3 * Added SilcServerEntry context into the client library
4 to represent one server. The INFO command now allocates
5 these to save the resolved server info. For now on the
6 client library will also keep information about servers,
7 connected and resolved with INFO.
9 The INFO command now allocates the SilcServerEntry context
10 and saves the server info there. The COMMAND_REPLY in
11 the INFO now returns the parameters to application in
12 same order as defined in the protocol specification.
14 The entries are cached in the client->server_cache.
16 * The INFO command is now issued after received the Client ID
17 from the server. Affected file lib/silcclient/client.c.
19 * The CMODE_CHANGE notify may now return also an SilcServerEntry
20 to the application as the mode changer might be server.
21 It is guaranteed that NULL is not returned anymore to the
22 application. Affected file lib/silcclient/client_notify.c.
24 The ID Type is now also passed to the application so that
25 it can check whether the returned entry is SilcClientEntry
28 Added new function silc_client_get_server_by_id to return
29 the server entry by ID. Affected files are the
30 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
32 * Do not create the channel in the Irssi SILC Client when issuing
33 the JOIN command but when received the sucessful JOIN command
34 reply. Otherwise the channel might get created even though we
35 could not join it. The Affected file is
36 irssi/src/silc/core/[silc-channels.c/client_ops.c].
38 * Fixed a channel joining bug in router. The router must also
39 check the channel modes, invite and ban lists etc. when serving
40 the JOIN command sent by normal server. Affected file is
41 silcd/command.c. The router now resolves the client's
42 information from the server who sent the JOIN command if it
43 does not know it, and processes the JOIN command only after
46 * Changed the SilcCommandCb to take new argument; void *context2.
47 Affected file lib/silccore/silccommand.h
49 The second argument in the command callbacks in the server now
50 includes the SilcServerCommandReplyContext if the command was
51 called as pending command callback from the command reply.
52 Otherwise it is NULL. When called as pending the status of the
53 command reply will be checked and if it was erronous the
54 error will be sent to the original sender of the command.
55 This way the client always receives the error messages even
56 though the server was actually the one who received the error
57 when it resent the command to router, for example. Affected
58 files silcd/command[_reply].[ch].
60 * Fixed sending WHOWAS command's error message to client if
61 the requested client could not be found. It was missing.
64 * Changed the CMODE and CUMODE commands reply arguments in the
65 protocol specification. The Channel ID is now sent in both
66 of the commands to identify the channel. Implemented this
67 new feature to the client and server. Affected files
68 lib/silcclient/command_reply.c and silcd/command.c.
70 * Made better checks for invite and ban lists in the JOIN
71 command in server. Affected file silcd/command.c.
73 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
75 * The server now performs the incoming host IP/DNS lookup
76 using the silc_socket_host_lookup and thus does not block
77 the server anymore. Affected file silcd/server.c.
79 * Completed the multi-thread support for SILC Scheduler in
80 the lib/silcutil/silcschedule.c.
82 * Fixed the configure.in.pre to detect the pthread correctly
85 * Fixed a deadlock in silc_task_queue_wakeup in the file
86 lib/silcutil/silctask.c.
88 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Added new function silc_schedule_wakeup that is used in
91 multi-threaded environment to wakeup the main thread's
92 schduler. It needs to be used when a thread adds a new task
93 or removes a task from task queues. After waking up, the
94 scheduler will detect the task queue changes. If threads
95 support is not compiled in this function has no effect.
96 Implemented the wakeup mechanism to both Unix and WIN32
97 systems. Affected files are lib/silcutil/silcschedule.[ch],
98 lib/silcutil/unix/silcunixschedule.c and the
99 lib/silcutil/win32/silcwin32schedule.c.
101 * Added new function silc_task_queue_wakeup to wakeup the
102 scheduler by the specified task queue. Affected file
103 lib/silcutil/silctask.[ch].
105 * The silc_socket_host_lookup_start now wakes up the scheduler
106 after adding the timeout task. Affected file is
107 lib/silcutil/silcsockconn.c.
109 * The silc_socket_host_lookup is synchronous now if the threads
110 support is not compiled in. However, the callback is still
111 called asyncronously through the scheduler, anyway. Affected
112 file lib/silcutil/silcsockconn.c.
114 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
116 * Added new function silc_socket_host_lookup to perform
117 asynchronous IP and FQDN lookups for the socket connection.
118 Affected files lib/silcutil/silcsockconn.[ch].
120 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
122 * Added SILC_MUTEX_DEFINE to define the mutex on environments
123 that may or may not compile the mutex support in.
125 Changed the silc_mutex_alloc interface. It allocates the
126 mutex now to the sent pointer and returns TRUE or FALSE.
128 Affected file lib/silcutil/silcmutex.h.
130 * Wrote the SILC Task Queue interface to support multi-threads.
131 Affected file lib/silcutil/silctask.[ch].
133 * Wrote the SILC Scheduler to support multi-threads. Affected
134 file lib/silcutil/silcschedule.c.
136 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
138 * Implemented the SILC Mutex API and SILC Thread API for WIN32
139 in lib/silcutil/win32/.
141 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Defined SILC Mutex API and SILC Thread API and implemented
144 them for Unix. Affected files are
145 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
146 lib/silcutil/unix/silcunixmutex.c and
147 lib/silcutil/unix/silcunixthread.c.
149 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
151 * Fixed the silc_server_remove_clients_by_server's channel
152 key re-generation. The hash table handling was incorrect
153 and would not work with many channels. Affected file is
156 * Fixed some memory leaks around the server code.
158 * Rewrote the silc_server_get_users_on_channel to support IPv6
159 based Client ID's. Affected file silcd/server.c.
161 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
162 specification. However, a separate document must be written
163 to define the detailed signing procedure and the payload
164 associated with the flag. Defined the flag to the
165 lib/silccore/silcchannel.h as well.
167 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
169 * Changed the dynamic tables to static size tables in the
170 lib/silccrypt/silchmac.c.
172 * Removed GCC dependencies from the code. A patch by cras.
174 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
176 * Do not show the error "Error receiving packet bla bla"
177 in server if it really was not an error (-2 means that reading
178 is pending). Affected file silcd/server.c.
180 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
182 * Fixed a possible crash in silc_server_remove_clients_by_server
183 in silcd/server.c. Fixed there also some memory leaks.
185 * Fixed the silc_idlist_replace_client_id. It could replace
186 wrong key in the hash table. Affected file silcd/idlist.c.
188 * Do not check whether there are global users on the channel
189 if the channel->global_users is FALSE. Affected functions
190 silc_server_remove_from_one_channel and
191 silc_server_remove_from_channels in silcd/server.c. Also,
192 do not check if the removed client is local as we can be
193 sure that global client was not removed from the channel
194 and checking for global users is not needed.
196 * The silc_server_remove_clients_by_server now re-generates
197 the channel keys correctly for those channels that had
198 clients removed from them. Affected file silcd/server.c.
200 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
202 * Found the reason of random crashes in the server. We weren't
203 ignoring the SIGPIPE signal (which can be sent in write())
204 and it crashed the server. Affected file silcd/silcd.c.
206 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Assure that sock->user_data is not NULL in the function
209 silc_server_packet_send in silcd/packet_send.c.
211 * Disconnect the remote connection if it could not be added
212 to any ID lists in the server. The affected file is
215 * Check in silc_server_packet_send[_real/dest] that the
216 socket is not disconnecting and ignore the data if it is.
217 Affected file silcd/packet_send.c.
219 * Define inline to __inline on native WIN32 compilation.
220 Affected file includes/silcwin32.h.
222 * Added some explicit type casts for inline code since MSVC
223 require them. Affected files lib/silcutil/silcbuffer.h,
224 lib/trq/silcdlist.h and lib/trq/silclist.h.
226 * Print warning in log files from now on if the packet
227 decryption fails. Affected file silcd/server.c.
229 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
231 * Changed the `say' client operation's interface to accept
232 new `type' argument to indicate the type of the message sent
233 by the library. The application may filter the library's
234 messages according the type. The affected file is the
235 lib/silcclient/silcapi.h.
237 * Added two new functions to lib/silcclient/silcapi.h:
238 silc_client_del_client and silc_client_del_client_by_id.
239 Affected file lib/silcclient/idlist.c.
241 * Moved the clientincludes.h from includes/ to silc/ and
242 serverincludes.h from includes/ to silcd/.
244 * The modes for the CMODE and CUMODE are now passed as
245 uint32 for application with COMMAND_REPLY. The affected
246 file is lib/silcclient/command_reply.c.
248 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
250 * /WHOIS without arguments shows client's own information.
251 Affected file lib/silcclient/command.c.
253 * Changed PING to not accept any arguments. The specs
254 says that client can ping only the connected server so
255 requiring an argument is not needed. Affected file is
256 lib/silcclient/command.c.
258 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Fixed a fatal bug in private message sending and reception
261 encryption and decryption when using private message keys.
262 The implementation was incorrect and did not follow the
263 specification. It causd that some of the message were
264 lost since it did not use the sending and receiving keys
265 as the protocol suggests. This has been fixed and will cause
266 incompatibilities with older clients when sending private
267 message encrypted with private message keys. Affected files
268 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
269 and various other in Irssi SILC Client.
271 Added `responder' boolean argument to the functions
272 silc_client_add_private_message_key[_ske] to indicate when
273 the key is added as responder or initiator of the key
276 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
278 * Removed the silc_ske_check_version function and created
279 a SilcSKECheckVersion callback. Added also a function
280 silc_ske_set_callbacks that is now used to set all SKE
281 callbacks. The callback functions are not given to
282 the SKE functions anymore, but this function is used to
285 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
287 * Added `silc_version' argument to the silc_client_alloc
288 to define the version of the application for the library.
289 The library will use the version string to compare it
290 against the remote host's (usually a server) version
291 string. Affected file lib/silcclient/silcapi.h
293 * Added the KE protocol context to Key Agreement context
294 in client library so that we can abort the SKE if it
295 is in process when we get timeout. Affected file is
296 lib/silcclient/client_keyagr.c.
298 * Do not resolve the client ID forever if it returns in the
299 first time that such client does not exist. This was done
300 for example with private message. Affected file is
301 lib/silcclient/client_prvmsg.c.
303 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Do not add regex.h for WIN32. The affected file
306 includes/silcincludes.h.
308 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
309 not work yet 100%. It generates the DLL's automatically
310 when compiling with --with-win32 under cygwin.
312 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
314 * lib/contrib/regex.c is not compiled on WIN32.
316 * Added silc_net_get_socket_opt function to the
317 lib/silcutil/silcnet.h.
319 * Added includes/silcwin32.h for WIN32 specific includes
322 * Do not use ptime structure or any of the posix process
323 functions on WIN32 in lib/silccrypt/silrng.c.
325 * Added silc_gettimeofday to provide generic function
326 for struct timeval on all platforms. Added the function
327 to lib/silcutil/silcutil.h.
329 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
331 * Moved the lib/silccore/silcsockconn.[ch] to the utility
332 library as they clearly belong there. As a plus side we
333 can make the actual socket connection routines platform
336 Added also new generic function silc_socket_read and
337 silc_socket_write (that used to be silc_packet_[read/write].
338 The implementation of these are platform specific.
340 * Added WIN32 specific routines of silc_socket_[read/write]
341 to lib/silcutil/win32/silcwin32sockconn.c.
343 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
345 * Added preliminary support for native WIN32 compilation under
346 cygwin (using the -mno-cygwin option for GCC) to the
347 ./configure.in.pre. The --with-win32 now prepares the
348 compilation for native WIN32.
350 * Rewrote the SILC Scheduler interface in the file
351 lib/silcutil/silcschedule.h. The scheduler is now context
352 based and does not have anymore any global static scheduler.
353 Moved the Unix scheduler to the lib/silcutil/unix/ directory
354 and created lib/silcutil/win32 directory for WIN32 based
357 * Added Unix specific network routines to the
358 lib/silcutil/unix/silcunixnet.c and the old
359 lib/silcutil/silcnet.c includes now only generic routines.
361 Added WIN32 specific network routines to the
362 lib/silcutil/win32/silcwin32net.c.
364 * Added Unix specific utility functions from the
365 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
367 * Added WIN32 SILC Scheduler to the file
368 lib/silcutil/win32/silcwin32schedule.c. The code is of course
371 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
373 * Do not handle JOIN notify in the server if the target client
374 is not registered (idata->registered == FALSE). The affected
375 file is silcd/packet_receive.c.
377 * Update the nickrec->founder in event_cumode in the Irssi SILC
378 client. Affected file irssi/src/silc/core/silc-channels.c.
380 * Fixed the CUMODE_CHANGE notify handling in the server when
381 server and router are announcing their clients on channels.
382 Now the mode changes are saved and notified correctly. The
383 affected file is /silcd/packet_receive.c.
385 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
386 They really did not replace the cache entry in the ID Cache.
387 Now they do that. Affected file silcd/idlist.c.
389 * Fixed the KICK notify handling in the Irssi SILC client to
390 update the channel records so that the kicked client does not
391 appear to be on the channel. The affected file is
392 irssi/src/silc/core/silc-channels.c.
394 * Always update the conn->current_channel when executing command
395 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
397 * Fixed the KILL notify handling in Irssi SILC client to remove
398 the killed client on all channels.
400 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Fixed the silc_parse_command_line to remove extra spaces
403 from the start and end of the arguments. Affected file is
404 lib/silcutil/silcutil.c.
406 * Cancel and free any active protocol in the function
407 silc_server_close_connection. Affected file silcd/server.c.
409 * Cancel and free any active protocol in the function
410 silc_client_close_connction. Affected file is
411 lib/silcclient/client.c.
413 * Do not execute the KILL command for clients that are in
414 history (ie. they are not in the network). Affected file is
417 * Fixed KILL notify handling, client does not crash anymore.
418 Affected file irssi/src/silc/core/silc-channels.c.
420 * Reduced the default packet buffer size from 2048 to 1024 in
421 lib/silccore/silcpacket.c.
423 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
424 counter to the SKE context that is incresed when the SKE library
425 performs async operation outside the library. If the outside
426 process frees the SKE context and FREED status will be set
427 and the library will detect after the sync operation that the
428 libary is freed. The affected files are
429 lib/silcske/silcske[_status].[ch].
431 * Resolve the client entry information in the function
432 silc_client_channel_message to assure that NULL pointer is not
433 passed as client entry to the application. */
435 * Fixed the task timeout calculation to assure that there is
436 never negative timeouts. The affected file is
437 lib/silcutil/silcschedule.c.
439 * Fixed the channel user mode notification sending in server.
440 It was sent point-to-point to the router (or to server by router)
441 but it needs to be destined to a channel. The routines now
442 supports sending the channel user mode notifys to the channels
443 when announcing clients and channels. Affected files are
444 silcd/server.c and silcd/packet_receive.c.
446 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
447 It did not actually replace the old channel entry in the cache.
448 Affected file lib/silcclient/client_notify.c.
450 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Fixed a possible crash in silc_packet_send_prepare. It now
453 assures always that there is enough space in the buffer and
454 at the tail area of the buffer (for MAC).
456 Fixed the inbound buffer reallocation in silc_packet_read.
457 It was old code and did not handle the reallocation correctly.
460 The affected file is lib/silccore/silcpacket.c.
462 * Fixed buffer overflow in silc_parse_nickname in the file
463 lib/silcutil/silcutil.c.
465 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * make install generates new server keys only if there is not
470 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
473 Added check that if the NOREPLY is set then we will not send
474 the away message. This avoids infinite loop of away messages
475 if both clients are away. The affected file is
476 lib/silcclient/client_prvmsg.c.
478 * Fixed client crash if /NICK was given without arguments.
479 Affected file lib/silcclient/command.c.
481 * Server does not send the invite list in INVITE command back
482 to the client if the list was not altered. Added this notion
483 to the protocol spec as well. Affected file silcd/command.c.
485 Fixed possible crash in INVITE command by checking the
486 value of silc_server_get_client_route command.
488 * Fixed the INVITE notify type handling. The arguments are now
489 taken in correct order and client does not crash. The affected
490 file is irssi/src/silc/core/silc-channels.c.
492 Removed the "Inviting xxx to channel" message from the
493 client library away and let the application handle it.
494 Affected file lib/silcclient/command.c. Added that message
495 to Irssi SILC client's message formats.
497 * Fixed CMODE command crash in client. It now checks the
498 amount of arguments correctly and does not crash. The affected
499 file is lib/silcclient/command.c.
501 * Do not create new channel automatically in silc_channels_join
502 but check whether the channel by that name already exists.
503 Affected file irssi/silc/core/silc-channels.c.
505 * Do not send the SERVER_SIGNOFF to router if the disconnected
506 entity was the router. Affected file silcd/server.c.
508 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
509 SILC client as it was missing from there.
511 Added the handling of the KICK notify to the Irssi SILC client
512 as it was missing. Added "you have been kicked" message to
513 Irssi SILC client's message modules formats.
515 Added the handing of the KILL notify to the Irssi SILC client
516 as it was missing. Added the kill message module formats
519 The affected file is irssi/src/silc/core/silc-channels.c.
521 * The router did not save the channel mode the server announced.
522 Affected file silcd/packet_receive.c.
524 * Fixed a possible crash in INFO command in server. If the
525 server did not provide the server info it crashed. Affected
526 file silcd/command.c.
528 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Fixed the GETKEY command in the server to check also the
531 global list. Otherwise the GETKEY would not work correctly
532 in normal SILC server. Affected file silcd/command.c.
534 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Fixed GETKEY crash, it crashed if the command did not succseed.
538 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
541 is now real and not just an macro interface to GMP.
543 Removed the entire GMP from the source tree and imported new
544 NSS MPI library instead. Reason for removing GMP is that it is
545 extremely large and compiles extremely slow. The NSS MPI
546 is only a few files and compiles in less than 10 seconds.
547 The speed is also about the same as GMP. The MPI is imported
550 If the system has GMP installed we will still use the GMP.
551 If it is not then the NSS MPI will be compiled.
553 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
555 * Merged a long nickname (127 characters long) crash bugfix from
556 Irssi CVS tree. Affected file irssi/src/core/misc.c.
558 * Merged a freed memory reference bugfix from Irssi CVS tree.
559 Affected file irssi/src/core/commands.c.
561 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Added the server's public key sving and verification to the
564 server when performing the SKE. This was missing and the
565 remote server's (or router's) public key was accepted without
566 checking whether we have it previously or trust it at all.
567 Affected file silcd/protocol.c.
569 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Check in the silc_server_timeout_remote if protocol is active
572 and make sure that the protocol's final callback is called so
573 that all memory if freed. Affected file silcd/server.c.
575 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * silc_server_whois_send_reply crashed the server if the nickname
578 was 127 characters long. Affected file silcd/command.c.
580 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Added sanity check to the silc_server_new_client. If the hostname
583 is provided inside username then check that the provided hostname
584 really is the same as the resolved one. If the hostname was not
585 resolved then check it from the public key. Affected file is
586 silcd/packet_receive.c.
588 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
589 if the server disconnected us and the connection is not valid
590 anymore. Affected file irssi/src/silc/core/silc-channels.c.
592 * Moved the silc_client_[chmode|chumode|chumode_char] away from
593 the library to the lib/silcutil/silcutil.[ch].
595 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
597 * Close log file after open. Affected file
598 lib/silcutil/silclog.c.
600 * Check whether sock == NULL in silc_client_send_packet and return
601 if it is. Affected file lib/silcclient/silcclient.c.
603 * Check rec->entry == NULL in the Irssi SILC Client before
604 sending the channel message. Affecte file is
605 irssi/src/silc/core/silc-servers.c.
607 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Merged a splitted window bugfix from Irssi CVS tree. The
610 affected file is irssi/src/fe-text/textbuffer-view.c.
612 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
613 It did not print nickname.
615 * Improved the distributions system a bit.
617 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
620 irssi/src/fe-text/gui-window.c.
622 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
623 to in-active server. The affected file is
624 irssi/src/silc/core/client_ops.c.
626 * Resolve the client in USERS command reply if the entry does
627 not have username resolved. The affected file is
628 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
629 command to WHOIS command to really resolve stuff. The USERS
630 is not used any more in any critical section so WHOIS can
631 be used even though it might be slower than IDENTIFY.
633 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
636 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Changed the protocol API a bit more consistent in the
639 lib/silccore/silcprotocol.[ch].
641 * Changed the following headers to ROBODoc format:
643 lib/silccore/silcpayload.h
644 lib/silccore/silcprotocol.h
645 lib/silccore/silcsockconn.h
647 All core library headers are now formatted.
649 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Fixed a bug in Irssi SILC client; do not show that you are
652 server/router operator if you really are not. Affected file is
653 irssi/src/silc/core/client_ops.c.
655 * Renamed silc_command_free_payload to silc_command_payload_free.
656 Affected file lib/silccore/silccommand.h
658 * Added silcmath.h to include the prototoypes of various routines
659 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
662 * Changed the following headers to ROBODoc format:
664 lib/silccore/silcchannel.h
665 lib/silccore/silccommand.h
666 lib/silccore/silcid.h
667 lib/silccore/silcidcache.h
668 lib/silccore/silcmode.h
669 lib/silccore/silcnotify.h
670 lib/silccore/silcpacket.h
671 lib/silcmath/silcmath.h
673 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * Added checking to the server code not to start the server if
676 ciphers and stuff are not configured properly. Affected files
677 silcd/serverconfig.[h] and silcd/server.c.
679 * Changed the layout of the header files of the public interfaces
680 in the SILC libraries. The new layout supports ROBODoc
681 documentation tool (and some others) so that it is easy to create
682 a library reference manual. All the other headers and source
683 code must still follow the CodingStyle document. Also source
684 code must not include these ROBODoc stuffs, only the headers.
685 Furthermore, all public interface headers must now be named
686 by using `silc' prefix, example: silcapi.h, silccipher.h.
687 Some files were renamed due to this. All the other headers
688 must not be used as public interfaces. I will update the
689 CodingStyle document later. Changed following headers, so far:
691 lib/silcclient/silcapi.h
692 lib/silccore/silcauth.h
693 lib/silccore/silcprivate.h
694 lib/silccrypt/silcdh.h
696 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
700 * Removed silc_client_packet_send_flush from the client library
701 as it is not needed. Affected file lib/silcclient/client.[ch].
703 * Added printing of message of unresolved authentication method
704 to the Irssi SILC client. Added it to the module formats.
705 Removed the same message from the client library.
707 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Added new distribution feature, DISTLABEL. Every distribution
710 can define own preprocessor label that can be used in the
711 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
712 file distributions, acconfig.h.pre and prepare.
714 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Added Makefile.defines_int to include the actual definitions
717 for Makefile.defines.in. Tested the new distribution system,
718 created distributions and tested installation.
720 * Added AWAY message printing to the Irssi SILC client. Added
721 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
723 * Added SCONNECT command to call the SILC's CONNECT command.
724 Cannot use CONNECT directly since Irssi uses that internally.
725 Affected file irssi/src/silc/core/silc-servers.c.
727 Added ACTION local command. It is same as ME command but takes
728 the channel as mandatory argument.
730 Rewrote some of the Irssi's help files to suite for SILC
733 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Added Makefile.defines[.in] that should for now on be included
736 in all Makefile.am file in the source tree. That file includes
737 all common compilation definitions for SILC source tree.
739 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Minor changes to the ./prepare script to change the package
742 name according the distribution name to the configure.in.
744 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Created new distribution system. Added file `distributions'
747 that defines all the distributions that can be created out of
748 the SILC source tree. The ./prepare script now reads that
749 file to determine how to prepare the distributions. The
750 first argument to the ./prepare is the name of the distribution
751 and second is the version of the distribution. If given
752 without arguments it creates the default (toolkit) distribution
753 with the default version (defined in ./prepare).
755 All Makefile.am files that are subject to the distributions
756 are now named as Makefile.am.pre. These are ./Makefile.am
757 and lib/Makefile.am. Others may be changed later.
759 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Added invite list, ban list, some key management and connection
762 error message printing to module formats in the Irssi SILC client.
764 * Added new silc_client_set_away_message to set the away message
765 that is back to the person who sent private message. The
766 affected file lib/silcclient/silcapi.h and the
767 lib/silcclient/client_prvmsg.c.
769 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Fixed the private message sending in the Irssi SILC client,
772 added local command KEY to the Irssi SILC client.
774 Added key management and key agreement message formats to the
775 irssi/src/fe-common/silc/module-formats.[ch].
777 Added USERS (alias WHO) printing, server/router operator
778 indication and LIST command printing to the module formats.
780 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Fixed channel joining notify handling, cumode notify handling
783 from Irssi SILC client.
785 * Added SILC specific module-formats to the Irssi SILC client so
786 that SILC specific message hilighting, colors etc is possible.
787 Affected file irssi/src/fe-common/silc/module-formats.[ch].
789 Added channel mode, channel user mode, actions, notices,
790 whois and whowas printing to the the module-formats.c.
792 * Fixed a bug in channel deletion in the server. The channel
793 is not left to the cache even if the channel founder auth mode
794 is set when there are no users anymore on the channel. Affected
797 * The silc_net_localhost now resolves the entire hostname including
798 the domain name. Affected file lib/silcutil/silcnet.c.
800 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Changed the ask_passphrase client operation to be ascynchronous.
803 It has now a completion callback and a context that the
804 application must call after it has got the passphrase from
805 the user. Affected files lib/silcclient/silcapi.h,
806 lib/silcclient/protocol.c, lib/silcclient/command.c and
809 Added SilcAskPassphrase callback that the application calls
810 to deliver the passphrase to the library.
812 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
813 The public key verification and especially a certificate
814 verification is asynchronous procedure.
816 Added new SILC_SKE_STATUS_PENDING status to indicate the
817 request is pending and a callback will be called to finalize
820 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
821 indicate that remote end did not send its public key (or
822 certificate), even though we require it. Added check for this
823 condition in the SKE. This was a security bug, now fixed.
825 Defined new SilcSKEVerifyCbCompletion callback that is called
826 when the verification process is completed.
828 The affected files lib/silcske/silcske_status.h and
829 lib/silcske/silcske.[ch].
831 * Changed the verify_public_key client operation to be async
832 as well. Defined SilcVerifyPublicKey callback that is used to
833 indicate the success of the public key verification process.
835 Changed the server and client to use the new async client
838 * Changed the Irssi SILC client's internal scheduler to be called
839 twice as many times as it used to be. As a result the client
840 should be a bit faster now. Affected file is
841 irssi/src/silc/core/silc-core.c.
843 * Added support to Irssi SILC client of asynchronous public key
844 verification and passphrase inquiry. Affected file is
845 irssi/src/silc/core/silc-core.c.
847 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Do not say "You have left channel %s" in client library.
850 Moved it to the application. Affected files are
851 lib/silcclient/command.c and silc/client_ops.c.
853 * Fixed silc_client_get_clients. Command context was not
854 duplicated and was freed memory in the callback. Affected
855 file lib/silcclient/idlist.c.
857 * Do not say "you are now talking..." on JOIN command in the
858 client library. The appliation must handle it.
860 * Do not say ".. changed topic to" in command reply in the
861 client libary. The application must handle it.
863 * Fixed TOPIC command sending in the client library.
865 * Fixed a memory leak in silc_client_command_free in the file
866 lib/silcclient/command.c.
868 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Imported a modified version of Irssi client to the source tree.
871 The Irssi will be used to create a new client called
872 Irssi SILC. Imported to irssi/.
874 Added silc_core_init_finish function to the Irssi. Affected
875 file irssi/configure.in.
877 A lot changes in the Makefile.ams around the irssi tree.
879 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Do not rehash if the new size is same as the old size of the
882 hash table, in the silc_hash_table_rehash*. The affected file
883 lib/silcutil/silchashtable.c.
885 * Replaced hash_table_del_by_context calls from the server
886 (when channel->user_list and client->channels) to the
887 hash_table_del as it is sufficient and faster.
889 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Added silc_hash_table_list, silc_hash_table_get and the
892 SilcHashTableList structure to provide an alternative way to
893 traverse the hash table. The affected files are
894 lib/silcutil/silchashtable.[ch].
896 * Changed the server's idlist routines to use the hash table
897 routines to optimize the code.
899 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Replaced the client entry's `channel' list and channel entry's
902 `user_list' list to hash tables for optimized lookup. Changed
903 the code to use the hash table interface around the code.
904 Affected file lib/silcd/idlist.[ch].
906 * Added `auto_rehash' boolean argument to the function
907 silc_hash_table_alloc to indicate whether the hash table should
908 auto-rehash when it thinks is appropriate time. It will
909 increase the hash table size if the there is twice as much
910 entries in the table than the size of the table, and will
911 decrease the size if there are twice as less entries than
912 the size of the table.
914 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Fixed silc_xxx_get_supported to not crash at some circumstances.
918 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * silc_idcache_purge_by_context deletes the entry now by context
921 as it is supposed to do. Affected file lib/silccore/idcache.c.
923 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
924 client is not anymore valid (WHOWAS givens the info) and not
925 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
927 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Removed the `data' and `data_len' arguments from the ID Cache
930 interfaces and added `name' argument. ID Cache does not handle
931 anymore the binary data only a names associated with given ID.
933 * When hashing a Client ID with silc_hash_id the entire ID is
934 not hashed anymore, instead only the hash of the Client ID is
935 hashed. This way we can access the Client ID from the cache
936 with Client ID but with the hash of the ID (which is a hash of
937 the nickname) as well without any difference in performance.
939 Added also silc_idcache_find_by_id_one_ext to do one on one
940 searching when we have the actual ID. Added also function
941 silc_hash_client_id_compare. The affected files are
942 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
944 * When hashing the name associated with a ID it is always done
945 in lowercase. This way we can access the cache without worrying
946 about case-sensitivity, even though, for example nicknames are
949 * Fixed a bug in server with channel message sending. It put
950 wrong ID type as destination ID. The affected file
953 * silc_idcache_del_by_context now deletes from all hash tables
954 by context. Affected file lib/silccore/idcache.c.
956 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Changed the client library to use the new ID Cache interface.
959 Changes around the source tree.
961 * Added silc_hash_table_rehash_ext to rehash with specific
962 hash function. Affected file lib/silcutil/silchashtable.[ch].
964 * Added silc_hash_string_compare to compare two strings in the
965 hash table. Affected file lib/silcutil/silcutil.[ch].
967 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added new function silc_idcache_del_by_context into the
970 lib/silccore/idcache.[ch].
972 * Changed the server's ID list routines to use the new ID Cache
973 interface. Changes around the source tree.
975 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * Added silc_hash_table_del[_by_context]_ext functions in to the
978 lib/silcutil/silchashtable.[ch].
980 Removed silc_hash_table_find_all* routines and added new
981 silc_hash_table_find_foreach to replace them.
983 Added silc_hash_table_replace_ext function as extended
984 replacing function. Separated the simple hash table interface
985 from the extended hash table interface in the file
986 lib/silcutil/silchashtable.h.
988 * Fixed minor bugs and changed it to use some of the new
989 hash table functions in lib/silccore/idcache.c
991 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Added new function silc_hash_table_find_all to return all keys
994 in the hash table by the specified key. As the hash table is
995 collision resistant it also makes it possible to have several
996 duplicate keys in the hash table. This function may be used to
997 find all of the keys from the hash.
999 Added user_context arguments to the SilcHashFunction,
1000 SilcHashCompare and SilcHashDestructor to deliver user specified
1003 Added new fuctions silc_hash_table_find[_all]_ext to do
1004 extended lookup with specified hash and compare functions and
1005 specified user contexts.
1007 Added new function silc_hash_table_add_ext to add the key
1008 with specified hash function and user context.
1010 Added new function silc_hash_table_foreach to traverse all
1011 entrys in the hash table. Added SilcHashForeach callback
1014 Added new function silc_hash_table_del_by_context to delete
1015 the entry only if the context associated with the key matches.
1017 Affected files are lib/silcutil/silchashtable.[ch].
1019 * Removed silc_hash_[server/client/channel]_id and added just
1020 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1021 silc_hash_id_compare to compare two ID's using as the hash table
1022 comparison function. Added also silc_hash_data to hash
1023 binary data and silc_hash_data_compare to compare it.
1025 * Removed silc_idlist_find_client_by_hash as it is not needed
1026 anymore. Affected file silcd/idlist.[ch].
1028 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1029 to use internally the SilcHashTable. The new ID Cache is a lot
1030 faster than the old one. Some of the ID Cache interface was also
1031 rewritten and obsolete and stupid functions were removed.
1033 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Added entry_count field to the SilcHashTable to keep the number
1036 of the entries in the table. Implemented the function
1037 silc_hash_table_rehash. Added new function
1038 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1040 Fixed a minor bug in silc_hash_table_free.
1042 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1043 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1044 into the lib/silcutil/silcutil.[ch].
1046 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Implemented a collision resistant hash table into the
1049 lib/silcutil/silchashtable[ch]. See the header and the source
1050 for the SilcHashTable API.
1052 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Merged dotconf version 1.0.2 into lib/dotconf.
1056 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Do not compile anything in lib/silcsim/* if the SIM support
1059 is not enabled. The tree should now compile without problems
1062 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Compiled the SILC under cygwin. Compiled and tested briefly
1065 without problems. More tests needed. The SIMs didn't compile
1068 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1070 * Fixed possible crash in silc_get_username in the
1071 lib/silcutil/silcutil.c.
1073 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Fixed a va_arg in silc/client_ops.c.
1077 * Oops, RC5 routines were named AES and caused some problems
1078 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1080 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1082 * Added new SilcIDIP structure into the lib/silccore/id.h and
1083 replaced the old `ip' fields from all SILC ID's to that type.
1084 This is a step towards IPv6 support.
1086 The silc_id_get_len takes now the ID as an extra argument.
1087 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1088 both IPv4 and IPv6 based ID's.
1090 The affected files are lib/silccore/id.[ch] and other files
1091 around the tree using these routines.
1093 * Removed the ID length arguments in server from various
1094 silc_server_send_notify_* routines -> they are not needed
1097 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Fixed memory leak in silc_encode_pem_file in the file
1100 lib/silcutil/silcutil.c.
1102 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Check minor version as well in the SKE. Affected files are
1105 silcd/protocol.c and lib/silcclient/protocol.c.
1107 * Added --identifier option to the server so that an identifier
1108 can be when creating the public key for the server. Affected
1109 file is silcd/silcd.c.
1111 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1112 lib/silccrypt/silcpkcs.c.
1114 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1116 * Register default ciphers and stuff when using -C option with
1117 the server. Affected file sildc/silcd.c.
1119 * Put back the servers public key filename format, it is better
1120 than the new one. For now, the client keys are saved with the
1121 new filename format. The affected file silc/client_ops.c.
1123 * Implemented the Cipher API for the rest of the ciphers that
1124 did not implement it or implemented it the wrong way.
1126 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Register default ciphers and stuff when using the -S option
1129 in the client. Affected file silc/silc.c. Same also when
1130 creating new key pair with -C option.
1132 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1134 * Fixed the silc_verify_public_key client operation function to
1135 save the public keys differently. The fingerprint is now
1136 used as filename and not the hostname. This way also the
1137 client keys are saved uniquely and not with hostnames. The
1138 affected file is silc/client_ops.c.
1140 * Trimmed the silc_hash_fingerprint function to remove extra
1141 whitespaces from the end of the fingerprint. The affected
1142 file is lib/silccrypt/silchash.c.
1146 * Added silc_cipher_register_default function to register all
1147 default ciphers. It can be used when configuration files
1148 does not exist and the application does not want any specific
1149 ciphers in any specific order.
1151 The SilcDList is now used as silc_cipher_list dynamically
1152 allocated cipher list. Removed the static list all together
1153 and now all ciphers must be allocated to the dynamic list.
1154 The silc_cipher_alloc routine was changed to check only the
1157 All silc_cipher_* routines that used to return int returns
1160 The affected files lib/silccrypt/silccrypt.[ch].
1162 * The same thing was done to silc_hash_* as for silc_cipher_*
1163 routines. Affected files lib/silccrypt/silchash.[ch].
1165 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1166 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1167 Added also silc_pkcs_[un]register[_default] functions.
1168 Removed the data_context from the PKCS API.
1170 * Added silc_hmac_register_default function to register default
1171 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1172 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1173 to unregister all hmacs at once.
1175 * Register the default ciphers, hash functions, PKCSs and HMACs
1176 if client's configuration file does not exist. The affected
1179 * The client did not load the hash functions from the SIM
1180 modules at all. Added support for this. Affected file is
1181 silc/clientconfig.c.
1183 * When decoding public key with silc_pkcs_public_key_decode, check
1184 the supported algorithm only if PKCS are registered. Affected
1185 file lib/silccrypt/silcpkcs.c. The same was done with the
1186 silc_pkcs_private_key_decode.
1188 * Fixed the SILC List routines to keep the list always in order.
1189 It used to change the list's order when traversing the list but
1190 not it preserves the order. Affected file lib/trq/silclist.h.
1192 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Added the client library to use the SilcSocketConnection's
1195 reference counter (by silc_socket_dup) to prevent the bug that
1196 the socket object may be freed underneath async operation.
1198 * The name resolv library checking fixes in the configure.in.pre.
1201 * Created new version of the protocol drafts for future
1202 development. The -03 drafts are the ones that will be changed
1203 in the trunk now and the -02 will remain as they are.
1205 * Send list of CUMODE notifys to the router when announcing
1206 the channel users to the router. Affected file silcd/server.c.
1207 If the router receiving channel founder CUMODE for a channel
1208 that already has channel founder it will send CUMODE notify
1209 to the sender to remove the channel founder rights from the
1210 announced client. Affected file silcd/packet_receive.c.
1212 * The CUMODE notify may now use Server ID as well as the entity
1213 who changes the mode. Updated protocool specs.
1215 * Updated INSTALL and README files.
1217 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * New web pages in the http://silc.pspt.fi. The pages was
1224 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Implemented the [DenyConnectin] config section in the server.
1227 Added silc_server_config_denied_conn to check whether incoming
1228 connection is denied. Affected file silcd/serverconfig.[ch].
1230 * Do not check the ports when checking the incoming configuration
1231 data if the port is 0, meaning any. Affected file is
1232 silcd/serverconfig.c.
1234 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Fixed buffer overflow in silc_string_compare in the file
1237 lib/silcutil/silcutil.c.
1239 * Fixed double free in silc_server_command_leave in the file
1242 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Fixed the version checking in the server. Affected file is
1247 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * Fixed the configuration data fetching when accepting new
1250 connections in the server. Affected file silcd/server.c.
1252 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Added `sender_entry' argument to the function
1255 silc_server_packet_relay_to_channel so that we can check
1256 whether some destination actually belongs to the same route
1257 the sender belongs (ie, we must not resend the packet to the
1258 sender). Affected file silcd/packet_send.[ch].
1260 * Added `servername' field to the SilcClientEntry in the server
1261 to hold the name of the server where client is from. Affected
1262 file is silcd/idlist.h.
1264 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Moved the channel message encrypting in the router betwen
1267 router connections from silc_server_channel_message to the
1268 silc_server_packet_relay_to_channel since we want to check
1269 whether we have anybody channel before encrypting anything.
1270 Affected files silcd/packet_[receive/send].c.
1272 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Fixed the [AdminConnection] server config section to support
1275 multiple entries. Affected file silcd/serverconfig.c.
1277 * Added support into the server to check the validity of the
1278 incoming connection before executing any KE or authentication
1281 * The connection configuration is now saved to the KE and
1282 connection auth protocol contexts and not fetched anymore in
1283 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1285 * The local hosts listenning address and port is also resolved
1286 now when starting the server. We want to have the socket object
1287 to include the real address and port for the listener. Added
1288 new function silc_net_check_local_by_sock into the files
1289 lib/silcutil/silcnet.[ch].
1291 * Fixed a broadcast bug in server -> do not broadcast if we
1294 * Fixed a routing bug. Do not route broadcast packets ever.
1295 Broadcast packets must be processed always and not routed since
1296 they may be destined to some other host than yourself and thus
1297 would get routed without no good reason. Affected file is
1300 * Added function silc_server_config_is_primary_route to check
1301 whether primary router connection has been configured (a router
1302 configuration that we are initiating). If there is not, we
1303 will assume that there is only two routers in the SILC network
1304 and we will use the incoming router connection as our primary
1305 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1307 * Changed the order of the broadcasting. Broadcast _after_ the
1308 packet has been processed not before. Affected file is
1311 * Fixed a [ClientConnection] parsing bug. The port was never
1312 parsed correctly thus resulting to port 0. Affected file
1313 silcd/serverconfig.c.
1315 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1316 argument and did not set the broadcast packet flag. Affected
1317 file silcd/packet_send.c. Fixed same bug in the function
1318 silc_server_send_notify as well.
1320 * If we receive NEW_ID packet for our own ID in the server, ignore
1323 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Removed the nickname from the Private Message Payload.
1328 Updated the code and the protocol specs.
1330 * Updated protocol specs for submitting to the IETF.
1332 * Tweaked the Random Number Generator a bit. Affected file
1333 lib/silccrypt/silcrng.c. Exported a new function
1334 silc_rng_[global]_add_noise which can be used to add more
1337 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1339 * Do not parse packets with different timeout when protocol
1340 is active -> may cause problem with rekey. Affected file
1343 * When server receives signoff notify it must not create
1344 new channel key if the client is on any channels since the
1345 sender of the signoff notify will create it.
1347 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Added printing of error messages during SKE protocol from the
1350 failure packet sent by server during SKE. Affected file
1353 * Removed the client's failure_callback handling with timeout
1354 and handle it immediately when received.
1356 * The SKE library returned wrong type in SUCCESS and FAILURE
1357 packets. They must be 32 bit MSB not 16 bit MSB.
1359 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1361 * Ok, rewrote the logic of the re-key and now it seems to work.
1362 I tested it on high traffic with frequent re-keys without
1363 problems. Added hmac_receive (and renamed hmac to hmac_send)
1364 in SilcClientConnection in lib/silcclient/client.h and
1365 in SilcIDListData in silcd/idlist.h. Also, removed the
1366 SilcPacketParserContext's cipher and hmac fields as they are
1367 not needed anymore and actually caused some problems when
1368 the ciphers and hmac's changed underneath the packet parser.
1370 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * If re-key protocol is active then process the incoming packets
1373 synchronously since we must assure that icoming packets encrypted
1374 with the old key is processed before the new keys is set to
1375 use. This is true other packets than for REKEY packets.
1376 Affected file silcd/server.c. The same was done to client library
1377 as well, affected file lib/silcclient/client.c.
1379 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Fixed bug in client and server to accept the force send if
1382 the packet is send from silc_[server/client]_packet_process
1383 function. Otherwise the packets are never delivered, oops.
1385 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * Disable force sending of packets when REKEY protocol is active.
1388 We must assure that no packet is sent directly when rekey is
1389 performed. All packets must be sent through packet queue.
1390 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1391 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1392 function is silc_[server/client]_packet_send_real to check
1395 * Replaced the SIM paths from example config files to
1396 /usr/local/modules. Also, make install creates now
1397 /usr/local/silc/logs directory to hold all the SILC server
1400 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Made the configure.in.pre work on Solaris. Patch by salo.
1404 * Made all ciphers compatible with non-x86 machines. Defined
1405 CBC mode macros into lib/silccrypt/ciphers_def.h.
1407 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Fixed the make install.
1411 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * When MAC computation fails the silc_packet_decrypt returned 0
1414 even though it was supposed to return -1. Fixed this. The
1415 affected file is lib/silccore/silcpacket.c.
1417 * Do not replace the config files in /etc/silc (in make install)
1418 if they already exist. Affected file ./Makefile.am.
1420 * Do not send re-key packets immediately but through packet queue.
1421 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1423 * Changed silc_net_check_host_by_sock to return FALSE if the
1424 IP/DNS could not be resolved. Though, it returns the IP address
1425 now even if it could not resolve it (but returns also FALSE).
1426 Affected file lib/silcutil/silcnet.[ch].
1428 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Added silc_pkcs_decode_identifier to decode the public key's
1431 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1432 Added also silc_pkcs_free_identifier. Added also new context
1433 SilcPublicKeyIdentifier.
1435 * Added -S option to the silc client. It is used to dump the
1436 contents of the specified public key file.
1438 * Changed the PKCS api to return the public key length when
1439 setting the public key.
1441 * Fixed a fatal bug in the public and private key file loading.
1442 Affected file lib/silccrypt/silcpkcs.c.
1444 * Execute the packet parsing for client with zero (0) timeout
1445 if the protocol is active. Affected file silcd/server.c.
1447 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Made the key generation options to the silcd program. Added
1450 -C option, equivalent to client's option.
1452 * Added new [ServerKeys] config section to the server. It
1453 configures the server's public and private key.
1455 * Defined generic Public Key Payload into the protocol
1456 specification to send specific type of public keys and
1459 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1460 public key or certificate.
1462 * Implemented the GETKEY command to the server and to the
1463 client library and on user interface.
1465 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1467 * Made preliminary `make install' work.
1469 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Added SilcServerRekey context into silcd/idlist.h.
1473 * Added the PFS support as defined in the specification to the
1474 SKE protocol. Affected files lib/silcske/*.c.
1476 * Added `ske_group' field to the SilcServerRekey context to hold
1477 the number of the SKE group that is used with PFS in re-key.
1478 Affected file silcd/idlist.h.
1480 * Added PFS re-key support to the server. Affected file is
1483 * Added silc_protocol_cancel to cancel execution of the next
1484 state of the protocol. Affected file is
1485 lib/silccore/silcprotocol.[ch].
1487 * Added the re-key support with and without PFS to the client
1488 library. Re-key is performed once in an hour, by default.
1490 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1491 Added silc_client_rekey_callback and silc_client_rekey_final.
1492 Affected files are lib/silcclient/protocol.[ch] and
1493 lib/silcclient/client.[ch].
1495 * Removed the `hmac_key' and `hmac_key_len' fields from the
1496 SilcClientConnection structure; not needed. Affected file is
1497 lib/silcclient/client.h.
1501 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Do not ask whether user wants to use the negotiated private key
1504 for private messages, just use it. Affected file is
1505 silc/local_command.c.
1507 * Added `send_enc_key' and `enc_key_len' fields to the
1508 SilcIDListData structure since they are needed in the re-key
1509 phase. Affected file is silcd/idlist.[ch].
1511 * Implemented the simple re-key protocol into the server.
1512 Affected files silcd/server.c and silcd/protocol.[ch]. The
1513 re-key will be performed once in an hour, by default.
1515 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1516 Added silc_server_rekey, silc_server_rekey_callback and
1517 silc_server_rekey_final.
1519 * Removed Tunneled flag from the protocol. Updated the code
1520 and the specifications.
1522 * Adde `pfs' field to the SilcIDListData to indicate whether
1523 the PFS is to be performed in the re-key. Affected file is
1526 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1529 int64 of at least the xintXX size. If void * is less that 4
1530 bytes uint32 * will be used. Defined bool as boolean.
1532 * Changed _ALL_ unsigned long and unsigned int to uint32,
1533 unsgined short to uint16 in the source tree.
1535 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1536 not handle clients that has entry->data.registered == FALSE.
1537 They are not in the network anymore. Affected file is
1540 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Implemented the sending of the SERVER_SIGNOFF notify in the
1543 server. Affected file is silcd/server.c.
1545 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1546 Added also silc_notify_payload_encode_args into the
1547 lib/silccore/silcnotify.[ch].
1549 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1550 Affected file silcd/packet_receive.c.
1552 * Implemented the SERVER_SIGNOFF notify handling in the client
1553 library. Affected file lib/silcclient/client_notify.c. Also,
1554 implemnted the printing of the SERVER_SIGNOFF info to the
1555 application. Affected file silc/client_ops.c.
1557 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1558 if the deleting was successful. Affected file silcd/idlist.[ch].
1560 * Added support for public key authentication in the connection
1561 authentication protocol in the client library. Affected file
1562 lib/silcclient/protocol.c.
1564 * Changed the server's silc_idlist_get_clients_by_* interface
1565 to support already allocated array so that new entries may be
1566 added to pre-allocated array. Affected file silcd/idlist.[ch].
1567 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1568 and command replies.
1570 * All command reply functions in the server now calls the
1571 pending command callback even if error occured. This way the
1572 error will be delivered to the client as well. Affected files
1573 silcd/command.c and silcd/command_reply.c.
1575 * Fixed INFO command to return local server's info if no server
1576 was provided. Affected file lib/silcclient/command.c.
1578 * Removed RESTART command for good. Updated the code and the
1581 * Rewrote parts of the task system. It is a bit simpler now.
1582 Removed unsued task priorities. The affected files are
1583 lib/silcutil/silctask.[ch].
1585 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Moved the USERS printing from the library to the application.
1588 Affected files lib/silcclient/command.c and silc/client_ops.c.
1590 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Added channel key re-key support. The re-key is perfomed
1595 only by the router and is done once in an hour. Added `rekey'
1596 field to the SilcChannelEntry in the server. Affected files
1597 silcd/server.c and silcd/idlist.h.
1599 * Added silc_task_unregister_by_context into the file
1600 lib/silcutil/silctask.[ch].
1602 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Added SILC_UMODE_GONE mode to indicate when the client is not
1605 present in the SILC network. Added also support to the local
1606 command AWAY that will set this mode. Added support of showing
1607 "xxx is gone" in WHOIS command. The USERS command shows the
1608 gone status as well.
1610 * Fixed setting server and router operator privileges in the
1611 server's UMODE command. Affected file silcd/command.c.
1613 * Merged the SKE KE1 and KE2 payloads into one payload. The
1614 new KE payload is equivalent to the old KE2 payload.
1616 Cleaned up the SKE Start Payload parsing. It now uses the
1617 simple buffer unformatting to do the parsing. A lot faster
1620 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1621 to the SKE that is used to indicate whether both of the SKE
1622 parties should perform authentication. By default only the
1623 responder performs authentication. By setting this flag also
1624 the initiator must do authentication. By default it is unset
1625 since in normal SKE case, client to server connection, only
1626 the responder should do authentication. When doing SKE between
1627 two clients both should perform authentication. Updated the
1628 code and the protocol specs.
1630 * A little fix to IDENTIFY command in the server. Search the
1631 client first by hash not nickname. Affected file is
1634 * Fixed the silc_client_close_connection to support closing
1635 the client to client connections wihtout deleting too much
1636 data. Affected file lib/silcclient/client.c.
1638 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1639 are received if protocol used to be active but is not anymore
1640 the application would crash due to NULL pointer dereference.
1641 Affected files silcd/server.c and lib/silcclient/client.c.
1643 * Added `hash' field to the SilcClientConnection to include
1644 the hash function negotiated in the SKE protocol.
1646 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1647 to set the channel founder authentication data. A client can
1648 claim the founder rights later by providing the authentication
1649 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1650 This way the channel founder can regain the channel founder
1651 privileges even it is left the channel. This works only on
1652 local server and the client must be connected to the same
1653 server to be able to regain the founder rights. Updated the
1654 protocol specs accordingly.
1656 Added support to the CMODE command in the client to set the
1657 founder auth data. Read the README to see how to set it.
1659 Added support to the CUMODE command to claim the founder
1660 rights. Read the README to see how to do it.
1662 Added support for the founder authentication to the Channel
1663 Entry in the server. Affected file silcd/idlist.h.
1665 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1666 server's CMODE command. Affected file silcd/command.c.
1668 * Added the following new functions into lib/silccore/silcauth.[ch]:
1669 silc_auth_get_method and silc_auth_get_data.
1671 * The server now saves the remote hosts public key to the
1672 SilcIDListData pointer. Affected file silcd/protocol.c.
1674 * The normal server now does not remove the channel entry from
1675 the cache if the founder authentication data is set. It used
1676 to remove it if the founder was the last one on the channel on
1677 the server and left the channel. The auth data is saved and
1678 if the channel is re-joined later the old entry is used with
1679 the old auth data. Affected files silcd/command_reply.c and
1682 * Removed the `pkcs' field from the SilcIDListData structure
1683 in the server; it is not used. Affected file silcd/idlist.h.
1685 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Fixed packet processing on slow links. Partial packets were
1688 never re-processed because the incoming data buffer was cleared
1689 by the application. Application must not directly clear the
1690 sock->inbuf, the packet processing routines handle it. Fixed
1691 this in client library and in server.
1693 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1695 * Fixed the WHOIS and IDENTIFY send reply function to really
1696 check whether to send list or just one entry. Affected file
1699 * Cleaned up the LEAVE command's channel key distribution. The
1700 affected file silcd/command.c.
1702 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1703 can enforce the channel mode as well. In that case the ID
1704 includes the ID of the server. The code now enforces the
1705 mode change if the router have different mode than the server.
1707 * The notify client operation with CMODE_CHANGE notify can now
1708 return NULL client_entry pointer if the CMODE was not changed
1709 by client. Application must check for this.
1711 * Added <Server ID> argument to INFO command to support server
1712 info fetching by Server ID.
1714 * Added silc_server_announce_get_channel_users to get assembled
1715 packets of channel users of the specified channel. Affected
1716 file silcd/server.[ch].
1718 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1719 was freed underneath the ID Cache.
1721 * Re-announce clients when the server received CHANNEL_CHANGE
1722 notify from the router. Affected file silcd/packet_send.c.
1724 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1727 crashed since it did not handle the fact that there is no cipher
1728 called "3" and didn't check the error condition. Now fixed.
1730 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1731 flag. It can be used to send message requests.
1733 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Implemented the RESTART command in the client.
1737 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1738 notice type messages. Added notice printing to the user
1741 * The channel keys are not re-generated if the channel's mode
1742 is PRIVKEY, ie private key on the channel exists. Affected
1743 files silcd/server.c and silcd/command.c.
1745 * Fixed a little bug in channel message delivery when channel
1746 private keys are set in the server. Affected file is
1747 silcd/packet_send.c.
1749 * Changed the setting on channel->on_channel = TRUE from the
1750 silc_client_save_channel_key to the JOIN command reply. The
1751 key payload is not received if the private channel key is set.
1752 Affected file lib/silcclient/command_reply.c and the
1753 lib/silcclient/client_channel.c.
1755 * When the CMODE_CHANGE notify is sent and the channel private
1756 key mode is removed the channel key must be re-generated in
1757 other cells as well. Added this support for the router in the
1758 silcd/packet_receive.c.
1760 * Added new local command NOTICE to send notice message on
1761 channel. Affected file silc/local_command.[ch].
1763 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1765 * Added new local command ME to the client. It is used to send
1766 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1767 some action. Affected file silc/local_command.[ch].
1769 * Changed channel_message and private_message client operations
1770 to deliver the message flags to the application. Added also
1771 the `flags' arguments to the silc_client_send_channel_message
1772 and silc_client_send_private_message functions. Affected file
1775 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Redefined the Private Message Payload to support private message
1778 keys and to support the new private message flags. Updated
1779 the protocol specs. Flags makes it possible to have for example
1780 CTCP style messages.
1782 * Added new type SilcPrivateMessagePayload and defined an API
1783 for it in the lib/silcclient/silcprivate.[ch].
1785 * Tested private message private keys successfully. Tested the
1786 private message key set, unset and list commands with the new
1789 * Redefined the Channel Message Payload to include the channel
1790 message flags (equal with private message flags) to support
1791 for example CTCP style messages.
1793 * Defined some of the message (for channel and private message)
1794 flags. Updated the protocol specs and added the flags to the
1795 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1797 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Added SilcKeyAgreementStatus type to the key agreement routines
1800 to indicate the current status and error if one occured.
1801 The status types are defined in the lib/silcclient/silcapi.h.
1803 * Added new local command KEY that is used to set and unset private
1804 keys for channels, set and unset private keys for private messages
1805 with remote clients and to send key agreement requests and
1806 negotiate the key agreement protocol with remote client. The
1807 key agreement is supported only to negotiate private message keys,
1808 it currently cannot be used to negotiate private keys for channels,
1809 as it is not convenient for that purpose.
1811 * Fixed a minor pending callback setting bug in the function
1812 silc_client_get_client_by_id_resolve, now the function works.
1813 Affected file lib/silcclient/idlist.c.
1815 * Added function silc_net_get_local_port to get local bound
1816 port by socket. Added to lib/silcutil/silcnet.[ch].
1818 * Added `sockets' and `sockets_count' fields to the SilcClient
1819 object. They hold the sockets of the listenning sockets in
1820 the client. Listenning sockets may be for example the key
1821 agreement server. Affected file lib/silcclient/client.[ch].
1822 Added functions the silc_client_add_socket and the
1823 silc_client_del_socket. They are exported to the application
1826 * Added ~./silc/clientkeys to support other client's public keys.
1828 * Renamed verify_server_key client operation to verify_public_key
1829 and added one argument to indicate the type of the connection
1830 (server, client etc.).
1832 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Added silc_server_connection_auth_request to handle the
1835 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1836 silcd/packet_receive.[ch].
1838 * Added silc_server_send_connection_auth_request into the
1839 silcd/packet_send.c to send the connection auth request packet.
1841 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1844 * Fixed the public key authentication in responder side in the
1845 server. The `auth_data' pointer includes the SilcPublicKey
1846 not the path to the public key. Affected file silcd/protocol.c.
1848 * Implemented the public key authentication in the initiator side
1849 in the server. Affected file silcd/protocol.c.
1851 * Removed the [RedirectClient] config section from the server
1852 configuration. Is not needed and I don't want to implement it.
1854 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Cleaned up the CMODE command in the server. It now works
1857 correctly and supports all the modes defined in the protocol.
1858 Affected file is silcd/command.c.
1860 * Added `hmac_name' field to the SilcChannelEntry in the server
1861 to hold the default HMAC of the channel. It can be set when
1862 creating the channel (with JOIN command). Affected files
1865 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1866 type to indicate the change of the current cipher and hmac
1867 on the channel. Client can safely ignore the <cipher> argument
1868 (if it chooses to do so) since the CHANNEL_KEY packet will
1869 force the channel key change anyway. The <hmac> argument is
1870 important since the client is responsible of setting the new
1871 HMAC and the hmac key into use.
1873 * Fixed the CMODE command in the client library as well.
1875 * Tested CMODE command in router environment successfully.
1877 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Show the version of the remote client (or server) when connecting
1880 to the server. It is logged to the log file. Affected file
1881 is silcd/protocol.c.
1883 * Fixed the KILLED notify handling in the client library. The
1884 client must be removed from all channels when receiving the
1887 Also, do not remove the client entry when giving the KILL
1888 command but when the KILLED notify is received.
1890 * Removed silc_idlist_find_client_by_nickname from the server.
1891 Not needed anymore. Affected files silcd/idlist.[ch].
1893 * Implemented the CHANNEL_CHANGE notify type handling to the
1894 server. Affected file silcd/server.c.
1898 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Added silc_server_send_notify_invite to send the INVITE
1901 notify between routers.
1903 * Implemented the INVITE command correctly to the server.
1905 * Implemented the INVITE notify type handling in the server.
1907 * Implemented the INVITE command to the client library and on the
1910 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Added function silc_server_get_client_resolve to find the
1913 client entry by ID from all ID lists and then resolve it
1914 (using WHOIS) if it cannot be found. Affected file is
1917 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Implemented the BAN command to the client library.
1921 * The JOIN command in the server now checks the invite list
1924 * Changed the silc_command_reply_payload_encode_va and the
1925 silc_command_payload_encode_va to support that if argument is
1926 NULL it ignores and checks the next argument. Affected file
1927 lib/silccore/silccommand.c.
1929 * Added silc_server_send_notify_ban to send the BAN notify
1930 type between routers.
1932 * Chaned the silc_notify_payload_encode to support that if
1933 argument is NULL it ignores and checks the next argument.
1934 Affected file lib/silccore/silcnotify.c.
1936 * Tested ban lists in router environment successfully.
1938 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Implemented BAN command to the server, in silcd/command.[ch].
1942 * Removed the BAN and INVITE_LIST modes from the CMODE command
1945 * Added function silc_string_match to regex match two strings.
1946 Affected files lib/silcutil/silcutil.[ch].
1948 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Redefined parts of the SilcChannelEntry in the server to support
1951 the new ban and invite lists.
1953 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Redefined the INVITE command. The same command can be used to
1956 invite individuals to the channel but also to manage the invite
1957 list of the channel (to add to and remove from the invite list).
1958 Updated the protocol specs.
1960 * Added new command SILC_COMMAND_BAN that can be used to manage
1961 the ban list of the channel. Updated the protocol specs.
1963 * Removed the channel modes: the SILC_CMODE_BAN and the
1964 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1965 in the CMODE command. The equivalent features are now available
1966 using INVITE and BAN commands. Updated the protocol specs.
1968 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1969 in the network about change in the current ban list. The notify
1970 type is not used by the client.
1972 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1973 support the invite lists.
1975 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Added new function silc_string_regexify that converts string
1978 including wildcard characters into regex string that can
1979 be used by the GNU regex library. Added into the file
1980 lib/silcutil/silcutil.[ch].
1982 Added silc_string_regex_combine to combine to regex strings
1983 into one so that they can be used as one regex string by
1984 the GNU regex library. Added into the file
1985 lib/silcutil/silcutil.[ch].
1987 Added silc_string_regex_match to match two strings. It returns
1988 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1990 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Imported GNU regex to the soruce tree into lib/contrib.
1993 Fixed some compiler warning from the regex.c.
1995 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Fixed MOTD command in the server to work in router environment.
1999 * Fixed the MOTD command in the client library to support
2000 the server argument in the command.
2002 * Added `nickname_len' argument to the silc_idlist_add_client
2003 in the server, as the `nickname' argument may be binary data
2006 * Added silc_idlist_get_channels to return all channels from
2009 * Implemented LIST command to the server. Affected file is
2012 * Implemented the LIST command to the client library and on the
2015 * Added [<user count>] argument to the LIST command reply.
2016 With private channels the user count is not shown.
2018 * Updated TODO and README.
2020 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * The client entry's data.registered must be TRUE even with
2023 global client entry on global client list. The data.registered
2024 is used to check whether the client is anymore in the network,
2025 for example with WHOWAS command so it must be valid.
2027 * Fixed the WHOWAS command in the server. It now actually works
2028 in router environment. Added function into silcd/command_reply.c
2029 silc_server_command_reply_whowas_save.
2031 * Added silc_idlist_purge function to the silcd/idlist.c
2032 to periodically purge the ID Cache.
2034 * Fixed INFO command in the server. It works now in router
2035 environment. Added <server name> argument to the INFO command
2036 reply. Updated the protocol specs.
2038 * Fixed minor bug in silc_idcache_purge to not purge if the
2039 expire value is zero.
2041 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2042 they were buggy because of the WHOWAS information.
2044 * Fixed local command MSG to handle the async resolving of
2045 the remote client properly. It used to fail the first MSG.
2046 Affected file silc/local_command.c.
2048 * Added `data_len' field to SilcIDCache context.
2050 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Update TODO. Todo in commands in the server.
2054 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2057 used by routers as broadcast packet to inform other routers
2058 about the changed user mode.
2060 Implemented the notify handling in the server. Affected file is
2061 silcd/packet_receive.c. Added the function
2062 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2064 * Added new generic Channel Payload and deprecated the New Channel
2065 Payload. The New Channel Payload is now the generic Channel
2068 * Added new argument `mode' to the silc_server_send_new_channel
2069 as it is required in the Channel Payload now.
2071 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2072 and created a new and real SilChannelPayload to represent the
2073 new generic Channel Payload. Implemented the encode/decode
2074 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2076 * Added silc_server_get_client_channel_list to return the list
2077 of channels the client has joined for WHOIS command reply.
2078 Affected file silcd/server.[ch].
2080 * Implemented the channel list sending in the WHOIS command reply
2081 in server and in the client.
2083 Implemented the channel list displaying on the user interface
2084 as well. Affected file silc/client_ops.c.
2086 * Added silc_channel_payload_parse_list to parse list of Channel
2087 Payloads. It returns SilcDList list of SilcChannelPayloads.
2088 Client for example can use this function to parse the list of
2089 channels it receives in the WHOIS command reply. The caller
2090 must free the list by calling silc_channel_payload_list_free.
2091 Affected files lib/silccore/silcchannel.[ch].
2093 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Added one new argument <user mode> to the WHOIS command reply
2096 to return the mode of the user in SILC. Updated the protocol
2099 Implemented it to the server and client.
2101 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Fixed the mode printing on the user interface on joining.
2104 Affected file silc/client_ops.c.
2106 * Implemented the UMODE command and user modes in general to the
2107 client library and to the user interface.
2109 * Implemented the UMODE command to the server.
2111 * The server now sends UNKNOWN_COMMAND error status if client sends
2112 unknown command. Affected file silcd/command.c.
2114 * All server commands now handle the command identifier the right
2115 way when sending the command reply to the client. The client can
2116 use to identify the command replies with the identifier.
2118 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Added silc_server_get_client_route to resolve the route to
2121 the client indicated by the client ID. Affected file is
2124 * Added silc_server_relay_packet as general function to relay
2125 packet to arbitrary destination. This deprecates functions
2126 like _send_private_message_key, _relay_notify etc. Affected
2127 file is silcd/packet_send.[ch].
2129 Removed silc_server_send_key_agreement,
2130 silc_server_send_private_message_key and
2131 silc_server_packet_relay_notify functions from the file
2132 silcd/packet_send.[ch].
2136 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2137 server. Affected file silcd/packet_receive.[ch].
2139 * Implemented the KILL command to the client. Implemented the
2140 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2141 Affected files lib/silcclient/command[_reply].c and
2142 lib/silcclient/client_notify.c. Implemented the KILL notify
2143 printing in the user inteface.
2145 * Fixed a lot silc_parse_nick memory leaks from the client
2146 library in the file lib/silcclient/command.c.
2148 * Changed the silc_server_send_notify_on_channels's `sender'
2149 argument from SilcSocketConnection to SilcClientEntry to
2150 check the sender as entry and not as connection object and not
2151 to send to the client provided as argument. The affected file
2152 is silcd/packet_send.[ch].
2154 * The notify packets that are destined directly to the client used
2155 to not to be processed by the server. Now changed that and the
2156 server processes all notify packets. After relaying the packet
2157 to the client the notify packet is processed in the server.
2159 * The silc_server_free_client_data now checks whether there is
2160 pending outgoing traffic for the client and purges the data to
2161 the network before removing the client entry.
2163 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2166 an client is killed from the SILC Network. Updated the protocol
2169 Added new function silc_server_send_notify_killed to the
2170 silcd/packet_send.[ch].
2172 * Added function silc_server_packet_relay_notify to relay notify
2173 packets that are destined directly to a client. In this case
2174 the server does not process the notify packets but merely relays
2175 it to the client. Affected file silcd/packet_send.[ch].
2177 Added also silc_server_packet_process_relay_notify to check
2178 whereto relay the notify. Affected file is
2179 silcd/packet_receive.[ch].
2181 * Implemented the KILL command to the server.
2185 * Added the backup schema desgined last fall to the protocol
2186 specs for everyone to see. The specification is in the
2187 *-spec-xx.txt draft and the packet type definitions for the
2188 backup routers is in *-pp-xx.txt draft. Thusly, added also
2189 new packet type SILC_PACKET_CELL_ROUTERS.
2191 * A big security problem in the implementation discovered. The
2192 signoff of an client did not cause new channel key generation
2193 which it of course should've done. The channel keys must be
2194 always re-generated when client leaves (or signoffs) the channel.
2195 The silc_server_remove_from_channels funtion now handles
2196 the channel key re-generation.
2198 * Added `sender' argument to the silc_server_send_notify_on_channels
2199 to not to send the client provided as argument. Affected file
2200 silcd/packet_send.[ch].
2202 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Implemented OPER and SILCOPER commands into the server and
2207 * Added silc_auth_verify and silc_auth_verify_data to verify
2208 the authentication directly from the authentication payload.
2209 It supports verifying both passphrase and public key based
2210 authentication. Affected file lib/silccore/silcauth.[ch].
2212 * Added `hash' field to the SilcIDListData structure. It is the
2213 hash negotiated in the SKE protocol. Affected file is
2216 * Slight redesigning of the SilcAuthPayload handling routines.
2217 Do not send SilcPKCS but SilcPublicKey as argument.
2219 * Implemented the public key authentication support to the
2220 serverconfig. The public key is loaded from the provided path
2221 and saved as authentication data to void * pointer. Thus,
2222 changed the unsigned char *auth_data to void *auth_data;
2224 * Fixed SHUTDOWN command to send the reply before the server
2225 is shutdown. :) Affected file silcd/command.c.
2227 * Fixed fatal bug in CONNECT command. The hostname was invalid
2228 memory and server crashed. Affected file silcd/command.c.
2230 * Fixed fatal bug in CLOSE command. The server_entry became
2231 invalid but was referenced later in the command. Affected file
2234 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Fixed fatal bug in failure packet handling. Server ignored
2237 the failure and thus crashed when it came.
2241 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2244 that the command may be executed only once in (about) 2 seconds.
2245 The old SILC_CF_LAG flag is same but allows command bursts up
2246 to five before limiting.
2248 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2249 server code. Various commands now includes the CF_LAG_STRICT
2250 flag to disallow any kind of miss-use of the command.
2252 * Fixed the silc_buffer_unformat to not to allocate any data
2253 if the length of the data is zero. It used to allocate the
2254 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2256 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2258 * Changed the format of AdminConnection configuration section
2259 in the server. Added username of the admin to the format.
2260 Affected files silcd/serverconfig.[ch].
2262 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2263 to return admin configuration data by host, username and/or
2266 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Implemented WHOWAS command to the server. Added the functions:
2270 silc_server_command_whowas_parse,
2271 silc_server_command_whowas_send_reply,
2272 silc_server_command_whowas_from_client and
2273 silc_server_command_whowas_from_server
2275 * Added <Client ID> argument to the WHOWAS command reply. Updated
2276 the protocol specs accordingly.
2278 * Implemented WHOWAS command and command_reply to the client
2281 Implemented the WHOWAS printing on the user interface.
2283 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Added new argument to the WHOWAS command reply, the real name.
2286 It is an optional argument. Updated the protocol specs.
2288 * Added SilcIDCacheDestructor callback that is registered when
2289 the SilcIDCache is allocated. The callback is called when
2290 an cache entry in the ID Cache expires, or is purged from the
2291 cache. Added into lib/silccore/idcache.[ch].
2293 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2294 to destruct the client entries when the cache entry expires.
2295 Other ID Cache's in server and in the client library ignores
2298 * If the ID Cache entry's `expire' field is zero then the entry
2299 never expires. Added boolean `expire' argument to the
2300 silc_idcache_add function in the lib/silccore/idcache.[ch].
2301 If it is TRUE the default expiry value is used.
2303 * Added silc_server_free_client_data_timeout that is registered
2304 when client disconnects. By default for 5 minutes we preserve
2305 the client entry for history - for WHOWAS command.
2307 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Added support to the server to enforce that commands are not
2310 executed more than once in 2 seconds. If server receives
2311 commands from client more frequently, timeout is registered
2312 to process the commands. Affected file silcd/command.c.
2313 Added new function silc_server_command_process_timeout.
2315 * Changed NICK_NOTIFY handling in client library to check that
2316 if the client's nickname was changed, so there is no need to
2317 resolve anything from the server.
2319 * Removed error printing from the WHOIS and IDENTIFY commands.
2320 If error occurs then it is ignored silently in the client library.
2321 The application, however, may map the received error to
2322 human readable error string. The application currently maps
2323 the NO_SUCH_NICKNAME error to string.
2325 * Made the command status message public to the application. Moved
2326 them from lib/silcclient/command_reply.c to
2327 lib/silcclient/command_reply.h. The application can map the
2328 received command status to the string with the
2329 silc_client_command_status_message function.
2331 * Added check to the server to check that client's ID is same
2332 as the Source ID in the packet the client sent. They must
2335 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Added dist-bzip hook to the Makefile.am to make bzip2
2338 compressed distributions.
2340 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Server now enforces the maximum length for the nickname and
2343 the channel as protocol specification dictates. 128 bytes for
2344 nickname and 256 bytes for channel name.
2346 * Moved the WHOIS printing to the application. The client libary
2347 does not print out the WHOIS information anymore, the application
2348 must do it. Renamed silc_client_command_reply_whois_print to
2349 the silc_client_command_reply_whois_save.
2351 The client's idle time is also sent to the application now, and
2352 the idle is shown on screen.
2354 * Added silc_client_command_reply_identify_save to save the
2355 received IDENTIFY entries.
2357 * Do not check for channel private keys in message sending and
2358 reception if the channel does not have the PRIVKEY mode set.
2359 Affected file lib/silclient/client_channel.c.
2361 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2364 just surfaced after chaning the JOIN procedure.
2366 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * Added silc_client_get_clients_by_list to get client entries
2369 from Client ID list, that is returned for example by JOIN
2370 and USERS command replies. The application should use this
2371 function for example when JOIN command reply is received to
2372 resolve the clients already on the channel (library does not
2373 do that anymore as USERS command reply is not used in the JOIN
2374 procedure anymore). Affected files lib/silcclient/silcapi.h and
2375 lib/silcclient/idlist.c.
2377 * JOIN command reply and USERS command reply returns now SilcBuffer
2378 pointers instead of unsigned char pointers when returning
2379 the client list and mode list.
2381 * Added <Client ID> argument to the JOIN command reply, mainly
2382 for the server to identify for which client the command was
2383 originally sent. Updated protocol specs accordingly.
2385 * Added SilcDlist private_key pointer to the SilcChannelEntry
2386 in the client to support the channel private keys. Affected
2387 file is lib/silcclient/idlist.h.
2389 * Added SilcChannelPrivateKey argument to the function
2390 silc_client_send_channel_message so that application can choose
2391 to use specific private ke if it wants to. If it is not provided,
2392 the normal channel key is used, unless private keys are set.
2393 In this case the first (key that was added first) is used
2394 as the encryption key.
2396 * Implemented the support for channel private key handling.
2397 Implemented the following functions:
2399 silc_client_add_channel_private_key,
2400 silc_client_del_channel_private_keys,
2401 silc_client_del_channel_private_key,
2402 silc_client_list_channel_private_keys and
2403 silc_client_free_channel_private_keys
2405 Affected file lib/silcclient/client_channel.c.
2407 * Added the support for the private keys in the channel message
2408 sending and encryption and in the message reception and
2409 decryption. Affected funtions are
2410 silc_client_send_channel_message and silc_client_channel_message.
2412 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Added SKE's key verify callback to the client library's
2415 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2417 * Removed the statement that server (or router) must send USERS
2418 command reply when joining to the channel so that the client
2419 knows who are on the channel. Instead, the client list and
2420 client's mode list is now sent in the JOIN command reply to the
2421 client who joined channel. This is better solution.
2423 * Added function silc_server_get_users_on_channel and function
2424 silc_server_save_users_on_channel to the silcd/server.[ch].
2426 * Removed function silc_server_command_send_users from the
2429 * Do not show topic on the client library anymore. The topic is
2430 sent in the command reply notify to the application and the
2431 application must show the topic now.
2433 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Added client searching by nickname hash into the IDENTIFY and
2436 WHOIS commands in the server as they were clearly missing from
2437 them. Affected file is silcd/command.c.
2439 * Fixed a bug in private message receiving in the client library.
2440 The remote ID was freed and it wasn't supposed, now it is
2443 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Minor fix to the channel payload; allocate the data area, as it
2446 needs to be of specific length.
2448 * If the key agreement port is zero then the operating
2449 system will define the bound port. Affected files are
2450 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2452 * Added new function silc_channel_payload_decrypt into the file
2453 lib/silccore/silcchannel.[ch].
2455 * Moved the channel message etc, check from silc_packet_decrypt
2456 to applications. The library calls now a generic
2457 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2458 when the packet is either normal or special. This was done to
2459 allow more wide range of checking that was not allowed when
2460 the code was in library. Now applications can do virtually any
2461 checks to the packet and return to the library the decision how
2462 the packet should be processed. Affected files are
2463 lib/silccore/silcpacket.[ch].
2465 Added silc_server_packet_decrypt_check to the server and
2466 silc_client_packet_decrypt_check to the client library.
2468 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2469 to send with specified source and destination information.
2471 * Channel message delivery between routers was broken after the
2472 channel key distribution was fixed earlier. The channel key
2473 was used be to distributed to other routers as well which is not
2474 allowed by the protocol. Now this is fixed and channel keys
2475 really are cell specific and the channel message delivery between
2476 routers comply with the protocol specification.
2478 * Fixed various commands in server to check also the global list
2479 for the channel entry and not just the local list. The affected
2480 file silcd/command.c.
2482 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Added assert()s to buffer formatting and unformatting routines
2485 to assert (if --enable-debug) when error occurs. Affected
2486 file: lib/silcutil/silcbuffmt.c.
2488 * Changed to auto-reconnect to check whether the remote host is
2489 router and register the re-connect timeout if it is. It used
2490 to check that whether we are normal server, but router must do
2491 auto-reconnect with another router as well. Affected file
2494 * Removed the [<key len>] option from CMODE command as the cipher
2495 name decides the key length, nowadays. See the defined ciphers
2496 from the protocol specification.
2498 * Added [<hmac>] option to the CMODE command to define the HMAC
2499 for the channel. Added SILC_CMODE_HMAC channel mode.
2501 * Added [<hmac>] option for the JOIN command so that user can
2502 select which HMAC is used to compute the MACs of the channel
2505 * Added Hmac field to the Channel Message Payload. The integrity
2506 of plaintext channel messages are now protected by computing
2507 MAC of the message and attaching the MAC to the payload. The
2508 MAC is encrypted. Now, it is clear that this causes some
2509 overhead to the size of the packet but rationale for this is that
2510 now the receiver can verify whether the channel message decrypted
2511 correctly and also when private keys are set for the channel the
2512 receiver can decrypt the packet with several keys and check from
2513 the MAC which key decrypted the message correctly.
2515 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2516 lib/silccrypt/silccipher.[ch].
2518 * Added silc_hash_len to return the digest length into the
2519 lib/silcrypt/silchash.[ch].
2521 * Rewrote parts of Silc Channel Payload interface in the
2522 lib/silccore/silcchannel.[ch]. The encode function now also
2523 encrypts the packet and parse function decrypts it.
2525 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Fixed a minor formatting bug in the SKE's key material processing.
2528 It actually might have processed the keys wrong way resulting
2531 * Redefined the mandatory HMAC algorithms and added new algorithms.
2532 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2533 and hmac-md5 truncated to 96 bits. The mandatory is now
2534 hmac-sha1-96. Rest are optional (including the one that used
2535 to be mandatory). Rationale for this is that the truncated HMAC
2536 length is sufficient from security point of view and can actually
2537 make the attack against the HMAC harder. Also, the truncated
2538 HMAC causes less overhead to the packets. See the RFC2104 for
2541 * Added new [hmac] configuration section. The SKE used to use
2542 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2543 is of course wrong. The official names that must be proposed in
2544 the SKE are the ones defined in the protocol specification
2545 (hmac-sha1-96 for example). The user can configure any hmac
2546 using any hash function configured in the [hash] section. At
2547 least, the mandatory must be configured.
2549 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2551 * Added HMAC list to the SKE proposal list. It has now both
2552 hash algorithm list and HMAC list. This makes the protocol
2553 incompatible with previous versions. The SKE now seems to work
2554 the way it is supposed to work, for the first time actually.
2556 * Defined plain Hash algorithms to the protocol specification.
2559 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Implemented support for key agreement packets into the server.
2562 Added functions silc_server_key_agreement and
2563 silc_server_send_key_agreement. Other than these functions,
2564 server has nothing to do with this packet.
2566 * Added support for private message key packets into the server.
2567 Added functions silc_server_private_message_key and
2568 silc_server_send_private_message_key.
2572 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2573 called in the protocol's final callback instead in the END
2574 protocol state. This makes a little more sense and in the same
2575 time in client we can use the same protocol routines for normal
2576 key exchange and to key agreement packet handling as well.
2578 * Added to both client's and server's KE protocol context the
2579 SilcSKEKeyMaterial pointer to save the key material. We will
2580 bring the key material to the protocol's final callback by doing
2581 this. The final callback must free the key material.
2583 * Added SKE's packet_send callback into client's KE protocol
2584 context so that the caller can choose what packet sending function
2585 is used. This way we can use different packet sending when
2586 doing normal SKE when doing key agreement packet handling (in
2587 the key agreement packet handling we do not want to encrypt
2590 * Implemented the responder side of the key agreement routines
2591 in the client. The client can now bind to specified port and
2592 accept incoming key negotiation. The key material is passed
2593 to the application after the protocol is over.
2595 * Implemented the processing of incoming Key Agreement packet
2596 in the client. Added function silc_client_key_agreement to
2599 * Implemented the intiator side of the key agreement routines
2600 in the client. The client can now initiate key agreement with
2601 another remote client. The key material is passed to the
2602 application after the protocol is over.
2604 * Created client_keyagr.c to include all the key agreement
2607 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2608 SILC_TASK_CALLBACK except that it is not static.
2610 * Created client_notify.c and moved the Notify packet handling
2611 from the client.[ch] into that file.
2613 * Created client_prvmsg.c and moved all private message and
2614 private message key routines from the client.[ch] into that file.
2616 * Create client_channel.c and moved all channel message and
2617 channel private key routines from the client.[ch] into that file.
2619 * Changed silc_client_get_client_by_id_resolve to resolve with
2620 WHOIS command instead of IDENTIFY command, in the file
2621 lib/silclient/idlist.c.
2623 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Implemented the SKE's responder side to the Client library.
2627 * When FAILURE is received to the protocol do not trust it
2628 blindly. Register a timeout to wait whether the remote closes
2629 the connection as it should do it, only after that process the
2630 actual failure. This was changed to both client and server.
2632 * Added client_internal.h to include some of the structures
2633 there instead of client.h in lib/silcclient/.
2635 * Added function silc_task_unregister_by_callback to unregister
2636 timeouts by the callback function.
2638 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * Some "Incomplete WHOIS info" errors has been appearing on the
2641 log files. Took away the entry->userinfo check from WHOIS
2642 reply sending. The entry->userinfo is now " " if client did not
2643 provide one. I thought this was fixed earlier but something
2644 is wrong still. Let's see if the error still appears.
2646 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Fixed a minor bug in the login when the channel key is
2649 re-generated in the server. It used to generate the key in
2650 wrong order and thus caused problems in the channel traffic.
2652 * Fixed a minor bug in channel key distsribution after
2653 KICK command. The key was not sent to the router even though
2656 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Added silc_ske_process_key_material_data as generic routine
2659 to process any key material as the SILC protocol dictates. The
2660 function is used by the actual SKE library but can be used by
2661 applications as well. This relates to the private message keys
2662 and the channel private keys since they must be processed the
2663 same way the normal SILC session keys. The protocol dictates
2664 this. Affected files: lib/silcske/silcske.[ch].
2666 Added also silc_ske_free_key_material to free the
2667 SilcSKEKeyMaterial structure.
2669 * Defined silc_cipher_set_key function to set the key for
2670 cipher without using the object's method function. The affected
2671 files: lib/silccrypt/silccipher.[ch].
2673 * Implemented silc silc_client_add_private_message_key,
2674 silc_client_add_private_message_key_ske,
2675 silc_client_del_private_message_key,
2676 silc_client_list_private_message_keys and
2677 silc_client_free_private_message_keys functions in the
2680 Added functions silc_client_send_private_message_key to send
2681 the Private Message Key payload and silc_client_private_message_key
2682 to handle incoming Private Message Key payload.
2684 * Added Cipher field to the Private Message Key payload to set
2685 the cipher to be used. If ignored, the default cipher defined
2686 in the SILC protocol (aes-256-cbc) is used.
2688 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Removed lib/silcclient/ops.h file.
2692 Redefined parts of the SILC Client Library API. Created new
2693 file silcapi.h that deprecates the ops.h file and defines the
2694 published Client Library API. Defined also private message key
2695 API and channel private key API into the file.
2697 This is the file that the application must include from the
2698 SILC Client Library. Other files need not be included by
2699 the application anymore.
2701 * Added new key_agreement client operation callback and also
2702 defined the Key Agreement library API for the application.
2704 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2707 is used by clients to request key negotiation between another
2708 client in the SILC network. If the negotiation is started it
2709 is performed using the SKE protocol. The result of the
2710 negotiation, the secret key material, can be used for example
2711 as private message key.
2713 Implemented the Key Agreement payload into the files
2714 lib/silccore/silauth.[ch].
2716 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2718 * Redefined ciphers for the SILC protocol. Added some new ciphers
2719 and defined the key lengths for the algorithms. Changed the
2720 code accordingly. The default key length is now 256 bits.
2722 * Fixed SKE key distribution function silc_ske_process_key_material
2723 when the key length is more than 128 bits. The default key
2724 length in SILC is now 256 bits.
2726 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2727 to indicate unsupported algorithm.
2729 * Renamed rijndael.c to aes.c and all functions as well.
2731 * Fixed a long standing channel key setting bug in client library.
2732 Weird that it has never surfaced before.
2734 * Fixed bug in channel deletion. If the entire channel is removed
2735 then it must also delete the references of the channel entry
2736 from the client's channel list as the client's channel entry and
2737 the channel's client entry share same memory.
2739 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Implemented CONNECT and SHUTDOWN commands in the client.
2743 * Implemented CLOSE command to the client.
2745 * Added the function silc_idlist_find_server_by_name into the
2746 files silcd/idlist.[ch].
2748 Added the function silc_idlist_find_server_by_conn into the
2749 files silcd/idlist.[ch].
2751 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * DIE command was renamed to SHUTDOWN. Updated the both code
2756 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2757 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2759 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2762 * Added function silc_server_create_connection function to create
2763 connection to remote router. My server implementation actually
2764 does not allow router to connect to normal server (it expects
2765 that normal server always initiates the connection to the router)
2766 so the CONNECT command is only good for connecting to another
2769 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2772 or some other client was kicked from the channel.
2774 Implemented the handling of the notify type to both client
2777 Implemented silc_server_send_notify_kicked to send the KICKED
2778 notify. It is used to send it to the server's primary router.
2780 * Implemented the KICK command into server and client.
2782 * Added `query' argument to the silc_idlist_get_client function
2783 to indicate whether to query the client from server or not if
2786 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2787 to indicate that the client is not channel founder.
2791 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Removed the rng context from SilcPacketContext structure and
2794 changed that the packet routine uses the Global RNG API.
2796 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Added support for quit message that client can "leave" on the
2799 channel when it quits the SILC. It is ditributed inside the
2800 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2802 Added silc_server_free_client_data that will take the
2803 signoff message as argument.
2805 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2807 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Updated parts of the protocol specification to keep it up
2812 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2815 payloads in one packet.
2817 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2818 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2819 use now the new List flag.
2821 * Also deprecated the following packet types: REPLACE_ID,
2822 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2824 * Added list support for Notify packet in server.
2826 * Added silc_server_send_notify_channel_change to send the
2827 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2828 the silc_server_send_replace_id.
2830 * Added silc_server_send_notify_nick_change to send the
2831 NICK_CHANGE notify type. Deprecates the function
2832 silc_server_send_replace_id.
2834 * Added silc_server_send_notify_join to send the JOIN notify type.
2835 Deprecates the function silc_server_send_new_channel_user.
2837 * Added silc_server_send_notify_leave to send LEAVE notify type.
2838 Deprecates the function silc_server_send_remove_channel_user.
2840 * Added silc_server_send_notify_cmode and
2841 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2842 types. Deprecates the silc_server_send_set_mode function.
2844 * Added SERVER_SIGNOFF notify type to indicate that server has
2845 quit. This means that all clients on the channel from that
2846 server will drop. This can be also used when netsplit happens.
2848 Deprecated REMOVE_ID packet type since it is not needed anymore
2851 Added silc_server_send_notify_server_signoff to send the
2852 SERVER_SIGNOFF notify type. Deprecates the function
2853 silc_server_send_remove_id.
2855 Added also silc_server_send_notify_signoff to send the
2856 SIGNOFF notify type.
2858 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2859 SILC protocol from this day on. Changed the protocol
2860 specification as well.
2862 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2863 notify type. It is used between routers to notify about
2864 topic changes on a channel.
2866 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2869 * Partly updated the protocol specification to comply with the
2870 changes now made. It is still though a bit outdated.
2872 * The JOIN notify type now takes one extra argument <Channel ID>.
2873 The packet used to be destined to the channel but now the
2874 JOIN type may be sent as list thus it is impossible to
2875 destine it to any specific channel. By adding this argument
2876 it is again possible.
2878 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Added CREDITS file. The CHANGES and CREDITS file will appear
2881 in the distribution as well.
2883 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2886 types in the server's silcd/packet_receive.c.
2888 * Implemented CMODE and CUMODE to work in router environment.
2890 * Fixed minor encoding and decoding buglet from the
2891 lib/silccore/silcmode.c.
2893 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2896 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2898 * Changed all SilcConfigServer* and silc_config_server* to
2899 SilcServerConfig* and silc_server_config*, respectively.
2902 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Associated the ID (client or server ID) to the Authentication
2905 Payload to avoid any possibility of forging. Updated the
2906 protocol specification and the code accordingly.
2908 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * The RSA key length is now save to the RsaKey context in the
2911 key generation process in lib/silccrypt/rsa.c. The key length
2912 is now used to figure out the maximum size of the block allowed
2913 to be encrypted/signed.
2915 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2916 is equivalent to the silc_mp_mp2bin but does not allocate any
2919 * Changed silc_mp_mp2bin API to take length argument. If it is
2920 non-zero then the buffer is allocated that large. If zero, then
2921 the size is approximated using silc_mp_sizeinbase, which however
2924 * Created Global RNG API which is global RNG that application can
2925 initialize. After initializing, any routine anywhere in the
2926 code (including library) can use RNG without allocating a new
2927 RNG object. This was done to allow this sort of use of the
2928 RNG in code that has no chance to allocate RNG object. All
2929 applications currently allocate this and many routines in the
2930 library use this. Affected file lib/silccrypt/silcrng.[ch].
2932 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2933 it to use the Global RNG API.
2935 * Defined Authentication Payload into protocol specification that
2936 is used during SILC session to authenticate entities. It is
2937 used for example by client to authenticate itself to the server
2938 to obtain server operator privileges.
2940 Implemented this payload into the lib/silccore/silcauth.[ch].
2941 Implemented also routines for public key based authentication
2942 as the new protocol specification dictates.
2944 Moved definitions of different authentication methods from
2945 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2947 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2948 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2949 silc_pkcs_verify_with_hash functions into the file
2950 lib/silccrypt/silcpkcs.[ch].
2952 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * The client entry's userinfo pointer must be always valid.
2955 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2956 will fail since it requires the userinfo. Now, the userinfo
2957 is allocated as "" if actual userinfo does not exist. Actually,
2958 it must exist and it is totally Ok to drop client connections
2959 that does not announce the userinfo. However, we will make
2960 this workaround for now.
2962 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2963 to return the remote port by socket.
2965 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2968 SILC_SERVER_PENDING_EXEC and added an new macro
2969 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2970 data or when error occurs while processing the pending command.
2972 Added new argument `destructor' into silc_server_command_pending
2973 and to the SilcServerCommandPending object. This destructor is
2974 now called after calling the pending callback or if error occurs
2975 immediately. If error occurs the actual pending callback won't
2976 be called at all - only the destructor. The destructor may be
2977 NULL if destructor is not needed.
2979 All this applies for client library code as well. Similar
2980 changes were made there as well for the pending commands.
2982 In the client, the application must now allocate the
2983 SilcClientCommandContext with the silc_client_command_alloc
2986 * Added reference counter to the SilcServerCommandContext. Added
2987 function silc_server_command_alloc and silc_server_command_dup
2990 Same type of functions added to the client library for the same
2993 * Removed the cmd_ident from IDListData away since it is now
2994 global for all connections. It is the command identifier used
2995 in command sending and with pending commands. The affected file
2998 * Added reference counter to the SilcSocketConnection objecet to
2999 indicate the usage count of the object. The object won't be
3000 freed untill the reference counter hits zero. Currently only
3001 server uses this, and client ignores it. The client must be
3002 set to use this too later. The affected files are
3003 lib/silccore/silcsockconn.[ch]. Added also the function
3004 silc_socket_dup to increase the reference counter.
3006 This was mainly added because it is possible that the socket
3007 is removed underneath of pending command or other async
3008 operation. Now it won't be free'd and proper DISCONNECTING
3009 flags, etc. can be set to avoid sending data to connection that
3010 is not valid anymore.
3012 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3013 the connection. After that it sets SILC_SET_DISCONNECTED.
3014 It is, however, possible that the socket data is not still freed.
3015 The silc_server_packet_process now checks that data is not
3016 read or written to connection that is DISCONNECTED. The socket
3017 get's freed when the reference counter hits zero.
3019 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Changed the client operation API: channel_message operation's
3022 `sender' is now the client entry of the sender, not the nickname
3023 and the `channel' is the channel entry, not the channel name.
3025 In the private_message operation the `sender' is now also the
3026 client entry of the sender not the nickname.
3028 Affected file is lib/silcclient/ops.h and all applications
3029 using the client operations.
3031 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Moved the calling of ops->connect() from connect_to_server_final
3034 into receive_new_id functin since that is the point when the
3035 client is actually allowed to send traffic to network. The
3036 affected file is lib/silcclient/client.c.
3038 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3041 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3042 (if needs broadcasting) instead of broadcasting the packets one
3043 by one which would make a burst in the network traffic.
3045 * Added `broadcast' argument to the functions in silcd/server.[ch]
3046 silc_server_create_new_channel[_with_id] to indicate whether
3047 to send New Channel packet to primary router.
3049 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Added new function into the silcd/server.[ch] files:
3052 silc_server_create_new_channel_with_id to create new channel with
3053 already existing Channel ID.
3055 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3056 lib/silccore/silcpacket.h. This packet is used t send list of
3057 Set Mode payloads inside one packet. Server uses this to set
3058 the modes for the channels and clients on those channels, that it
3059 announced to the router when it connected to it. The protocol
3060 specification has been updated accordingly.
3062 * The silc_server_new_channel did not handle the packet coming
3063 from normal server as it normally does not send that. However,
3064 when it announces its channels it does send it. Implemented
3065 the support for that.
3067 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3068 into the file lib/silccore/id.h.
3070 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Fixed memory leaks in the functions silc_idlist_del_client,
3073 silc_idlist_del_channel and silc_idlist_del_server in the file
3074 silcd/idlist.c. All of those leaked like a sieve.
3076 * Fixed some small memory leaks in the client's function
3077 silc_client_notify_by_server.
3079 * Added functions into silcd/server.c: silc_server_announce_clients,
3080 silc_server_announce_channels and silc_server_announce_server.
3081 These functions are used by normal and router server to announce
3082 to its primary router about clients, channels and servers (when
3083 router) that we own. This is done after we've connected to the
3086 These functions effectively implements the following packet types:
3087 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3088 and SILC_PACKET_NEW_ID_LIST.
3090 * Added new functions into the silcd/packet_receive.[ch]:
3091 silc_server_new_id_list, silc_server_new_channel_list and
3092 silc_server_new_channel_user_list to handle the incoming
3093 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3095 * Added support of changing Channel ID in the function
3096 silc_server_replace_id. If the server that announces a channel
3097 to the router already exists in the router (with same name but
3098 with different Channel ID), router is responsible to send
3099 Replace ID packet to the server and force the server to change
3100 the Channel ID to the one router has.
3102 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3103 client that the Channel ID has been changed by the router. The
3104 normal server sends this to the client. Client must start using
3105 the new Channel ID as the channel's ID.
3107 Implemented handling of this new type into lib/silcclient/client.c
3108 into the function silc_client_notify_by_server.
3110 * Added new function silc_idlist_replace_channel_id into the files
3111 silcd/idlist.[ch] to replace the Channel ID.
3113 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Call silc_server_command_identify_check always when processing
3116 the IDENTIFY command in silcd/command.c
3118 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3121 send keepalive packets. The packet can be sent by clients,
3122 servers and routers.
3124 Added function silc_socket_set_heartbeat into the file
3125 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3126 If not set, the heartbeat is not performed. The actual
3127 heartbeat is implemented in the low level socket connection
3128 library. However, application is responsible of actually
3131 Added silc_server_send_heartbeat to send the actual heartbeat
3132 packet into silcd/packet_send.[ch]. Server now performs
3133 keepalive with all connections.
3135 * Added silc_task_get_first function into lib/silcutil/silctask.c
3136 to return the timeout task with shortest timeout. There was a bug
3137 in task unregistration that caused problems. TODO has been
3138 updated to include that task system must be rewritten.
3140 * The client library will now resolve the client information when
3141 receiving JOIN notify from server for client that we know but
3142 have incomplete information.
3144 * Rewrote parts of silc_server_remove_from_channels and
3145 silc_server_remove_from_one_channel as they did not remove the
3146 channel in some circumstances even though they should've.
3148 * Encryption problem encountered in server:
3150 The LEAVE command used to send the Channel Key packet to the
3151 router immediately after generating it. However, the code
3152 had earlier sent Remove Channel user packet but not immediately,
3153 ie. it was put to queue. The order of packets in the router
3154 was that Channel Key packet was first and Remove Channel User
3155 packet was second, even though they were encrypted in the
3156 reverse order. For this reason, MAC check failed. Now, this
3157 is fixed by not sending the Channel Key packet immediately but
3158 putting it to queue. However, this is more fundamental problem:
3159 packets that are in queue should actually not be encrypted
3160 because packets that are sent immediately gets encrypted
3161 actually with wrong IV (and thus MAC check fails). So, packets
3162 that are in queue should be encrypted when they are sent to
3163 the wire and not when they put to the queue.
3165 However, the problem is that the current system has not been
3166 designed to work that way. Instead, the packet is encrypted
3167 as soon as possible and left to the queue. The queue is then
3168 just purged into wire. There won't be any fixes for this
3169 any time soon. So, the current semantic for packet sending
3172 o If you send packet to remote host and do not force the send
3173 (the packet will be in queue) then all subsequent packets to the
3174 same remote host must also be put to the queue. Only after the
3175 queue has been purged is it safe again to force the packet
3178 o If you send all packets immediately then it safe to send
3179 any of subsequent packets through the queue, however, after
3180 the first packet is put to queue then any subsequent packets
3181 must also be put to the queue.
3183 Follow these rules and everything works fine.
3185 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Added new function silc_server_remove_clients_by_server to
3188 remove all client entries from ID list when the server connection
3189 is lost. In this case it is also important to invalidate all
3190 client entires as they hold the invalid server entry. This
3191 fixes fatal bug when server has lost connection and will reconnect
3194 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Made some sanity checks to silc_server_daemonise like to check
3197 whether the requested user and group actually exists.
3199 * Added sanity check to SKE's silc_ske_responder_finish to check
3200 that the public and private key actually is valid.
3202 * Invalidate the client's nickname when receiving Replace ID
3203 packet and the Client ID is being replaced. This means that the
3204 server will query the nickname if someone needs it (client)
3207 * Sort the ID Cache in client library when the ID Cache data
3208 has changed (needs sorting).
3210 * Do not allow for SILC client to create several connections to
3211 several servers. The client does not support windows right now
3212 and generating multiple connections causes weird behaviour.
3214 Irssi-silc client does support windows and can handle several
3215 connections without problems, see: www.irssi.org and SILC plugin.
3217 * Fixed some places where client was added to the IDList. The
3218 rule of thumb is following (in order to get everything right):
3219 If the client is directly connected local client then the
3220 `connection' argument must be set and `router' argument must be
3221 NULL to silc_idlist_add_client function. If the client is not
3222 directly connected client then the `router' argument must
3223 bet set and the `connection' argument must be NULL to the
3224 silc_idlist_add_client function.
3226 * The funtion silc_server_packet_send_local_channel actually did
3227 not check whether the client was locally connected or not. It
3228 does that now. Fixed a bug related to LEAVE command.
3230 * Fixed Remove Channel User payload parsing bug in server's
3231 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3233 * The server's silc_server_save_channel_key now checks also the
3234 global ID list for the channel as it might not be in the local
3235 list. Fixed a bug related to LEAVE command.
3237 * Is this the end of the [<unknown>] buglet that has been lurking
3238 around for a long time? A little for loop fix in server's
3239 silc_server_command_whois_parse that is used by both IDENTIFY
3240 and WHOIS command. At least, this was a clear bug and a cause
3241 of one type of [<unknown>] buglet.
3243 * WHOIS and IDENTIFY commands call the function
3244 silc_server_command_[whois/identify]_check function even if
3245 we are not router server.
3247 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added --with-gmp configuration option. If set the GMP
3250 is always compiled in the SILC source tree. If not set then
3251 it is checked whether the system has the GMP3 installed. If
3252 it has then the GMP won't be compiled (the system's headers
3253 and library is used), if it doesn't have it then the GMP is
3254 compiled in the SILC source tree.
3256 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Changed RSA private exponent generation to what PKCS #1
3259 suggests. We try to find the smallest possible d by doing
3260 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3261 not security fix but optimization.
3263 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Added new config entry [Identity] to fork the server and run
3266 it as specific user and group. A patch from Bostik.
3268 * Imported Dotconf configuration library into lib/dotconf.
3269 This will be used to create the SILC configuration files later.
3270 It will appear in the distsribution after this commit.
3272 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * A big code auditing weekend happening. Auditing code for
3275 obvious mistakes, bugs and errors. Also, removing any code
3278 Removed files for being obsolete:
3280 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3281 inline in the file lib/silcutil/silcbuffer.h)
3283 o lib/silcutil/silcbufutil.c (the header has inline versions)
3285 Changed code to fix possible error conditions:
3287 o The buffer formatting routines now check that the destination
3288 buffer really has enough space to add the data. This applies for
3289 both buffer formatting and unformatting
3290 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3291 unformatting was changed to accomodate following rules:
3292 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3293 sent to the function while XXX_*STRING will not allocate or copy
3294 the data into the buffer. Instead it sets the pointer from the
3295 buffer into the pointer sent as argument (XXX_*STRING used to
3296 require that the pointer must be allocated already). This change
3297 makes this whole thing a bit more consistent and more optimized
3298 (note that the data returned in the unformatting with XXX_*STRING
3299 must not be freed now). The routines return now -1 on error.
3301 o Tried to find all code that use buffer_format and buffer_unformat
3302 and added return value checking to prevent formatting and
3303 especially unformatting errors and possible subsequent fatal
3306 o Changed ske->x and ske->KEY to mallocated pointers in
3307 lib/silcske/silcske.h. Fixed possible data and memory leak.
3309 o Added return value checking to all *_parse* functions. Fixed
3310 many memory leaks as well.
3312 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3313 so that buffer overflows would not happen. All code now also
3314 checks the return value as it can fail.
3316 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Added reconnection support to server if the normal server looses
3319 its connection to the router (for example if router is rebooted).
3320 The server performs normal reconnection strategy implemented
3321 to the server. Affected file silcd/server.c.
3323 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Added new packet type SILC_PACKET_SET_MODE that is used to
3326 distribute the information about changed modes (for clients,
3327 channels and clients channel modes) to all routers in the
3328 network. Updated the protocol specification accordingly.
3330 Added functions into silcd/packet_send.c and
3331 silcd/packet_receive.c: silc_server_send_set_mode,
3332 silc_server_set_mode.
3334 Added new files silcmode.[ch] into lib/silccore that implements
3335 the encoding and decoding of Set Mode Payload. Added new type
3336 SilcSetModePayload. Moved the definitions of different modes
3337 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3339 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Oops, a little mistake in server's connection authentication
3342 protocol. The protocol is not ended with FAILURE but with
3343 SUCCESS if the authentication is Ok. :) Affected file is
3346 * Implemented NICK_CHANGE notify handling in server in the file
3347 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3348 the local clients on the channel. After the changing nickname
3349 in router environment snhould work and the [<unknown>] nickname
3350 should appear no more.
3352 The silc_server_replace_id function that receives the Replace ID
3353 payload now sends the NICK_CHANGE notify type also in the file
3354 silcd/packet_receive.c
3356 * Changed WHOIS and IDENTIFY command to support the maximum amount
3357 of arguments defined in protocol specs (3328 arguments). This
3358 fixed a bug that caused problems when there were more than three
3361 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Added extra parameter, command identifier, to the
3364 silc_client_send_command so that explicit command identifier
3367 Changed that ID list routines uses specific command identifier
3368 when sending WHOIS/IDENTIFY requests to the server so that they
3369 can be identified when the reply comes back.
3371 Affected files lib/silcclient/command.[ch],
3372 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3374 * Added `sender' argument to silc_server_packet_send_to_channel
3375 to indicaet the sender who originally sent the packet to us
3376 that we are now re-sending. Ignored if NULL. Affected file
3377 silcd/packet_send.[ch].
3379 * Added some server statistics support in silcd/server_internal.h
3380 SilcServerStatistics structure and around the server code. Also
3381 send some nice statistics information when client is connecting
3384 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Fixed channel ID decoding in server's JOIN command reply in
3387 silcd/command_reply.c
3389 * Fixed braodcasting of replace ID payload to not to send it if
3390 we are standalone server in silcd/packet_receive.c.
3392 * Fixed all channel message sending routines to not to send
3393 packets to clients that has router set, since they are routed
3394 separately in the same function earlier. Affects file
3395 silcd/packet_send.c and all channel packet sending functions.
3397 * In USERS reply, res_argv[i] are not allocated, the table
3398 is allocated. Thus changed that free the table, not its
3401 * In server's whois_check and identify_check if the client is
3402 locally connected do not send any WHOIS commands - they are not
3405 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Fixed some minor bugs in client when sending WHOIS command. The
3408 arguments was in wrong order.
3410 * Removed statis function add_to_channel from server in
3411 silcd/command.c that was previously used with the joining but
3414 * Tested USERS command in router environment successfully with two
3415 routers, two servers and two clients.
3417 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Reorganized the USERS command and command reply in client library
3420 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3421 When the command is given by user we register a pending command
3422 callback that will reprocess the command after the reply has been
3423 received from the server. When reprocessing the packet we then
3424 display the information. Thus, the USERS information is displayed
3425 now in the command callback instead of in the command reply
3426 callback. The processing of the command is same as previously
3427 when server has sent the command reply in the JOINing process.
3429 * Added to USERS command in silcd/command_reply.c to join the client,
3430 we didn't use to know about, to the channel after we've created
3431 a client entry for it. Also, for clienet we did know already still
3432 check whether it is on the channel or not and add it if not.
3434 * Removed silc_server_command_join_notify as the function and its
3437 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Changed the client's pending command handling to the same as the
3440 server's pending command handling. It is also now possible to
3441 execute command reply functions from other command reply
3442 function as the function callbacks for commands and command
3443 replies are one and same. The pending commands are not static
3444 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3445 in client connection context. Thus, pending commands are server
3446 connection specific as it is convenient.
3448 Changed the function silc_client_command_pending and
3449 silc_client_command_pending_del and added new function
3450 silc_client_command_pending_check. Removed the
3451 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3454 * Added cmd_ident, current command identifier, to the client
3455 connection context in lib/silcclient/client.h to keep track on
3456 command identifiers used in command sending. Client's command reply
3457 function handling now supports the mandatory command identifiers.
3459 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3460 funtions in client to fully support pending command callbacks.
3462 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3463 as one of the arguments to the application in the command reply
3466 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3467 before first releasing SILC but came back. Now it is removed again
3468 and should come back nomore. The FORWARDED flag was used only
3469 by the JOINing procedure by forwarding the command packet to router.
3470 Now, the JOINing procedure has been changed to more generic (due
3471 to various router environment issues) and FORWARDED is not needed
3472 anymore for anything. The protocol specification is yet to be
3475 Now, removed silc_server_packet_forward from server and the flag
3476 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3478 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Renamed NAMES command to USERS command. The NAMES was named that
3481 due to historical reasons. Now it is renamed. Also, rewrote
3482 parts of the USERS command. The nickname list is not sent anymore
3483 by the server. Only Client ID and mode lists are sent in the USERS
3484 command. Changed this also to the protocol specification.
3486 The client now resolves the names and stuff after it receives
3487 the USERS list from the server when joining to the channel.
3489 * WHOIS and IDENTIFY commands has been changed to support multiple
3490 Client ID's per command. One can now search for multiple users
3491 in the network by sending only one WHOIS or IDENTIFY command.
3492 Changed the code and the protocol specifications.
3494 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3495 uses silc_server_command_whois_parse to parse the request. */
3497 * If normal server, do not parse the WHOIS and IDENTIFY requests
3498 before sending it to the router. Saves some time.
3500 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Fixed JOIN command on client library. Wrong number of arguments
3503 used to crash the client.
3505 * Added silc_server_channel_has_global function to check whether
3506 channel has global users or not.
3508 * Added silc_server_channel_has_local function to check whether channel
3509 has locally connected clients on the channel.
3511 * The silc_server_remove_from_one_channel now checks whether the
3512 channel has global users or not after given client was removed from
3513 the channel. It also checks whether the channel has local clients
3514 on the channel anymore. If it does not have then the channel entry
3515 is removed as it is not needed anymore.
3517 * The silc_server_notify now checks on JOIN notify whether the joining
3518 client is one of locally connected or global. If it is global then
3519 the channel has now global users on the channel and that is marked
3520 to the channel entry. Also, it now saves the global client to
3521 global list who is joining and JOINs it to the channel. This is
3522 for normal server, that is.
3524 Changed silc_server_send_notify_on_channel,
3525 silc_server_packet_relay_to_channel and
3526 silc_server_packet_send_to_channel check if we are normal server
3527 and client has router set (ie. global client) do not send the
3528 message to that client, as it is already routed to our router.
3530 * Implemented LEAVE notify type handling in silc_server_notify
3533 * Tested LEAVE command in router environment successfully. Tested
3534 with two routers, two servers and two clients.
3538 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3540 * Implemented SIGNOFF notify type handling in silc_server_notify
3543 * silc_server_remove_id now removes the client entry from all channels
3544 it has joined and thusly sends SIGNOFF notify type.
3546 * Rewrote the NAMES list generation in server by removing two excess
3547 loops. The lists are created now inside one loop.
3549 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * silc_server_remove_channel_user checks now also global list
3552 for channel and client.
3554 * silc_server_new_channel_user checks now both local and global
3555 list for channel and client. Fixed a bug in client id decoding.
3556 Used to decode wrong buffer.
3558 * silc_server_channel_message checks now both local and global
3559 list for channel entry.
3561 * Tested channel joining (hence JOIN) in router environment
3562 successfully. Tested with two routers, two servers and two
3565 * Tested channel message sending in router environment successfully.
3567 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Added silc_server_save_channel_key into server.[ch] to save the
3570 received channel key in Channel Key payload processing. It is
3571 also used in JOIN command reply handling.
3573 Equivalent function silc_client_save_channel_key added into
3574 client.[ch] into client library.
3576 * Changed JOIN command reply to send information whether the channel
3577 was created or not (is existing already) and the channel key
3578 payload. Changed protocol specs accordingly.
3580 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3581 the request was sent by ID and not by nickname. Crashed on
3584 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3587 now correctly save the received data.
3589 * silc_server_free_sock_user_data now notifies routers in the
3590 network about entities leaving the network.
3592 At the same time implemented functions silc_server_remove_id
3593 and silc_server_send_remove_id to receive and send REMOVE_ID
3594 packets. The packet is used to notify routers in the network
3595 about leaving entities. The ID removed will become invalid in
3598 * Added function silc_idlist_del_server into server. Removes and
3599 free's server entry from ID list.
3601 * silc_server_private_message function now checks, if we are router,
3602 that the destination ID really is valid ID, naturally.
3604 * In router when NEW_ID packet is received (for new client) the
3605 hash of the Client ID is saved in the ID Cache but the
3606 client->nickname is set to NULL, instead of putting the hash
3609 IDENTIFY command now also checks that client->nickname must be
3610 valid. If it is not if will request the data from the server who
3611 owns the client. Added new function
3612 silc_server_command_identify_check.
3614 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3615 to set the command to already allocated Command Payload.
3617 * Tested private message sending in router environment with two
3618 routers, two servers and two clients. Fixed minor bugs and now
3621 * Fixed segfault from client's NAMES command. Used to crash if
3624 * Forwarded packets must not be routed even if it is not destined
3625 to the receiver. Changed server code comply with this.
3627 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Added `require_reverse_mapping' boolean value to ServerParams
3630 structure. If TRUE (not default) the server will require that
3631 the connecting host has fully qualified domain name.
3633 If the reverse mapping is not required and hostname could not be
3634 found the IP address is used as hostname.
3636 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Implemented version string checking to both client and server.
3639 The check is incomplete currently due to the abnormal version
3640 strings used in development version of SILC.
3642 * Changed all command functions in server to use the new
3645 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Changed char *data to unsigned char *data in ID Cache system to
3648 support binary data as ID Cache data. Changed code to support
3649 binary data in lib/silccore/idcache.c.
3651 * Renamed silc_server_packet_relay_command_reply to
3652 silc_server_command_reply as it is normal packet receiving
3653 function. Rewrote the function to accept command replys for
3654 servers and not only for clients.
3656 * Mark remote router always as registered server if we are connecting
3657 to it. Otherwise, commands sent by the router to us are ignored.
3659 * All ID List find routines now returns the ID Cache Entry pointer
3660 as well if requested.
3662 * WHOIS command works now in router environment, tested with two
3663 routers, two servers and two clients.
3665 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3666 in router environment (as it is almost equivalent to WHOIS) but
3667 hasn't been tested thoroughly. Added new functions:
3669 silc_server_command_identify_parse
3670 silc_server_command_identify_send_reply
3671 silc_server_command_identify_from_client
3672 silc_server_command_identify_from_server
3674 * Disabled route cache adding because adding two different ID's with
3675 same IP replaces the old cache entry thus giving wrong route.
3676 The entry->router->connection is always the fastest route anyway
3677 so route cache may not be needed. Of course, new routes maybe
3678 established after receiving the ID when the entry->router->connection
3679 might not be anymore the most optimal.
3681 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Add route cache for received ID for fast routing.
3685 * Added silc_server_packet_route to route received packet on router
3686 that is not destined to us.
3688 * Renamed silc_server_get_route to silc_server_route_get.
3690 * Added id_string and id_string_len fields into SilcServer to
3691 include encoded ServerID for fast comparing without excess
3692 encoding of the ID's.
3694 * Cleaned up WHOIS command on server side. Added following static
3697 silc_server_command_whois_parse
3698 silc_server_command_whois_check
3699 silc_server_command_whois_send_reply
3700 silc_server_command_whois_from_client
3701 silc_server_command_whois_from_server
3703 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3704 arguments in command replies. All command functions should be
3705 updated to use this macro.
3707 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Minor typo fixes on command reply handling on server.
3711 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Added silc_server_command_add_to_channel internal routine to add
3714 the client to the channel after router has created the channel and
3715 sent command reply to the server.
3717 * Added generic silc_server_send_command to send any command from
3720 * Use static buffer with ID rendering instead of duplicating data.
3722 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Fixed a channel user mode bug when joining to a channel server gave
3725 everybody channel founder rights, oops.
3727 * We mark ourselves as the router of the incoming server connection
3728 if we are router ourselves. This way we can check in some packet
3729 sending functions whether it is locally connected server. For
3730 incoming router connections we put NULL.
3732 * For router sending packets locally means now always sending the
3733 packet cell wide; to local clients and local servers. For normal
3734 server sending packet locally means sending it to only local
3737 * Fixed the JOIN command to really work in router environment. If the
3738 channel is created it is always created by the router. Router is
3739 also responsible of making the initial joining to the channel,
3740 sending JOIN notify to the sending server and distributing
3741 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3742 does not exist server doesn't do anything else but forward the
3743 command to the router which performs everything.
3745 * Added silc_server_send_channel_key function to send the Channel Key
3748 * Added silc_server_create_channel_key to create new channel key. The
3749 channel key is now re-generated everytime someone joins or leaves
3750 a channel, as protocol dictates. Note: channel->key_len is the
3753 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3756 packet_receive.[ch] to separate packet sending and receiving
3757 routines. The server.[ch] now includes everything else including
3758 actual packet processing (writing and reading data) and other
3761 Renamed silc_server_private_message_send_internal to
3762 silc_server_send_private_message. The routine is still though
3763 used only to relay private messages as server does not send
3764 private messages itself.
3766 Renamed silc_server_new_channel to silc_server_create_new_channel
3767 and added new function sicl_server_new_channel that handles the
3768 incoming New Channel packet. Added also new sending function
3769 silc_server_send_new_channel to send New Channel Payload.
3771 * Added new function silc_server_notify to process incoming notify
3772 packet to the server/router. Server may then relay the notify
3773 to clients if needed.
3775 * Added new function silc_server_new_channel_user to process incoming
3776 New Channel User packet. Router will redistribute the packet and
3777 send JOIN notify to its local clients and locally connected servers
3778 if needed. Normal server will send JOIN notify to its local client
3779 on same channel when received this packet. Added also corresponding
3780 sending function silc_server_send_new_channel_user to sent the
3783 * Added boolean route argument to send_notif_to_channel and
3784 packet_send_to_channel functions to attempt to route the packet
3785 if it is TRUE and send only locally if it is FALSE.
3787 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * silc_server_replace_id now broadcasts the received replace ID
3790 packet if it is not broadcast packet already. The router must
3791 broadcast to inform other routers about changed ID.
3793 * Added backpointer to server's router into SilcServer context in
3794 silcd/server_internal.h.
3796 * Fixed silc_server_packet_broadcast to send correct broadcast
3799 * The channel key is now distributed to the local client as soon
3800 as it is received from the router (in router environment) so that
3801 no other packet may be sent for the channel until client has
3804 * silc_server_remove_channel_user now broadcasts the received
3805 Remove Channel User packet if it is not broadcast packet already.
3806 The router must broadcast to inform other routers about removed
3809 * Added users field into SilcPacketContext that is a reference count
3810 of the context. One can increase the reference count by calling
3811 silc_packet_context_dup which is now changed to just increase the
3812 reference count instead of duplicating the data. The reference
3813 count is decresed by calling silc_packet_context_free that will
3814 free the data after the reference count hits zero.
3816 For now on the packet context and everything allocated into it
3817 (including the raw packet from network) must be freed by calling
3818 the new silc_packet_context_free function. Added also new function
3819 silc_packet_context_alloc that must be used now to allocate the
3820 context. This also means that if a routine is asynchronous from
3821 silc_[client/server]_packet_parse_type the packet context must
3822 be duplicated by calling silc_packet_context_dup. Otherwise it
3823 gets free'd after silc_[client/server]_packet_parse_type returns.
3824 Also, one must remember that if packet is duplicated then its
3825 reference count must be decresed by calling the free function as
3826 many times as it was duplicated.
3828 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3829 from both client and server.
3831 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Made joining to a channel working in router environment.
3835 * Cleaned up JOIN command on server side and create function
3836 silc_server_command_join_channel internal routine to make the
3839 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Changed silc_command_pending list to SilcDList. Also, added
3842 `ident' field to SilcServerCommandPending structure to identify
3843 the reply and to call correct callback.
3845 Added silc_server_command_pending_check function to replace the
3846 corresnponding macro. The silc_command_pending list is not
3849 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3850 to set identifier to previously allocated Command Payload. It
3851 is used to set identifier for command when resending Command
3854 * Added silc_command_payload_encode_payload to encode Command
3855 Payload buffer from SilcCommandPayload structure.
3857 * Added silc_argument_payload_encode_payload to encode Argument
3858 payload buffer from SilcArgumentPayload structure.
3860 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Changed WHOIS command to support router connection on server side.
3863 The whois request is always sent to router unless the server is
3864 standalone server. After server has received the reply from the
3865 router will it send the reply to the client.
3867 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3868 broadcast received broadcast packet. The function is used only
3869 by router. The broadcast packet is always sent to the router's
3872 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3873 render given ID to printable string, for log files for example.
3875 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Made basic router to router connections working. At least they
3878 can now connect to each other but nothing really works the way
3879 they are supposed - yet.
3881 * Added new initiator token to RouterConnection configuration
3882 file in silcd/serverconfig.[ch]. It is used to tell whether we
3883 are the initiator to the remote router or whether we'll expect
3884 the other end to connect.
3886 * Moved registering of listener task to silc_server_init, hence
3887 the server starts listenning as soon as it is run, even if it
3888 does not have connections to other routers. Let's see how well
3891 * Changed default connection retry timeouts for more suitable in
3894 * Removed cipher and such arguments from silc_idlist_add_client
3895 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3896 Added new function silc_idlist_add_data to add the keys and stuff
3899 * Added SilcIDListData structure and added it to SilcClientEntry
3900 and SilcServerEntry as their first field in the structure. This
3901 way we can explicitly cast the ID entries to the SilcIDListData
3902 structure and get common data for the entries. In past, we had
3903 to first check what type of connection it is and then cast it to
3904 correct ID entry type. Now, we can directly cast the opaque
3905 pointer to the SilcIDListData (no matter what ID entry it actually
3906 is) and get the data needed.
3908 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3911 in some circumstances even if threre were timeout tasks, though not
3912 IO tasks, but tasks anyway. Now fixed.
3914 * Defined SilcServerConnection structure to hold connection specific
3915 stuff about directly connected servers and routers. The definition
3916 is currently in silcd/server_internal.h. I thought about having
3917 a bit more important role fro this struct but for now it is used
3918 only when connecting to other server (or router actually).
3920 * Added connecting retry support in server when connecting to
3921 router(s). The retry feature implement exponential backoff
3922 algorithm. Also, added SilcServerParams structure to hold default
3923 parameters for server. For now, it include these retry settings
3924 and are hard coded. After server is moded to be as Silc Server
3925 Library this structure will be more important.
3927 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Changed client librarys channel->clients table to SilcList and
3930 changed code accordingly.
3932 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3934 * Changed client's channel table to SilcList and changed code
3935 accordingly. Also changed SilcChannelClientEntry to include back-
3936 pointer to the channel so that client entry can use that structure
3937 as list as well and we have fast cross-reference to the channel.
3938 This change dramatically decreased the complexity of channel
3939 handling with client entry and vice versa (removed one extra
3940 loop when searching for channel entry from many functions).
3942 * Changed server->sim from table to SilcDList and changed code
3945 * NAMES command can now be used from user interface. It will show
3946 the user list on the channel, neatly.
3948 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3949 Code now saves realname of the user if it becomes available.
3951 * Renamed configure.in to configure.in.pre and made ./prepare
3952 script to automatically add correct version string to
3953 configure.in which it creates from configure.in.pre.
3955 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * NAMES command reply now shows users mode with the nickname when
3960 * Moved silc_client_ch[u]mode[_char] functions from
3961 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3962 place sucks, they are utility functions and should be in some
3965 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3967 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3970 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Added TRQ (efficient deque and list library) into lib/trq. This is
3975 a very good list library that is currently used in the SILC. Defined
3976 SilcList API over the library because I didn't like the API very
3977 much. See lib/trq/silclist.h for the API and examples of how to
3978 use the API. Fixed various places in the code to use the new
3979 SilcList API. The SilcList is meant for lists that has a structure
3980 already defined as a list. It is not suitable to add just some
3981 context to the list (in TRQ, the context is the list actually).
3983 So, I defined SilcDList that can be used for the purpose where
3984 predefined list structure does not exit. This can be used as
3985 such list. Now some context just can be added to the SilcDList.
3986 Currently this list is not used in the SILC just yet, though there
3987 are a lot places where this can replace dynamically allocated
3988 tables and I will fix these places, later, to use SilcDList.
3989 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3990 and use TRQ internally).
3992 Also fixed some annoying warning messages that the original TRQ
3993 code generated. Also minor changes to TRQ's Makefile.in.
3995 * Added support for querying by Client ID to both WHOIS and
3996 IDENTIFY commands into server, as required by the protocol.
3998 * Removed method function pointers from SilcBuffer structure. They
3999 weren't used to anything and just increased the context size for
4000 no good reason. This change also made silc_buffer_alloc and
4001 silc_buffer_free functions inline functions.
4003 * Disabled command flooding detection support until it's fixed so
4004 that it accepts commands in but does not execute them more than once
4007 * Added silc_net_localhost(), to return local hostname, into
4008 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4009 that must be initialized before calling silc_client_init.
4011 * Added new function: silc_server_send_notify_on_channels to send
4012 notify messages to all channels client has joined. It is assured
4013 that the message is sent only once per client.
4015 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4016 lib/silcutil/silcutil.[ch] as silc_format function. The new
4017 function is generic and is used by server as well, not only by
4018 the logging routines.
4020 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4021 the provided version string was not acceptable. Added new function:
4022 silc_ske_check_version into lib/silcske/silcske.h. The function
4023 must be implemented by the application (client or server) and it
4024 does not reside in the SKE library. The function checks the version
4025 string remote end sent.
4027 * Added back pointers (to opaque context and to SilcSocketConnection)
4028 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4030 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4031 duplicate packet context structure.
4033 * Changed `notify' client operation to send same arguments as client
4034 receives from server except for ID's. ID's are mapped to correct
4035 ID entry and that is returned. Also, if channel entry is not sent
4036 by server but the notify is for channel the channel entry is sent
4037 to application (otherwise application doesn't know that it is for
4038 channel (library gets it from packet's Destination ID)).
4040 * Added silc_client_remove_from_channels into client library to
4041 remove a client from all channels it has joined to. Used when
4042 received SIGNOFF notify from server. Added also new function
4043 silc_client_replace_from_channels to replace old ID entry with
4044 new ID entry on all channels. Used when received NICK_CHANGE
4047 * Fixed ID Cache list handling in silc_idlist_get_client in
4048 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4049 to get (or query) client by ID.
4051 * Updated TODO list.
4053 * Added connection authentication status message defined by the
4054 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4055 support for these into the code in client and server side.
4057 * Added generic function silc_client_send_command to send any command
4058 with variable argument list. Application should use this function
4059 to send commands if the command functions provided by the library
4060 does not suite for the application's user interface needs.
4062 * Added new `failure' client operation. Application is notified about
4063 received failure packet if client is executing a protocol. In this
4064 case the protocol's execution has failed.
4066 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4067 is required by the protocol.
4069 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4070 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4073 * Added status flag to SilcSKE object to indicate realtime status
4074 of the SKE protocol.
4076 * Application receives now exactly same command reply arguments as
4077 the library receives from server. However, if ID is received the
4078 corresponding ID entry is returned to the application (eg. Client
4079 ID is mapped to correct SilcClientEntry entry and that is returned).
4080 Changed command_reply client operation due to this change.
4082 * Changed all ID's in commands and in command replys as ID Payloads.
4083 Change affected both client and server side codes.
4085 All ID's sent in SILC network (with execption of ID's in SILC
4086 Packet header) are sent in ID Payload to support variable length
4089 * Server now notifies nick changes and notifies all clients on
4090 the channels about the new nickname (about the new Client ID,
4093 * Implemented CMODE command to change channel modes. Supports all
4094 channel modes defined by the protocol specs except ban and invite
4095 lists. (Also, private channel key mode is supported but support for
4096 setting private channel key in client is missing, thus, this mode
4097 has no effect on client side (except that server requires that the
4098 client uses private channel key and normal channel traffic does not
4101 Also, invite mode works per se, but INVITE command does not work
4102 yet correctly, so you can set channel as invite only channel but
4103 inviting clients to the channel does not work (it is yet to be
4104 thought what's the best way to do it).
4106 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4107 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4108 Implemented CUMODE command to change user's mode on the channel.
4109 Supports all modes defined by the protocol specs.
4111 * Added NAMES command reply to return users modes on the channel.
4113 * Removed unnecessary and slow ciphers from lib/silccrypt.
4115 * Set SO_KEEPALIVE option to connection sockets by default.
4117 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4119 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4120 redefined the Notify Payload into protocol specs.
4122 * Added silc_id_payload_parse_id to get ID directly from raw
4125 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4128 accept searching by Client ID as well.
4130 * Added support for LEAVE and SIGNOFF notify types in client library.
4132 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4133 to parse ID Payload from raw data.
4135 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added flags parameter into silc_ske_assemble_security_properties
4138 function in lib/silcske/silcske.[ch].
4140 * Changed notify client operation to fit better for notify messages
4141 sent by server. The notify payload received from server is now
4142 passed to the application (after parsing it to SilcNotifyPayload).
4143 It is application's responsibility to retrieve the arguments
4144 from the payload and show the message the way it wants. The message
4145 sent by server is implementation specific.
4147 * Changed public keys to comply with the protocol specification.
4148 Old public keys are not supported anymore and are not compatible.
4150 * Removed nickname from Channel Payload as the latest draft removed
4151 it. The client must resolve the nickname from the NAMES command
4152 reply received when it joined the channel.
4154 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4156 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Fixed some errors in protocol specification drafts.
4160 * Created lib/silccore/silcnotify.c to implement Notify Payload
4161 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4162 generic payloads described by protocol specifications. The file
4163 includes implementations for ID Payload and Argument Payload.
4165 * Changed Command Payload implementation to use the new Argument
4166 Payload. Changed command_xxxx_payload to command_payload_xxxx
4167 to comply with SILC coding conventions.
4169 * Added suppport for Argument Payload handling in Notify Payload
4170 implementation as protocol requires it. Added the new support
4171 into server and client lib as well.
4173 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Added support for multiple nicknames on same channel. [n] is
4176 added locally to the nickname if there are more than one same
4177 nicknames on the channel.
4179 * Server now sends all nicknames that matched WHOIS request.
4180 Client also shows the list received from server.
4182 * Added TOPIC command to client side. User can now set and show
4183 current topic on channel.
4185 * Added MOTD command to client and server. Also, server sends the
4186 motd when client connects to the server.
4188 * Changed version strings to comply ISO 8601.
4190 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Fixed protocol error handling in client library. It should now
4193 cope even if the SKE fails for some reason.
4195 * Made new protocol specification drafts for submitting to IETF.
4197 * Implemented TOPIC command to server in silcd/command.c.
4199 * Added two new notify types into lib/silccore/silcnotify.h:
4200 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4201 notify nickname change and topic setting/change on a channel.
4203 * API change of command_reply operation in client library. The
4204 application gets now the status type received from server as well.
4206 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4210 * Cras fixed and optimized the packet handling even further and
4211 it should work now. Minor change to the prototype of function
4212 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4214 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Added new function into lib/silcutil/silcschedule.[ch]:
4217 silc_schedule_with_fd to select() a specified fd. The function
4218 returns after timeout expires or data arrives or goes. The
4219 function is used by packet routines to wait that all data is
4220 received from network.
4222 * Fixed data reading from network in lib/silccore/silcpacket.c.
4223 The code now assures that all data is read from the fd and then
4224 continues packet processing. This was a bug fix since the code
4225 used to drop some data in some circumstances.
4227 * Added new function into lib/silcclient/client.[ch]:
4228 silc_client_start_key_exchange to start key exchange after
4229 connection has been established to server. The code internally
4230 now uses this funtion but its main purpose was to provide it
4231 for applications that perform their own connecting. After
4232 application has created a connection it merely calls this
4233 function to start the key exchange between client and server.
4234 The library takes care of everything else after that.
4236 Updated also lib/silcclient/README to explain the usage of
4239 * Do not send to application information that connection has
4240 been established. Application gets notified it by connect
4243 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Applied cras's patch to add silc_schedule_one function. The
4246 function runs scheduler once and returns.
4248 * Fixed the scheduler after cras messed it up. The timeout
4249 handling works now as it's supposed to work.
4251 * Added into lib/silccore/ silcnotify.h to include notify
4252 message types support. Changed silc_server_send_notify*
4253 functions, in server.[ch], to support those new notify types.
4254 Added the support for the notify types into client library,
4255 as well. Added new notify client operation into ops.h in
4258 * Changed silc_server_packet_send_to_channel to send normal
4259 packets instead of just channel message packets. The function
4260 is now used to send the notify packets to channels. It is not
4261 used to send channel message packets anymore, as server never
4264 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4265 va_arg()s as it seems to require it nowadays. I guess, if SILC
4266 is compiled with older va_arg() the new code should work anyway.
4268 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Splitted core library. Core library (lib/silccore) includes
4271 now only SILC protocol specific core (and common) components.
4272 Created new utility library (lib/silcutil) that includes more
4273 generic purpose stuff. The stuff for util library was taken
4274 from the old core library. This was minor and easy split.
4276 * Created SILC Client Library (lib/silcclient) that includes
4277 implementation of the SILC client without user interface. This
4278 was major move from silc/ directory. The code has been changed
4279 so that it is transparent towards the user interface. The
4280 silc/ directory includes now the same user interface as before
4281 and it uses the new client library. Read lib/silcclient/README.
4282 Basicly, the client library performs everything else related
4283 to SILC except user interface handling. Also, configuration
4284 files are considered to be part of user interface and library
4285 does not handle them.
4287 This change also changed a lot of structures, function naming etc.
4288 Most important change was that SilcClientWindow object was
4289 renamed to SilcClientConnection in the client library. Created
4290 also new file lib/silcclient/ops.h. Also added new files
4291 silc/local_command.[ch] and silc/client_ops.[ch].
4293 All these changes were made to make it easier for user interface
4294 designers to create what ever user interface for the SILC client
4297 It is also expected that the server will be moved to lib
4298 directory as well and SILC Server Library will be created;
4299 sometimes in the future.
4301 * Removed Local commands from lib/silccore/silccommand.h as
4302 they are application specific and new client library does not
4303 handle any of those anymore.
4305 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4306 old client implementation in silc/.
4308 * Added support for callback functions in SILC_LOG_* macros.
4309 Application can now set its own callbacks that will be called
4310 instead of using the default functions that will always print
4311 the debug messages to stderr (or stdout). Also, debugging can
4312 now be disabled by setting silc_debug to FALSE and re-enabled by
4313 setting it to TRUE. Note, that logging will still work even
4314 if debugging is disabled.
4316 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4317 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4318 silc_log_reset_debug_callbacks.
4320 * To enable debugging in silc client one must give now -d
4321 option on command line.
4323 * Changed silc_schedule_init to automatically allocate task queues
4324 if they are not allocated before calling it.
4326 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Added GMP 3.1 into math library.
4330 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4333 a channel in SILC network. The packet is used by servers and
4334 routers to notify other routers that user has left a channel.
4335 This little feature was missing until now. Added the feature
4336 to protocol specification as well.
4338 Added functions: silc_server_send_remove_channel_user and
4339 silc_server_remove_channel_user into server.[ch].
4341 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4342 lib/silccore/silcpacket.h. However, they are not implemented
4345 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Fixed joining to a channel and sending channel messages
4348 between server and router. The channel message sending should
4349 now work inside a cell.
4351 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Fixed the private message sending between server and router.
4354 The private message sending should now work inside a cell.
4356 * Added silc_server_replace_id into server.[ch] to replace
4357 existing ID in the SILC network.
4359 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4360 and silc_idlist_replace_server_id into idlist.[ch] in server.
4362 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Fixed the server to server connections. Server can again now
4365 connect to router. Router to router connections probably does
4368 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Added dynamic protocol registering support. Now protocols can
4371 registered and unregistered on the fly. Patch by cras.
4373 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added lib/contrib directory to hold routines that some platforms
4376 don't have but are needed by SILC.
4378 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4379 into lin/contrib to provide getopt() and getopt_long() for
4380 those who don't have it.
4382 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Added AWAY command to client. When away message is set and
4385 client receives a private message packet the client automatically
4386 replies to the sender with the away message.
4388 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4389 bug seemed to be the cause of recent problems when compiling
4392 * Added version detection support to SKE protocol specification
4393 and added the new changes to the SKE implementation as well.
4394 There were other minor changes in the SKE protocol as well.
4396 Many changes in lib/silcske/silcske.[ch] and in
4397 lib/silcske/payload.[ch].
4399 * Added ^U functionality, clear input line. Patch from cras.
4401 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Mainly small bugfixes on core library. Fixed some debugging
4404 logging and buffer overflow in silclog.c.
4406 * Updated config.sub and config.guess on the distribution tree.
4408 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Added command lagging support in server. Client may execute
4411 commands now only once in two seconds.
4413 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Optimized packet reception. MAC computation and checking is now
4416 also more optimized. A lot previously duplicated code is now
4417 used as generic by both client and server.
4419 * Fixed key pair generation in clientutil.c
4421 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Added into lib/silccore/silcbufutil.[ch] new function;
4424 silc_buffer_realloc.
4426 * Moved generic packet sending/encryption functions to
4427 lib/silccore/silcpacket.[ch] from client and server. Some
4428 rewriting of the functions.
4430 * Moved all generic packet reception/decryption functions to
4431 lib/silccore/silcpacket.[ch] from client and server. The
4432 packet processing is now much cleaner in both client and server.
4433 These were major changes in both client and server.
4435 * Created many common functions in server to do packet sending.
4436 Previously code were duplicated a lot, this has been removed
4439 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Rewrote major parts of the ID cache system. Don't know
4442 whether it is better now or not but at least the API is more
4445 * Major rewrite on ID cache stuff on client because of the ID
4446 cache API changes. Added idlist.c to client.
4448 * Also major rewrite on ID cache stuff on server as well.
4449 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4450 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4451 in hand, instead they are all put into the ID cache system now.
4452 All server_idlist_* routines uses ID cache now instead of
4453 traversing its own lists (those lists does not exist anymore).
4454 SilcIDList though still exists. Also, SilcXXXEntry's are
4457 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Finally made the SKE implementation compliant to the protocol
4460 specification. All mp integers are now binary encoded as
4461 opposed being HEX encoded.
4463 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4466 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4467 functions: silc_[encode/decode]_pem. Also added function
4468 silc_encode_pem_file to PEM encode with newlines ('\n') for
4471 * SILC public keys are now encoded either PEM or binary. Same
4472 option is for private keys as well. By default private keys
4473 are binary encoded and public keys PEM encoded. Silly HEX
4474 encoding were removed.
4476 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4477 function to create fingerprints.
4479 * Fixed a bug in SHA1; does not change the original data anymore.
4481 * Partly implemented INFO command on client and server side.
4482 Fixed CLEAR command. Changes to SERVER command; show current
4483 server(s) when giving command without arguments. Added
4484 VERSION command to client.
4486 * Added check to server that unregistered connections cannot
4487 execute commands (unless it is specificly allowed).
4489 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Fixed screen refresh.
4493 * Fixed channel joining bug from client. On some circumstances
4494 client tried to join to a channel it had already joined.
4496 * Added public key verification process into client's protocol.c.
4497 The client now verifies the public key from user and saves
4498 it into ~./silc/serverkeys/ directory.
4500 Added into: clientutil.[ch]: silc_client_verify_server_key.
4502 * Changed SKE protocol's silc_ske_initiator_finish function
4503 to accept callback function that verifies the received public
4504 key. Removed old silc_ske_verify_public_key function.
4506 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4509 silc_pkcs_private_key[_data]_set.
4511 * Made the password and public authentication more cleaner in
4512 server's protocol.c.
4514 * Removed historic and obsolete protocol `channel_auth' from
4515 both client and server.
4517 * Removed wrong way of sending command status messages from
4518 server to client in server's command.c. The old way violated
4519 protocol specification.
4521 Changes to silccore/silccommand.[ch]: removed
4522 silc_command_encode_status_payload -> not needed anymore,
4523 changed silc_command_encode_payload_va to accept extra
4524 argument on variable argument list. The argument type must
4525 now be provided to the function. Also, added new function:
4526 silc_command_encode_reply_payload_va which is same as
4527 normal command_encode_payload_va except command status type
4528 is provided as extra argument.
4530 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Added ~./silc directory handling. The directory includes the
4533 public and private keys for the client.
4535 Added silc_client_check_silc_dir, silc_client_create_identifier
4536 and silc_client_load_keys.
4538 * Implemented SILC protocol compliant public key. Added public
4539 and private key saving to and loading from files.
4541 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4542 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4543 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4544 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4545 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4547 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4548 silc_pkcs_load_[public/private]_key.
4550 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Added silc_server_get_route (route.[ch]) to get connection
4553 data for the fastest route for given ID.
4555 * Implemented INVITE command on client and server. The command
4556 were re-defined in the SILC Protocol Specification and the
4557 implementation now complies with the specification.
4559 * Implemented PING command on client and server.
4561 * Implemented NAMES command on client and server. The server side
4562 supports currently only normal server not router server yet.
4563 Some changes to NAMES definition in SILC protocol specification.
4565 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Implemented LEAVE command on client and server.
4569 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4570 again. This change was made to the protocol as well. Server
4571 should not violate the protocol specification anymore.
4573 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4576 was tested. SOCKS4 was not but should work anyway.
