1 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the getkey command handling in the server. Send just
4 empty OK reply to the sender if the key could not be fetched
5 (but everything else was ok, like the key just was not available).
6 Changed the public key parameter to optional in the protocol
7 specs so that empty OK reply can be sent. Affected file
10 Added a message to Irssi SILC client to tell to user if the
11 server did not return a public key.
13 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
15 * Fixed a channel key regeneration bug. It registered new
16 timeout tasks exponentially until all system resources were
17 used. Affected file silcd/server.c.
19 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Added the SILC Document generator to the scripts/silcdoc.
22 It can be used to generate the Toolkit Reference Manual out
23 of the source tree. Internally it will also use the RoboDoc
24 generator now imported in util/robodoc.
26 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
28 * Added couple of return's in rekey protocol if error orccurred
29 during the protocol. The execution must be terminated.
30 Affected file silcd/protocol.c. Also, terminate the protocol
33 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
35 * The client's Client ID was created initally from the wrong
36 nickname (it could have been in format nick@host) in the
37 silc_server_new_client. Affected file silcd/packet_receive.c
39 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
41 * Added some SILC_LOG_ERROR's to various error conditions
42 if client could not be added to ID cache. Affected files
43 silcd/packet_receive.c and silcd/server.c.
45 * When client's sock->user_data is freed, NULL also the
46 client->router and client->connection pointers. Added check
47 for these pointers being NULL to various places around the
48 code. Affected file silcd/server.c.
50 * Added client->data.registered == TRUE checks to various
51 places around the code to assure that unregistered client's
52 are not handled when it is not allowed. Affected file
55 * Added `bool registered' fields to all
56 silc_idlist_[server|client]_get_* routines to indicate whether
57 the fetched client needs to be registered or not. Affected
58 file silcd/idlist.[ch].
60 * Add your own entry as registered to the ID cache in the
61 server. Affected file server.c.
63 * Fixed a bug in silc_server_new_server. The SilcServer was
64 set as the new server's context instead of SilcServerEntry.
65 This naturally caused some weird bugs.
67 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
69 * Do not delete the channel rekey task when adding it
70 for in silc_server_create_channel_key.
72 * Changed the silc_server_create_channel_key to return
73 TRUE or FALSE to indicate the success of the channel key
76 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
78 * Fixed MSVC++ project files and added missing files to
79 Makefiles under win32/.
81 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
83 * Do not add TCP_NODELAY flag if the operating system
84 does not have it defined. Affected files are
85 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
87 * Fixed buffer overflow from Irssi SILC Client. Affected
88 file irssi/src/fe-common/core/themes.c.
90 * Fixed double free in client library in the file
91 lib/silcclient/client.c when disconnecting from server.
93 * Applied double free patch from cras to Irssi SILC client.
94 Affected files irssi/src/core/[modules/expandos].c
96 * Fixed the disconnection handling to Irssi SILC Client.
97 The application must call silc_client_close_connection
98 in ops->connect client operation in case of failure of
99 the connection. Affected file is
100 irssi/src/silc/core/client_ops.c.
102 * Do not set sock->protocol to NULL in the function
103 silc_client_close_connection after executing the protocol's
104 final callback since the sock might not be valid anymore.
105 Affected file lib/silcclient/client.c.
107 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
109 * Do not enable SILC_THREADS if the linking with libpthread
110 did not happen. Affected file configure.in.pre.
112 * Added notion to protocol specification that server must
113 verify the sent authentication payload with CMODE when
114 setting the channel founder key. Implemented it to the
115 server. Affected file silcd/command.c.
117 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Added _EXTRA_DIST SILC distribution variable to the
120 distributions file. It is used to conditionally add extra
121 files or directories to the specific distribution. Affected
122 files ./prepare, Makefile.am.pre and distributions.
124 Removed the `_' from the start of the distribution names.
127 * Added README.WIN32 for instructions to compile the Toolkit
130 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
132 * Fixed a double free in disconnection in the server. Affected
133 file is silcd/server.c.
135 * Fixed the lib/silcske/groups.c to work now also with GMP
136 MP library. The string conversion did not work when using
137 specific base and the base is indicated in the string as well.
139 * Created win32/ directory which now includes MSVC++ specific
140 stuff so that toolkit (DLLs) may be compiled with MSVC++.
141 It will appear only in the toolkit distribution
143 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
145 * Changed the key material distribution function in case when
146 the hash output is too short. The data is now concatenated
147 a bit differently than it used to. Made the change to the
148 SKE protocol specification.
150 * Added better GMP detection to configure.in.pre. A patch
153 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
155 * Fixed a minor bug in SKE that might cause some problem on
156 some platforms. Affected file lib/silcske/silcske.c.
158 * Added the cookie checking for initiator in the SKE. It checks
159 that the responder returns the sent cookie unmodified. The
160 affected file is lib/silcske/silcske.c. Added new SKE
161 error type INVALID_COOKIE that can be sent during the
162 negotiation. Fixed some memory leaks as well.
164 * Added the "invalid cookie" error message to Irssi SILC client's
167 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
169 * Added `task_max' field to the SilcClientParams to indicate
170 the maximum tasks the scheduler can handle. If set to zero,
171 default values are used. Affected file lib/silcclient/silcapi.h.
173 * Fixed memory leaks in silc_client_close_connection. Affected
174 file lib/silcclient/client.c.
176 * Added silc_client_del_client_entry to client library to free
177 all memory of given client entry. Affected file is
178 lib/silcclient/idlist.[ch].
180 * Added new functions silc_client_del_channel and
181 silc_client_del_server to delete channel and server entries.
182 Affected file lib/silcclient/[silcapi.h/idlist.c].
184 * Removed silc_client_del_client_by_id from silcapi.h.
186 * Fixed the INFO command to return the server's own info
187 correctly when querying by Server ID. Affected file is
190 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
192 * Removed the non-blocking settings in WIN32 code in the
193 silc_sock_[read/write] and added SleepEx instead. Affected
194 file lib/silcutil/win32/silcwin32sockconn.c. The availability
195 of input data is now checked with FIONREAD and ioctlsocket.
197 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
199 * Call silc_schedule_task_del_by_context in the
200 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
201 Affected file lib/silccore/silcprotocol.c.
203 * Call silc_protocol_cancel for active protocols in the
204 silc_server_close_connection if the funtion
205 silc_server_free_sock_user_data has not been called.
206 Affected file silcd/server.c.
208 * Generic tasks cannot be deleted using the del_by_fd
209 task deleting function since generic tasks does not match
210 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
212 * Added a notion to SILCOPER help file that the SILCOPER works
213 only on router server, not on normal server.
215 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
217 * Added for WIN32 support for the new scheduler as well.
218 Affected file lib/silcutil/win32/silcwin32schedule.c.
220 * Fixed the SHA1 implementation to work on various platforms.
222 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
224 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
225 API. It is part of the scheduler now. Everything else is
226 as previously but some functions has changed their names.
227 Checkout the lib/silcutil/silcschedule.h for the interface.
228 Updated all applications to use the new interface. Affected
229 files are lib/silcutil/silcschedule.[ch].
231 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
233 * Found a bug in the SKE implementation. The HASH value,
234 specified by the protocol, was not computed correctly. The
235 public key of the responder was not added to the computation
236 even though it is mandatory. Affected file lib/silcske/silcske.c.
237 This unfortunately causes incompatibilities with older
240 * Added WIN32 specific network init and uninit functions:
241 silc_net_win32_init and silc_net_win32_uninit to init and uninit
242 the Winsock2. Affected file lib/silcutil/silcnet.h and
243 lib/silcutil/win32/silcwin32net.c.
245 * Set the socket always to nonblocking mode on WIN32 after
246 reading data or writing data. Affected file is
247 lib/silcutil/win32/silcwin32sockconn.c.
249 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
251 * Fixed various compilation problems under WIN32. Affected
252 files lib/silcutil/win32/silcwin32thread.c and
253 lib/silcutil/win32/silcwin32schedule.c.
255 * Removed all _internal.h #includes from public header
256 files. Internal headers must never be included from
259 Removed also the lib/silcske/payload_internal.h file.
261 * All include files that may be needed (public and some others
262 included by the public headers) by application developers are
263 now copied to the ./includes directory. It does not copy any
264 internal headers. Affected file Makefile.defines.pre and all
265 Makefile.am's under lib/ and subdirs.
267 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Do not change the ~/.silc directory's permissions automatically.
270 Affected file irssi/src/silc/core/clientutil.c.
272 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
274 * Do not cancel the protocol in silc_server_close_connection
275 it might cause recursion. Now cancelled in the function
276 silc_server_free_sock_user_data. Affected file silcd/server.c.
278 * Fixed the silc_server_remove_clients_by_server to regenerate
279 the channel keys correctly finally. Added also new function
280 silc_server_remove_clients_channels to actually do it.
281 Affected file silcd/server.c.
283 * Fixed the silc_server_new_channel to not crash by giving
284 wrong router to the new channel. Affected file is
285 silcd/packet_receive.c.
287 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
289 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
290 which is given as argument to the silc_client_alloc now.
291 It can be used to configure the client and set various parameters
292 that affect the function of the client.
294 * The USERS command in server did not check whether the channel
295 is private or secret. Affected file silcd/command.c.
297 * Added new argument to the USERS command in protocol specification.
298 The USERS command now can take the channel name as argument
299 as well. Added support for this in client and server and
300 updated the protocol specs.
302 * Completed the GETKEY command in client. It can be now used
303 to fetch also servers public key not only some clients.
304 Affected files lib/silcclient/command[_reply].c.
306 * Added silc_client_get_server to return server entry by the
307 server name. Affected files lib/silcclient/silcapi.h and
310 * Redefined the IDENTIFY command in protocol specification to be
311 more generic. It now can be used to query information about
312 any entity in the SILC Network, including clients, servers and
313 channels. The query may be based either the entity's name
314 or the ID. Added support for this in both client and server.
316 Affected files silcd/command.c and lib/silcclient/command.c
319 * Optimized the WHOIS and WHOWAS commands in the server. Removed
320 the _from_client and _from_server functions. Affected file
323 * Added silc_client_get_channel_by_id_resolve to the file
324 lib/silcclient/silcapi.h to resolve channel information by
325 its ID. Added also silc_client_get_channel_by_id that
326 does not resolve it from the server.
328 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Added SilcServerEntry context into the client library
331 to represent one server. The INFO command now allocates
332 these to save the resolved server info. For now on the
333 client library will also keep information about servers,
334 connected and resolved with INFO.
336 The INFO command now allocates the SilcServerEntry context
337 and saves the server info there. The COMMAND_REPLY in
338 the INFO now returns the parameters to application in
339 same order as defined in the protocol specification.
341 The entries are cached in the client->server_cache.
343 * The INFO command is now issued after received the Client ID
344 from the server. Affected file lib/silcclient/client.c.
346 * The CMODE_CHANGE notify may now return also an SilcServerEntry
347 to the application as the mode changer might be server.
348 It is guaranteed that NULL is not returned anymore to the
349 application. Affected file lib/silcclient/client_notify.c.
351 The ID Type is now also passed to the application so that
352 it can check whether the returned entry is SilcClientEntry
355 Added new function silc_client_get_server_by_id to return
356 the server entry by ID. Affected files are the
357 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
359 * Do not create the channel in the Irssi SILC Client when issuing
360 the JOIN command but when received the sucessful JOIN command
361 reply. Otherwise the channel might get created even though we
362 could not join it. The Affected file is
363 irssi/src/silc/core/[silc-channels.c/client_ops.c].
365 * Fixed a channel joining bug in router. The router must also
366 check the channel modes, invite and ban lists etc. when serving
367 the JOIN command sent by normal server. Affected file is
368 silcd/command.c. The router now resolves the client's
369 information from the server who sent the JOIN command if it
370 does not know it, and processes the JOIN command only after
373 * Changed the SilcCommandCb to take new argument; void *context2.
374 Affected file lib/silccore/silccommand.h
376 The second argument in the command callbacks in the server now
377 includes the SilcServerCommandReplyContext if the command was
378 called as pending command callback from the command reply.
379 Otherwise it is NULL. When called as pending the status of the
380 command reply will be checked and if it was erronous the
381 error will be sent to the original sender of the command.
382 This way the client always receives the error messages even
383 though the server was actually the one who received the error
384 when it resent the command to router, for example. Affected
385 files silcd/command[_reply].[ch].
387 * Fixed sending WHOWAS command's error message to client if
388 the requested client could not be found. It was missing.
391 * Changed the CMODE and CUMODE commands reply arguments in the
392 protocol specification. The Channel ID is now sent in both
393 of the commands to identify the channel. Implemented this
394 new feature to the client and server. Affected files
395 lib/silcclient/command_reply.c and silcd/command.c.
397 * Made better checks for invite and ban lists in the JOIN
398 command in server. Affected file silcd/command.c.
400 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
402 * The server now performs the incoming host IP/DNS lookup
403 using the silc_socket_host_lookup and thus does not block
404 the server anymore. Affected file silcd/server.c.
406 * Completed the multi-thread support for SILC Scheduler in
407 the lib/silcutil/silcschedule.c.
409 * Fixed the configure.in.pre to detect the pthread correctly
412 * Fixed a deadlock in silc_task_queue_wakeup in the file
413 lib/silcutil/silctask.c.
415 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
417 * Added new function silc_schedule_wakeup that is used in
418 multi-threaded environment to wakeup the main thread's
419 schduler. It needs to be used when a thread adds a new task
420 or removes a task from task queues. After waking up, the
421 scheduler will detect the task queue changes. If threads
422 support is not compiled in this function has no effect.
423 Implemented the wakeup mechanism to both Unix and WIN32
424 systems. Affected files are lib/silcutil/silcschedule.[ch],
425 lib/silcutil/unix/silcunixschedule.c and the
426 lib/silcutil/win32/silcwin32schedule.c.
428 * Added new function silc_task_queue_wakeup to wakeup the
429 scheduler by the specified task queue. Affected file
430 lib/silcutil/silctask.[ch].
432 * The silc_socket_host_lookup_start now wakes up the scheduler
433 after adding the timeout task. Affected file is
434 lib/silcutil/silcsockconn.c.
436 * The silc_socket_host_lookup is synchronous now if the threads
437 support is not compiled in. However, the callback is still
438 called asyncronously through the scheduler, anyway. Affected
439 file lib/silcutil/silcsockconn.c.
441 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Added new function silc_socket_host_lookup to perform
444 asynchronous IP and FQDN lookups for the socket connection.
445 Affected files lib/silcutil/silcsockconn.[ch].
447 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
449 * Added SILC_MUTEX_DEFINE to define the mutex on environments
450 that may or may not compile the mutex support in.
452 Changed the silc_mutex_alloc interface. It allocates the
453 mutex now to the sent pointer and returns TRUE or FALSE.
455 Affected file lib/silcutil/silcmutex.h.
457 * Wrote the SILC Task Queue interface to support multi-threads.
458 Affected file lib/silcutil/silctask.[ch].
460 * Wrote the SILC Scheduler to support multi-threads. Affected
461 file lib/silcutil/silcschedule.c.
463 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Implemented the SILC Mutex API and SILC Thread API for WIN32
466 in lib/silcutil/win32/.
468 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
470 * Defined SILC Mutex API and SILC Thread API and implemented
471 them for Unix. Affected files are
472 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
473 lib/silcutil/unix/silcunixmutex.c and
474 lib/silcutil/unix/silcunixthread.c.
476 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
478 * Fixed the silc_server_remove_clients_by_server's channel
479 key re-generation. The hash table handling was incorrect
480 and would not work with many channels. Affected file is
483 * Fixed some memory leaks around the server code.
485 * Rewrote the silc_server_get_users_on_channel to support IPv6
486 based Client ID's. Affected file silcd/server.c.
488 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
489 specification. However, a separate document must be written
490 to define the detailed signing procedure and the payload
491 associated with the flag. Defined the flag to the
492 lib/silccore/silcchannel.h as well.
494 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Changed the dynamic tables to static size tables in the
497 lib/silccrypt/silchmac.c.
499 * Removed GCC dependencies from the code. A patch by cras.
501 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
503 * Do not show the error "Error receiving packet bla bla"
504 in server if it really was not an error (-2 means that reading
505 is pending). Affected file silcd/server.c.
507 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
509 * Fixed a possible crash in silc_server_remove_clients_by_server
510 in silcd/server.c. Fixed there also some memory leaks.
512 * Fixed the silc_idlist_replace_client_id. It could replace
513 wrong key in the hash table. Affected file silcd/idlist.c.
515 * Do not check whether there are global users on the channel
516 if the channel->global_users is FALSE. Affected functions
517 silc_server_remove_from_one_channel and
518 silc_server_remove_from_channels in silcd/server.c. Also,
519 do not check if the removed client is local as we can be
520 sure that global client was not removed from the channel
521 and checking for global users is not needed.
523 * The silc_server_remove_clients_by_server now re-generates
524 the channel keys correctly for those channels that had
525 clients removed from them. Affected file silcd/server.c.
527 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Found the reason of random crashes in the server. We weren't
530 ignoring the SIGPIPE signal (which can be sent in write())
531 and it crashed the server. Affected file silcd/silcd.c.
533 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
535 * Assure that sock->user_data is not NULL in the function
536 silc_server_packet_send in silcd/packet_send.c.
538 * Disconnect the remote connection if it could not be added
539 to any ID lists in the server. The affected file is
542 * Check in silc_server_packet_send[_real/dest] that the
543 socket is not disconnecting and ignore the data if it is.
544 Affected file silcd/packet_send.c.
546 * Define inline to __inline on native WIN32 compilation.
547 Affected file includes/silcwin32.h.
549 * Added some explicit type casts for inline code since MSVC
550 require them. Affected files lib/silcutil/silcbuffer.h,
551 lib/trq/silcdlist.h and lib/trq/silclist.h.
553 * Print warning in log files from now on if the packet
554 decryption fails. Affected file silcd/server.c.
556 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
558 * Changed the `say' client operation's interface to accept
559 new `type' argument to indicate the type of the message sent
560 by the library. The application may filter the library's
561 messages according the type. The affected file is the
562 lib/silcclient/silcapi.h.
564 * Added two new functions to lib/silcclient/silcapi.h:
565 silc_client_del_client and silc_client_del_client_by_id.
566 Affected file lib/silcclient/idlist.c.
568 * Moved the clientincludes.h from includes/ to silc/ and
569 serverincludes.h from includes/ to silcd/.
571 * The modes for the CMODE and CUMODE are now passed as
572 uint32 for application with COMMAND_REPLY. The affected
573 file is lib/silcclient/command_reply.c.
575 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
577 * /WHOIS without arguments shows client's own information.
578 Affected file lib/silcclient/command.c.
580 * Changed PING to not accept any arguments. The specs
581 says that client can ping only the connected server so
582 requiring an argument is not needed. Affected file is
583 lib/silcclient/command.c.
585 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
587 * Fixed a fatal bug in private message sending and reception
588 encryption and decryption when using private message keys.
589 The implementation was incorrect and did not follow the
590 specification. It causd that some of the message were
591 lost since it did not use the sending and receiving keys
592 as the protocol suggests. This has been fixed and will cause
593 incompatibilities with older clients when sending private
594 message encrypted with private message keys. Affected files
595 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
596 and various other in Irssi SILC Client.
598 Added `responder' boolean argument to the functions
599 silc_client_add_private_message_key[_ske] to indicate when
600 the key is added as responder or initiator of the key
603 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
605 * Removed the silc_ske_check_version function and created
606 a SilcSKECheckVersion callback. Added also a function
607 silc_ske_set_callbacks that is now used to set all SKE
608 callbacks. The callback functions are not given to
609 the SKE functions anymore, but this function is used to
612 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
614 * Added `silc_version' argument to the silc_client_alloc
615 to define the version of the application for the library.
616 The library will use the version string to compare it
617 against the remote host's (usually a server) version
618 string. Affected file lib/silcclient/silcapi.h
620 * Added the KE protocol context to Key Agreement context
621 in client library so that we can abort the SKE if it
622 is in process when we get timeout. Affected file is
623 lib/silcclient/client_keyagr.c.
625 * Do not resolve the client ID forever if it returns in the
626 first time that such client does not exist. This was done
627 for example with private message. Affected file is
628 lib/silcclient/client_prvmsg.c.
630 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Do not add regex.h for WIN32. The affected file
633 includes/silcincludes.h.
635 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
636 not work yet 100%. It generates the DLL's automatically
637 when compiling with --with-win32 under cygwin.
639 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
641 * lib/contrib/regex.c is not compiled on WIN32.
643 * Added silc_net_get_socket_opt function to the
644 lib/silcutil/silcnet.h.
646 * Added includes/silcwin32.h for WIN32 specific includes
649 * Do not use ptime structure or any of the posix process
650 functions on WIN32 in lib/silccrypt/silrng.c.
652 * Added silc_gettimeofday to provide generic function
653 for struct timeval on all platforms. Added the function
654 to lib/silcutil/silcutil.h.
656 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
658 * Moved the lib/silccore/silcsockconn.[ch] to the utility
659 library as they clearly belong there. As a plus side we
660 can make the actual socket connection routines platform
663 Added also new generic function silc_socket_read and
664 silc_socket_write (that used to be silc_packet_[read/write].
665 The implementation of these are platform specific.
667 * Added WIN32 specific routines of silc_socket_[read/write]
668 to lib/silcutil/win32/silcwin32sockconn.c.
670 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
672 * Added preliminary support for native WIN32 compilation under
673 cygwin (using the -mno-cygwin option for GCC) to the
674 ./configure.in.pre. The --with-win32 now prepares the
675 compilation for native WIN32.
677 * Rewrote the SILC Scheduler interface in the file
678 lib/silcutil/silcschedule.h. The scheduler is now context
679 based and does not have anymore any global static scheduler.
680 Moved the Unix scheduler to the lib/silcutil/unix/ directory
681 and created lib/silcutil/win32 directory for WIN32 based
684 * Added Unix specific network routines to the
685 lib/silcutil/unix/silcunixnet.c and the old
686 lib/silcutil/silcnet.c includes now only generic routines.
688 Added WIN32 specific network routines to the
689 lib/silcutil/win32/silcwin32net.c.
691 * Added Unix specific utility functions from the
692 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
694 * Added WIN32 SILC Scheduler to the file
695 lib/silcutil/win32/silcwin32schedule.c. The code is of course
698 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Do not handle JOIN notify in the server if the target client
701 is not registered (idata->registered == FALSE). The affected
702 file is silcd/packet_receive.c.
704 * Update the nickrec->founder in event_cumode in the Irssi SILC
705 client. Affected file irssi/src/silc/core/silc-channels.c.
707 * Fixed the CUMODE_CHANGE notify handling in the server when
708 server and router are announcing their clients on channels.
709 Now the mode changes are saved and notified correctly. The
710 affected file is /silcd/packet_receive.c.
712 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
713 They really did not replace the cache entry in the ID Cache.
714 Now they do that. Affected file silcd/idlist.c.
716 * Fixed the KICK notify handling in the Irssi SILC client to
717 update the channel records so that the kicked client does not
718 appear to be on the channel. The affected file is
719 irssi/src/silc/core/silc-channels.c.
721 * Always update the conn->current_channel when executing command
722 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
724 * Fixed the KILL notify handling in Irssi SILC client to remove
725 the killed client on all channels.
727 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Fixed the silc_parse_command_line to remove extra spaces
730 from the start and end of the arguments. Affected file is
731 lib/silcutil/silcutil.c.
733 * Cancel and free any active protocol in the function
734 silc_server_close_connection. Affected file silcd/server.c.
736 * Cancel and free any active protocol in the function
737 silc_client_close_connction. Affected file is
738 lib/silcclient/client.c.
740 * Do not execute the KILL command for clients that are in
741 history (ie. they are not in the network). Affected file is
744 * Fixed KILL notify handling, client does not crash anymore.
745 Affected file irssi/src/silc/core/silc-channels.c.
747 * Reduced the default packet buffer size from 2048 to 1024 in
748 lib/silccore/silcpacket.c.
750 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
751 counter to the SKE context that is incresed when the SKE library
752 performs async operation outside the library. If the outside
753 process frees the SKE context and FREED status will be set
754 and the library will detect after the sync operation that the
755 libary is freed. The affected files are
756 lib/silcske/silcske[_status].[ch].
758 * Resolve the client entry information in the function
759 silc_client_channel_message to assure that NULL pointer is not
760 passed as client entry to the application. */
762 * Fixed the task timeout calculation to assure that there is
763 never negative timeouts. The affected file is
764 lib/silcutil/silcschedule.c.
766 * Fixed the channel user mode notification sending in server.
767 It was sent point-to-point to the router (or to server by router)
768 but it needs to be destined to a channel. The routines now
769 supports sending the channel user mode notifys to the channels
770 when announcing clients and channels. Affected files are
771 silcd/server.c and silcd/packet_receive.c.
773 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
774 It did not actually replace the old channel entry in the cache.
775 Affected file lib/silcclient/client_notify.c.
777 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Fixed a possible crash in silc_packet_send_prepare. It now
780 assures always that there is enough space in the buffer and
781 at the tail area of the buffer (for MAC).
783 Fixed the inbound buffer reallocation in silc_packet_read.
784 It was old code and did not handle the reallocation correctly.
787 The affected file is lib/silccore/silcpacket.c.
789 * Fixed buffer overflow in silc_parse_nickname in the file
790 lib/silcutil/silcutil.c.
792 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
794 * make install generates new server keys only if there is not
797 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
800 Added check that if the NOREPLY is set then we will not send
801 the away message. This avoids infinite loop of away messages
802 if both clients are away. The affected file is
803 lib/silcclient/client_prvmsg.c.
805 * Fixed client crash if /NICK was given without arguments.
806 Affected file lib/silcclient/command.c.
808 * Server does not send the invite list in INVITE command back
809 to the client if the list was not altered. Added this notion
810 to the protocol spec as well. Affected file silcd/command.c.
812 Fixed possible crash in INVITE command by checking the
813 value of silc_server_get_client_route command.
815 * Fixed the INVITE notify type handling. The arguments are now
816 taken in correct order and client does not crash. The affected
817 file is irssi/src/silc/core/silc-channels.c.
819 Removed the "Inviting xxx to channel" message from the
820 client library away and let the application handle it.
821 Affected file lib/silcclient/command.c. Added that message
822 to Irssi SILC client's message formats.
824 * Fixed CMODE command crash in client. It now checks the
825 amount of arguments correctly and does not crash. The affected
826 file is lib/silcclient/command.c.
828 * Do not create new channel automatically in silc_channels_join
829 but check whether the channel by that name already exists.
830 Affected file irssi/silc/core/silc-channels.c.
832 * Do not send the SERVER_SIGNOFF to router if the disconnected
833 entity was the router. Affected file silcd/server.c.
835 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
836 SILC client as it was missing from there.
838 Added the handling of the KICK notify to the Irssi SILC client
839 as it was missing. Added "you have been kicked" message to
840 Irssi SILC client's message modules formats.
842 Added the handing of the KILL notify to the Irssi SILC client
843 as it was missing. Added the kill message module formats
846 The affected file is irssi/src/silc/core/silc-channels.c.
848 * The router did not save the channel mode the server announced.
849 Affected file silcd/packet_receive.c.
851 * Fixed a possible crash in INFO command in server. If the
852 server did not provide the server info it crashed. Affected
853 file silcd/command.c.
855 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Fixed the GETKEY command in the server to check also the
858 global list. Otherwise the GETKEY would not work correctly
859 in normal SILC server. Affected file silcd/command.c.
861 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
863 * Fixed GETKEY crash, it crashed if the command did not succseed.
865 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
868 is now real and not just an macro interface to GMP.
870 Removed the entire GMP from the source tree and imported new
871 NSS MPI library instead. Reason for removing GMP is that it is
872 extremely large and compiles extremely slow. The NSS MPI
873 is only a few files and compiles in less than 10 seconds.
874 The speed is also about the same as GMP. The MPI is imported
877 If the system has GMP installed we will still use the GMP.
878 If it is not then the NSS MPI will be compiled.
880 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Merged a long nickname (127 characters long) crash bugfix from
883 Irssi CVS tree. Affected file irssi/src/core/misc.c.
885 * Merged a freed memory reference bugfix from Irssi CVS tree.
886 Affected file irssi/src/core/commands.c.
888 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Added the server's public key sving and verification to the
891 server when performing the SKE. This was missing and the
892 remote server's (or router's) public key was accepted without
893 checking whether we have it previously or trust it at all.
894 Affected file silcd/protocol.c.
896 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Check in the silc_server_timeout_remote if protocol is active
899 and make sure that the protocol's final callback is called so
900 that all memory if freed. Affected file silcd/server.c.
902 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * silc_server_whois_send_reply crashed the server if the nickname
905 was 127 characters long. Affected file silcd/command.c.
907 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Added sanity check to the silc_server_new_client. If the hostname
910 is provided inside username then check that the provided hostname
911 really is the same as the resolved one. If the hostname was not
912 resolved then check it from the public key. Affected file is
913 silcd/packet_receive.c.
915 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
916 if the server disconnected us and the connection is not valid
917 anymore. Affected file irssi/src/silc/core/silc-channels.c.
919 * Moved the silc_client_[chmode|chumode|chumode_char] away from
920 the library to the lib/silcutil/silcutil.[ch].
922 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Close log file after open. Affected file
925 lib/silcutil/silclog.c.
927 * Check whether sock == NULL in silc_client_send_packet and return
928 if it is. Affected file lib/silcclient/silcclient.c.
930 * Check rec->entry == NULL in the Irssi SILC Client before
931 sending the channel message. Affecte file is
932 irssi/src/silc/core/silc-servers.c.
934 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * Merged a splitted window bugfix from Irssi CVS tree. The
937 affected file is irssi/src/fe-text/textbuffer-view.c.
939 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
940 It did not print nickname.
942 * Improved the distributions system a bit.
944 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
947 irssi/src/fe-text/gui-window.c.
949 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
950 to in-active server. The affected file is
951 irssi/src/silc/core/client_ops.c.
953 * Resolve the client in USERS command reply if the entry does
954 not have username resolved. The affected file is
955 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
956 command to WHOIS command to really resolve stuff. The USERS
957 is not used any more in any critical section so WHOIS can
958 be used even though it might be slower than IDENTIFY.
960 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
963 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Changed the protocol API a bit more consistent in the
966 lib/silccore/silcprotocol.[ch].
968 * Changed the following headers to ROBODoc format:
970 lib/silccore/silcpayload.h
971 lib/silccore/silcprotocol.h
972 lib/silccore/silcsockconn.h
974 All core library headers are now formatted.
976 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Fixed a bug in Irssi SILC client; do not show that you are
979 server/router operator if you really are not. Affected file is
980 irssi/src/silc/core/client_ops.c.
982 * Renamed silc_command_free_payload to silc_command_payload_free.
983 Affected file lib/silccore/silccommand.h
985 * Added silcmath.h to include the prototoypes of various routines
986 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
989 * Changed the following headers to ROBODoc format:
991 lib/silccore/silcchannel.h
992 lib/silccore/silccommand.h
993 lib/silccore/silcid.h
994 lib/silccore/silcidcache.h
995 lib/silccore/silcmode.h
996 lib/silccore/silcnotify.h
997 lib/silccore/silcpacket.h
998 lib/silcmath/silcmath.h
1000 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Added checking to the server code not to start the server if
1003 ciphers and stuff are not configured properly. Affected files
1004 silcd/serverconfig.[h] and silcd/server.c.
1006 * Changed the layout of the header files of the public interfaces
1007 in the SILC libraries. The new layout supports ROBODoc
1008 documentation tool (and some others) so that it is easy to create
1009 a library reference manual. All the other headers and source
1010 code must still follow the CodingStyle document. Also source
1011 code must not include these ROBODoc stuffs, only the headers.
1012 Furthermore, all public interface headers must now be named
1013 by using `silc' prefix, example: silcapi.h, silccipher.h.
1014 Some files were renamed due to this. All the other headers
1015 must not be used as public interfaces. I will update the
1016 CodingStyle document later. Changed following headers, so far:
1018 lib/silcclient/silcapi.h
1019 lib/silccore/silcauth.h
1020 lib/silccore/silcprivate.h
1021 lib/silccrypt/silcdh.h
1023 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Removed silc_client_packet_send_flush from the client library
1028 as it is not needed. Affected file lib/silcclient/client.[ch].
1030 * Added printing of message of unresolved authentication method
1031 to the Irssi SILC client. Added it to the module formats.
1032 Removed the same message from the client library.
1034 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Added new distribution feature, DISTLABEL. Every distribution
1037 can define own preprocessor label that can be used in the
1038 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1039 file distributions, acconfig.h.pre and prepare.
1041 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1043 * Added Makefile.defines_int to include the actual definitions
1044 for Makefile.defines.in. Tested the new distribution system,
1045 created distributions and tested installation.
1047 * Added AWAY message printing to the Irssi SILC client. Added
1048 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1050 * Added SCONNECT command to call the SILC's CONNECT command.
1051 Cannot use CONNECT directly since Irssi uses that internally.
1052 Affected file irssi/src/silc/core/silc-servers.c.
1054 Added ACTION local command. It is same as ME command but takes
1055 the channel as mandatory argument.
1057 Rewrote some of the Irssi's help files to suite for SILC
1060 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1062 * Added Makefile.defines[.in] that should for now on be included
1063 in all Makefile.am file in the source tree. That file includes
1064 all common compilation definitions for SILC source tree.
1066 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Minor changes to the ./prepare script to change the package
1069 name according the distribution name to the configure.in.
1071 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Created new distribution system. Added file `distributions'
1074 that defines all the distributions that can be created out of
1075 the SILC source tree. The ./prepare script now reads that
1076 file to determine how to prepare the distributions. The
1077 first argument to the ./prepare is the name of the distribution
1078 and second is the version of the distribution. If given
1079 without arguments it creates the default (toolkit) distribution
1080 with the default version (defined in ./prepare).
1082 All Makefile.am files that are subject to the distributions
1083 are now named as Makefile.am.pre. These are ./Makefile.am
1084 and lib/Makefile.am. Others may be changed later.
1086 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Added invite list, ban list, some key management and connection
1089 error message printing to module formats in the Irssi SILC client.
1091 * Added new silc_client_set_away_message to set the away message
1092 that is back to the person who sent private message. The
1093 affected file lib/silcclient/silcapi.h and the
1094 lib/silcclient/client_prvmsg.c.
1096 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1098 * Fixed the private message sending in the Irssi SILC client,
1099 added local command KEY to the Irssi SILC client.
1101 Added key management and key agreement message formats to the
1102 irssi/src/fe-common/silc/module-formats.[ch].
1104 Added USERS (alias WHO) printing, server/router operator
1105 indication and LIST command printing to the module formats.
1107 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Fixed channel joining notify handling, cumode notify handling
1110 from Irssi SILC client.
1112 * Added SILC specific module-formats to the Irssi SILC client so
1113 that SILC specific message hilighting, colors etc is possible.
1114 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1116 Added channel mode, channel user mode, actions, notices,
1117 whois and whowas printing to the the module-formats.c.
1119 * Fixed a bug in channel deletion in the server. The channel
1120 is not left to the cache even if the channel founder auth mode
1121 is set when there are no users anymore on the channel. Affected
1122 file silcd/server.c.
1124 * The silc_net_localhost now resolves the entire hostname including
1125 the domain name. Affected file lib/silcutil/silcnet.c.
1127 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1129 * Changed the ask_passphrase client operation to be ascynchronous.
1130 It has now a completion callback and a context that the
1131 application must call after it has got the passphrase from
1132 the user. Affected files lib/silcclient/silcapi.h,
1133 lib/silcclient/protocol.c, lib/silcclient/command.c and
1136 Added SilcAskPassphrase callback that the application calls
1137 to deliver the passphrase to the library.
1139 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1140 The public key verification and especially a certificate
1141 verification is asynchronous procedure.
1143 Added new SILC_SKE_STATUS_PENDING status to indicate the
1144 request is pending and a callback will be called to finalize
1147 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1148 indicate that remote end did not send its public key (or
1149 certificate), even though we require it. Added check for this
1150 condition in the SKE. This was a security bug, now fixed.
1152 Defined new SilcSKEVerifyCbCompletion callback that is called
1153 when the verification process is completed.
1155 The affected files lib/silcske/silcske_status.h and
1156 lib/silcske/silcske.[ch].
1158 * Changed the verify_public_key client operation to be async
1159 as well. Defined SilcVerifyPublicKey callback that is used to
1160 indicate the success of the public key verification process.
1162 Changed the server and client to use the new async client
1165 * Changed the Irssi SILC client's internal scheduler to be called
1166 twice as many times as it used to be. As a result the client
1167 should be a bit faster now. Affected file is
1168 irssi/src/silc/core/silc-core.c.
1170 * Added support to Irssi SILC client of asynchronous public key
1171 verification and passphrase inquiry. Affected file is
1172 irssi/src/silc/core/silc-core.c.
1174 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * Do not say "You have left channel %s" in client library.
1177 Moved it to the application. Affected files are
1178 lib/silcclient/command.c and silc/client_ops.c.
1180 * Fixed silc_client_get_clients. Command context was not
1181 duplicated and was freed memory in the callback. Affected
1182 file lib/silcclient/idlist.c.
1184 * Do not say "you are now talking..." on JOIN command in the
1185 client library. The appliation must handle it.
1187 * Do not say ".. changed topic to" in command reply in the
1188 client libary. The application must handle it.
1190 * Fixed TOPIC command sending in the client library.
1192 * Fixed a memory leak in silc_client_command_free in the file
1193 lib/silcclient/command.c.
1195 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1197 * Imported a modified version of Irssi client to the source tree.
1198 The Irssi will be used to create a new client called
1199 Irssi SILC. Imported to irssi/.
1201 Added silc_core_init_finish function to the Irssi. Affected
1202 file irssi/configure.in.
1204 A lot changes in the Makefile.ams around the irssi tree.
1206 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Do not rehash if the new size is same as the old size of the
1209 hash table, in the silc_hash_table_rehash*. The affected file
1210 lib/silcutil/silchashtable.c.
1212 * Replaced hash_table_del_by_context calls from the server
1213 (when channel->user_list and client->channels) to the
1214 hash_table_del as it is sufficient and faster.
1216 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Added silc_hash_table_list, silc_hash_table_get and the
1219 SilcHashTableList structure to provide an alternative way to
1220 traverse the hash table. The affected files are
1221 lib/silcutil/silchashtable.[ch].
1223 * Changed the server's idlist routines to use the hash table
1224 routines to optimize the code.
1226 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * Replaced the client entry's `channel' list and channel entry's
1229 `user_list' list to hash tables for optimized lookup. Changed
1230 the code to use the hash table interface around the code.
1231 Affected file lib/silcd/idlist.[ch].
1233 * Added `auto_rehash' boolean argument to the function
1234 silc_hash_table_alloc to indicate whether the hash table should
1235 auto-rehash when it thinks is appropriate time. It will
1236 increase the hash table size if the there is twice as much
1237 entries in the table than the size of the table, and will
1238 decrease the size if there are twice as less entries than
1239 the size of the table.
1241 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1245 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * silc_idcache_purge_by_context deletes the entry now by context
1248 as it is supposed to do. Affected file lib/silccore/idcache.c.
1250 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1251 client is not anymore valid (WHOWAS givens the info) and not
1252 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1254 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * Removed the `data' and `data_len' arguments from the ID Cache
1257 interfaces and added `name' argument. ID Cache does not handle
1258 anymore the binary data only a names associated with given ID.
1260 * When hashing a Client ID with silc_hash_id the entire ID is
1261 not hashed anymore, instead only the hash of the Client ID is
1262 hashed. This way we can access the Client ID from the cache
1263 with Client ID but with the hash of the ID (which is a hash of
1264 the nickname) as well without any difference in performance.
1266 Added also silc_idcache_find_by_id_one_ext to do one on one
1267 searching when we have the actual ID. Added also function
1268 silc_hash_client_id_compare. The affected files are
1269 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1271 * When hashing the name associated with a ID it is always done
1272 in lowercase. This way we can access the cache without worrying
1273 about case-sensitivity, even though, for example nicknames are
1276 * Fixed a bug in server with channel message sending. It put
1277 wrong ID type as destination ID. The affected file
1278 silcd/packet_send.c.
1280 * silc_idcache_del_by_context now deletes from all hash tables
1281 by context. Affected file lib/silccore/idcache.c.
1283 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Changed the client library to use the new ID Cache interface.
1286 Changes around the source tree.
1288 * Added silc_hash_table_rehash_ext to rehash with specific
1289 hash function. Affected file lib/silcutil/silchashtable.[ch].
1291 * Added silc_hash_string_compare to compare two strings in the
1292 hash table. Affected file lib/silcutil/silcutil.[ch].
1294 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Added new function silc_idcache_del_by_context into the
1297 lib/silccore/idcache.[ch].
1299 * Changed the server's ID list routines to use the new ID Cache
1300 interface. Changes around the source tree.
1302 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Added silc_hash_table_del[_by_context]_ext functions in to the
1305 lib/silcutil/silchashtable.[ch].
1307 Removed silc_hash_table_find_all* routines and added new
1308 silc_hash_table_find_foreach to replace them.
1310 Added silc_hash_table_replace_ext function as extended
1311 replacing function. Separated the simple hash table interface
1312 from the extended hash table interface in the file
1313 lib/silcutil/silchashtable.h.
1315 * Fixed minor bugs and changed it to use some of the new
1316 hash table functions in lib/silccore/idcache.c
1318 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Added new function silc_hash_table_find_all to return all keys
1321 in the hash table by the specified key. As the hash table is
1322 collision resistant it also makes it possible to have several
1323 duplicate keys in the hash table. This function may be used to
1324 find all of the keys from the hash.
1326 Added user_context arguments to the SilcHashFunction,
1327 SilcHashCompare and SilcHashDestructor to deliver user specified
1330 Added new fuctions silc_hash_table_find[_all]_ext to do
1331 extended lookup with specified hash and compare functions and
1332 specified user contexts.
1334 Added new function silc_hash_table_add_ext to add the key
1335 with specified hash function and user context.
1337 Added new function silc_hash_table_foreach to traverse all
1338 entrys in the hash table. Added SilcHashForeach callback
1341 Added new function silc_hash_table_del_by_context to delete
1342 the entry only if the context associated with the key matches.
1344 Affected files are lib/silcutil/silchashtable.[ch].
1346 * Removed silc_hash_[server/client/channel]_id and added just
1347 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1348 silc_hash_id_compare to compare two ID's using as the hash table
1349 comparison function. Added also silc_hash_data to hash
1350 binary data and silc_hash_data_compare to compare it.
1352 * Removed silc_idlist_find_client_by_hash as it is not needed
1353 anymore. Affected file silcd/idlist.[ch].
1355 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1356 to use internally the SilcHashTable. The new ID Cache is a lot
1357 faster than the old one. Some of the ID Cache interface was also
1358 rewritten and obsolete and stupid functions were removed.
1360 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1362 * Added entry_count field to the SilcHashTable to keep the number
1363 of the entries in the table. Implemented the function
1364 silc_hash_table_rehash. Added new function
1365 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1367 Fixed a minor bug in silc_hash_table_free.
1369 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1370 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1371 into the lib/silcutil/silcutil.[ch].
1373 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1375 * Implemented a collision resistant hash table into the
1376 lib/silcutil/silchashtable[ch]. See the header and the source
1377 for the SilcHashTable API.
1379 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Merged dotconf version 1.0.2 into lib/dotconf.
1383 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Do not compile anything in lib/silcsim/* if the SIM support
1386 is not enabled. The tree should now compile without problems
1389 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1391 * Compiled the SILC under cygwin. Compiled and tested briefly
1392 without problems. More tests needed. The SIMs didn't compile
1395 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1397 * Fixed possible crash in silc_get_username in the
1398 lib/silcutil/silcutil.c.
1400 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed a va_arg in silc/client_ops.c.
1404 * Oops, RC5 routines were named AES and caused some problems
1405 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1407 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Added new SilcIDIP structure into the lib/silccore/id.h and
1410 replaced the old `ip' fields from all SILC ID's to that type.
1411 This is a step towards IPv6 support.
1413 The silc_id_get_len takes now the ID as an extra argument.
1414 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1415 both IPv4 and IPv6 based ID's.
1417 The affected files are lib/silccore/id.[ch] and other files
1418 around the tree using these routines.
1420 * Removed the ID length arguments in server from various
1421 silc_server_send_notify_* routines -> they are not needed
1424 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1426 * Fixed memory leak in silc_encode_pem_file in the file
1427 lib/silcutil/silcutil.c.
1429 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Check minor version as well in the SKE. Affected files are
1432 silcd/protocol.c and lib/silcclient/protocol.c.
1434 * Added --identifier option to the server so that an identifier
1435 can be when creating the public key for the server. Affected
1436 file is silcd/silcd.c.
1438 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1439 lib/silccrypt/silcpkcs.c.
1441 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Register default ciphers and stuff when using -C option with
1444 the server. Affected file sildc/silcd.c.
1446 * Put back the servers public key filename format, it is better
1447 than the new one. For now, the client keys are saved with the
1448 new filename format. The affected file silc/client_ops.c.
1450 * Implemented the Cipher API for the rest of the ciphers that
1451 did not implement it or implemented it the wrong way.
1453 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Register default ciphers and stuff when using the -S option
1456 in the client. Affected file silc/silc.c. Same also when
1457 creating new key pair with -C option.
1459 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Fixed the silc_verify_public_key client operation function to
1462 save the public keys differently. The fingerprint is now
1463 used as filename and not the hostname. This way also the
1464 client keys are saved uniquely and not with hostnames. The
1465 affected file is silc/client_ops.c.
1467 * Trimmed the silc_hash_fingerprint function to remove extra
1468 whitespaces from the end of the fingerprint. The affected
1469 file is lib/silccrypt/silchash.c.
1473 * Added silc_cipher_register_default function to register all
1474 default ciphers. It can be used when configuration files
1475 does not exist and the application does not want any specific
1476 ciphers in any specific order.
1478 The SilcDList is now used as silc_cipher_list dynamically
1479 allocated cipher list. Removed the static list all together
1480 and now all ciphers must be allocated to the dynamic list.
1481 The silc_cipher_alloc routine was changed to check only the
1484 All silc_cipher_* routines that used to return int returns
1487 The affected files lib/silccrypt/silccrypt.[ch].
1489 * The same thing was done to silc_hash_* as for silc_cipher_*
1490 routines. Affected files lib/silccrypt/silchash.[ch].
1492 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1493 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1494 Added also silc_pkcs_[un]register[_default] functions.
1495 Removed the data_context from the PKCS API.
1497 * Added silc_hmac_register_default function to register default
1498 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1499 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1500 to unregister all hmacs at once.
1502 * Register the default ciphers, hash functions, PKCSs and HMACs
1503 if client's configuration file does not exist. The affected
1506 * The client did not load the hash functions from the SIM
1507 modules at all. Added support for this. Affected file is
1508 silc/clientconfig.c.
1510 * When decoding public key with silc_pkcs_public_key_decode, check
1511 the supported algorithm only if PKCS are registered. Affected
1512 file lib/silccrypt/silcpkcs.c. The same was done with the
1513 silc_pkcs_private_key_decode.
1515 * Fixed the SILC List routines to keep the list always in order.
1516 It used to change the list's order when traversing the list but
1517 not it preserves the order. Affected file lib/trq/silclist.h.
1519 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Added the client library to use the SilcSocketConnection's
1522 reference counter (by silc_socket_dup) to prevent the bug that
1523 the socket object may be freed underneath async operation.
1525 * The name resolv library checking fixes in the configure.in.pre.
1528 * Created new version of the protocol drafts for future
1529 development. The -03 drafts are the ones that will be changed
1530 in the trunk now and the -02 will remain as they are.
1532 * Send list of CUMODE notifys to the router when announcing
1533 the channel users to the router. Affected file silcd/server.c.
1534 If the router receiving channel founder CUMODE for a channel
1535 that already has channel founder it will send CUMODE notify
1536 to the sender to remove the channel founder rights from the
1537 announced client. Affected file silcd/packet_receive.c.
1539 * The CUMODE notify may now use Server ID as well as the entity
1540 who changes the mode. Updated protocool specs.
1542 * Updated INSTALL and README files.
1544 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * New web pages in the http://silc.pspt.fi. The pages was
1551 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Implemented the [DenyConnectin] config section in the server.
1554 Added silc_server_config_denied_conn to check whether incoming
1555 connection is denied. Affected file silcd/serverconfig.[ch].
1557 * Do not check the ports when checking the incoming configuration
1558 data if the port is 0, meaning any. Affected file is
1559 silcd/serverconfig.c.
1561 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Fixed buffer overflow in silc_string_compare in the file
1564 lib/silcutil/silcutil.c.
1566 * Fixed double free in silc_server_command_leave in the file
1569 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Fixed the version checking in the server. Affected file is
1574 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Fixed the configuration data fetching when accepting new
1577 connections in the server. Affected file silcd/server.c.
1579 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Added `sender_entry' argument to the function
1582 silc_server_packet_relay_to_channel so that we can check
1583 whether some destination actually belongs to the same route
1584 the sender belongs (ie, we must not resend the packet to the
1585 sender). Affected file silcd/packet_send.[ch].
1587 * Added `servername' field to the SilcClientEntry in the server
1588 to hold the name of the server where client is from. Affected
1589 file is silcd/idlist.h.
1591 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Moved the channel message encrypting in the router betwen
1594 router connections from silc_server_channel_message to the
1595 silc_server_packet_relay_to_channel since we want to check
1596 whether we have anybody channel before encrypting anything.
1597 Affected files silcd/packet_[receive/send].c.
1599 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Fixed the [AdminConnection] server config section to support
1602 multiple entries. Affected file silcd/serverconfig.c.
1604 * Added support into the server to check the validity of the
1605 incoming connection before executing any KE or authentication
1608 * The connection configuration is now saved to the KE and
1609 connection auth protocol contexts and not fetched anymore in
1610 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1612 * The local hosts listenning address and port is also resolved
1613 now when starting the server. We want to have the socket object
1614 to include the real address and port for the listener. Added
1615 new function silc_net_check_local_by_sock into the files
1616 lib/silcutil/silcnet.[ch].
1618 * Fixed a broadcast bug in server -> do not broadcast if we
1621 * Fixed a routing bug. Do not route broadcast packets ever.
1622 Broadcast packets must be processed always and not routed since
1623 they may be destined to some other host than yourself and thus
1624 would get routed without no good reason. Affected file is
1627 * Added function silc_server_config_is_primary_route to check
1628 whether primary router connection has been configured (a router
1629 configuration that we are initiating). If there is not, we
1630 will assume that there is only two routers in the SILC network
1631 and we will use the incoming router connection as our primary
1632 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1634 * Changed the order of the broadcasting. Broadcast _after_ the
1635 packet has been processed not before. Affected file is
1638 * Fixed a [ClientConnection] parsing bug. The port was never
1639 parsed correctly thus resulting to port 0. Affected file
1640 silcd/serverconfig.c.
1642 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1643 argument and did not set the broadcast packet flag. Affected
1644 file silcd/packet_send.c. Fixed same bug in the function
1645 silc_server_send_notify as well.
1647 * If we receive NEW_ID packet for our own ID in the server, ignore
1650 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1654 * Removed the nickname from the Private Message Payload.
1655 Updated the code and the protocol specs.
1657 * Updated protocol specs for submitting to the IETF.
1659 * Tweaked the Random Number Generator a bit. Affected file
1660 lib/silccrypt/silcrng.c. Exported a new function
1661 silc_rng_[global]_add_noise which can be used to add more
1664 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Do not parse packets with different timeout when protocol
1667 is active -> may cause problem with rekey. Affected file
1670 * When server receives signoff notify it must not create
1671 new channel key if the client is on any channels since the
1672 sender of the signoff notify will create it.
1674 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Added printing of error messages during SKE protocol from the
1677 failure packet sent by server during SKE. Affected file
1680 * Removed the client's failure_callback handling with timeout
1681 and handle it immediately when received.
1683 * The SKE library returned wrong type in SUCCESS and FAILURE
1684 packets. They must be 32 bit MSB not 16 bit MSB.
1686 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Ok, rewrote the logic of the re-key and now it seems to work.
1689 I tested it on high traffic with frequent re-keys without
1690 problems. Added hmac_receive (and renamed hmac to hmac_send)
1691 in SilcClientConnection in lib/silcclient/client.h and
1692 in SilcIDListData in silcd/idlist.h. Also, removed the
1693 SilcPacketParserContext's cipher and hmac fields as they are
1694 not needed anymore and actually caused some problems when
1695 the ciphers and hmac's changed underneath the packet parser.
1697 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1699 * If re-key protocol is active then process the incoming packets
1700 synchronously since we must assure that icoming packets encrypted
1701 with the old key is processed before the new keys is set to
1702 use. This is true other packets than for REKEY packets.
1703 Affected file silcd/server.c. The same was done to client library
1704 as well, affected file lib/silcclient/client.c.
1706 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Fixed bug in client and server to accept the force send if
1709 the packet is send from silc_[server/client]_packet_process
1710 function. Otherwise the packets are never delivered, oops.
1712 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Disable force sending of packets when REKEY protocol is active.
1715 We must assure that no packet is sent directly when rekey is
1716 performed. All packets must be sent through packet queue.
1717 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1718 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1719 function is silc_[server/client]_packet_send_real to check
1722 * Replaced the SIM paths from example config files to
1723 /usr/local/modules. Also, make install creates now
1724 /usr/local/silc/logs directory to hold all the SILC server
1727 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Made the configure.in.pre work on Solaris. Patch by salo.
1731 * Made all ciphers compatible with non-x86 machines. Defined
1732 CBC mode macros into lib/silccrypt/ciphers_def.h.
1734 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Fixed the make install.
1738 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * When MAC computation fails the silc_packet_decrypt returned 0
1741 even though it was supposed to return -1. Fixed this. The
1742 affected file is lib/silccore/silcpacket.c.
1744 * Do not replace the config files in /etc/silc (in make install)
1745 if they already exist. Affected file ./Makefile.am.
1747 * Do not send re-key packets immediately but through packet queue.
1748 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1750 * Changed silc_net_check_host_by_sock to return FALSE if the
1751 IP/DNS could not be resolved. Though, it returns the IP address
1752 now even if it could not resolve it (but returns also FALSE).
1753 Affected file lib/silcutil/silcnet.[ch].
1755 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Added silc_pkcs_decode_identifier to decode the public key's
1758 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1759 Added also silc_pkcs_free_identifier. Added also new context
1760 SilcPublicKeyIdentifier.
1762 * Added -S option to the silc client. It is used to dump the
1763 contents of the specified public key file.
1765 * Changed the PKCS api to return the public key length when
1766 setting the public key.
1768 * Fixed a fatal bug in the public and private key file loading.
1769 Affected file lib/silccrypt/silcpkcs.c.
1771 * Execute the packet parsing for client with zero (0) timeout
1772 if the protocol is active. Affected file silcd/server.c.
1774 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Made the key generation options to the silcd program. Added
1777 -C option, equivalent to client's option.
1779 * Added new [ServerKeys] config section to the server. It
1780 configures the server's public and private key.
1782 * Defined generic Public Key Payload into the protocol
1783 specification to send specific type of public keys and
1786 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1787 public key or certificate.
1789 * Implemented the GETKEY command to the server and to the
1790 client library and on user interface.
1792 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Made preliminary `make install' work.
1796 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Added SilcServerRekey context into silcd/idlist.h.
1800 * Added the PFS support as defined in the specification to the
1801 SKE protocol. Affected files lib/silcske/*.c.
1803 * Added `ske_group' field to the SilcServerRekey context to hold
1804 the number of the SKE group that is used with PFS in re-key.
1805 Affected file silcd/idlist.h.
1807 * Added PFS re-key support to the server. Affected file is
1810 * Added silc_protocol_cancel to cancel execution of the next
1811 state of the protocol. Affected file is
1812 lib/silccore/silcprotocol.[ch].
1814 * Added the re-key support with and without PFS to the client
1815 library. Re-key is performed once in an hour, by default.
1817 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1818 Added silc_client_rekey_callback and silc_client_rekey_final.
1819 Affected files are lib/silcclient/protocol.[ch] and
1820 lib/silcclient/client.[ch].
1822 * Removed the `hmac_key' and `hmac_key_len' fields from the
1823 SilcClientConnection structure; not needed. Affected file is
1824 lib/silcclient/client.h.
1828 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * Do not ask whether user wants to use the negotiated private key
1831 for private messages, just use it. Affected file is
1832 silc/local_command.c.
1834 * Added `send_enc_key' and `enc_key_len' fields to the
1835 SilcIDListData structure since they are needed in the re-key
1836 phase. Affected file is silcd/idlist.[ch].
1838 * Implemented the simple re-key protocol into the server.
1839 Affected files silcd/server.c and silcd/protocol.[ch]. The
1840 re-key will be performed once in an hour, by default.
1842 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1843 Added silc_server_rekey, silc_server_rekey_callback and
1844 silc_server_rekey_final.
1846 * Removed Tunneled flag from the protocol. Updated the code
1847 and the specifications.
1849 * Adde `pfs' field to the SilcIDListData to indicate whether
1850 the PFS is to be performed in the re-key. Affected file is
1853 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1856 int64 of at least the xintXX size. If void * is less that 4
1857 bytes uint32 * will be used. Defined bool as boolean.
1859 * Changed _ALL_ unsigned long and unsigned int to uint32,
1860 unsgined short to uint16 in the source tree.
1862 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1863 not handle clients that has entry->data.registered == FALSE.
1864 They are not in the network anymore. Affected file is
1867 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Implemented the sending of the SERVER_SIGNOFF notify in the
1870 server. Affected file is silcd/server.c.
1872 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1873 Added also silc_notify_payload_encode_args into the
1874 lib/silccore/silcnotify.[ch].
1876 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1877 Affected file silcd/packet_receive.c.
1879 * Implemented the SERVER_SIGNOFF notify handling in the client
1880 library. Affected file lib/silcclient/client_notify.c. Also,
1881 implemnted the printing of the SERVER_SIGNOFF info to the
1882 application. Affected file silc/client_ops.c.
1884 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1885 if the deleting was successful. Affected file silcd/idlist.[ch].
1887 * Added support for public key authentication in the connection
1888 authentication protocol in the client library. Affected file
1889 lib/silcclient/protocol.c.
1891 * Changed the server's silc_idlist_get_clients_by_* interface
1892 to support already allocated array so that new entries may be
1893 added to pre-allocated array. Affected file silcd/idlist.[ch].
1894 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1895 and command replies.
1897 * All command reply functions in the server now calls the
1898 pending command callback even if error occured. This way the
1899 error will be delivered to the client as well. Affected files
1900 silcd/command.c and silcd/command_reply.c.
1902 * Fixed INFO command to return local server's info if no server
1903 was provided. Affected file lib/silcclient/command.c.
1905 * Removed RESTART command for good. Updated the code and the
1908 * Rewrote parts of the task system. It is a bit simpler now.
1909 Removed unsued task priorities. The affected files are
1910 lib/silcutil/silctask.[ch].
1912 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Moved the USERS printing from the library to the application.
1915 Affected files lib/silcclient/command.c and silc/client_ops.c.
1917 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Added channel key re-key support. The re-key is perfomed
1922 only by the router and is done once in an hour. Added `rekey'
1923 field to the SilcChannelEntry in the server. Affected files
1924 silcd/server.c and silcd/idlist.h.
1926 * Added silc_task_unregister_by_context into the file
1927 lib/silcutil/silctask.[ch].
1929 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1931 * Added SILC_UMODE_GONE mode to indicate when the client is not
1932 present in the SILC network. Added also support to the local
1933 command AWAY that will set this mode. Added support of showing
1934 "xxx is gone" in WHOIS command. The USERS command shows the
1935 gone status as well.
1937 * Fixed setting server and router operator privileges in the
1938 server's UMODE command. Affected file silcd/command.c.
1940 * Merged the SKE KE1 and KE2 payloads into one payload. The
1941 new KE payload is equivalent to the old KE2 payload.
1943 Cleaned up the SKE Start Payload parsing. It now uses the
1944 simple buffer unformatting to do the parsing. A lot faster
1947 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1948 to the SKE that is used to indicate whether both of the SKE
1949 parties should perform authentication. By default only the
1950 responder performs authentication. By setting this flag also
1951 the initiator must do authentication. By default it is unset
1952 since in normal SKE case, client to server connection, only
1953 the responder should do authentication. When doing SKE between
1954 two clients both should perform authentication. Updated the
1955 code and the protocol specs.
1957 * A little fix to IDENTIFY command in the server. Search the
1958 client first by hash not nickname. Affected file is
1961 * Fixed the silc_client_close_connection to support closing
1962 the client to client connections wihtout deleting too much
1963 data. Affected file lib/silcclient/client.c.
1965 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1966 are received if protocol used to be active but is not anymore
1967 the application would crash due to NULL pointer dereference.
1968 Affected files silcd/server.c and lib/silcclient/client.c.
1970 * Added `hash' field to the SilcClientConnection to include
1971 the hash function negotiated in the SKE protocol.
1973 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1974 to set the channel founder authentication data. A client can
1975 claim the founder rights later by providing the authentication
1976 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1977 This way the channel founder can regain the channel founder
1978 privileges even it is left the channel. This works only on
1979 local server and the client must be connected to the same
1980 server to be able to regain the founder rights. Updated the
1981 protocol specs accordingly.
1983 Added support to the CMODE command in the client to set the
1984 founder auth data. Read the README to see how to set it.
1986 Added support to the CUMODE command to claim the founder
1987 rights. Read the README to see how to do it.
1989 Added support for the founder authentication to the Channel
1990 Entry in the server. Affected file silcd/idlist.h.
1992 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1993 server's CMODE command. Affected file silcd/command.c.
1995 * Added the following new functions into lib/silccore/silcauth.[ch]:
1996 silc_auth_get_method and silc_auth_get_data.
1998 * The server now saves the remote hosts public key to the
1999 SilcIDListData pointer. Affected file silcd/protocol.c.
2001 * The normal server now does not remove the channel entry from
2002 the cache if the founder authentication data is set. It used
2003 to remove it if the founder was the last one on the channel on
2004 the server and left the channel. The auth data is saved and
2005 if the channel is re-joined later the old entry is used with
2006 the old auth data. Affected files silcd/command_reply.c and
2009 * Removed the `pkcs' field from the SilcIDListData structure
2010 in the server; it is not used. Affected file silcd/idlist.h.
2012 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Fixed packet processing on slow links. Partial packets were
2015 never re-processed because the incoming data buffer was cleared
2016 by the application. Application must not directly clear the
2017 sock->inbuf, the packet processing routines handle it. Fixed
2018 this in client library and in server.
2020 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Fixed the WHOIS and IDENTIFY send reply function to really
2023 check whether to send list or just one entry. Affected file
2026 * Cleaned up the LEAVE command's channel key distribution. The
2027 affected file silcd/command.c.
2029 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2030 can enforce the channel mode as well. In that case the ID
2031 includes the ID of the server. The code now enforces the
2032 mode change if the router have different mode than the server.
2034 * The notify client operation with CMODE_CHANGE notify can now
2035 return NULL client_entry pointer if the CMODE was not changed
2036 by client. Application must check for this.
2038 * Added <Server ID> argument to INFO command to support server
2039 info fetching by Server ID.
2041 * Added silc_server_announce_get_channel_users to get assembled
2042 packets of channel users of the specified channel. Affected
2043 file silcd/server.[ch].
2045 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2046 was freed underneath the ID Cache.
2048 * Re-announce clients when the server received CHANNEL_CHANGE
2049 notify from the router. Affected file silcd/packet_send.c.
2051 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2053 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2054 crashed since it did not handle the fact that there is no cipher
2055 called "3" and didn't check the error condition. Now fixed.
2057 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2058 flag. It can be used to send message requests.
2060 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2062 * Implemented the RESTART command in the client.
2064 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2065 notice type messages. Added notice printing to the user
2068 * The channel keys are not re-generated if the channel's mode
2069 is PRIVKEY, ie private key on the channel exists. Affected
2070 files silcd/server.c and silcd/command.c.
2072 * Fixed a little bug in channel message delivery when channel
2073 private keys are set in the server. Affected file is
2074 silcd/packet_send.c.
2076 * Changed the setting on channel->on_channel = TRUE from the
2077 silc_client_save_channel_key to the JOIN command reply. The
2078 key payload is not received if the private channel key is set.
2079 Affected file lib/silcclient/command_reply.c and the
2080 lib/silcclient/client_channel.c.
2082 * When the CMODE_CHANGE notify is sent and the channel private
2083 key mode is removed the channel key must be re-generated in
2084 other cells as well. Added this support for the router in the
2085 silcd/packet_receive.c.
2087 * Added new local command NOTICE to send notice message on
2088 channel. Affected file silc/local_command.[ch].
2090 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added new local command ME to the client. It is used to send
2093 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2094 some action. Affected file silc/local_command.[ch].
2096 * Changed channel_message and private_message client operations
2097 to deliver the message flags to the application. Added also
2098 the `flags' arguments to the silc_client_send_channel_message
2099 and silc_client_send_private_message functions. Affected file
2102 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Redefined the Private Message Payload to support private message
2105 keys and to support the new private message flags. Updated
2106 the protocol specs. Flags makes it possible to have for example
2107 CTCP style messages.
2109 * Added new type SilcPrivateMessagePayload and defined an API
2110 for it in the lib/silcclient/silcprivate.[ch].
2112 * Tested private message private keys successfully. Tested the
2113 private message key set, unset and list commands with the new
2116 * Redefined the Channel Message Payload to include the channel
2117 message flags (equal with private message flags) to support
2118 for example CTCP style messages.
2120 * Defined some of the message (for channel and private message)
2121 flags. Updated the protocol specs and added the flags to the
2122 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2124 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Added SilcKeyAgreementStatus type to the key agreement routines
2127 to indicate the current status and error if one occured.
2128 The status types are defined in the lib/silcclient/silcapi.h.
2130 * Added new local command KEY that is used to set and unset private
2131 keys for channels, set and unset private keys for private messages
2132 with remote clients and to send key agreement requests and
2133 negotiate the key agreement protocol with remote client. The
2134 key agreement is supported only to negotiate private message keys,
2135 it currently cannot be used to negotiate private keys for channels,
2136 as it is not convenient for that purpose.
2138 * Fixed a minor pending callback setting bug in the function
2139 silc_client_get_client_by_id_resolve, now the function works.
2140 Affected file lib/silcclient/idlist.c.
2142 * Added function silc_net_get_local_port to get local bound
2143 port by socket. Added to lib/silcutil/silcnet.[ch].
2145 * Added `sockets' and `sockets_count' fields to the SilcClient
2146 object. They hold the sockets of the listenning sockets in
2147 the client. Listenning sockets may be for example the key
2148 agreement server. Affected file lib/silcclient/client.[ch].
2149 Added functions the silc_client_add_socket and the
2150 silc_client_del_socket. They are exported to the application
2153 * Added ~./silc/clientkeys to support other client's public keys.
2155 * Renamed verify_server_key client operation to verify_public_key
2156 and added one argument to indicate the type of the connection
2157 (server, client etc.).
2159 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Added silc_server_connection_auth_request to handle the
2162 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2163 silcd/packet_receive.[ch].
2165 * Added silc_server_send_connection_auth_request into the
2166 silcd/packet_send.c to send the connection auth request packet.
2168 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2171 * Fixed the public key authentication in responder side in the
2172 server. The `auth_data' pointer includes the SilcPublicKey
2173 not the path to the public key. Affected file silcd/protocol.c.
2175 * Implemented the public key authentication in the initiator side
2176 in the server. Affected file silcd/protocol.c.
2178 * Removed the [RedirectClient] config section from the server
2179 configuration. Is not needed and I don't want to implement it.
2181 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Cleaned up the CMODE command in the server. It now works
2184 correctly and supports all the modes defined in the protocol.
2185 Affected file is silcd/command.c.
2187 * Added `hmac_name' field to the SilcChannelEntry in the server
2188 to hold the default HMAC of the channel. It can be set when
2189 creating the channel (with JOIN command). Affected files
2192 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2193 type to indicate the change of the current cipher and hmac
2194 on the channel. Client can safely ignore the <cipher> argument
2195 (if it chooses to do so) since the CHANNEL_KEY packet will
2196 force the channel key change anyway. The <hmac> argument is
2197 important since the client is responsible of setting the new
2198 HMAC and the hmac key into use.
2200 * Fixed the CMODE command in the client library as well.
2202 * Tested CMODE command in router environment successfully.
2204 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Show the version of the remote client (or server) when connecting
2207 to the server. It is logged to the log file. Affected file
2208 is silcd/protocol.c.
2210 * Fixed the KILLED notify handling in the client library. The
2211 client must be removed from all channels when receiving the
2214 Also, do not remove the client entry when giving the KILL
2215 command but when the KILLED notify is received.
2217 * Removed silc_idlist_find_client_by_nickname from the server.
2218 Not needed anymore. Affected files silcd/idlist.[ch].
2220 * Implemented the CHANNEL_CHANGE notify type handling to the
2221 server. Affected file silcd/server.c.
2225 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Added silc_server_send_notify_invite to send the INVITE
2228 notify between routers.
2230 * Implemented the INVITE command correctly to the server.
2232 * Implemented the INVITE notify type handling in the server.
2234 * Implemented the INVITE command to the client library and on the
2237 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Added function silc_server_get_client_resolve to find the
2240 client entry by ID from all ID lists and then resolve it
2241 (using WHOIS) if it cannot be found. Affected file is
2244 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Implemented the BAN command to the client library.
2248 * The JOIN command in the server now checks the invite list
2251 * Changed the silc_command_reply_payload_encode_va and the
2252 silc_command_payload_encode_va to support that if argument is
2253 NULL it ignores and checks the next argument. Affected file
2254 lib/silccore/silccommand.c.
2256 * Added silc_server_send_notify_ban to send the BAN notify
2257 type between routers.
2259 * Chaned the silc_notify_payload_encode to support that if
2260 argument is NULL it ignores and checks the next argument.
2261 Affected file lib/silccore/silcnotify.c.
2263 * Tested ban lists in router environment successfully.
2265 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Implemented BAN command to the server, in silcd/command.[ch].
2269 * Removed the BAN and INVITE_LIST modes from the CMODE command
2272 * Added function silc_string_match to regex match two strings.
2273 Affected files lib/silcutil/silcutil.[ch].
2275 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Redefined parts of the SilcChannelEntry in the server to support
2278 the new ban and invite lists.
2280 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Redefined the INVITE command. The same command can be used to
2283 invite individuals to the channel but also to manage the invite
2284 list of the channel (to add to and remove from the invite list).
2285 Updated the protocol specs.
2287 * Added new command SILC_COMMAND_BAN that can be used to manage
2288 the ban list of the channel. Updated the protocol specs.
2290 * Removed the channel modes: the SILC_CMODE_BAN and the
2291 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2292 in the CMODE command. The equivalent features are now available
2293 using INVITE and BAN commands. Updated the protocol specs.
2295 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2296 in the network about change in the current ban list. The notify
2297 type is not used by the client.
2299 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2300 support the invite lists.
2302 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Added new function silc_string_regexify that converts string
2305 including wildcard characters into regex string that can
2306 be used by the GNU regex library. Added into the file
2307 lib/silcutil/silcutil.[ch].
2309 Added silc_string_regex_combine to combine to regex strings
2310 into one so that they can be used as one regex string by
2311 the GNU regex library. Added into the file
2312 lib/silcutil/silcutil.[ch].
2314 Added silc_string_regex_match to match two strings. It returns
2315 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2317 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Imported GNU regex to the soruce tree into lib/contrib.
2320 Fixed some compiler warning from the regex.c.
2322 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Fixed MOTD command in the server to work in router environment.
2326 * Fixed the MOTD command in the client library to support
2327 the server argument in the command.
2329 * Added `nickname_len' argument to the silc_idlist_add_client
2330 in the server, as the `nickname' argument may be binary data
2333 * Added silc_idlist_get_channels to return all channels from
2336 * Implemented LIST command to the server. Affected file is
2339 * Implemented the LIST command to the client library and on the
2342 * Added [<user count>] argument to the LIST command reply.
2343 With private channels the user count is not shown.
2345 * Updated TODO and README.
2347 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * The client entry's data.registered must be TRUE even with
2350 global client entry on global client list. The data.registered
2351 is used to check whether the client is anymore in the network,
2352 for example with WHOWAS command so it must be valid.
2354 * Fixed the WHOWAS command in the server. It now actually works
2355 in router environment. Added function into silcd/command_reply.c
2356 silc_server_command_reply_whowas_save.
2358 * Added silc_idlist_purge function to the silcd/idlist.c
2359 to periodically purge the ID Cache.
2361 * Fixed INFO command in the server. It works now in router
2362 environment. Added <server name> argument to the INFO command
2363 reply. Updated the protocol specs.
2365 * Fixed minor bug in silc_idcache_purge to not purge if the
2366 expire value is zero.
2368 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2369 they were buggy because of the WHOWAS information.
2371 * Fixed local command MSG to handle the async resolving of
2372 the remote client properly. It used to fail the first MSG.
2373 Affected file silc/local_command.c.
2375 * Added `data_len' field to SilcIDCache context.
2377 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Update TODO. Todo in commands in the server.
2381 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2384 used by routers as broadcast packet to inform other routers
2385 about the changed user mode.
2387 Implemented the notify handling in the server. Affected file is
2388 silcd/packet_receive.c. Added the function
2389 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2391 * Added new generic Channel Payload and deprecated the New Channel
2392 Payload. The New Channel Payload is now the generic Channel
2395 * Added new argument `mode' to the silc_server_send_new_channel
2396 as it is required in the Channel Payload now.
2398 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2399 and created a new and real SilChannelPayload to represent the
2400 new generic Channel Payload. Implemented the encode/decode
2401 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2403 * Added silc_server_get_client_channel_list to return the list
2404 of channels the client has joined for WHOIS command reply.
2405 Affected file silcd/server.[ch].
2407 * Implemented the channel list sending in the WHOIS command reply
2408 in server and in the client.
2410 Implemented the channel list displaying on the user interface
2411 as well. Affected file silc/client_ops.c.
2413 * Added silc_channel_payload_parse_list to parse list of Channel
2414 Payloads. It returns SilcDList list of SilcChannelPayloads.
2415 Client for example can use this function to parse the list of
2416 channels it receives in the WHOIS command reply. The caller
2417 must free the list by calling silc_channel_payload_list_free.
2418 Affected files lib/silccore/silcchannel.[ch].
2420 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Added one new argument <user mode> to the WHOIS command reply
2423 to return the mode of the user in SILC. Updated the protocol
2426 Implemented it to the server and client.
2428 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Fixed the mode printing on the user interface on joining.
2431 Affected file silc/client_ops.c.
2433 * Implemented the UMODE command and user modes in general to the
2434 client library and to the user interface.
2436 * Implemented the UMODE command to the server.
2438 * The server now sends UNKNOWN_COMMAND error status if client sends
2439 unknown command. Affected file silcd/command.c.
2441 * All server commands now handle the command identifier the right
2442 way when sending the command reply to the client. The client can
2443 use to identify the command replies with the identifier.
2445 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * Added silc_server_get_client_route to resolve the route to
2448 the client indicated by the client ID. Affected file is
2451 * Added silc_server_relay_packet as general function to relay
2452 packet to arbitrary destination. This deprecates functions
2453 like _send_private_message_key, _relay_notify etc. Affected
2454 file is silcd/packet_send.[ch].
2456 Removed silc_server_send_key_agreement,
2457 silc_server_send_private_message_key and
2458 silc_server_packet_relay_notify functions from the file
2459 silcd/packet_send.[ch].
2463 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2464 server. Affected file silcd/packet_receive.[ch].
2466 * Implemented the KILL command to the client. Implemented the
2467 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2468 Affected files lib/silcclient/command[_reply].c and
2469 lib/silcclient/client_notify.c. Implemented the KILL notify
2470 printing in the user inteface.
2472 * Fixed a lot silc_parse_nick memory leaks from the client
2473 library in the file lib/silcclient/command.c.
2475 * Changed the silc_server_send_notify_on_channels's `sender'
2476 argument from SilcSocketConnection to SilcClientEntry to
2477 check the sender as entry and not as connection object and not
2478 to send to the client provided as argument. The affected file
2479 is silcd/packet_send.[ch].
2481 * The notify packets that are destined directly to the client used
2482 to not to be processed by the server. Now changed that and the
2483 server processes all notify packets. After relaying the packet
2484 to the client the notify packet is processed in the server.
2486 * The silc_server_free_client_data now checks whether there is
2487 pending outgoing traffic for the client and purges the data to
2488 the network before removing the client entry.
2490 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2493 an client is killed from the SILC Network. Updated the protocol
2496 Added new function silc_server_send_notify_killed to the
2497 silcd/packet_send.[ch].
2499 * Added function silc_server_packet_relay_notify to relay notify
2500 packets that are destined directly to a client. In this case
2501 the server does not process the notify packets but merely relays
2502 it to the client. Affected file silcd/packet_send.[ch].
2504 Added also silc_server_packet_process_relay_notify to check
2505 whereto relay the notify. Affected file is
2506 silcd/packet_receive.[ch].
2508 * Implemented the KILL command to the server.
2512 * Added the backup schema desgined last fall to the protocol
2513 specs for everyone to see. The specification is in the
2514 *-spec-xx.txt draft and the packet type definitions for the
2515 backup routers is in *-pp-xx.txt draft. Thusly, added also
2516 new packet type SILC_PACKET_CELL_ROUTERS.
2518 * A big security problem in the implementation discovered. The
2519 signoff of an client did not cause new channel key generation
2520 which it of course should've done. The channel keys must be
2521 always re-generated when client leaves (or signoffs) the channel.
2522 The silc_server_remove_from_channels funtion now handles
2523 the channel key re-generation.
2525 * Added `sender' argument to the silc_server_send_notify_on_channels
2526 to not to send the client provided as argument. Affected file
2527 silcd/packet_send.[ch].
2529 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Implemented OPER and SILCOPER commands into the server and
2534 * Added silc_auth_verify and silc_auth_verify_data to verify
2535 the authentication directly from the authentication payload.
2536 It supports verifying both passphrase and public key based
2537 authentication. Affected file lib/silccore/silcauth.[ch].
2539 * Added `hash' field to the SilcIDListData structure. It is the
2540 hash negotiated in the SKE protocol. Affected file is
2543 * Slight redesigning of the SilcAuthPayload handling routines.
2544 Do not send SilcPKCS but SilcPublicKey as argument.
2546 * Implemented the public key authentication support to the
2547 serverconfig. The public key is loaded from the provided path
2548 and saved as authentication data to void * pointer. Thus,
2549 changed the unsigned char *auth_data to void *auth_data;
2551 * Fixed SHUTDOWN command to send the reply before the server
2552 is shutdown. :) Affected file silcd/command.c.
2554 * Fixed fatal bug in CONNECT command. The hostname was invalid
2555 memory and server crashed. Affected file silcd/command.c.
2557 * Fixed fatal bug in CLOSE command. The server_entry became
2558 invalid but was referenced later in the command. Affected file
2561 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Fixed fatal bug in failure packet handling. Server ignored
2564 the failure and thus crashed when it came.
2568 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2571 that the command may be executed only once in (about) 2 seconds.
2572 The old SILC_CF_LAG flag is same but allows command bursts up
2573 to five before limiting.
2575 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2576 server code. Various commands now includes the CF_LAG_STRICT
2577 flag to disallow any kind of miss-use of the command.
2579 * Fixed the silc_buffer_unformat to not to allocate any data
2580 if the length of the data is zero. It used to allocate the
2581 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2583 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Changed the format of AdminConnection configuration section
2586 in the server. Added username of the admin to the format.
2587 Affected files silcd/serverconfig.[ch].
2589 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2590 to return admin configuration data by host, username and/or
2593 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Implemented WHOWAS command to the server. Added the functions:
2597 silc_server_command_whowas_parse,
2598 silc_server_command_whowas_send_reply,
2599 silc_server_command_whowas_from_client and
2600 silc_server_command_whowas_from_server
2602 * Added <Client ID> argument to the WHOWAS command reply. Updated
2603 the protocol specs accordingly.
2605 * Implemented WHOWAS command and command_reply to the client
2608 Implemented the WHOWAS printing on the user interface.
2610 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added new argument to the WHOWAS command reply, the real name.
2613 It is an optional argument. Updated the protocol specs.
2615 * Added SilcIDCacheDestructor callback that is registered when
2616 the SilcIDCache is allocated. The callback is called when
2617 an cache entry in the ID Cache expires, or is purged from the
2618 cache. Added into lib/silccore/idcache.[ch].
2620 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2621 to destruct the client entries when the cache entry expires.
2622 Other ID Cache's in server and in the client library ignores
2625 * If the ID Cache entry's `expire' field is zero then the entry
2626 never expires. Added boolean `expire' argument to the
2627 silc_idcache_add function in the lib/silccore/idcache.[ch].
2628 If it is TRUE the default expiry value is used.
2630 * Added silc_server_free_client_data_timeout that is registered
2631 when client disconnects. By default for 5 minutes we preserve
2632 the client entry for history - for WHOWAS command.
2634 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Added support to the server to enforce that commands are not
2637 executed more than once in 2 seconds. If server receives
2638 commands from client more frequently, timeout is registered
2639 to process the commands. Affected file silcd/command.c.
2640 Added new function silc_server_command_process_timeout.
2642 * Changed NICK_NOTIFY handling in client library to check that
2643 if the client's nickname was changed, so there is no need to
2644 resolve anything from the server.
2646 * Removed error printing from the WHOIS and IDENTIFY commands.
2647 If error occurs then it is ignored silently in the client library.
2648 The application, however, may map the received error to
2649 human readable error string. The application currently maps
2650 the NO_SUCH_NICKNAME error to string.
2652 * Made the command status message public to the application. Moved
2653 them from lib/silcclient/command_reply.c to
2654 lib/silcclient/command_reply.h. The application can map the
2655 received command status to the string with the
2656 silc_client_command_status_message function.
2658 * Added check to the server to check that client's ID is same
2659 as the Source ID in the packet the client sent. They must
2662 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Added dist-bzip hook to the Makefile.am to make bzip2
2665 compressed distributions.
2667 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Server now enforces the maximum length for the nickname and
2670 the channel as protocol specification dictates. 128 bytes for
2671 nickname and 256 bytes for channel name.
2673 * Moved the WHOIS printing to the application. The client libary
2674 does not print out the WHOIS information anymore, the application
2675 must do it. Renamed silc_client_command_reply_whois_print to
2676 the silc_client_command_reply_whois_save.
2678 The client's idle time is also sent to the application now, and
2679 the idle is shown on screen.
2681 * Added silc_client_command_reply_identify_save to save the
2682 received IDENTIFY entries.
2684 * Do not check for channel private keys in message sending and
2685 reception if the channel does not have the PRIVKEY mode set.
2686 Affected file lib/silclient/client_channel.c.
2688 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2691 just surfaced after chaning the JOIN procedure.
2693 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * Added silc_client_get_clients_by_list to get client entries
2696 from Client ID list, that is returned for example by JOIN
2697 and USERS command replies. The application should use this
2698 function for example when JOIN command reply is received to
2699 resolve the clients already on the channel (library does not
2700 do that anymore as USERS command reply is not used in the JOIN
2701 procedure anymore). Affected files lib/silcclient/silcapi.h and
2702 lib/silcclient/idlist.c.
2704 * JOIN command reply and USERS command reply returns now SilcBuffer
2705 pointers instead of unsigned char pointers when returning
2706 the client list and mode list.
2708 * Added <Client ID> argument to the JOIN command reply, mainly
2709 for the server to identify for which client the command was
2710 originally sent. Updated protocol specs accordingly.
2712 * Added SilcDlist private_key pointer to the SilcChannelEntry
2713 in the client to support the channel private keys. Affected
2714 file is lib/silcclient/idlist.h.
2716 * Added SilcChannelPrivateKey argument to the function
2717 silc_client_send_channel_message so that application can choose
2718 to use specific private ke if it wants to. If it is not provided,
2719 the normal channel key is used, unless private keys are set.
2720 In this case the first (key that was added first) is used
2721 as the encryption key.
2723 * Implemented the support for channel private key handling.
2724 Implemented the following functions:
2726 silc_client_add_channel_private_key,
2727 silc_client_del_channel_private_keys,
2728 silc_client_del_channel_private_key,
2729 silc_client_list_channel_private_keys and
2730 silc_client_free_channel_private_keys
2732 Affected file lib/silcclient/client_channel.c.
2734 * Added the support for the private keys in the channel message
2735 sending and encryption and in the message reception and
2736 decryption. Affected funtions are
2737 silc_client_send_channel_message and silc_client_channel_message.
2739 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Added SKE's key verify callback to the client library's
2742 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2744 * Removed the statement that server (or router) must send USERS
2745 command reply when joining to the channel so that the client
2746 knows who are on the channel. Instead, the client list and
2747 client's mode list is now sent in the JOIN command reply to the
2748 client who joined channel. This is better solution.
2750 * Added function silc_server_get_users_on_channel and function
2751 silc_server_save_users_on_channel to the silcd/server.[ch].
2753 * Removed function silc_server_command_send_users from the
2756 * Do not show topic on the client library anymore. The topic is
2757 sent in the command reply notify to the application and the
2758 application must show the topic now.
2760 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Added client searching by nickname hash into the IDENTIFY and
2763 WHOIS commands in the server as they were clearly missing from
2764 them. Affected file is silcd/command.c.
2766 * Fixed a bug in private message receiving in the client library.
2767 The remote ID was freed and it wasn't supposed, now it is
2770 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Minor fix to the channel payload; allocate the data area, as it
2773 needs to be of specific length.
2775 * If the key agreement port is zero then the operating
2776 system will define the bound port. Affected files are
2777 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2779 * Added new function silc_channel_payload_decrypt into the file
2780 lib/silccore/silcchannel.[ch].
2782 * Moved the channel message etc, check from silc_packet_decrypt
2783 to applications. The library calls now a generic
2784 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2785 when the packet is either normal or special. This was done to
2786 allow more wide range of checking that was not allowed when
2787 the code was in library. Now applications can do virtually any
2788 checks to the packet and return to the library the decision how
2789 the packet should be processed. Affected files are
2790 lib/silccore/silcpacket.[ch].
2792 Added silc_server_packet_decrypt_check to the server and
2793 silc_client_packet_decrypt_check to the client library.
2795 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2796 to send with specified source and destination information.
2798 * Channel message delivery between routers was broken after the
2799 channel key distribution was fixed earlier. The channel key
2800 was used be to distributed to other routers as well which is not
2801 allowed by the protocol. Now this is fixed and channel keys
2802 really are cell specific and the channel message delivery between
2803 routers comply with the protocol specification.
2805 * Fixed various commands in server to check also the global list
2806 for the channel entry and not just the local list. The affected
2807 file silcd/command.c.
2809 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Added assert()s to buffer formatting and unformatting routines
2812 to assert (if --enable-debug) when error occurs. Affected
2813 file: lib/silcutil/silcbuffmt.c.
2815 * Changed to auto-reconnect to check whether the remote host is
2816 router and register the re-connect timeout if it is. It used
2817 to check that whether we are normal server, but router must do
2818 auto-reconnect with another router as well. Affected file
2821 * Removed the [<key len>] option from CMODE command as the cipher
2822 name decides the key length, nowadays. See the defined ciphers
2823 from the protocol specification.
2825 * Added [<hmac>] option to the CMODE command to define the HMAC
2826 for the channel. Added SILC_CMODE_HMAC channel mode.
2828 * Added [<hmac>] option for the JOIN command so that user can
2829 select which HMAC is used to compute the MACs of the channel
2832 * Added Hmac field to the Channel Message Payload. The integrity
2833 of plaintext channel messages are now protected by computing
2834 MAC of the message and attaching the MAC to the payload. The
2835 MAC is encrypted. Now, it is clear that this causes some
2836 overhead to the size of the packet but rationale for this is that
2837 now the receiver can verify whether the channel message decrypted
2838 correctly and also when private keys are set for the channel the
2839 receiver can decrypt the packet with several keys and check from
2840 the MAC which key decrypted the message correctly.
2842 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2843 lib/silccrypt/silccipher.[ch].
2845 * Added silc_hash_len to return the digest length into the
2846 lib/silcrypt/silchash.[ch].
2848 * Rewrote parts of Silc Channel Payload interface in the
2849 lib/silccore/silcchannel.[ch]. The encode function now also
2850 encrypts the packet and parse function decrypts it.
2852 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Fixed a minor formatting bug in the SKE's key material processing.
2855 It actually might have processed the keys wrong way resulting
2858 * Redefined the mandatory HMAC algorithms and added new algorithms.
2859 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2860 and hmac-md5 truncated to 96 bits. The mandatory is now
2861 hmac-sha1-96. Rest are optional (including the one that used
2862 to be mandatory). Rationale for this is that the truncated HMAC
2863 length is sufficient from security point of view and can actually
2864 make the attack against the HMAC harder. Also, the truncated
2865 HMAC causes less overhead to the packets. See the RFC2104 for
2868 * Added new [hmac] configuration section. The SKE used to use
2869 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2870 is of course wrong. The official names that must be proposed in
2871 the SKE are the ones defined in the protocol specification
2872 (hmac-sha1-96 for example). The user can configure any hmac
2873 using any hash function configured in the [hash] section. At
2874 least, the mandatory must be configured.
2876 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2878 * Added HMAC list to the SKE proposal list. It has now both
2879 hash algorithm list and HMAC list. This makes the protocol
2880 incompatible with previous versions. The SKE now seems to work
2881 the way it is supposed to work, for the first time actually.
2883 * Defined plain Hash algorithms to the protocol specification.
2886 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Implemented support for key agreement packets into the server.
2889 Added functions silc_server_key_agreement and
2890 silc_server_send_key_agreement. Other than these functions,
2891 server has nothing to do with this packet.
2893 * Added support for private message key packets into the server.
2894 Added functions silc_server_private_message_key and
2895 silc_server_send_private_message_key.
2899 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2900 called in the protocol's final callback instead in the END
2901 protocol state. This makes a little more sense and in the same
2902 time in client we can use the same protocol routines for normal
2903 key exchange and to key agreement packet handling as well.
2905 * Added to both client's and server's KE protocol context the
2906 SilcSKEKeyMaterial pointer to save the key material. We will
2907 bring the key material to the protocol's final callback by doing
2908 this. The final callback must free the key material.
2910 * Added SKE's packet_send callback into client's KE protocol
2911 context so that the caller can choose what packet sending function
2912 is used. This way we can use different packet sending when
2913 doing normal SKE when doing key agreement packet handling (in
2914 the key agreement packet handling we do not want to encrypt
2917 * Implemented the responder side of the key agreement routines
2918 in the client. The client can now bind to specified port and
2919 accept incoming key negotiation. The key material is passed
2920 to the application after the protocol is over.
2922 * Implemented the processing of incoming Key Agreement packet
2923 in the client. Added function silc_client_key_agreement to
2926 * Implemented the intiator side of the key agreement routines
2927 in the client. The client can now initiate key agreement with
2928 another remote client. The key material is passed to the
2929 application after the protocol is over.
2931 * Created client_keyagr.c to include all the key agreement
2934 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2935 SILC_TASK_CALLBACK except that it is not static.
2937 * Created client_notify.c and moved the Notify packet handling
2938 from the client.[ch] into that file.
2940 * Created client_prvmsg.c and moved all private message and
2941 private message key routines from the client.[ch] into that file.
2943 * Create client_channel.c and moved all channel message and
2944 channel private key routines from the client.[ch] into that file.
2946 * Changed silc_client_get_client_by_id_resolve to resolve with
2947 WHOIS command instead of IDENTIFY command, in the file
2948 lib/silclient/idlist.c.
2950 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Implemented the SKE's responder side to the Client library.
2954 * When FAILURE is received to the protocol do not trust it
2955 blindly. Register a timeout to wait whether the remote closes
2956 the connection as it should do it, only after that process the
2957 actual failure. This was changed to both client and server.
2959 * Added client_internal.h to include some of the structures
2960 there instead of client.h in lib/silcclient/.
2962 * Added function silc_task_unregister_by_callback to unregister
2963 timeouts by the callback function.
2965 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Some "Incomplete WHOIS info" errors has been appearing on the
2968 log files. Took away the entry->userinfo check from WHOIS
2969 reply sending. The entry->userinfo is now " " if client did not
2970 provide one. I thought this was fixed earlier but something
2971 is wrong still. Let's see if the error still appears.
2973 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Fixed a minor bug in the login when the channel key is
2976 re-generated in the server. It used to generate the key in
2977 wrong order and thus caused problems in the channel traffic.
2979 * Fixed a minor bug in channel key distsribution after
2980 KICK command. The key was not sent to the router even though
2983 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2985 * Added silc_ske_process_key_material_data as generic routine
2986 to process any key material as the SILC protocol dictates. The
2987 function is used by the actual SKE library but can be used by
2988 applications as well. This relates to the private message keys
2989 and the channel private keys since they must be processed the
2990 same way the normal SILC session keys. The protocol dictates
2991 this. Affected files: lib/silcske/silcske.[ch].
2993 Added also silc_ske_free_key_material to free the
2994 SilcSKEKeyMaterial structure.
2996 * Defined silc_cipher_set_key function to set the key for
2997 cipher without using the object's method function. The affected
2998 files: lib/silccrypt/silccipher.[ch].
3000 * Implemented silc silc_client_add_private_message_key,
3001 silc_client_add_private_message_key_ske,
3002 silc_client_del_private_message_key,
3003 silc_client_list_private_message_keys and
3004 silc_client_free_private_message_keys functions in the
3007 Added functions silc_client_send_private_message_key to send
3008 the Private Message Key payload and silc_client_private_message_key
3009 to handle incoming Private Message Key payload.
3011 * Added Cipher field to the Private Message Key payload to set
3012 the cipher to be used. If ignored, the default cipher defined
3013 in the SILC protocol (aes-256-cbc) is used.
3015 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Removed lib/silcclient/ops.h file.
3019 Redefined parts of the SILC Client Library API. Created new
3020 file silcapi.h that deprecates the ops.h file and defines the
3021 published Client Library API. Defined also private message key
3022 API and channel private key API into the file.
3024 This is the file that the application must include from the
3025 SILC Client Library. Other files need not be included by
3026 the application anymore.
3028 * Added new key_agreement client operation callback and also
3029 defined the Key Agreement library API for the application.
3031 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3034 is used by clients to request key negotiation between another
3035 client in the SILC network. If the negotiation is started it
3036 is performed using the SKE protocol. The result of the
3037 negotiation, the secret key material, can be used for example
3038 as private message key.
3040 Implemented the Key Agreement payload into the files
3041 lib/silccore/silauth.[ch].
3043 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Redefined ciphers for the SILC protocol. Added some new ciphers
3046 and defined the key lengths for the algorithms. Changed the
3047 code accordingly. The default key length is now 256 bits.
3049 * Fixed SKE key distribution function silc_ske_process_key_material
3050 when the key length is more than 128 bits. The default key
3051 length in SILC is now 256 bits.
3053 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3054 to indicate unsupported algorithm.
3056 * Renamed rijndael.c to aes.c and all functions as well.
3058 * Fixed a long standing channel key setting bug in client library.
3059 Weird that it has never surfaced before.
3061 * Fixed bug in channel deletion. If the entire channel is removed
3062 then it must also delete the references of the channel entry
3063 from the client's channel list as the client's channel entry and
3064 the channel's client entry share same memory.
3066 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Implemented CONNECT and SHUTDOWN commands in the client.
3070 * Implemented CLOSE command to the client.
3072 * Added the function silc_idlist_find_server_by_name into the
3073 files silcd/idlist.[ch].
3075 Added the function silc_idlist_find_server_by_conn into the
3076 files silcd/idlist.[ch].
3078 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * DIE command was renamed to SHUTDOWN. Updated the both code
3083 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3084 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3086 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3089 * Added function silc_server_create_connection function to create
3090 connection to remote router. My server implementation actually
3091 does not allow router to connect to normal server (it expects
3092 that normal server always initiates the connection to the router)
3093 so the CONNECT command is only good for connecting to another
3096 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3099 or some other client was kicked from the channel.
3101 Implemented the handling of the notify type to both client
3104 Implemented silc_server_send_notify_kicked to send the KICKED
3105 notify. It is used to send it to the server's primary router.
3107 * Implemented the KICK command into server and client.
3109 * Added `query' argument to the silc_idlist_get_client function
3110 to indicate whether to query the client from server or not if
3113 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3114 to indicate that the client is not channel founder.
3118 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Removed the rng context from SilcPacketContext structure and
3121 changed that the packet routine uses the Global RNG API.
3123 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Added support for quit message that client can "leave" on the
3126 channel when it quits the SILC. It is ditributed inside the
3127 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3129 Added silc_server_free_client_data that will take the
3130 signoff message as argument.
3132 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3134 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Updated parts of the protocol specification to keep it up
3139 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3142 payloads in one packet.
3144 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3145 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3146 use now the new List flag.
3148 * Also deprecated the following packet types: REPLACE_ID,
3149 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3151 * Added list support for Notify packet in server.
3153 * Added silc_server_send_notify_channel_change to send the
3154 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3155 the silc_server_send_replace_id.
3157 * Added silc_server_send_notify_nick_change to send the
3158 NICK_CHANGE notify type. Deprecates the function
3159 silc_server_send_replace_id.
3161 * Added silc_server_send_notify_join to send the JOIN notify type.
3162 Deprecates the function silc_server_send_new_channel_user.
3164 * Added silc_server_send_notify_leave to send LEAVE notify type.
3165 Deprecates the function silc_server_send_remove_channel_user.
3167 * Added silc_server_send_notify_cmode and
3168 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3169 types. Deprecates the silc_server_send_set_mode function.
3171 * Added SERVER_SIGNOFF notify type to indicate that server has
3172 quit. This means that all clients on the channel from that
3173 server will drop. This can be also used when netsplit happens.
3175 Deprecated REMOVE_ID packet type since it is not needed anymore
3178 Added silc_server_send_notify_server_signoff to send the
3179 SERVER_SIGNOFF notify type. Deprecates the function
3180 silc_server_send_remove_id.
3182 Added also silc_server_send_notify_signoff to send the
3183 SIGNOFF notify type.
3185 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3186 SILC protocol from this day on. Changed the protocol
3187 specification as well.
3189 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3190 notify type. It is used between routers to notify about
3191 topic changes on a channel.
3193 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3196 * Partly updated the protocol specification to comply with the
3197 changes now made. It is still though a bit outdated.
3199 * The JOIN notify type now takes one extra argument <Channel ID>.
3200 The packet used to be destined to the channel but now the
3201 JOIN type may be sent as list thus it is impossible to
3202 destine it to any specific channel. By adding this argument
3203 it is again possible.
3205 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Added CREDITS file. The CHANGES and CREDITS file will appear
3208 in the distribution as well.
3210 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3213 types in the server's silcd/packet_receive.c.
3215 * Implemented CMODE and CUMODE to work in router environment.
3217 * Fixed minor encoding and decoding buglet from the
3218 lib/silccore/silcmode.c.
3220 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3223 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3225 * Changed all SilcConfigServer* and silc_config_server* to
3226 SilcServerConfig* and silc_server_config*, respectively.
3229 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Associated the ID (client or server ID) to the Authentication
3232 Payload to avoid any possibility of forging. Updated the
3233 protocol specification and the code accordingly.
3235 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * The RSA key length is now save to the RsaKey context in the
3238 key generation process in lib/silccrypt/rsa.c. The key length
3239 is now used to figure out the maximum size of the block allowed
3240 to be encrypted/signed.
3242 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3243 is equivalent to the silc_mp_mp2bin but does not allocate any
3246 * Changed silc_mp_mp2bin API to take length argument. If it is
3247 non-zero then the buffer is allocated that large. If zero, then
3248 the size is approximated using silc_mp_sizeinbase, which however
3251 * Created Global RNG API which is global RNG that application can
3252 initialize. After initializing, any routine anywhere in the
3253 code (including library) can use RNG without allocating a new
3254 RNG object. This was done to allow this sort of use of the
3255 RNG in code that has no chance to allocate RNG object. All
3256 applications currently allocate this and many routines in the
3257 library use this. Affected file lib/silccrypt/silcrng.[ch].
3259 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3260 it to use the Global RNG API.
3262 * Defined Authentication Payload into protocol specification that
3263 is used during SILC session to authenticate entities. It is
3264 used for example by client to authenticate itself to the server
3265 to obtain server operator privileges.
3267 Implemented this payload into the lib/silccore/silcauth.[ch].
3268 Implemented also routines for public key based authentication
3269 as the new protocol specification dictates.
3271 Moved definitions of different authentication methods from
3272 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3274 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3275 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3276 silc_pkcs_verify_with_hash functions into the file
3277 lib/silccrypt/silcpkcs.[ch].
3279 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * The client entry's userinfo pointer must be always valid.
3282 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3283 will fail since it requires the userinfo. Now, the userinfo
3284 is allocated as "" if actual userinfo does not exist. Actually,
3285 it must exist and it is totally Ok to drop client connections
3286 that does not announce the userinfo. However, we will make
3287 this workaround for now.
3289 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3290 to return the remote port by socket.
3292 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3295 SILC_SERVER_PENDING_EXEC and added an new macro
3296 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3297 data or when error occurs while processing the pending command.
3299 Added new argument `destructor' into silc_server_command_pending
3300 and to the SilcServerCommandPending object. This destructor is
3301 now called after calling the pending callback or if error occurs
3302 immediately. If error occurs the actual pending callback won't
3303 be called at all - only the destructor. The destructor may be
3304 NULL if destructor is not needed.
3306 All this applies for client library code as well. Similar
3307 changes were made there as well for the pending commands.
3309 In the client, the application must now allocate the
3310 SilcClientCommandContext with the silc_client_command_alloc
3313 * Added reference counter to the SilcServerCommandContext. Added
3314 function silc_server_command_alloc and silc_server_command_dup
3317 Same type of functions added to the client library for the same
3320 * Removed the cmd_ident from IDListData away since it is now
3321 global for all connections. It is the command identifier used
3322 in command sending and with pending commands. The affected file
3325 * Added reference counter to the SilcSocketConnection objecet to
3326 indicate the usage count of the object. The object won't be
3327 freed untill the reference counter hits zero. Currently only
3328 server uses this, and client ignores it. The client must be
3329 set to use this too later. The affected files are
3330 lib/silccore/silcsockconn.[ch]. Added also the function
3331 silc_socket_dup to increase the reference counter.
3333 This was mainly added because it is possible that the socket
3334 is removed underneath of pending command or other async
3335 operation. Now it won't be free'd and proper DISCONNECTING
3336 flags, etc. can be set to avoid sending data to connection that
3337 is not valid anymore.
3339 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3340 the connection. After that it sets SILC_SET_DISCONNECTED.
3341 It is, however, possible that the socket data is not still freed.
3342 The silc_server_packet_process now checks that data is not
3343 read or written to connection that is DISCONNECTED. The socket
3344 get's freed when the reference counter hits zero.
3346 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Changed the client operation API: channel_message operation's
3349 `sender' is now the client entry of the sender, not the nickname
3350 and the `channel' is the channel entry, not the channel name.
3352 In the private_message operation the `sender' is now also the
3353 client entry of the sender not the nickname.
3355 Affected file is lib/silcclient/ops.h and all applications
3356 using the client operations.
3358 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Moved the calling of ops->connect() from connect_to_server_final
3361 into receive_new_id functin since that is the point when the
3362 client is actually allowed to send traffic to network. The
3363 affected file is lib/silcclient/client.c.
3365 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3368 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3369 (if needs broadcasting) instead of broadcasting the packets one
3370 by one which would make a burst in the network traffic.
3372 * Added `broadcast' argument to the functions in silcd/server.[ch]
3373 silc_server_create_new_channel[_with_id] to indicate whether
3374 to send New Channel packet to primary router.
3376 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Added new function into the silcd/server.[ch] files:
3379 silc_server_create_new_channel_with_id to create new channel with
3380 already existing Channel ID.
3382 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3383 lib/silccore/silcpacket.h. This packet is used t send list of
3384 Set Mode payloads inside one packet. Server uses this to set
3385 the modes for the channels and clients on those channels, that it
3386 announced to the router when it connected to it. The protocol
3387 specification has been updated accordingly.
3389 * The silc_server_new_channel did not handle the packet coming
3390 from normal server as it normally does not send that. However,
3391 when it announces its channels it does send it. Implemented
3392 the support for that.
3394 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3395 into the file lib/silccore/id.h.
3397 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Fixed memory leaks in the functions silc_idlist_del_client,
3400 silc_idlist_del_channel and silc_idlist_del_server in the file
3401 silcd/idlist.c. All of those leaked like a sieve.
3403 * Fixed some small memory leaks in the client's function
3404 silc_client_notify_by_server.
3406 * Added functions into silcd/server.c: silc_server_announce_clients,
3407 silc_server_announce_channels and silc_server_announce_server.
3408 These functions are used by normal and router server to announce
3409 to its primary router about clients, channels and servers (when
3410 router) that we own. This is done after we've connected to the
3413 These functions effectively implements the following packet types:
3414 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3415 and SILC_PACKET_NEW_ID_LIST.
3417 * Added new functions into the silcd/packet_receive.[ch]:
3418 silc_server_new_id_list, silc_server_new_channel_list and
3419 silc_server_new_channel_user_list to handle the incoming
3420 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3422 * Added support of changing Channel ID in the function
3423 silc_server_replace_id. If the server that announces a channel
3424 to the router already exists in the router (with same name but
3425 with different Channel ID), router is responsible to send
3426 Replace ID packet to the server and force the server to change
3427 the Channel ID to the one router has.
3429 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3430 client that the Channel ID has been changed by the router. The
3431 normal server sends this to the client. Client must start using
3432 the new Channel ID as the channel's ID.
3434 Implemented handling of this new type into lib/silcclient/client.c
3435 into the function silc_client_notify_by_server.
3437 * Added new function silc_idlist_replace_channel_id into the files
3438 silcd/idlist.[ch] to replace the Channel ID.
3440 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Call silc_server_command_identify_check always when processing
3443 the IDENTIFY command in silcd/command.c
3445 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3448 send keepalive packets. The packet can be sent by clients,
3449 servers and routers.
3451 Added function silc_socket_set_heartbeat into the file
3452 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3453 If not set, the heartbeat is not performed. The actual
3454 heartbeat is implemented in the low level socket connection
3455 library. However, application is responsible of actually
3458 Added silc_server_send_heartbeat to send the actual heartbeat
3459 packet into silcd/packet_send.[ch]. Server now performs
3460 keepalive with all connections.
3462 * Added silc_task_get_first function into lib/silcutil/silctask.c
3463 to return the timeout task with shortest timeout. There was a bug
3464 in task unregistration that caused problems. TODO has been
3465 updated to include that task system must be rewritten.
3467 * The client library will now resolve the client information when
3468 receiving JOIN notify from server for client that we know but
3469 have incomplete information.
3471 * Rewrote parts of silc_server_remove_from_channels and
3472 silc_server_remove_from_one_channel as they did not remove the
3473 channel in some circumstances even though they should've.
3475 * Encryption problem encountered in server:
3477 The LEAVE command used to send the Channel Key packet to the
3478 router immediately after generating it. However, the code
3479 had earlier sent Remove Channel user packet but not immediately,
3480 ie. it was put to queue. The order of packets in the router
3481 was that Channel Key packet was first and Remove Channel User
3482 packet was second, even though they were encrypted in the
3483 reverse order. For this reason, MAC check failed. Now, this
3484 is fixed by not sending the Channel Key packet immediately but
3485 putting it to queue. However, this is more fundamental problem:
3486 packets that are in queue should actually not be encrypted
3487 because packets that are sent immediately gets encrypted
3488 actually with wrong IV (and thus MAC check fails). So, packets
3489 that are in queue should be encrypted when they are sent to
3490 the wire and not when they put to the queue.
3492 However, the problem is that the current system has not been
3493 designed to work that way. Instead, the packet is encrypted
3494 as soon as possible and left to the queue. The queue is then
3495 just purged into wire. There won't be any fixes for this
3496 any time soon. So, the current semantic for packet sending
3499 o If you send packet to remote host and do not force the send
3500 (the packet will be in queue) then all subsequent packets to the
3501 same remote host must also be put to the queue. Only after the
3502 queue has been purged is it safe again to force the packet
3505 o If you send all packets immediately then it safe to send
3506 any of subsequent packets through the queue, however, after
3507 the first packet is put to queue then any subsequent packets
3508 must also be put to the queue.
3510 Follow these rules and everything works fine.
3512 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Added new function silc_server_remove_clients_by_server to
3515 remove all client entries from ID list when the server connection
3516 is lost. In this case it is also important to invalidate all
3517 client entires as they hold the invalid server entry. This
3518 fixes fatal bug when server has lost connection and will reconnect
3521 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * Made some sanity checks to silc_server_daemonise like to check
3524 whether the requested user and group actually exists.
3526 * Added sanity check to SKE's silc_ske_responder_finish to check
3527 that the public and private key actually is valid.
3529 * Invalidate the client's nickname when receiving Replace ID
3530 packet and the Client ID is being replaced. This means that the
3531 server will query the nickname if someone needs it (client)
3534 * Sort the ID Cache in client library when the ID Cache data
3535 has changed (needs sorting).
3537 * Do not allow for SILC client to create several connections to
3538 several servers. The client does not support windows right now
3539 and generating multiple connections causes weird behaviour.
3541 Irssi-silc client does support windows and can handle several
3542 connections without problems, see: www.irssi.org and SILC plugin.
3544 * Fixed some places where client was added to the IDList. The
3545 rule of thumb is following (in order to get everything right):
3546 If the client is directly connected local client then the
3547 `connection' argument must be set and `router' argument must be
3548 NULL to silc_idlist_add_client function. If the client is not
3549 directly connected client then the `router' argument must
3550 bet set and the `connection' argument must be NULL to the
3551 silc_idlist_add_client function.
3553 * The funtion silc_server_packet_send_local_channel actually did
3554 not check whether the client was locally connected or not. It
3555 does that now. Fixed a bug related to LEAVE command.
3557 * Fixed Remove Channel User payload parsing bug in server's
3558 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3560 * The server's silc_server_save_channel_key now checks also the
3561 global ID list for the channel as it might not be in the local
3562 list. Fixed a bug related to LEAVE command.
3564 * Is this the end of the [<unknown>] buglet that has been lurking
3565 around for a long time? A little for loop fix in server's
3566 silc_server_command_whois_parse that is used by both IDENTIFY
3567 and WHOIS command. At least, this was a clear bug and a cause
3568 of one type of [<unknown>] buglet.
3570 * WHOIS and IDENTIFY commands call the function
3571 silc_server_command_[whois/identify]_check function even if
3572 we are not router server.
3574 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Added --with-gmp configuration option. If set the GMP
3577 is always compiled in the SILC source tree. If not set then
3578 it is checked whether the system has the GMP3 installed. If
3579 it has then the GMP won't be compiled (the system's headers
3580 and library is used), if it doesn't have it then the GMP is
3581 compiled in the SILC source tree.
3583 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Changed RSA private exponent generation to what PKCS #1
3586 suggests. We try to find the smallest possible d by doing
3587 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3588 not security fix but optimization.
3590 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Added new config entry [Identity] to fork the server and run
3593 it as specific user and group. A patch from Bostik.
3595 * Imported Dotconf configuration library into lib/dotconf.
3596 This will be used to create the SILC configuration files later.
3597 It will appear in the distsribution after this commit.
3599 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * A big code auditing weekend happening. Auditing code for
3602 obvious mistakes, bugs and errors. Also, removing any code
3605 Removed files for being obsolete:
3607 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3608 inline in the file lib/silcutil/silcbuffer.h)
3610 o lib/silcutil/silcbufutil.c (the header has inline versions)
3612 Changed code to fix possible error conditions:
3614 o The buffer formatting routines now check that the destination
3615 buffer really has enough space to add the data. This applies for
3616 both buffer formatting and unformatting
3617 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3618 unformatting was changed to accomodate following rules:
3619 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3620 sent to the function while XXX_*STRING will not allocate or copy
3621 the data into the buffer. Instead it sets the pointer from the
3622 buffer into the pointer sent as argument (XXX_*STRING used to
3623 require that the pointer must be allocated already). This change
3624 makes this whole thing a bit more consistent and more optimized
3625 (note that the data returned in the unformatting with XXX_*STRING
3626 must not be freed now). The routines return now -1 on error.
3628 o Tried to find all code that use buffer_format and buffer_unformat
3629 and added return value checking to prevent formatting and
3630 especially unformatting errors and possible subsequent fatal
3633 o Changed ske->x and ske->KEY to mallocated pointers in
3634 lib/silcske/silcske.h. Fixed possible data and memory leak.
3636 o Added return value checking to all *_parse* functions. Fixed
3637 many memory leaks as well.
3639 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3640 so that buffer overflows would not happen. All code now also
3641 checks the return value as it can fail.
3643 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Added reconnection support to server if the normal server looses
3646 its connection to the router (for example if router is rebooted).
3647 The server performs normal reconnection strategy implemented
3648 to the server. Affected file silcd/server.c.
3650 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added new packet type SILC_PACKET_SET_MODE that is used to
3653 distribute the information about changed modes (for clients,
3654 channels and clients channel modes) to all routers in the
3655 network. Updated the protocol specification accordingly.
3657 Added functions into silcd/packet_send.c and
3658 silcd/packet_receive.c: silc_server_send_set_mode,
3659 silc_server_set_mode.
3661 Added new files silcmode.[ch] into lib/silccore that implements
3662 the encoding and decoding of Set Mode Payload. Added new type
3663 SilcSetModePayload. Moved the definitions of different modes
3664 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3666 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Oops, a little mistake in server's connection authentication
3669 protocol. The protocol is not ended with FAILURE but with
3670 SUCCESS if the authentication is Ok. :) Affected file is
3673 * Implemented NICK_CHANGE notify handling in server in the file
3674 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3675 the local clients on the channel. After the changing nickname
3676 in router environment snhould work and the [<unknown>] nickname
3677 should appear no more.
3679 The silc_server_replace_id function that receives the Replace ID
3680 payload now sends the NICK_CHANGE notify type also in the file
3681 silcd/packet_receive.c
3683 * Changed WHOIS and IDENTIFY command to support the maximum amount
3684 of arguments defined in protocol specs (3328 arguments). This
3685 fixed a bug that caused problems when there were more than three
3688 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Added extra parameter, command identifier, to the
3691 silc_client_send_command so that explicit command identifier
3694 Changed that ID list routines uses specific command identifier
3695 when sending WHOIS/IDENTIFY requests to the server so that they
3696 can be identified when the reply comes back.
3698 Affected files lib/silcclient/command.[ch],
3699 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3701 * Added `sender' argument to silc_server_packet_send_to_channel
3702 to indicaet the sender who originally sent the packet to us
3703 that we are now re-sending. Ignored if NULL. Affected file
3704 silcd/packet_send.[ch].
3706 * Added some server statistics support in silcd/server_internal.h
3707 SilcServerStatistics structure and around the server code. Also
3708 send some nice statistics information when client is connecting
3711 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Fixed channel ID decoding in server's JOIN command reply in
3714 silcd/command_reply.c
3716 * Fixed braodcasting of replace ID payload to not to send it if
3717 we are standalone server in silcd/packet_receive.c.
3719 * Fixed all channel message sending routines to not to send
3720 packets to clients that has router set, since they are routed
3721 separately in the same function earlier. Affects file
3722 silcd/packet_send.c and all channel packet sending functions.
3724 * In USERS reply, res_argv[i] are not allocated, the table
3725 is allocated. Thus changed that free the table, not its
3728 * In server's whois_check and identify_check if the client is
3729 locally connected do not send any WHOIS commands - they are not
3732 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Fixed some minor bugs in client when sending WHOIS command. The
3735 arguments was in wrong order.
3737 * Removed statis function add_to_channel from server in
3738 silcd/command.c that was previously used with the joining but
3741 * Tested USERS command in router environment successfully with two
3742 routers, two servers and two clients.
3744 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Reorganized the USERS command and command reply in client library
3747 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3748 When the command is given by user we register a pending command
3749 callback that will reprocess the command after the reply has been
3750 received from the server. When reprocessing the packet we then
3751 display the information. Thus, the USERS information is displayed
3752 now in the command callback instead of in the command reply
3753 callback. The processing of the command is same as previously
3754 when server has sent the command reply in the JOINing process.
3756 * Added to USERS command in silcd/command_reply.c to join the client,
3757 we didn't use to know about, to the channel after we've created
3758 a client entry for it. Also, for clienet we did know already still
3759 check whether it is on the channel or not and add it if not.
3761 * Removed silc_server_command_join_notify as the function and its
3764 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Changed the client's pending command handling to the same as the
3767 server's pending command handling. It is also now possible to
3768 execute command reply functions from other command reply
3769 function as the function callbacks for commands and command
3770 replies are one and same. The pending commands are not static
3771 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3772 in client connection context. Thus, pending commands are server
3773 connection specific as it is convenient.
3775 Changed the function silc_client_command_pending and
3776 silc_client_command_pending_del and added new function
3777 silc_client_command_pending_check. Removed the
3778 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3781 * Added cmd_ident, current command identifier, to the client
3782 connection context in lib/silcclient/client.h to keep track on
3783 command identifiers used in command sending. Client's command reply
3784 function handling now supports the mandatory command identifiers.
3786 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3787 funtions in client to fully support pending command callbacks.
3789 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3790 as one of the arguments to the application in the command reply
3793 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3794 before first releasing SILC but came back. Now it is removed again
3795 and should come back nomore. The FORWARDED flag was used only
3796 by the JOINing procedure by forwarding the command packet to router.
3797 Now, the JOINing procedure has been changed to more generic (due
3798 to various router environment issues) and FORWARDED is not needed
3799 anymore for anything. The protocol specification is yet to be
3802 Now, removed silc_server_packet_forward from server and the flag
3803 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3805 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Renamed NAMES command to USERS command. The NAMES was named that
3808 due to historical reasons. Now it is renamed. Also, rewrote
3809 parts of the USERS command. The nickname list is not sent anymore
3810 by the server. Only Client ID and mode lists are sent in the USERS
3811 command. Changed this also to the protocol specification.
3813 The client now resolves the names and stuff after it receives
3814 the USERS list from the server when joining to the channel.
3816 * WHOIS and IDENTIFY commands has been changed to support multiple
3817 Client ID's per command. One can now search for multiple users
3818 in the network by sending only one WHOIS or IDENTIFY command.
3819 Changed the code and the protocol specifications.
3821 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3822 uses silc_server_command_whois_parse to parse the request. */
3824 * If normal server, do not parse the WHOIS and IDENTIFY requests
3825 before sending it to the router. Saves some time.
3827 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Fixed JOIN command on client library. Wrong number of arguments
3830 used to crash the client.
3832 * Added silc_server_channel_has_global function to check whether
3833 channel has global users or not.
3835 * Added silc_server_channel_has_local function to check whether channel
3836 has locally connected clients on the channel.
3838 * The silc_server_remove_from_one_channel now checks whether the
3839 channel has global users or not after given client was removed from
3840 the channel. It also checks whether the channel has local clients
3841 on the channel anymore. If it does not have then the channel entry
3842 is removed as it is not needed anymore.
3844 * The silc_server_notify now checks on JOIN notify whether the joining
3845 client is one of locally connected or global. If it is global then
3846 the channel has now global users on the channel and that is marked
3847 to the channel entry. Also, it now saves the global client to
3848 global list who is joining and JOINs it to the channel. This is
3849 for normal server, that is.
3851 Changed silc_server_send_notify_on_channel,
3852 silc_server_packet_relay_to_channel and
3853 silc_server_packet_send_to_channel check if we are normal server
3854 and client has router set (ie. global client) do not send the
3855 message to that client, as it is already routed to our router.
3857 * Implemented LEAVE notify type handling in silc_server_notify
3860 * Tested LEAVE command in router environment successfully. Tested
3861 with two routers, two servers and two clients.
3865 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3867 * Implemented SIGNOFF notify type handling in silc_server_notify
3870 * silc_server_remove_id now removes the client entry from all channels
3871 it has joined and thusly sends SIGNOFF notify type.
3873 * Rewrote the NAMES list generation in server by removing two excess
3874 loops. The lists are created now inside one loop.
3876 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * silc_server_remove_channel_user checks now also global list
3879 for channel and client.
3881 * silc_server_new_channel_user checks now both local and global
3882 list for channel and client. Fixed a bug in client id decoding.
3883 Used to decode wrong buffer.
3885 * silc_server_channel_message checks now both local and global
3886 list for channel entry.
3888 * Tested channel joining (hence JOIN) in router environment
3889 successfully. Tested with two routers, two servers and two
3892 * Tested channel message sending in router environment successfully.
3894 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Added silc_server_save_channel_key into server.[ch] to save the
3897 received channel key in Channel Key payload processing. It is
3898 also used in JOIN command reply handling.
3900 Equivalent function silc_client_save_channel_key added into
3901 client.[ch] into client library.
3903 * Changed JOIN command reply to send information whether the channel
3904 was created or not (is existing already) and the channel key
3905 payload. Changed protocol specs accordingly.
3907 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3908 the request was sent by ID and not by nickname. Crashed on
3911 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3914 now correctly save the received data.
3916 * silc_server_free_sock_user_data now notifies routers in the
3917 network about entities leaving the network.
3919 At the same time implemented functions silc_server_remove_id
3920 and silc_server_send_remove_id to receive and send REMOVE_ID
3921 packets. The packet is used to notify routers in the network
3922 about leaving entities. The ID removed will become invalid in
3925 * Added function silc_idlist_del_server into server. Removes and
3926 free's server entry from ID list.
3928 * silc_server_private_message function now checks, if we are router,
3929 that the destination ID really is valid ID, naturally.
3931 * In router when NEW_ID packet is received (for new client) the
3932 hash of the Client ID is saved in the ID Cache but the
3933 client->nickname is set to NULL, instead of putting the hash
3936 IDENTIFY command now also checks that client->nickname must be
3937 valid. If it is not if will request the data from the server who
3938 owns the client. Added new function
3939 silc_server_command_identify_check.
3941 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3942 to set the command to already allocated Command Payload.
3944 * Tested private message sending in router environment with two
3945 routers, two servers and two clients. Fixed minor bugs and now
3948 * Fixed segfault from client's NAMES command. Used to crash if
3951 * Forwarded packets must not be routed even if it is not destined
3952 to the receiver. Changed server code comply with this.
3954 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added `require_reverse_mapping' boolean value to ServerParams
3957 structure. If TRUE (not default) the server will require that
3958 the connecting host has fully qualified domain name.
3960 If the reverse mapping is not required and hostname could not be
3961 found the IP address is used as hostname.
3963 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Implemented version string checking to both client and server.
3966 The check is incomplete currently due to the abnormal version
3967 strings used in development version of SILC.
3969 * Changed all command functions in server to use the new
3972 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Changed char *data to unsigned char *data in ID Cache system to
3975 support binary data as ID Cache data. Changed code to support
3976 binary data in lib/silccore/idcache.c.
3978 * Renamed silc_server_packet_relay_command_reply to
3979 silc_server_command_reply as it is normal packet receiving
3980 function. Rewrote the function to accept command replys for
3981 servers and not only for clients.
3983 * Mark remote router always as registered server if we are connecting
3984 to it. Otherwise, commands sent by the router to us are ignored.
3986 * All ID List find routines now returns the ID Cache Entry pointer
3987 as well if requested.
3989 * WHOIS command works now in router environment, tested with two
3990 routers, two servers and two clients.
3992 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3993 in router environment (as it is almost equivalent to WHOIS) but
3994 hasn't been tested thoroughly. Added new functions:
3996 silc_server_command_identify_parse
3997 silc_server_command_identify_send_reply
3998 silc_server_command_identify_from_client
3999 silc_server_command_identify_from_server
4001 * Disabled route cache adding because adding two different ID's with
4002 same IP replaces the old cache entry thus giving wrong route.
4003 The entry->router->connection is always the fastest route anyway
4004 so route cache may not be needed. Of course, new routes maybe
4005 established after receiving the ID when the entry->router->connection
4006 might not be anymore the most optimal.
4008 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Add route cache for received ID for fast routing.
4012 * Added silc_server_packet_route to route received packet on router
4013 that is not destined to us.
4015 * Renamed silc_server_get_route to silc_server_route_get.
4017 * Added id_string and id_string_len fields into SilcServer to
4018 include encoded ServerID for fast comparing without excess
4019 encoding of the ID's.
4021 * Cleaned up WHOIS command on server side. Added following static
4024 silc_server_command_whois_parse
4025 silc_server_command_whois_check
4026 silc_server_command_whois_send_reply
4027 silc_server_command_whois_from_client
4028 silc_server_command_whois_from_server
4030 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4031 arguments in command replies. All command functions should be
4032 updated to use this macro.
4034 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Minor typo fixes on command reply handling on server.
4038 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Added silc_server_command_add_to_channel internal routine to add
4041 the client to the channel after router has created the channel and
4042 sent command reply to the server.
4044 * Added generic silc_server_send_command to send any command from
4047 * Use static buffer with ID rendering instead of duplicating data.
4049 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Fixed a channel user mode bug when joining to a channel server gave
4052 everybody channel founder rights, oops.
4054 * We mark ourselves as the router of the incoming server connection
4055 if we are router ourselves. This way we can check in some packet
4056 sending functions whether it is locally connected server. For
4057 incoming router connections we put NULL.
4059 * For router sending packets locally means now always sending the
4060 packet cell wide; to local clients and local servers. For normal
4061 server sending packet locally means sending it to only local
4064 * Fixed the JOIN command to really work in router environment. If the
4065 channel is created it is always created by the router. Router is
4066 also responsible of making the initial joining to the channel,
4067 sending JOIN notify to the sending server and distributing
4068 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4069 does not exist server doesn't do anything else but forward the
4070 command to the router which performs everything.
4072 * Added silc_server_send_channel_key function to send the Channel Key
4075 * Added silc_server_create_channel_key to create new channel key. The
4076 channel key is now re-generated everytime someone joins or leaves
4077 a channel, as protocol dictates. Note: channel->key_len is the
4080 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4083 packet_receive.[ch] to separate packet sending and receiving
4084 routines. The server.[ch] now includes everything else including
4085 actual packet processing (writing and reading data) and other
4088 Renamed silc_server_private_message_send_internal to
4089 silc_server_send_private_message. The routine is still though
4090 used only to relay private messages as server does not send
4091 private messages itself.
4093 Renamed silc_server_new_channel to silc_server_create_new_channel
4094 and added new function sicl_server_new_channel that handles the
4095 incoming New Channel packet. Added also new sending function
4096 silc_server_send_new_channel to send New Channel Payload.
4098 * Added new function silc_server_notify to process incoming notify
4099 packet to the server/router. Server may then relay the notify
4100 to clients if needed.
4102 * Added new function silc_server_new_channel_user to process incoming
4103 New Channel User packet. Router will redistribute the packet and
4104 send JOIN notify to its local clients and locally connected servers
4105 if needed. Normal server will send JOIN notify to its local client
4106 on same channel when received this packet. Added also corresponding
4107 sending function silc_server_send_new_channel_user to sent the
4110 * Added boolean route argument to send_notif_to_channel and
4111 packet_send_to_channel functions to attempt to route the packet
4112 if it is TRUE and send only locally if it is FALSE.
4114 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * silc_server_replace_id now broadcasts the received replace ID
4117 packet if it is not broadcast packet already. The router must
4118 broadcast to inform other routers about changed ID.
4120 * Added backpointer to server's router into SilcServer context in
4121 silcd/server_internal.h.
4123 * Fixed silc_server_packet_broadcast to send correct broadcast
4126 * The channel key is now distributed to the local client as soon
4127 as it is received from the router (in router environment) so that
4128 no other packet may be sent for the channel until client has
4131 * silc_server_remove_channel_user now broadcasts the received
4132 Remove Channel User packet if it is not broadcast packet already.
4133 The router must broadcast to inform other routers about removed
4136 * Added users field into SilcPacketContext that is a reference count
4137 of the context. One can increase the reference count by calling
4138 silc_packet_context_dup which is now changed to just increase the
4139 reference count instead of duplicating the data. The reference
4140 count is decresed by calling silc_packet_context_free that will
4141 free the data after the reference count hits zero.
4143 For now on the packet context and everything allocated into it
4144 (including the raw packet from network) must be freed by calling
4145 the new silc_packet_context_free function. Added also new function
4146 silc_packet_context_alloc that must be used now to allocate the
4147 context. This also means that if a routine is asynchronous from
4148 silc_[client/server]_packet_parse_type the packet context must
4149 be duplicated by calling silc_packet_context_dup. Otherwise it
4150 gets free'd after silc_[client/server]_packet_parse_type returns.
4151 Also, one must remember that if packet is duplicated then its
4152 reference count must be decresed by calling the free function as
4153 many times as it was duplicated.
4155 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4156 from both client and server.
4158 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Made joining to a channel working in router environment.
4162 * Cleaned up JOIN command on server side and create function
4163 silc_server_command_join_channel internal routine to make the
4166 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Changed silc_command_pending list to SilcDList. Also, added
4169 `ident' field to SilcServerCommandPending structure to identify
4170 the reply and to call correct callback.
4172 Added silc_server_command_pending_check function to replace the
4173 corresnponding macro. The silc_command_pending list is not
4176 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4177 to set identifier to previously allocated Command Payload. It
4178 is used to set identifier for command when resending Command
4181 * Added silc_command_payload_encode_payload to encode Command
4182 Payload buffer from SilcCommandPayload structure.
4184 * Added silc_argument_payload_encode_payload to encode Argument
4185 payload buffer from SilcArgumentPayload structure.
4187 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Changed WHOIS command to support router connection on server side.
4190 The whois request is always sent to router unless the server is
4191 standalone server. After server has received the reply from the
4192 router will it send the reply to the client.
4194 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4195 broadcast received broadcast packet. The function is used only
4196 by router. The broadcast packet is always sent to the router's
4199 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4200 render given ID to printable string, for log files for example.
4202 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Made basic router to router connections working. At least they
4205 can now connect to each other but nothing really works the way
4206 they are supposed - yet.
4208 * Added new initiator token to RouterConnection configuration
4209 file in silcd/serverconfig.[ch]. It is used to tell whether we
4210 are the initiator to the remote router or whether we'll expect
4211 the other end to connect.
4213 * Moved registering of listener task to silc_server_init, hence
4214 the server starts listenning as soon as it is run, even if it
4215 does not have connections to other routers. Let's see how well
4218 * Changed default connection retry timeouts for more suitable in
4221 * Removed cipher and such arguments from silc_idlist_add_client
4222 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4223 Added new function silc_idlist_add_data to add the keys and stuff
4226 * Added SilcIDListData structure and added it to SilcClientEntry
4227 and SilcServerEntry as their first field in the structure. This
4228 way we can explicitly cast the ID entries to the SilcIDListData
4229 structure and get common data for the entries. In past, we had
4230 to first check what type of connection it is and then cast it to
4231 correct ID entry type. Now, we can directly cast the opaque
4232 pointer to the SilcIDListData (no matter what ID entry it actually
4233 is) and get the data needed.
4235 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4238 in some circumstances even if threre were timeout tasks, though not
4239 IO tasks, but tasks anyway. Now fixed.
4241 * Defined SilcServerConnection structure to hold connection specific
4242 stuff about directly connected servers and routers. The definition
4243 is currently in silcd/server_internal.h. I thought about having
4244 a bit more important role fro this struct but for now it is used
4245 only when connecting to other server (or router actually).
4247 * Added connecting retry support in server when connecting to
4248 router(s). The retry feature implement exponential backoff
4249 algorithm. Also, added SilcServerParams structure to hold default
4250 parameters for server. For now, it include these retry settings
4251 and are hard coded. After server is moded to be as Silc Server
4252 Library this structure will be more important.
4254 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Changed client librarys channel->clients table to SilcList and
4257 changed code accordingly.
4259 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Changed client's channel table to SilcList and changed code
4262 accordingly. Also changed SilcChannelClientEntry to include back-
4263 pointer to the channel so that client entry can use that structure
4264 as list as well and we have fast cross-reference to the channel.
4265 This change dramatically decreased the complexity of channel
4266 handling with client entry and vice versa (removed one extra
4267 loop when searching for channel entry from many functions).
4269 * Changed server->sim from table to SilcDList and changed code
4272 * NAMES command can now be used from user interface. It will show
4273 the user list on the channel, neatly.
4275 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4276 Code now saves realname of the user if it becomes available.
4278 * Renamed configure.in to configure.in.pre and made ./prepare
4279 script to automatically add correct version string to
4280 configure.in which it creates from configure.in.pre.
4282 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * NAMES command reply now shows users mode with the nickname when
4287 * Moved silc_client_ch[u]mode[_char] functions from
4288 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4289 place sucks, they are utility functions and should be in some
4292 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4294 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4297 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Added TRQ (efficient deque and list library) into lib/trq. This is
4302 a very good list library that is currently used in the SILC. Defined
4303 SilcList API over the library because I didn't like the API very
4304 much. See lib/trq/silclist.h for the API and examples of how to
4305 use the API. Fixed various places in the code to use the new
4306 SilcList API. The SilcList is meant for lists that has a structure
4307 already defined as a list. It is not suitable to add just some
4308 context to the list (in TRQ, the context is the list actually).
4310 So, I defined SilcDList that can be used for the purpose where
4311 predefined list structure does not exit. This can be used as
4312 such list. Now some context just can be added to the SilcDList.
4313 Currently this list is not used in the SILC just yet, though there
4314 are a lot places where this can replace dynamically allocated
4315 tables and I will fix these places, later, to use SilcDList.
4316 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4317 and use TRQ internally).
4319 Also fixed some annoying warning messages that the original TRQ
4320 code generated. Also minor changes to TRQ's Makefile.in.
4322 * Added support for querying by Client ID to both WHOIS and
4323 IDENTIFY commands into server, as required by the protocol.
4325 * Removed method function pointers from SilcBuffer structure. They
4326 weren't used to anything and just increased the context size for
4327 no good reason. This change also made silc_buffer_alloc and
4328 silc_buffer_free functions inline functions.
4330 * Disabled command flooding detection support until it's fixed so
4331 that it accepts commands in but does not execute them more than once
4334 * Added silc_net_localhost(), to return local hostname, into
4335 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4336 that must be initialized before calling silc_client_init.
4338 * Added new function: silc_server_send_notify_on_channels to send
4339 notify messages to all channels client has joined. It is assured
4340 that the message is sent only once per client.
4342 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4343 lib/silcutil/silcutil.[ch] as silc_format function. The new
4344 function is generic and is used by server as well, not only by
4345 the logging routines.
4347 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4348 the provided version string was not acceptable. Added new function:
4349 silc_ske_check_version into lib/silcske/silcske.h. The function
4350 must be implemented by the application (client or server) and it
4351 does not reside in the SKE library. The function checks the version
4352 string remote end sent.
4354 * Added back pointers (to opaque context and to SilcSocketConnection)
4355 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4357 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4358 duplicate packet context structure.
4360 * Changed `notify' client operation to send same arguments as client
4361 receives from server except for ID's. ID's are mapped to correct
4362 ID entry and that is returned. Also, if channel entry is not sent
4363 by server but the notify is for channel the channel entry is sent
4364 to application (otherwise application doesn't know that it is for
4365 channel (library gets it from packet's Destination ID)).
4367 * Added silc_client_remove_from_channels into client library to
4368 remove a client from all channels it has joined to. Used when
4369 received SIGNOFF notify from server. Added also new function
4370 silc_client_replace_from_channels to replace old ID entry with
4371 new ID entry on all channels. Used when received NICK_CHANGE
4374 * Fixed ID Cache list handling in silc_idlist_get_client in
4375 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4376 to get (or query) client by ID.
4378 * Updated TODO list.
4380 * Added connection authentication status message defined by the
4381 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4382 support for these into the code in client and server side.
4384 * Added generic function silc_client_send_command to send any command
4385 with variable argument list. Application should use this function
4386 to send commands if the command functions provided by the library
4387 does not suite for the application's user interface needs.
4389 * Added new `failure' client operation. Application is notified about
4390 received failure packet if client is executing a protocol. In this
4391 case the protocol's execution has failed.
4393 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4394 is required by the protocol.
4396 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4397 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4400 * Added status flag to SilcSKE object to indicate realtime status
4401 of the SKE protocol.
4403 * Application receives now exactly same command reply arguments as
4404 the library receives from server. However, if ID is received the
4405 corresponding ID entry is returned to the application (eg. Client
4406 ID is mapped to correct SilcClientEntry entry and that is returned).
4407 Changed command_reply client operation due to this change.
4409 * Changed all ID's in commands and in command replys as ID Payloads.
4410 Change affected both client and server side codes.
4412 All ID's sent in SILC network (with execption of ID's in SILC
4413 Packet header) are sent in ID Payload to support variable length
4416 * Server now notifies nick changes and notifies all clients on
4417 the channels about the new nickname (about the new Client ID,
4420 * Implemented CMODE command to change channel modes. Supports all
4421 channel modes defined by the protocol specs except ban and invite
4422 lists. (Also, private channel key mode is supported but support for
4423 setting private channel key in client is missing, thus, this mode
4424 has no effect on client side (except that server requires that the
4425 client uses private channel key and normal channel traffic does not
4428 Also, invite mode works per se, but INVITE command does not work
4429 yet correctly, so you can set channel as invite only channel but
4430 inviting clients to the channel does not work (it is yet to be
4431 thought what's the best way to do it).
4433 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4434 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4435 Implemented CUMODE command to change user's mode on the channel.
4436 Supports all modes defined by the protocol specs.
4438 * Added NAMES command reply to return users modes on the channel.
4440 * Removed unnecessary and slow ciphers from lib/silccrypt.
4442 * Set SO_KEEPALIVE option to connection sockets by default.
4444 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4446 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4447 redefined the Notify Payload into protocol specs.
4449 * Added silc_id_payload_parse_id to get ID directly from raw
4452 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4455 accept searching by Client ID as well.
4457 * Added support for LEAVE and SIGNOFF notify types in client library.
4459 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4460 to parse ID Payload from raw data.
4462 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added flags parameter into silc_ske_assemble_security_properties
4465 function in lib/silcske/silcske.[ch].
4467 * Changed notify client operation to fit better for notify messages
4468 sent by server. The notify payload received from server is now
4469 passed to the application (after parsing it to SilcNotifyPayload).
4470 It is application's responsibility to retrieve the arguments
4471 from the payload and show the message the way it wants. The message
4472 sent by server is implementation specific.
4474 * Changed public keys to comply with the protocol specification.
4475 Old public keys are not supported anymore and are not compatible.
4477 * Removed nickname from Channel Payload as the latest draft removed
4478 it. The client must resolve the nickname from the NAMES command
4479 reply received when it joined the channel.
4481 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4483 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Fixed some errors in protocol specification drafts.
4487 * Created lib/silccore/silcnotify.c to implement Notify Payload
4488 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4489 generic payloads described by protocol specifications. The file
4490 includes implementations for ID Payload and Argument Payload.
4492 * Changed Command Payload implementation to use the new Argument
4493 Payload. Changed command_xxxx_payload to command_payload_xxxx
4494 to comply with SILC coding conventions.
4496 * Added suppport for Argument Payload handling in Notify Payload
4497 implementation as protocol requires it. Added the new support
4498 into server and client lib as well.
4500 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Added support for multiple nicknames on same channel. [n] is
4503 added locally to the nickname if there are more than one same
4504 nicknames on the channel.
4506 * Server now sends all nicknames that matched WHOIS request.
4507 Client also shows the list received from server.
4509 * Added TOPIC command to client side. User can now set and show
4510 current topic on channel.
4512 * Added MOTD command to client and server. Also, server sends the
4513 motd when client connects to the server.
4515 * Changed version strings to comply ISO 8601.
4517 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Fixed protocol error handling in client library. It should now
4520 cope even if the SKE fails for some reason.
4522 * Made new protocol specification drafts for submitting to IETF.
4524 * Implemented TOPIC command to server in silcd/command.c.
4526 * Added two new notify types into lib/silccore/silcnotify.h:
4527 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4528 notify nickname change and topic setting/change on a channel.
4530 * API change of command_reply operation in client library. The
4531 application gets now the status type received from server as well.
4533 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4537 * Cras fixed and optimized the packet handling even further and
4538 it should work now. Minor change to the prototype of function
4539 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4541 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Added new function into lib/silcutil/silcschedule.[ch]:
4544 silc_schedule_with_fd to select() a specified fd. The function
4545 returns after timeout expires or data arrives or goes. The
4546 function is used by packet routines to wait that all data is
4547 received from network.
4549 * Fixed data reading from network in lib/silccore/silcpacket.c.
4550 The code now assures that all data is read from the fd and then
4551 continues packet processing. This was a bug fix since the code
4552 used to drop some data in some circumstances.
4554 * Added new function into lib/silcclient/client.[ch]:
4555 silc_client_start_key_exchange to start key exchange after
4556 connection has been established to server. The code internally
4557 now uses this funtion but its main purpose was to provide it
4558 for applications that perform their own connecting. After
4559 application has created a connection it merely calls this
4560 function to start the key exchange between client and server.
4561 The library takes care of everything else after that.
4563 Updated also lib/silcclient/README to explain the usage of
4566 * Do not send to application information that connection has
4567 been established. Application gets notified it by connect
4570 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Applied cras's patch to add silc_schedule_one function. The
4573 function runs scheduler once and returns.
4575 * Fixed the scheduler after cras messed it up. The timeout
4576 handling works now as it's supposed to work.
4578 * Added into lib/silccore/ silcnotify.h to include notify
4579 message types support. Changed silc_server_send_notify*
4580 functions, in server.[ch], to support those new notify types.
4581 Added the support for the notify types into client library,
4582 as well. Added new notify client operation into ops.h in
4585 * Changed silc_server_packet_send_to_channel to send normal
4586 packets instead of just channel message packets. The function
4587 is now used to send the notify packets to channels. It is not
4588 used to send channel message packets anymore, as server never
4591 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4592 va_arg()s as it seems to require it nowadays. I guess, if SILC
4593 is compiled with older va_arg() the new code should work anyway.
4595 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Splitted core library. Core library (lib/silccore) includes
4598 now only SILC protocol specific core (and common) components.
4599 Created new utility library (lib/silcutil) that includes more
4600 generic purpose stuff. The stuff for util library was taken
4601 from the old core library. This was minor and easy split.
4603 * Created SILC Client Library (lib/silcclient) that includes
4604 implementation of the SILC client without user interface. This
4605 was major move from silc/ directory. The code has been changed
4606 so that it is transparent towards the user interface. The
4607 silc/ directory includes now the same user interface as before
4608 and it uses the new client library. Read lib/silcclient/README.
4609 Basicly, the client library performs everything else related
4610 to SILC except user interface handling. Also, configuration
4611 files are considered to be part of user interface and library
4612 does not handle them.
4614 This change also changed a lot of structures, function naming etc.
4615 Most important change was that SilcClientWindow object was
4616 renamed to SilcClientConnection in the client library. Created
4617 also new file lib/silcclient/ops.h. Also added new files
4618 silc/local_command.[ch] and silc/client_ops.[ch].
4620 All these changes were made to make it easier for user interface
4621 designers to create what ever user interface for the SILC client
4624 It is also expected that the server will be moved to lib
4625 directory as well and SILC Server Library will be created;
4626 sometimes in the future.
4628 * Removed Local commands from lib/silccore/silccommand.h as
4629 they are application specific and new client library does not
4630 handle any of those anymore.
4632 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4633 old client implementation in silc/.
4635 * Added support for callback functions in SILC_LOG_* macros.
4636 Application can now set its own callbacks that will be called
4637 instead of using the default functions that will always print
4638 the debug messages to stderr (or stdout). Also, debugging can
4639 now be disabled by setting silc_debug to FALSE and re-enabled by
4640 setting it to TRUE. Note, that logging will still work even
4641 if debugging is disabled.
4643 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4644 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4645 silc_log_reset_debug_callbacks.
4647 * To enable debugging in silc client one must give now -d
4648 option on command line.
4650 * Changed silc_schedule_init to automatically allocate task queues
4651 if they are not allocated before calling it.
4653 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Added GMP 3.1 into math library.
4657 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4660 a channel in SILC network. The packet is used by servers and
4661 routers to notify other routers that user has left a channel.
4662 This little feature was missing until now. Added the feature
4663 to protocol specification as well.
4665 Added functions: silc_server_send_remove_channel_user and
4666 silc_server_remove_channel_user into server.[ch].
4668 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4669 lib/silccore/silcpacket.h. However, they are not implemented
4672 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Fixed joining to a channel and sending channel messages
4675 between server and router. The channel message sending should
4676 now work inside a cell.
4678 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Fixed the private message sending between server and router.
4681 The private message sending should now work inside a cell.
4683 * Added silc_server_replace_id into server.[ch] to replace
4684 existing ID in the SILC network.
4686 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4687 and silc_idlist_replace_server_id into idlist.[ch] in server.
4689 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Fixed the server to server connections. Server can again now
4692 connect to router. Router to router connections probably does
4695 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added dynamic protocol registering support. Now protocols can
4698 registered and unregistered on the fly. Patch by cras.
4700 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Added lib/contrib directory to hold routines that some platforms
4703 don't have but are needed by SILC.
4705 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4706 into lin/contrib to provide getopt() and getopt_long() for
4707 those who don't have it.
4709 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Added AWAY command to client. When away message is set and
4712 client receives a private message packet the client automatically
4713 replies to the sender with the away message.
4715 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4716 bug seemed to be the cause of recent problems when compiling
4719 * Added version detection support to SKE protocol specification
4720 and added the new changes to the SKE implementation as well.
4721 There were other minor changes in the SKE protocol as well.
4723 Many changes in lib/silcske/silcske.[ch] and in
4724 lib/silcske/payload.[ch].
4726 * Added ^U functionality, clear input line. Patch from cras.
4728 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Mainly small bugfixes on core library. Fixed some debugging
4731 logging and buffer overflow in silclog.c.
4733 * Updated config.sub and config.guess on the distribution tree.
4735 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Added command lagging support in server. Client may execute
4738 commands now only once in two seconds.
4740 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Optimized packet reception. MAC computation and checking is now
4743 also more optimized. A lot previously duplicated code is now
4744 used as generic by both client and server.
4746 * Fixed key pair generation in clientutil.c
4748 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Added into lib/silccore/silcbufutil.[ch] new function;
4751 silc_buffer_realloc.
4753 * Moved generic packet sending/encryption functions to
4754 lib/silccore/silcpacket.[ch] from client and server. Some
4755 rewriting of the functions.
4757 * Moved all generic packet reception/decryption functions to
4758 lib/silccore/silcpacket.[ch] from client and server. The
4759 packet processing is now much cleaner in both client and server.
4760 These were major changes in both client and server.
4762 * Created many common functions in server to do packet sending.
4763 Previously code were duplicated a lot, this has been removed
4766 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Rewrote major parts of the ID cache system. Don't know
4769 whether it is better now or not but at least the API is more
4772 * Major rewrite on ID cache stuff on client because of the ID
4773 cache API changes. Added idlist.c to client.
4775 * Also major rewrite on ID cache stuff on server as well.
4776 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4777 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4778 in hand, instead they are all put into the ID cache system now.
4779 All server_idlist_* routines uses ID cache now instead of
4780 traversing its own lists (those lists does not exist anymore).
4781 SilcIDList though still exists. Also, SilcXXXEntry's are
4784 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Finally made the SKE implementation compliant to the protocol
4787 specification. All mp integers are now binary encoded as
4788 opposed being HEX encoded.
4790 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4793 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4794 functions: silc_[encode/decode]_pem. Also added function
4795 silc_encode_pem_file to PEM encode with newlines ('\n') for
4798 * SILC public keys are now encoded either PEM or binary. Same
4799 option is for private keys as well. By default private keys
4800 are binary encoded and public keys PEM encoded. Silly HEX
4801 encoding were removed.
4803 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4804 function to create fingerprints.
4806 * Fixed a bug in SHA1; does not change the original data anymore.
4808 * Partly implemented INFO command on client and server side.
4809 Fixed CLEAR command. Changes to SERVER command; show current
4810 server(s) when giving command without arguments. Added
4811 VERSION command to client.
4813 * Added check to server that unregistered connections cannot
4814 execute commands (unless it is specificly allowed).
4816 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4818 * Fixed screen refresh.
4820 * Fixed channel joining bug from client. On some circumstances
4821 client tried to join to a channel it had already joined.
4823 * Added public key verification process into client's protocol.c.
4824 The client now verifies the public key from user and saves
4825 it into ~./silc/serverkeys/ directory.
4827 Added into: clientutil.[ch]: silc_client_verify_server_key.
4829 * Changed SKE protocol's silc_ske_initiator_finish function
4830 to accept callback function that verifies the received public
4831 key. Removed old silc_ske_verify_public_key function.
4833 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4835 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4836 silc_pkcs_private_key[_data]_set.
4838 * Made the password and public authentication more cleaner in
4839 server's protocol.c.
4841 * Removed historic and obsolete protocol `channel_auth' from
4842 both client and server.
4844 * Removed wrong way of sending command status messages from
4845 server to client in server's command.c. The old way violated
4846 protocol specification.
4848 Changes to silccore/silccommand.[ch]: removed
4849 silc_command_encode_status_payload -> not needed anymore,
4850 changed silc_command_encode_payload_va to accept extra
4851 argument on variable argument list. The argument type must
4852 now be provided to the function. Also, added new function:
4853 silc_command_encode_reply_payload_va which is same as
4854 normal command_encode_payload_va except command status type
4855 is provided as extra argument.
4857 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Added ~./silc directory handling. The directory includes the
4860 public and private keys for the client.
4862 Added silc_client_check_silc_dir, silc_client_create_identifier
4863 and silc_client_load_keys.
4865 * Implemented SILC protocol compliant public key. Added public
4866 and private key saving to and loading from files.
4868 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4869 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4870 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4871 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4872 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4874 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4875 silc_pkcs_load_[public/private]_key.
4877 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added silc_server_get_route (route.[ch]) to get connection
4880 data for the fastest route for given ID.
4882 * Implemented INVITE command on client and server. The command
4883 were re-defined in the SILC Protocol Specification and the
4884 implementation now complies with the specification.
4886 * Implemented PING command on client and server.
4888 * Implemented NAMES command on client and server. The server side
4889 supports currently only normal server not router server yet.
4890 Some changes to NAMES definition in SILC protocol specification.
4892 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Implemented LEAVE command on client and server.
4896 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4897 again. This change was made to the protocol as well. Server
4898 should not violate the protocol specification anymore.
4900 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4903 was tested. SOCKS4 was not but should work anyway.
