1 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the backup router adding and getting interfaces
4 in the server. The router that will be replaced by the
5 specified backup router is now sent as argument. Affected
6 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
9 * Added silc_net_addr2bin_ne to return the binary form of
10 the IP address in network byte order. Affected files
11 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
13 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
15 * Check for existing server ID in silc_server_new_server
16 and in silc_server_connect_to_router_final and remove the
17 old entry if it exists. Affected file silcd/packet_receive.c,
20 * Send the channel message always to only one router, either
21 in upstream or downstream. Affected file is
24 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
26 * Wrote the definition of the backup resuming protocol to the
27 protocol specification.
29 * Removed one redundant channel key generation from normal
30 server during joining procedure. Removed one redundant
31 channel key sending from server to router during joining
32 procedure. Affected file silcd/command.c.
34 * Made minor bugfixes to the backup router resuming protocol.
35 Affected file silcd/server_backup.c, server.c.
37 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Added --disable-asm configuration option. Affected files
40 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
43 * Implemented the backup resuming protocol that is used to
44 resume the primary router position in the cell after the
45 primary router comes back online. Affected files
46 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
47 and silcd/server_util.[ch].
49 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Sleep two (2) seconds after sending QUIT command to server.
52 Affected file lib/silcclient/command.c.
54 * Assure that if outgoing data buffer is pending do not force
55 send any data. Affected file silcd/packet_send.c.
57 * Assure that if outgoing data buffer is pending do not force
58 send any data. Affected file lib/silcclient/client.c.
60 * Implemented the backup router support when the primary router
61 goes down. The servers and routers can now use the backup
62 router as new primary router without loosing connectivity.
64 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
66 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
67 in the server to indicate disabled entry. All data read
68 from the connection will be ignored and no data is sent
69 for entry that is disabled. Affected files are
70 silcd/idlist.h, silcd/server.c.
72 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
74 * Created SFTP client and server test programs in the
75 lib/silcsftp/tests directory.
77 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
79 * Implemented memory filesystem (virtual filesystem) for
80 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
83 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Implemented the SFTP (SSH File Transfer Protocol) to the
86 lib/silcsftp. It includes SFTP client and SFTP server
89 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
91 * Moved lib/silccore/silcprotocol.[ch] to the
94 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
95 take variable argument list pointer as argument. Affected
96 file lib/silcutil/silcbuffmt.[ch].
98 * Added silc_buffer_set function that is used to set data
99 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
100 Affected file lib/silcutil/silcbuffer.h.
102 * Changed various routines in the core library to use the new
103 silc_buffer_set instead of allocating new buffer only for
106 * Added 64-bit value formatting and unformatting support to the
107 silc_buffer_[un]format routines. Affected file is
108 lib/silcutil/silcbuffmt.[ch].
110 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
111 to includes/bitmove.h.
113 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
115 * Fixed channel user mode saving in client library. Affected
116 file lib/silcclient/command[_reply].c.
118 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Defined the file transfer to the SILC Protocol. Added
121 new packet type SILC_PACKET_FTP and defined File Transfer
122 Payload. The mandatory file transfer protocol is SFTP
123 (SSH File Transfer Protocol). Affected file in addition
124 of the internet draft is lib/silccore/silcpacket.h.
126 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
127 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
128 is used as part of backup router protocol when the primary
129 router of the cell is back online and wishes to resume
130 the position as primary router.
132 * Redefined the MAC generation keys in the protocol. The
133 same key is not used anymore in both direction. Both
134 direction will now use different keys for sending and
135 receiving. This fixes a potential security flaw. This
136 change causes incompatibilities in the protocol.
138 * Redefined also the MAC computation from the packet.
139 An packet sequence number is now added to the MAC
140 computation. This prevents possible replay attacks against
141 the protocol. This change too causes incompatibilities
144 Added `sequence' field to the SilcPacketContext to hold
145 the current sequence number for the packet.
147 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
149 * Added `created' field to the SilcIDListData in the file
150 silcd/idlist.h to indicate the time when the entry was
153 * Added `created' field to the SilcChannelEntry too. Affected
156 * Added `creation_time' aguments to all the announcement functions
157 in the server. If it is provided then only the entries that
158 was created after the provided time frame are actually
159 announced. Affected file silcd/server.[ch].
161 * The protocol says that the Channel ID's IP address must be
162 based on the router's IP address. Added check for this in
163 the silc_server_new_channel when processing incoming New Channel
164 Payload. Affected file silcd/packet_receive.c.
166 * Print out the correct version with --version in SILC client.
167 Affected file irssi/src/silc/core/silc-core.c.
169 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
171 * Fixed WHOWAS command to check for completnes of the client
172 entry always, not just when the command is coming from client.
173 Affected file silcd/command.c.
175 * Added new function silc_server_packet_queue_purge to purge the
176 outgoing data queue to the network. After the function returns
177 it is guaranteed that the outgoing packet queue is empty.
178 Affected file silcd/packet_send.[ch].
180 * Purge the outgoing packet queue in the rekey protocol's final
181 callback to assure that all rekey packets go to the network
182 before quitting the protocol. Affected file silcd/server.c.
184 * Added silc_client_packet_queue_parse as similar function as
185 in server to the client library. The affected file is
186 lib/silcclient/client.c.
188 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Splitted silcd/server.c and created silcd/server_util.[ch]
191 for utility functions.
193 * Added new socket flag SILC_SF_DISABLED to indicate that the
194 connection is open but nothing can be sent to or received from
195 the connection. Affected file lib/silcutil/silsockconn.[ch].
196 The checking for disabled socket is checked in the low level
197 silc_socket_write and silc_socket_read functions.
199 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
201 * Allow only nicknames and channel names that fits into the
202 7-bit unsigned char ASCII set. Affected file silcd/command.c.
204 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
206 * When processing JOIN command reply in server check that if
207 the channel exists in our global list we'll move it the local
208 list. Affected file silcd/command_reply.c.
210 * Fixed the check whether client is joined on the channel already
211 in JOIN command. Affected file lib/silcclient/command.c.
213 * Fixed the JOIN command reply to check whether the channel
214 already exists. Affected file lib/silcclient/command_reply.c.
216 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Added silc_ske_status_string to map the SKE error numbers
219 to readable strings. The affected files are
220 lib/silcske/silcske[_status].[ch].
222 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
224 * Do not show the private channels on the WHOIS channel list
225 as it is not allowed by the protocol. The affected file is
228 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
230 * Assure that the packet length digged from the actual packet
231 is something sensible in the silc_packet_decrypt_rest_special
232 in lib/silccrypt/silcpacket.c.
234 * Free and NULL the allocated pointer in silc_hmac_alloc if
235 the HMAC allocation fails. The affected file is
236 lib/silccrypt/silchmac.c.
238 * Print the selected security properties to the log files in
239 the server. Affected file silcd/protocol.c.
241 * Add SKE's reference counter even if calling the completion
242 callback manually. Otherwise it goes negative, although it
243 does not cause any problems. The affected file is
244 lib/silcske/silcske.c.
246 * Remove the client entry with short timeout after giving the
247 KILL command. Affected file lib/silcclient/command.c.
249 * Fixed to send error reply in WHOIS and IDENTIFY commands in
250 case all found clients are already disconnected (WHOWAS would
251 found them) in the server. Affected file silcd/command.c.
253 * Update the last_receive (time of last data received) to be
254 updated only when received private or channel message so that
255 the idle time showed in WHOIS makes more sense.
257 * Added boolean field `valid' in to the SilcClientEntry in the
258 client library to indicate whether the entry is valid or not.
259 This fixes the nickname change bug on channel when changing
260 the nickname to be same than the old (like nick to Nick) the
261 nickname formatter doesn't set the new nick anymore to Nick@host.
262 Affected file lib/silcclient/idlist.[ch].
264 * Now actually fixed the nickname changing on disconnection.
265 Added new function silc_change_nick to the Irssi SILC Client.
266 Affected file irssi/src/silc/core/client_ops.c,
267 irssi/src/silc/core/silc-nicklist.[ch].
269 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
271 * Check that the public key exists in the GETKEY command before
272 trying to encode it. Affected file silcd/command.c.
274 * Print some notifications on received public keys with GETKEY
275 command in the Irssi SILC Client. Affected files are
276 irssi/src/fe-common/silc/module-formats.[ch],
277 irssi/src/silc/core/client_ops.c.
279 * Use IDENTIFY command to resolve the server information in the
280 GETKEY command instead of INFO command. Affected file
281 lib/silcclient/command.c.
283 * All command reply functions in the client library now calls
284 the pending command reply callbacks even if an error has
285 occurred. The server has done this a long time and now it was
286 time to move the client library to this as well. Now all
287 errors can be delivered back to the pending command reply
288 callbacks if necessary. Affected files are
289 lib/silcclient/command[_reply].[ch].
291 * Change the nickname on disconnection back to the username
292 because in reconnect the server will enforce it to it anyway.
293 Affected file irssi/src/silc/core/silc-servers.c.
295 * Fixed a config file parsing bug in the Irssi SILC client.
296 Affected file irssi/src/silc/core/clientconfig.c.
298 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
300 * When printing the channel mode on JOIN, verify that the
301 channel key and channel's HMAC are valid. Affected file
302 irssi/src/silc/core/client_ops.c.
304 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
306 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
307 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
308 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
310 * Removed channel key rekey task deleting from the function
311 silc_server_save_channel_key. Affected file silcd/server.c.
312 Added explicit timeout task context instead that is used to
313 delete the task if we are registering a new task before the
314 new task has elapsed.
316 * When channel key rekey occurs the client library now saves
317 the old channel key for a short period of time (10 seconds) and
318 is able to use it in case some is still sending channel
319 messages encrypted with the old key after the rekey. Affected
320 file lib/silcclient/[idlist.h|client_channel.c].
322 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Added check to the silc_server_new_id_real to not accept
325 new ID if it is the sender's own ID. Affected file is
326 silcd/packet_receive.c.
328 * Assure that we do not announce ourself or the one we've
329 sending our announcements when we're router and are announcing
330 servers to our primary router. Affected file silcd/server.c.
332 * Fixed silc_server_command_identify_check_client to assemble
333 correct WHOIS packet. It send corrupted WHOIS packet and
334 caused problem with router to router connections. Affected
335 file silcd/command.c.
337 Fixed also silc_server_command_whois_check the same way
338 as for the IDENTIFY command.
340 * Added new SilcIDListStatus to the server in the SilcIDListData
341 structure. The status now includes the current status of
342 the entry (like registered, resolved etc.). Affected file
343 silcd/idlist.[ch]. Defined a bunch of different status types
344 as well. This replaced the old boolean registered field as well.
346 Added resolve_cmd_ident field to the SilcClientEntry structure
347 too so that if the entry is for example being resolved so
348 another command may attach to the same pending command reply
349 without requiring to resolve the same entry again. This concept
350 should optimize the WHOIS and the IDENTIFY resolving under
351 heavy load by taking away unnecessary resolving for entries
352 that are being resolved already.
354 Added support for adding multiple pending commands for one
355 command idenfier. Affected file silcd/command[_reply].[ch].
357 * Fixed WHOIS and IDENTIFY save to remove the cache entry
358 before deleting the data. Otherwise the hash table will have
359 freed data in comparison functions. Affected file is
360 silcd/command_reply.c.
362 * Fixed silc_idlist_replace_client_id to add the new entry to
363 the cache with NULL nickname. Otherwise there will be invalid
364 memory as the nickname after the nickname is freed. Affected
365 file silcd/packet_receive.c.
367 * Fixed the silc_idlist_get_clients_by_hash. The entries was
368 saved into wrong slots because the previous number of entries
369 was not taken into account. Affected file silcd/idlist.c.
370 Fixed same thing in silc_idlist_get_clients_by_nickname too.
372 * If we are router and we receive JOIN notify to a channel that
373 does not have any users then notified client is marked as the
374 channel founder, as it is it. The affected file is
375 silcd/packet_receive.c
377 * Added to the extended hash table API's table_del_*ext functions
378 the destructor as argument too, so that the caller can decide
379 which destructor to use or whether to use destructor at all.
380 Affected file lib/silcutil/silchashtable.[ch].
382 * Fixed ID Cache purging. It actually deleted the entries from
383 the hash table after the data was freed. The hash table ended
384 up comparing freed memory. The affected file is
385 lib/silccore/silcidcache.c.
387 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
389 * Fixed Irssi SILC client's KILL command's HELP syntax.
391 * The USERS command now resolves the detailed user information
392 if the userinfo field is missing. Affected file is
393 lib/silcclient/command_reply.c.
395 * Do not print error in silc_file_read if the read file does
396 not exist. Just silently return NULL. Affected file is
397 lib/silcutil/silcutil.c.
399 * Fixed the silc_log_output to not wine about NULL filename
400 and to not create some bogus " " filename. Affected file is
401 lib/silcutil/silclog.c.
403 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Fixed various printing bugs on the user interface in the
406 Irssi SILC Client. Minor changes that were forgotten from
409 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
411 * Fixed the configure.in.pre and the compilation and distribution
412 environment to support the new autoconf 2.52. That version is
413 now required to compile the CVS trunk.
415 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
417 * Renamed function silc_parse_nickname to silc_parse_userfqdn
418 to generally parse user@fqdn format strings. Affected file
419 lib/silcutil/silcutil.c.
421 * Added nickname_format and nickname_force_format fields to the
422 SilcClientParams structure. The first one defines the format
423 for the nicknames that the library will enforce if the receives
424 multiple same nicknames. The second one is boolean value and
425 can be used to force the library to always enforce the format
426 to the nicknames regardles whether there are multiple nicknames
427 or not. This configurable formatting was employed to flexibly
428 support accessing multiple nicknames from the user interface.
429 The userinterface can now set the nicknames to what ever format
430 they prefer. Affected file lib/silcclient/silcapi.h.
432 Added function silc_client_nickname_format to the file
433 lib/silcclient/idlist.c. It performs the nickname formatting.
435 Added new field `hostname´ to the SilcClientEntry context.
436 It holds the hostname of the client. Affected file is
437 lib/silcclient/idlist.h.
439 * Irssi SILC Client sets the nicknames in nick@hostn format.
440 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
441 irssi/src/silc/core/silc-core.c.
443 The WHOIS printing now also shows both the real nickname and
444 the formatted nickname so that user knows how to access the
445 user if there are multiple same nicknames cached. Affected
446 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
447 printing formatting too to take the hostname now as a separate
448 argument. The Affected file is
449 irssi/src/fe-common/silc/modules-formats.[ch].
451 * Changed the silc_client_get_clients_local to accept the formatted
452 nickname as argument. It accepts the real nickname too but the
453 formatted nickname can be used to find the true entry from
454 multiple entries. Affected file lib/silcclient/silcapi.h and
455 lib/silcclient/idlist.c.
457 * Added nickname_format_parse field to the SilcClientParams.
458 It is a callback function provided by the application to parse
459 the nickname out of the formatted nickname string. The library
460 calls it to get the nickname from the formatted string. Since
461 the application generally knows better the format of the nickname
462 string it parses it instead of the library, even though library
463 encodes the formatted string. If the callback function is not
464 provided then the library will use the string as is. The
465 affected file is lib/silcclient/silcapi.h.
467 * All the nickname strings passed to the client library in
468 commands are now expected to be formatted nickname strings.
469 If the command does not support the formatted nickname string
470 it will assume that the sent string is the actual nickname.
471 Affected file lib/silcclient/command.c.
473 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
475 * Added public key authentication support to OPER and SILCOPER
476 commands in the client library. Affected file is
477 lib/silcclient/command.c.
479 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
481 * Changed the get_auth_methdod client operation to be asynchronous.
482 It can be async if the application resolves the authentication
483 method from the server during the negotiation. Added new
484 SilcGetAuthMeth completion callback that the application will
485 call after resolving the authentication method.
487 Added function silc_client_request_authentication_method that
488 the application can use to resolve the authentication method
489 from the server. Added also SilcConnectionAuthRequest callback
490 that the library will call after the server has replied. The
491 application can call this function if it does not know the
492 current authentication method.
494 Affected files are lib/silcclient/client.c and
495 lib/silcclient/silcapi.h.
497 * The Irssi SILC client now automatically resolves the authentication
498 method incase any configuration information is not present (and
499 currently there never is). The affected file is
500 irssi/src/silc/core/client_ops.c.
502 * Fixed public key authentication from the client library.
503 Affected file lib/silcclient/protocol.c. Changed also the
504 protocol specification about the public key authentication in
505 the connection authentication protocol. The actual data to be
506 signed is now computed with a hash function before signing.
508 * Fixed the public key authentication from the server as well.
509 Affected file silcd/protocol.c.
511 * Removed the mlock()'s from the memory allocation routines.
512 Affected file lib/silcutil/silcmemory.c. The ./configure does
513 not check anymore for the mlock(). Affected file is
516 * Fixed USERS command in server to allow the execution of the
517 command for private and secret channels if the client sending
518 the command is on the channel. Affected file silcd/command.c.
520 * Fixed silc_client_get_clients_local to return the clients
521 count correctly. It could return wrong value. Affected file
522 lib/silcclient/idlist.c.
524 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
526 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
527 types. The assembler optimizations seemed not to like 64-bit
528 data types. The assmebler optimizations thus are now enabled
529 also for BSD systems as opposed to only enable them for Linux.
531 * Do not check for threads at all on BSD systems. Affected
532 file configure.in.pre.
534 * Removed -n and -h options from the Irssi SILC Client since
535 they are not used in silc.
537 * Fixed the prime generation to assure that the first digit
538 of the generated random number is not zero since our conversion
539 routines does not like number strings that starts with zero
540 digit. If zero digit is seen the random number is regenerated.
541 This caused some corrupted RSA keys when the zero first digit
542 was met. Affected file lib/silcmath/silcprimegen.c.
544 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Fixed WIN32 configuration in the ./configure script.
547 Fixed to include xti.h on environments that has it.
548 Patches by Carsten Ilchmann and andrew.
550 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
552 * Changed the silc_id_create_client_id to be collision
553 resistant. It is now assured that there cannot be created
554 two same client ID's. I suspect that some weird bugs in
555 the server were actually caused by duplicate Client IDs.
556 Affected file silcd/serverid.[ch]. A router receiving
557 new ID now also assures and informs the sending server
558 if the ID caused collision.
560 * Changed the silc_id_create_channel_id to also assure that
561 there are no collisions.
563 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Statement about ignoring the Mutual Authentication flag when
566 performing rekey with PFS was a bit misleading. It is ignored
567 if it was set in the initial negotiation, it cannot be even
568 set in the rekey. Fixed in the ke-auth draft. Started the
569 new versions of the protocol drafts in the doc/.
571 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
573 * Fixed a bug in silc_client_command_identify_save when saving
574 new channel information. The channel name was no duplicated
575 and caused crash on exit. Affected file is
576 lib/silcclient/command_reply.c.
578 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
580 * Fixed the getkey command handling in the server. Send just
581 empty OK reply to the sender if the key could not be fetched
582 (but everything else was ok, like the key just was not available).
583 Changed the public key parameter to optional in the protocol
584 specs so that empty OK reply can be sent. Affected file
587 Added a message to Irssi SILC client to tell to user if the
588 server did not return a public key.
590 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Fixed a channel key regeneration bug. It registered new
593 timeout tasks exponentially until all system resources were
594 used. Affected file silcd/server.c.
596 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Added the SILC Document generator to the scripts/silcdoc.
599 It can be used to generate the Toolkit Reference Manual out
600 of the source tree. Internally it will also use the RoboDoc
601 generator now imported in util/robodoc.
603 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
605 * Added couple of return's in rekey protocol if error orccurred
606 during the protocol. The execution must be terminated.
607 Affected file silcd/protocol.c. Also, terminate the protocol
610 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
612 * The client's Client ID was created initally from the wrong
613 nickname (it could have been in format nick@host) in the
614 silc_server_new_client. Affected file silcd/packet_receive.c
616 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
618 * Added some SILC_LOG_ERROR's to various error conditions
619 if client could not be added to ID cache. Affected files
620 silcd/packet_receive.c and silcd/server.c.
622 * When client's sock->user_data is freed, NULL also the
623 client->router and client->connection pointers. Added check
624 for these pointers being NULL to various places around the
625 code. Affected file silcd/server.c.
627 * Added client->data.registered == TRUE checks to various
628 places around the code to assure that unregistered client's
629 are not handled when it is not allowed. Affected file
632 * Added `bool registered' fields to all
633 silc_idlist_[server|client]_get_* routines to indicate whether
634 the fetched client needs to be registered or not. Affected
635 file silcd/idlist.[ch].
637 * Add your own entry as registered to the ID cache in the
638 server. Affected file server.c.
640 * Fixed a bug in silc_server_new_server. The SilcServer was
641 set as the new server's context instead of SilcServerEntry.
642 This naturally caused some weird bugs.
644 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
646 * Do not delete the channel rekey task when adding it
647 for in silc_server_create_channel_key.
649 * Changed the silc_server_create_channel_key to return
650 TRUE or FALSE to indicate the success of the channel key
653 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
655 * Fixed MSVC++ project files and added missing files to
656 Makefiles under win32/.
658 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Do not add TCP_NODELAY flag if the operating system
661 does not have it defined. Affected files are
662 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
664 * Fixed buffer overflow from Irssi SILC Client. Affected
665 file irssi/src/fe-common/core/themes.c.
667 * Fixed double free in client library in the file
668 lib/silcclient/client.c when disconnecting from server.
670 * Applied double free patch from cras to Irssi SILC client.
671 Affected files irssi/src/core/[modules/expandos].c
673 * Fixed the disconnection handling to Irssi SILC Client.
674 The application must call silc_client_close_connection
675 in ops->connect client operation in case of failure of
676 the connection. Affected file is
677 irssi/src/silc/core/client_ops.c.
679 * Do not set sock->protocol to NULL in the function
680 silc_client_close_connection after executing the protocol's
681 final callback since the sock might not be valid anymore.
682 Affected file lib/silcclient/client.c.
684 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Do not enable SILC_THREADS if the linking with libpthread
687 did not happen. Affected file configure.in.pre.
689 * Added notion to protocol specification that server must
690 verify the sent authentication payload with CMODE when
691 setting the channel founder key. Implemented it to the
692 server. Affected file silcd/command.c.
694 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
696 * Added _EXTRA_DIST SILC distribution variable to the
697 distributions file. It is used to conditionally add extra
698 files or directories to the specific distribution. Affected
699 files ./prepare, Makefile.am.pre and distributions.
701 Removed the `_' from the start of the distribution names.
704 * Added README.WIN32 for instructions to compile the Toolkit
707 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
709 * Fixed a double free in disconnection in the server. Affected
710 file is silcd/server.c.
712 * Fixed the lib/silcske/groups.c to work now also with GMP
713 MP library. The string conversion did not work when using
714 specific base and the base is indicated in the string as well.
716 * Created win32/ directory which now includes MSVC++ specific
717 stuff so that toolkit (DLLs) may be compiled with MSVC++.
718 It will appear only in the toolkit distribution
720 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Changed the key material distribution function in case when
723 the hash output is too short. The data is now concatenated
724 a bit differently than it used to. Made the change to the
725 SKE protocol specification.
727 * Added better GMP detection to configure.in.pre. A patch
730 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Fixed a minor bug in SKE that might cause some problem on
733 some platforms. Affected file lib/silcske/silcske.c.
735 * Added the cookie checking for initiator in the SKE. It checks
736 that the responder returns the sent cookie unmodified. The
737 affected file is lib/silcske/silcske.c. Added new SKE
738 error type INVALID_COOKIE that can be sent during the
739 negotiation. Fixed some memory leaks as well.
741 * Added the "invalid cookie" error message to Irssi SILC client's
744 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Added `task_max' field to the SilcClientParams to indicate
747 the maximum tasks the scheduler can handle. If set to zero,
748 default values are used. Affected file lib/silcclient/silcapi.h.
750 * Fixed memory leaks in silc_client_close_connection. Affected
751 file lib/silcclient/client.c.
753 * Added silc_client_del_client_entry to client library to free
754 all memory of given client entry. Affected file is
755 lib/silcclient/idlist.[ch].
757 * Added new functions silc_client_del_channel and
758 silc_client_del_server to delete channel and server entries.
759 Affected file lib/silcclient/[silcapi.h/idlist.c].
761 * Removed silc_client_del_client_by_id from silcapi.h.
763 * Fixed the INFO command to return the server's own info
764 correctly when querying by Server ID. Affected file is
767 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
769 * Removed the non-blocking settings in WIN32 code in the
770 silc_sock_[read/write] and added SleepEx instead. Affected
771 file lib/silcutil/win32/silcwin32sockconn.c. The availability
772 of input data is now checked with FIONREAD and ioctlsocket.
774 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
776 * Call silc_schedule_task_del_by_context in the
777 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
778 Affected file lib/silccore/silcprotocol.c.
780 * Call silc_protocol_cancel for active protocols in the
781 silc_server_close_connection if the funtion
782 silc_server_free_sock_user_data has not been called.
783 Affected file silcd/server.c.
785 * Generic tasks cannot be deleted using the del_by_fd
786 task deleting function since generic tasks does not match
787 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
789 * Added a notion to SILCOPER help file that the SILCOPER works
790 only on router server, not on normal server.
792 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Added for WIN32 support for the new scheduler as well.
795 Affected file lib/silcutil/win32/silcwin32schedule.c.
797 * Fixed the SHA1 implementation to work on various platforms.
799 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
802 API. It is part of the scheduler now. Everything else is
803 as previously but some functions has changed their names.
804 Checkout the lib/silcutil/silcschedule.h for the interface.
805 Updated all applications to use the new interface. Affected
806 files are lib/silcutil/silcschedule.[ch].
808 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
810 * Found a bug in the SKE implementation. The HASH value,
811 specified by the protocol, was not computed correctly. The
812 public key of the responder was not added to the computation
813 even though it is mandatory. Affected file lib/silcske/silcske.c.
814 This unfortunately causes incompatibilities with older
817 * Added WIN32 specific network init and uninit functions:
818 silc_net_win32_init and silc_net_win32_uninit to init and uninit
819 the Winsock2. Affected file lib/silcutil/silcnet.h and
820 lib/silcutil/win32/silcwin32net.c.
822 * Set the socket always to nonblocking mode on WIN32 after
823 reading data or writing data. Affected file is
824 lib/silcutil/win32/silcwin32sockconn.c.
826 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Fixed various compilation problems under WIN32. Affected
829 files lib/silcutil/win32/silcwin32thread.c and
830 lib/silcutil/win32/silcwin32schedule.c.
832 * Removed all _internal.h #includes from public header
833 files. Internal headers must never be included from
836 Removed also the lib/silcske/payload_internal.h file.
838 * All include files that may be needed (public and some others
839 included by the public headers) by application developers are
840 now copied to the ./includes directory. It does not copy any
841 internal headers. Affected file Makefile.defines.pre and all
842 Makefile.am's under lib/ and subdirs.
844 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Do not change the ~/.silc directory's permissions automatically.
847 Affected file irssi/src/silc/core/clientutil.c.
849 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Do not cancel the protocol in silc_server_close_connection
852 it might cause recursion. Now cancelled in the function
853 silc_server_free_sock_user_data. Affected file silcd/server.c.
855 * Fixed the silc_server_remove_clients_by_server to regenerate
856 the channel keys correctly finally. Added also new function
857 silc_server_remove_clients_channels to actually do it.
858 Affected file silcd/server.c.
860 * Fixed the silc_server_new_channel to not crash by giving
861 wrong router to the new channel. Affected file is
862 silcd/packet_receive.c.
864 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
867 which is given as argument to the silc_client_alloc now.
868 It can be used to configure the client and set various parameters
869 that affect the function of the client.
871 * The USERS command in server did not check whether the channel
872 is private or secret. Affected file silcd/command.c.
874 * Added new argument to the USERS command in protocol specification.
875 The USERS command now can take the channel name as argument
876 as well. Added support for this in client and server and
877 updated the protocol specs.
879 * Completed the GETKEY command in client. It can be now used
880 to fetch also servers public key not only some clients.
881 Affected files lib/silcclient/command[_reply].c.
883 * Added silc_client_get_server to return server entry by the
884 server name. Affected files lib/silcclient/silcapi.h and
887 * Redefined the IDENTIFY command in protocol specification to be
888 more generic. It now can be used to query information about
889 any entity in the SILC Network, including clients, servers and
890 channels. The query may be based either the entity's name
891 or the ID. Added support for this in both client and server.
893 Affected files silcd/command.c and lib/silcclient/command.c
896 * Optimized the WHOIS and WHOWAS commands in the server. Removed
897 the _from_client and _from_server functions. Affected file
900 * Added silc_client_get_channel_by_id_resolve to the file
901 lib/silcclient/silcapi.h to resolve channel information by
902 its ID. Added also silc_client_get_channel_by_id that
903 does not resolve it from the server.
905 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Added SilcServerEntry context into the client library
908 to represent one server. The INFO command now allocates
909 these to save the resolved server info. For now on the
910 client library will also keep information about servers,
911 connected and resolved with INFO.
913 The INFO command now allocates the SilcServerEntry context
914 and saves the server info there. The COMMAND_REPLY in
915 the INFO now returns the parameters to application in
916 same order as defined in the protocol specification.
918 The entries are cached in the client->server_cache.
920 * The INFO command is now issued after received the Client ID
921 from the server. Affected file lib/silcclient/client.c.
923 * The CMODE_CHANGE notify may now return also an SilcServerEntry
924 to the application as the mode changer might be server.
925 It is guaranteed that NULL is not returned anymore to the
926 application. Affected file lib/silcclient/client_notify.c.
928 The ID Type is now also passed to the application so that
929 it can check whether the returned entry is SilcClientEntry
932 Added new function silc_client_get_server_by_id to return
933 the server entry by ID. Affected files are the
934 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
936 * Do not create the channel in the Irssi SILC Client when issuing
937 the JOIN command but when received the sucessful JOIN command
938 reply. Otherwise the channel might get created even though we
939 could not join it. The Affected file is
940 irssi/src/silc/core/[silc-channels.c/client_ops.c].
942 * Fixed a channel joining bug in router. The router must also
943 check the channel modes, invite and ban lists etc. when serving
944 the JOIN command sent by normal server. Affected file is
945 silcd/command.c. The router now resolves the client's
946 information from the server who sent the JOIN command if it
947 does not know it, and processes the JOIN command only after
950 * Changed the SilcCommandCb to take new argument; void *context2.
951 Affected file lib/silccore/silccommand.h
953 The second argument in the command callbacks in the server now
954 includes the SilcServerCommandReplyContext if the command was
955 called as pending command callback from the command reply.
956 Otherwise it is NULL. When called as pending the status of the
957 command reply will be checked and if it was erronous the
958 error will be sent to the original sender of the command.
959 This way the client always receives the error messages even
960 though the server was actually the one who received the error
961 when it resent the command to router, for example. Affected
962 files silcd/command[_reply].[ch].
964 * Fixed sending WHOWAS command's error message to client if
965 the requested client could not be found. It was missing.
968 * Changed the CMODE and CUMODE commands reply arguments in the
969 protocol specification. The Channel ID is now sent in both
970 of the commands to identify the channel. Implemented this
971 new feature to the client and server. Affected files
972 lib/silcclient/command_reply.c and silcd/command.c.
974 * Made better checks for invite and ban lists in the JOIN
975 command in server. Affected file silcd/command.c.
977 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
979 * The server now performs the incoming host IP/DNS lookup
980 using the silc_socket_host_lookup and thus does not block
981 the server anymore. Affected file silcd/server.c.
983 * Completed the multi-thread support for SILC Scheduler in
984 the lib/silcutil/silcschedule.c.
986 * Fixed the configure.in.pre to detect the pthread correctly
989 * Fixed a deadlock in silc_task_queue_wakeup in the file
990 lib/silcutil/silctask.c.
992 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Added new function silc_schedule_wakeup that is used in
995 multi-threaded environment to wakeup the main thread's
996 schduler. It needs to be used when a thread adds a new task
997 or removes a task from task queues. After waking up, the
998 scheduler will detect the task queue changes. If threads
999 support is not compiled in this function has no effect.
1000 Implemented the wakeup mechanism to both Unix and WIN32
1001 systems. Affected files are lib/silcutil/silcschedule.[ch],
1002 lib/silcutil/unix/silcunixschedule.c and the
1003 lib/silcutil/win32/silcwin32schedule.c.
1005 * Added new function silc_task_queue_wakeup to wakeup the
1006 scheduler by the specified task queue. Affected file
1007 lib/silcutil/silctask.[ch].
1009 * The silc_socket_host_lookup_start now wakes up the scheduler
1010 after adding the timeout task. Affected file is
1011 lib/silcutil/silcsockconn.c.
1013 * The silc_socket_host_lookup is synchronous now if the threads
1014 support is not compiled in. However, the callback is still
1015 called asyncronously through the scheduler, anyway. Affected
1016 file lib/silcutil/silcsockconn.c.
1018 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * Added new function silc_socket_host_lookup to perform
1021 asynchronous IP and FQDN lookups for the socket connection.
1022 Affected files lib/silcutil/silcsockconn.[ch].
1024 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1027 that may or may not compile the mutex support in.
1029 Changed the silc_mutex_alloc interface. It allocates the
1030 mutex now to the sent pointer and returns TRUE or FALSE.
1032 Affected file lib/silcutil/silcmutex.h.
1034 * Wrote the SILC Task Queue interface to support multi-threads.
1035 Affected file lib/silcutil/silctask.[ch].
1037 * Wrote the SILC Scheduler to support multi-threads. Affected
1038 file lib/silcutil/silcschedule.c.
1040 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1043 in lib/silcutil/win32/.
1045 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Defined SILC Mutex API and SILC Thread API and implemented
1048 them for Unix. Affected files are
1049 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1050 lib/silcutil/unix/silcunixmutex.c and
1051 lib/silcutil/unix/silcunixthread.c.
1053 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Fixed the silc_server_remove_clients_by_server's channel
1056 key re-generation. The hash table handling was incorrect
1057 and would not work with many channels. Affected file is
1060 * Fixed some memory leaks around the server code.
1062 * Rewrote the silc_server_get_users_on_channel to support IPv6
1063 based Client ID's. Affected file silcd/server.c.
1065 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1066 specification. However, a separate document must be written
1067 to define the detailed signing procedure and the payload
1068 associated with the flag. Defined the flag to the
1069 lib/silccore/silcchannel.h as well.
1071 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1073 * Changed the dynamic tables to static size tables in the
1074 lib/silccrypt/silchmac.c.
1076 * Removed GCC dependencies from the code. A patch by cras.
1078 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Do not show the error "Error receiving packet bla bla"
1081 in server if it really was not an error (-2 means that reading
1082 is pending). Affected file silcd/server.c.
1084 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Fixed a possible crash in silc_server_remove_clients_by_server
1087 in silcd/server.c. Fixed there also some memory leaks.
1089 * Fixed the silc_idlist_replace_client_id. It could replace
1090 wrong key in the hash table. Affected file silcd/idlist.c.
1092 * Do not check whether there are global users on the channel
1093 if the channel->global_users is FALSE. Affected functions
1094 silc_server_remove_from_one_channel and
1095 silc_server_remove_from_channels in silcd/server.c. Also,
1096 do not check if the removed client is local as we can be
1097 sure that global client was not removed from the channel
1098 and checking for global users is not needed.
1100 * The silc_server_remove_clients_by_server now re-generates
1101 the channel keys correctly for those channels that had
1102 clients removed from them. Affected file silcd/server.c.
1104 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * Found the reason of random crashes in the server. We weren't
1107 ignoring the SIGPIPE signal (which can be sent in write())
1108 and it crashed the server. Affected file silcd/silcd.c.
1110 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Assure that sock->user_data is not NULL in the function
1113 silc_server_packet_send in silcd/packet_send.c.
1115 * Disconnect the remote connection if it could not be added
1116 to any ID lists in the server. The affected file is
1119 * Check in silc_server_packet_send[_real/dest] that the
1120 socket is not disconnecting and ignore the data if it is.
1121 Affected file silcd/packet_send.c.
1123 * Define inline to __inline on native WIN32 compilation.
1124 Affected file includes/silcwin32.h.
1126 * Added some explicit type casts for inline code since MSVC
1127 require them. Affected files lib/silcutil/silcbuffer.h,
1128 lib/trq/silcdlist.h and lib/trq/silclist.h.
1130 * Print warning in log files from now on if the packet
1131 decryption fails. Affected file silcd/server.c.
1133 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1135 * Changed the `say' client operation's interface to accept
1136 new `type' argument to indicate the type of the message sent
1137 by the library. The application may filter the library's
1138 messages according the type. The affected file is the
1139 lib/silcclient/silcapi.h.
1141 * Added two new functions to lib/silcclient/silcapi.h:
1142 silc_client_del_client and silc_client_del_client_by_id.
1143 Affected file lib/silcclient/idlist.c.
1145 * Moved the clientincludes.h from includes/ to silc/ and
1146 serverincludes.h from includes/ to silcd/.
1148 * The modes for the CMODE and CUMODE are now passed as
1149 uint32 for application with COMMAND_REPLY. The affected
1150 file is lib/silcclient/command_reply.c.
1152 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1154 * /WHOIS without arguments shows client's own information.
1155 Affected file lib/silcclient/command.c.
1157 * Changed PING to not accept any arguments. The specs
1158 says that client can ping only the connected server so
1159 requiring an argument is not needed. Affected file is
1160 lib/silcclient/command.c.
1162 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1164 * Fixed a fatal bug in private message sending and reception
1165 encryption and decryption when using private message keys.
1166 The implementation was incorrect and did not follow the
1167 specification. It causd that some of the message were
1168 lost since it did not use the sending and receiving keys
1169 as the protocol suggests. This has been fixed and will cause
1170 incompatibilities with older clients when sending private
1171 message encrypted with private message keys. Affected files
1172 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1173 and various other in Irssi SILC Client.
1175 Added `responder' boolean argument to the functions
1176 silc_client_add_private_message_key[_ske] to indicate when
1177 the key is added as responder or initiator of the key
1180 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Removed the silc_ske_check_version function and created
1183 a SilcSKECheckVersion callback. Added also a function
1184 silc_ske_set_callbacks that is now used to set all SKE
1185 callbacks. The callback functions are not given to
1186 the SKE functions anymore, but this function is used to
1189 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1191 * Added `silc_version' argument to the silc_client_alloc
1192 to define the version of the application for the library.
1193 The library will use the version string to compare it
1194 against the remote host's (usually a server) version
1195 string. Affected file lib/silcclient/silcapi.h
1197 * Added the KE protocol context to Key Agreement context
1198 in client library so that we can abort the SKE if it
1199 is in process when we get timeout. Affected file is
1200 lib/silcclient/client_keyagr.c.
1202 * Do not resolve the client ID forever if it returns in the
1203 first time that such client does not exist. This was done
1204 for example with private message. Affected file is
1205 lib/silcclient/client_prvmsg.c.
1207 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Do not add regex.h for WIN32. The affected file
1210 includes/silcincludes.h.
1212 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1213 not work yet 100%. It generates the DLL's automatically
1214 when compiling with --with-win32 under cygwin.
1216 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * lib/contrib/regex.c is not compiled on WIN32.
1220 * Added silc_net_get_socket_opt function to the
1221 lib/silcutil/silcnet.h.
1223 * Added includes/silcwin32.h for WIN32 specific includes
1226 * Do not use ptime structure or any of the posix process
1227 functions on WIN32 in lib/silccrypt/silrng.c.
1229 * Added silc_gettimeofday to provide generic function
1230 for struct timeval on all platforms. Added the function
1231 to lib/silcutil/silcutil.h.
1233 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1236 library as they clearly belong there. As a plus side we
1237 can make the actual socket connection routines platform
1240 Added also new generic function silc_socket_read and
1241 silc_socket_write (that used to be silc_packet_[read/write].
1242 The implementation of these are platform specific.
1244 * Added WIN32 specific routines of silc_socket_[read/write]
1245 to lib/silcutil/win32/silcwin32sockconn.c.
1247 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Added preliminary support for native WIN32 compilation under
1250 cygwin (using the -mno-cygwin option for GCC) to the
1251 ./configure.in.pre. The --with-win32 now prepares the
1252 compilation for native WIN32.
1254 * Rewrote the SILC Scheduler interface in the file
1255 lib/silcutil/silcschedule.h. The scheduler is now context
1256 based and does not have anymore any global static scheduler.
1257 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1258 and created lib/silcutil/win32 directory for WIN32 based
1261 * Added Unix specific network routines to the
1262 lib/silcutil/unix/silcunixnet.c and the old
1263 lib/silcutil/silcnet.c includes now only generic routines.
1265 Added WIN32 specific network routines to the
1266 lib/silcutil/win32/silcwin32net.c.
1268 * Added Unix specific utility functions from the
1269 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1271 * Added WIN32 SILC Scheduler to the file
1272 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1275 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Do not handle JOIN notify in the server if the target client
1278 is not registered (idata->registered == FALSE). The affected
1279 file is silcd/packet_receive.c.
1281 * Update the nickrec->founder in event_cumode in the Irssi SILC
1282 client. Affected file irssi/src/silc/core/silc-channels.c.
1284 * Fixed the CUMODE_CHANGE notify handling in the server when
1285 server and router are announcing their clients on channels.
1286 Now the mode changes are saved and notified correctly. The
1287 affected file is /silcd/packet_receive.c.
1289 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1290 They really did not replace the cache entry in the ID Cache.
1291 Now they do that. Affected file silcd/idlist.c.
1293 * Fixed the KICK notify handling in the Irssi SILC client to
1294 update the channel records so that the kicked client does not
1295 appear to be on the channel. The affected file is
1296 irssi/src/silc/core/silc-channels.c.
1298 * Always update the conn->current_channel when executing command
1299 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1301 * Fixed the KILL notify handling in Irssi SILC client to remove
1302 the killed client on all channels.
1304 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1306 * Fixed the silc_parse_command_line to remove extra spaces
1307 from the start and end of the arguments. Affected file is
1308 lib/silcutil/silcutil.c.
1310 * Cancel and free any active protocol in the function
1311 silc_server_close_connection. Affected file silcd/server.c.
1313 * Cancel and free any active protocol in the function
1314 silc_client_close_connction. Affected file is
1315 lib/silcclient/client.c.
1317 * Do not execute the KILL command for clients that are in
1318 history (ie. they are not in the network). Affected file is
1321 * Fixed KILL notify handling, client does not crash anymore.
1322 Affected file irssi/src/silc/core/silc-channels.c.
1324 * Reduced the default packet buffer size from 2048 to 1024 in
1325 lib/silccore/silcpacket.c.
1327 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1328 counter to the SKE context that is incresed when the SKE library
1329 performs async operation outside the library. If the outside
1330 process frees the SKE context and FREED status will be set
1331 and the library will detect after the sync operation that the
1332 libary is freed. The affected files are
1333 lib/silcske/silcske[_status].[ch].
1335 * Resolve the client entry information in the function
1336 silc_client_channel_message to assure that NULL pointer is not
1337 passed as client entry to the application. */
1339 * Fixed the task timeout calculation to assure that there is
1340 never negative timeouts. The affected file is
1341 lib/silcutil/silcschedule.c.
1343 * Fixed the channel user mode notification sending in server.
1344 It was sent point-to-point to the router (or to server by router)
1345 but it needs to be destined to a channel. The routines now
1346 supports sending the channel user mode notifys to the channels
1347 when announcing clients and channels. Affected files are
1348 silcd/server.c and silcd/packet_receive.c.
1350 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1351 It did not actually replace the old channel entry in the cache.
1352 Affected file lib/silcclient/client_notify.c.
1354 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * Fixed a possible crash in silc_packet_send_prepare. It now
1357 assures always that there is enough space in the buffer and
1358 at the tail area of the buffer (for MAC).
1360 Fixed the inbound buffer reallocation in silc_packet_read.
1361 It was old code and did not handle the reallocation correctly.
1364 The affected file is lib/silccore/silcpacket.c.
1366 * Fixed buffer overflow in silc_parse_nickname in the file
1367 lib/silcutil/silcutil.c.
1369 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * make install generates new server keys only if there is not
1374 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1376 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1377 Added check that if the NOREPLY is set then we will not send
1378 the away message. This avoids infinite loop of away messages
1379 if both clients are away. The affected file is
1380 lib/silcclient/client_prvmsg.c.
1382 * Fixed client crash if /NICK was given without arguments.
1383 Affected file lib/silcclient/command.c.
1385 * Server does not send the invite list in INVITE command back
1386 to the client if the list was not altered. Added this notion
1387 to the protocol spec as well. Affected file silcd/command.c.
1389 Fixed possible crash in INVITE command by checking the
1390 value of silc_server_get_client_route command.
1392 * Fixed the INVITE notify type handling. The arguments are now
1393 taken in correct order and client does not crash. The affected
1394 file is irssi/src/silc/core/silc-channels.c.
1396 Removed the "Inviting xxx to channel" message from the
1397 client library away and let the application handle it.
1398 Affected file lib/silcclient/command.c. Added that message
1399 to Irssi SILC client's message formats.
1401 * Fixed CMODE command crash in client. It now checks the
1402 amount of arguments correctly and does not crash. The affected
1403 file is lib/silcclient/command.c.
1405 * Do not create new channel automatically in silc_channels_join
1406 but check whether the channel by that name already exists.
1407 Affected file irssi/silc/core/silc-channels.c.
1409 * Do not send the SERVER_SIGNOFF to router if the disconnected
1410 entity was the router. Affected file silcd/server.c.
1412 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1413 SILC client as it was missing from there.
1415 Added the handling of the KICK notify to the Irssi SILC client
1416 as it was missing. Added "you have been kicked" message to
1417 Irssi SILC client's message modules formats.
1419 Added the handing of the KILL notify to the Irssi SILC client
1420 as it was missing. Added the kill message module formats
1423 The affected file is irssi/src/silc/core/silc-channels.c.
1425 * The router did not save the channel mode the server announced.
1426 Affected file silcd/packet_receive.c.
1428 * Fixed a possible crash in INFO command in server. If the
1429 server did not provide the server info it crashed. Affected
1430 file silcd/command.c.
1432 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Fixed the GETKEY command in the server to check also the
1435 global list. Otherwise the GETKEY would not work correctly
1436 in normal SILC server. Affected file silcd/command.c.
1438 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Fixed GETKEY crash, it crashed if the command did not succseed.
1442 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1445 is now real and not just an macro interface to GMP.
1447 Removed the entire GMP from the source tree and imported new
1448 NSS MPI library instead. Reason for removing GMP is that it is
1449 extremely large and compiles extremely slow. The NSS MPI
1450 is only a few files and compiles in less than 10 seconds.
1451 The speed is also about the same as GMP. The MPI is imported
1452 to lib/silcmath/mpi.
1454 If the system has GMP installed we will still use the GMP.
1455 If it is not then the NSS MPI will be compiled.
1457 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * Merged a long nickname (127 characters long) crash bugfix from
1460 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1462 * Merged a freed memory reference bugfix from Irssi CVS tree.
1463 Affected file irssi/src/core/commands.c.
1465 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * Added the server's public key sving and verification to the
1468 server when performing the SKE. This was missing and the
1469 remote server's (or router's) public key was accepted without
1470 checking whether we have it previously or trust it at all.
1471 Affected file silcd/protocol.c.
1473 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Check in the silc_server_timeout_remote if protocol is active
1476 and make sure that the protocol's final callback is called so
1477 that all memory if freed. Affected file silcd/server.c.
1479 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * silc_server_whois_send_reply crashed the server if the nickname
1482 was 127 characters long. Affected file silcd/command.c.
1484 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1486 * Added sanity check to the silc_server_new_client. If the hostname
1487 is provided inside username then check that the provided hostname
1488 really is the same as the resolved one. If the hostname was not
1489 resolved then check it from the public key. Affected file is
1490 silcd/packet_receive.c.
1492 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1493 if the server disconnected us and the connection is not valid
1494 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1496 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1497 the library to the lib/silcutil/silcutil.[ch].
1499 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Close log file after open. Affected file
1502 lib/silcutil/silclog.c.
1504 * Check whether sock == NULL in silc_client_send_packet and return
1505 if it is. Affected file lib/silcclient/silcclient.c.
1507 * Check rec->entry == NULL in the Irssi SILC Client before
1508 sending the channel message. Affecte file is
1509 irssi/src/silc/core/silc-servers.c.
1511 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Merged a splitted window bugfix from Irssi CVS tree. The
1514 affected file is irssi/src/fe-text/textbuffer-view.c.
1516 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1517 It did not print nickname.
1519 * Improved the distributions system a bit.
1521 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1524 irssi/src/fe-text/gui-window.c.
1526 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1527 to in-active server. The affected file is
1528 irssi/src/silc/core/client_ops.c.
1530 * Resolve the client in USERS command reply if the entry does
1531 not have username resolved. The affected file is
1532 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1533 command to WHOIS command to really resolve stuff. The USERS
1534 is not used any more in any critical section so WHOIS can
1535 be used even though it might be slower than IDENTIFY.
1537 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1540 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Changed the protocol API a bit more consistent in the
1543 lib/silccore/silcprotocol.[ch].
1545 * Changed the following headers to ROBODoc format:
1547 lib/silccore/silcpayload.h
1548 lib/silccore/silcprotocol.h
1549 lib/silccore/silcsockconn.h
1551 All core library headers are now formatted.
1553 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Fixed a bug in Irssi SILC client; do not show that you are
1556 server/router operator if you really are not. Affected file is
1557 irssi/src/silc/core/client_ops.c.
1559 * Renamed silc_command_free_payload to silc_command_payload_free.
1560 Affected file lib/silccore/silccommand.h
1562 * Added silcmath.h to include the prototoypes of various routines
1563 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1566 * Changed the following headers to ROBODoc format:
1568 lib/silccore/silcchannel.h
1569 lib/silccore/silccommand.h
1570 lib/silccore/silcid.h
1571 lib/silccore/silcidcache.h
1572 lib/silccore/silcmode.h
1573 lib/silccore/silcnotify.h
1574 lib/silccore/silcpacket.h
1575 lib/silcmath/silcmath.h
1577 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Added checking to the server code not to start the server if
1580 ciphers and stuff are not configured properly. Affected files
1581 silcd/serverconfig.[h] and silcd/server.c.
1583 * Changed the layout of the header files of the public interfaces
1584 in the SILC libraries. The new layout supports ROBODoc
1585 documentation tool (and some others) so that it is easy to create
1586 a library reference manual. All the other headers and source
1587 code must still follow the CodingStyle document. Also source
1588 code must not include these ROBODoc stuffs, only the headers.
1589 Furthermore, all public interface headers must now be named
1590 by using `silc' prefix, example: silcapi.h, silccipher.h.
1591 Some files were renamed due to this. All the other headers
1592 must not be used as public interfaces. I will update the
1593 CodingStyle document later. Changed following headers, so far:
1595 lib/silcclient/silcapi.h
1596 lib/silccore/silcauth.h
1597 lib/silccore/silcprivate.h
1598 lib/silccrypt/silcdh.h
1600 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Removed silc_client_packet_send_flush from the client library
1605 as it is not needed. Affected file lib/silcclient/client.[ch].
1607 * Added printing of message of unresolved authentication method
1608 to the Irssi SILC client. Added it to the module formats.
1609 Removed the same message from the client library.
1611 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added new distribution feature, DISTLABEL. Every distribution
1614 can define own preprocessor label that can be used in the
1615 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1616 file distributions, acconfig.h.pre and prepare.
1618 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Added Makefile.defines_int to include the actual definitions
1621 for Makefile.defines.in. Tested the new distribution system,
1622 created distributions and tested installation.
1624 * Added AWAY message printing to the Irssi SILC client. Added
1625 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1627 * Added SCONNECT command to call the SILC's CONNECT command.
1628 Cannot use CONNECT directly since Irssi uses that internally.
1629 Affected file irssi/src/silc/core/silc-servers.c.
1631 Added ACTION local command. It is same as ME command but takes
1632 the channel as mandatory argument.
1634 Rewrote some of the Irssi's help files to suite for SILC
1637 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Added Makefile.defines[.in] that should for now on be included
1640 in all Makefile.am file in the source tree. That file includes
1641 all common compilation definitions for SILC source tree.
1643 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Minor changes to the ./prepare script to change the package
1646 name according the distribution name to the configure.in.
1648 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Created new distribution system. Added file `distributions'
1651 that defines all the distributions that can be created out of
1652 the SILC source tree. The ./prepare script now reads that
1653 file to determine how to prepare the distributions. The
1654 first argument to the ./prepare is the name of the distribution
1655 and second is the version of the distribution. If given
1656 without arguments it creates the default (toolkit) distribution
1657 with the default version (defined in ./prepare).
1659 All Makefile.am files that are subject to the distributions
1660 are now named as Makefile.am.pre. These are ./Makefile.am
1661 and lib/Makefile.am. Others may be changed later.
1663 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Added invite list, ban list, some key management and connection
1666 error message printing to module formats in the Irssi SILC client.
1668 * Added new silc_client_set_away_message to set the away message
1669 that is back to the person who sent private message. The
1670 affected file lib/silcclient/silcapi.h and the
1671 lib/silcclient/client_prvmsg.c.
1673 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Fixed the private message sending in the Irssi SILC client,
1676 added local command KEY to the Irssi SILC client.
1678 Added key management and key agreement message formats to the
1679 irssi/src/fe-common/silc/module-formats.[ch].
1681 Added USERS (alias WHO) printing, server/router operator
1682 indication and LIST command printing to the module formats.
1684 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1686 * Fixed channel joining notify handling, cumode notify handling
1687 from Irssi SILC client.
1689 * Added SILC specific module-formats to the Irssi SILC client so
1690 that SILC specific message hilighting, colors etc is possible.
1691 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1693 Added channel mode, channel user mode, actions, notices,
1694 whois and whowas printing to the the module-formats.c.
1696 * Fixed a bug in channel deletion in the server. The channel
1697 is not left to the cache even if the channel founder auth mode
1698 is set when there are no users anymore on the channel. Affected
1699 file silcd/server.c.
1701 * The silc_net_localhost now resolves the entire hostname including
1702 the domain name. Affected file lib/silcutil/silcnet.c.
1704 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Changed the ask_passphrase client operation to be ascynchronous.
1707 It has now a completion callback and a context that the
1708 application must call after it has got the passphrase from
1709 the user. Affected files lib/silcclient/silcapi.h,
1710 lib/silcclient/protocol.c, lib/silcclient/command.c and
1713 Added SilcAskPassphrase callback that the application calls
1714 to deliver the passphrase to the library.
1716 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1717 The public key verification and especially a certificate
1718 verification is asynchronous procedure.
1720 Added new SILC_SKE_STATUS_PENDING status to indicate the
1721 request is pending and a callback will be called to finalize
1724 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1725 indicate that remote end did not send its public key (or
1726 certificate), even though we require it. Added check for this
1727 condition in the SKE. This was a security bug, now fixed.
1729 Defined new SilcSKEVerifyCbCompletion callback that is called
1730 when the verification process is completed.
1732 The affected files lib/silcske/silcske_status.h and
1733 lib/silcske/silcske.[ch].
1735 * Changed the verify_public_key client operation to be async
1736 as well. Defined SilcVerifyPublicKey callback that is used to
1737 indicate the success of the public key verification process.
1739 Changed the server and client to use the new async client
1742 * Changed the Irssi SILC client's internal scheduler to be called
1743 twice as many times as it used to be. As a result the client
1744 should be a bit faster now. Affected file is
1745 irssi/src/silc/core/silc-core.c.
1747 * Added support to Irssi SILC client of asynchronous public key
1748 verification and passphrase inquiry. Affected file is
1749 irssi/src/silc/core/silc-core.c.
1751 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Do not say "You have left channel %s" in client library.
1754 Moved it to the application. Affected files are
1755 lib/silcclient/command.c and silc/client_ops.c.
1757 * Fixed silc_client_get_clients. Command context was not
1758 duplicated and was freed memory in the callback. Affected
1759 file lib/silcclient/idlist.c.
1761 * Do not say "you are now talking..." on JOIN command in the
1762 client library. The appliation must handle it.
1764 * Do not say ".. changed topic to" in command reply in the
1765 client libary. The application must handle it.
1767 * Fixed TOPIC command sending in the client library.
1769 * Fixed a memory leak in silc_client_command_free in the file
1770 lib/silcclient/command.c.
1772 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Imported a modified version of Irssi client to the source tree.
1775 The Irssi will be used to create a new client called
1776 Irssi SILC. Imported to irssi/.
1778 Added silc_core_init_finish function to the Irssi. Affected
1779 file irssi/configure.in.
1781 A lot changes in the Makefile.ams around the irssi tree.
1783 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Do not rehash if the new size is same as the old size of the
1786 hash table, in the silc_hash_table_rehash*. The affected file
1787 lib/silcutil/silchashtable.c.
1789 * Replaced hash_table_del_by_context calls from the server
1790 (when channel->user_list and client->channels) to the
1791 hash_table_del as it is sufficient and faster.
1793 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1795 * Added silc_hash_table_list, silc_hash_table_get and the
1796 SilcHashTableList structure to provide an alternative way to
1797 traverse the hash table. The affected files are
1798 lib/silcutil/silchashtable.[ch].
1800 * Changed the server's idlist routines to use the hash table
1801 routines to optimize the code.
1803 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Replaced the client entry's `channel' list and channel entry's
1806 `user_list' list to hash tables for optimized lookup. Changed
1807 the code to use the hash table interface around the code.
1808 Affected file lib/silcd/idlist.[ch].
1810 * Added `auto_rehash' boolean argument to the function
1811 silc_hash_table_alloc to indicate whether the hash table should
1812 auto-rehash when it thinks is appropriate time. It will
1813 increase the hash table size if the there is twice as much
1814 entries in the table than the size of the table, and will
1815 decrease the size if there are twice as less entries than
1816 the size of the table.
1818 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1820 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1822 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * silc_idcache_purge_by_context deletes the entry now by context
1825 as it is supposed to do. Affected file lib/silccore/idcache.c.
1827 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1828 client is not anymore valid (WHOWAS givens the info) and not
1829 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1831 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Removed the `data' and `data_len' arguments from the ID Cache
1834 interfaces and added `name' argument. ID Cache does not handle
1835 anymore the binary data only a names associated with given ID.
1837 * When hashing a Client ID with silc_hash_id the entire ID is
1838 not hashed anymore, instead only the hash of the Client ID is
1839 hashed. This way we can access the Client ID from the cache
1840 with Client ID but with the hash of the ID (which is a hash of
1841 the nickname) as well without any difference in performance.
1843 Added also silc_idcache_find_by_id_one_ext to do one on one
1844 searching when we have the actual ID. Added also function
1845 silc_hash_client_id_compare. The affected files are
1846 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1848 * When hashing the name associated with a ID it is always done
1849 in lowercase. This way we can access the cache without worrying
1850 about case-sensitivity, even though, for example nicknames are
1853 * Fixed a bug in server with channel message sending. It put
1854 wrong ID type as destination ID. The affected file
1855 silcd/packet_send.c.
1857 * silc_idcache_del_by_context now deletes from all hash tables
1858 by context. Affected file lib/silccore/idcache.c.
1860 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Changed the client library to use the new ID Cache interface.
1863 Changes around the source tree.
1865 * Added silc_hash_table_rehash_ext to rehash with specific
1866 hash function. Affected file lib/silcutil/silchashtable.[ch].
1868 * Added silc_hash_string_compare to compare two strings in the
1869 hash table. Affected file lib/silcutil/silcutil.[ch].
1871 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Added new function silc_idcache_del_by_context into the
1874 lib/silccore/idcache.[ch].
1876 * Changed the server's ID list routines to use the new ID Cache
1877 interface. Changes around the source tree.
1879 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1881 * Added silc_hash_table_del[_by_context]_ext functions in to the
1882 lib/silcutil/silchashtable.[ch].
1884 Removed silc_hash_table_find_all* routines and added new
1885 silc_hash_table_find_foreach to replace them.
1887 Added silc_hash_table_replace_ext function as extended
1888 replacing function. Separated the simple hash table interface
1889 from the extended hash table interface in the file
1890 lib/silcutil/silchashtable.h.
1892 * Fixed minor bugs and changed it to use some of the new
1893 hash table functions in lib/silccore/idcache.c
1895 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added new function silc_hash_table_find_all to return all keys
1898 in the hash table by the specified key. As the hash table is
1899 collision resistant it also makes it possible to have several
1900 duplicate keys in the hash table. This function may be used to
1901 find all of the keys from the hash.
1903 Added user_context arguments to the SilcHashFunction,
1904 SilcHashCompare and SilcHashDestructor to deliver user specified
1907 Added new fuctions silc_hash_table_find[_all]_ext to do
1908 extended lookup with specified hash and compare functions and
1909 specified user contexts.
1911 Added new function silc_hash_table_add_ext to add the key
1912 with specified hash function and user context.
1914 Added new function silc_hash_table_foreach to traverse all
1915 entrys in the hash table. Added SilcHashForeach callback
1918 Added new function silc_hash_table_del_by_context to delete
1919 the entry only if the context associated with the key matches.
1921 Affected files are lib/silcutil/silchashtable.[ch].
1923 * Removed silc_hash_[server/client/channel]_id and added just
1924 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1925 silc_hash_id_compare to compare two ID's using as the hash table
1926 comparison function. Added also silc_hash_data to hash
1927 binary data and silc_hash_data_compare to compare it.
1929 * Removed silc_idlist_find_client_by_hash as it is not needed
1930 anymore. Affected file silcd/idlist.[ch].
1932 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1933 to use internally the SilcHashTable. The new ID Cache is a lot
1934 faster than the old one. Some of the ID Cache interface was also
1935 rewritten and obsolete and stupid functions were removed.
1937 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Added entry_count field to the SilcHashTable to keep the number
1940 of the entries in the table. Implemented the function
1941 silc_hash_table_rehash. Added new function
1942 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1944 Fixed a minor bug in silc_hash_table_free.
1946 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1947 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1948 into the lib/silcutil/silcutil.[ch].
1950 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Implemented a collision resistant hash table into the
1953 lib/silcutil/silchashtable[ch]. See the header and the source
1954 for the SilcHashTable API.
1956 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Merged dotconf version 1.0.2 into lib/dotconf.
1960 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Do not compile anything in lib/silcsim/* if the SIM support
1963 is not enabled. The tree should now compile without problems
1966 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Compiled the SILC under cygwin. Compiled and tested briefly
1969 without problems. More tests needed. The SIMs didn't compile
1972 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1974 * Fixed possible crash in silc_get_username in the
1975 lib/silcutil/silcutil.c.
1977 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * Fixed a va_arg in silc/client_ops.c.
1981 * Oops, RC5 routines were named AES and caused some problems
1982 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1984 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Added new SilcIDIP structure into the lib/silccore/id.h and
1987 replaced the old `ip' fields from all SILC ID's to that type.
1988 This is a step towards IPv6 support.
1990 The silc_id_get_len takes now the ID as an extra argument.
1991 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1992 both IPv4 and IPv6 based ID's.
1994 The affected files are lib/silccore/id.[ch] and other files
1995 around the tree using these routines.
1997 * Removed the ID length arguments in server from various
1998 silc_server_send_notify_* routines -> they are not needed
2001 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Fixed memory leak in silc_encode_pem_file in the file
2004 lib/silcutil/silcutil.c.
2006 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Check minor version as well in the SKE. Affected files are
2009 silcd/protocol.c and lib/silcclient/protocol.c.
2011 * Added --identifier option to the server so that an identifier
2012 can be when creating the public key for the server. Affected
2013 file is silcd/silcd.c.
2015 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2016 lib/silccrypt/silcpkcs.c.
2018 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Register default ciphers and stuff when using -C option with
2021 the server. Affected file sildc/silcd.c.
2023 * Put back the servers public key filename format, it is better
2024 than the new one. For now, the client keys are saved with the
2025 new filename format. The affected file silc/client_ops.c.
2027 * Implemented the Cipher API for the rest of the ciphers that
2028 did not implement it or implemented it the wrong way.
2030 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Register default ciphers and stuff when using the -S option
2033 in the client. Affected file silc/silc.c. Same also when
2034 creating new key pair with -C option.
2036 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Fixed the silc_verify_public_key client operation function to
2039 save the public keys differently. The fingerprint is now
2040 used as filename and not the hostname. This way also the
2041 client keys are saved uniquely and not with hostnames. The
2042 affected file is silc/client_ops.c.
2044 * Trimmed the silc_hash_fingerprint function to remove extra
2045 whitespaces from the end of the fingerprint. The affected
2046 file is lib/silccrypt/silchash.c.
2050 * Added silc_cipher_register_default function to register all
2051 default ciphers. It can be used when configuration files
2052 does not exist and the application does not want any specific
2053 ciphers in any specific order.
2055 The SilcDList is now used as silc_cipher_list dynamically
2056 allocated cipher list. Removed the static list all together
2057 and now all ciphers must be allocated to the dynamic list.
2058 The silc_cipher_alloc routine was changed to check only the
2061 All silc_cipher_* routines that used to return int returns
2064 The affected files lib/silccrypt/silccrypt.[ch].
2066 * The same thing was done to silc_hash_* as for silc_cipher_*
2067 routines. Affected files lib/silccrypt/silchash.[ch].
2069 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2070 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2071 Added also silc_pkcs_[un]register[_default] functions.
2072 Removed the data_context from the PKCS API.
2074 * Added silc_hmac_register_default function to register default
2075 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2076 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2077 to unregister all hmacs at once.
2079 * Register the default ciphers, hash functions, PKCSs and HMACs
2080 if client's configuration file does not exist. The affected
2083 * The client did not load the hash functions from the SIM
2084 modules at all. Added support for this. Affected file is
2085 silc/clientconfig.c.
2087 * When decoding public key with silc_pkcs_public_key_decode, check
2088 the supported algorithm only if PKCS are registered. Affected
2089 file lib/silccrypt/silcpkcs.c. The same was done with the
2090 silc_pkcs_private_key_decode.
2092 * Fixed the SILC List routines to keep the list always in order.
2093 It used to change the list's order when traversing the list but
2094 not it preserves the order. Affected file lib/trq/silclist.h.
2096 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Added the client library to use the SilcSocketConnection's
2099 reference counter (by silc_socket_dup) to prevent the bug that
2100 the socket object may be freed underneath async operation.
2102 * The name resolv library checking fixes in the configure.in.pre.
2105 * Created new version of the protocol drafts for future
2106 development. The -03 drafts are the ones that will be changed
2107 in the trunk now and the -02 will remain as they are.
2109 * Send list of CUMODE notifys to the router when announcing
2110 the channel users to the router. Affected file silcd/server.c.
2111 If the router receiving channel founder CUMODE for a channel
2112 that already has channel founder it will send CUMODE notify
2113 to the sender to remove the channel founder rights from the
2114 announced client. Affected file silcd/packet_receive.c.
2116 * The CUMODE notify may now use Server ID as well as the entity
2117 who changes the mode. Updated protocool specs.
2119 * Updated INSTALL and README files.
2121 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * New web pages in the http://silc.pspt.fi. The pages was
2128 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Implemented the [DenyConnectin] config section in the server.
2131 Added silc_server_config_denied_conn to check whether incoming
2132 connection is denied. Affected file silcd/serverconfig.[ch].
2134 * Do not check the ports when checking the incoming configuration
2135 data if the port is 0, meaning any. Affected file is
2136 silcd/serverconfig.c.
2138 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Fixed buffer overflow in silc_string_compare in the file
2141 lib/silcutil/silcutil.c.
2143 * Fixed double free in silc_server_command_leave in the file
2146 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Fixed the version checking in the server. Affected file is
2151 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Fixed the configuration data fetching when accepting new
2154 connections in the server. Affected file silcd/server.c.
2156 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Added `sender_entry' argument to the function
2159 silc_server_packet_relay_to_channel so that we can check
2160 whether some destination actually belongs to the same route
2161 the sender belongs (ie, we must not resend the packet to the
2162 sender). Affected file silcd/packet_send.[ch].
2164 * Added `servername' field to the SilcClientEntry in the server
2165 to hold the name of the server where client is from. Affected
2166 file is silcd/idlist.h.
2168 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Moved the channel message encrypting in the router betwen
2171 router connections from silc_server_channel_message to the
2172 silc_server_packet_relay_to_channel since we want to check
2173 whether we have anybody channel before encrypting anything.
2174 Affected files silcd/packet_[receive/send].c.
2176 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Fixed the [AdminConnection] server config section to support
2179 multiple entries. Affected file silcd/serverconfig.c.
2181 * Added support into the server to check the validity of the
2182 incoming connection before executing any KE or authentication
2185 * The connection configuration is now saved to the KE and
2186 connection auth protocol contexts and not fetched anymore in
2187 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2189 * The local hosts listenning address and port is also resolved
2190 now when starting the server. We want to have the socket object
2191 to include the real address and port for the listener. Added
2192 new function silc_net_check_local_by_sock into the files
2193 lib/silcutil/silcnet.[ch].
2195 * Fixed a broadcast bug in server -> do not broadcast if we
2198 * Fixed a routing bug. Do not route broadcast packets ever.
2199 Broadcast packets must be processed always and not routed since
2200 they may be destined to some other host than yourself and thus
2201 would get routed without no good reason. Affected file is
2204 * Added function silc_server_config_is_primary_route to check
2205 whether primary router connection has been configured (a router
2206 configuration that we are initiating). If there is not, we
2207 will assume that there is only two routers in the SILC network
2208 and we will use the incoming router connection as our primary
2209 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2211 * Changed the order of the broadcasting. Broadcast _after_ the
2212 packet has been processed not before. Affected file is
2215 * Fixed a [ClientConnection] parsing bug. The port was never
2216 parsed correctly thus resulting to port 0. Affected file
2217 silcd/serverconfig.c.
2219 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2220 argument and did not set the broadcast packet flag. Affected
2221 file silcd/packet_send.c. Fixed same bug in the function
2222 silc_server_send_notify as well.
2224 * If we receive NEW_ID packet for our own ID in the server, ignore
2227 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Removed the nickname from the Private Message Payload.
2232 Updated the code and the protocol specs.
2234 * Updated protocol specs for submitting to the IETF.
2236 * Tweaked the Random Number Generator a bit. Affected file
2237 lib/silccrypt/silcrng.c. Exported a new function
2238 silc_rng_[global]_add_noise which can be used to add more
2241 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Do not parse packets with different timeout when protocol
2244 is active -> may cause problem with rekey. Affected file
2247 * When server receives signoff notify it must not create
2248 new channel key if the client is on any channels since the
2249 sender of the signoff notify will create it.
2251 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Added printing of error messages during SKE protocol from the
2254 failure packet sent by server during SKE. Affected file
2257 * Removed the client's failure_callback handling with timeout
2258 and handle it immediately when received.
2260 * The SKE library returned wrong type in SUCCESS and FAILURE
2261 packets. They must be 32 bit MSB not 16 bit MSB.
2263 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * Ok, rewrote the logic of the re-key and now it seems to work.
2266 I tested it on high traffic with frequent re-keys without
2267 problems. Added hmac_receive (and renamed hmac to hmac_send)
2268 in SilcClientConnection in lib/silcclient/client.h and
2269 in SilcIDListData in silcd/idlist.h. Also, removed the
2270 SilcPacketParserContext's cipher and hmac fields as they are
2271 not needed anymore and actually caused some problems when
2272 the ciphers and hmac's changed underneath the packet parser.
2274 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * If re-key protocol is active then process the incoming packets
2277 synchronously since we must assure that icoming packets encrypted
2278 with the old key is processed before the new keys is set to
2279 use. This is true other packets than for REKEY packets.
2280 Affected file silcd/server.c. The same was done to client library
2281 as well, affected file lib/silcclient/client.c.
2283 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Fixed bug in client and server to accept the force send if
2286 the packet is send from silc_[server/client]_packet_process
2287 function. Otherwise the packets are never delivered, oops.
2289 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Disable force sending of packets when REKEY protocol is active.
2292 We must assure that no packet is sent directly when rekey is
2293 performed. All packets must be sent through packet queue.
2294 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2295 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2296 function is silc_[server/client]_packet_send_real to check
2299 * Replaced the SIM paths from example config files to
2300 /usr/local/modules. Also, make install creates now
2301 /usr/local/silc/logs directory to hold all the SILC server
2304 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Made the configure.in.pre work on Solaris. Patch by salo.
2308 * Made all ciphers compatible with non-x86 machines. Defined
2309 CBC mode macros into lib/silccrypt/ciphers_def.h.
2311 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Fixed the make install.
2315 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * When MAC computation fails the silc_packet_decrypt returned 0
2318 even though it was supposed to return -1. Fixed this. The
2319 affected file is lib/silccore/silcpacket.c.
2321 * Do not replace the config files in /etc/silc (in make install)
2322 if they already exist. Affected file ./Makefile.am.
2324 * Do not send re-key packets immediately but through packet queue.
2325 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2327 * Changed silc_net_check_host_by_sock to return FALSE if the
2328 IP/DNS could not be resolved. Though, it returns the IP address
2329 now even if it could not resolve it (but returns also FALSE).
2330 Affected file lib/silcutil/silcnet.[ch].
2332 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Added silc_pkcs_decode_identifier to decode the public key's
2335 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2336 Added also silc_pkcs_free_identifier. Added also new context
2337 SilcPublicKeyIdentifier.
2339 * Added -S option to the silc client. It is used to dump the
2340 contents of the specified public key file.
2342 * Changed the PKCS api to return the public key length when
2343 setting the public key.
2345 * Fixed a fatal bug in the public and private key file loading.
2346 Affected file lib/silccrypt/silcpkcs.c.
2348 * Execute the packet parsing for client with zero (0) timeout
2349 if the protocol is active. Affected file silcd/server.c.
2351 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Made the key generation options to the silcd program. Added
2354 -C option, equivalent to client's option.
2356 * Added new [ServerKeys] config section to the server. It
2357 configures the server's public and private key.
2359 * Defined generic Public Key Payload into the protocol
2360 specification to send specific type of public keys and
2363 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2364 public key or certificate.
2366 * Implemented the GETKEY command to the server and to the
2367 client library and on user interface.
2369 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Made preliminary `make install' work.
2373 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Added SilcServerRekey context into silcd/idlist.h.
2377 * Added the PFS support as defined in the specification to the
2378 SKE protocol. Affected files lib/silcske/*.c.
2380 * Added `ske_group' field to the SilcServerRekey context to hold
2381 the number of the SKE group that is used with PFS in re-key.
2382 Affected file silcd/idlist.h.
2384 * Added PFS re-key support to the server. Affected file is
2387 * Added silc_protocol_cancel to cancel execution of the next
2388 state of the protocol. Affected file is
2389 lib/silccore/silcprotocol.[ch].
2391 * Added the re-key support with and without PFS to the client
2392 library. Re-key is performed once in an hour, by default.
2394 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2395 Added silc_client_rekey_callback and silc_client_rekey_final.
2396 Affected files are lib/silcclient/protocol.[ch] and
2397 lib/silcclient/client.[ch].
2399 * Removed the `hmac_key' and `hmac_key_len' fields from the
2400 SilcClientConnection structure; not needed. Affected file is
2401 lib/silcclient/client.h.
2405 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Do not ask whether user wants to use the negotiated private key
2408 for private messages, just use it. Affected file is
2409 silc/local_command.c.
2411 * Added `send_enc_key' and `enc_key_len' fields to the
2412 SilcIDListData structure since they are needed in the re-key
2413 phase. Affected file is silcd/idlist.[ch].
2415 * Implemented the simple re-key protocol into the server.
2416 Affected files silcd/server.c and silcd/protocol.[ch]. The
2417 re-key will be performed once in an hour, by default.
2419 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2420 Added silc_server_rekey, silc_server_rekey_callback and
2421 silc_server_rekey_final.
2423 * Removed Tunneled flag from the protocol. Updated the code
2424 and the specifications.
2426 * Adde `pfs' field to the SilcIDListData to indicate whether
2427 the PFS is to be performed in the re-key. Affected file is
2430 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2433 int64 of at least the xintXX size. If void * is less that 4
2434 bytes uint32 * will be used. Defined bool as boolean.
2436 * Changed _ALL_ unsigned long and unsigned int to uint32,
2437 unsgined short to uint16 in the source tree.
2439 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2440 not handle clients that has entry->data.registered == FALSE.
2441 They are not in the network anymore. Affected file is
2444 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Implemented the sending of the SERVER_SIGNOFF notify in the
2447 server. Affected file is silcd/server.c.
2449 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2450 Added also silc_notify_payload_encode_args into the
2451 lib/silccore/silcnotify.[ch].
2453 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2454 Affected file silcd/packet_receive.c.
2456 * Implemented the SERVER_SIGNOFF notify handling in the client
2457 library. Affected file lib/silcclient/client_notify.c. Also,
2458 implemnted the printing of the SERVER_SIGNOFF info to the
2459 application. Affected file silc/client_ops.c.
2461 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2462 if the deleting was successful. Affected file silcd/idlist.[ch].
2464 * Added support for public key authentication in the connection
2465 authentication protocol in the client library. Affected file
2466 lib/silcclient/protocol.c.
2468 * Changed the server's silc_idlist_get_clients_by_* interface
2469 to support already allocated array so that new entries may be
2470 added to pre-allocated array. Affected file silcd/idlist.[ch].
2471 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2472 and command replies.
2474 * All command reply functions in the server now calls the
2475 pending command callback even if error occured. This way the
2476 error will be delivered to the client as well. Affected files
2477 silcd/command.c and silcd/command_reply.c.
2479 * Fixed INFO command to return local server's info if no server
2480 was provided. Affected file lib/silcclient/command.c.
2482 * Removed RESTART command for good. Updated the code and the
2485 * Rewrote parts of the task system. It is a bit simpler now.
2486 Removed unsued task priorities. The affected files are
2487 lib/silcutil/silctask.[ch].
2489 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Moved the USERS printing from the library to the application.
2492 Affected files lib/silcclient/command.c and silc/client_ops.c.
2494 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Added channel key re-key support. The re-key is perfomed
2499 only by the router and is done once in an hour. Added `rekey'
2500 field to the SilcChannelEntry in the server. Affected files
2501 silcd/server.c and silcd/idlist.h.
2503 * Added silc_task_unregister_by_context into the file
2504 lib/silcutil/silctask.[ch].
2506 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Added SILC_UMODE_GONE mode to indicate when the client is not
2509 present in the SILC network. Added also support to the local
2510 command AWAY that will set this mode. Added support of showing
2511 "xxx is gone" in WHOIS command. The USERS command shows the
2512 gone status as well.
2514 * Fixed setting server and router operator privileges in the
2515 server's UMODE command. Affected file silcd/command.c.
2517 * Merged the SKE KE1 and KE2 payloads into one payload. The
2518 new KE payload is equivalent to the old KE2 payload.
2520 Cleaned up the SKE Start Payload parsing. It now uses the
2521 simple buffer unformatting to do the parsing. A lot faster
2524 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2525 to the SKE that is used to indicate whether both of the SKE
2526 parties should perform authentication. By default only the
2527 responder performs authentication. By setting this flag also
2528 the initiator must do authentication. By default it is unset
2529 since in normal SKE case, client to server connection, only
2530 the responder should do authentication. When doing SKE between
2531 two clients both should perform authentication. Updated the
2532 code and the protocol specs.
2534 * A little fix to IDENTIFY command in the server. Search the
2535 client first by hash not nickname. Affected file is
2538 * Fixed the silc_client_close_connection to support closing
2539 the client to client connections wihtout deleting too much
2540 data. Affected file lib/silcclient/client.c.
2542 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2543 are received if protocol used to be active but is not anymore
2544 the application would crash due to NULL pointer dereference.
2545 Affected files silcd/server.c and lib/silcclient/client.c.
2547 * Added `hash' field to the SilcClientConnection to include
2548 the hash function negotiated in the SKE protocol.
2550 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2551 to set the channel founder authentication data. A client can
2552 claim the founder rights later by providing the authentication
2553 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2554 This way the channel founder can regain the channel founder
2555 privileges even it is left the channel. This works only on
2556 local server and the client must be connected to the same
2557 server to be able to regain the founder rights. Updated the
2558 protocol specs accordingly.
2560 Added support to the CMODE command in the client to set the
2561 founder auth data. Read the README to see how to set it.
2563 Added support to the CUMODE command to claim the founder
2564 rights. Read the README to see how to do it.
2566 Added support for the founder authentication to the Channel
2567 Entry in the server. Affected file silcd/idlist.h.
2569 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2570 server's CMODE command. Affected file silcd/command.c.
2572 * Added the following new functions into lib/silccore/silcauth.[ch]:
2573 silc_auth_get_method and silc_auth_get_data.
2575 * The server now saves the remote hosts public key to the
2576 SilcIDListData pointer. Affected file silcd/protocol.c.
2578 * The normal server now does not remove the channel entry from
2579 the cache if the founder authentication data is set. It used
2580 to remove it if the founder was the last one on the channel on
2581 the server and left the channel. The auth data is saved and
2582 if the channel is re-joined later the old entry is used with
2583 the old auth data. Affected files silcd/command_reply.c and
2586 * Removed the `pkcs' field from the SilcIDListData structure
2587 in the server; it is not used. Affected file silcd/idlist.h.
2589 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Fixed packet processing on slow links. Partial packets were
2592 never re-processed because the incoming data buffer was cleared
2593 by the application. Application must not directly clear the
2594 sock->inbuf, the packet processing routines handle it. Fixed
2595 this in client library and in server.
2597 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Fixed the WHOIS and IDENTIFY send reply function to really
2600 check whether to send list or just one entry. Affected file
2603 * Cleaned up the LEAVE command's channel key distribution. The
2604 affected file silcd/command.c.
2606 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2607 can enforce the channel mode as well. In that case the ID
2608 includes the ID of the server. The code now enforces the
2609 mode change if the router have different mode than the server.
2611 * The notify client operation with CMODE_CHANGE notify can now
2612 return NULL client_entry pointer if the CMODE was not changed
2613 by client. Application must check for this.
2615 * Added <Server ID> argument to INFO command to support server
2616 info fetching by Server ID.
2618 * Added silc_server_announce_get_channel_users to get assembled
2619 packets of channel users of the specified channel. Affected
2620 file silcd/server.[ch].
2622 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2623 was freed underneath the ID Cache.
2625 * Re-announce clients when the server received CHANNEL_CHANGE
2626 notify from the router. Affected file silcd/packet_send.c.
2628 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2631 crashed since it did not handle the fact that there is no cipher
2632 called "3" and didn't check the error condition. Now fixed.
2634 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2635 flag. It can be used to send message requests.
2637 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Implemented the RESTART command in the client.
2641 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2642 notice type messages. Added notice printing to the user
2645 * The channel keys are not re-generated if the channel's mode
2646 is PRIVKEY, ie private key on the channel exists. Affected
2647 files silcd/server.c and silcd/command.c.
2649 * Fixed a little bug in channel message delivery when channel
2650 private keys are set in the server. Affected file is
2651 silcd/packet_send.c.
2653 * Changed the setting on channel->on_channel = TRUE from the
2654 silc_client_save_channel_key to the JOIN command reply. The
2655 key payload is not received if the private channel key is set.
2656 Affected file lib/silcclient/command_reply.c and the
2657 lib/silcclient/client_channel.c.
2659 * When the CMODE_CHANGE notify is sent and the channel private
2660 key mode is removed the channel key must be re-generated in
2661 other cells as well. Added this support for the router in the
2662 silcd/packet_receive.c.
2664 * Added new local command NOTICE to send notice message on
2665 channel. Affected file silc/local_command.[ch].
2667 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Added new local command ME to the client. It is used to send
2670 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2671 some action. Affected file silc/local_command.[ch].
2673 * Changed channel_message and private_message client operations
2674 to deliver the message flags to the application. Added also
2675 the `flags' arguments to the silc_client_send_channel_message
2676 and silc_client_send_private_message functions. Affected file
2679 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Redefined the Private Message Payload to support private message
2682 keys and to support the new private message flags. Updated
2683 the protocol specs. Flags makes it possible to have for example
2684 CTCP style messages.
2686 * Added new type SilcPrivateMessagePayload and defined an API
2687 for it in the lib/silcclient/silcprivate.[ch].
2689 * Tested private message private keys successfully. Tested the
2690 private message key set, unset and list commands with the new
2693 * Redefined the Channel Message Payload to include the channel
2694 message flags (equal with private message flags) to support
2695 for example CTCP style messages.
2697 * Defined some of the message (for channel and private message)
2698 flags. Updated the protocol specs and added the flags to the
2699 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2701 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Added SilcKeyAgreementStatus type to the key agreement routines
2704 to indicate the current status and error if one occured.
2705 The status types are defined in the lib/silcclient/silcapi.h.
2707 * Added new local command KEY that is used to set and unset private
2708 keys for channels, set and unset private keys for private messages
2709 with remote clients and to send key agreement requests and
2710 negotiate the key agreement protocol with remote client. The
2711 key agreement is supported only to negotiate private message keys,
2712 it currently cannot be used to negotiate private keys for channels,
2713 as it is not convenient for that purpose.
2715 * Fixed a minor pending callback setting bug in the function
2716 silc_client_get_client_by_id_resolve, now the function works.
2717 Affected file lib/silcclient/idlist.c.
2719 * Added function silc_net_get_local_port to get local bound
2720 port by socket. Added to lib/silcutil/silcnet.[ch].
2722 * Added `sockets' and `sockets_count' fields to the SilcClient
2723 object. They hold the sockets of the listenning sockets in
2724 the client. Listenning sockets may be for example the key
2725 agreement server. Affected file lib/silcclient/client.[ch].
2726 Added functions the silc_client_add_socket and the
2727 silc_client_del_socket. They are exported to the application
2730 * Added ~./silc/clientkeys to support other client's public keys.
2732 * Renamed verify_server_key client operation to verify_public_key
2733 and added one argument to indicate the type of the connection
2734 (server, client etc.).
2736 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Added silc_server_connection_auth_request to handle the
2739 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2740 silcd/packet_receive.[ch].
2742 * Added silc_server_send_connection_auth_request into the
2743 silcd/packet_send.c to send the connection auth request packet.
2745 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2748 * Fixed the public key authentication in responder side in the
2749 server. The `auth_data' pointer includes the SilcPublicKey
2750 not the path to the public key. Affected file silcd/protocol.c.
2752 * Implemented the public key authentication in the initiator side
2753 in the server. Affected file silcd/protocol.c.
2755 * Removed the [RedirectClient] config section from the server
2756 configuration. Is not needed and I don't want to implement it.
2758 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Cleaned up the CMODE command in the server. It now works
2761 correctly and supports all the modes defined in the protocol.
2762 Affected file is silcd/command.c.
2764 * Added `hmac_name' field to the SilcChannelEntry in the server
2765 to hold the default HMAC of the channel. It can be set when
2766 creating the channel (with JOIN command). Affected files
2769 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2770 type to indicate the change of the current cipher and hmac
2771 on the channel. Client can safely ignore the <cipher> argument
2772 (if it chooses to do so) since the CHANNEL_KEY packet will
2773 force the channel key change anyway. The <hmac> argument is
2774 important since the client is responsible of setting the new
2775 HMAC and the hmac key into use.
2777 * Fixed the CMODE command in the client library as well.
2779 * Tested CMODE command in router environment successfully.
2781 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Show the version of the remote client (or server) when connecting
2784 to the server. It is logged to the log file. Affected file
2785 is silcd/protocol.c.
2787 * Fixed the KILLED notify handling in the client library. The
2788 client must be removed from all channels when receiving the
2791 Also, do not remove the client entry when giving the KILL
2792 command but when the KILLED notify is received.
2794 * Removed silc_idlist_find_client_by_nickname from the server.
2795 Not needed anymore. Affected files silcd/idlist.[ch].
2797 * Implemented the CHANNEL_CHANGE notify type handling to the
2798 server. Affected file silcd/server.c.
2802 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Added silc_server_send_notify_invite to send the INVITE
2805 notify between routers.
2807 * Implemented the INVITE command correctly to the server.
2809 * Implemented the INVITE notify type handling in the server.
2811 * Implemented the INVITE command to the client library and on the
2814 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Added function silc_server_get_client_resolve to find the
2817 client entry by ID from all ID lists and then resolve it
2818 (using WHOIS) if it cannot be found. Affected file is
2821 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Implemented the BAN command to the client library.
2825 * The JOIN command in the server now checks the invite list
2828 * Changed the silc_command_reply_payload_encode_va and the
2829 silc_command_payload_encode_va to support that if argument is
2830 NULL it ignores and checks the next argument. Affected file
2831 lib/silccore/silccommand.c.
2833 * Added silc_server_send_notify_ban to send the BAN notify
2834 type between routers.
2836 * Chaned the silc_notify_payload_encode to support that if
2837 argument is NULL it ignores and checks the next argument.
2838 Affected file lib/silccore/silcnotify.c.
2840 * Tested ban lists in router environment successfully.
2842 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Implemented BAN command to the server, in silcd/command.[ch].
2846 * Removed the BAN and INVITE_LIST modes from the CMODE command
2849 * Added function silc_string_match to regex match two strings.
2850 Affected files lib/silcutil/silcutil.[ch].
2852 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Redefined parts of the SilcChannelEntry in the server to support
2855 the new ban and invite lists.
2857 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Redefined the INVITE command. The same command can be used to
2860 invite individuals to the channel but also to manage the invite
2861 list of the channel (to add to and remove from the invite list).
2862 Updated the protocol specs.
2864 * Added new command SILC_COMMAND_BAN that can be used to manage
2865 the ban list of the channel. Updated the protocol specs.
2867 * Removed the channel modes: the SILC_CMODE_BAN and the
2868 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2869 in the CMODE command. The equivalent features are now available
2870 using INVITE and BAN commands. Updated the protocol specs.
2872 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2873 in the network about change in the current ban list. The notify
2874 type is not used by the client.
2876 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2877 support the invite lists.
2879 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Added new function silc_string_regexify that converts string
2882 including wildcard characters into regex string that can
2883 be used by the GNU regex library. Added into the file
2884 lib/silcutil/silcutil.[ch].
2886 Added silc_string_regex_combine to combine to regex strings
2887 into one so that they can be used as one regex string by
2888 the GNU regex library. Added into the file
2889 lib/silcutil/silcutil.[ch].
2891 Added silc_string_regex_match to match two strings. It returns
2892 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2894 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Imported GNU regex to the soruce tree into lib/contrib.
2897 Fixed some compiler warning from the regex.c.
2899 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Fixed MOTD command in the server to work in router environment.
2903 * Fixed the MOTD command in the client library to support
2904 the server argument in the command.
2906 * Added `nickname_len' argument to the silc_idlist_add_client
2907 in the server, as the `nickname' argument may be binary data
2910 * Added silc_idlist_get_channels to return all channels from
2913 * Implemented LIST command to the server. Affected file is
2916 * Implemented the LIST command to the client library and on the
2919 * Added [<user count>] argument to the LIST command reply.
2920 With private channels the user count is not shown.
2922 * Updated TODO and README.
2924 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * The client entry's data.registered must be TRUE even with
2927 global client entry on global client list. The data.registered
2928 is used to check whether the client is anymore in the network,
2929 for example with WHOWAS command so it must be valid.
2931 * Fixed the WHOWAS command in the server. It now actually works
2932 in router environment. Added function into silcd/command_reply.c
2933 silc_server_command_reply_whowas_save.
2935 * Added silc_idlist_purge function to the silcd/idlist.c
2936 to periodically purge the ID Cache.
2938 * Fixed INFO command in the server. It works now in router
2939 environment. Added <server name> argument to the INFO command
2940 reply. Updated the protocol specs.
2942 * Fixed minor bug in silc_idcache_purge to not purge if the
2943 expire value is zero.
2945 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2946 they were buggy because of the WHOWAS information.
2948 * Fixed local command MSG to handle the async resolving of
2949 the remote client properly. It used to fail the first MSG.
2950 Affected file silc/local_command.c.
2952 * Added `data_len' field to SilcIDCache context.
2954 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Update TODO. Todo in commands in the server.
2958 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2961 used by routers as broadcast packet to inform other routers
2962 about the changed user mode.
2964 Implemented the notify handling in the server. Affected file is
2965 silcd/packet_receive.c. Added the function
2966 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2968 * Added new generic Channel Payload and deprecated the New Channel
2969 Payload. The New Channel Payload is now the generic Channel
2972 * Added new argument `mode' to the silc_server_send_new_channel
2973 as it is required in the Channel Payload now.
2975 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2976 and created a new and real SilChannelPayload to represent the
2977 new generic Channel Payload. Implemented the encode/decode
2978 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2980 * Added silc_server_get_client_channel_list to return the list
2981 of channels the client has joined for WHOIS command reply.
2982 Affected file silcd/server.[ch].
2984 * Implemented the channel list sending in the WHOIS command reply
2985 in server and in the client.
2987 Implemented the channel list displaying on the user interface
2988 as well. Affected file silc/client_ops.c.
2990 * Added silc_channel_payload_parse_list to parse list of Channel
2991 Payloads. It returns SilcDList list of SilcChannelPayloads.
2992 Client for example can use this function to parse the list of
2993 channels it receives in the WHOIS command reply. The caller
2994 must free the list by calling silc_channel_payload_list_free.
2995 Affected files lib/silccore/silcchannel.[ch].
2997 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Added one new argument <user mode> to the WHOIS command reply
3000 to return the mode of the user in SILC. Updated the protocol
3003 Implemented it to the server and client.
3005 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed the mode printing on the user interface on joining.
3008 Affected file silc/client_ops.c.
3010 * Implemented the UMODE command and user modes in general to the
3011 client library and to the user interface.
3013 * Implemented the UMODE command to the server.
3015 * The server now sends UNKNOWN_COMMAND error status if client sends
3016 unknown command. Affected file silcd/command.c.
3018 * All server commands now handle the command identifier the right
3019 way when sending the command reply to the client. The client can
3020 use to identify the command replies with the identifier.
3022 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Added silc_server_get_client_route to resolve the route to
3025 the client indicated by the client ID. Affected file is
3028 * Added silc_server_relay_packet as general function to relay
3029 packet to arbitrary destination. This deprecates functions
3030 like _send_private_message_key, _relay_notify etc. Affected
3031 file is silcd/packet_send.[ch].
3033 Removed silc_server_send_key_agreement,
3034 silc_server_send_private_message_key and
3035 silc_server_packet_relay_notify functions from the file
3036 silcd/packet_send.[ch].
3040 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3041 server. Affected file silcd/packet_receive.[ch].
3043 * Implemented the KILL command to the client. Implemented the
3044 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3045 Affected files lib/silcclient/command[_reply].c and
3046 lib/silcclient/client_notify.c. Implemented the KILL notify
3047 printing in the user inteface.
3049 * Fixed a lot silc_parse_nick memory leaks from the client
3050 library in the file lib/silcclient/command.c.
3052 * Changed the silc_server_send_notify_on_channels's `sender'
3053 argument from SilcSocketConnection to SilcClientEntry to
3054 check the sender as entry and not as connection object and not
3055 to send to the client provided as argument. The affected file
3056 is silcd/packet_send.[ch].
3058 * The notify packets that are destined directly to the client used
3059 to not to be processed by the server. Now changed that and the
3060 server processes all notify packets. After relaying the packet
3061 to the client the notify packet is processed in the server.
3063 * The silc_server_free_client_data now checks whether there is
3064 pending outgoing traffic for the client and purges the data to
3065 the network before removing the client entry.
3067 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3070 an client is killed from the SILC Network. Updated the protocol
3073 Added new function silc_server_send_notify_killed to the
3074 silcd/packet_send.[ch].
3076 * Added function silc_server_packet_relay_notify to relay notify
3077 packets that are destined directly to a client. In this case
3078 the server does not process the notify packets but merely relays
3079 it to the client. Affected file silcd/packet_send.[ch].
3081 Added also silc_server_packet_process_relay_notify to check
3082 whereto relay the notify. Affected file is
3083 silcd/packet_receive.[ch].
3085 * Implemented the KILL command to the server.
3089 * Added the backup schema desgined last fall to the protocol
3090 specs for everyone to see. The specification is in the
3091 *-spec-xx.txt draft and the packet type definitions for the
3092 backup routers is in *-pp-xx.txt draft. Thusly, added also
3093 new packet type SILC_PACKET_CELL_ROUTERS.
3095 * A big security problem in the implementation discovered. The
3096 signoff of an client did not cause new channel key generation
3097 which it of course should've done. The channel keys must be
3098 always re-generated when client leaves (or signoffs) the channel.
3099 The silc_server_remove_from_channels funtion now handles
3100 the channel key re-generation.
3102 * Added `sender' argument to the silc_server_send_notify_on_channels
3103 to not to send the client provided as argument. Affected file
3104 silcd/packet_send.[ch].
3106 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Implemented OPER and SILCOPER commands into the server and
3111 * Added silc_auth_verify and silc_auth_verify_data to verify
3112 the authentication directly from the authentication payload.
3113 It supports verifying both passphrase and public key based
3114 authentication. Affected file lib/silccore/silcauth.[ch].
3116 * Added `hash' field to the SilcIDListData structure. It is the
3117 hash negotiated in the SKE protocol. Affected file is
3120 * Slight redesigning of the SilcAuthPayload handling routines.
3121 Do not send SilcPKCS but SilcPublicKey as argument.
3123 * Implemented the public key authentication support to the
3124 serverconfig. The public key is loaded from the provided path
3125 and saved as authentication data to void * pointer. Thus,
3126 changed the unsigned char *auth_data to void *auth_data;
3128 * Fixed SHUTDOWN command to send the reply before the server
3129 is shutdown. :) Affected file silcd/command.c.
3131 * Fixed fatal bug in CONNECT command. The hostname was invalid
3132 memory and server crashed. Affected file silcd/command.c.
3134 * Fixed fatal bug in CLOSE command. The server_entry became
3135 invalid but was referenced later in the command. Affected file
3138 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Fixed fatal bug in failure packet handling. Server ignored
3141 the failure and thus crashed when it came.
3145 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3148 that the command may be executed only once in (about) 2 seconds.
3149 The old SILC_CF_LAG flag is same but allows command bursts up
3150 to five before limiting.
3152 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3153 server code. Various commands now includes the CF_LAG_STRICT
3154 flag to disallow any kind of miss-use of the command.
3156 * Fixed the silc_buffer_unformat to not to allocate any data
3157 if the length of the data is zero. It used to allocate the
3158 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3160 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Changed the format of AdminConnection configuration section
3163 in the server. Added username of the admin to the format.
3164 Affected files silcd/serverconfig.[ch].
3166 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3167 to return admin configuration data by host, username and/or
3170 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Implemented WHOWAS command to the server. Added the functions:
3174 silc_server_command_whowas_parse,
3175 silc_server_command_whowas_send_reply,
3176 silc_server_command_whowas_from_client and
3177 silc_server_command_whowas_from_server
3179 * Added <Client ID> argument to the WHOWAS command reply. Updated
3180 the protocol specs accordingly.
3182 * Implemented WHOWAS command and command_reply to the client
3185 Implemented the WHOWAS printing on the user interface.
3187 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Added new argument to the WHOWAS command reply, the real name.
3190 It is an optional argument. Updated the protocol specs.
3192 * Added SilcIDCacheDestructor callback that is registered when
3193 the SilcIDCache is allocated. The callback is called when
3194 an cache entry in the ID Cache expires, or is purged from the
3195 cache. Added into lib/silccore/idcache.[ch].
3197 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3198 to destruct the client entries when the cache entry expires.
3199 Other ID Cache's in server and in the client library ignores
3202 * If the ID Cache entry's `expire' field is zero then the entry
3203 never expires. Added boolean `expire' argument to the
3204 silc_idcache_add function in the lib/silccore/idcache.[ch].
3205 If it is TRUE the default expiry value is used.
3207 * Added silc_server_free_client_data_timeout that is registered
3208 when client disconnects. By default for 5 minutes we preserve
3209 the client entry for history - for WHOWAS command.
3211 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Added support to the server to enforce that commands are not
3214 executed more than once in 2 seconds. If server receives
3215 commands from client more frequently, timeout is registered
3216 to process the commands. Affected file silcd/command.c.
3217 Added new function silc_server_command_process_timeout.
3219 * Changed NICK_NOTIFY handling in client library to check that
3220 if the client's nickname was changed, so there is no need to
3221 resolve anything from the server.
3223 * Removed error printing from the WHOIS and IDENTIFY commands.
3224 If error occurs then it is ignored silently in the client library.
3225 The application, however, may map the received error to
3226 human readable error string. The application currently maps
3227 the NO_SUCH_NICKNAME error to string.
3229 * Made the command status message public to the application. Moved
3230 them from lib/silcclient/command_reply.c to
3231 lib/silcclient/command_reply.h. The application can map the
3232 received command status to the string with the
3233 silc_client_command_status_message function.
3235 * Added check to the server to check that client's ID is same
3236 as the Source ID in the packet the client sent. They must
3239 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Added dist-bzip hook to the Makefile.am to make bzip2
3242 compressed distributions.
3244 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Server now enforces the maximum length for the nickname and
3247 the channel as protocol specification dictates. 128 bytes for
3248 nickname and 256 bytes for channel name.
3250 * Moved the WHOIS printing to the application. The client libary
3251 does not print out the WHOIS information anymore, the application
3252 must do it. Renamed silc_client_command_reply_whois_print to
3253 the silc_client_command_reply_whois_save.
3255 The client's idle time is also sent to the application now, and
3256 the idle is shown on screen.
3258 * Added silc_client_command_reply_identify_save to save the
3259 received IDENTIFY entries.
3261 * Do not check for channel private keys in message sending and
3262 reception if the channel does not have the PRIVKEY mode set.
3263 Affected file lib/silclient/client_channel.c.
3265 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3268 just surfaced after chaning the JOIN procedure.
3270 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Added silc_client_get_clients_by_list to get client entries
3273 from Client ID list, that is returned for example by JOIN
3274 and USERS command replies. The application should use this
3275 function for example when JOIN command reply is received to
3276 resolve the clients already on the channel (library does not
3277 do that anymore as USERS command reply is not used in the JOIN
3278 procedure anymore). Affected files lib/silcclient/silcapi.h and
3279 lib/silcclient/idlist.c.
3281 * JOIN command reply and USERS command reply returns now SilcBuffer
3282 pointers instead of unsigned char pointers when returning
3283 the client list and mode list.
3285 * Added <Client ID> argument to the JOIN command reply, mainly
3286 for the server to identify for which client the command was
3287 originally sent. Updated protocol specs accordingly.
3289 * Added SilcDlist private_key pointer to the SilcChannelEntry
3290 in the client to support the channel private keys. Affected
3291 file is lib/silcclient/idlist.h.
3293 * Added SilcChannelPrivateKey argument to the function
3294 silc_client_send_channel_message so that application can choose
3295 to use specific private ke if it wants to. If it is not provided,
3296 the normal channel key is used, unless private keys are set.
3297 In this case the first (key that was added first) is used
3298 as the encryption key.
3300 * Implemented the support for channel private key handling.
3301 Implemented the following functions:
3303 silc_client_add_channel_private_key,
3304 silc_client_del_channel_private_keys,
3305 silc_client_del_channel_private_key,
3306 silc_client_list_channel_private_keys and
3307 silc_client_free_channel_private_keys
3309 Affected file lib/silcclient/client_channel.c.
3311 * Added the support for the private keys in the channel message
3312 sending and encryption and in the message reception and
3313 decryption. Affected funtions are
3314 silc_client_send_channel_message and silc_client_channel_message.
3316 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Added SKE's key verify callback to the client library's
3319 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3321 * Removed the statement that server (or router) must send USERS
3322 command reply when joining to the channel so that the client
3323 knows who are on the channel. Instead, the client list and
3324 client's mode list is now sent in the JOIN command reply to the
3325 client who joined channel. This is better solution.
3327 * Added function silc_server_get_users_on_channel and function
3328 silc_server_save_users_on_channel to the silcd/server.[ch].
3330 * Removed function silc_server_command_send_users from the
3333 * Do not show topic on the client library anymore. The topic is
3334 sent in the command reply notify to the application and the
3335 application must show the topic now.
3337 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Added client searching by nickname hash into the IDENTIFY and
3340 WHOIS commands in the server as they were clearly missing from
3341 them. Affected file is silcd/command.c.
3343 * Fixed a bug in private message receiving in the client library.
3344 The remote ID was freed and it wasn't supposed, now it is
3347 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Minor fix to the channel payload; allocate the data area, as it
3350 needs to be of specific length.
3352 * If the key agreement port is zero then the operating
3353 system will define the bound port. Affected files are
3354 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3356 * Added new function silc_channel_payload_decrypt into the file
3357 lib/silccore/silcchannel.[ch].
3359 * Moved the channel message etc, check from silc_packet_decrypt
3360 to applications. The library calls now a generic
3361 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3362 when the packet is either normal or special. This was done to
3363 allow more wide range of checking that was not allowed when
3364 the code was in library. Now applications can do virtually any
3365 checks to the packet and return to the library the decision how
3366 the packet should be processed. Affected files are
3367 lib/silccore/silcpacket.[ch].
3369 Added silc_server_packet_decrypt_check to the server and
3370 silc_client_packet_decrypt_check to the client library.
3372 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3373 to send with specified source and destination information.
3375 * Channel message delivery between routers was broken after the
3376 channel key distribution was fixed earlier. The channel key
3377 was used be to distributed to other routers as well which is not
3378 allowed by the protocol. Now this is fixed and channel keys
3379 really are cell specific and the channel message delivery between
3380 routers comply with the protocol specification.
3382 * Fixed various commands in server to check also the global list
3383 for the channel entry and not just the local list. The affected
3384 file silcd/command.c.
3386 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Added assert()s to buffer formatting and unformatting routines
3389 to assert (if --enable-debug) when error occurs. Affected
3390 file: lib/silcutil/silcbuffmt.c.
3392 * Changed to auto-reconnect to check whether the remote host is
3393 router and register the re-connect timeout if it is. It used
3394 to check that whether we are normal server, but router must do
3395 auto-reconnect with another router as well. Affected file
3398 * Removed the [<key len>] option from CMODE command as the cipher
3399 name decides the key length, nowadays. See the defined ciphers
3400 from the protocol specification.
3402 * Added [<hmac>] option to the CMODE command to define the HMAC
3403 for the channel. Added SILC_CMODE_HMAC channel mode.
3405 * Added [<hmac>] option for the JOIN command so that user can
3406 select which HMAC is used to compute the MACs of the channel
3409 * Added Hmac field to the Channel Message Payload. The integrity
3410 of plaintext channel messages are now protected by computing
3411 MAC of the message and attaching the MAC to the payload. The
3412 MAC is encrypted. Now, it is clear that this causes some
3413 overhead to the size of the packet but rationale for this is that
3414 now the receiver can verify whether the channel message decrypted
3415 correctly and also when private keys are set for the channel the
3416 receiver can decrypt the packet with several keys and check from
3417 the MAC which key decrypted the message correctly.
3419 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3420 lib/silccrypt/silccipher.[ch].
3422 * Added silc_hash_len to return the digest length into the
3423 lib/silcrypt/silchash.[ch].
3425 * Rewrote parts of Silc Channel Payload interface in the
3426 lib/silccore/silcchannel.[ch]. The encode function now also
3427 encrypts the packet and parse function decrypts it.
3429 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Fixed a minor formatting bug in the SKE's key material processing.
3432 It actually might have processed the keys wrong way resulting
3435 * Redefined the mandatory HMAC algorithms and added new algorithms.
3436 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3437 and hmac-md5 truncated to 96 bits. The mandatory is now
3438 hmac-sha1-96. Rest are optional (including the one that used
3439 to be mandatory). Rationale for this is that the truncated HMAC
3440 length is sufficient from security point of view and can actually
3441 make the attack against the HMAC harder. Also, the truncated
3442 HMAC causes less overhead to the packets. See the RFC2104 for
3445 * Added new [hmac] configuration section. The SKE used to use
3446 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3447 is of course wrong. The official names that must be proposed in
3448 the SKE are the ones defined in the protocol specification
3449 (hmac-sha1-96 for example). The user can configure any hmac
3450 using any hash function configured in the [hash] section. At
3451 least, the mandatory must be configured.
3453 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3455 * Added HMAC list to the SKE proposal list. It has now both
3456 hash algorithm list and HMAC list. This makes the protocol
3457 incompatible with previous versions. The SKE now seems to work
3458 the way it is supposed to work, for the first time actually.
3460 * Defined plain Hash algorithms to the protocol specification.
3463 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Implemented support for key agreement packets into the server.
3466 Added functions silc_server_key_agreement and
3467 silc_server_send_key_agreement. Other than these functions,
3468 server has nothing to do with this packet.
3470 * Added support for private message key packets into the server.
3471 Added functions silc_server_private_message_key and
3472 silc_server_send_private_message_key.
3476 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3477 called in the protocol's final callback instead in the END
3478 protocol state. This makes a little more sense and in the same
3479 time in client we can use the same protocol routines for normal
3480 key exchange and to key agreement packet handling as well.
3482 * Added to both client's and server's KE protocol context the
3483 SilcSKEKeyMaterial pointer to save the key material. We will
3484 bring the key material to the protocol's final callback by doing
3485 this. The final callback must free the key material.
3487 * Added SKE's packet_send callback into client's KE protocol
3488 context so that the caller can choose what packet sending function
3489 is used. This way we can use different packet sending when
3490 doing normal SKE when doing key agreement packet handling (in
3491 the key agreement packet handling we do not want to encrypt
3494 * Implemented the responder side of the key agreement routines
3495 in the client. The client can now bind to specified port and
3496 accept incoming key negotiation. The key material is passed
3497 to the application after the protocol is over.
3499 * Implemented the processing of incoming Key Agreement packet
3500 in the client. Added function silc_client_key_agreement to
3503 * Implemented the intiator side of the key agreement routines
3504 in the client. The client can now initiate key agreement with
3505 another remote client. The key material is passed to the
3506 application after the protocol is over.
3508 * Created client_keyagr.c to include all the key agreement
3511 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3512 SILC_TASK_CALLBACK except that it is not static.
3514 * Created client_notify.c and moved the Notify packet handling
3515 from the client.[ch] into that file.
3517 * Created client_prvmsg.c and moved all private message and
3518 private message key routines from the client.[ch] into that file.
3520 * Create client_channel.c and moved all channel message and
3521 channel private key routines from the client.[ch] into that file.
3523 * Changed silc_client_get_client_by_id_resolve to resolve with
3524 WHOIS command instead of IDENTIFY command, in the file
3525 lib/silclient/idlist.c.
3527 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Implemented the SKE's responder side to the Client library.
3531 * When FAILURE is received to the protocol do not trust it
3532 blindly. Register a timeout to wait whether the remote closes
3533 the connection as it should do it, only after that process the
3534 actual failure. This was changed to both client and server.
3536 * Added client_internal.h to include some of the structures
3537 there instead of client.h in lib/silcclient/.
3539 * Added function silc_task_unregister_by_callback to unregister
3540 timeouts by the callback function.
3542 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Some "Incomplete WHOIS info" errors has been appearing on the
3545 log files. Took away the entry->userinfo check from WHOIS
3546 reply sending. The entry->userinfo is now " " if client did not
3547 provide one. I thought this was fixed earlier but something
3548 is wrong still. Let's see if the error still appears.
3550 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Fixed a minor bug in the login when the channel key is
3553 re-generated in the server. It used to generate the key in
3554 wrong order and thus caused problems in the channel traffic.
3556 * Fixed a minor bug in channel key distsribution after
3557 KICK command. The key was not sent to the router even though
3560 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added silc_ske_process_key_material_data as generic routine
3563 to process any key material as the SILC protocol dictates. The
3564 function is used by the actual SKE library but can be used by
3565 applications as well. This relates to the private message keys
3566 and the channel private keys since they must be processed the
3567 same way the normal SILC session keys. The protocol dictates
3568 this. Affected files: lib/silcske/silcske.[ch].
3570 Added also silc_ske_free_key_material to free the
3571 SilcSKEKeyMaterial structure.
3573 * Defined silc_cipher_set_key function to set the key for
3574 cipher without using the object's method function. The affected
3575 files: lib/silccrypt/silccipher.[ch].
3577 * Implemented silc silc_client_add_private_message_key,
3578 silc_client_add_private_message_key_ske,
3579 silc_client_del_private_message_key,
3580 silc_client_list_private_message_keys and
3581 silc_client_free_private_message_keys functions in the
3584 Added functions silc_client_send_private_message_key to send
3585 the Private Message Key payload and silc_client_private_message_key
3586 to handle incoming Private Message Key payload.
3588 * Added Cipher field to the Private Message Key payload to set
3589 the cipher to be used. If ignored, the default cipher defined
3590 in the SILC protocol (aes-256-cbc) is used.
3592 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3594 * Removed lib/silcclient/ops.h file.
3596 Redefined parts of the SILC Client Library API. Created new
3597 file silcapi.h that deprecates the ops.h file and defines the
3598 published Client Library API. Defined also private message key
3599 API and channel private key API into the file.
3601 This is the file that the application must include from the
3602 SILC Client Library. Other files need not be included by
3603 the application anymore.
3605 * Added new key_agreement client operation callback and also
3606 defined the Key Agreement library API for the application.
3608 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3611 is used by clients to request key negotiation between another
3612 client in the SILC network. If the negotiation is started it
3613 is performed using the SKE protocol. The result of the
3614 negotiation, the secret key material, can be used for example
3615 as private message key.
3617 Implemented the Key Agreement payload into the files
3618 lib/silccore/silauth.[ch].
3620 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Redefined ciphers for the SILC protocol. Added some new ciphers
3623 and defined the key lengths for the algorithms. Changed the
3624 code accordingly. The default key length is now 256 bits.
3626 * Fixed SKE key distribution function silc_ske_process_key_material
3627 when the key length is more than 128 bits. The default key
3628 length in SILC is now 256 bits.
3630 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3631 to indicate unsupported algorithm.
3633 * Renamed rijndael.c to aes.c and all functions as well.
3635 * Fixed a long standing channel key setting bug in client library.
3636 Weird that it has never surfaced before.
3638 * Fixed bug in channel deletion. If the entire channel is removed
3639 then it must also delete the references of the channel entry
3640 from the client's channel list as the client's channel entry and
3641 the channel's client entry share same memory.
3643 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Implemented CONNECT and SHUTDOWN commands in the client.
3647 * Implemented CLOSE command to the client.
3649 * Added the function silc_idlist_find_server_by_name into the
3650 files silcd/idlist.[ch].
3652 Added the function silc_idlist_find_server_by_conn into the
3653 files silcd/idlist.[ch].
3655 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * DIE command was renamed to SHUTDOWN. Updated the both code
3660 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3661 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3663 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3666 * Added function silc_server_create_connection function to create
3667 connection to remote router. My server implementation actually
3668 does not allow router to connect to normal server (it expects
3669 that normal server always initiates the connection to the router)
3670 so the CONNECT command is only good for connecting to another
3673 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3676 or some other client was kicked from the channel.
3678 Implemented the handling of the notify type to both client
3681 Implemented silc_server_send_notify_kicked to send the KICKED
3682 notify. It is used to send it to the server's primary router.
3684 * Implemented the KICK command into server and client.
3686 * Added `query' argument to the silc_idlist_get_client function
3687 to indicate whether to query the client from server or not if
3690 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3691 to indicate that the client is not channel founder.
3695 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Removed the rng context from SilcPacketContext structure and
3698 changed that the packet routine uses the Global RNG API.
3700 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Added support for quit message that client can "leave" on the
3703 channel when it quits the SILC. It is ditributed inside the
3704 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3706 Added silc_server_free_client_data that will take the
3707 signoff message as argument.
3709 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3711 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Updated parts of the protocol specification to keep it up
3716 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3719 payloads in one packet.
3721 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3722 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3723 use now the new List flag.
3725 * Also deprecated the following packet types: REPLACE_ID,
3726 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3728 * Added list support for Notify packet in server.
3730 * Added silc_server_send_notify_channel_change to send the
3731 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3732 the silc_server_send_replace_id.
3734 * Added silc_server_send_notify_nick_change to send the
3735 NICK_CHANGE notify type. Deprecates the function
3736 silc_server_send_replace_id.
3738 * Added silc_server_send_notify_join to send the JOIN notify type.
3739 Deprecates the function silc_server_send_new_channel_user.
3741 * Added silc_server_send_notify_leave to send LEAVE notify type.
3742 Deprecates the function silc_server_send_remove_channel_user.
3744 * Added silc_server_send_notify_cmode and
3745 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3746 types. Deprecates the silc_server_send_set_mode function.
3748 * Added SERVER_SIGNOFF notify type to indicate that server has
3749 quit. This means that all clients on the channel from that
3750 server will drop. This can be also used when netsplit happens.
3752 Deprecated REMOVE_ID packet type since it is not needed anymore
3755 Added silc_server_send_notify_server_signoff to send the
3756 SERVER_SIGNOFF notify type. Deprecates the function
3757 silc_server_send_remove_id.
3759 Added also silc_server_send_notify_signoff to send the
3760 SIGNOFF notify type.
3762 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3763 SILC protocol from this day on. Changed the protocol
3764 specification as well.
3766 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3767 notify type. It is used between routers to notify about
3768 topic changes on a channel.
3770 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3773 * Partly updated the protocol specification to comply with the
3774 changes now made. It is still though a bit outdated.
3776 * The JOIN notify type now takes one extra argument <Channel ID>.
3777 The packet used to be destined to the channel but now the
3778 JOIN type may be sent as list thus it is impossible to
3779 destine it to any specific channel. By adding this argument
3780 it is again possible.
3782 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Added CREDITS file. The CHANGES and CREDITS file will appear
3785 in the distribution as well.
3787 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3790 types in the server's silcd/packet_receive.c.
3792 * Implemented CMODE and CUMODE to work in router environment.
3794 * Fixed minor encoding and decoding buglet from the
3795 lib/silccore/silcmode.c.
3797 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3800 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3802 * Changed all SilcConfigServer* and silc_config_server* to
3803 SilcServerConfig* and silc_server_config*, respectively.
3806 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Associated the ID (client or server ID) to the Authentication
3809 Payload to avoid any possibility of forging. Updated the
3810 protocol specification and the code accordingly.
3812 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * The RSA key length is now save to the RsaKey context in the
3815 key generation process in lib/silccrypt/rsa.c. The key length
3816 is now used to figure out the maximum size of the block allowed
3817 to be encrypted/signed.
3819 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3820 is equivalent to the silc_mp_mp2bin but does not allocate any
3823 * Changed silc_mp_mp2bin API to take length argument. If it is
3824 non-zero then the buffer is allocated that large. If zero, then
3825 the size is approximated using silc_mp_sizeinbase, which however
3828 * Created Global RNG API which is global RNG that application can
3829 initialize. After initializing, any routine anywhere in the
3830 code (including library) can use RNG without allocating a new
3831 RNG object. This was done to allow this sort of use of the
3832 RNG in code that has no chance to allocate RNG object. All
3833 applications currently allocate this and many routines in the
3834 library use this. Affected file lib/silccrypt/silcrng.[ch].
3836 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3837 it to use the Global RNG API.
3839 * Defined Authentication Payload into protocol specification that
3840 is used during SILC session to authenticate entities. It is
3841 used for example by client to authenticate itself to the server
3842 to obtain server operator privileges.
3844 Implemented this payload into the lib/silccore/silcauth.[ch].
3845 Implemented also routines for public key based authentication
3846 as the new protocol specification dictates.
3848 Moved definitions of different authentication methods from
3849 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3851 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3852 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3853 silc_pkcs_verify_with_hash functions into the file
3854 lib/silccrypt/silcpkcs.[ch].
3856 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * The client entry's userinfo pointer must be always valid.
3859 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3860 will fail since it requires the userinfo. Now, the userinfo
3861 is allocated as "" if actual userinfo does not exist. Actually,
3862 it must exist and it is totally Ok to drop client connections
3863 that does not announce the userinfo. However, we will make
3864 this workaround for now.
3866 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3867 to return the remote port by socket.
3869 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3872 SILC_SERVER_PENDING_EXEC and added an new macro
3873 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3874 data or when error occurs while processing the pending command.
3876 Added new argument `destructor' into silc_server_command_pending
3877 and to the SilcServerCommandPending object. This destructor is
3878 now called after calling the pending callback or if error occurs
3879 immediately. If error occurs the actual pending callback won't
3880 be called at all - only the destructor. The destructor may be
3881 NULL if destructor is not needed.
3883 All this applies for client library code as well. Similar
3884 changes were made there as well for the pending commands.
3886 In the client, the application must now allocate the
3887 SilcClientCommandContext with the silc_client_command_alloc
3890 * Added reference counter to the SilcServerCommandContext. Added
3891 function silc_server_command_alloc and silc_server_command_dup
3894 Same type of functions added to the client library for the same
3897 * Removed the cmd_ident from IDListData away since it is now
3898 global for all connections. It is the command identifier used
3899 in command sending and with pending commands. The affected file
3902 * Added reference counter to the SilcSocketConnection objecet to
3903 indicate the usage count of the object. The object won't be
3904 freed untill the reference counter hits zero. Currently only
3905 server uses this, and client ignores it. The client must be
3906 set to use this too later. The affected files are
3907 lib/silccore/silcsockconn.[ch]. Added also the function
3908 silc_socket_dup to increase the reference counter.
3910 This was mainly added because it is possible that the socket
3911 is removed underneath of pending command or other async
3912 operation. Now it won't be free'd and proper DISCONNECTING
3913 flags, etc. can be set to avoid sending data to connection that
3914 is not valid anymore.
3916 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3917 the connection. After that it sets SILC_SET_DISCONNECTED.
3918 It is, however, possible that the socket data is not still freed.
3919 The silc_server_packet_process now checks that data is not
3920 read or written to connection that is DISCONNECTED. The socket
3921 get's freed when the reference counter hits zero.
3923 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Changed the client operation API: channel_message operation's
3926 `sender' is now the client entry of the sender, not the nickname
3927 and the `channel' is the channel entry, not the channel name.
3929 In the private_message operation the `sender' is now also the
3930 client entry of the sender not the nickname.
3932 Affected file is lib/silcclient/ops.h and all applications
3933 using the client operations.
3935 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Moved the calling of ops->connect() from connect_to_server_final
3938 into receive_new_id functin since that is the point when the
3939 client is actually allowed to send traffic to network. The
3940 affected file is lib/silcclient/client.c.
3942 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3945 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3946 (if needs broadcasting) instead of broadcasting the packets one
3947 by one which would make a burst in the network traffic.
3949 * Added `broadcast' argument to the functions in silcd/server.[ch]
3950 silc_server_create_new_channel[_with_id] to indicate whether
3951 to send New Channel packet to primary router.
3953 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Added new function into the silcd/server.[ch] files:
3956 silc_server_create_new_channel_with_id to create new channel with
3957 already existing Channel ID.
3959 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3960 lib/silccore/silcpacket.h. This packet is used t send list of
3961 Set Mode payloads inside one packet. Server uses this to set
3962 the modes for the channels and clients on those channels, that it
3963 announced to the router when it connected to it. The protocol
3964 specification has been updated accordingly.
3966 * The silc_server_new_channel did not handle the packet coming
3967 from normal server as it normally does not send that. However,
3968 when it announces its channels it does send it. Implemented
3969 the support for that.
3971 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3972 into the file lib/silccore/id.h.
3974 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Fixed memory leaks in the functions silc_idlist_del_client,
3977 silc_idlist_del_channel and silc_idlist_del_server in the file
3978 silcd/idlist.c. All of those leaked like a sieve.
3980 * Fixed some small memory leaks in the client's function
3981 silc_client_notify_by_server.
3983 * Added functions into silcd/server.c: silc_server_announce_clients,
3984 silc_server_announce_channels and silc_server_announce_server.
3985 These functions are used by normal and router server to announce
3986 to its primary router about clients, channels and servers (when
3987 router) that we own. This is done after we've connected to the
3990 These functions effectively implements the following packet types:
3991 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3992 and SILC_PACKET_NEW_ID_LIST.
3994 * Added new functions into the silcd/packet_receive.[ch]:
3995 silc_server_new_id_list, silc_server_new_channel_list and
3996 silc_server_new_channel_user_list to handle the incoming
3997 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3999 * Added support of changing Channel ID in the function
4000 silc_server_replace_id. If the server that announces a channel
4001 to the router already exists in the router (with same name but
4002 with different Channel ID), router is responsible to send
4003 Replace ID packet to the server and force the server to change
4004 the Channel ID to the one router has.
4006 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4007 client that the Channel ID has been changed by the router. The
4008 normal server sends this to the client. Client must start using
4009 the new Channel ID as the channel's ID.
4011 Implemented handling of this new type into lib/silcclient/client.c
4012 into the function silc_client_notify_by_server.
4014 * Added new function silc_idlist_replace_channel_id into the files
4015 silcd/idlist.[ch] to replace the Channel ID.
4017 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4019 * Call silc_server_command_identify_check always when processing
4020 the IDENTIFY command in silcd/command.c
4022 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4025 send keepalive packets. The packet can be sent by clients,
4026 servers and routers.
4028 Added function silc_socket_set_heartbeat into the file
4029 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4030 If not set, the heartbeat is not performed. The actual
4031 heartbeat is implemented in the low level socket connection
4032 library. However, application is responsible of actually
4035 Added silc_server_send_heartbeat to send the actual heartbeat
4036 packet into silcd/packet_send.[ch]. Server now performs
4037 keepalive with all connections.
4039 * Added silc_task_get_first function into lib/silcutil/silctask.c
4040 to return the timeout task with shortest timeout. There was a bug
4041 in task unregistration that caused problems. TODO has been
4042 updated to include that task system must be rewritten.
4044 * The client library will now resolve the client information when
4045 receiving JOIN notify from server for client that we know but
4046 have incomplete information.
4048 * Rewrote parts of silc_server_remove_from_channels and
4049 silc_server_remove_from_one_channel as they did not remove the
4050 channel in some circumstances even though they should've.
4052 * Encryption problem encountered in server:
4054 The LEAVE command used to send the Channel Key packet to the
4055 router immediately after generating it. However, the code
4056 had earlier sent Remove Channel user packet but not immediately,
4057 ie. it was put to queue. The order of packets in the router
4058 was that Channel Key packet was first and Remove Channel User
4059 packet was second, even though they were encrypted in the
4060 reverse order. For this reason, MAC check failed. Now, this
4061 is fixed by not sending the Channel Key packet immediately but
4062 putting it to queue. However, this is more fundamental problem:
4063 packets that are in queue should actually not be encrypted
4064 because packets that are sent immediately gets encrypted
4065 actually with wrong IV (and thus MAC check fails). So, packets
4066 that are in queue should be encrypted when they are sent to
4067 the wire and not when they put to the queue.
4069 However, the problem is that the current system has not been
4070 designed to work that way. Instead, the packet is encrypted
4071 as soon as possible and left to the queue. The queue is then
4072 just purged into wire. There won't be any fixes for this
4073 any time soon. So, the current semantic for packet sending
4076 o If you send packet to remote host and do not force the send
4077 (the packet will be in queue) then all subsequent packets to the
4078 same remote host must also be put to the queue. Only after the
4079 queue has been purged is it safe again to force the packet
4082 o If you send all packets immediately then it safe to send
4083 any of subsequent packets through the queue, however, after
4084 the first packet is put to queue then any subsequent packets
4085 must also be put to the queue.
4087 Follow these rules and everything works fine.
4089 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Added new function silc_server_remove_clients_by_server to
4092 remove all client entries from ID list when the server connection
4093 is lost. In this case it is also important to invalidate all
4094 client entires as they hold the invalid server entry. This
4095 fixes fatal bug when server has lost connection and will reconnect
4098 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Made some sanity checks to silc_server_daemonise like to check
4101 whether the requested user and group actually exists.
4103 * Added sanity check to SKE's silc_ske_responder_finish to check
4104 that the public and private key actually is valid.
4106 * Invalidate the client's nickname when receiving Replace ID
4107 packet and the Client ID is being replaced. This means that the
4108 server will query the nickname if someone needs it (client)
4111 * Sort the ID Cache in client library when the ID Cache data
4112 has changed (needs sorting).
4114 * Do not allow for SILC client to create several connections to
4115 several servers. The client does not support windows right now
4116 and generating multiple connections causes weird behaviour.
4118 Irssi-silc client does support windows and can handle several
4119 connections without problems, see: www.irssi.org and SILC plugin.
4121 * Fixed some places where client was added to the IDList. The
4122 rule of thumb is following (in order to get everything right):
4123 If the client is directly connected local client then the
4124 `connection' argument must be set and `router' argument must be
4125 NULL to silc_idlist_add_client function. If the client is not
4126 directly connected client then the `router' argument must
4127 bet set and the `connection' argument must be NULL to the
4128 silc_idlist_add_client function.
4130 * The funtion silc_server_packet_send_local_channel actually did
4131 not check whether the client was locally connected or not. It
4132 does that now. Fixed a bug related to LEAVE command.
4134 * Fixed Remove Channel User payload parsing bug in server's
4135 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4137 * The server's silc_server_save_channel_key now checks also the
4138 global ID list for the channel as it might not be in the local
4139 list. Fixed a bug related to LEAVE command.
4141 * Is this the end of the [<unknown>] buglet that has been lurking
4142 around for a long time? A little for loop fix in server's
4143 silc_server_command_whois_parse that is used by both IDENTIFY
4144 and WHOIS command. At least, this was a clear bug and a cause
4145 of one type of [<unknown>] buglet.
4147 * WHOIS and IDENTIFY commands call the function
4148 silc_server_command_[whois/identify]_check function even if
4149 we are not router server.
4151 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Added --with-gmp configuration option. If set the GMP
4154 is always compiled in the SILC source tree. If not set then
4155 it is checked whether the system has the GMP3 installed. If
4156 it has then the GMP won't be compiled (the system's headers
4157 and library is used), if it doesn't have it then the GMP is
4158 compiled in the SILC source tree.
4160 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Changed RSA private exponent generation to what PKCS #1
4163 suggests. We try to find the smallest possible d by doing
4164 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4165 not security fix but optimization.
4167 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Added new config entry [Identity] to fork the server and run
4170 it as specific user and group. A patch from Bostik.
4172 * Imported Dotconf configuration library into lib/dotconf.
4173 This will be used to create the SILC configuration files later.
4174 It will appear in the distsribution after this commit.
4176 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * A big code auditing weekend happening. Auditing code for
4179 obvious mistakes, bugs and errors. Also, removing any code
4182 Removed files for being obsolete:
4184 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4185 inline in the file lib/silcutil/silcbuffer.h)
4187 o lib/silcutil/silcbufutil.c (the header has inline versions)
4189 Changed code to fix possible error conditions:
4191 o The buffer formatting routines now check that the destination
4192 buffer really has enough space to add the data. This applies for
4193 both buffer formatting and unformatting
4194 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4195 unformatting was changed to accomodate following rules:
4196 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4197 sent to the function while XXX_*STRING will not allocate or copy
4198 the data into the buffer. Instead it sets the pointer from the
4199 buffer into the pointer sent as argument (XXX_*STRING used to
4200 require that the pointer must be allocated already). This change
4201 makes this whole thing a bit more consistent and more optimized
4202 (note that the data returned in the unformatting with XXX_*STRING
4203 must not be freed now). The routines return now -1 on error.
4205 o Tried to find all code that use buffer_format and buffer_unformat
4206 and added return value checking to prevent formatting and
4207 especially unformatting errors and possible subsequent fatal
4210 o Changed ske->x and ske->KEY to mallocated pointers in
4211 lib/silcske/silcske.h. Fixed possible data and memory leak.
4213 o Added return value checking to all *_parse* functions. Fixed
4214 many memory leaks as well.
4216 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4217 so that buffer overflows would not happen. All code now also
4218 checks the return value as it can fail.
4220 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Added reconnection support to server if the normal server looses
4223 its connection to the router (for example if router is rebooted).
4224 The server performs normal reconnection strategy implemented
4225 to the server. Affected file silcd/server.c.
4227 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Added new packet type SILC_PACKET_SET_MODE that is used to
4230 distribute the information about changed modes (for clients,
4231 channels and clients channel modes) to all routers in the
4232 network. Updated the protocol specification accordingly.
4234 Added functions into silcd/packet_send.c and
4235 silcd/packet_receive.c: silc_server_send_set_mode,
4236 silc_server_set_mode.
4238 Added new files silcmode.[ch] into lib/silccore that implements
4239 the encoding and decoding of Set Mode Payload. Added new type
4240 SilcSetModePayload. Moved the definitions of different modes
4241 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4243 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Oops, a little mistake in server's connection authentication
4246 protocol. The protocol is not ended with FAILURE but with
4247 SUCCESS if the authentication is Ok. :) Affected file is
4250 * Implemented NICK_CHANGE notify handling in server in the file
4251 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4252 the local clients on the channel. After the changing nickname
4253 in router environment snhould work and the [<unknown>] nickname
4254 should appear no more.
4256 The silc_server_replace_id function that receives the Replace ID
4257 payload now sends the NICK_CHANGE notify type also in the file
4258 silcd/packet_receive.c
4260 * Changed WHOIS and IDENTIFY command to support the maximum amount
4261 of arguments defined in protocol specs (3328 arguments). This
4262 fixed a bug that caused problems when there were more than three
4265 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Added extra parameter, command identifier, to the
4268 silc_client_send_command so that explicit command identifier
4271 Changed that ID list routines uses specific command identifier
4272 when sending WHOIS/IDENTIFY requests to the server so that they
4273 can be identified when the reply comes back.
4275 Affected files lib/silcclient/command.[ch],
4276 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4278 * Added `sender' argument to silc_server_packet_send_to_channel
4279 to indicaet the sender who originally sent the packet to us
4280 that we are now re-sending. Ignored if NULL. Affected file
4281 silcd/packet_send.[ch].
4283 * Added some server statistics support in silcd/server_internal.h
4284 SilcServerStatistics structure and around the server code. Also
4285 send some nice statistics information when client is connecting
4288 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Fixed channel ID decoding in server's JOIN command reply in
4291 silcd/command_reply.c
4293 * Fixed braodcasting of replace ID payload to not to send it if
4294 we are standalone server in silcd/packet_receive.c.
4296 * Fixed all channel message sending routines to not to send
4297 packets to clients that has router set, since they are routed
4298 separately in the same function earlier. Affects file
4299 silcd/packet_send.c and all channel packet sending functions.
4301 * In USERS reply, res_argv[i] are not allocated, the table
4302 is allocated. Thus changed that free the table, not its
4305 * In server's whois_check and identify_check if the client is
4306 locally connected do not send any WHOIS commands - they are not
4309 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Fixed some minor bugs in client when sending WHOIS command. The
4312 arguments was in wrong order.
4314 * Removed statis function add_to_channel from server in
4315 silcd/command.c that was previously used with the joining but
4318 * Tested USERS command in router environment successfully with two
4319 routers, two servers and two clients.
4321 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Reorganized the USERS command and command reply in client library
4324 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4325 When the command is given by user we register a pending command
4326 callback that will reprocess the command after the reply has been
4327 received from the server. When reprocessing the packet we then
4328 display the information. Thus, the USERS information is displayed
4329 now in the command callback instead of in the command reply
4330 callback. The processing of the command is same as previously
4331 when server has sent the command reply in the JOINing process.
4333 * Added to USERS command in silcd/command_reply.c to join the client,
4334 we didn't use to know about, to the channel after we've created
4335 a client entry for it. Also, for clienet we did know already still
4336 check whether it is on the channel or not and add it if not.
4338 * Removed silc_server_command_join_notify as the function and its
4341 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Changed the client's pending command handling to the same as the
4344 server's pending command handling. It is also now possible to
4345 execute command reply functions from other command reply
4346 function as the function callbacks for commands and command
4347 replies are one and same. The pending commands are not static
4348 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4349 in client connection context. Thus, pending commands are server
4350 connection specific as it is convenient.
4352 Changed the function silc_client_command_pending and
4353 silc_client_command_pending_del and added new function
4354 silc_client_command_pending_check. Removed the
4355 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4358 * Added cmd_ident, current command identifier, to the client
4359 connection context in lib/silcclient/client.h to keep track on
4360 command identifiers used in command sending. Client's command reply
4361 function handling now supports the mandatory command identifiers.
4363 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4364 funtions in client to fully support pending command callbacks.
4366 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4367 as one of the arguments to the application in the command reply
4370 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4371 before first releasing SILC but came back. Now it is removed again
4372 and should come back nomore. The FORWARDED flag was used only
4373 by the JOINing procedure by forwarding the command packet to router.
4374 Now, the JOINing procedure has been changed to more generic (due
4375 to various router environment issues) and FORWARDED is not needed
4376 anymore for anything. The protocol specification is yet to be
4379 Now, removed silc_server_packet_forward from server and the flag
4380 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4382 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Renamed NAMES command to USERS command. The NAMES was named that
4385 due to historical reasons. Now it is renamed. Also, rewrote
4386 parts of the USERS command. The nickname list is not sent anymore
4387 by the server. Only Client ID and mode lists are sent in the USERS
4388 command. Changed this also to the protocol specification.
4390 The client now resolves the names and stuff after it receives
4391 the USERS list from the server when joining to the channel.
4393 * WHOIS and IDENTIFY commands has been changed to support multiple
4394 Client ID's per command. One can now search for multiple users
4395 in the network by sending only one WHOIS or IDENTIFY command.
4396 Changed the code and the protocol specifications.
4398 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4399 uses silc_server_command_whois_parse to parse the request. */
4401 * If normal server, do not parse the WHOIS and IDENTIFY requests
4402 before sending it to the router. Saves some time.
4404 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Fixed JOIN command on client library. Wrong number of arguments
4407 used to crash the client.
4409 * Added silc_server_channel_has_global function to check whether
4410 channel has global users or not.
4412 * Added silc_server_channel_has_local function to check whether channel
4413 has locally connected clients on the channel.
4415 * The silc_server_remove_from_one_channel now checks whether the
4416 channel has global users or not after given client was removed from
4417 the channel. It also checks whether the channel has local clients
4418 on the channel anymore. If it does not have then the channel entry
4419 is removed as it is not needed anymore.
4421 * The silc_server_notify now checks on JOIN notify whether the joining
4422 client is one of locally connected or global. If it is global then
4423 the channel has now global users on the channel and that is marked
4424 to the channel entry. Also, it now saves the global client to
4425 global list who is joining and JOINs it to the channel. This is
4426 for normal server, that is.
4428 Changed silc_server_send_notify_on_channel,
4429 silc_server_packet_relay_to_channel and
4430 silc_server_packet_send_to_channel check if we are normal server
4431 and client has router set (ie. global client) do not send the
4432 message to that client, as it is already routed to our router.
4434 * Implemented LEAVE notify type handling in silc_server_notify
4437 * Tested LEAVE command in router environment successfully. Tested
4438 with two routers, two servers and two clients.
4442 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4444 * Implemented SIGNOFF notify type handling in silc_server_notify
4447 * silc_server_remove_id now removes the client entry from all channels
4448 it has joined and thusly sends SIGNOFF notify type.
4450 * Rewrote the NAMES list generation in server by removing two excess
4451 loops. The lists are created now inside one loop.
4453 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * silc_server_remove_channel_user checks now also global list
4456 for channel and client.
4458 * silc_server_new_channel_user checks now both local and global
4459 list for channel and client. Fixed a bug in client id decoding.
4460 Used to decode wrong buffer.
4462 * silc_server_channel_message checks now both local and global
4463 list for channel entry.
4465 * Tested channel joining (hence JOIN) in router environment
4466 successfully. Tested with two routers, two servers and two
4469 * Tested channel message sending in router environment successfully.
4471 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added silc_server_save_channel_key into server.[ch] to save the
4474 received channel key in Channel Key payload processing. It is
4475 also used in JOIN command reply handling.
4477 Equivalent function silc_client_save_channel_key added into
4478 client.[ch] into client library.
4480 * Changed JOIN command reply to send information whether the channel
4481 was created or not (is existing already) and the channel key
4482 payload. Changed protocol specs accordingly.
4484 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4485 the request was sent by ID and not by nickname. Crashed on
4488 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4491 now correctly save the received data.
4493 * silc_server_free_sock_user_data now notifies routers in the
4494 network about entities leaving the network.
4496 At the same time implemented functions silc_server_remove_id
4497 and silc_server_send_remove_id to receive and send REMOVE_ID
4498 packets. The packet is used to notify routers in the network
4499 about leaving entities. The ID removed will become invalid in
4502 * Added function silc_idlist_del_server into server. Removes and
4503 free's server entry from ID list.
4505 * silc_server_private_message function now checks, if we are router,
4506 that the destination ID really is valid ID, naturally.
4508 * In router when NEW_ID packet is received (for new client) the
4509 hash of the Client ID is saved in the ID Cache but the
4510 client->nickname is set to NULL, instead of putting the hash
4513 IDENTIFY command now also checks that client->nickname must be
4514 valid. If it is not if will request the data from the server who
4515 owns the client. Added new function
4516 silc_server_command_identify_check.
4518 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4519 to set the command to already allocated Command Payload.
4521 * Tested private message sending in router environment with two
4522 routers, two servers and two clients. Fixed minor bugs and now
4525 * Fixed segfault from client's NAMES command. Used to crash if
4528 * Forwarded packets must not be routed even if it is not destined
4529 to the receiver. Changed server code comply with this.
4531 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added `require_reverse_mapping' boolean value to ServerParams
4534 structure. If TRUE (not default) the server will require that
4535 the connecting host has fully qualified domain name.
4537 If the reverse mapping is not required and hostname could not be
4538 found the IP address is used as hostname.
4540 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Implemented version string checking to both client and server.
4543 The check is incomplete currently due to the abnormal version
4544 strings used in development version of SILC.
4546 * Changed all command functions in server to use the new
4549 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Changed char *data to unsigned char *data in ID Cache system to
4552 support binary data as ID Cache data. Changed code to support
4553 binary data in lib/silccore/idcache.c.
4555 * Renamed silc_server_packet_relay_command_reply to
4556 silc_server_command_reply as it is normal packet receiving
4557 function. Rewrote the function to accept command replys for
4558 servers and not only for clients.
4560 * Mark remote router always as registered server if we are connecting
4561 to it. Otherwise, commands sent by the router to us are ignored.
4563 * All ID List find routines now returns the ID Cache Entry pointer
4564 as well if requested.
4566 * WHOIS command works now in router environment, tested with two
4567 routers, two servers and two clients.
4569 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4570 in router environment (as it is almost equivalent to WHOIS) but
4571 hasn't been tested thoroughly. Added new functions:
4573 silc_server_command_identify_parse
4574 silc_server_command_identify_send_reply
4575 silc_server_command_identify_from_client
4576 silc_server_command_identify_from_server
4578 * Disabled route cache adding because adding two different ID's with
4579 same IP replaces the old cache entry thus giving wrong route.
4580 The entry->router->connection is always the fastest route anyway
4581 so route cache may not be needed. Of course, new routes maybe
4582 established after receiving the ID when the entry->router->connection
4583 might not be anymore the most optimal.
4585 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Add route cache for received ID for fast routing.
4589 * Added silc_server_packet_route to route received packet on router
4590 that is not destined to us.
4592 * Renamed silc_server_get_route to silc_server_route_get.
4594 * Added id_string and id_string_len fields into SilcServer to
4595 include encoded ServerID for fast comparing without excess
4596 encoding of the ID's.
4598 * Cleaned up WHOIS command on server side. Added following static
4601 silc_server_command_whois_parse
4602 silc_server_command_whois_check
4603 silc_server_command_whois_send_reply
4604 silc_server_command_whois_from_client
4605 silc_server_command_whois_from_server
4607 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4608 arguments in command replies. All command functions should be
4609 updated to use this macro.
4611 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Minor typo fixes on command reply handling on server.
4615 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added silc_server_command_add_to_channel internal routine to add
4618 the client to the channel after router has created the channel and
4619 sent command reply to the server.
4621 * Added generic silc_server_send_command to send any command from
4624 * Use static buffer with ID rendering instead of duplicating data.
4626 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Fixed a channel user mode bug when joining to a channel server gave
4629 everybody channel founder rights, oops.
4631 * We mark ourselves as the router of the incoming server connection
4632 if we are router ourselves. This way we can check in some packet
4633 sending functions whether it is locally connected server. For
4634 incoming router connections we put NULL.
4636 * For router sending packets locally means now always sending the
4637 packet cell wide; to local clients and local servers. For normal
4638 server sending packet locally means sending it to only local
4641 * Fixed the JOIN command to really work in router environment. If the
4642 channel is created it is always created by the router. Router is
4643 also responsible of making the initial joining to the channel,
4644 sending JOIN notify to the sending server and distributing
4645 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4646 does not exist server doesn't do anything else but forward the
4647 command to the router which performs everything.
4649 * Added silc_server_send_channel_key function to send the Channel Key
4652 * Added silc_server_create_channel_key to create new channel key. The
4653 channel key is now re-generated everytime someone joins or leaves
4654 a channel, as protocol dictates. Note: channel->key_len is the
4657 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4660 packet_receive.[ch] to separate packet sending and receiving
4661 routines. The server.[ch] now includes everything else including
4662 actual packet processing (writing and reading data) and other
4665 Renamed silc_server_private_message_send_internal to
4666 silc_server_send_private_message. The routine is still though
4667 used only to relay private messages as server does not send
4668 private messages itself.
4670 Renamed silc_server_new_channel to silc_server_create_new_channel
4671 and added new function sicl_server_new_channel that handles the
4672 incoming New Channel packet. Added also new sending function
4673 silc_server_send_new_channel to send New Channel Payload.
4675 * Added new function silc_server_notify to process incoming notify
4676 packet to the server/router. Server may then relay the notify
4677 to clients if needed.
4679 * Added new function silc_server_new_channel_user to process incoming
4680 New Channel User packet. Router will redistribute the packet and
4681 send JOIN notify to its local clients and locally connected servers
4682 if needed. Normal server will send JOIN notify to its local client
4683 on same channel when received this packet. Added also corresponding
4684 sending function silc_server_send_new_channel_user to sent the
4687 * Added boolean route argument to send_notif_to_channel and
4688 packet_send_to_channel functions to attempt to route the packet
4689 if it is TRUE and send only locally if it is FALSE.
4691 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * silc_server_replace_id now broadcasts the received replace ID
4694 packet if it is not broadcast packet already. The router must
4695 broadcast to inform other routers about changed ID.
4697 * Added backpointer to server's router into SilcServer context in
4698 silcd/server_internal.h.
4700 * Fixed silc_server_packet_broadcast to send correct broadcast
4703 * The channel key is now distributed to the local client as soon
4704 as it is received from the router (in router environment) so that
4705 no other packet may be sent for the channel until client has
4708 * silc_server_remove_channel_user now broadcasts the received
4709 Remove Channel User packet if it is not broadcast packet already.
4710 The router must broadcast to inform other routers about removed
4713 * Added users field into SilcPacketContext that is a reference count
4714 of the context. One can increase the reference count by calling
4715 silc_packet_context_dup which is now changed to just increase the
4716 reference count instead of duplicating the data. The reference
4717 count is decresed by calling silc_packet_context_free that will
4718 free the data after the reference count hits zero.
4720 For now on the packet context and everything allocated into it
4721 (including the raw packet from network) must be freed by calling
4722 the new silc_packet_context_free function. Added also new function
4723 silc_packet_context_alloc that must be used now to allocate the
4724 context. This also means that if a routine is asynchronous from
4725 silc_[client/server]_packet_parse_type the packet context must
4726 be duplicated by calling silc_packet_context_dup. Otherwise it
4727 gets free'd after silc_[client/server]_packet_parse_type returns.
4728 Also, one must remember that if packet is duplicated then its
4729 reference count must be decresed by calling the free function as
4730 many times as it was duplicated.
4732 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4733 from both client and server.
4735 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Made joining to a channel working in router environment.
4739 * Cleaned up JOIN command on server side and create function
4740 silc_server_command_join_channel internal routine to make the
4743 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Changed silc_command_pending list to SilcDList. Also, added
4746 `ident' field to SilcServerCommandPending structure to identify
4747 the reply and to call correct callback.
4749 Added silc_server_command_pending_check function to replace the
4750 corresnponding macro. The silc_command_pending list is not
4753 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4754 to set identifier to previously allocated Command Payload. It
4755 is used to set identifier for command when resending Command
4758 * Added silc_command_payload_encode_payload to encode Command
4759 Payload buffer from SilcCommandPayload structure.
4761 * Added silc_argument_payload_encode_payload to encode Argument
4762 payload buffer from SilcArgumentPayload structure.
4764 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Changed WHOIS command to support router connection on server side.
4767 The whois request is always sent to router unless the server is
4768 standalone server. After server has received the reply from the
4769 router will it send the reply to the client.
4771 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4772 broadcast received broadcast packet. The function is used only
4773 by router. The broadcast packet is always sent to the router's
4776 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4777 render given ID to printable string, for log files for example.
4779 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Made basic router to router connections working. At least they
4782 can now connect to each other but nothing really works the way
4783 they are supposed - yet.
4785 * Added new initiator token to RouterConnection configuration
4786 file in silcd/serverconfig.[ch]. It is used to tell whether we
4787 are the initiator to the remote router or whether we'll expect
4788 the other end to connect.
4790 * Moved registering of listener task to silc_server_init, hence
4791 the server starts listenning as soon as it is run, even if it
4792 does not have connections to other routers. Let's see how well
4795 * Changed default connection retry timeouts for more suitable in
4798 * Removed cipher and such arguments from silc_idlist_add_client
4799 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4800 Added new function silc_idlist_add_data to add the keys and stuff
4803 * Added SilcIDListData structure and added it to SilcClientEntry
4804 and SilcServerEntry as their first field in the structure. This
4805 way we can explicitly cast the ID entries to the SilcIDListData
4806 structure and get common data for the entries. In past, we had
4807 to first check what type of connection it is and then cast it to
4808 correct ID entry type. Now, we can directly cast the opaque
4809 pointer to the SilcIDListData (no matter what ID entry it actually
4810 is) and get the data needed.
4812 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4815 in some circumstances even if threre were timeout tasks, though not
4816 IO tasks, but tasks anyway. Now fixed.
4818 * Defined SilcServerConnection structure to hold connection specific
4819 stuff about directly connected servers and routers. The definition
4820 is currently in silcd/server_internal.h. I thought about having
4821 a bit more important role fro this struct but for now it is used
4822 only when connecting to other server (or router actually).
4824 * Added connecting retry support in server when connecting to
4825 router(s). The retry feature implement exponential backoff
4826 algorithm. Also, added SilcServerParams structure to hold default
4827 parameters for server. For now, it include these retry settings
4828 and are hard coded. After server is moded to be as Silc Server
4829 Library this structure will be more important.
4831 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Changed client librarys channel->clients table to SilcList and
4834 changed code accordingly.
4836 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Changed client's channel table to SilcList and changed code
4839 accordingly. Also changed SilcChannelClientEntry to include back-
4840 pointer to the channel so that client entry can use that structure
4841 as list as well and we have fast cross-reference to the channel.
4842 This change dramatically decreased the complexity of channel
4843 handling with client entry and vice versa (removed one extra
4844 loop when searching for channel entry from many functions).
4846 * Changed server->sim from table to SilcDList and changed code
4849 * NAMES command can now be used from user interface. It will show
4850 the user list on the channel, neatly.
4852 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4853 Code now saves realname of the user if it becomes available.
4855 * Renamed configure.in to configure.in.pre and made ./prepare
4856 script to automatically add correct version string to
4857 configure.in which it creates from configure.in.pre.
4859 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * NAMES command reply now shows users mode with the nickname when
4864 * Moved silc_client_ch[u]mode[_char] functions from
4865 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4866 place sucks, they are utility functions and should be in some
4869 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4871 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4874 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Added TRQ (efficient deque and list library) into lib/trq. This is
4879 a very good list library that is currently used in the SILC. Defined
4880 SilcList API over the library because I didn't like the API very
4881 much. See lib/trq/silclist.h for the API and examples of how to
4882 use the API. Fixed various places in the code to use the new
4883 SilcList API. The SilcList is meant for lists that has a structure
4884 already defined as a list. It is not suitable to add just some
4885 context to the list (in TRQ, the context is the list actually).
4887 So, I defined SilcDList that can be used for the purpose where
4888 predefined list structure does not exit. This can be used as
4889 such list. Now some context just can be added to the SilcDList.
4890 Currently this list is not used in the SILC just yet, though there
4891 are a lot places where this can replace dynamically allocated
4892 tables and I will fix these places, later, to use SilcDList.
4893 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4894 and use TRQ internally).
4896 Also fixed some annoying warning messages that the original TRQ
4897 code generated. Also minor changes to TRQ's Makefile.in.
4899 * Added support for querying by Client ID to both WHOIS and
4900 IDENTIFY commands into server, as required by the protocol.
4902 * Removed method function pointers from SilcBuffer structure. They
4903 weren't used to anything and just increased the context size for
4904 no good reason. This change also made silc_buffer_alloc and
4905 silc_buffer_free functions inline functions.
4907 * Disabled command flooding detection support until it's fixed so
4908 that it accepts commands in but does not execute them more than once
4911 * Added silc_net_localhost(), to return local hostname, into
4912 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4913 that must be initialized before calling silc_client_init.
4915 * Added new function: silc_server_send_notify_on_channels to send
4916 notify messages to all channels client has joined. It is assured
4917 that the message is sent only once per client.
4919 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4920 lib/silcutil/silcutil.[ch] as silc_format function. The new
4921 function is generic and is used by server as well, not only by
4922 the logging routines.
4924 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4925 the provided version string was not acceptable. Added new function:
4926 silc_ske_check_version into lib/silcske/silcske.h. The function
4927 must be implemented by the application (client or server) and it
4928 does not reside in the SKE library. The function checks the version
4929 string remote end sent.
4931 * Added back pointers (to opaque context and to SilcSocketConnection)
4932 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4934 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4935 duplicate packet context structure.
4937 * Changed `notify' client operation to send same arguments as client
4938 receives from server except for ID's. ID's are mapped to correct
4939 ID entry and that is returned. Also, if channel entry is not sent
4940 by server but the notify is for channel the channel entry is sent
4941 to application (otherwise application doesn't know that it is for
4942 channel (library gets it from packet's Destination ID)).
4944 * Added silc_client_remove_from_channels into client library to
4945 remove a client from all channels it has joined to. Used when
4946 received SIGNOFF notify from server. Added also new function
4947 silc_client_replace_from_channels to replace old ID entry with
4948 new ID entry on all channels. Used when received NICK_CHANGE
4951 * Fixed ID Cache list handling in silc_idlist_get_client in
4952 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4953 to get (or query) client by ID.
4955 * Updated TODO list.
4957 * Added connection authentication status message defined by the
4958 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4959 support for these into the code in client and server side.
4961 * Added generic function silc_client_send_command to send any command
4962 with variable argument list. Application should use this function
4963 to send commands if the command functions provided by the library
4964 does not suite for the application's user interface needs.
4966 * Added new `failure' client operation. Application is notified about
4967 received failure packet if client is executing a protocol. In this
4968 case the protocol's execution has failed.
4970 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4971 is required by the protocol.
4973 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4974 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4977 * Added status flag to SilcSKE object to indicate realtime status
4978 of the SKE protocol.
4980 * Application receives now exactly same command reply arguments as
4981 the library receives from server. However, if ID is received the
4982 corresponding ID entry is returned to the application (eg. Client
4983 ID is mapped to correct SilcClientEntry entry and that is returned).
4984 Changed command_reply client operation due to this change.
4986 * Changed all ID's in commands and in command replys as ID Payloads.
4987 Change affected both client and server side codes.
4989 All ID's sent in SILC network (with execption of ID's in SILC
4990 Packet header) are sent in ID Payload to support variable length
4993 * Server now notifies nick changes and notifies all clients on
4994 the channels about the new nickname (about the new Client ID,
4997 * Implemented CMODE command to change channel modes. Supports all
4998 channel modes defined by the protocol specs except ban and invite
4999 lists. (Also, private channel key mode is supported but support for
5000 setting private channel key in client is missing, thus, this mode
5001 has no effect on client side (except that server requires that the
5002 client uses private channel key and normal channel traffic does not
5005 Also, invite mode works per se, but INVITE command does not work
5006 yet correctly, so you can set channel as invite only channel but
5007 inviting clients to the channel does not work (it is yet to be
5008 thought what's the best way to do it).
5010 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5011 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5012 Implemented CUMODE command to change user's mode on the channel.
5013 Supports all modes defined by the protocol specs.
5015 * Added NAMES command reply to return users modes on the channel.
5017 * Removed unnecessary and slow ciphers from lib/silccrypt.
5019 * Set SO_KEEPALIVE option to connection sockets by default.
5021 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5023 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5024 redefined the Notify Payload into protocol specs.
5026 * Added silc_id_payload_parse_id to get ID directly from raw
5029 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5032 accept searching by Client ID as well.
5034 * Added support for LEAVE and SIGNOFF notify types in client library.
5036 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5037 to parse ID Payload from raw data.
5039 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Added flags parameter into silc_ske_assemble_security_properties
5042 function in lib/silcske/silcske.[ch].
5044 * Changed notify client operation to fit better for notify messages
5045 sent by server. The notify payload received from server is now
5046 passed to the application (after parsing it to SilcNotifyPayload).
5047 It is application's responsibility to retrieve the arguments
5048 from the payload and show the message the way it wants. The message
5049 sent by server is implementation specific.
5051 * Changed public keys to comply with the protocol specification.
5052 Old public keys are not supported anymore and are not compatible.
5054 * Removed nickname from Channel Payload as the latest draft removed
5055 it. The client must resolve the nickname from the NAMES command
5056 reply received when it joined the channel.
5058 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5060 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Fixed some errors in protocol specification drafts.
5064 * Created lib/silccore/silcnotify.c to implement Notify Payload
5065 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5066 generic payloads described by protocol specifications. The file
5067 includes implementations for ID Payload and Argument Payload.
5069 * Changed Command Payload implementation to use the new Argument
5070 Payload. Changed command_xxxx_payload to command_payload_xxxx
5071 to comply with SILC coding conventions.
5073 * Added suppport for Argument Payload handling in Notify Payload
5074 implementation as protocol requires it. Added the new support
5075 into server and client lib as well.
5077 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Added support for multiple nicknames on same channel. [n] is
5080 added locally to the nickname if there are more than one same
5081 nicknames on the channel.
5083 * Server now sends all nicknames that matched WHOIS request.
5084 Client also shows the list received from server.
5086 * Added TOPIC command to client side. User can now set and show
5087 current topic on channel.
5089 * Added MOTD command to client and server. Also, server sends the
5090 motd when client connects to the server.
5092 * Changed version strings to comply ISO 8601.
5094 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Fixed protocol error handling in client library. It should now
5097 cope even if the SKE fails for some reason.
5099 * Made new protocol specification drafts for submitting to IETF.
5101 * Implemented TOPIC command to server in silcd/command.c.
5103 * Added two new notify types into lib/silccore/silcnotify.h:
5104 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5105 notify nickname change and topic setting/change on a channel.
5107 * API change of command_reply operation in client library. The
5108 application gets now the status type received from server as well.
5110 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5114 * Cras fixed and optimized the packet handling even further and
5115 it should work now. Minor change to the prototype of function
5116 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5118 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Added new function into lib/silcutil/silcschedule.[ch]:
5121 silc_schedule_with_fd to select() a specified fd. The function
5122 returns after timeout expires or data arrives or goes. The
5123 function is used by packet routines to wait that all data is
5124 received from network.
5126 * Fixed data reading from network in lib/silccore/silcpacket.c.
5127 The code now assures that all data is read from the fd and then
5128 continues packet processing. This was a bug fix since the code
5129 used to drop some data in some circumstances.
5131 * Added new function into lib/silcclient/client.[ch]:
5132 silc_client_start_key_exchange to start key exchange after
5133 connection has been established to server. The code internally
5134 now uses this funtion but its main purpose was to provide it
5135 for applications that perform their own connecting. After
5136 application has created a connection it merely calls this
5137 function to start the key exchange between client and server.
5138 The library takes care of everything else after that.
5140 Updated also lib/silcclient/README to explain the usage of
5143 * Do not send to application information that connection has
5144 been established. Application gets notified it by connect
5147 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Applied cras's patch to add silc_schedule_one function. The
5150 function runs scheduler once and returns.
5152 * Fixed the scheduler after cras messed it up. The timeout
5153 handling works now as it's supposed to work.
5155 * Added into lib/silccore/ silcnotify.h to include notify
5156 message types support. Changed silc_server_send_notify*
5157 functions, in server.[ch], to support those new notify types.
5158 Added the support for the notify types into client library,
5159 as well. Added new notify client operation into ops.h in
5162 * Changed silc_server_packet_send_to_channel to send normal
5163 packets instead of just channel message packets. The function
5164 is now used to send the notify packets to channels. It is not
5165 used to send channel message packets anymore, as server never
5168 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5169 va_arg()s as it seems to require it nowadays. I guess, if SILC
5170 is compiled with older va_arg() the new code should work anyway.
5172 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Splitted core library. Core library (lib/silccore) includes
5175 now only SILC protocol specific core (and common) components.
5176 Created new utility library (lib/silcutil) that includes more
5177 generic purpose stuff. The stuff for util library was taken
5178 from the old core library. This was minor and easy split.
5180 * Created SILC Client Library (lib/silcclient) that includes
5181 implementation of the SILC client without user interface. This
5182 was major move from silc/ directory. The code has been changed
5183 so that it is transparent towards the user interface. The
5184 silc/ directory includes now the same user interface as before
5185 and it uses the new client library. Read lib/silcclient/README.
5186 Basicly, the client library performs everything else related
5187 to SILC except user interface handling. Also, configuration
5188 files are considered to be part of user interface and library
5189 does not handle them.
5191 This change also changed a lot of structures, function naming etc.
5192 Most important change was that SilcClientWindow object was
5193 renamed to SilcClientConnection in the client library. Created
5194 also new file lib/silcclient/ops.h. Also added new files
5195 silc/local_command.[ch] and silc/client_ops.[ch].
5197 All these changes were made to make it easier for user interface
5198 designers to create what ever user interface for the SILC client
5201 It is also expected that the server will be moved to lib
5202 directory as well and SILC Server Library will be created;
5203 sometimes in the future.
5205 * Removed Local commands from lib/silccore/silccommand.h as
5206 they are application specific and new client library does not
5207 handle any of those anymore.
5209 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5210 old client implementation in silc/.
5212 * Added support for callback functions in SILC_LOG_* macros.
5213 Application can now set its own callbacks that will be called
5214 instead of using the default functions that will always print
5215 the debug messages to stderr (or stdout). Also, debugging can
5216 now be disabled by setting silc_debug to FALSE and re-enabled by
5217 setting it to TRUE. Note, that logging will still work even
5218 if debugging is disabled.
5220 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5221 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5222 silc_log_reset_debug_callbacks.
5224 * To enable debugging in silc client one must give now -d
5225 option on command line.
5227 * Changed silc_schedule_init to automatically allocate task queues
5228 if they are not allocated before calling it.
5230 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Added GMP 3.1 into math library.
5234 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5237 a channel in SILC network. The packet is used by servers and
5238 routers to notify other routers that user has left a channel.
5239 This little feature was missing until now. Added the feature
5240 to protocol specification as well.
5242 Added functions: silc_server_send_remove_channel_user and
5243 silc_server_remove_channel_user into server.[ch].
5245 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5246 lib/silccore/silcpacket.h. However, they are not implemented
5249 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Fixed joining to a channel and sending channel messages
5252 between server and router. The channel message sending should
5253 now work inside a cell.
5255 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Fixed the private message sending between server and router.
5258 The private message sending should now work inside a cell.
5260 * Added silc_server_replace_id into server.[ch] to replace
5261 existing ID in the SILC network.
5263 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5264 and silc_idlist_replace_server_id into idlist.[ch] in server.
5266 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Fixed the server to server connections. Server can again now
5269 connect to router. Router to router connections probably does
5272 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Added dynamic protocol registering support. Now protocols can
5275 registered and unregistered on the fly. Patch by cras.
5277 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Added lib/contrib directory to hold routines that some platforms
5280 don't have but are needed by SILC.
5282 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5283 into lin/contrib to provide getopt() and getopt_long() for
5284 those who don't have it.
5286 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added AWAY command to client. When away message is set and
5289 client receives a private message packet the client automatically
5290 replies to the sender with the away message.
5292 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5293 bug seemed to be the cause of recent problems when compiling
5296 * Added version detection support to SKE protocol specification
5297 and added the new changes to the SKE implementation as well.
5298 There were other minor changes in the SKE protocol as well.
5300 Many changes in lib/silcske/silcske.[ch] and in
5301 lib/silcske/payload.[ch].
5303 * Added ^U functionality, clear input line. Patch from cras.
5305 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Mainly small bugfixes on core library. Fixed some debugging
5308 logging and buffer overflow in silclog.c.
5310 * Updated config.sub and config.guess on the distribution tree.
5312 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Added command lagging support in server. Client may execute
5315 commands now only once in two seconds.
5317 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Optimized packet reception. MAC computation and checking is now
5320 also more optimized. A lot previously duplicated code is now
5321 used as generic by both client and server.
5323 * Fixed key pair generation in clientutil.c
5325 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Added into lib/silccore/silcbufutil.[ch] new function;
5328 silc_buffer_realloc.
5330 * Moved generic packet sending/encryption functions to
5331 lib/silccore/silcpacket.[ch] from client and server. Some
5332 rewriting of the functions.
5334 * Moved all generic packet reception/decryption functions to
5335 lib/silccore/silcpacket.[ch] from client and server. The
5336 packet processing is now much cleaner in both client and server.
5337 These were major changes in both client and server.
5339 * Created many common functions in server to do packet sending.
5340 Previously code were duplicated a lot, this has been removed
5343 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Rewrote major parts of the ID cache system. Don't know
5346 whether it is better now or not but at least the API is more
5349 * Major rewrite on ID cache stuff on client because of the ID
5350 cache API changes. Added idlist.c to client.
5352 * Also major rewrite on ID cache stuff on server as well.
5353 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5354 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5355 in hand, instead they are all put into the ID cache system now.
5356 All server_idlist_* routines uses ID cache now instead of
5357 traversing its own lists (those lists does not exist anymore).
5358 SilcIDList though still exists. Also, SilcXXXEntry's are
5361 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Finally made the SKE implementation compliant to the protocol
5364 specification. All mp integers are now binary encoded as
5365 opposed being HEX encoded.
5367 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5370 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5371 functions: silc_[encode/decode]_pem. Also added function
5372 silc_encode_pem_file to PEM encode with newlines ('\n') for
5375 * SILC public keys are now encoded either PEM or binary. Same
5376 option is for private keys as well. By default private keys
5377 are binary encoded and public keys PEM encoded. Silly HEX
5378 encoding were removed.
5380 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5381 function to create fingerprints.
5383 * Fixed a bug in SHA1; does not change the original data anymore.
5385 * Partly implemented INFO command on client and server side.
5386 Fixed CLEAR command. Changes to SERVER command; show current
5387 server(s) when giving command without arguments. Added
5388 VERSION command to client.
5390 * Added check to server that unregistered connections cannot
5391 execute commands (unless it is specificly allowed).
5393 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Fixed screen refresh.
5397 * Fixed channel joining bug from client. On some circumstances
5398 client tried to join to a channel it had already joined.
5400 * Added public key verification process into client's protocol.c.
5401 The client now verifies the public key from user and saves
5402 it into ~./silc/serverkeys/ directory.
5404 Added into: clientutil.[ch]: silc_client_verify_server_key.
5406 * Changed SKE protocol's silc_ske_initiator_finish function
5407 to accept callback function that verifies the received public
5408 key. Removed old silc_ske_verify_public_key function.
5410 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5413 silc_pkcs_private_key[_data]_set.
5415 * Made the password and public authentication more cleaner in
5416 server's protocol.c.
5418 * Removed historic and obsolete protocol `channel_auth' from
5419 both client and server.
5421 * Removed wrong way of sending command status messages from
5422 server to client in server's command.c. The old way violated
5423 protocol specification.
5425 Changes to silccore/silccommand.[ch]: removed
5426 silc_command_encode_status_payload -> not needed anymore,
5427 changed silc_command_encode_payload_va to accept extra
5428 argument on variable argument list. The argument type must
5429 now be provided to the function. Also, added new function:
5430 silc_command_encode_reply_payload_va which is same as
5431 normal command_encode_payload_va except command status type
5432 is provided as extra argument.
5434 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
