1 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Wrote the definition of the backup resuming protocol to the
4 protocol specification.
6 * Removed one redundant channel key generation from normal
7 server during joining procedure. Removed one redundant
8 channel key sending from server to router during joining
9 procedure. Affected file silcd/command.c.
11 * Made minor bugfixes to the backup router resuming protocol.
12 Affected file silcd/server_backup.c, server.c.
14 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Added --disable-asm configuration option. Affected files
17 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
20 * Implemented the backup resuming protocol that is used to
21 resume the primary router position in the cell after the
22 primary router comes back online. Affected files
23 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
24 and silcd/server_util.[ch].
26 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
28 * Sleep two (2) seconds after sending QUIT command to server.
29 Affected file lib/silcclient/command.c.
31 * Assure that if outgoing data buffer is pending do not force
32 send any data. Affected file silcd/packet_send.c.
34 * Assure that if outgoing data buffer is pending do not force
35 send any data. Affected file lib/silcclient/client.c.
37 * Implemented the backup router support when the primary router
38 goes down. The servers and routers can now use the backup
39 router as new primary router without loosing connectivity.
41 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
44 in the server to indicate disabled entry. All data read
45 from the connection will be ignored and no data is sent
46 for entry that is disabled. Affected files are
47 silcd/idlist.h, silcd/server.c.
49 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Created SFTP client and server test programs in the
52 lib/silcsftp/tests directory.
54 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Implemented memory filesystem (virtual filesystem) for
57 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
60 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Implemented the SFTP (SSH File Transfer Protocol) to the
63 lib/silcsftp. It includes SFTP client and SFTP server
66 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
68 * Moved lib/silccore/silcprotocol.[ch] to the
71 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
72 take variable argument list pointer as argument. Affected
73 file lib/silcutil/silcbuffmt.[ch].
75 * Added silc_buffer_set function that is used to set data
76 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
77 Affected file lib/silcutil/silcbuffer.h.
79 * Changed various routines in the core library to use the new
80 silc_buffer_set instead of allocating new buffer only for
83 * Added 64-bit value formatting and unformatting support to the
84 silc_buffer_[un]format routines. Affected file is
85 lib/silcutil/silcbuffmt.[ch].
87 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
88 to includes/bitmove.h.
90 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
92 * Fixed channel user mode saving in client library. Affected
93 file lib/silcclient/command[_reply].c.
95 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Defined the file transfer to the SILC Protocol. Added
98 new packet type SILC_PACKET_FTP and defined File Transfer
99 Payload. The mandatory file transfer protocol is SFTP
100 (SSH File Transfer Protocol). Affected file in addition
101 of the internet draft is lib/silccore/silcpacket.h.
103 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
104 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
105 is used as part of backup router protocol when the primary
106 router of the cell is back online and wishes to resume
107 the position as primary router.
109 * Redefined the MAC generation keys in the protocol. The
110 same key is not used anymore in both direction. Both
111 direction will now use different keys for sending and
112 receiving. This fixes a potential security flaw. This
113 change causes incompatibilities in the protocol.
115 * Redefined also the MAC computation from the packet.
116 An packet sequence number is now added to the MAC
117 computation. This prevents possible replay attacks against
118 the protocol. This change too causes incompatibilities
121 Added `sequence' field to the SilcPacketContext to hold
122 the current sequence number for the packet.
124 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Added `created' field to the SilcIDListData in the file
127 silcd/idlist.h to indicate the time when the entry was
130 * Added `created' field to the SilcChannelEntry too. Affected
133 * Added `creation_time' aguments to all the announcement functions
134 in the server. If it is provided then only the entries that
135 was created after the provided time frame are actually
136 announced. Affected file silcd/server.[ch].
138 * The protocol says that the Channel ID's IP address must be
139 based on the router's IP address. Added check for this in
140 the silc_server_new_channel when processing incoming New Channel
141 Payload. Affected file silcd/packet_receive.c.
143 * Print out the correct version with --version in SILC client.
144 Affected file irssi/src/silc/core/silc-core.c.
146 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
148 * Fixed WHOWAS command to check for completnes of the client
149 entry always, not just when the command is coming from client.
150 Affected file silcd/command.c.
152 * Added new function silc_server_packet_queue_purge to purge the
153 outgoing data queue to the network. After the function returns
154 it is guaranteed that the outgoing packet queue is empty.
155 Affected file silcd/packet_send.[ch].
157 * Purge the outgoing packet queue in the rekey protocol's final
158 callback to assure that all rekey packets go to the network
159 before quitting the protocol. Affected file silcd/server.c.
161 * Added silc_client_packet_queue_parse as similar function as
162 in server to the client library. The affected file is
163 lib/silcclient/client.c.
165 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
167 * Splitted silcd/server.c and created silcd/server_util.[ch]
168 for utility functions.
170 * Added new socket flag SILC_SF_DISABLED to indicate that the
171 connection is open but nothing can be sent to or received from
172 the connection. Affected file lib/silcutil/silsockconn.[ch].
173 The checking for disabled socket is checked in the low level
174 silc_socket_write and silc_socket_read functions.
176 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Allow only nicknames and channel names that fits into the
179 7-bit unsigned char ASCII set. Affected file silcd/command.c.
181 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
183 * When processing JOIN command reply in server check that if
184 the channel exists in our global list we'll move it the local
185 list. Affected file silcd/command_reply.c.
187 * Fixed the check whether client is joined on the channel already
188 in JOIN command. Affected file lib/silcclient/command.c.
190 * Fixed the JOIN command reply to check whether the channel
191 already exists. Affected file lib/silcclient/command_reply.c.
193 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
195 * Added silc_ske_status_string to map the SKE error numbers
196 to readable strings. The affected files are
197 lib/silcske/silcske[_status].[ch].
199 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
201 * Do not show the private channels on the WHOIS channel list
202 as it is not allowed by the protocol. The affected file is
205 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
207 * Assure that the packet length digged from the actual packet
208 is something sensible in the silc_packet_decrypt_rest_special
209 in lib/silccrypt/silcpacket.c.
211 * Free and NULL the allocated pointer in silc_hmac_alloc if
212 the HMAC allocation fails. The affected file is
213 lib/silccrypt/silchmac.c.
215 * Print the selected security properties to the log files in
216 the server. Affected file silcd/protocol.c.
218 * Add SKE's reference counter even if calling the completion
219 callback manually. Otherwise it goes negative, although it
220 does not cause any problems. The affected file is
221 lib/silcske/silcske.c.
223 * Remove the client entry with short timeout after giving the
224 KILL command. Affected file lib/silcclient/command.c.
226 * Fixed to send error reply in WHOIS and IDENTIFY commands in
227 case all found clients are already disconnected (WHOWAS would
228 found them) in the server. Affected file silcd/command.c.
230 * Update the last_receive (time of last data received) to be
231 updated only when received private or channel message so that
232 the idle time showed in WHOIS makes more sense.
234 * Added boolean field `valid' in to the SilcClientEntry in the
235 client library to indicate whether the entry is valid or not.
236 This fixes the nickname change bug on channel when changing
237 the nickname to be same than the old (like nick to Nick) the
238 nickname formatter doesn't set the new nick anymore to Nick@host.
239 Affected file lib/silcclient/idlist.[ch].
241 * Now actually fixed the nickname changing on disconnection.
242 Added new function silc_change_nick to the Irssi SILC Client.
243 Affected file irssi/src/silc/core/client_ops.c,
244 irssi/src/silc/core/silc-nicklist.[ch].
246 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Check that the public key exists in the GETKEY command before
249 trying to encode it. Affected file silcd/command.c.
251 * Print some notifications on received public keys with GETKEY
252 command in the Irssi SILC Client. Affected files are
253 irssi/src/fe-common/silc/module-formats.[ch],
254 irssi/src/silc/core/client_ops.c.
256 * Use IDENTIFY command to resolve the server information in the
257 GETKEY command instead of INFO command. Affected file
258 lib/silcclient/command.c.
260 * All command reply functions in the client library now calls
261 the pending command reply callbacks even if an error has
262 occurred. The server has done this a long time and now it was
263 time to move the client library to this as well. Now all
264 errors can be delivered back to the pending command reply
265 callbacks if necessary. Affected files are
266 lib/silcclient/command[_reply].[ch].
268 * Change the nickname on disconnection back to the username
269 because in reconnect the server will enforce it to it anyway.
270 Affected file irssi/src/silc/core/silc-servers.c.
272 * Fixed a config file parsing bug in the Irssi SILC client.
273 Affected file irssi/src/silc/core/clientconfig.c.
275 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * When printing the channel mode on JOIN, verify that the
278 channel key and channel's HMAC are valid. Affected file
279 irssi/src/silc/core/client_ops.c.
281 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
283 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
284 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
285 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
287 * Removed channel key rekey task deleting from the function
288 silc_server_save_channel_key. Affected file silcd/server.c.
289 Added explicit timeout task context instead that is used to
290 delete the task if we are registering a new task before the
291 new task has elapsed.
293 * When channel key rekey occurs the client library now saves
294 the old channel key for a short period of time (10 seconds) and
295 is able to use it in case some is still sending channel
296 messages encrypted with the old key after the rekey. Affected
297 file lib/silcclient/[idlist.h|client_channel.c].
299 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
301 * Added check to the silc_server_new_id_real to not accept
302 new ID if it is the sender's own ID. Affected file is
303 silcd/packet_receive.c.
305 * Assure that we do not announce ourself or the one we've
306 sending our announcements when we're router and are announcing
307 servers to our primary router. Affected file silcd/server.c.
309 * Fixed silc_server_command_identify_check_client to assemble
310 correct WHOIS packet. It send corrupted WHOIS packet and
311 caused problem with router to router connections. Affected
312 file silcd/command.c.
314 Fixed also silc_server_command_whois_check the same way
315 as for the IDENTIFY command.
317 * Added new SilcIDListStatus to the server in the SilcIDListData
318 structure. The status now includes the current status of
319 the entry (like registered, resolved etc.). Affected file
320 silcd/idlist.[ch]. Defined a bunch of different status types
321 as well. This replaced the old boolean registered field as well.
323 Added resolve_cmd_ident field to the SilcClientEntry structure
324 too so that if the entry is for example being resolved so
325 another command may attach to the same pending command reply
326 without requiring to resolve the same entry again. This concept
327 should optimize the WHOIS and the IDENTIFY resolving under
328 heavy load by taking away unnecessary resolving for entries
329 that are being resolved already.
331 Added support for adding multiple pending commands for one
332 command idenfier. Affected file silcd/command[_reply].[ch].
334 * Fixed WHOIS and IDENTIFY save to remove the cache entry
335 before deleting the data. Otherwise the hash table will have
336 freed data in comparison functions. Affected file is
337 silcd/command_reply.c.
339 * Fixed silc_idlist_replace_client_id to add the new entry to
340 the cache with NULL nickname. Otherwise there will be invalid
341 memory as the nickname after the nickname is freed. Affected
342 file silcd/packet_receive.c.
344 * Fixed the silc_idlist_get_clients_by_hash. The entries was
345 saved into wrong slots because the previous number of entries
346 was not taken into account. Affected file silcd/idlist.c.
347 Fixed same thing in silc_idlist_get_clients_by_nickname too.
349 * If we are router and we receive JOIN notify to a channel that
350 does not have any users then notified client is marked as the
351 channel founder, as it is it. The affected file is
352 silcd/packet_receive.c
354 * Added to the extended hash table API's table_del_*ext functions
355 the destructor as argument too, so that the caller can decide
356 which destructor to use or whether to use destructor at all.
357 Affected file lib/silcutil/silchashtable.[ch].
359 * Fixed ID Cache purging. It actually deleted the entries from
360 the hash table after the data was freed. The hash table ended
361 up comparing freed memory. The affected file is
362 lib/silccore/silcidcache.c.
364 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Fixed Irssi SILC client's KILL command's HELP syntax.
368 * The USERS command now resolves the detailed user information
369 if the userinfo field is missing. Affected file is
370 lib/silcclient/command_reply.c.
372 * Do not print error in silc_file_read if the read file does
373 not exist. Just silently return NULL. Affected file is
374 lib/silcutil/silcutil.c.
376 * Fixed the silc_log_output to not wine about NULL filename
377 and to not create some bogus " " filename. Affected file is
378 lib/silcutil/silclog.c.
380 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
382 * Fixed various printing bugs on the user interface in the
383 Irssi SILC Client. Minor changes that were forgotten from
386 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Fixed the configure.in.pre and the compilation and distribution
389 environment to support the new autoconf 2.52. That version is
390 now required to compile the CVS trunk.
392 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
394 * Renamed function silc_parse_nickname to silc_parse_userfqdn
395 to generally parse user@fqdn format strings. Affected file
396 lib/silcutil/silcutil.c.
398 * Added nickname_format and nickname_force_format fields to the
399 SilcClientParams structure. The first one defines the format
400 for the nicknames that the library will enforce if the receives
401 multiple same nicknames. The second one is boolean value and
402 can be used to force the library to always enforce the format
403 to the nicknames regardles whether there are multiple nicknames
404 or not. This configurable formatting was employed to flexibly
405 support accessing multiple nicknames from the user interface.
406 The userinterface can now set the nicknames to what ever format
407 they prefer. Affected file lib/silcclient/silcapi.h.
409 Added function silc_client_nickname_format to the file
410 lib/silcclient/idlist.c. It performs the nickname formatting.
412 Added new field `hostname´ to the SilcClientEntry context.
413 It holds the hostname of the client. Affected file is
414 lib/silcclient/idlist.h.
416 * Irssi SILC Client sets the nicknames in nick@hostn format.
417 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
418 irssi/src/silc/core/silc-core.c.
420 The WHOIS printing now also shows both the real nickname and
421 the formatted nickname so that user knows how to access the
422 user if there are multiple same nicknames cached. Affected
423 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
424 printing formatting too to take the hostname now as a separate
425 argument. The Affected file is
426 irssi/src/fe-common/silc/modules-formats.[ch].
428 * Changed the silc_client_get_clients_local to accept the formatted
429 nickname as argument. It accepts the real nickname too but the
430 formatted nickname can be used to find the true entry from
431 multiple entries. Affected file lib/silcclient/silcapi.h and
432 lib/silcclient/idlist.c.
434 * Added nickname_format_parse field to the SilcClientParams.
435 It is a callback function provided by the application to parse
436 the nickname out of the formatted nickname string. The library
437 calls it to get the nickname from the formatted string. Since
438 the application generally knows better the format of the nickname
439 string it parses it instead of the library, even though library
440 encodes the formatted string. If the callback function is not
441 provided then the library will use the string as is. The
442 affected file is lib/silcclient/silcapi.h.
444 * All the nickname strings passed to the client library in
445 commands are now expected to be formatted nickname strings.
446 If the command does not support the formatted nickname string
447 it will assume that the sent string is the actual nickname.
448 Affected file lib/silcclient/command.c.
450 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Added public key authentication support to OPER and SILCOPER
453 commands in the client library. Affected file is
454 lib/silcclient/command.c.
456 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Changed the get_auth_methdod client operation to be asynchronous.
459 It can be async if the application resolves the authentication
460 method from the server during the negotiation. Added new
461 SilcGetAuthMeth completion callback that the application will
462 call after resolving the authentication method.
464 Added function silc_client_request_authentication_method that
465 the application can use to resolve the authentication method
466 from the server. Added also SilcConnectionAuthRequest callback
467 that the library will call after the server has replied. The
468 application can call this function if it does not know the
469 current authentication method.
471 Affected files are lib/silcclient/client.c and
472 lib/silcclient/silcapi.h.
474 * The Irssi SILC client now automatically resolves the authentication
475 method incase any configuration information is not present (and
476 currently there never is). The affected file is
477 irssi/src/silc/core/client_ops.c.
479 * Fixed public key authentication from the client library.
480 Affected file lib/silcclient/protocol.c. Changed also the
481 protocol specification about the public key authentication in
482 the connection authentication protocol. The actual data to be
483 signed is now computed with a hash function before signing.
485 * Fixed the public key authentication from the server as well.
486 Affected file silcd/protocol.c.
488 * Removed the mlock()'s from the memory allocation routines.
489 Affected file lib/silcutil/silcmemory.c. The ./configure does
490 not check anymore for the mlock(). Affected file is
493 * Fixed USERS command in server to allow the execution of the
494 command for private and secret channels if the client sending
495 the command is on the channel. Affected file silcd/command.c.
497 * Fixed silc_client_get_clients_local to return the clients
498 count correctly. It could return wrong value. Affected file
499 lib/silcclient/idlist.c.
501 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
503 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
504 types. The assembler optimizations seemed not to like 64-bit
505 data types. The assmebler optimizations thus are now enabled
506 also for BSD systems as opposed to only enable them for Linux.
508 * Do not check for threads at all on BSD systems. Affected
509 file configure.in.pre.
511 * Removed -n and -h options from the Irssi SILC Client since
512 they are not used in silc.
514 * Fixed the prime generation to assure that the first digit
515 of the generated random number is not zero since our conversion
516 routines does not like number strings that starts with zero
517 digit. If zero digit is seen the random number is regenerated.
518 This caused some corrupted RSA keys when the zero first digit
519 was met. Affected file lib/silcmath/silcprimegen.c.
521 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
523 * Fixed WIN32 configuration in the ./configure script.
524 Fixed to include xti.h on environments that has it.
525 Patches by Carsten Ilchmann and andrew.
527 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Changed the silc_id_create_client_id to be collision
530 resistant. It is now assured that there cannot be created
531 two same client ID's. I suspect that some weird bugs in
532 the server were actually caused by duplicate Client IDs.
533 Affected file silcd/serverid.[ch]. A router receiving
534 new ID now also assures and informs the sending server
535 if the ID caused collision.
537 * Changed the silc_id_create_channel_id to also assure that
538 there are no collisions.
540 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Statement about ignoring the Mutual Authentication flag when
543 performing rekey with PFS was a bit misleading. It is ignored
544 if it was set in the initial negotiation, it cannot be even
545 set in the rekey. Fixed in the ke-auth draft. Started the
546 new versions of the protocol drafts in the doc/.
548 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Fixed a bug in silc_client_command_identify_save when saving
551 new channel information. The channel name was no duplicated
552 and caused crash on exit. Affected file is
553 lib/silcclient/command_reply.c.
555 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Fixed the getkey command handling in the server. Send just
558 empty OK reply to the sender if the key could not be fetched
559 (but everything else was ok, like the key just was not available).
560 Changed the public key parameter to optional in the protocol
561 specs so that empty OK reply can be sent. Affected file
564 Added a message to Irssi SILC client to tell to user if the
565 server did not return a public key.
567 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Fixed a channel key regeneration bug. It registered new
570 timeout tasks exponentially until all system resources were
571 used. Affected file silcd/server.c.
573 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
575 * Added the SILC Document generator to the scripts/silcdoc.
576 It can be used to generate the Toolkit Reference Manual out
577 of the source tree. Internally it will also use the RoboDoc
578 generator now imported in util/robodoc.
580 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
582 * Added couple of return's in rekey protocol if error orccurred
583 during the protocol. The execution must be terminated.
584 Affected file silcd/protocol.c. Also, terminate the protocol
587 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
589 * The client's Client ID was created initally from the wrong
590 nickname (it could have been in format nick@host) in the
591 silc_server_new_client. Affected file silcd/packet_receive.c
593 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

596 if client could not be added to ID cache. Affected files
597 silcd/packet_receive.c and silcd/server.c.
599 * When client's sock->user_data is freed, NULL also the
600 client->router and client->connection pointers. Added check
601 for these pointers being NULL to various places around the
602 code. Affected file silcd/server.c.
604 * Added client->data.registered == TRUE checks to various
605 places around the code to assure that unregistered client's
606 are not handled when it is not allowed. Affected file
609 * Added `bool registered' fields to all
610 silc_idlist_[server|client]_get_* routines to indicate whether
611 the fetched client needs to be registered or not. Affected
612 file silcd/idlist.[ch].
614 * Add your own entry as registered to the ID cache in the
615 server. Affected file server.c.
617 * Fixed a bug in silc_server_new_server. The SilcServer was
618 set as the new server's context instead of SilcServerEntry.
619 This naturally caused some weird bugs.
621 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
623 * Do not delete the channel rekey task when adding it
624 for in silc_server_create_channel_key.
626 * Changed the silc_server_create_channel_key to return
627 TRUE or FALSE to indicate the success of the channel key
630 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Fixed MSVC++ project files and added missing files to
633 Makefiles under win32/.
635 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Do not add TCP_NODELAY flag if the operating system
638 does not have it defined. Affected files are
639 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
641 * Fixed buffer overflow from Irssi SILC Client. Affected
642 file irssi/src/fe-common/core/themes.c.
644 * Fixed double free in client library in the file
645 lib/silcclient/client.c when disconnecting from server.
647 * Applied double free patch from cras to Irssi SILC client.
648 Affected files irssi/src/core/[modules/expandos].c
650 * Fixed the disconnection handling to Irssi SILC Client.
651 The application must call silc_client_close_connection
652 in ops->connect client operation in case of failure of
653 the connection. Affected file is
654 irssi/src/silc/core/client_ops.c.
656 * Do not set sock->protocol to NULL in the function
657 silc_client_close_connection after executing the protocol's
658 final callback since the sock might not be valid anymore.
659 Affected file lib/silcclient/client.c.
661 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
663 * Do not enable SILC_THREADS if the linking with libpthread
664 did not happen. Affected file configure.in.pre.
666 * Added notion to protocol specification that server must
667 verify the sent authentication payload with CMODE when
668 setting the channel founder key. Implemented it to the
669 server. Affected file silcd/command.c.
671 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
673 * Added _EXTRA_DIST SILC distribution variable to the
674 distributions file. It is used to conditionally add extra
675 files or directories to the specific distribution. Affected
676 files ./prepare, Makefile.am.pre and distributions.
678 Removed the `_' from the start of the distribution names.
681 * Added README.WIN32 for instructions to compile the Toolkit
684 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Fixed a double free in disconnection in the server. Affected
687 file is silcd/server.c.
689 * Fixed the lib/silcske/groups.c to work now also with GMP
690 MP library. The string conversion did not work when using
691 specific base and the base is indicated in the string as well.
693 * Created win32/ directory which now includes MSVC++ specific
694 stuff so that toolkit (DLLs) may be compiled with MSVC++.
695 It will appear only in the toolkit distribution
697 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
699 * Changed the key material distribution function in case when
700 the hash output is too short. The data is now concatenated
701 a bit differently than it used to. Made the change to the
702 SKE protocol specification.
704 * Added better GMP detection to configure.in.pre. A patch
707 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
709 * Fixed a minor bug in SKE that might cause some problem on
710 some platforms. Affected file lib/silcske/silcske.c.
712 * Added the cookie checking for initiator in the SKE. It checks
713 that the responder returns the sent cookie unmodified. The
714 affected file is lib/silcske/silcske.c. Added new SKE
715 error type INVALID_COOKIE that can be sent during the
716 negotiation. Fixed some memory leaks as well.
718 * Added the "invalid cookie" error message to Irssi SILC client's
721 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
723 * Added `task_max' field to the SilcClientParams to indicate
724 the maximum tasks the scheduler can handle. If set to zero,
725 default values are used. Affected file lib/silcclient/silcapi.h.
727 * Fixed memory leaks in silc_client_close_connection. Affected
728 file lib/silcclient/client.c.
730 * Added silc_client_del_client_entry to client library to free
731 all memory of given client entry. Affected file is
732 lib/silcclient/idlist.[ch].
734 * Added new functions silc_client_del_channel and
735 silc_client_del_server to delete channel and server entries.
736 Affected file lib/silcclient/[silcapi.h/idlist.c].
738 * Removed silc_client_del_client_by_id from silcapi.h.
740 * Fixed the INFO command to return the server's own info
741 correctly when querying by Server ID. Affected file is
744 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Removed the non-blocking settings in WIN32 code in the
747 silc_sock_[read/write] and added SleepEx instead. Affected
748 file lib/silcutil/win32/silcwin32sockconn.c. The availability
749 of input data is now checked with FIONREAD and ioctlsocket.
751 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Call silc_schedule_task_del_by_context in the
754 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
755 Affected file lib/silccore/silcprotocol.c.
757 * Call silc_protocol_cancel for active protocols in the
758 silc_server_close_connection if the funtion
759 silc_server_free_sock_user_data has not been called.
760 Affected file silcd/server.c.
762 * Generic tasks cannot be deleted using the del_by_fd
763 task deleting function since generic tasks does not match
764 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
766 * Added a notion to SILCOPER help file that the SILCOPER works
767 only on router server, not on normal server.
769 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Added for WIN32 support for the new scheduler as well.
772 Affected file lib/silcutil/win32/silcwin32schedule.c.
774 * Fixed the SHA1 implementation to work on various platforms.
776 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
778 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
779 API. It is part of the scheduler now. Everything else is
780 as previously but some functions has changed their names.
781 Checkout the lib/silcutil/silcschedule.h for the interface.
782 Updated all applications to use the new interface. Affected
783 files are lib/silcutil/silcschedule.[ch].
785 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
787 * Found a bug in the SKE implementation. The HASH value,
788 specified by the protocol, was not computed correctly. The
789 public key of the responder was not added to the computation
790 even though it is mandatory. Affected file lib/silcske/silcske.c.
791 This unfortunately causes incompatibilities with older
794 * Added WIN32 specific network init and uninit functions:
795 silc_net_win32_init and silc_net_win32_uninit to init and uninit
796 the Winsock2. Affected file lib/silcutil/silcnet.h and
797 lib/silcutil/win32/silcwin32net.c.
799 * Set the socket always to nonblocking mode on WIN32 after
800 reading data or writing data. Affected file is
801 lib/silcutil/win32/silcwin32sockconn.c.
803 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Fixed various compilation problems under WIN32. Affected
806 files lib/silcutil/win32/silcwin32thread.c and
807 lib/silcutil/win32/silcwin32schedule.c.
809 * Removed all _internal.h #includes from public header
810 files. Internal headers must never be included from
813 Removed also the lib/silcske/payload_internal.h file.
815 * All include files that may be needed (public and some others
816 included by the public headers) by application developers are
817 now copied to the ./includes directory. It does not copy any
818 internal headers. Affected file Makefile.defines.pre and all
819 Makefile.am's under lib/ and subdirs.
821 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
823 * Do not change the ~/.silc directory's permissions automatically.
824 Affected file irssi/src/silc/core/clientutil.c.
826 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Do not cancel the protocol in silc_server_close_connection
829 it might cause recursion. Now cancelled in the function
830 silc_server_free_sock_user_data. Affected file silcd/server.c.
832 * Fixed the silc_server_remove_clients_by_server to regenerate
833 the channel keys correctly finally. Added also new function
834 silc_server_remove_clients_channels to actually do it.
835 Affected file silcd/server.c.
837 * Fixed the silc_server_new_channel to not crash by giving
838 wrong router to the new channel. Affected file is
839 silcd/packet_receive.c.
841 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
844 which is given as argument to the silc_client_alloc now.
845 It can be used to configure the client and set various parameters
846 that affect the function of the client.
848 * The USERS command in server did not check whether the channel
849 is private or secret. Affected file silcd/command.c.
851 * Added new argument to the USERS command in protocol specification.
852 The USERS command now can take the channel name as argument
853 as well. Added support for this in client and server and
854 updated the protocol specs.
856 * Completed the GETKEY command in client. It can be now used
857 to fetch also servers public key not only some clients.
858 Affected files lib/silcclient/command[_reply].c.
860 * Added silc_client_get_server to return server entry by the
861 server name. Affected files lib/silcclient/silcapi.h and
864 * Redefined the IDENTIFY command in protocol specification to be
865 more generic. It now can be used to query information about
866 any entity in the SILC Network, including clients, servers and
867 channels. The query may be based either the entity's name
868 or the ID. Added support for this in both client and server.
870 Affected files silcd/command.c and lib/silcclient/command.c
873 * Optimized the WHOIS and WHOWAS commands in the server. Removed
874 the _from_client and _from_server functions. Affected file
877 * Added silc_client_get_channel_by_id_resolve to the file
878 lib/silcclient/silcapi.h to resolve channel information by
879 its ID. Added also silc_client_get_channel_by_id that
880 does not resolve it from the server.
882 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
884 * Added SilcServerEntry context into the client library
885 to represent one server. The INFO command now allocates
886 these to save the resolved server info. For now on the
887 client library will also keep information about servers,
888 connected and resolved with INFO.
890 The INFO command now allocates the SilcServerEntry context
891 and saves the server info there. The COMMAND_REPLY in
892 the INFO now returns the parameters to application in
893 same order as defined in the protocol specification.
895 The entries are cached in the client->server_cache.
897 * The INFO command is now issued after received the Client ID
898 from the server. Affected file lib/silcclient/client.c.
900 * The CMODE_CHANGE notify may now return also an SilcServerEntry
901 to the application as the mode changer might be server.
902 It is guaranteed that NULL is not returned anymore to the
903 application. Affected file lib/silcclient/client_notify.c.
905 The ID Type is now also passed to the application so that
906 it can check whether the returned entry is SilcClientEntry
909 Added new function silc_client_get_server_by_id to return
910 the server entry by ID. Affected files are the
911 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
913 * Do not create the channel in the Irssi SILC Client when issuing
914 the JOIN command but when received the sucessful JOIN command
915 reply. Otherwise the channel might get created even though we
916 could not join it. The Affected file is
917 irssi/src/silc/core/[silc-channels.c/client_ops.c].
919 * Fixed a channel joining bug in router. The router must also
920 check the channel modes, invite and ban lists etc. when serving
921 the JOIN command sent by normal server. Affected file is
922 silcd/command.c. The router now resolves the client's
923 information from the server who sent the JOIN command if it
924 does not know it, and processes the JOIN command only after
927 * Changed the SilcCommandCb to take new argument; void *context2.
928 Affected file lib/silccore/silccommand.h
930 The second argument in the command callbacks in the server now
931 includes the SilcServerCommandReplyContext if the command was
932 called as pending command callback from the command reply.
933 Otherwise it is NULL. When called as pending the status of the
934 command reply will be checked and if it was erronous the
935 error will be sent to the original sender of the command.
936 This way the client always receives the error messages even
937 though the server was actually the one who received the error
938 when it resent the command to router, for example. Affected
939 files silcd/command[_reply].[ch].
941 * Fixed sending WHOWAS command's error message to client if
942 the requested client could not be found. It was missing.
945 * Changed the CMODE and CUMODE commands reply arguments in the
946 protocol specification. The Channel ID is now sent in both
947 of the commands to identify the channel. Implemented this
948 new feature to the client and server. Affected files
949 lib/silcclient/command_reply.c and silcd/command.c.
951 * Made better checks for invite and ban lists in the JOIN
952 command in server. Affected file silcd/command.c.
954 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
956 * The server now performs the incoming host IP/DNS lookup
957 using the silc_socket_host_lookup and thus does not block
958 the server anymore. Affected file silcd/server.c.
960 * Completed the multi-thread support for SILC Scheduler in
961 the lib/silcutil/silcschedule.c.
963 * Fixed the configure.in.pre to detect the pthread correctly
966 * Fixed a deadlock in silc_task_queue_wakeup in the file
967 lib/silcutil/silctask.c.
969 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Added new function silc_schedule_wakeup that is used in
972 multi-threaded environment to wakeup the main thread's
973 schduler. It needs to be used when a thread adds a new task
974 or removes a task from task queues. After waking up, the
975 scheduler will detect the task queue changes. If threads
976 support is not compiled in this function has no effect.
977 Implemented the wakeup mechanism to both Unix and WIN32
978 systems. Affected files are lib/silcutil/silcschedule.[ch],
979 lib/silcutil/unix/silcunixschedule.c and the
980 lib/silcutil/win32/silcwin32schedule.c.
982 * Added new function silc_task_queue_wakeup to wakeup the
983 scheduler by the specified task queue. Affected file
984 lib/silcutil/silctask.[ch].
986 * The silc_socket_host_lookup_start now wakes up the scheduler
987 after adding the timeout task. Affected file is
988 lib/silcutil/silcsockconn.c.
990 * The silc_socket_host_lookup is synchronous now if the threads
991 support is not compiled in. However, the callback is still
992 called asyncronously through the scheduler, anyway. Affected
993 file lib/silcutil/silcsockconn.c.
995 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
997 * Added new function silc_socket_host_lookup to perform
998 asynchronous IP and FQDN lookups for the socket connection.
999 Affected files lib/silcutil/silcsockconn.[ch].
1001 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1004 that may or may not compile the mutex support in.
1006 Changed the silc_mutex_alloc interface. It allocates the
1007 mutex now to the sent pointer and returns TRUE or FALSE.
1009 Affected file lib/silcutil/silcmutex.h.
1011 * Wrote the SILC Task Queue interface to support multi-threads.
1012 Affected file lib/silcutil/silctask.[ch].
1014 * Wrote the SILC Scheduler to support multi-threads. Affected
1015 file lib/silcutil/silcschedule.c.
1017 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1020 in lib/silcutil/win32/.
1022 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Defined SILC Mutex API and SILC Thread API and implemented
1025 them for Unix. Affected files are
1026 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1027 lib/silcutil/unix/silcunixmutex.c and
1028 lib/silcutil/unix/silcunixthread.c.
1030 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * Fixed the silc_server_remove_clients_by_server's channel
1033 key re-generation. The hash table handling was incorrect
1034 and would not work with many channels. Affected file is
1037 * Fixed some memory leaks around the server code.
1039 * Rewrote the silc_server_get_users_on_channel to support IPv6
1040 based Client ID's. Affected file silcd/server.c.
1042 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1043 specification. However, a separate document must be written
1044 to define the detailed signing procedure and the payload
1045 associated with the flag. Defined the flag to the
1046 lib/silccore/silcchannel.h as well.
1048 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Changed the dynamic tables to static size tables in the
1051 lib/silccrypt/silchmac.c.
1053 * Removed GCC dependencies from the code. A patch by cras.
1055 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1057 * Do not show the error "Error receiving packet bla bla"
1058 in server if it really was not an error (-2 means that reading
1059 is pending). Affected file silcd/server.c.
1061 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * Fixed a possible crash in silc_server_remove_clients_by_server
1064 in silcd/server.c. Fixed there also some memory leaks.
1066 * Fixed the silc_idlist_replace_client_id. It could replace
1067 wrong key in the hash table. Affected file silcd/idlist.c.
1069 * Do not check whether there are global users on the channel
1070 if the channel->global_users is FALSE. Affected functions
1071 silc_server_remove_from_one_channel and
1072 silc_server_remove_from_channels in silcd/server.c. Also,
1073 do not check if the removed client is local as we can be
1074 sure that global client was not removed from the channel
1075 and checking for global users is not needed.
1077 * The silc_server_remove_clients_by_server now re-generates
1078 the channel keys correctly for those channels that had
1079 clients removed from them. Affected file silcd/server.c.
1081 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * Found the reason of random crashes in the server. We weren't
1084 ignoring the SIGPIPE signal (which can be sent in write())
1085 and it crashed the server. Affected file silcd/silcd.c.
1087 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Assure that sock->user_data is not NULL in the function
1090 silc_server_packet_send in silcd/packet_send.c.
1092 * Disconnect the remote connection if it could not be added
1093 to any ID lists in the server. The affected file is
1096 * Check in silc_server_packet_send[_real/dest] that the
1097 socket is not disconnecting and ignore the data if it is.
1098 Affected file silcd/packet_send.c.
1100 * Define inline to __inline on native WIN32 compilation.
1101 Affected file includes/silcwin32.h.
1103 * Added some explicit type casts for inline code since MSVC
1104 require them. Affected files lib/silcutil/silcbuffer.h,
1105 lib/trq/silcdlist.h and lib/trq/silclist.h.
1107 * Print warning in log files from now on if the packet
1108 decryption fails. Affected file silcd/server.c.
1110 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Changed the `say' client operation's interface to accept
1113 new `type' argument to indicate the type of the message sent
1114 by the library. The application may filter the library's
1115 messages according the type. The affected file is the
1116 lib/silcclient/silcapi.h.
1118 * Added two new functions to lib/silcclient/silcapi.h:
1119 silc_client_del_client and silc_client_del_client_by_id.
1120 Affected file lib/silcclient/idlist.c.
1122 * Moved the clientincludes.h from includes/ to silc/ and
1123 serverincludes.h from includes/ to silcd/.
1125 * The modes for the CMODE and CUMODE are now passed as
1126 uint32 for application with COMMAND_REPLY. The affected
1127 file is lib/silcclient/command_reply.c.
1129 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * /WHOIS without arguments shows client's own information.
1132 Affected file lib/silcclient/command.c.
1134 * Changed PING to not accept any arguments. The specs
1135 says that client can ping only the connected server so
1136 requiring an argument is not needed. Affected file is
1137 lib/silcclient/command.c.
1139 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Fixed a fatal bug in private message sending and reception
1142 encryption and decryption when using private message keys.
1143 The implementation was incorrect and did not follow the
1144 specification. It causd that some of the message were
1145 lost since it did not use the sending and receiving keys
1146 as the protocol suggests. This has been fixed and will cause
1147 incompatibilities with older clients when sending private
1148 message encrypted with private message keys. Affected files
1149 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1150 and various other in Irssi SILC Client.
1152 Added `responder' boolean argument to the functions
1153 silc_client_add_private_message_key[_ske] to indicate when
1154 the key is added as responder or initiator of the key
1157 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1159 * Removed the silc_ske_check_version function and created
1160 a SilcSKECheckVersion callback. Added also a function
1161 silc_ske_set_callbacks that is now used to set all SKE
1162 callbacks. The callback functions are not given to
1163 the SKE functions anymore, but this function is used to
1166 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1168 * Added `silc_version' argument to the silc_client_alloc
1169 to define the version of the application for the library.
1170 The library will use the version string to compare it
1171 against the remote host's (usually a server) version
1172 string. Affected file lib/silcclient/silcapi.h
1174 * Added the KE protocol context to Key Agreement context
1175 in client library so that we can abort the SKE if it
1176 is in process when we get timeout. Affected file is
1177 lib/silcclient/client_keyagr.c.
1179 * Do not resolve the client ID forever if it returns in the
1180 first time that such client does not exist. This was done
1181 for example with private message. Affected file is
1182 lib/silcclient/client_prvmsg.c.
1184 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1186 * Do not add regex.h for WIN32. The affected file
1187 includes/silcincludes.h.
1189 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1190 not work yet 100%. It generates the DLL's automatically
1191 when compiling with --with-win32 under cygwin.
1193 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1195 * lib/contrib/regex.c is not compiled on WIN32.
1197 * Added silc_net_get_socket_opt function to the
1198 lib/silcutil/silcnet.h.
1200 * Added includes/silcwin32.h for WIN32 specific includes
1203 * Do not use ptime structure or any of the posix process
1204 functions on WIN32 in lib/silccrypt/silrng.c.
1206 * Added silc_gettimeofday to provide generic function
1207 for struct timeval on all platforms. Added the function
1208 to lib/silcutil/silcutil.h.
1210 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1213 library as they clearly belong there. As a plus side we
1214 can make the actual socket connection routines platform
1217 Added also new generic function silc_socket_read and
1218 silc_socket_write (that used to be silc_packet_[read/write].
1219 The implementation of these are platform specific.
1221 * Added WIN32 specific routines of silc_socket_[read/write]
1222 to lib/silcutil/win32/silcwin32sockconn.c.
1224 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Added preliminary support for native WIN32 compilation under
1227 cygwin (using the -mno-cygwin option for GCC) to the
1228 ./configure.in.pre. The --with-win32 now prepares the
1229 compilation for native WIN32.
1231 * Rewrote the SILC Scheduler interface in the file
1232 lib/silcutil/silcschedule.h. The scheduler is now context
1233 based and does not have anymore any global static scheduler.
1234 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1235 and created lib/silcutil/win32 directory for WIN32 based
1238 * Added Unix specific network routines to the
1239 lib/silcutil/unix/silcunixnet.c and the old
1240 lib/silcutil/silcnet.c includes now only generic routines.
1242 Added WIN32 specific network routines to the
1243 lib/silcutil/win32/silcwin32net.c.
1245 * Added Unix specific utility functions from the
1246 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1248 * Added WIN32 SILC Scheduler to the file
1249 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1252 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1254 * Do not handle JOIN notify in the server if the target client
1255 is not registered (idata->registered == FALSE). The affected
1256 file is silcd/packet_receive.c.
1258 * Update the nickrec->founder in event_cumode in the Irssi SILC
1259 client. Affected file irssi/src/silc/core/silc-channels.c.
1261 * Fixed the CUMODE_CHANGE notify handling in the server when
1262 server and router are announcing their clients on channels.
1263 Now the mode changes are saved and notified correctly. The
1264 affected file is /silcd/packet_receive.c.
1266 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1267 They really did not replace the cache entry in the ID Cache.
1268 Now they do that. Affected file silcd/idlist.c.
1270 * Fixed the KICK notify handling in the Irssi SILC client to
1271 update the channel records so that the kicked client does not
1272 appear to be on the channel. The affected file is
1273 irssi/src/silc/core/silc-channels.c.
1275 * Always update the conn->current_channel when executing command
1276 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1278 * Fixed the KILL notify handling in Irssi SILC client to remove
1279 the killed client on all channels.
1281 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Fixed the silc_parse_command_line to remove extra spaces
1284 from the start and end of the arguments. Affected file is
1285 lib/silcutil/silcutil.c.
1287 * Cancel and free any active protocol in the function
1288 silc_server_close_connection. Affected file silcd/server.c.
1290 * Cancel and free any active protocol in the function
1291 silc_client_close_connction. Affected file is
1292 lib/silcclient/client.c.
1294 * Do not execute the KILL command for clients that are in
1295 history (ie. they are not in the network). Affected file is
1298 * Fixed KILL notify handling, client does not crash anymore.
1299 Affected file irssi/src/silc/core/silc-channels.c.
1301 * Reduced the default packet buffer size from 2048 to 1024 in
1302 lib/silccore/silcpacket.c.
1304 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1305 counter to the SKE context that is incresed when the SKE library
1306 performs async operation outside the library. If the outside
1307 process frees the SKE context and FREED status will be set
1308 and the library will detect after the sync operation that the
1309 libary is freed. The affected files are
1310 lib/silcske/silcske[_status].[ch].
1312 * Resolve the client entry information in the function
1313 silc_client_channel_message to assure that NULL pointer is not
1314 passed as client entry to the application. */
1316 * Fixed the task timeout calculation to assure that there is
1317 never negative timeouts. The affected file is
1318 lib/silcutil/silcschedule.c.
1320 * Fixed the channel user mode notification sending in server.
1321 It was sent point-to-point to the router (or to server by router)
1322 but it needs to be destined to a channel. The routines now
1323 supports sending the channel user mode notifys to the channels
1324 when announcing clients and channels. Affected files are
1325 silcd/server.c and silcd/packet_receive.c.
1327 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1328 It did not actually replace the old channel entry in the cache.
1329 Affected file lib/silcclient/client_notify.c.
1331 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1333 * Fixed a possible crash in silc_packet_send_prepare. It now
1334 assures always that there is enough space in the buffer and
1335 at the tail area of the buffer (for MAC).
1337 Fixed the inbound buffer reallocation in silc_packet_read.
1338 It was old code and did not handle the reallocation correctly.
1341 The affected file is lib/silccore/silcpacket.c.
1343 * Fixed buffer overflow in silc_parse_nickname in the file
1344 lib/silcutil/silcutil.c.
1346 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * make install generates new server keys only if there is not
1351 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1354 Added check that if the NOREPLY is set then we will not send
1355 the away message. This avoids infinite loop of away messages
1356 if both clients are away. The affected file is
1357 lib/silcclient/client_prvmsg.c.
1359 * Fixed client crash if /NICK was given without arguments.
1360 Affected file lib/silcclient/command.c.
1362 * Server does not send the invite list in INVITE command back
1363 to the client if the list was not altered. Added this notion
1364 to the protocol spec as well. Affected file silcd/command.c.
1366 Fixed possible crash in INVITE command by checking the
1367 value of silc_server_get_client_route command.
1369 * Fixed the INVITE notify type handling. The arguments are now
1370 taken in correct order and client does not crash. The affected
1371 file is irssi/src/silc/core/silc-channels.c.
1373 Removed the "Inviting xxx to channel" message from the
1374 client library away and let the application handle it.
1375 Affected file lib/silcclient/command.c. Added that message
1376 to Irssi SILC client's message formats.
1378 * Fixed CMODE command crash in client. It now checks the
1379 amount of arguments correctly and does not crash. The affected
1380 file is lib/silcclient/command.c.
1382 * Do not create new channel automatically in silc_channels_join
1383 but check whether the channel by that name already exists.
1384 Affected file irssi/silc/core/silc-channels.c.
1386 * Do not send the SERVER_SIGNOFF to router if the disconnected
1387 entity was the router. Affected file silcd/server.c.
1389 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1390 SILC client as it was missing from there.
1392 Added the handling of the KICK notify to the Irssi SILC client
1393 as it was missing. Added "you have been kicked" message to
1394 Irssi SILC client's message modules formats.
1396 Added the handing of the KILL notify to the Irssi SILC client
1397 as it was missing. Added the kill message module formats
1400 The affected file is irssi/src/silc/core/silc-channels.c.
1402 * The router did not save the channel mode the server announced.
1403 Affected file silcd/packet_receive.c.
1405 * Fixed a possible crash in INFO command in server. If the
1406 server did not provide the server info it crashed. Affected
1407 file silcd/command.c.
1409 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1411 * Fixed the GETKEY command in the server to check also the
1412 global list. Otherwise the GETKEY would not work correctly
1413 in normal SILC server. Affected file silcd/command.c.
1415 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * Fixed GETKEY crash, it crashed if the command did not succseed.
1419 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1422 is now real and not just an macro interface to GMP.
1424 Removed the entire GMP from the source tree and imported new
1425 NSS MPI library instead. Reason for removing GMP is that it is
1426 extremely large and compiles extremely slow. The NSS MPI
1427 is only a few files and compiles in less than 10 seconds.
1428 The speed is also about the same as GMP. The MPI is imported
1429 to lib/silcmath/mpi.
1431 If the system has GMP installed we will still use the GMP.
1432 If it is not then the NSS MPI will be compiled.
1434 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Merged a long nickname (127 characters long) crash bugfix from
1437 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1439 * Merged a freed memory reference bugfix from Irssi CVS tree.
1440 Affected file irssi/src/core/commands.c.
1442 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Added the server's public key sving and verification to the
1445 server when performing the SKE. This was missing and the
1446 remote server's (or router's) public key was accepted without
1447 checking whether we have it previously or trust it at all.
1448 Affected file silcd/protocol.c.
1450 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1452 * Check in the silc_server_timeout_remote if protocol is active
1453 and make sure that the protocol's final callback is called so
1454 that all memory if freed. Affected file silcd/server.c.
1456 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * silc_server_whois_send_reply crashed the server if the nickname
1459 was 127 characters long. Affected file silcd/command.c.
1461 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Added sanity check to the silc_server_new_client. If the hostname
1464 is provided inside username then check that the provided hostname
1465 really is the same as the resolved one. If the hostname was not
1466 resolved then check it from the public key. Affected file is
1467 silcd/packet_receive.c.
1469 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1470 if the server disconnected us and the connection is not valid
1471 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1473 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1474 the library to the lib/silcutil/silcutil.[ch].
1476 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Close log file after open. Affected file
1479 lib/silcutil/silclog.c.
1481 * Check whether sock == NULL in silc_client_send_packet and return
1482 if it is. Affected file lib/silcclient/silcclient.c.
1484 * Check rec->entry == NULL in the Irssi SILC Client before
1485 sending the channel message. Affecte file is
1486 irssi/src/silc/core/silc-servers.c.
1488 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Merged a splitted window bugfix from Irssi CVS tree. The
1491 affected file is irssi/src/fe-text/textbuffer-view.c.
1493 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1494 It did not print nickname.
1496 * Improved the distributions system a bit.
1498 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1501 irssi/src/fe-text/gui-window.c.
1503 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1504 to in-active server. The affected file is
1505 irssi/src/silc/core/client_ops.c.
1507 * Resolve the client in USERS command reply if the entry does
1508 not have username resolved. The affected file is
1509 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1510 command to WHOIS command to really resolve stuff. The USERS
1511 is not used any more in any critical section so WHOIS can
1512 be used even though it might be slower than IDENTIFY.
1514 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1517 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1519 * Changed the protocol API a bit more consistent in the
1520 lib/silccore/silcprotocol.[ch].
1522 * Changed the following headers to ROBODoc format:
1524 lib/silccore/silcpayload.h
1525 lib/silccore/silcprotocol.h
1526 lib/silccore/silcsockconn.h
1528 All core library headers are now formatted.
1530 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Fixed a bug in Irssi SILC client; do not show that you are
1533 server/router operator if you really are not. Affected file is
1534 irssi/src/silc/core/client_ops.c.
1536 * Renamed silc_command_free_payload to silc_command_payload_free.
1537 Affected file lib/silccore/silccommand.h
1539 * Added silcmath.h to include the prototoypes of various routines
1540 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1543 * Changed the following headers to ROBODoc format:
1545 lib/silccore/silcchannel.h
1546 lib/silccore/silccommand.h
1547 lib/silccore/silcid.h
1548 lib/silccore/silcidcache.h
1549 lib/silccore/silcmode.h
1550 lib/silccore/silcnotify.h
1551 lib/silccore/silcpacket.h
1552 lib/silcmath/silcmath.h
1554 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Added checking to the server code not to start the server if
1557 ciphers and stuff are not configured properly. Affected files
1558 silcd/serverconfig.[h] and silcd/server.c.
1560 * Changed the layout of the header files of the public interfaces
1561 in the SILC libraries. The new layout supports ROBODoc
1562 documentation tool (and some others) so that it is easy to create
1563 a library reference manual. All the other headers and source
1564 code must still follow the CodingStyle document. Also source
1565 code must not include these ROBODoc stuffs, only the headers.
1566 Furthermore, all public interface headers must now be named
1567 by using `silc' prefix, example: silcapi.h, silccipher.h.
1568 Some files were renamed due to this. All the other headers
1569 must not be used as public interfaces. I will update the
1570 CodingStyle document later. Changed following headers, so far:
1572 lib/silcclient/silcapi.h
1573 lib/silccore/silcauth.h
1574 lib/silccore/silcprivate.h
1575 lib/silccrypt/silcdh.h
1577 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Removed silc_client_packet_send_flush from the client library
1582 as it is not needed. Affected file lib/silcclient/client.[ch].
1584 * Added printing of message of unresolved authentication method
1585 to the Irssi SILC client. Added it to the module formats.
1586 Removed the same message from the client library.
1588 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * Added new distribution feature, DISTLABEL. Every distribution
1591 can define own preprocessor label that can be used in the
1592 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1593 file distributions, acconfig.h.pre and prepare.
1595 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * Added Makefile.defines_int to include the actual definitions
1598 for Makefile.defines.in. Tested the new distribution system,
1599 created distributions and tested installation.
1601 * Added AWAY message printing to the Irssi SILC client. Added
1602 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1604 * Added SCONNECT command to call the SILC's CONNECT command.
1605 Cannot use CONNECT directly since Irssi uses that internally.
1606 Affected file irssi/src/silc/core/silc-servers.c.
1608 Added ACTION local command. It is same as ME command but takes
1609 the channel as mandatory argument.
1611 Rewrote some of the Irssi's help files to suite for SILC
1614 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1616 * Added Makefile.defines[.in] that should for now on be included
1617 in all Makefile.am file in the source tree. That file includes
1618 all common compilation definitions for SILC source tree.
1620 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Minor changes to the ./prepare script to change the package
1623 name according the distribution name to the configure.in.
1625 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Created new distribution system. Added file `distributions'
1628 that defines all the distributions that can be created out of
1629 the SILC source tree. The ./prepare script now reads that
1630 file to determine how to prepare the distributions. The
1631 first argument to the ./prepare is the name of the distribution
1632 and second is the version of the distribution. If given
1633 without arguments it creates the default (toolkit) distribution
1634 with the default version (defined in ./prepare).
1636 All Makefile.am files that are subject to the distributions
1637 are now named as Makefile.am.pre. These are ./Makefile.am
1638 and lib/Makefile.am. Others may be changed later.
1640 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Added invite list, ban list, some key management and connection
1643 error message printing to module formats in the Irssi SILC client.
1645 * Added new silc_client_set_away_message to set the away message
1646 that is back to the person who sent private message. The
1647 affected file lib/silcclient/silcapi.h and the
1648 lib/silcclient/client_prvmsg.c.
1650 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Fixed the private message sending in the Irssi SILC client,
1653 added local command KEY to the Irssi SILC client.
1655 Added key management and key agreement message formats to the
1656 irssi/src/fe-common/silc/module-formats.[ch].
1658 Added USERS (alias WHO) printing, server/router operator
1659 indication and LIST command printing to the module formats.
1661 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Fixed channel joining notify handling, cumode notify handling
1664 from Irssi SILC client.
1666 * Added SILC specific module-formats to the Irssi SILC client so
1667 that SILC specific message hilighting, colors etc is possible.
1668 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1670 Added channel mode, channel user mode, actions, notices,
1671 whois and whowas printing to the the module-formats.c.
1673 * Fixed a bug in channel deletion in the server. The channel
1674 is not left to the cache even if the channel founder auth mode
1675 is set when there are no users anymore on the channel. Affected
1676 file silcd/server.c.
1678 * The silc_net_localhost now resolves the entire hostname including
1679 the domain name. Affected file lib/silcutil/silcnet.c.
1681 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Changed the ask_passphrase client operation to be ascynchronous.
1684 It has now a completion callback and a context that the
1685 application must call after it has got the passphrase from
1686 the user. Affected files lib/silcclient/silcapi.h,
1687 lib/silcclient/protocol.c, lib/silcclient/command.c and
1690 Added SilcAskPassphrase callback that the application calls
1691 to deliver the passphrase to the library.
1693 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1694 The public key verification and especially a certificate
1695 verification is asynchronous procedure.
1697 Added new SILC_SKE_STATUS_PENDING status to indicate the
1698 request is pending and a callback will be called to finalize
1701 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1702 indicate that remote end did not send its public key (or
1703 certificate), even though we require it. Added check for this
1704 condition in the SKE. This was a security bug, now fixed.
1706 Defined new SilcSKEVerifyCbCompletion callback that is called
1707 when the verification process is completed.
1709 The affected files lib/silcske/silcske_status.h and
1710 lib/silcske/silcske.[ch].
1712 * Changed the verify_public_key client operation to be async
1713 as well. Defined SilcVerifyPublicKey callback that is used to
1714 indicate the success of the public key verification process.
1716 Changed the server and client to use the new async client
1719 * Changed the Irssi SILC client's internal scheduler to be called
1720 twice as many times as it used to be. As a result the client
1721 should be a bit faster now. Affected file is
1722 irssi/src/silc/core/silc-core.c.
1724 * Added support to Irssi SILC client of asynchronous public key
1725 verification and passphrase inquiry. Affected file is
1726 irssi/src/silc/core/silc-core.c.
1728 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Do not say "You have left channel %s" in client library.
1731 Moved it to the application. Affected files are
1732 lib/silcclient/command.c and silc/client_ops.c.
1734 * Fixed silc_client_get_clients. Command context was not
1735 duplicated and was freed memory in the callback. Affected
1736 file lib/silcclient/idlist.c.
1738 * Do not say "you are now talking..." on JOIN command in the
1739 client library. The appliation must handle it.
1741 * Do not say ".. changed topic to" in command reply in the
1742 client libary. The application must handle it.
1744 * Fixed TOPIC command sending in the client library.
1746 * Fixed a memory leak in silc_client_command_free in the file
1747 lib/silcclient/command.c.
1749 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Imported a modified version of Irssi client to the source tree.
1752 The Irssi will be used to create a new client called
1753 Irssi SILC. Imported to irssi/.
1755 Added silc_core_init_finish function to the Irssi. Affected
1756 file irssi/configure.in.
1758 A lot changes in the Makefile.ams around the irssi tree.
1760 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Do not rehash if the new size is same as the old size of the
1763 hash table, in the silc_hash_table_rehash*. The affected file
1764 lib/silcutil/silchashtable.c.
1766 * Replaced hash_table_del_by_context calls from the server
1767 (when channel->user_list and client->channels) to the
1768 hash_table_del as it is sufficient and faster.
1770 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Added silc_hash_table_list, silc_hash_table_get and the
1773 SilcHashTableList structure to provide an alternative way to
1774 traverse the hash table. The affected files are
1775 lib/silcutil/silchashtable.[ch].
1777 * Changed the server's idlist routines to use the hash table
1778 routines to optimize the code.
1780 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Replaced the client entry's `channel' list and channel entry's
1783 `user_list' list to hash tables for optimized lookup. Changed
1784 the code to use the hash table interface around the code.
1785 Affected file lib/silcd/idlist.[ch].
1787 * Added `auto_rehash' boolean argument to the function
1788 silc_hash_table_alloc to indicate whether the hash table should
1789 auto-rehash when it thinks is appropriate time. It will
1790 increase the hash table size if the there is twice as much
1791 entries in the table than the size of the table, and will
1792 decrease the size if there are twice as less entries than
1793 the size of the table.
1795 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1799 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * silc_idcache_purge_by_context deletes the entry now by context
1802 as it is supposed to do. Affected file lib/silccore/idcache.c.
1804 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1805 client is not anymore valid (WHOWAS givens the info) and not
1806 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1808 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Removed the `data' and `data_len' arguments from the ID Cache
1811 interfaces and added `name' argument. ID Cache does not handle
1812 anymore the binary data only a names associated with given ID.
1814 * When hashing a Client ID with silc_hash_id the entire ID is
1815 not hashed anymore, instead only the hash of the Client ID is
1816 hashed. This way we can access the Client ID from the cache
1817 with Client ID but with the hash of the ID (which is a hash of
1818 the nickname) as well without any difference in performance.
1820 Added also silc_idcache_find_by_id_one_ext to do one on one
1821 searching when we have the actual ID. Added also function
1822 silc_hash_client_id_compare. The affected files are
1823 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1825 * When hashing the name associated with a ID it is always done
1826 in lowercase. This way we can access the cache without worrying
1827 about case-sensitivity, even though, for example nicknames are
1830 * Fixed a bug in server with channel message sending. It put
1831 wrong ID type as destination ID. The affected file
1832 silcd/packet_send.c.
1834 * silc_idcache_del_by_context now deletes from all hash tables
1835 by context. Affected file lib/silccore/idcache.c.
1837 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Changed the client library to use the new ID Cache interface.
1840 Changes around the source tree.
1842 * Added silc_hash_table_rehash_ext to rehash with specific
1843 hash function. Affected file lib/silcutil/silchashtable.[ch].
1845 * Added silc_hash_string_compare to compare two strings in the
1846 hash table. Affected file lib/silcutil/silcutil.[ch].
1848 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Added new function silc_idcache_del_by_context into the
1851 lib/silccore/idcache.[ch].
1853 * Changed the server's ID list routines to use the new ID Cache
1854 interface. Changes around the source tree.
1856 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Added silc_hash_table_del[_by_context]_ext functions in to the
1859 lib/silcutil/silchashtable.[ch].
1861 Removed silc_hash_table_find_all* routines and added new
1862 silc_hash_table_find_foreach to replace them.
1864 Added silc_hash_table_replace_ext function as extended
1865 replacing function. Separated the simple hash table interface
1866 from the extended hash table interface in the file
1867 lib/silcutil/silchashtable.h.
1869 * Fixed minor bugs and changed it to use some of the new
1870 hash table functions in lib/silccore/idcache.c
1872 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Added new function silc_hash_table_find_all to return all keys
1875 in the hash table by the specified key. As the hash table is
1876 collision resistant it also makes it possible to have several
1877 duplicate keys in the hash table. This function may be used to
1878 find all of the keys from the hash.
1880 Added user_context arguments to the SilcHashFunction,
1881 SilcHashCompare and SilcHashDestructor to deliver user specified
1884 Added new fuctions silc_hash_table_find[_all]_ext to do
1885 extended lookup with specified hash and compare functions and
1886 specified user contexts.
1888 Added new function silc_hash_table_add_ext to add the key
1889 with specified hash function and user context.
1891 Added new function silc_hash_table_foreach to traverse all
1892 entrys in the hash table. Added SilcHashForeach callback
1895 Added new function silc_hash_table_del_by_context to delete
1896 the entry only if the context associated with the key matches.
1898 Affected files are lib/silcutil/silchashtable.[ch].
1900 * Removed silc_hash_[server/client/channel]_id and added just
1901 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1902 silc_hash_id_compare to compare two ID's using as the hash table
1903 comparison function. Added also silc_hash_data to hash
1904 binary data and silc_hash_data_compare to compare it.
1906 * Removed silc_idlist_find_client_by_hash as it is not needed
1907 anymore. Affected file silcd/idlist.[ch].
1909 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1910 to use internally the SilcHashTable. The new ID Cache is a lot
1911 faster than the old one. Some of the ID Cache interface was also
1912 rewritten and obsolete and stupid functions were removed.
1914 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Added entry_count field to the SilcHashTable to keep the number
1917 of the entries in the table. Implemented the function
1918 silc_hash_table_rehash. Added new function
1919 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1921 Fixed a minor bug in silc_hash_table_free.
1923 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1924 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1925 into the lib/silcutil/silcutil.[ch].
1927 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Implemented a collision resistant hash table into the
1930 lib/silcutil/silchashtable[ch]. See the header and the source
1931 for the SilcHashTable API.
1933 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Merged dotconf version 1.0.2 into lib/dotconf.
1937 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Do not compile anything in lib/silcsim/* if the SIM support
1940 is not enabled. The tree should now compile without problems
1943 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Compiled the SILC under cygwin. Compiled and tested briefly
1946 without problems. More tests needed. The SIMs didn't compile
1949 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1951 * Fixed possible crash in silc_get_username in the
1952 lib/silcutil/silcutil.c.
1954 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1956 * Fixed a va_arg in silc/client_ops.c.
1958 * Oops, RC5 routines were named AES and caused some problems
1959 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1961 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added new SilcIDIP structure into the lib/silccore/id.h and
1964 replaced the old `ip' fields from all SILC ID's to that type.
1965 This is a step towards IPv6 support.
1967 The silc_id_get_len takes now the ID as an extra argument.
1968 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1969 both IPv4 and IPv6 based ID's.
1971 The affected files are lib/silccore/id.[ch] and other files
1972 around the tree using these routines.
1974 * Removed the ID length arguments in server from various
1975 silc_server_send_notify_* routines -> they are not needed
1978 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Fixed memory leak in silc_encode_pem_file in the file
1981 lib/silcutil/silcutil.c.
1983 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Check minor version as well in the SKE. Affected files are
1986 silcd/protocol.c and lib/silcclient/protocol.c.
1988 * Added --identifier option to the server so that an identifier
1989 can be when creating the public key for the server. Affected
1990 file is silcd/silcd.c.
1992 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1993 lib/silccrypt/silcpkcs.c.
1995 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Register default ciphers and stuff when using -C option with
1998 the server. Affected file sildc/silcd.c.
2000 * Put back the servers public key filename format, it is better
2001 than the new one. For now, the client keys are saved with the
2002 new filename format. The affected file silc/client_ops.c.
2004 * Implemented the Cipher API for the rest of the ciphers that
2005 did not implement it or implemented it the wrong way.
2007 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Register default ciphers and stuff when using the -S option
2010 in the client. Affected file silc/silc.c. Same also when
2011 creating new key pair with -C option.
2013 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Fixed the silc_verify_public_key client operation function to
2016 save the public keys differently. The fingerprint is now
2017 used as filename and not the hostname. This way also the
2018 client keys are saved uniquely and not with hostnames. The
2019 affected file is silc/client_ops.c.
2021 * Trimmed the silc_hash_fingerprint function to remove extra
2022 whitespaces from the end of the fingerprint. The affected
2023 file is lib/silccrypt/silchash.c.
2027 * Added silc_cipher_register_default function to register all
2028 default ciphers. It can be used when configuration files
2029 does not exist and the application does not want any specific
2030 ciphers in any specific order.
2032 The SilcDList is now used as silc_cipher_list dynamically
2033 allocated cipher list. Removed the static list all together
2034 and now all ciphers must be allocated to the dynamic list.
2035 The silc_cipher_alloc routine was changed to check only the
2038 All silc_cipher_* routines that used to return int returns
2041 The affected files lib/silccrypt/silccrypt.[ch].
2043 * The same thing was done to silc_hash_* as for silc_cipher_*
2044 routines. Affected files lib/silccrypt/silchash.[ch].
2046 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2047 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2048 Added also silc_pkcs_[un]register[_default] functions.
2049 Removed the data_context from the PKCS API.
2051 * Added silc_hmac_register_default function to register default
2052 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2053 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2054 to unregister all hmacs at once.
2056 * Register the default ciphers, hash functions, PKCSs and HMACs
2057 if client's configuration file does not exist. The affected
2060 * The client did not load the hash functions from the SIM
2061 modules at all. Added support for this. Affected file is
2062 silc/clientconfig.c.
2064 * When decoding public key with silc_pkcs_public_key_decode, check
2065 the supported algorithm only if PKCS are registered. Affected
2066 file lib/silccrypt/silcpkcs.c. The same was done with the
2067 silc_pkcs_private_key_decode.
2069 * Fixed the SILC List routines to keep the list always in order.
2070 It used to change the list's order when traversing the list but
2071 not it preserves the order. Affected file lib/trq/silclist.h.
2073 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * Added the client library to use the SilcSocketConnection's
2076 reference counter (by silc_socket_dup) to prevent the bug that
2077 the socket object may be freed underneath async operation.
2079 * The name resolv library checking fixes in the configure.in.pre.
2082 * Created new version of the protocol drafts for future
2083 development. The -03 drafts are the ones that will be changed
2084 in the trunk now and the -02 will remain as they are.
2086 * Send list of CUMODE notifys to the router when announcing
2087 the channel users to the router. Affected file silcd/server.c.
2088 If the router receiving channel founder CUMODE for a channel
2089 that already has channel founder it will send CUMODE notify
2090 to the sender to remove the channel founder rights from the
2091 announced client. Affected file silcd/packet_receive.c.
2093 * The CUMODE notify may now use Server ID as well as the entity
2094 who changes the mode. Updated protocool specs.
2096 * Updated INSTALL and README files.
2098 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * New web pages in the http://silc.pspt.fi. The pages was
2105 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Implemented the [DenyConnectin] config section in the server.
2108 Added silc_server_config_denied_conn to check whether incoming
2109 connection is denied. Affected file silcd/serverconfig.[ch].
2111 * Do not check the ports when checking the incoming configuration
2112 data if the port is 0, meaning any. Affected file is
2113 silcd/serverconfig.c.
2115 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Fixed buffer overflow in silc_string_compare in the file
2118 lib/silcutil/silcutil.c.
2120 * Fixed double free in silc_server_command_leave in the file
2123 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Fixed the version checking in the server. Affected file is
2128 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Fixed the configuration data fetching when accepting new
2131 connections in the server. Affected file silcd/server.c.
2133 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Added `sender_entry' argument to the function
2136 silc_server_packet_relay_to_channel so that we can check
2137 whether some destination actually belongs to the same route
2138 the sender belongs (ie, we must not resend the packet to the
2139 sender). Affected file silcd/packet_send.[ch].
2141 * Added `servername' field to the SilcClientEntry in the server
2142 to hold the name of the server where client is from. Affected
2143 file is silcd/idlist.h.
2145 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Moved the channel message encrypting in the router betwen
2148 router connections from silc_server_channel_message to the
2149 silc_server_packet_relay_to_channel since we want to check
2150 whether we have anybody channel before encrypting anything.
2151 Affected files silcd/packet_[receive/send].c.
2153 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Fixed the [AdminConnection] server config section to support
2156 multiple entries. Affected file silcd/serverconfig.c.
2158 * Added support into the server to check the validity of the
2159 incoming connection before executing any KE or authentication
2162 * The connection configuration is now saved to the KE and
2163 connection auth protocol contexts and not fetched anymore in
2164 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2166 * The local hosts listenning address and port is also resolved
2167 now when starting the server. We want to have the socket object
2168 to include the real address and port for the listener. Added
2169 new function silc_net_check_local_by_sock into the files
2170 lib/silcutil/silcnet.[ch].
2172 * Fixed a broadcast bug in server -> do not broadcast if we
2175 * Fixed a routing bug. Do not route broadcast packets ever.
2176 Broadcast packets must be processed always and not routed since
2177 they may be destined to some other host than yourself and thus
2178 would get routed without no good reason. Affected file is
2181 * Added function silc_server_config_is_primary_route to check
2182 whether primary router connection has been configured (a router
2183 configuration that we are initiating). If there is not, we
2184 will assume that there is only two routers in the SILC network
2185 and we will use the incoming router connection as our primary
2186 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2188 * Changed the order of the broadcasting. Broadcast _after_ the
2189 packet has been processed not before. Affected file is
2192 * Fixed a [ClientConnection] parsing bug. The port was never
2193 parsed correctly thus resulting to port 0. Affected file
2194 silcd/serverconfig.c.
2196 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2197 argument and did not set the broadcast packet flag. Affected
2198 file silcd/packet_send.c. Fixed same bug in the function
2199 silc_server_send_notify as well.
2201 * If we receive NEW_ID packet for our own ID in the server, ignore
2204 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Removed the nickname from the Private Message Payload.
2209 Updated the code and the protocol specs.
2211 * Updated protocol specs for submitting to the IETF.
2213 * Tweaked the Random Number Generator a bit. Affected file
2214 lib/silccrypt/silcrng.c. Exported a new function
2215 silc_rng_[global]_add_noise which can be used to add more
2218 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Do not parse packets with different timeout when protocol
2221 is active -> may cause problem with rekey. Affected file
2224 * When server receives signoff notify it must not create
2225 new channel key if the client is on any channels since the
2226 sender of the signoff notify will create it.
2228 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Added printing of error messages during SKE protocol from the
2231 failure packet sent by server during SKE. Affected file
2234 * Removed the client's failure_callback handling with timeout
2235 and handle it immediately when received.
2237 * The SKE library returned wrong type in SUCCESS and FAILURE
2238 packets. They must be 32 bit MSB not 16 bit MSB.
2240 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Ok, rewrote the logic of the re-key and now it seems to work.
2243 I tested it on high traffic with frequent re-keys without
2244 problems. Added hmac_receive (and renamed hmac to hmac_send)
2245 in SilcClientConnection in lib/silcclient/client.h and
2246 in SilcIDListData in silcd/idlist.h. Also, removed the
2247 SilcPacketParserContext's cipher and hmac fields as they are
2248 not needed anymore and actually caused some problems when
2249 the ciphers and hmac's changed underneath the packet parser.
2251 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * If re-key protocol is active then process the incoming packets
2254 synchronously since we must assure that icoming packets encrypted
2255 with the old key is processed before the new keys is set to
2256 use. This is true other packets than for REKEY packets.
2257 Affected file silcd/server.c. The same was done to client library
2258 as well, affected file lib/silcclient/client.c.
2260 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Fixed bug in client and server to accept the force send if
2263 the packet is send from silc_[server/client]_packet_process
2264 function. Otherwise the packets are never delivered, oops.
2266 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Disable force sending of packets when REKEY protocol is active.
2269 We must assure that no packet is sent directly when rekey is
2270 performed. All packets must be sent through packet queue.
2271 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2272 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2273 function is silc_[server/client]_packet_send_real to check
2276 * Replaced the SIM paths from example config files to
2277 /usr/local/modules. Also, make install creates now
2278 /usr/local/silc/logs directory to hold all the SILC server
2281 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Made the configure.in.pre work on Solaris. Patch by salo.
2285 * Made all ciphers compatible with non-x86 machines. Defined
2286 CBC mode macros into lib/silccrypt/ciphers_def.h.
2288 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Fixed the make install.
2292 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * When MAC computation fails the silc_packet_decrypt returned 0
2295 even though it was supposed to return -1. Fixed this. The
2296 affected file is lib/silccore/silcpacket.c.
2298 * Do not replace the config files in /etc/silc (in make install)
2299 if they already exist. Affected file ./Makefile.am.
2301 * Do not send re-key packets immediately but through packet queue.
2302 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2304 * Changed silc_net_check_host_by_sock to return FALSE if the
2305 IP/DNS could not be resolved. Though, it returns the IP address
2306 now even if it could not resolve it (but returns also FALSE).
2307 Affected file lib/silcutil/silcnet.[ch].
2309 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Added silc_pkcs_decode_identifier to decode the public key's
2312 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2313 Added also silc_pkcs_free_identifier. Added also new context
2314 SilcPublicKeyIdentifier.
2316 * Added -S option to the silc client. It is used to dump the
2317 contents of the specified public key file.
2319 * Changed the PKCS api to return the public key length when
2320 setting the public key.
2322 * Fixed a fatal bug in the public and private key file loading.
2323 Affected file lib/silccrypt/silcpkcs.c.
2325 * Execute the packet parsing for client with zero (0) timeout
2326 if the protocol is active. Affected file silcd/server.c.
2328 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Made the key generation options to the silcd program. Added
2331 -C option, equivalent to client's option.
2333 * Added new [ServerKeys] config section to the server. It
2334 configures the server's public and private key.
2336 * Defined generic Public Key Payload into the protocol
2337 specification to send specific type of public keys and
2340 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2341 public key or certificate.
2343 * Implemented the GETKEY command to the server and to the
2344 client library and on user interface.
2346 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Made preliminary `make install' work.
2350 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Added SilcServerRekey context into silcd/idlist.h.
2354 * Added the PFS support as defined in the specification to the
2355 SKE protocol. Affected files lib/silcske/*.c.
2357 * Added `ske_group' field to the SilcServerRekey context to hold
2358 the number of the SKE group that is used with PFS in re-key.
2359 Affected file silcd/idlist.h.
2361 * Added PFS re-key support to the server. Affected file is
2364 * Added silc_protocol_cancel to cancel execution of the next
2365 state of the protocol. Affected file is
2366 lib/silccore/silcprotocol.[ch].
2368 * Added the re-key support with and without PFS to the client
2369 library. Re-key is performed once in an hour, by default.
2371 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2372 Added silc_client_rekey_callback and silc_client_rekey_final.
2373 Affected files are lib/silcclient/protocol.[ch] and
2374 lib/silcclient/client.[ch].
2376 * Removed the `hmac_key' and `hmac_key_len' fields from the
2377 SilcClientConnection structure; not needed. Affected file is
2378 lib/silcclient/client.h.
2382 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Do not ask whether user wants to use the negotiated private key
2385 for private messages, just use it. Affected file is
2386 silc/local_command.c.
2388 * Added `send_enc_key' and `enc_key_len' fields to the
2389 SilcIDListData structure since they are needed in the re-key
2390 phase. Affected file is silcd/idlist.[ch].
2392 * Implemented the simple re-key protocol into the server.
2393 Affected files silcd/server.c and silcd/protocol.[ch]. The
2394 re-key will be performed once in an hour, by default.
2396 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2397 Added silc_server_rekey, silc_server_rekey_callback and
2398 silc_server_rekey_final.
2400 * Removed Tunneled flag from the protocol. Updated the code
2401 and the specifications.
2403 * Adde `pfs' field to the SilcIDListData to indicate whether
2404 the PFS is to be performed in the re-key. Affected file is
2407 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2410 int64 of at least the xintXX size. If void * is less that 4
2411 bytes uint32 * will be used. Defined bool as boolean.
2413 * Changed _ALL_ unsigned long and unsigned int to uint32,
2414 unsgined short to uint16 in the source tree.
2416 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2417 not handle clients that has entry->data.registered == FALSE.
2418 They are not in the network anymore. Affected file is
2421 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Implemented the sending of the SERVER_SIGNOFF notify in the
2424 server. Affected file is silcd/server.c.
2426 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2427 Added also silc_notify_payload_encode_args into the
2428 lib/silccore/silcnotify.[ch].
2430 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2431 Affected file silcd/packet_receive.c.
2433 * Implemented the SERVER_SIGNOFF notify handling in the client
2434 library. Affected file lib/silcclient/client_notify.c. Also,
2435 implemnted the printing of the SERVER_SIGNOFF info to the
2436 application. Affected file silc/client_ops.c.
2438 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2439 if the deleting was successful. Affected file silcd/idlist.[ch].
2441 * Added support for public key authentication in the connection
2442 authentication protocol in the client library. Affected file
2443 lib/silcclient/protocol.c.
2445 * Changed the server's silc_idlist_get_clients_by_* interface
2446 to support already allocated array so that new entries may be
2447 added to pre-allocated array. Affected file silcd/idlist.[ch].
2448 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2449 and command replies.
2451 * All command reply functions in the server now calls the
2452 pending command callback even if error occured. This way the
2453 error will be delivered to the client as well. Affected files
2454 silcd/command.c and silcd/command_reply.c.
2456 * Fixed INFO command to return local server's info if no server
2457 was provided. Affected file lib/silcclient/command.c.
2459 * Removed RESTART command for good. Updated the code and the
2462 * Rewrote parts of the task system. It is a bit simpler now.
2463 Removed unsued task priorities. The affected files are
2464 lib/silcutil/silctask.[ch].
2466 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Moved the USERS printing from the library to the application.
2469 Affected files lib/silcclient/command.c and silc/client_ops.c.
2471 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added channel key re-key support. The re-key is perfomed
2476 only by the router and is done once in an hour. Added `rekey'
2477 field to the SilcChannelEntry in the server. Affected files
2478 silcd/server.c and silcd/idlist.h.
2480 * Added silc_task_unregister_by_context into the file
2481 lib/silcutil/silctask.[ch].
2483 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Added SILC_UMODE_GONE mode to indicate when the client is not
2486 present in the SILC network. Added also support to the local
2487 command AWAY that will set this mode. Added support of showing
2488 "xxx is gone" in WHOIS command. The USERS command shows the
2489 gone status as well.
2491 * Fixed setting server and router operator privileges in the
2492 server's UMODE command. Affected file silcd/command.c.
2494 * Merged the SKE KE1 and KE2 payloads into one payload. The
2495 new KE payload is equivalent to the old KE2 payload.
2497 Cleaned up the SKE Start Payload parsing. It now uses the
2498 simple buffer unformatting to do the parsing. A lot faster
2501 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2502 to the SKE that is used to indicate whether both of the SKE
2503 parties should perform authentication. By default only the
2504 responder performs authentication. By setting this flag also
2505 the initiator must do authentication. By default it is unset
2506 since in normal SKE case, client to server connection, only
2507 the responder should do authentication. When doing SKE between
2508 two clients both should perform authentication. Updated the
2509 code and the protocol specs.
2511 * A little fix to IDENTIFY command in the server. Search the
2512 client first by hash not nickname. Affected file is
2515 * Fixed the silc_client_close_connection to support closing
2516 the client to client connections wihtout deleting too much
2517 data. Affected file lib/silcclient/client.c.
2519 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2520 are received if protocol used to be active but is not anymore
2521 the application would crash due to NULL pointer dereference.
2522 Affected files silcd/server.c and lib/silcclient/client.c.
2524 * Added `hash' field to the SilcClientConnection to include
2525 the hash function negotiated in the SKE protocol.
2527 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2528 to set the channel founder authentication data. A client can
2529 claim the founder rights later by providing the authentication
2530 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2531 This way the channel founder can regain the channel founder
2532 privileges even it is left the channel. This works only on
2533 local server and the client must be connected to the same
2534 server to be able to regain the founder rights. Updated the
2535 protocol specs accordingly.
2537 Added support to the CMODE command in the client to set the
2538 founder auth data. Read the README to see how to set it.
2540 Added support to the CUMODE command to claim the founder
2541 rights. Read the README to see how to do it.
2543 Added support for the founder authentication to the Channel
2544 Entry in the server. Affected file silcd/idlist.h.
2546 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2547 server's CMODE command. Affected file silcd/command.c.
2549 * Added the following new functions into lib/silccore/silcauth.[ch]:
2550 silc_auth_get_method and silc_auth_get_data.
2552 * The server now saves the remote hosts public key to the
2553 SilcIDListData pointer. Affected file silcd/protocol.c.
2555 * The normal server now does not remove the channel entry from
2556 the cache if the founder authentication data is set. It used
2557 to remove it if the founder was the last one on the channel on
2558 the server and left the channel. The auth data is saved and
2559 if the channel is re-joined later the old entry is used with
2560 the old auth data. Affected files silcd/command_reply.c and
2563 * Removed the `pkcs' field from the SilcIDListData structure
2564 in the server; it is not used. Affected file silcd/idlist.h.
2566 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Fixed packet processing on slow links. Partial packets were
2569 never re-processed because the incoming data buffer was cleared
2570 by the application. Application must not directly clear the
2571 sock->inbuf, the packet processing routines handle it. Fixed
2572 this in client library and in server.
2574 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Fixed the WHOIS and IDENTIFY send reply function to really
2577 check whether to send list or just one entry. Affected file
2580 * Cleaned up the LEAVE command's channel key distribution. The
2581 affected file silcd/command.c.
2583 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2584 can enforce the channel mode as well. In that case the ID
2585 includes the ID of the server. The code now enforces the
2586 mode change if the router have different mode than the server.
2588 * The notify client operation with CMODE_CHANGE notify can now
2589 return NULL client_entry pointer if the CMODE was not changed
2590 by client. Application must check for this.
2592 * Added <Server ID> argument to INFO command to support server
2593 info fetching by Server ID.
2595 * Added silc_server_announce_get_channel_users to get assembled
2596 packets of channel users of the specified channel. Affected
2597 file silcd/server.[ch].
2599 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2600 was freed underneath the ID Cache.
2602 * Re-announce clients when the server received CHANNEL_CHANGE
2603 notify from the router. Affected file silcd/packet_send.c.
2605 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2608 crashed since it did not handle the fact that there is no cipher
2609 called "3" and didn't check the error condition. Now fixed.
2611 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2612 flag. It can be used to send message requests.
2614 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Implemented the RESTART command in the client.
2618 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2619 notice type messages. Added notice printing to the user
2622 * The channel keys are not re-generated if the channel's mode
2623 is PRIVKEY, ie private key on the channel exists. Affected
2624 files silcd/server.c and silcd/command.c.
2626 * Fixed a little bug in channel message delivery when channel
2627 private keys are set in the server. Affected file is
2628 silcd/packet_send.c.
2630 * Changed the setting on channel->on_channel = TRUE from the
2631 silc_client_save_channel_key to the JOIN command reply. The
2632 key payload is not received if the private channel key is set.
2633 Affected file lib/silcclient/command_reply.c and the
2634 lib/silcclient/client_channel.c.
2636 * When the CMODE_CHANGE notify is sent and the channel private
2637 key mode is removed the channel key must be re-generated in
2638 other cells as well. Added this support for the router in the
2639 silcd/packet_receive.c.
2641 * Added new local command NOTICE to send notice message on
2642 channel. Affected file silc/local_command.[ch].
2644 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Added new local command ME to the client. It is used to send
2647 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2648 some action. Affected file silc/local_command.[ch].
2650 * Changed channel_message and private_message client operations
2651 to deliver the message flags to the application. Added also
2652 the `flags' arguments to the silc_client_send_channel_message
2653 and silc_client_send_private_message functions. Affected file
2656 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Redefined the Private Message Payload to support private message
2659 keys and to support the new private message flags. Updated
2660 the protocol specs. Flags makes it possible to have for example
2661 CTCP style messages.
2663 * Added new type SilcPrivateMessagePayload and defined an API
2664 for it in the lib/silcclient/silcprivate.[ch].
2666 * Tested private message private keys successfully. Tested the
2667 private message key set, unset and list commands with the new
2670 * Redefined the Channel Message Payload to include the channel
2671 message flags (equal with private message flags) to support
2672 for example CTCP style messages.
2674 * Defined some of the message (for channel and private message)
2675 flags. Updated the protocol specs and added the flags to the
2676 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2678 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Added SilcKeyAgreementStatus type to the key agreement routines
2681 to indicate the current status and error if one occured.
2682 The status types are defined in the lib/silcclient/silcapi.h.
2684 * Added new local command KEY that is used to set and unset private
2685 keys for channels, set and unset private keys for private messages
2686 with remote clients and to send key agreement requests and
2687 negotiate the key agreement protocol with remote client. The
2688 key agreement is supported only to negotiate private message keys,
2689 it currently cannot be used to negotiate private keys for channels,
2690 as it is not convenient for that purpose.
2692 * Fixed a minor pending callback setting bug in the function
2693 silc_client_get_client_by_id_resolve, now the function works.
2694 Affected file lib/silcclient/idlist.c.
2696 * Added function silc_net_get_local_port to get local bound
2697 port by socket. Added to lib/silcutil/silcnet.[ch].
2699 * Added `sockets' and `sockets_count' fields to the SilcClient
2700 object. They hold the sockets of the listenning sockets in
2701 the client. Listenning sockets may be for example the key
2702 agreement server. Affected file lib/silcclient/client.[ch].
2703 Added functions the silc_client_add_socket and the
2704 silc_client_del_socket. They are exported to the application
2707 * Added ~./silc/clientkeys to support other client's public keys.
2709 * Renamed verify_server_key client operation to verify_public_key
2710 and added one argument to indicate the type of the connection
2711 (server, client etc.).
2713 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Added silc_server_connection_auth_request to handle the
2716 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2717 silcd/packet_receive.[ch].
2719 * Added silc_server_send_connection_auth_request into the
2720 silcd/packet_send.c to send the connection auth request packet.
2722 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2725 * Fixed the public key authentication in responder side in the
2726 server. The `auth_data' pointer includes the SilcPublicKey
2727 not the path to the public key. Affected file silcd/protocol.c.
2729 * Implemented the public key authentication in the initiator side
2730 in the server. Affected file silcd/protocol.c.
2732 * Removed the [RedirectClient] config section from the server
2733 configuration. Is not needed and I don't want to implement it.
2735 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Cleaned up the CMODE command in the server. It now works
2738 correctly and supports all the modes defined in the protocol.
2739 Affected file is silcd/command.c.
2741 * Added `hmac_name' field to the SilcChannelEntry in the server
2742 to hold the default HMAC of the channel. It can be set when
2743 creating the channel (with JOIN command). Affected files
2746 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2747 type to indicate the change of the current cipher and hmac
2748 on the channel. Client can safely ignore the <cipher> argument
2749 (if it chooses to do so) since the CHANNEL_KEY packet will
2750 force the channel key change anyway. The <hmac> argument is
2751 important since the client is responsible of setting the new
2752 HMAC and the hmac key into use.
2754 * Fixed the CMODE command in the client library as well.
2756 * Tested CMODE command in router environment successfully.
2758 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Show the version of the remote client (or server) when connecting
2761 to the server. It is logged to the log file. Affected file
2762 is silcd/protocol.c.
2764 * Fixed the KILLED notify handling in the client library. The
2765 client must be removed from all channels when receiving the
2768 Also, do not remove the client entry when giving the KILL
2769 command but when the KILLED notify is received.
2771 * Removed silc_idlist_find_client_by_nickname from the server.
2772 Not needed anymore. Affected files silcd/idlist.[ch].
2774 * Implemented the CHANNEL_CHANGE notify type handling to the
2775 server. Affected file silcd/server.c.
2779 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Added silc_server_send_notify_invite to send the INVITE
2782 notify between routers.
2784 * Implemented the INVITE command correctly to the server.
2786 * Implemented the INVITE notify type handling in the server.
2788 * Implemented the INVITE command to the client library and on the
2791 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Added function silc_server_get_client_resolve to find the
2794 client entry by ID from all ID lists and then resolve it
2795 (using WHOIS) if it cannot be found. Affected file is
2798 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Implemented the BAN command to the client library.
2802 * The JOIN command in the server now checks the invite list
2805 * Changed the silc_command_reply_payload_encode_va and the
2806 silc_command_payload_encode_va to support that if argument is
2807 NULL it ignores and checks the next argument. Affected file
2808 lib/silccore/silccommand.c.
2810 * Added silc_server_send_notify_ban to send the BAN notify
2811 type between routers.
2813 * Chaned the silc_notify_payload_encode to support that if
2814 argument is NULL it ignores and checks the next argument.
2815 Affected file lib/silccore/silcnotify.c.
2817 * Tested ban lists in router environment successfully.
2819 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2821 * Implemented BAN command to the server, in silcd/command.[ch].
2823 * Removed the BAN and INVITE_LIST modes from the CMODE command
2826 * Added function silc_string_match to regex match two strings.
2827 Affected files lib/silcutil/silcutil.[ch].
2829 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Redefined parts of the SilcChannelEntry in the server to support
2832 the new ban and invite lists.
2834 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Redefined the INVITE command. The same command can be used to
2837 invite individuals to the channel but also to manage the invite
2838 list of the channel (to add to and remove from the invite list).
2839 Updated the protocol specs.
2841 * Added new command SILC_COMMAND_BAN that can be used to manage
2842 the ban list of the channel. Updated the protocol specs.
2844 * Removed the channel modes: the SILC_CMODE_BAN and the
2845 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2846 in the CMODE command. The equivalent features are now available
2847 using INVITE and BAN commands. Updated the protocol specs.
2849 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2850 in the network about change in the current ban list. The notify
2851 type is not used by the client.
2853 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2854 support the invite lists.
2856 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Added new function silc_string_regexify that converts string
2859 including wildcard characters into regex string that can
2860 be used by the GNU regex library. Added into the file
2861 lib/silcutil/silcutil.[ch].
2863 Added silc_string_regex_combine to combine to regex strings
2864 into one so that they can be used as one regex string by
2865 the GNU regex library. Added into the file
2866 lib/silcutil/silcutil.[ch].
2868 Added silc_string_regex_match to match two strings. It returns
2869 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2871 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Imported GNU regex to the soruce tree into lib/contrib.
2874 Fixed some compiler warning from the regex.c.
2876 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Fixed MOTD command in the server to work in router environment.
2880 * Fixed the MOTD command in the client library to support
2881 the server argument in the command.
2883 * Added `nickname_len' argument to the silc_idlist_add_client
2884 in the server, as the `nickname' argument may be binary data
2887 * Added silc_idlist_get_channels to return all channels from
2890 * Implemented LIST command to the server. Affected file is
2893 * Implemented the LIST command to the client library and on the
2896 * Added [<user count>] argument to the LIST command reply.
2897 With private channels the user count is not shown.
2899 * Updated TODO and README.
2901 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * The client entry's data.registered must be TRUE even with
2904 global client entry on global client list. The data.registered
2905 is used to check whether the client is anymore in the network,
2906 for example with WHOWAS command so it must be valid.
2908 * Fixed the WHOWAS command in the server. It now actually works
2909 in router environment. Added function into silcd/command_reply.c
2910 silc_server_command_reply_whowas_save.
2912 * Added silc_idlist_purge function to the silcd/idlist.c
2913 to periodically purge the ID Cache.
2915 * Fixed INFO command in the server. It works now in router
2916 environment. Added <server name> argument to the INFO command
2917 reply. Updated the protocol specs.
2919 * Fixed minor bug in silc_idcache_purge to not purge if the
2920 expire value is zero.
2922 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2923 they were buggy because of the WHOWAS information.
2925 * Fixed local command MSG to handle the async resolving of
2926 the remote client properly. It used to fail the first MSG.
2927 Affected file silc/local_command.c.
2929 * Added `data_len' field to SilcIDCache context.
2931 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Update TODO. Todo in commands in the server.
2935 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2938 used by routers as broadcast packet to inform other routers
2939 about the changed user mode.
2941 Implemented the notify handling in the server. Affected file is
2942 silcd/packet_receive.c. Added the function
2943 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2945 * Added new generic Channel Payload and deprecated the New Channel
2946 Payload. The New Channel Payload is now the generic Channel
2949 * Added new argument `mode' to the silc_server_send_new_channel
2950 as it is required in the Channel Payload now.
2952 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2953 and created a new and real SilChannelPayload to represent the
2954 new generic Channel Payload. Implemented the encode/decode
2955 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2957 * Added silc_server_get_client_channel_list to return the list
2958 of channels the client has joined for WHOIS command reply.
2959 Affected file silcd/server.[ch].
2961 * Implemented the channel list sending in the WHOIS command reply
2962 in server and in the client.
2964 Implemented the channel list displaying on the user interface
2965 as well. Affected file silc/client_ops.c.
2967 * Added silc_channel_payload_parse_list to parse list of Channel
2968 Payloads. It returns SilcDList list of SilcChannelPayloads.
2969 Client for example can use this function to parse the list of
2970 channels it receives in the WHOIS command reply. The caller
2971 must free the list by calling silc_channel_payload_list_free.
2972 Affected files lib/silccore/silcchannel.[ch].
2974 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Added one new argument <user mode> to the WHOIS command reply
2977 to return the mode of the user in SILC. Updated the protocol
2980 Implemented it to the server and client.
2982 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Fixed the mode printing on the user interface on joining.
2985 Affected file silc/client_ops.c.
2987 * Implemented the UMODE command and user modes in general to the
2988 client library and to the user interface.
2990 * Implemented the UMODE command to the server.
2992 * The server now sends UNKNOWN_COMMAND error status if client sends
2993 unknown command. Affected file silcd/command.c.
2995 * All server commands now handle the command identifier the right
2996 way when sending the command reply to the client. The client can
2997 use to identify the command replies with the identifier.
2999 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Added silc_server_get_client_route to resolve the route to
3002 the client indicated by the client ID. Affected file is
3005 * Added silc_server_relay_packet as general function to relay
3006 packet to arbitrary destination. This deprecates functions
3007 like _send_private_message_key, _relay_notify etc. Affected
3008 file is silcd/packet_send.[ch].
3010 Removed silc_server_send_key_agreement,
3011 silc_server_send_private_message_key and
3012 silc_server_packet_relay_notify functions from the file
3013 silcd/packet_send.[ch].
3017 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3018 server. Affected file silcd/packet_receive.[ch].
3020 * Implemented the KILL command to the client. Implemented the
3021 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3022 Affected files lib/silcclient/command[_reply].c and
3023 lib/silcclient/client_notify.c. Implemented the KILL notify
3024 printing in the user inteface.
3026 * Fixed a lot silc_parse_nick memory leaks from the client
3027 library in the file lib/silcclient/command.c.
3029 * Changed the silc_server_send_notify_on_channels's `sender'
3030 argument from SilcSocketConnection to SilcClientEntry to
3031 check the sender as entry and not as connection object and not
3032 to send to the client provided as argument. The affected file
3033 is silcd/packet_send.[ch].
3035 * The notify packets that are destined directly to the client used
3036 to not to be processed by the server. Now changed that and the
3037 server processes all notify packets. After relaying the packet
3038 to the client the notify packet is processed in the server.
3040 * The silc_server_free_client_data now checks whether there is
3041 pending outgoing traffic for the client and purges the data to
3042 the network before removing the client entry.
3044 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3047 an client is killed from the SILC Network. Updated the protocol
3050 Added new function silc_server_send_notify_killed to the
3051 silcd/packet_send.[ch].
3053 * Added function silc_server_packet_relay_notify to relay notify
3054 packets that are destined directly to a client. In this case
3055 the server does not process the notify packets but merely relays
3056 it to the client. Affected file silcd/packet_send.[ch].
3058 Added also silc_server_packet_process_relay_notify to check
3059 whereto relay the notify. Affected file is
3060 silcd/packet_receive.[ch].
3062 * Implemented the KILL command to the server.
3066 * Added the backup schema desgined last fall to the protocol
3067 specs for everyone to see. The specification is in the
3068 *-spec-xx.txt draft and the packet type definitions for the
3069 backup routers is in *-pp-xx.txt draft. Thusly, added also
3070 new packet type SILC_PACKET_CELL_ROUTERS.
3072 * A big security problem in the implementation discovered. The
3073 signoff of an client did not cause new channel key generation
3074 which it of course should've done. The channel keys must be
3075 always re-generated when client leaves (or signoffs) the channel.
3076 The silc_server_remove_from_channels funtion now handles
3077 the channel key re-generation.
3079 * Added `sender' argument to the silc_server_send_notify_on_channels
3080 to not to send the client provided as argument. Affected file
3081 silcd/packet_send.[ch].
3083 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Implemented OPER and SILCOPER commands into the server and
3088 * Added silc_auth_verify and silc_auth_verify_data to verify
3089 the authentication directly from the authentication payload.
3090 It supports verifying both passphrase and public key based
3091 authentication. Affected file lib/silccore/silcauth.[ch].
3093 * Added `hash' field to the SilcIDListData structure. It is the
3094 hash negotiated in the SKE protocol. Affected file is
3097 * Slight redesigning of the SilcAuthPayload handling routines.
3098 Do not send SilcPKCS but SilcPublicKey as argument.
3100 * Implemented the public key authentication support to the
3101 serverconfig. The public key is loaded from the provided path
3102 and saved as authentication data to void * pointer. Thus,
3103 changed the unsigned char *auth_data to void *auth_data;
3105 * Fixed SHUTDOWN command to send the reply before the server
3106 is shutdown. :) Affected file silcd/command.c.
3108 * Fixed fatal bug in CONNECT command. The hostname was invalid
3109 memory and server crashed. Affected file silcd/command.c.
3111 * Fixed fatal bug in CLOSE command. The server_entry became
3112 invalid but was referenced later in the command. Affected file
3115 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Fixed fatal bug in failure packet handling. Server ignored
3118 the failure and thus crashed when it came.
3122 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3125 that the command may be executed only once in (about) 2 seconds.
3126 The old SILC_CF_LAG flag is same but allows command bursts up
3127 to five before limiting.
3129 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3130 server code. Various commands now includes the CF_LAG_STRICT
3131 flag to disallow any kind of miss-use of the command.
3133 * Fixed the silc_buffer_unformat to not to allocate any data
3134 if the length of the data is zero. It used to allocate the
3135 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3137 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Changed the format of AdminConnection configuration section
3140 in the server. Added username of the admin to the format.
3141 Affected files silcd/serverconfig.[ch].
3143 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3144 to return admin configuration data by host, username and/or
3147 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Implemented WHOWAS command to the server. Added the functions:
3151 silc_server_command_whowas_parse,
3152 silc_server_command_whowas_send_reply,
3153 silc_server_command_whowas_from_client and
3154 silc_server_command_whowas_from_server
3156 * Added <Client ID> argument to the WHOWAS command reply. Updated
3157 the protocol specs accordingly.
3159 * Implemented WHOWAS command and command_reply to the client
3162 Implemented the WHOWAS printing on the user interface.
3164 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Added new argument to the WHOWAS command reply, the real name.
3167 It is an optional argument. Updated the protocol specs.
3169 * Added SilcIDCacheDestructor callback that is registered when
3170 the SilcIDCache is allocated. The callback is called when
3171 an cache entry in the ID Cache expires, or is purged from the
3172 cache. Added into lib/silccore/idcache.[ch].
3174 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3175 to destruct the client entries when the cache entry expires.
3176 Other ID Cache's in server and in the client library ignores
3179 * If the ID Cache entry's `expire' field is zero then the entry
3180 never expires. Added boolean `expire' argument to the
3181 silc_idcache_add function in the lib/silccore/idcache.[ch].
3182 If it is TRUE the default expiry value is used.
3184 * Added silc_server_free_client_data_timeout that is registered
3185 when client disconnects. By default for 5 minutes we preserve
3186 the client entry for history - for WHOWAS command.
3188 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Added support to the server to enforce that commands are not
3191 executed more than once in 2 seconds. If server receives
3192 commands from client more frequently, timeout is registered
3193 to process the commands. Affected file silcd/command.c.
3194 Added new function silc_server_command_process_timeout.
3196 * Changed NICK_NOTIFY handling in client library to check that
3197 if the client's nickname was changed, so there is no need to
3198 resolve anything from the server.
3200 * Removed error printing from the WHOIS and IDENTIFY commands.
3201 If error occurs then it is ignored silently in the client library.
3202 The application, however, may map the received error to
3203 human readable error string. The application currently maps
3204 the NO_SUCH_NICKNAME error to string.
3206 * Made the command status message public to the application. Moved
3207 them from lib/silcclient/command_reply.c to
3208 lib/silcclient/command_reply.h. The application can map the
3209 received command status to the string with the
3210 silc_client_command_status_message function.
3212 * Added check to the server to check that client's ID is same
3213 as the Source ID in the packet the client sent. They must
3216 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Added dist-bzip hook to the Makefile.am to make bzip2
3219 compressed distributions.
3221 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Server now enforces the maximum length for the nickname and
3224 the channel as protocol specification dictates. 128 bytes for
3225 nickname and 256 bytes for channel name.
3227 * Moved the WHOIS printing to the application. The client libary
3228 does not print out the WHOIS information anymore, the application
3229 must do it. Renamed silc_client_command_reply_whois_print to
3230 the silc_client_command_reply_whois_save.
3232 The client's idle time is also sent to the application now, and
3233 the idle is shown on screen.
3235 * Added silc_client_command_reply_identify_save to save the
3236 received IDENTIFY entries.
3238 * Do not check for channel private keys in message sending and
3239 reception if the channel does not have the PRIVKEY mode set.
3240 Affected file lib/silclient/client_channel.c.
3242 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3245 just surfaced after chaning the JOIN procedure.
3247 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added silc_client_get_clients_by_list to get client entries
3250 from Client ID list, that is returned for example by JOIN
3251 and USERS command replies. The application should use this
3252 function for example when JOIN command reply is received to
3253 resolve the clients already on the channel (library does not
3254 do that anymore as USERS command reply is not used in the JOIN
3255 procedure anymore). Affected files lib/silcclient/silcapi.h and
3256 lib/silcclient/idlist.c.
3258 * JOIN command reply and USERS command reply returns now SilcBuffer
3259 pointers instead of unsigned char pointers when returning
3260 the client list and mode list.
3262 * Added <Client ID> argument to the JOIN command reply, mainly
3263 for the server to identify for which client the command was
3264 originally sent. Updated protocol specs accordingly.
3266 * Added SilcDlist private_key pointer to the SilcChannelEntry
3267 in the client to support the channel private keys. Affected
3268 file is lib/silcclient/idlist.h.
3270 * Added SilcChannelPrivateKey argument to the function
3271 silc_client_send_channel_message so that application can choose
3272 to use specific private ke if it wants to. If it is not provided,
3273 the normal channel key is used, unless private keys are set.
3274 In this case the first (key that was added first) is used
3275 as the encryption key.
3277 * Implemented the support for channel private key handling.
3278 Implemented the following functions:
3280 silc_client_add_channel_private_key,
3281 silc_client_del_channel_private_keys,
3282 silc_client_del_channel_private_key,
3283 silc_client_list_channel_private_keys and
3284 silc_client_free_channel_private_keys
3286 Affected file lib/silcclient/client_channel.c.
3288 * Added the support for the private keys in the channel message
3289 sending and encryption and in the message reception and
3290 decryption. Affected funtions are
3291 silc_client_send_channel_message and silc_client_channel_message.
3293 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Added SKE's key verify callback to the client library's
3296 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3298 * Removed the statement that server (or router) must send USERS
3299 command reply when joining to the channel so that the client
3300 knows who are on the channel. Instead, the client list and
3301 client's mode list is now sent in the JOIN command reply to the
3302 client who joined channel. This is better solution.
3304 * Added function silc_server_get_users_on_channel and function
3305 silc_server_save_users_on_channel to the silcd/server.[ch].
3307 * Removed function silc_server_command_send_users from the
3310 * Do not show topic on the client library anymore. The topic is
3311 sent in the command reply notify to the application and the
3312 application must show the topic now.
3314 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Added client searching by nickname hash into the IDENTIFY and
3317 WHOIS commands in the server as they were clearly missing from
3318 them. Affected file is silcd/command.c.
3320 * Fixed a bug in private message receiving in the client library.
3321 The remote ID was freed and it wasn't supposed, now it is
3324 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Minor fix to the channel payload; allocate the data area, as it
3327 needs to be of specific length.
3329 * If the key agreement port is zero then the operating
3330 system will define the bound port. Affected files are
3331 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3333 * Added new function silc_channel_payload_decrypt into the file
3334 lib/silccore/silcchannel.[ch].
3336 * Moved the channel message etc, check from silc_packet_decrypt
3337 to applications. The library calls now a generic
3338 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3339 when the packet is either normal or special. This was done to
3340 allow more wide range of checking that was not allowed when
3341 the code was in library. Now applications can do virtually any
3342 checks to the packet and return to the library the decision how
3343 the packet should be processed. Affected files are
3344 lib/silccore/silcpacket.[ch].
3346 Added silc_server_packet_decrypt_check to the server and
3347 silc_client_packet_decrypt_check to the client library.
3349 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3350 to send with specified source and destination information.
3352 * Channel message delivery between routers was broken after the
3353 channel key distribution was fixed earlier. The channel key
3354 was used be to distributed to other routers as well which is not
3355 allowed by the protocol. Now this is fixed and channel keys
3356 really are cell specific and the channel message delivery between
3357 routers comply with the protocol specification.
3359 * Fixed various commands in server to check also the global list
3360 for the channel entry and not just the local list. The affected
3361 file silcd/command.c.
3363 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Added assert()s to buffer formatting and unformatting routines
3366 to assert (if --enable-debug) when error occurs. Affected
3367 file: lib/silcutil/silcbuffmt.c.
3369 * Changed to auto-reconnect to check whether the remote host is
3370 router and register the re-connect timeout if it is. It used
3371 to check that whether we are normal server, but router must do
3372 auto-reconnect with another router as well. Affected file
3375 * Removed the [<key len>] option from CMODE command as the cipher
3376 name decides the key length, nowadays. See the defined ciphers
3377 from the protocol specification.
3379 * Added [<hmac>] option to the CMODE command to define the HMAC
3380 for the channel. Added SILC_CMODE_HMAC channel mode.
3382 * Added [<hmac>] option for the JOIN command so that user can
3383 select which HMAC is used to compute the MACs of the channel
3386 * Added Hmac field to the Channel Message Payload. The integrity
3387 of plaintext channel messages are now protected by computing
3388 MAC of the message and attaching the MAC to the payload. The
3389 MAC is encrypted. Now, it is clear that this causes some
3390 overhead to the size of the packet but rationale for this is that
3391 now the receiver can verify whether the channel message decrypted
3392 correctly and also when private keys are set for the channel the
3393 receiver can decrypt the packet with several keys and check from
3394 the MAC which key decrypted the message correctly.
3396 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3397 lib/silccrypt/silccipher.[ch].
3399 * Added silc_hash_len to return the digest length into the
3400 lib/silcrypt/silchash.[ch].
3402 * Rewrote parts of Silc Channel Payload interface in the
3403 lib/silccore/silcchannel.[ch]. The encode function now also
3404 encrypts the packet and parse function decrypts it.
3406 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Fixed a minor formatting bug in the SKE's key material processing.
3409 It actually might have processed the keys wrong way resulting
3412 * Redefined the mandatory HMAC algorithms and added new algorithms.
3413 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3414 and hmac-md5 truncated to 96 bits. The mandatory is now
3415 hmac-sha1-96. Rest are optional (including the one that used
3416 to be mandatory). Rationale for this is that the truncated HMAC
3417 length is sufficient from security point of view and can actually
3418 make the attack against the HMAC harder. Also, the truncated
3419 HMAC causes less overhead to the packets. See the RFC2104 for
3422 * Added new [hmac] configuration section. The SKE used to use
3423 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3424 is of course wrong. The official names that must be proposed in
3425 the SKE are the ones defined in the protocol specification
3426 (hmac-sha1-96 for example). The user can configure any hmac
3427 using any hash function configured in the [hash] section. At
3428 least, the mandatory must be configured.
3430 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3432 * Added HMAC list to the SKE proposal list. It has now both
3433 hash algorithm list and HMAC list. This makes the protocol
3434 incompatible with previous versions. The SKE now seems to work
3435 the way it is supposed to work, for the first time actually.
3437 * Defined plain Hash algorithms to the protocol specification.
3440 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Implemented support for key agreement packets into the server.
3443 Added functions silc_server_key_agreement and
3444 silc_server_send_key_agreement. Other than these functions,
3445 server has nothing to do with this packet.
3447 * Added support for private message key packets into the server.
3448 Added functions silc_server_private_message_key and
3449 silc_server_send_private_message_key.
3453 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3454 called in the protocol's final callback instead in the END
3455 protocol state. This makes a little more sense and in the same
3456 time in client we can use the same protocol routines for normal
3457 key exchange and to key agreement packet handling as well.
3459 * Added to both client's and server's KE protocol context the
3460 SilcSKEKeyMaterial pointer to save the key material. We will
3461 bring the key material to the protocol's final callback by doing
3462 this. The final callback must free the key material.
3464 * Added SKE's packet_send callback into client's KE protocol
3465 context so that the caller can choose what packet sending function
3466 is used. This way we can use different packet sending when
3467 doing normal SKE when doing key agreement packet handling (in
3468 the key agreement packet handling we do not want to encrypt
3471 * Implemented the responder side of the key agreement routines
3472 in the client. The client can now bind to specified port and
3473 accept incoming key negotiation. The key material is passed
3474 to the application after the protocol is over.
3476 * Implemented the processing of incoming Key Agreement packet
3477 in the client. Added function silc_client_key_agreement to
3480 * Implemented the intiator side of the key agreement routines
3481 in the client. The client can now initiate key agreement with
3482 another remote client. The key material is passed to the
3483 application after the protocol is over.
3485 * Created client_keyagr.c to include all the key agreement
3488 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3489 SILC_TASK_CALLBACK except that it is not static.
3491 * Created client_notify.c and moved the Notify packet handling
3492 from the client.[ch] into that file.
3494 * Created client_prvmsg.c and moved all private message and
3495 private message key routines from the client.[ch] into that file.
3497 * Create client_channel.c and moved all channel message and
3498 channel private key routines from the client.[ch] into that file.
3500 * Changed silc_client_get_client_by_id_resolve to resolve with
3501 WHOIS command instead of IDENTIFY command, in the file
3502 lib/silclient/idlist.c.
3504 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Implemented the SKE's responder side to the Client library.
3508 * When FAILURE is received to the protocol do not trust it
3509 blindly. Register a timeout to wait whether the remote closes
3510 the connection as it should do it, only after that process the
3511 actual failure. This was changed to both client and server.
3513 * Added client_internal.h to include some of the structures
3514 there instead of client.h in lib/silcclient/.
3516 * Added function silc_task_unregister_by_callback to unregister
3517 timeouts by the callback function.
3519 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Some "Incomplete WHOIS info" errors has been appearing on the
3522 log files. Took away the entry->userinfo check from WHOIS
3523 reply sending. The entry->userinfo is now " " if client did not
3524 provide one. I thought this was fixed earlier but something
3525 is wrong still. Let's see if the error still appears.
3527 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Fixed a minor bug in the login when the channel key is
3530 re-generated in the server. It used to generate the key in
3531 wrong order and thus caused problems in the channel traffic.
3533 * Fixed a minor bug in channel key distsribution after
3534 KICK command. The key was not sent to the router even though
3537 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Added silc_ske_process_key_material_data as generic routine
3540 to process any key material as the SILC protocol dictates. The
3541 function is used by the actual SKE library but can be used by
3542 applications as well. This relates to the private message keys
3543 and the channel private keys since they must be processed the
3544 same way the normal SILC session keys. The protocol dictates
3545 this. Affected files: lib/silcske/silcske.[ch].
3547 Added also silc_ske_free_key_material to free the
3548 SilcSKEKeyMaterial structure.
3550 * Defined silc_cipher_set_key function to set the key for
3551 cipher without using the object's method function. The affected
3552 files: lib/silccrypt/silccipher.[ch].
3554 * Implemented silc silc_client_add_private_message_key,
3555 silc_client_add_private_message_key_ske,
3556 silc_client_del_private_message_key,
3557 silc_client_list_private_message_keys and
3558 silc_client_free_private_message_keys functions in the
3561 Added functions silc_client_send_private_message_key to send
3562 the Private Message Key payload and silc_client_private_message_key
3563 to handle incoming Private Message Key payload.
3565 * Added Cipher field to the Private Message Key payload to set
3566 the cipher to be used. If ignored, the default cipher defined
3567 in the SILC protocol (aes-256-cbc) is used.
3569 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3571 * Removed lib/silcclient/ops.h file.
3573 Redefined parts of the SILC Client Library API. Created new
3574 file silcapi.h that deprecates the ops.h file and defines the
3575 published Client Library API. Defined also private message key
3576 API and channel private key API into the file.
3578 This is the file that the application must include from the
3579 SILC Client Library. Other files need not be included by
3580 the application anymore.
3582 * Added new key_agreement client operation callback and also
3583 defined the Key Agreement library API for the application.
3585 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3588 is used by clients to request key negotiation between another
3589 client in the SILC network. If the negotiation is started it
3590 is performed using the SKE protocol. The result of the
3591 negotiation, the secret key material, can be used for example
3592 as private message key.
3594 Implemented the Key Agreement payload into the files
3595 lib/silccore/silauth.[ch].
3597 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Redefined ciphers for the SILC protocol. Added some new ciphers
3600 and defined the key lengths for the algorithms. Changed the
3601 code accordingly. The default key length is now 256 bits.
3603 * Fixed SKE key distribution function silc_ske_process_key_material
3604 when the key length is more than 128 bits. The default key
3605 length in SILC is now 256 bits.
3607 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3608 to indicate unsupported algorithm.
3610 * Renamed rijndael.c to aes.c and all functions as well.
3612 * Fixed a long standing channel key setting bug in client library.
3613 Weird that it has never surfaced before.
3615 * Fixed bug in channel deletion. If the entire channel is removed
3616 then it must also delete the references of the channel entry
3617 from the client's channel list as the client's channel entry and
3618 the channel's client entry share same memory.
3620 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Implemented CONNECT and SHUTDOWN commands in the client.
3624 * Implemented CLOSE command to the client.
3626 * Added the function silc_idlist_find_server_by_name into the
3627 files silcd/idlist.[ch].
3629 Added the function silc_idlist_find_server_by_conn into the
3630 files silcd/idlist.[ch].
3632 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * DIE command was renamed to SHUTDOWN. Updated the both code
3637 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3638 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3640 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3643 * Added function silc_server_create_connection function to create
3644 connection to remote router. My server implementation actually
3645 does not allow router to connect to normal server (it expects
3646 that normal server always initiates the connection to the router)
3647 so the CONNECT command is only good for connecting to another
3650 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3653 or some other client was kicked from the channel.
3655 Implemented the handling of the notify type to both client
3658 Implemented silc_server_send_notify_kicked to send the KICKED
3659 notify. It is used to send it to the server's primary router.
3661 * Implemented the KICK command into server and client.
3663 * Added `query' argument to the silc_idlist_get_client function
3664 to indicate whether to query the client from server or not if
3667 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3668 to indicate that the client is not channel founder.
3672 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Removed the rng context from SilcPacketContext structure and
3675 changed that the packet routine uses the Global RNG API.
3677 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Added support for quit message that client can "leave" on the
3680 channel when it quits the SILC. It is ditributed inside the
3681 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3683 Added silc_server_free_client_data that will take the
3684 signoff message as argument.
3686 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3688 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Updated parts of the protocol specification to keep it up
3693 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3696 payloads in one packet.
3698 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3699 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3700 use now the new List flag.
3702 * Also deprecated the following packet types: REPLACE_ID,
3703 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3705 * Added list support for Notify packet in server.
3707 * Added silc_server_send_notify_channel_change to send the
3708 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3709 the silc_server_send_replace_id.
3711 * Added silc_server_send_notify_nick_change to send the
3712 NICK_CHANGE notify type. Deprecates the function
3713 silc_server_send_replace_id.
3715 * Added silc_server_send_notify_join to send the JOIN notify type.
3716 Deprecates the function silc_server_send_new_channel_user.
3718 * Added silc_server_send_notify_leave to send LEAVE notify type.
3719 Deprecates the function silc_server_send_remove_channel_user.
3721 * Added silc_server_send_notify_cmode and
3722 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3723 types. Deprecates the silc_server_send_set_mode function.
3725 * Added SERVER_SIGNOFF notify type to indicate that server has
3726 quit. This means that all clients on the channel from that
3727 server will drop. This can be also used when netsplit happens.
3729 Deprecated REMOVE_ID packet type since it is not needed anymore
3732 Added silc_server_send_notify_server_signoff to send the
3733 SERVER_SIGNOFF notify type. Deprecates the function
3734 silc_server_send_remove_id.
3736 Added also silc_server_send_notify_signoff to send the
3737 SIGNOFF notify type.
3739 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3740 SILC protocol from this day on. Changed the protocol
3741 specification as well.
3743 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3744 notify type. It is used between routers to notify about
3745 topic changes on a channel.
3747 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3750 * Partly updated the protocol specification to comply with the
3751 changes now made. It is still though a bit outdated.
3753 * The JOIN notify type now takes one extra argument <Channel ID>.
3754 The packet used to be destined to the channel but now the
3755 JOIN type may be sent as list thus it is impossible to
3756 destine it to any specific channel. By adding this argument
3757 it is again possible.
3759 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Added CREDITS file. The CHANGES and CREDITS file will appear
3762 in the distribution as well.
3764 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3767 types in the server's silcd/packet_receive.c.
3769 * Implemented CMODE and CUMODE to work in router environment.
3771 * Fixed minor encoding and decoding buglet from the
3772 lib/silccore/silcmode.c.
3774 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3777 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3779 * Changed all SilcConfigServer* and silc_config_server* to
3780 SilcServerConfig* and silc_server_config*, respectively.
3783 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Associated the ID (client or server ID) to the Authentication
3786 Payload to avoid any possibility of forging. Updated the
3787 protocol specification and the code accordingly.
3789 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * The RSA key length is now save to the RsaKey context in the
3792 key generation process in lib/silccrypt/rsa.c. The key length
3793 is now used to figure out the maximum size of the block allowed
3794 to be encrypted/signed.
3796 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3797 is equivalent to the silc_mp_mp2bin but does not allocate any
3800 * Changed silc_mp_mp2bin API to take length argument. If it is
3801 non-zero then the buffer is allocated that large. If zero, then
3802 the size is approximated using silc_mp_sizeinbase, which however
3805 * Created Global RNG API which is global RNG that application can
3806 initialize. After initializing, any routine anywhere in the
3807 code (including library) can use RNG without allocating a new
3808 RNG object. This was done to allow this sort of use of the
3809 RNG in code that has no chance to allocate RNG object. All
3810 applications currently allocate this and many routines in the
3811 library use this. Affected file lib/silccrypt/silcrng.[ch].
3813 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3814 it to use the Global RNG API.
3816 * Defined Authentication Payload into protocol specification that
3817 is used during SILC session to authenticate entities. It is
3818 used for example by client to authenticate itself to the server
3819 to obtain server operator privileges.
3821 Implemented this payload into the lib/silccore/silcauth.[ch].
3822 Implemented also routines for public key based authentication
3823 as the new protocol specification dictates.
3825 Moved definitions of different authentication methods from
3826 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3828 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3829 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3830 silc_pkcs_verify_with_hash functions into the file
3831 lib/silccrypt/silcpkcs.[ch].
3833 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * The client entry's userinfo pointer must be always valid.
3836 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3837 will fail since it requires the userinfo. Now, the userinfo
3838 is allocated as "" if actual userinfo does not exist. Actually,
3839 it must exist and it is totally Ok to drop client connections
3840 that does not announce the userinfo. However, we will make
3841 this workaround for now.
3843 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3844 to return the remote port by socket.
3846 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3849 SILC_SERVER_PENDING_EXEC and added an new macro
3850 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3851 data or when error occurs while processing the pending command.
3853 Added new argument `destructor' into silc_server_command_pending
3854 and to the SilcServerCommandPending object. This destructor is
3855 now called after calling the pending callback or if error occurs
3856 immediately. If error occurs the actual pending callback won't
3857 be called at all - only the destructor. The destructor may be
3858 NULL if destructor is not needed.
3860 All this applies for client library code as well. Similar
3861 changes were made there as well for the pending commands.
3863 In the client, the application must now allocate the
3864 SilcClientCommandContext with the silc_client_command_alloc
3867 * Added reference counter to the SilcServerCommandContext. Added
3868 function silc_server_command_alloc and silc_server_command_dup
3871 Same type of functions added to the client library for the same
3874 * Removed the cmd_ident from IDListData away since it is now
3875 global for all connections. It is the command identifier used
3876 in command sending and with pending commands. The affected file
3879 * Added reference counter to the SilcSocketConnection objecet to
3880 indicate the usage count of the object. The object won't be
3881 freed untill the reference counter hits zero. Currently only
3882 server uses this, and client ignores it. The client must be
3883 set to use this too later. The affected files are
3884 lib/silccore/silcsockconn.[ch]. Added also the function
3885 silc_socket_dup to increase the reference counter.
3887 This was mainly added because it is possible that the socket
3888 is removed underneath of pending command or other async
3889 operation. Now it won't be free'd and proper DISCONNECTING
3890 flags, etc. can be set to avoid sending data to connection that
3891 is not valid anymore.
3893 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3894 the connection. After that it sets SILC_SET_DISCONNECTED.
3895 It is, however, possible that the socket data is not still freed.
3896 The silc_server_packet_process now checks that data is not
3897 read or written to connection that is DISCONNECTED. The socket
3898 get's freed when the reference counter hits zero.
3900 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Changed the client operation API: channel_message operation's
3903 `sender' is now the client entry of the sender, not the nickname
3904 and the `channel' is the channel entry, not the channel name.
3906 In the private_message operation the `sender' is now also the
3907 client entry of the sender not the nickname.
3909 Affected file is lib/silcclient/ops.h and all applications
3910 using the client operations.
3912 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Moved the calling of ops->connect() from connect_to_server_final
3915 into receive_new_id functin since that is the point when the
3916 client is actually allowed to send traffic to network. The
3917 affected file is lib/silcclient/client.c.
3919 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3922 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3923 (if needs broadcasting) instead of broadcasting the packets one
3924 by one which would make a burst in the network traffic.
3926 * Added `broadcast' argument to the functions in silcd/server.[ch]
3927 silc_server_create_new_channel[_with_id] to indicate whether
3928 to send New Channel packet to primary router.
3930 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Added new function into the silcd/server.[ch] files:
3933 silc_server_create_new_channel_with_id to create new channel with
3934 already existing Channel ID.
3936 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3937 lib/silccore/silcpacket.h. This packet is used t send list of
3938 Set Mode payloads inside one packet. Server uses this to set
3939 the modes for the channels and clients on those channels, that it
3940 announced to the router when it connected to it. The protocol
3941 specification has been updated accordingly.
3943 * The silc_server_new_channel did not handle the packet coming
3944 from normal server as it normally does not send that. However,
3945 when it announces its channels it does send it. Implemented
3946 the support for that.
3948 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3949 into the file lib/silccore/id.h.
3951 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Fixed memory leaks in the functions silc_idlist_del_client,
3954 silc_idlist_del_channel and silc_idlist_del_server in the file
3955 silcd/idlist.c. All of those leaked like a sieve.
3957 * Fixed some small memory leaks in the client's function
3958 silc_client_notify_by_server.
3960 * Added functions into silcd/server.c: silc_server_announce_clients,
3961 silc_server_announce_channels and silc_server_announce_server.
3962 These functions are used by normal and router server to announce
3963 to its primary router about clients, channels and servers (when
3964 router) that we own. This is done after we've connected to the
3967 These functions effectively implements the following packet types:
3968 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3969 and SILC_PACKET_NEW_ID_LIST.
3971 * Added new functions into the silcd/packet_receive.[ch]:
3972 silc_server_new_id_list, silc_server_new_channel_list and
3973 silc_server_new_channel_user_list to handle the incoming
3974 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3976 * Added support of changing Channel ID in the function
3977 silc_server_replace_id. If the server that announces a channel
3978 to the router already exists in the router (with same name but
3979 with different Channel ID), router is responsible to send
3980 Replace ID packet to the server and force the server to change
3981 the Channel ID to the one router has.
3983 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3984 client that the Channel ID has been changed by the router. The
3985 normal server sends this to the client. Client must start using
3986 the new Channel ID as the channel's ID.
3988 Implemented handling of this new type into lib/silcclient/client.c
3989 into the function silc_client_notify_by_server.
3991 * Added new function silc_idlist_replace_channel_id into the files
3992 silcd/idlist.[ch] to replace the Channel ID.
3994 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Call silc_server_command_identify_check always when processing
3997 the IDENTIFY command in silcd/command.c
3999 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4002 send keepalive packets. The packet can be sent by clients,
4003 servers and routers.
4005 Added function silc_socket_set_heartbeat into the file
4006 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4007 If not set, the heartbeat is not performed. The actual
4008 heartbeat is implemented in the low level socket connection
4009 library. However, application is responsible of actually
4012 Added silc_server_send_heartbeat to send the actual heartbeat
4013 packet into silcd/packet_send.[ch]. Server now performs
4014 keepalive with all connections.
4016 * Added silc_task_get_first function into lib/silcutil/silctask.c
4017 to return the timeout task with shortest timeout. There was a bug
4018 in task unregistration that caused problems. TODO has been
4019 updated to include that task system must be rewritten.
4021 * The client library will now resolve the client information when
4022 receiving JOIN notify from server for client that we know but
4023 have incomplete information.
4025 * Rewrote parts of silc_server_remove_from_channels and
4026 silc_server_remove_from_one_channel as they did not remove the
4027 channel in some circumstances even though they should've.
4029 * Encryption problem encountered in server:
4031 The LEAVE command used to send the Channel Key packet to the
4032 router immediately after generating it. However, the code
4033 had earlier sent Remove Channel user packet but not immediately,
4034 ie. it was put to queue. The order of packets in the router
4035 was that Channel Key packet was first and Remove Channel User
4036 packet was second, even though they were encrypted in the
4037 reverse order. For this reason, MAC check failed. Now, this
4038 is fixed by not sending the Channel Key packet immediately but
4039 putting it to queue. However, this is more fundamental problem:
4040 packets that are in queue should actually not be encrypted
4041 because packets that are sent immediately gets encrypted
4042 actually with wrong IV (and thus MAC check fails). So, packets
4043 that are in queue should be encrypted when they are sent to
4044 the wire and not when they put to the queue.
4046 However, the problem is that the current system has not been
4047 designed to work that way. Instead, the packet is encrypted
4048 as soon as possible and left to the queue. The queue is then
4049 just purged into wire. There won't be any fixes for this
4050 any time soon. So, the current semantic for packet sending
4053 o If you send packet to remote host and do not force the send
4054 (the packet will be in queue) then all subsequent packets to the
4055 same remote host must also be put to the queue. Only after the
4056 queue has been purged is it safe again to force the packet
4059 o If you send all packets immediately then it safe to send
4060 any of subsequent packets through the queue, however, after
4061 the first packet is put to queue then any subsequent packets
4062 must also be put to the queue.
4064 Follow these rules and everything works fine.
4066 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added new function silc_server_remove_clients_by_server to
4069 remove all client entries from ID list when the server connection
4070 is lost. In this case it is also important to invalidate all
4071 client entires as they hold the invalid server entry. This
4072 fixes fatal bug when server has lost connection and will reconnect
4075 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Made some sanity checks to silc_server_daemonise like to check
4078 whether the requested user and group actually exists.
4080 * Added sanity check to SKE's silc_ske_responder_finish to check
4081 that the public and private key actually is valid.
4083 * Invalidate the client's nickname when receiving Replace ID
4084 packet and the Client ID is being replaced. This means that the
4085 server will query the nickname if someone needs it (client)
4088 * Sort the ID Cache in client library when the ID Cache data
4089 has changed (needs sorting).
4091 * Do not allow for SILC client to create several connections to
4092 several servers. The client does not support windows right now
4093 and generating multiple connections causes weird behaviour.
4095 Irssi-silc client does support windows and can handle several
4096 connections without problems, see: www.irssi.org and SILC plugin.
4098 * Fixed some places where client was added to the IDList. The
4099 rule of thumb is following (in order to get everything right):
4100 If the client is directly connected local client then the
4101 `connection' argument must be set and `router' argument must be
4102 NULL to silc_idlist_add_client function. If the client is not
4103 directly connected client then the `router' argument must
4104 bet set and the `connection' argument must be NULL to the
4105 silc_idlist_add_client function.
4107 * The funtion silc_server_packet_send_local_channel actually did
4108 not check whether the client was locally connected or not. It
4109 does that now. Fixed a bug related to LEAVE command.
4111 * Fixed Remove Channel User payload parsing bug in server's
4112 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4114 * The server's silc_server_save_channel_key now checks also the
4115 global ID list for the channel as it might not be in the local
4116 list. Fixed a bug related to LEAVE command.
4118 * Is this the end of the [<unknown>] buglet that has been lurking
4119 around for a long time? A little for loop fix in server's
4120 silc_server_command_whois_parse that is used by both IDENTIFY
4121 and WHOIS command. At least, this was a clear bug and a cause
4122 of one type of [<unknown>] buglet.
4124 * WHOIS and IDENTIFY commands call the function
4125 silc_server_command_[whois/identify]_check function even if
4126 we are not router server.
4128 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added --with-gmp configuration option. If set the GMP
4131 is always compiled in the SILC source tree. If not set then
4132 it is checked whether the system has the GMP3 installed. If
4133 it has then the GMP won't be compiled (the system's headers
4134 and library is used), if it doesn't have it then the GMP is
4135 compiled in the SILC source tree.
4137 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Changed RSA private exponent generation to what PKCS #1
4140 suggests. We try to find the smallest possible d by doing
4141 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4142 not security fix but optimization.
4144 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Added new config entry [Identity] to fork the server and run
4147 it as specific user and group. A patch from Bostik.
4149 * Imported Dotconf configuration library into lib/dotconf.
4150 This will be used to create the SILC configuration files later.
4151 It will appear in the distsribution after this commit.
4153 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * A big code auditing weekend happening. Auditing code for
4156 obvious mistakes, bugs and errors. Also, removing any code
4159 Removed files for being obsolete:
4161 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4162 inline in the file lib/silcutil/silcbuffer.h)
4164 o lib/silcutil/silcbufutil.c (the header has inline versions)
4166 Changed code to fix possible error conditions:
4168 o The buffer formatting routines now check that the destination
4169 buffer really has enough space to add the data. This applies for
4170 both buffer formatting and unformatting
4171 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4172 unformatting was changed to accomodate following rules:
4173 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4174 sent to the function while XXX_*STRING will not allocate or copy
4175 the data into the buffer. Instead it sets the pointer from the
4176 buffer into the pointer sent as argument (XXX_*STRING used to
4177 require that the pointer must be allocated already). This change
4178 makes this whole thing a bit more consistent and more optimized
4179 (note that the data returned in the unformatting with XXX_*STRING
4180 must not be freed now). The routines return now -1 on error.
4182 o Tried to find all code that use buffer_format and buffer_unformat
4183 and added return value checking to prevent formatting and
4184 especially unformatting errors and possible subsequent fatal
4187 o Changed ske->x and ske->KEY to mallocated pointers in
4188 lib/silcske/silcske.h. Fixed possible data and memory leak.
4190 o Added return value checking to all *_parse* functions. Fixed
4191 many memory leaks as well.
4193 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4194 so that buffer overflows would not happen. All code now also
4195 checks the return value as it can fail.
4197 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Added reconnection support to server if the normal server looses
4200 its connection to the router (for example if router is rebooted).
4201 The server performs normal reconnection strategy implemented
4202 to the server. Affected file silcd/server.c.
4204 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Added new packet type SILC_PACKET_SET_MODE that is used to
4207 distribute the information about changed modes (for clients,
4208 channels and clients channel modes) to all routers in the
4209 network. Updated the protocol specification accordingly.
4211 Added functions into silcd/packet_send.c and
4212 silcd/packet_receive.c: silc_server_send_set_mode,
4213 silc_server_set_mode.
4215 Added new files silcmode.[ch] into lib/silccore that implements
4216 the encoding and decoding of Set Mode Payload. Added new type
4217 SilcSetModePayload. Moved the definitions of different modes
4218 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4220 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Oops, a little mistake in server's connection authentication
4223 protocol. The protocol is not ended with FAILURE but with
4224 SUCCESS if the authentication is Ok. :) Affected file is
4227 * Implemented NICK_CHANGE notify handling in server in the file
4228 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4229 the local clients on the channel. After the changing nickname
4230 in router environment snhould work and the [<unknown>] nickname
4231 should appear no more.
4233 The silc_server_replace_id function that receives the Replace ID
4234 payload now sends the NICK_CHANGE notify type also in the file
4235 silcd/packet_receive.c
4237 * Changed WHOIS and IDENTIFY command to support the maximum amount
4238 of arguments defined in protocol specs (3328 arguments). This
4239 fixed a bug that caused problems when there were more than three
4242 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added extra parameter, command identifier, to the
4245 silc_client_send_command so that explicit command identifier
4248 Changed that ID list routines uses specific command identifier
4249 when sending WHOIS/IDENTIFY requests to the server so that they
4250 can be identified when the reply comes back.
4252 Affected files lib/silcclient/command.[ch],
4253 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4255 * Added `sender' argument to silc_server_packet_send_to_channel
4256 to indicaet the sender who originally sent the packet to us
4257 that we are now re-sending. Ignored if NULL. Affected file
4258 silcd/packet_send.[ch].
4260 * Added some server statistics support in silcd/server_internal.h
4261 SilcServerStatistics structure and around the server code. Also
4262 send some nice statistics information when client is connecting
4265 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Fixed channel ID decoding in server's JOIN command reply in
4268 silcd/command_reply.c
4270 * Fixed braodcasting of replace ID payload to not to send it if
4271 we are standalone server in silcd/packet_receive.c.
4273 * Fixed all channel message sending routines to not to send
4274 packets to clients that has router set, since they are routed
4275 separately in the same function earlier. Affects file
4276 silcd/packet_send.c and all channel packet sending functions.
4278 * In USERS reply, res_argv[i] are not allocated, the table
4279 is allocated. Thus changed that free the table, not its
4282 * In server's whois_check and identify_check if the client is
4283 locally connected do not send any WHOIS commands - they are not
4286 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Fixed some minor bugs in client when sending WHOIS command. The
4289 arguments was in wrong order.
4291 * Removed statis function add_to_channel from server in
4292 silcd/command.c that was previously used with the joining but
4295 * Tested USERS command in router environment successfully with two
4296 routers, two servers and two clients.
4298 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Reorganized the USERS command and command reply in client library
4301 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4302 When the command is given by user we register a pending command
4303 callback that will reprocess the command after the reply has been
4304 received from the server. When reprocessing the packet we then
4305 display the information. Thus, the USERS information is displayed
4306 now in the command callback instead of in the command reply
4307 callback. The processing of the command is same as previously
4308 when server has sent the command reply in the JOINing process.
4310 * Added to USERS command in silcd/command_reply.c to join the client,
4311 we didn't use to know about, to the channel after we've created
4312 a client entry for it. Also, for clienet we did know already still
4313 check whether it is on the channel or not and add it if not.
4315 * Removed silc_server_command_join_notify as the function and its
4318 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Changed the client's pending command handling to the same as the
4321 server's pending command handling. It is also now possible to
4322 execute command reply functions from other command reply
4323 function as the function callbacks for commands and command
4324 replies are one and same. The pending commands are not static
4325 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4326 in client connection context. Thus, pending commands are server
4327 connection specific as it is convenient.
4329 Changed the function silc_client_command_pending and
4330 silc_client_command_pending_del and added new function
4331 silc_client_command_pending_check. Removed the
4332 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4335 * Added cmd_ident, current command identifier, to the client
4336 connection context in lib/silcclient/client.h to keep track on
4337 command identifiers used in command sending. Client's command reply
4338 function handling now supports the mandatory command identifiers.
4340 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4341 funtions in client to fully support pending command callbacks.
4343 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4344 as one of the arguments to the application in the command reply
4347 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4348 before first releasing SILC but came back. Now it is removed again
4349 and should come back nomore. The FORWARDED flag was used only
4350 by the JOINing procedure by forwarding the command packet to router.
4351 Now, the JOINing procedure has been changed to more generic (due
4352 to various router environment issues) and FORWARDED is not needed
4353 anymore for anything. The protocol specification is yet to be
4356 Now, removed silc_server_packet_forward from server and the flag
4357 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4359 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Renamed NAMES command to USERS command. The NAMES was named that
4362 due to historical reasons. Now it is renamed. Also, rewrote
4363 parts of the USERS command. The nickname list is not sent anymore
4364 by the server. Only Client ID and mode lists are sent in the USERS
4365 command. Changed this also to the protocol specification.
4367 The client now resolves the names and stuff after it receives
4368 the USERS list from the server when joining to the channel.
4370 * WHOIS and IDENTIFY commands has been changed to support multiple
4371 Client ID's per command. One can now search for multiple users
4372 in the network by sending only one WHOIS or IDENTIFY command.
4373 Changed the code and the protocol specifications.
4375 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4376 uses silc_server_command_whois_parse to parse the request. */
4378 * If normal server, do not parse the WHOIS and IDENTIFY requests
4379 before sending it to the router. Saves some time.
4381 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Fixed JOIN command on client library. Wrong number of arguments
4384 used to crash the client.
4386 * Added silc_server_channel_has_global function to check whether
4387 channel has global users or not.
4389 * Added silc_server_channel_has_local function to check whether channel
4390 has locally connected clients on the channel.
4392 * The silc_server_remove_from_one_channel now checks whether the
4393 channel has global users or not after given client was removed from
4394 the channel. It also checks whether the channel has local clients
4395 on the channel anymore. If it does not have then the channel entry
4396 is removed as it is not needed anymore.
4398 * The silc_server_notify now checks on JOIN notify whether the joining
4399 client is one of locally connected or global. If it is global then
4400 the channel has now global users on the channel and that is marked
4401 to the channel entry. Also, it now saves the global client to
4402 global list who is joining and JOINs it to the channel. This is
4403 for normal server, that is.
4405 Changed silc_server_send_notify_on_channel,
4406 silc_server_packet_relay_to_channel and
4407 silc_server_packet_send_to_channel check if we are normal server
4408 and client has router set (ie. global client) do not send the
4409 message to that client, as it is already routed to our router.
4411 * Implemented LEAVE notify type handling in silc_server_notify
4414 * Tested LEAVE command in router environment successfully. Tested
4415 with two routers, two servers and two clients.
4419 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4421 * Implemented SIGNOFF notify type handling in silc_server_notify
4424 * silc_server_remove_id now removes the client entry from all channels
4425 it has joined and thusly sends SIGNOFF notify type.
4427 * Rewrote the NAMES list generation in server by removing two excess
4428 loops. The lists are created now inside one loop.
4430 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * silc_server_remove_channel_user checks now also global list
4433 for channel and client.
4435 * silc_server_new_channel_user checks now both local and global
4436 list for channel and client. Fixed a bug in client id decoding.
4437 Used to decode wrong buffer.
4439 * silc_server_channel_message checks now both local and global
4440 list for channel entry.
4442 * Tested channel joining (hence JOIN) in router environment
4443 successfully. Tested with two routers, two servers and two
4446 * Tested channel message sending in router environment successfully.
4448 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Added silc_server_save_channel_key into server.[ch] to save the
4451 received channel key in Channel Key payload processing. It is
4452 also used in JOIN command reply handling.
4454 Equivalent function silc_client_save_channel_key added into
4455 client.[ch] into client library.
4457 * Changed JOIN command reply to send information whether the channel
4458 was created or not (is existing already) and the channel key
4459 payload. Changed protocol specs accordingly.
4461 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4462 the request was sent by ID and not by nickname. Crashed on
4465 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4468 now correctly save the received data.
4470 * silc_server_free_sock_user_data now notifies routers in the
4471 network about entities leaving the network.
4473 At the same time implemented functions silc_server_remove_id
4474 and silc_server_send_remove_id to receive and send REMOVE_ID
4475 packets. The packet is used to notify routers in the network
4476 about leaving entities. The ID removed will become invalid in
4479 * Added function silc_idlist_del_server into server. Removes and
4480 free's server entry from ID list.
4482 * silc_server_private_message function now checks, if we are router,
4483 that the destination ID really is valid ID, naturally.
4485 * In router when NEW_ID packet is received (for new client) the
4486 hash of the Client ID is saved in the ID Cache but the
4487 client->nickname is set to NULL, instead of putting the hash
4490 IDENTIFY command now also checks that client->nickname must be
4491 valid. If it is not if will request the data from the server who
4492 owns the client. Added new function
4493 silc_server_command_identify_check.
4495 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4496 to set the command to already allocated Command Payload.
4498 * Tested private message sending in router environment with two
4499 routers, two servers and two clients. Fixed minor bugs and now
4502 * Fixed segfault from client's NAMES command. Used to crash if
4505 * Forwarded packets must not be routed even if it is not destined
4506 to the receiver. Changed server code comply with this.
4508 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Added `require_reverse_mapping' boolean value to ServerParams
4511 structure. If TRUE (not default) the server will require that
4512 the connecting host has fully qualified domain name.
4514 If the reverse mapping is not required and hostname could not be
4515 found the IP address is used as hostname.
4517 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Implemented version string checking to both client and server.
4520 The check is incomplete currently due to the abnormal version
4521 strings used in development version of SILC.
4523 * Changed all command functions in server to use the new
4526 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Changed char *data to unsigned char *data in ID Cache system to
4529 support binary data as ID Cache data. Changed code to support
4530 binary data in lib/silccore/idcache.c.
4532 * Renamed silc_server_packet_relay_command_reply to
4533 silc_server_command_reply as it is normal packet receiving
4534 function. Rewrote the function to accept command replys for
4535 servers and not only for clients.
4537 * Mark remote router always as registered server if we are connecting
4538 to it. Otherwise, commands sent by the router to us are ignored.
4540 * All ID List find routines now returns the ID Cache Entry pointer
4541 as well if requested.
4543 * WHOIS command works now in router environment, tested with two
4544 routers, two servers and two clients.
4546 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4547 in router environment (as it is almost equivalent to WHOIS) but
4548 hasn't been tested thoroughly. Added new functions:
4550 silc_server_command_identify_parse
4551 silc_server_command_identify_send_reply
4552 silc_server_command_identify_from_client
4553 silc_server_command_identify_from_server
4555 * Disabled route cache adding because adding two different ID's with
4556 same IP replaces the old cache entry thus giving wrong route.
4557 The entry->router->connection is always the fastest route anyway
4558 so route cache may not be needed. Of course, new routes maybe
4559 established after receiving the ID when the entry->router->connection
4560 might not be anymore the most optimal.
4562 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Add route cache for received ID for fast routing.
4566 * Added silc_server_packet_route to route received packet on router
4567 that is not destined to us.
4569 * Renamed silc_server_get_route to silc_server_route_get.
4571 * Added id_string and id_string_len fields into SilcServer to
4572 include encoded ServerID for fast comparing without excess
4573 encoding of the ID's.
4575 * Cleaned up WHOIS command on server side. Added following static
4578 silc_server_command_whois_parse
4579 silc_server_command_whois_check
4580 silc_server_command_whois_send_reply
4581 silc_server_command_whois_from_client
4582 silc_server_command_whois_from_server
4584 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4585 arguments in command replies. All command functions should be
4586 updated to use this macro.
4588 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Minor typo fixes on command reply handling on server.
4592 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added silc_server_command_add_to_channel internal routine to add
4595 the client to the channel after router has created the channel and
4596 sent command reply to the server.
4598 * Added generic silc_server_send_command to send any command from
4601 * Use static buffer with ID rendering instead of duplicating data.
4603 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Fixed a channel user mode bug when joining to a channel server gave
4606 everybody channel founder rights, oops.
4608 * We mark ourselves as the router of the incoming server connection
4609 if we are router ourselves. This way we can check in some packet
4610 sending functions whether it is locally connected server. For
4611 incoming router connections we put NULL.
4613 * For router sending packets locally means now always sending the
4614 packet cell wide; to local clients and local servers. For normal
4615 server sending packet locally means sending it to only local
4618 * Fixed the JOIN command to really work in router environment. If the
4619 channel is created it is always created by the router. Router is
4620 also responsible of making the initial joining to the channel,
4621 sending JOIN notify to the sending server and distributing
4622 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4623 does not exist server doesn't do anything else but forward the
4624 command to the router which performs everything.
4626 * Added silc_server_send_channel_key function to send the Channel Key
4629 * Added silc_server_create_channel_key to create new channel key. The
4630 channel key is now re-generated everytime someone joins or leaves
4631 a channel, as protocol dictates. Note: channel->key_len is the
4634 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4637 packet_receive.[ch] to separate packet sending and receiving
4638 routines. The server.[ch] now includes everything else including
4639 actual packet processing (writing and reading data) and other
4642 Renamed silc_server_private_message_send_internal to
4643 silc_server_send_private_message. The routine is still though
4644 used only to relay private messages as server does not send
4645 private messages itself.
4647 Renamed silc_server_new_channel to silc_server_create_new_channel
4648 and added new function sicl_server_new_channel that handles the
4649 incoming New Channel packet. Added also new sending function
4650 silc_server_send_new_channel to send New Channel Payload.
4652 * Added new function silc_server_notify to process incoming notify
4653 packet to the server/router. Server may then relay the notify
4654 to clients if needed.
4656 * Added new function silc_server_new_channel_user to process incoming
4657 New Channel User packet. Router will redistribute the packet and
4658 send JOIN notify to its local clients and locally connected servers
4659 if needed. Normal server will send JOIN notify to its local client
4660 on same channel when received this packet. Added also corresponding
4661 sending function silc_server_send_new_channel_user to sent the
4664 * Added boolean route argument to send_notif_to_channel and
4665 packet_send_to_channel functions to attempt to route the packet
4666 if it is TRUE and send only locally if it is FALSE.
4668 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * silc_server_replace_id now broadcasts the received replace ID
4671 packet if it is not broadcast packet already. The router must
4672 broadcast to inform other routers about changed ID.
4674 * Added backpointer to server's router into SilcServer context in
4675 silcd/server_internal.h.
4677 * Fixed silc_server_packet_broadcast to send correct broadcast
4680 * The channel key is now distributed to the local client as soon
4681 as it is received from the router (in router environment) so that
4682 no other packet may be sent for the channel until client has
4685 * silc_server_remove_channel_user now broadcasts the received
4686 Remove Channel User packet if it is not broadcast packet already.
4687 The router must broadcast to inform other routers about removed
4690 * Added users field into SilcPacketContext that is a reference count
4691 of the context. One can increase the reference count by calling
4692 silc_packet_context_dup which is now changed to just increase the
4693 reference count instead of duplicating the data. The reference
4694 count is decresed by calling silc_packet_context_free that will
4695 free the data after the reference count hits zero.
4697 For now on the packet context and everything allocated into it
4698 (including the raw packet from network) must be freed by calling
4699 the new silc_packet_context_free function. Added also new function
4700 silc_packet_context_alloc that must be used now to allocate the
4701 context. This also means that if a routine is asynchronous from
4702 silc_[client/server]_packet_parse_type the packet context must
4703 be duplicated by calling silc_packet_context_dup. Otherwise it
4704 gets free'd after silc_[client/server]_packet_parse_type returns.
4705 Also, one must remember that if packet is duplicated then its
4706 reference count must be decresed by calling the free function as
4707 many times as it was duplicated.
4709 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4710 from both client and server.
4712 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Made joining to a channel working in router environment.
4716 * Cleaned up JOIN command on server side and create function
4717 silc_server_command_join_channel internal routine to make the
4720 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Changed silc_command_pending list to SilcDList. Also, added
4723 `ident' field to SilcServerCommandPending structure to identify
4724 the reply and to call correct callback.
4726 Added silc_server_command_pending_check function to replace the
4727 corresnponding macro. The silc_command_pending list is not
4730 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4731 to set identifier to previously allocated Command Payload. It
4732 is used to set identifier for command when resending Command
4735 * Added silc_command_payload_encode_payload to encode Command
4736 Payload buffer from SilcCommandPayload structure.
4738 * Added silc_argument_payload_encode_payload to encode Argument
4739 payload buffer from SilcArgumentPayload structure.
4741 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Changed WHOIS command to support router connection on server side.
4744 The whois request is always sent to router unless the server is
4745 standalone server. After server has received the reply from the
4746 router will it send the reply to the client.
4748 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4749 broadcast received broadcast packet. The function is used only
4750 by router. The broadcast packet is always sent to the router's
4753 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4754 render given ID to printable string, for log files for example.
4756 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Made basic router to router connections working. At least they
4759 can now connect to each other but nothing really works the way
4760 they are supposed - yet.
4762 * Added new initiator token to RouterConnection configuration
4763 file in silcd/serverconfig.[ch]. It is used to tell whether we
4764 are the initiator to the remote router or whether we'll expect
4765 the other end to connect.
4767 * Moved registering of listener task to silc_server_init, hence
4768 the server starts listenning as soon as it is run, even if it
4769 does not have connections to other routers. Let's see how well
4772 * Changed default connection retry timeouts for more suitable in
4775 * Removed cipher and such arguments from silc_idlist_add_client
4776 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4777 Added new function silc_idlist_add_data to add the keys and stuff
4780 * Added SilcIDListData structure and added it to SilcClientEntry
4781 and SilcServerEntry as their first field in the structure. This
4782 way we can explicitly cast the ID entries to the SilcIDListData
4783 structure and get common data for the entries. In past, we had
4784 to first check what type of connection it is and then cast it to
4785 correct ID entry type. Now, we can directly cast the opaque
4786 pointer to the SilcIDListData (no matter what ID entry it actually
4787 is) and get the data needed.
4789 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4792 in some circumstances even if threre were timeout tasks, though not
4793 IO tasks, but tasks anyway. Now fixed.
4795 * Defined SilcServerConnection structure to hold connection specific
4796 stuff about directly connected servers and routers. The definition
4797 is currently in silcd/server_internal.h. I thought about having
4798 a bit more important role fro this struct but for now it is used
4799 only when connecting to other server (or router actually).
4801 * Added connecting retry support in server when connecting to
4802 router(s). The retry feature implement exponential backoff
4803 algorithm. Also, added SilcServerParams structure to hold default
4804 parameters for server. For now, it include these retry settings
4805 and are hard coded. After server is moded to be as Silc Server
4806 Library this structure will be more important.
4808 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Changed client librarys channel->clients table to SilcList and
4811 changed code accordingly.
4813 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Changed client's channel table to SilcList and changed code
4816 accordingly. Also changed SilcChannelClientEntry to include back-
4817 pointer to the channel so that client entry can use that structure
4818 as list as well and we have fast cross-reference to the channel.
4819 This change dramatically decreased the complexity of channel
4820 handling with client entry and vice versa (removed one extra
4821 loop when searching for channel entry from many functions).
4823 * Changed server->sim from table to SilcDList and changed code
4826 * NAMES command can now be used from user interface. It will show
4827 the user list on the channel, neatly.
4829 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4830 Code now saves realname of the user if it becomes available.
4832 * Renamed configure.in to configure.in.pre and made ./prepare
4833 script to automatically add correct version string to
4834 configure.in which it creates from configure.in.pre.
4836 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * NAMES command reply now shows users mode with the nickname when
4841 * Moved silc_client_ch[u]mode[_char] functions from
4842 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4843 place sucks, they are utility functions and should be in some
4846 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4848 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4851 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4855 * Added TRQ (efficient deque and list library) into lib/trq. This is
4856 a very good list library that is currently used in the SILC. Defined
4857 SilcList API over the library because I didn't like the API very
4858 much. See lib/trq/silclist.h for the API and examples of how to
4859 use the API. Fixed various places in the code to use the new
4860 SilcList API. The SilcList is meant for lists that has a structure
4861 already defined as a list. It is not suitable to add just some
4862 context to the list (in TRQ, the context is the list actually).
4864 So, I defined SilcDList that can be used for the purpose where
4865 predefined list structure does not exit. This can be used as
4866 such list. Now some context just can be added to the SilcDList.
4867 Currently this list is not used in the SILC just yet, though there
4868 are a lot places where this can replace dynamically allocated
4869 tables and I will fix these places, later, to use SilcDList.
4870 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4871 and use TRQ internally).
4873 Also fixed some annoying warning messages that the original TRQ
4874 code generated. Also minor changes to TRQ's Makefile.in.
4876 * Added support for querying by Client ID to both WHOIS and
4877 IDENTIFY commands into server, as required by the protocol.
4879 * Removed method function pointers from SilcBuffer structure. They
4880 weren't used to anything and just increased the context size for
4881 no good reason. This change also made silc_buffer_alloc and
4882 silc_buffer_free functions inline functions.
4884 * Disabled command flooding detection support until it's fixed so
4885 that it accepts commands in but does not execute them more than once
4888 * Added silc_net_localhost(), to return local hostname, into
4889 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4890 that must be initialized before calling silc_client_init.
4892 * Added new function: silc_server_send_notify_on_channels to send
4893 notify messages to all channels client has joined. It is assured
4894 that the message is sent only once per client.
4896 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4897 lib/silcutil/silcutil.[ch] as silc_format function. The new
4898 function is generic and is used by server as well, not only by
4899 the logging routines.
4901 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4902 the provided version string was not acceptable. Added new function:
4903 silc_ske_check_version into lib/silcske/silcske.h. The function
4904 must be implemented by the application (client or server) and it
4905 does not reside in the SKE library. The function checks the version
4906 string remote end sent.
4908 * Added back pointers (to opaque context and to SilcSocketConnection)
4909 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4911 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4912 duplicate packet context structure.
4914 * Changed `notify' client operation to send same arguments as client
4915 receives from server except for ID's. ID's are mapped to correct
4916 ID entry and that is returned. Also, if channel entry is not sent
4917 by server but the notify is for channel the channel entry is sent
4918 to application (otherwise application doesn't know that it is for
4919 channel (library gets it from packet's Destination ID)).
4921 * Added silc_client_remove_from_channels into client library to
4922 remove a client from all channels it has joined to. Used when
4923 received SIGNOFF notify from server. Added also new function
4924 silc_client_replace_from_channels to replace old ID entry with
4925 new ID entry on all channels. Used when received NICK_CHANGE
4928 * Fixed ID Cache list handling in silc_idlist_get_client in
4929 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4930 to get (or query) client by ID.
4932 * Updated TODO list.
4934 * Added connection authentication status message defined by the
4935 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4936 support for these into the code in client and server side.
4938 * Added generic function silc_client_send_command to send any command
4939 with variable argument list. Application should use this function
4940 to send commands if the command functions provided by the library
4941 does not suite for the application's user interface needs.
4943 * Added new `failure' client operation. Application is notified about
4944 received failure packet if client is executing a protocol. In this
4945 case the protocol's execution has failed.
4947 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4948 is required by the protocol.
4950 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4951 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4954 * Added status flag to SilcSKE object to indicate realtime status
4955 of the SKE protocol.
4957 * Application receives now exactly same command reply arguments as
4958 the library receives from server. However, if ID is received the
4959 corresponding ID entry is returned to the application (eg. Client
4960 ID is mapped to correct SilcClientEntry entry and that is returned).
4961 Changed command_reply client operation due to this change.
4963 * Changed all ID's in commands and in command replys as ID Payloads.
4964 Change affected both client and server side codes.
4966 All ID's sent in SILC network (with execption of ID's in SILC
4967 Packet header) are sent in ID Payload to support variable length
4970 * Server now notifies nick changes and notifies all clients on
4971 the channels about the new nickname (about the new Client ID,
4974 * Implemented CMODE command to change channel modes. Supports all
4975 channel modes defined by the protocol specs except ban and invite
4976 lists. (Also, private channel key mode is supported but support for
4977 setting private channel key in client is missing, thus, this mode
4978 has no effect on client side (except that server requires that the
4979 client uses private channel key and normal channel traffic does not
4982 Also, invite mode works per se, but INVITE command does not work
4983 yet correctly, so you can set channel as invite only channel but
4984 inviting clients to the channel does not work (it is yet to be
4985 thought what's the best way to do it).
4987 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4988 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4989 Implemented CUMODE command to change user's mode on the channel.
4990 Supports all modes defined by the protocol specs.
4992 * Added NAMES command reply to return users modes on the channel.
4994 * Removed unnecessary and slow ciphers from lib/silccrypt.
4996 * Set SO_KEEPALIVE option to connection sockets by default.
4998 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5000 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5001 redefined the Notify Payload into protocol specs.
5003 * Added silc_id_payload_parse_id to get ID directly from raw
5006 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5009 accept searching by Client ID as well.
5011 * Added support for LEAVE and SIGNOFF notify types in client library.
5013 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5014 to parse ID Payload from raw data.
5016 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Added flags parameter into silc_ske_assemble_security_properties
5019 function in lib/silcske/silcske.[ch].
5021 * Changed notify client operation to fit better for notify messages
5022 sent by server. The notify payload received from server is now
5023 passed to the application (after parsing it to SilcNotifyPayload).
5024 It is application's responsibility to retrieve the arguments
5025 from the payload and show the message the way it wants. The message
5026 sent by server is implementation specific.
5028 * Changed public keys to comply with the protocol specification.
5029 Old public keys are not supported anymore and are not compatible.
5031 * Removed nickname from Channel Payload as the latest draft removed
5032 it. The client must resolve the nickname from the NAMES command
5033 reply received when it joined the channel.
5035 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5037 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Fixed some errors in protocol specification drafts.
5041 * Created lib/silccore/silcnotify.c to implement Notify Payload
5042 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5043 generic payloads described by protocol specifications. The file
5044 includes implementations for ID Payload and Argument Payload.
5046 * Changed Command Payload implementation to use the new Argument
5047 Payload. Changed command_xxxx_payload to command_payload_xxxx
5048 to comply with SILC coding conventions.
5050 * Added suppport for Argument Payload handling in Notify Payload
5051 implementation as protocol requires it. Added the new support
5052 into server and client lib as well.
5054 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Added support for multiple nicknames on same channel. [n] is
5057 added locally to the nickname if there are more than one same
5058 nicknames on the channel.
5060 * Server now sends all nicknames that matched WHOIS request.
5061 Client also shows the list received from server.
5063 * Added TOPIC command to client side. User can now set and show
5064 current topic on channel.
5066 * Added MOTD command to client and server. Also, server sends the
5067 motd when client connects to the server.
5069 * Changed version strings to comply ISO 8601.
5071 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Fixed protocol error handling in client library. It should now
5074 cope even if the SKE fails for some reason.
5076 * Made new protocol specification drafts for submitting to IETF.
5078 * Implemented TOPIC command to server in silcd/command.c.
5080 * Added two new notify types into lib/silccore/silcnotify.h:
5081 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5082 notify nickname change and topic setting/change on a channel.
5084 * API change of command_reply operation in client library. The
5085 application gets now the status type received from server as well.
5087 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5091 * Cras fixed and optimized the packet handling even further and
5092 it should work now. Minor change to the prototype of function
5093 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5095 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added new function into lib/silcutil/silcschedule.[ch]:
5098 silc_schedule_with_fd to select() a specified fd. The function
5099 returns after timeout expires or data arrives or goes. The
5100 function is used by packet routines to wait that all data is
5101 received from network.
5103 * Fixed data reading from network in lib/silccore/silcpacket.c.
5104 The code now assures that all data is read from the fd and then
5105 continues packet processing. This was a bug fix since the code
5106 used to drop some data in some circumstances.
5108 * Added new function into lib/silcclient/client.[ch]:
5109 silc_client_start_key_exchange to start key exchange after
5110 connection has been established to server. The code internally
5111 now uses this funtion but its main purpose was to provide it
5112 for applications that perform their own connecting. After
5113 application has created a connection it merely calls this
5114 function to start the key exchange between client and server.
5115 The library takes care of everything else after that.
5117 Updated also lib/silcclient/README to explain the usage of
5120 * Do not send to application information that connection has
5121 been established. Application gets notified it by connect
5124 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Applied cras's patch to add silc_schedule_one function. The
5127 function runs scheduler once and returns.
5129 * Fixed the scheduler after cras messed it up. The timeout
5130 handling works now as it's supposed to work.
5132 * Added into lib/silccore/ silcnotify.h to include notify
5133 message types support. Changed silc_server_send_notify*
5134 functions, in server.[ch], to support those new notify types.
5135 Added the support for the notify types into client library,
5136 as well. Added new notify client operation into ops.h in
5139 * Changed silc_server_packet_send_to_channel to send normal
5140 packets instead of just channel message packets. The function
5141 is now used to send the notify packets to channels. It is not
5142 used to send channel message packets anymore, as server never
5145 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5146 va_arg()s as it seems to require it nowadays. I guess, if SILC
5147 is compiled with older va_arg() the new code should work anyway.
5149 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Splitted core library. Core library (lib/silccore) includes
5152 now only SILC protocol specific core (and common) components.
5153 Created new utility library (lib/silcutil) that includes more
5154 generic purpose stuff. The stuff for util library was taken
5155 from the old core library. This was minor and easy split.
5157 * Created SILC Client Library (lib/silcclient) that includes
5158 implementation of the SILC client without user interface. This
5159 was major move from silc/ directory. The code has been changed
5160 so that it is transparent towards the user interface. The
5161 silc/ directory includes now the same user interface as before
5162 and it uses the new client library. Read lib/silcclient/README.
5163 Basicly, the client library performs everything else related
5164 to SILC except user interface handling. Also, configuration
5165 files are considered to be part of user interface and library
5166 does not handle them.
5168 This change also changed a lot of structures, function naming etc.
5169 Most important change was that SilcClientWindow object was
5170 renamed to SilcClientConnection in the client library. Created
5171 also new file lib/silcclient/ops.h. Also added new files
5172 silc/local_command.[ch] and silc/client_ops.[ch].
5174 All these changes were made to make it easier for user interface
5175 designers to create what ever user interface for the SILC client
5178 It is also expected that the server will be moved to lib
5179 directory as well and SILC Server Library will be created;
5180 sometimes in the future.
5182 * Removed Local commands from lib/silccore/silccommand.h as
5183 they are application specific and new client library does not
5184 handle any of those anymore.
5186 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5187 old client implementation in silc/.
5189 * Added support for callback functions in SILC_LOG_* macros.
5190 Application can now set its own callbacks that will be called
5191 instead of using the default functions that will always print
5192 the debug messages to stderr (or stdout). Also, debugging can
5193 now be disabled by setting silc_debug to FALSE and re-enabled by
5194 setting it to TRUE. Note, that logging will still work even
5195 if debugging is disabled.
5197 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5198 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5199 silc_log_reset_debug_callbacks.
5201 * To enable debugging in silc client one must give now -d
5202 option on command line.
5204 * Changed silc_schedule_init to automatically allocate task queues
5205 if they are not allocated before calling it.
5207 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added GMP 3.1 into math library.
5211 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5214 a channel in SILC network. The packet is used by servers and
5215 routers to notify other routers that user has left a channel.
5216 This little feature was missing until now. Added the feature
5217 to protocol specification as well.
5219 Added functions: silc_server_send_remove_channel_user and
5220 silc_server_remove_channel_user into server.[ch].
5222 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5223 lib/silccore/silcpacket.h. However, they are not implemented
5226 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Fixed joining to a channel and sending channel messages
5229 between server and router. The channel message sending should
5230 now work inside a cell.
5232 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Fixed the private message sending between server and router.
5235 The private message sending should now work inside a cell.
5237 * Added silc_server_replace_id into server.[ch] to replace
5238 existing ID in the SILC network.
5240 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5241 and silc_idlist_replace_server_id into idlist.[ch] in server.
5243 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Fixed the server to server connections. Server can again now
5246 connect to router. Router to router connections probably does
5249 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Added dynamic protocol registering support. Now protocols can
5252 registered and unregistered on the fly. Patch by cras.
5254 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added lib/contrib directory to hold routines that some platforms
5257 don't have but are needed by SILC.
5259 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5260 into lin/contrib to provide getopt() and getopt_long() for
5261 those who don't have it.
5263 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Added AWAY command to client. When away message is set and
5266 client receives a private message packet the client automatically
5267 replies to the sender with the away message.
5269 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5270 bug seemed to be the cause of recent problems when compiling
5273 * Added version detection support to SKE protocol specification
5274 and added the new changes to the SKE implementation as well.
5275 There were other minor changes in the SKE protocol as well.
5277 Many changes in lib/silcske/silcske.[ch] and in
5278 lib/silcske/payload.[ch].
5280 * Added ^U functionality, clear input line. Patch from cras.
5282 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Mainly small bugfixes on core library. Fixed some debugging
5285 logging and buffer overflow in silclog.c.
5287 * Updated config.sub and config.guess on the distribution tree.
5289 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Added command lagging support in server. Client may execute
5292 commands now only once in two seconds.
5294 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Optimized packet reception. MAC computation and checking is now
5297 also more optimized. A lot previously duplicated code is now
5298 used as generic by both client and server.
5300 * Fixed key pair generation in clientutil.c
5302 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Added into lib/silccore/silcbufutil.[ch] new function;
5305 silc_buffer_realloc.
5307 * Moved generic packet sending/encryption functions to
5308 lib/silccore/silcpacket.[ch] from client and server. Some
5309 rewriting of the functions.
5311 * Moved all generic packet reception/decryption functions to
5312 lib/silccore/silcpacket.[ch] from client and server. The
5313 packet processing is now much cleaner in both client and server.
5314 These were major changes in both client and server.
5316 * Created many common functions in server to do packet sending.
5317 Previously code were duplicated a lot, this has been removed
5320 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Rewrote major parts of the ID cache system. Don't know
5323 whether it is better now or not but at least the API is more
5326 * Major rewrite on ID cache stuff on client because of the ID
5327 cache API changes. Added idlist.c to client.
5329 * Also major rewrite on ID cache stuff on server as well.
5330 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5331 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5332 in hand, instead they are all put into the ID cache system now.
5333 All server_idlist_* routines uses ID cache now instead of
5334 traversing its own lists (those lists does not exist anymore).
5335 SilcIDList though still exists. Also, SilcXXXEntry's are
5338 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Finally made the SKE implementation compliant to the protocol
5341 specification. All mp integers are now binary encoded as
5342 opposed being HEX encoded.
5344 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5347 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5348 functions: silc_[encode/decode]_pem. Also added function
5349 silc_encode_pem_file to PEM encode with newlines ('\n') for
5352 * SILC public keys are now encoded either PEM or binary. Same
5353 option is for private keys as well. By default private keys
5354 are binary encoded and public keys PEM encoded. Silly HEX
5355 encoding were removed.
5357 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5358 function to create fingerprints.
5360 * Fixed a bug in SHA1; does not change the original data anymore.
5362 * Partly implemented INFO command on client and server side.
5363 Fixed CLEAR command. Changes to SERVER command; show current
5364 server(s) when giving command without arguments. Added
5365 VERSION command to client.
5367 * Added check to server that unregistered connections cannot
5368 execute commands (unless it is specificly allowed).
5370 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * Fixed screen refresh.
5374 * Fixed channel joining bug from client. On some circumstances
5375 client tried to join to a channel it had already joined.
5377 * Added public key verification process into client's protocol.c.
5378 The client now verifies the public key from user and saves
5379 it into ~./silc/serverkeys/ directory.
5381 Added into: clientutil.[ch]: silc_client_verify_server_key.
5383 * Changed SKE protocol's silc_ske_initiator_finish function
5384 to accept callback function that verifies the received public
5385 key. Removed old silc_ske_verify_public_key function.
5387 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5390 silc_pkcs_private_key[_data]_set.
5392 * Made the password and public authentication more cleaner in
5393 server's protocol.c.
5395 * Removed historic and obsolete protocol `channel_auth' from
5396 both client and server.
5398 * Removed wrong way of sending command status messages from
5399 server to client in server's command.c. The old way violated
5400 protocol specification.
5402 Changes to silccore/silccommand.[ch]: removed
5403 silc_command_encode_status_payload -> not needed anymore,
5404 changed silc_command_encode_payload_va to accept extra
5405 argument on variable argument list. The argument type must
5406 now be provided to the function. Also, added new function:
5407 silc_command_encode_reply_payload_va which is same as
5408 normal command_encode_payload_va except command status type
5409 is provided as extra argument.
5411 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Added ~./silc directory handling. The directory includes the
5414 public and private keys for the client.
5416 Added silc_client_check_silc_dir, silc_client_create_identifier
5417 and silc_client_load_keys.
5419 * Implemented SILC protocol compliant public key. Added public
5420 and private key saving to and loading from files.
5422 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5423 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5424 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5425 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5426 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5428 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5429 silc_pkcs_load_[public/private]_key.
5431 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Added silc_server_get_route (route.[ch]) to get connection
5434 data for the fastest route for given ID.
5436 * Implemented INVITE command on client and server. The command
