1 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Assure that router cannot reroute the same channel message
4 to the sender. Affected file silcd/packet_receive.c.
6 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
8 * Made better checks that the channel message is not sent
9 to the router it came from. Affected file is
10 silcd/packet_send.c. Fixed memory leak too.
12 * Announce informations for incoming router connection, but
13 only after checking if it is replaced by backup router.
14 Affected file silcd/packet_receive.c.
16 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
18 * Fixed the backup resuming protocol to work in multiple
19 router environment. Affected file silcd/server_backup.c.
21 * Route packet only to one router in the function
22 silc_server_packet_send_to_channel. Affected file is
25 * Fixed silc_server_send_notify_dest to set the broadcast
26 flag. Fixed the silc_server_send_notify_topic to actually
27 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
28 Affected file silcd/packet_send.c.
30 * Changed the SFTP Filesystem interface. Changed the
31 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
32 the filesystem operation function. The SilcSFTPFilesystem
33 is now a context that is allocated by all filesystem allocation
34 functions and it already includes the operations structure
35 and filesystem specific context. It is given as argument
36 now to the silc_sftp_server_start. This made the interface
37 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
38 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
40 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
42 * Changed the backup router adding and getting interfaces
43 in the server. The router that will be replaced by the
44 specified backup router is now sent as argument. Affected
45 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
48 * Added silc_net_addr2bin_ne to return the binary form of
49 the IP address in network byte order. Affected files
50 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
52 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
54 * Check for existing server ID in silc_server_new_server
55 and in silc_server_connect_to_router_final and remove the
56 old entry if it exists. Affected file silcd/packet_receive.c,
59 * Send the channel message always to only one router, either
60 in upstream or downstream. Affected file is
63 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
65 * Wrote the definition of the backup resuming protocol to the
66 protocol specification.
68 * Removed one redundant channel key generation from normal
69 server during joining procedure. Removed one redundant
70 channel key sending from server to router during joining
71 procedure. Affected file silcd/command.c.
73 * Made minor bugfixes to the backup router resuming protocol.
74 Affected file silcd/server_backup.c, server.c.
76 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
78 * Added --disable-asm configuration option. Affected files
79 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
82 * Implemented the backup resuming protocol that is used to
83 resume the primary router position in the cell after the
84 primary router comes back online. Affected files
85 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
86 and silcd/server_util.[ch].
88 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Sleep two (2) seconds after sending QUIT command to server.
91 Affected file lib/silcclient/command.c.
93 * Assure that if outgoing data buffer is pending do not force
94 send any data. Affected file silcd/packet_send.c.
96 * Assure that if outgoing data buffer is pending do not force
97 send any data. Affected file lib/silcclient/client.c.
99 * Implemented the backup router support when the primary router
100 goes down. The servers and routers can now use the backup
101 router as new primary router without loosing connectivity.
103 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
105 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
106 in the server to indicate disabled entry. All data read
107 from the connection will be ignored and no data is sent
108 for entry that is disabled. Affected files are
109 silcd/idlist.h, silcd/server.c.
111 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
113 * Created SFTP client and server test programs in the
114 lib/silcsftp/tests directory.
116 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Implemented memory filesystem (virtual filesystem) for
119 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
122 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
124 * Implemented the SFTP (SSH File Transfer Protocol) to the
125 lib/silcsftp. It includes SFTP client and SFTP server
128 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Moved lib/silccore/silcprotocol.[ch] to the
131 lib/silcutil library.
133 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
134 take variable argument list pointer as argument. Affected
135 file lib/silcutil/silcbuffmt.[ch].
137 * Added silc_buffer_set function that is used to set data
138 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
139 Affected file lib/silcutil/silcbuffer.h.
141 * Changed various routines in the core library to use the new
142 silc_buffer_set instead of allocating new buffer only for
145 * Added 64-bit value formatting and unformatting support to the
146 silc_buffer_[un]format routines. Affected file is
147 lib/silcutil/silcbuffmt.[ch].
149 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
150 to includes/bitmove.h.
152 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Fixed channel user mode saving in client library. Affected
155 file lib/silcclient/command[_reply].c.
157 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
159 * Defined the file transfer to the SILC Protocol. Added
160 new packet type SILC_PACKET_FTP and defined File Transfer
161 Payload. The mandatory file transfer protocol is SFTP
162 (SSH File Transfer Protocol). Affected file in addition
163 of the internet draft is lib/silccore/silcpacket.h.
165 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
166 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
167 is used as part of backup router protocol when the primary
168 router of the cell is back online and wishes to resume
169 the position as primary router.
171 * Redefined the MAC generation keys in the protocol. The
172 same key is not used anymore in both direction. Both
173 direction will now use different keys for sending and
174 receiving. This fixes a potential security flaw. This
175 change causes incompatibilities in the protocol.
177 * Redefined also the MAC computation from the packet.
178 An packet sequence number is now added to the MAC
179 computation. This prevents possible replay attacks against
180 the protocol. This change too causes incompatibilities
183 Added `sequence' field to the SilcPacketContext to hold
184 the current sequence number for the packet.
186 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
188 * Added `created' field to the SilcIDListData in the file
189 silcd/idlist.h to indicate the time when the entry was
192 * Added `created' field to the SilcChannelEntry too. Affected
195 * Added `creation_time' aguments to all the announcement functions
196 in the server. If it is provided then only the entries that
197 was created after the provided time frame are actually
198 announced. Affected file silcd/server.[ch].
200 * The protocol says that the Channel ID's IP address must be
201 based on the router's IP address. Added check for this in
202 the silc_server_new_channel when processing incoming New Channel
203 Payload. Affected file silcd/packet_receive.c.
205 * Print out the correct version with --version in SILC client.
206 Affected file irssi/src/silc/core/silc-core.c.
208 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
210 * Fixed WHOWAS command to check for completnes of the client
211 entry always, not just when the command is coming from client.
212 Affected file silcd/command.c.
214 * Added new function silc_server_packet_queue_purge to purge the
215 outgoing data queue to the network. After the function returns
216 it is guaranteed that the outgoing packet queue is empty.
217 Affected file silcd/packet_send.[ch].
219 * Purge the outgoing packet queue in the rekey protocol's final
220 callback to assure that all rekey packets go to the network
221 before quitting the protocol. Affected file silcd/server.c.
223 * Added silc_client_packet_queue_parse as similar function as
224 in server to the client library. The affected file is
225 lib/silcclient/client.c.
227 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
229 * Splitted silcd/server.c and created silcd/server_util.[ch]
230 for utility functions.
232 * Added new socket flag SILC_SF_DISABLED to indicate that the
233 connection is open but nothing can be sent to or received from
234 the connection. Affected file lib/silcutil/silsockconn.[ch].
235 The checking for disabled socket is checked in the low level
236 silc_socket_write and silc_socket_read functions.
238 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
240 * Allow only nicknames and channel names that fits into the
241 7-bit unsigned char ASCII set. Affected file silcd/command.c.
243 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
245 * When processing JOIN command reply in server check that if
246 the channel exists in our global list we'll move it the local
247 list. Affected file silcd/command_reply.c.
249 * Fixed the check whether client is joined on the channel already
250 in JOIN command. Affected file lib/silcclient/command.c.
252 * Fixed the JOIN command reply to check whether the channel
253 already exists. Affected file lib/silcclient/command_reply.c.
255 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
257 * Added silc_ske_status_string to map the SKE error numbers
258 to readable strings. The affected files are
259 lib/silcske/silcske[_status].[ch].
261 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
263 * Do not show the private channels on the WHOIS channel list
264 as it is not allowed by the protocol. The affected file is
267 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Assure that the packet length digged from the actual packet
270 is something sensible in the silc_packet_decrypt_rest_special
271 in lib/silccrypt/silcpacket.c.
273 * Free and NULL the allocated pointer in silc_hmac_alloc if
274 the HMAC allocation fails. The affected file is
275 lib/silccrypt/silchmac.c.
277 * Print the selected security properties to the log files in
278 the server. Affected file silcd/protocol.c.
280 * Add SKE's reference counter even if calling the completion
281 callback manually. Otherwise it goes negative, although it
282 does not cause any problems. The affected file is
283 lib/silcske/silcske.c.
285 * Remove the client entry with short timeout after giving the
286 KILL command. Affected file lib/silcclient/command.c.
288 * Fixed to send error reply in WHOIS and IDENTIFY commands in
289 case all found clients are already disconnected (WHOWAS would
290 found them) in the server. Affected file silcd/command.c.
292 * Update the last_receive (time of last data received) to be
293 updated only when received private or channel message so that
294 the idle time showed in WHOIS makes more sense.
296 * Added boolean field `valid' in to the SilcClientEntry in the
297 client library to indicate whether the entry is valid or not.
298 This fixes the nickname change bug on channel when changing
299 the nickname to be same than the old (like nick to Nick) the
300 nickname formatter doesn't set the new nick anymore to Nick@host.
301 Affected file lib/silcclient/idlist.[ch].
303 * Now actually fixed the nickname changing on disconnection.
304 Added new function silc_change_nick to the Irssi SILC Client.
305 Affected file irssi/src/silc/core/client_ops.c,
306 irssi/src/silc/core/silc-nicklist.[ch].
308 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Check that the public key exists in the GETKEY command before
311 trying to encode it. Affected file silcd/command.c.
313 * Print some notifications on received public keys with GETKEY
314 command in the Irssi SILC Client. Affected files are
315 irssi/src/fe-common/silc/module-formats.[ch],
316 irssi/src/silc/core/client_ops.c.
318 * Use IDENTIFY command to resolve the server information in the
319 GETKEY command instead of INFO command. Affected file
320 lib/silcclient/command.c.
322 * All command reply functions in the client library now calls
323 the pending command reply callbacks even if an error has
324 occurred. The server has done this a long time and now it was
325 time to move the client library to this as well. Now all
326 errors can be delivered back to the pending command reply
327 callbacks if necessary. Affected files are
328 lib/silcclient/command[_reply].[ch].
330 * Change the nickname on disconnection back to the username
331 because in reconnect the server will enforce it to it anyway.
332 Affected file irssi/src/silc/core/silc-servers.c.
334 * Fixed a config file parsing bug in the Irssi SILC client.
335 Affected file irssi/src/silc/core/clientconfig.c.
337 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
339 * When printing the channel mode on JOIN, verify that the
340 channel key and channel's HMAC are valid. Affected file
341 irssi/src/silc/core/client_ops.c.
343 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
345 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
346 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
347 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
349 * Removed channel key rekey task deleting from the function
350 silc_server_save_channel_key. Affected file silcd/server.c.
351 Added explicit timeout task context instead that is used to
352 delete the task if we are registering a new task before the
353 new task has elapsed.
355 * When channel key rekey occurs the client library now saves
356 the old channel key for a short period of time (10 seconds) and
357 is able to use it in case some is still sending channel
358 messages encrypted with the old key after the rekey. Affected
359 file lib/silcclient/[idlist.h|client_channel.c].
361 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Added check to the silc_server_new_id_real to not accept
364 new ID if it is the sender's own ID. Affected file is
365 silcd/packet_receive.c.
367 * Assure that we do not announce ourself or the one we've
368 sending our announcements when we're router and are announcing
369 servers to our primary router. Affected file silcd/server.c.
371 * Fixed silc_server_command_identify_check_client to assemble
372 correct WHOIS packet. It send corrupted WHOIS packet and
373 caused problem with router to router connections. Affected
374 file silcd/command.c.
376 Fixed also silc_server_command_whois_check the same way
377 as for the IDENTIFY command.
379 * Added new SilcIDListStatus to the server in the SilcIDListData
380 structure. The status now includes the current status of
381 the entry (like registered, resolved etc.). Affected file
382 silcd/idlist.[ch]. Defined a bunch of different status types
383 as well. This replaced the old boolean registered field as well.
385 Added resolve_cmd_ident field to the SilcClientEntry structure
386 too so that if the entry is for example being resolved so
387 another command may attach to the same pending command reply
388 without requiring to resolve the same entry again. This concept
389 should optimize the WHOIS and the IDENTIFY resolving under
390 heavy load by taking away unnecessary resolving for entries
391 that are being resolved already.
393 Added support for adding multiple pending commands for one
394 command idenfier. Affected file silcd/command[_reply].[ch].
396 * Fixed WHOIS and IDENTIFY save to remove the cache entry
397 before deleting the data. Otherwise the hash table will have
398 freed data in comparison functions. Affected file is
399 silcd/command_reply.c.
401 * Fixed silc_idlist_replace_client_id to add the new entry to
402 the cache with NULL nickname. Otherwise there will be invalid
403 memory as the nickname after the nickname is freed. Affected
404 file silcd/packet_receive.c.
406 * Fixed the silc_idlist_get_clients_by_hash. The entries was
407 saved into wrong slots because the previous number of entries
408 was not taken into account. Affected file silcd/idlist.c.
409 Fixed same thing in silc_idlist_get_clients_by_nickname too.
411 * If we are router and we receive JOIN notify to a channel that
412 does not have any users then notified client is marked as the
413 channel founder, as it is it. The affected file is
414 silcd/packet_receive.c
416 * Added to the extended hash table API's table_del_*ext functions
417 the destructor as argument too, so that the caller can decide
418 which destructor to use or whether to use destructor at all.
419 Affected file lib/silcutil/silchashtable.[ch].
421 * Fixed ID Cache purging. It actually deleted the entries from
422 the hash table after the data was freed. The hash table ended
423 up comparing freed memory. The affected file is
424 lib/silccore/silcidcache.c.
426 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Fixed Irssi SILC client's KILL command's HELP syntax.
430 * The USERS command now resolves the detailed user information
431 if the userinfo field is missing. Affected file is
432 lib/silcclient/command_reply.c.
434 * Do not print error in silc_file_read if the read file does
435 not exist. Just silently return NULL. Affected file is
436 lib/silcutil/silcutil.c.
438 * Fixed the silc_log_output to not wine about NULL filename
439 and to not create some bogus " " filename. Affected file is
440 lib/silcutil/silclog.c.
442 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
444 * Fixed various printing bugs on the user interface in the
445 Irssi SILC Client. Minor changes that were forgotten from
448 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
450 * Fixed the configure.in.pre and the compilation and distribution
451 environment to support the new autoconf 2.52. That version is
452 now required to compile the CVS trunk.
454 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
456 * Renamed function silc_parse_nickname to silc_parse_userfqdn
457 to generally parse user@fqdn format strings. Affected file
458 lib/silcutil/silcutil.c.
460 * Added nickname_format and nickname_force_format fields to the
461 SilcClientParams structure. The first one defines the format
462 for the nicknames that the library will enforce if the receives
463 multiple same nicknames. The second one is boolean value and
464 can be used to force the library to always enforce the format
465 to the nicknames regardles whether there are multiple nicknames
466 or not. This configurable formatting was employed to flexibly
467 support accessing multiple nicknames from the user interface.
468 The userinterface can now set the nicknames to what ever format
469 they prefer. Affected file lib/silcclient/silcapi.h.
471 Added function silc_client_nickname_format to the file
472 lib/silcclient/idlist.c. It performs the nickname formatting.
474 Added new field `hostname´ to the SilcClientEntry context.
475 It holds the hostname of the client. Affected file is
476 lib/silcclient/idlist.h.
478 * Irssi SILC Client sets the nicknames in nick@hostn format.
479 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
480 irssi/src/silc/core/silc-core.c.
482 The WHOIS printing now also shows both the real nickname and
483 the formatted nickname so that user knows how to access the
484 user if there are multiple same nicknames cached. Affected
485 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
486 printing formatting too to take the hostname now as a separate
487 argument. The Affected file is
488 irssi/src/fe-common/silc/modules-formats.[ch].
490 * Changed the silc_client_get_clients_local to accept the formatted
491 nickname as argument. It accepts the real nickname too but the
492 formatted nickname can be used to find the true entry from
493 multiple entries. Affected file lib/silcclient/silcapi.h and
494 lib/silcclient/idlist.c.
496 * Added nickname_format_parse field to the SilcClientParams.
497 It is a callback function provided by the application to parse
498 the nickname out of the formatted nickname string. The library
499 calls it to get the nickname from the formatted string. Since
500 the application generally knows better the format of the nickname
501 string it parses it instead of the library, even though library
502 encodes the formatted string. If the callback function is not
503 provided then the library will use the string as is. The
504 affected file is lib/silcclient/silcapi.h.
506 * All the nickname strings passed to the client library in
507 commands are now expected to be formatted nickname strings.
508 If the command does not support the formatted nickname string
509 it will assume that the sent string is the actual nickname.
510 Affected file lib/silcclient/command.c.
512 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
514 * Added public key authentication support to OPER and SILCOPER
515 commands in the client library. Affected file is
516 lib/silcclient/command.c.
518 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
520 * Changed the get_auth_methdod client operation to be asynchronous.
521 It can be async if the application resolves the authentication
522 method from the server during the negotiation. Added new
523 SilcGetAuthMeth completion callback that the application will
524 call after resolving the authentication method.
526 Added function silc_client_request_authentication_method that
527 the application can use to resolve the authentication method
528 from the server. Added also SilcConnectionAuthRequest callback
529 that the library will call after the server has replied. The
530 application can call this function if it does not know the
531 current authentication method.
533 Affected files are lib/silcclient/client.c and
534 lib/silcclient/silcapi.h.
536 * The Irssi SILC client now automatically resolves the authentication
537 method incase any configuration information is not present (and
538 currently there never is). The affected file is
539 irssi/src/silc/core/client_ops.c.
541 * Fixed public key authentication from the client library.
542 Affected file lib/silcclient/protocol.c. Changed also the
543 protocol specification about the public key authentication in
544 the connection authentication protocol. The actual data to be
545 signed is now computed with a hash function before signing.
547 * Fixed the public key authentication from the server as well.
548 Affected file silcd/protocol.c.
550 * Removed the mlock()'s from the memory allocation routines.
551 Affected file lib/silcutil/silcmemory.c. The ./configure does
552 not check anymore for the mlock(). Affected file is
555 * Fixed USERS command in server to allow the execution of the
556 command for private and secret channels if the client sending
557 the command is on the channel. Affected file silcd/command.c.
559 * Fixed silc_client_get_clients_local to return the clients
560 count correctly. It could return wrong value. Affected file
561 lib/silcclient/idlist.c.
563 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
566 types. The assembler optimizations seemed not to like 64-bit
567 data types. The assmebler optimizations thus are now enabled
568 also for BSD systems as opposed to only enable them for Linux.
570 * Do not check for threads at all on BSD systems. Affected
571 file configure.in.pre.
573 * Removed -n and -h options from the Irssi SILC Client since
574 they are not used in silc.
576 * Fixed the prime generation to assure that the first digit
577 of the generated random number is not zero since our conversion
578 routines does not like number strings that starts with zero
579 digit. If zero digit is seen the random number is regenerated.
580 This caused some corrupted RSA keys when the zero first digit
581 was met. Affected file lib/silcmath/silcprimegen.c.
583 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
585 * Fixed WIN32 configuration in the ./configure script.
586 Fixed to include xti.h on environments that has it.
587 Patches by Carsten Ilchmann and andrew.
589 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
591 * Changed the silc_id_create_client_id to be collision
592 resistant. It is now assured that there cannot be created
593 two same client ID's. I suspect that some weird bugs in
594 the server were actually caused by duplicate Client IDs.
595 Affected file silcd/serverid.[ch]. A router receiving
596 new ID now also assures and informs the sending server
597 if the ID caused collision.
599 * Changed the silc_id_create_channel_id to also assure that
600 there are no collisions.
602 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Statement about ignoring the Mutual Authentication flag when
605 performing rekey with PFS was a bit misleading. It is ignored
606 if it was set in the initial negotiation, it cannot be even
607 set in the rekey. Fixed in the ke-auth draft. Started the
608 new versions of the protocol drafts in the doc/.
610 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
612 * Fixed a bug in silc_client_command_identify_save when saving
613 new channel information. The channel name was no duplicated
614 and caused crash on exit. Affected file is
615 lib/silcclient/command_reply.c.
617 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Fixed the getkey command handling in the server. Send just
620 empty OK reply to the sender if the key could not be fetched
621 (but everything else was ok, like the key just was not available).
622 Changed the public key parameter to optional in the protocol
623 specs so that empty OK reply can be sent. Affected file
626 Added a message to Irssi SILC client to tell to user if the
627 server did not return a public key.
629 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
631 * Fixed a channel key regeneration bug. It registered new
632 timeout tasks exponentially until all system resources were
633 used. Affected file silcd/server.c.
635 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Added the SILC Document generator to the scripts/silcdoc.
638 It can be used to generate the Toolkit Reference Manual out
639 of the source tree. Internally it will also use the RoboDoc
640 generator now imported in util/robodoc.
642 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Added couple of return's in rekey protocol if error orccurred
645 during the protocol. The execution must be terminated.
646 Affected file silcd/protocol.c. Also, terminate the protocol
649 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
651 * The client's Client ID was created initally from the wrong
652 nickname (it could have been in format nick@host) in the
653 silc_server_new_client. Affected file silcd/packet_receive.c
655 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
657 * Added some SILC_LOG_ERROR's to various error conditions
658 if client could not be added to ID cache. Affected files
659 silcd/packet_receive.c and silcd/server.c.
661 * When client's sock->user_data is freed, NULL also the
662 client->router and client->connection pointers. Added check
663 for these pointers being NULL to various places around the
664 code. Affected file silcd/server.c.
666 * Added client->data.registered == TRUE checks to various
667 places around the code to assure that unregistered client's
668 are not handled when it is not allowed. Affected file
671 * Added `bool registered' fields to all
672 silc_idlist_[server|client]_get_* routines to indicate whether
673 the fetched client needs to be registered or not. Affected
674 file silcd/idlist.[ch].
676 * Add your own entry as registered to the ID cache in the
677 server. Affected file server.c.
679 * Fixed a bug in silc_server_new_server. The SilcServer was
680 set as the new server's context instead of SilcServerEntry.
681 This naturally caused some weird bugs.
683 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
685 * Do not delete the channel rekey task when adding it
686 for in silc_server_create_channel_key.
688 * Changed the silc_server_create_channel_key to return
689 TRUE or FALSE to indicate the success of the channel key
692 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
694 * Fixed MSVC++ project files and added missing files to
695 Makefiles under win32/.
697 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
699 * Do not add TCP_NODELAY flag if the operating system
700 does not have it defined. Affected files are
701 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
703 * Fixed buffer overflow from Irssi SILC Client. Affected
704 file irssi/src/fe-common/core/themes.c.
706 * Fixed double free in client library in the file
707 lib/silcclient/client.c when disconnecting from server.
709 * Applied double free patch from cras to Irssi SILC client.
710 Affected files irssi/src/core/[modules/expandos].c
712 * Fixed the disconnection handling to Irssi SILC Client.
713 The application must call silc_client_close_connection
714 in ops->connect client operation in case of failure of
715 the connection. Affected file is
716 irssi/src/silc/core/client_ops.c.
718 * Do not set sock->protocol to NULL in the function
719 silc_client_close_connection after executing the protocol's
720 final callback since the sock might not be valid anymore.
721 Affected file lib/silcclient/client.c.
723 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
725 * Do not enable SILC_THREADS if the linking with libpthread
726 did not happen. Affected file configure.in.pre.
728 * Added notion to protocol specification that server must
729 verify the sent authentication payload with CMODE when
730 setting the channel founder key. Implemented it to the
731 server. Affected file silcd/command.c.
733 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Added _EXTRA_DIST SILC distribution variable to the
736 distributions file. It is used to conditionally add extra
737 files or directories to the specific distribution. Affected
738 files ./prepare, Makefile.am.pre and distributions.
740 Removed the `_' from the start of the distribution names.
743 * Added README.WIN32 for instructions to compile the Toolkit
746 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
748 * Fixed a double free in disconnection in the server. Affected
749 file is silcd/server.c.
751 * Fixed the lib/silcske/groups.c to work now also with GMP
752 MP library. The string conversion did not work when using
753 specific base and the base is indicated in the string as well.
755 * Created win32/ directory which now includes MSVC++ specific
756 stuff so that toolkit (DLLs) may be compiled with MSVC++.
757 It will appear only in the toolkit distribution
759 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
761 * Changed the key material distribution function in case when
762 the hash output is too short. The data is now concatenated
763 a bit differently than it used to. Made the change to the
764 SKE protocol specification.
766 * Added better GMP detection to configure.in.pre. A patch
769 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Fixed a minor bug in SKE that might cause some problem on
772 some platforms. Affected file lib/silcske/silcske.c.
774 * Added the cookie checking for initiator in the SKE. It checks
775 that the responder returns the sent cookie unmodified. The
776 affected file is lib/silcske/silcske.c. Added new SKE
777 error type INVALID_COOKIE that can be sent during the
778 negotiation. Fixed some memory leaks as well.
780 * Added the "invalid cookie" error message to Irssi SILC client's
783 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
785 * Added `task_max' field to the SilcClientParams to indicate
786 the maximum tasks the scheduler can handle. If set to zero,
787 default values are used. Affected file lib/silcclient/silcapi.h.
789 * Fixed memory leaks in silc_client_close_connection. Affected
790 file lib/silcclient/client.c.
792 * Added silc_client_del_client_entry to client library to free
793 all memory of given client entry. Affected file is
794 lib/silcclient/idlist.[ch].
796 * Added new functions silc_client_del_channel and
797 silc_client_del_server to delete channel and server entries.
798 Affected file lib/silcclient/[silcapi.h/idlist.c].
800 * Removed silc_client_del_client_by_id from silcapi.h.
802 * Fixed the INFO command to return the server's own info
803 correctly when querying by Server ID. Affected file is
806 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
808 * Removed the non-blocking settings in WIN32 code in the
809 silc_sock_[read/write] and added SleepEx instead. Affected
810 file lib/silcutil/win32/silcwin32sockconn.c. The availability
811 of input data is now checked with FIONREAD and ioctlsocket.
813 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Call silc_schedule_task_del_by_context in the
816 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
817 Affected file lib/silccore/silcprotocol.c.
819 * Call silc_protocol_cancel for active protocols in the
820 silc_server_close_connection if the funtion
821 silc_server_free_sock_user_data has not been called.
822 Affected file silcd/server.c.
824 * Generic tasks cannot be deleted using the del_by_fd
825 task deleting function since generic tasks does not match
826 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
828 * Added a notion to SILCOPER help file that the SILCOPER works
829 only on router server, not on normal server.
831 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
833 * Added for WIN32 support for the new scheduler as well.
834 Affected file lib/silcutil/win32/silcwin32schedule.c.
836 * Fixed the SHA1 implementation to work on various platforms.
838 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
841 API. It is part of the scheduler now. Everything else is
842 as previously but some functions has changed their names.
843 Checkout the lib/silcutil/silcschedule.h for the interface.
844 Updated all applications to use the new interface. Affected
845 files are lib/silcutil/silcschedule.[ch].
847 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Found a bug in the SKE implementation. The HASH value,
850 specified by the protocol, was not computed correctly. The
851 public key of the responder was not added to the computation
852 even though it is mandatory. Affected file lib/silcske/silcske.c.
853 This unfortunately causes incompatibilities with older
856 * Added WIN32 specific network init and uninit functions:
857 silc_net_win32_init and silc_net_win32_uninit to init and uninit
858 the Winsock2. Affected file lib/silcutil/silcnet.h and
859 lib/silcutil/win32/silcwin32net.c.
861 * Set the socket always to nonblocking mode on WIN32 after
862 reading data or writing data. Affected file is
863 lib/silcutil/win32/silcwin32sockconn.c.
865 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Fixed various compilation problems under WIN32. Affected
868 files lib/silcutil/win32/silcwin32thread.c and
869 lib/silcutil/win32/silcwin32schedule.c.
871 * Removed all _internal.h #includes from public header
872 files. Internal headers must never be included from
875 Removed also the lib/silcske/payload_internal.h file.
877 * All include files that may be needed (public and some others
878 included by the public headers) by application developers are
879 now copied to the ./includes directory. It does not copy any
880 internal headers. Affected file Makefile.defines.pre and all
881 Makefile.am's under lib/ and subdirs.
883 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Do not change the ~/.silc directory's permissions automatically.
886 Affected file irssi/src/silc/core/clientutil.c.
888 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Do not cancel the protocol in silc_server_close_connection
891 it might cause recursion. Now cancelled in the function
892 silc_server_free_sock_user_data. Affected file silcd/server.c.
894 * Fixed the silc_server_remove_clients_by_server to regenerate
895 the channel keys correctly finally. Added also new function
896 silc_server_remove_clients_channels to actually do it.
897 Affected file silcd/server.c.
899 * Fixed the silc_server_new_channel to not crash by giving
900 wrong router to the new channel. Affected file is
901 silcd/packet_receive.c.
903 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
905 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
906 which is given as argument to the silc_client_alloc now.
907 It can be used to configure the client and set various parameters
908 that affect the function of the client.
910 * The USERS command in server did not check whether the channel
911 is private or secret. Affected file silcd/command.c.
913 * Added new argument to the USERS command in protocol specification.
914 The USERS command now can take the channel name as argument
915 as well. Added support for this in client and server and
916 updated the protocol specs.
918 * Completed the GETKEY command in client. It can be now used
919 to fetch also servers public key not only some clients.
920 Affected files lib/silcclient/command[_reply].c.
922 * Added silc_client_get_server to return server entry by the
923 server name. Affected files lib/silcclient/silcapi.h and
926 * Redefined the IDENTIFY command in protocol specification to be
927 more generic. It now can be used to query information about
928 any entity in the SILC Network, including clients, servers and
929 channels. The query may be based either the entity's name
930 or the ID. Added support for this in both client and server.
932 Affected files silcd/command.c and lib/silcclient/command.c
935 * Optimized the WHOIS and WHOWAS commands in the server. Removed
936 the _from_client and _from_server functions. Affected file
939 * Added silc_client_get_channel_by_id_resolve to the file
940 lib/silcclient/silcapi.h to resolve channel information by
941 its ID. Added also silc_client_get_channel_by_id that
942 does not resolve it from the server.
944 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Added SilcServerEntry context into the client library
947 to represent one server. The INFO command now allocates
948 these to save the resolved server info. For now on the
949 client library will also keep information about servers,
950 connected and resolved with INFO.
952 The INFO command now allocates the SilcServerEntry context
953 and saves the server info there. The COMMAND_REPLY in
954 the INFO now returns the parameters to application in
955 same order as defined in the protocol specification.
957 The entries are cached in the client->server_cache.
959 * The INFO command is now issued after received the Client ID
960 from the server. Affected file lib/silcclient/client.c.
962 * The CMODE_CHANGE notify may now return also an SilcServerEntry
963 to the application as the mode changer might be server.
964 It is guaranteed that NULL is not returned anymore to the
965 application. Affected file lib/silcclient/client_notify.c.
967 The ID Type is now also passed to the application so that
968 it can check whether the returned entry is SilcClientEntry
971 Added new function silc_client_get_server_by_id to return
972 the server entry by ID. Affected files are the
973 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
975 * Do not create the channel in the Irssi SILC Client when issuing
976 the JOIN command but when received the sucessful JOIN command
977 reply. Otherwise the channel might get created even though we
978 could not join it. The Affected file is
979 irssi/src/silc/core/[silc-channels.c/client_ops.c].
981 * Fixed a channel joining bug in router. The router must also
982 check the channel modes, invite and ban lists etc. when serving
983 the JOIN command sent by normal server. Affected file is
984 silcd/command.c. The router now resolves the client's
985 information from the server who sent the JOIN command if it
986 does not know it, and processes the JOIN command only after
989 * Changed the SilcCommandCb to take new argument; void *context2.
990 Affected file lib/silccore/silccommand.h
992 The second argument in the command callbacks in the server now
993 includes the SilcServerCommandReplyContext if the command was
994 called as pending command callback from the command reply.
995 Otherwise it is NULL. When called as pending the status of the
996 command reply will be checked and if it was erronous the
997 error will be sent to the original sender of the command.
998 This way the client always receives the error messages even
999 though the server was actually the one who received the error
1000 when it resent the command to router, for example. Affected
1001 files silcd/command[_reply].[ch].
1003 * Fixed sending WHOWAS command's error message to client if
1004 the requested client could not be found. It was missing.
1007 * Changed the CMODE and CUMODE commands reply arguments in the
1008 protocol specification. The Channel ID is now sent in both
1009 of the commands to identify the channel. Implemented this
1010 new feature to the client and server. Affected files
1011 lib/silcclient/command_reply.c and silcd/command.c.
1013 * Made better checks for invite and ban lists in the JOIN
1014 command in server. Affected file silcd/command.c.
1016 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * The server now performs the incoming host IP/DNS lookup
1019 using the silc_socket_host_lookup and thus does not block
1020 the server anymore. Affected file silcd/server.c.
1022 * Completed the multi-thread support for SILC Scheduler in
1023 the lib/silcutil/silcschedule.c.
1025 * Fixed the configure.in.pre to detect the pthread correctly
1028 * Fixed a deadlock in silc_task_queue_wakeup in the file
1029 lib/silcutil/silctask.c.
1031 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * Added new function silc_schedule_wakeup that is used in
1034 multi-threaded environment to wakeup the main thread's
1035 schduler. It needs to be used when a thread adds a new task
1036 or removes a task from task queues. After waking up, the
1037 scheduler will detect the task queue changes. If threads
1038 support is not compiled in this function has no effect.
1039 Implemented the wakeup mechanism to both Unix and WIN32
1040 systems. Affected files are lib/silcutil/silcschedule.[ch],
1041 lib/silcutil/unix/silcunixschedule.c and the
1042 lib/silcutil/win32/silcwin32schedule.c.
1044 * Added new function silc_task_queue_wakeup to wakeup the
1045 scheduler by the specified task queue. Affected file
1046 lib/silcutil/silctask.[ch].
1048 * The silc_socket_host_lookup_start now wakes up the scheduler
1049 after adding the timeout task. Affected file is
1050 lib/silcutil/silcsockconn.c.
1052 * The silc_socket_host_lookup is synchronous now if the threads
1053 support is not compiled in. However, the callback is still
1054 called asyncronously through the scheduler, anyway. Affected
1055 file lib/silcutil/silcsockconn.c.
1057 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Added new function silc_socket_host_lookup to perform
1060 asynchronous IP and FQDN lookups for the socket connection.
1061 Affected files lib/silcutil/silcsockconn.[ch].
1063 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1066 that may or may not compile the mutex support in.
1068 Changed the silc_mutex_alloc interface. It allocates the
1069 mutex now to the sent pointer and returns TRUE or FALSE.
1071 Affected file lib/silcutil/silcmutex.h.
1073 * Wrote the SILC Task Queue interface to support multi-threads.
1074 Affected file lib/silcutil/silctask.[ch].
1076 * Wrote the SILC Scheduler to support multi-threads. Affected
1077 file lib/silcutil/silcschedule.c.
1079 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1082 in lib/silcutil/win32/.
1084 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Defined SILC Mutex API and SILC Thread API and implemented
1087 them for Unix. Affected files are
1088 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1089 lib/silcutil/unix/silcunixmutex.c and
1090 lib/silcutil/unix/silcunixthread.c.
1092 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Fixed the silc_server_remove_clients_by_server's channel
1095 key re-generation. The hash table handling was incorrect
1096 and would not work with many channels. Affected file is
1099 * Fixed some memory leaks around the server code.
1101 * Rewrote the silc_server_get_users_on_channel to support IPv6
1102 based Client ID's. Affected file silcd/server.c.
1104 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1105 specification. However, a separate document must be written
1106 to define the detailed signing procedure and the payload
1107 associated with the flag. Defined the flag to the
1108 lib/silccore/silcchannel.h as well.
1110 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Changed the dynamic tables to static size tables in the
1113 lib/silccrypt/silchmac.c.
1115 * Removed GCC dependencies from the code. A patch by cras.
1117 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Do not show the error "Error receiving packet bla bla"
1120 in server if it really was not an error (-2 means that reading
1121 is pending). Affected file silcd/server.c.
1123 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Fixed a possible crash in silc_server_remove_clients_by_server
1126 in silcd/server.c. Fixed there also some memory leaks.
1128 * Fixed the silc_idlist_replace_client_id. It could replace
1129 wrong key in the hash table. Affected file silcd/idlist.c.
1131 * Do not check whether there are global users on the channel
1132 if the channel->global_users is FALSE. Affected functions
1133 silc_server_remove_from_one_channel and
1134 silc_server_remove_from_channels in silcd/server.c. Also,
1135 do not check if the removed client is local as we can be
1136 sure that global client was not removed from the channel
1137 and checking for global users is not needed.
1139 * The silc_server_remove_clients_by_server now re-generates
1140 the channel keys correctly for those channels that had
1141 clients removed from them. Affected file silcd/server.c.
1143 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1145 * Found the reason of random crashes in the server. We weren't
1146 ignoring the SIGPIPE signal (which can be sent in write())
1147 and it crashed the server. Affected file silcd/silcd.c.
1149 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * Assure that sock->user_data is not NULL in the function
1152 silc_server_packet_send in silcd/packet_send.c.
1154 * Disconnect the remote connection if it could not be added
1155 to any ID lists in the server. The affected file is
1158 * Check in silc_server_packet_send[_real/dest] that the
1159 socket is not disconnecting and ignore the data if it is.
1160 Affected file silcd/packet_send.c.
1162 * Define inline to __inline on native WIN32 compilation.
1163 Affected file includes/silcwin32.h.
1165 * Added some explicit type casts for inline code since MSVC
1166 require them. Affected files lib/silcutil/silcbuffer.h,
1167 lib/trq/silcdlist.h and lib/trq/silclist.h.
1169 * Print warning in log files from now on if the packet
1170 decryption fails. Affected file silcd/server.c.
1172 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Changed the `say' client operation's interface to accept
1175 new `type' argument to indicate the type of the message sent
1176 by the library. The application may filter the library's
1177 messages according the type. The affected file is the
1178 lib/silcclient/silcapi.h.
1180 * Added two new functions to lib/silcclient/silcapi.h:
1181 silc_client_del_client and silc_client_del_client_by_id.
1182 Affected file lib/silcclient/idlist.c.
1184 * Moved the clientincludes.h from includes/ to silc/ and
1185 serverincludes.h from includes/ to silcd/.
1187 * The modes for the CMODE and CUMODE are now passed as
1188 uint32 for application with COMMAND_REPLY. The affected
1189 file is lib/silcclient/command_reply.c.
1191 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * /WHOIS without arguments shows client's own information.
1194 Affected file lib/silcclient/command.c.
1196 * Changed PING to not accept any arguments. The specs
1197 says that client can ping only the connected server so
1198 requiring an argument is not needed. Affected file is
1199 lib/silcclient/command.c.
1201 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Fixed a fatal bug in private message sending and reception
1204 encryption and decryption when using private message keys.
1205 The implementation was incorrect and did not follow the
1206 specification. It causd that some of the message were
1207 lost since it did not use the sending and receiving keys
1208 as the protocol suggests. This has been fixed and will cause
1209 incompatibilities with older clients when sending private
1210 message encrypted with private message keys. Affected files
1211 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1212 and various other in Irssi SILC Client.
1214 Added `responder' boolean argument to the functions
1215 silc_client_add_private_message_key[_ske] to indicate when
1216 the key is added as responder or initiator of the key
1219 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * Removed the silc_ske_check_version function and created
1222 a SilcSKECheckVersion callback. Added also a function
1223 silc_ske_set_callbacks that is now used to set all SKE
1224 callbacks. The callback functions are not given to
1225 the SKE functions anymore, but this function is used to
1228 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1230 * Added `silc_version' argument to the silc_client_alloc
1231 to define the version of the application for the library.
1232 The library will use the version string to compare it
1233 against the remote host's (usually a server) version
1234 string. Affected file lib/silcclient/silcapi.h
1236 * Added the KE protocol context to Key Agreement context
1237 in client library so that we can abort the SKE if it
1238 is in process when we get timeout. Affected file is
1239 lib/silcclient/client_keyagr.c.
1241 * Do not resolve the client ID forever if it returns in the
1242 first time that such client does not exist. This was done
1243 for example with private message. Affected file is
1244 lib/silcclient/client_prvmsg.c.
1246 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1248 * Do not add regex.h for WIN32. The affected file
1249 includes/silcincludes.h.
1251 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1252 not work yet 100%. It generates the DLL's automatically
1253 when compiling with --with-win32 under cygwin.
1255 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * lib/contrib/regex.c is not compiled on WIN32.
1259 * Added silc_net_get_socket_opt function to the
1260 lib/silcutil/silcnet.h.
1262 * Added includes/silcwin32.h for WIN32 specific includes
1265 * Do not use ptime structure or any of the posix process
1266 functions on WIN32 in lib/silccrypt/silrng.c.
1268 * Added silc_gettimeofday to provide generic function
1269 for struct timeval on all platforms. Added the function
1270 to lib/silcutil/silcutil.h.
1272 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1275 library as they clearly belong there. As a plus side we
1276 can make the actual socket connection routines platform
1279 Added also new generic function silc_socket_read and
1280 silc_socket_write (that used to be silc_packet_[read/write].
1281 The implementation of these are platform specific.
1283 * Added WIN32 specific routines of silc_socket_[read/write]
1284 to lib/silcutil/win32/silcwin32sockconn.c.
1286 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Added preliminary support for native WIN32 compilation under
1289 cygwin (using the -mno-cygwin option for GCC) to the
1290 ./configure.in.pre. The --with-win32 now prepares the
1291 compilation for native WIN32.
1293 * Rewrote the SILC Scheduler interface in the file
1294 lib/silcutil/silcschedule.h. The scheduler is now context
1295 based and does not have anymore any global static scheduler.
1296 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1297 and created lib/silcutil/win32 directory for WIN32 based
1300 * Added Unix specific network routines to the
1301 lib/silcutil/unix/silcunixnet.c and the old
1302 lib/silcutil/silcnet.c includes now only generic routines.
1304 Added WIN32 specific network routines to the
1305 lib/silcutil/win32/silcwin32net.c.
1307 * Added Unix specific utility functions from the
1308 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1310 * Added WIN32 SILC Scheduler to the file
1311 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1314 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Do not handle JOIN notify in the server if the target client
1317 is not registered (idata->registered == FALSE). The affected
1318 file is silcd/packet_receive.c.
1320 * Update the nickrec->founder in event_cumode in the Irssi SILC
1321 client. Affected file irssi/src/silc/core/silc-channels.c.
1323 * Fixed the CUMODE_CHANGE notify handling in the server when
1324 server and router are announcing their clients on channels.
1325 Now the mode changes are saved and notified correctly. The
1326 affected file is /silcd/packet_receive.c.
1328 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1329 They really did not replace the cache entry in the ID Cache.
1330 Now they do that. Affected file silcd/idlist.c.
1332 * Fixed the KICK notify handling in the Irssi SILC client to
1333 update the channel records so that the kicked client does not
1334 appear to be on the channel. The affected file is
1335 irssi/src/silc/core/silc-channels.c.
1337 * Always update the conn->current_channel when executing command
1338 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1340 * Fixed the KILL notify handling in Irssi SILC client to remove
1341 the killed client on all channels.
1343 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Fixed the silc_parse_command_line to remove extra spaces
1346 from the start and end of the arguments. Affected file is
1347 lib/silcutil/silcutil.c.
1349 * Cancel and free any active protocol in the function
1350 silc_server_close_connection. Affected file silcd/server.c.
1352 * Cancel and free any active protocol in the function
1353 silc_client_close_connction. Affected file is
1354 lib/silcclient/client.c.
1356 * Do not execute the KILL command for clients that are in
1357 history (ie. they are not in the network). Affected file is
1360 * Fixed KILL notify handling, client does not crash anymore.
1361 Affected file irssi/src/silc/core/silc-channels.c.
1363 * Reduced the default packet buffer size from 2048 to 1024 in
1364 lib/silccore/silcpacket.c.
1366 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1367 counter to the SKE context that is incresed when the SKE library
1368 performs async operation outside the library. If the outside
1369 process frees the SKE context and FREED status will be set
1370 and the library will detect after the sync operation that the
1371 libary is freed. The affected files are
1372 lib/silcske/silcske[_status].[ch].
1374 * Resolve the client entry information in the function
1375 silc_client_channel_message to assure that NULL pointer is not
1376 passed as client entry to the application. */
1378 * Fixed the task timeout calculation to assure that there is
1379 never negative timeouts. The affected file is
1380 lib/silcutil/silcschedule.c.
1382 * Fixed the channel user mode notification sending in server.
1383 It was sent point-to-point to the router (or to server by router)
1384 but it needs to be destined to a channel. The routines now
1385 supports sending the channel user mode notifys to the channels
1386 when announcing clients and channels. Affected files are
1387 silcd/server.c and silcd/packet_receive.c.
1389 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1390 It did not actually replace the old channel entry in the cache.
1391 Affected file lib/silcclient/client_notify.c.
1393 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Fixed a possible crash in silc_packet_send_prepare. It now
1396 assures always that there is enough space in the buffer and
1397 at the tail area of the buffer (for MAC).
1399 Fixed the inbound buffer reallocation in silc_packet_read.
1400 It was old code and did not handle the reallocation correctly.
1403 The affected file is lib/silccore/silcpacket.c.
1405 * Fixed buffer overflow in silc_parse_nickname in the file
1406 lib/silcutil/silcutil.c.
1408 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1410 * make install generates new server keys only if there is not
1413 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1416 Added check that if the NOREPLY is set then we will not send
1417 the away message. This avoids infinite loop of away messages
1418 if both clients are away. The affected file is
1419 lib/silcclient/client_prvmsg.c.
1421 * Fixed client crash if /NICK was given without arguments.
1422 Affected file lib/silcclient/command.c.
1424 * Server does not send the invite list in INVITE command back
1425 to the client if the list was not altered. Added this notion
1426 to the protocol spec as well. Affected file silcd/command.c.
1428 Fixed possible crash in INVITE command by checking the
1429 value of silc_server_get_client_route command.
1431 * Fixed the INVITE notify type handling. The arguments are now
1432 taken in correct order and client does not crash. The affected
1433 file is irssi/src/silc/core/silc-channels.c.
1435 Removed the "Inviting xxx to channel" message from the
1436 client library away and let the application handle it.
1437 Affected file lib/silcclient/command.c. Added that message
1438 to Irssi SILC client's message formats.
1440 * Fixed CMODE command crash in client. It now checks the
1441 amount of arguments correctly and does not crash. The affected
1442 file is lib/silcclient/command.c.
1444 * Do not create new channel automatically in silc_channels_join
1445 but check whether the channel by that name already exists.
1446 Affected file irssi/silc/core/silc-channels.c.
1448 * Do not send the SERVER_SIGNOFF to router if the disconnected
1449 entity was the router. Affected file silcd/server.c.
1451 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1452 SILC client as it was missing from there.
1454 Added the handling of the KICK notify to the Irssi SILC client
1455 as it was missing. Added "you have been kicked" message to
1456 Irssi SILC client's message modules formats.
1458 Added the handing of the KILL notify to the Irssi SILC client
1459 as it was missing. Added the kill message module formats
1462 The affected file is irssi/src/silc/core/silc-channels.c.
1464 * The router did not save the channel mode the server announced.
1465 Affected file silcd/packet_receive.c.
1467 * Fixed a possible crash in INFO command in server. If the
1468 server did not provide the server info it crashed. Affected
1469 file silcd/command.c.
1471 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Fixed the GETKEY command in the server to check also the
1474 global list. Otherwise the GETKEY would not work correctly
1475 in normal SILC server. Affected file silcd/command.c.
1477 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1479 * Fixed GETKEY crash, it crashed if the command did not succseed.
1481 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1484 is now real and not just an macro interface to GMP.
1486 Removed the entire GMP from the source tree and imported new
1487 NSS MPI library instead. Reason for removing GMP is that it is
1488 extremely large and compiles extremely slow. The NSS MPI
1489 is only a few files and compiles in less than 10 seconds.
1490 The speed is also about the same as GMP. The MPI is imported
1491 to lib/silcmath/mpi.
1493 If the system has GMP installed we will still use the GMP.
1494 If it is not then the NSS MPI will be compiled.
1496 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Merged a long nickname (127 characters long) crash bugfix from
1499 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1501 * Merged a freed memory reference bugfix from Irssi CVS tree.
1502 Affected file irssi/src/core/commands.c.
1504 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Added the server's public key sving and verification to the
1507 server when performing the SKE. This was missing and the
1508 remote server's (or router's) public key was accepted without
1509 checking whether we have it previously or trust it at all.
1510 Affected file silcd/protocol.c.
1512 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1514 * Check in the silc_server_timeout_remote if protocol is active
1515 and make sure that the protocol's final callback is called so
1516 that all memory if freed. Affected file silcd/server.c.
1518 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * silc_server_whois_send_reply crashed the server if the nickname
1521 was 127 characters long. Affected file silcd/command.c.
1523 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Added sanity check to the silc_server_new_client. If the hostname
1526 is provided inside username then check that the provided hostname
1527 really is the same as the resolved one. If the hostname was not
1528 resolved then check it from the public key. Affected file is
1529 silcd/packet_receive.c.
1531 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1532 if the server disconnected us and the connection is not valid
1533 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1535 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1536 the library to the lib/silcutil/silcutil.[ch].
1538 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * Close log file after open. Affected file
1541 lib/silcutil/silclog.c.
1543 * Check whether sock == NULL in silc_client_send_packet and return
1544 if it is. Affected file lib/silcclient/silcclient.c.
1546 * Check rec->entry == NULL in the Irssi SILC Client before
1547 sending the channel message. Affecte file is
1548 irssi/src/silc/core/silc-servers.c.
1550 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Merged a splitted window bugfix from Irssi CVS tree. The
1553 affected file is irssi/src/fe-text/textbuffer-view.c.
1555 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1556 It did not print nickname.
1558 * Improved the distributions system a bit.
1560 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1562 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1563 irssi/src/fe-text/gui-window.c.
1565 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1566 to in-active server. The affected file is
1567 irssi/src/silc/core/client_ops.c.
1569 * Resolve the client in USERS command reply if the entry does
1570 not have username resolved. The affected file is
1571 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1572 command to WHOIS command to really resolve stuff. The USERS
1573 is not used any more in any critical section so WHOIS can
1574 be used even though it might be slower than IDENTIFY.
1576 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1579 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Changed the protocol API a bit more consistent in the
1582 lib/silccore/silcprotocol.[ch].
1584 * Changed the following headers to ROBODoc format:
1586 lib/silccore/silcpayload.h
1587 lib/silccore/silcprotocol.h
1588 lib/silccore/silcsockconn.h
1590 All core library headers are now formatted.
1592 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Fixed a bug in Irssi SILC client; do not show that you are
1595 server/router operator if you really are not. Affected file is
1596 irssi/src/silc/core/client_ops.c.
1598 * Renamed silc_command_free_payload to silc_command_payload_free.
1599 Affected file lib/silccore/silccommand.h
1601 * Added silcmath.h to include the prototoypes of various routines
1602 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1605 * Changed the following headers to ROBODoc format:
1607 lib/silccore/silcchannel.h
1608 lib/silccore/silccommand.h
1609 lib/silccore/silcid.h
1610 lib/silccore/silcidcache.h
1611 lib/silccore/silcmode.h
1612 lib/silccore/silcnotify.h
1613 lib/silccore/silcpacket.h
1614 lib/silcmath/silcmath.h
1616 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Added checking to the server code not to start the server if
1619 ciphers and stuff are not configured properly. Affected files
1620 silcd/serverconfig.[h] and silcd/server.c.
1622 * Changed the layout of the header files of the public interfaces
1623 in the SILC libraries. The new layout supports ROBODoc
1624 documentation tool (and some others) so that it is easy to create
1625 a library reference manual. All the other headers and source
1626 code must still follow the CodingStyle document. Also source
1627 code must not include these ROBODoc stuffs, only the headers.
1628 Furthermore, all public interface headers must now be named
1629 by using `silc' prefix, example: silcapi.h, silccipher.h.
1630 Some files were renamed due to this. All the other headers
1631 must not be used as public interfaces. I will update the
1632 CodingStyle document later. Changed following headers, so far:
1634 lib/silcclient/silcapi.h
1635 lib/silccore/silcauth.h
1636 lib/silccore/silcprivate.h
1637 lib/silccrypt/silcdh.h
1639 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1643 * Removed silc_client_packet_send_flush from the client library
1644 as it is not needed. Affected file lib/silcclient/client.[ch].
1646 * Added printing of message of unresolved authentication method
1647 to the Irssi SILC client. Added it to the module formats.
1648 Removed the same message from the client library.
1650 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Added new distribution feature, DISTLABEL. Every distribution
1653 can define own preprocessor label that can be used in the
1654 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1655 file distributions, acconfig.h.pre and prepare.
1657 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Added Makefile.defines_int to include the actual definitions
1660 for Makefile.defines.in. Tested the new distribution system,
1661 created distributions and tested installation.
1663 * Added AWAY message printing to the Irssi SILC client. Added
1664 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1666 * Added SCONNECT command to call the SILC's CONNECT command.
1667 Cannot use CONNECT directly since Irssi uses that internally.
1668 Affected file irssi/src/silc/core/silc-servers.c.
1670 Added ACTION local command. It is same as ME command but takes
1671 the channel as mandatory argument.
1673 Rewrote some of the Irssi's help files to suite for SILC
1676 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1678 * Added Makefile.defines[.in] that should for now on be included
1679 in all Makefile.am file in the source tree. That file includes
1680 all common compilation definitions for SILC source tree.
1682 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Minor changes to the ./prepare script to change the package
1685 name according the distribution name to the configure.in.
1687 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Created new distribution system. Added file `distributions'
1690 that defines all the distributions that can be created out of
1691 the SILC source tree. The ./prepare script now reads that
1692 file to determine how to prepare the distributions. The
1693 first argument to the ./prepare is the name of the distribution
1694 and second is the version of the distribution. If given
1695 without arguments it creates the default (toolkit) distribution
1696 with the default version (defined in ./prepare).
1698 All Makefile.am files that are subject to the distributions
1699 are now named as Makefile.am.pre. These are ./Makefile.am
1700 and lib/Makefile.am. Others may be changed later.
1702 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Added invite list, ban list, some key management and connection
1705 error message printing to module formats in the Irssi SILC client.
1707 * Added new silc_client_set_away_message to set the away message
1708 that is back to the person who sent private message. The
1709 affected file lib/silcclient/silcapi.h and the
1710 lib/silcclient/client_prvmsg.c.
1712 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Fixed the private message sending in the Irssi SILC client,
1715 added local command KEY to the Irssi SILC client.
1717 Added key management and key agreement message formats to the
1718 irssi/src/fe-common/silc/module-formats.[ch].
1720 Added USERS (alias WHO) printing, server/router operator
1721 indication and LIST command printing to the module formats.
1723 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Fixed channel joining notify handling, cumode notify handling
1726 from Irssi SILC client.
1728 * Added SILC specific module-formats to the Irssi SILC client so
1729 that SILC specific message hilighting, colors etc is possible.
1730 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1732 Added channel mode, channel user mode, actions, notices,
1733 whois and whowas printing to the the module-formats.c.
1735 * Fixed a bug in channel deletion in the server. The channel
1736 is not left to the cache even if the channel founder auth mode
1737 is set when there are no users anymore on the channel. Affected
1738 file silcd/server.c.
1740 * The silc_net_localhost now resolves the entire hostname including
1741 the domain name. Affected file lib/silcutil/silcnet.c.
1743 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Changed the ask_passphrase client operation to be ascynchronous.
1746 It has now a completion callback and a context that the
1747 application must call after it has got the passphrase from
1748 the user. Affected files lib/silcclient/silcapi.h,
1749 lib/silcclient/protocol.c, lib/silcclient/command.c and
1752 Added SilcAskPassphrase callback that the application calls
1753 to deliver the passphrase to the library.
1755 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1756 The public key verification and especially a certificate
1757 verification is asynchronous procedure.
1759 Added new SILC_SKE_STATUS_PENDING status to indicate the
1760 request is pending and a callback will be called to finalize
1763 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1764 indicate that remote end did not send its public key (or
1765 certificate), even though we require it. Added check for this
1766 condition in the SKE. This was a security bug, now fixed.
1768 Defined new SilcSKEVerifyCbCompletion callback that is called
1769 when the verification process is completed.
1771 The affected files lib/silcske/silcske_status.h and
1772 lib/silcske/silcske.[ch].
1774 * Changed the verify_public_key client operation to be async
1775 as well. Defined SilcVerifyPublicKey callback that is used to
1776 indicate the success of the public key verification process.
1778 Changed the server and client to use the new async client
1781 * Changed the Irssi SILC client's internal scheduler to be called
1782 twice as many times as it used to be. As a result the client
1783 should be a bit faster now. Affected file is
1784 irssi/src/silc/core/silc-core.c.
1786 * Added support to Irssi SILC client of asynchronous public key
1787 verification and passphrase inquiry. Affected file is
1788 irssi/src/silc/core/silc-core.c.
1790 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Do not say "You have left channel %s" in client library.
1793 Moved it to the application. Affected files are
1794 lib/silcclient/command.c and silc/client_ops.c.
1796 * Fixed silc_client_get_clients. Command context was not
1797 duplicated and was freed memory in the callback. Affected
1798 file lib/silcclient/idlist.c.
1800 * Do not say "you are now talking..." on JOIN command in the
1801 client library. The appliation must handle it.
1803 * Do not say ".. changed topic to" in command reply in the
1804 client libary. The application must handle it.
1806 * Fixed TOPIC command sending in the client library.
1808 * Fixed a memory leak in silc_client_command_free in the file
1809 lib/silcclient/command.c.
1811 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Imported a modified version of Irssi client to the source tree.
1814 The Irssi will be used to create a new client called
1815 Irssi SILC. Imported to irssi/.
1817 Added silc_core_init_finish function to the Irssi. Affected
1818 file irssi/configure.in.
1820 A lot changes in the Makefile.ams around the irssi tree.
1822 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Do not rehash if the new size is same as the old size of the
1825 hash table, in the silc_hash_table_rehash*. The affected file
1826 lib/silcutil/silchashtable.c.
1828 * Replaced hash_table_del_by_context calls from the server
1829 (when channel->user_list and client->channels) to the
1830 hash_table_del as it is sufficient and faster.
1832 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Added silc_hash_table_list, silc_hash_table_get and the
1835 SilcHashTableList structure to provide an alternative way to
1836 traverse the hash table. The affected files are
1837 lib/silcutil/silchashtable.[ch].
1839 * Changed the server's idlist routines to use the hash table
1840 routines to optimize the code.
1842 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Replaced the client entry's `channel' list and channel entry's
1845 `user_list' list to hash tables for optimized lookup. Changed
1846 the code to use the hash table interface around the code.
1847 Affected file lib/silcd/idlist.[ch].
1849 * Added `auto_rehash' boolean argument to the function
1850 silc_hash_table_alloc to indicate whether the hash table should
1851 auto-rehash when it thinks is appropriate time. It will
1852 increase the hash table size if the there is twice as much
1853 entries in the table than the size of the table, and will
1854 decrease the size if there are twice as less entries than
1855 the size of the table.
1857 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1861 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1863 * silc_idcache_purge_by_context deletes the entry now by context
1864 as it is supposed to do. Affected file lib/silccore/idcache.c.
1866 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1867 client is not anymore valid (WHOWAS givens the info) and not
1868 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1870 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Removed the `data' and `data_len' arguments from the ID Cache
1873 interfaces and added `name' argument. ID Cache does not handle
1874 anymore the binary data only a names associated with given ID.
1876 * When hashing a Client ID with silc_hash_id the entire ID is
1877 not hashed anymore, instead only the hash of the Client ID is
1878 hashed. This way we can access the Client ID from the cache
1879 with Client ID but with the hash of the ID (which is a hash of
1880 the nickname) as well without any difference in performance.
1882 Added also silc_idcache_find_by_id_one_ext to do one on one
1883 searching when we have the actual ID. Added also function
1884 silc_hash_client_id_compare. The affected files are
1885 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1887 * When hashing the name associated with a ID it is always done
1888 in lowercase. This way we can access the cache without worrying
1889 about case-sensitivity, even though, for example nicknames are
1892 * Fixed a bug in server with channel message sending. It put
1893 wrong ID type as destination ID. The affected file
1894 silcd/packet_send.c.
1896 * silc_idcache_del_by_context now deletes from all hash tables
1897 by context. Affected file lib/silccore/idcache.c.
1899 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1901 * Changed the client library to use the new ID Cache interface.
1902 Changes around the source tree.
1904 * Added silc_hash_table_rehash_ext to rehash with specific
1905 hash function. Affected file lib/silcutil/silchashtable.[ch].
1907 * Added silc_hash_string_compare to compare two strings in the
1908 hash table. Affected file lib/silcutil/silcutil.[ch].
1910 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Added new function silc_idcache_del_by_context into the
1913 lib/silccore/idcache.[ch].
1915 * Changed the server's ID list routines to use the new ID Cache
1916 interface. Changes around the source tree.
1918 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Added silc_hash_table_del[_by_context]_ext functions in to the
1921 lib/silcutil/silchashtable.[ch].
1923 Removed silc_hash_table_find_all* routines and added new
1924 silc_hash_table_find_foreach to replace them.
1926 Added silc_hash_table_replace_ext function as extended
1927 replacing function. Separated the simple hash table interface
1928 from the extended hash table interface in the file
1929 lib/silcutil/silchashtable.h.
1931 * Fixed minor bugs and changed it to use some of the new
1932 hash table functions in lib/silccore/idcache.c
1934 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Added new function silc_hash_table_find_all to return all keys
1937 in the hash table by the specified key. As the hash table is
1938 collision resistant it also makes it possible to have several
1939 duplicate keys in the hash table. This function may be used to
1940 find all of the keys from the hash.
1942 Added user_context arguments to the SilcHashFunction,
1943 SilcHashCompare and SilcHashDestructor to deliver user specified
1946 Added new fuctions silc_hash_table_find[_all]_ext to do
1947 extended lookup with specified hash and compare functions and
1948 specified user contexts.
1950 Added new function silc_hash_table_add_ext to add the key
1951 with specified hash function and user context.
1953 Added new function silc_hash_table_foreach to traverse all
1954 entrys in the hash table. Added SilcHashForeach callback
1957 Added new function silc_hash_table_del_by_context to delete
1958 the entry only if the context associated with the key matches.
1960 Affected files are lib/silcutil/silchashtable.[ch].
1962 * Removed silc_hash_[server/client/channel]_id and added just
1963 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1964 silc_hash_id_compare to compare two ID's using as the hash table
1965 comparison function. Added also silc_hash_data to hash
1966 binary data and silc_hash_data_compare to compare it.
1968 * Removed silc_idlist_find_client_by_hash as it is not needed
1969 anymore. Affected file silcd/idlist.[ch].
1971 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1972 to use internally the SilcHashTable. The new ID Cache is a lot
1973 faster than the old one. Some of the ID Cache interface was also
1974 rewritten and obsolete and stupid functions were removed.
1976 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Added entry_count field to the SilcHashTable to keep the number
1979 of the entries in the table. Implemented the function
1980 silc_hash_table_rehash. Added new function
1981 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1983 Fixed a minor bug in silc_hash_table_free.
1985 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1986 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1987 into the lib/silcutil/silcutil.[ch].
1989 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Implemented a collision resistant hash table into the
1992 lib/silcutil/silchashtable[ch]. See the header and the source
1993 for the SilcHashTable API.
1995 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Merged dotconf version 1.0.2 into lib/dotconf.
1999 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Do not compile anything in lib/silcsim/* if the SIM support
2002 is not enabled. The tree should now compile without problems
2005 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Compiled the SILC under cygwin. Compiled and tested briefly
2008 without problems. More tests needed. The SIMs didn't compile
2011 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2013 * Fixed possible crash in silc_get_username in the
2014 lib/silcutil/silcutil.c.
2016 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Fixed a va_arg in silc/client_ops.c.
2020 * Oops, RC5 routines were named AES and caused some problems
2021 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2023 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Added new SilcIDIP structure into the lib/silccore/id.h and
2026 replaced the old `ip' fields from all SILC ID's to that type.
2027 This is a step towards IPv6 support.
2029 The silc_id_get_len takes now the ID as an extra argument.
2030 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2031 both IPv4 and IPv6 based ID's.
2033 The affected files are lib/silccore/id.[ch] and other files
2034 around the tree using these routines.
2036 * Removed the ID length arguments in server from various
2037 silc_server_send_notify_* routines -> they are not needed
2040 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2042 * Fixed memory leak in silc_encode_pem_file in the file
2043 lib/silcutil/silcutil.c.
2045 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Check minor version as well in the SKE. Affected files are
2048 silcd/protocol.c and lib/silcclient/protocol.c.
2050 * Added --identifier option to the server so that an identifier
2051 can be when creating the public key for the server. Affected
2052 file is silcd/silcd.c.
2054 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2055 lib/silccrypt/silcpkcs.c.
2057 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Register default ciphers and stuff when using -C option with
2060 the server. Affected file sildc/silcd.c.
2062 * Put back the servers public key filename format, it is better
2063 than the new one. For now, the client keys are saved with the
2064 new filename format. The affected file silc/client_ops.c.
2066 * Implemented the Cipher API for the rest of the ciphers that
2067 did not implement it or implemented it the wrong way.
2069 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Register default ciphers and stuff when using the -S option
2072 in the client. Affected file silc/silc.c. Same also when
2073 creating new key pair with -C option.
2075 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Fixed the silc_verify_public_key client operation function to
2078 save the public keys differently. The fingerprint is now
2079 used as filename and not the hostname. This way also the
2080 client keys are saved uniquely and not with hostnames. The
2081 affected file is silc/client_ops.c.
2083 * Trimmed the silc_hash_fingerprint function to remove extra
2084 whitespaces from the end of the fingerprint. The affected
2085 file is lib/silccrypt/silchash.c.
2089 * Added silc_cipher_register_default function to register all
2090 default ciphers. It can be used when configuration files
2091 does not exist and the application does not want any specific
2092 ciphers in any specific order.
2094 The SilcDList is now used as silc_cipher_list dynamically
2095 allocated cipher list. Removed the static list all together
2096 and now all ciphers must be allocated to the dynamic list.
2097 The silc_cipher_alloc routine was changed to check only the
2100 All silc_cipher_* routines that used to return int returns
2103 The affected files lib/silccrypt/silccrypt.[ch].
2105 * The same thing was done to silc_hash_* as for silc_cipher_*
2106 routines. Affected files lib/silccrypt/silchash.[ch].
2108 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2109 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2110 Added also silc_pkcs_[un]register[_default] functions.
2111 Removed the data_context from the PKCS API.
2113 * Added silc_hmac_register_default function to register default
2114 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2115 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2116 to unregister all hmacs at once.
2118 * Register the default ciphers, hash functions, PKCSs and HMACs
2119 if client's configuration file does not exist. The affected
2122 * The client did not load the hash functions from the SIM
2123 modules at all. Added support for this. Affected file is
2124 silc/clientconfig.c.
2126 * When decoding public key with silc_pkcs_public_key_decode, check
2127 the supported algorithm only if PKCS are registered. Affected
2128 file lib/silccrypt/silcpkcs.c. The same was done with the
2129 silc_pkcs_private_key_decode.
2131 * Fixed the SILC List routines to keep the list always in order.
2132 It used to change the list's order when traversing the list but
2133 not it preserves the order. Affected file lib/trq/silclist.h.
2135 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2137 * Added the client library to use the SilcSocketConnection's
2138 reference counter (by silc_socket_dup) to prevent the bug that
2139 the socket object may be freed underneath async operation.
2141 * The name resolv library checking fixes in the configure.in.pre.
2144 * Created new version of the protocol drafts for future
2145 development. The -03 drafts are the ones that will be changed
2146 in the trunk now and the -02 will remain as they are.
2148 * Send list of CUMODE notifys to the router when announcing
2149 the channel users to the router. Affected file silcd/server.c.
2150 If the router receiving channel founder CUMODE for a channel
2151 that already has channel founder it will send CUMODE notify
2152 to the sender to remove the channel founder rights from the
2153 announced client. Affected file silcd/packet_receive.c.
2155 * The CUMODE notify may now use Server ID as well as the entity
2156 who changes the mode. Updated protocool specs.
2158 * Updated INSTALL and README files.
2160 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * New web pages in the http://silc.pspt.fi. The pages was
2167 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Implemented the [DenyConnectin] config section in the server.
2170 Added silc_server_config_denied_conn to check whether incoming
2171 connection is denied. Affected file silcd/serverconfig.[ch].
2173 * Do not check the ports when checking the incoming configuration
2174 data if the port is 0, meaning any. Affected file is
2175 silcd/serverconfig.c.
2177 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Fixed buffer overflow in silc_string_compare in the file
2180 lib/silcutil/silcutil.c.
2182 * Fixed double free in silc_server_command_leave in the file
2185 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Fixed the version checking in the server. Affected file is
2190 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Fixed the configuration data fetching when accepting new
2193 connections in the server. Affected file silcd/server.c.
2195 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Added `sender_entry' argument to the function
2198 silc_server_packet_relay_to_channel so that we can check
2199 whether some destination actually belongs to the same route
2200 the sender belongs (ie, we must not resend the packet to the
2201 sender). Affected file silcd/packet_send.[ch].
2203 * Added `servername' field to the SilcClientEntry in the server
2204 to hold the name of the server where client is from. Affected
2205 file is silcd/idlist.h.
2207 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Moved the channel message encrypting in the router betwen
2210 router connections from silc_server_channel_message to the
2211 silc_server_packet_relay_to_channel since we want to check
2212 whether we have anybody channel before encrypting anything.
2213 Affected files silcd/packet_[receive/send].c.
2215 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Fixed the [AdminConnection] server config section to support
2218 multiple entries. Affected file silcd/serverconfig.c.
2220 * Added support into the server to check the validity of the
2221 incoming connection before executing any KE or authentication
2224 * The connection configuration is now saved to the KE and
2225 connection auth protocol contexts and not fetched anymore in
2226 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2228 * The local hosts listenning address and port is also resolved
2229 now when starting the server. We want to have the socket object
2230 to include the real address and port for the listener. Added
2231 new function silc_net_check_local_by_sock into the files
2232 lib/silcutil/silcnet.[ch].
2234 * Fixed a broadcast bug in server -> do not broadcast if we
2237 * Fixed a routing bug. Do not route broadcast packets ever.
2238 Broadcast packets must be processed always and not routed since
2239 they may be destined to some other host than yourself and thus
2240 would get routed without no good reason. Affected file is
2243 * Added function silc_server_config_is_primary_route to check
2244 whether primary router connection has been configured (a router
2245 configuration that we are initiating). If there is not, we
2246 will assume that there is only two routers in the SILC network
2247 and we will use the incoming router connection as our primary
2248 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2250 * Changed the order of the broadcasting. Broadcast _after_ the
2251 packet has been processed not before. Affected file is
2254 * Fixed a [ClientConnection] parsing bug. The port was never
2255 parsed correctly thus resulting to port 0. Affected file
2256 silcd/serverconfig.c.
2258 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2259 argument and did not set the broadcast packet flag. Affected
2260 file silcd/packet_send.c. Fixed same bug in the function
2261 silc_server_send_notify as well.
2263 * If we receive NEW_ID packet for our own ID in the server, ignore
2266 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Removed the nickname from the Private Message Payload.
2271 Updated the code and the protocol specs.
2273 * Updated protocol specs for submitting to the IETF.
2275 * Tweaked the Random Number Generator a bit. Affected file
2276 lib/silccrypt/silcrng.c. Exported a new function
2277 silc_rng_[global]_add_noise which can be used to add more
2280 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Do not parse packets with different timeout when protocol
2283 is active -> may cause problem with rekey. Affected file
2286 * When server receives signoff notify it must not create
2287 new channel key if the client is on any channels since the
2288 sender of the signoff notify will create it.
2290 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Added printing of error messages during SKE protocol from the
2293 failure packet sent by server during SKE. Affected file
2296 * Removed the client's failure_callback handling with timeout
2297 and handle it immediately when received.
2299 * The SKE library returned wrong type in SUCCESS and FAILURE
2300 packets. They must be 32 bit MSB not 16 bit MSB.
2302 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Ok, rewrote the logic of the re-key and now it seems to work.
2305 I tested it on high traffic with frequent re-keys without
2306 problems. Added hmac_receive (and renamed hmac to hmac_send)
2307 in SilcClientConnection in lib/silcclient/client.h and
2308 in SilcIDListData in silcd/idlist.h. Also, removed the
2309 SilcPacketParserContext's cipher and hmac fields as they are
2310 not needed anymore and actually caused some problems when
2311 the ciphers and hmac's changed underneath the packet parser.
2313 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * If re-key protocol is active then process the incoming packets
2316 synchronously since we must assure that icoming packets encrypted
2317 with the old key is processed before the new keys is set to
2318 use. This is true other packets than for REKEY packets.
2319 Affected file silcd/server.c. The same was done to client library
2320 as well, affected file lib/silcclient/client.c.
2322 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Fixed bug in client and server to accept the force send if
2325 the packet is send from silc_[server/client]_packet_process
2326 function. Otherwise the packets are never delivered, oops.
2328 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Disable force sending of packets when REKEY protocol is active.
2331 We must assure that no packet is sent directly when rekey is
2332 performed. All packets must be sent through packet queue.
2333 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2334 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2335 function is silc_[server/client]_packet_send_real to check
2338 * Replaced the SIM paths from example config files to
2339 /usr/local/modules. Also, make install creates now
2340 /usr/local/silc/logs directory to hold all the SILC server
2343 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Made the configure.in.pre work on Solaris. Patch by salo.
2347 * Made all ciphers compatible with non-x86 machines. Defined
2348 CBC mode macros into lib/silccrypt/ciphers_def.h.
2350 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Fixed the make install.
2354 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * When MAC computation fails the silc_packet_decrypt returned 0
2357 even though it was supposed to return -1. Fixed this. The
2358 affected file is lib/silccore/silcpacket.c.
2360 * Do not replace the config files in /etc/silc (in make install)
2361 if they already exist. Affected file ./Makefile.am.
2363 * Do not send re-key packets immediately but through packet queue.
2364 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2366 * Changed silc_net_check_host_by_sock to return FALSE if the
2367 IP/DNS could not be resolved. Though, it returns the IP address
2368 now even if it could not resolve it (but returns also FALSE).
2369 Affected file lib/silcutil/silcnet.[ch].
2371 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Added silc_pkcs_decode_identifier to decode the public key's
2374 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2375 Added also silc_pkcs_free_identifier. Added also new context
2376 SilcPublicKeyIdentifier.
2378 * Added -S option to the silc client. It is used to dump the
2379 contents of the specified public key file.
2381 * Changed the PKCS api to return the public key length when
2382 setting the public key.
2384 * Fixed a fatal bug in the public and private key file loading.
2385 Affected file lib/silccrypt/silcpkcs.c.
2387 * Execute the packet parsing for client with zero (0) timeout
2388 if the protocol is active. Affected file silcd/server.c.
2390 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Made the key generation options to the silcd program. Added
2393 -C option, equivalent to client's option.
2395 * Added new [ServerKeys] config section to the server. It
2396 configures the server's public and private key.
2398 * Defined generic Public Key Payload into the protocol
2399 specification to send specific type of public keys and
2402 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2403 public key or certificate.
2405 * Implemented the GETKEY command to the server and to the
2406 client library and on user interface.
2408 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Made preliminary `make install' work.
2412 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Added SilcServerRekey context into silcd/idlist.h.
2416 * Added the PFS support as defined in the specification to the
2417 SKE protocol. Affected files lib/silcske/*.c.
2419 * Added `ske_group' field to the SilcServerRekey context to hold
2420 the number of the SKE group that is used with PFS in re-key.
2421 Affected file silcd/idlist.h.
2423 * Added PFS re-key support to the server. Affected file is
2426 * Added silc_protocol_cancel to cancel execution of the next
2427 state of the protocol. Affected file is
2428 lib/silccore/silcprotocol.[ch].
2430 * Added the re-key support with and without PFS to the client
2431 library. Re-key is performed once in an hour, by default.
2433 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2434 Added silc_client_rekey_callback and silc_client_rekey_final.
2435 Affected files are lib/silcclient/protocol.[ch] and
2436 lib/silcclient/client.[ch].
2438 * Removed the `hmac_key' and `hmac_key_len' fields from the
2439 SilcClientConnection structure; not needed. Affected file is
2440 lib/silcclient/client.h.
2444 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Do not ask whether user wants to use the negotiated private key
2447 for private messages, just use it. Affected file is
2448 silc/local_command.c.
2450 * Added `send_enc_key' and `enc_key_len' fields to the
2451 SilcIDListData structure since they are needed in the re-key
2452 phase. Affected file is silcd/idlist.[ch].
2454 * Implemented the simple re-key protocol into the server.
2455 Affected files silcd/server.c and silcd/protocol.[ch]. The
2456 re-key will be performed once in an hour, by default.
2458 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2459 Added silc_server_rekey, silc_server_rekey_callback and
2460 silc_server_rekey_final.
2462 * Removed Tunneled flag from the protocol. Updated the code
2463 and the specifications.
2465 * Adde `pfs' field to the SilcIDListData to indicate whether
2466 the PFS is to be performed in the re-key. Affected file is
2469 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2471 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2472 int64 of at least the xintXX size. If void * is less that 4
2473 bytes uint32 * will be used. Defined bool as boolean.
2475 * Changed _ALL_ unsigned long and unsigned int to uint32,
2476 unsgined short to uint16 in the source tree.
2478 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2479 not handle clients that has entry->data.registered == FALSE.
2480 They are not in the network anymore. Affected file is
2483 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Implemented the sending of the SERVER_SIGNOFF notify in the
2486 server. Affected file is silcd/server.c.
2488 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2489 Added also silc_notify_payload_encode_args into the
2490 lib/silccore/silcnotify.[ch].
2492 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2493 Affected file silcd/packet_receive.c.
2495 * Implemented the SERVER_SIGNOFF notify handling in the client
2496 library. Affected file lib/silcclient/client_notify.c. Also,
2497 implemnted the printing of the SERVER_SIGNOFF info to the
2498 application. Affected file silc/client_ops.c.
2500 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2501 if the deleting was successful. Affected file silcd/idlist.[ch].
2503 * Added support for public key authentication in the connection
2504 authentication protocol in the client library. Affected file
2505 lib/silcclient/protocol.c.
2507 * Changed the server's silc_idlist_get_clients_by_* interface
2508 to support already allocated array so that new entries may be
2509 added to pre-allocated array. Affected file silcd/idlist.[ch].
2510 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2511 and command replies.
2513 * All command reply functions in the server now calls the
2514 pending command callback even if error occured. This way the
2515 error will be delivered to the client as well. Affected files
2516 silcd/command.c and silcd/command_reply.c.
2518 * Fixed INFO command to return local server's info if no server
2519 was provided. Affected file lib/silcclient/command.c.
2521 * Removed RESTART command for good. Updated the code and the
2524 * Rewrote parts of the task system. It is a bit simpler now.
2525 Removed unsued task priorities. The affected files are
2526 lib/silcutil/silctask.[ch].
2528 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2530 * Moved the USERS printing from the library to the application.
2531 Affected files lib/silcclient/command.c and silc/client_ops.c.
2533 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2537 * Added channel key re-key support. The re-key is perfomed
2538 only by the router and is done once in an hour. Added `rekey'
2539 field to the SilcChannelEntry in the server. Affected files
2540 silcd/server.c and silcd/idlist.h.
2542 * Added silc_task_unregister_by_context into the file
2543 lib/silcutil/silctask.[ch].
2545 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Added SILC_UMODE_GONE mode to indicate when the client is not
2548 present in the SILC network. Added also support to the local
2549 command AWAY that will set this mode. Added support of showing
2550 "xxx is gone" in WHOIS command. The USERS command shows the
2551 gone status as well.
2553 * Fixed setting server and router operator privileges in the
2554 server's UMODE command. Affected file silcd/command.c.
2556 * Merged the SKE KE1 and KE2 payloads into one payload. The
2557 new KE payload is equivalent to the old KE2 payload.
2559 Cleaned up the SKE Start Payload parsing. It now uses the
2560 simple buffer unformatting to do the parsing. A lot faster
2563 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2564 to the SKE that is used to indicate whether both of the SKE
2565 parties should perform authentication. By default only the
2566 responder performs authentication. By setting this flag also
2567 the initiator must do authentication. By default it is unset
2568 since in normal SKE case, client to server connection, only
2569 the responder should do authentication. When doing SKE between
2570 two clients both should perform authentication. Updated the
2571 code and the protocol specs.
2573 * A little fix to IDENTIFY command in the server. Search the
2574 client first by hash not nickname. Affected file is
2577 * Fixed the silc_client_close_connection to support closing
2578 the client to client connections wihtout deleting too much
2579 data. Affected file lib/silcclient/client.c.
2581 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2582 are received if protocol used to be active but is not anymore
2583 the application would crash due to NULL pointer dereference.
2584 Affected files silcd/server.c and lib/silcclient/client.c.
2586 * Added `hash' field to the SilcClientConnection to include
2587 the hash function negotiated in the SKE protocol.
2589 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2590 to set the channel founder authentication data. A client can
2591 claim the founder rights later by providing the authentication
2592 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2593 This way the channel founder can regain the channel founder
2594 privileges even it is left the channel. This works only on
2595 local server and the client must be connected to the same
2596 server to be able to regain the founder rights. Updated the
2597 protocol specs accordingly.
2599 Added support to the CMODE command in the client to set the
2600 founder auth data. Read the README to see how to set it.
2602 Added support to the CUMODE command to claim the founder
2603 rights. Read the README to see how to do it.
2605 Added support for the founder authentication to the Channel
2606 Entry in the server. Affected file silcd/idlist.h.
2608 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2609 server's CMODE command. Affected file silcd/command.c.
2611 * Added the following new functions into lib/silccore/silcauth.[ch]:
2612 silc_auth_get_method and silc_auth_get_data.
2614 * The server now saves the remote hosts public key to the
2615 SilcIDListData pointer. Affected file silcd/protocol.c.
2617 * The normal server now does not remove the channel entry from
2618 the cache if the founder authentication data is set. It used
2619 to remove it if the founder was the last one on the channel on
2620 the server and left the channel. The auth data is saved and
2621 if the channel is re-joined later the old entry is used with
2622 the old auth data. Affected files silcd/command_reply.c and
2625 * Removed the `pkcs' field from the SilcIDListData structure
2626 in the server; it is not used. Affected file silcd/idlist.h.
2628 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Fixed packet processing on slow links. Partial packets were
2631 never re-processed because the incoming data buffer was cleared
2632 by the application. Application must not directly clear the
2633 sock->inbuf, the packet processing routines handle it. Fixed
2634 this in client library and in server.
2636 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Fixed the WHOIS and IDENTIFY send reply function to really
2639 check whether to send list or just one entry. Affected file
2642 * Cleaned up the LEAVE command's channel key distribution. The
2643 affected file silcd/command.c.
2645 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2646 can enforce the channel mode as well. In that case the ID
2647 includes the ID of the server. The code now enforces the
2648 mode change if the router have different mode than the server.
2650 * The notify client operation with CMODE_CHANGE notify can now
2651 return NULL client_entry pointer if the CMODE was not changed
2652 by client. Application must check for this.
2654 * Added <Server ID> argument to INFO command to support server
2655 info fetching by Server ID.
2657 * Added silc_server_announce_get_channel_users to get assembled
2658 packets of channel users of the specified channel. Affected
2659 file silcd/server.[ch].
2661 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2662 was freed underneath the ID Cache.
2664 * Re-announce clients when the server received CHANNEL_CHANGE
2665 notify from the router. Affected file silcd/packet_send.c.
2667 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2670 crashed since it did not handle the fact that there is no cipher
2671 called "3" and didn't check the error condition. Now fixed.
2673 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2674 flag. It can be used to send message requests.
2676 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Implemented the RESTART command in the client.
2680 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2681 notice type messages. Added notice printing to the user
2684 * The channel keys are not re-generated if the channel's mode
2685 is PRIVKEY, ie private key on the channel exists. Affected
2686 files silcd/server.c and silcd/command.c.
2688 * Fixed a little bug in channel message delivery when channel
2689 private keys are set in the server. Affected file is
2690 silcd/packet_send.c.
2692 * Changed the setting on channel->on_channel = TRUE from the
2693 silc_client_save_channel_key to the JOIN command reply. The
2694 key payload is not received if the private channel key is set.
2695 Affected file lib/silcclient/command_reply.c and the
2696 lib/silcclient/client_channel.c.
2698 * When the CMODE_CHANGE notify is sent and the channel private
2699 key mode is removed the channel key must be re-generated in
2700 other cells as well. Added this support for the router in the
2701 silcd/packet_receive.c.
2703 * Added new local command NOTICE to send notice message on
2704 channel. Affected file silc/local_command.[ch].
2706 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Added new local command ME to the client. It is used to send
2709 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2710 some action. Affected file silc/local_command.[ch].
2712 * Changed channel_message and private_message client operations
2713 to deliver the message flags to the application. Added also
2714 the `flags' arguments to the silc_client_send_channel_message
2715 and silc_client_send_private_message functions. Affected file
2718 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Redefined the Private Message Payload to support private message
2721 keys and to support the new private message flags. Updated
2722 the protocol specs. Flags makes it possible to have for example
2723 CTCP style messages.
2725 * Added new type SilcPrivateMessagePayload and defined an API
2726 for it in the lib/silcclient/silcprivate.[ch].
2728 * Tested private message private keys successfully. Tested the
2729 private message key set, unset and list commands with the new
2732 * Redefined the Channel Message Payload to include the channel
2733 message flags (equal with private message flags) to support
2734 for example CTCP style messages.
2736 * Defined some of the message (for channel and private message)
2737 flags. Updated the protocol specs and added the flags to the
2738 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2740 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2742 * Added SilcKeyAgreementStatus type to the key agreement routines
2743 to indicate the current status and error if one occured.
2744 The status types are defined in the lib/silcclient/silcapi.h.
2746 * Added new local command KEY that is used to set and unset private
2747 keys for channels, set and unset private keys for private messages
2748 with remote clients and to send key agreement requests and
2749 negotiate the key agreement protocol with remote client. The
2750 key agreement is supported only to negotiate private message keys,
2751 it currently cannot be used to negotiate private keys for channels,
2752 as it is not convenient for that purpose.
2754 * Fixed a minor pending callback setting bug in the function
2755 silc_client_get_client_by_id_resolve, now the function works.
2756 Affected file lib/silcclient/idlist.c.
2758 * Added function silc_net_get_local_port to get local bound
2759 port by socket. Added to lib/silcutil/silcnet.[ch].
2761 * Added `sockets' and `sockets_count' fields to the SilcClient
2762 object. They hold the sockets of the listenning sockets in
2763 the client. Listenning sockets may be for example the key
2764 agreement server. Affected file lib/silcclient/client.[ch].
2765 Added functions the silc_client_add_socket and the
2766 silc_client_del_socket. They are exported to the application
2769 * Added ~./silc/clientkeys to support other client's public keys.
2771 * Renamed verify_server_key client operation to verify_public_key
2772 and added one argument to indicate the type of the connection
2773 (server, client etc.).
2775 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Added silc_server_connection_auth_request to handle the
2778 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2779 silcd/packet_receive.[ch].
2781 * Added silc_server_send_connection_auth_request into the
2782 silcd/packet_send.c to send the connection auth request packet.
2784 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2787 * Fixed the public key authentication in responder side in the
2788 server. The `auth_data' pointer includes the SilcPublicKey
2789 not the path to the public key. Affected file silcd/protocol.c.
2791 * Implemented the public key authentication in the initiator side
2792 in the server. Affected file silcd/protocol.c.
2794 * Removed the [RedirectClient] config section from the server
2795 configuration. Is not needed and I don't want to implement it.
2797 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Cleaned up the CMODE command in the server. It now works
2800 correctly and supports all the modes defined in the protocol.
2801 Affected file is silcd/command.c.
2803 * Added `hmac_name' field to the SilcChannelEntry in the server
2804 to hold the default HMAC of the channel. It can be set when
2805 creating the channel (with JOIN command). Affected files
2808 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2809 type to indicate the change of the current cipher and hmac
2810 on the channel. Client can safely ignore the <cipher> argument
2811 (if it chooses to do so) since the CHANNEL_KEY packet will
2812 force the channel key change anyway. The <hmac> argument is
2813 important since the client is responsible of setting the new
2814 HMAC and the hmac key into use.
2816 * Fixed the CMODE command in the client library as well.
2818 * Tested CMODE command in router environment successfully.
2820 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Show the version of the remote client (or server) when connecting
2823 to the server. It is logged to the log file. Affected file
2824 is silcd/protocol.c.
2826 * Fixed the KILLED notify handling in the client library. The
2827 client must be removed from all channels when receiving the
2830 Also, do not remove the client entry when giving the KILL
2831 command but when the KILLED notify is received.
2833 * Removed silc_idlist_find_client_by_nickname from the server.
2834 Not needed anymore. Affected files silcd/idlist.[ch].
2836 * Implemented the CHANNEL_CHANGE notify type handling to the
2837 server. Affected file silcd/server.c.
2841 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Added silc_server_send_notify_invite to send the INVITE
2844 notify between routers.
2846 * Implemented the INVITE command correctly to the server.
2848 * Implemented the INVITE notify type handling in the server.
2850 * Implemented the INVITE command to the client library and on the
2853 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Added function silc_server_get_client_resolve to find the
2856 client entry by ID from all ID lists and then resolve it
2857 (using WHOIS) if it cannot be found. Affected file is
2860 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Implemented the BAN command to the client library.
2864 * The JOIN command in the server now checks the invite list
2867 * Changed the silc_command_reply_payload_encode_va and the
2868 silc_command_payload_encode_va to support that if argument is
2869 NULL it ignores and checks the next argument. Affected file
2870 lib/silccore/silccommand.c.
2872 * Added silc_server_send_notify_ban to send the BAN notify
2873 type between routers.
2875 * Chaned the silc_notify_payload_encode to support that if
2876 argument is NULL it ignores and checks the next argument.
2877 Affected file lib/silccore/silcnotify.c.
2879 * Tested ban lists in router environment successfully.
2881 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Implemented BAN command to the server, in silcd/command.[ch].
2885 * Removed the BAN and INVITE_LIST modes from the CMODE command
2888 * Added function silc_string_match to regex match two strings.
2889 Affected files lib/silcutil/silcutil.[ch].
2891 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Redefined parts of the SilcChannelEntry in the server to support
2894 the new ban and invite lists.
2896 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Redefined the INVITE command. The same command can be used to
2899 invite individuals to the channel but also to manage the invite
2900 list of the channel (to add to and remove from the invite list).
2901 Updated the protocol specs.
2903 * Added new command SILC_COMMAND_BAN that can be used to manage
2904 the ban list of the channel. Updated the protocol specs.
2906 * Removed the channel modes: the SILC_CMODE_BAN and the
2907 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2908 in the CMODE command. The equivalent features are now available
2909 using INVITE and BAN commands. Updated the protocol specs.
2911 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2912 in the network about change in the current ban list. The notify
2913 type is not used by the client.
2915 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2916 support the invite lists.
2918 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Added new function silc_string_regexify that converts string
2921 including wildcard characters into regex string that can
2922 be used by the GNU regex library. Added into the file
2923 lib/silcutil/silcutil.[ch].
2925 Added silc_string_regex_combine to combine to regex strings
2926 into one so that they can be used as one regex string by
2927 the GNU regex library. Added into the file
2928 lib/silcutil/silcutil.[ch].
2930 Added silc_string_regex_match to match two strings. It returns
2931 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2933 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2935 * Imported GNU regex to the soruce tree into lib/contrib.
2936 Fixed some compiler warning from the regex.c.
2938 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Fixed MOTD command in the server to work in router environment.
2942 * Fixed the MOTD command in the client library to support
2943 the server argument in the command.
2945 * Added `nickname_len' argument to the silc_idlist_add_client
2946 in the server, as the `nickname' argument may be binary data
2949 * Added silc_idlist_get_channels to return all channels from
2952 * Implemented LIST command to the server. Affected file is
2955 * Implemented the LIST command to the client library and on the
2958 * Added [<user count>] argument to the LIST command reply.
2959 With private channels the user count is not shown.
2961 * Updated TODO and README.
2963 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * The client entry's data.registered must be TRUE even with
2966 global client entry on global client list. The data.registered
2967 is used to check whether the client is anymore in the network,
2968 for example with WHOWAS command so it must be valid.
2970 * Fixed the WHOWAS command in the server. It now actually works
2971 in router environment. Added function into silcd/command_reply.c
2972 silc_server_command_reply_whowas_save.
2974 * Added silc_idlist_purge function to the silcd/idlist.c
2975 to periodically purge the ID Cache.
2977 * Fixed INFO command in the server. It works now in router
2978 environment. Added <server name> argument to the INFO command
2979 reply. Updated the protocol specs.
2981 * Fixed minor bug in silc_idcache_purge to not purge if the
2982 expire value is zero.
2984 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2985 they were buggy because of the WHOWAS information.
2987 * Fixed local command MSG to handle the async resolving of
2988 the remote client properly. It used to fail the first MSG.
2989 Affected file silc/local_command.c.
2991 * Added `data_len' field to SilcIDCache context.
2993 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Update TODO. Todo in commands in the server.
2997 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3000 used by routers as broadcast packet to inform other routers
3001 about the changed user mode.
3003 Implemented the notify handling in the server. Affected file is
3004 silcd/packet_receive.c. Added the function
3005 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3007 * Added new generic Channel Payload and deprecated the New Channel
3008 Payload. The New Channel Payload is now the generic Channel
3011 * Added new argument `mode' to the silc_server_send_new_channel
3012 as it is required in the Channel Payload now.
3014 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3015 and created a new and real SilChannelPayload to represent the
3016 new generic Channel Payload. Implemented the encode/decode
3017 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3019 * Added silc_server_get_client_channel_list to return the list
3020 of channels the client has joined for WHOIS command reply.
3021 Affected file silcd/server.[ch].
3023 * Implemented the channel list sending in the WHOIS command reply
3024 in server and in the client.
3026 Implemented the channel list displaying on the user interface
3027 as well. Affected file silc/client_ops.c.
3029 * Added silc_channel_payload_parse_list to parse list of Channel
3030 Payloads. It returns SilcDList list of SilcChannelPayloads.
3031 Client for example can use this function to parse the list of
3032 channels it receives in the WHOIS command reply. The caller
3033 must free the list by calling silc_channel_payload_list_free.
3034 Affected files lib/silccore/silcchannel.[ch].
3036 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Added one new argument <user mode> to the WHOIS command reply
3039 to return the mode of the user in SILC. Updated the protocol
3042 Implemented it to the server and client.
3044 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Fixed the mode printing on the user interface on joining.
3047 Affected file silc/client_ops.c.
3049 * Implemented the UMODE command and user modes in general to the
3050 client library and to the user interface.
3052 * Implemented the UMODE command to the server.
3054 * The server now sends UNKNOWN_COMMAND error status if client sends
3055 unknown command. Affected file silcd/command.c.
3057 * All server commands now handle the command identifier the right
3058 way when sending the command reply to the client. The client can
3059 use to identify the command replies with the identifier.
3061 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Added silc_server_get_client_route to resolve the route to
3064 the client indicated by the client ID. Affected file is
3067 * Added silc_server_relay_packet as general function to relay
3068 packet to arbitrary destination. This deprecates functions
3069 like _send_private_message_key, _relay_notify etc. Affected
3070 file is silcd/packet_send.[ch].
3072 Removed silc_server_send_key_agreement,
3073 silc_server_send_private_message_key and
3074 silc_server_packet_relay_notify functions from the file
3075 silcd/packet_send.[ch].
3079 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3080 server. Affected file silcd/packet_receive.[ch].
3082 * Implemented the KILL command to the client. Implemented the
3083 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3084 Affected files lib/silcclient/command[_reply].c and
3085 lib/silcclient/client_notify.c. Implemented the KILL notify
3086 printing in the user inteface.
3088 * Fixed a lot silc_parse_nick memory leaks from the client
3089 library in the file lib/silcclient/command.c.
3091 * Changed the silc_server_send_notify_on_channels's `sender'
3092 argument from SilcSocketConnection to SilcClientEntry to
3093 check the sender as entry and not as connection object and not
3094 to send to the client provided as argument. The affected file
3095 is silcd/packet_send.[ch].
3097 * The notify packets that are destined directly to the client used
3098 to not to be processed by the server. Now changed that and the
3099 server processes all notify packets. After relaying the packet
3100 to the client the notify packet is processed in the server.
3102 * The silc_server_free_client_data now checks whether there is
3103 pending outgoing traffic for the client and purges the data to
3104 the network before removing the client entry.
3106 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3109 an client is killed from the SILC Network. Updated the protocol
3112 Added new function silc_server_send_notify_killed to the
3113 silcd/packet_send.[ch].
3115 * Added function silc_server_packet_relay_notify to relay notify
3116 packets that are destined directly to a client. In this case
3117 the server does not process the notify packets but merely relays
3118 it to the client. Affected file silcd/packet_send.[ch].
3120 Added also silc_server_packet_process_relay_notify to check
3121 whereto relay the notify. Affected file is
3122 silcd/packet_receive.[ch].
3124 * Implemented the KILL command to the server.
3128 * Added the backup schema desgined last fall to the protocol
3129 specs for everyone to see. The specification is in the
3130 *-spec-xx.txt draft and the packet type definitions for the
3131 backup routers is in *-pp-xx.txt draft. Thusly, added also
3132 new packet type SILC_PACKET_CELL_ROUTERS.
3134 * A big security problem in the implementation discovered. The
3135 signoff of an client did not cause new channel key generation
3136 which it of course should've done. The channel keys must be
3137 always re-generated when client leaves (or signoffs) the channel.
3138 The silc_server_remove_from_channels funtion now handles
3139 the channel key re-generation.
3141 * Added `sender' argument to the silc_server_send_notify_on_channels
3142 to not to send the client provided as argument. Affected file
3143 silcd/packet_send.[ch].
3145 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Implemented OPER and SILCOPER commands into the server and
3150 * Added silc_auth_verify and silc_auth_verify_data to verify
3151 the authentication directly from the authentication payload.
3152 It supports verifying both passphrase and public key based
3153 authentication. Affected file lib/silccore/silcauth.[ch].
3155 * Added `hash' field to the SilcIDListData structure. It is the
3156 hash negotiated in the SKE protocol. Affected file is
3159 * Slight redesigning of the SilcAuthPayload handling routines.
3160 Do not send SilcPKCS but SilcPublicKey as argument.
3162 * Implemented the public key authentication support to the
3163 serverconfig. The public key is loaded from the provided path
3164 and saved as authentication data to void * pointer. Thus,
3165 changed the unsigned char *auth_data to void *auth_data;
3167 * Fixed SHUTDOWN command to send the reply before the server
3168 is shutdown. :) Affected file silcd/command.c.
3170 * Fixed fatal bug in CONNECT command. The hostname was invalid
3171 memory and server crashed. Affected file silcd/command.c.
3173 * Fixed fatal bug in CLOSE command. The server_entry became
3174 invalid but was referenced later in the command. Affected file
3177 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Fixed fatal bug in failure packet handling. Server ignored
3180 the failure and thus crashed when it came.
3184 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3187 that the command may be executed only once in (about) 2 seconds.
3188 The old SILC_CF_LAG flag is same but allows command bursts up
3189 to five before limiting.
3191 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3192 server code. Various commands now includes the CF_LAG_STRICT
3193 flag to disallow any kind of miss-use of the command.
3195 * Fixed the silc_buffer_unformat to not to allocate any data
3196 if the length of the data is zero. It used to allocate the
3197 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3199 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Changed the format of AdminConnection configuration section
3202 in the server. Added username of the admin to the format.
3203 Affected files silcd/serverconfig.[ch].
3205 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3206 to return admin configuration data by host, username and/or
3209 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Implemented WHOWAS command to the server. Added the functions:
3213 silc_server_command_whowas_parse,
3214 silc_server_command_whowas_send_reply,
3215 silc_server_command_whowas_from_client and
3216 silc_server_command_whowas_from_server
3218 * Added <Client ID> argument to the WHOWAS command reply. Updated
3219 the protocol specs accordingly.
3221 * Implemented WHOWAS command and command_reply to the client
3224 Implemented the WHOWAS printing on the user interface.
3226 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Added new argument to the WHOWAS command reply, the real name.
3229 It is an optional argument. Updated the protocol specs.
3231 * Added SilcIDCacheDestructor callback that is registered when
3232 the SilcIDCache is allocated. The callback is called when
3233 an cache entry in the ID Cache expires, or is purged from the
3234 cache. Added into lib/silccore/idcache.[ch].
3236 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3237 to destruct the client entries when the cache entry expires.
3238 Other ID Cache's in server and in the client library ignores
3241 * If the ID Cache entry's `expire' field is zero then the entry
3242 never expires. Added boolean `expire' argument to the
3243 silc_idcache_add function in the lib/silccore/idcache.[ch].
3244 If it is TRUE the default expiry value is used.
3246 * Added silc_server_free_client_data_timeout that is registered
3247 when client disconnects. By default for 5 minutes we preserve
3248 the client entry for history - for WHOWAS command.
3250 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Added support to the server to enforce that commands are not
3253 executed more than once in 2 seconds. If server receives
3254 commands from client more frequently, timeout is registered
3255 to process the commands. Affected file silcd/command.c.
3256 Added new function silc_server_command_process_timeout.
3258 * Changed NICK_NOTIFY handling in client library to check that
3259 if the client's nickname was changed, so there is no need to
3260 resolve anything from the server.
3262 * Removed error printing from the WHOIS and IDENTIFY commands.
3263 If error occurs then it is ignored silently in the client library.
3264 The application, however, may map the received error to
3265 human readable error string. The application currently maps
3266 the NO_SUCH_NICKNAME error to string.
3268 * Made the command status message public to the application. Moved
3269 them from lib/silcclient/command_reply.c to
3270 lib/silcclient/command_reply.h. The application can map the
3271 received command status to the string with the
3272 silc_client_command_status_message function.
3274 * Added check to the server to check that client's ID is same
3275 as the Source ID in the packet the client sent. They must
3278 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Added dist-bzip hook to the Makefile.am to make bzip2
3281 compressed distributions.
3283 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Server now enforces the maximum length for the nickname and
3286 the channel as protocol specification dictates. 128 bytes for
3287 nickname and 256 bytes for channel name.
3289 * Moved the WHOIS printing to the application. The client libary
3290 does not print out the WHOIS information anymore, the application
3291 must do it. Renamed silc_client_command_reply_whois_print to
3292 the silc_client_command_reply_whois_save.
3294 The client's idle time is also sent to the application now, and
3295 the idle is shown on screen.
3297 * Added silc_client_command_reply_identify_save to save the
3298 received IDENTIFY entries.
3300 * Do not check for channel private keys in message sending and
3301 reception if the channel does not have the PRIVKEY mode set.
3302 Affected file lib/silclient/client_channel.c.
3304 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3307 just surfaced after chaning the JOIN procedure.
3309 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Added silc_client_get_clients_by_list to get client entries
3312 from Client ID list, that is returned for example by JOIN
3313 and USERS command replies. The application should use this
3314 function for example when JOIN command reply is received to
3315 resolve the clients already on the channel (library does not
3316 do that anymore as USERS command reply is not used in the JOIN
3317 procedure anymore). Affected files lib/silcclient/silcapi.h and
3318 lib/silcclient/idlist.c.
3320 * JOIN command reply and USERS command reply returns now SilcBuffer
3321 pointers instead of unsigned char pointers when returning
3322 the client list and mode list.
3324 * Added <Client ID> argument to the JOIN command reply, mainly
3325 for the server to identify for which client the command was
3326 originally sent. Updated protocol specs accordingly.
3328 * Added SilcDlist private_key pointer to the SilcChannelEntry
3329 in the client to support the channel private keys. Affected
3330 file is lib/silcclient/idlist.h.
3332 * Added SilcChannelPrivateKey argument to the function
3333 silc_client_send_channel_message so that application can choose
3334 to use specific private ke if it wants to. If it is not provided,
3335 the normal channel key is used, unless private keys are set.
3336 In this case the first (key that was added first) is used
3337 as the encryption key.
3339 * Implemented the support for channel private key handling.
3340 Implemented the following functions:
3342 silc_client_add_channel_private_key,
3343 silc_client_del_channel_private_keys,
3344 silc_client_del_channel_private_key,
3345 silc_client_list_channel_private_keys and
3346 silc_client_free_channel_private_keys
3348 Affected file lib/silcclient/client_channel.c.
3350 * Added the support for the private keys in the channel message
3351 sending and encryption and in the message reception and
3352 decryption. Affected funtions are
3353 silc_client_send_channel_message and silc_client_channel_message.
3355 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Added SKE's key verify callback to the client library's
3358 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3360 * Removed the statement that server (or router) must send USERS
3361 command reply when joining to the channel so that the client
3362 knows who are on the channel. Instead, the client list and
3363 client's mode list is now sent in the JOIN command reply to the
3364 client who joined channel. This is better solution.
3366 * Added function silc_server_get_users_on_channel and function
3367 silc_server_save_users_on_channel to the silcd/server.[ch].
3369 * Removed function silc_server_command_send_users from the
3372 * Do not show topic on the client library anymore. The topic is
3373 sent in the command reply notify to the application and the
3374 application must show the topic now.
3376 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Added client searching by nickname hash into the IDENTIFY and
3379 WHOIS commands in the server as they were clearly missing from
3380 them. Affected file is silcd/command.c.
3382 * Fixed a bug in private message receiving in the client library.
3383 The remote ID was freed and it wasn't supposed, now it is
3386 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Minor fix to the channel payload; allocate the data area, as it
3389 needs to be of specific length.
3391 * If the key agreement port is zero then the operating
3392 system will define the bound port. Affected files are
3393 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3395 * Added new function silc_channel_payload_decrypt into the file
3396 lib/silccore/silcchannel.[ch].
3398 * Moved the channel message etc, check from silc_packet_decrypt
3399 to applications. The library calls now a generic
3400 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3401 when the packet is either normal or special. This was done to
3402 allow more wide range of checking that was not allowed when
3403 the code was in library. Now applications can do virtually any
3404 checks to the packet and return to the library the decision how
3405 the packet should be processed. Affected files are
3406 lib/silccore/silcpacket.[ch].
3408 Added silc_server_packet_decrypt_check to the server and
3409 silc_client_packet_decrypt_check to the client library.
3411 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3412 to send with specified source and destination information.
3414 * Channel message delivery between routers was broken after the
3415 channel key distribution was fixed earlier. The channel key
3416 was used be to distributed to other routers as well which is not
3417 allowed by the protocol. Now this is fixed and channel keys
3418 really are cell specific and the channel message delivery between
3419 routers comply with the protocol specification.
3421 * Fixed various commands in server to check also the global list
3422 for the channel entry and not just the local list. The affected
3423 file silcd/command.c.
3425 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Added assert()s to buffer formatting and unformatting routines
3428 to assert (if --enable-debug) when error occurs. Affected
3429 file: lib/silcutil/silcbuffmt.c.
3431 * Changed to auto-reconnect to check whether the remote host is
3432 router and register the re-connect timeout if it is. It used
3433 to check that whether we are normal server, but router must do
3434 auto-reconnect with another router as well. Affected file
3437 * Removed the [<key len>] option from CMODE command as the cipher
3438 name decides the key length, nowadays. See the defined ciphers
3439 from the protocol specification.
3441 * Added [<hmac>] option to the CMODE command to define the HMAC
3442 for the channel. Added SILC_CMODE_HMAC channel mode.
3444 * Added [<hmac>] option for the JOIN command so that user can
3445 select which HMAC is used to compute the MACs of the channel
3448 * Added Hmac field to the Channel Message Payload. The integrity
3449 of plaintext channel messages are now protected by computing
3450 MAC of the message and attaching the MAC to the payload. The
3451 MAC is encrypted. Now, it is clear that this causes some
3452 overhead to the size of the packet but rationale for this is that
3453 now the receiver can verify whether the channel message decrypted
3454 correctly and also when private keys are set for the channel the
3455 receiver can decrypt the packet with several keys and check from
3456 the MAC which key decrypted the message correctly.
3458 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3459 lib/silccrypt/silccipher.[ch].
3461 * Added silc_hash_len to return the digest length into the
3462 lib/silcrypt/silchash.[ch].
3464 * Rewrote parts of Silc Channel Payload interface in the
3465 lib/silccore/silcchannel.[ch]. The encode function now also
3466 encrypts the packet and parse function decrypts it.
3468 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Fixed a minor formatting bug in the SKE's key material processing.
3471 It actually might have processed the keys wrong way resulting
3474 * Redefined the mandatory HMAC algorithms and added new algorithms.
3475 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3476 and hmac-md5 truncated to 96 bits. The mandatory is now
3477 hmac-sha1-96. Rest are optional (including the one that used
3478 to be mandatory). Rationale for this is that the truncated HMAC
3479 length is sufficient from security point of view and can actually
3480 make the attack against the HMAC harder. Also, the truncated
3481 HMAC causes less overhead to the packets. See the RFC2104 for
3484 * Added new [hmac] configuration section. The SKE used to use
3485 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3486 is of course wrong. The official names that must be proposed in
3487 the SKE are the ones defined in the protocol specification
3488 (hmac-sha1-96 for example). The user can configure any hmac
3489 using any hash function configured in the [hash] section. At
3490 least, the mandatory must be configured.
3492 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3494 * Added HMAC list to the SKE proposal list. It has now both
3495 hash algorithm list and HMAC list. This makes the protocol
3496 incompatible with previous versions. The SKE now seems to work
3497 the way it is supposed to work, for the first time actually.
3499 * Defined plain Hash algorithms to the protocol specification.
3502 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Implemented support for key agreement packets into the server.
3505 Added functions silc_server_key_agreement and
3506 silc_server_send_key_agreement. Other than these functions,
3507 server has nothing to do with this packet.
3509 * Added support for private message key packets into the server.
3510 Added functions silc_server_private_message_key and
3511 silc_server_send_private_message_key.
3515 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3516 called in the protocol's final callback instead in the END
3517 protocol state. This makes a little more sense and in the same
3518 time in client we can use the same protocol routines for normal
3519 key exchange and to key agreement packet handling as well.
3521 * Added to both client's and server's KE protocol context the
3522 SilcSKEKeyMaterial pointer to save the key material. We will
3523 bring the key material to the protocol's final callback by doing
3524 this. The final callback must free the key material.
3526 * Added SKE's packet_send callback into client's KE protocol
3527 context so that the caller can choose what packet sending function
3528 is used. This way we can use different packet sending when
3529 doing normal SKE when doing key agreement packet handling (in
3530 the key agreement packet handling we do not want to encrypt
3533 * Implemented the responder side of the key agreement routines
3534 in the client. The client can now bind to specified port and
3535 accept incoming key negotiation. The key material is passed
3536 to the application after the protocol is over.
3538 * Implemented the processing of incoming Key Agreement packet
3539 in the client. Added function silc_client_key_agreement to
3542 * Implemented the intiator side of the key agreement routines
3543 in the client. The client can now initiate key agreement with
3544 another remote client. The key material is passed to the
3545 application after the protocol is over.
3547 * Created client_keyagr.c to include all the key agreement
3550 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3551 SILC_TASK_CALLBACK except that it is not static.
3553 * Created client_notify.c and moved the Notify packet handling
3554 from the client.[ch] into that file.
3556 * Created client_prvmsg.c and moved all private message and
3557 private message key routines from the client.[ch] into that file.
3559 * Create client_channel.c and moved all channel message and
3560 channel private key routines from the client.[ch] into that file.
3562 * Changed silc_client_get_client_by_id_resolve to resolve with
3563 WHOIS command instead of IDENTIFY command, in the file
3564 lib/silclient/idlist.c.
3566 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Implemented the SKE's responder side to the Client library.
3570 * When FAILURE is received to the protocol do not trust it
3571 blindly. Register a timeout to wait whether the remote closes
3572 the connection as it should do it, only after that process the
3573 actual failure. This was changed to both client and server.
3575 * Added client_internal.h to include some of the structures
3576 there instead of client.h in lib/silcclient/.
3578 * Added function silc_task_unregister_by_callback to unregister
3579 timeouts by the callback function.
3581 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Some "Incomplete WHOIS info" errors has been appearing on the
3584 log files. Took away the entry->userinfo check from WHOIS
3585 reply sending. The entry->userinfo is now " " if client did not
3586 provide one. I thought this was fixed earlier but something
3587 is wrong still. Let's see if the error still appears.
3589 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Fixed a minor bug in the login when the channel key is
3592 re-generated in the server. It used to generate the key in
3593 wrong order and thus caused problems in the channel traffic.
3595 * Fixed a minor bug in channel key distsribution after
3596 KICK command. The key was not sent to the router even though
3599 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Added silc_ske_process_key_material_data as generic routine
3602 to process any key material as the SILC protocol dictates. The
3603 function is used by the actual SKE library but can be used by
3604 applications as well. This relates to the private message keys
3605 and the channel private keys since they must be processed the
3606 same way the normal SILC session keys. The protocol dictates
3607 this. Affected files: lib/silcske/silcske.[ch].
3609 Added also silc_ske_free_key_material to free the
3610 SilcSKEKeyMaterial structure.
3612 * Defined silc_cipher_set_key function to set the key for
3613 cipher without using the object's method function. The affected
3614 files: lib/silccrypt/silccipher.[ch].
3616 * Implemented silc silc_client_add_private_message_key,
3617 silc_client_add_private_message_key_ske,
3618 silc_client_del_private_message_key,
3619 silc_client_list_private_message_keys and
3620 silc_client_free_private_message_keys functions in the
3623 Added functions silc_client_send_private_message_key to send
3624 the Private Message Key payload and silc_client_private_message_key
3625 to handle incoming Private Message Key payload.
3627 * Added Cipher field to the Private Message Key payload to set
3628 the cipher to be used. If ignored, the default cipher defined
3629 in the SILC protocol (aes-256-cbc) is used.
3631 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Removed lib/silcclient/ops.h file.
3635 Redefined parts of the SILC Client Library API. Created new
3636 file silcapi.h that deprecates the ops.h file and defines the
3637 published Client Library API. Defined also private message key
3638 API and channel private key API into the file.
3640 This is the file that the application must include from the
3641 SILC Client Library. Other files need not be included by
3642 the application anymore.
3644 * Added new key_agreement client operation callback and also
3645 defined the Key Agreement library API for the application.
3647 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3650 is used by clients to request key negotiation between another
3651 client in the SILC network. If the negotiation is started it
3652 is performed using the SKE protocol. The result of the
3653 negotiation, the secret key material, can be used for example
3654 as private message key.
3656 Implemented the Key Agreement payload into the files
3657 lib/silccore/silauth.[ch].
3659 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Redefined ciphers for the SILC protocol. Added some new ciphers
3662 and defined the key lengths for the algorithms. Changed the
3663 code accordingly. The default key length is now 256 bits.
3665 * Fixed SKE key distribution function silc_ske_process_key_material
3666 when the key length is more than 128 bits. The default key
3667 length in SILC is now 256 bits.
3669 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3670 to indicate unsupported algorithm.
3672 * Renamed rijndael.c to aes.c and all functions as well.
3674 * Fixed a long standing channel key setting bug in client library.
3675 Weird that it has never surfaced before.
3677 * Fixed bug in channel deletion. If the entire channel is removed
3678 then it must also delete the references of the channel entry
3679 from the client's channel list as the client's channel entry and
3680 the channel's client entry share same memory.
3682 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Implemented CONNECT and SHUTDOWN commands in the client.
3686 * Implemented CLOSE command to the client.
3688 * Added the function silc_idlist_find_server_by_name into the
3689 files silcd/idlist.[ch].
3691 Added the function silc_idlist_find_server_by_conn into the
3692 files silcd/idlist.[ch].
3694 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * DIE command was renamed to SHUTDOWN. Updated the both code
3699 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3700 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3702 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3705 * Added function silc_server_create_connection function to create
3706 connection to remote router. My server implementation actually
3707 does not allow router to connect to normal server (it expects
3708 that normal server always initiates the connection to the router)
3709 so the CONNECT command is only good for connecting to another
3712 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3715 or some other client was kicked from the channel.
3717 Implemented the handling of the notify type to both client
3720 Implemented silc_server_send_notify_kicked to send the KICKED
3721 notify. It is used to send it to the server's primary router.
3723 * Implemented the KICK command into server and client.
3725 * Added `query' argument to the silc_idlist_get_client function
3726 to indicate whether to query the client from server or not if
3729 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3730 to indicate that the client is not channel founder.
3734 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Removed the rng context from SilcPacketContext structure and
3737 changed that the packet routine uses the Global RNG API.
3739 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Added support for quit message that client can "leave" on the
3742 channel when it quits the SILC. It is ditributed inside the
3743 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3745 Added silc_server_free_client_data that will take the
3746 signoff message as argument.
3748 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3750 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Updated parts of the protocol specification to keep it up
3755 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3758 payloads in one packet.
3760 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3761 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3762 use now the new List flag.
3764 * Also deprecated the following packet types: REPLACE_ID,
3765 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3767 * Added list support for Notify packet in server.
3769 * Added silc_server_send_notify_channel_change to send the
3770 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3771 the silc_server_send_replace_id.
3773 * Added silc_server_send_notify_nick_change to send the
3774 NICK_CHANGE notify type. Deprecates the function
3775 silc_server_send_replace_id.
3777 * Added silc_server_send_notify_join to send the JOIN notify type.
3778 Deprecates the function silc_server_send_new_channel_user.
3780 * Added silc_server_send_notify_leave to send LEAVE notify type.
3781 Deprecates the function silc_server_send_remove_channel_user.
3783 * Added silc_server_send_notify_cmode and
3784 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3785 types. Deprecates the silc_server_send_set_mode function.
3787 * Added SERVER_SIGNOFF notify type to indicate that server has
3788 quit. This means that all clients on the channel from that
3789 server will drop. This can be also used when netsplit happens.
3791 Deprecated REMOVE_ID packet type since it is not needed anymore
3794 Added silc_server_send_notify_server_signoff to send the
3795 SERVER_SIGNOFF notify type. Deprecates the function
3796 silc_server_send_remove_id.
3798 Added also silc_server_send_notify_signoff to send the
3799 SIGNOFF notify type.
3801 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3802 SILC protocol from this day on. Changed the protocol
3803 specification as well.
3805 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3806 notify type. It is used between routers to notify about
3807 topic changes on a channel.
3809 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3812 * Partly updated the protocol specification to comply with the
3813 changes now made. It is still though a bit outdated.
3815 * The JOIN notify type now takes one extra argument <Channel ID>.
3816 The packet used to be destined to the channel but now the
3817 JOIN type may be sent as list thus it is impossible to
3818 destine it to any specific channel. By adding this argument
3819 it is again possible.
3821 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Added CREDITS file. The CHANGES and CREDITS file will appear
3824 in the distribution as well.
3826 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3829 types in the server's silcd/packet_receive.c.
3831 * Implemented CMODE and CUMODE to work in router environment.
3833 * Fixed minor encoding and decoding buglet from the
3834 lib/silccore/silcmode.c.
3836 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3839 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3841 * Changed all SilcConfigServer* and silc_config_server* to
3842 SilcServerConfig* and silc_server_config*, respectively.
3845 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Associated the ID (client or server ID) to the Authentication
3848 Payload to avoid any possibility of forging. Updated the
3849 protocol specification and the code accordingly.
3851 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3853 * The RSA key length is now save to the RsaKey context in the
3854 key generation process in lib/silccrypt/rsa.c. The key length
3855 is now used to figure out the maximum size of the block allowed
3856 to be encrypted/signed.
3858 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3859 is equivalent to the silc_mp_mp2bin but does not allocate any
3862 * Changed silc_mp_mp2bin API to take length argument. If it is
3863 non-zero then the buffer is allocated that large. If zero, then
3864 the size is approximated using silc_mp_sizeinbase, which however
3867 * Created Global RNG API which is global RNG that application can
3868 initialize. After initializing, any routine anywhere in the
3869 code (including library) can use RNG without allocating a new
3870 RNG object. This was done to allow this sort of use of the
3871 RNG in code that has no chance to allocate RNG object. All
3872 applications currently allocate this and many routines in the
3873 library use this. Affected file lib/silccrypt/silcrng.[ch].
3875 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3876 it to use the Global RNG API.
3878 * Defined Authentication Payload into protocol specification that
3879 is used during SILC session to authenticate entities. It is
3880 used for example by client to authenticate itself to the server
3881 to obtain server operator privileges.
3883 Implemented this payload into the lib/silccore/silcauth.[ch].
3884 Implemented also routines for public key based authentication
3885 as the new protocol specification dictates.
3887 Moved definitions of different authentication methods from
3888 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3890 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3891 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3892 silc_pkcs_verify_with_hash functions into the file
3893 lib/silccrypt/silcpkcs.[ch].
3895 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * The client entry's userinfo pointer must be always valid.
3898 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3899 will fail since it requires the userinfo. Now, the userinfo
3900 is allocated as "" if actual userinfo does not exist. Actually,
3901 it must exist and it is totally Ok to drop client connections
3902 that does not announce the userinfo. However, we will make
3903 this workaround for now.
3905 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3906 to return the remote port by socket.
3908 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3911 SILC_SERVER_PENDING_EXEC and added an new macro
3912 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3913 data or when error occurs while processing the pending command.
3915 Added new argument `destructor' into silc_server_command_pending
3916 and to the SilcServerCommandPending object. This destructor is
3917 now called after calling the pending callback or if error occurs
3918 immediately. If error occurs the actual pending callback won't
3919 be called at all - only the destructor. The destructor may be
3920 NULL if destructor is not needed.
3922 All this applies for client library code as well. Similar
3923 changes were made there as well for the pending commands.
3925 In the client, the application must now allocate the
3926 SilcClientCommandContext with the silc_client_command_alloc
3929 * Added reference counter to the SilcServerCommandContext. Added
3930 function silc_server_command_alloc and silc_server_command_dup
3933 Same type of functions added to the client library for the same
3936 * Removed the cmd_ident from IDListData away since it is now
3937 global for all connections. It is the command identifier used
3938 in command sending and with pending commands. The affected file
3941 * Added reference counter to the SilcSocketConnection objecet to
3942 indicate the usage count of the object. The object won't be
3943 freed untill the reference counter hits zero. Currently only
3944 server uses this, and client ignores it. The client must be
3945 set to use this too later. The affected files are
3946 lib/silccore/silcsockconn.[ch]. Added also the function
3947 silc_socket_dup to increase the reference counter.
3949 This was mainly added because it is possible that the socket
3950 is removed underneath of pending command or other async
3951 operation. Now it won't be free'd and proper DISCONNECTING
3952 flags, etc. can be set to avoid sending data to connection that
3953 is not valid anymore.
3955 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3956 the connection. After that it sets SILC_SET_DISCONNECTED.
3957 It is, however, possible that the socket data is not still freed.
3958 The silc_server_packet_process now checks that data is not
3959 read or written to connection that is DISCONNECTED. The socket
3960 get's freed when the reference counter hits zero.
3962 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Changed the client operation API: channel_message operation's
3965 `sender' is now the client entry of the sender, not the nickname
3966 and the `channel' is the channel entry, not the channel name.
3968 In the private_message operation the `sender' is now also the
3969 client entry of the sender not the nickname.
3971 Affected file is lib/silcclient/ops.h and all applications
3972 using the client operations.
3974 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Moved the calling of ops->connect() from connect_to_server_final
3977 into receive_new_id functin since that is the point when the
3978 client is actually allowed to send traffic to network. The
3979 affected file is lib/silcclient/client.c.
3981 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3984 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3985 (if needs broadcasting) instead of broadcasting the packets one
3986 by one which would make a burst in the network traffic.
3988 * Added `broadcast' argument to the functions in silcd/server.[ch]
3989 silc_server_create_new_channel[_with_id] to indicate whether
3990 to send New Channel packet to primary router.
3992 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Added new function into the silcd/server.[ch] files:
3995 silc_server_create_new_channel_with_id to create new channel with
3996 already existing Channel ID.
3998 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3999 lib/silccore/silcpacket.h. This packet is used t send list of
4000 Set Mode payloads inside one packet. Server uses this to set
4001 the modes for the channels and clients on those channels, that it
4002 announced to the router when it connected to it. The protocol
4003 specification has been updated accordingly.
4005 * The silc_server_new_channel did not handle the packet coming
4006 from normal server as it normally does not send that. However,
4007 when it announces its channels it does send it. Implemented
4008 the support for that.
4010 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4011 into the file lib/silccore/id.h.
4013 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Fixed memory leaks in the functions silc_idlist_del_client,
4016 silc_idlist_del_channel and silc_idlist_del_server in the file
4017 silcd/idlist.c. All of those leaked like a sieve.
4019 * Fixed some small memory leaks in the client's function
4020 silc_client_notify_by_server.
4022 * Added functions into silcd/server.c: silc_server_announce_clients,
4023 silc_server_announce_channels and silc_server_announce_server.
4024 These functions are used by normal and router server to announce
4025 to its primary router about clients, channels and servers (when
4026 router) that we own. This is done after we've connected to the
4029 These functions effectively implements the following packet types:
4030 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4031 and SILC_PACKET_NEW_ID_LIST.
4033 * Added new functions into the silcd/packet_receive.[ch]:
4034 silc_server_new_id_list, silc_server_new_channel_list and
4035 silc_server_new_channel_user_list to handle the incoming
4036 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4038 * Added support of changing Channel ID in the function
4039 silc_server_replace_id. If the server that announces a channel
4040 to the router already exists in the router (with same name but
4041 with different Channel ID), router is responsible to send
4042 Replace ID packet to the server and force the server to change
4043 the Channel ID to the one router has.
4045 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4046 client that the Channel ID has been changed by the router. The
4047 normal server sends this to the client. Client must start using
4048 the new Channel ID as the channel's ID.
4050 Implemented handling of this new type into lib/silcclient/client.c
4051 into the function silc_client_notify_by_server.
4053 * Added new function silc_idlist_replace_channel_id into the files
4054 silcd/idlist.[ch] to replace the Channel ID.
4056 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Call silc_server_command_identify_check always when processing
4059 the IDENTIFY command in silcd/command.c
4061 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4064 send keepalive packets. The packet can be sent by clients,
4065 servers and routers.
4067 Added function silc_socket_set_heartbeat into the file
4068 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4069 If not set, the heartbeat is not performed. The actual
4070 heartbeat is implemented in the low level socket connection
4071 library. However, application is responsible of actually
4074 Added silc_server_send_heartbeat to send the actual heartbeat
4075 packet into silcd/packet_send.[ch]. Server now performs
4076 keepalive with all connections.
4078 * Added silc_task_get_first function into lib/silcutil/silctask.c
4079 to return the timeout task with shortest timeout. There was a bug
4080 in task unregistration that caused problems. TODO has been
4081 updated to include that task system must be rewritten.
4083 * The client library will now resolve the client information when
4084 receiving JOIN notify from server for client that we know but
4085 have incomplete information.
4087 * Rewrote parts of silc_server_remove_from_channels and
4088 silc_server_remove_from_one_channel as they did not remove the
4089 channel in some circumstances even though they should've.
4091 * Encryption problem encountered in server:
4093 The LEAVE command used to send the Channel Key packet to the
4094 router immediately after generating it. However, the code
4095 had earlier sent Remove Channel user packet but not immediately,
4096 ie. it was put to queue. The order of packets in the router
4097 was that Channel Key packet was first and Remove Channel User
4098 packet was second, even though they were encrypted in the
4099 reverse order. For this reason, MAC check failed. Now, this
4100 is fixed by not sending the Channel Key packet immediately but
4101 putting it to queue. However, this is more fundamental problem:
4102 packets that are in queue should actually not be encrypted
4103 because packets that are sent immediately gets encrypted
4104 actually with wrong IV (and thus MAC check fails). So, packets
4105 that are in queue should be encrypted when they are sent to
4106 the wire and not when they put to the queue.
4108 However, the problem is that the current system has not been
4109 designed to work that way. Instead, the packet is encrypted
4110 as soon as possible and left to the queue. The queue is then
4111 just purged into wire. There won't be any fixes for this
4112 any time soon. So, the current semantic for packet sending
4115 o If you send packet to remote host and do not force the send
4116 (the packet will be in queue) then all subsequent packets to the
4117 same remote host must also be put to the queue. Only after the
4118 queue has been purged is it safe again to force the packet
4121 o If you send all packets immediately then it safe to send
4122 any of subsequent packets through the queue, however, after
4123 the first packet is put to queue then any subsequent packets
4124 must also be put to the queue.
4126 Follow these rules and everything works fine.
4128 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added new function silc_server_remove_clients_by_server to
4131 remove all client entries from ID list when the server connection
4132 is lost. In this case it is also important to invalidate all
4133 client entires as they hold the invalid server entry. This
4134 fixes fatal bug when server has lost connection and will reconnect
4137 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Made some sanity checks to silc_server_daemonise like to check
4140 whether the requested user and group actually exists.
4142 * Added sanity check to SKE's silc_ske_responder_finish to check
4143 that the public and private key actually is valid.
4145 * Invalidate the client's nickname when receiving Replace ID
4146 packet and the Client ID is being replaced. This means that the
4147 server will query the nickname if someone needs it (client)
4150 * Sort the ID Cache in client library when the ID Cache data
4151 has changed (needs sorting).
4153 * Do not allow for SILC client to create several connections to
4154 several servers. The client does not support windows right now
4155 and generating multiple connections causes weird behaviour.
4157 Irssi-silc client does support windows and can handle several
4158 connections without problems, see: www.irssi.org and SILC plugin.
4160 * Fixed some places where client was added to the IDList. The
4161 rule of thumb is following (in order to get everything right):
4162 If the client is directly connected local client then the
4163 `connection' argument must be set and `router' argument must be
4164 NULL to silc_idlist_add_client function. If the client is not
4165 directly connected client then the `router' argument must
4166 bet set and the `connection' argument must be NULL to the
4167 silc_idlist_add_client function.
4169 * The funtion silc_server_packet_send_local_channel actually did
4170 not check whether the client was locally connected or not. It
4171 does that now. Fixed a bug related to LEAVE command.
4173 * Fixed Remove Channel User payload parsing bug in server's
4174 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4176 * The server's silc_server_save_channel_key now checks also the
4177 global ID list for the channel as it might not be in the local
4178 list. Fixed a bug related to LEAVE command.
4180 * Is this the end of the [<unknown>] buglet that has been lurking
4181 around for a long time? A little for loop fix in server's
4182 silc_server_command_whois_parse that is used by both IDENTIFY
4183 and WHOIS command. At least, this was a clear bug and a cause
4184 of one type of [<unknown>] buglet.
4186 * WHOIS and IDENTIFY commands call the function
4187 silc_server_command_[whois/identify]_check function even if
4188 we are not router server.
4190 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Added --with-gmp configuration option. If set the GMP
4193 is always compiled in the SILC source tree. If not set then
4194 it is checked whether the system has the GMP3 installed. If
4195 it has then the GMP won't be compiled (the system's headers
4196 and library is used), if it doesn't have it then the GMP is
4197 compiled in the SILC source tree.
4199 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Changed RSA private exponent generation to what PKCS #1
4202 suggests. We try to find the smallest possible d by doing
4203 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4204 not security fix but optimization.
4206 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Added new config entry [Identity] to fork the server and run
4209 it as specific user and group. A patch from Bostik.
4211 * Imported Dotconf configuration library into lib/dotconf.
4212 This will be used to create the SILC configuration files later.
4213 It will appear in the distsribution after this commit.
4215 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * A big code auditing weekend happening. Auditing code for
4218 obvious mistakes, bugs and errors. Also, removing any code
4221 Removed files for being obsolete:
4223 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4224 inline in the file lib/silcutil/silcbuffer.h)
4226 o lib/silcutil/silcbufutil.c (the header has inline versions)
4228 Changed code to fix possible error conditions:
4230 o The buffer formatting routines now check that the destination
4231 buffer really has enough space to add the data. This applies for
4232 both buffer formatting and unformatting
4233 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4234 unformatting was changed to accomodate following rules:
4235 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4236 sent to the function while XXX_*STRING will not allocate or copy
4237 the data into the buffer. Instead it sets the pointer from the
4238 buffer into the pointer sent as argument (XXX_*STRING used to
4239 require that the pointer must be allocated already). This change
4240 makes this whole thing a bit more consistent and more optimized
4241 (note that the data returned in the unformatting with XXX_*STRING
4242 must not be freed now). The routines return now -1 on error.
4244 o Tried to find all code that use buffer_format and buffer_unformat
4245 and added return value checking to prevent formatting and
4246 especially unformatting errors and possible subsequent fatal
4249 o Changed ske->x and ske->KEY to mallocated pointers in
4250 lib/silcske/silcske.h. Fixed possible data and memory leak.
4252 o Added return value checking to all *_parse* functions. Fixed
4253 many memory leaks as well.
4255 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4256 so that buffer overflows would not happen. All code now also
4257 checks the return value as it can fail.
4259 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Added reconnection support to server if the normal server looses
4262 its connection to the router (for example if router is rebooted).
4263 The server performs normal reconnection strategy implemented
4264 to the server. Affected file silcd/server.c.
4266 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Added new packet type SILC_PACKET_SET_MODE that is used to
4269 distribute the information about changed modes (for clients,
4270 channels and clients channel modes) to all routers in the
4271 network. Updated the protocol specification accordingly.
4273 Added functions into silcd/packet_send.c and
4274 silcd/packet_receive.c: silc_server_send_set_mode,
4275 silc_server_set_mode.
4277 Added new files silcmode.[ch] into lib/silccore that implements
4278 the encoding and decoding of Set Mode Payload. Added new type
4279 SilcSetModePayload. Moved the definitions of different modes
4280 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4282 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Oops, a little mistake in server's connection authentication
4285 protocol. The protocol is not ended with FAILURE but with
4286 SUCCESS if the authentication is Ok. :) Affected file is
4289 * Implemented NICK_CHANGE notify handling in server in the file
4290 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4291 the local clients on the channel. After the changing nickname
4292 in router environment snhould work and the [<unknown>] nickname
4293 should appear no more.
4295 The silc_server_replace_id function that receives the Replace ID
4296 payload now sends the NICK_CHANGE notify type also in the file
4297 silcd/packet_receive.c
4299 * Changed WHOIS and IDENTIFY command to support the maximum amount
4300 of arguments defined in protocol specs (3328 arguments). This
4301 fixed a bug that caused problems when there were more than three
4304 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added extra parameter, command identifier, to the
4307 silc_client_send_command so that explicit command identifier
4310 Changed that ID list routines uses specific command identifier
4311 when sending WHOIS/IDENTIFY requests to the server so that they
4312 can be identified when the reply comes back.
4314 Affected files lib/silcclient/command.[ch],
4315 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4317 * Added `sender' argument to silc_server_packet_send_to_channel
4318 to indicaet the sender who originally sent the packet to us
4319 that we are now re-sending. Ignored if NULL. Affected file
4320 silcd/packet_send.[ch].
4322 * Added some server statistics support in silcd/server_internal.h
4323 SilcServerStatistics structure and around the server code. Also
4324 send some nice statistics information when client is connecting
4327 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Fixed channel ID decoding in server's JOIN command reply in
4330 silcd/command_reply.c
4332 * Fixed braodcasting of replace ID payload to not to send it if
4333 we are standalone server in silcd/packet_receive.c.
4335 * Fixed all channel message sending routines to not to send
4336 packets to clients that has router set, since they are routed
4337 separately in the same function earlier. Affects file
4338 silcd/packet_send.c and all channel packet sending functions.
4340 * In USERS reply, res_argv[i] are not allocated, the table
4341 is allocated. Thus changed that free the table, not its
4344 * In server's whois_check and identify_check if the client is
4345 locally connected do not send any WHOIS commands - they are not
4348 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Fixed some minor bugs in client when sending WHOIS command. The
4351 arguments was in wrong order.
4353 * Removed statis function add_to_channel from server in
4354 silcd/command.c that was previously used with the joining but
4357 * Tested USERS command in router environment successfully with two
4358 routers, two servers and two clients.
4360 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Reorganized the USERS command and command reply in client library
4363 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4364 When the command is given by user we register a pending command
4365 callback that will reprocess the command after the reply has been
4366 received from the server. When reprocessing the packet we then
4367 display the information. Thus, the USERS information is displayed
4368 now in the command callback instead of in the command reply
4369 callback. The processing of the command is same as previously
4370 when server has sent the command reply in the JOINing process.
4372 * Added to USERS command in silcd/command_reply.c to join the client,
4373 we didn't use to know about, to the channel after we've created
4374 a client entry for it. Also, for clienet we did know already still
4375 check whether it is on the channel or not and add it if not.
4377 * Removed silc_server_command_join_notify as the function and its
4380 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Changed the client's pending command handling to the same as the
4383 server's pending command handling. It is also now possible to
4384 execute command reply functions from other command reply
4385 function as the function callbacks for commands and command
4386 replies are one and same. The pending commands are not static
4387 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4388 in client connection context. Thus, pending commands are server
4389 connection specific as it is convenient.
4391 Changed the function silc_client_command_pending and
4392 silc_client_command_pending_del and added new function
4393 silc_client_command_pending_check. Removed the
4394 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4397 * Added cmd_ident, current command identifier, to the client
4398 connection context in lib/silcclient/client.h to keep track on
4399 command identifiers used in command sending. Client's command reply
4400 function handling now supports the mandatory command identifiers.
4402 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4403 funtions in client to fully support pending command callbacks.
4405 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4406 as one of the arguments to the application in the command reply
4409 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4410 before first releasing SILC but came back. Now it is removed again
4411 and should come back nomore. The FORWARDED flag was used only
4412 by the JOINing procedure by forwarding the command packet to router.
4413 Now, the JOINing procedure has been changed to more generic (due
4414 to various router environment issues) and FORWARDED is not needed
4415 anymore for anything. The protocol specification is yet to be
4418 Now, removed silc_server_packet_forward from server and the flag
4419 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4421 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Renamed NAMES command to USERS command. The NAMES was named that
4424 due to historical reasons. Now it is renamed. Also, rewrote
4425 parts of the USERS command. The nickname list is not sent anymore
4426 by the server. Only Client ID and mode lists are sent in the USERS
4427 command. Changed this also to the protocol specification.
4429 The client now resolves the names and stuff after it receives
4430 the USERS list from the server when joining to the channel.
4432 * WHOIS and IDENTIFY commands has been changed to support multiple
4433 Client ID's per command. One can now search for multiple users
4434 in the network by sending only one WHOIS or IDENTIFY command.
4435 Changed the code and the protocol specifications.
4437 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4438 uses silc_server_command_whois_parse to parse the request. */
4440 * If normal server, do not parse the WHOIS and IDENTIFY requests
4441 before sending it to the router. Saves some time.
4443 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Fixed JOIN command on client library. Wrong number of arguments
4446 used to crash the client.
4448 * Added silc_server_channel_has_global function to check whether
4449 channel has global users or not.
4451 * Added silc_server_channel_has_local function to check whether channel
4452 has locally connected clients on the channel.
4454 * The silc_server_remove_from_one_channel now checks whether the
4455 channel has global users or not after given client was removed from
4456 the channel. It also checks whether the channel has local clients
4457 on the channel anymore. If it does not have then the channel entry
4458 is removed as it is not needed anymore.
4460 * The silc_server_notify now checks on JOIN notify whether the joining
4461 client is one of locally connected or global. If it is global then
4462 the channel has now global users on the channel and that is marked
4463 to the channel entry. Also, it now saves the global client to
4464 global list who is joining and JOINs it to the channel. This is
4465 for normal server, that is.
4467 Changed silc_server_send_notify_on_channel,
4468 silc_server_packet_relay_to_channel and
4469 silc_server_packet_send_to_channel check if we are normal server
4470 and client has router set (ie. global client) do not send the
4471 message to that client, as it is already routed to our router.
4473 * Implemented LEAVE notify type handling in silc_server_notify
4476 * Tested LEAVE command in router environment successfully. Tested
4477 with two routers, two servers and two clients.
4481 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4483 * Implemented SIGNOFF notify type handling in silc_server_notify
4486 * silc_server_remove_id now removes the client entry from all channels
4487 it has joined and thusly sends SIGNOFF notify type.
4489 * Rewrote the NAMES list generation in server by removing two excess
4490 loops. The lists are created now inside one loop.
4492 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * silc_server_remove_channel_user checks now also global list
4495 for channel and client.
4497 * silc_server_new_channel_user checks now both local and global
4498 list for channel and client. Fixed a bug in client id decoding.
4499 Used to decode wrong buffer.
4501 * silc_server_channel_message checks now both local and global
4502 list for channel entry.
4504 * Tested channel joining (hence JOIN) in router environment
4505 successfully. Tested with two routers, two servers and two
4508 * Tested channel message sending in router environment successfully.
4510 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Added silc_server_save_channel_key into server.[ch] to save the
4513 received channel key in Channel Key payload processing. It is
4514 also used in JOIN command reply handling.
4516 Equivalent function silc_client_save_channel_key added into
4517 client.[ch] into client library.
4519 * Changed JOIN command reply to send information whether the channel
4520 was created or not (is existing already) and the channel key
4521 payload. Changed protocol specs accordingly.
4523 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4524 the request was sent by ID and not by nickname. Crashed on
4527 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4530 now correctly save the received data.
4532 * silc_server_free_sock_user_data now notifies routers in the
4533 network about entities leaving the network.
4535 At the same time implemented functions silc_server_remove_id
4536 and silc_server_send_remove_id to receive and send REMOVE_ID
4537 packets. The packet is used to notify routers in the network
4538 about leaving entities. The ID removed will become invalid in
4541 * Added function silc_idlist_del_server into server. Removes and
4542 free's server entry from ID list.
4544 * silc_server_private_message function now checks, if we are router,
4545 that the destination ID really is valid ID, naturally.
4547 * In router when NEW_ID packet is received (for new client) the
4548 hash of the Client ID is saved in the ID Cache but the
4549 client->nickname is set to NULL, instead of putting the hash
4552 IDENTIFY command now also checks that client->nickname must be
4553 valid. If it is not if will request the data from the server who
4554 owns the client. Added new function
4555 silc_server_command_identify_check.
4557 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4558 to set the command to already allocated Command Payload.
4560 * Tested private message sending in router environment with two
4561 routers, two servers and two clients. Fixed minor bugs and now
4564 * Fixed segfault from client's NAMES command. Used to crash if
4567 * Forwarded packets must not be routed even if it is not destined
4568 to the receiver. Changed server code comply with this.
4570 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Added `require_reverse_mapping' boolean value to ServerParams
4573 structure. If TRUE (not default) the server will require that
4574 the connecting host has fully qualified domain name.
4576 If the reverse mapping is not required and hostname could not be
4577 found the IP address is used as hostname.
4579 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Implemented version string checking to both client and server.
4582 The check is incomplete currently due to the abnormal version
4583 strings used in development version of SILC.
4585 * Changed all command functions in server to use the new
4588 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Changed char *data to unsigned char *data in ID Cache system to
4591 support binary data as ID Cache data. Changed code to support
4592 binary data in lib/silccore/idcache.c.
4594 * Renamed silc_server_packet_relay_command_reply to
4595 silc_server_command_reply as it is normal packet receiving
4596 function. Rewrote the function to accept command replys for
4597 servers and not only for clients.
4599 * Mark remote router always as registered server if we are connecting
4600 to it. Otherwise, commands sent by the router to us are ignored.
4602 * All ID List find routines now returns the ID Cache Entry pointer
4603 as well if requested.
4605 * WHOIS command works now in router environment, tested with two
4606 routers, two servers and two clients.
4608 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4609 in router environment (as it is almost equivalent to WHOIS) but
4610 hasn't been tested thoroughly. Added new functions:
4612 silc_server_command_identify_parse
4613 silc_server_command_identify_send_reply
4614 silc_server_command_identify_from_client
4615 silc_server_command_identify_from_server
4617 * Disabled route cache adding because adding two different ID's with
4618 same IP replaces the old cache entry thus giving wrong route.
4619 The entry->router->connection is always the fastest route anyway
4620 so route cache may not be needed. Of course, new routes maybe
4621 established after receiving the ID when the entry->router->connection
4622 might not be anymore the most optimal.
4624 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Add route cache for received ID for fast routing.
4628 * Added silc_server_packet_route to route received packet on router
4629 that is not destined to us.
4631 * Renamed silc_server_get_route to silc_server_route_get.
4633 * Added id_string and id_string_len fields into SilcServer to
4634 include encoded ServerID for fast comparing without excess
4635 encoding of the ID's.
4637 * Cleaned up WHOIS command on server side. Added following static
4640 silc_server_command_whois_parse
4641 silc_server_command_whois_check
4642 silc_server_command_whois_send_reply
4643 silc_server_command_whois_from_client
4644 silc_server_command_whois_from_server
4646 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4647 arguments in command replies. All command functions should be
4648 updated to use this macro.
4650 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Minor typo fixes on command reply handling on server.
4654 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Added silc_server_command_add_to_channel internal routine to add
4657 the client to the channel after router has created the channel and
4658 sent command reply to the server.
4660 * Added generic silc_server_send_command to send any command from
4663 * Use static buffer with ID rendering instead of duplicating data.
4665 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Fixed a channel user mode bug when joining to a channel server gave
4668 everybody channel founder rights, oops.
4670 * We mark ourselves as the router of the incoming server connection
4671 if we are router ourselves. This way we can check in some packet
4672 sending functions whether it is locally connected server. For
4673 incoming router connections we put NULL.
4675 * For router sending packets locally means now always sending the
4676 packet cell wide; to local clients and local servers. For normal
4677 server sending packet locally means sending it to only local
4680 * Fixed the JOIN command to really work in router environment. If the
4681 channel is created it is always created by the router. Router is
4682 also responsible of making the initial joining to the channel,
4683 sending JOIN notify to the sending server and distributing
4684 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4685 does not exist server doesn't do anything else but forward the
4686 command to the router which performs everything.
4688 * Added silc_server_send_channel_key function to send the Channel Key
4691 * Added silc_server_create_channel_key to create new channel key. The
4692 channel key is now re-generated everytime someone joins or leaves
4693 a channel, as protocol dictates. Note: channel->key_len is the
4696 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4699 packet_receive.[ch] to separate packet sending and receiving
4700 routines. The server.[ch] now includes everything else including
4701 actual packet processing (writing and reading data) and other
4704 Renamed silc_server_private_message_send_internal to
4705 silc_server_send_private_message. The routine is still though
4706 used only to relay private messages as server does not send
4707 private messages itself.
4709 Renamed silc_server_new_channel to silc_server_create_new_channel
4710 and added new function sicl_server_new_channel that handles the
4711 incoming New Channel packet. Added also new sending function
4712 silc_server_send_new_channel to send New Channel Payload.
4714 * Added new function silc_server_notify to process incoming notify
4715 packet to the server/router. Server may then relay the notify
4716 to clients if needed.
4718 * Added new function silc_server_new_channel_user to process incoming
4719 New Channel User packet. Router will redistribute the packet and
4720 send JOIN notify to its local clients and locally connected servers
4721 if needed. Normal server will send JOIN notify to its local client
4722 on same channel when received this packet. Added also corresponding
4723 sending function silc_server_send_new_channel_user to sent the
4726 * Added boolean route argument to send_notif_to_channel and
4727 packet_send_to_channel functions to attempt to route the packet
4728 if it is TRUE and send only locally if it is FALSE.
4730 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * silc_server_replace_id now broadcasts the received replace ID
4733 packet if it is not broadcast packet already. The router must
4734 broadcast to inform other routers about changed ID.
4736 * Added backpointer to server's router into SilcServer context in
4737 silcd/server_internal.h.
4739 * Fixed silc_server_packet_broadcast to send correct broadcast
4742 * The channel key is now distributed to the local client as soon
4743 as it is received from the router (in router environment) so that
4744 no other packet may be sent for the channel until client has
4747 * silc_server_remove_channel_user now broadcasts the received
4748 Remove Channel User packet if it is not broadcast packet already.
4749 The router must broadcast to inform other routers about removed
4752 * Added users field into SilcPacketContext that is a reference count
4753 of the context. One can increase the reference count by calling
4754 silc_packet_context_dup which is now changed to just increase the
4755 reference count instead of duplicating the data. The reference
4756 count is decresed by calling silc_packet_context_free that will
4757 free the data after the reference count hits zero.
4759 For now on the packet context and everything allocated into it
4760 (including the raw packet from network) must be freed by calling
4761 the new silc_packet_context_free function. Added also new function
4762 silc_packet_context_alloc that must be used now to allocate the
4763 context. This also means that if a routine is asynchronous from
4764 silc_[client/server]_packet_parse_type the packet context must
4765 be duplicated by calling silc_packet_context_dup. Otherwise it
4766 gets free'd after silc_[client/server]_packet_parse_type returns.
4767 Also, one must remember that if packet is duplicated then its
4768 reference count must be decresed by calling the free function as
4769 many times as it was duplicated.
4771 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4772 from both client and server.
4774 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Made joining to a channel working in router environment.
4778 * Cleaned up JOIN command on server side and create function
4779 silc_server_command_join_channel internal routine to make the
4782 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Changed silc_command_pending list to SilcDList. Also, added
4785 `ident' field to SilcServerCommandPending structure to identify
4786 the reply and to call correct callback.
4788 Added silc_server_command_pending_check function to replace the
4789 corresnponding macro. The silc_command_pending list is not
4792 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4793 to set identifier to previously allocated Command Payload. It
4794 is used to set identifier for command when resending Command
4797 * Added silc_command_payload_encode_payload to encode Command
4798 Payload buffer from SilcCommandPayload structure.
4800 * Added silc_argument_payload_encode_payload to encode Argument
4801 payload buffer from SilcArgumentPayload structure.
4803 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Changed WHOIS command to support router connection on server side.
4806 The whois request is always sent to router unless the server is
4807 standalone server. After server has received the reply from the
4808 router will it send the reply to the client.
4810 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4811 broadcast received broadcast packet. The function is used only
4812 by router. The broadcast packet is always sent to the router's
4815 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4816 render given ID to printable string, for log files for example.
4818 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Made basic router to router connections working. At least they
4821 can now connect to each other but nothing really works the way
4822 they are supposed - yet.
4824 * Added new initiator token to RouterConnection configuration
4825 file in silcd/serverconfig.[ch]. It is used to tell whether we
4826 are the initiator to the remote router or whether we'll expect
4827 the other end to connect.
4829 * Moved registering of listener task to silc_server_init, hence
4830 the server starts listenning as soon as it is run, even if it
4831 does not have connections to other routers. Let's see how well
4834 * Changed default connection retry timeouts for more suitable in
4837 * Removed cipher and such arguments from silc_idlist_add_client
4838 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4839 Added new function silc_idlist_add_data to add the keys and stuff
4842 * Added SilcIDListData structure and added it to SilcClientEntry
4843 and SilcServerEntry as their first field in the structure. This
4844 way we can explicitly cast the ID entries to the SilcIDListData
4845 structure and get common data for the entries. In past, we had
4846 to first check what type of connection it is and then cast it to
4847 correct ID entry type. Now, we can directly cast the opaque
4848 pointer to the SilcIDListData (no matter what ID entry it actually
4849 is) and get the data needed.
4851 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4854 in some circumstances even if threre were timeout tasks, though not
4855 IO tasks, but tasks anyway. Now fixed.
4857 * Defined SilcServerConnection structure to hold connection specific
4858 stuff about directly connected servers and routers. The definition
4859 is currently in silcd/server_internal.h. I thought about having
4860 a bit more important role fro this struct but for now it is used
4861 only when connecting to other server (or router actually).
4863 * Added connecting retry support in server when connecting to
4864 router(s). The retry feature implement exponential backoff
4865 algorithm. Also, added SilcServerParams structure to hold default
4866 parameters for server. For now, it include these retry settings
4867 and are hard coded. After server is moded to be as Silc Server
4868 Library this structure will be more important.
4870 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Changed client librarys channel->clients table to SilcList and
4873 changed code accordingly.
4875 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Changed client's channel table to SilcList and changed code
4878 accordingly. Also changed SilcChannelClientEntry to include back-
4879 pointer to the channel so that client entry can use that structure
4880 as list as well and we have fast cross-reference to the channel.
4881 This change dramatically decreased the complexity of channel
4882 handling with client entry and vice versa (removed one extra
4883 loop when searching for channel entry from many functions).
4885 * Changed server->sim from table to SilcDList and changed code
4888 * NAMES command can now be used from user interface. It will show
4889 the user list on the channel, neatly.
4891 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4892 Code now saves realname of the user if it becomes available.
4894 * Renamed configure.in to configure.in.pre and made ./prepare
4895 script to automatically add correct version string to
4896 configure.in which it creates from configure.in.pre.
4898 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * NAMES command reply now shows users mode with the nickname when
4903 * Moved silc_client_ch[u]mode[_char] functions from
4904 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4905 place sucks, they are utility functions and should be in some
4908 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4910 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4913 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Added TRQ (efficient deque and list library) into lib/trq. This is
4918 a very good list library that is currently used in the SILC. Defined
4919 SilcList API over the library because I didn't like the API very
4920 much. See lib/trq/silclist.h for the API and examples of how to
4921 use the API. Fixed various places in the code to use the new
4922 SilcList API. The SilcList is meant for lists that has a structure
4923 already defined as a list. It is not suitable to add just some
4924 context to the list (in TRQ, the context is the list actually).
4926 So, I defined SilcDList that can be used for the purpose where
4927 predefined list structure does not exit. This can be used as
4928 such list. Now some context just can be added to the SilcDList.
4929 Currently this list is not used in the SILC just yet, though there
4930 are a lot places where this can replace dynamically allocated
4931 tables and I will fix these places, later, to use SilcDList.
4932 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4933 and use TRQ internally).
4935 Also fixed some annoying warning messages that the original TRQ
4936 code generated. Also minor changes to TRQ's Makefile.in.
4938 * Added support for querying by Client ID to both WHOIS and
4939 IDENTIFY commands into server, as required by the protocol.
4941 * Removed method function pointers from SilcBuffer structure. They
4942 weren't used to anything and just increased the context size for
4943 no good reason. This change also made silc_buffer_alloc and
4944 silc_buffer_free functions inline functions.
4946 * Disabled command flooding detection support until it's fixed so
4947 that it accepts commands in but does not execute them more than once
4950 * Added silc_net_localhost(), to return local hostname, into
4951 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4952 that must be initialized before calling silc_client_init.
4954 * Added new function: silc_server_send_notify_on_channels to send
4955 notify messages to all channels client has joined. It is assured
4956 that the message is sent only once per client.
4958 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4959 lib/silcutil/silcutil.[ch] as silc_format function. The new
4960 function is generic and is used by server as well, not only by
4961 the logging routines.
4963 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4964 the provided version string was not acceptable. Added new function:
4965 silc_ske_check_version into lib/silcske/silcske.h. The function
4966 must be implemented by the application (client or server) and it
4967 does not reside in the SKE library. The function checks the version
4968 string remote end sent.
4970 * Added back pointers (to opaque context and to SilcSocketConnection)
4971 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4973 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4974 duplicate packet context structure.
4976 * Changed `notify' client operation to send same arguments as client
4977 receives from server except for ID's. ID's are mapped to correct
4978 ID entry and that is returned. Also, if channel entry is not sent
4979 by server but the notify is for channel the channel entry is sent
4980 to application (otherwise application doesn't know that it is for
4981 channel (library gets it from packet's Destination ID)).
4983 * Added silc_client_remove_from_channels into client library to
4984 remove a client from all channels it has joined to. Used when
4985 received SIGNOFF notify from server. Added also new function
4986 silc_client_replace_from_channels to replace old ID entry with
4987 new ID entry on all channels. Used when received NICK_CHANGE
4990 * Fixed ID Cache list handling in silc_idlist_get_client in
4991 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4992 to get (or query) client by ID.
4994 * Updated TODO list.
4996 * Added connection authentication status message defined by the
4997 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4998 support for these into the code in client and server side.
5000 * Added generic function silc_client_send_command to send any command
5001 with variable argument list. Application should use this function
5002 to send commands if the command functions provided by the library
5003 does not suite for the application's user interface needs.
5005 * Added new `failure' client operation. Application is notified about
5006 received failure packet if client is executing a protocol. In this
5007 case the protocol's execution has failed.
5009 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5010 is required by the protocol.
5012 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5013 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5016 * Added status flag to SilcSKE object to indicate realtime status
5017 of the SKE protocol.
5019 * Application receives now exactly same command reply arguments as
5020 the library receives from server. However, if ID is received the
5021 corresponding ID entry is returned to the application (eg. Client
5022 ID is mapped to correct SilcClientEntry entry and that is returned).
5023 Changed command_reply client operation due to this change.
5025 * Changed all ID's in commands and in command replys as ID Payloads.
5026 Change affected both client and server side codes.
5028 All ID's sent in SILC network (with execption of ID's in SILC
5029 Packet header) are sent in ID Payload to support variable length
5032 * Server now notifies nick changes and notifies all clients on
5033 the channels about the new nickname (about the new Client ID,
5036 * Implemented CMODE command to change channel modes. Supports all
5037 channel modes defined by the protocol specs except ban and invite
5038 lists. (Also, private channel key mode is supported but support for
5039 setting private channel key in client is missing, thus, this mode
5040 has no effect on client side (except that server requires that the
5041 client uses private channel key and normal channel traffic does not
5044 Also, invite mode works per se, but INVITE command does not work
5045 yet correctly, so you can set channel as invite only channel but
5046 inviting clients to the channel does not work (it is yet to be
5047 thought what's the best way to do it).
5049 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5050 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5051 Implemented CUMODE command to change user's mode on the channel.
5052 Supports all modes defined by the protocol specs.
5054 * Added NAMES command reply to return users modes on the channel.
5056 * Removed unnecessary and slow ciphers from lib/silccrypt.
5058 * Set SO_KEEPALIVE option to connection sockets by default.
5060 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5062 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5063 redefined the Notify Payload into protocol specs.
5065 * Added silc_id_payload_parse_id to get ID directly from raw
5068 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5071 accept searching by Client ID as well.
5073 * Added support for LEAVE and SIGNOFF notify types in client library.
5075 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5076 to parse ID Payload from raw data.
5078 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Added flags parameter into silc_ske_assemble_security_properties
5081 function in lib/silcske/silcske.[ch].
5083 * Changed notify client operation to fit better for notify messages
5084 sent by server. The notify payload received from server is now
5085 passed to the application (after parsing it to SilcNotifyPayload).
5086 It is application's responsibility to retrieve the arguments
5087 from the payload and show the message the way it wants. The message
5088 sent by server is implementation specific.
5090 * Changed public keys to comply with the protocol specification.
5091 Old public keys are not supported anymore and are not compatible.
5093 * Removed nickname from Channel Payload as the latest draft removed
5094 it. The client must resolve the nickname from the NAMES command
5095 reply received when it joined the channel.
5097 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5099 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Fixed some errors in protocol specification drafts.
5103 * Created lib/silccore/silcnotify.c to implement Notify Payload
5104 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5105 generic payloads described by protocol specifications. The file
5106 includes implementations for ID Payload and Argument Payload.
5108 * Changed Command Payload implementation to use the new Argument
5109 Payload. Changed command_xxxx_payload to command_payload_xxxx
5110 to comply with SILC coding conventions.
5112 * Added suppport for Argument Payload handling in Notify Payload
5113 implementation as protocol requires it. Added the new support
5114 into server and client lib as well.
5116 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Added support for multiple nicknames on same channel. [n] is
5119 added locally to the nickname if there are more than one same
5120 nicknames on the channel.
5122 * Server now sends all nicknames that matched WHOIS request.
5123 Client also shows the list received from server.
5125 * Added TOPIC command to client side. User can now set and show
5126 current topic on channel.
5128 * Added MOTD command to client and server. Also, server sends the
5129 motd when client connects to the server.
5131 * Changed version strings to comply ISO 8601.
5133 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Fixed protocol error handling in client library. It should now
5136 cope even if the SKE fails for some reason.
5138 * Made new protocol specification drafts for submitting to IETF.
5140 * Implemented TOPIC command to server in silcd/command.c.
5142 * Added two new notify types into lib/silccore/silcnotify.h:
5143 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5144 notify nickname change and topic setting/change on a channel.
5146 * API change of command_reply operation in client library. The
5147 application gets now the status type received from server as well.
5149 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5153 * Cras fixed and optimized the packet handling even further and
5154 it should work now. Minor change to the prototype of function
5155 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5157 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Added new function into lib/silcutil/silcschedule.[ch]:
5160 silc_schedule_with_fd to select() a specified fd. The function
5161 returns after timeout expires or data arrives or goes. The
5162 function is used by packet routines to wait that all data is
5163 received from network.
5165 * Fixed data reading from network in lib/silccore/silcpacket.c.
5166 The code now assures that all data is read from the fd and then
5167 continues packet processing. This was a bug fix since the code
5168 used to drop some data in some circumstances.
5170 * Added new function into lib/silcclient/client.[ch]:
5171 silc_client_start_key_exchange to start key exchange after
5172 connection has been established to server. The code internally
5173 now uses this funtion but its main purpose was to provide it
5174 for applications that perform their own connecting. After
5175 application has created a connection it merely calls this
5176 function to start the key exchange between client and server.
5177 The library takes care of everything else after that.
5179 Updated also lib/silcclient/README to explain the usage of
5182 * Do not send to application information that connection has
5183 been established. Application gets notified it by connect
5186 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Applied cras's patch to add silc_schedule_one function. The
5189 function runs scheduler once and returns.
5191 * Fixed the scheduler after cras messed it up. The timeout
5192 handling works now as it's supposed to work.
5194 * Added into lib/silccore/ silcnotify.h to include notify
5195 message types support. Changed silc_server_send_notify*
5196 functions, in server.[ch], to support those new notify types.
5197 Added the support for the notify types into client library,
5198 as well. Added new notify client operation into ops.h in
5201 * Changed silc_server_packet_send_to_channel to send normal
5202 packets instead of just channel message packets. The function
5203 is now used to send the notify packets to channels. It is not
5204 used to send channel message packets anymore, as server never
5207 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5208 va_arg()s as it seems to require it nowadays. I guess, if SILC
5209 is compiled with older va_arg() the new code should work anyway.
5211 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Splitted core library. Core library (lib/silccore) includes
5214 now only SILC protocol specific core (and common) components.
5215 Created new utility library (lib/silcutil) that includes more
5216 generic purpose stuff. The stuff for util library was taken
5217 from the old core library. This was minor and easy split.
5219 * Created SILC Client Library (lib/silcclient) that includes
5220 implementation of the SILC client without user interface. This
5221 was major move from silc/ directory. The code has been changed
5222 so that it is transparent towards the user interface. The
5223 silc/ directory includes now the same user interface as before
5224 and it uses the new client library. Read lib/silcclient/README.
5225 Basicly, the client library performs everything else related
5226 to SILC except user interface handling. Also, configuration
5227 files are considered to be part of user interface and library
5228 does not handle them.
5230 This change also changed a lot of structures, function naming etc.
5231 Most important change was that SilcClientWindow object was
5232 renamed to SilcClientConnection in the client library. Created
5233 also new file lib/silcclient/ops.h. Also added new files
5234 silc/local_command.[ch] and silc/client_ops.[ch].
5236 All these changes were made to make it easier for user interface
5237 designers to create what ever user interface for the SILC client
5240 It is also expected that the server will be moved to lib
5241 directory as well and SILC Server Library will be created;
5242 sometimes in the future.
5244 * Removed Local commands from lib/silccore/silccommand.h as
5245 they are application specific and new client library does not
5246 handle any of those anymore.
5248 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5249 old client implementation in silc/.
5251 * Added support for callback functions in SILC_LOG_* macros.
5252 Application can now set its own callbacks that will be called
5253 instead of using the default functions that will always print
5254 the debug messages to stderr (or stdout). Also, debugging can
5255 now be disabled by setting silc_debug to FALSE and re-enabled by
5256 setting it to TRUE. Note, that logging will still work even
5257 if debugging is disabled.
5259 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5260 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5261 silc_log_reset_debug_callbacks.
5263 * To enable debugging in silc client one must give now -d
5264 option on command line.
5266 * Changed silc_schedule_init to automatically allocate task queues
5267 if they are not allocated before calling it.
5269 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added GMP 3.1 into math library.
5273 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5276 a channel in SILC network. The packet is used by servers and
5277 routers to notify other routers that user has left a channel.
5278 This little feature was missing until now. Added the feature
5279 to protocol specification as well.
5281 Added functions: silc_server_send_remove_channel_user and
5282 silc_server_remove_channel_user into server.[ch].
5284 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5285 lib/silccore/silcpacket.h. However, they are not implemented
5288 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Fixed joining to a channel and sending channel messages
5291 between server and router. The channel message sending should
5292 now work inside a cell.
5294 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5296 * Fixed the private message sending between server and router.
5297 The private message sending should now work inside a cell.
5299 * Added silc_server_replace_id into server.[ch] to replace
5300 existing ID in the SILC network.
5302 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5303 and silc_idlist_replace_server_id into idlist.[ch] in server.
5305 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Fixed the server to server connections. Server can again now
5308 connect to router. Router to router connections probably does
5311 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Added dynamic protocol registering support. Now protocols can
5314 registered and unregistered on the fly. Patch by cras.
5316 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Added lib/contrib directory to hold routines that some platforms
5319 don't have but are needed by SILC.
5321 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5322 into lin/contrib to provide getopt() and getopt_long() for
5323 those who don't have it.
5325 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Added AWAY command to client. When away message is set and
5328 client receives a private message packet the client automatically
5329 replies to the sender with the away message.
5331 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5332 bug seemed to be the cause of recent problems when compiling
5335 * Added version detection support to SKE protocol specification
5336 and added the new changes to the SKE implementation as well.
5337 There were other minor changes in the SKE protocol as well.
5339 Many changes in lib/silcske/silcske.[ch] and in
5340 lib/silcske/payload.[ch].
5342 * Added ^U functionality, clear input line. Patch from cras.
5344 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Mainly small bugfixes on core library. Fixed some debugging
5347 logging and buffer overflow in silclog.c.
5349 * Updated config.sub and config.guess on the distribution tree.
5351 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Added command lagging support in server. Client may execute
5354 commands now only once in two seconds.
5356 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Optimized packet reception. MAC computation and checking is now
5359 also more optimized. A lot previously duplicated code is now
5360 used as generic by both client and server.
5362 * Fixed key pair generation in clientutil.c
5364 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Added into lib/silccore/silcbufutil.[ch] new function;
5367 silc_buffer_realloc.
5369 * Moved generic packet sending/encryption functions to
5370 lib/silccore/silcpacket.[ch] from client and server. Some
5371 rewriting of the functions.
5373 * Moved all generic packet reception/decryption functions to
5374 lib/silccore/silcpacket.[ch] from client and server. The
5375 packet processing is now much cleaner in both client and server.
5376 These were major changes in both client and server.
5378 * Created many common functions in server to do packet sending.
5379 Previously code were duplicated a lot, this has been removed
5382 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Rewrote major parts of the ID cache system. Don't know
5385 whether it is better now or not but at least the API is more
5388 * Major rewrite on ID cache stuff on client because of the ID
5389 cache API changes. Added idlist.c to client.
5391 * Also major rewrite on ID cache stuff on server as well.
5392 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5393 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5394 in hand, instead they are all put into the ID cache system now.
5395 All server_idlist_* routines uses ID cache now instead of
5396 traversing its own lists (those lists does not exist anymore).
5397 SilcIDList though still exists. Also, SilcXXXEntry's are
5400 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Finally made the SKE implementation compliant to the protocol
5403 specification. All mp integers are now binary encoded as
5404 opposed being HEX encoded.
5406 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5409 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5410 functions: silc_[encode/decode]_pem. Also added function
5411 silc_encode_pem_file to PEM encode with newlines ('\n') for
5414 * SILC public keys are now encoded either PEM or binary. Same
5415 option is for private keys as well. By default private keys
5416 are binary encoded and public keys PEM encoded. Silly HEX
5417 encoding were removed.
5419 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5420 function to create fingerprints.
5422 * Fixed a bug in SHA1; does not change the original data anymore.
5424 * Partly implemented INFO command on client and server side.
5425 Fixed CLEAR command. Changes to SERVER command; show current
5426 server(s) when giving command without arguments. Added
5427 VERSION command to client.
5429 * Added check to server that unregistered connections cannot
5430 execute commands (unless it is specificly allowed).
5432 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Fixed screen refresh.
5436 * Fixed channel joining bug from client. On some circumstances
5437 client tried to join to a channel it had already joined.
5439 * Added public key verification process into client's protocol.c.
5440 The client now verifies the public key from user and saves
5441 it into ~./silc/serverkeys/ directory.
5443 Added into: clientutil.[ch]: silc_client_verify_server_key.
5445 * Changed SKE protocol's silc_ske_initiator_finish function
5446 to accept callback function that verifies the received public
5447 key. Removed old silc_ske_verify_public_key function.
5449 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5452 silc_pkcs_private_key[_data]_set.
5454 * Made the password and public authentication more cleaner in
5455 server's protocol.c.
5457 * Removed historic and obsolete protocol `channel_auth' from
5458 both client and server.
5460 * Removed wrong way of sending command status messages from
5461 server to client in server's command.c. The old way violated
5462 protocol specification.
5464 Changes to silccore/silccommand.[ch]: removed
5465 silc_command_encode_status_payload -> not needed anymore,
5466 changed silc_command_encode_payload_va to accept extra
5467 argument on variable argument list. The argument type must
5468 now be provided to the function. Also, added new function:
5469 silc_command_encode_reply_payload_va which is same as
5470 normal command_encode_payload_va except command status type
5471 is provided as extra argument.
5473 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Added ~./silc directory handling. The directory includes the
5476 public and private keys for the client.
5478 Added silc_client_check_silc_dir, silc_client_create_identifier
5479 and silc_client_load_keys.
5481 * Implemented SILC protocol compliant public key. Added public
5482 and private key saving to and loading from files.
5484 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5485 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5486 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5487 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5488 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.

5491 silc_pkcs_load_[public/private]_key.
5493 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added silc_server_get_route (route.[ch]) to get connection
5496 data for the fastest route for given ID.
5498 * Implemented INVITE command on client and server. The command
5499 were re-defined in the SILC Protocol Specification and the
5500 implementation now complies with the specification.
5502 * Implemented PING command on client and server.
5504 * Implemented NAMES command on client and server. The server side
5505 supports currently only normal server not router server yet.

5516 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
