1 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed a bug in silc_client_command_identify_save when saving
4 new channel information. The channel name was no duplicated
5 and caused crash on exit. Affected file is
6 lib/silcclient/command_reply.c.
8 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Fixed the getkey command handling in the server. Send just
11 empty OK reply to the sender if the key could not be fetched
12 (but everything else was ok, like the key just was not available).
13 Changed the public key parameter to optional in the protocol
14 specs so that empty OK reply can be sent. Affected file
17 Added a message to Irssi SILC client to tell to user if the
18 server did not return a public key.
20 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
22 * Fixed a channel key regeneration bug. It registered new
23 timeout tasks exponentially until all system resources were
24 used. Affected file silcd/server.c.
26 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
28 * Added the SILC Document generator to the scripts/silcdoc.
29 It can be used to generate the Toolkit Reference Manual out
30 of the source tree. Internally it will also use the RoboDoc
31 generator now imported in util/robodoc.
33 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
35 * Added couple of return's in rekey protocol if error orccurred
36 during the protocol. The execution must be terminated.
37 Affected file silcd/protocol.c. Also, terminate the protocol
40 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
42 * The client's Client ID was created initally from the wrong
43 nickname (it could have been in format nick@host) in the
44 silc_server_new_client. Affected file silcd/packet_receive.c
46 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
48 * Added some SILC_LOG_ERROR's to various error conditions
49 if client could not be added to ID cache. Affected files
50 silcd/packet_receive.c and silcd/server.c.
52 * When client's sock->user_data is freed, NULL also the
53 client->router and client->connection pointers. Added check
54 for these pointers being NULL to various places around the
55 code. Affected file silcd/server.c.
57 * Added client->data.registered == TRUE checks to various
58 places around the code to assure that unregistered client's
59 are not handled when it is not allowed. Affected file
62 * Added `bool registered' fields to all
63 silc_idlist_[server|client]_get_* routines to indicate whether
64 the fetched client needs to be registered or not. Affected
65 file silcd/idlist.[ch].
67 * Add your own entry as registered to the ID cache in the
68 server. Affected file server.c.
70 * Fixed a bug in silc_server_new_server. The SilcServer was
71 set as the new server's context instead of SilcServerEntry.
72 This naturally caused some weird bugs.
74 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
76 * Do not delete the channel rekey task when adding it
77 for in silc_server_create_channel_key.
79 * Changed the silc_server_create_channel_key to return
80 TRUE or FALSE to indicate the success of the channel key
83 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Fixed MSVC++ project files and added missing files to
86 Makefiles under win32/.
88 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Do not add TCP_NODELAY flag if the operating system
91 does not have it defined. Affected files are
92 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
94 * Fixed buffer overflow from Irssi SILC Client. Affected
95 file irssi/src/fe-common/core/themes.c.
97 * Fixed double free in client library in the file
98 lib/silcclient/client.c when disconnecting from server.
100 * Applied double free patch from cras to Irssi SILC client.
101 Affected files irssi/src/core/[modules/expandos].c
103 * Fixed the disconnection handling to Irssi SILC Client.
104 The application must call silc_client_close_connection
105 in ops->connect client operation in case of failure of
106 the connection. Affected file is
107 irssi/src/silc/core/client_ops.c.
109 * Do not set sock->protocol to NULL in the function
110 silc_client_close_connection after executing the protocol's
111 final callback since the sock might not be valid anymore.
112 Affected file lib/silcclient/client.c.
114 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
116 * Do not enable SILC_THREADS if the linking with libpthread
117 did not happen. Affected file configure.in.pre.
119 * Added notion to protocol specification that server must
120 verify the sent authentication payload with CMODE when
121 setting the channel founder key. Implemented it to the
122 server. Affected file silcd/command.c.
124 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Added _EXTRA_DIST SILC distribution variable to the
127 distributions file. It is used to conditionally add extra
128 files or directories to the specific distribution. Affected
129 files ./prepare, Makefile.am.pre and distributions.
131 Removed the `_' from the start of the distribution names.
134 * Added README.WIN32 for instructions to compile the Toolkit
137 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
139 * Fixed a double free in disconnection in the server. Affected
140 file is silcd/server.c.
142 * Fixed the lib/silcske/groups.c to work now also with GMP
143 MP library. The string conversion did not work when using
144 specific base and the base is indicated in the string as well.
146 * Created win32/ directory which now includes MSVC++ specific
147 stuff so that toolkit (DLLs) may be compiled with MSVC++.
148 It will appear only in the toolkit distribution
150 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
152 * Changed the key material distribution function in case when
153 the hash output is too short. The data is now concatenated
154 a bit differently than it used to. Made the change to the
155 SKE protocol specification.
157 * Added better GMP detection to configure.in.pre. A patch
160 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
162 * Fixed a minor bug in SKE that might cause some problem on
163 some platforms. Affected file lib/silcske/silcske.c.
165 * Added the cookie checking for initiator in the SKE. It checks
166 that the responder returns the sent cookie unmodified. The
167 affected file is lib/silcske/silcske.c. Added new SKE
168 error type INVALID_COOKIE that can be sent during the
169 negotiation. Fixed some memory leaks as well.
171 * Added the "invalid cookie" error message to Irssi SILC client's
174 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
176 * Added `task_max' field to the SilcClientParams to indicate
177 the maximum tasks the scheduler can handle. If set to zero,
178 default values are used. Affected file lib/silcclient/silcapi.h.
180 * Fixed memory leaks in silc_client_close_connection. Affected
181 file lib/silcclient/client.c.
183 * Added silc_client_del_client_entry to client library to free
184 all memory of given client entry. Affected file is
185 lib/silcclient/idlist.[ch].
187 * Added new functions silc_client_del_channel and
188 silc_client_del_server to delete channel and server entries.
189 Affected file lib/silcclient/[silcapi.h/idlist.c].
191 * Removed silc_client_del_client_by_id from silcapi.h.
193 * Fixed the INFO command to return the server's own info
194 correctly when querying by Server ID. Affected file is
197 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
199 * Removed the non-blocking settings in WIN32 code in the
200 silc_sock_[read/write] and added SleepEx instead. Affected
201 file lib/silcutil/win32/silcwin32sockconn.c. The availability
202 of input data is now checked with FIONREAD and ioctlsocket.
204 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
206 * Call silc_schedule_task_del_by_context in the
207 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
208 Affected file lib/silccore/silcprotocol.c.
210 * Call silc_protocol_cancel for active protocols in the
211 silc_server_close_connection if the funtion
212 silc_server_free_sock_user_data has not been called.
213 Affected file silcd/server.c.
215 * Generic tasks cannot be deleted using the del_by_fd
216 task deleting function since generic tasks does not match
217 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
219 * Added a notion to SILCOPER help file that the SILCOPER works
220 only on router server, not on normal server.
222 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
224 * Added for WIN32 support for the new scheduler as well.
225 Affected file lib/silcutil/win32/silcwin32schedule.c.
227 * Fixed the SHA1 implementation to work on various platforms.
229 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
231 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
232 API. It is part of the scheduler now. Everything else is
233 as previously but some functions has changed their names.
234 Checkout the lib/silcutil/silcschedule.h for the interface.
235 Updated all applications to use the new interface. Affected
236 files are lib/silcutil/silcschedule.[ch].
238 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
240 * Found a bug in the SKE implementation. The HASH value,
241 specified by the protocol, was not computed correctly. The
242 public key of the responder was not added to the computation
243 even though it is mandatory. Affected file lib/silcske/silcske.c.
244 This unfortunately causes incompatibilities with older
247 * Added WIN32 specific network init and uninit functions:
248 silc_net_win32_init and silc_net_win32_uninit to init and uninit
249 the Winsock2. Affected file lib/silcutil/silcnet.h and
250 lib/silcutil/win32/silcwin32net.c.
252 * Set the socket always to nonblocking mode on WIN32 after
253 reading data or writing data. Affected file is
254 lib/silcutil/win32/silcwin32sockconn.c.
256 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
258 * Fixed various compilation problems under WIN32. Affected
259 files lib/silcutil/win32/silcwin32thread.c and
260 lib/silcutil/win32/silcwin32schedule.c.
262 * Removed all _internal.h #includes from public header
263 files. Internal headers must never be included from
266 Removed also the lib/silcske/payload_internal.h file.
268 * All include files that may be needed (public and some others
269 included by the public headers) by application developers are
270 now copied to the ./includes directory. It does not copy any
271 internal headers. Affected file Makefile.defines.pre and all
272 Makefile.am's under lib/ and subdirs.
274 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
276 * Do not change the ~/.silc directory's permissions automatically.
277 Affected file irssi/src/silc/core/clientutil.c.
279 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
281 * Do not cancel the protocol in silc_server_close_connection
282 it might cause recursion. Now cancelled in the function
283 silc_server_free_sock_user_data. Affected file silcd/server.c.
285 * Fixed the silc_server_remove_clients_by_server to regenerate
286 the channel keys correctly finally. Added also new function
287 silc_server_remove_clients_channels to actually do it.
288 Affected file silcd/server.c.
290 * Fixed the silc_server_new_channel to not crash by giving
291 wrong router to the new channel. Affected file is
292 silcd/packet_receive.c.
294 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
296 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
297 which is given as argument to the silc_client_alloc now.
298 It can be used to configure the client and set various parameters
299 that affect the function of the client.
301 * The USERS command in server did not check whether the channel
302 is private or secret. Affected file silcd/command.c.
304 * Added new argument to the USERS command in protocol specification.
305 The USERS command now can take the channel name as argument
306 as well. Added support for this in client and server and
307 updated the protocol specs.
309 * Completed the GETKEY command in client. It can be now used
310 to fetch also servers public key not only some clients.
311 Affected files lib/silcclient/command[_reply].c.
313 * Added silc_client_get_server to return server entry by the
314 server name. Affected files lib/silcclient/silcapi.h and
317 * Redefined the IDENTIFY command in protocol specification to be
318 more generic. It now can be used to query information about
319 any entity in the SILC Network, including clients, servers and
320 channels. The query may be based either the entity's name
321 or the ID. Added support for this in both client and server.
323 Affected files silcd/command.c and lib/silcclient/command.c
326 * Optimized the WHOIS and WHOWAS commands in the server. Removed
327 the _from_client and _from_server functions. Affected file
330 * Added silc_client_get_channel_by_id_resolve to the file
331 lib/silcclient/silcapi.h to resolve channel information by
332 its ID. Added also silc_client_get_channel_by_id that
333 does not resolve it from the server.
335 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Added SilcServerEntry context into the client library
338 to represent one server. The INFO command now allocates
339 these to save the resolved server info. For now on the
340 client library will also keep information about servers,
341 connected and resolved with INFO.
343 The INFO command now allocates the SilcServerEntry context
344 and saves the server info there. The COMMAND_REPLY in
345 the INFO now returns the parameters to application in
346 same order as defined in the protocol specification.
348 The entries are cached in the client->server_cache.
350 * The INFO command is now issued after received the Client ID
351 from the server. Affected file lib/silcclient/client.c.
353 * The CMODE_CHANGE notify may now return also an SilcServerEntry
354 to the application as the mode changer might be server.
355 It is guaranteed that NULL is not returned anymore to the
356 application. Affected file lib/silcclient/client_notify.c.
358 The ID Type is now also passed to the application so that
359 it can check whether the returned entry is SilcClientEntry
362 Added new function silc_client_get_server_by_id to return
363 the server entry by ID. Affected files are the
364 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
366 * Do not create the channel in the Irssi SILC Client when issuing
367 the JOIN command but when received the sucessful JOIN command
368 reply. Otherwise the channel might get created even though we
369 could not join it. The Affected file is
370 irssi/src/silc/core/[silc-channels.c/client_ops.c].
372 * Fixed a channel joining bug in router. The router must also
373 check the channel modes, invite and ban lists etc. when serving
374 the JOIN command sent by normal server. Affected file is
375 silcd/command.c. The router now resolves the client's
376 information from the server who sent the JOIN command if it
377 does not know it, and processes the JOIN command only after
380 * Changed the SilcCommandCb to take new argument; void *context2.
381 Affected file lib/silccore/silccommand.h
383 The second argument in the command callbacks in the server now
384 includes the SilcServerCommandReplyContext if the command was
385 called as pending command callback from the command reply.
386 Otherwise it is NULL. When called as pending the status of the
387 command reply will be checked and if it was erronous the
388 error will be sent to the original sender of the command.
389 This way the client always receives the error messages even
390 though the server was actually the one who received the error
391 when it resent the command to router, for example. Affected
392 files silcd/command[_reply].[ch].
394 * Fixed sending WHOWAS command's error message to client if
395 the requested client could not be found. It was missing.
398 * Changed the CMODE and CUMODE commands reply arguments in the
399 protocol specification. The Channel ID is now sent in both
400 of the commands to identify the channel. Implemented this
401 new feature to the client and server. Affected files
402 lib/silcclient/command_reply.c and silcd/command.c.
404 * Made better checks for invite and ban lists in the JOIN
405 command in server. Affected file silcd/command.c.
407 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
409 * The server now performs the incoming host IP/DNS lookup
410 using the silc_socket_host_lookup and thus does not block
411 the server anymore. Affected file silcd/server.c.
413 * Completed the multi-thread support for SILC Scheduler in
414 the lib/silcutil/silcschedule.c.
416 * Fixed the configure.in.pre to detect the pthread correctly
419 * Fixed a deadlock in silc_task_queue_wakeup in the file
420 lib/silcutil/silctask.c.
422 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
424 * Added new function silc_schedule_wakeup that is used in
425 multi-threaded environment to wakeup the main thread's
426 schduler. It needs to be used when a thread adds a new task
427 or removes a task from task queues. After waking up, the
428 scheduler will detect the task queue changes. If threads
429 support is not compiled in this function has no effect.
430 Implemented the wakeup mechanism to both Unix and WIN32
431 systems. Affected files are lib/silcutil/silcschedule.[ch],
432 lib/silcutil/unix/silcunixschedule.c and the
433 lib/silcutil/win32/silcwin32schedule.c.
435 * Added new function silc_task_queue_wakeup to wakeup the
436 scheduler by the specified task queue. Affected file
437 lib/silcutil/silctask.[ch].
439 * The silc_socket_host_lookup_start now wakes up the scheduler
440 after adding the timeout task. Affected file is
441 lib/silcutil/silcsockconn.c.
443 * The silc_socket_host_lookup is synchronous now if the threads
444 support is not compiled in. However, the callback is still
445 called asyncronously through the scheduler, anyway. Affected
446 file lib/silcutil/silcsockconn.c.
448 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
450 * Added new function silc_socket_host_lookup to perform
451 asynchronous IP and FQDN lookups for the socket connection.
452 Affected files lib/silcutil/silcsockconn.[ch].
454 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
456 * Added SILC_MUTEX_DEFINE to define the mutex on environments
457 that may or may not compile the mutex support in.
459 Changed the silc_mutex_alloc interface. It allocates the
460 mutex now to the sent pointer and returns TRUE or FALSE.
462 Affected file lib/silcutil/silcmutex.h.
464 * Wrote the SILC Task Queue interface to support multi-threads.
465 Affected file lib/silcutil/silctask.[ch].
467 * Wrote the SILC Scheduler to support multi-threads. Affected
468 file lib/silcutil/silcschedule.c.
470 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Implemented the SILC Mutex API and SILC Thread API for WIN32
473 in lib/silcutil/win32/.
475 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
477 * Defined SILC Mutex API and SILC Thread API and implemented
478 them for Unix. Affected files are
479 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
480 lib/silcutil/unix/silcunixmutex.c and
481 lib/silcutil/unix/silcunixthread.c.
483 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
485 * Fixed the silc_server_remove_clients_by_server's channel
486 key re-generation. The hash table handling was incorrect
487 and would not work with many channels. Affected file is
490 * Fixed some memory leaks around the server code.
492 * Rewrote the silc_server_get_users_on_channel to support IPv6
493 based Client ID's. Affected file silcd/server.c.
495 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
496 specification. However, a separate document must be written
497 to define the detailed signing procedure and the payload
498 associated with the flag. Defined the flag to the
499 lib/silccore/silcchannel.h as well.
501 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
503 * Changed the dynamic tables to static size tables in the
504 lib/silccrypt/silchmac.c.
506 * Removed GCC dependencies from the code. A patch by cras.
508 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Do not show the error "Error receiving packet bla bla"
511 in server if it really was not an error (-2 means that reading
512 is pending). Affected file silcd/server.c.
514 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
516 * Fixed a possible crash in silc_server_remove_clients_by_server
517 in silcd/server.c. Fixed there also some memory leaks.
519 * Fixed the silc_idlist_replace_client_id. It could replace
520 wrong key in the hash table. Affected file silcd/idlist.c.
522 * Do not check whether there are global users on the channel
523 if the channel->global_users is FALSE. Affected functions
524 silc_server_remove_from_one_channel and
525 silc_server_remove_from_channels in silcd/server.c. Also,
526 do not check if the removed client is local as we can be
527 sure that global client was not removed from the channel
528 and checking for global users is not needed.
530 * The silc_server_remove_clients_by_server now re-generates
531 the channel keys correctly for those channels that had
532 clients removed from them. Affected file silcd/server.c.
534 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Found the reason of random crashes in the server. We weren't
537 ignoring the SIGPIPE signal (which can be sent in write())
538 and it crashed the server. Affected file silcd/silcd.c.
540 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Assure that sock->user_data is not NULL in the function
543 silc_server_packet_send in silcd/packet_send.c.
545 * Disconnect the remote connection if it could not be added
546 to any ID lists in the server. The affected file is
549 * Check in silc_server_packet_send[_real/dest] that the
550 socket is not disconnecting and ignore the data if it is.
551 Affected file silcd/packet_send.c.
553 * Define inline to __inline on native WIN32 compilation.
554 Affected file includes/silcwin32.h.
556 * Added some explicit type casts for inline code since MSVC
557 require them. Affected files lib/silcutil/silcbuffer.h,
558 lib/trq/silcdlist.h and lib/trq/silclist.h.
560 * Print warning in log files from now on if the packet
561 decryption fails. Affected file silcd/server.c.
563 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Changed the `say' client operation's interface to accept
566 new `type' argument to indicate the type of the message sent
567 by the library. The application may filter the library's
568 messages according the type. The affected file is the
569 lib/silcclient/silcapi.h.
571 * Added two new functions to lib/silcclient/silcapi.h:
572 silc_client_del_client and silc_client_del_client_by_id.
573 Affected file lib/silcclient/idlist.c.
575 * Moved the clientincludes.h from includes/ to silc/ and
576 serverincludes.h from includes/ to silcd/.
578 * The modes for the CMODE and CUMODE are now passed as
579 uint32 for application with COMMAND_REPLY. The affected
580 file is lib/silcclient/command_reply.c.
582 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
584 * /WHOIS without arguments shows client's own information.
585 Affected file lib/silcclient/command.c.
587 * Changed PING to not accept any arguments. The specs
588 says that client can ping only the connected server so
589 requiring an argument is not needed. Affected file is
590 lib/silcclient/command.c.
592 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
594 * Fixed a fatal bug in private message sending and reception
595 encryption and decryption when using private message keys.
596 The implementation was incorrect and did not follow the
597 specification. It causd that some of the message were
598 lost since it did not use the sending and receiving keys
599 as the protocol suggests. This has been fixed and will cause
600 incompatibilities with older clients when sending private
601 message encrypted with private message keys. Affected files
602 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
603 and various other in Irssi SILC Client.
605 Added `responder' boolean argument to the functions
606 silc_client_add_private_message_key[_ske] to indicate when
607 the key is added as responder or initiator of the key
610 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
612 * Removed the silc_ske_check_version function and created
613 a SilcSKECheckVersion callback. Added also a function
614 silc_ske_set_callbacks that is now used to set all SKE
615 callbacks. The callback functions are not given to
616 the SKE functions anymore, but this function is used to
619 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
621 * Added `silc_version' argument to the silc_client_alloc
622 to define the version of the application for the library.
623 The library will use the version string to compare it
624 against the remote host's (usually a server) version
625 string. Affected file lib/silcclient/silcapi.h
627 * Added the KE protocol context to Key Agreement context
628 in client library so that we can abort the SKE if it
629 is in process when we get timeout. Affected file is
630 lib/silcclient/client_keyagr.c.
632 * Do not resolve the client ID forever if it returns in the
633 first time that such client does not exist. This was done
634 for example with private message. Affected file is
635 lib/silcclient/client_prvmsg.c.
637 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
639 * Do not add regex.h for WIN32. The affected file
640 includes/silcincludes.h.
642 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
643 not work yet 100%. It generates the DLL's automatically
644 when compiling with --with-win32 under cygwin.
646 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
648 * lib/contrib/regex.c is not compiled on WIN32.
650 * Added silc_net_get_socket_opt function to the
651 lib/silcutil/silcnet.h.
653 * Added includes/silcwin32.h for WIN32 specific includes
656 * Do not use ptime structure or any of the posix process
657 functions on WIN32 in lib/silccrypt/silrng.c.
659 * Added silc_gettimeofday to provide generic function
660 for struct timeval on all platforms. Added the function
661 to lib/silcutil/silcutil.h.
663 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Moved the lib/silccore/silcsockconn.[ch] to the utility
666 library as they clearly belong there. As a plus side we
667 can make the actual socket connection routines platform
670 Added also new generic function silc_socket_read and
671 silc_socket_write (that used to be silc_packet_[read/write].
672 The implementation of these are platform specific.
674 * Added WIN32 specific routines of silc_socket_[read/write]
675 to lib/silcutil/win32/silcwin32sockconn.c.
677 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Added preliminary support for native WIN32 compilation under
680 cygwin (using the -mno-cygwin option for GCC) to the
681 ./configure.in.pre. The --with-win32 now prepares the
682 compilation for native WIN32.
684 * Rewrote the SILC Scheduler interface in the file
685 lib/silcutil/silcschedule.h. The scheduler is now context
686 based and does not have anymore any global static scheduler.
687 Moved the Unix scheduler to the lib/silcutil/unix/ directory
688 and created lib/silcutil/win32 directory for WIN32 based
691 * Added Unix specific network routines to the
692 lib/silcutil/unix/silcunixnet.c and the old
693 lib/silcutil/silcnet.c includes now only generic routines.
695 Added WIN32 specific network routines to the
696 lib/silcutil/win32/silcwin32net.c.
698 * Added Unix specific utility functions from the
699 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
701 * Added WIN32 SILC Scheduler to the file
702 lib/silcutil/win32/silcwin32schedule.c. The code is of course
705 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Do not handle JOIN notify in the server if the target client
708 is not registered (idata->registered == FALSE). The affected
709 file is silcd/packet_receive.c.
711 * Update the nickrec->founder in event_cumode in the Irssi SILC
712 client. Affected file irssi/src/silc/core/silc-channels.c.
714 * Fixed the CUMODE_CHANGE notify handling in the server when
715 server and router are announcing their clients on channels.
716 Now the mode changes are saved and notified correctly. The
717 affected file is /silcd/packet_receive.c.
719 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
720 They really did not replace the cache entry in the ID Cache.
721 Now they do that. Affected file silcd/idlist.c.
723 * Fixed the KICK notify handling in the Irssi SILC client to
724 update the channel records so that the kicked client does not
725 appear to be on the channel. The affected file is
726 irssi/src/silc/core/silc-channels.c.
728 * Always update the conn->current_channel when executing command
729 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
731 * Fixed the KILL notify handling in Irssi SILC client to remove
732 the killed client on all channels.
734 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Fixed the silc_parse_command_line to remove extra spaces
737 from the start and end of the arguments. Affected file is
738 lib/silcutil/silcutil.c.
740 * Cancel and free any active protocol in the function
741 silc_server_close_connection. Affected file silcd/server.c.
743 * Cancel and free any active protocol in the function
744 silc_client_close_connction. Affected file is
745 lib/silcclient/client.c.
747 * Do not execute the KILL command for clients that are in
748 history (ie. they are not in the network). Affected file is
751 * Fixed KILL notify handling, client does not crash anymore.
752 Affected file irssi/src/silc/core/silc-channels.c.
754 * Reduced the default packet buffer size from 2048 to 1024 in
755 lib/silccore/silcpacket.c.
757 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
758 counter to the SKE context that is incresed when the SKE library
759 performs async operation outside the library. If the outside
760 process frees the SKE context and FREED status will be set
761 and the library will detect after the sync operation that the
762 libary is freed. The affected files are
763 lib/silcske/silcske[_status].[ch].
765 * Resolve the client entry information in the function
766 silc_client_channel_message to assure that NULL pointer is not
767 passed as client entry to the application. */
769 * Fixed the task timeout calculation to assure that there is
770 never negative timeouts. The affected file is
771 lib/silcutil/silcschedule.c.
773 * Fixed the channel user mode notification sending in server.
774 It was sent point-to-point to the router (or to server by router)
775 but it needs to be destined to a channel. The routines now
776 supports sending the channel user mode notifys to the channels
777 when announcing clients and channels. Affected files are
778 silcd/server.c and silcd/packet_receive.c.
780 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
781 It did not actually replace the old channel entry in the cache.
782 Affected file lib/silcclient/client_notify.c.
784 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
786 * Fixed a possible crash in silc_packet_send_prepare. It now
787 assures always that there is enough space in the buffer and
788 at the tail area of the buffer (for MAC).
790 Fixed the inbound buffer reallocation in silc_packet_read.
791 It was old code and did not handle the reallocation correctly.
794 The affected file is lib/silccore/silcpacket.c.
796 * Fixed buffer overflow in silc_parse_nickname in the file
797 lib/silcutil/silcutil.c.
799 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * make install generates new server keys only if there is not
804 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
807 Added check that if the NOREPLY is set then we will not send
808 the away message. This avoids infinite loop of away messages
809 if both clients are away. The affected file is
810 lib/silcclient/client_prvmsg.c.
812 * Fixed client crash if /NICK was given without arguments.
813 Affected file lib/silcclient/command.c.
815 * Server does not send the invite list in INVITE command back
816 to the client if the list was not altered. Added this notion
817 to the protocol spec as well. Affected file silcd/command.c.
819 Fixed possible crash in INVITE command by checking the
820 value of silc_server_get_client_route command.
822 * Fixed the INVITE notify type handling. The arguments are now
823 taken in correct order and client does not crash. The affected
824 file is irssi/src/silc/core/silc-channels.c.
826 Removed the "Inviting xxx to channel" message from the
827 client library away and let the application handle it.
828 Affected file lib/silcclient/command.c. Added that message
829 to Irssi SILC client's message formats.
831 * Fixed CMODE command crash in client. It now checks the
832 amount of arguments correctly and does not crash. The affected
833 file is lib/silcclient/command.c.
835 * Do not create new channel automatically in silc_channels_join
836 but check whether the channel by that name already exists.
837 Affected file irssi/silc/core/silc-channels.c.
839 * Do not send the SERVER_SIGNOFF to router if the disconnected
840 entity was the router. Affected file silcd/server.c.
842 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
843 SILC client as it was missing from there.
845 Added the handling of the KICK notify to the Irssi SILC client
846 as it was missing. Added "you have been kicked" message to
847 Irssi SILC client's message modules formats.
849 Added the handing of the KILL notify to the Irssi SILC client
850 as it was missing. Added the kill message module formats
853 The affected file is irssi/src/silc/core/silc-channels.c.
855 * The router did not save the channel mode the server announced.
856 Affected file silcd/packet_receive.c.
858 * Fixed a possible crash in INFO command in server. If the
859 server did not provide the server info it crashed. Affected
860 file silcd/command.c.
862 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Fixed the GETKEY command in the server to check also the
865 global list. Otherwise the GETKEY would not work correctly
866 in normal SILC server. Affected file silcd/command.c.
868 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Fixed GETKEY crash, it crashed if the command did not succseed.
872 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
875 is now real and not just an macro interface to GMP.
877 Removed the entire GMP from the source tree and imported new
878 NSS MPI library instead. Reason for removing GMP is that it is
879 extremely large and compiles extremely slow. The NSS MPI
880 is only a few files and compiles in less than 10 seconds.
881 The speed is also about the same as GMP. The MPI is imported
884 If the system has GMP installed we will still use the GMP.
885 If it is not then the NSS MPI will be compiled.
887 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Merged a long nickname (127 characters long) crash bugfix from
890 Irssi CVS tree. Affected file irssi/src/core/misc.c.
892 * Merged a freed memory reference bugfix from Irssi CVS tree.
893 Affected file irssi/src/core/commands.c.
895 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Added the server's public key sving and verification to the
898 server when performing the SKE. This was missing and the
899 remote server's (or router's) public key was accepted without
900 checking whether we have it previously or trust it at all.
901 Affected file silcd/protocol.c.
903 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Check in the silc_server_timeout_remote if protocol is active
906 and make sure that the protocol's final callback is called so
907 that all memory if freed. Affected file silcd/server.c.
909 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * silc_server_whois_send_reply crashed the server if the nickname
912 was 127 characters long. Affected file silcd/command.c.
914 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added sanity check to the silc_server_new_client. If the hostname
917 is provided inside username then check that the provided hostname
918 really is the same as the resolved one. If the hostname was not
919 resolved then check it from the public key. Affected file is
920 silcd/packet_receive.c.
922 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
923 if the server disconnected us and the connection is not valid
924 anymore. Affected file irssi/src/silc/core/silc-channels.c.
926 * Moved the silc_client_[chmode|chumode|chumode_char] away from
927 the library to the lib/silcutil/silcutil.[ch].
929 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Close log file after open. Affected file
932 lib/silcutil/silclog.c.
934 * Check whether sock == NULL in silc_client_send_packet and return
935 if it is. Affected file lib/silcclient/silcclient.c.
937 * Check rec->entry == NULL in the Irssi SILC Client before
938 sending the channel message. Affecte file is
939 irssi/src/silc/core/silc-servers.c.
941 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Merged a splitted window bugfix from Irssi CVS tree. The
944 affected file is irssi/src/fe-text/textbuffer-view.c.
946 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
947 It did not print nickname.
949 * Improved the distributions system a bit.
951 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
954 irssi/src/fe-text/gui-window.c.
956 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
957 to in-active server. The affected file is
958 irssi/src/silc/core/client_ops.c.
960 * Resolve the client in USERS command reply if the entry does
961 not have username resolved. The affected file is
962 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
963 command to WHOIS command to really resolve stuff. The USERS
964 is not used any more in any critical section so WHOIS can
965 be used even though it might be slower than IDENTIFY.
967 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
970 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Changed the protocol API a bit more consistent in the
973 lib/silccore/silcprotocol.[ch].
975 * Changed the following headers to ROBODoc format:
977 lib/silccore/silcpayload.h
978 lib/silccore/silcprotocol.h
979 lib/silccore/silcsockconn.h
981 All core library headers are now formatted.
983 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Fixed a bug in Irssi SILC client; do not show that you are
986 server/router operator if you really are not. Affected file is
987 irssi/src/silc/core/client_ops.c.
989 * Renamed silc_command_free_payload to silc_command_payload_free.
990 Affected file lib/silccore/silccommand.h
992 * Added silcmath.h to include the prototoypes of various routines
993 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
996 * Changed the following headers to ROBODoc format:
998 lib/silccore/silcchannel.h
999 lib/silccore/silccommand.h
1000 lib/silccore/silcid.h
1001 lib/silccore/silcidcache.h
1002 lib/silccore/silcmode.h
1003 lib/silccore/silcnotify.h
1004 lib/silccore/silcpacket.h
1005 lib/silcmath/silcmath.h
1007 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Added checking to the server code not to start the server if
1010 ciphers and stuff are not configured properly. Affected files
1011 silcd/serverconfig.[h] and silcd/server.c.
1013 * Changed the layout of the header files of the public interfaces
1014 in the SILC libraries. The new layout supports ROBODoc
1015 documentation tool (and some others) so that it is easy to create
1016 a library reference manual. All the other headers and source
1017 code must still follow the CodingStyle document. Also source
1018 code must not include these ROBODoc stuffs, only the headers.
1019 Furthermore, all public interface headers must now be named
1020 by using `silc' prefix, example: silcapi.h, silccipher.h.
1021 Some files were renamed due to this. All the other headers
1022 must not be used as public interfaces. I will update the
1023 CodingStyle document later. Changed following headers, so far:
1025 lib/silcclient/silcapi.h
1026 lib/silccore/silcauth.h
1027 lib/silccore/silcprivate.h
1028 lib/silccrypt/silcdh.h
1030 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Removed silc_client_packet_send_flush from the client library
1035 as it is not needed. Affected file lib/silcclient/client.[ch].
1037 * Added printing of message of unresolved authentication method
1038 to the Irssi SILC client. Added it to the module formats.
1039 Removed the same message from the client library.
1041 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1043 * Added new distribution feature, DISTLABEL. Every distribution
1044 can define own preprocessor label that can be used in the
1045 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1046 file distributions, acconfig.h.pre and prepare.
1048 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Added Makefile.defines_int to include the actual definitions
1051 for Makefile.defines.in. Tested the new distribution system,
1052 created distributions and tested installation.
1054 * Added AWAY message printing to the Irssi SILC client. Added
1055 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1057 * Added SCONNECT command to call the SILC's CONNECT command.
1058 Cannot use CONNECT directly since Irssi uses that internally.
1059 Affected file irssi/src/silc/core/silc-servers.c.
1061 Added ACTION local command. It is same as ME command but takes
1062 the channel as mandatory argument.
1064 Rewrote some of the Irssi's help files to suite for SILC
1067 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added Makefile.defines[.in] that should for now on be included
1070 in all Makefile.am file in the source tree. That file includes
1071 all common compilation definitions for SILC source tree.
1073 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Minor changes to the ./prepare script to change the package
1076 name according the distribution name to the configure.in.
1078 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Created new distribution system. Added file `distributions'
1081 that defines all the distributions that can be created out of
1082 the SILC source tree. The ./prepare script now reads that
1083 file to determine how to prepare the distributions. The
1084 first argument to the ./prepare is the name of the distribution
1085 and second is the version of the distribution. If given
1086 without arguments it creates the default (toolkit) distribution
1087 with the default version (defined in ./prepare).
1089 All Makefile.am files that are subject to the distributions
1090 are now named as Makefile.am.pre. These are ./Makefile.am
1091 and lib/Makefile.am. Others may be changed later.
1093 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added invite list, ban list, some key management and connection
1096 error message printing to module formats in the Irssi SILC client.
1098 * Added new silc_client_set_away_message to set the away message
1099 that is back to the person who sent private message. The
1100 affected file lib/silcclient/silcapi.h and the
1101 lib/silcclient/client_prvmsg.c.
1103 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Fixed the private message sending in the Irssi SILC client,
1106 added local command KEY to the Irssi SILC client.
1108 Added key management and key agreement message formats to the
1109 irssi/src/fe-common/silc/module-formats.[ch].
1111 Added USERS (alias WHO) printing, server/router operator
1112 indication and LIST command printing to the module formats.
1114 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1116 * Fixed channel joining notify handling, cumode notify handling
1117 from Irssi SILC client.
1119 * Added SILC specific module-formats to the Irssi SILC client so
1120 that SILC specific message hilighting, colors etc is possible.
1121 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1123 Added channel mode, channel user mode, actions, notices,
1124 whois and whowas printing to the the module-formats.c.
1126 * Fixed a bug in channel deletion in the server. The channel
1127 is not left to the cache even if the channel founder auth mode
1128 is set when there are no users anymore on the channel. Affected
1129 file silcd/server.c.
1131 * The silc_net_localhost now resolves the entire hostname including
1132 the domain name. Affected file lib/silcutil/silcnet.c.
1134 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1136 * Changed the ask_passphrase client operation to be ascynchronous.
1137 It has now a completion callback and a context that the
1138 application must call after it has got the passphrase from
1139 the user. Affected files lib/silcclient/silcapi.h,
1140 lib/silcclient/protocol.c, lib/silcclient/command.c and
1143 Added SilcAskPassphrase callback that the application calls
1144 to deliver the passphrase to the library.
1146 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1147 The public key verification and especially a certificate
1148 verification is asynchronous procedure.
1150 Added new SILC_SKE_STATUS_PENDING status to indicate the
1151 request is pending and a callback will be called to finalize
1154 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1155 indicate that remote end did not send its public key (or
1156 certificate), even though we require it. Added check for this
1157 condition in the SKE. This was a security bug, now fixed.
1159 Defined new SilcSKEVerifyCbCompletion callback that is called
1160 when the verification process is completed.
1162 The affected files lib/silcske/silcske_status.h and
1163 lib/silcske/silcske.[ch].
1165 * Changed the verify_public_key client operation to be async
1166 as well. Defined SilcVerifyPublicKey callback that is used to
1167 indicate the success of the public key verification process.
1169 Changed the server and client to use the new async client
1172 * Changed the Irssi SILC client's internal scheduler to be called
1173 twice as many times as it used to be. As a result the client
1174 should be a bit faster now. Affected file is
1175 irssi/src/silc/core/silc-core.c.
1177 * Added support to Irssi SILC client of asynchronous public key
1178 verification and passphrase inquiry. Affected file is
1179 irssi/src/silc/core/silc-core.c.
1181 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Do not say "You have left channel %s" in client library.
1184 Moved it to the application. Affected files are
1185 lib/silcclient/command.c and silc/client_ops.c.
1187 * Fixed silc_client_get_clients. Command context was not
1188 duplicated and was freed memory in the callback. Affected
1189 file lib/silcclient/idlist.c.
1191 * Do not say "you are now talking..." on JOIN command in the
1192 client library. The appliation must handle it.
1194 * Do not say ".. changed topic to" in command reply in the
1195 client libary. The application must handle it.
1197 * Fixed TOPIC command sending in the client library.
1199 * Fixed a memory leak in silc_client_command_free in the file
1200 lib/silcclient/command.c.
1202 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Imported a modified version of Irssi client to the source tree.
1205 The Irssi will be used to create a new client called
1206 Irssi SILC. Imported to irssi/.
1208 Added silc_core_init_finish function to the Irssi. Affected
1209 file irssi/configure.in.
1211 A lot changes in the Makefile.ams around the irssi tree.
1213 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Do not rehash if the new size is same as the old size of the
1216 hash table, in the silc_hash_table_rehash*. The affected file
1217 lib/silcutil/silchashtable.c.
1219 * Replaced hash_table_del_by_context calls from the server
1220 (when channel->user_list and client->channels) to the
1221 hash_table_del as it is sufficient and faster.
1223 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Added silc_hash_table_list, silc_hash_table_get and the
1226 SilcHashTableList structure to provide an alternative way to
1227 traverse the hash table. The affected files are
1228 lib/silcutil/silchashtable.[ch].
1230 * Changed the server's idlist routines to use the hash table
1231 routines to optimize the code.
1233 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Replaced the client entry's `channel' list and channel entry's
1236 `user_list' list to hash tables for optimized lookup. Changed
1237 the code to use the hash table interface around the code.
1238 Affected file lib/silcd/idlist.[ch].
1240 * Added `auto_rehash' boolean argument to the function
1241 silc_hash_table_alloc to indicate whether the hash table should
1242 auto-rehash when it thinks is appropriate time. It will
1243 increase the hash table size if the there is twice as much
1244 entries in the table than the size of the table, and will
1245 decrease the size if there are twice as less entries than
1246 the size of the table.
1248 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1252 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * silc_idcache_purge_by_context deletes the entry now by context
1255 as it is supposed to do. Affected file lib/silccore/idcache.c.
1257 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1258 client is not anymore valid (WHOWAS givens the info) and not
1259 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1261 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1263 * Removed the `data' and `data_len' arguments from the ID Cache
1264 interfaces and added `name' argument. ID Cache does not handle
1265 anymore the binary data only a names associated with given ID.
1267 * When hashing a Client ID with silc_hash_id the entire ID is
1268 not hashed anymore, instead only the hash of the Client ID is
1269 hashed. This way we can access the Client ID from the cache
1270 with Client ID but with the hash of the ID (which is a hash of
1271 the nickname) as well without any difference in performance.
1273 Added also silc_idcache_find_by_id_one_ext to do one on one
1274 searching when we have the actual ID. Added also function
1275 silc_hash_client_id_compare. The affected files are
1276 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1278 * When hashing the name associated with a ID it is always done
1279 in lowercase. This way we can access the cache without worrying
1280 about case-sensitivity, even though, for example nicknames are
1283 * Fixed a bug in server with channel message sending. It put
1284 wrong ID type as destination ID. The affected file
1285 silcd/packet_send.c.
1287 * silc_idcache_del_by_context now deletes from all hash tables
1288 by context. Affected file lib/silccore/idcache.c.
1290 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Changed the client library to use the new ID Cache interface.
1293 Changes around the source tree.
1295 * Added silc_hash_table_rehash_ext to rehash with specific
1296 hash function. Affected file lib/silcutil/silchashtable.[ch].
1298 * Added silc_hash_string_compare to compare two strings in the
1299 hash table. Affected file lib/silcutil/silcutil.[ch].
1301 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1303 * Added new function silc_idcache_del_by_context into the
1304 lib/silccore/idcache.[ch].
1306 * Changed the server's ID list routines to use the new ID Cache
1307 interface. Changes around the source tree.
1309 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added silc_hash_table_del[_by_context]_ext functions in to the
1312 lib/silcutil/silchashtable.[ch].
1314 Removed silc_hash_table_find_all* routines and added new
1315 silc_hash_table_find_foreach to replace them.
1317 Added silc_hash_table_replace_ext function as extended
1318 replacing function. Separated the simple hash table interface
1319 from the extended hash table interface in the file
1320 lib/silcutil/silchashtable.h.
1322 * Fixed minor bugs and changed it to use some of the new
1323 hash table functions in lib/silccore/idcache.c
1325 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Added new function silc_hash_table_find_all to return all keys
1328 in the hash table by the specified key. As the hash table is
1329 collision resistant it also makes it possible to have several
1330 duplicate keys in the hash table. This function may be used to
1331 find all of the keys from the hash.
1333 Added user_context arguments to the SilcHashFunction,
1334 SilcHashCompare and SilcHashDestructor to deliver user specified
1337 Added new fuctions silc_hash_table_find[_all]_ext to do
1338 extended lookup with specified hash and compare functions and
1339 specified user contexts.
1341 Added new function silc_hash_table_add_ext to add the key
1342 with specified hash function and user context.
1344 Added new function silc_hash_table_foreach to traverse all
1345 entrys in the hash table. Added SilcHashForeach callback
1348 Added new function silc_hash_table_del_by_context to delete
1349 the entry only if the context associated with the key matches.
1351 Affected files are lib/silcutil/silchashtable.[ch].
1353 * Removed silc_hash_[server/client/channel]_id and added just
1354 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1355 silc_hash_id_compare to compare two ID's using as the hash table
1356 comparison function. Added also silc_hash_data to hash
1357 binary data and silc_hash_data_compare to compare it.
1359 * Removed silc_idlist_find_client_by_hash as it is not needed
1360 anymore. Affected file silcd/idlist.[ch].
1362 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1363 to use internally the SilcHashTable. The new ID Cache is a lot
1364 faster than the old one. Some of the ID Cache interface was also
1365 rewritten and obsolete and stupid functions were removed.
1367 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1369 * Added entry_count field to the SilcHashTable to keep the number
1370 of the entries in the table. Implemented the function
1371 silc_hash_table_rehash. Added new function
1372 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1374 Fixed a minor bug in silc_hash_table_free.
1376 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1377 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1378 into the lib/silcutil/silcutil.[ch].
1380 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1382 * Implemented a collision resistant hash table into the
1383 lib/silcutil/silchashtable[ch]. See the header and the source
1384 for the SilcHashTable API.
1386 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Merged dotconf version 1.0.2 into lib/dotconf.
1390 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Do not compile anything in lib/silcsim/* if the SIM support
1393 is not enabled. The tree should now compile without problems
1396 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * Compiled the SILC under cygwin. Compiled and tested briefly
1399 without problems. More tests needed. The SIMs didn't compile
1402 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1404 * Fixed possible crash in silc_get_username in the
1405 lib/silcutil/silcutil.c.
1407 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Fixed a va_arg in silc/client_ops.c.
1411 * Oops, RC5 routines were named AES and caused some problems
1412 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1414 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Added new SilcIDIP structure into the lib/silccore/id.h and
1417 replaced the old `ip' fields from all SILC ID's to that type.
1418 This is a step towards IPv6 support.
1420 The silc_id_get_len takes now the ID as an extra argument.
1421 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1422 both IPv4 and IPv6 based ID's.
1424 The affected files are lib/silccore/id.[ch] and other files
1425 around the tree using these routines.
1427 * Removed the ID length arguments in server from various
1428 silc_server_send_notify_* routines -> they are not needed
1431 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Fixed memory leak in silc_encode_pem_file in the file
1434 lib/silcutil/silcutil.c.
1436 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Check minor version as well in the SKE. Affected files are
1439 silcd/protocol.c and lib/silcclient/protocol.c.
1441 * Added --identifier option to the server so that an identifier
1442 can be when creating the public key for the server. Affected
1443 file is silcd/silcd.c.
1445 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1446 lib/silccrypt/silcpkcs.c.
1448 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Register default ciphers and stuff when using -C option with
1451 the server. Affected file sildc/silcd.c.
1453 * Put back the servers public key filename format, it is better
1454 than the new one. For now, the client keys are saved with the
1455 new filename format. The affected file silc/client_ops.c.
1457 * Implemented the Cipher API for the rest of the ciphers that
1458 did not implement it or implemented it the wrong way.
1460 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1462 * Register default ciphers and stuff when using the -S option
1463 in the client. Affected file silc/silc.c. Same also when
1464 creating new key pair with -C option.
1466 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Fixed the silc_verify_public_key client operation function to
1469 save the public keys differently. The fingerprint is now
1470 used as filename and not the hostname. This way also the
1471 client keys are saved uniquely and not with hostnames. The
1472 affected file is silc/client_ops.c.
1474 * Trimmed the silc_hash_fingerprint function to remove extra
1475 whitespaces from the end of the fingerprint. The affected
1476 file is lib/silccrypt/silchash.c.
1480 * Added silc_cipher_register_default function to register all
1481 default ciphers. It can be used when configuration files
1482 does not exist and the application does not want any specific
1483 ciphers in any specific order.
1485 The SilcDList is now used as silc_cipher_list dynamically
1486 allocated cipher list. Removed the static list all together
1487 and now all ciphers must be allocated to the dynamic list.
1488 The silc_cipher_alloc routine was changed to check only the
1491 All silc_cipher_* routines that used to return int returns
1494 The affected files lib/silccrypt/silccrypt.[ch].
1496 * The same thing was done to silc_hash_* as for silc_cipher_*
1497 routines. Affected files lib/silccrypt/silchash.[ch].
1499 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1500 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1501 Added also silc_pkcs_[un]register[_default] functions.
1502 Removed the data_context from the PKCS API.
1504 * Added silc_hmac_register_default function to register default
1505 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1506 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1507 to unregister all hmacs at once.
1509 * Register the default ciphers, hash functions, PKCSs and HMACs
1510 if client's configuration file does not exist. The affected
1513 * The client did not load the hash functions from the SIM
1514 modules at all. Added support for this. Affected file is
1515 silc/clientconfig.c.
1517 * When decoding public key with silc_pkcs_public_key_decode, check
1518 the supported algorithm only if PKCS are registered. Affected
1519 file lib/silccrypt/silcpkcs.c. The same was done with the
1520 silc_pkcs_private_key_decode.
1522 * Fixed the SILC List routines to keep the list always in order.
1523 It used to change the list's order when traversing the list but
1524 not it preserves the order. Affected file lib/trq/silclist.h.
1526 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Added the client library to use the SilcSocketConnection's
1529 reference counter (by silc_socket_dup) to prevent the bug that
1530 the socket object may be freed underneath async operation.
1532 * The name resolv library checking fixes in the configure.in.pre.
1535 * Created new version of the protocol drafts for future
1536 development. The -03 drafts are the ones that will be changed
1537 in the trunk now and the -02 will remain as they are.
1539 * Send list of CUMODE notifys to the router when announcing
1540 the channel users to the router. Affected file silcd/server.c.
1541 If the router receiving channel founder CUMODE for a channel
1542 that already has channel founder it will send CUMODE notify
1543 to the sender to remove the channel founder rights from the
1544 announced client. Affected file silcd/packet_receive.c.
1546 * The CUMODE notify may now use Server ID as well as the entity
1547 who changes the mode. Updated protocool specs.
1549 * Updated INSTALL and README files.
1551 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * New web pages in the http://silc.pspt.fi. The pages was
1558 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Implemented the [DenyConnectin] config section in the server.
1561 Added silc_server_config_denied_conn to check whether incoming
1562 connection is denied. Affected file silcd/serverconfig.[ch].
1564 * Do not check the ports when checking the incoming configuration
1565 data if the port is 0, meaning any. Affected file is
1566 silcd/serverconfig.c.
1568 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Fixed buffer overflow in silc_string_compare in the file
1571 lib/silcutil/silcutil.c.
1573 * Fixed double free in silc_server_command_leave in the file
1576 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Fixed the version checking in the server. Affected file is
1581 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Fixed the configuration data fetching when accepting new
1584 connections in the server. Affected file silcd/server.c.
1586 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Added `sender_entry' argument to the function
1589 silc_server_packet_relay_to_channel so that we can check
1590 whether some destination actually belongs to the same route
1591 the sender belongs (ie, we must not resend the packet to the
1592 sender). Affected file silcd/packet_send.[ch].
1594 * Added `servername' field to the SilcClientEntry in the server
1595 to hold the name of the server where client is from. Affected
1596 file is silcd/idlist.h.
1598 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Moved the channel message encrypting in the router betwen
1601 router connections from silc_server_channel_message to the
1602 silc_server_packet_relay_to_channel since we want to check
1603 whether we have anybody channel before encrypting anything.
1604 Affected files silcd/packet_[receive/send].c.
1606 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Fixed the [AdminConnection] server config section to support
1609 multiple entries. Affected file silcd/serverconfig.c.
1611 * Added support into the server to check the validity of the
1612 incoming connection before executing any KE or authentication
1615 * The connection configuration is now saved to the KE and
1616 connection auth protocol contexts and not fetched anymore in
1617 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1619 * The local hosts listenning address and port is also resolved
1620 now when starting the server. We want to have the socket object
1621 to include the real address and port for the listener. Added
1622 new function silc_net_check_local_by_sock into the files
1623 lib/silcutil/silcnet.[ch].
1625 * Fixed a broadcast bug in server -> do not broadcast if we
1628 * Fixed a routing bug. Do not route broadcast packets ever.
1629 Broadcast packets must be processed always and not routed since
1630 they may be destined to some other host than yourself and thus
1631 would get routed without no good reason. Affected file is
1634 * Added function silc_server_config_is_primary_route to check
1635 whether primary router connection has been configured (a router
1636 configuration that we are initiating). If there is not, we
1637 will assume that there is only two routers in the SILC network
1638 and we will use the incoming router connection as our primary
1639 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1641 * Changed the order of the broadcasting. Broadcast _after_ the
1642 packet has been processed not before. Affected file is
1645 * Fixed a [ClientConnection] parsing bug. The port was never
1646 parsed correctly thus resulting to port 0. Affected file
1647 silcd/serverconfig.c.
1649 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1650 argument and did not set the broadcast packet flag. Affected
1651 file silcd/packet_send.c. Fixed same bug in the function
1652 silc_server_send_notify as well.
1654 * If we receive NEW_ID packet for our own ID in the server, ignore
1657 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * Removed the nickname from the Private Message Payload.
1662 Updated the code and the protocol specs.
1664 * Updated protocol specs for submitting to the IETF.
1666 * Tweaked the Random Number Generator a bit. Affected file
1667 lib/silccrypt/silcrng.c. Exported a new function
1668 silc_rng_[global]_add_noise which can be used to add more
1671 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Do not parse packets with different timeout when protocol
1674 is active -> may cause problem with rekey. Affected file
1677 * When server receives signoff notify it must not create
1678 new channel key if the client is on any channels since the
1679 sender of the signoff notify will create it.
1681 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Added printing of error messages during SKE protocol from the
1684 failure packet sent by server during SKE. Affected file
1687 * Removed the client's failure_callback handling with timeout
1688 and handle it immediately when received.
1690 * The SKE library returned wrong type in SUCCESS and FAILURE
1691 packets. They must be 32 bit MSB not 16 bit MSB.
1693 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1695 * Ok, rewrote the logic of the re-key and now it seems to work.
1696 I tested it on high traffic with frequent re-keys without
1697 problems. Added hmac_receive (and renamed hmac to hmac_send)
1698 in SilcClientConnection in lib/silcclient/client.h and
1699 in SilcIDListData in silcd/idlist.h. Also, removed the
1700 SilcPacketParserContext's cipher and hmac fields as they are
1701 not needed anymore and actually caused some problems when
1702 the ciphers and hmac's changed underneath the packet parser.
1704 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * If re-key protocol is active then process the incoming packets
1707 synchronously since we must assure that icoming packets encrypted
1708 with the old key is processed before the new keys is set to
1709 use. This is true other packets than for REKEY packets.
1710 Affected file silcd/server.c. The same was done to client library
1711 as well, affected file lib/silcclient/client.c.
1713 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Fixed bug in client and server to accept the force send if
1716 the packet is send from silc_[server/client]_packet_process
1717 function. Otherwise the packets are never delivered, oops.
1719 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * Disable force sending of packets when REKEY protocol is active.
1722 We must assure that no packet is sent directly when rekey is
1723 performed. All packets must be sent through packet queue.
1724 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1725 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1726 function is silc_[server/client]_packet_send_real to check
1729 * Replaced the SIM paths from example config files to
1730 /usr/local/modules. Also, make install creates now
1731 /usr/local/silc/logs directory to hold all the SILC server
1734 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Made the configure.in.pre work on Solaris. Patch by salo.
1738 * Made all ciphers compatible with non-x86 machines. Defined
1739 CBC mode macros into lib/silccrypt/ciphers_def.h.
1741 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Fixed the make install.
1745 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * When MAC computation fails the silc_packet_decrypt returned 0
1748 even though it was supposed to return -1. Fixed this. The
1749 affected file is lib/silccore/silcpacket.c.
1751 * Do not replace the config files in /etc/silc (in make install)
1752 if they already exist. Affected file ./Makefile.am.
1754 * Do not send re-key packets immediately but through packet queue.
1755 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1757 * Changed silc_net_check_host_by_sock to return FALSE if the
1758 IP/DNS could not be resolved. Though, it returns the IP address
1759 now even if it could not resolve it (but returns also FALSE).
1760 Affected file lib/silcutil/silcnet.[ch].
1762 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Added silc_pkcs_decode_identifier to decode the public key's
1765 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1766 Added also silc_pkcs_free_identifier. Added also new context
1767 SilcPublicKeyIdentifier.
1769 * Added -S option to the silc client. It is used to dump the
1770 contents of the specified public key file.
1772 * Changed the PKCS api to return the public key length when
1773 setting the public key.
1775 * Fixed a fatal bug in the public and private key file loading.
1776 Affected file lib/silccrypt/silcpkcs.c.
1778 * Execute the packet parsing for client with zero (0) timeout
1779 if the protocol is active. Affected file silcd/server.c.
1781 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1783 * Made the key generation options to the silcd program. Added
1784 -C option, equivalent to client's option.
1786 * Added new [ServerKeys] config section to the server. It
1787 configures the server's public and private key.
1789 * Defined generic Public Key Payload into the protocol
1790 specification to send specific type of public keys and
1793 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1794 public key or certificate.
1796 * Implemented the GETKEY command to the server and to the
1797 client library and on user interface.
1799 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1801 * Made preliminary `make install' work.
1803 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Added SilcServerRekey context into silcd/idlist.h.
1807 * Added the PFS support as defined in the specification to the
1808 SKE protocol. Affected files lib/silcske/*.c.
1810 * Added `ske_group' field to the SilcServerRekey context to hold
1811 the number of the SKE group that is used with PFS in re-key.
1812 Affected file silcd/idlist.h.
1814 * Added PFS re-key support to the server. Affected file is
1817 * Added silc_protocol_cancel to cancel execution of the next
1818 state of the protocol. Affected file is
1819 lib/silccore/silcprotocol.[ch].
1821 * Added the re-key support with and without PFS to the client
1822 library. Re-key is performed once in an hour, by default.
1824 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1825 Added silc_client_rekey_callback and silc_client_rekey_final.
1826 Affected files are lib/silcclient/protocol.[ch] and
1827 lib/silcclient/client.[ch].
1829 * Removed the `hmac_key' and `hmac_key_len' fields from the
1830 SilcClientConnection structure; not needed. Affected file is
1831 lib/silcclient/client.h.
1835 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Do not ask whether user wants to use the negotiated private key
1838 for private messages, just use it. Affected file is
1839 silc/local_command.c.
1841 * Added `send_enc_key' and `enc_key_len' fields to the
1842 SilcIDListData structure since they are needed in the re-key
1843 phase. Affected file is silcd/idlist.[ch].
1845 * Implemented the simple re-key protocol into the server.
1846 Affected files silcd/server.c and silcd/protocol.[ch]. The
1847 re-key will be performed once in an hour, by default.
1849 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1850 Added silc_server_rekey, silc_server_rekey_callback and
1851 silc_server_rekey_final.
1853 * Removed Tunneled flag from the protocol. Updated the code
1854 and the specifications.
1856 * Adde `pfs' field to the SilcIDListData to indicate whether
1857 the PFS is to be performed in the re-key. Affected file is
1860 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1863 int64 of at least the xintXX size. If void * is less that 4
1864 bytes uint32 * will be used. Defined bool as boolean.
1866 * Changed _ALL_ unsigned long and unsigned int to uint32,
1867 unsgined short to uint16 in the source tree.
1869 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1870 not handle clients that has entry->data.registered == FALSE.
1871 They are not in the network anymore. Affected file is
1874 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Implemented the sending of the SERVER_SIGNOFF notify in the
1877 server. Affected file is silcd/server.c.
1879 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1880 Added also silc_notify_payload_encode_args into the
1881 lib/silccore/silcnotify.[ch].
1883 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1884 Affected file silcd/packet_receive.c.
1886 * Implemented the SERVER_SIGNOFF notify handling in the client
1887 library. Affected file lib/silcclient/client_notify.c. Also,
1888 implemnted the printing of the SERVER_SIGNOFF info to the
1889 application. Affected file silc/client_ops.c.
1891 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1892 if the deleting was successful. Affected file silcd/idlist.[ch].
1894 * Added support for public key authentication in the connection
1895 authentication protocol in the client library. Affected file
1896 lib/silcclient/protocol.c.
1898 * Changed the server's silc_idlist_get_clients_by_* interface
1899 to support already allocated array so that new entries may be
1900 added to pre-allocated array. Affected file silcd/idlist.[ch].
1901 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1902 and command replies.
1904 * All command reply functions in the server now calls the
1905 pending command callback even if error occured. This way the
1906 error will be delivered to the client as well. Affected files
1907 silcd/command.c and silcd/command_reply.c.
1909 * Fixed INFO command to return local server's info if no server
1910 was provided. Affected file lib/silcclient/command.c.
1912 * Removed RESTART command for good. Updated the code and the
1915 * Rewrote parts of the task system. It is a bit simpler now.
1916 Removed unsued task priorities. The affected files are
1917 lib/silcutil/silctask.[ch].
1919 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Moved the USERS printing from the library to the application.
1922 Affected files lib/silcclient/command.c and silc/client_ops.c.
1924 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1928 * Added channel key re-key support. The re-key is perfomed
1929 only by the router and is done once in an hour. Added `rekey'
1930 field to the SilcChannelEntry in the server. Affected files
1931 silcd/server.c and silcd/idlist.h.
1933 * Added silc_task_unregister_by_context into the file
1934 lib/silcutil/silctask.[ch].
1936 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Added SILC_UMODE_GONE mode to indicate when the client is not
1939 present in the SILC network. Added also support to the local
1940 command AWAY that will set this mode. Added support of showing
1941 "xxx is gone" in WHOIS command. The USERS command shows the
1942 gone status as well.
1944 * Fixed setting server and router operator privileges in the
1945 server's UMODE command. Affected file silcd/command.c.
1947 * Merged the SKE KE1 and KE2 payloads into one payload. The
1948 new KE payload is equivalent to the old KE2 payload.
1950 Cleaned up the SKE Start Payload parsing. It now uses the
1951 simple buffer unformatting to do the parsing. A lot faster
1954 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1955 to the SKE that is used to indicate whether both of the SKE
1956 parties should perform authentication. By default only the
1957 responder performs authentication. By setting this flag also
1958 the initiator must do authentication. By default it is unset
1959 since in normal SKE case, client to server connection, only
1960 the responder should do authentication. When doing SKE between
1961 two clients both should perform authentication. Updated the
1962 code and the protocol specs.
1964 * A little fix to IDENTIFY command in the server. Search the
1965 client first by hash not nickname. Affected file is
1968 * Fixed the silc_client_close_connection to support closing
1969 the client to client connections wihtout deleting too much
1970 data. Affected file lib/silcclient/client.c.
1972 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1973 are received if protocol used to be active but is not anymore
1974 the application would crash due to NULL pointer dereference.
1975 Affected files silcd/server.c and lib/silcclient/client.c.
1977 * Added `hash' field to the SilcClientConnection to include
1978 the hash function negotiated in the SKE protocol.
1980 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1981 to set the channel founder authentication data. A client can
1982 claim the founder rights later by providing the authentication
1983 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1984 This way the channel founder can regain the channel founder
1985 privileges even it is left the channel. This works only on
1986 local server and the client must be connected to the same
1987 server to be able to regain the founder rights. Updated the
1988 protocol specs accordingly.
1990 Added support to the CMODE command in the client to set the
1991 founder auth data. Read the README to see how to set it.
1993 Added support to the CUMODE command to claim the founder
1994 rights. Read the README to see how to do it.
1996 Added support for the founder authentication to the Channel
1997 Entry in the server. Affected file silcd/idlist.h.
1999 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2000 server's CMODE command. Affected file silcd/command.c.
2002 * Added the following new functions into lib/silccore/silcauth.[ch]:
2003 silc_auth_get_method and silc_auth_get_data.
2005 * The server now saves the remote hosts public key to the
2006 SilcIDListData pointer. Affected file silcd/protocol.c.
2008 * The normal server now does not remove the channel entry from
2009 the cache if the founder authentication data is set. It used
2010 to remove it if the founder was the last one on the channel on
2011 the server and left the channel. The auth data is saved and
2012 if the channel is re-joined later the old entry is used with
2013 the old auth data. Affected files silcd/command_reply.c and
2016 * Removed the `pkcs' field from the SilcIDListData structure
2017 in the server; it is not used. Affected file silcd/idlist.h.
2019 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Fixed packet processing on slow links. Partial packets were
2022 never re-processed because the incoming data buffer was cleared
2023 by the application. Application must not directly clear the
2024 sock->inbuf, the packet processing routines handle it. Fixed
2025 this in client library and in server.
2027 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Fixed the WHOIS and IDENTIFY send reply function to really
2030 check whether to send list or just one entry. Affected file
2033 * Cleaned up the LEAVE command's channel key distribution. The
2034 affected file silcd/command.c.
2036 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2037 can enforce the channel mode as well. In that case the ID
2038 includes the ID of the server. The code now enforces the
2039 mode change if the router have different mode than the server.
2041 * The notify client operation with CMODE_CHANGE notify can now
2042 return NULL client_entry pointer if the CMODE was not changed
2043 by client. Application must check for this.
2045 * Added <Server ID> argument to INFO command to support server
2046 info fetching by Server ID.
2048 * Added silc_server_announce_get_channel_users to get assembled
2049 packets of channel users of the specified channel. Affected
2050 file silcd/server.[ch].
2052 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2053 was freed underneath the ID Cache.
2055 * Re-announce clients when the server received CHANNEL_CHANGE
2056 notify from the router. Affected file silcd/packet_send.c.
2058 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2061 crashed since it did not handle the fact that there is no cipher
2062 called "3" and didn't check the error condition. Now fixed.
2064 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2065 flag. It can be used to send message requests.
2067 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Implemented the RESTART command in the client.
2071 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2072 notice type messages. Added notice printing to the user
2075 * The channel keys are not re-generated if the channel's mode
2076 is PRIVKEY, ie private key on the channel exists. Affected
2077 files silcd/server.c and silcd/command.c.
2079 * Fixed a little bug in channel message delivery when channel
2080 private keys are set in the server. Affected file is
2081 silcd/packet_send.c.
2083 * Changed the setting on channel->on_channel = TRUE from the
2084 silc_client_save_channel_key to the JOIN command reply. The
2085 key payload is not received if the private channel key is set.
2086 Affected file lib/silcclient/command_reply.c and the
2087 lib/silcclient/client_channel.c.
2089 * When the CMODE_CHANGE notify is sent and the channel private
2090 key mode is removed the channel key must be re-generated in
2091 other cells as well. Added this support for the router in the
2092 silcd/packet_receive.c.
2094 * Added new local command NOTICE to send notice message on
2095 channel. Affected file silc/local_command.[ch].
2097 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Added new local command ME to the client. It is used to send
2100 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2101 some action. Affected file silc/local_command.[ch].
2103 * Changed channel_message and private_message client operations
2104 to deliver the message flags to the application. Added also
2105 the `flags' arguments to the silc_client_send_channel_message
2106 and silc_client_send_private_message functions. Affected file
2109 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Redefined the Private Message Payload to support private message
2112 keys and to support the new private message flags. Updated
2113 the protocol specs. Flags makes it possible to have for example
2114 CTCP style messages.
2116 * Added new type SilcPrivateMessagePayload and defined an API
2117 for it in the lib/silcclient/silcprivate.[ch].
2119 * Tested private message private keys successfully. Tested the
2120 private message key set, unset and list commands with the new
2123 * Redefined the Channel Message Payload to include the channel
2124 message flags (equal with private message flags) to support
2125 for example CTCP style messages.
2127 * Defined some of the message (for channel and private message)
2128 flags. Updated the protocol specs and added the flags to the
2129 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2131 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Added SilcKeyAgreementStatus type to the key agreement routines
2134 to indicate the current status and error if one occured.
2135 The status types are defined in the lib/silcclient/silcapi.h.
2137 * Added new local command KEY that is used to set and unset private
2138 keys for channels, set and unset private keys for private messages
2139 with remote clients and to send key agreement requests and
2140 negotiate the key agreement protocol with remote client. The
2141 key agreement is supported only to negotiate private message keys,
2142 it currently cannot be used to negotiate private keys for channels,
2143 as it is not convenient for that purpose.
2145 * Fixed a minor pending callback setting bug in the function
2146 silc_client_get_client_by_id_resolve, now the function works.
2147 Affected file lib/silcclient/idlist.c.
2149 * Added function silc_net_get_local_port to get local bound
2150 port by socket. Added to lib/silcutil/silcnet.[ch].
2152 * Added `sockets' and `sockets_count' fields to the SilcClient
2153 object. They hold the sockets of the listenning sockets in
2154 the client. Listenning sockets may be for example the key
2155 agreement server. Affected file lib/silcclient/client.[ch].
2156 Added functions the silc_client_add_socket and the
2157 silc_client_del_socket. They are exported to the application
2160 * Added ~./silc/clientkeys to support other client's public keys.
2162 * Renamed verify_server_key client operation to verify_public_key
2163 and added one argument to indicate the type of the connection
2164 (server, client etc.).
2166 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Added silc_server_connection_auth_request to handle the
2169 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2170 silcd/packet_receive.[ch].
2172 * Added silc_server_send_connection_auth_request into the
2173 silcd/packet_send.c to send the connection auth request packet.
2175 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2178 * Fixed the public key authentication in responder side in the
2179 server. The `auth_data' pointer includes the SilcPublicKey
2180 not the path to the public key. Affected file silcd/protocol.c.
2182 * Implemented the public key authentication in the initiator side
2183 in the server. Affected file silcd/protocol.c.
2185 * Removed the [RedirectClient] config section from the server
2186 configuration. Is not needed and I don't want to implement it.
2188 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Cleaned up the CMODE command in the server. It now works
2191 correctly and supports all the modes defined in the protocol.
2192 Affected file is silcd/command.c.
2194 * Added `hmac_name' field to the SilcChannelEntry in the server
2195 to hold the default HMAC of the channel. It can be set when
2196 creating the channel (with JOIN command). Affected files
2199 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2200 type to indicate the change of the current cipher and hmac
2201 on the channel. Client can safely ignore the <cipher> argument
2202 (if it chooses to do so) since the CHANNEL_KEY packet will
2203 force the channel key change anyway. The <hmac> argument is
2204 important since the client is responsible of setting the new
2205 HMAC and the hmac key into use.
2207 * Fixed the CMODE command in the client library as well.
2209 * Tested CMODE command in router environment successfully.
2211 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Show the version of the remote client (or server) when connecting
2214 to the server. It is logged to the log file. Affected file
2215 is silcd/protocol.c.
2217 * Fixed the KILLED notify handling in the client library. The
2218 client must be removed from all channels when receiving the
2221 Also, do not remove the client entry when giving the KILL
2222 command but when the KILLED notify is received.
2224 * Removed silc_idlist_find_client_by_nickname from the server.
2225 Not needed anymore. Affected files silcd/idlist.[ch].
2227 * Implemented the CHANNEL_CHANGE notify type handling to the
2228 server. Affected file silcd/server.c.
2232 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Added silc_server_send_notify_invite to send the INVITE
2235 notify between routers.
2237 * Implemented the INVITE command correctly to the server.
2239 * Implemented the INVITE notify type handling in the server.
2241 * Implemented the INVITE command to the client library and on the
2244 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Added function silc_server_get_client_resolve to find the
2247 client entry by ID from all ID lists and then resolve it
2248 (using WHOIS) if it cannot be found. Affected file is
2251 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Implemented the BAN command to the client library.
2255 * The JOIN command in the server now checks the invite list
2258 * Changed the silc_command_reply_payload_encode_va and the
2259 silc_command_payload_encode_va to support that if argument is
2260 NULL it ignores and checks the next argument. Affected file
2261 lib/silccore/silccommand.c.
2263 * Added silc_server_send_notify_ban to send the BAN notify
2264 type between routers.
2266 * Chaned the silc_notify_payload_encode to support that if
2267 argument is NULL it ignores and checks the next argument.
2268 Affected file lib/silccore/silcnotify.c.
2270 * Tested ban lists in router environment successfully.
2272 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Implemented BAN command to the server, in silcd/command.[ch].
2276 * Removed the BAN and INVITE_LIST modes from the CMODE command
2279 * Added function silc_string_match to regex match two strings.
2280 Affected files lib/silcutil/silcutil.[ch].
2282 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Redefined parts of the SilcChannelEntry in the server to support
2285 the new ban and invite lists.
2287 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Redefined the INVITE command. The same command can be used to
2290 invite individuals to the channel but also to manage the invite
2291 list of the channel (to add to and remove from the invite list).
2292 Updated the protocol specs.
2294 * Added new command SILC_COMMAND_BAN that can be used to manage
2295 the ban list of the channel. Updated the protocol specs.
2297 * Removed the channel modes: the SILC_CMODE_BAN and the
2298 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2299 in the CMODE command. The equivalent features are now available
2300 using INVITE and BAN commands. Updated the protocol specs.
2302 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2303 in the network about change in the current ban list. The notify
2304 type is not used by the client.
2306 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2307 support the invite lists.
2309 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Added new function silc_string_regexify that converts string
2312 including wildcard characters into regex string that can
2313 be used by the GNU regex library. Added into the file
2314 lib/silcutil/silcutil.[ch].
2316 Added silc_string_regex_combine to combine to regex strings
2317 into one so that they can be used as one regex string by
2318 the GNU regex library. Added into the file
2319 lib/silcutil/silcutil.[ch].
2321 Added silc_string_regex_match to match two strings. It returns
2322 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2324 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Imported GNU regex to the soruce tree into lib/contrib.
2327 Fixed some compiler warning from the regex.c.
2329 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * Fixed MOTD command in the server to work in router environment.
2333 * Fixed the MOTD command in the client library to support
2334 the server argument in the command.
2336 * Added `nickname_len' argument to the silc_idlist_add_client
2337 in the server, as the `nickname' argument may be binary data
2340 * Added silc_idlist_get_channels to return all channels from
2343 * Implemented LIST command to the server. Affected file is
2346 * Implemented the LIST command to the client library and on the
2349 * Added [<user count>] argument to the LIST command reply.
2350 With private channels the user count is not shown.
2352 * Updated TODO and README.
2354 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * The client entry's data.registered must be TRUE even with
2357 global client entry on global client list. The data.registered
2358 is used to check whether the client is anymore in the network,
2359 for example with WHOWAS command so it must be valid.
2361 * Fixed the WHOWAS command in the server. It now actually works
2362 in router environment. Added function into silcd/command_reply.c
2363 silc_server_command_reply_whowas_save.
2365 * Added silc_idlist_purge function to the silcd/idlist.c
2366 to periodically purge the ID Cache.
2368 * Fixed INFO command in the server. It works now in router
2369 environment. Added <server name> argument to the INFO command
2370 reply. Updated the protocol specs.
2372 * Fixed minor bug in silc_idcache_purge to not purge if the
2373 expire value is zero.
2375 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2376 they were buggy because of the WHOWAS information.
2378 * Fixed local command MSG to handle the async resolving of
2379 the remote client properly. It used to fail the first MSG.
2380 Affected file silc/local_command.c.
2382 * Added `data_len' field to SilcIDCache context.
2384 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Update TODO. Todo in commands in the server.
2388 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2391 used by routers as broadcast packet to inform other routers
2392 about the changed user mode.
2394 Implemented the notify handling in the server. Affected file is
2395 silcd/packet_receive.c. Added the function
2396 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2398 * Added new generic Channel Payload and deprecated the New Channel
2399 Payload. The New Channel Payload is now the generic Channel
2402 * Added new argument `mode' to the silc_server_send_new_channel
2403 as it is required in the Channel Payload now.
2405 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2406 and created a new and real SilChannelPayload to represent the
2407 new generic Channel Payload. Implemented the encode/decode
2408 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2410 * Added silc_server_get_client_channel_list to return the list
2411 of channels the client has joined for WHOIS command reply.
2412 Affected file silcd/server.[ch].
2414 * Implemented the channel list sending in the WHOIS command reply
2415 in server and in the client.
2417 Implemented the channel list displaying on the user interface
2418 as well. Affected file silc/client_ops.c.
2420 * Added silc_channel_payload_parse_list to parse list of Channel
2421 Payloads. It returns SilcDList list of SilcChannelPayloads.
2422 Client for example can use this function to parse the list of
2423 channels it receives in the WHOIS command reply. The caller
2424 must free the list by calling silc_channel_payload_list_free.
2425 Affected files lib/silccore/silcchannel.[ch].
2427 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Added one new argument <user mode> to the WHOIS command reply
2430 to return the mode of the user in SILC. Updated the protocol
2433 Implemented it to the server and client.
2435 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Fixed the mode printing on the user interface on joining.
2438 Affected file silc/client_ops.c.
2440 * Implemented the UMODE command and user modes in general to the
2441 client library and to the user interface.
2443 * Implemented the UMODE command to the server.
2445 * The server now sends UNKNOWN_COMMAND error status if client sends
2446 unknown command. Affected file silcd/command.c.
2448 * All server commands now handle the command identifier the right
2449 way when sending the command reply to the client. The client can
2450 use to identify the command replies with the identifier.
2452 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Added silc_server_get_client_route to resolve the route to
2455 the client indicated by the client ID. Affected file is
2458 * Added silc_server_relay_packet as general function to relay
2459 packet to arbitrary destination. This deprecates functions
2460 like _send_private_message_key, _relay_notify etc. Affected
2461 file is silcd/packet_send.[ch].
2463 Removed silc_server_send_key_agreement,
2464 silc_server_send_private_message_key and
2465 silc_server_packet_relay_notify functions from the file
2466 silcd/packet_send.[ch].
2470 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2471 server. Affected file silcd/packet_receive.[ch].
2473 * Implemented the KILL command to the client. Implemented the
2474 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2475 Affected files lib/silcclient/command[_reply].c and
2476 lib/silcclient/client_notify.c. Implemented the KILL notify
2477 printing in the user inteface.
2479 * Fixed a lot silc_parse_nick memory leaks from the client
2480 library in the file lib/silcclient/command.c.
2482 * Changed the silc_server_send_notify_on_channels's `sender'
2483 argument from SilcSocketConnection to SilcClientEntry to
2484 check the sender as entry and not as connection object and not
2485 to send to the client provided as argument. The affected file
2486 is silcd/packet_send.[ch].
2488 * The notify packets that are destined directly to the client used
2489 to not to be processed by the server. Now changed that and the
2490 server processes all notify packets. After relaying the packet
2491 to the client the notify packet is processed in the server.
2493 * The silc_server_free_client_data now checks whether there is
2494 pending outgoing traffic for the client and purges the data to
2495 the network before removing the client entry.
2497 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2500 an client is killed from the SILC Network. Updated the protocol
2503 Added new function silc_server_send_notify_killed to the
2504 silcd/packet_send.[ch].
2506 * Added function silc_server_packet_relay_notify to relay notify
2507 packets that are destined directly to a client. In this case
2508 the server does not process the notify packets but merely relays
2509 it to the client. Affected file silcd/packet_send.[ch].
2511 Added also silc_server_packet_process_relay_notify to check
2512 whereto relay the notify. Affected file is
2513 silcd/packet_receive.[ch].
2515 * Implemented the KILL command to the server.
2519 * Added the backup schema desgined last fall to the protocol
2520 specs for everyone to see. The specification is in the
2521 *-spec-xx.txt draft and the packet type definitions for the
2522 backup routers is in *-pp-xx.txt draft. Thusly, added also
2523 new packet type SILC_PACKET_CELL_ROUTERS.
2525 * A big security problem in the implementation discovered. The
2526 signoff of an client did not cause new channel key generation
2527 which it of course should've done. The channel keys must be
2528 always re-generated when client leaves (or signoffs) the channel.
2529 The silc_server_remove_from_channels funtion now handles
2530 the channel key re-generation.
2532 * Added `sender' argument to the silc_server_send_notify_on_channels
2533 to not to send the client provided as argument. Affected file
2534 silcd/packet_send.[ch].
2536 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Implemented OPER and SILCOPER commands into the server and
2541 * Added silc_auth_verify and silc_auth_verify_data to verify
2542 the authentication directly from the authentication payload.
2543 It supports verifying both passphrase and public key based
2544 authentication. Affected file lib/silccore/silcauth.[ch].
2546 * Added `hash' field to the SilcIDListData structure. It is the
2547 hash negotiated in the SKE protocol. Affected file is
2550 * Slight redesigning of the SilcAuthPayload handling routines.
2551 Do not send SilcPKCS but SilcPublicKey as argument.
2553 * Implemented the public key authentication support to the
2554 serverconfig. The public key is loaded from the provided path
2555 and saved as authentication data to void * pointer. Thus,
2556 changed the unsigned char *auth_data to void *auth_data;
2558 * Fixed SHUTDOWN command to send the reply before the server
2559 is shutdown. :) Affected file silcd/command.c.
2561 * Fixed fatal bug in CONNECT command. The hostname was invalid
2562 memory and server crashed. Affected file silcd/command.c.
2564 * Fixed fatal bug in CLOSE command. The server_entry became
2565 invalid but was referenced later in the command. Affected file
2568 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Fixed fatal bug in failure packet handling. Server ignored
2571 the failure and thus crashed when it came.
2575 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2578 that the command may be executed only once in (about) 2 seconds.
2579 The old SILC_CF_LAG flag is same but allows command bursts up
2580 to five before limiting.
2582 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2583 server code. Various commands now includes the CF_LAG_STRICT
2584 flag to disallow any kind of miss-use of the command.
2586 * Fixed the silc_buffer_unformat to not to allocate any data
2587 if the length of the data is zero. It used to allocate the
2588 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2590 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Changed the format of AdminConnection configuration section
2593 in the server. Added username of the admin to the format.
2594 Affected files silcd/serverconfig.[ch].
2596 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2597 to return admin configuration data by host, username and/or
2600 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Implemented WHOWAS command to the server. Added the functions:
2604 silc_server_command_whowas_parse,
2605 silc_server_command_whowas_send_reply,
2606 silc_server_command_whowas_from_client and
2607 silc_server_command_whowas_from_server
2609 * Added <Client ID> argument to the WHOWAS command reply. Updated
2610 the protocol specs accordingly.
2612 * Implemented WHOWAS command and command_reply to the client
2615 Implemented the WHOWAS printing on the user interface.
2617 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Added new argument to the WHOWAS command reply, the real name.
2620 It is an optional argument. Updated the protocol specs.
2622 * Added SilcIDCacheDestructor callback that is registered when
2623 the SilcIDCache is allocated. The callback is called when
2624 an cache entry in the ID Cache expires, or is purged from the
2625 cache. Added into lib/silccore/idcache.[ch].
2627 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2628 to destruct the client entries when the cache entry expires.
2629 Other ID Cache's in server and in the client library ignores
2632 * If the ID Cache entry's `expire' field is zero then the entry
2633 never expires. Added boolean `expire' argument to the
2634 silc_idcache_add function in the lib/silccore/idcache.[ch].
2635 If it is TRUE the default expiry value is used.
2637 * Added silc_server_free_client_data_timeout that is registered
2638 when client disconnects. By default for 5 minutes we preserve
2639 the client entry for history - for WHOWAS command.
2641 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Added support to the server to enforce that commands are not
2644 executed more than once in 2 seconds. If server receives
2645 commands from client more frequently, timeout is registered
2646 to process the commands. Affected file silcd/command.c.
2647 Added new function silc_server_command_process_timeout.
2649 * Changed NICK_NOTIFY handling in client library to check that
2650 if the client's nickname was changed, so there is no need to
2651 resolve anything from the server.
2653 * Removed error printing from the WHOIS and IDENTIFY commands.
2654 If error occurs then it is ignored silently in the client library.
2655 The application, however, may map the received error to
2656 human readable error string. The application currently maps
2657 the NO_SUCH_NICKNAME error to string.
2659 * Made the command status message public to the application. Moved
2660 them from lib/silcclient/command_reply.c to
2661 lib/silcclient/command_reply.h. The application can map the
2662 received command status to the string with the
2663 silc_client_command_status_message function.
2665 * Added check to the server to check that client's ID is same
2666 as the Source ID in the packet the client sent. They must
2669 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Added dist-bzip hook to the Makefile.am to make bzip2
2672 compressed distributions.
2674 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Server now enforces the maximum length for the nickname and
2677 the channel as protocol specification dictates. 128 bytes for
2678 nickname and 256 bytes for channel name.
2680 * Moved the WHOIS printing to the application. The client libary
2681 does not print out the WHOIS information anymore, the application
2682 must do it. Renamed silc_client_command_reply_whois_print to
2683 the silc_client_command_reply_whois_save.
2685 The client's idle time is also sent to the application now, and
2686 the idle is shown on screen.
2688 * Added silc_client_command_reply_identify_save to save the
2689 received IDENTIFY entries.
2691 * Do not check for channel private keys in message sending and
2692 reception if the channel does not have the PRIVKEY mode set.
2693 Affected file lib/silclient/client_channel.c.
2695 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2698 just surfaced after chaning the JOIN procedure.
2700 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added silc_client_get_clients_by_list to get client entries
2703 from Client ID list, that is returned for example by JOIN
2704 and USERS command replies. The application should use this
2705 function for example when JOIN command reply is received to
2706 resolve the clients already on the channel (library does not
2707 do that anymore as USERS command reply is not used in the JOIN
2708 procedure anymore). Affected files lib/silcclient/silcapi.h and
2709 lib/silcclient/idlist.c.
2711 * JOIN command reply and USERS command reply returns now SilcBuffer
2712 pointers instead of unsigned char pointers when returning
2713 the client list and mode list.
2715 * Added <Client ID> argument to the JOIN command reply, mainly
2716 for the server to identify for which client the command was
2717 originally sent. Updated protocol specs accordingly.
2719 * Added SilcDlist private_key pointer to the SilcChannelEntry
2720 in the client to support the channel private keys. Affected
2721 file is lib/silcclient/idlist.h.
2723 * Added SilcChannelPrivateKey argument to the function
2724 silc_client_send_channel_message so that application can choose
2725 to use specific private ke if it wants to. If it is not provided,
2726 the normal channel key is used, unless private keys are set.
2727 In this case the first (key that was added first) is used
2728 as the encryption key.
2730 * Implemented the support for channel private key handling.
2731 Implemented the following functions:
2733 silc_client_add_channel_private_key,
2734 silc_client_del_channel_private_keys,
2735 silc_client_del_channel_private_key,
2736 silc_client_list_channel_private_keys and
2737 silc_client_free_channel_private_keys
2739 Affected file lib/silcclient/client_channel.c.
2741 * Added the support for the private keys in the channel message
2742 sending and encryption and in the message reception and
2743 decryption. Affected funtions are
2744 silc_client_send_channel_message and silc_client_channel_message.
2746 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Added SKE's key verify callback to the client library's
2749 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2751 * Removed the statement that server (or router) must send USERS
2752 command reply when joining to the channel so that the client
2753 knows who are on the channel. Instead, the client list and
2754 client's mode list is now sent in the JOIN command reply to the
2755 client who joined channel. This is better solution.
2757 * Added function silc_server_get_users_on_channel and function
2758 silc_server_save_users_on_channel to the silcd/server.[ch].
2760 * Removed function silc_server_command_send_users from the
2763 * Do not show topic on the client library anymore. The topic is
2764 sent in the command reply notify to the application and the
2765 application must show the topic now.
2767 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Added client searching by nickname hash into the IDENTIFY and
2770 WHOIS commands in the server as they were clearly missing from
2771 them. Affected file is silcd/command.c.
2773 * Fixed a bug in private message receiving in the client library.
2774 The remote ID was freed and it wasn't supposed, now it is
2777 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Minor fix to the channel payload; allocate the data area, as it
2780 needs to be of specific length.
2782 * If the key agreement port is zero then the operating
2783 system will define the bound port. Affected files are
2784 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2786 * Added new function silc_channel_payload_decrypt into the file
2787 lib/silccore/silcchannel.[ch].
2789 * Moved the channel message etc, check from silc_packet_decrypt
2790 to applications. The library calls now a generic
2791 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2792 when the packet is either normal or special. This was done to
2793 allow more wide range of checking that was not allowed when
2794 the code was in library. Now applications can do virtually any
2795 checks to the packet and return to the library the decision how
2796 the packet should be processed. Affected files are
2797 lib/silccore/silcpacket.[ch].
2799 Added silc_server_packet_decrypt_check to the server and
2800 silc_client_packet_decrypt_check to the client library.
2802 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2803 to send with specified source and destination information.
2805 * Channel message delivery between routers was broken after the
2806 channel key distribution was fixed earlier. The channel key
2807 was used be to distributed to other routers as well which is not
2808 allowed by the protocol. Now this is fixed and channel keys
2809 really are cell specific and the channel message delivery between
2810 routers comply with the protocol specification.
2812 * Fixed various commands in server to check also the global list
2813 for the channel entry and not just the local list. The affected
2814 file silcd/command.c.
2816 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Added assert()s to buffer formatting and unformatting routines
2819 to assert (if --enable-debug) when error occurs. Affected
2820 file: lib/silcutil/silcbuffmt.c.
2822 * Changed to auto-reconnect to check whether the remote host is
2823 router and register the re-connect timeout if it is. It used
2824 to check that whether we are normal server, but router must do
2825 auto-reconnect with another router as well. Affected file
2828 * Removed the [<key len>] option from CMODE command as the cipher
2829 name decides the key length, nowadays. See the defined ciphers
2830 from the protocol specification.
2832 * Added [<hmac>] option to the CMODE command to define the HMAC
2833 for the channel. Added SILC_CMODE_HMAC channel mode.
2835 * Added [<hmac>] option for the JOIN command so that user can
2836 select which HMAC is used to compute the MACs of the channel
2839 * Added Hmac field to the Channel Message Payload. The integrity
2840 of plaintext channel messages are now protected by computing
2841 MAC of the message and attaching the MAC to the payload. The
2842 MAC is encrypted. Now, it is clear that this causes some
2843 overhead to the size of the packet but rationale for this is that
2844 now the receiver can verify whether the channel message decrypted
2845 correctly and also when private keys are set for the channel the
2846 receiver can decrypt the packet with several keys and check from
2847 the MAC which key decrypted the message correctly.
2849 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2850 lib/silccrypt/silccipher.[ch].
2852 * Added silc_hash_len to return the digest length into the
2853 lib/silcrypt/silchash.[ch].
2855 * Rewrote parts of Silc Channel Payload interface in the
2856 lib/silccore/silcchannel.[ch]. The encode function now also
2857 encrypts the packet and parse function decrypts it.
2859 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Fixed a minor formatting bug in the SKE's key material processing.
2862 It actually might have processed the keys wrong way resulting
2865 * Redefined the mandatory HMAC algorithms and added new algorithms.
2866 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2867 and hmac-md5 truncated to 96 bits. The mandatory is now
2868 hmac-sha1-96. Rest are optional (including the one that used
2869 to be mandatory). Rationale for this is that the truncated HMAC
2870 length is sufficient from security point of view and can actually
2871 make the attack against the HMAC harder. Also, the truncated
2872 HMAC causes less overhead to the packets. See the RFC2104 for
2875 * Added new [hmac] configuration section. The SKE used to use
2876 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2877 is of course wrong. The official names that must be proposed in
2878 the SKE are the ones defined in the protocol specification
2879 (hmac-sha1-96 for example). The user can configure any hmac
2880 using any hash function configured in the [hash] section. At
2881 least, the mandatory must be configured.
2883 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2885 * Added HMAC list to the SKE proposal list. It has now both
2886 hash algorithm list and HMAC list. This makes the protocol
2887 incompatible with previous versions. The SKE now seems to work
2888 the way it is supposed to work, for the first time actually.
2890 * Defined plain Hash algorithms to the protocol specification.
2893 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Implemented support for key agreement packets into the server.
2896 Added functions silc_server_key_agreement and
2897 silc_server_send_key_agreement. Other than these functions,
2898 server has nothing to do with this packet.
2900 * Added support for private message key packets into the server.
2901 Added functions silc_server_private_message_key and
2902 silc_server_send_private_message_key.
2906 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2907 called in the protocol's final callback instead in the END
2908 protocol state. This makes a little more sense and in the same
2909 time in client we can use the same protocol routines for normal
2910 key exchange and to key agreement packet handling as well.
2912 * Added to both client's and server's KE protocol context the
2913 SilcSKEKeyMaterial pointer to save the key material. We will
2914 bring the key material to the protocol's final callback by doing
2915 this. The final callback must free the key material.
2917 * Added SKE's packet_send callback into client's KE protocol
2918 context so that the caller can choose what packet sending function
2919 is used. This way we can use different packet sending when
2920 doing normal SKE when doing key agreement packet handling (in
2921 the key agreement packet handling we do not want to encrypt
2924 * Implemented the responder side of the key agreement routines
2925 in the client. The client can now bind to specified port and
2926 accept incoming key negotiation. The key material is passed
2927 to the application after the protocol is over.
2929 * Implemented the processing of incoming Key Agreement packet
2930 in the client. Added function silc_client_key_agreement to
2933 * Implemented the intiator side of the key agreement routines
2934 in the client. The client can now initiate key agreement with
2935 another remote client. The key material is passed to the
2936 application after the protocol is over.
2938 * Created client_keyagr.c to include all the key agreement
2941 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2942 SILC_TASK_CALLBACK except that it is not static.
2944 * Created client_notify.c and moved the Notify packet handling
2945 from the client.[ch] into that file.
2947 * Created client_prvmsg.c and moved all private message and
2948 private message key routines from the client.[ch] into that file.
2950 * Create client_channel.c and moved all channel message and
2951 channel private key routines from the client.[ch] into that file.
2953 * Changed silc_client_get_client_by_id_resolve to resolve with
2954 WHOIS command instead of IDENTIFY command, in the file
2955 lib/silclient/idlist.c.
2957 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Implemented the SKE's responder side to the Client library.
2961 * When FAILURE is received to the protocol do not trust it
2962 blindly. Register a timeout to wait whether the remote closes
2963 the connection as it should do it, only after that process the
2964 actual failure. This was changed to both client and server.
2966 * Added client_internal.h to include some of the structures
2967 there instead of client.h in lib/silcclient/.
2969 * Added function silc_task_unregister_by_callback to unregister
2970 timeouts by the callback function.
2972 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Some "Incomplete WHOIS info" errors has been appearing on the
2975 log files. Took away the entry->userinfo check from WHOIS
2976 reply sending. The entry->userinfo is now " " if client did not
2977 provide one. I thought this was fixed earlier but something
2978 is wrong still. Let's see if the error still appears.
2980 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Fixed a minor bug in the login when the channel key is
2983 re-generated in the server. It used to generate the key in
2984 wrong order and thus caused problems in the channel traffic.
2986 * Fixed a minor bug in channel key distsribution after
2987 KICK command. The key was not sent to the router even though
2990 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added silc_ske_process_key_material_data as generic routine
2993 to process any key material as the SILC protocol dictates. The
2994 function is used by the actual SKE library but can be used by
2995 applications as well. This relates to the private message keys
2996 and the channel private keys since they must be processed the
2997 same way the normal SILC session keys. The protocol dictates
2998 this. Affected files: lib/silcske/silcske.[ch].
3000 Added also silc_ske_free_key_material to free the
3001 SilcSKEKeyMaterial structure.
3003 * Defined silc_cipher_set_key function to set the key for
3004 cipher without using the object's method function. The affected
3005 files: lib/silccrypt/silccipher.[ch].
3007 * Implemented silc silc_client_add_private_message_key,
3008 silc_client_add_private_message_key_ske,
3009 silc_client_del_private_message_key,
3010 silc_client_list_private_message_keys and
3011 silc_client_free_private_message_keys functions in the
3014 Added functions silc_client_send_private_message_key to send
3015 the Private Message Key payload and silc_client_private_message_key
3016 to handle incoming Private Message Key payload.
3018 * Added Cipher field to the Private Message Key payload to set
3019 the cipher to be used. If ignored, the default cipher defined
3020 in the SILC protocol (aes-256-cbc) is used.
3022 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Removed lib/silcclient/ops.h file.
3026 Redefined parts of the SILC Client Library API. Created new
3027 file silcapi.h that deprecates the ops.h file and defines the
3028 published Client Library API. Defined also private message key
3029 API and channel private key API into the file.
3031 This is the file that the application must include from the
3032 SILC Client Library. Other files need not be included by
3033 the application anymore.
3035 * Added new key_agreement client operation callback and also
3036 defined the Key Agreement library API for the application.
3038 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3041 is used by clients to request key negotiation between another
3042 client in the SILC network. If the negotiation is started it
3043 is performed using the SKE protocol. The result of the
3044 negotiation, the secret key material, can be used for example
3045 as private message key.
3047 Implemented the Key Agreement payload into the files
3048 lib/silccore/silauth.[ch].
3050 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Redefined ciphers for the SILC protocol. Added some new ciphers
3053 and defined the key lengths for the algorithms. Changed the
3054 code accordingly. The default key length is now 256 bits.
3056 * Fixed SKE key distribution function silc_ske_process_key_material
3057 when the key length is more than 128 bits. The default key
3058 length in SILC is now 256 bits.
3060 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3061 to indicate unsupported algorithm.
3063 * Renamed rijndael.c to aes.c and all functions as well.
3065 * Fixed a long standing channel key setting bug in client library.
3066 Weird that it has never surfaced before.
3068 * Fixed bug in channel deletion. If the entire channel is removed
3069 then it must also delete the references of the channel entry
3070 from the client's channel list as the client's channel entry and
3071 the channel's client entry share same memory.
3073 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Implemented CONNECT and SHUTDOWN commands in the client.
3077 * Implemented CLOSE command to the client.
3079 * Added the function silc_idlist_find_server_by_name into the
3080 files silcd/idlist.[ch].
3082 Added the function silc_idlist_find_server_by_conn into the
3083 files silcd/idlist.[ch].
3085 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * DIE command was renamed to SHUTDOWN. Updated the both code
3090 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3091 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3093 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3096 * Added function silc_server_create_connection function to create
3097 connection to remote router. My server implementation actually
3098 does not allow router to connect to normal server (it expects
3099 that normal server always initiates the connection to the router)
3100 so the CONNECT command is only good for connecting to another
3103 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3106 or some other client was kicked from the channel.
3108 Implemented the handling of the notify type to both client
3111 Implemented silc_server_send_notify_kicked to send the KICKED
3112 notify. It is used to send it to the server's primary router.
3114 * Implemented the KICK command into server and client.
3116 * Added `query' argument to the silc_idlist_get_client function
3117 to indicate whether to query the client from server or not if
3120 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3121 to indicate that the client is not channel founder.
3125 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Removed the rng context from SilcPacketContext structure and
3128 changed that the packet routine uses the Global RNG API.
3130 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Added support for quit message that client can "leave" on the
3133 channel when it quits the SILC. It is ditributed inside the
3134 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3136 Added silc_server_free_client_data that will take the
3137 signoff message as argument.
3139 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3141 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Updated parts of the protocol specification to keep it up
3146 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3149 payloads in one packet.
3151 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3152 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3153 use now the new List flag.
3155 * Also deprecated the following packet types: REPLACE_ID,
3156 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3158 * Added list support for Notify packet in server.
3160 * Added silc_server_send_notify_channel_change to send the
3161 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3162 the silc_server_send_replace_id.
3164 * Added silc_server_send_notify_nick_change to send the
3165 NICK_CHANGE notify type. Deprecates the function
3166 silc_server_send_replace_id.
3168 * Added silc_server_send_notify_join to send the JOIN notify type.
3169 Deprecates the function silc_server_send_new_channel_user.
3171 * Added silc_server_send_notify_leave to send LEAVE notify type.
3172 Deprecates the function silc_server_send_remove_channel_user.
3174 * Added silc_server_send_notify_cmode and
3175 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3176 types. Deprecates the silc_server_send_set_mode function.
3178 * Added SERVER_SIGNOFF notify type to indicate that server has
3179 quit. This means that all clients on the channel from that
3180 server will drop. This can be also used when netsplit happens.
3182 Deprecated REMOVE_ID packet type since it is not needed anymore
3185 Added silc_server_send_notify_server_signoff to send the
3186 SERVER_SIGNOFF notify type. Deprecates the function
3187 silc_server_send_remove_id.
3189 Added also silc_server_send_notify_signoff to send the
3190 SIGNOFF notify type.
3192 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3193 SILC protocol from this day on. Changed the protocol
3194 specification as well.
3196 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3197 notify type. It is used between routers to notify about
3198 topic changes on a channel.
3200 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3203 * Partly updated the protocol specification to comply with the
3204 changes now made. It is still though a bit outdated.
3206 * The JOIN notify type now takes one extra argument <Channel ID>.
3207 The packet used to be destined to the channel but now the
3208 JOIN type may be sent as list thus it is impossible to
3209 destine it to any specific channel. By adding this argument
3210 it is again possible.
3212 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Added CREDITS file. The CHANGES and CREDITS file will appear
3215 in the distribution as well.
3217 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3220 types in the server's silcd/packet_receive.c.
3222 * Implemented CMODE and CUMODE to work in router environment.
3224 * Fixed minor encoding and decoding buglet from the
3225 lib/silccore/silcmode.c.
3227 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3230 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3232 * Changed all SilcConfigServer* and silc_config_server* to
3233 SilcServerConfig* and silc_server_config*, respectively.
3236 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Associated the ID (client or server ID) to the Authentication
3239 Payload to avoid any possibility of forging. Updated the
3240 protocol specification and the code accordingly.
3242 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * The RSA key length is now save to the RsaKey context in the
3245 key generation process in lib/silccrypt/rsa.c. The key length
3246 is now used to figure out the maximum size of the block allowed
3247 to be encrypted/signed.
3249 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3250 is equivalent to the silc_mp_mp2bin but does not allocate any
3253 * Changed silc_mp_mp2bin API to take length argument. If it is
3254 non-zero then the buffer is allocated that large. If zero, then
3255 the size is approximated using silc_mp_sizeinbase, which however
3258 * Created Global RNG API which is global RNG that application can
3259 initialize. After initializing, any routine anywhere in the
3260 code (including library) can use RNG without allocating a new
3261 RNG object. This was done to allow this sort of use of the
3262 RNG in code that has no chance to allocate RNG object. All
3263 applications currently allocate this and many routines in the
3264 library use this. Affected file lib/silccrypt/silcrng.[ch].
3266 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3267 it to use the Global RNG API.
3269 * Defined Authentication Payload into protocol specification that
3270 is used during SILC session to authenticate entities. It is
3271 used for example by client to authenticate itself to the server
3272 to obtain server operator privileges.
3274 Implemented this payload into the lib/silccore/silcauth.[ch].
3275 Implemented also routines for public key based authentication
3276 as the new protocol specification dictates.
3278 Moved definitions of different authentication methods from
3279 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3281 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3282 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3283 silc_pkcs_verify_with_hash functions into the file
3284 lib/silccrypt/silcpkcs.[ch].
3286 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * The client entry's userinfo pointer must be always valid.
3289 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3290 will fail since it requires the userinfo. Now, the userinfo
3291 is allocated as "" if actual userinfo does not exist. Actually,
3292 it must exist and it is totally Ok to drop client connections
3293 that does not announce the userinfo. However, we will make
3294 this workaround for now.
3296 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3297 to return the remote port by socket.
3299 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3302 SILC_SERVER_PENDING_EXEC and added an new macro
3303 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3304 data or when error occurs while processing the pending command.
3306 Added new argument `destructor' into silc_server_command_pending
3307 and to the SilcServerCommandPending object. This destructor is
3308 now called after calling the pending callback or if error occurs
3309 immediately. If error occurs the actual pending callback won't
3310 be called at all - only the destructor. The destructor may be
3311 NULL if destructor is not needed.
3313 All this applies for client library code as well. Similar
3314 changes were made there as well for the pending commands.
3316 In the client, the application must now allocate the
3317 SilcClientCommandContext with the silc_client_command_alloc
3320 * Added reference counter to the SilcServerCommandContext. Added
3321 function silc_server_command_alloc and silc_server_command_dup
3324 Same type of functions added to the client library for the same
3327 * Removed the cmd_ident from IDListData away since it is now
3328 global for all connections. It is the command identifier used
3329 in command sending and with pending commands. The affected file
3332 * Added reference counter to the SilcSocketConnection objecet to
3333 indicate the usage count of the object. The object won't be
3334 freed untill the reference counter hits zero. Currently only
3335 server uses this, and client ignores it. The client must be
3336 set to use this too later. The affected files are
3337 lib/silccore/silcsockconn.[ch]. Added also the function
3338 silc_socket_dup to increase the reference counter.
3340 This was mainly added because it is possible that the socket
3341 is removed underneath of pending command or other async
3342 operation. Now it won't be free'd and proper DISCONNECTING
3343 flags, etc. can be set to avoid sending data to connection that
3344 is not valid anymore.
3346 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3347 the connection. After that it sets SILC_SET_DISCONNECTED.
3348 It is, however, possible that the socket data is not still freed.
3349 The silc_server_packet_process now checks that data is not
3350 read or written to connection that is DISCONNECTED. The socket
3351 get's freed when the reference counter hits zero.
3353 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Changed the client operation API: channel_message operation's
3356 `sender' is now the client entry of the sender, not the nickname
3357 and the `channel' is the channel entry, not the channel name.
3359 In the private_message operation the `sender' is now also the
3360 client entry of the sender not the nickname.
3362 Affected file is lib/silcclient/ops.h and all applications
3363 using the client operations.
3365 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Moved the calling of ops->connect() from connect_to_server_final
3368 into receive_new_id functin since that is the point when the
3369 client is actually allowed to send traffic to network. The
3370 affected file is lib/silcclient/client.c.
3372 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3375 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3376 (if needs broadcasting) instead of broadcasting the packets one
3377 by one which would make a burst in the network traffic.
3379 * Added `broadcast' argument to the functions in silcd/server.[ch]
3380 silc_server_create_new_channel[_with_id] to indicate whether
3381 to send New Channel packet to primary router.
3383 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added new function into the silcd/server.[ch] files:
3386 silc_server_create_new_channel_with_id to create new channel with
3387 already existing Channel ID.
3389 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3390 lib/silccore/silcpacket.h. This packet is used t send list of
3391 Set Mode payloads inside one packet. Server uses this to set
3392 the modes for the channels and clients on those channels, that it
3393 announced to the router when it connected to it. The protocol
3394 specification has been updated accordingly.
3396 * The silc_server_new_channel did not handle the packet coming
3397 from normal server as it normally does not send that. However,
3398 when it announces its channels it does send it. Implemented
3399 the support for that.
3401 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3402 into the file lib/silccore/id.h.
3404 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Fixed memory leaks in the functions silc_idlist_del_client,
3407 silc_idlist_del_channel and silc_idlist_del_server in the file
3408 silcd/idlist.c. All of those leaked like a sieve.
3410 * Fixed some small memory leaks in the client's function
3411 silc_client_notify_by_server.
3413 * Added functions into silcd/server.c: silc_server_announce_clients,
3414 silc_server_announce_channels and silc_server_announce_server.
3415 These functions are used by normal and router server to announce
3416 to its primary router about clients, channels and servers (when
3417 router) that we own. This is done after we've connected to the
3420 These functions effectively implements the following packet types:
3421 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3422 and SILC_PACKET_NEW_ID_LIST.
3424 * Added new functions into the silcd/packet_receive.[ch]:
3425 silc_server_new_id_list, silc_server_new_channel_list and
3426 silc_server_new_channel_user_list to handle the incoming
3427 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3429 * Added support of changing Channel ID in the function
3430 silc_server_replace_id. If the server that announces a channel
3431 to the router already exists in the router (with same name but
3432 with different Channel ID), router is responsible to send
3433 Replace ID packet to the server and force the server to change
3434 the Channel ID to the one router has.
3436 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3437 client that the Channel ID has been changed by the router. The
3438 normal server sends this to the client. Client must start using
3439 the new Channel ID as the channel's ID.
3441 Implemented handling of this new type into lib/silcclient/client.c
3442 into the function silc_client_notify_by_server.
3444 * Added new function silc_idlist_replace_channel_id into the files
3445 silcd/idlist.[ch] to replace the Channel ID.
3447 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Call silc_server_command_identify_check always when processing
3450 the IDENTIFY command in silcd/command.c
3452 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3455 send keepalive packets. The packet can be sent by clients,
3456 servers and routers.
3458 Added function silc_socket_set_heartbeat into the file
3459 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3460 If not set, the heartbeat is not performed. The actual
3461 heartbeat is implemented in the low level socket connection
3462 library. However, application is responsible of actually
3465 Added silc_server_send_heartbeat to send the actual heartbeat
3466 packet into silcd/packet_send.[ch]. Server now performs
3467 keepalive with all connections.
3469 * Added silc_task_get_first function into lib/silcutil/silctask.c
3470 to return the timeout task with shortest timeout. There was a bug
3471 in task unregistration that caused problems. TODO has been
3472 updated to include that task system must be rewritten.
3474 * The client library will now resolve the client information when
3475 receiving JOIN notify from server for client that we know but
3476 have incomplete information.
3478 * Rewrote parts of silc_server_remove_from_channels and
3479 silc_server_remove_from_one_channel as they did not remove the
3480 channel in some circumstances even though they should've.
3482 * Encryption problem encountered in server:
3484 The LEAVE command used to send the Channel Key packet to the
3485 router immediately after generating it. However, the code
3486 had earlier sent Remove Channel user packet but not immediately,
3487 ie. it was put to queue. The order of packets in the router
3488 was that Channel Key packet was first and Remove Channel User
3489 packet was second, even though they were encrypted in the
3490 reverse order. For this reason, MAC check failed. Now, this
3491 is fixed by not sending the Channel Key packet immediately but
3492 putting it to queue. However, this is more fundamental problem:
3493 packets that are in queue should actually not be encrypted
3494 because packets that are sent immediately gets encrypted
3495 actually with wrong IV (and thus MAC check fails). So, packets
3496 that are in queue should be encrypted when they are sent to
3497 the wire and not when they put to the queue.
3499 However, the problem is that the current system has not been
3500 designed to work that way. Instead, the packet is encrypted
3501 as soon as possible and left to the queue. The queue is then
3502 just purged into wire. There won't be any fixes for this
3503 any time soon. So, the current semantic for packet sending
3506 o If you send packet to remote host and do not force the send
3507 (the packet will be in queue) then all subsequent packets to the
3508 same remote host must also be put to the queue. Only after the
3509 queue has been purged is it safe again to force the packet
3512 o If you send all packets immediately then it safe to send
3513 any of subsequent packets through the queue, however, after
3514 the first packet is put to queue then any subsequent packets
3515 must also be put to the queue.
3517 Follow these rules and everything works fine.
3519 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Added new function silc_server_remove_clients_by_server to
3522 remove all client entries from ID list when the server connection
3523 is lost. In this case it is also important to invalidate all
3524 client entires as they hold the invalid server entry. This
3525 fixes fatal bug when server has lost connection and will reconnect
3528 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Made some sanity checks to silc_server_daemonise like to check
3531 whether the requested user and group actually exists.
3533 * Added sanity check to SKE's silc_ske_responder_finish to check
3534 that the public and private key actually is valid.
3536 * Invalidate the client's nickname when receiving Replace ID
3537 packet and the Client ID is being replaced. This means that the
3538 server will query the nickname if someone needs it (client)
3541 * Sort the ID Cache in client library when the ID Cache data
3542 has changed (needs sorting).
3544 * Do not allow for SILC client to create several connections to
3545 several servers. The client does not support windows right now
3546 and generating multiple connections causes weird behaviour.
3548 Irssi-silc client does support windows and can handle several
3549 connections without problems, see: www.irssi.org and SILC plugin.
3551 * Fixed some places where client was added to the IDList. The
3552 rule of thumb is following (in order to get everything right):
3553 If the client is directly connected local client then the
3554 `connection' argument must be set and `router' argument must be
3555 NULL to silc_idlist_add_client function. If the client is not
3556 directly connected client then the `router' argument must
3557 bet set and the `connection' argument must be NULL to the
3558 silc_idlist_add_client function.
3560 * The funtion silc_server_packet_send_local_channel actually did
3561 not check whether the client was locally connected or not. It
3562 does that now. Fixed a bug related to LEAVE command.
3564 * Fixed Remove Channel User payload parsing bug in server's
3565 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3567 * The server's silc_server_save_channel_key now checks also the
3568 global ID list for the channel as it might not be in the local
3569 list. Fixed a bug related to LEAVE command.
3571 * Is this the end of the [<unknown>] buglet that has been lurking
3572 around for a long time? A little for loop fix in server's
3573 silc_server_command_whois_parse that is used by both IDENTIFY
3574 and WHOIS command. At least, this was a clear bug and a cause
3575 of one type of [<unknown>] buglet.
3577 * WHOIS and IDENTIFY commands call the function
3578 silc_server_command_[whois/identify]_check function even if
3579 we are not router server.
3581 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Added --with-gmp configuration option. If set the GMP
3584 is always compiled in the SILC source tree. If not set then
3585 it is checked whether the system has the GMP3 installed. If
3586 it has then the GMP won't be compiled (the system's headers
3587 and library is used), if it doesn't have it then the GMP is
3588 compiled in the SILC source tree.
3590 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Changed RSA private exponent generation to what PKCS #1
3593 suggests. We try to find the smallest possible d by doing
3594 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3595 not security fix but optimization.
3597 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Added new config entry [Identity] to fork the server and run
3600 it as specific user and group. A patch from Bostik.
3602 * Imported Dotconf configuration library into lib/dotconf.
3603 This will be used to create the SILC configuration files later.
3604 It will appear in the distsribution after this commit.
3606 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * A big code auditing weekend happening. Auditing code for
3609 obvious mistakes, bugs and errors. Also, removing any code
3612 Removed files for being obsolete:
3614 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3615 inline in the file lib/silcutil/silcbuffer.h)
3617 o lib/silcutil/silcbufutil.c (the header has inline versions)
3619 Changed code to fix possible error conditions:
3621 o The buffer formatting routines now check that the destination
3622 buffer really has enough space to add the data. This applies for
3623 both buffer formatting and unformatting
3624 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3625 unformatting was changed to accomodate following rules:
3626 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3627 sent to the function while XXX_*STRING will not allocate or copy
3628 the data into the buffer. Instead it sets the pointer from the
3629 buffer into the pointer sent as argument (XXX_*STRING used to
3630 require that the pointer must be allocated already). This change
3631 makes this whole thing a bit more consistent and more optimized
3632 (note that the data returned in the unformatting with XXX_*STRING
3633 must not be freed now). The routines return now -1 on error.
3635 o Tried to find all code that use buffer_format and buffer_unformat
3636 and added return value checking to prevent formatting and
3637 especially unformatting errors and possible subsequent fatal
3640 o Changed ske->x and ske->KEY to mallocated pointers in
3641 lib/silcske/silcske.h. Fixed possible data and memory leak.
3643 o Added return value checking to all *_parse* functions. Fixed
3644 many memory leaks as well.
3646 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3647 so that buffer overflows would not happen. All code now also
3648 checks the return value as it can fail.
3650 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added reconnection support to server if the normal server looses
3653 its connection to the router (for example if router is rebooted).
3654 The server performs normal reconnection strategy implemented
3655 to the server. Affected file silcd/server.c.
3657 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Added new packet type SILC_PACKET_SET_MODE that is used to
3660 distribute the information about changed modes (for clients,
3661 channels and clients channel modes) to all routers in the
3662 network. Updated the protocol specification accordingly.
3664 Added functions into silcd/packet_send.c and
3665 silcd/packet_receive.c: silc_server_send_set_mode,
3666 silc_server_set_mode.
3668 Added new files silcmode.[ch] into lib/silccore that implements
3669 the encoding and decoding of Set Mode Payload. Added new type
3670 SilcSetModePayload. Moved the definitions of different modes
3671 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3673 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Oops, a little mistake in server's connection authentication
3676 protocol. The protocol is not ended with FAILURE but with
3677 SUCCESS if the authentication is Ok. :) Affected file is
3680 * Implemented NICK_CHANGE notify handling in server in the file
3681 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3682 the local clients on the channel. After the changing nickname
3683 in router environment snhould work and the [<unknown>] nickname
3684 should appear no more.
3686 The silc_server_replace_id function that receives the Replace ID
3687 payload now sends the NICK_CHANGE notify type also in the file
3688 silcd/packet_receive.c
3690 * Changed WHOIS and IDENTIFY command to support the maximum amount
3691 of arguments defined in protocol specs (3328 arguments). This
3692 fixed a bug that caused problems when there were more than three
3695 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Added extra parameter, command identifier, to the
3698 silc_client_send_command so that explicit command identifier
3701 Changed that ID list routines uses specific command identifier
3702 when sending WHOIS/IDENTIFY requests to the server so that they
3703 can be identified when the reply comes back.
3705 Affected files lib/silcclient/command.[ch],
3706 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3708 * Added `sender' argument to silc_server_packet_send_to_channel
3709 to indicaet the sender who originally sent the packet to us
3710 that we are now re-sending. Ignored if NULL. Affected file
3711 silcd/packet_send.[ch].
3713 * Added some server statistics support in silcd/server_internal.h
3714 SilcServerStatistics structure and around the server code. Also
3715 send some nice statistics information when client is connecting
3718 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Fixed channel ID decoding in server's JOIN command reply in
3721 silcd/command_reply.c
3723 * Fixed braodcasting of replace ID payload to not to send it if
3724 we are standalone server in silcd/packet_receive.c.
3726 * Fixed all channel message sending routines to not to send
3727 packets to clients that has router set, since they are routed
3728 separately in the same function earlier. Affects file
3729 silcd/packet_send.c and all channel packet sending functions.
3731 * In USERS reply, res_argv[i] are not allocated, the table
3732 is allocated. Thus changed that free the table, not its
3735 * In server's whois_check and identify_check if the client is
3736 locally connected do not send any WHOIS commands - they are not
3739 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Fixed some minor bugs in client when sending WHOIS command. The
3742 arguments was in wrong order.
3744 * Removed statis function add_to_channel from server in
3745 silcd/command.c that was previously used with the joining but
3748 * Tested USERS command in router environment successfully with two
3749 routers, two servers and two clients.
3751 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Reorganized the USERS command and command reply in client library
3754 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3755 When the command is given by user we register a pending command
3756 callback that will reprocess the command after the reply has been
3757 received from the server. When reprocessing the packet we then
3758 display the information. Thus, the USERS information is displayed
3759 now in the command callback instead of in the command reply
3760 callback. The processing of the command is same as previously
3761 when server has sent the command reply in the JOINing process.
3763 * Added to USERS command in silcd/command_reply.c to join the client,
3764 we didn't use to know about, to the channel after we've created
3765 a client entry for it. Also, for clienet we did know already still
3766 check whether it is on the channel or not and add it if not.
3768 * Removed silc_server_command_join_notify as the function and its
3771 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Changed the client's pending command handling to the same as the
3774 server's pending command handling. It is also now possible to
3775 execute command reply functions from other command reply
3776 function as the function callbacks for commands and command
3777 replies are one and same. The pending commands are not static
3778 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3779 in client connection context. Thus, pending commands are server
3780 connection specific as it is convenient.
3782 Changed the function silc_client_command_pending and
3783 silc_client_command_pending_del and added new function
3784 silc_client_command_pending_check. Removed the
3785 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3788 * Added cmd_ident, current command identifier, to the client
3789 connection context in lib/silcclient/client.h to keep track on
3790 command identifiers used in command sending. Client's command reply
3791 function handling now supports the mandatory command identifiers.
3793 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3794 funtions in client to fully support pending command callbacks.
3796 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3797 as one of the arguments to the application in the command reply
3800 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3801 before first releasing SILC but came back. Now it is removed again
3802 and should come back nomore. The FORWARDED flag was used only
3803 by the JOINing procedure by forwarding the command packet to router.
3804 Now, the JOINing procedure has been changed to more generic (due
3805 to various router environment issues) and FORWARDED is not needed
3806 anymore for anything. The protocol specification is yet to be
3809 Now, removed silc_server_packet_forward from server and the flag
3810 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3812 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Renamed NAMES command to USERS command. The NAMES was named that
3815 due to historical reasons. Now it is renamed. Also, rewrote
3816 parts of the USERS command. The nickname list is not sent anymore
3817 by the server. Only Client ID and mode lists are sent in the USERS
3818 command. Changed this also to the protocol specification.
3820 The client now resolves the names and stuff after it receives
3821 the USERS list from the server when joining to the channel.
3823 * WHOIS and IDENTIFY commands has been changed to support multiple
3824 Client ID's per command. One can now search for multiple users
3825 in the network by sending only one WHOIS or IDENTIFY command.
3826 Changed the code and the protocol specifications.
3828 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3829 uses silc_server_command_whois_parse to parse the request. */
3831 * If normal server, do not parse the WHOIS and IDENTIFY requests
3832 before sending it to the router. Saves some time.
3834 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Fixed JOIN command on client library. Wrong number of arguments
3837 used to crash the client.
3839 * Added silc_server_channel_has_global function to check whether
3840 channel has global users or not.
3842 * Added silc_server_channel_has_local function to check whether channel
3843 has locally connected clients on the channel.
3845 * The silc_server_remove_from_one_channel now checks whether the
3846 channel has global users or not after given client was removed from
3847 the channel. It also checks whether the channel has local clients
3848 on the channel anymore. If it does not have then the channel entry
3849 is removed as it is not needed anymore.
3851 * The silc_server_notify now checks on JOIN notify whether the joining
3852 client is one of locally connected or global. If it is global then
3853 the channel has now global users on the channel and that is marked
3854 to the channel entry. Also, it now saves the global client to
3855 global list who is joining and JOINs it to the channel. This is
3856 for normal server, that is.
3858 Changed silc_server_send_notify_on_channel,
3859 silc_server_packet_relay_to_channel and
3860 silc_server_packet_send_to_channel check if we are normal server
3861 and client has router set (ie. global client) do not send the
3862 message to that client, as it is already routed to our router.
3864 * Implemented LEAVE notify type handling in silc_server_notify
3867 * Tested LEAVE command in router environment successfully. Tested
3868 with two routers, two servers and two clients.
3872 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3874 * Implemented SIGNOFF notify type handling in silc_server_notify
3877 * silc_server_remove_id now removes the client entry from all channels
3878 it has joined and thusly sends SIGNOFF notify type.
3880 * Rewrote the NAMES list generation in server by removing two excess
3881 loops. The lists are created now inside one loop.
3883 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * silc_server_remove_channel_user checks now also global list
3886 for channel and client.
3888 * silc_server_new_channel_user checks now both local and global
3889 list for channel and client. Fixed a bug in client id decoding.
3890 Used to decode wrong buffer.
3892 * silc_server_channel_message checks now both local and global
3893 list for channel entry.
3895 * Tested channel joining (hence JOIN) in router environment
3896 successfully. Tested with two routers, two servers and two
3899 * Tested channel message sending in router environment successfully.
3901 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Added silc_server_save_channel_key into server.[ch] to save the
3904 received channel key in Channel Key payload processing. It is
3905 also used in JOIN command reply handling.
3907 Equivalent function silc_client_save_channel_key added into
3908 client.[ch] into client library.
3910 * Changed JOIN command reply to send information whether the channel
3911 was created or not (is existing already) and the channel key
3912 payload. Changed protocol specs accordingly.
3914 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3915 the request was sent by ID and not by nickname. Crashed on
3918 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3921 now correctly save the received data.
3923 * silc_server_free_sock_user_data now notifies routers in the
3924 network about entities leaving the network.
3926 At the same time implemented functions silc_server_remove_id
3927 and silc_server_send_remove_id to receive and send REMOVE_ID
3928 packets. The packet is used to notify routers in the network
3929 about leaving entities. The ID removed will become invalid in
3932 * Added function silc_idlist_del_server into server. Removes and
3933 free's server entry from ID list.
3935 * silc_server_private_message function now checks, if we are router,
3936 that the destination ID really is valid ID, naturally.
3938 * In router when NEW_ID packet is received (for new client) the
3939 hash of the Client ID is saved in the ID Cache but the
3940 client->nickname is set to NULL, instead of putting the hash
3943 IDENTIFY command now also checks that client->nickname must be
3944 valid. If it is not if will request the data from the server who
3945 owns the client. Added new function
3946 silc_server_command_identify_check.
3948 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3949 to set the command to already allocated Command Payload.
3951 * Tested private message sending in router environment with two
3952 routers, two servers and two clients. Fixed minor bugs and now
3955 * Fixed segfault from client's NAMES command. Used to crash if
3958 * Forwarded packets must not be routed even if it is not destined
3959 to the receiver. Changed server code comply with this.
3961 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Added `require_reverse_mapping' boolean value to ServerParams
3964 structure. If TRUE (not default) the server will require that
3965 the connecting host has fully qualified domain name.
3967 If the reverse mapping is not required and hostname could not be
3968 found the IP address is used as hostname.
3970 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Implemented version string checking to both client and server.
3973 The check is incomplete currently due to the abnormal version
3974 strings used in development version of SILC.
3976 * Changed all command functions in server to use the new
3979 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Changed char *data to unsigned char *data in ID Cache system to
3982 support binary data as ID Cache data. Changed code to support
3983 binary data in lib/silccore/idcache.c.
3985 * Renamed silc_server_packet_relay_command_reply to
3986 silc_server_command_reply as it is normal packet receiving
3987 function. Rewrote the function to accept command replys for
3988 servers and not only for clients.
3990 * Mark remote router always as registered server if we are connecting
3991 to it. Otherwise, commands sent by the router to us are ignored.
3993 * All ID List find routines now returns the ID Cache Entry pointer
3994 as well if requested.
3996 * WHOIS command works now in router environment, tested with two
3997 routers, two servers and two clients.
3999 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4000 in router environment (as it is almost equivalent to WHOIS) but
4001 hasn't been tested thoroughly. Added new functions:
4003 silc_server_command_identify_parse
4004 silc_server_command_identify_send_reply
4005 silc_server_command_identify_from_client
4006 silc_server_command_identify_from_server
4008 * Disabled route cache adding because adding two different ID's with
4009 same IP replaces the old cache entry thus giving wrong route.
4010 The entry->router->connection is always the fastest route anyway
4011 so route cache may not be needed. Of course, new routes maybe
4012 established after receiving the ID when the entry->router->connection
4013 might not be anymore the most optimal.
4015 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Add route cache for received ID for fast routing.
4019 * Added silc_server_packet_route to route received packet on router
4020 that is not destined to us.
4022 * Renamed silc_server_get_route to silc_server_route_get.
4024 * Added id_string and id_string_len fields into SilcServer to
4025 include encoded ServerID for fast comparing without excess
4026 encoding of the ID's.
4028 * Cleaned up WHOIS command on server side. Added following static
4031 silc_server_command_whois_parse
4032 silc_server_command_whois_check
4033 silc_server_command_whois_send_reply
4034 silc_server_command_whois_from_client
4035 silc_server_command_whois_from_server
4037 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4038 arguments in command replies. All command functions should be
4039 updated to use this macro.
4041 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Minor typo fixes on command reply handling on server.
4045 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Added silc_server_command_add_to_channel internal routine to add
4048 the client to the channel after router has created the channel and
4049 sent command reply to the server.
4051 * Added generic silc_server_send_command to send any command from
4054 * Use static buffer with ID rendering instead of duplicating data.
4056 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Fixed a channel user mode bug when joining to a channel server gave
4059 everybody channel founder rights, oops.
4061 * We mark ourselves as the router of the incoming server connection
4062 if we are router ourselves. This way we can check in some packet
4063 sending functions whether it is locally connected server. For
4064 incoming router connections we put NULL.
4066 * For router sending packets locally means now always sending the
4067 packet cell wide; to local clients and local servers. For normal
4068 server sending packet locally means sending it to only local
4071 * Fixed the JOIN command to really work in router environment. If the
4072 channel is created it is always created by the router. Router is
4073 also responsible of making the initial joining to the channel,
4074 sending JOIN notify to the sending server and distributing
4075 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4076 does not exist server doesn't do anything else but forward the
4077 command to the router which performs everything.
4079 * Added silc_server_send_channel_key function to send the Channel Key
4082 * Added silc_server_create_channel_key to create new channel key. The
4083 channel key is now re-generated everytime someone joins or leaves
4084 a channel, as protocol dictates. Note: channel->key_len is the
4087 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4090 packet_receive.[ch] to separate packet sending and receiving
4091 routines. The server.[ch] now includes everything else including
4092 actual packet processing (writing and reading data) and other
4095 Renamed silc_server_private_message_send_internal to
4096 silc_server_send_private_message. The routine is still though
4097 used only to relay private messages as server does not send
4098 private messages itself.
4100 Renamed silc_server_new_channel to silc_server_create_new_channel
4101 and added new function sicl_server_new_channel that handles the
4102 incoming New Channel packet. Added also new sending function
4103 silc_server_send_new_channel to send New Channel Payload.
4105 * Added new function silc_server_notify to process incoming notify
4106 packet to the server/router. Server may then relay the notify
4107 to clients if needed.
4109 * Added new function silc_server_new_channel_user to process incoming
4110 New Channel User packet. Router will redistribute the packet and
4111 send JOIN notify to its local clients and locally connected servers
4112 if needed. Normal server will send JOIN notify to its local client
4113 on same channel when received this packet. Added also corresponding
4114 sending function silc_server_send_new_channel_user to sent the
4117 * Added boolean route argument to send_notif_to_channel and
4118 packet_send_to_channel functions to attempt to route the packet
4119 if it is TRUE and send only locally if it is FALSE.
4121 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * silc_server_replace_id now broadcasts the received replace ID
4124 packet if it is not broadcast packet already. The router must
4125 broadcast to inform other routers about changed ID.
4127 * Added backpointer to server's router into SilcServer context in
4128 silcd/server_internal.h.
4130 * Fixed silc_server_packet_broadcast to send correct broadcast
4133 * The channel key is now distributed to the local client as soon
4134 as it is received from the router (in router environment) so that
4135 no other packet may be sent for the channel until client has
4138 * silc_server_remove_channel_user now broadcasts the received
4139 Remove Channel User packet if it is not broadcast packet already.
4140 The router must broadcast to inform other routers about removed
4143 * Added users field into SilcPacketContext that is a reference count
4144 of the context. One can increase the reference count by calling
4145 silc_packet_context_dup which is now changed to just increase the
4146 reference count instead of duplicating the data. The reference
4147 count is decresed by calling silc_packet_context_free that will
4148 free the data after the reference count hits zero.
4150 For now on the packet context and everything allocated into it
4151 (including the raw packet from network) must be freed by calling
4152 the new silc_packet_context_free function. Added also new function
4153 silc_packet_context_alloc that must be used now to allocate the
4154 context. This also means that if a routine is asynchronous from
4155 silc_[client/server]_packet_parse_type the packet context must
4156 be duplicated by calling silc_packet_context_dup. Otherwise it
4157 gets free'd after silc_[client/server]_packet_parse_type returns.
4158 Also, one must remember that if packet is duplicated then its
4159 reference count must be decresed by calling the free function as
4160 many times as it was duplicated.
4162 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4163 from both client and server.
4165 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Made joining to a channel working in router environment.
4169 * Cleaned up JOIN command on server side and create function
4170 silc_server_command_join_channel internal routine to make the
4173 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Changed silc_command_pending list to SilcDList. Also, added
4176 `ident' field to SilcServerCommandPending structure to identify
4177 the reply and to call correct callback.
4179 Added silc_server_command_pending_check function to replace the
4180 corresnponding macro. The silc_command_pending list is not
4183 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4184 to set identifier to previously allocated Command Payload. It
4185 is used to set identifier for command when resending Command
4188 * Added silc_command_payload_encode_payload to encode Command
4189 Payload buffer from SilcCommandPayload structure.
4191 * Added silc_argument_payload_encode_payload to encode Argument
4192 payload buffer from SilcArgumentPayload structure.
4194 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Changed WHOIS command to support router connection on server side.
4197 The whois request is always sent to router unless the server is
4198 standalone server. After server has received the reply from the
4199 router will it send the reply to the client.
4201 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4202 broadcast received broadcast packet. The function is used only
4203 by router. The broadcast packet is always sent to the router's
4206 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4207 render given ID to printable string, for log files for example.
4209 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Made basic router to router connections working. At least they
4212 can now connect to each other but nothing really works the way
4213 they are supposed - yet.
4215 * Added new initiator token to RouterConnection configuration
4216 file in silcd/serverconfig.[ch]. It is used to tell whether we
4217 are the initiator to the remote router or whether we'll expect
4218 the other end to connect.
4220 * Moved registering of listener task to silc_server_init, hence
4221 the server starts listenning as soon as it is run, even if it
4222 does not have connections to other routers. Let's see how well
4225 * Changed default connection retry timeouts for more suitable in
4228 * Removed cipher and such arguments from silc_idlist_add_client
4229 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4230 Added new function silc_idlist_add_data to add the keys and stuff
4233 * Added SilcIDListData structure and added it to SilcClientEntry
4234 and SilcServerEntry as their first field in the structure. This
4235 way we can explicitly cast the ID entries to the SilcIDListData
4236 structure and get common data for the entries. In past, we had
4237 to first check what type of connection it is and then cast it to
4238 correct ID entry type. Now, we can directly cast the opaque
4239 pointer to the SilcIDListData (no matter what ID entry it actually
4240 is) and get the data needed.
4242 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4245 in some circumstances even if threre were timeout tasks, though not
4246 IO tasks, but tasks anyway. Now fixed.
4248 * Defined SilcServerConnection structure to hold connection specific
4249 stuff about directly connected servers and routers. The definition
4250 is currently in silcd/server_internal.h. I thought about having
4251 a bit more important role fro this struct but for now it is used
4252 only when connecting to other server (or router actually).
4254 * Added connecting retry support in server when connecting to
4255 router(s). The retry feature implement exponential backoff
4256 algorithm. Also, added SilcServerParams structure to hold default
4257 parameters for server. For now, it include these retry settings
4258 and are hard coded. After server is moded to be as Silc Server
4259 Library this structure will be more important.
4261 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Changed client librarys channel->clients table to SilcList and
4264 changed code accordingly.
4266 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Changed client's channel table to SilcList and changed code
4269 accordingly. Also changed SilcChannelClientEntry to include back-
4270 pointer to the channel so that client entry can use that structure
4271 as list as well and we have fast cross-reference to the channel.
4272 This change dramatically decreased the complexity of channel
4273 handling with client entry and vice versa (removed one extra
4274 loop when searching for channel entry from many functions).
4276 * Changed server->sim from table to SilcDList and changed code
4279 * NAMES command can now be used from user interface. It will show
4280 the user list on the channel, neatly.
4282 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4283 Code now saves realname of the user if it becomes available.
4285 * Renamed configure.in to configure.in.pre and made ./prepare
4286 script to automatically add correct version string to
4287 configure.in which it creates from configure.in.pre.
4289 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * NAMES command reply now shows users mode with the nickname when
4294 * Moved silc_client_ch[u]mode[_char] functions from
4295 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4296 place sucks, they are utility functions and should be in some
4299 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4301 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4304 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Added TRQ (efficient deque and list library) into lib/trq. This is
4309 a very good list library that is currently used in the SILC. Defined
4310 SilcList API over the library because I didn't like the API very
4311 much. See lib/trq/silclist.h for the API and examples of how to
4312 use the API. Fixed various places in the code to use the new
4313 SilcList API. The SilcList is meant for lists that has a structure
4314 already defined as a list. It is not suitable to add just some
4315 context to the list (in TRQ, the context is the list actually).
4317 So, I defined SilcDList that can be used for the purpose where
4318 predefined list structure does not exit. This can be used as
4319 such list. Now some context just can be added to the SilcDList.
4320 Currently this list is not used in the SILC just yet, though there
4321 are a lot places where this can replace dynamically allocated
4322 tables and I will fix these places, later, to use SilcDList.
4323 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4324 and use TRQ internally).
4326 Also fixed some annoying warning messages that the original TRQ
4327 code generated. Also minor changes to TRQ's Makefile.in.
4329 * Added support for querying by Client ID to both WHOIS and
4330 IDENTIFY commands into server, as required by the protocol.
4332 * Removed method function pointers from SilcBuffer structure. They
4333 weren't used to anything and just increased the context size for
4334 no good reason. This change also made silc_buffer_alloc and
4335 silc_buffer_free functions inline functions.
4337 * Disabled command flooding detection support until it's fixed so
4338 that it accepts commands in but does not execute them more than once
4341 * Added silc_net_localhost(), to return local hostname, into
4342 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4343 that must be initialized before calling silc_client_init.
4345 * Added new function: silc_server_send_notify_on_channels to send
4346 notify messages to all channels client has joined. It is assured
4347 that the message is sent only once per client.
4349 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4350 lib/silcutil/silcutil.[ch] as silc_format function. The new
4351 function is generic and is used by server as well, not only by
4352 the logging routines.
4354 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4355 the provided version string was not acceptable. Added new function:
4356 silc_ske_check_version into lib/silcske/silcske.h. The function
4357 must be implemented by the application (client or server) and it
4358 does not reside in the SKE library. The function checks the version
4359 string remote end sent.
4361 * Added back pointers (to opaque context and to SilcSocketConnection)
4362 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4364 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4365 duplicate packet context structure.
4367 * Changed `notify' client operation to send same arguments as client
4368 receives from server except for ID's. ID's are mapped to correct
4369 ID entry and that is returned. Also, if channel entry is not sent
4370 by server but the notify is for channel the channel entry is sent
4371 to application (otherwise application doesn't know that it is for
4372 channel (library gets it from packet's Destination ID)).
4374 * Added silc_client_remove_from_channels into client library to
4375 remove a client from all channels it has joined to. Used when
4376 received SIGNOFF notify from server. Added also new function
4377 silc_client_replace_from_channels to replace old ID entry with
4378 new ID entry on all channels. Used when received NICK_CHANGE
4381 * Fixed ID Cache list handling in silc_idlist_get_client in
4382 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4383 to get (or query) client by ID.
4385 * Updated TODO list.
4387 * Added connection authentication status message defined by the
4388 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4389 support for these into the code in client and server side.
4391 * Added generic function silc_client_send_command to send any command
4392 with variable argument list. Application should use this function
4393 to send commands if the command functions provided by the library
4394 does not suite for the application's user interface needs.
4396 * Added new `failure' client operation. Application is notified about
4397 received failure packet if client is executing a protocol. In this
4398 case the protocol's execution has failed.
4400 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4401 is required by the protocol.
4403 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4404 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4407 * Added status flag to SilcSKE object to indicate realtime status
4408 of the SKE protocol.
4410 * Application receives now exactly same command reply arguments as
4411 the library receives from server. However, if ID is received the
4412 corresponding ID entry is returned to the application (eg. Client
4413 ID is mapped to correct SilcClientEntry entry and that is returned).
4414 Changed command_reply client operation due to this change.
4416 * Changed all ID's in commands and in command replys as ID Payloads.
4417 Change affected both client and server side codes.
4419 All ID's sent in SILC network (with execption of ID's in SILC
4420 Packet header) are sent in ID Payload to support variable length
4423 * Server now notifies nick changes and notifies all clients on
4424 the channels about the new nickname (about the new Client ID,
4427 * Implemented CMODE command to change channel modes. Supports all
4428 channel modes defined by the protocol specs except ban and invite
4429 lists. (Also, private channel key mode is supported but support for
4430 setting private channel key in client is missing, thus, this mode
4431 has no effect on client side (except that server requires that the
4432 client uses private channel key and normal channel traffic does not
4435 Also, invite mode works per se, but INVITE command does not work
4436 yet correctly, so you can set channel as invite only channel but
4437 inviting clients to the channel does not work (it is yet to be
4438 thought what's the best way to do it).
4440 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4441 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4442 Implemented CUMODE command to change user's mode on the channel.
4443 Supports all modes defined by the protocol specs.
4445 * Added NAMES command reply to return users modes on the channel.
4447 * Removed unnecessary and slow ciphers from lib/silccrypt.
4449 * Set SO_KEEPALIVE option to connection sockets by default.
4451 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4453 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4454 redefined the Notify Payload into protocol specs.
4456 * Added silc_id_payload_parse_id to get ID directly from raw
4459 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4462 accept searching by Client ID as well.
4464 * Added support for LEAVE and SIGNOFF notify types in client library.
4466 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4467 to parse ID Payload from raw data.
4469 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added flags parameter into silc_ske_assemble_security_properties
4472 function in lib/silcske/silcske.[ch].
4474 * Changed notify client operation to fit better for notify messages
4475 sent by server. The notify payload received from server is now
4476 passed to the application (after parsing it to SilcNotifyPayload).
4477 It is application's responsibility to retrieve the arguments
4478 from the payload and show the message the way it wants. The message
4479 sent by server is implementation specific.
4481 * Changed public keys to comply with the protocol specification.
4482 Old public keys are not supported anymore and are not compatible.
4484 * Removed nickname from Channel Payload as the latest draft removed
4485 it. The client must resolve the nickname from the NAMES command
4486 reply received when it joined the channel.
4488 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4490 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Fixed some errors in protocol specification drafts.
4494 * Created lib/silccore/silcnotify.c to implement Notify Payload
4495 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4496 generic payloads described by protocol specifications. The file
4497 includes implementations for ID Payload and Argument Payload.
4499 * Changed Command Payload implementation to use the new Argument
4500 Payload. Changed command_xxxx_payload to command_payload_xxxx
4501 to comply with SILC coding conventions.
4503 * Added suppport for Argument Payload handling in Notify Payload
4504 implementation as protocol requires it. Added the new support
4505 into server and client lib as well.
4507 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Added support for multiple nicknames on same channel. [n] is
4510 added locally to the nickname if there are more than one same
4511 nicknames on the channel.
4513 * Server now sends all nicknames that matched WHOIS request.
4514 Client also shows the list received from server.
4516 * Added TOPIC command to client side. User can now set and show
4517 current topic on channel.
4519 * Added MOTD command to client and server. Also, server sends the
4520 motd when client connects to the server.
4522 * Changed version strings to comply ISO 8601.
4524 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Fixed protocol error handling in client library. It should now
4527 cope even if the SKE fails for some reason.
4529 * Made new protocol specification drafts for submitting to IETF.
4531 * Implemented TOPIC command to server in silcd/command.c.
4533 * Added two new notify types into lib/silccore/silcnotify.h:
4534 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4535 notify nickname change and topic setting/change on a channel.
4537 * API change of command_reply operation in client library. The
4538 application gets now the status type received from server as well.
4540 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4544 * Cras fixed and optimized the packet handling even further and
4545 it should work now. Minor change to the prototype of function
4546 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4548 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added new function into lib/silcutil/silcschedule.[ch]:
4551 silc_schedule_with_fd to select() a specified fd. The function
4552 returns after timeout expires or data arrives or goes. The
4553 function is used by packet routines to wait that all data is
4554 received from network.
4556 * Fixed data reading from network in lib/silccore/silcpacket.c.
4557 The code now assures that all data is read from the fd and then
4558 continues packet processing. This was a bug fix since the code
4559 used to drop some data in some circumstances.
4561 * Added new function into lib/silcclient/client.[ch]:
4562 silc_client_start_key_exchange to start key exchange after
4563 connection has been established to server. The code internally
4564 now uses this funtion but its main purpose was to provide it
4565 for applications that perform their own connecting. After
4566 application has created a connection it merely calls this
4567 function to start the key exchange between client and server.
4568 The library takes care of everything else after that.
4570 Updated also lib/silcclient/README to explain the usage of
4573 * Do not send to application information that connection has
4574 been established. Application gets notified it by connect
4577 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Applied cras's patch to add silc_schedule_one function. The
4580 function runs scheduler once and returns.
4582 * Fixed the scheduler after cras messed it up. The timeout
4583 handling works now as it's supposed to work.
4585 * Added into lib/silccore/ silcnotify.h to include notify
4586 message types support. Changed silc_server_send_notify*
4587 functions, in server.[ch], to support those new notify types.
4588 Added the support for the notify types into client library,
4589 as well. Added new notify client operation into ops.h in
4592 * Changed silc_server_packet_send_to_channel to send normal
4593 packets instead of just channel message packets. The function
4594 is now used to send the notify packets to channels. It is not
4595 used to send channel message packets anymore, as server never
4598 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4599 va_arg()s as it seems to require it nowadays. I guess, if SILC
4600 is compiled with older va_arg() the new code should work anyway.
4602 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Splitted core library. Core library (lib/silccore) includes
4605 now only SILC protocol specific core (and common) components.
4606 Created new utility library (lib/silcutil) that includes more
4607 generic purpose stuff. The stuff for util library was taken
4608 from the old core library. This was minor and easy split.
4610 * Created SILC Client Library (lib/silcclient) that includes
4611 implementation of the SILC client without user interface. This
4612 was major move from silc/ directory. The code has been changed
4613 so that it is transparent towards the user interface. The
4614 silc/ directory includes now the same user interface as before
4615 and it uses the new client library. Read lib/silcclient/README.
4616 Basicly, the client library performs everything else related
4617 to SILC except user interface handling. Also, configuration
4618 files are considered to be part of user interface and library
4619 does not handle them.
4621 This change also changed a lot of structures, function naming etc.
4622 Most important change was that SilcClientWindow object was
4623 renamed to SilcClientConnection in the client library. Created
4624 also new file lib/silcclient/ops.h. Also added new files
4625 silc/local_command.[ch] and silc/client_ops.[ch].
4627 All these changes were made to make it easier for user interface
4628 designers to create what ever user interface for the SILC client
4631 It is also expected that the server will be moved to lib
4632 directory as well and SILC Server Library will be created;
4633 sometimes in the future.
4635 * Removed Local commands from lib/silccore/silccommand.h as
4636 they are application specific and new client library does not
4637 handle any of those anymore.
4639 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4640 old client implementation in silc/.
4642 * Added support for callback functions in SILC_LOG_* macros.
4643 Application can now set its own callbacks that will be called
4644 instead of using the default functions that will always print
4645 the debug messages to stderr (or stdout). Also, debugging can
4646 now be disabled by setting silc_debug to FALSE and re-enabled by
4647 setting it to TRUE. Note, that logging will still work even
4648 if debugging is disabled.
4650 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4651 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4652 silc_log_reset_debug_callbacks.
4654 * To enable debugging in silc client one must give now -d
4655 option on command line.
4657 * Changed silc_schedule_init to automatically allocate task queues
4658 if they are not allocated before calling it.
4660 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Added GMP 3.1 into math library.
4664 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4667 a channel in SILC network. The packet is used by servers and
4668 routers to notify other routers that user has left a channel.
4669 This little feature was missing until now. Added the feature
4670 to protocol specification as well.
4672 Added functions: silc_server_send_remove_channel_user and
4673 silc_server_remove_channel_user into server.[ch].
4675 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4676 lib/silccore/silcpacket.h. However, they are not implemented
4679 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Fixed joining to a channel and sending channel messages
4682 between server and router. The channel message sending should
4683 now work inside a cell.
4685 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Fixed the private message sending between server and router.
4688 The private message sending should now work inside a cell.
4690 * Added silc_server_replace_id into server.[ch] to replace
4691 existing ID in the SILC network.
4693 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4694 and silc_idlist_replace_server_id into idlist.[ch] in server.
4696 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Fixed the server to server connections. Server can again now
4699 connect to router. Router to router connections probably does
4702 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Added dynamic protocol registering support. Now protocols can
4705 registered and unregistered on the fly. Patch by cras.
4707 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added lib/contrib directory to hold routines that some platforms
4710 don't have but are needed by SILC.
4712 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4713 into lin/contrib to provide getopt() and getopt_long() for
4714 those who don't have it.
4716 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Added AWAY command to client. When away message is set and
4719 client receives a private message packet the client automatically
4720 replies to the sender with the away message.
4722 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4723 bug seemed to be the cause of recent problems when compiling
4726 * Added version detection support to SKE protocol specification
4727 and added the new changes to the SKE implementation as well.
4728 There were other minor changes in the SKE protocol as well.
4730 Many changes in lib/silcske/silcske.[ch] and in
4731 lib/silcske/payload.[ch].
4733 * Added ^U functionality, clear input line. Patch from cras.
4735 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Mainly small bugfixes on core library. Fixed some debugging
4738 logging and buffer overflow in silclog.c.
4740 * Updated config.sub and config.guess on the distribution tree.
4742 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added command lagging support in server. Client may execute
4745 commands now only once in two seconds.
4747 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Optimized packet reception. MAC computation and checking is now
4750 also more optimized. A lot previously duplicated code is now
4751 used as generic by both client and server.
4753 * Fixed key pair generation in clientutil.c
4755 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added into lib/silccore/silcbufutil.[ch] new function;
4758 silc_buffer_realloc.
4760 * Moved generic packet sending/encryption functions to
4761 lib/silccore/silcpacket.[ch] from client and server. Some
4762 rewriting of the functions.
4764 * Moved all generic packet reception/decryption functions to
4765 lib/silccore/silcpacket.[ch] from client and server. The
4766 packet processing is now much cleaner in both client and server.
4767 These were major changes in both client and server.
4769 * Created many common functions in server to do packet sending.
4770 Previously code were duplicated a lot, this has been removed
4773 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Rewrote major parts of the ID cache system. Don't know
4776 whether it is better now or not but at least the API is more
4779 * Major rewrite on ID cache stuff on client because of the ID
4780 cache API changes. Added idlist.c to client.
4782 * Also major rewrite on ID cache stuff on server as well.
4783 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4784 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4785 in hand, instead they are all put into the ID cache system now.
4786 All server_idlist_* routines uses ID cache now instead of
4787 traversing its own lists (those lists does not exist anymore).
4788 SilcIDList though still exists. Also, SilcXXXEntry's are
4791 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * Finally made the SKE implementation compliant to the protocol
4794 specification. All mp integers are now binary encoded as
4795 opposed being HEX encoded.
4797 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4800 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4801 functions: silc_[encode/decode]_pem. Also added function
4802 silc_encode_pem_file to PEM encode with newlines ('\n') for
4805 * SILC public keys are now encoded either PEM or binary. Same
4806 option is for private keys as well. By default private keys
4807 are binary encoded and public keys PEM encoded. Silly HEX
4808 encoding were removed.
4810 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4811 function to create fingerprints.
4813 * Fixed a bug in SHA1; does not change the original data anymore.
4815 * Partly implemented INFO command on client and server side.
4816 Fixed CLEAR command. Changes to SERVER command; show current
4817 server(s) when giving command without arguments. Added
4818 VERSION command to client.
4820 * Added check to server that unregistered connections cannot
4821 execute commands (unless it is specificly allowed).
4823 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Fixed screen refresh.
4827 * Fixed channel joining bug from client. On some circumstances
4828 client tried to join to a channel it had already joined.
4830 * Added public key verification process into client's protocol.c.
4831 The client now verifies the public key from user and saves
4832 it into ~./silc/serverkeys/ directory.
4834 Added into: clientutil.[ch]: silc_client_verify_server_key.
4836 * Changed SKE protocol's silc_ske_initiator_finish function
4837 to accept callback function that verifies the received public
4838 key. Removed old silc_ske_verify_public_key function.
4840 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4843 silc_pkcs_private_key[_data]_set.
4845 * Made the password and public authentication more cleaner in
4846 server's protocol.c.
4848 * Removed historic and obsolete protocol `channel_auth' from
4849 both client and server.
4851 * Removed wrong way of sending command status messages from
4852 server to client in server's command.c. The old way violated
4853 protocol specification.
4855 Changes to silccore/silccommand.[ch]: removed
4856 silc_command_encode_status_payload -> not needed anymore,
4857 changed silc_command_encode_payload_va to accept extra
4858 argument on variable argument list. The argument type must
4859 now be provided to the function. Also, added new function:
4860 silc_command_encode_reply_payload_va which is same as
4861 normal command_encode_payload_va except command status type
4862 is provided as extra argument.
4864 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Added ~./silc directory handling. The directory includes the
4867 public and private keys for the client.
4869 Added silc_client_check_silc_dir, silc_client_create_identifier
4870 and silc_client_load_keys.
4872 * Implemented SILC protocol compliant public key. Added public
4873 and private key saving to and loading from files.
4875 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4876 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4877 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4878 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4879 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4881 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4882 silc_pkcs_load_[public/private]_key.
4884 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added silc_server_get_route (route.[ch]) to get connection
4887 data for the fastest route for given ID.
4889 * Implemented INVITE command on client and server. The command
4890 were re-defined in the SILC Protocol Specification and the
4891 implementation now complies with the specification.
4893 * Implemented PING command on client and server.
4895 * Implemented NAMES command on client and server. The server side
4896 supports currently only normal server not router server yet.
4897 Some changes to NAMES definition in SILC protocol specification.
4899 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Implemented LEAVE command on client and server.
4903 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4904 again. This change was made to the protocol as well. Server
4905 should not violate the protocol specification anymore.
4907 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4910 was tested. SOCKS4 was not but should work anyway.
