1 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed various compilation problems under WIN32. Affected
4 files lib/silcutil/win32/silcwin32thread.c and
5 lib/silcutil/win32/silcwin32schedule.c.
7 * Removed all _internal.h #includes from public header
8 files. Internal headers must never be included from
11 Removed also the lib/silcske/payload_internal.h file.
13 * All include files that may be needed (public and some others
14 included by the public headers) by application developers are
15 now copied to the ./includes directory. It does not copy any
16 internal headers. Affected file Makefile.defines.pre and all
17 Makefile.am's under lib/ and subdirs.
19 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Do not change the ~/.silc directory's permissions automatically.
22 Affected file irssi/src/silc/core/clientutil.c.
24 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
26 * Do not cancel the protocol in silc_server_close_connection
27 it might cause recursion. Now cancelled in the function
28 silc_server_free_sock_user_data. Affected file silcd/server.c.
30 * Fixed the silc_server_remove_clients_by_server to regenerate
31 the channel keys correctly finally. Added also new function
32 silc_server_remove_clients_channels to actually do it.
33 Affected file silcd/server.c.
35 * Fixed the silc_server_new_channel to not crash by giving
36 wrong router to the new channel. Affected file is
37 silcd/packet_receive.c.
39 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
41 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
42 which is given as argument to the silc_client_alloc now.
43 It can be used to configure the client and set various parameters
44 that affect the function of the client.
46 * The USERS command in server did not check whether the channel
47 is private or secret. Affected file silcd/command.c.
49 * Added new argument to the USERS command in protocol specification.
50 The USERS command now can take the channel name as argument
51 as well. Added support for this in client and server and
52 updated the protocol specs.
54 * Completed the GETKEY command in client. It can be now used
55 to fetch also servers public key not only some clients.
56 Affected files lib/silcclient/command[_reply].c.
58 * Added silc_client_get_server to return server entry by the
59 server name. Affected files lib/silcclient/silcapi.h and
62 * Redefined the IDENTIFY command in protocol specification to be
63 more generic. It now can be used to query information about
64 any entity in the SILC Network, including clients, servers and
65 channels. The query may be based either the entity's name
66 or the ID. Added support for this in both client and server.
68 Affected files silcd/command.c and lib/silcclient/command.c
71 * Optimized the WHOIS and WHOWAS commands in the server. Removed
72 the _from_client and _from_server functions. Affected file
75 * Added silc_client_get_channel_by_id_resolve to the file
76 lib/silcclient/silcapi.h to resolve channel information by
77 its ID. Added also silc_client_get_channel_by_id that
78 does not resolve it from the server.
80 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
82 * Added SilcServerEntry context into the client library
83 to represent one server. The INFO command now allocates
84 these to save the resolved server info. For now on the
85 client library will also keep information about servers,
86 connected and resolved with INFO.
88 The INFO command now allocates the SilcServerEntry context
89 and saves the server info there. The COMMAND_REPLY in
90 the INFO now returns the parameters to application in
91 same order as defined in the protocol specification.
93 The entries are cached in the client->server_cache.
95 * The INFO command is now issued after received the Client ID
96 from the server. Affected file lib/silcclient/client.c.
98 * The CMODE_CHANGE notify may now return also an SilcServerEntry
99 to the application as the mode changer might be server.
100 It is guaranteed that NULL is not returned anymore to the
101 application. Affected file lib/silcclient/client_notify.c.
103 The ID Type is now also passed to the application so that
104 it can check whether the returned entry is SilcClientEntry
107 Added new function silc_client_get_server_by_id to return
108 the server entry by ID. Affected files are the
109 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
111 * Do not create the channel in the Irssi SILC Client when issuing
112 the JOIN command but when received the sucessful JOIN command
113 reply. Otherwise the channel might get created even though we
114 could not join it. The Affected file is
115 irssi/src/silc/core/[silc-channels.c/client_ops.c].
117 * Fixed a channel joining bug in router. The router must also
118 check the channel modes, invite and ban lists etc. when serving
119 the JOIN command sent by normal server. Affected file is
120 silcd/command.c. The router now resolves the client's
121 information from the server who sent the JOIN command if it
122 does not know it, and processes the JOIN command only after
125 * Changed the SilcCommandCb to take new argument; void *context2.
126 Affected file lib/silccore/silccommand.h
128 The second argument in the command callbacks in the server now
129 includes the SilcServerCommandReplyContext if the command was
130 called as pending command callback from the command reply.
131 Otherwise it is NULL. When called as pending the status of the
132 command reply will be checked and if it was erronous the
133 error will be sent to the original sender of the command.
134 This way the client always receives the error messages even
135 though the server was actually the one who received the error
136 when it resent the command to router, for example. Affected
137 files silcd/command[_reply].[ch].
139 * Fixed sending WHOWAS command's error message to client if
140 the requested client could not be found. It was missing.
143 * Changed the CMODE and CUMODE commands reply arguments in the
144 protocol specification. The Channel ID is now sent in both
145 of the commands to identify the channel. Implemented this
146 new feature to the client and server. Affected files
147 lib/silcclient/command_reply.c and silcd/command.c.
149 * Made better checks for invite and ban lists in the JOIN
150 command in server. Affected file silcd/command.c.
152 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
154 * The server now performs the incoming host IP/DNS lookup
155 using the silc_socket_host_lookup and thus does not block
156 the server anymore. Affected file silcd/server.c.
158 * Completed the multi-thread support for SILC Scheduler in
159 the lib/silcutil/silcschedule.c.
161 * Fixed the configure.in.pre to detect the pthread correctly
164 * Fixed a deadlock in silc_task_queue_wakeup in the file
165 lib/silcutil/silctask.c.
167 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
169 * Added new function silc_schedule_wakeup that is used in
170 multi-threaded environment to wakeup the main thread's
171 schduler. It needs to be used when a thread adds a new task
172 or removes a task from task queues. After waking up, the
173 scheduler will detect the task queue changes. If threads
174 support is not compiled in this function has no effect.
175 Implemented the wakeup mechanism to both Unix and WIN32
176 systems. Affected files are lib/silcutil/silcschedule.[ch],
177 lib/silcutil/unix/silcunixschedule.c and the
178 lib/silcutil/win32/silcwin32schedule.c.
180 * Added new function silc_task_queue_wakeup to wakeup the
181 scheduler by the specified task queue. Affected file
182 lib/silcutil/silctask.[ch].
184 * The silc_socket_host_lookup_start now wakes up the scheduler
185 after adding the timeout task. Affected file is
186 lib/silcutil/silcsockconn.c.
188 * The silc_socket_host_lookup is synchronous now if the threads
189 support is not compiled in. However, the callback is still
190 called asyncronously through the scheduler, anyway. Affected
191 file lib/silcutil/silcsockconn.c.
193 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
195 * Added new function silc_socket_host_lookup to perform
196 asynchronous IP and FQDN lookups for the socket connection.
197 Affected files lib/silcutil/silcsockconn.[ch].
199 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
201 * Added SILC_MUTEX_DEFINE to define the mutex on environments
202 that may or may not compile the mutex support in.
204 Changed the silc_mutex_alloc interface. It allocates the
205 mutex now to the sent pointer and returns TRUE or FALSE.
207 Affected file lib/silcutil/silcmutex.h.
209 * Wrote the SILC Task Queue interface to support multi-threads.
210 Affected file lib/silcutil/silctask.[ch].
212 * Wrote the SILC Scheduler to support multi-threads. Affected
213 file lib/silcutil/silcschedule.c.
215 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
217 * Implemented the SILC Mutex API and SILC Thread API for WIN32
218 in lib/silcutil/win32/.
220 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
222 * Defined SILC Mutex API and SILC Thread API and implemented
223 them for Unix. Affected files are
224 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
225 lib/silcutil/unix/silcunixmutex.c and
226 lib/silcutil/unix/silcunixthread.c.
228 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
230 * Fixed the silc_server_remove_clients_by_server's channel
231 key re-generation. The hash table handling was incorrect
232 and would not work with many channels. Affected file is
235 * Fixed some memory leaks around the server code.
237 * Rewrote the silc_server_get_users_on_channel to support IPv6
238 based Client ID's. Affected file silcd/server.c.
240 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
241 specification. However, a separate document must be written
242 to define the detailed signing procedure and the payload
243 associated with the flag. Defined the flag to the
244 lib/silccore/silcchannel.h as well.
246 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Changed the dynamic tables to static size tables in the
249 lib/silccrypt/silchmac.c.
251 * Removed GCC dependencies from the code. A patch by cras.
253 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
255 * Do not show the error "Error receiving packet bla bla"
256 in server if it really was not an error (-2 means that reading
257 is pending). Affected file silcd/server.c.
259 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
261 * Fixed a possible crash in silc_server_remove_clients_by_server
262 in silcd/server.c. Fixed there also some memory leaks.
264 * Fixed the silc_idlist_replace_client_id. It could replace
265 wrong key in the hash table. Affected file silcd/idlist.c.
267 * Do not check whether there are global users on the channel
268 if the channel->global_users is FALSE. Affected functions
269 silc_server_remove_from_one_channel and
270 silc_server_remove_from_channels in silcd/server.c. Also,
271 do not check if the removed client is local as we can be
272 sure that global client was not removed from the channel
273 and checking for global users is not needed.
275 * The silc_server_remove_clients_by_server now re-generates
276 the channel keys correctly for those channels that had
277 clients removed from them. Affected file silcd/server.c.
279 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
281 * Found the reason of random crashes in the server. We weren't
282 ignoring the SIGPIPE signal (which can be sent in write())
283 and it crashed the server. Affected file silcd/silcd.c.
285 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
287 * Assure that sock->user_data is not NULL in the function
288 silc_server_packet_send in silcd/packet_send.c.
290 * Disconnect the remote connection if it could not be added
291 to any ID lists in the server. The affected file is
294 * Check in silc_server_packet_send[_real/dest] that the
295 socket is not disconnecting and ignore the data if it is.
296 Affected file silcd/packet_send.c.
298 * Define inline to __inline on native WIN32 compilation.
299 Affected file includes/silcwin32.h.
301 * Added some explicit type casts for inline code since MSVC
302 require them. Affected files lib/silcutil/silcbuffer.h,
303 lib/trq/silcdlist.h and lib/trq/silclist.h.
305 * Print warning in log files from now on if the packet
306 decryption fails. Affected file silcd/server.c.
308 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Changed the `say' client operation's interface to accept
311 new `type' argument to indicate the type of the message sent
312 by the library. The application may filter the library's
313 messages according the type. The affected file is the
314 lib/silcclient/silcapi.h.
316 * Added two new functions to lib/silcclient/silcapi.h:
317 silc_client_del_client and silc_client_del_client_by_id.
318 Affected file lib/silcclient/idlist.c.
320 * Moved the clientincludes.h from includes/ to silc/ and
321 serverincludes.h from includes/ to silcd/.
323 * The modes for the CMODE and CUMODE are now passed as
324 uint32 for application with COMMAND_REPLY. The affected
325 file is lib/silcclient/command_reply.c.
327 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
329 * /WHOIS without arguments shows client's own information.
330 Affected file lib/silcclient/command.c.
332 * Changed PING to not accept any arguments. The specs
333 says that client can ping only the connected server so
334 requiring an argument is not needed. Affected file is
335 lib/silcclient/command.c.
337 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
339 * Fixed a fatal bug in private message sending and reception
340 encryption and decryption when using private message keys.
341 The implementation was incorrect and did not follow the
342 specification. It causd that some of the message were
343 lost since it did not use the sending and receiving keys
344 as the protocol suggests. This has been fixed and will cause
345 incompatibilities with older clients when sending private
346 message encrypted with private message keys. Affected files
347 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
348 and various other in Irssi SILC Client.
350 Added `responder' boolean argument to the functions
351 silc_client_add_private_message_key[_ske] to indicate when
352 the key is added as responder or initiator of the key
355 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
357 * Removed the silc_ske_check_version function and created
358 a SilcSKECheckVersion callback. Added also a function
359 silc_ske_set_callbacks that is now used to set all SKE
360 callbacks. The callback functions are not given to
361 the SKE functions anymore, but this function is used to
364 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
366 * Added `silc_version' argument to the silc_client_alloc
367 to define the version of the application for the library.
368 The library will use the version string to compare it
369 against the remote host's (usually a server) version
370 string. Affected file lib/silcclient/silcapi.h
372 * Added the KE protocol context to Key Agreement context
373 in client library so that we can abort the SKE if it
374 is in process when we get timeout. Affected file is
375 lib/silcclient/client_keyagr.c.
377 * Do not resolve the client ID forever if it returns in the
378 first time that such client does not exist. This was done
379 for example with private message. Affected file is
380 lib/silcclient/client_prvmsg.c.
382 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
384 * Do not add regex.h for WIN32. The affected file
385 includes/silcincludes.h.
387 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
388 not work yet 100%. It generates the DLL's automatically
389 when compiling with --with-win32 under cygwin.
391 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
393 * lib/contrib/regex.c is not compiled on WIN32.
395 * Added silc_net_get_socket_opt function to the
396 lib/silcutil/silcnet.h.
398 * Added includes/silcwin32.h for WIN32 specific includes
401 * Do not use ptime structure or any of the posix process
402 functions on WIN32 in lib/silccrypt/silrng.c.
404 * Added silc_gettimeofday to provide generic function
405 for struct timeval on all platforms. Added the function
406 to lib/silcutil/silcutil.h.
408 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
410 * Moved the lib/silccore/silcsockconn.[ch] to the utility
411 library as they clearly belong there. As a plus side we
412 can make the actual socket connection routines platform
415 Added also new generic function silc_socket_read and
416 silc_socket_write (that used to be silc_packet_[read/write].
417 The implementation of these are platform specific.
419 * Added WIN32 specific routines of silc_socket_[read/write]
420 to lib/silcutil/win32/silcwin32sockconn.c.
422 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
424 * Added preliminary support for native WIN32 compilation under
425 cygwin (using the -mno-cygwin option for GCC) to the
426 ./configure.in.pre. The --with-win32 now prepares the
427 compilation for native WIN32.
429 * Rewrote the SILC Scheduler interface in the file
430 lib/silcutil/silcschedule.h. The scheduler is now context
431 based and does not have anymore any global static scheduler.
432 Moved the Unix scheduler to the lib/silcutil/unix/ directory
433 and created lib/silcutil/win32 directory for WIN32 based
436 * Added Unix specific network routines to the
437 lib/silcutil/unix/silcunixnet.c and the old
438 lib/silcutil/silcnet.c includes now only generic routines.
440 Added WIN32 specific network routines to the
441 lib/silcutil/win32/silcwin32net.c.
443 * Added Unix specific utility functions from the
444 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
446 * Added WIN32 SILC Scheduler to the file
447 lib/silcutil/win32/silcwin32schedule.c. The code is of course
450 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Do not handle JOIN notify in the server if the target client
453 is not registered (idata->registered == FALSE). The affected
454 file is silcd/packet_receive.c.
456 * Update the nickrec->founder in event_cumode in the Irssi SILC
457 client. Affected file irssi/src/silc/core/silc-channels.c.
459 * Fixed the CUMODE_CHANGE notify handling in the server when
460 server and router are announcing their clients on channels.
461 Now the mode changes are saved and notified correctly. The
462 affected file is /silcd/packet_receive.c.
464 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
465 They really did not replace the cache entry in the ID Cache.
466 Now they do that. Affected file silcd/idlist.c.
468 * Fixed the KICK notify handling in the Irssi SILC client to
469 update the channel records so that the kicked client does not
470 appear to be on the channel. The affected file is
471 irssi/src/silc/core/silc-channels.c.
473 * Always update the conn->current_channel when executing command
474 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
476 * Fixed the KILL notify handling in Irssi SILC client to remove
477 the killed client on all channels.
479 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Fixed the silc_parse_command_line to remove extra spaces
482 from the start and end of the arguments. Affected file is
483 lib/silcutil/silcutil.c.
485 * Cancel and free any active protocol in the function
486 silc_server_close_connection. Affected file silcd/server.c.
488 * Cancel and free any active protocol in the function
489 silc_client_close_connction. Affected file is
490 lib/silcclient/client.c.
492 * Do not execute the KILL command for clients that are in
493 history (ie. they are not in the network). Affected file is
496 * Fixed KILL notify handling, client does not crash anymore.
497 Affected file irssi/src/silc/core/silc-channels.c.
499 * Reduced the default packet buffer size from 2048 to 1024 in
500 lib/silccore/silcpacket.c.
502 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
503 counter to the SKE context that is incresed when the SKE library
504 performs async operation outside the library. If the outside
505 process frees the SKE context and FREED status will be set
506 and the library will detect after the sync operation that the
507 libary is freed. The affected files are
508 lib/silcske/silcske[_status].[ch].
510 * Resolve the client entry information in the function
511 silc_client_channel_message to assure that NULL pointer is not
512 passed as client entry to the application. */
514 * Fixed the task timeout calculation to assure that there is
515 never negative timeouts. The affected file is
516 lib/silcutil/silcschedule.c.
518 * Fixed the channel user mode notification sending in server.
519 It was sent point-to-point to the router (or to server by router)
520 but it needs to be destined to a channel. The routines now
521 supports sending the channel user mode notifys to the channels
522 when announcing clients and channels. Affected files are
523 silcd/server.c and silcd/packet_receive.c.
525 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
526 It did not actually replace the old channel entry in the cache.
527 Affected file lib/silcclient/client_notify.c.
529 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Fixed a possible crash in silc_packet_send_prepare. It now
532 assures always that there is enough space in the buffer and
533 at the tail area of the buffer (for MAC).
535 Fixed the inbound buffer reallocation in silc_packet_read.
536 It was old code and did not handle the reallocation correctly.
539 The affected file is lib/silccore/silcpacket.c.
541 * Fixed buffer overflow in silc_parse_nickname in the file
542 lib/silcutil/silcutil.c.
544 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * make install generates new server keys only if there is not
549 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
552 Added check that if the NOREPLY is set then we will not send
553 the away message. This avoids infinite loop of away messages
554 if both clients are away. The affected file is
555 lib/silcclient/client_prvmsg.c.
557 * Fixed client crash if /NICK was given without arguments.
558 Affected file lib/silcclient/command.c.
560 * Server does not send the invite list in INVITE command back
561 to the client if the list was not altered. Added this notion
562 to the protocol spec as well. Affected file silcd/command.c.
564 Fixed possible crash in INVITE command by checking the
565 value of silc_server_get_client_route command.
567 * Fixed the INVITE notify type handling. The arguments are now
568 taken in correct order and client does not crash. The affected
569 file is irssi/src/silc/core/silc-channels.c.
571 Removed the "Inviting xxx to channel" message from the
572 client library away and let the application handle it.
573 Affected file lib/silcclient/command.c. Added that message
574 to Irssi SILC client's message formats.
576 * Fixed CMODE command crash in client. It now checks the
577 amount of arguments correctly and does not crash. The affected
578 file is lib/silcclient/command.c.
580 * Do not create new channel automatically in silc_channels_join
581 but check whether the channel by that name already exists.
582 Affected file irssi/silc/core/silc-channels.c.
584 * Do not send the SERVER_SIGNOFF to router if the disconnected
585 entity was the router. Affected file silcd/server.c.
587 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
588 SILC client as it was missing from there.
590 Added the handling of the KICK notify to the Irssi SILC client
591 as it was missing. Added "you have been kicked" message to
592 Irssi SILC client's message modules formats.
594 Added the handing of the KILL notify to the Irssi SILC client
595 as it was missing. Added the kill message module formats
598 The affected file is irssi/src/silc/core/silc-channels.c.
600 * The router did not save the channel mode the server announced.
601 Affected file silcd/packet_receive.c.
603 * Fixed a possible crash in INFO command in server. If the
604 server did not provide the server info it crashed. Affected
605 file silcd/command.c.
607 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Fixed the GETKEY command in the server to check also the
610 global list. Otherwise the GETKEY would not work correctly
611 in normal SILC server. Affected file silcd/command.c.
613 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * Fixed GETKEY crash, it crashed if the command did not succseed.
617 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
620 is now real and not just an macro interface to GMP.
622 Removed the entire GMP from the source tree and imported new
623 NSS MPI library instead. Reason for removing GMP is that it is
624 extremely large and compiles extremely slow. The NSS MPI
625 is only a few files and compiles in less than 10 seconds.
626 The speed is also about the same as GMP. The MPI is imported
629 If the system has GMP installed we will still use the GMP.
630 If it is not then the NSS MPI will be compiled.
632 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Merged a long nickname (127 characters long) crash bugfix from
635 Irssi CVS tree. Affected file irssi/src/core/misc.c.
637 * Merged a freed memory reference bugfix from Irssi CVS tree.
638 Affected file irssi/src/core/commands.c.
640 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Added the server's public key sving and verification to the
643 server when performing the SKE. This was missing and the
644 remote server's (or router's) public key was accepted without
645 checking whether we have it previously or trust it at all.
646 Affected file silcd/protocol.c.
648 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Check in the silc_server_timeout_remote if protocol is active
651 and make sure that the protocol's final callback is called so
652 that all memory if freed. Affected file silcd/server.c.
654 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * silc_server_whois_send_reply crashed the server if the nickname
657 was 127 characters long. Affected file silcd/command.c.
659 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Added sanity check to the silc_server_new_client. If the hostname
662 is provided inside username then check that the provided hostname
663 really is the same as the resolved one. If the hostname was not
664 resolved then check it from the public key. Affected file is
665 silcd/packet_receive.c.
667 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
668 if the server disconnected us and the connection is not valid
669 anymore. Affected file irssi/src/silc/core/silc-channels.c.
671 * Moved the silc_client_[chmode|chumode|chumode_char] away from
672 the library to the lib/silcutil/silcutil.[ch].
674 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Close log file after open. Affected file
677 lib/silcutil/silclog.c.
679 * Check whether sock == NULL in silc_client_send_packet and return
680 if it is. Affected file lib/silcclient/silcclient.c.
682 * Check rec->entry == NULL in the Irssi SILC Client before
683 sending the channel message. Affecte file is
684 irssi/src/silc/core/silc-servers.c.
686 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * Merged a splitted window bugfix from Irssi CVS tree. The
689 affected file is irssi/src/fe-text/textbuffer-view.c.
691 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
692 It did not print nickname.
694 * Improved the distributions system a bit.
696 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
699 irssi/src/fe-text/gui-window.c.
701 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
702 to in-active server. The affected file is
703 irssi/src/silc/core/client_ops.c.
705 * Resolve the client in USERS command reply if the entry does
706 not have username resolved. The affected file is
707 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
708 command to WHOIS command to really resolve stuff. The USERS
709 is not used any more in any critical section so WHOIS can
710 be used even though it might be slower than IDENTIFY.
712 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
715 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Changed the protocol API a bit more consistent in the
718 lib/silccore/silcprotocol.[ch].
720 * Changed the following headers to ROBODoc format:
722 lib/silccore/silcpayload.h
723 lib/silccore/silcprotocol.h
724 lib/silccore/silcsockconn.h
726 All core library headers are now formatted.
728 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Fixed a bug in Irssi SILC client; do not show that you are
731 server/router operator if you really are not. Affected file is
732 irssi/src/silc/core/client_ops.c.
734 * Renamed silc_command_free_payload to silc_command_payload_free.
735 Affected file lib/silccore/silccommand.h
737 * Added silcmath.h to include the prototoypes of various routines
738 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
741 * Changed the following headers to ROBODoc format:
743 lib/silccore/silcchannel.h
744 lib/silccore/silccommand.h
745 lib/silccore/silcid.h
746 lib/silccore/silcidcache.h
747 lib/silccore/silcmode.h
748 lib/silccore/silcnotify.h
749 lib/silccore/silcpacket.h
750 lib/silcmath/silcmath.h
752 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Added checking to the server code not to start the server if
755 ciphers and stuff are not configured properly. Affected files
756 silcd/serverconfig.[h] and silcd/server.c.
758 * Changed the layout of the header files of the public interfaces
759 in the SILC libraries. The new layout supports ROBODoc
760 documentation tool (and some others) so that it is easy to create
761 a library reference manual. All the other headers and source
762 code must still follow the CodingStyle document. Also source
763 code must not include these ROBODoc stuffs, only the headers.
764 Furthermore, all public interface headers must now be named
765 by using `silc' prefix, example: silcapi.h, silccipher.h.
766 Some files were renamed due to this. All the other headers
767 must not be used as public interfaces. I will update the
768 CodingStyle document later. Changed following headers, so far:
770 lib/silcclient/silcapi.h
771 lib/silccore/silcauth.h
772 lib/silccore/silcprivate.h
773 lib/silccrypt/silcdh.h
775 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Removed silc_client_packet_send_flush from the client library
780 as it is not needed. Affected file lib/silcclient/client.[ch].
782 * Added printing of message of unresolved authentication method
783 to the Irssi SILC client. Added it to the module formats.
784 Removed the same message from the client library.
786 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Added new distribution feature, DISTLABEL. Every distribution
789 can define own preprocessor label that can be used in the
790 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
791 file distributions, acconfig.h.pre and prepare.
793 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Added Makefile.defines_int to include the actual definitions
796 for Makefile.defines.in. Tested the new distribution system,
797 created distributions and tested installation.
799 * Added AWAY message printing to the Irssi SILC client. Added
800 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
802 * Added SCONNECT command to call the SILC's CONNECT command.
803 Cannot use CONNECT directly since Irssi uses that internally.
804 Affected file irssi/src/silc/core/silc-servers.c.
806 Added ACTION local command. It is same as ME command but takes
807 the channel as mandatory argument.
809 Rewrote some of the Irssi's help files to suite for SILC
812 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Added Makefile.defines[.in] that should for now on be included
815 in all Makefile.am file in the source tree. That file includes
816 all common compilation definitions for SILC source tree.
818 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Minor changes to the ./prepare script to change the package
821 name according the distribution name to the configure.in.
823 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Created new distribution system. Added file `distributions'
826 that defines all the distributions that can be created out of
827 the SILC source tree. The ./prepare script now reads that
828 file to determine how to prepare the distributions. The
829 first argument to the ./prepare is the name of the distribution
830 and second is the version of the distribution. If given
831 without arguments it creates the default (toolkit) distribution
832 with the default version (defined in ./prepare).
834 All Makefile.am files that are subject to the distributions
835 are now named as Makefile.am.pre. These are ./Makefile.am
836 and lib/Makefile.am. Others may be changed later.
838 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Added invite list, ban list, some key management and connection
841 error message printing to module formats in the Irssi SILC client.
843 * Added new silc_client_set_away_message to set the away message
844 that is back to the person who sent private message. The
845 affected file lib/silcclient/silcapi.h and the
846 lib/silcclient/client_prvmsg.c.
848 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
850 * Fixed the private message sending in the Irssi SILC client,
851 added local command KEY to the Irssi SILC client.
853 Added key management and key agreement message formats to the
854 irssi/src/fe-common/silc/module-formats.[ch].
856 Added USERS (alias WHO) printing, server/router operator
857 indication and LIST command printing to the module formats.
859 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Fixed channel joining notify handling, cumode notify handling
862 from Irssi SILC client.
864 * Added SILC specific module-formats to the Irssi SILC client so
865 that SILC specific message hilighting, colors etc is possible.
866 Affected file irssi/src/fe-common/silc/module-formats.[ch].
868 Added channel mode, channel user mode, actions, notices,
869 whois and whowas printing to the the module-formats.c.
871 * Fixed a bug in channel deletion in the server. The channel
872 is not left to the cache even if the channel founder auth mode
873 is set when there are no users anymore on the channel. Affected
876 * The silc_net_localhost now resolves the entire hostname including
877 the domain name. Affected file lib/silcutil/silcnet.c.
879 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Changed the ask_passphrase client operation to be ascynchronous.
882 It has now a completion callback and a context that the
883 application must call after it has got the passphrase from
884 the user. Affected files lib/silcclient/silcapi.h,
885 lib/silcclient/protocol.c, lib/silcclient/command.c and
888 Added SilcAskPassphrase callback that the application calls
889 to deliver the passphrase to the library.
891 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
892 The public key verification and especially a certificate
893 verification is asynchronous procedure.
895 Added new SILC_SKE_STATUS_PENDING status to indicate the
896 request is pending and a callback will be called to finalize
899 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
900 indicate that remote end did not send its public key (or
901 certificate), even though we require it. Added check for this
902 condition in the SKE. This was a security bug, now fixed.
904 Defined new SilcSKEVerifyCbCompletion callback that is called
905 when the verification process is completed.
907 The affected files lib/silcske/silcske_status.h and
908 lib/silcske/silcske.[ch].
910 * Changed the verify_public_key client operation to be async
911 as well. Defined SilcVerifyPublicKey callback that is used to
912 indicate the success of the public key verification process.
914 Changed the server and client to use the new async client
917 * Changed the Irssi SILC client's internal scheduler to be called
918 twice as many times as it used to be. As a result the client
919 should be a bit faster now. Affected file is
920 irssi/src/silc/core/silc-core.c.
922 * Added support to Irssi SILC client of asynchronous public key
923 verification and passphrase inquiry. Affected file is
924 irssi/src/silc/core/silc-core.c.
926 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Do not say "You have left channel %s" in client library.
929 Moved it to the application. Affected files are
930 lib/silcclient/command.c and silc/client_ops.c.
932 * Fixed silc_client_get_clients. Command context was not
933 duplicated and was freed memory in the callback. Affected
934 file lib/silcclient/idlist.c.
936 * Do not say "you are now talking..." on JOIN command in the
937 client library. The appliation must handle it.
939 * Do not say ".. changed topic to" in command reply in the
940 client libary. The application must handle it.
942 * Fixed TOPIC command sending in the client library.
944 * Fixed a memory leak in silc_client_command_free in the file
945 lib/silcclient/command.c.
947 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Imported a modified version of Irssi client to the source tree.
950 The Irssi will be used to create a new client called
951 Irssi SILC. Imported to irssi/.
953 Added silc_core_init_finish function to the Irssi. Affected
954 file irssi/configure.in.
956 A lot changes in the Makefile.ams around the irssi tree.
958 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Do not rehash if the new size is same as the old size of the
961 hash table, in the silc_hash_table_rehash*. The affected file
962 lib/silcutil/silchashtable.c.
964 * Replaced hash_table_del_by_context calls from the server
965 (when channel->user_list and client->channels) to the
966 hash_table_del as it is sufficient and faster.
968 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Added silc_hash_table_list, silc_hash_table_get and the
971 SilcHashTableList structure to provide an alternative way to
972 traverse the hash table. The affected files are
973 lib/silcutil/silchashtable.[ch].
975 * Changed the server's idlist routines to use the hash table
976 routines to optimize the code.
978 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Replaced the client entry's `channel' list and channel entry's
981 `user_list' list to hash tables for optimized lookup. Changed
982 the code to use the hash table interface around the code.
983 Affected file lib/silcd/idlist.[ch].
985 * Added `auto_rehash' boolean argument to the function
986 silc_hash_table_alloc to indicate whether the hash table should
987 auto-rehash when it thinks is appropriate time. It will
988 increase the hash table size if the there is twice as much
989 entries in the table than the size of the table, and will
990 decrease the size if there are twice as less entries than
991 the size of the table.
993 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Fixed silc_xxx_get_supported to not crash at some circumstances.
997 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * silc_idcache_purge_by_context deletes the entry now by context
1000 as it is supposed to do. Affected file lib/silccore/idcache.c.
1002 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1003 client is not anymore valid (WHOWAS givens the info) and not
1004 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1006 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1008 * Removed the `data' and `data_len' arguments from the ID Cache
1009 interfaces and added `name' argument. ID Cache does not handle
1010 anymore the binary data only a names associated with given ID.
1012 * When hashing a Client ID with silc_hash_id the entire ID is
1013 not hashed anymore, instead only the hash of the Client ID is
1014 hashed. This way we can access the Client ID from the cache
1015 with Client ID but with the hash of the ID (which is a hash of
1016 the nickname) as well without any difference in performance.
1018 Added also silc_idcache_find_by_id_one_ext to do one on one
1019 searching when we have the actual ID. Added also function
1020 silc_hash_client_id_compare. The affected files are
1021 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1023 * When hashing the name associated with a ID it is always done
1024 in lowercase. This way we can access the cache without worrying
1025 about case-sensitivity, even though, for example nicknames are
1028 * Fixed a bug in server with channel message sending. It put
1029 wrong ID type as destination ID. The affected file
1030 silcd/packet_send.c.
1032 * silc_idcache_del_by_context now deletes from all hash tables
1033 by context. Affected file lib/silccore/idcache.c.
1035 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Changed the client library to use the new ID Cache interface.
1038 Changes around the source tree.
1040 * Added silc_hash_table_rehash_ext to rehash with specific
1041 hash function. Affected file lib/silcutil/silchashtable.[ch].
1043 * Added silc_hash_string_compare to compare two strings in the
1044 hash table. Affected file lib/silcutil/silcutil.[ch].
1046 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Added new function silc_idcache_del_by_context into the
1049 lib/silccore/idcache.[ch].
1051 * Changed the server's ID list routines to use the new ID Cache
1052 interface. Changes around the source tree.
1054 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Added silc_hash_table_del[_by_context]_ext functions in to the
1057 lib/silcutil/silchashtable.[ch].
1059 Removed silc_hash_table_find_all* routines and added new
1060 silc_hash_table_find_foreach to replace them.
1062 Added silc_hash_table_replace_ext function as extended
1063 replacing function. Separated the simple hash table interface
1064 from the extended hash table interface in the file
1065 lib/silcutil/silchashtable.h.
1067 * Fixed minor bugs and changed it to use some of the new
1068 hash table functions in lib/silccore/idcache.c
1070 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1072 * Added new function silc_hash_table_find_all to return all keys
1073 in the hash table by the specified key. As the hash table is
1074 collision resistant it also makes it possible to have several
1075 duplicate keys in the hash table. This function may be used to
1076 find all of the keys from the hash.
1078 Added user_context arguments to the SilcHashFunction,
1079 SilcHashCompare and SilcHashDestructor to deliver user specified
1082 Added new fuctions silc_hash_table_find[_all]_ext to do
1083 extended lookup with specified hash and compare functions and
1084 specified user contexts.
1086 Added new function silc_hash_table_add_ext to add the key
1087 with specified hash function and user context.
1089 Added new function silc_hash_table_foreach to traverse all
1090 entrys in the hash table. Added SilcHashForeach callback
1093 Added new function silc_hash_table_del_by_context to delete
1094 the entry only if the context associated with the key matches.
1096 Affected files are lib/silcutil/silchashtable.[ch].
1098 * Removed silc_hash_[server/client/channel]_id and added just
1099 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1100 silc_hash_id_compare to compare two ID's using as the hash table
1101 comparison function. Added also silc_hash_data to hash
1102 binary data and silc_hash_data_compare to compare it.
1104 * Removed silc_idlist_find_client_by_hash as it is not needed
1105 anymore. Affected file silcd/idlist.[ch].
1107 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1108 to use internally the SilcHashTable. The new ID Cache is a lot
1109 faster than the old one. Some of the ID Cache interface was also
1110 rewritten and obsolete and stupid functions were removed.
1112 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Added entry_count field to the SilcHashTable to keep the number
1115 of the entries in the table. Implemented the function
1116 silc_hash_table_rehash. Added new function
1117 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1119 Fixed a minor bug in silc_hash_table_free.
1121 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1122 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1123 into the lib/silcutil/silcutil.[ch].
1125 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Implemented a collision resistant hash table into the
1128 lib/silcutil/silchashtable[ch]. See the header and the source
1129 for the SilcHashTable API.
1131 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Merged dotconf version 1.0.2 into lib/dotconf.
1135 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Do not compile anything in lib/silcsim/* if the SIM support
1138 is not enabled. The tree should now compile without problems
1141 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Compiled the SILC under cygwin. Compiled and tested briefly
1144 without problems. More tests needed. The SIMs didn't compile
1147 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1149 * Fixed possible crash in silc_get_username in the
1150 lib/silcutil/silcutil.c.
1152 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Fixed a va_arg in silc/client_ops.c.
1156 * Oops, RC5 routines were named AES and caused some problems
1157 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1159 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Added new SilcIDIP structure into the lib/silccore/id.h and
1162 replaced the old `ip' fields from all SILC ID's to that type.
1163 This is a step towards IPv6 support.
1165 The silc_id_get_len takes now the ID as an extra argument.
1166 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1167 both IPv4 and IPv6 based ID's.
1169 The affected files are lib/silccore/id.[ch] and other files
1170 around the tree using these routines.
1172 * Removed the ID length arguments in server from various
1173 silc_server_send_notify_* routines -> they are not needed
1176 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Fixed memory leak in silc_encode_pem_file in the file
1179 lib/silcutil/silcutil.c.
1181 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1183 * Check minor version as well in the SKE. Affected files are
1184 silcd/protocol.c and lib/silcclient/protocol.c.
1186 * Added --identifier option to the server so that an identifier
1187 can be when creating the public key for the server. Affected
1188 file is silcd/silcd.c.
1190 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1191 lib/silccrypt/silcpkcs.c.
1193 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1195 * Register default ciphers and stuff when using -C option with
1196 the server. Affected file sildc/silcd.c.
1198 * Put back the servers public key filename format, it is better
1199 than the new one. For now, the client keys are saved with the
1200 new filename format. The affected file silc/client_ops.c.
1202 * Implemented the Cipher API for the rest of the ciphers that
1203 did not implement it or implemented it the wrong way.
1205 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Register default ciphers and stuff when using the -S option
1208 in the client. Affected file silc/silc.c. Same also when
1209 creating new key pair with -C option.
1211 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Fixed the silc_verify_public_key client operation function to
1214 save the public keys differently. The fingerprint is now
1215 used as filename and not the hostname. This way also the
1216 client keys are saved uniquely and not with hostnames. The
1217 affected file is silc/client_ops.c.
1219 * Trimmed the silc_hash_fingerprint function to remove extra
1220 whitespaces from the end of the fingerprint. The affected
1221 file is lib/silccrypt/silchash.c.
1225 * Added silc_cipher_register_default function to register all
1226 default ciphers. It can be used when configuration files
1227 does not exist and the application does not want any specific
1228 ciphers in any specific order.
1230 The SilcDList is now used as silc_cipher_list dynamically
1231 allocated cipher list. Removed the static list all together
1232 and now all ciphers must be allocated to the dynamic list.
1233 The silc_cipher_alloc routine was changed to check only the
1236 All silc_cipher_* routines that used to return int returns
1239 The affected files lib/silccrypt/silccrypt.[ch].
1241 * The same thing was done to silc_hash_* as for silc_cipher_*
1242 routines. Affected files lib/silccrypt/silchash.[ch].
1244 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1245 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1246 Added also silc_pkcs_[un]register[_default] functions.
1247 Removed the data_context from the PKCS API.
1249 * Added silc_hmac_register_default function to register default
1250 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1251 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1252 to unregister all hmacs at once.
1254 * Register the default ciphers, hash functions, PKCSs and HMACs
1255 if client's configuration file does not exist. The affected
1258 * The client did not load the hash functions from the SIM
1259 modules at all. Added support for this. Affected file is
1260 silc/clientconfig.c.
1262 * When decoding public key with silc_pkcs_public_key_decode, check
1263 the supported algorithm only if PKCS are registered. Affected
1264 file lib/silccrypt/silcpkcs.c. The same was done with the
1265 silc_pkcs_private_key_decode.
1267 * Fixed the SILC List routines to keep the list always in order.
1268 It used to change the list's order when traversing the list but
1269 not it preserves the order. Affected file lib/trq/silclist.h.
1271 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Added the client library to use the SilcSocketConnection's
1274 reference counter (by silc_socket_dup) to prevent the bug that
1275 the socket object may be freed underneath async operation.
1277 * The name resolv library checking fixes in the configure.in.pre.
1280 * Created new version of the protocol drafts for future
1281 development. The -03 drafts are the ones that will be changed
1282 in the trunk now and the -02 will remain as they are.
1284 * Send list of CUMODE notifys to the router when announcing
1285 the channel users to the router. Affected file silcd/server.c.
1286 If the router receiving channel founder CUMODE for a channel
1287 that already has channel founder it will send CUMODE notify
1288 to the sender to remove the channel founder rights from the
1289 announced client. Affected file silcd/packet_receive.c.
1291 * The CUMODE notify may now use Server ID as well as the entity
1292 who changes the mode. Updated protocool specs.
1294 * Updated INSTALL and README files.
1296 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * New web pages in the http://silc.pspt.fi. The pages was
1303 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Implemented the [DenyConnectin] config section in the server.
1306 Added silc_server_config_denied_conn to check whether incoming
1307 connection is denied. Affected file silcd/serverconfig.[ch].
1309 * Do not check the ports when checking the incoming configuration
1310 data if the port is 0, meaning any. Affected file is
1311 silcd/serverconfig.c.
1313 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Fixed buffer overflow in silc_string_compare in the file
1316 lib/silcutil/silcutil.c.
1318 * Fixed double free in silc_server_command_leave in the file
1321 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Fixed the version checking in the server. Affected file is
1326 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1328 * Fixed the configuration data fetching when accepting new
1329 connections in the server. Affected file silcd/server.c.
1331 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1333 * Added `sender_entry' argument to the function
1334 silc_server_packet_relay_to_channel so that we can check
1335 whether some destination actually belongs to the same route
1336 the sender belongs (ie, we must not resend the packet to the
1337 sender). Affected file silcd/packet_send.[ch].
1339 * Added `servername' field to the SilcClientEntry in the server
1340 to hold the name of the server where client is from. Affected
1341 file is silcd/idlist.h.
1343 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Moved the channel message encrypting in the router betwen
1346 router connections from silc_server_channel_message to the
1347 silc_server_packet_relay_to_channel since we want to check
1348 whether we have anybody channel before encrypting anything.
1349 Affected files silcd/packet_[receive/send].c.
1351 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Fixed the [AdminConnection] server config section to support
1354 multiple entries. Affected file silcd/serverconfig.c.
1356 * Added support into the server to check the validity of the
1357 incoming connection before executing any KE or authentication
1360 * The connection configuration is now saved to the KE and
1361 connection auth protocol contexts and not fetched anymore in
1362 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1364 * The local hosts listenning address and port is also resolved
1365 now when starting the server. We want to have the socket object
1366 to include the real address and port for the listener. Added
1367 new function silc_net_check_local_by_sock into the files
1368 lib/silcutil/silcnet.[ch].
1370 * Fixed a broadcast bug in server -> do not broadcast if we
1373 * Fixed a routing bug. Do not route broadcast packets ever.
1374 Broadcast packets must be processed always and not routed since
1375 they may be destined to some other host than yourself and thus
1376 would get routed without no good reason. Affected file is
1379 * Added function silc_server_config_is_primary_route to check
1380 whether primary router connection has been configured (a router
1381 configuration that we are initiating). If there is not, we
1382 will assume that there is only two routers in the SILC network
1383 and we will use the incoming router connection as our primary
1384 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1386 * Changed the order of the broadcasting. Broadcast _after_ the
1387 packet has been processed not before. Affected file is
1390 * Fixed a [ClientConnection] parsing bug. The port was never
1391 parsed correctly thus resulting to port 0. Affected file
1392 silcd/serverconfig.c.
1394 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1395 argument and did not set the broadcast packet flag. Affected
1396 file silcd/packet_send.c. Fixed same bug in the function
1397 silc_server_send_notify as well.
1399 * If we receive NEW_ID packet for our own ID in the server, ignore
1402 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1406 * Removed the nickname from the Private Message Payload.
1407 Updated the code and the protocol specs.
1409 * Updated protocol specs for submitting to the IETF.
1411 * Tweaked the Random Number Generator a bit. Affected file
1412 lib/silccrypt/silcrng.c. Exported a new function
1413 silc_rng_[global]_add_noise which can be used to add more
1416 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Do not parse packets with different timeout when protocol
1419 is active -> may cause problem with rekey. Affected file
1422 * When server receives signoff notify it must not create
1423 new channel key if the client is on any channels since the
1424 sender of the signoff notify will create it.
1426 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Added printing of error messages during SKE protocol from the
1429 failure packet sent by server during SKE. Affected file
1432 * Removed the client's failure_callback handling with timeout
1433 and handle it immediately when received.
1435 * The SKE library returned wrong type in SUCCESS and FAILURE
1436 packets. They must be 32 bit MSB not 16 bit MSB.
1438 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1440 * Ok, rewrote the logic of the re-key and now it seems to work.
1441 I tested it on high traffic with frequent re-keys without
1442 problems. Added hmac_receive (and renamed hmac to hmac_send)
1443 in SilcClientConnection in lib/silcclient/client.h and
1444 in SilcIDListData in silcd/idlist.h. Also, removed the
1445 SilcPacketParserContext's cipher and hmac fields as they are
1446 not needed anymore and actually caused some problems when
1447 the ciphers and hmac's changed underneath the packet parser.
1449 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * If re-key protocol is active then process the incoming packets
1452 synchronously since we must assure that icoming packets encrypted
1453 with the old key is processed before the new keys is set to
1454 use. This is true other packets than for REKEY packets.
1455 Affected file silcd/server.c. The same was done to client library
1456 as well, affected file lib/silcclient/client.c.
1458 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Fixed bug in client and server to accept the force send if
1461 the packet is send from silc_[server/client]_packet_process
1462 function. Otherwise the packets are never delivered, oops.
1464 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1466 * Disable force sending of packets when REKEY protocol is active.
1467 We must assure that no packet is sent directly when rekey is
1468 performed. All packets must be sent through packet queue.
1469 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1470 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1471 function is silc_[server/client]_packet_send_real to check
1474 * Replaced the SIM paths from example config files to
1475 /usr/local/modules. Also, make install creates now
1476 /usr/local/silc/logs directory to hold all the SILC server
1479 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * Made the configure.in.pre work on Solaris. Patch by salo.
1483 * Made all ciphers compatible with non-x86 machines. Defined
1484 CBC mode macros into lib/silccrypt/ciphers_def.h.
1486 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Fixed the make install.
1490 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * When MAC computation fails the silc_packet_decrypt returned 0
1493 even though it was supposed to return -1. Fixed this. The
1494 affected file is lib/silccore/silcpacket.c.
1496 * Do not replace the config files in /etc/silc (in make install)
1497 if they already exist. Affected file ./Makefile.am.
1499 * Do not send re-key packets immediately but through packet queue.
1500 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1502 * Changed silc_net_check_host_by_sock to return FALSE if the
1503 IP/DNS could not be resolved. Though, it returns the IP address
1504 now even if it could not resolve it (but returns also FALSE).
1505 Affected file lib/silcutil/silcnet.[ch].
1507 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Added silc_pkcs_decode_identifier to decode the public key's
1510 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1511 Added also silc_pkcs_free_identifier. Added also new context
1512 SilcPublicKeyIdentifier.
1514 * Added -S option to the silc client. It is used to dump the
1515 contents of the specified public key file.
1517 * Changed the PKCS api to return the public key length when
1518 setting the public key.
1520 * Fixed a fatal bug in the public and private key file loading.
1521 Affected file lib/silccrypt/silcpkcs.c.
1523 * Execute the packet parsing for client with zero (0) timeout
1524 if the protocol is active. Affected file silcd/server.c.
1526 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Made the key generation options to the silcd program. Added
1529 -C option, equivalent to client's option.
1531 * Added new [ServerKeys] config section to the server. It
1532 configures the server's public and private key.
1534 * Defined generic Public Key Payload into the protocol
1535 specification to send specific type of public keys and
1538 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1539 public key or certificate.
1541 * Implemented the GETKEY command to the server and to the
1542 client library and on user interface.
1544 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Made preliminary `make install' work.

1575 SilcClientConnection structure; not needed. Affected file is
1576 lib/silcclient/client.h.
1580 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Do not ask whether user wants to use the negotiated private key
1583 for private messages, just use it. Affected file is
1584 silc/local_command.c.
1586 * Added `send_enc_key' and `enc_key_len' fields to the
1587 SilcIDListData structure since they are needed in the re-key
1588 phase. Affected file is silcd/idlist.[ch].

1602 the PFS is to be performed in the re-key. Affected file is
1605 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1608 int64 of at least the xintXX size. If void * is less that 4
1609 bytes uint32 * will be used. Defined bool as boolean.
1611 * Changed _ALL_ unsigned long and unsigned int to uint32,
1612 unsgined short to uint16 in the source tree.
1614 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1615 not handle clients that has entry->data.registered == FALSE.
1616 They are not in the network anymore. Affected file is
1619 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1621 * Implemented the sending of the SERVER_SIGNOFF notify in the
1622 server. Affected file is silcd/server.c.
1624 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

1633 implemnted the printing of the SERVER_SIGNOFF info to the
1634 application. Affected file silc/client_ops.c.
1636 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1637 if the deleting was successful. Affected file silcd/idlist.[ch].
1639 * Added support for public key authentication in the connection
1640 authentication protocol in the client library. Affected file
1641 lib/silcclient/protocol.c.
1643 * Changed the server's silc_idlist_get_clients_by_* interface
1644 to support already allocated array so that new entries may be
1645 added to pre-allocated array. Affected file silcd/idlist.[ch].
1646 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1647 and command replies.
1649 * All command reply functions in the server now calls the
1650 pending command callback even if error occured. This way the
1651 error will be delivered to the client as well. Affected files
1652 silcd/command.c and silcd/command_reply.c.
1654 * Fixed INFO command to return local server's info if no server
1655 was provided. Affected file lib/silcclient/command.c.
1657 * Removed RESTART command for good. Updated the code and the
1660 * Rewrote parts of the task system. It is a bit simpler now.
1661 Removed unsued task priorities. The affected files are
1662 lib/silcutil/silctask.[ch].
1664 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Moved the USERS printing from the library to the application.
1667 Affected files lib/silcclient/command.c and silc/client_ops.c.
1669 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Added channel key re-key support. The re-key is perfomed
1674 only by the router and is done once in an hour. Added `rekey'
1675 field to the SilcChannelEntry in the server. Affected files
1676 silcd/server.c and silcd/idlist.h.
1678 * Added silc_task_unregister_by_context into the file
1679 lib/silcutil/silctask.[ch].
1681 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Added SILC_UMODE_GONE mode to indicate when the client is not
1684 present in the SILC network. Added also support to the local
1685 command AWAY that will set this mode. Added support of showing
1686 "xxx is gone" in WHOIS command. The USERS command shows the
1687 gone status as well.
1689 * Fixed setting server and router operator privileges in the
1690 server's UMODE command. Affected file silcd/command.c.
1692 * Merged the SKE KE1 and KE2 payloads into one payload. The
1693 new KE payload is equivalent to the old KE2 payload.
1695 Cleaned up the SKE Start Payload parsing. It now uses the
1696 simple buffer unformatting to do the parsing. A lot faster
1699 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1700 to the SKE that is used to indicate whether both of the SKE
1701 parties should perform authentication. By default only the
1702 responder performs authentication. By setting this flag also
1703 the initiator must do authentication. By default it is unset
1704 since in normal SKE case, client to server connection, only
1705 the responder should do authentication. When doing SKE between
1706 two clients both should perform authentication. Updated the
1707 code and the protocol specs.
1709 * A little fix to IDENTIFY command in the server. Search the
1710 client first by hash not nickname. Affected file is
1713 * Fixed the silc_client_close_connection to support closing
1714 the client to client connections wihtout deleting too much
1715 data. Affected file lib/silcclient/client.c.
1717 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1718 are received if protocol used to be active but is not anymore
1719 the application would crash due to NULL pointer dereference.
1720 Affected files silcd/server.c and lib/silcclient/client.c.
1722 * Added `hash' field to the SilcClientConnection to include
1723 the hash function negotiated in the SKE protocol.
1725 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1726 to set the channel founder authentication data. A client can
1727 claim the founder rights later by providing the authentication
1728 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1729 This way the channel founder can regain the channel founder
1730 privileges even it is left the channel. This works only on
1731 local server and the client must be connected to the same
1732 server to be able to regain the founder rights. Updated the
1733 protocol specs accordingly.
1735 Added support to the CMODE command in the client to set the
1736 founder auth data. Read the README to see how to set it.
1738 Added support to the CUMODE command to claim the founder
1739 rights. Read the README to see how to do it.
1741 Added support for the founder authentication to the Channel
1742 Entry in the server. Affected file silcd/idlist.h.
1744 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1745 server's CMODE command. Affected file silcd/command.c.
1747 * Added the following new functions into lib/silccore/silcauth.[ch]:
1748 silc_auth_get_method and silc_auth_get_data.
1750 * The server now saves the remote hosts public key to the
1751 SilcIDListData pointer. Affected file silcd/protocol.c.
1753 * The normal server now does not remove the channel entry from
1754 the cache if the founder authentication data is set. It used
1755 to remove it if the founder was the last one on the channel on
1756 the server and left the channel. The auth data is saved and
1757 if the channel is re-joined later the old entry is used with
1758 the old auth data. Affected files silcd/command_reply.c and
1761 * Removed the `pkcs' field from the SilcIDListData structure
1762 in the server; it is not used. Affected file silcd/idlist.h.
1764 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Fixed packet processing on slow links. Partial packets were
1767 never re-processed because the incoming data buffer was cleared
1768 by the application. Application must not directly clear the
1769 sock->inbuf, the packet processing routines handle it. Fixed
1770 this in client library and in server.
1772 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Fixed the WHOIS and IDENTIFY send reply function to really
1775 check whether to send list or just one entry. Affected file
1778 * Cleaned up the LEAVE command's channel key distribution. The
1779 affected file silcd/command.c.
1781 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1782 can enforce the channel mode as well. In that case the ID
1783 includes the ID of the server. The code now enforces the
1784 mode change if the router have different mode than the server.
1786 * The notify client operation with CMODE_CHANGE notify can now
1787 return NULL client_entry pointer if the CMODE was not changed
1788 by client. Application must check for this.
1790 * Added <Server ID> argument to INFO command to support server
1791 info fetching by Server ID.
1793 * Added silc_server_announce_get_channel_users to get assembled
1794 packets of channel users of the specified channel. Affected
1795 file silcd/server.[ch].
1797 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1798 was freed underneath the ID Cache.
1800 * Re-announce clients when the server received CHANNEL_CHANGE
1801 notify from the router. Affected file silcd/packet_send.c.
1803 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1806 crashed since it did not handle the fact that there is no cipher
1807 called "3" and didn't check the error condition. Now fixed.
1809 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1810 flag. It can be used to send message requests.
1812 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1814 * Implemented the RESTART command in the client.
1816 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1817 notice type messages. Added notice printing to the user
1820 * The channel keys are not re-generated if the channel's mode
1821 is PRIVKEY, ie private key on the channel exists. Affected
1822 files silcd/server.c and silcd/command.c.
1824 * Fixed a little bug in channel message delivery when channel
1825 private keys are set in the server. Affected file is
1826 silcd/packet_send.c.
1828 * Changed the setting on channel->on_channel = TRUE from the
1829 silc_client_save_channel_key to the JOIN command reply. The
1830 key payload is not received if the private channel key is set.
1831 Affected file lib/silcclient/command_reply.c and the
1832 lib/silcclient/client_channel.c.
1834 * When the CMODE_CHANGE notify is sent and the channel private
1835 key mode is removed the channel key must be re-generated in
1836 other cells as well. Added this support for the router in the
1837 silcd/packet_receive.c.
1839 * Added new local command NOTICE to send notice message on
1840 channel. Affected file silc/local_command.[ch].
1842 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Added new local command ME to the client. It is used to send
1845 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1846 some action. Affected file silc/local_command.[ch].
1848 * Changed channel_message and private_message client operations
1849 to deliver the message flags to the application. Added also
1850 the `flags' arguments to the silc_client_send_channel_message
1851 and silc_client_send_private_message functions. Affected file
1854 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Redefined the Private Message Payload to support private message
1857 keys and to support the new private message flags. Updated
1858 the protocol specs. Flags makes it possible to have for example
1859 CTCP style messages.
1861 * Added new type SilcPrivateMessagePayload and defined an API
1862 for it in the lib/silcclient/silcprivate.[ch].
1864 * Tested private message private keys successfully. Tested the
1865 private message key set, unset and list commands with the new
1868 * Redefined the Channel Message Payload to include the channel
1869 message flags (equal with private message flags) to support
1870 for example CTCP style messages.
1872 * Defined some of the message (for channel and private message)
1873 flags. Updated the protocol specs and added the flags to the
1874 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1876 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1878 * Added SilcKeyAgreementStatus type to the key agreement routines
1879 to indicate the current status and error if one occured.
1880 The status types are defined in the lib/silcclient/silcapi.h.
1882 * Added new local command KEY that is used to set and unset private
1883 keys for channels, set and unset private keys for private messages
1884 with remote clients and to send key agreement requests and
1885 negotiate the key agreement protocol with remote client. The
1886 key agreement is supported only to negotiate private message keys,
1887 it currently cannot be used to negotiate private keys for channels,
1888 as it is not convenient for that purpose.
1890 * Fixed a minor pending callback setting bug in the function
1891 silc_client_get_client_by_id_resolve, now the function works.
1892 Affected file lib/silcclient/idlist.c.
1894 * Added function silc_net_get_local_port to get local bound
1895 port by socket. Added to lib/silcutil/silcnet.[ch].
1897 * Added `sockets' and `sockets_count' fields to the SilcClient
1898 object. They hold the sockets of the listenning sockets in
1899 the client. Listenning sockets may be for example the key
1900 agreement server. Affected file lib/silcclient/client.[ch].
1901 Added functions the silc_client_add_socket and the
1902 silc_client_del_socket. They are exported to the application
1905 * Added ~./silc/clientkeys to support other client's public keys.
1907 * Renamed verify_server_key client operation to verify_public_key
1908 and added one argument to indicate the type of the connection
1909 (server, client etc.).
1911 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Added silc_server_connection_auth_request to handle the
1914 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1915 silcd/packet_receive.[ch].
1917 * Added silc_server_send_connection_auth_request into the
1918 silcd/packet_send.c to send the connection auth request packet.
1920 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1923 * Fixed the public key authentication in responder side in the
1924 server. The `auth_data' pointer includes the SilcPublicKey
1925 not the path to the public key. Affected file silcd/protocol.c.
1927 * Implemented the public key authentication in the initiator side
1928 in the server. Affected file silcd/protocol.c.
1930 * Removed the [RedirectClient] config section from the server
1931 configuration. Is not needed and I don't want to implement it.
1933 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Cleaned up the CMODE command in the server. It now works
1936 correctly and supports all the modes defined in the protocol.
1937 Affected file is silcd/command.c.
1939 * Added `hmac_name' field to the SilcChannelEntry in the server
1940 to hold the default HMAC of the channel. It can be set when
1941 creating the channel (with JOIN command). Affected files
1944 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1945 type to indicate the change of the current cipher and hmac
1946 on the channel. Client can safely ignore the <cipher> argument
1947 (if it chooses to do so) since the CHANNEL_KEY packet will
1948 force the channel key change anyway. The <hmac> argument is
1949 important since the client is responsible of setting the new
1950 HMAC and the hmac key into use.
1952 * Fixed the CMODE command in the client library as well.
1954 * Tested CMODE command in router environment successfully.
1956 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Show the version of the remote client (or server) when connecting
1959 to the server. It is logged to the log file. Affected file
1960 is silcd/protocol.c.
1962 * Fixed the KILLED notify handling in the client library. The
1963 client must be removed from all channels when receiving the
1966 Also, do not remove the client entry when giving the KILL
1967 command but when the KILLED notify is received.
1969 * Removed silc_idlist_find_client_by_nickname from the server.
1970 Not needed anymore. Affected files silcd/idlist.[ch].
1972 * Implemented the CHANNEL_CHANGE notify type handling to the
1973 server. Affected file silcd/server.c.
1977 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * Added silc_server_send_notify_invite to send the INVITE
1980 notify between routers.
1982 * Implemented the INVITE command correctly to the server.
1984 * Implemented the INVITE notify type handling in the server.
1986 * Implemented the INVITE command to the client library and on the
1989 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Added function silc_server_get_client_resolve to find the
1992 client entry by ID from all ID lists and then resolve it
1993 (using WHOIS) if it cannot be found. Affected file is
1996 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1998 * Implemented the BAN command to the client library.
2000 * The JOIN command in the server now checks the invite list
2003 * Changed the silc_command_reply_payload_encode_va and the
2004 silc_command_payload_encode_va to support that if argument is
2005 NULL it ignores and checks the next argument. Affected file
2006 lib/silccore/silccommand.c.
2008 * Added silc_server_send_notify_ban to send the BAN notify
2009 type between routers.
2011 * Chaned the silc_notify_payload_encode to support that if
2012 argument is NULL it ignores and checks the next argument.
2013 Affected file lib/silccore/silcnotify.c.
2015 * Tested ban lists in router environment successfully.
2017 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Implemented BAN command to the server, in silcd/command.[ch].
2021 * Removed the BAN and INVITE_LIST modes from the CMODE command
2024 * Added function silc_string_match to regex match two strings.
2025 Affected files lib/silcutil/silcutil.[ch].
2027 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Redefined parts of the SilcChannelEntry in the server to support
2030 the new ban and invite lists.
2032 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Redefined the INVITE command. The same command can be used to
2035 invite individuals to the channel but also to manage the invite
2036 list of the channel (to add to and remove from the invite list).
2037 Updated the protocol specs.
2039 * Added new command SILC_COMMAND_BAN that can be used to manage
2040 the ban list of the channel. Updated the protocol specs.
2042 * Removed the channel modes: the SILC_CMODE_BAN and the
2043 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2044 in the CMODE command. The equivalent features are now available
2045 using INVITE and BAN commands. Updated the protocol specs.
2047 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2048 in the network about change in the current ban list. The notify
2049 type is not used by the client.
2051 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2052 support the invite lists.
2054 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Added new function silc_string_regexify that converts string
2057 including wildcard characters into regex string that can
2058 be used by the GNU regex library. Added into the file
2059 lib/silcutil/silcutil.[ch].
2061 Added silc_string_regex_combine to combine to regex strings
2062 into one so that they can be used as one regex string by
2063 the GNU regex library. Added into the file
2064 lib/silcutil/silcutil.[ch].
2066 Added silc_string_regex_match to match two strings. It returns
2067 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2069 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Imported GNU regex to the soruce tree into lib/contrib.
2072 Fixed some compiler warning from the regex.c.
2074 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Fixed MOTD command in the server to work in router environment.
2078 * Fixed the MOTD command in the client library to support
2079 the server argument in the command.
2081 * Added `nickname_len' argument to the silc_idlist_add_client
2082 in the server, as the `nickname' argument may be binary data
2085 * Added silc_idlist_get_channels to return all channels from
2088 * Implemented LIST command to the server. Affected file is
2091 * Implemented the LIST command to the client library and on the
2094 * Added [<user count>] argument to the LIST command reply.
2095 With private channels the user count is not shown.
2097 * Updated TODO and README.
2099 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * The client entry's data.registered must be TRUE even with
2102 global client entry on global client list. The data.registered
2103 is used to check whether the client is anymore in the network,
2104 for example with WHOWAS command so it must be valid.
2106 * Fixed the WHOWAS command in the server. It now actually works
2107 in router environment. Added function into silcd/command_reply.c
2108 silc_server_command_reply_whowas_save.
2110 * Added silc_idlist_purge function to the silcd/idlist.c
2111 to periodically purge the ID Cache.
2113 * Fixed INFO command in the server. It works now in router
2114 environment. Added <server name> argument to the INFO command
2115 reply. Updated the protocol specs.
2117 * Fixed minor bug in silc_idcache_purge to not purge if the
2118 expire value is zero.
2120 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2121 they were buggy because of the WHOWAS information.
2123 * Fixed local command MSG to handle the async resolving of
2124 the remote client properly. It used to fail the first MSG.
2125 Affected file silc/local_command.c.
2127 * Added `data_len' field to SilcIDCache context.
2129 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Update TODO. Todo in commands in the server.
2133 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2136 used by routers as broadcast packet to inform other routers
2137 about the changed user mode.
2139 Implemented the notify handling in the server. Affected file is
2140 silcd/packet_receive.c. Added the function
2141 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2143 * Added new generic Channel Payload and deprecated the New Channel
2144 Payload. The New Channel Payload is now the generic Channel
2147 * Added new argument `mode' to the silc_server_send_new_channel
2148 as it is required in the Channel Payload now.
2150 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2151 and created a new and real SilChannelPayload to represent the
2152 new generic Channel Payload. Implemented the encode/decode
2153 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2155 * Added silc_server_get_client_channel_list to return the list
2156 of channels the client has joined for WHOIS command reply.
2157 Affected file silcd/server.[ch].
2159 * Implemented the channel list sending in the WHOIS command reply
2160 in server and in the client.
2162 Implemented the channel list displaying on the user interface
2163 as well. Affected file silc/client_ops.c.
2165 * Added silc_channel_payload_parse_list to parse list of Channel
2166 Payloads. It returns SilcDList list of SilcChannelPayloads.
2167 Client for example can use this function to parse the list of
2168 channels it receives in the WHOIS command reply. The caller
2169 must free the list by calling silc_channel_payload_list_free.
2170 Affected files lib/silccore/silcchannel.[ch].
2172 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Added one new argument <user mode> to the WHOIS command reply
2175 to return the mode of the user in SILC. Updated the protocol
2178 Implemented it to the server and client.
2180 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * Fixed the mode printing on the user interface on joining.
2183 Affected file silc/client_ops.c.
2185 * Implemented the UMODE command and user modes in general to the
2186 client library and to the user interface.
2188 * Implemented the UMODE command to the server.
2190 * The server now sends UNKNOWN_COMMAND error status if client sends
2191 unknown command. Affected file silcd/command.c.
2193 * All server commands now handle the command identifier the right
2194 way when sending the command reply to the client. The client can
2195 use to identify the command replies with the identifier.
2197 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Added silc_server_get_client_route to resolve the route to
2200 the client indicated by the client ID. Affected file is
2203 * Added silc_server_relay_packet as general function to relay
2204 packet to arbitrary destination. This deprecates functions
2205 like _send_private_message_key, _relay_notify etc. Affected
2206 file is silcd/packet_send.[ch].
2208 Removed silc_server_send_key_agreement,
2209 silc_server_send_private_message_key and
2210 silc_server_packet_relay_notify functions from the file
2211 silcd/packet_send.[ch].
2215 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2216 server. Affected file silcd/packet_receive.[ch].
2218 * Implemented the KILL command to the client. Implemented the
2219 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2220 Affected files lib/silcclient/command[_reply].c and
2221 lib/silcclient/client_notify.c. Implemented the KILL notify
2222 printing in the user inteface.
2224 * Fixed a lot silc_parse_nick memory leaks from the client
2225 library in the file lib/silcclient/command.c.
2227 * Changed the silc_server_send_notify_on_channels's `sender'
2228 argument from SilcSocketConnection to SilcClientEntry to
2229 check the sender as entry and not as connection object and not
2230 to send to the client provided as argument. The affected file
2231 is silcd/packet_send.[ch].
2233 * The notify packets that are destined directly to the client used
2234 to not to be processed by the server. Now changed that and the
2235 server processes all notify packets. After relaying the packet
2236 to the client the notify packet is processed in the server.
2238 * The silc_server_free_client_data now checks whether there is
2239 pending outgoing traffic for the client and purges the data to
2240 the network before removing the client entry.
2242 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2245 an client is killed from the SILC Network. Updated the protocol
2248 Added new function silc_server_send_notify_killed to the
2249 silcd/packet_send.[ch].
2251 * Added function silc_server_packet_relay_notify to relay notify
2252 packets that are destined directly to a client. In this case
2253 the server does not process the notify packets but merely relays
2254 it to the client. Affected file silcd/packet_send.[ch].
2256 Added also silc_server_packet_process_relay_notify to check
2257 whereto relay the notify. Affected file is
2258 silcd/packet_receive.[ch].
2260 * Implemented the KILL command to the server.
2264 * Added the backup schema desgined last fall to the protocol
2265 specs for everyone to see. The specification is in the
2266 *-spec-xx.txt draft and the packet type definitions for the
2267 backup routers is in *-pp-xx.txt draft. Thusly, added also
2268 new packet type SILC_PACKET_CELL_ROUTERS.
2270 * A big security problem in the implementation discovered. The
2271 signoff of an client did not cause new channel key generation
2272 which it of course should've done. The channel keys must be
2273 always re-generated when client leaves (or signoffs) the channel.
2274 The silc_server_remove_from_channels funtion now handles
2275 the channel key re-generation.
2277 * Added `sender' argument to the silc_server_send_notify_on_channels
2278 to not to send the client provided as argument. Affected file
2279 silcd/packet_send.[ch].
2281 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Implemented OPER and SILCOPER commands into the server and
2286 * Added silc_auth_verify and silc_auth_verify_data to verify
2287 the authentication directly from the authentication payload.
2288 It supports verifying both passphrase and public key based
2289 authentication. Affected file lib/silccore/silcauth.[ch].
2291 * Added `hash' field to the SilcIDListData structure. It is the
2292 hash negotiated in the SKE protocol. Affected file is
2295 * Slight redesigning of the SilcAuthPayload handling routines.
2296 Do not send SilcPKCS but SilcPublicKey as argument.
2298 * Implemented the public key authentication support to the
2299 serverconfig. The public key is loaded from the provided path
2300 and saved as authentication data to void * pointer. Thus,
2301 changed the unsigned char *auth_data to void *auth_data;
2303 * Fixed SHUTDOWN command to send the reply before the server
2304 is shutdown. :) Affected file silcd/command.c.
2306 * Fixed fatal bug in CONNECT command. The hostname was invalid
2307 memory and server crashed. Affected file silcd/command.c.
2309 * Fixed fatal bug in CLOSE command. The server_entry became
2310 invalid but was referenced later in the command. Affected file
2313 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Fixed fatal bug in failure packet handling. Server ignored
2316 the failure and thus crashed when it came.
2320 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2323 that the command may be executed only once in (about) 2 seconds.
2324 The old SILC_CF_LAG flag is same but allows command bursts up
2325 to five before limiting.
2327 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2328 server code. Various commands now includes the CF_LAG_STRICT
2329 flag to disallow any kind of miss-use of the command.
2331 * Fixed the silc_buffer_unformat to not to allocate any data
2332 if the length of the data is zero. It used to allocate the
2333 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2335 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Changed the format of AdminConnection configuration section
2338 in the server. Added username of the admin to the format.
2339 Affected files silcd/serverconfig.[ch].
2341 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2342 to return admin configuration data by host, username and/or
2345 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Implemented WHOWAS command to the server. Added the functions:
2349 silc_server_command_whowas_parse,
2350 silc_server_command_whowas_send_reply,
2351 silc_server_command_whowas_from_client and
2352 silc_server_command_whowas_from_server
2354 * Added <Client ID> argument to the WHOWAS command reply. Updated
2355 the protocol specs accordingly.
2357 * Implemented WHOWAS command and command_reply to the client
2360 Implemented the WHOWAS printing on the user interface.
2362 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Added new argument to the WHOWAS command reply, the real name.
2365 It is an optional argument. Updated the protocol specs.
2367 * Added SilcIDCacheDestructor callback that is registered when
2368 the SilcIDCache is allocated. The callback is called when
2369 an cache entry in the ID Cache expires, or is purged from the
2370 cache. Added into lib/silccore/idcache.[ch].
2372 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2373 to destruct the client entries when the cache entry expires.
2374 Other ID Cache's in server and in the client library ignores
2377 * If the ID Cache entry's `expire' field is zero then the entry
2378 never expires. Added boolean `expire' argument to the
2379 silc_idcache_add function in the lib/silccore/idcache.[ch].
2380 If it is TRUE the default expiry value is used.
2382 * Added silc_server_free_client_data_timeout that is registered
2383 when client disconnects. By default for 5 minutes we preserve
2384 the client entry for history - for WHOWAS command.
2386 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Added support to the server to enforce that commands are not
2389 executed more than once in 2 seconds. If server receives
2390 commands from client more frequently, timeout is registered
2391 to process the commands. Affected file silcd/command.c.
2392 Added new function silc_server_command_process_timeout.
2394 * Changed NICK_NOTIFY handling in client library to check that
2395 if the client's nickname was changed, so there is no need to
2396 resolve anything from the server.
2398 * Removed error printing from the WHOIS and IDENTIFY commands.
2399 If error occurs then it is ignored silently in the client library.
2400 The application, however, may map the received error to
2401 human readable error string. The application currently maps
2402 the NO_SUCH_NICKNAME error to string.
2404 * Made the command status message public to the application. Moved
2405 them from lib/silcclient/command_reply.c to
2406 lib/silcclient/command_reply.h. The application can map the
2407 received command status to the string with the
2408 silc_client_command_status_message function.
2410 * Added check to the server to check that client's ID is same
2411 as the Source ID in the packet the client sent. They must
2414 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added dist-bzip hook to the Makefile.am to make bzip2
2417 compressed distributions.
2419 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Server now enforces the maximum length for the nickname and
2422 the channel as protocol specification dictates. 128 bytes for
2423 nickname and 256 bytes for channel name.
2425 * Moved the WHOIS printing to the application. The client libary
2426 does not print out the WHOIS information anymore, the application
2427 must do it. Renamed silc_client_command_reply_whois_print to
2428 the silc_client_command_reply_whois_save.
2430 The client's idle time is also sent to the application now, and
2431 the idle is shown on screen.
2433 * Added silc_client_command_reply_identify_save to save the
2434 received IDENTIFY entries.
2436 * Do not check for channel private keys in message sending and
2437 reception if the channel does not have the PRIVKEY mode set.
2438 Affected file lib/silclient/client_channel.c.
2440 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2443 just surfaced after chaning the JOIN procedure.
2445 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * Added silc_client_get_clients_by_list to get client entries
2448 from Client ID list, that is returned for example by JOIN
2449 and USERS command replies. The application should use this
2450 function for example when JOIN command reply is received to
2451 resolve the clients already on the channel (library does not
2452 do that anymore as USERS command reply is not used in the JOIN
2453 procedure anymore). Affected files lib/silcclient/silcapi.h and
2454 lib/silcclient/idlist.c.
2456 * JOIN command reply and USERS command reply returns now SilcBuffer
2457 pointers instead of unsigned char pointers when returning
2458 the client list and mode list.
2460 * Added <Client ID> argument to the JOIN command reply, mainly
2461 for the server to identify for which client the command was
2462 originally sent. Updated protocol specs accordingly.
2464 * Added SilcDlist private_key pointer to the SilcChannelEntry
2465 in the client to support the channel private keys. Affected
2466 file is lib/silcclient/idlist.h.
2468 * Added SilcChannelPrivateKey argument to the function
2469 silc_client_send_channel_message so that application can choose
2470 to use specific private ke if it wants to. If it is not provided,
2471 the normal channel key is used, unless private keys are set.
2472 In this case the first (key that was added first) is used
2473 as the encryption key.
2475 * Implemented the support for channel private key handling.
2476 Implemented the following functions:
2478 silc_client_add_channel_private_key,
2479 silc_client_del_channel_private_keys,
2480 silc_client_del_channel_private_key,
2481 silc_client_list_channel_private_keys and
2482 silc_client_free_channel_private_keys
2484 Affected file lib/silcclient/client_channel.c.
2486 * Added the support for the private keys in the channel message
2487 sending and encryption and in the message reception and
2488 decryption. Affected funtions are
2489 silc_client_send_channel_message and silc_client_channel_message.
2491 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Added SKE's key verify callback to the client library's
2494 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2496 * Removed the statement that server (or router) must send USERS
2497 command reply when joining to the channel so that the client
2498 knows who are on the channel. Instead, the client list and
2499 client's mode list is now sent in the JOIN command reply to the
2500 client who joined channel. This is better solution.
2502 * Added function silc_server_get_users_on_channel and function
2503 silc_server_save_users_on_channel to the silcd/server.[ch].
2505 * Removed function silc_server_command_send_users from the
2508 * Do not show topic on the client library anymore. The topic is
2509 sent in the command reply notify to the application and the
2510 application must show the topic now.
2512 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added client searching by nickname hash into the IDENTIFY and
2515 WHOIS commands in the server as they were clearly missing from
2516 them. Affected file is silcd/command.c.
2518 * Fixed a bug in private message receiving in the client library.
2519 The remote ID was freed and it wasn't supposed, now it is
2522 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Minor fix to the channel payload; allocate the data area, as it
2525 needs to be of specific length.
2527 * If the key agreement port is zero then the operating
2528 system will define the bound port. Affected files are
2529 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2531 * Added new function silc_channel_payload_decrypt into the file
2532 lib/silccore/silcchannel.[ch].
2534 * Moved the channel message etc, check from silc_packet_decrypt
2535 to applications. The library calls now a generic
2536 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2537 when the packet is either normal or special. This was done to
2538 allow more wide range of checking that was not allowed when
2539 the code was in library. Now applications can do virtually any
2540 checks to the packet and return to the library the decision how
2541 the packet should be processed. Affected files are
2542 lib/silccore/silcpacket.[ch].
2544 Added silc_server_packet_decrypt_check to the server and
2545 silc_client_packet_decrypt_check to the client library.
2547 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2548 to send with specified source and destination information.
2550 * Channel message delivery between routers was broken after the
2551 channel key distribution was fixed earlier. The channel key
2552 was used be to distributed to other routers as well which is not
2553 allowed by the protocol. Now this is fixed and channel keys
2554 really are cell specific and the channel message delivery between
2555 routers comply with the protocol specification.
2557 * Fixed various commands in server to check also the global list
2558 for the channel entry and not just the local list. The affected
2559 file silcd/command.c.
2561 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Added assert()s to buffer formatting and unformatting routines
2564 to assert (if --enable-debug) when error occurs. Affected
2565 file: lib/silcutil/silcbuffmt.c.
2567 * Changed to auto-reconnect to check whether the remote host is
2568 router and register the re-connect timeout if it is. It used
2569 to check that whether we are normal server, but router must do
2570 auto-reconnect with another router as well. Affected file
2573 * Removed the [<key len>] option from CMODE command as the cipher
2574 name decides the key length, nowadays. See the defined ciphers
2575 from the protocol specification.
2577 * Added [<hmac>] option to the CMODE command to define the HMAC
2578 for the channel. Added SILC_CMODE_HMAC channel mode.
2580 * Added [<hmac>] option for the JOIN command so that user can
2581 select which HMAC is used to compute the MACs of the channel
2584 * Added Hmac field to the Channel Message Payload. The integrity
2585 of plaintext channel messages are now protected by computing
2586 MAC of the message and attaching the MAC to the payload. The
2587 MAC is encrypted. Now, it is clear that this causes some
2588 overhead to the size of the packet but rationale for this is that
2589 now the receiver can verify whether the channel message decrypted
2590 correctly and also when private keys are set for the channel the
2591 receiver can decrypt the packet with several keys and check from
2592 the MAC which key decrypted the message correctly.
2594 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2595 lib/silccrypt/silccipher.[ch].
2597 * Added silc_hash_len to return the digest length into the
2598 lib/silcrypt/silchash.[ch].
2600 * Rewrote parts of Silc Channel Payload interface in the
2601 lib/silccore/silcchannel.[ch]. The encode function now also
2602 encrypts the packet and parse function decrypts it.
2604 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Fixed a minor formatting bug in the SKE's key material processing.
2607 It actually might have processed the keys wrong way resulting
2610 * Redefined the mandatory HMAC algorithms and added new algorithms.
2611 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2612 and hmac-md5 truncated to 96 bits. The mandatory is now
2613 hmac-sha1-96. Rest are optional (including the one that used
2614 to be mandatory). Rationale for this is that the truncated HMAC
2615 length is sufficient from security point of view and can actually
2616 make the attack against the HMAC harder. Also, the truncated
2617 HMAC causes less overhead to the packets. See the RFC2104 for
2620 * Added new [hmac] configuration section. The SKE used to use
2621 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2622 is of course wrong. The official names that must be proposed in
2623 the SKE are the ones defined in the protocol specification
2624 (hmac-sha1-96 for example). The user can configure any hmac
2625 using any hash function configured in the [hash] section. At
2626 least, the mandatory must be configured.
2628 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2630 * Added HMAC list to the SKE proposal list. It has now both
2631 hash algorithm list and HMAC list. This makes the protocol
2632 incompatible with previous versions. The SKE now seems to work
2633 the way it is supposed to work, for the first time actually.
2635 * Defined plain Hash algorithms to the protocol specification.
2638 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2640 * Implemented support for key agreement packets into the server.
2641 Added functions silc_server_key_agreement and
2642 silc_server_send_key_agreement. Other than these functions,
2643 server has nothing to do with this packet.
2645 * Added support for private message key packets into the server.
2646 Added functions silc_server_private_message_key and
2647 silc_server_send_private_message_key.
2651 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2652 called in the protocol's final callback instead in the END
2653 protocol state. This makes a little more sense and in the same
2654 time in client we can use the same protocol routines for normal
2655 key exchange and to key agreement packet handling as well.
2657 * Added to both client's and server's KE protocol context the
2658 SilcSKEKeyMaterial pointer to save the key material. We will
2659 bring the key material to the protocol's final callback by doing
2660 this. The final callback must free the key material.
2662 * Added SKE's packet_send callback into client's KE protocol
2663 context so that the caller can choose what packet sending function
2664 is used. This way we can use different packet sending when
2665 doing normal SKE when doing key agreement packet handling (in
2666 the key agreement packet handling we do not want to encrypt
2669 * Implemented the responder side of the key agreement routines
2670 in the client. The client can now bind to specified port and
2671 accept incoming key negotiation. The key material is passed
2672 to the application after the protocol is over.
2674 * Implemented the processing of incoming Key Agreement packet
2675 in the client. Added function silc_client_key_agreement to
2678 * Implemented the intiator side of the key agreement routines
2679 in the client. The client can now initiate key agreement with
2680 another remote client. The key material is passed to the
2681 application after the protocol is over.
2683 * Created client_keyagr.c to include all the key agreement
2686 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2687 SILC_TASK_CALLBACK except that it is not static.
2689 * Created client_notify.c and moved the Notify packet handling
2690 from the client.[ch] into that file.
2692 * Created client_prvmsg.c and moved all private message and
2693 private message key routines from the client.[ch] into that file.
2695 * Create client_channel.c and moved all channel message and
2696 channel private key routines from the client.[ch] into that file.
2698 * Changed silc_client_get_client_by_id_resolve to resolve with
2699 WHOIS command instead of IDENTIFY command, in the file
2700 lib/silclient/idlist.c.
2702 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Implemented the SKE's responder side to the Client library.
2706 * When FAILURE is received to the protocol do not trust it
2707 blindly. Register a timeout to wait whether the remote closes
2708 the connection as it should do it, only after that process the
2709 actual failure. This was changed to both client and server.
2711 * Added client_internal.h to include some of the structures
2712 there instead of client.h in lib/silcclient/.
2714 * Added function silc_task_unregister_by_callback to unregister
2715 timeouts by the callback function.
2717 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Some "Incomplete WHOIS info" errors has been appearing on the
2720 log files. Took away the entry->userinfo check from WHOIS
2721 reply sending. The entry->userinfo is now " " if client did not
2722 provide one. I thought this was fixed earlier but something
2723 is wrong still. Let's see if the error still appears.
2725 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Fixed a minor bug in the login when the channel key is
2728 re-generated in the server. It used to generate the key in
2729 wrong order and thus caused problems in the channel traffic.
2731 * Fixed a minor bug in channel key distsribution after
2732 KICK command. The key was not sent to the router even though
2735 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Added silc_ske_process_key_material_data as generic routine
2738 to process any key material as the SILC protocol dictates. The
2739 function is used by the actual SKE library but can be used by
2740 applications as well. This relates to the private message keys
2741 and the channel private keys since they must be processed the
2742 same way the normal SILC session keys. The protocol dictates
2743 this. Affected files: lib/silcske/silcske.[ch].
2745 Added also silc_ske_free_key_material to free the
2746 SilcSKEKeyMaterial structure.
2748 * Defined silc_cipher_set_key function to set the key for
2749 cipher without using the object's method function. The affected
2750 files: lib/silccrypt/silccipher.[ch].
2752 * Implemented silc silc_client_add_private_message_key,
2753 silc_client_add_private_message_key_ske,
2754 silc_client_del_private_message_key,
2755 silc_client_list_private_message_keys and
2756 silc_client_free_private_message_keys functions in the
2759 Added functions silc_client_send_private_message_key to send
2760 the Private Message Key payload and silc_client_private_message_key
2761 to handle incoming Private Message Key payload.
2763 * Added Cipher field to the Private Message Key payload to set
2764 the cipher to be used. If ignored, the default cipher defined
2765 in the SILC protocol (aes-256-cbc) is used.
2767 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Removed lib/silcclient/ops.h file.
2771 Redefined parts of the SILC Client Library API. Created new
2772 file silcapi.h that deprecates the ops.h file and defines the
2773 published Client Library API. Defined also private message key
2774 API and channel private key API into the file.
2776 This is the file that the application must include from the
2777 SILC Client Library. Other files need not be included by
2778 the application anymore.
2780 * Added new key_agreement client operation callback and also
2781 defined the Key Agreement library API for the application.
2783 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2786 is used by clients to request key negotiation between another
2787 client in the SILC network. If the negotiation is started it
2788 is performed using the SKE protocol. The result of the
2789 negotiation, the secret key material, can be used for example
2790 as private message key.
2792 Implemented the Key Agreement payload into the files
2793 lib/silccore/silauth.[ch].
2795 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Redefined ciphers for the SILC protocol. Added some new ciphers
2798 and defined the key lengths for the algorithms. Changed the
2799 code accordingly. The default key length is now 256 bits.
2801 * Fixed SKE key distribution function silc_ske_process_key_material
2802 when the key length is more than 128 bits. The default key
2803 length in SILC is now 256 bits.
2805 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2806 to indicate unsupported algorithm.
2808 * Renamed rijndael.c to aes.c and all functions as well.
2810 * Fixed a long standing channel key setting bug in client library.
2811 Weird that it has never surfaced before.
2813 * Fixed bug in channel deletion. If the entire channel is removed
2814 then it must also delete the references of the channel entry
2815 from the client's channel list as the client's channel entry and
2816 the channel's client entry share same memory.
2818 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2820 * Implemented CONNECT and SHUTDOWN commands in the client.
2822 * Implemented CLOSE command to the client.
2824 * Added the function silc_idlist_find_server_by_name into the
2825 files silcd/idlist.[ch].
2827 Added the function silc_idlist_find_server_by_conn into the
2828 files silcd/idlist.[ch].
2830 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * DIE command was renamed to SHUTDOWN. Updated the both code
2835 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2836 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2838 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2841 * Added function silc_server_create_connection function to create
2842 connection to remote router. My server implementation actually
2843 does not allow router to connect to normal server (it expects
2844 that normal server always initiates the connection to the router)
2845 so the CONNECT command is only good for connecting to another
2848 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2851 or some other client was kicked from the channel.
2853 Implemented the handling of the notify type to both client
2856 Implemented silc_server_send_notify_kicked to send the KICKED
2857 notify. It is used to send it to the server's primary router.
2859 * Implemented the KICK command into server and client.
2861 * Added `query' argument to the silc_idlist_get_client function
2862 to indicate whether to query the client from server or not if
2865 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2866 to indicate that the client is not channel founder.
2870 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Removed the rng context from SilcPacketContext structure and
2873 changed that the packet routine uses the Global RNG API.
2875 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Added support for quit message that client can "leave" on the
2878 channel when it quits the SILC. It is ditributed inside the
2879 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2881 Added silc_server_free_client_data that will take the
2882 signoff message as argument.
2884 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2886 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Updated parts of the protocol specification to keep it up
2891 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2894 payloads in one packet.
2896 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2897 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2898 use now the new List flag.
2900 * Also deprecated the following packet types: REPLACE_ID,
2901 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2903 * Added list support for Notify packet in server.
2905 * Added silc_server_send_notify_channel_change to send the
2906 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2907 the silc_server_send_replace_id.
2909 * Added silc_server_send_notify_nick_change to send the
2910 NICK_CHANGE notify type. Deprecates the function
2911 silc_server_send_replace_id.
2913 * Added silc_server_send_notify_join to send the JOIN notify type.
2914 Deprecates the function silc_server_send_new_channel_user.
2916 * Added silc_server_send_notify_leave to send LEAVE notify type.
2917 Deprecates the function silc_server_send_remove_channel_user.
2919 * Added silc_server_send_notify_cmode and
2920 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2921 types. Deprecates the silc_server_send_set_mode function.
2923 * Added SERVER_SIGNOFF notify type to indicate that server has
2924 quit. This means that all clients on the channel from that
2925 server will drop. This can be also used when netsplit happens.
2927 Deprecated REMOVE_ID packet type since it is not needed anymore
2930 Added silc_server_send_notify_server_signoff to send the
2931 SERVER_SIGNOFF notify type. Deprecates the function
2932 silc_server_send_remove_id.
2934 Added also silc_server_send_notify_signoff to send the
2935 SIGNOFF notify type.
2937 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2938 SILC protocol from this day on. Changed the protocol
2939 specification as well.
2941 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2942 notify type. It is used between routers to notify about
2943 topic changes on a channel.
2945 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2948 * Partly updated the protocol specification to comply with the
2949 changes now made. It is still though a bit outdated.
2951 * The JOIN notify type now takes one extra argument <Channel ID>.
2952 The packet used to be destined to the channel but now the
2953 JOIN type may be sent as list thus it is impossible to
2954 destine it to any specific channel. By adding this argument
2955 it is again possible.
2957 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added CREDITS file. The CHANGES and CREDITS file will appear
2960 in the distribution as well.
2962 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2965 types in the server's silcd/packet_receive.c.
2967 * Implemented CMODE and CUMODE to work in router environment.
2969 * Fixed minor encoding and decoding buglet from the
2970 lib/silccore/silcmode.c.
2972 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2975 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2977 * Changed all SilcConfigServer* and silc_config_server* to
2978 SilcServerConfig* and silc_server_config*, respectively.
2981 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Associated the ID (client or server ID) to the Authentication
2984 Payload to avoid any possibility of forging. Updated the
2985 protocol specification and the code accordingly.
2987 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * The RSA key length is now save to the RsaKey context in the
2990 key generation process in lib/silccrypt/rsa.c. The key length
2991 is now used to figure out the maximum size of the block allowed
2992 to be encrypted/signed.
2994 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2995 is equivalent to the silc_mp_mp2bin but does not allocate any
2998 * Changed silc_mp_mp2bin API to take length argument. If it is
2999 non-zero then the buffer is allocated that large. If zero, then
3000 the size is approximated using silc_mp_sizeinbase, which however
3003 * Created Global RNG API which is global RNG that application can
3004 initialize. After initializing, any routine anywhere in the
3005 code (including library) can use RNG without allocating a new
3006 RNG object. This was done to allow this sort of use of the
3007 RNG in code that has no chance to allocate RNG object. All
3008 applications currently allocate this and many routines in the
3009 library use this. Affected file lib/silccrypt/silcrng.[ch].
3011 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3012 it to use the Global RNG API.
3014 * Defined Authentication Payload into protocol specification that
3015 is used during SILC session to authenticate entities. It is
3016 used for example by client to authenticate itself to the server
3017 to obtain server operator privileges.
3019 Implemented this payload into the lib/silccore/silcauth.[ch].
3020 Implemented also routines for public key based authentication
3021 as the new protocol specification dictates.
3023 Moved definitions of different authentication methods from
3024 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3026 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3027 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3028 silc_pkcs_verify_with_hash functions into the file
3029 lib/silccrypt/silcpkcs.[ch].
3031 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * The client entry's userinfo pointer must be always valid.
3034 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3035 will fail since it requires the userinfo. Now, the userinfo
3036 is allocated as "" if actual userinfo does not exist. Actually,
3037 it must exist and it is totally Ok to drop client connections
3038 that does not announce the userinfo. However, we will make
3039 this workaround for now.
3041 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3042 to return the remote port by socket.
3044 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3047 SILC_SERVER_PENDING_EXEC and added an new macro
3048 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3049 data or when error occurs while processing the pending command.
3051 Added new argument `destructor' into silc_server_command_pending
3052 and to the SilcServerCommandPending object. This destructor is
3053 now called after calling the pending callback or if error occurs
3054 immediately. If error occurs the actual pending callback won't
3055 be called at all - only the destructor. The destructor may be
3056 NULL if destructor is not needed.
3058 All this applies for client library code as well. Similar
3059 changes were made there as well for the pending commands.
3061 In the client, the application must now allocate the
3062 SilcClientCommandContext with the silc_client_command_alloc
3065 * Added reference counter to the SilcServerCommandContext. Added
3066 function silc_server_command_alloc and silc_server_command_dup
3069 Same type of functions added to the client library for the same
3072 * Removed the cmd_ident from IDListData away since it is now
3073 global for all connections. It is the command identifier used
3074 in command sending and with pending commands. The affected file
3077 * Added reference counter to the SilcSocketConnection objecet to
3078 indicate the usage count of the object. The object won't be
3079 freed untill the reference counter hits zero. Currently only
3080 server uses this, and client ignores it. The client must be
3081 set to use this too later. The affected files are
3082 lib/silccore/silcsockconn.[ch]. Added also the function
3083 silc_socket_dup to increase the reference counter.
3085 This was mainly added because it is possible that the socket
3086 is removed underneath of pending command or other async
3087 operation. Now it won't be free'd and proper DISCONNECTING
3088 flags, etc. can be set to avoid sending data to connection that
3089 is not valid anymore.
3091 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3092 the connection. After that it sets SILC_SET_DISCONNECTED.
3093 It is, however, possible that the socket data is not still freed.
3094 The silc_server_packet_process now checks that data is not
3095 read or written to connection that is DISCONNECTED. The socket
3096 get's freed when the reference counter hits zero.
3098 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3100 * Changed the client operation API: channel_message operation's
3101 `sender' is now the client entry of the sender, not the nickname
3102 and the `channel' is the channel entry, not the channel name.
3104 In the private_message operation the `sender' is now also the
3105 client entry of the sender not the nickname.
3107 Affected file is lib/silcclient/ops.h and all applications
3108 using the client operations.
3110 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Moved the calling of ops->connect() from connect_to_server_final
3113 into receive_new_id functin since that is the point when the
3114 client is actually allowed to send traffic to network. The
3115 affected file is lib/silcclient/client.c.
3117 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3120 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3121 (if needs broadcasting) instead of broadcasting the packets one
3122 by one which would make a burst in the network traffic.
3124 * Added `broadcast' argument to the functions in silcd/server.[ch]
3125 silc_server_create_new_channel[_with_id] to indicate whether
3126 to send New Channel packet to primary router.
3128 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Added new function into the silcd/server.[ch] files:
3131 silc_server_create_new_channel_with_id to create new channel with
3132 already existing Channel ID.
3134 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3135 lib/silccore/silcpacket.h. This packet is used t send list of
3136 Set Mode payloads inside one packet. Server uses this to set
3137 the modes for the channels and clients on those channels, that it
3138 announced to the router when it connected to it. The protocol
3139 specification has been updated accordingly.
3141 * The silc_server_new_channel did not handle the packet coming
3142 from normal server as it normally does not send that. However,
3143 when it announces its channels it does send it. Implemented
3144 the support for that.
3146 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3147 into the file lib/silccore/id.h.
3149 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Fixed memory leaks in the functions silc_idlist_del_client,
3152 silc_idlist_del_channel and silc_idlist_del_server in the file
3153 silcd/idlist.c. All of those leaked like a sieve.
3155 * Fixed some small memory leaks in the client's function
3156 silc_client_notify_by_server.
3158 * Added functions into silcd/server.c: silc_server_announce_clients,
3159 silc_server_announce_channels and silc_server_announce_server.
3160 These functions are used by normal and router server to announce
3161 to its primary router about clients, channels and servers (when
3162 router) that we own. This is done after we've connected to the
3165 These functions effectively implements the following packet types:
3166 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3167 and SILC_PACKET_NEW_ID_LIST.
3169 * Added new functions into the silcd/packet_receive.[ch]:
3170 silc_server_new_id_list, silc_server_new_channel_list and
3171 silc_server_new_channel_user_list to handle the incoming
3172 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3174 * Added support of changing Channel ID in the function
3175 silc_server_replace_id. If the server that announces a channel
3176 to the router already exists in the router (with same name but
3177 with different Channel ID), router is responsible to send
3178 Replace ID packet to the server and force the server to change
3179 the Channel ID to the one router has.
3181 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3182 client that the Channel ID has been changed by the router. The
3183 normal server sends this to the client. Client must start using
3184 the new Channel ID as the channel's ID.
3186 Implemented handling of this new type into lib/silcclient/client.c
3187 into the function silc_client_notify_by_server.
3189 * Added new function silc_idlist_replace_channel_id into the files
3190 silcd/idlist.[ch] to replace the Channel ID.
3192 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Call silc_server_command_identify_check always when processing
3195 the IDENTIFY command in silcd/command.c
3197 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3200 send keepalive packets. The packet can be sent by clients,
3201 servers and routers.
3203 Added function silc_socket_set_heartbeat into the file
3204 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3205 If not set, the heartbeat is not performed. The actual
3206 heartbeat is implemented in the low level socket connection
3207 library. However, application is responsible of actually
3210 Added silc_server_send_heartbeat to send the actual heartbeat
3211 packet into silcd/packet_send.[ch]. Server now performs
3212 keepalive with all connections.
3214 * Added silc_task_get_first function into lib/silcutil/silctask.c
3215 to return the timeout task with shortest timeout. There was a bug
3216 in task unregistration that caused problems. TODO has been
3217 updated to include that task system must be rewritten.
3219 * The client library will now resolve the client information when
3220 receiving JOIN notify from server for client that we know but
3221 have incomplete information.
3223 * Rewrote parts of silc_server_remove_from_channels and
3224 silc_server_remove_from_one_channel as they did not remove the
3225 channel in some circumstances even though they should've.
3227 * Encryption problem encountered in server:
3229 The LEAVE command used to send the Channel Key packet to the
3230 router immediately after generating it. However, the code
3231 had earlier sent Remove Channel user packet but not immediately,
3232 ie. it was put to queue. The order of packets in the router
3233 was that Channel Key packet was first and Remove Channel User
3234 packet was second, even though they were encrypted in the
3235 reverse order. For this reason, MAC check failed. Now, this
3236 is fixed by not sending the Channel Key packet immediately but
3237 putting it to queue. However, this is more fundamental problem:
3238 packets that are in queue should actually not be encrypted
3239 because packets that are sent immediately gets encrypted
3240 actually with wrong IV (and thus MAC check fails). So, packets
3241 that are in queue should be encrypted when they are sent to
3242 the wire and not when they put to the queue.
3244 However, the problem is that the current system has not been
3245 designed to work that way. Instead, the packet is encrypted
3246 as soon as possible and left to the queue. The queue is then
3247 just purged into wire. There won't be any fixes for this
3248 any time soon. So, the current semantic for packet sending
3251 o If you send packet to remote host and do not force the send
3252 (the packet will be in queue) then all subsequent packets to the
3253 same remote host must also be put to the queue. Only after the
3254 queue has been purged is it safe again to force the packet
3257 o If you send all packets immediately then it safe to send
3258 any of subsequent packets through the queue, however, after
3259 the first packet is put to queue then any subsequent packets
3260 must also be put to the queue.
3262 Follow these rules and everything works fine.
3264 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Added new function silc_server_remove_clients_by_server to
3267 remove all client entries from ID list when the server connection
3268 is lost. In this case it is also important to invalidate all
3269 client entires as they hold the invalid server entry. This
3270 fixes fatal bug when server has lost connection and will reconnect
3273 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Made some sanity checks to silc_server_daemonise like to check
3276 whether the requested user and group actually exists.
3278 * Added sanity check to SKE's silc_ske_responder_finish to check
3279 that the public and private key actually is valid.
3281 * Invalidate the client's nickname when receiving Replace ID
3282 packet and the Client ID is being replaced. This means that the
3283 server will query the nickname if someone needs it (client)
3286 * Sort the ID Cache in client library when the ID Cache data
3287 has changed (needs sorting).
3289 * Do not allow for SILC client to create several connections to
3290 several servers. The client does not support windows right now
3291 and generating multiple connections causes weird behaviour.
3293 Irssi-silc client does support windows and can handle several
3294 connections without problems, see: www.irssi.org and SILC plugin.
3296 * Fixed some places where client was added to the IDList. The
3297 rule of thumb is following (in order to get everything right):
3298 If the client is directly connected local client then the
3299 `connection' argument must be set and `router' argument must be
3300 NULL to silc_idlist_add_client function. If the client is not
3301 directly connected client then the `router' argument must
3302 bet set and the `connection' argument must be NULL to the
3303 silc_idlist_add_client function.
3305 * The funtion silc_server_packet_send_local_channel actually did
3306 not check whether the client was locally connected or not. It
3307 does that now. Fixed a bug related to LEAVE command.
3309 * Fixed Remove Channel User payload parsing bug in server's
3310 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3312 * The server's silc_server_save_channel_key now checks also the
3313 global ID list for the channel as it might not be in the local
3314 list. Fixed a bug related to LEAVE command.
3316 * Is this the end of the [<unknown>] buglet that has been lurking
3317 around for a long time? A little for loop fix in server's
3318 silc_server_command_whois_parse that is used by both IDENTIFY
3319 and WHOIS command. At least, this was a clear bug and a cause
3320 of one type of [<unknown>] buglet.
3322 * WHOIS and IDENTIFY commands call the function
3323 silc_server_command_[whois/identify]_check function even if
3324 we are not router server.
3326 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Added --with-gmp configuration option. If set the GMP
3329 is always compiled in the SILC source tree. If not set then
3330 it is checked whether the system has the GMP3 installed. If
3331 it has then the GMP won't be compiled (the system's headers
3332 and library is used), if it doesn't have it then the GMP is
3333 compiled in the SILC source tree.
3335 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Changed RSA private exponent generation to what PKCS #1
3338 suggests. We try to find the smallest possible d by doing
3339 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3340 not security fix but optimization.
3342 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Added new config entry [Identity] to fork the server and run
3345 it as specific user and group. A patch from Bostik.
3347 * Imported Dotconf configuration library into lib/dotconf.
3348 This will be used to create the SILC configuration files later.
3349 It will appear in the distsribution after this commit.
3351 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * A big code auditing weekend happening. Auditing code for
3354 obvious mistakes, bugs and errors. Also, removing any code
3357 Removed files for being obsolete:
3359 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3360 inline in the file lib/silcutil/silcbuffer.h)
3362 o lib/silcutil/silcbufutil.c (the header has inline versions)
3364 Changed code to fix possible error conditions:
3366 o The buffer formatting routines now check that the destination
3367 buffer really has enough space to add the data. This applies for
3368 both buffer formatting and unformatting
3369 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3370 unformatting was changed to accomodate following rules:
3371 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3372 sent to the function while XXX_*STRING will not allocate or copy
3373 the data into the buffer. Instead it sets the pointer from the
3374 buffer into the pointer sent as argument (XXX_*STRING used to
3375 require that the pointer must be allocated already). This change
3376 makes this whole thing a bit more consistent and more optimized
3377 (note that the data returned in the unformatting with XXX_*STRING
3378 must not be freed now). The routines return now -1 on error.
3380 o Tried to find all code that use buffer_format and buffer_unformat
3381 and added return value checking to prevent formatting and
3382 especially unformatting errors and possible subsequent fatal
3385 o Changed ske->x and ske->KEY to mallocated pointers in
3386 lib/silcske/silcske.h. Fixed possible data and memory leak.
3388 o Added return value checking to all *_parse* functions. Fixed
3389 many memory leaks as well.
3391 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3392 so that buffer overflows would not happen. All code now also
3393 checks the return value as it can fail.
3395 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Added reconnection support to server if the normal server looses
3398 its connection to the router (for example if router is rebooted).
3399 The server performs normal reconnection strategy implemented
3400 to the server. Affected file silcd/server.c.
3402 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Added new packet type SILC_PACKET_SET_MODE that is used to
3405 distribute the information about changed modes (for clients,
3406 channels and clients channel modes) to all routers in the
3407 network. Updated the protocol specification accordingly.
3409 Added functions into silcd/packet_send.c and
3410 silcd/packet_receive.c: silc_server_send_set_mode,
3411 silc_server_set_mode.
3413 Added new files silcmode.[ch] into lib/silccore that implements
3414 the encoding and decoding of Set Mode Payload. Added new type
3415 SilcSetModePayload. Moved the definitions of different modes
3416 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3418 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Oops, a little mistake in server's connection authentication
3421 protocol. The protocol is not ended with FAILURE but with
3422 SUCCESS if the authentication is Ok. :) Affected file is
3425 * Implemented NICK_CHANGE notify handling in server in the file
3426 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3427 the local clients on the channel. After the changing nickname
3428 in router environment snhould work and the [<unknown>] nickname
3429 should appear no more.
3431 The silc_server_replace_id function that receives the Replace ID
3432 payload now sends the NICK_CHANGE notify type also in the file
3433 silcd/packet_receive.c
3435 * Changed WHOIS and IDENTIFY command to support the maximum amount
3436 of arguments defined in protocol specs (3328 arguments). This
3437 fixed a bug that caused problems when there were more than three
3440 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Added extra parameter, command identifier, to the
3443 silc_client_send_command so that explicit command identifier
3446 Changed that ID list routines uses specific command identifier
3447 when sending WHOIS/IDENTIFY requests to the server so that they
3448 can be identified when the reply comes back.
3450 Affected files lib/silcclient/command.[ch],
3451 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3453 * Added `sender' argument to silc_server_packet_send_to_channel
3454 to indicaet the sender who originally sent the packet to us
3455 that we are now re-sending. Ignored if NULL. Affected file
3456 silcd/packet_send.[ch].
3458 * Added some server statistics support in silcd/server_internal.h
3459 SilcServerStatistics structure and around the server code. Also
3460 send some nice statistics information when client is connecting
3463 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Fixed channel ID decoding in server's JOIN command reply in
3466 silcd/command_reply.c
3468 * Fixed braodcasting of replace ID payload to not to send it if
3469 we are standalone server in silcd/packet_receive.c.
3471 * Fixed all channel message sending routines to not to send
3472 packets to clients that has router set, since they are routed
3473 separately in the same function earlier. Affects file
3474 silcd/packet_send.c and all channel packet sending functions.
3476 * In USERS reply, res_argv[i] are not allocated, the table
3477 is allocated. Thus changed that free the table, not its
3480 * In server's whois_check and identify_check if the client is
3481 locally connected do not send any WHOIS commands - they are not
3484 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed some minor bugs in client when sending WHOIS command. The
3487 arguments was in wrong order.
3489 * Removed statis function add_to_channel from server in
3490 silcd/command.c that was previously used with the joining but
3493 * Tested USERS command in router environment successfully with two
3494 routers, two servers and two clients.
3496 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Reorganized the USERS command and command reply in client library
3499 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3500 When the command is given by user we register a pending command
3501 callback that will reprocess the command after the reply has been
3502 received from the server. When reprocessing the packet we then
3503 display the information. Thus, the USERS information is displayed
3504 now in the command callback instead of in the command reply
3505 callback. The processing of the command is same as previously
3506 when server has sent the command reply in the JOINing process.
3508 * Added to USERS command in silcd/command_reply.c to join the client,
3509 we didn't use to know about, to the channel after we've created
3510 a client entry for it. Also, for clienet we did know already still
3511 check whether it is on the channel or not and add it if not.
3513 * Removed silc_server_command_join_notify as the function and its
3516 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Changed the client's pending command handling to the same as the
3519 server's pending command handling. It is also now possible to
3520 execute command reply functions from other command reply
3521 function as the function callbacks for commands and command
3522 replies are one and same. The pending commands are not static
3523 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3524 in client connection context. Thus, pending commands are server
3525 connection specific as it is convenient.
3527 Changed the function silc_client_command_pending and
3528 silc_client_command_pending_del and added new function
3529 silc_client_command_pending_check. Removed the
3530 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3533 * Added cmd_ident, current command identifier, to the client
3534 connection context in lib/silcclient/client.h to keep track on
3535 command identifiers used in command sending. Client's command reply
3536 function handling now supports the mandatory command identifiers.
3538 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3539 funtions in client to fully support pending command callbacks.
3541 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3542 as one of the arguments to the application in the command reply
3545 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3546 before first releasing SILC but came back. Now it is removed again
3547 and should come back nomore. The FORWARDED flag was used only
3548 by the JOINing procedure by forwarding the command packet to router.
3549 Now, the JOINing procedure has been changed to more generic (due
3550 to various router environment issues) and FORWARDED is not needed
3551 anymore for anything. The protocol specification is yet to be
3554 Now, removed silc_server_packet_forward from server and the flag
3555 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3557 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3559 * Renamed NAMES command to USERS command. The NAMES was named that
3560 due to historical reasons. Now it is renamed. Also, rewrote
3561 parts of the USERS command. The nickname list is not sent anymore
3562 by the server. Only Client ID and mode lists are sent in the USERS
3563 command. Changed this also to the protocol specification.
3565 The client now resolves the names and stuff after it receives
3566 the USERS list from the server when joining to the channel.
3568 * WHOIS and IDENTIFY commands has been changed to support multiple
3569 Client ID's per command. One can now search for multiple users
3570 in the network by sending only one WHOIS or IDENTIFY command.
3571 Changed the code and the protocol specifications.
3573 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3574 uses silc_server_command_whois_parse to parse the request. */
3576 * If normal server, do not parse the WHOIS and IDENTIFY requests
3577 before sending it to the router. Saves some time.
3579 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Fixed JOIN command on client library. Wrong number of arguments
3582 used to crash the client.
3584 * Added silc_server_channel_has_global function to check whether
3585 channel has global users or not.
3587 * Added silc_server_channel_has_local function to check whether channel
3588 has locally connected clients on the channel.
3590 * The silc_server_remove_from_one_channel now checks whether the
3591 channel has global users or not after given client was removed from
3592 the channel. It also checks whether the channel has local clients
3593 on the channel anymore. If it does not have then the channel entry
3594 is removed as it is not needed anymore.
3596 * The silc_server_notify now checks on JOIN notify whether the joining
3597 client is one of locally connected or global. If it is global then
3598 the channel has now global users on the channel and that is marked
3599 to the channel entry. Also, it now saves the global client to
3600 global list who is joining and JOINs it to the channel. This is
3601 for normal server, that is.
3603 Changed silc_server_send_notify_on_channel,
3604 silc_server_packet_relay_to_channel and
3605 silc_server_packet_send_to_channel check if we are normal server
3606 and client has router set (ie. global client) do not send the
3607 message to that client, as it is already routed to our router.
3609 * Implemented LEAVE notify type handling in silc_server_notify
3612 * Tested LEAVE command in router environment successfully. Tested
3613 with two routers, two servers and two clients.
3617 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3619 * Implemented SIGNOFF notify type handling in silc_server_notify
3622 * silc_server_remove_id now removes the client entry from all channels
3623 it has joined and thusly sends SIGNOFF notify type.
3625 * Rewrote the NAMES list generation in server by removing two excess
3626 loops. The lists are created now inside one loop.
3628 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * silc_server_remove_channel_user checks now also global list
3631 for channel and client.
3633 * silc_server_new_channel_user checks now both local and global
3634 list for channel and client. Fixed a bug in client id decoding.
3635 Used to decode wrong buffer.
3637 * silc_server_channel_message checks now both local and global
3638 list for channel entry.
3640 * Tested channel joining (hence JOIN) in router environment
3641 successfully. Tested with two routers, two servers and two
3644 * Tested channel message sending in router environment successfully.
3646 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added silc_server_save_channel_key into server.[ch] to save the
3649 received channel key in Channel Key payload processing. It is
3650 also used in JOIN command reply handling.
3652 Equivalent function silc_client_save_channel_key added into
3653 client.[ch] into client library.
3655 * Changed JOIN command reply to send information whether the channel
3656 was created or not (is existing already) and the channel key
3657 payload. Changed protocol specs accordingly.
3659 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3660 the request was sent by ID and not by nickname. Crashed on
3663 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3666 now correctly save the received data.
3668 * silc_server_free_sock_user_data now notifies routers in the
3669 network about entities leaving the network.
3671 At the same time implemented functions silc_server_remove_id
3672 and silc_server_send_remove_id to receive and send REMOVE_ID
3673 packets. The packet is used to notify routers in the network
3674 about leaving entities. The ID removed will become invalid in
3677 * Added function silc_idlist_del_server into server. Removes and
3678 free's server entry from ID list.
3680 * silc_server_private_message function now checks, if we are router,
3681 that the destination ID really is valid ID, naturally.
3683 * In router when NEW_ID packet is received (for new client) the
3684 hash of the Client ID is saved in the ID Cache but the
3685 client->nickname is set to NULL, instead of putting the hash
3688 IDENTIFY command now also checks that client->nickname must be
3689 valid. If it is not if will request the data from the server who
3690 owns the client. Added new function
3691 silc_server_command_identify_check.
3693 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3694 to set the command to already allocated Command Payload.
3696 * Tested private message sending in router environment with two
3697 routers, two servers and two clients. Fixed minor bugs and now
3700 * Fixed segfault from client's NAMES command. Used to crash if
3703 * Forwarded packets must not be routed even if it is not destined
3704 to the receiver. Changed server code comply with this.
3706 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added `require_reverse_mapping' boolean value to ServerParams
3709 structure. If TRUE (not default) the server will require that
3710 the connecting host has fully qualified domain name.
3712 If the reverse mapping is not required and hostname could not be
3713 found the IP address is used as hostname.
3715 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Implemented version string checking to both client and server.
3718 The check is incomplete currently due to the abnormal version
3719 strings used in development version of SILC.
3721 * Changed all command functions in server to use the new
3724 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Changed char *data to unsigned char *data in ID Cache system to
3727 support binary data as ID Cache data. Changed code to support
3728 binary data in lib/silccore/idcache.c.
3730 * Renamed silc_server_packet_relay_command_reply to
3731 silc_server_command_reply as it is normal packet receiving
3732 function. Rewrote the function to accept command replys for
3733 servers and not only for clients.
3735 * Mark remote router always as registered server if we are connecting
3736 to it. Otherwise, commands sent by the router to us are ignored.
3738 * All ID List find routines now returns the ID Cache Entry pointer
3739 as well if requested.
3741 * WHOIS command works now in router environment, tested with two
3742 routers, two servers and two clients.
3744 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3745 in router environment (as it is almost equivalent to WHOIS) but
3746 hasn't been tested thoroughly. Added new functions:
3748 silc_server_command_identify_parse
3749 silc_server_command_identify_send_reply
3750 silc_server_command_identify_from_client
3751 silc_server_command_identify_from_server
3753 * Disabled route cache adding because adding two different ID's with
3754 same IP replaces the old cache entry thus giving wrong route.
3755 The entry->router->connection is always the fastest route anyway
3756 so route cache may not be needed. Of course, new routes maybe
3757 established after receiving the ID when the entry->router->connection
3758 might not be anymore the most optimal.
3760 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Add route cache for received ID for fast routing.
3764 * Added silc_server_packet_route to route received packet on router
3765 that is not destined to us.
3767 * Renamed silc_server_get_route to silc_server_route_get.
3769 * Added id_string and id_string_len fields into SilcServer to
3770 include encoded ServerID for fast comparing without excess
3771 encoding of the ID's.
3773 * Cleaned up WHOIS command on server side. Added following static
3776 silc_server_command_whois_parse
3777 silc_server_command_whois_check
3778 silc_server_command_whois_send_reply
3779 silc_server_command_whois_from_client
3780 silc_server_command_whois_from_server
3782 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3783 arguments in command replies. All command functions should be
3784 updated to use this macro.
3786 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Minor typo fixes on command reply handling on server.
3790 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Added silc_server_command_add_to_channel internal routine to add
3793 the client to the channel after router has created the channel and
3794 sent command reply to the server.
3796 * Added generic silc_server_send_command to send any command from
3799 * Use static buffer with ID rendering instead of duplicating data.
3801 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Fixed a channel user mode bug when joining to a channel server gave
3804 everybody channel founder rights, oops.
3806 * We mark ourselves as the router of the incoming server connection
3807 if we are router ourselves. This way we can check in some packet
3808 sending functions whether it is locally connected server. For
3809 incoming router connections we put NULL.
3811 * For router sending packets locally means now always sending the
3812 packet cell wide; to local clients and local servers. For normal
3813 server sending packet locally means sending it to only local
3816 * Fixed the JOIN command to really work in router environment. If the
3817 channel is created it is always created by the router. Router is
3818 also responsible of making the initial joining to the channel,
3819 sending JOIN notify to the sending server and distributing
3820 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3821 does not exist server doesn't do anything else but forward the
3822 command to the router which performs everything.
3824 * Added silc_server_send_channel_key function to send the Channel Key
3827 * Added silc_server_create_channel_key to create new channel key. The
3828 channel key is now re-generated everytime someone joins or leaves
3829 a channel, as protocol dictates. Note: channel->key_len is the
3832 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3835 packet_receive.[ch] to separate packet sending and receiving
3836 routines. The server.[ch] now includes everything else including
3837 actual packet processing (writing and reading data) and other
3840 Renamed silc_server_private_message_send_internal to
3841 silc_server_send_private_message. The routine is still though
3842 used only to relay private messages as server does not send
3843 private messages itself.
3845 Renamed silc_server_new_channel to silc_server_create_new_channel
3846 and added new function sicl_server_new_channel that handles the
3847 incoming New Channel packet. Added also new sending function
3848 silc_server_send_new_channel to send New Channel Payload.
3850 * Added new function silc_server_notify to process incoming notify
3851 packet to the server/router. Server may then relay the notify
3852 to clients if needed.
3854 * Added new function silc_server_new_channel_user to process incoming
3855 New Channel User packet. Router will redistribute the packet and
3856 send JOIN notify to its local clients and locally connected servers
3857 if needed. Normal server will send JOIN notify to its local client
3858 on same channel when received this packet. Added also corresponding
3859 sending function silc_server_send_new_channel_user to sent the
3862 * Added boolean route argument to send_notif_to_channel and
3863 packet_send_to_channel functions to attempt to route the packet
3864 if it is TRUE and send only locally if it is FALSE.
3866 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * silc_server_replace_id now broadcasts the received replace ID
3869 packet if it is not broadcast packet already. The router must
3870 broadcast to inform other routers about changed ID.
3872 * Added backpointer to server's router into SilcServer context in
3873 silcd/server_internal.h.
3875 * Fixed silc_server_packet_broadcast to send correct broadcast
3878 * The channel key is now distributed to the local client as soon
3879 as it is received from the router (in router environment) so that
3880 no other packet may be sent for the channel until client has
3883 * silc_server_remove_channel_user now broadcasts the received
3884 Remove Channel User packet if it is not broadcast packet already.
3885 The router must broadcast to inform other routers about removed
3888 * Added users field into SilcPacketContext that is a reference count
3889 of the context. One can increase the reference count by calling
3890 silc_packet_context_dup which is now changed to just increase the
3891 reference count instead of duplicating the data. The reference
3892 count is decresed by calling silc_packet_context_free that will
3893 free the data after the reference count hits zero.
3895 For now on the packet context and everything allocated into it
3896 (including the raw packet from network) must be freed by calling
3897 the new silc_packet_context_free function. Added also new function
3898 silc_packet_context_alloc that must be used now to allocate the
3899 context. This also means that if a routine is asynchronous from
3900 silc_[client/server]_packet_parse_type the packet context must
3901 be duplicated by calling silc_packet_context_dup. Otherwise it
3902 gets free'd after silc_[client/server]_packet_parse_type returns.
3903 Also, one must remember that if packet is duplicated then its
3904 reference count must be decresed by calling the free function as
3905 many times as it was duplicated.
3907 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3908 from both client and server.
3910 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Made joining to a channel working in router environment.
3914 * Cleaned up JOIN command on server side and create function
3915 silc_server_command_join_channel internal routine to make the
3918 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Changed silc_command_pending list to SilcDList. Also, added
3921 `ident' field to SilcServerCommandPending structure to identify
3922 the reply and to call correct callback.
3924 Added silc_server_command_pending_check function to replace the
3925 corresnponding macro. The silc_command_pending list is not
3928 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3929 to set identifier to previously allocated Command Payload. It
3930 is used to set identifier for command when resending Command
3933 * Added silc_command_payload_encode_payload to encode Command
3934 Payload buffer from SilcCommandPayload structure.
3936 * Added silc_argument_payload_encode_payload to encode Argument
3937 payload buffer from SilcArgumentPayload structure.
3939 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Changed WHOIS command to support router connection on server side.
3942 The whois request is always sent to router unless the server is
3943 standalone server. After server has received the reply from the
3944 router will it send the reply to the client.
3946 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3947 broadcast received broadcast packet. The function is used only
3948 by router. The broadcast packet is always sent to the router's
3951 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3952 render given ID to printable string, for log files for example.
3954 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Made basic router to router connections working. At least they
3957 can now connect to each other but nothing really works the way
3958 they are supposed - yet.
3960 * Added new initiator token to RouterConnection configuration
3961 file in silcd/serverconfig.[ch]. It is used to tell whether we
3962 are the initiator to the remote router or whether we'll expect
3963 the other end to connect.
3965 * Moved registering of listener task to silc_server_init, hence
3966 the server starts listenning as soon as it is run, even if it
3967 does not have connections to other routers. Let's see how well
3970 * Changed default connection retry timeouts for more suitable in
3973 * Removed cipher and such arguments from silc_idlist_add_client
3974 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3975 Added new function silc_idlist_add_data to add the keys and stuff
3978 * Added SilcIDListData structure and added it to SilcClientEntry
3979 and SilcServerEntry as their first field in the structure. This
3980 way we can explicitly cast the ID entries to the SilcIDListData
3981 structure and get common data for the entries. In past, we had
3982 to first check what type of connection it is and then cast it to
3983 correct ID entry type. Now, we can directly cast the opaque
3984 pointer to the SilcIDListData (no matter what ID entry it actually
3985 is) and get the data needed.
3987 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3989 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3990 in some circumstances even if threre were timeout tasks, though not
3991 IO tasks, but tasks anyway. Now fixed.
3993 * Defined SilcServerConnection structure to hold connection specific
3994 stuff about directly connected servers and routers. The definition
3995 is currently in silcd/server_internal.h. I thought about having
3996 a bit more important role fro this struct but for now it is used
3997 only when connecting to other server (or router actually).
3999 * Added connecting retry support in server when connecting to
4000 router(s). The retry feature implement exponential backoff
4001 algorithm. Also, added SilcServerParams structure to hold default
4002 parameters for server. For now, it include these retry settings
4003 and are hard coded. After server is moded to be as Silc Server
4004 Library this structure will be more important.
4006 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Changed client librarys channel->clients table to SilcList and
4009 changed code accordingly.
4011 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Changed client's channel table to SilcList and changed code
4014 accordingly. Also changed SilcChannelClientEntry to include back-
4015 pointer to the channel so that client entry can use that structure
4016 as list as well and we have fast cross-reference to the channel.
4017 This change dramatically decreased the complexity of channel
4018 handling with client entry and vice versa (removed one extra
4019 loop when searching for channel entry from many functions).
4021 * Changed server->sim from table to SilcDList and changed code
4024 * NAMES command can now be used from user interface. It will show
4025 the user list on the channel, neatly.
4027 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4028 Code now saves realname of the user if it becomes available.
4030 * Renamed configure.in to configure.in.pre and made ./prepare
4031 script to automatically add correct version string to
4032 configure.in which it creates from configure.in.pre.
4034 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * NAMES command reply now shows users mode with the nickname when
4039 * Moved silc_client_ch[u]mode[_char] functions from
4040 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4041 place sucks, they are utility functions and should be in some
4044 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4046 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4049 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * Added TRQ (efficient deque and list library) into lib/trq. This is
4054 a very good list library that is currently used in the SILC. Defined
4055 SilcList API over the library because I didn't like the API very
4056 much. See lib/trq/silclist.h for the API and examples of how to
4057 use the API. Fixed various places in the code to use the new
4058 SilcList API. The SilcList is meant for lists that has a structure
4059 already defined as a list. It is not suitable to add just some
4060 context to the list (in TRQ, the context is the list actually).
4062 So, I defined SilcDList that can be used for the purpose where
4063 predefined list structure does not exit. This can be used as
4064 such list. Now some context just can be added to the SilcDList.
4065 Currently this list is not used in the SILC just yet, though there
4066 are a lot places where this can replace dynamically allocated
4067 tables and I will fix these places, later, to use SilcDList.
4068 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4069 and use TRQ internally).
4071 Also fixed some annoying warning messages that the original TRQ
4072 code generated. Also minor changes to TRQ's Makefile.in.
4074 * Added support for querying by Client ID to both WHOIS and
4075 IDENTIFY commands into server, as required by the protocol.
4077 * Removed method function pointers from SilcBuffer structure. They
4078 weren't used to anything and just increased the context size for
4079 no good reason. This change also made silc_buffer_alloc and
4080 silc_buffer_free functions inline functions.
4082 * Disabled command flooding detection support until it's fixed so
4083 that it accepts commands in but does not execute them more than once
4086 * Added silc_net_localhost(), to return local hostname, into
4087 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4088 that must be initialized before calling silc_client_init.
4090 * Added new function: silc_server_send_notify_on_channels to send
4091 notify messages to all channels client has joined. It is assured
4092 that the message is sent only once per client.
4094 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4095 lib/silcutil/silcutil.[ch] as silc_format function. The new
4096 function is generic and is used by server as well, not only by
4097 the logging routines.
4099 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4100 the provided version string was not acceptable. Added new function:
4101 silc_ske_check_version into lib/silcske/silcske.h. The function
4102 must be implemented by the application (client or server) and it
4103 does not reside in the SKE library. The function checks the version
4104 string remote end sent.
4106 * Added back pointers (to opaque context and to SilcSocketConnection)
4107 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4109 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4110 duplicate packet context structure.
4112 * Changed `notify' client operation to send same arguments as client
4113 receives from server except for ID's. ID's are mapped to correct
4114 ID entry and that is returned. Also, if channel entry is not sent
4115 by server but the notify is for channel the channel entry is sent
4116 to application (otherwise application doesn't know that it is for
4117 channel (library gets it from packet's Destination ID)).
4119 * Added silc_client_remove_from_channels into client library to
4120 remove a client from all channels it has joined to. Used when
4121 received SIGNOFF notify from server. Added also new function
4122 silc_client_replace_from_channels to replace old ID entry with
4123 new ID entry on all channels. Used when received NICK_CHANGE
4126 * Fixed ID Cache list handling in silc_idlist_get_client in
4127 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4128 to get (or query) client by ID.
4130 * Updated TODO list.
4132 * Added connection authentication status message defined by the
4133 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4134 support for these into the code in client and server side.
4136 * Added generic function silc_client_send_command to send any command
4137 with variable argument list. Application should use this function
4138 to send commands if the command functions provided by the library
4139 does not suite for the application's user interface needs.
4141 * Added new `failure' client operation. Application is notified about
4142 received failure packet if client is executing a protocol. In this
4143 case the protocol's execution has failed.
4145 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4146 is required by the protocol.
4148 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4149 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4152 * Added status flag to SilcSKE object to indicate realtime status
4153 of the SKE protocol.
4155 * Application receives now exactly same command reply arguments as
4156 the library receives from server. However, if ID is received the
4157 corresponding ID entry is returned to the application (eg. Client
4158 ID is mapped to correct SilcClientEntry entry and that is returned).
4159 Changed command_reply client operation due to this change.
4161 * Changed all ID's in commands and in command replys as ID Payloads.
4162 Change affected both client and server side codes.
4164 All ID's sent in SILC network (with execption of ID's in SILC
4165 Packet header) are sent in ID Payload to support variable length
4168 * Server now notifies nick changes and notifies all clients on
4169 the channels about the new nickname (about the new Client ID,
4172 * Implemented CMODE command to change channel modes. Supports all
4173 channel modes defined by the protocol specs except ban and invite
4174 lists. (Also, private channel key mode is supported but support for
4175 setting private channel key in client is missing, thus, this mode
4176 has no effect on client side (except that server requires that the
4177 client uses private channel key and normal channel traffic does not
4180 Also, invite mode works per se, but INVITE command does not work
4181 yet correctly, so you can set channel as invite only channel but
4182 inviting clients to the channel does not work (it is yet to be
4183 thought what's the best way to do it).
4185 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4186 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4187 Implemented CUMODE command to change user's mode on the channel.
4188 Supports all modes defined by the protocol specs.
4190 * Added NAMES command reply to return users modes on the channel.
4192 * Removed unnecessary and slow ciphers from lib/silccrypt.
4194 * Set SO_KEEPALIVE option to connection sockets by default.
4196 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4198 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4199 redefined the Notify Payload into protocol specs.
4201 * Added silc_id_payload_parse_id to get ID directly from raw
4204 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4207 accept searching by Client ID as well.
4209 * Added support for LEAVE and SIGNOFF notify types in client library.
4211 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4212 to parse ID Payload from raw data.
4214 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Added flags parameter into silc_ske_assemble_security_properties
4217 function in lib/silcske/silcske.[ch].
4219 * Changed notify client operation to fit better for notify messages
4220 sent by server. The notify payload received from server is now
4221 passed to the application (after parsing it to SilcNotifyPayload).
4222 It is application's responsibility to retrieve the arguments
4223 from the payload and show the message the way it wants. The message
4224 sent by server is implementation specific.
4226 * Changed public keys to comply with the protocol specification.
4227 Old public keys are not supported anymore and are not compatible.
4229 * Removed nickname from Channel Payload as the latest draft removed
4230 it. The client must resolve the nickname from the NAMES command
4231 reply received when it joined the channel.
4233 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4235 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Fixed some errors in protocol specification drafts.
4239 * Created lib/silccore/silcnotify.c to implement Notify Payload
4240 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4241 generic payloads described by protocol specifications. The file
4242 includes implementations for ID Payload and Argument Payload.
4244 * Changed Command Payload implementation to use the new Argument
4245 Payload. Changed command_xxxx_payload to command_payload_xxxx
4246 to comply with SILC coding conventions.
4248 * Added suppport for Argument Payload handling in Notify Payload
4249 implementation as protocol requires it. Added the new support
4250 into server and client lib as well.
4252 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Added support for multiple nicknames on same channel. [n] is
4255 added locally to the nickname if there are more than one same
4256 nicknames on the channel.
4258 * Server now sends all nicknames that matched WHOIS request.
4259 Client also shows the list received from server.
4261 * Added TOPIC command to client side. User can now set and show
4262 current topic on channel.
4264 * Added MOTD command to client and server. Also, server sends the
4265 motd when client connects to the server.
4267 * Changed version strings to comply ISO 8601.
4269 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Fixed protocol error handling in client library. It should now
4272 cope even if the SKE fails for some reason.
4274 * Made new protocol specification drafts for submitting to IETF.
4276 * Implemented TOPIC command to server in silcd/command.c.
4278 * Added two new notify types into lib/silccore/silcnotify.h:
4279 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4280 notify nickname change and topic setting/change on a channel.
4282 * API change of command_reply operation in client library. The
4283 application gets now the status type received from server as well.
4285 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4289 * Cras fixed and optimized the packet handling even further and
4290 it should work now. Minor change to the prototype of function
4291 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4293 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Added new function into lib/silcutil/silcschedule.[ch]:
4296 silc_schedule_with_fd to select() a specified fd. The function
4297 returns after timeout expires or data arrives or goes. The
4298 function is used by packet routines to wait that all data is
4299 received from network.
4301 * Fixed data reading from network in lib/silccore/silcpacket.c.
4302 The code now assures that all data is read from the fd and then
4303 continues packet processing. This was a bug fix since the code
4304 used to drop some data in some circumstances.
4306 * Added new function into lib/silcclient/client.[ch]:
4307 silc_client_start_key_exchange to start key exchange after
4308 connection has been established to server. The code internally
4309 now uses this funtion but its main purpose was to provide it
4310 for applications that perform their own connecting. After
4311 application has created a connection it merely calls this
4312 function to start the key exchange between client and server.
4313 The library takes care of everything else after that.
4315 Updated also lib/silcclient/README to explain the usage of
4318 * Do not send to application information that connection has
4319 been established. Application gets notified it by connect
4322 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Applied cras's patch to add silc_schedule_one function. The
4325 function runs scheduler once and returns.
4327 * Fixed the scheduler after cras messed it up. The timeout
4328 handling works now as it's supposed to work.
4330 * Added into lib/silccore/ silcnotify.h to include notify
4331 message types support. Changed silc_server_send_notify*
4332 functions, in server.[ch], to support those new notify types.
4333 Added the support for the notify types into client library,
4334 as well. Added new notify client operation into ops.h in
4337 * Changed silc_server_packet_send_to_channel to send normal
4338 packets instead of just channel message packets. The function
4339 is now used to send the notify packets to channels. It is not
4340 used to send channel message packets anymore, as server never
4343 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4344 va_arg()s as it seems to require it nowadays. I guess, if SILC
4345 is compiled with older va_arg() the new code should work anyway.
4347 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Splitted core library. Core library (lib/silccore) includes
4350 now only SILC protocol specific core (and common) components.
4351 Created new utility library (lib/silcutil) that includes more
4352 generic purpose stuff. The stuff for util library was taken
4353 from the old core library. This was minor and easy split.
4355 * Created SILC Client Library (lib/silcclient) that includes
4356 implementation of the SILC client without user interface. This
4357 was major move from silc/ directory. The code has been changed
4358 so that it is transparent towards the user interface. The
4359 silc/ directory includes now the same user interface as before
4360 and it uses the new client library. Read lib/silcclient/README.
4361 Basicly, the client library performs everything else related
4362 to SILC except user interface handling. Also, configuration
4363 files are considered to be part of user interface and library
4364 does not handle them.
4366 This change also changed a lot of structures, function naming etc.
4367 Most important change was that SilcClientWindow object was
4368 renamed to SilcClientConnection in the client library. Created
4369 also new file lib/silcclient/ops.h. Also added new files
4370 silc/local_command.[ch] and silc/client_ops.[ch].
4372 All these changes were made to make it easier for user interface
4373 designers to create what ever user interface for the SILC client
4376 It is also expected that the server will be moved to lib
4377 directory as well and SILC Server Library will be created;
4378 sometimes in the future.
4380 * Removed Local commands from lib/silccore/silccommand.h as
4381 they are application specific and new client library does not
4382 handle any of those anymore.
4384 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4385 old client implementation in silc/.
4387 * Added support for callback functions in SILC_LOG_* macros.
4388 Application can now set its own callbacks that will be called
4389 instead of using the default functions that will always print
4390 the debug messages to stderr (or stdout). Also, debugging can
4391 now be disabled by setting silc_debug to FALSE and re-enabled by
4392 setting it to TRUE. Note, that logging will still work even
4393 if debugging is disabled.
4395 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4396 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4397 silc_log_reset_debug_callbacks.
4399 * To enable debugging in silc client one must give now -d
4400 option on command line.
4402 * Changed silc_schedule_init to automatically allocate task queues
4403 if they are not allocated before calling it.
4405 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Added GMP 3.1 into math library.
4409 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4412 a channel in SILC network. The packet is used by servers and
4413 routers to notify other routers that user has left a channel.
4414 This little feature was missing until now. Added the feature
4415 to protocol specification as well.
4417 Added functions: silc_server_send_remove_channel_user and
4418 silc_server_remove_channel_user into server.[ch].
4420 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4421 lib/silccore/silcpacket.h. However, they are not implemented
4424 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Fixed joining to a channel and sending channel messages
4427 between server and router. The channel message sending should
4428 now work inside a cell.
4430 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Fixed the private message sending between server and router.
4433 The private message sending should now work inside a cell.
4435 * Added silc_server_replace_id into server.[ch] to replace
4436 existing ID in the SILC network.
4438 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4439 and silc_idlist_replace_server_id into idlist.[ch] in server.
4441 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Fixed the server to server connections. Server can again now
4444 connect to router. Router to router connections probably does
4447 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added dynamic protocol registering support. Now protocols can
4450 registered and unregistered on the fly. Patch by cras.
4452 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Added lib/contrib directory to hold routines that some platforms
4455 don't have but are needed by SILC.
4457 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4458 into lin/contrib to provide getopt() and getopt_long() for
4459 those who don't have it.
4461 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added AWAY command to client. When away message is set and
4464 client receives a private message packet the client automatically
4465 replies to the sender with the away message.
4467 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4468 bug seemed to be the cause of recent problems when compiling
4471 * Added version detection support to SKE protocol specification
4472 and added the new changes to the SKE implementation as well.
4473 There were other minor changes in the SKE protocol as well.
4475 Many changes in lib/silcske/silcske.[ch] and in
4476 lib/silcske/payload.[ch].
4478 * Added ^U functionality, clear input line. Patch from cras.
4480 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Mainly small bugfixes on core library. Fixed some debugging
4483 logging and buffer overflow in silclog.c.
4485 * Updated config.sub and config.guess on the distribution tree.
4487 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Added command lagging support in server. Client may execute
4490 commands now only once in two seconds.
4492 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Optimized packet reception. MAC computation and checking is now
4495 also more optimized. A lot previously duplicated code is now
4496 used as generic by both client and server.
4498 * Fixed key pair generation in clientutil.c
4500 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Added into lib/silccore/silcbufutil.[ch] new function;
4503 silc_buffer_realloc.
4505 * Moved generic packet sending/encryption functions to
4506 lib/silccore/silcpacket.[ch] from client and server. Some
4507 rewriting of the functions.
4509 * Moved all generic packet reception/decryption functions to
4510 lib/silccore/silcpacket.[ch] from client and server. The
4511 packet processing is now much cleaner in both client and server.
4512 These were major changes in both client and server.
4514 * Created many common functions in server to do packet sending.
4515 Previously code were duplicated a lot, this has been removed
4518 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Rewrote major parts of the ID cache system. Don't know
4521 whether it is better now or not but at least the API is more
4524 * Major rewrite on ID cache stuff on client because of the ID
4525 cache API changes. Added idlist.c to client.
4527 * Also major rewrite on ID cache stuff on server as well.
4528 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4529 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4530 in hand, instead they are all put into the ID cache system now.
4531 All server_idlist_* routines uses ID cache now instead of
4532 traversing its own lists (those lists does not exist anymore).
4533 SilcIDList though still exists. Also, SilcXXXEntry's are
4536 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Finally made the SKE implementation compliant to the protocol
4539 specification. All mp integers are now binary encoded as
4540 opposed being HEX encoded.
4542 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4545 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4546 functions: silc_[encode/decode]_pem. Also added function
4547 silc_encode_pem_file to PEM encode with newlines ('\n') for
4550 * SILC public keys are now encoded either PEM or binary. Same
4551 option is for private keys as well. By default private keys
4552 are binary encoded and public keys PEM encoded. Silly HEX
4553 encoding were removed.
4555 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4556 function to create fingerprints.
4558 * Fixed a bug in SHA1; does not change the original data anymore.
4560 * Partly implemented INFO command on client and server side.
4561 Fixed CLEAR command. Changes to SERVER command; show current
4562 server(s) when giving command without arguments. Added
4563 VERSION command to client.
4565 * Added check to server that unregistered connections cannot
4566 execute commands (unless it is specificly allowed).
4568 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Fixed screen refresh.
4572 * Fixed channel joining bug from client. On some circumstances
4573 client tried to join to a channel it had already joined.
4575 * Added public key verification process into client's protocol.c.
4576 The client now verifies the public key from user and saves
4577 it into ~./silc/serverkeys/ directory.
4579 Added into: clientutil.[ch]: silc_client_verify_server_key.
4581 * Changed SKE protocol's silc_ske_initiator_finish function
4582 to accept callback function that verifies the received public
4583 key. Removed old silc_ske_verify_public_key function.
4585 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4588 silc_pkcs_private_key[_data]_set.
4590 * Made the password and public authentication more cleaner in
4591 server's protocol.c.
4593 * Removed historic and obsolete protocol `channel_auth' from
4594 both client and server.
4596 * Removed wrong way of sending command status messages from
4597 server to client in server's command.c. The old way violated
4598 protocol specification.
4600 Changes to silccore/silccommand.[ch]: removed
4601 silc_command_encode_status_payload -> not needed anymore,
4602 changed silc_command_encode_payload_va to accept extra
4603 argument on variable argument list. The argument type must
4604 now be provided to the function. Also, added new function:
4605 silc_command_encode_reply_payload_va which is same as
4606 normal command_encode_payload_va except command status type
4607 is provided as extra argument.
4609 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Added ~./silc directory handling. The directory includes the
4612 public and private keys for the client.
4614 Added silc_client_check_silc_dir, silc_client_create_identifier
4615 and silc_client_load_keys.
4617 * Implemented SILC protocol compliant public key. Added public
4618 and private key saving to and loading from files.
4620 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4621 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4622 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4623 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4624 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4626 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4627 silc_pkcs_load_[public/private]_key.
4629 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added silc_server_get_route (route.[ch]) to get connection
4632 data for the fastest route for given ID.
4634 * Implemented INVITE command on client and server. The command
4635 were re-defined in the SILC Protocol Specification and the
4636 implementation now complies with the specification.
4638 * Implemented PING command on client and server.
4640 * Implemented NAMES command on client and server. The server side
4641 supports currently only normal server not router server yet.
4642 Some changes to NAMES definition in SILC protocol specification.
4644 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Implemented LEAVE command on client and server.
4648 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4649 again. This change was made to the protocol as well. Server
4650 should not violate the protocol specification anymore.
4652 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4655 was tested. SOCKS4 was not but should work anyway.
