1 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed a channel key regeneration bug. It registered new
4 timeout tasks exponentially until all system resources were
5 used. Affected file silcd/server.c.
7 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Added the SILC Document generator to the scripts/silcdoc.
10 It can be used to generate the Toolkit Reference Manual out
11 of the source tree. Internally it will also use the RoboDoc
12 generator now imported in util/robodoc.
14 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Added couple of return's in rekey protocol if error orccurred
17 during the protocol. The execution must be terminated.
18 Affected file silcd/protocol.c. Also, terminate the protocol
21 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
23 * The client's Client ID was created initally from the wrong
24 nickname (it could have been in format nick@host) in the
25 silc_server_new_client. Affected file silcd/packet_receive.c
27 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

30 if client could not be added to ID cache. Affected files
31 silcd/packet_receive.c and silcd/server.c.
33 * When client's sock->user_data is freed, NULL also the
34 client->router and client->connection pointers. Added check
35 for these pointers being NULL to various places around the
36 code. Affected file silcd/server.c.
38 * Added client->data.registered == TRUE checks to various
39 places around the code to assure that unregistered client's
40 are not handled when it is not allowed. Affected file
43 * Added `bool registered' fields to all
44 silc_idlist_[server|client]_get_* routines to indicate whether
45 the fetched client needs to be registered or not. Affected
46 file silcd/idlist.[ch].
48 * Add your own entry as registered to the ID cache in the
49 server. Affected file server.c.
51 * Fixed a bug in silc_server_new_server. The SilcServer was
52 set as the new server's context instead of SilcServerEntry.
53 This naturally caused some weird bugs.
55 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Do not delete the channel rekey task when adding it
58 for in silc_server_create_channel_key.
60 * Changed the silc_server_create_channel_key to return
61 TRUE or FALSE to indicate the success of the channel key
64 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
66 * Fixed MSVC++ project files and added missing files to
67 Makefiles under win32/.

71 * Do not add TCP_NODELAY flag if the operating system
72 does not have it defined. Affected files are
73 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
75 * Fixed buffer overflow from Irssi SILC Client. Affected
76 file irssi/src/fe-common/core/themes.c.
78 * Fixed double free in client library in the file
79 lib/silcclient/client.c when disconnecting from server.
81 * Applied double free patch from cras to Irssi SILC client.
82 Affected files irssi/src/core/[modules/expandos].c
84 * Fixed the disconnection handling to Irssi SILC Client.
85 The application must call silc_client_close_connection
86 in ops->connect client operation in case of failure of
87 the connection. Affected file is
88 irssi/src/silc/core/client_ops.c.
90 * Do not set sock->protocol to NULL in the function
91 silc_client_close_connection after executing the protocol's
92 final callback since the sock might not be valid anymore.
93 Affected file lib/silcclient/client.c.
95 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Do not enable SILC_THREADS if the linking with libpthread
98 did not happen. Affected file configure.in.pre.
100 * Added notion to protocol specification that server must
101 verify the sent authentication payload with CMODE when
102 setting the channel founder key. Implemented it to the
103 server. Affected file silcd/command.c.
105 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
107 * Added _EXTRA_DIST SILC distribution variable to the
108 distributions file. It is used to conditionally add extra
109 files or directories to the specific distribution. Affected
110 files ./prepare, Makefile.am.pre and distributions.
112 Removed the `_' from the start of the distribution names.
115 * Added README.WIN32 for instructions to compile the Toolkit
118 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Fixed a double free in disconnection in the server. Affected
121 file is silcd/server.c.
123 * Fixed the lib/silcske/groups.c to work now also with GMP
124 MP library. The string conversion did not work when using
125 specific base and the base is indicated in the string as well.
127 * Created win32/ directory which now includes MSVC++ specific
128 stuff so that toolkit (DLLs) may be compiled with MSVC++.
129 It will appear only in the toolkit distribution
131 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
133 * Changed the key material distribution function in case when
134 the hash output is too short. The data is now concatenated
135 a bit differently than it used to. Made the change to the
136 SKE protocol specification.
138 * Added better GMP detection to configure.in.pre. A patch
141 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Fixed a minor bug in SKE that might cause some problem on
144 some platforms. Affected file lib/silcske/silcske.c.
146 * Added the cookie checking for initiator in the SKE. It checks
147 that the responder returns the sent cookie unmodified. The
148 affected file is lib/silcske/silcske.c. Added new SKE
149 error type INVALID_COOKIE that can be sent during the
150 negotiation. Fixed some memory leaks as well.
152 * Added the "invalid cookie" error message to Irssi SILC client's
155 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Added `task_max' field to the SilcClientParams to indicate
158 the maximum tasks the scheduler can handle. If set to zero,
159 default values are used. Affected file lib/silcclient/silcapi.h.
161 * Fixed memory leaks in silc_client_close_connection. Affected
162 file lib/silcclient/client.c.
164 * Added silc_client_del_client_entry to client library to free
165 all memory of given client entry. Affected file is
166 lib/silcclient/idlist.[ch].
168 * Added new functions silc_client_del_channel and
169 silc_client_del_server to delete channel and server entries.
170 Affected file lib/silcclient/[silcapi.h/idlist.c].
172 * Removed silc_client_del_client_by_id from silcapi.h.
174 * Fixed the INFO command to return the server's own info
175 correctly when querying by Server ID. Affected file is
178 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
180 * Removed the non-blocking settings in WIN32 code in the
181 silc_sock_[read/write] and added SleepEx instead. Affected
182 file lib/silcutil/win32/silcwin32sockconn.c. The availability
183 of input data is now checked with FIONREAD and ioctlsocket.
185 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
187 * Call silc_schedule_task_del_by_context in the
188 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
189 Affected file lib/silccore/silcprotocol.c.
191 * Call silc_protocol_cancel for active protocols in the
192 silc_server_close_connection if the funtion
193 silc_server_free_sock_user_data has not been called.
194 Affected file silcd/server.c.
196 * Generic tasks cannot be deleted using the del_by_fd
197 task deleting function since generic tasks does not match
198 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
200 * Added a notion to SILCOPER help file that the SILCOPER works
201 only on router server, not on normal server.
203 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
205 * Added for WIN32 support for the new scheduler as well.
206 Affected file lib/silcutil/win32/silcwin32schedule.c.
208 * Fixed the SHA1 implementation to work on various platforms.
210 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
212 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
213 API. It is part of the scheduler now. Everything else is
214 as previously but some functions has changed their names.
215 Checkout the lib/silcutil/silcschedule.h for the interface.
216 Updated all applications to use the new interface. Affected
217 files are lib/silcutil/silcschedule.[ch].
219 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
221 * Found a bug in the SKE implementation. The HASH value,
222 specified by the protocol, was not computed correctly. The
223 public key of the responder was not added to the computation
224 even though it is mandatory. Affected file lib/silcske/silcske.c.
225 This unfortunately causes incompatibilities with older
228 * Added WIN32 specific network init and uninit functions:
229 silc_net_win32_init and silc_net_win32_uninit to init and uninit
230 the Winsock2. Affected file lib/silcutil/silcnet.h and
231 lib/silcutil/win32/silcwin32net.c.
233 * Set the socket always to nonblocking mode on WIN32 after
234 reading data or writing data. Affected file is
235 lib/silcutil/win32/silcwin32sockconn.c.
237 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
239 * Fixed various compilation problems under WIN32. Affected
240 files lib/silcutil/win32/silcwin32thread.c and
241 lib/silcutil/win32/silcwin32schedule.c.
243 * Removed all _internal.h #includes from public header
244 files. Internal headers must never be included from
247 Removed also the lib/silcske/payload_internal.h file.
249 * All include files that may be needed (public and some others
250 included by the public headers) by application developers are
251 now copied to the ./includes directory. It does not copy any
252 internal headers. Affected file Makefile.defines.pre and all
253 Makefile.am's under lib/ and subdirs.
255 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
257 * Do not change the ~/.silc directory's permissions automatically.
258 Affected file irssi/src/silc/core/clientutil.c.
260 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Do not cancel the protocol in silc_server_close_connection
263 it might cause recursion. Now cancelled in the function
264 silc_server_free_sock_user_data. Affected file silcd/server.c.
266 * Fixed the silc_server_remove_clients_by_server to regenerate
267 the channel keys correctly finally. Added also new function
268 silc_server_remove_clients_channels to actually do it.
269 Affected file silcd/server.c.
271 * Fixed the silc_server_new_channel to not crash by giving
272 wrong router to the new channel. Affected file is
273 silcd/packet_receive.c.
275 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
278 which is given as argument to the silc_client_alloc now.
279 It can be used to configure the client and set various parameters
280 that affect the function of the client.
282 * The USERS command in server did not check whether the channel
283 is private or secret. Affected file silcd/command.c.
285 * Added new argument to the USERS command in protocol specification.
286 The USERS command now can take the channel name as argument
287 as well. Added support for this in client and server and
288 updated the protocol specs.
290 * Completed the GETKEY command in client. It can be now used
291 to fetch also servers public key not only some clients.
292 Affected files lib/silcclient/command[_reply].c.
294 * Added silc_client_get_server to return server entry by the
295 server name. Affected files lib/silcclient/silcapi.h and
298 * Redefined the IDENTIFY command in protocol specification to be
299 more generic. It now can be used to query information about
300 any entity in the SILC Network, including clients, servers and
301 channels. The query may be based either the entity's name
302 or the ID. Added support for this in both client and server.
304 Affected files silcd/command.c and lib/silcclient/command.c
307 * Optimized the WHOIS and WHOWAS commands in the server. Removed
308 the _from_client and _from_server functions. Affected file
311 * Added silc_client_get_channel_by_id_resolve to the file
312 lib/silcclient/silcapi.h to resolve channel information by
313 its ID. Added also silc_client_get_channel_by_id that
314 does not resolve it from the server.
316 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Added SilcServerEntry context into the client library
319 to represent one server. The INFO command now allocates
320 these to save the resolved server info. For now on the
321 client library will also keep information about servers,
322 connected and resolved with INFO.
324 The INFO command now allocates the SilcServerEntry context
325 and saves the server info there. The COMMAND_REPLY in
326 the INFO now returns the parameters to application in
327 same order as defined in the protocol specification.
329 The entries are cached in the client->server_cache.
331 * The INFO command is now issued after received the Client ID
332 from the server. Affected file lib/silcclient/client.c.
334 * The CMODE_CHANGE notify may now return also an SilcServerEntry
335 to the application as the mode changer might be server.
336 It is guaranteed that NULL is not returned anymore to the
337 application. Affected file lib/silcclient/client_notify.c.
339 The ID Type is now also passed to the application so that
340 it can check whether the returned entry is SilcClientEntry
343 Added new function silc_client_get_server_by_id to return
344 the server entry by ID. Affected files are the
345 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
347 * Do not create the channel in the Irssi SILC Client when issuing
348 the JOIN command but when received the sucessful JOIN command
349 reply. Otherwise the channel might get created even though we
350 could not join it. The Affected file is
351 irssi/src/silc/core/[silc-channels.c/client_ops.c].
353 * Fixed a channel joining bug in router. The router must also
354 check the channel modes, invite and ban lists etc. when serving
355 the JOIN command sent by normal server. Affected file is
356 silcd/command.c. The router now resolves the client's
357 information from the server who sent the JOIN command if it
358 does not know it, and processes the JOIN command only after
361 * Changed the SilcCommandCb to take new argument; void *context2.
362 Affected file lib/silccore/silccommand.h
364 The second argument in the command callbacks in the server now
365 includes the SilcServerCommandReplyContext if the command was
366 called as pending command callback from the command reply.
367 Otherwise it is NULL. When called as pending the status of the
368 command reply will be checked and if it was erronous the
369 error will be sent to the original sender of the command.
370 This way the client always receives the error messages even
371 though the server was actually the one who received the error
372 when it resent the command to router, for example. Affected
373 files silcd/command[_reply].[ch].
375 * Fixed sending WHOWAS command's error message to client if
376 the requested client could not be found. It was missing.
379 * Changed the CMODE and CUMODE commands reply arguments in the
380 protocol specification. The Channel ID is now sent in both
381 of the commands to identify the channel. Implemented this
382 new feature to the client and server. Affected files
383 lib/silcclient/command_reply.c and silcd/command.c.
385 * Made better checks for invite and ban lists in the JOIN
386 command in server. Affected file silcd/command.c.
388 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
390 * The server now performs the incoming host IP/DNS lookup
391 using the silc_socket_host_lookup and thus does not block
392 the server anymore. Affected file silcd/server.c.
394 * Completed the multi-thread support for SILC Scheduler in
395 the lib/silcutil/silcschedule.c.
397 * Fixed the configure.in.pre to detect the pthread correctly
400 * Fixed a deadlock in silc_task_queue_wakeup in the file
401 lib/silcutil/silctask.c.
403 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Added new function silc_schedule_wakeup that is used in
406 multi-threaded environment to wakeup the main thread's
407 schduler. It needs to be used when a thread adds a new task
408 or removes a task from task queues. After waking up, the
409 scheduler will detect the task queue changes. If threads
410 support is not compiled in this function has no effect.
411 Implemented the wakeup mechanism to both Unix and WIN32
412 systems. Affected files are lib/silcutil/silcschedule.[ch],
413 lib/silcutil/unix/silcunixschedule.c and the
414 lib/silcutil/win32/silcwin32schedule.c.
416 * Added new function silc_task_queue_wakeup to wakeup the
417 scheduler by the specified task queue. Affected file
418 lib/silcutil/silctask.[ch].
420 * The silc_socket_host_lookup_start now wakes up the scheduler
421 after adding the timeout task. Affected file is
422 lib/silcutil/silcsockconn.c.
424 * The silc_socket_host_lookup is synchronous now if the threads
425 support is not compiled in. However, the callback is still
426 called asyncronously through the scheduler, anyway. Affected
427 file lib/silcutil/silcsockconn.c.
429 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Added new function silc_socket_host_lookup to perform
432 asynchronous IP and FQDN lookups for the socket connection.
433 Affected files lib/silcutil/silcsockconn.[ch].
435 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
437 * Added SILC_MUTEX_DEFINE to define the mutex on environments
438 that may or may not compile the mutex support in.
440 Changed the silc_mutex_alloc interface. It allocates the
441 mutex now to the sent pointer and returns TRUE or FALSE.
443 Affected file lib/silcutil/silcmutex.h.
445 * Wrote the SILC Task Queue interface to support multi-threads.
446 Affected file lib/silcutil/silctask.[ch].
448 * Wrote the SILC Scheduler to support multi-threads. Affected
449 file lib/silcutil/silcschedule.c.
451 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
453 * Implemented the SILC Mutex API and SILC Thread API for WIN32
454 in lib/silcutil/win32/.
456 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Defined SILC Mutex API and SILC Thread API and implemented
459 them for Unix. Affected files are
460 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
461 lib/silcutil/unix/silcunixmutex.c and
462 lib/silcutil/unix/silcunixthread.c.
464 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
466 * Fixed the silc_server_remove_clients_by_server's channel
467 key re-generation. The hash table handling was incorrect
468 and would not work with many channels. Affected file is
471 * Fixed some memory leaks around the server code.
473 * Rewrote the silc_server_get_users_on_channel to support IPv6
474 based Client ID's. Affected file silcd/server.c.
476 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
477 specification. However, a separate document must be written
478 to define the detailed signing procedure and the payload
479 associated with the flag. Defined the flag to the
480 lib/silccore/silcchannel.h as well.
482 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
484 * Changed the dynamic tables to static size tables in the
485 lib/silccrypt/silchmac.c.
487 * Removed GCC dependencies from the code. A patch by cras.
489 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
491 * Do not show the error "Error receiving packet bla bla"
492 in server if it really was not an error (-2 means that reading
493 is pending). Affected file silcd/server.c.
495 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
497 * Fixed a possible crash in silc_server_remove_clients_by_server
498 in silcd/server.c. Fixed there also some memory leaks.
500 * Fixed the silc_idlist_replace_client_id. It could replace
501 wrong key in the hash table. Affected file silcd/idlist.c.
503 * Do not check whether there are global users on the channel
504 if the channel->global_users is FALSE. Affected functions
505 silc_server_remove_from_one_channel and
506 silc_server_remove_from_channels in silcd/server.c. Also,
507 do not check if the removed client is local as we can be
508 sure that global client was not removed from the channel
509 and checking for global users is not needed.
511 * The silc_server_remove_clients_by_server now re-generates
512 the channel keys correctly for those channels that had
513 clients removed from them. Affected file silcd/server.c.
515 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Found the reason of random crashes in the server. We weren't
518 ignoring the SIGPIPE signal (which can be sent in write())
519 and it crashed the server. Affected file silcd/silcd.c.
521 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
523 * Assure that sock->user_data is not NULL in the function
524 silc_server_packet_send in silcd/packet_send.c.
526 * Disconnect the remote connection if it could not be added
527 to any ID lists in the server. The affected file is
530 * Check in silc_server_packet_send[_real/dest] that the
531 socket is not disconnecting and ignore the data if it is.
532 Affected file silcd/packet_send.c.
534 * Define inline to __inline on native WIN32 compilation.
535 Affected file includes/silcwin32.h.
537 * Added some explicit type casts for inline code since MSVC
538 require them. Affected files lib/silcutil/silcbuffer.h,
539 lib/trq/silcdlist.h and lib/trq/silclist.h.
541 * Print warning in log files from now on if the packet
542 decryption fails. Affected file silcd/server.c.
544 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Changed the `say' client operation's interface to accept
547 new `type' argument to indicate the type of the message sent
548 by the library. The application may filter the library's
549 messages according the type. The affected file is the
550 lib/silcclient/silcapi.h.
552 * Added two new functions to lib/silcclient/silcapi.h:
553 silc_client_del_client and silc_client_del_client_by_id.
554 Affected file lib/silcclient/idlist.c.
556 * Moved the clientincludes.h from includes/ to silc/ and
557 serverincludes.h from includes/ to silcd/.
559 * The modes for the CMODE and CUMODE are now passed as
560 uint32 for application with COMMAND_REPLY. The affected
561 file is lib/silcclient/command_reply.c.
563 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
565 * /WHOIS without arguments shows client's own information.
566 Affected file lib/silcclient/command.c.
568 * Changed PING to not accept any arguments. The specs
569 says that client can ping only the connected server so
570 requiring an argument is not needed. Affected file is
571 lib/silcclient/command.c.
573 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
575 * Fixed a fatal bug in private message sending and reception
576 encryption and decryption when using private message keys.
577 The implementation was incorrect and did not follow the
578 specification. It causd that some of the message were
579 lost since it did not use the sending and receiving keys
580 as the protocol suggests. This has been fixed and will cause
581 incompatibilities with older clients when sending private
582 message encrypted with private message keys. Affected files
583 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
584 and various other in Irssi SILC Client.
586 Added `responder' boolean argument to the functions
587 silc_client_add_private_message_key[_ske] to indicate when
588 the key is added as responder or initiator of the key
591 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
593 * Removed the silc_ske_check_version function and created
594 a SilcSKECheckVersion callback. Added also a function
595 silc_ske_set_callbacks that is now used to set all SKE
596 callbacks. The callback functions are not given to
597 the SKE functions anymore, but this function is used to
600 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
602 * Added `silc_version' argument to the silc_client_alloc
603 to define the version of the application for the library.
604 The library will use the version string to compare it
605 against the remote host's (usually a server) version
606 string. Affected file lib/silcclient/silcapi.h
608 * Added the KE protocol context to Key Agreement context
609 in client library so that we can abort the SKE if it
610 is in process when we get timeout. Affected file is
611 lib/silcclient/client_keyagr.c.
613 * Do not resolve the client ID forever if it returns in the
614 first time that such client does not exist. This was done
615 for example with private message. Affected file is
616 lib/silcclient/client_prvmsg.c.
618 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Do not add regex.h for WIN32. The affected file
621 includes/silcincludes.h.
623 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
624 not work yet 100%. It generates the DLL's automatically
625 when compiling with --with-win32 under cygwin.
627 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
629 * lib/contrib/regex.c is not compiled on WIN32.
631 * Added silc_net_get_socket_opt function to the
632 lib/silcutil/silcnet.h.
634 * Added includes/silcwin32.h for WIN32 specific includes
637 * Do not use ptime structure or any of the posix process
638 functions on WIN32 in lib/silccrypt/silrng.c.
640 * Added silc_gettimeofday to provide generic function
641 for struct timeval on all platforms. Added the function
642 to lib/silcutil/silcutil.h.
644 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
646 * Moved the lib/silccore/silcsockconn.[ch] to the utility
647 library as they clearly belong there. As a plus side we
648 can make the actual socket connection routines platform
651 Added also new generic function silc_socket_read and
652 silc_socket_write (that used to be silc_packet_[read/write].
653 The implementation of these are platform specific.
655 * Added WIN32 specific routines of silc_socket_[read/write]
656 to lib/silcutil/win32/silcwin32sockconn.c.
658 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Added preliminary support for native WIN32 compilation under
661 cygwin (using the -mno-cygwin option for GCC) to the
662 ./configure.in.pre. The --with-win32 now prepares the
663 compilation for native WIN32.
665 * Rewrote the SILC Scheduler interface in the file
666 lib/silcutil/silcschedule.h. The scheduler is now context
667 based and does not have anymore any global static scheduler.
668 Moved the Unix scheduler to the lib/silcutil/unix/ directory
669 and created lib/silcutil/win32 directory for WIN32 based
672 * Added Unix specific network routines to the
673 lib/silcutil/unix/silcunixnet.c and the old
674 lib/silcutil/silcnet.c includes now only generic routines.
676 Added WIN32 specific network routines to the
677 lib/silcutil/win32/silcwin32net.c.
679 * Added Unix specific utility functions from the
680 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
682 * Added WIN32 SILC Scheduler to the file
683 lib/silcutil/win32/silcwin32schedule.c. The code is of course
686 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
688 * Do not handle JOIN notify in the server if the target client
689 is not registered (idata->registered == FALSE). The affected
690 file is silcd/packet_receive.c.
692 * Update the nickrec->founder in event_cumode in the Irssi SILC
693 client. Affected file irssi/src/silc/core/silc-channels.c.
695 * Fixed the CUMODE_CHANGE notify handling in the server when
696 server and router are announcing their clients on channels.
697 Now the mode changes are saved and notified correctly. The
698 affected file is /silcd/packet_receive.c.
700 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
701 They really did not replace the cache entry in the ID Cache.
702 Now they do that. Affected file silcd/idlist.c.
704 * Fixed the KICK notify handling in the Irssi SILC client to
705 update the channel records so that the kicked client does not
706 appear to be on the channel. The affected file is
707 irssi/src/silc/core/silc-channels.c.
709 * Always update the conn->current_channel when executing command
710 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
712 * Fixed the KILL notify handling in Irssi SILC client to remove
713 the killed client on all channels.
715 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Fixed the silc_parse_command_line to remove extra spaces
718 from the start and end of the arguments. Affected file is
719 lib/silcutil/silcutil.c.
721 * Cancel and free any active protocol in the function
722 silc_server_close_connection. Affected file silcd/server.c.
724 * Cancel and free any active protocol in the function
725 silc_client_close_connction. Affected file is
726 lib/silcclient/client.c.
728 * Do not execute the KILL command for clients that are in
729 history (ie. they are not in the network). Affected file is
732 * Fixed KILL notify handling, client does not crash anymore.
733 Affected file irssi/src/silc/core/silc-channels.c.
735 * Reduced the default packet buffer size from 2048 to 1024 in
736 lib/silccore/silcpacket.c.
738 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
739 counter to the SKE context that is incresed when the SKE library
740 performs async operation outside the library. If the outside
741 process frees the SKE context and FREED status will be set
742 and the library will detect after the sync operation that the
743 libary is freed. The affected files are
744 lib/silcske/silcske[_status].[ch].
746 * Resolve the client entry information in the function
747 silc_client_channel_message to assure that NULL pointer is not
748 passed as client entry to the application. */
750 * Fixed the task timeout calculation to assure that there is
751 never negative timeouts. The affected file is
752 lib/silcutil/silcschedule.c.
754 * Fixed the channel user mode notification sending in server.
755 It was sent point-to-point to the router (or to server by router)
756 but it needs to be destined to a channel. The routines now
757 supports sending the channel user mode notifys to the channels
758 when announcing clients and channels. Affected files are
759 silcd/server.c and silcd/packet_receive.c.
761 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
762 It did not actually replace the old channel entry in the cache.
763 Affected file lib/silcclient/client_notify.c.
765 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Fixed a possible crash in silc_packet_send_prepare. It now
768 assures always that there is enough space in the buffer and
769 at the tail area of the buffer (for MAC).
771 Fixed the inbound buffer reallocation in silc_packet_read.
772 It was old code and did not handle the reallocation correctly.
775 The affected file is lib/silccore/silcpacket.c.
777 * Fixed buffer overflow in silc_parse_nickname in the file
778 lib/silcutil/silcutil.c.
780 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * make install generates new server keys only if there is not
785 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
788 Added check that if the NOREPLY is set then we will not send
789 the away message. This avoids infinite loop of away messages
790 if both clients are away. The affected file is
791 lib/silcclient/client_prvmsg.c.
793 * Fixed client crash if /NICK was given without arguments.
794 Affected file lib/silcclient/command.c.
796 * Server does not send the invite list in INVITE command back
797 to the client if the list was not altered. Added this notion
798 to the protocol spec as well. Affected file silcd/command.c.
800 Fixed possible crash in INVITE command by checking the
801 value of silc_server_get_client_route command.
803 * Fixed the INVITE notify type handling. The arguments are now
804 taken in correct order and client does not crash. The affected
805 file is irssi/src/silc/core/silc-channels.c.
807 Removed the "Inviting xxx to channel" message from the
808 client library away and let the application handle it.
809 Affected file lib/silcclient/command.c. Added that message
810 to Irssi SILC client's message formats.
812 * Fixed CMODE command crash in client. It now checks the
813 amount of arguments correctly and does not crash. The affected
814 file is lib/silcclient/command.c.
816 * Do not create new channel automatically in silc_channels_join
817 but check whether the channel by that name already exists.
818 Affected file irssi/silc/core/silc-channels.c.
820 * Do not send the SERVER_SIGNOFF to router if the disconnected
821 entity was the router. Affected file silcd/server.c.
823 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
824 SILC client as it was missing from there.
826 Added the handling of the KICK notify to the Irssi SILC client
827 as it was missing. Added "you have been kicked" message to
828 Irssi SILC client's message modules formats.
830 Added the handing of the KILL notify to the Irssi SILC client
831 as it was missing. Added the kill message module formats
834 The affected file is irssi/src/silc/core/silc-channels.c.
836 * The router did not save the channel mode the server announced.
837 Affected file silcd/packet_receive.c.
839 * Fixed a possible crash in INFO command in server. If the
840 server did not provide the server info it crashed. Affected
841 file silcd/command.c.
843 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Fixed the GETKEY command in the server to check also the
846 global list. Otherwise the GETKEY would not work correctly
847 in normal SILC server. Affected file silcd/command.c.
849 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Fixed GETKEY crash, it crashed if the command did not succseed.
853 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
856 is now real and not just an macro interface to GMP.
858 Removed the entire GMP from the source tree and imported new
859 NSS MPI library instead. Reason for removing GMP is that it is
860 extremely large and compiles extremely slow. The NSS MPI
861 is only a few files and compiles in less than 10 seconds.
862 The speed is also about the same as GMP. The MPI is imported
865 If the system has GMP installed we will still use the GMP.
866 If it is not then the NSS MPI will be compiled.
868 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Merged a long nickname (127 characters long) crash bugfix from
871 Irssi CVS tree. Affected file irssi/src/core/misc.c.
873 * Merged a freed memory reference bugfix from Irssi CVS tree.
874 Affected file irssi/src/core/commands.c.
876 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Added the server's public key sving and verification to the
879 server when performing the SKE. This was missing and the
880 remote server's (or router's) public key was accepted without
881 checking whether we have it previously or trust it at all.
882 Affected file silcd/protocol.c.
884 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Check in the silc_server_timeout_remote if protocol is active
887 and make sure that the protocol's final callback is called so
888 that all memory if freed. Affected file silcd/server.c.
890 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * silc_server_whois_send_reply crashed the server if the nickname
893 was 127 characters long. Affected file silcd/command.c.
895 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Added sanity check to the silc_server_new_client. If the hostname
898 is provided inside username then check that the provided hostname
899 really is the same as the resolved one. If the hostname was not
900 resolved then check it from the public key. Affected file is
901 silcd/packet_receive.c.
903 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
904 if the server disconnected us and the connection is not valid
905 anymore. Affected file irssi/src/silc/core/silc-channels.c.
907 * Moved the silc_client_[chmode|chumode|chumode_char] away from
908 the library to the lib/silcutil/silcutil.[ch].
910 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Close log file after open. Affected file
913 lib/silcutil/silclog.c.
915 * Check whether sock == NULL in silc_client_send_packet and return
916 if it is. Affected file lib/silcclient/silcclient.c.
918 * Check rec->entry == NULL in the Irssi SILC Client before
919 sending the channel message. Affecte file is
920 irssi/src/silc/core/silc-servers.c.
922 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Merged a splitted window bugfix from Irssi CVS tree. The
925 affected file is irssi/src/fe-text/textbuffer-view.c.
927 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
928 It did not print nickname.
930 * Improved the distributions system a bit.
932 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
935 irssi/src/fe-text/gui-window.c.
937 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
938 to in-active server. The affected file is
939 irssi/src/silc/core/client_ops.c.
941 * Resolve the client in USERS command reply if the entry does
942 not have username resolved. The affected file is
943 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
944 command to WHOIS command to really resolve stuff. The USERS
945 is not used any more in any critical section so WHOIS can
946 be used even though it might be slower than IDENTIFY.
948 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
951 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Changed the protocol API a bit more consistent in the
954 lib/silccore/silcprotocol.[ch].
956 * Changed the following headers to ROBODoc format:
958 lib/silccore/silcpayload.h
959 lib/silccore/silcprotocol.h
960 lib/silccore/silcsockconn.h
962 All core library headers are now formatted.
964 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Fixed a bug in Irssi SILC client; do not show that you are
967 server/router operator if you really are not. Affected file is
968 irssi/src/silc/core/client_ops.c.
970 * Renamed silc_command_free_payload to silc_command_payload_free.
971 Affected file lib/silccore/silccommand.h
973 * Added silcmath.h to include the prototoypes of various routines
974 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
977 * Changed the following headers to ROBODoc format:
979 lib/silccore/silcchannel.h
980 lib/silccore/silccommand.h
981 lib/silccore/silcid.h
982 lib/silccore/silcidcache.h
983 lib/silccore/silcmode.h
984 lib/silccore/silcnotify.h
985 lib/silccore/silcpacket.h
986 lib/silcmath/silcmath.h
988 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
990 * Added checking to the server code not to start the server if
991 ciphers and stuff are not configured properly. Affected files
992 silcd/serverconfig.[h] and silcd/server.c.
994 * Changed the layout of the header files of the public interfaces
995 in the SILC libraries. The new layout supports ROBODoc
996 documentation tool (and some others) so that it is easy to create
997 a library reference manual. All the other headers and source
998 code must still follow the CodingStyle document. Also source
999 code must not include these ROBODoc stuffs, only the headers.
1000 Furthermore, all public interface headers must now be named
1001 by using `silc' prefix, example: silcapi.h, silccipher.h.
1002 Some files were renamed due to this. All the other headers
1003 must not be used as public interfaces. I will update the
1004 CodingStyle document later. Changed following headers, so far:
1006 lib/silcclient/silcapi.h
1007 lib/silccore/silcauth.h
1008 lib/silccore/silcprivate.h
1009 lib/silccrypt/silcdh.h
1011 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Removed silc_client_packet_send_flush from the client library
1016 as it is not needed. Affected file lib/silcclient/client.[ch].
1018 * Added printing of message of unresolved authentication method
1019 to the Irssi SILC client. Added it to the module formats.
1020 Removed the same message from the client library.
1022 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Added new distribution feature, DISTLABEL. Every distribution
1025 can define own preprocessor label that can be used in the
1026 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1027 file distributions, acconfig.h.pre and prepare.
1029 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Added Makefile.defines_int to include the actual definitions
1032 for Makefile.defines.in. Tested the new distribution system,
1033 created distributions and tested installation.
1035 * Added AWAY message printing to the Irssi SILC client. Added
1036 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1038 * Added SCONNECT command to call the SILC's CONNECT command.
1039 Cannot use CONNECT directly since Irssi uses that internally.
1040 Affected file irssi/src/silc/core/silc-servers.c.
1042 Added ACTION local command. It is same as ME command but takes
1043 the channel as mandatory argument.
1045 Rewrote some of the Irssi's help files to suite for SILC
1048 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Added Makefile.defines[.in] that should for now on be included
1051 in all Makefile.am file in the source tree. That file includes
1052 all common compilation definitions for SILC source tree.
1054 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Minor changes to the ./prepare script to change the package
1057 name according the distribution name to the configure.in.
1059 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * Created new distribution system. Added file `distributions'
1062 that defines all the distributions that can be created out of
1063 the SILC source tree. The ./prepare script now reads that
1064 file to determine how to prepare the distributions. The
1065 first argument to the ./prepare is the name of the distribution
1066 and second is the version of the distribution. If given
1067 without arguments it creates the default (toolkit) distribution
1068 with the default version (defined in ./prepare).
1070 All Makefile.am files that are subject to the distributions
1071 are now named as Makefile.am.pre. These are ./Makefile.am
1072 and lib/Makefile.am. Others may be changed later.
1074 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Added invite list, ban list, some key management and connection
1077 error message printing to module formats in the Irssi SILC client.
1079 * Added new silc_client_set_away_message to set the away message
1080 that is back to the person who sent private message. The
1081 affected file lib/silcclient/silcapi.h and the
1082 lib/silcclient/client_prvmsg.c.
1084 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Fixed the private message sending in the Irssi SILC client,
1087 added local command KEY to the Irssi SILC client.
1089 Added key management and key agreement message formats to the
1090 irssi/src/fe-common/silc/module-formats.[ch].
1092 Added USERS (alias WHO) printing, server/router operator
1093 indication and LIST command printing to the module formats.
1095 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Fixed channel joining notify handling, cumode notify handling
1098 from Irssi SILC client.
1100 * Added SILC specific module-formats to the Irssi SILC client so
1101 that SILC specific message hilighting, colors etc is possible.
1102 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1104 Added channel mode, channel user mode, actions, notices,
1105 whois and whowas printing to the the module-formats.c.
1107 * Fixed a bug in channel deletion in the server. The channel
1108 is not left to the cache even if the channel founder auth mode
1109 is set when there are no users anymore on the channel. Affected
1110 file silcd/server.c.
1112 * The silc_net_localhost now resolves the entire hostname including
1113 the domain name. Affected file lib/silcutil/silcnet.c.
1115 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Changed the ask_passphrase client operation to be ascynchronous.
1118 It has now a completion callback and a context that the
1119 application must call after it has got the passphrase from
1120 the user. Affected files lib/silcclient/silcapi.h,
1121 lib/silcclient/protocol.c, lib/silcclient/command.c and
1124 Added SilcAskPassphrase callback that the application calls
1125 to deliver the passphrase to the library.
1127 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1128 The public key verification and especially a certificate
1129 verification is asynchronous procedure.
1131 Added new SILC_SKE_STATUS_PENDING status to indicate the
1132 request is pending and a callback will be called to finalize
1135 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1136 indicate that remote end did not send its public key (or
1137 certificate), even though we require it. Added check for this
1138 condition in the SKE. This was a security bug, now fixed.
1140 Defined new SilcSKEVerifyCbCompletion callback that is called
1141 when the verification process is completed.
1143 The affected files lib/silcske/silcske_status.h and
1144 lib/silcske/silcske.[ch].
1146 * Changed the verify_public_key client operation to be async
1147 as well. Defined SilcVerifyPublicKey callback that is used to
1148 indicate the success of the public key verification process.
1150 Changed the server and client to use the new async client
1153 * Changed the Irssi SILC client's internal scheduler to be called
1154 twice as many times as it used to be. As a result the client
1155 should be a bit faster now. Affected file is
1156 irssi/src/silc/core/silc-core.c.
1158 * Added support to Irssi SILC client of asynchronous public key
1159 verification and passphrase inquiry. Affected file is
1160 irssi/src/silc/core/silc-core.c.
1162 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Do not say "You have left channel %s" in client library.
1165 Moved it to the application. Affected files are
1166 lib/silcclient/command.c and silc/client_ops.c.
1168 * Fixed silc_client_get_clients. Command context was not
1169 duplicated and was freed memory in the callback. Affected
1170 file lib/silcclient/idlist.c.
1172 * Do not say "you are now talking..." on JOIN command in the
1173 client library. The appliation must handle it.
1175 * Do not say ".. changed topic to" in command reply in the
1176 client libary. The application must handle it.
1178 * Fixed TOPIC command sending in the client library.
1180 * Fixed a memory leak in silc_client_command_free in the file
1181 lib/silcclient/command.c.
1183 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * Imported a modified version of Irssi client to the source tree.
1186 The Irssi will be used to create a new client called
1187 Irssi SILC. Imported to irssi/.
1189 Added silc_core_init_finish function to the Irssi. Affected
1190 file irssi/configure.in.
1192 A lot changes in the Makefile.ams around the irssi tree.
1194 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Do not rehash if the new size is same as the old size of the
1197 hash table, in the silc_hash_table_rehash*. The affected file
1198 lib/silcutil/silchashtable.c.
1200 * Replaced hash_table_del_by_context calls from the server
1201 (when channel->user_list and client->channels) to the
1202 hash_table_del as it is sufficient and faster.
1204 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Added silc_hash_table_list, silc_hash_table_get and the
1207 SilcHashTableList structure to provide an alternative way to
1208 traverse the hash table. The affected files are
1209 lib/silcutil/silchashtable.[ch].
1211 * Changed the server's idlist routines to use the hash table
1212 routines to optimize the code.
1214 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1216 * Replaced the client entry's `channel' list and channel entry's
1217 `user_list' list to hash tables for optimized lookup. Changed
1218 the code to use the hash table interface around the code.
1219 Affected file lib/silcd/idlist.[ch].
1221 * Added `auto_rehash' boolean argument to the function
1222 silc_hash_table_alloc to indicate whether the hash table should
1223 auto-rehash when it thinks is appropriate time. It will
1224 increase the hash table size if the there is twice as much
1225 entries in the table than the size of the table, and will
1226 decrease the size if there are twice as less entries than
1227 the size of the table.
1229 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1233 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * silc_idcache_purge_by_context deletes the entry now by context
1236 as it is supposed to do. Affected file lib/silccore/idcache.c.
1238 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1239 client is not anymore valid (WHOWAS givens the info) and not
1240 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1242 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Removed the `data' and `data_len' arguments from the ID Cache
1245 interfaces and added `name' argument. ID Cache does not handle
1246 anymore the binary data only a names associated with given ID.
1248 * When hashing a Client ID with silc_hash_id the entire ID is
1249 not hashed anymore, instead only the hash of the Client ID is
1250 hashed. This way we can access the Client ID from the cache
1251 with Client ID but with the hash of the ID (which is a hash of
1252 the nickname) as well without any difference in performance.
1254 Added also silc_idcache_find_by_id_one_ext to do one on one
1255 searching when we have the actual ID. Added also function
1256 silc_hash_client_id_compare. The affected files are
1257 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1259 * When hashing the name associated with a ID it is always done
1260 in lowercase. This way we can access the cache without worrying
1261 about case-sensitivity, even though, for example nicknames are
1264 * Fixed a bug in server with channel message sending. It put
1265 wrong ID type as destination ID. The affected file
1266 silcd/packet_send.c.
1268 * silc_idcache_del_by_context now deletes from all hash tables
1269 by context. Affected file lib/silccore/idcache.c.
1271 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Changed the client library to use the new ID Cache interface.
1274 Changes around the source tree.
1276 * Added silc_hash_table_rehash_ext to rehash with specific
1277 hash function. Affected file lib/silcutil/silchashtable.[ch].
1279 * Added silc_hash_string_compare to compare two strings in the
1280 hash table. Affected file lib/silcutil/silcutil.[ch].
1282 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Added new function silc_idcache_del_by_context into the
1285 lib/silccore/idcache.[ch].
1287 * Changed the server's ID list routines to use the new ID Cache
1288 interface. Changes around the source tree.
1290 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Added silc_hash_table_del[_by_context]_ext functions in to the
1293 lib/silcutil/silchashtable.[ch].
1295 Removed silc_hash_table_find_all* routines and added new
1296 silc_hash_table_find_foreach to replace them.
1298 Added silc_hash_table_replace_ext function as extended
1299 replacing function. Separated the simple hash table interface
1300 from the extended hash table interface in the file
1301 lib/silcutil/silchashtable.h.
1303 * Fixed minor bugs and changed it to use some of the new
1304 hash table functions in lib/silccore/idcache.c
1306 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Added new function silc_hash_table_find_all to return all keys
1309 in the hash table by the specified key. As the hash table is
1310 collision resistant it also makes it possible to have several
1311 duplicate keys in the hash table. This function may be used to
1312 find all of the keys from the hash.
1314 Added user_context arguments to the SilcHashFunction,
1315 SilcHashCompare and SilcHashDestructor to deliver user specified
1318 Added new fuctions silc_hash_table_find[_all]_ext to do
1319 extended lookup with specified hash and compare functions and
1320 specified user contexts.
1322 Added new function silc_hash_table_add_ext to add the key
1323 with specified hash function and user context.
1325 Added new function silc_hash_table_foreach to traverse all
1326 entrys in the hash table. Added SilcHashForeach callback
1329 Added new function silc_hash_table_del_by_context to delete
1330 the entry only if the context associated with the key matches.
1332 Affected files are lib/silcutil/silchashtable.[ch].
1334 * Removed silc_hash_[server/client/channel]_id and added just
1335 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1336 silc_hash_id_compare to compare two ID's using as the hash table
1337 comparison function. Added also silc_hash_data to hash
1338 binary data and silc_hash_data_compare to compare it.
1340 * Removed silc_idlist_find_client_by_hash as it is not needed
1341 anymore. Affected file silcd/idlist.[ch].
1343 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1344 to use internally the SilcHashTable. The new ID Cache is a lot
1345 faster than the old one. Some of the ID Cache interface was also
1346 rewritten and obsolete and stupid functions were removed.
1348 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1350 * Added entry_count field to the SilcHashTable to keep the number
1351 of the entries in the table. Implemented the function
1352 silc_hash_table_rehash. Added new function
1353 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1355 Fixed a minor bug in silc_hash_table_free.
1357 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1358 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1359 into the lib/silcutil/silcutil.[ch].
1361 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Implemented a collision resistant hash table into the
1364 lib/silcutil/silchashtable[ch]. See the header and the source
1365 for the SilcHashTable API.
1367 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1369 * Merged dotconf version 1.0.2 into lib/dotconf.
1371 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Do not compile anything in lib/silcsim/* if the SIM support
1374 is not enabled. The tree should now compile without problems
1377 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1379 * Compiled the SILC under cygwin. Compiled and tested briefly
1380 without problems. More tests needed. The SIMs didn't compile
1383 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1385 * Fixed possible crash in silc_get_username in the
1386 lib/silcutil/silcutil.c.
1388 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Fixed a va_arg in silc/client_ops.c.
1392 * Oops, RC5 routines were named AES and caused some problems
1393 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1395 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Added new SilcIDIP structure into the lib/silccore/id.h and
1398 replaced the old `ip' fields from all SILC ID's to that type.
1399 This is a step towards IPv6 support.
1401 The silc_id_get_len takes now the ID as an extra argument.
1402 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1403 both IPv4 and IPv6 based ID's.
1405 The affected files are lib/silccore/id.[ch] and other files
1406 around the tree using these routines.
1408 * Removed the ID length arguments in server from various
1409 silc_server_send_notify_* routines -> they are not needed
1412 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1414 * Fixed memory leak in silc_encode_pem_file in the file
1415 lib/silcutil/silcutil.c.
1417 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Check minor version as well in the SKE. Affected files are
1420 silcd/protocol.c and lib/silcclient/protocol.c.
1422 * Added --identifier option to the server so that an identifier
1423 can be when creating the public key for the server. Affected
1424 file is silcd/silcd.c.
1426 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1427 lib/silccrypt/silcpkcs.c.
1429 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Register default ciphers and stuff when using -C option with
1432 the server. Affected file sildc/silcd.c.
1434 * Put back the servers public key filename format, it is better
1435 than the new one. For now, the client keys are saved with the
1436 new filename format. The affected file silc/client_ops.c.
1438 * Implemented the Cipher API for the rest of the ciphers that
1439 did not implement it or implemented it the wrong way.
1441 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Register default ciphers and stuff when using the -S option
1444 in the client. Affected file silc/silc.c. Same also when
1445 creating new key pair with -C option.
1447 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Fixed the silc_verify_public_key client operation function to
1450 save the public keys differently. The fingerprint is now
1451 used as filename and not the hostname. This way also the
1452 client keys are saved uniquely and not with hostnames. The
1453 affected file is silc/client_ops.c.
1455 * Trimmed the silc_hash_fingerprint function to remove extra
1456 whitespaces from the end of the fingerprint. The affected
1457 file is lib/silccrypt/silchash.c.
1461 * Added silc_cipher_register_default function to register all
1462 default ciphers. It can be used when configuration files
1463 does not exist and the application does not want any specific
1464 ciphers in any specific order.
1466 The SilcDList is now used as silc_cipher_list dynamically
1467 allocated cipher list. Removed the static list all together
1468 and now all ciphers must be allocated to the dynamic list.
1469 The silc_cipher_alloc routine was changed to check only the
1472 All silc_cipher_* routines that used to return int returns
1475 The affected files lib/silccrypt/silccrypt.[ch].
1477 * The same thing was done to silc_hash_* as for silc_cipher_*
1478 routines. Affected files lib/silccrypt/silchash.[ch].
1480 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1481 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1482 Added also silc_pkcs_[un]register[_default] functions.
1483 Removed the data_context from the PKCS API.
1485 * Added silc_hmac_register_default function to register default
1486 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1487 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1488 to unregister all hmacs at once.
1490 * Register the default ciphers, hash functions, PKCSs and HMACs
1491 if client's configuration file does not exist. The affected
1494 * The client did not load the hash functions from the SIM
1495 modules at all. Added support for this. Affected file is
1496 silc/clientconfig.c.
1498 * When decoding public key with silc_pkcs_public_key_decode, check
1499 the supported algorithm only if PKCS are registered. Affected
1500 file lib/silccrypt/silcpkcs.c. The same was done with the
1501 silc_pkcs_private_key_decode.
1503 * Fixed the SILC List routines to keep the list always in order.
1504 It used to change the list's order when traversing the list but
1505 not it preserves the order. Affected file lib/trq/silclist.h.
1507 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Added the client library to use the SilcSocketConnection's
1510 reference counter (by silc_socket_dup) to prevent the bug that
1511 the socket object may be freed underneath async operation.
1513 * The name resolv library checking fixes in the configure.in.pre.
1516 * Created new version of the protocol drafts for future
1517 development. The -03 drafts are the ones that will be changed
1518 in the trunk now and the -02 will remain as they are.
1520 * Send list of CUMODE notifys to the router when announcing
1521 the channel users to the router. Affected file silcd/server.c.
1522 If the router receiving channel founder CUMODE for a channel
1523 that already has channel founder it will send CUMODE notify
1524 to the sender to remove the channel founder rights from the
1525 announced client. Affected file silcd/packet_receive.c.
1527 * The CUMODE notify may now use Server ID as well as the entity
1528 who changes the mode. Updated protocool specs.
1530 * Updated INSTALL and README files.
1532 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1534 * New web pages in the http://silc.pspt.fi. The pages was
1539 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * Implemented the [DenyConnectin] config section in the server.
1542 Added silc_server_config_denied_conn to check whether incoming
1543 connection is denied. Affected file silcd/serverconfig.[ch].
1545 * Do not check the ports when checking the incoming configuration
1546 data if the port is 0, meaning any. Affected file is
1547 silcd/serverconfig.c.
1549 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Fixed buffer overflow in silc_string_compare in the file
1552 lib/silcutil/silcutil.c.
1554 * Fixed double free in silc_server_command_leave in the file
1557 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Fixed the version checking in the server. Affected file is
1562 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Fixed the configuration data fetching when accepting new
1565 connections in the server. Affected file silcd/server.c.
1567 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Added `sender_entry' argument to the function
1570 silc_server_packet_relay_to_channel so that we can check
1571 whether some destination actually belongs to the same route
1572 the sender belongs (ie, we must not resend the packet to the
1573 sender). Affected file silcd/packet_send.[ch].
1575 * Added `servername' field to the SilcClientEntry in the server
1576 to hold the name of the server where client is from. Affected
1577 file is silcd/idlist.h.
1579 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Moved the channel message encrypting in the router betwen
1582 router connections from silc_server_channel_message to the
1583 silc_server_packet_relay_to_channel since we want to check
1584 whether we have anybody channel before encrypting anything.
1585 Affected files silcd/packet_[receive/send].c.
1587 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1589 * Fixed the [AdminConnection] server config section to support
1590 multiple entries. Affected file silcd/serverconfig.c.
1592 * Added support into the server to check the validity of the
1593 incoming connection before executing any KE or authentication
1596 * The connection configuration is now saved to the KE and
1597 connection auth protocol contexts and not fetched anymore in
1598 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1600 * The local hosts listenning address and port is also resolved
1601 now when starting the server. We want to have the socket object
1602 to include the real address and port for the listener. Added
1603 new function silc_net_check_local_by_sock into the files
1604 lib/silcutil/silcnet.[ch].
1606 * Fixed a broadcast bug in server -> do not broadcast if we
1609 * Fixed a routing bug. Do not route broadcast packets ever.
1610 Broadcast packets must be processed always and not routed since
1611 they may be destined to some other host than yourself and thus
1612 would get routed without no good reason. Affected file is
1615 * Added function silc_server_config_is_primary_route to check
1616 whether primary router connection has been configured (a router
1617 configuration that we are initiating). If there is not, we
1618 will assume that there is only two routers in the SILC network
1619 and we will use the incoming router connection as our primary
1620 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1622 * Changed the order of the broadcasting. Broadcast _after_ the
1623 packet has been processed not before. Affected file is
1626 * Fixed a [ClientConnection] parsing bug. The port was never
1627 parsed correctly thus resulting to port 0. Affected file
1628 silcd/serverconfig.c.
1630 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1631 argument and did not set the broadcast packet flag. Affected
1632 file silcd/packet_send.c. Fixed same bug in the function
1633 silc_server_send_notify as well.
1635 * If we receive NEW_ID packet for our own ID in the server, ignore
1638 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1642 * Removed the nickname from the Private Message Payload.
1643 Updated the code and the protocol specs.
1645 * Updated protocol specs for submitting to the IETF.
1647 * Tweaked the Random Number Generator a bit. Affected file
1648 lib/silccrypt/silcrng.c. Exported a new function
1649 silc_rng_[global]_add_noise which can be used to add more
1652 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1654 * Do not parse packets with different timeout when protocol
1655 is active -> may cause problem with rekey. Affected file
1658 * When server receives signoff notify it must not create
1659 new channel key if the client is on any channels since the
1660 sender of the signoff notify will create it.
1662 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Added printing of error messages during SKE protocol from the
1665 failure packet sent by server during SKE. Affected file
1668 * Removed the client's failure_callback handling with timeout
1669 and handle it immediately when received.
1671 * The SKE library returned wrong type in SUCCESS and FAILURE
1672 packets. They must be 32 bit MSB not 16 bit MSB.
1674 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Ok, rewrote the logic of the re-key and now it seems to work.
1677 I tested it on high traffic with frequent re-keys without
1678 problems. Added hmac_receive (and renamed hmac to hmac_send)
1679 in SilcClientConnection in lib/silcclient/client.h and
1680 in SilcIDListData in silcd/idlist.h. Also, removed the
1681 SilcPacketParserContext's cipher and hmac fields as they are
1682 not needed anymore and actually caused some problems when
1683 the ciphers and hmac's changed underneath the packet parser.
1685 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * If re-key protocol is active then process the incoming packets
1688 synchronously since we must assure that icoming packets encrypted
1689 with the old key is processed before the new keys is set to
1690 use. This is true other packets than for REKEY packets.
1691 Affected file silcd/server.c. The same was done to client library
1692 as well, affected file lib/silcclient/client.c.
1694 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Fixed bug in client and server to accept the force send if
1697 the packet is send from silc_[server/client]_packet_process
1698 function. Otherwise the packets are never delivered, oops.
1700 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Disable force sending of packets when REKEY protocol is active.
1703 We must assure that no packet is sent directly when rekey is
1704 performed. All packets must be sent through packet queue.
1705 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1706 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1707 function is silc_[server/client]_packet_send_real to check
1710 * Replaced the SIM paths from example config files to
1711 /usr/local/modules. Also, make install creates now
1712 /usr/local/silc/logs directory to hold all the SILC server
1715 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1717 * Made the configure.in.pre work on Solaris. Patch by salo.
1719 * Made all ciphers compatible with non-x86 machines. Defined
1720 CBC mode macros into lib/silccrypt/ciphers_def.h.
1722 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1724 * Fixed the make install.
1726 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * When MAC computation fails the silc_packet_decrypt returned 0
1729 even though it was supposed to return -1. Fixed this. The
1730 affected file is lib/silccore/silcpacket.c.
1732 * Do not replace the config files in /etc/silc (in make install)
1733 if they already exist. Affected file ./Makefile.am.
1735 * Do not send re-key packets immediately but through packet queue.
1736 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1738 * Changed silc_net_check_host_by_sock to return FALSE if the
1739 IP/DNS could not be resolved. Though, it returns the IP address
1740 now even if it could not resolve it (but returns also FALSE).
1741 Affected file lib/silcutil/silcnet.[ch].
1743 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Added silc_pkcs_decode_identifier to decode the public key's
1746 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1747 Added also silc_pkcs_free_identifier. Added also new context
1748 SilcPublicKeyIdentifier.
1750 * Added -S option to the silc client. It is used to dump the
1751 contents of the specified public key file.
1753 * Changed the PKCS api to return the public key length when
1754 setting the public key.
1756 * Fixed a fatal bug in the public and private key file loading.
1757 Affected file lib/silccrypt/silcpkcs.c.
1759 * Execute the packet parsing for client with zero (0) timeout
1760 if the protocol is active. Affected file silcd/server.c.
1762 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Made the key generation options to the silcd program. Added
1765 -C option, equivalent to client's option.
1767 * Added new [ServerKeys] config section to the server. It
1768 configures the server's public and private key.
1770 * Defined generic Public Key Payload into the protocol
1771 specification to send specific type of public keys and
1774 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1775 public key or certificate.
1777 * Implemented the GETKEY command to the server and to the
1778 client library and on user interface.
1780 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Made preliminary `make install' work.
1784 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Added SilcServerRekey context into silcd/idlist.h.
1788 * Added the PFS support as defined in the specification to the
1789 SKE protocol. Affected files lib/silcske/*.c.
1791 * Added `ske_group' field to the SilcServerRekey context to hold
1792 the number of the SKE group that is used with PFS in re-key.
1793 Affected file silcd/idlist.h.
1795 * Added PFS re-key support to the server. Affected file is
1798 * Added silc_protocol_cancel to cancel execution of the next
1799 state of the protocol. Affected file is
1800 lib/silccore/silcprotocol.[ch].
1802 * Added the re-key support with and without PFS to the client
1803 library. Re-key is performed once in an hour, by default.
1805 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1806 Added silc_client_rekey_callback and silc_client_rekey_final.
1807 Affected files are lib/silcclient/protocol.[ch] and
1808 lib/silcclient/client.[ch].
1810 * Removed the `hmac_key' and `hmac_key_len' fields from the
1811 SilcClientConnection structure; not needed. Affected file is
1812 lib/silcclient/client.h.
1816 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Do not ask whether user wants to use the negotiated private key
1819 for private messages, just use it. Affected file is
1820 silc/local_command.c.
1822 * Added `send_enc_key' and `enc_key_len' fields to the
1823 SilcIDListData structure since they are needed in the re-key
1824 phase. Affected file is silcd/idlist.[ch].
1826 * Implemented the simple re-key protocol into the server.
1827 Affected files silcd/server.c and silcd/protocol.[ch]. The
1828 re-key will be performed once in an hour, by default.
1830 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1831 Added silc_server_rekey, silc_server_rekey_callback and
1832 silc_server_rekey_final.
1834 * Removed Tunneled flag from the protocol. Updated the code
1835 and the specifications.
1837 * Adde `pfs' field to the SilcIDListData to indicate whether
1838 the PFS is to be performed in the re-key. Affected file is
1841 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1844 int64 of at least the xintXX size. If void * is less that 4
1845 bytes uint32 * will be used. Defined bool as boolean.
1847 * Changed _ALL_ unsigned long and unsigned int to uint32,
1848 unsgined short to uint16 in the source tree.
1850 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1851 not handle clients that has entry->data.registered == FALSE.
1852 They are not in the network anymore. Affected file is
1855 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Implemented the sending of the SERVER_SIGNOFF notify in the
1858 server. Affected file is silcd/server.c.
1860 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1861 Added also silc_notify_payload_encode_args into the
1862 lib/silccore/silcnotify.[ch].
1864 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1865 Affected file silcd/packet_receive.c.
1867 * Implemented the SERVER_SIGNOFF notify handling in the client
1868 library. Affected file lib/silcclient/client_notify.c. Also,
1869 implemnted the printing of the SERVER_SIGNOFF info to the
1870 application. Affected file silc/client_ops.c.
1872 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1873 if the deleting was successful. Affected file silcd/idlist.[ch].
1875 * Added support for public key authentication in the connection
1876 authentication protocol in the client library. Affected file
1877 lib/silcclient/protocol.c.
1879 * Changed the server's silc_idlist_get_clients_by_* interface
1880 to support already allocated array so that new entries may be
1881 added to pre-allocated array. Affected file silcd/idlist.[ch].
1882 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1883 and command replies.
1885 * All command reply functions in the server now calls the
1886 pending command callback even if error occured. This way the
1887 error will be delivered to the client as well. Affected files
1888 silcd/command.c and silcd/command_reply.c.
1890 * Fixed INFO command to return local server's info if no server
1891 was provided. Affected file lib/silcclient/command.c.
1893 * Removed RESTART command for good. Updated the code and the
1896 * Rewrote parts of the task system. It is a bit simpler now.
1897 Removed unsued task priorities. The affected files are
1898 lib/silcutil/silctask.[ch].
1900 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Moved the USERS printing from the library to the application.
1903 Affected files lib/silcclient/command.c and silc/client_ops.c.
1905 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * Added channel key re-key support. The re-key is perfomed
1910 only by the router and is done once in an hour. Added `rekey'
1911 field to the SilcChannelEntry in the server. Affected files
1912 silcd/server.c and silcd/idlist.h.
1914 * Added silc_task_unregister_by_context into the file
1915 lib/silcutil/silctask.[ch].
1917 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Added SILC_UMODE_GONE mode to indicate when the client is not
1920 present in the SILC network. Added also support to the local
1921 command AWAY that will set this mode. Added support of showing
1922 "xxx is gone" in WHOIS command. The USERS command shows the
1923 gone status as well.
1925 * Fixed setting server and router operator privileges in the
1926 server's UMODE command. Affected file silcd/command.c.
1928 * Merged the SKE KE1 and KE2 payloads into one payload. The
1929 new KE payload is equivalent to the old KE2 payload.
1931 Cleaned up the SKE Start Payload parsing. It now uses the
1932 simple buffer unformatting to do the parsing. A lot faster
1935 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1936 to the SKE that is used to indicate whether both of the SKE
1937 parties should perform authentication. By default only the
1938 responder performs authentication. By setting this flag also
1939 the initiator must do authentication. By default it is unset
1940 since in normal SKE case, client to server connection, only
1941 the responder should do authentication. When doing SKE between
1942 two clients both should perform authentication. Updated the
1943 code and the protocol specs.
1945 * A little fix to IDENTIFY command in the server. Search the
1946 client first by hash not nickname. Affected file is
1949 * Fixed the silc_client_close_connection to support closing
1950 the client to client connections wihtout deleting too much
1951 data. Affected file lib/silcclient/client.c.
1953 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1954 are received if protocol used to be active but is not anymore
1955 the application would crash due to NULL pointer dereference.
1956 Affected files silcd/server.c and lib/silcclient/client.c.
1958 * Added `hash' field to the SilcClientConnection to include
1959 the hash function negotiated in the SKE protocol.
1961 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1962 to set the channel founder authentication data. A client can
1963 claim the founder rights later by providing the authentication
1964 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1965 This way the channel founder can regain the channel founder
1966 privileges even it is left the channel. This works only on
1967 local server and the client must be connected to the same
1968 server to be able to regain the founder rights. Updated the
1969 protocol specs accordingly.
1971 Added support to the CMODE command in the client to set the
1972 founder auth data. Read the README to see how to set it.
1974 Added support to the CUMODE command to claim the founder
1975 rights. Read the README to see how to do it.
1977 Added support for the founder authentication to the Channel
1978 Entry in the server. Affected file silcd/idlist.h.
1980 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1981 server's CMODE command. Affected file silcd/command.c.
1983 * Added the following new functions into lib/silccore/silcauth.[ch]:
1984 silc_auth_get_method and silc_auth_get_data.
1986 * The server now saves the remote hosts public key to the
1987 SilcIDListData pointer. Affected file silcd/protocol.c.
1989 * The normal server now does not remove the channel entry from
1990 the cache if the founder authentication data is set. It used
1991 to remove it if the founder was the last one on the channel on
1992 the server and left the channel. The auth data is saved and
1993 if the channel is re-joined later the old entry is used with
1994 the old auth data. Affected files silcd/command_reply.c and
1997 * Removed the `pkcs' field from the SilcIDListData structure
1998 in the server; it is not used. Affected file silcd/idlist.h.
2000 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2002 * Fixed packet processing on slow links. Partial packets were
2003 never re-processed because the incoming data buffer was cleared
2004 by the application. Application must not directly clear the
2005 sock->inbuf, the packet processing routines handle it. Fixed
2006 this in client library and in server.
2008 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Fixed the WHOIS and IDENTIFY send reply function to really
2011 check whether to send list or just one entry. Affected file
2014 * Cleaned up the LEAVE command's channel key distribution. The
2015 affected file silcd/command.c.
2017 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2018 can enforce the channel mode as well. In that case the ID
2019 includes the ID of the server. The code now enforces the
2020 mode change if the router have different mode than the server.
2022 * The notify client operation with CMODE_CHANGE notify can now
2023 return NULL client_entry pointer if the CMODE was not changed
2024 by client. Application must check for this.
2026 * Added <Server ID> argument to INFO command to support server
2027 info fetching by Server ID.
2029 * Added silc_server_announce_get_channel_users to get assembled
2030 packets of channel users of the specified channel. Affected
2031 file silcd/server.[ch].
2033 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2034 was freed underneath the ID Cache.
2036 * Re-announce clients when the server received CHANNEL_CHANGE
2037 notify from the router. Affected file silcd/packet_send.c.
2039 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2042 crashed since it did not handle the fact that there is no cipher
2043 called "3" and didn't check the error condition. Now fixed.
2045 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2046 flag. It can be used to send message requests.
2048 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Implemented the RESTART command in the client.
2052 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2053 notice type messages. Added notice printing to the user
2056 * The channel keys are not re-generated if the channel's mode
2057 is PRIVKEY, ie private key on the channel exists. Affected
2058 files silcd/server.c and silcd/command.c.
2060 * Fixed a little bug in channel message delivery when channel
2061 private keys are set in the server. Affected file is
2062 silcd/packet_send.c.
2064 * Changed the setting on channel->on_channel = TRUE from the
2065 silc_client_save_channel_key to the JOIN command reply. The
2066 key payload is not received if the private channel key is set.
2067 Affected file lib/silcclient/command_reply.c and the
2068 lib/silcclient/client_channel.c.
2070 * When the CMODE_CHANGE notify is sent and the channel private
2071 key mode is removed the channel key must be re-generated in
2072 other cells as well. Added this support for the router in the
2073 silcd/packet_receive.c.
2075 * Added new local command NOTICE to send notice message on
2076 channel. Affected file silc/local_command.[ch].
2078 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Added new local command ME to the client. It is used to send
2081 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2082 some action. Affected file silc/local_command.[ch].
2084 * Changed channel_message and private_message client operations
2085 to deliver the message flags to the application. Added also
2086 the `flags' arguments to the silc_client_send_channel_message
2087 and silc_client_send_private_message functions. Affected file
2090 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Redefined the Private Message Payload to support private message
2093 keys and to support the new private message flags. Updated
2094 the protocol specs. Flags makes it possible to have for example
2095 CTCP style messages.
2097 * Added new type SilcPrivateMessagePayload and defined an API
2098 for it in the lib/silcclient/silcprivate.[ch].
2100 * Tested private message private keys successfully. Tested the
2101 private message key set, unset and list commands with the new
2104 * Redefined the Channel Message Payload to include the channel
2105 message flags (equal with private message flags) to support
2106 for example CTCP style messages.
2108 * Defined some of the message (for channel and private message)
2109 flags. Updated the protocol specs and added the flags to the
2110 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2112 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2114 * Added SilcKeyAgreementStatus type to the key agreement routines
2115 to indicate the current status and error if one occured.
2116 The status types are defined in the lib/silcclient/silcapi.h.
2118 * Added new local command KEY that is used to set and unset private
2119 keys for channels, set and unset private keys for private messages
2120 with remote clients and to send key agreement requests and
2121 negotiate the key agreement protocol with remote client. The
2122 key agreement is supported only to negotiate private message keys,
2123 it currently cannot be used to negotiate private keys for channels,
2124 as it is not convenient for that purpose.
2126 * Fixed a minor pending callback setting bug in the function
2127 silc_client_get_client_by_id_resolve, now the function works.
2128 Affected file lib/silcclient/idlist.c.
2130 * Added function silc_net_get_local_port to get local bound
2131 port by socket. Added to lib/silcutil/silcnet.[ch].
2133 * Added `sockets' and `sockets_count' fields to the SilcClient
2134 object. They hold the sockets of the listenning sockets in
2135 the client. Listenning sockets may be for example the key
2136 agreement server. Affected file lib/silcclient/client.[ch].
2137 Added functions the silc_client_add_socket and the
2138 silc_client_del_socket. They are exported to the application
2141 * Added ~./silc/clientkeys to support other client's public keys.
2143 * Renamed verify_server_key client operation to verify_public_key
2144 and added one argument to indicate the type of the connection
2145 (server, client etc.).
2147 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Added silc_server_connection_auth_request to handle the
2150 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2151 silcd/packet_receive.[ch].
2153 * Added silc_server_send_connection_auth_request into the
2154 silcd/packet_send.c to send the connection auth request packet.
2156 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2159 * Fixed the public key authentication in responder side in the
2160 server. The `auth_data' pointer includes the SilcPublicKey
2161 not the path to the public key. Affected file silcd/protocol.c.
2163 * Implemented the public key authentication in the initiator side
2164 in the server. Affected file silcd/protocol.c.
2166 * Removed the [RedirectClient] config section from the server
2167 configuration. Is not needed and I don't want to implement it.
2169 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Cleaned up the CMODE command in the server. It now works
2172 correctly and supports all the modes defined in the protocol.
2173 Affected file is silcd/command.c.
2175 * Added `hmac_name' field to the SilcChannelEntry in the server
2176 to hold the default HMAC of the channel. It can be set when
2177 creating the channel (with JOIN command). Affected files
2180 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2181 type to indicate the change of the current cipher and hmac
2182 on the channel. Client can safely ignore the <cipher> argument
2183 (if it chooses to do so) since the CHANNEL_KEY packet will
2184 force the channel key change anyway. The <hmac> argument is
2185 important since the client is responsible of setting the new
2186 HMAC and the hmac key into use.
2188 * Fixed the CMODE command in the client library as well.
2190 * Tested CMODE command in router environment successfully.
2192 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Show the version of the remote client (or server) when connecting
2195 to the server. It is logged to the log file. Affected file
2196 is silcd/protocol.c.
2198 * Fixed the KILLED notify handling in the client library. The
2199 client must be removed from all channels when receiving the
2202 Also, do not remove the client entry when giving the KILL
2203 command but when the KILLED notify is received.
2205 * Removed silc_idlist_find_client_by_nickname from the server.
2206 Not needed anymore. Affected files silcd/idlist.[ch].
2208 * Implemented the CHANNEL_CHANGE notify type handling to the
2209 server. Affected file silcd/server.c.
2213 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Added silc_server_send_notify_invite to send the INVITE
2216 notify between routers.
2218 * Implemented the INVITE command correctly to the server.
2220 * Implemented the INVITE notify type handling in the server.
2222 * Implemented the INVITE command to the client library and on the
2225 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Added function silc_server_get_client_resolve to find the
2228 client entry by ID from all ID lists and then resolve it
2229 (using WHOIS) if it cannot be found. Affected file is
2232 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Implemented the BAN command to the client library.
2236 * The JOIN command in the server now checks the invite list
2239 * Changed the silc_command_reply_payload_encode_va and the
2240 silc_command_payload_encode_va to support that if argument is
2241 NULL it ignores and checks the next argument. Affected file
2242 lib/silccore/silccommand.c.
2244 * Added silc_server_send_notify_ban to send the BAN notify
2245 type between routers.
2247 * Chaned the silc_notify_payload_encode to support that if
2248 argument is NULL it ignores and checks the next argument.
2249 Affected file lib/silccore/silcnotify.c.
2251 * Tested ban lists in router environment successfully.
2253 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Implemented BAN command to the server, in silcd/command.[ch].
2257 * Removed the BAN and INVITE_LIST modes from the CMODE command
2260 * Added function silc_string_match to regex match two strings.
2261 Affected files lib/silcutil/silcutil.[ch].
2263 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * Redefined parts of the SilcChannelEntry in the server to support
2266 the new ban and invite lists.
2268 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Redefined the INVITE command. The same command can be used to
2271 invite individuals to the channel but also to manage the invite
2272 list of the channel (to add to and remove from the invite list).
2273 Updated the protocol specs.
2275 * Added new command SILC_COMMAND_BAN that can be used to manage
2276 the ban list of the channel. Updated the protocol specs.
2278 * Removed the channel modes: the SILC_CMODE_BAN and the
2279 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2280 in the CMODE command. The equivalent features are now available
2281 using INVITE and BAN commands. Updated the protocol specs.
2283 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2284 in the network about change in the current ban list. The notify
2285 type is not used by the client.
2287 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2288 support the invite lists.
2290 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Added new function silc_string_regexify that converts string
2293 including wildcard characters into regex string that can
2294 be used by the GNU regex library. Added into the file
2295 lib/silcutil/silcutil.[ch].
2297 Added silc_string_regex_combine to combine to regex strings
2298 into one so that they can be used as one regex string by
2299 the GNU regex library. Added into the file
2300 lib/silcutil/silcutil.[ch].
2302 Added silc_string_regex_match to match two strings. It returns
2303 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2305 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Imported GNU regex to the soruce tree into lib/contrib.
2308 Fixed some compiler warning from the regex.c.
2310 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Fixed MOTD command in the server to work in router environment.
2314 * Fixed the MOTD command in the client library to support
2315 the server argument in the command.
2317 * Added `nickname_len' argument to the silc_idlist_add_client
2318 in the server, as the `nickname' argument may be binary data
2321 * Added silc_idlist_get_channels to return all channels from
2324 * Implemented LIST command to the server. Affected file is
2327 * Implemented the LIST command to the client library and on the
2330 * Added [<user count>] argument to the LIST command reply.
2331 With private channels the user count is not shown.
2333 * Updated TODO and README.
2335 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * The client entry's data.registered must be TRUE even with
2338 global client entry on global client list. The data.registered
2339 is used to check whether the client is anymore in the network,
2340 for example with WHOWAS command so it must be valid.
2342 * Fixed the WHOWAS command in the server. It now actually works
2343 in router environment. Added function into silcd/command_reply.c
2344 silc_server_command_reply_whowas_save.
2346 * Added silc_idlist_purge function to the silcd/idlist.c
2347 to periodically purge the ID Cache.
2349 * Fixed INFO command in the server. It works now in router
2350 environment. Added <server name> argument to the INFO command
2351 reply. Updated the protocol specs.
2353 * Fixed minor bug in silc_idcache_purge to not purge if the
2354 expire value is zero.
2356 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2357 they were buggy because of the WHOWAS information.
2359 * Fixed local command MSG to handle the async resolving of
2360 the remote client properly. It used to fail the first MSG.
2361 Affected file silc/local_command.c.
2363 * Added `data_len' field to SilcIDCache context.
2365 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Update TODO. Todo in commands in the server.
2369 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2372 used by routers as broadcast packet to inform other routers
2373 about the changed user mode.
2375 Implemented the notify handling in the server. Affected file is
2376 silcd/packet_receive.c. Added the function
2377 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2379 * Added new generic Channel Payload and deprecated the New Channel
2380 Payload. The New Channel Payload is now the generic Channel
2383 * Added new argument `mode' to the silc_server_send_new_channel
2384 as it is required in the Channel Payload now.
2386 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2387 and created a new and real SilChannelPayload to represent the
2388 new generic Channel Payload. Implemented the encode/decode
2389 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2391 * Added silc_server_get_client_channel_list to return the list
2392 of channels the client has joined for WHOIS command reply.
2393 Affected file silcd/server.[ch].
2395 * Implemented the channel list sending in the WHOIS command reply
2396 in server and in the client.
2398 Implemented the channel list displaying on the user interface
2399 as well. Affected file silc/client_ops.c.
2401 * Added silc_channel_payload_parse_list to parse list of Channel
2402 Payloads. It returns SilcDList list of SilcChannelPayloads.
2403 Client for example can use this function to parse the list of
2404 channels it receives in the WHOIS command reply. The caller
2405 must free the list by calling silc_channel_payload_list_free.
2406 Affected files lib/silccore/silcchannel.[ch].
2408 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Added one new argument <user mode> to the WHOIS command reply
2411 to return the mode of the user in SILC. Updated the protocol
2414 Implemented it to the server and client.
2416 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Fixed the mode printing on the user interface on joining.
2419 Affected file silc/client_ops.c.
2421 * Implemented the UMODE command and user modes in general to the
2422 client library and to the user interface.
2424 * Implemented the UMODE command to the server.
2426 * The server now sends UNKNOWN_COMMAND error status if client sends
2427 unknown command. Affected file silcd/command.c.
2429 * All server commands now handle the command identifier the right
2430 way when sending the command reply to the client. The client can
2431 use to identify the command replies with the identifier.
2433 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Added silc_server_get_client_route to resolve the route to
2436 the client indicated by the client ID. Affected file is
2439 * Added silc_server_relay_packet as general function to relay
2440 packet to arbitrary destination. This deprecates functions
2441 like _send_private_message_key, _relay_notify etc. Affected
2442 file is silcd/packet_send.[ch].
2444 Removed silc_server_send_key_agreement,
2445 silc_server_send_private_message_key and
2446 silc_server_packet_relay_notify functions from the file
2447 silcd/packet_send.[ch].
2451 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2452 server. Affected file silcd/packet_receive.[ch].
2454 * Implemented the KILL command to the client. Implemented the
2455 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2456 Affected files lib/silcclient/command[_reply].c and
2457 lib/silcclient/client_notify.c. Implemented the KILL notify
2458 printing in the user inteface.
2460 * Fixed a lot silc_parse_nick memory leaks from the client
2461 library in the file lib/silcclient/command.c.
2463 * Changed the silc_server_send_notify_on_channels's `sender'
2464 argument from SilcSocketConnection to SilcClientEntry to
2465 check the sender as entry and not as connection object and not
2466 to send to the client provided as argument. The affected file
2467 is silcd/packet_send.[ch].
2469 * The notify packets that are destined directly to the client used
2470 to not to be processed by the server. Now changed that and the
2471 server processes all notify packets. After relaying the packet
2472 to the client the notify packet is processed in the server.
2474 * The silc_server_free_client_data now checks whether there is
2475 pending outgoing traffic for the client and purges the data to
2476 the network before removing the client entry.
2478 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2481 an client is killed from the SILC Network. Updated the protocol
2484 Added new function silc_server_send_notify_killed to the
2485 silcd/packet_send.[ch].
2487 * Added function silc_server_packet_relay_notify to relay notify
2488 packets that are destined directly to a client. In this case
2489 the server does not process the notify packets but merely relays
2490 it to the client. Affected file silcd/packet_send.[ch].
2492 Added also silc_server_packet_process_relay_notify to check
2493 whereto relay the notify. Affected file is
2494 silcd/packet_receive.[ch].
2496 * Implemented the KILL command to the server.
2500 * Added the backup schema desgined last fall to the protocol
2501 specs for everyone to see. The specification is in the
2502 *-spec-xx.txt draft and the packet type definitions for the
2503 backup routers is in *-pp-xx.txt draft. Thusly, added also
2504 new packet type SILC_PACKET_CELL_ROUTERS.
2506 * A big security problem in the implementation discovered. The
2507 signoff of an client did not cause new channel key generation
2508 which it of course should've done. The channel keys must be
2509 always re-generated when client leaves (or signoffs) the channel.
2510 The silc_server_remove_from_channels funtion now handles
2511 the channel key re-generation.
2513 * Added `sender' argument to the silc_server_send_notify_on_channels
2514 to not to send the client provided as argument. Affected file
2515 silcd/packet_send.[ch].
2517 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Implemented OPER and SILCOPER commands into the server and
2522 * Added silc_auth_verify and silc_auth_verify_data to verify
2523 the authentication directly from the authentication payload.
2524 It supports verifying both passphrase and public key based
2525 authentication. Affected file lib/silccore/silcauth.[ch].
2527 * Added `hash' field to the SilcIDListData structure. It is the
2528 hash negotiated in the SKE protocol. Affected file is
2531 * Slight redesigning of the SilcAuthPayload handling routines.
2532 Do not send SilcPKCS but SilcPublicKey as argument.
2534 * Implemented the public key authentication support to the
2535 serverconfig. The public key is loaded from the provided path
2536 and saved as authentication data to void * pointer. Thus,
2537 changed the unsigned char *auth_data to void *auth_data;
2539 * Fixed SHUTDOWN command to send the reply before the server
2540 is shutdown. :) Affected file silcd/command.c.
2542 * Fixed fatal bug in CONNECT command. The hostname was invalid
2543 memory and server crashed. Affected file silcd/command.c.
2545 * Fixed fatal bug in CLOSE command. The server_entry became
2546 invalid but was referenced later in the command. Affected file
2549 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Fixed fatal bug in failure packet handling. Server ignored
2552 the failure and thus crashed when it came.
2556 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2559 that the command may be executed only once in (about) 2 seconds.
2560 The old SILC_CF_LAG flag is same but allows command bursts up
2561 to five before limiting.
2563 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2564 server code. Various commands now includes the CF_LAG_STRICT
2565 flag to disallow any kind of miss-use of the command.
2567 * Fixed the silc_buffer_unformat to not to allocate any data
2568 if the length of the data is zero. It used to allocate the
2569 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2571 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Changed the format of AdminConnection configuration section
2574 in the server. Added username of the admin to the format.
2575 Affected files silcd/serverconfig.[ch].
2577 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2578 to return admin configuration data by host, username and/or
2581 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Implemented WHOWAS command to the server. Added the functions:
2585 silc_server_command_whowas_parse,
2586 silc_server_command_whowas_send_reply,
2587 silc_server_command_whowas_from_client and
2588 silc_server_command_whowas_from_server
2590 * Added <Client ID> argument to the WHOWAS command reply. Updated
2591 the protocol specs accordingly.
2593 * Implemented WHOWAS command and command_reply to the client
2596 Implemented the WHOWAS printing on the user interface.
2598 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2600 * Added new argument to the WHOWAS command reply, the real name.
2601 It is an optional argument. Updated the protocol specs.
2603 * Added SilcIDCacheDestructor callback that is registered when
2604 the SilcIDCache is allocated. The callback is called when
2605 an cache entry in the ID Cache expires, or is purged from the
2606 cache. Added into lib/silccore/idcache.[ch].
2608 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2609 to destruct the client entries when the cache entry expires.
2610 Other ID Cache's in server and in the client library ignores
2613 * If the ID Cache entry's `expire' field is zero then the entry
2614 never expires. Added boolean `expire' argument to the
2615 silc_idcache_add function in the lib/silccore/idcache.[ch].
2616 If it is TRUE the default expiry value is used.
2618 * Added silc_server_free_client_data_timeout that is registered
2619 when client disconnects. By default for 5 minutes we preserve
2620 the client entry for history - for WHOWAS command.
2622 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Added support to the server to enforce that commands are not
2625 executed more than once in 2 seconds. If server receives
2626 commands from client more frequently, timeout is registered
2627 to process the commands. Affected file silcd/command.c.
2628 Added new function silc_server_command_process_timeout.
2630 * Changed NICK_NOTIFY handling in client library to check that
2631 if the client's nickname was changed, so there is no need to
2632 resolve anything from the server.
2634 * Removed error printing from the WHOIS and IDENTIFY commands.
2635 If error occurs then it is ignored silently in the client library.
2636 The application, however, may map the received error to
2637 human readable error string. The application currently maps
2638 the NO_SUCH_NICKNAME error to string.
2640 * Made the command status message public to the application. Moved
2641 them from lib/silcclient/command_reply.c to
2642 lib/silcclient/command_reply.h. The application can map the
2643 received command status to the string with the
2644 silc_client_command_status_message function.
2646 * Added check to the server to check that client's ID is same
2647 as the Source ID in the packet the client sent. They must
2650 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added dist-bzip hook to the Makefile.am to make bzip2
2653 compressed distributions.
2655 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Server now enforces the maximum length for the nickname and
2658 the channel as protocol specification dictates. 128 bytes for
2659 nickname and 256 bytes for channel name.
2661 * Moved the WHOIS printing to the application. The client libary
2662 does not print out the WHOIS information anymore, the application
2663 must do it. Renamed silc_client_command_reply_whois_print to
2664 the silc_client_command_reply_whois_save.
2666 The client's idle time is also sent to the application now, and
2667 the idle is shown on screen.
2669 * Added silc_client_command_reply_identify_save to save the
2670 received IDENTIFY entries.
2672 * Do not check for channel private keys in message sending and
2673 reception if the channel does not have the PRIVKEY mode set.
2674 Affected file lib/silclient/client_channel.c.
2676 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2679 just surfaced after chaning the JOIN procedure.
2681 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Added silc_client_get_clients_by_list to get client entries
2684 from Client ID list, that is returned for example by JOIN
2685 and USERS command replies. The application should use this
2686 function for example when JOIN command reply is received to
2687 resolve the clients already on the channel (library does not
2688 do that anymore as USERS command reply is not used in the JOIN
2689 procedure anymore). Affected files lib/silcclient/silcapi.h and
2690 lib/silcclient/idlist.c.
2692 * JOIN command reply and USERS command reply returns now SilcBuffer
2693 pointers instead of unsigned char pointers when returning
2694 the client list and mode list.
2696 * Added <Client ID> argument to the JOIN command reply, mainly
2697 for the server to identify for which client the command was
2698 originally sent. Updated protocol specs accordingly.
2700 * Added SilcDlist private_key pointer to the SilcChannelEntry
2701 in the client to support the channel private keys. Affected
2702 file is lib/silcclient/idlist.h.
2704 * Added SilcChannelPrivateKey argument to the function
2705 silc_client_send_channel_message so that application can choose
2706 to use specific private ke if it wants to. If it is not provided,
2707 the normal channel key is used, unless private keys are set.
2708 In this case the first (key that was added first) is used
2709 as the encryption key.
2711 * Implemented the support for channel private key handling.
2712 Implemented the following functions:
2714 silc_client_add_channel_private_key,
2715 silc_client_del_channel_private_keys,
2716 silc_client_del_channel_private_key,
2717 silc_client_list_channel_private_keys and
2718 silc_client_free_channel_private_keys
2720 Affected file lib/silcclient/client_channel.c.
2722 * Added the support for the private keys in the channel message
2723 sending and encryption and in the message reception and
2724 decryption. Affected funtions are
2725 silc_client_send_channel_message and silc_client_channel_message.
2727 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Added SKE's key verify callback to the client library's
2730 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2732 * Removed the statement that server (or router) must send USERS
2733 command reply when joining to the channel so that the client
2734 knows who are on the channel. Instead, the client list and
2735 client's mode list is now sent in the JOIN command reply to the
2736 client who joined channel. This is better solution.
2738 * Added function silc_server_get_users_on_channel and function
2739 silc_server_save_users_on_channel to the silcd/server.[ch].
2741 * Removed function silc_server_command_send_users from the
2744 * Do not show topic on the client library anymore. The topic is
2745 sent in the command reply notify to the application and the
2746 application must show the topic now.
2748 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Added client searching by nickname hash into the IDENTIFY and
2751 WHOIS commands in the server as they were clearly missing from
2752 them. Affected file is silcd/command.c.
2754 * Fixed a bug in private message receiving in the client library.
2755 The remote ID was freed and it wasn't supposed, now it is
2758 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Minor fix to the channel payload; allocate the data area, as it
2761 needs to be of specific length.
2763 * If the key agreement port is zero then the operating
2764 system will define the bound port. Affected files are
2765 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2767 * Added new function silc_channel_payload_decrypt into the file
2768 lib/silccore/silcchannel.[ch].
2770 * Moved the channel message etc, check from silc_packet_decrypt
2771 to applications. The library calls now a generic
2772 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2773 when the packet is either normal or special. This was done to
2774 allow more wide range of checking that was not allowed when
2775 the code was in library. Now applications can do virtually any
2776 checks to the packet and return to the library the decision how
2777 the packet should be processed. Affected files are
2778 lib/silccore/silcpacket.[ch].
2780 Added silc_server_packet_decrypt_check to the server and
2781 silc_client_packet_decrypt_check to the client library.
2783 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2784 to send with specified source and destination information.
2786 * Channel message delivery between routers was broken after the
2787 channel key distribution was fixed earlier. The channel key
2788 was used be to distributed to other routers as well which is not
2789 allowed by the protocol. Now this is fixed and channel keys
2790 really are cell specific and the channel message delivery between
2791 routers comply with the protocol specification.
2793 * Fixed various commands in server to check also the global list
2794 for the channel entry and not just the local list. The affected
2795 file silcd/command.c.
2797 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Added assert()s to buffer formatting and unformatting routines
2800 to assert (if --enable-debug) when error occurs. Affected
2801 file: lib/silcutil/silcbuffmt.c.
2803 * Changed to auto-reconnect to check whether the remote host is
2804 router and register the re-connect timeout if it is. It used
2805 to check that whether we are normal server, but router must do
2806 auto-reconnect with another router as well. Affected file
2809 * Removed the [<key len>] option from CMODE command as the cipher
2810 name decides the key length, nowadays. See the defined ciphers
2811 from the protocol specification.
2813 * Added [<hmac>] option to the CMODE command to define the HMAC
2814 for the channel. Added SILC_CMODE_HMAC channel mode.
2816 * Added [<hmac>] option for the JOIN command so that user can
2817 select which HMAC is used to compute the MACs of the channel
2820 * Added Hmac field to the Channel Message Payload. The integrity
2821 of plaintext channel messages are now protected by computing
2822 MAC of the message and attaching the MAC to the payload. The
2823 MAC is encrypted. Now, it is clear that this causes some
2824 overhead to the size of the packet but rationale for this is that
2825 now the receiver can verify whether the channel message decrypted
2826 correctly and also when private keys are set for the channel the
2827 receiver can decrypt the packet with several keys and check from
2828 the MAC which key decrypted the message correctly.
2830 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2831 lib/silccrypt/silccipher.[ch].
2833 * Added silc_hash_len to return the digest length into the
2834 lib/silcrypt/silchash.[ch].
2836 * Rewrote parts of Silc Channel Payload interface in the
2837 lib/silccore/silcchannel.[ch]. The encode function now also
2838 encrypts the packet and parse function decrypts it.
2840 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Fixed a minor formatting bug in the SKE's key material processing.
2843 It actually might have processed the keys wrong way resulting
2846 * Redefined the mandatory HMAC algorithms and added new algorithms.
2847 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2848 and hmac-md5 truncated to 96 bits. The mandatory is now
2849 hmac-sha1-96. Rest are optional (including the one that used
2850 to be mandatory). Rationale for this is that the truncated HMAC
2851 length is sufficient from security point of view and can actually
2852 make the attack against the HMAC harder. Also, the truncated
2853 HMAC causes less overhead to the packets. See the RFC2104 for
2856 * Added new [hmac] configuration section. The SKE used to use
2857 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2858 is of course wrong. The official names that must be proposed in
2859 the SKE are the ones defined in the protocol specification
2860 (hmac-sha1-96 for example). The user can configure any hmac
2861 using any hash function configured in the [hash] section. At
2862 least, the mandatory must be configured.
2864 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2866 * Added HMAC list to the SKE proposal list. It has now both
2867 hash algorithm list and HMAC list. This makes the protocol
2868 incompatible with previous versions. The SKE now seems to work
2869 the way it is supposed to work, for the first time actually.
2871 * Defined plain Hash algorithms to the protocol specification.
2874 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Implemented support for key agreement packets into the server.
2877 Added functions silc_server_key_agreement and
2878 silc_server_send_key_agreement. Other than these functions,
2879 server has nothing to do with this packet.
2881 * Added support for private message key packets into the server.
2882 Added functions silc_server_private_message_key and
2883 silc_server_send_private_message_key.
2887 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2888 called in the protocol's final callback instead in the END
2889 protocol state. This makes a little more sense and in the same
2890 time in client we can use the same protocol routines for normal
2891 key exchange and to key agreement packet handling as well.
2893 * Added to both client's and server's KE protocol context the
2894 SilcSKEKeyMaterial pointer to save the key material. We will
2895 bring the key material to the protocol's final callback by doing
2896 this. The final callback must free the key material.
2898 * Added SKE's packet_send callback into client's KE protocol
2899 context so that the caller can choose what packet sending function
2900 is used. This way we can use different packet sending when
2901 doing normal SKE when doing key agreement packet handling (in
2902 the key agreement packet handling we do not want to encrypt
2905 * Implemented the responder side of the key agreement routines
2906 in the client. The client can now bind to specified port and
2907 accept incoming key negotiation. The key material is passed
2908 to the application after the protocol is over.
2910 * Implemented the processing of incoming Key Agreement packet
2911 in the client. Added function silc_client_key_agreement to
2914 * Implemented the intiator side of the key agreement routines
2915 in the client. The client can now initiate key agreement with
2916 another remote client. The key material is passed to the
2917 application after the protocol is over.
2919 * Created client_keyagr.c to include all the key agreement
2922 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2923 SILC_TASK_CALLBACK except that it is not static.
2925 * Created client_notify.c and moved the Notify packet handling
2926 from the client.[ch] into that file.
2928 * Created client_prvmsg.c and moved all private message and
2929 private message key routines from the client.[ch] into that file.
2931 * Create client_channel.c and moved all channel message and
2932 channel private key routines from the client.[ch] into that file.
2934 * Changed silc_client_get_client_by_id_resolve to resolve with
2935 WHOIS command instead of IDENTIFY command, in the file
2936 lib/silclient/idlist.c.
2938 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Implemented the SKE's responder side to the Client library.
2942 * When FAILURE is received to the protocol do not trust it
2943 blindly. Register a timeout to wait whether the remote closes
2944 the connection as it should do it, only after that process the
2945 actual failure. This was changed to both client and server.
2947 * Added client_internal.h to include some of the structures
2948 there instead of client.h in lib/silcclient/.
2950 * Added function silc_task_unregister_by_callback to unregister
2951 timeouts by the callback function.
2953 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2955 * Some "Incomplete WHOIS info" errors has been appearing on the
2956 log files. Took away the entry->userinfo check from WHOIS
2957 reply sending. The entry->userinfo is now " " if client did not
2958 provide one. I thought this was fixed earlier but something
2959 is wrong still. Let's see if the error still appears.
2961 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Fixed a minor bug in the login when the channel key is
2964 re-generated in the server. It used to generate the key in
2965 wrong order and thus caused problems in the channel traffic.
2967 * Fixed a minor bug in channel key distsribution after
2968 KICK command. The key was not sent to the router even though
2971 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added silc_ske_process_key_material_data as generic routine
2974 to process any key material as the SILC protocol dictates. The
2975 function is used by the actual SKE library but can be used by
2976 applications as well. This relates to the private message keys
2977 and the channel private keys since they must be processed the
2978 same way the normal SILC session keys. The protocol dictates
2979 this. Affected files: lib/silcske/silcske.[ch].
2981 Added also silc_ske_free_key_material to free the
2982 SilcSKEKeyMaterial structure.
2984 * Defined silc_cipher_set_key function to set the key for
2985 cipher without using the object's method function. The affected
2986 files: lib/silccrypt/silccipher.[ch].
2988 * Implemented silc silc_client_add_private_message_key,
2989 silc_client_add_private_message_key_ske,
2990 silc_client_del_private_message_key,
2991 silc_client_list_private_message_keys and
2992 silc_client_free_private_message_keys functions in the
2995 Added functions silc_client_send_private_message_key to send
2996 the Private Message Key payload and silc_client_private_message_key
2997 to handle incoming Private Message Key payload.
2999 * Added Cipher field to the Private Message Key payload to set
3000 the cipher to be used. If ignored, the default cipher defined
3001 in the SILC protocol (aes-256-cbc) is used.
3003 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Removed lib/silcclient/ops.h file.
3007 Redefined parts of the SILC Client Library API. Created new
3008 file silcapi.h that deprecates the ops.h file and defines the
3009 published Client Library API. Defined also private message key
3010 API and channel private key API into the file.
3012 This is the file that the application must include from the
3013 SILC Client Library. Other files need not be included by
3014 the application anymore.
3016 * Added new key_agreement client operation callback and also
3017 defined the Key Agreement library API for the application.
3019 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3022 is used by clients to request key negotiation between another
3023 client in the SILC network. If the negotiation is started it
3024 is performed using the SKE protocol. The result of the
3025 negotiation, the secret key material, can be used for example
3026 as private message key.
3028 Implemented the Key Agreement payload into the files
3029 lib/silccore/silauth.[ch].
3031 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Redefined ciphers for the SILC protocol. Added some new ciphers
3034 and defined the key lengths for the algorithms. Changed the
3035 code accordingly. The default key length is now 256 bits.
3037 * Fixed SKE key distribution function silc_ske_process_key_material
3038 when the key length is more than 128 bits. The default key
3039 length in SILC is now 256 bits.
3041 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3042 to indicate unsupported algorithm.
3044 * Renamed rijndael.c to aes.c and all functions as well.
3046 * Fixed a long standing channel key setting bug in client library.
3047 Weird that it has never surfaced before.
3049 * Fixed bug in channel deletion. If the entire channel is removed
3050 then it must also delete the references of the channel entry
3051 from the client's channel list as the client's channel entry and
3052 the channel's client entry share same memory.
3054 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Implemented CONNECT and SHUTDOWN commands in the client.
3058 * Implemented CLOSE command to the client.
3060 * Added the function silc_idlist_find_server_by_name into the
3061 files silcd/idlist.[ch].
3063 Added the function silc_idlist_find_server_by_conn into the
3064 files silcd/idlist.[ch].
3066 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * DIE command was renamed to SHUTDOWN. Updated the both code
3071 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3072 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3074 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3077 * Added function silc_server_create_connection function to create
3078 connection to remote router. My server implementation actually
3079 does not allow router to connect to normal server (it expects
3080 that normal server always initiates the connection to the router)
3081 so the CONNECT command is only good for connecting to another
3084 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3087 or some other client was kicked from the channel.
3089 Implemented the handling of the notify type to both client
3092 Implemented silc_server_send_notify_kicked to send the KICKED
3093 notify. It is used to send it to the server's primary router.
3095 * Implemented the KICK command into server and client.
3097 * Added `query' argument to the silc_idlist_get_client function
3098 to indicate whether to query the client from server or not if
3101 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3102 to indicate that the client is not channel founder.
3106 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Removed the rng context from SilcPacketContext structure and
3109 changed that the packet routine uses the Global RNG API.
3111 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Added support for quit message that client can "leave" on the
3114 channel when it quits the SILC. It is ditributed inside the
3115 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3117 Added silc_server_free_client_data that will take the
3118 signoff message as argument.
3120 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3122 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Updated parts of the protocol specification to keep it up
3127 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3130 payloads in one packet.
3132 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3133 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3134 use now the new List flag.
3136 * Also deprecated the following packet types: REPLACE_ID,
3137 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3139 * Added list support for Notify packet in server.
3141 * Added silc_server_send_notify_channel_change to send the
3142 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3143 the silc_server_send_replace_id.
3145 * Added silc_server_send_notify_nick_change to send the
3146 NICK_CHANGE notify type. Deprecates the function
3147 silc_server_send_replace_id.
3149 * Added silc_server_send_notify_join to send the JOIN notify type.
3150 Deprecates the function silc_server_send_new_channel_user.
3152 * Added silc_server_send_notify_leave to send LEAVE notify type.
3153 Deprecates the function silc_server_send_remove_channel_user.
3155 * Added silc_server_send_notify_cmode and
3156 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3157 types. Deprecates the silc_server_send_set_mode function.
3159 * Added SERVER_SIGNOFF notify type to indicate that server has
3160 quit. This means that all clients on the channel from that
3161 server will drop. This can be also used when netsplit happens.
3163 Deprecated REMOVE_ID packet type since it is not needed anymore
3166 Added silc_server_send_notify_server_signoff to send the
3167 SERVER_SIGNOFF notify type. Deprecates the function
3168 silc_server_send_remove_id.
3170 Added also silc_server_send_notify_signoff to send the
3171 SIGNOFF notify type.
3173 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3174 SILC protocol from this day on. Changed the protocol
3175 specification as well.
3177 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3178 notify type. It is used between routers to notify about
3179 topic changes on a channel.
3181 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3184 * Partly updated the protocol specification to comply with the
3185 changes now made. It is still though a bit outdated.
3187 * The JOIN notify type now takes one extra argument <Channel ID>.
3188 The packet used to be destined to the channel but now the
3189 JOIN type may be sent as list thus it is impossible to
3190 destine it to any specific channel. By adding this argument
3191 it is again possible.
3193 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Added CREDITS file. The CHANGES and CREDITS file will appear
3196 in the distribution as well.
3198 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3201 types in the server's silcd/packet_receive.c.
3203 * Implemented CMODE and CUMODE to work in router environment.
3205 * Fixed minor encoding and decoding buglet from the
3206 lib/silccore/silcmode.c.
3208 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3211 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3213 * Changed all SilcConfigServer* and silc_config_server* to
3214 SilcServerConfig* and silc_server_config*, respectively.
3217 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Associated the ID (client or server ID) to the Authentication
3220 Payload to avoid any possibility of forging. Updated the
3221 protocol specification and the code accordingly.
3223 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * The RSA key length is now save to the RsaKey context in the
3226 key generation process in lib/silccrypt/rsa.c. The key length
3227 is now used to figure out the maximum size of the block allowed
3228 to be encrypted/signed.
3230 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3231 is equivalent to the silc_mp_mp2bin but does not allocate any
3234 * Changed silc_mp_mp2bin API to take length argument. If it is
3235 non-zero then the buffer is allocated that large. If zero, then
3236 the size is approximated using silc_mp_sizeinbase, which however
3239 * Created Global RNG API which is global RNG that application can
3240 initialize. After initializing, any routine anywhere in the
3241 code (including library) can use RNG without allocating a new
3242 RNG object. This was done to allow this sort of use of the
3243 RNG in code that has no chance to allocate RNG object. All
3244 applications currently allocate this and many routines in the
3245 library use this. Affected file lib/silccrypt/silcrng.[ch].
3247 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3248 it to use the Global RNG API.
3250 * Defined Authentication Payload into protocol specification that
3251 is used during SILC session to authenticate entities. It is
3252 used for example by client to authenticate itself to the server
3253 to obtain server operator privileges.
3255 Implemented this payload into the lib/silccore/silcauth.[ch].
3256 Implemented also routines for public key based authentication
3257 as the new protocol specification dictates.
3259 Moved definitions of different authentication methods from
3260 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3262 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3263 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3264 silc_pkcs_verify_with_hash functions into the file
3265 lib/silccrypt/silcpkcs.[ch].
3267 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * The client entry's userinfo pointer must be always valid.
3270 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3271 will fail since it requires the userinfo. Now, the userinfo
3272 is allocated as "" if actual userinfo does not exist. Actually,
3273 it must exist and it is totally Ok to drop client connections
3274 that does not announce the userinfo. However, we will make
3275 this workaround for now.
3277 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3278 to return the remote port by socket.
3280 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3283 SILC_SERVER_PENDING_EXEC and added an new macro
3284 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3285 data or when error occurs while processing the pending command.
3287 Added new argument `destructor' into silc_server_command_pending
3288 and to the SilcServerCommandPending object. This destructor is
3289 now called after calling the pending callback or if error occurs
3290 immediately. If error occurs the actual pending callback won't
3291 be called at all - only the destructor. The destructor may be
3292 NULL if destructor is not needed.
3294 All this applies for client library code as well. Similar
3295 changes were made there as well for the pending commands.
3297 In the client, the application must now allocate the
3298 SilcClientCommandContext with the silc_client_command_alloc
3301 * Added reference counter to the SilcServerCommandContext. Added
3302 function silc_server_command_alloc and silc_server_command_dup
3305 Same type of functions added to the client library for the same
3308 * Removed the cmd_ident from IDListData away since it is now
3309 global for all connections. It is the command identifier used
3310 in command sending and with pending commands. The affected file
3313 * Added reference counter to the SilcSocketConnection objecet to
3314 indicate the usage count of the object. The object won't be
3315 freed untill the reference counter hits zero. Currently only
3316 server uses this, and client ignores it. The client must be
3317 set to use this too later. The affected files are
3318 lib/silccore/silcsockconn.[ch]. Added also the function
3319 silc_socket_dup to increase the reference counter.
3321 This was mainly added because it is possible that the socket
3322 is removed underneath of pending command or other async
3323 operation. Now it won't be free'd and proper DISCONNECTING
3324 flags, etc. can be set to avoid sending data to connection that
3325 is not valid anymore.
3327 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3328 the connection. After that it sets SILC_SET_DISCONNECTED.
3329 It is, however, possible that the socket data is not still freed.
3330 The silc_server_packet_process now checks that data is not
3331 read or written to connection that is DISCONNECTED. The socket
3332 get's freed when the reference counter hits zero.
3334 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Changed the client operation API: channel_message operation's
3337 `sender' is now the client entry of the sender, not the nickname
3338 and the `channel' is the channel entry, not the channel name.
3340 In the private_message operation the `sender' is now also the
3341 client entry of the sender not the nickname.
3343 Affected file is lib/silcclient/ops.h and all applications
3344 using the client operations.
3346 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Moved the calling of ops->connect() from connect_to_server_final
3349 into receive_new_id functin since that is the point when the
3350 client is actually allowed to send traffic to network. The
3351 affected file is lib/silcclient/client.c.
3353 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3356 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3357 (if needs broadcasting) instead of broadcasting the packets one
3358 by one which would make a burst in the network traffic.
3360 * Added `broadcast' argument to the functions in silcd/server.[ch]
3361 silc_server_create_new_channel[_with_id] to indicate whether
3362 to send New Channel packet to primary router.
3364 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * Added new function into the silcd/server.[ch] files:
3367 silc_server_create_new_channel_with_id to create new channel with
3368 already existing Channel ID.
3370 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3371 lib/silccore/silcpacket.h. This packet is used t send list of
3372 Set Mode payloads inside one packet. Server uses this to set
3373 the modes for the channels and clients on those channels, that it
3374 announced to the router when it connected to it. The protocol
3375 specification has been updated accordingly.
3377 * The silc_server_new_channel did not handle the packet coming
3378 from normal server as it normally does not send that. However,
3379 when it announces its channels it does send it. Implemented
3380 the support for that.
3382 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3383 into the file lib/silccore/id.h.
3385 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Fixed memory leaks in the functions silc_idlist_del_client,
3388 silc_idlist_del_channel and silc_idlist_del_server in the file
3389 silcd/idlist.c. All of those leaked like a sieve.
3391 * Fixed some small memory leaks in the client's function
3392 silc_client_notify_by_server.
3394 * Added functions into silcd/server.c: silc_server_announce_clients,
3395 silc_server_announce_channels and silc_server_announce_server.
3396 These functions are used by normal and router server to announce
3397 to its primary router about clients, channels and servers (when
3398 router) that we own. This is done after we've connected to the
3401 These functions effectively implements the following packet types:
3402 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3403 and SILC_PACKET_NEW_ID_LIST.
3405 * Added new functions into the silcd/packet_receive.[ch]:
3406 silc_server_new_id_list, silc_server_new_channel_list and
3407 silc_server_new_channel_user_list to handle the incoming
3408 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3410 * Added support of changing Channel ID in the function
3411 silc_server_replace_id. If the server that announces a channel
3412 to the router already exists in the router (with same name but
3413 with different Channel ID), router is responsible to send
3414 Replace ID packet to the server and force the server to change
3415 the Channel ID to the one router has.
3417 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3418 client that the Channel ID has been changed by the router. The
3419 normal server sends this to the client. Client must start using
3420 the new Channel ID as the channel's ID.
3422 Implemented handling of this new type into lib/silcclient/client.c
3423 into the function silc_client_notify_by_server.
3425 * Added new function silc_idlist_replace_channel_id into the files
3426 silcd/idlist.[ch] to replace the Channel ID.
3428 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Call silc_server_command_identify_check always when processing
3431 the IDENTIFY command in silcd/command.c
3433 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3436 send keepalive packets. The packet can be sent by clients,
3437 servers and routers.
3439 Added function silc_socket_set_heartbeat into the file
3440 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3441 If not set, the heartbeat is not performed. The actual
3442 heartbeat is implemented in the low level socket connection
3443 library. However, application is responsible of actually
3446 Added silc_server_send_heartbeat to send the actual heartbeat
3447 packet into silcd/packet_send.[ch]. Server now performs
3448 keepalive with all connections.
3450 * Added silc_task_get_first function into lib/silcutil/silctask.c
3451 to return the timeout task with shortest timeout. There was a bug
3452 in task unregistration that caused problems. TODO has been
3453 updated to include that task system must be rewritten.
3455 * The client library will now resolve the client information when
3456 receiving JOIN notify from server for client that we know but
3457 have incomplete information.
3459 * Rewrote parts of silc_server_remove_from_channels and
3460 silc_server_remove_from_one_channel as they did not remove the
3461 channel in some circumstances even though they should've.
3463 * Encryption problem encountered in server:
3465 The LEAVE command used to send the Channel Key packet to the
3466 router immediately after generating it. However, the code
3467 had earlier sent Remove Channel user packet but not immediately,
3468 ie. it was put to queue. The order of packets in the router
3469 was that Channel Key packet was first and Remove Channel User
3470 packet was second, even though they were encrypted in the
3471 reverse order. For this reason, MAC check failed. Now, this
3472 is fixed by not sending the Channel Key packet immediately but
3473 putting it to queue. However, this is more fundamental problem:
3474 packets that are in queue should actually not be encrypted
3475 because packets that are sent immediately gets encrypted
3476 actually with wrong IV (and thus MAC check fails). So, packets
3477 that are in queue should be encrypted when they are sent to
3478 the wire and not when they put to the queue.
3480 However, the problem is that the current system has not been
3481 designed to work that way. Instead, the packet is encrypted
3482 as soon as possible and left to the queue. The queue is then
3483 just purged into wire. There won't be any fixes for this
3484 any time soon. So, the current semantic for packet sending
3487 o If you send packet to remote host and do not force the send
3488 (the packet will be in queue) then all subsequent packets to the
3489 same remote host must also be put to the queue. Only after the
3490 queue has been purged is it safe again to force the packet
3493 o If you send all packets immediately then it safe to send
3494 any of subsequent packets through the queue, however, after
3495 the first packet is put to queue then any subsequent packets
3496 must also be put to the queue.
3498 Follow these rules and everything works fine.
3500 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Added new function silc_server_remove_clients_by_server to
3503 remove all client entries from ID list when the server connection
3504 is lost. In this case it is also important to invalidate all
3505 client entires as they hold the invalid server entry. This
3506 fixes fatal bug when server has lost connection and will reconnect
3509 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Made some sanity checks to silc_server_daemonise like to check
3512 whether the requested user and group actually exists.
3514 * Added sanity check to SKE's silc_ske_responder_finish to check
3515 that the public and private key actually is valid.
3517 * Invalidate the client's nickname when receiving Replace ID
3518 packet and the Client ID is being replaced. This means that the
3519 server will query the nickname if someone needs it (client)
3522 * Sort the ID Cache in client library when the ID Cache data
3523 has changed (needs sorting).
3525 * Do not allow for SILC client to create several connections to
3526 several servers. The client does not support windows right now
3527 and generating multiple connections causes weird behaviour.
3529 Irssi-silc client does support windows and can handle several
3530 connections without problems, see: www.irssi.org and SILC plugin.
3532 * Fixed some places where client was added to the IDList. The
3533 rule of thumb is following (in order to get everything right):
3534 If the client is directly connected local client then the
3535 `connection' argument must be set and `router' argument must be
3536 NULL to silc_idlist_add_client function. If the client is not
3537 directly connected client then the `router' argument must
3538 bet set and the `connection' argument must be NULL to the
3539 silc_idlist_add_client function.
3541 * The funtion silc_server_packet_send_local_channel actually did
3542 not check whether the client was locally connected or not. It
3543 does that now. Fixed a bug related to LEAVE command.
3545 * Fixed Remove Channel User payload parsing bug in server's
3546 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3548 * The server's silc_server_save_channel_key now checks also the
3549 global ID list for the channel as it might not be in the local
3550 list. Fixed a bug related to LEAVE command.
3552 * Is this the end of the [<unknown>] buglet that has been lurking
3553 around for a long time? A little for loop fix in server's
3554 silc_server_command_whois_parse that is used by both IDENTIFY
3555 and WHOIS command. At least, this was a clear bug and a cause
3556 of one type of [<unknown>] buglet.
3558 * WHOIS and IDENTIFY commands call the function
3559 silc_server_command_[whois/identify]_check function even if
3560 we are not router server.
3562 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Added --with-gmp configuration option. If set the GMP
3565 is always compiled in the SILC source tree. If not set then
3566 it is checked whether the system has the GMP3 installed. If
3567 it has then the GMP won't be compiled (the system's headers
3568 and library is used), if it doesn't have it then the GMP is
3569 compiled in the SILC source tree.
3571 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Changed RSA private exponent generation to what PKCS #1
3574 suggests. We try to find the smallest possible d by doing
3575 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3576 not security fix but optimization.
3578 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Added new config entry [Identity] to fork the server and run
3581 it as specific user and group. A patch from Bostik.
3583 * Imported Dotconf configuration library into lib/dotconf.
3584 This will be used to create the SILC configuration files later.
3585 It will appear in the distsribution after this commit.
3587 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * A big code auditing weekend happening. Auditing code for
3590 obvious mistakes, bugs and errors. Also, removing any code
3593 Removed files for being obsolete:
3595 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3596 inline in the file lib/silcutil/silcbuffer.h)
3598 o lib/silcutil/silcbufutil.c (the header has inline versions)
3600 Changed code to fix possible error conditions:
3602 o The buffer formatting routines now check that the destination
3603 buffer really has enough space to add the data. This applies for
3604 both buffer formatting and unformatting
3605 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3606 unformatting was changed to accomodate following rules:
3607 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3608 sent to the function while XXX_*STRING will not allocate or copy
3609 the data into the buffer. Instead it sets the pointer from the
3610 buffer into the pointer sent as argument (XXX_*STRING used to
3611 require that the pointer must be allocated already). This change
3612 makes this whole thing a bit more consistent and more optimized
3613 (note that the data returned in the unformatting with XXX_*STRING
3614 must not be freed now). The routines return now -1 on error.
3616 o Tried to find all code that use buffer_format and buffer_unformat
3617 and added return value checking to prevent formatting and
3618 especially unformatting errors and possible subsequent fatal
3621 o Changed ske->x and ske->KEY to mallocated pointers in
3622 lib/silcske/silcske.h. Fixed possible data and memory leak.
3624 o Added return value checking to all *_parse* functions. Fixed
3625 many memory leaks as well.
3627 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3628 so that buffer overflows would not happen. All code now also
3629 checks the return value as it can fail.
3631 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Added reconnection support to server if the normal server looses
3634 its connection to the router (for example if router is rebooted).
3635 The server performs normal reconnection strategy implemented
3636 to the server. Affected file silcd/server.c.
3638 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Added new packet type SILC_PACKET_SET_MODE that is used to
3641 distribute the information about changed modes (for clients,
3642 channels and clients channel modes) to all routers in the
3643 network. Updated the protocol specification accordingly.
3645 Added functions into silcd/packet_send.c and
3646 silcd/packet_receive.c: silc_server_send_set_mode,
3647 silc_server_set_mode.
3649 Added new files silcmode.[ch] into lib/silccore that implements
3650 the encoding and decoding of Set Mode Payload. Added new type
3651 SilcSetModePayload. Moved the definitions of different modes
3652 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3654 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Oops, a little mistake in server's connection authentication
3657 protocol. The protocol is not ended with FAILURE but with
3658 SUCCESS if the authentication is Ok. :) Affected file is
3661 * Implemented NICK_CHANGE notify handling in server in the file
3662 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3663 the local clients on the channel. After the changing nickname
3664 in router environment snhould work and the [<unknown>] nickname
3665 should appear no more.
3667 The silc_server_replace_id function that receives the Replace ID
3668 payload now sends the NICK_CHANGE notify type also in the file
3669 silcd/packet_receive.c
3671 * Changed WHOIS and IDENTIFY command to support the maximum amount
3672 of arguments defined in protocol specs (3328 arguments). This
3673 fixed a bug that caused problems when there were more than three
3676 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Added extra parameter, command identifier, to the
3679 silc_client_send_command so that explicit command identifier
3682 Changed that ID list routines uses specific command identifier
3683 when sending WHOIS/IDENTIFY requests to the server so that they
3684 can be identified when the reply comes back.
3686 Affected files lib/silcclient/command.[ch],
3687 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3689 * Added `sender' argument to silc_server_packet_send_to_channel
3690 to indicaet the sender who originally sent the packet to us
3691 that we are now re-sending. Ignored if NULL. Affected file
3692 silcd/packet_send.[ch].
3694 * Added some server statistics support in silcd/server_internal.h
3695 SilcServerStatistics structure and around the server code. Also
3696 send some nice statistics information when client is connecting
3699 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Fixed channel ID decoding in server's JOIN command reply in
3702 silcd/command_reply.c
3704 * Fixed braodcasting of replace ID payload to not to send it if
3705 we are standalone server in silcd/packet_receive.c.
3707 * Fixed all channel message sending routines to not to send
3708 packets to clients that has router set, since they are routed
3709 separately in the same function earlier. Affects file
3710 silcd/packet_send.c and all channel packet sending functions.
3712 * In USERS reply, res_argv[i] are not allocated, the table
3713 is allocated. Thus changed that free the table, not its
3716 * In server's whois_check and identify_check if the client is
3717 locally connected do not send any WHOIS commands - they are not
3720 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Fixed some minor bugs in client when sending WHOIS command. The
3723 arguments was in wrong order.
3725 * Removed statis function add_to_channel from server in
3726 silcd/command.c that was previously used with the joining but
3729 * Tested USERS command in router environment successfully with two
3730 routers, two servers and two clients.
3732 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Reorganized the USERS command and command reply in client library
3735 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3736 When the command is given by user we register a pending command
3737 callback that will reprocess the command after the reply has been
3738 received from the server. When reprocessing the packet we then
3739 display the information. Thus, the USERS information is displayed
3740 now in the command callback instead of in the command reply
3741 callback. The processing of the command is same as previously
3742 when server has sent the command reply in the JOINing process.
3744 * Added to USERS command in silcd/command_reply.c to join the client,
3745 we didn't use to know about, to the channel after we've created
3746 a client entry for it. Also, for clienet we did know already still
3747 check whether it is on the channel or not and add it if not.
3749 * Removed silc_server_command_join_notify as the function and its
3752 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Changed the client's pending command handling to the same as the
3755 server's pending command handling. It is also now possible to
3756 execute command reply functions from other command reply
3757 function as the function callbacks for commands and command
3758 replies are one and same. The pending commands are not static
3759 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3760 in client connection context. Thus, pending commands are server
3761 connection specific as it is convenient.
3763 Changed the function silc_client_command_pending and
3764 silc_client_command_pending_del and added new function
3765 silc_client_command_pending_check. Removed the
3766 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3769 * Added cmd_ident, current command identifier, to the client
3770 connection context in lib/silcclient/client.h to keep track on
3771 command identifiers used in command sending. Client's command reply
3772 function handling now supports the mandatory command identifiers.
3774 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3775 funtions in client to fully support pending command callbacks.
3777 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3778 as one of the arguments to the application in the command reply
3781 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3782 before first releasing SILC but came back. Now it is removed again
3783 and should come back nomore. The FORWARDED flag was used only
3784 by the JOINing procedure by forwarding the command packet to router.
3785 Now, the JOINing procedure has been changed to more generic (due
3786 to various router environment issues) and FORWARDED is not needed
3787 anymore for anything. The protocol specification is yet to be
3790 Now, removed silc_server_packet_forward from server and the flag
3791 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3793 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Renamed NAMES command to USERS command. The NAMES was named that
3796 due to historical reasons. Now it is renamed. Also, rewrote
3797 parts of the USERS command. The nickname list is not sent anymore
3798 by the server. Only Client ID and mode lists are sent in the USERS
3799 command. Changed this also to the protocol specification.
3801 The client now resolves the names and stuff after it receives
3802 the USERS list from the server when joining to the channel.
3804 * WHOIS and IDENTIFY commands has been changed to support multiple
3805 Client ID's per command. One can now search for multiple users
3806 in the network by sending only one WHOIS or IDENTIFY command.
3807 Changed the code and the protocol specifications.
3809 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3810 uses silc_server_command_whois_parse to parse the request. */
3812 * If normal server, do not parse the WHOIS and IDENTIFY requests
3813 before sending it to the router. Saves some time.
3815 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Fixed JOIN command on client library. Wrong number of arguments
3818 used to crash the client.
3820 * Added silc_server_channel_has_global function to check whether
3821 channel has global users or not.
3823 * Added silc_server_channel_has_local function to check whether channel
3824 has locally connected clients on the channel.
3826 * The silc_server_remove_from_one_channel now checks whether the
3827 channel has global users or not after given client was removed from
3828 the channel. It also checks whether the channel has local clients
3829 on the channel anymore. If it does not have then the channel entry
3830 is removed as it is not needed anymore.
3832 * The silc_server_notify now checks on JOIN notify whether the joining
3833 client is one of locally connected or global. If it is global then
3834 the channel has now global users on the channel and that is marked
3835 to the channel entry. Also, it now saves the global client to
3836 global list who is joining and JOINs it to the channel. This is
3837 for normal server, that is.
3839 Changed silc_server_send_notify_on_channel,
3840 silc_server_packet_relay_to_channel and
3841 silc_server_packet_send_to_channel check if we are normal server
3842 and client has router set (ie. global client) do not send the
3843 message to that client, as it is already routed to our router.
3845 * Implemented LEAVE notify type handling in silc_server_notify
3848 * Tested LEAVE command in router environment successfully. Tested
3849 with two routers, two servers and two clients.
3853 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3855 * Implemented SIGNOFF notify type handling in silc_server_notify
3858 * silc_server_remove_id now removes the client entry from all channels
3859 it has joined and thusly sends SIGNOFF notify type.
3861 * Rewrote the NAMES list generation in server by removing two excess
3862 loops. The lists are created now inside one loop.
3864 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * silc_server_remove_channel_user checks now also global list
3867 for channel and client.
3869 * silc_server_new_channel_user checks now both local and global
3870 list for channel and client. Fixed a bug in client id decoding.
3871 Used to decode wrong buffer.
3873 * silc_server_channel_message checks now both local and global
3874 list for channel entry.
3876 * Tested channel joining (hence JOIN) in router environment
3877 successfully. Tested with two routers, two servers and two
3880 * Tested channel message sending in router environment successfully.
3882 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Added silc_server_save_channel_key into server.[ch] to save the
3885 received channel key in Channel Key payload processing. It is
3886 also used in JOIN command reply handling.
3888 Equivalent function silc_client_save_channel_key added into
3889 client.[ch] into client library.
3891 * Changed JOIN command reply to send information whether the channel
3892 was created or not (is existing already) and the channel key
3893 payload. Changed protocol specs accordingly.
3895 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3896 the request was sent by ID and not by nickname. Crashed on
3899 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3902 now correctly save the received data.
3904 * silc_server_free_sock_user_data now notifies routers in the
3905 network about entities leaving the network.
3907 At the same time implemented functions silc_server_remove_id
3908 and silc_server_send_remove_id to receive and send REMOVE_ID
3909 packets. The packet is used to notify routers in the network
3910 about leaving entities. The ID removed will become invalid in
3913 * Added function silc_idlist_del_server into server. Removes and
3914 free's server entry from ID list.
3916 * silc_server_private_message function now checks, if we are router,
3917 that the destination ID really is valid ID, naturally.
3919 * In router when NEW_ID packet is received (for new client) the
3920 hash of the Client ID is saved in the ID Cache but the
3921 client->nickname is set to NULL, instead of putting the hash
3924 IDENTIFY command now also checks that client->nickname must be
3925 valid. If it is not if will request the data from the server who
3926 owns the client. Added new function
3927 silc_server_command_identify_check.
3929 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3930 to set the command to already allocated Command Payload.
3932 * Tested private message sending in router environment with two
3933 routers, two servers and two clients. Fixed minor bugs and now
3936 * Fixed segfault from client's NAMES command. Used to crash if
3939 * Forwarded packets must not be routed even if it is not destined
3940 to the receiver. Changed server code comply with this.
3942 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Added `require_reverse_mapping' boolean value to ServerParams
3945 structure. If TRUE (not default) the server will require that
3946 the connecting host has fully qualified domain name.
3948 If the reverse mapping is not required and hostname could not be
3949 found the IP address is used as hostname.
3951 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Implemented version string checking to both client and server.
3954 The check is incomplete currently due to the abnormal version
3955 strings used in development version of SILC.
3957 * Changed all command functions in server to use the new
3960 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Changed char *data to unsigned char *data in ID Cache system to
3963 support binary data as ID Cache data. Changed code to support
3964 binary data in lib/silccore/idcache.c.
3966 * Renamed silc_server_packet_relay_command_reply to
3967 silc_server_command_reply as it is normal packet receiving
3968 function. Rewrote the function to accept command replys for
3969 servers and not only for clients.
3971 * Mark remote router always as registered server if we are connecting
3972 to it. Otherwise, commands sent by the router to us are ignored.
3974 * All ID List find routines now returns the ID Cache Entry pointer
3975 as well if requested.
3977 * WHOIS command works now in router environment, tested with two
3978 routers, two servers and two clients.
3980 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3981 in router environment (as it is almost equivalent to WHOIS) but
3982 hasn't been tested thoroughly. Added new functions:
3984 silc_server_command_identify_parse
3985 silc_server_command_identify_send_reply
3986 silc_server_command_identify_from_client
3987 silc_server_command_identify_from_server
3989 * Disabled route cache adding because adding two different ID's with
3990 same IP replaces the old cache entry thus giving wrong route.
3991 The entry->router->connection is always the fastest route anyway
3992 so route cache may not be needed. Of course, new routes maybe
3993 established after receiving the ID when the entry->router->connection
3994 might not be anymore the most optimal.
3996 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Add route cache for received ID for fast routing.
4000 * Added silc_server_packet_route to route received packet on router
4001 that is not destined to us.
4003 * Renamed silc_server_get_route to silc_server_route_get.
4005 * Added id_string and id_string_len fields into SilcServer to
4006 include encoded ServerID for fast comparing without excess
4007 encoding of the ID's.
4009 * Cleaned up WHOIS command on server side. Added following static
4012 silc_server_command_whois_parse
4013 silc_server_command_whois_check
4014 silc_server_command_whois_send_reply
4015 silc_server_command_whois_from_client
4016 silc_server_command_whois_from_server
4018 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4019 arguments in command replies. All command functions should be
4020 updated to use this macro.
4022 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Minor typo fixes on command reply handling on server.
4026 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Added silc_server_command_add_to_channel internal routine to add
4029 the client to the channel after router has created the channel and
4030 sent command reply to the server.
4032 * Added generic silc_server_send_command to send any command from
4035 * Use static buffer with ID rendering instead of duplicating data.
4037 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Fixed a channel user mode bug when joining to a channel server gave
4040 everybody channel founder rights, oops.
4042 * We mark ourselves as the router of the incoming server connection
4043 if we are router ourselves. This way we can check in some packet
4044 sending functions whether it is locally connected server. For
4045 incoming router connections we put NULL.
4047 * For router sending packets locally means now always sending the
4048 packet cell wide; to local clients and local servers. For normal
4049 server sending packet locally means sending it to only local
4052 * Fixed the JOIN command to really work in router environment. If the
4053 channel is created it is always created by the router. Router is
4054 also responsible of making the initial joining to the channel,
4055 sending JOIN notify to the sending server and distributing
4056 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4057 does not exist server doesn't do anything else but forward the
4058 command to the router which performs everything.
4060 * Added silc_server_send_channel_key function to send the Channel Key
4063 * Added silc_server_create_channel_key to create new channel key. The
4064 channel key is now re-generated everytime someone joins or leaves
4065 a channel, as protocol dictates. Note: channel->key_len is the
4068 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4071 packet_receive.[ch] to separate packet sending and receiving
4072 routines. The server.[ch] now includes everything else including
4073 actual packet processing (writing and reading data) and other
4076 Renamed silc_server_private_message_send_internal to
4077 silc_server_send_private_message. The routine is still though
4078 used only to relay private messages as server does not send
4079 private messages itself.
4081 Renamed silc_server_new_channel to silc_server_create_new_channel
4082 and added new function sicl_server_new_channel that handles the
4083 incoming New Channel packet. Added also new sending function
4084 silc_server_send_new_channel to send New Channel Payload.
4086 * Added new function silc_server_notify to process incoming notify
4087 packet to the server/router. Server may then relay the notify
4088 to clients if needed.
4090 * Added new function silc_server_new_channel_user to process incoming
4091 New Channel User packet. Router will redistribute the packet and
4092 send JOIN notify to its local clients and locally connected servers
4093 if needed. Normal server will send JOIN notify to its local client
4094 on same channel when received this packet. Added also corresponding
4095 sending function silc_server_send_new_channel_user to sent the
4098 * Added boolean route argument to send_notif_to_channel and
4099 packet_send_to_channel functions to attempt to route the packet
4100 if it is TRUE and send only locally if it is FALSE.
4102 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * silc_server_replace_id now broadcasts the received replace ID
4105 packet if it is not broadcast packet already. The router must
4106 broadcast to inform other routers about changed ID.
4108 * Added backpointer to server's router into SilcServer context in
4109 silcd/server_internal.h.
4111 * Fixed silc_server_packet_broadcast to send correct broadcast
4114 * The channel key is now distributed to the local client as soon
4115 as it is received from the router (in router environment) so that
4116 no other packet may be sent for the channel until client has
4119 * silc_server_remove_channel_user now broadcasts the received
4120 Remove Channel User packet if it is not broadcast packet already.
4121 The router must broadcast to inform other routers about removed
4124 * Added users field into SilcPacketContext that is a reference count
4125 of the context. One can increase the reference count by calling
4126 silc_packet_context_dup which is now changed to just increase the
4127 reference count instead of duplicating the data. The reference
4128 count is decresed by calling silc_packet_context_free that will
4129 free the data after the reference count hits zero.
4131 For now on the packet context and everything allocated into it
4132 (including the raw packet from network) must be freed by calling
4133 the new silc_packet_context_free function. Added also new function
4134 silc_packet_context_alloc that must be used now to allocate the
4135 context. This also means that if a routine is asynchronous from
4136 silc_[client/server]_packet_parse_type the packet context must
4137 be duplicated by calling silc_packet_context_dup. Otherwise it
4138 gets free'd after silc_[client/server]_packet_parse_type returns.
4139 Also, one must remember that if packet is duplicated then its
4140 reference count must be decresed by calling the free function as
4141 many times as it was duplicated.
4143 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4144 from both client and server.
4146 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Made joining to a channel working in router environment.
4150 * Cleaned up JOIN command on server side and create function
4151 silc_server_command_join_channel internal routine to make the
4154 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Changed silc_command_pending list to SilcDList. Also, added
4157 `ident' field to SilcServerCommandPending structure to identify
4158 the reply and to call correct callback.
4160 Added silc_server_command_pending_check function to replace the
4161 corresnponding macro. The silc_command_pending list is not
4164 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4165 to set identifier to previously allocated Command Payload. It
4166 is used to set identifier for command when resending Command
4169 * Added silc_command_payload_encode_payload to encode Command
4170 Payload buffer from SilcCommandPayload structure.
4172 * Added silc_argument_payload_encode_payload to encode Argument
4173 payload buffer from SilcArgumentPayload structure.
4175 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Changed WHOIS command to support router connection on server side.
4178 The whois request is always sent to router unless the server is
4179 standalone server. After server has received the reply from the
4180 router will it send the reply to the client.
4182 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4183 broadcast received broadcast packet. The function is used only
4184 by router. The broadcast packet is always sent to the router's
4187 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4188 render given ID to printable string, for log files for example.
4190 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Made basic router to router connections working. At least they
4193 can now connect to each other but nothing really works the way
4194 they are supposed - yet.
4196 * Added new initiator token to RouterConnection configuration
4197 file in silcd/serverconfig.[ch]. It is used to tell whether we
4198 are the initiator to the remote router or whether we'll expect
4199 the other end to connect.
4201 * Moved registering of listener task to silc_server_init, hence
4202 the server starts listenning as soon as it is run, even if it
4203 does not have connections to other routers. Let's see how well
4206 * Changed default connection retry timeouts for more suitable in
4209 * Removed cipher and such arguments from silc_idlist_add_client
4210 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4211 Added new function silc_idlist_add_data to add the keys and stuff
4214 * Added SilcIDListData structure and added it to SilcClientEntry
4215 and SilcServerEntry as their first field in the structure. This
4216 way we can explicitly cast the ID entries to the SilcIDListData
4217 structure and get common data for the entries. In past, we had
4218 to first check what type of connection it is and then cast it to
4219 correct ID entry type. Now, we can directly cast the opaque
4220 pointer to the SilcIDListData (no matter what ID entry it actually
4221 is) and get the data needed.
4223 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4226 in some circumstances even if threre were timeout tasks, though not
4227 IO tasks, but tasks anyway. Now fixed.
4229 * Defined SilcServerConnection structure to hold connection specific
4230 stuff about directly connected servers and routers. The definition
4231 is currently in silcd/server_internal.h. I thought about having
4232 a bit more important role fro this struct but for now it is used
4233 only when connecting to other server (or router actually).
4235 * Added connecting retry support in server when connecting to
4236 router(s). The retry feature implement exponential backoff
4237 algorithm. Also, added SilcServerParams structure to hold default
4238 parameters for server. For now, it include these retry settings
4239 and are hard coded. After server is moded to be as Silc Server
4240 Library this structure will be more important.
4242 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Changed client librarys channel->clients table to SilcList and
4245 changed code accordingly.
4247 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Changed client's channel table to SilcList and changed code
4250 accordingly. Also changed SilcChannelClientEntry to include back-
4251 pointer to the channel so that client entry can use that structure
4252 as list as well and we have fast cross-reference to the channel.
4253 This change dramatically decreased the complexity of channel
4254 handling with client entry and vice versa (removed one extra
4255 loop when searching for channel entry from many functions).
4257 * Changed server->sim from table to SilcDList and changed code
4260 * NAMES command can now be used from user interface. It will show
4261 the user list on the channel, neatly.
4263 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4264 Code now saves realname of the user if it becomes available.
4266 * Renamed configure.in to configure.in.pre and made ./prepare
4267 script to automatically add correct version string to
4268 configure.in which it creates from configure.in.pre.
4270 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * NAMES command reply now shows users mode with the nickname when
4275 * Moved silc_client_ch[u]mode[_char] functions from
4276 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4277 place sucks, they are utility functions and should be in some
4280 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4282 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4285 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Added TRQ (efficient deque and list library) into lib/trq. This is
4290 a very good list library that is currently used in the SILC. Defined
4291 SilcList API over the library because I didn't like the API very
4292 much. See lib/trq/silclist.h for the API and examples of how to
4293 use the API. Fixed various places in the code to use the new
4294 SilcList API. The SilcList is meant for lists that has a structure
4295 already defined as a list. It is not suitable to add just some
4296 context to the list (in TRQ, the context is the list actually).
4298 So, I defined SilcDList that can be used for the purpose where
4299 predefined list structure does not exit. This can be used as
4300 such list. Now some context just can be added to the SilcDList.
4301 Currently this list is not used in the SILC just yet, though there
4302 are a lot places where this can replace dynamically allocated
4303 tables and I will fix these places, later, to use SilcDList.
4304 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4305 and use TRQ internally).
4307 Also fixed some annoying warning messages that the original TRQ
4308 code generated. Also minor changes to TRQ's Makefile.in.
4310 * Added support for querying by Client ID to both WHOIS and
4311 IDENTIFY commands into server, as required by the protocol.
4313 * Removed method function pointers from SilcBuffer structure. They
4314 weren't used to anything and just increased the context size for
4315 no good reason. This change also made silc_buffer_alloc and
4316 silc_buffer_free functions inline functions.
4318 * Disabled command flooding detection support until it's fixed so
4319 that it accepts commands in but does not execute them more than once
4322 * Added silc_net_localhost(), to return local hostname, into
4323 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4324 that must be initialized before calling silc_client_init.
4326 * Added new function: silc_server_send_notify_on_channels to send
4327 notify messages to all channels client has joined. It is assured
4328 that the message is sent only once per client.
4330 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4331 lib/silcutil/silcutil.[ch] as silc_format function. The new
4332 function is generic and is used by server as well, not only by
4333 the logging routines.
4335 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4336 the provided version string was not acceptable. Added new function:
4337 silc_ske_check_version into lib/silcske/silcske.h. The function
4338 must be implemented by the application (client or server) and it
4339 does not reside in the SKE library. The function checks the version
4340 string remote end sent.
4342 * Added back pointers (to opaque context and to SilcSocketConnection)
4343 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4345 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4346 duplicate packet context structure.
4348 * Changed `notify' client operation to send same arguments as client
4349 receives from server except for ID's. ID's are mapped to correct
4350 ID entry and that is returned. Also, if channel entry is not sent
4351 by server but the notify is for channel the channel entry is sent
4352 to application (otherwise application doesn't know that it is for
4353 channel (library gets it from packet's Destination ID)).
4355 * Added silc_client_remove_from_channels into client library to
4356 remove a client from all channels it has joined to. Used when
4357 received SIGNOFF notify from server. Added also new function
4358 silc_client_replace_from_channels to replace old ID entry with
4359 new ID entry on all channels. Used when received NICK_CHANGE
4362 * Fixed ID Cache list handling in silc_idlist_get_client in
4363 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4364 to get (or query) client by ID.
4366 * Updated TODO list.
4368 * Added connection authentication status message defined by the
4369 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4370 support for these into the code in client and server side.
4372 * Added generic function silc_client_send_command to send any command
4373 with variable argument list. Application should use this function
4374 to send commands if the command functions provided by the library
4375 does not suite for the application's user interface needs.
4377 * Added new `failure' client operation. Application is notified about
4378 received failure packet if client is executing a protocol. In this
4379 case the protocol's execution has failed.
4381 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4382 is required by the protocol.
4384 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4385 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4388 * Added status flag to SilcSKE object to indicate realtime status
4389 of the SKE protocol.
4391 * Application receives now exactly same command reply arguments as
4392 the library receives from server. However, if ID is received the
4393 corresponding ID entry is returned to the application (eg. Client
4394 ID is mapped to correct SilcClientEntry entry and that is returned).
4395 Changed command_reply client operation due to this change.
4397 * Changed all ID's in commands and in command replys as ID Payloads.
4398 Change affected both client and server side codes.
4400 All ID's sent in SILC network (with execption of ID's in SILC
4401 Packet header) are sent in ID Payload to support variable length
4404 * Server now notifies nick changes and notifies all clients on
4405 the channels about the new nickname (about the new Client ID,
4408 * Implemented CMODE command to change channel modes. Supports all
4409 channel modes defined by the protocol specs except ban and invite
4410 lists. (Also, private channel key mode is supported but support for
4411 setting private channel key in client is missing, thus, this mode
4412 has no effect on client side (except that server requires that the
4413 client uses private channel key and normal channel traffic does not
4416 Also, invite mode works per se, but INVITE command does not work
4417 yet correctly, so you can set channel as invite only channel but
4418 inviting clients to the channel does not work (it is yet to be
4419 thought what's the best way to do it).
4421 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4422 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4423 Implemented CUMODE command to change user's mode on the channel.
4424 Supports all modes defined by the protocol specs.
4426 * Added NAMES command reply to return users modes on the channel.
4428 * Removed unnecessary and slow ciphers from lib/silccrypt.
4430 * Set SO_KEEPALIVE option to connection sockets by default.
4432 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4434 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4435 redefined the Notify Payload into protocol specs.
4437 * Added silc_id_payload_parse_id to get ID directly from raw
4440 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4443 accept searching by Client ID as well.
4445 * Added support for LEAVE and SIGNOFF notify types in client library.
4447 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4448 to parse ID Payload from raw data.
4450 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Added flags parameter into silc_ske_assemble_security_properties
4453 function in lib/silcske/silcske.[ch].
4455 * Changed notify client operation to fit better for notify messages
4456 sent by server. The notify payload received from server is now
4457 passed to the application (after parsing it to SilcNotifyPayload).
4458 It is application's responsibility to retrieve the arguments
4459 from the payload and show the message the way it wants. The message
4460 sent by server is implementation specific.
4462 * Changed public keys to comply with the protocol specification.
4463 Old public keys are not supported anymore and are not compatible.
4465 * Removed nickname from Channel Payload as the latest draft removed
4466 it. The client must resolve the nickname from the NAMES command
4467 reply received when it joined the channel.
4469 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4471 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Fixed some errors in protocol specification drafts.
4475 * Created lib/silccore/silcnotify.c to implement Notify Payload
4476 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4477 generic payloads described by protocol specifications. The file
4478 includes implementations for ID Payload and Argument Payload.
4480 * Changed Command Payload implementation to use the new Argument
4481 Payload. Changed command_xxxx_payload to command_payload_xxxx
4482 to comply with SILC coding conventions.
4484 * Added suppport for Argument Payload handling in Notify Payload
4485 implementation as protocol requires it. Added the new support
4486 into server and client lib as well.
4488 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Added support for multiple nicknames on same channel. [n] is
4491 added locally to the nickname if there are more than one same
4492 nicknames on the channel.
4494 * Server now sends all nicknames that matched WHOIS request.
4495 Client also shows the list received from server.
4497 * Added TOPIC command to client side. User can now set and show
4498 current topic on channel.
4500 * Added MOTD command to client and server. Also, server sends the
4501 motd when client connects to the server.
4503 * Changed version strings to comply ISO 8601.
4505 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Fixed protocol error handling in client library. It should now
4508 cope even if the SKE fails for some reason.
4510 * Made new protocol specification drafts for submitting to IETF.
4512 * Implemented TOPIC command to server in silcd/command.c.
4514 * Added two new notify types into lib/silccore/silcnotify.h:
4515 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4516 notify nickname change and topic setting/change on a channel.
4518 * API change of command_reply operation in client library. The
4519 application gets now the status type received from server as well.
4521 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4525 * Cras fixed and optimized the packet handling even further and
4526 it should work now. Minor change to the prototype of function
4527 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4529 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Added new function into lib/silcutil/silcschedule.[ch]:
4532 silc_schedule_with_fd to select() a specified fd. The function
4533 returns after timeout expires or data arrives or goes. The
4534 function is used by packet routines to wait that all data is
4535 received from network.
4537 * Fixed data reading from network in lib/silccore/silcpacket.c.
4538 The code now assures that all data is read from the fd and then
4539 continues packet processing. This was a bug fix since the code
4540 used to drop some data in some circumstances.
4542 * Added new function into lib/silcclient/client.[ch]:
4543 silc_client_start_key_exchange to start key exchange after
4544 connection has been established to server. The code internally
4545 now uses this funtion but its main purpose was to provide it
4546 for applications that perform their own connecting. After
4547 application has created a connection it merely calls this
4548 function to start the key exchange between client and server.
4549 The library takes care of everything else after that.
4551 Updated also lib/silcclient/README to explain the usage of
4554 * Do not send to application information that connection has
4555 been established. Application gets notified it by connect
4558 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Applied cras's patch to add silc_schedule_one function. The
4561 function runs scheduler once and returns.
4563 * Fixed the scheduler after cras messed it up. The timeout
4564 handling works now as it's supposed to work.
4566 * Added into lib/silccore/ silcnotify.h to include notify
4567 message types support. Changed silc_server_send_notify*
4568 functions, in server.[ch], to support those new notify types.
4569 Added the support for the notify types into client library,
4570 as well. Added new notify client operation into ops.h in
4573 * Changed silc_server_packet_send_to_channel to send normal
4574 packets instead of just channel message packets. The function
4575 is now used to send the notify packets to channels. It is not
4576 used to send channel message packets anymore, as server never
4579 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4580 va_arg()s as it seems to require it nowadays. I guess, if SILC
4581 is compiled with older va_arg() the new code should work anyway.
4583 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Splitted core library. Core library (lib/silccore) includes
4586 now only SILC protocol specific core (and common) components.
4587 Created new utility library (lib/silcutil) that includes more
4588 generic purpose stuff. The stuff for util library was taken
4589 from the old core library. This was minor and easy split.
4591 * Created SILC Client Library (lib/silcclient) that includes
4592 implementation of the SILC client without user interface. This
4593 was major move from silc/ directory. The code has been changed
4594 so that it is transparent towards the user interface. The
4595 silc/ directory includes now the same user interface as before
4596 and it uses the new client library. Read lib/silcclient/README.
4597 Basicly, the client library performs everything else related
4598 to SILC except user interface handling. Also, configuration
4599 files are considered to be part of user interface and library
4600 does not handle them.
4602 This change also changed a lot of structures, function naming etc.
4603 Most important change was that SilcClientWindow object was
4604 renamed to SilcClientConnection in the client library. Created
4605 also new file lib/silcclient/ops.h. Also added new files
4606 silc/local_command.[ch] and silc/client_ops.[ch].
4608 All these changes were made to make it easier for user interface
4609 designers to create what ever user interface for the SILC client
4612 It is also expected that the server will be moved to lib
4613 directory as well and SILC Server Library will be created;
4614 sometimes in the future.
4616 * Removed Local commands from lib/silccore/silccommand.h as
4617 they are application specific and new client library does not
4618 handle any of those anymore.
4620 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4621 old client implementation in silc/.
4623 * Added support for callback functions in SILC_LOG_* macros.
4624 Application can now set its own callbacks that will be called
4625 instead of using the default functions that will always print
4626 the debug messages to stderr (or stdout). Also, debugging can
4627 now be disabled by setting silc_debug to FALSE and re-enabled by
4628 setting it to TRUE. Note, that logging will still work even
4629 if debugging is disabled.
4631 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4632 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4633 silc_log_reset_debug_callbacks.
4635 * To enable debugging in silc client one must give now -d
4636 option on command line.
4638 * Changed silc_schedule_init to automatically allocate task queues
4639 if they are not allocated before calling it.
4641 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added GMP 3.1 into math library.
4645 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4648 a channel in SILC network. The packet is used by servers and
4649 routers to notify other routers that user has left a channel.
4650 This little feature was missing until now. Added the feature
4651 to protocol specification as well.
4653 Added functions: silc_server_send_remove_channel_user and
4654 silc_server_remove_channel_user into server.[ch].
4656 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4657 lib/silccore/silcpacket.h. However, they are not implemented
4660 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Fixed joining to a channel and sending channel messages
4663 between server and router. The channel message sending should
4664 now work inside a cell.
4666 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Fixed the private message sending between server and router.
4669 The private message sending should now work inside a cell.
4671 * Added silc_server_replace_id into server.[ch] to replace
4672 existing ID in the SILC network.
4674 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4675 and silc_idlist_replace_server_id into idlist.[ch] in server.
4677 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Fixed the server to server connections. Server can again now
4680 connect to router. Router to router connections probably does
4683 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Added dynamic protocol registering support. Now protocols can
4686 registered and unregistered on the fly. Patch by cras.
4688 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Added lib/contrib directory to hold routines that some platforms
4691 don't have but are needed by SILC.
4693 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4694 into lin/contrib to provide getopt() and getopt_long() for
4695 those who don't have it.
4697 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Added AWAY command to client. When away message is set and
4700 client receives a private message packet the client automatically
4701 replies to the sender with the away message.
4703 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4704 bug seemed to be the cause of recent problems when compiling
4707 * Added version detection support to SKE protocol specification
4708 and added the new changes to the SKE implementation as well.
4709 There were other minor changes in the SKE protocol as well.
4711 Many changes in lib/silcske/silcske.[ch] and in
4712 lib/silcske/payload.[ch].
4714 * Added ^U functionality, clear input line. Patch from cras.
4716 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Mainly small bugfixes on core library. Fixed some debugging
4719 logging and buffer overflow in silclog.c.
4721 * Updated config.sub and config.guess on the distribution tree.
4723 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Added command lagging support in server. Client may execute
4726 commands now only once in two seconds.
4728 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Optimized packet reception. MAC computation and checking is now
4731 also more optimized. A lot previously duplicated code is now
4732 used as generic by both client and server.
4734 * Fixed key pair generation in clientutil.c
4736 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added into lib/silccore/silcbufutil.[ch] new function;
4739 silc_buffer_realloc.
4741 * Moved generic packet sending/encryption functions to
4742 lib/silccore/silcpacket.[ch] from client and server. Some
4743 rewriting of the functions.
4745 * Moved all generic packet reception/decryption functions to
4746 lib/silccore/silcpacket.[ch] from client and server. The
4747 packet processing is now much cleaner in both client and server.
4748 These were major changes in both client and server.
4750 * Created many common functions in server to do packet sending.
4751 Previously code were duplicated a lot, this has been removed
4754 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Rewrote major parts of the ID cache system. Don't know
4757 whether it is better now or not but at least the API is more
4760 * Major rewrite on ID cache stuff on client because of the ID
4761 cache API changes. Added idlist.c to client.
4763 * Also major rewrite on ID cache stuff on server as well.
4764 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4765 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4766 in hand, instead they are all put into the ID cache system now.
4767 All server_idlist_* routines uses ID cache now instead of
4768 traversing its own lists (those lists does not exist anymore).
4769 SilcIDList though still exists. Also, SilcXXXEntry's are
4772 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Finally made the SKE implementation compliant to the protocol
4775 specification. All mp integers are now binary encoded as
4776 opposed being HEX encoded.
4778 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4781 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4782 functions: silc_[encode/decode]_pem. Also added function
4783 silc_encode_pem_file to PEM encode with newlines ('\n') for
4786 * SILC public keys are now encoded either PEM or binary. Same
4787 option is for private keys as well. By default private keys
4788 are binary encoded and public keys PEM encoded. Silly HEX
4789 encoding were removed.
4791 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4792 function to create fingerprints.
4794 * Fixed a bug in SHA1; does not change the original data anymore.
4796 * Partly implemented INFO command on client and server side.
4797 Fixed CLEAR command. Changes to SERVER command; show current
4798 server(s) when giving command without arguments. Added
4799 VERSION command to client.
4801 * Added check to server that unregistered connections cannot
4802 execute commands (unless it is specificly allowed).
4804 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Fixed screen refresh.
4808 * Fixed channel joining bug from client. On some circumstances
4809 client tried to join to a channel it had already joined.
4811 * Added public key verification process into client's protocol.c.
4812 The client now verifies the public key from user and saves
4813 it into ~./silc/serverkeys/ directory.
4815 Added into: clientutil.[ch]: silc_client_verify_server_key.
4817 * Changed SKE protocol's silc_ske_initiator_finish function
4818 to accept callback function that verifies the received public
4819 key. Removed old silc_ske_verify_public_key function.
4821 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4824 silc_pkcs_private_key[_data]_set.
4826 * Made the password and public authentication more cleaner in
4827 server's protocol.c.
4829 * Removed historic and obsolete protocol `channel_auth' from
4830 both client and server.
4832 * Removed wrong way of sending command status messages from
4833 server to client in server's command.c. The old way violated
4834 protocol specification.
4836 Changes to silccore/silccommand.[ch]: removed
4837 silc_command_encode_status_payload -> not needed anymore,
4838 changed silc_command_encode_payload_va to accept extra
4839 argument on variable argument list. The argument type must
4840 now be provided to the function. Also, added new function:
4841 silc_command_encode_reply_payload_va which is same as
4842 normal command_encode_payload_va except command status type
4843 is provided as extra argument.
4845 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Added ~./silc directory handling. The directory includes the
4848 public and private keys for the client.
4850 Added silc_client_check_silc_dir, silc_client_create_identifier
4851 and silc_client_load_keys.
4853 * Implemented SILC protocol compliant public key. Added public
4854 and private key saving to and loading from files.
4856 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4857 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4858 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4859 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4860 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4862 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4863 silc_pkcs_load_[public/private]_key.
4865 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Added silc_server_get_route (route.[ch]) to get connection
4868 data for the fastest route for given ID.
4870 * Implemented INVITE command on client and server. The command
4871 were re-defined in the SILC Protocol Specification and the
4872 implementation now complies with the specification.
4874 * Implemented PING command on client and server.
4876 * Implemented NAMES command on client and server. The server side
4877 supports currently only normal server not router server yet.
4878 Some changes to NAMES definition in SILC protocol specification.
4880 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Implemented LEAVE command on client and server.
4884 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4885 again. This change was made to the protocol as well. Server
4886 should not violate the protocol specification anymore.
4888 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4891 was tested. SOCKS4 was not but should work anyway.
