1 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added the SILC Document generator to the scripts/silcdoc.
4 It can be used to generate the Toolkit Reference Manual out
5 of the source tree. Internally it will also use the RoboDoc
6 generator now imported in util/robodoc.
8 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Added couple of return's in rekey protocol if error orccurred
11 during the protocol. The execution must be terminated.
12 Affected file silcd/protocol.c. Also, terminate the protocol
15 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
17 * The client's Client ID was created initally from the wrong
18 nickname (it could have been in format nick@host) in the
19 silc_server_new_client. Affected file silcd/packet_receive.c
21 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

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

65 * Do not add TCP_NODELAY flag if the operating system
66 does not have it defined. Affected files are
67 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
69 * Fixed buffer overflow from Irssi SILC Client. Affected
70 file irssi/src/fe-common/core/themes.c.
72 * Fixed double free in client library in the file
73 lib/silcclient/client.c when disconnecting from server.
75 * Applied double free patch from cras to Irssi SILC client.
76 Affected files irssi/src/core/[modules/expandos].c
78 * Fixed the disconnection handling to Irssi SILC Client.
79 The application must call silc_client_close_connection
80 in ops->connect client operation in case of failure of
81 the connection. Affected file is
82 irssi/src/silc/core/client_ops.c.
84 * Do not set sock->protocol to NULL in the function
85 silc_client_close_connection after executing the protocol's
86 final callback since the sock might not be valid anymore.
87 Affected file lib/silcclient/client.c.
89 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
91 * Do not enable SILC_THREADS if the linking with libpthread
92 did not happen. Affected file configure.in.pre.
94 * Added notion to protocol specification that server must
95 verify the sent authentication payload with CMODE when
96 setting the channel founder key. Implemented it to the
97 server. Affected file silcd/command.c.
99 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
101 * Added _EXTRA_DIST SILC distribution variable to the
102 distributions file. It is used to conditionally add extra
103 files or directories to the specific distribution. Affected
104 files ./prepare, Makefile.am.pre and distributions.
106 Removed the `_' from the start of the distribution names.
109 * Added README.WIN32 for instructions to compile the Toolkit
112 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
114 * Fixed a double free in disconnection in the server. Affected
115 file is silcd/server.c.
117 * Fixed the lib/silcske/groups.c to work now also with GMP
118 MP library. The string conversion did not work when using
119 specific base and the base is indicated in the string as well.
121 * Created win32/ directory which now includes MSVC++ specific
122 stuff so that toolkit (DLLs) may be compiled with MSVC++.
123 It will appear only in the toolkit distribution
125 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
127 * Changed the key material distribution function in case when
128 the hash output is too short. The data is now concatenated
129 a bit differently than it used to. Made the change to the
130 SKE protocol specification.
132 * Added better GMP detection to configure.in.pre. A patch
135 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Fixed a minor bug in SKE that might cause some problem on
138 some platforms. Affected file lib/silcske/silcske.c.
140 * Added the cookie checking for initiator in the SKE. It checks
141 that the responder returns the sent cookie unmodified. The
142 affected file is lib/silcske/silcske.c. Added new SKE
143 error type INVALID_COOKIE that can be sent during the
144 negotiation. Fixed some memory leaks as well.
146 * Added the "invalid cookie" error message to Irssi SILC client's
149 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
151 * Added `task_max' field to the SilcClientParams to indicate
152 the maximum tasks the scheduler can handle. If set to zero,
153 default values are used. Affected file lib/silcclient/silcapi.h.
155 * Fixed memory leaks in silc_client_close_connection. Affected
156 file lib/silcclient/client.c.
158 * Added silc_client_del_client_entry to client library to free
159 all memory of given client entry. Affected file is
160 lib/silcclient/idlist.[ch].
162 * Added new functions silc_client_del_channel and
163 silc_client_del_server to delete channel and server entries.
164 Affected file lib/silcclient/[silcapi.h/idlist.c].
166 * Removed silc_client_del_client_by_id from silcapi.h.
168 * Fixed the INFO command to return the server's own info
169 correctly when querying by Server ID. Affected file is
172 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
174 * Removed the non-blocking settings in WIN32 code in the
175 silc_sock_[read/write] and added SleepEx instead. Affected
176 file lib/silcutil/win32/silcwin32sockconn.c. The availability
177 of input data is now checked with FIONREAD and ioctlsocket.
179 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
181 * Call silc_schedule_task_del_by_context in the
182 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
183 Affected file lib/silccore/silcprotocol.c.
185 * Call silc_protocol_cancel for active protocols in the
186 silc_server_close_connection if the funtion
187 silc_server_free_sock_user_data has not been called.
188 Affected file silcd/server.c.
190 * Generic tasks cannot be deleted using the del_by_fd
191 task deleting function since generic tasks does not match
192 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
194 * Added a notion to SILCOPER help file that the SILCOPER works
195 only on router server, not on normal server.
197 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
199 * Added for WIN32 support for the new scheduler as well.
200 Affected file lib/silcutil/win32/silcwin32schedule.c.
202 * Fixed the SHA1 implementation to work on various platforms.
204 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
206 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
207 API. It is part of the scheduler now. Everything else is
208 as previously but some functions has changed their names.
209 Checkout the lib/silcutil/silcschedule.h for the interface.
210 Updated all applications to use the new interface. Affected
211 files are lib/silcutil/silcschedule.[ch].
213 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
215 * Found a bug in the SKE implementation. The HASH value,
216 specified by the protocol, was not computed correctly. The
217 public key of the responder was not added to the computation
218 even though it is mandatory. Affected file lib/silcske/silcske.c.
219 This unfortunately causes incompatibilities with older
222 * Added WIN32 specific network init and uninit functions:
223 silc_net_win32_init and silc_net_win32_uninit to init and uninit
224 the Winsock2. Affected file lib/silcutil/silcnet.h and
225 lib/silcutil/win32/silcwin32net.c.
227 * Set the socket always to nonblocking mode on WIN32 after
228 reading data or writing data. Affected file is
229 lib/silcutil/win32/silcwin32sockconn.c.
231 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
233 * Fixed various compilation problems under WIN32. Affected
234 files lib/silcutil/win32/silcwin32thread.c and
235 lib/silcutil/win32/silcwin32schedule.c.
237 * Removed all _internal.h #includes from public header
238 files. Internal headers must never be included from
241 Removed also the lib/silcske/payload_internal.h file.
243 * All include files that may be needed (public and some others
244 included by the public headers) by application developers are
245 now copied to the ./includes directory. It does not copy any
246 internal headers. Affected file Makefile.defines.pre and all
247 Makefile.am's under lib/ and subdirs.
249 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
251 * Do not change the ~/.silc directory's permissions automatically.
252 Affected file irssi/src/silc/core/clientutil.c.
254 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
256 * Do not cancel the protocol in silc_server_close_connection
257 it might cause recursion. Now cancelled in the function
258 silc_server_free_sock_user_data. Affected file silcd/server.c.
260 * Fixed the silc_server_remove_clients_by_server to regenerate
261 the channel keys correctly finally. Added also new function
262 silc_server_remove_clients_channels to actually do it.
263 Affected file silcd/server.c.
265 * Fixed the silc_server_new_channel to not crash by giving
266 wrong router to the new channel. Affected file is
267 silcd/packet_receive.c.
269 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
271 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
272 which is given as argument to the silc_client_alloc now.
273 It can be used to configure the client and set various parameters
274 that affect the function of the client.
276 * The USERS command in server did not check whether the channel
277 is private or secret. Affected file silcd/command.c.
279 * Added new argument to the USERS command in protocol specification.
280 The USERS command now can take the channel name as argument
281 as well. Added support for this in client and server and
282 updated the protocol specs.
284 * Completed the GETKEY command in client. It can be now used
285 to fetch also servers public key not only some clients.
286 Affected files lib/silcclient/command[_reply].c.
288 * Added silc_client_get_server to return server entry by the
289 server name. Affected files lib/silcclient/silcapi.h and
292 * Redefined the IDENTIFY command in protocol specification to be
293 more generic. It now can be used to query information about
294 any entity in the SILC Network, including clients, servers and
295 channels. The query may be based either the entity's name
296 or the ID. Added support for this in both client and server.
298 Affected files silcd/command.c and lib/silcclient/command.c
301 * Optimized the WHOIS and WHOWAS commands in the server. Removed
302 the _from_client and _from_server functions. Affected file
305 * Added silc_client_get_channel_by_id_resolve to the file
306 lib/silcclient/silcapi.h to resolve channel information by
307 its ID. Added also silc_client_get_channel_by_id that
308 does not resolve it from the server.
310 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Added SilcServerEntry context into the client library
313 to represent one server. The INFO command now allocates
314 these to save the resolved server info. For now on the
315 client library will also keep information about servers,
316 connected and resolved with INFO.
318 The INFO command now allocates the SilcServerEntry context
319 and saves the server info there. The COMMAND_REPLY in
320 the INFO now returns the parameters to application in
321 same order as defined in the protocol specification.
323 The entries are cached in the client->server_cache.
325 * The INFO command is now issued after received the Client ID
326 from the server. Affected file lib/silcclient/client.c.
328 * The CMODE_CHANGE notify may now return also an SilcServerEntry
329 to the application as the mode changer might be server.
330 It is guaranteed that NULL is not returned anymore to the
331 application. Affected file lib/silcclient/client_notify.c.
333 The ID Type is now also passed to the application so that
334 it can check whether the returned entry is SilcClientEntry
337 Added new function silc_client_get_server_by_id to return
338 the server entry by ID. Affected files are the
339 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
341 * Do not create the channel in the Irssi SILC Client when issuing
342 the JOIN command but when received the sucessful JOIN command
343 reply. Otherwise the channel might get created even though we
344 could not join it. The Affected file is
345 irssi/src/silc/core/[silc-channels.c/client_ops.c].
347 * Fixed a channel joining bug in router. The router must also
348 check the channel modes, invite and ban lists etc. when serving
349 the JOIN command sent by normal server. Affected file is
350 silcd/command.c. The router now resolves the client's
351 information from the server who sent the JOIN command if it
352 does not know it, and processes the JOIN command only after
355 * Changed the SilcCommandCb to take new argument; void *context2.
356 Affected file lib/silccore/silccommand.h
358 The second argument in the command callbacks in the server now
359 includes the SilcServerCommandReplyContext if the command was
360 called as pending command callback from the command reply.
361 Otherwise it is NULL. When called as pending the status of the
362 command reply will be checked and if it was erronous the
363 error will be sent to the original sender of the command.
364 This way the client always receives the error messages even
365 though the server was actually the one who received the error
366 when it resent the command to router, for example. Affected
367 files silcd/command[_reply].[ch].
369 * Fixed sending WHOWAS command's error message to client if
370 the requested client could not be found. It was missing.
373 * Changed the CMODE and CUMODE commands reply arguments in the
374 protocol specification. The Channel ID is now sent in both
375 of the commands to identify the channel. Implemented this
376 new feature to the client and server. Affected files
377 lib/silcclient/command_reply.c and silcd/command.c.
379 * Made better checks for invite and ban lists in the JOIN
380 command in server. Affected file silcd/command.c.
382 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
384 * The server now performs the incoming host IP/DNS lookup
385 using the silc_socket_host_lookup and thus does not block
386 the server anymore. Affected file silcd/server.c.
388 * Completed the multi-thread support for SILC Scheduler in
389 the lib/silcutil/silcschedule.c.
391 * Fixed the configure.in.pre to detect the pthread correctly
394 * Fixed a deadlock in silc_task_queue_wakeup in the file
395 lib/silcutil/silctask.c.
397 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
399 * Added new function silc_schedule_wakeup that is used in
400 multi-threaded environment to wakeup the main thread's
401 schduler. It needs to be used when a thread adds a new task
402 or removes a task from task queues. After waking up, the
403 scheduler will detect the task queue changes. If threads
404 support is not compiled in this function has no effect.
405 Implemented the wakeup mechanism to both Unix and WIN32
406 systems. Affected files are lib/silcutil/silcschedule.[ch],
407 lib/silcutil/unix/silcunixschedule.c and the
408 lib/silcutil/win32/silcwin32schedule.c.
410 * Added new function silc_task_queue_wakeup to wakeup the
411 scheduler by the specified task queue. Affected file
412 lib/silcutil/silctask.[ch].
414 * The silc_socket_host_lookup_start now wakes up the scheduler
415 after adding the timeout task. Affected file is
416 lib/silcutil/silcsockconn.c.
418 * The silc_socket_host_lookup is synchronous now if the threads
419 support is not compiled in. However, the callback is still
420 called asyncronously through the scheduler, anyway. Affected
421 file lib/silcutil/silcsockconn.c.
423 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
425 * Added new function silc_socket_host_lookup to perform
426 asynchronous IP and FQDN lookups for the socket connection.
427 Affected files lib/silcutil/silcsockconn.[ch].
429 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Added SILC_MUTEX_DEFINE to define the mutex on environments
432 that may or may not compile the mutex support in.
434 Changed the silc_mutex_alloc interface. It allocates the
435 mutex now to the sent pointer and returns TRUE or FALSE.
437 Affected file lib/silcutil/silcmutex.h.
439 * Wrote the SILC Task Queue interface to support multi-threads.
440 Affected file lib/silcutil/silctask.[ch].
442 * Wrote the SILC Scheduler to support multi-threads. Affected
443 file lib/silcutil/silcschedule.c.
445 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
447 * Implemented the SILC Mutex API and SILC Thread API for WIN32
448 in lib/silcutil/win32/.
450 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Defined SILC Mutex API and SILC Thread API and implemented
453 them for Unix. Affected files are
454 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
455 lib/silcutil/unix/silcunixmutex.c and
456 lib/silcutil/unix/silcunixthread.c.
458 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
460 * Fixed the silc_server_remove_clients_by_server's channel
461 key re-generation. The hash table handling was incorrect
462 and would not work with many channels. Affected file is
465 * Fixed some memory leaks around the server code.
467 * Rewrote the silc_server_get_users_on_channel to support IPv6
468 based Client ID's. Affected file silcd/server.c.
470 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
471 specification. However, a separate document must be written
472 to define the detailed signing procedure and the payload
473 associated with the flag. Defined the flag to the
474 lib/silccore/silcchannel.h as well.
476 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
478 * Changed the dynamic tables to static size tables in the
479 lib/silccrypt/silchmac.c.
481 * Removed GCC dependencies from the code. A patch by cras.
483 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
485 * Do not show the error "Error receiving packet bla bla"
486 in server if it really was not an error (-2 means that reading
487 is pending). Affected file silcd/server.c.
489 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
491 * Fixed a possible crash in silc_server_remove_clients_by_server
492 in silcd/server.c. Fixed there also some memory leaks.
494 * Fixed the silc_idlist_replace_client_id. It could replace
495 wrong key in the hash table. Affected file silcd/idlist.c.
497 * Do not check whether there are global users on the channel
498 if the channel->global_users is FALSE. Affected functions
499 silc_server_remove_from_one_channel and
500 silc_server_remove_from_channels in silcd/server.c. Also,
501 do not check if the removed client is local as we can be
502 sure that global client was not removed from the channel
503 and checking for global users is not needed.
505 * The silc_server_remove_clients_by_server now re-generates
506 the channel keys correctly for those channels that had
507 clients removed from them. Affected file silcd/server.c.
509 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * Found the reason of random crashes in the server. We weren't
512 ignoring the SIGPIPE signal (which can be sent in write())
513 and it crashed the server. Affected file silcd/silcd.c.
515 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Assure that sock->user_data is not NULL in the function
518 silc_server_packet_send in silcd/packet_send.c.
520 * Disconnect the remote connection if it could not be added
521 to any ID lists in the server. The affected file is
524 * Check in silc_server_packet_send[_real/dest] that the
525 socket is not disconnecting and ignore the data if it is.
526 Affected file silcd/packet_send.c.
528 * Define inline to __inline on native WIN32 compilation.
529 Affected file includes/silcwin32.h.
531 * Added some explicit type casts for inline code since MSVC
532 require them. Affected files lib/silcutil/silcbuffer.h,
533 lib/trq/silcdlist.h and lib/trq/silclist.h.
535 * Print warning in log files from now on if the packet
536 decryption fails. Affected file silcd/server.c.
538 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
540 * Changed the `say' client operation's interface to accept
541 new `type' argument to indicate the type of the message sent
542 by the library. The application may filter the library's
543 messages according the type. The affected file is the
544 lib/silcclient/silcapi.h.
546 * Added two new functions to lib/silcclient/silcapi.h:
547 silc_client_del_client and silc_client_del_client_by_id.
548 Affected file lib/silcclient/idlist.c.
550 * Moved the clientincludes.h from includes/ to silc/ and
551 serverincludes.h from includes/ to silcd/.
553 * The modes for the CMODE and CUMODE are now passed as
554 uint32 for application with COMMAND_REPLY. The affected
555 file is lib/silcclient/command_reply.c.
557 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
559 * /WHOIS without arguments shows client's own information.
560 Affected file lib/silcclient/command.c.
562 * Changed PING to not accept any arguments. The specs
563 says that client can ping only the connected server so
564 requiring an argument is not needed. Affected file is
565 lib/silcclient/command.c.
567 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Fixed a fatal bug in private message sending and reception
570 encryption and decryption when using private message keys.
571 The implementation was incorrect and did not follow the
572 specification. It causd that some of the message were
573 lost since it did not use the sending and receiving keys
574 as the protocol suggests. This has been fixed and will cause
575 incompatibilities with older clients when sending private
576 message encrypted with private message keys. Affected files
577 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
578 and various other in Irssi SILC Client.
580 Added `responder' boolean argument to the functions
581 silc_client_add_private_message_key[_ske] to indicate when
582 the key is added as responder or initiator of the key
585 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
587 * Removed the silc_ske_check_version function and created
588 a SilcSKECheckVersion callback. Added also a function
589 silc_ske_set_callbacks that is now used to set all SKE
590 callbacks. The callback functions are not given to
591 the SKE functions anymore, but this function is used to
594 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
596 * Added `silc_version' argument to the silc_client_alloc
597 to define the version of the application for the library.
598 The library will use the version string to compare it
599 against the remote host's (usually a server) version
600 string. Affected file lib/silcclient/silcapi.h
602 * Added the KE protocol context to Key Agreement context
603 in client library so that we can abort the SKE if it
604 is in process when we get timeout. Affected file is
605 lib/silcclient/client_keyagr.c.
607 * Do not resolve the client ID forever if it returns in the
608 first time that such client does not exist. This was done
609 for example with private message. Affected file is
610 lib/silcclient/client_prvmsg.c.
612 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
614 * Do not add regex.h for WIN32. The affected file
615 includes/silcincludes.h.
617 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
618 not work yet 100%. It generates the DLL's automatically
619 when compiling with --with-win32 under cygwin.
621 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
623 * lib/contrib/regex.c is not compiled on WIN32.
625 * Added silc_net_get_socket_opt function to the
626 lib/silcutil/silcnet.h.
628 * Added includes/silcwin32.h for WIN32 specific includes
631 * Do not use ptime structure or any of the posix process
632 functions on WIN32 in lib/silccrypt/silrng.c.
634 * Added silc_gettimeofday to provide generic function
635 for struct timeval on all platforms. Added the function
636 to lib/silcutil/silcutil.h.
638 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Moved the lib/silccore/silcsockconn.[ch] to the utility
641 library as they clearly belong there. As a plus side we
642 can make the actual socket connection routines platform
645 Added also new generic function silc_socket_read and
646 silc_socket_write (that used to be silc_packet_[read/write].
647 The implementation of these are platform specific.
649 * Added WIN32 specific routines of silc_socket_[read/write]
650 to lib/silcutil/win32/silcwin32sockconn.c.
652 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
654 * Added preliminary support for native WIN32 compilation under
655 cygwin (using the -mno-cygwin option for GCC) to the
656 ./configure.in.pre. The --with-win32 now prepares the
657 compilation for native WIN32.
659 * Rewrote the SILC Scheduler interface in the file
660 lib/silcutil/silcschedule.h. The scheduler is now context
661 based and does not have anymore any global static scheduler.
662 Moved the Unix scheduler to the lib/silcutil/unix/ directory
663 and created lib/silcutil/win32 directory for WIN32 based
666 * Added Unix specific network routines to the
667 lib/silcutil/unix/silcunixnet.c and the old
668 lib/silcutil/silcnet.c includes now only generic routines.
670 Added WIN32 specific network routines to the
671 lib/silcutil/win32/silcwin32net.c.
673 * Added Unix specific utility functions from the
674 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
676 * Added WIN32 SILC Scheduler to the file
677 lib/silcutil/win32/silcwin32schedule.c. The code is of course
680 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
682 * Do not handle JOIN notify in the server if the target client
683 is not registered (idata->registered == FALSE). The affected
684 file is silcd/packet_receive.c.
686 * Update the nickrec->founder in event_cumode in the Irssi SILC
687 client. Affected file irssi/src/silc/core/silc-channels.c.
689 * Fixed the CUMODE_CHANGE notify handling in the server when
690 server and router are announcing their clients on channels.
691 Now the mode changes are saved and notified correctly. The
692 affected file is /silcd/packet_receive.c.
694 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
695 They really did not replace the cache entry in the ID Cache.
696 Now they do that. Affected file silcd/idlist.c.
698 * Fixed the KICK notify handling in the Irssi SILC client to
699 update the channel records so that the kicked client does not
700 appear to be on the channel. The affected file is
701 irssi/src/silc/core/silc-channels.c.
703 * Always update the conn->current_channel when executing command
704 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
706 * Fixed the KILL notify handling in Irssi SILC client to remove
707 the killed client on all channels.
709 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
711 * Fixed the silc_parse_command_line to remove extra spaces
712 from the start and end of the arguments. Affected file is
713 lib/silcutil/silcutil.c.
715 * Cancel and free any active protocol in the function
716 silc_server_close_connection. Affected file silcd/server.c.
718 * Cancel and free any active protocol in the function
719 silc_client_close_connction. Affected file is
720 lib/silcclient/client.c.
722 * Do not execute the KILL command for clients that are in
723 history (ie. they are not in the network). Affected file is
726 * Fixed KILL notify handling, client does not crash anymore.
727 Affected file irssi/src/silc/core/silc-channels.c.
729 * Reduced the default packet buffer size from 2048 to 1024 in
730 lib/silccore/silcpacket.c.
732 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
733 counter to the SKE context that is incresed when the SKE library
734 performs async operation outside the library. If the outside
735 process frees the SKE context and FREED status will be set
736 and the library will detect after the sync operation that the
737 libary is freed. The affected files are
738 lib/silcske/silcske[_status].[ch].
740 * Resolve the client entry information in the function
741 silc_client_channel_message to assure that NULL pointer is not
742 passed as client entry to the application. */
744 * Fixed the task timeout calculation to assure that there is
745 never negative timeouts. The affected file is
746 lib/silcutil/silcschedule.c.
748 * Fixed the channel user mode notification sending in server.
749 It was sent point-to-point to the router (or to server by router)
750 but it needs to be destined to a channel. The routines now
751 supports sending the channel user mode notifys to the channels
752 when announcing clients and channels. Affected files are
753 silcd/server.c and silcd/packet_receive.c.
755 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
756 It did not actually replace the old channel entry in the cache.
757 Affected file lib/silcclient/client_notify.c.
759 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Fixed a possible crash in silc_packet_send_prepare. It now
762 assures always that there is enough space in the buffer and
763 at the tail area of the buffer (for MAC).
765 Fixed the inbound buffer reallocation in silc_packet_read.
766 It was old code and did not handle the reallocation correctly.
769 The affected file is lib/silccore/silcpacket.c.
771 * Fixed buffer overflow in silc_parse_nickname in the file
772 lib/silcutil/silcutil.c.
774 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * make install generates new server keys only if there is not
779 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
782 Added check that if the NOREPLY is set then we will not send
783 the away message. This avoids infinite loop of away messages
784 if both clients are away. The affected file is
785 lib/silcclient/client_prvmsg.c.
787 * Fixed client crash if /NICK was given without arguments.
788 Affected file lib/silcclient/command.c.
790 * Server does not send the invite list in INVITE command back
791 to the client if the list was not altered. Added this notion
792 to the protocol spec as well. Affected file silcd/command.c.
794 Fixed possible crash in INVITE command by checking the
795 value of silc_server_get_client_route command.
797 * Fixed the INVITE notify type handling. The arguments are now
798 taken in correct order and client does not crash. The affected
799 file is irssi/src/silc/core/silc-channels.c.
801 Removed the "Inviting xxx to channel" message from the
802 client library away and let the application handle it.
803 Affected file lib/silcclient/command.c. Added that message
804 to Irssi SILC client's message formats.
806 * Fixed CMODE command crash in client. It now checks the
807 amount of arguments correctly and does not crash. The affected
808 file is lib/silcclient/command.c.
810 * Do not create new channel automatically in silc_channels_join
811 but check whether the channel by that name already exists.
812 Affected file irssi/silc/core/silc-channels.c.
814 * Do not send the SERVER_SIGNOFF to router if the disconnected
815 entity was the router. Affected file silcd/server.c.
817 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
818 SILC client as it was missing from there.
820 Added the handling of the KICK notify to the Irssi SILC client
821 as it was missing. Added "you have been kicked" message to
822 Irssi SILC client's message modules formats.
824 Added the handing of the KILL notify to the Irssi SILC client
825 as it was missing. Added the kill message module formats
828 The affected file is irssi/src/silc/core/silc-channels.c.
830 * The router did not save the channel mode the server announced.
831 Affected file silcd/packet_receive.c.
833 * Fixed a possible crash in INFO command in server. If the
834 server did not provide the server info it crashed. Affected
835 file silcd/command.c.
837 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * Fixed the GETKEY command in the server to check also the
840 global list. Otherwise the GETKEY would not work correctly
841 in normal SILC server. Affected file silcd/command.c.
843 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Fixed GETKEY crash, it crashed if the command did not succseed.
847 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
850 is now real and not just an macro interface to GMP.
852 Removed the entire GMP from the source tree and imported new
853 NSS MPI library instead. Reason for removing GMP is that it is
854 extremely large and compiles extremely slow. The NSS MPI
855 is only a few files and compiles in less than 10 seconds.
856 The speed is also about the same as GMP. The MPI is imported
859 If the system has GMP installed we will still use the GMP.
860 If it is not then the NSS MPI will be compiled.
862 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Merged a long nickname (127 characters long) crash bugfix from
865 Irssi CVS tree. Affected file irssi/src/core/misc.c.
867 * Merged a freed memory reference bugfix from Irssi CVS tree.
868 Affected file irssi/src/core/commands.c.
870 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
872 * Added the server's public key sving and verification to the
873 server when performing the SKE. This was missing and the
874 remote server's (or router's) public key was accepted without
875 checking whether we have it previously or trust it at all.
876 Affected file silcd/protocol.c.
878 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Check in the silc_server_timeout_remote if protocol is active
881 and make sure that the protocol's final callback is called so
882 that all memory if freed. Affected file silcd/server.c.
884 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * silc_server_whois_send_reply crashed the server if the nickname
887 was 127 characters long. Affected file silcd/command.c.
889 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Added sanity check to the silc_server_new_client. If the hostname
892 is provided inside username then check that the provided hostname
893 really is the same as the resolved one. If the hostname was not
894 resolved then check it from the public key. Affected file is
895 silcd/packet_receive.c.
897 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
898 if the server disconnected us and the connection is not valid
899 anymore. Affected file irssi/src/silc/core/silc-channels.c.
901 * Moved the silc_client_[chmode|chumode|chumode_char] away from
902 the library to the lib/silcutil/silcutil.[ch].
904 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
906 * Close log file after open. Affected file
907 lib/silcutil/silclog.c.
909 * Check whether sock == NULL in silc_client_send_packet and return
910 if it is. Affected file lib/silcclient/silcclient.c.
912 * Check rec->entry == NULL in the Irssi SILC Client before
913 sending the channel message. Affecte file is
914 irssi/src/silc/core/silc-servers.c.
916 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Merged a splitted window bugfix from Irssi CVS tree. The
919 affected file is irssi/src/fe-text/textbuffer-view.c.
921 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
922 It did not print nickname.
924 * Improved the distributions system a bit.
926 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
929 irssi/src/fe-text/gui-window.c.
931 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
932 to in-active server. The affected file is
933 irssi/src/silc/core/client_ops.c.
935 * Resolve the client in USERS command reply if the entry does
936 not have username resolved. The affected file is
937 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
938 command to WHOIS command to really resolve stuff. The USERS
939 is not used any more in any critical section so WHOIS can
940 be used even though it might be slower than IDENTIFY.
942 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
945 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
947 * Changed the protocol API a bit more consistent in the
948 lib/silccore/silcprotocol.[ch].
950 * Changed the following headers to ROBODoc format:
952 lib/silccore/silcpayload.h
953 lib/silccore/silcprotocol.h
954 lib/silccore/silcsockconn.h
956 All core library headers are now formatted.
958 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Fixed a bug in Irssi SILC client; do not show that you are
961 server/router operator if you really are not. Affected file is
962 irssi/src/silc/core/client_ops.c.
964 * Renamed silc_command_free_payload to silc_command_payload_free.
965 Affected file lib/silccore/silccommand.h
967 * Added silcmath.h to include the prototoypes of various routines
968 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
971 * Changed the following headers to ROBODoc format:
973 lib/silccore/silcchannel.h
974 lib/silccore/silccommand.h
975 lib/silccore/silcid.h
976 lib/silccore/silcidcache.h
977 lib/silccore/silcmode.h
978 lib/silccore/silcnotify.h
979 lib/silccore/silcpacket.h
980 lib/silcmath/silcmath.h
982 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added checking to the server code not to start the server if
985 ciphers and stuff are not configured properly. Affected files
986 silcd/serverconfig.[h] and silcd/server.c.
988 * Changed the layout of the header files of the public interfaces
989 in the SILC libraries. The new layout supports ROBODoc
990 documentation tool (and some others) so that it is easy to create
991 a library reference manual. All the other headers and source
992 code must still follow the CodingStyle document. Also source
993 code must not include these ROBODoc stuffs, only the headers.
994 Furthermore, all public interface headers must now be named
995 by using `silc' prefix, example: silcapi.h, silccipher.h.
996 Some files were renamed due to this. All the other headers
997 must not be used as public interfaces. I will update the
998 CodingStyle document later. Changed following headers, so far:
1000 lib/silcclient/silcapi.h
1001 lib/silccore/silcauth.h
1002 lib/silccore/silcprivate.h
1003 lib/silccrypt/silcdh.h
1005 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Removed silc_client_packet_send_flush from the client library
1010 as it is not needed. Affected file lib/silcclient/client.[ch].
1012 * Added printing of message of unresolved authentication method
1013 to the Irssi SILC client. Added it to the module formats.
1014 Removed the same message from the client library.
1016 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Added new distribution feature, DISTLABEL. Every distribution
1019 can define own preprocessor label that can be used in the
1020 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1021 file distributions, acconfig.h.pre and prepare.
1023 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Added Makefile.defines_int to include the actual definitions
1026 for Makefile.defines.in. Tested the new distribution system,
1027 created distributions and tested installation.
1029 * Added AWAY message printing to the Irssi SILC client. Added
1030 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1032 * Added SCONNECT command to call the SILC's CONNECT command.
1033 Cannot use CONNECT directly since Irssi uses that internally.
1034 Affected file irssi/src/silc/core/silc-servers.c.
1036 Added ACTION local command. It is same as ME command but takes
1037 the channel as mandatory argument.
1039 Rewrote some of the Irssi's help files to suite for SILC
1042 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1044 * Added Makefile.defines[.in] that should for now on be included
1045 in all Makefile.am file in the source tree. That file includes
1046 all common compilation definitions for SILC source tree.
1048 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Minor changes to the ./prepare script to change the package
1051 name according the distribution name to the configure.in.
1053 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Created new distribution system. Added file `distributions'
1056 that defines all the distributions that can be created out of
1057 the SILC source tree. The ./prepare script now reads that
1058 file to determine how to prepare the distributions. The
1059 first argument to the ./prepare is the name of the distribution
1060 and second is the version of the distribution. If given
1061 without arguments it creates the default (toolkit) distribution
1062 with the default version (defined in ./prepare).
1064 All Makefile.am files that are subject to the distributions
1065 are now named as Makefile.am.pre. These are ./Makefile.am
1066 and lib/Makefile.am. Others may be changed later.
1068 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Added invite list, ban list, some key management and connection
1071 error message printing to module formats in the Irssi SILC client.
1073 * Added new silc_client_set_away_message to set the away message
1074 that is back to the person who sent private message. The
1075 affected file lib/silcclient/silcapi.h and the
1076 lib/silcclient/client_prvmsg.c.
1078 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Fixed the private message sending in the Irssi SILC client,
1081 added local command KEY to the Irssi SILC client.
1083 Added key management and key agreement message formats to the
1084 irssi/src/fe-common/silc/module-formats.[ch].
1086 Added USERS (alias WHO) printing, server/router operator
1087 indication and LIST command printing to the module formats.
1089 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Fixed channel joining notify handling, cumode notify handling
1092 from Irssi SILC client.
1094 * Added SILC specific module-formats to the Irssi SILC client so
1095 that SILC specific message hilighting, colors etc is possible.
1096 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1098 Added channel mode, channel user mode, actions, notices,
1099 whois and whowas printing to the the module-formats.c.
1101 * Fixed a bug in channel deletion in the server. The channel
1102 is not left to the cache even if the channel founder auth mode
1103 is set when there are no users anymore on the channel. Affected
1104 file silcd/server.c.
1106 * The silc_net_localhost now resolves the entire hostname including
1107 the domain name. Affected file lib/silcutil/silcnet.c.
1109 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1111 * Changed the ask_passphrase client operation to be ascynchronous.
1112 It has now a completion callback and a context that the
1113 application must call after it has got the passphrase from
1114 the user. Affected files lib/silcclient/silcapi.h,
1115 lib/silcclient/protocol.c, lib/silcclient/command.c and
1118 Added SilcAskPassphrase callback that the application calls
1119 to deliver the passphrase to the library.
1121 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1122 The public key verification and especially a certificate
1123 verification is asynchronous procedure.
1125 Added new SILC_SKE_STATUS_PENDING status to indicate the
1126 request is pending and a callback will be called to finalize
1129 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1130 indicate that remote end did not send its public key (or
1131 certificate), even though we require it. Added check for this
1132 condition in the SKE. This was a security bug, now fixed.
1134 Defined new SilcSKEVerifyCbCompletion callback that is called
1135 when the verification process is completed.
1137 The affected files lib/silcske/silcske_status.h and
1138 lib/silcske/silcske.[ch].
1140 * Changed the verify_public_key client operation to be async
1141 as well. Defined SilcVerifyPublicKey callback that is used to
1142 indicate the success of the public key verification process.
1144 Changed the server and client to use the new async client
1147 * Changed the Irssi SILC client's internal scheduler to be called
1148 twice as many times as it used to be. As a result the client
1149 should be a bit faster now. Affected file is
1150 irssi/src/silc/core/silc-core.c.
1152 * Added support to Irssi SILC client of asynchronous public key
1153 verification and passphrase inquiry. Affected file is
1154 irssi/src/silc/core/silc-core.c.
1156 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1158 * Do not say "You have left channel %s" in client library.
1159 Moved it to the application. Affected files are
1160 lib/silcclient/command.c and silc/client_ops.c.
1162 * Fixed silc_client_get_clients. Command context was not
1163 duplicated and was freed memory in the callback. Affected
1164 file lib/silcclient/idlist.c.
1166 * Do not say "you are now talking..." on JOIN command in the
1167 client library. The appliation must handle it.
1169 * Do not say ".. changed topic to" in command reply in the
1170 client libary. The application must handle it.
1172 * Fixed TOPIC command sending in the client library.
1174 * Fixed a memory leak in silc_client_command_free in the file
1175 lib/silcclient/command.c.
1177 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Imported a modified version of Irssi client to the source tree.
1180 The Irssi will be used to create a new client called
1181 Irssi SILC. Imported to irssi/.
1183 Added silc_core_init_finish function to the Irssi. Affected
1184 file irssi/configure.in.
1186 A lot changes in the Makefile.ams around the irssi tree.
1188 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Do not rehash if the new size is same as the old size of the
1191 hash table, in the silc_hash_table_rehash*. The affected file
1192 lib/silcutil/silchashtable.c.
1194 * Replaced hash_table_del_by_context calls from the server
1195 (when channel->user_list and client->channels) to the
1196 hash_table_del as it is sufficient and faster.
1198 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1200 * Added silc_hash_table_list, silc_hash_table_get and the
1201 SilcHashTableList structure to provide an alternative way to
1202 traverse the hash table. The affected files are
1203 lib/silcutil/silchashtable.[ch].
1205 * Changed the server's idlist routines to use the hash table
1206 routines to optimize the code.
1208 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Replaced the client entry's `channel' list and channel entry's
1211 `user_list' list to hash tables for optimized lookup. Changed
1212 the code to use the hash table interface around the code.
1213 Affected file lib/silcd/idlist.[ch].
1215 * Added `auto_rehash' boolean argument to the function
1216 silc_hash_table_alloc to indicate whether the hash table should
1217 auto-rehash when it thinks is appropriate time. It will
1218 increase the hash table size if the there is twice as much
1219 entries in the table than the size of the table, and will
1220 decrease the size if there are twice as less entries than
1221 the size of the table.
1223 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1227 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * silc_idcache_purge_by_context deletes the entry now by context
1230 as it is supposed to do. Affected file lib/silccore/idcache.c.
1232 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1233 client is not anymore valid (WHOWAS givens the info) and not
1234 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1236 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Removed the `data' and `data_len' arguments from the ID Cache
1239 interfaces and added `name' argument. ID Cache does not handle
1240 anymore the binary data only a names associated with given ID.
1242 * When hashing a Client ID with silc_hash_id the entire ID is
1243 not hashed anymore, instead only the hash of the Client ID is
1244 hashed. This way we can access the Client ID from the cache
1245 with Client ID but with the hash of the ID (which is a hash of
1246 the nickname) as well without any difference in performance.
1248 Added also silc_idcache_find_by_id_one_ext to do one on one
1249 searching when we have the actual ID. Added also function
1250 silc_hash_client_id_compare. The affected files are
1251 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1253 * When hashing the name associated with a ID it is always done
1254 in lowercase. This way we can access the cache without worrying
1255 about case-sensitivity, even though, for example nicknames are
1258 * Fixed a bug in server with channel message sending. It put
1259 wrong ID type as destination ID. The affected file
1260 silcd/packet_send.c.
1262 * silc_idcache_del_by_context now deletes from all hash tables
1263 by context. Affected file lib/silccore/idcache.c.
1265 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Changed the client library to use the new ID Cache interface.
1268 Changes around the source tree.
1270 * Added silc_hash_table_rehash_ext to rehash with specific
1271 hash function. Affected file lib/silcutil/silchashtable.[ch].
1273 * Added silc_hash_string_compare to compare two strings in the
1274 hash table. Affected file lib/silcutil/silcutil.[ch].
1276 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Added new function silc_idcache_del_by_context into the
1279 lib/silccore/idcache.[ch].
1281 * Changed the server's ID list routines to use the new ID Cache
1282 interface. Changes around the source tree.
1284 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Added silc_hash_table_del[_by_context]_ext functions in to the
1287 lib/silcutil/silchashtable.[ch].
1289 Removed silc_hash_table_find_all* routines and added new
1290 silc_hash_table_find_foreach to replace them.
1292 Added silc_hash_table_replace_ext function as extended
1293 replacing function. Separated the simple hash table interface
1294 from the extended hash table interface in the file
1295 lib/silcutil/silchashtable.h.
1297 * Fixed minor bugs and changed it to use some of the new
1298 hash table functions in lib/silccore/idcache.c
1300 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Added new function silc_hash_table_find_all to return all keys
1303 in the hash table by the specified key. As the hash table is
1304 collision resistant it also makes it possible to have several
1305 duplicate keys in the hash table. This function may be used to
1306 find all of the keys from the hash.
1308 Added user_context arguments to the SilcHashFunction,
1309 SilcHashCompare and SilcHashDestructor to deliver user specified
1312 Added new fuctions silc_hash_table_find[_all]_ext to do
1313 extended lookup with specified hash and compare functions and
1314 specified user contexts.
1316 Added new function silc_hash_table_add_ext to add the key
1317 with specified hash function and user context.
1319 Added new function silc_hash_table_foreach to traverse all
1320 entrys in the hash table. Added SilcHashForeach callback
1323 Added new function silc_hash_table_del_by_context to delete
1324 the entry only if the context associated with the key matches.
1326 Affected files are lib/silcutil/silchashtable.[ch].
1328 * Removed silc_hash_[server/client/channel]_id and added just
1329 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1330 silc_hash_id_compare to compare two ID's using as the hash table
1331 comparison function. Added also silc_hash_data to hash
1332 binary data and silc_hash_data_compare to compare it.
1334 * Removed silc_idlist_find_client_by_hash as it is not needed
1335 anymore. Affected file silcd/idlist.[ch].
1337 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1338 to use internally the SilcHashTable. The new ID Cache is a lot
1339 faster than the old one. Some of the ID Cache interface was also
1340 rewritten and obsolete and stupid functions were removed.
1342 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Added entry_count field to the SilcHashTable to keep the number
1345 of the entries in the table. Implemented the function
1346 silc_hash_table_rehash. Added new function
1347 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1349 Fixed a minor bug in silc_hash_table_free.
1351 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1352 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1353 into the lib/silcutil/silcutil.[ch].
1355 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * Implemented a collision resistant hash table into the
1358 lib/silcutil/silchashtable[ch]. See the header and the source
1359 for the SilcHashTable API.
1361 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Merged dotconf version 1.0.2 into lib/dotconf.
1365 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Do not compile anything in lib/silcsim/* if the SIM support
1368 is not enabled. The tree should now compile without problems
1371 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1373 * Compiled the SILC under cygwin. Compiled and tested briefly
1374 without problems. More tests needed. The SIMs didn't compile
1377 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1379 * Fixed possible crash in silc_get_username in the
1380 lib/silcutil/silcutil.c.
1382 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Fixed a va_arg in silc/client_ops.c.
1386 * Oops, RC5 routines were named AES and caused some problems
1387 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1389 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1391 * Added new SilcIDIP structure into the lib/silccore/id.h and
1392 replaced the old `ip' fields from all SILC ID's to that type.
1393 This is a step towards IPv6 support.
1395 The silc_id_get_len takes now the ID as an extra argument.
1396 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1397 both IPv4 and IPv6 based ID's.
1399 The affected files are lib/silccore/id.[ch] and other files
1400 around the tree using these routines.
1402 * Removed the ID length arguments in server from various
1403 silc_server_send_notify_* routines -> they are not needed
1406 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1408 * Fixed memory leak in silc_encode_pem_file in the file
1409 lib/silcutil/silcutil.c.
1411 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Check minor version as well in the SKE. Affected files are
1414 silcd/protocol.c and lib/silcclient/protocol.c.
1416 * Added --identifier option to the server so that an identifier
1417 can be when creating the public key for the server. Affected
1418 file is silcd/silcd.c.
1420 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1421 lib/silccrypt/silcpkcs.c.
1423 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Register default ciphers and stuff when using -C option with
1426 the server. Affected file sildc/silcd.c.
1428 * Put back the servers public key filename format, it is better
1429 than the new one. For now, the client keys are saved with the
1430 new filename format. The affected file silc/client_ops.c.
1432 * Implemented the Cipher API for the rest of the ciphers that
1433 did not implement it or implemented it the wrong way.
1435 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Register default ciphers and stuff when using the -S option
1438 in the client. Affected file silc/silc.c. Same also when
1439 creating new key pair with -C option.
1441 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Fixed the silc_verify_public_key client operation function to
1444 save the public keys differently. The fingerprint is now
1445 used as filename and not the hostname. This way also the
1446 client keys are saved uniquely and not with hostnames. The
1447 affected file is silc/client_ops.c.
1449 * Trimmed the silc_hash_fingerprint function to remove extra
1450 whitespaces from the end of the fingerprint. The affected
1451 file is lib/silccrypt/silchash.c.
1455 * Added silc_cipher_register_default function to register all
1456 default ciphers. It can be used when configuration files
1457 does not exist and the application does not want any specific
1458 ciphers in any specific order.
1460 The SilcDList is now used as silc_cipher_list dynamically
1461 allocated cipher list. Removed the static list all together
1462 and now all ciphers must be allocated to the dynamic list.
1463 The silc_cipher_alloc routine was changed to check only the
1466 All silc_cipher_* routines that used to return int returns
1469 The affected files lib/silccrypt/silccrypt.[ch].
1471 * The same thing was done to silc_hash_* as for silc_cipher_*
1472 routines. Affected files lib/silccrypt/silchash.[ch].
1474 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1475 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1476 Added also silc_pkcs_[un]register[_default] functions.
1477 Removed the data_context from the PKCS API.
1479 * Added silc_hmac_register_default function to register default
1480 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1481 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1482 to unregister all hmacs at once.
1484 * Register the default ciphers, hash functions, PKCSs and HMACs
1485 if client's configuration file does not exist. The affected
1488 * The client did not load the hash functions from the SIM
1489 modules at all. Added support for this. Affected file is
1490 silc/clientconfig.c.
1492 * When decoding public key with silc_pkcs_public_key_decode, check
1493 the supported algorithm only if PKCS are registered. Affected
1494 file lib/silccrypt/silcpkcs.c. The same was done with the
1495 silc_pkcs_private_key_decode.
1497 * Fixed the SILC List routines to keep the list always in order.
1498 It used to change the list's order when traversing the list but
1499 not it preserves the order. Affected file lib/trq/silclist.h.
1501 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Added the client library to use the SilcSocketConnection's
1504 reference counter (by silc_socket_dup) to prevent the bug that
1505 the socket object may be freed underneath async operation.
1507 * The name resolv library checking fixes in the configure.in.pre.
1510 * Created new version of the protocol drafts for future
1511 development. The -03 drafts are the ones that will be changed
1512 in the trunk now and the -02 will remain as they are.
1514 * Send list of CUMODE notifys to the router when announcing
1515 the channel users to the router. Affected file silcd/server.c.
1516 If the router receiving channel founder CUMODE for a channel
1517 that already has channel founder it will send CUMODE notify
1518 to the sender to remove the channel founder rights from the
1519 announced client. Affected file silcd/packet_receive.c.
1521 * The CUMODE notify may now use Server ID as well as the entity
1522 who changes the mode. Updated protocool specs.
1524 * Updated INSTALL and README files.
1526 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * New web pages in the http://silc.pspt.fi. The pages was
1533 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Implemented the [DenyConnectin] config section in the server.
1536 Added silc_server_config_denied_conn to check whether incoming
1537 connection is denied. Affected file silcd/serverconfig.[ch].
1539 * Do not check the ports when checking the incoming configuration
1540 data if the port is 0, meaning any. Affected file is
1541 silcd/serverconfig.c.
1543 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1545 * Fixed buffer overflow in silc_string_compare in the file
1546 lib/silcutil/silcutil.c.
1548 * Fixed double free in silc_server_command_leave in the file
1551 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Fixed the version checking in the server. Affected file is
1556 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1558 * Fixed the configuration data fetching when accepting new
1559 connections in the server. Affected file silcd/server.c.
1561 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Added `sender_entry' argument to the function
1564 silc_server_packet_relay_to_channel so that we can check
1565 whether some destination actually belongs to the same route
1566 the sender belongs (ie, we must not resend the packet to the
1567 sender). Affected file silcd/packet_send.[ch].
1569 * Added `servername' field to the SilcClientEntry in the server
1570 to hold the name of the server where client is from. Affected
1571 file is silcd/idlist.h.
1573 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1575 * Moved the channel message encrypting in the router betwen
1576 router connections from silc_server_channel_message to the
1577 silc_server_packet_relay_to_channel since we want to check
1578 whether we have anybody channel before encrypting anything.
1579 Affected files silcd/packet_[receive/send].c.
1581 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Fixed the [AdminConnection] server config section to support
1584 multiple entries. Affected file silcd/serverconfig.c.
1586 * Added support into the server to check the validity of the
1587 incoming connection before executing any KE or authentication
1590 * The connection configuration is now saved to the KE and
1591 connection auth protocol contexts and not fetched anymore in
1592 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1594 * The local hosts listenning address and port is also resolved
1595 now when starting the server. We want to have the socket object
1596 to include the real address and port for the listener. Added
1597 new function silc_net_check_local_by_sock into the files
1598 lib/silcutil/silcnet.[ch].
1600 * Fixed a broadcast bug in server -> do not broadcast if we
1603 * Fixed a routing bug. Do not route broadcast packets ever.
1604 Broadcast packets must be processed always and not routed since
1605 they may be destined to some other host than yourself and thus
1606 would get routed without no good reason. Affected file is
1609 * Added function silc_server_config_is_primary_route to check
1610 whether primary router connection has been configured (a router
1611 configuration that we are initiating). If there is not, we
1612 will assume that there is only two routers in the SILC network
1613 and we will use the incoming router connection as our primary
1614 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1616 * Changed the order of the broadcasting. Broadcast _after_ the
1617 packet has been processed not before. Affected file is
1620 * Fixed a [ClientConnection] parsing bug. The port was never
1621 parsed correctly thus resulting to port 0. Affected file
1622 silcd/serverconfig.c.
1624 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1625 argument and did not set the broadcast packet flag. Affected
1626 file silcd/packet_send.c. Fixed same bug in the function
1627 silc_server_send_notify as well.
1629 * If we receive NEW_ID packet for our own ID in the server, ignore
1632 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1636 * Removed the nickname from the Private Message Payload.
1637 Updated the code and the protocol specs.
1639 * Updated protocol specs for submitting to the IETF.
1641 * Tweaked the Random Number Generator a bit. Affected file
1642 lib/silccrypt/silcrng.c. Exported a new function
1643 silc_rng_[global]_add_noise which can be used to add more
1646 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1648 * Do not parse packets with different timeout when protocol
1649 is active -> may cause problem with rekey. Affected file
1652 * When server receives signoff notify it must not create
1653 new channel key if the client is on any channels since the
1654 sender of the signoff notify will create it.
1656 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1658 * Added printing of error messages during SKE protocol from the
1659 failure packet sent by server during SKE. Affected file
1662 * Removed the client's failure_callback handling with timeout
1663 and handle it immediately when received.
1665 * The SKE library returned wrong type in SUCCESS and FAILURE
1666 packets. They must be 32 bit MSB not 16 bit MSB.
1668 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Ok, rewrote the logic of the re-key and now it seems to work.
1671 I tested it on high traffic with frequent re-keys without
1672 problems. Added hmac_receive (and renamed hmac to hmac_send)
1673 in SilcClientConnection in lib/silcclient/client.h and
1674 in SilcIDListData in silcd/idlist.h. Also, removed the
1675 SilcPacketParserContext's cipher and hmac fields as they are
1676 not needed anymore and actually caused some problems when
1677 the ciphers and hmac's changed underneath the packet parser.
1679 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1681 * If re-key protocol is active then process the incoming packets
1682 synchronously since we must assure that icoming packets encrypted
1683 with the old key is processed before the new keys is set to
1684 use. This is true other packets than for REKEY packets.
1685 Affected file silcd/server.c. The same was done to client library
1686 as well, affected file lib/silcclient/client.c.
1688 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * Fixed bug in client and server to accept the force send if
1691 the packet is send from silc_[server/client]_packet_process
1692 function. Otherwise the packets are never delivered, oops.
1694 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Disable force sending of packets when REKEY protocol is active.
1697 We must assure that no packet is sent directly when rekey is
1698 performed. All packets must be sent through packet queue.
1699 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1700 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1701 function is silc_[server/client]_packet_send_real to check
1704 * Replaced the SIM paths from example config files to
1705 /usr/local/modules. Also, make install creates now
1706 /usr/local/silc/logs directory to hold all the SILC server
1709 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Made the configure.in.pre work on Solaris. Patch by salo.
1713 * Made all ciphers compatible with non-x86 machines. Defined
1714 CBC mode macros into lib/silccrypt/ciphers_def.h.
1716 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Fixed the make install.
1720 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * When MAC computation fails the silc_packet_decrypt returned 0
1723 even though it was supposed to return -1. Fixed this. The
1724 affected file is lib/silccore/silcpacket.c.
1726 * Do not replace the config files in /etc/silc (in make install)
1727 if they already exist. Affected file ./Makefile.am.
1729 * Do not send re-key packets immediately but through packet queue.
1730 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1732 * Changed silc_net_check_host_by_sock to return FALSE if the
1733 IP/DNS could not be resolved. Though, it returns the IP address
1734 now even if it could not resolve it (but returns also FALSE).
1735 Affected file lib/silcutil/silcnet.[ch].
1737 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1739 * Added silc_pkcs_decode_identifier to decode the public key's
1740 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1741 Added also silc_pkcs_free_identifier. Added also new context
1742 SilcPublicKeyIdentifier.
1744 * Added -S option to the silc client. It is used to dump the
1745 contents of the specified public key file.
1747 * Changed the PKCS api to return the public key length when
1748 setting the public key.
1750 * Fixed a fatal bug in the public and private key file loading.
1751 Affected file lib/silccrypt/silcpkcs.c.
1753 * Execute the packet parsing for client with zero (0) timeout
1754 if the protocol is active. Affected file silcd/server.c.
1756 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Made the key generation options to the silcd program. Added
1759 -C option, equivalent to client's option.
1761 * Added new [ServerKeys] config section to the server. It
1762 configures the server's public and private key.
1764 * Defined generic Public Key Payload into the protocol
1765 specification to send specific type of public keys and
1768 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1769 public key or certificate.
1771 * Implemented the GETKEY command to the server and to the
1772 client library and on user interface.
1774 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Made preliminary `make install' work.
1778 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Added SilcServerRekey context into silcd/idlist.h.
1782 * Added the PFS support as defined in the specification to the
1783 SKE protocol. Affected files lib/silcske/*.c.
1785 * Added `ske_group' field to the SilcServerRekey context to hold
1786 the number of the SKE group that is used with PFS in re-key.
1787 Affected file silcd/idlist.h.
1789 * Added PFS re-key support to the server. Affected file is
1792 * Added silc_protocol_cancel to cancel execution of the next
1793 state of the protocol. Affected file is
1794 lib/silccore/silcprotocol.[ch].
1796 * Added the re-key support with and without PFS to the client
1797 library. Re-key is performed once in an hour, by default.
1799 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1800 Added silc_client_rekey_callback and silc_client_rekey_final.
1801 Affected files are lib/silcclient/protocol.[ch] and
1802 lib/silcclient/client.[ch].
1804 * Removed the `hmac_key' and `hmac_key_len' fields from the
1805 SilcClientConnection structure; not needed. Affected file is
1806 lib/silcclient/client.h.
1810 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1812 * Do not ask whether user wants to use the negotiated private key
1813 for private messages, just use it. Affected file is
1814 silc/local_command.c.
1816 * Added `send_enc_key' and `enc_key_len' fields to the
1817 SilcIDListData structure since they are needed in the re-key
1818 phase. Affected file is silcd/idlist.[ch].
1820 * Implemented the simple re-key protocol into the server.
1821 Affected files silcd/server.c and silcd/protocol.[ch]. The
1822 re-key will be performed once in an hour, by default.
1824 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1825 Added silc_server_rekey, silc_server_rekey_callback and
1826 silc_server_rekey_final.
1828 * Removed Tunneled flag from the protocol. Updated the code
1829 and the specifications.
1831 * Adde `pfs' field to the SilcIDListData to indicate whether
1832 the PFS is to be performed in the re-key. Affected file is
1835 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1838 int64 of at least the xintXX size. If void * is less that 4
1839 bytes uint32 * will be used. Defined bool as boolean.
1841 * Changed _ALL_ unsigned long and unsigned int to uint32,
1842 unsgined short to uint16 in the source tree.
1844 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1845 not handle clients that has entry->data.registered == FALSE.
1846 They are not in the network anymore. Affected file is
1849 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Implemented the sending of the SERVER_SIGNOFF notify in the
1852 server. Affected file is silcd/server.c.
1854 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1855 Added also silc_notify_payload_encode_args into the
1856 lib/silccore/silcnotify.[ch].
1858 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1859 Affected file silcd/packet_receive.c.
1861 * Implemented the SERVER_SIGNOFF notify handling in the client
1862 library. Affected file lib/silcclient/client_notify.c. Also,
1863 implemnted the printing of the SERVER_SIGNOFF info to the
1864 application. Affected file silc/client_ops.c.
1866 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1867 if the deleting was successful. Affected file silcd/idlist.[ch].
1869 * Added support for public key authentication in the connection
1870 authentication protocol in the client library. Affected file
1871 lib/silcclient/protocol.c.
1873 * Changed the server's silc_idlist_get_clients_by_* interface
1874 to support already allocated array so that new entries may be
1875 added to pre-allocated array. Affected file silcd/idlist.[ch].
1876 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1877 and command replies.
1879 * All command reply functions in the server now calls the
1880 pending command callback even if error occured. This way the
1881 error will be delivered to the client as well. Affected files
1882 silcd/command.c and silcd/command_reply.c.
1884 * Fixed INFO command to return local server's info if no server
1885 was provided. Affected file lib/silcclient/command.c.
1887 * Removed RESTART command for good. Updated the code and the
1890 * Rewrote parts of the task system. It is a bit simpler now.
1891 Removed unsued task priorities. The affected files are
1892 lib/silcutil/silctask.[ch].
1894 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Moved the USERS printing from the library to the application.
1897 Affected files lib/silcclient/command.c and silc/client_ops.c.
1899 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Added channel key re-key support. The re-key is perfomed
1904 only by the router and is done once in an hour. Added `rekey'
1905 field to the SilcChannelEntry in the server. Affected files
1906 silcd/server.c and silcd/idlist.h.
1908 * Added silc_task_unregister_by_context into the file
1909 lib/silcutil/silctask.[ch].
1911 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Added SILC_UMODE_GONE mode to indicate when the client is not
1914 present in the SILC network. Added also support to the local
1915 command AWAY that will set this mode. Added support of showing
1916 "xxx is gone" in WHOIS command. The USERS command shows the
1917 gone status as well.
1919 * Fixed setting server and router operator privileges in the
1920 server's UMODE command. Affected file silcd/command.c.
1922 * Merged the SKE KE1 and KE2 payloads into one payload. The
1923 new KE payload is equivalent to the old KE2 payload.
1925 Cleaned up the SKE Start Payload parsing. It now uses the
1926 simple buffer unformatting to do the parsing. A lot faster
1929 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1930 to the SKE that is used to indicate whether both of the SKE
1931 parties should perform authentication. By default only the
1932 responder performs authentication. By setting this flag also
1933 the initiator must do authentication. By default it is unset
1934 since in normal SKE case, client to server connection, only
1935 the responder should do authentication. When doing SKE between
1936 two clients both should perform authentication. Updated the
1937 code and the protocol specs.
1939 * A little fix to IDENTIFY command in the server. Search the
1940 client first by hash not nickname. Affected file is
1943 * Fixed the silc_client_close_connection to support closing
1944 the client to client connections wihtout deleting too much
1945 data. Affected file lib/silcclient/client.c.
1947 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1948 are received if protocol used to be active but is not anymore
1949 the application would crash due to NULL pointer dereference.
1950 Affected files silcd/server.c and lib/silcclient/client.c.
1952 * Added `hash' field to the SilcClientConnection to include
1953 the hash function negotiated in the SKE protocol.
1955 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1956 to set the channel founder authentication data. A client can
1957 claim the founder rights later by providing the authentication
1958 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1959 This way the channel founder can regain the channel founder
1960 privileges even it is left the channel. This works only on
1961 local server and the client must be connected to the same
1962 server to be able to regain the founder rights. Updated the
1963 protocol specs accordingly.
1965 Added support to the CMODE command in the client to set the
1966 founder auth data. Read the README to see how to set it.
1968 Added support to the CUMODE command to claim the founder
1969 rights. Read the README to see how to do it.
1971 Added support for the founder authentication to the Channel
1972 Entry in the server. Affected file silcd/idlist.h.
1974 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1975 server's CMODE command. Affected file silcd/command.c.
1977 * Added the following new functions into lib/silccore/silcauth.[ch]:
1978 silc_auth_get_method and silc_auth_get_data.
1980 * The server now saves the remote hosts public key to the
1981 SilcIDListData pointer. Affected file silcd/protocol.c.
1983 * The normal server now does not remove the channel entry from
1984 the cache if the founder authentication data is set. It used
1985 to remove it if the founder was the last one on the channel on
1986 the server and left the channel. The auth data is saved and
1987 if the channel is re-joined later the old entry is used with
1988 the old auth data. Affected files silcd/command_reply.c and
1991 * Removed the `pkcs' field from the SilcIDListData structure
1992 in the server; it is not used. Affected file silcd/idlist.h.
1994 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Fixed packet processing on slow links. Partial packets were
1997 never re-processed because the incoming data buffer was cleared
1998 by the application. Application must not directly clear the
1999 sock->inbuf, the packet processing routines handle it. Fixed
2000 this in client library and in server.
2002 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2004 * Fixed the WHOIS and IDENTIFY send reply function to really
2005 check whether to send list or just one entry. Affected file
2008 * Cleaned up the LEAVE command's channel key distribution. The
2009 affected file silcd/command.c.
2011 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2012 can enforce the channel mode as well. In that case the ID
2013 includes the ID of the server. The code now enforces the
2014 mode change if the router have different mode than the server.
2016 * The notify client operation with CMODE_CHANGE notify can now
2017 return NULL client_entry pointer if the CMODE was not changed
2018 by client. Application must check for this.
2020 * Added <Server ID> argument to INFO command to support server
2021 info fetching by Server ID.
2023 * Added silc_server_announce_get_channel_users to get assembled
2024 packets of channel users of the specified channel. Affected
2025 file silcd/server.[ch].
2027 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2028 was freed underneath the ID Cache.
2030 * Re-announce clients when the server received CHANNEL_CHANGE
2031 notify from the router. Affected file silcd/packet_send.c.
2033 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2036 crashed since it did not handle the fact that there is no cipher
2037 called "3" and didn't check the error condition. Now fixed.
2039 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2040 flag. It can be used to send message requests.
2042 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Implemented the RESTART command in the client.
2046 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2047 notice type messages. Added notice printing to the user
2050 * The channel keys are not re-generated if the channel's mode
2051 is PRIVKEY, ie private key on the channel exists. Affected
2052 files silcd/server.c and silcd/command.c.
2054 * Fixed a little bug in channel message delivery when channel
2055 private keys are set in the server. Affected file is
2056 silcd/packet_send.c.
2058 * Changed the setting on channel->on_channel = TRUE from the
2059 silc_client_save_channel_key to the JOIN command reply. The
2060 key payload is not received if the private channel key is set.
2061 Affected file lib/silcclient/command_reply.c and the
2062 lib/silcclient/client_channel.c.
2064 * When the CMODE_CHANGE notify is sent and the channel private
2065 key mode is removed the channel key must be re-generated in
2066 other cells as well. Added this support for the router in the
2067 silcd/packet_receive.c.
2069 * Added new local command NOTICE to send notice message on
2070 channel. Affected file silc/local_command.[ch].
2072 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * Added new local command ME to the client. It is used to send
2075 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2076 some action. Affected file silc/local_command.[ch].
2078 * Changed channel_message and private_message client operations
2079 to deliver the message flags to the application. Added also
2080 the `flags' arguments to the silc_client_send_channel_message
2081 and silc_client_send_private_message functions. Affected file
2084 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Redefined the Private Message Payload to support private message
2087 keys and to support the new private message flags. Updated
2088 the protocol specs. Flags makes it possible to have for example
2089 CTCP style messages.
2091 * Added new type SilcPrivateMessagePayload and defined an API
2092 for it in the lib/silcclient/silcprivate.[ch].
2094 * Tested private message private keys successfully. Tested the
2095 private message key set, unset and list commands with the new
2098 * Redefined the Channel Message Payload to include the channel
2099 message flags (equal with private message flags) to support
2100 for example CTCP style messages.
2102 * Defined some of the message (for channel and private message)
2103 flags. Updated the protocol specs and added the flags to the
2104 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2106 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Added SilcKeyAgreementStatus type to the key agreement routines
2109 to indicate the current status and error if one occured.
2110 The status types are defined in the lib/silcclient/silcapi.h.
2112 * Added new local command KEY that is used to set and unset private
2113 keys for channels, set and unset private keys for private messages
2114 with remote clients and to send key agreement requests and
2115 negotiate the key agreement protocol with remote client. The
2116 key agreement is supported only to negotiate private message keys,
2117 it currently cannot be used to negotiate private keys for channels,
2118 as it is not convenient for that purpose.
2120 * Fixed a minor pending callback setting bug in the function
2121 silc_client_get_client_by_id_resolve, now the function works.
2122 Affected file lib/silcclient/idlist.c.
2124 * Added function silc_net_get_local_port to get local bound
2125 port by socket. Added to lib/silcutil/silcnet.[ch].
2127 * Added `sockets' and `sockets_count' fields to the SilcClient
2128 object. They hold the sockets of the listenning sockets in
2129 the client. Listenning sockets may be for example the key
2130 agreement server. Affected file lib/silcclient/client.[ch].
2131 Added functions the silc_client_add_socket and the
2132 silc_client_del_socket. They are exported to the application
2135 * Added ~./silc/clientkeys to support other client's public keys.
2137 * Renamed verify_server_key client operation to verify_public_key
2138 and added one argument to indicate the type of the connection
2139 (server, client etc.).
2141 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added silc_server_connection_auth_request to handle the
2144 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2145 silcd/packet_receive.[ch].
2147 * Added silc_server_send_connection_auth_request into the
2148 silcd/packet_send.c to send the connection auth request packet.
2150 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2153 * Fixed the public key authentication in responder side in the
2154 server. The `auth_data' pointer includes the SilcPublicKey
2155 not the path to the public key. Affected file silcd/protocol.c.
2157 * Implemented the public key authentication in the initiator side
2158 in the server. Affected file silcd/protocol.c.
2160 * Removed the [RedirectClient] config section from the server
2161 configuration. Is not needed and I don't want to implement it.
2163 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Cleaned up the CMODE command in the server. It now works
2166 correctly and supports all the modes defined in the protocol.
2167 Affected file is silcd/command.c.
2169 * Added `hmac_name' field to the SilcChannelEntry in the server
2170 to hold the default HMAC of the channel. It can be set when
2171 creating the channel (with JOIN command). Affected files
2174 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2175 type to indicate the change of the current cipher and hmac
2176 on the channel. Client can safely ignore the <cipher> argument
2177 (if it chooses to do so) since the CHANNEL_KEY packet will
2178 force the channel key change anyway. The <hmac> argument is
2179 important since the client is responsible of setting the new
2180 HMAC and the hmac key into use.
2182 * Fixed the CMODE command in the client library as well.
2184 * Tested CMODE command in router environment successfully.
2186 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Show the version of the remote client (or server) when connecting
2189 to the server. It is logged to the log file. Affected file
2190 is silcd/protocol.c.
2192 * Fixed the KILLED notify handling in the client library. The
2193 client must be removed from all channels when receiving the
2196 Also, do not remove the client entry when giving the KILL
2197 command but when the KILLED notify is received.
2199 * Removed silc_idlist_find_client_by_nickname from the server.
2200 Not needed anymore. Affected files silcd/idlist.[ch].
2202 * Implemented the CHANNEL_CHANGE notify type handling to the
2203 server. Affected file silcd/server.c.
2207 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Added silc_server_send_notify_invite to send the INVITE
2210 notify between routers.
2212 * Implemented the INVITE command correctly to the server.
2214 * Implemented the INVITE notify type handling in the server.
2216 * Implemented the INVITE command to the client library and on the
2219 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Added function silc_server_get_client_resolve to find the
2222 client entry by ID from all ID lists and then resolve it
2223 (using WHOIS) if it cannot be found. Affected file is
2226 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Implemented the BAN command to the client library.
2230 * The JOIN command in the server now checks the invite list
2233 * Changed the silc_command_reply_payload_encode_va and the
2234 silc_command_payload_encode_va to support that if argument is
2235 NULL it ignores and checks the next argument. Affected file
2236 lib/silccore/silccommand.c.
2238 * Added silc_server_send_notify_ban to send the BAN notify
2239 type between routers.
2241 * Chaned the silc_notify_payload_encode to support that if
2242 argument is NULL it ignores and checks the next argument.
2243 Affected file lib/silccore/silcnotify.c.
2245 * Tested ban lists in router environment successfully.
2247 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Implemented BAN command to the server, in silcd/command.[ch].
2251 * Removed the BAN and INVITE_LIST modes from the CMODE command
2254 * Added function silc_string_match to regex match two strings.
2255 Affected files lib/silcutil/silcutil.[ch].
2257 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Redefined parts of the SilcChannelEntry in the server to support
2260 the new ban and invite lists.
2262 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Redefined the INVITE command. The same command can be used to
2265 invite individuals to the channel but also to manage the invite
2266 list of the channel (to add to and remove from the invite list).
2267 Updated the protocol specs.
2269 * Added new command SILC_COMMAND_BAN that can be used to manage
2270 the ban list of the channel. Updated the protocol specs.
2272 * Removed the channel modes: the SILC_CMODE_BAN and the
2273 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2274 in the CMODE command. The equivalent features are now available
2275 using INVITE and BAN commands. Updated the protocol specs.
2277 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2278 in the network about change in the current ban list. The notify
2279 type is not used by the client.
2281 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2282 support the invite lists.
2284 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Added new function silc_string_regexify that converts string
2287 including wildcard characters into regex string that can
2288 be used by the GNU regex library. Added into the file
2289 lib/silcutil/silcutil.[ch].
2291 Added silc_string_regex_combine to combine to regex strings
2292 into one so that they can be used as one regex string by
2293 the GNU regex library. Added into the file
2294 lib/silcutil/silcutil.[ch].
2296 Added silc_string_regex_match to match two strings. It returns
2297 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2299 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Imported GNU regex to the soruce tree into lib/contrib.
2302 Fixed some compiler warning from the regex.c.
2304 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Fixed MOTD command in the server to work in router environment.
2308 * Fixed the MOTD command in the client library to support
2309 the server argument in the command.
2311 * Added `nickname_len' argument to the silc_idlist_add_client
2312 in the server, as the `nickname' argument may be binary data
2315 * Added silc_idlist_get_channels to return all channels from
2318 * Implemented LIST command to the server. Affected file is
2321 * Implemented the LIST command to the client library and on the
2324 * Added [<user count>] argument to the LIST command reply.
2325 With private channels the user count is not shown.
2327 * Updated TODO and README.
2329 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * The client entry's data.registered must be TRUE even with
2332 global client entry on global client list. The data.registered
2333 is used to check whether the client is anymore in the network,
2334 for example with WHOWAS command so it must be valid.
2336 * Fixed the WHOWAS command in the server. It now actually works
2337 in router environment. Added function into silcd/command_reply.c
2338 silc_server_command_reply_whowas_save.
2340 * Added silc_idlist_purge function to the silcd/idlist.c
2341 to periodically purge the ID Cache.
2343 * Fixed INFO command in the server. It works now in router
2344 environment. Added <server name> argument to the INFO command
2345 reply. Updated the protocol specs.
2347 * Fixed minor bug in silc_idcache_purge to not purge if the
2348 expire value is zero.
2350 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2351 they were buggy because of the WHOWAS information.
2353 * Fixed local command MSG to handle the async resolving of
2354 the remote client properly. It used to fail the first MSG.
2355 Affected file silc/local_command.c.
2357 * Added `data_len' field to SilcIDCache context.
2359 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Update TODO. Todo in commands in the server.
2363 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2366 used by routers as broadcast packet to inform other routers
2367 about the changed user mode.
2369 Implemented the notify handling in the server. Affected file is
2370 silcd/packet_receive.c. Added the function
2371 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2373 * Added new generic Channel Payload and deprecated the New Channel
2374 Payload. The New Channel Payload is now the generic Channel
2377 * Added new argument `mode' to the silc_server_send_new_channel
2378 as it is required in the Channel Payload now.
2380 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2381 and created a new and real SilChannelPayload to represent the
2382 new generic Channel Payload. Implemented the encode/decode
2383 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2385 * Added silc_server_get_client_channel_list to return the list
2386 of channels the client has joined for WHOIS command reply.
2387 Affected file silcd/server.[ch].
2389 * Implemented the channel list sending in the WHOIS command reply
2390 in server and in the client.
2392 Implemented the channel list displaying on the user interface
2393 as well. Affected file silc/client_ops.c.
2395 * Added silc_channel_payload_parse_list to parse list of Channel
2396 Payloads. It returns SilcDList list of SilcChannelPayloads.
2397 Client for example can use this function to parse the list of
2398 channels it receives in the WHOIS command reply. The caller
2399 must free the list by calling silc_channel_payload_list_free.
2400 Affected files lib/silccore/silcchannel.[ch].
2402 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Added one new argument <user mode> to the WHOIS command reply
2405 to return the mode of the user in SILC. Updated the protocol
2408 Implemented it to the server and client.
2410 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Fixed the mode printing on the user interface on joining.
2413 Affected file silc/client_ops.c.
2415 * Implemented the UMODE command and user modes in general to the
2416 client library and to the user interface.
2418 * Implemented the UMODE command to the server.
2420 * The server now sends UNKNOWN_COMMAND error status if client sends
2421 unknown command. Affected file silcd/command.c.
2423 * All server commands now handle the command identifier the right
2424 way when sending the command reply to the client. The client can
2425 use to identify the command replies with the identifier.
2427 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Added silc_server_get_client_route to resolve the route to
2430 the client indicated by the client ID. Affected file is
2433 * Added silc_server_relay_packet as general function to relay
2434 packet to arbitrary destination. This deprecates functions
2435 like _send_private_message_key, _relay_notify etc. Affected
2436 file is silcd/packet_send.[ch].
2438 Removed silc_server_send_key_agreement,
2439 silc_server_send_private_message_key and
2440 silc_server_packet_relay_notify functions from the file
2441 silcd/packet_send.[ch].
2445 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2446 server. Affected file silcd/packet_receive.[ch].
2448 * Implemented the KILL command to the client. Implemented the
2449 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2450 Affected files lib/silcclient/command[_reply].c and
2451 lib/silcclient/client_notify.c. Implemented the KILL notify
2452 printing in the user inteface.
2454 * Fixed a lot silc_parse_nick memory leaks from the client
2455 library in the file lib/silcclient/command.c.
2457 * Changed the silc_server_send_notify_on_channels's `sender'
2458 argument from SilcSocketConnection to SilcClientEntry to
2459 check the sender as entry and not as connection object and not
2460 to send to the client provided as argument. The affected file
2461 is silcd/packet_send.[ch].
2463 * The notify packets that are destined directly to the client used
2464 to not to be processed by the server. Now changed that and the
2465 server processes all notify packets. After relaying the packet
2466 to the client the notify packet is processed in the server.
2468 * The silc_server_free_client_data now checks whether there is
2469 pending outgoing traffic for the client and purges the data to
2470 the network before removing the client entry.
2472 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2475 an client is killed from the SILC Network. Updated the protocol
2478 Added new function silc_server_send_notify_killed to the
2479 silcd/packet_send.[ch].
2481 * Added function silc_server_packet_relay_notify to relay notify
2482 packets that are destined directly to a client. In this case
2483 the server does not process the notify packets but merely relays
2484 it to the client. Affected file silcd/packet_send.[ch].
2486 Added also silc_server_packet_process_relay_notify to check
2487 whereto relay the notify. Affected file is
2488 silcd/packet_receive.[ch].
2490 * Implemented the KILL command to the server.
2494 * Added the backup schema desgined last fall to the protocol
2495 specs for everyone to see. The specification is in the
2496 *-spec-xx.txt draft and the packet type definitions for the
2497 backup routers is in *-pp-xx.txt draft. Thusly, added also
2498 new packet type SILC_PACKET_CELL_ROUTERS.
2500 * A big security problem in the implementation discovered. The
2501 signoff of an client did not cause new channel key generation
2502 which it of course should've done. The channel keys must be
2503 always re-generated when client leaves (or signoffs) the channel.
2504 The silc_server_remove_from_channels funtion now handles
2505 the channel key re-generation.
2507 * Added `sender' argument to the silc_server_send_notify_on_channels
2508 to not to send the client provided as argument. Affected file
2509 silcd/packet_send.[ch].
2511 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2513 * Implemented OPER and SILCOPER commands into the server and
2516 * Added silc_auth_verify and silc_auth_verify_data to verify
2517 the authentication directly from the authentication payload.
2518 It supports verifying both passphrase and public key based
2519 authentication. Affected file lib/silccore/silcauth.[ch].
2521 * Added `hash' field to the SilcIDListData structure. It is the
2522 hash negotiated in the SKE protocol. Affected file is
2525 * Slight redesigning of the SilcAuthPayload handling routines.
2526 Do not send SilcPKCS but SilcPublicKey as argument.
2528 * Implemented the public key authentication support to the
2529 serverconfig. The public key is loaded from the provided path
2530 and saved as authentication data to void * pointer. Thus,
2531 changed the unsigned char *auth_data to void *auth_data;
2533 * Fixed SHUTDOWN command to send the reply before the server
2534 is shutdown. :) Affected file silcd/command.c.
2536 * Fixed fatal bug in CONNECT command. The hostname was invalid
2537 memory and server crashed. Affected file silcd/command.c.
2539 * Fixed fatal bug in CLOSE command. The server_entry became
2540 invalid but was referenced later in the command. Affected file
2543 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Fixed fatal bug in failure packet handling. Server ignored
2546 the failure and thus crashed when it came.
2550 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2553 that the command may be executed only once in (about) 2 seconds.
2554 The old SILC_CF_LAG flag is same but allows command bursts up
2555 to five before limiting.
2557 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2558 server code. Various commands now includes the CF_LAG_STRICT
2559 flag to disallow any kind of miss-use of the command.
2561 * Fixed the silc_buffer_unformat to not to allocate any data
2562 if the length of the data is zero. It used to allocate the
2563 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2565 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Changed the format of AdminConnection configuration section
2568 in the server. Added username of the admin to the format.
2569 Affected files silcd/serverconfig.[ch].
2571 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2572 to return admin configuration data by host, username and/or
2575 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Implemented WHOWAS command to the server. Added the functions:
2579 silc_server_command_whowas_parse,
2580 silc_server_command_whowas_send_reply,
2581 silc_server_command_whowas_from_client and
2582 silc_server_command_whowas_from_server
2584 * Added <Client ID> argument to the WHOWAS command reply. Updated
2585 the protocol specs accordingly.
2587 * Implemented WHOWAS command and command_reply to the client
2590 Implemented the WHOWAS printing on the user interface.
2592 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Added new argument to the WHOWAS command reply, the real name.
2595 It is an optional argument. Updated the protocol specs.
2597 * Added SilcIDCacheDestructor callback that is registered when
2598 the SilcIDCache is allocated. The callback is called when
2599 an cache entry in the ID Cache expires, or is purged from the
2600 cache. Added into lib/silccore/idcache.[ch].
2602 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2603 to destruct the client entries when the cache entry expires.
2604 Other ID Cache's in server and in the client library ignores
2607 * If the ID Cache entry's `expire' field is zero then the entry
2608 never expires. Added boolean `expire' argument to the
2609 silc_idcache_add function in the lib/silccore/idcache.[ch].
2610 If it is TRUE the default expiry value is used.
2612 * Added silc_server_free_client_data_timeout that is registered
2613 when client disconnects. By default for 5 minutes we preserve
2614 the client entry for history - for WHOWAS command.
2616 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Added support to the server to enforce that commands are not
2619 executed more than once in 2 seconds. If server receives
2620 commands from client more frequently, timeout is registered
2621 to process the commands. Affected file silcd/command.c.
2622 Added new function silc_server_command_process_timeout.
2624 * Changed NICK_NOTIFY handling in client library to check that
2625 if the client's nickname was changed, so there is no need to
2626 resolve anything from the server.
2628 * Removed error printing from the WHOIS and IDENTIFY commands.
2629 If error occurs then it is ignored silently in the client library.
2630 The application, however, may map the received error to
2631 human readable error string. The application currently maps
2632 the NO_SUCH_NICKNAME error to string.
2634 * Made the command status message public to the application. Moved
2635 them from lib/silcclient/command_reply.c to
2636 lib/silcclient/command_reply.h. The application can map the
2637 received command status to the string with the
2638 silc_client_command_status_message function.
2640 * Added check to the server to check that client's ID is same
2641 as the Source ID in the packet the client sent. They must
2644 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Added dist-bzip hook to the Makefile.am to make bzip2
2647 compressed distributions.
2649 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Server now enforces the maximum length for the nickname and
2652 the channel as protocol specification dictates. 128 bytes for
2653 nickname and 256 bytes for channel name.
2655 * Moved the WHOIS printing to the application. The client libary
2656 does not print out the WHOIS information anymore, the application
2657 must do it. Renamed silc_client_command_reply_whois_print to
2658 the silc_client_command_reply_whois_save.
2660 The client's idle time is also sent to the application now, and
2661 the idle is shown on screen.
2663 * Added silc_client_command_reply_identify_save to save the
2664 received IDENTIFY entries.
2666 * Do not check for channel private keys in message sending and
2667 reception if the channel does not have the PRIVKEY mode set.
2668 Affected file lib/silclient/client_channel.c.
2670 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2673 just surfaced after chaning the JOIN procedure.
2675 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Added silc_client_get_clients_by_list to get client entries
2678 from Client ID list, that is returned for example by JOIN
2679 and USERS command replies. The application should use this
2680 function for example when JOIN command reply is received to
2681 resolve the clients already on the channel (library does not
2682 do that anymore as USERS command reply is not used in the JOIN
2683 procedure anymore). Affected files lib/silcclient/silcapi.h and
2684 lib/silcclient/idlist.c.
2686 * JOIN command reply and USERS command reply returns now SilcBuffer
2687 pointers instead of unsigned char pointers when returning
2688 the client list and mode list.
2690 * Added <Client ID> argument to the JOIN command reply, mainly
2691 for the server to identify for which client the command was
2692 originally sent. Updated protocol specs accordingly.
2694 * Added SilcDlist private_key pointer to the SilcChannelEntry
2695 in the client to support the channel private keys. Affected
2696 file is lib/silcclient/idlist.h.
2698 * Added SilcChannelPrivateKey argument to the function
2699 silc_client_send_channel_message so that application can choose
2700 to use specific private ke if it wants to. If it is not provided,
2701 the normal channel key is used, unless private keys are set.
2702 In this case the first (key that was added first) is used
2703 as the encryption key.
2705 * Implemented the support for channel private key handling.
2706 Implemented the following functions:
2708 silc_client_add_channel_private_key,
2709 silc_client_del_channel_private_keys,
2710 silc_client_del_channel_private_key,
2711 silc_client_list_channel_private_keys and
2712 silc_client_free_channel_private_keys
2714 Affected file lib/silcclient/client_channel.c.
2716 * Added the support for the private keys in the channel message
2717 sending and encryption and in the message reception and
2718 decryption. Affected funtions are
2719 silc_client_send_channel_message and silc_client_channel_message.
2721 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added SKE's key verify callback to the client library's
2724 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2726 * Removed the statement that server (or router) must send USERS
2727 command reply when joining to the channel so that the client
2728 knows who are on the channel. Instead, the client list and
2729 client's mode list is now sent in the JOIN command reply to the
2730 client who joined channel. This is better solution.
2732 * Added function silc_server_get_users_on_channel and function
2733 silc_server_save_users_on_channel to the silcd/server.[ch].
2735 * Removed function silc_server_command_send_users from the
2738 * Do not show topic on the client library anymore. The topic is
2739 sent in the command reply notify to the application and the
2740 application must show the topic now.
2742 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Added client searching by nickname hash into the IDENTIFY and
2745 WHOIS commands in the server as they were clearly missing from
2746 them. Affected file is silcd/command.c.
2748 * Fixed a bug in private message receiving in the client library.
2749 The remote ID was freed and it wasn't supposed, now it is
2752 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Minor fix to the channel payload; allocate the data area, as it
2755 needs to be of specific length.
2757 * If the key agreement port is zero then the operating
2758 system will define the bound port. Affected files are
2759 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2761 * Added new function silc_channel_payload_decrypt into the file
2762 lib/silccore/silcchannel.[ch].
2764 * Moved the channel message etc, check from silc_packet_decrypt
2765 to applications. The library calls now a generic
2766 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2767 when the packet is either normal or special. This was done to
2768 allow more wide range of checking that was not allowed when
2769 the code was in library. Now applications can do virtually any
2770 checks to the packet and return to the library the decision how
2771 the packet should be processed. Affected files are
2772 lib/silccore/silcpacket.[ch].
2774 Added silc_server_packet_decrypt_check to the server and
2775 silc_client_packet_decrypt_check to the client library.
2777 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2778 to send with specified source and destination information.
2780 * Channel message delivery between routers was broken after the
2781 channel key distribution was fixed earlier. The channel key
2782 was used be to distributed to other routers as well which is not
2783 allowed by the protocol. Now this is fixed and channel keys
2784 really are cell specific and the channel message delivery between
2785 routers comply with the protocol specification.
2787 * Fixed various commands in server to check also the global list
2788 for the channel entry and not just the local list. The affected
2789 file silcd/command.c.
2791 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Added assert()s to buffer formatting and unformatting routines
2794 to assert (if --enable-debug) when error occurs. Affected
2795 file: lib/silcutil/silcbuffmt.c.
2797 * Changed to auto-reconnect to check whether the remote host is
2798 router and register the re-connect timeout if it is. It used
2799 to check that whether we are normal server, but router must do
2800 auto-reconnect with another router as well. Affected file
2803 * Removed the [<key len>] option from CMODE command as the cipher
2804 name decides the key length, nowadays. See the defined ciphers
2805 from the protocol specification.
2807 * Added [<hmac>] option to the CMODE command to define the HMAC
2808 for the channel. Added SILC_CMODE_HMAC channel mode.
2810 * Added [<hmac>] option for the JOIN command so that user can
2811 select which HMAC is used to compute the MACs of the channel
2814 * Added Hmac field to the Channel Message Payload. The integrity
2815 of plaintext channel messages are now protected by computing
2816 MAC of the message and attaching the MAC to the payload. The
2817 MAC is encrypted. Now, it is clear that this causes some
2818 overhead to the size of the packet but rationale for this is that
2819 now the receiver can verify whether the channel message decrypted
2820 correctly and also when private keys are set for the channel the
2821 receiver can decrypt the packet with several keys and check from
2822 the MAC which key decrypted the message correctly.
2824 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2825 lib/silccrypt/silccipher.[ch].
2827 * Added silc_hash_len to return the digest length into the
2828 lib/silcrypt/silchash.[ch].
2830 * Rewrote parts of Silc Channel Payload interface in the
2831 lib/silccore/silcchannel.[ch]. The encode function now also
2832 encrypts the packet and parse function decrypts it.
2834 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Fixed a minor formatting bug in the SKE's key material processing.
2837 It actually might have processed the keys wrong way resulting
2840 * Redefined the mandatory HMAC algorithms and added new algorithms.
2841 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2842 and hmac-md5 truncated to 96 bits. The mandatory is now
2843 hmac-sha1-96. Rest are optional (including the one that used
2844 to be mandatory). Rationale for this is that the truncated HMAC
2845 length is sufficient from security point of view and can actually
2846 make the attack against the HMAC harder. Also, the truncated
2847 HMAC causes less overhead to the packets. See the RFC2104 for
2850 * Added new [hmac] configuration section. The SKE used to use
2851 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2852 is of course wrong. The official names that must be proposed in
2853 the SKE are the ones defined in the protocol specification
2854 (hmac-sha1-96 for example). The user can configure any hmac
2855 using any hash function configured in the [hash] section. At
2856 least, the mandatory must be configured.
2858 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2860 * Added HMAC list to the SKE proposal list. It has now both
2861 hash algorithm list and HMAC list. This makes the protocol
2862 incompatible with previous versions. The SKE now seems to work
2863 the way it is supposed to work, for the first time actually.
2865 * Defined plain Hash algorithms to the protocol specification.
2868 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Implemented support for key agreement packets into the server.
2871 Added functions silc_server_key_agreement and
2872 silc_server_send_key_agreement. Other than these functions,
2873 server has nothing to do with this packet.
2875 * Added support for private message key packets into the server.
2876 Added functions silc_server_private_message_key and
2877 silc_server_send_private_message_key.
2881 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2882 called in the protocol's final callback instead in the END
2883 protocol state. This makes a little more sense and in the same
2884 time in client we can use the same protocol routines for normal
2885 key exchange and to key agreement packet handling as well.
2887 * Added to both client's and server's KE protocol context the
2888 SilcSKEKeyMaterial pointer to save the key material. We will
2889 bring the key material to the protocol's final callback by doing
2890 this. The final callback must free the key material.
2892 * Added SKE's packet_send callback into client's KE protocol
2893 context so that the caller can choose what packet sending function
2894 is used. This way we can use different packet sending when
2895 doing normal SKE when doing key agreement packet handling (in
2896 the key agreement packet handling we do not want to encrypt
2899 * Implemented the responder side of the key agreement routines
2900 in the client. The client can now bind to specified port and
2901 accept incoming key negotiation. The key material is passed
2902 to the application after the protocol is over.
2904 * Implemented the processing of incoming Key Agreement packet
2905 in the client. Added function silc_client_key_agreement to
2908 * Implemented the intiator side of the key agreement routines
2909 in the client. The client can now initiate key agreement with
2910 another remote client. The key material is passed to the
2911 application after the protocol is over.
2913 * Created client_keyagr.c to include all the key agreement
2916 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2917 SILC_TASK_CALLBACK except that it is not static.
2919 * Created client_notify.c and moved the Notify packet handling
2920 from the client.[ch] into that file.
2922 * Created client_prvmsg.c and moved all private message and
2923 private message key routines from the client.[ch] into that file.
2925 * Create client_channel.c and moved all channel message and
2926 channel private key routines from the client.[ch] into that file.
2928 * Changed silc_client_get_client_by_id_resolve to resolve with
2929 WHOIS command instead of IDENTIFY command, in the file
2930 lib/silclient/idlist.c.
2932 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Implemented the SKE's responder side to the Client library.
2936 * When FAILURE is received to the protocol do not trust it
2937 blindly. Register a timeout to wait whether the remote closes
2938 the connection as it should do it, only after that process the
2939 actual failure. This was changed to both client and server.
2941 * Added client_internal.h to include some of the structures
2942 there instead of client.h in lib/silcclient/.
2944 * Added function silc_task_unregister_by_callback to unregister
2945 timeouts by the callback function.
2947 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Some "Incomplete WHOIS info" errors has been appearing on the
2950 log files. Took away the entry->userinfo check from WHOIS
2951 reply sending. The entry->userinfo is now " " if client did not
2952 provide one. I thought this was fixed earlier but something
2953 is wrong still. Let's see if the error still appears.
2955 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Fixed a minor bug in the login when the channel key is
2958 re-generated in the server. It used to generate the key in
2959 wrong order and thus caused problems in the channel traffic.
2961 * Fixed a minor bug in channel key distsribution after
2962 KICK command. The key was not sent to the router even though
2965 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Added silc_ske_process_key_material_data as generic routine
2968 to process any key material as the SILC protocol dictates. The
2969 function is used by the actual SKE library but can be used by
2970 applications as well. This relates to the private message keys
2971 and the channel private keys since they must be processed the
2972 same way the normal SILC session keys. The protocol dictates
2973 this. Affected files: lib/silcske/silcske.[ch].
2975 Added also silc_ske_free_key_material to free the
2976 SilcSKEKeyMaterial structure.
2978 * Defined silc_cipher_set_key function to set the key for
2979 cipher without using the object's method function. The affected
2980 files: lib/silccrypt/silccipher.[ch].
2982 * Implemented silc silc_client_add_private_message_key,
2983 silc_client_add_private_message_key_ske,
2984 silc_client_del_private_message_key,
2985 silc_client_list_private_message_keys and
2986 silc_client_free_private_message_keys functions in the
2989 Added functions silc_client_send_private_message_key to send
2990 the Private Message Key payload and silc_client_private_message_key
2991 to handle incoming Private Message Key payload.
2993 * Added Cipher field to the Private Message Key payload to set
2994 the cipher to be used. If ignored, the default cipher defined
2995 in the SILC protocol (aes-256-cbc) is used.
2997 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Removed lib/silcclient/ops.h file.
3001 Redefined parts of the SILC Client Library API. Created new
3002 file silcapi.h that deprecates the ops.h file and defines the
3003 published Client Library API. Defined also private message key
3004 API and channel private key API into the file.
3006 This is the file that the application must include from the
3007 SILC Client Library. Other files need not be included by
3008 the application anymore.
3010 * Added new key_agreement client operation callback and also
3011 defined the Key Agreement library API for the application.
3013 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3016 is used by clients to request key negotiation between another
3017 client in the SILC network. If the negotiation is started it
3018 is performed using the SKE protocol. The result of the
3019 negotiation, the secret key material, can be used for example
3020 as private message key.
3022 Implemented the Key Agreement payload into the files
3023 lib/silccore/silauth.[ch].
3025 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Redefined ciphers for the SILC protocol. Added some new ciphers
3028 and defined the key lengths for the algorithms. Changed the
3029 code accordingly. The default key length is now 256 bits.
3031 * Fixed SKE key distribution function silc_ske_process_key_material
3032 when the key length is more than 128 bits. The default key
3033 length in SILC is now 256 bits.
3035 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3036 to indicate unsupported algorithm.
3038 * Renamed rijndael.c to aes.c and all functions as well.
3040 * Fixed a long standing channel key setting bug in client library.
3041 Weird that it has never surfaced before.
3043 * Fixed bug in channel deletion. If the entire channel is removed
3044 then it must also delete the references of the channel entry
3045 from the client's channel list as the client's channel entry and
3046 the channel's client entry share same memory.
3048 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Implemented CONNECT and SHUTDOWN commands in the client.
3052 * Implemented CLOSE command to the client.
3054 * Added the function silc_idlist_find_server_by_name into the
3055 files silcd/idlist.[ch].
3057 Added the function silc_idlist_find_server_by_conn into the
3058 files silcd/idlist.[ch].
3060 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * DIE command was renamed to SHUTDOWN. Updated the both code
3065 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3066 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3068 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3071 * Added function silc_server_create_connection function to create
3072 connection to remote router. My server implementation actually
3073 does not allow router to connect to normal server (it expects
3074 that normal server always initiates the connection to the router)
3075 so the CONNECT command is only good for connecting to another
3078 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3081 or some other client was kicked from the channel.
3083 Implemented the handling of the notify type to both client
3086 Implemented silc_server_send_notify_kicked to send the KICKED
3087 notify. It is used to send it to the server's primary router.
3089 * Implemented the KICK command into server and client.
3091 * Added `query' argument to the silc_idlist_get_client function
3092 to indicate whether to query the client from server or not if
3095 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3096 to indicate that the client is not channel founder.
3100 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Removed the rng context from SilcPacketContext structure and
3103 changed that the packet routine uses the Global RNG API.
3105 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Added support for quit message that client can "leave" on the
3108 channel when it quits the SILC. It is ditributed inside the
3109 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3111 Added silc_server_free_client_data that will take the
3112 signoff message as argument.
3114 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3116 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Updated parts of the protocol specification to keep it up
3121 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3124 payloads in one packet.
3126 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3127 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3128 use now the new List flag.
3130 * Also deprecated the following packet types: REPLACE_ID,
3131 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3133 * Added list support for Notify packet in server.
3135 * Added silc_server_send_notify_channel_change to send the
3136 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3137 the silc_server_send_replace_id.
3139 * Added silc_server_send_notify_nick_change to send the
3140 NICK_CHANGE notify type. Deprecates the function
3141 silc_server_send_replace_id.
3143 * Added silc_server_send_notify_join to send the JOIN notify type.
3144 Deprecates the function silc_server_send_new_channel_user.
3146 * Added silc_server_send_notify_leave to send LEAVE notify type.
3147 Deprecates the function silc_server_send_remove_channel_user.
3149 * Added silc_server_send_notify_cmode and
3150 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3151 types. Deprecates the silc_server_send_set_mode function.
3153 * Added SERVER_SIGNOFF notify type to indicate that server has
3154 quit. This means that all clients on the channel from that
3155 server will drop. This can be also used when netsplit happens.
3157 Deprecated REMOVE_ID packet type since it is not needed anymore
3160 Added silc_server_send_notify_server_signoff to send the
3161 SERVER_SIGNOFF notify type. Deprecates the function
3162 silc_server_send_remove_id.
3164 Added also silc_server_send_notify_signoff to send the
3165 SIGNOFF notify type.
3167 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3168 SILC protocol from this day on. Changed the protocol
3169 specification as well.
3171 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3172 notify type. It is used between routers to notify about
3173 topic changes on a channel.
3175 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3178 * Partly updated the protocol specification to comply with the
3179 changes now made. It is still though a bit outdated.
3181 * The JOIN notify type now takes one extra argument <Channel ID>.
3182 The packet used to be destined to the channel but now the
3183 JOIN type may be sent as list thus it is impossible to
3184 destine it to any specific channel. By adding this argument
3185 it is again possible.
3187 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Added CREDITS file. The CHANGES and CREDITS file will appear
3190 in the distribution as well.
3192 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3195 types in the server's silcd/packet_receive.c.
3197 * Implemented CMODE and CUMODE to work in router environment.
3199 * Fixed minor encoding and decoding buglet from the
3200 lib/silccore/silcmode.c.
3202 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3205 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3207 * Changed all SilcConfigServer* and silc_config_server* to
3208 SilcServerConfig* and silc_server_config*, respectively.
3211 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Associated the ID (client or server ID) to the Authentication
3214 Payload to avoid any possibility of forging. Updated the
3215 protocol specification and the code accordingly.
3217 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * The RSA key length is now save to the RsaKey context in the
3220 key generation process in lib/silccrypt/rsa.c. The key length
3221 is now used to figure out the maximum size of the block allowed
3222 to be encrypted/signed.
3224 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3225 is equivalent to the silc_mp_mp2bin but does not allocate any
3228 * Changed silc_mp_mp2bin API to take length argument. If it is
3229 non-zero then the buffer is allocated that large. If zero, then
3230 the size is approximated using silc_mp_sizeinbase, which however
3233 * Created Global RNG API which is global RNG that application can
3234 initialize. After initializing, any routine anywhere in the
3235 code (including library) can use RNG without allocating a new
3236 RNG object. This was done to allow this sort of use of the
3237 RNG in code that has no chance to allocate RNG object. All
3238 applications currently allocate this and many routines in the
3239 library use this. Affected file lib/silccrypt/silcrng.[ch].
3241 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3242 it to use the Global RNG API.
3244 * Defined Authentication Payload into protocol specification that
3245 is used during SILC session to authenticate entities. It is
3246 used for example by client to authenticate itself to the server
3247 to obtain server operator privileges.
3249 Implemented this payload into the lib/silccore/silcauth.[ch].
3250 Implemented also routines for public key based authentication
3251 as the new protocol specification dictates.
3253 Moved definitions of different authentication methods from
3254 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3256 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3257 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3258 silc_pkcs_verify_with_hash functions into the file
3259 lib/silccrypt/silcpkcs.[ch].
3261 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * The client entry's userinfo pointer must be always valid.
3264 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3265 will fail since it requires the userinfo. Now, the userinfo
3266 is allocated as "" if actual userinfo does not exist. Actually,
3267 it must exist and it is totally Ok to drop client connections
3268 that does not announce the userinfo. However, we will make
3269 this workaround for now.
3271 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3272 to return the remote port by socket.
3274 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3277 SILC_SERVER_PENDING_EXEC and added an new macro
3278 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3279 data or when error occurs while processing the pending command.
3281 Added new argument `destructor' into silc_server_command_pending
3282 and to the SilcServerCommandPending object. This destructor is
3283 now called after calling the pending callback or if error occurs
3284 immediately. If error occurs the actual pending callback won't
3285 be called at all - only the destructor. The destructor may be
3286 NULL if destructor is not needed.
3288 All this applies for client library code as well. Similar
3289 changes were made there as well for the pending commands.
3291 In the client, the application must now allocate the
3292 SilcClientCommandContext with the silc_client_command_alloc
3295 * Added reference counter to the SilcServerCommandContext. Added
3296 function silc_server_command_alloc and silc_server_command_dup
3299 Same type of functions added to the client library for the same
3302 * Removed the cmd_ident from IDListData away since it is now
3303 global for all connections. It is the command identifier used
3304 in command sending and with pending commands. The affected file
3307 * Added reference counter to the SilcSocketConnection objecet to
3308 indicate the usage count of the object. The object won't be
3309 freed untill the reference counter hits zero. Currently only
3310 server uses this, and client ignores it. The client must be
3311 set to use this too later. The affected files are
3312 lib/silccore/silcsockconn.[ch]. Added also the function
3313 silc_socket_dup to increase the reference counter.
3315 This was mainly added because it is possible that the socket
3316 is removed underneath of pending command or other async
3317 operation. Now it won't be free'd and proper DISCONNECTING
3318 flags, etc. can be set to avoid sending data to connection that
3319 is not valid anymore.
3321 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3322 the connection. After that it sets SILC_SET_DISCONNECTED.
3323 It is, however, possible that the socket data is not still freed.
3324 The silc_server_packet_process now checks that data is not
3325 read or written to connection that is DISCONNECTED. The socket
3326 get's freed when the reference counter hits zero.
3328 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Changed the client operation API: channel_message operation's
3331 `sender' is now the client entry of the sender, not the nickname
3332 and the `channel' is the channel entry, not the channel name.
3334 In the private_message operation the `sender' is now also the
3335 client entry of the sender not the nickname.
3337 Affected file is lib/silcclient/ops.h and all applications
3338 using the client operations.
3340 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Moved the calling of ops->connect() from connect_to_server_final
3343 into receive_new_id functin since that is the point when the
3344 client is actually allowed to send traffic to network. The
3345 affected file is lib/silcclient/client.c.
3347 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3350 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3351 (if needs broadcasting) instead of broadcasting the packets one
3352 by one which would make a burst in the network traffic.
3354 * Added `broadcast' argument to the functions in silcd/server.[ch]
3355 silc_server_create_new_channel[_with_id] to indicate whether
3356 to send New Channel packet to primary router.
3358 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Added new function into the silcd/server.[ch] files:
3361 silc_server_create_new_channel_with_id to create new channel with
3362 already existing Channel ID.
3364 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3365 lib/silccore/silcpacket.h. This packet is used t send list of
3366 Set Mode payloads inside one packet. Server uses this to set
3367 the modes for the channels and clients on those channels, that it
3368 announced to the router when it connected to it. The protocol
3369 specification has been updated accordingly.
3371 * The silc_server_new_channel did not handle the packet coming
3372 from normal server as it normally does not send that. However,
3373 when it announces its channels it does send it. Implemented
3374 the support for that.
3376 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3377 into the file lib/silccore/id.h.
3379 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Fixed memory leaks in the functions silc_idlist_del_client,
3382 silc_idlist_del_channel and silc_idlist_del_server in the file
3383 silcd/idlist.c. All of those leaked like a sieve.
3385 * Fixed some small memory leaks in the client's function
3386 silc_client_notify_by_server.
3388 * Added functions into silcd/server.c: silc_server_announce_clients,
3389 silc_server_announce_channels and silc_server_announce_server.
3390 These functions are used by normal and router server to announce
3391 to its primary router about clients, channels and servers (when
3392 router) that we own. This is done after we've connected to the
3395 These functions effectively implements the following packet types:
3396 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3397 and SILC_PACKET_NEW_ID_LIST.
3399 * Added new functions into the silcd/packet_receive.[ch]:
3400 silc_server_new_id_list, silc_server_new_channel_list and
3401 silc_server_new_channel_user_list to handle the incoming
3402 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3404 * Added support of changing Channel ID in the function
3405 silc_server_replace_id. If the server that announces a channel
3406 to the router already exists in the router (with same name but
3407 with different Channel ID), router is responsible to send
3408 Replace ID packet to the server and force the server to change
3409 the Channel ID to the one router has.
3411 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3412 client that the Channel ID has been changed by the router. The
3413 normal server sends this to the client. Client must start using
3414 the new Channel ID as the channel's ID.
3416 Implemented handling of this new type into lib/silcclient/client.c
3417 into the function silc_client_notify_by_server.
3419 * Added new function silc_idlist_replace_channel_id into the files
3420 silcd/idlist.[ch] to replace the Channel ID.
3422 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Call silc_server_command_identify_check always when processing
3425 the IDENTIFY command in silcd/command.c
3427 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3430 send keepalive packets. The packet can be sent by clients,
3431 servers and routers.
3433 Added function silc_socket_set_heartbeat into the file
3434 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3435 If not set, the heartbeat is not performed. The actual
3436 heartbeat is implemented in the low level socket connection
3437 library. However, application is responsible of actually
3440 Added silc_server_send_heartbeat to send the actual heartbeat
3441 packet into silcd/packet_send.[ch]. Server now performs
3442 keepalive with all connections.
3444 * Added silc_task_get_first function into lib/silcutil/silctask.c
3445 to return the timeout task with shortest timeout. There was a bug
3446 in task unregistration that caused problems. TODO has been
3447 updated to include that task system must be rewritten.
3449 * The client library will now resolve the client information when
3450 receiving JOIN notify from server for client that we know but
3451 have incomplete information.
3453 * Rewrote parts of silc_server_remove_from_channels and
3454 silc_server_remove_from_one_channel as they did not remove the
3455 channel in some circumstances even though they should've.
3457 * Encryption problem encountered in server:
3459 The LEAVE command used to send the Channel Key packet to the
3460 router immediately after generating it. However, the code
3461 had earlier sent Remove Channel user packet but not immediately,
3462 ie. it was put to queue. The order of packets in the router
3463 was that Channel Key packet was first and Remove Channel User
3464 packet was second, even though they were encrypted in the
3465 reverse order. For this reason, MAC check failed. Now, this
3466 is fixed by not sending the Channel Key packet immediately but
3467 putting it to queue. However, this is more fundamental problem:
3468 packets that are in queue should actually not be encrypted
3469 because packets that are sent immediately gets encrypted
3470 actually with wrong IV (and thus MAC check fails). So, packets
3471 that are in queue should be encrypted when they are sent to
3472 the wire and not when they put to the queue.
3474 However, the problem is that the current system has not been
3475 designed to work that way. Instead, the packet is encrypted
3476 as soon as possible and left to the queue. The queue is then
3477 just purged into wire. There won't be any fixes for this
3478 any time soon. So, the current semantic for packet sending
3481 o If you send packet to remote host and do not force the send
3482 (the packet will be in queue) then all subsequent packets to the
3483 same remote host must also be put to the queue. Only after the
3484 queue has been purged is it safe again to force the packet
3487 o If you send all packets immediately then it safe to send
3488 any of subsequent packets through the queue, however, after
3489 the first packet is put to queue then any subsequent packets
3490 must also be put to the queue.
3492 Follow these rules and everything works fine.
3494 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Added new function silc_server_remove_clients_by_server to
3497 remove all client entries from ID list when the server connection
3498 is lost. In this case it is also important to invalidate all
3499 client entires as they hold the invalid server entry. This
3500 fixes fatal bug when server has lost connection and will reconnect
3503 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Made some sanity checks to silc_server_daemonise like to check
3506 whether the requested user and group actually exists.
3508 * Added sanity check to SKE's silc_ske_responder_finish to check
3509 that the public and private key actually is valid.
3511 * Invalidate the client's nickname when receiving Replace ID
3512 packet and the Client ID is being replaced. This means that the
3513 server will query the nickname if someone needs it (client)
3516 * Sort the ID Cache in client library when the ID Cache data
3517 has changed (needs sorting).
3519 * Do not allow for SILC client to create several connections to
3520 several servers. The client does not support windows right now
3521 and generating multiple connections causes weird behaviour.
3523 Irssi-silc client does support windows and can handle several
3524 connections without problems, see: www.irssi.org and SILC plugin.
3526 * Fixed some places where client was added to the IDList. The
3527 rule of thumb is following (in order to get everything right):
3528 If the client is directly connected local client then the
3529 `connection' argument must be set and `router' argument must be
3530 NULL to silc_idlist_add_client function. If the client is not
3531 directly connected client then the `router' argument must
3532 bet set and the `connection' argument must be NULL to the
3533 silc_idlist_add_client function.
3535 * The funtion silc_server_packet_send_local_channel actually did
3536 not check whether the client was locally connected or not. It
3537 does that now. Fixed a bug related to LEAVE command.
3539 * Fixed Remove Channel User payload parsing bug in server's
3540 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3542 * The server's silc_server_save_channel_key now checks also the
3543 global ID list for the channel as it might not be in the local
3544 list. Fixed a bug related to LEAVE command.
3546 * Is this the end of the [<unknown>] buglet that has been lurking
3547 around for a long time? A little for loop fix in server's
3548 silc_server_command_whois_parse that is used by both IDENTIFY
3549 and WHOIS command. At least, this was a clear bug and a cause
3550 of one type of [<unknown>] buglet.
3552 * WHOIS and IDENTIFY commands call the function
3553 silc_server_command_[whois/identify]_check function even if
3554 we are not router server.
3556 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Added --with-gmp configuration option. If set the GMP
3559 is always compiled in the SILC source tree. If not set then
3560 it is checked whether the system has the GMP3 installed. If
3561 it has then the GMP won't be compiled (the system's headers
3562 and library is used), if it doesn't have it then the GMP is
3563 compiled in the SILC source tree.
3565 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Changed RSA private exponent generation to what PKCS #1
3568 suggests. We try to find the smallest possible d by doing
3569 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3570 not security fix but optimization.
3572 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added new config entry [Identity] to fork the server and run
3575 it as specific user and group. A patch from Bostik.
3577 * Imported Dotconf configuration library into lib/dotconf.
3578 This will be used to create the SILC configuration files later.
3579 It will appear in the distsribution after this commit.
3581 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * A big code auditing weekend happening. Auditing code for
3584 obvious mistakes, bugs and errors. Also, removing any code
3587 Removed files for being obsolete:
3589 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3590 inline in the file lib/silcutil/silcbuffer.h)
3592 o lib/silcutil/silcbufutil.c (the header has inline versions)
3594 Changed code to fix possible error conditions:
3596 o The buffer formatting routines now check that the destination
3597 buffer really has enough space to add the data. This applies for
3598 both buffer formatting and unformatting
3599 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3600 unformatting was changed to accomodate following rules:
3601 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3602 sent to the function while XXX_*STRING will not allocate or copy
3603 the data into the buffer. Instead it sets the pointer from the
3604 buffer into the pointer sent as argument (XXX_*STRING used to
3605 require that the pointer must be allocated already). This change
3606 makes this whole thing a bit more consistent and more optimized
3607 (note that the data returned in the unformatting with XXX_*STRING
3608 must not be freed now). The routines return now -1 on error.
3610 o Tried to find all code that use buffer_format and buffer_unformat
3611 and added return value checking to prevent formatting and
3612 especially unformatting errors and possible subsequent fatal
3615 o Changed ske->x and ske->KEY to mallocated pointers in
3616 lib/silcske/silcske.h. Fixed possible data and memory leak.
3618 o Added return value checking to all *_parse* functions. Fixed
3619 many memory leaks as well.
3621 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3622 so that buffer overflows would not happen. All code now also
3623 checks the return value as it can fail.
3625 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3627 * Added reconnection support to server if the normal server looses
3628 its connection to the router (for example if router is rebooted).
3629 The server performs normal reconnection strategy implemented
3630 to the server. Affected file silcd/server.c.
3632 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Added new packet type SILC_PACKET_SET_MODE that is used to
3635 distribute the information about changed modes (for clients,
3636 channels and clients channel modes) to all routers in the
3637 network. Updated the protocol specification accordingly.
3639 Added functions into silcd/packet_send.c and
3640 silcd/packet_receive.c: silc_server_send_set_mode,
3641 silc_server_set_mode.
3643 Added new files silcmode.[ch] into lib/silccore that implements
3644 the encoding and decoding of Set Mode Payload. Added new type
3645 SilcSetModePayload. Moved the definitions of different modes
3646 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3648 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Oops, a little mistake in server's connection authentication
3651 protocol. The protocol is not ended with FAILURE but with
3652 SUCCESS if the authentication is Ok. :) Affected file is
3655 * Implemented NICK_CHANGE notify handling in server in the file
3656 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3657 the local clients on the channel. After the changing nickname
3658 in router environment snhould work and the [<unknown>] nickname
3659 should appear no more.
3661 The silc_server_replace_id function that receives the Replace ID
3662 payload now sends the NICK_CHANGE notify type also in the file
3663 silcd/packet_receive.c
3665 * Changed WHOIS and IDENTIFY command to support the maximum amount
3666 of arguments defined in protocol specs (3328 arguments). This
3667 fixed a bug that caused problems when there were more than three
3670 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added extra parameter, command identifier, to the
3673 silc_client_send_command so that explicit command identifier
3676 Changed that ID list routines uses specific command identifier
3677 when sending WHOIS/IDENTIFY requests to the server so that they
3678 can be identified when the reply comes back.
3680 Affected files lib/silcclient/command.[ch],
3681 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3683 * Added `sender' argument to silc_server_packet_send_to_channel
3684 to indicaet the sender who originally sent the packet to us
3685 that we are now re-sending. Ignored if NULL. Affected file
3686 silcd/packet_send.[ch].
3688 * Added some server statistics support in silcd/server_internal.h
3689 SilcServerStatistics structure and around the server code. Also
3690 send some nice statistics information when client is connecting
3693 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Fixed channel ID decoding in server's JOIN command reply in
3696 silcd/command_reply.c
3698 * Fixed braodcasting of replace ID payload to not to send it if
3699 we are standalone server in silcd/packet_receive.c.
3701 * Fixed all channel message sending routines to not to send
3702 packets to clients that has router set, since they are routed
3703 separately in the same function earlier. Affects file
3704 silcd/packet_send.c and all channel packet sending functions.
3706 * In USERS reply, res_argv[i] are not allocated, the table
3707 is allocated. Thus changed that free the table, not its
3710 * In server's whois_check and identify_check if the client is
3711 locally connected do not send any WHOIS commands - they are not
3714 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed some minor bugs in client when sending WHOIS command. The
3717 arguments was in wrong order.
3719 * Removed statis function add_to_channel from server in
3720 silcd/command.c that was previously used with the joining but
3723 * Tested USERS command in router environment successfully with two
3724 routers, two servers and two clients.
3726 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Reorganized the USERS command and command reply in client library
3729 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3730 When the command is given by user we register a pending command
3731 callback that will reprocess the command after the reply has been
3732 received from the server. When reprocessing the packet we then
3733 display the information. Thus, the USERS information is displayed
3734 now in the command callback instead of in the command reply
3735 callback. The processing of the command is same as previously
3736 when server has sent the command reply in the JOINing process.
3738 * Added to USERS command in silcd/command_reply.c to join the client,
3739 we didn't use to know about, to the channel after we've created
3740 a client entry for it. Also, for clienet we did know already still
3741 check whether it is on the channel or not and add it if not.
3743 * Removed silc_server_command_join_notify as the function and its
3746 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Changed the client's pending command handling to the same as the
3749 server's pending command handling. It is also now possible to
3750 execute command reply functions from other command reply
3751 function as the function callbacks for commands and command
3752 replies are one and same. The pending commands are not static
3753 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3754 in client connection context. Thus, pending commands are server
3755 connection specific as it is convenient.
3757 Changed the function silc_client_command_pending and
3758 silc_client_command_pending_del and added new function
3759 silc_client_command_pending_check. Removed the
3760 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3763 * Added cmd_ident, current command identifier, to the client
3764 connection context in lib/silcclient/client.h to keep track on
3765 command identifiers used in command sending. Client's command reply
3766 function handling now supports the mandatory command identifiers.
3768 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3769 funtions in client to fully support pending command callbacks.
3771 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3772 as one of the arguments to the application in the command reply
3775 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3776 before first releasing SILC but came back. Now it is removed again
3777 and should come back nomore. The FORWARDED flag was used only
3778 by the JOINing procedure by forwarding the command packet to router.
3779 Now, the JOINing procedure has been changed to more generic (due
3780 to various router environment issues) and FORWARDED is not needed
3781 anymore for anything. The protocol specification is yet to be
3784 Now, removed silc_server_packet_forward from server and the flag
3785 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3787 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Renamed NAMES command to USERS command. The NAMES was named that
3790 due to historical reasons. Now it is renamed. Also, rewrote
3791 parts of the USERS command. The nickname list is not sent anymore
3792 by the server. Only Client ID and mode lists are sent in the USERS
3793 command. Changed this also to the protocol specification.
3795 The client now resolves the names and stuff after it receives
3796 the USERS list from the server when joining to the channel.
3798 * WHOIS and IDENTIFY commands has been changed to support multiple
3799 Client ID's per command. One can now search for multiple users
3800 in the network by sending only one WHOIS or IDENTIFY command.
3801 Changed the code and the protocol specifications.
3803 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3804 uses silc_server_command_whois_parse to parse the request. */
3806 * If normal server, do not parse the WHOIS and IDENTIFY requests
3807 before sending it to the router. Saves some time.
3809 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Fixed JOIN command on client library. Wrong number of arguments
3812 used to crash the client.
3814 * Added silc_server_channel_has_global function to check whether
3815 channel has global users or not.
3817 * Added silc_server_channel_has_local function to check whether channel
3818 has locally connected clients on the channel.
3820 * The silc_server_remove_from_one_channel now checks whether the
3821 channel has global users or not after given client was removed from
3822 the channel. It also checks whether the channel has local clients
3823 on the channel anymore. If it does not have then the channel entry
3824 is removed as it is not needed anymore.
3826 * The silc_server_notify now checks on JOIN notify whether the joining
3827 client is one of locally connected or global. If it is global then
3828 the channel has now global users on the channel and that is marked
3829 to the channel entry. Also, it now saves the global client to
3830 global list who is joining and JOINs it to the channel. This is
3831 for normal server, that is.
3833 Changed silc_server_send_notify_on_channel,
3834 silc_server_packet_relay_to_channel and
3835 silc_server_packet_send_to_channel check if we are normal server
3836 and client has router set (ie. global client) do not send the
3837 message to that client, as it is already routed to our router.
3839 * Implemented LEAVE notify type handling in silc_server_notify
3842 * Tested LEAVE command in router environment successfully. Tested
3843 with two routers, two servers and two clients.
3847 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3849 * Implemented SIGNOFF notify type handling in silc_server_notify
3852 * silc_server_remove_id now removes the client entry from all channels
3853 it has joined and thusly sends SIGNOFF notify type.
3855 * Rewrote the NAMES list generation in server by removing two excess
3856 loops. The lists are created now inside one loop.
3858 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * silc_server_remove_channel_user checks now also global list
3861 for channel and client.
3863 * silc_server_new_channel_user checks now both local and global
3864 list for channel and client. Fixed a bug in client id decoding.
3865 Used to decode wrong buffer.
3867 * silc_server_channel_message checks now both local and global
3868 list for channel entry.
3870 * Tested channel joining (hence JOIN) in router environment
3871 successfully. Tested with two routers, two servers and two
3874 * Tested channel message sending in router environment successfully.
3876 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Added silc_server_save_channel_key into server.[ch] to save the
3879 received channel key in Channel Key payload processing. It is
3880 also used in JOIN command reply handling.
3882 Equivalent function silc_client_save_channel_key added into
3883 client.[ch] into client library.
3885 * Changed JOIN command reply to send information whether the channel
3886 was created or not (is existing already) and the channel key
3887 payload. Changed protocol specs accordingly.
3889 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3890 the request was sent by ID and not by nickname. Crashed on
3893 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3896 now correctly save the received data.
3898 * silc_server_free_sock_user_data now notifies routers in the
3899 network about entities leaving the network.
3901 At the same time implemented functions silc_server_remove_id
3902 and silc_server_send_remove_id to receive and send REMOVE_ID
3903 packets. The packet is used to notify routers in the network
3904 about leaving entities. The ID removed will become invalid in
3907 * Added function silc_idlist_del_server into server. Removes and
3908 free's server entry from ID list.
3910 * silc_server_private_message function now checks, if we are router,
3911 that the destination ID really is valid ID, naturally.
3913 * In router when NEW_ID packet is received (for new client) the
3914 hash of the Client ID is saved in the ID Cache but the
3915 client->nickname is set to NULL, instead of putting the hash
3918 IDENTIFY command now also checks that client->nickname must be
3919 valid. If it is not if will request the data from the server who
3920 owns the client. Added new function
3921 silc_server_command_identify_check.
3923 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3924 to set the command to already allocated Command Payload.
3926 * Tested private message sending in router environment with two
3927 routers, two servers and two clients. Fixed minor bugs and now
3930 * Fixed segfault from client's NAMES command. Used to crash if
3933 * Forwarded packets must not be routed even if it is not destined
3934 to the receiver. Changed server code comply with this.
3936 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added `require_reverse_mapping' boolean value to ServerParams
3939 structure. If TRUE (not default) the server will require that
3940 the connecting host has fully qualified domain name.
3942 If the reverse mapping is not required and hostname could not be
3943 found the IP address is used as hostname.
3945 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Implemented version string checking to both client and server.
3948 The check is incomplete currently due to the abnormal version
3949 strings used in development version of SILC.
3951 * Changed all command functions in server to use the new
3954 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Changed char *data to unsigned char *data in ID Cache system to
3957 support binary data as ID Cache data. Changed code to support
3958 binary data in lib/silccore/idcache.c.
3960 * Renamed silc_server_packet_relay_command_reply to
3961 silc_server_command_reply as it is normal packet receiving
3962 function. Rewrote the function to accept command replys for
3963 servers and not only for clients.
3965 * Mark remote router always as registered server if we are connecting
3966 to it. Otherwise, commands sent by the router to us are ignored.
3968 * All ID List find routines now returns the ID Cache Entry pointer
3969 as well if requested.
3971 * WHOIS command works now in router environment, tested with two
3972 routers, two servers and two clients.
3974 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3975 in router environment (as it is almost equivalent to WHOIS) but
3976 hasn't been tested thoroughly. Added new functions:
3978 silc_server_command_identify_parse
3979 silc_server_command_identify_send_reply
3980 silc_server_command_identify_from_client
3981 silc_server_command_identify_from_server
3983 * Disabled route cache adding because adding two different ID's with
3984 same IP replaces the old cache entry thus giving wrong route.
3985 The entry->router->connection is always the fastest route anyway
3986 so route cache may not be needed. Of course, new routes maybe
3987 established after receiving the ID when the entry->router->connection
3988 might not be anymore the most optimal.
3990 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Add route cache for received ID for fast routing.
3994 * Added silc_server_packet_route to route received packet on router
3995 that is not destined to us.
3997 * Renamed silc_server_get_route to silc_server_route_get.
3999 * Added id_string and id_string_len fields into SilcServer to
4000 include encoded ServerID for fast comparing without excess
4001 encoding of the ID's.
4003 * Cleaned up WHOIS command on server side. Added following static
4006 silc_server_command_whois_parse
4007 silc_server_command_whois_check
4008 silc_server_command_whois_send_reply
4009 silc_server_command_whois_from_client
4010 silc_server_command_whois_from_server
4012 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4013 arguments in command replies. All command functions should be
4014 updated to use this macro.
4016 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Minor typo fixes on command reply handling on server.
4020 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Added silc_server_command_add_to_channel internal routine to add
4023 the client to the channel after router has created the channel and
4024 sent command reply to the server.
4026 * Added generic silc_server_send_command to send any command from
4029 * Use static buffer with ID rendering instead of duplicating data.
4031 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Fixed a channel user mode bug when joining to a channel server gave
4034 everybody channel founder rights, oops.
4036 * We mark ourselves as the router of the incoming server connection
4037 if we are router ourselves. This way we can check in some packet
4038 sending functions whether it is locally connected server. For
4039 incoming router connections we put NULL.
4041 * For router sending packets locally means now always sending the
4042 packet cell wide; to local clients and local servers. For normal
4043 server sending packet locally means sending it to only local
4046 * Fixed the JOIN command to really work in router environment. If the
4047 channel is created it is always created by the router. Router is
4048 also responsible of making the initial joining to the channel,
4049 sending JOIN notify to the sending server and distributing
4050 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4051 does not exist server doesn't do anything else but forward the
4052 command to the router which performs everything.
4054 * Added silc_server_send_channel_key function to send the Channel Key
4057 * Added silc_server_create_channel_key to create new channel key. The
4058 channel key is now re-generated everytime someone joins or leaves
4059 a channel, as protocol dictates. Note: channel->key_len is the
4062 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4065 packet_receive.[ch] to separate packet sending and receiving
4066 routines. The server.[ch] now includes everything else including
4067 actual packet processing (writing and reading data) and other
4070 Renamed silc_server_private_message_send_internal to
4071 silc_server_send_private_message. The routine is still though
4072 used only to relay private messages as server does not send
4073 private messages itself.
4075 Renamed silc_server_new_channel to silc_server_create_new_channel
4076 and added new function sicl_server_new_channel that handles the
4077 incoming New Channel packet. Added also new sending function
4078 silc_server_send_new_channel to send New Channel Payload.
4080 * Added new function silc_server_notify to process incoming notify
4081 packet to the server/router. Server may then relay the notify
4082 to clients if needed.
4084 * Added new function silc_server_new_channel_user to process incoming
4085 New Channel User packet. Router will redistribute the packet and
4086 send JOIN notify to its local clients and locally connected servers
4087 if needed. Normal server will send JOIN notify to its local client
4088 on same channel when received this packet. Added also corresponding
4089 sending function silc_server_send_new_channel_user to sent the
4092 * Added boolean route argument to send_notif_to_channel and
4093 packet_send_to_channel functions to attempt to route the packet
4094 if it is TRUE and send only locally if it is FALSE.
4096 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * silc_server_replace_id now broadcasts the received replace ID
4099 packet if it is not broadcast packet already. The router must
4100 broadcast to inform other routers about changed ID.
4102 * Added backpointer to server's router into SilcServer context in
4103 silcd/server_internal.h.
4105 * Fixed silc_server_packet_broadcast to send correct broadcast
4108 * The channel key is now distributed to the local client as soon
4109 as it is received from the router (in router environment) so that
4110 no other packet may be sent for the channel until client has
4113 * silc_server_remove_channel_user now broadcasts the received
4114 Remove Channel User packet if it is not broadcast packet already.
4115 The router must broadcast to inform other routers about removed
4118 * Added users field into SilcPacketContext that is a reference count
4119 of the context. One can increase the reference count by calling
4120 silc_packet_context_dup which is now changed to just increase the
4121 reference count instead of duplicating the data. The reference
4122 count is decresed by calling silc_packet_context_free that will
4123 free the data after the reference count hits zero.
4125 For now on the packet context and everything allocated into it
4126 (including the raw packet from network) must be freed by calling
4127 the new silc_packet_context_free function. Added also new function
4128 silc_packet_context_alloc that must be used now to allocate the
4129 context. This also means that if a routine is asynchronous from
4130 silc_[client/server]_packet_parse_type the packet context must
4131 be duplicated by calling silc_packet_context_dup. Otherwise it
4132 gets free'd after silc_[client/server]_packet_parse_type returns.
4133 Also, one must remember that if packet is duplicated then its
4134 reference count must be decresed by calling the free function as
4135 many times as it was duplicated.
4137 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4138 from both client and server.
4140 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Made joining to a channel working in router environment.
4144 * Cleaned up JOIN command on server side and create function
4145 silc_server_command_join_channel internal routine to make the
4148 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Changed silc_command_pending list to SilcDList. Also, added
4151 `ident' field to SilcServerCommandPending structure to identify
4152 the reply and to call correct callback.
4154 Added silc_server_command_pending_check function to replace the
4155 corresnponding macro. The silc_command_pending list is not
4158 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4159 to set identifier to previously allocated Command Payload. It
4160 is used to set identifier for command when resending Command
4163 * Added silc_command_payload_encode_payload to encode Command
4164 Payload buffer from SilcCommandPayload structure.
4166 * Added silc_argument_payload_encode_payload to encode Argument
4167 payload buffer from SilcArgumentPayload structure.
4169 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Changed WHOIS command to support router connection on server side.
4172 The whois request is always sent to router unless the server is
4173 standalone server. After server has received the reply from the
4174 router will it send the reply to the client.
4176 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4177 broadcast received broadcast packet. The function is used only
4178 by router. The broadcast packet is always sent to the router's
4181 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4182 render given ID to printable string, for log files for example.
4184 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Made basic router to router connections working. At least they
4187 can now connect to each other but nothing really works the way
4188 they are supposed - yet.
4190 * Added new initiator token to RouterConnection configuration
4191 file in silcd/serverconfig.[ch]. It is used to tell whether we
4192 are the initiator to the remote router or whether we'll expect
4193 the other end to connect.
4195 * Moved registering of listener task to silc_server_init, hence
4196 the server starts listenning as soon as it is run, even if it
4197 does not have connections to other routers. Let's see how well
4200 * Changed default connection retry timeouts for more suitable in
4203 * Removed cipher and such arguments from silc_idlist_add_client
4204 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4205 Added new function silc_idlist_add_data to add the keys and stuff
4208 * Added SilcIDListData structure and added it to SilcClientEntry
4209 and SilcServerEntry as their first field in the structure. This
4210 way we can explicitly cast the ID entries to the SilcIDListData
4211 structure and get common data for the entries. In past, we had
4212 to first check what type of connection it is and then cast it to
4213 correct ID entry type. Now, we can directly cast the opaque
4214 pointer to the SilcIDListData (no matter what ID entry it actually
4215 is) and get the data needed.
4217 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4220 in some circumstances even if threre were timeout tasks, though not
4221 IO tasks, but tasks anyway. Now fixed.
4223 * Defined SilcServerConnection structure to hold connection specific
4224 stuff about directly connected servers and routers. The definition
4225 is currently in silcd/server_internal.h. I thought about having
4226 a bit more important role fro this struct but for now it is used
4227 only when connecting to other server (or router actually).
4229 * Added connecting retry support in server when connecting to
4230 router(s). The retry feature implement exponential backoff
4231 algorithm. Also, added SilcServerParams structure to hold default
4232 parameters for server. For now, it include these retry settings
4233 and are hard coded. After server is moded to be as Silc Server
4234 Library this structure will be more important.
4236 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Changed client librarys channel->clients table to SilcList and
4239 changed code accordingly.
4241 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Changed client's channel table to SilcList and changed code
4244 accordingly. Also changed SilcChannelClientEntry to include back-
4245 pointer to the channel so that client entry can use that structure
4246 as list as well and we have fast cross-reference to the channel.
4247 This change dramatically decreased the complexity of channel
4248 handling with client entry and vice versa (removed one extra
4249 loop when searching for channel entry from many functions).
4251 * Changed server->sim from table to SilcDList and changed code
4254 * NAMES command can now be used from user interface. It will show
4255 the user list on the channel, neatly.
4257 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4258 Code now saves realname of the user if it becomes available.
4260 * Renamed configure.in to configure.in.pre and made ./prepare
4261 script to automatically add correct version string to
4262 configure.in which it creates from configure.in.pre.
4264 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * NAMES command reply now shows users mode with the nickname when
4269 * Moved silc_client_ch[u]mode[_char] functions from
4270 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4271 place sucks, they are utility functions and should be in some
4274 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4276 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4279 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Added TRQ (efficient deque and list library) into lib/trq. This is
4284 a very good list library that is currently used in the SILC. Defined
4285 SilcList API over the library because I didn't like the API very
4286 much. See lib/trq/silclist.h for the API and examples of how to
4287 use the API. Fixed various places in the code to use the new
4288 SilcList API. The SilcList is meant for lists that has a structure
4289 already defined as a list. It is not suitable to add just some
4290 context to the list (in TRQ, the context is the list actually).
4292 So, I defined SilcDList that can be used for the purpose where
4293 predefined list structure does not exit. This can be used as
4294 such list. Now some context just can be added to the SilcDList.
4295 Currently this list is not used in the SILC just yet, though there
4296 are a lot places where this can replace dynamically allocated
4297 tables and I will fix these places, later, to use SilcDList.
4298 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4299 and use TRQ internally).
4301 Also fixed some annoying warning messages that the original TRQ
4302 code generated. Also minor changes to TRQ's Makefile.in.
4304 * Added support for querying by Client ID to both WHOIS and
4305 IDENTIFY commands into server, as required by the protocol.
4307 * Removed method function pointers from SilcBuffer structure. They
4308 weren't used to anything and just increased the context size for
4309 no good reason. This change also made silc_buffer_alloc and
4310 silc_buffer_free functions inline functions.
4312 * Disabled command flooding detection support until it's fixed so
4313 that it accepts commands in but does not execute them more than once
4316 * Added silc_net_localhost(), to return local hostname, into
4317 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4318 that must be initialized before calling silc_client_init.
4320 * Added new function: silc_server_send_notify_on_channels to send
4321 notify messages to all channels client has joined. It is assured
4322 that the message is sent only once per client.
4324 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4325 lib/silcutil/silcutil.[ch] as silc_format function. The new
4326 function is generic and is used by server as well, not only by
4327 the logging routines.
4329 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4330 the provided version string was not acceptable. Added new function:
4331 silc_ske_check_version into lib/silcske/silcske.h. The function
4332 must be implemented by the application (client or server) and it
4333 does not reside in the SKE library. The function checks the version
4334 string remote end sent.
4336 * Added back pointers (to opaque context and to SilcSocketConnection)
4337 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4339 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4340 duplicate packet context structure.
4342 * Changed `notify' client operation to send same arguments as client
4343 receives from server except for ID's. ID's are mapped to correct
4344 ID entry and that is returned. Also, if channel entry is not sent
4345 by server but the notify is for channel the channel entry is sent
4346 to application (otherwise application doesn't know that it is for
4347 channel (library gets it from packet's Destination ID)).
4349 * Added silc_client_remove_from_channels into client library to
4350 remove a client from all channels it has joined to. Used when
4351 received SIGNOFF notify from server. Added also new function
4352 silc_client_replace_from_channels to replace old ID entry with
4353 new ID entry on all channels. Used when received NICK_CHANGE
4356 * Fixed ID Cache list handling in silc_idlist_get_client in
4357 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4358 to get (or query) client by ID.
4360 * Updated TODO list.
4362 * Added connection authentication status message defined by the
4363 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4364 support for these into the code in client and server side.
4366 * Added generic function silc_client_send_command to send any command
4367 with variable argument list. Application should use this function
4368 to send commands if the command functions provided by the library
4369 does not suite for the application's user interface needs.
4371 * Added new `failure' client operation. Application is notified about
4372 received failure packet if client is executing a protocol. In this
4373 case the protocol's execution has failed.
4375 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4376 is required by the protocol.
4378 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4379 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4382 * Added status flag to SilcSKE object to indicate realtime status
4383 of the SKE protocol.
4385 * Application receives now exactly same command reply arguments as
4386 the library receives from server. However, if ID is received the
4387 corresponding ID entry is returned to the application (eg. Client
4388 ID is mapped to correct SilcClientEntry entry and that is returned).
4389 Changed command_reply client operation due to this change.
4391 * Changed all ID's in commands and in command replys as ID Payloads.
4392 Change affected both client and server side codes.
4394 All ID's sent in SILC network (with execption of ID's in SILC
4395 Packet header) are sent in ID Payload to support variable length
4398 * Server now notifies nick changes and notifies all clients on
4399 the channels about the new nickname (about the new Client ID,
4402 * Implemented CMODE command to change channel modes. Supports all
4403 channel modes defined by the protocol specs except ban and invite
4404 lists. (Also, private channel key mode is supported but support for
4405 setting private channel key in client is missing, thus, this mode
4406 has no effect on client side (except that server requires that the
4407 client uses private channel key and normal channel traffic does not
4410 Also, invite mode works per se, but INVITE command does not work
4411 yet correctly, so you can set channel as invite only channel but
4412 inviting clients to the channel does not work (it is yet to be
4413 thought what's the best way to do it).
4415 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4416 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4417 Implemented CUMODE command to change user's mode on the channel.
4418 Supports all modes defined by the protocol specs.
4420 * Added NAMES command reply to return users modes on the channel.
4422 * Removed unnecessary and slow ciphers from lib/silccrypt.
4424 * Set SO_KEEPALIVE option to connection sockets by default.
4426 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4428 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4429 redefined the Notify Payload into protocol specs.
4431 * Added silc_id_payload_parse_id to get ID directly from raw
4434 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4437 accept searching by Client ID as well.
4439 * Added support for LEAVE and SIGNOFF notify types in client library.
4441 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4442 to parse ID Payload from raw data.
4444 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Added flags parameter into silc_ske_assemble_security_properties
4447 function in lib/silcske/silcske.[ch].
4449 * Changed notify client operation to fit better for notify messages
4450 sent by server. The notify payload received from server is now
4451 passed to the application (after parsing it to SilcNotifyPayload).
4452 It is application's responsibility to retrieve the arguments
4453 from the payload and show the message the way it wants. The message
4454 sent by server is implementation specific.
4456 * Changed public keys to comply with the protocol specification.
4457 Old public keys are not supported anymore and are not compatible.
4459 * Removed nickname from Channel Payload as the latest draft removed
4460 it. The client must resolve the nickname from the NAMES command
4461 reply received when it joined the channel.
4463 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4465 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Fixed some errors in protocol specification drafts.
4469 * Created lib/silccore/silcnotify.c to implement Notify Payload
4470 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4471 generic payloads described by protocol specifications. The file
4472 includes implementations for ID Payload and Argument Payload.
4474 * Changed Command Payload implementation to use the new Argument
4475 Payload. Changed command_xxxx_payload to command_payload_xxxx
4476 to comply with SILC coding conventions.
4478 * Added suppport for Argument Payload handling in Notify Payload
4479 implementation as protocol requires it. Added the new support
4480 into server and client lib as well.
4482 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Added support for multiple nicknames on same channel. [n] is
4485 added locally to the nickname if there are more than one same
4486 nicknames on the channel.
4488 * Server now sends all nicknames that matched WHOIS request.
4489 Client also shows the list received from server.
4491 * Added TOPIC command to client side. User can now set and show
4492 current topic on channel.
4494 * Added MOTD command to client and server. Also, server sends the
4495 motd when client connects to the server.
4497 * Changed version strings to comply ISO 8601.
4499 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed protocol error handling in client library. It should now
4502 cope even if the SKE fails for some reason.
4504 * Made new protocol specification drafts for submitting to IETF.
4506 * Implemented TOPIC command to server in silcd/command.c.
4508 * Added two new notify types into lib/silccore/silcnotify.h:
4509 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4510 notify nickname change and topic setting/change on a channel.
4512 * API change of command_reply operation in client library. The
4513 application gets now the status type received from server as well.
4515 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4519 * Cras fixed and optimized the packet handling even further and
4520 it should work now. Minor change to the prototype of function
4521 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4523 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Added new function into lib/silcutil/silcschedule.[ch]:
4526 silc_schedule_with_fd to select() a specified fd. The function
4527 returns after timeout expires or data arrives or goes. The
4528 function is used by packet routines to wait that all data is
4529 received from network.
4531 * Fixed data reading from network in lib/silccore/silcpacket.c.
4532 The code now assures that all data is read from the fd and then
4533 continues packet processing. This was a bug fix since the code
4534 used to drop some data in some circumstances.
4536 * Added new function into lib/silcclient/client.[ch]:
4537 silc_client_start_key_exchange to start key exchange after
4538 connection has been established to server. The code internally
4539 now uses this funtion but its main purpose was to provide it
4540 for applications that perform their own connecting. After
4541 application has created a connection it merely calls this
4542 function to start the key exchange between client and server.
4543 The library takes care of everything else after that.
4545 Updated also lib/silcclient/README to explain the usage of
4548 * Do not send to application information that connection has
4549 been established. Application gets notified it by connect
4552 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Applied cras's patch to add silc_schedule_one function. The
4555 function runs scheduler once and returns.
4557 * Fixed the scheduler after cras messed it up. The timeout
4558 handling works now as it's supposed to work.
4560 * Added into lib/silccore/ silcnotify.h to include notify
4561 message types support. Changed silc_server_send_notify*
4562 functions, in server.[ch], to support those new notify types.
4563 Added the support for the notify types into client library,
4564 as well. Added new notify client operation into ops.h in
4567 * Changed silc_server_packet_send_to_channel to send normal
4568 packets instead of just channel message packets. The function
4569 is now used to send the notify packets to channels. It is not
4570 used to send channel message packets anymore, as server never
4573 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4574 va_arg()s as it seems to require it nowadays. I guess, if SILC
4575 is compiled with older va_arg() the new code should work anyway.
4577 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Splitted core library. Core library (lib/silccore) includes
4580 now only SILC protocol specific core (and common) components.
4581 Created new utility library (lib/silcutil) that includes more
4582 generic purpose stuff. The stuff for util library was taken
4583 from the old core library. This was minor and easy split.
4585 * Created SILC Client Library (lib/silcclient) that includes
4586 implementation of the SILC client without user interface. This
4587 was major move from silc/ directory. The code has been changed
4588 so that it is transparent towards the user interface. The
4589 silc/ directory includes now the same user interface as before
4590 and it uses the new client library. Read lib/silcclient/README.
4591 Basicly, the client library performs everything else related
4592 to SILC except user interface handling. Also, configuration
4593 files are considered to be part of user interface and library
4594 does not handle them.
4596 This change also changed a lot of structures, function naming etc.
4597 Most important change was that SilcClientWindow object was
4598 renamed to SilcClientConnection in the client library. Created
4599 also new file lib/silcclient/ops.h. Also added new files
4600 silc/local_command.[ch] and silc/client_ops.[ch].
4602 All these changes were made to make it easier for user interface
4603 designers to create what ever user interface for the SILC client
4606 It is also expected that the server will be moved to lib
4607 directory as well and SILC Server Library will be created;
4608 sometimes in the future.
4610 * Removed Local commands from lib/silccore/silccommand.h as
4611 they are application specific and new client library does not
4612 handle any of those anymore.
4614 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4615 old client implementation in silc/.
4617 * Added support for callback functions in SILC_LOG_* macros.
4618 Application can now set its own callbacks that will be called
4619 instead of using the default functions that will always print
4620 the debug messages to stderr (or stdout). Also, debugging can
4621 now be disabled by setting silc_debug to FALSE and re-enabled by
4622 setting it to TRUE. Note, that logging will still work even
4623 if debugging is disabled.
4625 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4626 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4627 silc_log_reset_debug_callbacks.
4629 * To enable debugging in silc client one must give now -d
4630 option on command line.
4632 * Changed silc_schedule_init to automatically allocate task queues
4633 if they are not allocated before calling it.
4635 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Added GMP 3.1 into math library.
4639 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4642 a channel in SILC network. The packet is used by servers and
4643 routers to notify other routers that user has left a channel.
4644 This little feature was missing until now. Added the feature
4645 to protocol specification as well.
4647 Added functions: silc_server_send_remove_channel_user and
4648 silc_server_remove_channel_user into server.[ch].
4650 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4651 lib/silccore/silcpacket.h. However, they are not implemented
4654 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Fixed joining to a channel and sending channel messages
4657 between server and router. The channel message sending should
4658 now work inside a cell.
4660 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Fixed the private message sending between server and router.
4663 The private message sending should now work inside a cell.
4665 * Added silc_server_replace_id into server.[ch] to replace
4666 existing ID in the SILC network.
4668 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4669 and silc_idlist_replace_server_id into idlist.[ch] in server.
4671 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Fixed the server to server connections. Server can again now
4674 connect to router. Router to router connections probably does
4677 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Added dynamic protocol registering support. Now protocols can
4680 registered and unregistered on the fly. Patch by cras.
4682 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Added lib/contrib directory to hold routines that some platforms
4685 don't have but are needed by SILC.
4687 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4688 into lin/contrib to provide getopt() and getopt_long() for
4689 those who don't have it.
4691 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added AWAY command to client. When away message is set and
4694 client receives a private message packet the client automatically
4695 replies to the sender with the away message.
4697 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4698 bug seemed to be the cause of recent problems when compiling
4701 * Added version detection support to SKE protocol specification
4702 and added the new changes to the SKE implementation as well.
4703 There were other minor changes in the SKE protocol as well.
4705 Many changes in lib/silcske/silcske.[ch] and in
4706 lib/silcske/payload.[ch].
4708 * Added ^U functionality, clear input line. Patch from cras.
4710 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Mainly small bugfixes on core library. Fixed some debugging
4713 logging and buffer overflow in silclog.c.
4715 * Updated config.sub and config.guess on the distribution tree.
4717 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added command lagging support in server. Client may execute
4720 commands now only once in two seconds.
4722 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Optimized packet reception. MAC computation and checking is now
4725 also more optimized. A lot previously duplicated code is now
4726 used as generic by both client and server.
4728 * Fixed key pair generation in clientutil.c
4730 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Added into lib/silccore/silcbufutil.[ch] new function;
4733 silc_buffer_realloc.
4735 * Moved generic packet sending/encryption functions to
4736 lib/silccore/silcpacket.[ch] from client and server. Some
4737 rewriting of the functions.
4739 * Moved all generic packet reception/decryption functions to
4740 lib/silccore/silcpacket.[ch] from client and server. The
4741 packet processing is now much cleaner in both client and server.
4742 These were major changes in both client and server.
4744 * Created many common functions in server to do packet sending.
4745 Previously code were duplicated a lot, this has been removed
4748 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Rewrote major parts of the ID cache system. Don't know
4751 whether it is better now or not but at least the API is more
4754 * Major rewrite on ID cache stuff on client because of the ID
4755 cache API changes. Added idlist.c to client.
4757 * Also major rewrite on ID cache stuff on server as well.
4758 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4759 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4760 in hand, instead they are all put into the ID cache system now.
4761 All server_idlist_* routines uses ID cache now instead of
4762 traversing its own lists (those lists does not exist anymore).
4763 SilcIDList though still exists. Also, SilcXXXEntry's are
4766 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Finally made the SKE implementation compliant to the protocol
4769 specification. All mp integers are now binary encoded as
4770 opposed being HEX encoded.
4772 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4775 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4776 functions: silc_[encode/decode]_pem. Also added function
4777 silc_encode_pem_file to PEM encode with newlines ('\n') for
4780 * SILC public keys are now encoded either PEM or binary. Same
4781 option is for private keys as well. By default private keys
4782 are binary encoded and public keys PEM encoded. Silly HEX
4783 encoding were removed.
4785 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4786 function to create fingerprints.
4788 * Fixed a bug in SHA1; does not change the original data anymore.
4790 * Partly implemented INFO command on client and server side.
4791 Fixed CLEAR command. Changes to SERVER command; show current
4792 server(s) when giving command without arguments. Added
4793 VERSION command to client.
4795 * Added check to server that unregistered connections cannot
4796 execute commands (unless it is specificly allowed).
4798 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Fixed screen refresh.
4802 * Fixed channel joining bug from client. On some circumstances
4803 client tried to join to a channel it had already joined.
4805 * Added public key verification process into client's protocol.c.
4806 The client now verifies the public key from user and saves
4807 it into ~./silc/serverkeys/ directory.
4809 Added into: clientutil.[ch]: silc_client_verify_server_key.
4811 * Changed SKE protocol's silc_ske_initiator_finish function
4812 to accept callback function that verifies the received public
4813 key. Removed old silc_ske_verify_public_key function.
4815 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4818 silc_pkcs_private_key[_data]_set.
4820 * Made the password and public authentication more cleaner in
4821 server's protocol.c.
4823 * Removed historic and obsolete protocol `channel_auth' from
4824 both client and server.
4826 * Removed wrong way of sending command status messages from
4827 server to client in server's command.c. The old way violated
4828 protocol specification.
4830 Changes to silccore/silccommand.[ch]: removed
4831 silc_command_encode_status_payload -> not needed anymore,
4832 changed silc_command_encode_payload_va to accept extra
4833 argument on variable argument list. The argument type must
4834 now be provided to the function. Also, added new function:
4835 silc_command_encode_reply_payload_va which is same as
4836 normal command_encode_payload_va except command status type
4837 is provided as extra argument.
4839 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Added ~./silc directory handling. The directory includes the
4842 public and private keys for the client.
4844 Added silc_client_check_silc_dir, silc_client_create_identifier
4845 and silc_client_load_keys.
4847 * Implemented SILC protocol compliant public key. Added public
4848 and private key saving to and loading from files.
4850 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4851 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4852 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4853 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4854 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4856 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4857 silc_pkcs_load_[public/private]_key.
4859 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Added silc_server_get_route (route.[ch]) to get connection
4862 data for the fastest route for given ID.
4864 * Implemented INVITE command on client and server. The command
4865 were re-defined in the SILC Protocol Specification and the
4866 implementation now complies with the specification.
4868 * Implemented PING command on client and server.
4870 * Implemented NAMES command on client and server. The server side
4871 supports currently only normal server not router server yet.
4872 Some changes to NAMES definition in SILC protocol specification.
4874 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Implemented LEAVE command on client and server.
4878 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4879 again. This change was made to the protocol as well. Server
4880 should not violate the protocol specification anymore.
4882 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4885 was tested. SOCKS4 was not but should work anyway.
