3 * Allow backup router to announce servers. All servers
4 announced by backup router are added to the global list
5 automatically. Update hte server's socket to our primary
6 router also when backup router announces a server.
7 Affected file silcd/packet_receive.c.
9 * Do not update the client->router in the function
10 silc_server_udpate_clients_by_server if the client is on
11 global list. We might fail to find any specific server
12 for locally connected clients and local cell clients. They
13 should still use the `from' and not `to' as client->router.
14 This fixes backup router resuming protocol. Affected file
17 * Decrease channel statistics count only if the channel
18 deletion worked. Affected files are silcd/server.c and
21 * Added silc_server_update_servers_by_server to update origin
22 of all server entries. Used during backup router protocol.
23 Affected files silcd/server_util.[ch], silcd/server.c. and
24 silcd/backup_router.c.
26 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
27 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
28 silc_hmac_get_hash and silc_hmac_get_name. Affected file
29 lib/silccrypt/silchmac.c.
31 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
33 * Assure that router cannot reroute the same channel message
34 to the sender. Affected file silcd/packet_receive.c.
36 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
38 * Made better checks that the channel message is not sent
39 to the router it came from. Affected file is
40 silcd/packet_send.c. Fixed memory leak too.
42 * Announce informations for incoming router connection, but
43 only after checking if it is replaced by backup router.
44 Affected file silcd/packet_receive.c.
46 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
48 * Fixed the backup resuming protocol to work in multiple
49 router environment. Affected file silcd/server_backup.c.
51 * Route packet only to one router in the function
52 silc_server_packet_send_to_channel. Affected file is
55 * Fixed silc_server_send_notify_dest to set the broadcast
56 flag. Fixed the silc_server_send_notify_topic to actually
57 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
58 Affected file silcd/packet_send.c.
60 * Changed the SFTP Filesystem interface. Changed the
61 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
62 the filesystem operation function. The SilcSFTPFilesystem
63 is now a context that is allocated by all filesystem allocation
64 functions and it already includes the operations structure
65 and filesystem specific context. It is given as argument
66 now to the silc_sftp_server_start. This made the interface
67 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
68 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
70 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
72 * Changed the backup router adding and getting interfaces
73 in the server. The router that will be replaced by the
74 specified backup router is now sent as argument. Affected
75 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
78 * Added silc_net_addr2bin_ne to return the binary form of
79 the IP address in network byte order. Affected files
80 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
82 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
84 * Check for existing server ID in silc_server_new_server
85 and in silc_server_connect_to_router_final and remove the
86 old entry if it exists. Affected file silcd/packet_receive.c,
89 * Send the channel message always to only one router, either
90 in upstream or downstream. Affected file is
93 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Wrote the definition of the backup resuming protocol to the
96 protocol specification.
98 * Removed one redundant channel key generation from normal
99 server during joining procedure. Removed one redundant
100 channel key sending from server to router during joining
101 procedure. Affected file silcd/command.c.
103 * Made minor bugfixes to the backup router resuming protocol.
104 Affected file silcd/server_backup.c, server.c.
106 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
108 * Added --disable-asm configuration option. Affected files
109 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
112 * Implemented the backup resuming protocol that is used to
113 resume the primary router position in the cell after the
114 primary router comes back online. Affected files
115 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
116 and silcd/server_util.[ch].
118 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Sleep two (2) seconds after sending QUIT command to server.
121 Affected file lib/silcclient/command.c.
123 * Assure that if outgoing data buffer is pending do not force
124 send any data. Affected file silcd/packet_send.c.
126 * Assure that if outgoing data buffer is pending do not force
127 send any data. Affected file lib/silcclient/client.c.
129 * Implemented the backup router support when the primary router
130 goes down. The servers and routers can now use the backup
131 router as new primary router without loosing connectivity.
133 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
135 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
136 in the server to indicate disabled entry. All data read
137 from the connection will be ignored and no data is sent
138 for entry that is disabled. Affected files are
139 silcd/idlist.h, silcd/server.c.
141 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Created SFTP client and server test programs in the
144 lib/silcsftp/tests directory.
146 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
148 * Implemented memory filesystem (virtual filesystem) for
149 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
152 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Implemented the SFTP (SSH File Transfer Protocol) to the
155 lib/silcsftp. It includes SFTP client and SFTP server
158 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
160 * Moved lib/silccore/silcprotocol.[ch] to the
161 lib/silcutil library.
163 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
164 take variable argument list pointer as argument. Affected
165 file lib/silcutil/silcbuffmt.[ch].
167 * Added silc_buffer_set function that is used to set data
168 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
169 Affected file lib/silcutil/silcbuffer.h.
171 * Changed various routines in the core library to use the new
172 silc_buffer_set instead of allocating new buffer only for
175 * Added 64-bit value formatting and unformatting support to the
176 silc_buffer_[un]format routines. Affected file is
177 lib/silcutil/silcbuffmt.[ch].
179 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
180 to includes/bitmove.h.
182 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Fixed channel user mode saving in client library. Affected
185 file lib/silcclient/command[_reply].c.
187 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
189 * Defined the file transfer to the SILC Protocol. Added
190 new packet type SILC_PACKET_FTP and defined File Transfer
191 Payload. The mandatory file transfer protocol is SFTP
192 (SSH File Transfer Protocol). Affected file in addition
193 of the internet draft is lib/silccore/silcpacket.h.
195 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
196 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
197 is used as part of backup router protocol when the primary
198 router of the cell is back online and wishes to resume
199 the position as primary router.
201 * Redefined the MAC generation keys in the protocol. The
202 same key is not used anymore in both direction. Both
203 direction will now use different keys for sending and
204 receiving. This fixes a potential security flaw. This
205 change causes incompatibilities in the protocol.
207 * Redefined also the MAC computation from the packet.
208 An packet sequence number is now added to the MAC
209 computation. This prevents possible replay attacks against
210 the protocol. This change too causes incompatibilities
213 Added `sequence' field to the SilcPacketContext to hold
214 the current sequence number for the packet.
216 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Added `created' field to the SilcIDListData in the file
219 silcd/idlist.h to indicate the time when the entry was
222 * Added `created' field to the SilcChannelEntry too. Affected
225 * Added `creation_time' aguments to all the announcement functions
226 in the server. If it is provided then only the entries that
227 was created after the provided time frame are actually
228 announced. Affected file silcd/server.[ch].
230 * The protocol says that the Channel ID's IP address must be
231 based on the router's IP address. Added check for this in
232 the silc_server_new_channel when processing incoming New Channel
233 Payload. Affected file silcd/packet_receive.c.
235 * Print out the correct version with --version in SILC client.
236 Affected file irssi/src/silc/core/silc-core.c.
238 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
240 * Fixed WHOWAS command to check for completnes of the client
241 entry always, not just when the command is coming from client.
242 Affected file silcd/command.c.
244 * Added new function silc_server_packet_queue_purge to purge the
245 outgoing data queue to the network. After the function returns
246 it is guaranteed that the outgoing packet queue is empty.
247 Affected file silcd/packet_send.[ch].
249 * Purge the outgoing packet queue in the rekey protocol's final
250 callback to assure that all rekey packets go to the network
251 before quitting the protocol. Affected file silcd/server.c.
253 * Added silc_client_packet_queue_parse as similar function as
254 in server to the client library. The affected file is
255 lib/silcclient/client.c.
257 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
259 * Splitted silcd/server.c and created silcd/server_util.[ch]
260 for utility functions.
262 * Added new socket flag SILC_SF_DISABLED to indicate that the
263 connection is open but nothing can be sent to or received from
264 the connection. Affected file lib/silcutil/silsockconn.[ch].
265 The checking for disabled socket is checked in the low level
266 silc_socket_write and silc_socket_read functions.
268 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
270 * Allow only nicknames and channel names that fits into the
271 7-bit unsigned char ASCII set. Affected file silcd/command.c.
273 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
275 * When processing JOIN command reply in server check that if
276 the channel exists in our global list we'll move it the local
277 list. Affected file silcd/command_reply.c.
279 * Fixed the check whether client is joined on the channel already
280 in JOIN command. Affected file lib/silcclient/command.c.
282 * Fixed the JOIN command reply to check whether the channel
283 already exists. Affected file lib/silcclient/command_reply.c.
285 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
287 * Added silc_ske_status_string to map the SKE error numbers
288 to readable strings. The affected files are
289 lib/silcske/silcske[_status].[ch].
291 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
293 * Do not show the private channels on the WHOIS channel list
294 as it is not allowed by the protocol. The affected file is
297 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Assure that the packet length digged from the actual packet
300 is something sensible in the silc_packet_decrypt_rest_special
301 in lib/silccrypt/silcpacket.c.
303 * Free and NULL the allocated pointer in silc_hmac_alloc if
304 the HMAC allocation fails. The affected file is
305 lib/silccrypt/silchmac.c.
307 * Print the selected security properties to the log files in
308 the server. Affected file silcd/protocol.c.
310 * Add SKE's reference counter even if calling the completion
311 callback manually. Otherwise it goes negative, although it
312 does not cause any problems. The affected file is
313 lib/silcske/silcske.c.
315 * Remove the client entry with short timeout after giving the
316 KILL command. Affected file lib/silcclient/command.c.
318 * Fixed to send error reply in WHOIS and IDENTIFY commands in
319 case all found clients are already disconnected (WHOWAS would
320 found them) in the server. Affected file silcd/command.c.
322 * Update the last_receive (time of last data received) to be
323 updated only when received private or channel message so that
324 the idle time showed in WHOIS makes more sense.
326 * Added boolean field `valid' in to the SilcClientEntry in the
327 client library to indicate whether the entry is valid or not.
328 This fixes the nickname change bug on channel when changing
329 the nickname to be same than the old (like nick to Nick) the
330 nickname formatter doesn't set the new nick anymore to Nick@host.
331 Affected file lib/silcclient/idlist.[ch].
333 * Now actually fixed the nickname changing on disconnection.
334 Added new function silc_change_nick to the Irssi SILC Client.
335 Affected file irssi/src/silc/core/client_ops.c,
336 irssi/src/silc/core/silc-nicklist.[ch].
338 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
340 * Check that the public key exists in the GETKEY command before
341 trying to encode it. Affected file silcd/command.c.
343 * Print some notifications on received public keys with GETKEY
344 command in the Irssi SILC Client. Affected files are
345 irssi/src/fe-common/silc/module-formats.[ch],
346 irssi/src/silc/core/client_ops.c.
348 * Use IDENTIFY command to resolve the server information in the
349 GETKEY command instead of INFO command. Affected file
350 lib/silcclient/command.c.
352 * All command reply functions in the client library now calls
353 the pending command reply callbacks even if an error has
354 occurred. The server has done this a long time and now it was
355 time to move the client library to this as well. Now all
356 errors can be delivered back to the pending command reply
357 callbacks if necessary. Affected files are
358 lib/silcclient/command[_reply].[ch].
360 * Change the nickname on disconnection back to the username
361 because in reconnect the server will enforce it to it anyway.
362 Affected file irssi/src/silc/core/silc-servers.c.
364 * Fixed a config file parsing bug in the Irssi SILC client.
365 Affected file irssi/src/silc/core/clientconfig.c.
367 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
369 * When printing the channel mode on JOIN, verify that the
370 channel key and channel's HMAC are valid. Affected file
371 irssi/src/silc/core/client_ops.c.
373 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
375 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
376 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
377 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
379 * Removed channel key rekey task deleting from the function
380 silc_server_save_channel_key. Affected file silcd/server.c.
381 Added explicit timeout task context instead that is used to
382 delete the task if we are registering a new task before the
383 new task has elapsed.
385 * When channel key rekey occurs the client library now saves
386 the old channel key for a short period of time (10 seconds) and
387 is able to use it in case some is still sending channel
388 messages encrypted with the old key after the rekey. Affected
389 file lib/silcclient/[idlist.h|client_channel.c].
391 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Added check to the silc_server_new_id_real to not accept
394 new ID if it is the sender's own ID. Affected file is
395 silcd/packet_receive.c.
397 * Assure that we do not announce ourself or the one we've
398 sending our announcements when we're router and are announcing
399 servers to our primary router. Affected file silcd/server.c.
401 * Fixed silc_server_command_identify_check_client to assemble
402 correct WHOIS packet. It send corrupted WHOIS packet and
403 caused problem with router to router connections. Affected
404 file silcd/command.c.
406 Fixed also silc_server_command_whois_check the same way
407 as for the IDENTIFY command.
409 * Added new SilcIDListStatus to the server in the SilcIDListData
410 structure. The status now includes the current status of
411 the entry (like registered, resolved etc.). Affected file
412 silcd/idlist.[ch]. Defined a bunch of different status types
413 as well. This replaced the old boolean registered field as well.
415 Added resolve_cmd_ident field to the SilcClientEntry structure
416 too so that if the entry is for example being resolved so
417 another command may attach to the same pending command reply
418 without requiring to resolve the same entry again. This concept
419 should optimize the WHOIS and the IDENTIFY resolving under
420 heavy load by taking away unnecessary resolving for entries
421 that are being resolved already.
423 Added support for adding multiple pending commands for one
424 command idenfier. Affected file silcd/command[_reply].[ch].
426 * Fixed WHOIS and IDENTIFY save to remove the cache entry
427 before deleting the data. Otherwise the hash table will have
428 freed data in comparison functions. Affected file is
429 silcd/command_reply.c.
431 * Fixed silc_idlist_replace_client_id to add the new entry to
432 the cache with NULL nickname. Otherwise there will be invalid
433 memory as the nickname after the nickname is freed. Affected
434 file silcd/packet_receive.c.
436 * Fixed the silc_idlist_get_clients_by_hash. The entries was
437 saved into wrong slots because the previous number of entries
438 was not taken into account. Affected file silcd/idlist.c.
439 Fixed same thing in silc_idlist_get_clients_by_nickname too.
441 * If we are router and we receive JOIN notify to a channel that
442 does not have any users then notified client is marked as the
443 channel founder, as it is it. The affected file is
444 silcd/packet_receive.c
446 * Added to the extended hash table API's table_del_*ext functions
447 the destructor as argument too, so that the caller can decide
448 which destructor to use or whether to use destructor at all.
449 Affected file lib/silcutil/silchashtable.[ch].
451 * Fixed ID Cache purging. It actually deleted the entries from
452 the hash table after the data was freed. The hash table ended
453 up comparing freed memory. The affected file is
454 lib/silccore/silcidcache.c.
456 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Fixed Irssi SILC client's KILL command's HELP syntax.
460 * The USERS command now resolves the detailed user information
461 if the userinfo field is missing. Affected file is
462 lib/silcclient/command_reply.c.
464 * Do not print error in silc_file_read if the read file does
465 not exist. Just silently return NULL. Affected file is
466 lib/silcutil/silcutil.c.
468 * Fixed the silc_log_output to not wine about NULL filename
469 and to not create some bogus " " filename. Affected file is
470 lib/silcutil/silclog.c.
472 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
474 * Fixed various printing bugs on the user interface in the
475 Irssi SILC Client. Minor changes that were forgotten from
478 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
480 * Fixed the configure.in.pre and the compilation and distribution
481 environment to support the new autoconf 2.52. That version is
482 now required to compile the CVS trunk.
484 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
486 * Renamed function silc_parse_nickname to silc_parse_userfqdn
487 to generally parse user@fqdn format strings. Affected file
488 lib/silcutil/silcutil.c.
490 * Added nickname_format and nickname_force_format fields to the
491 SilcClientParams structure. The first one defines the format
492 for the nicknames that the library will enforce if the receives
493 multiple same nicknames. The second one is boolean value and
494 can be used to force the library to always enforce the format
495 to the nicknames regardles whether there are multiple nicknames
496 or not. This configurable formatting was employed to flexibly
497 support accessing multiple nicknames from the user interface.
498 The userinterface can now set the nicknames to what ever format
499 they prefer. Affected file lib/silcclient/silcapi.h.
501 Added function silc_client_nickname_format to the file
502 lib/silcclient/idlist.c. It performs the nickname formatting.
504 Added new field `hostname´ to the SilcClientEntry context.
505 It holds the hostname of the client. Affected file is
506 lib/silcclient/idlist.h.
508 * Irssi SILC Client sets the nicknames in nick@hostn format.
509 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
510 irssi/src/silc/core/silc-core.c.
512 The WHOIS printing now also shows both the real nickname and
513 the formatted nickname so that user knows how to access the
514 user if there are multiple same nicknames cached. Affected
515 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
516 printing formatting too to take the hostname now as a separate
517 argument. The Affected file is
518 irssi/src/fe-common/silc/modules-formats.[ch].
520 * Changed the silc_client_get_clients_local to accept the formatted
521 nickname as argument. It accepts the real nickname too but the
522 formatted nickname can be used to find the true entry from
523 multiple entries. Affected file lib/silcclient/silcapi.h and
524 lib/silcclient/idlist.c.
526 * Added nickname_format_parse field to the SilcClientParams.
527 It is a callback function provided by the application to parse
528 the nickname out of the formatted nickname string. The library
529 calls it to get the nickname from the formatted string. Since
530 the application generally knows better the format of the nickname
531 string it parses it instead of the library, even though library
532 encodes the formatted string. If the callback function is not
533 provided then the library will use the string as is. The
534 affected file is lib/silcclient/silcapi.h.
536 * All the nickname strings passed to the client library in
537 commands are now expected to be formatted nickname strings.
538 If the command does not support the formatted nickname string
539 it will assume that the sent string is the actual nickname.
540 Affected file lib/silcclient/command.c.
542 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Added public key authentication support to OPER and SILCOPER
545 commands in the client library. Affected file is
546 lib/silcclient/command.c.
548 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Changed the get_auth_methdod client operation to be asynchronous.
551 It can be async if the application resolves the authentication
552 method from the server during the negotiation. Added new
553 SilcGetAuthMeth completion callback that the application will
554 call after resolving the authentication method.
556 Added function silc_client_request_authentication_method that
557 the application can use to resolve the authentication method
558 from the server. Added also SilcConnectionAuthRequest callback
559 that the library will call after the server has replied. The
560 application can call this function if it does not know the
561 current authentication method.
563 Affected files are lib/silcclient/client.c and
564 lib/silcclient/silcapi.h.
566 * The Irssi SILC client now automatically resolves the authentication
567 method incase any configuration information is not present (and
568 currently there never is). The affected file is
569 irssi/src/silc/core/client_ops.c.
571 * Fixed public key authentication from the client library.
572 Affected file lib/silcclient/protocol.c. Changed also the
573 protocol specification about the public key authentication in
574 the connection authentication protocol. The actual data to be
575 signed is now computed with a hash function before signing.
577 * Fixed the public key authentication from the server as well.
578 Affected file silcd/protocol.c.
580 * Removed the mlock()'s from the memory allocation routines.
581 Affected file lib/silcutil/silcmemory.c. The ./configure does
582 not check anymore for the mlock(). Affected file is
585 * Fixed USERS command in server to allow the execution of the
586 command for private and secret channels if the client sending
587 the command is on the channel. Affected file silcd/command.c.
589 * Fixed silc_client_get_clients_local to return the clients
590 count correctly. It could return wrong value. Affected file
591 lib/silcclient/idlist.c.
593 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
595 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
596 types. The assembler optimizations seemed not to like 64-bit
597 data types. The assmebler optimizations thus are now enabled
598 also for BSD systems as opposed to only enable them for Linux.
600 * Do not check for threads at all on BSD systems. Affected
601 file configure.in.pre.
603 * Removed -n and -h options from the Irssi SILC Client since
604 they are not used in silc.
606 * Fixed the prime generation to assure that the first digit
607 of the generated random number is not zero since our conversion
608 routines does not like number strings that starts with zero
609 digit. If zero digit is seen the random number is regenerated.
610 This caused some corrupted RSA keys when the zero first digit
611 was met. Affected file lib/silcmath/silcprimegen.c.
613 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
615 * Fixed WIN32 configuration in the ./configure script.
616 Fixed to include xti.h on environments that has it.
617 Patches by Carsten Ilchmann and andrew.
619 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
621 * Changed the silc_id_create_client_id to be collision
622 resistant. It is now assured that there cannot be created
623 two same client ID's. I suspect that some weird bugs in
624 the server were actually caused by duplicate Client IDs.
625 Affected file silcd/serverid.[ch]. A router receiving
626 new ID now also assures and informs the sending server
627 if the ID caused collision.
629 * Changed the silc_id_create_channel_id to also assure that
630 there are no collisions.
632 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Statement about ignoring the Mutual Authentication flag when
635 performing rekey with PFS was a bit misleading. It is ignored
636 if it was set in the initial negotiation, it cannot be even
637 set in the rekey. Fixed in the ke-auth draft. Started the
638 new versions of the protocol drafts in the doc/.
640 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
642 * Fixed a bug in silc_client_command_identify_save when saving
643 new channel information. The channel name was no duplicated
644 and caused crash on exit. Affected file is
645 lib/silcclient/command_reply.c.
647 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
649 * Fixed the getkey command handling in the server. Send just
650 empty OK reply to the sender if the key could not be fetched
651 (but everything else was ok, like the key just was not available).
652 Changed the public key parameter to optional in the protocol
653 specs so that empty OK reply can be sent. Affected file
656 Added a message to Irssi SILC client to tell to user if the
657 server did not return a public key.
659 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
661 * Fixed a channel key regeneration bug. It registered new
662 timeout tasks exponentially until all system resources were
663 used. Affected file silcd/server.c.
665 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Added the SILC Document generator to the scripts/silcdoc.
668 It can be used to generate the Toolkit Reference Manual out
669 of the source tree. Internally it will also use the RoboDoc
670 generator now imported in util/robodoc.
672 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Added couple of return's in rekey protocol if error orccurred
675 during the protocol. The execution must be terminated.
676 Affected file silcd/protocol.c. Also, terminate the protocol
679 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
681 * The client's Client ID was created initally from the wrong
682 nickname (it could have been in format nick@host) in the
683 silc_server_new_client. Affected file silcd/packet_receive.c
685 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Added some SILC_LOG_ERROR's to various error conditions
688 if client could not be added to ID cache. Affected files
689 silcd/packet_receive.c and silcd/server.c.
691 * When client's sock->user_data is freed, NULL also the
692 client->router and client->connection pointers. Added check
693 for these pointers being NULL to various places around the
694 code. Affected file silcd/server.c.
696 * Added client->data.registered == TRUE checks to various
697 places around the code to assure that unregistered client's
698 are not handled when it is not allowed. Affected file
701 * Added `bool registered' fields to all
702 silc_idlist_[server|client]_get_* routines to indicate whether
703 the fetched client needs to be registered or not. Affected
704 file silcd/idlist.[ch].
706 * Add your own entry as registered to the ID cache in the
707 server. Affected file server.c.
709 * Fixed a bug in silc_server_new_server. The SilcServer was
710 set as the new server's context instead of SilcServerEntry.
711 This naturally caused some weird bugs.
713 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Do not delete the channel rekey task when adding it
716 for in silc_server_create_channel_key.
718 * Changed the silc_server_create_channel_key to return
719 TRUE or FALSE to indicate the success of the channel key
722 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
724 * Fixed MSVC++ project files and added missing files to
725 Makefiles under win32/.
727 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Do not add TCP_NODELAY flag if the operating system
730 does not have it defined. Affected files are
731 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
733 * Fixed buffer overflow from Irssi SILC Client. Affected
734 file irssi/src/fe-common/core/themes.c.
736 * Fixed double free in client library in the file
737 lib/silcclient/client.c when disconnecting from server.
739 * Applied double free patch from cras to Irssi SILC client.
740 Affected files irssi/src/core/[modules/expandos].c
742 * Fixed the disconnection handling to Irssi SILC Client.
743 The application must call silc_client_close_connection
744 in ops->connect client operation in case of failure of
745 the connection. Affected file is
746 irssi/src/silc/core/client_ops.c.
748 * Do not set sock->protocol to NULL in the function
749 silc_client_close_connection after executing the protocol's
750 final callback since the sock might not be valid anymore.
751 Affected file lib/silcclient/client.c.
753 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Do not enable SILC_THREADS if the linking with libpthread
756 did not happen. Affected file configure.in.pre.
758 * Added notion to protocol specification that server must
759 verify the sent authentication payload with CMODE when
760 setting the channel founder key. Implemented it to the
761 server. Affected file silcd/command.c.
763 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Added _EXTRA_DIST SILC distribution variable to the
766 distributions file. It is used to conditionally add extra
767 files or directories to the specific distribution. Affected
768 files ./prepare, Makefile.am.pre and distributions.
770 Removed the `_' from the start of the distribution names.
773 * Added README.WIN32 for instructions to compile the Toolkit
776 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
778 * Fixed a double free in disconnection in the server. Affected
779 file is silcd/server.c.
781 * Fixed the lib/silcske/groups.c to work now also with GMP
782 MP library. The string conversion did not work when using
783 specific base and the base is indicated in the string as well.
785 * Created win32/ directory which now includes MSVC++ specific
786 stuff so that toolkit (DLLs) may be compiled with MSVC++.
787 It will appear only in the toolkit distribution
789 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
791 * Changed the key material distribution function in case when
792 the hash output is too short. The data is now concatenated
793 a bit differently than it used to. Made the change to the
794 SKE protocol specification.
796 * Added better GMP detection to configure.in.pre. A patch
799 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Fixed a minor bug in SKE that might cause some problem on
802 some platforms. Affected file lib/silcske/silcske.c.
804 * Added the cookie checking for initiator in the SKE. It checks
805 that the responder returns the sent cookie unmodified. The
806 affected file is lib/silcske/silcske.c. Added new SKE
807 error type INVALID_COOKIE that can be sent during the
808 negotiation. Fixed some memory leaks as well.
810 * Added the "invalid cookie" error message to Irssi SILC client's
813 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Added `task_max' field to the SilcClientParams to indicate
816 the maximum tasks the scheduler can handle. If set to zero,
817 default values are used. Affected file lib/silcclient/silcapi.h.
819 * Fixed memory leaks in silc_client_close_connection. Affected
820 file lib/silcclient/client.c.
822 * Added silc_client_del_client_entry to client library to free
823 all memory of given client entry. Affected file is
824 lib/silcclient/idlist.[ch].
826 * Added new functions silc_client_del_channel and
827 silc_client_del_server to delete channel and server entries.
828 Affected file lib/silcclient/[silcapi.h/idlist.c].
830 * Removed silc_client_del_client_by_id from silcapi.h.
832 * Fixed the INFO command to return the server's own info
833 correctly when querying by Server ID. Affected file is
836 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Removed the non-blocking settings in WIN32 code in the
839 silc_sock_[read/write] and added SleepEx instead. Affected
840 file lib/silcutil/win32/silcwin32sockconn.c. The availability
841 of input data is now checked with FIONREAD and ioctlsocket.
843 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Call silc_schedule_task_del_by_context in the
846 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
847 Affected file lib/silccore/silcprotocol.c.
849 * Call silc_protocol_cancel for active protocols in the
850 silc_server_close_connection if the funtion
851 silc_server_free_sock_user_data has not been called.
852 Affected file silcd/server.c.
854 * Generic tasks cannot be deleted using the del_by_fd
855 task deleting function since generic tasks does not match
856 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
858 * Added a notion to SILCOPER help file that the SILCOPER works
859 only on router server, not on normal server.
861 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
863 * Added for WIN32 support for the new scheduler as well.
864 Affected file lib/silcutil/win32/silcwin32schedule.c.
866 * Fixed the SHA1 implementation to work on various platforms.
868 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
871 API. It is part of the scheduler now. Everything else is
872 as previously but some functions has changed their names.
873 Checkout the lib/silcutil/silcschedule.h for the interface.
874 Updated all applications to use the new interface. Affected
875 files are lib/silcutil/silcschedule.[ch].
877 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
879 * Found a bug in the SKE implementation. The HASH value,
880 specified by the protocol, was not computed correctly. The
881 public key of the responder was not added to the computation
882 even though it is mandatory. Affected file lib/silcske/silcske.c.
883 This unfortunately causes incompatibilities with older
886 * Added WIN32 specific network init and uninit functions:
887 silc_net_win32_init and silc_net_win32_uninit to init and uninit
888 the Winsock2. Affected file lib/silcutil/silcnet.h and
889 lib/silcutil/win32/silcwin32net.c.
891 * Set the socket always to nonblocking mode on WIN32 after
892 reading data or writing data. Affected file is
893 lib/silcutil/win32/silcwin32sockconn.c.
895 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Fixed various compilation problems under WIN32. Affected
898 files lib/silcutil/win32/silcwin32thread.c and
899 lib/silcutil/win32/silcwin32schedule.c.
901 * Removed all _internal.h #includes from public header
902 files. Internal headers must never be included from
905 Removed also the lib/silcske/payload_internal.h file.
907 * All include files that may be needed (public and some others
908 included by the public headers) by application developers are
909 now copied to the ./includes directory. It does not copy any
910 internal headers. Affected file Makefile.defines.pre and all
911 Makefile.am's under lib/ and subdirs.
913 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
915 * Do not change the ~/.silc directory's permissions automatically.
916 Affected file irssi/src/silc/core/clientutil.c.
918 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Do not cancel the protocol in silc_server_close_connection
921 it might cause recursion. Now cancelled in the function
922 silc_server_free_sock_user_data. Affected file silcd/server.c.
924 * Fixed the silc_server_remove_clients_by_server to regenerate
925 the channel keys correctly finally. Added also new function
926 silc_server_remove_clients_channels to actually do it.
927 Affected file silcd/server.c.
929 * Fixed the silc_server_new_channel to not crash by giving
930 wrong router to the new channel. Affected file is
931 silcd/packet_receive.c.
933 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
936 which is given as argument to the silc_client_alloc now.
937 It can be used to configure the client and set various parameters
938 that affect the function of the client.
940 * The USERS command in server did not check whether the channel
941 is private or secret. Affected file silcd/command.c.
943 * Added new argument to the USERS command in protocol specification.
944 The USERS command now can take the channel name as argument
945 as well. Added support for this in client and server and
946 updated the protocol specs.
948 * Completed the GETKEY command in client. It can be now used
949 to fetch also servers public key not only some clients.
950 Affected files lib/silcclient/command[_reply].c.
952 * Added silc_client_get_server to return server entry by the
953 server name. Affected files lib/silcclient/silcapi.h and
956 * Redefined the IDENTIFY command in protocol specification to be
957 more generic. It now can be used to query information about
958 any entity in the SILC Network, including clients, servers and
959 channels. The query may be based either the entity's name
960 or the ID. Added support for this in both client and server.
962 Affected files silcd/command.c and lib/silcclient/command.c
965 * Optimized the WHOIS and WHOWAS commands in the server. Removed
966 the _from_client and _from_server functions. Affected file
969 * Added silc_client_get_channel_by_id_resolve to the file
970 lib/silcclient/silcapi.h to resolve channel information by
971 its ID. Added also silc_client_get_channel_by_id that
972 does not resolve it from the server.
974 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Added SilcServerEntry context into the client library
977 to represent one server. The INFO command now allocates
978 these to save the resolved server info. For now on the
979 client library will also keep information about servers,
980 connected and resolved with INFO.
982 The INFO command now allocates the SilcServerEntry context
983 and saves the server info there. The COMMAND_REPLY in
984 the INFO now returns the parameters to application in
985 same order as defined in the protocol specification.
987 The entries are cached in the client->server_cache.
989 * The INFO command is now issued after received the Client ID
990 from the server. Affected file lib/silcclient/client.c.
992 * The CMODE_CHANGE notify may now return also an SilcServerEntry
993 to the application as the mode changer might be server.
994 It is guaranteed that NULL is not returned anymore to the
995 application. Affected file lib/silcclient/client_notify.c.
997 The ID Type is now also passed to the application so that
998 it can check whether the returned entry is SilcClientEntry
1001 Added new function silc_client_get_server_by_id to return
1002 the server entry by ID. Affected files are the
1003 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1005 * Do not create the channel in the Irssi SILC Client when issuing
1006 the JOIN command but when received the sucessful JOIN command
1007 reply. Otherwise the channel might get created even though we
1008 could not join it. The Affected file is
1009 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1011 * Fixed a channel joining bug in router. The router must also
1012 check the channel modes, invite and ban lists etc. when serving
1013 the JOIN command sent by normal server. Affected file is
1014 silcd/command.c. The router now resolves the client's
1015 information from the server who sent the JOIN command if it
1016 does not know it, and processes the JOIN command only after
1019 * Changed the SilcCommandCb to take new argument; void *context2.
1020 Affected file lib/silccore/silccommand.h
1022 The second argument in the command callbacks in the server now
1023 includes the SilcServerCommandReplyContext if the command was
1024 called as pending command callback from the command reply.
1025 Otherwise it is NULL. When called as pending the status of the
1026 command reply will be checked and if it was erronous the
1027 error will be sent to the original sender of the command.
1028 This way the client always receives the error messages even
1029 though the server was actually the one who received the error
1030 when it resent the command to router, for example. Affected
1031 files silcd/command[_reply].[ch].
1033 * Fixed sending WHOWAS command's error message to client if
1034 the requested client could not be found. It was missing.
1037 * Changed the CMODE and CUMODE commands reply arguments in the
1038 protocol specification. The Channel ID is now sent in both
1039 of the commands to identify the channel. Implemented this
1040 new feature to the client and server. Affected files
1041 lib/silcclient/command_reply.c and silcd/command.c.
1043 * Made better checks for invite and ban lists in the JOIN
1044 command in server. Affected file silcd/command.c.
1046 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * The server now performs the incoming host IP/DNS lookup
1049 using the silc_socket_host_lookup and thus does not block
1050 the server anymore. Affected file silcd/server.c.
1052 * Completed the multi-thread support for SILC Scheduler in
1053 the lib/silcutil/silcschedule.c.
1055 * Fixed the configure.in.pre to detect the pthread correctly
1058 * Fixed a deadlock in silc_task_queue_wakeup in the file
1059 lib/silcutil/silctask.c.
1061 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * Added new function silc_schedule_wakeup that is used in
1064 multi-threaded environment to wakeup the main thread's
1065 schduler. It needs to be used when a thread adds a new task
1066 or removes a task from task queues. After waking up, the
1067 scheduler will detect the task queue changes. If threads
1068 support is not compiled in this function has no effect.
1069 Implemented the wakeup mechanism to both Unix and WIN32
1070 systems. Affected files are lib/silcutil/silcschedule.[ch],
1071 lib/silcutil/unix/silcunixschedule.c and the
1072 lib/silcutil/win32/silcwin32schedule.c.
1074 * Added new function silc_task_queue_wakeup to wakeup the
1075 scheduler by the specified task queue. Affected file
1076 lib/silcutil/silctask.[ch].
1078 * The silc_socket_host_lookup_start now wakes up the scheduler
1079 after adding the timeout task. Affected file is
1080 lib/silcutil/silcsockconn.c.
1082 * The silc_socket_host_lookup is synchronous now if the threads
1083 support is not compiled in. However, the callback is still
1084 called asyncronously through the scheduler, anyway. Affected
1085 file lib/silcutil/silcsockconn.c.
1087 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Added new function silc_socket_host_lookup to perform
1090 asynchronous IP and FQDN lookups for the socket connection.
1091 Affected files lib/silcutil/silcsockconn.[ch].
1093 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1096 that may or may not compile the mutex support in.
1098 Changed the silc_mutex_alloc interface. It allocates the
1099 mutex now to the sent pointer and returns TRUE or FALSE.
1101 Affected file lib/silcutil/silcmutex.h.
1103 * Wrote the SILC Task Queue interface to support multi-threads.
1104 Affected file lib/silcutil/silctask.[ch].
1106 * Wrote the SILC Scheduler to support multi-threads. Affected
1107 file lib/silcutil/silcschedule.c.
1109 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1112 in lib/silcutil/win32/.
1114 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Defined SILC Mutex API and SILC Thread API and implemented
1117 them for Unix. Affected files are
1118 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1119 lib/silcutil/unix/silcunixmutex.c and
1120 lib/silcutil/unix/silcunixthread.c.
1122 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1124 * Fixed the silc_server_remove_clients_by_server's channel
1125 key re-generation. The hash table handling was incorrect
1126 and would not work with many channels. Affected file is
1129 * Fixed some memory leaks around the server code.
1131 * Rewrote the silc_server_get_users_on_channel to support IPv6
1132 based Client ID's. Affected file silcd/server.c.
1134 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1135 specification. However, a separate document must be written
1136 to define the detailed signing procedure and the payload
1137 associated with the flag. Defined the flag to the
1138 lib/silccore/silcchannel.h as well.
1140 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Changed the dynamic tables to static size tables in the
1143 lib/silccrypt/silchmac.c.
1145 * Removed GCC dependencies from the code. A patch by cras.
1147 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Do not show the error "Error receiving packet bla bla"
1150 in server if it really was not an error (-2 means that reading
1151 is pending). Affected file silcd/server.c.
1153 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Fixed a possible crash in silc_server_remove_clients_by_server
1156 in silcd/server.c. Fixed there also some memory leaks.
1158 * Fixed the silc_idlist_replace_client_id. It could replace
1159 wrong key in the hash table. Affected file silcd/idlist.c.
1161 * Do not check whether there are global users on the channel
1162 if the channel->global_users is FALSE. Affected functions
1163 silc_server_remove_from_one_channel and
1164 silc_server_remove_from_channels in silcd/server.c. Also,
1165 do not check if the removed client is local as we can be
1166 sure that global client was not removed from the channel
1167 and checking for global users is not needed.
1169 * The silc_server_remove_clients_by_server now re-generates
1170 the channel keys correctly for those channels that had
1171 clients removed from them. Affected file silcd/server.c.
1173 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Found the reason of random crashes in the server. We weren't
1176 ignoring the SIGPIPE signal (which can be sent in write())
1177 and it crashed the server. Affected file silcd/silcd.c.
1179 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1181 * Assure that sock->user_data is not NULL in the function
1182 silc_server_packet_send in silcd/packet_send.c.
1184 * Disconnect the remote connection if it could not be added
1185 to any ID lists in the server. The affected file is
1188 * Check in silc_server_packet_send[_real/dest] that the
1189 socket is not disconnecting and ignore the data if it is.
1190 Affected file silcd/packet_send.c.
1192 * Define inline to __inline on native WIN32 compilation.
1193 Affected file includes/silcwin32.h.
1195 * Added some explicit type casts for inline code since MSVC
1196 require them. Affected files lib/silcutil/silcbuffer.h,
1197 lib/trq/silcdlist.h and lib/trq/silclist.h.
1199 * Print warning in log files from now on if the packet
1200 decryption fails. Affected file silcd/server.c.
1202 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Changed the `say' client operation's interface to accept
1205 new `type' argument to indicate the type of the message sent
1206 by the library. The application may filter the library's
1207 messages according the type. The affected file is the
1208 lib/silcclient/silcapi.h.
1210 * Added two new functions to lib/silcclient/silcapi.h:
1211 silc_client_del_client and silc_client_del_client_by_id.
1212 Affected file lib/silcclient/idlist.c.
1214 * Moved the clientincludes.h from includes/ to silc/ and
1215 serverincludes.h from includes/ to silcd/.
1217 * The modes for the CMODE and CUMODE are now passed as
1218 uint32 for application with COMMAND_REPLY. The affected
1219 file is lib/silcclient/command_reply.c.
1221 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * /WHOIS without arguments shows client's own information.
1224 Affected file lib/silcclient/command.c.
1226 * Changed PING to not accept any arguments. The specs
1227 says that client can ping only the connected server so
1228 requiring an argument is not needed. Affected file is
1229 lib/silcclient/command.c.
1231 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Fixed a fatal bug in private message sending and reception
1234 encryption and decryption when using private message keys.
1235 The implementation was incorrect and did not follow the
1236 specification. It causd that some of the message were
1237 lost since it did not use the sending and receiving keys
1238 as the protocol suggests. This has been fixed and will cause
1239 incompatibilities with older clients when sending private
1240 message encrypted with private message keys. Affected files
1241 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1242 and various other in Irssi SILC Client.
1244 Added `responder' boolean argument to the functions
1245 silc_client_add_private_message_key[_ske] to indicate when
1246 the key is added as responder or initiator of the key
1249 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1251 * Removed the silc_ske_check_version function and created
1252 a SilcSKECheckVersion callback. Added also a function
1253 silc_ske_set_callbacks that is now used to set all SKE
1254 callbacks. The callback functions are not given to
1255 the SKE functions anymore, but this function is used to
1258 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1260 * Added `silc_version' argument to the silc_client_alloc
1261 to define the version of the application for the library.
1262 The library will use the version string to compare it
1263 against the remote host's (usually a server) version
1264 string. Affected file lib/silcclient/silcapi.h
1266 * Added the KE protocol context to Key Agreement context
1267 in client library so that we can abort the SKE if it
1268 is in process when we get timeout. Affected file is
1269 lib/silcclient/client_keyagr.c.
1271 * Do not resolve the client ID forever if it returns in the
1272 first time that such client does not exist. This was done
1273 for example with private message. Affected file is
1274 lib/silcclient/client_prvmsg.c.
1276 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Do not add regex.h for WIN32. The affected file
1279 includes/silcincludes.h.
1281 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1282 not work yet 100%. It generates the DLL's automatically
1283 when compiling with --with-win32 under cygwin.
1285 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * lib/contrib/regex.c is not compiled on WIN32.
1289 * Added silc_net_get_socket_opt function to the
1290 lib/silcutil/silcnet.h.
1292 * Added includes/silcwin32.h for WIN32 specific includes
1295 * Do not use ptime structure or any of the posix process
1296 functions on WIN32 in lib/silccrypt/silrng.c.
1298 * Added silc_gettimeofday to provide generic function
1299 for struct timeval on all platforms. Added the function
1300 to lib/silcutil/silcutil.h.
1302 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1305 library as they clearly belong there. As a plus side we
1306 can make the actual socket connection routines platform
1309 Added also new generic function silc_socket_read and
1310 silc_socket_write (that used to be silc_packet_[read/write].
1311 The implementation of these are platform specific.
1313 * Added WIN32 specific routines of silc_socket_[read/write]
1314 to lib/silcutil/win32/silcwin32sockconn.c.
1316 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * Added preliminary support for native WIN32 compilation under
1319 cygwin (using the -mno-cygwin option for GCC) to the
1320 ./configure.in.pre. The --with-win32 now prepares the
1321 compilation for native WIN32.
1323 * Rewrote the SILC Scheduler interface in the file
1324 lib/silcutil/silcschedule.h. The scheduler is now context
1325 based and does not have anymore any global static scheduler.
1326 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1327 and created lib/silcutil/win32 directory for WIN32 based
1330 * Added Unix specific network routines to the
1331 lib/silcutil/unix/silcunixnet.c and the old
1332 lib/silcutil/silcnet.c includes now only generic routines.
1334 Added WIN32 specific network routines to the
1335 lib/silcutil/win32/silcwin32net.c.
1337 * Added Unix specific utility functions from the
1338 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1340 * Added WIN32 SILC Scheduler to the file
1341 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1344 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Do not handle JOIN notify in the server if the target client
1347 is not registered (idata->registered == FALSE). The affected
1348 file is silcd/packet_receive.c.
1350 * Update the nickrec->founder in event_cumode in the Irssi SILC
1351 client. Affected file irssi/src/silc/core/silc-channels.c.
1353 * Fixed the CUMODE_CHANGE notify handling in the server when
1354 server and router are announcing their clients on channels.
1355 Now the mode changes are saved and notified correctly. The
1356 affected file is /silcd/packet_receive.c.
1358 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1359 They really did not replace the cache entry in the ID Cache.
1360 Now they do that. Affected file silcd/idlist.c.
1362 * Fixed the KICK notify handling in the Irssi SILC client to
1363 update the channel records so that the kicked client does not
1364 appear to be on the channel. The affected file is
1365 irssi/src/silc/core/silc-channels.c.
1367 * Always update the conn->current_channel when executing command
1368 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1370 * Fixed the KILL notify handling in Irssi SILC client to remove
1371 the killed client on all channels.
1373 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1375 * Fixed the silc_parse_command_line to remove extra spaces
1376 from the start and end of the arguments. Affected file is
1377 lib/silcutil/silcutil.c.
1379 * Cancel and free any active protocol in the function
1380 silc_server_close_connection. Affected file silcd/server.c.
1382 * Cancel and free any active protocol in the function
1383 silc_client_close_connction. Affected file is
1384 lib/silcclient/client.c.
1386 * Do not execute the KILL command for clients that are in
1387 history (ie. they are not in the network). Affected file is
1390 * Fixed KILL notify handling, client does not crash anymore.
1391 Affected file irssi/src/silc/core/silc-channels.c.
1393 * Reduced the default packet buffer size from 2048 to 1024 in
1394 lib/silccore/silcpacket.c.
1396 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1397 counter to the SKE context that is incresed when the SKE library
1398 performs async operation outside the library. If the outside
1399 process frees the SKE context and FREED status will be set
1400 and the library will detect after the sync operation that the
1401 libary is freed. The affected files are
1402 lib/silcske/silcske[_status].[ch].
1404 * Resolve the client entry information in the function
1405 silc_client_channel_message to assure that NULL pointer is not
1406 passed as client entry to the application. */
1408 * Fixed the task timeout calculation to assure that there is
1409 never negative timeouts. The affected file is
1410 lib/silcutil/silcschedule.c.
1412 * Fixed the channel user mode notification sending in server.
1413 It was sent point-to-point to the router (or to server by router)
1414 but it needs to be destined to a channel. The routines now
1415 supports sending the channel user mode notifys to the channels
1416 when announcing clients and channels. Affected files are
1417 silcd/server.c and silcd/packet_receive.c.
1419 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1420 It did not actually replace the old channel entry in the cache.
1421 Affected file lib/silcclient/client_notify.c.
1423 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Fixed a possible crash in silc_packet_send_prepare. It now
1426 assures always that there is enough space in the buffer and
1427 at the tail area of the buffer (for MAC).
1429 Fixed the inbound buffer reallocation in silc_packet_read.
1430 It was old code and did not handle the reallocation correctly.
1433 The affected file is lib/silccore/silcpacket.c.
1435 * Fixed buffer overflow in silc_parse_nickname in the file
1436 lib/silcutil/silcutil.c.
1438 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * make install generates new server keys only if there is not
1443 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1446 Added check that if the NOREPLY is set then we will not send
1447 the away message. This avoids infinite loop of away messages
1448 if both clients are away. The affected file is
1449 lib/silcclient/client_prvmsg.c.
1451 * Fixed client crash if /NICK was given without arguments.
1452 Affected file lib/silcclient/command.c.
1454 * Server does not send the invite list in INVITE command back
1455 to the client if the list was not altered. Added this notion
1456 to the protocol spec as well. Affected file silcd/command.c.
1458 Fixed possible crash in INVITE command by checking the
1459 value of silc_server_get_client_route command.
1461 * Fixed the INVITE notify type handling. The arguments are now
1462 taken in correct order and client does not crash. The affected
1463 file is irssi/src/silc/core/silc-channels.c.
1465 Removed the "Inviting xxx to channel" message from the
1466 client library away and let the application handle it.
1467 Affected file lib/silcclient/command.c. Added that message
1468 to Irssi SILC client's message formats.
1470 * Fixed CMODE command crash in client. It now checks the
1471 amount of arguments correctly and does not crash. The affected
1472 file is lib/silcclient/command.c.
1474 * Do not create new channel automatically in silc_channels_join
1475 but check whether the channel by that name already exists.
1476 Affected file irssi/silc/core/silc-channels.c.
1478 * Do not send the SERVER_SIGNOFF to router if the disconnected
1479 entity was the router. Affected file silcd/server.c.
1481 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1482 SILC client as it was missing from there.
1484 Added the handling of the KICK notify to the Irssi SILC client
1485 as it was missing. Added "you have been kicked" message to
1486 Irssi SILC client's message modules formats.
1488 Added the handing of the KILL notify to the Irssi SILC client
1489 as it was missing. Added the kill message module formats
1492 The affected file is irssi/src/silc/core/silc-channels.c.
1494 * The router did not save the channel mode the server announced.
1495 Affected file silcd/packet_receive.c.
1497 * Fixed a possible crash in INFO command in server. If the
1498 server did not provide the server info it crashed. Affected
1499 file silcd/command.c.
1501 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Fixed the GETKEY command in the server to check also the
1504 global list. Otherwise the GETKEY would not work correctly
1505 in normal SILC server. Affected file silcd/command.c.
1507 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Fixed GETKEY crash, it crashed if the command did not succseed.
1511 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1514 is now real and not just an macro interface to GMP.
1516 Removed the entire GMP from the source tree and imported new
1517 NSS MPI library instead. Reason for removing GMP is that it is
1518 extremely large and compiles extremely slow. The NSS MPI
1519 is only a few files and compiles in less than 10 seconds.
1520 The speed is also about the same as GMP. The MPI is imported
1521 to lib/silcmath/mpi.
1523 If the system has GMP installed we will still use the GMP.
1524 If it is not then the NSS MPI will be compiled.
1526 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Merged a long nickname (127 characters long) crash bugfix from
1529 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1531 * Merged a freed memory reference bugfix from Irssi CVS tree.
1532 Affected file irssi/src/core/commands.c.
1534 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1536 * Added the server's public key sving and verification to the
1537 server when performing the SKE. This was missing and the
1538 remote server's (or router's) public key was accepted without
1539 checking whether we have it previously or trust it at all.
1540 Affected file silcd/protocol.c.
1542 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Check in the silc_server_timeout_remote if protocol is active
1545 and make sure that the protocol's final callback is called so
1546 that all memory if freed. Affected file silcd/server.c.
1548 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1550 * silc_server_whois_send_reply crashed the server if the nickname
1551 was 127 characters long. Affected file silcd/command.c.
1553 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Added sanity check to the silc_server_new_client. If the hostname
1556 is provided inside username then check that the provided hostname
1557 really is the same as the resolved one. If the hostname was not
1558 resolved then check it from the public key. Affected file is
1559 silcd/packet_receive.c.
1561 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1562 if the server disconnected us and the connection is not valid
1563 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1565 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1566 the library to the lib/silcutil/silcutil.[ch].
1568 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Close log file after open. Affected file
1571 lib/silcutil/silclog.c.
1573 * Check whether sock == NULL in silc_client_send_packet and return
1574 if it is. Affected file lib/silcclient/silcclient.c.
1576 * Check rec->entry == NULL in the Irssi SILC Client before
1577 sending the channel message. Affecte file is
1578 irssi/src/silc/core/silc-servers.c.
1580 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Merged a splitted window bugfix from Irssi CVS tree. The
1583 affected file is irssi/src/fe-text/textbuffer-view.c.
1585 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1586 It did not print nickname.
1588 * Improved the distributions system a bit.
1590 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1593 irssi/src/fe-text/gui-window.c.
1595 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1596 to in-active server. The affected file is
1597 irssi/src/silc/core/client_ops.c.
1599 * Resolve the client in USERS command reply if the entry does
1600 not have username resolved. The affected file is
1601 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1602 command to WHOIS command to really resolve stuff. The USERS
1603 is not used any more in any critical section so WHOIS can
1604 be used even though it might be slower than IDENTIFY.
1606 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1609 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1611 * Changed the protocol API a bit more consistent in the
1612 lib/silccore/silcprotocol.[ch].
1614 * Changed the following headers to ROBODoc format:
1616 lib/silccore/silcpayload.h
1617 lib/silccore/silcprotocol.h
1618 lib/silccore/silcsockconn.h
1620 All core library headers are now formatted.
1622 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Fixed a bug in Irssi SILC client; do not show that you are
1625 server/router operator if you really are not. Affected file is
1626 irssi/src/silc/core/client_ops.c.
1628 * Renamed silc_command_free_payload to silc_command_payload_free.
1629 Affected file lib/silccore/silccommand.h
1631 * Added silcmath.h to include the prototoypes of various routines
1632 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1635 * Changed the following headers to ROBODoc format:
1637 lib/silccore/silcchannel.h
1638 lib/silccore/silccommand.h
1639 lib/silccore/silcid.h
1640 lib/silccore/silcidcache.h
1641 lib/silccore/silcmode.h
1642 lib/silccore/silcnotify.h
1643 lib/silccore/silcpacket.h
1644 lib/silcmath/silcmath.h
1646 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1648 * Added checking to the server code not to start the server if
1649 ciphers and stuff are not configured properly. Affected files
1650 silcd/serverconfig.[h] and silcd/server.c.
1652 * Changed the layout of the header files of the public interfaces
1653 in the SILC libraries. The new layout supports ROBODoc
1654 documentation tool (and some others) so that it is easy to create
1655 a library reference manual. All the other headers and source
1656 code must still follow the CodingStyle document. Also source
1657 code must not include these ROBODoc stuffs, only the headers.
1658 Furthermore, all public interface headers must now be named
1659 by using `silc' prefix, example: silcapi.h, silccipher.h.
1660 Some files were renamed due to this. All the other headers
1661 must not be used as public interfaces. I will update the
1662 CodingStyle document later. Changed following headers, so far:
1664 lib/silcclient/silcapi.h
1665 lib/silccore/silcauth.h
1666 lib/silccore/silcprivate.h
1667 lib/silccrypt/silcdh.h
1669 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Removed silc_client_packet_send_flush from the client library
1674 as it is not needed. Affected file lib/silcclient/client.[ch].
1676 * Added printing of message of unresolved authentication method
1677 to the Irssi SILC client. Added it to the module formats.
1678 Removed the same message from the client library.
1680 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Added new distribution feature, DISTLABEL. Every distribution
1683 can define own preprocessor label that can be used in the
1684 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1685 file distributions, acconfig.h.pre and prepare.
1687 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Added Makefile.defines_int to include the actual definitions
1690 for Makefile.defines.in. Tested the new distribution system,
1691 created distributions and tested installation.
1693 * Added AWAY message printing to the Irssi SILC client. Added
1694 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1696 * Added SCONNECT command to call the SILC's CONNECT command.
1697 Cannot use CONNECT directly since Irssi uses that internally.
1698 Affected file irssi/src/silc/core/silc-servers.c.
1700 Added ACTION local command. It is same as ME command but takes
1701 the channel as mandatory argument.
1703 Rewrote some of the Irssi's help files to suite for SILC
1706 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Added Makefile.defines[.in] that should for now on be included
1709 in all Makefile.am file in the source tree. That file includes
1710 all common compilation definitions for SILC source tree.
1712 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Minor changes to the ./prepare script to change the package
1715 name according the distribution name to the configure.in.
1717 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Created new distribution system. Added file `distributions'
1720 that defines all the distributions that can be created out of
1721 the SILC source tree. The ./prepare script now reads that
1722 file to determine how to prepare the distributions. The
1723 first argument to the ./prepare is the name of the distribution
1724 and second is the version of the distribution. If given
1725 without arguments it creates the default (toolkit) distribution
1726 with the default version (defined in ./prepare).
1728 All Makefile.am files that are subject to the distributions
1729 are now named as Makefile.am.pre. These are ./Makefile.am
1730 and lib/Makefile.am. Others may be changed later.
1732 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Added invite list, ban list, some key management and connection
1735 error message printing to module formats in the Irssi SILC client.
1737 * Added new silc_client_set_away_message to set the away message
1738 that is back to the person who sent private message. The
1739 affected file lib/silcclient/silcapi.h and the
1740 lib/silcclient/client_prvmsg.c.
1742 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1744 * Fixed the private message sending in the Irssi SILC client,
1745 added local command KEY to the Irssi SILC client.
1747 Added key management and key agreement message formats to the
1748 irssi/src/fe-common/silc/module-formats.[ch].
1750 Added USERS (alias WHO) printing, server/router operator
1751 indication and LIST command printing to the module formats.
1753 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Fixed channel joining notify handling, cumode notify handling
1756 from Irssi SILC client.
1758 * Added SILC specific module-formats to the Irssi SILC client so
1759 that SILC specific message hilighting, colors etc is possible.
1760 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1762 Added channel mode, channel user mode, actions, notices,
1763 whois and whowas printing to the the module-formats.c.
1765 * Fixed a bug in channel deletion in the server. The channel
1766 is not left to the cache even if the channel founder auth mode
1767 is set when there are no users anymore on the channel. Affected
1768 file silcd/server.c.
1770 * The silc_net_localhost now resolves the entire hostname including
1771 the domain name. Affected file lib/silcutil/silcnet.c.
1773 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Changed the ask_passphrase client operation to be ascynchronous.
1776 It has now a completion callback and a context that the
1777 application must call after it has got the passphrase from
1778 the user. Affected files lib/silcclient/silcapi.h,
1779 lib/silcclient/protocol.c, lib/silcclient/command.c and
1782 Added SilcAskPassphrase callback that the application calls
1783 to deliver the passphrase to the library.
1785 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1786 The public key verification and especially a certificate
1787 verification is asynchronous procedure.
1789 Added new SILC_SKE_STATUS_PENDING status to indicate the
1790 request is pending and a callback will be called to finalize
1793 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1794 indicate that remote end did not send its public key (or
1795 certificate), even though we require it. Added check for this
1796 condition in the SKE. This was a security bug, now fixed.
1798 Defined new SilcSKEVerifyCbCompletion callback that is called
1799 when the verification process is completed.
1801 The affected files lib/silcske/silcske_status.h and
1802 lib/silcske/silcske.[ch].
1804 * Changed the verify_public_key client operation to be async
1805 as well. Defined SilcVerifyPublicKey callback that is used to
1806 indicate the success of the public key verification process.
1808 Changed the server and client to use the new async client
1811 * Changed the Irssi SILC client's internal scheduler to be called
1812 twice as many times as it used to be. As a result the client
1813 should be a bit faster now. Affected file is
1814 irssi/src/silc/core/silc-core.c.
1816 * Added support to Irssi SILC client of asynchronous public key
1817 verification and passphrase inquiry. Affected file is
1818 irssi/src/silc/core/silc-core.c.
1820 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1822 * Do not say "You have left channel %s" in client library.
1823 Moved it to the application. Affected files are
1824 lib/silcclient/command.c and silc/client_ops.c.
1826 * Fixed silc_client_get_clients. Command context was not
1827 duplicated and was freed memory in the callback. Affected
1828 file lib/silcclient/idlist.c.
1830 * Do not say "you are now talking..." on JOIN command in the
1831 client library. The appliation must handle it.
1833 * Do not say ".. changed topic to" in command reply in the
1834 client libary. The application must handle it.
1836 * Fixed TOPIC command sending in the client library.
1838 * Fixed a memory leak in silc_client_command_free in the file
1839 lib/silcclient/command.c.
1841 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Imported a modified version of Irssi client to the source tree.
1844 The Irssi will be used to create a new client called
1845 Irssi SILC. Imported to irssi/.
1847 Added silc_core_init_finish function to the Irssi. Affected
1848 file irssi/configure.in.
1850 A lot changes in the Makefile.ams around the irssi tree.
1852 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * Do not rehash if the new size is same as the old size of the
1855 hash table, in the silc_hash_table_rehash*. The affected file
1856 lib/silcutil/silchashtable.c.
1858 * Replaced hash_table_del_by_context calls from the server
1859 (when channel->user_list and client->channels) to the
1860 hash_table_del as it is sufficient and faster.
1862 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Added silc_hash_table_list, silc_hash_table_get and the
1865 SilcHashTableList structure to provide an alternative way to
1866 traverse the hash table. The affected files are
1867 lib/silcutil/silchashtable.[ch].
1869 * Changed the server's idlist routines to use the hash table
1870 routines to optimize the code.
1872 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Replaced the client entry's `channel' list and channel entry's
1875 `user_list' list to hash tables for optimized lookup. Changed
1876 the code to use the hash table interface around the code.
1877 Affected file lib/silcd/idlist.[ch].
1879 * Added `auto_rehash' boolean argument to the function
1880 silc_hash_table_alloc to indicate whether the hash table should
1881 auto-rehash when it thinks is appropriate time. It will
1882 increase the hash table size if the there is twice as much
1883 entries in the table than the size of the table, and will
1884 decrease the size if there are twice as less entries than
1885 the size of the table.
1887 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1891 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * silc_idcache_purge_by_context deletes the entry now by context
1894 as it is supposed to do. Affected file lib/silccore/idcache.c.
1896 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1897 client is not anymore valid (WHOWAS givens the info) and not
1898 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1900 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Removed the `data' and `data_len' arguments from the ID Cache
1903 interfaces and added `name' argument. ID Cache does not handle
1904 anymore the binary data only a names associated with given ID.
1906 * When hashing a Client ID with silc_hash_id the entire ID is
1907 not hashed anymore, instead only the hash of the Client ID is
1908 hashed. This way we can access the Client ID from the cache
1909 with Client ID but with the hash of the ID (which is a hash of
1910 the nickname) as well without any difference in performance.
1912 Added also silc_idcache_find_by_id_one_ext to do one on one
1913 searching when we have the actual ID. Added also function
1914 silc_hash_client_id_compare. The affected files are
1915 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1917 * When hashing the name associated with a ID it is always done
1918 in lowercase. This way we can access the cache without worrying
1919 about case-sensitivity, even though, for example nicknames are
1922 * Fixed a bug in server with channel message sending. It put
1923 wrong ID type as destination ID. The affected file
1924 silcd/packet_send.c.
1926 * silc_idcache_del_by_context now deletes from all hash tables
1927 by context. Affected file lib/silccore/idcache.c.
1929 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1931 * Changed the client library to use the new ID Cache interface.
1932 Changes around the source tree.
1934 * Added silc_hash_table_rehash_ext to rehash with specific
1935 hash function. Affected file lib/silcutil/silchashtable.[ch].
1937 * Added silc_hash_string_compare to compare two strings in the
1938 hash table. Affected file lib/silcutil/silcutil.[ch].
1940 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Added new function silc_idcache_del_by_context into the
1943 lib/silccore/idcache.[ch].
1945 * Changed the server's ID list routines to use the new ID Cache
1946 interface. Changes around the source tree.
1948 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added silc_hash_table_del[_by_context]_ext functions in to the
1951 lib/silcutil/silchashtable.[ch].
1953 Removed silc_hash_table_find_all* routines and added new
1954 silc_hash_table_find_foreach to replace them.
1956 Added silc_hash_table_replace_ext function as extended
1957 replacing function. Separated the simple hash table interface
1958 from the extended hash table interface in the file
1959 lib/silcutil/silchashtable.h.
1961 * Fixed minor bugs and changed it to use some of the new
1962 hash table functions in lib/silccore/idcache.c
1964 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1966 * Added new function silc_hash_table_find_all to return all keys
1967 in the hash table by the specified key. As the hash table is
1968 collision resistant it also makes it possible to have several
1969 duplicate keys in the hash table. This function may be used to
1970 find all of the keys from the hash.
1972 Added user_context arguments to the SilcHashFunction,
1973 SilcHashCompare and SilcHashDestructor to deliver user specified
1976 Added new fuctions silc_hash_table_find[_all]_ext to do
1977 extended lookup with specified hash and compare functions and
1978 specified user contexts.
1980 Added new function silc_hash_table_add_ext to add the key
1981 with specified hash function and user context.
1983 Added new function silc_hash_table_foreach to traverse all
1984 entrys in the hash table. Added SilcHashForeach callback
1987 Added new function silc_hash_table_del_by_context to delete
1988 the entry only if the context associated with the key matches.
1990 Affected files are lib/silcutil/silchashtable.[ch].
1992 * Removed silc_hash_[server/client/channel]_id and added just
1993 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1994 silc_hash_id_compare to compare two ID's using as the hash table
1995 comparison function. Added also silc_hash_data to hash
1996 binary data and silc_hash_data_compare to compare it.
1998 * Removed silc_idlist_find_client_by_hash as it is not needed
1999 anymore. Affected file silcd/idlist.[ch].
2001 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2002 to use internally the SilcHashTable. The new ID Cache is a lot
2003 faster than the old one. Some of the ID Cache interface was also
2004 rewritten and obsolete and stupid functions were removed.
2006 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Added entry_count field to the SilcHashTable to keep the number
2009 of the entries in the table. Implemented the function
2010 silc_hash_table_rehash. Added new function
2011 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2013 Fixed a minor bug in silc_hash_table_free.
2015 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2016 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2017 into the lib/silcutil/silcutil.[ch].
2019 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Implemented a collision resistant hash table into the
2022 lib/silcutil/silchashtable[ch]. See the header and the source
2023 for the SilcHashTable API.
2025 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Merged dotconf version 1.0.2 into lib/dotconf.
2029 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Do not compile anything in lib/silcsim/* if the SIM support
2032 is not enabled. The tree should now compile without problems
2035 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Compiled the SILC under cygwin. Compiled and tested briefly
2038 without problems. More tests needed. The SIMs didn't compile
2041 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2043 * Fixed possible crash in silc_get_username in the
2044 lib/silcutil/silcutil.c.
2046 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * Fixed a va_arg in silc/client_ops.c.
2050 * Oops, RC5 routines were named AES and caused some problems
2051 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2053 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Added new SilcIDIP structure into the lib/silccore/id.h and
2056 replaced the old `ip' fields from all SILC ID's to that type.
2057 This is a step towards IPv6 support.
2059 The silc_id_get_len takes now the ID as an extra argument.
2060 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2061 both IPv4 and IPv6 based ID's.
2063 The affected files are lib/silccore/id.[ch] and other files
2064 around the tree using these routines.
2066 * Removed the ID length arguments in server from various
2067 silc_server_send_notify_* routines -> they are not needed
2070 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2072 * Fixed memory leak in silc_encode_pem_file in the file
2073 lib/silcutil/silcutil.c.
2075 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Check minor version as well in the SKE. Affected files are
2078 silcd/protocol.c and lib/silcclient/protocol.c.
2080 * Added --identifier option to the server so that an identifier
2081 can be when creating the public key for the server. Affected
2082 file is silcd/silcd.c.
2084 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2085 lib/silccrypt/silcpkcs.c.
2087 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2089 * Register default ciphers and stuff when using -C option with
2090 the server. Affected file sildc/silcd.c.
2092 * Put back the servers public key filename format, it is better
2093 than the new one. For now, the client keys are saved with the
2094 new filename format. The affected file silc/client_ops.c.
2096 * Implemented the Cipher API for the rest of the ciphers that
2097 did not implement it or implemented it the wrong way.
2099 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Register default ciphers and stuff when using the -S option
2102 in the client. Affected file silc/silc.c. Same also when
2103 creating new key pair with -C option.
2105 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Fixed the silc_verify_public_key client operation function to
2108 save the public keys differently. The fingerprint is now
2109 used as filename and not the hostname. This way also the
2110 client keys are saved uniquely and not with hostnames. The
2111 affected file is silc/client_ops.c.
2113 * Trimmed the silc_hash_fingerprint function to remove extra
2114 whitespaces from the end of the fingerprint. The affected
2115 file is lib/silccrypt/silchash.c.
2119 * Added silc_cipher_register_default function to register all
2120 default ciphers. It can be used when configuration files
2121 does not exist and the application does not want any specific
2122 ciphers in any specific order.
2124 The SilcDList is now used as silc_cipher_list dynamically
2125 allocated cipher list. Removed the static list all together
2126 and now all ciphers must be allocated to the dynamic list.
2127 The silc_cipher_alloc routine was changed to check only the
2130 All silc_cipher_* routines that used to return int returns
2133 The affected files lib/silccrypt/silccrypt.[ch].
2135 * The same thing was done to silc_hash_* as for silc_cipher_*
2136 routines. Affected files lib/silccrypt/silchash.[ch].
2138 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2139 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2140 Added also silc_pkcs_[un]register[_default] functions.
2141 Removed the data_context from the PKCS API.
2143 * Added silc_hmac_register_default function to register default
2144 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2145 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2146 to unregister all hmacs at once.
2148 * Register the default ciphers, hash functions, PKCSs and HMACs
2149 if client's configuration file does not exist. The affected
2152 * The client did not load the hash functions from the SIM
2153 modules at all. Added support for this. Affected file is
2154 silc/clientconfig.c.
2156 * When decoding public key with silc_pkcs_public_key_decode, check
2157 the supported algorithm only if PKCS are registered. Affected
2158 file lib/silccrypt/silcpkcs.c. The same was done with the
2159 silc_pkcs_private_key_decode.
2161 * Fixed the SILC List routines to keep the list always in order.
2162 It used to change the list's order when traversing the list but
2163 not it preserves the order. Affected file lib/trq/silclist.h.
2165 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Added the client library to use the SilcSocketConnection's
2168 reference counter (by silc_socket_dup) to prevent the bug that
2169 the socket object may be freed underneath async operation.
2171 * The name resolv library checking fixes in the configure.in.pre.
2174 * Created new version of the protocol drafts for future
2175 development. The -03 drafts are the ones that will be changed
2176 in the trunk now and the -02 will remain as they are.
2178 * Send list of CUMODE notifys to the router when announcing
2179 the channel users to the router. Affected file silcd/server.c.
2180 If the router receiving channel founder CUMODE for a channel
2181 that already has channel founder it will send CUMODE notify
2182 to the sender to remove the channel founder rights from the
2183 announced client. Affected file silcd/packet_receive.c.
2185 * The CUMODE notify may now use Server ID as well as the entity
2186 who changes the mode. Updated protocool specs.
2188 * Updated INSTALL and README files.
2190 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * New web pages in the http://silc.pspt.fi. The pages was
2197 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Implemented the [DenyConnectin] config section in the server.
2200 Added silc_server_config_denied_conn to check whether incoming
2201 connection is denied. Affected file silcd/serverconfig.[ch].
2203 * Do not check the ports when checking the incoming configuration
2204 data if the port is 0, meaning any. Affected file is
2205 silcd/serverconfig.c.
2207 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Fixed buffer overflow in silc_string_compare in the file
2210 lib/silcutil/silcutil.c.
2212 * Fixed double free in silc_server_command_leave in the file
2215 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Fixed the version checking in the server. Affected file is
2220 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Fixed the configuration data fetching when accepting new
2223 connections in the server. Affected file silcd/server.c.
2225 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Added `sender_entry' argument to the function
2228 silc_server_packet_relay_to_channel so that we can check
2229 whether some destination actually belongs to the same route
2230 the sender belongs (ie, we must not resend the packet to the
2231 sender). Affected file silcd/packet_send.[ch].
2233 * Added `servername' field to the SilcClientEntry in the server
2234 to hold the name of the server where client is from. Affected
2235 file is silcd/idlist.h.
2237 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Moved the channel message encrypting in the router betwen
2240 router connections from silc_server_channel_message to the
2241 silc_server_packet_relay_to_channel since we want to check
2242 whether we have anybody channel before encrypting anything.
2243 Affected files silcd/packet_[receive/send].c.
2245 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Fixed the [AdminConnection] server config section to support
2248 multiple entries. Affected file silcd/serverconfig.c.
2250 * Added support into the server to check the validity of the
2251 incoming connection before executing any KE or authentication
2254 * The connection configuration is now saved to the KE and
2255 connection auth protocol contexts and not fetched anymore in
2256 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2258 * The local hosts listenning address and port is also resolved
2259 now when starting the server. We want to have the socket object
2260 to include the real address and port for the listener. Added
2261 new function silc_net_check_local_by_sock into the files
2262 lib/silcutil/silcnet.[ch].
2264 * Fixed a broadcast bug in server -> do not broadcast if we
2267 * Fixed a routing bug. Do not route broadcast packets ever.
2268 Broadcast packets must be processed always and not routed since
2269 they may be destined to some other host than yourself and thus
2270 would get routed without no good reason. Affected file is
2273 * Added function silc_server_config_is_primary_route to check
2274 whether primary router connection has been configured (a router
2275 configuration that we are initiating). If there is not, we
2276 will assume that there is only two routers in the SILC network
2277 and we will use the incoming router connection as our primary
2278 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2280 * Changed the order of the broadcasting. Broadcast _after_ the
2281 packet has been processed not before. Affected file is
2284 * Fixed a [ClientConnection] parsing bug. The port was never
2285 parsed correctly thus resulting to port 0. Affected file
2286 silcd/serverconfig.c.
2288 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2289 argument and did not set the broadcast packet flag. Affected
2290 file silcd/packet_send.c. Fixed same bug in the function
2291 silc_server_send_notify as well.
2293 * If we receive NEW_ID packet for our own ID in the server, ignore
2296 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Removed the nickname from the Private Message Payload.
2301 Updated the code and the protocol specs.
2303 * Updated protocol specs for submitting to the IETF.
2305 * Tweaked the Random Number Generator a bit. Affected file
2306 lib/silccrypt/silcrng.c. Exported a new function
2307 silc_rng_[global]_add_noise which can be used to add more
2310 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Do not parse packets with different timeout when protocol
2313 is active -> may cause problem with rekey. Affected file
2316 * When server receives signoff notify it must not create
2317 new channel key if the client is on any channels since the
2318 sender of the signoff notify will create it.
2320 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added printing of error messages during SKE protocol from the
2323 failure packet sent by server during SKE. Affected file
2326 * Removed the client's failure_callback handling with timeout
2327 and handle it immediately when received.
2329 * The SKE library returned wrong type in SUCCESS and FAILURE
2330 packets. They must be 32 bit MSB not 16 bit MSB.
2332 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Ok, rewrote the logic of the re-key and now it seems to work.
2335 I tested it on high traffic with frequent re-keys without
2336 problems. Added hmac_receive (and renamed hmac to hmac_send)
2337 in SilcClientConnection in lib/silcclient/client.h and
2338 in SilcIDListData in silcd/idlist.h. Also, removed the
2339 SilcPacketParserContext's cipher and hmac fields as they are
2340 not needed anymore and actually caused some problems when
2341 the ciphers and hmac's changed underneath the packet parser.
2343 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * If re-key protocol is active then process the incoming packets
2346 synchronously since we must assure that icoming packets encrypted
2347 with the old key is processed before the new keys is set to
2348 use. This is true other packets than for REKEY packets.
2349 Affected file silcd/server.c. The same was done to client library
2350 as well, affected file lib/silcclient/client.c.
2352 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Fixed bug in client and server to accept the force send if
2355 the packet is send from silc_[server/client]_packet_process
2356 function. Otherwise the packets are never delivered, oops.
2358 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2360 * Disable force sending of packets when REKEY protocol is active.
2361 We must assure that no packet is sent directly when rekey is
2362 performed. All packets must be sent through packet queue.
2363 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2364 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2365 function is silc_[server/client]_packet_send_real to check
2368 * Replaced the SIM paths from example config files to
2369 /usr/local/modules. Also, make install creates now
2370 /usr/local/silc/logs directory to hold all the SILC server
2373 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Made the configure.in.pre work on Solaris. Patch by salo.
2377 * Made all ciphers compatible with non-x86 machines. Defined
2378 CBC mode macros into lib/silccrypt/ciphers_def.h.
2380 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2382 * Fixed the make install.
2384 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * When MAC computation fails the silc_packet_decrypt returned 0
2387 even though it was supposed to return -1. Fixed this. The
2388 affected file is lib/silccore/silcpacket.c.
2390 * Do not replace the config files in /etc/silc (in make install)
2391 if they already exist. Affected file ./Makefile.am.
2393 * Do not send re-key packets immediately but through packet queue.
2394 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2396 * Changed silc_net_check_host_by_sock to return FALSE if the
2397 IP/DNS could not be resolved. Though, it returns the IP address
2398 now even if it could not resolve it (but returns also FALSE).
2399 Affected file lib/silcutil/silcnet.[ch].
2401 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Added silc_pkcs_decode_identifier to decode the public key's
2404 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2405 Added also silc_pkcs_free_identifier. Added also new context
2406 SilcPublicKeyIdentifier.
2408 * Added -S option to the silc client. It is used to dump the
2409 contents of the specified public key file.
2411 * Changed the PKCS api to return the public key length when
2412 setting the public key.
2414 * Fixed a fatal bug in the public and private key file loading.
2415 Affected file lib/silccrypt/silcpkcs.c.
2417 * Execute the packet parsing for client with zero (0) timeout
2418 if the protocol is active. Affected file silcd/server.c.
2420 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Made the key generation options to the silcd program. Added
2423 -C option, equivalent to client's option.
2425 * Added new [ServerKeys] config section to the server. It
2426 configures the server's public and private key.
2428 * Defined generic Public Key Payload into the protocol
2429 specification to send specific type of public keys and
2432 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2433 public key or certificate.
2435 * Implemented the GETKEY command to the server and to the
2436 client library and on user interface.
2438 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Made preliminary `make install' work.
2442 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Added SilcServerRekey context into silcd/idlist.h.
2446 * Added the PFS support as defined in the specification to the
2447 SKE protocol. Affected files lib/silcske/*.c.
2449 * Added `ske_group' field to the SilcServerRekey context to hold
2450 the number of the SKE group that is used with PFS in re-key.
2451 Affected file silcd/idlist.h.
2453 * Added PFS re-key support to the server. Affected file is
2456 * Added silc_protocol_cancel to cancel execution of the next
2457 state of the protocol. Affected file is
2458 lib/silccore/silcprotocol.[ch].
2460 * Added the re-key support with and without PFS to the client
2461 library. Re-key is performed once in an hour, by default.
2463 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2464 Added silc_client_rekey_callback and silc_client_rekey_final.
2465 Affected files are lib/silcclient/protocol.[ch] and
2466 lib/silcclient/client.[ch].
2468 * Removed the `hmac_key' and `hmac_key_len' fields from the
2469 SilcClientConnection structure; not needed. Affected file is
2470 lib/silcclient/client.h.
2474 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Do not ask whether user wants to use the negotiated private key
2477 for private messages, just use it. Affected file is
2478 silc/local_command.c.
2480 * Added `send_enc_key' and `enc_key_len' fields to the
2481 SilcIDListData structure since they are needed in the re-key
2482 phase. Affected file is silcd/idlist.[ch].
2484 * Implemented the simple re-key protocol into the server.
2485 Affected files silcd/server.c and silcd/protocol.[ch]. The
2486 re-key will be performed once in an hour, by default.
2488 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2489 Added silc_server_rekey, silc_server_rekey_callback and
2490 silc_server_rekey_final.
2492 * Removed Tunneled flag from the protocol. Updated the code
2493 and the specifications.
2495 * Adde `pfs' field to the SilcIDListData to indicate whether
2496 the PFS is to be performed in the re-key. Affected file is
2499 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2502 int64 of at least the xintXX size. If void * is less that 4
2503 bytes uint32 * will be used. Defined bool as boolean.
2505 * Changed _ALL_ unsigned long and unsigned int to uint32,
2506 unsgined short to uint16 in the source tree.
2508 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2509 not handle clients that has entry->data.registered == FALSE.
2510 They are not in the network anymore. Affected file is
2513 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Implemented the sending of the SERVER_SIGNOFF notify in the
2516 server. Affected file is silcd/server.c.
2518 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2519 Added also silc_notify_payload_encode_args into the
2520 lib/silccore/silcnotify.[ch].
2522 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2523 Affected file silcd/packet_receive.c.
2525 * Implemented the SERVER_SIGNOFF notify handling in the client
2526 library. Affected file lib/silcclient/client_notify.c. Also,
2527 implemnted the printing of the SERVER_SIGNOFF info to the
2528 application. Affected file silc/client_ops.c.
2530 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2531 if the deleting was successful. Affected file silcd/idlist.[ch].
2533 * Added support for public key authentication in the connection
2534 authentication protocol in the client library. Affected file
2535 lib/silcclient/protocol.c.
2537 * Changed the server's silc_idlist_get_clients_by_* interface
2538 to support already allocated array so that new entries may be
2539 added to pre-allocated array. Affected file silcd/idlist.[ch].
2540 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2541 and command replies.
2543 * All command reply functions in the server now calls the
2544 pending command callback even if error occured. This way the
2545 error will be delivered to the client as well. Affected files
2546 silcd/command.c and silcd/command_reply.c.
2548 * Fixed INFO command to return local server's info if no server
2549 was provided. Affected file lib/silcclient/command.c.
2551 * Removed RESTART command for good. Updated the code and the
2554 * Rewrote parts of the task system. It is a bit simpler now.
2555 Removed unsued task priorities. The affected files are
2556 lib/silcutil/silctask.[ch].
2558 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Moved the USERS printing from the library to the application.
2561 Affected files lib/silcclient/command.c and silc/client_ops.c.
2563 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Added channel key re-key support. The re-key is perfomed
2568 only by the router and is done once in an hour. Added `rekey'
2569 field to the SilcChannelEntry in the server. Affected files
2570 silcd/server.c and silcd/idlist.h.
2572 * Added silc_task_unregister_by_context into the file
2573 lib/silcutil/silctask.[ch].
2575 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Added SILC_UMODE_GONE mode to indicate when the client is not
2578 present in the SILC network. Added also support to the local
2579 command AWAY that will set this mode. Added support of showing
2580 "xxx is gone" in WHOIS command. The USERS command shows the
2581 gone status as well.
2583 * Fixed setting server and router operator privileges in the
2584 server's UMODE command. Affected file silcd/command.c.
2586 * Merged the SKE KE1 and KE2 payloads into one payload. The
2587 new KE payload is equivalent to the old KE2 payload.
2589 Cleaned up the SKE Start Payload parsing. It now uses the
2590 simple buffer unformatting to do the parsing. A lot faster
2593 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2594 to the SKE that is used to indicate whether both of the SKE
2595 parties should perform authentication. By default only the
2596 responder performs authentication. By setting this flag also
2597 the initiator must do authentication. By default it is unset
2598 since in normal SKE case, client to server connection, only
2599 the responder should do authentication. When doing SKE between
2600 two clients both should perform authentication. Updated the
2601 code and the protocol specs.
2603 * A little fix to IDENTIFY command in the server. Search the
2604 client first by hash not nickname. Affected file is
2607 * Fixed the silc_client_close_connection to support closing
2608 the client to client connections wihtout deleting too much
2609 data. Affected file lib/silcclient/client.c.
2611 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2612 are received if protocol used to be active but is not anymore
2613 the application would crash due to NULL pointer dereference.
2614 Affected files silcd/server.c and lib/silcclient/client.c.
2616 * Added `hash' field to the SilcClientConnection to include
2617 the hash function negotiated in the SKE protocol.
2619 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2620 to set the channel founder authentication data. A client can
2621 claim the founder rights later by providing the authentication
2622 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2623 This way the channel founder can regain the channel founder
2624 privileges even it is left the channel. This works only on
2625 local server and the client must be connected to the same
2626 server to be able to regain the founder rights. Updated the
2627 protocol specs accordingly.
2629 Added support to the CMODE command in the client to set the
2630 founder auth data. Read the README to see how to set it.
2632 Added support to the CUMODE command to claim the founder
2633 rights. Read the README to see how to do it.
2635 Added support for the founder authentication to the Channel
2636 Entry in the server. Affected file silcd/idlist.h.
2638 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2639 server's CMODE command. Affected file silcd/command.c.
2641 * Added the following new functions into lib/silccore/silcauth.[ch]:
2642 silc_auth_get_method and silc_auth_get_data.
2644 * The server now saves the remote hosts public key to the
2645 SilcIDListData pointer. Affected file silcd/protocol.c.
2647 * The normal server now does not remove the channel entry from
2648 the cache if the founder authentication data is set. It used
2649 to remove it if the founder was the last one on the channel on
2650 the server and left the channel. The auth data is saved and
2651 if the channel is re-joined later the old entry is used with
2652 the old auth data. Affected files silcd/command_reply.c and
2655 * Removed the `pkcs' field from the SilcIDListData structure
2656 in the server; it is not used. Affected file silcd/idlist.h.
2658 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Fixed packet processing on slow links. Partial packets were
2661 never re-processed because the incoming data buffer was cleared
2662 by the application. Application must not directly clear the
2663 sock->inbuf, the packet processing routines handle it. Fixed
2664 this in client library and in server.
2666 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Fixed the WHOIS and IDENTIFY send reply function to really
2669 check whether to send list or just one entry. Affected file
2672 * Cleaned up the LEAVE command's channel key distribution. The
2673 affected file silcd/command.c.
2675 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2676 can enforce the channel mode as well. In that case the ID
2677 includes the ID of the server. The code now enforces the
2678 mode change if the router have different mode than the server.
2680 * The notify client operation with CMODE_CHANGE notify can now
2681 return NULL client_entry pointer if the CMODE was not changed
2682 by client. Application must check for this.
2684 * Added <Server ID> argument to INFO command to support server
2685 info fetching by Server ID.

2688 packets of channel users of the specified channel. Affected
2689 file silcd/server.[ch].
2691 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2692 was freed underneath the ID Cache.
2694 * Re-announce clients when the server received CHANNEL_CHANGE
2695 notify from the router. Affected file silcd/packet_send.c.
2697 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2700 crashed since it did not handle the fact that there is no cipher
2701 called "3" and didn't check the error condition. Now fixed.
2703 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2704 flag. It can be used to send message requests.
2706 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Implemented the RESTART command in the client.
2710 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2711 notice type messages. Added notice printing to the user
2714 * The channel keys are not re-generated if the channel's mode
2715 is PRIVKEY, ie private key on the channel exists. Affected
2716 files silcd/server.c and silcd/command.c.
2718 * Fixed a little bug in channel message delivery when channel
2719 private keys are set in the server. Affected file is
2720 silcd/packet_send.c.
2722 * Changed the setting on channel->on_channel = TRUE from the
2723 silc_client_save_channel_key to the JOIN command reply. The
2724 key payload is not received if the private channel key is set.
2725 Affected file lib/silcclient/command_reply.c and the
2726 lib/silcclient/client_channel.c.
2728 * When the CMODE_CHANGE notify is sent and the channel private
2729 key mode is removed the channel key must be re-generated in
2730 other cells as well. Added this support for the router in the
2731 silcd/packet_receive.c.
2733 * Added new local command NOTICE to send notice message on
2734 channel. Affected file silc/local_command.[ch].
2736 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Added new local command ME to the client. It is used to send
2739 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2740 some action. Affected file silc/local_command.[ch].
2742 * Changed channel_message and private_message client operations
2743 to deliver the message flags to the application. Added also
2744 the `flags' arguments to the silc_client_send_channel_message
2745 and silc_client_send_private_message functions. Affected file
2748 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Redefined the Private Message Payload to support private message
2751 keys and to support the new private message flags. Updated
2752 the protocol specs. Flags makes it possible to have for example
2753 CTCP style messages.
2755 * Added new type SilcPrivateMessagePayload and defined an API
2756 for it in the lib/silcclient/silcprivate.[ch].
2758 * Tested private message private keys successfully. Tested the
2759 private message key set, unset and list commands with the new
2762 * Redefined the Channel Message Payload to include the channel
2763 message flags (equal with private message flags) to support
2764 for example CTCP style messages.
2766 * Defined some of the message (for channel and private message)
2767 flags. Updated the protocol specs and added the flags to the
2768 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2770 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Added SilcKeyAgreementStatus type to the key agreement routines
2773 to indicate the current status and error if one occured.
2774 The status types are defined in the lib/silcclient/silcapi.h.
2776 * Added new local command KEY that is used to set and unset private
2777 keys for channels, set and unset private keys for private messages
2778 with remote clients and to send key agreement requests and
2779 negotiate the key agreement protocol with remote client. The
2780 key agreement is supported only to negotiate private message keys,
2781 it currently cannot be used to negotiate private keys for channels,
2782 as it is not convenient for that purpose.
2784 * Fixed a minor pending callback setting bug in the function
2785 silc_client_get_client_by_id_resolve, now the function works.
2786 Affected file lib/silcclient/idlist.c.
2788 * Added function silc_net_get_local_port to get local bound
2789 port by socket. Added to lib/silcutil/silcnet.[ch].
2791 * Added `sockets' and `sockets_count' fields to the SilcClient
2792 object. They hold the sockets of the listenning sockets in
2793 the client. Listenning sockets may be for example the key
2794 agreement server. Affected file lib/silcclient/client.[ch].
2795 Added functions the silc_client_add_socket and the
2796 silc_client_del_socket. They are exported to the application
2799 * Added ~./silc/clientkeys to support other client's public keys.
2801 * Renamed verify_server_key client operation to verify_public_key
2802 and added one argument to indicate the type of the connection
2803 (server, client etc.).
2805 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Added silc_server_connection_auth_request to handle the
2808 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2809 silcd/packet_receive.[ch].
2811 * Added silc_server_send_connection_auth_request into the
2812 silcd/packet_send.c to send the connection auth request packet.
2814 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2817 * Fixed the public key authentication in responder side in the
2818 server. The `auth_data' pointer includes the SilcPublicKey
2819 not the path to the public key. Affected file silcd/protocol.c.
2821 * Implemented the public key authentication in the initiator side
2822 in the server. Affected file silcd/protocol.c.
2824 * Removed the [RedirectClient] config section from the server
2825 configuration. Is not needed and I don't want to implement it.
2827 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Cleaned up the CMODE command in the server. It now works
2830 correctly and supports all the modes defined in the protocol.
2831 Affected file is silcd/command.c.
2833 * Added `hmac_name' field to the SilcChannelEntry in the server
2834 to hold the default HMAC of the channel. It can be set when
2835 creating the channel (with JOIN command). Affected files
2838 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2839 type to indicate the change of the current cipher and hmac
2840 on the channel. Client can safely ignore the <cipher> argument
2841 (if it chooses to do so) since the CHANNEL_KEY packet will
2842 force the channel key change anyway. The <hmac> argument is
2843 important since the client is responsible of setting the new
2844 HMAC and the hmac key into use.
2846 * Fixed the CMODE command in the client library as well.
2848 * Tested CMODE command in router environment successfully.
2850 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Show the version of the remote client (or server) when connecting
2853 to the server. It is logged to the log file. Affected file
2854 is silcd/protocol.c.
2856 * Fixed the KILLED notify handling in the client library. The
2857 client must be removed from all channels when receiving the
2860 Also, do not remove the client entry when giving the KILL
2861 command but when the KILLED notify is received.
2863 * Removed silc_idlist_find_client_by_nickname from the server.
2864 Not needed anymore. Affected files silcd/idlist.[ch].
2866 * Implemented the CHANNEL_CHANGE notify type handling to the
2867 server. Affected file silcd/server.c.
2871 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Added silc_server_send_notify_invite to send the INVITE
2874 notify between routers.
2876 * Implemented the INVITE command correctly to the server.
2878 * Implemented the INVITE notify type handling in the server.
2880 * Implemented the INVITE command to the client library and on the
2883 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * Added function silc_server_get_client_resolve to find the
2886 client entry by ID from all ID lists and then resolve it
2887 (using WHOIS) if it cannot be found. Affected file is
2890 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Implemented the BAN command to the client library.
2894 * The JOIN command in the server now checks the invite list
2897 * Changed the silc_command_reply_payload_encode_va and the
2898 silc_command_payload_encode_va to support that if argument is
2899 NULL it ignores and checks the next argument. Affected file
2900 lib/silccore/silccommand.c.
2902 * Added silc_server_send_notify_ban to send the BAN notify
2903 type between routers.
2905 * Chaned the silc_notify_payload_encode to support that if
2906 argument is NULL it ignores and checks the next argument.
2907 Affected file lib/silccore/silcnotify.c.
2909 * Tested ban lists in router environment successfully.
2911 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * Implemented BAN command to the server, in silcd/command.[ch].
2915 * Removed the BAN and INVITE_LIST modes from the CMODE command
2918 * Added function silc_string_match to regex match two strings.
2919 Affected files lib/silcutil/silcutil.[ch].
2921 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Redefined parts of the SilcChannelEntry in the server to support
2924 the new ban and invite lists.
2926 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Redefined the INVITE command. The same command can be used to
2929 invite individuals to the channel but also to manage the invite
2930 list of the channel (to add to and remove from the invite list).
2931 Updated the protocol specs.
2933 * Added new command SILC_COMMAND_BAN that can be used to manage
2934 the ban list of the channel. Updated the protocol specs.
2936 * Removed the channel modes: the SILC_CMODE_BAN and the
2937 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2938 in the CMODE command. The equivalent features are now available
2939 using INVITE and BAN commands. Updated the protocol specs.
2941 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2942 in the network about change in the current ban list. The notify
2943 type is not used by the client.
2945 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2946 support the invite lists.
2948 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Added new function silc_string_regexify that converts string
2951 including wildcard characters into regex string that can
2952 be used by the GNU regex library. Added into the file
2953 lib/silcutil/silcutil.[ch].
2955 Added silc_string_regex_combine to combine to regex strings
2956 into one so that they can be used as one regex string by
2957 the GNU regex library. Added into the file
2958 lib/silcutil/silcutil.[ch].
2960 Added silc_string_regex_match to match two strings. It returns
2961 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2963 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Imported GNU regex to the soruce tree into lib/contrib.
2966 Fixed some compiler warning from the regex.c.
2968 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Fixed MOTD command in the server to work in router environment.
2972 * Fixed the MOTD command in the client library to support
2973 the server argument in the command.
2975 * Added `nickname_len' argument to the silc_idlist_add_client
2976 in the server, as the `nickname' argument may be binary data
2979 * Added silc_idlist_get_channels to return all channels from
2982 * Implemented LIST command to the server. Affected file is
2985 * Implemented the LIST command to the client library and on the
2988 * Added [<user count>] argument to the LIST command reply.
2989 With private channels the user count is not shown.
2991 * Updated TODO and README.
2993 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * The client entry's data.registered must be TRUE even with
2996 global client entry on global client list. The data.registered
2997 is used to check whether the client is anymore in the network,
2998 for example with WHOWAS command so it must be valid.
3000 * Fixed the WHOWAS command in the server. It now actually works
3001 in router environment. Added function into silcd/command_reply.c
3002 silc_server_command_reply_whowas_save.
3004 * Added silc_idlist_purge function to the silcd/idlist.c
3005 to periodically purge the ID Cache.
3007 * Fixed INFO command in the server. It works now in router
3008 environment. Added <server name> argument to the INFO command
3009 reply. Updated the protocol specs.
3011 * Fixed minor bug in silc_idcache_purge to not purge if the
3012 expire value is zero.
3014 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3015 they were buggy because of the WHOWAS information.
3017 * Fixed local command MSG to handle the async resolving of
3018 the remote client properly. It used to fail the first MSG.
3019 Affected file silc/local_command.c.
3021 * Added `data_len' field to SilcIDCache context.
3023 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Update TODO. Todo in commands in the server.
3027 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3030 used by routers as broadcast packet to inform other routers
3031 about the changed user mode.
3033 Implemented the notify handling in the server. Affected file is
3034 silcd/packet_receive.c. Added the function
3035 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3037 * Added new generic Channel Payload and deprecated the New Channel
3038 Payload. The New Channel Payload is now the generic Channel
3041 * Added new argument `mode' to the silc_server_send_new_channel
3042 as it is required in the Channel Payload now.
3044 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3045 and created a new and real SilChannelPayload to represent the
3046 new generic Channel Payload. Implemented the encode/decode
3047 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3049 * Added silc_server_get_client_channel_list to return the list
3050 of channels the client has joined for WHOIS command reply.
3051 Affected file silcd/server.[ch].
3053 * Implemented the channel list sending in the WHOIS command reply
3054 in server and in the client.
3056 Implemented the channel list displaying on the user interface
3057 as well. Affected file silc/client_ops.c.
3059 * Added silc_channel_payload_parse_list to parse list of Channel
3060 Payloads. It returns SilcDList list of SilcChannelPayloads.
3061 Client for example can use this function to parse the list of
3062 channels it receives in the WHOIS command reply. The caller
3063 must free the list by calling silc_channel_payload_list_free.
3064 Affected files lib/silccore/silcchannel.[ch].
3066 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Added one new argument <user mode> to the WHOIS command reply
3069 to return the mode of the user in SILC. Updated the protocol
3072 Implemented it to the server and client.
3074 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Fixed the mode printing on the user interface on joining.
3077 Affected file silc/client_ops.c.
3079 * Implemented the UMODE command and user modes in general to the
3080 client library and to the user interface.
3082 * Implemented the UMODE command to the server.
3084 * The server now sends UNKNOWN_COMMAND error status if client sends
3085 unknown command. Affected file silcd/command.c.
3087 * All server commands now handle the command identifier the right
3088 way when sending the command reply to the client. The client can
3089 use to identify the command replies with the identifier.
3091 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Added silc_server_get_client_route to resolve the route to
3094 the client indicated by the client ID. Affected file is
3097 * Added silc_server_relay_packet as general function to relay
3098 packet to arbitrary destination. This deprecates functions
3099 like _send_private_message_key, _relay_notify etc. Affected
3100 file is silcd/packet_send.[ch].
3102 Removed silc_server_send_key_agreement,
3103 silc_server_send_private_message_key and
3104 silc_server_packet_relay_notify functions from the file
3105 silcd/packet_send.[ch].
3109 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3110 server. Affected file silcd/packet_receive.[ch].
3112 * Implemented the KILL command to the client. Implemented the
3113 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3114 Affected files lib/silcclient/command[_reply].c and
3115 lib/silcclient/client_notify.c. Implemented the KILL notify
3116 printing in the user inteface.
3118 * Fixed a lot silc_parse_nick memory leaks from the client
3119 library in the file lib/silcclient/command.c.
3121 * Changed the silc_server_send_notify_on_channels's `sender'
3122 argument from SilcSocketConnection to SilcClientEntry to
3123 check the sender as entry and not as connection object and not
3124 to send to the client provided as argument. The affected file
3125 is silcd/packet_send.[ch].
3127 * The notify packets that are destined directly to the client used
3128 to not to be processed by the server. Now changed that and the
3129 server processes all notify packets. After relaying the packet
3130 to the client the notify packet is processed in the server.
3132 * The silc_server_free_client_data now checks whether there is
3133 pending outgoing traffic for the client and purges the data to
3134 the network before removing the client entry.
3136 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3139 an client is killed from the SILC Network. Updated the protocol
3142 Added new function silc_server_send_notify_killed to the
3143 silcd/packet_send.[ch].
3145 * Added function silc_server_packet_relay_notify to relay notify
3146 packets that are destined directly to a client. In this case
3147 the server does not process the notify packets but merely relays
3148 it to the client. Affected file silcd/packet_send.[ch].
3150 Added also silc_server_packet_process_relay_notify to check
3151 whereto relay the notify. Affected file is
3152 silcd/packet_receive.[ch].
3154 * Implemented the KILL command to the server.
3158 * Added the backup schema desgined last fall to the protocol
3159 specs for everyone to see. The specification is in the
3160 *-spec-xx.txt draft and the packet type definitions for the
3161 backup routers is in *-pp-xx.txt draft. Thusly, added also
3162 new packet type SILC_PACKET_CELL_ROUTERS.
3164 * A big security problem in the implementation discovered. The
3165 signoff of an client did not cause new channel key generation
3166 which it of course should've done. The channel keys must be
3167 always re-generated when client leaves (or signoffs) the channel.
3168 The silc_server_remove_from_channels funtion now handles
3169 the channel key re-generation.
3171 * Added `sender' argument to the silc_server_send_notify_on_channels
3172 to not to send the client provided as argument. Affected file
3173 silcd/packet_send.[ch].
3175 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Implemented OPER and SILCOPER commands into the server and
3180 * Added silc_auth_verify and silc_auth_verify_data to verify
3181 the authentication directly from the authentication payload.
3182 It supports verifying both passphrase and public key based
3183 authentication. Affected file lib/silccore/silcauth.[ch].
3185 * Added `hash' field to the SilcIDListData structure. It is the
3186 hash negotiated in the SKE protocol. Affected file is
3189 * Slight redesigning of the SilcAuthPayload handling routines.
3190 Do not send SilcPKCS but SilcPublicKey as argument.
3192 * Implemented the public key authentication support to the
3193 serverconfig. The public key is loaded from the provided path
3194 and saved as authentication data to void * pointer. Thus,
3195 changed the unsigned char *auth_data to void *auth_data;
3197 * Fixed SHUTDOWN command to send the reply before the server
3198 is shutdown. :) Affected file silcd/command.c.
3200 * Fixed fatal bug in CONNECT command. The hostname was invalid
3201 memory and server crashed. Affected file silcd/command.c.
3203 * Fixed fatal bug in CLOSE command. The server_entry became
3204 invalid but was referenced later in the command. Affected file
3207 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Fixed fatal bug in failure packet handling. Server ignored
3210 the failure and thus crashed when it came.
3214 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3217 that the command may be executed only once in (about) 2 seconds.
3218 The old SILC_CF_LAG flag is same but allows command bursts up
3219 to five before limiting.
3221 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3222 server code. Various commands now includes the CF_LAG_STRICT
3223 flag to disallow any kind of miss-use of the command.
3225 * Fixed the silc_buffer_unformat to not to allocate any data
3226 if the length of the data is zero. It used to allocate the
3227 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3229 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Changed the format of AdminConnection configuration section
3232 in the server. Added username of the admin to the format.
3233 Affected files silcd/serverconfig.[ch].
3235 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3236 to return admin configuration data by host, username and/or
3239 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Implemented WHOWAS command to the server. Added the functions:
3243 silc_server_command_whowas_parse,
3244 silc_server_command_whowas_send_reply,
3245 silc_server_command_whowas_from_client and
3246 silc_server_command_whowas_from_server
3248 * Added <Client ID> argument to the WHOWAS command reply. Updated
3249 the protocol specs accordingly.
3251 * Implemented WHOWAS command and command_reply to the client
3254 Implemented the WHOWAS printing on the user interface.
3256 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added new argument to the WHOWAS command reply, the real name.
3259 It is an optional argument. Updated the protocol specs.
3261 * Added SilcIDCacheDestructor callback that is registered when
3262 the SilcIDCache is allocated. The callback is called when
3263 an cache entry in the ID Cache expires, or is purged from the
3264 cache. Added into lib/silccore/idcache.[ch].
3266 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3267 to destruct the client entries when the cache entry expires.
3268 Other ID Cache's in server and in the client library ignores
3271 * If the ID Cache entry's `expire' field is zero then the entry
3272 never expires. Added boolean `expire' argument to the
3273 silc_idcache_add function in the lib/silccore/idcache.[ch].
3274 If it is TRUE the default expiry value is used.
3276 * Added silc_server_free_client_data_timeout that is registered
3277 when client disconnects. By default for 5 minutes we preserve
3278 the client entry for history - for WHOWAS command.
3280 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Added support to the server to enforce that commands are not
3283 executed more than once in 2 seconds. If server receives
3284 commands from client more frequently, timeout is registered
3285 to process the commands. Affected file silcd/command.c.
3286 Added new function silc_server_command_process_timeout.
3288 * Changed NICK_NOTIFY handling in client library to check that
3289 if the client's nickname was changed, so there is no need to
3290 resolve anything from the server.
3292 * Removed error printing from the WHOIS and IDENTIFY commands.
3293 If error occurs then it is ignored silently in the client library.
3294 The application, however, may map the received error to
3295 human readable error string. The application currently maps
3296 the NO_SUCH_NICKNAME error to string.
3298 * Made the command status message public to the application. Moved
3299 them from lib/silcclient/command_reply.c to
3300 lib/silcclient/command_reply.h. The application can map the
3301 received command status to the string with the
3302 silc_client_command_status_message function.
3304 * Added check to the server to check that client's ID is same
3305 as the Source ID in the packet the client sent. They must
3308 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Added dist-bzip hook to the Makefile.am to make bzip2
3311 compressed distributions.
3313 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Server now enforces the maximum length for the nickname and
3316 the channel as protocol specification dictates. 128 bytes for
3317 nickname and 256 bytes for channel name.
3319 * Moved the WHOIS printing to the application. The client libary
3320 does not print out the WHOIS information anymore, the application
3321 must do it. Renamed silc_client_command_reply_whois_print to
3322 the silc_client_command_reply_whois_save.
3324 The client's idle time is also sent to the application now, and
3325 the idle is shown on screen.
3327 * Added silc_client_command_reply_identify_save to save the
3328 received IDENTIFY entries.
3330 * Do not check for channel private keys in message sending and
3331 reception if the channel does not have the PRIVKEY mode set.
3332 Affected file lib/silclient/client_channel.c.
3334 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3337 just surfaced after chaning the JOIN procedure.
3339 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Added silc_client_get_clients_by_list to get client entries
3342 from Client ID list, that is returned for example by JOIN
3343 and USERS command replies. The application should use this
3344 function for example when JOIN command reply is received to
3345 resolve the clients already on the channel (library does not
3346 do that anymore as USERS command reply is not used in the JOIN
3347 procedure anymore). Affected files lib/silcclient/silcapi.h and
3348 lib/silcclient/idlist.c.
3350 * JOIN command reply and USERS command reply returns now SilcBuffer
3351 pointers instead of unsigned char pointers when returning
3352 the client list and mode list.
3354 * Added <Client ID> argument to the JOIN command reply, mainly
3355 for the server to identify for which client the command was
3356 originally sent. Updated protocol specs accordingly.
3358 * Added SilcDlist private_key pointer to the SilcChannelEntry
3359 in the client to support the channel private keys. Affected
3360 file is lib/silcclient/idlist.h.
3362 * Added SilcChannelPrivateKey argument to the function
3363 silc_client_send_channel_message so that application can choose
3364 to use specific private ke if it wants to. If it is not provided,
3365 the normal channel key is used, unless private keys are set.
3366 In this case the first (key that was added first) is used
3367 as the encryption key.
3369 * Implemented the support for channel private key handling.
3370 Implemented the following functions:
3372 silc_client_add_channel_private_key,
3373 silc_client_del_channel_private_keys,
3374 silc_client_del_channel_private_key,
3375 silc_client_list_channel_private_keys and
3376 silc_client_free_channel_private_keys
3378 Affected file lib/silcclient/client_channel.c.
3380 * Added the support for the private keys in the channel message
3381 sending and encryption and in the message reception and
3382 decryption. Affected funtions are
3383 silc_client_send_channel_message and silc_client_channel_message.
3385 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Added SKE's key verify callback to the client library's
3388 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3390 * Removed the statement that server (or router) must send USERS
3391 command reply when joining to the channel so that the client
3392 knows who are on the channel. Instead, the client list and
3393 client's mode list is now sent in the JOIN command reply to the
3394 client who joined channel. This is better solution.
3396 * Added function silc_server_get_users_on_channel and function
3397 silc_server_save_users_on_channel to the silcd/server.[ch].
3399 * Removed function silc_server_command_send_users from the
3402 * Do not show topic on the client library anymore. The topic is
3403 sent in the command reply notify to the application and the
3404 application must show the topic now.
3406 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Added client searching by nickname hash into the IDENTIFY and
3409 WHOIS commands in the server as they were clearly missing from
3410 them. Affected file is silcd/command.c.
3412 * Fixed a bug in private message receiving in the client library.
3413 The remote ID was freed and it wasn't supposed, now it is
3416 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Minor fix to the channel payload; allocate the data area, as it
3419 needs to be of specific length.
3421 * If the key agreement port is zero then the operating
3422 system will define the bound port. Affected files are
3423 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3425 * Added new function silc_channel_payload_decrypt into the file
3426 lib/silccore/silcchannel.[ch].
3428 * Moved the channel message etc, check from silc_packet_decrypt
3429 to applications. The library calls now a generic
3430 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3431 when the packet is either normal or special. This was done to
3432 allow more wide range of checking that was not allowed when
3433 the code was in library. Now applications can do virtually any
3434 checks to the packet and return to the library the decision how
3435 the packet should be processed. Affected files are
3436 lib/silccore/silcpacket.[ch].
3438 Added silc_server_packet_decrypt_check to the server and
3439 silc_client_packet_decrypt_check to the client library.
3441 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3442 to send with specified source and destination information.
3444 * Channel message delivery between routers was broken after the
3445 channel key distribution was fixed earlier. The channel key
3446 was used be to distributed to other routers as well which is not
3447 allowed by the protocol. Now this is fixed and channel keys
3448 really are cell specific and the channel message delivery between
3449 routers comply with the protocol specification.
3451 * Fixed various commands in server to check also the global list
3452 for the channel entry and not just the local list. The affected
3453 file silcd/command.c.
3455 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added assert()s to buffer formatting and unformatting routines
3458 to assert (if --enable-debug) when error occurs. Affected
3459 file: lib/silcutil/silcbuffmt.c.
3461 * Changed to auto-reconnect to check whether the remote host is
3462 router and register the re-connect timeout if it is. It used
3463 to check that whether we are normal server, but router must do
3464 auto-reconnect with another router as well. Affected file
3467 * Removed the [<key len>] option from CMODE command as the cipher
3468 name decides the key length, nowadays. See the defined ciphers
3469 from the protocol specification.
3471 * Added [<hmac>] option to the CMODE command to define the HMAC
3472 for the channel. Added SILC_CMODE_HMAC channel mode.
3474 * Added [<hmac>] option for the JOIN command so that user can
3475 select which HMAC is used to compute the MACs of the channel
3478 * Added Hmac field to the Channel Message Payload. The integrity
3479 of plaintext channel messages are now protected by computing
3480 MAC of the message and attaching the MAC to the payload. The
3481 MAC is encrypted. Now, it is clear that this causes some
3482 overhead to the size of the packet but rationale for this is that
3483 now the receiver can verify whether the channel message decrypted
3484 correctly and also when private keys are set for the channel the
3485 receiver can decrypt the packet with several keys and check from
3486 the MAC which key decrypted the message correctly.
3488 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3489 lib/silccrypt/silccipher.[ch].
3491 * Added silc_hash_len to return the digest length into the
3492 lib/silcrypt/silchash.[ch].
3494 * Rewrote parts of Silc Channel Payload interface in the
3495 lib/silccore/silcchannel.[ch]. The encode function now also
3496 encrypts the packet and parse function decrypts it.
3498 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Fixed a minor formatting bug in the SKE's key material processing.
3501 It actually might have processed the keys wrong way resulting
3504 * Redefined the mandatory HMAC algorithms and added new algorithms.
3505 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3506 and hmac-md5 truncated to 96 bits. The mandatory is now
3507 hmac-sha1-96. Rest are optional (including the one that used
3508 to be mandatory). Rationale for this is that the truncated HMAC
3509 length is sufficient from security point of view and can actually
3510 make the attack against the HMAC harder. Also, the truncated
3511 HMAC causes less overhead to the packets. See the RFC2104 for
3514 * Added new [hmac] configuration section. The SKE used to use
3515 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3516 is of course wrong. The official names that must be proposed in
3517 the SKE are the ones defined in the protocol specification
3518 (hmac-sha1-96 for example). The user can configure any hmac
3519 using any hash function configured in the [hash] section. At
3520 least, the mandatory must be configured.
3522 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3524 * Added HMAC list to the SKE proposal list. It has now both
3525 hash algorithm list and HMAC list. This makes the protocol
3526 incompatible with previous versions. The SKE now seems to work
3527 the way it is supposed to work, for the first time actually.
3529 * Defined plain Hash algorithms to the protocol specification.
3532 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Implemented support for key agreement packets into the server.
3535 Added functions silc_server_key_agreement and
3536 silc_server_send_key_agreement. Other than these functions,
3537 server has nothing to do with this packet.
3539 * Added support for private message key packets into the server.
3540 Added functions silc_server_private_message_key and
3541 silc_server_send_private_message_key.
3545 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3546 called in the protocol's final callback instead in the END
3547 protocol state. This makes a little more sense and in the same
3548 time in client we can use the same protocol routines for normal
3549 key exchange and to key agreement packet handling as well.
3551 * Added to both client's and server's KE protocol context the
3552 SilcSKEKeyMaterial pointer to save the key material. We will
3553 bring the key material to the protocol's final callback by doing
3554 this. The final callback must free the key material.
3556 * Added SKE's packet_send callback into client's KE protocol
3557 context so that the caller can choose what packet sending function
3558 is used. This way we can use different packet sending when
3559 doing normal SKE when doing key agreement packet handling (in
3560 the key agreement packet handling we do not want to encrypt
3563 * Implemented the responder side of the key agreement routines
3564 in the client. The client can now bind to specified port and
3565 accept incoming key negotiation. The key material is passed
3566 to the application after the protocol is over.
3568 * Implemented the processing of incoming Key Agreement packet
3569 in the client. Added function silc_client_key_agreement to
3572 * Implemented the intiator side of the key agreement routines
3573 in the client. The client can now initiate key agreement with
3574 another remote client. The key material is passed to the
3575 application after the protocol is over.
3577 * Created client_keyagr.c to include all the key agreement
3580 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3581 SILC_TASK_CALLBACK except that it is not static.
3583 * Created client_notify.c and moved the Notify packet handling
3584 from the client.[ch] into that file.
3586 * Created client_prvmsg.c and moved all private message and
3587 private message key routines from the client.[ch] into that file.
3589 * Create client_channel.c and moved all channel message and
3590 channel private key routines from the client.[ch] into that file.
3592 * Changed silc_client_get_client_by_id_resolve to resolve with
3593 WHOIS command instead of IDENTIFY command, in the file
3594 lib/silclient/idlist.c.
3596 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3598 * Implemented the SKE's responder side to the Client library.
3600 * When FAILURE is received to the protocol do not trust it
3601 blindly. Register a timeout to wait whether the remote closes
3602 the connection as it should do it, only after that process the
3603 actual failure. This was changed to both client and server.
3605 * Added client_internal.h to include some of the structures
3606 there instead of client.h in lib/silcclient/.
3608 * Added function silc_task_unregister_by_callback to unregister
3609 timeouts by the callback function.
3611 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Some "Incomplete WHOIS info" errors has been appearing on the
3614 log files. Took away the entry->userinfo check from WHOIS
3615 reply sending. The entry->userinfo is now " " if client did not
3616 provide one. I thought this was fixed earlier but something
3617 is wrong still. Let's see if the error still appears.
3619 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Fixed a minor bug in the login when the channel key is
3622 re-generated in the server. It used to generate the key in
3623 wrong order and thus caused problems in the channel traffic.
3625 * Fixed a minor bug in channel key distsribution after
3626 KICK command. The key was not sent to the router even though
3629 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Added silc_ske_process_key_material_data as generic routine
3632 to process any key material as the SILC protocol dictates. The
3633 function is used by the actual SKE library but can be used by
3634 applications as well. This relates to the private message keys
3635 and the channel private keys since they must be processed the
3636 same way the normal SILC session keys. The protocol dictates
3637 this. Affected files: lib/silcske/silcske.[ch].
3639 Added also silc_ske_free_key_material to free the
3640 SilcSKEKeyMaterial structure.
3642 * Defined silc_cipher_set_key function to set the key for
3643 cipher without using the object's method function. The affected
3644 files: lib/silccrypt/silccipher.[ch].
3646 * Implemented silc silc_client_add_private_message_key,
3647 silc_client_add_private_message_key_ske,
3648 silc_client_del_private_message_key,
3649 silc_client_list_private_message_keys and
3650 silc_client_free_private_message_keys functions in the
3653 Added functions silc_client_send_private_message_key to send
3654 the Private Message Key payload and silc_client_private_message_key
3655 to handle incoming Private Message Key payload.
3657 * Added Cipher field to the Private Message Key payload to set
3658 the cipher to be used. If ignored, the default cipher defined
3659 in the SILC protocol (aes-256-cbc) is used.
3661 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Removed lib/silcclient/ops.h file.
3665 Redefined parts of the SILC Client Library API. Created new
3666 file silcapi.h that deprecates the ops.h file and defines the
3667 published Client Library API. Defined also private message key
3668 API and channel private key API into the file.
3670 This is the file that the application must include from the
3671 SILC Client Library. Other files need not be included by
3672 the application anymore.
3674 * Added new key_agreement client operation callback and also
3675 defined the Key Agreement library API for the application.
3677 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3680 is used by clients to request key negotiation between another
3681 client in the SILC network. If the negotiation is started it
3682 is performed using the SKE protocol. The result of the
3683 negotiation, the secret key material, can be used for example
3684 as private message key.
3686 Implemented the Key Agreement payload into the files
3687 lib/silccore/silauth.[ch].
3689 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Redefined ciphers for the SILC protocol. Added some new ciphers
3692 and defined the key lengths for the algorithms. Changed the
3693 code accordingly. The default key length is now 256 bits.
3695 * Fixed SKE key distribution function silc_ske_process_key_material
3696 when the key length is more than 128 bits. The default key
3697 length in SILC is now 256 bits.
3699 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3700 to indicate unsupported algorithm.
3702 * Renamed rijndael.c to aes.c and all functions as well.
3704 * Fixed a long standing channel key setting bug in client library.
3705 Weird that it has never surfaced before.
3707 * Fixed bug in channel deletion. If the entire channel is removed
3708 then it must also delete the references of the channel entry
3709 from the client's channel list as the client's channel entry and
3710 the channel's client entry share same memory.
3712 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Implemented CONNECT and SHUTDOWN commands in the client.
3716 * Implemented CLOSE command to the client.
3718 * Added the function silc_idlist_find_server_by_name into the
3719 files silcd/idlist.[ch].
3721 Added the function silc_idlist_find_server_by_conn into the
3722 files silcd/idlist.[ch].
3724 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * DIE command was renamed to SHUTDOWN. Updated the both code
3729 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3730 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3732 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3735 * Added function silc_server_create_connection function to create
3736 connection to remote router. My server implementation actually
3737 does not allow router to connect to normal server (it expects
3738 that normal server always initiates the connection to the router)
3739 so the CONNECT command is only good for connecting to another
3742 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3745 or some other client was kicked from the channel.
3747 Implemented the handling of the notify type to both client
3750 Implemented silc_server_send_notify_kicked to send the KICKED
3751 notify. It is used to send it to the server's primary router.
3753 * Implemented the KICK command into server and client.
3755 * Added `query' argument to the silc_idlist_get_client function
3756 to indicate whether to query the client from server or not if
3759 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3760 to indicate that the client is not channel founder.
3764 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Removed the rng context from SilcPacketContext structure and
3767 changed that the packet routine uses the Global RNG API.
3769 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Added support for quit message that client can "leave" on the
3772 channel when it quits the SILC. It is ditributed inside the
3773 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3775 Added silc_server_free_client_data that will take the
3776 signoff message as argument.
3778 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3780 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Updated parts of the protocol specification to keep it up
3785 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3788 payloads in one packet.
3790 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3791 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3792 use now the new List flag.
3794 * Also deprecated the following packet types: REPLACE_ID,
3795 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3797 * Added list support for Notify packet in server.
3799 * Added silc_server_send_notify_channel_change to send the
3800 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3801 the silc_server_send_replace_id.
3803 * Added silc_server_send_notify_nick_change to send the
3804 NICK_CHANGE notify type. Deprecates the function
3805 silc_server_send_replace_id.
3807 * Added silc_server_send_notify_join to send the JOIN notify type.
3808 Deprecates the function silc_server_send_new_channel_user.
3810 * Added silc_server_send_notify_leave to send LEAVE notify type.
3811 Deprecates the function silc_server_send_remove_channel_user.
3813 * Added silc_server_send_notify_cmode and
3814 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3815 types. Deprecates the silc_server_send_set_mode function.
3817 * Added SERVER_SIGNOFF notify type to indicate that server has
3818 quit. This means that all clients on the channel from that
3819 server will drop. This can be also used when netsplit happens.
3821 Deprecated REMOVE_ID packet type since it is not needed anymore
3824 Added silc_server_send_notify_server_signoff to send the
3825 SERVER_SIGNOFF notify type. Deprecates the function
3826 silc_server_send_remove_id.
3828 Added also silc_server_send_notify_signoff to send the
3829 SIGNOFF notify type.
3831 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3832 SILC protocol from this day on. Changed the protocol
3833 specification as well.
3835 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3836 notify type. It is used between routers to notify about
3837 topic changes on a channel.
3839 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3842 * Partly updated the protocol specification to comply with the
3843 changes now made. It is still though a bit outdated.
3845 * The JOIN notify type now takes one extra argument <Channel ID>.
3846 The packet used to be destined to the channel but now the
3847 JOIN type may be sent as list thus it is impossible to
3848 destine it to any specific channel. By adding this argument
3849 it is again possible.
3851 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * Added CREDITS file. The CHANGES and CREDITS file will appear
3854 in the distribution as well.
3856 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3859 types in the server's silcd/packet_receive.c.
3861 * Implemented CMODE and CUMODE to work in router environment.
3863 * Fixed minor encoding and decoding buglet from the
3864 lib/silccore/silcmode.c.
3866 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3869 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3871 * Changed all SilcConfigServer* and silc_config_server* to
3872 SilcServerConfig* and silc_server_config*, respectively.
3875 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Associated the ID (client or server ID) to the Authentication
3878 Payload to avoid any possibility of forging. Updated the
3879 protocol specification and the code accordingly.
3881 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * The RSA key length is now save to the RsaKey context in the
3884 key generation process in lib/silccrypt/rsa.c. The key length
3885 is now used to figure out the maximum size of the block allowed
3886 to be encrypted/signed.
3888 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3889 is equivalent to the silc_mp_mp2bin but does not allocate any
3892 * Changed silc_mp_mp2bin API to take length argument. If it is
3893 non-zero then the buffer is allocated that large. If zero, then
3894 the size is approximated using silc_mp_sizeinbase, which however
3897 * Created Global RNG API which is global RNG that application can
3898 initialize. After initializing, any routine anywhere in the
3899 code (including library) can use RNG without allocating a new
3900 RNG object. This was done to allow this sort of use of the
3901 RNG in code that has no chance to allocate RNG object. All
3902 applications currently allocate this and many routines in the
3903 library use this. Affected file lib/silccrypt/silcrng.[ch].
3905 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3906 it to use the Global RNG API.
3908 * Defined Authentication Payload into protocol specification that
3909 is used during SILC session to authenticate entities. It is
3910 used for example by client to authenticate itself to the server
3911 to obtain server operator privileges.
3913 Implemented this payload into the lib/silccore/silcauth.[ch].
3914 Implemented also routines for public key based authentication
3915 as the new protocol specification dictates.
3917 Moved definitions of different authentication methods from
3918 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3920 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3921 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3922 silc_pkcs_verify_with_hash functions into the file
3923 lib/silccrypt/silcpkcs.[ch].
3925 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * The client entry's userinfo pointer must be always valid.
3928 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3929 will fail since it requires the userinfo. Now, the userinfo
3930 is allocated as "" if actual userinfo does not exist. Actually,
3931 it must exist and it is totally Ok to drop client connections
3932 that does not announce the userinfo. However, we will make
3933 this workaround for now.
3935 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3936 to return the remote port by socket.
3938 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3941 SILC_SERVER_PENDING_EXEC and added an new macro
3942 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3943 data or when error occurs while processing the pending command.
3945 Added new argument `destructor' into silc_server_command_pending
3946 and to the SilcServerCommandPending object. This destructor is
3947 now called after calling the pending callback or if error occurs
3948 immediately. If error occurs the actual pending callback won't
3949 be called at all - only the destructor. The destructor may be
3950 NULL if destructor is not needed.
3952 All this applies for client library code as well. Similar
3953 changes were made there as well for the pending commands.
3955 In the client, the application must now allocate the
3956 SilcClientCommandContext with the silc_client_command_alloc
3959 * Added reference counter to the SilcServerCommandContext. Added
3960 function silc_server_command_alloc and silc_server_command_dup
3963 Same type of functions added to the client library for the same
3966 * Removed the cmd_ident from IDListData away since it is now
3967 global for all connections. It is the command identifier used
3968 in command sending and with pending commands. The affected file
3971 * Added reference counter to the SilcSocketConnection objecet to
3972 indicate the usage count of the object. The object won't be
3973 freed untill the reference counter hits zero. Currently only
3974 server uses this, and client ignores it. The client must be
3975 set to use this too later. The affected files are
3976 lib/silccore/silcsockconn.[ch]. Added also the function
3977 silc_socket_dup to increase the reference counter.
3979 This was mainly added because it is possible that the socket
3980 is removed underneath of pending command or other async
3981 operation. Now it won't be free'd and proper DISCONNECTING
3982 flags, etc. can be set to avoid sending data to connection that
3983 is not valid anymore.
3985 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3986 the connection. After that it sets SILC_SET_DISCONNECTED.
3987 It is, however, possible that the socket data is not still freed.
3988 The silc_server_packet_process now checks that data is not
3989 read or written to connection that is DISCONNECTED. The socket
3990 get's freed when the reference counter hits zero.
3992 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Changed the client operation API: channel_message operation's
3995 `sender' is now the client entry of the sender, not the nickname
3996 and the `channel' is the channel entry, not the channel name.
3998 In the private_message operation the `sender' is now also the
3999 client entry of the sender not the nickname.
4001 Affected file is lib/silcclient/ops.h and all applications
4002 using the client operations.
4004 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4006 * Moved the calling of ops->connect() from connect_to_server_final
4007 into receive_new_id functin since that is the point when the
4008 client is actually allowed to send traffic to network. The
4009 affected file is lib/silcclient/client.c.
4011 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4014 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4015 (if needs broadcasting) instead of broadcasting the packets one
4016 by one which would make a burst in the network traffic.
4018 * Added `broadcast' argument to the functions in silcd/server.[ch]
4019 silc_server_create_new_channel[_with_id] to indicate whether
4020 to send New Channel packet to primary router.
4022 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added new function into the silcd/server.[ch] files:
4025 silc_server_create_new_channel_with_id to create new channel with
4026 already existing Channel ID.
4028 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4029 lib/silccore/silcpacket.h. This packet is used t send list of
4030 Set Mode payloads inside one packet. Server uses this to set
4031 the modes for the channels and clients on those channels, that it
4032 announced to the router when it connected to it. The protocol
4033 specification has been updated accordingly.
4035 * The silc_server_new_channel did not handle the packet coming
4036 from normal server as it normally does not send that. However,
4037 when it announces its channels it does send it. Implemented
4038 the support for that.
4040 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4041 into the file lib/silccore/id.h.
4043 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Fixed memory leaks in the functions silc_idlist_del_client,
4046 silc_idlist_del_channel and silc_idlist_del_server in the file
4047 silcd/idlist.c. All of those leaked like a sieve.
4049 * Fixed some small memory leaks in the client's function
4050 silc_client_notify_by_server.
4052 * Added functions into silcd/server.c: silc_server_announce_clients,
4053 silc_server_announce_channels and silc_server_announce_server.
4054 These functions are used by normal and router server to announce
4055 to its primary router about clients, channels and servers (when
4056 router) that we own. This is done after we've connected to the
4059 These functions effectively implements the following packet types:
4060 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4061 and SILC_PACKET_NEW_ID_LIST.
4063 * Added new functions into the silcd/packet_receive.[ch]:
4064 silc_server_new_id_list, silc_server_new_channel_list and
4065 silc_server_new_channel_user_list to handle the incoming
4066 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4068 * Added support of changing Channel ID in the function
4069 silc_server_replace_id. If the server that announces a channel
4070 to the router already exists in the router (with same name but
4071 with different Channel ID), router is responsible to send
4072 Replace ID packet to the server and force the server to change
4073 the Channel ID to the one router has.
4075 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4076 client that the Channel ID has been changed by the router. The
4077 normal server sends this to the client. Client must start using
4078 the new Channel ID as the channel's ID.
4080 Implemented handling of this new type into lib/silcclient/client.c
4081 into the function silc_client_notify_by_server.
4083 * Added new function silc_idlist_replace_channel_id into the files
4084 silcd/idlist.[ch] to replace the Channel ID.
4086 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Call silc_server_command_identify_check always when processing
4089 the IDENTIFY command in silcd/command.c
4091 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4094 send keepalive packets. The packet can be sent by clients,
4095 servers and routers.
4097 Added function silc_socket_set_heartbeat into the file
4098 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4099 If not set, the heartbeat is not performed. The actual
4100 heartbeat is implemented in the low level socket connection
4101 library. However, application is responsible of actually
4104 Added silc_server_send_heartbeat to send the actual heartbeat
4105 packet into silcd/packet_send.[ch]. Server now performs
4106 keepalive with all connections.
4108 * Added silc_task_get_first function into lib/silcutil/silctask.c
4109 to return the timeout task with shortest timeout. There was a bug
4110 in task unregistration that caused problems. TODO has been
4111 updated to include that task system must be rewritten.
4113 * The client library will now resolve the client information when
4114 receiving JOIN notify from server for client that we know but
4115 have incomplete information.
4117 * Rewrote parts of silc_server_remove_from_channels and
4118 silc_server_remove_from_one_channel as they did not remove the
4119 channel in some circumstances even though they should've.
4121 * Encryption problem encountered in server:
4123 The LEAVE command used to send the Channel Key packet to the
4124 router immediately after generating it. However, the code
4125 had earlier sent Remove Channel user packet but not immediately,
4126 ie. it was put to queue. The order of packets in the router
4127 was that Channel Key packet was first and Remove Channel User
4128 packet was second, even though they were encrypted in the
4129 reverse order. For this reason, MAC check failed. Now, this
4130 is fixed by not sending the Channel Key packet immediately but
4131 putting it to queue. However, this is more fundamental problem:
4132 packets that are in queue should actually not be encrypted
4133 because packets that are sent immediately gets encrypted
4134 actually with wrong IV (and thus MAC check fails). So, packets
4135 that are in queue should be encrypted when they are sent to
4136 the wire and not when they put to the queue.
4138 However, the problem is that the current system has not been
4139 designed to work that way. Instead, the packet is encrypted
4140 as soon as possible and left to the queue. The queue is then
4141 just purged into wire. There won't be any fixes for this
4142 any time soon. So, the current semantic for packet sending
4145 o If you send packet to remote host and do not force the send
4146 (the packet will be in queue) then all subsequent packets to the
4147 same remote host must also be put to the queue. Only after the
4148 queue has been purged is it safe again to force the packet
4151 o If you send all packets immediately then it safe to send
4152 any of subsequent packets through the queue, however, after
4153 the first packet is put to queue then any subsequent packets
4154 must also be put to the queue.
4156 Follow these rules and everything works fine.
4158 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Added new function silc_server_remove_clients_by_server to
4161 remove all client entries from ID list when the server connection
4162 is lost. In this case it is also important to invalidate all
4163 client entires as they hold the invalid server entry. This
4164 fixes fatal bug when server has lost connection and will reconnect
4167 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Made some sanity checks to silc_server_daemonise like to check
4170 whether the requested user and group actually exists.
4172 * Added sanity check to SKE's silc_ske_responder_finish to check
4173 that the public and private key actually is valid.
4175 * Invalidate the client's nickname when receiving Replace ID
4176 packet and the Client ID is being replaced. This means that the
4177 server will query the nickname if someone needs it (client)
4180 * Sort the ID Cache in client library when the ID Cache data
4181 has changed (needs sorting).
4183 * Do not allow for SILC client to create several connections to
4184 several servers. The client does not support windows right now
4185 and generating multiple connections causes weird behaviour.
4187 Irssi-silc client does support windows and can handle several
4188 connections without problems, see: www.irssi.org and SILC plugin.
4190 * Fixed some places where client was added to the IDList. The
4191 rule of thumb is following (in order to get everything right):
4192 If the client is directly connected local client then the
4193 `connection' argument must be set and `router' argument must be
4194 NULL to silc_idlist_add_client function. If the client is not
4195 directly connected client then the `router' argument must
4196 bet set and the `connection' argument must be NULL to the
4197 silc_idlist_add_client function.
4199 * The funtion silc_server_packet_send_local_channel actually did
4200 not check whether the client was locally connected or not. It
4201 does that now. Fixed a bug related to LEAVE command.
4203 * Fixed Remove Channel User payload parsing bug in server's
4204 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4206 * The server's silc_server_save_channel_key now checks also the
4207 global ID list for the channel as it might not be in the local
4208 list. Fixed a bug related to LEAVE command.
4210 * Is this the end of the [<unknown>] buglet that has been lurking
4211 around for a long time? A little for loop fix in server's
4212 silc_server_command_whois_parse that is used by both IDENTIFY
4213 and WHOIS command. At least, this was a clear bug and a cause
4214 of one type of [<unknown>] buglet.
4216 * WHOIS and IDENTIFY commands call the function
4217 silc_server_command_[whois/identify]_check function even if
4218 we are not router server.
4220 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Added --with-gmp configuration option. If set the GMP
4223 is always compiled in the SILC source tree. If not set then
4224 it is checked whether the system has the GMP3 installed. If
4225 it has then the GMP won't be compiled (the system's headers
4226 and library is used), if it doesn't have it then the GMP is
4227 compiled in the SILC source tree.
4229 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Changed RSA private exponent generation to what PKCS #1
4232 suggests. We try to find the smallest possible d by doing
4233 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4234 not security fix but optimization.
4236 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Added new config entry [Identity] to fork the server and run
4239 it as specific user and group. A patch from Bostik.
4241 * Imported Dotconf configuration library into lib/dotconf.
4242 This will be used to create the SILC configuration files later.
4243 It will appear in the distsribution after this commit.
4245 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * A big code auditing weekend happening. Auditing code for
4248 obvious mistakes, bugs and errors. Also, removing any code
4251 Removed files for being obsolete:
4253 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4254 inline in the file lib/silcutil/silcbuffer.h)
4256 o lib/silcutil/silcbufutil.c (the header has inline versions)
4258 Changed code to fix possible error conditions:
4260 o The buffer formatting routines now check that the destination
4261 buffer really has enough space to add the data. This applies for
4262 both buffer formatting and unformatting
4263 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4264 unformatting was changed to accomodate following rules:
4265 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4266 sent to the function while XXX_*STRING will not allocate or copy
4267 the data into the buffer. Instead it sets the pointer from the
4268 buffer into the pointer sent as argument (XXX_*STRING used to
4269 require that the pointer must be allocated already). This change
4270 makes this whole thing a bit more consistent and more optimized
4271 (note that the data returned in the unformatting with XXX_*STRING
4272 must not be freed now). The routines return now -1 on error.
4274 o Tried to find all code that use buffer_format and buffer_unformat
4275 and added return value checking to prevent formatting and
4276 especially unformatting errors and possible subsequent fatal
4279 o Changed ske->x and ske->KEY to mallocated pointers in
4280 lib/silcske/silcske.h. Fixed possible data and memory leak.
4282 o Added return value checking to all *_parse* functions. Fixed
4283 many memory leaks as well.
4285 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4286 so that buffer overflows would not happen. All code now also
4287 checks the return value as it can fail.
4289 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added reconnection support to server if the normal server looses
4292 its connection to the router (for example if router is rebooted).
4293 The server performs normal reconnection strategy implemented
4294 to the server. Affected file silcd/server.c.
4296 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Added new packet type SILC_PACKET_SET_MODE that is used to
4299 distribute the information about changed modes (for clients,
4300 channels and clients channel modes) to all routers in the
4301 network. Updated the protocol specification accordingly.
4303 Added functions into silcd/packet_send.c and
4304 silcd/packet_receive.c: silc_server_send_set_mode,
4305 silc_server_set_mode.
4307 Added new files silcmode.[ch] into lib/silccore that implements
4308 the encoding and decoding of Set Mode Payload. Added new type
4309 SilcSetModePayload. Moved the definitions of different modes
4310 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4312 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Oops, a little mistake in server's connection authentication
4315 protocol. The protocol is not ended with FAILURE but with
4316 SUCCESS if the authentication is Ok. :) Affected file is
4319 * Implemented NICK_CHANGE notify handling in server in the file
4320 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4321 the local clients on the channel. After the changing nickname
4322 in router environment snhould work and the [<unknown>] nickname
4323 should appear no more.
4325 The silc_server_replace_id function that receives the Replace ID
4326 payload now sends the NICK_CHANGE notify type also in the file
4327 silcd/packet_receive.c
4329 * Changed WHOIS and IDENTIFY command to support the maximum amount
4330 of arguments defined in protocol specs (3328 arguments). This
4331 fixed a bug that caused problems when there were more than three
4334 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Added extra parameter, command identifier, to the
4337 silc_client_send_command so that explicit command identifier
4340 Changed that ID list routines uses specific command identifier
4341 when sending WHOIS/IDENTIFY requests to the server so that they
4342 can be identified when the reply comes back.
4344 Affected files lib/silcclient/command.[ch],
4345 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4347 * Added `sender' argument to silc_server_packet_send_to_channel
4348 to indicaet the sender who originally sent the packet to us
4349 that we are now re-sending. Ignored if NULL. Affected file
4350 silcd/packet_send.[ch].
4352 * Added some server statistics support in silcd/server_internal.h
4353 SilcServerStatistics structure and around the server code. Also
4354 send some nice statistics information when client is connecting
4357 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Fixed channel ID decoding in server's JOIN command reply in
4360 silcd/command_reply.c
4362 * Fixed braodcasting of replace ID payload to not to send it if
4363 we are standalone server in silcd/packet_receive.c.
4365 * Fixed all channel message sending routines to not to send
4366 packets to clients that has router set, since they are routed
4367 separately in the same function earlier. Affects file
4368 silcd/packet_send.c and all channel packet sending functions.
4370 * In USERS reply, res_argv[i] are not allocated, the table
4371 is allocated. Thus changed that free the table, not its
4374 * In server's whois_check and identify_check if the client is
4375 locally connected do not send any WHOIS commands - they are not
4378 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Fixed some minor bugs in client when sending WHOIS command. The
4381 arguments was in wrong order.
4383 * Removed statis function add_to_channel from server in
4384 silcd/command.c that was previously used with the joining but
4387 * Tested USERS command in router environment successfully with two
4388 routers, two servers and two clients.
4390 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Reorganized the USERS command and command reply in client library
4393 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4394 When the command is given by user we register a pending command
4395 callback that will reprocess the command after the reply has been
4396 received from the server. When reprocessing the packet we then
4397 display the information. Thus, the USERS information is displayed
4398 now in the command callback instead of in the command reply
4399 callback. The processing of the command is same as previously
4400 when server has sent the command reply in the JOINing process.
4402 * Added to USERS command in silcd/command_reply.c to join the client,
4403 we didn't use to know about, to the channel after we've created
4404 a client entry for it. Also, for clienet we did know already still
4405 check whether it is on the channel or not and add it if not.
4407 * Removed silc_server_command_join_notify as the function and its
4410 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Changed the client's pending command handling to the same as the
4413 server's pending command handling. It is also now possible to
4414 execute command reply functions from other command reply
4415 function as the function callbacks for commands and command
4416 replies are one and same. The pending commands are not static
4417 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4418 in client connection context. Thus, pending commands are server
4419 connection specific as it is convenient.
4421 Changed the function silc_client_command_pending and
4422 silc_client_command_pending_del and added new function
4423 silc_client_command_pending_check. Removed the
4424 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4427 * Added cmd_ident, current command identifier, to the client
4428 connection context in lib/silcclient/client.h to keep track on
4429 command identifiers used in command sending. Client's command reply
4430 function handling now supports the mandatory command identifiers.
4432 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4433 funtions in client to fully support pending command callbacks.
4435 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4436 as one of the arguments to the application in the command reply
4439 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4440 before first releasing SILC but came back. Now it is removed again
4441 and should come back nomore. The FORWARDED flag was used only
4442 by the JOINing procedure by forwarding the command packet to router.
4443 Now, the JOINing procedure has been changed to more generic (due
4444 to various router environment issues) and FORWARDED is not needed
4445 anymore for anything. The protocol specification is yet to be
4448 Now, removed silc_server_packet_forward from server and the flag
4449 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4451 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Renamed NAMES command to USERS command. The NAMES was named that
4454 due to historical reasons. Now it is renamed. Also, rewrote
4455 parts of the USERS command. The nickname list is not sent anymore
4456 by the server. Only Client ID and mode lists are sent in the USERS
4457 command. Changed this also to the protocol specification.
4459 The client now resolves the names and stuff after it receives
4460 the USERS list from the server when joining to the channel.
4462 * WHOIS and IDENTIFY commands has been changed to support multiple
4463 Client ID's per command. One can now search for multiple users
4464 in the network by sending only one WHOIS or IDENTIFY command.
4465 Changed the code and the protocol specifications.
4467 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4468 uses silc_server_command_whois_parse to parse the request. */
4470 * If normal server, do not parse the WHOIS and IDENTIFY requests
4471 before sending it to the router. Saves some time.
4473 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Fixed JOIN command on client library. Wrong number of arguments
4476 used to crash the client.
4478 * Added silc_server_channel_has_global function to check whether
4479 channel has global users or not.
4481 * Added silc_server_channel_has_local function to check whether channel
4482 has locally connected clients on the channel.
4484 * The silc_server_remove_from_one_channel now checks whether the
4485 channel has global users or not after given client was removed from
4486 the channel. It also checks whether the channel has local clients
4487 on the channel anymore. If it does not have then the channel entry
4488 is removed as it is not needed anymore.
4490 * The silc_server_notify now checks on JOIN notify whether the joining
4491 client is one of locally connected or global. If it is global then
4492 the channel has now global users on the channel and that is marked
4493 to the channel entry. Also, it now saves the global client to
4494 global list who is joining and JOINs it to the channel. This is
4495 for normal server, that is.
4497 Changed silc_server_send_notify_on_channel,
4498 silc_server_packet_relay_to_channel and
4499 silc_server_packet_send_to_channel check if we are normal server
4500 and client has router set (ie. global client) do not send the
4501 message to that client, as it is already routed to our router.
4503 * Implemented LEAVE notify type handling in silc_server_notify
4506 * Tested LEAVE command in router environment successfully. Tested
4507 with two routers, two servers and two clients.
4511 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4513 * Implemented SIGNOFF notify type handling in silc_server_notify
4516 * silc_server_remove_id now removes the client entry from all channels
4517 it has joined and thusly sends SIGNOFF notify type.
4519 * Rewrote the NAMES list generation in server by removing two excess
4520 loops. The lists are created now inside one loop.
4522 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * silc_server_remove_channel_user checks now also global list
4525 for channel and client.
4527 * silc_server_new_channel_user checks now both local and global
4528 list for channel and client. Fixed a bug in client id decoding.
4529 Used to decode wrong buffer.
4531 * silc_server_channel_message checks now both local and global
4532 list for channel entry.
4534 * Tested channel joining (hence JOIN) in router environment
4535 successfully. Tested with two routers, two servers and two
4538 * Tested channel message sending in router environment successfully.
4540 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added silc_server_save_channel_key into server.[ch] to save the
4543 received channel key in Channel Key payload processing. It is
4544 also used in JOIN command reply handling.
4546 Equivalent function silc_client_save_channel_key added into
4547 client.[ch] into client library.
4549 * Changed JOIN command reply to send information whether the channel
4550 was created or not (is existing already) and the channel key
4551 payload. Changed protocol specs accordingly.
4553 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4554 the request was sent by ID and not by nickname. Crashed on
4557 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4560 now correctly save the received data.
4562 * silc_server_free_sock_user_data now notifies routers in the
4563 network about entities leaving the network.
4565 At the same time implemented functions silc_server_remove_id
4566 and silc_server_send_remove_id to receive and send REMOVE_ID
4567 packets. The packet is used to notify routers in the network
4568 about leaving entities. The ID removed will become invalid in
4571 * Added function silc_idlist_del_server into server. Removes and
4572 free's server entry from ID list.
4574 * silc_server_private_message function now checks, if we are router,
4575 that the destination ID really is valid ID, naturally.
4577 * In router when NEW_ID packet is received (for new client) the
4578 hash of the Client ID is saved in the ID Cache but the
4579 client->nickname is set to NULL, instead of putting the hash
4582 IDENTIFY command now also checks that client->nickname must be
4583 valid. If it is not if will request the data from the server who
4584 owns the client. Added new function
4585 silc_server_command_identify_check.
4587 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4588 to set the command to already allocated Command Payload.
4590 * Tested private message sending in router environment with two
4591 routers, two servers and two clients. Fixed minor bugs and now
4594 * Fixed segfault from client's NAMES command. Used to crash if
4597 * Forwarded packets must not be routed even if it is not destined
4598 to the receiver. Changed server code comply with this.
4600 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added `require_reverse_mapping' boolean value to ServerParams
4603 structure. If TRUE (not default) the server will require that
4604 the connecting host has fully qualified domain name.
4606 If the reverse mapping is not required and hostname could not be
4607 found the IP address is used as hostname.
4609 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Implemented version string checking to both client and server.
4612 The check is incomplete currently due to the abnormal version
4613 strings used in development version of SILC.
4615 * Changed all command functions in server to use the new
4618 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Changed char *data to unsigned char *data in ID Cache system to
4621 support binary data as ID Cache data. Changed code to support
4622 binary data in lib/silccore/idcache.c.
4624 * Renamed silc_server_packet_relay_command_reply to
4625 silc_server_command_reply as it is normal packet receiving
4626 function. Rewrote the function to accept command replys for
4627 servers and not only for clients.
4629 * Mark remote router always as registered server if we are connecting
4630 to it. Otherwise, commands sent by the router to us are ignored.
4632 * All ID List find routines now returns the ID Cache Entry pointer
4633 as well if requested.
4635 * WHOIS command works now in router environment, tested with two
4636 routers, two servers and two clients.
4638 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4639 in router environment (as it is almost equivalent to WHOIS) but
4640 hasn't been tested thoroughly. Added new functions:
4642 silc_server_command_identify_parse
4643 silc_server_command_identify_send_reply
4644 silc_server_command_identify_from_client
4645 silc_server_command_identify_from_server
4647 * Disabled route cache adding because adding two different ID's with
4648 same IP replaces the old cache entry thus giving wrong route.
4649 The entry->router->connection is always the fastest route anyway
4650 so route cache may not be needed. Of course, new routes maybe
4651 established after receiving the ID when the entry->router->connection
4652 might not be anymore the most optimal.
4654 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Add route cache for received ID for fast routing.
4658 * Added silc_server_packet_route to route received packet on router
4659 that is not destined to us.
4661 * Renamed silc_server_get_route to silc_server_route_get.
4663 * Added id_string and id_string_len fields into SilcServer to
4664 include encoded ServerID for fast comparing without excess
4665 encoding of the ID's.
4667 * Cleaned up WHOIS command on server side. Added following static
4670 silc_server_command_whois_parse
4671 silc_server_command_whois_check
4672 silc_server_command_whois_send_reply
4673 silc_server_command_whois_from_client
4674 silc_server_command_whois_from_server
4676 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4677 arguments in command replies. All command functions should be
4678 updated to use this macro.
4680 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Minor typo fixes on command reply handling on server.
4684 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added silc_server_command_add_to_channel internal routine to add
4687 the client to the channel after router has created the channel and
4688 sent command reply to the server.
4690 * Added generic silc_server_send_command to send any command from
4693 * Use static buffer with ID rendering instead of duplicating data.
4695 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Fixed a channel user mode bug when joining to a channel server gave
4698 everybody channel founder rights, oops.
4700 * We mark ourselves as the router of the incoming server connection
4701 if we are router ourselves. This way we can check in some packet
4702 sending functions whether it is locally connected server. For
4703 incoming router connections we put NULL.
4705 * For router sending packets locally means now always sending the
4706 packet cell wide; to local clients and local servers. For normal
4707 server sending packet locally means sending it to only local
4710 * Fixed the JOIN command to really work in router environment. If the
4711 channel is created it is always created by the router. Router is
4712 also responsible of making the initial joining to the channel,
4713 sending JOIN notify to the sending server and distributing
4714 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4715 does not exist server doesn't do anything else but forward the
4716 command to the router which performs everything.
4718 * Added silc_server_send_channel_key function to send the Channel Key
4721 * Added silc_server_create_channel_key to create new channel key. The
4722 channel key is now re-generated everytime someone joins or leaves
4723 a channel, as protocol dictates. Note: channel->key_len is the
4726 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4729 packet_receive.[ch] to separate packet sending and receiving
4730 routines. The server.[ch] now includes everything else including
4731 actual packet processing (writing and reading data) and other
4734 Renamed silc_server_private_message_send_internal to
4735 silc_server_send_private_message. The routine is still though
4736 used only to relay private messages as server does not send
4737 private messages itself.
4739 Renamed silc_server_new_channel to silc_server_create_new_channel
4740 and added new function sicl_server_new_channel that handles the
4741 incoming New Channel packet. Added also new sending function
4742 silc_server_send_new_channel to send New Channel Payload.
4744 * Added new function silc_server_notify to process incoming notify
4745 packet to the server/router. Server may then relay the notify
4746 to clients if needed.
4748 * Added new function silc_server_new_channel_user to process incoming
4749 New Channel User packet. Router will redistribute the packet and
4750 send JOIN notify to its local clients and locally connected servers
4751 if needed. Normal server will send JOIN notify to its local client
4752 on same channel when received this packet. Added also corresponding
4753 sending function silc_server_send_new_channel_user to sent the
4756 * Added boolean route argument to send_notif_to_channel and
4757 packet_send_to_channel functions to attempt to route the packet
4758 if it is TRUE and send only locally if it is FALSE.
4760 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * silc_server_replace_id now broadcasts the received replace ID
4763 packet if it is not broadcast packet already. The router must
4764 broadcast to inform other routers about changed ID.
4766 * Added backpointer to server's router into SilcServer context in
4767 silcd/server_internal.h.
4769 * Fixed silc_server_packet_broadcast to send correct broadcast
4772 * The channel key is now distributed to the local client as soon
4773 as it is received from the router (in router environment) so that
4774 no other packet may be sent for the channel until client has
4777 * silc_server_remove_channel_user now broadcasts the received
4778 Remove Channel User packet if it is not broadcast packet already.
4779 The router must broadcast to inform other routers about removed
4782 * Added users field into SilcPacketContext that is a reference count
4783 of the context. One can increase the reference count by calling
4784 silc_packet_context_dup which is now changed to just increase the
4785 reference count instead of duplicating the data. The reference
4786 count is decresed by calling silc_packet_context_free that will
4787 free the data after the reference count hits zero.
4789 For now on the packet context and everything allocated into it
4790 (including the raw packet from network) must be freed by calling
4791 the new silc_packet_context_free function. Added also new function
4792 silc_packet_context_alloc that must be used now to allocate the
4793 context. This also means that if a routine is asynchronous from
4794 silc_[client/server]_packet_parse_type the packet context must
4795 be duplicated by calling silc_packet_context_dup. Otherwise it
4796 gets free'd after silc_[client/server]_packet_parse_type returns.
4797 Also, one must remember that if packet is duplicated then its
4798 reference count must be decresed by calling the free function as
4799 many times as it was duplicated.
4801 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4802 from both client and server.
4804 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Made joining to a channel working in router environment.
4808 * Cleaned up JOIN command on server side and create function
4809 silc_server_command_join_channel internal routine to make the
4812 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Changed silc_command_pending list to SilcDList. Also, added
4815 `ident' field to SilcServerCommandPending structure to identify
4816 the reply and to call correct callback.
4818 Added silc_server_command_pending_check function to replace the
4819 corresnponding macro. The silc_command_pending list is not
4822 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4823 to set identifier to previously allocated Command Payload. It
4824 is used to set identifier for command when resending Command
4827 * Added silc_command_payload_encode_payload to encode Command
4828 Payload buffer from SilcCommandPayload structure.
4830 * Added silc_argument_payload_encode_payload to encode Argument
4831 payload buffer from SilcArgumentPayload structure.
4833 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Changed WHOIS command to support router connection on server side.
4836 The whois request is always sent to router unless the server is
4837 standalone server. After server has received the reply from the
4838 router will it send the reply to the client.
4840 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4841 broadcast received broadcast packet. The function is used only
4842 by router. The broadcast packet is always sent to the router's
4845 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4846 render given ID to printable string, for log files for example.
4848 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Made basic router to router connections working. At least they
4851 can now connect to each other but nothing really works the way
4852 they are supposed - yet.
4854 * Added new initiator token to RouterConnection configuration
4855 file in silcd/serverconfig.[ch]. It is used to tell whether we
4856 are the initiator to the remote router or whether we'll expect
4857 the other end to connect.
4859 * Moved registering of listener task to silc_server_init, hence
4860 the server starts listenning as soon as it is run, even if it
4861 does not have connections to other routers. Let's see how well
4864 * Changed default connection retry timeouts for more suitable in
4867 * Removed cipher and such arguments from silc_idlist_add_client
4868 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4869 Added new function silc_idlist_add_data to add the keys and stuff
4872 * Added SilcIDListData structure and added it to SilcClientEntry
4873 and SilcServerEntry as their first field in the structure. This
4874 way we can explicitly cast the ID entries to the SilcIDListData
4875 structure and get common data for the entries. In past, we had
4876 to first check what type of connection it is and then cast it to
4877 correct ID entry type. Now, we can directly cast the opaque
4878 pointer to the SilcIDListData (no matter what ID entry it actually
4879 is) and get the data needed.
4881 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4884 in some circumstances even if threre were timeout tasks, though not
4885 IO tasks, but tasks anyway. Now fixed.
4887 * Defined SilcServerConnection structure to hold connection specific
4888 stuff about directly connected servers and routers. The definition
4889 is currently in silcd/server_internal.h. I thought about having
4890 a bit more important role fro this struct but for now it is used
4891 only when connecting to other server (or router actually).
4893 * Added connecting retry support in server when connecting to
4894 router(s). The retry feature implement exponential backoff
4895 algorithm. Also, added SilcServerParams structure to hold default
4896 parameters for server. For now, it include these retry settings
4897 and are hard coded. After server is moded to be as Silc Server
4898 Library this structure will be more important.
4900 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Changed client librarys channel->clients table to SilcList and
4903 changed code accordingly.
4905 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Changed client's channel table to SilcList and changed code
4908 accordingly. Also changed SilcChannelClientEntry to include back-
4909 pointer to the channel so that client entry can use that structure
4910 as list as well and we have fast cross-reference to the channel.
4911 This change dramatically decreased the complexity of channel
4912 handling with client entry and vice versa (removed one extra
4913 loop when searching for channel entry from many functions).
4915 * Changed server->sim from table to SilcDList and changed code
4918 * NAMES command can now be used from user interface. It will show
4919 the user list on the channel, neatly.
4921 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4922 Code now saves realname of the user if it becomes available.
4924 * Renamed configure.in to configure.in.pre and made ./prepare
4925 script to automatically add correct version string to
4926 configure.in which it creates from configure.in.pre.
4928 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * NAMES command reply now shows users mode with the nickname when
4933 * Moved silc_client_ch[u]mode[_char] functions from
4934 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4935 place sucks, they are utility functions and should be in some
4938 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4940 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4943 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Added TRQ (efficient deque and list library) into lib/trq. This is
4948 a very good list library that is currently used in the SILC. Defined
4949 SilcList API over the library because I didn't like the API very
4950 much. See lib/trq/silclist.h for the API and examples of how to
4951 use the API. Fixed various places in the code to use the new
4952 SilcList API. The SilcList is meant for lists that has a structure
4953 already defined as a list. It is not suitable to add just some
4954 context to the list (in TRQ, the context is the list actually).
4956 So, I defined SilcDList that can be used for the purpose where
4957 predefined list structure does not exit. This can be used as
4958 such list. Now some context just can be added to the SilcDList.
4959 Currently this list is not used in the SILC just yet, though there
4960 are a lot places where this can replace dynamically allocated
4961 tables and I will fix these places, later, to use SilcDList.
4962 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4963 and use TRQ internally).
4965 Also fixed some annoying warning messages that the original TRQ
4966 code generated. Also minor changes to TRQ's Makefile.in.
4968 * Added support for querying by Client ID to both WHOIS and
4969 IDENTIFY commands into server, as required by the protocol.
4971 * Removed method function pointers from SilcBuffer structure. They
4972 weren't used to anything and just increased the context size for
4973 no good reason. This change also made silc_buffer_alloc and
4974 silc_buffer_free functions inline functions.
4976 * Disabled command flooding detection support until it's fixed so
4977 that it accepts commands in but does not execute them more than once
4980 * Added silc_net_localhost(), to return local hostname, into
4981 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4982 that must be initialized before calling silc_client_init.
4984 * Added new function: silc_server_send_notify_on_channels to send
4985 notify messages to all channels client has joined. It is assured
4986 that the message is sent only once per client.
4988 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4989 lib/silcutil/silcutil.[ch] as silc_format function. The new
4990 function is generic and is used by server as well, not only by
4991 the logging routines.
4993 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4994 the provided version string was not acceptable. Added new function:
4995 silc_ske_check_version into lib/silcske/silcske.h. The function
4996 must be implemented by the application (client or server) and it
4997 does not reside in the SKE library. The function checks the version
4998 string remote end sent.
5000 * Added back pointers (to opaque context and to SilcSocketConnection)
5001 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5003 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5004 duplicate packet context structure.
5006 * Changed `notify' client operation to send same arguments as client
5007 receives from server except for ID's. ID's are mapped to correct
5008 ID entry and that is returned. Also, if channel entry is not sent
5009 by server but the notify is for channel the channel entry is sent
5010 to application (otherwise application doesn't know that it is for
5011 channel (library gets it from packet's Destination ID)).
5013 * Added silc_client_remove_from_channels into client library to
5014 remove a client from all channels it has joined to. Used when
5015 received SIGNOFF notify from server. Added also new function
5016 silc_client_replace_from_channels to replace old ID entry with
5017 new ID entry on all channels. Used when received NICK_CHANGE
5020 * Fixed ID Cache list handling in silc_idlist_get_client in
5021 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5022 to get (or query) client by ID.
5024 * Updated TODO list.
5026 * Added connection authentication status message defined by the
5027 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5028 support for these into the code in client and server side.
5030 * Added generic function silc_client_send_command to send any command
5031 with variable argument list. Application should use this function
5032 to send commands if the command functions provided by the library
5033 does not suite for the application's user interface needs.
5035 * Added new `failure' client operation. Application is notified about
5036 received failure packet if client is executing a protocol. In this
5037 case the protocol's execution has failed.
5039 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5040 is required by the protocol.
5042 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5043 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5046 * Added status flag to SilcSKE object to indicate realtime status
5047 of the SKE protocol.
5049 * Application receives now exactly same command reply arguments as
5050 the library receives from server. However, if ID is received the
5051 corresponding ID entry is returned to the application (eg. Client
5052 ID is mapped to correct SilcClientEntry entry and that is returned).
5053 Changed command_reply client operation due to this change.
5055 * Changed all ID's in commands and in command replys as ID Payloads.
5056 Change affected both client and server side codes.
5058 All ID's sent in SILC network (with execption of ID's in SILC
5059 Packet header) are sent in ID Payload to support variable length
5062 * Server now notifies nick changes and notifies all clients on
5063 the channels about the new nickname (about the new Client ID,
5066 * Implemented CMODE command to change channel modes. Supports all
5067 channel modes defined by the protocol specs except ban and invite
5068 lists. (Also, private channel key mode is supported but support for
5069 setting private channel key in client is missing, thus, this mode
5070 has no effect on client side (except that server requires that the
5071 client uses private channel key and normal channel traffic does not
5074 Also, invite mode works per se, but INVITE command does not work
5075 yet correctly, so you can set channel as invite only channel but
5076 inviting clients to the channel does not work (it is yet to be
5077 thought what's the best way to do it).
5079 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5080 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5081 Implemented CUMODE command to change user's mode on the channel.
5082 Supports all modes defined by the protocol specs.
5084 * Added NAMES command reply to return users modes on the channel.
5086 * Removed unnecessary and slow ciphers from lib/silccrypt.
5088 * Set SO_KEEPALIVE option to connection sockets by default.
5090 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5092 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5093 redefined the Notify Payload into protocol specs.
5095 * Added silc_id_payload_parse_id to get ID directly from raw
5098 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5101 accept searching by Client ID as well.
5103 * Added support for LEAVE and SIGNOFF notify types in client library.
5105 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5106 to parse ID Payload from raw data.
5108 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Added flags parameter into silc_ske_assemble_security_properties
5111 function in lib/silcske/silcske.[ch].
5113 * Changed notify client operation to fit better for notify messages
5114 sent by server. The notify payload received from server is now
5115 passed to the application (after parsing it to SilcNotifyPayload).
5116 It is application's responsibility to retrieve the arguments
5117 from the payload and show the message the way it wants. The message
5118 sent by server is implementation specific.
5120 * Changed public keys to comply with the protocol specification.
5121 Old public keys are not supported anymore and are not compatible.
5123 * Removed nickname from Channel Payload as the latest draft removed
5124 it. The client must resolve the nickname from the NAMES command
5125 reply received when it joined the channel.
5127 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5129 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Fixed some errors in protocol specification drafts.
5133 * Created lib/silccore/silcnotify.c to implement Notify Payload
5134 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5135 generic payloads described by protocol specifications. The file
5136 includes implementations for ID Payload and Argument Payload.
5138 * Changed Command Payload implementation to use the new Argument
5139 Payload. Changed command_xxxx_payload to command_payload_xxxx
5140 to comply with SILC coding conventions.
5142 * Added suppport for Argument Payload handling in Notify Payload
5143 implementation as protocol requires it. Added the new support
5144 into server and client lib as well.
5146 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added support for multiple nicknames on same channel. [n] is
5149 added locally to the nickname if there are more than one same
5150 nicknames on the channel.
5152 * Server now sends all nicknames that matched WHOIS request.
5153 Client also shows the list received from server.
5155 * Added TOPIC command to client side. User can now set and show
5156 current topic on channel.
5158 * Added MOTD command to client and server. Also, server sends the
5159 motd when client connects to the server.
5161 * Changed version strings to comply ISO 8601.
5163 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Fixed protocol error handling in client library. It should now
5166 cope even if the SKE fails for some reason.
5168 * Made new protocol specification drafts for submitting to IETF.
5170 * Implemented TOPIC command to server in silcd/command.c.
5172 * Added two new notify types into lib/silccore/silcnotify.h:
5173 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5174 notify nickname change and topic setting/change on a channel.
5176 * API change of command_reply operation in client library. The
5177 application gets now the status type received from server as well.
5179 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5183 * Cras fixed and optimized the packet handling even further and
5184 it should work now. Minor change to the prototype of function
5185 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5187 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added new function into lib/silcutil/silcschedule.[ch]:
5190 silc_schedule_with_fd to select() a specified fd. The function
5191 returns after timeout expires or data arrives or goes. The
5192 function is used by packet routines to wait that all data is
5193 received from network.
5195 * Fixed data reading from network in lib/silccore/silcpacket.c.
5196 The code now assures that all data is read from the fd and then
5197 continues packet processing. This was a bug fix since the code
5198 used to drop some data in some circumstances.
5200 * Added new function into lib/silcclient/client.[ch]:
5201 silc_client_start_key_exchange to start key exchange after
5202 connection has been established to server. The code internally
5203 now uses this funtion but its main purpose was to provide it
5204 for applications that perform their own connecting. After
5205 application has created a connection it merely calls this
5206 function to start the key exchange between client and server.
5207 The library takes care of everything else after that.
5209 Updated also lib/silcclient/README to explain the usage of
5212 * Do not send to application information that connection has
5213 been established. Application gets notified it by connect
5216 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5218 * Applied cras's patch to add silc_schedule_one function. The
5219 function runs scheduler once and returns.
5221 * Fixed the scheduler after cras messed it up. The timeout
5222 handling works now as it's supposed to work.
5224 * Added into lib/silccore/ silcnotify.h to include notify
5225 message types support. Changed silc_server_send_notify*
5226 functions, in server.[ch], to support those new notify types.
5227 Added the support for the notify types into client library,
5228 as well. Added new notify client operation into ops.h in
5231 * Changed silc_server_packet_send_to_channel to send normal
5232 packets instead of just channel message packets. The function
5233 is now used to send the notify packets to channels. It is not
5234 used to send channel message packets anymore, as server never
5237 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5238 va_arg()s as it seems to require it nowadays. I guess, if SILC
5239 is compiled with older va_arg() the new code should work anyway.
5241 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Splitted core library. Core library (lib/silccore) includes
5244 now only SILC protocol specific core (and common) components.
5245 Created new utility library (lib/silcutil) that includes more
5246 generic purpose stuff. The stuff for util library was taken
5247 from the old core library. This was minor and easy split.
5249 * Created SILC Client Library (lib/silcclient) that includes
5250 implementation of the SILC client without user interface. This
5251 was major move from silc/ directory. The code has been changed
5252 so that it is transparent towards the user interface. The
5253 silc/ directory includes now the same user interface as before
5254 and it uses the new client library. Read lib/silcclient/README.
5255 Basicly, the client library performs everything else related
5256 to SILC except user interface handling. Also, configuration
5257 files are considered to be part of user interface and library
5258 does not handle them.
5260 This change also changed a lot of structures, function naming etc.
5261 Most important change was that SilcClientWindow object was
5262 renamed to SilcClientConnection in the client library. Created
5263 also new file lib/silcclient/ops.h. Also added new files
5264 silc/local_command.[ch] and silc/client_ops.[ch].
5266 All these changes were made to make it easier for user interface
5267 designers to create what ever user interface for the SILC client
5270 It is also expected that the server will be moved to lib
5271 directory as well and SILC Server Library will be created;
5272 sometimes in the future.
5274 * Removed Local commands from lib/silccore/silccommand.h as
5275 they are application specific and new client library does not
5276 handle any of those anymore.
5278 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5279 old client implementation in silc/.
5281 * Added support for callback functions in SILC_LOG_* macros.
5282 Application can now set its own callbacks that will be called
5283 instead of using the default functions that will always print
5284 the debug messages to stderr (or stdout). Also, debugging can
5285 now be disabled by setting silc_debug to FALSE and re-enabled by
5286 setting it to TRUE. Note, that logging will still work even
5287 if debugging is disabled.
5289 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5290 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5291 silc_log_reset_debug_callbacks.
5293 * To enable debugging in silc client one must give now -d
5294 option on command line.
5296 * Changed silc_schedule_init to automatically allocate task queues
5297 if they are not allocated before calling it.
5299 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Added GMP 3.1 into math library.
5303 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5306 a channel in SILC network. The packet is used by servers and
5307 routers to notify other routers that user has left a channel.
5308 This little feature was missing until now. Added the feature
5309 to protocol specification as well.
5311 Added functions: silc_server_send_remove_channel_user and
5312 silc_server_remove_channel_user into server.[ch].
5314 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5315 lib/silccore/silcpacket.h. However, they are not implemented
5318 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Fixed joining to a channel and sending channel messages
5321 between server and router. The channel message sending should
5322 now work inside a cell.
5324 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Fixed the private message sending between server and router.
5327 The private message sending should now work inside a cell.
5329 * Added silc_server_replace_id into server.[ch] to replace
5330 existing ID in the SILC network.
5332 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5333 and silc_idlist_replace_server_id into idlist.[ch] in server.
5335 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Fixed the server to server connections. Server can again now
5338 connect to router. Router to router connections probably does
5341 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Added dynamic protocol registering support. Now protocols can
5344 registered and unregistered on the fly. Patch by cras.
5346 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Added lib/contrib directory to hold routines that some platforms
5349 don't have but are needed by SILC.
5351 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5352 into lin/contrib to provide getopt() and getopt_long() for
5353 those who don't have it.
5355 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Added AWAY command to client. When away message is set and
5358 client receives a private message packet the client automatically
5359 replies to the sender with the away message.
5361 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5362 bug seemed to be the cause of recent problems when compiling
5365 * Added version detection support to SKE protocol specification
5366 and added the new changes to the SKE implementation as well.
5367 There were other minor changes in the SKE protocol as well.
5369 Many changes in lib/silcske/silcske.[ch] and in
5370 lib/silcske/payload.[ch].
5372 * Added ^U functionality, clear input line. Patch from cras.
5374 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Mainly small bugfixes on core library. Fixed some debugging
5377 logging and buffer overflow in silclog.c.
5379 * Updated config.sub and config.guess on the distribution tree.
5381 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Added command lagging support in server. Client may execute
5384 commands now only once in two seconds.
5386 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Optimized packet reception. MAC computation and checking is now
5389 also more optimized. A lot previously duplicated code is now
5390 used as generic by both client and server.
5392 * Fixed key pair generation in clientutil.c
5394 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Added into lib/silccore/silcbufutil.[ch] new function;
5397 silc_buffer_realloc.
5399 * Moved generic packet sending/encryption functions to
5400 lib/silccore/silcpacket.[ch] from client and server. Some
5401 rewriting of the functions.
5403 * Moved all generic packet reception/decryption functions to
5404 lib/silccore/silcpacket.[ch] from client and server. The
5405 packet processing is now much cleaner in both client and server.
5406 These were major changes in both client and server.
5408 * Created many common functions in server to do packet sending.
5409 Previously code were duplicated a lot, this has been removed
5412 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Rewrote major parts of the ID cache system. Don't know
5415 whether it is better now or not but at least the API is more
5418 * Major rewrite on ID cache stuff on client because of the ID
5419 cache API changes. Added idlist.c to client.
5421 * Also major rewrite on ID cache stuff on server as well.
5422 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5423 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5424 in hand, instead they are all put into the ID cache system now.
5425 All server_idlist_* routines uses ID cache now instead of
5426 traversing its own lists (those lists does not exist anymore).
5427 SilcIDList though still exists. Also, SilcXXXEntry's are

5432 * Finally made the SKE implementation compliant to the protocol
5433 specification. All mp integers are now binary encoded as
5434 opposed being HEX encoded.
5436 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5439 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5440 functions: silc_[encode/decode]_pem. Also added function
5441 silc_encode_pem_file to PEM encode with newlines ('\n') for
5444 * SILC public keys are now encoded either PEM or binary. Same
5445 option is for private keys as well. By default private keys
5446 are binary encoded and public keys PEM encoded. Silly HEX
5447 encoding were removed.
5449 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5450 function to create fingerprints.
5452 * Fixed a bug in SHA1; does not change the original data anymore.
5454 * Partly implemented INFO command on client and server side.
5455 Fixed CLEAR command. Changes to SERVER command; show current
5456 server(s) when giving command without arguments. Added
5457 VERSION command to client.
5459 * Added check to server that unregistered connections cannot
5460 execute commands (unless it is specificly allowed).
5462 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Fixed screen refresh.
5466 * Fixed channel joining bug from client. On some circumstances
5467 client tried to join to a channel it had already joined.
5469 * Added public key verification process into client's protocol.c.
5470 The client now verifies the public key from user and saves
5471 it into ~./silc/serverkeys/ directory.
5473 Added into: clientutil.[ch]: silc_client_verify_server_key.
5475 * Changed SKE protocol's silc_ske_initiator_finish function
5476 to accept callback function that verifies the received public
5477 key. Removed old silc_ske_verify_public_key function.
5479 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5482 silc_pkcs_private_key[_data]_set.
5484 * Made the password and public authentication more cleaner in
5485 server's protocol.c.
5487 * Removed historic and obsolete protocol `channel_auth' from
5488 both client and server.
5490 * Removed wrong way of sending command status messages from
5491 server to client in server's command.c. The old way violated
5492 protocol specification.
5494 Changes to silccore/silccommand.[ch]: removed
5495 silc_command_encode_status_payload -> not needed anymore,
5496 changed silc_command_encode_payload_va to accept extra
5497 argument on variable argument list. The argument type must
5498 now be provided to the function. Also, added new function:
5499 silc_command_encode_reply_payload_va which is same as
5500 normal command_encode_payload_va except command status type
5501 is provided as extra argument.
5503 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Added ~./silc directory handling. The directory includes the
5506 public and private keys for the client.
5508 Added silc_client_check_silc_dir, silc_client_create_identifier
5509 and silc_client_load_keys.
5511 * Implemented SILC protocol compliant public key. Added public
5512 and private key saving to and loading from files.
5514 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5515 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5516 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5517 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5518 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5520 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5521 silc_pkcs_load_[public/private]_key.
5523 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added silc_server_get_route (route.[ch]) to get connection
5526 data for the fastest route for given ID.
5528 * Implemented INVITE command on client and server. The command
5529 were re-defined in the SILC Protocol Specification and the
5530 implementation now complies with the specification.
5532 * Implemented PING command on client and server.
5534 * Implemented NAMES command on client and server. The server side
5535 supports currently only normal server not router server yet.
5536 Some changes to NAMES definition in SILC protocol specification.
5538 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Implemented LEAVE command on client and server.
5542 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5543 again. This change was made to the protocol as well. Server
5544 should not violate the protocol specification anymore.
5546 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5549 was tested. SOCKS4 was not but should work anyway.
