client as well. Affected files
2963 silcd/command.c and silcd/command_reply.c.
2965 * Fixed INFO command to return local server's info if no server
2966 was provided. Affected file lib/silcclient/command.c.
2968 * Removed RESTART command for good. Updated the code and the
2971 * Rewrote parts of the task system. It is a bit simpler now.
2972 Removed unsued task priorities. The affected files are
2973 lib/silcutil/silctask.[ch].
2975 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Moved the USERS printing from the library to the application.
2978 Affected files lib/silcclient/command.c and silc/client_ops.c.
2980 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Added channel key re-key support. The re-key is perfomed
2985 only by the router and is done once in an hour. Added `rekey'
2986 field to the SilcChannelEntry in the server. Affected files
2987 silcd/server.c and silcd/idlist.h.
2989 * Added silc_task_unregister_by_context into the file
2990 lib/silcutil/silctask.[ch].
2992 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Added SILC_UMODE_GONE mode to indicate when the client is not
2995 present in the SILC network. Added also support to the local
2996 command AWAY that will set this mode. Added support of showing
2997 "xxx is gone" in WHOIS command. The USERS command shows the
2998 gone status as well.
3000 * Fixed setting server and router operator privileges in the
3001 server's UMODE command. Affected file silcd/command.c.
3003 * Merged the SKE KE1 and KE2 payloads into one payload. The
3004 new KE payload is equivalent to the old KE2 payload.
3006 Cleaned up the SKE Start Payload parsing. It now uses the
3007 simple buffer unformatting to do the parsing. A lot faster
3010 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3011 to the SKE that is used to indicate whether both of the SKE
3012 parties should perform authentication. By default only the
3013 responder performs authentication. By setting this flag also
3014 the initiator must do authentication. By default it is unset
3015 since in normal SKE case, client to server connection, only
3016 the responder should do authentication. When doing SKE between
3017 two clients both should perform authentication. Updated the
3018 code and the protocol specs.
3020 * A little fix to IDENTIFY command in the server. Search the
3021 client first by hash not nickname. Affected file is
3024 * Fixed the silc_client_close_connection to support closing
3025 the client to client connections wihtout deleting too much
3026 data. Affected file lib/silcclient/client.c.
3028 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3029 are received if protocol used to be active but is not anymore
3030 the application would crash due to NULL pointer dereference.
3031 Affected files silcd/server.c and lib/silcclient/client.c.
3033 * Added `hash' field to the SilcClientConnection to include
3034 the hash function negotiated in the SKE protocol.
3036 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3037 to set the channel founder authentication data. A client can
3038 claim the founder rights later by providing the authentication
3039 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3040 This way the channel founder can regain the channel founder
3041 privileges even it is left the channel. This works only on
3042 local server and the client must be connected to the same
3043 server to be able to regain the founder rights. Updated the
3044 protocol specs accordingly.
3046 Added support to the CMODE command in the client to set the
3047 founder auth data. Read the README to see how to set it.
3049 Added support to the CUMODE command to claim the founder
3050 rights. Read the README to see how to do it.
3052 Added support for the founder authentication to the Channel
3053 Entry in the server. Affected file silcd/idlist.h.
3055 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3056 server's CMODE command. Affected file silcd/command.c.
3058 * Added the following new functions into lib/silccore/silcauth.[ch]:
3059 silc_auth_get_method and silc_auth_get_data.
3061 * The server now saves the remote hosts public key to the
3062 SilcIDListData pointer. Affected file silcd/protocol.c.
3064 * The normal server now does not remove the channel entry from
3065 the cache if the founder authentication data is set. It used
3066 to remove it if the founder was the last one on the channel on
3067 the server and left the channel. The auth data is saved and
3068 if the channel is re-joined later the old entry is used with
3069 the old auth data. Affected files silcd/command_reply.c and
3072 * Removed the `pkcs' field from the SilcIDListData structure
3073 in the server; it is not used. Affected file silcd/idlist.h.
3075 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Fixed packet processing on slow links. Partial packets were
3078 never re-processed because the incoming data buffer was cleared
3079 by the application. Application must not directly clear the
3080 sock->inbuf, the packet processing routines handle it. Fixed
3081 this in client library and in server.
3083 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Fixed the WHOIS and IDENTIFY send reply function to really
3086 check whether to send list or just one entry. Affected file
3089 * Cleaned up the LEAVE command's channel key distribution. The
3090 affected file silcd/command.c.
3092 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3093 can enforce the channel mode as well. In that case the ID
3094 includes the ID of the server. The code now enforces the
3095 mode change if the router have different mode than the server.
3097 * The notify client operation with CMODE_CHANGE notify can now
3098 return NULL client_entry pointer if the CMODE was not changed
3099 by client. Application must check for this.
3101 * Added <Server ID> argument to INFO command to support server
3102 info fetching by Server ID.
3104 * Added silc_server_announce_get_channel_users to get assembled
3105 packets of channel users of the specified channel. Affected
3106 file silcd/server.[ch].
3108 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3109 was freed underneath the ID Cache.
3111 * Re-announce clients when the server received CHANNEL_CHANGE
3112 notify from the router. Affected file silcd/packet_send.c.
3114 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3117 crashed since it did not handle the fact that there is no cipher
3118 called "3" and didn't check the error condition. Now fixed.
3120 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3121 flag. It can be used to send message requests.
3123 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Implemented the RESTART command in the client.
3127 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3128 notice type messages. Added notice printing to the user
3131 * The channel keys are not re-generated if the channel's mode
3132 is PRIVKEY, ie private key on the channel exists. Affected
3133 files silcd/server.c and silcd/command.c.
3135 * Fixed a little bug in channel message delivery when channel
3136 private keys are set in the server. Affected file is
3137 silcd/packet_send.c.
3139 * Changed the setting on channel->on_channel = TRUE from the
3140 silc_client_save_channel_key to the JOIN command reply. The
3141 key payload is not received if the private channel key is set.
3142 Affected file lib/silcclient/command_reply.c and the
3143 lib/silcclient/client_channel.c.
3145 * When the CMODE_CHANGE notify is sent and the channel private
3146 key mode is removed the channel key must be re-generated in
3147 other cells as well. Added this support for the router in the
3148 silcd/packet_receive.c.
3150 * Added new local command NOTICE to send notice message on
3151 channel. Affected file silc/local_command.[ch].
3153 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Added new local command ME to the client. It is used to send
3156 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3157 some action. Affected file silc/local_command.[ch].
3159 * Changed channel_message and private_message client operations
3160 to deliver the message flags to the application. Added also
3161 the `flags' arguments to the silc_client_send_channel_message
3162 and silc_client_send_private_message functions. Affected file
3165 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Redefined the Private Message Payload to support private message
3168 keys and to support the new private message flags. Updated
3169 the protocol specs. Flags makes it possible to have for example
3170 CTCP style messages.
3172 * Added new type SilcPrivateMessagePayload and defined an API
3173 for it in the lib/silcclient/silcprivate.[ch].
3175 * Tested private message private keys successfully. Tested the
3176 private message key set, unset and list commands with the new
3179 * Redefined the Channel Message Payload to include the channel
3180 message flags (equal with private message flags) to support
3181 for example CTCP style messages.
3183 * Defined some of the message (for channel and private message)
3184 flags. Updated the protocol specs and added the flags to the
3185 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3187 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Added SilcKeyAgreementStatus type to the key agreement routines
3190 to indicate the current status and error if one occured.
3191 The status types are defined in the lib/silcclient/silcapi.h.
3193 * Added new local command KEY that is used to set and unset private
3194 keys for channels, set and unset private keys for private messages
3195 with remote clients and to send key agreement requests and
3196 negotiate the key agreement protocol with remote client. The
3197 key agreement is supported only to negotiate private message keys,
3198 it currently cannot be used to negotiate private keys for channels,
3199 as it is not convenient for that purpose.
3201 * Fixed a minor pending callback setting bug in the function
3202 silc_client_get_client_by_id_resolve, now the function works.
3203 Affected file lib/silcclient/idlist.c.
3205 * Added function silc_net_get_local_port to get local bound
3206 port by socket. Added to lib/silcutil/silcnet.[ch].
3208 * Added `sockets' and `sockets_count' fields to the SilcClient
3209 object. They hold the sockets of the listenning sockets in
3210 the client. Listenning sockets may be for example the key
3211 agreement server. Affected file lib/silcclient/client.[ch].
3212 Added functions the silc_client_add_socket and the
3213 silc_client_del_socket. They are exported to the application
3216 * Added ~./silc/clientkeys to support other client's public keys.
3218 * Renamed verify_server_key client operation to verify_public_key
3219 and added one argument to indicate the type of the connection
3220 (server, client etc.).
3222 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added silc_server_connection_auth_request to handle the
3225 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3226 silcd/packet_receive.[ch].
3228 * Added silc_server_send_connection_auth_request into the
3229 silcd/packet_send.c to send the connection auth request packet.
3231 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3234 * Fixed the public key authentication in responder side in the
3235 server. The `auth_data' pointer includes the SilcPublicKey
3236 not the path to the public key. Affected file silcd/protocol.c.
3238 * Implemented the public key authentication in the initiator side
3239 in the server. Affected file silcd/protocol.c.
3241 * Removed the [RedirectClient] config section from the server
3242 configuration. Is not needed and I don't want to implement it.
3244 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Cleaned up the CMODE command in the server. It now works
3247 correctly and supports all the modes defined in the protocol.
3248 Affected file is silcd/command.c.
3250 * Added `hmac_name' field to the SilcChannelEntry in the server
3251 to hold the default HMAC of the channel. It can be set when
3252 creating the channel (with JOIN command). Affected files
3255 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3256 type to indicate the change of the current cipher and hmac
3257 on the channel. Client can safely ignore the <cipher> argument
3258 (if it chooses to do so) since the CHANNEL_KEY packet will
3259 force the channel key change anyway. The <hmac> argument is
3260 important since the client is responsible of setting the new
3261 HMAC and the hmac key into use.
3263 * Fixed the CMODE command in the client library as well.
3265 * Tested CMODE command in router environment successfully.
3267 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Show the version of the remote client (or server) when connecting
3270 to the server. It is logged to the log file. Affected file
3271 is silcd/protocol.c.
3273 * Fixed the KILLED notify handling in the client library. The
3274 client must be removed from all channels when receiving the
3277 Also, do not remove the client entry when giving the KILL
3278 command but when the KILLED notify is received.
3280 * Removed silc_idlist_find_client_by_nickname from the server.
3281 Not needed anymore. Affected files silcd/idlist.[ch].
3283 * Implemented the CHANNEL_CHANGE notify type handling to the
3284 server. Affected file silcd/server.c.
3288 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Added silc_server_send_notify_invite to send the INVITE
3291 notify between routers.
3293 * Implemented the INVITE command correctly to the server.
3295 * Implemented the INVITE notify type handling in the server.
3297 * Implemented the INVITE command to the client library and on the
3300 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added function silc_server_get_client_resolve to find the
3303 client entry by ID from all ID lists and then resolve it
3304 (using WHOIS) if it cannot be found. Affected file is
3307 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Implemented the BAN command to the client library.
3311 * The JOIN command in the server now checks the invite list
3314 * Changed the silc_command_reply_payload_encode_va and the
3315 silc_command_payload_encode_va to support that if argument is
3316 NULL it ignores and checks the next argument. Affected file
3317 lib/silccore/silccommand.c.
3319 * Added silc_server_send_notify_ban to send the BAN notify
3320 type between routers.
3322 * Chaned the silc_notify_payload_encode to support that if
3323 argument is NULL it ignores and checks the next argument.
3324 Affected file lib/silccore/silcnotify.c.
3326 * Tested ban lists in router environment successfully.
3328 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Implemented BAN command to the server, in silcd/command.[ch].
3332 * Removed the BAN and INVITE_LIST modes from the CMODE command
3335 * Added function silc_string_match to regex match two strings.
3336 Affected files lib/silcutil/silcutil.[ch].
3338 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Redefined parts of the SilcChannelEntry in the server to support
3341 the new ban and invite lists.
3343 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Redefined the INVITE command. The same command can be used to
3346 invite individuals to the channel but also to manage the invite
3347 list of the channel (to add to and remove from the invite list).
3348 Updated the protocol specs.
3350 * Added new command SILC_COMMAND_BAN that can be used to manage
3351 the ban list of the channel. Updated the protocol specs.
3353 * Removed the channel modes: the SILC_CMODE_BAN and the
3354 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3355 in the CMODE command. The equivalent features are now available
3356 using INVITE and BAN commands. Updated the protocol specs.
3358 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3359 in the network about change in the current ban list. The notify
3360 type is not used by the client.
3362 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3363 support the invite lists.
3365 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Added new function silc_string_regexify that converts string
3368 including wildcard characters into regex string that can
3369 be used by the GNU regex library. Added into the file
3370 lib/silcutil/silcutil.[ch].
3372 Added silc_string_regex_combine to combine to regex strings
3373 into one so that they can be used as one regex string by
3374 the GNU regex library. Added into the file
3375 lib/silcutil/silcutil.[ch].
3377 Added silc_string_regex_match to match two strings. It returns
3378 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3380 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Imported GNU regex to the soruce tree into lib/contrib.
3383 Fixed some compiler warning from the regex.c.
3385 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Fixed MOTD command in the server to work in router environment.
3389 * Fixed the MOTD command in the client library to support
3390 the server argument in the command.
3392 * Added `nickname_len' argument to the silc_idlist_add_client
3393 in the server, as the `nickname' argument may be binary data
3396 * Added silc_idlist_get_channels to return all channels from
3399 * Implemented LIST command to the server. Affected file is
3402 * Implemented the LIST command to the client library and on the
3405 * Added [<user count>] argument to the LIST command reply.
3406 With private channels the user count is not shown.
3408 * Updated TODO and README.
3410 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * The client entry's data.registered must be TRUE even with
3413 global client entry on global client list. The data.registered
3414 is used to check whether the client is anymore in the network,
3415 for example with WHOWAS command so it must be valid.
3417 * Fixed the WHOWAS command in the server. It now actually works
3418 in router environment. Added function into silcd/command_reply.c
3419 silc_server_command_reply_whowas_save.
3421 * Added silc_idlist_purge function to the silcd/idlist.c
3422 to periodically purge the ID Cache.
3424 * Fixed INFO command in the server. It works now in router
3425 environment. Added <server name> argument to the INFO command
3426 reply. Updated the protocol specs.
3428 * Fixed minor bug in silc_idcache_purge to not purge if the
3429 expire value is zero.
3431 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3432 they were buggy because of the WHOWAS information.
3434 * Fixed local command MSG to handle the async resolving of
3435 the remote client properly. It used to fail the first MSG.
3436 Affected file silc/local_command.c.
3438 * Added `data_len' field to SilcIDCache context.
3440 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Update TODO. Todo in commands in the server.
3444 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3447 used by routers as broadcast packet to inform other routers
3448 about the changed user mode.
3450 Implemented the notify handling in the server. Affected file is
3451 silcd/packet_receive.c. Added the function
3452 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3454 * Added new generic Channel Payload and deprecated the New Channel
3455 Payload. The New Channel Payload is now the generic Channel
3458 * Added new argument `mode' to the silc_server_send_new_channel
3459 as it is required in the Channel Payload now.
3461 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3462 and created a new and real SilChannelPayload to represent the
3463 new generic Channel Payload. Implemented the encode/decode
3464 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3466 * Added silc_server_get_client_channel_list to return the list
3467 of channels the client has joined for WHOIS command reply.
3468 Affected file silcd/server.[ch].
3470 * Implemented the channel list sending in the WHOIS command reply
3471 in server and in the client.
3473 Implemented the channel list displaying on the user interface
3474 as well. Affected file silc/client_ops.c.
3476 * Added silc_channel_payload_parse_list to parse list of Channel
3477 Payloads. It returns SilcDList list of SilcChannelPayloads.
3478 Client for example can use this function to parse the list of
3479 channels it receives in the WHOIS command reply. The caller
3480 must free the list by calling silc_channel_payload_list_free.
3481 Affected files lib/silccore/silcchannel.[ch].
3483 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added one new argument <user mode> to the WHOIS command reply
3486 to return the mode of the user in SILC. Updated the protocol
3489 Implemented it to the server and client.
3491 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Fixed the mode printing on the user interface on joining.
3494 Affected file silc/client_ops.c.
3496 * Implemented the UMODE command and user modes in general to the
3497 client library and to the user interface.
3499 * Implemented the UMODE command to the server.
3501 * The server now sends UNKNOWN_COMMAND error status if client sends
3502 unknown command. Affected file silcd/command.c.
3504 * All server commands now handle the command identifier the right
3505 way when sending the command reply to the client. The client can
3506 use to identify the command replies with the identifier.
3508 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Added silc_server_get_client_route to resolve the route to
3511 the client indicated by the client ID. Affected file is
3514 * Added silc_server_relay_packet as general function to relay
3515 packet to arbitrary destination. This deprecates functions
3516 like _send_private_message_key, _relay_notify etc. Affected
3517 file is silcd/packet_send.[ch].
3519 Removed silc_server_send_key_agreement,
3520 silc_server_send_private_message_key and
3521 silc_server_packet_relay_notify functions from the file
3522 silcd/packet_send.[ch].
3526 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3527 server. Affected file silcd/packet_receive.[ch].
3529 * Implemented the KILL command to the client. Implemented the
3530 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3531 Affected files lib/silcclient/command[_reply].c and
3532 lib/silcclient/client_notify.c. Implemented the KILL notify
3533 printing in the user inteface.
3535 * Fixed a lot silc_parse_nick memory leaks from the client
3536 library in the file lib/silcclient/command.c.
3538 * Changed the silc_server_send_notify_on_channels's `sender'
3539 argument from SilcSocketConnection to SilcClientEntry to
3540 check the sender as entry and not as connection object and not
3541 to send to the client provided as argument. The affected file
3542 is silcd/packet_send.[ch].
3544 * The notify packets that are destined directly to the client used
3545 to not to be processed by the server. Now changed that and the
3546 server processes all notify packets. After relaying the packet
3547 to the client the notify packet is processed in the server.
3549 * The silc_server_free_client_data now checks whether there is
3550 pending outgoing traffic for the client and purges the data to
3551 the network before removing the client entry.
3553 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3556 an client is killed from the SILC Network. Updated the protocol
3559 Added new function silc_server_send_notify_killed to the
3560 silcd/packet_send.[ch].
3562 * Added function silc_server_packet_relay_notify to relay notify
3563 packets that are destined directly to a client. In this case
3564 the server does not process the notify packets but merely relays
3565 it to the client. Affected file silcd/packet_send.[ch].
3567 Added also silc_server_packet_process_relay_notify to check
3568 whereto relay the notify. Affected file is
3569 silcd/packet_receive.[ch].
3571 * Implemented the KILL command to the server.
3575 * Added the backup schema desgined last fall to the protocol
3576 specs for everyone to see. The specification is in the
3577 *-spec-xx.txt draft and the packet type definitions for the
3578 backup routers is in *-pp-xx.txt draft. Thusly, added also
3579 new packet type SILC_PACKET_CELL_ROUTERS.
3581 * A big security problem in the implementation discovered. The
3582 signoff of an client did not cause new channel key generation
3583 which it of course should've done. The channel keys must be
3584 always re-generated when client leaves (or signoffs) the channel.
3585 The silc_server_remove_from_channels funtion now handles
3586 the channel key re-generation.
3588 * Added `sender' argument to the silc_server_send_notify_on_channels
3589 to not to send the client provided as argument. Affected file
3590 silcd/packet_send.[ch].
3592 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Implemented OPER and SILCOPER commands into the server and
3597 * Added silc_auth_verify and silc_auth_verify_data to verify
3598 the authentication directly from the authentication payload.
3599 It supports verifying both passphrase and public key based
3600 authentication. Affected file lib/silccore/silcauth.[ch].
3602 * Added `hash' field to the SilcIDListData structure. It is the
3603 hash negotiated in the SKE protocol. Affected file is
3606 * Slight redesigning of the SilcAuthPayload handling routines.
3607 Do not send SilcPKCS but SilcPublicKey as argument.
3609 * Implemented the public key authentication support to the
3610 serverconfig. The public key is loaded from the provided path
3611 and saved as authentication data to void * pointer. Thus,
3612 changed the unsigned char *auth_data to void *auth_data;
3614 * Fixed SHUTDOWN command to send the reply before the server
3615 is shutdown. :) Affected file silcd/command.c.
3617 * Fixed fatal bug in CONNECT command. The hostname was invalid
3618 memory and server crashed. Affected file silcd/command.c.
3620 * Fixed fatal bug in CLOSE command. The server_entry became
3621 invalid but was referenced later in the command. Affected file
3624 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Fixed fatal bug in failure packet handling. Server ignored
3627 the failure and thus crashed when it came.
3631 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3634 that the command may be executed only once in (about) 2 seconds.
3635 The old SILC_CF_LAG flag is same but allows command bursts up
3636 to five before limiting.
3638 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3639 server code. Various commands now includes the CF_LAG_STRICT
3640 flag to disallow any kind of miss-use of the command.
3642 * Fixed the silc_buffer_unformat to not to allocate any data
3643 if the length of the data is zero. It used to allocate the
3644 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3646 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Changed the format of AdminConnection configuration section
3649 in the server. Added username of the admin to the format.
3650 Affected files silcd/serverconfig.[ch].
3652 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3653 to return admin configuration data by host, username and/or
3656 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Implemented WHOWAS command to the server. Added the functions:
3660 silc_server_command_whowas_parse,
3661 silc_server_command_whowas_send_reply,
3662 silc_server_command_whowas_from_client and
3663 silc_server_command_whowas_from_server
3665 * Added <Client ID> argument to the WHOWAS command reply. Updated
3666 the protocol specs accordingly.
3668 * Implemented WHOWAS command and command_reply to the client
3671 Implemented the WHOWAS printing on the user interface.
3673 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Added new argument to the WHOWAS command reply, the real name.
3676 It is an optional argument. Updated the protocol specs.
3678 * Added SilcIDCacheDestructor callback that is registered when
3679 the SilcIDCache is allocated. The callback is called when
3680 an cache entry in the ID Cache expires, or is purged from the
3681 cache. Added into lib/silccore/idcache.[ch].
3683 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3684 to destruct the client entries when the cache entry expires.
3685 Other ID Cache's in server and in the client library ignores
3688 * If the ID Cache entry's `expire' field is zero then the entry
3689 never expires. Added boolean `expire' argument to the
3690 silc_idcache_add function in the lib/silccore/idcache.[ch].
3691 If it is TRUE the default expiry value is used.
3693 * Added silc_server_free_client_data_timeout that is registered
3694 when client disconnects. By default for 5 minutes we preserve
3695 the client entry for history - for WHOWAS command.
3697 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Added support to the server to enforce that commands are not
3700 executed more than once in 2 seconds. If server receives
3701 commands from client more frequently, timeout is registered
3702 to process the commands. Affected file silcd/command.c.
3703 Added new function silc_server_command_process_timeout.
3705 * Changed NICK_NOTIFY handling in client library to check that
3706 if the client's nickname was changed, so there is no need to
3707 resolve anything from the server.
3709 * Removed error printing from the WHOIS and IDENTIFY commands.
3710 If error occurs then it is ignored silently in the client library.
3711 The application, however, may map the received error to
3712 human readable error string. The application currently maps
3713 the NO_SUCH_NICKNAME error to string.
3715 * Made the command status message public to the application. Moved
3716 them from lib/silcclient/command_reply.c to
3717 lib/silcclient/command_reply.h. The application can map the
3718 received command status to the string with the
3719 silc_client_command_status_message function.
3721 * Added check to the server to check that client's ID is same
3722 as the Source ID in the packet the client sent. They must
3725 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Added dist-bzip hook to the Makefile.am to make bzip2
3728 compressed distributions.
3730 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Server now enforces the maximum length for the nickname and
3733 the channel as protocol specification dictates. 128 bytes for
3734 nickname and 256 bytes for channel name.
3736 * Moved the WHOIS printing to the application. The client libary
3737 does not print out the WHOIS information anymore, the application
3738 must do it. Renamed silc_client_command_reply_whois_print to
3739 the silc_client_command_reply_whois_save.
3741 The client's idle time is also sent to the application now, and
3742 the idle is shown on screen.
3744 * Added silc_client_command_reply_identify_save to save the
3745 received IDENTIFY entries.
3747 * Do not check for channel private keys in message sending and
3748 reception if the channel does not have the PRIVKEY mode set.
3749 Affected file lib/silclient/client_channel.c.
3751 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3754 just surfaced after chaning the JOIN procedure.
3756 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Added silc_client_get_clients_by_list to get client entries
3759 from Client ID list, that is returned for example by JOIN
3760 and USERS command replies. The application should use this
3761 function for example when JOIN command reply is received to
3762 resolve the clients already on the channel (library does not
3763 do that anymore as USERS command reply is not used in the JOIN
3764 procedure anymore). Affected files lib/silcclient/silcapi.h and
3765 lib/silcclient/idlist.c.
3767 * JOIN command reply and USERS command reply returns now SilcBuffer
3768 pointers instead of unsigned char pointers when returning
3769 the client list and mode list.
3771 * Added <Client ID> argument to the JOIN command reply, mainly
3772 for the server to identify for which client the command was
3773 originally sent. Updated protocol specs accordingly.
3775 * Added SilcDlist private_key pointer to the SilcChannelEntry
3776 in the client to support the channel private keys. Affected
3777 file is lib/silcclient/idlist.h.
3779 * Added SilcChannelPrivateKey argument to the function
3780 silc_client_send_channel_message so that application can choose
3781 to use specific private ke if it wants to. If it is not provided,
3782 the normal channel key is used, unless private keys are set.
3783 In this case the first (key that was added first) is used
3784 as the encryption key.
3786 * Implemented the support for channel private key handling.
3787 Implemented the following functions:
3789 silc_client_add_channel_private_key,
3790 silc_client_del_channel_private_keys,
3791 silc_client_del_channel_private_key,
3792 silc_client_list_channel_private_keys and
3793 silc_client_free_channel_private_keys
3795 Affected file lib/silcclient/client_channel.c.
3797 * Added the support for the private keys in the channel message
3798 sending and encryption and in the message reception and
3799 decryption. Affected funtions are
3800 silc_client_send_channel_message and silc_client_channel_message.
3802 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Added SKE's key verify callback to the client library's
3805 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3807 * Removed the statement that server (or router) must send USERS
3808 command reply when joining to the channel so that the client
3809 knows who are on the channel. Instead, the client list and
3810 client's mode list is now sent in the JOIN command reply to the
3811 client who joined channel. This is better solution.
3813 * Added function silc_server_get_users_on_channel and function
3814 silc_server_save_users_on_channel to the silcd/server.[ch].
3816 * Removed function silc_server_command_send_users from the
3819 * Do not show topic on the client library anymore. The topic is
3820 sent in the command reply notify to the application and the
3821 application must show the topic now.
3823 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Added client searching by nickname hash into the IDENTIFY and
3826 WHOIS commands in the server as they were clearly missing from
3827 them. Affected file is silcd/command.c.
3829 * Fixed a bug in private message receiving in the client library.
3830 The remote ID was freed and it wasn't supposed, now it is
3833 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * Minor fix to the channel payload; allocate the data area, as it
3836 needs to be of specific length.
3838 * If the key agreement port is zero then the operating
3839 system will define the bound port. Affected files are
3840 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3842 * Added new function silc_channel_payload_decrypt into the file
3843 lib/silccore/silcchannel.[ch].
3845 * Moved the channel message etc, check from silc_packet_decrypt
3846 to applications. The library calls now a generic
3847 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3848 when the packet is either normal or special. This was done to
3849 allow more wide range of checking that was not allowed when
3850 the code was in library. Now applications can do virtually any
3851 checks to the packet and return to the library the decision how
3852 the packet should be processed. Affected files are
3853 lib/silccore/silcpacket.[ch].
3855 Added silc_server_packet_decrypt_check to the server and
3856 silc_client_packet_decrypt_check to the client library.
3858 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3859 to send with specified source and destination information.
3861 * Channel message delivery between routers was broken after the
3862 channel key distribution was fixed earlier. The channel key
3863 was used be to distributed to other routers as well which is not
3864 allowed by the protocol. Now this is fixed and channel keys
3865 really are cell specific and the channel message delivery between
3866 routers comply with the protocol specification.
3868 * Fixed various commands in server to check also the global list
3869 for the channel entry and not just the local list. The affected
3870 file silcd/command.c.
3872 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Added assert()s to buffer formatting and unformatting routines
3875 to assert (if --enable-debug) when error occurs. Affected
3876 file: lib/silcutil/silcbuffmt.c.
3878 * Changed to auto-reconnect to check whether the remote host is
3879 router and register the re-connect timeout if it is. It used
3880 to check that whether we are normal server, but router must do
3881 auto-reconnect with another router as well. Affected file
3884 * Removed the [<key len>] option from CMODE command as the cipher
3885 name decides the key length, nowadays. See the defined ciphers
3886 from the protocol specification.
3888 * Added [<hmac>] option to the CMODE command to define the HMAC
3889 for the channel. Added SILC_CMODE_HMAC channel mode.
3891 * Added [<hmac>] option for the JOIN command so that user can
3892 select which HMAC is used to compute the MACs of the channel
3895 * Added Hmac field to the Channel Message Payload. The integrity
3896 of plaintext channel messages are now protected by computing
3897 MAC of the message and attaching the MAC to the payload. The
3898 MAC is encrypted. Now, it is clear that this causes some
3899 overhead to the size of the packet but rationale for this is that
3900 now the receiver can verify whether the channel message decrypted
3901 correctly and also when private keys are set for the channel the
3902 receiver can decrypt the packet with several keys and check from
3903 the MAC which key decrypted the message correctly.
3905 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3906 lib/silccrypt/silccipher.[ch].
3908 * Added silc_hash_len to return the digest length into the
3909 lib/silcrypt/silchash.[ch].
3911 * Rewrote parts of Silc Channel Payload interface in the
3912 lib/silccore/silcchannel.[ch]. The encode function now also
3913 encrypts the packet and parse function decrypts it.
3915 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Fixed a minor formatting bug in the SKE's key material processing.
3918 It actually might have processed the keys wrong way resulting
3921 * Redefined the mandatory HMAC algorithms and added new algorithms.
3922 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3923 and hmac-md5 truncated to 96 bits. The mandatory is now
3924 hmac-sha1-96. Rest are optional (including the one that used
3925 to be mandatory). Rationale for this is that the truncated HMAC
3926 length is sufficient from security point of view and can actually
3927 make the attack against the HMAC harder. Also, the truncated
3928 HMAC causes less overhead to the packets. See the RFC2104 for
3931 * Added new [hmac] configuration section. The SKE used to use
3932 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3933 is of course wrong. The official names that must be proposed in
3934 the SKE are the ones defined in the protocol specification
3935 (hmac-sha1-96 for example). The user can configure any hmac
3936 using any hash function configured in the [hash] section. At
3937 least, the mandatory must be configured.
3939 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3941 * Added HMAC list to the SKE proposal list. It has now both
3942 hash algorithm list and HMAC list. This makes the protocol
3943 incompatible with previous versions. The SKE now seems to work
3944 the way it is supposed to work, for the first time actually.
3946 * Defined plain Hash algorithms to the protocol specification.
3949 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Implemented support for key agreement packets into the server.
3952 Added functions silc_server_key_agreement and
3953 silc_server_send_key_agreement. Other than these functions,
3954 server has nothing to do with this packet.
3956 * Added support for private message key packets into the server.
3957 Added functions silc_server_private_message_key and
3958 silc_server_send_private_message_key.
3962 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3963 called in the protocol's final callback instead in the END
3964 protocol state. This makes a little more sense and in the same
3965 time in client we can use the same protocol routines for normal
3966 key exchange and to key agreement packet handling as well.
3968 * Added to both client's and server's KE protocol context the
3969 SilcSKEKeyMaterial pointer to save the key material. We will
3970 bring the key material to the protocol's final callback by doing
3971 this. The final callback must free the key material.
3973 * Added SKE's packet_send callback into client's KE protocol
3974 context so that the caller can choose what packet sending function
3975 is used. This way we can use different packet sending when
3976 doing normal SKE when doing key agreement packet handling (in
3977 the key agreement packet handling we do not want to encrypt
3980 * Implemented the responder side of the key agreement routines
3981 in the client. The client can now bind to specified port and
3982 accept incoming key negotiation. The key material is passed
3983 to the application after the protocol is over.
3985 * Implemented the processing of incoming Key Agreement packet
3986 in the client. Added function silc_client_key_agreement to
3989 * Implemented the intiator side of the key agreement routines
3990 in the client. The client can now initiate key agreement with
3991 another remote client. The key material is passed to the
3992 application after the protocol is over.
3994 * Created client_keyagr.c to include all the key agreement
3997 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3998 SILC_TASK_CALLBACK except that it is not static.
4000 * Created client_notify.c and moved the Notify packet handling
4001 from the client.[ch] into that file.
4003 * Created client_prvmsg.c and moved all private message and
4004 private message key routines from the client.[ch] into that file.
4006 * Create client_channel.c and moved all channel message and
4007 channel private key routines from the client.[ch] into that file.
4009 * Changed silc_client_get_client_by_id_resolve to resolve with
4010 WHOIS command instead of IDENTIFY command, in the file
4011 lib/silclient/idlist.c.
4013 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Implemented the SKE's responder side to the Client library.
4017 * When FAILURE is received to the protocol do not trust it
4018 blindly. Register a timeout to wait whether the remote closes
4019 the connection as it should do it, only after that process the
4020 actual failure. This was changed to both client and server.
4022 * Added client_internal.h to include some of the structures
4023 there instead of client.h in lib/silcclient/.
4025 * Added function silc_task_unregister_by_callback to unregister
4026 timeouts by the callback function.
4028 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Some "Incomplete WHOIS info" errors has been appearing on the
4031 log files. Took away the entry->userinfo check from WHOIS
4032 reply sending. The entry->userinfo is now " " if client did not
4033 provide one. I thought this was fixed earlier but something
4034 is wrong still. Let's see if the error still appears.
4036 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed a minor bug in the login when the channel key is
4039 re-generated in the server. It used to generate the key in
4040 wrong order and thus caused problems in the channel traffic.
4042 * Fixed a minor bug in channel key distsribution after
4043 KICK command. The key was not sent to the router even though
4046 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added silc_ske_process_key_material_data as generic routine
4049 to process any key material as the SILC protocol dictates. The
4050 function is used by the actual SKE library but can be used by
4051 applications as well. This relates to the private message keys
4052 and the channel private keys since they must be processed the
4053 same way the normal SILC session keys. The protocol dictates
4054 this. Affected files: lib/silcske/silcske.[ch].
4056 Added also silc_ske_free_key_material to free the
4057 SilcSKEKeyMaterial structure.
4059 * Defined silc_cipher_set_key function to set the key for
4060 cipher without using the object's method function. The affected
4061 files: lib/silccrypt/silccipher.[ch].
4063 * Implemented silc silc_client_add_private_message_key,
4064 silc_client_add_private_message_key_ske,
4065 silc_client_del_private_message_key,
4066 silc_client_list_private_message_keys and
4067 silc_client_free_private_message_keys functions in the
4070 Added functions silc_client_send_private_message_key to send
4071 the Private Message Key payload and silc_client_private_message_key
4072 to handle incoming Private Message Key payload.
4074 * Added Cipher field to the Private Message Key payload to set
4075 the cipher to be used. If ignored, the default cipher defined
4076 in the SILC protocol (aes-256-cbc) is used.
4078 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Removed lib/silcclient/ops.h file.
4082 Redefined parts of the SILC Client Library API. Created new
4083 file silcapi.h that deprecates the ops.h file and defines the
4084 published Client Library API. Defined also private message key
4085 API and channel private key API into the file.
4087 This is the file that the application must include from the
4088 SILC Client Library. Other files need not be included by
4089 the application anymore.
4091 * Added new key_agreement client operation callback and also
4092 defined the Key Agreement library API for the application.
4094 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4097 is used by clients to request key negotiation between another
4098 client in the SILC network. If the negotiation is started it
4099 is performed using the SKE protocol. The result of the
4100 negotiation, the secret key material, can be used for example
4101 as private message key.
4103 Implemented the Key Agreement payload into the files
4104 lib/silccore/silauth.[ch].
4106 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Redefined ciphers for the SILC protocol. Added some new ciphers
4109 and defined the key lengths for the algorithms. Changed the
4110 code accordingly. The default key length is now 256 bits.
4112 * Fixed SKE key distribution function silc_ske_process_key_material
4113 when the key length is more than 128 bits. The default key
4114 length in SILC is now 256 bits.
4116 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4117 to indicate unsupported algorithm.
4119 * Renamed rijndael.c to aes.c and all functions as well.
4121 * Fixed a long standing channel key setting bug in client library.
4122 Weird that it has never surfaced before.
4124 * Fixed bug in channel deletion. If the entire channel is removed
4125 then it must also delete the references of the channel entry
4126 from the client's channel list as the client's channel entry and
4127 the channel's client entry share same memory.
4129 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Implemented CONNECT and SHUTDOWN commands in the client.
4133 * Implemented CLOSE command to the client.
4135 * Added the function silc_idlist_find_server_by_name into the
4136 files silcd/idlist.[ch].
4138 Added the function silc_idlist_find_server_by_conn into the
4139 files silcd/idlist.[ch].
4141 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * DIE command was renamed to SHUTDOWN. Updated the both code
4146 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4147 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4149 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4152 * Added function silc_server_create_connection function to create
4153 connection to remote router. My server implementation actually
4154 does not allow router to connect to normal server (it expects
4155 that normal server always initiates the connection to the router)
4156 so the CONNECT command is only good for connecting to another
4159 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4162 or some other client was kicked from the channel.
4164 Implemented the handling of the notify type to both client
4167 Implemented silc_server_send_notify_kicked to send the KICKED
4168 notify. It is used to send it to the server's primary router.
4170 * Implemented the KICK command into server and client.
4172 * Added `query' argument to the silc_idlist_get_client function
4173 to indicate whether to query the client from server or not if
4176 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4177 to indicate that the client is not channel founder.
4181 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Removed the rng context from SilcPacketContext structure and
4184 changed that the packet routine uses the Global RNG API.
4186 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Added support for quit message that client can "leave" on the
4189 channel when it quits the SILC. It is ditributed inside the
4190 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4192 Added silc_server_free_client_data that will take the
4193 signoff message as argument.
4195 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4197 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Updated parts of the protocol specification to keep it up
4202 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4205 payloads in one packet.
4207 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4208 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4209 use now the new List flag.
4211 * Also deprecated the following packet types: REPLACE_ID,
4212 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4214 * Added list support for Notify packet in server.
4216 * Added silc_server_send_notify_channel_change to send the
4217 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4218 the silc_server_send_replace_id.
4220 * Added silc_server_send_notify_nick_change to send the
4221 NICK_CHANGE notify type. Deprecates the function
4222 silc_server_send_replace_id.
4224 * Added silc_server_send_notify_join to send the JOIN notify type.
4225 Deprecates the function silc_server_send_new_channel_user.
4227 * Added silc_server_send_notify_leave to send LEAVE notify type.
4228 Deprecates the function silc_server_send_remove_channel_user.
4230 * Added silc_server_send_notify_cmode and
4231 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4232 types. Deprecates the silc_server_send_set_mode function.
4234 * Added SERVER_SIGNOFF notify type to indicate that server has
4235 quit. This means that all clients on the channel from that
4236 server will drop. This can be also used when netsplit happens.
4238 Deprecated REMOVE_ID packet type since it is not needed anymore
4241 Added silc_server_send_notify_server_signoff to send the
4242 SERVER_SIGNOFF notify type. Deprecates the function
4243 silc_server_send_remove_id.
4245 Added also silc_server_send_notify_signoff to send the
4246 SIGNOFF notify type.
4248 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4249 SILC protocol from this day on. Changed the protocol
4250 specification as well.
4252 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4253 notify type. It is used between routers to notify about
4254 topic changes on a channel.
4256 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4259 * Partly updated the protocol specification to comply with the
4260 changes now made. It is still though a bit outdated.
4262 * The JOIN notify type now takes one extra argument <Channel ID>.
4263 The packet used to be destined to the channel but now the
4264 JOIN type may be sent as list thus it is impossible to
4265 destine it to any specific channel. By adding this argument
4266 it is again possible.
4268 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Added CREDITS file. The CHANGES and CREDITS file will appear
4271 in the distribution as well.
4273 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4276 types in the server's silcd/packet_receive.c.
4278 * Implemented CMODE and CUMODE to work in router environment.
4280 * Fixed minor encoding and decoding buglet from the
4281 lib/silccore/silcmode.c.
4283 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4286 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4288 * Changed all SilcConfigServer* and silc_config_server* to
4289 SilcServerConfig* and silc_server_config*, respectively.
4292 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Associated the ID (client or server ID) to the Authentication
4295 Payload to avoid any possibility of forging. Updated the
4296 protocol specification and the code accordingly.
4298 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * The RSA key length is now save to the RsaKey context in the
4301 key generation process in lib/silccrypt/rsa.c. The key length
4302 is now used to figure out the maximum size of the block allowed
4303 to be encrypted/signed.
4305 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4306 is equivalent to the silc_mp_mp2bin but does not allocate any
4309 * Changed silc_mp_mp2bin API to take length argument. If it is
4310 non-zero then the buffer is allocated that large. If zero, then
4311 the size is approximated using silc_mp_sizeinbase, which however
4314 * Created Global RNG API which is global RNG that application can
4315 initialize. After initializing, any routine anywhere in the
4316 code (including library) can use RNG without allocating a new
4317 RNG object. This was done to allow this sort of use of the
4318 RNG in code that has no chance to allocate RNG object. All
4319 applications currently allocate this and many routines in the
4320 library use this. Affected file lib/silccrypt/silcrng.[ch].
4322 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4323 it to use the Global RNG API.
4325 * Defined Authentication Payload into protocol specification that
4326 is used during SILC session to authenticate entities. It is
4327 used for example by client to authenticate itself to the server
4328 to obtain server operator privileges.
4330 Implemented this payload into the lib/silccore/silcauth.[ch].
4331 Implemented also routines for public key based authentication
4332 as the new protocol specification dictates.
4334 Moved definitions of different authentication methods from
4335 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4337 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4338 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4339 silc_pkcs_verify_with_hash functions into the file
4340 lib/silccrypt/silcpkcs.[ch].
4342 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * The client entry's userinfo pointer must be always valid.
4345 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4346 will fail since it requires the userinfo. Now, the userinfo
4347 is allocated as "" if actual userinfo does not exist. Actually,
4348 it must exist and it is totally Ok to drop client connections
4349 that does not announce the userinfo. However, we will make
4350 this workaround for now.
4352 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4353 to return the remote port by socket.
4355 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4358 SILC_SERVER_PENDING_EXEC and added an new macro
4359 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4360 data or when error occurs while processing the pending command.
4362 Added new argument `destructor' into silc_server_command_pending
4363 and to the SilcServerCommandPending object. This destructor is
4364 now called after calling the pending callback or if error occurs
4365 immediately. If error occurs the actual pending callback won't
4366 be called at all - only the destructor. The destructor may be
4367 NULL if destructor is not needed.
4369 All this applies for client library code as well. Similar
4370 changes were made there as well for the pending commands.
4372 In the client, the application must now allocate the
4373 SilcClientCommandContext with the silc_client_command_alloc
4376 * Added reference counter to the SilcServerCommandContext. Added
4377 function silc_server_command_alloc and silc_server_command_dup
4380 Same type of functions added to the client library for the same
4383 * Removed the cmd_ident from IDListData away since it is now
4384 global for all connections. It is the command identifier used
4385 in command sending and with pending commands. The affected file
4388 * Added reference counter to the SilcSocketConnection objecet to
4389 indicate the usage count of the object. The object won't be
4390 freed untill the reference counter hits zero. Currently only
4391 server uses this, and client ignores it. The client must be
4392 set to use this too later. The affected files are
4393 lib/silccore/silcsockconn.[ch]. Added also the function
4394 silc_socket_dup to increase the reference counter.
4396 This was mainly added because it is possible that the socket
4397 is removed underneath of pending command or other async
4398 operation. Now it won't be free'd and proper DISCONNECTING
4399 flags, etc. can be set to avoid sending data to connection that
4400 is not valid anymore.
4402 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4403 the connection. After that it sets SILC_SET_DISCONNECTED.
4404 It is, however, possible that the socket data is not still freed.
4405 The silc_server_packet_process now checks that data is not
4406 read or written to connection that is DISCONNECTED. The socket
4407 get's freed when the reference counter hits zero.
4409 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Changed the client operation API: channel_message operation's
4412 `sender' is now the client entry of the sender, not the nickname
4413 and the `channel' is the channel entry, not the channel name.
4415 In the private_message operation the `sender' is now also the
4416 client entry of the sender not the nickname.
4418 Affected file is lib/silcclient/ops.h and all applications
4419 using the client operations.
4421 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Moved the calling of ops->connect() from connect_to_server_final
4424 into receive_new_id functin since that is the point when the
4425 client is actually allowed to send traffic to network. The
4426 affected file is lib/silcclient/client.c.
4428 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4431 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4432 (if needs broadcasting) instead of broadcasting the packets one
4433 by one which would make a burst in the network traffic.
4435 * Added `broadcast' argument to the functions in silcd/server.[ch]
4436 silc_server_create_new_channel[_with_id] to indicate whether
4437 to send New Channel packet to primary router.
4439 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Added new function into the silcd/server.[ch] files:
4442 silc_server_create_new_channel_with_id to create new channel with
4443 already existing Channel ID.
4445 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4446 lib/silccore/silcpacket.h. This packet is used t send list of
4447 Set Mode payloads inside one packet. Server uses this to set
4448 the modes for the channels and clients on those channels, that it
4449 announced to the router when it connected to it. The protocol
4450 specification has been updated accordingly.
4452 * The silc_server_new_channel did not handle the packet coming
4453 from normal server as it normally does not send that. However,
4454 when it announces its channels it does send it. Implemented
4455 the support for that.
4457 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4458 into the file lib/silccore/id.h.
4460 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Fixed memory leaks in the functions silc_idlist_del_client,
4463 silc_idlist_del_channel and silc_idlist_del_server in the file
4464 silcd/idlist.c. All of those leaked like a sieve.
4466 * Fixed some small memory leaks in the client's function
4467 silc_client_notify_by_server.
4469 * Added functions into silcd/server.c: silc_server_announce_clients,
4470 silc_server_announce_channels and silc_server_announce_server.
4471 These functions are used by normal and router server to announce
4472 to its primary router about clients, channels and servers (when
4473 router) that we own. This is done after we've connected to the
4476 These functions effectively implements the following packet types:
4477 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4478 and SILC_PACKET_NEW_ID_LIST.
4480 * Added new functions into the silcd/packet_receive.[ch]:
4481 silc_server_new_id_list, silc_server_new_channel_list and
4482 silc_server_new_channel_user_list to handle the incoming
4483 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4485 * Added support of changing Channel ID in the function
4486 silc_server_replace_id. If the server that announces a channel
4487 to the router already exists in the router (with same name but
4488 with different Channel ID), router is responsible to send
4489 Replace ID packet to the server and force the server to change
4490 the Channel ID to the one router has.
4492 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4493 client that the Channel ID has been changed by the router. The
4494 normal server sends this to the client. Client must start using
4495 the new Channel ID as the channel's ID.
4497 Implemented handling of this new type into lib/silcclient/client.c
4498 into the function silc_client_notify_by_server.
4500 * Added new function silc_idlist_replace_channel_id into the files
4501 silcd/idlist.[ch] to replace the Channel ID.
4503 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Call silc_server_command_identify_check always when processing
4506 the IDENTIFY command in silcd/command.c
4508 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4511 send keepalive packets. The packet can be sent by clients,
4512 servers and routers.
4514 Added function silc_socket_set_heartbeat into the file
4515 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4516 If not set, the heartbeat is not performed. The actual
4517 heartbeat is implemented in the low level socket connection
4518 library. However, application is responsible of actually
4521 Added silc_server_send_heartbeat to send the actual heartbeat
4522 packet into silcd/packet_send.[ch]. Server now performs
4523 keepalive with all connections.
4525 * Added silc_task_get_first function into lib/silcutil/silctask.c
4526 to return the timeout task with shortest timeout. There was a bug
4527 in task unregistration that caused problems. TODO has been
4528 updated to include that task system must be rewritten.
4530 * The client library will now resolve the client information when
4531 receiving JOIN notify from server for client that we know but
4532 have incomplete information.
4534 * Rewrote parts of silc_server_remove_from_channels and
4535 silc_server_remove_from_one_channel as they did not remove the
4536 channel in some circumstances even though they should've.
4538 * Encryption problem encountered in server:
4540 The LEAVE command used to send the Channel Key packet to the
4541 router immediately after generating it. However, the code
4542 had earlier sent Remove Channel user packet but not immediately,
4543 ie. it was put to queue. The order of packets in the router
4544 was that Channel Key packet was first and Remove Channel User
4545 packet was second, even though they were encrypted in the
4546 reverse order. For this reason, MAC check failed. Now, this
4547 is fixed by not sending the Channel Key packet immediately but
4548 putting it to queue. However, this is more fundamental problem:
4549 packets that are in queue should actually not be encrypted
4550 because packets that are sent immediately gets encrypted
4551 actually with wrong IV (and thus MAC check fails). So, packets
4552 that are in queue should be encrypted when they are sent to
4553 the wire and not when they put to the queue.
4555 However, the problem is that the current system has not been
4556 designed to work that way. Instead, the packet is encrypted
4557 as soon as possible and left to the queue. The queue is then
4558 just purged into wire. There won't be any fixes for this
4559 any time soon. So, the current semantic for packet sending
4562 o If you send packet to remote host and do not force the send
4563 (the packet will be in queue) then all subsequent packets to the
4564 same remote host must also be put to the queue. Only after the
4565 queue has been purged is it safe again to force the packet
4568 o If you send all packets immediately then it safe to send
4569 any of subsequent packets through the queue, however, after
4570 the first packet is put to queue then any subsequent packets
4571 must also be put to the queue.
4573 Follow these rules and everything works fine.
4575 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Added new function silc_server_remove_clients_by_server to
4578 remove all client entries from ID list when the server connection
4579 is lost. In this case it is also important to invalidate all
4580 client entires as they hold the invalid server entry. This
4581 fixes fatal bug when server has lost connection and will reconnect
4584 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Made some sanity checks to silc_server_daemonise like to check
4587 whether the requested user and group actually exists.
4589 * Added sanity check to SKE's silc_ske_responder_finish to check
4590 that the public and private key actually is valid.
4592 * Invalidate the client's nickname when receiving Replace ID
4593 packet and the Client ID is being replaced. This means that the
4594 server will query the nickname if someone needs it (client)
4597 * Sort the ID Cache in client library when the ID Cache data
4598 has changed (needs sorting).
4600 * Do not allow for SILC client to create several connections to
4601 several servers. The client does not support windows right now
4602 and generating multiple connections causes weird behaviour.
4604 Irssi-silc client does support windows and can handle several
4605 connections without problems, see: www.irssi.org and SILC plugin.
4607 * Fixed some places where client was added to the IDList. The
4608 rule of thumb is following (in order to get everything right):
4609 If the client is directly connected local client then the
4610 `connection' argument must be set and `router' argument must be
4611 NULL to silc_idlist_add_client function. If the client is not
4612 directly connected client then the `router' argument must
4613 bet set and the `connection' argument must be NULL to the
4614 silc_idlist_add_client function.
4616 * The funtion silc_server_packet_send_local_channel actually did
4617 not check whether the client was locally connected or not. It
4618 does that now. Fixed a bug related to LEAVE command.
4620 * Fixed Remove Channel User payload parsing bug in server's
4621 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4623 * The server's silc_server_save_channel_key now checks also the
4624 global ID list for the channel as it might not be in the local
4625 list. Fixed a bug related to LEAVE command.
4627 * Is this the end of the [<unknown>] buglet that has been lurking
4628 around for a long time? A little for loop fix in server's
4629 silc_server_command_whois_parse that is used by both IDENTIFY
4630 and WHOIS command. At least, this was a clear bug and a cause
4631 of one type of [<unknown>] buglet.
4633 * WHOIS and IDENTIFY commands call the function
4634 silc_server_command_[whois/identify]_check function even if
4635 we are not router server.
4637 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Added --with-gmp configuration option. If set the GMP
4640 is always compiled in the SILC source tree. If not set then
4641 it is checked whether the system has the GMP3 installed. If
4642 it has then the GMP won't be compiled (the system's headers
4643 and library is used), if it doesn't have it then the GMP is
4644 compiled in the SILC source tree.
4646 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Changed RSA private exponent generation to what PKCS #1
4649 suggests. We try to find the smallest possible d by doing
4650 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4651 not security fix but optimization.
4653 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Added new config entry [Identity] to fork the server and run
4656 it as specific user and group. A patch from Bostik.
4658 * Imported Dotconf configuration library into lib/dotconf.
4659 This will be used to create the SILC configuration files later.
4660 It will appear in the distsribution after this commit.
4662 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * A big code auditing weekend happening. Auditing code for
4665 obvious mistakes, bugs and errors. Also, removing any code
4668 Removed files for being obsolete:
4670 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4671 inline in the file lib/silcutil/silcbuffer.h)
4673 o lib/silcutil/silcbufutil.c (the header has inline versions)
4675 Changed code to fix possible error conditions:
4677 o The buffer formatting routines now check that the destination
4678 buffer really has enough space to add the data. This applies for
4679 both buffer formatting and unformatting
4680 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4681 unformatting was changed to accomodate following rules:
4682 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4683 sent to the function while XXX_*STRING will not allocate or copy
4684 the data into the buffer. Instead it sets the pointer from the
4685 buffer into the pointer sent as argument (XXX_*STRING used to
4686 require that the pointer must be allocated already). This change
4687 makes this whole thing a bit more consistent and more optimized
4688 (note that the data returned in the unformatting with XXX_*STRING
4689 must not be freed now). The routines return now -1 on error.
4691 o Tried to find all code that use buffer_format and buffer_unformat
4692 and added return value checking to prevent formatting and
4693 especially unformatting errors and possible subsequent fatal
4696 o Changed ske->x and ske->KEY to mallocated pointers in
4697 lib/silcske/silcske.h. Fixed possible data and memory leak.
4699 o Added return value checking to all *_parse* functions. Fixed
4700 many memory leaks as well.
4702 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4703 so that buffer overflows would not happen. All code now also
4704 checks the return value as it can fail.
4706 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Added reconnection support to server if the normal server looses
4709 its connection to the router (for example if router is rebooted).
4710 The server performs normal reconnection strategy implemented
4711 to the server. Affected file silcd/server.c.
4713 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added new packet type SILC_PACKET_SET_MODE that is used to
4716 distribute the information about changed modes (for clients,
4717 channels and clients channel modes) to all routers in the
4718 network. Updated the protocol specification accordingly.
4720 Added functions into silcd/packet_send.c and
4721 silcd/packet_receive.c: silc_server_send_set_mode,
4722 silc_server_set_mode.
4724 Added new files silcmode.[ch] into lib/silccore that implements
4725 the encoding and decoding of Set Mode Payload. Added new type
4726 SilcSetModePayload. Moved the definitions of different modes
4727 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4729 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Oops, a little mistake in server's connection authentication
4732 protocol. The protocol is not ended with FAILURE but with
4733 SUCCESS if the authentication is Ok. :) Affected file is
4736 * Implemented NICK_CHANGE notify handling in server in the file
4737 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4738 the local clients on the channel. After the changing nickname
4739 in router environment snhould work and the [<unknown>] nickname
4740 should appear no more.
4742 The silc_server_replace_id function that receives the Replace ID
4743 payload now sends the NICK_CHANGE notify type also in the file
4744 silcd/packet_receive.c
4746 * Changed WHOIS and IDENTIFY command to support the maximum amount
4747 of arguments defined in protocol specs (3328 arguments). This
4748 fixed a bug that caused problems when there were more than three
4751 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Added extra parameter, command identifier, to the
4754 silc_client_send_command so that explicit command identifier
4757 Changed that ID list routines uses specific command identifier
4758 when sending WHOIS/IDENTIFY requests to the server so that they
4759 can be identified when the reply comes back.
4761 Affected files lib/silcclient/command.[ch],
4762 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4764 * Added `sender' argument to silc_server_packet_send_to_channel
4765 to indicaet the sender who originally sent the packet to us
4766 that we are now re-sending. Ignored if NULL. Affected file
4767 silcd/packet_send.[ch].
4769 * Added some server statistics support in silcd/server_internal.h
4770 SilcServerStatistics structure and around the server code. Also
4771 send some nice statistics information when client is connecting
4774 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Fixed channel ID decoding in server's JOIN command reply in
4777 silcd/command_reply.c
4779 * Fixed braodcasting of replace ID payload to not to send it if
4780 we are standalone server in silcd/packet_receive.c.
4782 * Fixed all channel message sending routines to not to send
4783 packets to clients that has router set, since they are routed
4784 separately in the same function earlier. Affects file
4785 silcd/packet_send.c and all channel packet sending functions.
4787 * In USERS reply, res_argv[i] are not allocated, the table
4788 is allocated. Thus changed that free the table, not its
4791 * In server's whois_check and identify_check if the client is
4792 locally connected do not send any WHOIS commands - they are not
4795 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Fixed some minor bugs in client when sending WHOIS command. The
4798 arguments was in wrong order.
4800 * Removed statis function add_to_channel from server in
4801 silcd/command.c that was previously used with the joining but
4804 * Tested USERS command in router environment successfully with two
4805 routers, two servers and two clients.
4807 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Reorganized the USERS command and command reply in client library
4810 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4811 When the command is given by user we register a pending command
4812 callback that will reprocess the command after the reply has been
4813 received from the server. When reprocessing the packet we then
4814 display the information. Thus, the USERS information is displayed
4815 now in the command callback instead of in the command reply
4816 callback. The processing of the command is same as previously
4817 when server has sent the command reply in the JOINing process.
4819 * Added to USERS command in silcd/command_reply.c to join the client,
4820 we didn't use to know about, to the channel after we've created
4821 a client entry for it. Also, for clienet we did know already still
4822 check whether it is on the channel or not and add it if not.
4824 * Removed silc_server_command_join_notify as the function and its
4827 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Changed the client's pending command handling to the same as the
4830 server's pending command handling. It is also now possible to
4831 execute command reply functions from other command reply
4832 function as the function callbacks for commands and command
4833 replies are one and same. The pending commands are not static
4834 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4835 in client connection context. Thus, pending commands are server
4836 connection specific as it is convenient.
4838 Changed the function silc_client_command_pending and
4839 silc_client_command_pending_del and added new function
4840 silc_client_command_pending_check. Removed the
4841 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4844 * Added cmd_ident, current command identifier, to the client
4845 connection context in lib/silcclient/client.h to keep track on
4846 command identifiers used in command sending. Client's command reply
4847 function handling now supports the mandatory command identifiers.
4849 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4850 funtions in client to fully support pending command callbacks.
4852 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4853 as one of the arguments to the application in the command reply
4856 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4857 before first releasing SILC but came back. Now it is removed again
4858 and should come back nomore. The FORWARDED flag was used only
4859 by the JOINing procedure by forwarding the command packet to router.
4860 Now, the JOINing procedure has been changed to more generic (due
4861 to various router environment issues) and FORWARDED is not needed
4862 anymore for anything. The protocol specification is yet to be
4865 Now, removed silc_server_packet_forward from server and the flag
4866 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4868 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Renamed NAMES command to USERS command. The NAMES was named that
4871 due to historical reasons. Now it is renamed. Also, rewrote
4872 parts of the USERS command. The nickname list is not sent anymore
4873 by the server. Only Client ID and mode lists are sent in the USERS
4874 command. Changed this also to the protocol specification.
4876 The client now resolves the names and stuff after it receives
4877 the USERS list from the server when joining to the channel.
4879 * WHOIS and IDENTIFY commands has been changed to support multiple
4880 Client ID's per command. One can now search for multiple users
4881 in the network by sending only one WHOIS or IDENTIFY command.
4882 Changed the code and the protocol specifications.
4884 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4885 uses silc_server_command_whois_parse to parse the request. */
4887 * If normal server, do not parse the WHOIS and IDENTIFY requests
4888 before sending it to the router. Saves some time.
4890 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Fixed JOIN command on client library. Wrong number of arguments
4893 used to crash the client.
4895 * Added silc_server_channel_has_global function to check whether
4896 channel has global users or not.
4898 * Added silc_server_channel_has_local function to check whether channel
4899 has locally connected clients on the channel.
4901 * The silc_server_remove_from_one_channel now checks whether the
4902 channel has global users or not after given client was removed from
4903 the channel. It also checks whether the channel has local clients
4904 on the channel anymore. If it does not have then the channel entry
4905 is removed as it is not needed anymore.
4907 * The silc_server_notify now checks on JOIN notify whether the joining
4908 client is one of locally connected or global. If it is global then
4909 the channel has now global users on the channel and that is marked
4910 to the channel entry. Also, it now saves the global client to
4911 global list who is joining and JOINs it to the channel. This is
4912 for normal server, that is.
4914 Changed silc_server_send_notify_on_channel,
4915 silc_server_packet_relay_to_channel and
4916 silc_server_packet_send_to_channel check if we are normal server
4917 and client has router set (ie. global client) do not send the
4918 message to that client, as it is already routed to our router.
4920 * Implemented LEAVE notify type handling in silc_server_notify
4923 * Tested LEAVE command in router environment successfully. Tested
4924 with two routers, two servers and two clients.
4928 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4930 * Implemented SIGNOFF notify type handling in silc_server_notify
4933 * silc_server_remove_id now removes the client entry from all channels
4934 it has joined and thusly sends SIGNOFF notify type.
4936 * Rewrote the NAMES list generation in server by removing two excess
4937 loops. The lists are created now inside one loop.
4939 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * silc_server_remove_channel_user checks now also global list
4942 for channel and client.
4944 * silc_server_new_channel_user checks now both local and global
4945 list for channel and client. Fixed a bug in client id decoding.
4946 Used to decode wrong buffer.
4948 * silc_server_channel_message checks now both local and global
4949 list for channel entry.
4951 * Tested channel joining (hence JOIN) in router environment
4952 successfully. Tested with two routers, two servers and two
4955 * Tested channel message sending in router environment successfully.
4957 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Added silc_server_save_channel_key into server.[ch] to save the
4960 received channel key in Channel Key payload processing. It is
4961 also used in JOIN command reply handling.
4963 Equivalent function silc_client_save_channel_key added into
4964 client.[ch] into client library.
4966 * Changed JOIN command reply to send information whether the channel
4967 was created or not (is existing already) and the channel key
4968 payload. Changed protocol specs accordingly.
4970 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4971 the request was sent by ID and not by nickname. Crashed on
4974 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4977 now correctly save the received data.
4979 * silc_server_free_sock_user_data now notifies routers in the
4980 network about entities leaving the network.
4982 At the same time implemented functions silc_server_remove_id
4983 and silc_server_send_remove_id to receive and send REMOVE_ID
4984 packets. The packet is used to notify routers in the network
4985 about leaving entities. The ID removed will become invalid in
4988 * Added function silc_idlist_del_server into server. Removes and
4989 free's server entry from ID list.
4991 * silc_server_private_message function now checks, if we are router,
4992 that the destination ID really is valid ID, naturally.
4994 * In router when NEW_ID packet is received (for new client) the
4995 hash of the Client ID is saved in the ID Cache but the
4996 client->nickname is set to NULL, instead of putting the hash
4999 IDENTIFY command now also checks that client->nickname must be
5000 valid. If it is not if will request the data from the server who
5001 owns the client. Added new function
5002 silc_server_command_identify_check.
5004 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5005 to set the command to already allocated Command Payload.
5007 * Tested private message sending in router environment with two
5008 routers, two servers and two clients. Fixed minor bugs and now
5011 * Fixed segfault from client's NAMES command. Used to crash if
5014 * Forwarded packets must not be routed even if it is not destined
5015 to the receiver. Changed server code comply with this.
5017 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added `require_reverse_mapping' boolean value to ServerParams
5020 structure. If TRUE (not default) the server will require that
5021 the connecting host has fully qualified domain name.
5023 If the reverse mapping is not required and hostname could not be
5024 found the IP address is used as hostname.
5026 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Implemented version string checking to both client and server.
5029 The check is incomplete currently due to the abnormal version
5030 strings used in development version of SILC.
5032 * Changed all command functions in server to use the new
5035 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Changed char *data to unsigned char *data in ID Cache system to
5038 support binary data as ID Cache data. Changed code to support
5039 binary data in lib/silccore/idcache.c.
5041 * Renamed silc_server_packet_relay_command_reply to
5042 silc_server_command_reply as it is normal packet receiving
5043 function. Rewrote the function to accept command replys for
5044 servers and not only for clients.
5046 * Mark remote router always as registered server if we are connecting
5047 to it. Otherwise, commands sent by the router to us are ignored.
5049 * All ID List find routines now returns the ID Cache Entry pointer
5050 as well if requested.
5052 * WHOIS command works now in router environment, tested with two
5053 routers, two servers and two clients.
5055 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5056 in router environment (as it is almost equivalent to WHOIS) but
5057 hasn't been tested thoroughly. Added new functions:
5059 silc_server_command_identify_parse
5060 silc_server_command_identify_send_reply
5061 silc_server_command_identify_from_client
5062 silc_server_command_identify_from_server
5064 * Disabled route cache adding because adding two different ID's with
5065 same IP replaces the old cache entry thus giving wrong route.
5066 The entry->router->connection is always the fastest route anyway
5067 so route cache may not be needed. Of course, new routes maybe
5068 established after receiving the ID when the entry->router->connection
5069 might not be anymore the most optimal.
5071 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Add route cache for received ID for fast routing.
5075 * Added silc_server_packet_route to route received packet on router
5076 that is not destined to us.
5078 * Renamed silc_server_get_route to silc_server_route_get.
5080 * Added id_string and id_string_len fields into SilcServer to
5081 include encoded ServerID for fast comparing without excess
5082 encoding of the ID's.
5084 * Cleaned up WHOIS command on server side. Added following static
5087 silc_server_command_whois_parse
5088 silc_server_command_whois_check
5089 silc_server_command_whois_send_reply
5090 silc_server_command_whois_from_client
5091 silc_server_command_whois_from_server
5093 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5094 arguments in command replies. All command functions should be
5095 updated to use this macro.
5097 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Minor typo fixes on command reply handling on server.
5101 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Added silc_server_command_add_to_channel internal routine to add
5104 the client to the channel after router has created the channel and
5105 sent command reply to the server.
5107 * Added generic silc_server_send_command to send any command from
5110 * Use static buffer with ID rendering instead of duplicating data.
5112 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Fixed a channel user mode bug when joining to a channel server gave
5115 everybody channel founder rights, oops.
5117 * We mark ourselves as the router of the incoming server connection
5118 if we are router ourselves. This way we can check in some packet
5119 sending functions whether it is locally connected server. For
5120 incoming router connections we put NULL.
5122 * For router sending packets locally means now always sending the
5123 packet cell wide; to local clients and local servers. For normal
5124 server sending packet locally means sending it to only local
5127 * Fixed the JOIN command to really work in router environment. If the
5128 channel is created it is always created by the router. Router is
5129 also responsible of making the initial joining to the channel,
5130 sending JOIN notify to the sending server and distributing
5131 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5132 does not exist server doesn't do anything else but forward the
5133 command to the router which performs everything.
5135 * Added silc_server_send_channel_key function to send the Channel Key
5138 * Added silc_server_create_channel_key to create new channel key. The
5139 channel key is now re-generated everytime someone joins or leaves
5140 a channel, as protocol dictates. Note: channel->key_len is the
5143 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5146 packet_receive.[ch] to separate packet sending and receiving
5147 routines. The server.[ch] now includes everything else including
5148 actual packet processing (writing and reading data) and other
5151 Renamed silc_server_private_message_send_internal to
5152 silc_server_send_private_message. The routine is still though
5153 used only to relay private messages as server does not send
5154 private messages itself.
5156 Renamed silc_server_new_channel to silc_server_create_new_channel
5157 and added new function sicl_server_new_channel that handles the
5158 incoming New Channel packet. Added also new sending function
5159 silc_server_send_new_channel to send New Channel Payload.
5161 * Added new function silc_server_notify to process incoming notify
5162 packet to the server/router. Server may then relay the notify
5163 to clients if needed.
5165 * Added new function silc_server_new_channel_user to process incoming
5166 New Channel User packet. Router will redistribute the packet and
5167 send JOIN notify to its local clients and locally connected servers
5168 if needed. Normal server will send JOIN notify to its local client
5169 on same channel when received this packet. Added also corresponding
5170 sending function silc_server_send_new_channel_user to sent the
5173 * Added boolean route argument to send_notif_to_channel and
5174 packet_send_to_channel functions to attempt to route the packet
5175 if it is TRUE and send only locally if it is FALSE.
5177 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * silc_server_replace_id now broadcasts the received replace ID
5180 packet if it is not broadcast packet already. The router must
5181 broadcast to inform other routers about changed ID.
5183 * Added backpointer to server's router into SilcServer context in
5184 silcd/server_internal.h.
5186 * Fixed silc_server_packet_broadcast to send correct broadcast
5189 * The channel key is now distributed to the local client as soon
5190 as it is received from the router (in router environment) so that
5191 no other packet may be sent for the channel until client has
5194 * silc_server_remove_channel_user now broadcasts the received
5195 Remove Channel User packet if it is not broadcast packet already.
5196 The router must broadcast to inform other routers about removed
5199 * Added users field into SilcPacketContext that is a reference count
5200 of the context. One can increase the reference count by calling
5201 silc_packet_context_dup which is now changed to just increase the
5202 reference count instead of duplicating the data. The reference
5203 count is decresed by calling silc_packet_context_free that will
5204 free the data after the reference count hits zero.
5206 For now on the packet context and everything allocated into it
5207 (including the raw packet from network) must be freed by calling
5208 the new silc_packet_context_free function. Added also new function
5209 silc_packet_context_alloc that must be used now to allocate the
5210 context. This also means that if a routine is asynchronous from
5211 silc_[client/server]_packet_parse_type the packet context must
5212 be duplicated by calling silc_packet_context_dup. Otherwise it
5213 gets free'd after silc_[client/server]_packet_parse_type returns.
5214 Also, one must remember that if packet is duplicated then its
5215 reference count must be decresed by calling the free function as
5216 many times as it was duplicated.
5218 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5219 from both client and server.
5221 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Made joining to a channel working in router environment.
5225 * Cleaned up JOIN command on server side and create function
5226 silc_server_command_join_channel internal routine to make the
5229 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Changed silc_command_pending list to SilcDList. Also, added
5232 `ident' field to SilcServerCommandPending structure to identify
5233 the reply and to call correct callback.
5235 Added silc_server_command_pending_check function to replace the
5236 corresnponding macro. The silc_command_pending list is not
5239 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5240 to set identifier to previously allocated Command Payload. It
5241 is used to set identifier for command when resending Command
5244 * Added silc_command_payload_encode_payload to encode Command
5245 Payload buffer from SilcCommandPayload structure.
5247 * Added silc_argument_payload_encode_payload to encode Argument
5248 payload buffer from SilcArgumentPayload structure.
5250 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Changed WHOIS command to support router connection on server side.
5253 The whois request is always sent to router unless the server is
5254 standalone server. After server has received the reply from the
5255 router will it send the reply to the client.
5257 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5258 broadcast received broadcast packet. The function is used only
5259 by router. The broadcast packet is always sent to the router's
5262 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5263 render given ID to printable string, for log files for example.
5265 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Made basic router to router connections working. At least they
5268 can now connect to each other but nothing really works the way
5269 they are supposed - yet.
5271 * Added new initiator token to RouterConnection configuration
5272 file in silcd/serverconfig.[ch]. It is used to tell whether we
5273 are the initiator to the remote router or whether we'll expect
5274 the other end to connect.
5276 * Moved registering of listener task to silc_server_init, hence
5277 the server starts listenning as soon as it is run, even if it
5278 does not have connections to other routers. Let's see how well
5281 * Changed default connection retry timeouts for more suitable in
5284 * Removed cipher and such arguments from silc_idlist_add_client
5285 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5286 Added new function silc_idlist_add_data to add the keys and stuff
5289 * Added SilcIDListData structure and added it to SilcClientEntry
5290 and SilcServerEntry as their first field in the structure. This
5291 way we can explicitly cast the ID entries to the SilcIDListData
5292 structure and get common data for the entries. In past, we had
5293 to first check what type of connection it is and then cast it to
5294 correct ID entry type. Now, we can directly cast the opaque
5295 pointer to the SilcIDListData (no matter what ID entry it actually
5296 is) and get the data needed.
5298 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5301 in some circumstances even if threre were timeout tasks, though not
5302 IO tasks, but tasks anyway. Now fixed.
5304 * Defined SilcServerConnection structure to hold connection specific
5305 stuff about directly connected servers and routers. The definition
5306 is currently in silcd/server_internal.h. I thought about having
5307 a bit more important role fro this struct but for now it is used
5308 only when connecting to other server (or router actually).
5310 * Added connecting retry support in server when connecting to
5311 router(s). The retry feature implement exponential backoff
5312 algorithm. Also, added SilcServerParams structure to hold default
5313 parameters for server. For now, it include these retry settings
5314 and are hard coded. After server is moded to be as Silc Server
5315 Library this structure will be more important.
5317 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Changed client librarys channel->clients table to SilcList and
5320 changed code accordingly.
5322 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Changed client's channel table to SilcList and changed code
5325 accordingly. Also changed SilcChannelClientEntry to include back-
5326 pointer to the channel so that client entry can use that structure
5327 as list as well and we have fast cross-reference to the channel.
5328 This change dramatically decreased the complexity of channel
5329 handling with client entry and vice versa (removed one extra
5330 loop when searching for channel entry from many functions).
5332 * Changed server->sim from table to SilcDList and changed code
5335 * NAMES command can now be used from user interface. It will show
5336 the user list on the channel, neatly.
5338 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5339 Code now saves realname of the user if it becomes available.
5341 * Renamed configure.in to configure.in.pre and made ./prepare
5342 script to automatically add correct version string to
5343 configure.in which it creates from configure.in.pre.
5345 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5347 * NAMES command reply now shows users mode with the nickname when
5350 * Moved silc_client_ch[u]mode[_char] functions from
5351 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5352 place sucks, they are utility functions and should be in some
5355 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5357 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5360 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5364 * Added TRQ (efficient deque and list library) into lib/trq. This is
5365 a very good list library that is currently used in the SILC. Defined
5366 SilcList API over the library because I didn't like the API very
5367 much. See lib/trq/silclist.h for the API and examples of how to
5368 use the API. Fixed various places in the code to use the new
5369 SilcList API. The SilcList is meant for lists that has a structure
5370 already defined as a list. It is not suitable to add just some
5371 context to the list (in TRQ, the context is the list actually).
5373 So, I defined SilcDList that can be used for the purpose where
5374 predefined list structure does not exit. This can be used as
5375 such list. Now some context just can be added to the SilcDList.
5376 Currently this list is not used in the SILC just yet, though there
5377 are a lot places where this can replace dynamically allocated
5378 tables and I will fix these places, later, to use SilcDList.
5379 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5380 and use TRQ internally).
5382 Also fixed some annoying warning messages that the original TRQ
5383 code generated. Also minor changes to TRQ's Makefile.in.
5385 * Added support for querying by Client ID to both WHOIS and
5386 IDENTIFY commands into server, as required by the protocol.
5388 * Removed method function pointers from SilcBuffer structure. They
5389 weren't used to anything and just increased the context size for
5390 no good reason. This change also made silc_buffer_alloc and
5391 silc_buffer_free functions inline functions.
5393 * Disabled command flooding detection support until it's fixed so
5394 that it accepts commands in but does not execute them more than once
5397 * Added silc_net_localhost(), to return local hostname, into
5398 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5399 that must be initialized before calling silc_client_init.
5401 * Added new function: silc_server_send_notify_on_channels to send
5402 notify messages to all channels client has joined. It is assured
5403 that the message is sent only once per client.
5405 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5406 lib/silcutil/silcutil.[ch] as silc_format function. The new
5407 function is generic and is used by server as well, not only by
5408 the logging routines.
5410 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5411 the provided version string was not acceptable. Added new function:
5412 silc_ske_check_version into lib/silcske/silcske.h. The function
5413 must be implemented by the application (client or server) and it
5414 does not reside in the SKE library. The function checks the version
5415 string remote end sent.
5417 * Added back pointers (to opaque context and to SilcSocketConnection)
5418 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5420 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5421 duplicate packet context structure.
5423 * Changed `notify' client operation to send same arguments as client
5424 receives from server except for ID's. ID's are mapped to correct
5425 ID entry and that is returned. Also, if channel entry is not sent
5426 by server but the notify is for channel the channel entry is sent
5427 to application (otherwise application doesn't know that it is for
5428 channel (library gets it from packet's Destination ID)).
5430 * Added silc_client_remove_from_channels into client library to
5431 remove a client from all channels it has joined to. Used when
5432 received SIGNOFF notify from server. Added also new function
5433 silc_client_replace_from_channels to replace old ID entry with
5434 new ID entry on all channels. Used when received NICK_CHANGE
5437 * Fixed ID Cache list handling in silc_idlist_get_client in
5438 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5439 to get (or query) client by ID.
5441 * Updated TODO list.
5443 * Added connection authentication status message defined by the
5444 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5445 support for these into the code in client and server side.
5447 * Added generic function silc_client_send_command to send any command
5448 with variable argument list. Application should use this function
5449 to send commands if the command functions provided by the library
5450 does not suite for the application's user interface needs.
5452 * Added new `failure' client operation. Application is notified about
5453 received failure packet if client is executing a protocol. In this
5454 case the protocol's execution has failed.
5456 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5457 is required by the protocol.
5459 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5460 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5463 * Added status flag to SilcSKE object to indicate realtime status
5464 of the SKE protocol.
5466 * Application receives now exactly same command reply arguments as
5467 the library receives from server. However, if ID is received the
5468 corresponding ID entry is returned to the application (eg. Client
5469 ID is mapped to correct SilcClientEntry entry and that is returned).
5470 Changed command_reply client operation due to this change.
5472 * Changed all ID's in commands and in command replys as ID Payloads.
5473 Change affected both client and server side codes.
5475 All ID's sent in SILC network (with execption of ID's in SILC
5476 Packet header) are sent in ID Payload to support variable length
5479 * Server now notifies nick changes and notifies all clients on
5480 the channels about the new nickname (about the new Client ID,
5483 * Implemented CMODE command to change channel modes. Supports all
5484 channel modes defined by the protocol specs except ban and invite
5485 lists. (Also, private channel key mode is supported but support for
5486 setting private channel key in client is missing, thus, this mode
5487 has no effect on client side (except that server requires that the
5488 client uses private channel key and normal channel traffic does not
5491 Also, invite mode works per se, but INVITE command does not work
5492 yet correctly, so you can set channel as invite only channel but
5493 inviting clients to the channel does not work (it is yet to be
5494 thought what's the best way to do it).
5496 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5497 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5498 Implemented CUMODE command to change user's mode on the channel.
5499 Supports all modes defined by the protocol specs.
5501 * Added NAMES command reply to return users modes on the channel.
5503 * Removed unnecessary and slow ciphers from lib/silccrypt.
5505 * Set SO_KEEPALIVE option to connection sockets by default.
5507 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5509 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5510 redefined the Notify Payload into protocol specs.
5512 * Added silc_id_payload_parse_id to get ID directly from raw
5515 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5518 accept searching by Client ID as well.
5520 * Added support for LEAVE and SIGNOFF notify types in client library.
5522 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5523 to parse ID Payload from raw data.
5525 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added flags parameter into silc_ske_assemble_security_properties
5528 function in lib/silcske/silcske.[ch].
5530 * Changed notify client operation to fit better for notify messages
5531 sent by server. The notify payload received from server is now
5532 passed to the application (after parsing it to SilcNotifyPayload).
5533 It is application's responsibility to retrieve the arguments
5534 from the payload and show the message the way it wants. The message
5535 sent by server is implementation specific.
5537 * Changed public keys to comply with the protocol specification.
5538 Old public keys are not supported anymore and are not compatible.
5540 * Removed nickname from Channel Payload as the latest draft removed
5541 it. The client must resolve the nickname from the NAMES command
5542 reply received when it joined the channel.
5544 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5546 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Fixed some errors in protocol specification drafts.
5550 * Created lib/silccore/silcnotify.c to implement Notify Payload
5551 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5552 generic payloads described by protocol specifications. The file
5553 includes implementations for ID Payload and Argument Payload.
5555 * Changed Command Payload implementation to use the new Argument
5556 Payload. Changed command_xxxx_payload to command_payload_xxxx
5557 to comply with SILC coding conventions.
5559 * Added suppport for Argument Payload handling in Notify Payload
5560 implementation as protocol requires it. Added the new support
5561 into server and client lib as well.
5563 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Added support for multiple nicknames on same channel. [n] is
5566 added locally to the nickname if there are more than one same
5567 nicknames on the channel.
5569 * Server now sends all nicknames that matched WHOIS request.
5570 Client also shows the list received from server.
5572 * Added TOPIC command to client side. User can now set and show
5573 current topic on channel.
5575 * Added MOTD command to client and server. Also, server sends the
5576 motd when client connects to the server.
5578 * Changed version strings to comply ISO 8601.
5580 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Fixed protocol error handling in client library. It should now
5583 cope even if the SKE fails for some reason.
5585 * Made new protocol specification drafts for submitting to IETF.
5587 * Implemented TOPIC command to server in silcd/command.c.
5589 * Added two new notify types into lib/silccore/silcnotify.h:
5590 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5591 notify nickname change and topic setting/change on a channel.
5593 * API change of command_reply operation in client library. The
5594 application gets now the status type received from server as well.
5596 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5600 * Cras fixed and optimized the packet handling even further and
5601 it should work now. Minor change to the prototype of function
5602 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5604 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Added new function into lib/silcutil/silcschedule.[ch]:
5607 silc_schedule_with_fd to select() a specified fd. The function
5608 returns after timeout expires or data arrives or goes. The
5609 function is used by packet routines to wait that all data is
5610 received from network.
5612 * Fixed data reading from network in lib/silccore/silcpacket.c.
5613 The code now assures that all data is read from the fd and then
5614 continues packet processing. This was a bug fix since the code
5615 used to drop some data in some circumstances.
5617 * Added new function into lib/silcclient/client.[ch]:
5618 silc_client_start_key_exchange to start key exchange after
5619 connection has been established to server. The code internally
5620 now uses this funtion but its main purpose was to provide it
5621 for applications that perform their own connecting. After
5622 application has created a connection it merely calls this
5623 function to start the key exchange between client and server.
5624 The library takes care of everything else after that.
5626 Updated also lib/silcclient/README to explain the usage of
5629 * Do not send to application information that connection has
5630 been established. Application gets notified it by connect
5633 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Applied cras's patch to add silc_schedule_one function. The
5636 function runs scheduler once and returns.
5638 * Fixed the scheduler after cras messed it up. The timeout
5639 handling works now as it's supposed to work.
5641 * Added into lib/silccore/ silcnotify.h to include notify
5642 message types support. Changed silc_server_send_notify*
5643 functions, in server.[ch], to support those new notify types.
5644 Added the support for the notify types into client library,
5645 as well. Added new notify client operation into ops.h in
5648 * Changed silc_server_packet_send_to_channel to send normal
5649 packets instead of just channel message packets. The function
5650 is now used to send the notify packets to channels. It is not
5651 used to send channel message packets anymore, as server never
5654 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5655 va_arg()s as it seems to require it nowadays. I guess, if SILC
5656 is compiled with older va_arg() the new code should work anyway.
5658 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Splitted core library. Core library (lib/silccore) includes
5661 now only SILC protocol specific core (and common) components.
5662 Created new utility library (lib/silcutil) that includes more
5663 generic purpose stuff. The stuff for util library was taken
5664 from the old core library. This was minor and easy split.
5666 * Created SILC Client Library (lib/silcclient) that includes
5667 implementation of the SILC client without user interface. This
5668 was major move from silc/ directory. The code has been changed
5669 so that it is transparent towards the user interface. The
5670 silc/ directory includes now the same user interface as before
5671 and it uses the new client library. Read lib/silcclient/README.
5672 Basicly, the client library performs everything else related
5673 to SILC except user interface handling. Also, configuration
5674 files are considered to be part of user interface and library
5675 does not handle them.
5677 This change also changed a lot of structures, function naming etc.
5678 Most important change was that SilcClientWindow object was
5679 renamed to SilcClientConnection in the client library. Created
5680 also new file lib/silcclient/ops.h. Also added new files
5681 silc/local_command.[ch] and silc/client_ops.[ch].
5683 All these changes were made to make it easier for user interface
5684 designers to create what ever user interface for the SILC client
5687 It is also expected that the server will be moved to lib
5688 directory as well and SILC Server Library will be created;
5689 sometimes in the future.
5691 * Removed Local commands from lib/silccore/silccommand.h as
5692 they are application specific and new client library does not
5693 handle any of those anymore.
5695 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5696 old client implementation in silc/.
5698 * Added support for callback functions in SILC_LOG_* macros.
5699 Application can now set its own callbacks that will be called
5700 instead of using the default functions that will always print
5701 the debug messages to stderr (or stdout). Also, debugging can
5702 now be disabled by setting silc_debug to FALSE and re-enabled by
5703 setting it to TRUE. Note, that logging will still work even
5704 if debugging is disabled.
5706 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5707 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5708 silc_log_reset_debug_callbacks.
5710 * To enable debugging in silc client one must give now -d
5711 option on command line.
5713 * Changed silc_schedule_init to automatically allocate task queues
5714 if they are not allocated before calling it.
5716 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Added GMP 3.1 into math library.
5720 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5723 a channel in SILC network. The packet is used by servers and
5724 routers to notify other routers that user has left a channel.
5725 This little feature was missing until now. Added the feature
5726 to protocol specification as well.
5728 Added functions: silc_server_send_remove_channel_user and
5729 silc_server_remove_channel_user into server.[ch].
5731 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5732 lib/silccore/silcpacket.h. However, they are not implemented
5735 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Fixed joining to a channel and sending channel messages
5738 between server and router. The channel message sending should
5739 now work inside a cell.
5741 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Fixed the private message sending between server and router.
5744 The private message sending should now work inside a cell.
5746 * Added silc_server_replace_id into server.[ch] to replace
5747 existing ID in the SILC network.
5749 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5750 and silc_idlist_replace_server_id into idlist.[ch] in server.
5752 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Fixed the server to server connections. Server can again now
5755 connect to router. Router to router connections probably does
5758 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Added dynamic protocol registering support. Now protocols can
5761 registered and unregistered on the fly. Patch by cras.
5763 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Added lib/contrib directory to hold routines that some platforms
5766 don't have but are needed by SILC.
5768 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5769 into lin/contrib to provide getopt() and getopt_long() for
5770 those who don't have it.
5772 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added AWAY command to client. When away message is set and
5775 client receives a private message packet the client automatically
5776 replies to the sender with the away message.
5778 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5779 bug seemed to be the cause of recent problems when compiling
5782 * Added version detection support to SKE protocol specification
5783 and added the new changes to the SKE implementation as well.
5784 There were other minor changes in the SKE protocol as well.
5786 Many changes in lib/silcske/silcske.[ch] and in
5787 lib/silcske/payload.[ch].
5789 * Added ^U functionality, clear input line. Patch from cras.
5791 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Mainly small bugfixes on core library. Fixed some debugging
5794 logging and buffer overflow in silclog.c.
5796 * Updated config.sub and config.guess on the distribution tree.
5798 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added command lagging support in server. Client may execute
5801 commands now only once in two seconds.
5803 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Optimized packet reception. MAC computation and checking is now
5806 also more optimized. A lot previously duplicated code is now
5807 used as generic by both client and server.
5809 * Fixed key pair generation in clientutil.c
5811 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Added into lib/silccore/silcbufutil.[ch] new function;
5814 silc_buffer_realloc.
5816 * Moved generic packet sending/encryption functions to
5817 lib/silccore/silcpacket.[ch] from client and server. Some
5818 rewriting of the functions.
5820 * Moved all generic packet reception/decryption functions to
5821 lib/silccore/silcpacket.[ch] from client and server. The
5822 packet processing is now much cleaner in both client and server.
5823 These were major changes in both client and server.
5825 * Created many common functions in server to do packet sending.
5826 Previously code were duplicated a lot, this has been removed
5829 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Rewrote major parts of the ID cache system. Don't know
5832 whether it is better now or not but at least the API is more
5835 * Major rewrite on ID cache stuff on client because of the ID
5836 cache API changes. Added idlist.c to client.
5838 * Also major rewrite on ID cache stuff on server as well.
5839 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5840 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5841 in hand, instead they are all put into the ID cache system now.
5842 All server_idlist_* routines uses ID cache now instead of
5843 traversing its own lists (those lists does not exist anymore).
5844 SilcIDList though still exists. Also, SilcXXXEntry's are
5847 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Finally made the SKE implementation compliant to the protocol
5850 specification. All mp integers are now binary encoded as
5851 opposed being HEX encoded.
5853 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5856 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5857 functions: silc_[encode/decode]_pem. Also added function
5858 silc_encode_pem_file to PEM encode with newlines ('\n') for
5861 * SILC public keys are now encoded either PEM or binary. Same
5862 option is for private keys as well. By default private keys
5863 are binary encoded and public keys PEM encoded. Silly HEX
5864 encoding were removed.
5866 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5867 function to create fingerprints.
5869 * Fixed a bug in SHA1; does not change the original data anymore.
5871 * Partly implemented INFO command on client and server side.
5872 Fixed CLEAR command. Changes to SERVER command; show current
5873 server(s) when giving command without arguments. Added
5874 VERSION command to client.
5876 * Added check to server that unregistered connections cannot
5877 execute commands (unless it is specificly allowed).
5879 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Fixed screen refresh.
5883 * Fixed channel joining bug from client. On some circumstances
5884 client tried to join to a channel it had already joined.
5886 * Added public key verification process into client's protocol.c.
5887 The client now verifies the public key from user and saves
5888 it into ~./silc/serverkeys/ directory.
5890 Added into: clientutil.[ch]: silc_client_verify_server_key.
5892 * Changed SKE protocol's silc_ske_initiator_finish function
5893 to accept callback function that verifies the received public
5894 key. Removed old silc_ske_verify_public_key function.
5896 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5899 silc_pkcs_private_key[_data]_set.
5901 * Made the password and public authentication more cleaner in
5902 server's protocol.c.
5904 * Removed historic and obsolete protocol `channel_auth' from
5905 both client and server.
5907 * Removed wrong way of sending command status messages from
5908 server to client in server's command.c. The old way violated
5909 protocol specification.
5911 Changes to silccore/silccommand.[ch]: removed
5912 silc_command_encode_status_payload -> not needed anymore,
5913 changed silc_command_encode_payload_va to accept extra
5914 argument on variable argument list. The argument type must
5915 now be provided to the function. Also, added new function:
5916 silc_command_encode_reply_payload_va which is same as
5917 normal command_encode_payload_va except command status type
5918 is provided as extra argument.
5920 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Added ~./silc directory handling. The directory includes the
5923 public and private keys for the client.
5925 Added silc_client_check_silc_dir, silc_client_create_identifier
5926 and silc_client_load_keys.
5928 * Implemented SILC protocol compliant public key. Added public
5929 and private key saving to and loading from files.
5931 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5932 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5933 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5934 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5935 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5937 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5938 silc_pkcs_load_[public/private]_key.
5940 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Added silc_server_get_route (route.[ch]) to get connection
5943 data for the fastest route for given ID.
5945 * Implemented INVITE command on client and server. The command
5946 were re-defined in the SILC Protocol Specification and the
5947 implementation now complies with the specification.
5949 * Implemented PING command on client and server.
5951 * Implemented NAMES command on client and server. The server side
5952 supports currently only normal server not router server yet.
5953 Some changes to NAMES definition in SILC protocol specification.
5955 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Implemented LEAVE command on client and server.
5959 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5960 again. This change was made to the protocol as well. Server
5961 should not violate the protocol specification anymore.

5965 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5966 was tested. SOCKS4 was not but should work anyway.
