1 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added `task_max' field to the SilcClientParams to indicate
4 the maximum tasks the scheduler can handle. If set to zero,
5 default values are used. Affected file lib/silcclient/silcapi.h.
7 * Fixed memory leaks in silc_client_close_connection. Affected
8 file lib/silcclient/client.c.
10 * Added silc_client_del_client_entry to client library to free
11 all memory of given client entry. Affected file is
12 lib/silcclient/idlist.[ch].
14 * Added new functions silc_client_del_channel and
15 silc_client_del_server to delete channel and server entries.
16 Affected file lib/silcclient/[silcapi.h/idlist.c].
18 * Removed silc_client_del_client_by_id from silcapi.h.
20 * Fixed the INFO command to return the server's own info
21 correctly when querying by Server ID. Affected file is
24 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
26 * Removed the non-blocking settings in WIN32 code in the
27 silc_sock_[read/write] and added SleepEx instead. Affected
28 file lib/silcutil/win32/silcwin32sockconn.c. The availability
29 of input data is now checked with FIONREAD and ioctlsocket.
31 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
33 * Call silc_schedule_task_del_by_context in the
34 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
35 Affected file lib/silccore/silcprotocol.c.
37 * Call silc_protocol_cancel for active protocols in the
38 silc_server_close_connection if the funtion
39 silc_server_free_sock_user_data has not been called.
40 Affected file silcd/server.c.
42 * Generic tasks cannot be deleted using the del_by_fd
43 task deleting function since generic tasks does not match
44 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
46 * Added a notion to SILCOPER help file that the SILCOPER works
47 only on router server, not on normal server.
49 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Added for WIN32 support for the new scheduler as well.
52 Affected file lib/silcutil/win32/silcwin32schedule.c.
54 * Fixed the SHA1 implementation to work on various platforms.
56 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
58 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
59 API. It is part of the scheduler now. Everything else is
60 as previously but some functions has changed their names.
61 Checkout the lib/silcutil/silcschedule.h for the interface.
62 Updated all applications to use the new interface. Affected
63 files are lib/silcutil/silcschedule.[ch].
65 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
67 * Found a bug in the SKE implementation. The HASH value,
68 specified by the protocol, was not computed correctly. The
69 public key of the responder was not added to the computation
70 even though it is mandatory. Affected file lib/silcske/silcske.c.
71 This unfortunately causes incompatibilities with older
74 * Added WIN32 specific network init and uninit functions:
75 silc_net_win32_init and silc_net_win32_uninit to init and uninit
76 the Winsock2. Affected file lib/silcutil/silcnet.h and
77 lib/silcutil/win32/silcwin32net.c.
79 * Set the socket always to nonblocking mode on WIN32 after
80 reading data or writing data. Affected file is
81 lib/silcutil/win32/silcwin32sockconn.c.
83 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Fixed various compilation problems under WIN32. Affected
86 files lib/silcutil/win32/silcwin32thread.c and
87 lib/silcutil/win32/silcwin32schedule.c.
89 * Removed all _internal.h #includes from public header
90 files. Internal headers must never be included from
93 Removed also the lib/silcske/payload_internal.h file.
95 * All include files that may be needed (public and some others
96 included by the public headers) by application developers are
97 now copied to the ./includes directory. It does not copy any
98 internal headers. Affected file Makefile.defines.pre and all
99 Makefile.am's under lib/ and subdirs.
101 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Do not change the ~/.silc directory's permissions automatically.
104 Affected file irssi/src/silc/core/clientutil.c.
106 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
108 * Do not cancel the protocol in silc_server_close_connection
109 it might cause recursion. Now cancelled in the function
110 silc_server_free_sock_user_data. Affected file silcd/server.c.
112 * Fixed the silc_server_remove_clients_by_server to regenerate
113 the channel keys correctly finally. Added also new function
114 silc_server_remove_clients_channels to actually do it.
115 Affected file silcd/server.c.
117 * Fixed the silc_server_new_channel to not crash by giving
118 wrong router to the new channel. Affected file is
119 silcd/packet_receive.c.
121 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
123 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
124 which is given as argument to the silc_client_alloc now.
125 It can be used to configure the client and set various parameters
126 that affect the function of the client.
128 * The USERS command in server did not check whether the channel
129 is private or secret. Affected file silcd/command.c.
131 * Added new argument to the USERS command in protocol specification.
132 The USERS command now can take the channel name as argument
133 as well. Added support for this in client and server and
134 updated the protocol specs.
136 * Completed the GETKEY command in client. It can be now used
137 to fetch also servers public key not only some clients.
138 Affected files lib/silcclient/command[_reply].c.
140 * Added silc_client_get_server to return server entry by the
141 server name. Affected files lib/silcclient/silcapi.h and
144 * Redefined the IDENTIFY command in protocol specification to be
145 more generic. It now can be used to query information about
146 any entity in the SILC Network, including clients, servers and
147 channels. The query may be based either the entity's name
148 or the ID. Added support for this in both client and server.
150 Affected files silcd/command.c and lib/silcclient/command.c
153 * Optimized the WHOIS and WHOWAS commands in the server. Removed
154 the _from_client and _from_server functions. Affected file
157 * Added silc_client_get_channel_by_id_resolve to the file
158 lib/silcclient/silcapi.h to resolve channel information by
159 its ID. Added also silc_client_get_channel_by_id that
160 does not resolve it from the server.
162 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
164 * Added SilcServerEntry context into the client library
165 to represent one server. The INFO command now allocates
166 these to save the resolved server info. For now on the
167 client library will also keep information about servers,
168 connected and resolved with INFO.
170 The INFO command now allocates the SilcServerEntry context
171 and saves the server info there. The COMMAND_REPLY in
172 the INFO now returns the parameters to application in
173 same order as defined in the protocol specification.
175 The entries are cached in the client->server_cache.
177 * The INFO command is now issued after received the Client ID
178 from the server. Affected file lib/silcclient/client.c.
180 * The CMODE_CHANGE notify may now return also an SilcServerEntry
181 to the application as the mode changer might be server.
182 It is guaranteed that NULL is not returned anymore to the
183 application. Affected file lib/silcclient/client_notify.c.
185 The ID Type is now also passed to the application so that
186 it can check whether the returned entry is SilcClientEntry
189 Added new function silc_client_get_server_by_id to return
190 the server entry by ID. Affected files are the
191 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
193 * Do not create the channel in the Irssi SILC Client when issuing
194 the JOIN command but when received the sucessful JOIN command
195 reply. Otherwise the channel might get created even though we
196 could not join it. The Affected file is
197 irssi/src/silc/core/[silc-channels.c/client_ops.c].
199 * Fixed a channel joining bug in router. The router must also
200 check the channel modes, invite and ban lists etc. when serving
201 the JOIN command sent by normal server. Affected file is
202 silcd/command.c. The router now resolves the client's
203 information from the server who sent the JOIN command if it
204 does not know it, and processes the JOIN command only after
207 * Changed the SilcCommandCb to take new argument; void *context2.
208 Affected file lib/silccore/silccommand.h
210 The second argument in the command callbacks in the server now
211 includes the SilcServerCommandReplyContext if the command was
212 called as pending command callback from the command reply.
213 Otherwise it is NULL. When called as pending the status of the
214 command reply will be checked and if it was erronous the
215 error will be sent to the original sender of the command.
216 This way the client always receives the error messages even
217 though the server was actually the one who received the error
218 when it resent the command to router, for example. Affected
219 files silcd/command[_reply].[ch].
221 * Fixed sending WHOWAS command's error message to client if
222 the requested client could not be found. It was missing.
225 * Changed the CMODE and CUMODE commands reply arguments in the
226 protocol specification. The Channel ID is now sent in both
227 of the commands to identify the channel. Implemented this
228 new feature to the client and server. Affected files
229 lib/silcclient/command_reply.c and silcd/command.c.
231 * Made better checks for invite and ban lists in the JOIN
232 command in server. Affected file silcd/command.c.
234 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
236 * The server now performs the incoming host IP/DNS lookup
237 using the silc_socket_host_lookup and thus does not block
238 the server anymore. Affected file silcd/server.c.
240 * Completed the multi-thread support for SILC Scheduler in
241 the lib/silcutil/silcschedule.c.
243 * Fixed the configure.in.pre to detect the pthread correctly
246 * Fixed a deadlock in silc_task_queue_wakeup in the file
247 lib/silcutil/silctask.c.
249 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
251 * Added new function silc_schedule_wakeup that is used in
252 multi-threaded environment to wakeup the main thread's
253 schduler. It needs to be used when a thread adds a new task
254 or removes a task from task queues. After waking up, the
255 scheduler will detect the task queue changes. If threads
256 support is not compiled in this function has no effect.
257 Implemented the wakeup mechanism to both Unix and WIN32
258 systems. Affected files are lib/silcutil/silcschedule.[ch],
259 lib/silcutil/unix/silcunixschedule.c and the
260 lib/silcutil/win32/silcwin32schedule.c.
262 * Added new function silc_task_queue_wakeup to wakeup the
263 scheduler by the specified task queue. Affected file
264 lib/silcutil/silctask.[ch].
266 * The silc_socket_host_lookup_start now wakes up the scheduler
267 after adding the timeout task. Affected file is
268 lib/silcutil/silcsockconn.c.
270 * The silc_socket_host_lookup is synchronous now if the threads
271 support is not compiled in. However, the callback is still
272 called asyncronously through the scheduler, anyway. Affected
273 file lib/silcutil/silcsockconn.c.
275 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Added new function silc_socket_host_lookup to perform
278 asynchronous IP and FQDN lookups for the socket connection.
279 Affected files lib/silcutil/silcsockconn.[ch].
281 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
283 * Added SILC_MUTEX_DEFINE to define the mutex on environments
284 that may or may not compile the mutex support in.
286 Changed the silc_mutex_alloc interface. It allocates the
287 mutex now to the sent pointer and returns TRUE or FALSE.
289 Affected file lib/silcutil/silcmutex.h.
291 * Wrote the SILC Task Queue interface to support multi-threads.
292 Affected file lib/silcutil/silctask.[ch].
294 * Wrote the SILC Scheduler to support multi-threads. Affected
295 file lib/silcutil/silcschedule.c.
297 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Implemented the SILC Mutex API and SILC Thread API for WIN32
300 in lib/silcutil/win32/.
302 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
304 * Defined SILC Mutex API and SILC Thread API and implemented
305 them for Unix. Affected files are
306 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
307 lib/silcutil/unix/silcunixmutex.c and
308 lib/silcutil/unix/silcunixthread.c.
310 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Fixed the silc_server_remove_clients_by_server's channel
313 key re-generation. The hash table handling was incorrect
314 and would not work with many channels. Affected file is
317 * Fixed some memory leaks around the server code.
319 * Rewrote the silc_server_get_users_on_channel to support IPv6
320 based Client ID's. Affected file silcd/server.c.
322 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
323 specification. However, a separate document must be written
324 to define the detailed signing procedure and the payload
325 associated with the flag. Defined the flag to the
326 lib/silccore/silcchannel.h as well.
328 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Changed the dynamic tables to static size tables in the
331 lib/silccrypt/silchmac.c.
333 * Removed GCC dependencies from the code. A patch by cras.
335 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Do not show the error "Error receiving packet bla bla"
338 in server if it really was not an error (-2 means that reading
339 is pending). Affected file silcd/server.c.
341 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
343 * Fixed a possible crash in silc_server_remove_clients_by_server
344 in silcd/server.c. Fixed there also some memory leaks.
346 * Fixed the silc_idlist_replace_client_id. It could replace
347 wrong key in the hash table. Affected file silcd/idlist.c.
349 * Do not check whether there are global users on the channel
350 if the channel->global_users is FALSE. Affected functions
351 silc_server_remove_from_one_channel and
352 silc_server_remove_from_channels in silcd/server.c. Also,
353 do not check if the removed client is local as we can be
354 sure that global client was not removed from the channel
355 and checking for global users is not needed.
357 * The silc_server_remove_clients_by_server now re-generates
358 the channel keys correctly for those channels that had
359 clients removed from them. Affected file silcd/server.c.
361 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Found the reason of random crashes in the server. We weren't
364 ignoring the SIGPIPE signal (which can be sent in write())
365 and it crashed the server. Affected file silcd/silcd.c.
367 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Assure that sock->user_data is not NULL in the function
370 silc_server_packet_send in silcd/packet_send.c.
372 * Disconnect the remote connection if it could not be added
373 to any ID lists in the server. The affected file is
376 * Check in silc_server_packet_send[_real/dest] that the
377 socket is not disconnecting and ignore the data if it is.
378 Affected file silcd/packet_send.c.
380 * Define inline to __inline on native WIN32 compilation.
381 Affected file includes/silcwin32.h.
383 * Added some explicit type casts for inline code since MSVC
384 require them. Affected files lib/silcutil/silcbuffer.h,
385 lib/trq/silcdlist.h and lib/trq/silclist.h.
387 * Print warning in log files from now on if the packet
388 decryption fails. Affected file silcd/server.c.
390 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
392 * Changed the `say' client operation's interface to accept
393 new `type' argument to indicate the type of the message sent
394 by the library. The application may filter the library's
395 messages according the type. The affected file is the
396 lib/silcclient/silcapi.h.
398 * Added two new functions to lib/silcclient/silcapi.h:
399 silc_client_del_client and silc_client_del_client_by_id.
400 Affected file lib/silcclient/idlist.c.
402 * Moved the clientincludes.h from includes/ to silc/ and
403 serverincludes.h from includes/ to silcd/.
405 * The modes for the CMODE and CUMODE are now passed as
406 uint32 for application with COMMAND_REPLY. The affected
407 file is lib/silcclient/command_reply.c.
409 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
411 * /WHOIS without arguments shows client's own information.
412 Affected file lib/silcclient/command.c.
414 * Changed PING to not accept any arguments. The specs
415 says that client can ping only the connected server so
416 requiring an argument is not needed. Affected file is
417 lib/silcclient/command.c.
419 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Fixed a fatal bug in private message sending and reception
422 encryption and decryption when using private message keys.
423 The implementation was incorrect and did not follow the
424 specification. It causd that some of the message were
425 lost since it did not use the sending and receiving keys
426 as the protocol suggests. This has been fixed and will cause
427 incompatibilities with older clients when sending private
428 message encrypted with private message keys. Affected files
429 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
430 and various other in Irssi SILC Client.
432 Added `responder' boolean argument to the functions
433 silc_client_add_private_message_key[_ske] to indicate when
434 the key is added as responder or initiator of the key
437 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
439 * Removed the silc_ske_check_version function and created
440 a SilcSKECheckVersion callback. Added also a function
441 silc_ske_set_callbacks that is now used to set all SKE
442 callbacks. The callback functions are not given to
443 the SKE functions anymore, but this function is used to
446 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
448 * Added `silc_version' argument to the silc_client_alloc
449 to define the version of the application for the library.
450 The library will use the version string to compare it
451 against the remote host's (usually a server) version
452 string. Affected file lib/silcclient/silcapi.h
454 * Added the KE protocol context to Key Agreement context
455 in client library so that we can abort the SKE if it
456 is in process when we get timeout. Affected file is
457 lib/silcclient/client_keyagr.c.
459 * Do not resolve the client ID forever if it returns in the
460 first time that such client does not exist. This was done
461 for example with private message. Affected file is
462 lib/silcclient/client_prvmsg.c.
464 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
466 * Do not add regex.h for WIN32. The affected file
467 includes/silcincludes.h.
469 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
470 not work yet 100%. It generates the DLL's automatically
471 when compiling with --with-win32 under cygwin.
473 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
475 * lib/contrib/regex.c is not compiled on WIN32.
477 * Added silc_net_get_socket_opt function to the
478 lib/silcutil/silcnet.h.
480 * Added includes/silcwin32.h for WIN32 specific includes
483 * Do not use ptime structure or any of the posix process
484 functions on WIN32 in lib/silccrypt/silrng.c.
486 * Added silc_gettimeofday to provide generic function
487 for struct timeval on all platforms. Added the function
488 to lib/silcutil/silcutil.h.
490 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
492 * Moved the lib/silccore/silcsockconn.[ch] to the utility
493 library as they clearly belong there. As a plus side we
494 can make the actual socket connection routines platform
497 Added also new generic function silc_socket_read and
498 silc_socket_write (that used to be silc_packet_[read/write].
499 The implementation of these are platform specific.
501 * Added WIN32 specific routines of silc_socket_[read/write]
502 to lib/silcutil/win32/silcwin32sockconn.c.
504 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
506 * Added preliminary support for native WIN32 compilation under
507 cygwin (using the -mno-cygwin option for GCC) to the
508 ./configure.in.pre. The --with-win32 now prepares the
509 compilation for native WIN32.
511 * Rewrote the SILC Scheduler interface in the file
512 lib/silcutil/silcschedule.h. The scheduler is now context
513 based and does not have anymore any global static scheduler.
514 Moved the Unix scheduler to the lib/silcutil/unix/ directory
515 and created lib/silcutil/win32 directory for WIN32 based
518 * Added Unix specific network routines to the
519 lib/silcutil/unix/silcunixnet.c and the old
520 lib/silcutil/silcnet.c includes now only generic routines.
522 Added WIN32 specific network routines to the
523 lib/silcutil/win32/silcwin32net.c.
525 * Added Unix specific utility functions from the
526 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
528 * Added WIN32 SILC Scheduler to the file
529 lib/silcutil/win32/silcwin32schedule.c. The code is of course
532 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
534 * Do not handle JOIN notify in the server if the target client
535 is not registered (idata->registered == FALSE). The affected
536 file is silcd/packet_receive.c.
538 * Update the nickrec->founder in event_cumode in the Irssi SILC
539 client. Affected file irssi/src/silc/core/silc-channels.c.
541 * Fixed the CUMODE_CHANGE notify handling in the server when
542 server and router are announcing their clients on channels.
543 Now the mode changes are saved and notified correctly. The
544 affected file is /silcd/packet_receive.c.
546 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
547 They really did not replace the cache entry in the ID Cache.
548 Now they do that. Affected file silcd/idlist.c.
550 * Fixed the KICK notify handling in the Irssi SILC client to
551 update the channel records so that the kicked client does not
552 appear to be on the channel. The affected file is
553 irssi/src/silc/core/silc-channels.c.
555 * Always update the conn->current_channel when executing command
556 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
558 * Fixed the KILL notify handling in Irssi SILC client to remove
559 the killed client on all channels.
561 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Fixed the silc_parse_command_line to remove extra spaces
564 from the start and end of the arguments. Affected file is
565 lib/silcutil/silcutil.c.
567 * Cancel and free any active protocol in the function
568 silc_server_close_connection. Affected file silcd/server.c.
570 * Cancel and free any active protocol in the function
571 silc_client_close_connction. Affected file is
572 lib/silcclient/client.c.
574 * Do not execute the KILL command for clients that are in
575 history (ie. they are not in the network). Affected file is
578 * Fixed KILL notify handling, client does not crash anymore.
579 Affected file irssi/src/silc/core/silc-channels.c.
581 * Reduced the default packet buffer size from 2048 to 1024 in
582 lib/silccore/silcpacket.c.
584 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
585 counter to the SKE context that is incresed when the SKE library
586 performs async operation outside the library. If the outside
587 process frees the SKE context and FREED status will be set
588 and the library will detect after the sync operation that the
589 libary is freed. The affected files are
590 lib/silcske/silcske[_status].[ch].
592 * Resolve the client entry information in the function
593 silc_client_channel_message to assure that NULL pointer is not
594 passed as client entry to the application. */
596 * Fixed the task timeout calculation to assure that there is
597 never negative timeouts. The affected file is
598 lib/silcutil/silcschedule.c.
600 * Fixed the channel user mode notification sending in server.
601 It was sent point-to-point to the router (or to server by router)
602 but it needs to be destined to a channel. The routines now
603 supports sending the channel user mode notifys to the channels
604 when announcing clients and channels. Affected files are
605 silcd/server.c and silcd/packet_receive.c.
607 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
608 It did not actually replace the old channel entry in the cache.
609 Affected file lib/silcclient/client_notify.c.
611 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
613 * Fixed a possible crash in silc_packet_send_prepare. It now
614 assures always that there is enough space in the buffer and
615 at the tail area of the buffer (for MAC).
617 Fixed the inbound buffer reallocation in silc_packet_read.
618 It was old code and did not handle the reallocation correctly.
621 The affected file is lib/silccore/silcpacket.c.
623 * Fixed buffer overflow in silc_parse_nickname in the file
624 lib/silcutil/silcutil.c.
626 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * make install generates new server keys only if there is not
631 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
634 Added check that if the NOREPLY is set then we will not send
635 the away message. This avoids infinite loop of away messages
636 if both clients are away. The affected file is
637 lib/silcclient/client_prvmsg.c.
639 * Fixed client crash if /NICK was given without arguments.
640 Affected file lib/silcclient/command.c.
642 * Server does not send the invite list in INVITE command back
643 to the client if the list was not altered. Added this notion
644 to the protocol spec as well. Affected file silcd/command.c.
646 Fixed possible crash in INVITE command by checking the
647 value of silc_server_get_client_route command.
649 * Fixed the INVITE notify type handling. The arguments are now
650 taken in correct order and client does not crash. The affected
651 file is irssi/src/silc/core/silc-channels.c.
653 Removed the "Inviting xxx to channel" message from the
654 client library away and let the application handle it.
655 Affected file lib/silcclient/command.c. Added that message
656 to Irssi SILC client's message formats.
658 * Fixed CMODE command crash in client. It now checks the
659 amount of arguments correctly and does not crash. The affected
660 file is lib/silcclient/command.c.
662 * Do not create new channel automatically in silc_channels_join
663 but check whether the channel by that name already exists.
664 Affected file irssi/silc/core/silc-channels.c.
666 * Do not send the SERVER_SIGNOFF to router if the disconnected
667 entity was the router. Affected file silcd/server.c.
669 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
670 SILC client as it was missing from there.
672 Added the handling of the KICK notify to the Irssi SILC client
673 as it was missing. Added "you have been kicked" message to
674 Irssi SILC client's message modules formats.
676 Added the handing of the KILL notify to the Irssi SILC client
677 as it was missing. Added the kill message module formats
680 The affected file is irssi/src/silc/core/silc-channels.c.
682 * The router did not save the channel mode the server announced.
683 Affected file silcd/packet_receive.c.
685 * Fixed a possible crash in INFO command in server. If the
686 server did not provide the server info it crashed. Affected
687 file silcd/command.c.
689 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Fixed the GETKEY command in the server to check also the
692 global list. Otherwise the GETKEY would not work correctly
693 in normal SILC server. Affected file silcd/command.c.
695 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
697 * Fixed GETKEY crash, it crashed if the command did not succseed.
699 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
702 is now real and not just an macro interface to GMP.
704 Removed the entire GMP from the source tree and imported new
705 NSS MPI library instead. Reason for removing GMP is that it is
706 extremely large and compiles extremely slow. The NSS MPI
707 is only a few files and compiles in less than 10 seconds.
708 The speed is also about the same as GMP. The MPI is imported
711 If the system has GMP installed we will still use the GMP.
712 If it is not then the NSS MPI will be compiled.
714 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Merged a long nickname (127 characters long) crash bugfix from
717 Irssi CVS tree. Affected file irssi/src/core/misc.c.
719 * Merged a freed memory reference bugfix from Irssi CVS tree.
720 Affected file irssi/src/core/commands.c.
722 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Added the server's public key sving and verification to the
725 server when performing the SKE. This was missing and the
726 remote server's (or router's) public key was accepted without
727 checking whether we have it previously or trust it at all.
728 Affected file silcd/protocol.c.
730 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Check in the silc_server_timeout_remote if protocol is active
733 and make sure that the protocol's final callback is called so
734 that all memory if freed. Affected file silcd/server.c.
736 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * silc_server_whois_send_reply crashed the server if the nickname
739 was 127 characters long. Affected file silcd/command.c.
741 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Added sanity check to the silc_server_new_client. If the hostname
744 is provided inside username then check that the provided hostname
745 really is the same as the resolved one. If the hostname was not
746 resolved then check it from the public key. Affected file is
747 silcd/packet_receive.c.
749 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
750 if the server disconnected us and the connection is not valid
751 anymore. Affected file irssi/src/silc/core/silc-channels.c.
753 * Moved the silc_client_[chmode|chumode|chumode_char] away from
754 the library to the lib/silcutil/silcutil.[ch].
756 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Close log file after open. Affected file
759 lib/silcutil/silclog.c.
761 * Check whether sock == NULL in silc_client_send_packet and return
762 if it is. Affected file lib/silcclient/silcclient.c.
764 * Check rec->entry == NULL in the Irssi SILC Client before
765 sending the channel message. Affecte file is
766 irssi/src/silc/core/silc-servers.c.
768 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Merged a splitted window bugfix from Irssi CVS tree. The
771 affected file is irssi/src/fe-text/textbuffer-view.c.
773 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
774 It did not print nickname.
776 * Improved the distributions system a bit.
778 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
781 irssi/src/fe-text/gui-window.c.
783 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
784 to in-active server. The affected file is
785 irssi/src/silc/core/client_ops.c.
787 * Resolve the client in USERS command reply if the entry does
788 not have username resolved. The affected file is
789 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
790 command to WHOIS command to really resolve stuff. The USERS
791 is not used any more in any critical section so WHOIS can
792 be used even though it might be slower than IDENTIFY.
794 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
797 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Changed the protocol API a bit more consistent in the
800 lib/silccore/silcprotocol.[ch].
802 * Changed the following headers to ROBODoc format:
804 lib/silccore/silcpayload.h
805 lib/silccore/silcprotocol.h
806 lib/silccore/silcsockconn.h
808 All core library headers are now formatted.
810 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Fixed a bug in Irssi SILC client; do not show that you are
813 server/router operator if you really are not. Affected file is
814 irssi/src/silc/core/client_ops.c.
816 * Renamed silc_command_free_payload to silc_command_payload_free.
817 Affected file lib/silccore/silccommand.h
819 * Added silcmath.h to include the prototoypes of various routines
820 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
823 * Changed the following headers to ROBODoc format:
825 lib/silccore/silcchannel.h
826 lib/silccore/silccommand.h
827 lib/silccore/silcid.h
828 lib/silccore/silcidcache.h
829 lib/silccore/silcmode.h
830 lib/silccore/silcnotify.h
831 lib/silccore/silcpacket.h
832 lib/silcmath/silcmath.h
834 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added checking to the server code not to start the server if
837 ciphers and stuff are not configured properly. Affected files
838 silcd/serverconfig.[h] and silcd/server.c.
840 * Changed the layout of the header files of the public interfaces
841 in the SILC libraries. The new layout supports ROBODoc
842 documentation tool (and some others) so that it is easy to create
843 a library reference manual. All the other headers and source
844 code must still follow the CodingStyle document. Also source
845 code must not include these ROBODoc stuffs, only the headers.
846 Furthermore, all public interface headers must now be named
847 by using `silc' prefix, example: silcapi.h, silccipher.h.
848 Some files were renamed due to this. All the other headers
849 must not be used as public interfaces. I will update the
850 CodingStyle document later. Changed following headers, so far:
852 lib/silcclient/silcapi.h
853 lib/silccore/silcauth.h
854 lib/silccore/silcprivate.h
855 lib/silccrypt/silcdh.h
857 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Removed silc_client_packet_send_flush from the client library
862 as it is not needed. Affected file lib/silcclient/client.[ch].
864 * Added printing of message of unresolved authentication method
865 to the Irssi SILC client. Added it to the module formats.
866 Removed the same message from the client library.
868 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Added new distribution feature, DISTLABEL. Every distribution
871 can define own preprocessor label that can be used in the
872 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
873 file distributions, acconfig.h.pre and prepare.
875 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Added Makefile.defines_int to include the actual definitions
878 for Makefile.defines.in. Tested the new distribution system,
879 created distributions and tested installation.
881 * Added AWAY message printing to the Irssi SILC client. Added
882 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
884 * Added SCONNECT command to call the SILC's CONNECT command.
885 Cannot use CONNECT directly since Irssi uses that internally.
886 Affected file irssi/src/silc/core/silc-servers.c.
888 Added ACTION local command. It is same as ME command but takes
889 the channel as mandatory argument.
891 Rewrote some of the Irssi's help files to suite for SILC
894 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Added Makefile.defines[.in] that should for now on be included
897 in all Makefile.am file in the source tree. That file includes
898 all common compilation definitions for SILC source tree.
900 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
902 * Minor changes to the ./prepare script to change the package
903 name according the distribution name to the configure.in.
905 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Created new distribution system. Added file `distributions'
908 that defines all the distributions that can be created out of
909 the SILC source tree. The ./prepare script now reads that
910 file to determine how to prepare the distributions. The
911 first argument to the ./prepare is the name of the distribution
912 and second is the version of the distribution. If given
913 without arguments it creates the default (toolkit) distribution
914 with the default version (defined in ./prepare).
916 All Makefile.am files that are subject to the distributions
917 are now named as Makefile.am.pre. These are ./Makefile.am
918 and lib/Makefile.am. Others may be changed later.
920 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added invite list, ban list, some key management and connection
923 error message printing to module formats in the Irssi SILC client.
925 * Added new silc_client_set_away_message to set the away message
926 that is back to the person who sent private message. The
927 affected file lib/silcclient/silcapi.h and the
928 lib/silcclient/client_prvmsg.c.
930 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Fixed the private message sending in the Irssi SILC client,
933 added local command KEY to the Irssi SILC client.
935 Added key management and key agreement message formats to the
936 irssi/src/fe-common/silc/module-formats.[ch].
938 Added USERS (alias WHO) printing, server/router operator
939 indication and LIST command printing to the module formats.
941 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Fixed channel joining notify handling, cumode notify handling
944 from Irssi SILC client.
946 * Added SILC specific module-formats to the Irssi SILC client so
947 that SILC specific message hilighting, colors etc is possible.
948 Affected file irssi/src/fe-common/silc/module-formats.[ch].
950 Added channel mode, channel user mode, actions, notices,
951 whois and whowas printing to the the module-formats.c.
953 * Fixed a bug in channel deletion in the server. The channel
954 is not left to the cache even if the channel founder auth mode
955 is set when there are no users anymore on the channel. Affected
958 * The silc_net_localhost now resolves the entire hostname including
959 the domain name. Affected file lib/silcutil/silcnet.c.
961 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Changed the ask_passphrase client operation to be ascynchronous.
964 It has now a completion callback and a context that the
965 application must call after it has got the passphrase from
966 the user. Affected files lib/silcclient/silcapi.h,
967 lib/silcclient/protocol.c, lib/silcclient/command.c and
970 Added SilcAskPassphrase callback that the application calls
971 to deliver the passphrase to the library.
973 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
974 The public key verification and especially a certificate
975 verification is asynchronous procedure.
977 Added new SILC_SKE_STATUS_PENDING status to indicate the
978 request is pending and a callback will be called to finalize
981 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
982 indicate that remote end did not send its public key (or
983 certificate), even though we require it. Added check for this
984 condition in the SKE. This was a security bug, now fixed.
986 Defined new SilcSKEVerifyCbCompletion callback that is called
987 when the verification process is completed.
989 The affected files lib/silcske/silcske_status.h and
990 lib/silcske/silcske.[ch].
992 * Changed the verify_public_key client operation to be async
993 as well. Defined SilcVerifyPublicKey callback that is used to
994 indicate the success of the public key verification process.
996 Changed the server and client to use the new async client
999 * Changed the Irssi SILC client's internal scheduler to be called
1000 twice as many times as it used to be. As a result the client
1001 should be a bit faster now. Affected file is
1002 irssi/src/silc/core/silc-core.c.
1004 * Added support to Irssi SILC client of asynchronous public key
1005 verification and passphrase inquiry. Affected file is
1006 irssi/src/silc/core/silc-core.c.
1008 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Do not say "You have left channel %s" in client library.
1011 Moved it to the application. Affected files are
1012 lib/silcclient/command.c and silc/client_ops.c.
1014 * Fixed silc_client_get_clients. Command context was not
1015 duplicated and was freed memory in the callback. Affected
1016 file lib/silcclient/idlist.c.
1018 * Do not say "you are now talking..." on JOIN command in the
1019 client library. The appliation must handle it.
1021 * Do not say ".. changed topic to" in command reply in the
1022 client libary. The application must handle it.
1024 * Fixed TOPIC command sending in the client library.
1026 * Fixed a memory leak in silc_client_command_free in the file
1027 lib/silcclient/command.c.
1029 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Imported a modified version of Irssi client to the source tree.
1032 The Irssi will be used to create a new client called
1033 Irssi SILC. Imported to irssi/.
1035 Added silc_core_init_finish function to the Irssi. Affected
1036 file irssi/configure.in.
1038 A lot changes in the Makefile.ams around the irssi tree.
1040 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Do not rehash if the new size is same as the old size of the
1043 hash table, in the silc_hash_table_rehash*. The affected file
1044 lib/silcutil/silchashtable.c.
1046 * Replaced hash_table_del_by_context calls from the server
1047 (when channel->user_list and client->channels) to the
1048 hash_table_del as it is sufficient and faster.
1050 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Added silc_hash_table_list, silc_hash_table_get and the
1053 SilcHashTableList structure to provide an alternative way to
1054 traverse the hash table. The affected files are
1055 lib/silcutil/silchashtable.[ch].
1057 * Changed the server's idlist routines to use the hash table
1058 routines to optimize the code.
1060 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1062 * Replaced the client entry's `channel' list and channel entry's
1063 `user_list' list to hash tables for optimized lookup. Changed
1064 the code to use the hash table interface around the code.
1065 Affected file lib/silcd/idlist.[ch].
1067 * Added `auto_rehash' boolean argument to the function
1068 silc_hash_table_alloc to indicate whether the hash table should
1069 auto-rehash when it thinks is appropriate time. It will
1070 increase the hash table size if the there is twice as much
1071 entries in the table than the size of the table, and will
1072 decrease the size if there are twice as less entries than
1073 the size of the table.
1075 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1079 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * silc_idcache_purge_by_context deletes the entry now by context
1082 as it is supposed to do. Affected file lib/silccore/idcache.c.
1084 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1085 client is not anymore valid (WHOWAS givens the info) and not
1086 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1088 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Removed the `data' and `data_len' arguments from the ID Cache
1091 interfaces and added `name' argument. ID Cache does not handle
1092 anymore the binary data only a names associated with given ID.
1094 * When hashing a Client ID with silc_hash_id the entire ID is
1095 not hashed anymore, instead only the hash of the Client ID is
1096 hashed. This way we can access the Client ID from the cache
1097 with Client ID but with the hash of the ID (which is a hash of
1098 the nickname) as well without any difference in performance.
1100 Added also silc_idcache_find_by_id_one_ext to do one on one
1101 searching when we have the actual ID. Added also function
1102 silc_hash_client_id_compare. The affected files are
1103 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1105 * When hashing the name associated with a ID it is always done
1106 in lowercase. This way we can access the cache without worrying
1107 about case-sensitivity, even though, for example nicknames are
1110 * Fixed a bug in server with channel message sending. It put
1111 wrong ID type as destination ID. The affected file
1112 silcd/packet_send.c.
1114 * silc_idcache_del_by_context now deletes from all hash tables
1115 by context. Affected file lib/silccore/idcache.c.
1117 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1119 * Changed the client library to use the new ID Cache interface.
1120 Changes around the source tree.
1122 * Added silc_hash_table_rehash_ext to rehash with specific
1123 hash function. Affected file lib/silcutil/silchashtable.[ch].
1125 * Added silc_hash_string_compare to compare two strings in the
1126 hash table. Affected file lib/silcutil/silcutil.[ch].
1128 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1130 * Added new function silc_idcache_del_by_context into the
1131 lib/silccore/idcache.[ch].
1133 * Changed the server's ID list routines to use the new ID Cache
1134 interface. Changes around the source tree.
1136 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * Added silc_hash_table_del[_by_context]_ext functions in to the
1139 lib/silcutil/silchashtable.[ch].
1141 Removed silc_hash_table_find_all* routines and added new
1142 silc_hash_table_find_foreach to replace them.
1144 Added silc_hash_table_replace_ext function as extended
1145 replacing function. Separated the simple hash table interface
1146 from the extended hash table interface in the file
1147 lib/silcutil/silchashtable.h.
1149 * Fixed minor bugs and changed it to use some of the new
1150 hash table functions in lib/silccore/idcache.c
1152 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added new function silc_hash_table_find_all to return all keys
1155 in the hash table by the specified key. As the hash table is
1156 collision resistant it also makes it possible to have several
1157 duplicate keys in the hash table. This function may be used to
1158 find all of the keys from the hash.
1160 Added user_context arguments to the SilcHashFunction,
1161 SilcHashCompare and SilcHashDestructor to deliver user specified
1164 Added new fuctions silc_hash_table_find[_all]_ext to do
1165 extended lookup with specified hash and compare functions and
1166 specified user contexts.
1168 Added new function silc_hash_table_add_ext to add the key
1169 with specified hash function and user context.
1171 Added new function silc_hash_table_foreach to traverse all
1172 entrys in the hash table. Added SilcHashForeach callback
1175 Added new function silc_hash_table_del_by_context to delete
1176 the entry only if the context associated with the key matches.
1178 Affected files are lib/silcutil/silchashtable.[ch].
1180 * Removed silc_hash_[server/client/channel]_id and added just
1181 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1182 silc_hash_id_compare to compare two ID's using as the hash table
1183 comparison function. Added also silc_hash_data to hash
1184 binary data and silc_hash_data_compare to compare it.
1186 * Removed silc_idlist_find_client_by_hash as it is not needed
1187 anymore. Affected file silcd/idlist.[ch].
1189 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1190 to use internally the SilcHashTable. The new ID Cache is a lot
1191 faster than the old one. Some of the ID Cache interface was also
1192 rewritten and obsolete and stupid functions were removed.
1194 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Added entry_count field to the SilcHashTable to keep the number
1197 of the entries in the table. Implemented the function
1198 silc_hash_table_rehash. Added new function
1199 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1201 Fixed a minor bug in silc_hash_table_free.
1203 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1204 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1205 into the lib/silcutil/silcutil.[ch].
1207 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Implemented a collision resistant hash table into the
1210 lib/silcutil/silchashtable[ch]. See the header and the source
1211 for the SilcHashTable API.
1213 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Merged dotconf version 1.0.2 into lib/dotconf.
1217 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Do not compile anything in lib/silcsim/* if the SIM support
1220 is not enabled. The tree should now compile without problems
1223 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Compiled the SILC under cygwin. Compiled and tested briefly
1226 without problems. More tests needed. The SIMs didn't compile
1229 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1231 * Fixed possible crash in silc_get_username in the
1232 lib/silcutil/silcutil.c.
1234 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Fixed a va_arg in silc/client_ops.c.
1238 * Oops, RC5 routines were named AES and caused some problems
1239 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1241 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Added new SilcIDIP structure into the lib/silccore/id.h and
1244 replaced the old `ip' fields from all SILC ID's to that type.
1245 This is a step towards IPv6 support.
1247 The silc_id_get_len takes now the ID as an extra argument.
1248 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1249 both IPv4 and IPv6 based ID's.
1251 The affected files are lib/silccore/id.[ch] and other files
1252 around the tree using these routines.
1254 * Removed the ID length arguments in server from various
1255 silc_server_send_notify_* routines -> they are not needed
1258 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * Fixed memory leak in silc_encode_pem_file in the file
1261 lib/silcutil/silcutil.c.
1263 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1265 * Check minor version as well in the SKE. Affected files are
1266 silcd/protocol.c and lib/silcclient/protocol.c.
1268 * Added --identifier option to the server so that an identifier
1269 can be when creating the public key for the server. Affected
1270 file is silcd/silcd.c.
1272 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1273 lib/silccrypt/silcpkcs.c.
1275 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Register default ciphers and stuff when using -C option with
1278 the server. Affected file sildc/silcd.c.
1280 * Put back the servers public key filename format, it is better
1281 than the new one. For now, the client keys are saved with the
1282 new filename format. The affected file silc/client_ops.c.
1284 * Implemented the Cipher API for the rest of the ciphers that
1285 did not implement it or implemented it the wrong way.
1287 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Register default ciphers and stuff when using the -S option
1290 in the client. Affected file silc/silc.c. Same also when
1291 creating new key pair with -C option.
1293 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1295 * Fixed the silc_verify_public_key client operation function to
1296 save the public keys differently. The fingerprint is now
1297 used as filename and not the hostname. This way also the
1298 client keys are saved uniquely and not with hostnames. The
1299 affected file is silc/client_ops.c.
1301 * Trimmed the silc_hash_fingerprint function to remove extra
1302 whitespaces from the end of the fingerprint. The affected
1303 file is lib/silccrypt/silchash.c.
1307 * Added silc_cipher_register_default function to register all
1308 default ciphers. It can be used when configuration files
1309 does not exist and the application does not want any specific
1310 ciphers in any specific order.
1312 The SilcDList is now used as silc_cipher_list dynamically
1313 allocated cipher list. Removed the static list all together
1314 and now all ciphers must be allocated to the dynamic list.
1315 The silc_cipher_alloc routine was changed to check only the
1318 All silc_cipher_* routines that used to return int returns
1321 The affected files lib/silccrypt/silccrypt.[ch].
1323 * The same thing was done to silc_hash_* as for silc_cipher_*
1324 routines. Affected files lib/silccrypt/silchash.[ch].
1326 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1327 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1328 Added also silc_pkcs_[un]register[_default] functions.
1329 Removed the data_context from the PKCS API.
1331 * Added silc_hmac_register_default function to register default
1332 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1333 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1334 to unregister all hmacs at once.
1336 * Register the default ciphers, hash functions, PKCSs and HMACs
1337 if client's configuration file does not exist. The affected
1340 * The client did not load the hash functions from the SIM
1341 modules at all. Added support for this. Affected file is
1342 silc/clientconfig.c.
1344 * When decoding public key with silc_pkcs_public_key_decode, check
1345 the supported algorithm only if PKCS are registered. Affected
1346 file lib/silccrypt/silcpkcs.c. The same was done with the
1347 silc_pkcs_private_key_decode.
1349 * Fixed the SILC List routines to keep the list always in order.
1350 It used to change the list's order when traversing the list but
1351 not it preserves the order. Affected file lib/trq/silclist.h.
1353 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Added the client library to use the SilcSocketConnection's
1356 reference counter (by silc_socket_dup) to prevent the bug that
1357 the socket object may be freed underneath async operation.
1359 * The name resolv library checking fixes in the configure.in.pre.
1362 * Created new version of the protocol drafts for future
1363 development. The -03 drafts are the ones that will be changed
1364 in the trunk now and the -02 will remain as they are.
1366 * Send list of CUMODE notifys to the router when announcing
1367 the channel users to the router. Affected file silcd/server.c.
1368 If the router receiving channel founder CUMODE for a channel
1369 that already has channel founder it will send CUMODE notify
1370 to the sender to remove the channel founder rights from the
1371 announced client. Affected file silcd/packet_receive.c.
1373 * The CUMODE notify may now use Server ID as well as the entity
1374 who changes the mode. Updated protocool specs.
1376 * Updated INSTALL and README files.
1378 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * New web pages in the http://silc.pspt.fi. The pages was
1385 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * Implemented the [DenyConnectin] config section in the server.
1388 Added silc_server_config_denied_conn to check whether incoming
1389 connection is denied. Affected file silcd/serverconfig.[ch].
1391 * Do not check the ports when checking the incoming configuration
1392 data if the port is 0, meaning any. Affected file is
1393 silcd/serverconfig.c.
1395 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Fixed buffer overflow in silc_string_compare in the file
1398 lib/silcutil/silcutil.c.
1400 * Fixed double free in silc_server_command_leave in the file
1403 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Fixed the version checking in the server. Affected file is
1408 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1410 * Fixed the configuration data fetching when accepting new
1411 connections in the server. Affected file silcd/server.c.
1413 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Added `sender_entry' argument to the function
1416 silc_server_packet_relay_to_channel so that we can check
1417 whether some destination actually belongs to the same route
1418 the sender belongs (ie, we must not resend the packet to the
1419 sender). Affected file silcd/packet_send.[ch].
1421 * Added `servername' field to the SilcClientEntry in the server
1422 to hold the name of the server where client is from. Affected
1423 file is silcd/idlist.h.
1425 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1427 * Moved the channel message encrypting in the router betwen
1428 router connections from silc_server_channel_message to the
1429 silc_server_packet_relay_to_channel since we want to check
1430 whether we have anybody channel before encrypting anything.
1431 Affected files silcd/packet_[receive/send].c.
1433 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Fixed the [AdminConnection] server config section to support
1436 multiple entries. Affected file silcd/serverconfig.c.
1438 * Added support into the server to check the validity of the
1439 incoming connection before executing any KE or authentication
1442 * The connection configuration is now saved to the KE and
1443 connection auth protocol contexts and not fetched anymore in
1444 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1446 * The local hosts listenning address and port is also resolved
1447 now when starting the server. We want to have the socket object
1448 to include the real address and port for the listener. Added
1449 new function silc_net_check_local_by_sock into the files
1450 lib/silcutil/silcnet.[ch].
1452 * Fixed a broadcast bug in server -> do not broadcast if we
1455 * Fixed a routing bug. Do not route broadcast packets ever.
1456 Broadcast packets must be processed always and not routed since
1457 they may be destined to some other host than yourself and thus
1458 would get routed without no good reason. Affected file is
1461 * Added function silc_server_config_is_primary_route to check
1462 whether primary router connection has been configured (a router
1463 configuration that we are initiating). If there is not, we
1464 will assume that there is only two routers in the SILC network
1465 and we will use the incoming router connection as our primary
1466 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1468 * Changed the order of the broadcasting. Broadcast _after_ the
1469 packet has been processed not before. Affected file is
1472 * Fixed a [ClientConnection] parsing bug. The port was never
1473 parsed correctly thus resulting to port 0. Affected file
1474 silcd/serverconfig.c.
1476 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1477 argument and did not set the broadcast packet flag. Affected
1478 file silcd/packet_send.c. Fixed same bug in the function
1479 silc_server_send_notify as well.
1481 * If we receive NEW_ID packet for our own ID in the server, ignore
1484 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Removed the nickname from the Private Message Payload.
1489 Updated the code and the protocol specs.
1491 * Updated protocol specs for submitting to the IETF.
1493 * Tweaked the Random Number Generator a bit. Affected file
1494 lib/silccrypt/silcrng.c. Exported a new function
1495 silc_rng_[global]_add_noise which can be used to add more
1498 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Do not parse packets with different timeout when protocol
1501 is active -> may cause problem with rekey. Affected file
1504 * When server receives signoff notify it must not create
1505 new channel key if the client is on any channels since the
1506 sender of the signoff notify will create it.
1508 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Added printing of error messages during SKE protocol from the
1511 failure packet sent by server during SKE. Affected file
1514 * Removed the client's failure_callback handling with timeout
1515 and handle it immediately when received.
1517 * The SKE library returned wrong type in SUCCESS and FAILURE
1518 packets. They must be 32 bit MSB not 16 bit MSB.
1520 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1522 * Ok, rewrote the logic of the re-key and now it seems to work.
1523 I tested it on high traffic with frequent re-keys without
1524 problems. Added hmac_receive (and renamed hmac to hmac_send)
1525 in SilcClientConnection in lib/silcclient/client.h and
1526 in SilcIDListData in silcd/idlist.h. Also, removed the
1527 SilcPacketParserContext's cipher and hmac fields as they are
1528 not needed anymore and actually caused some problems when
1529 the ciphers and hmac's changed underneath the packet parser.
1531 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * If re-key protocol is active then process the incoming packets
1534 synchronously since we must assure that icoming packets encrypted
1535 with the old key is processed before the new keys is set to
1536 use. This is true other packets than for REKEY packets.
1537 Affected file silcd/server.c. The same was done to client library
1538 as well, affected file lib/silcclient/client.c.
1540 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Fixed bug in client and server to accept the force send if
1543 the packet is send from silc_[server/client]_packet_process
1544 function. Otherwise the packets are never delivered, oops.
1546 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1548 * Disable force sending of packets when REKEY protocol is active.
1549 We must assure that no packet is sent directly when rekey is
1550 performed. All packets must be sent through packet queue.
1551 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1552 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1553 function is silc_[server/client]_packet_send_real to check
1556 * Replaced the SIM paths from example config files to
1557 /usr/local/modules. Also, make install creates now
1558 /usr/local/silc/logs directory to hold all the SILC server
1561 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Made the configure.in.pre work on Solaris. Patch by salo.
1565 * Made all ciphers compatible with non-x86 machines. Defined
1566 CBC mode macros into lib/silccrypt/ciphers_def.h.
1568 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Fixed the make install.
1572 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * When MAC computation fails the silc_packet_decrypt returned 0
1575 even though it was supposed to return -1. Fixed this. The
1576 affected file is lib/silccore/silcpacket.c.
1578 * Do not replace the config files in /etc/silc (in make install)
1579 if they already exist. Affected file ./Makefile.am.
1581 * Do not send re-key packets immediately but through packet queue.
1582 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1584 * Changed silc_net_check_host_by_sock to return FALSE if the
1585 IP/DNS could not be resolved. Though, it returns the IP address
1586 now even if it could not resolve it (but returns also FALSE).
1587 Affected file lib/silcutil/silcnet.[ch].
1589 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1591 * Added silc_pkcs_decode_identifier to decode the public key's
1592 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1593 Added also silc_pkcs_free_identifier. Added also new context
1594 SilcPublicKeyIdentifier.
1596 * Added -S option to the silc client. It is used to dump the
1597 contents of the specified public key file.
1599 * Changed the PKCS api to return the public key length when
1600 setting the public key.
1602 * Fixed a fatal bug in the public and private key file loading.
1603 Affected file lib/silccrypt/silcpkcs.c.
1605 * Execute the packet parsing for client with zero (0) timeout
1606 if the protocol is active. Affected file silcd/server.c.
1608 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Made the key generation options to the silcd program. Added
1611 -C option, equivalent to client's option.
1613 * Added new [ServerKeys] config section to the server. It
1614 configures the server's public and private key.
1616 * Defined generic Public Key Payload into the protocol
1617 specification to send specific type of public keys and
1620 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1621 public key or certificate.
1623 * Implemented the GETKEY command to the server and to the
1624 client library and on user interface.

1632 * Added SilcServerRekey context into silcd/idlist.h.
1634 * Added the PFS support as defined in the specification to the
1635 SKE protocol. Affected files lib/silcske/*.c.
1637 * Added `ske_group' field to the SilcServerRekey context to hold
1638 the number of the SKE group that is used with PFS in re-key.
1639 Affected file silcd/idlist.h.
1641 * Added PFS re-key support to the server. Affected file is
1644 * Added silc_protocol_cancel to cancel execution of the next
1645 state of the protocol. Affected file is
1646 lib/silccore/silcprotocol.[ch].
1648 * Added the re-key support with and without PFS to the client
1649 library. Re-key is performed once in an hour, by default.
1651 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1652 Added silc_client_rekey_callback and silc_client_rekey_final.
1653 Affected files are lib/silcclient/protocol.[ch] and
1654 lib/silcclient/client.[ch].
1656 * Removed the `hmac_key' and `hmac_key_len' fields from the
1657 SilcClientConnection structure; not needed. Affected file is
1658 lib/silcclient/client.h.
1662 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Do not ask whether user wants to use the negotiated private key
1665 for private messages, just use it. Affected file is
1666 silc/local_command.c.
1668 * Added `send_enc_key' and `enc_key_len' fields to the
1669 SilcIDListData structure since they are needed in the re-key
1670 phase. Affected file is silcd/idlist.[ch].
1672 * Implemented the simple re-key protocol into the server.
1673 Affected files silcd/server.c and silcd/protocol.[ch]. The
1674 re-key will be performed once in an hour, by default.
1676 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1677 Added silc_server_rekey, silc_server_rekey_callback and
1678 silc_server_rekey_final.
1680 * Removed Tunneled flag from the protocol. Updated the code
1681 and the specifications.
1683 * Adde `pfs' field to the SilcIDListData to indicate whether
1684 the PFS is to be performed in the re-key. Affected file is
1687 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1690 int64 of at least the xintXX size. If void * is less that 4
1691 bytes uint32 * will be used. Defined bool as boolean.
1693 * Changed _ALL_ unsigned long and unsigned int to uint32,
1694 unsgined short to uint16 in the source tree.
1696 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1697 not handle clients that has entry->data.registered == FALSE.
1698 They are not in the network anymore. Affected file is
1701 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * Implemented the sending of the SERVER_SIGNOFF notify in the
1704 server. Affected file is silcd/server.c.
1706 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1707 Added also silc_notify_payload_encode_args into the
1708 lib/silccore/silcnotify.[ch].
1710 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1711 Affected file silcd/packet_receive.c.
1713 * Implemented the SERVER_SIGNOFF notify handling in the client
1714 library. Affected file lib/silcclient/client_notify.c. Also,
1715 implemnted the printing of the SERVER_SIGNOFF info to the
1716 application. Affected file silc/client_ops.c.
1718 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1719 if the deleting was successful. Affected file silcd/idlist.[ch].
1721 * Added support for public key authentication in the connection
1722 authentication protocol in the client library. Affected file
1723 lib/silcclient/protocol.c.
1725 * Changed the server's silc_idlist_get_clients_by_* interface
1726 to support already allocated array so that new entries may be
1727 added to pre-allocated array. Affected file silcd/idlist.[ch].
1728 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1729 and command replies.
1731 * All command reply functions in the server now calls the
1732 pending command callback even if error occured. This way the
1733 error will be delivered to the client as well. Affected files
1734 silcd/command.c and silcd/command_reply.c.
1736 * Fixed INFO command to return local server's info if no server
1737 was provided. Affected file lib/silcclient/command.c.
1739 * Removed RESTART command for good. Updated the code and the
1742 * Rewrote parts of the task system. It is a bit simpler now.
1743 Removed unsued task priorities. The affected files are
1744 lib/silcutil/silctask.[ch].
1746 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1748 * Moved the USERS printing from the library to the application.
1749 Affected files lib/silcclient/command.c and silc/client_ops.c.
1751 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Added channel key re-key support. The re-key is perfomed
1756 only by the router and is done once in an hour. Added `rekey'
1757 field to the SilcChannelEntry in the server. Affected files
1758 silcd/server.c and silcd/idlist.h.
1760 * Added silc_task_unregister_by_context into the file
1761 lib/silcutil/silctask.[ch].
1763 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1765 * Added SILC_UMODE_GONE mode to indicate when the client is not
1766 present in the SILC network. Added also support to the local
1767 command AWAY that will set this mode. Added support of showing
1768 "xxx is gone" in WHOIS command. The USERS command shows the
1769 gone status as well.
1771 * Fixed setting server and router operator privileges in the
1772 server's UMODE command. Affected file silcd/command.c.
1774 * Merged the SKE KE1 and KE2 payloads into one payload. The
1775 new KE payload is equivalent to the old KE2 payload.
1777 Cleaned up the SKE Start Payload parsing. It now uses the
1778 simple buffer unformatting to do the parsing. A lot faster
1781 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1782 to the SKE that is used to indicate whether both of the SKE
1783 parties should perform authentication. By default only the
1784 responder performs authentication. By setting this flag also
1785 the initiator must do authentication. By default it is unset
1786 since in normal SKE case, client to server connection, only
1787 the responder should do authentication. When doing SKE between
1788 two clients both should perform authentication. Updated the
1789 code and the protocol specs.
1791 * A little fix to IDENTIFY command in the server. Search the
1792 client first by hash not nickname. Affected file is
1795 * Fixed the silc_client_close_connection to support closing
1796 the client to client connections wihtout deleting too much
1797 data. Affected file lib/silcclient/client.c.
1799 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1800 are received if protocol used to be active but is not anymore
1801 the application would crash due to NULL pointer dereference.
1802 Affected files silcd/server.c and lib/silcclient/client.c.
1804 * Added `hash' field to the SilcClientConnection to include
1805 the hash function negotiated in the SKE protocol.
1807 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1808 to set the channel founder authentication data. A client can
1809 claim the founder rights later by providing the authentication
1810 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1811 This way the channel founder can regain the channel founder
1812 privileges even it is left the channel. This works only on
1813 local server and the client must be connected to the same
1814 server to be able to regain the founder rights. Updated the
1815 protocol specs accordingly.
1817 Added support to the CMODE command in the client to set the
1818 founder auth data. Read the README to see how to set it.
1820 Added support to the CUMODE command to claim the founder
1821 rights. Read the README to see how to do it.
1823 Added support for the founder authentication to the Channel
1824 Entry in the server. Affected file silcd/idlist.h.
1826 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1827 server's CMODE command. Affected file silcd/command.c.
1829 * Added the following new functions into lib/silccore/silcauth.[ch]:
1830 silc_auth_get_method and silc_auth_get_data.
1832 * The server now saves the remote hosts public key to the
1833 SilcIDListData pointer. Affected file silcd/protocol.c.
1835 * The normal server now does not remove the channel entry from
1836 the cache if the founder authentication data is set. It used
1837 to remove it if the founder was the last one on the channel on
1838 the server and left the channel. The auth data is saved and
1839 if the channel is re-joined later the old entry is used with
1840 the old auth data. Affected files silcd/command_reply.c and
1843 * Removed the `pkcs' field from the SilcIDListData structure
1844 in the server; it is not used. Affected file silcd/idlist.h.
1846 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * Fixed packet processing on slow links. Partial packets were
1849 never re-processed because the incoming data buffer was cleared
1850 by the application. Application must not directly clear the
1851 sock->inbuf, the packet processing routines handle it. Fixed
1852 this in client library and in server.
1854 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Fixed the WHOIS and IDENTIFY send reply function to really
1857 check whether to send list or just one entry. Affected file
1860 * Cleaned up the LEAVE command's channel key distribution. The
1861 affected file silcd/command.c.
1863 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1864 can enforce the channel mode as well. In that case the ID
1865 includes the ID of the server. The code now enforces the
1866 mode change if the router have different mode than the server.
1868 * The notify client operation with CMODE_CHANGE notify can now
1869 return NULL client_entry pointer if the CMODE was not changed
1870 by client. Application must check for this.
1872 * Added <Server ID> argument to INFO command to support server
1873 info fetching by Server ID.
1875 * Added silc_server_announce_get_channel_users to get assembled
1876 packets of channel users of the specified channel. Affected
1877 file silcd/server.[ch].
1879 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1880 was freed underneath the ID Cache.
1882 * Re-announce clients when the server received CHANNEL_CHANGE
1883 notify from the router. Affected file silcd/packet_send.c.
1885 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1888 crashed since it did not handle the fact that there is no cipher
1889 called "3" and didn't check the error condition. Now fixed.
1891 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1892 flag. It can be used to send message requests.
1894 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Implemented the RESTART command in the client.
1898 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1899 notice type messages. Added notice printing to the user
1902 * The channel keys are not re-generated if the channel's mode
1903 is PRIVKEY, ie private key on the channel exists. Affected
1904 files silcd/server.c and silcd/command.c.
1906 * Fixed a little bug in channel message delivery when channel
1907 private keys are set in the server. Affected file is
1908 silcd/packet_send.c.
1910 * Changed the setting on channel->on_channel = TRUE from the
1911 silc_client_save_channel_key to the JOIN command reply. The
1912 key payload is not received if the private channel key is set.
1913 Affected file lib/silcclient/command_reply.c and the
1914 lib/silcclient/client_channel.c.
1916 * When the CMODE_CHANGE notify is sent and the channel private
1917 key mode is removed the channel key must be re-generated in
1918 other cells as well. Added this support for the router in the
1919 silcd/packet_receive.c.
1921 * Added new local command NOTICE to send notice message on
1922 channel. Affected file silc/local_command.[ch].
1924 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Added new local command ME to the client. It is used to send
1927 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1928 some action. Affected file silc/local_command.[ch].
1930 * Changed channel_message and private_message client operations
1931 to deliver the message flags to the application. Added also
1932 the `flags' arguments to the silc_client_send_channel_message
1933 and silc_client_send_private_message functions. Affected file
1936 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Redefined the Private Message Payload to support private message
1939 keys and to support the new private message flags. Updated
1940 the protocol specs. Flags makes it possible to have for example
1941 CTCP style messages.
1943 * Added new type SilcPrivateMessagePayload and defined an API
1944 for it in the lib/silcclient/silcprivate.[ch].
1946 * Tested private message private keys successfully. Tested the
1947 private message key set, unset and list commands with the new
1950 * Redefined the Channel Message Payload to include the channel
1951 message flags (equal with private message flags) to support
1952 for example CTCP style messages.
1954 * Defined some of the message (for channel and private message)
1955 flags. Updated the protocol specs and added the flags to the
1956 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1958 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Added SilcKeyAgreementStatus type to the key agreement routines
1961 to indicate the current status and error if one occured.
1962 The status types are defined in the lib/silcclient/silcapi.h.
1964 * Added new local command KEY that is used to set and unset private
1965 keys for channels, set and unset private keys for private messages
1966 with remote clients and to send key agreement requests and
1967 negotiate the key agreement protocol with remote client. The
1968 key agreement is supported only to negotiate private message keys,
1969 it currently cannot be used to negotiate private keys for channels,
1970 as it is not convenient for that purpose.
1972 * Fixed a minor pending callback setting bug in the function
1973 silc_client_get_client_by_id_resolve, now the function works.
1974 Affected file lib/silcclient/idlist.c.
1976 * Added function silc_net_get_local_port to get local bound
1977 port by socket. Added to lib/silcutil/silcnet.[ch].
1979 * Added `sockets' and `sockets_count' fields to the SilcClient
1980 object. They hold the sockets of the listenning sockets in
1981 the client. Listenning sockets may be for example the key
1982 agreement server. Affected file lib/silcclient/client.[ch].
1983 Added functions the silc_client_add_socket and the
1984 silc_client_del_socket. They are exported to the application
1987 * Added ~./silc/clientkeys to support other client's public keys.
1989 * Renamed verify_server_key client operation to verify_public_key
1990 and added one argument to indicate the type of the connection
1991 (server, client etc.).
1993 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Added silc_server_connection_auth_request to handle the
1996 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1997 silcd/packet_receive.[ch].
1999 * Added silc_server_send_connection_auth_request into the
2000 silcd/packet_send.c to send the connection auth request packet.
2002 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2005 * Fixed the public key authentication in responder side in the
2006 server. The `auth_data' pointer includes the SilcPublicKey
2007 not the path to the public key. Affected file silcd/protocol.c.
2009 * Implemented the public key authentication in the initiator side
2010 in the server. Affected file silcd/protocol.c.
2012 * Removed the [RedirectClient] config section from the server
2013 configuration. Is not needed and I don't want to implement it.
2015 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Cleaned up the CMODE command in the server. It now works
2018 correctly and supports all the modes defined in the protocol.
2019 Affected file is silcd/command.c.
2021 * Added `hmac_name' field to the SilcChannelEntry in the server
2022 to hold the default HMAC of the channel. It can be set when
2023 creating the channel (with JOIN command). Affected files
2026 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2027 type to indicate the change of the current cipher and hmac
2028 on the channel. Client can safely ignore the <cipher> argument
2029 (if it chooses to do so) since the CHANNEL_KEY packet will
2030 force the channel key change anyway. The <hmac> argument is
2031 important since the client is responsible of setting the new
2032 HMAC and the hmac key into use.
2034 * Fixed the CMODE command in the client library as well.
2036 * Tested CMODE command in router environment successfully.
2038 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Show the version of the remote client (or server) when connecting
2041 to the server. It is logged to the log file. Affected file
2042 is silcd/protocol.c.
2044 * Fixed the KILLED notify handling in the client library. The
2045 client must be removed from all channels when receiving the
2048 Also, do not remove the client entry when giving the KILL
2049 command but when the KILLED notify is received.
2051 * Removed silc_idlist_find_client_by_nickname from the server.
2052 Not needed anymore. Affected files silcd/idlist.[ch].
2054 * Implemented the CHANNEL_CHANGE notify type handling to the
2055 server. Affected file silcd/server.c.
2059 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Added silc_server_send_notify_invite to send the INVITE
2062 notify between routers.
2064 * Implemented the INVITE command correctly to the server.
2066 * Implemented the INVITE notify type handling in the server.
2068 * Implemented the INVITE command to the client library and on the
2071 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Added function silc_server_get_client_resolve to find the
2074 client entry by ID from all ID lists and then resolve it
2075 (using WHOIS) if it cannot be found. Affected file is
2078 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Implemented the BAN command to the client library.
2082 * The JOIN command in the server now checks the invite list
2085 * Changed the silc_command_reply_payload_encode_va and the
2086 silc_command_payload_encode_va to support that if argument is
2087 NULL it ignores and checks the next argument. Affected file
2088 lib/silccore/silccommand.c.
2090 * Added silc_server_send_notify_ban to send the BAN notify
2091 type between routers.
2093 * Chaned the silc_notify_payload_encode to support that if
2094 argument is NULL it ignores and checks the next argument.
2095 Affected file lib/silccore/silcnotify.c.
2097 * Tested ban lists in router environment successfully.
2099 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Implemented BAN command to the server, in silcd/command.[ch].
2103 * Removed the BAN and INVITE_LIST modes from the CMODE command
2106 * Added function silc_string_match to regex match two strings.
2107 Affected files lib/silcutil/silcutil.[ch].
2109 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Redefined parts of the SilcChannelEntry in the server to support
2112 the new ban and invite lists.
2114 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2116 * Redefined the INVITE command. The same command can be used to
2117 invite individuals to the channel but also to manage the invite
2118 list of the channel (to add to and remove from the invite list).
2119 Updated the protocol specs.
2121 * Added new command SILC_COMMAND_BAN that can be used to manage
2122 the ban list of the channel. Updated the protocol specs.
2124 * Removed the channel modes: the SILC_CMODE_BAN and the
2125 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2126 in the CMODE command. The equivalent features are now available
2127 using INVITE and BAN commands. Updated the protocol specs.
2129 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2130 in the network about change in the current ban list. The notify
2131 type is not used by the client.
2133 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2134 support the invite lists.
2136 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Added new function silc_string_regexify that converts string
2139 including wildcard characters into regex string that can
2140 be used by the GNU regex library. Added into the file
2141 lib/silcutil/silcutil.[ch].
2143 Added silc_string_regex_combine to combine to regex strings
2144 into one so that they can be used as one regex string by
2145 the GNU regex library. Added into the file
2146 lib/silcutil/silcutil.[ch].
2148 Added silc_string_regex_match to match two strings. It returns
2149 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2151 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Imported GNU regex to the soruce tree into lib/contrib.
2154 Fixed some compiler warning from the regex.c.
2156 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Fixed MOTD command in the server to work in router environment.
2160 * Fixed the MOTD command in the client library to support
2161 the server argument in the command.
2163 * Added `nickname_len' argument to the silc_idlist_add_client
2164 in the server, as the `nickname' argument may be binary data
2167 * Added silc_idlist_get_channels to return all channels from
2170 * Implemented LIST command to the server. Affected file is
2173 * Implemented the LIST command to the client library and on the
2176 * Added [<user count>] argument to the LIST command reply.
2177 With private channels the user count is not shown.
2179 * Updated TODO and README.
2181 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * The client entry's data.registered must be TRUE even with
2184 global client entry on global client list. The data.registered
2185 is used to check whether the client is anymore in the network,
2186 for example with WHOWAS command so it must be valid.
2188 * Fixed the WHOWAS command in the server. It now actually works
2189 in router environment. Added function into silcd/command_reply.c
2190 silc_server_command_reply_whowas_save.
2192 * Added silc_idlist_purge function to the silcd/idlist.c
2193 to periodically purge the ID Cache.
2195 * Fixed INFO command in the server. It works now in router
2196 environment. Added <server name> argument to the INFO command
2197 reply. Updated the protocol specs.
2199 * Fixed minor bug in silc_idcache_purge to not purge if the
2200 expire value is zero.
2202 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2203 they were buggy because of the WHOWAS information.
2205 * Fixed local command MSG to handle the async resolving of
2206 the remote client properly. It used to fail the first MSG.
2207 Affected file silc/local_command.c.
2209 * Added `data_len' field to SilcIDCache context.
2211 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Update TODO. Todo in commands in the server.
2215 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2218 used by routers as broadcast packet to inform other routers
2219 about the changed user mode.
2221 Implemented the notify handling in the server. Affected file is
2222 silcd/packet_receive.c. Added the function
2223 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2225 * Added new generic Channel Payload and deprecated the New Channel
2226 Payload. The New Channel Payload is now the generic Channel
2229 * Added new argument `mode' to the silc_server_send_new_channel
2230 as it is required in the Channel Payload now.
2232 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2233 and created a new and real SilChannelPayload to represent the
2234 new generic Channel Payload. Implemented the encode/decode
2235 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2237 * Added silc_server_get_client_channel_list to return the list
2238 of channels the client has joined for WHOIS command reply.
2239 Affected file silcd/server.[ch].
2241 * Implemented the channel list sending in the WHOIS command reply
2242 in server and in the client.
2244 Implemented the channel list displaying on the user interface
2245 as well. Affected file silc/client_ops.c.
2247 * Added silc_channel_payload_parse_list to parse list of Channel
2248 Payloads. It returns SilcDList list of SilcChannelPayloads.
2249 Client for example can use this function to parse the list of
2250 channels it receives in the WHOIS command reply. The caller
2251 must free the list by calling silc_channel_payload_list_free.
2252 Affected files lib/silccore/silcchannel.[ch].
2254 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Added one new argument <user mode> to the WHOIS command reply
2257 to return the mode of the user in SILC. Updated the protocol
2260 Implemented it to the server and client.
2262 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Fixed the mode printing on the user interface on joining.
2265 Affected file silc/client_ops.c.
2267 * Implemented the UMODE command and user modes in general to the
2268 client library and to the user interface.
2270 * Implemented the UMODE command to the server.
2272 * The server now sends UNKNOWN_COMMAND error status if client sends
2273 unknown command. Affected file silcd/command.c.
2275 * All server commands now handle the command identifier the right
2276 way when sending the command reply to the client. The client can
2277 use to identify the command replies with the identifier.
2279 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Added silc_server_get_client_route to resolve the route to
2282 the client indicated by the client ID. Affected file is
2285 * Added silc_server_relay_packet as general function to relay
2286 packet to arbitrary destination. This deprecates functions
2287 like _send_private_message_key, _relay_notify etc. Affected
2288 file is silcd/packet_send.[ch].
2290 Removed silc_server_send_key_agreement,
2291 silc_server_send_private_message_key and
2292 silc_server_packet_relay_notify functions from the file
2293 silcd/packet_send.[ch].
2297 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2298 server. Affected file silcd/packet_receive.[ch].
2300 * Implemented the KILL command to the client. Implemented the
2301 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2302 Affected files lib/silcclient/command[_reply].c and
2303 lib/silcclient/client_notify.c. Implemented the KILL notify
2304 printing in the user inteface.
2306 * Fixed a lot silc_parse_nick memory leaks from the client
2307 library in the file lib/silcclient/command.c.
2309 * Changed the silc_server_send_notify_on_channels's `sender'
2310 argument from SilcSocketConnection to SilcClientEntry to
2311 check the sender as entry and not as connection object and not
2312 to send to the client provided as argument. The affected file
2313 is silcd/packet_send.[ch].
2315 * The notify packets that are destined directly to the client used
2316 to not to be processed by the server. Now changed that and the
2317 server processes all notify packets. After relaying the packet
2318 to the client the notify packet is processed in the server.
2320 * The silc_server_free_client_data now checks whether there is
2321 pending outgoing traffic for the client and purges the data to
2322 the network before removing the client entry.
2324 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2327 an client is killed from the SILC Network. Updated the protocol
2330 Added new function silc_server_send_notify_killed to the
2331 silcd/packet_send.[ch].
2333 * Added function silc_server_packet_relay_notify to relay notify
2334 packets that are destined directly to a client. In this case
2335 the server does not process the notify packets but merely relays
2336 it to the client. Affected file silcd/packet_send.[ch].
2338 Added also silc_server_packet_process_relay_notify to check
2339 whereto relay the notify. Affected file is
2340 silcd/packet_receive.[ch].
2342 * Implemented the KILL command to the server.
2346 * Added the backup schema desgined last fall to the protocol
2347 specs for everyone to see. The specification is in the
2348 *-spec-xx.txt draft and the packet type definitions for the
2349 backup routers is in *-pp-xx.txt draft. Thusly, added also
2350 new packet type SILC_PACKET_CELL_ROUTERS.
2352 * A big security problem in the implementation discovered. The
2353 signoff of an client did not cause new channel key generation
2354 which it of course should've done. The channel keys must be
2355 always re-generated when client leaves (or signoffs) the channel.
2356 The silc_server_remove_from_channels funtion now handles
2357 the channel key re-generation.
2359 * Added `sender' argument to the silc_server_send_notify_on_channels
2360 to not to send the client provided as argument. Affected file
2361 silcd/packet_send.[ch].
2363 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Implemented OPER and SILCOPER commands into the server and
2368 * Added silc_auth_verify and silc_auth_verify_data to verify
2369 the authentication directly from the authentication payload.
2370 It supports verifying both passphrase and public key based
2371 authentication. Affected file lib/silccore/silcauth.[ch].
2373 * Added `hash' field to the SilcIDListData structure. It is the
2374 hash negotiated in the SKE protocol. Affected file is
2377 * Slight redesigning of the SilcAuthPayload handling routines.
2378 Do not send SilcPKCS but SilcPublicKey as argument.
2380 * Implemented the public key authentication support to the
2381 serverconfig. The public key is loaded from the provided path
2382 and saved as authentication data to void * pointer. Thus,
2383 changed the unsigned char *auth_data to void *auth_data;
2385 * Fixed SHUTDOWN command to send the reply before the server
2386 is shutdown. :) Affected file silcd/command.c.
2388 * Fixed fatal bug in CONNECT command. The hostname was invalid
2389 memory and server crashed. Affected file silcd/command.c.
2391 * Fixed fatal bug in CLOSE command. The server_entry became
2392 invalid but was referenced later in the command. Affected file
2395 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Fixed fatal bug in failure packet handling. Server ignored
2398 the failure and thus crashed when it came.
2402 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2405 that the command may be executed only once in (about) 2 seconds.
2406 The old SILC_CF_LAG flag is same but allows command bursts up
2407 to five before limiting.
2409 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2410 server code. Various commands now includes the CF_LAG_STRICT
2411 flag to disallow any kind of miss-use of the command.
2413 * Fixed the silc_buffer_unformat to not to allocate any data
2414 if the length of the data is zero. It used to allocate the
2415 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2417 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Changed the format of AdminConnection configuration section
2420 in the server. Added username of the admin to the format.
2421 Affected files silcd/serverconfig.[ch].
2423 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2424 to return admin configuration data by host, username and/or
2427 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Implemented WHOWAS command to the server. Added the functions:
2431 silc_server_command_whowas_parse,
2432 silc_server_command_whowas_send_reply,
2433 silc_server_command_whowas_from_client and
2434 silc_server_command_whowas_from_server
2436 * Added <Client ID> argument to the WHOWAS command reply. Updated
2437 the protocol specs accordingly.
2439 * Implemented WHOWAS command and command_reply to the client
2442 Implemented the WHOWAS printing on the user interface.
2444 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Added new argument to the WHOWAS command reply, the real name.
2447 It is an optional argument. Updated the protocol specs.
2449 * Added SilcIDCacheDestructor callback that is registered when
2450 the SilcIDCache is allocated. The callback is called when
2451 an cache entry in the ID Cache expires, or is purged from the
2452 cache. Added into lib/silccore/idcache.[ch].
2454 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2455 to destruct the client entries when the cache entry expires.
2456 Other ID Cache's in server and in the client library ignores
2459 * If the ID Cache entry's `expire' field is zero then the entry
2460 never expires. Added boolean `expire' argument to the
2461 silc_idcache_add function in the lib/silccore/idcache.[ch].
2462 If it is TRUE the default expiry value is used.
2464 * Added silc_server_free_client_data_timeout that is registered
2465 when client disconnects. By default for 5 minutes we preserve
2466 the client entry for history - for WHOWAS command.
2468 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Added support to the server to enforce that commands are not
2471 executed more than once in 2 seconds. If server receives
2472 commands from client more frequently, timeout is registered
2473 to process the commands. Affected file silcd/command.c.
2474 Added new function silc_server_command_process_timeout.
2476 * Changed NICK_NOTIFY handling in client library to check that
2477 if the client's nickname was changed, so there is no need to
2478 resolve anything from the server.
2480 * Removed error printing from the WHOIS and IDENTIFY commands.
2481 If error occurs then it is ignored silently in the client library.
2482 The application, however, may map the received error to
2483 human readable error string. The application currently maps
2484 the NO_SUCH_NICKNAME error to string.
2486 * Made the command status message public to the application. Moved
2487 them from lib/silcclient/command_reply.c to
2488 lib/silcclient/command_reply.h. The application can map the
2489 received command status to the string with the
2490 silc_client_command_status_message function.
2492 * Added check to the server to check that client's ID is same
2493 as the Source ID in the packet the client sent. They must
2496 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Added dist-bzip hook to the Makefile.am to make bzip2
2499 compressed distributions.
2501 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Server now enforces the maximum length for the nickname and
2504 the channel as protocol specification dictates. 128 bytes for
2505 nickname and 256 bytes for channel name.
2507 * Moved the WHOIS printing to the application. The client libary
2508 does not print out the WHOIS information anymore, the application
2509 must do it. Renamed silc_client_command_reply_whois_print to
2510 the silc_client_command_reply_whois_save.
2512 The client's idle time is also sent to the application now, and
2513 the idle is shown on screen.
2515 * Added silc_client_command_reply_identify_save to save the
2516 received IDENTIFY entries.
2518 * Do not check for channel private keys in message sending and
2519 reception if the channel does not have the PRIVKEY mode set.
2520 Affected file lib/silclient/client_channel.c.
2522 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2525 just surfaced after chaning the JOIN procedure.
2527 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Added silc_client_get_clients_by_list to get client entries
2530 from Client ID list, that is returned for example by JOIN
2531 and USERS command replies. The application should use this
2532 function for example when JOIN command reply is received to
2533 resolve the clients already on the channel (library does not
2534 do that anymore as USERS command reply is not used in the JOIN
2535 procedure anymore). Affected files lib/silcclient/silcapi.h and
2536 lib/silcclient/idlist.c.
2538 * JOIN command reply and USERS command reply returns now SilcBuffer
2539 pointers instead of unsigned char pointers when returning
2540 the client list and mode list.
2542 * Added <Client ID> argument to the JOIN command reply, mainly
2543 for the server to identify for which client the command was
2544 originally sent. Updated protocol specs accordingly.
2546 * Added SilcDlist private_key pointer to the SilcChannelEntry
2547 in the client to support the channel private keys. Affected
2548 file is lib/silcclient/idlist.h.
2550 * Added SilcChannelPrivateKey argument to the function
2551 silc_client_send_channel_message so that application can choose
2552 to use specific private ke if it wants to. If it is not provided,
2553 the normal channel key is used, unless private keys are set.
2554 In this case the first (key that was added first) is used
2555 as the encryption key.
2557 * Implemented the support for channel private key handling.
2558 Implemented the following functions:
2560 silc_client_add_channel_private_key,
2561 silc_client_del_channel_private_keys,
2562 silc_client_del_channel_private_key,
2563 silc_client_list_channel_private_keys and
2564 silc_client_free_channel_private_keys
2566 Affected file lib/silcclient/client_channel.c.
2568 * Added the support for the private keys in the channel message
2569 sending and encryption and in the message reception and
2570 decryption. Affected funtions are
2571 silc_client_send_channel_message and silc_client_channel_message.
2573 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Added SKE's key verify callback to the client library's
2576 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2578 * Removed the statement that server (or router) must send USERS
2579 command reply when joining to the channel so that the client
2580 knows who are on the channel. Instead, the client list and
2581 client's mode list is now sent in the JOIN command reply to the
2582 client who joined channel. This is better solution.
2584 * Added function silc_server_get_users_on_channel and function
2585 silc_server_save_users_on_channel to the silcd/server.[ch].
2587 * Removed function silc_server_command_send_users from the
2590 * Do not show topic on the client library anymore. The topic is
2591 sent in the command reply notify to the application and the
2592 application must show the topic now.
2594 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Added client searching by nickname hash into the IDENTIFY and
2597 WHOIS commands in the server as they were clearly missing from
2598 them. Affected file is silcd/command.c.
2600 * Fixed a bug in private message receiving in the client library.
2601 The remote ID was freed and it wasn't supposed, now it is
2604 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Minor fix to the channel payload; allocate the data area, as it
2607 needs to be of specific length.
2609 * If the key agreement port is zero then the operating
2610 system will define the bound port. Affected files are
2611 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2613 * Added new function silc_channel_payload_decrypt into the file
2614 lib/silccore/silcchannel.[ch].
2616 * Moved the channel message etc, check from silc_packet_decrypt
2617 to applications. The library calls now a generic
2618 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2619 when the packet is either normal or special. This was done to
2620 allow more wide range of checking that was not allowed when
2621 the code was in library. Now applications can do virtually any
2622 checks to the packet and return to the library the decision how
2623 the packet should be processed. Affected files are
2624 lib/silccore/silcpacket.[ch].
2626 Added silc_server_packet_decrypt_check to the server and
2627 silc_client_packet_decrypt_check to the client library.
2629 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2630 to send with specified source and destination information.
2632 * Channel message delivery between routers was broken after the
2633 channel key distribution was fixed earlier. The channel key
2634 was used be to distributed to other routers as well which is not
2635 allowed by the protocol. Now this is fixed and channel keys
2636 really are cell specific and the channel message delivery between
2637 routers comply with the protocol specification.
2639 * Fixed various commands in server to check also the global list
2640 for the channel entry and not just the local list. The affected
2641 file silcd/command.c.
2643 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2645 * Added assert()s to buffer formatting and unformatting routines
2646 to assert (if --enable-debug) when error occurs. Affected
2647 file: lib/silcutil/silcbuffmt.c.
2649 * Changed to auto-reconnect to check whether the remote host is
2650 router and register the re-connect timeout if it is. It used
2651 to check that whether we are normal server, but router must do
2652 auto-reconnect with another router as well. Affected file
2655 * Removed the [<key len>] option from CMODE command as the cipher
2656 name decides the key length, nowadays. See the defined ciphers
2657 from the protocol specification.
2659 * Added [<hmac>] option to the CMODE command to define the HMAC
2660 for the channel. Added SILC_CMODE_HMAC channel mode.
2662 * Added [<hmac>] option for the JOIN command so that user can
2663 select which HMAC is used to compute the MACs of the channel
2666 * Added Hmac field to the Channel Message Payload. The integrity
2667 of plaintext channel messages are now protected by computing
2668 MAC of the message and attaching the MAC to the payload. The
2669 MAC is encrypted. Now, it is clear that this causes some
2670 overhead to the size of the packet but rationale for this is that
2671 now the receiver can verify whether the channel message decrypted
2672 correctly and also when private keys are set for the channel the
2673 receiver can decrypt the packet with several keys and check from
2674 the MAC which key decrypted the message correctly.
2676 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2677 lib/silccrypt/silccipher.[ch].
2679 * Added silc_hash_len to return the digest length into the
2680 lib/silcrypt/silchash.[ch].
2682 * Rewrote parts of Silc Channel Payload interface in the
2683 lib/silccore/silcchannel.[ch]. The encode function now also
2684 encrypts the packet and parse function decrypts it.
2686 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Fixed a minor formatting bug in the SKE's key material processing.
2689 It actually might have processed the keys wrong way resulting
2692 * Redefined the mandatory HMAC algorithms and added new algorithms.
2693 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2694 and hmac-md5 truncated to 96 bits. The mandatory is now
2695 hmac-sha1-96. Rest are optional (including the one that used
2696 to be mandatory). Rationale for this is that the truncated HMAC
2697 length is sufficient from security point of view and can actually
2698 make the attack against the HMAC harder. Also, the truncated
2699 HMAC causes less overhead to the packets. See the RFC2104 for
2702 * Added new [hmac] configuration section. The SKE used to use
2703 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2704 is of course wrong. The official names that must be proposed in
2705 the SKE are the ones defined in the protocol specification
2706 (hmac-sha1-96 for example). The user can configure any hmac
2707 using any hash function configured in the [hash] section. At
2708 least, the mandatory must be configured.
2710 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2712 * Added HMAC list to the SKE proposal list. It has now both
2713 hash algorithm list and HMAC list. This makes the protocol
2714 incompatible with previous versions. The SKE now seems to work
2715 the way it is supposed to work, for the first time actually.
2717 * Defined plain Hash algorithms to the protocol specification.
2720 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Implemented support for key agreement packets into the server.
2723 Added functions silc_server_key_agreement and
2724 silc_server_send_key_agreement. Other than these functions,
2725 server has nothing to do with this packet.
2727 * Added support for private message key packets into the server.
2728 Added functions silc_server_private_message_key and
2729 silc_server_send_private_message_key.
2733 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2734 called in the protocol's final callback instead in the END
2735 protocol state. This makes a little more sense and in the same
2736 time in client we can use the same protocol routines for normal
2737 key exchange and to key agreement packet handling as well.
2739 * Added to both client's and server's KE protocol context the
2740 SilcSKEKeyMaterial pointer to save the key material. We will
2741 bring the key material to the protocol's final callback by doing
2742 this. The final callback must free the key material.
2744 * Added SKE's packet_send callback into client's KE protocol
2745 context so that the caller can choose what packet sending function
2746 is used. This way we can use different packet sending when
2747 doing normal SKE when doing key agreement packet handling (in
2748 the key agreement packet handling we do not want to encrypt
2751 * Implemented the responder side of the key agreement routines
2752 in the client. The client can now bind to specified port and
2753 accept incoming key negotiation. The key material is passed
2754 to the application after the protocol is over.
2756 * Implemented the processing of incoming Key Agreement packet
2757 in the client. Added function silc_client_key_agreement to
2760 * Implemented the intiator side of the key agreement routines
2761 in the client. The client can now initiate key agreement with
2762 another remote client. The key material is passed to the
2763 application after the protocol is over.
2765 * Created client_keyagr.c to include all the key agreement
2768 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2769 SILC_TASK_CALLBACK except that it is not static.
2771 * Created client_notify.c and moved the Notify packet handling
2772 from the client.[ch] into that file.
2774 * Created client_prvmsg.c and moved all private message and
2775 private message key routines from the client.[ch] into that file.
2777 * Create client_channel.c and moved all channel message and
2778 channel private key routines from the client.[ch] into that file.
2780 * Changed silc_client_get_client_by_id_resolve to resolve with
2781 WHOIS command instead of IDENTIFY command, in the file
2782 lib/silclient/idlist.c.
2784 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Implemented the SKE's responder side to the Client library.
2788 * When FAILURE is received to the protocol do not trust it
2789 blindly. Register a timeout to wait whether the remote closes
2790 the connection as it should do it, only after that process the
2791 actual failure. This was changed to both client and server.
2793 * Added client_internal.h to include some of the structures
2794 there instead of client.h in lib/silcclient/.
2796 * Added function silc_task_unregister_by_callback to unregister
2797 timeouts by the callback function.
2799 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Some "Incomplete WHOIS info" errors has been appearing on the
2802 log files. Took away the entry->userinfo check from WHOIS
2803 reply sending. The entry->userinfo is now " " if client did not
2804 provide one. I thought this was fixed earlier but something
2805 is wrong still. Let's see if the error still appears.
2807 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Fixed a minor bug in the login when the channel key is
2810 re-generated in the server. It used to generate the key in
2811 wrong order and thus caused problems in the channel traffic.
2813 * Fixed a minor bug in channel key distsribution after
2814 KICK command. The key was not sent to the router even though
2817 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Added silc_ske_process_key_material_data as generic routine
2820 to process any key material as the SILC protocol dictates. The
2821 function is used by the actual SKE library but can be used by
2822 applications as well. This relates to the private message keys
2823 and the channel private keys since they must be processed the
2824 same way the normal SILC session keys. The protocol dictates
2825 this. Affected files: lib/silcske/silcske.[ch].
2827 Added also silc_ske_free_key_material to free the
2828 SilcSKEKeyMaterial structure.
2830 * Defined silc_cipher_set_key function to set the key for
2831 cipher without using the object's method function. The affected
2832 files: lib/silccrypt/silccipher.[ch].
2834 * Implemented silc silc_client_add_private_message_key,
2835 silc_client_add_private_message_key_ske,
2836 silc_client_del_private_message_key,
2837 silc_client_list_private_message_keys and
2838 silc_client_free_private_message_keys functions in the
2841 Added functions silc_client_send_private_message_key to send
2842 the Private Message Key payload and silc_client_private_message_key
2843 to handle incoming Private Message Key payload.
2845 * Added Cipher field to the Private Message Key payload to set
2846 the cipher to be used. If ignored, the default cipher defined
2847 in the SILC protocol (aes-256-cbc) is used.
2849 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Removed lib/silcclient/ops.h file.
2853 Redefined parts of the SILC Client Library API. Created new
2854 file silcapi.h that deprecates the ops.h file and defines the
2855 published Client Library API. Defined also private message key
2856 API and channel private key API into the file.
2858 This is the file that the application must include from the
2859 SILC Client Library. Other files need not be included by
2860 the application anymore.
2862 * Added new key_agreement client operation callback and also
2863 defined the Key Agreement library API for the application.
2865 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2868 is used by clients to request key negotiation between another
2869 client in the SILC network. If the negotiation is started it
2870 is performed using the SKE protocol. The result of the
2871 negotiation, the secret key material, can be used for example
2872 as private message key.
2874 Implemented the Key Agreement payload into the files
2875 lib/silccore/silauth.[ch].
2877 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Redefined ciphers for the SILC protocol. Added some new ciphers
2880 and defined the key lengths for the algorithms. Changed the
2881 code accordingly. The default key length is now 256 bits.
2883 * Fixed SKE key distribution function silc_ske_process_key_material
2884 when the key length is more than 128 bits. The default key
2885 length in SILC is now 256 bits.
2887 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2888 to indicate unsupported algorithm.
2890 * Renamed rijndael.c to aes.c and all functions as well.
2892 * Fixed a long standing channel key setting bug in client library.
2893 Weird that it has never surfaced before.
2895 * Fixed bug in channel deletion. If the entire channel is removed
2896 then it must also delete the references of the channel entry
2897 from the client's channel list as the client's channel entry and
2898 the channel's client entry share same memory.
2900 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Implemented CONNECT and SHUTDOWN commands in the client.
2904 * Implemented CLOSE command to the client.
2906 * Added the function silc_idlist_find_server_by_name into the
2907 files silcd/idlist.[ch].
2909 Added the function silc_idlist_find_server_by_conn into the
2910 files silcd/idlist.[ch].
2912 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * DIE command was renamed to SHUTDOWN. Updated the both code
2917 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2918 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2920 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2923 * Added function silc_server_create_connection function to create
2924 connection to remote router. My server implementation actually
2925 does not allow router to connect to normal server (it expects
2926 that normal server always initiates the connection to the router)
2927 so the CONNECT command is only good for connecting to another
2930 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2933 or some other client was kicked from the channel.
2935 Implemented the handling of the notify type to both client
2938 Implemented silc_server_send_notify_kicked to send the KICKED
2939 notify. It is used to send it to the server's primary router.
2941 * Implemented the KICK command into server and client.
2943 * Added `query' argument to the silc_idlist_get_client function
2944 to indicate whether to query the client from server or not if
2947 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2948 to indicate that the client is not channel founder.
2952 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Removed the rng context from SilcPacketContext structure and
2955 changed that the packet routine uses the Global RNG API.
2957 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added support for quit message that client can "leave" on the
2960 channel when it quits the SILC. It is ditributed inside the
2961 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2963 Added silc_server_free_client_data that will take the
2964 signoff message as argument.
2966 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2968 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Updated parts of the protocol specification to keep it up
2973 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2976 payloads in one packet.
2978 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2979 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2980 use now the new List flag.
2982 * Also deprecated the following packet types: REPLACE_ID,
2983 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2985 * Added list support for Notify packet in server.
2987 * Added silc_server_send_notify_channel_change to send the
2988 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2989 the silc_server_send_replace_id.
2991 * Added silc_server_send_notify_nick_change to send the
2992 NICK_CHANGE notify type. Deprecates the function
2993 silc_server_send_replace_id.
2995 * Added silc_server_send_notify_join to send the JOIN notify type.
2996 Deprecates the function silc_server_send_new_channel_user.
2998 * Added silc_server_send_notify_leave to send LEAVE notify type.
2999 Deprecates the function silc_server_send_remove_channel_user.
3001 * Added silc_server_send_notify_cmode and
3002 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3003 types. Deprecates the silc_server_send_set_mode function.
3005 * Added SERVER_SIGNOFF notify type to indicate that server has
3006 quit. This means that all clients on the channel from that
3007 server will drop. This can be also used when netsplit happens.
3009 Deprecated REMOVE_ID packet type since it is not needed anymore
3012 Added silc_server_send_notify_server_signoff to send the
3013 SERVER_SIGNOFF notify type. Deprecates the function
3014 silc_server_send_remove_id.
3016 Added also silc_server_send_notify_signoff to send the
3017 SIGNOFF notify type.
3019 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3020 SILC protocol from this day on. Changed the protocol
3021 specification as well.
3023 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3024 notify type. It is used between routers to notify about
3025 topic changes on a channel.
3027 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3030 * Partly updated the protocol specification to comply with the
3031 changes now made. It is still though a bit outdated.
3033 * The JOIN notify type now takes one extra argument <Channel ID>.
3034 The packet used to be destined to the channel but now the
3035 JOIN type may be sent as list thus it is impossible to
3036 destine it to any specific channel. By adding this argument
3037 it is again possible.
3039 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added CREDITS file. The CHANGES and CREDITS file will appear
3042 in the distribution as well.
3044 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3047 types in the server's silcd/packet_receive.c.
3049 * Implemented CMODE and CUMODE to work in router environment.
3051 * Fixed minor encoding and decoding buglet from the
3052 lib/silccore/silcmode.c.
3054 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3057 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3059 * Changed all SilcConfigServer* and silc_config_server* to
3060 SilcServerConfig* and silc_server_config*, respectively.
3063 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Associated the ID (client or server ID) to the Authentication
3066 Payload to avoid any possibility of forging. Updated the
3067 protocol specification and the code accordingly.
3069 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * The RSA key length is now save to the RsaKey context in the
3072 key generation process in lib/silccrypt/rsa.c. The key length
3073 is now used to figure out the maximum size of the block allowed
3074 to be encrypted/signed.
3076 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3077 is equivalent to the silc_mp_mp2bin but does not allocate any
3080 * Changed silc_mp_mp2bin API to take length argument. If it is
3081 non-zero then the buffer is allocated that large. If zero, then
3082 the size is approximated using silc_mp_sizeinbase, which however
3085 * Created Global RNG API which is global RNG that application can
3086 initialize. After initializing, any routine anywhere in the
3087 code (including library) can use RNG without allocating a new
3088 RNG object. This was done to allow this sort of use of the
3089 RNG in code that has no chance to allocate RNG object. All
3090 applications currently allocate this and many routines in the
3091 library use this. Affected file lib/silccrypt/silcrng.[ch].
3093 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3094 it to use the Global RNG API.
3096 * Defined Authentication Payload into protocol specification that
3097 is used during SILC session to authenticate entities. It is
3098 used for example by client to authenticate itself to the server
3099 to obtain server operator privileges.
3101 Implemented this payload into the lib/silccore/silcauth.[ch].
3102 Implemented also routines for public key based authentication
3103 as the new protocol specification dictates.
3105 Moved definitions of different authentication methods from
3106 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3108 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3109 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3110 silc_pkcs_verify_with_hash functions into the file
3111 lib/silccrypt/silcpkcs.[ch].
3113 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * The client entry's userinfo pointer must be always valid.
3116 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3117 will fail since it requires the userinfo. Now, the userinfo
3118 is allocated as "" if actual userinfo does not exist. Actually,
3119 it must exist and it is totally Ok to drop client connections
3120 that does not announce the userinfo. However, we will make
3121 this workaround for now.
3123 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3124 to return the remote port by socket.
3126 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3129 SILC_SERVER_PENDING_EXEC and added an new macro
3130 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3131 data or when error occurs while processing the pending command.
3133 Added new argument `destructor' into silc_server_command_pending
3134 and to the SilcServerCommandPending object. This destructor is
3135 now called after calling the pending callback or if error occurs
3136 immediately. If error occurs the actual pending callback won't
3137 be called at all - only the destructor. The destructor may be
3138 NULL if destructor is not needed.
3140 All this applies for client library code as well. Similar
3141 changes were made there as well for the pending commands.
3143 In the client, the application must now allocate the
3144 SilcClientCommandContext with the silc_client_command_alloc
3147 * Added reference counter to the SilcServerCommandContext. Added
3148 function silc_server_command_alloc and silc_server_command_dup
3151 Same type of functions added to the client library for the same
3154 * Removed the cmd_ident from IDListData away since it is now
3155 global for all connections. It is the command identifier used
3156 in command sending and with pending commands. The affected file
3159 * Added reference counter to the SilcSocketConnection objecet to
3160 indicate the usage count of the object. The object won't be
3161 freed untill the reference counter hits zero. Currently only
3162 server uses this, and client ignores it. The client must be
3163 set to use this too later. The affected files are
3164 lib/silccore/silcsockconn.[ch]. Added also the function
3165 silc_socket_dup to increase the reference counter.
3167 This was mainly added because it is possible that the socket
3168 is removed underneath of pending command or other async
3169 operation. Now it won't be free'd and proper DISCONNECTING
3170 flags, etc. can be set to avoid sending data to connection that
3171 is not valid anymore.
3173 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3174 the connection. After that it sets SILC_SET_DISCONNECTED.
3175 It is, however, possible that the socket data is not still freed.
3176 The silc_server_packet_process now checks that data is not
3177 read or written to connection that is DISCONNECTED. The socket
3178 get's freed when the reference counter hits zero.
3180 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Changed the client operation API: channel_message operation's
3183 `sender' is now the client entry of the sender, not the nickname
3184 and the `channel' is the channel entry, not the channel name.
3186 In the private_message operation the `sender' is now also the
3187 client entry of the sender not the nickname.
3189 Affected file is lib/silcclient/ops.h and all applications
3190 using the client operations.
3192 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Moved the calling of ops->connect() from connect_to_server_final
3195 into receive_new_id functin since that is the point when the
3196 client is actually allowed to send traffic to network. The
3197 affected file is lib/silcclient/client.c.
3199 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3202 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3203 (if needs broadcasting) instead of broadcasting the packets one
3204 by one which would make a burst in the network traffic.
3206 * Added `broadcast' argument to the functions in silcd/server.[ch]
3207 silc_server_create_new_channel[_with_id] to indicate whether
3208 to send New Channel packet to primary router.
3210 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Added new function into the silcd/server.[ch] files:
3213 silc_server_create_new_channel_with_id to create new channel with
3214 already existing Channel ID.
3216 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3217 lib/silccore/silcpacket.h. This packet is used t send list of
3218 Set Mode payloads inside one packet. Server uses this to set
3219 the modes for the channels and clients on those channels, that it
3220 announced to the router when it connected to it. The protocol
3221 specification has been updated accordingly.
3223 * The silc_server_new_channel did not handle the packet coming
3224 from normal server as it normally does not send that. However,
3225 when it announces its channels it does send it. Implemented
3226 the support for that.
3228 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3229 into the file lib/silccore/id.h.
3231 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Fixed memory leaks in the functions silc_idlist_del_client,
3234 silc_idlist_del_channel and silc_idlist_del_server in the file
3235 silcd/idlist.c. All of those leaked like a sieve.
3237 * Fixed some small memory leaks in the client's function
3238 silc_client_notify_by_server.
3240 * Added functions into silcd/server.c: silc_server_announce_clients,
3241 silc_server_announce_channels and silc_server_announce_server.
3242 These functions are used by normal and router server to announce
3243 to its primary router about clients, channels and servers (when
3244 router) that we own. This is done after we've connected to the
3247 These functions effectively implements the following packet types:
3248 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3249 and SILC_PACKET_NEW_ID_LIST.
3251 * Added new functions into the silcd/packet_receive.[ch]:
3252 silc_server_new_id_list, silc_server_new_channel_list and
3253 silc_server_new_channel_user_list to handle the incoming
3254 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3256 * Added support of changing Channel ID in the function
3257 silc_server_replace_id. If the server that announces a channel
3258 to the router already exists in the router (with same name but
3259 with different Channel ID), router is responsible to send
3260 Replace ID packet to the server and force the server to change
3261 the Channel ID to the one router has.
3263 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3264 client that the Channel ID has been changed by the router. The
3265 normal server sends this to the client. Client must start using
3266 the new Channel ID as the channel's ID.
3268 Implemented handling of this new type into lib/silcclient/client.c
3269 into the function silc_client_notify_by_server.
3271 * Added new function silc_idlist_replace_channel_id into the files
3272 silcd/idlist.[ch] to replace the Channel ID.
3274 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Call silc_server_command_identify_check always when processing
3277 the IDENTIFY command in silcd/command.c
3279 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3282 send keepalive packets. The packet can be sent by clients,
3283 servers and routers.
3285 Added function silc_socket_set_heartbeat into the file
3286 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3287 If not set, the heartbeat is not performed. The actual
3288 heartbeat is implemented in the low level socket connection
3289 library. However, application is responsible of actually
3292 Added silc_server_send_heartbeat to send the actual heartbeat
3293 packet into silcd/packet_send.[ch]. Server now performs
3294 keepalive with all connections.
3296 * Added silc_task_get_first function into lib/silcutil/silctask.c
3297 to return the timeout task with shortest timeout. There was a bug
3298 in task unregistration that caused problems. TODO has been
3299 updated to include that task system must be rewritten.
3301 * The client library will now resolve the client information when
3302 receiving JOIN notify from server for client that we know but
3303 have incomplete information.
3305 * Rewrote parts of silc_server_remove_from_channels and
3306 silc_server_remove_from_one_channel as they did not remove the
3307 channel in some circumstances even though they should've.
3309 * Encryption problem encountered in server:
3311 The LEAVE command used to send the Channel Key packet to the
3312 router immediately after generating it. However, the code
3313 had earlier sent Remove Channel user packet but not immediately,
3314 ie. it was put to queue. The order of packets in the router
3315 was that Channel Key packet was first and Remove Channel User
3316 packet was second, even though they were encrypted in the
3317 reverse order. For this reason, MAC check failed. Now, this
3318 is fixed by not sending the Channel Key packet immediately but
3319 putting it to queue. However, this is more fundamental problem:
3320 packets that are in queue should actually not be encrypted
3321 because packets that are sent immediately gets encrypted
3322 actually with wrong IV (and thus MAC check fails). So, packets
3323 that are in queue should be encrypted when they are sent to
3324 the wire and not when they put to the queue.
3326 However, the problem is that the current system has not been
3327 designed to work that way. Instead, the packet is encrypted
3328 as soon as possible and left to the queue. The queue is then
3329 just purged into wire. There won't be any fixes for this
3330 any time soon. So, the current semantic for packet sending
3333 o If you send packet to remote host and do not force the send
3334 (the packet will be in queue) then all subsequent packets to the
3335 same remote host must also be put to the queue. Only after the
3336 queue has been purged is it safe again to force the packet
3339 o If you send all packets immediately then it safe to send
3340 any of subsequent packets through the queue, however, after
3341 the first packet is put to queue then any subsequent packets
3342 must also be put to the queue.
3344 Follow these rules and everything works fine.
3346 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Added new function silc_server_remove_clients_by_server to
3349 remove all client entries from ID list when the server connection
3350 is lost. In this case it is also important to invalidate all
3351 client entires as they hold the invalid server entry. This
3352 fixes fatal bug when server has lost connection and will reconnect
3355 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Made some sanity checks to silc_server_daemonise like to check
3358 whether the requested user and group actually exists.
3360 * Added sanity check to SKE's silc_ske_responder_finish to check
3361 that the public and private key actually is valid.
3363 * Invalidate the client's nickname when receiving Replace ID
3364 packet and the Client ID is being replaced. This means that the
3365 server will query the nickname if someone needs it (client)
3368 * Sort the ID Cache in client library when the ID Cache data
3369 has changed (needs sorting).
3371 * Do not allow for SILC client to create several connections to
3372 several servers. The client does not support windows right now
3373 and generating multiple connections causes weird behaviour.
3375 Irssi-silc client does support windows and can handle several
3376 connections without problems, see: www.irssi.org and SILC plugin.
3378 * Fixed some places where client was added to the IDList. The
3379 rule of thumb is following (in order to get everything right):
3380 If the client is directly connected local client then the
3381 `connection' argument must be set and `router' argument must be
3382 NULL to silc_idlist_add_client function. If the client is not
3383 directly connected client then the `router' argument must
3384 bet set and the `connection' argument must be NULL to the
3385 silc_idlist_add_client function.
3387 * The funtion silc_server_packet_send_local_channel actually did
3388 not check whether the client was locally connected or not. It
3389 does that now. Fixed a bug related to LEAVE command.
3391 * Fixed Remove Channel User payload parsing bug in server's
3392 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3394 * The server's silc_server_save_channel_key now checks also the
3395 global ID list for the channel as it might not be in the local
3396 list. Fixed a bug related to LEAVE command.
3398 * Is this the end of the [<unknown>] buglet that has been lurking
3399 around for a long time? A little for loop fix in server's
3400 silc_server_command_whois_parse that is used by both IDENTIFY
3401 and WHOIS command. At least, this was a clear bug and a cause
3402 of one type of [<unknown>] buglet.
3404 * WHOIS and IDENTIFY commands call the function
3405 silc_server_command_[whois/identify]_check function even if
3406 we are not router server.
3408 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Added --with-gmp configuration option. If set the GMP
3411 is always compiled in the SILC source tree. If not set then
3412 it is checked whether the system has the GMP3 installed. If
3413 it has then the GMP won't be compiled (the system's headers
3414 and library is used), if it doesn't have it then the GMP is
3415 compiled in the SILC source tree.
3417 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Changed RSA private exponent generation to what PKCS #1
3420 suggests. We try to find the smallest possible d by doing
3421 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3422 not security fix but optimization.
3424 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added new config entry [Identity] to fork the server and run
3427 it as specific user and group. A patch from Bostik.
3429 * Imported Dotconf configuration library into lib/dotconf.
3430 This will be used to create the SILC configuration files later.
3431 It will appear in the distsribution after this commit.
3433 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * A big code auditing weekend happening. Auditing code for
3436 obvious mistakes, bugs and errors. Also, removing any code
3439 Removed files for being obsolete:
3441 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3442 inline in the file lib/silcutil/silcbuffer.h)
3444 o lib/silcutil/silcbufutil.c (the header has inline versions)
3446 Changed code to fix possible error conditions:
3448 o The buffer formatting routines now check that the destination
3449 buffer really has enough space to add the data. This applies for
3450 both buffer formatting and unformatting
3451 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3452 unformatting was changed to accomodate following rules:
3453 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3454 sent to the function while XXX_*STRING will not allocate or copy
3455 the data into the buffer. Instead it sets the pointer from the
3456 buffer into the pointer sent as argument (XXX_*STRING used to
3457 require that the pointer must be allocated already). This change
3458 makes this whole thing a bit more consistent and more optimized
3459 (note that the data returned in the unformatting with XXX_*STRING
3460 must not be freed now). The routines return now -1 on error.
3462 o Tried to find all code that use buffer_format and buffer_unformat
3463 and added return value checking to prevent formatting and
3464 especially unformatting errors and possible subsequent fatal
3467 o Changed ske->x and ske->KEY to mallocated pointers in
3468 lib/silcske/silcske.h. Fixed possible data and memory leak.
3470 o Added return value checking to all *_parse* functions. Fixed
3471 many memory leaks as well.
3473 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3474 so that buffer overflows would not happen. All code now also
3475 checks the return value as it can fail.
3477 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Added reconnection support to server if the normal server looses
3480 its connection to the router (for example if router is rebooted).
3481 The server performs normal reconnection strategy implemented
3482 to the server. Affected file silcd/server.c.
3484 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Added new packet type SILC_PACKET_SET_MODE that is used to
3487 distribute the information about changed modes (for clients,
3488 channels and clients channel modes) to all routers in the
3489 network. Updated the protocol specification accordingly.
3491 Added functions into silcd/packet_send.c and
3492 silcd/packet_receive.c: silc_server_send_set_mode,
3493 silc_server_set_mode.
3495 Added new files silcmode.[ch] into lib/silccore that implements
3496 the encoding and decoding of Set Mode Payload. Added new type
3497 SilcSetModePayload. Moved the definitions of different modes
3498 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3500 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Oops, a little mistake in server's connection authentication
3503 protocol. The protocol is not ended with FAILURE but with
3504 SUCCESS if the authentication is Ok. :) Affected file is
3507 * Implemented NICK_CHANGE notify handling in server in the file
3508 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3509 the local clients on the channel. After the changing nickname
3510 in router environment snhould work and the [<unknown>] nickname
3511 should appear no more.
3513 The silc_server_replace_id function that receives the Replace ID
3514 payload now sends the NICK_CHANGE notify type also in the file
3515 silcd/packet_receive.c
3517 * Changed WHOIS and IDENTIFY command to support the maximum amount
3518 of arguments defined in protocol specs (3328 arguments). This
3519 fixed a bug that caused problems when there were more than three
3522 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added extra parameter, command identifier, to the
3525 silc_client_send_command so that explicit command identifier
3528 Changed that ID list routines uses specific command identifier
3529 when sending WHOIS/IDENTIFY requests to the server so that they
3530 can be identified when the reply comes back.
3532 Affected files lib/silcclient/command.[ch],
3533 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3535 * Added `sender' argument to silc_server_packet_send_to_channel
3536 to indicaet the sender who originally sent the packet to us
3537 that we are now re-sending. Ignored if NULL. Affected file
3538 silcd/packet_send.[ch].
3540 * Added some server statistics support in silcd/server_internal.h
3541 SilcServerStatistics structure and around the server code. Also
3542 send some nice statistics information when client is connecting
3545 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Fixed channel ID decoding in server's JOIN command reply in
3548 silcd/command_reply.c
3550 * Fixed braodcasting of replace ID payload to not to send it if
3551 we are standalone server in silcd/packet_receive.c.
3553 * Fixed all channel message sending routines to not to send
3554 packets to clients that has router set, since they are routed
3555 separately in the same function earlier. Affects file
3556 silcd/packet_send.c and all channel packet sending functions.
3558 * In USERS reply, res_argv[i] are not allocated, the table
3559 is allocated. Thus changed that free the table, not its
3562 * In server's whois_check and identify_check if the client is
3563 locally connected do not send any WHOIS commands - they are not
3566 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Fixed some minor bugs in client when sending WHOIS command. The
3569 arguments was in wrong order.
3571 * Removed statis function add_to_channel from server in
3572 silcd/command.c that was previously used with the joining but
3575 * Tested USERS command in router environment successfully with two
3576 routers, two servers and two clients.
3578 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Reorganized the USERS command and command reply in client library
3581 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3582 When the command is given by user we register a pending command
3583 callback that will reprocess the command after the reply has been
3584 received from the server. When reprocessing the packet we then
3585 display the information. Thus, the USERS information is displayed
3586 now in the command callback instead of in the command reply
3587 callback. The processing of the command is same as previously
3588 when server has sent the command reply in the JOINing process.
3590 * Added to USERS command in silcd/command_reply.c to join the client,
3591 we didn't use to know about, to the channel after we've created
3592 a client entry for it. Also, for clienet we did know already still
3593 check whether it is on the channel or not and add it if not.
3595 * Removed silc_server_command_join_notify as the function and its
3598 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3600 * Changed the client's pending command handling to the same as the
3601 server's pending command handling. It is also now possible to
3602 execute command reply functions from other command reply
3603 function as the function callbacks for commands and command
3604 replies are one and same. The pending commands are not static
3605 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3606 in client connection context. Thus, pending commands are server
3607 connection specific as it is convenient.
3609 Changed the function silc_client_command_pending and
3610 silc_client_command_pending_del and added new function
3611 silc_client_command_pending_check. Removed the
3612 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3615 * Added cmd_ident, current command identifier, to the client
3616 connection context in lib/silcclient/client.h to keep track on
3617 command identifiers used in command sending. Client's command reply
3618 function handling now supports the mandatory command identifiers.
3620 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3621 funtions in client to fully support pending command callbacks.
3623 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3624 as one of the arguments to the application in the command reply
3627 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3628 before first releasing SILC but came back. Now it is removed again
3629 and should come back nomore. The FORWARDED flag was used only
3630 by the JOINing procedure by forwarding the command packet to router.
3631 Now, the JOINing procedure has been changed to more generic (due
3632 to various router environment issues) and FORWARDED is not needed
3633 anymore for anything. The protocol specification is yet to be
3636 Now, removed silc_server_packet_forward from server and the flag
3637 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3639 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3641 * Renamed NAMES command to USERS command. The NAMES was named that
3642 due to historical reasons. Now it is renamed. Also, rewrote
3643 parts of the USERS command. The nickname list is not sent anymore
3644 by the server. Only Client ID and mode lists are sent in the USERS
3645 command. Changed this also to the protocol specification.
3647 The client now resolves the names and stuff after it receives
3648 the USERS list from the server when joining to the channel.
3650 * WHOIS and IDENTIFY commands has been changed to support multiple
3651 Client ID's per command. One can now search for multiple users
3652 in the network by sending only one WHOIS or IDENTIFY command.
3653 Changed the code and the protocol specifications.
3655 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3656 uses silc_server_command_whois_parse to parse the request. */
3658 * If normal server, do not parse the WHOIS and IDENTIFY requests
3659 before sending it to the router. Saves some time.
3661 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Fixed JOIN command on client library. Wrong number of arguments
3664 used to crash the client.
3666 * Added silc_server_channel_has_global function to check whether
3667 channel has global users or not.
3669 * Added silc_server_channel_has_local function to check whether channel
3670 has locally connected clients on the channel.
3672 * The silc_server_remove_from_one_channel now checks whether the
3673 channel has global users or not after given client was removed from
3674 the channel. It also checks whether the channel has local clients
3675 on the channel anymore. If it does not have then the channel entry
3676 is removed as it is not needed anymore.
3678 * The silc_server_notify now checks on JOIN notify whether the joining
3679 client is one of locally connected or global. If it is global then
3680 the channel has now global users on the channel and that is marked
3681 to the channel entry. Also, it now saves the global client to
3682 global list who is joining and JOINs it to the channel. This is
3683 for normal server, that is.
3685 Changed silc_server_send_notify_on_channel,
3686 silc_server_packet_relay_to_channel and
3687 silc_server_packet_send_to_channel check if we are normal server
3688 and client has router set (ie. global client) do not send the
3689 message to that client, as it is already routed to our router.
3691 * Implemented LEAVE notify type handling in silc_server_notify
3694 * Tested LEAVE command in router environment successfully. Tested
3695 with two routers, two servers and two clients.
3699 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3701 * Implemented SIGNOFF notify type handling in silc_server_notify
3704 * silc_server_remove_id now removes the client entry from all channels
3705 it has joined and thusly sends SIGNOFF notify type.
3707 * Rewrote the NAMES list generation in server by removing two excess
3708 loops. The lists are created now inside one loop.
3710 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * silc_server_remove_channel_user checks now also global list
3713 for channel and client.
3715 * silc_server_new_channel_user checks now both local and global
3716 list for channel and client. Fixed a bug in client id decoding.
3717 Used to decode wrong buffer.
3719 * silc_server_channel_message checks now both local and global
3720 list for channel entry.
3722 * Tested channel joining (hence JOIN) in router environment
3723 successfully. Tested with two routers, two servers and two
3726 * Tested channel message sending in router environment successfully.
3728 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Added silc_server_save_channel_key into server.[ch] to save the
3731 received channel key in Channel Key payload processing. It is
3732 also used in JOIN command reply handling.
3734 Equivalent function silc_client_save_channel_key added into
3735 client.[ch] into client library.
3737 * Changed JOIN command reply to send information whether the channel
3738 was created or not (is existing already) and the channel key
3739 payload. Changed protocol specs accordingly.
3741 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3742 the request was sent by ID and not by nickname. Crashed on
3745 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3748 now correctly save the received data.
3750 * silc_server_free_sock_user_data now notifies routers in the
3751 network about entities leaving the network.
3753 At the same time implemented functions silc_server_remove_id
3754 and silc_server_send_remove_id to receive and send REMOVE_ID
3755 packets. The packet is used to notify routers in the network
3756 about leaving entities. The ID removed will become invalid in
3759 * Added function silc_idlist_del_server into server. Removes and
3760 free's server entry from ID list.
3762 * silc_server_private_message function now checks, if we are router,
3763 that the destination ID really is valid ID, naturally.
3765 * In router when NEW_ID packet is received (for new client) the
3766 hash of the Client ID is saved in the ID Cache but the
3767 client->nickname is set to NULL, instead of putting the hash
3770 IDENTIFY command now also checks that client->nickname must be
3771 valid. If it is not if will request the data from the server who
3772 owns the client. Added new function
3773 silc_server_command_identify_check.
3775 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3776 to set the command to already allocated Command Payload.
3778 * Tested private message sending in router environment with two
3779 routers, two servers and two clients. Fixed minor bugs and now
3782 * Fixed segfault from client's NAMES command. Used to crash if
3785 * Forwarded packets must not be routed even if it is not destined
3786 to the receiver. Changed server code comply with this.
3788 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Added `require_reverse_mapping' boolean value to ServerParams
3791 structure. If TRUE (not default) the server will require that
3792 the connecting host has fully qualified domain name.
3794 If the reverse mapping is not required and hostname could not be
3795 found the IP address is used as hostname.
3797 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Implemented version string checking to both client and server.
3800 The check is incomplete currently due to the abnormal version
3801 strings used in development version of SILC.
3803 * Changed all command functions in server to use the new
3806 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Changed char *data to unsigned char *data in ID Cache system to
3809 support binary data as ID Cache data. Changed code to support
3810 binary data in lib/silccore/idcache.c.
3812 * Renamed silc_server_packet_relay_command_reply to
3813 silc_server_command_reply as it is normal packet receiving
3814 function. Rewrote the function to accept command replys for
3815 servers and not only for clients.
3817 * Mark remote router always as registered server if we are connecting
3818 to it. Otherwise, commands sent by the router to us are ignored.
3820 * All ID List find routines now returns the ID Cache Entry pointer
3821 as well if requested.
3823 * WHOIS command works now in router environment, tested with two
3824 routers, two servers and two clients.
3826 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3827 in router environment (as it is almost equivalent to WHOIS) but
3828 hasn't been tested thoroughly. Added new functions:
3830 silc_server_command_identify_parse
3831 silc_server_command_identify_send_reply
3832 silc_server_command_identify_from_client
3833 silc_server_command_identify_from_server
3835 * Disabled route cache adding because adding two different ID's with
3836 same IP replaces the old cache entry thus giving wrong route.
3837 The entry->router->connection is always the fastest route anyway
3838 so route cache may not be needed. Of course, new routes maybe
3839 established after receiving the ID when the entry->router->connection
3840 might not be anymore the most optimal.
3842 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Add route cache for received ID for fast routing.
3846 * Added silc_server_packet_route to route received packet on router
3847 that is not destined to us.
3849 * Renamed silc_server_get_route to silc_server_route_get.
3851 * Added id_string and id_string_len fields into SilcServer to
3852 include encoded ServerID for fast comparing without excess
3853 encoding of the ID's.
3855 * Cleaned up WHOIS command on server side. Added following static
3858 silc_server_command_whois_parse
3859 silc_server_command_whois_check
3860 silc_server_command_whois_send_reply
3861 silc_server_command_whois_from_client
3862 silc_server_command_whois_from_server
3864 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3865 arguments in command replies. All command functions should be
3866 updated to use this macro.
3868 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Minor typo fixes on command reply handling on server.
3872 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Added silc_server_command_add_to_channel internal routine to add
3875 the client to the channel after router has created the channel and
3876 sent command reply to the server.
3878 * Added generic silc_server_send_command to send any command from
3881 * Use static buffer with ID rendering instead of duplicating data.
3883 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Fixed a channel user mode bug when joining to a channel server gave
3886 everybody channel founder rights, oops.
3888 * We mark ourselves as the router of the incoming server connection
3889 if we are router ourselves. This way we can check in some packet
3890 sending functions whether it is locally connected server. For
3891 incoming router connections we put NULL.
3893 * For router sending packets locally means now always sending the
3894 packet cell wide; to local clients and local servers. For normal
3895 server sending packet locally means sending it to only local
3898 * Fixed the JOIN command to really work in router environment. If the
3899 channel is created it is always created by the router. Router is
3900 also responsible of making the initial joining to the channel,
3901 sending JOIN notify to the sending server and distributing
3902 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3903 does not exist server doesn't do anything else but forward the
3904 command to the router which performs everything.
3906 * Added silc_server_send_channel_key function to send the Channel Key
3909 * Added silc_server_create_channel_key to create new channel key. The
3910 channel key is now re-generated everytime someone joins or leaves
3911 a channel, as protocol dictates. Note: channel->key_len is the
3914 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3917 packet_receive.[ch] to separate packet sending and receiving
3918 routines. The server.[ch] now includes everything else including
3919 actual packet processing (writing and reading data) and other
3922 Renamed silc_server_private_message_send_internal to
3923 silc_server_send_private_message. The routine is still though
3924 used only to relay private messages as server does not send
3925 private messages itself.
3927 Renamed silc_server_new_channel to silc_server_create_new_channel
3928 and added new function sicl_server_new_channel that handles the
3929 incoming New Channel packet. Added also new sending function
3930 silc_server_send_new_channel to send New Channel Payload.
3932 * Added new function silc_server_notify to process incoming notify
3933 packet to the server/router. Server may then relay the notify
3934 to clients if needed.
3936 * Added new function silc_server_new_channel_user to process incoming
3937 New Channel User packet. Router will redistribute the packet and
3938 send JOIN notify to its local clients and locally connected servers
3939 if needed. Normal server will send JOIN notify to its local client
3940 on same channel when received this packet. Added also corresponding
3941 sending function silc_server_send_new_channel_user to sent the
3944 * Added boolean route argument to send_notif_to_channel and
3945 packet_send_to_channel functions to attempt to route the packet
3946 if it is TRUE and send only locally if it is FALSE.
3948 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * silc_server_replace_id now broadcasts the received replace ID
3951 packet if it is not broadcast packet already. The router must
3952 broadcast to inform other routers about changed ID.
3954 * Added backpointer to server's router into SilcServer context in
3955 silcd/server_internal.h.
3957 * Fixed silc_server_packet_broadcast to send correct broadcast
3960 * The channel key is now distributed to the local client as soon
3961 as it is received from the router (in router environment) so that
3962 no other packet may be sent for the channel until client has
3965 * silc_server_remove_channel_user now broadcasts the received
3966 Remove Channel User packet if it is not broadcast packet already.
3967 The router must broadcast to inform other routers about removed
3970 * Added users field into SilcPacketContext that is a reference count
3971 of the context. One can increase the reference count by calling
3972 silc_packet_context_dup which is now changed to just increase the
3973 reference count instead of duplicating the data. The reference
3974 count is decresed by calling silc_packet_context_free that will
3975 free the data after the reference count hits zero.
3977 For now on the packet context and everything allocated into it
3978 (including the raw packet from network) must be freed by calling
3979 the new silc_packet_context_free function. Added also new function
3980 silc_packet_context_alloc that must be used now to allocate the
3981 context. This also means that if a routine is asynchronous from
3982 silc_[client/server]_packet_parse_type the packet context must
3983 be duplicated by calling silc_packet_context_dup. Otherwise it
3984 gets free'd after silc_[client/server]_packet_parse_type returns.
3985 Also, one must remember that if packet is duplicated then its
3986 reference count must be decresed by calling the free function as
3987 many times as it was duplicated.
3989 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3990 from both client and server.
3992 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Made joining to a channel working in router environment.
3996 * Cleaned up JOIN command on server side and create function
3997 silc_server_command_join_channel internal routine to make the
4000 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Changed silc_command_pending list to SilcDList. Also, added
4003 `ident' field to SilcServerCommandPending structure to identify
4004 the reply and to call correct callback.
4006 Added silc_server_command_pending_check function to replace the
4007 corresnponding macro. The silc_command_pending list is not
4010 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4011 to set identifier to previously allocated Command Payload. It
4012 is used to set identifier for command when resending Command
4015 * Added silc_command_payload_encode_payload to encode Command
4016 Payload buffer from SilcCommandPayload structure.
4018 * Added silc_argument_payload_encode_payload to encode Argument
4019 payload buffer from SilcArgumentPayload structure.
4021 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Changed WHOIS command to support router connection on server side.
4024 The whois request is always sent to router unless the server is
4025 standalone server. After server has received the reply from the
4026 router will it send the reply to the client.
4028 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4029 broadcast received broadcast packet. The function is used only
4030 by router. The broadcast packet is always sent to the router's
4033 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4034 render given ID to printable string, for log files for example.
4036 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Made basic router to router connections working. At least they
4039 can now connect to each other but nothing really works the way
4040 they are supposed - yet.
4042 * Added new initiator token to RouterConnection configuration
4043 file in silcd/serverconfig.[ch]. It is used to tell whether we
4044 are the initiator to the remote router or whether we'll expect
4045 the other end to connect.
4047 * Moved registering of listener task to silc_server_init, hence
4048 the server starts listenning as soon as it is run, even if it
4049 does not have connections to other routers. Let's see how well
4052 * Changed default connection retry timeouts for more suitable in
4055 * Removed cipher and such arguments from silc_idlist_add_client
4056 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4057 Added new function silc_idlist_add_data to add the keys and stuff
4060 * Added SilcIDListData structure and added it to SilcClientEntry
4061 and SilcServerEntry as their first field in the structure. This
4062 way we can explicitly cast the ID entries to the SilcIDListData
4063 structure and get common data for the entries. In past, we had
4064 to first check what type of connection it is and then cast it to
4065 correct ID entry type. Now, we can directly cast the opaque
4066 pointer to the SilcIDListData (no matter what ID entry it actually
4067 is) and get the data needed.
4069 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4072 in some circumstances even if threre were timeout tasks, though not
4073 IO tasks, but tasks anyway. Now fixed.
4075 * Defined SilcServerConnection structure to hold connection specific
4076 stuff about directly connected servers and routers. The definition
4077 is currently in silcd/server_internal.h. I thought about having
4078 a bit more important role fro this struct but for now it is used
4079 only when connecting to other server (or router actually).
4081 * Added connecting retry support in server when connecting to
4082 router(s). The retry feature implement exponential backoff
4083 algorithm. Also, added SilcServerParams structure to hold default
4084 parameters for server. For now, it include these retry settings
4085 and are hard coded. After server is moded to be as Silc Server
4086 Library this structure will be more important.
4088 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Changed client librarys channel->clients table to SilcList and
4091 changed code accordingly.
4093 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Changed client's channel table to SilcList and changed code
4096 accordingly. Also changed SilcChannelClientEntry to include back-
4097 pointer to the channel so that client entry can use that structure
4098 as list as well and we have fast cross-reference to the channel.
4099 This change dramatically decreased the complexity of channel
4100 handling with client entry and vice versa (removed one extra
4101 loop when searching for channel entry from many functions).
4103 * Changed server->sim from table to SilcDList and changed code
4106 * NAMES command can now be used from user interface. It will show
4107 the user list on the channel, neatly.
4109 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4110 Code now saves realname of the user if it becomes available.
4112 * Renamed configure.in to configure.in.pre and made ./prepare
4113 script to automatically add correct version string to
4114 configure.in which it creates from configure.in.pre.
4116 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * NAMES command reply now shows users mode with the nickname when
4121 * Moved silc_client_ch[u]mode[_char] functions from
4122 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4123 place sucks, they are utility functions and should be in some
4126 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4128 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4131 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Added TRQ (efficient deque and list library) into lib/trq. This is
4136 a very good list library that is currently used in the SILC. Defined
4137 SilcList API over the library because I didn't like the API very
4138 much. See lib/trq/silclist.h for the API and examples of how to
4139 use the API. Fixed various places in the code to use the new
4140 SilcList API. The SilcList is meant for lists that has a structure
4141 already defined as a list. It is not suitable to add just some
4142 context to the list (in TRQ, the context is the list actually).
4144 So, I defined SilcDList that can be used for the purpose where
4145 predefined list structure does not exit. This can be used as
4146 such list. Now some context just can be added to the SilcDList.
4147 Currently this list is not used in the SILC just yet, though there
4148 are a lot places where this can replace dynamically allocated
4149 tables and I will fix these places, later, to use SilcDList.
4150 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4151 and use TRQ internally).
4153 Also fixed some annoying warning messages that the original TRQ
4154 code generated. Also minor changes to TRQ's Makefile.in.
4156 * Added support for querying by Client ID to both WHOIS and
4157 IDENTIFY commands into server, as required by the protocol.
4159 * Removed method function pointers from SilcBuffer structure. They
4160 weren't used to anything and just increased the context size for
4161 no good reason. This change also made silc_buffer_alloc and
4162 silc_buffer_free functions inline functions.
4164 * Disabled command flooding detection support until it's fixed so
4165 that it accepts commands in but does not execute them more than once
4168 * Added silc_net_localhost(), to return local hostname, into
4169 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4170 that must be initialized before calling silc_client_init.
4172 * Added new function: silc_server_send_notify_on_channels to send
4173 notify messages to all channels client has joined. It is assured
4174 that the message is sent only once per client.
4176 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4177 lib/silcutil/silcutil.[ch] as silc_format function. The new
4178 function is generic and is used by server as well, not only by
4179 the logging routines.
4181 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4182 the provided version string was not acceptable. Added new function:
4183 silc_ske_check_version into lib/silcske/silcske.h. The function
4184 must be implemented by the application (client or server) and it
4185 does not reside in the SKE library. The function checks the version
4186 string remote end sent.
4188 * Added back pointers (to opaque context and to SilcSocketConnection)
4189 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4191 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4192 duplicate packet context structure.
4194 * Changed `notify' client operation to send same arguments as client
4195 receives from server except for ID's. ID's are mapped to correct
4196 ID entry and that is returned. Also, if channel entry is not sent
4197 by server but the notify is for channel the channel entry is sent
4198 to application (otherwise application doesn't know that it is for
4199 channel (library gets it from packet's Destination ID)).
4201 * Added silc_client_remove_from_channels into client library to
4202 remove a client from all channels it has joined to. Used when
4203 received SIGNOFF notify from server. Added also new function
4204 silc_client_replace_from_channels to replace old ID entry with
4205 new ID entry on all channels. Used when received NICK_CHANGE
4208 * Fixed ID Cache list handling in silc_idlist_get_client in
4209 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4210 to get (or query) client by ID.
4212 * Updated TODO list.
4214 * Added connection authentication status message defined by the
4215 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4216 support for these into the code in client and server side.
4218 * Added generic function silc_client_send_command to send any command
4219 with variable argument list. Application should use this function
4220 to send commands if the command functions provided by the library
4221 does not suite for the application's user interface needs.
4223 * Added new `failure' client operation. Application is notified about
4224 received failure packet if client is executing a protocol. In this
4225 case the protocol's execution has failed.
4227 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4228 is required by the protocol.
4230 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4231 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4234 * Added status flag to SilcSKE object to indicate realtime status
4235 of the SKE protocol.
4237 * Application receives now exactly same command reply arguments as
4238 the library receives from server. However, if ID is received the
4239 corresponding ID entry is returned to the application (eg. Client
4240 ID is mapped to correct SilcClientEntry entry and that is returned).
4241 Changed command_reply client operation due to this change.
4243 * Changed all ID's in commands and in command replys as ID Payloads.
4244 Change affected both client and server side codes.
4246 All ID's sent in SILC network (with execption of ID's in SILC
4247 Packet header) are sent in ID Payload to support variable length
4250 * Server now notifies nick changes and notifies all clients on
4251 the channels about the new nickname (about the new Client ID,
4254 * Implemented CMODE command to change channel modes. Supports all
4255 channel modes defined by the protocol specs except ban and invite
4256 lists. (Also, private channel key mode is supported but support for
4257 setting private channel key in client is missing, thus, this mode
4258 has no effect on client side (except that server requires that the
4259 client uses private channel key and normal channel traffic does not
4262 Also, invite mode works per se, but INVITE command does not work
4263 yet correctly, so you can set channel as invite only channel but
4264 inviting clients to the channel does not work (it is yet to be
4265 thought what's the best way to do it).
4267 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4268 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4269 Implemented CUMODE command to change user's mode on the channel.
4270 Supports all modes defined by the protocol specs.
4272 * Added NAMES command reply to return users modes on the channel.
4274 * Removed unnecessary and slow ciphers from lib/silccrypt.
4276 * Set SO_KEEPALIVE option to connection sockets by default.
4278 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4280 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4281 redefined the Notify Payload into protocol specs.
4283 * Added silc_id_payload_parse_id to get ID directly from raw
4286 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4289 accept searching by Client ID as well.
4291 * Added support for LEAVE and SIGNOFF notify types in client library.
4293 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4294 to parse ID Payload from raw data.
4296 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Added flags parameter into silc_ske_assemble_security_properties
4299 function in lib/silcske/silcske.[ch].
4301 * Changed notify client operation to fit better for notify messages
4302 sent by server. The notify payload received from server is now
4303 passed to the application (after parsing it to SilcNotifyPayload).
4304 It is application's responsibility to retrieve the arguments
4305 from the payload and show the message the way it wants. The message
4306 sent by server is implementation specific.
4308 * Changed public keys to comply with the protocol specification.
4309 Old public keys are not supported anymore and are not compatible.
4311 * Removed nickname from Channel Payload as the latest draft removed
4312 it. The client must resolve the nickname from the NAMES command
4313 reply received when it joined the channel.
4315 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4317 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Fixed some errors in protocol specification drafts.
4321 * Created lib/silccore/silcnotify.c to implement Notify Payload
4322 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4323 generic payloads described by protocol specifications. The file
4324 includes implementations for ID Payload and Argument Payload.
4326 * Changed Command Payload implementation to use the new Argument
4327 Payload. Changed command_xxxx_payload to command_payload_xxxx
4328 to comply with SILC coding conventions.
4330 * Added suppport for Argument Payload handling in Notify Payload
4331 implementation as protocol requires it. Added the new support
4332 into server and client lib as well.
4334 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Added support for multiple nicknames on same channel. [n] is
4337 added locally to the nickname if there are more than one same
4338 nicknames on the channel.
4340 * Server now sends all nicknames that matched WHOIS request.
4341 Client also shows the list received from server.
4343 * Added TOPIC command to client side. User can now set and show
4344 current topic on channel.
4346 * Added MOTD command to client and server. Also, server sends the
4347 motd when client connects to the server.
4349 * Changed version strings to comply ISO 8601.
4351 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Fixed protocol error handling in client library. It should now
4354 cope even if the SKE fails for some reason.
4356 * Made new protocol specification drafts for submitting to IETF.
4358 * Implemented TOPIC command to server in silcd/command.c.
4360 * Added two new notify types into lib/silccore/silcnotify.h:
4361 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4362 notify nickname change and topic setting/change on a channel.
4364 * API change of command_reply operation in client library. The
4365 application gets now the status type received from server as well.
4367 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4371 * Cras fixed and optimized the packet handling even further and
4372 it should work now. Minor change to the prototype of function
4373 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4375 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Added new function into lib/silcutil/silcschedule.[ch]:
4378 silc_schedule_with_fd to select() a specified fd. The function
4379 returns after timeout expires or data arrives or goes. The
4380 function is used by packet routines to wait that all data is
4381 received from network.
4383 * Fixed data reading from network in lib/silccore/silcpacket.c.
4384 The code now assures that all data is read from the fd and then
4385 continues packet processing. This was a bug fix since the code
4386 used to drop some data in some circumstances.
4388 * Added new function into lib/silcclient/client.[ch]:
4389 silc_client_start_key_exchange to start key exchange after
4390 connection has been established to server. The code internally
4391 now uses this funtion but its main purpose was to provide it
4392 for applications that perform their own connecting. After
4393 application has created a connection it merely calls this
4394 function to start the key exchange between client and server.
4395 The library takes care of everything else after that.
4397 Updated also lib/silcclient/README to explain the usage of
4400 * Do not send to application information that connection has
4401 been established. Application gets notified it by connect
4404 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Applied cras's patch to add silc_schedule_one function. The
4407 function runs scheduler once and returns.
4409 * Fixed the scheduler after cras messed it up. The timeout
4410 handling works now as it's supposed to work.
4412 * Added into lib/silccore/ silcnotify.h to include notify
4413 message types support. Changed silc_server_send_notify*
4414 functions, in server.[ch], to support those new notify types.
4415 Added the support for the notify types into client library,
4416 as well. Added new notify client operation into ops.h in
4419 * Changed silc_server_packet_send_to_channel to send normal
4420 packets instead of just channel message packets. The function
4421 is now used to send the notify packets to channels. It is not
4422 used to send channel message packets anymore, as server never
4425 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4426 va_arg()s as it seems to require it nowadays. I guess, if SILC
4427 is compiled with older va_arg() the new code should work anyway.
4429 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Splitted core library. Core library (lib/silccore) includes
4432 now only SILC protocol specific core (and common) components.
4433 Created new utility library (lib/silcutil) that includes more
4434 generic purpose stuff. The stuff for util library was taken
4435 from the old core library. This was minor and easy split.
4437 * Created SILC Client Library (lib/silcclient) that includes
4438 implementation of the SILC client without user interface. This
4439 was major move from silc/ directory. The code has been changed
4440 so that it is transparent towards the user interface. The
4441 silc/ directory includes now the same user interface as before
4442 and it uses the new client library. Read lib/silcclient/README.
4443 Basicly, the client library performs everything else related
4444 to SILC except user interface handling. Also, configuration
4445 files are considered to be part of user interface and library
4446 does not handle them.
4448 This change also changed a lot of structures, function naming etc.
4449 Most important change was that SilcClientWindow object was
4450 renamed to SilcClientConnection in the client library. Created
4451 also new file lib/silcclient/ops.h. Also added new files
4452 silc/local_command.[ch] and silc/client_ops.[ch].
4454 All these changes were made to make it easier for user interface
4455 designers to create what ever user interface for the SILC client
4458 It is also expected that the server will be moved to lib
4459 directory as well and SILC Server Library will be created;
4460 sometimes in the future.
4462 * Removed Local commands from lib/silccore/silccommand.h as
4463 they are application specific and new client library does not
4464 handle any of those anymore.
4466 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4467 old client implementation in silc/.
4469 * Added support for callback functions in SILC_LOG_* macros.
4470 Application can now set its own callbacks that will be called
4471 instead of using the default functions that will always print
4472 the debug messages to stderr (or stdout). Also, debugging can
4473 now be disabled by setting silc_debug to FALSE and re-enabled by
4474 setting it to TRUE. Note, that logging will still work even
4475 if debugging is disabled.
4477 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4478 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4479 silc_log_reset_debug_callbacks.
4481 * To enable debugging in silc client one must give now -d
4482 option on command line.
4484 * Changed silc_schedule_init to automatically allocate task queues
4485 if they are not allocated before calling it.
4487 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Added GMP 3.1 into math library.
4491 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4494 a channel in SILC network. The packet is used by servers and
4495 routers to notify other routers that user has left a channel.
4496 This little feature was missing until now. Added the feature
4497 to protocol specification as well.
4499 Added functions: silc_server_send_remove_channel_user and
4500 silc_server_remove_channel_user into server.[ch].
4502 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4503 lib/silccore/silcpacket.h. However, they are not implemented
4506 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Fixed joining to a channel and sending channel messages
4509 between server and router. The channel message sending should
4510 now work inside a cell.
4512 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Fixed the private message sending between server and router.
4515 The private message sending should now work inside a cell.
4517 * Added silc_server_replace_id into server.[ch] to replace
4518 existing ID in the SILC network.
4520 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4521 and silc_idlist_replace_server_id into idlist.[ch] in server.
4523 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Fixed the server to server connections. Server can again now
4526 connect to router. Router to router connections probably does
4529 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Added dynamic protocol registering support. Now protocols can
4532 registered and unregistered on the fly. Patch by cras.
4534 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Added lib/contrib directory to hold routines that some platforms
4537 don't have but are needed by SILC.
4539 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4540 into lin/contrib to provide getopt() and getopt_long() for
4541 those who don't have it.
4543 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Added AWAY command to client. When away message is set and
4546 client receives a private message packet the client automatically
4547 replies to the sender with the away message.
4549 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4550 bug seemed to be the cause of recent problems when compiling
4553 * Added version detection support to SKE protocol specification
4554 and added the new changes to the SKE implementation as well.
4555 There were other minor changes in the SKE protocol as well.
4557 Many changes in lib/silcske/silcske.[ch] and in
4558 lib/silcske/payload.[ch].
4560 * Added ^U functionality, clear input line. Patch from cras.
4562 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Mainly small bugfixes on core library. Fixed some debugging
4565 logging and buffer overflow in silclog.c.
4567 * Updated config.sub and config.guess on the distribution tree.
4569 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added command lagging support in server. Client may execute
4572 commands now only once in two seconds.
4574 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Optimized packet reception. MAC computation and checking is now
4577 also more optimized. A lot previously duplicated code is now
4578 used as generic by both client and server.
4580 * Fixed key pair generation in clientutil.c
4582 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Added into lib/silccore/silcbufutil.[ch] new function;
4585 silc_buffer_realloc.
4587 * Moved generic packet sending/encryption functions to
4588 lib/silccore/silcpacket.[ch] from client and server. Some
4589 rewriting of the functions.
4591 * Moved all generic packet reception/decryption functions to
4592 lib/silccore/silcpacket.[ch] from client and server. The
4593 packet processing is now much cleaner in both client and server.
4594 These were major changes in both client and server.
4596 * Created many common functions in server to do packet sending.
4597 Previously code were duplicated a lot, this has been removed
4600 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Rewrote major parts of the ID cache system. Don't know
4603 whether it is better now or not but at least the API is more
4606 * Major rewrite on ID cache stuff on client because of the ID
4607 cache API changes. Added idlist.c to client.
4609 * Also major rewrite on ID cache stuff on server as well.
4610 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4611 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4612 in hand, instead they are all put into the ID cache system now.
4613 All server_idlist_* routines uses ID cache now instead of
4614 traversing its own lists (those lists does not exist anymore).
4615 SilcIDList though still exists. Also, SilcXXXEntry's are
4618 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Finally made the SKE implementation compliant to the protocol
4621 specification. All mp integers are now binary encoded as
4622 opposed being HEX encoded.
4624 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4627 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4628 functions: silc_[encode/decode]_pem. Also added function
4629 silc_encode_pem_file to PEM encode with newlines ('\n') for
4632 * SILC public keys are now encoded either PEM or binary. Same
4633 option is for private keys as well. By default private keys
4634 are binary encoded and public keys PEM encoded. Silly HEX
4635 encoding were removed.
4637 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4638 function to create fingerprints.
4640 * Fixed a bug in SHA1; does not change the original data anymore.
4642 * Partly implemented INFO command on client and server side.
4643 Fixed CLEAR command. Changes to SERVER command; show current
4644 server(s) when giving command without arguments. Added
4645 VERSION command to client.
4647 * Added check to server that unregistered connections cannot
4648 execute commands (unless it is specificly allowed).
4650 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Fixed screen refresh.
4654 * Fixed channel joining bug from client. On some circumstances
4655 client tried to join to a channel it had already joined.
4657 * Added public key verification process into client's protocol.c.
4658 The client now verifies the public key from user and saves
4659 it into ~./silc/serverkeys/ directory.
4661 Added into: clientutil.[ch]: silc_client_verify_server_key.
4663 * Changed SKE protocol's silc_ske_initiator_finish function
4664 to accept callback function that verifies the received public
4665 key. Removed old silc_ske_verify_public_key function.
4667 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4670 silc_pkcs_private_key[_data]_set.
4672 * Made the password and public authentication more cleaner in
4673 server's protocol.c.
4675 * Removed historic and obsolete protocol `channel_auth' from
4676 both client and server.
4678 * Removed wrong way of sending command status messages from
4679 server to client in server's command.c. The old way violated
4680 protocol specification.
4682 Changes to silccore/silccommand.[ch]: removed
4683 silc_command_encode_status_payload -> not needed anymore,
4684 changed silc_command_encode_payload_va to accept extra
4685 argument on variable argument list. The argument type must
4686 now be provided to the function. Also, added new function:
4687 silc_command_encode_reply_payload_va which is same as
4688 normal command_encode_payload_va except command status type
4689 is provided as extra argument.
4691 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added ~./silc directory handling. The directory includes the
4694 public and private keys for the client.
4696 Added silc_client_check_silc_dir, silc_client_create_identifier
4697 and silc_client_load_keys.
4699 * Implemented SILC protocol compliant public key. Added public
4700 and private key saving to and loading from files.
4702 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4703 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4704 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4705 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4706 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4708 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4709 silc_pkcs_load_[public/private]_key.
4711 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Added silc_server_get_route (route.[ch]) to get connection
4714 data for the fastest route for given ID.
4716 * Implemented INVITE command on client and server. The command
4717 were re-defined in the SILC Protocol Specification and the
4718 implementation now complies with the specification.
4720 * Implemented PING command on client and server.
4722 * Implemented NAMES command on client and server. The server side
4723 supports currently only normal server not router server yet.
4724 Some changes to NAMES definition in SILC protocol specification.
4726 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Implemented LEAVE command on client and server.
4730 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4731 again. This change was made to the protocol as well. Server
4732 should not violate the protocol specification anymore.
4734 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4737 was tested. SOCKS4 was not but should work anyway.
