1 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added for WIN32 support for the new scheduler as well.
4 Affected file lib/silcutil/win32/silcwin32schedule.c.
6 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
8 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
9 API. It is part of the scheduler now. Everything else is
10 as previously but some functions has changed their names.
11 Checkout the lib/silcutil/silcschedule.h for the interface.
12 Updated all applications to use the new interface. Affected
13 files are lib/silcutil/silcschedule.[ch].
15 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
17 * Found a bug in the SKE implementation. The HASH value,
18 specified by the protocol, was not computed correctly. The
19 public key of the responder was not added to the computation
20 even though it is mandatory. Affected file lib/silcske/silcske.c.
21 This unfortunately causes incompatibilities with older
24 * Added WIN32 specific network init and uninit functions:
25 silc_net_win32_init and silc_net_win32_uninit to init and uninit
26 the Winsock2. Affected file lib/silcutil/silcnet.h and
27 lib/silcutil/win32/silcwin32net.c.
29 * Set the socket always to nonblocking mode on WIN32 after
30 reading data or writing data. Affected file is
31 lib/silcutil/win32/silcwin32sockconn.c.
33 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
35 * Fixed various compilation problems under WIN32. Affected
36 files lib/silcutil/win32/silcwin32thread.c and
37 lib/silcutil/win32/silcwin32schedule.c.
39 * Removed all _internal.h #includes from public header
40 files. Internal headers must never be included from
43 Removed also the lib/silcske/payload_internal.h file.
45 * All include files that may be needed (public and some others
46 included by the public headers) by application developers are
47 now copied to the ./includes directory. It does not copy any
48 internal headers. Affected file Makefile.defines.pre and all
49 Makefile.am's under lib/ and subdirs.
51 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
53 * Do not change the ~/.silc directory's permissions automatically.
54 Affected file irssi/src/silc/core/clientutil.c.
56 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
58 * Do not cancel the protocol in silc_server_close_connection
59 it might cause recursion. Now cancelled in the function
60 silc_server_free_sock_user_data. Affected file silcd/server.c.
62 * Fixed the silc_server_remove_clients_by_server to regenerate
63 the channel keys correctly finally. Added also new function
64 silc_server_remove_clients_channels to actually do it.
65 Affected file silcd/server.c.
67 * Fixed the silc_server_new_channel to not crash by giving
68 wrong router to the new channel. Affected file is
69 silcd/packet_receive.c.
71 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
73 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
74 which is given as argument to the silc_client_alloc now.
75 It can be used to configure the client and set various parameters
76 that affect the function of the client.
78 * The USERS command in server did not check whether the channel
79 is private or secret. Affected file silcd/command.c.
81 * Added new argument to the USERS command in protocol specification.
82 The USERS command now can take the channel name as argument
83 as well. Added support for this in client and server and
84 updated the protocol specs.
86 * Completed the GETKEY command in client. It can be now used
87 to fetch also servers public key not only some clients.
88 Affected files lib/silcclient/command[_reply].c.
90 * Added silc_client_get_server to return server entry by the
91 server name. Affected files lib/silcclient/silcapi.h and
94 * Redefined the IDENTIFY command in protocol specification to be
95 more generic. It now can be used to query information about
96 any entity in the SILC Network, including clients, servers and
97 channels. The query may be based either the entity's name
98 or the ID. Added support for this in both client and server.
100 Affected files silcd/command.c and lib/silcclient/command.c
103 * Optimized the WHOIS and WHOWAS commands in the server. Removed
104 the _from_client and _from_server functions. Affected file
107 * Added silc_client_get_channel_by_id_resolve to the file
108 lib/silcclient/silcapi.h to resolve channel information by
109 its ID. Added also silc_client_get_channel_by_id that
110 does not resolve it from the server.
112 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
114 * Added SilcServerEntry context into the client library
115 to represent one server. The INFO command now allocates
116 these to save the resolved server info. For now on the
117 client library will also keep information about servers,
118 connected and resolved with INFO.
120 The INFO command now allocates the SilcServerEntry context
121 and saves the server info there. The COMMAND_REPLY in
122 the INFO now returns the parameters to application in
123 same order as defined in the protocol specification.
125 The entries are cached in the client->server_cache.
127 * The INFO command is now issued after received the Client ID
128 from the server. Affected file lib/silcclient/client.c.
130 * The CMODE_CHANGE notify may now return also an SilcServerEntry
131 to the application as the mode changer might be server.
132 It is guaranteed that NULL is not returned anymore to the
133 application. Affected file lib/silcclient/client_notify.c.
135 The ID Type is now also passed to the application so that
136 it can check whether the returned entry is SilcClientEntry
139 Added new function silc_client_get_server_by_id to return
140 the server entry by ID. Affected files are the
141 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
143 * Do not create the channel in the Irssi SILC Client when issuing
144 the JOIN command but when received the sucessful JOIN command
145 reply. Otherwise the channel might get created even though we
146 could not join it. The Affected file is
147 irssi/src/silc/core/[silc-channels.c/client_ops.c].
149 * Fixed a channel joining bug in router. The router must also
150 check the channel modes, invite and ban lists etc. when serving
151 the JOIN command sent by normal server. Affected file is
152 silcd/command.c. The router now resolves the client's
153 information from the server who sent the JOIN command if it
154 does not know it, and processes the JOIN command only after
157 * Changed the SilcCommandCb to take new argument; void *context2.
158 Affected file lib/silccore/silccommand.h
160 The second argument in the command callbacks in the server now
161 includes the SilcServerCommandReplyContext if the command was
162 called as pending command callback from the command reply.
163 Otherwise it is NULL. When called as pending the status of the
164 command reply will be checked and if it was erronous the
165 error will be sent to the original sender of the command.
166 This way the client always receives the error messages even
167 though the server was actually the one who received the error
168 when it resent the command to router, for example. Affected
169 files silcd/command[_reply].[ch].
171 * Fixed sending WHOWAS command's error message to client if
172 the requested client could not be found. It was missing.
175 * Changed the CMODE and CUMODE commands reply arguments in the
176 protocol specification. The Channel ID is now sent in both
177 of the commands to identify the channel. Implemented this
178 new feature to the client and server. Affected files
179 lib/silcclient/command_reply.c and silcd/command.c.
181 * Made better checks for invite and ban lists in the JOIN
182 command in server. Affected file silcd/command.c.
184 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
186 * The server now performs the incoming host IP/DNS lookup
187 using the silc_socket_host_lookup and thus does not block
188 the server anymore. Affected file silcd/server.c.
190 * Completed the multi-thread support for SILC Scheduler in
191 the lib/silcutil/silcschedule.c.
193 * Fixed the configure.in.pre to detect the pthread correctly
196 * Fixed a deadlock in silc_task_queue_wakeup in the file
197 lib/silcutil/silctask.c.
199 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
201 * Added new function silc_schedule_wakeup that is used in
202 multi-threaded environment to wakeup the main thread's
203 schduler. It needs to be used when a thread adds a new task
204 or removes a task from task queues. After waking up, the
205 scheduler will detect the task queue changes. If threads
206 support is not compiled in this function has no effect.
207 Implemented the wakeup mechanism to both Unix and WIN32
208 systems. Affected files are lib/silcutil/silcschedule.[ch],
209 lib/silcutil/unix/silcunixschedule.c and the
210 lib/silcutil/win32/silcwin32schedule.c.
212 * Added new function silc_task_queue_wakeup to wakeup the
213 scheduler by the specified task queue. Affected file
214 lib/silcutil/silctask.[ch].
216 * The silc_socket_host_lookup_start now wakes up the scheduler
217 after adding the timeout task. Affected file is
218 lib/silcutil/silcsockconn.c.
220 * The silc_socket_host_lookup is synchronous now if the threads
221 support is not compiled in. However, the callback is still
222 called asyncronously through the scheduler, anyway. Affected
223 file lib/silcutil/silcsockconn.c.
225 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
227 * Added new function silc_socket_host_lookup to perform
228 asynchronous IP and FQDN lookups for the socket connection.
229 Affected files lib/silcutil/silcsockconn.[ch].
231 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
233 * Added SILC_MUTEX_DEFINE to define the mutex on environments
234 that may or may not compile the mutex support in.
236 Changed the silc_mutex_alloc interface. It allocates the
237 mutex now to the sent pointer and returns TRUE or FALSE.
239 Affected file lib/silcutil/silcmutex.h.
241 * Wrote the SILC Task Queue interface to support multi-threads.
242 Affected file lib/silcutil/silctask.[ch].
244 * Wrote the SILC Scheduler to support multi-threads. Affected
245 file lib/silcutil/silcschedule.c.
247 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
249 * Implemented the SILC Mutex API and SILC Thread API for WIN32
250 in lib/silcutil/win32/.
252 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Defined SILC Mutex API and SILC Thread API and implemented
255 them for Unix. Affected files are
256 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
257 lib/silcutil/unix/silcunixmutex.c and
258 lib/silcutil/unix/silcunixthread.c.
260 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Fixed the silc_server_remove_clients_by_server's channel
263 key re-generation. The hash table handling was incorrect
264 and would not work with many channels. Affected file is
267 * Fixed some memory leaks around the server code.
269 * Rewrote the silc_server_get_users_on_channel to support IPv6
270 based Client ID's. Affected file silcd/server.c.
272 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
273 specification. However, a separate document must be written
274 to define the detailed signing procedure and the payload
275 associated with the flag. Defined the flag to the
276 lib/silccore/silcchannel.h as well.
278 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
280 * Changed the dynamic tables to static size tables in the
281 lib/silccrypt/silchmac.c.
283 * Removed GCC dependencies from the code. A patch by cras.
285 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
287 * Do not show the error "Error receiving packet bla bla"
288 in server if it really was not an error (-2 means that reading
289 is pending). Affected file silcd/server.c.
291 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
293 * Fixed a possible crash in silc_server_remove_clients_by_server
294 in silcd/server.c. Fixed there also some memory leaks.
296 * Fixed the silc_idlist_replace_client_id. It could replace
297 wrong key in the hash table. Affected file silcd/idlist.c.
299 * Do not check whether there are global users on the channel
300 if the channel->global_users is FALSE. Affected functions
301 silc_server_remove_from_one_channel and
302 silc_server_remove_from_channels in silcd/server.c. Also,
303 do not check if the removed client is local as we can be
304 sure that global client was not removed from the channel
305 and checking for global users is not needed.
307 * The silc_server_remove_clients_by_server now re-generates
308 the channel keys correctly for those channels that had
309 clients removed from them. Affected file silcd/server.c.
311 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
313 * Found the reason of random crashes in the server. We weren't
314 ignoring the SIGPIPE signal (which can be sent in write())
315 and it crashed the server. Affected file silcd/silcd.c.
317 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
319 * Assure that sock->user_data is not NULL in the function
320 silc_server_packet_send in silcd/packet_send.c.
322 * Disconnect the remote connection if it could not be added
323 to any ID lists in the server. The affected file is
326 * Check in silc_server_packet_send[_real/dest] that the
327 socket is not disconnecting and ignore the data if it is.
328 Affected file silcd/packet_send.c.
330 * Define inline to __inline on native WIN32 compilation.
331 Affected file includes/silcwin32.h.
333 * Added some explicit type casts for inline code since MSVC
334 require them. Affected files lib/silcutil/silcbuffer.h,
335 lib/trq/silcdlist.h and lib/trq/silclist.h.
337 * Print warning in log files from now on if the packet
338 decryption fails. Affected file silcd/server.c.
340 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
342 * Changed the `say' client operation's interface to accept
343 new `type' argument to indicate the type of the message sent
344 by the library. The application may filter the library's
345 messages according the type. The affected file is the
346 lib/silcclient/silcapi.h.
348 * Added two new functions to lib/silcclient/silcapi.h:
349 silc_client_del_client and silc_client_del_client_by_id.
350 Affected file lib/silcclient/idlist.c.
352 * Moved the clientincludes.h from includes/ to silc/ and
353 serverincludes.h from includes/ to silcd/.
355 * The modes for the CMODE and CUMODE are now passed as
356 uint32 for application with COMMAND_REPLY. The affected
357 file is lib/silcclient/command_reply.c.
359 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
361 * /WHOIS without arguments shows client's own information.
362 Affected file lib/silcclient/command.c.
364 * Changed PING to not accept any arguments. The specs
365 says that client can ping only the connected server so
366 requiring an argument is not needed. Affected file is
367 lib/silcclient/command.c.
369 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Fixed a fatal bug in private message sending and reception
372 encryption and decryption when using private message keys.
373 The implementation was incorrect and did not follow the
374 specification. It causd that some of the message were
375 lost since it did not use the sending and receiving keys
376 as the protocol suggests. This has been fixed and will cause
377 incompatibilities with older clients when sending private
378 message encrypted with private message keys. Affected files
379 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
380 and various other in Irssi SILC Client.
382 Added `responder' boolean argument to the functions
383 silc_client_add_private_message_key[_ske] to indicate when
384 the key is added as responder or initiator of the key
387 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
389 * Removed the silc_ske_check_version function and created
390 a SilcSKECheckVersion callback. Added also a function
391 silc_ske_set_callbacks that is now used to set all SKE
392 callbacks. The callback functions are not given to
393 the SKE functions anymore, but this function is used to
396 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
398 * Added `silc_version' argument to the silc_client_alloc
399 to define the version of the application for the library.
400 The library will use the version string to compare it
401 against the remote host's (usually a server) version
402 string. Affected file lib/silcclient/silcapi.h
404 * Added the KE protocol context to Key Agreement context
405 in client library so that we can abort the SKE if it
406 is in process when we get timeout. Affected file is
407 lib/silcclient/client_keyagr.c.
409 * Do not resolve the client ID forever if it returns in the
410 first time that such client does not exist. This was done
411 for example with private message. Affected file is
412 lib/silcclient/client_prvmsg.c.
414 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
416 * Do not add regex.h for WIN32. The affected file
417 includes/silcincludes.h.
419 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
420 not work yet 100%. It generates the DLL's automatically
421 when compiling with --with-win32 under cygwin.
423 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
425 * lib/contrib/regex.c is not compiled on WIN32.
427 * Added silc_net_get_socket_opt function to the
428 lib/silcutil/silcnet.h.
430 * Added includes/silcwin32.h for WIN32 specific includes
433 * Do not use ptime structure or any of the posix process
434 functions on WIN32 in lib/silccrypt/silrng.c.
436 * Added silc_gettimeofday to provide generic function
437 for struct timeval on all platforms. Added the function
438 to lib/silcutil/silcutil.h.
440 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
442 * Moved the lib/silccore/silcsockconn.[ch] to the utility
443 library as they clearly belong there. As a plus side we
444 can make the actual socket connection routines platform
447 Added also new generic function silc_socket_read and
448 silc_socket_write (that used to be silc_packet_[read/write].
449 The implementation of these are platform specific.
451 * Added WIN32 specific routines of silc_socket_[read/write]
452 to lib/silcutil/win32/silcwin32sockconn.c.
454 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
456 * Added preliminary support for native WIN32 compilation under
457 cygwin (using the -mno-cygwin option for GCC) to the
458 ./configure.in.pre. The --with-win32 now prepares the
459 compilation for native WIN32.
461 * Rewrote the SILC Scheduler interface in the file
462 lib/silcutil/silcschedule.h. The scheduler is now context
463 based and does not have anymore any global static scheduler.
464 Moved the Unix scheduler to the lib/silcutil/unix/ directory
465 and created lib/silcutil/win32 directory for WIN32 based
468 * Added Unix specific network routines to the
469 lib/silcutil/unix/silcunixnet.c and the old
470 lib/silcutil/silcnet.c includes now only generic routines.
472 Added WIN32 specific network routines to the
473 lib/silcutil/win32/silcwin32net.c.
475 * Added Unix specific utility functions from the
476 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
478 * Added WIN32 SILC Scheduler to the file
479 lib/silcutil/win32/silcwin32schedule.c. The code is of course
482 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
484 * Do not handle JOIN notify in the server if the target client
485 is not registered (idata->registered == FALSE). The affected
486 file is silcd/packet_receive.c.
488 * Update the nickrec->founder in event_cumode in the Irssi SILC
489 client. Affected file irssi/src/silc/core/silc-channels.c.
491 * Fixed the CUMODE_CHANGE notify handling in the server when
492 server and router are announcing their clients on channels.
493 Now the mode changes are saved and notified correctly. The
494 affected file is /silcd/packet_receive.c.
496 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
497 They really did not replace the cache entry in the ID Cache.
498 Now they do that. Affected file silcd/idlist.c.
500 * Fixed the KICK notify handling in the Irssi SILC client to
501 update the channel records so that the kicked client does not
502 appear to be on the channel. The affected file is
503 irssi/src/silc/core/silc-channels.c.
505 * Always update the conn->current_channel when executing command
506 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
508 * Fixed the KILL notify handling in Irssi SILC client to remove
509 the killed client on all channels.
511 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Fixed the silc_parse_command_line to remove extra spaces
514 from the start and end of the arguments. Affected file is
515 lib/silcutil/silcutil.c.
517 * Cancel and free any active protocol in the function
518 silc_server_close_connection. Affected file silcd/server.c.
520 * Cancel and free any active protocol in the function
521 silc_client_close_connction. Affected file is
522 lib/silcclient/client.c.
524 * Do not execute the KILL command for clients that are in
525 history (ie. they are not in the network). Affected file is
528 * Fixed KILL notify handling, client does not crash anymore.
529 Affected file irssi/src/silc/core/silc-channels.c.
531 * Reduced the default packet buffer size from 2048 to 1024 in
532 lib/silccore/silcpacket.c.
534 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
535 counter to the SKE context that is incresed when the SKE library
536 performs async operation outside the library. If the outside
537 process frees the SKE context and FREED status will be set
538 and the library will detect after the sync operation that the
539 libary is freed. The affected files are
540 lib/silcske/silcske[_status].[ch].
542 * Resolve the client entry information in the function
543 silc_client_channel_message to assure that NULL pointer is not
544 passed as client entry to the application. */
546 * Fixed the task timeout calculation to assure that there is
547 never negative timeouts. The affected file is
548 lib/silcutil/silcschedule.c.
550 * Fixed the channel user mode notification sending in server.
551 It was sent point-to-point to the router (or to server by router)
552 but it needs to be destined to a channel. The routines now
553 supports sending the channel user mode notifys to the channels
554 when announcing clients and channels. Affected files are
555 silcd/server.c and silcd/packet_receive.c.
557 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
558 It did not actually replace the old channel entry in the cache.
559 Affected file lib/silcclient/client_notify.c.
561 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Fixed a possible crash in silc_packet_send_prepare. It now
564 assures always that there is enough space in the buffer and
565 at the tail area of the buffer (for MAC).
567 Fixed the inbound buffer reallocation in silc_packet_read.
568 It was old code and did not handle the reallocation correctly.
571 The affected file is lib/silccore/silcpacket.c.
573 * Fixed buffer overflow in silc_parse_nickname in the file
574 lib/silcutil/silcutil.c.
576 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
578 * make install generates new server keys only if there is not
581 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
584 Added check that if the NOREPLY is set then we will not send
585 the away message. This avoids infinite loop of away messages
586 if both clients are away. The affected file is
587 lib/silcclient/client_prvmsg.c.
589 * Fixed client crash if /NICK was given without arguments.
590 Affected file lib/silcclient/command.c.
592 * Server does not send the invite list in INVITE command back
593 to the client if the list was not altered. Added this notion
594 to the protocol spec as well. Affected file silcd/command.c.
596 Fixed possible crash in INVITE command by checking the
597 value of silc_server_get_client_route command.
599 * Fixed the INVITE notify type handling. The arguments are now
600 taken in correct order and client does not crash. The affected
601 file is irssi/src/silc/core/silc-channels.c.
603 Removed the "Inviting xxx to channel" message from the
604 client library away and let the application handle it.
605 Affected file lib/silcclient/command.c. Added that message
606 to Irssi SILC client's message formats.
608 * Fixed CMODE command crash in client. It now checks the
609 amount of arguments correctly and does not crash. The affected
610 file is lib/silcclient/command.c.
612 * Do not create new channel automatically in silc_channels_join
613 but check whether the channel by that name already exists.
614 Affected file irssi/silc/core/silc-channels.c.
616 * Do not send the SERVER_SIGNOFF to router if the disconnected
617 entity was the router. Affected file silcd/server.c.
619 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
620 SILC client as it was missing from there.
622 Added the handling of the KICK notify to the Irssi SILC client
623 as it was missing. Added "you have been kicked" message to
624 Irssi SILC client's message modules formats.
626 Added the handing of the KILL notify to the Irssi SILC client
627 as it was missing. Added the kill message module formats
630 The affected file is irssi/src/silc/core/silc-channels.c.
632 * The router did not save the channel mode the server announced.
633 Affected file silcd/packet_receive.c.
635 * Fixed a possible crash in INFO command in server. If the
636 server did not provide the server info it crashed. Affected
637 file silcd/command.c.
639 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Fixed the GETKEY command in the server to check also the
642 global list. Otherwise the GETKEY would not work correctly
643 in normal SILC server. Affected file silcd/command.c.
645 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
647 * Fixed GETKEY crash, it crashed if the command did not succseed.
649 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
652 is now real and not just an macro interface to GMP.
654 Removed the entire GMP from the source tree and imported new
655 NSS MPI library instead. Reason for removing GMP is that it is
656 extremely large and compiles extremely slow. The NSS MPI
657 is only a few files and compiles in less than 10 seconds.
658 The speed is also about the same as GMP. The MPI is imported
661 If the system has GMP installed we will still use the GMP.
662 If it is not then the NSS MPI will be compiled.
664 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
666 * Merged a long nickname (127 characters long) crash bugfix from
667 Irssi CVS tree. Affected file irssi/src/core/misc.c.
669 * Merged a freed memory reference bugfix from Irssi CVS tree.
670 Affected file irssi/src/core/commands.c.
672 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Added the server's public key sving and verification to the
675 server when performing the SKE. This was missing and the
676 remote server's (or router's) public key was accepted without
677 checking whether we have it previously or trust it at all.
678 Affected file silcd/protocol.c.
680 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * Check in the silc_server_timeout_remote if protocol is active
683 and make sure that the protocol's final callback is called so
684 that all memory if freed. Affected file silcd/server.c.
686 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * silc_server_whois_send_reply crashed the server if the nickname
689 was 127 characters long. Affected file silcd/command.c.
691 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Added sanity check to the silc_server_new_client. If the hostname
694 is provided inside username then check that the provided hostname
695 really is the same as the resolved one. If the hostname was not
696 resolved then check it from the public key. Affected file is
697 silcd/packet_receive.c.
699 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
700 if the server disconnected us and the connection is not valid
701 anymore. Affected file irssi/src/silc/core/silc-channels.c.
703 * Moved the silc_client_[chmode|chumode|chumode_char] away from
704 the library to the lib/silcutil/silcutil.[ch].
706 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Close log file after open. Affected file
709 lib/silcutil/silclog.c.
711 * Check whether sock == NULL in silc_client_send_packet and return
712 if it is. Affected file lib/silcclient/silcclient.c.
714 * Check rec->entry == NULL in the Irssi SILC Client before
715 sending the channel message. Affecte file is
716 irssi/src/silc/core/silc-servers.c.
718 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Merged a splitted window bugfix from Irssi CVS tree. The
721 affected file is irssi/src/fe-text/textbuffer-view.c.
723 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
724 It did not print nickname.
726 * Improved the distributions system a bit.
728 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
731 irssi/src/fe-text/gui-window.c.
733 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
734 to in-active server. The affected file is
735 irssi/src/silc/core/client_ops.c.
737 * Resolve the client in USERS command reply if the entry does
738 not have username resolved. The affected file is
739 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
740 command to WHOIS command to really resolve stuff. The USERS
741 is not used any more in any critical section so WHOIS can
742 be used even though it might be slower than IDENTIFY.
744 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
747 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Changed the protocol API a bit more consistent in the
750 lib/silccore/silcprotocol.[ch].
752 * Changed the following headers to ROBODoc format:
754 lib/silccore/silcpayload.h
755 lib/silccore/silcprotocol.h
756 lib/silccore/silcsockconn.h
758 All core library headers are now formatted.
760 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
762 * Fixed a bug in Irssi SILC client; do not show that you are
763 server/router operator if you really are not. Affected file is
764 irssi/src/silc/core/client_ops.c.
766 * Renamed silc_command_free_payload to silc_command_payload_free.
767 Affected file lib/silccore/silccommand.h
769 * Added silcmath.h to include the prototoypes of various routines
770 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
773 * Changed the following headers to ROBODoc format:
775 lib/silccore/silcchannel.h
776 lib/silccore/silccommand.h
777 lib/silccore/silcid.h
778 lib/silccore/silcidcache.h
779 lib/silccore/silcmode.h
780 lib/silccore/silcnotify.h
781 lib/silccore/silcpacket.h
782 lib/silcmath/silcmath.h
784 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
786 * Added checking to the server code not to start the server if
787 ciphers and stuff are not configured properly. Affected files
788 silcd/serverconfig.[h] and silcd/server.c.
790 * Changed the layout of the header files of the public interfaces
791 in the SILC libraries. The new layout supports ROBODoc
792 documentation tool (and some others) so that it is easy to create
793 a library reference manual. All the other headers and source
794 code must still follow the CodingStyle document. Also source
795 code must not include these ROBODoc stuffs, only the headers.
796 Furthermore, all public interface headers must now be named
797 by using `silc' prefix, example: silcapi.h, silccipher.h.
798 Some files were renamed due to this. All the other headers
799 must not be used as public interfaces. I will update the
800 CodingStyle document later. Changed following headers, so far:
802 lib/silcclient/silcapi.h
803 lib/silccore/silcauth.h
804 lib/silccore/silcprivate.h
805 lib/silccrypt/silcdh.h
807 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Removed silc_client_packet_send_flush from the client library
812 as it is not needed. Affected file lib/silcclient/client.[ch].
814 * Added printing of message of unresolved authentication method
815 to the Irssi SILC client. Added it to the module formats.
816 Removed the same message from the client library.
818 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Added new distribution feature, DISTLABEL. Every distribution
821 can define own preprocessor label that can be used in the
822 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
823 file distributions, acconfig.h.pre and prepare.
825 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Added Makefile.defines_int to include the actual definitions
828 for Makefile.defines.in. Tested the new distribution system,
829 created distributions and tested installation.
831 * Added AWAY message printing to the Irssi SILC client. Added
832 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
834 * Added SCONNECT command to call the SILC's CONNECT command.
835 Cannot use CONNECT directly since Irssi uses that internally.
836 Affected file irssi/src/silc/core/silc-servers.c.
838 Added ACTION local command. It is same as ME command but takes
839 the channel as mandatory argument.
841 Rewrote some of the Irssi's help files to suite for SILC
844 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Added Makefile.defines[.in] that should for now on be included
847 in all Makefile.am file in the source tree. That file includes
848 all common compilation definitions for SILC source tree.
850 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Minor changes to the ./prepare script to change the package
853 name according the distribution name to the configure.in.
855 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Created new distribution system. Added file `distributions'
858 that defines all the distributions that can be created out of
859 the SILC source tree. The ./prepare script now reads that
860 file to determine how to prepare the distributions. The
861 first argument to the ./prepare is the name of the distribution
862 and second is the version of the distribution. If given
863 without arguments it creates the default (toolkit) distribution
864 with the default version (defined in ./prepare).
866 All Makefile.am files that are subject to the distributions
867 are now named as Makefile.am.pre. These are ./Makefile.am
868 and lib/Makefile.am. Others may be changed later.
870 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
872 * Added invite list, ban list, some key management and connection
873 error message printing to module formats in the Irssi SILC client.
875 * Added new silc_client_set_away_message to set the away message
876 that is back to the person who sent private message. The
877 affected file lib/silcclient/silcapi.h and the
878 lib/silcclient/client_prvmsg.c.
880 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Fixed the private message sending in the Irssi SILC client,
883 added local command KEY to the Irssi SILC client.
885 Added key management and key agreement message formats to the
886 irssi/src/fe-common/silc/module-formats.[ch].
888 Added USERS (alias WHO) printing, server/router operator
889 indication and LIST command printing to the module formats.
891 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Fixed channel joining notify handling, cumode notify handling
894 from Irssi SILC client.
896 * Added SILC specific module-formats to the Irssi SILC client so
897 that SILC specific message hilighting, colors etc is possible.
898 Affected file irssi/src/fe-common/silc/module-formats.[ch].
900 Added channel mode, channel user mode, actions, notices,
901 whois and whowas printing to the the module-formats.c.
903 * Fixed a bug in channel deletion in the server. The channel
904 is not left to the cache even if the channel founder auth mode
905 is set when there are no users anymore on the channel. Affected
908 * The silc_net_localhost now resolves the entire hostname including
909 the domain name. Affected file lib/silcutil/silcnet.c.
911 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
913 * Changed the ask_passphrase client operation to be ascynchronous.
914 It has now a completion callback and a context that the
915 application must call after it has got the passphrase from
916 the user. Affected files lib/silcclient/silcapi.h,
917 lib/silcclient/protocol.c, lib/silcclient/command.c and
920 Added SilcAskPassphrase callback that the application calls
921 to deliver the passphrase to the library.
923 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
924 The public key verification and especially a certificate
925 verification is asynchronous procedure.
927 Added new SILC_SKE_STATUS_PENDING status to indicate the
928 request is pending and a callback will be called to finalize
931 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
932 indicate that remote end did not send its public key (or
933 certificate), even though we require it. Added check for this
934 condition in the SKE. This was a security bug, now fixed.
936 Defined new SilcSKEVerifyCbCompletion callback that is called
937 when the verification process is completed.
939 The affected files lib/silcske/silcske_status.h and
940 lib/silcske/silcske.[ch].
942 * Changed the verify_public_key client operation to be async
943 as well. Defined SilcVerifyPublicKey callback that is used to
944 indicate the success of the public key verification process.
946 Changed the server and client to use the new async client
949 * Changed the Irssi SILC client's internal scheduler to be called
950 twice as many times as it used to be. As a result the client
951 should be a bit faster now. Affected file is
952 irssi/src/silc/core/silc-core.c.
954 * Added support to Irssi SILC client of asynchronous public key
955 verification and passphrase inquiry. Affected file is
956 irssi/src/silc/core/silc-core.c.
958 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Do not say "You have left channel %s" in client library.
961 Moved it to the application. Affected files are
962 lib/silcclient/command.c and silc/client_ops.c.
964 * Fixed silc_client_get_clients. Command context was not
965 duplicated and was freed memory in the callback. Affected
966 file lib/silcclient/idlist.c.
968 * Do not say "you are now talking..." on JOIN command in the
969 client library. The appliation must handle it.
971 * Do not say ".. changed topic to" in command reply in the
972 client libary. The application must handle it.
974 * Fixed TOPIC command sending in the client library.
976 * Fixed a memory leak in silc_client_command_free in the file
977 lib/silcclient/command.c.
979 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Imported a modified version of Irssi client to the source tree.
982 The Irssi will be used to create a new client called
983 Irssi SILC. Imported to irssi/.
985 Added silc_core_init_finish function to the Irssi. Affected
986 file irssi/configure.in.
988 A lot changes in the Makefile.ams around the irssi tree.
990 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Do not rehash if the new size is same as the old size of the
993 hash table, in the silc_hash_table_rehash*. The affected file
994 lib/silcutil/silchashtable.c.
996 * Replaced hash_table_del_by_context calls from the server
997 (when channel->user_list and client->channels) to the
998 hash_table_del as it is sufficient and faster.
1000 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Added silc_hash_table_list, silc_hash_table_get and the
1003 SilcHashTableList structure to provide an alternative way to
1004 traverse the hash table. The affected files are
1005 lib/silcutil/silchashtable.[ch].
1007 * Changed the server's idlist routines to use the hash table
1008 routines to optimize the code.
1010 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Replaced the client entry's `channel' list and channel entry's
1013 `user_list' list to hash tables for optimized lookup. Changed
1014 the code to use the hash table interface around the code.
1015 Affected file lib/silcd/idlist.[ch].
1017 * Added `auto_rehash' boolean argument to the function
1018 silc_hash_table_alloc to indicate whether the hash table should
1019 auto-rehash when it thinks is appropriate time. It will
1020 increase the hash table size if the there is twice as much
1021 entries in the table than the size of the table, and will
1022 decrease the size if there are twice as less entries than
1023 the size of the table.
1025 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1029 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * silc_idcache_purge_by_context deletes the entry now by context
1032 as it is supposed to do. Affected file lib/silccore/idcache.c.
1034 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1035 client is not anymore valid (WHOWAS givens the info) and not
1036 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1038 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * Removed the `data' and `data_len' arguments from the ID Cache
1041 interfaces and added `name' argument. ID Cache does not handle
1042 anymore the binary data only a names associated with given ID.
1044 * When hashing a Client ID with silc_hash_id the entire ID is
1045 not hashed anymore, instead only the hash of the Client ID is
1046 hashed. This way we can access the Client ID from the cache
1047 with Client ID but with the hash of the ID (which is a hash of
1048 the nickname) as well without any difference in performance.
1050 Added also silc_idcache_find_by_id_one_ext to do one on one
1051 searching when we have the actual ID. Added also function
1052 silc_hash_client_id_compare. The affected files are
1053 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1055 * When hashing the name associated with a ID it is always done
1056 in lowercase. This way we can access the cache without worrying
1057 about case-sensitivity, even though, for example nicknames are
1060 * Fixed a bug in server with channel message sending. It put
1061 wrong ID type as destination ID. The affected file
1062 silcd/packet_send.c.
1064 * silc_idcache_del_by_context now deletes from all hash tables
1065 by context. Affected file lib/silccore/idcache.c.
1067 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Changed the client library to use the new ID Cache interface.
1070 Changes around the source tree.
1072 * Added silc_hash_table_rehash_ext to rehash with specific
1073 hash function. Affected file lib/silcutil/silchashtable.[ch].
1075 * Added silc_hash_string_compare to compare two strings in the
1076 hash table. Affected file lib/silcutil/silcutil.[ch].
1078 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Added new function silc_idcache_del_by_context into the
1081 lib/silccore/idcache.[ch].
1083 * Changed the server's ID list routines to use the new ID Cache
1084 interface. Changes around the source tree.
1086 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Added silc_hash_table_del[_by_context]_ext functions in to the
1089 lib/silcutil/silchashtable.[ch].
1091 Removed silc_hash_table_find_all* routines and added new
1092 silc_hash_table_find_foreach to replace them.
1094 Added silc_hash_table_replace_ext function as extended
1095 replacing function. Separated the simple hash table interface
1096 from the extended hash table interface in the file
1097 lib/silcutil/silchashtable.h.
1099 * Fixed minor bugs and changed it to use some of the new
1100 hash table functions in lib/silccore/idcache.c
1102 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added new function silc_hash_table_find_all to return all keys
1105 in the hash table by the specified key. As the hash table is
1106 collision resistant it also makes it possible to have several
1107 duplicate keys in the hash table. This function may be used to
1108 find all of the keys from the hash.
1110 Added user_context arguments to the SilcHashFunction,
1111 SilcHashCompare and SilcHashDestructor to deliver user specified
1114 Added new fuctions silc_hash_table_find[_all]_ext to do
1115 extended lookup with specified hash and compare functions and
1116 specified user contexts.
1118 Added new function silc_hash_table_add_ext to add the key
1119 with specified hash function and user context.
1121 Added new function silc_hash_table_foreach to traverse all
1122 entrys in the hash table. Added SilcHashForeach callback
1125 Added new function silc_hash_table_del_by_context to delete
1126 the entry only if the context associated with the key matches.
1128 Affected files are lib/silcutil/silchashtable.[ch].
1130 * Removed silc_hash_[server/client/channel]_id and added just
1131 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1132 silc_hash_id_compare to compare two ID's using as the hash table
1133 comparison function. Added also silc_hash_data to hash
1134 binary data and silc_hash_data_compare to compare it.
1136 * Removed silc_idlist_find_client_by_hash as it is not needed
1137 anymore. Affected file silcd/idlist.[ch].
1139 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1140 to use internally the SilcHashTable. The new ID Cache is a lot
1141 faster than the old one. Some of the ID Cache interface was also
1142 rewritten and obsolete and stupid functions were removed.
1144 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Added entry_count field to the SilcHashTable to keep the number
1147 of the entries in the table. Implemented the function
1148 silc_hash_table_rehash. Added new function
1149 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1151 Fixed a minor bug in silc_hash_table_free.
1153 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1154 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1155 into the lib/silcutil/silcutil.[ch].
1157 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Implemented a collision resistant hash table into the
1160 lib/silcutil/silchashtable[ch]. See the header and the source
1161 for the SilcHashTable API.
1163 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1165 * Merged dotconf version 1.0.2 into lib/dotconf.
1167 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Do not compile anything in lib/silcsim/* if the SIM support
1170 is not enabled. The tree should now compile without problems
1173 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Compiled the SILC under cygwin. Compiled and tested briefly
1176 without problems. More tests needed. The SIMs didn't compile
1179 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1181 * Fixed possible crash in silc_get_username in the
1182 lib/silcutil/silcutil.c.
1184 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Fixed a va_arg in silc/client_ops.c.
1188 * Oops, RC5 routines were named AES and caused some problems
1189 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1191 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Added new SilcIDIP structure into the lib/silccore/id.h and
1194 replaced the old `ip' fields from all SILC ID's to that type.
1195 This is a step towards IPv6 support.
1197 The silc_id_get_len takes now the ID as an extra argument.
1198 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1199 both IPv4 and IPv6 based ID's.
1201 The affected files are lib/silccore/id.[ch] and other files
1202 around the tree using these routines.
1204 * Removed the ID length arguments in server from various
1205 silc_server_send_notify_* routines -> they are not needed
1208 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Fixed memory leak in silc_encode_pem_file in the file
1211 lib/silcutil/silcutil.c.
1213 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Check minor version as well in the SKE. Affected files are
1216 silcd/protocol.c and lib/silcclient/protocol.c.
1218 * Added --identifier option to the server so that an identifier
1219 can be when creating the public key for the server. Affected
1220 file is silcd/silcd.c.
1222 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1223 lib/silccrypt/silcpkcs.c.
1225 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1227 * Register default ciphers and stuff when using -C option with
1228 the server. Affected file sildc/silcd.c.
1230 * Put back the servers public key filename format, it is better
1231 than the new one. For now, the client keys are saved with the
1232 new filename format. The affected file silc/client_ops.c.
1234 * Implemented the Cipher API for the rest of the ciphers that
1235 did not implement it or implemented it the wrong way.
1237 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Register default ciphers and stuff when using the -S option
1240 in the client. Affected file silc/silc.c. Same also when
1241 creating new key pair with -C option.
1243 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Fixed the silc_verify_public_key client operation function to
1246 save the public keys differently. The fingerprint is now
1247 used as filename and not the hostname. This way also the
1248 client keys are saved uniquely and not with hostnames. The
1249 affected file is silc/client_ops.c.
1251 * Trimmed the silc_hash_fingerprint function to remove extra
1252 whitespaces from the end of the fingerprint. The affected
1253 file is lib/silccrypt/silchash.c.
1257 * Added silc_cipher_register_default function to register all
1258 default ciphers. It can be used when configuration files
1259 does not exist and the application does not want any specific
1260 ciphers in any specific order.
1262 The SilcDList is now used as silc_cipher_list dynamically
1263 allocated cipher list. Removed the static list all together
1264 and now all ciphers must be allocated to the dynamic list.
1265 The silc_cipher_alloc routine was changed to check only the
1268 All silc_cipher_* routines that used to return int returns
1271 The affected files lib/silccrypt/silccrypt.[ch].
1273 * The same thing was done to silc_hash_* as for silc_cipher_*
1274 routines. Affected files lib/silccrypt/silchash.[ch].
1276 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1277 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1278 Added also silc_pkcs_[un]register[_default] functions.
1279 Removed the data_context from the PKCS API.
1281 * Added silc_hmac_register_default function to register default
1282 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1283 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1284 to unregister all hmacs at once.
1286 * Register the default ciphers, hash functions, PKCSs and HMACs
1287 if client's configuration file does not exist. The affected
1290 * The client did not load the hash functions from the SIM
1291 modules at all. Added support for this. Affected file is
1292 silc/clientconfig.c.
1294 * When decoding public key with silc_pkcs_public_key_decode, check
1295 the supported algorithm only if PKCS are registered. Affected
1296 file lib/silccrypt/silcpkcs.c. The same was done with the
1297 silc_pkcs_private_key_decode.
1299 * Fixed the SILC List routines to keep the list always in order.
1300 It used to change the list's order when traversing the list but
1301 not it preserves the order. Affected file lib/trq/silclist.h.
1303 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Added the client library to use the SilcSocketConnection's
1306 reference counter (by silc_socket_dup) to prevent the bug that
1307 the socket object may be freed underneath async operation.
1309 * The name resolv library checking fixes in the configure.in.pre.
1312 * Created new version of the protocol drafts for future
1313 development. The -03 drafts are the ones that will be changed
1314 in the trunk now and the -02 will remain as they are.
1316 * Send list of CUMODE notifys to the router when announcing
1317 the channel users to the router. Affected file silcd/server.c.
1318 If the router receiving channel founder CUMODE for a channel
1319 that already has channel founder it will send CUMODE notify
1320 to the sender to remove the channel founder rights from the
1321 announced client. Affected file silcd/packet_receive.c.
1323 * The CUMODE notify may now use Server ID as well as the entity
1324 who changes the mode. Updated protocool specs.
1326 * Updated INSTALL and README files.
1328 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * New web pages in the http://silc.pspt.fi. The pages was
1335 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Implemented the [DenyConnectin] config section in the server.
1338 Added silc_server_config_denied_conn to check whether incoming
1339 connection is denied. Affected file silcd/serverconfig.[ch].
1341 * Do not check the ports when checking the incoming configuration
1342 data if the port is 0, meaning any. Affected file is
1343 silcd/serverconfig.c.
1345 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Fixed buffer overflow in silc_string_compare in the file
1348 lib/silcutil/silcutil.c.
1350 * Fixed double free in silc_server_command_leave in the file
1353 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Fixed the version checking in the server. Affected file is
1358 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1360 * Fixed the configuration data fetching when accepting new
1361 connections in the server. Affected file silcd/server.c.
1363 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Added `sender_entry' argument to the function
1366 silc_server_packet_relay_to_channel so that we can check
1367 whether some destination actually belongs to the same route
1368 the sender belongs (ie, we must not resend the packet to the
1369 sender). Affected file silcd/packet_send.[ch].
1371 * Added `servername' field to the SilcClientEntry in the server
1372 to hold the name of the server where client is from. Affected
1373 file is silcd/idlist.h.
1375 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Moved the channel message encrypting in the router betwen
1378 router connections from silc_server_channel_message to the
1379 silc_server_packet_relay_to_channel since we want to check
1380 whether we have anybody channel before encrypting anything.
1381 Affected files silcd/packet_[receive/send].c.
1383 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Fixed the [AdminConnection] server config section to support
1386 multiple entries. Affected file silcd/serverconfig.c.
1388 * Added support into the server to check the validity of the
1389 incoming connection before executing any KE or authentication
1392 * The connection configuration is now saved to the KE and
1393 connection auth protocol contexts and not fetched anymore in
1394 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1396 * The local hosts listenning address and port is also resolved
1397 now when starting the server. We want to have the socket object
1398 to include the real address and port for the listener. Added
1399 new function silc_net_check_local_by_sock into the files
1400 lib/silcutil/silcnet.[ch].
1402 * Fixed a broadcast bug in server -> do not broadcast if we
1405 * Fixed a routing bug. Do not route broadcast packets ever.
1406 Broadcast packets must be processed always and not routed since
1407 they may be destined to some other host than yourself and thus
1408 would get routed without no good reason. Affected file is
1411 * Added function silc_server_config_is_primary_route to check
1412 whether primary router connection has been configured (a router
1413 configuration that we are initiating). If there is not, we
1414 will assume that there is only two routers in the SILC network
1415 and we will use the incoming router connection as our primary
1416 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1418 * Changed the order of the broadcasting. Broadcast _after_ the
1419 packet has been processed not before. Affected file is
1422 * Fixed a [ClientConnection] parsing bug. The port was never
1423 parsed correctly thus resulting to port 0. Affected file
1424 silcd/serverconfig.c.
1426 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1427 argument and did not set the broadcast packet flag. Affected
1428 file silcd/packet_send.c. Fixed same bug in the function
1429 silc_server_send_notify as well.
1431 * If we receive NEW_ID packet for our own ID in the server, ignore
1434 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Removed the nickname from the Private Message Payload.
1439 Updated the code and the protocol specs.
1441 * Updated protocol specs for submitting to the IETF.
1443 * Tweaked the Random Number Generator a bit. Affected file
1444 lib/silccrypt/silcrng.c. Exported a new function
1445 silc_rng_[global]_add_noise which can be used to add more
1448 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Do not parse packets with different timeout when protocol
1451 is active -> may cause problem with rekey. Affected file
1454 * When server receives signoff notify it must not create
1455 new channel key if the client is on any channels since the
1456 sender of the signoff notify will create it.
1458 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Added printing of error messages during SKE protocol from the
1461 failure packet sent by server during SKE. Affected file
1464 * Removed the client's failure_callback handling with timeout
1465 and handle it immediately when received.
1467 * The SKE library returned wrong type in SUCCESS and FAILURE
1468 packets. They must be 32 bit MSB not 16 bit MSB.
1470 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Ok, rewrote the logic of the re-key and now it seems to work.
1473 I tested it on high traffic with frequent re-keys without
1474 problems. Added hmac_receive (and renamed hmac to hmac_send)
1475 in SilcClientConnection in lib/silcclient/client.h and
1476 in SilcIDListData in silcd/idlist.h. Also, removed the
1477 SilcPacketParserContext's cipher and hmac fields as they are
1478 not needed anymore and actually caused some problems when
1479 the ciphers and hmac's changed underneath the packet parser.
1481 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * If re-key protocol is active then process the incoming packets
1484 synchronously since we must assure that icoming packets encrypted
1485 with the old key is processed before the new keys is set to
1486 use. This is true other packets than for REKEY packets.
1487 Affected file silcd/server.c. The same was done to client library
1488 as well, affected file lib/silcclient/client.c.
1490 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * Fixed bug in client and server to accept the force send if
1493 the packet is send from silc_[server/client]_packet_process
1494 function. Otherwise the packets are never delivered, oops.
1496 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1498 * Disable force sending of packets when REKEY protocol is active.
1499 We must assure that no packet is sent directly when rekey is
1500 performed. All packets must be sent through packet queue.
1501 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1502 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1503 function is silc_[server/client]_packet_send_real to check
1506 * Replaced the SIM paths from example config files to
1507 /usr/local/modules. Also, make install creates now
1508 /usr/local/silc/logs directory to hold all the SILC server
1511 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Made the configure.in.pre work on Solaris. Patch by salo.
1515 * Made all ciphers compatible with non-x86 machines. Defined
1516 CBC mode macros into lib/silccrypt/ciphers_def.h.
1518 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * Fixed the make install.
1522 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1524 * When MAC computation fails the silc_packet_decrypt returned 0
1525 even though it was supposed to return -1. Fixed this. The
1526 affected file is lib/silccore/silcpacket.c.
1528 * Do not replace the config files in /etc/silc (in make install)
1529 if they already exist. Affected file ./Makefile.am.
1531 * Do not send re-key packets immediately but through packet queue.
1532 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1534 * Changed silc_net_check_host_by_sock to return FALSE if the
1535 IP/DNS could not be resolved. Though, it returns the IP address
1536 now even if it could not resolve it (but returns also FALSE).
1537 Affected file lib/silcutil/silcnet.[ch].
1539 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * Added silc_pkcs_decode_identifier to decode the public key's
1542 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1543 Added also silc_pkcs_free_identifier. Added also new context
1544 SilcPublicKeyIdentifier.
1546 * Added -S option to the silc client. It is used to dump the
1547 contents of the specified public key file.
1549 * Changed the PKCS api to return the public key length when
1550 setting the public key.
1552 * Fixed a fatal bug in the public and private key file loading.
1553 Affected file lib/silccrypt/silcpkcs.c.
1555 * Execute the packet parsing for client with zero (0) timeout
1556 if the protocol is active. Affected file silcd/server.c.
1558 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Made the key generation options to the silcd program. Added
1561 -C option, equivalent to client's option.
1563 * Added new [ServerKeys] config section to the server. It
1564 configures the server's public and private key.
1566 * Defined generic Public Key Payload into the protocol
1567 specification to send specific type of public keys and
1570 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1571 public key or certificate.
1573 * Implemented the GETKEY command to the server and to the
1574 client library and on user interface.
1576 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Made preliminary `make install' work.
1580 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Added SilcServerRekey context into silcd/idlist.h.
1584 * Added the PFS support as defined in the specification to the
1585 SKE protocol. Affected files lib/silcske/*.c.
1587 * Added `ske_group' field to the SilcServerRekey context to hold
1588 the number of the SKE group that is used with PFS in re-key.
1589 Affected file silcd/idlist.h.
1591 * Added PFS re-key support to the server. Affected file is
1594 * Added silc_protocol_cancel to cancel execution of the next
1595 state of the protocol. Affected file is
1596 lib/silccore/silcprotocol.[ch].
1598 * Added the re-key support with and without PFS to the client
1599 library. Re-key is performed once in an hour, by default.
1601 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1602 Added silc_client_rekey_callback and silc_client_rekey_final.
1603 Affected files are lib/silcclient/protocol.[ch] and
1604 lib/silcclient/client.[ch].
1606 * Removed the `hmac_key' and `hmac_key_len' fields from the
1607 SilcClientConnection structure; not needed. Affected file is
1608 lib/silcclient/client.h.
1612 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Do not ask whether user wants to use the negotiated private key
1615 for private messages, just use it. Affected file is
1616 silc/local_command.c.
1618 * Added `send_enc_key' and `enc_key_len' fields to the
1619 SilcIDListData structure since they are needed in the re-key
1620 phase. Affected file is silcd/idlist.[ch].
1622 * Implemented the simple re-key protocol into the server.
1623 Affected files silcd/server.c and silcd/protocol.[ch]. The
1624 re-key will be performed once in an hour, by default.
1626 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1627 Added silc_server_rekey, silc_server_rekey_callback and
1628 silc_server_rekey_final.
1630 * Removed Tunneled flag from the protocol. Updated the code
1631 and the specifications.
1633 * Adde `pfs' field to the SilcIDListData to indicate whether
1634 the PFS is to be performed in the re-key. Affected file is
1637 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1640 int64 of at least the xintXX size. If void * is less that 4
1641 bytes uint32 * will be used. Defined bool as boolean.
1643 * Changed _ALL_ unsigned long and unsigned int to uint32,
1644 unsgined short to uint16 in the source tree.
1646 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1647 not handle clients that has entry->data.registered == FALSE.
1648 They are not in the network anymore. Affected file is
1651 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Implemented the sending of the SERVER_SIGNOFF notify in the
1654 server. Affected file is silcd/server.c.
1656 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1657 Added also silc_notify_payload_encode_args into the
1658 lib/silccore/silcnotify.[ch].
1660 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1661 Affected file silcd/packet_receive.c.
1663 * Implemented the SERVER_SIGNOFF notify handling in the client
1664 library. Affected file lib/silcclient/client_notify.c. Also,
1665 implemnted the printing of the SERVER_SIGNOFF info to the
1666 application. Affected file silc/client_ops.c.
1668 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1669 if the deleting was successful. Affected file silcd/idlist.[ch].
1671 * Added support for public key authentication in the connection
1672 authentication protocol in the client library. Affected file
1673 lib/silcclient/protocol.c.
1675 * Changed the server's silc_idlist_get_clients_by_* interface
1676 to support already allocated array so that new entries may be
1677 added to pre-allocated array. Affected file silcd/idlist.[ch].
1678 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1679 and command replies.
1681 * All command reply functions in the server now calls the
1682 pending command callback even if error occured. This way the
1683 error will be delivered to the client as well. Affected files
1684 silcd/command.c and silcd/command_reply.c.
1686 * Fixed INFO command to return local server's info if no server
1687 was provided. Affected file lib/silcclient/command.c.
1689 * Removed RESTART command for good. Updated the code and the
1692 * Rewrote parts of the task system. It is a bit simpler now.
1693 Removed unsued task priorities. The affected files are
1694 lib/silcutil/silctask.[ch].
1696 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * Moved the USERS printing from the library to the application.
1699 Affected files lib/silcclient/command.c and silc/client_ops.c.
1701 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1705 * Added channel key re-key support. The re-key is perfomed
1706 only by the router and is done once in an hour. Added `rekey'
1707 field to the SilcChannelEntry in the server. Affected files
1708 silcd/server.c and silcd/idlist.h.
1710 * Added silc_task_unregister_by_context into the file
1711 lib/silcutil/silctask.[ch].
1713 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Added SILC_UMODE_GONE mode to indicate when the client is not
1716 present in the SILC network. Added also support to the local
1717 command AWAY that will set this mode. Added support of showing
1718 "xxx is gone" in WHOIS command. The USERS command shows the
1719 gone status as well.
1721 * Fixed setting server and router operator privileges in the
1722 server's UMODE command. Affected file silcd/command.c.
1724 * Merged the SKE KE1 and KE2 payloads into one payload. The
1725 new KE payload is equivalent to the old KE2 payload.
1727 Cleaned up the SKE Start Payload parsing. It now uses the
1728 simple buffer unformatting to do the parsing. A lot faster
1731 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1732 to the SKE that is used to indicate whether both of the SKE
1733 parties should perform authentication. By default only the
1734 responder performs authentication. By setting this flag also
1735 the initiator must do authentication. By default it is unset
1736 since in normal SKE case, client to server connection, only
1737 the responder should do authentication. When doing SKE between
1738 two clients both should perform authentication. Updated the
1739 code and the protocol specs.
1741 * A little fix to IDENTIFY command in the server. Search the
1742 client first by hash not nickname. Affected file is
1745 * Fixed the silc_client_close_connection to support closing
1746 the client to client connections wihtout deleting too much
1747 data. Affected file lib/silcclient/client.c.
1749 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1750 are received if protocol used to be active but is not anymore
1751 the application would crash due to NULL pointer dereference.
1752 Affected files silcd/server.c and lib/silcclient/client.c.
1754 * Added `hash' field to the SilcClientConnection to include
1755 the hash function negotiated in the SKE protocol.
1757 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1758 to set the channel founder authentication data. A client can
1759 claim the founder rights later by providing the authentication
1760 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1761 This way the channel founder can regain the channel founder
1762 privileges even it is left the channel. This works only on
1763 local server and the client must be connected to the same
1764 server to be able to regain the founder rights. Updated the
1765 protocol specs accordingly.
1767 Added support to the CMODE command in the client to set the
1768 founder auth data. Read the README to see how to set it.
1770 Added support to the CUMODE command to claim the founder
1771 rights. Read the README to see how to do it.
1773 Added support for the founder authentication to the Channel
1774 Entry in the server. Affected file silcd/idlist.h.
1776 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1777 server's CMODE command. Affected file silcd/command.c.
1779 * Added the following new functions into lib/silccore/silcauth.[ch]:
1780 silc_auth_get_method and silc_auth_get_data.
1782 * The server now saves the remote hosts public key to the
1783 SilcIDListData pointer. Affected file silcd/protocol.c.
1785 * The normal server now does not remove the channel entry from
1786 the cache if the founder authentication data is set. It used
1787 to remove it if the founder was the last one on the channel on
1788 the server and left the channel. The auth data is saved and
1789 if the channel is re-joined later the old entry is used with
1790 the old auth data. Affected files silcd/command_reply.c and
1793 * Removed the `pkcs' field from the SilcIDListData structure
1794 in the server; it is not used. Affected file silcd/idlist.h.
1796 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Fixed packet processing on slow links. Partial packets were
1799 never re-processed because the incoming data buffer was cleared
1800 by the application. Application must not directly clear the
1801 sock->inbuf, the packet processing routines handle it. Fixed
1802 this in client library and in server.
1804 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Fixed the WHOIS and IDENTIFY send reply function to really
1807 check whether to send list or just one entry. Affected file
1810 * Cleaned up the LEAVE command's channel key distribution. The
1811 affected file silcd/command.c.
1813 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1814 can enforce the channel mode as well. In that case the ID
1815 includes the ID of the server. The code now enforces the
1816 mode change if the router have different mode than the server.
1818 * The notify client operation with CMODE_CHANGE notify can now
1819 return NULL client_entry pointer if the CMODE was not changed
1820 by client. Application must check for this.
1822 * Added <Server ID> argument to INFO command to support server
1823 info fetching by Server ID.
1825 * Added silc_server_announce_get_channel_users to get assembled
1826 packets of channel users of the specified channel. Affected
1827 file silcd/server.[ch].
1829 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1830 was freed underneath the ID Cache.
1832 * Re-announce clients when the server received CHANNEL_CHANGE
1833 notify from the router. Affected file silcd/packet_send.c.
1835 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1838 crashed since it did not handle the fact that there is no cipher
1839 called "3" and didn't check the error condition. Now fixed.
1841 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1842 flag. It can be used to send message requests.
1844 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * Implemented the RESTART command in the client.
1848 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1849 notice type messages. Added notice printing to the user
1852 * The channel keys are not re-generated if the channel's mode
1853 is PRIVKEY, ie private key on the channel exists. Affected
1854 files silcd/server.c and silcd/command.c.
1856 * Fixed a little bug in channel message delivery when channel
1857 private keys are set in the server. Affected file is
1858 silcd/packet_send.c.
1860 * Changed the setting on channel->on_channel = TRUE from the
1861 silc_client_save_channel_key to the JOIN command reply. The
1862 key payload is not received if the private channel key is set.
1863 Affected file lib/silcclient/command_reply.c and the
1864 lib/silcclient/client_channel.c.
1866 * When the CMODE_CHANGE notify is sent and the channel private
1867 key mode is removed the channel key must be re-generated in
1868 other cells as well. Added this support for the router in the
1869 silcd/packet_receive.c.
1871 * Added new local command NOTICE to send notice message on
1872 channel. Affected file silc/local_command.[ch].
1874 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Added new local command ME to the client. It is used to send
1877 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1878 some action. Affected file silc/local_command.[ch].
1880 * Changed channel_message and private_message client operations
1881 to deliver the message flags to the application. Added also
1882 the `flags' arguments to the silc_client_send_channel_message
1883 and silc_client_send_private_message functions. Affected file
1886 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Redefined the Private Message Payload to support private message
1889 keys and to support the new private message flags. Updated
1890 the protocol specs. Flags makes it possible to have for example
1891 CTCP style messages.
1893 * Added new type SilcPrivateMessagePayload and defined an API
1894 for it in the lib/silcclient/silcprivate.[ch].
1896 * Tested private message private keys successfully. Tested the
1897 private message key set, unset and list commands with the new
1900 * Redefined the Channel Message Payload to include the channel
1901 message flags (equal with private message flags) to support
1902 for example CTCP style messages.
1904 * Defined some of the message (for channel and private message)
1905 flags. Updated the protocol specs and added the flags to the
1906 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1908 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Added SilcKeyAgreementStatus type to the key agreement routines
1911 to indicate the current status and error if one occured.
1912 The status types are defined in the lib/silcclient/silcapi.h.
1914 * Added new local command KEY that is used to set and unset private
1915 keys for channels, set and unset private keys for private messages
1916 with remote clients and to send key agreement requests and
1917 negotiate the key agreement protocol with remote client. The
1918 key agreement is supported only to negotiate private message keys,
1919 it currently cannot be used to negotiate private keys for channels,
1920 as it is not convenient for that purpose.
1922 * Fixed a minor pending callback setting bug in the function
1923 silc_client_get_client_by_id_resolve, now the function works.
1924 Affected file lib/silcclient/idlist.c.
1926 * Added function silc_net_get_local_port to get local bound
1927 port by socket. Added to lib/silcutil/silcnet.[ch].
1929 * Added `sockets' and `sockets_count' fields to the SilcClient
1930 object. They hold the sockets of the listenning sockets in
1931 the client. Listenning sockets may be for example the key
1932 agreement server. Affected file lib/silcclient/client.[ch].
1933 Added functions the silc_client_add_socket and the
1934 silc_client_del_socket. They are exported to the application
1937 * Added ~./silc/clientkeys to support other client's public keys.
1939 * Renamed verify_server_key client operation to verify_public_key
1940 and added one argument to indicate the type of the connection
1941 (server, client etc.).
1943 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Added silc_server_connection_auth_request to handle the
1946 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1947 silcd/packet_receive.[ch].
1949 * Added silc_server_send_connection_auth_request into the
1950 silcd/packet_send.c to send the connection auth request packet.
1952 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1955 * Fixed the public key authentication in responder side in the
1956 server. The `auth_data' pointer includes the SilcPublicKey
1957 not the path to the public key. Affected file silcd/protocol.c.
1959 * Implemented the public key authentication in the initiator side
1960 in the server. Affected file silcd/protocol.c.
1962 * Removed the [RedirectClient] config section from the server
1963 configuration. Is not needed and I don't want to implement it.
1965 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Cleaned up the CMODE command in the server. It now works
1968 correctly and supports all the modes defined in the protocol.
1969 Affected file is silcd/command.c.
1971 * Added `hmac_name' field to the SilcChannelEntry in the server
1972 to hold the default HMAC of the channel. It can be set when
1973 creating the channel (with JOIN command). Affected files
1976 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1977 type to indicate the change of the current cipher and hmac
1978 on the channel. Client can safely ignore the <cipher> argument
1979 (if it chooses to do so) since the CHANNEL_KEY packet will
1980 force the channel key change anyway. The <hmac> argument is
1981 important since the client is responsible of setting the new
1982 HMAC and the hmac key into use.
1984 * Fixed the CMODE command in the client library as well.
1986 * Tested CMODE command in router environment successfully.
1988 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Show the version of the remote client (or server) when connecting
1991 to the server. It is logged to the log file. Affected file
1992 is silcd/protocol.c.
1994 * Fixed the KILLED notify handling in the client library. The
1995 client must be removed from all channels when receiving the
1998 Also, do not remove the client entry when giving the KILL
1999 command but when the KILLED notify is received.
2001 * Removed silc_idlist_find_client_by_nickname from the server.
2002 Not needed anymore. Affected files silcd/idlist.[ch].
2004 * Implemented the CHANNEL_CHANGE notify type handling to the
2005 server. Affected file silcd/server.c.
2009 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Added silc_server_send_notify_invite to send the INVITE
2012 notify between routers.
2014 * Implemented the INVITE command correctly to the server.
2016 * Implemented the INVITE notify type handling in the server.
2018 * Implemented the INVITE command to the client library and on the
2021 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Added function silc_server_get_client_resolve to find the
2024 client entry by ID from all ID lists and then resolve it
2025 (using WHOIS) if it cannot be found. Affected file is
2028 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Implemented the BAN command to the client library.
2032 * The JOIN command in the server now checks the invite list
2035 * Changed the silc_command_reply_payload_encode_va and the
2036 silc_command_payload_encode_va to support that if argument is
2037 NULL it ignores and checks the next argument. Affected file
2038 lib/silccore/silccommand.c.
2040 * Added silc_server_send_notify_ban to send the BAN notify
2041 type between routers.
2043 * Chaned the silc_notify_payload_encode to support that if
2044 argument is NULL it ignores and checks the next argument.
2045 Affected file lib/silccore/silcnotify.c.
2047 * Tested ban lists in router environment successfully.
2049 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2051 * Implemented BAN command to the server, in silcd/command.[ch].
2053 * Removed the BAN and INVITE_LIST modes from the CMODE command
2056 * Added function silc_string_match to regex match two strings.
2057 Affected files lib/silcutil/silcutil.[ch].
2059 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Redefined parts of the SilcChannelEntry in the server to support
2062 the new ban and invite lists.
2064 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Redefined the INVITE command. The same command can be used to
2067 invite individuals to the channel but also to manage the invite
2068 list of the channel (to add to and remove from the invite list).
2069 Updated the protocol specs.
2071 * Added new command SILC_COMMAND_BAN that can be used to manage
2072 the ban list of the channel. Updated the protocol specs.
2074 * Removed the channel modes: the SILC_CMODE_BAN and the
2075 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2076 in the CMODE command. The equivalent features are now available
2077 using INVITE and BAN commands. Updated the protocol specs.
2079 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2080 in the network about change in the current ban list. The notify
2081 type is not used by the client.
2083 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2084 support the invite lists.
2086 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Added new function silc_string_regexify that converts string
2089 including wildcard characters into regex string that can
2090 be used by the GNU regex library. Added into the file
2091 lib/silcutil/silcutil.[ch].
2093 Added silc_string_regex_combine to combine to regex strings
2094 into one so that they can be used as one regex string by
2095 the GNU regex library. Added into the file
2096 lib/silcutil/silcutil.[ch].
2098 Added silc_string_regex_match to match two strings. It returns
2099 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2101 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Imported GNU regex to the soruce tree into lib/contrib.
2104 Fixed some compiler warning from the regex.c.
2106 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Fixed MOTD command in the server to work in router environment.
2110 * Fixed the MOTD command in the client library to support
2111 the server argument in the command.
2113 * Added `nickname_len' argument to the silc_idlist_add_client
2114 in the server, as the `nickname' argument may be binary data
2117 * Added silc_idlist_get_channels to return all channels from
2120 * Implemented LIST command to the server. Affected file is
2123 * Implemented the LIST command to the client library and on the
2126 * Added [<user count>] argument to the LIST command reply.
2127 With private channels the user count is not shown.
2129 * Updated TODO and README.
2131 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * The client entry's data.registered must be TRUE even with
2134 global client entry on global client list. The data.registered
2135 is used to check whether the client is anymore in the network,
2136 for example with WHOWAS command so it must be valid.
2138 * Fixed the WHOWAS command in the server. It now actually works
2139 in router environment. Added function into silcd/command_reply.c
2140 silc_server_command_reply_whowas_save.
2142 * Added silc_idlist_purge function to the silcd/idlist.c
2143 to periodically purge the ID Cache.
2145 * Fixed INFO command in the server. It works now in router
2146 environment. Added <server name> argument to the INFO command
2147 reply. Updated the protocol specs.
2149 * Fixed minor bug in silc_idcache_purge to not purge if the
2150 expire value is zero.
2152 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2153 they were buggy because of the WHOWAS information.
2155 * Fixed local command MSG to handle the async resolving of
2156 the remote client properly. It used to fail the first MSG.
2157 Affected file silc/local_command.c.
2159 * Added `data_len' field to SilcIDCache context.
2161 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Update TODO. Todo in commands in the server.
2165 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2168 used by routers as broadcast packet to inform other routers
2169 about the changed user mode.
2171 Implemented the notify handling in the server. Affected file is
2172 silcd/packet_receive.c. Added the function
2173 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2175 * Added new generic Channel Payload and deprecated the New Channel
2176 Payload. The New Channel Payload is now the generic Channel
2179 * Added new argument `mode' to the silc_server_send_new_channel
2180 as it is required in the Channel Payload now.
2182 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2183 and created a new and real SilChannelPayload to represent the
2184 new generic Channel Payload. Implemented the encode/decode
2185 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2187 * Added silc_server_get_client_channel_list to return the list
2188 of channels the client has joined for WHOIS command reply.
2189 Affected file silcd/server.[ch].
2191 * Implemented the channel list sending in the WHOIS command reply
2192 in server and in the client.
2194 Implemented the channel list displaying on the user interface
2195 as well. Affected file silc/client_ops.c.
2197 * Added silc_channel_payload_parse_list to parse list of Channel
2198 Payloads. It returns SilcDList list of SilcChannelPayloads.
2199 Client for example can use this function to parse the list of
2200 channels it receives in the WHOIS command reply. The caller
2201 must free the list by calling silc_channel_payload_list_free.
2202 Affected files lib/silccore/silcchannel.[ch].
2204 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Added one new argument <user mode> to the WHOIS command reply
2207 to return the mode of the user in SILC. Updated the protocol
2210 Implemented it to the server and client.
2212 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Fixed the mode printing on the user interface on joining.
2215 Affected file silc/client_ops.c.
2217 * Implemented the UMODE command and user modes in general to the
2218 client library and to the user interface.
2220 * Implemented the UMODE command to the server.
2222 * The server now sends UNKNOWN_COMMAND error status if client sends
2223 unknown command. Affected file silcd/command.c.
2225 * All server commands now handle the command identifier the right
2226 way when sending the command reply to the client. The client can
2227 use to identify the command replies with the identifier.
2229 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Added silc_server_get_client_route to resolve the route to
2232 the client indicated by the client ID. Affected file is
2235 * Added silc_server_relay_packet as general function to relay
2236 packet to arbitrary destination. This deprecates functions
2237 like _send_private_message_key, _relay_notify etc. Affected
2238 file is silcd/packet_send.[ch].
2240 Removed silc_server_send_key_agreement,
2241 silc_server_send_private_message_key and
2242 silc_server_packet_relay_notify functions from the file
2243 silcd/packet_send.[ch].
2247 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2248 server. Affected file silcd/packet_receive.[ch].
2250 * Implemented the KILL command to the client. Implemented the
2251 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2252 Affected files lib/silcclient/command[_reply].c and
2253 lib/silcclient/client_notify.c. Implemented the KILL notify
2254 printing in the user inteface.
2256 * Fixed a lot silc_parse_nick memory leaks from the client
2257 library in the file lib/silcclient/command.c.
2259 * Changed the silc_server_send_notify_on_channels's `sender'
2260 argument from SilcSocketConnection to SilcClientEntry to
2261 check the sender as entry and not as connection object and not
2262 to send to the client provided as argument. The affected file
2263 is silcd/packet_send.[ch].
2265 * The notify packets that are destined directly to the client used
2266 to not to be processed by the server. Now changed that and the
2267 server processes all notify packets. After relaying the packet
2268 to the client the notify packet is processed in the server.
2270 * The silc_server_free_client_data now checks whether there is
2271 pending outgoing traffic for the client and purges the data to
2272 the network before removing the client entry.
2274 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2277 an client is killed from the SILC Network. Updated the protocol
2280 Added new function silc_server_send_notify_killed to the
2281 silcd/packet_send.[ch].
2283 * Added function silc_server_packet_relay_notify to relay notify
2284 packets that are destined directly to a client. In this case
2285 the server does not process the notify packets but merely relays
2286 it to the client. Affected file silcd/packet_send.[ch].
2288 Added also silc_server_packet_process_relay_notify to check
2289 whereto relay the notify. Affected file is
2290 silcd/packet_receive.[ch].
2292 * Implemented the KILL command to the server.
2296 * Added the backup schema desgined last fall to the protocol
2297 specs for everyone to see. The specification is in the
2298 *-spec-xx.txt draft and the packet type definitions for the
2299 backup routers is in *-pp-xx.txt draft. Thusly, added also
2300 new packet type SILC_PACKET_CELL_ROUTERS.
2302 * A big security problem in the implementation discovered. The
2303 signoff of an client did not cause new channel key generation
2304 which it of course should've done. The channel keys must be
2305 always re-generated when client leaves (or signoffs) the channel.
2306 The silc_server_remove_from_channels funtion now handles
2307 the channel key re-generation.
2309 * Added `sender' argument to the silc_server_send_notify_on_channels
2310 to not to send the client provided as argument. Affected file
2311 silcd/packet_send.[ch].
2313 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Implemented OPER and SILCOPER commands into the server and
2318 * Added silc_auth_verify and silc_auth_verify_data to verify
2319 the authentication directly from the authentication payload.
2320 It supports verifying both passphrase and public key based
2321 authentication. Affected file lib/silccore/silcauth.[ch].
2323 * Added `hash' field to the SilcIDListData structure. It is the
2324 hash negotiated in the SKE protocol. Affected file is
2327 * Slight redesigning of the SilcAuthPayload handling routines.
2328 Do not send SilcPKCS but SilcPublicKey as argument.
2330 * Implemented the public key authentication support to the
2331 serverconfig. The public key is loaded from the provided path
2332 and saved as authentication data to void * pointer. Thus,
2333 changed the unsigned char *auth_data to void *auth_data;
2335 * Fixed SHUTDOWN command to send the reply before the server
2336 is shutdown. :) Affected file silcd/command.c.
2338 * Fixed fatal bug in CONNECT command. The hostname was invalid
2339 memory and server crashed. Affected file silcd/command.c.
2341 * Fixed fatal bug in CLOSE command. The server_entry became
2342 invalid but was referenced later in the command. Affected file
2345 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Fixed fatal bug in failure packet handling. Server ignored
2348 the failure and thus crashed when it came.
2352 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2355 that the command may be executed only once in (about) 2 seconds.
2356 The old SILC_CF_LAG flag is same but allows command bursts up
2357 to five before limiting.
2359 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2360 server code. Various commands now includes the CF_LAG_STRICT
2361 flag to disallow any kind of miss-use of the command.
2363 * Fixed the silc_buffer_unformat to not to allocate any data
2364 if the length of the data is zero. It used to allocate the
2365 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2367 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Changed the format of AdminConnection configuration section
2370 in the server. Added username of the admin to the format.
2371 Affected files silcd/serverconfig.[ch].
2373 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2374 to return admin configuration data by host, username and/or
2377 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Implemented WHOWAS command to the server. Added the functions:
2381 silc_server_command_whowas_parse,
2382 silc_server_command_whowas_send_reply,
2383 silc_server_command_whowas_from_client and
2384 silc_server_command_whowas_from_server
2386 * Added <Client ID> argument to the WHOWAS command reply. Updated
2387 the protocol specs accordingly.
2389 * Implemented WHOWAS command and command_reply to the client
2392 Implemented the WHOWAS printing on the user interface.
2394 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Added new argument to the WHOWAS command reply, the real name.
2397 It is an optional argument. Updated the protocol specs.
2399 * Added SilcIDCacheDestructor callback that is registered when
2400 the SilcIDCache is allocated. The callback is called when
2401 an cache entry in the ID Cache expires, or is purged from the
2402 cache. Added into lib/silccore/idcache.[ch].
2404 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2405 to destruct the client entries when the cache entry expires.
2406 Other ID Cache's in server and in the client library ignores
2409 * If the ID Cache entry's `expire' field is zero then the entry
2410 never expires. Added boolean `expire' argument to the
2411 silc_idcache_add function in the lib/silccore/idcache.[ch].
2412 If it is TRUE the default expiry value is used.
2414 * Added silc_server_free_client_data_timeout that is registered
2415 when client disconnects. By default for 5 minutes we preserve
2416 the client entry for history - for WHOWAS command.
2418 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Added support to the server to enforce that commands are not
2421 executed more than once in 2 seconds. If server receives
2422 commands from client more frequently, timeout is registered
2423 to process the commands. Affected file silcd/command.c.
2424 Added new function silc_server_command_process_timeout.
2426 * Changed NICK_NOTIFY handling in client library to check that
2427 if the client's nickname was changed, so there is no need to
2428 resolve anything from the server.
2430 * Removed error printing from the WHOIS and IDENTIFY commands.
2431 If error occurs then it is ignored silently in the client library.
2432 The application, however, may map the received error to
2433 human readable error string. The application currently maps
2434 the NO_SUCH_NICKNAME error to string.
2436 * Made the command status message public to the application. Moved
2437 them from lib/silcclient/command_reply.c to
2438 lib/silcclient/command_reply.h. The application can map the
2439 received command status to the string with the
2440 silc_client_command_status_message function.
2442 * Added check to the server to check that client's ID is same
2443 as the Source ID in the packet the client sent. They must
2446 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Added dist-bzip hook to the Makefile.am to make bzip2
2449 compressed distributions.
2451 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Server now enforces the maximum length for the nickname and
2454 the channel as protocol specification dictates. 128 bytes for
2455 nickname and 256 bytes for channel name.
2457 * Moved the WHOIS printing to the application. The client libary
2458 does not print out the WHOIS information anymore, the application
2459 must do it. Renamed silc_client_command_reply_whois_print to
2460 the silc_client_command_reply_whois_save.
2462 The client's idle time is also sent to the application now, and
2463 the idle is shown on screen.
2465 * Added silc_client_command_reply_identify_save to save the
2466 received IDENTIFY entries.
2468 * Do not check for channel private keys in message sending and
2469 reception if the channel does not have the PRIVKEY mode set.
2470 Affected file lib/silclient/client_channel.c.
2472 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2475 just surfaced after chaning the JOIN procedure.
2477 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Added silc_client_get_clients_by_list to get client entries
2480 from Client ID list, that is returned for example by JOIN
2481 and USERS command replies. The application should use this
2482 function for example when JOIN command reply is received to
2483 resolve the clients already on the channel (library does not
2484 do that anymore as USERS command reply is not used in the JOIN
2485 procedure anymore). Affected files lib/silcclient/silcapi.h and
2486 lib/silcclient/idlist.c.
2488 * JOIN command reply and USERS command reply returns now SilcBuffer
2489 pointers instead of unsigned char pointers when returning
2490 the client list and mode list.
2492 * Added <Client ID> argument to the JOIN command reply, mainly
2493 for the server to identify for which client the command was
2494 originally sent. Updated protocol specs accordingly.
2496 * Added SilcDlist private_key pointer to the SilcChannelEntry
2497 in the client to support the channel private keys. Affected
2498 file is lib/silcclient/idlist.h.
2500 * Added SilcChannelPrivateKey argument to the function
2501 silc_client_send_channel_message so that application can choose
2502 to use specific private ke if it wants to. If it is not provided,
2503 the normal channel key is used, unless private keys are set.
2504 In this case the first (key that was added first) is used
2505 as the encryption key.
2507 * Implemented the support for channel private key handling.
2508 Implemented the following functions:
2510 silc_client_add_channel_private_key,
2511 silc_client_del_channel_private_keys,
2512 silc_client_del_channel_private_key,
2513 silc_client_list_channel_private_keys and
2514 silc_client_free_channel_private_keys
2516 Affected file lib/silcclient/client_channel.c.
2518 * Added the support for the private keys in the channel message
2519 sending and encryption and in the message reception and
2520 decryption. Affected funtions are
2521 silc_client_send_channel_message and silc_client_channel_message.
2523 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Added SKE's key verify callback to the client library's
2526 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2528 * Removed the statement that server (or router) must send USERS
2529 command reply when joining to the channel so that the client
2530 knows who are on the channel. Instead, the client list and
2531 client's mode list is now sent in the JOIN command reply to the
2532 client who joined channel. This is better solution.
2534 * Added function silc_server_get_users_on_channel and function
2535 silc_server_save_users_on_channel to the silcd/server.[ch].
2537 * Removed function silc_server_command_send_users from the
2540 * Do not show topic on the client library anymore. The topic is
2541 sent in the command reply notify to the application and the
2542 application must show the topic now.
2544 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Added client searching by nickname hash into the IDENTIFY and
2547 WHOIS commands in the server as they were clearly missing from
2548 them. Affected file is silcd/command.c.
2550 * Fixed a bug in private message receiving in the client library.
2551 The remote ID was freed and it wasn't supposed, now it is
2554 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Minor fix to the channel payload; allocate the data area, as it
2557 needs to be of specific length.
2559 * If the key agreement port is zero then the operating
2560 system will define the bound port. Affected files are
2561 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2563 * Added new function silc_channel_payload_decrypt into the file
2564 lib/silccore/silcchannel.[ch].
2566 * Moved the channel message etc, check from silc_packet_decrypt
2567 to applications. The library calls now a generic
2568 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2569 when the packet is either normal or special. This was done to
2570 allow more wide range of checking that was not allowed when
2571 the code was in library. Now applications can do virtually any
2572 checks to the packet and return to the library the decision how
2573 the packet should be processed. Affected files are
2574 lib/silccore/silcpacket.[ch].
2576 Added silc_server_packet_decrypt_check to the server and
2577 silc_client_packet_decrypt_check to the client library.
2579 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2580 to send with specified source and destination information.
2582 * Channel message delivery between routers was broken after the
2583 channel key distribution was fixed earlier. The channel key
2584 was used be to distributed to other routers as well which is not
2585 allowed by the protocol. Now this is fixed and channel keys
2586 really are cell specific and the channel message delivery between
2587 routers comply with the protocol specification.
2589 * Fixed various commands in server to check also the global list
2590 for the channel entry and not just the local list. The affected
2591 file silcd/command.c.
2593 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added assert()s to buffer formatting and unformatting routines
2596 to assert (if --enable-debug) when error occurs. Affected
2597 file: lib/silcutil/silcbuffmt.c.
2599 * Changed to auto-reconnect to check whether the remote host is
2600 router and register the re-connect timeout if it is. It used
2601 to check that whether we are normal server, but router must do
2602 auto-reconnect with another router as well. Affected file
2605 * Removed the [<key len>] option from CMODE command as the cipher
2606 name decides the key length, nowadays. See the defined ciphers
2607 from the protocol specification.
2609 * Added [<hmac>] option to the CMODE command to define the HMAC
2610 for the channel. Added SILC_CMODE_HMAC channel mode.
2612 * Added [<hmac>] option for the JOIN command so that user can
2613 select which HMAC is used to compute the MACs of the channel
2616 * Added Hmac field to the Channel Message Payload. The integrity
2617 of plaintext channel messages are now protected by computing
2618 MAC of the message and attaching the MAC to the payload. The
2619 MAC is encrypted. Now, it is clear that this causes some
2620 overhead to the size of the packet but rationale for this is that
2621 now the receiver can verify whether the channel message decrypted
2622 correctly and also when private keys are set for the channel the
2623 receiver can decrypt the packet with several keys and check from
2624 the MAC which key decrypted the message correctly.
2626 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2627 lib/silccrypt/silccipher.[ch].
2629 * Added silc_hash_len to return the digest length into the
2630 lib/silcrypt/silchash.[ch].
2632 * Rewrote parts of Silc Channel Payload interface in the
2633 lib/silccore/silcchannel.[ch]. The encode function now also
2634 encrypts the packet and parse function decrypts it.
2636 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Fixed a minor formatting bug in the SKE's key material processing.
2639 It actually might have processed the keys wrong way resulting
2642 * Redefined the mandatory HMAC algorithms and added new algorithms.
2643 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2644 and hmac-md5 truncated to 96 bits. The mandatory is now
2645 hmac-sha1-96. Rest are optional (including the one that used
2646 to be mandatory). Rationale for this is that the truncated HMAC
2647 length is sufficient from security point of view and can actually
2648 make the attack against the HMAC harder. Also, the truncated
2649 HMAC causes less overhead to the packets. See the RFC2104 for
2652 * Added new [hmac] configuration section. The SKE used to use
2653 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2654 is of course wrong. The official names that must be proposed in
2655 the SKE are the ones defined in the protocol specification
2656 (hmac-sha1-96 for example). The user can configure any hmac
2657 using any hash function configured in the [hash] section. At
2658 least, the mandatory must be configured.
2660 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2662 * Added HMAC list to the SKE proposal list. It has now both
2663 hash algorithm list and HMAC list. This makes the protocol
2664 incompatible with previous versions. The SKE now seems to work
2665 the way it is supposed to work, for the first time actually.
2667 * Defined plain Hash algorithms to the protocol specification.
2670 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Implemented support for key agreement packets into the server.
2673 Added functions silc_server_key_agreement and
2674 silc_server_send_key_agreement. Other than these functions,
2675 server has nothing to do with this packet.
2677 * Added support for private message key packets into the server.
2678 Added functions silc_server_private_message_key and
2679 silc_server_send_private_message_key.
2683 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2684 called in the protocol's final callback instead in the END
2685 protocol state. This makes a little more sense and in the same
2686 time in client we can use the same protocol routines for normal
2687 key exchange and to key agreement packet handling as well.
2689 * Added to both client's and server's KE protocol context the
2690 SilcSKEKeyMaterial pointer to save the key material. We will
2691 bring the key material to the protocol's final callback by doing
2692 this. The final callback must free the key material.
2694 * Added SKE's packet_send callback into client's KE protocol
2695 context so that the caller can choose what packet sending function
2696 is used. This way we can use different packet sending when
2697 doing normal SKE when doing key agreement packet handling (in
2698 the key agreement packet handling we do not want to encrypt
2701 * Implemented the responder side of the key agreement routines
2702 in the client. The client can now bind to specified port and
2703 accept incoming key negotiation. The key material is passed
2704 to the application after the protocol is over.
2706 * Implemented the processing of incoming Key Agreement packet
2707 in the client. Added function silc_client_key_agreement to
2710 * Implemented the intiator side of the key agreement routines
2711 in the client. The client can now initiate key agreement with
2712 another remote client. The key material is passed to the
2713 application after the protocol is over.
2715 * Created client_keyagr.c to include all the key agreement
2718 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2719 SILC_TASK_CALLBACK except that it is not static.
2721 * Created client_notify.c and moved the Notify packet handling
2722 from the client.[ch] into that file.
2724 * Created client_prvmsg.c and moved all private message and
2725 private message key routines from the client.[ch] into that file.
2727 * Create client_channel.c and moved all channel message and
2728 channel private key routines from the client.[ch] into that file.
2730 * Changed silc_client_get_client_by_id_resolve to resolve with
2731 WHOIS command instead of IDENTIFY command, in the file
2732 lib/silclient/idlist.c.
2734 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Implemented the SKE's responder side to the Client library.
2738 * When FAILURE is received to the protocol do not trust it
2739 blindly. Register a timeout to wait whether the remote closes
2740 the connection as it should do it, only after that process the
2741 actual failure. This was changed to both client and server.
2743 * Added client_internal.h to include some of the structures
2744 there instead of client.h in lib/silcclient/.
2746 * Added function silc_task_unregister_by_callback to unregister
2747 timeouts by the callback function.
2749 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * Some "Incomplete WHOIS info" errors has been appearing on the
2752 log files. Took away the entry->userinfo check from WHOIS
2753 reply sending. The entry->userinfo is now " " if client did not
2754 provide one. I thought this was fixed earlier but something
2755 is wrong still. Let's see if the error still appears.
2757 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Fixed a minor bug in the login when the channel key is
2760 re-generated in the server. It used to generate the key in
2761 wrong order and thus caused problems in the channel traffic.
2763 * Fixed a minor bug in channel key distsribution after
2764 KICK command. The key was not sent to the router even though
2767 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Added silc_ske_process_key_material_data as generic routine
2770 to process any key material as the SILC protocol dictates. The
2771 function is used by the actual SKE library but can be used by
2772 applications as well. This relates to the private message keys
2773 and the channel private keys since they must be processed the
2774 same way the normal SILC session keys. The protocol dictates
2775 this. Affected files: lib/silcske/silcske.[ch].
2777 Added also silc_ske_free_key_material to free the
2778 SilcSKEKeyMaterial structure.
2780 * Defined silc_cipher_set_key function to set the key for
2781 cipher without using the object's method function. The affected
2782 files: lib/silccrypt/silccipher.[ch].
2784 * Implemented silc silc_client_add_private_message_key,
2785 silc_client_add_private_message_key_ske,
2786 silc_client_del_private_message_key,
2787 silc_client_list_private_message_keys and
2788 silc_client_free_private_message_keys functions in the
2791 Added functions silc_client_send_private_message_key to send
2792 the Private Message Key payload and silc_client_private_message_key
2793 to handle incoming Private Message Key payload.
2795 * Added Cipher field to the Private Message Key payload to set
2796 the cipher to be used. If ignored, the default cipher defined
2797 in the SILC protocol (aes-256-cbc) is used.
2799 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Removed lib/silcclient/ops.h file.
2803 Redefined parts of the SILC Client Library API. Created new
2804 file silcapi.h that deprecates the ops.h file and defines the
2805 published Client Library API. Defined also private message key
2806 API and channel private key API into the file.
2808 This is the file that the application must include from the
2809 SILC Client Library. Other files need not be included by
2810 the application anymore.
2812 * Added new key_agreement client operation callback and also
2813 defined the Key Agreement library API for the application.
2815 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2818 is used by clients to request key negotiation between another
2819 client in the SILC network. If the negotiation is started it
2820 is performed using the SKE protocol. The result of the
2821 negotiation, the secret key material, can be used for example
2822 as private message key.
2824 Implemented the Key Agreement payload into the files
2825 lib/silccore/silauth.[ch].
2827 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Redefined ciphers for the SILC protocol. Added some new ciphers
2830 and defined the key lengths for the algorithms. Changed the
2831 code accordingly. The default key length is now 256 bits.
2833 * Fixed SKE key distribution function silc_ske_process_key_material
2834 when the key length is more than 128 bits. The default key
2835 length in SILC is now 256 bits.
2837 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2838 to indicate unsupported algorithm.
2840 * Renamed rijndael.c to aes.c and all functions as well.
2842 * Fixed a long standing channel key setting bug in client library.
2843 Weird that it has never surfaced before.
2845 * Fixed bug in channel deletion. If the entire channel is removed
2846 then it must also delete the references of the channel entry
2847 from the client's channel list as the client's channel entry and
2848 the channel's client entry share same memory.
2850 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Implemented CONNECT and SHUTDOWN commands in the client.
2854 * Implemented CLOSE command to the client.
2856 * Added the function silc_idlist_find_server_by_name into the
2857 files silcd/idlist.[ch].
2859 Added the function silc_idlist_find_server_by_conn into the
2860 files silcd/idlist.[ch].
2862 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * DIE command was renamed to SHUTDOWN. Updated the both code
2867 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2868 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2870 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2873 * Added function silc_server_create_connection function to create
2874 connection to remote router. My server implementation actually
2875 does not allow router to connect to normal server (it expects
2876 that normal server always initiates the connection to the router)
2877 so the CONNECT command is only good for connecting to another
2880 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2882 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2883 or some other client was kicked from the channel.
2885 Implemented the handling of the notify type to both client
2888 Implemented silc_server_send_notify_kicked to send the KICKED
2889 notify. It is used to send it to the server's primary router.
2891 * Implemented the KICK command into server and client.
2893 * Added `query' argument to the silc_idlist_get_client function
2894 to indicate whether to query the client from server or not if
2897 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2898 to indicate that the client is not channel founder.
2902 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Removed the rng context from SilcPacketContext structure and
2905 changed that the packet routine uses the Global RNG API.
2907 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Added support for quit message that client can "leave" on the
2910 channel when it quits the SILC. It is ditributed inside the
2911 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2913 Added silc_server_free_client_data that will take the
2914 signoff message as argument.
2916 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2918 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Updated parts of the protocol specification to keep it up
2923 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2926 payloads in one packet.
2928 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2929 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2930 use now the new List flag.
2932 * Also deprecated the following packet types: REPLACE_ID,
2933 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2935 * Added list support for Notify packet in server.
2937 * Added silc_server_send_notify_channel_change to send the
2938 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2939 the silc_server_send_replace_id.
2941 * Added silc_server_send_notify_nick_change to send the
2942 NICK_CHANGE notify type. Deprecates the function
2943 silc_server_send_replace_id.
2945 * Added silc_server_send_notify_join to send the JOIN notify type.
2946 Deprecates the function silc_server_send_new_channel_user.
2948 * Added silc_server_send_notify_leave to send LEAVE notify type.
2949 Deprecates the function silc_server_send_remove_channel_user.
2951 * Added silc_server_send_notify_cmode and
2952 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2953 types. Deprecates the silc_server_send_set_mode function.
2955 * Added SERVER_SIGNOFF notify type to indicate that server has
2956 quit. This means that all clients on the channel from that
2957 server will drop. This can be also used when netsplit happens.
2959 Deprecated REMOVE_ID packet type since it is not needed anymore
2962 Added silc_server_send_notify_server_signoff to send the
2963 SERVER_SIGNOFF notify type. Deprecates the function
2964 silc_server_send_remove_id.
2966 Added also silc_server_send_notify_signoff to send the
2967 SIGNOFF notify type.
2969 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2970 SILC protocol from this day on. Changed the protocol
2971 specification as well.
2973 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2974 notify type. It is used between routers to notify about
2975 topic changes on a channel.
2977 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2980 * Partly updated the protocol specification to comply with the
2981 changes now made. It is still though a bit outdated.
2983 * The JOIN notify type now takes one extra argument <Channel ID>.
2984 The packet used to be destined to the channel but now the
2985 JOIN type may be sent as list thus it is impossible to
2986 destine it to any specific channel. By adding this argument
2987 it is again possible.
2989 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Added CREDITS file. The CHANGES and CREDITS file will appear
2992 in the distribution as well.
2994 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2997 types in the server's silcd/packet_receive.c.
2999 * Implemented CMODE and CUMODE to work in router environment.
3001 * Fixed minor encoding and decoding buglet from the
3002 lib/silccore/silcmode.c.
3004 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3007 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3009 * Changed all SilcConfigServer* and silc_config_server* to
3010 SilcServerConfig* and silc_server_config*, respectively.
3013 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Associated the ID (client or server ID) to the Authentication
3016 Payload to avoid any possibility of forging. Updated the
3017 protocol specification and the code accordingly.
3019 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * The RSA key length is now save to the RsaKey context in the
3022 key generation process in lib/silccrypt/rsa.c. The key length
3023 is now used to figure out the maximum size of the block allowed
3024 to be encrypted/signed.
3026 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3027 is equivalent to the silc_mp_mp2bin but does not allocate any
3030 * Changed silc_mp_mp2bin API to take length argument. If it is
3031 non-zero then the buffer is allocated that large. If zero, then
3032 the size is approximated using silc_mp_sizeinbase, which however
3035 * Created Global RNG API which is global RNG that application can
3036 initialize. After initializing, any routine anywhere in the
3037 code (including library) can use RNG without allocating a new
3038 RNG object. This was done to allow this sort of use of the
3039 RNG in code that has no chance to allocate RNG object. All
3040 applications currently allocate this and many routines in the
3041 library use this. Affected file lib/silccrypt/silcrng.[ch].
3043 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3044 it to use the Global RNG API.
3046 * Defined Authentication Payload into protocol specification that
3047 is used during SILC session to authenticate entities. It is
3048 used for example by client to authenticate itself to the server
3049 to obtain server operator privileges.
3051 Implemented this payload into the lib/silccore/silcauth.[ch].
3052 Implemented also routines for public key based authentication
3053 as the new protocol specification dictates.
3055 Moved definitions of different authentication methods from
3056 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3058 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3059 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3060 silc_pkcs_verify_with_hash functions into the file
3061 lib/silccrypt/silcpkcs.[ch].
3063 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * The client entry's userinfo pointer must be always valid.
3066 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3067 will fail since it requires the userinfo. Now, the userinfo
3068 is allocated as "" if actual userinfo does not exist. Actually,
3069 it must exist and it is totally Ok to drop client connections
3070 that does not announce the userinfo. However, we will make
3071 this workaround for now.
3073 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3074 to return the remote port by socket.
3076 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3078 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3079 SILC_SERVER_PENDING_EXEC and added an new macro
3080 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3081 data or when error occurs while processing the pending command.
3083 Added new argument `destructor' into silc_server_command_pending
3084 and to the SilcServerCommandPending object. This destructor is
3085 now called after calling the pending callback or if error occurs
3086 immediately. If error occurs the actual pending callback won't
3087 be called at all - only the destructor. The destructor may be
3088 NULL if destructor is not needed.
3090 All this applies for client library code as well. Similar
3091 changes were made there as well for the pending commands.
3093 In the client, the application must now allocate the
3094 SilcClientCommandContext with the silc_client_command_alloc
3097 * Added reference counter to the SilcServerCommandContext. Added
3098 function silc_server_command_alloc and silc_server_command_dup
3101 Same type of functions added to the client library for the same
3104 * Removed the cmd_ident from IDListData away since it is now
3105 global for all connections. It is the command identifier used
3106 in command sending and with pending commands. The affected file
3109 * Added reference counter to the SilcSocketConnection objecet to
3110 indicate the usage count of the object. The object won't be
3111 freed untill the reference counter hits zero. Currently only
3112 server uses this, and client ignores it. The client must be
3113 set to use this too later. The affected files are
3114 lib/silccore/silcsockconn.[ch]. Added also the function
3115 silc_socket_dup to increase the reference counter.
3117 This was mainly added because it is possible that the socket
3118 is removed underneath of pending command or other async
3119 operation. Now it won't be free'd and proper DISCONNECTING
3120 flags, etc. can be set to avoid sending data to connection that
3121 is not valid anymore.
3123 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3124 the connection. After that it sets SILC_SET_DISCONNECTED.
3125 It is, however, possible that the socket data is not still freed.
3126 The silc_server_packet_process now checks that data is not
3127 read or written to connection that is DISCONNECTED. The socket
3128 get's freed when the reference counter hits zero.
3130 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Changed the client operation API: channel_message operation's
3133 `sender' is now the client entry of the sender, not the nickname
3134 and the `channel' is the channel entry, not the channel name.
3136 In the private_message operation the `sender' is now also the
3137 client entry of the sender not the nickname.
3139 Affected file is lib/silcclient/ops.h and all applications
3140 using the client operations.
3142 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Moved the calling of ops->connect() from connect_to_server_final
3145 into receive_new_id functin since that is the point when the
3146 client is actually allowed to send traffic to network. The
3147 affected file is lib/silcclient/client.c.
3149 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3152 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3153 (if needs broadcasting) instead of broadcasting the packets one
3154 by one which would make a burst in the network traffic.
3156 * Added `broadcast' argument to the functions in silcd/server.[ch]
3157 silc_server_create_new_channel[_with_id] to indicate whether
3158 to send New Channel packet to primary router.
3160 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Added new function into the silcd/server.[ch] files:
3163 silc_server_create_new_channel_with_id to create new channel with
3164 already existing Channel ID.
3166 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3167 lib/silccore/silcpacket.h. This packet is used t send list of
3168 Set Mode payloads inside one packet. Server uses this to set
3169 the modes for the channels and clients on those channels, that it
3170 announced to the router when it connected to it. The protocol
3171 specification has been updated accordingly.
3173 * The silc_server_new_channel did not handle the packet coming
3174 from normal server as it normally does not send that. However,
3175 when it announces its channels it does send it. Implemented
3176 the support for that.
3178 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3179 into the file lib/silccore/id.h.
3181 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3183 * Fixed memory leaks in the functions silc_idlist_del_client,
3184 silc_idlist_del_channel and silc_idlist_del_server in the file
3185 silcd/idlist.c. All of those leaked like a sieve.
3187 * Fixed some small memory leaks in the client's function
3188 silc_client_notify_by_server.
3190 * Added functions into silcd/server.c: silc_server_announce_clients,
3191 silc_server_announce_channels and silc_server_announce_server.
3192 These functions are used by normal and router server to announce
3193 to its primary router about clients, channels and servers (when
3194 router) that we own. This is done after we've connected to the
3197 These functions effectively implements the following packet types:
3198 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3199 and SILC_PACKET_NEW_ID_LIST.
3201 * Added new functions into the silcd/packet_receive.[ch]:
3202 silc_server_new_id_list, silc_server_new_channel_list and
3203 silc_server_new_channel_user_list to handle the incoming
3204 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3206 * Added support of changing Channel ID in the function
3207 silc_server_replace_id. If the server that announces a channel
3208 to the router already exists in the router (with same name but
3209 with different Channel ID), router is responsible to send
3210 Replace ID packet to the server and force the server to change
3211 the Channel ID to the one router has.
3213 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3214 client that the Channel ID has been changed by the router. The
3215 normal server sends this to the client. Client must start using
3216 the new Channel ID as the channel's ID.
3218 Implemented handling of this new type into lib/silcclient/client.c
3219 into the function silc_client_notify_by_server.
3221 * Added new function silc_idlist_replace_channel_id into the files
3222 silcd/idlist.[ch] to replace the Channel ID.
3224 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Call silc_server_command_identify_check always when processing
3227 the IDENTIFY command in silcd/command.c
3229 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3232 send keepalive packets. The packet can be sent by clients,
3233 servers and routers.
3235 Added function silc_socket_set_heartbeat into the file
3236 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3237 If not set, the heartbeat is not performed. The actual
3238 heartbeat is implemented in the low level socket connection
3239 library. However, application is responsible of actually
3242 Added silc_server_send_heartbeat to send the actual heartbeat
3243 packet into silcd/packet_send.[ch]. Server now performs
3244 keepalive with all connections.
3246 * Added silc_task_get_first function into lib/silcutil/silctask.c
3247 to return the timeout task with shortest timeout. There was a bug
3248 in task unregistration that caused problems. TODO has been
3249 updated to include that task system must be rewritten.
3251 * The client library will now resolve the client information when
3252 receiving JOIN notify from server for client that we know but
3253 have incomplete information.
3255 * Rewrote parts of silc_server_remove_from_channels and
3256 silc_server_remove_from_one_channel as they did not remove the
3257 channel in some circumstances even though they should've.
3259 * Encryption problem encountered in server:
3261 The LEAVE command used to send the Channel Key packet to the
3262 router immediately after generating it. However, the code
3263 had earlier sent Remove Channel user packet but not immediately,
3264 ie. it was put to queue. The order of packets in the router
3265 was that Channel Key packet was first and Remove Channel User
3266 packet was second, even though they were encrypted in the
3267 reverse order. For this reason, MAC check failed. Now, this
3268 is fixed by not sending the Channel Key packet immediately but
3269 putting it to queue. However, this is more fundamental problem:
3270 packets that are in queue should actually not be encrypted
3271 because packets that are sent immediately gets encrypted
3272 actually with wrong IV (and thus MAC check fails). So, packets
3273 that are in queue should be encrypted when they are sent to
3274 the wire and not when they put to the queue.
3276 However, the problem is that the current system has not been
3277 designed to work that way. Instead, the packet is encrypted
3278 as soon as possible and left to the queue. The queue is then
3279 just purged into wire. There won't be any fixes for this
3280 any time soon. So, the current semantic for packet sending
3283 o If you send packet to remote host and do not force the send
3284 (the packet will be in queue) then all subsequent packets to the
3285 same remote host must also be put to the queue. Only after the
3286 queue has been purged is it safe again to force the packet
3289 o If you send all packets immediately then it safe to send
3290 any of subsequent packets through the queue, however, after
3291 the first packet is put to queue then any subsequent packets
3292 must also be put to the queue.
3294 Follow these rules and everything works fine.
3296 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Added new function silc_server_remove_clients_by_server to
3299 remove all client entries from ID list when the server connection
3300 is lost. In this case it is also important to invalidate all
3301 client entires as they hold the invalid server entry. This
3302 fixes fatal bug when server has lost connection and will reconnect
3305 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Made some sanity checks to silc_server_daemonise like to check
3308 whether the requested user and group actually exists.
3310 * Added sanity check to SKE's silc_ske_responder_finish to check
3311 that the public and private key actually is valid.
3313 * Invalidate the client's nickname when receiving Replace ID
3314 packet and the Client ID is being replaced. This means that the
3315 server will query the nickname if someone needs it (client)
3318 * Sort the ID Cache in client library when the ID Cache data
3319 has changed (needs sorting).
3321 * Do not allow for SILC client to create several connections to
3322 several servers. The client does not support windows right now
3323 and generating multiple connections causes weird behaviour.
3325 Irssi-silc client does support windows and can handle several
3326 connections without problems, see: www.irssi.org and SILC plugin.
3328 * Fixed some places where client was added to the IDList. The
3329 rule of thumb is following (in order to get everything right):
3330 If the client is directly connected local client then the
3331 `connection' argument must be set and `router' argument must be
3332 NULL to silc_idlist_add_client function. If the client is not
3333 directly connected client then the `router' argument must
3334 bet set and the `connection' argument must be NULL to the
3335 silc_idlist_add_client function.
3337 * The funtion silc_server_packet_send_local_channel actually did
3338 not check whether the client was locally connected or not. It
3339 does that now. Fixed a bug related to LEAVE command.
3341 * Fixed Remove Channel User payload parsing bug in server's
3342 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3344 * The server's silc_server_save_channel_key now checks also the
3345 global ID list for the channel as it might not be in the local
3346 list. Fixed a bug related to LEAVE command.
3348 * Is this the end of the [<unknown>] buglet that has been lurking
3349 around for a long time? A little for loop fix in server's
3350 silc_server_command_whois_parse that is used by both IDENTIFY
3351 and WHOIS command. At least, this was a clear bug and a cause
3352 of one type of [<unknown>] buglet.
3354 * WHOIS and IDENTIFY commands call the function
3355 silc_server_command_[whois/identify]_check function even if
3356 we are not router server.
3358 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Added --with-gmp configuration option. If set the GMP
3361 is always compiled in the SILC source tree. If not set then
3362 it is checked whether the system has the GMP3 installed. If
3363 it has then the GMP won't be compiled (the system's headers
3364 and library is used), if it doesn't have it then the GMP is
3365 compiled in the SILC source tree.
3367 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Changed RSA private exponent generation to what PKCS #1
3370 suggests. We try to find the smallest possible d by doing
3371 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3372 not security fix but optimization.
3374 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Added new config entry [Identity] to fork the server and run
3377 it as specific user and group. A patch from Bostik.
3379 * Imported Dotconf configuration library into lib/dotconf.
3380 This will be used to create the SILC configuration files later.
3381 It will appear in the distsribution after this commit.
3383 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * A big code auditing weekend happening. Auditing code for
3386 obvious mistakes, bugs and errors. Also, removing any code
3389 Removed files for being obsolete:
3391 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3392 inline in the file lib/silcutil/silcbuffer.h)
3394 o lib/silcutil/silcbufutil.c (the header has inline versions)
3396 Changed code to fix possible error conditions:
3398 o The buffer formatting routines now check that the destination
3399 buffer really has enough space to add the data. This applies for
3400 both buffer formatting and unformatting
3401 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3402 unformatting was changed to accomodate following rules:
3403 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3404 sent to the function while XXX_*STRING will not allocate or copy
3405 the data into the buffer. Instead it sets the pointer from the
3406 buffer into the pointer sent as argument (XXX_*STRING used to
3407 require that the pointer must be allocated already). This change
3408 makes this whole thing a bit more consistent and more optimized
3409 (note that the data returned in the unformatting with XXX_*STRING
3410 must not be freed now). The routines return now -1 on error.
3412 o Tried to find all code that use buffer_format and buffer_unformat
3413 and added return value checking to prevent formatting and
3414 especially unformatting errors and possible subsequent fatal
3417 o Changed ske->x and ske->KEY to mallocated pointers in
3418 lib/silcske/silcske.h. Fixed possible data and memory leak.
3420 o Added return value checking to all *_parse* functions. Fixed
3421 many memory leaks as well.
3423 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3424 so that buffer overflows would not happen. All code now also
3425 checks the return value as it can fail.
3427 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Added reconnection support to server if the normal server looses
3430 its connection to the router (for example if router is rebooted).
3431 The server performs normal reconnection strategy implemented
3432 to the server. Affected file silcd/server.c.
3434 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added new packet type SILC_PACKET_SET_MODE that is used to
3437 distribute the information about changed modes (for clients,
3438 channels and clients channel modes) to all routers in the
3439 network. Updated the protocol specification accordingly.
3441 Added functions into silcd/packet_send.c and
3442 silcd/packet_receive.c: silc_server_send_set_mode,
3443 silc_server_set_mode.
3445 Added new files silcmode.[ch] into lib/silccore that implements
3446 the encoding and decoding of Set Mode Payload. Added new type
3447 SilcSetModePayload. Moved the definitions of different modes
3448 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3450 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Oops, a little mistake in server's connection authentication
3453 protocol. The protocol is not ended with FAILURE but with
3454 SUCCESS if the authentication is Ok. :) Affected file is
3457 * Implemented NICK_CHANGE notify handling in server in the file
3458 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3459 the local clients on the channel. After the changing nickname
3460 in router environment snhould work and the [<unknown>] nickname
3461 should appear no more.
3463 The silc_server_replace_id function that receives the Replace ID
3464 payload now sends the NICK_CHANGE notify type also in the file
3465 silcd/packet_receive.c
3467 * Changed WHOIS and IDENTIFY command to support the maximum amount
3468 of arguments defined in protocol specs (3328 arguments). This
3469 fixed a bug that caused problems when there were more than three
3472 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Added extra parameter, command identifier, to the
3475 silc_client_send_command so that explicit command identifier
3478 Changed that ID list routines uses specific command identifier
3479 when sending WHOIS/IDENTIFY requests to the server so that they
3480 can be identified when the reply comes back.
3482 Affected files lib/silcclient/command.[ch],
3483 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3485 * Added `sender' argument to silc_server_packet_send_to_channel
3486 to indicaet the sender who originally sent the packet to us
3487 that we are now re-sending. Ignored if NULL. Affected file
3488 silcd/packet_send.[ch].
3490 * Added some server statistics support in silcd/server_internal.h
3491 SilcServerStatistics structure and around the server code. Also
3492 send some nice statistics information when client is connecting
3495 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Fixed channel ID decoding in server's JOIN command reply in
3498 silcd/command_reply.c
3500 * Fixed braodcasting of replace ID payload to not to send it if
3501 we are standalone server in silcd/packet_receive.c.
3503 * Fixed all channel message sending routines to not to send
3504 packets to clients that has router set, since they are routed
3505 separately in the same function earlier. Affects file
3506 silcd/packet_send.c and all channel packet sending functions.
3508 * In USERS reply, res_argv[i] are not allocated, the table
3509 is allocated. Thus changed that free the table, not its
3512 * In server's whois_check and identify_check if the client is
3513 locally connected do not send any WHOIS commands - they are not
3516 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Fixed some minor bugs in client when sending WHOIS command. The
3519 arguments was in wrong order.
3521 * Removed statis function add_to_channel from server in
3522 silcd/command.c that was previously used with the joining but
3525 * Tested USERS command in router environment successfully with two
3526 routers, two servers and two clients.
3528 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Reorganized the USERS command and command reply in client library
3531 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3532 When the command is given by user we register a pending command
3533 callback that will reprocess the command after the reply has been
3534 received from the server. When reprocessing the packet we then
3535 display the information. Thus, the USERS information is displayed
3536 now in the command callback instead of in the command reply
3537 callback. The processing of the command is same as previously
3538 when server has sent the command reply in the JOINing process.
3540 * Added to USERS command in silcd/command_reply.c to join the client,
3541 we didn't use to know about, to the channel after we've created
3542 a client entry for it. Also, for clienet we did know already still
3543 check whether it is on the channel or not and add it if not.
3545 * Removed silc_server_command_join_notify as the function and its
3548 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Changed the client's pending command handling to the same as the
3551 server's pending command handling. It is also now possible to
3552 execute command reply functions from other command reply
3553 function as the function callbacks for commands and command
3554 replies are one and same. The pending commands are not static
3555 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3556 in client connection context. Thus, pending commands are server
3557 connection specific as it is convenient.
3559 Changed the function silc_client_command_pending and
3560 silc_client_command_pending_del and added new function
3561 silc_client_command_pending_check. Removed the
3562 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3565 * Added cmd_ident, current command identifier, to the client
3566 connection context in lib/silcclient/client.h to keep track on
3567 command identifiers used in command sending. Client's command reply
3568 function handling now supports the mandatory command identifiers.
3570 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3571 funtions in client to fully support pending command callbacks.
3573 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3574 as one of the arguments to the application in the command reply
3577 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3578 before first releasing SILC but came back. Now it is removed again
3579 and should come back nomore. The FORWARDED flag was used only
3580 by the JOINing procedure by forwarding the command packet to router.
3581 Now, the JOINing procedure has been changed to more generic (due
3582 to various router environment issues) and FORWARDED is not needed
3583 anymore for anything. The protocol specification is yet to be
3586 Now, removed silc_server_packet_forward from server and the flag
3587 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3589 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Renamed NAMES command to USERS command. The NAMES was named that
3592 due to historical reasons. Now it is renamed. Also, rewrote
3593 parts of the USERS command. The nickname list is not sent anymore
3594 by the server. Only Client ID and mode lists are sent in the USERS
3595 command. Changed this also to the protocol specification.
3597 The client now resolves the names and stuff after it receives
3598 the USERS list from the server when joining to the channel.
3600 * WHOIS and IDENTIFY commands has been changed to support multiple
3601 Client ID's per command. One can now search for multiple users
3602 in the network by sending only one WHOIS or IDENTIFY command.
3603 Changed the code and the protocol specifications.
3605 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3606 uses silc_server_command_whois_parse to parse the request. */
3608 * If normal server, do not parse the WHOIS and IDENTIFY requests
3609 before sending it to the router. Saves some time.
3611 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Fixed JOIN command on client library. Wrong number of arguments
3614 used to crash the client.
3616 * Added silc_server_channel_has_global function to check whether
3617 channel has global users or not.
3619 * Added silc_server_channel_has_local function to check whether channel
3620 has locally connected clients on the channel.
3622 * The silc_server_remove_from_one_channel now checks whether the
3623 channel has global users or not after given client was removed from
3624 the channel. It also checks whether the channel has local clients
3625 on the channel anymore. If it does not have then the channel entry
3626 is removed as it is not needed anymore.
3628 * The silc_server_notify now checks on JOIN notify whether the joining
3629 client is one of locally connected or global. If it is global then
3630 the channel has now global users on the channel and that is marked
3631 to the channel entry. Also, it now saves the global client to
3632 global list who is joining and JOINs it to the channel. This is
3633 for normal server, that is.
3635 Changed silc_server_send_notify_on_channel,
3636 silc_server_packet_relay_to_channel and
3637 silc_server_packet_send_to_channel check if we are normal server
3638 and client has router set (ie. global client) do not send the
3639 message to that client, as it is already routed to our router.
3641 * Implemented LEAVE notify type handling in silc_server_notify
3644 * Tested LEAVE command in router environment successfully. Tested
3645 with two routers, two servers and two clients.
3649 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3651 * Implemented SIGNOFF notify type handling in silc_server_notify
3654 * silc_server_remove_id now removes the client entry from all channels
3655 it has joined and thusly sends SIGNOFF notify type.
3657 * Rewrote the NAMES list generation in server by removing two excess
3658 loops. The lists are created now inside one loop.
3660 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * silc_server_remove_channel_user checks now also global list
3663 for channel and client.
3665 * silc_server_new_channel_user checks now both local and global
3666 list for channel and client. Fixed a bug in client id decoding.
3667 Used to decode wrong buffer.
3669 * silc_server_channel_message checks now both local and global
3670 list for channel entry.
3672 * Tested channel joining (hence JOIN) in router environment
3673 successfully. Tested with two routers, two servers and two
3676 * Tested channel message sending in router environment successfully.
3678 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added silc_server_save_channel_key into server.[ch] to save the
3681 received channel key in Channel Key payload processing. It is
3682 also used in JOIN command reply handling.
3684 Equivalent function silc_client_save_channel_key added into
3685 client.[ch] into client library.
3687 * Changed JOIN command reply to send information whether the channel
3688 was created or not (is existing already) and the channel key
3689 payload. Changed protocol specs accordingly.
3691 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3692 the request was sent by ID and not by nickname. Crashed on
3695 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3698 now correctly save the received data.
3700 * silc_server_free_sock_user_data now notifies routers in the
3701 network about entities leaving the network.
3703 At the same time implemented functions silc_server_remove_id
3704 and silc_server_send_remove_id to receive and send REMOVE_ID
3705 packets. The packet is used to notify routers in the network
3706 about leaving entities. The ID removed will become invalid in
3709 * Added function silc_idlist_del_server into server. Removes and
3710 free's server entry from ID list.
3712 * silc_server_private_message function now checks, if we are router,
3713 that the destination ID really is valid ID, naturally.
3715 * In router when NEW_ID packet is received (for new client) the
3716 hash of the Client ID is saved in the ID Cache but the
3717 client->nickname is set to NULL, instead of putting the hash
3720 IDENTIFY command now also checks that client->nickname must be
3721 valid. If it is not if will request the data from the server who
3722 owns the client. Added new function
3723 silc_server_command_identify_check.
3725 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3726 to set the command to already allocated Command Payload.
3728 * Tested private message sending in router environment with two
3729 routers, two servers and two clients. Fixed minor bugs and now
3732 * Fixed segfault from client's NAMES command. Used to crash if
3735 * Forwarded packets must not be routed even if it is not destined
3736 to the receiver. Changed server code comply with this.
3738 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added `require_reverse_mapping' boolean value to ServerParams
3741 structure. If TRUE (not default) the server will require that
3742 the connecting host has fully qualified domain name.
3744 If the reverse mapping is not required and hostname could not be
3745 found the IP address is used as hostname.
3747 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Implemented version string checking to both client and server.
3750 The check is incomplete currently due to the abnormal version
3751 strings used in development version of SILC.
3753 * Changed all command functions in server to use the new
3756 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Changed char *data to unsigned char *data in ID Cache system to
3759 support binary data as ID Cache data. Changed code to support
3760 binary data in lib/silccore/idcache.c.
3762 * Renamed silc_server_packet_relay_command_reply to
3763 silc_server_command_reply as it is normal packet receiving
3764 function. Rewrote the function to accept command replys for
3765 servers and not only for clients.
3767 * Mark remote router always as registered server if we are connecting
3768 to it. Otherwise, commands sent by the router to us are ignored.
3770 * All ID List find routines now returns the ID Cache Entry pointer
3771 as well if requested.
3773 * WHOIS command works now in router environment, tested with two
3774 routers, two servers and two clients.
3776 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3777 in router environment (as it is almost equivalent to WHOIS) but
3778 hasn't been tested thoroughly. Added new functions:
3780 silc_server_command_identify_parse
3781 silc_server_command_identify_send_reply
3782 silc_server_command_identify_from_client
3783 silc_server_command_identify_from_server
3785 * Disabled route cache adding because adding two different ID's with
3786 same IP replaces the old cache entry thus giving wrong route.
3787 The entry->router->connection is always the fastest route anyway
3788 so route cache may not be needed. Of course, new routes maybe
3789 established after receiving the ID when the entry->router->connection
3790 might not be anymore the most optimal.
3792 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Add route cache for received ID for fast routing.
3796 * Added silc_server_packet_route to route received packet on router
3797 that is not destined to us.
3799 * Renamed silc_server_get_route to silc_server_route_get.
3801 * Added id_string and id_string_len fields into SilcServer to
3802 include encoded ServerID for fast comparing without excess
3803 encoding of the ID's.
3805 * Cleaned up WHOIS command on server side. Added following static
3808 silc_server_command_whois_parse
3809 silc_server_command_whois_check
3810 silc_server_command_whois_send_reply
3811 silc_server_command_whois_from_client
3812 silc_server_command_whois_from_server
3814 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3815 arguments in command replies. All command functions should be
3816 updated to use this macro.
3818 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Minor typo fixes on command reply handling on server.
3822 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Added silc_server_command_add_to_channel internal routine to add
3825 the client to the channel after router has created the channel and
3826 sent command reply to the server.
3828 * Added generic silc_server_send_command to send any command from
3831 * Use static buffer with ID rendering instead of duplicating data.
3833 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * Fixed a channel user mode bug when joining to a channel server gave
3836 everybody channel founder rights, oops.
3838 * We mark ourselves as the router of the incoming server connection
3839 if we are router ourselves. This way we can check in some packet
3840 sending functions whether it is locally connected server. For
3841 incoming router connections we put NULL.
3843 * For router sending packets locally means now always sending the
3844 packet cell wide; to local clients and local servers. For normal
3845 server sending packet locally means sending it to only local
3848 * Fixed the JOIN command to really work in router environment. If the
3849 channel is created it is always created by the router. Router is
3850 also responsible of making the initial joining to the channel,
3851 sending JOIN notify to the sending server and distributing
3852 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3853 does not exist server doesn't do anything else but forward the
3854 command to the router which performs everything.
3856 * Added silc_server_send_channel_key function to send the Channel Key
3859 * Added silc_server_create_channel_key to create new channel key. The
3860 channel key is now re-generated everytime someone joins or leaves
3861 a channel, as protocol dictates. Note: channel->key_len is the
3864 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3867 packet_receive.[ch] to separate packet sending and receiving
3868 routines. The server.[ch] now includes everything else including
3869 actual packet processing (writing and reading data) and other
3872 Renamed silc_server_private_message_send_internal to
3873 silc_server_send_private_message. The routine is still though
3874 used only to relay private messages as server does not send
3875 private messages itself.
3877 Renamed silc_server_new_channel to silc_server_create_new_channel
3878 and added new function sicl_server_new_channel that handles the
3879 incoming New Channel packet. Added also new sending function
3880 silc_server_send_new_channel to send New Channel Payload.
3882 * Added new function silc_server_notify to process incoming notify
3883 packet to the server/router. Server may then relay the notify
3884 to clients if needed.
3886 * Added new function silc_server_new_channel_user to process incoming
3887 New Channel User packet. Router will redistribute the packet and
3888 send JOIN notify to its local clients and locally connected servers
3889 if needed. Normal server will send JOIN notify to its local client
3890 on same channel when received this packet. Added also corresponding
3891 sending function silc_server_send_new_channel_user to sent the
3894 * Added boolean route argument to send_notif_to_channel and
3895 packet_send_to_channel functions to attempt to route the packet
3896 if it is TRUE and send only locally if it is FALSE.
3898 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * silc_server_replace_id now broadcasts the received replace ID
3901 packet if it is not broadcast packet already. The router must
3902 broadcast to inform other routers about changed ID.
3904 * Added backpointer to server's router into SilcServer context in
3905 silcd/server_internal.h.
3907 * Fixed silc_server_packet_broadcast to send correct broadcast
3910 * The channel key is now distributed to the local client as soon
3911 as it is received from the router (in router environment) so that
3912 no other packet may be sent for the channel until client has
3915 * silc_server_remove_channel_user now broadcasts the received
3916 Remove Channel User packet if it is not broadcast packet already.
3917 The router must broadcast to inform other routers about removed
3920 * Added users field into SilcPacketContext that is a reference count
3921 of the context. One can increase the reference count by calling
3922 silc_packet_context_dup which is now changed to just increase the
3923 reference count instead of duplicating the data. The reference
3924 count is decresed by calling silc_packet_context_free that will
3925 free the data after the reference count hits zero.
3927 For now on the packet context and everything allocated into it
3928 (including the raw packet from network) must be freed by calling
3929 the new silc_packet_context_free function. Added also new function
3930 silc_packet_context_alloc that must be used now to allocate the
3931 context. This also means that if a routine is asynchronous from
3932 silc_[client/server]_packet_parse_type the packet context must
3933 be duplicated by calling silc_packet_context_dup. Otherwise it
3934 gets free'd after silc_[client/server]_packet_parse_type returns.
3935 Also, one must remember that if packet is duplicated then its
3936 reference count must be decresed by calling the free function as
3937 many times as it was duplicated.
3939 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3940 from both client and server.
3942 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Made joining to a channel working in router environment.
3946 * Cleaned up JOIN command on server side and create function
3947 silc_server_command_join_channel internal routine to make the
3950 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Changed silc_command_pending list to SilcDList. Also, added
3953 `ident' field to SilcServerCommandPending structure to identify
3954 the reply and to call correct callback.
3956 Added silc_server_command_pending_check function to replace the
3957 corresnponding macro. The silc_command_pending list is not
3960 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3961 to set identifier to previously allocated Command Payload. It
3962 is used to set identifier for command when resending Command
3965 * Added silc_command_payload_encode_payload to encode Command
3966 Payload buffer from SilcCommandPayload structure.
3968 * Added silc_argument_payload_encode_payload to encode Argument
3969 payload buffer from SilcArgumentPayload structure.
3971 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Changed WHOIS command to support router connection on server side.
3974 The whois request is always sent to router unless the server is
3975 standalone server. After server has received the reply from the
3976 router will it send the reply to the client.
3978 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3979 broadcast received broadcast packet. The function is used only
3980 by router. The broadcast packet is always sent to the router's
3983 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3984 render given ID to printable string, for log files for example.
3986 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Made basic router to router connections working. At least they
3989 can now connect to each other but nothing really works the way
3990 they are supposed - yet.
3992 * Added new initiator token to RouterConnection configuration
3993 file in silcd/serverconfig.[ch]. It is used to tell whether we
3994 are the initiator to the remote router or whether we'll expect
3995 the other end to connect.
3997 * Moved registering of listener task to silc_server_init, hence
3998 the server starts listenning as soon as it is run, even if it
3999 does not have connections to other routers. Let's see how well
4002 * Changed default connection retry timeouts for more suitable in
4005 * Removed cipher and such arguments from silc_idlist_add_client
4006 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4007 Added new function silc_idlist_add_data to add the keys and stuff
4010 * Added SilcIDListData structure and added it to SilcClientEntry
4011 and SilcServerEntry as their first field in the structure. This
4012 way we can explicitly cast the ID entries to the SilcIDListData
4013 structure and get common data for the entries. In past, we had
4014 to first check what type of connection it is and then cast it to
4015 correct ID entry type. Now, we can directly cast the opaque
4016 pointer to the SilcIDListData (no matter what ID entry it actually
4017 is) and get the data needed.
4019 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4022 in some circumstances even if threre were timeout tasks, though not
4023 IO tasks, but tasks anyway. Now fixed.
4025 * Defined SilcServerConnection structure to hold connection specific
4026 stuff about directly connected servers and routers. The definition
4027 is currently in silcd/server_internal.h. I thought about having
4028 a bit more important role fro this struct but for now it is used
4029 only when connecting to other server (or router actually).
4031 * Added connecting retry support in server when connecting to
4032 router(s). The retry feature implement exponential backoff
4033 algorithm. Also, added SilcServerParams structure to hold default
4034 parameters for server. For now, it include these retry settings
4035 and are hard coded. After server is moded to be as Silc Server
4036 Library this structure will be more important.
4038 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Changed client librarys channel->clients table to SilcList and
4041 changed code accordingly.
4043 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Changed client's channel table to SilcList and changed code
4046 accordingly. Also changed SilcChannelClientEntry to include back-
4047 pointer to the channel so that client entry can use that structure
4048 as list as well and we have fast cross-reference to the channel.
4049 This change dramatically decreased the complexity of channel
4050 handling with client entry and vice versa (removed one extra
4051 loop when searching for channel entry from many functions).
4053 * Changed server->sim from table to SilcDList and changed code
4056 * NAMES command can now be used from user interface. It will show
4057 the user list on the channel, neatly.
4059 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4060 Code now saves realname of the user if it becomes available.
4062 * Renamed configure.in to configure.in.pre and made ./prepare
4063 script to automatically add correct version string to
4064 configure.in which it creates from configure.in.pre.
4066 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * NAMES command reply now shows users mode with the nickname when
4071 * Moved silc_client_ch[u]mode[_char] functions from
4072 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4073 place sucks, they are utility functions and should be in some
4076 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4078 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4081 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Added TRQ (efficient deque and list library) into lib/trq. This is
4086 a very good list library that is currently used in the SILC. Defined
4087 SilcList API over the library because I didn't like the API very
4088 much. See lib/trq/silclist.h for the API and examples of how to
4089 use the API. Fixed various places in the code to use the new
4090 SilcList API. The SilcList is meant for lists that has a structure
4091 already defined as a list. It is not suitable to add just some
4092 context to the list (in TRQ, the context is the list actually).
4094 So, I defined SilcDList that can be used for the purpose where
4095 predefined list structure does not exit. This can be used as
4096 such list. Now some context just can be added to the SilcDList.
4097 Currently this list is not used in the SILC just yet, though there
4098 are a lot places where this can replace dynamically allocated
4099 tables and I will fix these places, later, to use SilcDList.
4100 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4101 and use TRQ internally).
4103 Also fixed some annoying warning messages that the original TRQ
4104 code generated. Also minor changes to TRQ's Makefile.in.
4106 * Added support for querying by Client ID to both WHOIS and
4107 IDENTIFY commands into server, as required by the protocol.
4109 * Removed method function pointers from SilcBuffer structure. They
4110 weren't used to anything and just increased the context size for
4111 no good reason. This change also made silc_buffer_alloc and
4112 silc_buffer_free functions inline functions.
4114 * Disabled command flooding detection support until it's fixed so
4115 that it accepts commands in but does not execute them more than once
4118 * Added silc_net_localhost(), to return local hostname, into
4119 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4120 that must be initialized before calling silc_client_init.
4122 * Added new function: silc_server_send_notify_on_channels to send
4123 notify messages to all channels client has joined. It is assured
4124 that the message is sent only once per client.
4126 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4127 lib/silcutil/silcutil.[ch] as silc_format function. The new
4128 function is generic and is used by server as well, not only by
4129 the logging routines.
4131 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4132 the provided version string was not acceptable. Added new function:
4133 silc_ske_check_version into lib/silcske/silcske.h. The function
4134 must be implemented by the application (client or server) and it
4135 does not reside in the SKE library. The function checks the version
4136 string remote end sent.
4138 * Added back pointers (to opaque context and to SilcSocketConnection)
4139 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4141 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4142 duplicate packet context structure.
4144 * Changed `notify' client operation to send same arguments as client
4145 receives from server except for ID's. ID's are mapped to correct
4146 ID entry and that is returned. Also, if channel entry is not sent
4147 by server but the notify is for channel the channel entry is sent
4148 to application (otherwise application doesn't know that it is for
4149 channel (library gets it from packet's Destination ID)).
4151 * Added silc_client_remove_from_channels into client library to
4152 remove a client from all channels it has joined to. Used when
4153 received SIGNOFF notify from server. Added also new function
4154 silc_client_replace_from_channels to replace old ID entry with
4155 new ID entry on all channels. Used when received NICK_CHANGE
4158 * Fixed ID Cache list handling in silc_idlist_get_client in
4159 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4160 to get (or query) client by ID.
4162 * Updated TODO list.
4164 * Added connection authentication status message defined by the
4165 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4166 support for these into the code in client and server side.
4168 * Added generic function silc_client_send_command to send any command
4169 with variable argument list. Application should use this function
4170 to send commands if the command functions provided by the library
4171 does not suite for the application's user interface needs.
4173 * Added new `failure' client operation. Application is notified about
4174 received failure packet if client is executing a protocol. In this
4175 case the protocol's execution has failed.
4177 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4178 is required by the protocol.
4180 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4181 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4184 * Added status flag to SilcSKE object to indicate realtime status
4185 of the SKE protocol.
4187 * Application receives now exactly same command reply arguments as
4188 the library receives from server. However, if ID is received the
4189 corresponding ID entry is returned to the application (eg. Client
4190 ID is mapped to correct SilcClientEntry entry and that is returned).
4191 Changed command_reply client operation due to this change.
4193 * Changed all ID's in commands and in command replys as ID Payloads.
4194 Change affected both client and server side codes.
4196 All ID's sent in SILC network (with execption of ID's in SILC
4197 Packet header) are sent in ID Payload to support variable length
4200 * Server now notifies nick changes and notifies all clients on
4201 the channels about the new nickname (about the new Client ID,
4204 * Implemented CMODE command to change channel modes. Supports all
4205 channel modes defined by the protocol specs except ban and invite
4206 lists. (Also, private channel key mode is supported but support for
4207 setting private channel key in client is missing, thus, this mode
4208 has no effect on client side (except that server requires that the
4209 client uses private channel key and normal channel traffic does not
4212 Also, invite mode works per se, but INVITE command does not work
4213 yet correctly, so you can set channel as invite only channel but
4214 inviting clients to the channel does not work (it is yet to be
4215 thought what's the best way to do it).
4217 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4218 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4219 Implemented CUMODE command to change user's mode on the channel.
4220 Supports all modes defined by the protocol specs.
4222 * Added NAMES command reply to return users modes on the channel.
4224 * Removed unnecessary and slow ciphers from lib/silccrypt.
4226 * Set SO_KEEPALIVE option to connection sockets by default.
4228 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4230 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4231 redefined the Notify Payload into protocol specs.
4233 * Added silc_id_payload_parse_id to get ID directly from raw
4236 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4239 accept searching by Client ID as well.
4241 * Added support for LEAVE and SIGNOFF notify types in client library.
4243 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4244 to parse ID Payload from raw data.
4246 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Added flags parameter into silc_ske_assemble_security_properties
4249 function in lib/silcske/silcske.[ch].
4251 * Changed notify client operation to fit better for notify messages
4252 sent by server. The notify payload received from server is now
4253 passed to the application (after parsing it to SilcNotifyPayload).
4254 It is application's responsibility to retrieve the arguments
4255 from the payload and show the message the way it wants. The message
4256 sent by server is implementation specific.
4258 * Changed public keys to comply with the protocol specification.
4259 Old public keys are not supported anymore and are not compatible.
4261 * Removed nickname from Channel Payload as the latest draft removed
4262 it. The client must resolve the nickname from the NAMES command
4263 reply received when it joined the channel.
4265 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4267 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Fixed some errors in protocol specification drafts.
4271 * Created lib/silccore/silcnotify.c to implement Notify Payload
4272 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4273 generic payloads described by protocol specifications. The file
4274 includes implementations for ID Payload and Argument Payload.
4276 * Changed Command Payload implementation to use the new Argument
4277 Payload. Changed command_xxxx_payload to command_payload_xxxx
4278 to comply with SILC coding conventions.
4280 * Added suppport for Argument Payload handling in Notify Payload
4281 implementation as protocol requires it. Added the new support
4282 into server and client lib as well.
4284 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Added support for multiple nicknames on same channel. [n] is
4287 added locally to the nickname if there are more than one same
4288 nicknames on the channel.
4290 * Server now sends all nicknames that matched WHOIS request.
4291 Client also shows the list received from server.
4293 * Added TOPIC command to client side. User can now set and show
4294 current topic on channel.
4296 * Added MOTD command to client and server. Also, server sends the
4297 motd when client connects to the server.
4299 * Changed version strings to comply ISO 8601.
4301 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Fixed protocol error handling in client library. It should now
4304 cope even if the SKE fails for some reason.
4306 * Made new protocol specification drafts for submitting to IETF.
4308 * Implemented TOPIC command to server in silcd/command.c.
4310 * Added two new notify types into lib/silccore/silcnotify.h:
4311 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4312 notify nickname change and topic setting/change on a channel.
4314 * API change of command_reply operation in client library. The
4315 application gets now the status type received from server as well.
4317 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4321 * Cras fixed and optimized the packet handling even further and
4322 it should work now. Minor change to the prototype of function
4323 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4325 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Added new function into lib/silcutil/silcschedule.[ch]:
4328 silc_schedule_with_fd to select() a specified fd. The function
4329 returns after timeout expires or data arrives or goes. The
4330 function is used by packet routines to wait that all data is
4331 received from network.
4333 * Fixed data reading from network in lib/silccore/silcpacket.c.
4334 The code now assures that all data is read from the fd and then
4335 continues packet processing. This was a bug fix since the code
4336 used to drop some data in some circumstances.
4338 * Added new function into lib/silcclient/client.[ch]:
4339 silc_client_start_key_exchange to start key exchange after
4340 connection has been established to server. The code internally
4341 now uses this funtion but its main purpose was to provide it
4342 for applications that perform their own connecting. After
4343 application has created a connection it merely calls this
4344 function to start the key exchange between client and server.
4345 The library takes care of everything else after that.
4347 Updated also lib/silcclient/README to explain the usage of
4350 * Do not send to application information that connection has
4351 been established. Application gets notified it by connect
4354 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Applied cras's patch to add silc_schedule_one function. The
4357 function runs scheduler once and returns.
4359 * Fixed the scheduler after cras messed it up. The timeout
4360 handling works now as it's supposed to work.
4362 * Added into lib/silccore/ silcnotify.h to include notify
4363 message types support. Changed silc_server_send_notify*
4364 functions, in server.[ch], to support those new notify types.
4365 Added the support for the notify types into client library,
4366 as well. Added new notify client operation into ops.h in
4369 * Changed silc_server_packet_send_to_channel to send normal
4370 packets instead of just channel message packets. The function
4371 is now used to send the notify packets to channels. It is not
4372 used to send channel message packets anymore, as server never
4375 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4376 va_arg()s as it seems to require it nowadays. I guess, if SILC
4377 is compiled with older va_arg() the new code should work anyway.
4379 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Splitted core library. Core library (lib/silccore) includes
4382 now only SILC protocol specific core (and common) components.
4383 Created new utility library (lib/silcutil) that includes more
4384 generic purpose stuff. The stuff for util library was taken
4385 from the old core library. This was minor and easy split.
4387 * Created SILC Client Library (lib/silcclient) that includes
4388 implementation of the SILC client without user interface. This
4389 was major move from silc/ directory. The code has been changed
4390 so that it is transparent towards the user interface. The
4391 silc/ directory includes now the same user interface as before
4392 and it uses the new client library. Read lib/silcclient/README.
4393 Basicly, the client library performs everything else related
4394 to SILC except user interface handling. Also, configuration
4395 files are considered to be part of user interface and library
4396 does not handle them.
4398 This change also changed a lot of structures, function naming etc.
4399 Most important change was that SilcClientWindow object was
4400 renamed to SilcClientConnection in the client library. Created
4401 also new file lib/silcclient/ops.h. Also added new files
4402 silc/local_command.[ch] and silc/client_ops.[ch].
4404 All these changes were made to make it easier for user interface
4405 designers to create what ever user interface for the SILC client
4408 It is also expected that the server will be moved to lib
4409 directory as well and SILC Server Library will be created;
4410 sometimes in the future.
4412 * Removed Local commands from lib/silccore/silccommand.h as
4413 they are application specific and new client library does not
4414 handle any of those anymore.
4416 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4417 old client implementation in silc/.
4419 * Added support for callback functions in SILC_LOG_* macros.
4420 Application can now set its own callbacks that will be called
4421 instead of using the default functions that will always print
4422 the debug messages to stderr (or stdout). Also, debugging can
4423 now be disabled by setting silc_debug to FALSE and re-enabled by
4424 setting it to TRUE. Note, that logging will still work even
4425 if debugging is disabled.
4427 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4428 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4429 silc_log_reset_debug_callbacks.
4431 * To enable debugging in silc client one must give now -d
4432 option on command line.
4434 * Changed silc_schedule_init to automatically allocate task queues
4435 if they are not allocated before calling it.
4437 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Added GMP 3.1 into math library.
4441 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4444 a channel in SILC network. The packet is used by servers and
4445 routers to notify other routers that user has left a channel.
4446 This little feature was missing until now. Added the feature
4447 to protocol specification as well.
4449 Added functions: silc_server_send_remove_channel_user and
4450 silc_server_remove_channel_user into server.[ch].
4452 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4453 lib/silccore/silcpacket.h. However, they are not implemented
4456 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Fixed joining to a channel and sending channel messages
4459 between server and router. The channel message sending should
4460 now work inside a cell.
4462 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Fixed the private message sending between server and router.
4465 The private message sending should now work inside a cell.
4467 * Added silc_server_replace_id into server.[ch] to replace
4468 existing ID in the SILC network.
4470 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4471 and silc_idlist_replace_server_id into idlist.[ch] in server.
4473 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Fixed the server to server connections. Server can again now
4476 connect to router. Router to router connections probably does
4479 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Added dynamic protocol registering support. Now protocols can
4482 registered and unregistered on the fly. Patch by cras.
4484 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Added lib/contrib directory to hold routines that some platforms
4487 don't have but are needed by SILC.
4489 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4490 into lin/contrib to provide getopt() and getopt_long() for
4491 those who don't have it.
4493 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Added AWAY command to client. When away message is set and
4496 client receives a private message packet the client automatically
4497 replies to the sender with the away message.
4499 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4500 bug seemed to be the cause of recent problems when compiling
4503 * Added version detection support to SKE protocol specification
4504 and added the new changes to the SKE implementation as well.
4505 There were other minor changes in the SKE protocol as well.
4507 Many changes in lib/silcske/silcske.[ch] and in
4508 lib/silcske/payload.[ch].
4510 * Added ^U functionality, clear input line. Patch from cras.
4512 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Mainly small bugfixes on core library. Fixed some debugging
4515 logging and buffer overflow in silclog.c.
4517 * Updated config.sub and config.guess on the distribution tree.
4519 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added command lagging support in server. Client may execute
4522 commands now only once in two seconds.
4524 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Optimized packet reception. MAC computation and checking is now
4527 also more optimized. A lot previously duplicated code is now
4528 used as generic by both client and server.
4530 * Fixed key pair generation in clientutil.c
4532 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Added into lib/silccore/silcbufutil.[ch] new function;
4535 silc_buffer_realloc.
4537 * Moved generic packet sending/encryption functions to
4538 lib/silccore/silcpacket.[ch] from client and server. Some
4539 rewriting of the functions.
4541 * Moved all generic packet reception/decryption functions to
4542 lib/silccore/silcpacket.[ch] from client and server. The
4543 packet processing is now much cleaner in both client and server.
4544 These were major changes in both client and server.
4546 * Created many common functions in server to do packet sending.
4547 Previously code were duplicated a lot, this has been removed
4550 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Rewrote major parts of the ID cache system. Don't know
4553 whether it is better now or not but at least the API is more
4556 * Major rewrite on ID cache stuff on client because of the ID
4557 cache API changes. Added idlist.c to client.
4559 * Also major rewrite on ID cache stuff on server as well.
4560 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4561 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4562 in hand, instead they are all put into the ID cache system now.
4563 All server_idlist_* routines uses ID cache now instead of
4564 traversing its own lists (those lists does not exist anymore).
4565 SilcIDList though still exists. Also, SilcXXXEntry's are
4568 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Finally made the SKE implementation compliant to the protocol
4571 specification. All mp integers are now binary encoded as
4572 opposed being HEX encoded.
4574 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4577 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4578 functions: silc_[encode/decode]_pem. Also added function
4579 silc_encode_pem_file to PEM encode with newlines ('\n') for
4582 * SILC public keys are now encoded either PEM or binary. Same
4583 option is for private keys as well. By default private keys
4584 are binary encoded and public keys PEM encoded. Silly HEX
4585 encoding were removed.
4587 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4588 function to create fingerprints.
4590 * Fixed a bug in SHA1; does not change the original data anymore.
4592 * Partly implemented INFO command on client and server side.
4593 Fixed CLEAR command. Changes to SERVER command; show current
4594 server(s) when giving command without arguments. Added
4595 VERSION command to client.
4597 * Added check to server that unregistered connections cannot
4598 execute commands (unless it is specificly allowed).
4600 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Fixed screen refresh.
4604 * Fixed channel joining bug from client. On some circumstances
4605 client tried to join to a channel it had already joined.
4607 * Added public key verification process into client's protocol.c.
4608 The client now verifies the public key from user and saves
4609 it into ~./silc/serverkeys/ directory.
4611 Added into: clientutil.[ch]: silc_client_verify_server_key.
4613 * Changed SKE protocol's silc_ske_initiator_finish function
4614 to accept callback function that verifies the received public
4615 key. Removed old silc_ske_verify_public_key function.
4617 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4620 silc_pkcs_private_key[_data]_set.
4622 * Made the password and public authentication more cleaner in
4623 server's protocol.c.
4625 * Removed historic and obsolete protocol `channel_auth' from
4626 both client and server.
4628 * Removed wrong way of sending command status messages from
4629 server to client in server's command.c. The old way violated
4630 protocol specification.
4632 Changes to silccore/silccommand.[ch]: removed
4633 silc_command_encode_status_payload -> not needed anymore,
4634 changed silc_command_encode_payload_va to accept extra
4635 argument on variable argument list. The argument type must
4636 now be provided to the function. Also, added new function:
4637 silc_command_encode_reply_payload_va which is same as
4638 normal command_encode_payload_va except command status type
4639 is provided as extra argument.
4641 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added ~./silc directory handling. The directory includes the
4644 public and private keys for the client.
4646 Added silc_client_check_silc_dir, silc_client_create_identifier
4647 and silc_client_load_keys.
4649 * Implemented SILC protocol compliant public key. Added public
4650 and private key saving to and loading from files.
4652 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4653 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4654 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4655 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4656 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4658 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4659 silc_pkcs_load_[public/private]_key.
4661 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Added silc_server_get_route (route.[ch]) to get connection
4664 data for the fastest route for given ID.
4666 * Implemented INVITE command on client and server. The command
4667 were re-defined in the SILC Protocol Specification and the
4668 implementation now complies with the specification.
4670 * Implemented PING command on client and server.
4672 * Implemented NAMES command on client and server. The server side
4673 supports currently only normal server not router server yet.
4674 Some changes to NAMES definition in SILC protocol specification.
4676 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Implemented LEAVE command on client and server.
4680 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4681 again. This change was made to the protocol as well. Server
4682 should not violate the protocol specification anymore.
4684 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4687 was tested. SOCKS4 was not but should work anyway.
