1 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Call check_version SKE callback for initiator too. Affected
4 file lib/silcske/silcske.c.
6 * Implemented fix for security hole found in the SKE that was
7 fixed in the specification few days back; the initiator's
8 public key is now added to the HASH value computation.
9 Added backwards support for the old way of doing it too, for
10 old clients and old servers. Affected file is
11 lib/silcske/silcske.c.
13 * Enabled mutual authentication by default in SKE. If initiator
14 is not providing mutual authentication the responder will
15 force it. This will provide the proof of posession of the
16 private key for responder. The affected files are
17 lib/silcclient/protocol.c and silcd/protocol.c.
19 * Do not cache anymore the server's public key during SKE.
20 We do mutual authentication so the proof of posession of
21 private key is done, and if the server is authenticated in
22 conn auth protocol with public key we must have the public
23 key already. Affected file silcd/protocol.c.
25 * Added new global debug variable: silc_debug_hexdump. If
26 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
27 file lib/silcutil/silclog.[ch].
29 * Fixed compilation warning due to char * -> const char *.
30 Affected files lib/silcutil/silcnet.h, and
31 lib/silccore/silcauth.[ch].
33 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
35 * Fixed CMODE command when new channel key was created. If
36 the creation failed the old key was removed. Next time giving
37 same command would crash the server since the old key was
38 freed already. Affected file silcd/command.c.
40 * Fixed the silc_server_announce_get_channels to not crash
41 on reconnect. Affected file silcd/server.c.
43 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Added silc_log_set_debug_string function to set a regex
46 string to match for debug output. Only the function names,
47 or filenames matching the given debug string is actually
48 printed. This way it is possible to filter out those debug
49 strings that user is not interested in.
51 Fixed a bug in silc_string_regexify.
53 Affected files lib/silcutil/silclog.[ch], and
54 lib/silcutil/unix/silcunixutil.c.
56 * Changed the -d options in both server and Irssi SILC client
57 to take the debug string as argument. Affected files
58 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
60 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Added silc_hash_babbleprint to create a Bubble Babble
63 Encoded fingerprint. The encoding is developed by Antti
64 Huima (draft-huima-babble-01.txt), and it creates human
65 readable strings out of binary data. Affected file
66 lib/silccrypt/silchash.[ch].
68 * Print the babble print now in addition of fingerprint as well
69 in Irssi SILC client. Affected files are
70 irssi/src/fe-common/silc/module-formats.[ch],
71 irssi/src/fe-common/silc/core/client_ops.c.
73 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed a security problem found in SKE. The initiator's
76 public key too is now added to the HASH hash value creation
77 which is signed by the responder to create the SIGN value.
78 This will prevent anyone in the middle to lie to the responder
79 about the initiator's public key. If this is done now, the
80 man in the middle will get caught. Updated the protocol
83 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Better installation directory handling. Configure module
86 paths and other paths automatically to example_silc* files
87 in doc/. A patch by toma.
89 * Fixed compiler warning from MPI library, and from SILC RNG.
92 * Added SILC_SERVER_PID_FILE to define the pid file for server.
93 It can be configured with ./configure. A patch by toma.
95 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Find correct make to use in prepare-clean. A patch by
98 toma. Affected file prepare-clean.
100 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
102 * Added irssi variables use_auto_addr, auto_bind_ip,
103 auto_bind_port and auto_public_ip.
105 * Changed the interface for silc_client_send_key_agreement
106 in lib/silcclient/silcapi.h
110 irssi/src/silc/core/silc-core.c
112 lib/silcclient/silcapi.h
113 irssi/src/silc/core/silc-channels.c
114 lib/silcclient/client_keyagr.c
117 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Added silc_pkcs_public_key_compare to compare two
120 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
122 * Check that the client who set the founder mode on the
123 channel is the same client that is giving the founder
124 mode to itself. It is done by comparing the saved public
125 key (it is saved even in the authentication is passphrase).
126 Affected file silcd/command.c.
128 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Do not process packet for disconnected socket connection.
131 Affected file lib/silccore/silcpacket.c.
133 * Process the DISCONNECT packet through scheduler in the
134 client library. Affected file lib/silcclient/client.c.
136 * Fixed the silc_client_packet_parse to not to increase
137 the packet sequence number if the conn->sock and the
138 current socket connection is not same. This can happen
139 for example during key agreement when the conn includes
140 multiple socket connections (listeners). Affected file
141 lib/silcclient/client.c.
143 * The sender of the file transfer request now provides also
144 the pointer (listener) for the key exchange protocol. If
145 the listener cannot be created then it sends empty key
146 agreement and lets the receiver provide the listener.
148 Added `local_ip' and `local_port' arguments to the
149 silc_client_file_send. If they are provided they are used,
150 if not then it will attempt to find local IP address, if
151 not found or bind fails then the remote client will provide
154 Affected files are lib/silcclient/client_ftp.c and
155 lib/silcclient/silcapi.h.
157 * Extended the FILE SEND command to support defining the
158 local IP and port for key exchange listener. They are
159 optional. Affected file irssi/src/silc/core/silc-servers.c.
161 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
163 * Defined to WHOIS command reply the sending of fingerprint
164 of the client's public key (if the proof of posession of the
165 corresponding private key is verified by the server).
166 Updated to the protocol specification.
168 * Added support of receiving the client's public key's
169 fingerprint in command reply in client library. Affected
170 file is lib/silcclient/command_reply.c, and
171 lib/silcclient/idlist.[ch].
173 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
175 * Do not send over 128 chars long nickname to the server
176 in NICK command. Affected file lib/silcclient/command.c.
178 * Do not send over 256 chars long channel names to the server
179 in JOIN command. Affected file lib/silcclient/command.c.
181 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
183 * Assure that silc_server_close_connection cannot be called
184 twice for same socket context. Affected file is
187 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
189 * Send error message to application if opening file for
190 writing during file transfer fails. Affected file is
191 lib/silcclient/client_ftp.c.
193 Remove all file transfer sessions for a client that we're
194 removing from ID cache.
196 Affected file is lib/silcclient/client_ftp.c.
198 * Fixed silc_net_addr2bin to return correct address. Affected
199 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
201 * Fixed file transfer session removing on signoff notify.
202 Affected file irssi/src/silc/core/silc-servers.c.
204 * Added the SilcClientFileError to be returned in the monitor
205 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
206 Affected file lib/silcclient/silcapi.h.
208 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
210 * Fixed a crash in silc_client_ftp_free_sessions and
211 silc_client_ftp_session_free_client. Affected file
212 lib/silcclient/client_ftp.c.
214 * Added `disabled' field in the SilcChannelEntry in the server
215 to indicate if the server entry is disabled. Affected file
216 silcd/idlist.h, silcd/command[_reply].c.
218 * SILC server adds now /var/run/silcd.pid everytime it is
219 started. Affected file silcd/silcd.c.
221 * Added silc_server_packet_send_clients to send a packet to
222 the provided table of client entries. Affected file
223 silcd/packet_send.[ch].
225 * Fixed a crash in client resolving in client_prvmsg.c in
226 client library. Affected file lib/silcclient/client_prvmsg.c.
228 * Do not actually remove the client directly from ID cache
229 during SERVER_SIGNOFF, but invalidate it. This way we
230 preserve the WHOWAS info for the client. Affected file
233 * Fixed SERVER_SIGNOFF notify handling in the server. The
234 server is now able to process incoming SERVER_SIGNOFF notify
235 for a server that it doesn't even know about. It will remove
236 the clients provided in the notify. Affected file
237 silcd/packet_receive.c.
239 * Check for partial packet in data queue after every packet that
240 was found from the queue. Return and wait for more data if
241 there is partial data in queue. Affected file is
242 lib/silccore/silcpacket.c.
244 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
246 * Added SilcClietFileError enum to indicate error in
247 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
248 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
249 Affected files lib/silcclient/silcapi.h and
250 lib/silcclient/client_ftp.c.
252 * Check that newsize in silc_buffer_realloc is larger than
253 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
255 * Added better monitor of file transfers. It now monitors
256 key agreement protocol during the file transfer too. Added
257 error reporting too. Affected files
258 irssi/src/silc/core/silc-servers.c,
259 irssi/src/fe-common/silc/module-formats.[ch].
261 * Wrote a help file for FILE command.
263 * Added silc_rng_global_get_byte_fast to get not-so-secure
264 random data as fast as possible. Random data is read from
265 /dev/urandom if available and from the SILC RNG if not
266 available. It is used in padding generation. Affected file
267 lib/silccrypt/silcrng.[ch].
269 * All packets in client library are now processed synchronously.
270 Optimized packet processing a lot. Affected file
271 lib/silcclient/client.c.
273 * All server connection packets are processing synchronously
274 now in server, to optimize packet processing. Affected file
277 * Include files are installed now only in Toolkit distribution
278 if make install is given. Affected files: all Makefile.am's.
280 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
282 * Assure that silc_client_notify_by_server_resolve does not
283 resolve the client information multiple times. If it cannot
284 be found by the first it cannot be found at all. Affected
285 file lib/silcclient/client_notify.c.
287 * Fixed WHOWAS command reply calling. Affected file
288 lib/silcclient/command_reply.c.
290 * Removed all references to silc_idlist_get_client from the
291 Irssi SILC client since that call is internal call used by
292 the library. The Irssi SILC client will use now client
293 retrieval functions found in silcapi.h.
295 * Fixed a bug in resolving nickname info before sending
296 private message. It used freed memory. Affected file
297 irssi/src/silc/core/silc-servers.c.
299 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
301 * Assure my_channels statistics cannot go negative in server.
302 Affected files silcd/server.c, silcd/server_util.c.

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

340 Added preliminary support for simple client to client one-file
341 transmission. Affected file lib/silcclient/client_ftp.c,
342 lib/silccilent/client.[ch].
344 * Added new local command FILE to the Irssi SILC Client.
345 It is used to perform the file transfer. It has subcommands
346 SEND, RECEIVE, SHOW and CLOSE. Affected files
347 irssi/src/silc/core/client_ops.c,
348 irssi/src/silc/core/silc-server.[ch].

360 lib/silcutil/silcutil.[ch].
362 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
364 * Resolve the client info when received private message or
365 channel message for a client which nickname we don't know.
366 Affected files lib/silcclient/client_prvmsg.c and
367 lib/silcclient/client_channel.c.
369 * Do not crash in /KEY if client is not connected. Affected
370 file irssi/src/silc/core/silc-channels.c.
372 * Added SilcClientStatus field to the SilcClientEntry in the
373 lib/silcclient/idlist.h.
375 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
376 is incomplete and is being resolved, it won't be resolved
379 Make sure also that USERS command reply does not resolve
380 twice information. Affected file is
381 lib/silcclient/command_reply.c.
383 Make sure that silc_client_get_clients_by_list does not
384 resolve twice same information.
386 * Check for valid client->id in the silc_server_free_client_data.
387 Affected file silcd/server.c.
389 * Fixed /GETKEY nick@server not to crash if the server entry
390 is not found. Affected file lib/silcclient/command.c.
392 * Fixed the silc_server_check_cmode_rights to check the
393 requested modes correctly. Affected file silcd/command.c.

397 * Better checks for non-printable chars in nick added.
398 Affected file silcd/command.c.
400 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Call the silc_server_udpate_servers_by_server in the
403 primary router that comes back online in the backup resuming
404 protocol. Otherwise it routes packets wrong. Affected file
405 silcd/server_util.[ch], silcd/server_backup.c.
407 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
409 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
410 lib/silcutil/silcbuffmt.[ch].
412 * Redefined the SILC packet header to include the padding
413 length. Affected file lib/silccore/silcpacket.[ch].
415 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
416 length for maximum padding up to 128 bytes). Affected
417 file lib/silccore/silcpacket.h.
419 * Removed all backwards support for old 0.5.x MAC thingies.
420 The SILC packet header change makes it impossible to be
421 backwards compatible.
423 * Send the ENDING packet with timeout in the backup resuming
424 protocol. This is to assure that all routers has connected
425 to the primary router. Affected file silcd/server_backup.c.
427 * Changed the RNG to take the first IV from random data. It
428 used to take it from zero actually. Changed the RNG also
429 to use /dev/urandom during session. /dev/random is used
430 in initialization. Affected file lib/silccrypt/silcrng.[ch].
432 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
434 * Changed the SILC packet header to have the first two bytes
435 (the packet length) encrypted. Affected files aroung the
436 code tree, lib/silccore/silcpacket.[ch]. Removed the
437 SilcPacketCheckDecrypt callback. It is not needed anymore
438 since the silc_packet_receive_process will determine now
439 whether the packet is normal or special.
441 * Implemented the unidirectional MAC keys. Affected files
442 lib/silcske/silcske.c, silcd/protocol.c and
443 lib/silcclient/protocol.c.
445 * Implemented the packet sequence number to the MAC computation.
446 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
447 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
448 lib/silcclient/protocol.c.
450 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Allow backup router to announce servers. All servers
453 announced by backup router are added to the global list
454 automatically. Update hte server's socket to our primary
455 router also when backup router announces a server.
456 Affected file silcd/packet_receive.c.
458 * Do not update the client->router in the function
459 silc_server_udpate_clients_by_server if the client is on
460 global list. We might fail to find any specific server
461 for locally connected clients and local cell clients. They
462 should still use the `from' and not `to' as client->router.
463 This fixes backup router resuming protocol. Affected file
466 * Decrease channel statistics count only if the channel
467 deletion worked. Affected files are silcd/server.c and
470 * Added silc_server_update_servers_by_server to update origin
471 of all server entries. Used during backup router protocol.
472 Affected files silcd/server_util.[ch], silcd/server.c. and
473 silcd/backup_router.c.
475 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
476 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
477 silc_hmac_get_hash and silc_hmac_get_name. Affected file
478 lib/silccrypt/silchmac.c.
480 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Assure that router cannot reroute the same channel message
483 to the sender. Affected file silcd/packet_receive.c.
485 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
487 * Made better checks that the channel message is not sent
488 to the router it came from. Affected file is
489 silcd/packet_send.c. Fixed memory leak too.
491 * Announce informations for incoming router connection, but
492 only after checking if it is replaced by backup router.
493 Affected file silcd/packet_receive.c.
495 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
497 * Fixed the backup resuming protocol to work in multiple
498 router environment. Affected file silcd/server_backup.c.
500 * Route packet only to one router in the function
501 silc_server_packet_send_to_channel. Affected file is
504 * Fixed silc_server_send_notify_dest to set the broadcast
505 flag. Fixed the silc_server_send_notify_topic to actually
506 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
507 Affected file silcd/packet_send.c.
509 * Changed the SFTP Filesystem interface. Changed the
510 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
511 the filesystem operation function. The SilcSFTPFilesystem
512 is now a context that is allocated by all filesystem allocation
513 functions and it already includes the operations structure
514 and filesystem specific context. It is given as argument
515 now to the silc_sftp_server_start. This made the interface
516 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
517 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
519 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
521 * Changed the backup router adding and getting interfaces
522 in the server. The router that will be replaced by the
523 specified backup router is now sent as argument. Affected
524 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
527 * Added silc_net_addr2bin_ne to return the binary form of
528 the IP address in network byte order. Affected files
529 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
531 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
533 * Check for existing server ID in silc_server_new_server
534 and in silc_server_connect_to_router_final and remove the
535 old entry if it exists. Affected file silcd/packet_receive.c,
538 * Send the channel message always to only one router, either
539 in upstream or downstream. Affected file is
542 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Wrote the definition of the backup resuming protocol to the
545 protocol specification.
547 * Removed one redundant channel key generation from normal
548 server during joining procedure. Removed one redundant
549 channel key sending from server to router during joining
550 procedure. Affected file silcd/command.c.
552 * Made minor bugfixes to the backup router resuming protocol.
553 Affected file silcd/server_backup.c, server.c.
555 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Added --disable-asm configuration option. Affected files
558 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
561 * Implemented the backup resuming protocol that is used to
562 resume the primary router position in the cell after the
563 primary router comes back online. Affected files
564 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
565 and silcd/server_util.[ch].
567 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Sleep two (2) seconds after sending QUIT command to server.
570 Affected file lib/silcclient/command.c.
572 * Assure that if outgoing data buffer is pending do not force
573 send any data. Affected file silcd/packet_send.c.
575 * Assure that if outgoing data buffer is pending do not force
576 send any data. Affected file lib/silcclient/client.c.
578 * Implemented the backup router support when the primary router
579 goes down. The servers and routers can now use the backup
580 router as new primary router without loosing connectivity.
582 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
584 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
585 in the server to indicate disabled entry. All data read
586 from the connection will be ignored and no data is sent
587 for entry that is disabled. Affected files are
588 silcd/idlist.h, silcd/server.c.
590 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Created SFTP client and server test programs in the
593 lib/silcsftp/tests directory.
595 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
597 * Implemented memory filesystem (virtual filesystem) for
598 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
601 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Implemented the SFTP (SSH File Transfer Protocol) to the
604 lib/silcsftp. It includes SFTP client and SFTP server
607 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Moved lib/silccore/silcprotocol.[ch] to the
610 lib/silcutil library.
612 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
613 take variable argument list pointer as argument. Affected
614 file lib/silcutil/silcbuffmt.[ch].
616 * Added silc_buffer_set function that is used to set data
617 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
618 Affected file lib/silcutil/silcbuffer.h.
620 * Changed various routines in the core library to use the new
621 silc_buffer_set instead of allocating new buffer only for
624 * Added 64-bit value formatting and unformatting support to the
625 silc_buffer_[un]format routines. Affected file is
626 lib/silcutil/silcbuffmt.[ch].
628 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
629 to includes/bitmove.h.
631 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed channel user mode saving in client library. Affected
634 file lib/silcclient/command[_reply].c.
636 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
638 * Defined the file transfer to the SILC Protocol. Added
639 new packet type SILC_PACKET_FTP and defined File Transfer
640 Payload. The mandatory file transfer protocol is SFTP
641 (SSH File Transfer Protocol). Affected file in addition
642 of the internet draft is lib/silccore/silcpacket.h.
644 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
645 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
646 is used as part of backup router protocol when the primary
647 router of the cell is back online and wishes to resume
648 the position as primary router.
650 * Redefined the MAC generation keys in the protocol. The
651 same key is not used anymore in both direction. Both
652 direction will now use different keys for sending and
653 receiving. This fixes a potential security flaw. This
654 change causes incompatibilities in the protocol.
656 * Redefined also the MAC computation from the packet.
657 An packet sequence number is now added to the MAC
658 computation. This prevents possible replay attacks against
659 the protocol. This change too causes incompatibilities
662 Added `sequence' field to the SilcPacketContext to hold
663 the current sequence number for the packet.
665 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Added `created' field to the SilcIDListData in the file
668 silcd/idlist.h to indicate the time when the entry was
671 * Added `created' field to the SilcChannelEntry too. Affected
674 * Added `creation_time' aguments to all the announcement functions
675 in the server. If it is provided then only the entries that
676 was created after the provided time frame are actually
677 announced. Affected file silcd/server.[ch].
679 * The protocol says that the Channel ID's IP address must be
680 based on the router's IP address. Added check for this in
681 the silc_server_new_channel when processing incoming New Channel
682 Payload. Affected file silcd/packet_receive.c.
684 * Print out the correct version with --version in SILC client.
685 Affected file irssi/src/silc/core/silc-core.c.
687 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Fixed WHOWAS command to check for completnes of the client
690 entry always, not just when the command is coming from client.
691 Affected file silcd/command.c.
693 * Added new function silc_server_packet_queue_purge to purge the
694 outgoing data queue to the network. After the function returns
695 it is guaranteed that the outgoing packet queue is empty.
696 Affected file silcd/packet_send.[ch].
698 * Purge the outgoing packet queue in the rekey protocol's final
699 callback to assure that all rekey packets go to the network
700 before quitting the protocol. Affected file silcd/server.c.
702 * Added silc_client_packet_queue_parse as similar function as
703 in server to the client library. The affected file is
704 lib/silcclient/client.c.
706 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
708 * Splitted silcd/server.c and created silcd/server_util.[ch]
709 for utility functions.
711 * Added new socket flag SILC_SF_DISABLED to indicate that the
712 connection is open but nothing can be sent to or received from
713 the connection. Affected file lib/silcutil/silsockconn.[ch].
714 The checking for disabled socket is checked in the low level
715 silc_socket_write and silc_socket_read functions.
717 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
719 * Allow only nicknames and channel names that fits into the
720 7-bit unsigned char ASCII set. Affected file silcd/command.c.
722 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
724 * When processing JOIN command reply in server check that if
725 the channel exists in our global list we'll move it the local
726 list. Affected file silcd/command_reply.c.
728 * Fixed the check whether client is joined on the channel already
729 in JOIN command. Affected file lib/silcclient/command.c.
731 * Fixed the JOIN command reply to check whether the channel
732 already exists. Affected file lib/silcclient/command_reply.c.
734 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
736 * Added silc_ske_status_string to map the SKE error numbers
737 to readable strings. The affected files are
738 lib/silcske/silcske[_status].[ch].
740 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
742 * Do not show the private channels on the WHOIS channel list
743 as it is not allowed by the protocol. The affected file is
746 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
748 * Assure that the packet length digged from the actual packet
749 is something sensible in the silc_packet_decrypt_rest_special
750 in lib/silccrypt/silcpacket.c.
752 * Free and NULL the allocated pointer in silc_hmac_alloc if
753 the HMAC allocation fails. The affected file is
754 lib/silccrypt/silchmac.c.
756 * Print the selected security properties to the log files in
757 the server. Affected file silcd/protocol.c.
759 * Add SKE's reference counter even if calling the completion
760 callback manually. Otherwise it goes negative, although it
761 does not cause any problems. The affected file is
762 lib/silcske/silcske.c.
764 * Remove the client entry with short timeout after giving the
765 KILL command. Affected file lib/silcclient/command.c.
767 * Fixed to send error reply in WHOIS and IDENTIFY commands in
768 case all found clients are already disconnected (WHOWAS would
769 found them) in the server. Affected file silcd/command.c.
771 * Update the last_receive (time of last data received) to be
772 updated only when received private or channel message so that
773 the idle time showed in WHOIS makes more sense.
775 * Added boolean field `valid' in to the SilcClientEntry in the
776 client library to indicate whether the entry is valid or not.
777 This fixes the nickname change bug on channel when changing
778 the nickname to be same than the old (like nick to Nick) the
779 nickname formatter doesn't set the new nick anymore to Nick@host.
780 Affected file lib/silcclient/idlist.[ch].
782 * Now actually fixed the nickname changing on disconnection.
783 Added new function silc_change_nick to the Irssi SILC Client.
784 Affected file irssi/src/silc/core/client_ops.c,
785 irssi/src/silc/core/silc-nicklist.[ch].
787 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Check that the public key exists in the GETKEY command before
790 trying to encode it. Affected file silcd/command.c.
792 * Print some notifications on received public keys with GETKEY
793 command in the Irssi SILC Client. Affected files are
794 irssi/src/fe-common/silc/module-formats.[ch],
795 irssi/src/silc/core/client_ops.c.
797 * Use IDENTIFY command to resolve the server information in the
798 GETKEY command instead of INFO command. Affected file
799 lib/silcclient/command.c.
801 * All command reply functions in the client library now calls
802 the pending command reply callbacks even if an error has
803 occurred. The server has done this a long time and now it was
804 time to move the client library to this as well. Now all
805 errors can be delivered back to the pending command reply
806 callbacks if necessary. Affected files are
807 lib/silcclient/command[_reply].[ch].
809 * Change the nickname on disconnection back to the username
810 because in reconnect the server will enforce it to it anyway.
811 Affected file irssi/src/silc/core/silc-servers.c.
813 * Fixed a config file parsing bug in the Irssi SILC client.
814 Affected file irssi/src/silc/core/clientconfig.c.
816 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
818 * When printing the channel mode on JOIN, verify that the
819 channel key and channel's HMAC are valid. Affected file
820 irssi/src/silc/core/client_ops.c.
822 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
825 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
826 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
828 * Removed channel key rekey task deleting from the function
829 silc_server_save_channel_key. Affected file silcd/server.c.
830 Added explicit timeout task context instead that is used to
831 delete the task if we are registering a new task before the
832 new task has elapsed.
834 * When channel key rekey occurs the client library now saves
835 the old channel key for a short period of time (10 seconds) and
836 is able to use it in case some is still sending channel
837 messages encrypted with the old key after the rekey. Affected
838 file lib/silcclient/[idlist.h|client_channel.c].
840 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
842 * Added check to the silc_server_new_id_real to not accept
843 new ID if it is the sender's own ID. Affected file is
844 silcd/packet_receive.c.
846 * Assure that we do not announce ourself or the one we've
847 sending our announcements when we're router and are announcing
848 servers to our primary router. Affected file silcd/server.c.
850 * Fixed silc_server_command_identify_check_client to assemble
851 correct WHOIS packet. It send corrupted WHOIS packet and
852 caused problem with router to router connections. Affected
853 file silcd/command.c.
855 Fixed also silc_server_command_whois_check the same way
856 as for the IDENTIFY command.
858 * Added new SilcIDListStatus to the server in the SilcIDListData
859 structure. The status now includes the current status of
860 the entry (like registered, resolved etc.). Affected file
861 silcd/idlist.[ch]. Defined a bunch of different status types
862 as well. This replaced the old boolean registered field as well.
864 Added resolve_cmd_ident field to the SilcClientEntry structure
865 too so that if the entry is for example being resolved so
866 another command may attach to the same pending command reply
867 without requiring to resolve the same entry again. This concept
868 should optimize the WHOIS and the IDENTIFY resolving under
869 heavy load by taking away unnecessary resolving for entries
870 that are being resolved already.
872 Added support for adding multiple pending commands for one
873 command idenfier. Affected file silcd/command[_reply].[ch].
875 * Fixed WHOIS and IDENTIFY save to remove the cache entry
876 before deleting the data. Otherwise the hash table will have
877 freed data in comparison functions. Affected file is
878 silcd/command_reply.c.
880 * Fixed silc_idlist_replace_client_id to add the new entry to
881 the cache with NULL nickname. Otherwise there will be invalid
882 memory as the nickname after the nickname is freed. Affected
883 file silcd/packet_receive.c.
885 * Fixed the silc_idlist_get_clients_by_hash. The entries was
886 saved into wrong slots because the previous number of entries
887 was not taken into account. Affected file silcd/idlist.c.
888 Fixed same thing in silc_idlist_get_clients_by_nickname too.
890 * If we are router and we receive JOIN notify to a channel that
891 does not have any users then notified client is marked as the
892 channel founder, as it is it. The affected file is
893 silcd/packet_receive.c
895 * Added to the extended hash table API's table_del_*ext functions
896 the destructor as argument too, so that the caller can decide
897 which destructor to use or whether to use destructor at all.
898 Affected file lib/silcutil/silchashtable.[ch].
900 * Fixed ID Cache purging. It actually deleted the entries from
901 the hash table after the data was freed. The hash table ended
902 up comparing freed memory. The affected file is
903 lib/silccore/silcidcache.c.
905 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Fixed Irssi SILC client's KILL command's HELP syntax.
909 * The USERS command now resolves the detailed user information
910 if the userinfo field is missing. Affected file is
911 lib/silcclient/command_reply.c.
913 * Do not print error in silc_file_read if the read file does
914 not exist. Just silently return NULL. Affected file is
915 lib/silcutil/silcutil.c.
917 * Fixed the silc_log_output to not wine about NULL filename
918 and to not create some bogus " " filename. Affected file is
919 lib/silcutil/silclog.c.
921 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
923 * Fixed various printing bugs on the user interface in the
924 Irssi SILC Client. Minor changes that were forgotten from
927 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Fixed the configure.in.pre and the compilation and distribution
930 environment to support the new autoconf 2.52. That version is
931 now required to compile the CVS trunk.
933 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Renamed function silc_parse_nickname to silc_parse_userfqdn
936 to generally parse user@fqdn format strings. Affected file
937 lib/silcutil/silcutil.c.
939 * Added nickname_format and nickname_force_format fields to the
940 SilcClientParams structure. The first one defines the format
941 for the nicknames that the library will enforce if the receives
942 multiple same nicknames. The second one is boolean value and
943 can be used to force the library to always enforce the format
944 to the nicknames regardles whether there are multiple nicknames
945 or not. This configurable formatting was employed to flexibly
946 support accessing multiple nicknames from the user interface.
947 The userinterface can now set the nicknames to what ever format
948 they prefer. Affected file lib/silcclient/silcapi.h.
950 Added function silc_client_nickname_format to the file
951 lib/silcclient/idlist.c. It performs the nickname formatting.
953 Added new field `hostname´ to the SilcClientEntry context.
954 It holds the hostname of the client. Affected file is
955 lib/silcclient/idlist.h.
957 * Irssi SILC Client sets the nicknames in nick@hostn format.
958 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
959 irssi/src/silc/core/silc-core.c.
961 The WHOIS printing now also shows both the real nickname and
962 the formatted nickname so that user knows how to access the
963 user if there are multiple same nicknames cached. Affected
964 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
965 printing formatting too to take the hostname now as a separate
966 argument. The Affected file is
967 irssi/src/fe-common/silc/modules-formats.[ch].
969 * Changed the silc_client_get_clients_local to accept the formatted
970 nickname as argument. It accepts the real nickname too but the
971 formatted nickname can be used to find the true entry from
972 multiple entries. Affected file lib/silcclient/silcapi.h and
973 lib/silcclient/idlist.c.
975 * Added nickname_format_parse field to the SilcClientParams.
976 It is a callback function provided by the application to parse
977 the nickname out of the formatted nickname string. The library
978 calls it to get the nickname from the formatted string. Since
979 the application generally knows better the format of the nickname
980 string it parses it instead of the library, even though library
981 encodes the formatted string. If the callback function is not
982 provided then the library will use the string as is. The
983 affected file is lib/silcclient/silcapi.h.
985 * All the nickname strings passed to the client library in
986 commands are now expected to be formatted nickname strings.
987 If the command does not support the formatted nickname string
988 it will assume that the sent string is the actual nickname.
989 Affected file lib/silcclient/command.c.
991 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Added public key authentication support to OPER and SILCOPER
994 commands in the client library. Affected file is
995 lib/silcclient/command.c.
997 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Changed the get_auth_methdod client operation to be asynchronous.
1000 It can be async if the application resolves the authentication
1001 method from the server during the negotiation. Added new
1002 SilcGetAuthMeth completion callback that the application will
1003 call after resolving the authentication method.
1005 Added function silc_client_request_authentication_method that
1006 the application can use to resolve the authentication method
1007 from the server. Added also SilcConnectionAuthRequest callback
1008 that the library will call after the server has replied. The
1009 application can call this function if it does not know the
1010 current authentication method.
1012 Affected files are lib/silcclient/client.c and
1013 lib/silcclient/silcapi.h.
1015 * The Irssi SILC client now automatically resolves the authentication
1016 method incase any configuration information is not present (and
1017 currently there never is). The affected file is
1018 irssi/src/silc/core/client_ops.c.
1020 * Fixed public key authentication from the client library.
1021 Affected file lib/silcclient/protocol.c. Changed also the
1022 protocol specification about the public key authentication in
1023 the connection authentication protocol. The actual data to be
1024 signed is now computed with a hash function before signing.
1026 * Fixed the public key authentication from the server as well.
1027 Affected file silcd/protocol.c.
1029 * Removed the mlock()'s from the memory allocation routines.
1030 Affected file lib/silcutil/silcmemory.c. The ./configure does
1031 not check anymore for the mlock(). Affected file is
1034 * Fixed USERS command in server to allow the execution of the
1035 command for private and secret channels if the client sending
1036 the command is on the channel. Affected file silcd/command.c.
1038 * Fixed silc_client_get_clients_local to return the clients
1039 count correctly. It could return wrong value. Affected file
1040 lib/silcclient/idlist.c.
1042 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1045 types. The assembler optimizations seemed not to like 64-bit
1046 data types. The assmebler optimizations thus are now enabled
1047 also for BSD systems as opposed to only enable them for Linux.
1049 * Do not check for threads at all on BSD systems. Affected
1050 file configure.in.pre.
1052 * Removed -n and -h options from the Irssi SILC Client since
1053 they are not used in silc.
1055 * Fixed the prime generation to assure that the first digit
1056 of the generated random number is not zero since our conversion
1057 routines does not like number strings that starts with zero
1058 digit. If zero digit is seen the random number is regenerated.
1059 This caused some corrupted RSA keys when the zero first digit
1060 was met. Affected file lib/silcmath/silcprimegen.c.
1062 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Fixed WIN32 configuration in the ./configure script.
1065 Fixed to include xti.h on environments that has it.
1066 Patches by Carsten Ilchmann and andrew.
1068 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Changed the silc_id_create_client_id to be collision
1071 resistant. It is now assured that there cannot be created
1072 two same client ID's. I suspect that some weird bugs in
1073 the server were actually caused by duplicate Client IDs.
1074 Affected file silcd/serverid.[ch]. A router receiving
1075 new ID now also assures and informs the sending server
1076 if the ID caused collision.
1078 * Changed the silc_id_create_channel_id to also assure that
1079 there are no collisions.
1081 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * Statement about ignoring the Mutual Authentication flag when
1084 performing rekey with PFS was a bit misleading. It is ignored
1085 if it was set in the initial negotiation, it cannot be even
1086 set in the rekey. Fixed in the ke-auth draft. Started the
1087 new versions of the protocol drafts in the doc/.
1089 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Fixed a bug in silc_client_command_identify_save when saving
1092 new channel information. The channel name was no duplicated
1093 and caused crash on exit. Affected file is
1094 lib/silcclient/command_reply.c.
1096 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Fixed the getkey command handling in the server. Send just
1099 empty OK reply to the sender if the key could not be fetched
1100 (but everything else was ok, like the key just was not available).
1101 Changed the public key parameter to optional in the protocol
1102 specs so that empty OK reply can be sent. Affected file
1105 Added a message to Irssi SILC client to tell to user if the
1106 server did not return a public key.
1108 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1110 * Fixed a channel key regeneration bug. It registered new
1111 timeout tasks exponentially until all system resources were
1112 used. Affected file silcd/server.c.
1114 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Added the SILC Document generator to the scripts/silcdoc.
1117 It can be used to generate the Toolkit Reference Manual out
1118 of the source tree. Internally it will also use the RoboDoc
1119 generator now imported in util/robodoc.
1121 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Added couple of return's in rekey protocol if error orccurred
1124 during the protocol. The execution must be terminated.
1125 Affected file silcd/protocol.c. Also, terminate the protocol
1126 always with timeout.
1128 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * The client's Client ID was created initally from the wrong
1131 nickname (it could have been in format nick@host) in the
1132 silc_server_new_client. Affected file silcd/packet_receive.c
1134 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1136 * Added some SILC_LOG_ERROR's to various error conditions
1137 if client could not be added to ID cache. Affected files
1138 silcd/packet_receive.c and silcd/server.c.
1140 * When client's sock->user_data is freed, NULL also the
1141 client->router and client->connection pointers. Added check
1142 for these pointers being NULL to various places around the
1143 code. Affected file silcd/server.c.
1145 * Added client->data.registered == TRUE checks to various
1146 places around the code to assure that unregistered client's
1147 are not handled when it is not allowed. Affected file
1150 * Added `bool registered' fields to all
1151 silc_idlist_[server|client]_get_* routines to indicate whether
1152 the fetched client needs to be registered or not. Affected
1153 file silcd/idlist.[ch].
1155 * Add your own entry as registered to the ID cache in the
1156 server. Affected file server.c.
1158 * Fixed a bug in silc_server_new_server. The SilcServer was
1159 set as the new server's context instead of SilcServerEntry.
1160 This naturally caused some weird bugs.
1162 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1164 * Do not delete the channel rekey task when adding it
1165 for in silc_server_create_channel_key.
1167 * Changed the silc_server_create_channel_key to return
1168 TRUE or FALSE to indicate the success of the channel key
1171 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * Fixed MSVC++ project files and added missing files to

1176 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Do not add TCP_NODELAY flag if the operating system
1179 does not have it defined. Affected files are
1180 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1182 * Fixed buffer overflow from Irssi SILC Client. Affected
1183 file irssi/src/fe-common/core/themes.c.
1185 * Fixed double free in client library in the file
1186 lib/silcclient/client.c when disconnecting from server.
1188 * Applied double free patch from cras to Irssi SILC client.
1189 Affected files irssi/src/core/[modules/expandos].c
1191 * Fixed the disconnection handling to Irssi SILC Client.
1192 The application must call silc_client_close_connection
1193 in ops->connect client operation in case of failure of
1194 the connection. Affected file is
1195 irssi/src/silc/core/client_ops.c.
1197 * Do not set sock->protocol to NULL in the function
1198 silc_client_close_connection after executing the protocol's
1199 final callback since the sock might not be valid anymore.
1200 Affected file lib/silcclient/client.c.
1202 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Do not enable SILC_THREADS if the linking with libpthread
1205 did not happen. Affected file configure.in.pre.
1207 * Added notion to protocol specification that server must
1208 verify the sent authentication payload with CMODE when
1209 setting the channel founder key. Implemented it to the
1210 server. Affected file silcd/command.c.
1212 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1214 * Added _EXTRA_DIST SILC distribution variable to the
1215 distributions file. It is used to conditionally add extra
1216 files or directories to the specific distribution. Affected
1217 files ./prepare, Makefile.am.pre and distributions.
1219 Removed the `_' from the start of the distribution names.
1222 * Added README.WIN32 for instructions to compile the Toolkit
1225 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1227 * Fixed a double free in disconnection in the server. Affected
1228 file is silcd/server.c.
1230 * Fixed the lib/silcske/groups.c to work now also with GMP
1231 MP library. The string conversion did not work when using
1232 specific base and the base is indicated in the string as well.
1234 * Created win32/ directory which now includes MSVC++ specific
1235 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1236 It will appear only in the toolkit distribution
1238 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Changed the key material distribution function in case when
1241 the hash output is too short. The data is now concatenated
1242 a bit differently than it used to. Made the change to the
1243 SKE protocol specification.
1245 * Added better GMP detection to configure.in.pre. A patch
1248 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Fixed a minor bug in SKE that might cause some problem on
1251 some platforms. Affected file lib/silcske/silcske.c.
1253 * Added the cookie checking for initiator in the SKE. It checks
1254 that the responder returns the sent cookie unmodified. The
1255 affected file is lib/silcske/silcske.c. Added new SKE
1256 error type INVALID_COOKIE that can be sent during the
1257 negotiation. Fixed some memory leaks as well.
1259 * Added the "invalid cookie" error message to Irssi SILC client's
1262 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1264 * Added `task_max' field to the SilcClientParams to indicate
1265 the maximum tasks the scheduler can handle. If set to zero,
1266 default values are used. Affected file lib/silcclient/silcapi.h.
1268 * Fixed memory leaks in silc_client_close_connection. Affected
1269 file lib/silcclient/client.c.
1271 * Added silc_client_del_client_entry to client library to free
1272 all memory of given client entry. Affected file is
1273 lib/silcclient/idlist.[ch].
1275 * Added new functions silc_client_del_channel and
1276 silc_client_del_server to delete channel and server entries.
1277 Affected file lib/silcclient/[silcapi.h/idlist.c].
1279 * Removed silc_client_del_client_by_id from silcapi.h.
1281 * Fixed the INFO command to return the server's own info
1282 correctly when querying by Server ID. Affected file is
1285 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Removed the non-blocking settings in WIN32 code in the
1288 silc_sock_[read/write] and added SleepEx instead. Affected
1289 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1290 of input data is now checked with FIONREAD and ioctlsocket.
1292 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Call silc_schedule_task_del_by_context in the
1295 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1296 Affected file lib/silccore/silcprotocol.c.
1298 * Call silc_protocol_cancel for active protocols in the
1299 silc_server_close_connection if the funtion
1300 silc_server_free_sock_user_data has not been called.
1301 Affected file silcd/server.c.
1303 * Generic tasks cannot be deleted using the del_by_fd
1304 task deleting function since generic tasks does not match
1305 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1307 * Added a notion to SILCOPER help file that the SILCOPER works
1308 only on router server, not on normal server.
1310 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Added for WIN32 support for the new scheduler as well.
1313 Affected file lib/silcutil/win32/silcwin32schedule.c.
1315 * Fixed the SHA1 implementation to work on various platforms.
1317 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1320 API. It is part of the scheduler now. Everything else is
1321 as previously but some functions has changed their names.
1322 Checkout the lib/silcutil/silcschedule.h for the interface.
1323 Updated all applications to use the new interface. Affected
1324 files are lib/silcutil/silcschedule.[ch].
1326 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Found a bug in the SKE implementation. The HASH value,
1329 specified by the protocol, was not computed correctly. The
1330 public key of the responder was not added to the computation
1331 even though it is mandatory. Affected file lib/silcske/silcske.c.
1332 This unfortunately causes incompatibilities with older
1333 clients and servers.
1335 * Added WIN32 specific network init and uninit functions:
1336 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1337 the Winsock2. Affected file lib/silcutil/silcnet.h and
1338 lib/silcutil/win32/silcwin32net.c.
1340 * Set the socket always to nonblocking mode on WIN32 after
1341 reading data or writing data. Affected file is
1342 lib/silcutil/win32/silcwin32sockconn.c.
1344 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Fixed various compilation problems under WIN32. Affected
1347 files lib/silcutil/win32/silcwin32thread.c and
1348 lib/silcutil/win32/silcwin32schedule.c.
1350 * Removed all _internal.h #includes from public header
1351 files. Internal headers must never be included from
1354 Removed also the lib/silcske/payload_internal.h file.
1356 * All include files that may be needed (public and some others
1357 included by the public headers) by application developers are
1358 now copied to the ./includes directory. It does not copy any
1359 internal headers. Affected file Makefile.defines.pre and all
1360 Makefile.am's under lib/ and subdirs.
1362 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Do not change the ~/.silc directory's permissions automatically.
1365 Affected file irssi/src/silc/core/clientutil.c.
1367 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1369 * Do not cancel the protocol in silc_server_close_connection
1370 it might cause recursion. Now cancelled in the function
1371 silc_server_free_sock_user_data. Affected file silcd/server.c.
1373 * Fixed the silc_server_remove_clients_by_server to regenerate
1374 the channel keys correctly finally. Added also new function
1375 silc_server_remove_clients_channels to actually do it.
1376 Affected file silcd/server.c.
1378 * Fixed the silc_server_new_channel to not crash by giving
1379 wrong router to the new channel. Affected file is
1380 silcd/packet_receive.c.
1382 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1385 which is given as argument to the silc_client_alloc now.
1386 It can be used to configure the client and set various parameters
1387 that affect the function of the client.
1389 * The USERS command in server did not check whether the channel
1390 is private or secret. Affected file silcd/command.c.
1392 * Added new argument to the USERS command in protocol specification.
1393 The USERS command now can take the channel name as argument
1394 as well. Added support for this in client and server and
1395 updated the protocol specs.
1397 * Completed the GETKEY command in client. It can be now used
1398 to fetch also servers public key not only some clients.
1399 Affected files lib/silcclient/command[_reply].c.
1401 * Added silc_client_get_server to return server entry by the
1402 server name. Affected files lib/silcclient/silcapi.h and
1405 * Redefined the IDENTIFY command in protocol specification to be
1406 more generic. It now can be used to query information about
1407 any entity in the SILC Network, including clients, servers and
1408 channels. The query may be based either the entity's name
1409 or the ID. Added support for this in both client and server.
1411 Affected files silcd/command.c and lib/silcclient/command.c
1412 and command_reply.c.
1414 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1415 the _from_client and _from_server functions. Affected file
1418 * Added silc_client_get_channel_by_id_resolve to the file
1419 lib/silcclient/silcapi.h to resolve channel information by
1420 its ID. Added also silc_client_get_channel_by_id that
1421 does not resolve it from the server.
1423 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Added SilcServerEntry context into the client library
1426 to represent one server. The INFO command now allocates
1427 these to save the resolved server info. For now on the
1428 client library will also keep information about servers,
1429 connected and resolved with INFO.
1431 The INFO command now allocates the SilcServerEntry context
1432 and saves the server info there. The COMMAND_REPLY in
1433 the INFO now returns the parameters to application in
1434 same order as defined in the protocol specification.
1436 The entries are cached in the client->server_cache.
1438 * The INFO command is now issued after received the Client ID
1439 from the server. Affected file lib/silcclient/client.c.
1441 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1442 to the application as the mode changer might be server.
1443 It is guaranteed that NULL is not returned anymore to the
1444 application. Affected file lib/silcclient/client_notify.c.
1446 The ID Type is now also passed to the application so that
1447 it can check whether the returned entry is SilcClientEntry
1450 Added new function silc_client_get_server_by_id to return
1451 the server entry by ID. Affected files are the
1452 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1454 * Do not create the channel in the Irssi SILC Client when issuing
1455 the JOIN command but when received the sucessful JOIN command
1456 reply. Otherwise the channel might get created even though we
1457 could not join it. The Affected file is
1458 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1460 * Fixed a channel joining bug in router. The router must also
1461 check the channel modes, invite and ban lists etc. when serving
1462 the JOIN command sent by normal server. Affected file is
1463 silcd/command.c. The router now resolves the client's
1464 information from the server who sent the JOIN command if it
1465 does not know it, and processes the JOIN command only after
1468 * Changed the SilcCommandCb to take new argument; void *context2.
1469 Affected file lib/silccore/silccommand.h
1471 The second argument in the command callbacks in the server now
1472 includes the SilcServerCommandReplyContext if the command was
1473 called as pending command callback from the command reply.
1474 Otherwise it is NULL. When called as pending the status of the
1475 command reply will be checked and if it was erronous the
1476 error will be sent to the original sender of the command.
1477 This way the client always receives the error messages even
1478 though the server was actually the one who received the error
1479 when it resent the command to router, for example. Affected
1480 files silcd/command[_reply].[ch].
1482 * Fixed sending WHOWAS command's error message to client if
1483 the requested client could not be found. It was missing.
1486 * Changed the CMODE and CUMODE commands reply arguments in the
1487 protocol specification. The Channel ID is now sent in both
1488 of the commands to identify the channel. Implemented this
1489 new feature to the client and server. Affected files
1490 lib/silcclient/command_reply.c and silcd/command.c.
1492 * Made better checks for invite and ban lists in the JOIN
1493 command in server. Affected file silcd/command.c.
1495 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * The server now performs the incoming host IP/DNS lookup
1498 using the silc_socket_host_lookup and thus does not block
1499 the server anymore. Affected file silcd/server.c.
1501 * Completed the multi-thread support for SILC Scheduler in
1502 the lib/silcutil/silcschedule.c.
1504 * Fixed the configure.in.pre to detect the pthread correctly
1507 * Fixed a deadlock in silc_task_queue_wakeup in the file
1508 lib/silcutil/silctask.c.
1510 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Added new function silc_schedule_wakeup that is used in
1513 multi-threaded environment to wakeup the main thread's
1514 schduler. It needs to be used when a thread adds a new task
1515 or removes a task from task queues. After waking up, the
1516 scheduler will detect the task queue changes. If threads
1517 support is not compiled in this function has no effect.
1518 Implemented the wakeup mechanism to both Unix and WIN32
1519 systems. Affected files are lib/silcutil/silcschedule.[ch],
1520 lib/silcutil/unix/silcunixschedule.c and the
1521 lib/silcutil/win32/silcwin32schedule.c.
1523 * Added new function silc_task_queue_wakeup to wakeup the
1524 scheduler by the specified task queue. Affected file
1525 lib/silcutil/silctask.[ch].
1527 * The silc_socket_host_lookup_start now wakes up the scheduler
1528 after adding the timeout task. Affected file is
1529 lib/silcutil/silcsockconn.c.
1531 * The silc_socket_host_lookup is synchronous now if the threads
1532 support is not compiled in. However, the callback is still
1533 called asyncronously through the scheduler, anyway. Affected
1534 file lib/silcutil/silcsockconn.c.
1536 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Added new function silc_socket_host_lookup to perform
1539 asynchronous IP and FQDN lookups for the socket connection.
1540 Affected files lib/silcutil/silcsockconn.[ch].
1542 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1545 that may or may not compile the mutex support in.
1547 Changed the silc_mutex_alloc interface. It allocates the
1548 mutex now to the sent pointer and returns TRUE or FALSE.
1550 Affected file lib/silcutil/silcmutex.h.
1552 * Wrote the SILC Task Queue interface to support multi-threads.
1553 Affected file lib/silcutil/silctask.[ch].
1555 * Wrote the SILC Scheduler to support multi-threads. Affected
1556 file lib/silcutil/silcschedule.c.
1558 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1561 in lib/silcutil/win32/.
1563 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Defined SILC Mutex API and SILC Thread API and implemented
1566 them for Unix. Affected files are
1567 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1568 lib/silcutil/unix/silcunixmutex.c and
1569 lib/silcutil/unix/silcunixthread.c.
1571 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Fixed the silc_server_remove_clients_by_server's channel
1574 key re-generation. The hash table handling was incorrect
1575 and would not work with many channels. Affected file is
1578 * Fixed some memory leaks around the server code.
1580 * Rewrote the silc_server_get_users_on_channel to support IPv6
1581 based Client ID's. Affected file silcd/server.c.
1583 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1584 specification. However, a separate document must be written
1585 to define the detailed signing procedure and the payload
1586 associated with the flag. Defined the flag to the
1587 lib/silccore/silcchannel.h as well.
1589 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Changed the dynamic tables to static size tables in the
1592 lib/silccrypt/silchmac.c.
1594 * Removed GCC dependencies from the code. A patch by cras.
1596 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Do not show the error "Error receiving packet bla bla"
1599 in server if it really was not an error (-2 means that reading
1600 is pending). Affected file silcd/server.c.
1602 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Fixed a possible crash in silc_server_remove_clients_by_server
1605 in silcd/server.c. Fixed there also some memory leaks.
1607 * Fixed the silc_idlist_replace_client_id. It could replace
1608 wrong key in the hash table. Affected file silcd/idlist.c.
1610 * Do not check whether there are global users on the channel
1611 if the channel->global_users is FALSE. Affected functions
1612 silc_server_remove_from_one_channel and
1613 silc_server_remove_from_channels in silcd/server.c. Also,
1614 do not check if the removed client is local as we can be
1615 sure that global client was not removed from the channel
1616 and checking for global users is not needed.
1618 * The silc_server_remove_clients_by_server now re-generates
1619 the channel keys correctly for those channels that had
1620 clients removed from them. Affected file silcd/server.c.
1622 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Found the reason of random crashes in the server. We weren't
1625 ignoring the SIGPIPE signal (which can be sent in write())
1626 and it crashed the server. Affected file silcd/silcd.c.
1628 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Assure that sock->user_data is not NULL in the function
1631 silc_server_packet_send in silcd/packet_send.c.
1633 * Disconnect the remote connection if it could not be added
1634 to any ID lists in the server. The affected file is
1637 * Check in silc_server_packet_send[_real/dest] that the
1638 socket is not disconnecting and ignore the data if it is.
1639 Affected file silcd/packet_send.c.
1641 * Define inline to __inline on native WIN32 compilation.
1642 Affected file includes/silcwin32.h.
1644 * Added some explicit type casts for inline code since MSVC
1645 require them. Affected files lib/silcutil/silcbuffer.h,
1646 lib/trq/silcdlist.h and lib/trq/silclist.h.
1648 * Print warning in log files from now on if the packet
1649 decryption fails. Affected file silcd/server.c.
1651 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Changed the `say' client operation's interface to accept
1654 new `type' argument to indicate the type of the message sent
1655 by the library. The application may filter the library's
1656 messages according the type. The affected file is the
1657 lib/silcclient/silcapi.h.
1659 * Added two new functions to lib/silcclient/silcapi.h:
1660 silc_client_del_client and silc_client_del_client_by_id.
1661 Affected file lib/silcclient/idlist.c.
1663 * Moved the clientincludes.h from includes/ to silc/ and
1664 serverincludes.h from includes/ to silcd/.
1666 * The modes for the CMODE and CUMODE are now passed as
1667 uint32 for application with COMMAND_REPLY. The affected
1668 file is lib/silcclient/command_reply.c.
1670 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1672 * /WHOIS without arguments shows client's own information.
1673 Affected file lib/silcclient/command.c.
1675 * Changed PING to not accept any arguments. The specs
1676 says that client can ping only the connected server so
1677 requiring an argument is not needed. Affected file is
1678 lib/silcclient/command.c.
1680 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Fixed a fatal bug in private message sending and reception
1683 encryption and decryption when using private message keys.
1684 The implementation was incorrect and did not follow the
1685 specification. It causd that some of the message were
1686 lost since it did not use the sending and receiving keys
1687 as the protocol suggests. This has been fixed and will cause
1688 incompatibilities with older clients when sending private
1689 message encrypted with private message keys. Affected files
1690 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1691 and various other in Irssi SILC Client.
1693 Added `responder' boolean argument to the functions
1694 silc_client_add_private_message_key[_ske] to indicate when
1695 the key is added as responder or initiator of the key
1698 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Removed the silc_ske_check_version function and created
1701 a SilcSKECheckVersion callback. Added also a function
1702 silc_ske_set_callbacks that is now used to set all SKE
1703 callbacks. The callback functions are not given to
1704 the SKE functions anymore, but this function is used to
1707 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1709 * Added `silc_version' argument to the silc_client_alloc
1710 to define the version of the application for the library.
1711 The library will use the version string to compare it
1712 against the remote host's (usually a server) version
1713 string. Affected file lib/silcclient/silcapi.h
1715 * Added the KE protocol context to Key Agreement context
1716 in client library so that we can abort the SKE if it
1717 is in process when we get timeout. Affected file is
1718 lib/silcclient/client_keyagr.c.
1720 * Do not resolve the client ID forever if it returns in the
1721 first time that such client does not exist. This was done
1722 for example with private message. Affected file is
1723 lib/silcclient/client_prvmsg.c.
1725 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1727 * Do not add regex.h for WIN32. The affected file
1728 includes/silcincludes.h.
1730 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1731 not work yet 100%. It generates the DLL's automatically
1732 when compiling with --with-win32 under cygwin.
1734 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * lib/contrib/regex.c is not compiled on WIN32.
1738 * Added silc_net_get_socket_opt function to the
1739 lib/silcutil/silcnet.h.
1741 * Added includes/silcwin32.h for WIN32 specific includes
1744 * Do not use ptime structure or any of the posix process
1745 functions on WIN32 in lib/silccrypt/silrng.c.
1747 * Added silc_gettimeofday to provide generic function
1748 for struct timeval on all platforms. Added the function
1749 to lib/silcutil/silcutil.h.
1751 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1754 library as they clearly belong there. As a plus side we
1755 can make the actual socket connection routines platform
1758 Added also new generic function silc_socket_read and
1759 silc_socket_write (that used to be silc_packet_[read/write].
1760 The implementation of these are platform specific.
1762 * Added WIN32 specific routines of silc_socket_[read/write]
1763 to lib/silcutil/win32/silcwin32sockconn.c.
1765 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Added preliminary support for native WIN32 compilation under
1768 cygwin (using the -mno-cygwin option for GCC) to the
1769 ./configure.in.pre. The --with-win32 now prepares the
1770 compilation for native WIN32.
1772 * Rewrote the SILC Scheduler interface in the file
1773 lib/silcutil/silcschedule.h. The scheduler is now context
1774 based and does not have anymore any global static scheduler.
1775 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1776 and created lib/silcutil/win32 directory for WIN32 based
1779 * Added Unix specific network routines to the
1780 lib/silcutil/unix/silcunixnet.c and the old
1781 lib/silcutil/silcnet.c includes now only generic routines.
1783 Added WIN32 specific network routines to the
1784 lib/silcutil/win32/silcwin32net.c.
1786 * Added Unix specific utility functions from the
1787 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1789 * Added WIN32 SILC Scheduler to the file
1790 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1793 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Do not handle JOIN notify in the server if the target client
1796 is not registered (idata->registered == FALSE). The affected
1797 file is silcd/packet_receive.c.
1799 * Update the nickrec->founder in event_cumode in the Irssi SILC
1800 client. Affected file irssi/src/silc/core/silc-channels.c.
1802 * Fixed the CUMODE_CHANGE notify handling in the server when
1803 server and router are announcing their clients on channels.
1804 Now the mode changes are saved and notified correctly. The
1805 affected file is /silcd/packet_receive.c.
1807 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1808 They really did not replace the cache entry in the ID Cache.
1809 Now they do that. Affected file silcd/idlist.c.
1811 * Fixed the KICK notify handling in the Irssi SILC client to
1812 update the channel records so that the kicked client does not
1813 appear to be on the channel. The affected file is
1814 irssi/src/silc/core/silc-channels.c.
1816 * Always update the conn->current_channel when executing command
1817 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1819 * Fixed the KILL notify handling in Irssi SILC client to remove
1820 the killed client on all channels.
1822 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Fixed the silc_parse_command_line to remove extra spaces
1825 from the start and end of the arguments. Affected file is
1826 lib/silcutil/silcutil.c.
1828 * Cancel and free any active protocol in the function
1829 silc_server_close_connection. Affected file silcd/server.c.
1831 * Cancel and free any active protocol in the function
1832 silc_client_close_connction. Affected file is
1833 lib/silcclient/client.c.
1835 * Do not execute the KILL command for clients that are in
1836 history (ie. they are not in the network). Affected file is
1839 * Fixed KILL notify handling, client does not crash anymore.
1840 Affected file irssi/src/silc/core/silc-channels.c.
1842 * Reduced the default packet buffer size from 2048 to 1024 in
1843 lib/silccore/silcpacket.c.
1845 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1846 counter to the SKE context that is incresed when the SKE library
1847 performs async operation outside the library. If the outside
1848 process frees the SKE context and FREED status will be set
1849 and the library will detect after the sync operation that the
1850 libary is freed. The affected files are
1851 lib/silcske/silcske[_status].[ch].
1853 * Resolve the client entry information in the function
1854 silc_client_channel_message to assure that NULL pointer is not
1855 passed as client entry to the application. */
1857 * Fixed the task timeout calculation to assure that there is
1858 never negative timeouts. The affected file is
1859 lib/silcutil/silcschedule.c.
1861 * Fixed the channel user mode notification sending in server.
1862 It was sent point-to-point to the router (or to server by router)
1863 but it needs to be destined to a channel. The routines now
1864 supports sending the channel user mode notifys to the channels
1865 when announcing clients and channels. Affected files are
1866 silcd/server.c and silcd/packet_receive.c.
1868 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1869 It did not actually replace the old channel entry in the cache.
1870 Affected file lib/silcclient/client_notify.c.
1872 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Fixed a possible crash in silc_packet_send_prepare. It now
1875 assures always that there is enough space in the buffer and
1876 at the tail area of the buffer (for MAC).
1878 Fixed the inbound buffer reallocation in silc_packet_read.
1879 It was old code and did not handle the reallocation correctly.
1882 The affected file is lib/silccore/silcpacket.c.
1884 * Fixed buffer overflow in silc_parse_nickname in the file
1885 lib/silcutil/silcutil.c.
1887 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * make install generates new server keys only if there is not
1892 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1894 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1895 Added check that if the NOREPLY is set then we will not send
1896 the away message. This avoids infinite loop of away messages
1897 if both clients are away. The affected file is
1898 lib/silcclient/client_prvmsg.c.
1900 * Fixed client crash if /NICK was given without arguments.
1901 Affected file lib/silcclient/command.c.
1903 * Server does not send the invite list in INVITE command back
1904 to the client if the list was not altered. Added this notion
1905 to the protocol spec as well. Affected file silcd/command.c.
1907 Fixed possible crash in INVITE command by checking the
1908 value of silc_server_get_client_route command.
1910 * Fixed the INVITE notify type handling. The arguments are now
1911 taken in correct order and client does not crash. The affected
1912 file is irssi/src/silc/core/silc-channels.c.
1914 Removed the "Inviting xxx to channel" message from the
1915 client library away and let the application handle it.
1916 Affected file lib/silcclient/command.c. Added that message
1917 to Irssi SILC client's message formats.
1919 * Fixed CMODE command crash in client. It now checks the
1920 amount of arguments correctly and does not crash. The affected
1921 file is lib/silcclient/command.c.
1923 * Do not create new channel automatically in silc_channels_join
1924 but check whether the channel by that name already exists.
1925 Affected file irssi/silc/core/silc-channels.c.
1927 * Do not send the SERVER_SIGNOFF to router if the disconnected
1928 entity was the router. Affected file silcd/server.c.
1930 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1931 SILC client as it was missing from there.
1933 Added the handling of the KICK notify to the Irssi SILC client
1934 as it was missing. Added "you have been kicked" message to
1935 Irssi SILC client's message modules formats.
1937 Added the handing of the KILL notify to the Irssi SILC client
1938 as it was missing. Added the kill message module formats
1941 The affected file is irssi/src/silc/core/silc-channels.c.
1943 * The router did not save the channel mode the server announced.
1944 Affected file silcd/packet_receive.c.
1946 * Fixed a possible crash in INFO command in server. If the
1947 server did not provide the server info it crashed. Affected
1948 file silcd/command.c.
1950 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Fixed the GETKEY command in the server to check also the
1953 global list. Otherwise the GETKEY would not work correctly
1954 in normal SILC server. Affected file silcd/command.c.
1956 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Fixed GETKEY crash, it crashed if the command did not succseed.
1960 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1963 is now real and not just an macro interface to GMP.
1965 Removed the entire GMP from the source tree and imported new
1966 NSS MPI library instead. Reason for removing GMP is that it is
1967 extremely large and compiles extremely slow. The NSS MPI
1968 is only a few files and compiles in less than 10 seconds.
1969 The speed is also about the same as GMP. The MPI is imported
1970 to lib/silcmath/mpi.
1972 If the system has GMP installed we will still use the GMP.
1973 If it is not then the NSS MPI will be compiled.
1975 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Merged a long nickname (127 characters long) crash bugfix from
1978 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1980 * Merged a freed memory reference bugfix from Irssi CVS tree.
1981 Affected file irssi/src/core/commands.c.
1983 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Added the server's public key sving and verification to the
1986 server when performing the SKE. This was missing and the
1987 remote server's (or router's) public key was accepted without
1988 checking whether we have it previously or trust it at all.
1989 Affected file silcd/protocol.c.
1991 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Check in the silc_server_timeout_remote if protocol is active
1994 and make sure that the protocol's final callback is called so
1995 that all memory if freed. Affected file silcd/server.c.
1997 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * silc_server_whois_send_reply crashed the server if the nickname
2000 was 127 characters long. Affected file silcd/command.c.
2002 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2004 * Added sanity check to the silc_server_new_client. If the hostname
2005 is provided inside username then check that the provided hostname
2006 really is the same as the resolved one. If the hostname was not
2007 resolved then check it from the public key. Affected file is
2008 silcd/packet_receive.c.
2010 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2011 if the server disconnected us and the connection is not valid
2012 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2014 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2015 the library to the lib/silcutil/silcutil.[ch].
2017 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Close log file after open. Affected file
2020 lib/silcutil/silclog.c.
2022 * Check whether sock == NULL in silc_client_send_packet and return
2023 if it is. Affected file lib/silcclient/silcclient.c.
2025 * Check rec->entry == NULL in the Irssi SILC Client before
2026 sending the channel message. Affecte file is
2027 irssi/src/silc/core/silc-servers.c.
2029 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Merged a splitted window bugfix from Irssi CVS tree. The
2032 affected file is irssi/src/fe-text/textbuffer-view.c.
2034 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2035 It did not print nickname.
2037 * Improved the distributions system a bit.
2039 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2042 irssi/src/fe-text/gui-window.c.
2044 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2045 to in-active server. The affected file is
2046 irssi/src/silc/core/client_ops.c.
2048 * Resolve the client in USERS command reply if the entry does
2049 not have username resolved. The affected file is
2050 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2051 command to WHOIS command to really resolve stuff. The USERS
2052 is not used any more in any critical section so WHOIS can
2053 be used even though it might be slower than IDENTIFY.
2055 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2058 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Changed the protocol API a bit more consistent in the
2061 lib/silccore/silcprotocol.[ch].
2063 * Changed the following headers to ROBODoc format:
2065 lib/silccore/silcpayload.h
2066 lib/silccore/silcprotocol.h
2067 lib/silccore/silcsockconn.h
2069 All core library headers are now formatted.
2071 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Fixed a bug in Irssi SILC client; do not show that you are
2074 server/router operator if you really are not. Affected file is
2075 irssi/src/silc/core/client_ops.c.
2077 * Renamed silc_command_free_payload to silc_command_payload_free.
2078 Affected file lib/silccore/silccommand.h
2080 * Added silcmath.h to include the prototoypes of various routines
2081 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2084 * Changed the following headers to ROBODoc format:
2086 lib/silccore/silcchannel.h
2087 lib/silccore/silccommand.h
2088 lib/silccore/silcid.h
2089 lib/silccore/silcidcache.h
2090 lib/silccore/silcmode.h
2091 lib/silccore/silcnotify.h
2092 lib/silccore/silcpacket.h
2093 lib/silcmath/silcmath.h
2095 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Added checking to the server code not to start the server if
2098 ciphers and stuff are not configured properly. Affected files
2099 silcd/serverconfig.[h] and silcd/server.c.
2101 * Changed the layout of the header files of the public interfaces
2102 in the SILC libraries. The new layout supports ROBODoc
2103 documentation tool (and some others) so that it is easy to create
2104 a library reference manual. All the other headers and source
2105 code must still follow the CodingStyle document. Also source
2106 code must not include these ROBODoc stuffs, only the headers.
2107 Furthermore, all public interface headers must now be named
2108 by using `silc' prefix, example: silcapi.h, silccipher.h.
2109 Some files were renamed due to this. All the other headers
2110 must not be used as public interfaces. I will update the
2111 CodingStyle document later. Changed following headers, so far:
2113 lib/silcclient/silcapi.h
2114 lib/silccore/silcauth.h
2115 lib/silccore/silcprivate.h
2116 lib/silccrypt/silcdh.h
2118 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Removed silc_client_packet_send_flush from the client library
2123 as it is not needed. Affected file lib/silcclient/client.[ch].
2125 * Added printing of message of unresolved authentication method
2126 to the Irssi SILC client. Added it to the module formats.
2127 Removed the same message from the client library.
2129 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Added new distribution feature, DISTLABEL. Every distribution
2132 can define own preprocessor label that can be used in the
2133 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2134 file distributions, acconfig.h.pre and prepare.
2136 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Added Makefile.defines_int to include the actual definitions
2139 for Makefile.defines.in. Tested the new distribution system,
2140 created distributions and tested installation.
2142 * Added AWAY message printing to the Irssi SILC client. Added
2143 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2145 * Added SCONNECT command to call the SILC's CONNECT command.
2146 Cannot use CONNECT directly since Irssi uses that internally.
2147 Affected file irssi/src/silc/core/silc-servers.c.
2149 Added ACTION local command. It is same as ME command but takes
2150 the channel as mandatory argument.
2152 Rewrote some of the Irssi's help files to suite for SILC
2155 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Added Makefile.defines[.in] that should for now on be included
2158 in all Makefile.am file in the source tree. That file includes
2159 all common compilation definitions for SILC source tree.
2161 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Minor changes to the ./prepare script to change the package
2164 name according the distribution name to the configure.in.
2166 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Created new distribution system. Added file `distributions'
2169 that defines all the distributions that can be created out of
2170 the SILC source tree. The ./prepare script now reads that
2171 file to determine how to prepare the distributions. The
2172 first argument to the ./prepare is the name of the distribution
2173 and second is the version of the distribution. If given
2174 without arguments it creates the default (toolkit) distribution
2175 with the default version (defined in ./prepare).
2177 All Makefile.am files that are subject to the distributions
2178 are now named as Makefile.am.pre. These are ./Makefile.am
2179 and lib/Makefile.am. Others may be changed later.
2181 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Added invite list, ban list, some key management and connection
2184 error message printing to module formats in the Irssi SILC client.
2186 * Added new silc_client_set_away_message to set the away message
2187 that is back to the person who sent private message. The
2188 affected file lib/silcclient/silcapi.h and the
2189 lib/silcclient/client_prvmsg.c.
2191 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Fixed the private message sending in the Irssi SILC client,
2194 added local command KEY to the Irssi SILC client.
2196 Added key management and key agreement message formats to the
2197 irssi/src/fe-common/silc/module-formats.[ch].
2199 Added USERS (alias WHO) printing, server/router operator
2200 indication and LIST command printing to the module formats.
2202 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Fixed channel joining notify handling, cumode notify handling
2205 from Irssi SILC client.
2207 * Added SILC specific module-formats to the Irssi SILC client so
2208 that SILC specific message hilighting, colors etc is possible.
2209 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2211 Added channel mode, channel user mode, actions, notices,
2212 whois and whowas printing to the the module-formats.c.
2214 * Fixed a bug in channel deletion in the server. The channel
2215 is not left to the cache even if the channel founder auth mode
2216 is set when there are no users anymore on the channel. Affected
2217 file silcd/server.c.
2219 * The silc_net_localhost now resolves the entire hostname including
2220 the domain name. Affected file lib/silcutil/silcnet.c.
2222 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Changed the ask_passphrase client operation to be ascynchronous.
2225 It has now a completion callback and a context that the
2226 application must call after it has got the passphrase from
2227 the user. Affected files lib/silcclient/silcapi.h,
2228 lib/silcclient/protocol.c, lib/silcclient/command.c and
2231 Added SilcAskPassphrase callback that the application calls
2232 to deliver the passphrase to the library.
2234 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2235 The public key verification and especially a certificate
2236 verification is asynchronous procedure.
2238 Added new SILC_SKE_STATUS_PENDING status to indicate the
2239 request is pending and a callback will be called to finalize
2242 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2243 indicate that remote end did not send its public key (or
2244 certificate), even though we require it. Added check for this
2245 condition in the SKE. This was a security bug, now fixed.
2247 Defined new SilcSKEVerifyCbCompletion callback that is called
2248 when the verification process is completed.
2250 The affected files lib/silcske/silcske_status.h and
2251 lib/silcske/silcske.[ch].
2253 * Changed the verify_public_key client operation to be async
2254 as well. Defined SilcVerifyPublicKey callback that is used to
2255 indicate the success of the public key verification process.
2257 Changed the server and client to use the new async client
2260 * Changed the Irssi SILC client's internal scheduler to be called
2261 twice as many times as it used to be. As a result the client
2262 should be a bit faster now. Affected file is
2263 irssi/src/silc/core/silc-core.c.
2265 * Added support to Irssi SILC client of asynchronous public key
2266 verification and passphrase inquiry. Affected file is
2267 irssi/src/silc/core/silc-core.c.
2269 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Do not say "You have left channel %s" in client library.
2272 Moved it to the application. Affected files are
2273 lib/silcclient/command.c and silc/client_ops.c.
2275 * Fixed silc_client_get_clients. Command context was not
2276 duplicated and was freed memory in the callback. Affected
2277 file lib/silcclient/idlist.c.
2279 * Do not say "you are now talking..." on JOIN command in the
2280 client library. The appliation must handle it.
2282 * Do not say ".. changed topic to" in command reply in the
2283 client libary. The application must handle it.
2285 * Fixed TOPIC command sending in the client library.
2287 * Fixed a memory leak in silc_client_command_free in the file
2288 lib/silcclient/command.c.
2290 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Imported a modified version of Irssi client to the source tree.
2293 The Irssi will be used to create a new client called
2294 Irssi SILC. Imported to irssi/.
2296 Added silc_core_init_finish function to the Irssi. Affected
2297 file irssi/configure.in.
2299 A lot changes in the Makefile.ams around the irssi tree.
2301 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Do not rehash if the new size is same as the old size of the
2304 hash table, in the silc_hash_table_rehash*. The affected file
2305 lib/silcutil/silchashtable.c.
2307 * Replaced hash_table_del_by_context calls from the server
2308 (when channel->user_list and client->channels) to the
2309 hash_table_del as it is sufficient and faster.
2311 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Added silc_hash_table_list, silc_hash_table_get and the
2314 SilcHashTableList structure to provide an alternative way to
2315 traverse the hash table. The affected files are
2316 lib/silcutil/silchashtable.[ch].
2318 * Changed the server's idlist routines to use the hash table
2319 routines to optimize the code.
2321 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Replaced the client entry's `channel' list and channel entry's
2324 `user_list' list to hash tables for optimized lookup. Changed
2325 the code to use the hash table interface around the code.
2326 Affected file lib/silcd/idlist.[ch].
2328 * Added `auto_rehash' boolean argument to the function
2329 silc_hash_table_alloc to indicate whether the hash table should
2330 auto-rehash when it thinks is appropriate time. It will
2331 increase the hash table size if the there is twice as much
2332 entries in the table than the size of the table, and will
2333 decrease the size if there are twice as less entries than
2334 the size of the table.
2336 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2340 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * silc_idcache_purge_by_context deletes the entry now by context
2343 as it is supposed to do. Affected file lib/silccore/idcache.c.
2345 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2346 client is not anymore valid (WHOWAS givens the info) and not
2347 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2349 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Removed the `data' and `data_len' arguments from the ID Cache
2352 interfaces and added `name' argument. ID Cache does not handle
2353 anymore the binary data only a names associated with given ID.
2355 * When hashing a Client ID with silc_hash_id the entire ID is
2356 not hashed anymore, instead only the hash of the Client ID is
2357 hashed. This way we can access the Client ID from the cache
2358 with Client ID but with the hash of the ID (which is a hash of
2359 the nickname) as well without any difference in performance.
2361 Added also silc_idcache_find_by_id_one_ext to do one on one
2362 searching when we have the actual ID. Added also function
2363 silc_hash_client_id_compare. The affected files are
2364 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2366 * When hashing the name associated with a ID it is always done
2367 in lowercase. This way we can access the cache without worrying
2368 about case-sensitivity, even though, for example nicknames are
2371 * Fixed a bug in server with channel message sending. It put
2372 wrong ID type as destination ID. The affected file
2373 silcd/packet_send.c.
2375 * silc_idcache_del_by_context now deletes from all hash tables
2376 by context. Affected file lib/silccore/idcache.c.
2378 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2380 * Changed the client library to use the new ID Cache interface.
2381 Changes around the source tree.
2383 * Added silc_hash_table_rehash_ext to rehash with specific
2384 hash function. Affected file lib/silcutil/silchashtable.[ch].
2386 * Added silc_hash_string_compare to compare two strings in the
2387 hash table. Affected file lib/silcutil/silcutil.[ch].
2389 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Added new function silc_idcache_del_by_context into the
2392 lib/silccore/idcache.[ch].
2394 * Changed the server's ID list routines to use the new ID Cache
2395 interface. Changes around the source tree.
2397 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Added silc_hash_table_del[_by_context]_ext functions in to the
2400 lib/silcutil/silchashtable.[ch].
2402 Removed silc_hash_table_find_all* routines and added new
2403 silc_hash_table_find_foreach to replace them.
2405 Added silc_hash_table_replace_ext function as extended
2406 replacing function. Separated the simple hash table interface
2407 from the extended hash table interface in the file
2408 lib/silcutil/silchashtable.h.
2410 * Fixed minor bugs and changed it to use some of the new
2411 hash table functions in lib/silccore/idcache.c
2413 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Added new function silc_hash_table_find_all to return all keys
2416 in the hash table by the specified key. As the hash table is
2417 collision resistant it also makes it possible to have several
2418 duplicate keys in the hash table. This function may be used to
2419 find all of the keys from the hash.
2421 Added user_context arguments to the SilcHashFunction,
2422 SilcHashCompare and SilcHashDestructor to deliver user specified
2425 Added new fuctions silc_hash_table_find[_all]_ext to do
2426 extended lookup with specified hash and compare functions and
2427 specified user contexts.
2429 Added new function silc_hash_table_add_ext to add the key
2430 with specified hash function and user context.
2432 Added new function silc_hash_table_foreach to traverse all
2433 entrys in the hash table. Added SilcHashForeach callback
2436 Added new function silc_hash_table_del_by_context to delete
2437 the entry only if the context associated with the key matches.
2439 Affected files are lib/silcutil/silchashtable.[ch].
2441 * Removed silc_hash_[server/client/channel]_id and added just
2442 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2443 silc_hash_id_compare to compare two ID's using as the hash table
2444 comparison function. Added also silc_hash_data to hash
2445 binary data and silc_hash_data_compare to compare it.
2447 * Removed silc_idlist_find_client_by_hash as it is not needed
2448 anymore. Affected file silcd/idlist.[ch].
2450 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2451 to use internally the SilcHashTable. The new ID Cache is a lot
2452 faster than the old one. Some of the ID Cache interface was also
2453 rewritten and obsolete and stupid functions were removed.
2455 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Added entry_count field to the SilcHashTable to keep the number
2458 of the entries in the table. Implemented the function
2459 silc_hash_table_rehash. Added new function
2460 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2462 Fixed a minor bug in silc_hash_table_free.
2464 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2465 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2466 into the lib/silcutil/silcutil.[ch].
2468 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Implemented a collision resistant hash table into the
2471 lib/silcutil/silchashtable[ch]. See the header and the source
2472 for the SilcHashTable API.
2474 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Merged dotconf version 1.0.2 into lib/dotconf.
2478 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Do not compile anything in lib/silcsim/* if the SIM support
2481 is not enabled. The tree should now compile without problems
2484 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Compiled the SILC under cygwin. Compiled and tested briefly
2487 without problems. More tests needed. The SIMs didn't compile
2490 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2492 * Fixed possible crash in silc_get_username in the
2493 lib/silcutil/silcutil.c.
2495 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Fixed a va_arg in silc/client_ops.c.
2499 * Oops, RC5 routines were named AES and caused some problems
2500 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2502 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Added new SilcIDIP structure into the lib/silccore/id.h and
2505 replaced the old `ip' fields from all SILC ID's to that type.
2506 This is a step towards IPv6 support.
2508 The silc_id_get_len takes now the ID as an extra argument.
2509 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2510 both IPv4 and IPv6 based ID's.
2512 The affected files are lib/silccore/id.[ch] and other files
2513 around the tree using these routines.
2515 * Removed the ID length arguments in server from various
2516 silc_server_send_notify_* routines -> they are not needed
2519 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Fixed memory leak in silc_encode_pem_file in the file
2522 lib/silcutil/silcutil.c.
2524 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Check minor version as well in the SKE. Affected files are
2527 silcd/protocol.c and lib/silcclient/protocol.c.
2529 * Added --identifier option to the server so that an identifier
2530 can be when creating the public key for the server. Affected
2531 file is silcd/silcd.c.
2533 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2534 lib/silccrypt/silcpkcs.c.
2536 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Register default ciphers and stuff when using -C option with
2539 the server. Affected file sildc/silcd.c.
2541 * Put back the servers public key filename format, it is better
2542 than the new one. For now, the client keys are saved with the
2543 new filename format. The affected file silc/client_ops.c.
2545 * Implemented the Cipher API for the rest of the ciphers that
2546 did not implement it or implemented it the wrong way.
2548 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Register default ciphers and stuff when using the -S option
2551 in the client. Affected file silc/silc.c. Same also when
2552 creating new key pair with -C option.
2554 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Fixed the silc_verify_public_key client operation function to
2557 save the public keys differently. The fingerprint is now
2558 used as filename and not the hostname. This way also the
2559 client keys are saved uniquely and not with hostnames. The
2560 affected file is silc/client_ops.c.
2562 * Trimmed the silc_hash_fingerprint function to remove extra
2563 whitespaces from the end of the fingerprint. The affected
2564 file is lib/silccrypt/silchash.c.
2568 * Added silc_cipher_register_default function to register all
2569 default ciphers. It can be used when configuration files
2570 does not exist and the application does not want any specific
2571 ciphers in any specific order.
2573 The SilcDList is now used as silc_cipher_list dynamically
2574 allocated cipher list. Removed the static list all together
2575 and now all ciphers must be allocated to the dynamic list.
2576 The silc_cipher_alloc routine was changed to check only the
2579 All silc_cipher_* routines that used to return int returns
2582 The affected files lib/silccrypt/silccrypt.[ch].
2584 * The same thing was done to silc_hash_* as for silc_cipher_*
2585 routines. Affected files lib/silccrypt/silchash.[ch].
2587 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2588 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2589 Added also silc_pkcs_[un]register[_default] functions.
2590 Removed the data_context from the PKCS API.
2592 * Added silc_hmac_register_default function to register default
2593 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2594 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2595 to unregister all hmacs at once.
2597 * Register the default ciphers, hash functions, PKCSs and HMACs
2598 if client's configuration file does not exist. The affected
2601 * The client did not load the hash functions from the SIM
2602 modules at all. Added support for this. Affected file is
2603 silc/clientconfig.c.
2605 * When decoding public key with silc_pkcs_public_key_decode, check
2606 the supported algorithm only if PKCS are registered. Affected
2607 file lib/silccrypt/silcpkcs.c. The same was done with the
2608 silc_pkcs_private_key_decode.
2610 * Fixed the SILC List routines to keep the list always in order.
2611 It used to change the list's order when traversing the list but
2612 not it preserves the order. Affected file lib/trq/silclist.h.
2614 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Added the client library to use the SilcSocketConnection's
2617 reference counter (by silc_socket_dup) to prevent the bug that
2618 the socket object may be freed underneath async operation.
2620 * The name resolv library checking fixes in the configure.in.pre.
2623 * Created new version of the protocol drafts for future
2624 development. The -03 drafts are the ones that will be changed
2625 in the trunk now and the -02 will remain as they are.
2627 * Send list of CUMODE notifys to the router when announcing
2628 the channel users to the router. Affected file silcd/server.c.
2629 If the router receiving channel founder CUMODE for a channel
2630 that already has channel founder it will send CUMODE notify
2631 to the sender to remove the channel founder rights from the
2632 announced client. Affected file silcd/packet_receive.c.
2634 * The CUMODE notify may now use Server ID as well as the entity
2635 who changes the mode. Updated protocool specs.
2637 * Updated INSTALL and README files.
2639 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * New web pages in the http://silc.pspt.fi. The pages was
2646 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Implemented the [DenyConnectin] config section in the server.
2649 Added silc_server_config_denied_conn to check whether incoming
2650 connection is denied. Affected file silcd/serverconfig.[ch].
2652 * Do not check the ports when checking the incoming configuration
2653 data if the port is 0, meaning any. Affected file is
2654 silcd/serverconfig.c.
2656 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Fixed buffer overflow in silc_string_compare in the file
2659 lib/silcutil/silcutil.c.
2661 * Fixed double free in silc_server_command_leave in the file
2664 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Fixed the version checking in the server. Affected file is
2669 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Fixed the configuration data fetching when accepting new
2672 connections in the server. Affected file silcd/server.c.
2674 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Added `sender_entry' argument to the function
2677 silc_server_packet_relay_to_channel so that we can check
2678 whether some destination actually belongs to the same route
2679 the sender belongs (ie, we must not resend the packet to the
2680 sender). Affected file silcd/packet_send.[ch].
2682 * Added `servername' field to the SilcClientEntry in the server
2683 to hold the name of the server where client is from. Affected
2684 file is silcd/idlist.h.
2686 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Moved the channel message encrypting in the router betwen
2689 router connections from silc_server_channel_message to the
2690 silc_server_packet_relay_to_channel since we want to check
2691 whether we have anybody channel before encrypting anything.
2692 Affected files silcd/packet_[receive/send].c.
2694 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Fixed the [AdminConnection] server config section to support
2697 multiple entries. Affected file silcd/serverconfig.c.
2699 * Added support into the server to check the validity of the
2700 incoming connection before executing any KE or authentication
2703 * The connection configuration is now saved to the KE and
2704 connection auth protocol contexts and not fetched anymore in
2705 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2707 * The local hosts listenning address and port is also resolved
2708 now when starting the server. We want to have the socket object
2709 to include the real address and port for the listener. Added
2710 new function silc_net_check_local_by_sock into the files
2711 lib/silcutil/silcnet.[ch].
2713 * Fixed a broadcast bug in server -> do not broadcast if we
2716 * Fixed a routing bug. Do not route broadcast packets ever.
2717 Broadcast packets must be processed always and not routed since
2718 they may be destined to some other host than yourself and thus
2719 would get routed without no good reason. Affected file is
2722 * Added function silc_server_config_is_primary_route to check
2723 whether primary router connection has been configured (a router
2724 configuration that we are initiating). If there is not, we
2725 will assume that there is only two routers in the SILC network
2726 and we will use the incoming router connection as our primary
2727 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2729 * Changed the order of the broadcasting. Broadcast _after_ the
2730 packet has been processed not before. Affected file is
2733 * Fixed a [ClientConnection] parsing bug. The port was never
2734 parsed correctly thus resulting to port 0. Affected file
2735 silcd/serverconfig.c.
2737 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2738 argument and did not set the broadcast packet flag. Affected
2739 file silcd/packet_send.c. Fixed same bug in the function
2740 silc_server_send_notify as well.
2742 * If we receive NEW_ID packet for our own ID in the server, ignore
2745 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Removed the nickname from the Private Message Payload.
2750 Updated the code and the protocol specs.
2752 * Updated protocol specs for submitting to the IETF.
2754 * Tweaked the Random Number Generator a bit. Affected file
2755 lib/silccrypt/silcrng.c. Exported a new function
2756 silc_rng_[global]_add_noise which can be used to add more
2759 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Do not parse packets with different timeout when protocol
2762 is active -> may cause problem with rekey. Affected file
2765 * When server receives signoff notify it must not create
2766 new channel key if the client is on any channels since the
2767 sender of the signoff notify will create it.
2769 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Added printing of error messages during SKE protocol from the
2772 failure packet sent by server during SKE. Affected file
2775 * Removed the client's failure_callback handling with timeout
2776 and handle it immediately when received.
2778 * The SKE library returned wrong type in SUCCESS and FAILURE
2779 packets. They must be 32 bit MSB not 16 bit MSB.
2781 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Ok, rewrote the logic of the re-key and now it seems to work.
2784 I tested it on high traffic with frequent re-keys without
2785 problems. Added hmac_receive (and renamed hmac to hmac_send)
2786 in SilcClientConnection in lib/silcclient/client.h and
2787 in SilcIDListData in silcd/idlist.h. Also, removed the
2788 SilcPacketParserContext's cipher and hmac fields as they are
2789 not needed anymore and actually caused some problems when
2790 the ciphers and hmac's changed underneath the packet parser.
2792 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * If re-key protocol is active then process the incoming packets
2795 synchronously since we must assure that icoming packets encrypted
2796 with the old key is processed before the new keys is set to
2797 use. This is true other packets than for REKEY packets.
2798 Affected file silcd/server.c. The same was done to client library
2799 as well, affected file lib/silcclient/client.c.
2801 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Fixed bug in client and server to accept the force send if
2804 the packet is send from silc_[server/client]_packet_process
2805 function. Otherwise the packets are never delivered, oops.
2807 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Disable force sending of packets when REKEY protocol is active.
2810 We must assure that no packet is sent directly when rekey is
2811 performed. All packets must be sent through packet queue.
2812 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2813 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2814 function is silc_[server/client]_packet_send_real to check
2817 * Replaced the SIM paths from example config files to
2818 /usr/local/modules. Also, make install creates now
2819 /usr/local/silc/logs directory to hold all the SILC server
2822 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Made the configure.in.pre work on Solaris. Patch by salo.
2826 * Made all ciphers compatible with non-x86 machines. Defined
2827 CBC mode macros into lib/silccrypt/ciphers_def.h.
2829 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Fixed the make install.
2833 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * When MAC computation fails the silc_packet_decrypt returned 0
2836 even though it was supposed to return -1. Fixed this. The
2837 affected file is lib/silccore/silcpacket.c.
2839 * Do not replace the config files in /etc/silc (in make install)
2840 if they already exist. Affected file ./Makefile.am.
2842 * Do not send re-key packets immediately but through packet queue.
2843 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2845 * Changed silc_net_check_host_by_sock to return FALSE if the
2846 IP/DNS could not be resolved. Though, it returns the IP address
2847 now even if it could not resolve it (but returns also FALSE).
2848 Affected file lib/silcutil/silcnet.[ch].
2850 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added silc_pkcs_decode_identifier to decode the public key's
2853 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2854 Added also silc_pkcs_free_identifier. Added also new context
2855 SilcPublicKeyIdentifier.
2857 * Added -S option to the silc client. It is used to dump the
2858 contents of the specified public key file.
2860 * Changed the PKCS api to return the public key length when
2861 setting the public key.
2863 * Fixed a fatal bug in the public and private key file loading.
2864 Affected file lib/silccrypt/silcpkcs.c.
2866 * Execute the packet parsing for client with zero (0) timeout
2867 if the protocol is active. Affected file silcd/server.c.
2869 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Made the key generation options to the silcd program. Added
2872 -C option, equivalent to client's option.
2874 * Added new [ServerKeys] config section to the server. It
2875 configures the server's public and private key.
2877 * Defined generic Public Key Payload into the protocol
2878 specification to send specific type of public keys and
2881 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2882 public key or certificate.
2884 * Implemented the GETKEY command to the server and to the
2885 client library and on user interface.
2887 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Made preliminary `make install' work.
2891 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Added SilcServerRekey context into silcd/idlist.h.
2895 * Added the PFS support as defined in the specification to the
2896 SKE protocol. Affected files lib/silcske/*.c.
2898 * Added `ske_group' field to the SilcServerRekey context to hold
2899 the number of the SKE group that is used with PFS in re-key.
2900 Affected file silcd/idlist.h.
2902 * Added PFS re-key support to the server. Affected file is
2905 * Added silc_protocol_cancel to cancel execution of the next
2906 state of the protocol. Affected file is
2907 lib/silccore/silcprotocol.[ch].
2909 * Added the re-key support with and without PFS to the client
2910 library. Re-key is performed once in an hour, by default.
2912 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2913 Added silc_client_rekey_callback and silc_client_rekey_final.
2914 Affected files are lib/silcclient/protocol.[ch] and
2915 lib/silcclient/client.[ch].
2917 * Removed the `hmac_key' and `hmac_key_len' fields from the
2918 SilcClientConnection structure; not needed. Affected file is
2919 lib/silcclient/client.h.
2923 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Do not ask whether user wants to use the negotiated private key
2926 for private messages, just use it. Affected file is
2927 silc/local_command.c.
2929 * Added `send_enc_key' and `enc_key_len' fields to the
2930 SilcIDListData structure since they are needed in the re-key
2931 phase. Affected file is silcd/idlist.[ch].
2933 * Implemented the simple re-key protocol into the server.
2934 Affected files silcd/server.c and silcd/protocol.[ch]. The
2935 re-key will be performed once in an hour, by default.
2937 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2938 Added silc_server_rekey, silc_server_rekey_callback and
2939 silc_server_rekey_final.
2941 * Removed Tunneled flag from the protocol. Updated the code
2942 and the specifications.
2944 * Adde `pfs' field to the SilcIDListData to indicate whether
2945 the PFS is to be performed in the re-key. Affected file is
2948 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2951 int64 of at least the xintXX size. If void * is less that 4
2952 bytes uint32 * will be used. Defined bool as boolean.
2954 * Changed _ALL_ unsigned long and unsigned int to uint32,
2955 unsgined short to uint16 in the source tree.
2957 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2958 not handle clients that has entry->data.registered == FALSE.
2959 They are not in the network anymore. Affected file is
2962 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Implemented the sending of the SERVER_SIGNOFF notify in the
2965 server. Affected file is silcd/server.c.
2967 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2968 Added also silc_notify_payload_encode_args into the
2969 lib/silccore/silcnotify.[ch].
2971 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2972 Affected file silcd/packet_receive.c.
2974 * Implemented the SERVER_SIGNOFF notify handling in the client
2975 library. Affected file lib/silcclient/client_notify.c. Also,
2976 implemnted the printing of the SERVER_SIGNOFF info to the
2977 application. Affected file silc/client_ops.c.
2979 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2980 if the deleting was successful. Affected file silcd/idlist.[ch].
2982 * Added support for public key authentication in the connection
2983 authentication protocol in the client library. Affected file
2984 lib/silcclient/protocol.c.
2986 * Changed the server's silc_idlist_get_clients_by_* interface
2987 to support already allocated array so that new entries may be
2988 added to pre-allocated array. Affected file silcd/idlist.[ch].
2989 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2990 and command replies.
2992 * All command reply functions in the server now calls the
2993 pending command callback even if error occured. This way the
2994 error will be delivered to the client as well. Affected files
2995 silcd/command.c and silcd/command_reply.c.
2997 * Fixed INFO command to return local server's info if no server
2998 was provided. Affected file lib/silcclient/command.c.
3000 * Removed RESTART command for good. Updated the code and the
3003 * Rewrote parts of the task system. It is a bit simpler now.
3004 Removed unsued task priorities. The affected files are
3005 lib/silcutil/silctask.[ch].
3007 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3009 * Moved the USERS printing from the library to the application.
3010 Affected files lib/silcclient/command.c and silc/client_ops.c.
3012 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Added channel key re-key support. The re-key is perfomed
3017 only by the router and is done once in an hour. Added `rekey'
3018 field to the SilcChannelEntry in the server. Affected files
3019 silcd/server.c and silcd/idlist.h.
3021 * Added silc_task_unregister_by_context into the file
3022 lib/silcutil/silctask.[ch].
3024 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Added SILC_UMODE_GONE mode to indicate when the client is not
3027 present in the SILC network. Added also support to the local
3028 command AWAY that will set this mode. Added support of showing
3029 "xxx is gone" in WHOIS command. The USERS command shows the
3030 gone status as well.
3032 * Fixed setting server and router operator privileges in the
3033 server's UMODE command. Affected file silcd/command.c.
3035 * Merged the SKE KE1 and KE2 payloads into one payload. The
3036 new KE payload is equivalent to the old KE2 payload.
3038 Cleaned up the SKE Start Payload parsing. It now uses the
3039 simple buffer unformatting to do the parsing. A lot faster
3042 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3043 to the SKE that is used to indicate whether both of the SKE
3044 parties should perform authentication. By default only the
3045 responder performs authentication. By setting this flag also
3046 the initiator must do authentication. By default it is unset
3047 since in normal SKE case, client to server connection, only
3048 the responder should do authentication. When doing SKE between
3049 two clients both should perform authentication. Updated the
3050 code and the protocol specs.
3052 * A little fix to IDENTIFY command in the server. Search the
3053 client first by hash not nickname. Affected file is
3056 * Fixed the silc_client_close_connection to support closing
3057 the client to client connections wihtout deleting too much
3058 data. Affected file lib/silcclient/client.c.
3060 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3061 are received if protocol used to be active but is not anymore
3062 the application would crash due to NULL pointer dereference.
3063 Affected files silcd/server.c and lib/silcclient/client.c.
3065 * Added `hash' field to the SilcClientConnection to include
3066 the hash function negotiated in the SKE protocol.
3068 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3069 to set the channel founder authentication data. A client can
3070 claim the founder rights later by providing the authentication
3071 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3072 This way the channel founder can regain the channel founder
3073 privileges even it is left the channel. This works only on
3074 local server and the client must be connected to the same
3075 server to be able to regain the founder rights. Updated the
3076 protocol specs accordingly.
3078 Added support to the CMODE command in the client to set the
3079 founder auth data. Read the README to see how to set it.
3081 Added support to the CUMODE command to claim the founder
3082 rights. Read the README to see how to do it.
3084 Added support for the founder authentication to the Channel
3085 Entry in the server. Affected file silcd/idlist.h.
3087 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3088 server's CMODE command. Affected file silcd/command.c.
3090 * Added the following new functions into lib/silccore/silcauth.[ch]:
3091 silc_auth_get_method and silc_auth_get_data.
3093 * The server now saves the remote hosts public key to the
3094 SilcIDListData pointer. Affected file silcd/protocol.c.
3096 * The normal server now does not remove the channel entry from
3097 the cache if the founder authentication data is set. It used
3098 to remove it if the founder was the last one on the channel on
3099 the server and left the channel. The auth data is saved and
3100 if the channel is re-joined later the old entry is used with
3101 the old auth data. Affected files silcd/command_reply.c and
3104 * Removed the `pkcs' field from the SilcIDListData structure
3105 in the server; it is not used. Affected file silcd/idlist.h.
3107 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Fixed packet processing on slow links. Partial packets were
3110 never re-processed because the incoming data buffer was cleared
3111 by the application. Application must not directly clear the
3112 sock->inbuf, the packet processing routines handle it. Fixed
3113 this in client library and in server.
3115 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Fixed the WHOIS and IDENTIFY send reply function to really
3118 check whether to send list or just one entry. Affected file
3121 * Cleaned up the LEAVE command's channel key distribution. The
3122 affected file silcd/command.c.
3124 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3125 can enforce the channel mode as well. In that case the ID
3126 includes the ID of the server. The code now enforces the
3127 mode change if the router have different mode than the server.
3129 * The notify client operation with CMODE_CHANGE notify can now
3130 return NULL client_entry pointer if the CMODE was not changed
3131 by client. Application must check for this.
3133 * Added <Server ID> argument to INFO command to support server
3134 info fetching by Server ID.
3136 * Added silc_server_announce_get_channel_users to get assembled
3137 packets of channel users of the specified channel. Affected
3138 file silcd/server.[ch].
3140 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3141 was freed underneath the ID Cache.
3143 * Re-announce clients when the server received CHANNEL_CHANGE
3144 notify from the router. Affected file silcd/packet_send.c.
3146 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3149 crashed since it did not handle the fact that there is no cipher
3150 called "3" and didn't check the error condition. Now fixed.
3152 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3153 flag. It can be used to send message requests.
3155 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Implemented the RESTART command in the client.
3159 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3160 notice type messages. Added notice printing to the user
3163 * The channel keys are not re-generated if the channel's mode
3164 is PRIVKEY, ie private key on the channel exists. Affected
3165 files silcd/server.c and silcd/command.c.
3167 * Fixed a little bug in channel message delivery when channel
3168 private keys are set in the server. Affected file is
3169 silcd/packet_send.c.
3171 * Changed the setting on channel->on_channel = TRUE from the
3172 silc_client_save_channel_key to the JOIN command reply. The
3173 key payload is not received if the private channel key is set.
3174 Affected file lib/silcclient/command_reply.c and the
3175 lib/silcclient/client_channel.c.
3177 * When the CMODE_CHANGE notify is sent and the channel private
3178 key mode is removed the channel key must be re-generated in
3179 other cells as well. Added this support for the router in the
3180 silcd/packet_receive.c.
3182 * Added new local command NOTICE to send notice message on
3183 channel. Affected file silc/local_command.[ch].
3185 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Added new local command ME to the client. It is used to send
3188 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3189 some action. Affected file silc/local_command.[ch].
3191 * Changed channel_message and private_message client operations
3192 to deliver the message flags to the application. Added also
3193 the `flags' arguments to the silc_client_send_channel_message
3194 and silc_client_send_private_message functions. Affected file
3197 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Redefined the Private Message Payload to support private message
3200 keys and to support the new private message flags. Updated
3201 the protocol specs. Flags makes it possible to have for example
3202 CTCP style messages.
3204 * Added new type SilcPrivateMessagePayload and defined an API
3205 for it in the lib/silcclient/silcprivate.[ch].
3207 * Tested private message private keys successfully. Tested the
3208 private message key set, unset and list commands with the new
3211 * Redefined the Channel Message Payload to include the channel
3212 message flags (equal with private message flags) to support
3213 for example CTCP style messages.
3215 * Defined some of the message (for channel and private message)
3216 flags. Updated the protocol specs and added the flags to the
3217 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3219 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Added SilcKeyAgreementStatus type to the key agreement routines
3222 to indicate the current status and error if one occured.
3223 The status types are defined in the lib/silcclient/silcapi.h.
3225 * Added new local command KEY that is used to set and unset private
3226 keys for channels, set and unset private keys for private messages
3227 with remote clients and to send key agreement requests and
3228 negotiate the key agreement protocol with remote client. The
3229 key agreement is supported only to negotiate private message keys,
3230 it currently cannot be used to negotiate private keys for channels,
3231 as it is not convenient for that purpose.
3233 * Fixed a minor pending callback setting bug in the function
3234 silc_client_get_client_by_id_resolve, now the function works.
3235 Affected file lib/silcclient/idlist.c.
3237 * Added function silc_net_get_local_port to get local bound
3238 port by socket. Added to lib/silcutil/silcnet.[ch].
3240 * Added `sockets' and `sockets_count' fields to the SilcClient
3241 object. They hold the sockets of the listenning sockets in
3242 the client. Listenning sockets may be for example the key
3243 agreement server. Affected file lib/silcclient/client.[ch].
3244 Added functions the silc_client_add_socket and the
3245 silc_client_del_socket. They are exported to the application
3248 * Added ~./silc/clientkeys to support other client's public keys.
3250 * Renamed verify_server_key client operation to verify_public_key
3251 and added one argument to indicate the type of the connection
3252 (server, client etc.).
3254 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Added silc_server_connection_auth_request to handle the
3257 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3258 silcd/packet_receive.[ch].
3260 * Added silc_server_send_connection_auth_request into the
3261 silcd/packet_send.c to send the connection auth request packet.
3263 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3266 * Fixed the public key authentication in responder side in the
3267 server. The `auth_data' pointer includes the SilcPublicKey
3268 not the path to the public key. Affected file silcd/protocol.c.
3270 * Implemented the public key authentication in the initiator side
3271 in the server. Affected file silcd/protocol.c.
3273 * Removed the [RedirectClient] config section from the server
3274 configuration. Is not needed and I don't want to implement it.
3276 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Cleaned up the CMODE command in the server. It now works
3279 correctly and supports all the modes defined in the protocol.
3280 Affected file is silcd/command.c.
3282 * Added `hmac_name' field to the SilcChannelEntry in the server
3283 to hold the default HMAC of the channel. It can be set when
3284 creating the channel (with JOIN command). Affected files
3287 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3288 type to indicate the change of the current cipher and hmac
3289 on the channel. Client can safely ignore the <cipher> argument
3290 (if it chooses to do so) since the CHANNEL_KEY packet will
3291 force the channel key change anyway. The <hmac> argument is
3292 important since the client is responsible of setting the new
3293 HMAC and the hmac key into use.
3295 * Fixed the CMODE command in the client library as well.
3297 * Tested CMODE command in router environment successfully.
3299 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Show the version of the remote client (or server) when connecting
3302 to the server. It is logged to the log file. Affected file
3303 is silcd/protocol.c.
3305 * Fixed the KILLED notify handling in the client library. The
3306 client must be removed from all channels when receiving the
3309 Also, do not remove the client entry when giving the KILL
3310 command but when the KILLED notify is received.
3312 * Removed silc_idlist_find_client_by_nickname from the server.
3313 Not needed anymore. Affected files silcd/idlist.[ch].
3315 * Implemented the CHANNEL_CHANGE notify type handling to the
3316 server. Affected file silcd/server.c.
3320 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Added silc_server_send_notify_invite to send the INVITE
3323 notify between routers.
3325 * Implemented the INVITE command correctly to the server.
3327 * Implemented the INVITE notify type handling in the server.
3329 * Implemented the INVITE command to the client library and on the
3332 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Added function silc_server_get_client_resolve to find the
3335 client entry by ID from all ID lists and then resolve it
3336 (using WHOIS) if it cannot be found. Affected file is
3339 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Implemented the BAN command to the client library.
3343 * The JOIN command in the server now checks the invite list
3346 * Changed the silc_command_reply_payload_encode_va and the
3347 silc_command_payload_encode_va to support that if argument is
3348 NULL it ignores and checks the next argument. Affected file
3349 lib/silccore/silccommand.c.
3351 * Added silc_server_send_notify_ban to send the BAN notify
3352 type between routers.
3354 * Chaned the silc_notify_payload_encode to support that if
3355 argument is NULL it ignores and checks the next argument.
3356 Affected file lib/silccore/silcnotify.c.
3358 * Tested ban lists in router environment successfully.
3360 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Implemented BAN command to the server, in silcd/command.[ch].
3364 * Removed the BAN and INVITE_LIST modes from the CMODE command
3367 * Added function silc_string_match to regex match two strings.
3368 Affected files lib/silcutil/silcutil.[ch].
3370 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Redefined parts of the SilcChannelEntry in the server to support
3373 the new ban and invite lists.
3375 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Redefined the INVITE command. The same command can be used to
3378 invite individuals to the channel but also to manage the invite
3379 list of the channel (to add to and remove from the invite list).
3380 Updated the protocol specs.
3382 * Added new command SILC_COMMAND_BAN that can be used to manage
3383 the ban list of the channel. Updated the protocol specs.
3385 * Removed the channel modes: the SILC_CMODE_BAN and the
3386 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3387 in the CMODE command. The equivalent features are now available
3388 using INVITE and BAN commands. Updated the protocol specs.
3390 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3391 in the network about change in the current ban list. The notify
3392 type is not used by the client.
3394 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3395 support the invite lists.
3397 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Added new function silc_string_regexify that converts string
3400 including wildcard characters into regex string that can
3401 be used by the GNU regex library. Added into the file
3402 lib/silcutil/silcutil.[ch].
3404 Added silc_string_regex_combine to combine to regex strings
3405 into one so that they can be used as one regex string by
3406 the GNU regex library. Added into the file
3407 lib/silcutil/silcutil.[ch].
3409 Added silc_string_regex_match to match two strings. It returns
3410 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3412 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Imported GNU regex to the soruce tree into lib/contrib.
3415 Fixed some compiler warning from the regex.c.
3417 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Fixed MOTD command in the server to work in router environment.
3421 * Fixed the MOTD command in the client library to support
3422 the server argument in the command.
3424 * Added `nickname_len' argument to the silc_idlist_add_client
3425 in the server, as the `nickname' argument may be binary data
3428 * Added silc_idlist_get_channels to return all channels from
3431 * Implemented LIST command to the server. Affected file is
3434 * Implemented the LIST command to the client library and on the
3437 * Added [<user count>] argument to the LIST command reply.
3438 With private channels the user count is not shown.
3440 * Updated TODO and README.
3442 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * The client entry's data.registered must be TRUE even with
3445 global client entry on global client list. The data.registered
3446 is used to check whether the client is anymore in the network,
3447 for example with WHOWAS command so it must be valid.
3449 * Fixed the WHOWAS command in the server. It now actually works
3450 in router environment. Added function into silcd/command_reply.c
3451 silc_server_command_reply_whowas_save.
3453 * Added silc_idlist_purge function to the silcd/idlist.c
3454 to periodically purge the ID Cache.
3456 * Fixed INFO command in the server. It works now in router
3457 environment. Added <server name> argument to the INFO command
3458 reply. Updated the protocol specs.
3460 * Fixed minor bug in silc_idcache_purge to not purge if the
3461 expire value is zero.
3463 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3464 they were buggy because of the WHOWAS information.
3466 * Fixed local command MSG to handle the async resolving of
3467 the remote client properly. It used to fail the first MSG.
3468 Affected file silc/local_command.c.
3470 * Added `data_len' field to SilcIDCache context.
3472 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Update TODO. Todo in commands in the server.
3476 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3479 used by routers as broadcast packet to inform other routers
3480 about the changed user mode.
3482 Implemented the notify handling in the server. Affected file is
3483 silcd/packet_receive.c. Added the function
3484 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3486 * Added new generic Channel Payload and deprecated the New Channel
3487 Payload. The New Channel Payload is now the generic Channel
3490 * Added new argument `mode' to the silc_server_send_new_channel
3491 as it is required in the Channel Payload now.
3493 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3494 and created a new and real SilChannelPayload to represent the
3495 new generic Channel Payload. Implemented the encode/decode
3496 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3498 * Added silc_server_get_client_channel_list to return the list
3499 of channels the client has joined for WHOIS command reply.
3500 Affected file silcd/server.[ch].
3502 * Implemented the channel list sending in the WHOIS command reply
3503 in server and in the client.
3505 Implemented the channel list displaying on the user interface
3506 as well. Affected file silc/client_ops.c.
3508 * Added silc_channel_payload_parse_list to parse list of Channel
3509 Payloads. It returns SilcDList list of SilcChannelPayloads.
3510 Client for example can use this function to parse the list of
3511 channels it receives in the WHOIS command reply. The caller
3512 must free the list by calling silc_channel_payload_list_free.
3513 Affected files lib/silccore/silcchannel.[ch].
3515 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Added one new argument <user mode> to the WHOIS command reply
3518 to return the mode of the user in SILC. Updated the protocol
3521 Implemented it to the server and client.
3523 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Fixed the mode printing on the user interface on joining.
3526 Affected file silc/client_ops.c.
3528 * Implemented the UMODE command and user modes in general to the
3529 client library and to the user interface.
3531 * Implemented the UMODE command to the server.
3533 * The server now sends UNKNOWN_COMMAND error status if client sends
3534 unknown command. Affected file silcd/command.c.
3536 * All server commands now handle the command identifier the right
3537 way when sending the command reply to the client. The client can
3538 use to identify the command replies with the identifier.
3540 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added silc_server_get_client_route to resolve the route to
3543 the client indicated by the client ID. Affected file is
3546 * Added silc_server_relay_packet as general function to relay
3547 packet to arbitrary destination. This deprecates functions
3548 like _send_private_message_key, _relay_notify etc. Affected
3549 file is silcd/packet_send.[ch].
3551 Removed silc_server_send_key_agreement,
3552 silc_server_send_private_message_key and
3553 silc_server_packet_relay_notify functions from the file
3554 silcd/packet_send.[ch].
3558 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3559 server. Affected file silcd/packet_receive.[ch].
3561 * Implemented the KILL command to the client. Implemented the
3562 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3563 Affected files lib/silcclient/command[_reply].c and
3564 lib/silcclient/client_notify.c. Implemented the KILL notify
3565 printing in the user inteface.
3567 * Fixed a lot silc_parse_nick memory leaks from the client
3568 library in the file lib/silcclient/command.c.
3570 * Changed the silc_server_send_notify_on_channels's `sender'
3571 argument from SilcSocketConnection to SilcClientEntry to
3572 check the sender as entry and not as connection object and not
3573 to send to the client provided as argument. The affected file
3574 is silcd/packet_send.[ch].
3576 * The notify packets that are destined directly to the client used
3577 to not to be processed by the server. Now changed that and the
3578 server processes all notify packets. After relaying the packet
3579 to the client the notify packet is processed in the server.
3581 * The silc_server_free_client_data now checks whether there is
3582 pending outgoing traffic for the client and purges the data to
3583 the network before removing the client entry.
3585 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3588 an client is killed from the SILC Network. Updated the protocol
3591 Added new function silc_server_send_notify_killed to the
3592 silcd/packet_send.[ch].
3594 * Added function silc_server_packet_relay_notify to relay notify
3595 packets that are destined directly to a client. In this case
3596 the server does not process the notify packets but merely relays
3597 it to the client. Affected file silcd/packet_send.[ch].
3599 Added also silc_server_packet_process_relay_notify to check
3600 whereto relay the notify. Affected file is
3601 silcd/packet_receive.[ch].
3603 * Implemented the KILL command to the server.
3607 * Added the backup schema desgined last fall to the protocol
3608 specs for everyone to see. The specification is in the
3609 *-spec-xx.txt draft and the packet type definitions for the
3610 backup routers is in *-pp-xx.txt draft. Thusly, added also
3611 new packet type SILC_PACKET_CELL_ROUTERS.
3613 * A big security problem in the implementation discovered. The
3614 signoff of an client did not cause new channel key generation
3615 which it of course should've done. The channel keys must be
3616 always re-generated when client leaves (or signoffs) the channel.
3617 The silc_server_remove_from_channels funtion now handles
3618 the channel key re-generation.
3620 * Added `sender' argument to the silc_server_send_notify_on_channels
3621 to not to send the client provided as argument. Affected file
3622 silcd/packet_send.[ch].
3624 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Implemented OPER and SILCOPER commands into the server and
3629 * Added silc_auth_verify and silc_auth_verify_data to verify
3630 the authentication directly from the authentication payload.
3631 It supports verifying both passphrase and public key based
3632 authentication. Affected file lib/silccore/silcauth.[ch].
3634 * Added `hash' field to the SilcIDListData structure. It is the
3635 hash negotiated in the SKE protocol. Affected file is
3638 * Slight redesigning of the SilcAuthPayload handling routines.
3639 Do not send SilcPKCS but SilcPublicKey as argument.
3641 * Implemented the public key authentication support to the
3642 serverconfig. The public key is loaded from the provided path
3643 and saved as authentication data to void * pointer. Thus,
3644 changed the unsigned char *auth_data to void *auth_data;
3646 * Fixed SHUTDOWN command to send the reply before the server
3647 is shutdown. :) Affected file silcd/command.c.
3649 * Fixed fatal bug in CONNECT command. The hostname was invalid
3650 memory and server crashed. Affected file silcd/command.c.
3652 * Fixed fatal bug in CLOSE command. The server_entry became
3653 invalid but was referenced later in the command. Affected file
3656 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Fixed fatal bug in failure packet handling. Server ignored
3659 the failure and thus crashed when it came.
3663 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3666 that the command may be executed only once in (about) 2 seconds.
3667 The old SILC_CF_LAG flag is same but allows command bursts up
3668 to five before limiting.
3670 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3671 server code. Various commands now includes the CF_LAG_STRICT
3672 flag to disallow any kind of miss-use of the command.
3674 * Fixed the silc_buffer_unformat to not to allocate any data
3675 if the length of the data is zero. It used to allocate the
3676 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3678 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Changed the format of AdminConnection configuration section
3681 in the server. Added username of the admin to the format.
3682 Affected files silcd/serverconfig.[ch].
3684 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3685 to return admin configuration data by host, username and/or
3688 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Implemented WHOWAS command to the server. Added the functions:
3692 silc_server_command_whowas_parse,
3693 silc_server_command_whowas_send_reply,
3694 silc_server_command_whowas_from_client and
3695 silc_server_command_whowas_from_server
3697 * Added <Client ID> argument to the WHOWAS command reply. Updated
3698 the protocol specs accordingly.
3700 * Implemented WHOWAS command and command_reply to the client
3703 Implemented the WHOWAS printing on the user interface.
3705 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Added new argument to the WHOWAS command reply, the real name.
3708 It is an optional argument. Updated the protocol specs.
3710 * Added SilcIDCacheDestructor callback that is registered when
3711 the SilcIDCache is allocated. The callback is called when
3712 an cache entry in the ID Cache expires, or is purged from the
3713 cache. Added into lib/silccore/idcache.[ch].
3715 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3716 to destruct the client entries when the cache entry expires.
3717 Other ID Cache's in server and in the client library ignores
3720 * If the ID Cache entry's `expire' field is zero then the entry
3721 never expires. Added boolean `expire' argument to the
3722 silc_idcache_add function in the lib/silccore/idcache.[ch].
3723 If it is TRUE the default expiry value is used.
3725 * Added silc_server_free_client_data_timeout that is registered
3726 when client disconnects. By default for 5 minutes we preserve
3727 the client entry for history - for WHOWAS command.
3729 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Added support to the server to enforce that commands are not
3732 executed more than once in 2 seconds. If server receives
3733 commands from client more frequently, timeout is registered
3734 to process the commands. Affected file silcd/command.c.
3735 Added new function silc_server_command_process_timeout.
3737 * Changed NICK_NOTIFY handling in client library to check that
3738 if the client's nickname was changed, so there is no need to
3739 resolve anything from the server.
3741 * Removed error printing from the WHOIS and IDENTIFY commands.
3742 If error occurs then it is ignored silently in the client library.
3743 The application, however, may map the received error to
3744 human readable error string. The application currently maps
3745 the NO_SUCH_NICKNAME error to string.
3747 * Made the command status message public to the application. Moved
3748 them from lib/silcclient/command_reply.c to
3749 lib/silcclient/command_reply.h. The application can map the
3750 received command status to the string with the
3751 silc_client_command_status_message function.
3753 * Added check to the server to check that client's ID is same
3754 as the Source ID in the packet the client sent. They must
3757 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3759 * Added dist-bzip hook to the Makefile.am to make bzip2
3760 compressed distributions.
3762 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Server now enforces the maximum length for the nickname and
3765 the channel as protocol specification dictates. 128 bytes for
3766 nickname and 256 bytes for channel name.
3768 * Moved the WHOIS printing to the application. The client libary
3769 does not print out the WHOIS information anymore, the application
3770 must do it. Renamed silc_client_command_reply_whois_print to
3771 the silc_client_command_reply_whois_save.
3773 The client's idle time is also sent to the application now, and
3774 the idle is shown on screen.
3776 * Added silc_client_command_reply_identify_save to save the
3777 received IDENTIFY entries.
3779 * Do not check for channel private keys in message sending and
3780 reception if the channel does not have the PRIVKEY mode set.
3781 Affected file lib/silclient/client_channel.c.
3783 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3786 just surfaced after chaning the JOIN procedure.
3788 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Added silc_client_get_clients_by_list to get client entries
3791 from Client ID list, that is returned for example by JOIN
3792 and USERS command replies. The application should use this
3793 function for example when JOIN command reply is received to
3794 resolve the clients already on the channel (library does not
3795 do that anymore as USERS command reply is not used in the JOIN
3796 procedure anymore). Affected files lib/silcclient/silcapi.h and
3797 lib/silcclient/idlist.c.
3799 * JOIN command reply and USERS command reply returns now SilcBuffer
3800 pointers instead of unsigned char pointers when returning
3801 the client list and mode list.
3803 * Added <Client ID> argument to the JOIN command reply, mainly
3804 for the server to identify for which client the command was
3805 originally sent. Updated protocol specs accordingly.
3807 * Added SilcDlist private_key pointer to the SilcChannelEntry
3808 in the client to support the channel private keys. Affected
3809 file is lib/silcclient/idlist.h.
3811 * Added SilcChannelPrivateKey argument to the function
3812 silc_client_send_channel_message so that application can choose
3813 to use specific private ke if it wants to. If it is not provided,
3814 the normal channel key is used, unless private keys are set.
3815 In this case the first (key that was added first) is used
3816 as the encryption key.
3818 * Implemented the support for channel private key handling.
3819 Implemented the following functions:
3821 silc_client_add_channel_private_key,
3822 silc_client_del_channel_private_keys,
3823 silc_client_del_channel_private_key,
3824 silc_client_list_channel_private_keys and
3825 silc_client_free_channel_private_keys
3827 Affected file lib/silcclient/client_channel.c.
3829 * Added the support for the private keys in the channel message
3830 sending and encryption and in the message reception and
3831 decryption. Affected funtions are
3832 silc_client_send_channel_message and silc_client_channel_message.
3834 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added SKE's key verify callback to the client library's
3837 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3839 * Removed the statement that server (or router) must send USERS
3840 command reply when joining to the channel so that the client
3841 knows who are on the channel. Instead, the client list and
3842 client's mode list is now sent in the JOIN command reply to the
3843 client who joined channel. This is better solution.
3845 * Added function silc_server_get_users_on_channel and function
3846 silc_server_save_users_on_channel to the silcd/server.[ch].
3848 * Removed function silc_server_command_send_users from the
3851 * Do not show topic on the client library anymore. The topic is
3852 sent in the command reply notify to the application and the
3853 application must show the topic now.
3855 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Added client searching by nickname hash into the IDENTIFY and
3858 WHOIS commands in the server as they were clearly missing from
3859 them. Affected file is silcd/command.c.
3861 * Fixed a bug in private message receiving in the client library.
3862 The remote ID was freed and it wasn't supposed, now it is
3865 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Minor fix to the channel payload; allocate the data area, as it
3868 needs to be of specific length.
3870 * If the key agreement port is zero then the operating
3871 system will define the bound port. Affected files are
3872 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3874 * Added new function silc_channel_payload_decrypt into the file
3875 lib/silccore/silcchannel.[ch].
3877 * Moved the channel message etc, check from silc_packet_decrypt
3878 to applications. The library calls now a generic
3879 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3880 when the packet is either normal or special. This was done to
3881 allow more wide range of checking that was not allowed when
3882 the code was in library. Now applications can do virtually any
3883 checks to the packet and return to the library the decision how
3884 the packet should be processed. Affected files are
3885 lib/silccore/silcpacket.[ch].
3887 Added silc_server_packet_decrypt_check to the server and
3888 silc_client_packet_decrypt_check to the client library.
3890 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3891 to send with specified source and destination information.
3893 * Channel message delivery between routers was broken after the
3894 channel key distribution was fixed earlier. The channel key
3895 was used be to distributed to other routers as well which is not
3896 allowed by the protocol. Now this is fixed and channel keys
3897 really are cell specific and the channel message delivery between
3898 routers comply with the protocol specification.
3900 * Fixed various commands in server to check also the global list
3901 for the channel entry and not just the local list. The affected
3902 file silcd/command.c.
3904 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Added assert()s to buffer formatting and unformatting routines
3907 to assert (if --enable-debug) when error occurs. Affected
3908 file: lib/silcutil/silcbuffmt.c.
3910 * Changed to auto-reconnect to check whether the remote host is
3911 router and register the re-connect timeout if it is. It used
3912 to check that whether we are normal server, but router must do
3913 auto-reconnect with another router as well. Affected file
3916 * Removed the [<key len>] option from CMODE command as the cipher
3917 name decides the key length, nowadays. See the defined ciphers
3918 from the protocol specification.
3920 * Added [<hmac>] option to the CMODE command to define the HMAC
3921 for the channel. Added SILC_CMODE_HMAC channel mode.
3923 * Added [<hmac>] option for the JOIN command so that user can
3924 select which HMAC is used to compute the MACs of the channel
3927 * Added Hmac field to the Channel Message Payload. The integrity
3928 of plaintext channel messages are now protected by computing
3929 MAC of the message and attaching the MAC to the payload. The
3930 MAC is encrypted. Now, it is clear that this causes some
3931 overhead to the size of the packet but rationale for this is that
3932 now the receiver can verify whether the channel message decrypted
3933 correctly and also when private keys are set for the channel the
3934 receiver can decrypt the packet with several keys and check from
3935 the MAC which key decrypted the message correctly.
3937 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3938 lib/silccrypt/silccipher.[ch].
3940 * Added silc_hash_len to return the digest length into the
3941 lib/silcrypt/silchash.[ch].
3943 * Rewrote parts of Silc Channel Payload interface in the
3944 lib/silccore/silcchannel.[ch]. The encode function now also
3945 encrypts the packet and parse function decrypts it.
3947 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Fixed a minor formatting bug in the SKE's key material processing.
3950 It actually might have processed the keys wrong way resulting
3953 * Redefined the mandatory HMAC algorithms and added new algorithms.
3954 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3955 and hmac-md5 truncated to 96 bits. The mandatory is now
3956 hmac-sha1-96. Rest are optional (including the one that used
3957 to be mandatory). Rationale for this is that the truncated HMAC
3958 length is sufficient from security point of view and can actually
3959 make the attack against the HMAC harder. Also, the truncated
3960 HMAC causes less overhead to the packets. See the RFC2104 for
3963 * Added new [hmac] configuration section. The SKE used to use
3964 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3965 is of course wrong. The official names that must be proposed in
3966 the SKE are the ones defined in the protocol specification
3967 (hmac-sha1-96 for example). The user can configure any hmac
3968 using any hash function configured in the [hash] section. At
3969 least, the mandatory must be configured.
3971 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3973 * Added HMAC list to the SKE proposal list. It has now both
3974 hash algorithm list and HMAC list. This makes the protocol
3975 incompatible with previous versions. The SKE now seems to work
3976 the way it is supposed to work, for the first time actually.
3978 * Defined plain Hash algorithms to the protocol specification.
3981 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Implemented support for key agreement packets into the server.
3984 Added functions silc_server_key_agreement and
3985 silc_server_send_key_agreement. Other than these functions,
3986 server has nothing to do with this packet.
3988 * Added support for private message key packets into the server.
3989 Added functions silc_server_private_message_key and
3990 silc_server_send_private_message_key.
3994 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3995 called in the protocol's final callback instead in the END
3996 protocol state. This makes a little more sense and in the same
3997 time in client we can use the same protocol routines for normal
3998 key exchange and to key agreement packet handling as well.
4000 * Added to both client's and server's KE protocol context the
4001 SilcSKEKeyMaterial pointer to save the key material. We will
4002 bring the key material to the protocol's final callback by doing
4003 this. The final callback must free the key material.
4005 * Added SKE's packet_send callback into client's KE protocol
4006 context so that the caller can choose what packet sending function
4007 is used. This way we can use different packet sending when
4008 doing normal SKE when doing key agreement packet handling (in
4009 the key agreement packet handling we do not want to encrypt
4012 * Implemented the responder side of the key agreement routines
4013 in the client. The client can now bind to specified port and
4014 accept incoming key negotiation. The key material is passed
4015 to the application after the protocol is over.
4017 * Implemented the processing of incoming Key Agreement packet
4018 in the client. Added function silc_client_key_agreement to
4021 * Implemented the intiator side of the key agreement routines
4022 in the client. The client can now initiate key agreement with
4023 another remote client. The key material is passed to the
4024 application after the protocol is over.
4026 * Created client_keyagr.c to include all the key agreement
4029 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4030 SILC_TASK_CALLBACK except that it is not static.
4032 * Created client_notify.c and moved the Notify packet handling
4033 from the client.[ch] into that file.
4035 * Created client_prvmsg.c and moved all private message and
4036 private message key routines from the client.[ch] into that file.
4038 * Create client_channel.c and moved all channel message and
4039 channel private key routines from the client.[ch] into that file.
4041 * Changed silc_client_get_client_by_id_resolve to resolve with
4042 WHOIS command instead of IDENTIFY command, in the file
4043 lib/silclient/idlist.c.
4045 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Implemented the SKE's responder side to the Client library.
4049 * When FAILURE is received to the protocol do not trust it
4050 blindly. Register a timeout to wait whether the remote closes
4051 the connection as it should do it, only after that process the
4052 actual failure. This was changed to both client and server.
4054 * Added client_internal.h to include some of the structures
4055 there instead of client.h in lib/silcclient/.
4057 * Added function silc_task_unregister_by_callback to unregister
4058 timeouts by the callback function.
4060 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Some "Incomplete WHOIS info" errors has been appearing on the
4063 log files. Took away the entry->userinfo check from WHOIS
4064 reply sending. The entry->userinfo is now " " if client did not
4065 provide one. I thought this was fixed earlier but something
4066 is wrong still. Let's see if the error still appears.
4068 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Fixed a minor bug in the login when the channel key is
4071 re-generated in the server. It used to generate the key in
4072 wrong order and thus caused problems in the channel traffic.
4074 * Fixed a minor bug in channel key distsribution after
4075 KICK command. The key was not sent to the router even though
4078 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Added silc_ske_process_key_material_data as generic routine
4081 to process any key material as the SILC protocol dictates. The
4082 function is used by the actual SKE library but can be used by
4083 applications as well. This relates to the private message keys
4084 and the channel private keys since they must be processed the
4085 same way the normal SILC session keys. The protocol dictates
4086 this. Affected files: lib/silcske/silcske.[ch].
4088 Added also silc_ske_free_key_material to free the
4089 SilcSKEKeyMaterial structure.
4091 * Defined silc_cipher_set_key function to set the key for
4092 cipher without using the object's method function. The affected
4093 files: lib/silccrypt/silccipher.[ch].
4095 * Implemented silc silc_client_add_private_message_key,
4096 silc_client_add_private_message_key_ske,
4097 silc_client_del_private_message_key,
4098 silc_client_list_private_message_keys and
4099 silc_client_free_private_message_keys functions in the
4102 Added functions silc_client_send_private_message_key to send
4103 the Private Message Key payload and silc_client_private_message_key
4104 to handle incoming Private Message Key payload.
4106 * Added Cipher field to the Private Message Key payload to set
4107 the cipher to be used. If ignored, the default cipher defined
4108 in the SILC protocol (aes-256-cbc) is used.
4110 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * Removed lib/silcclient/ops.h file.
4114 Redefined parts of the SILC Client Library API. Created new
4115 file silcapi.h that deprecates the ops.h file and defines the
4116 published Client Library API. Defined also private message key
4117 API and channel private key API into the file.
4119 This is the file that the application must include from the
4120 SILC Client Library. Other files need not be included by
4121 the application anymore.
4123 * Added new key_agreement client operation callback and also
4124 defined the Key Agreement library API for the application.
4126 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4129 is used by clients to request key negotiation between another
4130 client in the SILC network. If the negotiation is started it
4131 is performed using the SKE protocol. The result of the
4132 negotiation, the secret key material, can be used for example
4133 as private message key.
4135 Implemented the Key Agreement payload into the files
4136 lib/silccore/silauth.[ch].
4138 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Redefined ciphers for the SILC protocol. Added some new ciphers
4141 and defined the key lengths for the algorithms. Changed the
4142 code accordingly. The default key length is now 256 bits.
4144 * Fixed SKE key distribution function silc_ske_process_key_material
4145 when the key length is more than 128 bits. The default key
4146 length in SILC is now 256 bits.
4148 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4149 to indicate unsupported algorithm.
4151 * Renamed rijndael.c to aes.c and all functions as well.
4153 * Fixed a long standing channel key setting bug in client library.
4154 Weird that it has never surfaced before.
4156 * Fixed bug in channel deletion. If the entire channel is removed
4157 then it must also delete the references of the channel entry
4158 from the client's channel list as the client's channel entry and
4159 the channel's client entry share same memory.
4161 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Implemented CONNECT and SHUTDOWN commands in the client.
4165 * Implemented CLOSE command to the client.
4167 * Added the function silc_idlist_find_server_by_name into the
4168 files silcd/idlist.[ch].
4170 Added the function silc_idlist_find_server_by_conn into the
4171 files silcd/idlist.[ch].
4173 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * DIE command was renamed to SHUTDOWN. Updated the both code
4178 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4179 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4181 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4184 * Added function silc_server_create_connection function to create
4185 connection to remote router. My server implementation actually
4186 does not allow router to connect to normal server (it expects
4187 that normal server always initiates the connection to the router)
4188 so the CONNECT command is only good for connecting to another
4191 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4194 or some other client was kicked from the channel.
4196 Implemented the handling of the notify type to both client
4199 Implemented silc_server_send_notify_kicked to send the KICKED
4200 notify. It is used to send it to the server's primary router.
4202 * Implemented the KICK command into server and client.
4204 * Added `query' argument to the silc_idlist_get_client function
4205 to indicate whether to query the client from server or not if
4208 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4209 to indicate that the client is not channel founder.
4213 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Removed the rng context from SilcPacketContext structure and
4216 changed that the packet routine uses the Global RNG API.
4218 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Added support for quit message that client can "leave" on the
4221 channel when it quits the SILC. It is ditributed inside the
4222 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4224 Added silc_server_free_client_data that will take the
4225 signoff message as argument.
4227 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4229 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Updated parts of the protocol specification to keep it up
4234 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4237 payloads in one packet.
4239 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4240 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4241 use now the new List flag.
4243 * Also deprecated the following packet types: REPLACE_ID,
4244 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4246 * Added list support for Notify packet in server.
4248 * Added silc_server_send_notify_channel_change to send the
4249 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4250 the silc_server_send_replace_id.
4252 * Added silc_server_send_notify_nick_change to send the
4253 NICK_CHANGE notify type. Deprecates the function
4254 silc_server_send_replace_id.
4256 * Added silc_server_send_notify_join to send the JOIN notify type.
4257 Deprecates the function silc_server_send_new_channel_user.
4259 * Added silc_server_send_notify_leave to send LEAVE notify type.
4260 Deprecates the function silc_server_send_remove_channel_user.
4262 * Added silc_server_send_notify_cmode and
4263 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4264 types. Deprecates the silc_server_send_set_mode function.
4266 * Added SERVER_SIGNOFF notify type to indicate that server has
4267 quit. This means that all clients on the channel from that
4268 server will drop. This can be also used when netsplit happens.
4270 Deprecated REMOVE_ID packet type since it is not needed anymore
4273 Added silc_server_send_notify_server_signoff to send the
4274 SERVER_SIGNOFF notify type. Deprecates the function
4275 silc_server_send_remove_id.
4277 Added also silc_server_send_notify_signoff to send the
4278 SIGNOFF notify type.
4280 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4281 SILC protocol from this day on. Changed the protocol
4282 specification as well.
4284 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4285 notify type. It is used between routers to notify about
4286 topic changes on a channel.
4288 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4291 * Partly updated the protocol specification to comply with the
4292 changes now made. It is still though a bit outdated.
4294 * The JOIN notify type now takes one extra argument <Channel ID>.
4295 The packet used to be destined to the channel but now the
4296 JOIN type may be sent as list thus it is impossible to
4297 destine it to any specific channel. By adding this argument
4298 it is again possible.
4300 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Added CREDITS file. The CHANGES and CREDITS file will appear
4303 in the distribution as well.
4305 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4308 types in the server's silcd/packet_receive.c.
4310 * Implemented CMODE and CUMODE to work in router environment.
4312 * Fixed minor encoding and decoding buglet from the
4313 lib/silccore/silcmode.c.
4315 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4318 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4320 * Changed all SilcConfigServer* and silc_config_server* to
4321 SilcServerConfig* and silc_server_config*, respectively.
4324 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Associated the ID (client or server ID) to the Authentication
4327 Payload to avoid any possibility of forging. Updated the
4328 protocol specification and the code accordingly.
4330 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * The RSA key length is now save to the RsaKey context in the
4333 key generation process in lib/silccrypt/rsa.c. The key length
4334 is now used to figure out the maximum size of the block allowed
4335 to be encrypted/signed.
4337 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4338 is equivalent to the silc_mp_mp2bin but does not allocate any
4341 * Changed silc_mp_mp2bin API to take length argument. If it is
4342 non-zero then the buffer is allocated that large. If zero, then
4343 the size is approximated using silc_mp_sizeinbase, which however
4346 * Created Global RNG API which is global RNG that application can
4347 initialize. After initializing, any routine anywhere in the
4348 code (including library) can use RNG without allocating a new
4349 RNG object. This was done to allow this sort of use of the
4350 RNG in code that has no chance to allocate RNG object. All
4351 applications currently allocate this and many routines in the
4352 library use this. Affected file lib/silccrypt/silcrng.[ch].
4354 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4355 it to use the Global RNG API.
4357 * Defined Authentication Payload into protocol specification that
4358 is used during SILC session to authenticate entities. It is
4359 used for example by client to authenticate itself to the server
4360 to obtain server operator privileges.
4362 Implemented this payload into the lib/silccore/silcauth.[ch].
4363 Implemented also routines for public key based authentication
4364 as the new protocol specification dictates.
4366 Moved definitions of different authentication methods from
4367 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4369 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4370 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4371 silc_pkcs_verify_with_hash functions into the file
4372 lib/silccrypt/silcpkcs.[ch].
4374 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * The client entry's userinfo pointer must be always valid.
4377 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4378 will fail since it requires the userinfo. Now, the userinfo
4379 is allocated as "" if actual userinfo does not exist. Actually,
4380 it must exist and it is totally Ok to drop client connections
4381 that does not announce the userinfo. However, we will make
4382 this workaround for now.
4384 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4385 to return the remote port by socket.
4387 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4390 SILC_SERVER_PENDING_EXEC and added an new macro
4391 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4392 data or when error occurs while processing the pending command.
4394 Added new argument `destructor' into silc_server_command_pending
4395 and to the SilcServerCommandPending object. This destructor is
4396 now called after calling the pending callback or if error occurs
4397 immediately. If error occurs the actual pending callback won't
4398 be called at all - only the destructor. The destructor may be
4399 NULL if destructor is not needed.
4401 All this applies for client library code as well. Similar
4402 changes were made there as well for the pending commands.
4404 In the client, the application must now allocate the
4405 SilcClientCommandContext with the silc_client_command_alloc
4408 * Added reference counter to the SilcServerCommandContext. Added
4409 function silc_server_command_alloc and silc_server_command_dup
4412 Same type of functions added to the client library for the same
4415 * Removed the cmd_ident from IDListData away since it is now
4416 global for all connections. It is the command identifier used
4417 in command sending and with pending commands. The affected file
4420 * Added reference counter to the SilcSocketConnection objecet to
4421 indicate the usage count of the object. The object won't be
4422 freed untill the reference counter hits zero. Currently only
4423 server uses this, and client ignores it. The client must be
4424 set to use this too later. The affected files are
4425 lib/silccore/silcsockconn.[ch]. Added also the function
4426 silc_socket_dup to increase the reference counter.
4428 This was mainly added because it is possible that the socket
4429 is removed underneath of pending command or other async
4430 operation. Now it won't be free'd and proper DISCONNECTING
4431 flags, etc. can be set to avoid sending data to connection that
4432 is not valid anymore.
4434 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4435 the connection. After that it sets SILC_SET_DISCONNECTED.
4436 It is, however, possible that the socket data is not still freed.
4437 The silc_server_packet_process now checks that data is not
4438 read or written to connection that is DISCONNECTED. The socket
4439 get's freed when the reference counter hits zero.
4441 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Changed the client operation API: channel_message operation's
4444 `sender' is now the client entry of the sender, not the nickname
4445 and the `channel' is the channel entry, not the channel name.
4447 In the private_message operation the `sender' is now also the
4448 client entry of the sender not the nickname.
4450 Affected file is lib/silcclient/ops.h and all applications
4451 using the client operations.
4453 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Moved the calling of ops->connect() from connect_to_server_final
4456 into receive_new_id functin since that is the point when the
4457 client is actually allowed to send traffic to network. The
4458 affected file is lib/silcclient/client.c.
4460 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4463 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4464 (if needs broadcasting) instead of broadcasting the packets one
4465 by one which would make a burst in the network traffic.
4467 * Added `broadcast' argument to the functions in silcd/server.[ch]
4468 silc_server_create_new_channel[_with_id] to indicate whether
4469 to send New Channel packet to primary router.
4471 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added new function into the silcd/server.[ch] files:
4474 silc_server_create_new_channel_with_id to create new channel with
4475 already existing Channel ID.
4477 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4478 lib/silccore/silcpacket.h. This packet is used t send list of
4479 Set Mode payloads inside one packet. Server uses this to set
4480 the modes for the channels and clients on those channels, that it
4481 announced to the router when it connected to it. The protocol
4482 specification has been updated accordingly.
4484 * The silc_server_new_channel did not handle the packet coming
4485 from normal server as it normally does not send that. However,
4486 when it announces its channels it does send it. Implemented
4487 the support for that.
4489 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4490 into the file lib/silccore/id.h.
4492 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Fixed memory leaks in the functions silc_idlist_del_client,
4495 silc_idlist_del_channel and silc_idlist_del_server in the file
4496 silcd/idlist.c. All of those leaked like a sieve.
4498 * Fixed some small memory leaks in the client's function
4499 silc_client_notify_by_server.
4501 * Added functions into silcd/server.c: silc_server_announce_clients,
4502 silc_server_announce_channels and silc_server_announce_server.
4503 These functions are used by normal and router server to announce
4504 to its primary router about clients, channels and servers (when
4505 router) that we own. This is done after we've connected to the
4508 These functions effectively implements the following packet types:
4509 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4510 and SILC_PACKET_NEW_ID_LIST.
4512 * Added new functions into the silcd/packet_receive.[ch]:
4513 silc_server_new_id_list, silc_server_new_channel_list and
4514 silc_server_new_channel_user_list to handle the incoming
4515 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4517 * Added support of changing Channel ID in the function
4518 silc_server_replace_id. If the server that announces a channel
4519 to the router already exists in the router (with same name but
4520 with different Channel ID), router is responsible to send
4521 Replace ID packet to the server and force the server to change
4522 the Channel ID to the one router has.
4524 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4525 client that the Channel ID has been changed by the router. The
4526 normal server sends this to the client. Client must start using
4527 the new Channel ID as the channel's ID.
4529 Implemented handling of this new type into lib/silcclient/client.c
4530 into the function silc_client_notify_by_server.
4532 * Added new function silc_idlist_replace_channel_id into the files
4533 silcd/idlist.[ch] to replace the Channel ID.
4535 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Call silc_server_command_identify_check always when processing
4538 the IDENTIFY command in silcd/command.c
4540 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4543 send keepalive packets. The packet can be sent by clients,
4544 servers and routers.
4546 Added function silc_socket_set_heartbeat into the file
4547 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4548 If not set, the heartbeat is not performed. The actual
4549 heartbeat is implemented in the low level socket connection
4550 library. However, application is responsible of actually
4553 Added silc_server_send_heartbeat to send the actual heartbeat
4554 packet into silcd/packet_send.[ch]. Server now performs
4555 keepalive with all connections.
4557 * Added silc_task_get_first function into lib/silcutil/silctask.c
4558 to return the timeout task with shortest timeout. There was a bug
4559 in task unregistration that caused problems. TODO has been
4560 updated to include that task system must be rewritten.
4562 * The client library will now resolve the client information when
4563 receiving JOIN notify from server for client that we know but
4564 have incomplete information.
4566 * Rewrote parts of silc_server_remove_from_channels and
4567 silc_server_remove_from_one_channel as they did not remove the
4568 channel in some circumstances even though they should've.
4570 * Encryption problem encountered in server:
4572 The LEAVE command used to send the Channel Key packet to the
4573 router immediately after generating it. However, the code
4574 had earlier sent Remove Channel user packet but not immediately,
4575 ie. it was put to queue. The order of packets in the router
4576 was that Channel Key packet was first and Remove Channel User
4577 packet was second, even though they were encrypted in the
4578 reverse order. For this reason, MAC check failed. Now, this
4579 is fixed by not sending the Channel Key packet immediately but
4580 putting it to queue. However, this is more fundamental problem:
4581 packets that are in queue should actually not be encrypted
4582 because packets that are sent immediately gets encrypted
4583 actually with wrong IV (and thus MAC check fails). So, packets
4584 that are in queue should be encrypted when they are sent to
4585 the wire and not when they put to the queue.
4587 However, the problem is that the current system has not been
4588 designed to work that way. Instead, the packet is encrypted
4589 as soon as possible and left to the queue. The queue is then
4590 just purged into wire. There won't be any fixes for this
4591 any time soon. So, the current semantic for packet sending
4594 o If you send packet to remote host and do not force the send
4595 (the packet will be in queue) then all subsequent packets to the
4596 same remote host must also be put to the queue. Only after the
4597 queue has been purged is it safe again to force the packet
4600 o If you send all packets immediately then it safe to send
4601 any of subsequent packets through the queue, however, after
4602 the first packet is put to queue then any subsequent packets
4603 must also be put to the queue.
4605 Follow these rules and everything works fine.
4607 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Added new function silc_server_remove_clients_by_server to
4610 remove all client entries from ID list when the server connection
4611 is lost. In this case it is also important to invalidate all
4612 client entires as they hold the invalid server entry. This
4613 fixes fatal bug when server has lost connection and will reconnect
4616 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Made some sanity checks to silc_server_daemonise like to check
4619 whether the requested user and group actually exists.
4621 * Added sanity check to SKE's silc_ske_responder_finish to check
4622 that the public and private key actually is valid.
4624 * Invalidate the client's nickname when receiving Replace ID
4625 packet and the Client ID is being replaced. This means that the
4626 server will query the nickname if someone needs it (client)
4629 * Sort the ID Cache in client library when the ID Cache data
4630 has changed (needs sorting).
4632 * Do not allow for SILC client to create several connections to
4633 several servers. The client does not support windows right now
4634 and generating multiple connections causes weird behaviour.
4636 Irssi-silc client does support windows and can handle several
4637 connections without problems, see: www.irssi.org and SILC plugin.
4639 * Fixed some places where client was added to the IDList. The
4640 rule of thumb is following (in order to get everything right):
4641 If the client is directly connected local client then the
4642 `connection' argument must be set and `router' argument must be
4643 NULL to silc_idlist_add_client function. If the client is not
4644 directly connected client then the `router' argument must
4645 bet set and the `connection' argument must be NULL to the
4646 silc_idlist_add_client function.
4648 * The funtion silc_server_packet_send_local_channel actually did
4649 not check whether the client was locally connected or not. It
4650 does that now. Fixed a bug related to LEAVE command.
4652 * Fixed Remove Channel User payload parsing bug in server's
4653 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4655 * The server's silc_server_save_channel_key now checks also the
4656 global ID list for the channel as it might not be in the local
4657 list. Fixed a bug related to LEAVE command.
4659 * Is this the end of the [<unknown>] buglet that has been lurking
4660 around for a long time? A little for loop fix in server's
4661 silc_server_command_whois_parse that is used by both IDENTIFY
4662 and WHOIS command. At least, this was a clear bug and a cause
4663 of one type of [<unknown>] buglet.
4665 * WHOIS and IDENTIFY commands call the function
4666 silc_server_command_[whois/identify]_check function even if
4667 we are not router server.
4669 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Added --with-gmp configuration option. If set the GMP
4672 is always compiled in the SILC source tree. If not set then
4673 it is checked whether the system has the GMP3 installed. If
4674 it has then the GMP won't be compiled (the system's headers
4675 and library is used), if it doesn't have it then the GMP is
4676 compiled in the SILC source tree.
4678 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Changed RSA private exponent generation to what PKCS #1
4681 suggests. We try to find the smallest possible d by doing
4682 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4683 not security fix but optimization.
4685 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Added new config entry [Identity] to fork the server and run
4688 it as specific user and group. A patch from Bostik.
4690 * Imported Dotconf configuration library into lib/dotconf.
4691 This will be used to create the SILC configuration files later.
4692 It will appear in the distsribution after this commit.
4694 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * A big code auditing weekend happening. Auditing code for
4697 obvious mistakes, bugs and errors. Also, removing any code
4700 Removed files for being obsolete:
4702 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4703 inline in the file lib/silcutil/silcbuffer.h)
4705 o lib/silcutil/silcbufutil.c (the header has inline versions)
4707 Changed code to fix possible error conditions:
4709 o The buffer formatting routines now check that the destination
4710 buffer really has enough space to add the data. This applies for
4711 both buffer formatting and unformatting
4712 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4713 unformatting was changed to accomodate following rules:
4714 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4715 sent to the function while XXX_*STRING will not allocate or copy
4716 the data into the buffer. Instead it sets the pointer from the
4717 buffer into the pointer sent as argument (XXX_*STRING used to
4718 require that the pointer must be allocated already). This change
4719 makes this whole thing a bit more consistent and more optimized
4720 (note that the data returned in the unformatting with XXX_*STRING
4721 must not be freed now). The routines return now -1 on error.
4723 o Tried to find all code that use buffer_format and buffer_unformat
4724 and added return value checking to prevent formatting and
4725 especially unformatting errors and possible subsequent fatal
4728 o Changed ske->x and ske->KEY to mallocated pointers in
4729 lib/silcske/silcske.h. Fixed possible data and memory leak.
4731 o Added return value checking to all *_parse* functions. Fixed
4732 many memory leaks as well.
4734 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4735 so that buffer overflows would not happen. All code now also
4736 checks the return value as it can fail.
4738 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added reconnection support to server if the normal server looses
4741 its connection to the router (for example if router is rebooted).
4742 The server performs normal reconnection strategy implemented
4743 to the server. Affected file silcd/server.c.
4745 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Added new packet type SILC_PACKET_SET_MODE that is used to
4748 distribute the information about changed modes (for clients,
4749 channels and clients channel modes) to all routers in the
4750 network. Updated the protocol specification accordingly.
4752 Added functions into silcd/packet_send.c and
4753 silcd/packet_receive.c: silc_server_send_set_mode,
4754 silc_server_set_mode.
4756 Added new files silcmode.[ch] into lib/silccore that implements
4757 the encoding and decoding of Set Mode Payload. Added new type
4758 SilcSetModePayload. Moved the definitions of different modes
4759 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4761 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Oops, a little mistake in server's connection authentication
4764 protocol. The protocol is not ended with FAILURE but with
4765 SUCCESS if the authentication is Ok. :) Affected file is
4768 * Implemented NICK_CHANGE notify handling in server in the file
4769 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4770 the local clients on the channel. After the changing nickname
4771 in router environment snhould work and the [<unknown>] nickname
4772 should appear no more.
4774 The silc_server_replace_id function that receives the Replace ID
4775 payload now sends the NICK_CHANGE notify type also in the file
4776 silcd/packet_receive.c
4778 * Changed WHOIS and IDENTIFY command to support the maximum amount
4779 of arguments defined in protocol specs (3328 arguments). This
4780 fixed a bug that caused problems when there were more than three
4783 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Added extra parameter, command identifier, to the
4786 silc_client_send_command so that explicit command identifier
4789 Changed that ID list routines uses specific command identifier
4790 when sending WHOIS/IDENTIFY requests to the server so that they
4791 can be identified when the reply comes back.
4793 Affected files lib/silcclient/command.[ch],
4794 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4796 * Added `sender' argument to silc_server_packet_send_to_channel
4797 to indicaet the sender who originally sent the packet to us
4798 that we are now re-sending. Ignored if NULL. Affected file
4799 silcd/packet_send.[ch].
4801 * Added some server statistics support in silcd/server_internal.h
4802 SilcServerStatistics structure and around the server code. Also
4803 send some nice statistics information when client is connecting
4806 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Fixed channel ID decoding in server's JOIN command reply in
4809 silcd/command_reply.c
4811 * Fixed braodcasting of replace ID payload to not to send it if
4812 we are standalone server in silcd/packet_receive.c.
4814 * Fixed all channel message sending routines to not to send
4815 packets to clients that has router set, since they are routed
4816 separately in the same function earlier. Affects file
4817 silcd/packet_send.c and all channel packet sending functions.
4819 * In USERS reply, res_argv[i] are not allocated, the table
4820 is allocated. Thus changed that free the table, not its
4823 * In server's whois_check and identify_check if the client is
4824 locally connected do not send any WHOIS commands - they are not
4827 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Fixed some minor bugs in client when sending WHOIS command. The
4830 arguments was in wrong order.
4832 * Removed statis function add_to_channel from server in
4833 silcd/command.c that was previously used with the joining but
4836 * Tested USERS command in router environment successfully with two
4837 routers, two servers and two clients.
4839 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Reorganized the USERS command and command reply in client library
4842 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4843 When the command is given by user we register a pending command
4844 callback that will reprocess the command after the reply has been
4845 received from the server. When reprocessing the packet we then
4846 display the information. Thus, the USERS information is displayed
4847 now in the command callback instead of in the command reply
4848 callback. The processing of the command is same as previously
4849 when server has sent the command reply in the JOINing process.
4851 * Added to USERS command in silcd/command_reply.c to join the client,
4852 we didn't use to know about, to the channel after we've created
4853 a client entry for it. Also, for clienet we did know already still
4854 check whether it is on the channel or not and add it if not.
4856 * Removed silc_server_command_join_notify as the function and its
4859 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Changed the client's pending command handling to the same as the
4862 server's pending command handling. It is also now possible to
4863 execute command reply functions from other command reply
4864 function as the function callbacks for commands and command
4865 replies are one and same. The pending commands are not static
4866 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4867 in client connection context. Thus, pending commands are server
4868 connection specific as it is convenient.
4870 Changed the function silc_client_command_pending and
4871 silc_client_command_pending_del and added new function
4872 silc_client_command_pending_check. Removed the
4873 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4876 * Added cmd_ident, current command identifier, to the client
4877 connection context in lib/silcclient/client.h to keep track on
4878 command identifiers used in command sending. Client's command reply
4879 function handling now supports the mandatory command identifiers.
4881 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4882 funtions in client to fully support pending command callbacks.
4884 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4885 as one of the arguments to the application in the command reply
4888 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4889 before first releasing SILC but came back. Now it is removed again
4890 and should come back nomore. The FORWARDED flag was used only
4891 by the JOINing procedure by forwarding the command packet to router.
4892 Now, the JOINing procedure has been changed to more generic (due
4893 to various router environment issues) and FORWARDED is not needed
4894 anymore for anything. The protocol specification is yet to be
4897 Now, removed silc_server_packet_forward from server and the flag
4898 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4900 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Renamed NAMES command to USERS command. The NAMES was named that
4903 due to historical reasons. Now it is renamed. Also, rewrote
4904 parts of the USERS command. The nickname list is not sent anymore
4905 by the server. Only Client ID and mode lists are sent in the USERS
4906 command. Changed this also to the protocol specification.
4908 The client now resolves the names and stuff after it receives
4909 the USERS list from the server when joining to the channel.
4911 * WHOIS and IDENTIFY commands has been changed to support multiple
4912 Client ID's per command. One can now search for multiple users
4913 in the network by sending only one WHOIS or IDENTIFY command.
4914 Changed the code and the protocol specifications.
4916 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4917 uses silc_server_command_whois_parse to parse the request. */
4919 * If normal server, do not parse the WHOIS and IDENTIFY requests
4920 before sending it to the router. Saves some time.
4922 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Fixed JOIN command on client library. Wrong number of arguments
4925 used to crash the client.
4927 * Added silc_server_channel_has_global function to check whether
4928 channel has global users or not.
4930 * Added silc_server_channel_has_local function to check whether channel
4931 has locally connected clients on the channel.
4933 * The silc_server_remove_from_one_channel now checks whether the
4934 channel has global users or not after given client was removed from
4935 the channel. It also checks whether the channel has local clients
4936 on the channel anymore. If it does not have then the channel entry
4937 is removed as it is not needed anymore.
4939 * The silc_server_notify now checks on JOIN notify whether the joining
4940 client is one of locally connected or global. If it is global then
4941 the channel has now global users on the channel and that is marked
4942 to the channel entry. Also, it now saves the global client to
4943 global list who is joining and JOINs it to the channel. This is
4944 for normal server, that is.
4946 Changed silc_server_send_notify_on_channel,
4947 silc_server_packet_relay_to_channel and
4948 silc_server_packet_send_to_channel check if we are normal server
4949 and client has router set (ie. global client) do not send the
4950 message to that client, as it is already routed to our router.
4952 * Implemented LEAVE notify type handling in silc_server_notify
4955 * Tested LEAVE command in router environment successfully. Tested
4956 with two routers, two servers and two clients.
4960 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4962 * Implemented SIGNOFF notify type handling in silc_server_notify
4965 * silc_server_remove_id now removes the client entry from all channels
4966 it has joined and thusly sends SIGNOFF notify type.
4968 * Rewrote the NAMES list generation in server by removing two excess
4969 loops. The lists are created now inside one loop.
4971 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * silc_server_remove_channel_user checks now also global list
4974 for channel and client.
4976 * silc_server_new_channel_user checks now both local and global
4977 list for channel and client. Fixed a bug in client id decoding.
4978 Used to decode wrong buffer.
4980 * silc_server_channel_message checks now both local and global
4981 list for channel entry.
4983 * Tested channel joining (hence JOIN) in router environment
4984 successfully. Tested with two routers, two servers and two
4987 * Tested channel message sending in router environment successfully.
4989 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added silc_server_save_channel_key into server.[ch] to save the
4992 received channel key in Channel Key payload processing. It is
4993 also used in JOIN command reply handling.
4995 Equivalent function silc_client_save_channel_key added into
4996 client.[ch] into client library.
4998 * Changed JOIN command reply to send information whether the channel
4999 was created or not (is existing already) and the channel key
5000 payload. Changed protocol specs accordingly.
5002 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5003 the request was sent by ID and not by nickname. Crashed on
5006 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5009 now correctly save the received data.
5011 * silc_server_free_sock_user_data now notifies routers in the
5012 network about entities leaving the network.
5014 At the same time implemented functions silc_server_remove_id
5015 and silc_server_send_remove_id to receive and send REMOVE_ID
5016 packets. The packet is used to notify routers in the network
5017 about leaving entities. The ID removed will become invalid in
5020 * Added function silc_idlist_del_server into server. Removes and
5021 free's server entry from ID list.
5023 * silc_server_private_message function now checks, if we are router,
5024 that the destination ID really is valid ID, naturally.
5026 * In router when NEW_ID packet is received (for new client) the
5027 hash of the Client ID is saved in the ID Cache but the
5028 client->nickname is set to NULL, instead of putting the hash
5031 IDENTIFY command now also checks that client->nickname must be
5032 valid. If it is not if will request the data from the server who
5033 owns the client. Added new function
5034 silc_server_command_identify_check.
5036 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5037 to set the command to already allocated Command Payload.
5039 * Tested private message sending in router environment with two
5040 routers, two servers and two clients. Fixed minor bugs and now
5043 * Fixed segfault from client's NAMES command. Used to crash if
5046 * Forwarded packets must not be routed even if it is not destined
5047 to the receiver. Changed server code comply with this.
5049 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Added `require_reverse_mapping' boolean value to ServerParams
5052 structure. If TRUE (not default) the server will require that
5053 the connecting host has fully qualified domain name.
5055 If the reverse mapping is not required and hostname could not be
5056 found the IP address is used as hostname.
5058 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Implemented version string checking to both client and server.
5061 The check is incomplete currently due to the abnormal version
5062 strings used in development version of SILC.
5064 * Changed all command functions in server to use the new
5067 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Changed char *data to unsigned char *data in ID Cache system to
5070 support binary data as ID Cache data. Changed code to support
5071 binary data in lib/silccore/idcache.c.
5073 * Renamed silc_server_packet_relay_command_reply to
5074 silc_server_command_reply as it is normal packet receiving
5075 function. Rewrote the function to accept command replys for
5076 servers and not only for clients.
5078 * Mark remote router always as registered server if we are connecting
5079 to it. Otherwise, commands sent by the router to us are ignored.
5081 * All ID List find routines now returns the ID Cache Entry pointer
5082 as well if requested.
5084 * WHOIS command works now in router environment, tested with two
5085 routers, two servers and two clients.
5087 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5088 in router environment (as it is almost equivalent to WHOIS) but
5089 hasn't been tested thoroughly. Added new functions:
5091 silc_server_command_identify_parse
5092 silc_server_command_identify_send_reply
5093 silc_server_command_identify_from_client
5094 silc_server_command_identify_from_server
5096 * Disabled route cache adding because adding two different ID's with
5097 same IP replaces the old cache entry thus giving wrong route.
5098 The entry->router->connection is always the fastest route anyway
5099 so route cache may not be needed. Of course, new routes maybe
5100 established after receiving the ID when the entry->router->connection
5101 might not be anymore the most optimal.
5103 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Add route cache for received ID for fast routing.
5107 * Added silc_server_packet_route to route received packet on router
5108 that is not destined to us.
5110 * Renamed silc_server_get_route to silc_server_route_get.
5112 * Added id_string and id_string_len fields into SilcServer to
5113 include encoded ServerID for fast comparing without excess
5114 encoding of the ID's.
5116 * Cleaned up WHOIS command on server side. Added following static
5119 silc_server_command_whois_parse
5120 silc_server_command_whois_check
5121 silc_server_command_whois_send_reply
5122 silc_server_command_whois_from_client
5123 silc_server_command_whois_from_server
5125 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5126 arguments in command replies. All command functions should be
5127 updated to use this macro.
5129 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Minor typo fixes on command reply handling on server.
5133 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added silc_server_command_add_to_channel internal routine to add
5136 the client to the channel after router has created the channel and
5137 sent command reply to the server.
5139 * Added generic silc_server_send_command to send any command from
5142 * Use static buffer with ID rendering instead of duplicating data.
5144 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Fixed a channel user mode bug when joining to a channel server gave
5147 everybody channel founder rights, oops.
5149 * We mark ourselves as the router of the incoming server connection
5150 if we are router ourselves. This way we can check in some packet
5151 sending functions whether it is locally connected server. For
5152 incoming router connections we put NULL.
5154 * For router sending packets locally means now always sending the
5155 packet cell wide; to local clients and local servers. For normal
5156 server sending packet locally means sending it to only local
5159 * Fixed the JOIN command to really work in router environment. If the
5160 channel is created it is always created by the router. Router is
5161 also responsible of making the initial joining to the channel,
5162 sending JOIN notify to the sending server and distributing
5163 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5164 does not exist server doesn't do anything else but forward the
5165 command to the router which performs everything.
5167 * Added silc_server_send_channel_key function to send the Channel Key
5170 * Added silc_server_create_channel_key to create new channel key. The
5171 channel key is now re-generated everytime someone joins or leaves
5172 a channel, as protocol dictates. Note: channel->key_len is the
5175 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5178 packet_receive.[ch] to separate packet sending and receiving
5179 routines. The server.[ch] now includes everything else including
5180 actual packet processing (writing and reading data) and other
5183 Renamed silc_server_private_message_send_internal to
5184 silc_server_send_private_message. The routine is still though
5185 used only to relay private messages as server does not send
5186 private messages itself.
5188 Renamed silc_server_new_channel to silc_server_create_new_channel
5189 and added new function sicl_server_new_channel that handles the
5190 incoming New Channel packet. Added also new sending function
5191 silc_server_send_new_channel to send New Channel Payload.
5193 * Added new function silc_server_notify to process incoming notify
5194 packet to the server/router. Server may then relay the notify
5195 to clients if needed.
5197 * Added new function silc_server_new_channel_user to process incoming
5198 New Channel User packet. Router will redistribute the packet and
5199 send JOIN notify to its local clients and locally connected servers
5200 if needed. Normal server will send JOIN notify to its local client
5201 on same channel when received this packet. Added also corresponding
5202 sending function silc_server_send_new_channel_user to sent the
5205 * Added boolean route argument to send_notif_to_channel and
5206 packet_send_to_channel functions to attempt to route the packet
5207 if it is TRUE and send only locally if it is FALSE.
5209 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * silc_server_replace_id now broadcasts the received replace ID
5212 packet if it is not broadcast packet already. The router must
5213 broadcast to inform other routers about changed ID.
5215 * Added backpointer to server's router into SilcServer context in
5216 silcd/server_internal.h.
5218 * Fixed silc_server_packet_broadcast to send correct broadcast
5221 * The channel key is now distributed to the local client as soon
5222 as it is received from the router (in router environment) so that
5223 no other packet may be sent for the channel until client has
5226 * silc_server_remove_channel_user now broadcasts the received
5227 Remove Channel User packet if it is not broadcast packet already.
5228 The router must broadcast to inform other routers about removed
5231 * Added users field into SilcPacketContext that is a reference count
5232 of the context. One can increase the reference count by calling
5233 silc_packet_context_dup which is now changed to just increase the
5234 reference count instead of duplicating the data. The reference
5235 count is decresed by calling silc_packet_context_free that will
5236 free the data after the reference count hits zero.
5238 For now on the packet context and everything allocated into it
5239 (including the raw packet from network) must be freed by calling
5240 the new silc_packet_context_free function. Added also new function
5241 silc_packet_context_alloc that must be used now to allocate the
5242 context. This also means that if a routine is asynchronous from
5243 silc_[client/server]_packet_parse_type the packet context must
5244 be duplicated by calling silc_packet_context_dup. Otherwise it
5245 gets free'd after silc_[client/server]_packet_parse_type returns.
5246 Also, one must remember that if packet is duplicated then its
5247 reference count must be decresed by calling the free function as
5248 many times as it was duplicated.
5250 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5251 from both client and server.
5253 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Made joining to a channel working in router environment.
5257 * Cleaned up JOIN command on server side and create function
5258 silc_server_command_join_channel internal routine to make the
5261 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5263 * Changed silc_command_pending list to SilcDList. Also, added
5264 `ident' field to SilcServerCommandPending structure to identify
5265 the reply and to call correct callback.
5267 Added silc_server_command_pending_check function to replace the
5268 corresnponding macro. The silc_command_pending list is not
5271 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5272 to set identifier to previously allocated Command Payload. It
5273 is used to set identifier for command when resending Command
5276 * Added silc_command_payload_encode_payload to encode Command
5277 Payload buffer from SilcCommandPayload structure.
5279 * Added silc_argument_payload_encode_payload to encode Argument
5280 payload buffer from SilcArgumentPayload structure.
5282 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Changed WHOIS command to support router connection on server side.
5285 The whois request is always sent to router unless the server is
5286 standalone server. After server has received the reply from the
5287 router will it send the reply to the client.
5289 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5290 broadcast received broadcast packet. The function is used only
5291 by router. The broadcast packet is always sent to the router's
5294 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5295 render given ID to printable string, for log files for example.
5297 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Made basic router to router connections working. At least they
5300 can now connect to each other but nothing really works the way
5301 they are supposed - yet.
5303 * Added new initiator token to RouterConnection configuration
5304 file in silcd/serverconfig.[ch]. It is used to tell whether we
5305 are the initiator to the remote router or whether we'll expect
5306 the other end to connect.
5308 * Moved registering of listener task to silc_server_init, hence
5309 the server starts listenning as soon as it is run, even if it
5310 does not have connections to other routers. Let's see how well
5313 * Changed default connection retry timeouts for more suitable in
5316 * Removed cipher and such arguments from silc_idlist_add_client
5317 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5318 Added new function silc_idlist_add_data to add the keys and stuff
5321 * Added SilcIDListData structure and added it to SilcClientEntry
5322 and SilcServerEntry as their first field in the structure. This
5323 way we can explicitly cast the ID entries to the SilcIDListData
5324 structure and get common data for the entries. In past, we had
5325 to first check what type of connection it is and then cast it to
5326 correct ID entry type. Now, we can directly cast the opaque
5327 pointer to the SilcIDListData (no matter what ID entry it actually
5328 is) and get the data needed.
5330 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5333 in some circumstances even if threre were timeout tasks, though not
5334 IO tasks, but tasks anyway. Now fixed.
5336 * Defined SilcServerConnection structure to hold connection specific
5337 stuff about directly connected servers and routers. The definition
5338 is currently in silcd/server_internal.h. I thought about having
5339 a bit more important role fro this struct but for now it is used
5340 only when connecting to other server (or router actually).
5342 * Added connecting retry support in server when connecting to
5343 router(s). The retry feature implement exponential backoff
5344 algorithm. Also, added SilcServerParams structure to hold default
5345 parameters for server. For now, it include these retry settings
5346 and are hard coded. After server is moded to be as Silc Server
5347 Library this structure will be more important.
5349 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Changed client librarys channel->clients table to SilcList and
5352 changed code accordingly.
5354 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * Changed client's channel table to SilcList and changed code
5357 accordingly. Also changed SilcChannelClientEntry to include back-
5358 pointer to the channel so that client entry can use that structure
5359 as list as well and we have fast cross-reference to the channel.
5360 This change dramatically decreased the complexity of channel
5361 handling with client entry and vice versa (removed one extra
5362 loop when searching for channel entry from many functions).
5364 * Changed server->sim from table to SilcDList and changed code
5367 * NAMES command can now be used from user interface. It will show
5368 the user list on the channel, neatly.
5370 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5371 Code now saves realname of the user if it becomes available.
5373 * Renamed configure.in to configure.in.pre and made ./prepare
5374 script to automatically add correct version string to
5375 configure.in which it creates from configure.in.pre.
5377 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * NAMES command reply now shows users mode with the nickname when
5382 * Moved silc_client_ch[u]mode[_char] functions from
5383 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5384 place sucks, they are utility functions and should be in some
5387 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5389 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5392 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added TRQ (efficient deque and list library) into lib/trq. This is
5397 a very good list library that is currently used in the SILC. Defined
5398 SilcList API over the library because I didn't like the API very
5399 much. See lib/trq/silclist.h for the API and examples of how to
5400 use the API. Fixed various places in the code to use the new
5401 SilcList API. The SilcList is meant for lists that has a structure
5402 already defined as a list. It is not suitable to add just some
5403 context to the list (in TRQ, the context is the list actually).
5405 So, I defined SilcDList that can be used for the purpose where
5406 predefined list structure does not exit. This can be used as
5407 such list. Now some context just can be added to the SilcDList.
5408 Currently this list is not used in the SILC just yet, though there
5409 are a lot places where this can replace dynamically allocated
5410 tables and I will fix these places, later, to use SilcDList.
5411 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5412 and use TRQ internally).
5414 Also fixed some annoying warning messages that the original TRQ
5415 code generated. Also minor changes to TRQ's Makefile.in.
5417 * Added support for querying by Client ID to both WHOIS and
5418 IDENTIFY commands into server, as required by the protocol.
5420 * Removed method function pointers from SilcBuffer structure. They
5421 weren't used to anything and just increased the context size for
5422 no good reason. This change also made silc_buffer_alloc and
5423 silc_buffer_free functions inline functions.
5425 * Disabled command flooding detection support until it's fixed so
5426 that it accepts commands in but does not execute them more than once
5429 * Added silc_net_localhost(), to return local hostname, into
5430 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5431 that must be initialized before calling silc_client_init.
5433 * Added new function: silc_server_send_notify_on_channels to send
5434 notify messages to all channels client has joined. It is assured
5435 that the message is sent only once per client.
5437 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5438 lib/silcutil/silcutil.[ch] as silc_format function. The new
5439 function is generic and is used by server as well, not only by
5440 the logging routines.
5442 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5443 the provided version string was not acceptable. Added new function:
5444 silc_ske_check_version into lib/silcske/silcske.h. The function
5445 must be implemented by the application (client or server) and it
5446 does not reside in the SKE library. The function checks the version
5447 string remote end sent.
5449 * Added back pointers (to opaque context and to SilcSocketConnection)
5450 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5452 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5453 duplicate packet context structure.
5455 * Changed `notify' client operation to send same arguments as client
5456 receives from server except for ID's. ID's are mapped to correct
5457 ID entry and that is returned. Also, if channel entry is not sent
5458 by server but the notify is for channel the channel entry is sent
5459 to application (otherwise application doesn't know that it is for
5460 channel (library gets it from packet's Destination ID)).
5462 * Added silc_client_remove_from_channels into client library to
5463 remove a client from all channels it has joined to. Used when
5464 received SIGNOFF notify from server. Added also new function
5465 silc_client_replace_from_channels to replace old ID entry with
5466 new ID entry on all channels. Used when received NICK_CHANGE
5469 * Fixed ID Cache list handling in silc_idlist_get_client in
5470 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5471 to get (or query) client by ID.
5473 * Updated TODO list.
5475 * Added connection authentication status message defined by the
5476 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5477 support for these into the code in client and server side.
5479 * Added generic function silc_client_send_command to send any command
5480 with variable argument list. Application should use this function
5481 to send commands if the command functions provided by the library
5482 does not suite for the application's user interface needs.
5484 * Added new `failure' client operation. Application is notified about
5485 received failure packet if client is executing a protocol. In this
5486 case the protocol's execution has failed.
5488 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5489 is required by the protocol.
5491 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5492 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5495 * Added status flag to SilcSKE object to indicate realtime status
5496 of the SKE protocol.
5498 * Application receives now exactly same command reply arguments as
5499 the library receives from server. However, if ID is received the
5500 corresponding ID entry is returned to the application (eg. Client
5501 ID is mapped to correct SilcClientEntry entry and that is returned).
5502 Changed command_reply client operation due to this change.
5504 * Changed all ID's in commands and in command replys as ID Payloads.
5505 Change affected both client and server side codes.
5507 All ID's sent in SILC network (with execption of ID's in SILC
5508 Packet header) are sent in ID Payload to support variable length
5511 * Server now notifies nick changes and notifies all clients on
5512 the channels about the new nickname (about the new Client ID,
5515 * Implemented CMODE command to change channel modes. Supports all
5516 channel modes defined by the protocol specs except ban and invite
5517 lists. (Also, private channel key mode is supported but support for
5518 setting private channel key in client is missing, thus, this mode
5519 has no effect on client side (except that server requires that the
5520 client uses private channel key and normal channel traffic does not
5523 Also, invite mode works per se, but INVITE command does not work
5524 yet correctly, so you can set channel as invite only channel but
5525 inviting clients to the channel does not work (it is yet to be
5526 thought what's the best way to do it).
5528 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5529 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5530 Implemented CUMODE command to change user's mode on the channel.
5531 Supports all modes defined by the protocol specs.
5533 * Added NAMES command reply to return users modes on the channel.
5535 * Removed unnecessary and slow ciphers from lib/silccrypt.
5537 * Set SO_KEEPALIVE option to connection sockets by default.
5539 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5541 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5542 redefined the Notify Payload into protocol specs.
5544 * Added silc_id_payload_parse_id to get ID directly from raw
5547 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5550 accept searching by Client ID as well.
5552 * Added support for LEAVE and SIGNOFF notify types in client library.
5554 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5555 to parse ID Payload from raw data.
5557 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Added flags parameter into silc_ske_assemble_security_properties
5560 function in lib/silcske/silcske.[ch].
5562 * Changed notify client operation to fit better for notify messages
5563 sent by server. The notify payload received from server is now
5564 passed to the application (after parsing it to SilcNotifyPayload).
5565 It is application's responsibility to retrieve the arguments
5566 from the payload and show the message the way it wants. The message
5567 sent by server is implementation specific.
5569 * Changed public keys to comply with the protocol specification.
5570 Old public keys are not supported anymore and are not compatible.
5572 * Removed nickname from Channel Payload as the latest draft removed
5573 it. The client must resolve the nickname from the NAMES command
5574 reply received when it joined the channel.
5576 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5578 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Fixed some errors in protocol specification drafts.
5582 * Created lib/silccore/silcnotify.c to implement Notify Payload
5583 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5584 generic payloads described by protocol specifications. The file
5585 includes implementations for ID Payload and Argument Payload.
5587 * Changed Command Payload implementation to use the new Argument
5588 Payload. Changed command_xxxx_payload to command_payload_xxxx
5589 to comply with SILC coding conventions.
5591 * Added suppport for Argument Payload handling in Notify Payload
5592 implementation as protocol requires it. Added the new support
5593 into server and client lib as well.
5595 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added support for multiple nicknames on same channel. [n] is
5598 added locally to the nickname if there are more than one same
5599 nicknames on the channel.
5601 * Server now sends all nicknames that matched WHOIS request.
5602 Client also shows the list received from server.
5604 * Added TOPIC command to client side. User can now set and show
5605 current topic on channel.
5607 * Added MOTD command to client and server. Also, server sends the
5608 motd when client connects to the server.
5610 * Changed version strings to comply ISO 8601.
5612 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Fixed protocol error handling in client library. It should now
5615 cope even if the SKE fails for some reason.
5617 * Made new protocol specification drafts for submitting to IETF.
5619 * Implemented TOPIC command to server in silcd/command.c.
5621 * Added two new notify types into lib/silccore/silcnotify.h:
5622 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5623 notify nickname change and topic setting/change on a channel.
5625 * API change of command_reply operation in client library. The
5626 application gets now the status type received from server as well.
5628 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5632 * Cras fixed and optimized the packet handling even further and
5633 it should work now. Minor change to the prototype of function
5634 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5636 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Added new function into lib/silcutil/silcschedule.[ch]:
5639 silc_schedule_with_fd to select() a specified fd. The function
5640 returns after timeout expires or data arrives or goes. The
5641 function is used by packet routines to wait that all data is
5642 received from network.
5644 * Fixed data reading from network in lib/silccore/silcpacket.c.
5645 The code now assures that all data is read from the fd and then
5646 continues packet processing. This was a bug fix since the code
5647 used to drop some data in some circumstances.
5649 * Added new function into lib/silcclient/client.[ch]:
5650 silc_client_start_key_exchange to start key exchange after
5651 connection has been established to server. The code internally
5652 now uses this funtion but its main purpose was to provide it
5653 for applications that perform their own connecting. After
5654 application has created a connection it merely calls this
5655 function to start the key exchange between client and server.
5656 The library takes care of everything else after that.
5658 Updated also lib/silcclient/README to explain the usage of
5661 * Do not send to application information that connection has
5662 been established. Application gets notified it by connect
5665 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Applied cras's patch to add silc_schedule_one function. The
5668 function runs scheduler once and returns.
5670 * Fixed the scheduler after cras messed it up. The timeout
5671 handling works now as it's supposed to work.
5673 * Added into lib/silccore/ silcnotify.h to include notify
5674 message types support. Changed silc_server_send_notify*
5675 functions, in server.[ch], to support those new notify types.
5676 Added the support for the notify types into client library,
5677 as well. Added new notify client operation into ops.h in
5680 * Changed silc_server_packet_send_to_channel to send normal
5681 packets instead of just channel message packets. The function
5682 is now used to send the notify packets to channels. It is not
5683 used to send channel message packets anymore, as server never
5686 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5687 va_arg()s as it seems to require it nowadays. I guess, if SILC
5688 is compiled with older va_arg() the new code should work anyway.
5690 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Splitted core library. Core library (lib/silccore) includes
5693 now only SILC protocol specific core (and common) components.
5694 Created new utility library (lib/silcutil) that includes more
5695 generic purpose stuff. The stuff for util library was taken
5696 from the old core library. This was minor and easy split.
5698 * Created SILC Client Library (lib/silcclient) that includes
5699 implementation of the SILC client without user interface. This
5700 was major move from silc/ directory. The code has been changed
5701 so that it is transparent towards the user interface. The
5702 silc/ directory includes now the same user interface as before
5703 and it uses the new client library. Read lib/silcclient/README.
5704 Basicly, the client library performs everything else related
5705 to SILC except user interface handling. Also, configuration
5706 files are considered to be part of user interface and library
5707 does not handle them.
5709 This change also changed a lot of structures, function naming etc.
5710 Most important change was that SilcClientWindow object was
5711 renamed to SilcClientConnection in the client library. Created
5712 also new file lib/silcclient/ops.h. Also added new files
5713 silc/local_command.[ch] and silc/client_ops.[ch].
5715 All these changes were made to make it easier for user interface
5716 designers to create what ever user interface for the SILC client
5719 It is also expected that the server will be moved to lib
5720 directory as well and SILC Server Library will be created;
5721 sometimes in the future.
5723 * Removed Local commands from lib/silccore/silccommand.h as
5724 they are application specific and new client library does not
5725 handle any of those anymore.
5727 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5728 old client implementation in silc/.
5730 * Added support for callback functions in SILC_LOG_* macros.
5731 Application can now set its own callbacks that will be called
5732 instead of using the default functions that will always print
5733 the debug messages to stderr (or stdout). Also, debugging can
5734 now be disabled by setting silc_debug to FALSE and re-enabled by
5735 setting it to TRUE. Note, that logging will still work even
5736 if debugging is disabled.
5738 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5739 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5740 silc_log_reset_debug_callbacks.
5742 * To enable debugging in silc client one must give now -d
5743 option on command line.
5745 * Changed silc_schedule_init to automatically allocate task queues
5746 if they are not allocated before calling it.
5748 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Added GMP 3.1 into math library.
5752 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5755 a channel in SILC network. The packet is used by servers and
5756 routers to notify other routers that user has left a channel.
5757 This little feature was missing until now. Added the feature
5758 to protocol specification as well.
5760 Added functions: silc_server_send_remove_channel_user and
5761 silc_server_remove_channel_user into server.[ch].
5763 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5764 lib/silccore/silcpacket.h. However, they are not implemented
5767 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Fixed joining to a channel and sending channel messages
5770 between server and router. The channel message sending should
5771 now work inside a cell.
5773 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Fixed the private message sending between server and router.
5776 The private message sending should now work inside a cell.
5778 * Added silc_server_replace_id into server.[ch] to replace
5779 existing ID in the SILC network.
5781 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5782 and silc_idlist_replace_server_id into idlist.[ch] in server.
5784 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Fixed the server to server connections. Server can again now
5787 connect to router. Router to router connections probably does
5790 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added dynamic protocol registering support. Now protocols can
5793 registered and unregistered on the fly. Patch by cras.
5795 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added lib/contrib directory to hold routines that some platforms
5798 don't have but are needed by SILC.
5800 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5801 into lin/contrib to provide getopt() and getopt_long() for
5802 those who don't have it.
5804 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Added AWAY command to client. When away message is set and
5807 client receives a private message packet the client automatically
5808 replies to the sender with the away message.
5810 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5811 bug seemed to be the cause of recent problems when compiling
5814 * Added version detection support to SKE protocol specification
5815 and added the new changes to the SKE implementation as well.
5816 There were other minor changes in the SKE protocol as well.
5818 Many changes in lib/silcske/silcske.[ch] and in
5819 lib/silcske/payload.[ch].
5821 * Added ^U functionality, clear input line. Patch from cras.
5823 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Mainly small bugfixes on core library. Fixed some debugging
5826 logging and buffer overflow in silclog.c.
5828 * Updated config.sub and config.guess on the distribution tree.
5830 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Added command lagging support in server. Client may execute
5833 commands now only once in two seconds.
5835 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Optimized packet reception. MAC computation and checking is now
5838 also more optimized. A lot previously duplicated code is now
5839 used as generic by both client and server.
5841 * Fixed key pair generation in clientutil.c
5843 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added into lib/silccore/silcbufutil.[ch] new function;
5846 silc_buffer_realloc.
5848 * Moved generic packet sending/encryption functions to
5849 lib/silccore/silcpacket.[ch] from client and server. Some
5850 rewriting of the functions.
5852 * Moved all generic packet reception/decryption functions to
5853 lib/silccore/silcpacket.[ch] from client and server. The
5854 packet processing is now much cleaner in both client and server.
5855 These were major changes in both client and server.
5857 * Created many common functions in server to do packet sending.
5858 Previously code were duplicated a lot, this has been removed
5861 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Rewrote major parts of the ID cache system. Don't know
5864 whether it is better now or not but at least the API is more
5867 * Major rewrite on ID cache stuff on client because of the ID
5868 cache API changes. Added idlist.c to client.
5870 * Also major rewrite on ID cache stuff on server as well.
5871 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5872 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5873 in hand, instead they are all put into the ID cache system now.
5874 All server_idlist_* routines uses ID cache now instead of
5875 traversing its own lists (those lists does not exist anymore).
5876 SilcIDList though still exists. Also, SilcXXXEntry's are
5879 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Finally made the SKE implementation compliant to the protocol
5882 specification. All mp integers are now binary encoded as
5883 opposed being HEX encoded.
5885 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5888 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5889 functions: silc_[encode/decode]_pem. Also added function
5890 silc_encode_pem_file to PEM encode with newlines ('\n') for
5893 * SILC public keys are now encoded either PEM or binary. Same
5894 option is for private keys as well. By default private keys
5895 are binary encoded and public keys PEM encoded. Silly HEX
5896 encoding were removed.
5898 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5899 function to create fingerprints.
5901 * Fixed a bug in SHA1; does not change the original data anymore.
5903 * Partly implemented INFO command on client and server side.
5904 Fixed CLEAR command. Changes to SERVER command; show current
5905 server(s) when giving command without arguments. Added
5906 VERSION command to client.
5908 * Added check to server that unregistered connections cannot
5909 execute commands (unless it is specificly allowed).
5911 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Fixed screen refresh.
5915 * Fixed channel joining bug from client. On some circumstances
5916 client tried to join to a channel it had already joined.
5918 * Added public key verification process into client's protocol.c.
5919 The client now verifies the public key from user and saves
5920 it into ~./silc/serverkeys/ directory.
5922 Added into: clientutil.[ch]: silc_client_verify_server_key.
5924 * Changed SKE protocol's silc_ske_initiator_finish function
5925 to accept callback function that verifies the received public
5926 key. Removed old silc_ske_verify_public_key function.
5928 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5931 silc_pkcs_private_key[_data]_set.
5933 * Made the password and public authentication more cleaner in
5934 server's protocol.c.
5936 * Removed historic and obsolete protocol `channel_auth' from
5937 both client and server.
5939 * Removed wrong way of sending command status messages from
5940 server to client in server's command.c. The old way violated
5941 protocol specification.
5943 Changes to silccore/silccommand.[ch]: removed
5944 silc_command_encode_status_payload -> not needed anymore,
5945 changed silc_command_encode_payload_va to accept extra
5946 argument on variable argument list. The argument type must
5947 now be provided to the function. Also, added new function:
5948 silc_command_encode_reply_payload_va which is same as
5949 normal command_encode_payload_va except command status type
5950 is provided as extra argument.
5952 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
