1 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the silc_id_create_client_id to be collision
4 resistant. It is now assured that there cannot be created
5 two same client ID's. I suspect that some weird bugs in
6 the server were actually caused by duplicate Client IDs.
7 Affected file silcd/serverid.[ch]. A router receiving
8 new ID now also assures and informs the sending server
9 if the ID caused collision.
11 * Changed the silc_id_create_channel_id to also assure that
12 there are no collisions.
14 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Statement about ignoring the Mutual Authentication flag when
17 performing rekey with PFS was a bit misleading. It is ignored
18 if it was set in the initial negotiation, it cannot be even
19 set in the rekey. Fixed in the ke-auth draft. Started the
20 new versions of the protocol drafts in the doc/.
22 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
24 * Fixed a bug in silc_client_command_identify_save when saving
25 new channel information. The channel name was no duplicated
26 and caused crash on exit. Affected file is
27 lib/silcclient/command_reply.c.
29 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
31 * Fixed the getkey command handling in the server. Send just
32 empty OK reply to the sender if the key could not be fetched
33 (but everything else was ok, like the key just was not available).
34 Changed the public key parameter to optional in the protocol
35 specs so that empty OK reply can be sent. Affected file
38 Added a message to Irssi SILC client to tell to user if the
39 server did not return a public key.
41 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Fixed a channel key regeneration bug. It registered new
44 timeout tasks exponentially until all system resources were
45 used. Affected file silcd/server.c.
47 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
49 * Added the SILC Document generator to the scripts/silcdoc.
50 It can be used to generate the Toolkit Reference Manual out
51 of the source tree. Internally it will also use the RoboDoc
52 generator now imported in util/robodoc.
54 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Added couple of return's in rekey protocol if error orccurred
57 during the protocol. The execution must be terminated.
58 Affected file silcd/protocol.c. Also, terminate the protocol
61 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
63 * The client's Client ID was created initally from the wrong
64 nickname (it could have been in format nick@host) in the
65 silc_server_new_client. Affected file silcd/packet_receive.c
67 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
69 * Added some SILC_LOG_ERROR's to various error conditions
70 if client could not be added to ID cache. Affected files
71 silcd/packet_receive.c and silcd/server.c.
73 * When client's sock->user_data is freed, NULL also the
74 client->router and client->connection pointers. Added check
75 for these pointers being NULL to various places around the
76 code. Affected file silcd/server.c.
78 * Added client->data.registered == TRUE checks to various
79 places around the code to assure that unregistered client's
80 are not handled when it is not allowed. Affected file
83 * Added `bool registered' fields to all
84 silc_idlist_[server|client]_get_* routines to indicate whether
85 the fetched client needs to be registered or not. Affected
86 file silcd/idlist.[ch].
88 * Add your own entry as registered to the ID cache in the
89 server. Affected file server.c.
91 * Fixed a bug in silc_server_new_server. The SilcServer was
92 set as the new server's context instead of SilcServerEntry.
93 This naturally caused some weird bugs.
95 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Do not delete the channel rekey task when adding it
98 for in silc_server_create_channel_key.
100 * Changed the silc_server_create_channel_key to return
101 TRUE or FALSE to indicate the success of the channel key
104 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
106 * Fixed MSVC++ project files and added missing files to
107 Makefiles under win32/.
109 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
111 * Do not add TCP_NODELAY flag if the operating system
112 does not have it defined. Affected files are
113 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
115 * Fixed buffer overflow from Irssi SILC Client. Affected
116 file irssi/src/fe-common/core/themes.c.
118 * Fixed double free in client library in the file
119 lib/silcclient/client.c when disconnecting from server.
121 * Applied double free patch from cras to Irssi SILC client.
122 Affected files irssi/src/core/[modules/expandos].c
124 * Fixed the disconnection handling to Irssi SILC Client.
125 The application must call silc_client_close_connection
126 in ops->connect client operation in case of failure of
127 the connection. Affected file is
128 irssi/src/silc/core/client_ops.c.
130 * Do not set sock->protocol to NULL in the function
131 silc_client_close_connection after executing the protocol's
132 final callback since the sock might not be valid anymore.
133 Affected file lib/silcclient/client.c.
135 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Do not enable SILC_THREADS if the linking with libpthread
138 did not happen. Affected file configure.in.pre.
140 * Added notion to protocol specification that server must
141 verify the sent authentication payload with CMODE when
142 setting the channel founder key. Implemented it to the
143 server. Affected file silcd/command.c.
145 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
147 * Added _EXTRA_DIST SILC distribution variable to the
148 distributions file. It is used to conditionally add extra
149 files or directories to the specific distribution. Affected
150 files ./prepare, Makefile.am.pre and distributions.
152 Removed the `_' from the start of the distribution names.
155 * Added README.WIN32 for instructions to compile the Toolkit
158 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
160 * Fixed a double free in disconnection in the server. Affected
161 file is silcd/server.c.
163 * Fixed the lib/silcske/groups.c to work now also with GMP
164 MP library. The string conversion did not work when using
165 specific base and the base is indicated in the string as well.
167 * Created win32/ directory which now includes MSVC++ specific
168 stuff so that toolkit (DLLs) may be compiled with MSVC++.
169 It will appear only in the toolkit distribution
171 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
173 * Changed the key material distribution function in case when
174 the hash output is too short. The data is now concatenated
175 a bit differently than it used to. Made the change to the
176 SKE protocol specification.
178 * Added better GMP detection to configure.in.pre. A patch
181 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
183 * Fixed a minor bug in SKE that might cause some problem on
184 some platforms. Affected file lib/silcske/silcske.c.
186 * Added the cookie checking for initiator in the SKE. It checks
187 that the responder returns the sent cookie unmodified. The
188 affected file is lib/silcske/silcske.c. Added new SKE
189 error type INVALID_COOKIE that can be sent during the
190 negotiation. Fixed some memory leaks as well.
192 * Added the "invalid cookie" error message to Irssi SILC client's
195 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
197 * Added `task_max' field to the SilcClientParams to indicate
198 the maximum tasks the scheduler can handle. If set to zero,
199 default values are used. Affected file lib/silcclient/silcapi.h.
201 * Fixed memory leaks in silc_client_close_connection. Affected
202 file lib/silcclient/client.c.
204 * Added silc_client_del_client_entry to client library to free
205 all memory of given client entry. Affected file is
206 lib/silcclient/idlist.[ch].
208 * Added new functions silc_client_del_channel and
209 silc_client_del_server to delete channel and server entries.
210 Affected file lib/silcclient/[silcapi.h/idlist.c].
212 * Removed silc_client_del_client_by_id from silcapi.h.
214 * Fixed the INFO command to return the server's own info
215 correctly when querying by Server ID. Affected file is
218 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
220 * Removed the non-blocking settings in WIN32 code in the
221 silc_sock_[read/write] and added SleepEx instead. Affected
222 file lib/silcutil/win32/silcwin32sockconn.c. The availability
223 of input data is now checked with FIONREAD and ioctlsocket.
225 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
227 * Call silc_schedule_task_del_by_context in the
228 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
229 Affected file lib/silccore/silcprotocol.c.
231 * Call silc_protocol_cancel for active protocols in the
232 silc_server_close_connection if the funtion
233 silc_server_free_sock_user_data has not been called.
234 Affected file silcd/server.c.
236 * Generic tasks cannot be deleted using the del_by_fd
237 task deleting function since generic tasks does not match
238 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
240 * Added a notion to SILCOPER help file that the SILCOPER works
241 only on router server, not on normal server.
243 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
245 * Added for WIN32 support for the new scheduler as well.
246 Affected file lib/silcutil/win32/silcwin32schedule.c.
248 * Fixed the SHA1 implementation to work on various platforms.
250 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
252 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
253 API. It is part of the scheduler now. Everything else is
254 as previously but some functions has changed their names.
255 Checkout the lib/silcutil/silcschedule.h for the interface.
256 Updated all applications to use the new interface. Affected
257 files are lib/silcutil/silcschedule.[ch].
259 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
261 * Found a bug in the SKE implementation. The HASH value,
262 specified by the protocol, was not computed correctly. The
263 public key of the responder was not added to the computation
264 even though it is mandatory. Affected file lib/silcske/silcske.c.
265 This unfortunately causes incompatibilities with older
268 * Added WIN32 specific network init and uninit functions:
269 silc_net_win32_init and silc_net_win32_uninit to init and uninit
270 the Winsock2. Affected file lib/silcutil/silcnet.h and
271 lib/silcutil/win32/silcwin32net.c.
273 * Set the socket always to nonblocking mode on WIN32 after
274 reading data or writing data. Affected file is
275 lib/silcutil/win32/silcwin32sockconn.c.
277 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
279 * Fixed various compilation problems under WIN32. Affected
280 files lib/silcutil/win32/silcwin32thread.c and
281 lib/silcutil/win32/silcwin32schedule.c.
283 * Removed all _internal.h #includes from public header
284 files. Internal headers must never be included from
287 Removed also the lib/silcske/payload_internal.h file.
289 * All include files that may be needed (public and some others
290 included by the public headers) by application developers are
291 now copied to the ./includes directory. It does not copy any
292 internal headers. Affected file Makefile.defines.pre and all
293 Makefile.am's under lib/ and subdirs.
295 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
297 * Do not change the ~/.silc directory's permissions automatically.
298 Affected file irssi/src/silc/core/clientutil.c.
300 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
302 * Do not cancel the protocol in silc_server_close_connection
303 it might cause recursion. Now cancelled in the function
304 silc_server_free_sock_user_data. Affected file silcd/server.c.
306 * Fixed the silc_server_remove_clients_by_server to regenerate
307 the channel keys correctly finally. Added also new function
308 silc_server_remove_clients_channels to actually do it.
309 Affected file silcd/server.c.
311 * Fixed the silc_server_new_channel to not crash by giving
312 wrong router to the new channel. Affected file is
313 silcd/packet_receive.c.
315 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
317 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
318 which is given as argument to the silc_client_alloc now.
319 It can be used to configure the client and set various parameters
320 that affect the function of the client.
322 * The USERS command in server did not check whether the channel
323 is private or secret. Affected file silcd/command.c.
325 * Added new argument to the USERS command in protocol specification.
326 The USERS command now can take the channel name as argument
327 as well. Added support for this in client and server and
328 updated the protocol specs.
330 * Completed the GETKEY command in client. It can be now used
331 to fetch also servers public key not only some clients.
332 Affected files lib/silcclient/command[_reply].c.
334 * Added silc_client_get_server to return server entry by the
335 server name. Affected files lib/silcclient/silcapi.h and
338 * Redefined the IDENTIFY command in protocol specification to be
339 more generic. It now can be used to query information about
340 any entity in the SILC Network, including clients, servers and
341 channels. The query may be based either the entity's name
342 or the ID. Added support for this in both client and server.
344 Affected files silcd/command.c and lib/silcclient/command.c
347 * Optimized the WHOIS and WHOWAS commands in the server. Removed
348 the _from_client and _from_server functions. Affected file
351 * Added silc_client_get_channel_by_id_resolve to the file
352 lib/silcclient/silcapi.h to resolve channel information by
353 its ID. Added also silc_client_get_channel_by_id that
354 does not resolve it from the server.
356 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Added SilcServerEntry context into the client library
359 to represent one server. The INFO command now allocates
360 these to save the resolved server info. For now on the
361 client library will also keep information about servers,
362 connected and resolved with INFO.
364 The INFO command now allocates the SilcServerEntry context
365 and saves the server info there. The COMMAND_REPLY in
366 the INFO now returns the parameters to application in
367 same order as defined in the protocol specification.
369 The entries are cached in the client->server_cache.
371 * The INFO command is now issued after received the Client ID
372 from the server. Affected file lib/silcclient/client.c.
374 * The CMODE_CHANGE notify may now return also an SilcServerEntry
375 to the application as the mode changer might be server.
376 It is guaranteed that NULL is not returned anymore to the
377 application. Affected file lib/silcclient/client_notify.c.
379 The ID Type is now also passed to the application so that
380 it can check whether the returned entry is SilcClientEntry
383 Added new function silc_client_get_server_by_id to return
384 the server entry by ID. Affected files are the
385 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
387 * Do not create the channel in the Irssi SILC Client when issuing
388 the JOIN command but when received the sucessful JOIN command
389 reply. Otherwise the channel might get created even though we
390 could not join it. The Affected file is
391 irssi/src/silc/core/[silc-channels.c/client_ops.c].
393 * Fixed a channel joining bug in router. The router must also
394 check the channel modes, invite and ban lists etc. when serving
395 the JOIN command sent by normal server. Affected file is
396 silcd/command.c. The router now resolves the client's
397 information from the server who sent the JOIN command if it
398 does not know it, and processes the JOIN command only after
401 * Changed the SilcCommandCb to take new argument; void *context2.
402 Affected file lib/silccore/silccommand.h
404 The second argument in the command callbacks in the server now
405 includes the SilcServerCommandReplyContext if the command was
406 called as pending command callback from the command reply.
407 Otherwise it is NULL. When called as pending the status of the
408 command reply will be checked and if it was erronous the
409 error will be sent to the original sender of the command.
410 This way the client always receives the error messages even
411 though the server was actually the one who received the error
412 when it resent the command to router, for example. Affected
413 files silcd/command[_reply].[ch].
415 * Fixed sending WHOWAS command's error message to client if
416 the requested client could not be found. It was missing.
419 * Changed the CMODE and CUMODE commands reply arguments in the
420 protocol specification. The Channel ID is now sent in both
421 of the commands to identify the channel. Implemented this
422 new feature to the client and server. Affected files
423 lib/silcclient/command_reply.c and silcd/command.c.
425 * Made better checks for invite and ban lists in the JOIN
426 command in server. Affected file silcd/command.c.
428 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
430 * The server now performs the incoming host IP/DNS lookup
431 using the silc_socket_host_lookup and thus does not block
432 the server anymore. Affected file silcd/server.c.
434 * Completed the multi-thread support for SILC Scheduler in
435 the lib/silcutil/silcschedule.c.
437 * Fixed the configure.in.pre to detect the pthread correctly
440 * Fixed a deadlock in silc_task_queue_wakeup in the file
441 lib/silcutil/silctask.c.
443 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Added new function silc_schedule_wakeup that is used in
446 multi-threaded environment to wakeup the main thread's
447 schduler. It needs to be used when a thread adds a new task
448 or removes a task from task queues. After waking up, the
449 scheduler will detect the task queue changes. If threads
450 support is not compiled in this function has no effect.
451 Implemented the wakeup mechanism to both Unix and WIN32
452 systems. Affected files are lib/silcutil/silcschedule.[ch],
453 lib/silcutil/unix/silcunixschedule.c and the
454 lib/silcutil/win32/silcwin32schedule.c.
456 * Added new function silc_task_queue_wakeup to wakeup the
457 scheduler by the specified task queue. Affected file
458 lib/silcutil/silctask.[ch].
460 * The silc_socket_host_lookup_start now wakes up the scheduler
461 after adding the timeout task. Affected file is
462 lib/silcutil/silcsockconn.c.
464 * The silc_socket_host_lookup is synchronous now if the threads
465 support is not compiled in. However, the callback is still
466 called asyncronously through the scheduler, anyway. Affected
467 file lib/silcutil/silcsockconn.c.
469 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
471 * Added new function silc_socket_host_lookup to perform
472 asynchronous IP and FQDN lookups for the socket connection.
473 Affected files lib/silcutil/silcsockconn.[ch].
475 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
477 * Added SILC_MUTEX_DEFINE to define the mutex on environments
478 that may or may not compile the mutex support in.
480 Changed the silc_mutex_alloc interface. It allocates the
481 mutex now to the sent pointer and returns TRUE or FALSE.
483 Affected file lib/silcutil/silcmutex.h.
485 * Wrote the SILC Task Queue interface to support multi-threads.
486 Affected file lib/silcutil/silctask.[ch].
488 * Wrote the SILC Scheduler to support multi-threads. Affected
489 file lib/silcutil/silcschedule.c.
491 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Implemented the SILC Mutex API and SILC Thread API for WIN32
494 in lib/silcutil/win32/.
496 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
498 * Defined SILC Mutex API and SILC Thread API and implemented
499 them for Unix. Affected files are
500 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
501 lib/silcutil/unix/silcunixmutex.c and
502 lib/silcutil/unix/silcunixthread.c.
504 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
506 * Fixed the silc_server_remove_clients_by_server's channel
507 key re-generation. The hash table handling was incorrect
508 and would not work with many channels. Affected file is
511 * Fixed some memory leaks around the server code.
513 * Rewrote the silc_server_get_users_on_channel to support IPv6
514 based Client ID's. Affected file silcd/server.c.
516 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
517 specification. However, a separate document must be written
518 to define the detailed signing procedure and the payload
519 associated with the flag. Defined the flag to the
520 lib/silccore/silcchannel.h as well.
522 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
524 * Changed the dynamic tables to static size tables in the
525 lib/silccrypt/silchmac.c.
527 * Removed GCC dependencies from the code. A patch by cras.
529 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
531 * Do not show the error "Error receiving packet bla bla"
532 in server if it really was not an error (-2 means that reading
533 is pending). Affected file silcd/server.c.
535 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
537 * Fixed a possible crash in silc_server_remove_clients_by_server
538 in silcd/server.c. Fixed there also some memory leaks.
540 * Fixed the silc_idlist_replace_client_id. It could replace
541 wrong key in the hash table. Affected file silcd/idlist.c.
543 * Do not check whether there are global users on the channel
544 if the channel->global_users is FALSE. Affected functions
545 silc_server_remove_from_one_channel and
546 silc_server_remove_from_channels in silcd/server.c. Also,
547 do not check if the removed client is local as we can be
548 sure that global client was not removed from the channel
549 and checking for global users is not needed.
551 * The silc_server_remove_clients_by_server now re-generates
552 the channel keys correctly for those channels that had
553 clients removed from them. Affected file silcd/server.c.
555 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Found the reason of random crashes in the server. We weren't
558 ignoring the SIGPIPE signal (which can be sent in write())
559 and it crashed the server. Affected file silcd/silcd.c.
561 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
563 * Assure that sock->user_data is not NULL in the function
564 silc_server_packet_send in silcd/packet_send.c.
566 * Disconnect the remote connection if it could not be added
567 to any ID lists in the server. The affected file is
570 * Check in silc_server_packet_send[_real/dest] that the
571 socket is not disconnecting and ignore the data if it is.
572 Affected file silcd/packet_send.c.
574 * Define inline to __inline on native WIN32 compilation.
575 Affected file includes/silcwin32.h.
577 * Added some explicit type casts for inline code since MSVC
578 require them. Affected files lib/silcutil/silcbuffer.h,
579 lib/trq/silcdlist.h and lib/trq/silclist.h.
581 * Print warning in log files from now on if the packet
582 decryption fails. Affected file silcd/server.c.
584 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Changed the `say' client operation's interface to accept
587 new `type' argument to indicate the type of the message sent
588 by the library. The application may filter the library's
589 messages according the type. The affected file is the
590 lib/silcclient/silcapi.h.
592 * Added two new functions to lib/silcclient/silcapi.h:
593 silc_client_del_client and silc_client_del_client_by_id.
594 Affected file lib/silcclient/idlist.c.
596 * Moved the clientincludes.h from includes/ to silc/ and
597 serverincludes.h from includes/ to silcd/.
599 * The modes for the CMODE and CUMODE are now passed as
600 uint32 for application with COMMAND_REPLY. The affected
601 file is lib/silcclient/command_reply.c.
603 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
605 * /WHOIS without arguments shows client's own information.
606 Affected file lib/silcclient/command.c.
608 * Changed PING to not accept any arguments. The specs
609 says that client can ping only the connected server so
610 requiring an argument is not needed. Affected file is
611 lib/silcclient/command.c.
613 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
615 * Fixed a fatal bug in private message sending and reception
616 encryption and decryption when using private message keys.
617 The implementation was incorrect and did not follow the
618 specification. It causd that some of the message were
619 lost since it did not use the sending and receiving keys
620 as the protocol suggests. This has been fixed and will cause
621 incompatibilities with older clients when sending private
622 message encrypted with private message keys. Affected files
623 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
624 and various other in Irssi SILC Client.
626 Added `responder' boolean argument to the functions
627 silc_client_add_private_message_key[_ske] to indicate when
628 the key is added as responder or initiator of the key
631 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
633 * Removed the silc_ske_check_version function and created
634 a SilcSKECheckVersion callback. Added also a function
635 silc_ske_set_callbacks that is now used to set all SKE
636 callbacks. The callback functions are not given to
637 the SKE functions anymore, but this function is used to
640 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
642 * Added `silc_version' argument to the silc_client_alloc
643 to define the version of the application for the library.
644 The library will use the version string to compare it
645 against the remote host's (usually a server) version
646 string. Affected file lib/silcclient/silcapi.h
648 * Added the KE protocol context to Key Agreement context
649 in client library so that we can abort the SKE if it
650 is in process when we get timeout. Affected file is
651 lib/silcclient/client_keyagr.c.
653 * Do not resolve the client ID forever if it returns in the
654 first time that such client does not exist. This was done
655 for example with private message. Affected file is
656 lib/silcclient/client_prvmsg.c.
658 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Do not add regex.h for WIN32. The affected file
661 includes/silcincludes.h.
663 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
664 not work yet 100%. It generates the DLL's automatically
665 when compiling with --with-win32 under cygwin.
667 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
669 * lib/contrib/regex.c is not compiled on WIN32.
671 * Added silc_net_get_socket_opt function to the
672 lib/silcutil/silcnet.h.
674 * Added includes/silcwin32.h for WIN32 specific includes
677 * Do not use ptime structure or any of the posix process
678 functions on WIN32 in lib/silccrypt/silrng.c.
680 * Added silc_gettimeofday to provide generic function
681 for struct timeval on all platforms. Added the function
682 to lib/silcutil/silcutil.h.
684 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Moved the lib/silccore/silcsockconn.[ch] to the utility
687 library as they clearly belong there. As a plus side we
688 can make the actual socket connection routines platform
691 Added also new generic function silc_socket_read and
692 silc_socket_write (that used to be silc_packet_[read/write].
693 The implementation of these are platform specific.
695 * Added WIN32 specific routines of silc_socket_[read/write]
696 to lib/silcutil/win32/silcwin32sockconn.c.
698 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Added preliminary support for native WIN32 compilation under
701 cygwin (using the -mno-cygwin option for GCC) to the
702 ./configure.in.pre. The --with-win32 now prepares the
703 compilation for native WIN32.
705 * Rewrote the SILC Scheduler interface in the file
706 lib/silcutil/silcschedule.h. The scheduler is now context
707 based and does not have anymore any global static scheduler.
708 Moved the Unix scheduler to the lib/silcutil/unix/ directory
709 and created lib/silcutil/win32 directory for WIN32 based
712 * Added Unix specific network routines to the
713 lib/silcutil/unix/silcunixnet.c and the old
714 lib/silcutil/silcnet.c includes now only generic routines.
716 Added WIN32 specific network routines to the
717 lib/silcutil/win32/silcwin32net.c.
719 * Added Unix specific utility functions from the
720 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
722 * Added WIN32 SILC Scheduler to the file
723 lib/silcutil/win32/silcwin32schedule.c. The code is of course
726 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
728 * Do not handle JOIN notify in the server if the target client
729 is not registered (idata->registered == FALSE). The affected
730 file is silcd/packet_receive.c.
732 * Update the nickrec->founder in event_cumode in the Irssi SILC
733 client. Affected file irssi/src/silc/core/silc-channels.c.
735 * Fixed the CUMODE_CHANGE notify handling in the server when
736 server and router are announcing their clients on channels.
737 Now the mode changes are saved and notified correctly. The
738 affected file is /silcd/packet_receive.c.
740 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
741 They really did not replace the cache entry in the ID Cache.
742 Now they do that. Affected file silcd/idlist.c.
744 * Fixed the KICK notify handling in the Irssi SILC client to
745 update the channel records so that the kicked client does not
746 appear to be on the channel. The affected file is
747 irssi/src/silc/core/silc-channels.c.
749 * Always update the conn->current_channel when executing command
750 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
752 * Fixed the KILL notify handling in Irssi SILC client to remove
753 the killed client on all channels.
755 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Fixed the silc_parse_command_line to remove extra spaces
758 from the start and end of the arguments. Affected file is
759 lib/silcutil/silcutil.c.
761 * Cancel and free any active protocol in the function
762 silc_server_close_connection. Affected file silcd/server.c.
764 * Cancel and free any active protocol in the function
765 silc_client_close_connction. Affected file is
766 lib/silcclient/client.c.
768 * Do not execute the KILL command for clients that are in
769 history (ie. they are not in the network). Affected file is
772 * Fixed KILL notify handling, client does not crash anymore.
773 Affected file irssi/src/silc/core/silc-channels.c.
775 * Reduced the default packet buffer size from 2048 to 1024 in
776 lib/silccore/silcpacket.c.
778 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
779 counter to the SKE context that is incresed when the SKE library
780 performs async operation outside the library. If the outside
781 process frees the SKE context and FREED status will be set
782 and the library will detect after the sync operation that the
783 libary is freed. The affected files are
784 lib/silcske/silcske[_status].[ch].
786 * Resolve the client entry information in the function
787 silc_client_channel_message to assure that NULL pointer is not
788 passed as client entry to the application. */
790 * Fixed the task timeout calculation to assure that there is
791 never negative timeouts. The affected file is
792 lib/silcutil/silcschedule.c.
794 * Fixed the channel user mode notification sending in server.
795 It was sent point-to-point to the router (or to server by router)
796 but it needs to be destined to a channel. The routines now
797 supports sending the channel user mode notifys to the channels
798 when announcing clients and channels. Affected files are
799 silcd/server.c and silcd/packet_receive.c.
801 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
802 It did not actually replace the old channel entry in the cache.
803 Affected file lib/silcclient/client_notify.c.
805 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Fixed a possible crash in silc_packet_send_prepare. It now
808 assures always that there is enough space in the buffer and
809 at the tail area of the buffer (for MAC).
811 Fixed the inbound buffer reallocation in silc_packet_read.
812 It was old code and did not handle the reallocation correctly.
815 The affected file is lib/silccore/silcpacket.c.
817 * Fixed buffer overflow in silc_parse_nickname in the file
818 lib/silcutil/silcutil.c.
820 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * make install generates new server keys only if there is not
825 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
828 Added check that if the NOREPLY is set then we will not send
829 the away message. This avoids infinite loop of away messages
830 if both clients are away. The affected file is
831 lib/silcclient/client_prvmsg.c.
833 * Fixed client crash if /NICK was given without arguments.
834 Affected file lib/silcclient/command.c.
836 * Server does not send the invite list in INVITE command back
837 to the client if the list was not altered. Added this notion
838 to the protocol spec as well. Affected file silcd/command.c.
840 Fixed possible crash in INVITE command by checking the
841 value of silc_server_get_client_route command.
843 * Fixed the INVITE notify type handling. The arguments are now
844 taken in correct order and client does not crash. The affected
845 file is irssi/src/silc/core/silc-channels.c.
847 Removed the "Inviting xxx to channel" message from the
848 client library away and let the application handle it.
849 Affected file lib/silcclient/command.c. Added that message
850 to Irssi SILC client's message formats.
852 * Fixed CMODE command crash in client. It now checks the
853 amount of arguments correctly and does not crash. The affected
854 file is lib/silcclient/command.c.
856 * Do not create new channel automatically in silc_channels_join
857 but check whether the channel by that name already exists.
858 Affected file irssi/silc/core/silc-channels.c.
860 * Do not send the SERVER_SIGNOFF to router if the disconnected
861 entity was the router. Affected file silcd/server.c.
863 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
864 SILC client as it was missing from there.
866 Added the handling of the KICK notify to the Irssi SILC client
867 as it was missing. Added "you have been kicked" message to
868 Irssi SILC client's message modules formats.
870 Added the handing of the KILL notify to the Irssi SILC client
871 as it was missing. Added the kill message module formats
874 The affected file is irssi/src/silc/core/silc-channels.c.
876 * The router did not save the channel mode the server announced.
877 Affected file silcd/packet_receive.c.
879 * Fixed a possible crash in INFO command in server. If the
880 server did not provide the server info it crashed. Affected
881 file silcd/command.c.
883 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Fixed the GETKEY command in the server to check also the
886 global list. Otherwise the GETKEY would not work correctly
887 in normal SILC server. Affected file silcd/command.c.
889 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * Fixed GETKEY crash, it crashed if the command did not succseed.
893 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
896 is now real and not just an macro interface to GMP.
898 Removed the entire GMP from the source tree and imported new
899 NSS MPI library instead. Reason for removing GMP is that it is
900 extremely large and compiles extremely slow. The NSS MPI
901 is only a few files and compiles in less than 10 seconds.
902 The speed is also about the same as GMP. The MPI is imported
905 If the system has GMP installed we will still use the GMP.
906 If it is not then the NSS MPI will be compiled.
908 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Merged a long nickname (127 characters long) crash bugfix from
911 Irssi CVS tree. Affected file irssi/src/core/misc.c.
913 * Merged a freed memory reference bugfix from Irssi CVS tree.
914 Affected file irssi/src/core/commands.c.
916 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
918 * Added the server's public key sving and verification to the
919 server when performing the SKE. This was missing and the
920 remote server's (or router's) public key was accepted without
921 checking whether we have it previously or trust it at all.
922 Affected file silcd/protocol.c.
924 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Check in the silc_server_timeout_remote if protocol is active
927 and make sure that the protocol's final callback is called so
928 that all memory if freed. Affected file silcd/server.c.
930 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * silc_server_whois_send_reply crashed the server if the nickname
933 was 127 characters long. Affected file silcd/command.c.
935 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Added sanity check to the silc_server_new_client. If the hostname
938 is provided inside username then check that the provided hostname
939 really is the same as the resolved one. If the hostname was not
940 resolved then check it from the public key. Affected file is
941 silcd/packet_receive.c.
943 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
944 if the server disconnected us and the connection is not valid
945 anymore. Affected file irssi/src/silc/core/silc-channels.c.
947 * Moved the silc_client_[chmode|chumode|chumode_char] away from
948 the library to the lib/silcutil/silcutil.[ch].
950 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Close log file after open. Affected file
953 lib/silcutil/silclog.c.
955 * Check whether sock == NULL in silc_client_send_packet and return
956 if it is. Affected file lib/silcclient/silcclient.c.
958 * Check rec->entry == NULL in the Irssi SILC Client before
959 sending the channel message. Affecte file is
960 irssi/src/silc/core/silc-servers.c.
962 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Merged a splitted window bugfix from Irssi CVS tree. The
965 affected file is irssi/src/fe-text/textbuffer-view.c.
967 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
968 It did not print nickname.
970 * Improved the distributions system a bit.
972 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
975 irssi/src/fe-text/gui-window.c.
977 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
978 to in-active server. The affected file is
979 irssi/src/silc/core/client_ops.c.
981 * Resolve the client in USERS command reply if the entry does
982 not have username resolved. The affected file is
983 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
984 command to WHOIS command to really resolve stuff. The USERS
985 is not used any more in any critical section so WHOIS can
986 be used even though it might be slower than IDENTIFY.
988 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
991 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Changed the protocol API a bit more consistent in the
994 lib/silccore/silcprotocol.[ch].
996 * Changed the following headers to ROBODoc format:
998 lib/silccore/silcpayload.h
999 lib/silccore/silcprotocol.h
1000 lib/silccore/silcsockconn.h
1002 All core library headers are now formatted.
1004 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Fixed a bug in Irssi SILC client; do not show that you are
1007 server/router operator if you really are not. Affected file is
1008 irssi/src/silc/core/client_ops.c.
1010 * Renamed silc_command_free_payload to silc_command_payload_free.
1011 Affected file lib/silccore/silccommand.h
1013 * Added silcmath.h to include the prototoypes of various routines
1014 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1017 * Changed the following headers to ROBODoc format:
1019 lib/silccore/silcchannel.h
1020 lib/silccore/silccommand.h
1021 lib/silccore/silcid.h
1022 lib/silccore/silcidcache.h
1023 lib/silccore/silcmode.h
1024 lib/silccore/silcnotify.h
1025 lib/silccore/silcpacket.h
1026 lib/silcmath/silcmath.h
1028 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1030 * Added checking to the server code not to start the server if
1031 ciphers and stuff are not configured properly. Affected files
1032 silcd/serverconfig.[h] and silcd/server.c.
1034 * Changed the layout of the header files of the public interfaces
1035 in the SILC libraries. The new layout supports ROBODoc
1036 documentation tool (and some others) so that it is easy to create
1037 a library reference manual. All the other headers and source
1038 code must still follow the CodingStyle document. Also source
1039 code must not include these ROBODoc stuffs, only the headers.
1040 Furthermore, all public interface headers must now be named
1041 by using `silc' prefix, example: silcapi.h, silccipher.h.
1042 Some files were renamed due to this. All the other headers
1043 must not be used as public interfaces. I will update the
1044 CodingStyle document later. Changed following headers, so far:
1046 lib/silcclient/silcapi.h
1047 lib/silccore/silcauth.h
1048 lib/silccore/silcprivate.h
1049 lib/silccrypt/silcdh.h
1051 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Removed silc_client_packet_send_flush from the client library
1056 as it is not needed. Affected file lib/silcclient/client.[ch].
1058 * Added printing of message of unresolved authentication method
1059 to the Irssi SILC client. Added it to the module formats.
1060 Removed the same message from the client library.
1062 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Added new distribution feature, DISTLABEL. Every distribution
1065 can define own preprocessor label that can be used in the
1066 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1067 file distributions, acconfig.h.pre and prepare.
1069 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1071 * Added Makefile.defines_int to include the actual definitions
1072 for Makefile.defines.in. Tested the new distribution system,
1073 created distributions and tested installation.
1075 * Added AWAY message printing to the Irssi SILC client. Added
1076 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1078 * Added SCONNECT command to call the SILC's CONNECT command.
1079 Cannot use CONNECT directly since Irssi uses that internally.
1080 Affected file irssi/src/silc/core/silc-servers.c.
1082 Added ACTION local command. It is same as ME command but takes
1083 the channel as mandatory argument.
1085 Rewrote some of the Irssi's help files to suite for SILC
1088 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Added Makefile.defines[.in] that should for now on be included
1091 in all Makefile.am file in the source tree. That file includes
1092 all common compilation definitions for SILC source tree.
1094 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Minor changes to the ./prepare script to change the package
1097 name according the distribution name to the configure.in.
1099 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Created new distribution system. Added file `distributions'
1102 that defines all the distributions that can be created out of
1103 the SILC source tree. The ./prepare script now reads that
1104 file to determine how to prepare the distributions. The
1105 first argument to the ./prepare is the name of the distribution
1106 and second is the version of the distribution. If given
1107 without arguments it creates the default (toolkit) distribution
1108 with the default version (defined in ./prepare).
1110 All Makefile.am files that are subject to the distributions
1111 are now named as Makefile.am.pre. These are ./Makefile.am
1112 and lib/Makefile.am. Others may be changed later.
1114 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1116 * Added invite list, ban list, some key management and connection
1117 error message printing to module formats in the Irssi SILC client.
1119 * Added new silc_client_set_away_message to set the away message
1120 that is back to the person who sent private message. The
1121 affected file lib/silcclient/silcapi.h and the
1122 lib/silcclient/client_prvmsg.c.
1124 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Fixed the private message sending in the Irssi SILC client,
1127 added local command KEY to the Irssi SILC client.
1129 Added key management and key agreement message formats to the
1130 irssi/src/fe-common/silc/module-formats.[ch].
1132 Added USERS (alias WHO) printing, server/router operator
1133 indication and LIST command printing to the module formats.
1135 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Fixed channel joining notify handling, cumode notify handling
1138 from Irssi SILC client.
1140 * Added SILC specific module-formats to the Irssi SILC client so
1141 that SILC specific message hilighting, colors etc is possible.
1142 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1144 Added channel mode, channel user mode, actions, notices,
1145 whois and whowas printing to the the module-formats.c.
1147 * Fixed a bug in channel deletion in the server. The channel
1148 is not left to the cache even if the channel founder auth mode
1149 is set when there are no users anymore on the channel. Affected
1150 file silcd/server.c.
1152 * The silc_net_localhost now resolves the entire hostname including
1153 the domain name. Affected file lib/silcutil/silcnet.c.
1155 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Changed the ask_passphrase client operation to be ascynchronous.
1158 It has now a completion callback and a context that the
1159 application must call after it has got the passphrase from
1160 the user. Affected files lib/silcclient/silcapi.h,
1161 lib/silcclient/protocol.c, lib/silcclient/command.c and
1164 Added SilcAskPassphrase callback that the application calls
1165 to deliver the passphrase to the library.
1167 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1168 The public key verification and especially a certificate
1169 verification is asynchronous procedure.
1171 Added new SILC_SKE_STATUS_PENDING status to indicate the
1172 request is pending and a callback will be called to finalize
1175 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1176 indicate that remote end did not send its public key (or
1177 certificate), even though we require it. Added check for this
1178 condition in the SKE. This was a security bug, now fixed.
1180 Defined new SilcSKEVerifyCbCompletion callback that is called
1181 when the verification process is completed.
1183 The affected files lib/silcske/silcske_status.h and
1184 lib/silcske/silcske.[ch].
1186 * Changed the verify_public_key client operation to be async
1187 as well. Defined SilcVerifyPublicKey callback that is used to
1188 indicate the success of the public key verification process.
1190 Changed the server and client to use the new async client
1193 * Changed the Irssi SILC client's internal scheduler to be called
1194 twice as many times as it used to be. As a result the client
1195 should be a bit faster now. Affected file is
1196 irssi/src/silc/core/silc-core.c.
1198 * Added support to Irssi SILC client of asynchronous public key
1199 verification and passphrase inquiry. Affected file is
1200 irssi/src/silc/core/silc-core.c.
1202 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Do not say "You have left channel %s" in client library.
1205 Moved it to the application. Affected files are
1206 lib/silcclient/command.c and silc/client_ops.c.
1208 * Fixed silc_client_get_clients. Command context was not
1209 duplicated and was freed memory in the callback. Affected
1210 file lib/silcclient/idlist.c.
1212 * Do not say "you are now talking..." on JOIN command in the
1213 client library. The appliation must handle it.
1215 * Do not say ".. changed topic to" in command reply in the
1216 client libary. The application must handle it.
1218 * Fixed TOPIC command sending in the client library.
1220 * Fixed a memory leak in silc_client_command_free in the file
1221 lib/silcclient/command.c.
1223 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Imported a modified version of Irssi client to the source tree.
1226 The Irssi will be used to create a new client called
1227 Irssi SILC. Imported to irssi/.
1229 Added silc_core_init_finish function to the Irssi. Affected
1230 file irssi/configure.in.
1232 A lot changes in the Makefile.ams around the irssi tree.
1234 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1236 * Do not rehash if the new size is same as the old size of the
1237 hash table, in the silc_hash_table_rehash*. The affected file
1238 lib/silcutil/silchashtable.c.
1240 * Replaced hash_table_del_by_context calls from the server
1241 (when channel->user_list and client->channels) to the
1242 hash_table_del as it is sufficient and faster.
1244 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Added silc_hash_table_list, silc_hash_table_get and the
1247 SilcHashTableList structure to provide an alternative way to
1248 traverse the hash table. The affected files are
1249 lib/silcutil/silchashtable.[ch].
1251 * Changed the server's idlist routines to use the hash table
1252 routines to optimize the code.
1254 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * Replaced the client entry's `channel' list and channel entry's
1257 `user_list' list to hash tables for optimized lookup. Changed
1258 the code to use the hash table interface around the code.
1259 Affected file lib/silcd/idlist.[ch].
1261 * Added `auto_rehash' boolean argument to the function
1262 silc_hash_table_alloc to indicate whether the hash table should
1263 auto-rehash when it thinks is appropriate time. It will
1264 increase the hash table size if the there is twice as much
1265 entries in the table than the size of the table, and will
1266 decrease the size if there are twice as less entries than
1267 the size of the table.
1269 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1273 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * silc_idcache_purge_by_context deletes the entry now by context
1276 as it is supposed to do. Affected file lib/silccore/idcache.c.
1278 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1279 client is not anymore valid (WHOWAS givens the info) and not
1280 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1282 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Removed the `data' and `data_len' arguments from the ID Cache
1285 interfaces and added `name' argument. ID Cache does not handle
1286 anymore the binary data only a names associated with given ID.
1288 * When hashing a Client ID with silc_hash_id the entire ID is
1289 not hashed anymore, instead only the hash of the Client ID is
1290 hashed. This way we can access the Client ID from the cache
1291 with Client ID but with the hash of the ID (which is a hash of
1292 the nickname) as well without any difference in performance.
1294 Added also silc_idcache_find_by_id_one_ext to do one on one
1295 searching when we have the actual ID. Added also function
1296 silc_hash_client_id_compare. The affected files are
1297 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1299 * When hashing the name associated with a ID it is always done
1300 in lowercase. This way we can access the cache without worrying
1301 about case-sensitivity, even though, for example nicknames are
1304 * Fixed a bug in server with channel message sending. It put
1305 wrong ID type as destination ID. The affected file
1306 silcd/packet_send.c.
1308 * silc_idcache_del_by_context now deletes from all hash tables
1309 by context. Affected file lib/silccore/idcache.c.
1311 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1313 * Changed the client library to use the new ID Cache interface.
1314 Changes around the source tree.
1316 * Added silc_hash_table_rehash_ext to rehash with specific
1317 hash function. Affected file lib/silcutil/silchashtable.[ch].
1319 * Added silc_hash_string_compare to compare two strings in the
1320 hash table. Affected file lib/silcutil/silcutil.[ch].
1322 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Added new function silc_idcache_del_by_context into the
1325 lib/silccore/idcache.[ch].
1327 * Changed the server's ID list routines to use the new ID Cache
1328 interface. Changes around the source tree.
1330 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Added silc_hash_table_del[_by_context]_ext functions in to the
1333 lib/silcutil/silchashtable.[ch].
1335 Removed silc_hash_table_find_all* routines and added new
1336 silc_hash_table_find_foreach to replace them.
1338 Added silc_hash_table_replace_ext function as extended
1339 replacing function. Separated the simple hash table interface
1340 from the extended hash table interface in the file
1341 lib/silcutil/silchashtable.h.
1343 * Fixed minor bugs and changed it to use some of the new
1344 hash table functions in lib/silccore/idcache.c
1346 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Added new function silc_hash_table_find_all to return all keys
1349 in the hash table by the specified key. As the hash table is
1350 collision resistant it also makes it possible to have several
1351 duplicate keys in the hash table. This function may be used to
1352 find all of the keys from the hash.
1354 Added user_context arguments to the SilcHashFunction,
1355 SilcHashCompare and SilcHashDestructor to deliver user specified
1358 Added new fuctions silc_hash_table_find[_all]_ext to do
1359 extended lookup with specified hash and compare functions and
1360 specified user contexts.
1362 Added new function silc_hash_table_add_ext to add the key
1363 with specified hash function and user context.
1365 Added new function silc_hash_table_foreach to traverse all
1366 entrys in the hash table. Added SilcHashForeach callback
1369 Added new function silc_hash_table_del_by_context to delete
1370 the entry only if the context associated with the key matches.
1372 Affected files are lib/silcutil/silchashtable.[ch].
1374 * Removed silc_hash_[server/client/channel]_id and added just
1375 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1376 silc_hash_id_compare to compare two ID's using as the hash table
1377 comparison function. Added also silc_hash_data to hash
1378 binary data and silc_hash_data_compare to compare it.
1380 * Removed silc_idlist_find_client_by_hash as it is not needed
1381 anymore. Affected file silcd/idlist.[ch].
1383 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1384 to use internally the SilcHashTable. The new ID Cache is a lot
1385 faster than the old one. Some of the ID Cache interface was also
1386 rewritten and obsolete and stupid functions were removed.
1388 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Added entry_count field to the SilcHashTable to keep the number
1391 of the entries in the table. Implemented the function
1392 silc_hash_table_rehash. Added new function
1393 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1395 Fixed a minor bug in silc_hash_table_free.
1397 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1398 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1399 into the lib/silcutil/silcutil.[ch].
1401 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Implemented a collision resistant hash table into the
1404 lib/silcutil/silchashtable[ch]. See the header and the source
1405 for the SilcHashTable API.
1407 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Merged dotconf version 1.0.2 into lib/dotconf.
1411 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Do not compile anything in lib/silcsim/* if the SIM support
1414 is not enabled. The tree should now compile without problems
1417 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Compiled the SILC under cygwin. Compiled and tested briefly
1420 without problems. More tests needed. The SIMs didn't compile
1423 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1425 * Fixed possible crash in silc_get_username in the
1426 lib/silcutil/silcutil.c.
1428 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Fixed a va_arg in silc/client_ops.c.
1432 * Oops, RC5 routines were named AES and caused some problems
1433 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1435 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Added new SilcIDIP structure into the lib/silccore/id.h and
1438 replaced the old `ip' fields from all SILC ID's to that type.
1439 This is a step towards IPv6 support.
1441 The silc_id_get_len takes now the ID as an extra argument.
1442 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1443 both IPv4 and IPv6 based ID's.
1445 The affected files are lib/silccore/id.[ch] and other files
1446 around the tree using these routines.
1448 * Removed the ID length arguments in server from various
1449 silc_server_send_notify_* routines -> they are not needed
1452 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Fixed memory leak in silc_encode_pem_file in the file
1455 lib/silcutil/silcutil.c.
1457 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * Check minor version as well in the SKE. Affected files are
1460 silcd/protocol.c and lib/silcclient/protocol.c.
1462 * Added --identifier option to the server so that an identifier
1463 can be when creating the public key for the server. Affected
1464 file is silcd/silcd.c.
1466 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1467 lib/silccrypt/silcpkcs.c.
1469 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Register default ciphers and stuff when using -C option with
1472 the server. Affected file sildc/silcd.c.
1474 * Put back the servers public key filename format, it is better
1475 than the new one. For now, the client keys are saved with the
1476 new filename format. The affected file silc/client_ops.c.
1478 * Implemented the Cipher API for the rest of the ciphers that
1479 did not implement it or implemented it the wrong way.
1481 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Register default ciphers and stuff when using the -S option
1484 in the client. Affected file silc/silc.c. Same also when
1485 creating new key pair with -C option.
1487 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Fixed the silc_verify_public_key client operation function to
1490 save the public keys differently. The fingerprint is now
1491 used as filename and not the hostname. This way also the
1492 client keys are saved uniquely and not with hostnames. The
1493 affected file is silc/client_ops.c.
1495 * Trimmed the silc_hash_fingerprint function to remove extra
1496 whitespaces from the end of the fingerprint. The affected
1497 file is lib/silccrypt/silchash.c.
1501 * Added silc_cipher_register_default function to register all
1502 default ciphers. It can be used when configuration files
1503 does not exist and the application does not want any specific
1504 ciphers in any specific order.
1506 The SilcDList is now used as silc_cipher_list dynamically
1507 allocated cipher list. Removed the static list all together
1508 and now all ciphers must be allocated to the dynamic list.
1509 The silc_cipher_alloc routine was changed to check only the
1512 All silc_cipher_* routines that used to return int returns
1515 The affected files lib/silccrypt/silccrypt.[ch].
1517 * The same thing was done to silc_hash_* as for silc_cipher_*
1518 routines. Affected files lib/silccrypt/silchash.[ch].
1520 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1521 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1522 Added also silc_pkcs_[un]register[_default] functions.
1523 Removed the data_context from the PKCS API.
1525 * Added silc_hmac_register_default function to register default
1526 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1527 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1528 to unregister all hmacs at once.
1530 * Register the default ciphers, hash functions, PKCSs and HMACs
1531 if client's configuration file does not exist. The affected
1534 * The client did not load the hash functions from the SIM
1535 modules at all. Added support for this. Affected file is
1536 silc/clientconfig.c.
1538 * When decoding public key with silc_pkcs_public_key_decode, check
1539 the supported algorithm only if PKCS are registered. Affected
1540 file lib/silccrypt/silcpkcs.c. The same was done with the
1541 silc_pkcs_private_key_decode.
1543 * Fixed the SILC List routines to keep the list always in order.
1544 It used to change the list's order when traversing the list but
1545 not it preserves the order. Affected file lib/trq/silclist.h.
1547 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1549 * Added the client library to use the SilcSocketConnection's
1550 reference counter (by silc_socket_dup) to prevent the bug that
1551 the socket object may be freed underneath async operation.
1553 * The name resolv library checking fixes in the configure.in.pre.
1556 * Created new version of the protocol drafts for future
1557 development. The -03 drafts are the ones that will be changed
1558 in the trunk now and the -02 will remain as they are.
1560 * Send list of CUMODE notifys to the router when announcing
1561 the channel users to the router. Affected file silcd/server.c.
1562 If the router receiving channel founder CUMODE for a channel
1563 that already has channel founder it will send CUMODE notify
1564 to the sender to remove the channel founder rights from the
1565 announced client. Affected file silcd/packet_receive.c.
1567 * The CUMODE notify may now use Server ID as well as the entity
1568 who changes the mode. Updated protocool specs.
1570 * Updated INSTALL and README files.
1572 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * New web pages in the http://silc.pspt.fi. The pages was
1579 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Implemented the [DenyConnectin] config section in the server.
1582 Added silc_server_config_denied_conn to check whether incoming
1583 connection is denied. Affected file silcd/serverconfig.[ch].
1585 * Do not check the ports when checking the incoming configuration
1586 data if the port is 0, meaning any. Affected file is
1587 silcd/serverconfig.c.
1589 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1591 * Fixed buffer overflow in silc_string_compare in the file
1592 lib/silcutil/silcutil.c.
1594 * Fixed double free in silc_server_command_leave in the file
1597 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * Fixed the version checking in the server. Affected file is
1602 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Fixed the configuration data fetching when accepting new
1605 connections in the server. Affected file silcd/server.c.
1607 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Added `sender_entry' argument to the function
1610 silc_server_packet_relay_to_channel so that we can check
1611 whether some destination actually belongs to the same route
1612 the sender belongs (ie, we must not resend the packet to the
1613 sender). Affected file silcd/packet_send.[ch].
1615 * Added `servername' field to the SilcClientEntry in the server
1616 to hold the name of the server where client is from. Affected
1617 file is silcd/idlist.h.
1619 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1621 * Moved the channel message encrypting in the router betwen
1622 router connections from silc_server_channel_message to the
1623 silc_server_packet_relay_to_channel since we want to check
1624 whether we have anybody channel before encrypting anything.
1625 Affected files silcd/packet_[receive/send].c.
1627 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Fixed the [AdminConnection] server config section to support
1630 multiple entries. Affected file silcd/serverconfig.c.
1632 * Added support into the server to check the validity of the
1633 incoming connection before executing any KE or authentication
1636 * The connection configuration is now saved to the KE and
1637 connection auth protocol contexts and not fetched anymore in
1638 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1640 * The local hosts listenning address and port is also resolved
1641 now when starting the server. We want to have the socket object
1642 to include the real address and port for the listener. Added
1643 new function silc_net_check_local_by_sock into the files
1644 lib/silcutil/silcnet.[ch].
1646 * Fixed a broadcast bug in server -> do not broadcast if we
1649 * Fixed a routing bug. Do not route broadcast packets ever.
1650 Broadcast packets must be processed always and not routed since
1651 they may be destined to some other host than yourself and thus
1652 would get routed without no good reason. Affected file is
1655 * Added function silc_server_config_is_primary_route to check
1656 whether primary router connection has been configured (a router
1657 configuration that we are initiating). If there is not, we
1658 will assume that there is only two routers in the SILC network
1659 and we will use the incoming router connection as our primary
1660 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1662 * Changed the order of the broadcasting. Broadcast _after_ the
1663 packet has been processed not before. Affected file is
1666 * Fixed a [ClientConnection] parsing bug. The port was never
1667 parsed correctly thus resulting to port 0. Affected file
1668 silcd/serverconfig.c.
1670 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1671 argument and did not set the broadcast packet flag. Affected
1672 file silcd/packet_send.c. Fixed same bug in the function
1673 silc_server_send_notify as well.
1675 * If we receive NEW_ID packet for our own ID in the server, ignore
1678 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Removed the nickname from the Private Message Payload.
1683 Updated the code and the protocol specs.
1685 * Updated protocol specs for submitting to the IETF.
1687 * Tweaked the Random Number Generator a bit. Affected file
1688 lib/silccrypt/silcrng.c. Exported a new function
1689 silc_rng_[global]_add_noise which can be used to add more
1692 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Do not parse packets with different timeout when protocol
1695 is active -> may cause problem with rekey. Affected file
1698 * When server receives signoff notify it must not create
1699 new channel key if the client is on any channels since the
1700 sender of the signoff notify will create it.
1702 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Added printing of error messages during SKE protocol from the
1705 failure packet sent by server during SKE. Affected file
1708 * Removed the client's failure_callback handling with timeout
1709 and handle it immediately when received.
1711 * The SKE library returned wrong type in SUCCESS and FAILURE
1712 packets. They must be 32 bit MSB not 16 bit MSB.
1714 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Ok, rewrote the logic of the re-key and now it seems to work.
1717 I tested it on high traffic with frequent re-keys without
1718 problems. Added hmac_receive (and renamed hmac to hmac_send)
1719 in SilcClientConnection in lib/silcclient/client.h and
1720 in SilcIDListData in silcd/idlist.h. Also, removed the
1721 SilcPacketParserContext's cipher and hmac fields as they are
1722 not needed anymore and actually caused some problems when
1723 the ciphers and hmac's changed underneath the packet parser.
1725 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1727 * If re-key protocol is active then process the incoming packets
1728 synchronously since we must assure that icoming packets encrypted
1729 with the old key is processed before the new keys is set to
1730 use. This is true other packets than for REKEY packets.
1731 Affected file silcd/server.c. The same was done to client library
1732 as well, affected file lib/silcclient/client.c.
1734 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Fixed bug in client and server to accept the force send if
1737 the packet is send from silc_[server/client]_packet_process
1738 function. Otherwise the packets are never delivered, oops.
1740 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Disable force sending of packets when REKEY protocol is active.
1743 We must assure that no packet is sent directly when rekey is
1744 performed. All packets must be sent through packet queue.
1745 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1746 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1747 function is silc_[server/client]_packet_send_real to check
1750 * Replaced the SIM paths from example config files to
1751 /usr/local/modules. Also, make install creates now
1752 /usr/local/silc/logs directory to hold all the SILC server
1755 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Made the configure.in.pre work on Solaris. Patch by salo.
1759 * Made all ciphers compatible with non-x86 machines. Defined
1760 CBC mode macros into lib/silccrypt/ciphers_def.h.
1762 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Fixed the make install.
1766 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1768 * When MAC computation fails the silc_packet_decrypt returned 0
1769 even though it was supposed to return -1. Fixed this. The
1770 affected file is lib/silccore/silcpacket.c.
1772 * Do not replace the config files in /etc/silc (in make install)
1773 if they already exist. Affected file ./Makefile.am.
1775 * Do not send re-key packets immediately but through packet queue.
1776 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1778 * Changed silc_net_check_host_by_sock to return FALSE if the
1779 IP/DNS could not be resolved. Though, it returns the IP address
1780 now even if it could not resolve it (but returns also FALSE).
1781 Affected file lib/silcutil/silcnet.[ch].
1783 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Added silc_pkcs_decode_identifier to decode the public key's
1786 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1787 Added also silc_pkcs_free_identifier. Added also new context
1788 SilcPublicKeyIdentifier.
1790 * Added -S option to the silc client. It is used to dump the
1791 contents of the specified public key file.
1793 * Changed the PKCS api to return the public key length when
1794 setting the public key.
1796 * Fixed a fatal bug in the public and private key file loading.
1797 Affected file lib/silccrypt/silcpkcs.c.
1799 * Execute the packet parsing for client with zero (0) timeout
1800 if the protocol is active. Affected file silcd/server.c.
1802 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1804 * Made the key generation options to the silcd program. Added
1805 -C option, equivalent to client's option.
1807 * Added new [ServerKeys] config section to the server. It
1808 configures the server's public and private key.
1810 * Defined generic Public Key Payload into the protocol
1811 specification to send specific type of public keys and
1814 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1815 public key or certificate.
1817 * Implemented the GETKEY command to the server and to the
1818 client library and on user interface.
1820 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1822 * Made preliminary `make install' work.
1824 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1826 * Added SilcServerRekey context into silcd/idlist.h.
1828 * Added the PFS support as defined in the specification to the
1829 SKE protocol. Affected files lib/silcske/*.c.
1831 * Added `ske_group' field to the SilcServerRekey context to hold
1832 the number of the SKE group that is used with PFS in re-key.
1833 Affected file silcd/idlist.h.
1835 * Added PFS re-key support to the server. Affected file is
1838 * Added silc_protocol_cancel to cancel execution of the next
1839 state of the protocol. Affected file is
1840 lib/silccore/silcprotocol.[ch].
1842 * Added the re-key support with and without PFS to the client
1843 library. Re-key is performed once in an hour, by default.
1845 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1846 Added silc_client_rekey_callback and silc_client_rekey_final.
1847 Affected files are lib/silcclient/protocol.[ch] and
1848 lib/silcclient/client.[ch].
1850 * Removed the `hmac_key' and `hmac_key_len' fields from the
1851 SilcClientConnection structure; not needed. Affected file is
1852 lib/silcclient/client.h.
1856 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Do not ask whether user wants to use the negotiated private key
1859 for private messages, just use it. Affected file is
1860 silc/local_command.c.
1862 * Added `send_enc_key' and `enc_key_len' fields to the
1863 SilcIDListData structure since they are needed in the re-key
1864 phase. Affected file is silcd/idlist.[ch].
1866 * Implemented the simple re-key protocol into the server.
1867 Affected files silcd/server.c and silcd/protocol.[ch]. The
1868 re-key will be performed once in an hour, by default.
1870 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1871 Added silc_server_rekey, silc_server_rekey_callback and
1872 silc_server_rekey_final.
1874 * Removed Tunneled flag from the protocol. Updated the code
1875 and the specifications.
1877 * Adde `pfs' field to the SilcIDListData to indicate whether
1878 the PFS is to be performed in the re-key. Affected file is
1881 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1884 int64 of at least the xintXX size. If void * is less that 4
1885 bytes uint32 * will be used. Defined bool as boolean.
1887 * Changed _ALL_ unsigned long and unsigned int to uint32,
1888 unsgined short to uint16 in the source tree.
1890 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1891 not handle clients that has entry->data.registered == FALSE.
1892 They are not in the network anymore. Affected file is
1895 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Implemented the sending of the SERVER_SIGNOFF notify in the
1898 server. Affected file is silcd/server.c.
1900 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1901 Added also silc_notify_payload_encode_args into the
1902 lib/silccore/silcnotify.[ch].
1904 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1905 Affected file silcd/packet_receive.c.
1907 * Implemented the SERVER_SIGNOFF notify handling in the client
1908 library. Affected file lib/silcclient/client_notify.c. Also,
1909 implemnted the printing of the SERVER_SIGNOFF info to the
1910 application. Affected file silc/client_ops.c.
1912 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1913 if the deleting was successful. Affected file silcd/idlist.[ch].
1915 * Added support for public key authentication in the connection
1916 authentication protocol in the client library. Affected file
1917 lib/silcclient/protocol.c.
1919 * Changed the server's silc_idlist_get_clients_by_* interface
1920 to support already allocated array so that new entries may be
1921 added to pre-allocated array. Affected file silcd/idlist.[ch].
1922 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1923 and command replies.
1925 * All command reply functions in the server now calls the
1926 pending command callback even if error occured. This way the
1927 error will be delivered to the client as well. Affected files
1928 silcd/command.c and silcd/command_reply.c.
1930 * Fixed INFO command to return local server's info if no server
1931 was provided. Affected file lib/silcclient/command.c.
1933 * Removed RESTART command for good. Updated the code and the
1936 * Rewrote parts of the task system. It is a bit simpler now.
1937 Removed unsued task priorities. The affected files are
1938 lib/silcutil/silctask.[ch].
1940 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Moved the USERS printing from the library to the application.
1943 Affected files lib/silcclient/command.c and silc/client_ops.c.
1945 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Added channel key re-key support. The re-key is perfomed
1950 only by the router and is done once in an hour. Added `rekey'
1951 field to the SilcChannelEntry in the server. Affected files
1952 silcd/server.c and silcd/idlist.h.
1954 * Added silc_task_unregister_by_context into the file
1955 lib/silcutil/silctask.[ch].
1957 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Added SILC_UMODE_GONE mode to indicate when the client is not
1960 present in the SILC network. Added also support to the local
1961 command AWAY that will set this mode. Added support of showing
1962 "xxx is gone" in WHOIS command. The USERS command shows the
1963 gone status as well.
1965 * Fixed setting server and router operator privileges in the
1966 server's UMODE command. Affected file silcd/command.c.
1968 * Merged the SKE KE1 and KE2 payloads into one payload. The
1969 new KE payload is equivalent to the old KE2 payload.
1971 Cleaned up the SKE Start Payload parsing. It now uses the
1972 simple buffer unformatting to do the parsing. A lot faster
1975 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1976 to the SKE that is used to indicate whether both of the SKE
1977 parties should perform authentication. By default only the
1978 responder performs authentication. By setting this flag also
1979 the initiator must do authentication. By default it is unset
1980 since in normal SKE case, client to server connection, only
1981 the responder should do authentication. When doing SKE between
1982 two clients both should perform authentication. Updated the
1983 code and the protocol specs.
1985 * A little fix to IDENTIFY command in the server. Search the
1986 client first by hash not nickname. Affected file is
1989 * Fixed the silc_client_close_connection to support closing
1990 the client to client connections wihtout deleting too much
1991 data. Affected file lib/silcclient/client.c.
1993 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1994 are received if protocol used to be active but is not anymore
1995 the application would crash due to NULL pointer dereference.
1996 Affected files silcd/server.c and lib/silcclient/client.c.
1998 * Added `hash' field to the SilcClientConnection to include
1999 the hash function negotiated in the SKE protocol.
2001 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2002 to set the channel founder authentication data. A client can
2003 claim the founder rights later by providing the authentication
2004 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2005 This way the channel founder can regain the channel founder
2006 privileges even it is left the channel. This works only on
2007 local server and the client must be connected to the same
2008 server to be able to regain the founder rights. Updated the
2009 protocol specs accordingly.
2011 Added support to the CMODE command in the client to set the
2012 founder auth data. Read the README to see how to set it.
2014 Added support to the CUMODE command to claim the founder
2015 rights. Read the README to see how to do it.
2017 Added support for the founder authentication to the Channel
2018 Entry in the server. Affected file silcd/idlist.h.
2020 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2021 server's CMODE command. Affected file silcd/command.c.
2023 * Added the following new functions into lib/silccore/silcauth.[ch]:
2024 silc_auth_get_method and silc_auth_get_data.
2026 * The server now saves the remote hosts public key to the
2027 SilcIDListData pointer. Affected file silcd/protocol.c.
2029 * The normal server now does not remove the channel entry from
2030 the cache if the founder authentication data is set. It used
2031 to remove it if the founder was the last one on the channel on
2032 the server and left the channel. The auth data is saved and
2033 if the channel is re-joined later the old entry is used with
2034 the old auth data. Affected files silcd/command_reply.c and
2037 * Removed the `pkcs' field from the SilcIDListData structure
2038 in the server; it is not used. Affected file silcd/idlist.h.
2040 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2042 * Fixed packet processing on slow links. Partial packets were
2043 never re-processed because the incoming data buffer was cleared
2044 by the application. Application must not directly clear the
2045 sock->inbuf, the packet processing routines handle it. Fixed
2046 this in client library and in server.
2048 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Fixed the WHOIS and IDENTIFY send reply function to really
2051 check whether to send list or just one entry. Affected file
2054 * Cleaned up the LEAVE command's channel key distribution. The
2055 affected file silcd/command.c.
2057 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2058 can enforce the channel mode as well. In that case the ID
2059 includes the ID of the server. The code now enforces the
2060 mode change if the router have different mode than the server.
2062 * The notify client operation with CMODE_CHANGE notify can now
2063 return NULL client_entry pointer if the CMODE was not changed
2064 by client. Application must check for this.
2066 * Added <Server ID> argument to INFO command to support server
2067 info fetching by Server ID.
2069 * Added silc_server_announce_get_channel_users to get assembled
2070 packets of channel users of the specified channel. Affected
2071 file silcd/server.[ch].
2073 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2074 was freed underneath the ID Cache.
2076 * Re-announce clients when the server received CHANNEL_CHANGE
2077 notify from the router. Affected file silcd/packet_send.c.
2079 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2082 crashed since it did not handle the fact that there is no cipher
2083 called "3" and didn't check the error condition. Now fixed.
2085 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2086 flag. It can be used to send message requests.
2088 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Implemented the RESTART command in the client.
2092 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2093 notice type messages. Added notice printing to the user
2096 * The channel keys are not re-generated if the channel's mode
2097 is PRIVKEY, ie private key on the channel exists. Affected
2098 files silcd/server.c and silcd/command.c.
2100 * Fixed a little bug in channel message delivery when channel
2101 private keys are set in the server. Affected file is
2102 silcd/packet_send.c.
2104 * Changed the setting on channel->on_channel = TRUE from the
2105 silc_client_save_channel_key to the JOIN command reply. The
2106 key payload is not received if the private channel key is set.
2107 Affected file lib/silcclient/command_reply.c and the
2108 lib/silcclient/client_channel.c.
2110 * When the CMODE_CHANGE notify is sent and the channel private
2111 key mode is removed the channel key must be re-generated in
2112 other cells as well. Added this support for the router in the
2113 silcd/packet_receive.c.
2115 * Added new local command NOTICE to send notice message on
2116 channel. Affected file silc/local_command.[ch].
2118 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Added new local command ME to the client. It is used to send
2121 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2122 some action. Affected file silc/local_command.[ch].
2124 * Changed channel_message and private_message client operations
2125 to deliver the message flags to the application. Added also
2126 the `flags' arguments to the silc_client_send_channel_message
2127 and silc_client_send_private_message functions. Affected file
2130 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Redefined the Private Message Payload to support private message
2133 keys and to support the new private message flags. Updated
2134 the protocol specs. Flags makes it possible to have for example
2135 CTCP style messages.
2137 * Added new type SilcPrivateMessagePayload and defined an API
2138 for it in the lib/silcclient/silcprivate.[ch].
2140 * Tested private message private keys successfully. Tested the
2141 private message key set, unset and list commands with the new
2144 * Redefined the Channel Message Payload to include the channel
2145 message flags (equal with private message flags) to support
2146 for example CTCP style messages.
2148 * Defined some of the message (for channel and private message)
2149 flags. Updated the protocol specs and added the flags to the
2150 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2152 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Added SilcKeyAgreementStatus type to the key agreement routines
2155 to indicate the current status and error if one occured.
2156 The status types are defined in the lib/silcclient/silcapi.h.
2158 * Added new local command KEY that is used to set and unset private
2159 keys for channels, set and unset private keys for private messages
2160 with remote clients and to send key agreement requests and
2161 negotiate the key agreement protocol with remote client. The
2162 key agreement is supported only to negotiate private message keys,
2163 it currently cannot be used to negotiate private keys for channels,
2164 as it is not convenient for that purpose.
2166 * Fixed a minor pending callback setting bug in the function
2167 silc_client_get_client_by_id_resolve, now the function works.
2168 Affected file lib/silcclient/idlist.c.
2170 * Added function silc_net_get_local_port to get local bound
2171 port by socket. Added to lib/silcutil/silcnet.[ch].
2173 * Added `sockets' and `sockets_count' fields to the SilcClient
2174 object. They hold the sockets of the listenning sockets in
2175 the client. Listenning sockets may be for example the key
2176 agreement server. Affected file lib/silcclient/client.[ch].
2177 Added functions the silc_client_add_socket and the
2178 silc_client_del_socket. They are exported to the application
2181 * Added ~./silc/clientkeys to support other client's public keys.
2183 * Renamed verify_server_key client operation to verify_public_key
2184 and added one argument to indicate the type of the connection
2185 (server, client etc.).
2187 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Added silc_server_connection_auth_request to handle the
2190 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2191 silcd/packet_receive.[ch].
2193 * Added silc_server_send_connection_auth_request into the
2194 silcd/packet_send.c to send the connection auth request packet.
2196 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2199 * Fixed the public key authentication in responder side in the
2200 server. The `auth_data' pointer includes the SilcPublicKey
2201 not the path to the public key. Affected file silcd/protocol.c.
2203 * Implemented the public key authentication in the initiator side
2204 in the server. Affected file silcd/protocol.c.
2206 * Removed the [RedirectClient] config section from the server
2207 configuration. Is not needed and I don't want to implement it.
2209 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Cleaned up the CMODE command in the server. It now works
2212 correctly and supports all the modes defined in the protocol.
2213 Affected file is silcd/command.c.
2215 * Added `hmac_name' field to the SilcChannelEntry in the server
2216 to hold the default HMAC of the channel. It can be set when
2217 creating the channel (with JOIN command). Affected files
2220 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2221 type to indicate the change of the current cipher and hmac
2222 on the channel. Client can safely ignore the <cipher> argument
2223 (if it chooses to do so) since the CHANNEL_KEY packet will
2224 force the channel key change anyway. The <hmac> argument is
2225 important since the client is responsible of setting the new
2226 HMAC and the hmac key into use.
2228 * Fixed the CMODE command in the client library as well.
2230 * Tested CMODE command in router environment successfully.
2232 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Show the version of the remote client (or server) when connecting
2235 to the server. It is logged to the log file. Affected file
2236 is silcd/protocol.c.
2238 * Fixed the KILLED notify handling in the client library. The
2239 client must be removed from all channels when receiving the
2242 Also, do not remove the client entry when giving the KILL
2243 command but when the KILLED notify is received.
2245 * Removed silc_idlist_find_client_by_nickname from the server.
2246 Not needed anymore. Affected files silcd/idlist.[ch].
2248 * Implemented the CHANNEL_CHANGE notify type handling to the
2249 server. Affected file silcd/server.c.
2253 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Added silc_server_send_notify_invite to send the INVITE
2256 notify between routers.
2258 * Implemented the INVITE command correctly to the server.
2260 * Implemented the INVITE notify type handling in the server.
2262 * Implemented the INVITE command to the client library and on the
2265 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Added function silc_server_get_client_resolve to find the
2268 client entry by ID from all ID lists and then resolve it
2269 (using WHOIS) if it cannot be found. Affected file is
2272 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Implemented the BAN command to the client library.
2276 * The JOIN command in the server now checks the invite list
2279 * Changed the silc_command_reply_payload_encode_va and the
2280 silc_command_payload_encode_va to support that if argument is
2281 NULL it ignores and checks the next argument. Affected file
2282 lib/silccore/silccommand.c.
2284 * Added silc_server_send_notify_ban to send the BAN notify
2285 type between routers.
2287 * Chaned the silc_notify_payload_encode to support that if
2288 argument is NULL it ignores and checks the next argument.
2289 Affected file lib/silccore/silcnotify.c.
2291 * Tested ban lists in router environment successfully.
2293 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Implemented BAN command to the server, in silcd/command.[ch].
2297 * Removed the BAN and INVITE_LIST modes from the CMODE command
2300 * Added function silc_string_match to regex match two strings.
2301 Affected files lib/silcutil/silcutil.[ch].
2303 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Redefined parts of the SilcChannelEntry in the server to support
2306 the new ban and invite lists.
2308 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Redefined the INVITE command. The same command can be used to
2311 invite individuals to the channel but also to manage the invite
2312 list of the channel (to add to and remove from the invite list).
2313 Updated the protocol specs.
2315 * Added new command SILC_COMMAND_BAN that can be used to manage
2316 the ban list of the channel. Updated the protocol specs.
2318 * Removed the channel modes: the SILC_CMODE_BAN and the
2319 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2320 in the CMODE command. The equivalent features are now available
2321 using INVITE and BAN commands. Updated the protocol specs.
2323 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2324 in the network about change in the current ban list. The notify
2325 type is not used by the client.
2327 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2328 support the invite lists.
2330 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Added new function silc_string_regexify that converts string
2333 including wildcard characters into regex string that can
2334 be used by the GNU regex library. Added into the file
2335 lib/silcutil/silcutil.[ch].
2337 Added silc_string_regex_combine to combine to regex strings
2338 into one so that they can be used as one regex string by
2339 the GNU regex library. Added into the file
2340 lib/silcutil/silcutil.[ch].
2342 Added silc_string_regex_match to match two strings. It returns
2343 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2345 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Imported GNU regex to the soruce tree into lib/contrib.
2348 Fixed some compiler warning from the regex.c.
2350 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Fixed MOTD command in the server to work in router environment.
2354 * Fixed the MOTD command in the client library to support
2355 the server argument in the command.
2357 * Added `nickname_len' argument to the silc_idlist_add_client
2358 in the server, as the `nickname' argument may be binary data
2361 * Added silc_idlist_get_channels to return all channels from
2364 * Implemented LIST command to the server. Affected file is
2367 * Implemented the LIST command to the client library and on the
2370 * Added [<user count>] argument to the LIST command reply.
2371 With private channels the user count is not shown.
2373 * Updated TODO and README.
2375 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * The client entry's data.registered must be TRUE even with
2378 global client entry on global client list. The data.registered
2379 is used to check whether the client is anymore in the network,
2380 for example with WHOWAS command so it must be valid.
2382 * Fixed the WHOWAS command in the server. It now actually works
2383 in router environment. Added function into silcd/command_reply.c
2384 silc_server_command_reply_whowas_save.
2386 * Added silc_idlist_purge function to the silcd/idlist.c
2387 to periodically purge the ID Cache.
2389 * Fixed INFO command in the server. It works now in router
2390 environment. Added <server name> argument to the INFO command
2391 reply. Updated the protocol specs.
2393 * Fixed minor bug in silc_idcache_purge to not purge if the
2394 expire value is zero.
2396 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2397 they were buggy because of the WHOWAS information.
2399 * Fixed local command MSG to handle the async resolving of
2400 the remote client properly. It used to fail the first MSG.
2401 Affected file silc/local_command.c.
2403 * Added `data_len' field to SilcIDCache context.
2405 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Update TODO. Todo in commands in the server.
2409 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2412 used by routers as broadcast packet to inform other routers
2413 about the changed user mode.
2415 Implemented the notify handling in the server. Affected file is
2416 silcd/packet_receive.c. Added the function
2417 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2419 * Added new generic Channel Payload and deprecated the New Channel
2420 Payload. The New Channel Payload is now the generic Channel
2423 * Added new argument `mode' to the silc_server_send_new_channel
2424 as it is required in the Channel Payload now.
2426 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2427 and created a new and real SilChannelPayload to represent the
2428 new generic Channel Payload. Implemented the encode/decode
2429 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2431 * Added silc_server_get_client_channel_list to return the list
2432 of channels the client has joined for WHOIS command reply.
2433 Affected file silcd/server.[ch].
2435 * Implemented the channel list sending in the WHOIS command reply
2436 in server and in the client.
2438 Implemented the channel list displaying on the user interface
2439 as well. Affected file silc/client_ops.c.
2441 * Added silc_channel_payload_parse_list to parse list of Channel
2442 Payloads. It returns SilcDList list of SilcChannelPayloads.
2443 Client for example can use this function to parse the list of
2444 channels it receives in the WHOIS command reply. The caller
2445 must free the list by calling silc_channel_payload_list_free.
2446 Affected files lib/silccore/silcchannel.[ch].
2448 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Added one new argument <user mode> to the WHOIS command reply
2451 to return the mode of the user in SILC. Updated the protocol
2454 Implemented it to the server and client.
2456 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2458 * Fixed the mode printing on the user interface on joining.
2459 Affected file silc/client_ops.c.
2461 * Implemented the UMODE command and user modes in general to the
2462 client library and to the user interface.
2464 * Implemented the UMODE command to the server.
2466 * The server now sends UNKNOWN_COMMAND error status if client sends
2467 unknown command. Affected file silcd/command.c.
2469 * All server commands now handle the command identifier the right
2470 way when sending the command reply to the client. The client can
2471 use to identify the command replies with the identifier.
2473 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added silc_server_get_client_route to resolve the route to
2476 the client indicated by the client ID. Affected file is
2479 * Added silc_server_relay_packet as general function to relay
2480 packet to arbitrary destination. This deprecates functions
2481 like _send_private_message_key, _relay_notify etc. Affected
2482 file is silcd/packet_send.[ch].
2484 Removed silc_server_send_key_agreement,
2485 silc_server_send_private_message_key and
2486 silc_server_packet_relay_notify functions from the file
2487 silcd/packet_send.[ch].
2491 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2492 server. Affected file silcd/packet_receive.[ch].
2494 * Implemented the KILL command to the client. Implemented the
2495 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2496 Affected files lib/silcclient/command[_reply].c and
2497 lib/silcclient/client_notify.c. Implemented the KILL notify
2498 printing in the user inteface.
2500 * Fixed a lot silc_parse_nick memory leaks from the client
2501 library in the file lib/silcclient/command.c.
2503 * Changed the silc_server_send_notify_on_channels's `sender'
2504 argument from SilcSocketConnection to SilcClientEntry to
2505 check the sender as entry and not as connection object and not
2506 to send to the client provided as argument. The affected file
2507 is silcd/packet_send.[ch].
2509 * The notify packets that are destined directly to the client used
2510 to not to be processed by the server. Now changed that and the
2511 server processes all notify packets. After relaying the packet
2512 to the client the notify packet is processed in the server.
2514 * The silc_server_free_client_data now checks whether there is
2515 pending outgoing traffic for the client and purges the data to
2516 the network before removing the client entry.
2518 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2521 an client is killed from the SILC Network. Updated the protocol
2524 Added new function silc_server_send_notify_killed to the
2525 silcd/packet_send.[ch].
2527 * Added function silc_server_packet_relay_notify to relay notify
2528 packets that are destined directly to a client. In this case
2529 the server does not process the notify packets but merely relays
2530 it to the client. Affected file silcd/packet_send.[ch].
2532 Added also silc_server_packet_process_relay_notify to check
2533 whereto relay the notify. Affected file is
2534 silcd/packet_receive.[ch].
2536 * Implemented the KILL command to the server.
2540 * Added the backup schema desgined last fall to the protocol
2541 specs for everyone to see. The specification is in the
2542 *-spec-xx.txt draft and the packet type definitions for the
2543 backup routers is in *-pp-xx.txt draft. Thusly, added also
2544 new packet type SILC_PACKET_CELL_ROUTERS.
2546 * A big security problem in the implementation discovered. The
2547 signoff of an client did not cause new channel key generation
2548 which it of course should've done. The channel keys must be
2549 always re-generated when client leaves (or signoffs) the channel.
2550 The silc_server_remove_from_channels funtion now handles
2551 the channel key re-generation.
2553 * Added `sender' argument to the silc_server_send_notify_on_channels
2554 to not to send the client provided as argument. Affected file
2555 silcd/packet_send.[ch].
2557 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Implemented OPER and SILCOPER commands into the server and
2562 * Added silc_auth_verify and silc_auth_verify_data to verify
2563 the authentication directly from the authentication payload.
2564 It supports verifying both passphrase and public key based
2565 authentication. Affected file lib/silccore/silcauth.[ch].
2567 * Added `hash' field to the SilcIDListData structure. It is the
2568 hash negotiated in the SKE protocol. Affected file is
2571 * Slight redesigning of the SilcAuthPayload handling routines.
2572 Do not send SilcPKCS but SilcPublicKey as argument.
2574 * Implemented the public key authentication support to the
2575 serverconfig. The public key is loaded from the provided path
2576 and saved as authentication data to void * pointer. Thus,
2577 changed the unsigned char *auth_data to void *auth_data;
2579 * Fixed SHUTDOWN command to send the reply before the server
2580 is shutdown. :) Affected file silcd/command.c.
2582 * Fixed fatal bug in CONNECT command. The hostname was invalid
2583 memory and server crashed. Affected file silcd/command.c.
2585 * Fixed fatal bug in CLOSE command. The server_entry became
2586 invalid but was referenced later in the command. Affected file
2589 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Fixed fatal bug in failure packet handling. Server ignored
2592 the failure and thus crashed when it came.
2596 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2599 that the command may be executed only once in (about) 2 seconds.
2600 The old SILC_CF_LAG flag is same but allows command bursts up
2601 to five before limiting.
2603 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2604 server code. Various commands now includes the CF_LAG_STRICT
2605 flag to disallow any kind of miss-use of the command.
2607 * Fixed the silc_buffer_unformat to not to allocate any data
2608 if the length of the data is zero. It used to allocate the
2609 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2611 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Changed the format of AdminConnection configuration section
2614 in the server. Added username of the admin to the format.
2615 Affected files silcd/serverconfig.[ch].
2617 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2618 to return admin configuration data by host, username and/or
2621 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Implemented WHOWAS command to the server. Added the functions:
2625 silc_server_command_whowas_parse,
2626 silc_server_command_whowas_send_reply,
2627 silc_server_command_whowas_from_client and
2628 silc_server_command_whowas_from_server
2630 * Added <Client ID> argument to the WHOWAS command reply. Updated
2631 the protocol specs accordingly.
2633 * Implemented WHOWAS command and command_reply to the client
2636 Implemented the WHOWAS printing on the user interface.
2638 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * Added new argument to the WHOWAS command reply, the real name.
2641 It is an optional argument. Updated the protocol specs.
2643 * Added SilcIDCacheDestructor callback that is registered when
2644 the SilcIDCache is allocated. The callback is called when
2645 an cache entry in the ID Cache expires, or is purged from the
2646 cache. Added into lib/silccore/idcache.[ch].
2648 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2649 to destruct the client entries when the cache entry expires.
2650 Other ID Cache's in server and in the client library ignores
2653 * If the ID Cache entry's `expire' field is zero then the entry
2654 never expires. Added boolean `expire' argument to the
2655 silc_idcache_add function in the lib/silccore/idcache.[ch].
2656 If it is TRUE the default expiry value is used.
2658 * Added silc_server_free_client_data_timeout that is registered
2659 when client disconnects. By default for 5 minutes we preserve
2660 the client entry for history - for WHOWAS command.
2662 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Added support to the server to enforce that commands are not
2665 executed more than once in 2 seconds. If server receives
2666 commands from client more frequently, timeout is registered
2667 to process the commands. Affected file silcd/command.c.
2668 Added new function silc_server_command_process_timeout.
2670 * Changed NICK_NOTIFY handling in client library to check that
2671 if the client's nickname was changed, so there is no need to
2672 resolve anything from the server.
2674 * Removed error printing from the WHOIS and IDENTIFY commands.
2675 If error occurs then it is ignored silently in the client library.
2676 The application, however, may map the received error to
2677 human readable error string. The application currently maps
2678 the NO_SUCH_NICKNAME error to string.
2680 * Made the command status message public to the application. Moved
2681 them from lib/silcclient/command_reply.c to
2682 lib/silcclient/command_reply.h. The application can map the
2683 received command status to the string with the
2684 silc_client_command_status_message function.
2686 * Added check to the server to check that client's ID is same
2687 as the Source ID in the packet the client sent. They must
2690 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Added dist-bzip hook to the Makefile.am to make bzip2
2693 compressed distributions.
2695 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Server now enforces the maximum length for the nickname and
2698 the channel as protocol specification dictates. 128 bytes for
2699 nickname and 256 bytes for channel name.
2701 * Moved the WHOIS printing to the application. The client libary
2702 does not print out the WHOIS information anymore, the application
2703 must do it. Renamed silc_client_command_reply_whois_print to
2704 the silc_client_command_reply_whois_save.
2706 The client's idle time is also sent to the application now, and
2707 the idle is shown on screen.
2709 * Added silc_client_command_reply_identify_save to save the
2710 received IDENTIFY entries.
2712 * Do not check for channel private keys in message sending and
2713 reception if the channel does not have the PRIVKEY mode set.
2714 Affected file lib/silclient/client_channel.c.
2716 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2718 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2719 just surfaced after chaning the JOIN procedure.
2721 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added silc_client_get_clients_by_list to get client entries
2724 from Client ID list, that is returned for example by JOIN
2725 and USERS command replies. The application should use this
2726 function for example when JOIN command reply is received to
2727 resolve the clients already on the channel (library does not
2728 do that anymore as USERS command reply is not used in the JOIN
2729 procedure anymore). Affected files lib/silcclient/silcapi.h and
2730 lib/silcclient/idlist.c.
2732 * JOIN command reply and USERS command reply returns now SilcBuffer
2733 pointers instead of unsigned char pointers when returning
2734 the client list and mode list.
2736 * Added <Client ID> argument to the JOIN command reply, mainly
2737 for the server to identify for which client the command was
2738 originally sent. Updated protocol specs accordingly.
2740 * Added SilcDlist private_key pointer to the SilcChannelEntry
2741 in the client to support the channel private keys. Affected
2742 file is lib/silcclient/idlist.h.
2744 * Added SilcChannelPrivateKey argument to the function
2745 silc_client_send_channel_message so that application can choose
2746 to use specific private ke if it wants to. If it is not provided,
2747 the normal channel key is used, unless private keys are set.
2748 In this case the first (key that was added first) is used
2749 as the encryption key.
2751 * Implemented the support for channel private key handling.
2752 Implemented the following functions:
2754 silc_client_add_channel_private_key,
2755 silc_client_del_channel_private_keys,
2756 silc_client_del_channel_private_key,
2757 silc_client_list_channel_private_keys and
2758 silc_client_free_channel_private_keys
2760 Affected file lib/silcclient/client_channel.c.
2762 * Added the support for the private keys in the channel message
2763 sending and encryption and in the message reception and
2764 decryption. Affected funtions are
2765 silc_client_send_channel_message and silc_client_channel_message.
2767 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Added SKE's key verify callback to the client library's
2770 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2772 * Removed the statement that server (or router) must send USERS
2773 command reply when joining to the channel so that the client
2774 knows who are on the channel. Instead, the client list and
2775 client's mode list is now sent in the JOIN command reply to the
2776 client who joined channel. This is better solution.
2778 * Added function silc_server_get_users_on_channel and function
2779 silc_server_save_users_on_channel to the silcd/server.[ch].
2781 * Removed function silc_server_command_send_users from the
2784 * Do not show topic on the client library anymore. The topic is
2785 sent in the command reply notify to the application and the
2786 application must show the topic now.
2788 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Added client searching by nickname hash into the IDENTIFY and
2791 WHOIS commands in the server as they were clearly missing from
2792 them. Affected file is silcd/command.c.
2794 * Fixed a bug in private message receiving in the client library.
2795 The remote ID was freed and it wasn't supposed, now it is
2798 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Minor fix to the channel payload; allocate the data area, as it
2801 needs to be of specific length.
2803 * If the key agreement port is zero then the operating
2804 system will define the bound port. Affected files are
2805 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2807 * Added new function silc_channel_payload_decrypt into the file
2808 lib/silccore/silcchannel.[ch].
2810 * Moved the channel message etc, check from silc_packet_decrypt
2811 to applications. The library calls now a generic
2812 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2813 when the packet is either normal or special. This was done to
2814 allow more wide range of checking that was not allowed when
2815 the code was in library. Now applications can do virtually any
2816 checks to the packet and return to the library the decision how
2817 the packet should be processed. Affected files are
2818 lib/silccore/silcpacket.[ch].
2820 Added silc_server_packet_decrypt_check to the server and
2821 silc_client_packet_decrypt_check to the client library.
2823 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2824 to send with specified source and destination information.
2826 * Channel message delivery between routers was broken after the
2827 channel key distribution was fixed earlier. The channel key
2828 was used be to distributed to other routers as well which is not
2829 allowed by the protocol. Now this is fixed and channel keys
2830 really are cell specific and the channel message delivery between
2831 routers comply with the protocol specification.
2833 * Fixed various commands in server to check also the global list
2834 for the channel entry and not just the local list. The affected
2835 file silcd/command.c.
2837 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Added assert()s to buffer formatting and unformatting routines
2840 to assert (if --enable-debug) when error occurs. Affected
2841 file: lib/silcutil/silcbuffmt.c.
2843 * Changed to auto-reconnect to check whether the remote host is
2844 router and register the re-connect timeout if it is. It used
2845 to check that whether we are normal server, but router must do
2846 auto-reconnect with another router as well. Affected file
2849 * Removed the [<key len>] option from CMODE command as the cipher
2850 name decides the key length, nowadays. See the defined ciphers
2851 from the protocol specification.
2853 * Added [<hmac>] option to the CMODE command to define the HMAC
2854 for the channel. Added SILC_CMODE_HMAC channel mode.
2856 * Added [<hmac>] option for the JOIN command so that user can
2857 select which HMAC is used to compute the MACs of the channel
2860 * Added Hmac field to the Channel Message Payload. The integrity
2861 of plaintext channel messages are now protected by computing
2862 MAC of the message and attaching the MAC to the payload. The
2863 MAC is encrypted. Now, it is clear that this causes some
2864 overhead to the size of the packet but rationale for this is that
2865 now the receiver can verify whether the channel message decrypted
2866 correctly and also when private keys are set for the channel the
2867 receiver can decrypt the packet with several keys and check from
2868 the MAC which key decrypted the message correctly.
2870 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2871 lib/silccrypt/silccipher.[ch].
2873 * Added silc_hash_len to return the digest length into the
2874 lib/silcrypt/silchash.[ch].
2876 * Rewrote parts of Silc Channel Payload interface in the
2877 lib/silccore/silcchannel.[ch]. The encode function now also
2878 encrypts the packet and parse function decrypts it.
2880 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2882 * Fixed a minor formatting bug in the SKE's key material processing.
2883 It actually might have processed the keys wrong way resulting
2886 * Redefined the mandatory HMAC algorithms and added new algorithms.
2887 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2888 and hmac-md5 truncated to 96 bits. The mandatory is now
2889 hmac-sha1-96. Rest are optional (including the one that used
2890 to be mandatory). Rationale for this is that the truncated HMAC
2891 length is sufficient from security point of view and can actually
2892 make the attack against the HMAC harder. Also, the truncated
2893 HMAC causes less overhead to the packets. See the RFC2104 for
2896 * Added new [hmac] configuration section. The SKE used to use
2897 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2898 is of course wrong. The official names that must be proposed in
2899 the SKE are the ones defined in the protocol specification
2900 (hmac-sha1-96 for example). The user can configure any hmac
2901 using any hash function configured in the [hash] section. At
2902 least, the mandatory must be configured.
2904 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2906 * Added HMAC list to the SKE proposal list. It has now both
2907 hash algorithm list and HMAC list. This makes the protocol
2908 incompatible with previous versions. The SKE now seems to work
2909 the way it is supposed to work, for the first time actually.
2911 * Defined plain Hash algorithms to the protocol specification.
2914 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Implemented support for key agreement packets into the server.
2917 Added functions silc_server_key_agreement and
2918 silc_server_send_key_agreement. Other than these functions,
2919 server has nothing to do with this packet.
2921 * Added support for private message key packets into the server.
2922 Added functions silc_server_private_message_key and
2923 silc_server_send_private_message_key.
2927 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2928 called in the protocol's final callback instead in the END
2929 protocol state. This makes a little more sense and in the same
2930 time in client we can use the same protocol routines for normal
2931 key exchange and to key agreement packet handling as well.
2933 * Added to both client's and server's KE protocol context the
2934 SilcSKEKeyMaterial pointer to save the key material. We will
2935 bring the key material to the protocol's final callback by doing
2936 this. The final callback must free the key material.
2938 * Added SKE's packet_send callback into client's KE protocol
2939 context so that the caller can choose what packet sending function
2940 is used. This way we can use different packet sending when
2941 doing normal SKE when doing key agreement packet handling (in
2942 the key agreement packet handling we do not want to encrypt
2945 * Implemented the responder side of the key agreement routines
2946 in the client. The client can now bind to specified port and
2947 accept incoming key negotiation. The key material is passed
2948 to the application after the protocol is over.
2950 * Implemented the processing of incoming Key Agreement packet
2951 in the client. Added function silc_client_key_agreement to
2954 * Implemented the intiator side of the key agreement routines
2955 in the client. The client can now initiate key agreement with
2956 another remote client. The key material is passed to the
2957 application after the protocol is over.
2959 * Created client_keyagr.c to include all the key agreement
2962 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2963 SILC_TASK_CALLBACK except that it is not static.
2965 * Created client_notify.c and moved the Notify packet handling
2966 from the client.[ch] into that file.
2968 * Created client_prvmsg.c and moved all private message and
2969 private message key routines from the client.[ch] into that file.
2971 * Create client_channel.c and moved all channel message and
2972 channel private key routines from the client.[ch] into that file.
2974 * Changed silc_client_get_client_by_id_resolve to resolve with
2975 WHOIS command instead of IDENTIFY command, in the file
2976 lib/silclient/idlist.c.
2978 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Implemented the SKE's responder side to the Client library.
2982 * When FAILURE is received to the protocol do not trust it
2983 blindly. Register a timeout to wait whether the remote closes
2984 the connection as it should do it, only after that process the
2985 actual failure. This was changed to both client and server.
2987 * Added client_internal.h to include some of the structures
2988 there instead of client.h in lib/silcclient/.
2990 * Added function silc_task_unregister_by_callback to unregister
2991 timeouts by the callback function.
2993 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Some "Incomplete WHOIS info" errors has been appearing on the
2996 log files. Took away the entry->userinfo check from WHOIS
2997 reply sending. The entry->userinfo is now " " if client did not
2998 provide one. I thought this was fixed earlier but something
2999 is wrong still. Let's see if the error still appears.
3001 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Fixed a minor bug in the login when the channel key is
3004 re-generated in the server. It used to generate the key in
3005 wrong order and thus caused problems in the channel traffic.
3007 * Fixed a minor bug in channel key distsribution after
3008 KICK command. The key was not sent to the router even though
3011 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Added silc_ske_process_key_material_data as generic routine
3014 to process any key material as the SILC protocol dictates. The
3015 function is used by the actual SKE library but can be used by
3016 applications as well. This relates to the private message keys
3017 and the channel private keys since they must be processed the
3018 same way the normal SILC session keys. The protocol dictates
3019 this. Affected files: lib/silcske/silcske.[ch].
3021 Added also silc_ske_free_key_material to free the
3022 SilcSKEKeyMaterial structure.
3024 * Defined silc_cipher_set_key function to set the key for
3025 cipher without using the object's method function. The affected
3026 files: lib/silccrypt/silccipher.[ch].
3028 * Implemented silc silc_client_add_private_message_key,
3029 silc_client_add_private_message_key_ske,
3030 silc_client_del_private_message_key,
3031 silc_client_list_private_message_keys and
3032 silc_client_free_private_message_keys functions in the
3035 Added functions silc_client_send_private_message_key to send
3036 the Private Message Key payload and silc_client_private_message_key
3037 to handle incoming Private Message Key payload.
3039 * Added Cipher field to the Private Message Key payload to set
3040 the cipher to be used. If ignored, the default cipher defined
3041 in the SILC protocol (aes-256-cbc) is used.
3043 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Removed lib/silcclient/ops.h file.
3047 Redefined parts of the SILC Client Library API. Created new
3048 file silcapi.h that deprecates the ops.h file and defines the
3049 published Client Library API. Defined also private message key
3050 API and channel private key API into the file.
3052 This is the file that the application must include from the
3053 SILC Client Library. Other files need not be included by
3054 the application anymore.
3056 * Added new key_agreement client operation callback and also
3057 defined the Key Agreement library API for the application.
3059 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3062 is used by clients to request key negotiation between another
3063 client in the SILC network. If the negotiation is started it
3064 is performed using the SKE protocol. The result of the
3065 negotiation, the secret key material, can be used for example
3066 as private message key.
3068 Implemented the Key Agreement payload into the files
3069 lib/silccore/silauth.[ch].
3071 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Redefined ciphers for the SILC protocol. Added some new ciphers
3074 and defined the key lengths for the algorithms. Changed the
3075 code accordingly. The default key length is now 256 bits.
3077 * Fixed SKE key distribution function silc_ske_process_key_material
3078 when the key length is more than 128 bits. The default key
3079 length in SILC is now 256 bits.
3081 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3082 to indicate unsupported algorithm.
3084 * Renamed rijndael.c to aes.c and all functions as well.
3086 * Fixed a long standing channel key setting bug in client library.
3087 Weird that it has never surfaced before.
3089 * Fixed bug in channel deletion. If the entire channel is removed
3090 then it must also delete the references of the channel entry
3091 from the client's channel list as the client's channel entry and
3092 the channel's client entry share same memory.
3094 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Implemented CONNECT and SHUTDOWN commands in the client.
3098 * Implemented CLOSE command to the client.
3100 * Added the function silc_idlist_find_server_by_name into the
3101 files silcd/idlist.[ch].
3103 Added the function silc_idlist_find_server_by_conn into the
3104 files silcd/idlist.[ch].
3106 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * DIE command was renamed to SHUTDOWN. Updated the both code
3111 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3112 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3114 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3117 * Added function silc_server_create_connection function to create
3118 connection to remote router. My server implementation actually
3119 does not allow router to connect to normal server (it expects
3120 that normal server always initiates the connection to the router)
3121 so the CONNECT command is only good for connecting to another
3124 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3127 or some other client was kicked from the channel.
3129 Implemented the handling of the notify type to both client
3132 Implemented silc_server_send_notify_kicked to send the KICKED
3133 notify. It is used to send it to the server's primary router.
3135 * Implemented the KICK command into server and client.
3137 * Added `query' argument to the silc_idlist_get_client function
3138 to indicate whether to query the client from server or not if
3141 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3142 to indicate that the client is not channel founder.
3146 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Removed the rng context from SilcPacketContext structure and
3149 changed that the packet routine uses the Global RNG API.
3151 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Added support for quit message that client can "leave" on the
3154 channel when it quits the SILC. It is ditributed inside the
3155 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3157 Added silc_server_free_client_data that will take the
3158 signoff message as argument.
3160 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3162 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Updated parts of the protocol specification to keep it up
3167 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3170 payloads in one packet.
3172 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3173 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3174 use now the new List flag.
3176 * Also deprecated the following packet types: REPLACE_ID,
3177 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3179 * Added list support for Notify packet in server.
3181 * Added silc_server_send_notify_channel_change to send the
3182 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3183 the silc_server_send_replace_id.
3185 * Added silc_server_send_notify_nick_change to send the
3186 NICK_CHANGE notify type. Deprecates the function
3187 silc_server_send_replace_id.
3189 * Added silc_server_send_notify_join to send the JOIN notify type.
3190 Deprecates the function silc_server_send_new_channel_user.
3192 * Added silc_server_send_notify_leave to send LEAVE notify type.
3193 Deprecates the function silc_server_send_remove_channel_user.
3195 * Added silc_server_send_notify_cmode and
3196 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3197 types. Deprecates the silc_server_send_set_mode function.
3199 * Added SERVER_SIGNOFF notify type to indicate that server has
3200 quit. This means that all clients on the channel from that
3201 server will drop. This can be also used when netsplit happens.
3203 Deprecated REMOVE_ID packet type since it is not needed anymore
3206 Added silc_server_send_notify_server_signoff to send the
3207 SERVER_SIGNOFF notify type. Deprecates the function
3208 silc_server_send_remove_id.
3210 Added also silc_server_send_notify_signoff to send the
3211 SIGNOFF notify type.
3213 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3214 SILC protocol from this day on. Changed the protocol
3215 specification as well.
3217 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3218 notify type. It is used between routers to notify about
3219 topic changes on a channel.
3221 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3224 * Partly updated the protocol specification to comply with the
3225 changes now made. It is still though a bit outdated.
3227 * The JOIN notify type now takes one extra argument <Channel ID>.
3228 The packet used to be destined to the channel but now the
3229 JOIN type may be sent as list thus it is impossible to
3230 destine it to any specific channel. By adding this argument
3231 it is again possible.
3233 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added CREDITS file. The CHANGES and CREDITS file will appear
3236 in the distribution as well.
3238 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3241 types in the server's silcd/packet_receive.c.
3243 * Implemented CMODE and CUMODE to work in router environment.
3245 * Fixed minor encoding and decoding buglet from the
3246 lib/silccore/silcmode.c.
3248 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3251 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3253 * Changed all SilcConfigServer* and silc_config_server* to
3254 SilcServerConfig* and silc_server_config*, respectively.
3257 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Associated the ID (client or server ID) to the Authentication
3260 Payload to avoid any possibility of forging. Updated the
3261 protocol specification and the code accordingly.
3263 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * The RSA key length is now save to the RsaKey context in the
3266 key generation process in lib/silccrypt/rsa.c. The key length
3267 is now used to figure out the maximum size of the block allowed
3268 to be encrypted/signed.
3270 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3271 is equivalent to the silc_mp_mp2bin but does not allocate any
3274 * Changed silc_mp_mp2bin API to take length argument. If it is
3275 non-zero then the buffer is allocated that large. If zero, then
3276 the size is approximated using silc_mp_sizeinbase, which however
3279 * Created Global RNG API which is global RNG that application can
3280 initialize. After initializing, any routine anywhere in the
3281 code (including library) can use RNG without allocating a new
3282 RNG object. This was done to allow this sort of use of the
3283 RNG in code that has no chance to allocate RNG object. All
3284 applications currently allocate this and many routines in the
3285 library use this. Affected file lib/silccrypt/silcrng.[ch].
3287 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3288 it to use the Global RNG API.
3290 * Defined Authentication Payload into protocol specification that
3291 is used during SILC session to authenticate entities. It is
3292 used for example by client to authenticate itself to the server
3293 to obtain server operator privileges.
3295 Implemented this payload into the lib/silccore/silcauth.[ch].
3296 Implemented also routines for public key based authentication
3297 as the new protocol specification dictates.
3299 Moved definitions of different authentication methods from
3300 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3302 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3303 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3304 silc_pkcs_verify_with_hash functions into the file
3305 lib/silccrypt/silcpkcs.[ch].
3307 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * The client entry's userinfo pointer must be always valid.
3310 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3311 will fail since it requires the userinfo. Now, the userinfo
3312 is allocated as "" if actual userinfo does not exist. Actually,
3313 it must exist and it is totally Ok to drop client connections
3314 that does not announce the userinfo. However, we will make
3315 this workaround for now.
3317 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3318 to return the remote port by socket.
3320 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3323 SILC_SERVER_PENDING_EXEC and added an new macro
3324 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3325 data or when error occurs while processing the pending command.
3327 Added new argument `destructor' into silc_server_command_pending
3328 and to the SilcServerCommandPending object. This destructor is
3329 now called after calling the pending callback or if error occurs
3330 immediately. If error occurs the actual pending callback won't
3331 be called at all - only the destructor. The destructor may be
3332 NULL if destructor is not needed.
3334 All this applies for client library code as well. Similar
3335 changes were made there as well for the pending commands.
3337 In the client, the application must now allocate the
3338 SilcClientCommandContext with the silc_client_command_alloc
3341 * Added reference counter to the SilcServerCommandContext. Added
3342 function silc_server_command_alloc and silc_server_command_dup
3345 Same type of functions added to the client library for the same
3348 * Removed the cmd_ident from IDListData away since it is now
3349 global for all connections. It is the command identifier used
3350 in command sending and with pending commands. The affected file
3353 * Added reference counter to the SilcSocketConnection objecet to
3354 indicate the usage count of the object. The object won't be
3355 freed untill the reference counter hits zero. Currently only
3356 server uses this, and client ignores it. The client must be
3357 set to use this too later. The affected files are
3358 lib/silccore/silcsockconn.[ch]. Added also the function
3359 silc_socket_dup to increase the reference counter.
3361 This was mainly added because it is possible that the socket
3362 is removed underneath of pending command or other async
3363 operation. Now it won't be free'd and proper DISCONNECTING
3364 flags, etc. can be set to avoid sending data to connection that
3365 is not valid anymore.
3367 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3368 the connection. After that it sets SILC_SET_DISCONNECTED.
3369 It is, however, possible that the socket data is not still freed.
3370 The silc_server_packet_process now checks that data is not
3371 read or written to connection that is DISCONNECTED. The socket
3372 get's freed when the reference counter hits zero.
3374 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Changed the client operation API: channel_message operation's
3377 `sender' is now the client entry of the sender, not the nickname
3378 and the `channel' is the channel entry, not the channel name.
3380 In the private_message operation the `sender' is now also the
3381 client entry of the sender not the nickname.
3383 Affected file is lib/silcclient/ops.h and all applications
3384 using the client operations.
3386 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Moved the calling of ops->connect() from connect_to_server_final
3389 into receive_new_id functin since that is the point when the
3390 client is actually allowed to send traffic to network. The
3391 affected file is lib/silcclient/client.c.
3393 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3396 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3397 (if needs broadcasting) instead of broadcasting the packets one
3398 by one which would make a burst in the network traffic.
3400 * Added `broadcast' argument to the functions in silcd/server.[ch]
3401 silc_server_create_new_channel[_with_id] to indicate whether
3402 to send New Channel packet to primary router.
3404 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added new function into the silcd/server.[ch] files:
3407 silc_server_create_new_channel_with_id to create new channel with
3408 already existing Channel ID.
3410 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3411 lib/silccore/silcpacket.h. This packet is used t send list of
3412 Set Mode payloads inside one packet. Server uses this to set
3413 the modes for the channels and clients on those channels, that it
3414 announced to the router when it connected to it. The protocol
3415 specification has been updated accordingly.
3417 * The silc_server_new_channel did not handle the packet coming
3418 from normal server as it normally does not send that. However,
3419 when it announces its channels it does send it. Implemented
3420 the support for that.
3422 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3423 into the file lib/silccore/id.h.
3425 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed memory leaks in the functions silc_idlist_del_client,
3428 silc_idlist_del_channel and silc_idlist_del_server in the file
3429 silcd/idlist.c. All of those leaked like a sieve.
3431 * Fixed some small memory leaks in the client's function
3432 silc_client_notify_by_server.
3434 * Added functions into silcd/server.c: silc_server_announce_clients,
3435 silc_server_announce_channels and silc_server_announce_server.
3436 These functions are used by normal and router server to announce
3437 to its primary router about clients, channels and servers (when
3438 router) that we own. This is done after we've connected to the
3441 These functions effectively implements the following packet types:
3442 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3443 and SILC_PACKET_NEW_ID_LIST.
3445 * Added new functions into the silcd/packet_receive.[ch]:
3446 silc_server_new_id_list, silc_server_new_channel_list and
3447 silc_server_new_channel_user_list to handle the incoming
3448 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3450 * Added support of changing Channel ID in the function
3451 silc_server_replace_id. If the server that announces a channel
3452 to the router already exists in the router (with same name but
3453 with different Channel ID), router is responsible to send
3454 Replace ID packet to the server and force the server to change
3455 the Channel ID to the one router has.
3457 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3458 client that the Channel ID has been changed by the router. The
3459 normal server sends this to the client. Client must start using
3460 the new Channel ID as the channel's ID.
3462 Implemented handling of this new type into lib/silcclient/client.c
3463 into the function silc_client_notify_by_server.
3465 * Added new function silc_idlist_replace_channel_id into the files
3466 silcd/idlist.[ch] to replace the Channel ID.
3468 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Call silc_server_command_identify_check always when processing
3471 the IDENTIFY command in silcd/command.c
3473 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3476 send keepalive packets. The packet can be sent by clients,
3477 servers and routers.
3479 Added function silc_socket_set_heartbeat into the file
3480 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3481 If not set, the heartbeat is not performed. The actual
3482 heartbeat is implemented in the low level socket connection
3483 library. However, application is responsible of actually
3486 Added silc_server_send_heartbeat to send the actual heartbeat
3487 packet into silcd/packet_send.[ch]. Server now performs
3488 keepalive with all connections.
3490 * Added silc_task_get_first function into lib/silcutil/silctask.c
3491 to return the timeout task with shortest timeout. There was a bug
3492 in task unregistration that caused problems. TODO has been
3493 updated to include that task system must be rewritten.
3495 * The client library will now resolve the client information when
3496 receiving JOIN notify from server for client that we know but
3497 have incomplete information.
3499 * Rewrote parts of silc_server_remove_from_channels and
3500 silc_server_remove_from_one_channel as they did not remove the
3501 channel in some circumstances even though they should've.
3503 * Encryption problem encountered in server:
3505 The LEAVE command used to send the Channel Key packet to the
3506 router immediately after generating it. However, the code
3507 had earlier sent Remove Channel user packet but not immediately,
3508 ie. it was put to queue. The order of packets in the router
3509 was that Channel Key packet was first and Remove Channel User
3510 packet was second, even though they were encrypted in the
3511 reverse order. For this reason, MAC check failed. Now, this
3512 is fixed by not sending the Channel Key packet immediately but
3513 putting it to queue. However, this is more fundamental problem:
3514 packets that are in queue should actually not be encrypted
3515 because packets that are sent immediately gets encrypted
3516 actually with wrong IV (and thus MAC check fails). So, packets
3517 that are in queue should be encrypted when they are sent to
3518 the wire and not when they put to the queue.
3520 However, the problem is that the current system has not been
3521 designed to work that way. Instead, the packet is encrypted
3522 as soon as possible and left to the queue. The queue is then
3523 just purged into wire. There won't be any fixes for this
3524 any time soon. So, the current semantic for packet sending
3527 o If you send packet to remote host and do not force the send
3528 (the packet will be in queue) then all subsequent packets to the
3529 same remote host must also be put to the queue. Only after the
3530 queue has been purged is it safe again to force the packet
3533 o If you send all packets immediately then it safe to send
3534 any of subsequent packets through the queue, however, after
3535 the first packet is put to queue then any subsequent packets
3536 must also be put to the queue.
3538 Follow these rules and everything works fine.
3540 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added new function silc_server_remove_clients_by_server to
3543 remove all client entries from ID list when the server connection
3544 is lost. In this case it is also important to invalidate all
3545 client entires as they hold the invalid server entry. This
3546 fixes fatal bug when server has lost connection and will reconnect
3549 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Made some sanity checks to silc_server_daemonise like to check
3552 whether the requested user and group actually exists.
3554 * Added sanity check to SKE's silc_ske_responder_finish to check
3555 that the public and private key actually is valid.
3557 * Invalidate the client's nickname when receiving Replace ID
3558 packet and the Client ID is being replaced. This means that the
3559 server will query the nickname if someone needs it (client)
3562 * Sort the ID Cache in client library when the ID Cache data
3563 has changed (needs sorting).
3565 * Do not allow for SILC client to create several connections to
3566 several servers. The client does not support windows right now
3567 and generating multiple connections causes weird behaviour.
3569 Irssi-silc client does support windows and can handle several
3570 connections without problems, see: www.irssi.org and SILC plugin.
3572 * Fixed some places where client was added to the IDList. The
3573 rule of thumb is following (in order to get everything right):
3574 If the client is directly connected local client then the
3575 `connection' argument must be set and `router' argument must be
3576 NULL to silc_idlist_add_client function. If the client is not
3577 directly connected client then the `router' argument must
3578 bet set and the `connection' argument must be NULL to the
3579 silc_idlist_add_client function.
3581 * The funtion silc_server_packet_send_local_channel actually did
3582 not check whether the client was locally connected or not. It
3583 does that now. Fixed a bug related to LEAVE command.
3585 * Fixed Remove Channel User payload parsing bug in server's
3586 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3588 * The server's silc_server_save_channel_key now checks also the
3589 global ID list for the channel as it might not be in the local
3590 list. Fixed a bug related to LEAVE command.
3592 * Is this the end of the [<unknown>] buglet that has been lurking
3593 around for a long time? A little for loop fix in server's
3594 silc_server_command_whois_parse that is used by both IDENTIFY
3595 and WHOIS command. At least, this was a clear bug and a cause
3596 of one type of [<unknown>] buglet.
3598 * WHOIS and IDENTIFY commands call the function
3599 silc_server_command_[whois/identify]_check function even if
3600 we are not router server.
3602 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Added --with-gmp configuration option. If set the GMP
3605 is always compiled in the SILC source tree. If not set then
3606 it is checked whether the system has the GMP3 installed. If
3607 it has then the GMP won't be compiled (the system's headers
3608 and library is used), if it doesn't have it then the GMP is
3609 compiled in the SILC source tree.
3611 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Changed RSA private exponent generation to what PKCS #1
3614 suggests. We try to find the smallest possible d by doing
3615 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3616 not security fix but optimization.
3618 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Added new config entry [Identity] to fork the server and run
3621 it as specific user and group. A patch from Bostik.
3623 * Imported Dotconf configuration library into lib/dotconf.
3624 This will be used to create the SILC configuration files later.
3625 It will appear in the distsribution after this commit.
3627 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * A big code auditing weekend happening. Auditing code for
3630 obvious mistakes, bugs and errors. Also, removing any code
3633 Removed files for being obsolete:
3635 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3636 inline in the file lib/silcutil/silcbuffer.h)
3638 o lib/silcutil/silcbufutil.c (the header has inline versions)
3640 Changed code to fix possible error conditions:
3642 o The buffer formatting routines now check that the destination
3643 buffer really has enough space to add the data. This applies for
3644 both buffer formatting and unformatting
3645 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3646 unformatting was changed to accomodate following rules:
3647 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3648 sent to the function while XXX_*STRING will not allocate or copy
3649 the data into the buffer. Instead it sets the pointer from the
3650 buffer into the pointer sent as argument (XXX_*STRING used to
3651 require that the pointer must be allocated already). This change
3652 makes this whole thing a bit more consistent and more optimized
3653 (note that the data returned in the unformatting with XXX_*STRING
3654 must not be freed now). The routines return now -1 on error.
3656 o Tried to find all code that use buffer_format and buffer_unformat
3657 and added return value checking to prevent formatting and
3658 especially unformatting errors and possible subsequent fatal
3661 o Changed ske->x and ske->KEY to mallocated pointers in
3662 lib/silcske/silcske.h. Fixed possible data and memory leak.
3664 o Added return value checking to all *_parse* functions. Fixed
3665 many memory leaks as well.
3667 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3668 so that buffer overflows would not happen. All code now also
3669 checks the return value as it can fail.
3671 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Added reconnection support to server if the normal server looses
3674 its connection to the router (for example if router is rebooted).
3675 The server performs normal reconnection strategy implemented
3676 to the server. Affected file silcd/server.c.
3678 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added new packet type SILC_PACKET_SET_MODE that is used to
3681 distribute the information about changed modes (for clients,
3682 channels and clients channel modes) to all routers in the
3683 network. Updated the protocol specification accordingly.
3685 Added functions into silcd/packet_send.c and
3686 silcd/packet_receive.c: silc_server_send_set_mode,
3687 silc_server_set_mode.
3689 Added new files silcmode.[ch] into lib/silccore that implements
3690 the encoding and decoding of Set Mode Payload. Added new type
3691 SilcSetModePayload. Moved the definitions of different modes
3692 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3694 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Oops, a little mistake in server's connection authentication
3697 protocol. The protocol is not ended with FAILURE but with
3698 SUCCESS if the authentication is Ok. :) Affected file is
3701 * Implemented NICK_CHANGE notify handling in server in the file
3702 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3703 the local clients on the channel. After the changing nickname
3704 in router environment snhould work and the [<unknown>] nickname
3705 should appear no more.
3707 The silc_server_replace_id function that receives the Replace ID
3708 payload now sends the NICK_CHANGE notify type also in the file
3709 silcd/packet_receive.c
3711 * Changed WHOIS and IDENTIFY command to support the maximum amount
3712 of arguments defined in protocol specs (3328 arguments). This
3713 fixed a bug that caused problems when there were more than three
3716 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Added extra parameter, command identifier, to the
3719 silc_client_send_command so that explicit command identifier
3722 Changed that ID list routines uses specific command identifier
3723 when sending WHOIS/IDENTIFY requests to the server so that they
3724 can be identified when the reply comes back.
3726 Affected files lib/silcclient/command.[ch],
3727 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3729 * Added `sender' argument to silc_server_packet_send_to_channel
3730 to indicaet the sender who originally sent the packet to us
3731 that we are now re-sending. Ignored if NULL. Affected file
3732 silcd/packet_send.[ch].
3734 * Added some server statistics support in silcd/server_internal.h
3735 SilcServerStatistics structure and around the server code. Also
3736 send some nice statistics information when client is connecting
3739 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Fixed channel ID decoding in server's JOIN command reply in
3742 silcd/command_reply.c
3744 * Fixed braodcasting of replace ID payload to not to send it if
3745 we are standalone server in silcd/packet_receive.c.
3747 * Fixed all channel message sending routines to not to send
3748 packets to clients that has router set, since they are routed
3749 separately in the same function earlier. Affects file
3750 silcd/packet_send.c and all channel packet sending functions.
3752 * In USERS reply, res_argv[i] are not allocated, the table
3753 is allocated. Thus changed that free the table, not its
3756 * In server's whois_check and identify_check if the client is
3757 locally connected do not send any WHOIS commands - they are not
3760 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Fixed some minor bugs in client when sending WHOIS command. The
3763 arguments was in wrong order.
3765 * Removed statis function add_to_channel from server in
3766 silcd/command.c that was previously used with the joining but
3769 * Tested USERS command in router environment successfully with two
3770 routers, two servers and two clients.
3772 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Reorganized the USERS command and command reply in client library
3775 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3776 When the command is given by user we register a pending command
3777 callback that will reprocess the command after the reply has been
3778 received from the server. When reprocessing the packet we then
3779 display the information. Thus, the USERS information is displayed
3780 now in the command callback instead of in the command reply
3781 callback. The processing of the command is same as previously
3782 when server has sent the command reply in the JOINing process.
3784 * Added to USERS command in silcd/command_reply.c to join the client,
3785 we didn't use to know about, to the channel after we've created
3786 a client entry for it. Also, for clienet we did know already still
3787 check whether it is on the channel or not and add it if not.
3789 * Removed silc_server_command_join_notify as the function and its
3792 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Changed the client's pending command handling to the same as the
3795 server's pending command handling. It is also now possible to
3796 execute command reply functions from other command reply
3797 function as the function callbacks for commands and command
3798 replies are one and same. The pending commands are not static
3799 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3800 in client connection context. Thus, pending commands are server
3801 connection specific as it is convenient.
3803 Changed the function silc_client_command_pending and
3804 silc_client_command_pending_del and added new function
3805 silc_client_command_pending_check. Removed the
3806 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3809 * Added cmd_ident, current command identifier, to the client
3810 connection context in lib/silcclient/client.h to keep track on
3811 command identifiers used in command sending. Client's command reply
3812 function handling now supports the mandatory command identifiers.
3814 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3815 funtions in client to fully support pending command callbacks.
3817 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3818 as one of the arguments to the application in the command reply
3821 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3822 before first releasing SILC but came back. Now it is removed again
3823 and should come back nomore. The FORWARDED flag was used only
3824 by the JOINing procedure by forwarding the command packet to router.
3825 Now, the JOINing procedure has been changed to more generic (due
3826 to various router environment issues) and FORWARDED is not needed
3827 anymore for anything. The protocol specification is yet to be
3830 Now, removed silc_server_packet_forward from server and the flag
3831 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3833 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * Renamed NAMES command to USERS command. The NAMES was named that
3836 due to historical reasons. Now it is renamed. Also, rewrote
3837 parts of the USERS command. The nickname list is not sent anymore
3838 by the server. Only Client ID and mode lists are sent in the USERS
3839 command. Changed this also to the protocol specification.
3841 The client now resolves the names and stuff after it receives
3842 the USERS list from the server when joining to the channel.
3844 * WHOIS and IDENTIFY commands has been changed to support multiple
3845 Client ID's per command. One can now search for multiple users
3846 in the network by sending only one WHOIS or IDENTIFY command.
3847 Changed the code and the protocol specifications.
3849 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3850 uses silc_server_command_whois_parse to parse the request. */
3852 * If normal server, do not parse the WHOIS and IDENTIFY requests
3853 before sending it to the router. Saves some time.
3855 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Fixed JOIN command on client library. Wrong number of arguments
3858 used to crash the client.
3860 * Added silc_server_channel_has_global function to check whether
3861 channel has global users or not.
3863 * Added silc_server_channel_has_local function to check whether channel
3864 has locally connected clients on the channel.
3866 * The silc_server_remove_from_one_channel now checks whether the
3867 channel has global users or not after given client was removed from
3868 the channel. It also checks whether the channel has local clients
3869 on the channel anymore. If it does not have then the channel entry
3870 is removed as it is not needed anymore.
3872 * The silc_server_notify now checks on JOIN notify whether the joining
3873 client is one of locally connected or global. If it is global then
3874 the channel has now global users on the channel and that is marked
3875 to the channel entry. Also, it now saves the global client to
3876 global list who is joining and JOINs it to the channel. This is
3877 for normal server, that is.
3879 Changed silc_server_send_notify_on_channel,
3880 silc_server_packet_relay_to_channel and
3881 silc_server_packet_send_to_channel check if we are normal server
3882 and client has router set (ie. global client) do not send the
3883 message to that client, as it is already routed to our router.
3885 * Implemented LEAVE notify type handling in silc_server_notify
3888 * Tested LEAVE command in router environment successfully. Tested
3889 with two routers, two servers and two clients.
3893 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3895 * Implemented SIGNOFF notify type handling in silc_server_notify
3898 * silc_server_remove_id now removes the client entry from all channels
3899 it has joined and thusly sends SIGNOFF notify type.
3901 * Rewrote the NAMES list generation in server by removing two excess
3902 loops. The lists are created now inside one loop.
3904 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * silc_server_remove_channel_user checks now also global list
3907 for channel and client.
3909 * silc_server_new_channel_user checks now both local and global
3910 list for channel and client. Fixed a bug in client id decoding.
3911 Used to decode wrong buffer.
3913 * silc_server_channel_message checks now both local and global
3914 list for channel entry.
3916 * Tested channel joining (hence JOIN) in router environment
3917 successfully. Tested with two routers, two servers and two
3920 * Tested channel message sending in router environment successfully.
3922 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Added silc_server_save_channel_key into server.[ch] to save the
3925 received channel key in Channel Key payload processing. It is
3926 also used in JOIN command reply handling.
3928 Equivalent function silc_client_save_channel_key added into
3929 client.[ch] into client library.
3931 * Changed JOIN command reply to send information whether the channel
3932 was created or not (is existing already) and the channel key
3933 payload. Changed protocol specs accordingly.
3935 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3936 the request was sent by ID and not by nickname. Crashed on
3939 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3942 now correctly save the received data.
3944 * silc_server_free_sock_user_data now notifies routers in the
3945 network about entities leaving the network.
3947 At the same time implemented functions silc_server_remove_id
3948 and silc_server_send_remove_id to receive and send REMOVE_ID
3949 packets. The packet is used to notify routers in the network
3950 about leaving entities. The ID removed will become invalid in
3953 * Added function silc_idlist_del_server into server. Removes and
3954 free's server entry from ID list.
3956 * silc_server_private_message function now checks, if we are router,
3957 that the destination ID really is valid ID, naturally.
3959 * In router when NEW_ID packet is received (for new client) the
3960 hash of the Client ID is saved in the ID Cache but the
3961 client->nickname is set to NULL, instead of putting the hash
3964 IDENTIFY command now also checks that client->nickname must be
3965 valid. If it is not if will request the data from the server who
3966 owns the client. Added new function
3967 silc_server_command_identify_check.
3969 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3970 to set the command to already allocated Command Payload.
3972 * Tested private message sending in router environment with two
3973 routers, two servers and two clients. Fixed minor bugs and now
3976 * Fixed segfault from client's NAMES command. Used to crash if
3979 * Forwarded packets must not be routed even if it is not destined
3980 to the receiver. Changed server code comply with this.
3982 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Added `require_reverse_mapping' boolean value to ServerParams
3985 structure. If TRUE (not default) the server will require that
3986 the connecting host has fully qualified domain name.
3988 If the reverse mapping is not required and hostname could not be
3989 found the IP address is used as hostname.
3991 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Implemented version string checking to both client and server.
3994 The check is incomplete currently due to the abnormal version
3995 strings used in development version of SILC.
3997 * Changed all command functions in server to use the new
4000 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Changed char *data to unsigned char *data in ID Cache system to
4003 support binary data as ID Cache data. Changed code to support
4004 binary data in lib/silccore/idcache.c.
4006 * Renamed silc_server_packet_relay_command_reply to
4007 silc_server_command_reply as it is normal packet receiving
4008 function. Rewrote the function to accept command replys for
4009 servers and not only for clients.
4011 * Mark remote router always as registered server if we are connecting
4012 to it. Otherwise, commands sent by the router to us are ignored.
4014 * All ID List find routines now returns the ID Cache Entry pointer
4015 as well if requested.
4017 * WHOIS command works now in router environment, tested with two
4018 routers, two servers and two clients.
4020 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4021 in router environment (as it is almost equivalent to WHOIS) but
4022 hasn't been tested thoroughly. Added new functions:
4024 silc_server_command_identify_parse
4025 silc_server_command_identify_send_reply
4026 silc_server_command_identify_from_client
4027 silc_server_command_identify_from_server
4029 * Disabled route cache adding because adding two different ID's with
4030 same IP replaces the old cache entry thus giving wrong route.
4031 The entry->router->connection is always the fastest route anyway
4032 so route cache may not be needed. Of course, new routes maybe
4033 established after receiving the ID when the entry->router->connection
4034 might not be anymore the most optimal.
4036 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Add route cache for received ID for fast routing.
4040 * Added silc_server_packet_route to route received packet on router
4041 that is not destined to us.
4043 * Renamed silc_server_get_route to silc_server_route_get.
4045 * Added id_string and id_string_len fields into SilcServer to
4046 include encoded ServerID for fast comparing without excess
4047 encoding of the ID's.
4049 * Cleaned up WHOIS command on server side. Added following static
4052 silc_server_command_whois_parse
4053 silc_server_command_whois_check
4054 silc_server_command_whois_send_reply
4055 silc_server_command_whois_from_client
4056 silc_server_command_whois_from_server
4058 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4059 arguments in command replies. All command functions should be
4060 updated to use this macro.
4062 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Minor typo fixes on command reply handling on server.
4066 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added silc_server_command_add_to_channel internal routine to add
4069 the client to the channel after router has created the channel and
4070 sent command reply to the server.
4072 * Added generic silc_server_send_command to send any command from
4075 * Use static buffer with ID rendering instead of duplicating data.
4077 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed a channel user mode bug when joining to a channel server gave
4080 everybody channel founder rights, oops.
4082 * We mark ourselves as the router of the incoming server connection
4083 if we are router ourselves. This way we can check in some packet
4084 sending functions whether it is locally connected server. For
4085 incoming router connections we put NULL.
4087 * For router sending packets locally means now always sending the
4088 packet cell wide; to local clients and local servers. For normal
4089 server sending packet locally means sending it to only local
4092 * Fixed the JOIN command to really work in router environment. If the
4093 channel is created it is always created by the router. Router is
4094 also responsible of making the initial joining to the channel,
4095 sending JOIN notify to the sending server and distributing
4096 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4097 does not exist server doesn't do anything else but forward the
4098 command to the router which performs everything.
4100 * Added silc_server_send_channel_key function to send the Channel Key
4103 * Added silc_server_create_channel_key to create new channel key. The
4104 channel key is now re-generated everytime someone joins or leaves
4105 a channel, as protocol dictates. Note: channel->key_len is the
4108 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4111 packet_receive.[ch] to separate packet sending and receiving
4112 routines. The server.[ch] now includes everything else including
4113 actual packet processing (writing and reading data) and other
4116 Renamed silc_server_private_message_send_internal to
4117 silc_server_send_private_message. The routine is still though
4118 used only to relay private messages as server does not send
4119 private messages itself.
4121 Renamed silc_server_new_channel to silc_server_create_new_channel
4122 and added new function sicl_server_new_channel that handles the
4123 incoming New Channel packet. Added also new sending function
4124 silc_server_send_new_channel to send New Channel Payload.
4126 * Added new function silc_server_notify to process incoming notify
4127 packet to the server/router. Server may then relay the notify
4128 to clients if needed.
4130 * Added new function silc_server_new_channel_user to process incoming
4131 New Channel User packet. Router will redistribute the packet and
4132 send JOIN notify to its local clients and locally connected servers
4133 if needed. Normal server will send JOIN notify to its local client
4134 on same channel when received this packet. Added also corresponding
4135 sending function silc_server_send_new_channel_user to sent the
4138 * Added boolean route argument to send_notif_to_channel and
4139 packet_send_to_channel functions to attempt to route the packet
4140 if it is TRUE and send only locally if it is FALSE.
4142 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * silc_server_replace_id now broadcasts the received replace ID
4145 packet if it is not broadcast packet already. The router must
4146 broadcast to inform other routers about changed ID.
4148 * Added backpointer to server's router into SilcServer context in
4149 silcd/server_internal.h.
4151 * Fixed silc_server_packet_broadcast to send correct broadcast
4154 * The channel key is now distributed to the local client as soon
4155 as it is received from the router (in router environment) so that
4156 no other packet may be sent for the channel until client has
4159 * silc_server_remove_channel_user now broadcasts the received
4160 Remove Channel User packet if it is not broadcast packet already.
4161 The router must broadcast to inform other routers about removed
4164 * Added users field into SilcPacketContext that is a reference count
4165 of the context. One can increase the reference count by calling
4166 silc_packet_context_dup which is now changed to just increase the
4167 reference count instead of duplicating the data. The reference
4168 count is decresed by calling silc_packet_context_free that will
4169 free the data after the reference count hits zero.
4171 For now on the packet context and everything allocated into it
4172 (including the raw packet from network) must be freed by calling
4173 the new silc_packet_context_free function. Added also new function
4174 silc_packet_context_alloc that must be used now to allocate the
4175 context. This also means that if a routine is asynchronous from
4176 silc_[client/server]_packet_parse_type the packet context must
4177 be duplicated by calling silc_packet_context_dup. Otherwise it
4178 gets free'd after silc_[client/server]_packet_parse_type returns.
4179 Also, one must remember that if packet is duplicated then its
4180 reference count must be decresed by calling the free function as
4181 many times as it was duplicated.
4183 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4184 from both client and server.
4186 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Made joining to a channel working in router environment.
4190 * Cleaned up JOIN command on server side and create function
4191 silc_server_command_join_channel internal routine to make the
4194 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Changed silc_command_pending list to SilcDList. Also, added
4197 `ident' field to SilcServerCommandPending structure to identify
4198 the reply and to call correct callback.
4200 Added silc_server_command_pending_check function to replace the
4201 corresnponding macro. The silc_command_pending list is not
4204 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4205 to set identifier to previously allocated Command Payload. It
4206 is used to set identifier for command when resending Command
4209 * Added silc_command_payload_encode_payload to encode Command
4210 Payload buffer from SilcCommandPayload structure.
4212 * Added silc_argument_payload_encode_payload to encode Argument
4213 payload buffer from SilcArgumentPayload structure.
4215 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Changed WHOIS command to support router connection on server side.
4218 The whois request is always sent to router unless the server is
4219 standalone server. After server has received the reply from the
4220 router will it send the reply to the client.
4222 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4223 broadcast received broadcast packet. The function is used only
4224 by router. The broadcast packet is always sent to the router's
4227 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4228 render given ID to printable string, for log files for example.
4230 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Made basic router to router connections working. At least they
4233 can now connect to each other but nothing really works the way
4234 they are supposed - yet.
4236 * Added new initiator token to RouterConnection configuration
4237 file in silcd/serverconfig.[ch]. It is used to tell whether we
4238 are the initiator to the remote router or whether we'll expect
4239 the other end to connect.
4241 * Moved registering of listener task to silc_server_init, hence
4242 the server starts listenning as soon as it is run, even if it
4243 does not have connections to other routers. Let's see how well
4246 * Changed default connection retry timeouts for more suitable in
4249 * Removed cipher and such arguments from silc_idlist_add_client
4250 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4251 Added new function silc_idlist_add_data to add the keys and stuff
4254 * Added SilcIDListData structure and added it to SilcClientEntry
4255 and SilcServerEntry as their first field in the structure. This
4256 way we can explicitly cast the ID entries to the SilcIDListData
4257 structure and get common data for the entries. In past, we had
4258 to first check what type of connection it is and then cast it to
4259 correct ID entry type. Now, we can directly cast the opaque
4260 pointer to the SilcIDListData (no matter what ID entry it actually
4261 is) and get the data needed.
4263 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4266 in some circumstances even if threre were timeout tasks, though not
4267 IO tasks, but tasks anyway. Now fixed.
4269 * Defined SilcServerConnection structure to hold connection specific
4270 stuff about directly connected servers and routers. The definition
4271 is currently in silcd/server_internal.h. I thought about having
4272 a bit more important role fro this struct but for now it is used
4273 only when connecting to other server (or router actually).
4275 * Added connecting retry support in server when connecting to
4276 router(s). The retry feature implement exponential backoff
4277 algorithm. Also, added SilcServerParams structure to hold default
4278 parameters for server. For now, it include these retry settings
4279 and are hard coded. After server is moded to be as Silc Server
4280 Library this structure will be more important.
4282 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Changed client librarys channel->clients table to SilcList and
4285 changed code accordingly.
4287 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Changed client's channel table to SilcList and changed code
4290 accordingly. Also changed SilcChannelClientEntry to include back-
4291 pointer to the channel so that client entry can use that structure
4292 as list as well and we have fast cross-reference to the channel.
4293 This change dramatically decreased the complexity of channel
4294 handling with client entry and vice versa (removed one extra
4295 loop when searching for channel entry from many functions).
4297 * Changed server->sim from table to SilcDList and changed code
4300 * NAMES command can now be used from user interface. It will show
4301 the user list on the channel, neatly.
4303 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4304 Code now saves realname of the user if it becomes available.
4306 * Renamed configure.in to configure.in.pre and made ./prepare
4307 script to automatically add correct version string to
4308 configure.in which it creates from configure.in.pre.
4310 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * NAMES command reply now shows users mode with the nickname when
4315 * Moved silc_client_ch[u]mode[_char] functions from
4316 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4317 place sucks, they are utility functions and should be in some
4320 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4322 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4325 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Added TRQ (efficient deque and list library) into lib/trq. This is
4330 a very good list library that is currently used in the SILC. Defined
4331 SilcList API over the library because I didn't like the API very
4332 much. See lib/trq/silclist.h for the API and examples of how to
4333 use the API. Fixed various places in the code to use the new
4334 SilcList API. The SilcList is meant for lists that has a structure
4335 already defined as a list. It is not suitable to add just some
4336 context to the list (in TRQ, the context is the list actually).
4338 So, I defined SilcDList that can be used for the purpose where
4339 predefined list structure does not exit. This can be used as
4340 such list. Now some context just can be added to the SilcDList.
4341 Currently this list is not used in the SILC just yet, though there
4342 are a lot places where this can replace dynamically allocated
4343 tables and I will fix these places, later, to use SilcDList.
4344 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4345 and use TRQ internally).
4347 Also fixed some annoying warning messages that the original TRQ
4348 code generated. Also minor changes to TRQ's Makefile.in.
4350 * Added support for querying by Client ID to both WHOIS and
4351 IDENTIFY commands into server, as required by the protocol.
4353 * Removed method function pointers from SilcBuffer structure. They
4354 weren't used to anything and just increased the context size for
4355 no good reason. This change also made silc_buffer_alloc and
4356 silc_buffer_free functions inline functions.
4358 * Disabled command flooding detection support until it's fixed so
4359 that it accepts commands in but does not execute them more than once
4362 * Added silc_net_localhost(), to return local hostname, into
4363 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4364 that must be initialized before calling silc_client_init.
4366 * Added new function: silc_server_send_notify_on_channels to send
4367 notify messages to all channels client has joined. It is assured
4368 that the message is sent only once per client.
4370 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4371 lib/silcutil/silcutil.[ch] as silc_format function. The new
4372 function is generic and is used by server as well, not only by
4373 the logging routines.
4375 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4376 the provided version string was not acceptable. Added new function:
4377 silc_ske_check_version into lib/silcske/silcske.h. The function
4378 must be implemented by the application (client or server) and it
4379 does not reside in the SKE library. The function checks the version
4380 string remote end sent.
4382 * Added back pointers (to opaque context and to SilcSocketConnection)
4383 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4385 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4386 duplicate packet context structure.
4388 * Changed `notify' client operation to send same arguments as client
4389 receives from server except for ID's. ID's are mapped to correct
4390 ID entry and that is returned. Also, if channel entry is not sent
4391 by server but the notify is for channel the channel entry is sent
4392 to application (otherwise application doesn't know that it is for
4393 channel (library gets it from packet's Destination ID)).
4395 * Added silc_client_remove_from_channels into client library to
4396 remove a client from all channels it has joined to. Used when
4397 received SIGNOFF notify from server. Added also new function
4398 silc_client_replace_from_channels to replace old ID entry with
4399 new ID entry on all channels. Used when received NICK_CHANGE
4402 * Fixed ID Cache list handling in silc_idlist_get_client in
4403 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4404 to get (or query) client by ID.
4406 * Updated TODO list.
4408 * Added connection authentication status message defined by the
4409 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4410 support for these into the code in client and server side.
4412 * Added generic function silc_client_send_command to send any command
4413 with variable argument list. Application should use this function
4414 to send commands if the command functions provided by the library
4415 does not suite for the application's user interface needs.
4417 * Added new `failure' client operation. Application is notified about
4418 received failure packet if client is executing a protocol. In this
4419 case the protocol's execution has failed.
4421 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4422 is required by the protocol.
4424 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4425 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4428 * Added status flag to SilcSKE object to indicate realtime status
4429 of the SKE protocol.
4431 * Application receives now exactly same command reply arguments as
4432 the library receives from server. However, if ID is received the
4433 corresponding ID entry is returned to the application (eg. Client
4434 ID is mapped to correct SilcClientEntry entry and that is returned).
4435 Changed command_reply client operation due to this change.
4437 * Changed all ID's in commands and in command replys as ID Payloads.
4438 Change affected both client and server side codes.
4440 All ID's sent in SILC network (with execption of ID's in SILC
4441 Packet header) are sent in ID Payload to support variable length
4444 * Server now notifies nick changes and notifies all clients on
4445 the channels about the new nickname (about the new Client ID,
4448 * Implemented CMODE command to change channel modes. Supports all
4449 channel modes defined by the protocol specs except ban and invite
4450 lists. (Also, private channel key mode is supported but support for
4451 setting private channel key in client is missing, thus, this mode
4452 has no effect on client side (except that server requires that the
4453 client uses private channel key and normal channel traffic does not
4456 Also, invite mode works per se, but INVITE command does not work
4457 yet correctly, so you can set channel as invite only channel but
4458 inviting clients to the channel does not work (it is yet to be
4459 thought what's the best way to do it).
4461 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4462 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4463 Implemented CUMODE command to change user's mode on the channel.
4464 Supports all modes defined by the protocol specs.
4466 * Added NAMES command reply to return users modes on the channel.
4468 * Removed unnecessary and slow ciphers from lib/silccrypt.
4470 * Set SO_KEEPALIVE option to connection sockets by default.
4472 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4474 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4475 redefined the Notify Payload into protocol specs.
4477 * Added silc_id_payload_parse_id to get ID directly from raw
4480 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4483 accept searching by Client ID as well.
4485 * Added support for LEAVE and SIGNOFF notify types in client library.
4487 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4488 to parse ID Payload from raw data.
4490 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Added flags parameter into silc_ske_assemble_security_properties
4493 function in lib/silcske/silcske.[ch].
4495 * Changed notify client operation to fit better for notify messages
4496 sent by server. The notify payload received from server is now
4497 passed to the application (after parsing it to SilcNotifyPayload).
4498 It is application's responsibility to retrieve the arguments
4499 from the payload and show the message the way it wants. The message
4500 sent by server is implementation specific.
4502 * Changed public keys to comply with the protocol specification.
4503 Old public keys are not supported anymore and are not compatible.
4505 * Removed nickname from Channel Payload as the latest draft removed
4506 it. The client must resolve the nickname from the NAMES command
4507 reply received when it joined the channel.
4509 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4511 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Fixed some errors in protocol specification drafts.
4515 * Created lib/silccore/silcnotify.c to implement Notify Payload
4516 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4517 generic payloads described by protocol specifications. The file
4518 includes implementations for ID Payload and Argument Payload.
4520 * Changed Command Payload implementation to use the new Argument
4521 Payload. Changed command_xxxx_payload to command_payload_xxxx
4522 to comply with SILC coding conventions.
4524 * Added suppport for Argument Payload handling in Notify Payload
4525 implementation as protocol requires it. Added the new support
4526 into server and client lib as well.
4528 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Added support for multiple nicknames on same channel. [n] is
4531 added locally to the nickname if there are more than one same
4532 nicknames on the channel.
4534 * Server now sends all nicknames that matched WHOIS request.
4535 Client also shows the list received from server.
4537 * Added TOPIC command to client side. User can now set and show
4538 current topic on channel.
4540 * Added MOTD command to client and server. Also, server sends the
4541 motd when client connects to the server.
4543 * Changed version strings to comply ISO 8601.
4545 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Fixed protocol error handling in client library. It should now
4548 cope even if the SKE fails for some reason.
4550 * Made new protocol specification drafts for submitting to IETF.
4552 * Implemented TOPIC command to server in silcd/command.c.
4554 * Added two new notify types into lib/silccore/silcnotify.h:
4555 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4556 notify nickname change and topic setting/change on a channel.
4558 * API change of command_reply operation in client library. The
4559 application gets now the status type received from server as well.
4561 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4565 * Cras fixed and optimized the packet handling even further and
4566 it should work now. Minor change to the prototype of function
4567 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4569 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added new function into lib/silcutil/silcschedule.[ch]:
4572 silc_schedule_with_fd to select() a specified fd. The function
4573 returns after timeout expires or data arrives or goes. The
4574 function is used by packet routines to wait that all data is
4575 received from network.
4577 * Fixed data reading from network in lib/silccore/silcpacket.c.
4578 The code now assures that all data is read from the fd and then
4579 continues packet processing. This was a bug fix since the code
4580 used to drop some data in some circumstances.
4582 * Added new function into lib/silcclient/client.[ch]:
4583 silc_client_start_key_exchange to start key exchange after
4584 connection has been established to server. The code internally
4585 now uses this funtion but its main purpose was to provide it
4586 for applications that perform their own connecting. After
4587 application has created a connection it merely calls this
4588 function to start the key exchange between client and server.
4589 The library takes care of everything else after that.
4591 Updated also lib/silcclient/README to explain the usage of
4594 * Do not send to application information that connection has
4595 been established. Application gets notified it by connect
4598 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Applied cras's patch to add silc_schedule_one function. The
4601 function runs scheduler once and returns.
4603 * Fixed the scheduler after cras messed it up. The timeout
4604 handling works now as it's supposed to work.
4606 * Added into lib/silccore/ silcnotify.h to include notify
4607 message types support. Changed silc_server_send_notify*
4608 functions, in server.[ch], to support those new notify types.
4609 Added the support for the notify types into client library,
4610 as well. Added new notify client operation into ops.h in
4613 * Changed silc_server_packet_send_to_channel to send normal
4614 packets instead of just channel message packets. The function
4615 is now used to send the notify packets to channels. It is not
4616 used to send channel message packets anymore, as server never
4619 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4620 va_arg()s as it seems to require it nowadays. I guess, if SILC
4621 is compiled with older va_arg() the new code should work anyway.
4623 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Splitted core library. Core library (lib/silccore) includes
4626 now only SILC protocol specific core (and common) components.
4627 Created new utility library (lib/silcutil) that includes more
4628 generic purpose stuff. The stuff for util library was taken
4629 from the old core library. This was minor and easy split.
4631 * Created SILC Client Library (lib/silcclient) that includes
4632 implementation of the SILC client without user interface. This
4633 was major move from silc/ directory. The code has been changed
4634 so that it is transparent towards the user interface. The
4635 silc/ directory includes now the same user interface as before
4636 and it uses the new client library. Read lib/silcclient/README.
4637 Basicly, the client library performs everything else related
4638 to SILC except user interface handling. Also, configuration
4639 files are considered to be part of user interface and library
4640 does not handle them.
4642 This change also changed a lot of structures, function naming etc.
4643 Most important change was that SilcClientWindow object was
4644 renamed to SilcClientConnection in the client library. Created
4645 also new file lib/silcclient/ops.h. Also added new files
4646 silc/local_command.[ch] and silc/client_ops.[ch].
4648 All these changes were made to make it easier for user interface
4649 designers to create what ever user interface for the SILC client
4652 It is also expected that the server will be moved to lib
4653 directory as well and SILC Server Library will be created;
4654 sometimes in the future.
4656 * Removed Local commands from lib/silccore/silccommand.h as
4657 they are application specific and new client library does not
4658 handle any of those anymore.
4660 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4661 old client implementation in silc/.
4663 * Added support for callback functions in SILC_LOG_* macros.
4664 Application can now set its own callbacks that will be called
4665 instead of using the default functions that will always print
4666 the debug messages to stderr (or stdout). Also, debugging can
4667 now be disabled by setting silc_debug to FALSE and re-enabled by
4668 setting it to TRUE. Note, that logging will still work even
4669 if debugging is disabled.
4671 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4672 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4673 silc_log_reset_debug_callbacks.
4675 * To enable debugging in silc client one must give now -d
4676 option on command line.
4678 * Changed silc_schedule_init to automatically allocate task queues
4679 if they are not allocated before calling it.
4681 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added GMP 3.1 into math library.
4685 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4688 a channel in SILC network. The packet is used by servers and
4689 routers to notify other routers that user has left a channel.
4690 This little feature was missing until now. Added the feature
4691 to protocol specification as well.
4693 Added functions: silc_server_send_remove_channel_user and
4694 silc_server_remove_channel_user into server.[ch].
4696 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4697 lib/silccore/silcpacket.h. However, they are not implemented
4700 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed joining to a channel and sending channel messages
4703 between server and router. The channel message sending should
4704 now work inside a cell.
4706 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Fixed the private message sending between server and router.
4709 The private message sending should now work inside a cell.
4711 * Added silc_server_replace_id into server.[ch] to replace
4712 existing ID in the SILC network.
4714 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4715 and silc_idlist_replace_server_id into idlist.[ch] in server.
4717 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Fixed the server to server connections. Server can again now
4720 connect to router. Router to router connections probably does
4723 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Added dynamic protocol registering support. Now protocols can
4726 registered and unregistered on the fly. Patch by cras.
4728 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Added lib/contrib directory to hold routines that some platforms
4731 don't have but are needed by SILC.
4733 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4734 into lin/contrib to provide getopt() and getopt_long() for
4735 those who don't have it.
4737 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Added AWAY command to client. When away message is set and
4740 client receives a private message packet the client automatically
4741 replies to the sender with the away message.
4743 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4744 bug seemed to be the cause of recent problems when compiling
4747 * Added version detection support to SKE protocol specification
4748 and added the new changes to the SKE implementation as well.
4749 There were other minor changes in the SKE protocol as well.
4751 Many changes in lib/silcske/silcske.[ch] and in
4752 lib/silcske/payload.[ch].
4754 * Added ^U functionality, clear input line. Patch from cras.
4756 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Mainly small bugfixes on core library. Fixed some debugging
4759 logging and buffer overflow in silclog.c.
4761 * Updated config.sub and config.guess on the distribution tree.
4763 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Added command lagging support in server. Client may execute
4766 commands now only once in two seconds.
4768 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Optimized packet reception. MAC computation and checking is now
4771 also more optimized. A lot previously duplicated code is now
4772 used as generic by both client and server.
4774 * Fixed key pair generation in clientutil.c
4776 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4778 * Added into lib/silccore/silcbufutil.[ch] new function;
4779 silc_buffer_realloc.
4781 * Moved generic packet sending/encryption functions to
4782 lib/silccore/silcpacket.[ch] from client and server. Some
4783 rewriting of the functions.
4785 * Moved all generic packet reception/decryption functions to
4786 lib/silccore/silcpacket.[ch] from client and server. The
4787 packet processing is now much cleaner in both client and server.
4788 These were major changes in both client and server.
4790 * Created many common functions in server to do packet sending.
4791 Previously code were duplicated a lot, this has been removed
4794 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Rewrote major parts of the ID cache system. Don't know
4797 whether it is better now or not but at least the API is more
4800 * Major rewrite on ID cache stuff on client because of the ID
4801 cache API changes. Added idlist.c to client.
4803 * Also major rewrite on ID cache stuff on server as well.
4804 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4805 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4806 in hand, instead they are all put into the ID cache system now.
4807 All server_idlist_* routines uses ID cache now instead of
4808 traversing its own lists (those lists does not exist anymore).
4809 SilcIDList though still exists. Also, SilcXXXEntry's are
4812 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Finally made the SKE implementation compliant to the protocol
4815 specification. All mp integers are now binary encoded as
4816 opposed being HEX encoded.
4818 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4821 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4822 functions: silc_[encode/decode]_pem. Also added function
4823 silc_encode_pem_file to PEM encode with newlines ('\n') for
4826 * SILC public keys are now encoded either PEM or binary. Same
4827 option is for private keys as well. By default private keys
4828 are binary encoded and public keys PEM encoded. Silly HEX
4829 encoding were removed.
4831 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4832 function to create fingerprints.
4834 * Fixed a bug in SHA1; does not change the original data anymore.
4836 * Partly implemented INFO command on client and server side.
4837 Fixed CLEAR command. Changes to SERVER command; show current
4838 server(s) when giving command without arguments. Added
4839 VERSION command to client.
4841 * Added check to server that unregistered connections cannot
4842 execute commands (unless it is specificly allowed).
4844 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Fixed screen refresh.
4848 * Fixed channel joining bug from client. On some circumstances
4849 client tried to join to a channel it had already joined.
4851 * Added public key verification process into client's protocol.c.
4852 The client now verifies the public key from user and saves
4853 it into ~./silc/serverkeys/ directory.
4855 Added into: clientutil.[ch]: silc_client_verify_server_key.
4857 * Changed SKE protocol's silc_ske_initiator_finish function
4858 to accept callback function that verifies the received public
4859 key. Removed old silc_ske_verify_public_key function.
4861 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4864 silc_pkcs_private_key[_data]_set.
4866 * Made the password and public authentication more cleaner in
4867 server's protocol.c.
4869 * Removed historic and obsolete protocol `channel_auth' from
4870 both client and server.
4872 * Removed wrong way of sending command status messages from
4873 server to client in server's command.c. The old way violated
4874 protocol specification.
4876 Changes to silccore/silccommand.[ch]: removed
4877 silc_command_encode_status_payload -> not needed anymore,
4878 changed silc_command_encode_payload_va to accept extra
4879 argument on variable argument list. The argument type must
4880 now be provided to the function. Also, added new function:
4881 silc_command_encode_reply_payload_va which is same as
4882 normal command_encode_payload_va except command status type
4883 is provided as extra argument.
4885 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Added ~./silc directory handling. The directory includes the
4888 public and private keys for the client.
4890 Added silc_client_check_silc_dir, silc_client_create_identifier
4891 and silc_client_load_keys.
4893 * Implemented SILC protocol compliant public key. Added public
4894 and private key saving to and loading from files.
4896 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4897 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4898 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4899 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4900 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4902 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4903 silc_pkcs_load_[public/private]_key.
4905 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Added silc_server_get_route (route.[ch]) to get connection
4908 data for the fastest route for given ID.
4910 * Implemented INVITE command on client and server. The command
