1 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Check for existing server ID in silc_server_new_server
4 and in silc_server_connect_to_router_final and remove the
5 old entry if it exists. Affected file silcd/packet_receive.c,
8 * Send the channel message always to only one router, either
9 in upstream or downstream. Affected file is
12 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
14 * Wrote the definition of the backup resuming protocol to the
15 protocol specification.
17 * Removed one redundant channel key generation from normal
18 server during joining procedure. Removed one redundant
19 channel key sending from server to router during joining
20 procedure. Affected file silcd/command.c.
22 * Made minor bugfixes to the backup router resuming protocol.
23 Affected file silcd/server_backup.c, server.c.
25 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
27 * Added --disable-asm configuration option. Affected files
28 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
31 * Implemented the backup resuming protocol that is used to
32 resume the primary router position in the cell after the
33 primary router comes back online. Affected files
34 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
35 and silcd/server_util.[ch].
37 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Sleep two (2) seconds after sending QUIT command to server.
40 Affected file lib/silcclient/command.c.
42 * Assure that if outgoing data buffer is pending do not force
43 send any data. Affected file silcd/packet_send.c.
45 * Assure that if outgoing data buffer is pending do not force
46 send any data. Affected file lib/silcclient/client.c.
48 * Implemented the backup router support when the primary router
49 goes down. The servers and routers can now use the backup
50 router as new primary router without loosing connectivity.
52 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
54 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
55 in the server to indicate disabled entry. All data read
56 from the connection will be ignored and no data is sent
57 for entry that is disabled. Affected files are
58 silcd/idlist.h, silcd/server.c.
60 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Created SFTP client and server test programs in the
63 lib/silcsftp/tests directory.
65 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
67 * Implemented memory filesystem (virtual filesystem) for
68 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
71 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
73 * Implemented the SFTP (SSH File Transfer Protocol) to the
74 lib/silcsftp. It includes SFTP client and SFTP server
77 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
79 * Moved lib/silccore/silcprotocol.[ch] to the
82 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
83 take variable argument list pointer as argument. Affected
84 file lib/silcutil/silcbuffmt.[ch].
86 * Added silc_buffer_set function that is used to set data
87 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
88 Affected file lib/silcutil/silcbuffer.h.
90 * Changed various routines in the core library to use the new
91 silc_buffer_set instead of allocating new buffer only for
94 * Added 64-bit value formatting and unformatting support to the
95 silc_buffer_[un]format routines. Affected file is
96 lib/silcutil/silcbuffmt.[ch].
98 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
99 to includes/bitmove.h.
101 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Fixed channel user mode saving in client library. Affected
104 file lib/silcclient/command[_reply].c.
106 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
108 * Defined the file transfer to the SILC Protocol. Added
109 new packet type SILC_PACKET_FTP and defined File Transfer
110 Payload. The mandatory file transfer protocol is SFTP
111 (SSH File Transfer Protocol). Affected file in addition
112 of the internet draft is lib/silccore/silcpacket.h.
114 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
115 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
116 is used as part of backup router protocol when the primary
117 router of the cell is back online and wishes to resume
118 the position as primary router.
120 * Redefined the MAC generation keys in the protocol. The
121 same key is not used anymore in both direction. Both
122 direction will now use different keys for sending and
123 receiving. This fixes a potential security flaw. This
124 change causes incompatibilities in the protocol.
126 * Redefined also the MAC computation from the packet.
127 An packet sequence number is now added to the MAC
128 computation. This prevents possible replay attacks against
129 the protocol. This change too causes incompatibilities
132 Added `sequence' field to the SilcPacketContext to hold
133 the current sequence number for the packet.
135 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Added `created' field to the SilcIDListData in the file
138 silcd/idlist.h to indicate the time when the entry was
141 * Added `created' field to the SilcChannelEntry too. Affected
144 * Added `creation_time' aguments to all the announcement functions
145 in the server. If it is provided then only the entries that
146 was created after the provided time frame are actually
147 announced. Affected file silcd/server.[ch].
149 * The protocol says that the Channel ID's IP address must be
150 based on the router's IP address. Added check for this in
151 the silc_server_new_channel when processing incoming New Channel
152 Payload. Affected file silcd/packet_receive.c.
154 * Print out the correct version with --version in SILC client.
155 Affected file irssi/src/silc/core/silc-core.c.
157 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
159 * Fixed WHOWAS command to check for completnes of the client
160 entry always, not just when the command is coming from client.
161 Affected file silcd/command.c.
163 * Added new function silc_server_packet_queue_purge to purge the
164 outgoing data queue to the network. After the function returns
165 it is guaranteed that the outgoing packet queue is empty.
166 Affected file silcd/packet_send.[ch].
168 * Purge the outgoing packet queue in the rekey protocol's final
169 callback to assure that all rekey packets go to the network
170 before quitting the protocol. Affected file silcd/server.c.
172 * Added silc_client_packet_queue_parse as similar function as
173 in server to the client library. The affected file is
174 lib/silcclient/client.c.
176 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Splitted silcd/server.c and created silcd/server_util.[ch]
179 for utility functions.
181 * Added new socket flag SILC_SF_DISABLED to indicate that the
182 connection is open but nothing can be sent to or received from
183 the connection. Affected file lib/silcutil/silsockconn.[ch].
184 The checking for disabled socket is checked in the low level
185 silc_socket_write and silc_socket_read functions.
187 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
189 * Allow only nicknames and channel names that fits into the
190 7-bit unsigned char ASCII set. Affected file silcd/command.c.
192 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
194 * When processing JOIN command reply in server check that if
195 the channel exists in our global list we'll move it the local
196 list. Affected file silcd/command_reply.c.
198 * Fixed the check whether client is joined on the channel already
199 in JOIN command. Affected file lib/silcclient/command.c.
201 * Fixed the JOIN command reply to check whether the channel
202 already exists. Affected file lib/silcclient/command_reply.c.
204 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
206 * Added silc_ske_status_string to map the SKE error numbers
207 to readable strings. The affected files are
208 lib/silcske/silcske[_status].[ch].
210 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
212 * Do not show the private channels on the WHOIS channel list
213 as it is not allowed by the protocol. The affected file is
216 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Assure that the packet length digged from the actual packet
219 is something sensible in the silc_packet_decrypt_rest_special
220 in lib/silccrypt/silcpacket.c.
222 * Free and NULL the allocated pointer in silc_hmac_alloc if
223 the HMAC allocation fails. The affected file is
224 lib/silccrypt/silchmac.c.
226 * Print the selected security properties to the log files in
227 the server. Affected file silcd/protocol.c.
229 * Add SKE's reference counter even if calling the completion
230 callback manually. Otherwise it goes negative, although it
231 does not cause any problems. The affected file is
232 lib/silcske/silcske.c.
234 * Remove the client entry with short timeout after giving the
235 KILL command. Affected file lib/silcclient/command.c.
237 * Fixed to send error reply in WHOIS and IDENTIFY commands in
238 case all found clients are already disconnected (WHOWAS would
239 found them) in the server. Affected file silcd/command.c.
241 * Update the last_receive (time of last data received) to be
242 updated only when received private or channel message so that
243 the idle time showed in WHOIS makes more sense.
245 * Added boolean field `valid' in to the SilcClientEntry in the
246 client library to indicate whether the entry is valid or not.
247 This fixes the nickname change bug on channel when changing
248 the nickname to be same than the old (like nick to Nick) the
249 nickname formatter doesn't set the new nick anymore to Nick@host.
250 Affected file lib/silcclient/idlist.[ch].
252 * Now actually fixed the nickname changing on disconnection.
253 Added new function silc_change_nick to the Irssi SILC Client.
254 Affected file irssi/src/silc/core/client_ops.c,
255 irssi/src/silc/core/silc-nicklist.[ch].
257 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
259 * Check that the public key exists in the GETKEY command before
260 trying to encode it. Affected file silcd/command.c.
262 * Print some notifications on received public keys with GETKEY
263 command in the Irssi SILC Client. Affected files are
264 irssi/src/fe-common/silc/module-formats.[ch],
265 irssi/src/silc/core/client_ops.c.
267 * Use IDENTIFY command to resolve the server information in the
268 GETKEY command instead of INFO command. Affected file
269 lib/silcclient/command.c.
271 * All command reply functions in the client library now calls
272 the pending command reply callbacks even if an error has
273 occurred. The server has done this a long time and now it was
274 time to move the client library to this as well. Now all
275 errors can be delivered back to the pending command reply
276 callbacks if necessary. Affected files are
277 lib/silcclient/command[_reply].[ch].
279 * Change the nickname on disconnection back to the username
280 because in reconnect the server will enforce it to it anyway.
281 Affected file irssi/src/silc/core/silc-servers.c.
283 * Fixed a config file parsing bug in the Irssi SILC client.
284 Affected file irssi/src/silc/core/clientconfig.c.
286 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
288 * When printing the channel mode on JOIN, verify that the
289 channel key and channel's HMAC are valid. Affected file
290 irssi/src/silc/core/client_ops.c.
292 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
294 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
295 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
296 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
298 * Removed channel key rekey task deleting from the function
299 silc_server_save_channel_key. Affected file silcd/server.c.
300 Added explicit timeout task context instead that is used to
301 delete the task if we are registering a new task before the
302 new task has elapsed.
304 * When channel key rekey occurs the client library now saves
305 the old channel key for a short period of time (10 seconds) and
306 is able to use it in case some is still sending channel
307 messages encrypted with the old key after the rekey. Affected
308 file lib/silcclient/[idlist.h|client_channel.c].
310 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Added check to the silc_server_new_id_real to not accept
313 new ID if it is the sender's own ID. Affected file is
314 silcd/packet_receive.c.
316 * Assure that we do not announce ourself or the one we've
317 sending our announcements when we're router and are announcing
318 servers to our primary router. Affected file silcd/server.c.
320 * Fixed silc_server_command_identify_check_client to assemble
321 correct WHOIS packet. It send corrupted WHOIS packet and
322 caused problem with router to router connections. Affected
323 file silcd/command.c.
325 Fixed also silc_server_command_whois_check the same way
326 as for the IDENTIFY command.
328 * Added new SilcIDListStatus to the server in the SilcIDListData
329 structure. The status now includes the current status of
330 the entry (like registered, resolved etc.). Affected file
331 silcd/idlist.[ch]. Defined a bunch of different status types
332 as well. This replaced the old boolean registered field as well.
334 Added resolve_cmd_ident field to the SilcClientEntry structure
335 too so that if the entry is for example being resolved so
336 another command may attach to the same pending command reply
337 without requiring to resolve the same entry again. This concept
338 should optimize the WHOIS and the IDENTIFY resolving under
339 heavy load by taking away unnecessary resolving for entries
340 that are being resolved already.
342 Added support for adding multiple pending commands for one
343 command idenfier. Affected file silcd/command[_reply].[ch].
345 * Fixed WHOIS and IDENTIFY save to remove the cache entry
346 before deleting the data. Otherwise the hash table will have
347 freed data in comparison functions. Affected file is
348 silcd/command_reply.c.
350 * Fixed silc_idlist_replace_client_id to add the new entry to
351 the cache with NULL nickname. Otherwise there will be invalid
352 memory as the nickname after the nickname is freed. Affected
353 file silcd/packet_receive.c.
355 * Fixed the silc_idlist_get_clients_by_hash. The entries was
356 saved into wrong slots because the previous number of entries
357 was not taken into account. Affected file silcd/idlist.c.
358 Fixed same thing in silc_idlist_get_clients_by_nickname too.
360 * If we are router and we receive JOIN notify to a channel that
361 does not have any users then notified client is marked as the
362 channel founder, as it is it. The affected file is
363 silcd/packet_receive.c
365 * Added to the extended hash table API's table_del_*ext functions
366 the destructor as argument too, so that the caller can decide
367 which destructor to use or whether to use destructor at all.
368 Affected file lib/silcutil/silchashtable.[ch].
370 * Fixed ID Cache purging. It actually deleted the entries from
371 the hash table after the data was freed. The hash table ended
372 up comparing freed memory. The affected file is
373 lib/silccore/silcidcache.c.
375 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
377 * Fixed Irssi SILC client's KILL command's HELP syntax.
379 * The USERS command now resolves the detailed user information
380 if the userinfo field is missing. Affected file is
381 lib/silcclient/command_reply.c.
383 * Do not print error in silc_file_read if the read file does
384 not exist. Just silently return NULL. Affected file is
385 lib/silcutil/silcutil.c.
387 * Fixed the silc_log_output to not wine about NULL filename
388 and to not create some bogus " " filename. Affected file is
389 lib/silcutil/silclog.c.
391 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Fixed various printing bugs on the user interface in the
394 Irssi SILC Client. Minor changes that were forgotten from
397 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
399 * Fixed the configure.in.pre and the compilation and distribution
400 environment to support the new autoconf 2.52. That version is
401 now required to compile the CVS trunk.
403 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Renamed function silc_parse_nickname to silc_parse_userfqdn
406 to generally parse user@fqdn format strings. Affected file
407 lib/silcutil/silcutil.c.
409 * Added nickname_format and nickname_force_format fields to the
410 SilcClientParams structure. The first one defines the format
411 for the nicknames that the library will enforce if the receives
412 multiple same nicknames. The second one is boolean value and
413 can be used to force the library to always enforce the format
414 to the nicknames regardles whether there are multiple nicknames
415 or not. This configurable formatting was employed to flexibly
416 support accessing multiple nicknames from the user interface.
417 The userinterface can now set the nicknames to what ever format
418 they prefer. Affected file lib/silcclient/silcapi.h.
420 Added function silc_client_nickname_format to the file
421 lib/silcclient/idlist.c. It performs the nickname formatting.
423 Added new field `hostname´ to the SilcClientEntry context.
424 It holds the hostname of the client. Affected file is
425 lib/silcclient/idlist.h.
427 * Irssi SILC Client sets the nicknames in nick@hostn format.
428 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
429 irssi/src/silc/core/silc-core.c.
431 The WHOIS printing now also shows both the real nickname and
432 the formatted nickname so that user knows how to access the
433 user if there are multiple same nicknames cached. Affected
434 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
435 printing formatting too to take the hostname now as a separate
436 argument. The Affected file is
437 irssi/src/fe-common/silc/modules-formats.[ch].
439 * Changed the silc_client_get_clients_local to accept the formatted
440 nickname as argument. It accepts the real nickname too but the
441 formatted nickname can be used to find the true entry from
442 multiple entries. Affected file lib/silcclient/silcapi.h and
443 lib/silcclient/idlist.c.
445 * Added nickname_format_parse field to the SilcClientParams.
446 It is a callback function provided by the application to parse
447 the nickname out of the formatted nickname string. The library
448 calls it to get the nickname from the formatted string. Since
449 the application generally knows better the format of the nickname
450 string it parses it instead of the library, even though library
451 encodes the formatted string. If the callback function is not
452 provided then the library will use the string as is. The
453 affected file is lib/silcclient/silcapi.h.
455 * All the nickname strings passed to the client library in
456 commands are now expected to be formatted nickname strings.
457 If the command does not support the formatted nickname string
458 it will assume that the sent string is the actual nickname.
459 Affected file lib/silcclient/command.c.
461 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Added public key authentication support to OPER and SILCOPER
464 commands in the client library. Affected file is
465 lib/silcclient/command.c.
467 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Changed the get_auth_methdod client operation to be asynchronous.
470 It can be async if the application resolves the authentication
471 method from the server during the negotiation. Added new
472 SilcGetAuthMeth completion callback that the application will
473 call after resolving the authentication method.
475 Added function silc_client_request_authentication_method that
476 the application can use to resolve the authentication method
477 from the server. Added also SilcConnectionAuthRequest callback
478 that the library will call after the server has replied. The
479 application can call this function if it does not know the
480 current authentication method.
482 Affected files are lib/silcclient/client.c and
483 lib/silcclient/silcapi.h.
485 * The Irssi SILC client now automatically resolves the authentication
486 method incase any configuration information is not present (and
487 currently there never is). The affected file is
488 irssi/src/silc/core/client_ops.c.
490 * Fixed public key authentication from the client library.
491 Affected file lib/silcclient/protocol.c. Changed also the
492 protocol specification about the public key authentication in
493 the connection authentication protocol. The actual data to be
494 signed is now computed with a hash function before signing.
496 * Fixed the public key authentication from the server as well.
497 Affected file silcd/protocol.c.
499 * Removed the mlock()'s from the memory allocation routines.
500 Affected file lib/silcutil/silcmemory.c. The ./configure does
501 not check anymore for the mlock(). Affected file is
504 * Fixed USERS command in server to allow the execution of the
505 command for private and secret channels if the client sending
506 the command is on the channel. Affected file silcd/command.c.
508 * Fixed silc_client_get_clients_local to return the clients
509 count correctly. It could return wrong value. Affected file
510 lib/silcclient/idlist.c.
512 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
514 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
515 types. The assembler optimizations seemed not to like 64-bit
516 data types. The assmebler optimizations thus are now enabled
517 also for BSD systems as opposed to only enable them for Linux.
519 * Do not check for threads at all on BSD systems. Affected
520 file configure.in.pre.
522 * Removed -n and -h options from the Irssi SILC Client since
523 they are not used in silc.
525 * Fixed the prime generation to assure that the first digit
526 of the generated random number is not zero since our conversion
527 routines does not like number strings that starts with zero
528 digit. If zero digit is seen the random number is regenerated.
529 This caused some corrupted RSA keys when the zero first digit
530 was met. Affected file lib/silcmath/silcprimegen.c.
532 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
534 * Fixed WIN32 configuration in the ./configure script.
535 Fixed to include xti.h on environments that has it.
536 Patches by Carsten Ilchmann and andrew.
538 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
540 * Changed the silc_id_create_client_id to be collision
541 resistant. It is now assured that there cannot be created
542 two same client ID's. I suspect that some weird bugs in
543 the server were actually caused by duplicate Client IDs.
544 Affected file silcd/serverid.[ch]. A router receiving
545 new ID now also assures and informs the sending server
546 if the ID caused collision.
548 * Changed the silc_id_create_channel_id to also assure that
549 there are no collisions.
551 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
553 * Statement about ignoring the Mutual Authentication flag when
554 performing rekey with PFS was a bit misleading. It is ignored
555 if it was set in the initial negotiation, it cannot be even
556 set in the rekey. Fixed in the ke-auth draft. Started the
557 new versions of the protocol drafts in the doc/.
559 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Fixed a bug in silc_client_command_identify_save when saving
562 new channel information. The channel name was no duplicated
563 and caused crash on exit. Affected file is
564 lib/silcclient/command_reply.c.
566 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Fixed the getkey command handling in the server. Send just
569 empty OK reply to the sender if the key could not be fetched
570 (but everything else was ok, like the key just was not available).
571 Changed the public key parameter to optional in the protocol
572 specs so that empty OK reply can be sent. Affected file
575 Added a message to Irssi SILC client to tell to user if the
576 server did not return a public key.
578 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
580 * Fixed a channel key regeneration bug. It registered new
581 timeout tasks exponentially until all system resources were
582 used. Affected file silcd/server.c.
584 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Added the SILC Document generator to the scripts/silcdoc.
587 It can be used to generate the Toolkit Reference Manual out
588 of the source tree. Internally it will also use the RoboDoc
589 generator now imported in util/robodoc.
591 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
593 * Added couple of return's in rekey protocol if error orccurred
594 during the protocol. The execution must be terminated.
595 Affected file silcd/protocol.c. Also, terminate the protocol
598 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
600 * The client's Client ID was created initally from the wrong
601 nickname (it could have been in format nick@host) in the
602 silc_server_new_client. Affected file silcd/packet_receive.c
604 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Added some SILC_LOG_ERROR's to various error conditions
607 if client could not be added to ID cache. Affected files
608 silcd/packet_receive.c and silcd/server.c.
610 * When client's sock->user_data is freed, NULL also the
611 client->router and client->connection pointers. Added check
612 for these pointers being NULL to various places around the
613 code. Affected file silcd/server.c.
615 * Added client->data.registered == TRUE checks to various
616 places around the code to assure that unregistered client's
617 are not handled when it is not allowed. Affected file
620 * Added `bool registered' fields to all
621 silc_idlist_[server|client]_get_* routines to indicate whether
622 the fetched client needs to be registered or not. Affected
623 file silcd/idlist.[ch].
625 * Add your own entry as registered to the ID cache in the
626 server. Affected file server.c.
628 * Fixed a bug in silc_server_new_server. The SilcServer was
629 set as the new server's context instead of SilcServerEntry.
630 This naturally caused some weird bugs.
632 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Do not delete the channel rekey task when adding it
635 for in silc_server_create_channel_key.
637 * Changed the silc_server_create_channel_key to return
638 TRUE or FALSE to indicate the success of the channel key
641 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Fixed MSVC++ project files and added missing files to
644 Makefiles under win32/.
646 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
648 * Do not add TCP_NODELAY flag if the operating system
649 does not have it defined. Affected files are
650 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
652 * Fixed buffer overflow from Irssi SILC Client. Affected
653 file irssi/src/fe-common/core/themes.c.
655 * Fixed double free in client library in the file
656 lib/silcclient/client.c when disconnecting from server.
658 * Applied double free patch from cras to Irssi SILC client.
659 Affected files irssi/src/core/[modules/expandos].c
661 * Fixed the disconnection handling to Irssi SILC Client.
662 The application must call silc_client_close_connection
663 in ops->connect client operation in case of failure of
664 the connection. Affected file is
665 irssi/src/silc/core/client_ops.c.
667 * Do not set sock->protocol to NULL in the function
668 silc_client_close_connection after executing the protocol's
669 final callback since the sock might not be valid anymore.
670 Affected file lib/silcclient/client.c.
672 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Do not enable SILC_THREADS if the linking with libpthread
675 did not happen. Affected file configure.in.pre.
677 * Added notion to protocol specification that server must
678 verify the sent authentication payload with CMODE when
679 setting the channel founder key. Implemented it to the
680 server. Affected file silcd/command.c.
682 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Added _EXTRA_DIST SILC distribution variable to the
685 distributions file. It is used to conditionally add extra
686 files or directories to the specific distribution. Affected
687 files ./prepare, Makefile.am.pre and distributions.
689 Removed the `_' from the start of the distribution names.
692 * Added README.WIN32 for instructions to compile the Toolkit
695 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Fixed a double free in disconnection in the server. Affected
698 file is silcd/server.c.
700 * Fixed the lib/silcske/groups.c to work now also with GMP
701 MP library. The string conversion did not work when using
702 specific base and the base is indicated in the string as well.
704 * Created win32/ directory which now includes MSVC++ specific
705 stuff so that toolkit (DLLs) may be compiled with MSVC++.
706 It will appear only in the toolkit distribution
708 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Changed the key material distribution function in case when
711 the hash output is too short. The data is now concatenated
712 a bit differently than it used to. Made the change to the
713 SKE protocol specification.
715 * Added better GMP detection to configure.in.pre. A patch
718 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Fixed a minor bug in SKE that might cause some problem on
721 some platforms. Affected file lib/silcske/silcske.c.
723 * Added the cookie checking for initiator in the SKE. It checks
724 that the responder returns the sent cookie unmodified. The
725 affected file is lib/silcske/silcske.c. Added new SKE
726 error type INVALID_COOKIE that can be sent during the
727 negotiation. Fixed some memory leaks as well.
729 * Added the "invalid cookie" error message to Irssi SILC client's
732 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
734 * Added `task_max' field to the SilcClientParams to indicate
735 the maximum tasks the scheduler can handle. If set to zero,
736 default values are used. Affected file lib/silcclient/silcapi.h.
738 * Fixed memory leaks in silc_client_close_connection. Affected
739 file lib/silcclient/client.c.
741 * Added silc_client_del_client_entry to client library to free
742 all memory of given client entry. Affected file is
743 lib/silcclient/idlist.[ch].
745 * Added new functions silc_client_del_channel and
746 silc_client_del_server to delete channel and server entries.
747 Affected file lib/silcclient/[silcapi.h/idlist.c].
749 * Removed silc_client_del_client_by_id from silcapi.h.
751 * Fixed the INFO command to return the server's own info
752 correctly when querying by Server ID. Affected file is
755 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Removed the non-blocking settings in WIN32 code in the
758 silc_sock_[read/write] and added SleepEx instead. Affected
759 file lib/silcutil/win32/silcwin32sockconn.c. The availability
760 of input data is now checked with FIONREAD and ioctlsocket.
762 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
764 * Call silc_schedule_task_del_by_context in the
765 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
766 Affected file lib/silccore/silcprotocol.c.
768 * Call silc_protocol_cancel for active protocols in the
769 silc_server_close_connection if the funtion
770 silc_server_free_sock_user_data has not been called.
771 Affected file silcd/server.c.
773 * Generic tasks cannot be deleted using the del_by_fd
774 task deleting function since generic tasks does not match
775 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
777 * Added a notion to SILCOPER help file that the SILCOPER works
778 only on router server, not on normal server.
780 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Added for WIN32 support for the new scheduler as well.
783 Affected file lib/silcutil/win32/silcwin32schedule.c.
785 * Fixed the SHA1 implementation to work on various platforms.
787 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
790 API. It is part of the scheduler now. Everything else is
791 as previously but some functions has changed their names.
792 Checkout the lib/silcutil/silcschedule.h for the interface.
793 Updated all applications to use the new interface. Affected
794 files are lib/silcutil/silcschedule.[ch].
796 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Found a bug in the SKE implementation. The HASH value,
799 specified by the protocol, was not computed correctly. The
800 public key of the responder was not added to the computation
801 even though it is mandatory. Affected file lib/silcske/silcske.c.
802 This unfortunately causes incompatibilities with older
805 * Added WIN32 specific network init and uninit functions:
806 silc_net_win32_init and silc_net_win32_uninit to init and uninit
807 the Winsock2. Affected file lib/silcutil/silcnet.h and
808 lib/silcutil/win32/silcwin32net.c.
810 * Set the socket always to nonblocking mode on WIN32 after
811 reading data or writing data. Affected file is
812 lib/silcutil/win32/silcwin32sockconn.c.
814 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Fixed various compilation problems under WIN32. Affected
817 files lib/silcutil/win32/silcwin32thread.c and
818 lib/silcutil/win32/silcwin32schedule.c.
820 * Removed all _internal.h #includes from public header
821 files. Internal headers must never be included from
824 Removed also the lib/silcske/payload_internal.h file.
826 * All include files that may be needed (public and some others
827 included by the public headers) by application developers are
828 now copied to the ./includes directory. It does not copy any
829 internal headers. Affected file Makefile.defines.pre and all
830 Makefile.am's under lib/ and subdirs.
832 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Do not change the ~/.silc directory's permissions automatically.
835 Affected file irssi/src/silc/core/clientutil.c.
837 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Do not cancel the protocol in silc_server_close_connection
840 it might cause recursion. Now cancelled in the function
841 silc_server_free_sock_user_data. Affected file silcd/server.c.
843 * Fixed the silc_server_remove_clients_by_server to regenerate
844 the channel keys correctly finally. Added also new function
845 silc_server_remove_clients_channels to actually do it.
846 Affected file silcd/server.c.
848 * Fixed the silc_server_new_channel to not crash by giving
849 wrong router to the new channel. Affected file is
850 silcd/packet_receive.c.
852 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
854 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
855 which is given as argument to the silc_client_alloc now.
856 It can be used to configure the client and set various parameters
857 that affect the function of the client.
859 * The USERS command in server did not check whether the channel
860 is private or secret. Affected file silcd/command.c.
862 * Added new argument to the USERS command in protocol specification.
863 The USERS command now can take the channel name as argument
864 as well. Added support for this in client and server and
865 updated the protocol specs.
867 * Completed the GETKEY command in client. It can be now used
868 to fetch also servers public key not only some clients.
869 Affected files lib/silcclient/command[_reply].c.
871 * Added silc_client_get_server to return server entry by the
872 server name. Affected files lib/silcclient/silcapi.h and
875 * Redefined the IDENTIFY command in protocol specification to be
876 more generic. It now can be used to query information about
877 any entity in the SILC Network, including clients, servers and
878 channels. The query may be based either the entity's name
879 or the ID. Added support for this in both client and server.
881 Affected files silcd/command.c and lib/silcclient/command.c
884 * Optimized the WHOIS and WHOWAS commands in the server. Removed
885 the _from_client and _from_server functions. Affected file
888 * Added silc_client_get_channel_by_id_resolve to the file
889 lib/silcclient/silcapi.h to resolve channel information by
890 its ID. Added also silc_client_get_channel_by_id that
891 does not resolve it from the server.
893 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
895 * Added SilcServerEntry context into the client library
896 to represent one server. The INFO command now allocates
897 these to save the resolved server info. For now on the
898 client library will also keep information about servers,
899 connected and resolved with INFO.
901 The INFO command now allocates the SilcServerEntry context
902 and saves the server info there. The COMMAND_REPLY in
903 the INFO now returns the parameters to application in
904 same order as defined in the protocol specification.
906 The entries are cached in the client->server_cache.
908 * The INFO command is now issued after received the Client ID
909 from the server. Affected file lib/silcclient/client.c.
911 * The CMODE_CHANGE notify may now return also an SilcServerEntry
912 to the application as the mode changer might be server.
913 It is guaranteed that NULL is not returned anymore to the
914 application. Affected file lib/silcclient/client_notify.c.
916 The ID Type is now also passed to the application so that
917 it can check whether the returned entry is SilcClientEntry
920 Added new function silc_client_get_server_by_id to return
921 the server entry by ID. Affected files are the
922 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
924 * Do not create the channel in the Irssi SILC Client when issuing
925 the JOIN command but when received the sucessful JOIN command
926 reply. Otherwise the channel might get created even though we
927 could not join it. The Affected file is
928 irssi/src/silc/core/[silc-channels.c/client_ops.c].
930 * Fixed a channel joining bug in router. The router must also
931 check the channel modes, invite and ban lists etc. when serving
932 the JOIN command sent by normal server. Affected file is
933 silcd/command.c. The router now resolves the client's
934 information from the server who sent the JOIN command if it
935 does not know it, and processes the JOIN command only after
938 * Changed the SilcCommandCb to take new argument; void *context2.
939 Affected file lib/silccore/silccommand.h
941 The second argument in the command callbacks in the server now
942 includes the SilcServerCommandReplyContext if the command was
943 called as pending command callback from the command reply.
944 Otherwise it is NULL. When called as pending the status of the
945 command reply will be checked and if it was erronous the
946 error will be sent to the original sender of the command.
947 This way the client always receives the error messages even
948 though the server was actually the one who received the error
949 when it resent the command to router, for example. Affected
950 files silcd/command[_reply].[ch].
952 * Fixed sending WHOWAS command's error message to client if
953 the requested client could not be found. It was missing.
956 * Changed the CMODE and CUMODE commands reply arguments in the
957 protocol specification. The Channel ID is now sent in both
958 of the commands to identify the channel. Implemented this
959 new feature to the client and server. Affected files
960 lib/silcclient/command_reply.c and silcd/command.c.
962 * Made better checks for invite and ban lists in the JOIN
963 command in server. Affected file silcd/command.c.
965 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
967 * The server now performs the incoming host IP/DNS lookup
968 using the silc_socket_host_lookup and thus does not block
969 the server anymore. Affected file silcd/server.c.
971 * Completed the multi-thread support for SILC Scheduler in
972 the lib/silcutil/silcschedule.c.
974 * Fixed the configure.in.pre to detect the pthread correctly
977 * Fixed a deadlock in silc_task_queue_wakeup in the file
978 lib/silcutil/silctask.c.
980 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Added new function silc_schedule_wakeup that is used in
983 multi-threaded environment to wakeup the main thread's
984 schduler. It needs to be used when a thread adds a new task
985 or removes a task from task queues. After waking up, the
986 scheduler will detect the task queue changes. If threads
987 support is not compiled in this function has no effect.
988 Implemented the wakeup mechanism to both Unix and WIN32
989 systems. Affected files are lib/silcutil/silcschedule.[ch],
990 lib/silcutil/unix/silcunixschedule.c and the
991 lib/silcutil/win32/silcwin32schedule.c.
993 * Added new function silc_task_queue_wakeup to wakeup the
994 scheduler by the specified task queue. Affected file
995 lib/silcutil/silctask.[ch].
997 * The silc_socket_host_lookup_start now wakes up the scheduler
998 after adding the timeout task. Affected file is
999 lib/silcutil/silcsockconn.c.
1001 * The silc_socket_host_lookup is synchronous now if the threads
1002 support is not compiled in. However, the callback is still
1003 called asyncronously through the scheduler, anyway. Affected
1004 file lib/silcutil/silcsockconn.c.
1006 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Added new function silc_socket_host_lookup to perform
1009 asynchronous IP and FQDN lookups for the socket connection.
1010 Affected files lib/silcutil/silcsockconn.[ch].
1012 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1015 that may or may not compile the mutex support in.
1017 Changed the silc_mutex_alloc interface. It allocates the
1018 mutex now to the sent pointer and returns TRUE or FALSE.
1020 Affected file lib/silcutil/silcmutex.h.
1022 * Wrote the SILC Task Queue interface to support multi-threads.
1023 Affected file lib/silcutil/silctask.[ch].
1025 * Wrote the SILC Scheduler to support multi-threads. Affected
1026 file lib/silcutil/silcschedule.c.
1028 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1031 in lib/silcutil/win32/.
1033 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * Defined SILC Mutex API and SILC Thread API and implemented
1036 them for Unix. Affected files are
1037 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1038 lib/silcutil/unix/silcunixmutex.c and
1039 lib/silcutil/unix/silcunixthread.c.
1041 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Fixed the silc_server_remove_clients_by_server's channel
1044 key re-generation. The hash table handling was incorrect
1045 and would not work with many channels. Affected file is
1048 * Fixed some memory leaks around the server code.
1050 * Rewrote the silc_server_get_users_on_channel to support IPv6
1051 based Client ID's. Affected file silcd/server.c.
1053 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1054 specification. However, a separate document must be written
1055 to define the detailed signing procedure and the payload
1056 associated with the flag. Defined the flag to the
1057 lib/silccore/silcchannel.h as well.
1059 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Changed the dynamic tables to static size tables in the
1062 lib/silccrypt/silchmac.c.
1064 * Removed GCC dependencies from the code. A patch by cras.
1066 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1068 * Do not show the error "Error receiving packet bla bla"
1069 in server if it really was not an error (-2 means that reading
1070 is pending). Affected file silcd/server.c.
1072 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Fixed a possible crash in silc_server_remove_clients_by_server
1075 in silcd/server.c. Fixed there also some memory leaks.
1077 * Fixed the silc_idlist_replace_client_id. It could replace
1078 wrong key in the hash table. Affected file silcd/idlist.c.
1080 * Do not check whether there are global users on the channel
1081 if the channel->global_users is FALSE. Affected functions
1082 silc_server_remove_from_one_channel and
1083 silc_server_remove_from_channels in silcd/server.c. Also,
1084 do not check if the removed client is local as we can be
1085 sure that global client was not removed from the channel
1086 and checking for global users is not needed.
1088 * The silc_server_remove_clients_by_server now re-generates
1089 the channel keys correctly for those channels that had
1090 clients removed from them. Affected file silcd/server.c.
1092 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Found the reason of random crashes in the server. We weren't
1095 ignoring the SIGPIPE signal (which can be sent in write())
1096 and it crashed the server. Affected file silcd/silcd.c.
1098 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Assure that sock->user_data is not NULL in the function
1101 silc_server_packet_send in silcd/packet_send.c.
1103 * Disconnect the remote connection if it could not be added
1104 to any ID lists in the server. The affected file is
1107 * Check in silc_server_packet_send[_real/dest] that the
1108 socket is not disconnecting and ignore the data if it is.
1109 Affected file silcd/packet_send.c.
1111 * Define inline to __inline on native WIN32 compilation.
1112 Affected file includes/silcwin32.h.
1114 * Added some explicit type casts for inline code since MSVC
1115 require them. Affected files lib/silcutil/silcbuffer.h,
1116 lib/trq/silcdlist.h and lib/trq/silclist.h.
1118 * Print warning in log files from now on if the packet
1119 decryption fails. Affected file silcd/server.c.
1121 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Changed the `say' client operation's interface to accept
1124 new `type' argument to indicate the type of the message sent
1125 by the library. The application may filter the library's
1126 messages according the type. The affected file is the
1127 lib/silcclient/silcapi.h.
1129 * Added two new functions to lib/silcclient/silcapi.h:
1130 silc_client_del_client and silc_client_del_client_by_id.
1131 Affected file lib/silcclient/idlist.c.
1133 * Moved the clientincludes.h from includes/ to silc/ and
1134 serverincludes.h from includes/ to silcd/.
1136 * The modes for the CMODE and CUMODE are now passed as
1137 uint32 for application with COMMAND_REPLY. The affected
1138 file is lib/silcclient/command_reply.c.
1140 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * /WHOIS without arguments shows client's own information.
1143 Affected file lib/silcclient/command.c.
1145 * Changed PING to not accept any arguments. The specs
1146 says that client can ping only the connected server so
1147 requiring an argument is not needed. Affected file is
1148 lib/silcclient/command.c.
1150 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Fixed a fatal bug in private message sending and reception
1153 encryption and decryption when using private message keys.
1154 The implementation was incorrect and did not follow the
1155 specification. It causd that some of the message were
1156 lost since it did not use the sending and receiving keys
1157 as the protocol suggests. This has been fixed and will cause
1158 incompatibilities with older clients when sending private
1159 message encrypted with private message keys. Affected files
1160 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1161 and various other in Irssi SILC Client.
1163 Added `responder' boolean argument to the functions
1164 silc_client_add_private_message_key[_ske] to indicate when
1165 the key is added as responder or initiator of the key
1168 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1170 * Removed the silc_ske_check_version function and created
1171 a SilcSKECheckVersion callback. Added also a function
1172 silc_ske_set_callbacks that is now used to set all SKE
1173 callbacks. The callback functions are not given to
1174 the SKE functions anymore, but this function is used to
1177 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1179 * Added `silc_version' argument to the silc_client_alloc
1180 to define the version of the application for the library.
1181 The library will use the version string to compare it
1182 against the remote host's (usually a server) version
1183 string. Affected file lib/silcclient/silcapi.h
1185 * Added the KE protocol context to Key Agreement context
1186 in client library so that we can abort the SKE if it
1187 is in process when we get timeout. Affected file is
1188 lib/silcclient/client_keyagr.c.
1190 * Do not resolve the client ID forever if it returns in the
1191 first time that such client does not exist. This was done
1192 for example with private message. Affected file is
1193 lib/silcclient/client_prvmsg.c.
1195 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Do not add regex.h for WIN32. The affected file
1198 includes/silcincludes.h.
1200 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1201 not work yet 100%. It generates the DLL's automatically
1202 when compiling with --with-win32 under cygwin.
1204 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * lib/contrib/regex.c is not compiled on WIN32.
1208 * Added silc_net_get_socket_opt function to the
1209 lib/silcutil/silcnet.h.
1211 * Added includes/silcwin32.h for WIN32 specific includes
1214 * Do not use ptime structure or any of the posix process
1215 functions on WIN32 in lib/silccrypt/silrng.c.
1217 * Added silc_gettimeofday to provide generic function
1218 for struct timeval on all platforms. Added the function
1219 to lib/silcutil/silcutil.h.
1221 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1224 library as they clearly belong there. As a plus side we
1225 can make the actual socket connection routines platform
1228 Added also new generic function silc_socket_read and
1229 silc_socket_write (that used to be silc_packet_[read/write].
1230 The implementation of these are platform specific.
1232 * Added WIN32 specific routines of silc_socket_[read/write]
1233 to lib/silcutil/win32/silcwin32sockconn.c.
1235 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Added preliminary support for native WIN32 compilation under
1238 cygwin (using the -mno-cygwin option for GCC) to the
1239 ./configure.in.pre. The --with-win32 now prepares the
1240 compilation for native WIN32.
1242 * Rewrote the SILC Scheduler interface in the file
1243 lib/silcutil/silcschedule.h. The scheduler is now context
1244 based and does not have anymore any global static scheduler.
1245 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1246 and created lib/silcutil/win32 directory for WIN32 based
1249 * Added Unix specific network routines to the
1250 lib/silcutil/unix/silcunixnet.c and the old
1251 lib/silcutil/silcnet.c includes now only generic routines.
1253 Added WIN32 specific network routines to the
1254 lib/silcutil/win32/silcwin32net.c.
1256 * Added Unix specific utility functions from the
1257 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1259 * Added WIN32 SILC Scheduler to the file
1260 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1263 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Do not handle JOIN notify in the server if the target client
1266 is not registered (idata->registered == FALSE). The affected
1267 file is silcd/packet_receive.c.
1269 * Update the nickrec->founder in event_cumode in the Irssi SILC
1270 client. Affected file irssi/src/silc/core/silc-channels.c.
1272 * Fixed the CUMODE_CHANGE notify handling in the server when
1273 server and router are announcing their clients on channels.
1274 Now the mode changes are saved and notified correctly. The
1275 affected file is /silcd/packet_receive.c.
1277 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1278 They really did not replace the cache entry in the ID Cache.
1279 Now they do that. Affected file silcd/idlist.c.
1281 * Fixed the KICK notify handling in the Irssi SILC client to
1282 update the channel records so that the kicked client does not
1283 appear to be on the channel. The affected file is
1284 irssi/src/silc/core/silc-channels.c.
1286 * Always update the conn->current_channel when executing command
1287 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1289 * Fixed the KILL notify handling in Irssi SILC client to remove
1290 the killed client on all channels.
1292 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Fixed the silc_parse_command_line to remove extra spaces
1295 from the start and end of the arguments. Affected file is
1296 lib/silcutil/silcutil.c.
1298 * Cancel and free any active protocol in the function
1299 silc_server_close_connection. Affected file silcd/server.c.
1301 * Cancel and free any active protocol in the function
1302 silc_client_close_connction. Affected file is
1303 lib/silcclient/client.c.
1305 * Do not execute the KILL command for clients that are in
1306 history (ie. they are not in the network). Affected file is
1309 * Fixed KILL notify handling, client does not crash anymore.
1310 Affected file irssi/src/silc/core/silc-channels.c.
1312 * Reduced the default packet buffer size from 2048 to 1024 in
1313 lib/silccore/silcpacket.c.
1315 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1316 counter to the SKE context that is incresed when the SKE library
1317 performs async operation outside the library. If the outside
1318 process frees the SKE context and FREED status will be set
1319 and the library will detect after the sync operation that the
1320 libary is freed. The affected files are
1321 lib/silcske/silcske[_status].[ch].
1323 * Resolve the client entry information in the function
1324 silc_client_channel_message to assure that NULL pointer is not
1325 passed as client entry to the application. */
1327 * Fixed the task timeout calculation to assure that there is
1328 never negative timeouts. The affected file is
1329 lib/silcutil/silcschedule.c.
1331 * Fixed the channel user mode notification sending in server.
1332 It was sent point-to-point to the router (or to server by router)
1333 but it needs to be destined to a channel. The routines now
1334 supports sending the channel user mode notifys to the channels
1335 when announcing clients and channels. Affected files are
1336 silcd/server.c and silcd/packet_receive.c.
1338 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1339 It did not actually replace the old channel entry in the cache.
1340 Affected file lib/silcclient/client_notify.c.
1342 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Fixed a possible crash in silc_packet_send_prepare. It now
1345 assures always that there is enough space in the buffer and
1346 at the tail area of the buffer (for MAC).
1348 Fixed the inbound buffer reallocation in silc_packet_read.
1349 It was old code and did not handle the reallocation correctly.
1352 The affected file is lib/silccore/silcpacket.c.
1354 * Fixed buffer overflow in silc_parse_nickname in the file
1355 lib/silcutil/silcutil.c.
1357 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * make install generates new server keys only if there is not
1362 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1365 Added check that if the NOREPLY is set then we will not send
1366 the away message. This avoids infinite loop of away messages
1367 if both clients are away. The affected file is
1368 lib/silcclient/client_prvmsg.c.
1370 * Fixed client crash if /NICK was given without arguments.
1371 Affected file lib/silcclient/command.c.
1373 * Server does not send the invite list in INVITE command back
1374 to the client if the list was not altered. Added this notion
1375 to the protocol spec as well. Affected file silcd/command.c.
1377 Fixed possible crash in INVITE command by checking the
1378 value of silc_server_get_client_route command.
1380 * Fixed the INVITE notify type handling. The arguments are now
1381 taken in correct order and client does not crash. The affected
1382 file is irssi/src/silc/core/silc-channels.c.
1384 Removed the "Inviting xxx to channel" message from the
1385 client library away and let the application handle it.
1386 Affected file lib/silcclient/command.c. Added that message
1387 to Irssi SILC client's message formats.
1389 * Fixed CMODE command crash in client. It now checks the
1390 amount of arguments correctly and does not crash. The affected
1391 file is lib/silcclient/command.c.
1393 * Do not create new channel automatically in silc_channels_join
1394 but check whether the channel by that name already exists.
1395 Affected file irssi/silc/core/silc-channels.c.
1397 * Do not send the SERVER_SIGNOFF to router if the disconnected
1398 entity was the router. Affected file silcd/server.c.
1400 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1401 SILC client as it was missing from there.
1403 Added the handling of the KICK notify to the Irssi SILC client
1404 as it was missing. Added "you have been kicked" message to
1405 Irssi SILC client's message modules formats.
1407 Added the handing of the KILL notify to the Irssi SILC client
1408 as it was missing. Added the kill message module formats
1411 The affected file is irssi/src/silc/core/silc-channels.c.
1413 * The router did not save the channel mode the server announced.
1414 Affected file silcd/packet_receive.c.
1416 * Fixed a possible crash in INFO command in server. If the
1417 server did not provide the server info it crashed. Affected
1418 file silcd/command.c.
1420 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Fixed the GETKEY command in the server to check also the
1423 global list. Otherwise the GETKEY would not work correctly
1424 in normal SILC server. Affected file silcd/command.c.
1426 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Fixed GETKEY crash, it crashed if the command did not succseed.
1430 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1432 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1433 is now real and not just an macro interface to GMP.
1435 Removed the entire GMP from the source tree and imported new
1436 NSS MPI library instead. Reason for removing GMP is that it is
1437 extremely large and compiles extremely slow. The NSS MPI
1438 is only a few files and compiles in less than 10 seconds.
1439 The speed is also about the same as GMP. The MPI is imported
1440 to lib/silcmath/mpi.
1442 If the system has GMP installed we will still use the GMP.
1443 If it is not then the NSS MPI will be compiled.
1445 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Merged a long nickname (127 characters long) crash bugfix from
1448 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1450 * Merged a freed memory reference bugfix from Irssi CVS tree.
1451 Affected file irssi/src/core/commands.c.
1453 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Added the server's public key sving and verification to the
1456 server when performing the SKE. This was missing and the
1457 remote server's (or router's) public key was accepted without
1458 checking whether we have it previously or trust it at all.
1459 Affected file silcd/protocol.c.
1461 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Check in the silc_server_timeout_remote if protocol is active
1464 and make sure that the protocol's final callback is called so
1465 that all memory if freed. Affected file silcd/server.c.
1467 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * silc_server_whois_send_reply crashed the server if the nickname
1470 was 127 characters long. Affected file silcd/command.c.
1472 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Added sanity check to the silc_server_new_client. If the hostname
1475 is provided inside username then check that the provided hostname
1476 really is the same as the resolved one. If the hostname was not
1477 resolved then check it from the public key. Affected file is
1478 silcd/packet_receive.c.
1480 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1481 if the server disconnected us and the connection is not valid
1482 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1484 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1485 the library to the lib/silcutil/silcutil.[ch].
1487 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Close log file after open. Affected file
1490 lib/silcutil/silclog.c.
1492 * Check whether sock == NULL in silc_client_send_packet and return
1493 if it is. Affected file lib/silcclient/silcclient.c.
1495 * Check rec->entry == NULL in the Irssi SILC Client before
1496 sending the channel message. Affecte file is
1497 irssi/src/silc/core/silc-servers.c.
1499 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Merged a splitted window bugfix from Irssi CVS tree. The
1502 affected file is irssi/src/fe-text/textbuffer-view.c.
1504 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1505 It did not print nickname.
1507 * Improved the distributions system a bit.
1509 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1511 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1512 irssi/src/fe-text/gui-window.c.
1514 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1515 to in-active server. The affected file is
1516 irssi/src/silc/core/client_ops.c.
1518 * Resolve the client in USERS command reply if the entry does
1519 not have username resolved. The affected file is
1520 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1521 command to WHOIS command to really resolve stuff. The USERS
1522 is not used any more in any critical section so WHOIS can
1523 be used even though it might be slower than IDENTIFY.
1525 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1528 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Changed the protocol API a bit more consistent in the
1531 lib/silccore/silcprotocol.[ch].
1533 * Changed the following headers to ROBODoc format:
1535 lib/silccore/silcpayload.h
1536 lib/silccore/silcprotocol.h
1537 lib/silccore/silcsockconn.h
1539 All core library headers are now formatted.
1541 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Fixed a bug in Irssi SILC client; do not show that you are
1544 server/router operator if you really are not. Affected file is
1545 irssi/src/silc/core/client_ops.c.
1547 * Renamed silc_command_free_payload to silc_command_payload_free.
1548 Affected file lib/silccore/silccommand.h
1550 * Added silcmath.h to include the prototoypes of various routines
1551 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1554 * Changed the following headers to ROBODoc format:
1556 lib/silccore/silcchannel.h
1557 lib/silccore/silccommand.h
1558 lib/silccore/silcid.h
1559 lib/silccore/silcidcache.h
1560 lib/silccore/silcmode.h
1561 lib/silccore/silcnotify.h
1562 lib/silccore/silcpacket.h
1563 lib/silcmath/silcmath.h
1565 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Added checking to the server code not to start the server if
1568 ciphers and stuff are not configured properly. Affected files
1569 silcd/serverconfig.[h] and silcd/server.c.
1571 * Changed the layout of the header files of the public interfaces
1572 in the SILC libraries. The new layout supports ROBODoc
1573 documentation tool (and some others) so that it is easy to create
1574 a library reference manual. All the other headers and source
1575 code must still follow the CodingStyle document. Also source
1576 code must not include these ROBODoc stuffs, only the headers.
1577 Furthermore, all public interface headers must now be named
1578 by using `silc' prefix, example: silcapi.h, silccipher.h.
1579 Some files were renamed due to this. All the other headers
1580 must not be used as public interfaces. I will update the
1581 CodingStyle document later. Changed following headers, so far:
1583 lib/silcclient/silcapi.h
1584 lib/silccore/silcauth.h
1585 lib/silccore/silcprivate.h
1586 lib/silccrypt/silcdh.h
1588 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * Removed silc_client_packet_send_flush from the client library
1593 as it is not needed. Affected file lib/silcclient/client.[ch].
1595 * Added printing of message of unresolved authentication method
1596 to the Irssi SILC client. Added it to the module formats.
1597 Removed the same message from the client library.
1599 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Added new distribution feature, DISTLABEL. Every distribution
1602 can define own preprocessor label that can be used in the
1603 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1604 file distributions, acconfig.h.pre and prepare.
1606 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Added Makefile.defines_int to include the actual definitions
1609 for Makefile.defines.in. Tested the new distribution system,
1610 created distributions and tested installation.
1612 * Added AWAY message printing to the Irssi SILC client. Added
1613 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1615 * Added SCONNECT command to call the SILC's CONNECT command.
1616 Cannot use CONNECT directly since Irssi uses that internally.
1617 Affected file irssi/src/silc/core/silc-servers.c.
1619 Added ACTION local command. It is same as ME command but takes
1620 the channel as mandatory argument.
1622 Rewrote some of the Irssi's help files to suite for SILC
1625 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Added Makefile.defines[.in] that should for now on be included
1628 in all Makefile.am file in the source tree. That file includes
1629 all common compilation definitions for SILC source tree.
1631 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Minor changes to the ./prepare script to change the package
1634 name according the distribution name to the configure.in.
1636 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Created new distribution system. Added file `distributions'
1639 that defines all the distributions that can be created out of
1640 the SILC source tree. The ./prepare script now reads that
1641 file to determine how to prepare the distributions. The
1642 first argument to the ./prepare is the name of the distribution
1643 and second is the version of the distribution. If given
1644 without arguments it creates the default (toolkit) distribution
1645 with the default version (defined in ./prepare).
1647 All Makefile.am files that are subject to the distributions
1648 are now named as Makefile.am.pre. These are ./Makefile.am
1649 and lib/Makefile.am. Others may be changed later.
1651 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Added invite list, ban list, some key management and connection
1654 error message printing to module formats in the Irssi SILC client.
1656 * Added new silc_client_set_away_message to set the away message
1657 that is back to the person who sent private message. The
1658 affected file lib/silcclient/silcapi.h and the
1659 lib/silcclient/client_prvmsg.c.
1661 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Fixed the private message sending in the Irssi SILC client,
1664 added local command KEY to the Irssi SILC client.
1666 Added key management and key agreement message formats to the
1667 irssi/src/fe-common/silc/module-formats.[ch].
1669 Added USERS (alias WHO) printing, server/router operator
1670 indication and LIST command printing to the module formats.
1672 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1674 * Fixed channel joining notify handling, cumode notify handling
1675 from Irssi SILC client.
1677 * Added SILC specific module-formats to the Irssi SILC client so
1678 that SILC specific message hilighting, colors etc is possible.
1679 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1681 Added channel mode, channel user mode, actions, notices,
1682 whois and whowas printing to the the module-formats.c.
1684 * Fixed a bug in channel deletion in the server. The channel
1685 is not left to the cache even if the channel founder auth mode
1686 is set when there are no users anymore on the channel. Affected
1687 file silcd/server.c.
1689 * The silc_net_localhost now resolves the entire hostname including
1690 the domain name. Affected file lib/silcutil/silcnet.c.
1692 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Changed the ask_passphrase client operation to be ascynchronous.
1695 It has now a completion callback and a context that the
1696 application must call after it has got the passphrase from
1697 the user. Affected files lib/silcclient/silcapi.h,
1698 lib/silcclient/protocol.c, lib/silcclient/command.c and
1701 Added SilcAskPassphrase callback that the application calls
1702 to deliver the passphrase to the library.
1704 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1705 The public key verification and especially a certificate
1706 verification is asynchronous procedure.
1708 Added new SILC_SKE_STATUS_PENDING status to indicate the
1709 request is pending and a callback will be called to finalize
1712 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1713 indicate that remote end did not send its public key (or
1714 certificate), even though we require it. Added check for this
1715 condition in the SKE. This was a security bug, now fixed.
1717 Defined new SilcSKEVerifyCbCompletion callback that is called
1718 when the verification process is completed.
1720 The affected files lib/silcske/silcske_status.h and
1721 lib/silcske/silcske.[ch].
1723 * Changed the verify_public_key client operation to be async
1724 as well. Defined SilcVerifyPublicKey callback that is used to
1725 indicate the success of the public key verification process.
1727 Changed the server and client to use the new async client
1730 * Changed the Irssi SILC client's internal scheduler to be called
1731 twice as many times as it used to be. As a result the client
1732 should be a bit faster now. Affected file is
1733 irssi/src/silc/core/silc-core.c.
1735 * Added support to Irssi SILC client of asynchronous public key
1736 verification and passphrase inquiry. Affected file is
1737 irssi/src/silc/core/silc-core.c.
1739 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Do not say "You have left channel %s" in client library.
1742 Moved it to the application. Affected files are
1743 lib/silcclient/command.c and silc/client_ops.c.
1745 * Fixed silc_client_get_clients. Command context was not
1746 duplicated and was freed memory in the callback. Affected
1747 file lib/silcclient/idlist.c.
1749 * Do not say "you are now talking..." on JOIN command in the
1750 client library. The appliation must handle it.
1752 * Do not say ".. changed topic to" in command reply in the
1753 client libary. The application must handle it.
1755 * Fixed TOPIC command sending in the client library.
1757 * Fixed a memory leak in silc_client_command_free in the file
1758 lib/silcclient/command.c.
1760 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Imported a modified version of Irssi client to the source tree.
1763 The Irssi will be used to create a new client called
1764 Irssi SILC. Imported to irssi/.
1766 Added silc_core_init_finish function to the Irssi. Affected
1767 file irssi/configure.in.
1769 A lot changes in the Makefile.ams around the irssi tree.
1771 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * Do not rehash if the new size is same as the old size of the
1774 hash table, in the silc_hash_table_rehash*. The affected file
1775 lib/silcutil/silchashtable.c.
1777 * Replaced hash_table_del_by_context calls from the server
1778 (when channel->user_list and client->channels) to the
1779 hash_table_del as it is sufficient and faster.
1781 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1783 * Added silc_hash_table_list, silc_hash_table_get and the
1784 SilcHashTableList structure to provide an alternative way to
1785 traverse the hash table. The affected files are
1786 lib/silcutil/silchashtable.[ch].
1788 * Changed the server's idlist routines to use the hash table
1789 routines to optimize the code.
1791 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Replaced the client entry's `channel' list and channel entry's
1794 `user_list' list to hash tables for optimized lookup. Changed
1795 the code to use the hash table interface around the code.
1796 Affected file lib/silcd/idlist.[ch].
1798 * Added `auto_rehash' boolean argument to the function
1799 silc_hash_table_alloc to indicate whether the hash table should
1800 auto-rehash when it thinks is appropriate time. It will
1801 increase the hash table size if the there is twice as much
1802 entries in the table than the size of the table, and will
1803 decrease the size if there are twice as less entries than
1804 the size of the table.
1806 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1810 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * silc_idcache_purge_by_context deletes the entry now by context
1813 as it is supposed to do. Affected file lib/silccore/idcache.c.
1815 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1816 client is not anymore valid (WHOWAS givens the info) and not
1817 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1819 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Removed the `data' and `data_len' arguments from the ID Cache
1822 interfaces and added `name' argument. ID Cache does not handle
1823 anymore the binary data only a names associated with given ID.
1825 * When hashing a Client ID with silc_hash_id the entire ID is
1826 not hashed anymore, instead only the hash of the Client ID is
1827 hashed. This way we can access the Client ID from the cache
1828 with Client ID but with the hash of the ID (which is a hash of
1829 the nickname) as well without any difference in performance.
1831 Added also silc_idcache_find_by_id_one_ext to do one on one
1832 searching when we have the actual ID. Added also function
1833 silc_hash_client_id_compare. The affected files are
1834 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1836 * When hashing the name associated with a ID it is always done
1837 in lowercase. This way we can access the cache without worrying
1838 about case-sensitivity, even though, for example nicknames are
1841 * Fixed a bug in server with channel message sending. It put
1842 wrong ID type as destination ID. The affected file
1843 silcd/packet_send.c.
1845 * silc_idcache_del_by_context now deletes from all hash tables
1846 by context. Affected file lib/silccore/idcache.c.
1848 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Changed the client library to use the new ID Cache interface.
1851 Changes around the source tree.
1853 * Added silc_hash_table_rehash_ext to rehash with specific
1854 hash function. Affected file lib/silcutil/silchashtable.[ch].
1856 * Added silc_hash_string_compare to compare two strings in the
1857 hash table. Affected file lib/silcutil/silcutil.[ch].
1859 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Added new function silc_idcache_del_by_context into the
1862 lib/silccore/idcache.[ch].
1864 * Changed the server's ID list routines to use the new ID Cache
1865 interface. Changes around the source tree.
1867 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Added silc_hash_table_del[_by_context]_ext functions in to the
1870 lib/silcutil/silchashtable.[ch].
1872 Removed silc_hash_table_find_all* routines and added new
1873 silc_hash_table_find_foreach to replace them.
1875 Added silc_hash_table_replace_ext function as extended
1876 replacing function. Separated the simple hash table interface
1877 from the extended hash table interface in the file
1878 lib/silcutil/silchashtable.h.
1880 * Fixed minor bugs and changed it to use some of the new
1881 hash table functions in lib/silccore/idcache.c
1883 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Added new function silc_hash_table_find_all to return all keys
1886 in the hash table by the specified key. As the hash table is
1887 collision resistant it also makes it possible to have several
1888 duplicate keys in the hash table. This function may be used to
1889 find all of the keys from the hash.
1891 Added user_context arguments to the SilcHashFunction,
1892 SilcHashCompare and SilcHashDestructor to deliver user specified
1895 Added new fuctions silc_hash_table_find[_all]_ext to do
1896 extended lookup with specified hash and compare functions and
1897 specified user contexts.
1899 Added new function silc_hash_table_add_ext to add the key
1900 with specified hash function and user context.
1902 Added new function silc_hash_table_foreach to traverse all
1903 entrys in the hash table. Added SilcHashForeach callback
1906 Added new function silc_hash_table_del_by_context to delete
1907 the entry only if the context associated with the key matches.
1909 Affected files are lib/silcutil/silchashtable.[ch].
1911 * Removed silc_hash_[server/client/channel]_id and added just
1912 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1913 silc_hash_id_compare to compare two ID's using as the hash table
1914 comparison function. Added also silc_hash_data to hash
1915 binary data and silc_hash_data_compare to compare it.
1917 * Removed silc_idlist_find_client_by_hash as it is not needed
1918 anymore. Affected file silcd/idlist.[ch].
1920 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1921 to use internally the SilcHashTable. The new ID Cache is a lot
1922 faster than the old one. Some of the ID Cache interface was also
1923 rewritten and obsolete and stupid functions were removed.
1925 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * Added entry_count field to the SilcHashTable to keep the number
1928 of the entries in the table. Implemented the function
1929 silc_hash_table_rehash. Added new function
1930 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1932 Fixed a minor bug in silc_hash_table_free.
1934 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1935 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1936 into the lib/silcutil/silcutil.[ch].
1938 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Implemented a collision resistant hash table into the
1941 lib/silcutil/silchashtable[ch]. See the header and the source
1942 for the SilcHashTable API.
1944 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Merged dotconf version 1.0.2 into lib/dotconf.
1948 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Do not compile anything in lib/silcsim/* if the SIM support
1951 is not enabled. The tree should now compile without problems
1954 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1956 * Compiled the SILC under cygwin. Compiled and tested briefly
1957 without problems. More tests needed. The SIMs didn't compile
1960 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1962 * Fixed possible crash in silc_get_username in the
1963 lib/silcutil/silcutil.c.
1965 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Fixed a va_arg in silc/client_ops.c.
1969 * Oops, RC5 routines were named AES and caused some problems
1970 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1972 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1974 * Added new SilcIDIP structure into the lib/silccore/id.h and
1975 replaced the old `ip' fields from all SILC ID's to that type.
1976 This is a step towards IPv6 support.
1978 The silc_id_get_len takes now the ID as an extra argument.
1979 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1980 both IPv4 and IPv6 based ID's.
1982 The affected files are lib/silccore/id.[ch] and other files
1983 around the tree using these routines.
1985 * Removed the ID length arguments in server from various
1986 silc_server_send_notify_* routines -> they are not needed
1989 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Fixed memory leak in silc_encode_pem_file in the file
1992 lib/silcutil/silcutil.c.
1994 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Check minor version as well in the SKE. Affected files are
1997 silcd/protocol.c and lib/silcclient/protocol.c.
1999 * Added --identifier option to the server so that an identifier
2000 can be when creating the public key for the server. Affected
2001 file is silcd/silcd.c.
2003 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2004 lib/silccrypt/silcpkcs.c.
2006 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Register default ciphers and stuff when using -C option with
2009 the server. Affected file sildc/silcd.c.
2011 * Put back the servers public key filename format, it is better
2012 than the new one. For now, the client keys are saved with the
2013 new filename format. The affected file silc/client_ops.c.
2015 * Implemented the Cipher API for the rest of the ciphers that
2016 did not implement it or implemented it the wrong way.
2018 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Register default ciphers and stuff when using the -S option
2021 in the client. Affected file silc/silc.c. Same also when
2022 creating new key pair with -C option.
2024 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Fixed the silc_verify_public_key client operation function to
2027 save the public keys differently. The fingerprint is now
2028 used as filename and not the hostname. This way also the
2029 client keys are saved uniquely and not with hostnames. The
2030 affected file is silc/client_ops.c.
2032 * Trimmed the silc_hash_fingerprint function to remove extra
2033 whitespaces from the end of the fingerprint. The affected
2034 file is lib/silccrypt/silchash.c.
2038 * Added silc_cipher_register_default function to register all
2039 default ciphers. It can be used when configuration files
2040 does not exist and the application does not want any specific
2041 ciphers in any specific order.
2043 The SilcDList is now used as silc_cipher_list dynamically
2044 allocated cipher list. Removed the static list all together
2045 and now all ciphers must be allocated to the dynamic list.
2046 The silc_cipher_alloc routine was changed to check only the
2049 All silc_cipher_* routines that used to return int returns
2052 The affected files lib/silccrypt/silccrypt.[ch].
2054 * The same thing was done to silc_hash_* as for silc_cipher_*
2055 routines. Affected files lib/silccrypt/silchash.[ch].
2057 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2058 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2059 Added also silc_pkcs_[un]register[_default] functions.
2060 Removed the data_context from the PKCS API.
2062 * Added silc_hmac_register_default function to register default
2063 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2064 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2065 to unregister all hmacs at once.
2067 * Register the default ciphers, hash functions, PKCSs and HMACs
2068 if client's configuration file does not exist. The affected
2071 * The client did not load the hash functions from the SIM
2072 modules at all. Added support for this. Affected file is
2073 silc/clientconfig.c.
2075 * When decoding public key with silc_pkcs_public_key_decode, check
2076 the supported algorithm only if PKCS are registered. Affected
2077 file lib/silccrypt/silcpkcs.c. The same was done with the
2078 silc_pkcs_private_key_decode.
2080 * Fixed the SILC List routines to keep the list always in order.
2081 It used to change the list's order when traversing the list but
2082 not it preserves the order. Affected file lib/trq/silclist.h.
2084 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added the client library to use the SilcSocketConnection's
2087 reference counter (by silc_socket_dup) to prevent the bug that
2088 the socket object may be freed underneath async operation.
2090 * The name resolv library checking fixes in the configure.in.pre.
2093 * Created new version of the protocol drafts for future
2094 development. The -03 drafts are the ones that will be changed
2095 in the trunk now and the -02 will remain as they are.
2097 * Send list of CUMODE notifys to the router when announcing
2098 the channel users to the router. Affected file silcd/server.c.
2099 If the router receiving channel founder CUMODE for a channel
2100 that already has channel founder it will send CUMODE notify
2101 to the sender to remove the channel founder rights from the
2102 announced client. Affected file silcd/packet_receive.c.
2104 * The CUMODE notify may now use Server ID as well as the entity
2105 who changes the mode. Updated protocool specs.
2107 * Updated INSTALL and README files.
2109 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * New web pages in the http://silc.pspt.fi. The pages was
2116 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Implemented the [DenyConnectin] config section in the server.
2119 Added silc_server_config_denied_conn to check whether incoming
2120 connection is denied. Affected file silcd/serverconfig.[ch].
2122 * Do not check the ports when checking the incoming configuration
2123 data if the port is 0, meaning any. Affected file is
2124 silcd/serverconfig.c.
2126 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * Fixed buffer overflow in silc_string_compare in the file
2129 lib/silcutil/silcutil.c.
2131 * Fixed double free in silc_server_command_leave in the file
2134 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Fixed the version checking in the server. Affected file is
2139 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Fixed the configuration data fetching when accepting new
2142 connections in the server. Affected file silcd/server.c.
2144 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Added `sender_entry' argument to the function
2147 silc_server_packet_relay_to_channel so that we can check
2148 whether some destination actually belongs to the same route
2149 the sender belongs (ie, we must not resend the packet to the
2150 sender). Affected file silcd/packet_send.[ch].
2152 * Added `servername' field to the SilcClientEntry in the server
2153 to hold the name of the server where client is from. Affected
2154 file is silcd/idlist.h.
2156 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Moved the channel message encrypting in the router betwen
2159 router connections from silc_server_channel_message to the
2160 silc_server_packet_relay_to_channel since we want to check
2161 whether we have anybody channel before encrypting anything.
2162 Affected files silcd/packet_[receive/send].c.
2164 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Fixed the [AdminConnection] server config section to support
2167 multiple entries. Affected file silcd/serverconfig.c.
2169 * Added support into the server to check the validity of the
2170 incoming connection before executing any KE or authentication
2173 * The connection configuration is now saved to the KE and
2174 connection auth protocol contexts and not fetched anymore in
2175 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2177 * The local hosts listenning address and port is also resolved
2178 now when starting the server. We want to have the socket object
2179 to include the real address and port for the listener. Added
2180 new function silc_net_check_local_by_sock into the files
2181 lib/silcutil/silcnet.[ch].
2183 * Fixed a broadcast bug in server -> do not broadcast if we
2186 * Fixed a routing bug. Do not route broadcast packets ever.
2187 Broadcast packets must be processed always and not routed since
2188 they may be destined to some other host than yourself and thus
2189 would get routed without no good reason. Affected file is
2192 * Added function silc_server_config_is_primary_route to check
2193 whether primary router connection has been configured (a router
2194 configuration that we are initiating). If there is not, we
2195 will assume that there is only two routers in the SILC network
2196 and we will use the incoming router connection as our primary
2197 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2199 * Changed the order of the broadcasting. Broadcast _after_ the
2200 packet has been processed not before. Affected file is
2203 * Fixed a [ClientConnection] parsing bug. The port was never
2204 parsed correctly thus resulting to port 0. Affected file
2205 silcd/serverconfig.c.
2207 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2208 argument and did not set the broadcast packet flag. Affected
2209 file silcd/packet_send.c. Fixed same bug in the function
2210 silc_server_send_notify as well.
2212 * If we receive NEW_ID packet for our own ID in the server, ignore
2215 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Removed the nickname from the Private Message Payload.
2220 Updated the code and the protocol specs.
2222 * Updated protocol specs for submitting to the IETF.
2224 * Tweaked the Random Number Generator a bit. Affected file
2225 lib/silccrypt/silcrng.c. Exported a new function
2226 silc_rng_[global]_add_noise which can be used to add more
2229 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Do not parse packets with different timeout when protocol
2232 is active -> may cause problem with rekey. Affected file
2235 * When server receives signoff notify it must not create
2236 new channel key if the client is on any channels since the
2237 sender of the signoff notify will create it.
2239 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Added printing of error messages during SKE protocol from the
2242 failure packet sent by server during SKE. Affected file
2245 * Removed the client's failure_callback handling with timeout
2246 and handle it immediately when received.
2248 * The SKE library returned wrong type in SUCCESS and FAILURE
2249 packets. They must be 32 bit MSB not 16 bit MSB.
2251 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Ok, rewrote the logic of the re-key and now it seems to work.
2254 I tested it on high traffic with frequent re-keys without
2255 problems. Added hmac_receive (and renamed hmac to hmac_send)
2256 in SilcClientConnection in lib/silcclient/client.h and
2257 in SilcIDListData in silcd/idlist.h. Also, removed the
2258 SilcPacketParserContext's cipher and hmac fields as they are
2259 not needed anymore and actually caused some problems when
2260 the ciphers and hmac's changed underneath the packet parser.
2262 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * If re-key protocol is active then process the incoming packets
2265 synchronously since we must assure that icoming packets encrypted
2266 with the old key is processed before the new keys is set to
2267 use. This is true other packets than for REKEY packets.
2268 Affected file silcd/server.c. The same was done to client library
2269 as well, affected file lib/silcclient/client.c.
2271 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Fixed bug in client and server to accept the force send if
2274 the packet is send from silc_[server/client]_packet_process
2275 function. Otherwise the packets are never delivered, oops.
2277 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Disable force sending of packets when REKEY protocol is active.
2280 We must assure that no packet is sent directly when rekey is
2281 performed. All packets must be sent through packet queue.
2282 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2283 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2284 function is silc_[server/client]_packet_send_real to check
2287 * Replaced the SIM paths from example config files to
2288 /usr/local/modules. Also, make install creates now
2289 /usr/local/silc/logs directory to hold all the SILC server
2292 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Made the configure.in.pre work on Solaris. Patch by salo.
2296 * Made all ciphers compatible with non-x86 machines. Defined
2297 CBC mode macros into lib/silccrypt/ciphers_def.h.
2299 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Fixed the make install.
2303 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * When MAC computation fails the silc_packet_decrypt returned 0
2306 even though it was supposed to return -1. Fixed this. The
2307 affected file is lib/silccore/silcpacket.c.
2309 * Do not replace the config files in /etc/silc (in make install)
2310 if they already exist. Affected file ./Makefile.am.
2312 * Do not send re-key packets immediately but through packet queue.
2313 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2315 * Changed silc_net_check_host_by_sock to return FALSE if the
2316 IP/DNS could not be resolved. Though, it returns the IP address
2317 now even if it could not resolve it (but returns also FALSE).
2318 Affected file lib/silcutil/silcnet.[ch].
2320 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added silc_pkcs_decode_identifier to decode the public key's
2323 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2324 Added also silc_pkcs_free_identifier. Added also new context
2325 SilcPublicKeyIdentifier.
2327 * Added -S option to the silc client. It is used to dump the
2328 contents of the specified public key file.
2330 * Changed the PKCS api to return the public key length when
2331 setting the public key.
2333 * Fixed a fatal bug in the public and private key file loading.
2334 Affected file lib/silccrypt/silcpkcs.c.
2336 * Execute the packet parsing for client with zero (0) timeout
2337 if the protocol is active. Affected file silcd/server.c.
2339 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Made the key generation options to the silcd program. Added
2342 -C option, equivalent to client's option.
2344 * Added new [ServerKeys] config section to the server. It
2345 configures the server's public and private key.
2347 * Defined generic Public Key Payload into the protocol
2348 specification to send specific type of public keys and
2351 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2352 public key or certificate.
2354 * Implemented the GETKEY command to the server and to the
2355 client library and on user interface.
2357 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Made preliminary `make install' work.
2361 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Added SilcServerRekey context into silcd/idlist.h.
2365 * Added the PFS support as defined in the specification to the
2366 SKE protocol. Affected files lib/silcske/*.c.
2368 * Added `ske_group' field to the SilcServerRekey context to hold
2369 the number of the SKE group that is used with PFS in re-key.
2370 Affected file silcd/idlist.h.
2372 * Added PFS re-key support to the server. Affected file is
2375 * Added silc_protocol_cancel to cancel execution of the next
2376 state of the protocol. Affected file is
2377 lib/silccore/silcprotocol.[ch].
2379 * Added the re-key support with and without PFS to the client
2380 library. Re-key is performed once in an hour, by default.
2382 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2383 Added silc_client_rekey_callback and silc_client_rekey_final.
2384 Affected files are lib/silcclient/protocol.[ch] and
2385 lib/silcclient/client.[ch].
2387 * Removed the `hmac_key' and `hmac_key_len' fields from the
2388 SilcClientConnection structure; not needed. Affected file is
2389 lib/silcclient/client.h.
2393 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Do not ask whether user wants to use the negotiated private key
2396 for private messages, just use it. Affected file is
2397 silc/local_command.c.
2399 * Added `send_enc_key' and `enc_key_len' fields to the
2400 SilcIDListData structure since they are needed in the re-key
2401 phase. Affected file is silcd/idlist.[ch].
2403 * Implemented the simple re-key protocol into the server.
2404 Affected files silcd/server.c and silcd/protocol.[ch]. The
2405 re-key will be performed once in an hour, by default.
2407 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2408 Added silc_server_rekey, silc_server_rekey_callback and
2409 silc_server_rekey_final.
2411 * Removed Tunneled flag from the protocol. Updated the code
2412 and the specifications.
2414 * Adde `pfs' field to the SilcIDListData to indicate whether
2415 the PFS is to be performed in the re-key. Affected file is
2418 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2421 int64 of at least the xintXX size. If void * is less that 4
2422 bytes uint32 * will be used. Defined bool as boolean.
2424 * Changed _ALL_ unsigned long and unsigned int to uint32,
2425 unsgined short to uint16 in the source tree.
2427 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2428 not handle clients that has entry->data.registered == FALSE.
2429 They are not in the network anymore. Affected file is
2432 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Implemented the sending of the SERVER_SIGNOFF notify in the
2435 server. Affected file is silcd/server.c.
2437 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2438 Added also silc_notify_payload_encode_args into the
2439 lib/silccore/silcnotify.[ch].
2441 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2442 Affected file silcd/packet_receive.c.
2444 * Implemented the SERVER_SIGNOFF notify handling in the client
2445 library. Affected file lib/silcclient/client_notify.c. Also,
2446 implemnted the printing of the SERVER_SIGNOFF info to the
2447 application. Affected file silc/client_ops.c.
2449 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2450 if the deleting was successful. Affected file silcd/idlist.[ch].
2452 * Added support for public key authentication in the connection
2453 authentication protocol in the client library. Affected file
2454 lib/silcclient/protocol.c.
2456 * Changed the server's silc_idlist_get_clients_by_* interface
2457 to support already allocated array so that new entries may be
2458 added to pre-allocated array. Affected file silcd/idlist.[ch].
2459 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2460 and command replies.
2462 * All command reply functions in the server now calls the
2463 pending command callback even if error occured. This way the
2464 error will be delivered to the client as well. Affected files
2465 silcd/command.c and silcd/command_reply.c.
2467 * Fixed INFO command to return local server's info if no server
2468 was provided. Affected file lib/silcclient/command.c.
2470 * Removed RESTART command for good. Updated the code and the
2473 * Rewrote parts of the task system. It is a bit simpler now.
2474 Removed unsued task priorities. The affected files are
2475 lib/silcutil/silctask.[ch].
2477 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Moved the USERS printing from the library to the application.
2480 Affected files lib/silcclient/command.c and silc/client_ops.c.
2482 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Added channel key re-key support. The re-key is perfomed
2487 only by the router and is done once in an hour. Added `rekey'
2488 field to the SilcChannelEntry in the server. Affected files
2489 silcd/server.c and silcd/idlist.h.
2491 * Added silc_task_unregister_by_context into the file
2492 lib/silcutil/silctask.[ch].
2494 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Added SILC_UMODE_GONE mode to indicate when the client is not
2497 present in the SILC network. Added also support to the local
2498 command AWAY that will set this mode. Added support of showing
2499 "xxx is gone" in WHOIS command. The USERS command shows the
2500 gone status as well.
2502 * Fixed setting server and router operator privileges in the
2503 server's UMODE command. Affected file silcd/command.c.
2505 * Merged the SKE KE1 and KE2 payloads into one payload. The
2506 new KE payload is equivalent to the old KE2 payload.
2508 Cleaned up the SKE Start Payload parsing. It now uses the
2509 simple buffer unformatting to do the parsing. A lot faster
2512 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2513 to the SKE that is used to indicate whether both of the SKE
2514 parties should perform authentication. By default only the
2515 responder performs authentication. By setting this flag also
2516 the initiator must do authentication. By default it is unset
2517 since in normal SKE case, client to server connection, only
2518 the responder should do authentication. When doing SKE between
2519 two clients both should perform authentication. Updated the
2520 code and the protocol specs.
2522 * A little fix to IDENTIFY command in the server. Search the
2523 client first by hash not nickname. Affected file is
2526 * Fixed the silc_client_close_connection to support closing
2527 the client to client connections wihtout deleting too much
2528 data. Affected file lib/silcclient/client.c.
2530 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2531 are received if protocol used to be active but is not anymore
2532 the application would crash due to NULL pointer dereference.
2533 Affected files silcd/server.c and lib/silcclient/client.c.
2535 * Added `hash' field to the SilcClientConnection to include
2536 the hash function negotiated in the SKE protocol.
2538 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2539 to set the channel founder authentication data. A client can
2540 claim the founder rights later by providing the authentication
2541 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2542 This way the channel founder can regain the channel founder
2543 privileges even it is left the channel. This works only on
2544 local server and the client must be connected to the same
2545 server to be able to regain the founder rights. Updated the
2546 protocol specs accordingly.
2548 Added support to the CMODE command in the client to set the
2549 founder auth data. Read the README to see how to set it.
2551 Added support to the CUMODE command to claim the founder
2552 rights. Read the README to see how to do it.
2554 Added support for the founder authentication to the Channel
2555 Entry in the server. Affected file silcd/idlist.h.
2557 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2558 server's CMODE command. Affected file silcd/command.c.
2560 * Added the following new functions into lib/silccore/silcauth.[ch]:
2561 silc_auth_get_method and silc_auth_get_data.
2563 * The server now saves the remote hosts public key to the
2564 SilcIDListData pointer. Affected file silcd/protocol.c.
2566 * The normal server now does not remove the channel entry from
2567 the cache if the founder authentication data is set. It used
2568 to remove it if the founder was the last one on the channel on
2569 the server and left the channel. The auth data is saved and
2570 if the channel is re-joined later the old entry is used with
2571 the old auth data. Affected files silcd/command_reply.c and
2574 * Removed the `pkcs' field from the SilcIDListData structure
2575 in the server; it is not used. Affected file silcd/idlist.h.
2577 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Fixed packet processing on slow links. Partial packets were
2580 never re-processed because the incoming data buffer was cleared
2581 by the application. Application must not directly clear the
2582 sock->inbuf, the packet processing routines handle it. Fixed
2583 this in client library and in server.
2585 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Fixed the WHOIS and IDENTIFY send reply function to really
2588 check whether to send list or just one entry. Affected file
2591 * Cleaned up the LEAVE command's channel key distribution. The
2592 affected file silcd/command.c.
2594 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2595 can enforce the channel mode as well. In that case the ID
2596 includes the ID of the server. The code now enforces the
2597 mode change if the router have different mode than the server.
2599 * The notify client operation with CMODE_CHANGE notify can now
2600 return NULL client_entry pointer if the CMODE was not changed
2601 by client. Application must check for this.
2603 * Added <Server ID> argument to INFO command to support server
2604 info fetching by Server ID.
2606 * Added silc_server_announce_get_channel_users to get assembled
2607 packets of channel users of the specified channel. Affected
2608 file silcd/server.[ch].
2610 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2611 was freed underneath the ID Cache.
2613 * Re-announce clients when the server received CHANNEL_CHANGE
2614 notify from the router. Affected file silcd/packet_send.c.
2616 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2619 crashed since it did not handle the fact that there is no cipher
2620 called "3" and didn't check the error condition. Now fixed.
2622 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2623 flag. It can be used to send message requests.
2625 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Implemented the RESTART command in the client.
2629 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2630 notice type messages. Added notice printing to the user
2633 * The channel keys are not re-generated if the channel's mode
2634 is PRIVKEY, ie private key on the channel exists. Affected
2635 files silcd/server.c and silcd/command.c.
2637 * Fixed a little bug in channel message delivery when channel
2638 private keys are set in the server. Affected file is
2639 silcd/packet_send.c.
2641 * Changed the setting on channel->on_channel = TRUE from the
2642 silc_client_save_channel_key to the JOIN command reply. The
2643 key payload is not received if the private channel key is set.
2644 Affected file lib/silcclient/command_reply.c and the
2645 lib/silcclient/client_channel.c.
2647 * When the CMODE_CHANGE notify is sent and the channel private
2648 key mode is removed the channel key must be re-generated in
2649 other cells as well. Added this support for the router in the
2650 silcd/packet_receive.c.
2652 * Added new local command NOTICE to send notice message on
2653 channel. Affected file silc/local_command.[ch].
2655 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Added new local command ME to the client. It is used to send
2658 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2659 some action. Affected file silc/local_command.[ch].
2661 * Changed channel_message and private_message client operations
2662 to deliver the message flags to the application. Added also
2663 the `flags' arguments to the silc_client_send_channel_message
2664 and silc_client_send_private_message functions. Affected file
2667 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Redefined the Private Message Payload to support private message
2670 keys and to support the new private message flags. Updated
2671 the protocol specs. Flags makes it possible to have for example
2672 CTCP style messages.
2674 * Added new type SilcPrivateMessagePayload and defined an API
2675 for it in the lib/silcclient/silcprivate.[ch].
2677 * Tested private message private keys successfully. Tested the
2678 private message key set, unset and list commands with the new
2681 * Redefined the Channel Message Payload to include the channel
2682 message flags (equal with private message flags) to support
2683 for example CTCP style messages.
2685 * Defined some of the message (for channel and private message)
2686 flags. Updated the protocol specs and added the flags to the
2687 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2689 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Added SilcKeyAgreementStatus type to the key agreement routines
2692 to indicate the current status and error if one occured.
2693 The status types are defined in the lib/silcclient/silcapi.h.
2695 * Added new local command KEY that is used to set and unset private
2696 keys for channels, set and unset private keys for private messages
2697 with remote clients and to send key agreement requests and
2698 negotiate the key agreement protocol with remote client. The
2699 key agreement is supported only to negotiate private message keys,
2700 it currently cannot be used to negotiate private keys for channels,
2701 as it is not convenient for that purpose.
2703 * Fixed a minor pending callback setting bug in the function
2704 silc_client_get_client_by_id_resolve, now the function works.
2705 Affected file lib/silcclient/idlist.c.
2707 * Added function silc_net_get_local_port to get local bound
2708 port by socket. Added to lib/silcutil/silcnet.[ch].
2710 * Added `sockets' and `sockets_count' fields to the SilcClient
2711 object. They hold the sockets of the listenning sockets in
2712 the client. Listenning sockets may be for example the key
2713 agreement server. Affected file lib/silcclient/client.[ch].
2714 Added functions the silc_client_add_socket and the
2715 silc_client_del_socket. They are exported to the application
2718 * Added ~./silc/clientkeys to support other client's public keys.
2720 * Renamed verify_server_key client operation to verify_public_key
2721 and added one argument to indicate the type of the connection
2722 (server, client etc.).
2724 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Added silc_server_connection_auth_request to handle the
2727 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2728 silcd/packet_receive.[ch].
2730 * Added silc_server_send_connection_auth_request into the
2731 silcd/packet_send.c to send the connection auth request packet.
2733 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2736 * Fixed the public key authentication in responder side in the
2737 server. The `auth_data' pointer includes the SilcPublicKey
2738 not the path to the public key. Affected file silcd/protocol.c.
2740 * Implemented the public key authentication in the initiator side
2741 in the server. Affected file silcd/protocol.c.
2743 * Removed the [RedirectClient] config section from the server
2744 configuration. Is not needed and I don't want to implement it.
2746 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Cleaned up the CMODE command in the server. It now works
2749 correctly and supports all the modes defined in the protocol.
2750 Affected file is silcd/command.c.
2752 * Added `hmac_name' field to the SilcChannelEntry in the server
2753 to hold the default HMAC of the channel. It can be set when
2754 creating the channel (with JOIN command). Affected files
2757 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2758 type to indicate the change of the current cipher and hmac
2759 on the channel. Client can safely ignore the <cipher> argument
2760 (if it chooses to do so) since the CHANNEL_KEY packet will
2761 force the channel key change anyway. The <hmac> argument is
2762 important since the client is responsible of setting the new
2763 HMAC and the hmac key into use.
2765 * Fixed the CMODE command in the client library as well.
2767 * Tested CMODE command in router environment successfully.
2769 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Show the version of the remote client (or server) when connecting
2772 to the server. It is logged to the log file. Affected file
2773 is silcd/protocol.c.
2775 * Fixed the KILLED notify handling in the client library. The
2776 client must be removed from all channels when receiving the
2779 Also, do not remove the client entry when giving the KILL
2780 command but when the KILLED notify is received.
2782 * Removed silc_idlist_find_client_by_nickname from the server.
2783 Not needed anymore. Affected files silcd/idlist.[ch].
2785 * Implemented the CHANNEL_CHANGE notify type handling to the
2786 server. Affected file silcd/server.c.
2790 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Added silc_server_send_notify_invite to send the INVITE
2793 notify between routers.
2795 * Implemented the INVITE command correctly to the server.
2797 * Implemented the INVITE notify type handling in the server.
2799 * Implemented the INVITE command to the client library and on the
2802 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Added function silc_server_get_client_resolve to find the
2805 client entry by ID from all ID lists and then resolve it
2806 (using WHOIS) if it cannot be found. Affected file is
2809 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Implemented the BAN command to the client library.
2813 * The JOIN command in the server now checks the invite list
2816 * Changed the silc_command_reply_payload_encode_va and the
2817 silc_command_payload_encode_va to support that if argument is
2818 NULL it ignores and checks the next argument. Affected file
2819 lib/silccore/silccommand.c.
2821 * Added silc_server_send_notify_ban to send the BAN notify
2822 type between routers.
2824 * Chaned the silc_notify_payload_encode to support that if
2825 argument is NULL it ignores and checks the next argument.
2826 Affected file lib/silccore/silcnotify.c.
2828 * Tested ban lists in router environment successfully.
2830 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Implemented BAN command to the server, in silcd/command.[ch].
2834 * Removed the BAN and INVITE_LIST modes from the CMODE command
2837 * Added function silc_string_match to regex match two strings.
2838 Affected files lib/silcutil/silcutil.[ch].
2840 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Redefined parts of the SilcChannelEntry in the server to support
2843 the new ban and invite lists.
2845 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Redefined the INVITE command. The same command can be used to
2848 invite individuals to the channel but also to manage the invite
2849 list of the channel (to add to and remove from the invite list).
2850 Updated the protocol specs.
2852 * Added new command SILC_COMMAND_BAN that can be used to manage
2853 the ban list of the channel. Updated the protocol specs.
2855 * Removed the channel modes: the SILC_CMODE_BAN and the
2856 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2857 in the CMODE command. The equivalent features are now available
2858 using INVITE and BAN commands. Updated the protocol specs.
2860 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2861 in the network about change in the current ban list. The notify
2862 type is not used by the client.
2864 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2865 support the invite lists.
2867 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Added new function silc_string_regexify that converts string
2870 including wildcard characters into regex string that can
2871 be used by the GNU regex library. Added into the file
2872 lib/silcutil/silcutil.[ch].
2874 Added silc_string_regex_combine to combine to regex strings
2875 into one so that they can be used as one regex string by
2876 the GNU regex library. Added into the file
2877 lib/silcutil/silcutil.[ch].
2879 Added silc_string_regex_match to match two strings. It returns
2880 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2882 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Imported GNU regex to the soruce tree into lib/contrib.
2885 Fixed some compiler warning from the regex.c.
2887 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Fixed MOTD command in the server to work in router environment.
2891 * Fixed the MOTD command in the client library to support
2892 the server argument in the command.
2894 * Added `nickname_len' argument to the silc_idlist_add_client
2895 in the server, as the `nickname' argument may be binary data
2898 * Added silc_idlist_get_channels to return all channels from
2901 * Implemented LIST command to the server. Affected file is
2904 * Implemented the LIST command to the client library and on the
2907 * Added [<user count>] argument to the LIST command reply.
2908 With private channels the user count is not shown.
2910 * Updated TODO and README.
2912 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * The client entry's data.registered must be TRUE even with
2915 global client entry on global client list. The data.registered
2916 is used to check whether the client is anymore in the network,
2917 for example with WHOWAS command so it must be valid.
2919 * Fixed the WHOWAS command in the server. It now actually works
2920 in router environment. Added function into silcd/command_reply.c
2921 silc_server_command_reply_whowas_save.
2923 * Added silc_idlist_purge function to the silcd/idlist.c
2924 to periodically purge the ID Cache.
2926 * Fixed INFO command in the server. It works now in router
2927 environment. Added <server name> argument to the INFO command
2928 reply. Updated the protocol specs.
2930 * Fixed minor bug in silc_idcache_purge to not purge if the
2931 expire value is zero.
2933 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2934 they were buggy because of the WHOWAS information.
2936 * Fixed local command MSG to handle the async resolving of
2937 the remote client properly. It used to fail the first MSG.
2938 Affected file silc/local_command.c.
2940 * Added `data_len' field to SilcIDCache context.
2942 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Update TODO. Todo in commands in the server.
2946 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2949 used by routers as broadcast packet to inform other routers
2950 about the changed user mode.
2952 Implemented the notify handling in the server. Affected file is
2953 silcd/packet_receive.c. Added the function
2954 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2956 * Added new generic Channel Payload and deprecated the New Channel
2957 Payload. The New Channel Payload is now the generic Channel
2960 * Added new argument `mode' to the silc_server_send_new_channel
2961 as it is required in the Channel Payload now.
2963 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2964 and created a new and real SilChannelPayload to represent the
2965 new generic Channel Payload. Implemented the encode/decode
2966 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2968 * Added silc_server_get_client_channel_list to return the list
2969 of channels the client has joined for WHOIS command reply.
2970 Affected file silcd/server.[ch].
2972 * Implemented the channel list sending in the WHOIS command reply
2973 in server and in the client.
2975 Implemented the channel list displaying on the user interface
2976 as well. Affected file silc/client_ops.c.
2978 * Added silc_channel_payload_parse_list to parse list of Channel
2979 Payloads. It returns SilcDList list of SilcChannelPayloads.
2980 Client for example can use this function to parse the list of
2981 channels it receives in the WHOIS command reply. The caller
2982 must free the list by calling silc_channel_payload_list_free.
2983 Affected files lib/silccore/silcchannel.[ch].
2985 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Added one new argument <user mode> to the WHOIS command reply
2988 to return the mode of the user in SILC. Updated the protocol
2991 Implemented it to the server and client.
2993 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Fixed the mode printing on the user interface on joining.
2996 Affected file silc/client_ops.c.
2998 * Implemented the UMODE command and user modes in general to the
2999 client library and to the user interface.
3001 * Implemented the UMODE command to the server.
3003 * The server now sends UNKNOWN_COMMAND error status if client sends
3004 unknown command. Affected file silcd/command.c.
3006 * All server commands now handle the command identifier the right
3007 way when sending the command reply to the client. The client can
3008 use to identify the command replies with the identifier.
3010 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Added silc_server_get_client_route to resolve the route to
3013 the client indicated by the client ID. Affected file is
3016 * Added silc_server_relay_packet as general function to relay
3017 packet to arbitrary destination. This deprecates functions
3018 like _send_private_message_key, _relay_notify etc. Affected
3019 file is silcd/packet_send.[ch].
3021 Removed silc_server_send_key_agreement,
3022 silc_server_send_private_message_key and
3023 silc_server_packet_relay_notify functions from the file
3024 silcd/packet_send.[ch].
3028 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3029 server. Affected file silcd/packet_receive.[ch].
3031 * Implemented the KILL command to the client. Implemented the
3032 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3033 Affected files lib/silcclient/command[_reply].c and
3034 lib/silcclient/client_notify.c. Implemented the KILL notify
3035 printing in the user inteface.
3037 * Fixed a lot silc_parse_nick memory leaks from the client
3038 library in the file lib/silcclient/command.c.
3040 * Changed the silc_server_send_notify_on_channels's `sender'
3041 argument from SilcSocketConnection to SilcClientEntry to
3042 check the sender as entry and not as connection object and not
3043 to send to the client provided as argument. The affected file
3044 is silcd/packet_send.[ch].
3046 * The notify packets that are destined directly to the client used
3047 to not to be processed by the server. Now changed that and the
3048 server processes all notify packets. After relaying the packet
3049 to the client the notify packet is processed in the server.
3051 * The silc_server_free_client_data now checks whether there is
3052 pending outgoing traffic for the client and purges the data to
3053 the network before removing the client entry.
3055 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3058 an client is killed from the SILC Network. Updated the protocol
3061 Added new function silc_server_send_notify_killed to the
3062 silcd/packet_send.[ch].
3064 * Added function silc_server_packet_relay_notify to relay notify
3065 packets that are destined directly to a client. In this case
3066 the server does not process the notify packets but merely relays
3067 it to the client. Affected file silcd/packet_send.[ch].
3069 Added also silc_server_packet_process_relay_notify to check
3070 whereto relay the notify. Affected file is
3071 silcd/packet_receive.[ch].
3073 * Implemented the KILL command to the server.
3077 * Added the backup schema desgined last fall to the protocol
3078 specs for everyone to see. The specification is in the
3079 *-spec-xx.txt draft and the packet type definitions for the
3080 backup routers is in *-pp-xx.txt draft. Thusly, added also
3081 new packet type SILC_PACKET_CELL_ROUTERS.
3083 * A big security problem in the implementation discovered. The
3084 signoff of an client did not cause new channel key generation
3085 which it of course should've done. The channel keys must be
3086 always re-generated when client leaves (or signoffs) the channel.
3087 The silc_server_remove_from_channels funtion now handles
3088 the channel key re-generation.
3090 * Added `sender' argument to the silc_server_send_notify_on_channels
3091 to not to send the client provided as argument. Affected file
3092 silcd/packet_send.[ch].
3094 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Implemented OPER and SILCOPER commands into the server and
3099 * Added silc_auth_verify and silc_auth_verify_data to verify
3100 the authentication directly from the authentication payload.
3101 It supports verifying both passphrase and public key based
3102 authentication. Affected file lib/silccore/silcauth.[ch].
3104 * Added `hash' field to the SilcIDListData structure. It is the
3105 hash negotiated in the SKE protocol. Affected file is
3108 * Slight redesigning of the SilcAuthPayload handling routines.
3109 Do not send SilcPKCS but SilcPublicKey as argument.
3111 * Implemented the public key authentication support to the
3112 serverconfig. The public key is loaded from the provided path
3113 and saved as authentication data to void * pointer. Thus,
3114 changed the unsigned char *auth_data to void *auth_data;
3116 * Fixed SHUTDOWN command to send the reply before the server
3117 is shutdown. :) Affected file silcd/command.c.
3119 * Fixed fatal bug in CONNECT command. The hostname was invalid
3120 memory and server crashed. Affected file silcd/command.c.
3122 * Fixed fatal bug in CLOSE command. The server_entry became
3123 invalid but was referenced later in the command. Affected file
3126 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Fixed fatal bug in failure packet handling. Server ignored
3129 the failure and thus crashed when it came.
3133 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3136 that the command may be executed only once in (about) 2 seconds.
3137 The old SILC_CF_LAG flag is same but allows command bursts up
3138 to five before limiting.
3140 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3141 server code. Various commands now includes the CF_LAG_STRICT
3142 flag to disallow any kind of miss-use of the command.
3144 * Fixed the silc_buffer_unformat to not to allocate any data
3145 if the length of the data is zero. It used to allocate the
3146 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3148 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Changed the format of AdminConnection configuration section
3151 in the server. Added username of the admin to the format.
3152 Affected files silcd/serverconfig.[ch].
3154 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3155 to return admin configuration data by host, username and/or
3158 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3160 * Implemented WHOWAS command to the server. Added the functions:
3162 silc_server_command_whowas_parse,
3163 silc_server_command_whowas_send_reply,
3164 silc_server_command_whowas_from_client and
3165 silc_server_command_whowas_from_server
3167 * Added <Client ID> argument to the WHOWAS command reply. Updated
3168 the protocol specs accordingly.
3170 * Implemented WHOWAS command and command_reply to the client
3173 Implemented the WHOWAS printing on the user interface.
3175 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Added new argument to the WHOWAS command reply, the real name.
3178 It is an optional argument. Updated the protocol specs.
3180 * Added SilcIDCacheDestructor callback that is registered when
3181 the SilcIDCache is allocated. The callback is called when
3182 an cache entry in the ID Cache expires, or is purged from the
3183 cache. Added into lib/silccore/idcache.[ch].
3185 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3186 to destruct the client entries when the cache entry expires.
3187 Other ID Cache's in server and in the client library ignores
3190 * If the ID Cache entry's `expire' field is zero then the entry
3191 never expires. Added boolean `expire' argument to the
3192 silc_idcache_add function in the lib/silccore/idcache.[ch].
3193 If it is TRUE the default expiry value is used.
3195 * Added silc_server_free_client_data_timeout that is registered
3196 when client disconnects. By default for 5 minutes we preserve
3197 the client entry for history - for WHOWAS command.
3199 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Added support to the server to enforce that commands are not
3202 executed more than once in 2 seconds. If server receives
3203 commands from client more frequently, timeout is registered
3204 to process the commands. Affected file silcd/command.c.
3205 Added new function silc_server_command_process_timeout.
3207 * Changed NICK_NOTIFY handling in client library to check that
3208 if the client's nickname was changed, so there is no need to
3209 resolve anything from the server.
3211 * Removed error printing from the WHOIS and IDENTIFY commands.
3212 If error occurs then it is ignored silently in the client library.
3213 The application, however, may map the received error to
3214 human readable error string. The application currently maps
3215 the NO_SUCH_NICKNAME error to string.
3217 * Made the command status message public to the application. Moved
3218 them from lib/silcclient/command_reply.c to
3219 lib/silcclient/command_reply.h. The application can map the
3220 received command status to the string with the
3221 silc_client_command_status_message function.
3223 * Added check to the server to check that client's ID is same
3224 as the Source ID in the packet the client sent. They must
3227 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Added dist-bzip hook to the Makefile.am to make bzip2
3230 compressed distributions.
3232 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Server now enforces the maximum length for the nickname and
3235 the channel as protocol specification dictates. 128 bytes for
3236 nickname and 256 bytes for channel name.
3238 * Moved the WHOIS printing to the application. The client libary
3239 does not print out the WHOIS information anymore, the application
3240 must do it. Renamed silc_client_command_reply_whois_print to
3241 the silc_client_command_reply_whois_save.
3243 The client's idle time is also sent to the application now, and
3244 the idle is shown on screen.
3246 * Added silc_client_command_reply_identify_save to save the
3247 received IDENTIFY entries.
3249 * Do not check for channel private keys in message sending and
3250 reception if the channel does not have the PRIVKEY mode set.
3251 Affected file lib/silclient/client_channel.c.
3253 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3256 just surfaced after chaning the JOIN procedure.
3258 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Added silc_client_get_clients_by_list to get client entries
3261 from Client ID list, that is returned for example by JOIN
3262 and USERS command replies. The application should use this
3263 function for example when JOIN command reply is received to
3264 resolve the clients already on the channel (library does not
3265 do that anymore as USERS command reply is not used in the JOIN
3266 procedure anymore). Affected files lib/silcclient/silcapi.h and
3267 lib/silcclient/idlist.c.
3269 * JOIN command reply and USERS command reply returns now SilcBuffer
3270 pointers instead of unsigned char pointers when returning
3271 the client list and mode list.
3273 * Added <Client ID> argument to the JOIN command reply, mainly
3274 for the server to identify for which client the command was
3275 originally sent. Updated protocol specs accordingly.
3277 * Added SilcDlist private_key pointer to the SilcChannelEntry
3278 in the client to support the channel private keys. Affected
3279 file is lib/silcclient/idlist.h.
3281 * Added SilcChannelPrivateKey argument to the function
3282 silc_client_send_channel_message so that application can choose
3283 to use specific private ke if it wants to. If it is not provided,
3284 the normal channel key is used, unless private keys are set.
3285 In this case the first (key that was added first) is used
3286 as the encryption key.
3288 * Implemented the support for channel private key handling.
3289 Implemented the following functions:
3291 silc_client_add_channel_private_key,
3292 silc_client_del_channel_private_keys,
3293 silc_client_del_channel_private_key,
3294 silc_client_list_channel_private_keys and
3295 silc_client_free_channel_private_keys
3297 Affected file lib/silcclient/client_channel.c.
3299 * Added the support for the private keys in the channel message
3300 sending and encryption and in the message reception and
3301 decryption. Affected funtions are
3302 silc_client_send_channel_message and silc_client_channel_message.
3304 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added SKE's key verify callback to the client library's
3307 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3309 * Removed the statement that server (or router) must send USERS
3310 command reply when joining to the channel so that the client
3311 knows who are on the channel. Instead, the client list and
3312 client's mode list is now sent in the JOIN command reply to the
3313 client who joined channel. This is better solution.
3315 * Added function silc_server_get_users_on_channel and function
3316 silc_server_save_users_on_channel to the silcd/server.[ch].
3318 * Removed function silc_server_command_send_users from the
3321 * Do not show topic on the client library anymore. The topic is
3322 sent in the command reply notify to the application and the
3323 application must show the topic now.
3325 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Added client searching by nickname hash into the IDENTIFY and
3328 WHOIS commands in the server as they were clearly missing from
3329 them. Affected file is silcd/command.c.
3331 * Fixed a bug in private message receiving in the client library.
3332 The remote ID was freed and it wasn't supposed, now it is
3335 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Minor fix to the channel payload; allocate the data area, as it
3338 needs to be of specific length.
3340 * If the key agreement port is zero then the operating
3341 system will define the bound port. Affected files are
3342 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3344 * Added new function silc_channel_payload_decrypt into the file
3345 lib/silccore/silcchannel.[ch].
3347 * Moved the channel message etc, check from silc_packet_decrypt
3348 to applications. The library calls now a generic
3349 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3350 when the packet is either normal or special. This was done to
3351 allow more wide range of checking that was not allowed when
3352 the code was in library. Now applications can do virtually any
3353 checks to the packet and return to the library the decision how
3354 the packet should be processed. Affected files are
3355 lib/silccore/silcpacket.[ch].
3357 Added silc_server_packet_decrypt_check to the server and
3358 silc_client_packet_decrypt_check to the client library.
3360 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3361 to send with specified source and destination information.
3363 * Channel message delivery between routers was broken after the
3364 channel key distribution was fixed earlier. The channel key
3365 was used be to distributed to other routers as well which is not
3366 allowed by the protocol. Now this is fixed and channel keys
3367 really are cell specific and the channel message delivery between
3368 routers comply with the protocol specification.
3370 * Fixed various commands in server to check also the global list
3371 for the channel entry and not just the local list. The affected
3372 file silcd/command.c.
3374 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Added assert()s to buffer formatting and unformatting routines
3377 to assert (if --enable-debug) when error occurs. Affected
3378 file: lib/silcutil/silcbuffmt.c.
3380 * Changed to auto-reconnect to check whether the remote host is
3381 router and register the re-connect timeout if it is. It used
3382 to check that whether we are normal server, but router must do
3383 auto-reconnect with another router as well. Affected file
3386 * Removed the [<key len>] option from CMODE command as the cipher
3387 name decides the key length, nowadays. See the defined ciphers
3388 from the protocol specification.
3390 * Added [<hmac>] option to the CMODE command to define the HMAC
3391 for the channel. Added SILC_CMODE_HMAC channel mode.
3393 * Added [<hmac>] option for the JOIN command so that user can
3394 select which HMAC is used to compute the MACs of the channel
3397 * Added Hmac field to the Channel Message Payload. The integrity
3398 of plaintext channel messages are now protected by computing
3399 MAC of the message and attaching the MAC to the payload. The
3400 MAC is encrypted. Now, it is clear that this causes some
3401 overhead to the size of the packet but rationale for this is that
3402 now the receiver can verify whether the channel message decrypted
3403 correctly and also when private keys are set for the channel the
3404 receiver can decrypt the packet with several keys and check from
3405 the MAC which key decrypted the message correctly.
3407 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3408 lib/silccrypt/silccipher.[ch].
3410 * Added silc_hash_len to return the digest length into the
3411 lib/silcrypt/silchash.[ch].
3413 * Rewrote parts of Silc Channel Payload interface in the
3414 lib/silccore/silcchannel.[ch]. The encode function now also
3415 encrypts the packet and parse function decrypts it.
3417 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Fixed a minor formatting bug in the SKE's key material processing.
3420 It actually might have processed the keys wrong way resulting
3423 * Redefined the mandatory HMAC algorithms and added new algorithms.
3424 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3425 and hmac-md5 truncated to 96 bits. The mandatory is now
3426 hmac-sha1-96. Rest are optional (including the one that used
3427 to be mandatory). Rationale for this is that the truncated HMAC
3428 length is sufficient from security point of view and can actually
3429 make the attack against the HMAC harder. Also, the truncated
3430 HMAC causes less overhead to the packets. See the RFC2104 for
3433 * Added new [hmac] configuration section. The SKE used to use
3434 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3435 is of course wrong. The official names that must be proposed in
3436 the SKE are the ones defined in the protocol specification
3437 (hmac-sha1-96 for example). The user can configure any hmac
3438 using any hash function configured in the [hash] section. At
3439 least, the mandatory must be configured.
3441 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3443 * Added HMAC list to the SKE proposal list. It has now both
3444 hash algorithm list and HMAC list. This makes the protocol
3445 incompatible with previous versions. The SKE now seems to work
3446 the way it is supposed to work, for the first time actually.
3448 * Defined plain Hash algorithms to the protocol specification.
3451 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Implemented support for key agreement packets into the server.
3454 Added functions silc_server_key_agreement and
3455 silc_server_send_key_agreement. Other than these functions,
3456 server has nothing to do with this packet.
3458 * Added support for private message key packets into the server.
3459 Added functions silc_server_private_message_key and
3460 silc_server_send_private_message_key.
3464 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3465 called in the protocol's final callback instead in the END
3466 protocol state. This makes a little more sense and in the same
3467 time in client we can use the same protocol routines for normal
3468 key exchange and to key agreement packet handling as well.
3470 * Added to both client's and server's KE protocol context the
3471 SilcSKEKeyMaterial pointer to save the key material. We will
3472 bring the key material to the protocol's final callback by doing
3473 this. The final callback must free the key material.
3475 * Added SKE's packet_send callback into client's KE protocol
3476 context so that the caller can choose what packet sending function
3477 is used. This way we can use different packet sending when
3478 doing normal SKE when doing key agreement packet handling (in
3479 the key agreement packet handling we do not want to encrypt
3482 * Implemented the responder side of the key agreement routines
3483 in the client. The client can now bind to specified port and
3484 accept incoming key negotiation. The key material is passed
3485 to the application after the protocol is over.
3487 * Implemented the processing of incoming Key Agreement packet
3488 in the client. Added function silc_client_key_agreement to
3491 * Implemented the intiator side of the key agreement routines
3492 in the client. The client can now initiate key agreement with
3493 another remote client. The key material is passed to the
3494 application after the protocol is over.
3496 * Created client_keyagr.c to include all the key agreement
3499 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3500 SILC_TASK_CALLBACK except that it is not static.
3502 * Created client_notify.c and moved the Notify packet handling
3503 from the client.[ch] into that file.
3505 * Created client_prvmsg.c and moved all private message and
3506 private message key routines from the client.[ch] into that file.
3508 * Create client_channel.c and moved all channel message and
3509 channel private key routines from the client.[ch] into that file.
3511 * Changed silc_client_get_client_by_id_resolve to resolve with
3512 WHOIS command instead of IDENTIFY command, in the file
3513 lib/silclient/idlist.c.
3515 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Implemented the SKE's responder side to the Client library.
3519 * When FAILURE is received to the protocol do not trust it
3520 blindly. Register a timeout to wait whether the remote closes
3521 the connection as it should do it, only after that process the
3522 actual failure. This was changed to both client and server.
3524 * Added client_internal.h to include some of the structures
3525 there instead of client.h in lib/silcclient/.
3527 * Added function silc_task_unregister_by_callback to unregister
3528 timeouts by the callback function.
3530 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Some "Incomplete WHOIS info" errors has been appearing on the
3533 log files. Took away the entry->userinfo check from WHOIS
3534 reply sending. The entry->userinfo is now " " if client did not
3535 provide one. I thought this was fixed earlier but something
3536 is wrong still. Let's see if the error still appears.
3538 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Fixed a minor bug in the login when the channel key is
3541 re-generated in the server. It used to generate the key in
3542 wrong order and thus caused problems in the channel traffic.
3544 * Fixed a minor bug in channel key distsribution after
3545 KICK command. The key was not sent to the router even though
3548 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Added silc_ske_process_key_material_data as generic routine
3551 to process any key material as the SILC protocol dictates. The
3552 function is used by the actual SKE library but can be used by
3553 applications as well. This relates to the private message keys
3554 and the channel private keys since they must be processed the
3555 same way the normal SILC session keys. The protocol dictates
3556 this. Affected files: lib/silcske/silcske.[ch].
3558 Added also silc_ske_free_key_material to free the
3559 SilcSKEKeyMaterial structure.
3561 * Defined silc_cipher_set_key function to set the key for
3562 cipher without using the object's method function. The affected
3563 files: lib/silccrypt/silccipher.[ch].
3565 * Implemented silc silc_client_add_private_message_key,
3566 silc_client_add_private_message_key_ske,
3567 silc_client_del_private_message_key,
3568 silc_client_list_private_message_keys and
3569 silc_client_free_private_message_keys functions in the
3572 Added functions silc_client_send_private_message_key to send
3573 the Private Message Key payload and silc_client_private_message_key
3574 to handle incoming Private Message Key payload.
3576 * Added Cipher field to the Private Message Key payload to set
3577 the cipher to be used. If ignored, the default cipher defined
3578 in the SILC protocol (aes-256-cbc) is used.
3580 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Removed lib/silcclient/ops.h file.
3584 Redefined parts of the SILC Client Library API. Created new
3585 file silcapi.h that deprecates the ops.h file and defines the
3586 published Client Library API. Defined also private message key
3587 API and channel private key API into the file.
3589 This is the file that the application must include from the
3590 SILC Client Library. Other files need not be included by
3591 the application anymore.
3593 * Added new key_agreement client operation callback and also
3594 defined the Key Agreement library API for the application.
3596 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3599 is used by clients to request key negotiation between another
3600 client in the SILC network. If the negotiation is started it
3601 is performed using the SKE protocol. The result of the
3602 negotiation, the secret key material, can be used for example
3603 as private message key.
3605 Implemented the Key Agreement payload into the files
3606 lib/silccore/silauth.[ch].
3608 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Redefined ciphers for the SILC protocol. Added some new ciphers
3611 and defined the key lengths for the algorithms. Changed the
3612 code accordingly. The default key length is now 256 bits.
3614 * Fixed SKE key distribution function silc_ske_process_key_material
3615 when the key length is more than 128 bits. The default key
3616 length in SILC is now 256 bits.
3618 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3619 to indicate unsupported algorithm.
3621 * Renamed rijndael.c to aes.c and all functions as well.
3623 * Fixed a long standing channel key setting bug in client library.
3624 Weird that it has never surfaced before.
3626 * Fixed bug in channel deletion. If the entire channel is removed
3627 then it must also delete the references of the channel entry
3628 from the client's channel list as the client's channel entry and
3629 the channel's client entry share same memory.
3631 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Implemented CONNECT and SHUTDOWN commands in the client.
3635 * Implemented CLOSE command to the client.
3637 * Added the function silc_idlist_find_server_by_name into the
3638 files silcd/idlist.[ch].
3640 Added the function silc_idlist_find_server_by_conn into the
3641 files silcd/idlist.[ch].
3643 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * DIE command was renamed to SHUTDOWN. Updated the both code
3648 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3649 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3651 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3654 * Added function silc_server_create_connection function to create
3655 connection to remote router. My server implementation actually
3656 does not allow router to connect to normal server (it expects
3657 that normal server always initiates the connection to the router)
3658 so the CONNECT command is only good for connecting to another
3661 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3664 or some other client was kicked from the channel.
3666 Implemented the handling of the notify type to both client
3669 Implemented silc_server_send_notify_kicked to send the KICKED
3670 notify. It is used to send it to the server's primary router.
3672 * Implemented the KICK command into server and client.
3674 * Added `query' argument to the silc_idlist_get_client function
3675 to indicate whether to query the client from server or not if
3678 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3679 to indicate that the client is not channel founder.
3683 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Removed the rng context from SilcPacketContext structure and
3686 changed that the packet routine uses the Global RNG API.
3688 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Added support for quit message that client can "leave" on the
3691 channel when it quits the SILC. It is ditributed inside the
3692 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3694 Added silc_server_free_client_data that will take the
3695 signoff message as argument.
3697 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3699 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Updated parts of the protocol specification to keep it up
3704 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3707 payloads in one packet.
3709 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3710 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3711 use now the new List flag.
3713 * Also deprecated the following packet types: REPLACE_ID,
3714 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3716 * Added list support for Notify packet in server.
3718 * Added silc_server_send_notify_channel_change to send the
3719 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3720 the silc_server_send_replace_id.
3722 * Added silc_server_send_notify_nick_change to send the
3723 NICK_CHANGE notify type. Deprecates the function
3724 silc_server_send_replace_id.
3726 * Added silc_server_send_notify_join to send the JOIN notify type.
3727 Deprecates the function silc_server_send_new_channel_user.
3729 * Added silc_server_send_notify_leave to send LEAVE notify type.
3730 Deprecates the function silc_server_send_remove_channel_user.
3732 * Added silc_server_send_notify_cmode and
3733 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3734 types. Deprecates the silc_server_send_set_mode function.
3736 * Added SERVER_SIGNOFF notify type to indicate that server has
3737 quit. This means that all clients on the channel from that
3738 server will drop. This can be also used when netsplit happens.
3740 Deprecated REMOVE_ID packet type since it is not needed anymore
3743 Added silc_server_send_notify_server_signoff to send the
3744 SERVER_SIGNOFF notify type. Deprecates the function
3745 silc_server_send_remove_id.
3747 Added also silc_server_send_notify_signoff to send the
3748 SIGNOFF notify type.
3750 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3751 SILC protocol from this day on. Changed the protocol
3752 specification as well.
3754 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3755 notify type. It is used between routers to notify about
3756 topic changes on a channel.
3758 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3761 * Partly updated the protocol specification to comply with the
3762 changes now made. It is still though a bit outdated.
3764 * The JOIN notify type now takes one extra argument <Channel ID>.
3765 The packet used to be destined to the channel but now the
3766 JOIN type may be sent as list thus it is impossible to
3767 destine it to any specific channel. By adding this argument
3768 it is again possible.
3770 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Added CREDITS file. The CHANGES and CREDITS file will appear
3773 in the distribution as well.
3775 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3778 types in the server's silcd/packet_receive.c.
3780 * Implemented CMODE and CUMODE to work in router environment.
3782 * Fixed minor encoding and decoding buglet from the
3783 lib/silccore/silcmode.c.
3785 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3788 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3790 * Changed all SilcConfigServer* and silc_config_server* to
3791 SilcServerConfig* and silc_server_config*, respectively.
3794 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Associated the ID (client or server ID) to the Authentication
3797 Payload to avoid any possibility of forging. Updated the
3798 protocol specification and the code accordingly.
3800 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * The RSA key length is now save to the RsaKey context in the
3803 key generation process in lib/silccrypt/rsa.c. The key length
3804 is now used to figure out the maximum size of the block allowed
3805 to be encrypted/signed.
3807 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3808 is equivalent to the silc_mp_mp2bin but does not allocate any
3811 * Changed silc_mp_mp2bin API to take length argument. If it is
3812 non-zero then the buffer is allocated that large. If zero, then
3813 the size is approximated using silc_mp_sizeinbase, which however
3816 * Created Global RNG API which is global RNG that application can
3817 initialize. After initializing, any routine anywhere in the
3818 code (including library) can use RNG without allocating a new
3819 RNG object. This was done to allow this sort of use of the
3820 RNG in code that has no chance to allocate RNG object. All
3821 applications currently allocate this and many routines in the
3822 library use this. Affected file lib/silccrypt/silcrng.[ch].
3824 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3825 it to use the Global RNG API.
3827 * Defined Authentication Payload into protocol specification that
3828 is used during SILC session to authenticate entities. It is
3829 used for example by client to authenticate itself to the server
3830 to obtain server operator privileges.
3832 Implemented this payload into the lib/silccore/silcauth.[ch].
3833 Implemented also routines for public key based authentication
3834 as the new protocol specification dictates.
3836 Moved definitions of different authentication methods from
3837 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3839 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3840 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3841 silc_pkcs_verify_with_hash functions into the file
3842 lib/silccrypt/silcpkcs.[ch].
3844 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * The client entry's userinfo pointer must be always valid.
3847 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3848 will fail since it requires the userinfo. Now, the userinfo
3849 is allocated as "" if actual userinfo does not exist. Actually,
3850 it must exist and it is totally Ok to drop client connections
3851 that does not announce the userinfo. However, we will make
3852 this workaround for now.
3854 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3855 to return the remote port by socket.
3857 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3860 SILC_SERVER_PENDING_EXEC and added an new macro
3861 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3862 data or when error occurs while processing the pending command.
3864 Added new argument `destructor' into silc_server_command_pending
3865 and to the SilcServerCommandPending object. This destructor is
3866 now called after calling the pending callback or if error occurs
3867 immediately. If error occurs the actual pending callback won't
3868 be called at all - only the destructor. The destructor may be
3869 NULL if destructor is not needed.
3871 All this applies for client library code as well. Similar
3872 changes were made there as well for the pending commands.
3874 In the client, the application must now allocate the
3875 SilcClientCommandContext with the silc_client_command_alloc
3878 * Added reference counter to the SilcServerCommandContext. Added
3879 function silc_server_command_alloc and silc_server_command_dup
3882 Same type of functions added to the client library for the same
3885 * Removed the cmd_ident from IDListData away since it is now
3886 global for all connections. It is the command identifier used
3887 in command sending and with pending commands. The affected file
3890 * Added reference counter to the SilcSocketConnection objecet to
3891 indicate the usage count of the object. The object won't be
3892 freed untill the reference counter hits zero. Currently only
3893 server uses this, and client ignores it. The client must be
3894 set to use this too later. The affected files are
3895 lib/silccore/silcsockconn.[ch]. Added also the function
3896 silc_socket_dup to increase the reference counter.
3898 This was mainly added because it is possible that the socket
3899 is removed underneath of pending command or other async
3900 operation. Now it won't be free'd and proper DISCONNECTING
3901 flags, etc. can be set to avoid sending data to connection that
3902 is not valid anymore.
3904 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3905 the connection. After that it sets SILC_SET_DISCONNECTED.
3906 It is, however, possible that the socket data is not still freed.
3907 The silc_server_packet_process now checks that data is not
3908 read or written to connection that is DISCONNECTED. The socket
3909 get's freed when the reference counter hits zero.
3911 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Changed the client operation API: channel_message operation's
3914 `sender' is now the client entry of the sender, not the nickname
3915 and the `channel' is the channel entry, not the channel name.
3917 In the private_message operation the `sender' is now also the
3918 client entry of the sender not the nickname.
3920 Affected file is lib/silcclient/ops.h and all applications
3921 using the client operations.
3923 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Moved the calling of ops->connect() from connect_to_server_final
3926 into receive_new_id functin since that is the point when the
3927 client is actually allowed to send traffic to network. The
3928 affected file is lib/silcclient/client.c.
3930 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3933 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3934 (if needs broadcasting) instead of broadcasting the packets one
3935 by one which would make a burst in the network traffic.
3937 * Added `broadcast' argument to the functions in silcd/server.[ch]
3938 silc_server_create_new_channel[_with_id] to indicate whether
3939 to send New Channel packet to primary router.
3941 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Added new function into the silcd/server.[ch] files:
3944 silc_server_create_new_channel_with_id to create new channel with
3945 already existing Channel ID.
3947 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3948 lib/silccore/silcpacket.h. This packet is used t send list of
3949 Set Mode payloads inside one packet. Server uses this to set
3950 the modes for the channels and clients on those channels, that it
3951 announced to the router when it connected to it. The protocol
3952 specification has been updated accordingly.
3954 * The silc_server_new_channel did not handle the packet coming
3955 from normal server as it normally does not send that. However,
3956 when it announces its channels it does send it. Implemented
3957 the support for that.
3959 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3960 into the file lib/silccore/id.h.
3962 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Fixed memory leaks in the functions silc_idlist_del_client,
3965 silc_idlist_del_channel and silc_idlist_del_server in the file
3966 silcd/idlist.c. All of those leaked like a sieve.
3968 * Fixed some small memory leaks in the client's function
3969 silc_client_notify_by_server.
3971 * Added functions into silcd/server.c: silc_server_announce_clients,
3972 silc_server_announce_channels and silc_server_announce_server.
3973 These functions are used by normal and router server to announce
3974 to its primary router about clients, channels and servers (when
3975 router) that we own. This is done after we've connected to the
3978 These functions effectively implements the following packet types:
3979 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3980 and SILC_PACKET_NEW_ID_LIST.
3982 * Added new functions into the silcd/packet_receive.[ch]:
3983 silc_server_new_id_list, silc_server_new_channel_list and
3984 silc_server_new_channel_user_list to handle the incoming
3985 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3987 * Added support of changing Channel ID in the function
3988 silc_server_replace_id. If the server that announces a channel
3989 to the router already exists in the router (with same name but
3990 with different Channel ID), router is responsible to send
3991 Replace ID packet to the server and force the server to change
3992 the Channel ID to the one router has.
3994 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3995 client that the Channel ID has been changed by the router. The
3996 normal server sends this to the client. Client must start using
3997 the new Channel ID as the channel's ID.
3999 Implemented handling of this new type into lib/silcclient/client.c
4000 into the function silc_client_notify_by_server.
4002 * Added new function silc_idlist_replace_channel_id into the files
4003 silcd/idlist.[ch] to replace the Channel ID.
4005 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Call silc_server_command_identify_check always when processing
4008 the IDENTIFY command in silcd/command.c
4010 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4013 send keepalive packets. The packet can be sent by clients,
4014 servers and routers.
4016 Added function silc_socket_set_heartbeat into the file
4017 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4018 If not set, the heartbeat is not performed. The actual
4019 heartbeat is implemented in the low level socket connection
4020 library. However, application is responsible of actually
4023 Added silc_server_send_heartbeat to send the actual heartbeat
4024 packet into silcd/packet_send.[ch]. Server now performs
4025 keepalive with all connections.
4027 * Added silc_task_get_first function into lib/silcutil/silctask.c
4028 to return the timeout task with shortest timeout. There was a bug
4029 in task unregistration that caused problems. TODO has been
4030 updated to include that task system must be rewritten.
4032 * The client library will now resolve the client information when
4033 receiving JOIN notify from server for client that we know but
4034 have incomplete information.
4036 * Rewrote parts of silc_server_remove_from_channels and
4037 silc_server_remove_from_one_channel as they did not remove the
4038 channel in some circumstances even though they should've.
4040 * Encryption problem encountered in server:
4042 The LEAVE command used to send the Channel Key packet to the
4043 router immediately after generating it. However, the code
4044 had earlier sent Remove Channel user packet but not immediately,
4045 ie. it was put to queue. The order of packets in the router
4046 was that Channel Key packet was first and Remove Channel User
4047 packet was second, even though they were encrypted in the
4048 reverse order. For this reason, MAC check failed. Now, this
4049 is fixed by not sending the Channel Key packet immediately but
4050 putting it to queue. However, this is more fundamental problem:
4051 packets that are in queue should actually not be encrypted
4052 because packets that are sent immediately gets encrypted
4053 actually with wrong IV (and thus MAC check fails). So, packets
4054 that are in queue should be encrypted when they are sent to
4055 the wire and not when they put to the queue.
4057 However, the problem is that the current system has not been
4058 designed to work that way. Instead, the packet is encrypted
4059 as soon as possible and left to the queue. The queue is then
4060 just purged into wire. There won't be any fixes for this
4061 any time soon. So, the current semantic for packet sending
4064 o If you send packet to remote host and do not force the send
4065 (the packet will be in queue) then all subsequent packets to the
4066 same remote host must also be put to the queue. Only after the
4067 queue has been purged is it safe again to force the packet
4070 o If you send all packets immediately then it safe to send
4071 any of subsequent packets through the queue, however, after
4072 the first packet is put to queue then any subsequent packets
4073 must also be put to the queue.
4075 Follow these rules and everything works fine.
4077 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Added new function silc_server_remove_clients_by_server to
4080 remove all client entries from ID list when the server connection
4081 is lost. In this case it is also important to invalidate all
4082 client entires as they hold the invalid server entry. This
4083 fixes fatal bug when server has lost connection and will reconnect
4086 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Made some sanity checks to silc_server_daemonise like to check
4089 whether the requested user and group actually exists.
4091 * Added sanity check to SKE's silc_ske_responder_finish to check
4092 that the public and private key actually is valid.
4094 * Invalidate the client's nickname when receiving Replace ID
4095 packet and the Client ID is being replaced. This means that the
4096 server will query the nickname if someone needs it (client)
4099 * Sort the ID Cache in client library when the ID Cache data
4100 has changed (needs sorting).
4102 * Do not allow for SILC client to create several connections to
4103 several servers. The client does not support windows right now
4104 and generating multiple connections causes weird behaviour.
4106 Irssi-silc client does support windows and can handle several
4107 connections without problems, see: www.irssi.org and SILC plugin.
4109 * Fixed some places where client was added to the IDList. The
4110 rule of thumb is following (in order to get everything right):
4111 If the client is directly connected local client then the
4112 `connection' argument must be set and `router' argument must be
4113 NULL to silc_idlist_add_client function. If the client is not
4114 directly connected client then the `router' argument must
4115 bet set and the `connection' argument must be NULL to the
4116 silc_idlist_add_client function.
4118 * The funtion silc_server_packet_send_local_channel actually did
4119 not check whether the client was locally connected or not. It
4120 does that now. Fixed a bug related to LEAVE command.
4122 * Fixed Remove Channel User payload parsing bug in server's
4123 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4125 * The server's silc_server_save_channel_key now checks also the
4126 global ID list for the channel as it might not be in the local
4127 list. Fixed a bug related to LEAVE command.
4129 * Is this the end of the [<unknown>] buglet that has been lurking
4130 around for a long time? A little for loop fix in server's
4131 silc_server_command_whois_parse that is used by both IDENTIFY
4132 and WHOIS command. At least, this was a clear bug and a cause
4133 of one type of [<unknown>] buglet.
4135 * WHOIS and IDENTIFY commands call the function
4136 silc_server_command_[whois/identify]_check function even if
4137 we are not router server.
4139 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Added --with-gmp configuration option. If set the GMP
4142 is always compiled in the SILC source tree. If not set then
4143 it is checked whether the system has the GMP3 installed. If
4144 it has then the GMP won't be compiled (the system's headers
4145 and library is used), if it doesn't have it then the GMP is
4146 compiled in the SILC source tree.
4148 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Changed RSA private exponent generation to what PKCS #1
4151 suggests. We try to find the smallest possible d by doing
4152 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4153 not security fix but optimization.
4155 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Added new config entry [Identity] to fork the server and run
4158 it as specific user and group. A patch from Bostik.
4160 * Imported Dotconf configuration library into lib/dotconf.
4161 This will be used to create the SILC configuration files later.
4162 It will appear in the distsribution after this commit.
4164 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * A big code auditing weekend happening. Auditing code for
4167 obvious mistakes, bugs and errors. Also, removing any code
4170 Removed files for being obsolete:
4172 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4173 inline in the file lib/silcutil/silcbuffer.h)
4175 o lib/silcutil/silcbufutil.c (the header has inline versions)
4177 Changed code to fix possible error conditions:
4179 o The buffer formatting routines now check that the destination
4180 buffer really has enough space to add the data. This applies for
4181 both buffer formatting and unformatting
4182 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4183 unformatting was changed to accomodate following rules:
4184 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4185 sent to the function while XXX_*STRING will not allocate or copy
4186 the data into the buffer. Instead it sets the pointer from the
4187 buffer into the pointer sent as argument (XXX_*STRING used to
4188 require that the pointer must be allocated already). This change
4189 makes this whole thing a bit more consistent and more optimized
4190 (note that the data returned in the unformatting with XXX_*STRING
4191 must not be freed now). The routines return now -1 on error.
4193 o Tried to find all code that use buffer_format and buffer_unformat
4194 and added return value checking to prevent formatting and
4195 especially unformatting errors and possible subsequent fatal
4198 o Changed ske->x and ske->KEY to mallocated pointers in
4199 lib/silcske/silcske.h. Fixed possible data and memory leak.
4201 o Added return value checking to all *_parse* functions. Fixed
4202 many memory leaks as well.
4204 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4205 so that buffer overflows would not happen. All code now also
4206 checks the return value as it can fail.
4208 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Added reconnection support to server if the normal server looses
4211 its connection to the router (for example if router is rebooted).
4212 The server performs normal reconnection strategy implemented
4213 to the server. Affected file silcd/server.c.
4215 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Added new packet type SILC_PACKET_SET_MODE that is used to
4218 distribute the information about changed modes (for clients,
4219 channels and clients channel modes) to all routers in the
4220 network. Updated the protocol specification accordingly.
4222 Added functions into silcd/packet_send.c and
4223 silcd/packet_receive.c: silc_server_send_set_mode,
4224 silc_server_set_mode.
4226 Added new files silcmode.[ch] into lib/silccore that implements
4227 the encoding and decoding of Set Mode Payload. Added new type
4228 SilcSetModePayload. Moved the definitions of different modes
4229 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4231 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Oops, a little mistake in server's connection authentication
4234 protocol. The protocol is not ended with FAILURE but with
4235 SUCCESS if the authentication is Ok. :) Affected file is
4238 * Implemented NICK_CHANGE notify handling in server in the file
4239 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4240 the local clients on the channel. After the changing nickname
4241 in router environment snhould work and the [<unknown>] nickname
4242 should appear no more.
4244 The silc_server_replace_id function that receives the Replace ID
4245 payload now sends the NICK_CHANGE notify type also in the file
4246 silcd/packet_receive.c
4248 * Changed WHOIS and IDENTIFY command to support the maximum amount
4249 of arguments defined in protocol specs (3328 arguments). This
4250 fixed a bug that caused problems when there were more than three
4253 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Added extra parameter, command identifier, to the
4256 silc_client_send_command so that explicit command identifier
4259 Changed that ID list routines uses specific command identifier
4260 when sending WHOIS/IDENTIFY requests to the server so that they
4261 can be identified when the reply comes back.
4263 Affected files lib/silcclient/command.[ch],
4264 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4266 * Added `sender' argument to silc_server_packet_send_to_channel
4267 to indicaet the sender who originally sent the packet to us
4268 that we are now re-sending. Ignored if NULL. Affected file
4269 silcd/packet_send.[ch].
4271 * Added some server statistics support in silcd/server_internal.h
4272 SilcServerStatistics structure and around the server code. Also
4273 send some nice statistics information when client is connecting
4276 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Fixed channel ID decoding in server's JOIN command reply in
4279 silcd/command_reply.c
4281 * Fixed braodcasting of replace ID payload to not to send it if
4282 we are standalone server in silcd/packet_receive.c.
4284 * Fixed all channel message sending routines to not to send
4285 packets to clients that has router set, since they are routed
4286 separately in the same function earlier. Affects file
4287 silcd/packet_send.c and all channel packet sending functions.
4289 * In USERS reply, res_argv[i] are not allocated, the table
4290 is allocated. Thus changed that free the table, not its
4293 * In server's whois_check and identify_check if the client is
4294 locally connected do not send any WHOIS commands - they are not
4297 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * Fixed some minor bugs in client when sending WHOIS command. The
4300 arguments was in wrong order.
4302 * Removed statis function add_to_channel from server in
4303 silcd/command.c that was previously used with the joining but
4306 * Tested USERS command in router environment successfully with two
4307 routers, two servers and two clients.
4309 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Reorganized the USERS command and command reply in client library
4312 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4313 When the command is given by user we register a pending command
4314 callback that will reprocess the command after the reply has been
4315 received from the server. When reprocessing the packet we then
4316 display the information. Thus, the USERS information is displayed
4317 now in the command callback instead of in the command reply
4318 callback. The processing of the command is same as previously
4319 when server has sent the command reply in the JOINing process.
4321 * Added to USERS command in silcd/command_reply.c to join the client,
4322 we didn't use to know about, to the channel after we've created
4323 a client entry for it. Also, for clienet we did know already still
4324 check whether it is on the channel or not and add it if not.
4326 * Removed silc_server_command_join_notify as the function and its
4329 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Changed the client's pending command handling to the same as the
4332 server's pending command handling. It is also now possible to
4333 execute command reply functions from other command reply
4334 function as the function callbacks for commands and command
4335 replies are one and same. The pending commands are not static
4336 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4337 in client connection context. Thus, pending commands are server
4338 connection specific as it is convenient.
4340 Changed the function silc_client_command_pending and
4341 silc_client_command_pending_del and added new function
4342 silc_client_command_pending_check. Removed the
4343 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4346 * Added cmd_ident, current command identifier, to the client
4347 connection context in lib/silcclient/client.h to keep track on
4348 command identifiers used in command sending. Client's command reply
4349 function handling now supports the mandatory command identifiers.
4351 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4352 funtions in client to fully support pending command callbacks.
4354 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4355 as one of the arguments to the application in the command reply
4358 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4359 before first releasing SILC but came back. Now it is removed again
4360 and should come back nomore. The FORWARDED flag was used only
4361 by the JOINing procedure by forwarding the command packet to router.
4362 Now, the JOINing procedure has been changed to more generic (due
4363 to various router environment issues) and FORWARDED is not needed
4364 anymore for anything. The protocol specification is yet to be
4367 Now, removed silc_server_packet_forward from server and the flag
4368 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4370 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Renamed NAMES command to USERS command. The NAMES was named that
4373 due to historical reasons. Now it is renamed. Also, rewrote
4374 parts of the USERS command. The nickname list is not sent anymore
4375 by the server. Only Client ID and mode lists are sent in the USERS
4376 command. Changed this also to the protocol specification.
4378 The client now resolves the names and stuff after it receives
4379 the USERS list from the server when joining to the channel.
4381 * WHOIS and IDENTIFY commands has been changed to support multiple
4382 Client ID's per command. One can now search for multiple users
4383 in the network by sending only one WHOIS or IDENTIFY command.
4384 Changed the code and the protocol specifications.
4386 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4387 uses silc_server_command_whois_parse to parse the request. */
4389 * If normal server, do not parse the WHOIS and IDENTIFY requests
4390 before sending it to the router. Saves some time.
4392 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Fixed JOIN command on client library. Wrong number of arguments
4395 used to crash the client.
4397 * Added silc_server_channel_has_global function to check whether
4398 channel has global users or not.
4400 * Added silc_server_channel_has_local function to check whether channel
4401 has locally connected clients on the channel.
4403 * The silc_server_remove_from_one_channel now checks whether the
4404 channel has global users or not after given client was removed from
4405 the channel. It also checks whether the channel has local clients
4406 on the channel anymore. If it does not have then the channel entry
4407 is removed as it is not needed anymore.
4409 * The silc_server_notify now checks on JOIN notify whether the joining
4410 client is one of locally connected or global. If it is global then
4411 the channel has now global users on the channel and that is marked
4412 to the channel entry. Also, it now saves the global client to
4413 global list who is joining and JOINs it to the channel. This is
4414 for normal server, that is.
4416 Changed silc_server_send_notify_on_channel,
4417 silc_server_packet_relay_to_channel and
4418 silc_server_packet_send_to_channel check if we are normal server
4419 and client has router set (ie. global client) do not send the
4420 message to that client, as it is already routed to our router.
4422 * Implemented LEAVE notify type handling in silc_server_notify
4425 * Tested LEAVE command in router environment successfully. Tested
4426 with two routers, two servers and two clients.
4430 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4432 * Implemented SIGNOFF notify type handling in silc_server_notify
4435 * silc_server_remove_id now removes the client entry from all channels
4436 it has joined and thusly sends SIGNOFF notify type.
4438 * Rewrote the NAMES list generation in server by removing two excess
4439 loops. The lists are created now inside one loop.
4441 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * silc_server_remove_channel_user checks now also global list
4444 for channel and client.
4446 * silc_server_new_channel_user checks now both local and global
4447 list for channel and client. Fixed a bug in client id decoding.
4448 Used to decode wrong buffer.
4450 * silc_server_channel_message checks now both local and global
4451 list for channel entry.
4453 * Tested channel joining (hence JOIN) in router environment
4454 successfully. Tested with two routers, two servers and two
4457 * Tested channel message sending in router environment successfully.
4459 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Added silc_server_save_channel_key into server.[ch] to save the
4462 received channel key in Channel Key payload processing. It is
4463 also used in JOIN command reply handling.
4465 Equivalent function silc_client_save_channel_key added into
4466 client.[ch] into client library.
4468 * Changed JOIN command reply to send information whether the channel
4469 was created or not (is existing already) and the channel key
4470 payload. Changed protocol specs accordingly.
4472 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4473 the request was sent by ID and not by nickname. Crashed on
4476 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4479 now correctly save the received data.
4481 * silc_server_free_sock_user_data now notifies routers in the
4482 network about entities leaving the network.
4484 At the same time implemented functions silc_server_remove_id
4485 and silc_server_send_remove_id to receive and send REMOVE_ID
4486 packets. The packet is used to notify routers in the network
4487 about leaving entities. The ID removed will become invalid in
4490 * Added function silc_idlist_del_server into server. Removes and
4491 free's server entry from ID list.
4493 * silc_server_private_message function now checks, if we are router,
4494 that the destination ID really is valid ID, naturally.
4496 * In router when NEW_ID packet is received (for new client) the
4497 hash of the Client ID is saved in the ID Cache but the
4498 client->nickname is set to NULL, instead of putting the hash
4501 IDENTIFY command now also checks that client->nickname must be
4502 valid. If it is not if will request the data from the server who
4503 owns the client. Added new function
4504 silc_server_command_identify_check.
4506 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4507 to set the command to already allocated Command Payload.
4509 * Tested private message sending in router environment with two
4510 routers, two servers and two clients. Fixed minor bugs and now
4513 * Fixed segfault from client's NAMES command. Used to crash if
4516 * Forwarded packets must not be routed even if it is not destined
4517 to the receiver. Changed server code comply with this.
4519 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added `require_reverse_mapping' boolean value to ServerParams
4522 structure. If TRUE (not default) the server will require that
4523 the connecting host has fully qualified domain name.
4525 If the reverse mapping is not required and hostname could not be
4526 found the IP address is used as hostname.
4528 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Implemented version string checking to both client and server.
4531 The check is incomplete currently due to the abnormal version
4532 strings used in development version of SILC.
4534 * Changed all command functions in server to use the new
4537 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Changed char *data to unsigned char *data in ID Cache system to
4540 support binary data as ID Cache data. Changed code to support
4541 binary data in lib/silccore/idcache.c.
4543 * Renamed silc_server_packet_relay_command_reply to
4544 silc_server_command_reply as it is normal packet receiving
4545 function. Rewrote the function to accept command replys for
4546 servers and not only for clients.
4548 * Mark remote router always as registered server if we are connecting
4549 to it. Otherwise, commands sent by the router to us are ignored.
4551 * All ID List find routines now returns the ID Cache Entry pointer
4552 as well if requested.
4554 * WHOIS command works now in router environment, tested with two
4555 routers, two servers and two clients.
4557 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4558 in router environment (as it is almost equivalent to WHOIS) but
4559 hasn't been tested thoroughly. Added new functions:
4561 silc_server_command_identify_parse
4562 silc_server_command_identify_send_reply
4563 silc_server_command_identify_from_client
4564 silc_server_command_identify_from_server
4566 * Disabled route cache adding because adding two different ID's with
4567 same IP replaces the old cache entry thus giving wrong route.
4568 The entry->router->connection is always the fastest route anyway
4569 so route cache may not be needed. Of course, new routes maybe
4570 established after receiving the ID when the entry->router->connection
4571 might not be anymore the most optimal.
4573 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Add route cache for received ID for fast routing.
4577 * Added silc_server_packet_route to route received packet on router
4578 that is not destined to us.
4580 * Renamed silc_server_get_route to silc_server_route_get.
4582 * Added id_string and id_string_len fields into SilcServer to
4583 include encoded ServerID for fast comparing without excess
4584 encoding of the ID's.
4586 * Cleaned up WHOIS command on server side. Added following static
4589 silc_server_command_whois_parse
4590 silc_server_command_whois_check
4591 silc_server_command_whois_send_reply
4592 silc_server_command_whois_from_client
4593 silc_server_command_whois_from_server
4595 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4596 arguments in command replies. All command functions should be
4597 updated to use this macro.
4599 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Minor typo fixes on command reply handling on server.
4603 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added silc_server_command_add_to_channel internal routine to add
4606 the client to the channel after router has created the channel and
4607 sent command reply to the server.
4609 * Added generic silc_server_send_command to send any command from
4612 * Use static buffer with ID rendering instead of duplicating data.
4614 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Fixed a channel user mode bug when joining to a channel server gave
4617 everybody channel founder rights, oops.
4619 * We mark ourselves as the router of the incoming server connection
4620 if we are router ourselves. This way we can check in some packet
4621 sending functions whether it is locally connected server. For
4622 incoming router connections we put NULL.
4624 * For router sending packets locally means now always sending the
4625 packet cell wide; to local clients and local servers. For normal
4626 server sending packet locally means sending it to only local
4629 * Fixed the JOIN command to really work in router environment. If the
4630 channel is created it is always created by the router. Router is
4631 also responsible of making the initial joining to the channel,
4632 sending JOIN notify to the sending server and distributing
4633 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4634 does not exist server doesn't do anything else but forward the
4635 command to the router which performs everything.
4637 * Added silc_server_send_channel_key function to send the Channel Key
4640 * Added silc_server_create_channel_key to create new channel key. The
4641 channel key is now re-generated everytime someone joins or leaves
4642 a channel, as protocol dictates. Note: channel->key_len is the
4645 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4648 packet_receive.[ch] to separate packet sending and receiving
4649 routines. The server.[ch] now includes everything else including
4650 actual packet processing (writing and reading data) and other
4653 Renamed silc_server_private_message_send_internal to
4654 silc_server_send_private_message. The routine is still though
4655 used only to relay private messages as server does not send
4656 private messages itself.
4658 Renamed silc_server_new_channel to silc_server_create_new_channel
4659 and added new function sicl_server_new_channel that handles the
4660 incoming New Channel packet. Added also new sending function
4661 silc_server_send_new_channel to send New Channel Payload.
4663 * Added new function silc_server_notify to process incoming notify
4664 packet to the server/router. Server may then relay the notify
4665 to clients if needed.
4667 * Added new function silc_server_new_channel_user to process incoming
4668 New Channel User packet. Router will redistribute the packet and
4669 send JOIN notify to its local clients and locally connected servers
4670 if needed. Normal server will send JOIN notify to its local client
4671 on same channel when received this packet. Added also corresponding
4672 sending function silc_server_send_new_channel_user to sent the
4675 * Added boolean route argument to send_notif_to_channel and
4676 packet_send_to_channel functions to attempt to route the packet
4677 if it is TRUE and send only locally if it is FALSE.
4679 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * silc_server_replace_id now broadcasts the received replace ID
4682 packet if it is not broadcast packet already. The router must
4683 broadcast to inform other routers about changed ID.
4685 * Added backpointer to server's router into SilcServer context in
4686 silcd/server_internal.h.
4688 * Fixed silc_server_packet_broadcast to send correct broadcast
4691 * The channel key is now distributed to the local client as soon
4692 as it is received from the router (in router environment) so that
4693 no other packet may be sent for the channel until client has
4696 * silc_server_remove_channel_user now broadcasts the received
4697 Remove Channel User packet if it is not broadcast packet already.
4698 The router must broadcast to inform other routers about removed
4701 * Added users field into SilcPacketContext that is a reference count
4702 of the context. One can increase the reference count by calling
4703 silc_packet_context_dup which is now changed to just increase the
4704 reference count instead of duplicating the data. The reference
4705 count is decresed by calling silc_packet_context_free that will
4706 free the data after the reference count hits zero.
4708 For now on the packet context and everything allocated into it
4709 (including the raw packet from network) must be freed by calling
4710 the new silc_packet_context_free function. Added also new function
4711 silc_packet_context_alloc that must be used now to allocate the
4712 context. This also means that if a routine is asynchronous from
4713 silc_[client/server]_packet_parse_type the packet context must
4714 be duplicated by calling silc_packet_context_dup. Otherwise it
4715 gets free'd after silc_[client/server]_packet_parse_type returns.
4716 Also, one must remember that if packet is duplicated then its
4717 reference count must be decresed by calling the free function as
4718 many times as it was duplicated.
4720 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4721 from both client and server.
4723 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Made joining to a channel working in router environment.
4727 * Cleaned up JOIN command on server side and create function
4728 silc_server_command_join_channel internal routine to make the
4731 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Changed silc_command_pending list to SilcDList. Also, added
4734 `ident' field to SilcServerCommandPending structure to identify
4735 the reply and to call correct callback.
4737 Added silc_server_command_pending_check function to replace the
4738 corresnponding macro. The silc_command_pending list is not
4741 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4742 to set identifier to previously allocated Command Payload. It
4743 is used to set identifier for command when resending Command
4746 * Added silc_command_payload_encode_payload to encode Command
4747 Payload buffer from SilcCommandPayload structure.
4749 * Added silc_argument_payload_encode_payload to encode Argument
4750 payload buffer from SilcArgumentPayload structure.
4752 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Changed WHOIS command to support router connection on server side.
4755 The whois request is always sent to router unless the server is
4756 standalone server. After server has received the reply from the
4757 router will it send the reply to the client.
4759 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4760 broadcast received broadcast packet. The function is used only
4761 by router. The broadcast packet is always sent to the router's
4764 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4765 render given ID to printable string, for log files for example.
4767 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Made basic router to router connections working. At least they
4770 can now connect to each other but nothing really works the way
4771 they are supposed - yet.
4773 * Added new initiator token to RouterConnection configuration
4774 file in silcd/serverconfig.[ch]. It is used to tell whether we
4775 are the initiator to the remote router or whether we'll expect
4776 the other end to connect.
4778 * Moved registering of listener task to silc_server_init, hence
4779 the server starts listenning as soon as it is run, even if it
4780 does not have connections to other routers. Let's see how well
4783 * Changed default connection retry timeouts for more suitable in
4786 * Removed cipher and such arguments from silc_idlist_add_client
4787 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4788 Added new function silc_idlist_add_data to add the keys and stuff
4791 * Added SilcIDListData structure and added it to SilcClientEntry
4792 and SilcServerEntry as their first field in the structure. This
4793 way we can explicitly cast the ID entries to the SilcIDListData
4794 structure and get common data for the entries. In past, we had
4795 to first check what type of connection it is and then cast it to
4796 correct ID entry type. Now, we can directly cast the opaque
4797 pointer to the SilcIDListData (no matter what ID entry it actually
4798 is) and get the data needed.
4800 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4803 in some circumstances even if threre were timeout tasks, though not
4804 IO tasks, but tasks anyway. Now fixed.
4806 * Defined SilcServerConnection structure to hold connection specific
4807 stuff about directly connected servers and routers. The definition
4808 is currently in silcd/server_internal.h. I thought about having
4809 a bit more important role fro this struct but for now it is used
4810 only when connecting to other server (or router actually).
4812 * Added connecting retry support in server when connecting to
4813 router(s). The retry feature implement exponential backoff
4814 algorithm. Also, added SilcServerParams structure to hold default
4815 parameters for server. For now, it include these retry settings
4816 and are hard coded. After server is moded to be as Silc Server
4817 Library this structure will be more important.
4819 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Changed client librarys channel->clients table to SilcList and
4822 changed code accordingly.
4824 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Changed client's channel table to SilcList and changed code
4827 accordingly. Also changed SilcChannelClientEntry to include back-
4828 pointer to the channel so that client entry can use that structure
4829 as list as well and we have fast cross-reference to the channel.
4830 This change dramatically decreased the complexity of channel
4831 handling with client entry and vice versa (removed one extra
4832 loop when searching for channel entry from many functions).
4834 * Changed server->sim from table to SilcDList and changed code
4837 * NAMES command can now be used from user interface. It will show
4838 the user list on the channel, neatly.
4840 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4841 Code now saves realname of the user if it becomes available.
4843 * Renamed configure.in to configure.in.pre and made ./prepare
4844 script to automatically add correct version string to
4845 configure.in which it creates from configure.in.pre.
4847 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * NAMES command reply now shows users mode with the nickname when
4852 * Moved silc_client_ch[u]mode[_char] functions from
4853 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4854 place sucks, they are utility functions and should be in some
4857 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4859 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4862 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Added TRQ (efficient deque and list library) into lib/trq. This is
4867 a very good list library that is currently used in the SILC. Defined
4868 SilcList API over the library because I didn't like the API very
4869 much. See lib/trq/silclist.h for the API and examples of how to
4870 use the API. Fixed various places in the code to use the new
4871 SilcList API. The SilcList is meant for lists that has a structure
4872 already defined as a list. It is not suitable to add just some
4873 context to the list (in TRQ, the context is the list actually).
4875 So, I defined SilcDList that can be used for the purpose where
4876 predefined list structure does not exit. This can be used as
4877 such list. Now some context just can be added to the SilcDList.
4878 Currently this list is not used in the SILC just yet, though there
4879 are a lot places where this can replace dynamically allocated
4880 tables and I will fix these places, later, to use SilcDList.
4881 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4882 and use TRQ internally).
4884 Also fixed some annoying warning messages that the original TRQ
4885 code generated. Also minor changes to TRQ's Makefile.in.
4887 * Added support for querying by Client ID to both WHOIS and
4888 IDENTIFY commands into server, as required by the protocol.
4890 * Removed method function pointers from SilcBuffer structure. They
4891 weren't used to anything and just increased the context size for
4892 no good reason. This change also made silc_buffer_alloc and
4893 silc_buffer_free functions inline functions.
4895 * Disabled command flooding detection support until it's fixed so
4896 that it accepts commands in but does not execute them more than once
4899 * Added silc_net_localhost(), to return local hostname, into
4900 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4901 that must be initialized before calling silc_client_init.
4903 * Added new function: silc_server_send_notify_on_channels to send
4904 notify messages to all channels client has joined. It is assured
4905 that the message is sent only once per client.
4907 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4908 lib/silcutil/silcutil.[ch] as silc_format function. The new
4909 function is generic and is used by server as well, not only by
4910 the logging routines.
4912 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4913 the provided version string was not acceptable. Added new function:
4914 silc_ske_check_version into lib/silcske/silcske.h. The function
4915 must be implemented by the application (client or server) and it
4916 does not reside in the SKE library. The function checks the version
4917 string remote end sent.
4919 * Added back pointers (to opaque context and to SilcSocketConnection)
4920 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4922 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4923 duplicate packet context structure.
4925 * Changed `notify' client operation to send same arguments as client
4926 receives from server except for ID's. ID's are mapped to correct
4927 ID entry and that is returned. Also, if channel entry is not sent
4928 by server but the notify is for channel the channel entry is sent
4929 to application (otherwise application doesn't know that it is for
4930 channel (library gets it from packet's Destination ID)).
4932 * Added silc_client_remove_from_channels into client library to
4933 remove a client from all channels it has joined to. Used when
4934 received SIGNOFF notify from server. Added also new function
4935 silc_client_replace_from_channels to replace old ID entry with
4936 new ID entry on all channels. Used when received NICK_CHANGE
4939 * Fixed ID Cache list handling in silc_idlist_get_client in
4940 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4941 to get (or query) client by ID.
4943 * Updated TODO list.
4945 * Added connection authentication status message defined by the
4946 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4947 support for these into the code in client and server side.
4949 * Added generic function silc_client_send_command to send any command
4950 with variable argument list. Application should use this function
4951 to send commands if the command functions provided by the library
4952 does not suite for the application's user interface needs.
4954 * Added new `failure' client operation. Application is notified about
4955 received failure packet if client is executing a protocol. In this
4956 case the protocol's execution has failed.
4958 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4959 is required by the protocol.
4961 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4962 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4965 * Added status flag to SilcSKE object to indicate realtime status
4966 of the SKE protocol.
4968 * Application receives now exactly same command reply arguments as
4969 the library receives from server. However, if ID is received the
4970 corresponding ID entry is returned to the application (eg. Client
4971 ID is mapped to correct SilcClientEntry entry and that is returned).
4972 Changed command_reply client operation due to this change.
4974 * Changed all ID's in commands and in command replys as ID Payloads.
4975 Change affected both client and server side codes.
4977 All ID's sent in SILC network (with execption of ID's in SILC
4978 Packet header) are sent in ID Payload to support variable length
4981 * Server now notifies nick changes and notifies all clients on
4982 the channels about the new nickname (about the new Client ID,
4985 * Implemented CMODE command to change channel modes. Supports all
4986 channel modes defined by the protocol specs except ban and invite
4987 lists. (Also, private channel key mode is supported but support for
4988 setting private channel key in client is missing, thus, this mode
4989 has no effect on client side (except that server requires that the
4990 client uses private channel key and normal channel traffic does not
4993 Also, invite mode works per se, but INVITE command does not work
4994 yet correctly, so you can set channel as invite only channel but
4995 inviting clients to the channel does not work (it is yet to be
4996 thought what's the best way to do it).
4998 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4999 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5000 Implemented CUMODE command to change user's mode on the channel.
5001 Supports all modes defined by the protocol specs.
5003 * Added NAMES command reply to return users modes on the channel.
5005 * Removed unnecessary and slow ciphers from lib/silccrypt.
5007 * Set SO_KEEPALIVE option to connection sockets by default.
5009 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5011 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5012 redefined the Notify Payload into protocol specs.
5014 * Added silc_id_payload_parse_id to get ID directly from raw
5017 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5020 accept searching by Client ID as well.
5022 * Added support for LEAVE and SIGNOFF notify types in client library.
5024 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5025 to parse ID Payload from raw data.
5027 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Added flags parameter into silc_ske_assemble_security_properties
5030 function in lib/silcske/silcske.[ch].
5032 * Changed notify client operation to fit better for notify messages
5033 sent by server. The notify payload received from server is now
5034 passed to the application (after parsing it to SilcNotifyPayload).
5035 It is application's responsibility to retrieve the arguments
5036 from the payload and show the message the way it wants. The message
5037 sent by server is implementation specific.
5039 * Changed public keys to comply with the protocol specification.
5040 Old public keys are not supported anymore and are not compatible.
5042 * Removed nickname from Channel Payload as the latest draft removed
5043 it. The client must resolve the nickname from the NAMES command
5044 reply received when it joined the channel.
5046 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5048 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Fixed some errors in protocol specification drafts.
5052 * Created lib/silccore/silcnotify.c to implement Notify Payload
5053 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5054 generic payloads described by protocol specifications. The file
5055 includes implementations for ID Payload and Argument Payload.
5057 * Changed Command Payload implementation to use the new Argument
5058 Payload. Changed command_xxxx_payload to command_payload_xxxx
5059 to comply with SILC coding conventions.
5061 * Added suppport for Argument Payload handling in Notify Payload
5062 implementation as protocol requires it. Added the new support
5063 into server and client lib as well.
5065 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added support for multiple nicknames on same channel. [n] is
5068 added locally to the nickname if there are more than one same
5069 nicknames on the channel.
5071 * Server now sends all nicknames that matched WHOIS request.
5072 Client also shows the list received from server.
5074 * Added TOPIC command to client side. User can now set and show
5075 current topic on channel.
5077 * Added MOTD command to client and server. Also, server sends the
5078 motd when client connects to the server.
5080 * Changed version strings to comply ISO 8601.
5082 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Fixed protocol error handling in client library. It should now
5085 cope even if the SKE fails for some reason.
5087 * Made new protocol specification drafts for submitting to IETF.
5089 * Implemented TOPIC command to server in silcd/command.c.
5091 * Added two new notify types into lib/silccore/silcnotify.h:
5092 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5093 notify nickname change and topic setting/change on a channel.
5095 * API change of command_reply operation in client library. The
5096 application gets now the status type received from server as well.
5098 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5102 * Cras fixed and optimized the packet handling even further and
5103 it should work now. Minor change to the prototype of function
5104 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5106 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Added new function into lib/silcutil/silcschedule.[ch]:
5109 silc_schedule_with_fd to select() a specified fd. The function
5110 returns after timeout expires or data arrives or goes. The
5111 function is used by packet routines to wait that all data is
5112 received from network.
5114 * Fixed data reading from network in lib/silccore/silcpacket.c.
5115 The code now assures that all data is read from the fd and then
5116 continues packet processing. This was a bug fix since the code
5117 used to drop some data in some circumstances.
5119 * Added new function into lib/silcclient/client.[ch]:
5120 silc_client_start_key_exchange to start key exchange after
5121 connection has been established to server. The code internally
5122 now uses this funtion but its main purpose was to provide it
5123 for applications that perform their own connecting. After
5124 application has created a connection it merely calls this
5125 function to start the key exchange between client and server.
5126 The library takes care of everything else after that.
5128 Updated also lib/silcclient/README to explain the usage of
5131 * Do not send to application information that connection has
5132 been established. Application gets notified it by connect
5135 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Applied cras's patch to add silc_schedule_one function. The
5138 function runs scheduler once and returns.
5140 * Fixed the scheduler after cras messed it up. The timeout
5141 handling works now as it's supposed to work.
5143 * Added into lib/silccore/ silcnotify.h to include notify
5144 message types support. Changed silc_server_send_notify*
5145 functions, in server.[ch], to support those new notify types.
5146 Added the support for the notify types into client library,
5147 as well. Added new notify client operation into ops.h in
5150 * Changed silc_server_packet_send_to_channel to send normal
5151 packets instead of just channel message packets. The function
5152 is now used to send the notify packets to channels. It is not
5153 used to send channel message packets anymore, as server never
5156 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5157 va_arg()s as it seems to require it nowadays. I guess, if SILC
5158 is compiled with older va_arg() the new code should work anyway.
5160 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Splitted core library. Core library (lib/silccore) includes
5163 now only SILC protocol specific core (and common) components.
5164 Created new utility library (lib/silcutil) that includes more
5165 generic purpose stuff. The stuff for util library was taken
5166 from the old core library. This was minor and easy split.
5168 * Created SILC Client Library (lib/silcclient) that includes
5169 implementation of the SILC client without user interface. This
5170 was major move from silc/ directory. The code has been changed
5171 so that it is transparent towards the user interface. The
5172 silc/ directory includes now the same user interface as before
5173 and it uses the new client library. Read lib/silcclient/README.
5174 Basicly, the client library performs everything else related
5175 to SILC except user interface handling. Also, configuration
5176 files are considered to be part of user interface and library
5177 does not handle them.
5179 This change also changed a lot of structures, function naming etc.
5180 Most important change was that SilcClientWindow object was
5181 renamed to SilcClientConnection in the client library. Created
5182 also new file lib/silcclient/ops.h. Also added new files
5183 silc/local_command.[ch] and silc/client_ops.[ch].
5185 All these changes were made to make it easier for user interface
5186 designers to create what ever user interface for the SILC client
5189 It is also expected that the server will be moved to lib
5190 directory as well and SILC Server Library will be created;
5191 sometimes in the future.
5193 * Removed Local commands from lib/silccore/silccommand.h as
5194 they are application specific and new client library does not
5195 handle any of those anymore.
5197 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5198 old client implementation in silc/.
5200 * Added support for callback functions in SILC_LOG_* macros.
5201 Application can now set its own callbacks that will be called
5202 instead of using the default functions that will always print
5203 the debug messages to stderr (or stdout). Also, debugging can
5204 now be disabled by setting silc_debug to FALSE and re-enabled by
5205 setting it to TRUE. Note, that logging will still work even
5206 if debugging is disabled.
5208 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5209 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5210 silc_log_reset_debug_callbacks.
5212 * To enable debugging in silc client one must give now -d
5213 option on command line.
5215 * Changed silc_schedule_init to automatically allocate task queues
5216 if they are not allocated before calling it.
5218 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Added GMP 3.1 into math library.
5222 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5225 a channel in SILC network. The packet is used by servers and
5226 routers to notify other routers that user has left a channel.
5227 This little feature was missing until now. Added the feature
5228 to protocol specification as well.
5230 Added functions: silc_server_send_remove_channel_user and
5231 silc_server_remove_channel_user into server.[ch].
5233 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5234 lib/silccore/silcpacket.h. However, they are not implemented
5237 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Fixed joining to a channel and sending channel messages
5240 between server and router. The channel message sending should
5241 now work inside a cell.
5243 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Fixed the private message sending between server and router.
5246 The private message sending should now work inside a cell.
5248 * Added silc_server_replace_id into server.[ch] to replace
5249 existing ID in the SILC network.
5251 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5252 and silc_idlist_replace_server_id into idlist.[ch] in server.
5254 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Fixed the server to server connections. Server can again now
5257 connect to router. Router to router connections probably does
5260 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Added dynamic protocol registering support. Now protocols can
5263 registered and unregistered on the fly. Patch by cras.
5265 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Added lib/contrib directory to hold routines that some platforms
5268 don't have but are needed by SILC.
5270 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5271 into lin/contrib to provide getopt() and getopt_long() for
5272 those who don't have it.
5274 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5276 * Added AWAY command to client. When away message is set and
5277 client receives a private message packet the client automatically
5278 replies to the sender with the away message.
5280 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5281 bug seemed to be the cause of recent problems when compiling
5284 * Added version detection support to SKE protocol specification
5285 and added the new changes to the SKE implementation as well.
5286 There were other minor changes in the SKE protocol as well.
5288 Many changes in lib/silcske/silcske.[ch] and in
5289 lib/silcske/payload.[ch].
5291 * Added ^U functionality, clear input line. Patch from cras.
5293 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Mainly small bugfixes on core library. Fixed some debugging
5296 logging and buffer overflow in silclog.c.
5298 * Updated config.sub and config.guess on the distribution tree.
5300 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Added command lagging support in server. Client may execute
5303 commands now only once in two seconds.
5305 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Optimized packet reception. MAC computation and checking is now
5308 also more optimized. A lot previously duplicated code is now
5309 used as generic by both client and server.
5311 * Fixed key pair generation in clientutil.c
5313 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Added into lib/silccore/silcbufutil.[ch] new function;
5316 silc_buffer_realloc.
5318 * Moved generic packet sending/encryption functions to
5319 lib/silccore/silcpacket.[ch] from client and server. Some
5320 rewriting of the functions.
5322 * Moved all generic packet reception/decryption functions to
5323 lib/silccore/silcpacket.[ch] from client and server. The
5324 packet processing is now much cleaner in both client and server.
5325 These were major changes in both client and server.
5327 * Created many common functions in server to do packet sending.
5328 Previously code were duplicated a lot, this has been removed
5331 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Rewrote major parts of the ID cache system. Don't know
5334 whether it is better now or not but at least the API is more
5337 * Major rewrite on ID cache stuff on client because of the ID
5338 cache API changes. Added idlist.c to client.
5340 * Also major rewrite on ID cache stuff on server as well.
5341 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5342 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5343 in hand, instead they are all put into the ID cache system now.
5344 All server_idlist_* routines uses ID cache now instead of
5345 traversing its own lists (those lists does not exist anymore).
5346 SilcIDList though still exists. Also, SilcXXXEntry's are
5349 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Finally made the SKE implementation compliant to the protocol
5352 specification. All mp integers are now binary encoded as
5353 opposed being HEX encoded.
5355 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5358 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5359 functions: silc_[encode/decode]_pem. Also added function
5360 silc_encode_pem_file to PEM encode with newlines ('\n') for
5363 * SILC public keys are now encoded either PEM or binary. Same
5364 option is for private keys as well. By default private keys
5365 are binary encoded and public keys PEM encoded. Silly HEX
5366 encoding were removed.
5368 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5369 function to create fingerprints.
5371 * Fixed a bug in SHA1; does not change the original data anymore.
5373 * Partly implemented INFO command on client and server side.
5374 Fixed CLEAR command. Changes to SERVER command; show current
5375 server(s) when giving command without arguments. Added
5376 VERSION command to client.
5378 * Added check to server that unregistered connections cannot
5379 execute commands (unless it is specificly allowed).
5381 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Fixed screen refresh.
5385 * Fixed channel joining bug from client. On some circumstances
5386 client tried to join to a channel it had already joined.
5388 * Added public key verification process into client's protocol.c.
5389 The client now verifies the public key from user and saves
5390 it into ~./silc/serverkeys/ directory.
5392 Added into: clientutil.[ch]: silc_client_verify_server_key.
5394 * Changed SKE protocol's silc_ske_initiator_finish function
5395 to accept callback function that verifies the received public
5396 key. Removed old silc_ske_verify_public_key function.
5398 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5401 silc_pkcs_private_key[_data]_set.
5403 * Made the password and public authentication more cleaner in
5404 server's protocol.c.
5406 * Removed historic and obsolete protocol `channel_auth' from
5407 both client and server.
5409 * Removed wrong way of sending command status messages from
5410 server to client in server's command.c. The old way violated
5411 protocol specification.
5413 Changes to silccore/silccommand.[ch]: removed
5414 silc_command_encode_status_payload -> not needed anymore,
5415 changed silc_command_encode_payload_va to accept extra
5416 argument on variable argument list. The argument type must
5417 now be provided to the function. Also, added new function:
5418 silc_command_encode_reply_payload_va which is same as
5419 normal command_encode_payload_va except command status type
5420 is provided as extra argument.
5422 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added ~./silc directory handling. The directory includes the
5425 public and private keys for the client.
5427 Added silc_client_check_silc_dir, silc_client_create_identifier
5428 and silc_client_load_keys.
5430 * Implemented SILC protocol compliant public key. Added public
5431 and private key saving to and loading from files.
5433 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
