1 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the SILC packet header to have the first two bytes
4 (the packet length) encrypted. Affected files aroung the
5 code tree, lib/silccore/silcpacket.[ch]. Removed the
6 SilcPacketCheckDecrypt callback. It is not needed anymore
7 since the silc_packet_receive_process will determine now
8 whether the packet is normal or special.
10 * Implemented the unidirectional MAC keys. Affected files
11 lib/silcske/silcske.c, silcd/protocol.c and
12 lib/silcclient/protocol.c.
14 * Implemented the packet sequence number to the MAC computation.
15 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
16 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
17 lib/silcclient/protocol.c.
19 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Allow backup router to announce servers. All servers
22 announced by backup router are added to the global list
23 automatically. Update hte server's socket to our primary
24 router also when backup router announces a server.
25 Affected file silcd/packet_receive.c.
27 * Do not update the client->router in the function
28 silc_server_udpate_clients_by_server if the client is on
29 global list. We might fail to find any specific server
30 for locally connected clients and local cell clients. They
31 should still use the `from' and not `to' as client->router.
32 This fixes backup router resuming protocol. Affected file
35 * Decrease channel statistics count only if the channel
36 deletion worked. Affected files are silcd/server.c and
39 * Added silc_server_update_servers_by_server to update origin
40 of all server entries. Used during backup router protocol.
41 Affected files silcd/server_util.[ch], silcd/server.c. and
42 silcd/backup_router.c.
44 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
45 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
46 silc_hmac_get_hash and silc_hmac_get_name. Affected file
47 lib/silccrypt/silchmac.c.
49 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Assure that router cannot reroute the same channel message
52 to the sender. Affected file silcd/packet_receive.c.
54 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Made better checks that the channel message is not sent
57 to the router it came from. Affected file is
58 silcd/packet_send.c. Fixed memory leak too.
60 * Announce informations for incoming router connection, but
61 only after checking if it is replaced by backup router.
62 Affected file silcd/packet_receive.c.
64 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
66 * Fixed the backup resuming protocol to work in multiple
67 router environment. Affected file silcd/server_backup.c.
69 * Route packet only to one router in the function
70 silc_server_packet_send_to_channel. Affected file is
73 * Fixed silc_server_send_notify_dest to set the broadcast
74 flag. Fixed the silc_server_send_notify_topic to actually
75 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
76 Affected file silcd/packet_send.c.
78 * Changed the SFTP Filesystem interface. Changed the
79 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
80 the filesystem operation function. The SilcSFTPFilesystem
81 is now a context that is allocated by all filesystem allocation
82 functions and it already includes the operations structure
83 and filesystem specific context. It is given as argument
84 now to the silc_sftp_server_start. This made the interface
85 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
86 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
88 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Changed the backup router adding and getting interfaces
91 in the server. The router that will be replaced by the
92 specified backup router is now sent as argument. Affected
93 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
96 * Added silc_net_addr2bin_ne to return the binary form of
97 the IP address in network byte order. Affected files
98 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
100 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Check for existing server ID in silc_server_new_server
103 and in silc_server_connect_to_router_final and remove the
104 old entry if it exists. Affected file silcd/packet_receive.c,
107 * Send the channel message always to only one router, either
108 in upstream or downstream. Affected file is
111 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
113 * Wrote the definition of the backup resuming protocol to the
114 protocol specification.
116 * Removed one redundant channel key generation from normal
117 server during joining procedure. Removed one redundant
118 channel key sending from server to router during joining
119 procedure. Affected file silcd/command.c.
121 * Made minor bugfixes to the backup router resuming protocol.
122 Affected file silcd/server_backup.c, server.c.
124 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Added --disable-asm configuration option. Affected files
127 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
130 * Implemented the backup resuming protocol that is used to
131 resume the primary router position in the cell after the
132 primary router comes back online. Affected files
133 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
134 and silcd/server_util.[ch].
136 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
138 * Sleep two (2) seconds after sending QUIT command to server.
139 Affected file lib/silcclient/command.c.
141 * Assure that if outgoing data buffer is pending do not force
142 send any data. Affected file silcd/packet_send.c.
144 * Assure that if outgoing data buffer is pending do not force
145 send any data. Affected file lib/silcclient/client.c.
147 * Implemented the backup router support when the primary router
148 goes down. The servers and routers can now use the backup
149 router as new primary router without loosing connectivity.
151 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
153 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
154 in the server to indicate disabled entry. All data read
155 from the connection will be ignored and no data is sent
156 for entry that is disabled. Affected files are
157 silcd/idlist.h, silcd/server.c.
159 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
161 * Created SFTP client and server test programs in the
162 lib/silcsftp/tests directory.
164 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
166 * Implemented memory filesystem (virtual filesystem) for
167 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
170 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
172 * Implemented the SFTP (SSH File Transfer Protocol) to the
173 lib/silcsftp. It includes SFTP client and SFTP server
176 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Moved lib/silccore/silcprotocol.[ch] to the
179 lib/silcutil library.
181 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
182 take variable argument list pointer as argument. Affected
183 file lib/silcutil/silcbuffmt.[ch].
185 * Added silc_buffer_set function that is used to set data
186 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
187 Affected file lib/silcutil/silcbuffer.h.
189 * Changed various routines in the core library to use the new
190 silc_buffer_set instead of allocating new buffer only for
193 * Added 64-bit value formatting and unformatting support to the
194 silc_buffer_[un]format routines. Affected file is
195 lib/silcutil/silcbuffmt.[ch].
197 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
198 to includes/bitmove.h.
200 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
202 * Fixed channel user mode saving in client library. Affected
203 file lib/silcclient/command[_reply].c.
205 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
207 * Defined the file transfer to the SILC Protocol. Added
208 new packet type SILC_PACKET_FTP and defined File Transfer
209 Payload. The mandatory file transfer protocol is SFTP
210 (SSH File Transfer Protocol). Affected file in addition
211 of the internet draft is lib/silccore/silcpacket.h.
213 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
214 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
215 is used as part of backup router protocol when the primary
216 router of the cell is back online and wishes to resume
217 the position as primary router.
219 * Redefined the MAC generation keys in the protocol. The
220 same key is not used anymore in both direction. Both
221 direction will now use different keys for sending and
222 receiving. This fixes a potential security flaw. This
223 change causes incompatibilities in the protocol.
225 * Redefined also the MAC computation from the packet.
226 An packet sequence number is now added to the MAC
227 computation. This prevents possible replay attacks against
228 the protocol. This change too causes incompatibilities
231 Added `sequence' field to the SilcPacketContext to hold
232 the current sequence number for the packet.
234 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
236 * Added `created' field to the SilcIDListData in the file
237 silcd/idlist.h to indicate the time when the entry was
240 * Added `created' field to the SilcChannelEntry too. Affected
243 * Added `creation_time' aguments to all the announcement functions
244 in the server. If it is provided then only the entries that
245 was created after the provided time frame are actually
246 announced. Affected file silcd/server.[ch].
248 * The protocol says that the Channel ID's IP address must be
249 based on the router's IP address. Added check for this in
250 the silc_server_new_channel when processing incoming New Channel
251 Payload. Affected file silcd/packet_receive.c.
253 * Print out the correct version with --version in SILC client.
254 Affected file irssi/src/silc/core/silc-core.c.
256 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
258 * Fixed WHOWAS command to check for completnes of the client
259 entry always, not just when the command is coming from client.
260 Affected file silcd/command.c.
262 * Added new function silc_server_packet_queue_purge to purge the
263 outgoing data queue to the network. After the function returns
264 it is guaranteed that the outgoing packet queue is empty.
265 Affected file silcd/packet_send.[ch].
267 * Purge the outgoing packet queue in the rekey protocol's final
268 callback to assure that all rekey packets go to the network
269 before quitting the protocol. Affected file silcd/server.c.
271 * Added silc_client_packet_queue_parse as similar function as
272 in server to the client library. The affected file is
273 lib/silcclient/client.c.
275 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Splitted silcd/server.c and created silcd/server_util.[ch]
278 for utility functions.
280 * Added new socket flag SILC_SF_DISABLED to indicate that the
281 connection is open but nothing can be sent to or received from
282 the connection. Affected file lib/silcutil/silsockconn.[ch].
283 The checking for disabled socket is checked in the low level
284 silc_socket_write and silc_socket_read functions.
286 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
288 * Allow only nicknames and channel names that fits into the
289 7-bit unsigned char ASCII set. Affected file silcd/command.c.
291 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
293 * When processing JOIN command reply in server check that if
294 the channel exists in our global list we'll move it the local
295 list. Affected file silcd/command_reply.c.
297 * Fixed the check whether client is joined on the channel already
298 in JOIN command. Affected file lib/silcclient/command.c.
300 * Fixed the JOIN command reply to check whether the channel
301 already exists. Affected file lib/silcclient/command_reply.c.
303 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Added silc_ske_status_string to map the SKE error numbers
306 to readable strings. The affected files are
307 lib/silcske/silcske[_status].[ch].
309 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
311 * Do not show the private channels on the WHOIS channel list
312 as it is not allowed by the protocol. The affected file is
315 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
317 * Assure that the packet length digged from the actual packet
318 is something sensible in the silc_packet_decrypt_rest_special
319 in lib/silccrypt/silcpacket.c.
321 * Free and NULL the allocated pointer in silc_hmac_alloc if
322 the HMAC allocation fails. The affected file is
323 lib/silccrypt/silchmac.c.
325 * Print the selected security properties to the log files in
326 the server. Affected file silcd/protocol.c.
328 * Add SKE's reference counter even if calling the completion
329 callback manually. Otherwise it goes negative, although it
330 does not cause any problems. The affected file is
331 lib/silcske/silcske.c.
333 * Remove the client entry with short timeout after giving the
334 KILL command. Affected file lib/silcclient/command.c.
336 * Fixed to send error reply in WHOIS and IDENTIFY commands in
337 case all found clients are already disconnected (WHOWAS would
338 found them) in the server. Affected file silcd/command.c.
340 * Update the last_receive (time of last data received) to be
341 updated only when received private or channel message so that
342 the idle time showed in WHOIS makes more sense.
344 * Added boolean field `valid' in to the SilcClientEntry in the
345 client library to indicate whether the entry is valid or not.
346 This fixes the nickname change bug on channel when changing
347 the nickname to be same than the old (like nick to Nick) the
348 nickname formatter doesn't set the new nick anymore to Nick@host.
349 Affected file lib/silcclient/idlist.[ch].
351 * Now actually fixed the nickname changing on disconnection.
352 Added new function silc_change_nick to the Irssi SILC Client.
353 Affected file irssi/src/silc/core/client_ops.c,
354 irssi/src/silc/core/silc-nicklist.[ch].
356 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Check that the public key exists in the GETKEY command before
359 trying to encode it. Affected file silcd/command.c.
361 * Print some notifications on received public keys with GETKEY
362 command in the Irssi SILC Client. Affected files are
363 irssi/src/fe-common/silc/module-formats.[ch],
364 irssi/src/silc/core/client_ops.c.
366 * Use IDENTIFY command to resolve the server information in the
367 GETKEY command instead of INFO command. Affected file
368 lib/silcclient/command.c.
370 * All command reply functions in the client library now calls
371 the pending command reply callbacks even if an error has
372 occurred. The server has done this a long time and now it was
373 time to move the client library to this as well. Now all
374 errors can be delivered back to the pending command reply
375 callbacks if necessary. Affected files are
376 lib/silcclient/command[_reply].[ch].
378 * Change the nickname on disconnection back to the username
379 because in reconnect the server will enforce it to it anyway.
380 Affected file irssi/src/silc/core/silc-servers.c.
382 * Fixed a config file parsing bug in the Irssi SILC client.
383 Affected file irssi/src/silc/core/clientconfig.c.
385 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
387 * When printing the channel mode on JOIN, verify that the
388 channel key and channel's HMAC are valid. Affected file
389 irssi/src/silc/core/client_ops.c.
391 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
394 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
395 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
397 * Removed channel key rekey task deleting from the function
398 silc_server_save_channel_key. Affected file silcd/server.c.
399 Added explicit timeout task context instead that is used to
400 delete the task if we are registering a new task before the
401 new task has elapsed.
403 * When channel key rekey occurs the client library now saves
404 the old channel key for a short period of time (10 seconds) and
405 is able to use it in case some is still sending channel
406 messages encrypted with the old key after the rekey. Affected
407 file lib/silcclient/[idlist.h|client_channel.c].
409 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
411 * Added check to the silc_server_new_id_real to not accept
412 new ID if it is the sender's own ID. Affected file is
413 silcd/packet_receive.c.
415 * Assure that we do not announce ourself or the one we've
416 sending our announcements when we're router and are announcing
417 servers to our primary router. Affected file silcd/server.c.
419 * Fixed silc_server_command_identify_check_client to assemble
420 correct WHOIS packet. It send corrupted WHOIS packet and
421 caused problem with router to router connections. Affected
422 file silcd/command.c.
424 Fixed also silc_server_command_whois_check the same way
425 as for the IDENTIFY command.
427 * Added new SilcIDListStatus to the server in the SilcIDListData
428 structure. The status now includes the current status of
429 the entry (like registered, resolved etc.). Affected file
430 silcd/idlist.[ch]. Defined a bunch of different status types
431 as well. This replaced the old boolean registered field as well.
433 Added resolve_cmd_ident field to the SilcClientEntry structure
434 too so that if the entry is for example being resolved so
435 another command may attach to the same pending command reply
436 without requiring to resolve the same entry again. This concept
437 should optimize the WHOIS and the IDENTIFY resolving under
438 heavy load by taking away unnecessary resolving for entries
439 that are being resolved already.
441 Added support for adding multiple pending commands for one
442 command idenfier. Affected file silcd/command[_reply].[ch].
444 * Fixed WHOIS and IDENTIFY save to remove the cache entry
445 before deleting the data. Otherwise the hash table will have
446 freed data in comparison functions. Affected file is
447 silcd/command_reply.c.
449 * Fixed silc_idlist_replace_client_id to add the new entry to
450 the cache with NULL nickname. Otherwise there will be invalid
451 memory as the nickname after the nickname is freed. Affected
452 file silcd/packet_receive.c.
454 * Fixed the silc_idlist_get_clients_by_hash. The entries was
455 saved into wrong slots because the previous number of entries
456 was not taken into account. Affected file silcd/idlist.c.
457 Fixed same thing in silc_idlist_get_clients_by_nickname too.
459 * If we are router and we receive JOIN notify to a channel that
460 does not have any users then notified client is marked as the
461 channel founder, as it is it. The affected file is
462 silcd/packet_receive.c
464 * Added to the extended hash table API's table_del_*ext functions
465 the destructor as argument too, so that the caller can decide
466 which destructor to use or whether to use destructor at all.
467 Affected file lib/silcutil/silchashtable.[ch].
469 * Fixed ID Cache purging. It actually deleted the entries from
470 the hash table after the data was freed. The hash table ended
471 up comparing freed memory. The affected file is
472 lib/silccore/silcidcache.c.
474 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Fixed Irssi SILC client's KILL command's HELP syntax.
478 * The USERS command now resolves the detailed user information
479 if the userinfo field is missing. Affected file is
480 lib/silcclient/command_reply.c.
482 * Do not print error in silc_file_read if the read file does
483 not exist. Just silently return NULL. Affected file is
484 lib/silcutil/silcutil.c.
486 * Fixed the silc_log_output to not wine about NULL filename
487 and to not create some bogus " " filename. Affected file is
488 lib/silcutil/silclog.c.
490 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
492 * Fixed various printing bugs on the user interface in the
493 Irssi SILC Client. Minor changes that were forgotten from
496 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
498 * Fixed the configure.in.pre and the compilation and distribution
499 environment to support the new autoconf 2.52. That version is
500 now required to compile the CVS trunk.
502 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
504 * Renamed function silc_parse_nickname to silc_parse_userfqdn
505 to generally parse user@fqdn format strings. Affected file
506 lib/silcutil/silcutil.c.
508 * Added nickname_format and nickname_force_format fields to the
509 SilcClientParams structure. The first one defines the format
510 for the nicknames that the library will enforce if the receives
511 multiple same nicknames. The second one is boolean value and
512 can be used to force the library to always enforce the format
513 to the nicknames regardles whether there are multiple nicknames
514 or not. This configurable formatting was employed to flexibly
515 support accessing multiple nicknames from the user interface.
516 The userinterface can now set the nicknames to what ever format
517 they prefer. Affected file lib/silcclient/silcapi.h.
519 Added function silc_client_nickname_format to the file
520 lib/silcclient/idlist.c. It performs the nickname formatting.
522 Added new field `hostname´ to the SilcClientEntry context.
523 It holds the hostname of the client. Affected file is
524 lib/silcclient/idlist.h.
526 * Irssi SILC Client sets the nicknames in nick@hostn format.
527 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
528 irssi/src/silc/core/silc-core.c.
530 The WHOIS printing now also shows both the real nickname and
531 the formatted nickname so that user knows how to access the
532 user if there are multiple same nicknames cached. Affected
533 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
534 printing formatting too to take the hostname now as a separate
535 argument. The Affected file is
536 irssi/src/fe-common/silc/modules-formats.[ch].
538 * Changed the silc_client_get_clients_local to accept the formatted
539 nickname as argument. It accepts the real nickname too but the
540 formatted nickname can be used to find the true entry from
541 multiple entries. Affected file lib/silcclient/silcapi.h and
542 lib/silcclient/idlist.c.
544 * Added nickname_format_parse field to the SilcClientParams.
545 It is a callback function provided by the application to parse
546 the nickname out of the formatted nickname string. The library
547 calls it to get the nickname from the formatted string. Since
548 the application generally knows better the format of the nickname
549 string it parses it instead of the library, even though library
550 encodes the formatted string. If the callback function is not
551 provided then the library will use the string as is. The
552 affected file is lib/silcclient/silcapi.h.
554 * All the nickname strings passed to the client library in
555 commands are now expected to be formatted nickname strings.
556 If the command does not support the formatted nickname string
557 it will assume that the sent string is the actual nickname.
558 Affected file lib/silcclient/command.c.
560 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
562 * Added public key authentication support to OPER and SILCOPER
563 commands in the client library. Affected file is
564 lib/silcclient/command.c.
566 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Changed the get_auth_methdod client operation to be asynchronous.
569 It can be async if the application resolves the authentication
570 method from the server during the negotiation. Added new
571 SilcGetAuthMeth completion callback that the application will
572 call after resolving the authentication method.
574 Added function silc_client_request_authentication_method that
575 the application can use to resolve the authentication method
576 from the server. Added also SilcConnectionAuthRequest callback
577 that the library will call after the server has replied. The
578 application can call this function if it does not know the
579 current authentication method.
581 Affected files are lib/silcclient/client.c and
582 lib/silcclient/silcapi.h.
584 * The Irssi SILC client now automatically resolves the authentication
585 method incase any configuration information is not present (and
586 currently there never is). The affected file is
587 irssi/src/silc/core/client_ops.c.
589 * Fixed public key authentication from the client library.
590 Affected file lib/silcclient/protocol.c. Changed also the
591 protocol specification about the public key authentication in
592 the connection authentication protocol. The actual data to be
593 signed is now computed with a hash function before signing.
595 * Fixed the public key authentication from the server as well.
596 Affected file silcd/protocol.c.
598 * Removed the mlock()'s from the memory allocation routines.
599 Affected file lib/silcutil/silcmemory.c. The ./configure does
600 not check anymore for the mlock(). Affected file is
603 * Fixed USERS command in server to allow the execution of the
604 command for private and secret channels if the client sending
605 the command is on the channel. Affected file silcd/command.c.
607 * Fixed silc_client_get_clients_local to return the clients
608 count correctly. It could return wrong value. Affected file
609 lib/silcclient/idlist.c.
611 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
613 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
614 types. The assembler optimizations seemed not to like 64-bit
615 data types. The assmebler optimizations thus are now enabled
616 also for BSD systems as opposed to only enable them for Linux.
618 * Do not check for threads at all on BSD systems. Affected
619 file configure.in.pre.
621 * Removed -n and -h options from the Irssi SILC Client since
622 they are not used in silc.
624 * Fixed the prime generation to assure that the first digit
625 of the generated random number is not zero since our conversion
626 routines does not like number strings that starts with zero
627 digit. If zero digit is seen the random number is regenerated.
628 This caused some corrupted RSA keys when the zero first digit
629 was met. Affected file lib/silcmath/silcprimegen.c.
631 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed WIN32 configuration in the ./configure script.
634 Fixed to include xti.h on environments that has it.
635 Patches by Carsten Ilchmann and andrew.
637 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
639 * Changed the silc_id_create_client_id to be collision
640 resistant. It is now assured that there cannot be created
641 two same client ID's. I suspect that some weird bugs in
642 the server were actually caused by duplicate Client IDs.
643 Affected file silcd/serverid.[ch]. A router receiving
644 new ID now also assures and informs the sending server
645 if the ID caused collision.
647 * Changed the silc_id_create_channel_id to also assure that
648 there are no collisions.
650 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
652 * Statement about ignoring the Mutual Authentication flag when
653 performing rekey with PFS was a bit misleading. It is ignored
654 if it was set in the initial negotiation, it cannot be even
655 set in the rekey. Fixed in the ke-auth draft. Started the
656 new versions of the protocol drafts in the doc/.
658 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Fixed a bug in silc_client_command_identify_save when saving
661 new channel information. The channel name was no duplicated
662 and caused crash on exit. Affected file is
663 lib/silcclient/command_reply.c.
665 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Fixed the getkey command handling in the server. Send just
668 empty OK reply to the sender if the key could not be fetched
669 (but everything else was ok, like the key just was not available).
670 Changed the public key parameter to optional in the protocol
671 specs so that empty OK reply can be sent. Affected file
674 Added a message to Irssi SILC client to tell to user if the
675 server did not return a public key.
677 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Fixed a channel key regeneration bug. It registered new
680 timeout tasks exponentially until all system resources were
681 used. Affected file silcd/server.c.
683 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
685 * Added the SILC Document generator to the scripts/silcdoc.
686 It can be used to generate the Toolkit Reference Manual out
687 of the source tree. Internally it will also use the RoboDoc
688 generator now imported in util/robodoc.
690 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Added couple of return's in rekey protocol if error orccurred
693 during the protocol. The execution must be terminated.
694 Affected file silcd/protocol.c. Also, terminate the protocol
697 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
699 * The client's Client ID was created initally from the wrong
700 nickname (it could have been in format nick@host) in the
701 silc_server_new_client. Affected file silcd/packet_receive.c
703 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
705 * Added some SILC_LOG_ERROR's to various error conditions
706 if client could not be added to ID cache. Affected files
707 silcd/packet_receive.c and silcd/server.c.
709 * When client's sock->user_data is freed, NULL also the
710 client->router and client->connection pointers. Added check
711 for these pointers being NULL to various places around the
712 code. Affected file silcd/server.c.
714 * Added client->data.registered == TRUE checks to various
715 places around the code to assure that unregistered client's
716 are not handled when it is not allowed. Affected file
719 * Added `bool registered' fields to all
720 silc_idlist_[server|client]_get_* routines to indicate whether
721 the fetched client needs to be registered or not. Affected
722 file silcd/idlist.[ch].
724 * Add your own entry as registered to the ID cache in the
725 server. Affected file server.c.
727 * Fixed a bug in silc_server_new_server. The SilcServer was
728 set as the new server's context instead of SilcServerEntry.
729 This naturally caused some weird bugs.
731 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
733 * Do not delete the channel rekey task when adding it
734 for in silc_server_create_channel_key.
736 * Changed the silc_server_create_channel_key to return
737 TRUE or FALSE to indicate the success of the channel key
740 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
742 * Fixed MSVC++ project files and added missing files to
743 Makefiles under win32/.
745 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
747 * Do not add TCP_NODELAY flag if the operating system
748 does not have it defined. Affected files are
749 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
751 * Fixed buffer overflow from Irssi SILC Client. Affected
752 file irssi/src/fe-common/core/themes.c.
754 * Fixed double free in client library in the file
755 lib/silcclient/client.c when disconnecting from server.
757 * Applied double free patch from cras to Irssi SILC client.
758 Affected files irssi/src/core/[modules/expandos].c
760 * Fixed the disconnection handling to Irssi SILC Client.
761 The application must call silc_client_close_connection
762 in ops->connect client operation in case of failure of
763 the connection. Affected file is
764 irssi/src/silc/core/client_ops.c.
766 * Do not set sock->protocol to NULL in the function
767 silc_client_close_connection after executing the protocol's
768 final callback since the sock might not be valid anymore.
769 Affected file lib/silcclient/client.c.
771 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
773 * Do not enable SILC_THREADS if the linking with libpthread
774 did not happen. Affected file configure.in.pre.
776 * Added notion to protocol specification that server must
777 verify the sent authentication payload with CMODE when
778 setting the channel founder key. Implemented it to the
779 server. Affected file silcd/command.c.
781 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Added _EXTRA_DIST SILC distribution variable to the
784 distributions file. It is used to conditionally add extra
785 files or directories to the specific distribution. Affected
786 files ./prepare, Makefile.am.pre and distributions.
788 Removed the `_' from the start of the distribution names.
791 * Added README.WIN32 for instructions to compile the Toolkit
794 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Fixed a double free in disconnection in the server. Affected
797 file is silcd/server.c.
799 * Fixed the lib/silcske/groups.c to work now also with GMP
800 MP library. The string conversion did not work when using
801 specific base and the base is indicated in the string as well.
803 * Created win32/ directory which now includes MSVC++ specific
804 stuff so that toolkit (DLLs) may be compiled with MSVC++.
805 It will appear only in the toolkit distribution
807 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Changed the key material distribution function in case when
810 the hash output is too short. The data is now concatenated
811 a bit differently than it used to. Made the change to the
812 SKE protocol specification.
814 * Added better GMP detection to configure.in.pre. A patch
817 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Fixed a minor bug in SKE that might cause some problem on
820 some platforms. Affected file lib/silcske/silcske.c.
822 * Added the cookie checking for initiator in the SKE. It checks
823 that the responder returns the sent cookie unmodified. The
824 affected file is lib/silcske/silcske.c. Added new SKE
825 error type INVALID_COOKIE that can be sent during the
826 negotiation. Fixed some memory leaks as well.
828 * Added the "invalid cookie" error message to Irssi SILC client's
831 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
833 * Added `task_max' field to the SilcClientParams to indicate
834 the maximum tasks the scheduler can handle. If set to zero,
835 default values are used. Affected file lib/silcclient/silcapi.h.
837 * Fixed memory leaks in silc_client_close_connection. Affected
838 file lib/silcclient/client.c.
840 * Added silc_client_del_client_entry to client library to free
841 all memory of given client entry. Affected file is
842 lib/silcclient/idlist.[ch].
844 * Added new functions silc_client_del_channel and
845 silc_client_del_server to delete channel and server entries.
846 Affected file lib/silcclient/[silcapi.h/idlist.c].
848 * Removed silc_client_del_client_by_id from silcapi.h.
850 * Fixed the INFO command to return the server's own info
851 correctly when querying by Server ID. Affected file is
854 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
856 * Removed the non-blocking settings in WIN32 code in the
857 silc_sock_[read/write] and added SleepEx instead. Affected
858 file lib/silcutil/win32/silcwin32sockconn.c. The availability
859 of input data is now checked with FIONREAD and ioctlsocket.
861 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
863 * Call silc_schedule_task_del_by_context in the
864 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
865 Affected file lib/silccore/silcprotocol.c.
867 * Call silc_protocol_cancel for active protocols in the
868 silc_server_close_connection if the funtion
869 silc_server_free_sock_user_data has not been called.
870 Affected file silcd/server.c.
872 * Generic tasks cannot be deleted using the del_by_fd
873 task deleting function since generic tasks does not match
874 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
876 * Added a notion to SILCOPER help file that the SILCOPER works
877 only on router server, not on normal server.
879 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
881 * Added for WIN32 support for the new scheduler as well.
882 Affected file lib/silcutil/win32/silcwin32schedule.c.
884 * Fixed the SHA1 implementation to work on various platforms.
886 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
889 API. It is part of the scheduler now. Everything else is
890 as previously but some functions has changed their names.
891 Checkout the lib/silcutil/silcschedule.h for the interface.
892 Updated all applications to use the new interface. Affected
893 files are lib/silcutil/silcschedule.[ch].
895 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Found a bug in the SKE implementation. The HASH value,
898 specified by the protocol, was not computed correctly. The
899 public key of the responder was not added to the computation
900 even though it is mandatory. Affected file lib/silcske/silcske.c.
901 This unfortunately causes incompatibilities with older
904 * Added WIN32 specific network init and uninit functions:
905 silc_net_win32_init and silc_net_win32_uninit to init and uninit
906 the Winsock2. Affected file lib/silcutil/silcnet.h and
907 lib/silcutil/win32/silcwin32net.c.
909 * Set the socket always to nonblocking mode on WIN32 after
910 reading data or writing data. Affected file is
911 lib/silcutil/win32/silcwin32sockconn.c.
913 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
915 * Fixed various compilation problems under WIN32. Affected
916 files lib/silcutil/win32/silcwin32thread.c and
917 lib/silcutil/win32/silcwin32schedule.c.
919 * Removed all _internal.h #includes from public header
920 files. Internal headers must never be included from
923 Removed also the lib/silcske/payload_internal.h file.
925 * All include files that may be needed (public and some others
926 included by the public headers) by application developers are
927 now copied to the ./includes directory. It does not copy any
928 internal headers. Affected file Makefile.defines.pre and all
929 Makefile.am's under lib/ and subdirs.
931 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
933 * Do not change the ~/.silc directory's permissions automatically.
934 Affected file irssi/src/silc/core/clientutil.c.
936 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Do not cancel the protocol in silc_server_close_connection
939 it might cause recursion. Now cancelled in the function
940 silc_server_free_sock_user_data. Affected file silcd/server.c.
942 * Fixed the silc_server_remove_clients_by_server to regenerate
943 the channel keys correctly finally. Added also new function
944 silc_server_remove_clients_channels to actually do it.
945 Affected file silcd/server.c.
947 * Fixed the silc_server_new_channel to not crash by giving
948 wrong router to the new channel. Affected file is
949 silcd/packet_receive.c.
951 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
953 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
954 which is given as argument to the silc_client_alloc now.
955 It can be used to configure the client and set various parameters
956 that affect the function of the client.
958 * The USERS command in server did not check whether the channel
959 is private or secret. Affected file silcd/command.c.
961 * Added new argument to the USERS command in protocol specification.
962 The USERS command now can take the channel name as argument
963 as well. Added support for this in client and server and
964 updated the protocol specs.
966 * Completed the GETKEY command in client. It can be now used
967 to fetch also servers public key not only some clients.
968 Affected files lib/silcclient/command[_reply].c.
970 * Added silc_client_get_server to return server entry by the
971 server name. Affected files lib/silcclient/silcapi.h and
974 * Redefined the IDENTIFY command in protocol specification to be
975 more generic. It now can be used to query information about
976 any entity in the SILC Network, including clients, servers and
977 channels. The query may be based either the entity's name
978 or the ID. Added support for this in both client and server.
980 Affected files silcd/command.c and lib/silcclient/command.c
983 * Optimized the WHOIS and WHOWAS commands in the server. Removed
984 the _from_client and _from_server functions. Affected file
987 * Added silc_client_get_channel_by_id_resolve to the file
988 lib/silcclient/silcapi.h to resolve channel information by
989 its ID. Added also silc_client_get_channel_by_id that
990 does not resolve it from the server.
992 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Added SilcServerEntry context into the client library
995 to represent one server. The INFO command now allocates
996 these to save the resolved server info. For now on the
997 client library will also keep information about servers,
998 connected and resolved with INFO.
1000 The INFO command now allocates the SilcServerEntry context
1001 and saves the server info there. The COMMAND_REPLY in
1002 the INFO now returns the parameters to application in
1003 same order as defined in the protocol specification.
1005 The entries are cached in the client->server_cache.
1007 * The INFO command is now issued after received the Client ID
1008 from the server. Affected file lib/silcclient/client.c.
1010 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1011 to the application as the mode changer might be server.
1012 It is guaranteed that NULL is not returned anymore to the
1013 application. Affected file lib/silcclient/client_notify.c.
1015 The ID Type is now also passed to the application so that
1016 it can check whether the returned entry is SilcClientEntry
1019 Added new function silc_client_get_server_by_id to return
1020 the server entry by ID. Affected files are the
1021 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1023 * Do not create the channel in the Irssi SILC Client when issuing
1024 the JOIN command but when received the sucessful JOIN command
1025 reply. Otherwise the channel might get created even though we
1026 could not join it. The Affected file is
1027 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1029 * Fixed a channel joining bug in router. The router must also
1030 check the channel modes, invite and ban lists etc. when serving
1031 the JOIN command sent by normal server. Affected file is
1032 silcd/command.c. The router now resolves the client's
1033 information from the server who sent the JOIN command if it
1034 does not know it, and processes the JOIN command only after
1037 * Changed the SilcCommandCb to take new argument; void *context2.
1038 Affected file lib/silccore/silccommand.h
1040 The second argument in the command callbacks in the server now
1041 includes the SilcServerCommandReplyContext if the command was
1042 called as pending command callback from the command reply.
1043 Otherwise it is NULL. When called as pending the status of the
1044 command reply will be checked and if it was erronous the
1045 error will be sent to the original sender of the command.
1046 This way the client always receives the error messages even
1047 though the server was actually the one who received the error
1048 when it resent the command to router, for example. Affected
1049 files silcd/command[_reply].[ch].
1051 * Fixed sending WHOWAS command's error message to client if
1052 the requested client could not be found. It was missing.
1055 * Changed the CMODE and CUMODE commands reply arguments in the
1056 protocol specification. The Channel ID is now sent in both
1057 of the commands to identify the channel. Implemented this
1058 new feature to the client and server. Affected files
1059 lib/silcclient/command_reply.c and silcd/command.c.
1061 * Made better checks for invite and ban lists in the JOIN
1062 command in server. Affected file silcd/command.c.
1064 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * The server now performs the incoming host IP/DNS lookup
1067 using the silc_socket_host_lookup and thus does not block
1068 the server anymore. Affected file silcd/server.c.
1070 * Completed the multi-thread support for SILC Scheduler in
1071 the lib/silcutil/silcschedule.c.
1073 * Fixed the configure.in.pre to detect the pthread correctly
1076 * Fixed a deadlock in silc_task_queue_wakeup in the file
1077 lib/silcutil/silctask.c.
1079 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Added new function silc_schedule_wakeup that is used in
1082 multi-threaded environment to wakeup the main thread's
1083 schduler. It needs to be used when a thread adds a new task
1084 or removes a task from task queues. After waking up, the
1085 scheduler will detect the task queue changes. If threads
1086 support is not compiled in this function has no effect.
1087 Implemented the wakeup mechanism to both Unix and WIN32
1088 systems. Affected files are lib/silcutil/silcschedule.[ch],
1089 lib/silcutil/unix/silcunixschedule.c and the
1090 lib/silcutil/win32/silcwin32schedule.c.
1092 * Added new function silc_task_queue_wakeup to wakeup the
1093 scheduler by the specified task queue. Affected file
1094 lib/silcutil/silctask.[ch].
1096 * The silc_socket_host_lookup_start now wakes up the scheduler
1097 after adding the timeout task. Affected file is
1098 lib/silcutil/silcsockconn.c.
1100 * The silc_socket_host_lookup is synchronous now if the threads
1101 support is not compiled in. However, the callback is still
1102 called asyncronously through the scheduler, anyway. Affected
1103 file lib/silcutil/silcsockconn.c.
1105 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Added new function silc_socket_host_lookup to perform
1108 asynchronous IP and FQDN lookups for the socket connection.
1109 Affected files lib/silcutil/silcsockconn.[ch].
1111 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1114 that may or may not compile the mutex support in.
1116 Changed the silc_mutex_alloc interface. It allocates the
1117 mutex now to the sent pointer and returns TRUE or FALSE.
1119 Affected file lib/silcutil/silcmutex.h.
1121 * Wrote the SILC Task Queue interface to support multi-threads.
1122 Affected file lib/silcutil/silctask.[ch].
1124 * Wrote the SILC Scheduler to support multi-threads. Affected
1125 file lib/silcutil/silcschedule.c.
1127 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1129 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1130 in lib/silcutil/win32/.
1132 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Defined SILC Mutex API and SILC Thread API and implemented
1135 them for Unix. Affected files are
1136 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1137 lib/silcutil/unix/silcunixmutex.c and
1138 lib/silcutil/unix/silcunixthread.c.
1140 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Fixed the silc_server_remove_clients_by_server's channel
1143 key re-generation. The hash table handling was incorrect
1144 and would not work with many channels. Affected file is
1147 * Fixed some memory leaks around the server code.
1149 * Rewrote the silc_server_get_users_on_channel to support IPv6
1150 based Client ID's. Affected file silcd/server.c.
1152 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1153 specification. However, a separate document must be written
1154 to define the detailed signing procedure and the payload
1155 associated with the flag. Defined the flag to the
1156 lib/silccore/silcchannel.h as well.
1158 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1160 * Changed the dynamic tables to static size tables in the
1161 lib/silccrypt/silchmac.c.
1163 * Removed GCC dependencies from the code. A patch by cras.
1165 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Do not show the error "Error receiving packet bla bla"
1168 in server if it really was not an error (-2 means that reading
1169 is pending). Affected file silcd/server.c.
1171 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * Fixed a possible crash in silc_server_remove_clients_by_server
1174 in silcd/server.c. Fixed there also some memory leaks.
1176 * Fixed the silc_idlist_replace_client_id. It could replace
1177 wrong key in the hash table. Affected file silcd/idlist.c.
1179 * Do not check whether there are global users on the channel
1180 if the channel->global_users is FALSE. Affected functions
1181 silc_server_remove_from_one_channel and
1182 silc_server_remove_from_channels in silcd/server.c. Also,
1183 do not check if the removed client is local as we can be
1184 sure that global client was not removed from the channel
1185 and checking for global users is not needed.
1187 * The silc_server_remove_clients_by_server now re-generates
1188 the channel keys correctly for those channels that had
1189 clients removed from them. Affected file silcd/server.c.
1191 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Found the reason of random crashes in the server. We weren't
1194 ignoring the SIGPIPE signal (which can be sent in write())
1195 and it crashed the server. Affected file silcd/silcd.c.
1197 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Assure that sock->user_data is not NULL in the function
1200 silc_server_packet_send in silcd/packet_send.c.
1202 * Disconnect the remote connection if it could not be added
1203 to any ID lists in the server. The affected file is
1206 * Check in silc_server_packet_send[_real/dest] that the
1207 socket is not disconnecting and ignore the data if it is.
1208 Affected file silcd/packet_send.c.
1210 * Define inline to __inline on native WIN32 compilation.
1211 Affected file includes/silcwin32.h.
1213 * Added some explicit type casts for inline code since MSVC
1214 require them. Affected files lib/silcutil/silcbuffer.h,
1215 lib/trq/silcdlist.h and lib/trq/silclist.h.
1217 * Print warning in log files from now on if the packet
1218 decryption fails. Affected file silcd/server.c.
1220 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Changed the `say' client operation's interface to accept
1223 new `type' argument to indicate the type of the message sent
1224 by the library. The application may filter the library's
1225 messages according the type. The affected file is the
1226 lib/silcclient/silcapi.h.
1228 * Added two new functions to lib/silcclient/silcapi.h:
1229 silc_client_del_client and silc_client_del_client_by_id.
1230 Affected file lib/silcclient/idlist.c.
1232 * Moved the clientincludes.h from includes/ to silc/ and
1233 serverincludes.h from includes/ to silcd/.
1235 * The modes for the CMODE and CUMODE are now passed as
1236 uint32 for application with COMMAND_REPLY. The affected
1237 file is lib/silcclient/command_reply.c.
1239 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * /WHOIS without arguments shows client's own information.
1242 Affected file lib/silcclient/command.c.
1244 * Changed PING to not accept any arguments. The specs
1245 says that client can ping only the connected server so
1246 requiring an argument is not needed. Affected file is
1247 lib/silcclient/command.c.
1249 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1251 * Fixed a fatal bug in private message sending and reception
1252 encryption and decryption when using private message keys.
1253 The implementation was incorrect and did not follow the
1254 specification. It causd that some of the message were
1255 lost since it did not use the sending and receiving keys
1256 as the protocol suggests. This has been fixed and will cause
1257 incompatibilities with older clients when sending private
1258 message encrypted with private message keys. Affected files
1259 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1260 and various other in Irssi SILC Client.
1262 Added `responder' boolean argument to the functions
1263 silc_client_add_private_message_key[_ske] to indicate when
1264 the key is added as responder or initiator of the key
1267 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Removed the silc_ske_check_version function and created
1270 a SilcSKECheckVersion callback. Added also a function
1271 silc_ske_set_callbacks that is now used to set all SKE
1272 callbacks. The callback functions are not given to
1273 the SKE functions anymore, but this function is used to
1276 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1278 * Added `silc_version' argument to the silc_client_alloc
1279 to define the version of the application for the library.
1280 The library will use the version string to compare it
1281 against the remote host's (usually a server) version
1282 string. Affected file lib/silcclient/silcapi.h
1284 * Added the KE protocol context to Key Agreement context
1285 in client library so that we can abort the SKE if it
1286 is in process when we get timeout. Affected file is
1287 lib/silcclient/client_keyagr.c.
1289 * Do not resolve the client ID forever if it returns in the
1290 first time that such client does not exist. This was done
1291 for example with private message. Affected file is
1292 lib/silcclient/client_prvmsg.c.
1294 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Do not add regex.h for WIN32. The affected file
1297 includes/silcincludes.h.
1299 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1300 not work yet 100%. It generates the DLL's automatically
1301 when compiling with --with-win32 under cygwin.
1303 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1305 * lib/contrib/regex.c is not compiled on WIN32.
1307 * Added silc_net_get_socket_opt function to the
1308 lib/silcutil/silcnet.h.
1310 * Added includes/silcwin32.h for WIN32 specific includes
1313 * Do not use ptime structure or any of the posix process
1314 functions on WIN32 in lib/silccrypt/silrng.c.
1316 * Added silc_gettimeofday to provide generic function
1317 for struct timeval on all platforms. Added the function
1318 to lib/silcutil/silcutil.h.
1320 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1323 library as they clearly belong there. As a plus side we
1324 can make the actual socket connection routines platform
1327 Added also new generic function silc_socket_read and
1328 silc_socket_write (that used to be silc_packet_[read/write].
1329 The implementation of these are platform specific.
1331 * Added WIN32 specific routines of silc_socket_[read/write]
1332 to lib/silcutil/win32/silcwin32sockconn.c.
1334 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Added preliminary support for native WIN32 compilation under
1337 cygwin (using the -mno-cygwin option for GCC) to the
1338 ./configure.in.pre. The --with-win32 now prepares the
1339 compilation for native WIN32.
1341 * Rewrote the SILC Scheduler interface in the file
1342 lib/silcutil/silcschedule.h. The scheduler is now context
1343 based and does not have anymore any global static scheduler.
1344 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1345 and created lib/silcutil/win32 directory for WIN32 based
1348 * Added Unix specific network routines to the
1349 lib/silcutil/unix/silcunixnet.c and the old
1350 lib/silcutil/silcnet.c includes now only generic routines.
1352 Added WIN32 specific network routines to the
1353 lib/silcutil/win32/silcwin32net.c.
1355 * Added Unix specific utility functions from the
1356 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1358 * Added WIN32 SILC Scheduler to the file
1359 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1362 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Do not handle JOIN notify in the server if the target client
1365 is not registered (idata->registered == FALSE). The affected
1366 file is silcd/packet_receive.c.
1368 * Update the nickrec->founder in event_cumode in the Irssi SILC
1369 client. Affected file irssi/src/silc/core/silc-channels.c.
1371 * Fixed the CUMODE_CHANGE notify handling in the server when
1372 server and router are announcing their clients on channels.
1373 Now the mode changes are saved and notified correctly. The
1374 affected file is /silcd/packet_receive.c.
1376 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1377 They really did not replace the cache entry in the ID Cache.
1378 Now they do that. Affected file silcd/idlist.c.
1380 * Fixed the KICK notify handling in the Irssi SILC client to
1381 update the channel records so that the kicked client does not
1382 appear to be on the channel. The affected file is
1383 irssi/src/silc/core/silc-channels.c.
1385 * Always update the conn->current_channel when executing command
1386 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1388 * Fixed the KILL notify handling in Irssi SILC client to remove
1389 the killed client on all channels.
1391 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Fixed the silc_parse_command_line to remove extra spaces
1394 from the start and end of the arguments. Affected file is
1395 lib/silcutil/silcutil.c.
1397 * Cancel and free any active protocol in the function
1398 silc_server_close_connection. Affected file silcd/server.c.
1400 * Cancel and free any active protocol in the function
1401 silc_client_close_connction. Affected file is
1402 lib/silcclient/client.c.
1404 * Do not execute the KILL command for clients that are in
1405 history (ie. they are not in the network). Affected file is
1408 * Fixed KILL notify handling, client does not crash anymore.
1409 Affected file irssi/src/silc/core/silc-channels.c.
1411 * Reduced the default packet buffer size from 2048 to 1024 in
1412 lib/silccore/silcpacket.c.
1414 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1415 counter to the SKE context that is incresed when the SKE library
1416 performs async operation outside the library. If the outside
1417 process frees the SKE context and FREED status will be set
1418 and the library will detect after the sync operation that the
1419 libary is freed. The affected files are
1420 lib/silcske/silcske[_status].[ch].
1422 * Resolve the client entry information in the function
1423 silc_client_channel_message to assure that NULL pointer is not
1424 passed as client entry to the application. */
1426 * Fixed the task timeout calculation to assure that there is
1427 never negative timeouts. The affected file is
1428 lib/silcutil/silcschedule.c.
1430 * Fixed the channel user mode notification sending in server.
1431 It was sent point-to-point to the router (or to server by router)
1432 but it needs to be destined to a channel. The routines now
1433 supports sending the channel user mode notifys to the channels
1434 when announcing clients and channels. Affected files are
1435 silcd/server.c and silcd/packet_receive.c.
1437 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1438 It did not actually replace the old channel entry in the cache.
1439 Affected file lib/silcclient/client_notify.c.
1441 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Fixed a possible crash in silc_packet_send_prepare. It now
1444 assures always that there is enough space in the buffer and
1445 at the tail area of the buffer (for MAC).
1447 Fixed the inbound buffer reallocation in silc_packet_read.
1448 It was old code and did not handle the reallocation correctly.
1451 The affected file is lib/silccore/silcpacket.c.
1453 * Fixed buffer overflow in silc_parse_nickname in the file
1454 lib/silcutil/silcutil.c.
1456 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * make install generates new server keys only if there is not
1461 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1464 Added check that if the NOREPLY is set then we will not send
1465 the away message. This avoids infinite loop of away messages
1466 if both clients are away. The affected file is
1467 lib/silcclient/client_prvmsg.c.
1469 * Fixed client crash if /NICK was given without arguments.
1470 Affected file lib/silcclient/command.c.
1472 * Server does not send the invite list in INVITE command back
1473 to the client if the list was not altered. Added this notion
1474 to the protocol spec as well. Affected file silcd/command.c.
1476 Fixed possible crash in INVITE command by checking the
1477 value of silc_server_get_client_route command.
1479 * Fixed the INVITE notify type handling. The arguments are now
1480 taken in correct order and client does not crash. The affected
1481 file is irssi/src/silc/core/silc-channels.c.
1483 Removed the "Inviting xxx to channel" message from the
1484 client library away and let the application handle it.
1485 Affected file lib/silcclient/command.c. Added that message
1486 to Irssi SILC client's message formats.
1488 * Fixed CMODE command crash in client. It now checks the
1489 amount of arguments correctly and does not crash. The affected
1490 file is lib/silcclient/command.c.
1492 * Do not create new channel automatically in silc_channels_join
1493 but check whether the channel by that name already exists.
1494 Affected file irssi/silc/core/silc-channels.c.
1496 * Do not send the SERVER_SIGNOFF to router if the disconnected
1497 entity was the router. Affected file silcd/server.c.
1499 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1500 SILC client as it was missing from there.
1502 Added the handling of the KICK notify to the Irssi SILC client
1503 as it was missing. Added "you have been kicked" message to
1504 Irssi SILC client's message modules formats.
1506 Added the handing of the KILL notify to the Irssi SILC client
1507 as it was missing. Added the kill message module formats
1510 The affected file is irssi/src/silc/core/silc-channels.c.
1512 * The router did not save the channel mode the server announced.
1513 Affected file silcd/packet_receive.c.
1515 * Fixed a possible crash in INFO command in server. If the
1516 server did not provide the server info it crashed. Affected
1517 file silcd/command.c.
1519 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Fixed the GETKEY command in the server to check also the
1522 global list. Otherwise the GETKEY would not work correctly
1523 in normal SILC server. Affected file silcd/command.c.
1525 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Fixed GETKEY crash, it crashed if the command did not succseed.
1529 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1531 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1532 is now real and not just an macro interface to GMP.
1534 Removed the entire GMP from the source tree and imported new
1535 NSS MPI library instead. Reason for removing GMP is that it is
1536 extremely large and compiles extremely slow. The NSS MPI
1537 is only a few files and compiles in less than 10 seconds.
1538 The speed is also about the same as GMP. The MPI is imported
1539 to lib/silcmath/mpi.
1541 If the system has GMP installed we will still use the GMP.
1542 If it is not then the NSS MPI will be compiled.
1544 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Merged a long nickname (127 characters long) crash bugfix from
1547 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1549 * Merged a freed memory reference bugfix from Irssi CVS tree.
1550 Affected file irssi/src/core/commands.c.
1552 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Added the server's public key sving and verification to the
1555 server when performing the SKE. This was missing and the
1556 remote server's (or router's) public key was accepted without
1557 checking whether we have it previously or trust it at all.
1558 Affected file silcd/protocol.c.
1560 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1562 * Check in the silc_server_timeout_remote if protocol is active
1563 and make sure that the protocol's final callback is called so
1564 that all memory if freed. Affected file silcd/server.c.
1566 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * silc_server_whois_send_reply crashed the server if the nickname
1569 was 127 characters long. Affected file silcd/command.c.
1571 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Added sanity check to the silc_server_new_client. If the hostname
1574 is provided inside username then check that the provided hostname
1575 really is the same as the resolved one. If the hostname was not
1576 resolved then check it from the public key. Affected file is
1577 silcd/packet_receive.c.
1579 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1580 if the server disconnected us and the connection is not valid
1581 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1583 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1584 the library to the lib/silcutil/silcutil.[ch].
1586 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Close log file after open. Affected file
1589 lib/silcutil/silclog.c.
1591 * Check whether sock == NULL in silc_client_send_packet and return
1592 if it is. Affected file lib/silcclient/silcclient.c.
1594 * Check rec->entry == NULL in the Irssi SILC Client before
1595 sending the channel message. Affecte file is
1596 irssi/src/silc/core/silc-servers.c.
1598 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Merged a splitted window bugfix from Irssi CVS tree. The
1601 affected file is irssi/src/fe-text/textbuffer-view.c.
1603 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1604 It did not print nickname.
1606 * Improved the distributions system a bit.
1608 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1611 irssi/src/fe-text/gui-window.c.
1613 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1614 to in-active server. The affected file is
1615 irssi/src/silc/core/client_ops.c.
1617 * Resolve the client in USERS command reply if the entry does
1618 not have username resolved. The affected file is
1619 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1620 command to WHOIS command to really resolve stuff. The USERS
1621 is not used any more in any critical section so WHOIS can
1622 be used even though it might be slower than IDENTIFY.
1624 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1627 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Changed the protocol API a bit more consistent in the
1630 lib/silccore/silcprotocol.[ch].
1632 * Changed the following headers to ROBODoc format:
1634 lib/silccore/silcpayload.h
1635 lib/silccore/silcprotocol.h
1636 lib/silccore/silcsockconn.h
1638 All core library headers are now formatted.
1640 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Fixed a bug in Irssi SILC client; do not show that you are
1643 server/router operator if you really are not. Affected file is
1644 irssi/src/silc/core/client_ops.c.
1646 * Renamed silc_command_free_payload to silc_command_payload_free.
1647 Affected file lib/silccore/silccommand.h
1649 * Added silcmath.h to include the prototoypes of various routines
1650 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1653 * Changed the following headers to ROBODoc format:
1655 lib/silccore/silcchannel.h
1656 lib/silccore/silccommand.h
1657 lib/silccore/silcid.h
1658 lib/silccore/silcidcache.h
1659 lib/silccore/silcmode.h
1660 lib/silccore/silcnotify.h
1661 lib/silccore/silcpacket.h
1662 lib/silcmath/silcmath.h
1664 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Added checking to the server code not to start the server if
1667 ciphers and stuff are not configured properly. Affected files
1668 silcd/serverconfig.[h] and silcd/server.c.
1670 * Changed the layout of the header files of the public interfaces
1671 in the SILC libraries. The new layout supports ROBODoc
1672 documentation tool (and some others) so that it is easy to create
1673 a library reference manual. All the other headers and source
1674 code must still follow the CodingStyle document. Also source
1675 code must not include these ROBODoc stuffs, only the headers.
1676 Furthermore, all public interface headers must now be named
1677 by using `silc' prefix, example: silcapi.h, silccipher.h.
1678 Some files were renamed due to this. All the other headers
1679 must not be used as public interfaces. I will update the
1680 CodingStyle document later. Changed following headers, so far:
1682 lib/silcclient/silcapi.h
1683 lib/silccore/silcauth.h
1684 lib/silccore/silcprivate.h
1685 lib/silccrypt/silcdh.h
1687 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Removed silc_client_packet_send_flush from the client library
1692 as it is not needed. Affected file lib/silcclient/client.[ch].
1694 * Added printing of message of unresolved authentication method
1695 to the Irssi SILC client. Added it to the module formats.
1696 Removed the same message from the client library.
1698 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Added new distribution feature, DISTLABEL. Every distribution
1701 can define own preprocessor label that can be used in the
1702 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1703 file distributions, acconfig.h.pre and prepare.
1705 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Added Makefile.defines_int to include the actual definitions
1708 for Makefile.defines.in. Tested the new distribution system,
1709 created distributions and tested installation.
1711 * Added AWAY message printing to the Irssi SILC client. Added
1712 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1714 * Added SCONNECT command to call the SILC's CONNECT command.
1715 Cannot use CONNECT directly since Irssi uses that internally.
1716 Affected file irssi/src/silc/core/silc-servers.c.
1718 Added ACTION local command. It is same as ME command but takes
1719 the channel as mandatory argument.
1721 Rewrote some of the Irssi's help files to suite for SILC
1724 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Added Makefile.defines[.in] that should for now on be included
1727 in all Makefile.am file in the source tree. That file includes
1728 all common compilation definitions for SILC source tree.
1730 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Minor changes to the ./prepare script to change the package
1733 name according the distribution name to the configure.in.
1735 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Created new distribution system. Added file `distributions'
1738 that defines all the distributions that can be created out of
1739 the SILC source tree. The ./prepare script now reads that
1740 file to determine how to prepare the distributions. The
1741 first argument to the ./prepare is the name of the distribution
1742 and second is the version of the distribution. If given
1743 without arguments it creates the default (toolkit) distribution
1744 with the default version (defined in ./prepare).
1746 All Makefile.am files that are subject to the distributions
1747 are now named as Makefile.am.pre. These are ./Makefile.am
1748 and lib/Makefile.am. Others may be changed later.
1750 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Added invite list, ban list, some key management and connection
1753 error message printing to module formats in the Irssi SILC client.
1755 * Added new silc_client_set_away_message to set the away message
1756 that is back to the person who sent private message. The
1757 affected file lib/silcclient/silcapi.h and the
1758 lib/silcclient/client_prvmsg.c.
1760 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Fixed the private message sending in the Irssi SILC client,
1763 added local command KEY to the Irssi SILC client.
1765 Added key management and key agreement message formats to the
1766 irssi/src/fe-common/silc/module-formats.[ch].
1768 Added USERS (alias WHO) printing, server/router operator
1769 indication and LIST command printing to the module formats.
1771 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * Fixed channel joining notify handling, cumode notify handling
1774 from Irssi SILC client.
1776 * Added SILC specific module-formats to the Irssi SILC client so
1777 that SILC specific message hilighting, colors etc is possible.
1778 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1780 Added channel mode, channel user mode, actions, notices,
1781 whois and whowas printing to the the module-formats.c.
1783 * Fixed a bug in channel deletion in the server. The channel
1784 is not left to the cache even if the channel founder auth mode
1785 is set when there are no users anymore on the channel. Affected
1786 file silcd/server.c.
1788 * The silc_net_localhost now resolves the entire hostname including
1789 the domain name. Affected file lib/silcutil/silcnet.c.
1791 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Changed the ask_passphrase client operation to be ascynchronous.
1794 It has now a completion callback and a context that the
1795 application must call after it has got the passphrase from
1796 the user. Affected files lib/silcclient/silcapi.h,
1797 lib/silcclient/protocol.c, lib/silcclient/command.c and
1800 Added SilcAskPassphrase callback that the application calls
1801 to deliver the passphrase to the library.
1803 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1804 The public key verification and especially a certificate
1805 verification is asynchronous procedure.
1807 Added new SILC_SKE_STATUS_PENDING status to indicate the
1808 request is pending and a callback will be called to finalize
1811 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1812 indicate that remote end did not send its public key (or
1813 certificate), even though we require it. Added check for this
1814 condition in the SKE. This was a security bug, now fixed.
1816 Defined new SilcSKEVerifyCbCompletion callback that is called
1817 when the verification process is completed.
1819 The affected files lib/silcske/silcske_status.h and
1820 lib/silcske/silcske.[ch].
1822 * Changed the verify_public_key client operation to be async
1823 as well. Defined SilcVerifyPublicKey callback that is used to
1824 indicate the success of the public key verification process.
1826 Changed the server and client to use the new async client
1829 * Changed the Irssi SILC client's internal scheduler to be called
1830 twice as many times as it used to be. As a result the client
1831 should be a bit faster now. Affected file is
1832 irssi/src/silc/core/silc-core.c.
1834 * Added support to Irssi SILC client of asynchronous public key
1835 verification and passphrase inquiry. Affected file is
1836 irssi/src/silc/core/silc-core.c.
1838 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Do not say "You have left channel %s" in client library.
1841 Moved it to the application. Affected files are
1842 lib/silcclient/command.c and silc/client_ops.c.
1844 * Fixed silc_client_get_clients. Command context was not
1845 duplicated and was freed memory in the callback. Affected
1846 file lib/silcclient/idlist.c.
1848 * Do not say "you are now talking..." on JOIN command in the
1849 client library. The appliation must handle it.
1851 * Do not say ".. changed topic to" in command reply in the
1852 client libary. The application must handle it.
1854 * Fixed TOPIC command sending in the client library.
1856 * Fixed a memory leak in silc_client_command_free in the file
1857 lib/silcclient/command.c.
1859 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Imported a modified version of Irssi client to the source tree.
1862 The Irssi will be used to create a new client called
1863 Irssi SILC. Imported to irssi/.
1865 Added silc_core_init_finish function to the Irssi. Affected
1866 file irssi/configure.in.
1868 A lot changes in the Makefile.ams around the irssi tree.
1870 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Do not rehash if the new size is same as the old size of the
1873 hash table, in the silc_hash_table_rehash*. The affected file
1874 lib/silcutil/silchashtable.c.
1876 * Replaced hash_table_del_by_context calls from the server
1877 (when channel->user_list and client->channels) to the
1878 hash_table_del as it is sufficient and faster.
1880 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Added silc_hash_table_list, silc_hash_table_get and the
1883 SilcHashTableList structure to provide an alternative way to
1884 traverse the hash table. The affected files are
1885 lib/silcutil/silchashtable.[ch].
1887 * Changed the server's idlist routines to use the hash table
1888 routines to optimize the code.
1890 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Replaced the client entry's `channel' list and channel entry's
1893 `user_list' list to hash tables for optimized lookup. Changed
1894 the code to use the hash table interface around the code.
1895 Affected file lib/silcd/idlist.[ch].
1897 * Added `auto_rehash' boolean argument to the function
1898 silc_hash_table_alloc to indicate whether the hash table should
1899 auto-rehash when it thinks is appropriate time. It will
1900 increase the hash table size if the there is twice as much
1901 entries in the table than the size of the table, and will
1902 decrease the size if there are twice as less entries than
1903 the size of the table.
1905 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1907 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1909 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * silc_idcache_purge_by_context deletes the entry now by context
1912 as it is supposed to do. Affected file lib/silccore/idcache.c.
1914 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1915 client is not anymore valid (WHOWAS givens the info) and not
1916 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1918 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Removed the `data' and `data_len' arguments from the ID Cache
1921 interfaces and added `name' argument. ID Cache does not handle
1922 anymore the binary data only a names associated with given ID.
1924 * When hashing a Client ID with silc_hash_id the entire ID is
1925 not hashed anymore, instead only the hash of the Client ID is
1926 hashed. This way we can access the Client ID from the cache
1927 with Client ID but with the hash of the ID (which is a hash of
1928 the nickname) as well without any difference in performance.
1930 Added also silc_idcache_find_by_id_one_ext to do one on one
1931 searching when we have the actual ID. Added also function
1932 silc_hash_client_id_compare. The affected files are
1933 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1935 * When hashing the name associated with a ID it is always done
1936 in lowercase. This way we can access the cache without worrying
1937 about case-sensitivity, even though, for example nicknames are
1940 * Fixed a bug in server with channel message sending. It put
1941 wrong ID type as destination ID. The affected file
1942 silcd/packet_send.c.
1944 * silc_idcache_del_by_context now deletes from all hash tables
1945 by context. Affected file lib/silccore/idcache.c.
1947 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Changed the client library to use the new ID Cache interface.
1950 Changes around the source tree.
1952 * Added silc_hash_table_rehash_ext to rehash with specific
1953 hash function. Affected file lib/silcutil/silchashtable.[ch].
1955 * Added silc_hash_string_compare to compare two strings in the
1956 hash table. Affected file lib/silcutil/silcutil.[ch].
1958 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Added new function silc_idcache_del_by_context into the
1961 lib/silccore/idcache.[ch].
1963 * Changed the server's ID list routines to use the new ID Cache
1964 interface. Changes around the source tree.
1966 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Added silc_hash_table_del[_by_context]_ext functions in to the
1969 lib/silcutil/silchashtable.[ch].
1971 Removed silc_hash_table_find_all* routines and added new
1972 silc_hash_table_find_foreach to replace them.
1974 Added silc_hash_table_replace_ext function as extended
1975 replacing function. Separated the simple hash table interface
1976 from the extended hash table interface in the file
1977 lib/silcutil/silchashtable.h.
1979 * Fixed minor bugs and changed it to use some of the new
1980 hash table functions in lib/silccore/idcache.c
1982 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Added new function silc_hash_table_find_all to return all keys
1985 in the hash table by the specified key. As the hash table is
1986 collision resistant it also makes it possible to have several
1987 duplicate keys in the hash table. This function may be used to
1988 find all of the keys from the hash.
1990 Added user_context arguments to the SilcHashFunction,
1991 SilcHashCompare and SilcHashDestructor to deliver user specified
1994 Added new fuctions silc_hash_table_find[_all]_ext to do
1995 extended lookup with specified hash and compare functions and
1996 specified user contexts.
1998 Added new function silc_hash_table_add_ext to add the key
1999 with specified hash function and user context.
2001 Added new function silc_hash_table_foreach to traverse all
2002 entrys in the hash table. Added SilcHashForeach callback
2005 Added new function silc_hash_table_del_by_context to delete
2006 the entry only if the context associated with the key matches.
2008 Affected files are lib/silcutil/silchashtable.[ch].
2010 * Removed silc_hash_[server/client/channel]_id and added just
2011 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2012 silc_hash_id_compare to compare two ID's using as the hash table
2013 comparison function. Added also silc_hash_data to hash
2014 binary data and silc_hash_data_compare to compare it.
2016 * Removed silc_idlist_find_client_by_hash as it is not needed
2017 anymore. Affected file silcd/idlist.[ch].
2019 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2020 to use internally the SilcHashTable. The new ID Cache is a lot
2021 faster than the old one. Some of the ID Cache interface was also
2022 rewritten and obsolete and stupid functions were removed.
2024 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Added entry_count field to the SilcHashTable to keep the number
2027 of the entries in the table. Implemented the function
2028 silc_hash_table_rehash. Added new function
2029 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2031 Fixed a minor bug in silc_hash_table_free.
2033 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2034 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2035 into the lib/silcutil/silcutil.[ch].
2037 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2039 * Implemented a collision resistant hash table into the
2040 lib/silcutil/silchashtable[ch]. See the header and the source
2041 for the SilcHashTable API.
2043 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Merged dotconf version 1.0.2 into lib/dotconf.
2047 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Do not compile anything in lib/silcsim/* if the SIM support
2050 is not enabled. The tree should now compile without problems
2053 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Compiled the SILC under cygwin. Compiled and tested briefly
2056 without problems. More tests needed. The SIMs didn't compile
2059 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2061 * Fixed possible crash in silc_get_username in the
2062 lib/silcutil/silcutil.c.
2064 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Fixed a va_arg in silc/client_ops.c.
2068 * Oops, RC5 routines were named AES and caused some problems
2069 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2071 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Added new SilcIDIP structure into the lib/silccore/id.h and
2074 replaced the old `ip' fields from all SILC ID's to that type.
2075 This is a step towards IPv6 support.
2077 The silc_id_get_len takes now the ID as an extra argument.
2078 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2079 both IPv4 and IPv6 based ID's.
2081 The affected files are lib/silccore/id.[ch] and other files
2082 around the tree using these routines.
2084 * Removed the ID length arguments in server from various
2085 silc_server_send_notify_* routines -> they are not needed
2088 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Fixed memory leak in silc_encode_pem_file in the file
2091 lib/silcutil/silcutil.c.
2093 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Check minor version as well in the SKE. Affected files are
2096 silcd/protocol.c and lib/silcclient/protocol.c.
2098 * Added --identifier option to the server so that an identifier
2099 can be when creating the public key for the server. Affected
2100 file is silcd/silcd.c.
2102 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2103 lib/silccrypt/silcpkcs.c.
2105 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Register default ciphers and stuff when using -C option with
2108 the server. Affected file sildc/silcd.c.
2110 * Put back the servers public key filename format, it is better
2111 than the new one. For now, the client keys are saved with the
2112 new filename format. The affected file silc/client_ops.c.
2114 * Implemented the Cipher API for the rest of the ciphers that
2115 did not implement it or implemented it the wrong way.
2117 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Register default ciphers and stuff when using the -S option
2120 in the client. Affected file silc/silc.c. Same also when
2121 creating new key pair with -C option.
2123 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Fixed the silc_verify_public_key client operation function to
2126 save the public keys differently. The fingerprint is now
2127 used as filename and not the hostname. This way also the
2128 client keys are saved uniquely and not with hostnames. The
2129 affected file is silc/client_ops.c.
2131 * Trimmed the silc_hash_fingerprint function to remove extra
2132 whitespaces from the end of the fingerprint. The affected
2133 file is lib/silccrypt/silchash.c.
2137 * Added silc_cipher_register_default function to register all
2138 default ciphers. It can be used when configuration files
2139 does not exist and the application does not want any specific
2140 ciphers in any specific order.
2142 The SilcDList is now used as silc_cipher_list dynamically
2143 allocated cipher list. Removed the static list all together
2144 and now all ciphers must be allocated to the dynamic list.
2145 The silc_cipher_alloc routine was changed to check only the
2148 All silc_cipher_* routines that used to return int returns
2151 The affected files lib/silccrypt/silccrypt.[ch].
2153 * The same thing was done to silc_hash_* as for silc_cipher_*
2154 routines. Affected files lib/silccrypt/silchash.[ch].
2156 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2157 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2158 Added also silc_pkcs_[un]register[_default] functions.
2159 Removed the data_context from the PKCS API.
2161 * Added silc_hmac_register_default function to register default
2162 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2163 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2164 to unregister all hmacs at once.
2166 * Register the default ciphers, hash functions, PKCSs and HMACs
2167 if client's configuration file does not exist. The affected
2170 * The client did not load the hash functions from the SIM
2171 modules at all. Added support for this. Affected file is
2172 silc/clientconfig.c.
2174 * When decoding public key with silc_pkcs_public_key_decode, check
2175 the supported algorithm only if PKCS are registered. Affected
2176 file lib/silccrypt/silcpkcs.c. The same was done with the
2177 silc_pkcs_private_key_decode.
2179 * Fixed the SILC List routines to keep the list always in order.
2180 It used to change the list's order when traversing the list but
2181 not it preserves the order. Affected file lib/trq/silclist.h.
2183 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2185 * Added the client library to use the SilcSocketConnection's
2186 reference counter (by silc_socket_dup) to prevent the bug that
2187 the socket object may be freed underneath async operation.
2189 * The name resolv library checking fixes in the configure.in.pre.
2192 * Created new version of the protocol drafts for future
2193 development. The -03 drafts are the ones that will be changed
2194 in the trunk now and the -02 will remain as they are.
2196 * Send list of CUMODE notifys to the router when announcing
2197 the channel users to the router. Affected file silcd/server.c.
2198 If the router receiving channel founder CUMODE for a channel
2199 that already has channel founder it will send CUMODE notify
2200 to the sender to remove the channel founder rights from the
2201 announced client. Affected file silcd/packet_receive.c.
2203 * The CUMODE notify may now use Server ID as well as the entity
2204 who changes the mode. Updated protocool specs.
2206 * Updated INSTALL and README files.
2208 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * New web pages in the http://silc.pspt.fi. The pages was
2215 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Implemented the [DenyConnectin] config section in the server.
2218 Added silc_server_config_denied_conn to check whether incoming
2219 connection is denied. Affected file silcd/serverconfig.[ch].
2221 * Do not check the ports when checking the incoming configuration
2222 data if the port is 0, meaning any. Affected file is
2223 silcd/serverconfig.c.
2225 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Fixed buffer overflow in silc_string_compare in the file
2228 lib/silcutil/silcutil.c.
2230 * Fixed double free in silc_server_command_leave in the file
2233 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Fixed the version checking in the server. Affected file is
2238 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Fixed the configuration data fetching when accepting new
2241 connections in the server. Affected file silcd/server.c.
2243 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Added `sender_entry' argument to the function
2246 silc_server_packet_relay_to_channel so that we can check
2247 whether some destination actually belongs to the same route
2248 the sender belongs (ie, we must not resend the packet to the
2249 sender). Affected file silcd/packet_send.[ch].
2251 * Added `servername' field to the SilcClientEntry in the server
2252 to hold the name of the server where client is from. Affected
2253 file is silcd/idlist.h.
2255 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Moved the channel message encrypting in the router betwen
2258 router connections from silc_server_channel_message to the
2259 silc_server_packet_relay_to_channel since we want to check
2260 whether we have anybody channel before encrypting anything.
2261 Affected files silcd/packet_[receive/send].c.
2263 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * Fixed the [AdminConnection] server config section to support
2266 multiple entries. Affected file silcd/serverconfig.c.
2268 * Added support into the server to check the validity of the
2269 incoming connection before executing any KE or authentication
2272 * The connection configuration is now saved to the KE and
2273 connection auth protocol contexts and not fetched anymore in
2274 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2276 * The local hosts listenning address and port is also resolved
2277 now when starting the server. We want to have the socket object
2278 to include the real address and port for the listener. Added
2279 new function silc_net_check_local_by_sock into the files
2280 lib/silcutil/silcnet.[ch].
2282 * Fixed a broadcast bug in server -> do not broadcast if we
2285 * Fixed a routing bug. Do not route broadcast packets ever.
2286 Broadcast packets must be processed always and not routed since
2287 they may be destined to some other host than yourself and thus
2288 would get routed without no good reason. Affected file is
2291 * Added function silc_server_config_is_primary_route to check
2292 whether primary router connection has been configured (a router
2293 configuration that we are initiating). If there is not, we
2294 will assume that there is only two routers in the SILC network
2295 and we will use the incoming router connection as our primary
2296 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2298 * Changed the order of the broadcasting. Broadcast _after_ the
2299 packet has been processed not before. Affected file is
2302 * Fixed a [ClientConnection] parsing bug. The port was never
2303 parsed correctly thus resulting to port 0. Affected file
2304 silcd/serverconfig.c.
2306 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2307 argument and did not set the broadcast packet flag. Affected
2308 file silcd/packet_send.c. Fixed same bug in the function
2309 silc_server_send_notify as well.
2311 * If we receive NEW_ID packet for our own ID in the server, ignore
2314 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Removed the nickname from the Private Message Payload.
2319 Updated the code and the protocol specs.
2321 * Updated protocol specs for submitting to the IETF.
2323 * Tweaked the Random Number Generator a bit. Affected file
2324 lib/silccrypt/silcrng.c. Exported a new function
2325 silc_rng_[global]_add_noise which can be used to add more
2328 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Do not parse packets with different timeout when protocol
2331 is active -> may cause problem with rekey. Affected file
2334 * When server receives signoff notify it must not create
2335 new channel key if the client is on any channels since the
2336 sender of the signoff notify will create it.
2338 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added printing of error messages during SKE protocol from the
2341 failure packet sent by server during SKE. Affected file
2344 * Removed the client's failure_callback handling with timeout
2345 and handle it immediately when received.
2347 * The SKE library returned wrong type in SUCCESS and FAILURE
2348 packets. They must be 32 bit MSB not 16 bit MSB.
2350 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Ok, rewrote the logic of the re-key and now it seems to work.
2353 I tested it on high traffic with frequent re-keys without
2354 problems. Added hmac_receive (and renamed hmac to hmac_send)
2355 in SilcClientConnection in lib/silcclient/client.h and
2356 in SilcIDListData in silcd/idlist.h. Also, removed the
2357 SilcPacketParserContext's cipher and hmac fields as they are
2358 not needed anymore and actually caused some problems when
2359 the ciphers and hmac's changed underneath the packet parser.
2361 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * If re-key protocol is active then process the incoming packets
2364 synchronously since we must assure that icoming packets encrypted
2365 with the old key is processed before the new keys is set to
2366 use. This is true other packets than for REKEY packets.
2367 Affected file silcd/server.c. The same was done to client library
2368 as well, affected file lib/silcclient/client.c.
2370 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Fixed bug in client and server to accept the force send if
2373 the packet is send from silc_[server/client]_packet_process
2374 function. Otherwise the packets are never delivered, oops.
2376 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Disable force sending of packets when REKEY protocol is active.
2379 We must assure that no packet is sent directly when rekey is
2380 performed. All packets must be sent through packet queue.
2381 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2382 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2383 function is silc_[server/client]_packet_send_real to check
2386 * Replaced the SIM paths from example config files to
2387 /usr/local/modules. Also, make install creates now
2388 /usr/local/silc/logs directory to hold all the SILC server
2391 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2393 * Made the configure.in.pre work on Solaris. Patch by salo.
2395 * Made all ciphers compatible with non-x86 machines. Defined
2396 CBC mode macros into lib/silccrypt/ciphers_def.h.
2398 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2400 * Fixed the make install.
2402 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * When MAC computation fails the silc_packet_decrypt returned 0
2405 even though it was supposed to return -1. Fixed this. The
2406 affected file is lib/silccore/silcpacket.c.
2408 * Do not replace the config files in /etc/silc (in make install)
2409 if they already exist. Affected file ./Makefile.am.
2411 * Do not send re-key packets immediately but through packet queue.
2412 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2414 * Changed silc_net_check_host_by_sock to return FALSE if the
2415 IP/DNS could not be resolved. Though, it returns the IP address
2416 now even if it could not resolve it (but returns also FALSE).
2417 Affected file lib/silcutil/silcnet.[ch].
2419 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Added silc_pkcs_decode_identifier to decode the public key's
2422 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2423 Added also silc_pkcs_free_identifier. Added also new context
2424 SilcPublicKeyIdentifier.
2426 * Added -S option to the silc client. It is used to dump the
2427 contents of the specified public key file.
2429 * Changed the PKCS api to return the public key length when
2430 setting the public key.
2432 * Fixed a fatal bug in the public and private key file loading.
2433 Affected file lib/silccrypt/silcpkcs.c.
2435 * Execute the packet parsing for client with zero (0) timeout
2436 if the protocol is active. Affected file silcd/server.c.
2438 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Made the key generation options to the silcd program. Added
2441 -C option, equivalent to client's option.
2443 * Added new [ServerKeys] config section to the server. It
2444 configures the server's public and private key.
2446 * Defined generic Public Key Payload into the protocol
2447 specification to send specific type of public keys and
2450 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2451 public key or certificate.
2453 * Implemented the GETKEY command to the server and to the
2454 client library and on user interface.
2456 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2458 * Made preliminary `make install' work.
2460 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Added SilcServerRekey context into silcd/idlist.h.
2464 * Added the PFS support as defined in the specification to the
2465 SKE protocol. Affected files lib/silcske/*.c.
2467 * Added `ske_group' field to the SilcServerRekey context to hold
2468 the number of the SKE group that is used with PFS in re-key.
2469 Affected file silcd/idlist.h.
2471 * Added PFS re-key support to the server. Affected file is
2474 * Added silc_protocol_cancel to cancel execution of the next
2475 state of the protocol. Affected file is
2476 lib/silccore/silcprotocol.[ch].
2478 * Added the re-key support with and without PFS to the client
2479 library. Re-key is performed once in an hour, by default.
2481 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2482 Added silc_client_rekey_callback and silc_client_rekey_final.
2483 Affected files are lib/silcclient/protocol.[ch] and
2484 lib/silcclient/client.[ch].
2486 * Removed the `hmac_key' and `hmac_key_len' fields from the
2487 SilcClientConnection structure; not needed. Affected file is
2488 lib/silcclient/client.h.
2492 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Do not ask whether user wants to use the negotiated private key
2495 for private messages, just use it. Affected file is
2496 silc/local_command.c.
2498 * Added `send_enc_key' and `enc_key_len' fields to the
2499 SilcIDListData structure since they are needed in the re-key
2500 phase. Affected file is silcd/idlist.[ch].
2502 * Implemented the simple re-key protocol into the server.
2503 Affected files silcd/server.c and silcd/protocol.[ch]. The
2504 re-key will be performed once in an hour, by default.
2506 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2507 Added silc_server_rekey, silc_server_rekey_callback and
2508 silc_server_rekey_final.
2510 * Removed Tunneled flag from the protocol. Updated the code
2511 and the specifications.
2513 * Adde `pfs' field to the SilcIDListData to indicate whether
2514 the PFS is to be performed in the re-key. Affected file is
2517 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2520 int64 of at least the xintXX size. If void * is less that 4
2521 bytes uint32 * will be used. Defined bool as boolean.
2523 * Changed _ALL_ unsigned long and unsigned int to uint32,
2524 unsgined short to uint16 in the source tree.
2526 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2527 not handle clients that has entry->data.registered == FALSE.
2528 They are not in the network anymore. Affected file is
2531 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Implemented the sending of the SERVER_SIGNOFF notify in the
2534 server. Affected file is silcd/server.c.
2536 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2537 Added also silc_notify_payload_encode_args into the
2538 lib/silccore/silcnotify.[ch].
2540 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2541 Affected file silcd/packet_receive.c.
2543 * Implemented the SERVER_SIGNOFF notify handling in the client
2544 library. Affected file lib/silcclient/client_notify.c. Also,
2545 implemnted the printing of the SERVER_SIGNOFF info to the
2546 application. Affected file silc/client_ops.c.
2548 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2549 if the deleting was successful. Affected file silcd/idlist.[ch].
2551 * Added support for public key authentication in the connection
2552 authentication protocol in the client library. Affected file
2553 lib/silcclient/protocol.c.
2555 * Changed the server's silc_idlist_get_clients_by_* interface
2556 to support already allocated array so that new entries may be
2557 added to pre-allocated array. Affected file silcd/idlist.[ch].
2558 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2559 and command replies.
2561 * All command reply functions in the server now calls the
2562 pending command callback even if error occured. This way the
2563 error will be delivered to the client as well. Affected files
2564 silcd/command.c and silcd/command_reply.c.
2566 * Fixed INFO command to return local server's info if no server
2567 was provided. Affected file lib/silcclient/command.c.
2569 * Removed RESTART command for good. Updated the code and the
2572 * Rewrote parts of the task system. It is a bit simpler now.
2573 Removed unsued task priorities. The affected files are
2574 lib/silcutil/silctask.[ch].
2576 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Moved the USERS printing from the library to the application.
2579 Affected files lib/silcclient/command.c and silc/client_ops.c.
2581 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Added channel key re-key support. The re-key is perfomed
2586 only by the router and is done once in an hour. Added `rekey'
2587 field to the SilcChannelEntry in the server. Affected files
2588 silcd/server.c and silcd/idlist.h.
2590 * Added silc_task_unregister_by_context into the file
2591 lib/silcutil/silctask.[ch].
2593 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added SILC_UMODE_GONE mode to indicate when the client is not
2596 present in the SILC network. Added also support to the local
2597 command AWAY that will set this mode. Added support of showing
2598 "xxx is gone" in WHOIS command. The USERS command shows the
2599 gone status as well.
2601 * Fixed setting server and router operator privileges in the
2602 server's UMODE command. Affected file silcd/command.c.
2604 * Merged the SKE KE1 and KE2 payloads into one payload. The
2605 new KE payload is equivalent to the old KE2 payload.
2607 Cleaned up the SKE Start Payload parsing. It now uses the
2608 simple buffer unformatting to do the parsing. A lot faster
2611 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2612 to the SKE that is used to indicate whether both of the SKE
2613 parties should perform authentication. By default only the
2614 responder performs authentication. By setting this flag also
2615 the initiator must do authentication. By default it is unset
2616 since in normal SKE case, client to server connection, only
2617 the responder should do authentication. When doing SKE between
2618 two clients both should perform authentication. Updated the
2619 code and the protocol specs.
2621 * A little fix to IDENTIFY command in the server. Search the
2622 client first by hash not nickname. Affected file is
2625 * Fixed the silc_client_close_connection to support closing
2626 the client to client connections wihtout deleting too much
2627 data. Affected file lib/silcclient/client.c.
2629 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2630 are received if protocol used to be active but is not anymore
2631 the application would crash due to NULL pointer dereference.
2632 Affected files silcd/server.c and lib/silcclient/client.c.
2634 * Added `hash' field to the SilcClientConnection to include
2635 the hash function negotiated in the SKE protocol.
2637 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2638 to set the channel founder authentication data. A client can
2639 claim the founder rights later by providing the authentication
2640 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2641 This way the channel founder can regain the channel founder
2642 privileges even it is left the channel. This works only on
2643 local server and the client must be connected to the same
2644 server to be able to regain the founder rights. Updated the
2645 protocol specs accordingly.
2647 Added support to the CMODE command in the client to set the
2648 founder auth data. Read the README to see how to set it.
2650 Added support to the CUMODE command to claim the founder
2651 rights. Read the README to see how to do it.
2653 Added support for the founder authentication to the Channel
2654 Entry in the server. Affected file silcd/idlist.h.
2656 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2657 server's CMODE command. Affected file silcd/command.c.
2659 * Added the following new functions into lib/silccore/silcauth.[ch]:
2660 silc_auth_get_method and silc_auth_get_data.
2662 * The server now saves the remote hosts public key to the
2663 SilcIDListData pointer. Affected file silcd/protocol.c.
2665 * The normal server now does not remove the channel entry from
2666 the cache if the founder authentication data is set. It used
2667 to remove it if the founder was the last one on the channel on
2668 the server and left the channel. The auth data is saved and
2669 if the channel is re-joined later the old entry is used with
2670 the old auth data. Affected files silcd/command_reply.c and
2673 * Removed the `pkcs' field from the SilcIDListData structure
2674 in the server; it is not used. Affected file silcd/idlist.h.
2676 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Fixed packet processing on slow links. Partial packets were
2679 never re-processed because the incoming data buffer was cleared
2680 by the application. Application must not directly clear the
2681 sock->inbuf, the packet processing routines handle it. Fixed
2682 this in client library and in server.
2684 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * Fixed the WHOIS and IDENTIFY send reply function to really
2687 check whether to send list or just one entry. Affected file
2690 * Cleaned up the LEAVE command's channel key distribution. The
2691 affected file silcd/command.c.
2693 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2694 can enforce the channel mode as well. In that case the ID
2695 includes the ID of the server. The code now enforces the
2696 mode change if the router have different mode than the server.
2698 * The notify client operation with CMODE_CHANGE notify can now
2699 return NULL client_entry pointer if the CMODE was not changed
2700 by client. Application must check for this.
2702 * Added <Server ID> argument to INFO command to support server
2703 info fetching by Server ID.
2705 * Added silc_server_announce_get_channel_users to get assembled
2706 packets of channel users of the specified channel. Affected
2707 file silcd/server.[ch].
2709 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2710 was freed underneath the ID Cache.
2712 * Re-announce clients when the server received CHANNEL_CHANGE
2713 notify from the router. Affected file silcd/packet_send.c.
2715 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2718 crashed since it did not handle the fact that there is no cipher
2719 called "3" and didn't check the error condition. Now fixed.
2721 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2722 flag. It can be used to send message requests.
2724 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Implemented the RESTART command in the client.
2728 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2729 notice type messages. Added notice printing to the user
2732 * The channel keys are not re-generated if the channel's mode
2733 is PRIVKEY, ie private key on the channel exists. Affected
2734 files silcd/server.c and silcd/command.c.
2736 * Fixed a little bug in channel message delivery when channel
2737 private keys are set in the server. Affected file is
2738 silcd/packet_send.c.
2740 * Changed the setting on channel->on_channel = TRUE from the
2741 silc_client_save_channel_key to the JOIN command reply. The
2742 key payload is not received if the private channel key is set.
2743 Affected file lib/silcclient/command_reply.c and the
2744 lib/silcclient/client_channel.c.
2746 * When the CMODE_CHANGE notify is sent and the channel private
2747 key mode is removed the channel key must be re-generated in
2748 other cells as well. Added this support for the router in the
2749 silcd/packet_receive.c.
2751 * Added new local command NOTICE to send notice message on
2752 channel. Affected file silc/local_command.[ch].
2754 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * Added new local command ME to the client. It is used to send
2757 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2758 some action. Affected file silc/local_command.[ch].
2760 * Changed channel_message and private_message client operations
2761 to deliver the message flags to the application. Added also
2762 the `flags' arguments to the silc_client_send_channel_message
2763 and silc_client_send_private_message functions. Affected file
2766 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Redefined the Private Message Payload to support private message
2769 keys and to support the new private message flags. Updated
2770 the protocol specs. Flags makes it possible to have for example
2771 CTCP style messages.
2773 * Added new type SilcPrivateMessagePayload and defined an API
2774 for it in the lib/silcclient/silcprivate.[ch].
2776 * Tested private message private keys successfully. Tested the
2777 private message key set, unset and list commands with the new
2780 * Redefined the Channel Message Payload to include the channel
2781 message flags (equal with private message flags) to support
2782 for example CTCP style messages.
2784 * Defined some of the message (for channel and private message)
2785 flags. Updated the protocol specs and added the flags to the
2786 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2788 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Added SilcKeyAgreementStatus type to the key agreement routines
2791 to indicate the current status and error if one occured.
2792 The status types are defined in the lib/silcclient/silcapi.h.
2794 * Added new local command KEY that is used to set and unset private
2795 keys for channels, set and unset private keys for private messages
2796 with remote clients and to send key agreement requests and
2797 negotiate the key agreement protocol with remote client. The
2798 key agreement is supported only to negotiate private message keys,
2799 it currently cannot be used to negotiate private keys for channels,
2800 as it is not convenient for that purpose.
2802 * Fixed a minor pending callback setting bug in the function
2803 silc_client_get_client_by_id_resolve, now the function works.
2804 Affected file lib/silcclient/idlist.c.
2806 * Added function silc_net_get_local_port to get local bound
2807 port by socket. Added to lib/silcutil/silcnet.[ch].
2809 * Added `sockets' and `sockets_count' fields to the SilcClient
2810 object. They hold the sockets of the listenning sockets in
2811 the client. Listenning sockets may be for example the key
2812 agreement server. Affected file lib/silcclient/client.[ch].
2813 Added functions the silc_client_add_socket and the
2814 silc_client_del_socket. They are exported to the application
2817 * Added ~./silc/clientkeys to support other client's public keys.
2819 * Renamed verify_server_key client operation to verify_public_key
2820 and added one argument to indicate the type of the connection
2821 (server, client etc.).
2823 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Added silc_server_connection_auth_request to handle the
2826 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2827 silcd/packet_receive.[ch].
2829 * Added silc_server_send_connection_auth_request into the
2830 silcd/packet_send.c to send the connection auth request packet.
2832 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2835 * Fixed the public key authentication in responder side in the
2836 server. The `auth_data' pointer includes the SilcPublicKey
2837 not the path to the public key. Affected file silcd/protocol.c.
2839 * Implemented the public key authentication in the initiator side
2840 in the server. Affected file silcd/protocol.c.
2842 * Removed the [RedirectClient] config section from the server
2843 configuration. Is not needed and I don't want to implement it.
2845 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Cleaned up the CMODE command in the server. It now works
2848 correctly and supports all the modes defined in the protocol.
2849 Affected file is silcd/command.c.
2851 * Added `hmac_name' field to the SilcChannelEntry in the server
2852 to hold the default HMAC of the channel. It can be set when
2853 creating the channel (with JOIN command). Affected files
2856 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2857 type to indicate the change of the current cipher and hmac
2858 on the channel. Client can safely ignore the <cipher> argument
2859 (if it chooses to do so) since the CHANNEL_KEY packet will
2860 force the channel key change anyway. The <hmac> argument is
2861 important since the client is responsible of setting the new
2862 HMAC and the hmac key into use.
2864 * Fixed the CMODE command in the client library as well.
2866 * Tested CMODE command in router environment successfully.
2868 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Show the version of the remote client (or server) when connecting
2871 to the server. It is logged to the log file. Affected file
2872 is silcd/protocol.c.
2874 * Fixed the KILLED notify handling in the client library. The
2875 client must be removed from all channels when receiving the
2878 Also, do not remove the client entry when giving the KILL
2879 command but when the KILLED notify is received.
2881 * Removed silc_idlist_find_client_by_nickname from the server.
2882 Not needed anymore. Affected files silcd/idlist.[ch].
2884 * Implemented the CHANNEL_CHANGE notify type handling to the
2885 server. Affected file silcd/server.c.
2889 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Added silc_server_send_notify_invite to send the INVITE
2892 notify between routers.
2894 * Implemented the INVITE command correctly to the server.
2896 * Implemented the INVITE notify type handling in the server.
2898 * Implemented the INVITE command to the client library and on the
2901 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Added function silc_server_get_client_resolve to find the
2904 client entry by ID from all ID lists and then resolve it
2905 (using WHOIS) if it cannot be found. Affected file is
2908 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Implemented the BAN command to the client library.
2912 * The JOIN command in the server now checks the invite list
2915 * Changed the silc_command_reply_payload_encode_va and the
2916 silc_command_payload_encode_va to support that if argument is
2917 NULL it ignores and checks the next argument. Affected file
2918 lib/silccore/silccommand.c.
2920 * Added silc_server_send_notify_ban to send the BAN notify
2921 type between routers.
2923 * Chaned the silc_notify_payload_encode to support that if
2924 argument is NULL it ignores and checks the next argument.
2925 Affected file lib/silccore/silcnotify.c.
2927 * Tested ban lists in router environment successfully.
2929 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Implemented BAN command to the server, in silcd/command.[ch].
2933 * Removed the BAN and INVITE_LIST modes from the CMODE command
2936 * Added function silc_string_match to regex match two strings.
2937 Affected files lib/silcutil/silcutil.[ch].
2939 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Redefined parts of the SilcChannelEntry in the server to support
2942 the new ban and invite lists.
2944 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Redefined the INVITE command. The same command can be used to
2947 invite individuals to the channel but also to manage the invite
2948 list of the channel (to add to and remove from the invite list).
2949 Updated the protocol specs.
2951 * Added new command SILC_COMMAND_BAN that can be used to manage
2952 the ban list of the channel. Updated the protocol specs.
2954 * Removed the channel modes: the SILC_CMODE_BAN and the
2955 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2956 in the CMODE command. The equivalent features are now available
2957 using INVITE and BAN commands. Updated the protocol specs.
2959 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2960 in the network about change in the current ban list. The notify
2961 type is not used by the client.
2963 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2964 support the invite lists.
2966 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Added new function silc_string_regexify that converts string
2969 including wildcard characters into regex string that can
2970 be used by the GNU regex library. Added into the file
2971 lib/silcutil/silcutil.[ch].
2973 Added silc_string_regex_combine to combine to regex strings
2974 into one so that they can be used as one regex string by
2975 the GNU regex library. Added into the file
2976 lib/silcutil/silcutil.[ch].
2978 Added silc_string_regex_match to match two strings. It returns
2979 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2981 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Imported GNU regex to the soruce tree into lib/contrib.
2984 Fixed some compiler warning from the regex.c.
2986 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Fixed MOTD command in the server to work in router environment.
2990 * Fixed the MOTD command in the client library to support
2991 the server argument in the command.
2993 * Added `nickname_len' argument to the silc_idlist_add_client
2994 in the server, as the `nickname' argument may be binary data
2997 * Added silc_idlist_get_channels to return all channels from
3000 * Implemented LIST command to the server. Affected file is
3003 * Implemented the LIST command to the client library and on the
3006 * Added [<user count>] argument to the LIST command reply.
3007 With private channels the user count is not shown.
3009 * Updated TODO and README.
3011 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * The client entry's data.registered must be TRUE even with
3014 global client entry on global client list. The data.registered
3015 is used to check whether the client is anymore in the network,
3016 for example with WHOWAS command so it must be valid.
3018 * Fixed the WHOWAS command in the server. It now actually works
3019 in router environment. Added function into silcd/command_reply.c
3020 silc_server_command_reply_whowas_save.
3022 * Added silc_idlist_purge function to the silcd/idlist.c
3023 to periodically purge the ID Cache.
3025 * Fixed INFO command in the server. It works now in router
3026 environment. Added <server name> argument to the INFO command
3027 reply. Updated the protocol specs.
3029 * Fixed minor bug in silc_idcache_purge to not purge if the
3030 expire value is zero.
3032 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3033 they were buggy because of the WHOWAS information.
3035 * Fixed local command MSG to handle the async resolving of
3036 the remote client properly. It used to fail the first MSG.
3037 Affected file silc/local_command.c.
3039 * Added `data_len' field to SilcIDCache context.
3041 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Update TODO. Todo in commands in the server.
3045 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3048 used by routers as broadcast packet to inform other routers
3049 about the changed user mode.
3051 Implemented the notify handling in the server. Affected file is
3052 silcd/packet_receive.c. Added the function
3053 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3055 * Added new generic Channel Payload and deprecated the New Channel
3056 Payload. The New Channel Payload is now the generic Channel
3059 * Added new argument `mode' to the silc_server_send_new_channel
3060 as it is required in the Channel Payload now.
3062 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3063 and created a new and real SilChannelPayload to represent the
3064 new generic Channel Payload. Implemented the encode/decode
3065 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3067 * Added silc_server_get_client_channel_list to return the list
3068 of channels the client has joined for WHOIS command reply.
3069 Affected file silcd/server.[ch].
3071 * Implemented the channel list sending in the WHOIS command reply
3072 in server and in the client.
3074 Implemented the channel list displaying on the user interface
3075 as well. Affected file silc/client_ops.c.
3077 * Added silc_channel_payload_parse_list to parse list of Channel
3078 Payloads. It returns SilcDList list of SilcChannelPayloads.
3079 Client for example can use this function to parse the list of
3080 channels it receives in the WHOIS command reply. The caller
3081 must free the list by calling silc_channel_payload_list_free.
3082 Affected files lib/silccore/silcchannel.[ch].
3084 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added one new argument <user mode> to the WHOIS command reply
3087 to return the mode of the user in SILC. Updated the protocol
3090 Implemented it to the server and client.
3092 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Fixed the mode printing on the user interface on joining.
3095 Affected file silc/client_ops.c.
3097 * Implemented the UMODE command and user modes in general to the
3098 client library and to the user interface.
3100 * Implemented the UMODE command to the server.
3102 * The server now sends UNKNOWN_COMMAND error status if client sends
3103 unknown command. Affected file silcd/command.c.
3105 * All server commands now handle the command identifier the right
3106 way when sending the command reply to the client. The client can
3107 use to identify the command replies with the identifier.
3109 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Added silc_server_get_client_route to resolve the route to
3112 the client indicated by the client ID. Affected file is
3115 * Added silc_server_relay_packet as general function to relay
3116 packet to arbitrary destination. This deprecates functions
3117 like _send_private_message_key, _relay_notify etc. Affected
3118 file is silcd/packet_send.[ch].
3120 Removed silc_server_send_key_agreement,
3121 silc_server_send_private_message_key and
3122 silc_server_packet_relay_notify functions from the file
3123 silcd/packet_send.[ch].
3127 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3128 server. Affected file silcd/packet_receive.[ch].
3130 * Implemented the KILL command to the client. Implemented the
3131 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3132 Affected files lib/silcclient/command[_reply].c and
3133 lib/silcclient/client_notify.c. Implemented the KILL notify
3134 printing in the user inteface.
3136 * Fixed a lot silc_parse_nick memory leaks from the client
3137 library in the file lib/silcclient/command.c.
3139 * Changed the silc_server_send_notify_on_channels's `sender'
3140 argument from SilcSocketConnection to SilcClientEntry to
3141 check the sender as entry and not as connection object and not
3142 to send to the client provided as argument. The affected file
3143 is silcd/packet_send.[ch].
3145 * The notify packets that are destined directly to the client used
3146 to not to be processed by the server. Now changed that and the
3147 server processes all notify packets. After relaying the packet
3148 to the client the notify packet is processed in the server.
3150 * The silc_server_free_client_data now checks whether there is
3151 pending outgoing traffic for the client and purges the data to
3152 the network before removing the client entry.
3154 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3157 an client is killed from the SILC Network. Updated the protocol
3160 Added new function silc_server_send_notify_killed to the
3161 silcd/packet_send.[ch].
3163 * Added function silc_server_packet_relay_notify to relay notify
3164 packets that are destined directly to a client. In this case
3165 the server does not process the notify packets but merely relays
3166 it to the client. Affected file silcd/packet_send.[ch].
3168 Added also silc_server_packet_process_relay_notify to check
3169 whereto relay the notify. Affected file is
3170 silcd/packet_receive.[ch].
3172 * Implemented the KILL command to the server.
3176 * Added the backup schema desgined last fall to the protocol
3177 specs for everyone to see. The specification is in the
3178 *-spec-xx.txt draft and the packet type definitions for the
3179 backup routers is in *-pp-xx.txt draft. Thusly, added also
3180 new packet type SILC_PACKET_CELL_ROUTERS.
3182 * A big security problem in the implementation discovered. The
3183 signoff of an client did not cause new channel key generation
3184 which it of course should've done. The channel keys must be
3185 always re-generated when client leaves (or signoffs) the channel.
3186 The silc_server_remove_from_channels funtion now handles
3187 the channel key re-generation.
3189 * Added `sender' argument to the silc_server_send_notify_on_channels
3190 to not to send the client provided as argument. Affected file
3191 silcd/packet_send.[ch].
3193 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Implemented OPER and SILCOPER commands into the server and
3198 * Added silc_auth_verify and silc_auth_verify_data to verify
3199 the authentication directly from the authentication payload.
3200 It supports verifying both passphrase and public key based
3201 authentication. Affected file lib/silccore/silcauth.[ch].
3203 * Added `hash' field to the SilcIDListData structure. It is the
3204 hash negotiated in the SKE protocol. Affected file is
3207 * Slight redesigning of the SilcAuthPayload handling routines.
3208 Do not send SilcPKCS but SilcPublicKey as argument.
3210 * Implemented the public key authentication support to the
3211 serverconfig. The public key is loaded from the provided path
3212 and saved as authentication data to void * pointer. Thus,
3213 changed the unsigned char *auth_data to void *auth_data;
3215 * Fixed SHUTDOWN command to send the reply before the server
3216 is shutdown. :) Affected file silcd/command.c.
3218 * Fixed fatal bug in CONNECT command. The hostname was invalid
3219 memory and server crashed. Affected file silcd/command.c.
3221 * Fixed fatal bug in CLOSE command. The server_entry became
3222 invalid but was referenced later in the command. Affected file
3225 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Fixed fatal bug in failure packet handling. Server ignored
3228 the failure and thus crashed when it came.
3232 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3235 that the command may be executed only once in (about) 2 seconds.
3236 The old SILC_CF_LAG flag is same but allows command bursts up
3237 to five before limiting.
3239 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3240 server code. Various commands now includes the CF_LAG_STRICT
3241 flag to disallow any kind of miss-use of the command.
3243 * Fixed the silc_buffer_unformat to not to allocate any data
3244 if the length of the data is zero. It used to allocate the
3245 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3247 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Changed the format of AdminConnection configuration section
3250 in the server. Added username of the admin to the format.
3251 Affected files silcd/serverconfig.[ch].
3253 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3254 to return admin configuration data by host, username and/or
3257 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Implemented WHOWAS command to the server. Added the functions:
3261 silc_server_command_whowas_parse,
3262 silc_server_command_whowas_send_reply,
3263 silc_server_command_whowas_from_client and
3264 silc_server_command_whowas_from_server
3266 * Added <Client ID> argument to the WHOWAS command reply. Updated
3267 the protocol specs accordingly.
3269 * Implemented WHOWAS command and command_reply to the client
3272 Implemented the WHOWAS printing on the user interface.
3274 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Added new argument to the WHOWAS command reply, the real name.
3277 It is an optional argument. Updated the protocol specs.
3279 * Added SilcIDCacheDestructor callback that is registered when
3280 the SilcIDCache is allocated. The callback is called when
3281 an cache entry in the ID Cache expires, or is purged from the
3282 cache. Added into lib/silccore/idcache.[ch].
3284 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3285 to destruct the client entries when the cache entry expires.
3286 Other ID Cache's in server and in the client library ignores
3289 * If the ID Cache entry's `expire' field is zero then the entry
3290 never expires. Added boolean `expire' argument to the
3291 silc_idcache_add function in the lib/silccore/idcache.[ch].
3292 If it is TRUE the default expiry value is used.
3294 * Added silc_server_free_client_data_timeout that is registered
3295 when client disconnects. By default for 5 minutes we preserve
3296 the client entry for history - for WHOWAS command.
3298 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Added support to the server to enforce that commands are not
3301 executed more than once in 2 seconds. If server receives
3302 commands from client more frequently, timeout is registered
3303 to process the commands. Affected file silcd/command.c.
3304 Added new function silc_server_command_process_timeout.
3306 * Changed NICK_NOTIFY handling in client library to check that
3307 if the client's nickname was changed, so there is no need to
3308 resolve anything from the server.
3310 * Removed error printing from the WHOIS and IDENTIFY commands.
3311 If error occurs then it is ignored silently in the client library.
3312 The application, however, may map the received error to
3313 human readable error string. The application currently maps
3314 the NO_SUCH_NICKNAME error to string.
3316 * Made the command status message public to the application. Moved
3317 them from lib/silcclient/command_reply.c to
3318 lib/silcclient/command_reply.h. The application can map the
3319 received command status to the string with the
3320 silc_client_command_status_message function.
3322 * Added check to the server to check that client's ID is same
3323 as the Source ID in the packet the client sent. They must
3326 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Added dist-bzip hook to the Makefile.am to make bzip2
3329 compressed distributions.
3331 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Server now enforces the maximum length for the nickname and
3334 the channel as protocol specification dictates. 128 bytes for
3335 nickname and 256 bytes for channel name.
3337 * Moved the WHOIS printing to the application. The client libary
3338 does not print out the WHOIS information anymore, the application
3339 must do it. Renamed silc_client_command_reply_whois_print to
3340 the silc_client_command_reply_whois_save.
3342 The client's idle time is also sent to the application now, and
3343 the idle is shown on screen.
3345 * Added silc_client_command_reply_identify_save to save the
3346 received IDENTIFY entries.
3348 * Do not check for channel private keys in message sending and
3349 reception if the channel does not have the PRIVKEY mode set.
3350 Affected file lib/silclient/client_channel.c.
3352 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3355 just surfaced after chaning the JOIN procedure.
3357 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added silc_client_get_clients_by_list to get client entries
3360 from Client ID list, that is returned for example by JOIN
3361 and USERS command replies. The application should use this
3362 function for example when JOIN command reply is received to
3363 resolve the clients already on the channel (library does not
3364 do that anymore as USERS command reply is not used in the JOIN
3365 procedure anymore). Affected files lib/silcclient/silcapi.h and
3366 lib/silcclient/idlist.c.
3368 * JOIN command reply and USERS command reply returns now SilcBuffer
3369 pointers instead of unsigned char pointers when returning
3370 the client list and mode list.
3372 * Added <Client ID> argument to the JOIN command reply, mainly
3373 for the server to identify for which client the command was
3374 originally sent. Updated protocol specs accordingly.
3376 * Added SilcDlist private_key pointer to the SilcChannelEntry
3377 in the client to support the channel private keys. Affected
3378 file is lib/silcclient/idlist.h.
3380 * Added SilcChannelPrivateKey argument to the function
3381 silc_client_send_channel_message so that application can choose
3382 to use specific private ke if it wants to. If it is not provided,
3383 the normal channel key is used, unless private keys are set.
3384 In this case the first (key that was added first) is used
3385 as the encryption key.
3387 * Implemented the support for channel private key handling.
3388 Implemented the following functions:
3390 silc_client_add_channel_private_key,
3391 silc_client_del_channel_private_keys,
3392 silc_client_del_channel_private_key,
3393 silc_client_list_channel_private_keys and
3394 silc_client_free_channel_private_keys
3396 Affected file lib/silcclient/client_channel.c.
3398 * Added the support for the private keys in the channel message
3399 sending and encryption and in the message reception and
3400 decryption. Affected funtions are
3401 silc_client_send_channel_message and silc_client_channel_message.
3403 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Added SKE's key verify callback to the client library's
3406 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3408 * Removed the statement that server (or router) must send USERS
3409 command reply when joining to the channel so that the client
3410 knows who are on the channel. Instead, the client list and
3411 client's mode list is now sent in the JOIN command reply to the
3412 client who joined channel. This is better solution.
3414 * Added function silc_server_get_users_on_channel and function
3415 silc_server_save_users_on_channel to the silcd/server.[ch].
3417 * Removed function silc_server_command_send_users from the
3420 * Do not show topic on the client library anymore. The topic is
3421 sent in the command reply notify to the application and the
3422 application must show the topic now.
3424 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added client searching by nickname hash into the IDENTIFY and
3427 WHOIS commands in the server as they were clearly missing from
3428 them. Affected file is silcd/command.c.
3430 * Fixed a bug in private message receiving in the client library.
3431 The remote ID was freed and it wasn't supposed, now it is
3434 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Minor fix to the channel payload; allocate the data area, as it
3437 needs to be of specific length.
3439 * If the key agreement port is zero then the operating
3440 system will define the bound port. Affected files are
3441 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3443 * Added new function silc_channel_payload_decrypt into the file
3444 lib/silccore/silcchannel.[ch].
3446 * Moved the channel message etc, check from silc_packet_decrypt
3447 to applications. The library calls now a generic
3448 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3449 when the packet is either normal or special. This was done to
3450 allow more wide range of checking that was not allowed when
3451 the code was in library. Now applications can do virtually any
3452 checks to the packet and return to the library the decision how
3453 the packet should be processed. Affected files are
3454 lib/silccore/silcpacket.[ch].
3456 Added silc_server_packet_decrypt_check to the server and
3457 silc_client_packet_decrypt_check to the client library.
3459 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3460 to send with specified source and destination information.
3462 * Channel message delivery between routers was broken after the
3463 channel key distribution was fixed earlier. The channel key
3464 was used be to distributed to other routers as well which is not
3465 allowed by the protocol. Now this is fixed and channel keys
3466 really are cell specific and the channel message delivery between
3467 routers comply with the protocol specification.
3469 * Fixed various commands in server to check also the global list
3470 for the channel entry and not just the local list. The affected
3471 file silcd/command.c.
3473 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Added assert()s to buffer formatting and unformatting routines
3476 to assert (if --enable-debug) when error occurs. Affected
3477 file: lib/silcutil/silcbuffmt.c.
3479 * Changed to auto-reconnect to check whether the remote host is
3480 router and register the re-connect timeout if it is. It used
3481 to check that whether we are normal server, but router must do
3482 auto-reconnect with another router as well. Affected file
3485 * Removed the [<key len>] option from CMODE command as the cipher
3486 name decides the key length, nowadays. See the defined ciphers
3487 from the protocol specification.
3489 * Added [<hmac>] option to the CMODE command to define the HMAC
3490 for the channel. Added SILC_CMODE_HMAC channel mode.
3492 * Added [<hmac>] option for the JOIN command so that user can
3493 select which HMAC is used to compute the MACs of the channel
3496 * Added Hmac field to the Channel Message Payload. The integrity
3497 of plaintext channel messages are now protected by computing
3498 MAC of the message and attaching the MAC to the payload. The
3499 MAC is encrypted. Now, it is clear that this causes some
3500 overhead to the size of the packet but rationale for this is that
3501 now the receiver can verify whether the channel message decrypted
3502 correctly and also when private keys are set for the channel the
3503 receiver can decrypt the packet with several keys and check from
3504 the MAC which key decrypted the message correctly.
3506 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3507 lib/silccrypt/silccipher.[ch].
3509 * Added silc_hash_len to return the digest length into the
3510 lib/silcrypt/silchash.[ch].
3512 * Rewrote parts of Silc Channel Payload interface in the
3513 lib/silccore/silcchannel.[ch]. The encode function now also
3514 encrypts the packet and parse function decrypts it.
3516 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Fixed a minor formatting bug in the SKE's key material processing.
3519 It actually might have processed the keys wrong way resulting
3522 * Redefined the mandatory HMAC algorithms and added new algorithms.
3523 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3524 and hmac-md5 truncated to 96 bits. The mandatory is now
3525 hmac-sha1-96. Rest are optional (including the one that used
3526 to be mandatory). Rationale for this is that the truncated HMAC
3527 length is sufficient from security point of view and can actually
3528 make the attack against the HMAC harder. Also, the truncated
3529 HMAC causes less overhead to the packets. See the RFC2104 for
3532 * Added new [hmac] configuration section. The SKE used to use
3533 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3534 is of course wrong. The official names that must be proposed in
3535 the SKE are the ones defined in the protocol specification
3536 (hmac-sha1-96 for example). The user can configure any hmac
3537 using any hash function configured in the [hash] section. At
3538 least, the mandatory must be configured.
3540 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3542 * Added HMAC list to the SKE proposal list. It has now both
3543 hash algorithm list and HMAC list. This makes the protocol
3544 incompatible with previous versions. The SKE now seems to work
3545 the way it is supposed to work, for the first time actually.
3547 * Defined plain Hash algorithms to the protocol specification.
3550 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Implemented support for key agreement packets into the server.
3553 Added functions silc_server_key_agreement and
3554 silc_server_send_key_agreement. Other than these functions,
3555 server has nothing to do with this packet.
3557 * Added support for private message key packets into the server.
3558 Added functions silc_server_private_message_key and
3559 silc_server_send_private_message_key.
3563 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3564 called in the protocol's final callback instead in the END
3565 protocol state. This makes a little more sense and in the same
3566 time in client we can use the same protocol routines for normal
3567 key exchange and to key agreement packet handling as well.
3569 * Added to both client's and server's KE protocol context the
3570 SilcSKEKeyMaterial pointer to save the key material. We will
3571 bring the key material to the protocol's final callback by doing
3572 this. The final callback must free the key material.
3574 * Added SKE's packet_send callback into client's KE protocol
3575 context so that the caller can choose what packet sending function
3576 is used. This way we can use different packet sending when
3577 doing normal SKE when doing key agreement packet handling (in
3578 the key agreement packet handling we do not want to encrypt
3581 * Implemented the responder side of the key agreement routines
3582 in the client. The client can now bind to specified port and
3583 accept incoming key negotiation. The key material is passed
3584 to the application after the protocol is over.
3586 * Implemented the processing of incoming Key Agreement packet
3587 in the client. Added function silc_client_key_agreement to
3590 * Implemented the intiator side of the key agreement routines
3591 in the client. The client can now initiate key agreement with
3592 another remote client. The key material is passed to the
3593 application after the protocol is over.
3595 * Created client_keyagr.c to include all the key agreement
3598 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3599 SILC_TASK_CALLBACK except that it is not static.
3601 * Created client_notify.c and moved the Notify packet handling
3602 from the client.[ch] into that file.
3604 * Created client_prvmsg.c and moved all private message and
3605 private message key routines from the client.[ch] into that file.
3607 * Create client_channel.c and moved all channel message and
3608 channel private key routines from the client.[ch] into that file.
3610 * Changed silc_client_get_client_by_id_resolve to resolve with
3611 WHOIS command instead of IDENTIFY command, in the file
3612 lib/silclient/idlist.c.
3614 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Implemented the SKE's responder side to the Client library.
3618 * When FAILURE is received to the protocol do not trust it
3619 blindly. Register a timeout to wait whether the remote closes
3620 the connection as it should do it, only after that process the
3621 actual failure. This was changed to both client and server.
3623 * Added client_internal.h to include some of the structures
3624 there instead of client.h in lib/silcclient/.
3626 * Added function silc_task_unregister_by_callback to unregister
3627 timeouts by the callback function.
3629 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Some "Incomplete WHOIS info" errors has been appearing on the
3632 log files. Took away the entry->userinfo check from WHOIS
3633 reply sending. The entry->userinfo is now " " if client did not
3634 provide one. I thought this was fixed earlier but something
3635 is wrong still. Let's see if the error still appears.
3637 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Fixed a minor bug in the login when the channel key is
3640 re-generated in the server. It used to generate the key in
3641 wrong order and thus caused problems in the channel traffic.
3643 * Fixed a minor bug in channel key distsribution after
3644 KICK command. The key was not sent to the router even though
3647 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Added silc_ske_process_key_material_data as generic routine
3650 to process any key material as the SILC protocol dictates. The
3651 function is used by the actual SKE library but can be used by
3652 applications as well. This relates to the private message keys
3653 and the channel private keys since they must be processed the
3654 same way the normal SILC session keys. The protocol dictates
3655 this. Affected files: lib/silcske/silcske.[ch].
3657 Added also silc_ske_free_key_material to free the
3658 SilcSKEKeyMaterial structure.
3660 * Defined silc_cipher_set_key function to set the key for
3661 cipher without using the object's method function. The affected
3662 files: lib/silccrypt/silccipher.[ch].
3664 * Implemented silc silc_client_add_private_message_key,
3665 silc_client_add_private_message_key_ske,
3666 silc_client_del_private_message_key,
3667 silc_client_list_private_message_keys and
3668 silc_client_free_private_message_keys functions in the
3671 Added functions silc_client_send_private_message_key to send
3672 the Private Message Key payload and silc_client_private_message_key
3673 to handle incoming Private Message Key payload.
3675 * Added Cipher field to the Private Message Key payload to set
3676 the cipher to be used. If ignored, the default cipher defined
3677 in the SILC protocol (aes-256-cbc) is used.
3679 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Removed lib/silcclient/ops.h file.
3683 Redefined parts of the SILC Client Library API. Created new
3684 file silcapi.h that deprecates the ops.h file and defines the
3685 published Client Library API. Defined also private message key
3686 API and channel private key API into the file.
3688 This is the file that the application must include from the
3689 SILC Client Library. Other files need not be included by
3690 the application anymore.
3692 * Added new key_agreement client operation callback and also
3693 defined the Key Agreement library API for the application.
3695 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3698 is used by clients to request key negotiation between another
3699 client in the SILC network. If the negotiation is started it
3700 is performed using the SKE protocol. The result of the
3701 negotiation, the secret key material, can be used for example
3702 as private message key.
3704 Implemented the Key Agreement payload into the files
3705 lib/silccore/silauth.[ch].
3707 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Redefined ciphers for the SILC protocol. Added some new ciphers
3710 and defined the key lengths for the algorithms. Changed the
3711 code accordingly. The default key length is now 256 bits.
3713 * Fixed SKE key distribution function silc_ske_process_key_material
3714 when the key length is more than 128 bits. The default key
3715 length in SILC is now 256 bits.
3717 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3718 to indicate unsupported algorithm.
3720 * Renamed rijndael.c to aes.c and all functions as well.
3722 * Fixed a long standing channel key setting bug in client library.
3723 Weird that it has never surfaced before.
3725 * Fixed bug in channel deletion. If the entire channel is removed
3726 then it must also delete the references of the channel entry
3727 from the client's channel list as the client's channel entry and
3728 the channel's client entry share same memory.
3730 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Implemented CONNECT and SHUTDOWN commands in the client.
3734 * Implemented CLOSE command to the client.
3736 * Added the function silc_idlist_find_server_by_name into the
3737 files silcd/idlist.[ch].
3739 Added the function silc_idlist_find_server_by_conn into the
3740 files silcd/idlist.[ch].
3742 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * DIE command was renamed to SHUTDOWN. Updated the both code
3747 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3748 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3750 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3753 * Added function silc_server_create_connection function to create
3754 connection to remote router. My server implementation actually
3755 does not allow router to connect to normal server (it expects
3756 that normal server always initiates the connection to the router)
3757 so the CONNECT command is only good for connecting to another
3760 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3763 or some other client was kicked from the channel.
3765 Implemented the handling of the notify type to both client
3768 Implemented silc_server_send_notify_kicked to send the KICKED
3769 notify. It is used to send it to the server's primary router.
3771 * Implemented the KICK command into server and client.
3773 * Added `query' argument to the silc_idlist_get_client function
3774 to indicate whether to query the client from server or not if
3777 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3778 to indicate that the client is not channel founder.
3782 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Removed the rng context from SilcPacketContext structure and
3785 changed that the packet routine uses the Global RNG API.
3787 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added support for quit message that client can "leave" on the
3790 channel when it quits the SILC. It is ditributed inside the
3791 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3793 Added silc_server_free_client_data that will take the
3794 signoff message as argument.
3796 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3798 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Updated parts of the protocol specification to keep it up
3803 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3806 payloads in one packet.
3808 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3809 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3810 use now the new List flag.
3812 * Also deprecated the following packet types: REPLACE_ID,
3813 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3815 * Added list support for Notify packet in server.
3817 * Added silc_server_send_notify_channel_change to send the
3818 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3819 the silc_server_send_replace_id.
3821 * Added silc_server_send_notify_nick_change to send the
3822 NICK_CHANGE notify type. Deprecates the function
3823 silc_server_send_replace_id.
3825 * Added silc_server_send_notify_join to send the JOIN notify type.
3826 Deprecates the function silc_server_send_new_channel_user.
3828 * Added silc_server_send_notify_leave to send LEAVE notify type.
3829 Deprecates the function silc_server_send_remove_channel_user.
3831 * Added silc_server_send_notify_cmode and
3832 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3833 types. Deprecates the silc_server_send_set_mode function.
3835 * Added SERVER_SIGNOFF notify type to indicate that server has
3836 quit. This means that all clients on the channel from that
3837 server will drop. This can be also used when netsplit happens.
3839 Deprecated REMOVE_ID packet type since it is not needed anymore
3842 Added silc_server_send_notify_server_signoff to send the
3843 SERVER_SIGNOFF notify type. Deprecates the function
3844 silc_server_send_remove_id.
3846 Added also silc_server_send_notify_signoff to send the
3847 SIGNOFF notify type.
3849 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3850 SILC protocol from this day on. Changed the protocol
3851 specification as well.
3853 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3854 notify type. It is used between routers to notify about
3855 topic changes on a channel.
3857 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3860 * Partly updated the protocol specification to comply with the
3861 changes now made. It is still though a bit outdated.
3863 * The JOIN notify type now takes one extra argument <Channel ID>.
3864 The packet used to be destined to the channel but now the
3865 JOIN type may be sent as list thus it is impossible to
3866 destine it to any specific channel. By adding this argument
3867 it is again possible.
3869 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Added CREDITS file. The CHANGES and CREDITS file will appear
3872 in the distribution as well.
3874 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3877 types in the server's silcd/packet_receive.c.
3879 * Implemented CMODE and CUMODE to work in router environment.
3881 * Fixed minor encoding and decoding buglet from the
3882 lib/silccore/silcmode.c.
3884 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3887 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3889 * Changed all SilcConfigServer* and silc_config_server* to
3890 SilcServerConfig* and silc_server_config*, respectively.
3893 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Associated the ID (client or server ID) to the Authentication
3896 Payload to avoid any possibility of forging. Updated the
3897 protocol specification and the code accordingly.
3899 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * The RSA key length is now save to the RsaKey context in the
3902 key generation process in lib/silccrypt/rsa.c. The key length
3903 is now used to figure out the maximum size of the block allowed
3904 to be encrypted/signed.
3906 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3907 is equivalent to the silc_mp_mp2bin but does not allocate any
3910 * Changed silc_mp_mp2bin API to take length argument. If it is
3911 non-zero then the buffer is allocated that large. If zero, then
3912 the size is approximated using silc_mp_sizeinbase, which however
3915 * Created Global RNG API which is global RNG that application can
3916 initialize. After initializing, any routine anywhere in the
3917 code (including library) can use RNG without allocating a new
3918 RNG object. This was done to allow this sort of use of the
3919 RNG in code that has no chance to allocate RNG object. All
3920 applications currently allocate this and many routines in the
3921 library use this. Affected file lib/silccrypt/silcrng.[ch].
3923 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3924 it to use the Global RNG API.
3926 * Defined Authentication Payload into protocol specification that
3927 is used during SILC session to authenticate entities. It is
3928 used for example by client to authenticate itself to the server
3929 to obtain server operator privileges.
3931 Implemented this payload into the lib/silccore/silcauth.[ch].
3932 Implemented also routines for public key based authentication
3933 as the new protocol specification dictates.
3935 Moved definitions of different authentication methods from
3936 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3938 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3939 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3940 silc_pkcs_verify_with_hash functions into the file
3941 lib/silccrypt/silcpkcs.[ch].
3943 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * The client entry's userinfo pointer must be always valid.
3946 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3947 will fail since it requires the userinfo. Now, the userinfo
3948 is allocated as "" if actual userinfo does not exist. Actually,
3949 it must exist and it is totally Ok to drop client connections
3950 that does not announce the userinfo. However, we will make
3951 this workaround for now.
3953 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3954 to return the remote port by socket.
3956 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3959 SILC_SERVER_PENDING_EXEC and added an new macro
3960 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3961 data or when error occurs while processing the pending command.
3963 Added new argument `destructor' into silc_server_command_pending
3964 and to the SilcServerCommandPending object. This destructor is
3965 now called after calling the pending callback or if error occurs
3966 immediately. If error occurs the actual pending callback won't
3967 be called at all - only the destructor. The destructor may be
3968 NULL if destructor is not needed.
3970 All this applies for client library code as well. Similar
3971 changes were made there as well for the pending commands.
3973 In the client, the application must now allocate the
3974 SilcClientCommandContext with the silc_client_command_alloc
3977 * Added reference counter to the SilcServerCommandContext. Added
3978 function silc_server_command_alloc and silc_server_command_dup
3981 Same type of functions added to the client library for the same
3984 * Removed the cmd_ident from IDListData away since it is now
3985 global for all connections. It is the command identifier used
3986 in command sending and with pending commands. The affected file
3989 * Added reference counter to the SilcSocketConnection objecet to
3990 indicate the usage count of the object. The object won't be
3991 freed untill the reference counter hits zero. Currently only
3992 server uses this, and client ignores it. The client must be
3993 set to use this too later. The affected files are
3994 lib/silccore/silcsockconn.[ch]. Added also the function
3995 silc_socket_dup to increase the reference counter.
3997 This was mainly added because it is possible that the socket
3998 is removed underneath of pending command or other async
3999 operation. Now it won't be free'd and proper DISCONNECTING
4000 flags, etc. can be set to avoid sending data to connection that
4001 is not valid anymore.
4003 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4004 the connection. After that it sets SILC_SET_DISCONNECTED.
4005 It is, however, possible that the socket data is not still freed.
4006 The silc_server_packet_process now checks that data is not
4007 read or written to connection that is DISCONNECTED. The socket
4008 get's freed when the reference counter hits zero.
4010 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Changed the client operation API: channel_message operation's
4013 `sender' is now the client entry of the sender, not the nickname
4014 and the `channel' is the channel entry, not the channel name.
4016 In the private_message operation the `sender' is now also the
4017 client entry of the sender not the nickname.
4019 Affected file is lib/silcclient/ops.h and all applications
4020 using the client operations.
4022 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Moved the calling of ops->connect() from connect_to_server_final
4025 into receive_new_id functin since that is the point when the
4026 client is actually allowed to send traffic to network. The
4027 affected file is lib/silcclient/client.c.
4029 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4032 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4033 (if needs broadcasting) instead of broadcasting the packets one
4034 by one which would make a burst in the network traffic.
4036 * Added `broadcast' argument to the functions in silcd/server.[ch]
4037 silc_server_create_new_channel[_with_id] to indicate whether
4038 to send New Channel packet to primary router.
4040 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added new function into the silcd/server.[ch] files:
4043 silc_server_create_new_channel_with_id to create new channel with
4044 already existing Channel ID.
4046 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4047 lib/silccore/silcpacket.h. This packet is used t send list of
4048 Set Mode payloads inside one packet. Server uses this to set
4049 the modes for the channels and clients on those channels, that it
4050 announced to the router when it connected to it. The protocol
4051 specification has been updated accordingly.
4053 * The silc_server_new_channel did not handle the packet coming
4054 from normal server as it normally does not send that. However,
4055 when it announces its channels it does send it. Implemented
4056 the support for that.
4058 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4059 into the file lib/silccore/id.h.
4061 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Fixed memory leaks in the functions silc_idlist_del_client,
4064 silc_idlist_del_channel and silc_idlist_del_server in the file
4065 silcd/idlist.c. All of those leaked like a sieve.
4067 * Fixed some small memory leaks in the client's function
4068 silc_client_notify_by_server.
4070 * Added functions into silcd/server.c: silc_server_announce_clients,
4071 silc_server_announce_channels and silc_server_announce_server.
4072 These functions are used by normal and router server to announce
4073 to its primary router about clients, channels and servers (when
4074 router) that we own. This is done after we've connected to the
4077 These functions effectively implements the following packet types:
4078 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4079 and SILC_PACKET_NEW_ID_LIST.
4081 * Added new functions into the silcd/packet_receive.[ch]:
4082 silc_server_new_id_list, silc_server_new_channel_list and
4083 silc_server_new_channel_user_list to handle the incoming
4084 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4086 * Added support of changing Channel ID in the function
4087 silc_server_replace_id. If the server that announces a channel
4088 to the router already exists in the router (with same name but
4089 with different Channel ID), router is responsible to send
4090 Replace ID packet to the server and force the server to change
4091 the Channel ID to the one router has.
4093 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4094 client that the Channel ID has been changed by the router. The
4095 normal server sends this to the client. Client must start using
4096 the new Channel ID as the channel's ID.
4098 Implemented handling of this new type into lib/silcclient/client.c
4099 into the function silc_client_notify_by_server.
4101 * Added new function silc_idlist_replace_channel_id into the files
4102 silcd/idlist.[ch] to replace the Channel ID.
4104 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Call silc_server_command_identify_check always when processing
4107 the IDENTIFY command in silcd/command.c
4109 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4112 send keepalive packets. The packet can be sent by clients,
4113 servers and routers.
4115 Added function silc_socket_set_heartbeat into the file
4116 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4117 If not set, the heartbeat is not performed. The actual
4118 heartbeat is implemented in the low level socket connection
4119 library. However, application is responsible of actually
4122 Added silc_server_send_heartbeat to send the actual heartbeat
4123 packet into silcd/packet_send.[ch]. Server now performs
4124 keepalive with all connections.
4126 * Added silc_task_get_first function into lib/silcutil/silctask.c
4127 to return the timeout task with shortest timeout. There was a bug
4128 in task unregistration that caused problems. TODO has been
4129 updated to include that task system must be rewritten.
4131 * The client library will now resolve the client information when
4132 receiving JOIN notify from server for client that we know but
4133 have incomplete information.
4135 * Rewrote parts of silc_server_remove_from_channels and
4136 silc_server_remove_from_one_channel as they did not remove the
4137 channel in some circumstances even though they should've.
4139 * Encryption problem encountered in server:
4141 The LEAVE command used to send the Channel Key packet to the
4142 router immediately after generating it. However, the code
4143 had earlier sent Remove Channel user packet but not immediately,
4144 ie. it was put to queue. The order of packets in the router
4145 was that Channel Key packet was first and Remove Channel User
4146 packet was second, even though they were encrypted in the
4147 reverse order. For this reason, MAC check failed. Now, this
4148 is fixed by not sending the Channel Key packet immediately but
4149 putting it to queue. However, this is more fundamental problem:
4150 packets that are in queue should actually not be encrypted
4151 because packets that are sent immediately gets encrypted
4152 actually with wrong IV (and thus MAC check fails). So, packets
4153 that are in queue should be encrypted when they are sent to
4154 the wire and not when they put to the queue.
4156 However, the problem is that the current system has not been
4157 designed to work that way. Instead, the packet is encrypted
4158 as soon as possible and left to the queue. The queue is then
4159 just purged into wire. There won't be any fixes for this
4160 any time soon. So, the current semantic for packet sending
4163 o If you send packet to remote host and do not force the send
4164 (the packet will be in queue) then all subsequent packets to the
4165 same remote host must also be put to the queue. Only after the
4166 queue has been purged is it safe again to force the packet
4169 o If you send all packets immediately then it safe to send
4170 any of subsequent packets through the queue, however, after
4171 the first packet is put to queue then any subsequent packets
4172 must also be put to the queue.
4174 Follow these rules and everything works fine.
4176 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Added new function silc_server_remove_clients_by_server to
4179 remove all client entries from ID list when the server connection
4180 is lost. In this case it is also important to invalidate all
4181 client entires as they hold the invalid server entry. This
4182 fixes fatal bug when server has lost connection and will reconnect
4185 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Made some sanity checks to silc_server_daemonise like to check
4188 whether the requested user and group actually exists.
4190 * Added sanity check to SKE's silc_ske_responder_finish to check
4191 that the public and private key actually is valid.
4193 * Invalidate the client's nickname when receiving Replace ID
4194 packet and the Client ID is being replaced. This means that the
4195 server will query the nickname if someone needs it (client)
4198 * Sort the ID Cache in client library when the ID Cache data
4199 has changed (needs sorting).
4201 * Do not allow for SILC client to create several connections to
4202 several servers. The client does not support windows right now
4203 and generating multiple connections causes weird behaviour.
4205 Irssi-silc client does support windows and can handle several
4206 connections without problems, see: www.irssi.org and SILC plugin.
4208 * Fixed some places where client was added to the IDList. The
4209 rule of thumb is following (in order to get everything right):
4210 If the client is directly connected local client then the
4211 `connection' argument must be set and `router' argument must be
4212 NULL to silc_idlist_add_client function. If the client is not
4213 directly connected client then the `router' argument must
4214 bet set and the `connection' argument must be NULL to the
4215 silc_idlist_add_client function.
4217 * The funtion silc_server_packet_send_local_channel actually did
4218 not check whether the client was locally connected or not. It
4219 does that now. Fixed a bug related to LEAVE command.
4221 * Fixed Remove Channel User payload parsing bug in server's
4222 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4224 * The server's silc_server_save_channel_key now checks also the
4225 global ID list for the channel as it might not be in the local
4226 list. Fixed a bug related to LEAVE command.
4228 * Is this the end of the [<unknown>] buglet that has been lurking
4229 around for a long time? A little for loop fix in server's
4230 silc_server_command_whois_parse that is used by both IDENTIFY
4231 and WHOIS command. At least, this was a clear bug and a cause
4232 of one type of [<unknown>] buglet.
4234 * WHOIS and IDENTIFY commands call the function
4235 silc_server_command_[whois/identify]_check function even if
4236 we are not router server.
4238 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Added --with-gmp configuration option. If set the GMP
4241 is always compiled in the SILC source tree. If not set then
4242 it is checked whether the system has the GMP3 installed. If
4243 it has then the GMP won't be compiled (the system's headers
4244 and library is used), if it doesn't have it then the GMP is
4245 compiled in the SILC source tree.
4247 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Changed RSA private exponent generation to what PKCS #1
4250 suggests. We try to find the smallest possible d by doing
4251 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4252 not security fix but optimization.
4254 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added new config entry [Identity] to fork the server and run
4257 it as specific user and group. A patch from Bostik.
4259 * Imported Dotconf configuration library into lib/dotconf.
4260 This will be used to create the SILC configuration files later.
4261 It will appear in the distsribution after this commit.
4263 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * A big code auditing weekend happening. Auditing code for
4266 obvious mistakes, bugs and errors. Also, removing any code
4269 Removed files for being obsolete:
4271 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4272 inline in the file lib/silcutil/silcbuffer.h)
4274 o lib/silcutil/silcbufutil.c (the header has inline versions)
4276 Changed code to fix possible error conditions:
4278 o The buffer formatting routines now check that the destination
4279 buffer really has enough space to add the data. This applies for
4280 both buffer formatting and unformatting
4281 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4282 unformatting was changed to accomodate following rules:
4283 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4284 sent to the function while XXX_*STRING will not allocate or copy
4285 the data into the buffer. Instead it sets the pointer from the
4286 buffer into the pointer sent as argument (XXX_*STRING used to
4287 require that the pointer must be allocated already). This change
4288 makes this whole thing a bit more consistent and more optimized
4289 (note that the data returned in the unformatting with XXX_*STRING
4290 must not be freed now). The routines return now -1 on error.
4292 o Tried to find all code that use buffer_format and buffer_unformat
4293 and added return value checking to prevent formatting and
4294 especially unformatting errors and possible subsequent fatal
4297 o Changed ske->x and ske->KEY to mallocated pointers in
4298 lib/silcske/silcske.h. Fixed possible data and memory leak.
4300 o Added return value checking to all *_parse* functions. Fixed
4301 many memory leaks as well.
4303 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4304 so that buffer overflows would not happen. All code now also
4305 checks the return value as it can fail.
4307 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added reconnection support to server if the normal server looses
4310 its connection to the router (for example if router is rebooted).
4311 The server performs normal reconnection strategy implemented
4312 to the server. Affected file silcd/server.c.
4314 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Added new packet type SILC_PACKET_SET_MODE that is used to
4317 distribute the information about changed modes (for clients,
4318 channels and clients channel modes) to all routers in the
4319 network. Updated the protocol specification accordingly.
4321 Added functions into silcd/packet_send.c and
4322 silcd/packet_receive.c: silc_server_send_set_mode,
4323 silc_server_set_mode.
4325 Added new files silcmode.[ch] into lib/silccore that implements
4326 the encoding and decoding of Set Mode Payload. Added new type
4327 SilcSetModePayload. Moved the definitions of different modes
4328 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4330 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Oops, a little mistake in server's connection authentication
4333 protocol. The protocol is not ended with FAILURE but with
4334 SUCCESS if the authentication is Ok. :) Affected file is
4337 * Implemented NICK_CHANGE notify handling in server in the file
4338 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4339 the local clients on the channel. After the changing nickname
4340 in router environment snhould work and the [<unknown>] nickname
4341 should appear no more.
4343 The silc_server_replace_id function that receives the Replace ID
4344 payload now sends the NICK_CHANGE notify type also in the file
4345 silcd/packet_receive.c
4347 * Changed WHOIS and IDENTIFY command to support the maximum amount
4348 of arguments defined in protocol specs (3328 arguments). This
4349 fixed a bug that caused problems when there were more than three
4352 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Added extra parameter, command identifier, to the
4355 silc_client_send_command so that explicit command identifier
4358 Changed that ID list routines uses specific command identifier
4359 when sending WHOIS/IDENTIFY requests to the server so that they
4360 can be identified when the reply comes back.
4362 Affected files lib/silcclient/command.[ch],
4363 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4365 * Added `sender' argument to silc_server_packet_send_to_channel
4366 to indicaet the sender who originally sent the packet to us
4367 that we are now re-sending. Ignored if NULL. Affected file
4368 silcd/packet_send.[ch].
4370 * Added some server statistics support in silcd/server_internal.h
4371 SilcServerStatistics structure and around the server code. Also
4372 send some nice statistics information when client is connecting
4375 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Fixed channel ID decoding in server's JOIN command reply in
4378 silcd/command_reply.c
4380 * Fixed braodcasting of replace ID payload to not to send it if
4381 we are standalone server in silcd/packet_receive.c.
4383 * Fixed all channel message sending routines to not to send
4384 packets to clients that has router set, since they are routed
4385 separately in the same function earlier. Affects file
4386 silcd/packet_send.c and all channel packet sending functions.
4388 * In USERS reply, res_argv[i] are not allocated, the table
4389 is allocated. Thus changed that free the table, not its
4392 * In server's whois_check and identify_check if the client is
4393 locally connected do not send any WHOIS commands - they are not
4396 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Fixed some minor bugs in client when sending WHOIS command. The
4399 arguments was in wrong order.
4401 * Removed statis function add_to_channel from server in
4402 silcd/command.c that was previously used with the joining but
4405 * Tested USERS command in router environment successfully with two
4406 routers, two servers and two clients.
4408 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Reorganized the USERS command and command reply in client library
4411 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4412 When the command is given by user we register a pending command
4413 callback that will reprocess the command after the reply has been
4414 received from the server. When reprocessing the packet we then
4415 display the information. Thus, the USERS information is displayed
4416 now in the command callback instead of in the command reply
4417 callback. The processing of the command is same as previously
4418 when server has sent the command reply in the JOINing process.
4420 * Added to USERS command in silcd/command_reply.c to join the client,
4421 we didn't use to know about, to the channel after we've created
4422 a client entry for it. Also, for clienet we did know already still
4423 check whether it is on the channel or not and add it if not.
4425 * Removed silc_server_command_join_notify as the function and its
4428 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Changed the client's pending command handling to the same as the
4431 server's pending command handling. It is also now possible to
4432 execute command reply functions from other command reply
4433 function as the function callbacks for commands and command
4434 replies are one and same. The pending commands are not static
4435 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4436 in client connection context. Thus, pending commands are server
4437 connection specific as it is convenient.
4439 Changed the function silc_client_command_pending and
4440 silc_client_command_pending_del and added new function
4441 silc_client_command_pending_check. Removed the
4442 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4445 * Added cmd_ident, current command identifier, to the client
4446 connection context in lib/silcclient/client.h to keep track on
4447 command identifiers used in command sending. Client's command reply
4448 function handling now supports the mandatory command identifiers.
4450 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4451 funtions in client to fully support pending command callbacks.
4453 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4454 as one of the arguments to the application in the command reply
4457 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4458 before first releasing SILC but came back. Now it is removed again
4459 and should come back nomore. The FORWARDED flag was used only
4460 by the JOINing procedure by forwarding the command packet to router.
4461 Now, the JOINing procedure has been changed to more generic (due
4462 to various router environment issues) and FORWARDED is not needed
4463 anymore for anything. The protocol specification is yet to be
4466 Now, removed silc_server_packet_forward from server and the flag
4467 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4469 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Renamed NAMES command to USERS command. The NAMES was named that
4472 due to historical reasons. Now it is renamed. Also, rewrote
4473 parts of the USERS command. The nickname list is not sent anymore
4474 by the server. Only Client ID and mode lists are sent in the USERS
4475 command. Changed this also to the protocol specification.
4477 The client now resolves the names and stuff after it receives
4478 the USERS list from the server when joining to the channel.
4480 * WHOIS and IDENTIFY commands has been changed to support multiple
4481 Client ID's per command. One can now search for multiple users
4482 in the network by sending only one WHOIS or IDENTIFY command.
4483 Changed the code and the protocol specifications.
4485 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4486 uses silc_server_command_whois_parse to parse the request. */
4488 * If normal server, do not parse the WHOIS and IDENTIFY requests
4489 before sending it to the router. Saves some time.
4491 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Fixed JOIN command on client library. Wrong number of arguments
4494 used to crash the client.
4496 * Added silc_server_channel_has_global function to check whether
4497 channel has global users or not.
4499 * Added silc_server_channel_has_local function to check whether channel
4500 has locally connected clients on the channel.
4502 * The silc_server_remove_from_one_channel now checks whether the
4503 channel has global users or not after given client was removed from
4504 the channel. It also checks whether the channel has local clients
4505 on the channel anymore. If it does not have then the channel entry
4506 is removed as it is not needed anymore.
4508 * The silc_server_notify now checks on JOIN notify whether the joining
4509 client is one of locally connected or global. If it is global then
4510 the channel has now global users on the channel and that is marked
4511 to the channel entry. Also, it now saves the global client to
4512 global list who is joining and JOINs it to the channel. This is
4513 for normal server, that is.
4515 Changed silc_server_send_notify_on_channel,
4516 silc_server_packet_relay_to_channel and
4517 silc_server_packet_send_to_channel check if we are normal server
4518 and client has router set (ie. global client) do not send the
4519 message to that client, as it is already routed to our router.
4521 * Implemented LEAVE notify type handling in silc_server_notify
4524 * Tested LEAVE command in router environment successfully. Tested
4525 with two routers, two servers and two clients.
4529 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4531 * Implemented SIGNOFF notify type handling in silc_server_notify
4534 * silc_server_remove_id now removes the client entry from all channels
4535 it has joined and thusly sends SIGNOFF notify type.
4537 * Rewrote the NAMES list generation in server by removing two excess
4538 loops. The lists are created now inside one loop.
4540 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * silc_server_remove_channel_user checks now also global list
4543 for channel and client.
4545 * silc_server_new_channel_user checks now both local and global
4546 list for channel and client. Fixed a bug in client id decoding.
4547 Used to decode wrong buffer.
4549 * silc_server_channel_message checks now both local and global
4550 list for channel entry.
4552 * Tested channel joining (hence JOIN) in router environment
4553 successfully. Tested with two routers, two servers and two
4556 * Tested channel message sending in router environment successfully.
4558 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Added silc_server_save_channel_key into server.[ch] to save the
4561 received channel key in Channel Key payload processing. It is
4562 also used in JOIN command reply handling.
4564 Equivalent function silc_client_save_channel_key added into
4565 client.[ch] into client library.
4567 * Changed JOIN command reply to send information whether the channel
4568 was created or not (is existing already) and the channel key
4569 payload. Changed protocol specs accordingly.
4571 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4572 the request was sent by ID and not by nickname. Crashed on
4575 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4578 now correctly save the received data.
4580 * silc_server_free_sock_user_data now notifies routers in the
4581 network about entities leaving the network.
4583 At the same time implemented functions silc_server_remove_id
4584 and silc_server_send_remove_id to receive and send REMOVE_ID
4585 packets. The packet is used to notify routers in the network
4586 about leaving entities. The ID removed will become invalid in
4589 * Added function silc_idlist_del_server into server. Removes and
4590 free's server entry from ID list.
4592 * silc_server_private_message function now checks, if we are router,
4593 that the destination ID really is valid ID, naturally.
4595 * In router when NEW_ID packet is received (for new client) the
4596 hash of the Client ID is saved in the ID Cache but the
4597 client->nickname is set to NULL, instead of putting the hash
4600 IDENTIFY command now also checks that client->nickname must be
4601 valid. If it is not if will request the data from the server who
4602 owns the client. Added new function
4603 silc_server_command_identify_check.
4605 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4606 to set the command to already allocated Command Payload.
4608 * Tested private message sending in router environment with two
4609 routers, two servers and two clients. Fixed minor bugs and now
4612 * Fixed segfault from client's NAMES command. Used to crash if
4615 * Forwarded packets must not be routed even if it is not destined
4616 to the receiver. Changed server code comply with this.
4618 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Added `require_reverse_mapping' boolean value to ServerParams
4621 structure. If TRUE (not default) the server will require that
4622 the connecting host has fully qualified domain name.
4624 If the reverse mapping is not required and hostname could not be
4625 found the IP address is used as hostname.
4627 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Implemented version string checking to both client and server.
4630 The check is incomplete currently due to the abnormal version
4631 strings used in development version of SILC.
4633 * Changed all command functions in server to use the new
4636 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Changed char *data to unsigned char *data in ID Cache system to
4639 support binary data as ID Cache data. Changed code to support
4640 binary data in lib/silccore/idcache.c.
4642 * Renamed silc_server_packet_relay_command_reply to
4643 silc_server_command_reply as it is normal packet receiving
4644 function. Rewrote the function to accept command replys for
4645 servers and not only for clients.
4647 * Mark remote router always as registered server if we are connecting
4648 to it. Otherwise, commands sent by the router to us are ignored.
4650 * All ID List find routines now returns the ID Cache Entry pointer
4651 as well if requested.
4653 * WHOIS command works now in router environment, tested with two
4654 routers, two servers and two clients.
4656 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4657 in router environment (as it is almost equivalent to WHOIS) but
4658 hasn't been tested thoroughly. Added new functions:
4660 silc_server_command_identify_parse
4661 silc_server_command_identify_send_reply
4662 silc_server_command_identify_from_client
4663 silc_server_command_identify_from_server
4665 * Disabled route cache adding because adding two different ID's with
4666 same IP replaces the old cache entry thus giving wrong route.
4667 The entry->router->connection is always the fastest route anyway
4668 so route cache may not be needed. Of course, new routes maybe
4669 established after receiving the ID when the entry->router->connection
4670 might not be anymore the most optimal.
4672 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Add route cache for received ID for fast routing.
4676 * Added silc_server_packet_route to route received packet on router
4677 that is not destined to us.
4679 * Renamed silc_server_get_route to silc_server_route_get.
4681 * Added id_string and id_string_len fields into SilcServer to
4682 include encoded ServerID for fast comparing without excess
4683 encoding of the ID's.
4685 * Cleaned up WHOIS command on server side. Added following static
4688 silc_server_command_whois_parse
4689 silc_server_command_whois_check
4690 silc_server_command_whois_send_reply
4691 silc_server_command_whois_from_client
4692 silc_server_command_whois_from_server
4694 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4695 arguments in command replies. All command functions should be
4696 updated to use this macro.
4698 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Minor typo fixes on command reply handling on server.
4702 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Added silc_server_command_add_to_channel internal routine to add
4705 the client to the channel after router has created the channel and
4706 sent command reply to the server.
4708 * Added generic silc_server_send_command to send any command from
4711 * Use static buffer with ID rendering instead of duplicating data.
4713 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Fixed a channel user mode bug when joining to a channel server gave
4716 everybody channel founder rights, oops.
4718 * We mark ourselves as the router of the incoming server connection
4719 if we are router ourselves. This way we can check in some packet
4720 sending functions whether it is locally connected server. For
4721 incoming router connections we put NULL.
4723 * For router sending packets locally means now always sending the
4724 packet cell wide; to local clients and local servers. For normal
4725 server sending packet locally means sending it to only local
4728 * Fixed the JOIN command to really work in router environment. If the
4729 channel is created it is always created by the router. Router is
4730 also responsible of making the initial joining to the channel,
4731 sending JOIN notify to the sending server and distributing
4732 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4733 does not exist server doesn't do anything else but forward the
4734 command to the router which performs everything.
4736 * Added silc_server_send_channel_key function to send the Channel Key
4739 * Added silc_server_create_channel_key to create new channel key. The
4740 channel key is now re-generated everytime someone joins or leaves
4741 a channel, as protocol dictates. Note: channel->key_len is the
4744 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4747 packet_receive.[ch] to separate packet sending and receiving
4748 routines. The server.[ch] now includes everything else including
4749 actual packet processing (writing and reading data) and other
4752 Renamed silc_server_private_message_send_internal to
4753 silc_server_send_private_message. The routine is still though
4754 used only to relay private messages as server does not send
4755 private messages itself.
4757 Renamed silc_server_new_channel to silc_server_create_new_channel
4758 and added new function sicl_server_new_channel that handles the
4759 incoming New Channel packet. Added also new sending function
4760 silc_server_send_new_channel to send New Channel Payload.
4762 * Added new function silc_server_notify to process incoming notify
4763 packet to the server/router. Server may then relay the notify
4764 to clients if needed.
4766 * Added new function silc_server_new_channel_user to process incoming
4767 New Channel User packet. Router will redistribute the packet and
4768 send JOIN notify to its local clients and locally connected servers
4769 if needed. Normal server will send JOIN notify to its local client
4770 on same channel when received this packet. Added also corresponding
4771 sending function silc_server_send_new_channel_user to sent the
4774 * Added boolean route argument to send_notif_to_channel and
4775 packet_send_to_channel functions to attempt to route the packet
4776 if it is TRUE and send only locally if it is FALSE.
4778 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * silc_server_replace_id now broadcasts the received replace ID
4781 packet if it is not broadcast packet already. The router must
4782 broadcast to inform other routers about changed ID.
4784 * Added backpointer to server's router into SilcServer context in
4785 silcd/server_internal.h.
4787 * Fixed silc_server_packet_broadcast to send correct broadcast
4790 * The channel key is now distributed to the local client as soon
4791 as it is received from the router (in router environment) so that
4792 no other packet may be sent for the channel until client has
4795 * silc_server_remove_channel_user now broadcasts the received
4796 Remove Channel User packet if it is not broadcast packet already.
4797 The router must broadcast to inform other routers about removed
4800 * Added users field into SilcPacketContext that is a reference count
4801 of the context. One can increase the reference count by calling
4802 silc_packet_context_dup which is now changed to just increase the
4803 reference count instead of duplicating the data. The reference
4804 count is decresed by calling silc_packet_context_free that will
4805 free the data after the reference count hits zero.
4807 For now on the packet context and everything allocated into it
4808 (including the raw packet from network) must be freed by calling
4809 the new silc_packet_context_free function. Added also new function
4810 silc_packet_context_alloc that must be used now to allocate the
4811 context. This also means that if a routine is asynchronous from
4812 silc_[client/server]_packet_parse_type the packet context must
4813 be duplicated by calling silc_packet_context_dup. Otherwise it
4814 gets free'd after silc_[client/server]_packet_parse_type returns.
4815 Also, one must remember that if packet is duplicated then its
4816 reference count must be decresed by calling the free function as
4817 many times as it was duplicated.
4819 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4820 from both client and server.
4822 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Made joining to a channel working in router environment.
4826 * Cleaned up JOIN command on server side and create function
4827 silc_server_command_join_channel internal routine to make the
4830 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Changed silc_command_pending list to SilcDList. Also, added
4833 `ident' field to SilcServerCommandPending structure to identify
4834 the reply and to call correct callback.
4836 Added silc_server_command_pending_check function to replace the
4837 corresnponding macro. The silc_command_pending list is not
4840 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4841 to set identifier to previously allocated Command Payload. It
4842 is used to set identifier for command when resending Command
4845 * Added silc_command_payload_encode_payload to encode Command
4846 Payload buffer from SilcCommandPayload structure.
4848 * Added silc_argument_payload_encode_payload to encode Argument
4849 payload buffer from SilcArgumentPayload structure.
4851 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Changed WHOIS command to support router connection on server side.
4854 The whois request is always sent to router unless the server is
4855 standalone server. After server has received the reply from the
4856 router will it send the reply to the client.
4858 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4859 broadcast received broadcast packet. The function is used only
4860 by router. The broadcast packet is always sent to the router's
4863 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4864 render given ID to printable string, for log files for example.
4866 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Made basic router to router connections working. At least they
4869 can now connect to each other but nothing really works the way
4870 they are supposed - yet.
4872 * Added new initiator token to RouterConnection configuration
4873 file in silcd/serverconfig.[ch]. It is used to tell whether we
4874 are the initiator to the remote router or whether we'll expect
4875 the other end to connect.
4877 * Moved registering of listener task to silc_server_init, hence
4878 the server starts listenning as soon as it is run, even if it
4879 does not have connections to other routers. Let's see how well
4882 * Changed default connection retry timeouts for more suitable in
4885 * Removed cipher and such arguments from silc_idlist_add_client
4886 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4887 Added new function silc_idlist_add_data to add the keys and stuff
4890 * Added SilcIDListData structure and added it to SilcClientEntry
4891 and SilcServerEntry as their first field in the structure. This
4892 way we can explicitly cast the ID entries to the SilcIDListData
4893 structure and get common data for the entries. In past, we had
4894 to first check what type of connection it is and then cast it to
4895 correct ID entry type. Now, we can directly cast the opaque
4896 pointer to the SilcIDListData (no matter what ID entry it actually
4897 is) and get the data needed.
4899 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4902 in some circumstances even if threre were timeout tasks, though not
4903 IO tasks, but tasks anyway. Now fixed.
4905 * Defined SilcServerConnection structure to hold connection specific
4906 stuff about directly connected servers and routers. The definition
4907 is currently in silcd/server_internal.h. I thought about having
4908 a bit more important role fro this struct but for now it is used
4909 only when connecting to other server (or router actually).
4911 * Added connecting retry support in server when connecting to
4912 router(s). The retry feature implement exponential backoff
4913 algorithm. Also, added SilcServerParams structure to hold default
4914 parameters for server. For now, it include these retry settings
4915 and are hard coded. After server is moded to be as Silc Server
4916 Library this structure will be more important.
4918 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Changed client librarys channel->clients table to SilcList and
4921 changed code accordingly.
4923 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Changed client's channel table to SilcList and changed code
4926 accordingly. Also changed SilcChannelClientEntry to include back-
4927 pointer to the channel so that client entry can use that structure
4928 as list as well and we have fast cross-reference to the channel.
4929 This change dramatically decreased the complexity of channel
4930 handling with client entry and vice versa (removed one extra
4931 loop when searching for channel entry from many functions).
4933 * Changed server->sim from table to SilcDList and changed code
4936 * NAMES command can now be used from user interface. It will show
4937 the user list on the channel, neatly.
4939 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4940 Code now saves realname of the user if it becomes available.
4942 * Renamed configure.in to configure.in.pre and made ./prepare
4943 script to automatically add correct version string to
4944 configure.in which it creates from configure.in.pre.
4946 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * NAMES command reply now shows users mode with the nickname when
4951 * Moved silc_client_ch[u]mode[_char] functions from
4952 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4953 place sucks, they are utility functions and should be in some
4956 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4958 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4961 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Added TRQ (efficient deque and list library) into lib/trq. This is
4966 a very good list library that is currently used in the SILC. Defined
4967 SilcList API over the library because I didn't like the API very
4968 much. See lib/trq/silclist.h for the API and examples of how to
4969 use the API. Fixed various places in the code to use the new
4970 SilcList API. The SilcList is meant for lists that has a structure
4971 already defined as a list. It is not suitable to add just some
4972 context to the list (in TRQ, the context is the list actually).
4974 So, I defined SilcDList that can be used for the purpose where
4975 predefined list structure does not exit. This can be used as
4976 such list. Now some context just can be added to the SilcDList.
4977 Currently this list is not used in the SILC just yet, though there
4978 are a lot places where this can replace dynamically allocated
4979 tables and I will fix these places, later, to use SilcDList.
4980 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4981 and use TRQ internally).
4983 Also fixed some annoying warning messages that the original TRQ
4984 code generated. Also minor changes to TRQ's Makefile.in.
4986 * Added support for querying by Client ID to both WHOIS and
4987 IDENTIFY commands into server, as required by the protocol.
4989 * Removed method function pointers from SilcBuffer structure. They
4990 weren't used to anything and just increased the context size for
4991 no good reason. This change also made silc_buffer_alloc and
4992 silc_buffer_free functions inline functions.
4994 * Disabled command flooding detection support until it's fixed so
4995 that it accepts commands in but does not execute them more than once
4998 * Added silc_net_localhost(), to return local hostname, into
4999 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5000 that must be initialized before calling silc_client_init.
5002 * Added new function: silc_server_send_notify_on_channels to send
5003 notify messages to all channels client has joined. It is assured
5004 that the message is sent only once per client.
5006 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5007 lib/silcutil/silcutil.[ch] as silc_format function. The new
5008 function is generic and is used by server as well, not only by
5009 the logging routines.
5011 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5012 the provided version string was not acceptable. Added new function:
5013 silc_ske_check_version into lib/silcske/silcske.h. The function
5014 must be implemented by the application (client or server) and it
5015 does not reside in the SKE library. The function checks the version
5016 string remote end sent.
5018 * Added back pointers (to opaque context and to SilcSocketConnection)
5019 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5021 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5022 duplicate packet context structure.
5024 * Changed `notify' client operation to send same arguments as client
5025 receives from server except for ID's. ID's are mapped to correct
5026 ID entry and that is returned. Also, if channel entry is not sent
5027 by server but the notify is for channel the channel entry is sent
5028 to application (otherwise application doesn't know that it is for
5029 channel (library gets it from packet's Destination ID)).
5031 * Added silc_client_remove_from_channels into client library to
5032 remove a client from all channels it has joined to. Used when
5033 received SIGNOFF notify from server. Added also new function
5034 silc_client_replace_from_channels to replace old ID entry with
5035 new ID entry on all channels. Used when received NICK_CHANGE
5038 * Fixed ID Cache list handling in silc_idlist_get_client in
5039 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5040 to get (or query) client by ID.
5042 * Updated TODO list.
5044 * Added connection authentication status message defined by the
5045 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5046 support for these into the code in client and server side.
5048 * Added generic function silc_client_send_command to send any command
5049 with variable argument list. Application should use this function
5050 to send commands if the command functions provided by the library
5051 does not suite for the application's user interface needs.
5053 * Added new `failure' client operation. Application is notified about
5054 received failure packet if client is executing a protocol. In this
5055 case the protocol's execution has failed.
5057 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5058 is required by the protocol.
5060 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5061 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5064 * Added status flag to SilcSKE object to indicate realtime status
5065 of the SKE protocol.
5067 * Application receives now exactly same command reply arguments as
5068 the library receives from server. However, if ID is received the
5069 corresponding ID entry is returned to the application (eg. Client
5070 ID is mapped to correct SilcClientEntry entry and that is returned).
5071 Changed command_reply client operation due to this change.
5073 * Changed all ID's in commands and in command replys as ID Payloads.
5074 Change affected both client and server side codes.
5076 All ID's sent in SILC network (with execption of ID's in SILC
5077 Packet header) are sent in ID Payload to support variable length
5080 * Server now notifies nick changes and notifies all clients on
5081 the channels about the new nickname (about the new Client ID,
5084 * Implemented CMODE command to change channel modes. Supports all
5085 channel modes defined by the protocol specs except ban and invite
5086 lists. (Also, private channel key mode is supported but support for
5087 setting private channel key in client is missing, thus, this mode
5088 has no effect on client side (except that server requires that the
5089 client uses private channel key and normal channel traffic does not
5092 Also, invite mode works per se, but INVITE command does not work
5093 yet correctly, so you can set channel as invite only channel but
5094 inviting clients to the channel does not work (it is yet to be
5095 thought what's the best way to do it).
5097 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5098 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5099 Implemented CUMODE command to change user's mode on the channel.
5100 Supports all modes defined by the protocol specs.
5102 * Added NAMES command reply to return users modes on the channel.
5104 * Removed unnecessary and slow ciphers from lib/silccrypt.
5106 * Set SO_KEEPALIVE option to connection sockets by default.
5108 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5110 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5111 redefined the Notify Payload into protocol specs.
5113 * Added silc_id_payload_parse_id to get ID directly from raw
5116 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5119 accept searching by Client ID as well.
5121 * Added support for LEAVE and SIGNOFF notify types in client library.
5123 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5124 to parse ID Payload from raw data.
5126 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added flags parameter into silc_ske_assemble_security_properties
5129 function in lib/silcske/silcske.[ch].
5131 * Changed notify client operation to fit better for notify messages
5132 sent by server. The notify payload received from server is now
5133 passed to the application (after parsing it to SilcNotifyPayload).
5134 It is application's responsibility to retrieve the arguments
5135 from the payload and show the message the way it wants. The message
5136 sent by server is implementation specific.
5138 * Changed public keys to comply with the protocol specification.
5139 Old public keys are not supported anymore and are not compatible.
5141 * Removed nickname from Channel Payload as the latest draft removed
5142 it. The client must resolve the nickname from the NAMES command
5143 reply received when it joined the channel.
5145 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5147 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Fixed some errors in protocol specification drafts.
5151 * Created lib/silccore/silcnotify.c to implement Notify Payload
5152 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5153 generic payloads described by protocol specifications. The file
5154 includes implementations for ID Payload and Argument Payload.
5156 * Changed Command Payload implementation to use the new Argument
5157 Payload. Changed command_xxxx_payload to command_payload_xxxx
5158 to comply with SILC coding conventions.
5160 * Added suppport for Argument Payload handling in Notify Payload
5161 implementation as protocol requires it. Added the new support
5162 into server and client lib as well.
5164 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Added support for multiple nicknames on same channel. [n] is
5167 added locally to the nickname if there are more than one same
5168 nicknames on the channel.
5170 * Server now sends all nicknames that matched WHOIS request.
5171 Client also shows the list received from server.
5173 * Added TOPIC command to client side. User can now set and show
5174 current topic on channel.
5176 * Added MOTD command to client and server. Also, server sends the
5177 motd when client connects to the server.
5179 * Changed version strings to comply ISO 8601.
5181 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Fixed protocol error handling in client library. It should now
5184 cope even if the SKE fails for some reason.
5186 * Made new protocol specification drafts for submitting to IETF.
5188 * Implemented TOPIC command to server in silcd/command.c.
5190 * Added two new notify types into lib/silccore/silcnotify.h:
5191 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5192 notify nickname change and topic setting/change on a channel.
5194 * API change of command_reply operation in client library. The
5195 application gets now the status type received from server as well.
5197 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5201 * Cras fixed and optimized the packet handling even further and
5202 it should work now. Minor change to the prototype of function
5203 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5205 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added new function into lib/silcutil/silcschedule.[ch]:
5208 silc_schedule_with_fd to select() a specified fd. The function
5209 returns after timeout expires or data arrives or goes. The
5210 function is used by packet routines to wait that all data is
5211 received from network.
5213 * Fixed data reading from network in lib/silccore/silcpacket.c.
5214 The code now assures that all data is read from the fd and then
5215 continues packet processing. This was a bug fix since the code
5216 used to drop some data in some circumstances.
5218 * Added new function into lib/silcclient/client.[ch]:
5219 silc_client_start_key_exchange to start key exchange after
5220 connection has been established to server. The code internally
5221 now uses this funtion but its main purpose was to provide it
5222 for applications that perform their own connecting. After
5223 application has created a connection it merely calls this
5224 function to start the key exchange between client and server.
5225 The library takes care of everything else after that.
5227 Updated also lib/silcclient/README to explain the usage of
5230 * Do not send to application information that connection has
5231 been established. Application gets notified it by connect
5234 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Applied cras's patch to add silc_schedule_one function. The
5237 function runs scheduler once and returns.
5239 * Fixed the scheduler after cras messed it up. The timeout
5240 handling works now as it's supposed to work.
5242 * Added into lib/silccore/ silcnotify.h to include notify
5243 message types support. Changed silc_server_send_notify*
5244 functions, in server.[ch], to support those new notify types.
5245 Added the support for the notify types into client library,
5246 as well. Added new notify client operation into ops.h in
5249 * Changed silc_server_packet_send_to_channel to send normal
5250 packets instead of just channel message packets. The function
5251 is now used to send the notify packets to channels. It is not
5252 used to send channel message packets anymore, as server never
5255 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5256 va_arg()s as it seems to require it nowadays. I guess, if SILC
5257 is compiled with older va_arg() the new code should work anyway.
5259 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Splitted core library. Core library (lib/silccore) includes
5262 now only SILC protocol specific core (and common) components.
5263 Created new utility library (lib/silcutil) that includes more
5264 generic purpose stuff. The stuff for util library was taken
5265 from the old core library. This was minor and easy split.
5267 * Created SILC Client Library (lib/silcclient) that includes
5268 implementation of the SILC client without user interface. This
5269 was major move from silc/ directory. The code has been changed
5270 so that it is transparent towards the user interface. The
5271 silc/ directory includes now the same user interface as before
5272 and it uses the new client library. Read lib/silcclient/README.
5273 Basicly, the client library performs everything else related
5274 to SILC except user interface handling. Also, configuration
5275 files are considered to be part of user interface and library
5276 does not handle them.
5278 This change also changed a lot of structures, function naming etc.
5279 Most important change was that SilcClientWindow object was
5280 renamed to SilcClientConnection in the client library. Created
5281 also new file lib/silcclient/ops.h. Also added new files
5282 silc/local_command.[ch] and silc/client_ops.[ch].
5284 All these changes were made to make it easier for user interface
5285 designers to create what ever user interface for the SILC client
5288 It is also expected that the server will be moved to lib
5289 directory as well and SILC Server Library will be created;
5290 sometimes in the future.
5292 * Removed Local commands from lib/silccore/silccommand.h as
5293 they are application specific and new client library does not
5294 handle any of those anymore.
5296 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5297 old client implementation in silc/.
5299 * Added support for callback functions in SILC_LOG_* macros.
5300 Application can now set its own callbacks that will be called
5301 instead of using the default functions that will always print
5302 the debug messages to stderr (or stdout). Also, debugging can
5303 now be disabled by setting silc_debug to FALSE and re-enabled by
5304 setting it to TRUE. Note, that logging will still work even
5305 if debugging is disabled.
5307 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5308 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5309 silc_log_reset_debug_callbacks.
5311 * To enable debugging in silc client one must give now -d
5312 option on command line.
5314 * Changed silc_schedule_init to automatically allocate task queues
5315 if they are not allocated before calling it.
5317 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Added GMP 3.1 into math library.
5321 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5324 a channel in SILC network. The packet is used by servers and
5325 routers to notify other routers that user has left a channel.
5326 This little feature was missing until now. Added the feature
5327 to protocol specification as well.
5329 Added functions: silc_server_send_remove_channel_user and
5330 silc_server_remove_channel_user into server.[ch].
5332 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5333 lib/silccore/silcpacket.h. However, they are not implemented
5336 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Fixed joining to a channel and sending channel messages
5339 between server and router. The channel message sending should
5340 now work inside a cell.
5342 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Fixed the private message sending between server and router.
5345 The private message sending should now work inside a cell.
5347 * Added silc_server_replace_id into server.[ch] to replace
5348 existing ID in the SILC network.
5350 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5351 and silc_idlist_replace_server_id into idlist.[ch] in server.
5353 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Fixed the server to server connections. Server can again now
5356 connect to router. Router to router connections probably does
5359 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Added dynamic protocol registering support. Now protocols can
5362 registered and unregistered on the fly. Patch by cras.
5364 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Added lib/contrib directory to hold routines that some platforms
5367 don't have but are needed by SILC.
5369 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5370 into lin/contrib to provide getopt() and getopt_long() for
5371 those who don't have it.
5373 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Added AWAY command to client. When away message is set and
5376 client receives a private message packet the client automatically
5377 replies to the sender with the away message.
5379 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5380 bug seemed to be the cause of recent problems when compiling
5383 * Added version detection support to SKE protocol specification
5384 and added the new changes to the SKE implementation as well.
5385 There were other minor changes in the SKE protocol as well.
5387 Many changes in lib/silcske/silcske.[ch] and in
5388 lib/silcske/payload.[ch].
5390 * Added ^U functionality, clear input line. Patch from cras.
5392 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Mainly small bugfixes on core library. Fixed some debugging
5395 logging and buffer overflow in silclog.c.
5397 * Updated config.sub and config.guess on the distribution tree.
5399 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Added command lagging support in server. Client may execute
5402 commands now only once in two seconds.
5404 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Optimized packet reception. MAC computation and checking is now
5407 also more optimized. A lot previously duplicated code is now
5408 used as generic by both client and server.
5410 * Fixed key pair generation in clientutil.c
5412 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Added into lib/silccore/silcbufutil.[ch] new function;
5415 silc_buffer_realloc.
5417 * Moved generic packet sending/encryption functions to
5418 lib/silccore/silcpacket.[ch] from client and server. Some
5419 rewriting of the functions.
5421 * Moved all generic packet reception/decryption functions to
5422 lib/silccore/silcpacket.[ch] from client and server. The
5423 packet processing is now much cleaner in both client and server.
5424 These were major changes in both client and server.
5426 * Created many common functions in server to do packet sending.
5427 Previously code were duplicated a lot, this has been removed
5430 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Rewrote major parts of the ID cache system. Don't know
5433 whether it is better now or not but at least the API is more
5436 * Major rewrite on ID cache stuff on client because of the ID
5437 cache API changes. Added idlist.c to client.
5439 * Also major rewrite on ID cache stuff on server as well.
5440 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5441 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5442 in hand, instead they are all put into the ID cache system now.
5443 All server_idlist_* routines uses ID cache now instead of
5444 traversing its own lists (those lists does not exist anymore).
5445 SilcIDList though still exists. Also, SilcXXXEntry's are
5448 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Finally made the SKE implementation compliant to the protocol
5451 specification. All mp integers are now binary encoded as
5452 opposed being HEX encoded.
5454 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5457 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5458 functions: silc_[encode/decode]_pem. Also added function
5459 silc_encode_pem_file to PEM encode with newlines ('\n') for
5462 * SILC public keys are now encoded either PEM or binary. Same
5463 option is for private keys as well. By default private keys
5464 are binary encoded and public keys PEM encoded. Silly HEX
5465 encoding were removed.
5467 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5468 function to create fingerprints.
5470 * Fixed a bug in SHA1; does not change the original data anymore.
5472 * Partly implemented INFO command on client and server side.
5473 Fixed CLEAR command. Changes to SERVER command; show current
5474 server(s) when giving command without arguments. Added
5475 VERSION command to client.
5477 * Added check to server that unregistered connections cannot
5478 execute commands (unless it is specificly allowed).
5480 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Fixed screen refresh.
5484 * Fixed channel joining bug from client. On some circumstances
5485 client tried to join to a channel it had already joined.
5487 * Added public key verification process into client's protocol.c.
5488 The client now verifies the public key from user and saves
5489 it into ~./silc/serverkeys/ directory.
5491 Added into: clientutil.[ch]: silc_client_verify_server_key.
5493 * Changed SKE protocol's silc_ske_initiator_finish function
5494 to accept callback function that verifies the received public
5495 key. Removed old silc_ske_verify_public_key function.
5497 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5500 silc_pkcs_private_key[_data]_set.
5502 * Made the password and public authentication more cleaner in
5503 server's protocol.c.
5505 * Removed historic and obsolete protocol `channel_auth' from
5506 both client and server.
5508 * Removed wrong way of sending command status messages from
5509 server to client in server's command.c. The old way violated
5510 protocol specification.
5512 Changes to silccore/silccommand.[ch]: removed
5513 silc_command_encode_status_payload -> not needed anymore,
5514 changed silc_command_encode_payload_va to accept extra
5515 argument on variable argument list. The argument type must
5516 now be provided to the function. Also, added new function:
5517 silc_command_encode_reply_payload_va which is same as
5518 normal command_encode_payload_va except command status type
5519 is provided as extra argument.
5521 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Added ~./silc directory handling. The directory includes the
5524 public and private keys for the client.
5526 Added silc_client_check_silc_dir, silc_client_create_identifier
5527 and silc_client_load_keys.
5529 * Implemented SILC protocol compliant public key. Added public
5530 and private key saving to and loading from files.
5532 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5533 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5534 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5535 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5536 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5538 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5539 silc_pkcs_load_[public/private]_key.
5541 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Added silc_server_get_route (route.[ch]) to get connection
5544 data for the fastest route for given ID.
5546 * Implemented INVITE command on client and server. The command
5547 were re-defined in the SILC Protocol Specification and the
5548 implementation now complies with the specification.
5550 * Implemented PING command on client and server.
5552 * Implemented NAMES command on client and server. The server side
5553 supports currently only normal server not router server yet.
5554 Some changes to NAMES definition in SILC protocol specification.
5556 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Implemented LEAVE command on client and server.
5560 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5561 again. This change was made to the protocol as well. Server
5562 should not violate the protocol specification anymore.
5564 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5567 was tested. SOCKS4 was not but should work anyway.
