1 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Renamed silc_file_read and silc_file_write to functions
4 silc_file_readfile and silc_file_writefile. Added function
5 silc_file_open and silc_file_close. Affected files
6 lib/silcutil/silcutil.[ch].
8 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Resolve the client info when received private message or
11 channel message for a client which nickname we don't know.
12 Affected files lib/silcclient/client_prvmsg.c and
13 lib/silcclient/client_channel.c.
15 * Do not crash in /KEY if client is not connected. Affected
16 file irssi/src/silc/core/silc-channels.c.
18 * Added SilcClientStatus field to the SilcClientEntry in the
19 lib/silcclient/idlist.h.
21 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
22 is incomplete and is being resolved, it won't be resolved
25 Make sure also that USERS command reply does not resolve
26 twice information. Affected file is
27 lib/silcclient/command_reply.c.
29 Make sure that silc_client_get_clients_by_list does not
30 resolve twice same information.
32 * Check for valid client->id in the silc_server_free_client_data.
33 Affected file silcd/server.c.
35 * Fixed /GETKEY nick@server not to crash if the server entry
36 is not found. Affected file lib/silcclient/command.c.

39 requested modes correctly. Affected file silcd/command.c.
41 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Better checks for non-printable chars in nick added.
44 Affected file silcd/command.c.
46 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
48 * Call the silc_server_udpate_servers_by_server in the
49 primary router that comes back online in the backup resuming
50 protocol. Otherwise it routes packets wrong. Affected file
51 silcd/server_util.[ch], silcd/server_backup.c.
53 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
55 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
56 lib/silcutil/silcbuffmt.[ch].
58 * Redefined the SILC packet header to include the padding
59 length. Affected file lib/silccore/silcpacket.[ch].
61 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
62 length for maximum padding up to 128 bytes). Affected
63 file lib/silccore/silcpacket.h.
65 * Removed all backwards support for old 0.5.x MAC thingies.
66 The SILC packet header change makes it impossible to be
69 * Send the ENDING packet with timeout in the backup resuming
70 protocol. This is to assure that all routers has connected
71 to the primary router. Affected file silcd/server_backup.c.
73 * Changed the RNG to take the first IV from random data. It
74 used to take it from zero actually. Changed the RNG also
75 to use /dev/urandom during session. /dev/random is used
76 in initialization. Affected file lib/silccrypt/silcrng.[ch].
78 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
80 * Changed the SILC packet header to have the first two bytes
81 (the packet length) encrypted. Affected files aroung the
82 code tree, lib/silccore/silcpacket.[ch]. Removed the
83 SilcPacketCheckDecrypt callback. It is not needed anymore
84 since the silc_packet_receive_process will determine now
85 whether the packet is normal or special.
87 * Implemented the unidirectional MAC keys. Affected files
88 lib/silcske/silcske.c, silcd/protocol.c and
89 lib/silcclient/protocol.c.
91 * Implemented the packet sequence number to the MAC computation.
92 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
93 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
94 lib/silcclient/protocol.c.
96 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
98 * Allow backup router to announce servers. All servers
99 announced by backup router are added to the global list
100 automatically. Update hte server's socket to our primary
101 router also when backup router announces a server.
102 Affected file silcd/packet_receive.c.
104 * Do not update the client->router in the function
105 silc_server_udpate_clients_by_server if the client is on
106 global list. We might fail to find any specific server
107 for locally connected clients and local cell clients. They
108 should still use the `from' and not `to' as client->router.
109 This fixes backup router resuming protocol. Affected file
112 * Decrease channel statistics count only if the channel
113 deletion worked. Affected files are silcd/server.c and
116 * Added silc_server_update_servers_by_server to update origin
117 of all server entries. Used during backup router protocol.
118 Affected files silcd/server_util.[ch], silcd/server.c. and
119 silcd/backup_router.c.
121 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
122 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
123 silc_hmac_get_hash and silc_hmac_get_name. Affected file
124 lib/silccrypt/silchmac.c.
126 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
128 * Assure that router cannot reroute the same channel message
129 to the sender. Affected file silcd/packet_receive.c.
131 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
133 * Made better checks that the channel message is not sent
134 to the router it came from. Affected file is
135 silcd/packet_send.c. Fixed memory leak too.
137 * Announce informations for incoming router connection, but
138 only after checking if it is replaced by backup router.
139 Affected file silcd/packet_receive.c.
141 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Fixed the backup resuming protocol to work in multiple
144 router environment. Affected file silcd/server_backup.c.
146 * Route packet only to one router in the function
147 silc_server_packet_send_to_channel. Affected file is
150 * Fixed silc_server_send_notify_dest to set the broadcast
151 flag. Fixed the silc_server_send_notify_topic to actually
152 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
153 Affected file silcd/packet_send.c.
155 * Changed the SFTP Filesystem interface. Changed the
156 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
157 the filesystem operation function. The SilcSFTPFilesystem
158 is now a context that is allocated by all filesystem allocation
159 functions and it already includes the operations structure
160 and filesystem specific context. It is given as argument
161 now to the silc_sftp_server_start. This made the interface
162 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
163 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
165 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
167 * Changed the backup router adding and getting interfaces
168 in the server. The router that will be replaced by the
169 specified backup router is now sent as argument. Affected
170 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
173 * Added silc_net_addr2bin_ne to return the binary form of
174 the IP address in network byte order. Affected files
175 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
177 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Check for existing server ID in silc_server_new_server
180 and in silc_server_connect_to_router_final and remove the
181 old entry if it exists. Affected file silcd/packet_receive.c,
184 * Send the channel message always to only one router, either
185 in upstream or downstream. Affected file is
188 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Wrote the definition of the backup resuming protocol to the
191 protocol specification.
193 * Removed one redundant channel key generation from normal
194 server during joining procedure. Removed one redundant
195 channel key sending from server to router during joining
196 procedure. Affected file silcd/command.c.
198 * Made minor bugfixes to the backup router resuming protocol.
199 Affected file silcd/server_backup.c, server.c.
201 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
203 * Added --disable-asm configuration option. Affected files
204 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
207 * Implemented the backup resuming protocol that is used to
208 resume the primary router position in the cell after the
209 primary router comes back online. Affected files
210 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
211 and silcd/server_util.[ch].
213 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
215 * Sleep two (2) seconds after sending QUIT command to server.
216 Affected file lib/silcclient/command.c.
218 * Assure that if outgoing data buffer is pending do not force
219 send any data. Affected file silcd/packet_send.c.
221 * Assure that if outgoing data buffer is pending do not force
222 send any data. Affected file lib/silcclient/client.c.
224 * Implemented the backup router support when the primary router
225 goes down. The servers and routers can now use the backup
226 router as new primary router without loosing connectivity.
228 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
230 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
231 in the server to indicate disabled entry. All data read
232 from the connection will be ignored and no data is sent
233 for entry that is disabled. Affected files are
234 silcd/idlist.h, silcd/server.c.
236 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
238 * Created SFTP client and server test programs in the
239 lib/silcsftp/tests directory.
241 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Implemented memory filesystem (virtual filesystem) for
244 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
247 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
249 * Implemented the SFTP (SSH File Transfer Protocol) to the
250 lib/silcsftp. It includes SFTP client and SFTP server
253 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
255 * Moved lib/silccore/silcprotocol.[ch] to the
256 lib/silcutil library.
258 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
259 take variable argument list pointer as argument. Affected
260 file lib/silcutil/silcbuffmt.[ch].
262 * Added silc_buffer_set function that is used to set data
263 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
264 Affected file lib/silcutil/silcbuffer.h.
266 * Changed various routines in the core library to use the new
267 silc_buffer_set instead of allocating new buffer only for
270 * Added 64-bit value formatting and unformatting support to the
271 silc_buffer_[un]format routines. Affected file is
272 lib/silcutil/silcbuffmt.[ch].
274 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
275 to includes/bitmove.h.
277 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
279 * Fixed channel user mode saving in client library. Affected
280 file lib/silcclient/command[_reply].c.
282 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
284 * Defined the file transfer to the SILC Protocol. Added
285 new packet type SILC_PACKET_FTP and defined File Transfer
286 Payload. The mandatory file transfer protocol is SFTP
287 (SSH File Transfer Protocol). Affected file in addition
288 of the internet draft is lib/silccore/silcpacket.h.
290 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
291 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
292 is used as part of backup router protocol when the primary
293 router of the cell is back online and wishes to resume
294 the position as primary router.
296 * Redefined the MAC generation keys in the protocol. The
297 same key is not used anymore in both direction. Both
298 direction will now use different keys for sending and
299 receiving. This fixes a potential security flaw. This
300 change causes incompatibilities in the protocol.
302 * Redefined also the MAC computation from the packet.
303 An packet sequence number is now added to the MAC
304 computation. This prevents possible replay attacks against
305 the protocol. This change too causes incompatibilities
308 Added `sequence' field to the SilcPacketContext to hold
309 the current sequence number for the packet.
311 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
313 * Added `created' field to the SilcIDListData in the file
314 silcd/idlist.h to indicate the time when the entry was
317 * Added `created' field to the SilcChannelEntry too. Affected
320 * Added `creation_time' aguments to all the announcement functions
321 in the server. If it is provided then only the entries that
322 was created after the provided time frame are actually
323 announced. Affected file silcd/server.[ch].
325 * The protocol says that the Channel ID's IP address must be
326 based on the router's IP address. Added check for this in
327 the silc_server_new_channel when processing incoming New Channel
328 Payload. Affected file silcd/packet_receive.c.
330 * Print out the correct version with --version in SILC client.
331 Affected file irssi/src/silc/core/silc-core.c.
333 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
335 * Fixed WHOWAS command to check for completnes of the client
336 entry always, not just when the command is coming from client.
337 Affected file silcd/command.c.
339 * Added new function silc_server_packet_queue_purge to purge the
340 outgoing data queue to the network. After the function returns
341 it is guaranteed that the outgoing packet queue is empty.
342 Affected file silcd/packet_send.[ch].
344 * Purge the outgoing packet queue in the rekey protocol's final
345 callback to assure that all rekey packets go to the network
346 before quitting the protocol. Affected file silcd/server.c.
348 * Added silc_client_packet_queue_parse as similar function as
349 in server to the client library. The affected file is
350 lib/silcclient/client.c.
352 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
354 * Splitted silcd/server.c and created silcd/server_util.[ch]
355 for utility functions.
357 * Added new socket flag SILC_SF_DISABLED to indicate that the
358 connection is open but nothing can be sent to or received from
359 the connection. Affected file lib/silcutil/silsockconn.[ch].
360 The checking for disabled socket is checked in the low level
361 silc_socket_write and silc_socket_read functions.
363 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
365 * Allow only nicknames and channel names that fits into the
366 7-bit unsigned char ASCII set. Affected file silcd/command.c.
368 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
370 * When processing JOIN command reply in server check that if
371 the channel exists in our global list we'll move it the local
372 list. Affected file silcd/command_reply.c.
374 * Fixed the check whether client is joined on the channel already
375 in JOIN command. Affected file lib/silcclient/command.c.
377 * Fixed the JOIN command reply to check whether the channel
378 already exists. Affected file lib/silcclient/command_reply.c.
380 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
382 * Added silc_ske_status_string to map the SKE error numbers
383 to readable strings. The affected files are
384 lib/silcske/silcske[_status].[ch].
386 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Do not show the private channels on the WHOIS channel list
389 as it is not allowed by the protocol. The affected file is
392 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
394 * Assure that the packet length digged from the actual packet
395 is something sensible in the silc_packet_decrypt_rest_special
396 in lib/silccrypt/silcpacket.c.
398 * Free and NULL the allocated pointer in silc_hmac_alloc if
399 the HMAC allocation fails. The affected file is
400 lib/silccrypt/silchmac.c.
402 * Print the selected security properties to the log files in
403 the server. Affected file silcd/protocol.c.
405 * Add SKE's reference counter even if calling the completion
406 callback manually. Otherwise it goes negative, although it
407 does not cause any problems. The affected file is
408 lib/silcske/silcske.c.
410 * Remove the client entry with short timeout after giving the
411 KILL command. Affected file lib/silcclient/command.c.
413 * Fixed to send error reply in WHOIS and IDENTIFY commands in
414 case all found clients are already disconnected (WHOWAS would
415 found them) in the server. Affected file silcd/command.c.
417 * Update the last_receive (time of last data received) to be
418 updated only when received private or channel message so that
419 the idle time showed in WHOIS makes more sense.
421 * Added boolean field `valid' in to the SilcClientEntry in the
422 client library to indicate whether the entry is valid or not.
423 This fixes the nickname change bug on channel when changing
424 the nickname to be same than the old (like nick to Nick) the
425 nickname formatter doesn't set the new nick anymore to Nick@host.
426 Affected file lib/silcclient/idlist.[ch].
428 * Now actually fixed the nickname changing on disconnection.
429 Added new function silc_change_nick to the Irssi SILC Client.
430 Affected file irssi/src/silc/core/client_ops.c,
431 irssi/src/silc/core/silc-nicklist.[ch].
433 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
435 * Check that the public key exists in the GETKEY command before
436 trying to encode it. Affected file silcd/command.c.
438 * Print some notifications on received public keys with GETKEY
439 command in the Irssi SILC Client. Affected files are
440 irssi/src/fe-common/silc/module-formats.[ch],
441 irssi/src/silc/core/client_ops.c.
443 * Use IDENTIFY command to resolve the server information in the
444 GETKEY command instead of INFO command. Affected file
445 lib/silcclient/command.c.
447 * All command reply functions in the client library now calls
448 the pending command reply callbacks even if an error has
449 occurred. The server has done this a long time and now it was
450 time to move the client library to this as well. Now all
451 errors can be delivered back to the pending command reply
452 callbacks if necessary. Affected files are
453 lib/silcclient/command[_reply].[ch].
455 * Change the nickname on disconnection back to the username
456 because in reconnect the server will enforce it to it anyway.
457 Affected file irssi/src/silc/core/silc-servers.c.
459 * Fixed a config file parsing bug in the Irssi SILC client.
460 Affected file irssi/src/silc/core/clientconfig.c.
462 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
464 * When printing the channel mode on JOIN, verify that the
465 channel key and channel's HMAC are valid. Affected file
466 irssi/src/silc/core/client_ops.c.
468 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
470 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
471 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
472 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
474 * Removed channel key rekey task deleting from the function
475 silc_server_save_channel_key. Affected file silcd/server.c.
476 Added explicit timeout task context instead that is used to
477 delete the task if we are registering a new task before the
478 new task has elapsed.
480 * When channel key rekey occurs the client library now saves
481 the old channel key for a short period of time (10 seconds) and
482 is able to use it in case some is still sending channel
483 messages encrypted with the old key after the rekey. Affected
484 file lib/silcclient/[idlist.h|client_channel.c].
486 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Added check to the silc_server_new_id_real to not accept
489 new ID if it is the sender's own ID. Affected file is
490 silcd/packet_receive.c.
492 * Assure that we do not announce ourself or the one we've
493 sending our announcements when we're router and are announcing
494 servers to our primary router. Affected file silcd/server.c.
496 * Fixed silc_server_command_identify_check_client to assemble
497 correct WHOIS packet. It send corrupted WHOIS packet and
498 caused problem with router to router connections. Affected
499 file silcd/command.c.
501 Fixed also silc_server_command_whois_check the same way
502 as for the IDENTIFY command.
504 * Added new SilcIDListStatus to the server in the SilcIDListData
505 structure. The status now includes the current status of
506 the entry (like registered, resolved etc.). Affected file
507 silcd/idlist.[ch]. Defined a bunch of different status types
508 as well. This replaced the old boolean registered field as well.
510 Added resolve_cmd_ident field to the SilcClientEntry structure
511 too so that if the entry is for example being resolved so
512 another command may attach to the same pending command reply
513 without requiring to resolve the same entry again. This concept
514 should optimize the WHOIS and the IDENTIFY resolving under
515 heavy load by taking away unnecessary resolving for entries
516 that are being resolved already.
518 Added support for adding multiple pending commands for one
519 command idenfier. Affected file silcd/command[_reply].[ch].
521 * Fixed WHOIS and IDENTIFY save to remove the cache entry
522 before deleting the data. Otherwise the hash table will have
523 freed data in comparison functions. Affected file is
524 silcd/command_reply.c.
526 * Fixed silc_idlist_replace_client_id to add the new entry to
527 the cache with NULL nickname. Otherwise there will be invalid
528 memory as the nickname after the nickname is freed. Affected
529 file silcd/packet_receive.c.
531 * Fixed the silc_idlist_get_clients_by_hash. The entries was
532 saved into wrong slots because the previous number of entries
533 was not taken into account. Affected file silcd/idlist.c.
534 Fixed same thing in silc_idlist_get_clients_by_nickname too.
536 * If we are router and we receive JOIN notify to a channel that
537 does not have any users then notified client is marked as the
538 channel founder, as it is it. The affected file is
539 silcd/packet_receive.c
541 * Added to the extended hash table API's table_del_*ext functions
542 the destructor as argument too, so that the caller can decide
543 which destructor to use or whether to use destructor at all.
544 Affected file lib/silcutil/silchashtable.[ch].
546 * Fixed ID Cache purging. It actually deleted the entries from
547 the hash table after the data was freed. The hash table ended
548 up comparing freed memory. The affected file is
549 lib/silccore/silcidcache.c.
551 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
553 * Fixed Irssi SILC client's KILL command's HELP syntax.
555 * The USERS command now resolves the detailed user information
556 if the userinfo field is missing. Affected file is
557 lib/silcclient/command_reply.c.
559 * Do not print error in silc_file_read if the read file does
560 not exist. Just silently return NULL. Affected file is
561 lib/silcutil/silcutil.c.
563 * Fixed the silc_log_output to not wine about NULL filename
564 and to not create some bogus " " filename. Affected file is
565 lib/silcutil/silclog.c.
567 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Fixed various printing bugs on the user interface in the
570 Irssi SILC Client. Minor changes that were forgotten from
573 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
575 * Fixed the configure.in.pre and the compilation and distribution
576 environment to support the new autoconf 2.52. That version is
577 now required to compile the CVS trunk.
579 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Renamed function silc_parse_nickname to silc_parse_userfqdn
582 to generally parse user@fqdn format strings. Affected file
583 lib/silcutil/silcutil.c.
585 * Added nickname_format and nickname_force_format fields to the
586 SilcClientParams structure. The first one defines the format
587 for the nicknames that the library will enforce if the receives
588 multiple same nicknames. The second one is boolean value and
589 can be used to force the library to always enforce the format
590 to the nicknames regardles whether there are multiple nicknames
591 or not. This configurable formatting was employed to flexibly
592 support accessing multiple nicknames from the user interface.
593 The userinterface can now set the nicknames to what ever format
594 they prefer. Affected file lib/silcclient/silcapi.h.
596 Added function silc_client_nickname_format to the file
597 lib/silcclient/idlist.c. It performs the nickname formatting.
599 Added new field `hostname´ to the SilcClientEntry context.
600 It holds the hostname of the client. Affected file is
601 lib/silcclient/idlist.h.
603 * Irssi SILC Client sets the nicknames in nick@hostn format.
604 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
605 irssi/src/silc/core/silc-core.c.
607 The WHOIS printing now also shows both the real nickname and
608 the formatted nickname so that user knows how to access the
609 user if there are multiple same nicknames cached. Affected
610 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
611 printing formatting too to take the hostname now as a separate
612 argument. The Affected file is
613 irssi/src/fe-common/silc/modules-formats.[ch].
615 * Changed the silc_client_get_clients_local to accept the formatted
616 nickname as argument. It accepts the real nickname too but the
617 formatted nickname can be used to find the true entry from
618 multiple entries. Affected file lib/silcclient/silcapi.h and
619 lib/silcclient/idlist.c.
621 * Added nickname_format_parse field to the SilcClientParams.
622 It is a callback function provided by the application to parse
623 the nickname out of the formatted nickname string. The library
624 calls it to get the nickname from the formatted string. Since
625 the application generally knows better the format of the nickname
626 string it parses it instead of the library, even though library
627 encodes the formatted string. If the callback function is not
628 provided then the library will use the string as is. The
629 affected file is lib/silcclient/silcapi.h.
631 * All the nickname strings passed to the client library in
632 commands are now expected to be formatted nickname strings.
633 If the command does not support the formatted nickname string
634 it will assume that the sent string is the actual nickname.
635 Affected file lib/silcclient/command.c.
637 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
639 * Added public key authentication support to OPER and SILCOPER
640 commands in the client library. Affected file is
641 lib/silcclient/command.c.
643 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
645 * Changed the get_auth_methdod client operation to be asynchronous.
646 It can be async if the application resolves the authentication
647 method from the server during the negotiation. Added new
648 SilcGetAuthMeth completion callback that the application will
649 call after resolving the authentication method.
651 Added function silc_client_request_authentication_method that
652 the application can use to resolve the authentication method
653 from the server. Added also SilcConnectionAuthRequest callback
654 that the library will call after the server has replied. The
655 application can call this function if it does not know the
656 current authentication method.
658 Affected files are lib/silcclient/client.c and
659 lib/silcclient/silcapi.h.
661 * The Irssi SILC client now automatically resolves the authentication
662 method incase any configuration information is not present (and
663 currently there never is). The affected file is
664 irssi/src/silc/core/client_ops.c.
666 * Fixed public key authentication from the client library.
667 Affected file lib/silcclient/protocol.c. Changed also the
668 protocol specification about the public key authentication in
669 the connection authentication protocol. The actual data to be
670 signed is now computed with a hash function before signing.
672 * Fixed the public key authentication from the server as well.
673 Affected file silcd/protocol.c.
675 * Removed the mlock()'s from the memory allocation routines.
676 Affected file lib/silcutil/silcmemory.c. The ./configure does
677 not check anymore for the mlock(). Affected file is
680 * Fixed USERS command in server to allow the execution of the
681 command for private and secret channels if the client sending
682 the command is on the channel. Affected file silcd/command.c.
684 * Fixed silc_client_get_clients_local to return the clients
685 count correctly. It could return wrong value. Affected file
686 lib/silcclient/idlist.c.
688 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
690 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
691 types. The assembler optimizations seemed not to like 64-bit
692 data types. The assmebler optimizations thus are now enabled
693 also for BSD systems as opposed to only enable them for Linux.
695 * Do not check for threads at all on BSD systems. Affected
696 file configure.in.pre.
698 * Removed -n and -h options from the Irssi SILC Client since
699 they are not used in silc.
701 * Fixed the prime generation to assure that the first digit
702 of the generated random number is not zero since our conversion
703 routines does not like number strings that starts with zero
704 digit. If zero digit is seen the random number is regenerated.
705 This caused some corrupted RSA keys when the zero first digit
706 was met. Affected file lib/silcmath/silcprimegen.c.
708 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Fixed WIN32 configuration in the ./configure script.
711 Fixed to include xti.h on environments that has it.
712 Patches by Carsten Ilchmann and andrew.
714 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
716 * Changed the silc_id_create_client_id to be collision
717 resistant. It is now assured that there cannot be created
718 two same client ID's. I suspect that some weird bugs in
719 the server were actually caused by duplicate Client IDs.
720 Affected file silcd/serverid.[ch]. A router receiving
721 new ID now also assures and informs the sending server
722 if the ID caused collision.
724 * Changed the silc_id_create_channel_id to also assure that
725 there are no collisions.
727 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Statement about ignoring the Mutual Authentication flag when
730 performing rekey with PFS was a bit misleading. It is ignored
731 if it was set in the initial negotiation, it cannot be even
732 set in the rekey. Fixed in the ke-auth draft. Started the
733 new versions of the protocol drafts in the doc/.
735 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Fixed a bug in silc_client_command_identify_save when saving
738 new channel information. The channel name was no duplicated
739 and caused crash on exit. Affected file is
740 lib/silcclient/command_reply.c.
742 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Fixed the getkey command handling in the server. Send just
745 empty OK reply to the sender if the key could not be fetched
746 (but everything else was ok, like the key just was not available).
747 Changed the public key parameter to optional in the protocol
748 specs so that empty OK reply can be sent. Affected file
751 Added a message to Irssi SILC client to tell to user if the
752 server did not return a public key.
754 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Fixed a channel key regeneration bug. It registered new
757 timeout tasks exponentially until all system resources were
758 used. Affected file silcd/server.c.
760 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
762 * Added the SILC Document generator to the scripts/silcdoc.
763 It can be used to generate the Toolkit Reference Manual out
764 of the source tree. Internally it will also use the RoboDoc
765 generator now imported in util/robodoc.
767 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
769 * Added couple of return's in rekey protocol if error orccurred
770 during the protocol. The execution must be terminated.
771 Affected file silcd/protocol.c. Also, terminate the protocol
774 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
776 * The client's Client ID was created initally from the wrong
777 nickname (it could have been in format nick@host) in the
778 silc_server_new_client. Affected file silcd/packet_receive.c
780 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Added some SILC_LOG_ERROR's to various error conditions
783 if client could not be added to ID cache. Affected files
784 silcd/packet_receive.c and silcd/server.c.
786 * When client's sock->user_data is freed, NULL also the
787 client->router and client->connection pointers. Added check
788 for these pointers being NULL to various places around the
789 code. Affected file silcd/server.c.
791 * Added client->data.registered == TRUE checks to various
792 places around the code to assure that unregistered client's
793 are not handled when it is not allowed. Affected file
796 * Added `bool registered' fields to all
797 silc_idlist_[server|client]_get_* routines to indicate whether
798 the fetched client needs to be registered or not. Affected
799 file silcd/idlist.[ch].
801 * Add your own entry as registered to the ID cache in the
802 server. Affected file server.c.
804 * Fixed a bug in silc_server_new_server. The SilcServer was
805 set as the new server's context instead of SilcServerEntry.
806 This naturally caused some weird bugs.
808 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
810 * Do not delete the channel rekey task when adding it
811 for in silc_server_create_channel_key.
813 * Changed the silc_server_create_channel_key to return
814 TRUE or FALSE to indicate the success of the channel key
817 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Fixed MSVC++ project files and added missing files to
820 Makefiles under win32/.
822 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Do not add TCP_NODELAY flag if the operating system
825 does not have it defined. Affected files are
826 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
828 * Fixed buffer overflow from Irssi SILC Client. Affected
829 file irssi/src/fe-common/core/themes.c.
831 * Fixed double free in client library in the file
832 lib/silcclient/client.c when disconnecting from server.
834 * Applied double free patch from cras to Irssi SILC client.
835 Affected files irssi/src/core/[modules/expandos].c
837 * Fixed the disconnection handling to Irssi SILC Client.
838 The application must call silc_client_close_connection
839 in ops->connect client operation in case of failure of
840 the connection. Affected file is
841 irssi/src/silc/core/client_ops.c.
843 * Do not set sock->protocol to NULL in the function
844 silc_client_close_connection after executing the protocol's
845 final callback since the sock might not be valid anymore.
846 Affected file lib/silcclient/client.c.
848 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Do not enable SILC_THREADS if the linking with libpthread
851 did not happen. Affected file configure.in.pre.
853 * Added notion to protocol specification that server must
854 verify the sent authentication payload with CMODE when
855 setting the channel founder key. Implemented it to the
856 server. Affected file silcd/command.c.
858 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
860 * Added _EXTRA_DIST SILC distribution variable to the
861 distributions file. It is used to conditionally add extra
862 files or directories to the specific distribution. Affected
863 files ./prepare, Makefile.am.pre and distributions.
865 Removed the `_' from the start of the distribution names.
868 * Added README.WIN32 for instructions to compile the Toolkit
871 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Fixed a double free in disconnection in the server. Affected
874 file is silcd/server.c.
876 * Fixed the lib/silcske/groups.c to work now also with GMP
877 MP library. The string conversion did not work when using
878 specific base and the base is indicated in the string as well.
880 * Created win32/ directory which now includes MSVC++ specific
881 stuff so that toolkit (DLLs) may be compiled with MSVC++.
882 It will appear only in the toolkit distribution
884 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
886 * Changed the key material distribution function in case when
887 the hash output is too short. The data is now concatenated
888 a bit differently than it used to. Made the change to the
889 SKE protocol specification.
891 * Added better GMP detection to configure.in.pre. A patch
894 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
896 * Fixed a minor bug in SKE that might cause some problem on
897 some platforms. Affected file lib/silcske/silcske.c.
899 * Added the cookie checking for initiator in the SKE. It checks
900 that the responder returns the sent cookie unmodified. The
901 affected file is lib/silcske/silcske.c. Added new SKE
902 error type INVALID_COOKIE that can be sent during the
903 negotiation. Fixed some memory leaks as well.
905 * Added the "invalid cookie" error message to Irssi SILC client's
908 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Added `task_max' field to the SilcClientParams to indicate
911 the maximum tasks the scheduler can handle. If set to zero,
912 default values are used. Affected file lib/silcclient/silcapi.h.
914 * Fixed memory leaks in silc_client_close_connection. Affected
915 file lib/silcclient/client.c.
917 * Added silc_client_del_client_entry to client library to free
918 all memory of given client entry. Affected file is
919 lib/silcclient/idlist.[ch].
921 * Added new functions silc_client_del_channel and
922 silc_client_del_server to delete channel and server entries.
923 Affected file lib/silcclient/[silcapi.h/idlist.c].
925 * Removed silc_client_del_client_by_id from silcapi.h.
927 * Fixed the INFO command to return the server's own info
928 correctly when querying by Server ID. Affected file is
931 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
933 * Removed the non-blocking settings in WIN32 code in the
934 silc_sock_[read/write] and added SleepEx instead. Affected
935 file lib/silcutil/win32/silcwin32sockconn.c. The availability
936 of input data is now checked with FIONREAD and ioctlsocket.
938 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Call silc_schedule_task_del_by_context in the
941 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
942 Affected file lib/silccore/silcprotocol.c.
944 * Call silc_protocol_cancel for active protocols in the
945 silc_server_close_connection if the funtion
946 silc_server_free_sock_user_data has not been called.
947 Affected file silcd/server.c.
949 * Generic tasks cannot be deleted using the del_by_fd
950 task deleting function since generic tasks does not match
951 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
953 * Added a notion to SILCOPER help file that the SILCOPER works
954 only on router server, not on normal server.
956 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Added for WIN32 support for the new scheduler as well.
959 Affected file lib/silcutil/win32/silcwin32schedule.c.
961 * Fixed the SHA1 implementation to work on various platforms.
963 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
965 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
966 API. It is part of the scheduler now. Everything else is
967 as previously but some functions has changed their names.
968 Checkout the lib/silcutil/silcschedule.h for the interface.
969 Updated all applications to use the new interface. Affected
970 files are lib/silcutil/silcschedule.[ch].
972 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
974 * Found a bug in the SKE implementation. The HASH value,
975 specified by the protocol, was not computed correctly. The
976 public key of the responder was not added to the computation
977 even though it is mandatory. Affected file lib/silcske/silcske.c.
978 This unfortunately causes incompatibilities with older
981 * Added WIN32 specific network init and uninit functions:
982 silc_net_win32_init and silc_net_win32_uninit to init and uninit
983 the Winsock2. Affected file lib/silcutil/silcnet.h and
984 lib/silcutil/win32/silcwin32net.c.
986 * Set the socket always to nonblocking mode on WIN32 after
987 reading data or writing data. Affected file is
988 lib/silcutil/win32/silcwin32sockconn.c.
990 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Fixed various compilation problems under WIN32. Affected
993 files lib/silcutil/win32/silcwin32thread.c and
994 lib/silcutil/win32/silcwin32schedule.c.
996 * Removed all _internal.h #includes from public header
997 files. Internal headers must never be included from
1000 Removed also the lib/silcske/payload_internal.h file.
1002 * All include files that may be needed (public and some others
1003 included by the public headers) by application developers are
1004 now copied to the ./includes directory. It does not copy any
1005 internal headers. Affected file Makefile.defines.pre and all
1006 Makefile.am's under lib/ and subdirs.
1008 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * Do not change the ~/.silc directory's permissions automatically.
1011 Affected file irssi/src/silc/core/clientutil.c.
1013 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Do not cancel the protocol in silc_server_close_connection
1016 it might cause recursion. Now cancelled in the function
1017 silc_server_free_sock_user_data. Affected file silcd/server.c.
1019 * Fixed the silc_server_remove_clients_by_server to regenerate
1020 the channel keys correctly finally. Added also new function
1021 silc_server_remove_clients_channels to actually do it.
1022 Affected file silcd/server.c.
1024 * Fixed the silc_server_new_channel to not crash by giving
1025 wrong router to the new channel. Affected file is
1026 silcd/packet_receive.c.
1028 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1031 which is given as argument to the silc_client_alloc now.
1032 It can be used to configure the client and set various parameters
1033 that affect the function of the client.
1035 * The USERS command in server did not check whether the channel
1036 is private or secret. Affected file silcd/command.c.
1038 * Added new argument to the USERS command in protocol specification.
1039 The USERS command now can take the channel name as argument
1040 as well. Added support for this in client and server and
1041 updated the protocol specs.
1043 * Completed the GETKEY command in client. It can be now used
1044 to fetch also servers public key not only some clients.
1045 Affected files lib/silcclient/command[_reply].c.
1047 * Added silc_client_get_server to return server entry by the
1048 server name. Affected files lib/silcclient/silcapi.h and
1051 * Redefined the IDENTIFY command in protocol specification to be
1052 more generic. It now can be used to query information about
1053 any entity in the SILC Network, including clients, servers and
1054 channels. The query may be based either the entity's name
1055 or the ID. Added support for this in both client and server.
1057 Affected files silcd/command.c and lib/silcclient/command.c
1058 and command_reply.c.
1060 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1061 the _from_client and _from_server functions. Affected file
1064 * Added silc_client_get_channel_by_id_resolve to the file
1065 lib/silcclient/silcapi.h to resolve channel information by
1066 its ID. Added also silc_client_get_channel_by_id that
1067 does not resolve it from the server.
1069 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Added SilcServerEntry context into the client library
1072 to represent one server. The INFO command now allocates
1073 these to save the resolved server info. For now on the
1074 client library will also keep information about servers,
1075 connected and resolved with INFO.
1077 The INFO command now allocates the SilcServerEntry context
1078 and saves the server info there. The COMMAND_REPLY in
1079 the INFO now returns the parameters to application in
1080 same order as defined in the protocol specification.
1082 The entries are cached in the client->server_cache.
1084 * The INFO command is now issued after received the Client ID
1085 from the server. Affected file lib/silcclient/client.c.
1087 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1088 to the application as the mode changer might be server.
1089 It is guaranteed that NULL is not returned anymore to the
1090 application. Affected file lib/silcclient/client_notify.c.
1092 The ID Type is now also passed to the application so that
1093 it can check whether the returned entry is SilcClientEntry
1096 Added new function silc_client_get_server_by_id to return
1097 the server entry by ID. Affected files are the
1098 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1100 * Do not create the channel in the Irssi SILC Client when issuing
1101 the JOIN command but when received the sucessful JOIN command
1102 reply. Otherwise the channel might get created even though we
1103 could not join it. The Affected file is
1104 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1106 * Fixed a channel joining bug in router. The router must also
1107 check the channel modes, invite and ban lists etc. when serving
1108 the JOIN command sent by normal server. Affected file is
1109 silcd/command.c. The router now resolves the client's
1110 information from the server who sent the JOIN command if it
1111 does not know it, and processes the JOIN command only after
1114 * Changed the SilcCommandCb to take new argument; void *context2.
1115 Affected file lib/silccore/silccommand.h
1117 The second argument in the command callbacks in the server now
1118 includes the SilcServerCommandReplyContext if the command was
1119 called as pending command callback from the command reply.
1120 Otherwise it is NULL. When called as pending the status of the
1121 command reply will be checked and if it was erronous the
1122 error will be sent to the original sender of the command.
1123 This way the client always receives the error messages even
1124 though the server was actually the one who received the error
1125 when it resent the command to router, for example. Affected
1126 files silcd/command[_reply].[ch].
1128 * Fixed sending WHOWAS command's error message to client if
1129 the requested client could not be found. It was missing.
1132 * Changed the CMODE and CUMODE commands reply arguments in the
1133 protocol specification. The Channel ID is now sent in both
1134 of the commands to identify the channel. Implemented this
1135 new feature to the client and server. Affected files
1136 lib/silcclient/command_reply.c and silcd/command.c.
1138 * Made better checks for invite and ban lists in the JOIN
1139 command in server. Affected file silcd/command.c.
1141 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * The server now performs the incoming host IP/DNS lookup
1144 using the silc_socket_host_lookup and thus does not block
1145 the server anymore. Affected file silcd/server.c.
1147 * Completed the multi-thread support for SILC Scheduler in
1148 the lib/silcutil/silcschedule.c.
1150 * Fixed the configure.in.pre to detect the pthread correctly
1153 * Fixed a deadlock in silc_task_queue_wakeup in the file
1154 lib/silcutil/silctask.c.
1156 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Added new function silc_schedule_wakeup that is used in
1159 multi-threaded environment to wakeup the main thread's
1160 schduler. It needs to be used when a thread adds a new task
1161 or removes a task from task queues. After waking up, the
1162 scheduler will detect the task queue changes. If threads
1163 support is not compiled in this function has no effect.
1164 Implemented the wakeup mechanism to both Unix and WIN32
1165 systems. Affected files are lib/silcutil/silcschedule.[ch],
1166 lib/silcutil/unix/silcunixschedule.c and the
1167 lib/silcutil/win32/silcwin32schedule.c.
1169 * Added new function silc_task_queue_wakeup to wakeup the
1170 scheduler by the specified task queue. Affected file
1171 lib/silcutil/silctask.[ch].
1173 * The silc_socket_host_lookup_start now wakes up the scheduler
1174 after adding the timeout task. Affected file is
1175 lib/silcutil/silcsockconn.c.
1177 * The silc_socket_host_lookup is synchronous now if the threads
1178 support is not compiled in. However, the callback is still
1179 called asyncronously through the scheduler, anyway. Affected
1180 file lib/silcutil/silcsockconn.c.
1182 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1184 * Added new function silc_socket_host_lookup to perform
1185 asynchronous IP and FQDN lookups for the socket connection.
1186 Affected files lib/silcutil/silcsockconn.[ch].
1188 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1191 that may or may not compile the mutex support in.
1193 Changed the silc_mutex_alloc interface. It allocates the
1194 mutex now to the sent pointer and returns TRUE or FALSE.
1196 Affected file lib/silcutil/silcmutex.h.
1198 * Wrote the SILC Task Queue interface to support multi-threads.
1199 Affected file lib/silcutil/silctask.[ch].
1201 * Wrote the SILC Scheduler to support multi-threads. Affected
1202 file lib/silcutil/silcschedule.c.
1204 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1207 in lib/silcutil/win32/.
1209 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1211 * Defined SILC Mutex API and SILC Thread API and implemented
1212 them for Unix. Affected files are
1213 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1214 lib/silcutil/unix/silcunixmutex.c and
1215 lib/silcutil/unix/silcunixthread.c.
1217 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Fixed the silc_server_remove_clients_by_server's channel
1220 key re-generation. The hash table handling was incorrect
1221 and would not work with many channels. Affected file is
1224 * Fixed some memory leaks around the server code.
1226 * Rewrote the silc_server_get_users_on_channel to support IPv6
1227 based Client ID's. Affected file silcd/server.c.
1229 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1230 specification. However, a separate document must be written
1231 to define the detailed signing procedure and the payload
1232 associated with the flag. Defined the flag to the
1233 lib/silccore/silcchannel.h as well.
1235 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Changed the dynamic tables to static size tables in the
1238 lib/silccrypt/silchmac.c.
1240 * Removed GCC dependencies from the code. A patch by cras.
1242 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Do not show the error "Error receiving packet bla bla"
1245 in server if it really was not an error (-2 means that reading
1246 is pending). Affected file silcd/server.c.
1248 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Fixed a possible crash in silc_server_remove_clients_by_server
1251 in silcd/server.c. Fixed there also some memory leaks.
1253 * Fixed the silc_idlist_replace_client_id. It could replace
1254 wrong key in the hash table. Affected file silcd/idlist.c.
1256 * Do not check whether there are global users on the channel
1257 if the channel->global_users is FALSE. Affected functions
1258 silc_server_remove_from_one_channel and
1259 silc_server_remove_from_channels in silcd/server.c. Also,
1260 do not check if the removed client is local as we can be
1261 sure that global client was not removed from the channel
1262 and checking for global users is not needed.
1264 * The silc_server_remove_clients_by_server now re-generates
1265 the channel keys correctly for those channels that had
1266 clients removed from them. Affected file silcd/server.c.
1268 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Found the reason of random crashes in the server. We weren't
1271 ignoring the SIGPIPE signal (which can be sent in write())
1272 and it crashed the server. Affected file silcd/silcd.c.
1274 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Assure that sock->user_data is not NULL in the function
1277 silc_server_packet_send in silcd/packet_send.c.
1279 * Disconnect the remote connection if it could not be added
1280 to any ID lists in the server. The affected file is
1283 * Check in silc_server_packet_send[_real/dest] that the
1284 socket is not disconnecting and ignore the data if it is.
1285 Affected file silcd/packet_send.c.
1287 * Define inline to __inline on native WIN32 compilation.
1288 Affected file includes/silcwin32.h.
1290 * Added some explicit type casts for inline code since MSVC
1291 require them. Affected files lib/silcutil/silcbuffer.h,
1292 lib/trq/silcdlist.h and lib/trq/silclist.h.
1294 * Print warning in log files from now on if the packet
1295 decryption fails. Affected file silcd/server.c.
1297 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1299 * Changed the `say' client operation's interface to accept
1300 new `type' argument to indicate the type of the message sent
1301 by the library. The application may filter the library's
1302 messages according the type. The affected file is the
1303 lib/silcclient/silcapi.h.
1305 * Added two new functions to lib/silcclient/silcapi.h:
1306 silc_client_del_client and silc_client_del_client_by_id.
1307 Affected file lib/silcclient/idlist.c.
1309 * Moved the clientincludes.h from includes/ to silc/ and
1310 serverincludes.h from includes/ to silcd/.
1312 * The modes for the CMODE and CUMODE are now passed as
1313 uint32 for application with COMMAND_REPLY. The affected
1314 file is lib/silcclient/command_reply.c.
1316 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * /WHOIS without arguments shows client's own information.
1319 Affected file lib/silcclient/command.c.
1321 * Changed PING to not accept any arguments. The specs
1322 says that client can ping only the connected server so
1323 requiring an argument is not needed. Affected file is
1324 lib/silcclient/command.c.
1326 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Fixed a fatal bug in private message sending and reception
1329 encryption and decryption when using private message keys.
1330 The implementation was incorrect and did not follow the
1331 specification. It causd that some of the message were
1332 lost since it did not use the sending and receiving keys
1333 as the protocol suggests. This has been fixed and will cause
1334 incompatibilities with older clients when sending private
1335 message encrypted with private message keys. Affected files
1336 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1337 and various other in Irssi SILC Client.
1339 Added `responder' boolean argument to the functions
1340 silc_client_add_private_message_key[_ske] to indicate when
1341 the key is added as responder or initiator of the key
1344 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Removed the silc_ske_check_version function and created
1347 a SilcSKECheckVersion callback. Added also a function
1348 silc_ske_set_callbacks that is now used to set all SKE
1349 callbacks. The callback functions are not given to
1350 the SKE functions anymore, but this function is used to
1353 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1355 * Added `silc_version' argument to the silc_client_alloc
1356 to define the version of the application for the library.
1357 The library will use the version string to compare it
1358 against the remote host's (usually a server) version
1359 string. Affected file lib/silcclient/silcapi.h
1361 * Added the KE protocol context to Key Agreement context
1362 in client library so that we can abort the SKE if it
1363 is in process when we get timeout. Affected file is
1364 lib/silcclient/client_keyagr.c.
1366 * Do not resolve the client ID forever if it returns in the
1367 first time that such client does not exist. This was done
1368 for example with private message. Affected file is
1369 lib/silcclient/client_prvmsg.c.
1371 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Do not add regex.h for WIN32. The affected file
1374 includes/silcincludes.h.
1376 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1377 not work yet 100%. It generates the DLL's automatically
1378 when compiling with --with-win32 under cygwin.
1380 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1382 * lib/contrib/regex.c is not compiled on WIN32.
1384 * Added silc_net_get_socket_opt function to the
1385 lib/silcutil/silcnet.h.
1387 * Added includes/silcwin32.h for WIN32 specific includes
1390 * Do not use ptime structure or any of the posix process
1391 functions on WIN32 in lib/silccrypt/silrng.c.
1393 * Added silc_gettimeofday to provide generic function
1394 for struct timeval on all platforms. Added the function
1395 to lib/silcutil/silcutil.h.
1397 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1400 library as they clearly belong there. As a plus side we
1401 can make the actual socket connection routines platform
1404 Added also new generic function silc_socket_read and
1405 silc_socket_write (that used to be silc_packet_[read/write].
1406 The implementation of these are platform specific.
1408 * Added WIN32 specific routines of silc_socket_[read/write]
1409 to lib/silcutil/win32/silcwin32sockconn.c.
1411 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Added preliminary support for native WIN32 compilation under
1414 cygwin (using the -mno-cygwin option for GCC) to the
1415 ./configure.in.pre. The --with-win32 now prepares the
1416 compilation for native WIN32.
1418 * Rewrote the SILC Scheduler interface in the file
1419 lib/silcutil/silcschedule.h. The scheduler is now context
1420 based and does not have anymore any global static scheduler.
1421 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1422 and created lib/silcutil/win32 directory for WIN32 based
1425 * Added Unix specific network routines to the
1426 lib/silcutil/unix/silcunixnet.c and the old
1427 lib/silcutil/silcnet.c includes now only generic routines.
1429 Added WIN32 specific network routines to the
1430 lib/silcutil/win32/silcwin32net.c.
1432 * Added Unix specific utility functions from the
1433 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1435 * Added WIN32 SILC Scheduler to the file
1436 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1439 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Do not handle JOIN notify in the server if the target client
1442 is not registered (idata->registered == FALSE). The affected
1443 file is silcd/packet_receive.c.
1445 * Update the nickrec->founder in event_cumode in the Irssi SILC
1446 client. Affected file irssi/src/silc/core/silc-channels.c.
1448 * Fixed the CUMODE_CHANGE notify handling in the server when
1449 server and router are announcing their clients on channels.
1450 Now the mode changes are saved and notified correctly. The
1451 affected file is /silcd/packet_receive.c.
1453 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1454 They really did not replace the cache entry in the ID Cache.
1455 Now they do that. Affected file silcd/idlist.c.
1457 * Fixed the KICK notify handling in the Irssi SILC client to
1458 update the channel records so that the kicked client does not
1459 appear to be on the channel. The affected file is
1460 irssi/src/silc/core/silc-channels.c.
1462 * Always update the conn->current_channel when executing command
1463 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1465 * Fixed the KILL notify handling in Irssi SILC client to remove
1466 the killed client on all channels.
1468 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1470 * Fixed the silc_parse_command_line to remove extra spaces
1471 from the start and end of the arguments. Affected file is
1472 lib/silcutil/silcutil.c.
1474 * Cancel and free any active protocol in the function
1475 silc_server_close_connection. Affected file silcd/server.c.
1477 * Cancel and free any active protocol in the function
1478 silc_client_close_connction. Affected file is
1479 lib/silcclient/client.c.
1481 * Do not execute the KILL command for clients that are in
1482 history (ie. they are not in the network). Affected file is
1485 * Fixed KILL notify handling, client does not crash anymore.
1486 Affected file irssi/src/silc/core/silc-channels.c.
1488 * Reduced the default packet buffer size from 2048 to 1024 in
1489 lib/silccore/silcpacket.c.
1491 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1492 counter to the SKE context that is incresed when the SKE library
1493 performs async operation outside the library. If the outside
1494 process frees the SKE context and FREED status will be set
1495 and the library will detect after the sync operation that the
1496 libary is freed. The affected files are
1497 lib/silcske/silcske[_status].[ch].
1499 * Resolve the client entry information in the function
1500 silc_client_channel_message to assure that NULL pointer is not
1501 passed as client entry to the application. */
1503 * Fixed the task timeout calculation to assure that there is
1504 never negative timeouts. The affected file is
1505 lib/silcutil/silcschedule.c.
1507 * Fixed the channel user mode notification sending in server.
1508 It was sent point-to-point to the router (or to server by router)
1509 but it needs to be destined to a channel. The routines now
1510 supports sending the channel user mode notifys to the channels
1511 when announcing clients and channels. Affected files are
1512 silcd/server.c and silcd/packet_receive.c.
1514 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1515 It did not actually replace the old channel entry in the cache.
1516 Affected file lib/silcclient/client_notify.c.
1518 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * Fixed a possible crash in silc_packet_send_prepare. It now
1521 assures always that there is enough space in the buffer and
1522 at the tail area of the buffer (for MAC).
1524 Fixed the inbound buffer reallocation in silc_packet_read.
1525 It was old code and did not handle the reallocation correctly.
1528 The affected file is lib/silccore/silcpacket.c.
1530 * Fixed buffer overflow in silc_parse_nickname in the file
1531 lib/silcutil/silcutil.c.
1533 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * make install generates new server keys only if there is not
1538 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1541 Added check that if the NOREPLY is set then we will not send
1542 the away message. This avoids infinite loop of away messages
1543 if both clients are away. The affected file is
1544 lib/silcclient/client_prvmsg.c.
1546 * Fixed client crash if /NICK was given without arguments.
1547 Affected file lib/silcclient/command.c.
1549 * Server does not send the invite list in INVITE command back
1550 to the client if the list was not altered. Added this notion
1551 to the protocol spec as well. Affected file silcd/command.c.
1553 Fixed possible crash in INVITE command by checking the
1554 value of silc_server_get_client_route command.
1556 * Fixed the INVITE notify type handling. The arguments are now
1557 taken in correct order and client does not crash. The affected
1558 file is irssi/src/silc/core/silc-channels.c.
1560 Removed the "Inviting xxx to channel" message from the
1561 client library away and let the application handle it.
1562 Affected file lib/silcclient/command.c. Added that message
1563 to Irssi SILC client's message formats.
1565 * Fixed CMODE command crash in client. It now checks the
1566 amount of arguments correctly and does not crash. The affected
1567 file is lib/silcclient/command.c.
1569 * Do not create new channel automatically in silc_channels_join
1570 but check whether the channel by that name already exists.
1571 Affected file irssi/silc/core/silc-channels.c.
1573 * Do not send the SERVER_SIGNOFF to router if the disconnected
1574 entity was the router. Affected file silcd/server.c.
1576 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1577 SILC client as it was missing from there.
1579 Added the handling of the KICK notify to the Irssi SILC client
1580 as it was missing. Added "you have been kicked" message to
1581 Irssi SILC client's message modules formats.
1583 Added the handing of the KILL notify to the Irssi SILC client
1584 as it was missing. Added the kill message module formats
1587 The affected file is irssi/src/silc/core/silc-channels.c.
1589 * The router did not save the channel mode the server announced.
1590 Affected file silcd/packet_receive.c.
1592 * Fixed a possible crash in INFO command in server. If the
1593 server did not provide the server info it crashed. Affected
1594 file silcd/command.c.
1596 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Fixed the GETKEY command in the server to check also the
1599 global list. Otherwise the GETKEY would not work correctly
1600 in normal SILC server. Affected file silcd/command.c.
1602 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Fixed GETKEY crash, it crashed if the command did not succseed.
1606 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1609 is now real and not just an macro interface to GMP.
1611 Removed the entire GMP from the source tree and imported new
1612 NSS MPI library instead. Reason for removing GMP is that it is
1613 extremely large and compiles extremely slow. The NSS MPI
1614 is only a few files and compiles in less than 10 seconds.
1615 The speed is also about the same as GMP. The MPI is imported
1616 to lib/silcmath/mpi.
1618 If the system has GMP installed we will still use the GMP.
1619 If it is not then the NSS MPI will be compiled.
1621 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1623 * Merged a long nickname (127 characters long) crash bugfix from
1624 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1626 * Merged a freed memory reference bugfix from Irssi CVS tree.
1627 Affected file irssi/src/core/commands.c.
1629 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Added the server's public key sving and verification to the
1632 server when performing the SKE. This was missing and the
1633 remote server's (or router's) public key was accepted without
1634 checking whether we have it previously or trust it at all.
1635 Affected file silcd/protocol.c.
1637 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Check in the silc_server_timeout_remote if protocol is active
1640 and make sure that the protocol's final callback is called so
1641 that all memory if freed. Affected file silcd/server.c.
1643 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * silc_server_whois_send_reply crashed the server if the nickname
1646 was 127 characters long. Affected file silcd/command.c.
1648 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Added sanity check to the silc_server_new_client. If the hostname
1651 is provided inside username then check that the provided hostname
1652 really is the same as the resolved one. If the hostname was not
1653 resolved then check it from the public key. Affected file is
1654 silcd/packet_receive.c.
1656 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1657 if the server disconnected us and the connection is not valid
1658 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1660 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1661 the library to the lib/silcutil/silcutil.[ch].
1663 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Close log file after open. Affected file
1666 lib/silcutil/silclog.c.
1668 * Check whether sock == NULL in silc_client_send_packet and return
1669 if it is. Affected file lib/silcclient/silcclient.c.
1671 * Check rec->entry == NULL in the Irssi SILC Client before
1672 sending the channel message. Affecte file is
1673 irssi/src/silc/core/silc-servers.c.
1675 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Merged a splitted window bugfix from Irssi CVS tree. The
1678 affected file is irssi/src/fe-text/textbuffer-view.c.
1680 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1681 It did not print nickname.
1683 * Improved the distributions system a bit.
1685 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1688 irssi/src/fe-text/gui-window.c.
1690 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1691 to in-active server. The affected file is
1692 irssi/src/silc/core/client_ops.c.
1694 * Resolve the client in USERS command reply if the entry does
1695 not have username resolved. The affected file is
1696 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1697 command to WHOIS command to really resolve stuff. The USERS
1698 is not used any more in any critical section so WHOIS can
1699 be used even though it might be slower than IDENTIFY.
1701 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1704 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Changed the protocol API a bit more consistent in the
1707 lib/silccore/silcprotocol.[ch].
1709 * Changed the following headers to ROBODoc format:
1711 lib/silccore/silcpayload.h
1712 lib/silccore/silcprotocol.h
1713 lib/silccore/silcsockconn.h
1715 All core library headers are now formatted.
1717 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Fixed a bug in Irssi SILC client; do not show that you are
1720 server/router operator if you really are not. Affected file is
1721 irssi/src/silc/core/client_ops.c.
1723 * Renamed silc_command_free_payload to silc_command_payload_free.
1724 Affected file lib/silccore/silccommand.h
1726 * Added silcmath.h to include the prototoypes of various routines
1727 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1730 * Changed the following headers to ROBODoc format:
1732 lib/silccore/silcchannel.h
1733 lib/silccore/silccommand.h
1734 lib/silccore/silcid.h
1735 lib/silccore/silcidcache.h
1736 lib/silccore/silcmode.h
1737 lib/silccore/silcnotify.h
1738 lib/silccore/silcpacket.h
1739 lib/silcmath/silcmath.h
1741 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Added checking to the server code not to start the server if
1744 ciphers and stuff are not configured properly. Affected files
1745 silcd/serverconfig.[h] and silcd/server.c.
1747 * Changed the layout of the header files of the public interfaces
1748 in the SILC libraries. The new layout supports ROBODoc
1749 documentation tool (and some others) so that it is easy to create
1750 a library reference manual. All the other headers and source
1751 code must still follow the CodingStyle document. Also source
1752 code must not include these ROBODoc stuffs, only the headers.
1753 Furthermore, all public interface headers must now be named
1754 by using `silc' prefix, example: silcapi.h, silccipher.h.
1755 Some files were renamed due to this. All the other headers
1756 must not be used as public interfaces. I will update the
1757 CodingStyle document later. Changed following headers, so far:
1759 lib/silcclient/silcapi.h
1760 lib/silccore/silcauth.h
1761 lib/silccore/silcprivate.h
1762 lib/silccrypt/silcdh.h
1764 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1768 * Removed silc_client_packet_send_flush from the client library
1769 as it is not needed. Affected file lib/silcclient/client.[ch].
1771 * Added printing of message of unresolved authentication method
1772 to the Irssi SILC client. Added it to the module formats.
1773 Removed the same message from the client library.
1775 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Added new distribution feature, DISTLABEL. Every distribution
1778 can define own preprocessor label that can be used in the
1779 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1780 file distributions, acconfig.h.pre and prepare.
1782 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Added Makefile.defines_int to include the actual definitions
1785 for Makefile.defines.in. Tested the new distribution system,
1786 created distributions and tested installation.
1788 * Added AWAY message printing to the Irssi SILC client. Added
1789 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1791 * Added SCONNECT command to call the SILC's CONNECT command.
1792 Cannot use CONNECT directly since Irssi uses that internally.
1793 Affected file irssi/src/silc/core/silc-servers.c.
1795 Added ACTION local command. It is same as ME command but takes
1796 the channel as mandatory argument.
1798 Rewrote some of the Irssi's help files to suite for SILC
1801 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Added Makefile.defines[.in] that should for now on be included
1804 in all Makefile.am file in the source tree. That file includes
1805 all common compilation definitions for SILC source tree.
1807 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Minor changes to the ./prepare script to change the package
1810 name according the distribution name to the configure.in.
1812 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1814 * Created new distribution system. Added file `distributions'
1815 that defines all the distributions that can be created out of
1816 the SILC source tree. The ./prepare script now reads that
1817 file to determine how to prepare the distributions. The
1818 first argument to the ./prepare is the name of the distribution
1819 and second is the version of the distribution. If given
1820 without arguments it creates the default (toolkit) distribution
1821 with the default version (defined in ./prepare).
1823 All Makefile.am files that are subject to the distributions
1824 are now named as Makefile.am.pre. These are ./Makefile.am
1825 and lib/Makefile.am. Others may be changed later.
1827 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Added invite list, ban list, some key management and connection
1830 error message printing to module formats in the Irssi SILC client.
1832 * Added new silc_client_set_away_message to set the away message
1833 that is back to the person who sent private message. The
1834 affected file lib/silcclient/silcapi.h and the
1835 lib/silcclient/client_prvmsg.c.
1837 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Fixed the private message sending in the Irssi SILC client,
1840 added local command KEY to the Irssi SILC client.
1842 Added key management and key agreement message formats to the
1843 irssi/src/fe-common/silc/module-formats.[ch].
1845 Added USERS (alias WHO) printing, server/router operator
1846 indication and LIST command printing to the module formats.
1848 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Fixed channel joining notify handling, cumode notify handling
1851 from Irssi SILC client.
1853 * Added SILC specific module-formats to the Irssi SILC client so
1854 that SILC specific message hilighting, colors etc is possible.
1855 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1857 Added channel mode, channel user mode, actions, notices,
1858 whois and whowas printing to the the module-formats.c.
1860 * Fixed a bug in channel deletion in the server. The channel
1861 is not left to the cache even if the channel founder auth mode
1862 is set when there are no users anymore on the channel. Affected
1863 file silcd/server.c.
1865 * The silc_net_localhost now resolves the entire hostname including
1866 the domain name. Affected file lib/silcutil/silcnet.c.
1868 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1870 * Changed the ask_passphrase client operation to be ascynchronous.
1871 It has now a completion callback and a context that the
1872 application must call after it has got the passphrase from
1873 the user. Affected files lib/silcclient/silcapi.h,
1874 lib/silcclient/protocol.c, lib/silcclient/command.c and
1877 Added SilcAskPassphrase callback that the application calls
1878 to deliver the passphrase to the library.
1880 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1881 The public key verification and especially a certificate
1882 verification is asynchronous procedure.
1884 Added new SILC_SKE_STATUS_PENDING status to indicate the
1885 request is pending and a callback will be called to finalize
1888 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1889 indicate that remote end did not send its public key (or
1890 certificate), even though we require it. Added check for this
1891 condition in the SKE. This was a security bug, now fixed.
1893 Defined new SilcSKEVerifyCbCompletion callback that is called
1894 when the verification process is completed.
1896 The affected files lib/silcske/silcske_status.h and
1897 lib/silcske/silcske.[ch].
1899 * Changed the verify_public_key client operation to be async
1900 as well. Defined SilcVerifyPublicKey callback that is used to
1901 indicate the success of the public key verification process.
1903 Changed the server and client to use the new async client
1906 * Changed the Irssi SILC client's internal scheduler to be called
1907 twice as many times as it used to be. As a result the client
1908 should be a bit faster now. Affected file is
1909 irssi/src/silc/core/silc-core.c.
1911 * Added support to Irssi SILC client of asynchronous public key
1912 verification and passphrase inquiry. Affected file is
1913 irssi/src/silc/core/silc-core.c.
1915 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * Do not say "You have left channel %s" in client library.
1918 Moved it to the application. Affected files are
1919 lib/silcclient/command.c and silc/client_ops.c.
1921 * Fixed silc_client_get_clients. Command context was not
1922 duplicated and was freed memory in the callback. Affected
1923 file lib/silcclient/idlist.c.
1925 * Do not say "you are now talking..." on JOIN command in the
1926 client library. The appliation must handle it.
1928 * Do not say ".. changed topic to" in command reply in the
1929 client libary. The application must handle it.
1931 * Fixed TOPIC command sending in the client library.
1933 * Fixed a memory leak in silc_client_command_free in the file
1934 lib/silcclient/command.c.
1936 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Imported a modified version of Irssi client to the source tree.
1939 The Irssi will be used to create a new client called
1940 Irssi SILC. Imported to irssi/.
1942 Added silc_core_init_finish function to the Irssi. Affected
1943 file irssi/configure.in.
1945 A lot changes in the Makefile.ams around the irssi tree.
1947 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Do not rehash if the new size is same as the old size of the
1950 hash table, in the silc_hash_table_rehash*. The affected file
1951 lib/silcutil/silchashtable.c.
1953 * Replaced hash_table_del_by_context calls from the server
1954 (when channel->user_list and client->channels) to the
1955 hash_table_del as it is sufficient and faster.
1957 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Added silc_hash_table_list, silc_hash_table_get and the
1960 SilcHashTableList structure to provide an alternative way to
1961 traverse the hash table. The affected files are
1962 lib/silcutil/silchashtable.[ch].
1964 * Changed the server's idlist routines to use the hash table
1965 routines to optimize the code.
1967 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1969 * Replaced the client entry's `channel' list and channel entry's
1970 `user_list' list to hash tables for optimized lookup. Changed
1971 the code to use the hash table interface around the code.
1972 Affected file lib/silcd/idlist.[ch].
1974 * Added `auto_rehash' boolean argument to the function
1975 silc_hash_table_alloc to indicate whether the hash table should
1976 auto-rehash when it thinks is appropriate time. It will
1977 increase the hash table size if the there is twice as much
1978 entries in the table than the size of the table, and will
1979 decrease the size if there are twice as less entries than
1980 the size of the table.
1982 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1986 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * silc_idcache_purge_by_context deletes the entry now by context
1989 as it is supposed to do. Affected file lib/silccore/idcache.c.
1991 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1992 client is not anymore valid (WHOWAS givens the info) and not
1993 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1995 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Removed the `data' and `data_len' arguments from the ID Cache
1998 interfaces and added `name' argument. ID Cache does not handle
1999 anymore the binary data only a names associated with given ID.
2001 * When hashing a Client ID with silc_hash_id the entire ID is
2002 not hashed anymore, instead only the hash of the Client ID is
2003 hashed. This way we can access the Client ID from the cache
2004 with Client ID but with the hash of the ID (which is a hash of
2005 the nickname) as well without any difference in performance.
2007 Added also silc_idcache_find_by_id_one_ext to do one on one
2008 searching when we have the actual ID. Added also function
2009 silc_hash_client_id_compare. The affected files are
2010 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2012 * When hashing the name associated with a ID it is always done
2013 in lowercase. This way we can access the cache without worrying
2014 about case-sensitivity, even though, for example nicknames are
2017 * Fixed a bug in server with channel message sending. It put
2018 wrong ID type as destination ID. The affected file
2019 silcd/packet_send.c.
2021 * silc_idcache_del_by_context now deletes from all hash tables
2022 by context. Affected file lib/silccore/idcache.c.
2024 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Changed the client library to use the new ID Cache interface.
2027 Changes around the source tree.
2029 * Added silc_hash_table_rehash_ext to rehash with specific
2030 hash function. Affected file lib/silcutil/silchashtable.[ch].
2032 * Added silc_hash_string_compare to compare two strings in the
2033 hash table. Affected file lib/silcutil/silcutil.[ch].
2035 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Added new function silc_idcache_del_by_context into the
2038 lib/silccore/idcache.[ch].
2040 * Changed the server's ID list routines to use the new ID Cache
2041 interface. Changes around the source tree.
2043 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Added silc_hash_table_del[_by_context]_ext functions in to the
2046 lib/silcutil/silchashtable.[ch].
2048 Removed silc_hash_table_find_all* routines and added new
2049 silc_hash_table_find_foreach to replace them.
2051 Added silc_hash_table_replace_ext function as extended
2052 replacing function. Separated the simple hash table interface
2053 from the extended hash table interface in the file
2054 lib/silcutil/silchashtable.h.
2056 * Fixed minor bugs and changed it to use some of the new
2057 hash table functions in lib/silccore/idcache.c
2059 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Added new function silc_hash_table_find_all to return all keys
2062 in the hash table by the specified key. As the hash table is
2063 collision resistant it also makes it possible to have several
2064 duplicate keys in the hash table. This function may be used to
2065 find all of the keys from the hash.
2067 Added user_context arguments to the SilcHashFunction,
2068 SilcHashCompare and SilcHashDestructor to deliver user specified
2071 Added new fuctions silc_hash_table_find[_all]_ext to do
2072 extended lookup with specified hash and compare functions and
2073 specified user contexts.
2075 Added new function silc_hash_table_add_ext to add the key
2076 with specified hash function and user context.
2078 Added new function silc_hash_table_foreach to traverse all
2079 entrys in the hash table. Added SilcHashForeach callback
2082 Added new function silc_hash_table_del_by_context to delete
2083 the entry only if the context associated with the key matches.
2085 Affected files are lib/silcutil/silchashtable.[ch].
2087 * Removed silc_hash_[server/client/channel]_id and added just
2088 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2089 silc_hash_id_compare to compare two ID's using as the hash table
2090 comparison function. Added also silc_hash_data to hash
2091 binary data and silc_hash_data_compare to compare it.
2093 * Removed silc_idlist_find_client_by_hash as it is not needed
2094 anymore. Affected file silcd/idlist.[ch].
2096 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2097 to use internally the SilcHashTable. The new ID Cache is a lot
2098 faster than the old one. Some of the ID Cache interface was also
2099 rewritten and obsolete and stupid functions were removed.
2101 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Added entry_count field to the SilcHashTable to keep the number
2104 of the entries in the table. Implemented the function
2105 silc_hash_table_rehash. Added new function
2106 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2108 Fixed a minor bug in silc_hash_table_free.
2110 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2111 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2112 into the lib/silcutil/silcutil.[ch].
2114 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2116 * Implemented a collision resistant hash table into the
2117 lib/silcutil/silchashtable[ch]. See the header and the source
2118 for the SilcHashTable API.
2120 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Merged dotconf version 1.0.2 into lib/dotconf.
2124 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Do not compile anything in lib/silcsim/* if the SIM support
2127 is not enabled. The tree should now compile without problems
2130 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Compiled the SILC under cygwin. Compiled and tested briefly
2133 without problems. More tests needed. The SIMs didn't compile
2136 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2138 * Fixed possible crash in silc_get_username in the
2139 lib/silcutil/silcutil.c.
2141 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Fixed a va_arg in silc/client_ops.c.
2145 * Oops, RC5 routines were named AES and caused some problems
2146 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2148 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Added new SilcIDIP structure into the lib/silccore/id.h and
2151 replaced the old `ip' fields from all SILC ID's to that type.
2152 This is a step towards IPv6 support.
2154 The silc_id_get_len takes now the ID as an extra argument.
2155 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2156 both IPv4 and IPv6 based ID's.
2158 The affected files are lib/silccore/id.[ch] and other files
2159 around the tree using these routines.
2161 * Removed the ID length arguments in server from various
2162 silc_server_send_notify_* routines -> they are not needed
2165 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Fixed memory leak in silc_encode_pem_file in the file
2168 lib/silcutil/silcutil.c.
2170 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Check minor version as well in the SKE. Affected files are
2173 silcd/protocol.c and lib/silcclient/protocol.c.
2175 * Added --identifier option to the server so that an identifier
2176 can be when creating the public key for the server. Affected
2177 file is silcd/silcd.c.
2179 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2180 lib/silccrypt/silcpkcs.c.
2182 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Register default ciphers and stuff when using -C option with
2185 the server. Affected file sildc/silcd.c.
2187 * Put back the servers public key filename format, it is better
2188 than the new one. For now, the client keys are saved with the
2189 new filename format. The affected file silc/client_ops.c.
2191 * Implemented the Cipher API for the rest of the ciphers that
2192 did not implement it or implemented it the wrong way.
2194 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * Register default ciphers and stuff when using the -S option
2197 in the client. Affected file silc/silc.c. Same also when
2198 creating new key pair with -C option.
2200 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Fixed the silc_verify_public_key client operation function to
2203 save the public keys differently. The fingerprint is now
2204 used as filename and not the hostname. This way also the
2205 client keys are saved uniquely and not with hostnames. The
2206 affected file is silc/client_ops.c.
2208 * Trimmed the silc_hash_fingerprint function to remove extra
2209 whitespaces from the end of the fingerprint. The affected
2210 file is lib/silccrypt/silchash.c.
2214 * Added silc_cipher_register_default function to register all
2215 default ciphers. It can be used when configuration files
2216 does not exist and the application does not want any specific
2217 ciphers in any specific order.
2219 The SilcDList is now used as silc_cipher_list dynamically
2220 allocated cipher list. Removed the static list all together
2221 and now all ciphers must be allocated to the dynamic list.
2222 The silc_cipher_alloc routine was changed to check only the
2225 All silc_cipher_* routines that used to return int returns
2228 The affected files lib/silccrypt/silccrypt.[ch].
2230 * The same thing was done to silc_hash_* as for silc_cipher_*
2231 routines. Affected files lib/silccrypt/silchash.[ch].
2233 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2234 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2235 Added also silc_pkcs_[un]register[_default] functions.
2236 Removed the data_context from the PKCS API.
2238 * Added silc_hmac_register_default function to register default
2239 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2240 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2241 to unregister all hmacs at once.
2243 * Register the default ciphers, hash functions, PKCSs and HMACs
2244 if client's configuration file does not exist. The affected
2247 * The client did not load the hash functions from the SIM
2248 modules at all. Added support for this. Affected file is
2249 silc/clientconfig.c.
2251 * When decoding public key with silc_pkcs_public_key_decode, check
2252 the supported algorithm only if PKCS are registered. Affected
2253 file lib/silccrypt/silcpkcs.c. The same was done with the
2254 silc_pkcs_private_key_decode.
2256 * Fixed the SILC List routines to keep the list always in order.
2257 It used to change the list's order when traversing the list but
2258 not it preserves the order. Affected file lib/trq/silclist.h.
2260 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Added the client library to use the SilcSocketConnection's
2263 reference counter (by silc_socket_dup) to prevent the bug that
2264 the socket object may be freed underneath async operation.
2266 * The name resolv library checking fixes in the configure.in.pre.
2269 * Created new version of the protocol drafts for future
2270 development. The -03 drafts are the ones that will be changed
2271 in the trunk now and the -02 will remain as they are.
2273 * Send list of CUMODE notifys to the router when announcing
2274 the channel users to the router. Affected file silcd/server.c.
2275 If the router receiving channel founder CUMODE for a channel
2276 that already has channel founder it will send CUMODE notify
2277 to the sender to remove the channel founder rights from the
2278 announced client. Affected file silcd/packet_receive.c.
2280 * The CUMODE notify may now use Server ID as well as the entity
2281 who changes the mode. Updated protocool specs.
2283 * Updated INSTALL and README files.
2285 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * New web pages in the http://silc.pspt.fi. The pages was
2292 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Implemented the [DenyConnectin] config section in the server.
2295 Added silc_server_config_denied_conn to check whether incoming
2296 connection is denied. Affected file silcd/serverconfig.[ch].
2298 * Do not check the ports when checking the incoming configuration
2299 data if the port is 0, meaning any. Affected file is
2300 silcd/serverconfig.c.
2302 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Fixed buffer overflow in silc_string_compare in the file
2305 lib/silcutil/silcutil.c.
2307 * Fixed double free in silc_server_command_leave in the file
2310 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Fixed the version checking in the server. Affected file is
2315 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Fixed the configuration data fetching when accepting new
2318 connections in the server. Affected file silcd/server.c.
2320 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added `sender_entry' argument to the function
2323 silc_server_packet_relay_to_channel so that we can check
2324 whether some destination actually belongs to the same route
2325 the sender belongs (ie, we must not resend the packet to the
2326 sender). Affected file silcd/packet_send.[ch].
2328 * Added `servername' field to the SilcClientEntry in the server
2329 to hold the name of the server where client is from. Affected
2330 file is silcd/idlist.h.
2332 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Moved the channel message encrypting in the router betwen
2335 router connections from silc_server_channel_message to the
2336 silc_server_packet_relay_to_channel since we want to check
2337 whether we have anybody channel before encrypting anything.
2338 Affected files silcd/packet_[receive/send].c.
2340 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Fixed the [AdminConnection] server config section to support
2343 multiple entries. Affected file silcd/serverconfig.c.
2345 * Added support into the server to check the validity of the
2346 incoming connection before executing any KE or authentication
2349 * The connection configuration is now saved to the KE and
2350 connection auth protocol contexts and not fetched anymore in
2351 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2353 * The local hosts listenning address and port is also resolved
2354 now when starting the server. We want to have the socket object
2355 to include the real address and port for the listener. Added
2356 new function silc_net_check_local_by_sock into the files
2357 lib/silcutil/silcnet.[ch].
2359 * Fixed a broadcast bug in server -> do not broadcast if we
2362 * Fixed a routing bug. Do not route broadcast packets ever.
2363 Broadcast packets must be processed always and not routed since
2364 they may be destined to some other host than yourself and thus
2365 would get routed without no good reason. Affected file is
2368 * Added function silc_server_config_is_primary_route to check
2369 whether primary router connection has been configured (a router
2370 configuration that we are initiating). If there is not, we
2371 will assume that there is only two routers in the SILC network
2372 and we will use the incoming router connection as our primary
2373 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2375 * Changed the order of the broadcasting. Broadcast _after_ the
2376 packet has been processed not before. Affected file is
2379 * Fixed a [ClientConnection] parsing bug. The port was never
2380 parsed correctly thus resulting to port 0. Affected file
2381 silcd/serverconfig.c.
2383 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2384 argument and did not set the broadcast packet flag. Affected
2385 file silcd/packet_send.c. Fixed same bug in the function
2386 silc_server_send_notify as well.
2388 * If we receive NEW_ID packet for our own ID in the server, ignore
2391 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Removed the nickname from the Private Message Payload.
2396 Updated the code and the protocol specs.
2398 * Updated protocol specs for submitting to the IETF.
2400 * Tweaked the Random Number Generator a bit. Affected file
2401 lib/silccrypt/silcrng.c. Exported a new function
2402 silc_rng_[global]_add_noise which can be used to add more
2405 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Do not parse packets with different timeout when protocol
2408 is active -> may cause problem with rekey. Affected file
2411 * When server receives signoff notify it must not create
2412 new channel key if the client is on any channels since the
2413 sender of the signoff notify will create it.
2415 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Added printing of error messages during SKE protocol from the
2418 failure packet sent by server during SKE. Affected file
2421 * Removed the client's failure_callback handling with timeout
2422 and handle it immediately when received.
2424 * The SKE library returned wrong type in SUCCESS and FAILURE
2425 packets. They must be 32 bit MSB not 16 bit MSB.
2427 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Ok, rewrote the logic of the re-key and now it seems to work.
2430 I tested it on high traffic with frequent re-keys without
2431 problems. Added hmac_receive (and renamed hmac to hmac_send)
2432 in SilcClientConnection in lib/silcclient/client.h and
2433 in SilcIDListData in silcd/idlist.h. Also, removed the
2434 SilcPacketParserContext's cipher and hmac fields as they are
2435 not needed anymore and actually caused some problems when
2436 the ciphers and hmac's changed underneath the packet parser.
2438 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * If re-key protocol is active then process the incoming packets
2441 synchronously since we must assure that icoming packets encrypted
2442 with the old key is processed before the new keys is set to
2443 use. This is true other packets than for REKEY packets.
2444 Affected file silcd/server.c. The same was done to client library
2445 as well, affected file lib/silcclient/client.c.
2447 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Fixed bug in client and server to accept the force send if
2450 the packet is send from silc_[server/client]_packet_process
2451 function. Otherwise the packets are never delivered, oops.
2453 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * Disable force sending of packets when REKEY protocol is active.
2456 We must assure that no packet is sent directly when rekey is
2457 performed. All packets must be sent through packet queue.
2458 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2459 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2460 function is silc_[server/client]_packet_send_real to check
2463 * Replaced the SIM paths from example config files to
2464 /usr/local/modules. Also, make install creates now
2465 /usr/local/silc/logs directory to hold all the SILC server
2468 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Made the configure.in.pre work on Solaris. Patch by salo.

2473 CBC mode macros into lib/silccrypt/ciphers_def.h.
2475 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Fixed the make install.
2479 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * When MAC computation fails the silc_packet_decrypt returned 0
2482 even though it was supposed to return -1. Fixed this. The
2483 affected file is lib/silccore/silcpacket.c.
2485 * Do not replace the config files in /etc/silc (in make install)
2486 if they already exist. Affected file ./Makefile.am.
2488 * Do not send re-key packets immediately but through packet queue.
2489 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2491 * Changed silc_net_check_host_by_sock to return FALSE if the
2492 IP/DNS could not be resolved. Though, it returns the IP address
2493 now even if it could not resolve it (but returns also FALSE).
2494 Affected file lib/silcutil/silcnet.[ch].
2496 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Added silc_pkcs_decode_identifier to decode the public key's
2499 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2500 Added also silc_pkcs_free_identifier. Added also new context
2501 SilcPublicKeyIdentifier.
2503 * Added -S option to the silc client. It is used to dump the
2504 contents of the specified public key file.
2506 * Changed the PKCS api to return the public key length when
2507 setting the public key.
2509 * Fixed a fatal bug in the public and private key file loading.
2510 Affected file lib/silccrypt/silcpkcs.c.
2512 * Execute the packet parsing for client with zero (0) timeout
2513 if the protocol is active. Affected file silcd/server.c.
2515 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Made the key generation options to the silcd program. Added
2518 -C option, equivalent to client's option.
2520 * Added new [ServerKeys] config section to the server. It
2521 configures the server's public and private key.
2523 * Defined generic Public Key Payload into the protocol
2524 specification to send specific type of public keys and
2527 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2528 public key or certificate.
2530 * Implemented the GETKEY command to the server and to the
2531 client library and on user interface.
2533 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2565 lib/silcclient/client.h.
2569 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * Do not ask whether user wants to use the negotiated private key
2572 for private messages, just use it. Affected file is
2573 silc/local_command.c.
2575 * Added `send_enc_key' and `enc_key_len' fields to the
2576 SilcIDListData structure since they are needed in the re-key
2577 phase. Affected file is silcd/idlist.[ch].

2596 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2597 int64 of at least the xintXX size. If void * is less that 4
2598 bytes uint32 * will be used. Defined bool as boolean.
2600 * Changed _ALL_ unsigned long and unsigned int to uint32,
2601 unsgined short to uint16 in the source tree.
2603 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2604 not handle clients that has entry->data.registered == FALSE.
2605 They are not in the network anymore. Affected file is
2608 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Implemented the sending of the SERVER_SIGNOFF notify in the
2611 server. Affected file is silcd/server.c.
2613 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

2622 implemnted the printing of the SERVER_SIGNOFF info to the
2623 application. Affected file silc/client_ops.c.
2625 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2626 if the deleting was successful. Affected file silcd/idlist.[ch].
2628 * Added support for public key authentication in the connection
2629 authentication protocol in the client library. Affected file
2630 lib/silcclient/protocol.c.
2632 * Changed the server's silc_idlist_get_clients_by_* interface
2633 to support already allocated array so that new entries may be
2634 added to pre-allocated array. Affected file silcd/idlist.[ch].
2635 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2636 and command replies.
2638 * All command reply functions in the server now calls the
2639 pending command callback even if error occured. This way the
2640 error will be delivered to the client as well. Affected files
2641 silcd/command.c and silcd/command_reply.c.
2643 * Fixed INFO command to return local server's info if no server
2644 was provided. Affected file lib/silcclient/command.c.
2646 * Removed RESTART command for good. Updated the code and the

2672 * Added SILC_UMODE_GONE mode to indicate when the client is not
2673 present in the SILC network. Added also support to the local
2674 command AWAY that will set this mode. Added support of showing
2675 "xxx is gone" in WHOIS command. The USERS command shows the
2676 gone status as well.
2678 * Fixed setting server and router operator privileges in the
2679 server's UMODE command. Affected file silcd/command.c.
2681 * Merged the SKE KE1 and KE2 payloads into one payload. The
2682 new KE payload is equivalent to the old KE2 payload.
2684 Cleaned up the SKE Start Payload parsing. It now uses the
2685 simple buffer unformatting to do the parsing. A lot faster
2688 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2689 to the SKE that is used to indicate whether both of the SKE
2690 parties should perform authentication. By default only the
2691 responder performs authentication. By setting this flag also
2692 the initiator must do authentication. By default it is unset
2693 since in normal SKE case, client to server connection, only
2694 the responder should do authentication. When doing SKE between
2695 two clients both should perform authentication. Updated the
2696 code and the protocol specs.
2698 * A little fix to IDENTIFY command in the server. Search the
2699 client first by hash not nickname. Affected file is
2702 * Fixed the silc_client_close_connection to support closing
2703 the client to client connections wihtout deleting too much
2704 data. Affected file lib/silcclient/client.c.
2706 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2707 are received if protocol used to be active but is not anymore
2708 the application would crash due to NULL pointer dereference.
2709 Affected files silcd/server.c and lib/silcclient/client.c.
2711 * Added `hash' field to the SilcClientConnection to include
2712 the hash function negotiated in the SKE protocol.
2714 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2715 to set the channel founder authentication data. A client can
2716 claim the founder rights later by providing the authentication
2717 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2718 This way the channel founder can regain the channel founder
2719 privileges even it is left the channel. This works only on
2720 local server and the client must be connected to the same
2721 server to be able to regain the founder rights. Updated the
2722 protocol specs accordingly.
2724 Added support to the CMODE command in the client to set the
2725 founder auth data. Read the README to see how to set it.
2727 Added support to the CUMODE command to claim the founder
2728 rights. Read the README to see how to do it.
2730 Added support for the founder authentication to the Channel
2731 Entry in the server. Affected file silcd/idlist.h.
2733 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2734 server's CMODE command. Affected file silcd/command.c.
2736 * Added the following new functions into lib/silccore/silcauth.[ch]:
2737 silc_auth_get_method and silc_auth_get_data.
2739 * The server now saves the remote hosts public key to the
2740 SilcIDListData pointer. Affected file silcd/protocol.c.
2742 * The normal server now does not remove the channel entry from
2743 the cache if the founder authentication data is set. It used
2744 to remove it if the founder was the last one on the channel on
2745 the server and left the channel. The auth data is saved and
2746 if the channel is re-joined later the old entry is used with
2747 the old auth data. Affected files silcd/command_reply.c and
2750 * Removed the `pkcs' field from the SilcIDListData structure
2751 in the server; it is not used. Affected file silcd/idlist.h.
2753 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * Fixed packet processing on slow links. Partial packets were
2756 never re-processed because the incoming data buffer was cleared
2757 by the application. Application must not directly clear the
2758 sock->inbuf, the packet processing routines handle it. Fixed
2759 this in client library and in server.
2761 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Fixed the WHOIS and IDENTIFY send reply function to really
2764 check whether to send list or just one entry. Affected file
2767 * Cleaned up the LEAVE command's channel key distribution. The
2768 affected file silcd/command.c.
2770 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2771 can enforce the channel mode as well. In that case the ID
2772 includes the ID of the server. The code now enforces the
2773 mode change if the router have different mode than the server.
2775 * The notify client operation with CMODE_CHANGE notify can now
2776 return NULL client_entry pointer if the CMODE was not changed
2777 by client. Application must check for this.
2779 * Added <Server ID> argument to INFO command to support server
2780 info fetching by Server ID.
2782 * Added silc_server_announce_get_channel_users to get assembled
2783 packets of channel users of the specified channel. Affected
2784 file silcd/server.[ch].
2786 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2787 was freed underneath the ID Cache.
2789 * Re-announce clients when the server received CHANNEL_CHANGE
2790 notify from the router. Affected file silcd/packet_send.c.
2792 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2795 crashed since it did not handle the fact that there is no cipher
2796 called "3" and didn't check the error condition. Now fixed.
2798 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2799 flag. It can be used to send message requests.
2801 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Implemented the RESTART command in the client.
2805 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2806 notice type messages. Added notice printing to the user
2809 * The channel keys are not re-generated if the channel's mode
2810 is PRIVKEY, ie private key on the channel exists. Affected
2811 files silcd/server.c and silcd/command.c.
2813 * Fixed a little bug in channel message delivery when channel
2814 private keys are set in the server. Affected file is
2815 silcd/packet_send.c.
2817 * Changed the setting on channel->on_channel = TRUE from the
2818 silc_client_save_channel_key to the JOIN command reply. The
2819 key payload is not received if the private channel key is set.
2820 Affected file lib/silcclient/command_reply.c and the
2821 lib/silcclient/client_channel.c.
2823 * When the CMODE_CHANGE notify is sent and the channel private
2824 key mode is removed the channel key must be re-generated in
2825 other cells as well. Added this support for the router in the
2826 silcd/packet_receive.c.
2828 * Added new local command NOTICE to send notice message on
2829 channel. Affected file silc/local_command.[ch].
2831 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Added new local command ME to the client. It is used to send
2834 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2835 some action. Affected file silc/local_command.[ch].
2837 * Changed channel_message and private_message client operations
2838 to deliver the message flags to the application. Added also
2839 the `flags' arguments to the silc_client_send_channel_message
2840 and silc_client_send_private_message functions. Affected file
2843 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * Redefined the Private Message Payload to support private message
2846 keys and to support the new private message flags. Updated
2847 the protocol specs. Flags makes it possible to have for example
2848 CTCP style messages.
2850 * Added new type SilcPrivateMessagePayload and defined an API
2851 for it in the lib/silcclient/silcprivate.[ch].
2853 * Tested private message private keys successfully. Tested the
2854 private message key set, unset and list commands with the new
2857 * Redefined the Channel Message Payload to include the channel
2858 message flags (equal with private message flags) to support
2859 for example CTCP style messages.
2861 * Defined some of the message (for channel and private message)
2862 flags. Updated the protocol specs and added the flags to the
2863 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2865 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Added SilcKeyAgreementStatus type to the key agreement routines
2868 to indicate the current status and error if one occured.
2869 The status types are defined in the lib/silcclient/silcapi.h.
2871 * Added new local command KEY that is used to set and unset private
2872 keys for channels, set and unset private keys for private messages
2873 with remote clients and to send key agreement requests and
2874 negotiate the key agreement protocol with remote client. The
2875 key agreement is supported only to negotiate private message keys,
2876 it currently cannot be used to negotiate private keys for channels,
2877 as it is not convenient for that purpose.
2879 * Fixed a minor pending callback setting bug in the function
2880 silc_client_get_client_by_id_resolve, now the function works.
2881 Affected file lib/silcclient/idlist.c.
2883 * Added function silc_net_get_local_port to get local bound
2884 port by socket. Added to lib/silcutil/silcnet.[ch].
2886 * Added `sockets' and `sockets_count' fields to the SilcClient
2887 object. They hold the sockets of the listenning sockets in
2888 the client. Listenning sockets may be for example the key
2889 agreement server. Affected file lib/silcclient/client.[ch].
2890 Added functions the silc_client_add_socket and the
2891 silc_client_del_socket. They are exported to the application
2894 * Added ~./silc/clientkeys to support other client's public keys.
2896 * Renamed verify_server_key client operation to verify_public_key
2897 and added one argument to indicate the type of the connection
2898 (server, client etc.).
2900 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Added silc_server_connection_auth_request to handle the
2903 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2904 silcd/packet_receive.[ch].
2906 * Added silc_server_send_connection_auth_request into the
2907 silcd/packet_send.c to send the connection auth request packet.
2909 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2912 * Fixed the public key authentication in responder side in the
2913 server. The `auth_data' pointer includes the SilcPublicKey
2914 not the path to the public key. Affected file silcd/protocol.c.
2916 * Implemented the public key authentication in the initiator side
2917 in the server. Affected file silcd/protocol.c.
2919 * Removed the [RedirectClient] config section from the server
2920 configuration. Is not needed and I don't want to implement it.
2922 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Cleaned up the CMODE command in the server. It now works
2925 correctly and supports all the modes defined in the protocol.
2926 Affected file is silcd/command.c.
2928 * Added `hmac_name' field to the SilcChannelEntry in the server
2929 to hold the default HMAC of the channel. It can be set when
2930 creating the channel (with JOIN command). Affected files
2933 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2934 type to indicate the change of the current cipher and hmac
2935 on the channel. Client can safely ignore the <cipher> argument
2936 (if it chooses to do so) since the CHANNEL_KEY packet will
2937 force the channel key change anyway. The <hmac> argument is
2938 important since the client is responsible of setting the new
2939 HMAC and the hmac key into use.
2941 * Fixed the CMODE command in the client library as well.
2943 * Tested CMODE command in router environment successfully.
2945 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Show the version of the remote client (or server) when connecting
2948 to the server. It is logged to the log file. Affected file
2949 is silcd/protocol.c.
2951 * Fixed the KILLED notify handling in the client library. The
2952 client must be removed from all channels when receiving the
2955 Also, do not remove the client entry when giving the KILL
2956 command but when the KILLED notify is received.
2958 * Removed silc_idlist_find_client_by_nickname from the server.
2959 Not needed anymore. Affected files silcd/idlist.[ch].
2961 * Implemented the CHANNEL_CHANGE notify type handling to the
2962 server. Affected file silcd/server.c.
2966 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Added silc_server_send_notify_invite to send the INVITE
2969 notify between routers.
2971 * Implemented the INVITE command correctly to the server.
2973 * Implemented the INVITE notify type handling in the server.
2975 * Implemented the INVITE command to the client library and on the
2978 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Added function silc_server_get_client_resolve to find the
2981 client entry by ID from all ID lists and then resolve it
2982 (using WHOIS) if it cannot be found. Affected file is
2985 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Implemented the BAN command to the client library.
2989 * The JOIN command in the server now checks the invite list
2992 * Changed the silc_command_reply_payload_encode_va and the
2993 silc_command_payload_encode_va to support that if argument is
2994 NULL it ignores and checks the next argument. Affected file
2995 lib/silccore/silccommand.c.
2997 * Added silc_server_send_notify_ban to send the BAN notify
2998 type between routers.
3000 * Chaned the silc_notify_payload_encode to support that if
3001 argument is NULL it ignores and checks the next argument.
3002 Affected file lib/silccore/silcnotify.c.
3004 * Tested ban lists in router environment successfully.
3006 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Implemented BAN command to the server, in silcd/command.[ch].
3010 * Removed the BAN and INVITE_LIST modes from the CMODE command
3013 * Added function silc_string_match to regex match two strings.
3014 Affected files lib/silcutil/silcutil.[ch].
3016 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Redefined parts of the SilcChannelEntry in the server to support
3019 the new ban and invite lists.
3021 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Redefined the INVITE command. The same command can be used to
3024 invite individuals to the channel but also to manage the invite
3025 list of the channel (to add to and remove from the invite list).
3026 Updated the protocol specs.
3028 * Added new command SILC_COMMAND_BAN that can be used to manage
3029 the ban list of the channel. Updated the protocol specs.
3031 * Removed the channel modes: the SILC_CMODE_BAN and the
3032 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3033 in the CMODE command. The equivalent features are now available
3034 using INVITE and BAN commands. Updated the protocol specs.
3036 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3037 in the network about change in the current ban list. The notify
3038 type is not used by the client.
3040 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3041 support the invite lists.
3043 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Added new function silc_string_regexify that converts string
3046 including wildcard characters into regex string that can
3047 be used by the GNU regex library. Added into the file
3048 lib/silcutil/silcutil.[ch].
3050 Added silc_string_regex_combine to combine to regex strings
3051 into one so that they can be used as one regex string by
3052 the GNU regex library. Added into the file
3053 lib/silcutil/silcutil.[ch].
3055 Added silc_string_regex_match to match two strings. It returns
3056 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3058 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Imported GNU regex to the soruce tree into lib/contrib.
3061 Fixed some compiler warning from the regex.c.
3063 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Fixed MOTD command in the server to work in router environment.
3067 * Fixed the MOTD command in the client library to support
3068 the server argument in the command.
3070 * Added `nickname_len' argument to the silc_idlist_add_client
3071 in the server, as the `nickname' argument may be binary data
3074 * Added silc_idlist_get_channels to return all channels from
3077 * Implemented LIST command to the server. Affected file is
3080 * Implemented the LIST command to the client library and on the
3083 * Added [<user count>] argument to the LIST command reply.
3084 With private channels the user count is not shown.
3086 * Updated TODO and README.
3088 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * The client entry's data.registered must be TRUE even with
3091 global client entry on global client list. The data.registered
3092 is used to check whether the client is anymore in the network,
3093 for example with WHOWAS command so it must be valid.
3095 * Fixed the WHOWAS command in the server. It now actually works
3096 in router environment. Added function into silcd/command_reply.c
3097 silc_server_command_reply_whowas_save.
3099 * Added silc_idlist_purge function to the silcd/idlist.c
3100 to periodically purge the ID Cache.
3102 * Fixed INFO command in the server. It works now in router
3103 environment. Added <server name> argument to the INFO command
3104 reply. Updated the protocol specs.
3106 * Fixed minor bug in silc_idcache_purge to not purge if the
3107 expire value is zero.

3110 they were buggy because of the WHOWAS information.
3112 * Fixed local command MSG to handle the async resolving of
3113 the remote client properly. It used to fail the first MSG.
3114 Affected file silc/local_command.c.
3116 * Added `data_len' field to SilcIDCache context.
3118 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Update TODO. Todo in commands in the server.
3122 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3125 used by routers as broadcast packet to inform other routers
3126 about the changed user mode.
3128 Implemented the notify handling in the server. Affected file is
3129 silcd/packet_receive.c. Added the function
3130 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3132 * Added new generic Channel Payload and deprecated the New Channel
3133 Payload. The New Channel Payload is now the generic Channel
3136 * Added new argument `mode' to the silc_server_send_new_channel
3137 as it is required in the Channel Payload now.
3139 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3140 and created a new and real SilChannelPayload to represent the
3141 new generic Channel Payload. Implemented the encode/decode
3142 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3144 * Added silc_server_get_client_channel_list to return the list
3145 of channels the client has joined for WHOIS command reply.
3146 Affected file silcd/server.[ch].
3148 * Implemented the channel list sending in the WHOIS command reply
3149 in server and in the client.
3151 Implemented the channel list displaying on the user interface
3152 as well. Affected file silc/client_ops.c.
3154 * Added silc_channel_payload_parse_list to parse list of Channel
3155 Payloads. It returns SilcDList list of SilcChannelPayloads.
3156 Client for example can use this function to parse the list of
3157 channels it receives in the WHOIS command reply. The caller
3158 must free the list by calling silc_channel_payload_list_free.
3159 Affected files lib/silccore/silcchannel.[ch].
3161 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Added one new argument <user mode> to the WHOIS command reply
3164 to return the mode of the user in SILC. Updated the protocol
3167 Implemented it to the server and client.
3169 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Fixed the mode printing on the user interface on joining.
3172 Affected file silc/client_ops.c.
3174 * Implemented the UMODE command and user modes in general to the
3175 client library and to the user interface.
3177 * Implemented the UMODE command to the server.
3179 * The server now sends UNKNOWN_COMMAND error status if client sends
3180 unknown command. Affected file silcd/command.c.
3182 * All server commands now handle the command identifier the right
3183 way when sending the command reply to the client. The client can
3184 use to identify the command replies with the identifier.
3186 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3188 * Added silc_server_get_client_route to resolve the route to
3189 the client indicated by the client ID. Affected file is
3192 * Added silc_server_relay_packet as general function to relay
3193 packet to arbitrary destination. This deprecates functions
3194 like _send_private_message_key, _relay_notify etc. Affected
3195 file is silcd/packet_send.[ch].
3197 Removed silc_server_send_key_agreement,
3198 silc_server_send_private_message_key and
3199 silc_server_packet_relay_notify functions from the file
3200 silcd/packet_send.[ch].
3204 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3205 server. Affected file silcd/packet_receive.[ch].
3207 * Implemented the KILL command to the client. Implemented the
3208 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3209 Affected files lib/silcclient/command[_reply].c and
3210 lib/silcclient/client_notify.c. Implemented the KILL notify
3211 printing in the user inteface.
3213 * Fixed a lot silc_parse_nick memory leaks from the client
3214 library in the file lib/silcclient/command.c.
3216 * Changed the silc_server_send_notify_on_channels's `sender'
3217 argument from SilcSocketConnection to SilcClientEntry to
3218 check the sender as entry and not as connection object and not
3219 to send to the client provided as argument. The affected file
3220 is silcd/packet_send.[ch].
3222 * The notify packets that are destined directly to the client used
3223 to not to be processed by the server. Now changed that and the
3224 server processes all notify packets. After relaying the packet
3225 to the client the notify packet is processed in the server.
3227 * The silc_server_free_client_data now checks whether there is
3228 pending outgoing traffic for the client and purges the data to
3229 the network before removing the client entry.
3231 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3234 an client is killed from the SILC Network. Updated the protocol
3237 Added new function silc_server_send_notify_killed to the
3238 silcd/packet_send.[ch].
3240 * Added function silc_server_packet_relay_notify to relay notify
3241 packets that are destined directly to a client. In this case
3242 the server does not process the notify packets but merely relays
3243 it to the client. Affected file silcd/packet_send.[ch].
3245 Added also silc_server_packet_process_relay_notify to check
3246 whereto relay the notify. Affected file is
3247 silcd/packet_receive.[ch].
3249 * Implemented the KILL command to the server.
3253 * Added the backup schema desgined last fall to the protocol
3254 specs for everyone to see. The specification is in the
3255 *-spec-xx.txt draft and the packet type definitions for the
3256 backup routers is in *-pp-xx.txt draft. Thusly, added also
3257 new packet type SILC_PACKET_CELL_ROUTERS.
3259 * A big security problem in the implementation discovered. The
3260 signoff of an client did not cause new channel key generation
3261 which it of course should've done. The channel keys must be
3262 always re-generated when client leaves (or signoffs) the channel.
3263 The silc_server_remove_from_channels funtion now handles
3264 the channel key re-generation.
3266 * Added `sender' argument to the silc_server_send_notify_on_channels
3267 to not to send the client provided as argument. Affected file
3268 silcd/packet_send.[ch].
3270 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Implemented OPER and SILCOPER commands into the server and
3275 * Added silc_auth_verify and silc_auth_verify_data to verify
3276 the authentication directly from the authentication payload.
3277 It supports verifying both passphrase and public key based
3278 authentication. Affected file lib/silccore/silcauth.[ch].
3280 * Added `hash' field to the SilcIDListData structure. It is the
3281 hash negotiated in the SKE protocol. Affected file is
3284 * Slight redesigning of the SilcAuthPayload handling routines.
3285 Do not send SilcPKCS but SilcPublicKey as argument.
3287 * Implemented the public key authentication support to the
3288 serverconfig. The public key is loaded from the provided path
3289 and saved as authentication data to void * pointer. Thus,
3290 changed the unsigned char *auth_data to void *auth_data;
3292 * Fixed SHUTDOWN command to send the reply before the server
3293 is shutdown. :) Affected file silcd/command.c.
3295 * Fixed fatal bug in CONNECT command. The hostname was invalid
3296 memory and server crashed. Affected file silcd/command.c.
3298 * Fixed fatal bug in CLOSE command. The server_entry became
3299 invalid but was referenced later in the command. Affected file
3302 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Fixed fatal bug in failure packet handling. Server ignored
3305 the failure and thus crashed when it came.
3309 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3312 that the command may be executed only once in (about) 2 seconds.
3313 The old SILC_CF_LAG flag is same but allows command bursts up
3314 to five before limiting.
3316 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3317 server code. Various commands now includes the CF_LAG_STRICT
3318 flag to disallow any kind of miss-use of the command.
3320 * Fixed the silc_buffer_unformat to not to allocate any data
3321 if the length of the data is zero. It used to allocate the
3322 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3324 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Changed the format of AdminConnection configuration section
3327 in the server. Added username of the admin to the format.
3328 Affected files silcd/serverconfig.[ch].
3330 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3331 to return admin configuration data by host, username and/or
3334 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Implemented WHOWAS command to the server. Added the functions:
3338 silc_server_command_whowas_parse,
3339 silc_server_command_whowas_send_reply,
3340 silc_server_command_whowas_from_client and
3341 silc_server_command_whowas_from_server
3343 * Added <Client ID> argument to the WHOWAS command reply. Updated
3344 the protocol specs accordingly.
3346 * Implemented WHOWAS command and command_reply to the client
3349 Implemented the WHOWAS printing on the user interface.
3351 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Added new argument to the WHOWAS command reply, the real name.
3354 It is an optional argument. Updated the protocol specs.
3356 * Added SilcIDCacheDestructor callback that is registered when
3357 the SilcIDCache is allocated. The callback is called when
3358 an cache entry in the ID Cache expires, or is purged from the
3359 cache. Added into lib/silccore/idcache.[ch].
3361 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3362 to destruct the client entries when the cache entry expires.
3363 Other ID Cache's in server and in the client library ignores
3366 * If the ID Cache entry's `expire' field is zero then the entry
3367 never expires. Added boolean `expire' argument to the
3368 silc_idcache_add function in the lib/silccore/idcache.[ch].
3369 If it is TRUE the default expiry value is used.
3371 * Added silc_server_free_client_data_timeout that is registered
3372 when client disconnects. By default for 5 minutes we preserve
3373 the client entry for history - for WHOWAS command.
3375 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Added support to the server to enforce that commands are not
3378 executed more than once in 2 seconds. If server receives
3379 commands from client more frequently, timeout is registered
3380 to process the commands. Affected file silcd/command.c.
3381 Added new function silc_server_command_process_timeout.
3383 * Changed NICK_NOTIFY handling in client library to check that
3384 if the client's nickname was changed, so there is no need to
3385 resolve anything from the server.
3387 * Removed error printing from the WHOIS and IDENTIFY commands.
3388 If error occurs then it is ignored silently in the client library.
3389 The application, however, may map the received error to
3390 human readable error string. The application currently maps
3391 the NO_SUCH_NICKNAME error to string.
3393 * Made the command status message public to the application. Moved
3394 them from lib/silcclient/command_reply.c to
3395 lib/silcclient/command_reply.h. The application can map the
3396 received command status to the string with the
3397 silc_client_command_status_message function.
3399 * Added check to the server to check that client's ID is same
3400 as the Source ID in the packet the client sent. They must
3403 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Added dist-bzip hook to the Makefile.am to make bzip2
3406 compressed distributions.
3408 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Server now enforces the maximum length for the nickname and
3411 the channel as protocol specification dictates. 128 bytes for
3412 nickname and 256 bytes for channel name.
3414 * Moved the WHOIS printing to the application. The client libary
3415 does not print out the WHOIS information anymore, the application
3416 must do it. Renamed silc_client_command_reply_whois_print to
3417 the silc_client_command_reply_whois_save.
3419 The client's idle time is also sent to the application now, and
3420 the idle is shown on screen.
3422 * Added silc_client_command_reply_identify_save to save the
3423 received IDENTIFY entries.
3425 * Do not check for channel private keys in message sending and
3426 reception if the channel does not have the PRIVKEY mode set.
3427 Affected file lib/silclient/client_channel.c.
3429 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3432 just surfaced after chaning the JOIN procedure.
3434 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added silc_client_get_clients_by_list to get client entries
3437 from Client ID list, that is returned for example by JOIN
3438 and USERS command replies. The application should use this
3439 function for example when JOIN command reply is received to
3440 resolve the clients already on the channel (library does not
3441 do that anymore as USERS command reply is not used in the JOIN
3442 procedure anymore). Affected files lib/silcclient/silcapi.h and
3443 lib/silcclient/idlist.c.
3445 * JOIN command reply and USERS command reply returns now SilcBuffer
3446 pointers instead of unsigned char pointers when returning
3447 the client list and mode list.
3449 * Added <Client ID> argument to the JOIN command reply, mainly
3450 for the server to identify for which client the command was
3451 originally sent. Updated protocol specs accordingly.
3453 * Added SilcDlist private_key pointer to the SilcChannelEntry
3454 in the client to support the channel private keys. Affected
3455 file is lib/silcclient/idlist.h.
3457 * Added SilcChannelPrivateKey argument to the function
3458 silc_client_send_channel_message so that application can choose
3459 to use specific private ke if it wants to. If it is not provided,
3460 the normal channel key is used, unless private keys are set.
3461 In this case the first (key that was added first) is used
3462 as the encryption key.
3464 * Implemented the support for channel private key handling.
3465 Implemented the following functions:
3467 silc_client_add_channel_private_key,
3468 silc_client_del_channel_private_keys,
3469 silc_client_del_channel_private_key,
3470 silc_client_list_channel_private_keys and
3471 silc_client_free_channel_private_keys
3473 Affected file lib/silcclient/client_channel.c.
3475 * Added the support for the private keys in the channel message
3476 sending and encryption and in the message reception and
3477 decryption. Affected funtions are
3478 silc_client_send_channel_message and silc_client_channel_message.
3480 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Added SKE's key verify callback to the client library's
3483 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3485 * Removed the statement that server (or router) must send USERS
3486 command reply when joining to the channel so that the client
3487 knows who are on the channel. Instead, the client list and
3488 client's mode list is now sent in the JOIN command reply to the
3489 client who joined channel. This is better solution.
3491 * Added function silc_server_get_users_on_channel and function
3492 silc_server_save_users_on_channel to the silcd/server.[ch].
3494 * Removed function silc_server_command_send_users from the
3497 * Do not show topic on the client library anymore. The topic is
3498 sent in the command reply notify to the application and the
3499 application must show the topic now.
3501 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added client searching by nickname hash into the IDENTIFY and
3504 WHOIS commands in the server as they were clearly missing from
3505 them. Affected file is silcd/command.c.
3507 * Fixed a bug in private message receiving in the client library.
3508 The remote ID was freed and it wasn't supposed, now it is
3511 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Minor fix to the channel payload; allocate the data area, as it
3514 needs to be of specific length.
3516 * If the key agreement port is zero then the operating
3517 system will define the bound port. Affected files are
3518 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3520 * Added new function silc_channel_payload_decrypt into the file
3521 lib/silccore/silcchannel.[ch].
3523 * Moved the channel message etc, check from silc_packet_decrypt
3524 to applications. The library calls now a generic
3525 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3526 when the packet is either normal or special. This was done to
3527 allow more wide range of checking that was not allowed when
3528 the code was in library. Now applications can do virtually any
3529 checks to the packet and return to the library the decision how
3530 the packet should be processed. Affected files are
3531 lib/silccore/silcpacket.[ch].
3533 Added silc_server_packet_decrypt_check to the server and
3534 silc_client_packet_decrypt_check to the client library.
3536 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3537 to send with specified source and destination information.
3539 * Channel message delivery between routers was broken after the
3540 channel key distribution was fixed earlier. The channel key
3541 was used be to distributed to other routers as well which is not
3542 allowed by the protocol. Now this is fixed and channel keys
3543 really are cell specific and the channel message delivery between
3544 routers comply with the protocol specification.
3546 * Fixed various commands in server to check also the global list
3547 for the channel entry and not just the local list. The affected
3548 file silcd/command.c.
3550 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Added assert()s to buffer formatting and unformatting routines
3553 to assert (if --enable-debug) when error occurs. Affected
3554 file: lib/silcutil/silcbuffmt.c.
3556 * Changed to auto-reconnect to check whether the remote host is
3557 router and register the re-connect timeout if it is. It used
3558 to check that whether we are normal server, but router must do
3559 auto-reconnect with another router as well. Affected file
3562 * Removed the [<key len>] option from CMODE command as the cipher
3563 name decides the key length, nowadays. See the defined ciphers
3564 from the protocol specification.
3566 * Added [<hmac>] option to the CMODE command to define the HMAC
3567 for the channel. Added SILC_CMODE_HMAC channel mode.
3569 * Added [<hmac>] option for the JOIN command so that user can
3570 select which HMAC is used to compute the MACs of the channel
3573 * Added Hmac field to the Channel Message Payload. The integrity
3574 of plaintext channel messages are now protected by computing
3575 MAC of the message and attaching the MAC to the payload. The
3576 MAC is encrypted. Now, it is clear that this causes some
3577 overhead to the size of the packet but rationale for this is that
3578 now the receiver can verify whether the channel message decrypted
3579 correctly and also when private keys are set for the channel the
3580 receiver can decrypt the packet with several keys and check from
3581 the MAC which key decrypted the message correctly.
3583 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3584 lib/silccrypt/silccipher.[ch].
3586 * Added silc_hash_len to return the digest length into the
3587 lib/silcrypt/silchash.[ch].
3589 * Rewrote parts of Silc Channel Payload interface in the
3590 lib/silccore/silcchannel.[ch]. The encode function now also
3591 encrypts the packet and parse function decrypts it.
3593 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Fixed a minor formatting bug in the SKE's key material processing.
3596 It actually might have processed the keys wrong way resulting
3599 * Redefined the mandatory HMAC algorithms and added new algorithms.
3600 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3601 and hmac-md5 truncated to 96 bits. The mandatory is now
3602 hmac-sha1-96. Rest are optional (including the one that used
3603 to be mandatory). Rationale for this is that the truncated HMAC
3604 length is sufficient from security point of view and can actually
3605 make the attack against the HMAC harder. Also, the truncated
3606 HMAC causes less overhead to the packets. See the RFC2104 for
3609 * Added new [hmac] configuration section. The SKE used to use
3610 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3611 is of course wrong. The official names that must be proposed in
3612 the SKE are the ones defined in the protocol specification
3613 (hmac-sha1-96 for example). The user can configure any hmac
3614 using any hash function configured in the [hash] section. At
3615 least, the mandatory must be configured.
3617 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3619 * Added HMAC list to the SKE proposal list. It has now both
3620 hash algorithm list and HMAC list. This makes the protocol
3621 incompatible with previous versions. The SKE now seems to work
3622 the way it is supposed to work, for the first time actually.
3624 * Defined plain Hash algorithms to the protocol specification.
3627 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Implemented support for key agreement packets into the server.
3630 Added functions silc_server_key_agreement and
3631 silc_server_send_key_agreement. Other than these functions,
3632 server has nothing to do with this packet.
3634 * Added support for private message key packets into the server.
3635 Added functions silc_server_private_message_key and
3636 silc_server_send_private_message_key.
3640 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3641 called in the protocol's final callback instead in the END
3642 protocol state. This makes a little more sense and in the same
3643 time in client we can use the same protocol routines for normal
3644 key exchange and to key agreement packet handling as well.
3646 * Added to both client's and server's KE protocol context the
3647 SilcSKEKeyMaterial pointer to save the key material. We will
3648 bring the key material to the protocol's final callback by doing
3649 this. The final callback must free the key material.
3651 * Added SKE's packet_send callback into client's KE protocol
3652 context so that the caller can choose what packet sending function
3653 is used. This way we can use different packet sending when
3654 doing normal SKE when doing key agreement packet handling (in
3655 the key agreement packet handling we do not want to encrypt
3658 * Implemented the responder side of the key agreement routines
3659 in the client. The client can now bind to specified port and
3660 accept incoming key negotiation. The key material is passed
3661 to the application after the protocol is over.
3663 * Implemented the processing of incoming Key Agreement packet
3664 in the client. Added function silc_client_key_agreement to
3667 * Implemented the intiator side of the key agreement routines
3668 in the client. The client can now initiate key agreement with
3669 another remote client. The key material is passed to the
3670 application after the protocol is over.
3672 * Created client_keyagr.c to include all the key agreement
3675 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3676 SILC_TASK_CALLBACK except that it is not static.
3678 * Created client_notify.c and moved the Notify packet handling
3679 from the client.[ch] into that file.
3681 * Created client_prvmsg.c and moved all private message and
3682 private message key routines from the client.[ch] into that file.
3684 * Create client_channel.c and moved all channel message and
3685 channel private key routines from the client.[ch] into that file.
3687 * Changed silc_client_get_client_by_id_resolve to resolve with
3688 WHOIS command instead of IDENTIFY command, in the file
3689 lib/silclient/idlist.c.
3691 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Implemented the SKE's responder side to the Client library.
3695 * When FAILURE is received to the protocol do not trust it
3696 blindly. Register a timeout to wait whether the remote closes
3697 the connection as it should do it, only after that process the
3698 actual failure. This was changed to both client and server.
3700 * Added client_internal.h to include some of the structures
3701 there instead of client.h in lib/silcclient/.
3703 * Added function silc_task_unregister_by_callback to unregister
3704 timeouts by the callback function.
3706 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Some "Incomplete WHOIS info" errors has been appearing on the
3709 log files. Took away the entry->userinfo check from WHOIS
3710 reply sending. The entry->userinfo is now " " if client did not
3711 provide one. I thought this was fixed earlier but something
3712 is wrong still. Let's see if the error still appears.
3714 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed a minor bug in the login when the channel key is
3717 re-generated in the server. It used to generate the key in
3718 wrong order and thus caused problems in the channel traffic.
3720 * Fixed a minor bug in channel key distsribution after
3721 KICK command. The key was not sent to the router even though
3724 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added silc_ske_process_key_material_data as generic routine
3727 to process any key material as the SILC protocol dictates. The
3728 function is used by the actual SKE library but can be used by
3729 applications as well. This relates to the private message keys
3730 and the channel private keys since they must be processed the
3731 same way the normal SILC session keys. The protocol dictates
3732 this. Affected files: lib/silcske/silcske.[ch].
3734 Added also silc_ske_free_key_material to free the
3735 SilcSKEKeyMaterial structure.
3737 * Defined silc_cipher_set_key function to set the key for
3738 cipher without using the object's method function. The affected
3739 files: lib/silccrypt/silccipher.[ch].
3741 * Implemented silc silc_client_add_private_message_key,
3742 silc_client_add_private_message_key_ske,
3743 silc_client_del_private_message_key,
3744 silc_client_list_private_message_keys and
3745 silc_client_free_private_message_keys functions in the
3748 Added functions silc_client_send_private_message_key to send
3749 the Private Message Key payload and silc_client_private_message_key
3750 to handle incoming Private Message Key payload.
3752 * Added Cipher field to the Private Message Key payload to set
3753 the cipher to be used. If ignored, the default cipher defined
3754 in the SILC protocol (aes-256-cbc) is used.
3756 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Removed lib/silcclient/ops.h file.
3760 Redefined parts of the SILC Client Library API. Created new
3761 file silcapi.h that deprecates the ops.h file and defines the
3762 published Client Library API. Defined also private message key
3763 API and channel private key API into the file.
3765 This is the file that the application must include from the
3766 SILC Client Library. Other files need not be included by
3767 the application anymore.
3769 * Added new key_agreement client operation callback and also
3770 defined the Key Agreement library API for the application.
3772 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3775 is used by clients to request key negotiation between another
3776 client in the SILC network. If the negotiation is started it
3777 is performed using the SKE protocol. The result of the
3778 negotiation, the secret key material, can be used for example
3779 as private message key.
3781 Implemented the Key Agreement payload into the files
3782 lib/silccore/silauth.[ch].
3784 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Redefined ciphers for the SILC protocol. Added some new ciphers
3787 and defined the key lengths for the algorithms. Changed the
3788 code accordingly. The default key length is now 256 bits.
3790 * Fixed SKE key distribution function silc_ske_process_key_material
3791 when the key length is more than 128 bits. The default key
3792 length in SILC is now 256 bits.
3794 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3795 to indicate unsupported algorithm.
3797 * Renamed rijndael.c to aes.c and all functions as well.
3799 * Fixed a long standing channel key setting bug in client library.
3800 Weird that it has never surfaced before.
3802 * Fixed bug in channel deletion. If the entire channel is removed
3803 then it must also delete the references of the channel entry
3804 from the client's channel list as the client's channel entry and
3805 the channel's client entry share same memory.
3807 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Implemented CONNECT and SHUTDOWN commands in the client.
3811 * Implemented CLOSE command to the client.
3813 * Added the function silc_idlist_find_server_by_name into the
3814 files silcd/idlist.[ch].
3816 Added the function silc_idlist_find_server_by_conn into the
3817 files silcd/idlist.[ch].
3819 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * DIE command was renamed to SHUTDOWN. Updated the both code
3824 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3825 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3827 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3830 * Added function silc_server_create_connection function to create
3831 connection to remote router. My server implementation actually
3832 does not allow router to connect to normal server (it expects
3833 that normal server always initiates the connection to the router)
3834 so the CONNECT command is only good for connecting to another
3837 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3840 or some other client was kicked from the channel.
3842 Implemented the handling of the notify type to both client
3845 Implemented silc_server_send_notify_kicked to send the KICKED
3846 notify. It is used to send it to the server's primary router.
3848 * Implemented the KICK command into server and client.
3850 * Added `query' argument to the silc_idlist_get_client function
3851 to indicate whether to query the client from server or not if
3854 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3855 to indicate that the client is not channel founder.
3859 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Removed the rng context from SilcPacketContext structure and
3862 changed that the packet routine uses the Global RNG API.
3864 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Added support for quit message that client can "leave" on the
3867 channel when it quits the SILC. It is ditributed inside the
3868 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3870 Added silc_server_free_client_data that will take the
3871 signoff message as argument.
3873 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3875 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Updated parts of the protocol specification to keep it up
3880 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3883 payloads in one packet.
3885 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3886 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3887 use now the new List flag.
3889 * Also deprecated the following packet types: REPLACE_ID,
3890 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3892 * Added list support for Notify packet in server.
3894 * Added silc_server_send_notify_channel_change to send the
3895 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3896 the silc_server_send_replace_id.
3898 * Added silc_server_send_notify_nick_change to send the
3899 NICK_CHANGE notify type. Deprecates the function
3900 silc_server_send_replace_id.
3902 * Added silc_server_send_notify_join to send the JOIN notify type.
3903 Deprecates the function silc_server_send_new_channel_user.
3905 * Added silc_server_send_notify_leave to send LEAVE notify type.
3906 Deprecates the function silc_server_send_remove_channel_user.
3908 * Added silc_server_send_notify_cmode and
3909 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3910 types. Deprecates the silc_server_send_set_mode function.
3912 * Added SERVER_SIGNOFF notify type to indicate that server has
3913 quit. This means that all clients on the channel from that
3914 server will drop. This can be also used when netsplit happens.
3916 Deprecated REMOVE_ID packet type since it is not needed anymore
3919 Added silc_server_send_notify_server_signoff to send the
3920 SERVER_SIGNOFF notify type. Deprecates the function
3921 silc_server_send_remove_id.
3923 Added also silc_server_send_notify_signoff to send the
3924 SIGNOFF notify type.
3926 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3927 SILC protocol from this day on. Changed the protocol
3928 specification as well.
3930 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3931 notify type. It is used between routers to notify about
3932 topic changes on a channel.
3934 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3937 * Partly updated the protocol specification to comply with the
3938 changes now made. It is still though a bit outdated.
3940 * The JOIN notify type now takes one extra argument <Channel ID>.
3941 The packet used to be destined to the channel but now the
3942 JOIN type may be sent as list thus it is impossible to
3943 destine it to any specific channel. By adding this argument
3944 it is again possible.
3946 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added CREDITS file. The CHANGES and CREDITS file will appear
3949 in the distribution as well.
3951 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3954 types in the server's silcd/packet_receive.c.
3956 * Implemented CMODE and CUMODE to work in router environment.
3958 * Fixed minor encoding and decoding buglet from the
3959 lib/silccore/silcmode.c.
3961 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3964 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3966 * Changed all SilcConfigServer* and silc_config_server* to
3967 SilcServerConfig* and silc_server_config*, respectively.
3970 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Associated the ID (client or server ID) to the Authentication
3973 Payload to avoid any possibility of forging. Updated the
3974 protocol specification and the code accordingly.
3976 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * The RSA key length is now save to the RsaKey context in the
3979 key generation process in lib/silccrypt/rsa.c. The key length
3980 is now used to figure out the maximum size of the block allowed
3981 to be encrypted/signed.
3983 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3984 is equivalent to the silc_mp_mp2bin but does not allocate any
3987 * Changed silc_mp_mp2bin API to take length argument. If it is
3988 non-zero then the buffer is allocated that large. If zero, then
3989 the size is approximated using silc_mp_sizeinbase, which however
3992 * Created Global RNG API which is global RNG that application can
3993 initialize. After initializing, any routine anywhere in the
3994 code (including library) can use RNG without allocating a new
3995 RNG object. This was done to allow this sort of use of the
3996 RNG in code that has no chance to allocate RNG object. All
3997 applications currently allocate this and many routines in the
3998 library use this. Affected file lib/silccrypt/silcrng.[ch].
4000 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4001 it to use the Global RNG API.
4003 * Defined Authentication Payload into protocol specification that
4004 is used during SILC session to authenticate entities. It is
4005 used for example by client to authenticate itself to the server
4006 to obtain server operator privileges.
4008 Implemented this payload into the lib/silccore/silcauth.[ch].
4009 Implemented also routines for public key based authentication
4010 as the new protocol specification dictates.
4012 Moved definitions of different authentication methods from
4013 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4015 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4016 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4017 silc_pkcs_verify_with_hash functions into the file
4018 lib/silccrypt/silcpkcs.[ch].
4020 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * The client entry's userinfo pointer must be always valid.
4023 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4024 will fail since it requires the userinfo. Now, the userinfo
4025 is allocated as "" if actual userinfo does not exist. Actually,
4026 it must exist and it is totally Ok to drop client connections
4027 that does not announce the userinfo. However, we will make
4028 this workaround for now.
4030 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4031 to return the remote port by socket.
4033 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4036 SILC_SERVER_PENDING_EXEC and added an new macro
4037 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4038 data or when error occurs while processing the pending command.
4040 Added new argument `destructor' into silc_server_command_pending
4041 and to the SilcServerCommandPending object. This destructor is
4042 now called after calling the pending callback or if error occurs
4043 immediately. If error occurs the actual pending callback won't
4044 be called at all - only the destructor. The destructor may be
4045 NULL if destructor is not needed.
4047 All this applies for client library code as well. Similar
4048 changes were made there as well for the pending commands.
4050 In the client, the application must now allocate the
4051 SilcClientCommandContext with the silc_client_command_alloc
4054 * Added reference counter to the SilcServerCommandContext. Added
4055 function silc_server_command_alloc and silc_server_command_dup
4058 Same type of functions added to the client library for the same
4061 * Removed the cmd_ident from IDListData away since it is now
4062 global for all connections. It is the command identifier used
4063 in command sending and with pending commands. The affected file
4066 * Added reference counter to the SilcSocketConnection objecet to
4067 indicate the usage count of the object. The object won't be
4068 freed untill the reference counter hits zero. Currently only
4069 server uses this, and client ignores it. The client must be
4070 set to use this too later. The affected files are
4071 lib/silccore/silcsockconn.[ch]. Added also the function
4072 silc_socket_dup to increase the reference counter.
4074 This was mainly added because it is possible that the socket
4075 is removed underneath of pending command or other async
4076 operation. Now it won't be free'd and proper DISCONNECTING
4077 flags, etc. can be set to avoid sending data to connection that
4078 is not valid anymore.
4080 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4081 the connection. After that it sets SILC_SET_DISCONNECTED.
4082 It is, however, possible that the socket data is not still freed.
4083 The silc_server_packet_process now checks that data is not
4084 read or written to connection that is DISCONNECTED. The socket
4085 get's freed when the reference counter hits zero.
4087 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Changed the client operation API: channel_message operation's
4090 `sender' is now the client entry of the sender, not the nickname
4091 and the `channel' is the channel entry, not the channel name.
4093 In the private_message operation the `sender' is now also the
4094 client entry of the sender not the nickname.
4096 Affected file is lib/silcclient/ops.h and all applications
4097 using the client operations.
4099 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Moved the calling of ops->connect() from connect_to_server_final
4102 into receive_new_id functin since that is the point when the
4103 client is actually allowed to send traffic to network. The
4104 affected file is lib/silcclient/client.c.
4106 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4109 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4110 (if needs broadcasting) instead of broadcasting the packets one
4111 by one which would make a burst in the network traffic.
4113 * Added `broadcast' argument to the functions in silcd/server.[ch]
4114 silc_server_create_new_channel[_with_id] to indicate whether
4115 to send New Channel packet to primary router.
4117 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Added new function into the silcd/server.[ch] files:
4120 silc_server_create_new_channel_with_id to create new channel with
4121 already existing Channel ID.
4123 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4124 lib/silccore/silcpacket.h. This packet is used t send list of
4125 Set Mode payloads inside one packet. Server uses this to set
4126 the modes for the channels and clients on those channels, that it
4127 announced to the router when it connected to it. The protocol
4128 specification has been updated accordingly.
4130 * The silc_server_new_channel did not handle the packet coming
4131 from normal server as it normally does not send that. However,
4132 when it announces its channels it does send it. Implemented
4133 the support for that.
4135 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4136 into the file lib/silccore/id.h.
4138 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Fixed memory leaks in the functions silc_idlist_del_client,
4141 silc_idlist_del_channel and silc_idlist_del_server in the file
4142 silcd/idlist.c. All of those leaked like a sieve.
4144 * Fixed some small memory leaks in the client's function
4145 silc_client_notify_by_server.
4147 * Added functions into silcd/server.c: silc_server_announce_clients,
4148 silc_server_announce_channels and silc_server_announce_server.
4149 These functions are used by normal and router server to announce
4150 to its primary router about clients, channels and servers (when
4151 router) that we own. This is done after we've connected to the
4154 These functions effectively implements the following packet types:
4155 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4156 and SILC_PACKET_NEW_ID_LIST.
4158 * Added new functions into the silcd/packet_receive.[ch]:
4159 silc_server_new_id_list, silc_server_new_channel_list and
4160 silc_server_new_channel_user_list to handle the incoming
4161 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4163 * Added support of changing Channel ID in the function
4164 silc_server_replace_id. If the server that announces a channel
4165 to the router already exists in the router (with same name but
4166 with different Channel ID), router is responsible to send
4167 Replace ID packet to the server and force the server to change
4168 the Channel ID to the one router has.
4170 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4171 client that the Channel ID has been changed by the router. The
4172 normal server sends this to the client. Client must start using
4173 the new Channel ID as the channel's ID.
4175 Implemented handling of this new type into lib/silcclient/client.c
4176 into the function silc_client_notify_by_server.
4178 * Added new function silc_idlist_replace_channel_id into the files
4179 silcd/idlist.[ch] to replace the Channel ID.
4181 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Call silc_server_command_identify_check always when processing
4184 the IDENTIFY command in silcd/command.c
4186 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4189 send keepalive packets. The packet can be sent by clients,
4190 servers and routers.
4192 Added function silc_socket_set_heartbeat into the file
4193 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4194 If not set, the heartbeat is not performed. The actual
4195 heartbeat is implemented in the low level socket connection
4196 library. However, application is responsible of actually
4199 Added silc_server_send_heartbeat to send the actual heartbeat
4200 packet into silcd/packet_send.[ch]. Server now performs
4201 keepalive with all connections.
4203 * Added silc_task_get_first function into lib/silcutil/silctask.c
4204 to return the timeout task with shortest timeout. There was a bug
4205 in task unregistration that caused problems. TODO has been
4206 updated to include that task system must be rewritten.
4208 * The client library will now resolve the client information when
4209 receiving JOIN notify from server for client that we know but
4210 have incomplete information.
4212 * Rewrote parts of silc_server_remove_from_channels and
4213 silc_server_remove_from_one_channel as they did not remove the
4214 channel in some circumstances even though they should've.
4216 * Encryption problem encountered in server:
4218 The LEAVE command used to send the Channel Key packet to the
4219 router immediately after generating it. However, the code
4220 had earlier sent Remove Channel user packet but not immediately,
4221 ie. it was put to queue. The order of packets in the router
4222 was that Channel Key packet was first and Remove Channel User
4223 packet was second, even though they were encrypted in the
4224 reverse order. For this reason, MAC check failed. Now, this
4225 is fixed by not sending the Channel Key packet immediately but
4226 putting it to queue. However, this is more fundamental problem:
4227 packets that are in queue should actually not be encrypted
4228 because packets that are sent immediately gets encrypted
4229 actually with wrong IV (and thus MAC check fails). So, packets
4230 that are in queue should be encrypted when they are sent to
4231 the wire and not when they put to the queue.
4233 However, the problem is that the current system has not been
4234 designed to work that way. Instead, the packet is encrypted
4235 as soon as possible and left to the queue. The queue is then
4236 just purged into wire. There won't be any fixes for this
4237 any time soon. So, the current semantic for packet sending
4240 o If you send packet to remote host and do not force the send
4241 (the packet will be in queue) then all subsequent packets to the
4242 same remote host must also be put to the queue. Only after the
4243 queue has been purged is it safe again to force the packet
4246 o If you send all packets immediately then it safe to send
4247 any of subsequent packets through the queue, however, after
4248 the first packet is put to queue then any subsequent packets
4249 must also be put to the queue.
4251 Follow these rules and everything works fine.
4253 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Added new function silc_server_remove_clients_by_server to
4256 remove all client entries from ID list when the server connection
4257 is lost. In this case it is also important to invalidate all
4258 client entires as they hold the invalid server entry. This
4259 fixes fatal bug when server has lost connection and will reconnect
4262 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Made some sanity checks to silc_server_daemonise like to check
4265 whether the requested user and group actually exists.
4267 * Added sanity check to SKE's silc_ske_responder_finish to check
4268 that the public and private key actually is valid.
4270 * Invalidate the client's nickname when receiving Replace ID
4271 packet and the Client ID is being replaced. This means that the
4272 server will query the nickname if someone needs it (client)
4275 * Sort the ID Cache in client library when the ID Cache data
4276 has changed (needs sorting).
4278 * Do not allow for SILC client to create several connections to
4279 several servers. The client does not support windows right now
4280 and generating multiple connections causes weird behaviour.
4282 Irssi-silc client does support windows and can handle several
4283 connections without problems, see: www.irssi.org and SILC plugin.
4285 * Fixed some places where client was added to the IDList. The
4286 rule of thumb is following (in order to get everything right):
4287 If the client is directly connected local client then the
4288 `connection' argument must be set and `router' argument must be
4289 NULL to silc_idlist_add_client function. If the client is not
4290 directly connected client then the `router' argument must
4291 bet set and the `connection' argument must be NULL to the
4292 silc_idlist_add_client function.
4294 * The funtion silc_server_packet_send_local_channel actually did
4295 not check whether the client was locally connected or not. It
4296 does that now. Fixed a bug related to LEAVE command.
4298 * Fixed Remove Channel User payload parsing bug in server's
4299 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4301 * The server's silc_server_save_channel_key now checks also the
4302 global ID list for the channel as it might not be in the local
4303 list. Fixed a bug related to LEAVE command.
4305 * Is this the end of the [<unknown>] buglet that has been lurking
4306 around for a long time? A little for loop fix in server's
4307 silc_server_command_whois_parse that is used by both IDENTIFY
4308 and WHOIS command. At least, this was a clear bug and a cause
4309 of one type of [<unknown>] buglet.
4311 * WHOIS and IDENTIFY commands call the function
4312 silc_server_command_[whois/identify]_check function even if
4313 we are not router server.
4315 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Added --with-gmp configuration option. If set the GMP
4318 is always compiled in the SILC source tree. If not set then
4319 it is checked whether the system has the GMP3 installed. If
4320 it has then the GMP won't be compiled (the system's headers
4321 and library is used), if it doesn't have it then the GMP is
4322 compiled in the SILC source tree.
4324 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Changed RSA private exponent generation to what PKCS #1
4327 suggests. We try to find the smallest possible d by doing
4328 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4329 not security fix but optimization.
4331 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added new config entry [Identity] to fork the server and run
4334 it as specific user and group. A patch from Bostik.
4336 * Imported Dotconf configuration library into lib/dotconf.
4337 This will be used to create the SILC configuration files later.
4338 It will appear in the distsribution after this commit.
4340 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * A big code auditing weekend happening. Auditing code for
4343 obvious mistakes, bugs and errors. Also, removing any code
4346 Removed files for being obsolete:
4348 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4349 inline in the file lib/silcutil/silcbuffer.h)
4351 o lib/silcutil/silcbufutil.c (the header has inline versions)
4353 Changed code to fix possible error conditions:
4355 o The buffer formatting routines now check that the destination
4356 buffer really has enough space to add the data. This applies for
4357 both buffer formatting and unformatting
4358 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4359 unformatting was changed to accomodate following rules:
4360 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4361 sent to the function while XXX_*STRING will not allocate or copy
4362 the data into the buffer. Instead it sets the pointer from the
4363 buffer into the pointer sent as argument (XXX_*STRING used to
4364 require that the pointer must be allocated already). This change
4365 makes this whole thing a bit more consistent and more optimized
4366 (note that the data returned in the unformatting with XXX_*STRING
4367 must not be freed now). The routines return now -1 on error.
4369 o Tried to find all code that use buffer_format and buffer_unformat
4370 and added return value checking to prevent formatting and
4371 especially unformatting errors and possible subsequent fatal
4374 o Changed ske->x and ske->KEY to mallocated pointers in
4375 lib/silcske/silcske.h. Fixed possible data and memory leak.
4377 o Added return value checking to all *_parse* functions. Fixed
4378 many memory leaks as well.
4380 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4381 so that buffer overflows would not happen. All code now also
4382 checks the return value as it can fail.
4384 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Added reconnection support to server if the normal server looses
4387 its connection to the router (for example if router is rebooted).
4388 The server performs normal reconnection strategy implemented
4389 to the server. Affected file silcd/server.c.
4391 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added new packet type SILC_PACKET_SET_MODE that is used to
4394 distribute the information about changed modes (for clients,
4395 channels and clients channel modes) to all routers in the
4396 network. Updated the protocol specification accordingly.
4398 Added functions into silcd/packet_send.c and
4399 silcd/packet_receive.c: silc_server_send_set_mode,
4400 silc_server_set_mode.
4402 Added new files silcmode.[ch] into lib/silccore that implements
4403 the encoding and decoding of Set Mode Payload. Added new type
4404 SilcSetModePayload. Moved the definitions of different modes
4405 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4407 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Oops, a little mistake in server's connection authentication
4410 protocol. The protocol is not ended with FAILURE but with
4411 SUCCESS if the authentication is Ok. :) Affected file is
4414 * Implemented NICK_CHANGE notify handling in server in the file
4415 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4416 the local clients on the channel. After the changing nickname
4417 in router environment snhould work and the [<unknown>] nickname
4418 should appear no more.
4420 The silc_server_replace_id function that receives the Replace ID
4421 payload now sends the NICK_CHANGE notify type also in the file
4422 silcd/packet_receive.c
4424 * Changed WHOIS and IDENTIFY command to support the maximum amount
4425 of arguments defined in protocol specs (3328 arguments). This
4426 fixed a bug that caused problems when there were more than three
4429 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added extra parameter, command identifier, to the
4432 silc_client_send_command so that explicit command identifier
4435 Changed that ID list routines uses specific command identifier
4436 when sending WHOIS/IDENTIFY requests to the server so that they
4437 can be identified when the reply comes back.
4439 Affected files lib/silcclient/command.[ch],
4440 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4442 * Added `sender' argument to silc_server_packet_send_to_channel
4443 to indicaet the sender who originally sent the packet to us
4444 that we are now re-sending. Ignored if NULL. Affected file
4445 silcd/packet_send.[ch].
4447 * Added some server statistics support in silcd/server_internal.h
4448 SilcServerStatistics structure and around the server code. Also
4449 send some nice statistics information when client is connecting
4452 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Fixed channel ID decoding in server's JOIN command reply in
4455 silcd/command_reply.c
4457 * Fixed braodcasting of replace ID payload to not to send it if
4458 we are standalone server in silcd/packet_receive.c.
4460 * Fixed all channel message sending routines to not to send
4461 packets to clients that has router set, since they are routed
4462 separately in the same function earlier. Affects file
4463 silcd/packet_send.c and all channel packet sending functions.
4465 * In USERS reply, res_argv[i] are not allocated, the table
4466 is allocated. Thus changed that free the table, not its
4469 * In server's whois_check and identify_check if the client is
4470 locally connected do not send any WHOIS commands - they are not
4473 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Fixed some minor bugs in client when sending WHOIS command. The
4476 arguments was in wrong order.
4478 * Removed statis function add_to_channel from server in
4479 silcd/command.c that was previously used with the joining but
4482 * Tested USERS command in router environment successfully with two
4483 routers, two servers and two clients.
4485 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Reorganized the USERS command and command reply in client library
4488 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4489 When the command is given by user we register a pending command
4490 callback that will reprocess the command after the reply has been
4491 received from the server. When reprocessing the packet we then
4492 display the information. Thus, the USERS information is displayed
4493 now in the command callback instead of in the command reply
4494 callback. The processing of the command is same as previously
4495 when server has sent the command reply in the JOINing process.
4497 * Added to USERS command in silcd/command_reply.c to join the client,
4498 we didn't use to know about, to the channel after we've created
4499 a client entry for it. Also, for clienet we did know already still
4500 check whether it is on the channel or not and add it if not.
4502 * Removed silc_server_command_join_notify as the function and its
4505 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Changed the client's pending command handling to the same as the
4508 server's pending command handling. It is also now possible to
4509 execute command reply functions from other command reply
4510 function as the function callbacks for commands and command
4511 replies are one and same. The pending commands are not static
4512 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4513 in client connection context. Thus, pending commands are server
4514 connection specific as it is convenient.
4516 Changed the function silc_client_command_pending and
4517 silc_client_command_pending_del and added new function
4518 silc_client_command_pending_check. Removed the
4519 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4522 * Added cmd_ident, current command identifier, to the client
4523 connection context in lib/silcclient/client.h to keep track on
4524 command identifiers used in command sending. Client's command reply
4525 function handling now supports the mandatory command identifiers.
4527 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4528 funtions in client to fully support pending command callbacks.
4530 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4531 as one of the arguments to the application in the command reply
4534 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4535 before first releasing SILC but came back. Now it is removed again
4536 and should come back nomore. The FORWARDED flag was used only
4537 by the JOINing procedure by forwarding the command packet to router.
4538 Now, the JOINing procedure has been changed to more generic (due
4539 to various router environment issues) and FORWARDED is not needed
4540 anymore for anything. The protocol specification is yet to be
4543 Now, removed silc_server_packet_forward from server and the flag
4544 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4546 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Renamed NAMES command to USERS command. The NAMES was named that
4549 due to historical reasons. Now it is renamed. Also, rewrote
4550 parts of the USERS command. The nickname list is not sent anymore
4551 by the server. Only Client ID and mode lists are sent in the USERS
4552 command. Changed this also to the protocol specification.
4554 The client now resolves the names and stuff after it receives
4555 the USERS list from the server when joining to the channel.
4557 * WHOIS and IDENTIFY commands has been changed to support multiple
4558 Client ID's per command. One can now search for multiple users
4559 in the network by sending only one WHOIS or IDENTIFY command.
4560 Changed the code and the protocol specifications.
4562 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4563 uses silc_server_command_whois_parse to parse the request. */
4565 * If normal server, do not parse the WHOIS and IDENTIFY requests
4566 before sending it to the router. Saves some time.
4568 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Fixed JOIN command on client library. Wrong number of arguments
4571 used to crash the client.
4573 * Added silc_server_channel_has_global function to check whether
4574 channel has global users or not.
4576 * Added silc_server_channel_has_local function to check whether channel
4577 has locally connected clients on the channel.
4579 * The silc_server_remove_from_one_channel now checks whether the
4580 channel has global users or not after given client was removed from
4581 the channel. It also checks whether the channel has local clients
4582 on the channel anymore. If it does not have then the channel entry
4583 is removed as it is not needed anymore.
4585 * The silc_server_notify now checks on JOIN notify whether the joining
4586 client is one of locally connected or global. If it is global then
4587 the channel has now global users on the channel and that is marked
4588 to the channel entry. Also, it now saves the global client to
4589 global list who is joining and JOINs it to the channel. This is
4590 for normal server, that is.
4592 Changed silc_server_send_notify_on_channel,
4593 silc_server_packet_relay_to_channel and
4594 silc_server_packet_send_to_channel check if we are normal server
4595 and client has router set (ie. global client) do not send the
4596 message to that client, as it is already routed to our router.
4598 * Implemented LEAVE notify type handling in silc_server_notify
4601 * Tested LEAVE command in router environment successfully. Tested
4602 with two routers, two servers and two clients.
4606 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4608 * Implemented SIGNOFF notify type handling in silc_server_notify
4611 * silc_server_remove_id now removes the client entry from all channels
4612 it has joined and thusly sends SIGNOFF notify type.
4614 * Rewrote the NAMES list generation in server by removing two excess
4615 loops. The lists are created now inside one loop.
4617 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * silc_server_remove_channel_user checks now also global list
4620 for channel and client.
4622 * silc_server_new_channel_user checks now both local and global
4623 list for channel and client. Fixed a bug in client id decoding.
4624 Used to decode wrong buffer.
4626 * silc_server_channel_message checks now both local and global
4627 list for channel entry.
4629 * Tested channel joining (hence JOIN) in router environment
4630 successfully. Tested with two routers, two servers and two
4633 * Tested channel message sending in router environment successfully.
4635 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Added silc_server_save_channel_key into server.[ch] to save the
4638 received channel key in Channel Key payload processing. It is
4639 also used in JOIN command reply handling.
4641 Equivalent function silc_client_save_channel_key added into
4642 client.[ch] into client library.
4644 * Changed JOIN command reply to send information whether the channel
4645 was created or not (is existing already) and the channel key
4646 payload. Changed protocol specs accordingly.
4648 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4649 the request was sent by ID and not by nickname. Crashed on
4652 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4655 now correctly save the received data.
4657 * silc_server_free_sock_user_data now notifies routers in the
4658 network about entities leaving the network.
4660 At the same time implemented functions silc_server_remove_id
4661 and silc_server_send_remove_id to receive and send REMOVE_ID
4662 packets. The packet is used to notify routers in the network
4663 about leaving entities. The ID removed will become invalid in
4666 * Added function silc_idlist_del_server into server. Removes and
4667 free's server entry from ID list.
4669 * silc_server_private_message function now checks, if we are router,
4670 that the destination ID really is valid ID, naturally.
4672 * In router when NEW_ID packet is received (for new client) the
4673 hash of the Client ID is saved in the ID Cache but the
4674 client->nickname is set to NULL, instead of putting the hash
4677 IDENTIFY command now also checks that client->nickname must be
4678 valid. If it is not if will request the data from the server who
4679 owns the client. Added new function
4680 silc_server_command_identify_check.
4682 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4683 to set the command to already allocated Command Payload.
4685 * Tested private message sending in router environment with two
4686 routers, two servers and two clients. Fixed minor bugs and now
4689 * Fixed segfault from client's NAMES command. Used to crash if
4692 * Forwarded packets must not be routed even if it is not destined
4693 to the receiver. Changed server code comply with this.
4695 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added `require_reverse_mapping' boolean value to ServerParams
4698 structure. If TRUE (not default) the server will require that
4699 the connecting host has fully qualified domain name.
4701 If the reverse mapping is not required and hostname could not be
4702 found the IP address is used as hostname.
4704 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Implemented version string checking to both client and server.
4707 The check is incomplete currently due to the abnormal version
4708 strings used in development version of SILC.
4710 * Changed all command functions in server to use the new
4713 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Changed char *data to unsigned char *data in ID Cache system to
4716 support binary data as ID Cache data. Changed code to support
4717 binary data in lib/silccore/idcache.c.
4719 * Renamed silc_server_packet_relay_command_reply to
4720 silc_server_command_reply as it is normal packet receiving
4721 function. Rewrote the function to accept command replys for
4722 servers and not only for clients.
4724 * Mark remote router always as registered server if we are connecting
4725 to it. Otherwise, commands sent by the router to us are ignored.
4727 * All ID List find routines now returns the ID Cache Entry pointer
4728 as well if requested.
4730 * WHOIS command works now in router environment, tested with two
4731 routers, two servers and two clients.
4733 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4734 in router environment (as it is almost equivalent to WHOIS) but
4735 hasn't been tested thoroughly. Added new functions:
4737 silc_server_command_identify_parse
4738 silc_server_command_identify_send_reply
4739 silc_server_command_identify_from_client
4740 silc_server_command_identify_from_server
4742 * Disabled route cache adding because adding two different ID's with
4743 same IP replaces the old cache entry thus giving wrong route.
4744 The entry->router->connection is always the fastest route anyway
4745 so route cache may not be needed. Of course, new routes maybe
4746 established after receiving the ID when the entry->router->connection
4747 might not be anymore the most optimal.
4749 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Add route cache for received ID for fast routing.
4753 * Added silc_server_packet_route to route received packet on router
4754 that is not destined to us.
4756 * Renamed silc_server_get_route to silc_server_route_get.
4758 * Added id_string and id_string_len fields into SilcServer to
4759 include encoded ServerID for fast comparing without excess
4760 encoding of the ID's.
4762 * Cleaned up WHOIS command on server side. Added following static
4765 silc_server_command_whois_parse
4766 silc_server_command_whois_check
4767 silc_server_command_whois_send_reply
4768 silc_server_command_whois_from_client
4769 silc_server_command_whois_from_server
4771 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4772 arguments in command replies. All command functions should be
4773 updated to use this macro.
4775 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Minor typo fixes on command reply handling on server.
4779 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Added silc_server_command_add_to_channel internal routine to add
4782 the client to the channel after router has created the channel and
4783 sent command reply to the server.
4785 * Added generic silc_server_send_command to send any command from
4788 * Use static buffer with ID rendering instead of duplicating data.
4790 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Fixed a channel user mode bug when joining to a channel server gave
4793 everybody channel founder rights, oops.
4795 * We mark ourselves as the router of the incoming server connection
4796 if we are router ourselves. This way we can check in some packet
4797 sending functions whether it is locally connected server. For
4798 incoming router connections we put NULL.
4800 * For router sending packets locally means now always sending the
4801 packet cell wide; to local clients and local servers. For normal
4802 server sending packet locally means sending it to only local
4805 * Fixed the JOIN command to really work in router environment. If the
4806 channel is created it is always created by the router. Router is
4807 also responsible of making the initial joining to the channel,
4808 sending JOIN notify to the sending server and distributing
4809 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4810 does not exist server doesn't do anything else but forward the
4811 command to the router which performs everything.
4813 * Added silc_server_send_channel_key function to send the Channel Key
4816 * Added silc_server_create_channel_key to create new channel key. The
4817 channel key is now re-generated everytime someone joins or leaves
4818 a channel, as protocol dictates. Note: channel->key_len is the
4821 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4824 packet_receive.[ch] to separate packet sending and receiving
4825 routines. The server.[ch] now includes everything else including
4826 actual packet processing (writing and reading data) and other
4829 Renamed silc_server_private_message_send_internal to
4830 silc_server_send_private_message. The routine is still though
4831 used only to relay private messages as server does not send
4832 private messages itself.
4834 Renamed silc_server_new_channel to silc_server_create_new_channel
4835 and added new function sicl_server_new_channel that handles the
4836 incoming New Channel packet. Added also new sending function
4837 silc_server_send_new_channel to send New Channel Payload.
4839 * Added new function silc_server_notify to process incoming notify
4840 packet to the server/router. Server may then relay the notify
4841 to clients if needed.
4843 * Added new function silc_server_new_channel_user to process incoming
4844 New Channel User packet. Router will redistribute the packet and
4845 send JOIN notify to its local clients and locally connected servers
4846 if needed. Normal server will send JOIN notify to its local client
4847 on same channel when received this packet. Added also corresponding
4848 sending function silc_server_send_new_channel_user to sent the
4851 * Added boolean route argument to send_notif_to_channel and
4852 packet_send_to_channel functions to attempt to route the packet
4853 if it is TRUE and send only locally if it is FALSE.
4855 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * silc_server_replace_id now broadcasts the received replace ID
4858 packet if it is not broadcast packet already. The router must
4859 broadcast to inform other routers about changed ID.
4861 * Added backpointer to server's router into SilcServer context in
4862 silcd/server_internal.h.
4864 * Fixed silc_server_packet_broadcast to send correct broadcast
4867 * The channel key is now distributed to the local client as soon
4868 as it is received from the router (in router environment) so that
4869 no other packet may be sent for the channel until client has
4872 * silc_server_remove_channel_user now broadcasts the received
4873 Remove Channel User packet if it is not broadcast packet already.
4874 The router must broadcast to inform other routers about removed
4877 * Added users field into SilcPacketContext that is a reference count
4878 of the context. One can increase the reference count by calling
4879 silc_packet_context_dup which is now changed to just increase the
4880 reference count instead of duplicating the data. The reference
4881 count is decresed by calling silc_packet_context_free that will
4882 free the data after the reference count hits zero.
4884 For now on the packet context and everything allocated into it
4885 (including the raw packet from network) must be freed by calling
4886 the new silc_packet_context_free function. Added also new function
4887 silc_packet_context_alloc that must be used now to allocate the
4888 context. This also means that if a routine is asynchronous from
4889 silc_[client/server]_packet_parse_type the packet context must
4890 be duplicated by calling silc_packet_context_dup. Otherwise it
4891 gets free'd after silc_[client/server]_packet_parse_type returns.
4892 Also, one must remember that if packet is duplicated then its
4893 reference count must be decresed by calling the free function as
4894 many times as it was duplicated.
4896 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4897 from both client and server.
4899 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Made joining to a channel working in router environment.
4903 * Cleaned up JOIN command on server side and create function
4904 silc_server_command_join_channel internal routine to make the
4907 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Changed silc_command_pending list to SilcDList. Also, added
4910 `ident' field to SilcServerCommandPending structure to identify
4911 the reply and to call correct callback.
4913 Added silc_server_command_pending_check function to replace the
4914 corresnponding macro. The silc_command_pending list is not
4917 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4918 to set identifier to previously allocated Command Payload. It
4919 is used to set identifier for command when resending Command
4922 * Added silc_command_payload_encode_payload to encode Command
4923 Payload buffer from SilcCommandPayload structure.
4925 * Added silc_argument_payload_encode_payload to encode Argument
4926 payload buffer from SilcArgumentPayload structure.
4928 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Changed WHOIS command to support router connection on server side.
4931 The whois request is always sent to router unless the server is
4932 standalone server. After server has received the reply from the
4933 router will it send the reply to the client.
4935 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4936 broadcast received broadcast packet. The function is used only
4937 by router. The broadcast packet is always sent to the router's
4940 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4941 render given ID to printable string, for log files for example.
4943 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Made basic router to router connections working. At least they
4946 can now connect to each other but nothing really works the way
4947 they are supposed - yet.
4949 * Added new initiator token to RouterConnection configuration
4950 file in silcd/serverconfig.[ch]. It is used to tell whether we
4951 are the initiator to the remote router or whether we'll expect
4952 the other end to connect.
4954 * Moved registering of listener task to silc_server_init, hence
4955 the server starts listenning as soon as it is run, even if it
4956 does not have connections to other routers. Let's see how well
4959 * Changed default connection retry timeouts for more suitable in
4962 * Removed cipher and such arguments from silc_idlist_add_client
4963 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4964 Added new function silc_idlist_add_data to add the keys and stuff
4967 * Added SilcIDListData structure and added it to SilcClientEntry
4968 and SilcServerEntry as their first field in the structure. This
4969 way we can explicitly cast the ID entries to the SilcIDListData
4970 structure and get common data for the entries. In past, we had
4971 to first check what type of connection it is and then cast it to
4972 correct ID entry type. Now, we can directly cast the opaque
4973 pointer to the SilcIDListData (no matter what ID entry it actually
4974 is) and get the data needed.
4976 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4979 in some circumstances even if threre were timeout tasks, though not
4980 IO tasks, but tasks anyway. Now fixed.
4982 * Defined SilcServerConnection structure to hold connection specific
4983 stuff about directly connected servers and routers. The definition
4984 is currently in silcd/server_internal.h. I thought about having
4985 a bit more important role fro this struct but for now it is used
4986 only when connecting to other server (or router actually).
4988 * Added connecting retry support in server when connecting to
4989 router(s). The retry feature implement exponential backoff
4990 algorithm. Also, added SilcServerParams structure to hold default
4991 parameters for server. For now, it include these retry settings
4992 and are hard coded. After server is moded to be as Silc Server
4993 Library this structure will be more important.
4995 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Changed client librarys channel->clients table to SilcList and
4998 changed code accordingly.
5000 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5002 * Changed client's channel table to SilcList and changed code
5003 accordingly. Also changed SilcChannelClientEntry to include back-
5004 pointer to the channel so that client entry can use that structure
5005 as list as well and we have fast cross-reference to the channel.
5006 This change dramatically decreased the complexity of channel
5007 handling with client entry and vice versa (removed one extra
5008 loop when searching for channel entry from many functions).
5010 * Changed server->sim from table to SilcDList and changed code
5013 * NAMES command can now be used from user interface. It will show
5014 the user list on the channel, neatly.
5016 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5017 Code now saves realname of the user if it becomes available.
5019 * Renamed configure.in to configure.in.pre and made ./prepare
5020 script to automatically add correct version string to
5021 configure.in which it creates from configure.in.pre.
5023 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * NAMES command reply now shows users mode with the nickname when
5028 * Moved silc_client_ch[u]mode[_char] functions from
5029 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5030 place sucks, they are utility functions and should be in some
5033 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5035 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5038 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added TRQ (efficient deque and list library) into lib/trq. This is
5043 a very good list library that is currently used in the SILC. Defined
5044 SilcList API over the library because I didn't like the API very
5045 much. See lib/trq/silclist.h for the API and examples of how to
5046 use the API. Fixed various places in the code to use the new
5047 SilcList API. The SilcList is meant for lists that has a structure
5048 already defined as a list. It is not suitable to add just some
5049 context to the list (in TRQ, the context is the list actually).
5051 So, I defined SilcDList that can be used for the purpose where
5052 predefined list structure does not exit. This can be used as
5053 such list. Now some context just can be added to the SilcDList.
5054 Currently this list is not used in the SILC just yet, though there
5055 are a lot places where this can replace dynamically allocated
5056 tables and I will fix these places, later, to use SilcDList.
5057 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5058 and use TRQ internally).
5060 Also fixed some annoying warning messages that the original TRQ
5061 code generated. Also minor changes to TRQ's Makefile.in.
5063 * Added support for querying by Client ID to both WHOIS and
5064 IDENTIFY commands into server, as required by the protocol.
5066 * Removed method function pointers from SilcBuffer structure. They
5067 weren't used to anything and just increased the context size for
5068 no good reason. This change also made silc_buffer_alloc and
5069 silc_buffer_free functions inline functions.
5071 * Disabled command flooding detection support until it's fixed so
5072 that it accepts commands in but does not execute them more than once
5075 * Added silc_net_localhost(), to return local hostname, into
5076 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5077 that must be initialized before calling silc_client_init.
5079 * Added new function: silc_server_send_notify_on_channels to send
5080 notify messages to all channels client has joined. It is assured
5081 that the message is sent only once per client.
5083 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5084 lib/silcutil/silcutil.[ch] as silc_format function. The new
5085 function is generic and is used by server as well, not only by
5086 the logging routines.
5088 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5089 the provided version string was not acceptable. Added new function:
5090 silc_ske_check_version into lib/silcske/silcske.h. The function
5091 must be implemented by the application (client or server) and it
5092 does not reside in the SKE library. The function checks the version
5093 string remote end sent.
5095 * Added back pointers (to opaque context and to SilcSocketConnection)
5096 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5098 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5099 duplicate packet context structure.
5101 * Changed `notify' client operation to send same arguments as client
5102 receives from server except for ID's. ID's are mapped to correct
5103 ID entry and that is returned. Also, if channel entry is not sent
5104 by server but the notify is for channel the channel entry is sent
5105 to application (otherwise application doesn't know that it is for
5106 channel (library gets it from packet's Destination ID)).
5108 * Added silc_client_remove_from_channels into client library to
5109 remove a client from all channels it has joined to. Used when
5110 received SIGNOFF notify from server. Added also new function
5111 silc_client_replace_from_channels to replace old ID entry with
5112 new ID entry on all channels. Used when received NICK_CHANGE
5115 * Fixed ID Cache list handling in silc_idlist_get_client in
5116 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5117 to get (or query) client by ID.
5119 * Updated TODO list.
5121 * Added connection authentication status message defined by the
5122 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5123 support for these into the code in client and server side.
5125 * Added generic function silc_client_send_command to send any command
5126 with variable argument list. Application should use this function
5127 to send commands if the command functions provided by the library
5128 does not suite for the application's user interface needs.
5130 * Added new `failure' client operation. Application is notified about
5131 received failure packet if client is executing a protocol. In this
5132 case the protocol's execution has failed.
5134 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5135 is required by the protocol.
5137 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5138 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5141 * Added status flag to SilcSKE object to indicate realtime status
5142 of the SKE protocol.
5144 * Application receives now exactly same command reply arguments as
5145 the library receives from server. However, if ID is received the
5146 corresponding ID entry is returned to the application (eg. Client
5147 ID is mapped to correct SilcClientEntry entry and that is returned).
5148 Changed command_reply client operation due to this change.
5150 * Changed all ID's in commands and in command replys as ID Payloads.
5151 Change affected both client and server side codes.
5153 All ID's sent in SILC network (with execption of ID's in SILC
5154 Packet header) are sent in ID Payload to support variable length
5157 * Server now notifies nick changes and notifies all clients on
5158 the channels about the new nickname (about the new Client ID,
5161 * Implemented CMODE command to change channel modes. Supports all
5162 channel modes defined by the protocol specs except ban and invite
5163 lists. (Also, private channel key mode is supported but support for
5164 setting private channel key in client is missing, thus, this mode
5165 has no effect on client side (except that server requires that the
5166 client uses private channel key and normal channel traffic does not
5169 Also, invite mode works per se, but INVITE command does not work
5170 yet correctly, so you can set channel as invite only channel but
5171 inviting clients to the channel does not work (it is yet to be
5172 thought what's the best way to do it).
5174 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5175 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5176 Implemented CUMODE command to change user's mode on the channel.
5177 Supports all modes defined by the protocol specs.
5179 * Added NAMES command reply to return users modes on the channel.
5181 * Removed unnecessary and slow ciphers from lib/silccrypt.
5183 * Set SO_KEEPALIVE option to connection sockets by default.
5185 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5187 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5188 redefined the Notify Payload into protocol specs.
5190 * Added silc_id_payload_parse_id to get ID directly from raw
5193 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5196 accept searching by Client ID as well.
5198 * Added support for LEAVE and SIGNOFF notify types in client library.
5200 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5201 to parse ID Payload from raw data.
5203 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Added flags parameter into silc_ske_assemble_security_properties
5206 function in lib/silcske/silcske.[ch].
5208 * Changed notify client operation to fit better for notify messages
5209 sent by server. The notify payload received from server is now
5210 passed to the application (after parsing it to SilcNotifyPayload).
5211 It is application's responsibility to retrieve the arguments
5212 from the payload and show the message the way it wants. The message
5213 sent by server is implementation specific.
5215 * Changed public keys to comply with the protocol specification.
5216 Old public keys are not supported anymore and are not compatible.
5218 * Removed nickname from Channel Payload as the latest draft removed
5219 it. The client must resolve the nickname from the NAMES command
5220 reply received when it joined the channel.
5222 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5224 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Fixed some errors in protocol specification drafts.
5228 * Created lib/silccore/silcnotify.c to implement Notify Payload
5229 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5230 generic payloads described by protocol specifications. The file
5231 includes implementations for ID Payload and Argument Payload.
5233 * Changed Command Payload implementation to use the new Argument
5234 Payload. Changed command_xxxx_payload to command_payload_xxxx
5235 to comply with SILC coding conventions.
5237 * Added suppport for Argument Payload handling in Notify Payload
5238 implementation as protocol requires it. Added the new support
5239 into server and client lib as well.
5241 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added support for multiple nicknames on same channel. [n] is
5244 added locally to the nickname if there are more than one same
5245 nicknames on the channel.
5247 * Server now sends all nicknames that matched WHOIS request.
5248 Client also shows the list received from server.
5250 * Added TOPIC command to client side. User can now set and show
5251 current topic on channel.
5253 * Added MOTD command to client and server. Also, server sends the
5254 motd when client connects to the server.
5256 * Changed version strings to comply ISO 8601.
5258 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Fixed protocol error handling in client library. It should now
5261 cope even if the SKE fails for some reason.
5263 * Made new protocol specification drafts for submitting to IETF.
5265 * Implemented TOPIC command to server in silcd/command.c.
5267 * Added two new notify types into lib/silccore/silcnotify.h:
5268 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5269 notify nickname change and topic setting/change on a channel.
5271 * API change of command_reply operation in client library. The
5272 application gets now the status type received from server as well.
5274 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5278 * Cras fixed and optimized the packet handling even further and
5279 it should work now. Minor change to the prototype of function
5280 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5282 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Added new function into lib/silcutil/silcschedule.[ch]:
5285 silc_schedule_with_fd to select() a specified fd. The function
5286 returns after timeout expires or data arrives or goes. The
5287 function is used by packet routines to wait that all data is
5288 received from network.
5290 * Fixed data reading from network in lib/silccore/silcpacket.c.
5291 The code now assures that all data is read from the fd and then
5292 continues packet processing. This was a bug fix since the code
5293 used to drop some data in some circumstances.
5295 * Added new function into lib/silcclient/client.[ch]:
5296 silc_client_start_key_exchange to start key exchange after
5297 connection has been established to server. The code internally
5298 now uses this funtion but its main purpose was to provide it
5299 for applications that perform their own connecting. After
5300 application has created a connection it merely calls this
5301 function to start the key exchange between client and server.
5302 The library takes care of everything else after that.
5304 Updated also lib/silcclient/README to explain the usage of
5307 * Do not send to application information that connection has
5308 been established. Application gets notified it by connect
5311 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Applied cras's patch to add silc_schedule_one function. The
5314 function runs scheduler once and returns.
5316 * Fixed the scheduler after cras messed it up. The timeout
5317 handling works now as it's supposed to work.
5319 * Added into lib/silccore/ silcnotify.h to include notify
5320 message types support. Changed silc_server_send_notify*
5321 functions, in server.[ch], to support those new notify types.
5322 Added the support for the notify types into client library,
5323 as well. Added new notify client operation into ops.h in
5326 * Changed silc_server_packet_send_to_channel to send normal
5327 packets instead of just channel message packets. The function
5328 is now used to send the notify packets to channels. It is not
5329 used to send channel message packets anymore, as server never
5332 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5333 va_arg()s as it seems to require it nowadays. I guess, if SILC
5334 is compiled with older va_arg() the new code should work anyway.
5336 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Splitted core library. Core library (lib/silccore) includes
5339 now only SILC protocol specific core (and common) components.
5340 Created new utility library (lib/silcutil) that includes more
5341 generic purpose stuff. The stuff for util library was taken
5342 from the old core library. This was minor and easy split.
5344 * Created SILC Client Library (lib/silcclient) that includes
5345 implementation of the SILC client without user interface. This
5346 was major move from silc/ directory. The code has been changed
5347 so that it is transparent towards the user interface. The
5348 silc/ directory includes now the same user interface as before
5349 and it uses the new client library. Read lib/silcclient/README.
5350 Basicly, the client library performs everything else related
5351 to SILC except user interface handling. Also, configuration
5352 files are considered to be part of user interface and library
5353 does not handle them.
5355 This change also changed a lot of structures, function naming etc.
5356 Most important change was that SilcClientWindow object was
5357 renamed to SilcClientConnection in the client library. Created
5358 also new file lib/silcclient/ops.h. Also added new files
5359 silc/local_command.[ch] and silc/client_ops.[ch].
5361 All these changes were made to make it easier for user interface
5362 designers to create what ever user interface for the SILC client
5365 It is also expected that the server will be moved to lib
5366 directory as well and SILC Server Library will be created;
5367 sometimes in the future.
5369 * Removed Local commands from lib/silccore/silccommand.h as
5370 they are application specific and new client library does not
5371 handle any of those anymore.
5373 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5374 old client implementation in silc/.
5376 * Added support for callback functions in SILC_LOG_* macros.
5377 Application can now set its own callbacks that will be called
5378 instead of using the default functions that will always print
5379 the debug messages to stderr (or stdout). Also, debugging can
5380 now be disabled by setting silc_debug to FALSE and re-enabled by
5381 setting it to TRUE. Note, that logging will still work even
5382 if debugging is disabled.
5384 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5385 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5386 silc_log_reset_debug_callbacks.
5388 * To enable debugging in silc client one must give now -d
5389 option on command line.
5391 * Changed silc_schedule_init to automatically allocate task queues
5392 if they are not allocated before calling it.
5394 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added GMP 3.1 into math library.
5398 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5401 a channel in SILC network. The packet is used by servers and
5402 routers to notify other routers that user has left a channel.
5403 This little feature was missing until now. Added the feature
5404 to protocol specification as well.
5406 Added functions: silc_server_send_remove_channel_user and
5407 silc_server_remove_channel_user into server.[ch].
5409 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5410 lib/silccore/silcpacket.h. However, they are not implemented
5413 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Fixed joining to a channel and sending channel messages
5416 between server and router. The channel message sending should
5417 now work inside a cell.
5419 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Fixed the private message sending between server and router.
5422 The private message sending should now work inside a cell.
5424 * Added silc_server_replace_id into server.[ch] to replace
5425 existing ID in the SILC network.
5427 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5428 and silc_idlist_replace_server_id into idlist.[ch] in server.
5430 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Fixed the server to server connections. Server can again now
5433 connect to router. Router to router connections probably does
5436 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Added dynamic protocol registering support. Now protocols can
5439 registered and unregistered on the fly. Patch by cras.
5441 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Added lib/contrib directory to hold routines that some platforms
5444 don't have but are needed by SILC.
5446 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5447 into lin/contrib to provide getopt() and getopt_long() for
5448 those who don't have it.
5450 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added AWAY command to client. When away message is set and
5453 client receives a private message packet the client automatically
5454 replies to the sender with the away message.
5456 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5457 bug seemed to be the cause of recent problems when compiling
5460 * Added version detection support to SKE protocol specification
5461 and added the new changes to the SKE implementation as well.
5462 There were other minor changes in the SKE protocol as well.
5464 Many changes in lib/silcske/silcske.[ch] and in
5465 lib/silcske/payload.[ch].
5467 * Added ^U functionality, clear input line. Patch from cras.
5469 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Mainly small bugfixes on core library. Fixed some debugging
5472 logging and buffer overflow in silclog.c.
5474 * Updated config.sub and config.guess on the distribution tree.
5476 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Added command lagging support in server. Client may execute
5479 commands now only once in two seconds.
5481 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Optimized packet reception. MAC computation and checking is now
5484 also more optimized. A lot previously duplicated code is now
5485 used as generic by both client and server.
5487 * Fixed key pair generation in clientutil.c
5489 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Added into lib/silccore/silcbufutil.[ch] new function;
5492 silc_buffer_realloc.
5494 * Moved generic packet sending/encryption functions to
5495 lib/silccore/silcpacket.[ch] from client and server. Some
5496 rewriting of the functions.
5498 * Moved all generic packet reception/decryption functions to
5499 lib/silccore/silcpacket.[ch] from client and server. The
5500 packet processing is now much cleaner in both client and server.
5501 These were major changes in both client and server.
5503 * Created many common functions in server to do packet sending.
5504 Previously code were duplicated a lot, this has been removed
5507 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Rewrote major parts of the ID cache system. Don't know
5510 whether it is better now or not but at least the API is more
5513 * Major rewrite on ID cache stuff on client because of the ID
5514 cache API changes. Added idlist.c to client.
5516 * Also major rewrite on ID cache stuff on server as well.
5517 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5518 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5519 in hand, instead they are all put into the ID cache system now.
5520 All server_idlist_* routines uses ID cache now instead of
5521 traversing its own lists (those lists does not exist anymore).
5522 SilcIDList though still exists. Also, SilcXXXEntry's are
5525 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Finally made the SKE implementation compliant to the protocol
5528 specification. All mp integers are now binary encoded as
5529 opposed being HEX encoded.
5531 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5534 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5535 functions: silc_[encode/decode]_pem. Also added function
5536 silc_encode_pem_file to PEM encode with newlines ('\n') for
5539 * SILC public keys are now encoded either PEM or binary. Same
5540 option is for private keys as well. By default private keys
5541 are binary encoded and public keys PEM encoded. Silly HEX
5542 encoding were removed.
5544 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5545 function to create fingerprints.
5547 * Fixed a bug in SHA1; does not change the original data anymore.
5549 * Partly implemented INFO command on client and server side.
5550 Fixed CLEAR command. Changes to SERVER command; show current
5551 server(s) when giving command without arguments. Added
5552 VERSION command to client.
5554 * Added check to server that unregistered connections cannot
5555 execute commands (unless it is specificly allowed).
5557 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Fixed screen refresh.
5561 * Fixed channel joining bug from client. On some circumstances
5562 client tried to join to a channel it had already joined.
5564 * Added public key verification process into client's protocol.c.
5565 The client now verifies the public key from user and saves
5566 it into ~./silc/serverkeys/ directory.
5568 Added into: clientutil.[ch]: silc_client_verify_server_key.
5570 * Changed SKE protocol's silc_ske_initiator_finish function
5571 to accept callback function that verifies the received public
5572 key. Removed old silc_ske_verify_public_key function.
5574 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5577 silc_pkcs_private_key[_data]_set.
5579 * Made the password and public authentication more cleaner in
5580 server's protocol.c.
5582 * Removed historic and obsolete protocol `channel_auth' from
5583 both client and server.
5585 * Removed wrong way of sending command status messages from
5586 server to client in server's command.c. The old way violated
5587 protocol specification.
5589 Changes to silccore/silccommand.[ch]: removed
5590 silc_command_encode_status_payload -> not needed anymore,
5591 changed silc_command_encode_payload_va to accept extra
5592 argument on variable argument list. The argument type must
5593 now be provided to the function. Also, added new function:
5594 silc_command_encode_reply_payload_va which is same as
5595 normal command_encode_payload_va except command status type
5596 is provided as extra argument.
5598 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added ~./silc directory handling. The directory includes the
5601 public and private keys for the client.
5603 Added silc_client_check_silc_dir, silc_client_create_identifier
5604 and silc_client_load_keys.
5606 * Implemented SILC protocol compliant public key. Added public
5607 and private key saving to and loading from files.
5609 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5610 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5611 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5612 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5613 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5615 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5616 silc_pkcs_load_[public/private]_key.
5618 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added silc_server_get_route (route.[ch]) to get connection
5621 data for the fastest route for given ID.
5623 * Implemented INVITE command on client and server. The command
5624 were re-defined in the SILC Protocol Specification and the
5625 implementation now complies with the specification.
5627 * Implemented PING command on client and server.
5629 * Implemented NAMES command on client and server. The server side
5630 supports currently only normal server not router server yet.
5631 Some changes to NAMES definition in SILC protocol specification.
5633 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Implemented LEAVE command on client and server.
5637 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5638 again. This change was made to the protocol as well. Server
5639 should not violate the protocol specification anymore.
5641 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5644 was tested. SOCKS4 was not but should work anyway.
