1 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Removed the non-blocking settings in WIN32 code in the
4 silc_sock_[read/write] and added SleepEx instead. Affected
5 file lib/silcutil/win32/silcwin32sockconn.c. The availability
6 of input data is now checked with FIONREAD and ioctlsocket.
8 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Call silc_schedule_task_del_by_context in the
11 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
12 Affected file lib/silccore/silcprotocol.c.
14 * Call silc_protocol_cancel for active protocols in the
15 silc_server_close_connection if the funtion
16 silc_server_free_sock_user_data has not been called.
17 Affected file silcd/server.c.
19 * Generic tasks cannot be deleted using the del_by_fd
20 task deleting function since generic tasks does not match
21 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
23 * Added a notion to SILCOPER help file that the SILCOPER works
24 only on router server, not on normal server.
26 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
28 * Added for WIN32 support for the new scheduler as well.
29 Affected file lib/silcutil/win32/silcwin32schedule.c.
31 * Fixed the SHA1 implementation to work on various platforms.
33 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
35 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
36 API. It is part of the scheduler now. Everything else is
37 as previously but some functions has changed their names.
38 Checkout the lib/silcutil/silcschedule.h for the interface.
39 Updated all applications to use the new interface. Affected
40 files are lib/silcutil/silcschedule.[ch].
42 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
44 * Found a bug in the SKE implementation. The HASH value,
45 specified by the protocol, was not computed correctly. The
46 public key of the responder was not added to the computation
47 even though it is mandatory. Affected file lib/silcske/silcske.c.
48 This unfortunately causes incompatibilities with older
51 * Added WIN32 specific network init and uninit functions:
52 silc_net_win32_init and silc_net_win32_uninit to init and uninit
53 the Winsock2. Affected file lib/silcutil/silcnet.h and
54 lib/silcutil/win32/silcwin32net.c.
56 * Set the socket always to nonblocking mode on WIN32 after
57 reading data or writing data. Affected file is
58 lib/silcutil/win32/silcwin32sockconn.c.
60 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Fixed various compilation problems under WIN32. Affected
63 files lib/silcutil/win32/silcwin32thread.c and
64 lib/silcutil/win32/silcwin32schedule.c.
66 * Removed all _internal.h #includes from public header
67 files. Internal headers must never be included from
70 Removed also the lib/silcske/payload_internal.h file.
72 * All include files that may be needed (public and some others
73 included by the public headers) by application developers are
74 now copied to the ./includes directory. It does not copy any
75 internal headers. Affected file Makefile.defines.pre and all
76 Makefile.am's under lib/ and subdirs.
78 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
80 * Do not change the ~/.silc directory's permissions automatically.
81 Affected file irssi/src/silc/core/clientutil.c.
83 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Do not cancel the protocol in silc_server_close_connection
86 it might cause recursion. Now cancelled in the function
87 silc_server_free_sock_user_data. Affected file silcd/server.c.
89 * Fixed the silc_server_remove_clients_by_server to regenerate
90 the channel keys correctly finally. Added also new function
91 silc_server_remove_clients_channels to actually do it.
92 Affected file silcd/server.c.
94 * Fixed the silc_server_new_channel to not crash by giving
95 wrong router to the new channel. Affected file is
96 silcd/packet_receive.c.
98 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
100 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
101 which is given as argument to the silc_client_alloc now.
102 It can be used to configure the client and set various parameters
103 that affect the function of the client.
105 * The USERS command in server did not check whether the channel
106 is private or secret. Affected file silcd/command.c.
108 * Added new argument to the USERS command in protocol specification.
109 The USERS command now can take the channel name as argument
110 as well. Added support for this in client and server and
111 updated the protocol specs.
113 * Completed the GETKEY command in client. It can be now used
114 to fetch also servers public key not only some clients.
115 Affected files lib/silcclient/command[_reply].c.
117 * Added silc_client_get_server to return server entry by the
118 server name. Affected files lib/silcclient/silcapi.h and
121 * Redefined the IDENTIFY command in protocol specification to be
122 more generic. It now can be used to query information about
123 any entity in the SILC Network, including clients, servers and
124 channels. The query may be based either the entity's name
125 or the ID. Added support for this in both client and server.
127 Affected files silcd/command.c and lib/silcclient/command.c
130 * Optimized the WHOIS and WHOWAS commands in the server. Removed
131 the _from_client and _from_server functions. Affected file
134 * Added silc_client_get_channel_by_id_resolve to the file
135 lib/silcclient/silcapi.h to resolve channel information by
136 its ID. Added also silc_client_get_channel_by_id that
137 does not resolve it from the server.
139 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
141 * Added SilcServerEntry context into the client library
142 to represent one server. The INFO command now allocates
143 these to save the resolved server info. For now on the
144 client library will also keep information about servers,
145 connected and resolved with INFO.
147 The INFO command now allocates the SilcServerEntry context
148 and saves the server info there. The COMMAND_REPLY in
149 the INFO now returns the parameters to application in
150 same order as defined in the protocol specification.
152 The entries are cached in the client->server_cache.
154 * The INFO command is now issued after received the Client ID
155 from the server. Affected file lib/silcclient/client.c.
157 * The CMODE_CHANGE notify may now return also an SilcServerEntry
158 to the application as the mode changer might be server.
159 It is guaranteed that NULL is not returned anymore to the
160 application. Affected file lib/silcclient/client_notify.c.
162 The ID Type is now also passed to the application so that
163 it can check whether the returned entry is SilcClientEntry
166 Added new function silc_client_get_server_by_id to return
167 the server entry by ID. Affected files are the
168 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
170 * Do not create the channel in the Irssi SILC Client when issuing
171 the JOIN command but when received the sucessful JOIN command
172 reply. Otherwise the channel might get created even though we
173 could not join it. The Affected file is
174 irssi/src/silc/core/[silc-channels.c/client_ops.c].
176 * Fixed a channel joining bug in router. The router must also
177 check the channel modes, invite and ban lists etc. when serving
178 the JOIN command sent by normal server. Affected file is
179 silcd/command.c. The router now resolves the client's
180 information from the server who sent the JOIN command if it
181 does not know it, and processes the JOIN command only after
184 * Changed the SilcCommandCb to take new argument; void *context2.
185 Affected file lib/silccore/silccommand.h
187 The second argument in the command callbacks in the server now
188 includes the SilcServerCommandReplyContext if the command was
189 called as pending command callback from the command reply.
190 Otherwise it is NULL. When called as pending the status of the
191 command reply will be checked and if it was erronous the
192 error will be sent to the original sender of the command.
193 This way the client always receives the error messages even
194 though the server was actually the one who received the error
195 when it resent the command to router, for example. Affected
196 files silcd/command[_reply].[ch].
198 * Fixed sending WHOWAS command's error message to client if
199 the requested client could not be found. It was missing.
202 * Changed the CMODE and CUMODE commands reply arguments in the
203 protocol specification. The Channel ID is now sent in both
204 of the commands to identify the channel. Implemented this
205 new feature to the client and server. Affected files
206 lib/silcclient/command_reply.c and silcd/command.c.
208 * Made better checks for invite and ban lists in the JOIN
209 command in server. Affected file silcd/command.c.
211 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
213 * The server now performs the incoming host IP/DNS lookup
214 using the silc_socket_host_lookup and thus does not block
215 the server anymore. Affected file silcd/server.c.
217 * Completed the multi-thread support for SILC Scheduler in
218 the lib/silcutil/silcschedule.c.
220 * Fixed the configure.in.pre to detect the pthread correctly
223 * Fixed a deadlock in silc_task_queue_wakeup in the file
224 lib/silcutil/silctask.c.
226 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
228 * Added new function silc_schedule_wakeup that is used in
229 multi-threaded environment to wakeup the main thread's
230 schduler. It needs to be used when a thread adds a new task
231 or removes a task from task queues. After waking up, the
232 scheduler will detect the task queue changes. If threads
233 support is not compiled in this function has no effect.
234 Implemented the wakeup mechanism to both Unix and WIN32
235 systems. Affected files are lib/silcutil/silcschedule.[ch],
236 lib/silcutil/unix/silcunixschedule.c and the
237 lib/silcutil/win32/silcwin32schedule.c.
239 * Added new function silc_task_queue_wakeup to wakeup the
240 scheduler by the specified task queue. Affected file
241 lib/silcutil/silctask.[ch].
243 * The silc_socket_host_lookup_start now wakes up the scheduler
244 after adding the timeout task. Affected file is
245 lib/silcutil/silcsockconn.c.
247 * The silc_socket_host_lookup is synchronous now if the threads
248 support is not compiled in. However, the callback is still
249 called asyncronously through the scheduler, anyway. Affected
250 file lib/silcutil/silcsockconn.c.
252 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Added new function silc_socket_host_lookup to perform
255 asynchronous IP and FQDN lookups for the socket connection.
256 Affected files lib/silcutil/silcsockconn.[ch].
258 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Added SILC_MUTEX_DEFINE to define the mutex on environments
261 that may or may not compile the mutex support in.
263 Changed the silc_mutex_alloc interface. It allocates the
264 mutex now to the sent pointer and returns TRUE or FALSE.
266 Affected file lib/silcutil/silcmutex.h.
268 * Wrote the SILC Task Queue interface to support multi-threads.
269 Affected file lib/silcutil/silctask.[ch].
271 * Wrote the SILC Scheduler to support multi-threads. Affected
272 file lib/silcutil/silcschedule.c.
274 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
276 * Implemented the SILC Mutex API and SILC Thread API for WIN32
277 in lib/silcutil/win32/.
279 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
281 * Defined SILC Mutex API and SILC Thread API and implemented
282 them for Unix. Affected files are
283 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
284 lib/silcutil/unix/silcunixmutex.c and
285 lib/silcutil/unix/silcunixthread.c.
287 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
289 * Fixed the silc_server_remove_clients_by_server's channel
290 key re-generation. The hash table handling was incorrect
291 and would not work with many channels. Affected file is
294 * Fixed some memory leaks around the server code.
296 * Rewrote the silc_server_get_users_on_channel to support IPv6
297 based Client ID's. Affected file silcd/server.c.
299 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
300 specification. However, a separate document must be written
301 to define the detailed signing procedure and the payload
302 associated with the flag. Defined the flag to the
303 lib/silccore/silcchannel.h as well.
305 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
307 * Changed the dynamic tables to static size tables in the
308 lib/silccrypt/silchmac.c.
310 * Removed GCC dependencies from the code. A patch by cras.
312 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
314 * Do not show the error "Error receiving packet bla bla"
315 in server if it really was not an error (-2 means that reading
316 is pending). Affected file silcd/server.c.
318 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
320 * Fixed a possible crash in silc_server_remove_clients_by_server
321 in silcd/server.c. Fixed there also some memory leaks.
323 * Fixed the silc_idlist_replace_client_id. It could replace
324 wrong key in the hash table. Affected file silcd/idlist.c.
326 * Do not check whether there are global users on the channel
327 if the channel->global_users is FALSE. Affected functions
328 silc_server_remove_from_one_channel and
329 silc_server_remove_from_channels in silcd/server.c. Also,
330 do not check if the removed client is local as we can be
331 sure that global client was not removed from the channel
332 and checking for global users is not needed.
334 * The silc_server_remove_clients_by_server now re-generates
335 the channel keys correctly for those channels that had
336 clients removed from them. Affected file silcd/server.c.
338 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
340 * Found the reason of random crashes in the server. We weren't
341 ignoring the SIGPIPE signal (which can be sent in write())
342 and it crashed the server. Affected file silcd/silcd.c.
344 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Assure that sock->user_data is not NULL in the function
347 silc_server_packet_send in silcd/packet_send.c.
349 * Disconnect the remote connection if it could not be added
350 to any ID lists in the server. The affected file is
353 * Check in silc_server_packet_send[_real/dest] that the
354 socket is not disconnecting and ignore the data if it is.
355 Affected file silcd/packet_send.c.
357 * Define inline to __inline on native WIN32 compilation.
358 Affected file includes/silcwin32.h.
360 * Added some explicit type casts for inline code since MSVC
361 require them. Affected files lib/silcutil/silcbuffer.h,
362 lib/trq/silcdlist.h and lib/trq/silclist.h.
364 * Print warning in log files from now on if the packet
365 decryption fails. Affected file silcd/server.c.
367 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Changed the `say' client operation's interface to accept
370 new `type' argument to indicate the type of the message sent
371 by the library. The application may filter the library's
372 messages according the type. The affected file is the
373 lib/silcclient/silcapi.h.
375 * Added two new functions to lib/silcclient/silcapi.h:
376 silc_client_del_client and silc_client_del_client_by_id.
377 Affected file lib/silcclient/idlist.c.
379 * Moved the clientincludes.h from includes/ to silc/ and
380 serverincludes.h from includes/ to silcd/.
382 * The modes for the CMODE and CUMODE are now passed as
383 uint32 for application with COMMAND_REPLY. The affected
384 file is lib/silcclient/command_reply.c.
386 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
388 * /WHOIS without arguments shows client's own information.
389 Affected file lib/silcclient/command.c.
391 * Changed PING to not accept any arguments. The specs
392 says that client can ping only the connected server so
393 requiring an argument is not needed. Affected file is
394 lib/silcclient/command.c.
396 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
398 * Fixed a fatal bug in private message sending and reception
399 encryption and decryption when using private message keys.
400 The implementation was incorrect and did not follow the
401 specification. It causd that some of the message were
402 lost since it did not use the sending and receiving keys
403 as the protocol suggests. This has been fixed and will cause
404 incompatibilities with older clients when sending private
405 message encrypted with private message keys. Affected files
406 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
407 and various other in Irssi SILC Client.
409 Added `responder' boolean argument to the functions
410 silc_client_add_private_message_key[_ske] to indicate when
411 the key is added as responder or initiator of the key
414 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
416 * Removed the silc_ske_check_version function and created
417 a SilcSKECheckVersion callback. Added also a function
418 silc_ske_set_callbacks that is now used to set all SKE
419 callbacks. The callback functions are not given to
420 the SKE functions anymore, but this function is used to
423 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
425 * Added `silc_version' argument to the silc_client_alloc
426 to define the version of the application for the library.
427 The library will use the version string to compare it
428 against the remote host's (usually a server) version
429 string. Affected file lib/silcclient/silcapi.h
431 * Added the KE protocol context to Key Agreement context
432 in client library so that we can abort the SKE if it
433 is in process when we get timeout. Affected file is
434 lib/silcclient/client_keyagr.c.
436 * Do not resolve the client ID forever if it returns in the
437 first time that such client does not exist. This was done
438 for example with private message. Affected file is
439 lib/silcclient/client_prvmsg.c.
441 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Do not add regex.h for WIN32. The affected file
444 includes/silcincludes.h.
446 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
447 not work yet 100%. It generates the DLL's automatically
448 when compiling with --with-win32 under cygwin.
450 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
452 * lib/contrib/regex.c is not compiled on WIN32.
454 * Added silc_net_get_socket_opt function to the
455 lib/silcutil/silcnet.h.
457 * Added includes/silcwin32.h for WIN32 specific includes
460 * Do not use ptime structure or any of the posix process
461 functions on WIN32 in lib/silccrypt/silrng.c.
463 * Added silc_gettimeofday to provide generic function
464 for struct timeval on all platforms. Added the function
465 to lib/silcutil/silcutil.h.
467 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Moved the lib/silccore/silcsockconn.[ch] to the utility
470 library as they clearly belong there. As a plus side we
471 can make the actual socket connection routines platform
474 Added also new generic function silc_socket_read and
475 silc_socket_write (that used to be silc_packet_[read/write].
476 The implementation of these are platform specific.
478 * Added WIN32 specific routines of silc_socket_[read/write]
479 to lib/silcutil/win32/silcwin32sockconn.c.
481 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Added preliminary support for native WIN32 compilation under
484 cygwin (using the -mno-cygwin option for GCC) to the
485 ./configure.in.pre. The --with-win32 now prepares the
486 compilation for native WIN32.
488 * Rewrote the SILC Scheduler interface in the file
489 lib/silcutil/silcschedule.h. The scheduler is now context
490 based and does not have anymore any global static scheduler.
491 Moved the Unix scheduler to the lib/silcutil/unix/ directory
492 and created lib/silcutil/win32 directory for WIN32 based
495 * Added Unix specific network routines to the
496 lib/silcutil/unix/silcunixnet.c and the old
497 lib/silcutil/silcnet.c includes now only generic routines.
499 Added WIN32 specific network routines to the
500 lib/silcutil/win32/silcwin32net.c.
502 * Added Unix specific utility functions from the
503 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
505 * Added WIN32 SILC Scheduler to the file
506 lib/silcutil/win32/silcwin32schedule.c. The code is of course
509 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * Do not handle JOIN notify in the server if the target client
512 is not registered (idata->registered == FALSE). The affected
513 file is silcd/packet_receive.c.
515 * Update the nickrec->founder in event_cumode in the Irssi SILC
516 client. Affected file irssi/src/silc/core/silc-channels.c.
518 * Fixed the CUMODE_CHANGE notify handling in the server when
519 server and router are announcing their clients on channels.
520 Now the mode changes are saved and notified correctly. The
521 affected file is /silcd/packet_receive.c.
523 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
524 They really did not replace the cache entry in the ID Cache.
525 Now they do that. Affected file silcd/idlist.c.
527 * Fixed the KICK notify handling in the Irssi SILC client to
528 update the channel records so that the kicked client does not
529 appear to be on the channel. The affected file is
530 irssi/src/silc/core/silc-channels.c.
532 * Always update the conn->current_channel when executing command
533 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
535 * Fixed the KILL notify handling in Irssi SILC client to remove
536 the killed client on all channels.
538 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Fixed the silc_parse_command_line to remove extra spaces
541 from the start and end of the arguments. Affected file is
542 lib/silcutil/silcutil.c.
544 * Cancel and free any active protocol in the function
545 silc_server_close_connection. Affected file silcd/server.c.
547 * Cancel and free any active protocol in the function
548 silc_client_close_connction. Affected file is
549 lib/silcclient/client.c.
551 * Do not execute the KILL command for clients that are in
552 history (ie. they are not in the network). Affected file is
555 * Fixed KILL notify handling, client does not crash anymore.
556 Affected file irssi/src/silc/core/silc-channels.c.
558 * Reduced the default packet buffer size from 2048 to 1024 in
559 lib/silccore/silcpacket.c.
561 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
562 counter to the SKE context that is incresed when the SKE library
563 performs async operation outside the library. If the outside
564 process frees the SKE context and FREED status will be set
565 and the library will detect after the sync operation that the
566 libary is freed. The affected files are
567 lib/silcske/silcske[_status].[ch].
569 * Resolve the client entry information in the function
570 silc_client_channel_message to assure that NULL pointer is not
571 passed as client entry to the application. */
573 * Fixed the task timeout calculation to assure that there is
574 never negative timeouts. The affected file is
575 lib/silcutil/silcschedule.c.
577 * Fixed the channel user mode notification sending in server.
578 It was sent point-to-point to the router (or to server by router)
579 but it needs to be destined to a channel. The routines now
580 supports sending the channel user mode notifys to the channels
581 when announcing clients and channels. Affected files are
582 silcd/server.c and silcd/packet_receive.c.
584 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
585 It did not actually replace the old channel entry in the cache.
586 Affected file lib/silcclient/client_notify.c.
588 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Fixed a possible crash in silc_packet_send_prepare. It now
591 assures always that there is enough space in the buffer and
592 at the tail area of the buffer (for MAC).
594 Fixed the inbound buffer reallocation in silc_packet_read.
595 It was old code and did not handle the reallocation correctly.
598 The affected file is lib/silccore/silcpacket.c.
600 * Fixed buffer overflow in silc_parse_nickname in the file
601 lib/silcutil/silcutil.c.
603 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
605 * make install generates new server keys only if there is not
608 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
611 Added check that if the NOREPLY is set then we will not send
612 the away message. This avoids infinite loop of away messages
613 if both clients are away. The affected file is
614 lib/silcclient/client_prvmsg.c.
616 * Fixed client crash if /NICK was given without arguments.
617 Affected file lib/silcclient/command.c.
619 * Server does not send the invite list in INVITE command back
620 to the client if the list was not altered. Added this notion
621 to the protocol spec as well. Affected file silcd/command.c.
623 Fixed possible crash in INVITE command by checking the
624 value of silc_server_get_client_route command.
626 * Fixed the INVITE notify type handling. The arguments are now
627 taken in correct order and client does not crash. The affected
628 file is irssi/src/silc/core/silc-channels.c.
630 Removed the "Inviting xxx to channel" message from the
631 client library away and let the application handle it.
632 Affected file lib/silcclient/command.c. Added that message
633 to Irssi SILC client's message formats.
635 * Fixed CMODE command crash in client. It now checks the
636 amount of arguments correctly and does not crash. The affected
637 file is lib/silcclient/command.c.
639 * Do not create new channel automatically in silc_channels_join
640 but check whether the channel by that name already exists.
641 Affected file irssi/silc/core/silc-channels.c.
643 * Do not send the SERVER_SIGNOFF to router if the disconnected
644 entity was the router. Affected file silcd/server.c.
646 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
647 SILC client as it was missing from there.
649 Added the handling of the KICK notify to the Irssi SILC client
650 as it was missing. Added "you have been kicked" message to
651 Irssi SILC client's message modules formats.
653 Added the handing of the KILL notify to the Irssi SILC client
654 as it was missing. Added the kill message module formats
657 The affected file is irssi/src/silc/core/silc-channels.c.
659 * The router did not save the channel mode the server announced.
660 Affected file silcd/packet_receive.c.
662 * Fixed a possible crash in INFO command in server. If the
663 server did not provide the server info it crashed. Affected
664 file silcd/command.c.
666 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Fixed the GETKEY command in the server to check also the
669 global list. Otherwise the GETKEY would not work correctly
670 in normal SILC server. Affected file silcd/command.c.
672 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Fixed GETKEY crash, it crashed if the command did not succseed.
676 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
678 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
679 is now real and not just an macro interface to GMP.
681 Removed the entire GMP from the source tree and imported new
682 NSS MPI library instead. Reason for removing GMP is that it is
683 extremely large and compiles extremely slow. The NSS MPI
684 is only a few files and compiles in less than 10 seconds.
685 The speed is also about the same as GMP. The MPI is imported
688 If the system has GMP installed we will still use the GMP.
689 If it is not then the NSS MPI will be compiled.
691 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Merged a long nickname (127 characters long) crash bugfix from
694 Irssi CVS tree. Affected file irssi/src/core/misc.c.
696 * Merged a freed memory reference bugfix from Irssi CVS tree.
697 Affected file irssi/src/core/commands.c.
699 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Added the server's public key sving and verification to the
702 server when performing the SKE. This was missing and the
703 remote server's (or router's) public key was accepted without
704 checking whether we have it previously or trust it at all.
705 Affected file silcd/protocol.c.
707 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Check in the silc_server_timeout_remote if protocol is active
710 and make sure that the protocol's final callback is called so
711 that all memory if freed. Affected file silcd/server.c.
713 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * silc_server_whois_send_reply crashed the server if the nickname
716 was 127 characters long. Affected file silcd/command.c.
718 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Added sanity check to the silc_server_new_client. If the hostname
721 is provided inside username then check that the provided hostname
722 really is the same as the resolved one. If the hostname was not
723 resolved then check it from the public key. Affected file is
724 silcd/packet_receive.c.
726 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
727 if the server disconnected us and the connection is not valid
728 anymore. Affected file irssi/src/silc/core/silc-channels.c.
730 * Moved the silc_client_[chmode|chumode|chumode_char] away from
731 the library to the lib/silcutil/silcutil.[ch].
733 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Close log file after open. Affected file
736 lib/silcutil/silclog.c.
738 * Check whether sock == NULL in silc_client_send_packet and return
739 if it is. Affected file lib/silcclient/silcclient.c.
741 * Check rec->entry == NULL in the Irssi SILC Client before
742 sending the channel message. Affecte file is
743 irssi/src/silc/core/silc-servers.c.
745 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Merged a splitted window bugfix from Irssi CVS tree. The
748 affected file is irssi/src/fe-text/textbuffer-view.c.
750 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
751 It did not print nickname.
753 * Improved the distributions system a bit.
755 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
758 irssi/src/fe-text/gui-window.c.
760 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
761 to in-active server. The affected file is
762 irssi/src/silc/core/client_ops.c.
764 * Resolve the client in USERS command reply if the entry does
765 not have username resolved. The affected file is
766 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
767 command to WHOIS command to really resolve stuff. The USERS
768 is not used any more in any critical section so WHOIS can
769 be used even though it might be slower than IDENTIFY.
771 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
774 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Changed the protocol API a bit more consistent in the
777 lib/silccore/silcprotocol.[ch].
779 * Changed the following headers to ROBODoc format:
781 lib/silccore/silcpayload.h
782 lib/silccore/silcprotocol.h
783 lib/silccore/silcsockconn.h
785 All core library headers are now formatted.
787 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Fixed a bug in Irssi SILC client; do not show that you are
790 server/router operator if you really are not. Affected file is
791 irssi/src/silc/core/client_ops.c.
793 * Renamed silc_command_free_payload to silc_command_payload_free.
794 Affected file lib/silccore/silccommand.h
796 * Added silcmath.h to include the prototoypes of various routines
797 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
800 * Changed the following headers to ROBODoc format:
802 lib/silccore/silcchannel.h
803 lib/silccore/silccommand.h
804 lib/silccore/silcid.h
805 lib/silccore/silcidcache.h
806 lib/silccore/silcmode.h
807 lib/silccore/silcnotify.h
808 lib/silccore/silcpacket.h
809 lib/silcmath/silcmath.h
811 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
813 * Added checking to the server code not to start the server if
814 ciphers and stuff are not configured properly. Affected files
815 silcd/serverconfig.[h] and silcd/server.c.
817 * Changed the layout of the header files of the public interfaces
818 in the SILC libraries. The new layout supports ROBODoc
819 documentation tool (and some others) so that it is easy to create
820 a library reference manual. All the other headers and source
821 code must still follow the CodingStyle document. Also source
822 code must not include these ROBODoc stuffs, only the headers.
823 Furthermore, all public interface headers must now be named
824 by using `silc' prefix, example: silcapi.h, silccipher.h.
825 Some files were renamed due to this. All the other headers
826 must not be used as public interfaces. I will update the
827 CodingStyle document later. Changed following headers, so far:
829 lib/silcclient/silcapi.h
830 lib/silccore/silcauth.h
831 lib/silccore/silcprivate.h
832 lib/silccrypt/silcdh.h
834 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Removed silc_client_packet_send_flush from the client library
839 as it is not needed. Affected file lib/silcclient/client.[ch].
841 * Added printing of message of unresolved authentication method
842 to the Irssi SILC client. Added it to the module formats.
843 Removed the same message from the client library.
845 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Added new distribution feature, DISTLABEL. Every distribution
848 can define own preprocessor label that can be used in the
849 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
850 file distributions, acconfig.h.pre and prepare.
852 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Added Makefile.defines_int to include the actual definitions
855 for Makefile.defines.in. Tested the new distribution system,
856 created distributions and tested installation.
858 * Added AWAY message printing to the Irssi SILC client. Added
859 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
861 * Added SCONNECT command to call the SILC's CONNECT command.
862 Cannot use CONNECT directly since Irssi uses that internally.
863 Affected file irssi/src/silc/core/silc-servers.c.
865 Added ACTION local command. It is same as ME command but takes
866 the channel as mandatory argument.
868 Rewrote some of the Irssi's help files to suite for SILC
871 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * Added Makefile.defines[.in] that should for now on be included
874 in all Makefile.am file in the source tree. That file includes
875 all common compilation definitions for SILC source tree.
877 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Minor changes to the ./prepare script to change the package
880 name according the distribution name to the configure.in.
882 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Created new distribution system. Added file `distributions'
885 that defines all the distributions that can be created out of
886 the SILC source tree. The ./prepare script now reads that
887 file to determine how to prepare the distributions. The
888 first argument to the ./prepare is the name of the distribution
889 and second is the version of the distribution. If given
890 without arguments it creates the default (toolkit) distribution
891 with the default version (defined in ./prepare).
893 All Makefile.am files that are subject to the distributions
894 are now named as Makefile.am.pre. These are ./Makefile.am
895 and lib/Makefile.am. Others may be changed later.
897 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Added invite list, ban list, some key management and connection
900 error message printing to module formats in the Irssi SILC client.
902 * Added new silc_client_set_away_message to set the away message
903 that is back to the person who sent private message. The
904 affected file lib/silcclient/silcapi.h and the
905 lib/silcclient/client_prvmsg.c.
907 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Fixed the private message sending in the Irssi SILC client,
910 added local command KEY to the Irssi SILC client.
912 Added key management and key agreement message formats to the
913 irssi/src/fe-common/silc/module-formats.[ch].
915 Added USERS (alias WHO) printing, server/router operator
916 indication and LIST command printing to the module formats.
918 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * Fixed channel joining notify handling, cumode notify handling
921 from Irssi SILC client.
923 * Added SILC specific module-formats to the Irssi SILC client so
924 that SILC specific message hilighting, colors etc is possible.
925 Affected file irssi/src/fe-common/silc/module-formats.[ch].
927 Added channel mode, channel user mode, actions, notices,
928 whois and whowas printing to the the module-formats.c.
930 * Fixed a bug in channel deletion in the server. The channel
931 is not left to the cache even if the channel founder auth mode
932 is set when there are no users anymore on the channel. Affected
935 * The silc_net_localhost now resolves the entire hostname including
936 the domain name. Affected file lib/silcutil/silcnet.c.
938 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Changed the ask_passphrase client operation to be ascynchronous.
941 It has now a completion callback and a context that the
942 application must call after it has got the passphrase from
943 the user. Affected files lib/silcclient/silcapi.h,
944 lib/silcclient/protocol.c, lib/silcclient/command.c and
947 Added SilcAskPassphrase callback that the application calls
948 to deliver the passphrase to the library.
950 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
951 The public key verification and especially a certificate
952 verification is asynchronous procedure.
954 Added new SILC_SKE_STATUS_PENDING status to indicate the
955 request is pending and a callback will be called to finalize
958 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
959 indicate that remote end did not send its public key (or
960 certificate), even though we require it. Added check for this
961 condition in the SKE. This was a security bug, now fixed.
963 Defined new SilcSKEVerifyCbCompletion callback that is called
964 when the verification process is completed.
966 The affected files lib/silcske/silcske_status.h and
967 lib/silcske/silcske.[ch].
969 * Changed the verify_public_key client operation to be async
970 as well. Defined SilcVerifyPublicKey callback that is used to
971 indicate the success of the public key verification process.
973 Changed the server and client to use the new async client
976 * Changed the Irssi SILC client's internal scheduler to be called
977 twice as many times as it used to be. As a result the client
978 should be a bit faster now. Affected file is
979 irssi/src/silc/core/silc-core.c.
981 * Added support to Irssi SILC client of asynchronous public key
982 verification and passphrase inquiry. Affected file is
983 irssi/src/silc/core/silc-core.c.
985 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Do not say "You have left channel %s" in client library.
988 Moved it to the application. Affected files are
989 lib/silcclient/command.c and silc/client_ops.c.
991 * Fixed silc_client_get_clients. Command context was not
992 duplicated and was freed memory in the callback. Affected
993 file lib/silcclient/idlist.c.
995 * Do not say "you are now talking..." on JOIN command in the
996 client library. The appliation must handle it.
998 * Do not say ".. changed topic to" in command reply in the
999 client libary. The application must handle it.
1001 * Fixed TOPIC command sending in the client library.
1003 * Fixed a memory leak in silc_client_command_free in the file
1004 lib/silcclient/command.c.
1006 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1008 * Imported a modified version of Irssi client to the source tree.
1009 The Irssi will be used to create a new client called
1010 Irssi SILC. Imported to irssi/.
1012 Added silc_core_init_finish function to the Irssi. Affected
1013 file irssi/configure.in.
1015 A lot changes in the Makefile.ams around the irssi tree.
1017 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Do not rehash if the new size is same as the old size of the
1020 hash table, in the silc_hash_table_rehash*. The affected file
1021 lib/silcutil/silchashtable.c.
1023 * Replaced hash_table_del_by_context calls from the server
1024 (when channel->user_list and client->channels) to the
1025 hash_table_del as it is sufficient and faster.
1027 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Added silc_hash_table_list, silc_hash_table_get and the
1030 SilcHashTableList structure to provide an alternative way to
1031 traverse the hash table. The affected files are
1032 lib/silcutil/silchashtable.[ch].
1034 * Changed the server's idlist routines to use the hash table
1035 routines to optimize the code.
1037 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1039 * Replaced the client entry's `channel' list and channel entry's
1040 `user_list' list to hash tables for optimized lookup. Changed
1041 the code to use the hash table interface around the code.
1042 Affected file lib/silcd/idlist.[ch].
1044 * Added `auto_rehash' boolean argument to the function
1045 silc_hash_table_alloc to indicate whether the hash table should
1046 auto-rehash when it thinks is appropriate time. It will
1047 increase the hash table size if the there is twice as much
1048 entries in the table than the size of the table, and will
1049 decrease the size if there are twice as less entries than
1050 the size of the table.
1052 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1056 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * silc_idcache_purge_by_context deletes the entry now by context
1059 as it is supposed to do. Affected file lib/silccore/idcache.c.
1061 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1062 client is not anymore valid (WHOWAS givens the info) and not
1063 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1065 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Removed the `data' and `data_len' arguments from the ID Cache
1068 interfaces and added `name' argument. ID Cache does not handle
1069 anymore the binary data only a names associated with given ID.
1071 * When hashing a Client ID with silc_hash_id the entire ID is
1072 not hashed anymore, instead only the hash of the Client ID is
1073 hashed. This way we can access the Client ID from the cache
1074 with Client ID but with the hash of the ID (which is a hash of
1075 the nickname) as well without any difference in performance.
1077 Added also silc_idcache_find_by_id_one_ext to do one on one
1078 searching when we have the actual ID. Added also function
1079 silc_hash_client_id_compare. The affected files are
1080 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1082 * When hashing the name associated with a ID it is always done
1083 in lowercase. This way we can access the cache without worrying
1084 about case-sensitivity, even though, for example nicknames are
1087 * Fixed a bug in server with channel message sending. It put
1088 wrong ID type as destination ID. The affected file
1089 silcd/packet_send.c.
1091 * silc_idcache_del_by_context now deletes from all hash tables
1092 by context. Affected file lib/silccore/idcache.c.
1094 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Changed the client library to use the new ID Cache interface.
1097 Changes around the source tree.
1099 * Added silc_hash_table_rehash_ext to rehash with specific
1100 hash function. Affected file lib/silcutil/silchashtable.[ch].
1102 * Added silc_hash_string_compare to compare two strings in the
1103 hash table. Affected file lib/silcutil/silcutil.[ch].
1105 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1107 * Added new function silc_idcache_del_by_context into the
1108 lib/silccore/idcache.[ch].
1110 * Changed the server's ID list routines to use the new ID Cache
1111 interface. Changes around the source tree.
1113 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Added silc_hash_table_del[_by_context]_ext functions in to the
1116 lib/silcutil/silchashtable.[ch].
1118 Removed silc_hash_table_find_all* routines and added new
1119 silc_hash_table_find_foreach to replace them.
1121 Added silc_hash_table_replace_ext function as extended
1122 replacing function. Separated the simple hash table interface
1123 from the extended hash table interface in the file
1124 lib/silcutil/silchashtable.h.
1126 * Fixed minor bugs and changed it to use some of the new
1127 hash table functions in lib/silccore/idcache.c
1129 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Added new function silc_hash_table_find_all to return all keys
1132 in the hash table by the specified key. As the hash table is
1133 collision resistant it also makes it possible to have several
1134 duplicate keys in the hash table. This function may be used to
1135 find all of the keys from the hash.
1137 Added user_context arguments to the SilcHashFunction,
1138 SilcHashCompare and SilcHashDestructor to deliver user specified
1141 Added new fuctions silc_hash_table_find[_all]_ext to do
1142 extended lookup with specified hash and compare functions and
1143 specified user contexts.
1145 Added new function silc_hash_table_add_ext to add the key
1146 with specified hash function and user context.
1148 Added new function silc_hash_table_foreach to traverse all
1149 entrys in the hash table. Added SilcHashForeach callback
1152 Added new function silc_hash_table_del_by_context to delete
1153 the entry only if the context associated with the key matches.
1155 Affected files are lib/silcutil/silchashtable.[ch].
1157 * Removed silc_hash_[server/client/channel]_id and added just
1158 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1159 silc_hash_id_compare to compare two ID's using as the hash table
1160 comparison function. Added also silc_hash_data to hash
1161 binary data and silc_hash_data_compare to compare it.
1163 * Removed silc_idlist_find_client_by_hash as it is not needed
1164 anymore. Affected file silcd/idlist.[ch].
1166 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1167 to use internally the SilcHashTable. The new ID Cache is a lot
1168 faster than the old one. Some of the ID Cache interface was also
1169 rewritten and obsolete and stupid functions were removed.
1171 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Added entry_count field to the SilcHashTable to keep the number
1174 of the entries in the table. Implemented the function
1175 silc_hash_table_rehash. Added new function
1176 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1178 Fixed a minor bug in silc_hash_table_free.
1180 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1181 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1182 into the lib/silcutil/silcutil.[ch].
1184 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Implemented a collision resistant hash table into the
1187 lib/silcutil/silchashtable[ch]. See the header and the source
1188 for the SilcHashTable API.
1190 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1192 * Merged dotconf version 1.0.2 into lib/dotconf.
1194 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Do not compile anything in lib/silcsim/* if the SIM support
1197 is not enabled. The tree should now compile without problems
1200 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Compiled the SILC under cygwin. Compiled and tested briefly
1203 without problems. More tests needed. The SIMs didn't compile
1206 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1208 * Fixed possible crash in silc_get_username in the
1209 lib/silcutil/silcutil.c.
1211 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Fixed a va_arg in silc/client_ops.c.
1215 * Oops, RC5 routines were named AES and caused some problems
1216 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1218 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Added new SilcIDIP structure into the lib/silccore/id.h and
1221 replaced the old `ip' fields from all SILC ID's to that type.
1222 This is a step towards IPv6 support.
1224 The silc_id_get_len takes now the ID as an extra argument.
1225 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1226 both IPv4 and IPv6 based ID's.
1228 The affected files are lib/silccore/id.[ch] and other files
1229 around the tree using these routines.
1231 * Removed the ID length arguments in server from various
1232 silc_server_send_notify_* routines -> they are not needed
1235 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Fixed memory leak in silc_encode_pem_file in the file
1238 lib/silcutil/silcutil.c.
1240 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Check minor version as well in the SKE. Affected files are
1243 silcd/protocol.c and lib/silcclient/protocol.c.
1245 * Added --identifier option to the server so that an identifier
1246 can be when creating the public key for the server. Affected
1247 file is silcd/silcd.c.
1249 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1250 lib/silccrypt/silcpkcs.c.
1252 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Register default ciphers and stuff when using -C option with
1255 the server. Affected file sildc/silcd.c.
1257 * Put back the servers public key filename format, it is better
1258 than the new one. For now, the client keys are saved with the
1259 new filename format. The affected file silc/client_ops.c.
1261 * Implemented the Cipher API for the rest of the ciphers that
1262 did not implement it or implemented it the wrong way.
1264 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Register default ciphers and stuff when using the -S option
1267 in the client. Affected file silc/silc.c. Same also when
1268 creating new key pair with -C option.
1270 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1272 * Fixed the silc_verify_public_key client operation function to
1273 save the public keys differently. The fingerprint is now
1274 used as filename and not the hostname. This way also the
1275 client keys are saved uniquely and not with hostnames. The
1276 affected file is silc/client_ops.c.
1278 * Trimmed the silc_hash_fingerprint function to remove extra
1279 whitespaces from the end of the fingerprint. The affected
1280 file is lib/silccrypt/silchash.c.
1284 * Added silc_cipher_register_default function to register all
1285 default ciphers. It can be used when configuration files
1286 does not exist and the application does not want any specific
1287 ciphers in any specific order.
1289 The SilcDList is now used as silc_cipher_list dynamically
1290 allocated cipher list. Removed the static list all together
1291 and now all ciphers must be allocated to the dynamic list.
1292 The silc_cipher_alloc routine was changed to check only the
1295 All silc_cipher_* routines that used to return int returns
1298 The affected files lib/silccrypt/silccrypt.[ch].
1300 * The same thing was done to silc_hash_* as for silc_cipher_*
1301 routines. Affected files lib/silccrypt/silchash.[ch].
1303 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1304 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1305 Added also silc_pkcs_[un]register[_default] functions.
1306 Removed the data_context from the PKCS API.
1308 * Added silc_hmac_register_default function to register default
1309 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1310 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1311 to unregister all hmacs at once.
1313 * Register the default ciphers, hash functions, PKCSs and HMACs
1314 if client's configuration file does not exist. The affected
1317 * The client did not load the hash functions from the SIM
1318 modules at all. Added support for this. Affected file is
1319 silc/clientconfig.c.
1321 * When decoding public key with silc_pkcs_public_key_decode, check
1322 the supported algorithm only if PKCS are registered. Affected
1323 file lib/silccrypt/silcpkcs.c. The same was done with the
1324 silc_pkcs_private_key_decode.
1326 * Fixed the SILC List routines to keep the list always in order.
1327 It used to change the list's order when traversing the list but
1328 not it preserves the order. Affected file lib/trq/silclist.h.
1330 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Added the client library to use the SilcSocketConnection's
1333 reference counter (by silc_socket_dup) to prevent the bug that
1334 the socket object may be freed underneath async operation.
1336 * The name resolv library checking fixes in the configure.in.pre.
1339 * Created new version of the protocol drafts for future
1340 development. The -03 drafts are the ones that will be changed
1341 in the trunk now and the -02 will remain as they are.
1343 * Send list of CUMODE notifys to the router when announcing
1344 the channel users to the router. Affected file silcd/server.c.
1345 If the router receiving channel founder CUMODE for a channel
1346 that already has channel founder it will send CUMODE notify
1347 to the sender to remove the channel founder rights from the
1348 announced client. Affected file silcd/packet_receive.c.
1350 * The CUMODE notify may now use Server ID as well as the entity
1351 who changes the mode. Updated protocool specs.
1353 * Updated INSTALL and README files.
1355 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * New web pages in the http://silc.pspt.fi. The pages was
1362 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Implemented the [DenyConnectin] config section in the server.
1365 Added silc_server_config_denied_conn to check whether incoming
1366 connection is denied. Affected file silcd/serverconfig.[ch].
1368 * Do not check the ports when checking the incoming configuration
1369 data if the port is 0, meaning any. Affected file is
1370 silcd/serverconfig.c.
1372 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Fixed buffer overflow in silc_string_compare in the file
1375 lib/silcutil/silcutil.c.
1377 * Fixed double free in silc_server_command_leave in the file
1380 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1382 * Fixed the version checking in the server. Affected file is
1385 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * Fixed the configuration data fetching when accepting new
1388 connections in the server. Affected file silcd/server.c.
1390 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Added `sender_entry' argument to the function
1393 silc_server_packet_relay_to_channel so that we can check
1394 whether some destination actually belongs to the same route
1395 the sender belongs (ie, we must not resend the packet to the
1396 sender). Affected file silcd/packet_send.[ch].
1398 * Added `servername' field to the SilcClientEntry in the server
1399 to hold the name of the server where client is from. Affected
1400 file is silcd/idlist.h.
1402 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1404 * Moved the channel message encrypting in the router betwen
1405 router connections from silc_server_channel_message to the
1406 silc_server_packet_relay_to_channel since we want to check
1407 whether we have anybody channel before encrypting anything.
1408 Affected files silcd/packet_[receive/send].c.
1410 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Fixed the [AdminConnection] server config section to support
1413 multiple entries. Affected file silcd/serverconfig.c.
1415 * Added support into the server to check the validity of the
1416 incoming connection before executing any KE or authentication
1419 * The connection configuration is now saved to the KE and
1420 connection auth protocol contexts and not fetched anymore in
1421 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1423 * The local hosts listenning address and port is also resolved
1424 now when starting the server. We want to have the socket object
1425 to include the real address and port for the listener. Added
1426 new function silc_net_check_local_by_sock into the files
1427 lib/silcutil/silcnet.[ch].
1429 * Fixed a broadcast bug in server -> do not broadcast if we
1432 * Fixed a routing bug. Do not route broadcast packets ever.
1433 Broadcast packets must be processed always and not routed since
1434 they may be destined to some other host than yourself and thus
1435 would get routed without no good reason. Affected file is
1438 * Added function silc_server_config_is_primary_route to check
1439 whether primary router connection has been configured (a router
1440 configuration that we are initiating). If there is not, we
1441 will assume that there is only two routers in the SILC network
1442 and we will use the incoming router connection as our primary
1443 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1445 * Changed the order of the broadcasting. Broadcast _after_ the
1446 packet has been processed not before. Affected file is
1449 * Fixed a [ClientConnection] parsing bug. The port was never
1450 parsed correctly thus resulting to port 0. Affected file
1451 silcd/serverconfig.c.
1453 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1454 argument and did not set the broadcast packet flag. Affected
1455 file silcd/packet_send.c. Fixed same bug in the function
1456 silc_server_send_notify as well.
1458 * If we receive NEW_ID packet for our own ID in the server, ignore
1461 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Removed the nickname from the Private Message Payload.
1466 Updated the code and the protocol specs.
1468 * Updated protocol specs for submitting to the IETF.
1470 * Tweaked the Random Number Generator a bit. Affected file
1471 lib/silccrypt/silcrng.c. Exported a new function
1472 silc_rng_[global]_add_noise which can be used to add more
1475 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Do not parse packets with different timeout when protocol
1478 is active -> may cause problem with rekey. Affected file
1481 * When server receives signoff notify it must not create
1482 new channel key if the client is on any channels since the
1483 sender of the signoff notify will create it.
1485 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Added printing of error messages during SKE protocol from the
1488 failure packet sent by server during SKE. Affected file
1491 * Removed the client's failure_callback handling with timeout
1492 and handle it immediately when received.
1494 * The SKE library returned wrong type in SUCCESS and FAILURE
1495 packets. They must be 32 bit MSB not 16 bit MSB.
1497 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Ok, rewrote the logic of the re-key and now it seems to work.
1500 I tested it on high traffic with frequent re-keys without
1501 problems. Added hmac_receive (and renamed hmac to hmac_send)
1502 in SilcClientConnection in lib/silcclient/client.h and
1503 in SilcIDListData in silcd/idlist.h. Also, removed the
1504 SilcPacketParserContext's cipher and hmac fields as they are
1505 not needed anymore and actually caused some problems when
1506 the ciphers and hmac's changed underneath the packet parser.
1508 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * If re-key protocol is active then process the incoming packets
1511 synchronously since we must assure that icoming packets encrypted
1512 with the old key is processed before the new keys is set to
1513 use. This is true other packets than for REKEY packets.
1514 Affected file silcd/server.c. The same was done to client library
1515 as well, affected file lib/silcclient/client.c.
1517 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1519 * Fixed bug in client and server to accept the force send if
1520 the packet is send from silc_[server/client]_packet_process
1521 function. Otherwise the packets are never delivered, oops.
1523 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Disable force sending of packets when REKEY protocol is active.
1526 We must assure that no packet is sent directly when rekey is
1527 performed. All packets must be sent through packet queue.
1528 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1529 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1530 function is silc_[server/client]_packet_send_real to check
1533 * Replaced the SIM paths from example config files to
1534 /usr/local/modules. Also, make install creates now
1535 /usr/local/silc/logs directory to hold all the SILC server
1538 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * Made the configure.in.pre work on Solaris. Patch by salo.
1542 * Made all ciphers compatible with non-x86 machines. Defined
1543 CBC mode macros into lib/silccrypt/ciphers_def.h.
1545 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Fixed the make install.
1549 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * When MAC computation fails the silc_packet_decrypt returned 0
1552 even though it was supposed to return -1. Fixed this. The
1553 affected file is lib/silccore/silcpacket.c.
1555 * Do not replace the config files in /etc/silc (in make install)
1556 if they already exist. Affected file ./Makefile.am.
1558 * Do not send re-key packets immediately but through packet queue.
1559 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1561 * Changed silc_net_check_host_by_sock to return FALSE if the
1562 IP/DNS could not be resolved. Though, it returns the IP address
1563 now even if it could not resolve it (but returns also FALSE).
1564 Affected file lib/silcutil/silcnet.[ch].
1566 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added silc_pkcs_decode_identifier to decode the public key's
1569 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1570 Added also silc_pkcs_free_identifier. Added also new context
1571 SilcPublicKeyIdentifier.
1573 * Added -S option to the silc client. It is used to dump the
1574 contents of the specified public key file.
1576 * Changed the PKCS api to return the public key length when
1577 setting the public key.
1579 * Fixed a fatal bug in the public and private key file loading.
1580 Affected file lib/silccrypt/silcpkcs.c.
1582 * Execute the packet parsing for client with zero (0) timeout
1583 if the protocol is active. Affected file silcd/server.c.
1585 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Made the key generation options to the silcd program. Added
1588 -C option, equivalent to client's option.
1590 * Added new [ServerKeys] config section to the server. It
1591 configures the server's public and private key.
1593 * Defined generic Public Key Payload into the protocol
1594 specification to send specific type of public keys and
1597 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1598 public key or certificate.
1600 * Implemented the GETKEY command to the server and to the
1601 client library and on user interface.
1603 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Made preliminary `make install' work.
1607 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Added SilcServerRekey context into silcd/idlist.h.
1611 * Added the PFS support as defined in the specification to the
1612 SKE protocol. Affected files lib/silcske/*.c.
1614 * Added `ske_group' field to the SilcServerRekey context to hold
1615 the number of the SKE group that is used with PFS in re-key.
1616 Affected file silcd/idlist.h.
1618 * Added PFS re-key support to the server. Affected file is
1621 * Added silc_protocol_cancel to cancel execution of the next
1622 state of the protocol. Affected file is
1623 lib/silccore/silcprotocol.[ch].
1625 * Added the re-key support with and without PFS to the client
1626 library. Re-key is performed once in an hour, by default.
1628 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1629 Added silc_client_rekey_callback and silc_client_rekey_final.
1630 Affected files are lib/silcclient/protocol.[ch] and
1631 lib/silcclient/client.[ch].
1633 * Removed the `hmac_key' and `hmac_key_len' fields from the
1634 SilcClientConnection structure; not needed. Affected file is
1635 lib/silcclient/client.h.
1639 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1641 * Do not ask whether user wants to use the negotiated private key
1642 for private messages, just use it. Affected file is
1643 silc/local_command.c.
1645 * Added `send_enc_key' and `enc_key_len' fields to the
1646 SilcIDListData structure since they are needed in the re-key
1647 phase. Affected file is silcd/idlist.[ch].
1649 * Implemented the simple re-key protocol into the server.
1650 Affected files silcd/server.c and silcd/protocol.[ch]. The
1651 re-key will be performed once in an hour, by default.
1653 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1654 Added silc_server_rekey, silc_server_rekey_callback and
1655 silc_server_rekey_final.
1657 * Removed Tunneled flag from the protocol. Updated the code
1658 and the specifications.
1660 * Adde `pfs' field to the SilcIDListData to indicate whether
1661 the PFS is to be performed in the re-key. Affected file is
1664 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1667 int64 of at least the xintXX size. If void * is less that 4
1668 bytes uint32 * will be used. Defined bool as boolean.
1670 * Changed _ALL_ unsigned long and unsigned int to uint32,
1671 unsgined short to uint16 in the source tree.
1673 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1674 not handle clients that has entry->data.registered == FALSE.
1675 They are not in the network anymore. Affected file is
1678 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1680 * Implemented the sending of the SERVER_SIGNOFF notify in the
1681 server. Affected file is silcd/server.c.
1683 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1684 Added also silc_notify_payload_encode_args into the
1685 lib/silccore/silcnotify.[ch].
1687 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1688 Affected file silcd/packet_receive.c.
1690 * Implemented the SERVER_SIGNOFF notify handling in the client
1691 library. Affected file lib/silcclient/client_notify.c. Also,
1692 implemnted the printing of the SERVER_SIGNOFF info to the
1693 application. Affected file silc/client_ops.c.
1695 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1696 if the deleting was successful. Affected file silcd/idlist.[ch].
1698 * Added support for public key authentication in the connection
1699 authentication protocol in the client library. Affected file
1700 lib/silcclient/protocol.c.
1702 * Changed the server's silc_idlist_get_clients_by_* interface
1703 to support already allocated array so that new entries may be
1704 added to pre-allocated array. Affected file silcd/idlist.[ch].
1705 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1706 and command replies.
1708 * All command reply functions in the server now calls the
1709 pending command callback even if error occured. This way the
1710 error will be delivered to the client as well. Affected files
1711 silcd/command.c and silcd/command_reply.c.
1713 * Fixed INFO command to return local server's info if no server
1714 was provided. Affected file lib/silcclient/command.c.
1716 * Removed RESTART command for good. Updated the code and the
1719 * Rewrote parts of the task system. It is a bit simpler now.
1720 Removed unsued task priorities. The affected files are
1721 lib/silcutil/silctask.[ch].
1723 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Moved the USERS printing from the library to the application.
1726 Affected files lib/silcclient/command.c and silc/client_ops.c.
1728 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Added channel key re-key support. The re-key is perfomed
1733 only by the router and is done once in an hour. Added `rekey'
1734 field to the SilcChannelEntry in the server. Affected files
1735 silcd/server.c and silcd/idlist.h.
1737 * Added silc_task_unregister_by_context into the file
1738 lib/silcutil/silctask.[ch].
1740 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added SILC_UMODE_GONE mode to indicate when the client is not
1743 present in the SILC network. Added also support to the local
1744 command AWAY that will set this mode. Added support of showing
1745 "xxx is gone" in WHOIS command. The USERS command shows the
1746 gone status as well.
1748 * Fixed setting server and router operator privileges in the
1749 server's UMODE command. Affected file silcd/command.c.
1751 * Merged the SKE KE1 and KE2 payloads into one payload. The
1752 new KE payload is equivalent to the old KE2 payload.
1754 Cleaned up the SKE Start Payload parsing. It now uses the
1755 simple buffer unformatting to do the parsing. A lot faster
1758 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1759 to the SKE that is used to indicate whether both of the SKE
1760 parties should perform authentication. By default only the
1761 responder performs authentication. By setting this flag also
1762 the initiator must do authentication. By default it is unset
1763 since in normal SKE case, client to server connection, only
1764 the responder should do authentication. When doing SKE between
1765 two clients both should perform authentication. Updated the
1766 code and the protocol specs.
1768 * A little fix to IDENTIFY command in the server. Search the
1769 client first by hash not nickname. Affected file is
1772 * Fixed the silc_client_close_connection to support closing
1773 the client to client connections wihtout deleting too much
1774 data. Affected file lib/silcclient/client.c.
1776 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1777 are received if protocol used to be active but is not anymore
1778 the application would crash due to NULL pointer dereference.
1779 Affected files silcd/server.c and lib/silcclient/client.c.
1781 * Added `hash' field to the SilcClientConnection to include
1782 the hash function negotiated in the SKE protocol.
1784 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1785 to set the channel founder authentication data. A client can
1786 claim the founder rights later by providing the authentication
1787 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1788 This way the channel founder can regain the channel founder
1789 privileges even it is left the channel. This works only on
1790 local server and the client must be connected to the same
1791 server to be able to regain the founder rights. Updated the
1792 protocol specs accordingly.
1794 Added support to the CMODE command in the client to set the
1795 founder auth data. Read the README to see how to set it.
1797 Added support to the CUMODE command to claim the founder
1798 rights. Read the README to see how to do it.
1800 Added support for the founder authentication to the Channel
1801 Entry in the server. Affected file silcd/idlist.h.
1803 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1804 server's CMODE command. Affected file silcd/command.c.
1806 * Added the following new functions into lib/silccore/silcauth.[ch]:
1807 silc_auth_get_method and silc_auth_get_data.
1809 * The server now saves the remote hosts public key to the
1810 SilcIDListData pointer. Affected file silcd/protocol.c.
1812 * The normal server now does not remove the channel entry from
1813 the cache if the founder authentication data is set. It used
1814 to remove it if the founder was the last one on the channel on
1815 the server and left the channel. The auth data is saved and
1816 if the channel is re-joined later the old entry is used with
1817 the old auth data. Affected files silcd/command_reply.c and
1820 * Removed the `pkcs' field from the SilcIDListData structure
1821 in the server; it is not used. Affected file silcd/idlist.h.
1823 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Fixed packet processing on slow links. Partial packets were
1826 never re-processed because the incoming data buffer was cleared
1827 by the application. Application must not directly clear the
1828 sock->inbuf, the packet processing routines handle it. Fixed
1829 this in client library and in server.
1831 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Fixed the WHOIS and IDENTIFY send reply function to really
1834 check whether to send list or just one entry. Affected file
1837 * Cleaned up the LEAVE command's channel key distribution. The
1838 affected file silcd/command.c.
1840 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1841 can enforce the channel mode as well. In that case the ID
1842 includes the ID of the server. The code now enforces the
1843 mode change if the router have different mode than the server.
1845 * The notify client operation with CMODE_CHANGE notify can now
1846 return NULL client_entry pointer if the CMODE was not changed
1847 by client. Application must check for this.
1849 * Added <Server ID> argument to INFO command to support server
1850 info fetching by Server ID.
1852 * Added silc_server_announce_get_channel_users to get assembled
1853 packets of channel users of the specified channel. Affected
1854 file silcd/server.[ch].
1856 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1857 was freed underneath the ID Cache.
1859 * Re-announce clients when the server received CHANNEL_CHANGE
1860 notify from the router. Affected file silcd/packet_send.c.
1862 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1864 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1865 crashed since it did not handle the fact that there is no cipher
1866 called "3" and didn't check the error condition. Now fixed.
1868 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1869 flag. It can be used to send message requests.
1871 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Implemented the RESTART command in the client.
1875 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1876 notice type messages. Added notice printing to the user
1879 * The channel keys are not re-generated if the channel's mode
1880 is PRIVKEY, ie private key on the channel exists. Affected
1881 files silcd/server.c and silcd/command.c.
1883 * Fixed a little bug in channel message delivery when channel
1884 private keys are set in the server. Affected file is
1885 silcd/packet_send.c.
1887 * Changed the setting on channel->on_channel = TRUE from the
1888 silc_client_save_channel_key to the JOIN command reply. The
1889 key payload is not received if the private channel key is set.
1890 Affected file lib/silcclient/command_reply.c and the
1891 lib/silcclient/client_channel.c.
1893 * When the CMODE_CHANGE notify is sent and the channel private
1894 key mode is removed the channel key must be re-generated in
1895 other cells as well. Added this support for the router in the
1896 silcd/packet_receive.c.
1898 * Added new local command NOTICE to send notice message on
1899 channel. Affected file silc/local_command.[ch].
1901 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Added new local command ME to the client. It is used to send
1904 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1905 some action. Affected file silc/local_command.[ch].
1907 * Changed channel_message and private_message client operations
1908 to deliver the message flags to the application. Added also
1909 the `flags' arguments to the silc_client_send_channel_message
1910 and silc_client_send_private_message functions. Affected file
1913 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Redefined the Private Message Payload to support private message
1916 keys and to support the new private message flags. Updated
1917 the protocol specs. Flags makes it possible to have for example
1918 CTCP style messages.
1920 * Added new type SilcPrivateMessagePayload and defined an API
1921 for it in the lib/silcclient/silcprivate.[ch].
1923 * Tested private message private keys successfully. Tested the
1924 private message key set, unset and list commands with the new
1927 * Redefined the Channel Message Payload to include the channel
1928 message flags (equal with private message flags) to support
1929 for example CTCP style messages.
1931 * Defined some of the message (for channel and private message)
1932 flags. Updated the protocol specs and added the flags to the
1933 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1935 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Added SilcKeyAgreementStatus type to the key agreement routines
1938 to indicate the current status and error if one occured.
1939 The status types are defined in the lib/silcclient/silcapi.h.
1941 * Added new local command KEY that is used to set and unset private
1942 keys for channels, set and unset private keys for private messages
1943 with remote clients and to send key agreement requests and
1944 negotiate the key agreement protocol with remote client. The
1945 key agreement is supported only to negotiate private message keys,
1946 it currently cannot be used to negotiate private keys for channels,
1947 as it is not convenient for that purpose.
1949 * Fixed a minor pending callback setting bug in the function
1950 silc_client_get_client_by_id_resolve, now the function works.
1951 Affected file lib/silcclient/idlist.c.
1953 * Added function silc_net_get_local_port to get local bound
1954 port by socket. Added to lib/silcutil/silcnet.[ch].
1956 * Added `sockets' and `sockets_count' fields to the SilcClient
1957 object. They hold the sockets of the listenning sockets in
1958 the client. Listenning sockets may be for example the key
1959 agreement server. Affected file lib/silcclient/client.[ch].
1960 Added functions the silc_client_add_socket and the
1961 silc_client_del_socket. They are exported to the application
1964 * Added ~./silc/clientkeys to support other client's public keys.
1966 * Renamed verify_server_key client operation to verify_public_key
1967 and added one argument to indicate the type of the connection
1968 (server, client etc.).
1970 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Added silc_server_connection_auth_request to handle the
1973 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1974 silcd/packet_receive.[ch].
1976 * Added silc_server_send_connection_auth_request into the
1977 silcd/packet_send.c to send the connection auth request packet.
1979 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1982 * Fixed the public key authentication in responder side in the
1983 server. The `auth_data' pointer includes the SilcPublicKey
1984 not the path to the public key. Affected file silcd/protocol.c.
1986 * Implemented the public key authentication in the initiator side
1987 in the server. Affected file silcd/protocol.c.
1989 * Removed the [RedirectClient] config section from the server
1990 configuration. Is not needed and I don't want to implement it.
1992 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Cleaned up the CMODE command in the server. It now works
1995 correctly and supports all the modes defined in the protocol.
1996 Affected file is silcd/command.c.
1998 * Added `hmac_name' field to the SilcChannelEntry in the server
1999 to hold the default HMAC of the channel. It can be set when
2000 creating the channel (with JOIN command). Affected files
2003 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2004 type to indicate the change of the current cipher and hmac
2005 on the channel. Client can safely ignore the <cipher> argument
2006 (if it chooses to do so) since the CHANNEL_KEY packet will
2007 force the channel key change anyway. The <hmac> argument is
2008 important since the client is responsible of setting the new
2009 HMAC and the hmac key into use.
2011 * Fixed the CMODE command in the client library as well.
2013 * Tested CMODE command in router environment successfully.
2015 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Show the version of the remote client (or server) when connecting
2018 to the server. It is logged to the log file. Affected file
2019 is silcd/protocol.c.
2021 * Fixed the KILLED notify handling in the client library. The
2022 client must be removed from all channels when receiving the
2025 Also, do not remove the client entry when giving the KILL
2026 command but when the KILLED notify is received.
2028 * Removed silc_idlist_find_client_by_nickname from the server.
2029 Not needed anymore. Affected files silcd/idlist.[ch].
2031 * Implemented the CHANNEL_CHANGE notify type handling to the
2032 server. Affected file silcd/server.c.
2036 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Added silc_server_send_notify_invite to send the INVITE
2039 notify between routers.
2041 * Implemented the INVITE command correctly to the server.
2043 * Implemented the INVITE notify type handling in the server.
2045 * Implemented the INVITE command to the client library and on the
2048 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Added function silc_server_get_client_resolve to find the
2051 client entry by ID from all ID lists and then resolve it
2052 (using WHOIS) if it cannot be found. Affected file is
2055 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Implemented the BAN command to the client library.
2059 * The JOIN command in the server now checks the invite list
2062 * Changed the silc_command_reply_payload_encode_va and the
2063 silc_command_payload_encode_va to support that if argument is
2064 NULL it ignores and checks the next argument. Affected file
2065 lib/silccore/silccommand.c.
2067 * Added silc_server_send_notify_ban to send the BAN notify
2068 type between routers.
2070 * Chaned the silc_notify_payload_encode to support that if
2071 argument is NULL it ignores and checks the next argument.
2072 Affected file lib/silccore/silcnotify.c.
2074 * Tested ban lists in router environment successfully.
2076 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * Implemented BAN command to the server, in silcd/command.[ch].
2080 * Removed the BAN and INVITE_LIST modes from the CMODE command
2083 * Added function silc_string_match to regex match two strings.
2084 Affected files lib/silcutil/silcutil.[ch].
2086 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Redefined parts of the SilcChannelEntry in the server to support
2089 the new ban and invite lists.
2091 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Redefined the INVITE command. The same command can be used to
2094 invite individuals to the channel but also to manage the invite
2095 list of the channel (to add to and remove from the invite list).
2096 Updated the protocol specs.
2098 * Added new command SILC_COMMAND_BAN that can be used to manage
2099 the ban list of the channel. Updated the protocol specs.
2101 * Removed the channel modes: the SILC_CMODE_BAN and the
2102 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2103 in the CMODE command. The equivalent features are now available
2104 using INVITE and BAN commands. Updated the protocol specs.
2106 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2107 in the network about change in the current ban list. The notify
2108 type is not used by the client.
2110 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2111 support the invite lists.
2113 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Added new function silc_string_regexify that converts string
2116 including wildcard characters into regex string that can
2117 be used by the GNU regex library. Added into the file
2118 lib/silcutil/silcutil.[ch].
2120 Added silc_string_regex_combine to combine to regex strings
2121 into one so that they can be used as one regex string by
2122 the GNU regex library. Added into the file
2123 lib/silcutil/silcutil.[ch].
2125 Added silc_string_regex_match to match two strings. It returns
2126 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2128 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Imported GNU regex to the soruce tree into lib/contrib.
2131 Fixed some compiler warning from the regex.c.
2133 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Fixed MOTD command in the server to work in router environment.
2137 * Fixed the MOTD command in the client library to support
2138 the server argument in the command.
2140 * Added `nickname_len' argument to the silc_idlist_add_client
2141 in the server, as the `nickname' argument may be binary data
2144 * Added silc_idlist_get_channels to return all channels from
2147 * Implemented LIST command to the server. Affected file is
2150 * Implemented the LIST command to the client library and on the
2153 * Added [<user count>] argument to the LIST command reply.
2154 With private channels the user count is not shown.
2156 * Updated TODO and README.
2158 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * The client entry's data.registered must be TRUE even with
2161 global client entry on global client list. The data.registered
2162 is used to check whether the client is anymore in the network,
2163 for example with WHOWAS command so it must be valid.
2165 * Fixed the WHOWAS command in the server. It now actually works
2166 in router environment. Added function into silcd/command_reply.c
2167 silc_server_command_reply_whowas_save.
2169 * Added silc_idlist_purge function to the silcd/idlist.c
2170 to periodically purge the ID Cache.
2172 * Fixed INFO command in the server. It works now in router
2173 environment. Added <server name> argument to the INFO command
2174 reply. Updated the protocol specs.
2176 * Fixed minor bug in silc_idcache_purge to not purge if the
2177 expire value is zero.
2179 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2180 they were buggy because of the WHOWAS information.
2182 * Fixed local command MSG to handle the async resolving of
2183 the remote client properly. It used to fail the first MSG.
2184 Affected file silc/local_command.c.
2186 * Added `data_len' field to SilcIDCache context.
2188 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Update TODO. Todo in commands in the server.
2192 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2195 used by routers as broadcast packet to inform other routers
2196 about the changed user mode.
2198 Implemented the notify handling in the server. Affected file is
2199 silcd/packet_receive.c. Added the function
2200 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2202 * Added new generic Channel Payload and deprecated the New Channel
2203 Payload. The New Channel Payload is now the generic Channel
2206 * Added new argument `mode' to the silc_server_send_new_channel
2207 as it is required in the Channel Payload now.
2209 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2210 and created a new and real SilChannelPayload to represent the
2211 new generic Channel Payload. Implemented the encode/decode
2212 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2214 * Added silc_server_get_client_channel_list to return the list
2215 of channels the client has joined for WHOIS command reply.
2216 Affected file silcd/server.[ch].
2218 * Implemented the channel list sending in the WHOIS command reply
2219 in server and in the client.
2221 Implemented the channel list displaying on the user interface
2222 as well. Affected file silc/client_ops.c.
2224 * Added silc_channel_payload_parse_list to parse list of Channel
2225 Payloads. It returns SilcDList list of SilcChannelPayloads.
2226 Client for example can use this function to parse the list of
2227 channels it receives in the WHOIS command reply. The caller
2228 must free the list by calling silc_channel_payload_list_free.
2229 Affected files lib/silccore/silcchannel.[ch].
2231 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Added one new argument <user mode> to the WHOIS command reply
2234 to return the mode of the user in SILC. Updated the protocol
2237 Implemented it to the server and client.
2239 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Fixed the mode printing on the user interface on joining.
2242 Affected file silc/client_ops.c.
2244 * Implemented the UMODE command and user modes in general to the
2245 client library and to the user interface.
2247 * Implemented the UMODE command to the server.
2249 * The server now sends UNKNOWN_COMMAND error status if client sends
2250 unknown command. Affected file silcd/command.c.
2252 * All server commands now handle the command identifier the right
2253 way when sending the command reply to the client. The client can
2254 use to identify the command replies with the identifier.
2256 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2258 * Added silc_server_get_client_route to resolve the route to
2259 the client indicated by the client ID. Affected file is
2262 * Added silc_server_relay_packet as general function to relay
2263 packet to arbitrary destination. This deprecates functions
2264 like _send_private_message_key, _relay_notify etc. Affected
2265 file is silcd/packet_send.[ch].
2267 Removed silc_server_send_key_agreement,
2268 silc_server_send_private_message_key and
2269 silc_server_packet_relay_notify functions from the file
2270 silcd/packet_send.[ch].
2274 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2275 server. Affected file silcd/packet_receive.[ch].
2277 * Implemented the KILL command to the client. Implemented the
2278 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2279 Affected files lib/silcclient/command[_reply].c and
2280 lib/silcclient/client_notify.c. Implemented the KILL notify
2281 printing in the user inteface.
2283 * Fixed a lot silc_parse_nick memory leaks from the client
2284 library in the file lib/silcclient/command.c.
2286 * Changed the silc_server_send_notify_on_channels's `sender'
2287 argument from SilcSocketConnection to SilcClientEntry to
2288 check the sender as entry and not as connection object and not
2289 to send to the client provided as argument. The affected file
2290 is silcd/packet_send.[ch].
2292 * The notify packets that are destined directly to the client used
2293 to not to be processed by the server. Now changed that and the
2294 server processes all notify packets. After relaying the packet
2295 to the client the notify packet is processed in the server.
2297 * The silc_server_free_client_data now checks whether there is
2298 pending outgoing traffic for the client and purges the data to
2299 the network before removing the client entry.
2301 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2304 an client is killed from the SILC Network. Updated the protocol
2307 Added new function silc_server_send_notify_killed to the
2308 silcd/packet_send.[ch].
2310 * Added function silc_server_packet_relay_notify to relay notify
2311 packets that are destined directly to a client. In this case
2312 the server does not process the notify packets but merely relays
2313 it to the client. Affected file silcd/packet_send.[ch].
2315 Added also silc_server_packet_process_relay_notify to check
2316 whereto relay the notify. Affected file is
2317 silcd/packet_receive.[ch].
2319 * Implemented the KILL command to the server.
2323 * Added the backup schema desgined last fall to the protocol
2324 specs for everyone to see. The specification is in the
2325 *-spec-xx.txt draft and the packet type definitions for the
2326 backup routers is in *-pp-xx.txt draft. Thusly, added also
2327 new packet type SILC_PACKET_CELL_ROUTERS.
2329 * A big security problem in the implementation discovered. The
2330 signoff of an client did not cause new channel key generation
2331 which it of course should've done. The channel keys must be
2332 always re-generated when client leaves (or signoffs) the channel.
2333 The silc_server_remove_from_channels funtion now handles
2334 the channel key re-generation.
2336 * Added `sender' argument to the silc_server_send_notify_on_channels
2337 to not to send the client provided as argument. Affected file
2338 silcd/packet_send.[ch].
2340 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Implemented OPER and SILCOPER commands into the server and
2345 * Added silc_auth_verify and silc_auth_verify_data to verify
2346 the authentication directly from the authentication payload.
2347 It supports verifying both passphrase and public key based
2348 authentication. Affected file lib/silccore/silcauth.[ch].
2350 * Added `hash' field to the SilcIDListData structure. It is the
2351 hash negotiated in the SKE protocol. Affected file is
2354 * Slight redesigning of the SilcAuthPayload handling routines.
2355 Do not send SilcPKCS but SilcPublicKey as argument.
2357 * Implemented the public key authentication support to the
2358 serverconfig. The public key is loaded from the provided path
2359 and saved as authentication data to void * pointer. Thus,
2360 changed the unsigned char *auth_data to void *auth_data;
2362 * Fixed SHUTDOWN command to send the reply before the server
2363 is shutdown. :) Affected file silcd/command.c.
2365 * Fixed fatal bug in CONNECT command. The hostname was invalid
2366 memory and server crashed. Affected file silcd/command.c.
2368 * Fixed fatal bug in CLOSE command. The server_entry became
2369 invalid but was referenced later in the command. Affected file
2372 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Fixed fatal bug in failure packet handling. Server ignored
2375 the failure and thus crashed when it came.
2379 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2382 that the command may be executed only once in (about) 2 seconds.
2383 The old SILC_CF_LAG flag is same but allows command bursts up
2384 to five before limiting.
2386 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2387 server code. Various commands now includes the CF_LAG_STRICT
2388 flag to disallow any kind of miss-use of the command.
2390 * Fixed the silc_buffer_unformat to not to allocate any data
2391 if the length of the data is zero. It used to allocate the
2392 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2394 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Changed the format of AdminConnection configuration section
2397 in the server. Added username of the admin to the format.
2398 Affected files silcd/serverconfig.[ch].
2400 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2401 to return admin configuration data by host, username and/or
2404 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Implemented WHOWAS command to the server. Added the functions:
2408 silc_server_command_whowas_parse,
2409 silc_server_command_whowas_send_reply,
2410 silc_server_command_whowas_from_client and
2411 silc_server_command_whowas_from_server
2413 * Added <Client ID> argument to the WHOWAS command reply. Updated
2414 the protocol specs accordingly.
2416 * Implemented WHOWAS command and command_reply to the client
2419 Implemented the WHOWAS printing on the user interface.
2421 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Added new argument to the WHOWAS command reply, the real name.
2424 It is an optional argument. Updated the protocol specs.
2426 * Added SilcIDCacheDestructor callback that is registered when
2427 the SilcIDCache is allocated. The callback is called when
2428 an cache entry in the ID Cache expires, or is purged from the
2429 cache. Added into lib/silccore/idcache.[ch].
2431 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2432 to destruct the client entries when the cache entry expires.
2433 Other ID Cache's in server and in the client library ignores
2436 * If the ID Cache entry's `expire' field is zero then the entry
2437 never expires. Added boolean `expire' argument to the
2438 silc_idcache_add function in the lib/silccore/idcache.[ch].
2439 If it is TRUE the default expiry value is used.
2441 * Added silc_server_free_client_data_timeout that is registered
2442 when client disconnects. By default for 5 minutes we preserve
2443 the client entry for history - for WHOWAS command.
2445 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * Added support to the server to enforce that commands are not
2448 executed more than once in 2 seconds. If server receives
2449 commands from client more frequently, timeout is registered
2450 to process the commands. Affected file silcd/command.c.
2451 Added new function silc_server_command_process_timeout.
2453 * Changed NICK_NOTIFY handling in client library to check that
2454 if the client's nickname was changed, so there is no need to
2455 resolve anything from the server.
2457 * Removed error printing from the WHOIS and IDENTIFY commands.
2458 If error occurs then it is ignored silently in the client library.
2459 The application, however, may map the received error to
2460 human readable error string. The application currently maps
2461 the NO_SUCH_NICKNAME error to string.
2463 * Made the command status message public to the application. Moved
2464 them from lib/silcclient/command_reply.c to
2465 lib/silcclient/command_reply.h. The application can map the
2466 received command status to the string with the
2467 silc_client_command_status_message function.
2469 * Added check to the server to check that client's ID is same
2470 as the Source ID in the packet the client sent. They must
2473 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added dist-bzip hook to the Makefile.am to make bzip2
2476 compressed distributions.
2478 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Server now enforces the maximum length for the nickname and
2481 the channel as protocol specification dictates. 128 bytes for
2482 nickname and 256 bytes for channel name.
2484 * Moved the WHOIS printing to the application. The client libary
2485 does not print out the WHOIS information anymore, the application
2486 must do it. Renamed silc_client_command_reply_whois_print to
2487 the silc_client_command_reply_whois_save.
2489 The client's idle time is also sent to the application now, and
2490 the idle is shown on screen.
2492 * Added silc_client_command_reply_identify_save to save the
2493 received IDENTIFY entries.
2495 * Do not check for channel private keys in message sending and
2496 reception if the channel does not have the PRIVKEY mode set.
2497 Affected file lib/silclient/client_channel.c.
2499 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2502 just surfaced after chaning the JOIN procedure.
2504 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Added silc_client_get_clients_by_list to get client entries
2507 from Client ID list, that is returned for example by JOIN
2508 and USERS command replies. The application should use this
2509 function for example when JOIN command reply is received to
2510 resolve the clients already on the channel (library does not
2511 do that anymore as USERS command reply is not used in the JOIN
2512 procedure anymore). Affected files lib/silcclient/silcapi.h and
2513 lib/silcclient/idlist.c.
2515 * JOIN command reply and USERS command reply returns now SilcBuffer
2516 pointers instead of unsigned char pointers when returning
2517 the client list and mode list.
2519 * Added <Client ID> argument to the JOIN command reply, mainly
2520 for the server to identify for which client the command was
2521 originally sent. Updated protocol specs accordingly.
2523 * Added SilcDlist private_key pointer to the SilcChannelEntry
2524 in the client to support the channel private keys. Affected
2525 file is lib/silcclient/idlist.h.
2527 * Added SilcChannelPrivateKey argument to the function
2528 silc_client_send_channel_message so that application can choose
2529 to use specific private ke if it wants to. If it is not provided,
2530 the normal channel key is used, unless private keys are set.
2531 In this case the first (key that was added first) is used
2532 as the encryption key.
2534 * Implemented the support for channel private key handling.
2535 Implemented the following functions:
2537 silc_client_add_channel_private_key,
2538 silc_client_del_channel_private_keys,
2539 silc_client_del_channel_private_key,
2540 silc_client_list_channel_private_keys and
2541 silc_client_free_channel_private_keys
2543 Affected file lib/silcclient/client_channel.c.
2545 * Added the support for the private keys in the channel message
2546 sending and encryption and in the message reception and
2547 decryption. Affected funtions are
2548 silc_client_send_channel_message and silc_client_channel_message.
2550 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added SKE's key verify callback to the client library's
2553 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2555 * Removed the statement that server (or router) must send USERS
2556 command reply when joining to the channel so that the client
2557 knows who are on the channel. Instead, the client list and
2558 client's mode list is now sent in the JOIN command reply to the
2559 client who joined channel. This is better solution.
2561 * Added function silc_server_get_users_on_channel and function
2562 silc_server_save_users_on_channel to the silcd/server.[ch].
2564 * Removed function silc_server_command_send_users from the
2567 * Do not show topic on the client library anymore. The topic is
2568 sent in the command reply notify to the application and the
2569 application must show the topic now.
2571 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Added client searching by nickname hash into the IDENTIFY and
2574 WHOIS commands in the server as they were clearly missing from
2575 them. Affected file is silcd/command.c.
2577 * Fixed a bug in private message receiving in the client library.
2578 The remote ID was freed and it wasn't supposed, now it is
2581 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Minor fix to the channel payload; allocate the data area, as it
2584 needs to be of specific length.
2586 * If the key agreement port is zero then the operating
2587 system will define the bound port. Affected files are
2588 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2590 * Added new function silc_channel_payload_decrypt into the file
2591 lib/silccore/silcchannel.[ch].
2593 * Moved the channel message etc, check from silc_packet_decrypt
2594 to applications. The library calls now a generic
2595 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2596 when the packet is either normal or special. This was done to
2597 allow more wide range of checking that was not allowed when
2598 the code was in library. Now applications can do virtually any
2599 checks to the packet and return to the library the decision how
2600 the packet should be processed. Affected files are
2601 lib/silccore/silcpacket.[ch].
2603 Added silc_server_packet_decrypt_check to the server and
2604 silc_client_packet_decrypt_check to the client library.
2606 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2607 to send with specified source and destination information.
2609 * Channel message delivery between routers was broken after the
2610 channel key distribution was fixed earlier. The channel key
2611 was used be to distributed to other routers as well which is not
2612 allowed by the protocol. Now this is fixed and channel keys
2613 really are cell specific and the channel message delivery between
2614 routers comply with the protocol specification.
2616 * Fixed various commands in server to check also the global list
2617 for the channel entry and not just the local list. The affected
2618 file silcd/command.c.
2620 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Added assert()s to buffer formatting and unformatting routines
2623 to assert (if --enable-debug) when error occurs. Affected
2624 file: lib/silcutil/silcbuffmt.c.
2626 * Changed to auto-reconnect to check whether the remote host is
2627 router and register the re-connect timeout if it is. It used
2628 to check that whether we are normal server, but router must do
2629 auto-reconnect with another router as well. Affected file
2632 * Removed the [<key len>] option from CMODE command as the cipher
2633 name decides the key length, nowadays. See the defined ciphers
2634 from the protocol specification.
2636 * Added [<hmac>] option to the CMODE command to define the HMAC
2637 for the channel. Added SILC_CMODE_HMAC channel mode.
2639 * Added [<hmac>] option for the JOIN command so that user can
2640 select which HMAC is used to compute the MACs of the channel
2643 * Added Hmac field to the Channel Message Payload. The integrity
2644 of plaintext channel messages are now protected by computing
2645 MAC of the message and attaching the MAC to the payload. The
2646 MAC is encrypted. Now, it is clear that this causes some
2647 overhead to the size of the packet but rationale for this is that
2648 now the receiver can verify whether the channel message decrypted
2649 correctly and also when private keys are set for the channel the
2650 receiver can decrypt the packet with several keys and check from
2651 the MAC which key decrypted the message correctly.
2653 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2654 lib/silccrypt/silccipher.[ch].
2656 * Added silc_hash_len to return the digest length into the
2657 lib/silcrypt/silchash.[ch].
2659 * Rewrote parts of Silc Channel Payload interface in the
2660 lib/silccore/silcchannel.[ch]. The encode function now also
2661 encrypts the packet and parse function decrypts it.
2663 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2665 * Fixed a minor formatting bug in the SKE's key material processing.
2666 It actually might have processed the keys wrong way resulting
2669 * Redefined the mandatory HMAC algorithms and added new algorithms.
2670 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2671 and hmac-md5 truncated to 96 bits. The mandatory is now
2672 hmac-sha1-96. Rest are optional (including the one that used
2673 to be mandatory). Rationale for this is that the truncated HMAC
2674 length is sufficient from security point of view and can actually
2675 make the attack against the HMAC harder. Also, the truncated
2676 HMAC causes less overhead to the packets. See the RFC2104 for
2679 * Added new [hmac] configuration section. The SKE used to use
2680 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2681 is of course wrong. The official names that must be proposed in
2682 the SKE are the ones defined in the protocol specification
2683 (hmac-sha1-96 for example). The user can configure any hmac
2684 using any hash function configured in the [hash] section. At
2685 least, the mandatory must be configured.
2687 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2689 * Added HMAC list to the SKE proposal list. It has now both
2690 hash algorithm list and HMAC list. This makes the protocol
2691 incompatible with previous versions. The SKE now seems to work
2692 the way it is supposed to work, for the first time actually.
2694 * Defined plain Hash algorithms to the protocol specification.
2697 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Implemented support for key agreement packets into the server.
2700 Added functions silc_server_key_agreement and
2701 silc_server_send_key_agreement. Other than these functions,
2702 server has nothing to do with this packet.
2704 * Added support for private message key packets into the server.
2705 Added functions silc_server_private_message_key and
2706 silc_server_send_private_message_key.
2710 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2711 called in the protocol's final callback instead in the END
2712 protocol state. This makes a little more sense and in the same
2713 time in client we can use the same protocol routines for normal
2714 key exchange and to key agreement packet handling as well.
2716 * Added to both client's and server's KE protocol context the
2717 SilcSKEKeyMaterial pointer to save the key material. We will
2718 bring the key material to the protocol's final callback by doing
2719 this. The final callback must free the key material.
2721 * Added SKE's packet_send callback into client's KE protocol
2722 context so that the caller can choose what packet sending function
2723 is used. This way we can use different packet sending when
2724 doing normal SKE when doing key agreement packet handling (in
2725 the key agreement packet handling we do not want to encrypt
2728 * Implemented the responder side of the key agreement routines
2729 in the client. The client can now bind to specified port and
2730 accept incoming key negotiation. The key material is passed
2731 to the application after the protocol is over.
2733 * Implemented the processing of incoming Key Agreement packet
2734 in the client. Added function silc_client_key_agreement to
2737 * Implemented the intiator side of the key agreement routines
2738 in the client. The client can now initiate key agreement with
2739 another remote client. The key material is passed to the
2740 application after the protocol is over.
2742 * Created client_keyagr.c to include all the key agreement
2745 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2746 SILC_TASK_CALLBACK except that it is not static.
2748 * Created client_notify.c and moved the Notify packet handling
2749 from the client.[ch] into that file.
2751 * Created client_prvmsg.c and moved all private message and
2752 private message key routines from the client.[ch] into that file.
2754 * Create client_channel.c and moved all channel message and
2755 channel private key routines from the client.[ch] into that file.
2757 * Changed silc_client_get_client_by_id_resolve to resolve with
2758 WHOIS command instead of IDENTIFY command, in the file
2759 lib/silclient/idlist.c.
2761 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Implemented the SKE's responder side to the Client library.
2765 * When FAILURE is received to the protocol do not trust it
2766 blindly. Register a timeout to wait whether the remote closes
2767 the connection as it should do it, only after that process the
2768 actual failure. This was changed to both client and server.
2770 * Added client_internal.h to include some of the structures
2771 there instead of client.h in lib/silcclient/.
2773 * Added function silc_task_unregister_by_callback to unregister
2774 timeouts by the callback function.
2776 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Some "Incomplete WHOIS info" errors has been appearing on the
2779 log files. Took away the entry->userinfo check from WHOIS
2780 reply sending. The entry->userinfo is now " " if client did not
2781 provide one. I thought this was fixed earlier but something
2782 is wrong still. Let's see if the error still appears.
2784 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Fixed a minor bug in the login when the channel key is
2787 re-generated in the server. It used to generate the key in
2788 wrong order and thus caused problems in the channel traffic.
2790 * Fixed a minor bug in channel key distsribution after
2791 KICK command. The key was not sent to the router even though
2794 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Added silc_ske_process_key_material_data as generic routine
2797 to process any key material as the SILC protocol dictates. The
2798 function is used by the actual SKE library but can be used by
2799 applications as well. This relates to the private message keys
2800 and the channel private keys since they must be processed the
2801 same way the normal SILC session keys. The protocol dictates
2802 this. Affected files: lib/silcske/silcske.[ch].
2804 Added also silc_ske_free_key_material to free the
2805 SilcSKEKeyMaterial structure.
2807 * Defined silc_cipher_set_key function to set the key for
2808 cipher without using the object's method function. The affected
2809 files: lib/silccrypt/silccipher.[ch].
2811 * Implemented silc silc_client_add_private_message_key,
2812 silc_client_add_private_message_key_ske,
2813 silc_client_del_private_message_key,
2814 silc_client_list_private_message_keys and
2815 silc_client_free_private_message_keys functions in the
2818 Added functions silc_client_send_private_message_key to send
2819 the Private Message Key payload and silc_client_private_message_key
2820 to handle incoming Private Message Key payload.
2822 * Added Cipher field to the Private Message Key payload to set
2823 the cipher to be used. If ignored, the default cipher defined
2824 in the SILC protocol (aes-256-cbc) is used.
2826 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Removed lib/silcclient/ops.h file.
2830 Redefined parts of the SILC Client Library API. Created new
2831 file silcapi.h that deprecates the ops.h file and defines the
2832 published Client Library API. Defined also private message key
2833 API and channel private key API into the file.
2835 This is the file that the application must include from the
2836 SILC Client Library. Other files need not be included by
2837 the application anymore.
2839 * Added new key_agreement client operation callback and also
2840 defined the Key Agreement library API for the application.
2842 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2845 is used by clients to request key negotiation between another
2846 client in the SILC network. If the negotiation is started it
2847 is performed using the SKE protocol. The result of the
2848 negotiation, the secret key material, can be used for example
2849 as private message key.
2851 Implemented the Key Agreement payload into the files
2852 lib/silccore/silauth.[ch].
2854 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Redefined ciphers for the SILC protocol. Added some new ciphers
2857 and defined the key lengths for the algorithms. Changed the
2858 code accordingly. The default key length is now 256 bits.
2860 * Fixed SKE key distribution function silc_ske_process_key_material
2861 when the key length is more than 128 bits. The default key
2862 length in SILC is now 256 bits.
2864 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2865 to indicate unsupported algorithm.
2867 * Renamed rijndael.c to aes.c and all functions as well.
2869 * Fixed a long standing channel key setting bug in client library.
2870 Weird that it has never surfaced before.
2872 * Fixed bug in channel deletion. If the entire channel is removed
2873 then it must also delete the references of the channel entry
2874 from the client's channel list as the client's channel entry and
2875 the channel's client entry share same memory.
2877 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Implemented CONNECT and SHUTDOWN commands in the client.
2881 * Implemented CLOSE command to the client.
2883 * Added the function silc_idlist_find_server_by_name into the
2884 files silcd/idlist.[ch].
2886 Added the function silc_idlist_find_server_by_conn into the
2887 files silcd/idlist.[ch].
2889 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * DIE command was renamed to SHUTDOWN. Updated the both code
2894 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2895 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2897 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2900 * Added function silc_server_create_connection function to create
2901 connection to remote router. My server implementation actually
2902 does not allow router to connect to normal server (it expects
2903 that normal server always initiates the connection to the router)
2904 so the CONNECT command is only good for connecting to another
2907 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2910 or some other client was kicked from the channel.
2912 Implemented the handling of the notify type to both client
2915 Implemented silc_server_send_notify_kicked to send the KICKED
2916 notify. It is used to send it to the server's primary router.
2918 * Implemented the KICK command into server and client.
2920 * Added `query' argument to the silc_idlist_get_client function
2921 to indicate whether to query the client from server or not if
2924 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2925 to indicate that the client is not channel founder.
2929 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Removed the rng context from SilcPacketContext structure and
2932 changed that the packet routine uses the Global RNG API.
2934 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Added support for quit message that client can "leave" on the
2937 channel when it quits the SILC. It is ditributed inside the
2938 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2940 Added silc_server_free_client_data that will take the
2941 signoff message as argument.
2943 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2945 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Updated parts of the protocol specification to keep it up
2950 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2953 payloads in one packet.
2955 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2956 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2957 use now the new List flag.
2959 * Also deprecated the following packet types: REPLACE_ID,
2960 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2962 * Added list support for Notify packet in server.
2964 * Added silc_server_send_notify_channel_change to send the
2965 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2966 the silc_server_send_replace_id.
2968 * Added silc_server_send_notify_nick_change to send the
2969 NICK_CHANGE notify type. Deprecates the function
2970 silc_server_send_replace_id.
2972 * Added silc_server_send_notify_join to send the JOIN notify type.
2973 Deprecates the function silc_server_send_new_channel_user.
2975 * Added silc_server_send_notify_leave to send LEAVE notify type.
2976 Deprecates the function silc_server_send_remove_channel_user.
2978 * Added silc_server_send_notify_cmode and
2979 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2980 types. Deprecates the silc_server_send_set_mode function.
2982 * Added SERVER_SIGNOFF notify type to indicate that server has
2983 quit. This means that all clients on the channel from that
2984 server will drop. This can be also used when netsplit happens.
2986 Deprecated REMOVE_ID packet type since it is not needed anymore
2989 Added silc_server_send_notify_server_signoff to send the
2990 SERVER_SIGNOFF notify type. Deprecates the function
2991 silc_server_send_remove_id.
2993 Added also silc_server_send_notify_signoff to send the
2994 SIGNOFF notify type.
2996 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2997 SILC protocol from this day on. Changed the protocol
2998 specification as well.
3000 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3001 notify type. It is used between routers to notify about
3002 topic changes on a channel.
3004 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3007 * Partly updated the protocol specification to comply with the
3008 changes now made. It is still though a bit outdated.
3010 * The JOIN notify type now takes one extra argument <Channel ID>.
3011 The packet used to be destined to the channel but now the
3012 JOIN type may be sent as list thus it is impossible to
3013 destine it to any specific channel. By adding this argument
3014 it is again possible.
3016 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Added CREDITS file. The CHANGES and CREDITS file will appear
3019 in the distribution as well.
3021 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3024 types in the server's silcd/packet_receive.c.
3026 * Implemented CMODE and CUMODE to work in router environment.
3028 * Fixed minor encoding and decoding buglet from the
3029 lib/silccore/silcmode.c.
3031 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3034 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3036 * Changed all SilcConfigServer* and silc_config_server* to
3037 SilcServerConfig* and silc_server_config*, respectively.
3040 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Associated the ID (client or server ID) to the Authentication
3043 Payload to avoid any possibility of forging. Updated the
3044 protocol specification and the code accordingly.
3046 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * The RSA key length is now save to the RsaKey context in the
3049 key generation process in lib/silccrypt/rsa.c. The key length
3050 is now used to figure out the maximum size of the block allowed
3051 to be encrypted/signed.
3053 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3054 is equivalent to the silc_mp_mp2bin but does not allocate any
3057 * Changed silc_mp_mp2bin API to take length argument. If it is
3058 non-zero then the buffer is allocated that large. If zero, then
3059 the size is approximated using silc_mp_sizeinbase, which however
3062 * Created Global RNG API which is global RNG that application can
3063 initialize. After initializing, any routine anywhere in the
3064 code (including library) can use RNG without allocating a new
3065 RNG object. This was done to allow this sort of use of the
3066 RNG in code that has no chance to allocate RNG object. All
3067 applications currently allocate this and many routines in the
3068 library use this. Affected file lib/silccrypt/silcrng.[ch].
3070 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3071 it to use the Global RNG API.
3073 * Defined Authentication Payload into protocol specification that
3074 is used during SILC session to authenticate entities. It is
3075 used for example by client to authenticate itself to the server
3076 to obtain server operator privileges.
3078 Implemented this payload into the lib/silccore/silcauth.[ch].
3079 Implemented also routines for public key based authentication
3080 as the new protocol specification dictates.
3082 Moved definitions of different authentication methods from
3083 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3085 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3086 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3087 silc_pkcs_verify_with_hash functions into the file
3088 lib/silccrypt/silcpkcs.[ch].
3090 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * The client entry's userinfo pointer must be always valid.
3093 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3094 will fail since it requires the userinfo. Now, the userinfo
3095 is allocated as "" if actual userinfo does not exist. Actually,
3096 it must exist and it is totally Ok to drop client connections
3097 that does not announce the userinfo. However, we will make
3098 this workaround for now.
3100 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3101 to return the remote port by socket.
3103 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3106 SILC_SERVER_PENDING_EXEC and added an new macro
3107 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3108 data or when error occurs while processing the pending command.
3110 Added new argument `destructor' into silc_server_command_pending
3111 and to the SilcServerCommandPending object. This destructor is
3112 now called after calling the pending callback or if error occurs
3113 immediately. If error occurs the actual pending callback won't
3114 be called at all - only the destructor. The destructor may be
3115 NULL if destructor is not needed.
3117 All this applies for client library code as well. Similar
3118 changes were made there as well for the pending commands.
3120 In the client, the application must now allocate the
3121 SilcClientCommandContext with the silc_client_command_alloc
3124 * Added reference counter to the SilcServerCommandContext. Added
3125 function silc_server_command_alloc and silc_server_command_dup
3128 Same type of functions added to the client library for the same
3131 * Removed the cmd_ident from IDListData away since it is now
3132 global for all connections. It is the command identifier used
3133 in command sending and with pending commands. The affected file
3136 * Added reference counter to the SilcSocketConnection objecet to
3137 indicate the usage count of the object. The object won't be
3138 freed untill the reference counter hits zero. Currently only
3139 server uses this, and client ignores it. The client must be
3140 set to use this too later. The affected files are
3141 lib/silccore/silcsockconn.[ch]. Added also the function
3142 silc_socket_dup to increase the reference counter.
3144 This was mainly added because it is possible that the socket
3145 is removed underneath of pending command or other async
3146 operation. Now it won't be free'd and proper DISCONNECTING
3147 flags, etc. can be set to avoid sending data to connection that
3148 is not valid anymore.
3150 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3151 the connection. After that it sets SILC_SET_DISCONNECTED.
3152 It is, however, possible that the socket data is not still freed.
3153 The silc_server_packet_process now checks that data is not
3154 read or written to connection that is DISCONNECTED. The socket
3155 get's freed when the reference counter hits zero.
3157 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Changed the client operation API: channel_message operation's
3160 `sender' is now the client entry of the sender, not the nickname
3161 and the `channel' is the channel entry, not the channel name.
3163 In the private_message operation the `sender' is now also the
3164 client entry of the sender not the nickname.
3166 Affected file is lib/silcclient/ops.h and all applications
3167 using the client operations.
3169 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Moved the calling of ops->connect() from connect_to_server_final
3172 into receive_new_id functin since that is the point when the
3173 client is actually allowed to send traffic to network. The
3174 affected file is lib/silcclient/client.c.
3176 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3179 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3180 (if needs broadcasting) instead of broadcasting the packets one
3181 by one which would make a burst in the network traffic.
3183 * Added `broadcast' argument to the functions in silcd/server.[ch]
3184 silc_server_create_new_channel[_with_id] to indicate whether
3185 to send New Channel packet to primary router.
3187 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Added new function into the silcd/server.[ch] files:
3190 silc_server_create_new_channel_with_id to create new channel with
3191 already existing Channel ID.
3193 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3194 lib/silccore/silcpacket.h. This packet is used t send list of
3195 Set Mode payloads inside one packet. Server uses this to set
3196 the modes for the channels and clients on those channels, that it
3197 announced to the router when it connected to it. The protocol
3198 specification has been updated accordingly.
3200 * The silc_server_new_channel did not handle the packet coming
3201 from normal server as it normally does not send that. However,
3202 when it announces its channels it does send it. Implemented
3203 the support for that.
3205 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3206 into the file lib/silccore/id.h.
3208 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Fixed memory leaks in the functions silc_idlist_del_client,
3211 silc_idlist_del_channel and silc_idlist_del_server in the file
3212 silcd/idlist.c. All of those leaked like a sieve.
3214 * Fixed some small memory leaks in the client's function
3215 silc_client_notify_by_server.
3217 * Added functions into silcd/server.c: silc_server_announce_clients,
3218 silc_server_announce_channels and silc_server_announce_server.
3219 These functions are used by normal and router server to announce
3220 to its primary router about clients, channels and servers (when
3221 router) that we own. This is done after we've connected to the
3224 These functions effectively implements the following packet types:
3225 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3226 and SILC_PACKET_NEW_ID_LIST.
3228 * Added new functions into the silcd/packet_receive.[ch]:
3229 silc_server_new_id_list, silc_server_new_channel_list and
3230 silc_server_new_channel_user_list to handle the incoming
3231 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3233 * Added support of changing Channel ID in the function
3234 silc_server_replace_id. If the server that announces a channel
3235 to the router already exists in the router (with same name but
3236 with different Channel ID), router is responsible to send
3237 Replace ID packet to the server and force the server to change
3238 the Channel ID to the one router has.
3240 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3241 client that the Channel ID has been changed by the router. The
3242 normal server sends this to the client. Client must start using
3243 the new Channel ID as the channel's ID.
3245 Implemented handling of this new type into lib/silcclient/client.c
3246 into the function silc_client_notify_by_server.
3248 * Added new function silc_idlist_replace_channel_id into the files
3249 silcd/idlist.[ch] to replace the Channel ID.
3251 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Call silc_server_command_identify_check always when processing
3254 the IDENTIFY command in silcd/command.c
3256 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3259 send keepalive packets. The packet can be sent by clients,
3260 servers and routers.
3262 Added function silc_socket_set_heartbeat into the file
3263 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3264 If not set, the heartbeat is not performed. The actual
3265 heartbeat is implemented in the low level socket connection
3266 library. However, application is responsible of actually
3269 Added silc_server_send_heartbeat to send the actual heartbeat
3270 packet into silcd/packet_send.[ch]. Server now performs
3271 keepalive with all connections.
3273 * Added silc_task_get_first function into lib/silcutil/silctask.c
3274 to return the timeout task with shortest timeout. There was a bug
3275 in task unregistration that caused problems. TODO has been
3276 updated to include that task system must be rewritten.
3278 * The client library will now resolve the client information when
3279 receiving JOIN notify from server for client that we know but
3280 have incomplete information.
3282 * Rewrote parts of silc_server_remove_from_channels and
3283 silc_server_remove_from_one_channel as they did not remove the
3284 channel in some circumstances even though they should've.
3286 * Encryption problem encountered in server:
3288 The LEAVE command used to send the Channel Key packet to the
3289 router immediately after generating it. However, the code
3290 had earlier sent Remove Channel user packet but not immediately,
3291 ie. it was put to queue. The order of packets in the router
3292 was that Channel Key packet was first and Remove Channel User
3293 packet was second, even though they were encrypted in the
3294 reverse order. For this reason, MAC check failed. Now, this
3295 is fixed by not sending the Channel Key packet immediately but
3296 putting it to queue. However, this is more fundamental problem:
3297 packets that are in queue should actually not be encrypted
3298 because packets that are sent immediately gets encrypted
3299 actually with wrong IV (and thus MAC check fails). So, packets
3300 that are in queue should be encrypted when they are sent to
3301 the wire and not when they put to the queue.
3303 However, the problem is that the current system has not been
3304 designed to work that way. Instead, the packet is encrypted
3305 as soon as possible and left to the queue. The queue is then
3306 just purged into wire. There won't be any fixes for this
3307 any time soon. So, the current semantic for packet sending
3310 o If you send packet to remote host and do not force the send
3311 (the packet will be in queue) then all subsequent packets to the
3312 same remote host must also be put to the queue. Only after the
3313 queue has been purged is it safe again to force the packet
3316 o If you send all packets immediately then it safe to send
3317 any of subsequent packets through the queue, however, after
3318 the first packet is put to queue then any subsequent packets
3319 must also be put to the queue.
3321 Follow these rules and everything works fine.
3323 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Added new function silc_server_remove_clients_by_server to
3326 remove all client entries from ID list when the server connection
3327 is lost. In this case it is also important to invalidate all
3328 client entires as they hold the invalid server entry. This
3329 fixes fatal bug when server has lost connection and will reconnect
3332 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Made some sanity checks to silc_server_daemonise like to check
3335 whether the requested user and group actually exists.
3337 * Added sanity check to SKE's silc_ske_responder_finish to check
3338 that the public and private key actually is valid.
3340 * Invalidate the client's nickname when receiving Replace ID
3341 packet and the Client ID is being replaced. This means that the
3342 server will query the nickname if someone needs it (client)
3345 * Sort the ID Cache in client library when the ID Cache data
3346 has changed (needs sorting).
3348 * Do not allow for SILC client to create several connections to
3349 several servers. The client does not support windows right now
3350 and generating multiple connections causes weird behaviour.
3352 Irssi-silc client does support windows and can handle several
3353 connections without problems, see: www.irssi.org and SILC plugin.
3355 * Fixed some places where client was added to the IDList. The
3356 rule of thumb is following (in order to get everything right):
3357 If the client is directly connected local client then the
3358 `connection' argument must be set and `router' argument must be
3359 NULL to silc_idlist_add_client function. If the client is not
3360 directly connected client then the `router' argument must
3361 bet set and the `connection' argument must be NULL to the
3362 silc_idlist_add_client function.
3364 * The funtion silc_server_packet_send_local_channel actually did
3365 not check whether the client was locally connected or not. It
3366 does that now. Fixed a bug related to LEAVE command.
3368 * Fixed Remove Channel User payload parsing bug in server's
3369 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3371 * The server's silc_server_save_channel_key now checks also the
3372 global ID list for the channel as it might not be in the local
3373 list. Fixed a bug related to LEAVE command.
3375 * Is this the end of the [<unknown>] buglet that has been lurking
3376 around for a long time? A little for loop fix in server's
3377 silc_server_command_whois_parse that is used by both IDENTIFY
3378 and WHOIS command. At least, this was a clear bug and a cause
3379 of one type of [<unknown>] buglet.
3381 * WHOIS and IDENTIFY commands call the function
3382 silc_server_command_[whois/identify]_check function even if
3383 we are not router server.
3385 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Added --with-gmp configuration option. If set the GMP
3388 is always compiled in the SILC source tree. If not set then
3389 it is checked whether the system has the GMP3 installed. If
3390 it has then the GMP won't be compiled (the system's headers
3391 and library is used), if it doesn't have it then the GMP is
3392 compiled in the SILC source tree.
3394 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Changed RSA private exponent generation to what PKCS #1
3397 suggests. We try to find the smallest possible d by doing
3398 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3399 not security fix but optimization.
3401 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Added new config entry [Identity] to fork the server and run
3404 it as specific user and group. A patch from Bostik.
3406 * Imported Dotconf configuration library into lib/dotconf.
3407 This will be used to create the SILC configuration files later.
3408 It will appear in the distsribution after this commit.
3410 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * A big code auditing weekend happening. Auditing code for
3413 obvious mistakes, bugs and errors. Also, removing any code
3416 Removed files for being obsolete:
3418 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3419 inline in the file lib/silcutil/silcbuffer.h)
3421 o lib/silcutil/silcbufutil.c (the header has inline versions)
3423 Changed code to fix possible error conditions:
3425 o The buffer formatting routines now check that the destination
3426 buffer really has enough space to add the data. This applies for
3427 both buffer formatting and unformatting
3428 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3429 unformatting was changed to accomodate following rules:
3430 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3431 sent to the function while XXX_*STRING will not allocate or copy
3432 the data into the buffer. Instead it sets the pointer from the
3433 buffer into the pointer sent as argument (XXX_*STRING used to
3434 require that the pointer must be allocated already). This change
3435 makes this whole thing a bit more consistent and more optimized
3436 (note that the data returned in the unformatting with XXX_*STRING
3437 must not be freed now). The routines return now -1 on error.
3439 o Tried to find all code that use buffer_format and buffer_unformat
3440 and added return value checking to prevent formatting and
3441 especially unformatting errors and possible subsequent fatal
3444 o Changed ske->x and ske->KEY to mallocated pointers in
3445 lib/silcske/silcske.h. Fixed possible data and memory leak.
3447 o Added return value checking to all *_parse* functions. Fixed
3448 many memory leaks as well.
3450 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3451 so that buffer overflows would not happen. All code now also
3452 checks the return value as it can fail.
3454 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Added reconnection support to server if the normal server looses
3457 its connection to the router (for example if router is rebooted).
3458 The server performs normal reconnection strategy implemented
3459 to the server. Affected file silcd/server.c.
3461 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Added new packet type SILC_PACKET_SET_MODE that is used to
3464 distribute the information about changed modes (for clients,
3465 channels and clients channel modes) to all routers in the
3466 network. Updated the protocol specification accordingly.
3468 Added functions into silcd/packet_send.c and
3469 silcd/packet_receive.c: silc_server_send_set_mode,
3470 silc_server_set_mode.
3472 Added new files silcmode.[ch] into lib/silccore that implements
3473 the encoding and decoding of Set Mode Payload. Added new type
3474 SilcSetModePayload. Moved the definitions of different modes
3475 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3477 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Oops, a little mistake in server's connection authentication
3480 protocol. The protocol is not ended with FAILURE but with
3481 SUCCESS if the authentication is Ok. :) Affected file is
3484 * Implemented NICK_CHANGE notify handling in server in the file
3485 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3486 the local clients on the channel. After the changing nickname
3487 in router environment snhould work and the [<unknown>] nickname
3488 should appear no more.
3490 The silc_server_replace_id function that receives the Replace ID
3491 payload now sends the NICK_CHANGE notify type also in the file
3492 silcd/packet_receive.c
3494 * Changed WHOIS and IDENTIFY command to support the maximum amount
3495 of arguments defined in protocol specs (3328 arguments). This
3496 fixed a bug that caused problems when there were more than three
3499 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Added extra parameter, command identifier, to the
3502 silc_client_send_command so that explicit command identifier
3505 Changed that ID list routines uses specific command identifier
3506 when sending WHOIS/IDENTIFY requests to the server so that they
3507 can be identified when the reply comes back.
3509 Affected files lib/silcclient/command.[ch],
3510 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3512 * Added `sender' argument to silc_server_packet_send_to_channel
3513 to indicaet the sender who originally sent the packet to us
3514 that we are now re-sending. Ignored if NULL. Affected file
3515 silcd/packet_send.[ch].
3517 * Added some server statistics support in silcd/server_internal.h
3518 SilcServerStatistics structure and around the server code. Also
3519 send some nice statistics information when client is connecting
3522 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Fixed channel ID decoding in server's JOIN command reply in
3525 silcd/command_reply.c
3527 * Fixed braodcasting of replace ID payload to not to send it if
3528 we are standalone server in silcd/packet_receive.c.
3530 * Fixed all channel message sending routines to not to send
3531 packets to clients that has router set, since they are routed
3532 separately in the same function earlier. Affects file
3533 silcd/packet_send.c and all channel packet sending functions.
3535 * In USERS reply, res_argv[i] are not allocated, the table
3536 is allocated. Thus changed that free the table, not its
3539 * In server's whois_check and identify_check if the client is
3540 locally connected do not send any WHOIS commands - they are not
3543 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Fixed some minor bugs in client when sending WHOIS command. The
3546 arguments was in wrong order.
3548 * Removed statis function add_to_channel from server in
3549 silcd/command.c that was previously used with the joining but
3552 * Tested USERS command in router environment successfully with two
3553 routers, two servers and two clients.
3555 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Reorganized the USERS command and command reply in client library
3558 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3559 When the command is given by user we register a pending command
3560 callback that will reprocess the command after the reply has been
3561 received from the server. When reprocessing the packet we then
3562 display the information. Thus, the USERS information is displayed
3563 now in the command callback instead of in the command reply
3564 callback. The processing of the command is same as previously
3565 when server has sent the command reply in the JOINing process.
3567 * Added to USERS command in silcd/command_reply.c to join the client,
3568 we didn't use to know about, to the channel after we've created
3569 a client entry for it. Also, for clienet we did know already still
3570 check whether it is on the channel or not and add it if not.
3572 * Removed silc_server_command_join_notify as the function and its
3575 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Changed the client's pending command handling to the same as the
3578 server's pending command handling. It is also now possible to
3579 execute command reply functions from other command reply
3580 function as the function callbacks for commands and command
3581 replies are one and same. The pending commands are not static
3582 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3583 in client connection context. Thus, pending commands are server
3584 connection specific as it is convenient.
3586 Changed the function silc_client_command_pending and
3587 silc_client_command_pending_del and added new function
3588 silc_client_command_pending_check. Removed the
3589 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3592 * Added cmd_ident, current command identifier, to the client
3593 connection context in lib/silcclient/client.h to keep track on
3594 command identifiers used in command sending. Client's command reply
3595 function handling now supports the mandatory command identifiers.
3597 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3598 funtions in client to fully support pending command callbacks.
3600 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3601 as one of the arguments to the application in the command reply
3604 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3605 before first releasing SILC but came back. Now it is removed again
3606 and should come back nomore. The FORWARDED flag was used only
3607 by the JOINing procedure by forwarding the command packet to router.
3608 Now, the JOINing procedure has been changed to more generic (due
3609 to various router environment issues) and FORWARDED is not needed
3610 anymore for anything. The protocol specification is yet to be
3613 Now, removed silc_server_packet_forward from server and the flag
3614 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3616 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Renamed NAMES command to USERS command. The NAMES was named that
3619 due to historical reasons. Now it is renamed. Also, rewrote
3620 parts of the USERS command. The nickname list is not sent anymore
3621 by the server. Only Client ID and mode lists are sent in the USERS
3622 command. Changed this also to the protocol specification.
3624 The client now resolves the names and stuff after it receives
3625 the USERS list from the server when joining to the channel.
3627 * WHOIS and IDENTIFY commands has been changed to support multiple
3628 Client ID's per command. One can now search for multiple users
3629 in the network by sending only one WHOIS or IDENTIFY command.
3630 Changed the code and the protocol specifications.
3632 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3633 uses silc_server_command_whois_parse to parse the request. */
3635 * If normal server, do not parse the WHOIS and IDENTIFY requests
3636 before sending it to the router. Saves some time.
3638 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Fixed JOIN command on client library. Wrong number of arguments
3641 used to crash the client.
3643 * Added silc_server_channel_has_global function to check whether
3644 channel has global users or not.
3646 * Added silc_server_channel_has_local function to check whether channel
3647 has locally connected clients on the channel.
3649 * The silc_server_remove_from_one_channel now checks whether the
3650 channel has global users or not after given client was removed from
3651 the channel. It also checks whether the channel has local clients
3652 on the channel anymore. If it does not have then the channel entry
3653 is removed as it is not needed anymore.
3655 * The silc_server_notify now checks on JOIN notify whether the joining
3656 client is one of locally connected or global. If it is global then
3657 the channel has now global users on the channel and that is marked
3658 to the channel entry. Also, it now saves the global client to
3659 global list who is joining and JOINs it to the channel. This is
3660 for normal server, that is.
3662 Changed silc_server_send_notify_on_channel,
3663 silc_server_packet_relay_to_channel and
3664 silc_server_packet_send_to_channel check if we are normal server
3665 and client has router set (ie. global client) do not send the
3666 message to that client, as it is already routed to our router.
3668 * Implemented LEAVE notify type handling in silc_server_notify
3671 * Tested LEAVE command in router environment successfully. Tested
3672 with two routers, two servers and two clients.
3676 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3678 * Implemented SIGNOFF notify type handling in silc_server_notify
3681 * silc_server_remove_id now removes the client entry from all channels
3682 it has joined and thusly sends SIGNOFF notify type.
3684 * Rewrote the NAMES list generation in server by removing two excess
3685 loops. The lists are created now inside one loop.
3687 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * silc_server_remove_channel_user checks now also global list
3690 for channel and client.
3692 * silc_server_new_channel_user checks now both local and global
3693 list for channel and client. Fixed a bug in client id decoding.
3694 Used to decode wrong buffer.
3696 * silc_server_channel_message checks now both local and global
3697 list for channel entry.
3699 * Tested channel joining (hence JOIN) in router environment
3700 successfully. Tested with two routers, two servers and two
3703 * Tested channel message sending in router environment successfully.
3705 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Added silc_server_save_channel_key into server.[ch] to save the
3708 received channel key in Channel Key payload processing. It is
3709 also used in JOIN command reply handling.
3711 Equivalent function silc_client_save_channel_key added into
3712 client.[ch] into client library.
3714 * Changed JOIN command reply to send information whether the channel
3715 was created or not (is existing already) and the channel key
3716 payload. Changed protocol specs accordingly.
3718 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3719 the request was sent by ID and not by nickname. Crashed on
3722 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3725 now correctly save the received data.
3727 * silc_server_free_sock_user_data now notifies routers in the
3728 network about entities leaving the network.
3730 At the same time implemented functions silc_server_remove_id
3731 and silc_server_send_remove_id to receive and send REMOVE_ID
3732 packets. The packet is used to notify routers in the network
3733 about leaving entities. The ID removed will become invalid in
3736 * Added function silc_idlist_del_server into server. Removes and
3737 free's server entry from ID list.
3739 * silc_server_private_message function now checks, if we are router,
3740 that the destination ID really is valid ID, naturally.
3742 * In router when NEW_ID packet is received (for new client) the
3743 hash of the Client ID is saved in the ID Cache but the
3744 client->nickname is set to NULL, instead of putting the hash
3747 IDENTIFY command now also checks that client->nickname must be
3748 valid. If it is not if will request the data from the server who
3749 owns the client. Added new function
3750 silc_server_command_identify_check.
3752 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3753 to set the command to already allocated Command Payload.
3755 * Tested private message sending in router environment with two
3756 routers, two servers and two clients. Fixed minor bugs and now
3759 * Fixed segfault from client's NAMES command. Used to crash if
3762 * Forwarded packets must not be routed even if it is not destined
3763 to the receiver. Changed server code comply with this.
3765 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Added `require_reverse_mapping' boolean value to ServerParams
3768 structure. If TRUE (not default) the server will require that
3769 the connecting host has fully qualified domain name.
3771 If the reverse mapping is not required and hostname could not be
3772 found the IP address is used as hostname.
3774 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Implemented version string checking to both client and server.
3777 The check is incomplete currently due to the abnormal version
3778 strings used in development version of SILC.
3780 * Changed all command functions in server to use the new
3783 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Changed char *data to unsigned char *data in ID Cache system to
3786 support binary data as ID Cache data. Changed code to support
3787 binary data in lib/silccore/idcache.c.
3789 * Renamed silc_server_packet_relay_command_reply to
3790 silc_server_command_reply as it is normal packet receiving
3791 function. Rewrote the function to accept command replys for
3792 servers and not only for clients.
3794 * Mark remote router always as registered server if we are connecting
3795 to it. Otherwise, commands sent by the router to us are ignored.
3797 * All ID List find routines now returns the ID Cache Entry pointer
3798 as well if requested.
3800 * WHOIS command works now in router environment, tested with two
3801 routers, two servers and two clients.
3803 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3804 in router environment (as it is almost equivalent to WHOIS) but
3805 hasn't been tested thoroughly. Added new functions:
3807 silc_server_command_identify_parse
3808 silc_server_command_identify_send_reply
3809 silc_server_command_identify_from_client
3810 silc_server_command_identify_from_server
3812 * Disabled route cache adding because adding two different ID's with
3813 same IP replaces the old cache entry thus giving wrong route.
3814 The entry->router->connection is always the fastest route anyway
3815 so route cache may not be needed. Of course, new routes maybe
3816 established after receiving the ID when the entry->router->connection
3817 might not be anymore the most optimal.
3819 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Add route cache for received ID for fast routing.
3823 * Added silc_server_packet_route to route received packet on router
3824 that is not destined to us.
3826 * Renamed silc_server_get_route to silc_server_route_get.
3828 * Added id_string and id_string_len fields into SilcServer to
3829 include encoded ServerID for fast comparing without excess
3830 encoding of the ID's.
3832 * Cleaned up WHOIS command on server side. Added following static
3835 silc_server_command_whois_parse
3836 silc_server_command_whois_check
3837 silc_server_command_whois_send_reply
3838 silc_server_command_whois_from_client
3839 silc_server_command_whois_from_server
3841 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3842 arguments in command replies. All command functions should be
3843 updated to use this macro.
3845 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Minor typo fixes on command reply handling on server.
3849 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Added silc_server_command_add_to_channel internal routine to add
3852 the client to the channel after router has created the channel and
3853 sent command reply to the server.
3855 * Added generic silc_server_send_command to send any command from
3858 * Use static buffer with ID rendering instead of duplicating data.
3860 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Fixed a channel user mode bug when joining to a channel server gave
3863 everybody channel founder rights, oops.
3865 * We mark ourselves as the router of the incoming server connection
3866 if we are router ourselves. This way we can check in some packet
3867 sending functions whether it is locally connected server. For
3868 incoming router connections we put NULL.
3870 * For router sending packets locally means now always sending the
3871 packet cell wide; to local clients and local servers. For normal
3872 server sending packet locally means sending it to only local
3875 * Fixed the JOIN command to really work in router environment. If the
3876 channel is created it is always created by the router. Router is
3877 also responsible of making the initial joining to the channel,
3878 sending JOIN notify to the sending server and distributing
3879 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3880 does not exist server doesn't do anything else but forward the
3881 command to the router which performs everything.
3883 * Added silc_server_send_channel_key function to send the Channel Key
3886 * Added silc_server_create_channel_key to create new channel key. The
3887 channel key is now re-generated everytime someone joins or leaves
3888 a channel, as protocol dictates. Note: channel->key_len is the
3891 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3894 packet_receive.[ch] to separate packet sending and receiving
3895 routines. The server.[ch] now includes everything else including
3896 actual packet processing (writing and reading data) and other
3899 Renamed silc_server_private_message_send_internal to
3900 silc_server_send_private_message. The routine is still though
3901 used only to relay private messages as server does not send
3902 private messages itself.
3904 Renamed silc_server_new_channel to silc_server_create_new_channel
3905 and added new function sicl_server_new_channel that handles the
3906 incoming New Channel packet. Added also new sending function
3907 silc_server_send_new_channel to send New Channel Payload.
3909 * Added new function silc_server_notify to process incoming notify
3910 packet to the server/router. Server may then relay the notify
3911 to clients if needed.
3913 * Added new function silc_server_new_channel_user to process incoming
3914 New Channel User packet. Router will redistribute the packet and
3915 send JOIN notify to its local clients and locally connected servers
3916 if needed. Normal server will send JOIN notify to its local client
3917 on same channel when received this packet. Added also corresponding
3918 sending function silc_server_send_new_channel_user to sent the
3921 * Added boolean route argument to send_notif_to_channel and
3922 packet_send_to_channel functions to attempt to route the packet
3923 if it is TRUE and send only locally if it is FALSE.
3925 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * silc_server_replace_id now broadcasts the received replace ID
3928 packet if it is not broadcast packet already. The router must
3929 broadcast to inform other routers about changed ID.
3931 * Added backpointer to server's router into SilcServer context in
3932 silcd/server_internal.h.
3934 * Fixed silc_server_packet_broadcast to send correct broadcast
3937 * The channel key is now distributed to the local client as soon
3938 as it is received from the router (in router environment) so that
3939 no other packet may be sent for the channel until client has
3942 * silc_server_remove_channel_user now broadcasts the received
3943 Remove Channel User packet if it is not broadcast packet already.
3944 The router must broadcast to inform other routers about removed
3947 * Added users field into SilcPacketContext that is a reference count
3948 of the context. One can increase the reference count by calling
3949 silc_packet_context_dup which is now changed to just increase the
3950 reference count instead of duplicating the data. The reference
3951 count is decresed by calling silc_packet_context_free that will
3952 free the data after the reference count hits zero.
3954 For now on the packet context and everything allocated into it
3955 (including the raw packet from network) must be freed by calling
3956 the new silc_packet_context_free function. Added also new function
3957 silc_packet_context_alloc that must be used now to allocate the
3958 context. This also means that if a routine is asynchronous from
3959 silc_[client/server]_packet_parse_type the packet context must
3960 be duplicated by calling silc_packet_context_dup. Otherwise it
3961 gets free'd after silc_[client/server]_packet_parse_type returns.
3962 Also, one must remember that if packet is duplicated then its
3963 reference count must be decresed by calling the free function as
3964 many times as it was duplicated.
3966 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3967 from both client and server.
3969 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Made joining to a channel working in router environment.
3973 * Cleaned up JOIN command on server side and create function
3974 silc_server_command_join_channel internal routine to make the
3977 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Changed silc_command_pending list to SilcDList. Also, added
3980 `ident' field to SilcServerCommandPending structure to identify
3981 the reply and to call correct callback.
3983 Added silc_server_command_pending_check function to replace the
3984 corresnponding macro. The silc_command_pending list is not
3987 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3988 to set identifier to previously allocated Command Payload. It
3989 is used to set identifier for command when resending Command
3992 * Added silc_command_payload_encode_payload to encode Command
3993 Payload buffer from SilcCommandPayload structure.
3995 * Added silc_argument_payload_encode_payload to encode Argument
3996 payload buffer from SilcArgumentPayload structure.
3998 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Changed WHOIS command to support router connection on server side.
4001 The whois request is always sent to router unless the server is
4002 standalone server. After server has received the reply from the
4003 router will it send the reply to the client.
4005 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4006 broadcast received broadcast packet. The function is used only
4007 by router. The broadcast packet is always sent to the router's
4010 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4011 render given ID to printable string, for log files for example.
4013 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Made basic router to router connections working. At least they
4016 can now connect to each other but nothing really works the way
4017 they are supposed - yet.
4019 * Added new initiator token to RouterConnection configuration
4020 file in silcd/serverconfig.[ch]. It is used to tell whether we
4021 are the initiator to the remote router or whether we'll expect
4022 the other end to connect.
4024 * Moved registering of listener task to silc_server_init, hence
4025 the server starts listenning as soon as it is run, even if it
4026 does not have connections to other routers. Let's see how well
4029 * Changed default connection retry timeouts for more suitable in
4032 * Removed cipher and such arguments from silc_idlist_add_client
4033 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4034 Added new function silc_idlist_add_data to add the keys and stuff
4037 * Added SilcIDListData structure and added it to SilcClientEntry
4038 and SilcServerEntry as their first field in the structure. This
4039 way we can explicitly cast the ID entries to the SilcIDListData
4040 structure and get common data for the entries. In past, we had
4041 to first check what type of connection it is and then cast it to
4042 correct ID entry type. Now, we can directly cast the opaque
4043 pointer to the SilcIDListData (no matter what ID entry it actually
4044 is) and get the data needed.
4046 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4049 in some circumstances even if threre were timeout tasks, though not
4050 IO tasks, but tasks anyway. Now fixed.
4052 * Defined SilcServerConnection structure to hold connection specific
4053 stuff about directly connected servers and routers. The definition
4054 is currently in silcd/server_internal.h. I thought about having
4055 a bit more important role fro this struct but for now it is used
4056 only when connecting to other server (or router actually).
4058 * Added connecting retry support in server when connecting to
4059 router(s). The retry feature implement exponential backoff
4060 algorithm. Also, added SilcServerParams structure to hold default
4061 parameters for server. For now, it include these retry settings
4062 and are hard coded. After server is moded to be as Silc Server
4063 Library this structure will be more important.
4065 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Changed client librarys channel->clients table to SilcList and
4068 changed code accordingly.
4070 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Changed client's channel table to SilcList and changed code
4073 accordingly. Also changed SilcChannelClientEntry to include back-
4074 pointer to the channel so that client entry can use that structure
4075 as list as well and we have fast cross-reference to the channel.
4076 This change dramatically decreased the complexity of channel
4077 handling with client entry and vice versa (removed one extra
4078 loop when searching for channel entry from many functions).
4080 * Changed server->sim from table to SilcDList and changed code
4083 * NAMES command can now be used from user interface. It will show
4084 the user list on the channel, neatly.
4086 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4087 Code now saves realname of the user if it becomes available.
4089 * Renamed configure.in to configure.in.pre and made ./prepare
4090 script to automatically add correct version string to
4091 configure.in which it creates from configure.in.pre.
4093 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * NAMES command reply now shows users mode with the nickname when
4098 * Moved silc_client_ch[u]mode[_char] functions from
4099 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4100 place sucks, they are utility functions and should be in some
4103 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4105 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4108 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * Added TRQ (efficient deque and list library) into lib/trq. This is
4113 a very good list library that is currently used in the SILC. Defined
4114 SilcList API over the library because I didn't like the API very
4115 much. See lib/trq/silclist.h for the API and examples of how to
4116 use the API. Fixed various places in the code to use the new
4117 SilcList API. The SilcList is meant for lists that has a structure
4118 already defined as a list. It is not suitable to add just some
4119 context to the list (in TRQ, the context is the list actually).
4121 So, I defined SilcDList that can be used for the purpose where
4122 predefined list structure does not exit. This can be used as
4123 such list. Now some context just can be added to the SilcDList.
4124 Currently this list is not used in the SILC just yet, though there
4125 are a lot places where this can replace dynamically allocated
4126 tables and I will fix these places, later, to use SilcDList.
4127 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4128 and use TRQ internally).
4130 Also fixed some annoying warning messages that the original TRQ
4131 code generated. Also minor changes to TRQ's Makefile.in.
4133 * Added support for querying by Client ID to both WHOIS and
4134 IDENTIFY commands into server, as required by the protocol.
4136 * Removed method function pointers from SilcBuffer structure. They
4137 weren't used to anything and just increased the context size for
4138 no good reason. This change also made silc_buffer_alloc and
4139 silc_buffer_free functions inline functions.
4141 * Disabled command flooding detection support until it's fixed so
4142 that it accepts commands in but does not execute them more than once
4145 * Added silc_net_localhost(), to return local hostname, into
4146 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4147 that must be initialized before calling silc_client_init.
4149 * Added new function: silc_server_send_notify_on_channels to send
4150 notify messages to all channels client has joined. It is assured
4151 that the message is sent only once per client.
4153 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4154 lib/silcutil/silcutil.[ch] as silc_format function. The new
4155 function is generic and is used by server as well, not only by
4156 the logging routines.
4158 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4159 the provided version string was not acceptable. Added new function:
4160 silc_ske_check_version into lib/silcske/silcske.h. The function
4161 must be implemented by the application (client or server) and it
4162 does not reside in the SKE library. The function checks the version
4163 string remote end sent.
4165 * Added back pointers (to opaque context and to SilcSocketConnection)
4166 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4168 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4169 duplicate packet context structure.
4171 * Changed `notify' client operation to send same arguments as client
4172 receives from server except for ID's. ID's are mapped to correct
4173 ID entry and that is returned. Also, if channel entry is not sent
4174 by server but the notify is for channel the channel entry is sent
4175 to application (otherwise application doesn't know that it is for
4176 channel (library gets it from packet's Destination ID)).
4178 * Added silc_client_remove_from_channels into client library to
4179 remove a client from all channels it has joined to. Used when
4180 received SIGNOFF notify from server. Added also new function
4181 silc_client_replace_from_channels to replace old ID entry with
4182 new ID entry on all channels. Used when received NICK_CHANGE
4185 * Fixed ID Cache list handling in silc_idlist_get_client in
4186 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4187 to get (or query) client by ID.
4189 * Updated TODO list.
4191 * Added connection authentication status message defined by the
4192 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4193 support for these into the code in client and server side.
4195 * Added generic function silc_client_send_command to send any command
4196 with variable argument list. Application should use this function
4197 to send commands if the command functions provided by the library
4198 does not suite for the application's user interface needs.
4200 * Added new `failure' client operation. Application is notified about
4201 received failure packet if client is executing a protocol. In this
4202 case the protocol's execution has failed.
4204 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4205 is required by the protocol.
4207 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4208 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4211 * Added status flag to SilcSKE object to indicate realtime status
4212 of the SKE protocol.
4214 * Application receives now exactly same command reply arguments as
4215 the library receives from server. However, if ID is received the
4216 corresponding ID entry is returned to the application (eg. Client
4217 ID is mapped to correct SilcClientEntry entry and that is returned).
4218 Changed command_reply client operation due to this change.
4220 * Changed all ID's in commands and in command replys as ID Payloads.
4221 Change affected both client and server side codes.
4223 All ID's sent in SILC network (with execption of ID's in SILC
4224 Packet header) are sent in ID Payload to support variable length
4227 * Server now notifies nick changes and notifies all clients on
4228 the channels about the new nickname (about the new Client ID,
4231 * Implemented CMODE command to change channel modes. Supports all
4232 channel modes defined by the protocol specs except ban and invite
4233 lists. (Also, private channel key mode is supported but support for
4234 setting private channel key in client is missing, thus, this mode
4235 has no effect on client side (except that server requires that the
4236 client uses private channel key and normal channel traffic does not
4239 Also, invite mode works per se, but INVITE command does not work
4240 yet correctly, so you can set channel as invite only channel but
4241 inviting clients to the channel does not work (it is yet to be
4242 thought what's the best way to do it).
4244 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4245 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4246 Implemented CUMODE command to change user's mode on the channel.
4247 Supports all modes defined by the protocol specs.
4249 * Added NAMES command reply to return users modes on the channel.
4251 * Removed unnecessary and slow ciphers from lib/silccrypt.
4253 * Set SO_KEEPALIVE option to connection sockets by default.
4255 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4257 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4258 redefined the Notify Payload into protocol specs.
4260 * Added silc_id_payload_parse_id to get ID directly from raw
4263 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4266 accept searching by Client ID as well.
4268 * Added support for LEAVE and SIGNOFF notify types in client library.
4270 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4271 to parse ID Payload from raw data.
4273 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Added flags parameter into silc_ske_assemble_security_properties
4276 function in lib/silcske/silcske.[ch].
4278 * Changed notify client operation to fit better for notify messages
4279 sent by server. The notify payload received from server is now
4280 passed to the application (after parsing it to SilcNotifyPayload).
4281 It is application's responsibility to retrieve the arguments
4282 from the payload and show the message the way it wants. The message
4283 sent by server is implementation specific.
4285 * Changed public keys to comply with the protocol specification.
4286 Old public keys are not supported anymore and are not compatible.
4288 * Removed nickname from Channel Payload as the latest draft removed
4289 it. The client must resolve the nickname from the NAMES command
4290 reply received when it joined the channel.
4292 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4294 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Fixed some errors in protocol specification drafts.
4298 * Created lib/silccore/silcnotify.c to implement Notify Payload
4299 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4300 generic payloads described by protocol specifications. The file
4301 includes implementations for ID Payload and Argument Payload.
4303 * Changed Command Payload implementation to use the new Argument
4304 Payload. Changed command_xxxx_payload to command_payload_xxxx
4305 to comply with SILC coding conventions.
4307 * Added suppport for Argument Payload handling in Notify Payload
4308 implementation as protocol requires it. Added the new support
4309 into server and client lib as well.
4311 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Added support for multiple nicknames on same channel. [n] is
4314 added locally to the nickname if there are more than one same
4315 nicknames on the channel.
4317 * Server now sends all nicknames that matched WHOIS request.
4318 Client also shows the list received from server.
4320 * Added TOPIC command to client side. User can now set and show
4321 current topic on channel.
4323 * Added MOTD command to client and server. Also, server sends the
4324 motd when client connects to the server.
4326 * Changed version strings to comply ISO 8601.
4328 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Fixed protocol error handling in client library. It should now
4331 cope even if the SKE fails for some reason.
4333 * Made new protocol specification drafts for submitting to IETF.
4335 * Implemented TOPIC command to server in silcd/command.c.
4337 * Added two new notify types into lib/silccore/silcnotify.h:
4338 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4339 notify nickname change and topic setting/change on a channel.
4341 * API change of command_reply operation in client library. The
4342 application gets now the status type received from server as well.
4344 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4348 * Cras fixed and optimized the packet handling even further and
4349 it should work now. Minor change to the prototype of function
4350 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4352 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Added new function into lib/silcutil/silcschedule.[ch]:
4355 silc_schedule_with_fd to select() a specified fd. The function
4356 returns after timeout expires or data arrives or goes. The
4357 function is used by packet routines to wait that all data is
4358 received from network.
4360 * Fixed data reading from network in lib/silccore/silcpacket.c.
4361 The code now assures that all data is read from the fd and then
4362 continues packet processing. This was a bug fix since the code
4363 used to drop some data in some circumstances.
4365 * Added new function into lib/silcclient/client.[ch]:
4366 silc_client_start_key_exchange to start key exchange after
4367 connection has been established to server. The code internally
4368 now uses this funtion but its main purpose was to provide it
4369 for applications that perform their own connecting. After
4370 application has created a connection it merely calls this
4371 function to start the key exchange between client and server.
4372 The library takes care of everything else after that.
4374 Updated also lib/silcclient/README to explain the usage of
4377 * Do not send to application information that connection has
4378 been established. Application gets notified it by connect
4381 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Applied cras's patch to add silc_schedule_one function. The
4384 function runs scheduler once and returns.
4386 * Fixed the scheduler after cras messed it up. The timeout
4387 handling works now as it's supposed to work.
4389 * Added into lib/silccore/ silcnotify.h to include notify
4390 message types support. Changed silc_server_send_notify*
4391 functions, in server.[ch], to support those new notify types.
4392 Added the support for the notify types into client library,
4393 as well. Added new notify client operation into ops.h in
4396 * Changed silc_server_packet_send_to_channel to send normal
4397 packets instead of just channel message packets. The function
4398 is now used to send the notify packets to channels. It is not
4399 used to send channel message packets anymore, as server never
4402 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4403 va_arg()s as it seems to require it nowadays. I guess, if SILC
4404 is compiled with older va_arg() the new code should work anyway.
4406 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Splitted core library. Core library (lib/silccore) includes
4409 now only SILC protocol specific core (and common) components.
4410 Created new utility library (lib/silcutil) that includes more
4411 generic purpose stuff. The stuff for util library was taken
4412 from the old core library. This was minor and easy split.
4414 * Created SILC Client Library (lib/silcclient) that includes
4415 implementation of the SILC client without user interface. This
4416 was major move from silc/ directory. The code has been changed
4417 so that it is transparent towards the user interface. The
4418 silc/ directory includes now the same user interface as before
4419 and it uses the new client library. Read lib/silcclient/README.
4420 Basicly, the client library performs everything else related
4421 to SILC except user interface handling. Also, configuration
4422 files are considered to be part of user interface and library
4423 does not handle them.
4425 This change also changed a lot of structures, function naming etc.
4426 Most important change was that SilcClientWindow object was
4427 renamed to SilcClientConnection in the client library. Created
4428 also new file lib/silcclient/ops.h. Also added new files
4429 silc/local_command.[ch] and silc/client_ops.[ch].
4431 All these changes were made to make it easier for user interface
4432 designers to create what ever user interface for the SILC client
4435 It is also expected that the server will be moved to lib
4436 directory as well and SILC Server Library will be created;
4437 sometimes in the future.
4439 * Removed Local commands from lib/silccore/silccommand.h as
4440 they are application specific and new client library does not
4441 handle any of those anymore.
4443 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4444 old client implementation in silc/.
4446 * Added support for callback functions in SILC_LOG_* macros.
4447 Application can now set its own callbacks that will be called
4448 instead of using the default functions that will always print
4449 the debug messages to stderr (or stdout). Also, debugging can
4450 now be disabled by setting silc_debug to FALSE and re-enabled by
4451 setting it to TRUE. Note, that logging will still work even
4452 if debugging is disabled.
4454 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4455 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4456 silc_log_reset_debug_callbacks.
4458 * To enable debugging in silc client one must give now -d
4459 option on command line.
4461 * Changed silc_schedule_init to automatically allocate task queues
4462 if they are not allocated before calling it.
4464 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added GMP 3.1 into math library.
4468 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4471 a channel in SILC network. The packet is used by servers and
4472 routers to notify other routers that user has left a channel.
4473 This little feature was missing until now. Added the feature
4474 to protocol specification as well.
4476 Added functions: silc_server_send_remove_channel_user and
4477 silc_server_remove_channel_user into server.[ch].
4479 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4480 lib/silccore/silcpacket.h. However, they are not implemented
4483 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Fixed joining to a channel and sending channel messages
4486 between server and router. The channel message sending should
4487 now work inside a cell.
4489 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Fixed the private message sending between server and router.
4492 The private message sending should now work inside a cell.
4494 * Added silc_server_replace_id into server.[ch] to replace
4495 existing ID in the SILC network.
4497 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4498 and silc_idlist_replace_server_id into idlist.[ch] in server.
4500 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Fixed the server to server connections. Server can again now
4503 connect to router. Router to router connections probably does
4506 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added dynamic protocol registering support. Now protocols can
4509 registered and unregistered on the fly. Patch by cras.
4511 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Added lib/contrib directory to hold routines that some platforms
4514 don't have but are needed by SILC.
4516 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4517 into lin/contrib to provide getopt() and getopt_long() for
4518 those who don't have it.
4520 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Added AWAY command to client. When away message is set and
4523 client receives a private message packet the client automatically
4524 replies to the sender with the away message.
4526 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4527 bug seemed to be the cause of recent problems when compiling
4530 * Added version detection support to SKE protocol specification
4531 and added the new changes to the SKE implementation as well.
4532 There were other minor changes in the SKE protocol as well.
4534 Many changes in lib/silcske/silcske.[ch] and in
4535 lib/silcske/payload.[ch].
4537 * Added ^U functionality, clear input line. Patch from cras.
4539 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Mainly small bugfixes on core library. Fixed some debugging
4542 logging and buffer overflow in silclog.c.
4544 * Updated config.sub and config.guess on the distribution tree.
4546 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Added command lagging support in server. Client may execute
4549 commands now only once in two seconds.
4551 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Optimized packet reception. MAC computation and checking is now
4554 also more optimized. A lot previously duplicated code is now
4555 used as generic by both client and server.
4557 * Fixed key pair generation in clientutil.c
4559 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Added into lib/silccore/silcbufutil.[ch] new function;
4562 silc_buffer_realloc.
4564 * Moved generic packet sending/encryption functions to
4565 lib/silccore/silcpacket.[ch] from client and server. Some
4566 rewriting of the functions.
4568 * Moved all generic packet reception/decryption functions to
4569 lib/silccore/silcpacket.[ch] from client and server. The
4570 packet processing is now much cleaner in both client and server.
4571 These were major changes in both client and server.
4573 * Created many common functions in server to do packet sending.
4574 Previously code were duplicated a lot, this has been removed
4577 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Rewrote major parts of the ID cache system. Don't know
4580 whether it is better now or not but at least the API is more
4583 * Major rewrite on ID cache stuff on client because of the ID
4584 cache API changes. Added idlist.c to client.
4586 * Also major rewrite on ID cache stuff on server as well.
4587 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4588 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4589 in hand, instead they are all put into the ID cache system now.
4590 All server_idlist_* routines uses ID cache now instead of
4591 traversing its own lists (those lists does not exist anymore).
4592 SilcIDList though still exists. Also, SilcXXXEntry's are
4595 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Finally made the SKE implementation compliant to the protocol
4598 specification. All mp integers are now binary encoded as
4599 opposed being HEX encoded.
4601 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4604 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4605 functions: silc_[encode/decode]_pem. Also added function
4606 silc_encode_pem_file to PEM encode with newlines ('\n') for
4609 * SILC public keys are now encoded either PEM or binary. Same
4610 option is for private keys as well. By default private keys
4611 are binary encoded and public keys PEM encoded. Silly HEX
4612 encoding were removed.
4614 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4615 function to create fingerprints.
4617 * Fixed a bug in SHA1; does not change the original data anymore.
4619 * Partly implemented INFO command on client and server side.
4620 Fixed CLEAR command. Changes to SERVER command; show current
4621 server(s) when giving command without arguments. Added
4622 VERSION command to client.
4624 * Added check to server that unregistered connections cannot
4625 execute commands (unless it is specificly allowed).
4627 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Fixed screen refresh.
4631 * Fixed channel joining bug from client. On some circumstances
4632 client tried to join to a channel it had already joined.
4634 * Added public key verification process into client's protocol.c.
4635 The client now verifies the public key from user and saves
4636 it into ~./silc/serverkeys/ directory.
4638 Added into: clientutil.[ch]: silc_client_verify_server_key.
4640 * Changed SKE protocol's silc_ske_initiator_finish function
4641 to accept callback function that verifies the received public
4642 key. Removed old silc_ske_verify_public_key function.
4644 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4647 silc_pkcs_private_key[_data]_set.
4649 * Made the password and public authentication more cleaner in
4650 server's protocol.c.
4652 * Removed historic and obsolete protocol `channel_auth' from
4653 both client and server.
4655 * Removed wrong way of sending command status messages from
4656 server to client in server's command.c. The old way violated
4657 protocol specification.
4659 Changes to silccore/silccommand.[ch]: removed
4660 silc_command_encode_status_payload -> not needed anymore,
4661 changed silc_command_encode_payload_va to accept extra
4662 argument on variable argument list. The argument type must
4663 now be provided to the function. Also, added new function:
4664 silc_command_encode_reply_payload_va which is same as
4665 normal command_encode_payload_va except command status type
4666 is provided as extra argument.
4668 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Added ~./silc directory handling. The directory includes the
4671 public and private keys for the client.
4673 Added silc_client_check_silc_dir, silc_client_create_identifier
4674 and silc_client_load_keys.
4676 * Implemented SILC protocol compliant public key. Added public
4677 and private key saving to and loading from files.
4679 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4680 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4681 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4682 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4683 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4685 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4686 silc_pkcs_load_[public/private]_key.
4688 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Added silc_server_get_route (route.[ch]) to get connection
4691 data for the fastest route for given ID.
4693 * Implemented INVITE command on client and server. The command
4694 were re-defined in the SILC Protocol Specification and the
4695 implementation now complies with the specification.
4697 * Implemented PING command on client and server.
4699 * Implemented NAMES command on client and server. The server side
4700 supports currently only normal server not router server yet.
4701 Some changes to NAMES definition in SILC protocol specification.
4703 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Implemented LEAVE command on client and server.
4707 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4708 again. This change was made to the protocol as well. Server
4709 should not violate the protocol specification anymore.
4711 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4714 was tested. SOCKS4 was not but should work anyway.
