3 * Fixed the backup resuming protocol to work in multiple
4 router environment. Affected file silcd/server_backup.c.
6 * Route packet only to one router in the function
7 silc_server_packet_send_to_channel. Affected file is
10 * Fixed silc_server_send_notify_dest to set the broadcast
11 flag. Fixed the silc_server_send_notify_topic to actually
12 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
13 Affected file silcd/packet_send.c.
15 * Changed the SFTP Filesystem interface. Changed the
16 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
17 the filesystem operation function. The SilcSFTPFilesystem
18 is now a context that is allocated by all filesystem allocation
19 functions and it already includes the operations structure
20 and filesystem specific context. It is given as argument
21 now to the silc_sftp_server_start. This made the interface
22 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
23 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
25 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
27 * Changed the backup router adding and getting interfaces
28 in the server. The router that will be replaced by the
29 specified backup router is now sent as argument. Affected
30 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
33 * Added silc_net_addr2bin_ne to return the binary form of
34 the IP address in network byte order. Affected files
35 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
37 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Check for existing server ID in silc_server_new_server
40 and in silc_server_connect_to_router_final and remove the
41 old entry if it exists. Affected file silcd/packet_receive.c,
44 * Send the channel message always to only one router, either
45 in upstream or downstream. Affected file is
48 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
50 * Wrote the definition of the backup resuming protocol to the
51 protocol specification.
53 * Removed one redundant channel key generation from normal
54 server during joining procedure. Removed one redundant
55 channel key sending from server to router during joining
56 procedure. Affected file silcd/command.c.
58 * Made minor bugfixes to the backup router resuming protocol.
59 Affected file silcd/server_backup.c, server.c.
61 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
63 * Added --disable-asm configuration option. Affected files
64 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
67 * Implemented the backup resuming protocol that is used to
68 resume the primary router position in the cell after the
69 primary router comes back online. Affected files
70 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
71 and silcd/server_util.[ch].
73 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
75 * Sleep two (2) seconds after sending QUIT command to server.
76 Affected file lib/silcclient/command.c.
78 * Assure that if outgoing data buffer is pending do not force
79 send any data. Affected file silcd/packet_send.c.
81 * Assure that if outgoing data buffer is pending do not force
82 send any data. Affected file lib/silcclient/client.c.
84 * Implemented the backup router support when the primary router
85 goes down. The servers and routers can now use the backup
86 router as new primary router without loosing connectivity.
88 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
91 in the server to indicate disabled entry. All data read
92 from the connection will be ignored and no data is sent
93 for entry that is disabled. Affected files are
94 silcd/idlist.h, silcd/server.c.
96 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
98 * Created SFTP client and server test programs in the
99 lib/silcsftp/tests directory.
101 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Implemented memory filesystem (virtual filesystem) for
104 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
107 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
109 * Implemented the SFTP (SSH File Transfer Protocol) to the
110 lib/silcsftp. It includes SFTP client and SFTP server
113 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
115 * Moved lib/silccore/silcprotocol.[ch] to the
116 lib/silcutil library.
118 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
119 take variable argument list pointer as argument. Affected
120 file lib/silcutil/silcbuffmt.[ch].
122 * Added silc_buffer_set function that is used to set data
123 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
124 Affected file lib/silcutil/silcbuffer.h.
126 * Changed various routines in the core library to use the new
127 silc_buffer_set instead of allocating new buffer only for
130 * Added 64-bit value formatting and unformatting support to the
131 silc_buffer_[un]format routines. Affected file is
132 lib/silcutil/silcbuffmt.[ch].
134 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
135 to includes/bitmove.h.
137 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
139 * Fixed channel user mode saving in client library. Affected
140 file lib/silcclient/command[_reply].c.
142 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
144 * Defined the file transfer to the SILC Protocol. Added
145 new packet type SILC_PACKET_FTP and defined File Transfer
146 Payload. The mandatory file transfer protocol is SFTP
147 (SSH File Transfer Protocol). Affected file in addition
148 of the internet draft is lib/silccore/silcpacket.h.
150 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
151 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
152 is used as part of backup router protocol when the primary
153 router of the cell is back online and wishes to resume
154 the position as primary router.
156 * Redefined the MAC generation keys in the protocol. The
157 same key is not used anymore in both direction. Both
158 direction will now use different keys for sending and
159 receiving. This fixes a potential security flaw. This
160 change causes incompatibilities in the protocol.
162 * Redefined also the MAC computation from the packet.
163 An packet sequence number is now added to the MAC
164 computation. This prevents possible replay attacks against
165 the protocol. This change too causes incompatibilities
168 Added `sequence' field to the SilcPacketContext to hold
169 the current sequence number for the packet.
171 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
173 * Added `created' field to the SilcIDListData in the file
174 silcd/idlist.h to indicate the time when the entry was
177 * Added `created' field to the SilcChannelEntry too. Affected
180 * Added `creation_time' aguments to all the announcement functions
181 in the server. If it is provided then only the entries that
182 was created after the provided time frame are actually
183 announced. Affected file silcd/server.[ch].
185 * The protocol says that the Channel ID's IP address must be
186 based on the router's IP address. Added check for this in
187 the silc_server_new_channel when processing incoming New Channel
188 Payload. Affected file silcd/packet_receive.c.
190 * Print out the correct version with --version in SILC client.
191 Affected file irssi/src/silc/core/silc-core.c.
193 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
195 * Fixed WHOWAS command to check for completnes of the client
196 entry always, not just when the command is coming from client.
197 Affected file silcd/command.c.
199 * Added new function silc_server_packet_queue_purge to purge the
200 outgoing data queue to the network. After the function returns
201 it is guaranteed that the outgoing packet queue is empty.
202 Affected file silcd/packet_send.[ch].
204 * Purge the outgoing packet queue in the rekey protocol's final
205 callback to assure that all rekey packets go to the network
206 before quitting the protocol. Affected file silcd/server.c.
208 * Added silc_client_packet_queue_parse as similar function as
209 in server to the client library. The affected file is
210 lib/silcclient/client.c.
212 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
214 * Splitted silcd/server.c and created silcd/server_util.[ch]
215 for utility functions.
217 * Added new socket flag SILC_SF_DISABLED to indicate that the
218 connection is open but nothing can be sent to or received from
219 the connection. Affected file lib/silcutil/silsockconn.[ch].
220 The checking for disabled socket is checked in the low level
221 silc_socket_write and silc_socket_read functions.
223 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
225 * Allow only nicknames and channel names that fits into the
226 7-bit unsigned char ASCII set. Affected file silcd/command.c.
228 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
230 * When processing JOIN command reply in server check that if
231 the channel exists in our global list we'll move it the local
232 list. Affected file silcd/command_reply.c.
234 * Fixed the check whether client is joined on the channel already
235 in JOIN command. Affected file lib/silcclient/command.c.
237 * Fixed the JOIN command reply to check whether the channel
238 already exists. Affected file lib/silcclient/command_reply.c.
240 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
242 * Added silc_ske_status_string to map the SKE error numbers
243 to readable strings. The affected files are
244 lib/silcske/silcske[_status].[ch].
246 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Do not show the private channels on the WHOIS channel list
249 as it is not allowed by the protocol. The affected file is
252 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Assure that the packet length digged from the actual packet
255 is something sensible in the silc_packet_decrypt_rest_special
256 in lib/silccrypt/silcpacket.c.
258 * Free and NULL the allocated pointer in silc_hmac_alloc if
259 the HMAC allocation fails. The affected file is
260 lib/silccrypt/silchmac.c.
262 * Print the selected security properties to the log files in
263 the server. Affected file silcd/protocol.c.
265 * Add SKE's reference counter even if calling the completion
266 callback manually. Otherwise it goes negative, although it
267 does not cause any problems. The affected file is
268 lib/silcske/silcske.c.
270 * Remove the client entry with short timeout after giving the
271 KILL command. Affected file lib/silcclient/command.c.
273 * Fixed to send error reply in WHOIS and IDENTIFY commands in
274 case all found clients are already disconnected (WHOWAS would
275 found them) in the server. Affected file silcd/command.c.
277 * Update the last_receive (time of last data received) to be
278 updated only when received private or channel message so that
279 the idle time showed in WHOIS makes more sense.
281 * Added boolean field `valid' in to the SilcClientEntry in the
282 client library to indicate whether the entry is valid or not.
283 This fixes the nickname change bug on channel when changing
284 the nickname to be same than the old (like nick to Nick) the
285 nickname formatter doesn't set the new nick anymore to Nick@host.
286 Affected file lib/silcclient/idlist.[ch].
288 * Now actually fixed the nickname changing on disconnection.
289 Added new function silc_change_nick to the Irssi SILC Client.
290 Affected file irssi/src/silc/core/client_ops.c,
291 irssi/src/silc/core/silc-nicklist.[ch].
293 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
295 * Check that the public key exists in the GETKEY command before
296 trying to encode it. Affected file silcd/command.c.
298 * Print some notifications on received public keys with GETKEY
299 command in the Irssi SILC Client. Affected files are
300 irssi/src/fe-common/silc/module-formats.[ch],
301 irssi/src/silc/core/client_ops.c.
303 * Use IDENTIFY command to resolve the server information in the
304 GETKEY command instead of INFO command. Affected file
305 lib/silcclient/command.c.
307 * All command reply functions in the client library now calls
308 the pending command reply callbacks even if an error has
309 occurred. The server has done this a long time and now it was
310 time to move the client library to this as well. Now all
311 errors can be delivered back to the pending command reply
312 callbacks if necessary. Affected files are
313 lib/silcclient/command[_reply].[ch].
315 * Change the nickname on disconnection back to the username
316 because in reconnect the server will enforce it to it anyway.
317 Affected file irssi/src/silc/core/silc-servers.c.
319 * Fixed a config file parsing bug in the Irssi SILC client.
320 Affected file irssi/src/silc/core/clientconfig.c.
322 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
324 * When printing the channel mode on JOIN, verify that the
325 channel key and channel's HMAC are valid. Affected file
326 irssi/src/silc/core/client_ops.c.
328 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
331 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
332 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
334 * Removed channel key rekey task deleting from the function
335 silc_server_save_channel_key. Affected file silcd/server.c.
336 Added explicit timeout task context instead that is used to
337 delete the task if we are registering a new task before the
338 new task has elapsed.
340 * When channel key rekey occurs the client library now saves
341 the old channel key for a short period of time (10 seconds) and
342 is able to use it in case some is still sending channel
343 messages encrypted with the old key after the rekey. Affected
344 file lib/silcclient/[idlist.h|client_channel.c].
346 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
348 * Added check to the silc_server_new_id_real to not accept
349 new ID if it is the sender's own ID. Affected file is
350 silcd/packet_receive.c.
352 * Assure that we do not announce ourself or the one we've
353 sending our announcements when we're router and are announcing
354 servers to our primary router. Affected file silcd/server.c.
356 * Fixed silc_server_command_identify_check_client to assemble
357 correct WHOIS packet. It send corrupted WHOIS packet and
358 caused problem with router to router connections. Affected
359 file silcd/command.c.
361 Fixed also silc_server_command_whois_check the same way
362 as for the IDENTIFY command.
364 * Added new SilcIDListStatus to the server in the SilcIDListData
365 structure. The status now includes the current status of
366 the entry (like registered, resolved etc.). Affected file
367 silcd/idlist.[ch]. Defined a bunch of different status types
368 as well. This replaced the old boolean registered field as well.
370 Added resolve_cmd_ident field to the SilcClientEntry structure
371 too so that if the entry is for example being resolved so
372 another command may attach to the same pending command reply
373 without requiring to resolve the same entry again. This concept
374 should optimize the WHOIS and the IDENTIFY resolving under
375 heavy load by taking away unnecessary resolving for entries
376 that are being resolved already.
378 Added support for adding multiple pending commands for one
379 command idenfier. Affected file silcd/command[_reply].[ch].
381 * Fixed WHOIS and IDENTIFY save to remove the cache entry
382 before deleting the data. Otherwise the hash table will have
383 freed data in comparison functions. Affected file is
384 silcd/command_reply.c.
386 * Fixed silc_idlist_replace_client_id to add the new entry to
387 the cache with NULL nickname. Otherwise there will be invalid
388 memory as the nickname after the nickname is freed. Affected
389 file silcd/packet_receive.c.
391 * Fixed the silc_idlist_get_clients_by_hash. The entries was
392 saved into wrong slots because the previous number of entries
393 was not taken into account. Affected file silcd/idlist.c.
394 Fixed same thing in silc_idlist_get_clients_by_nickname too.
396 * If we are router and we receive JOIN notify to a channel that
397 does not have any users then notified client is marked as the
398 channel founder, as it is it. The affected file is
399 silcd/packet_receive.c
401 * Added to the extended hash table API's table_del_*ext functions
402 the destructor as argument too, so that the caller can decide
403 which destructor to use or whether to use destructor at all.
404 Affected file lib/silcutil/silchashtable.[ch].
406 * Fixed ID Cache purging. It actually deleted the entries from
407 the hash table after the data was freed. The hash table ended
408 up comparing freed memory. The affected file is
409 lib/silccore/silcidcache.c.
411 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
413 * Fixed Irssi SILC client's KILL command's HELP syntax.
415 * The USERS command now resolves the detailed user information
416 if the userinfo field is missing. Affected file is
417 lib/silcclient/command_reply.c.
419 * Do not print error in silc_file_read if the read file does
420 not exist. Just silently return NULL. Affected file is
421 lib/silcutil/silcutil.c.
423 * Fixed the silc_log_output to not wine about NULL filename
424 and to not create some bogus " " filename. Affected file is
425 lib/silcutil/silclog.c.
427 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Fixed various printing bugs on the user interface in the
430 Irssi SILC Client. Minor changes that were forgotten from
433 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
435 * Fixed the configure.in.pre and the compilation and distribution
436 environment to support the new autoconf 2.52. That version is
437 now required to compile the CVS trunk.
439 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
441 * Renamed function silc_parse_nickname to silc_parse_userfqdn
442 to generally parse user@fqdn format strings. Affected file
443 lib/silcutil/silcutil.c.
445 * Added nickname_format and nickname_force_format fields to the
446 SilcClientParams structure. The first one defines the format
447 for the nicknames that the library will enforce if the receives
448 multiple same nicknames. The second one is boolean value and
449 can be used to force the library to always enforce the format
450 to the nicknames regardles whether there are multiple nicknames
451 or not. This configurable formatting was employed to flexibly
452 support accessing multiple nicknames from the user interface.
453 The userinterface can now set the nicknames to what ever format
454 they prefer. Affected file lib/silcclient/silcapi.h.
456 Added function silc_client_nickname_format to the file
457 lib/silcclient/idlist.c. It performs the nickname formatting.
459 Added new field `hostname´ to the SilcClientEntry context.
460 It holds the hostname of the client. Affected file is
461 lib/silcclient/idlist.h.
463 * Irssi SILC Client sets the nicknames in nick@hostn format.
464 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
465 irssi/src/silc/core/silc-core.c.
467 The WHOIS printing now also shows both the real nickname and
468 the formatted nickname so that user knows how to access the
469 user if there are multiple same nicknames cached. Affected
470 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
471 printing formatting too to take the hostname now as a separate
472 argument. The Affected file is
473 irssi/src/fe-common/silc/modules-formats.[ch].
475 * Changed the silc_client_get_clients_local to accept the formatted
476 nickname as argument. It accepts the real nickname too but the
477 formatted nickname can be used to find the true entry from
478 multiple entries. Affected file lib/silcclient/silcapi.h and
479 lib/silcclient/idlist.c.
481 * Added nickname_format_parse field to the SilcClientParams.
482 It is a callback function provided by the application to parse
483 the nickname out of the formatted nickname string. The library
484 calls it to get the nickname from the formatted string. Since
485 the application generally knows better the format of the nickname
486 string it parses it instead of the library, even though library
487 encodes the formatted string. If the callback function is not
488 provided then the library will use the string as is. The
489 affected file is lib/silcclient/silcapi.h.
491 * All the nickname strings passed to the client library in
492 commands are now expected to be formatted nickname strings.
493 If the command does not support the formatted nickname string
494 it will assume that the sent string is the actual nickname.
495 Affected file lib/silcclient/command.c.
497 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Added public key authentication support to OPER and SILCOPER
500 commands in the client library. Affected file is
501 lib/silcclient/command.c.
503 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Changed the get_auth_methdod client operation to be asynchronous.
506 It can be async if the application resolves the authentication
507 method from the server during the negotiation. Added new
508 SilcGetAuthMeth completion callback that the application will
509 call after resolving the authentication method.
511 Added function silc_client_request_authentication_method that
512 the application can use to resolve the authentication method
513 from the server. Added also SilcConnectionAuthRequest callback
514 that the library will call after the server has replied. The
515 application can call this function if it does not know the
516 current authentication method.
518 Affected files are lib/silcclient/client.c and
519 lib/silcclient/silcapi.h.
521 * The Irssi SILC client now automatically resolves the authentication
522 method incase any configuration information is not present (and
523 currently there never is). The affected file is
524 irssi/src/silc/core/client_ops.c.
526 * Fixed public key authentication from the client library.
527 Affected file lib/silcclient/protocol.c. Changed also the
528 protocol specification about the public key authentication in
529 the connection authentication protocol. The actual data to be
530 signed is now computed with a hash function before signing.
532 * Fixed the public key authentication from the server as well.
533 Affected file silcd/protocol.c.
535 * Removed the mlock()'s from the memory allocation routines.
536 Affected file lib/silcutil/silcmemory.c. The ./configure does
537 not check anymore for the mlock(). Affected file is
540 * Fixed USERS command in server to allow the execution of the
541 command for private and secret channels if the client sending
542 the command is on the channel. Affected file silcd/command.c.
544 * Fixed silc_client_get_clients_local to return the clients
545 count correctly. It could return wrong value. Affected file
546 lib/silcclient/idlist.c.
548 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
551 types. The assembler optimizations seemed not to like 64-bit
552 data types. The assmebler optimizations thus are now enabled
553 also for BSD systems as opposed to only enable them for Linux.
555 * Do not check for threads at all on BSD systems. Affected
556 file configure.in.pre.
558 * Removed -n and -h options from the Irssi SILC Client since
559 they are not used in silc.
561 * Fixed the prime generation to assure that the first digit
562 of the generated random number is not zero since our conversion
563 routines does not like number strings that starts with zero
564 digit. If zero digit is seen the random number is regenerated.
565 This caused some corrupted RSA keys when the zero first digit
566 was met. Affected file lib/silcmath/silcprimegen.c.
568 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
570 * Fixed WIN32 configuration in the ./configure script.
571 Fixed to include xti.h on environments that has it.
572 Patches by Carsten Ilchmann and andrew.
574 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
576 * Changed the silc_id_create_client_id to be collision
577 resistant. It is now assured that there cannot be created
578 two same client ID's. I suspect that some weird bugs in
579 the server were actually caused by duplicate Client IDs.
580 Affected file silcd/serverid.[ch]. A router receiving
581 new ID now also assures and informs the sending server
582 if the ID caused collision.
584 * Changed the silc_id_create_channel_id to also assure that
585 there are no collisions.
587 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
589 * Statement about ignoring the Mutual Authentication flag when
590 performing rekey with PFS was a bit misleading. It is ignored
591 if it was set in the initial negotiation, it cannot be even
592 set in the rekey. Fixed in the ke-auth draft. Started the
593 new versions of the protocol drafts in the doc/.
595 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
597 * Fixed a bug in silc_client_command_identify_save when saving
598 new channel information. The channel name was no duplicated
599 and caused crash on exit. Affected file is
600 lib/silcclient/command_reply.c.
602 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Fixed the getkey command handling in the server. Send just
605 empty OK reply to the sender if the key could not be fetched
606 (but everything else was ok, like the key just was not available).
607 Changed the public key parameter to optional in the protocol
608 specs so that empty OK reply can be sent. Affected file
611 Added a message to Irssi SILC client to tell to user if the
612 server did not return a public key.
614 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Fixed a channel key regeneration bug. It registered new
617 timeout tasks exponentially until all system resources were
618 used. Affected file silcd/server.c.
620 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
622 * Added the SILC Document generator to the scripts/silcdoc.
623 It can be used to generate the Toolkit Reference Manual out
624 of the source tree. Internally it will also use the RoboDoc
625 generator now imported in util/robodoc.
627 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Added couple of return's in rekey protocol if error orccurred
630 during the protocol. The execution must be terminated.
631 Affected file silcd/protocol.c. Also, terminate the protocol
634 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
636 * The client's Client ID was created initally from the wrong
637 nickname (it could have been in format nick@host) in the
638 silc_server_new_client. Affected file silcd/packet_receive.c
640 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
642 * Added some SILC_LOG_ERROR's to various error conditions
643 if client could not be added to ID cache. Affected files
644 silcd/packet_receive.c and silcd/server.c.
646 * When client's sock->user_data is freed, NULL also the
647 client->router and client->connection pointers. Added check
648 for these pointers being NULL to various places around the
649 code. Affected file silcd/server.c.
651 * Added client->data.registered == TRUE checks to various
652 places around the code to assure that unregistered client's
653 are not handled when it is not allowed. Affected file
656 * Added `bool registered' fields to all
657 silc_idlist_[server|client]_get_* routines to indicate whether
658 the fetched client needs to be registered or not. Affected
659 file silcd/idlist.[ch].
661 * Add your own entry as registered to the ID cache in the
662 server. Affected file server.c.
664 * Fixed a bug in silc_server_new_server. The SilcServer was
665 set as the new server's context instead of SilcServerEntry.
666 This naturally caused some weird bugs.
668 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
670 * Do not delete the channel rekey task when adding it
671 for in silc_server_create_channel_key.
673 * Changed the silc_server_create_channel_key to return
674 TRUE or FALSE to indicate the success of the channel key
677 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Fixed MSVC++ project files and added missing files to
680 Makefiles under win32/.
682 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Do not add TCP_NODELAY flag if the operating system
685 does not have it defined. Affected files are
686 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
688 * Fixed buffer overflow from Irssi SILC Client. Affected
689 file irssi/src/fe-common/core/themes.c.
691 * Fixed double free in client library in the file
692 lib/silcclient/client.c when disconnecting from server.
694 * Applied double free patch from cras to Irssi SILC client.
695 Affected files irssi/src/core/[modules/expandos].c
697 * Fixed the disconnection handling to Irssi SILC Client.
698 The application must call silc_client_close_connection
699 in ops->connect client operation in case of failure of
700 the connection. Affected file is
701 irssi/src/silc/core/client_ops.c.
703 * Do not set sock->protocol to NULL in the function
704 silc_client_close_connection after executing the protocol's
705 final callback since the sock might not be valid anymore.
706 Affected file lib/silcclient/client.c.
708 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Do not enable SILC_THREADS if the linking with libpthread
711 did not happen. Affected file configure.in.pre.
713 * Added notion to protocol specification that server must
714 verify the sent authentication payload with CMODE when
715 setting the channel founder key. Implemented it to the
716 server. Affected file silcd/command.c.
718 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Added _EXTRA_DIST SILC distribution variable to the
721 distributions file. It is used to conditionally add extra
722 files or directories to the specific distribution. Affected
723 files ./prepare, Makefile.am.pre and distributions.
725 Removed the `_' from the start of the distribution names.
728 * Added README.WIN32 for instructions to compile the Toolkit
731 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
733 * Fixed a double free in disconnection in the server. Affected
734 file is silcd/server.c.
736 * Fixed the lib/silcske/groups.c to work now also with GMP
737 MP library. The string conversion did not work when using
738 specific base and the base is indicated in the string as well.
740 * Created win32/ directory which now includes MSVC++ specific
741 stuff so that toolkit (DLLs) may be compiled with MSVC++.
742 It will appear only in the toolkit distribution
744 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Changed the key material distribution function in case when
747 the hash output is too short. The data is now concatenated
748 a bit differently than it used to. Made the change to the
749 SKE protocol specification.
751 * Added better GMP detection to configure.in.pre. A patch
754 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Fixed a minor bug in SKE that might cause some problem on
757 some platforms. Affected file lib/silcske/silcske.c.
759 * Added the cookie checking for initiator in the SKE. It checks
760 that the responder returns the sent cookie unmodified. The
761 affected file is lib/silcske/silcske.c. Added new SKE
762 error type INVALID_COOKIE that can be sent during the
763 negotiation. Fixed some memory leaks as well.
765 * Added the "invalid cookie" error message to Irssi SILC client's
768 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Added `task_max' field to the SilcClientParams to indicate
771 the maximum tasks the scheduler can handle. If set to zero,
772 default values are used. Affected file lib/silcclient/silcapi.h.
774 * Fixed memory leaks in silc_client_close_connection. Affected
775 file lib/silcclient/client.c.
777 * Added silc_client_del_client_entry to client library to free
778 all memory of given client entry. Affected file is
779 lib/silcclient/idlist.[ch].
781 * Added new functions silc_client_del_channel and
782 silc_client_del_server to delete channel and server entries.
783 Affected file lib/silcclient/[silcapi.h/idlist.c].
785 * Removed silc_client_del_client_by_id from silcapi.h.
787 * Fixed the INFO command to return the server's own info
788 correctly when querying by Server ID. Affected file is
791 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
793 * Removed the non-blocking settings in WIN32 code in the
794 silc_sock_[read/write] and added SleepEx instead. Affected
795 file lib/silcutil/win32/silcwin32sockconn.c. The availability
796 of input data is now checked with FIONREAD and ioctlsocket.
798 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
800 * Call silc_schedule_task_del_by_context in the
801 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
802 Affected file lib/silccore/silcprotocol.c.
804 * Call silc_protocol_cancel for active protocols in the
805 silc_server_close_connection if the funtion
806 silc_server_free_sock_user_data has not been called.
807 Affected file silcd/server.c.
809 * Generic tasks cannot be deleted using the del_by_fd
810 task deleting function since generic tasks does not match
811 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
813 * Added a notion to SILCOPER help file that the SILCOPER works
814 only on router server, not on normal server.
816 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Added for WIN32 support for the new scheduler as well.
819 Affected file lib/silcutil/win32/silcwin32schedule.c.
821 * Fixed the SHA1 implementation to work on various platforms.
823 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
825 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
826 API. It is part of the scheduler now. Everything else is
827 as previously but some functions has changed their names.
828 Checkout the lib/silcutil/silcschedule.h for the interface.
829 Updated all applications to use the new interface. Affected
830 files are lib/silcutil/silcschedule.[ch].
832 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Found a bug in the SKE implementation. The HASH value,
835 specified by the protocol, was not computed correctly. The
836 public key of the responder was not added to the computation
837 even though it is mandatory. Affected file lib/silcske/silcske.c.
838 This unfortunately causes incompatibilities with older
841 * Added WIN32 specific network init and uninit functions:
842 silc_net_win32_init and silc_net_win32_uninit to init and uninit
843 the Winsock2. Affected file lib/silcutil/silcnet.h and
844 lib/silcutil/win32/silcwin32net.c.
846 * Set the socket always to nonblocking mode on WIN32 after
847 reading data or writing data. Affected file is
848 lib/silcutil/win32/silcwin32sockconn.c.
850 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
852 * Fixed various compilation problems under WIN32. Affected
853 files lib/silcutil/win32/silcwin32thread.c and
854 lib/silcutil/win32/silcwin32schedule.c.
856 * Removed all _internal.h #includes from public header
857 files. Internal headers must never be included from
860 Removed also the lib/silcske/payload_internal.h file.
862 * All include files that may be needed (public and some others
863 included by the public headers) by application developers are
864 now copied to the ./includes directory. It does not copy any
865 internal headers. Affected file Makefile.defines.pre and all
866 Makefile.am's under lib/ and subdirs.
868 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Do not change the ~/.silc directory's permissions automatically.
871 Affected file irssi/src/silc/core/clientutil.c.
873 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
875 * Do not cancel the protocol in silc_server_close_connection
876 it might cause recursion. Now cancelled in the function
877 silc_server_free_sock_user_data. Affected file silcd/server.c.
879 * Fixed the silc_server_remove_clients_by_server to regenerate
880 the channel keys correctly finally. Added also new function
881 silc_server_remove_clients_channels to actually do it.
882 Affected file silcd/server.c.
884 * Fixed the silc_server_new_channel to not crash by giving
885 wrong router to the new channel. Affected file is
886 silcd/packet_receive.c.
888 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
891 which is given as argument to the silc_client_alloc now.
892 It can be used to configure the client and set various parameters
893 that affect the function of the client.
895 * The USERS command in server did not check whether the channel
896 is private or secret. Affected file silcd/command.c.
898 * Added new argument to the USERS command in protocol specification.
899 The USERS command now can take the channel name as argument
900 as well. Added support for this in client and server and
901 updated the protocol specs.
903 * Completed the GETKEY command in client. It can be now used
904 to fetch also servers public key not only some clients.
905 Affected files lib/silcclient/command[_reply].c.
907 * Added silc_client_get_server to return server entry by the
908 server name. Affected files lib/silcclient/silcapi.h and
911 * Redefined the IDENTIFY command in protocol specification to be
912 more generic. It now can be used to query information about
913 any entity in the SILC Network, including clients, servers and
914 channels. The query may be based either the entity's name
915 or the ID. Added support for this in both client and server.
917 Affected files silcd/command.c and lib/silcclient/command.c
920 * Optimized the WHOIS and WHOWAS commands in the server. Removed
921 the _from_client and _from_server functions. Affected file
924 * Added silc_client_get_channel_by_id_resolve to the file
925 lib/silcclient/silcapi.h to resolve channel information by
926 its ID. Added also silc_client_get_channel_by_id that
927 does not resolve it from the server.
929 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Added SilcServerEntry context into the client library
932 to represent one server. The INFO command now allocates
933 these to save the resolved server info. For now on the
934 client library will also keep information about servers,
935 connected and resolved with INFO.
937 The INFO command now allocates the SilcServerEntry context
938 and saves the server info there. The COMMAND_REPLY in
939 the INFO now returns the parameters to application in
940 same order as defined in the protocol specification.
942 The entries are cached in the client->server_cache.
944 * The INFO command is now issued after received the Client ID
945 from the server. Affected file lib/silcclient/client.c.
947 * The CMODE_CHANGE notify may now return also an SilcServerEntry
948 to the application as the mode changer might be server.
949 It is guaranteed that NULL is not returned anymore to the
950 application. Affected file lib/silcclient/client_notify.c.
952 The ID Type is now also passed to the application so that
953 it can check whether the returned entry is SilcClientEntry
956 Added new function silc_client_get_server_by_id to return
957 the server entry by ID. Affected files are the
958 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
960 * Do not create the channel in the Irssi SILC Client when issuing
961 the JOIN command but when received the sucessful JOIN command
962 reply. Otherwise the channel might get created even though we
963 could not join it. The Affected file is
964 irssi/src/silc/core/[silc-channels.c/client_ops.c].
966 * Fixed a channel joining bug in router. The router must also
967 check the channel modes, invite and ban lists etc. when serving
968 the JOIN command sent by normal server. Affected file is
969 silcd/command.c. The router now resolves the client's
970 information from the server who sent the JOIN command if it
971 does not know it, and processes the JOIN command only after
974 * Changed the SilcCommandCb to take new argument; void *context2.
975 Affected file lib/silccore/silccommand.h
977 The second argument in the command callbacks in the server now
978 includes the SilcServerCommandReplyContext if the command was
979 called as pending command callback from the command reply.
980 Otherwise it is NULL. When called as pending the status of the
981 command reply will be checked and if it was erronous the
982 error will be sent to the original sender of the command.
983 This way the client always receives the error messages even
984 though the server was actually the one who received the error
985 when it resent the command to router, for example. Affected
986 files silcd/command[_reply].[ch].
988 * Fixed sending WHOWAS command's error message to client if
989 the requested client could not be found. It was missing.
992 * Changed the CMODE and CUMODE commands reply arguments in the
993 protocol specification. The Channel ID is now sent in both
994 of the commands to identify the channel. Implemented this
995 new feature to the client and server. Affected files
996 lib/silcclient/command_reply.c and silcd/command.c.
998 * Made better checks for invite and ban lists in the JOIN
999 command in server. Affected file silcd/command.c.
1001 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * The server now performs the incoming host IP/DNS lookup
1004 using the silc_socket_host_lookup and thus does not block
1005 the server anymore. Affected file silcd/server.c.
1007 * Completed the multi-thread support for SILC Scheduler in
1008 the lib/silcutil/silcschedule.c.
1010 * Fixed the configure.in.pre to detect the pthread correctly
1013 * Fixed a deadlock in silc_task_queue_wakeup in the file
1014 lib/silcutil/silctask.c.
1016 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Added new function silc_schedule_wakeup that is used in
1019 multi-threaded environment to wakeup the main thread's
1020 schduler. It needs to be used when a thread adds a new task
1021 or removes a task from task queues. After waking up, the
1022 scheduler will detect the task queue changes. If threads
1023 support is not compiled in this function has no effect.
1024 Implemented the wakeup mechanism to both Unix and WIN32
1025 systems. Affected files are lib/silcutil/silcschedule.[ch],
1026 lib/silcutil/unix/silcunixschedule.c and the
1027 lib/silcutil/win32/silcwin32schedule.c.
1029 * Added new function silc_task_queue_wakeup to wakeup the
1030 scheduler by the specified task queue. Affected file
1031 lib/silcutil/silctask.[ch].
1033 * The silc_socket_host_lookup_start now wakes up the scheduler
1034 after adding the timeout task. Affected file is
1035 lib/silcutil/silcsockconn.c.
1037 * The silc_socket_host_lookup is synchronous now if the threads
1038 support is not compiled in. However, the callback is still
1039 called asyncronously through the scheduler, anyway. Affected
1040 file lib/silcutil/silcsockconn.c.
1042 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Added new function silc_socket_host_lookup to perform
1045 asynchronous IP and FQDN lookups for the socket connection.
1046 Affected files lib/silcutil/silcsockconn.[ch].
1048 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1051 that may or may not compile the mutex support in.
1053 Changed the silc_mutex_alloc interface. It allocates the
1054 mutex now to the sent pointer and returns TRUE or FALSE.
1056 Affected file lib/silcutil/silcmutex.h.
1058 * Wrote the SILC Task Queue interface to support multi-threads.
1059 Affected file lib/silcutil/silctask.[ch].
1061 * Wrote the SILC Scheduler to support multi-threads. Affected
1062 file lib/silcutil/silcschedule.c.
1064 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1067 in lib/silcutil/win32/.
1069 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Defined SILC Mutex API and SILC Thread API and implemented
1072 them for Unix. Affected files are
1073 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1074 lib/silcutil/unix/silcunixmutex.c and
1075 lib/silcutil/unix/silcunixthread.c.
1077 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Fixed the silc_server_remove_clients_by_server's channel
1080 key re-generation. The hash table handling was incorrect
1081 and would not work with many channels. Affected file is
1084 * Fixed some memory leaks around the server code.
1086 * Rewrote the silc_server_get_users_on_channel to support IPv6
1087 based Client ID's. Affected file silcd/server.c.
1089 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1090 specification. However, a separate document must be written
1091 to define the detailed signing procedure and the payload
1092 associated with the flag. Defined the flag to the
1093 lib/silccore/silcchannel.h as well.
1095 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * Changed the dynamic tables to static size tables in the
1098 lib/silccrypt/silchmac.c.
1100 * Removed GCC dependencies from the code. A patch by cras.
1102 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Do not show the error "Error receiving packet bla bla"
1105 in server if it really was not an error (-2 means that reading
1106 is pending). Affected file silcd/server.c.
1108 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1110 * Fixed a possible crash in silc_server_remove_clients_by_server
1111 in silcd/server.c. Fixed there also some memory leaks.
1113 * Fixed the silc_idlist_replace_client_id. It could replace
1114 wrong key in the hash table. Affected file silcd/idlist.c.
1116 * Do not check whether there are global users on the channel
1117 if the channel->global_users is FALSE. Affected functions
1118 silc_server_remove_from_one_channel and
1119 silc_server_remove_from_channels in silcd/server.c. Also,
1120 do not check if the removed client is local as we can be
1121 sure that global client was not removed from the channel
1122 and checking for global users is not needed.
1124 * The silc_server_remove_clients_by_server now re-generates
1125 the channel keys correctly for those channels that had
1126 clients removed from them. Affected file silcd/server.c.
1128 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Found the reason of random crashes in the server. We weren't
1131 ignoring the SIGPIPE signal (which can be sent in write())
1132 and it crashed the server. Affected file silcd/silcd.c.
1134 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1136 * Assure that sock->user_data is not NULL in the function
1137 silc_server_packet_send in silcd/packet_send.c.
1139 * Disconnect the remote connection if it could not be added
1140 to any ID lists in the server. The affected file is
1143 * Check in silc_server_packet_send[_real/dest] that the
1144 socket is not disconnecting and ignore the data if it is.
1145 Affected file silcd/packet_send.c.
1147 * Define inline to __inline on native WIN32 compilation.
1148 Affected file includes/silcwin32.h.
1150 * Added some explicit type casts for inline code since MSVC
1151 require them. Affected files lib/silcutil/silcbuffer.h,
1152 lib/trq/silcdlist.h and lib/trq/silclist.h.
1154 * Print warning in log files from now on if the packet
1155 decryption fails. Affected file silcd/server.c.
1157 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1159 * Changed the `say' client operation's interface to accept
1160 new `type' argument to indicate the type of the message sent
1161 by the library. The application may filter the library's
1162 messages according the type. The affected file is the
1163 lib/silcclient/silcapi.h.
1165 * Added two new functions to lib/silcclient/silcapi.h:
1166 silc_client_del_client and silc_client_del_client_by_id.
1167 Affected file lib/silcclient/idlist.c.
1169 * Moved the clientincludes.h from includes/ to silc/ and
1170 serverincludes.h from includes/ to silcd/.
1172 * The modes for the CMODE and CUMODE are now passed as
1173 uint32 for application with COMMAND_REPLY. The affected
1174 file is lib/silcclient/command_reply.c.
1176 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * /WHOIS without arguments shows client's own information.
1179 Affected file lib/silcclient/command.c.
1181 * Changed PING to not accept any arguments. The specs
1182 says that client can ping only the connected server so
1183 requiring an argument is not needed. Affected file is
1184 lib/silcclient/command.c.
1186 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Fixed a fatal bug in private message sending and reception
1189 encryption and decryption when using private message keys.
1190 The implementation was incorrect and did not follow the
1191 specification. It causd that some of the message were
1192 lost since it did not use the sending and receiving keys
1193 as the protocol suggests. This has been fixed and will cause
1194 incompatibilities with older clients when sending private
1195 message encrypted with private message keys. Affected files
1196 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1197 and various other in Irssi SILC Client.
1199 Added `responder' boolean argument to the functions
1200 silc_client_add_private_message_key[_ske] to indicate when
1201 the key is added as responder or initiator of the key
1204 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Removed the silc_ske_check_version function and created
1207 a SilcSKECheckVersion callback. Added also a function
1208 silc_ske_set_callbacks that is now used to set all SKE
1209 callbacks. The callback functions are not given to
1210 the SKE functions anymore, but this function is used to
1213 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1215 * Added `silc_version' argument to the silc_client_alloc
1216 to define the version of the application for the library.
1217 The library will use the version string to compare it
1218 against the remote host's (usually a server) version
1219 string. Affected file lib/silcclient/silcapi.h
1221 * Added the KE protocol context to Key Agreement context
1222 in client library so that we can abort the SKE if it
1223 is in process when we get timeout. Affected file is
1224 lib/silcclient/client_keyagr.c.
1226 * Do not resolve the client ID forever if it returns in the
1227 first time that such client does not exist. This was done
1228 for example with private message. Affected file is
1229 lib/silcclient/client_prvmsg.c.
1231 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Do not add regex.h for WIN32. The affected file
1234 includes/silcincludes.h.
1236 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1237 not work yet 100%. It generates the DLL's automatically
1238 when compiling with --with-win32 under cygwin.
1240 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1242 * lib/contrib/regex.c is not compiled on WIN32.
1244 * Added silc_net_get_socket_opt function to the
1245 lib/silcutil/silcnet.h.
1247 * Added includes/silcwin32.h for WIN32 specific includes
1250 * Do not use ptime structure or any of the posix process
1251 functions on WIN32 in lib/silccrypt/silrng.c.
1253 * Added silc_gettimeofday to provide generic function
1254 for struct timeval on all platforms. Added the function
1255 to lib/silcutil/silcutil.h.
1257 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1260 library as they clearly belong there. As a plus side we
1261 can make the actual socket connection routines platform
1264 Added also new generic function silc_socket_read and
1265 silc_socket_write (that used to be silc_packet_[read/write].
1266 The implementation of these are platform specific.
1268 * Added WIN32 specific routines of silc_socket_[read/write]
1269 to lib/silcutil/win32/silcwin32sockconn.c.
1271 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Added preliminary support for native WIN32 compilation under
1274 cygwin (using the -mno-cygwin option for GCC) to the
1275 ./configure.in.pre. The --with-win32 now prepares the
1276 compilation for native WIN32.
1278 * Rewrote the SILC Scheduler interface in the file
1279 lib/silcutil/silcschedule.h. The scheduler is now context
1280 based and does not have anymore any global static scheduler.
1281 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1282 and created lib/silcutil/win32 directory for WIN32 based
1285 * Added Unix specific network routines to the
1286 lib/silcutil/unix/silcunixnet.c and the old
1287 lib/silcutil/silcnet.c includes now only generic routines.
1289 Added WIN32 specific network routines to the
1290 lib/silcutil/win32/silcwin32net.c.
1292 * Added Unix specific utility functions from the
1293 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1295 * Added WIN32 SILC Scheduler to the file
1296 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1299 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Do not handle JOIN notify in the server if the target client
1302 is not registered (idata->registered == FALSE). The affected
1303 file is silcd/packet_receive.c.
1305 * Update the nickrec->founder in event_cumode in the Irssi SILC
1306 client. Affected file irssi/src/silc/core/silc-channels.c.
1308 * Fixed the CUMODE_CHANGE notify handling in the server when
1309 server and router are announcing their clients on channels.
1310 Now the mode changes are saved and notified correctly. The
1311 affected file is /silcd/packet_receive.c.
1313 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1314 They really did not replace the cache entry in the ID Cache.
1315 Now they do that. Affected file silcd/idlist.c.
1317 * Fixed the KICK notify handling in the Irssi SILC client to
1318 update the channel records so that the kicked client does not
1319 appear to be on the channel. The affected file is
1320 irssi/src/silc/core/silc-channels.c.
1322 * Always update the conn->current_channel when executing command
1323 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1325 * Fixed the KILL notify handling in Irssi SILC client to remove
1326 the killed client on all channels.
1328 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * Fixed the silc_parse_command_line to remove extra spaces
1331 from the start and end of the arguments. Affected file is
1332 lib/silcutil/silcutil.c.
1334 * Cancel and free any active protocol in the function
1335 silc_server_close_connection. Affected file silcd/server.c.
1337 * Cancel and free any active protocol in the function
1338 silc_client_close_connction. Affected file is
1339 lib/silcclient/client.c.
1341 * Do not execute the KILL command for clients that are in
1342 history (ie. they are not in the network). Affected file is
1345 * Fixed KILL notify handling, client does not crash anymore.
1346 Affected file irssi/src/silc/core/silc-channels.c.
1348 * Reduced the default packet buffer size from 2048 to 1024 in
1349 lib/silccore/silcpacket.c.
1351 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1352 counter to the SKE context that is incresed when the SKE library
1353 performs async operation outside the library. If the outside
1354 process frees the SKE context and FREED status will be set
1355 and the library will detect after the sync operation that the
1356 libary is freed. The affected files are
1357 lib/silcske/silcske[_status].[ch].
1359 * Resolve the client entry information in the function
1360 silc_client_channel_message to assure that NULL pointer is not
1361 passed as client entry to the application. */
1363 * Fixed the task timeout calculation to assure that there is
1364 never negative timeouts. The affected file is
1365 lib/silcutil/silcschedule.c.
1367 * Fixed the channel user mode notification sending in server.
1368 It was sent point-to-point to the router (or to server by router)
1369 but it needs to be destined to a channel. The routines now
1370 supports sending the channel user mode notifys to the channels
1371 when announcing clients and channels. Affected files are
1372 silcd/server.c and silcd/packet_receive.c.
1374 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1375 It did not actually replace the old channel entry in the cache.
1376 Affected file lib/silcclient/client_notify.c.
1378 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Fixed a possible crash in silc_packet_send_prepare. It now
1381 assures always that there is enough space in the buffer and
1382 at the tail area of the buffer (for MAC).
1384 Fixed the inbound buffer reallocation in silc_packet_read.
1385 It was old code and did not handle the reallocation correctly.
1388 The affected file is lib/silccore/silcpacket.c.
1390 * Fixed buffer overflow in silc_parse_nickname in the file
1391 lib/silcutil/silcutil.c.
1393 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * make install generates new server keys only if there is not
1398 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1400 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1401 Added check that if the NOREPLY is set then we will not send
1402 the away message. This avoids infinite loop of away messages
1403 if both clients are away. The affected file is
1404 lib/silcclient/client_prvmsg.c.
1406 * Fixed client crash if /NICK was given without arguments.
1407 Affected file lib/silcclient/command.c.
1409 * Server does not send the invite list in INVITE command back
1410 to the client if the list was not altered. Added this notion
1411 to the protocol spec as well. Affected file silcd/command.c.
1413 Fixed possible crash in INVITE command by checking the
1414 value of silc_server_get_client_route command.
1416 * Fixed the INVITE notify type handling. The arguments are now
1417 taken in correct order and client does not crash. The affected
1418 file is irssi/src/silc/core/silc-channels.c.
1420 Removed the "Inviting xxx to channel" message from the
1421 client library away and let the application handle it.
1422 Affected file lib/silcclient/command.c. Added that message
1423 to Irssi SILC client's message formats.
1425 * Fixed CMODE command crash in client. It now checks the
1426 amount of arguments correctly and does not crash. The affected
1427 file is lib/silcclient/command.c.
1429 * Do not create new channel automatically in silc_channels_join
1430 but check whether the channel by that name already exists.
1431 Affected file irssi/silc/core/silc-channels.c.
1433 * Do not send the SERVER_SIGNOFF to router if the disconnected
1434 entity was the router. Affected file silcd/server.c.
1436 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1437 SILC client as it was missing from there.
1439 Added the handling of the KICK notify to the Irssi SILC client
1440 as it was missing. Added "you have been kicked" message to
1441 Irssi SILC client's message modules formats.
1443 Added the handing of the KILL notify to the Irssi SILC client
1444 as it was missing. Added the kill message module formats
1447 The affected file is irssi/src/silc/core/silc-channels.c.
1449 * The router did not save the channel mode the server announced.
1450 Affected file silcd/packet_receive.c.
1452 * Fixed a possible crash in INFO command in server. If the
1453 server did not provide the server info it crashed. Affected
1454 file silcd/command.c.
1456 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Fixed the GETKEY command in the server to check also the
1459 global list. Otherwise the GETKEY would not work correctly
1460 in normal SILC server. Affected file silcd/command.c.
1462 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1464 * Fixed GETKEY crash, it crashed if the command did not succseed.
1466 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1469 is now real and not just an macro interface to GMP.
1471 Removed the entire GMP from the source tree and imported new
1472 NSS MPI library instead. Reason for removing GMP is that it is
1473 extremely large and compiles extremely slow. The NSS MPI
1474 is only a few files and compiles in less than 10 seconds.
1475 The speed is also about the same as GMP. The MPI is imported
1476 to lib/silcmath/mpi.
1478 If the system has GMP installed we will still use the GMP.
1479 If it is not then the NSS MPI will be compiled.
1481 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Merged a long nickname (127 characters long) crash bugfix from
1484 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1486 * Merged a freed memory reference bugfix from Irssi CVS tree.
1487 Affected file irssi/src/core/commands.c.
1489 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Added the server's public key sving and verification to the
1492 server when performing the SKE. This was missing and the
1493 remote server's (or router's) public key was accepted without
1494 checking whether we have it previously or trust it at all.
1495 Affected file silcd/protocol.c.
1497 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Check in the silc_server_timeout_remote if protocol is active
1500 and make sure that the protocol's final callback is called so
1501 that all memory if freed. Affected file silcd/server.c.
1503 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1505 * silc_server_whois_send_reply crashed the server if the nickname
1506 was 127 characters long. Affected file silcd/command.c.
1508 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Added sanity check to the silc_server_new_client. If the hostname
1511 is provided inside username then check that the provided hostname
1512 really is the same as the resolved one. If the hostname was not
1513 resolved then check it from the public key. Affected file is
1514 silcd/packet_receive.c.
1516 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1517 if the server disconnected us and the connection is not valid
1518 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1520 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1521 the library to the lib/silcutil/silcutil.[ch].
1523 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Close log file after open. Affected file
1526 lib/silcutil/silclog.c.
1528 * Check whether sock == NULL in silc_client_send_packet and return
1529 if it is. Affected file lib/silcclient/silcclient.c.
1531 * Check rec->entry == NULL in the Irssi SILC Client before
1532 sending the channel message. Affecte file is
1533 irssi/src/silc/core/silc-servers.c.
1535 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Merged a splitted window bugfix from Irssi CVS tree. The
1538 affected file is irssi/src/fe-text/textbuffer-view.c.
1540 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1541 It did not print nickname.
1543 * Improved the distributions system a bit.
1545 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1548 irssi/src/fe-text/gui-window.c.
1550 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1551 to in-active server. The affected file is
1552 irssi/src/silc/core/client_ops.c.
1554 * Resolve the client in USERS command reply if the entry does
1555 not have username resolved. The affected file is
1556 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1557 command to WHOIS command to really resolve stuff. The USERS
1558 is not used any more in any critical section so WHOIS can
1559 be used even though it might be slower than IDENTIFY.
1561 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1564 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Changed the protocol API a bit more consistent in the
1567 lib/silccore/silcprotocol.[ch].
1569 * Changed the following headers to ROBODoc format:
1571 lib/silccore/silcpayload.h
1572 lib/silccore/silcprotocol.h
1573 lib/silccore/silcsockconn.h
1575 All core library headers are now formatted.
1577 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Fixed a bug in Irssi SILC client; do not show that you are
1580 server/router operator if you really are not. Affected file is
1581 irssi/src/silc/core/client_ops.c.
1583 * Renamed silc_command_free_payload to silc_command_payload_free.
1584 Affected file lib/silccore/silccommand.h
1586 * Added silcmath.h to include the prototoypes of various routines
1587 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1590 * Changed the following headers to ROBODoc format:
1592 lib/silccore/silcchannel.h
1593 lib/silccore/silccommand.h
1594 lib/silccore/silcid.h
1595 lib/silccore/silcidcache.h
1596 lib/silccore/silcmode.h
1597 lib/silccore/silcnotify.h
1598 lib/silccore/silcpacket.h
1599 lib/silcmath/silcmath.h
1601 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Added checking to the server code not to start the server if
1604 ciphers and stuff are not configured properly. Affected files
1605 silcd/serverconfig.[h] and silcd/server.c.
1607 * Changed the layout of the header files of the public interfaces
1608 in the SILC libraries. The new layout supports ROBODoc
1609 documentation tool (and some others) so that it is easy to create
1610 a library reference manual. All the other headers and source
1611 code must still follow the CodingStyle document. Also source
1612 code must not include these ROBODoc stuffs, only the headers.
1613 Furthermore, all public interface headers must now be named
1614 by using `silc' prefix, example: silcapi.h, silccipher.h.
1615 Some files were renamed due to this. All the other headers
1616 must not be used as public interfaces. I will update the
1617 CodingStyle document later. Changed following headers, so far:
1619 lib/silcclient/silcapi.h

1624 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Removed silc_client_packet_send_flush from the client library
1629 as it is not needed. Affected file lib/silcclient/client.[ch].
1631 * Added printing of message of unresolved authentication method
1632 to the Irssi SILC client. Added it to the module formats.
1633 Removed the same message from the client library.
1635 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1637 * Added new distribution feature, DISTLABEL. Every distribution
1638 can define own preprocessor label that can be used in the
1639 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1640 file distributions, acconfig.h.pre and prepare.
1642 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Added Makefile.defines_int to include the actual definitions
1645 for Makefile.defines.in. Tested the new distribution system,
1646 created distributions and tested installation.
1648 * Added AWAY message printing to the Irssi SILC client. Added
1649 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1651 * Added SCONNECT command to call the SILC's CONNECT command.
1652 Cannot use CONNECT directly since Irssi uses that internally.
1653 Affected file irssi/src/silc/core/silc-servers.c.
1655 Added ACTION local command. It is same as ME command but takes
1656 the channel as mandatory argument.
1658 Rewrote some of the Irssi's help files to suite for SILC
1661 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Added Makefile.defines[.in] that should for now on be included
1664 in all Makefile.am file in the source tree. That file includes
1665 all common compilation definitions for SILC source tree.
1667 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Minor changes to the ./prepare script to change the package
1670 name according the distribution name to the configure.in.
1672 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Created new distribution system. Added file `distributions'
1675 that defines all the distributions that can be created out of
1676 the SILC source tree. The ./prepare script now reads that
1677 file to determine how to prepare the distributions. The
1678 first argument to the ./prepare is the name of the distribution
1679 and second is the version of the distribution. If given
1680 without arguments it creates the default (toolkit) distribution
1681 with the default version (defined in ./prepare).
1683 All Makefile.am files that are subject to the distributions
1684 are now named as Makefile.am.pre. These are ./Makefile.am
1685 and lib/Makefile.am. Others may be changed later.
1687 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Added invite list, ban list, some key management and connection
1690 error message printing to module formats in the Irssi SILC client.
1692 * Added new silc_client_set_away_message to set the away message
1693 that is back to the person who sent private message. The
1694 affected file lib/silcclient/silcapi.h and the
1695 lib/silcclient/client_prvmsg.c.
1697 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * Fixed the private message sending in the Irssi SILC client,
1700 added local command KEY to the Irssi SILC client.
1702 Added key management and key agreement message formats to the
1703 irssi/src/fe-common/silc/module-formats.[ch].
1705 Added USERS (alias WHO) printing, server/router operator
1706 indication and LIST command printing to the module formats.
1708 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Fixed channel joining notify handling, cumode notify handling
1711 from Irssi SILC client.
1713 * Added SILC specific module-formats to the Irssi SILC client so
1714 that SILC specific message hilighting, colors etc is possible.
1715 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1717 Added channel mode, channel user mode, actions, notices,
1718 whois and whowas printing to the the module-formats.c.
1720 * Fixed a bug in channel deletion in the server. The channel
1721 is not left to the cache even if the channel founder auth mode
1722 is set when there are no users anymore on the channel. Affected
1723 file silcd/server.c.
1725 * The silc_net_localhost now resolves the entire hostname including
1726 the domain name. Affected file lib/silcutil/silcnet.c.
1728 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Changed the ask_passphrase client operation to be ascynchronous.
1731 It has now a completion callback and a context that the
1732 application must call after it has got the passphrase from
1733 the user. Affected files lib/silcclient/silcapi.h,
1734 lib/silcclient/protocol.c, lib/silcclient/command.c and
1737 Added SilcAskPassphrase callback that the application calls
1738 to deliver the passphrase to the library.
1740 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1741 The public key verification and especially a certificate
1742 verification is asynchronous procedure.
1744 Added new SILC_SKE_STATUS_PENDING status to indicate the
1745 request is pending and a callback will be called to finalize
1748 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1749 indicate that remote end did not send its public key (or
1750 certificate), even though we require it. Added check for this
1751 condition in the SKE. This was a security bug, now fixed.
1753 Defined new SilcSKEVerifyCbCompletion callback that is called
1754 when the verification process is completed.
1756 The affected files lib/silcske/silcske_status.h and
1757 lib/silcske/silcske.[ch].
1759 * Changed the verify_public_key client operation to be async
1760 as well. Defined SilcVerifyPublicKey callback that is used to
1761 indicate the success of the public key verification process.
1763 Changed the server and client to use the new async client
1766 * Changed the Irssi SILC client's internal scheduler to be called
1767 twice as many times as it used to be. As a result the client
1768 should be a bit faster now. Affected file is
1769 irssi/src/silc/core/silc-core.c.
1771 * Added support to Irssi SILC client of asynchronous public key
1772 verification and passphrase inquiry. Affected file is
1773 irssi/src/silc/core/silc-core.c.
1775 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Do not say "You have left channel %s" in client library.
1778 Moved it to the application. Affected files are
1779 lib/silcclient/command.c and silc/client_ops.c.
1781 * Fixed silc_client_get_clients. Command context was not
1782 duplicated and was freed memory in the callback. Affected
1783 file lib/silcclient/idlist.c.
1785 * Do not say "you are now talking..." on JOIN command in the
1786 client library. The appliation must handle it.
1788 * Do not say ".. changed topic to" in command reply in the
1789 client libary. The application must handle it.
1791 * Fixed TOPIC command sending in the client library.
1793 * Fixed a memory leak in silc_client_command_free in the file
1794 lib/silcclient/command.c.
1796 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Imported a modified version of Irssi client to the source tree.
1799 The Irssi will be used to create a new client called
1800 Irssi SILC. Imported to irssi/.
1802 Added silc_core_init_finish function to the Irssi. Affected
1803 file irssi/configure.in.
1805 A lot changes in the Makefile.ams around the irssi tree.
1807 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Do not rehash if the new size is same as the old size of the
1810 hash table, in the silc_hash_table_rehash*. The affected file
1811 lib/silcutil/silchashtable.c.
1813 * Replaced hash_table_del_by_context calls from the server
1814 (when channel->user_list and client->channels) to the
1815 hash_table_del as it is sufficient and faster.
1817 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Added silc_hash_table_list, silc_hash_table_get and the
1820 SilcHashTableList structure to provide an alternative way to
1821 traverse the hash table. The affected files are
1822 lib/silcutil/silchashtable.[ch].
1824 * Changed the server's idlist routines to use the hash table
1825 routines to optimize the code.
1827 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Replaced the client entry's `channel' list and channel entry's
1830 `user_list' list to hash tables for optimized lookup. Changed
1831 the code to use the hash table interface around the code.
1832 Affected file lib/silcd/idlist.[ch].
1834 * Added `auto_rehash' boolean argument to the function
1835 silc_hash_table_alloc to indicate whether the hash table should
1836 auto-rehash when it thinks is appropriate time. It will
1837 increase the hash table size if the there is twice as much
1838 entries in the table than the size of the table, and will
1839 decrease the size if there are twice as less entries than
1840 the size of the table.
1842 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1846 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * silc_idcache_purge_by_context deletes the entry now by context
1849 as it is supposed to do. Affected file lib/silccore/idcache.c.
1851 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1852 client is not anymore valid (WHOWAS givens the info) and not
1853 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1855 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Removed the `data' and `data_len' arguments from the ID Cache
1858 interfaces and added `name' argument. ID Cache does not handle
1859 anymore the binary data only a names associated with given ID.
1861 * When hashing a Client ID with silc_hash_id the entire ID is
1862 not hashed anymore, instead only the hash of the Client ID is
1863 hashed. This way we can access the Client ID from the cache
1864 with Client ID but with the hash of the ID (which is a hash of
1865 the nickname) as well without any difference in performance.
1867 Added also silc_idcache_find_by_id_one_ext to do one on one
1868 searching when we have the actual ID. Added also function
1869 silc_hash_client_id_compare. The affected files are
1870 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1872 * When hashing the name associated with a ID it is always done
1873 in lowercase. This way we can access the cache without worrying
1874 about case-sensitivity, even though, for example nicknames are
1877 * Fixed a bug in server with channel message sending. It put
1878 wrong ID type as destination ID. The affected file
1879 silcd/packet_send.c.
1881 * silc_idcache_del_by_context now deletes from all hash tables
1882 by context. Affected file lib/silccore/idcache.c.
1884 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Changed the client library to use the new ID Cache interface.
1887 Changes around the source tree.
1889 * Added silc_hash_table_rehash_ext to rehash with specific
1890 hash function. Affected file lib/silcutil/silchashtable.[ch].
1892 * Added silc_hash_string_compare to compare two strings in the
1893 hash table. Affected file lib/silcutil/silcutil.[ch].
1895 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added new function silc_idcache_del_by_context into the
1898 lib/silccore/idcache.[ch].
1900 * Changed the server's ID list routines to use the new ID Cache
1901 interface. Changes around the source tree.
1903 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Added silc_hash_table_del[_by_context]_ext functions in to the
1906 lib/silcutil/silchashtable.[ch].
1908 Removed silc_hash_table_find_all* routines and added new
1909 silc_hash_table_find_foreach to replace them.
1911 Added silc_hash_table_replace_ext function as extended
1912 replacing function. Separated the simple hash table interface
1913 from the extended hash table interface in the file
1914 lib/silcutil/silchashtable.h.
1916 * Fixed minor bugs and changed it to use some of the new
1917 hash table functions in lib/silccore/idcache.c
1919 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Added new function silc_hash_table_find_all to return all keys
1922 in the hash table by the specified key. As the hash table is
1923 collision resistant it also makes it possible to have several
1924 duplicate keys in the hash table. This function may be used to
1925 find all of the keys from the hash.
1927 Added user_context arguments to the SilcHashFunction,
1928 SilcHashCompare and SilcHashDestructor to deliver user specified
1931 Added new fuctions silc_hash_table_find[_all]_ext to do
1932 extended lookup with specified hash and compare functions and
1933 specified user contexts.
1935 Added new function silc_hash_table_add_ext to add the key
1936 with specified hash function and user context.
1938 Added new function silc_hash_table_foreach to traverse all
1939 entrys in the hash table. Added SilcHashForeach callback
1942 Added new function silc_hash_table_del_by_context to delete
1943 the entry only if the context associated with the key matches.
1945 Affected files are lib/silcutil/silchashtable.[ch].
1947 * Removed silc_hash_[server/client/channel]_id and added just
1948 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1949 silc_hash_id_compare to compare two ID's using as the hash table
1950 comparison function. Added also silc_hash_data to hash
1951 binary data and silc_hash_data_compare to compare it.
1953 * Removed silc_idlist_find_client_by_hash as it is not needed
1954 anymore. Affected file silcd/idlist.[ch].
1956 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1957 to use internally the SilcHashTable. The new ID Cache is a lot
1958 faster than the old one. Some of the ID Cache interface was also
1959 rewritten and obsolete and stupid functions were removed.
1961 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added entry_count field to the SilcHashTable to keep the number
1964 of the entries in the table. Implemented the function
1965 silc_hash_table_rehash. Added new function
1966 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1968 Fixed a minor bug in silc_hash_table_free.
1970 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1971 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1972 into the lib/silcutil/silcutil.[ch].
1974 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Implemented a collision resistant hash table into the
1977 lib/silcutil/silchashtable[ch]. See the header and the source
1978 for the SilcHashTable API.
1980 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Merged dotconf version 1.0.2 into lib/dotconf.
1984 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Do not compile anything in lib/silcsim/* if the SIM support
1987 is not enabled. The tree should now compile without problems
1990 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Compiled the SILC under cygwin. Compiled and tested briefly
1993 without problems. More tests needed. The SIMs didn't compile
1996 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1998 * Fixed possible crash in silc_get_username in the
1999 lib/silcutil/silcutil.c.
2001 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Fixed a va_arg in silc/client_ops.c.
2005 * Oops, RC5 routines were named AES and caused some problems
2006 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2008 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Added new SilcIDIP structure into the lib/silccore/id.h and
2011 replaced the old `ip' fields from all SILC ID's to that type.
2012 This is a step towards IPv6 support.
2014 The silc_id_get_len takes now the ID as an extra argument.
2015 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2016 both IPv4 and IPv6 based ID's.
2018 The affected files are lib/silccore/id.[ch] and other files
2019 around the tree using these routines.
2021 * Removed the ID length arguments in server from various
2022 silc_server_send_notify_* routines -> they are not needed
2025 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Fixed memory leak in silc_encode_pem_file in the file
2028 lib/silcutil/silcutil.c.
2030 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Check minor version as well in the SKE. Affected files are
2033 silcd/protocol.c and lib/silcclient/protocol.c.
2035 * Added --identifier option to the server so that an identifier
2036 can be when creating the public key for the server. Affected
2037 file is silcd/silcd.c.
2039 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2040 lib/silccrypt/silcpkcs.c.
2042 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Register default ciphers and stuff when using -C option with
2045 the server. Affected file sildc/silcd.c.
2047 * Put back the servers public key filename format, it is better
2048 than the new one. For now, the client keys are saved with the
2049 new filename format. The affected file silc/client_ops.c.
2051 * Implemented the Cipher API for the rest of the ciphers that
2052 did not implement it or implemented it the wrong way.
2054 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Register default ciphers and stuff when using the -S option
2057 in the client. Affected file silc/silc.c. Same also when
2058 creating new key pair with -C option.
2060 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2062 * Fixed the silc_verify_public_key client operation function to
2063 save the public keys differently. The fingerprint is now
2064 used as filename and not the hostname. This way also the
2065 client keys are saved uniquely and not with hostnames. The
2066 affected file is silc/client_ops.c.
2068 * Trimmed the silc_hash_fingerprint function to remove extra
2069 whitespaces from the end of the fingerprint. The affected
2070 file is lib/silccrypt/silchash.c.
2074 * Added silc_cipher_register_default function to register all
2075 default ciphers. It can be used when configuration files
2076 does not exist and the application does not want any specific
2077 ciphers in any specific order.
2079 The SilcDList is now used as silc_cipher_list dynamically
2080 allocated cipher list. Removed the static list all together
2081 and now all ciphers must be allocated to the dynamic list.
2082 The silc_cipher_alloc routine was changed to check only the
2085 All silc_cipher_* routines that used to return int returns
2088 The affected files lib/silccrypt/silccrypt.[ch].
2090 * The same thing was done to silc_hash_* as for silc_cipher_*
2091 routines. Affected files lib/silccrypt/silchash.[ch].
2093 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2094 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2095 Added also silc_pkcs_[un]register[_default] functions.
2096 Removed the data_context from the PKCS API.
2098 * Added silc_hmac_register_default function to register default
2099 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2100 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2101 to unregister all hmacs at once.
2103 * Register the default ciphers, hash functions, PKCSs and HMACs
2104 if client's configuration file does not exist. The affected
2107 * The client did not load the hash functions from the SIM
2108 modules at all. Added support for this. Affected file is
2109 silc/clientconfig.c.
2111 * When decoding public key with silc_pkcs_public_key_decode, check
2112 the supported algorithm only if PKCS are registered. Affected
2113 file lib/silccrypt/silcpkcs.c. The same was done with the
2114 silc_pkcs_private_key_decode.
2116 * Fixed the SILC List routines to keep the list always in order.
2117 It used to change the list's order when traversing the list but
2118 not it preserves the order. Affected file lib/trq/silclist.h.
2120 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Added the client library to use the SilcSocketConnection's
2123 reference counter (by silc_socket_dup) to prevent the bug that
2124 the socket object may be freed underneath async operation.
2126 * The name resolv library checking fixes in the configure.in.pre.
2129 * Created new version of the protocol drafts for future
2130 development. The -03 drafts are the ones that will be changed
2131 in the trunk now and the -02 will remain as they are.
2133 * Send list of CUMODE notifys to the router when announcing
2134 the channel users to the router. Affected file silcd/server.c.
2135 If the router receiving channel founder CUMODE for a channel
2136 that already has channel founder it will send CUMODE notify
2137 to the sender to remove the channel founder rights from the
2138 announced client. Affected file silcd/packet_receive.c.
2140 * The CUMODE notify may now use Server ID as well as the entity
2141 who changes the mode. Updated protocool specs.
2143 * Updated INSTALL and README files.
2145 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * New web pages in the http://silc.pspt.fi. The pages was
2152 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Implemented the [DenyConnectin] config section in the server.
2155 Added silc_server_config_denied_conn to check whether incoming
2156 connection is denied. Affected file silcd/serverconfig.[ch].
2158 * Do not check the ports when checking the incoming configuration
2159 data if the port is 0, meaning any. Affected file is
2160 silcd/serverconfig.c.
2162 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Fixed buffer overflow in silc_string_compare in the file
2165 lib/silcutil/silcutil.c.
2167 * Fixed double free in silc_server_command_leave in the file
2170 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Fixed the version checking in the server. Affected file is
2175 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Fixed the configuration data fetching when accepting new
2178 connections in the server. Affected file silcd/server.c.
2180 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * Added `sender_entry' argument to the function
2183 silc_server_packet_relay_to_channel so that we can check
2184 whether some destination actually belongs to the same route
2185 the sender belongs (ie, we must not resend the packet to the
2186 sender). Affected file silcd/packet_send.[ch].
2188 * Added `servername' field to the SilcClientEntry in the server
2189 to hold the name of the server where client is from. Affected
2190 file is silcd/idlist.h.
2192 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Moved the channel message encrypting in the router betwen
2195 router connections from silc_server_channel_message to the
2196 silc_server_packet_relay_to_channel since we want to check
2197 whether we have anybody channel before encrypting anything.
2198 Affected files silcd/packet_[receive/send].c.
2200 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Fixed the [AdminConnection] server config section to support
2203 multiple entries. Affected file silcd/serverconfig.c.
2205 * Added support into the server to check the validity of the
2206 incoming connection before executing any KE or authentication
2209 * The connection configuration is now saved to the KE and
2210 connection auth protocol contexts and not fetched anymore in
2211 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2213 * The local hosts listenning address and port is also resolved
2214 now when starting the server. We want to have the socket object
2215 to include the real address and port for the listener. Added
2216 new function silc_net_check_local_by_sock into the files
2217 lib/silcutil/silcnet.[ch].
2219 * Fixed a broadcast bug in server -> do not broadcast if we
2222 * Fixed a routing bug. Do not route broadcast packets ever.
2223 Broadcast packets must be processed always and not routed since
2224 they may be destined to some other host than yourself and thus
2225 would get routed without no good reason. Affected file is
2228 * Added function silc_server_config_is_primary_route to check
2229 whether primary router connection has been configured (a router
2230 configuration that we are initiating). If there is not, we
2231 will assume that there is only two routers in the SILC network
2232 and we will use the incoming router connection as our primary
2233 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2235 * Changed the order of the broadcasting. Broadcast _after_ the
2236 packet has been processed not before. Affected file is
2239 * Fixed a [ClientConnection] parsing bug. The port was never
2240 parsed correctly thus resulting to port 0. Affected file
2241 silcd/serverconfig.c.
2243 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2244 argument and did not set the broadcast packet flag. Affected
2245 file silcd/packet_send.c. Fixed same bug in the function
2246 silc_server_send_notify as well.
2248 * If we receive NEW_ID packet for our own ID in the server, ignore
2251 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Removed the nickname from the Private Message Payload.
2256 Updated the code and the protocol specs.
2258 * Updated protocol specs for submitting to the IETF.
2260 * Tweaked the Random Number Generator a bit. Affected file
2261 lib/silccrypt/silcrng.c. Exported a new function
2262 silc_rng_[global]_add_noise which can be used to add more
2265 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Do not parse packets with different timeout when protocol
2268 is active -> may cause problem with rekey. Affected file
2271 * When server receives signoff notify it must not create
2272 new channel key if the client is on any channels since the
2273 sender of the signoff notify will create it.
2275 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Added printing of error messages during SKE protocol from the
2278 failure packet sent by server during SKE. Affected file
2281 * Removed the client's failure_callback handling with timeout
2282 and handle it immediately when received.
2284 * The SKE library returned wrong type in SUCCESS and FAILURE
2285 packets. They must be 32 bit MSB not 16 bit MSB.
2287 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Ok, rewrote the logic of the re-key and now it seems to work.
2290 I tested it on high traffic with frequent re-keys without
2291 problems. Added hmac_receive (and renamed hmac to hmac_send)
2292 in SilcClientConnection in lib/silcclient/client.h and
2293 in SilcIDListData in silcd/idlist.h. Also, removed the
2294 SilcPacketParserContext's cipher and hmac fields as they are
2295 not needed anymore and actually caused some problems when
2296 the ciphers and hmac's changed underneath the packet parser.
2298 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * If re-key protocol is active then process the incoming packets
2301 synchronously since we must assure that icoming packets encrypted
2302 with the old key is processed before the new keys is set to
2303 use. This is true other packets than for REKEY packets.
2304 Affected file silcd/server.c. The same was done to client library
2305 as well, affected file lib/silcclient/client.c.
2307 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Fixed bug in client and server to accept the force send if
2310 the packet is send from silc_[server/client]_packet_process
2311 function. Otherwise the packets are never delivered, oops.
2313 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Disable force sending of packets when REKEY protocol is active.
2316 We must assure that no packet is sent directly when rekey is
2317 performed. All packets must be sent through packet queue.
2318 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2319 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2320 function is silc_[server/client]_packet_send_real to check
2323 * Replaced the SIM paths from example config files to
2324 /usr/local/modules. Also, make install creates now
2325 /usr/local/silc/logs directory to hold all the SILC server
2328 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Made the configure.in.pre work on Solaris. Patch by salo.
2332 * Made all ciphers compatible with non-x86 machines. Defined
2333 CBC mode macros into lib/silccrypt/ciphers_def.h.
2335 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Fixed the make install.
2339 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * When MAC computation fails the silc_packet_decrypt returned 0
2342 even though it was supposed to return -1. Fixed this. The
2343 affected file is lib/silccore/silcpacket.c.
2345 * Do not replace the config files in /etc/silc (in make install)
2346 if they already exist. Affected file ./Makefile.am.
2348 * Do not send re-key packets immediately but through packet queue.
2349 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2351 * Changed silc_net_check_host_by_sock to return FALSE if the
2352 IP/DNS could not be resolved. Though, it returns the IP address
2353 now even if it could not resolve it (but returns also FALSE).
2354 Affected file lib/silcutil/silcnet.[ch].
2356 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Added silc_pkcs_decode_identifier to decode the public key's
2359 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2360 Added also silc_pkcs_free_identifier. Added also new context
2361 SilcPublicKeyIdentifier.
2363 * Added -S option to the silc client. It is used to dump the
2364 contents of the specified public key file.
2366 * Changed the PKCS api to return the public key length when
2367 setting the public key.
2369 * Fixed a fatal bug in the public and private key file loading.
2370 Affected file lib/silccrypt/silcpkcs.c.
2372 * Execute the packet parsing for client with zero (0) timeout
2373 if the protocol is active. Affected file silcd/server.c.
2375 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Made the key generation options to the silcd program. Added
2378 -C option, equivalent to client's option.
2380 * Added new [ServerKeys] config section to the server. It
2381 configures the server's public and private key.
2383 * Defined generic Public Key Payload into the protocol
2384 specification to send specific type of public keys and
2387 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2388 public key or certificate.
2390 * Implemented the GETKEY command to the server and to the
2391 client library and on user interface.
2393 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Made preliminary `make install' work.
2397 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Added SilcServerRekey context into silcd/idlist.h.
2401 * Added the PFS support as defined in the specification to the
2402 SKE protocol. Affected files lib/silcske/*.c.
2404 * Added `ske_group' field to the SilcServerRekey context to hold
2405 the number of the SKE group that is used with PFS in re-key.
2406 Affected file silcd/idlist.h.
2408 * Added PFS re-key support to the server. Affected file is
2411 * Added silc_protocol_cancel to cancel execution of the next
2412 state of the protocol. Affected file is
2413 lib/silccore/silcprotocol.[ch].
2415 * Added the re-key support with and without PFS to the client
2416 library. Re-key is performed once in an hour, by default.
2418 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2419 Added silc_client_rekey_callback and silc_client_rekey_final.
2420 Affected files are lib/silcclient/protocol.[ch] and
2421 lib/silcclient/client.[ch].
2423 * Removed the `hmac_key' and `hmac_key_len' fields from the
2424 SilcClientConnection structure; not needed. Affected file is
2425 lib/silcclient/client.h.
2429 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Do not ask whether user wants to use the negotiated private key
2432 for private messages, just use it. Affected file is
2433 silc/local_command.c.
2435 * Added `send_enc_key' and `enc_key_len' fields to the
2436 SilcIDListData structure since they are needed in the re-key
2437 phase. Affected file is silcd/idlist.[ch].
2439 * Implemented the simple re-key protocol into the server.
2440 Affected files silcd/server.c and silcd/protocol.[ch]. The
2441 re-key will be performed once in an hour, by default.
2443 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2444 Added silc_server_rekey, silc_server_rekey_callback and
2445 silc_server_rekey_final.
2447 * Removed Tunneled flag from the protocol. Updated the code
2448 and the specifications.
2450 * Adde `pfs' field to the SilcIDListData to indicate whether
2451 the PFS is to be performed in the re-key. Affected file is
2454 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2457 int64 of at least the xintXX size. If void * is less that 4
2458 bytes uint32 * will be used. Defined bool as boolean.
2460 * Changed _ALL_ unsigned long and unsigned int to uint32,
2461 unsgined short to uint16 in the source tree.
2463 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2464 not handle clients that has entry->data.registered == FALSE.
2465 They are not in the network anymore. Affected file is
2468 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Implemented the sending of the SERVER_SIGNOFF notify in the
2471 server. Affected file is silcd/server.c.
2473 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2474 Added also silc_notify_payload_encode_args into the
2475 lib/silccore/silcnotify.[ch].
2477 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2478 Affected file silcd/packet_receive.c.
2480 * Implemented the SERVER_SIGNOFF notify handling in the client
2481 library. Affected file lib/silcclient/client_notify.c. Also,
2482 implemnted the printing of the SERVER_SIGNOFF info to the
2483 application. Affected file silc/client_ops.c.
2485 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2486 if the deleting was successful. Affected file silcd/idlist.[ch].
2488 * Added support for public key authentication in the connection
2489 authentication protocol in the client library. Affected file
2490 lib/silcclient/protocol.c.
2492 * Changed the server's silc_idlist_get_clients_by_* interface
2493 to support already allocated array so that new entries may be
2494 added to pre-allocated array. Affected file silcd/idlist.[ch].
2495 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2496 and command replies.
2498 * All command reply functions in the server now calls the
2499 pending command callback even if error occured. This way the
2500 error will be delivered to the client as well. Affected files
2501 silcd/command.c and silcd/command_reply.c.
2503 * Fixed INFO command to return local server's info if no server
2504 was provided. Affected file lib/silcclient/command.c.
2506 * Removed RESTART command for good. Updated the code and the
2509 * Rewrote parts of the task system. It is a bit simpler now.
2510 Removed unsued task priorities. The affected files are
2511 lib/silcutil/silctask.[ch].
2513 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Moved the USERS printing from the library to the application.
2516 Affected files lib/silcclient/command.c and silc/client_ops.c.
2518 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Added channel key re-key support. The re-key is perfomed
2523 only by the router and is done once in an hour. Added `rekey'
2524 field to the SilcChannelEntry in the server. Affected files
2525 silcd/server.c and silcd/idlist.h.
2527 * Added silc_task_unregister_by_context into the file
2528 lib/silcutil/silctask.[ch].
2530 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Added SILC_UMODE_GONE mode to indicate when the client is not
2533 present in the SILC network. Added also support to the local
2534 command AWAY that will set this mode. Added support of showing
2535 "xxx is gone" in WHOIS command. The USERS command shows the
2536 gone status as well.
2538 * Fixed setting server and router operator privileges in the
2539 server's UMODE command. Affected file silcd/command.c.
2541 * Merged the SKE KE1 and KE2 payloads into one payload. The
2542 new KE payload is equivalent to the old KE2 payload.
2544 Cleaned up the SKE Start Payload parsing. It now uses the
2545 simple buffer unformatting to do the parsing. A lot faster
2548 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2549 to the SKE that is used to indicate whether both of the SKE
2550 parties should perform authentication. By default only the
2551 responder performs authentication. By setting this flag also
2552 the initiator must do authentication. By default it is unset
2553 since in normal SKE case, client to server connection, only
2554 the responder should do authentication. When doing SKE between
2555 two clients both should perform authentication. Updated the
2556 code and the protocol specs.
2558 * A little fix to IDENTIFY command in the server. Search the
2559 client first by hash not nickname. Affected file is
2562 * Fixed the silc_client_close_connection to support closing
2563 the client to client connections wihtout deleting too much
2564 data. Affected file lib/silcclient/client.c.
2566 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2567 are received if protocol used to be active but is not anymore
2568 the application would crash due to NULL pointer dereference.
2569 Affected files silcd/server.c and lib/silcclient/client.c.
2571 * Added `hash' field to the SilcClientConnection to include
2572 the hash function negotiated in the SKE protocol.
2574 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2575 to set the channel founder authentication data. A client can
2576 claim the founder rights later by providing the authentication
2577 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2578 This way the channel founder can regain the channel founder
2579 privileges even it is left the channel. This works only on
2580 local server and the client must be connected to the same
2581 server to be able to regain the founder rights. Updated the
2582 protocol specs accordingly.
2584 Added support to the CMODE command in the client to set the
2585 founder auth data. Read the README to see how to set it.
2587 Added support to the CUMODE command to claim the founder
2588 rights. Read the README to see how to do it.
2590 Added support for the founder authentication to the Channel
2591 Entry in the server. Affected file silcd/idlist.h.
2593 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2594 server's CMODE command. Affected file silcd/command.c.
2596 * Added the following new functions into lib/silccore/silcauth.[ch]:
2597 silc_auth_get_method and silc_auth_get_data.
2599 * The server now saves the remote hosts public key to the
2600 SilcIDListData pointer. Affected file silcd/protocol.c.
2602 * The normal server now does not remove the channel entry from
2603 the cache if the founder authentication data is set. It used
2604 to remove it if the founder was the last one on the channel on
2605 the server and left the channel. The auth data is saved and
2606 if the channel is re-joined later the old entry is used with
2607 the old auth data. Affected files silcd/command_reply.c and
2610 * Removed the `pkcs' field from the SilcIDListData structure
2611 in the server; it is not used. Affected file silcd/idlist.h.
2613 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Fixed packet processing on slow links. Partial packets were
2616 never re-processed because the incoming data buffer was cleared
2617 by the application. Application must not directly clear the
2618 sock->inbuf, the packet processing routines handle it. Fixed
2619 this in client library and in server.
2621 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Fixed the WHOIS and IDENTIFY send reply function to really
2624 check whether to send list or just one entry. Affected file
2627 * Cleaned up the LEAVE command's channel key distribution. The
2628 affected file silcd/command.c.
2630 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2631 can enforce the channel mode as well. In that case the ID
2632 includes the ID of the server. The code now enforces the
2633 mode change if the router have different mode than the server.
2635 * The notify client operation with CMODE_CHANGE notify can now
2636 return NULL client_entry pointer if the CMODE was not changed
2637 by client. Application must check for this.
2639 * Added <Server ID> argument to INFO command to support server
2640 info fetching by Server ID.
2642 * Added silc_server_announce_get_channel_users to get assembled
2643 packets of channel users of the specified channel. Affected
2644 file silcd/server.[ch].
2646 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2647 was freed underneath the ID Cache.
2649 * Re-announce clients when the server received CHANNEL_CHANGE
2650 notify from the router. Affected file silcd/packet_send.c.
2652 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2655 crashed since it did not handle the fact that there is no cipher
2656 called "3" and didn't check the error condition. Now fixed.
2658 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2659 flag. It can be used to send message requests.
2661 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Implemented the RESTART command in the client.
2665 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2666 notice type messages. Added notice printing to the user
2669 * The channel keys are not re-generated if the channel's mode
2670 is PRIVKEY, ie private key on the channel exists. Affected
2671 files silcd/server.c and silcd/command.c.
2673 * Fixed a little bug in channel message delivery when channel
2674 private keys are set in the server. Affected file is
2675 silcd/packet_send.c.
2677 * Changed the setting on channel->on_channel = TRUE from the
2678 silc_client_save_channel_key to the JOIN command reply. The
2679 key payload is not received if the private channel key is set.
2680 Affected file lib/silcclient/command_reply.c and the
2681 lib/silcclient/client_channel.c.
2683 * When the CMODE_CHANGE notify is sent and the channel private
2684 key mode is removed the channel key must be re-generated in
2685 other cells as well. Added this support for the router in the
2686 silcd/packet_receive.c.
2688 * Added new local command NOTICE to send notice message on
2689 channel. Affected file silc/local_command.[ch].
2691 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Added new local command ME to the client. It is used to send
2694 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2695 some action. Affected file silc/local_command.[ch].
2697 * Changed channel_message and private_message client operations
2698 to deliver the message flags to the application. Added also
2699 the `flags' arguments to the silc_client_send_channel_message
2700 and silc_client_send_private_message functions. Affected file
2703 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * Redefined the Private Message Payload to support private message
2706 keys and to support the new private message flags. Updated
2707 the protocol specs. Flags makes it possible to have for example
2708 CTCP style messages.
2710 * Added new type SilcPrivateMessagePayload and defined an API
2711 for it in the lib/silcclient/silcprivate.[ch].
2713 * Tested private message private keys successfully. Tested the
2714 private message key set, unset and list commands with the new
2717 * Redefined the Channel Message Payload to include the channel
2718 message flags (equal with private message flags) to support
2719 for example CTCP style messages.
2721 * Defined some of the message (for channel and private message)
2722 flags. Updated the protocol specs and added the flags to the
2723 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2725 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Added SilcKeyAgreementStatus type to the key agreement routines
2728 to indicate the current status and error if one occured.
2729 The status types are defined in the lib/silcclient/silcapi.h.
2731 * Added new local command KEY that is used to set and unset private
2732 keys for channels, set and unset private keys for private messages
2733 with remote clients and to send key agreement requests and
2734 negotiate the key agreement protocol with remote client. The
2735 key agreement is supported only to negotiate private message keys,
2736 it currently cannot be used to negotiate private keys for channels,
2737 as it is not convenient for that purpose.
2739 * Fixed a minor pending callback setting bug in the function
2740 silc_client_get_client_by_id_resolve, now the function works.
2741 Affected file lib/silcclient/idlist.c.
2743 * Added function silc_net_get_local_port to get local bound
2744 port by socket. Added to lib/silcutil/silcnet.[ch].
2746 * Added `sockets' and `sockets_count' fields to the SilcClient
2747 object. They hold the sockets of the listenning sockets in
2748 the client. Listenning sockets may be for example the key
2749 agreement server. Affected file lib/silcclient/client.[ch].
2750 Added functions the silc_client_add_socket and the
2751 silc_client_del_socket. They are exported to the application
2754 * Added ~./silc/clientkeys to support other client's public keys.
2756 * Renamed verify_server_key client operation to verify_public_key
2757 and added one argument to indicate the type of the connection
2758 (server, client etc.).
2760 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Added silc_server_connection_auth_request to handle the
2763 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2764 silcd/packet_receive.[ch].
2766 * Added silc_server_send_connection_auth_request into the
2767 silcd/packet_send.c to send the connection auth request packet.
2769 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2772 * Fixed the public key authentication in responder side in the
2773 server. The `auth_data' pointer includes the SilcPublicKey
2774 not the path to the public key. Affected file silcd/protocol.c.
2776 * Implemented the public key authentication in the initiator side
2777 in the server. Affected file silcd/protocol.c.
2779 * Removed the [RedirectClient] config section from the server
2780 configuration. Is not needed and I don't want to implement it.
2782 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Cleaned up the CMODE command in the server. It now works
2785 correctly and supports all the modes defined in the protocol.
2786 Affected file is silcd/command.c.
2788 * Added `hmac_name' field to the SilcChannelEntry in the server
2789 to hold the default HMAC of the channel. It can be set when
2790 creating the channel (with JOIN command). Affected files
2793 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2794 type to indicate the change of the current cipher and hmac
2795 on the channel. Client can safely ignore the <cipher> argument
2796 (if it chooses to do so) since the CHANNEL_KEY packet will
2797 force the channel key change anyway. The <hmac> argument is
2798 important since the client is responsible of setting the new
2799 HMAC and the hmac key into use.
2801 * Fixed the CMODE command in the client library as well.
2803 * Tested CMODE command in router environment successfully.
2805 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Show the version of the remote client (or server) when connecting
2808 to the server. It is logged to the log file. Affected file
2809 is silcd/protocol.c.
2811 * Fixed the KILLED notify handling in the client library. The
2812 client must be removed from all channels when receiving the
2815 Also, do not remove the client entry when giving the KILL
2816 command but when the KILLED notify is received.
2818 * Removed silc_idlist_find_client_by_nickname from the server.
2819 Not needed anymore. Affected files silcd/idlist.[ch].
2821 * Implemented the CHANNEL_CHANGE notify type handling to the
2822 server. Affected file silcd/server.c.
2826 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Added silc_server_send_notify_invite to send the INVITE
2829 notify between routers.
2831 * Implemented the INVITE command correctly to the server.
2833 * Implemented the INVITE notify type handling in the server.
2835 * Implemented the INVITE command to the client library and on the
2838 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added function silc_server_get_client_resolve to find the
2841 client entry by ID from all ID lists and then resolve it
2842 (using WHOIS) if it cannot be found. Affected file is
2845 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Implemented the BAN command to the client library.
2849 * The JOIN command in the server now checks the invite list
2852 * Changed the silc_command_reply_payload_encode_va and the
2853 silc_command_payload_encode_va to support that if argument is
2854 NULL it ignores and checks the next argument. Affected file
2855 lib/silccore/silccommand.c.
2857 * Added silc_server_send_notify_ban to send the BAN notify
2858 type between routers.
2860 * Chaned the silc_notify_payload_encode to support that if
2861 argument is NULL it ignores and checks the next argument.
2862 Affected file lib/silccore/silcnotify.c.
2864 * Tested ban lists in router environment successfully.
2866 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Implemented BAN command to the server, in silcd/command.[ch].
2870 * Removed the BAN and INVITE_LIST modes from the CMODE command
2873 * Added function silc_string_match to regex match two strings.
2874 Affected files lib/silcutil/silcutil.[ch].
2876 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Redefined parts of the SilcChannelEntry in the server to support
2879 the new ban and invite lists.
2881 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Redefined the INVITE command. The same command can be used to
2884 invite individuals to the channel but also to manage the invite
2885 list of the channel (to add to and remove from the invite list).
2886 Updated the protocol specs.
2888 * Added new command SILC_COMMAND_BAN that can be used to manage
2889 the ban list of the channel. Updated the protocol specs.
2891 * Removed the channel modes: the SILC_CMODE_BAN and the
2892 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2893 in the CMODE command. The equivalent features are now available
2894 using INVITE and BAN commands. Updated the protocol specs.
2896 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2897 in the network about change in the current ban list. The notify
2898 type is not used by the client.
2900 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2901 support the invite lists.
2903 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Added new function silc_string_regexify that converts string
2906 including wildcard characters into regex string that can
2907 be used by the GNU regex library. Added into the file
2908 lib/silcutil/silcutil.[ch].
2910 Added silc_string_regex_combine to combine to regex strings
2911 into one so that they can be used as one regex string by
2912 the GNU regex library. Added into the file
2913 lib/silcutil/silcutil.[ch].
2915 Added silc_string_regex_match to match two strings. It returns
2916 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2918 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Imported GNU regex to the soruce tree into lib/contrib.
2921 Fixed some compiler warning from the regex.c.
2923 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Fixed MOTD command in the server to work in router environment.
2927 * Fixed the MOTD command in the client library to support
2928 the server argument in the command.
2930 * Added `nickname_len' argument to the silc_idlist_add_client
2931 in the server, as the `nickname' argument may be binary data
2934 * Added silc_idlist_get_channels to return all channels from
2937 * Implemented LIST command to the server. Affected file is
2940 * Implemented the LIST command to the client library and on the
2943 * Added [<user count>] argument to the LIST command reply.
2944 With private channels the user count is not shown.
2946 * Updated TODO and README.
2948 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * The client entry's data.registered must be TRUE even with
2951 global client entry on global client list. The data.registered
2952 is used to check whether the client is anymore in the network,
2953 for example with WHOWAS command so it must be valid.
2955 * Fixed the WHOWAS command in the server. It now actually works
2956 in router environment. Added function into silcd/command_reply.c
2957 silc_server_command_reply_whowas_save.
2959 * Added silc_idlist_purge function to the silcd/idlist.c
2960 to periodically purge the ID Cache.
2962 * Fixed INFO command in the server. It works now in router
2963 environment. Added <server name> argument to the INFO command
2964 reply. Updated the protocol specs.
2966 * Fixed minor bug in silc_idcache_purge to not purge if the
2967 expire value is zero.
2969 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2970 they were buggy because of the WHOWAS information.
2972 * Fixed local command MSG to handle the async resolving of
2973 the remote client properly. It used to fail the first MSG.
2974 Affected file silc/local_command.c.
2976 * Added `data_len' field to SilcIDCache context.
2978 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Update TODO. Todo in commands in the server.
2982 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2985 used by routers as broadcast packet to inform other routers
2986 about the changed user mode.
2988 Implemented the notify handling in the server. Affected file is
2989 silcd/packet_receive.c. Added the function
2990 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2992 * Added new generic Channel Payload and deprecated the New Channel
2993 Payload. The New Channel Payload is now the generic Channel
2996 * Added new argument `mode' to the silc_server_send_new_channel
2997 as it is required in the Channel Payload now.
2999 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3000 and created a new and real SilChannelPayload to represent the
3001 new generic Channel Payload. Implemented the encode/decode
3002 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3004 * Added silc_server_get_client_channel_list to return the list
3005 of channels the client has joined for WHOIS command reply.
3006 Affected file silcd/server.[ch].
3008 * Implemented the channel list sending in the WHOIS command reply
3009 in server and in the client.
3011 Implemented the channel list displaying on the user interface
3012 as well. Affected file silc/client_ops.c.
3014 * Added silc_channel_payload_parse_list to parse list of Channel
3015 Payloads. It returns SilcDList list of SilcChannelPayloads.
3016 Client for example can use this function to parse the list of
3017 channels it receives in the WHOIS command reply. The caller
3018 must free the list by calling silc_channel_payload_list_free.
3019 Affected files lib/silccore/silcchannel.[ch].
3021 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Added one new argument <user mode> to the WHOIS command reply
3024 to return the mode of the user in SILC. Updated the protocol
3027 Implemented it to the server and client.
3029 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Fixed the mode printing on the user interface on joining.
3032 Affected file silc/client_ops.c.
3034 * Implemented the UMODE command and user modes in general to the
3035 client library and to the user interface.
3037 * Implemented the UMODE command to the server.
3039 * The server now sends UNKNOWN_COMMAND error status if client sends
3040 unknown command. Affected file silcd/command.c.
3042 * All server commands now handle the command identifier the right
3043 way when sending the command reply to the client. The client can
3044 use to identify the command replies with the identifier.
3046 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Added silc_server_get_client_route to resolve the route to
3049 the client indicated by the client ID. Affected file is
3052 * Added silc_server_relay_packet as general function to relay
3053 packet to arbitrary destination. This deprecates functions
3054 like _send_private_message_key, _relay_notify etc. Affected
3055 file is silcd/packet_send.[ch].
3057 Removed silc_server_send_key_agreement,
3058 silc_server_send_private_message_key and
3059 silc_server_packet_relay_notify functions from the file
3060 silcd/packet_send.[ch].
3064 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3065 server. Affected file silcd/packet_receive.[ch].
3067 * Implemented the KILL command to the client. Implemented the
3068 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3069 Affected files lib/silcclient/command[_reply].c and
3070 lib/silcclient/client_notify.c. Implemented the KILL notify
3071 printing in the user inteface.
3073 * Fixed a lot silc_parse_nick memory leaks from the client
3074 library in the file lib/silcclient/command.c.
3076 * Changed the silc_server_send_notify_on_channels's `sender'
3077 argument from SilcSocketConnection to SilcClientEntry to
3078 check the sender as entry and not as connection object and not
3079 to send to the client provided as argument. The affected file
3080 is silcd/packet_send.[ch].
3082 * The notify packets that are destined directly to the client used
3083 to not to be processed by the server. Now changed that and the
3084 server processes all notify packets. After relaying the packet
3085 to the client the notify packet is processed in the server.
3087 * The silc_server_free_client_data now checks whether there is
3088 pending outgoing traffic for the client and purges the data to
3089 the network before removing the client entry.
3091 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3094 an client is killed from the SILC Network. Updated the protocol
3097 Added new function silc_server_send_notify_killed to the
3098 silcd/packet_send.[ch].
3100 * Added function silc_server_packet_relay_notify to relay notify
3101 packets that are destined directly to a client. In this case
3102 the server does not process the notify packets but merely relays
3103 it to the client. Affected file silcd/packet_send.[ch].
3105 Added also silc_server_packet_process_relay_notify to check
3106 whereto relay the notify. Affected file is
3107 silcd/packet_receive.[ch].
3109 * Implemented the KILL command to the server.
3113 * Added the backup schema desgined last fall to the protocol
3114 specs for everyone to see. The specification is in the
3115 *-spec-xx.txt draft and the packet type definitions for the
3116 backup routers is in *-pp-xx.txt draft. Thusly, added also
3117 new packet type SILC_PACKET_CELL_ROUTERS.
3119 * A big security problem in the implementation discovered. The
3120 signoff of an client did not cause new channel key generation
3121 which it of course should've done. The channel keys must be
3122 always re-generated when client leaves (or signoffs) the channel.
3123 The silc_server_remove_from_channels funtion now handles
3124 the channel key re-generation.
3126 * Added `sender' argument to the silc_server_send_notify_on_channels
3127 to not to send the client provided as argument. Affected file
3128 silcd/packet_send.[ch].
3130 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Implemented OPER and SILCOPER commands into the server and
3135 * Added silc_auth_verify and silc_auth_verify_data to verify
3136 the authentication directly from the authentication payload.
3137 It supports verifying both passphrase and public key based
3138 authentication. Affected file lib/silccore/silcauth.[ch].
3140 * Added `hash' field to the SilcIDListData structure. It is the
3141 hash negotiated in the SKE protocol. Affected file is
3144 * Slight redesigning of the SilcAuthPayload handling routines.
3145 Do not send SilcPKCS but SilcPublicKey as argument.
3147 * Implemented the public key authentication support to the
3148 serverconfig. The public key is loaded from the provided path
3149 and saved as authentication data to void * pointer. Thus,
3150 changed the unsigned char *auth_data to void *auth_data;
3152 * Fixed SHUTDOWN command to send the reply before the server
3153 is shutdown. :) Affected file silcd/command.c.
3155 * Fixed fatal bug in CONNECT command. The hostname was invalid
3156 memory and server crashed. Affected file silcd/command.c.
3158 * Fixed fatal bug in CLOSE command. The server_entry became
3159 invalid but was referenced later in the command. Affected file
3162 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Fixed fatal bug in failure packet handling. Server ignored
3165 the failure and thus crashed when it came.
3169 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3172 that the command may be executed only once in (about) 2 seconds.
3173 The old SILC_CF_LAG flag is same but allows command bursts up
3174 to five before limiting.
3176 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3177 server code. Various commands now includes the CF_LAG_STRICT
3178 flag to disallow any kind of miss-use of the command.
3180 * Fixed the silc_buffer_unformat to not to allocate any data
3181 if the length of the data is zero. It used to allocate the
3182 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3184 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Changed the format of AdminConnection configuration section
3187 in the server. Added username of the admin to the format.
3188 Affected files silcd/serverconfig.[ch].
3190 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3191 to return admin configuration data by host, username and/or
3194 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Implemented WHOWAS command to the server. Added the functions:
3198 silc_server_command_whowas_parse,
3199 silc_server_command_whowas_send_reply,
3200 silc_server_command_whowas_from_client and
3201 silc_server_command_whowas_from_server
3203 * Added <Client ID> argument to the WHOWAS command reply. Updated
3204 the protocol specs accordingly.
3206 * Implemented WHOWAS command and command_reply to the client
3209 Implemented the WHOWAS printing on the user interface.
3211 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Added new argument to the WHOWAS command reply, the real name.
3214 It is an optional argument. Updated the protocol specs.
3216 * Added SilcIDCacheDestructor callback that is registered when
3217 the SilcIDCache is allocated. The callback is called when
3218 an cache entry in the ID Cache expires, or is purged from the
3219 cache. Added into lib/silccore/idcache.[ch].
3221 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3222 to destruct the client entries when the cache entry expires.
3223 Other ID Cache's in server and in the client library ignores
3226 * If the ID Cache entry's `expire' field is zero then the entry
3227 never expires. Added boolean `expire' argument to the
3228 silc_idcache_add function in the lib/silccore/idcache.[ch].
3229 If it is TRUE the default expiry value is used.
3231 * Added silc_server_free_client_data_timeout that is registered
3232 when client disconnects. By default for 5 minutes we preserve
3233 the client entry for history - for WHOWAS command.
3235 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Added support to the server to enforce that commands are not
3238 executed more than once in 2 seconds. If server receives
3239 commands from client more frequently, timeout is registered
3240 to process the commands. Affected file silcd/command.c.
3241 Added new function silc_server_command_process_timeout.
3243 * Changed NICK_NOTIFY handling in client library to check that
3244 if the client's nickname was changed, so there is no need to
3245 resolve anything from the server.
3247 * Removed error printing from the WHOIS and IDENTIFY commands.
3248 If error occurs then it is ignored silently in the client library.
3249 The application, however, may map the received error to
3250 human readable error string. The application currently maps
3251 the NO_SUCH_NICKNAME error to string.
3253 * Made the command status message public to the application. Moved
3254 them from lib/silcclient/command_reply.c to
3255 lib/silcclient/command_reply.h. The application can map the
3256 received command status to the string with the
3257 silc_client_command_status_message function.
3259 * Added check to the server to check that client's ID is same
3260 as the Source ID in the packet the client sent. They must
3263 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Added dist-bzip hook to the Makefile.am to make bzip2
3266 compressed distributions.
3268 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Server now enforces the maximum length for the nickname and
3271 the channel as protocol specification dictates. 128 bytes for
3272 nickname and 256 bytes for channel name.
3274 * Moved the WHOIS printing to the application. The client libary
3275 does not print out the WHOIS information anymore, the application
3276 must do it. Renamed silc_client_command_reply_whois_print to
3277 the silc_client_command_reply_whois_save.
3279 The client's idle time is also sent to the application now, and
3280 the idle is shown on screen.
3282 * Added silc_client_command_reply_identify_save to save the
3283 received IDENTIFY entries.
3285 * Do not check for channel private keys in message sending and
3286 reception if the channel does not have the PRIVKEY mode set.
3287 Affected file lib/silclient/client_channel.c.
3289 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3292 just surfaced after chaning the JOIN procedure.
3294 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Added silc_client_get_clients_by_list to get client entries
3297 from Client ID list, that is returned for example by JOIN
3298 and USERS command replies. The application should use this
3299 function for example when JOIN command reply is received to
3300 resolve the clients already on the channel (library does not
3301 do that anymore as USERS command reply is not used in the JOIN
3302 procedure anymore). Affected files lib/silcclient/silcapi.h and
3303 lib/silcclient/idlist.c.
3305 * JOIN command reply and USERS command reply returns now SilcBuffer
3306 pointers instead of unsigned char pointers when returning
3307 the client list and mode list.
3309 * Added <Client ID> argument to the JOIN command reply, mainly
3310 for the server to identify for which client the command was
3311 originally sent. Updated protocol specs accordingly.
3313 * Added SilcDlist private_key pointer to the SilcChannelEntry
3314 in the client to support the channel private keys. Affected
3315 file is lib/silcclient/idlist.h.
3317 * Added SilcChannelPrivateKey argument to the function
3318 silc_client_send_channel_message so that application can choose
3319 to use specific private ke if it wants to. If it is not provided,
3320 the normal channel key is used, unless private keys are set.
3321 In this case the first (key that was added first) is used
3322 as the encryption key.
3324 * Implemented the support for channel private key handling.
3325 Implemented the following functions:
3327 silc_client_add_channel_private_key,
3328 silc_client_del_channel_private_keys,
3329 silc_client_del_channel_private_key,
3330 silc_client_list_channel_private_keys and
3331 silc_client_free_channel_private_keys
3333 Affected file lib/silcclient/client_channel.c.
3335 * Added the support for the private keys in the channel message
3336 sending and encryption and in the message reception and
3337 decryption. Affected funtions are
3338 silc_client_send_channel_message and silc_client_channel_message.
3340 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added SKE's key verify callback to the client library's
3343 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3345 * Removed the statement that server (or router) must send USERS
3346 command reply when joining to the channel so that the client
3347 knows who are on the channel. Instead, the client list and
3348 client's mode list is now sent in the JOIN command reply to the
3349 client who joined channel. This is better solution.
3351 * Added function silc_server_get_users_on_channel and function
3352 silc_server_save_users_on_channel to the silcd/server.[ch].
3354 * Removed function silc_server_command_send_users from the
3357 * Do not show topic on the client library anymore. The topic is
3358 sent in the command reply notify to the application and the
3359 application must show the topic now.
3361 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Added client searching by nickname hash into the IDENTIFY and
3364 WHOIS commands in the server as they were clearly missing from
3365 them. Affected file is silcd/command.c.
3367 * Fixed a bug in private message receiving in the client library.
3368 The remote ID was freed and it wasn't supposed, now it is
3371 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Minor fix to the channel payload; allocate the data area, as it
3374 needs to be of specific length.
3376 * If the key agreement port is zero then the operating
3377 system will define the bound port. Affected files are
3378 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3380 * Added new function silc_channel_payload_decrypt into the file
3381 lib/silccore/silcchannel.[ch].
3383 * Moved the channel message etc, check from silc_packet_decrypt
3384 to applications. The library calls now a generic
3385 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3386 when the packet is either normal or special. This was done to
3387 allow more wide range of checking that was not allowed when
3388 the code was in library. Now applications can do virtually any
3389 checks to the packet and return to the library the decision how
3390 the packet should be processed. Affected files are
3391 lib/silccore/silcpacket.[ch].
3393 Added silc_server_packet_decrypt_check to the server and
3394 silc_client_packet_decrypt_check to the client library.
3396 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3397 to send with specified source and destination information.
3399 * Channel message delivery between routers was broken after the
3400 channel key distribution was fixed earlier. The channel key
3401 was used be to distributed to other routers as well which is not
3402 allowed by the protocol. Now this is fixed and channel keys
3403 really are cell specific and the channel message delivery between
3404 routers comply with the protocol specification.
3406 * Fixed various commands in server to check also the global list
3407 for the channel entry and not just the local list. The affected
3408 file silcd/command.c.
3410 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Added assert()s to buffer formatting and unformatting routines
3413 to assert (if --enable-debug) when error occurs. Affected
3414 file: lib/silcutil/silcbuffmt.c.
3416 * Changed to auto-reconnect to check whether the remote host is
3417 router and register the re-connect timeout if it is. It used
3418 to check that whether we are normal server, but router must do
3419 auto-reconnect with another router as well. Affected file
3422 * Removed the [<key len>] option from CMODE command as the cipher
3423 name decides the key length, nowadays. See the defined ciphers
3424 from the protocol specification.
3426 * Added [<hmac>] option to the CMODE command to define the HMAC
3427 for the channel. Added SILC_CMODE_HMAC channel mode.
3429 * Added [<hmac>] option for the JOIN command so that user can
3430 select which HMAC is used to compute the MACs of the channel
3433 * Added Hmac field to the Channel Message Payload. The integrity
3434 of plaintext channel messages are now protected by computing
3435 MAC of the message and attaching the MAC to the payload. The
3436 MAC is encrypted. Now, it is clear that this causes some
3437 overhead to the size of the packet but rationale for this is that
3438 now the receiver can verify whether the channel message decrypted
3439 correctly and also when private keys are set for the channel the
3440 receiver can decrypt the packet with several keys and check from
3441 the MAC which key decrypted the message correctly.
3443 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3444 lib/silccrypt/silccipher.[ch].
3446 * Added silc_hash_len to return the digest length into the
3447 lib/silcrypt/silchash.[ch].
3449 * Rewrote parts of Silc Channel Payload interface in the
3450 lib/silccore/silcchannel.[ch]. The encode function now also
3451 encrypts the packet and parse function decrypts it.
3453 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3455 * Fixed a minor formatting bug in the SKE's key material processing.
3456 It actually might have processed the keys wrong way resulting
3459 * Redefined the mandatory HMAC algorithms and added new algorithms.
3460 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3461 and hmac-md5 truncated to 96 bits. The mandatory is now
3462 hmac-sha1-96. Rest are optional (including the one that used
3463 to be mandatory). Rationale for this is that the truncated HMAC
3464 length is sufficient from security point of view and can actually
3465 make the attack against the HMAC harder. Also, the truncated
3466 HMAC causes less overhead to the packets. See the RFC2104 for
3469 * Added new [hmac] configuration section. The SKE used to use
3470 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3471 is of course wrong. The official names that must be proposed in
3472 the SKE are the ones defined in the protocol specification
3473 (hmac-sha1-96 for example). The user can configure any hmac
3474 using any hash function configured in the [hash] section. At
3475 least, the mandatory must be configured.
3477 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3479 * Added HMAC list to the SKE proposal list. It has now both
3480 hash algorithm list and HMAC list. This makes the protocol
3481 incompatible with previous versions. The SKE now seems to work
3482 the way it is supposed to work, for the first time actually.
3484 * Defined plain Hash algorithms to the protocol specification.
3487 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Implemented support for key agreement packets into the server.
3490 Added functions silc_server_key_agreement and
3491 silc_server_send_key_agreement. Other than these functions,
3492 server has nothing to do with this packet.
3494 * Added support for private message key packets into the server.
3495 Added functions silc_server_private_message_key and
3496 silc_server_send_private_message_key.
3500 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3501 called in the protocol's final callback instead in the END
3502 protocol state. This makes a little more sense and in the same
3503 time in client we can use the same protocol routines for normal
3504 key exchange and to key agreement packet handling as well.
3506 * Added to both client's and server's KE protocol context the
3507 SilcSKEKeyMaterial pointer to save the key material. We will
3508 bring the key material to the protocol's final callback by doing
3509 this. The final callback must free the key material.
3511 * Added SKE's packet_send callback into client's KE protocol
3512 context so that the caller can choose what packet sending function
3513 is used. This way we can use different packet sending when
3514 doing normal SKE when doing key agreement packet handling (in
3515 the key agreement packet handling we do not want to encrypt
3518 * Implemented the responder side of the key agreement routines
3519 in the client. The client can now bind to specified port and
3520 accept incoming key negotiation. The key material is passed
3521 to the application after the protocol is over.
3523 * Implemented the processing of incoming Key Agreement packet
3524 in the client. Added function silc_client_key_agreement to
3527 * Implemented the intiator side of the key agreement routines
3528 in the client. The client can now initiate key agreement with
3529 another remote client. The key material is passed to the
3530 application after the protocol is over.
3532 * Created client_keyagr.c to include all the key agreement
3535 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3536 SILC_TASK_CALLBACK except that it is not static.
3538 * Created client_notify.c and moved the Notify packet handling
3539 from the client.[ch] into that file.
3541 * Created client_prvmsg.c and moved all private message and
3542 private message key routines from the client.[ch] into that file.
3544 * Create client_channel.c and moved all channel message and
3545 channel private key routines from the client.[ch] into that file.
3547 * Changed silc_client_get_client_by_id_resolve to resolve with
3548 WHOIS command instead of IDENTIFY command, in the file
3549 lib/silclient/idlist.c.
3551 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Implemented the SKE's responder side to the Client library.
3555 * When FAILURE is received to the protocol do not trust it
3556 blindly. Register a timeout to wait whether the remote closes
3557 the connection as it should do it, only after that process the
3558 actual failure. This was changed to both client and server.
3560 * Added client_internal.h to include some of the structures
3561 there instead of client.h in lib/silcclient/.
3563 * Added function silc_task_unregister_by_callback to unregister
3564 timeouts by the callback function.
3566 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Some "Incomplete WHOIS info" errors has been appearing on the
3569 log files. Took away the entry->userinfo check from WHOIS
3570 reply sending. The entry->userinfo is now " " if client did not
3571 provide one. I thought this was fixed earlier but something
3572 is wrong still. Let's see if the error still appears.
3574 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Fixed a minor bug in the login when the channel key is
3577 re-generated in the server. It used to generate the key in
3578 wrong order and thus caused problems in the channel traffic.
3580 * Fixed a minor bug in channel key distsribution after
3581 KICK command. The key was not sent to the router even though
3584 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Added silc_ske_process_key_material_data as generic routine
3587 to process any key material as the SILC protocol dictates. The
3588 function is used by the actual SKE library but can be used by
3589 applications as well. This relates to the private message keys
3590 and the channel private keys since they must be processed the
3591 same way the normal SILC session keys. The protocol dictates
3592 this. Affected files: lib/silcske/silcske.[ch].
3594 Added also silc_ske_free_key_material to free the
3595 SilcSKEKeyMaterial structure.
3597 * Defined silc_cipher_set_key function to set the key for
3598 cipher without using the object's method function. The affected
3599 files: lib/silccrypt/silccipher.[ch].
3601 * Implemented silc silc_client_add_private_message_key,
3602 silc_client_add_private_message_key_ske,
3603 silc_client_del_private_message_key,
3604 silc_client_list_private_message_keys and
3605 silc_client_free_private_message_keys functions in the
3608 Added functions silc_client_send_private_message_key to send
3609 the Private Message Key payload and silc_client_private_message_key
3610 to handle incoming Private Message Key payload.
3612 * Added Cipher field to the Private Message Key payload to set
3613 the cipher to be used. If ignored, the default cipher defined
3614 in the SILC protocol (aes-256-cbc) is used.
3616 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Removed lib/silcclient/ops.h file.
3620 Redefined parts of the SILC Client Library API. Created new
3621 file silcapi.h that deprecates the ops.h file and defines the
3622 published Client Library API. Defined also private message key
3623 API and channel private key API into the file.
3625 This is the file that the application must include from the
3626 SILC Client Library. Other files need not be included by
3627 the application anymore.
3629 * Added new key_agreement client operation callback and also
3630 defined the Key Agreement library API for the application.
3632 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3635 is used by clients to request key negotiation between another
3636 client in the SILC network. If the negotiation is started it
3637 is performed using the SKE protocol. The result of the
3638 negotiation, the secret key material, can be used for example
3639 as private message key.
3641 Implemented the Key Agreement payload into the files
3642 lib/silccore/silauth.[ch].
3644 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Redefined ciphers for the SILC protocol. Added some new ciphers
3647 and defined the key lengths for the algorithms. Changed the
3648 code accordingly. The default key length is now 256 bits.
3650 * Fixed SKE key distribution function silc_ske_process_key_material
3651 when the key length is more than 128 bits. The default key
3652 length in SILC is now 256 bits.
3654 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3655 to indicate unsupported algorithm.
3657 * Renamed rijndael.c to aes.c and all functions as well.
3659 * Fixed a long standing channel key setting bug in client library.
3660 Weird that it has never surfaced before.
3662 * Fixed bug in channel deletion. If the entire channel is removed
3663 then it must also delete the references of the channel entry
3664 from the client's channel list as the client's channel entry and
3665 the channel's client entry share same memory.
3667 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Implemented CONNECT and SHUTDOWN commands in the client.
3671 * Implemented CLOSE command to the client.
3673 * Added the function silc_idlist_find_server_by_name into the
3674 files silcd/idlist.[ch].
3676 Added the function silc_idlist_find_server_by_conn into the
3677 files silcd/idlist.[ch].
3679 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * DIE command was renamed to SHUTDOWN. Updated the both code
3684 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3685 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3687 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3690 * Added function silc_server_create_connection function to create
3691 connection to remote router. My server implementation actually
3692 does not allow router to connect to normal server (it expects
3693 that normal server always initiates the connection to the router)
3694 so the CONNECT command is only good for connecting to another
3697 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3700 or some other client was kicked from the channel.
3702 Implemented the handling of the notify type to both client
3705 Implemented silc_server_send_notify_kicked to send the KICKED
3706 notify. It is used to send it to the server's primary router.
3708 * Implemented the KICK command into server and client.
3710 * Added `query' argument to the silc_idlist_get_client function
3711 to indicate whether to query the client from server or not if
3714 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3715 to indicate that the client is not channel founder.
3719 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Removed the rng context from SilcPacketContext structure and
3722 changed that the packet routine uses the Global RNG API.
3724 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added support for quit message that client can "leave" on the
3727 channel when it quits the SILC. It is ditributed inside the
3728 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3730 Added silc_server_free_client_data that will take the
3731 signoff message as argument.
3733 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3735 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Updated parts of the protocol specification to keep it up
3740 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3743 payloads in one packet.
3745 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3746 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3747 use now the new List flag.
3749 * Also deprecated the following packet types: REPLACE_ID,
3750 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3752 * Added list support for Notify packet in server.
3754 * Added silc_server_send_notify_channel_change to send the
3755 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3756 the silc_server_send_replace_id.
3758 * Added silc_server_send_notify_nick_change to send the
3759 NICK_CHANGE notify type. Deprecates the function
3760 silc_server_send_replace_id.
3762 * Added silc_server_send_notify_join to send the JOIN notify type.
3763 Deprecates the function silc_server_send_new_channel_user.
3765 * Added silc_server_send_notify_leave to send LEAVE notify type.
3766 Deprecates the function silc_server_send_remove_channel_user.
3768 * Added silc_server_send_notify_cmode and
3769 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3770 types. Deprecates the silc_server_send_set_mode function.
3772 * Added SERVER_SIGNOFF notify type to indicate that server has
3773 quit. This means that all clients on the channel from that
3774 server will drop. This can be also used when netsplit happens.
3776 Deprecated REMOVE_ID packet type since it is not needed anymore
3779 Added silc_server_send_notify_server_signoff to send the
3780 SERVER_SIGNOFF notify type. Deprecates the function
3781 silc_server_send_remove_id.
3783 Added also silc_server_send_notify_signoff to send the
3784 SIGNOFF notify type.
3786 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3787 SILC protocol from this day on. Changed the protocol
3788 specification as well.
3790 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3791 notify type. It is used between routers to notify about
3792 topic changes on a channel.
3794 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3797 * Partly updated the protocol specification to comply with the
3798 changes now made. It is still though a bit outdated.
3800 * The JOIN notify type now takes one extra argument <Channel ID>.
3801 The packet used to be destined to the channel but now the
3802 JOIN type may be sent as list thus it is impossible to
3803 destine it to any specific channel. By adding this argument
3804 it is again possible.
3806 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Added CREDITS file. The CHANGES and CREDITS file will appear
3809 in the distribution as well.
3811 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3814 types in the server's silcd/packet_receive.c.
3816 * Implemented CMODE and CUMODE to work in router environment.
3818 * Fixed minor encoding and decoding buglet from the
3819 lib/silccore/silcmode.c.
3821 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3824 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3826 * Changed all SilcConfigServer* and silc_config_server* to
3827 SilcServerConfig* and silc_server_config*, respectively.
3830 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Associated the ID (client or server ID) to the Authentication
3833 Payload to avoid any possibility of forging. Updated the
3834 protocol specification and the code accordingly.
3836 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * The RSA key length is now save to the RsaKey context in the
3839 key generation process in lib/silccrypt/rsa.c. The key length
3840 is now used to figure out the maximum size of the block allowed
3841 to be encrypted/signed.
3843 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3844 is equivalent to the silc_mp_mp2bin but does not allocate any
3847 * Changed silc_mp_mp2bin API to take length argument. If it is
3848 non-zero then the buffer is allocated that large. If zero, then
3849 the size is approximated using silc_mp_sizeinbase, which however
3852 * Created Global RNG API which is global RNG that application can
3853 initialize. After initializing, any routine anywhere in the
3854 code (including library) can use RNG without allocating a new
3855 RNG object. This was done to allow this sort of use of the
3856 RNG in code that has no chance to allocate RNG object. All
3857 applications currently allocate this and many routines in the
3858 library use this. Affected file lib/silccrypt/silcrng.[ch].
3860 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3861 it to use the Global RNG API.
3863 * Defined Authentication Payload into protocol specification that
3864 is used during SILC session to authenticate entities. It is
3865 used for example by client to authenticate itself to the server
3866 to obtain server operator privileges.
3868 Implemented this payload into the lib/silccore/silcauth.[ch].
3869 Implemented also routines for public key based authentication
3870 as the new protocol specification dictates.
3872 Moved definitions of different authentication methods from
3873 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3875 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3876 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3877 silc_pkcs_verify_with_hash functions into the file
3878 lib/silccrypt/silcpkcs.[ch].
3880 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * The client entry's userinfo pointer must be always valid.
3883 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3884 will fail since it requires the userinfo. Now, the userinfo
3885 is allocated as "" if actual userinfo does not exist. Actually,
3886 it must exist and it is totally Ok to drop client connections
3887 that does not announce the userinfo. However, we will make
3888 this workaround for now.
3890 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3891 to return the remote port by socket.
3893 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3896 SILC_SERVER_PENDING_EXEC and added an new macro
3897 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3898 data or when error occurs while processing the pending command.
3900 Added new argument `destructor' into silc_server_command_pending
3901 and to the SilcServerCommandPending object. This destructor is
3902 now called after calling the pending callback or if error occurs
3903 immediately. If error occurs the actual pending callback won't
3904 be called at all - only the destructor. The destructor may be
3905 NULL if destructor is not needed.
3907 All this applies for client library code as well. Similar
3908 changes were made there as well for the pending commands.
3910 In the client, the application must now allocate the
3911 SilcClientCommandContext with the silc_client_command_alloc
3914 * Added reference counter to the SilcServerCommandContext. Added
3915 function silc_server_command_alloc and silc_server_command_dup
3918 Same type of functions added to the client library for the same
3921 * Removed the cmd_ident from IDListData away since it is now
3922 global for all connections. It is the command identifier used
3923 in command sending and with pending commands. The affected file
3926 * Added reference counter to the SilcSocketConnection objecet to
3927 indicate the usage count of the object. The object won't be
3928 freed untill the reference counter hits zero. Currently only
3929 server uses this, and client ignores it. The client must be
3930 set to use this too later. The affected files are
3931 lib/silccore/silcsockconn.[ch]. Added also the function
3932 silc_socket_dup to increase the reference counter.
3934 This was mainly added because it is possible that the socket
3935 is removed underneath of pending command or other async
3936 operation. Now it won't be free'd and proper DISCONNECTING
3937 flags, etc. can be set to avoid sending data to connection that
3938 is not valid anymore.
3940 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3941 the connection. After that it sets SILC_SET_DISCONNECTED.
3942 It is, however, possible that the socket data is not still freed.
3943 The silc_server_packet_process now checks that data is not
3944 read or written to connection that is DISCONNECTED. The socket
3945 get's freed when the reference counter hits zero.
3947 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Changed the client operation API: channel_message operation's
3950 `sender' is now the client entry of the sender, not the nickname
3951 and the `channel' is the channel entry, not the channel name.
3953 In the private_message operation the `sender' is now also the
3954 client entry of the sender not the nickname.
3956 Affected file is lib/silcclient/ops.h and all applications
3957 using the client operations.
3959 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Moved the calling of ops->connect() from connect_to_server_final
3962 into receive_new_id functin since that is the point when the
3963 client is actually allowed to send traffic to network. The
3964 affected file is lib/silcclient/client.c.
3966 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3969 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3970 (if needs broadcasting) instead of broadcasting the packets one
3971 by one which would make a burst in the network traffic.
3973 * Added `broadcast' argument to the functions in silcd/server.[ch]
3974 silc_server_create_new_channel[_with_id] to indicate whether
3975 to send New Channel packet to primary router.
3977 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added new function into the silcd/server.[ch] files:
3980 silc_server_create_new_channel_with_id to create new channel with
3981 already existing Channel ID.
3983 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3984 lib/silccore/silcpacket.h. This packet is used t send list of
3985 Set Mode payloads inside one packet. Server uses this to set
3986 the modes for the channels and clients on those channels, that it
3987 announced to the router when it connected to it. The protocol
3988 specification has been updated accordingly.
3990 * The silc_server_new_channel did not handle the packet coming
3991 from normal server as it normally does not send that. However,
3992 when it announces its channels it does send it. Implemented
3993 the support for that.
3995 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3996 into the file lib/silccore/id.h.
3998 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Fixed memory leaks in the functions silc_idlist_del_client,
4001 silc_idlist_del_channel and silc_idlist_del_server in the file
4002 silcd/idlist.c. All of those leaked like a sieve.
4004 * Fixed some small memory leaks in the client's function
4005 silc_client_notify_by_server.
4007 * Added functions into silcd/server.c: silc_server_announce_clients,
4008 silc_server_announce_channels and silc_server_announce_server.
4009 These functions are used by normal and router server to announce
4010 to its primary router about clients, channels and servers (when
4011 router) that we own. This is done after we've connected to the
4014 These functions effectively implements the following packet types:
4015 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4016 and SILC_PACKET_NEW_ID_LIST.
4018 * Added new functions into the silcd/packet_receive.[ch]:
4019 silc_server_new_id_list, silc_server_new_channel_list and
4020 silc_server_new_channel_user_list to handle the incoming
4021 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4023 * Added support of changing Channel ID in the function
4024 silc_server_replace_id. If the server that announces a channel
4025 to the router already exists in the router (with same name but
4026 with different Channel ID), router is responsible to send
4027 Replace ID packet to the server and force the server to change
4028 the Channel ID to the one router has.
4030 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4031 client that the Channel ID has been changed by the router. The
4032 normal server sends this to the client. Client must start using
4033 the new Channel ID as the channel's ID.
4035 Implemented handling of this new type into lib/silcclient/client.c
4036 into the function silc_client_notify_by_server.
4038 * Added new function silc_idlist_replace_channel_id into the files
4039 silcd/idlist.[ch] to replace the Channel ID.
4041 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Call silc_server_command_identify_check always when processing
4044 the IDENTIFY command in silcd/command.c
4046 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4049 send keepalive packets. The packet can be sent by clients,
4050 servers and routers.
4052 Added function silc_socket_set_heartbeat into the file
4053 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4054 If not set, the heartbeat is not performed. The actual
4055 heartbeat is implemented in the low level socket connection
4056 library. However, application is responsible of actually
4059 Added silc_server_send_heartbeat to send the actual heartbeat
4060 packet into silcd/packet_send.[ch]. Server now performs
4061 keepalive with all connections.
4063 * Added silc_task_get_first function into lib/silcutil/silctask.c
4064 to return the timeout task with shortest timeout. There was a bug
4065 in task unregistration that caused problems. TODO has been
4066 updated to include that task system must be rewritten.
4068 * The client library will now resolve the client information when
4069 receiving JOIN notify from server for client that we know but
4070 have incomplete information.
4072 * Rewrote parts of silc_server_remove_from_channels and
4073 silc_server_remove_from_one_channel as they did not remove the
4074 channel in some circumstances even though they should've.
4076 * Encryption problem encountered in server:
4078 The LEAVE command used to send the Channel Key packet to the
4079 router immediately after generating it. However, the code
4080 had earlier sent Remove Channel user packet but not immediately,
4081 ie. it was put to queue. The order of packets in the router
4082 was that Channel Key packet was first and Remove Channel User
4083 packet was second, even though they were encrypted in the
4084 reverse order. For this reason, MAC check failed. Now, this
4085 is fixed by not sending the Channel Key packet immediately but
4086 putting it to queue. However, this is more fundamental problem:
4087 packets that are in queue should actually not be encrypted
4088 because packets that are sent immediately gets encrypted
4089 actually with wrong IV (and thus MAC check fails). So, packets
4090 that are in queue should be encrypted when they are sent to
4091 the wire and not when they put to the queue.
4093 However, the problem is that the current system has not been
4094 designed to work that way. Instead, the packet is encrypted
4095 as soon as possible and left to the queue. The queue is then
4096 just purged into wire. There won't be any fixes for this
4097 any time soon. So, the current semantic for packet sending
4100 o If you send packet to remote host and do not force the send
4101 (the packet will be in queue) then all subsequent packets to the
4102 same remote host must also be put to the queue. Only after the
4103 queue has been purged is it safe again to force the packet
4106 o If you send all packets immediately then it safe to send
4107 any of subsequent packets through the queue, however, after
4108 the first packet is put to queue then any subsequent packets
4109 must also be put to the queue.
4111 Follow these rules and everything works fine.
4113 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Added new function silc_server_remove_clients_by_server to
4116 remove all client entries from ID list when the server connection
4117 is lost. In this case it is also important to invalidate all
4118 client entires as they hold the invalid server entry. This
4119 fixes fatal bug when server has lost connection and will reconnect
4122 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Made some sanity checks to silc_server_daemonise like to check
4125 whether the requested user and group actually exists.
4127 * Added sanity check to SKE's silc_ske_responder_finish to check
4128 that the public and private key actually is valid.
4130 * Invalidate the client's nickname when receiving Replace ID
4131 packet and the Client ID is being replaced. This means that the
4132 server will query the nickname if someone needs it (client)
4135 * Sort the ID Cache in client library when the ID Cache data
4136 has changed (needs sorting).
4138 * Do not allow for SILC client to create several connections to
4139 several servers. The client does not support windows right now
4140 and generating multiple connections causes weird behaviour.
4142 Irssi-silc client does support windows and can handle several
4143 connections without problems, see: www.irssi.org and SILC plugin.
4145 * Fixed some places where client was added to the IDList. The
4146 rule of thumb is following (in order to get everything right):
4147 If the client is directly connected local client then the
4148 `connection' argument must be set and `router' argument must be
4149 NULL to silc_idlist_add_client function. If the client is not
4150 directly connected client then the `router' argument must
4151 bet set and the `connection' argument must be NULL to the
4152 silc_idlist_add_client function.
4154 * The funtion silc_server_packet_send_local_channel actually did
4155 not check whether the client was locally connected or not. It
4156 does that now. Fixed a bug related to LEAVE command.
4158 * Fixed Remove Channel User payload parsing bug in server's
4159 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4161 * The server's silc_server_save_channel_key now checks also the
4162 global ID list for the channel as it might not be in the local
4163 list. Fixed a bug related to LEAVE command.
4165 * Is this the end of the [<unknown>] buglet that has been lurking
4166 around for a long time? A little for loop fix in server's
4167 silc_server_command_whois_parse that is used by both IDENTIFY
4168 and WHOIS command. At least, this was a clear bug and a cause
4169 of one type of [<unknown>] buglet.
4171 * WHOIS and IDENTIFY commands call the function
4172 silc_server_command_[whois/identify]_check function even if
4173 we are not router server.
4175 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added --with-gmp configuration option. If set the GMP
4178 is always compiled in the SILC source tree. If not set then
4179 it is checked whether the system has the GMP3 installed. If
4180 it has then the GMP won't be compiled (the system's headers
4181 and library is used), if it doesn't have it then the GMP is
4182 compiled in the SILC source tree.
4184 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Changed RSA private exponent generation to what PKCS #1
4187 suggests. We try to find the smallest possible d by doing
4188 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4189 not security fix but optimization.
4191 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Added new config entry [Identity] to fork the server and run
4194 it as specific user and group. A patch from Bostik.
4196 * Imported Dotconf configuration library into lib/dotconf.
4197 This will be used to create the SILC configuration files later.
4198 It will appear in the distsribution after this commit.
4200 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * A big code auditing weekend happening. Auditing code for
4203 obvious mistakes, bugs and errors. Also, removing any code
4206 Removed files for being obsolete:
4208 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4209 inline in the file lib/silcutil/silcbuffer.h)
4211 o lib/silcutil/silcbufutil.c (the header has inline versions)
4213 Changed code to fix possible error conditions:
4215 o The buffer formatting routines now check that the destination
4216 buffer really has enough space to add the data. This applies for
4217 both buffer formatting and unformatting
4218 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4219 unformatting was changed to accomodate following rules:
4220 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4221 sent to the function while XXX_*STRING will not allocate or copy
4222 the data into the buffer. Instead it sets the pointer from the
4223 buffer into the pointer sent as argument (XXX_*STRING used to
4224 require that the pointer must be allocated already). This change
4225 makes this whole thing a bit more consistent and more optimized
4226 (note that the data returned in the unformatting with XXX_*STRING
4227 must not be freed now). The routines return now -1 on error.
4229 o Tried to find all code that use buffer_format and buffer_unformat
4230 and added return value checking to prevent formatting and
4231 especially unformatting errors and possible subsequent fatal
4234 o Changed ske->x and ske->KEY to mallocated pointers in
4235 lib/silcske/silcske.h. Fixed possible data and memory leak.
4237 o Added return value checking to all *_parse* functions. Fixed
4238 many memory leaks as well.
4240 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4241 so that buffer overflows would not happen. All code now also
4242 checks the return value as it can fail.
4244 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Added reconnection support to server if the normal server looses
4247 its connection to the router (for example if router is rebooted).
4248 The server performs normal reconnection strategy implemented
4249 to the server. Affected file silcd/server.c.
4251 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Added new packet type SILC_PACKET_SET_MODE that is used to
4254 distribute the information about changed modes (for clients,
4255 channels and clients channel modes) to all routers in the
4256 network. Updated the protocol specification accordingly.
4258 Added functions into silcd/packet_send.c and
4259 silcd/packet_receive.c: silc_server_send_set_mode,
4260 silc_server_set_mode.
4262 Added new files silcmode.[ch] into lib/silccore that implements
4263 the encoding and decoding of Set Mode Payload. Added new type
4264 SilcSetModePayload. Moved the definitions of different modes
4265 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4267 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Oops, a little mistake in server's connection authentication
4270 protocol. The protocol is not ended with FAILURE but with
4271 SUCCESS if the authentication is Ok. :) Affected file is
4274 * Implemented NICK_CHANGE notify handling in server in the file
4275 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4276 the local clients on the channel. After the changing nickname
4277 in router environment snhould work and the [<unknown>] nickname
4278 should appear no more.
4280 The silc_server_replace_id function that receives the Replace ID
4281 payload now sends the NICK_CHANGE notify type also in the file
4282 silcd/packet_receive.c
4284 * Changed WHOIS and IDENTIFY command to support the maximum amount
4285 of arguments defined in protocol specs (3328 arguments). This
4286 fixed a bug that caused problems when there were more than three
4289 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added extra parameter, command identifier, to the
4292 silc_client_send_command so that explicit command identifier
4295 Changed that ID list routines uses specific command identifier
4296 when sending WHOIS/IDENTIFY requests to the server so that they
4297 can be identified when the reply comes back.
4299 Affected files lib/silcclient/command.[ch],
4300 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4302 * Added `sender' argument to silc_server_packet_send_to_channel
4303 to indicaet the sender who originally sent the packet to us
4304 that we are now re-sending. Ignored if NULL. Affected file
4305 silcd/packet_send.[ch].
4307 * Added some server statistics support in silcd/server_internal.h
4308 SilcServerStatistics structure and around the server code. Also
4309 send some nice statistics information when client is connecting
4312 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Fixed channel ID decoding in server's JOIN command reply in
4315 silcd/command_reply.c
4317 * Fixed braodcasting of replace ID payload to not to send it if
4318 we are standalone server in silcd/packet_receive.c.
4320 * Fixed all channel message sending routines to not to send
4321 packets to clients that has router set, since they are routed
4322 separately in the same function earlier. Affects file
4323 silcd/packet_send.c and all channel packet sending functions.
4325 * In USERS reply, res_argv[i] are not allocated, the table
4326 is allocated. Thus changed that free the table, not its
4329 * In server's whois_check and identify_check if the client is
4330 locally connected do not send any WHOIS commands - they are not
4333 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Fixed some minor bugs in client when sending WHOIS command. The
4336 arguments was in wrong order.
4338 * Removed statis function add_to_channel from server in
4339 silcd/command.c that was previously used with the joining but
4342 * Tested USERS command in router environment successfully with two
4343 routers, two servers and two clients.
4345 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Reorganized the USERS command and command reply in client library
4348 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4349 When the command is given by user we register a pending command
4350 callback that will reprocess the command after the reply has been
4351 received from the server. When reprocessing the packet we then
4352 display the information. Thus, the USERS information is displayed
4353 now in the command callback instead of in the command reply
4354 callback. The processing of the command is same as previously
4355 when server has sent the command reply in the JOINing process.
4357 * Added to USERS command in silcd/command_reply.c to join the client,
4358 we didn't use to know about, to the channel after we've created
4359 a client entry for it. Also, for clienet we did know already still
4360 check whether it is on the channel or not and add it if not.
4362 * Removed silc_server_command_join_notify as the function and its
4365 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Changed the client's pending command handling to the same as the
4368 server's pending command handling. It is also now possible to
4369 execute command reply functions from other command reply
4370 function as the function callbacks for commands and command
4371 replies are one and same. The pending commands are not static
4372 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4373 in client connection context. Thus, pending commands are server
4374 connection specific as it is convenient.
4376 Changed the function silc_client_command_pending and
4377 silc_client_command_pending_del and added new function
4378 silc_client_command_pending_check. Removed the
4379 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4382 * Added cmd_ident, current command identifier, to the client
4383 connection context in lib/silcclient/client.h to keep track on
4384 command identifiers used in command sending. Client's command reply
4385 function handling now supports the mandatory command identifiers.
4387 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4388 funtions in client to fully support pending command callbacks.
4390 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4391 as one of the arguments to the application in the command reply
4394 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4395 before first releasing SILC but came back. Now it is removed again
4396 and should come back nomore. The FORWARDED flag was used only
4397 by the JOINing procedure by forwarding the command packet to router.
4398 Now, the JOINing procedure has been changed to more generic (due
4399 to various router environment issues) and FORWARDED is not needed
4400 anymore for anything. The protocol specification is yet to be
4403 Now, removed silc_server_packet_forward from server and the flag
4404 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4406 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Renamed NAMES command to USERS command. The NAMES was named that
4409 due to historical reasons. Now it is renamed. Also, rewrote
4410 parts of the USERS command. The nickname list is not sent anymore
4411 by the server. Only Client ID and mode lists are sent in the USERS
4412 command. Changed this also to the protocol specification.
4414 The client now resolves the names and stuff after it receives
4415 the USERS list from the server when joining to the channel.
4417 * WHOIS and IDENTIFY commands has been changed to support multiple
4418 Client ID's per command. One can now search for multiple users
4419 in the network by sending only one WHOIS or IDENTIFY command.
4420 Changed the code and the protocol specifications.
4422 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4423 uses silc_server_command_whois_parse to parse the request. */
4425 * If normal server, do not parse the WHOIS and IDENTIFY requests
4426 before sending it to the router. Saves some time.
4428 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Fixed JOIN command on client library. Wrong number of arguments
4431 used to crash the client.
4433 * Added silc_server_channel_has_global function to check whether
4434 channel has global users or not.
4436 * Added silc_server_channel_has_local function to check whether channel
4437 has locally connected clients on the channel.
4439 * The silc_server_remove_from_one_channel now checks whether the
4440 channel has global users or not after given client was removed from
4441 the channel. It also checks whether the channel has local clients
4442 on the channel anymore. If it does not have then the channel entry
4443 is removed as it is not needed anymore.
4445 * The silc_server_notify now checks on JOIN notify whether the joining
4446 client is one of locally connected or global. If it is global then
4447 the channel has now global users on the channel and that is marked
4448 to the channel entry. Also, it now saves the global client to
4449 global list who is joining and JOINs it to the channel. This is
4450 for normal server, that is.
4452 Changed silc_server_send_notify_on_channel,
4453 silc_server_packet_relay_to_channel and
4454 silc_server_packet_send_to_channel check if we are normal server
4455 and client has router set (ie. global client) do not send the
4456 message to that client, as it is already routed to our router.
4458 * Implemented LEAVE notify type handling in silc_server_notify
4461 * Tested LEAVE command in router environment successfully. Tested
4462 with two routers, two servers and two clients.
4466 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4468 * Implemented SIGNOFF notify type handling in silc_server_notify
4471 * silc_server_remove_id now removes the client entry from all channels
4472 it has joined and thusly sends SIGNOFF notify type.
4474 * Rewrote the NAMES list generation in server by removing two excess
4475 loops. The lists are created now inside one loop.
4477 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * silc_server_remove_channel_user checks now also global list
4480 for channel and client.
4482 * silc_server_new_channel_user checks now both local and global
4483 list for channel and client. Fixed a bug in client id decoding.
4484 Used to decode wrong buffer.
4486 * silc_server_channel_message checks now both local and global
4487 list for channel entry.
4489 * Tested channel joining (hence JOIN) in router environment
4490 successfully. Tested with two routers, two servers and two
4493 * Tested channel message sending in router environment successfully.
4495 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Added silc_server_save_channel_key into server.[ch] to save the
4498 received channel key in Channel Key payload processing. It is
4499 also used in JOIN command reply handling.
4501 Equivalent function silc_client_save_channel_key added into
4502 client.[ch] into client library.
4504 * Changed JOIN command reply to send information whether the channel
4505 was created or not (is existing already) and the channel key
4506 payload. Changed protocol specs accordingly.
4508 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4509 the request was sent by ID and not by nickname. Crashed on
4512 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4515 now correctly save the received data.
4517 * silc_server_free_sock_user_data now notifies routers in the
4518 network about entities leaving the network.
4520 At the same time implemented functions silc_server_remove_id
4521 and silc_server_send_remove_id to receive and send REMOVE_ID
4522 packets. The packet is used to notify routers in the network
4523 about leaving entities. The ID removed will become invalid in
4526 * Added function silc_idlist_del_server into server. Removes and
4527 free's server entry from ID list.
4529 * silc_server_private_message function now checks, if we are router,
4530 that the destination ID really is valid ID, naturally.
4532 * In router when NEW_ID packet is received (for new client) the
4533 hash of the Client ID is saved in the ID Cache but the
4534 client->nickname is set to NULL, instead of putting the hash
4537 IDENTIFY command now also checks that client->nickname must be
4538 valid. If it is not if will request the data from the server who
4539 owns the client. Added new function
4540 silc_server_command_identify_check.
4542 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4543 to set the command to already allocated Command Payload.
4545 * Tested private message sending in router environment with two
4546 routers, two servers and two clients. Fixed minor bugs and now
4549 * Fixed segfault from client's NAMES command. Used to crash if
4552 * Forwarded packets must not be routed even if it is not destined
4553 to the receiver. Changed server code comply with this.
4555 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Added `require_reverse_mapping' boolean value to ServerParams
4558 structure. If TRUE (not default) the server will require that
4559 the connecting host has fully qualified domain name.
4561 If the reverse mapping is not required and hostname could not be
4562 found the IP address is used as hostname.
4564 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Implemented version string checking to both client and server.
4567 The check is incomplete currently due to the abnormal version
4568 strings used in development version of SILC.
4570 * Changed all command functions in server to use the new
4573 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Changed char *data to unsigned char *data in ID Cache system to
4576 support binary data as ID Cache data. Changed code to support
4577 binary data in lib/silccore/idcache.c.
4579 * Renamed silc_server_packet_relay_command_reply to
4580 silc_server_command_reply as it is normal packet receiving
4581 function. Rewrote the function to accept command replys for
4582 servers and not only for clients.
4584 * Mark remote router always as registered server if we are connecting
4585 to it. Otherwise, commands sent by the router to us are ignored.
4587 * All ID List find routines now returns the ID Cache Entry pointer
4588 as well if requested.
4590 * WHOIS command works now in router environment, tested with two
4591 routers, two servers and two clients.
4593 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4594 in router environment (as it is almost equivalent to WHOIS) but
4595 hasn't been tested thoroughly. Added new functions:
4597 silc_server_command_identify_parse
4598 silc_server_command_identify_send_reply
4599 silc_server_command_identify_from_client
4600 silc_server_command_identify_from_server
4602 * Disabled route cache adding because adding two different ID's with
4603 same IP replaces the old cache entry thus giving wrong route.
4604 The entry->router->connection is always the fastest route anyway
4605 so route cache may not be needed. Of course, new routes maybe
4606 established after receiving the ID when the entry->router->connection
4607 might not be anymore the most optimal.
4609 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Add route cache for received ID for fast routing.
4613 * Added silc_server_packet_route to route received packet on router
4614 that is not destined to us.
4616 * Renamed silc_server_get_route to silc_server_route_get.
4618 * Added id_string and id_string_len fields into SilcServer to
4619 include encoded ServerID for fast comparing without excess
4620 encoding of the ID's.
4622 * Cleaned up WHOIS command on server side. Added following static
4625 silc_server_command_whois_parse
4626 silc_server_command_whois_check
4627 silc_server_command_whois_send_reply
4628 silc_server_command_whois_from_client
4629 silc_server_command_whois_from_server
4631 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4632 arguments in command replies. All command functions should be
4633 updated to use this macro.
4635 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Minor typo fixes on command reply handling on server.
4639 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added silc_server_command_add_to_channel internal routine to add
4642 the client to the channel after router has created the channel and
4643 sent command reply to the server.
4645 * Added generic silc_server_send_command to send any command from
4648 * Use static buffer with ID rendering instead of duplicating data.
4650 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Fixed a channel user mode bug when joining to a channel server gave
4653 everybody channel founder rights, oops.
4655 * We mark ourselves as the router of the incoming server connection
4656 if we are router ourselves. This way we can check in some packet
4657 sending functions whether it is locally connected server. For
4658 incoming router connections we put NULL.
4660 * For router sending packets locally means now always sending the
4661 packet cell wide; to local clients and local servers. For normal
4662 server sending packet locally means sending it to only local
4665 * Fixed the JOIN command to really work in router environment. If the
4666 channel is created it is always created by the router. Router is
4667 also responsible of making the initial joining to the channel,
4668 sending JOIN notify to the sending server and distributing
4669 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4670 does not exist server doesn't do anything else but forward the
4671 command to the router which performs everything.
4673 * Added silc_server_send_channel_key function to send the Channel Key
4676 * Added silc_server_create_channel_key to create new channel key. The
4677 channel key is now re-generated everytime someone joins or leaves
4678 a channel, as protocol dictates. Note: channel->key_len is the
4681 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4684 packet_receive.[ch] to separate packet sending and receiving
4685 routines. The server.[ch] now includes everything else including
4686 actual packet processing (writing and reading data) and other
4689 Renamed silc_server_private_message_send_internal to
4690 silc_server_send_private_message. The routine is still though
4691 used only to relay private messages as server does not send
4692 private messages itself.
4694 Renamed silc_server_new_channel to silc_server_create_new_channel
4695 and added new function sicl_server_new_channel that handles the
4696 incoming New Channel packet. Added also new sending function
4697 silc_server_send_new_channel to send New Channel Payload.
4699 * Added new function silc_server_notify to process incoming notify
4700 packet to the server/router. Server may then relay the notify
4701 to clients if needed.
4703 * Added new function silc_server_new_channel_user to process incoming
4704 New Channel User packet. Router will redistribute the packet and
4705 send JOIN notify to its local clients and locally connected servers
4706 if needed. Normal server will send JOIN notify to its local client
4707 on same channel when received this packet. Added also corresponding
4708 sending function silc_server_send_new_channel_user to sent the
4711 * Added boolean route argument to send_notif_to_channel and
4712 packet_send_to_channel functions to attempt to route the packet
4713 if it is TRUE and send only locally if it is FALSE.
4715 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * silc_server_replace_id now broadcasts the received replace ID
4718 packet if it is not broadcast packet already. The router must
4719 broadcast to inform other routers about changed ID.
4721 * Added backpointer to server's router into SilcServer context in
4722 silcd/server_internal.h.
4724 * Fixed silc_server_packet_broadcast to send correct broadcast
4727 * The channel key is now distributed to the local client as soon
4728 as it is received from the router (in router environment) so that
4729 no other packet may be sent for the channel until client has
4732 * silc_server_remove_channel_user now broadcasts the received
4733 Remove Channel User packet if it is not broadcast packet already.
4734 The router must broadcast to inform other routers about removed
4737 * Added users field into SilcPacketContext that is a reference count
4738 of the context. One can increase the reference count by calling
4739 silc_packet_context_dup which is now changed to just increase the
4740 reference count instead of duplicating the data. The reference
4741 count is decresed by calling silc_packet_context_free that will
4742 free the data after the reference count hits zero.
4744 For now on the packet context and everything allocated into it
4745 (including the raw packet from network) must be freed by calling
4746 the new silc_packet_context_free function. Added also new function
4747 silc_packet_context_alloc that must be used now to allocate the
4748 context. This also means that if a routine is asynchronous from
4749 silc_[client/server]_packet_parse_type the packet context must
4750 be duplicated by calling silc_packet_context_dup. Otherwise it
4751 gets free'd after silc_[client/server]_packet_parse_type returns.
4752 Also, one must remember that if packet is duplicated then its
4753 reference count must be decresed by calling the free function as
4754 many times as it was duplicated.
4756 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4757 from both client and server.
4759 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Made joining to a channel working in router environment.
4763 * Cleaned up JOIN command on server side and create function
4764 silc_server_command_join_channel internal routine to make the
4767 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Changed silc_command_pending list to SilcDList. Also, added
4770 `ident' field to SilcServerCommandPending structure to identify
4771 the reply and to call correct callback.
4773 Added silc_server_command_pending_check function to replace the
4774 corresnponding macro. The silc_command_pending list is not
4777 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4778 to set identifier to previously allocated Command Payload. It
4779 is used to set identifier for command when resending Command
4782 * Added silc_command_payload_encode_payload to encode Command
4783 Payload buffer from SilcCommandPayload structure.
4785 * Added silc_argument_payload_encode_payload to encode Argument
4786 payload buffer from SilcArgumentPayload structure.
4788 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Changed WHOIS command to support router connection on server side.
4791 The whois request is always sent to router unless the server is
4792 standalone server. After server has received the reply from the
4793 router will it send the reply to the client.
4795 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4796 broadcast received broadcast packet. The function is used only
4797 by router. The broadcast packet is always sent to the router's
4800 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4801 render given ID to printable string, for log files for example.
4803 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Made basic router to router connections working. At least they
4806 can now connect to each other but nothing really works the way
4807 they are supposed - yet.
4809 * Added new initiator token to RouterConnection configuration
4810 file in silcd/serverconfig.[ch]. It is used to tell whether we
4811 are the initiator to the remote router or whether we'll expect
4812 the other end to connect.
4814 * Moved registering of listener task to silc_server_init, hence
4815 the server starts listenning as soon as it is run, even if it
4816 does not have connections to other routers. Let's see how well
4819 * Changed default connection retry timeouts for more suitable in
4822 * Removed cipher and such arguments from silc_idlist_add_client
4823 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4824 Added new function silc_idlist_add_data to add the keys and stuff
4827 * Added SilcIDListData structure and added it to SilcClientEntry
4828 and SilcServerEntry as their first field in the structure. This
4829 way we can explicitly cast the ID entries to the SilcIDListData
4830 structure and get common data for the entries. In past, we had
4831 to first check what type of connection it is and then cast it to
4832 correct ID entry type. Now, we can directly cast the opaque
4833 pointer to the SilcIDListData (no matter what ID entry it actually
4834 is) and get the data needed.
4836 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4839 in some circumstances even if threre were timeout tasks, though not
4840 IO tasks, but tasks anyway. Now fixed.
4842 * Defined SilcServerConnection structure to hold connection specific
4843 stuff about directly connected servers and routers. The definition
4844 is currently in silcd/server_internal.h. I thought about having
4845 a bit more important role fro this struct but for now it is used
4846 only when connecting to other server (or router actually).
4848 * Added connecting retry support in server when connecting to
4849 router(s). The retry feature implement exponential backoff
4850 algorithm. Also, added SilcServerParams structure to hold default
4851 parameters for server. For now, it include these retry settings
4852 and are hard coded. After server is moded to be as Silc Server
4853 Library this structure will be more important.
4855 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Changed client librarys channel->clients table to SilcList and
4858 changed code accordingly.
4860 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Changed client's channel table to SilcList and changed code
4863 accordingly. Also changed SilcChannelClientEntry to include back-
4864 pointer to the channel so that client entry can use that structure
4865 as list as well and we have fast cross-reference to the channel.
4866 This change dramatically decreased the complexity of channel
4867 handling with client entry and vice versa (removed one extra
4868 loop when searching for channel entry from many functions).
4870 * Changed server->sim from table to SilcDList and changed code
4873 * NAMES command can now be used from user interface. It will show
4874 the user list on the channel, neatly.
4876 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4877 Code now saves realname of the user if it becomes available.
4879 * Renamed configure.in to configure.in.pre and made ./prepare
4880 script to automatically add correct version string to
4881 configure.in which it creates from configure.in.pre.
4883 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * NAMES command reply now shows users mode with the nickname when
4888 * Moved silc_client_ch[u]mode[_char] functions from
4889 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4890 place sucks, they are utility functions and should be in some
4893 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4895 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4898 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added TRQ (efficient deque and list library) into lib/trq. This is
4903 a very good list library that is currently used in the SILC. Defined
4904 SilcList API over the library because I didn't like the API very
4905 much. See lib/trq/silclist.h for the API and examples of how to
4906 use the API. Fixed various places in the code to use the new
4907 SilcList API. The SilcList is meant for lists that has a structure
4908 already defined as a list. It is not suitable to add just some
4909 context to the list (in TRQ, the context is the list actually).
4911 So, I defined SilcDList that can be used for the purpose where
4912 predefined list structure does not exit. This can be used as
4913 such list. Now some context just can be added to the SilcDList.
4914 Currently this list is not used in the SILC just yet, though there
4915 are a lot places where this can replace dynamically allocated
4916 tables and I will fix these places, later, to use SilcDList.
4917 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4918 and use TRQ internally).
4920 Also fixed some annoying warning messages that the original TRQ
4921 code generated. Also minor changes to TRQ's Makefile.in.
4923 * Added support for querying by Client ID to both WHOIS and
4924 IDENTIFY commands into server, as required by the protocol.
4926 * Removed method function pointers from SilcBuffer structure. They
4927 weren't used to anything and just increased the context size for
4928 no good reason. This change also made silc_buffer_alloc and
4929 silc_buffer_free functions inline functions.
4931 * Disabled command flooding detection support until it's fixed so
4932 that it accepts commands in but does not execute them more than once
4935 * Added silc_net_localhost(), to return local hostname, into
4936 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4937 that must be initialized before calling silc_client_init.
4939 * Added new function: silc_server_send_notify_on_channels to send
4940 notify messages to all channels client has joined. It is assured
4941 that the message is sent only once per client.
4943 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4944 lib/silcutil/silcutil.[ch] as silc_format function. The new
4945 function is generic and is used by server as well, not only by
4946 the logging routines.
4948 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4949 the provided version string was not acceptable. Added new function:
4950 silc_ske_check_version into lib/silcske/silcske.h. The function
4951 must be implemented by the application (client or server) and it
4952 does not reside in the SKE library. The function checks the version
4953 string remote end sent.
4955 * Added back pointers (to opaque context and to SilcSocketConnection)
4956 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4958 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4959 duplicate packet context structure.
4961 * Changed `notify' client operation to send same arguments as client
4962 receives from server except for ID's. ID's are mapped to correct
4963 ID entry and that is returned. Also, if channel entry is not sent
4964 by server but the notify is for channel the channel entry is sent
4965 to application (otherwise application doesn't know that it is for
4966 channel (library gets it from packet's Destination ID)).
4968 * Added silc_client_remove_from_channels into client library to
4969 remove a client from all channels it has joined to. Used when
4970 received SIGNOFF notify from server. Added also new function
4971 silc_client_replace_from_channels to replace old ID entry with
4972 new ID entry on all channels. Used when received NICK_CHANGE
4975 * Fixed ID Cache list handling in silc_idlist_get_client in
4976 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4977 to get (or query) client by ID.
4979 * Updated TODO list.
4981 * Added connection authentication status message defined by the
4982 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4983 support for these into the code in client and server side.
4985 * Added generic function silc_client_send_command to send any command
4986 with variable argument list. Application should use this function
4987 to send commands if the command functions provided by the library
4988 does not suite for the application's user interface needs.
4990 * Added new `failure' client operation. Application is notified about
4991 received failure packet if client is executing a protocol. In this
4992 case the protocol's execution has failed.
4994 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4995 is required by the protocol.
4997 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4998 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5001 * Added status flag to SilcSKE object to indicate realtime status
5002 of the SKE protocol.
5004 * Application receives now exactly same command reply arguments as
5005 the library receives from server. However, if ID is received the
5006 corresponding ID entry is returned to the application (eg. Client
5007 ID is mapped to correct SilcClientEntry entry and that is returned).
5008 Changed command_reply client operation due to this change.
5010 * Changed all ID's in commands and in command replys as ID Payloads.
5011 Change affected both client and server side codes.
5013 All ID's sent in SILC network (with execption of ID's in SILC
5014 Packet header) are sent in ID Payload to support variable length
5017 * Server now notifies nick changes and notifies all clients on
5018 the channels about the new nickname (about the new Client ID,
5021 * Implemented CMODE command to change channel modes. Supports all
5022 channel modes defined by the protocol specs except ban and invite
5023 lists. (Also, private channel key mode is supported but support for
5024 setting private channel key in client is missing, thus, this mode
5025 has no effect on client side (except that server requires that the
5026 client uses private channel key and normal channel traffic does not
5029 Also, invite mode works per se, but INVITE command does not work
5030 yet correctly, so you can set channel as invite only channel but
5031 inviting clients to the channel does not work (it is yet to be
5032 thought what's the best way to do it).
5034 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5035 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5036 Implemented CUMODE command to change user's mode on the channel.
5037 Supports all modes defined by the protocol specs.
5039 * Added NAMES command reply to return users modes on the channel.
5041 * Removed unnecessary and slow ciphers from lib/silccrypt.
5043 * Set SO_KEEPALIVE option to connection sockets by default.
5045 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5047 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5048 redefined the Notify Payload into protocol specs.
5050 * Added silc_id_payload_parse_id to get ID directly from raw
5053 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5056 accept searching by Client ID as well.
5058 * Added support for LEAVE and SIGNOFF notify types in client library.
5060 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5061 to parse ID Payload from raw data.
5063 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Added flags parameter into silc_ske_assemble_security_properties
5066 function in lib/silcske/silcske.[ch].
5068 * Changed notify client operation to fit better for notify messages
5069 sent by server. The notify payload received from server is now
5070 passed to the application (after parsing it to SilcNotifyPayload).
5071 It is application's responsibility to retrieve the arguments
5072 from the payload and show the message the way it wants. The message
5073 sent by server is implementation specific.
5075 * Changed public keys to comply with the protocol specification.
5076 Old public keys are not supported anymore and are not compatible.
5078 * Removed nickname from Channel Payload as the latest draft removed
5079 it. The client must resolve the nickname from the NAMES command
5080 reply received when it joined the channel.
5082 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5084 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Fixed some errors in protocol specification drafts.
5088 * Created lib/silccore/silcnotify.c to implement Notify Payload
5089 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5090 generic payloads described by protocol specifications. The file
5091 includes implementations for ID Payload and Argument Payload.
5093 * Changed Command Payload implementation to use the new Argument
5094 Payload. Changed command_xxxx_payload to command_payload_xxxx
5095 to comply with SILC coding conventions.
5097 * Added suppport for Argument Payload handling in Notify Payload
5098 implementation as protocol requires it. Added the new support
5099 into server and client lib as well.
5101 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Added support for multiple nicknames on same channel. [n] is
5104 added locally to the nickname if there are more than one same
5105 nicknames on the channel.
5107 * Server now sends all nicknames that matched WHOIS request.
5108 Client also shows the list received from server.
5110 * Added TOPIC command to client side. User can now set and show
5111 current topic on channel.
5113 * Added MOTD command to client and server. Also, server sends the
5114 motd when client connects to the server.
5116 * Changed version strings to comply ISO 8601.
5118 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Fixed protocol error handling in client library. It should now
5121 cope even if the SKE fails for some reason.
5123 * Made new protocol specification drafts for submitting to IETF.
5125 * Implemented TOPIC command to server in silcd/command.c.
5127 * Added two new notify types into lib/silccore/silcnotify.h:
5128 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5129 notify nickname change and topic setting/change on a channel.
5131 * API change of command_reply operation in client library. The
5132 application gets now the status type received from server as well.
5134 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5138 * Cras fixed and optimized the packet handling even further and
5139 it should work now. Minor change to the prototype of function
5140 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5142 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added new function into lib/silcutil/silcschedule.[ch]:
5145 silc_schedule_with_fd to select() a specified fd. The function
5146 returns after timeout expires or data arrives or goes. The
5147 function is used by packet routines to wait that all data is
5148 received from network.
5150 * Fixed data reading from network in lib/silccore/silcpacket.c.
5151 The code now assures that all data is read from the fd and then
5152 continues packet processing. This was a bug fix since the code
5153 used to drop some data in some circumstances.
5155 * Added new function into lib/silcclient/client.[ch]:
5156 silc_client_start_key_exchange to start key exchange after
5157 connection has been established to server. The code internally
5158 now uses this funtion but its main purpose was to provide it
5159 for applications that perform their own connecting. After
5160 application has created a connection it merely calls this
5161 function to start the key exchange between client and server.
5162 The library takes care of everything else after that.
5164 Updated also lib/silcclient/README to explain the usage of
5167 * Do not send to application information that connection has
5168 been established. Application gets notified it by connect
5171 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Applied cras's patch to add silc_schedule_one function. The
5174 function runs scheduler once and returns.
5176 * Fixed the scheduler after cras messed it up. The timeout
5177 handling works now as it's supposed to work.
5179 * Added into lib/silccore/ silcnotify.h to include notify
5180 message types support. Changed silc_server_send_notify*
5181 functions, in server.[ch], to support those new notify types.
5182 Added the support for the notify types into client library,
5183 as well. Added new notify client operation into ops.h in
5186 * Changed silc_server_packet_send_to_channel to send normal
5187 packets instead of just channel message packets. The function
5188 is now used to send the notify packets to channels. It is not
5189 used to send channel message packets anymore, as server never
5192 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5193 va_arg()s as it seems to require it nowadays. I guess, if SILC
5194 is compiled with older va_arg() the new code should work anyway.
5196 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Splitted core library. Core library (lib/silccore) includes
5199 now only SILC protocol specific core (and common) components.
5200 Created new utility library (lib/silcutil) that includes more
5201 generic purpose stuff. The stuff for util library was taken
5202 from the old core library. This was minor and easy split.
5204 * Created SILC Client Library (lib/silcclient) that includes
5205 implementation of the SILC client without user interface. This
5206 was major move from silc/ directory. The code has been changed
5207 so that it is transparent towards the user interface. The
5208 silc/ directory includes now the same user interface as before
5209 and it uses the new client library. Read lib/silcclient/README.
5210 Basicly, the client library performs everything else related
5211 to SILC except user interface handling. Also, configuration
5212 files are considered to be part of user interface and library
5213 does not handle them.
5215 This change also changed a lot of structures, function naming etc.
5216 Most important change was that SilcClientWindow object was
5217 renamed to SilcClientConnection in the client library. Created
5218 also new file lib/silcclient/ops.h. Also added new files
5219 silc/local_command.[ch] and silc/client_ops.[ch].
5221 All these changes were made to make it easier for user interface
5222 designers to create what ever user interface for the SILC client
5225 It is also expected that the server will be moved to lib
5226 directory as well and SILC Server Library will be created;
5227 sometimes in the future.
5229 * Removed Local commands from lib/silccore/silccommand.h as
5230 they are application specific and new client library does not
5231 handle any of those anymore.
5233 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5234 old client implementation in silc/.
5236 * Added support for callback functions in SILC_LOG_* macros.
5237 Application can now set its own callbacks that will be called
5238 instead of using the default functions that will always print
5239 the debug messages to stderr (or stdout). Also, debugging can
5240 now be disabled by setting silc_debug to FALSE and re-enabled by
5241 setting it to TRUE. Note, that logging will still work even
5242 if debugging is disabled.
5244 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5245 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5246 silc_log_reset_debug_callbacks.
5248 * To enable debugging in silc client one must give now -d
5249 option on command line.
5251 * Changed silc_schedule_init to automatically allocate task queues
5252 if they are not allocated before calling it.
5254 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added GMP 3.1 into math library.
5258 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5261 a channel in SILC network. The packet is used by servers and
5262 routers to notify other routers that user has left a channel.
5263 This little feature was missing until now. Added the feature
5264 to protocol specification as well.
5266 Added functions: silc_server_send_remove_channel_user and
5267 silc_server_remove_channel_user into server.[ch].
5269 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5270 lib/silccore/silcpacket.h. However, they are not implemented
5273 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Fixed joining to a channel and sending channel messages
5276 between server and router. The channel message sending should
5277 now work inside a cell.
5279 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Fixed the private message sending between server and router.
5282 The private message sending should now work inside a cell.
5284 * Added silc_server_replace_id into server.[ch] to replace
5285 existing ID in the SILC network.
5287 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5288 and silc_idlist_replace_server_id into idlist.[ch] in server.
5290 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Fixed the server to server connections. Server can again now
5293 connect to router. Router to router connections probably does
5296 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Added dynamic protocol registering support. Now protocols can
5299 registered and unregistered on the fly. Patch by cras.
5301 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Added lib/contrib directory to hold routines that some platforms
5304 don't have but are needed by SILC.
5306 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5307 into lin/contrib to provide getopt() and getopt_long() for
5308 those who don't have it.
5310 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added AWAY command to client. When away message is set and
5313 client receives a private message packet the client automatically
5314 replies to the sender with the away message.
5316 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5317 bug seemed to be the cause of recent problems when compiling
5320 * Added version detection support to SKE protocol specification
5321 and added the new changes to the SKE implementation as well.
5322 There were other minor changes in the SKE protocol as well.
5324 Many changes in lib/silcske/silcske.[ch] and in
5325 lib/silcske/payload.[ch].
5327 * Added ^U functionality, clear input line. Patch from cras.
5329 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Mainly small bugfixes on core library. Fixed some debugging
5332 logging and buffer overflow in silclog.c.
5334 * Updated config.sub and config.guess on the distribution tree.
5336 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Added command lagging support in server. Client may execute
5339 commands now only once in two seconds.
5341 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Optimized packet reception. MAC computation and checking is now
5344 also more optimized. A lot previously duplicated code is now
5345 used as generic by both client and server.
5347 * Fixed key pair generation in clientutil.c
5349 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Added into lib/silccore/silcbufutil.[ch] new function;
5352 silc_buffer_realloc.
5354 * Moved generic packet sending/encryption functions to
5355 lib/silccore/silcpacket.[ch] from client and server. Some
5356 rewriting of the functions.
5358 * Moved all generic packet reception/decryption functions to
5359 lib/silccore/silcpacket.[ch] from client and server. The
5360 packet processing is now much cleaner in both client and server.
5361 These were major changes in both client and server.
5363 * Created many common functions in server to do packet sending.
5364 Previously code were duplicated a lot, this has been removed
5367 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Rewrote major parts of the ID cache system. Don't know
5370 whether it is better now or not but at least the API is more
5373 * Major rewrite on ID cache stuff on client because of the ID
5374 cache API changes. Added idlist.c to client.
5376 * Also major rewrite on ID cache stuff on server as well.
5377 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5378 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5379 in hand, instead they are all put into the ID cache system now.
5380 All server_idlist_* routines uses ID cache now instead of
5381 traversing its own lists (those lists does not exist anymore).
5382 SilcIDList though still exists. Also, SilcXXXEntry's are
5385 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Finally made the SKE implementation compliant to the protocol
5388 specification. All mp integers are now binary encoded as
5389 opposed being HEX encoded.
5391 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5394 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5395 functions: silc_[encode/decode]_pem. Also added function
5396 silc_encode_pem_file to PEM encode with newlines ('\n') for
5399 * SILC public keys are now encoded either PEM or binary. Same
5400 option is for private keys as well. By default private keys
5401 are binary encoded and public keys PEM encoded. Silly HEX
5402 encoding were removed.
5404 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5405 function to create fingerprints.
5407 * Fixed a bug in SHA1; does not change the original data anymore.
5409 * Partly implemented INFO command on client and server side.
5410 Fixed CLEAR command. Changes to SERVER command; show current
5411 server(s) when giving command without arguments. Added
5412 VERSION command to client.
5414 * Added check to server that unregistered connections cannot
5415 execute commands (unless it is specificly allowed).
5417 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Fixed screen refresh.
5421 * Fixed channel joining bug from client. On some circumstances
5422 client tried to join to a channel it had already joined.
5424 * Added public key verification process into client's protocol.c.
5425 The client now verifies the public key from user and saves
5426 it into ~./silc/serverkeys/ directory.
5428 Added into: clientutil.[ch]: silc_client_verify_server_key.
5430 * Changed SKE protocol's silc_ske_initiator_finish function
5431 to accept callback function that verifies the received public
5432 key. Removed old silc_ske_verify_public_key function.
5434 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5437 silc_pkcs_private_key[_data]_set.
5439 * Made the password and public authentication more cleaner in
5440 server's protocol.c.
5442 * Removed historic and obsolete protocol `channel_auth' from
5443 both client and server.
5445 * Removed wrong way of sending command status messages from
5446 server to client in server's command.c. The old way violated
5447 protocol specification.
5449 Changes to silccore/silccommand.[ch]: removed
5450 silc_command_encode_status_payload -> not needed anymore,
5451 changed silc_command_encode_payload_va to accept extra
5452 argument on variable argument list. The argument type must
5453 now be provided to the function. Also, added new function:
5454 silc_command_encode_reply_payload_va which is same as
5455 normal command_encode_payload_va except command status type
5456 is provided as extra argument.
5458 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Added ~./silc directory handling. The directory includes the
5461 public and private keys for the client.
5463 Added silc_client_check_silc_dir, silc_client_create_identifier
5464 and silc_client_load_keys.
5466 * Implemented SILC protocol compliant public key. Added public
5467 and private key saving to and loading from files.
5469 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5470 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5471 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5472 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5473 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.

5480 * Added silc_server_get_route (route.[ch]) to get connection
5481 data for the fastest route for given ID.
5483 * Implemented INVITE command on client and server. The command
5484 were re-defined in the SILC Protocol Specification and the
5485 implementation now complies with the specification.
5487 * Implemented PING command on client and server.
5489 * Implemented NAMES command on client and server. The server side
5490 supports currently only normal server not router server yet.

5499 should not violate the protocol specification anymore.

5503 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
