1 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4 which is given as argument to the silc_client_alloc now.
5 It can be used to configure the client and set various parameters
6 that affect the function of the client.
8 * The USERS command in server did not check whether the channel
9 is private or secret. Affected file silcd/command.c.
11 * Added new argument to the USERS command in protocol specification.
12 The USERS command now can take the channel name as argument
13 as well. Added support for this in client and server and
14 updated the protocol specs.
16 * Completed the GETKEY command in client. It can be now used
17 to fetch also servers public key not only some clients.
18 Affected files lib/silcclient/command[_reply].c.
20 * Added silc_client_get_server to return server entry by the
21 server name. Affected files lib/silcclient/silcapi.h and
24 * Redefined the IDENTIFY command in protocol specification to be
25 more generic. It now can be used to query information about
26 any entity in the SILC Network, including clients, servers and
27 channels. The query may be based either the entity's name
28 or the ID. Added support for this in both client and server.
30 Affected files silcd/command.c and lib/silcclient/command.c
33 * Optimized the WHOIS and WHOWAS commands in the server. Removed
34 the _from_client and _from_server functions. Affected file
37 * Added silc_client_get_channel_by_id_resolve to the file
38 lib/silcclient/silcapi.h to resolve channel information by
39 its ID. Added also silc_client_get_channel_by_id that
40 does not resolve it from the server.
42 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
44 * Added SilcServerEntry context into the client library
45 to represent one server. The INFO command now allocates
46 these to save the resolved server info. For now on the
47 client library will also keep information about servers,
48 connected and resolved with INFO.
50 The INFO command now allocates the SilcServerEntry context
51 and saves the server info there. The COMMAND_REPLY in
52 the INFO now returns the parameters to application in
53 same order as defined in the protocol specification.
55 The entries are cached in the client->server_cache.
57 * The INFO command is now issued after received the Client ID
58 from the server. Affected file lib/silcclient/client.c.
60 * The CMODE_CHANGE notify may now return also an SilcServerEntry
61 to the application as the mode changer might be server.
62 It is guaranteed that NULL is not returned anymore to the
63 application. Affected file lib/silcclient/client_notify.c.
65 The ID Type is now also passed to the application so that
66 it can check whether the returned entry is SilcClientEntry
69 Added new function silc_client_get_server_by_id to return
70 the server entry by ID. Affected files are the
71 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
73 * Do not create the channel in the Irssi SILC Client when issuing
74 the JOIN command but when received the sucessful JOIN command
75 reply. Otherwise the channel might get created even though we
76 could not join it. The Affected file is
77 irssi/src/silc/core/[silc-channels.c/client_ops.c].
79 * Fixed a channel joining bug in router. The router must also
80 check the channel modes, invite and ban lists etc. when serving
81 the JOIN command sent by normal server. Affected file is
82 silcd/command.c. The router now resolves the client's
83 information from the server who sent the JOIN command if it
84 does not know it, and processes the JOIN command only after
87 * Changed the SilcCommandCb to take new argument; void *context2.
88 Affected file lib/silccore/silccommand.h
90 The second argument in the command callbacks in the server now
91 includes the SilcServerCommandReplyContext if the command was
92 called as pending command callback from the command reply.
93 Otherwise it is NULL. When called as pending the status of the
94 command reply will be checked and if it was erronous the
95 error will be sent to the original sender of the command.
96 This way the client always receives the error messages even
97 though the server was actually the one who received the error
98 when it resent the command to router, for example. Affected
99 files silcd/command[_reply].[ch].
101 * Fixed sending WHOWAS command's error message to client if
102 the requested client could not be found. It was missing.
105 * Changed the CMODE and CUMODE commands reply arguments in the
106 protocol specification. The Channel ID is now sent in both
107 of the commands to identify the channel. Implemented this
108 new feature to the client and server. Affected files
109 lib/silcclient/command_reply.c and silcd/command.c.
111 * Made better checks for invite and ban lists in the JOIN
112 command in server. Affected file silcd/command.c.
114 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
116 * The server now performs the incoming host IP/DNS lookup
117 using the silc_socket_host_lookup and thus does not block
118 the server anymore. Affected file silcd/server.c.
120 * Completed the multi-thread support for SILC Scheduler in
121 the lib/silcutil/silcschedule.c.
123 * Fixed the configure.in.pre to detect the pthread correctly
126 * Fixed a deadlock in silc_task_queue_wakeup in the file
127 lib/silcutil/silctask.c.
129 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
131 * Added new function silc_schedule_wakeup that is used in
132 multi-threaded environment to wakeup the main thread's
133 schduler. It needs to be used when a thread adds a new task
134 or removes a task from task queues. After waking up, the
135 scheduler will detect the task queue changes. If threads
136 support is not compiled in this function has no effect.
137 Implemented the wakeup mechanism to both Unix and WIN32
138 systems. Affected files are lib/silcutil/silcschedule.[ch],
139 lib/silcutil/unix/silcunixschedule.c and the
140 lib/silcutil/win32/silcwin32schedule.c.
142 * Added new function silc_task_queue_wakeup to wakeup the
143 scheduler by the specified task queue. Affected file
144 lib/silcutil/silctask.[ch].
146 * The silc_socket_host_lookup_start now wakes up the scheduler
147 after adding the timeout task. Affected file is
148 lib/silcutil/silcsockconn.c.
150 * The silc_socket_host_lookup is synchronous now if the threads
151 support is not compiled in. However, the callback is still
152 called asyncronously through the scheduler, anyway. Affected
153 file lib/silcutil/silcsockconn.c.
155 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Added new function silc_socket_host_lookup to perform
158 asynchronous IP and FQDN lookups for the socket connection.
159 Affected files lib/silcutil/silcsockconn.[ch].
161 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
163 * Added SILC_MUTEX_DEFINE to define the mutex on environments
164 that may or may not compile the mutex support in.
166 Changed the silc_mutex_alloc interface. It allocates the
167 mutex now to the sent pointer and returns TRUE or FALSE.
169 Affected file lib/silcutil/silcmutex.h.
171 * Wrote the SILC Task Queue interface to support multi-threads.
172 Affected file lib/silcutil/silctask.[ch].
174 * Wrote the SILC Scheduler to support multi-threads. Affected
175 file lib/silcutil/silcschedule.c.
177 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Implemented the SILC Mutex API and SILC Thread API for WIN32
180 in lib/silcutil/win32/.
182 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Defined SILC Mutex API and SILC Thread API and implemented
185 them for Unix. Affected files are
186 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
187 lib/silcutil/unix/silcunixmutex.c and
188 lib/silcutil/unix/silcunixthread.c.
190 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
192 * Fixed the silc_server_remove_clients_by_server's channel
193 key re-generation. The hash table handling was incorrect
194 and would not work with many channels. Affected file is
197 * Fixed some memory leaks around the server code.
199 * Rewrote the silc_server_get_users_on_channel to support IPv6
200 based Client ID's. Affected file silcd/server.c.
202 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
203 specification. However, a separate document must be written
204 to define the detailed signing procedure and the payload
205 associated with the flag. Defined the flag to the
206 lib/silccore/silcchannel.h as well.
208 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
210 * Changed the dynamic tables to static size tables in the
211 lib/silccrypt/silchmac.c.
213 * Removed GCC dependencies from the code. A patch by cras.
215 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
217 * Do not show the error "Error receiving packet bla bla"
218 in server if it really was not an error (-2 means that reading
219 is pending). Affected file silcd/server.c.
221 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
223 * Fixed a possible crash in silc_server_remove_clients_by_server
224 in silcd/server.c. Fixed there also some memory leaks.
226 * Fixed the silc_idlist_replace_client_id. It could replace
227 wrong key in the hash table. Affected file silcd/idlist.c.
229 * Do not check whether there are global users on the channel
230 if the channel->global_users is FALSE. Affected functions
231 silc_server_remove_from_one_channel and
232 silc_server_remove_from_channels in silcd/server.c. Also,
233 do not check if the removed client is local as we can be
234 sure that global client was not removed from the channel
235 and checking for global users is not needed.
237 * The silc_server_remove_clients_by_server now re-generates
238 the channel keys correctly for those channels that had
239 clients removed from them. Affected file silcd/server.c.
241 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Found the reason of random crashes in the server. We weren't
244 ignoring the SIGPIPE signal (which can be sent in write())
245 and it crashed the server. Affected file silcd/silcd.c.
247 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
249 * Assure that sock->user_data is not NULL in the function
250 silc_server_packet_send in silcd/packet_send.c.
252 * Disconnect the remote connection if it could not be added
253 to any ID lists in the server. The affected file is
256 * Check in silc_server_packet_send[_real/dest] that the
257 socket is not disconnecting and ignore the data if it is.
258 Affected file silcd/packet_send.c.
260 * Define inline to __inline on native WIN32 compilation.
261 Affected file includes/silcwin32.h.
263 * Added some explicit type casts for inline code since MSVC
264 require them. Affected files lib/silcutil/silcbuffer.h,
265 lib/trq/silcdlist.h and lib/trq/silclist.h.
267 * Print warning in log files from now on if the packet
268 decryption fails. Affected file silcd/server.c.
270 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
272 * Changed the `say' client operation's interface to accept
273 new `type' argument to indicate the type of the message sent
274 by the library. The application may filter the library's
275 messages according the type. The affected file is the
276 lib/silcclient/silcapi.h.
278 * Added two new functions to lib/silcclient/silcapi.h:
279 silc_client_del_client and silc_client_del_client_by_id.
280 Affected file lib/silcclient/idlist.c.
282 * Moved the clientincludes.h from includes/ to silc/ and
283 serverincludes.h from includes/ to silcd/.
285 * The modes for the CMODE and CUMODE are now passed as
286 uint32 for application with COMMAND_REPLY. The affected
287 file is lib/silcclient/command_reply.c.
289 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
291 * /WHOIS without arguments shows client's own information.
292 Affected file lib/silcclient/command.c.
294 * Changed PING to not accept any arguments. The specs
295 says that client can ping only the connected server so
296 requiring an argument is not needed. Affected file is
297 lib/silcclient/command.c.
299 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
301 * Fixed a fatal bug in private message sending and reception
302 encryption and decryption when using private message keys.
303 The implementation was incorrect and did not follow the
304 specification. It causd that some of the message were
305 lost since it did not use the sending and receiving keys
306 as the protocol suggests. This has been fixed and will cause
307 incompatibilities with older clients when sending private
308 message encrypted with private message keys. Affected files
309 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
310 and various other in Irssi SILC Client.
312 Added `responder' boolean argument to the functions
313 silc_client_add_private_message_key[_ske] to indicate when
314 the key is added as responder or initiator of the key
317 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
319 * Removed the silc_ske_check_version function and created
320 a SilcSKECheckVersion callback. Added also a function
321 silc_ske_set_callbacks that is now used to set all SKE
322 callbacks. The callback functions are not given to
323 the SKE functions anymore, but this function is used to
326 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
328 * Added `silc_version' argument to the silc_client_alloc
329 to define the version of the application for the library.
330 The library will use the version string to compare it
331 against the remote host's (usually a server) version
332 string. Affected file lib/silcclient/silcapi.h
334 * Added the KE protocol context to Key Agreement context
335 in client library so that we can abort the SKE if it
336 is in process when we get timeout. Affected file is
337 lib/silcclient/client_keyagr.c.
339 * Do not resolve the client ID forever if it returns in the
340 first time that such client does not exist. This was done
341 for example with private message. Affected file is
342 lib/silcclient/client_prvmsg.c.
344 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Do not add regex.h for WIN32. The affected file
347 includes/silcincludes.h.
349 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
350 not work yet 100%. It generates the DLL's automatically
351 when compiling with --with-win32 under cygwin.
353 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
355 * lib/contrib/regex.c is not compiled on WIN32.
357 * Added silc_net_get_socket_opt function to the
358 lib/silcutil/silcnet.h.
360 * Added includes/silcwin32.h for WIN32 specific includes
363 * Do not use ptime structure or any of the posix process
364 functions on WIN32 in lib/silccrypt/silrng.c.
366 * Added silc_gettimeofday to provide generic function
367 for struct timeval on all platforms. Added the function
368 to lib/silcutil/silcutil.h.
370 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
372 * Moved the lib/silccore/silcsockconn.[ch] to the utility
373 library as they clearly belong there. As a plus side we
374 can make the actual socket connection routines platform
377 Added also new generic function silc_socket_read and
378 silc_socket_write (that used to be silc_packet_[read/write].
379 The implementation of these are platform specific.
381 * Added WIN32 specific routines of silc_socket_[read/write]
382 to lib/silcutil/win32/silcwin32sockconn.c.
384 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
386 * Added preliminary support for native WIN32 compilation under
387 cygwin (using the -mno-cygwin option for GCC) to the
388 ./configure.in.pre. The --with-win32 now prepares the
389 compilation for native WIN32.
391 * Rewrote the SILC Scheduler interface in the file
392 lib/silcutil/silcschedule.h. The scheduler is now context
393 based and does not have anymore any global static scheduler.
394 Moved the Unix scheduler to the lib/silcutil/unix/ directory
395 and created lib/silcutil/win32 directory for WIN32 based
398 * Added Unix specific network routines to the
399 lib/silcutil/unix/silcunixnet.c and the old
400 lib/silcutil/silcnet.c includes now only generic routines.
402 Added WIN32 specific network routines to the
403 lib/silcutil/win32/silcwin32net.c.
405 * Added Unix specific utility functions from the
406 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
408 * Added WIN32 SILC Scheduler to the file
409 lib/silcutil/win32/silcwin32schedule.c. The code is of course
412 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
414 * Do not handle JOIN notify in the server if the target client
415 is not registered (idata->registered == FALSE). The affected
416 file is silcd/packet_receive.c.
418 * Update the nickrec->founder in event_cumode in the Irssi SILC
419 client. Affected file irssi/src/silc/core/silc-channels.c.
421 * Fixed the CUMODE_CHANGE notify handling in the server when
422 server and router are announcing their clients on channels.
423 Now the mode changes are saved and notified correctly. The
424 affected file is /silcd/packet_receive.c.
426 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
427 They really did not replace the cache entry in the ID Cache.
428 Now they do that. Affected file silcd/idlist.c.
430 * Fixed the KICK notify handling in the Irssi SILC client to
431 update the channel records so that the kicked client does not
432 appear to be on the channel. The affected file is
433 irssi/src/silc/core/silc-channels.c.
435 * Always update the conn->current_channel when executing command
436 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
438 * Fixed the KILL notify handling in Irssi SILC client to remove
439 the killed client on all channels.
441 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Fixed the silc_parse_command_line to remove extra spaces
444 from the start and end of the arguments. Affected file is
445 lib/silcutil/silcutil.c.
447 * Cancel and free any active protocol in the function
448 silc_server_close_connection. Affected file silcd/server.c.
450 * Cancel and free any active protocol in the function
451 silc_client_close_connction. Affected file is
452 lib/silcclient/client.c.
454 * Do not execute the KILL command for clients that are in
455 history (ie. they are not in the network). Affected file is
458 * Fixed KILL notify handling, client does not crash anymore.
459 Affected file irssi/src/silc/core/silc-channels.c.
461 * Reduced the default packet buffer size from 2048 to 1024 in
462 lib/silccore/silcpacket.c.
464 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
465 counter to the SKE context that is incresed when the SKE library
466 performs async operation outside the library. If the outside
467 process frees the SKE context and FREED status will be set
468 and the library will detect after the sync operation that the
469 libary is freed. The affected files are
470 lib/silcske/silcske[_status].[ch].
472 * Resolve the client entry information in the function
473 silc_client_channel_message to assure that NULL pointer is not
474 passed as client entry to the application. */
476 * Fixed the task timeout calculation to assure that there is
477 never negative timeouts. The affected file is
478 lib/silcutil/silcschedule.c.
480 * Fixed the channel user mode notification sending in server.
481 It was sent point-to-point to the router (or to server by router)
482 but it needs to be destined to a channel. The routines now
483 supports sending the channel user mode notifys to the channels
484 when announcing clients and channels. Affected files are
485 silcd/server.c and silcd/packet_receive.c.
487 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
488 It did not actually replace the old channel entry in the cache.
489 Affected file lib/silcclient/client_notify.c.
491 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Fixed a possible crash in silc_packet_send_prepare. It now
494 assures always that there is enough space in the buffer and
495 at the tail area of the buffer (for MAC).
497 Fixed the inbound buffer reallocation in silc_packet_read.
498 It was old code and did not handle the reallocation correctly.
501 The affected file is lib/silccore/silcpacket.c.
503 * Fixed buffer overflow in silc_parse_nickname in the file
504 lib/silcutil/silcutil.c.
506 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * make install generates new server keys only if there is not
511 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
514 Added check that if the NOREPLY is set then we will not send
515 the away message. This avoids infinite loop of away messages
516 if both clients are away. The affected file is
517 lib/silcclient/client_prvmsg.c.
519 * Fixed client crash if /NICK was given without arguments.
520 Affected file lib/silcclient/command.c.
522 * Server does not send the invite list in INVITE command back
523 to the client if the list was not altered. Added this notion
524 to the protocol spec as well. Affected file silcd/command.c.
526 Fixed possible crash in INVITE command by checking the
527 value of silc_server_get_client_route command.
529 * Fixed the INVITE notify type handling. The arguments are now
530 taken in correct order and client does not crash. The affected
531 file is irssi/src/silc/core/silc-channels.c.
533 Removed the "Inviting xxx to channel" message from the
534 client library away and let the application handle it.
535 Affected file lib/silcclient/command.c. Added that message
536 to Irssi SILC client's message formats.
538 * Fixed CMODE command crash in client. It now checks the
539 amount of arguments correctly and does not crash. The affected
540 file is lib/silcclient/command.c.
542 * Do not create new channel automatically in silc_channels_join
543 but check whether the channel by that name already exists.
544 Affected file irssi/silc/core/silc-channels.c.
546 * Do not send the SERVER_SIGNOFF to router if the disconnected
547 entity was the router. Affected file silcd/server.c.
549 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
550 SILC client as it was missing from there.
552 Added the handling of the KICK notify to the Irssi SILC client
553 as it was missing. Added "you have been kicked" message to
554 Irssi SILC client's message modules formats.
556 Added the handing of the KILL notify to the Irssi SILC client
557 as it was missing. Added the kill message module formats
560 The affected file is irssi/src/silc/core/silc-channels.c.
562 * The router did not save the channel mode the server announced.
563 Affected file silcd/packet_receive.c.
565 * Fixed a possible crash in INFO command in server. If the
566 server did not provide the server info it crashed. Affected
567 file silcd/command.c.
569 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Fixed the GETKEY command in the server to check also the
572 global list. Otherwise the GETKEY would not work correctly
573 in normal SILC server. Affected file silcd/command.c.
575 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Fixed GETKEY crash, it crashed if the command did not succseed.
579 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
582 is now real and not just an macro interface to GMP.
584 Removed the entire GMP from the source tree and imported new
585 NSS MPI library instead. Reason for removing GMP is that it is
586 extremely large and compiles extremely slow. The NSS MPI
587 is only a few files and compiles in less than 10 seconds.
588 The speed is also about the same as GMP. The MPI is imported
591 If the system has GMP installed we will still use the GMP.
592 If it is not then the NSS MPI will be compiled.
594 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Merged a long nickname (127 characters long) crash bugfix from
597 Irssi CVS tree. Affected file irssi/src/core/misc.c.
599 * Merged a freed memory reference bugfix from Irssi CVS tree.
600 Affected file irssi/src/core/commands.c.
602 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Added the server's public key sving and verification to the
605 server when performing the SKE. This was missing and the
606 remote server's (or router's) public key was accepted without
607 checking whether we have it previously or trust it at all.
608 Affected file silcd/protocol.c.
610 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Check in the silc_server_timeout_remote if protocol is active
613 and make sure that the protocol's final callback is called so
614 that all memory if freed. Affected file silcd/server.c.
616 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * silc_server_whois_send_reply crashed the server if the nickname
619 was 127 characters long. Affected file silcd/command.c.
621 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Added sanity check to the silc_server_new_client. If the hostname
624 is provided inside username then check that the provided hostname
625 really is the same as the resolved one. If the hostname was not
626 resolved then check it from the public key. Affected file is
627 silcd/packet_receive.c.
629 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
630 if the server disconnected us and the connection is not valid
631 anymore. Affected file irssi/src/silc/core/silc-channels.c.
633 * Moved the silc_client_[chmode|chumode|chumode_char] away from
634 the library to the lib/silcutil/silcutil.[ch].
636 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Close log file after open. Affected file
639 lib/silcutil/silclog.c.
641 * Check whether sock == NULL in silc_client_send_packet and return
642 if it is. Affected file lib/silcclient/silcclient.c.
644 * Check rec->entry == NULL in the Irssi SILC Client before
645 sending the channel message. Affecte file is
646 irssi/src/silc/core/silc-servers.c.
648 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Merged a splitted window bugfix from Irssi CVS tree. The
651 affected file is irssi/src/fe-text/textbuffer-view.c.
653 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
654 It did not print nickname.
656 * Improved the distributions system a bit.
658 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
661 irssi/src/fe-text/gui-window.c.
663 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
664 to in-active server. The affected file is
665 irssi/src/silc/core/client_ops.c.
667 * Resolve the client in USERS command reply if the entry does
668 not have username resolved. The affected file is
669 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
670 command to WHOIS command to really resolve stuff. The USERS
671 is not used any more in any critical section so WHOIS can
672 be used even though it might be slower than IDENTIFY.
674 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
677 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Changed the protocol API a bit more consistent in the
680 lib/silccore/silcprotocol.[ch].
682 * Changed the following headers to ROBODoc format:
684 lib/silccore/silcpayload.h
685 lib/silccore/silcprotocol.h
686 lib/silccore/silcsockconn.h
688 All core library headers are now formatted.
690 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Fixed a bug in Irssi SILC client; do not show that you are
693 server/router operator if you really are not. Affected file is
694 irssi/src/silc/core/client_ops.c.
696 * Renamed silc_command_free_payload to silc_command_payload_free.
697 Affected file lib/silccore/silccommand.h
699 * Added silcmath.h to include the prototoypes of various routines
700 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
703 * Changed the following headers to ROBODoc format:
705 lib/silccore/silcchannel.h
706 lib/silccore/silccommand.h
707 lib/silccore/silcid.h
708 lib/silccore/silcidcache.h
709 lib/silccore/silcmode.h
710 lib/silccore/silcnotify.h
711 lib/silccore/silcpacket.h
712 lib/silcmath/silcmath.h
714 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Added checking to the server code not to start the server if
717 ciphers and stuff are not configured properly. Affected files
718 silcd/serverconfig.[h] and silcd/server.c.
720 * Changed the layout of the header files of the public interfaces
721 in the SILC libraries. The new layout supports ROBODoc
722 documentation tool (and some others) so that it is easy to create
723 a library reference manual. All the other headers and source
724 code must still follow the CodingStyle document. Also source
725 code must not include these ROBODoc stuffs, only the headers.
726 Furthermore, all public interface headers must now be named
727 by using `silc' prefix, example: silcapi.h, silccipher.h.
728 Some files were renamed due to this. All the other headers
729 must not be used as public interfaces. I will update the
730 CodingStyle document later. Changed following headers, so far:
732 lib/silcclient/silcapi.h
733 lib/silccore/silcauth.h
734 lib/silccore/silcprivate.h
735 lib/silccrypt/silcdh.h
737 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Removed silc_client_packet_send_flush from the client library
742 as it is not needed. Affected file lib/silcclient/client.[ch].
744 * Added printing of message of unresolved authentication method
745 to the Irssi SILC client. Added it to the module formats.
746 Removed the same message from the client library.
748 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Added new distribution feature, DISTLABEL. Every distribution
751 can define own preprocessor label that can be used in the
752 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
753 file distributions, acconfig.h.pre and prepare.
755 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Added Makefile.defines_int to include the actual definitions
758 for Makefile.defines.in. Tested the new distribution system,
759 created distributions and tested installation.
761 * Added AWAY message printing to the Irssi SILC client. Added
762 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
764 * Added SCONNECT command to call the SILC's CONNECT command.
765 Cannot use CONNECT directly since Irssi uses that internally.
766 Affected file irssi/src/silc/core/silc-servers.c.
768 Added ACTION local command. It is same as ME command but takes
769 the channel as mandatory argument.
771 Rewrote some of the Irssi's help files to suite for SILC
774 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Added Makefile.defines[.in] that should for now on be included
777 in all Makefile.am file in the source tree. That file includes
778 all common compilation definitions for SILC source tree.
780 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Minor changes to the ./prepare script to change the package
783 name according the distribution name to the configure.in.
785 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Created new distribution system. Added file `distributions'
788 that defines all the distributions that can be created out of
789 the SILC source tree. The ./prepare script now reads that
790 file to determine how to prepare the distributions. The
791 first argument to the ./prepare is the name of the distribution
792 and second is the version of the distribution. If given
793 without arguments it creates the default (toolkit) distribution
794 with the default version (defined in ./prepare).
796 All Makefile.am files that are subject to the distributions
797 are now named as Makefile.am.pre. These are ./Makefile.am
798 and lib/Makefile.am. Others may be changed later.
800 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Added invite list, ban list, some key management and connection
803 error message printing to module formats in the Irssi SILC client.
805 * Added new silc_client_set_away_message to set the away message
806 that is back to the person who sent private message. The
807 affected file lib/silcclient/silcapi.h and the
808 lib/silcclient/client_prvmsg.c.
810 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Fixed the private message sending in the Irssi SILC client,
813 added local command KEY to the Irssi SILC client.
815 Added key management and key agreement message formats to the
816 irssi/src/fe-common/silc/module-formats.[ch].
818 Added USERS (alias WHO) printing, server/router operator
819 indication and LIST command printing to the module formats.
821 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Fixed channel joining notify handling, cumode notify handling
824 from Irssi SILC client.
826 * Added SILC specific module-formats to the Irssi SILC client so
827 that SILC specific message hilighting, colors etc is possible.
828 Affected file irssi/src/fe-common/silc/module-formats.[ch].
830 Added channel mode, channel user mode, actions, notices,
831 whois and whowas printing to the the module-formats.c.
833 * Fixed a bug in channel deletion in the server. The channel
834 is not left to the cache even if the channel founder auth mode
835 is set when there are no users anymore on the channel. Affected
838 * The silc_net_localhost now resolves the entire hostname including
839 the domain name. Affected file lib/silcutil/silcnet.c.
841 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Changed the ask_passphrase client operation to be ascynchronous.
844 It has now a completion callback and a context that the
845 application must call after it has got the passphrase from
846 the user. Affected files lib/silcclient/silcapi.h,
847 lib/silcclient/protocol.c, lib/silcclient/command.c and
850 Added SilcAskPassphrase callback that the application calls
851 to deliver the passphrase to the library.
853 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
854 The public key verification and especially a certificate
855 verification is asynchronous procedure.
857 Added new SILC_SKE_STATUS_PENDING status to indicate the
858 request is pending and a callback will be called to finalize
861 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
862 indicate that remote end did not send its public key (or
863 certificate), even though we require it. Added check for this
864 condition in the SKE. This was a security bug, now fixed.
866 Defined new SilcSKEVerifyCbCompletion callback that is called
867 when the verification process is completed.
869 The affected files lib/silcske/silcske_status.h and
870 lib/silcske/silcske.[ch].
872 * Changed the verify_public_key client operation to be async
873 as well. Defined SilcVerifyPublicKey callback that is used to
874 indicate the success of the public key verification process.
876 Changed the server and client to use the new async client
879 * Changed the Irssi SILC client's internal scheduler to be called
880 twice as many times as it used to be. As a result the client
881 should be a bit faster now. Affected file is
882 irssi/src/silc/core/silc-core.c.
884 * Added support to Irssi SILC client of asynchronous public key
885 verification and passphrase inquiry. Affected file is
886 irssi/src/silc/core/silc-core.c.
888 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Do not say "You have left channel %s" in client library.
891 Moved it to the application. Affected files are
892 lib/silcclient/command.c and silc/client_ops.c.
894 * Fixed silc_client_get_clients. Command context was not
895 duplicated and was freed memory in the callback. Affected
896 file lib/silcclient/idlist.c.
898 * Do not say "you are now talking..." on JOIN command in the
899 client library. The appliation must handle it.
901 * Do not say ".. changed topic to" in command reply in the
902 client libary. The application must handle it.
904 * Fixed TOPIC command sending in the client library.
906 * Fixed a memory leak in silc_client_command_free in the file
907 lib/silcclient/command.c.
909 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * Imported a modified version of Irssi client to the source tree.
912 The Irssi will be used to create a new client called
913 Irssi SILC. Imported to irssi/.
915 Added silc_core_init_finish function to the Irssi. Affected
916 file irssi/configure.in.
918 A lot changes in the Makefile.ams around the irssi tree.
920 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Do not rehash if the new size is same as the old size of the
923 hash table, in the silc_hash_table_rehash*. The affected file
924 lib/silcutil/silchashtable.c.
926 * Replaced hash_table_del_by_context calls from the server
927 (when channel->user_list and client->channels) to the
928 hash_table_del as it is sufficient and faster.
930 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added silc_hash_table_list, silc_hash_table_get and the
933 SilcHashTableList structure to provide an alternative way to
934 traverse the hash table. The affected files are
935 lib/silcutil/silchashtable.[ch].
937 * Changed the server's idlist routines to use the hash table
938 routines to optimize the code.
940 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Replaced the client entry's `channel' list and channel entry's
943 `user_list' list to hash tables for optimized lookup. Changed
944 the code to use the hash table interface around the code.
945 Affected file lib/silcd/idlist.[ch].
947 * Added `auto_rehash' boolean argument to the function
948 silc_hash_table_alloc to indicate whether the hash table should
949 auto-rehash when it thinks is appropriate time. It will
950 increase the hash table size if the there is twice as much
951 entries in the table than the size of the table, and will
952 decrease the size if there are twice as less entries than
953 the size of the table.
955 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
957 * Fixed silc_xxx_get_supported to not crash at some circumstances.
959 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * silc_idcache_purge_by_context deletes the entry now by context
962 as it is supposed to do. Affected file lib/silccore/idcache.c.
964 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
965 client is not anymore valid (WHOWAS givens the info) and not
966 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
968 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Removed the `data' and `data_len' arguments from the ID Cache
971 interfaces and added `name' argument. ID Cache does not handle
972 anymore the binary data only a names associated with given ID.
974 * When hashing a Client ID with silc_hash_id the entire ID is
975 not hashed anymore, instead only the hash of the Client ID is
976 hashed. This way we can access the Client ID from the cache
977 with Client ID but with the hash of the ID (which is a hash of
978 the nickname) as well without any difference in performance.
980 Added also silc_idcache_find_by_id_one_ext to do one on one
981 searching when we have the actual ID. Added also function
982 silc_hash_client_id_compare. The affected files are
983 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
985 * When hashing the name associated with a ID it is always done
986 in lowercase. This way we can access the cache without worrying
987 about case-sensitivity, even though, for example nicknames are
990 * Fixed a bug in server with channel message sending. It put
991 wrong ID type as destination ID. The affected file
994 * silc_idcache_del_by_context now deletes from all hash tables
995 by context. Affected file lib/silccore/idcache.c.
997 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Changed the client library to use the new ID Cache interface.
1000 Changes around the source tree.
1002 * Added silc_hash_table_rehash_ext to rehash with specific
1003 hash function. Affected file lib/silcutil/silchashtable.[ch].
1005 * Added silc_hash_string_compare to compare two strings in the
1006 hash table. Affected file lib/silcutil/silcutil.[ch].
1008 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added new function silc_idcache_del_by_context into the
1011 lib/silccore/idcache.[ch].
1013 * Changed the server's ID list routines to use the new ID Cache
1014 interface. Changes around the source tree.
1016 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Added silc_hash_table_del[_by_context]_ext functions in to the
1019 lib/silcutil/silchashtable.[ch].
1021 Removed silc_hash_table_find_all* routines and added new
1022 silc_hash_table_find_foreach to replace them.
1024 Added silc_hash_table_replace_ext function as extended
1025 replacing function. Separated the simple hash table interface
1026 from the extended hash table interface in the file
1027 lib/silcutil/silchashtable.h.
1029 * Fixed minor bugs and changed it to use some of the new
1030 hash table functions in lib/silccore/idcache.c
1032 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Added new function silc_hash_table_find_all to return all keys
1035 in the hash table by the specified key. As the hash table is
1036 collision resistant it also makes it possible to have several
1037 duplicate keys in the hash table. This function may be used to
1038 find all of the keys from the hash.
1040 Added user_context arguments to the SilcHashFunction,
1041 SilcHashCompare and SilcHashDestructor to deliver user specified
1044 Added new fuctions silc_hash_table_find[_all]_ext to do
1045 extended lookup with specified hash and compare functions and
1046 specified user contexts.
1048 Added new function silc_hash_table_add_ext to add the key
1049 with specified hash function and user context.
1051 Added new function silc_hash_table_foreach to traverse all
1052 entrys in the hash table. Added SilcHashForeach callback
1055 Added new function silc_hash_table_del_by_context to delete
1056 the entry only if the context associated with the key matches.
1058 Affected files are lib/silcutil/silchashtable.[ch].
1060 * Removed silc_hash_[server/client/channel]_id and added just
1061 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1062 silc_hash_id_compare to compare two ID's using as the hash table
1063 comparison function. Added also silc_hash_data to hash
1064 binary data and silc_hash_data_compare to compare it.
1066 * Removed silc_idlist_find_client_by_hash as it is not needed
1067 anymore. Affected file silcd/idlist.[ch].
1069 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1070 to use internally the SilcHashTable. The new ID Cache is a lot
1071 faster than the old one. Some of the ID Cache interface was also
1072 rewritten and obsolete and stupid functions were removed.
1074 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Added entry_count field to the SilcHashTable to keep the number
1077 of the entries in the table. Implemented the function
1078 silc_hash_table_rehash. Added new function
1079 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1081 Fixed a minor bug in silc_hash_table_free.
1083 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1084 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1085 into the lib/silcutil/silcutil.[ch].
1087 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1089 * Implemented a collision resistant hash table into the
1090 lib/silcutil/silchashtable[ch]. See the header and the source
1091 for the SilcHashTable API.
1093 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Merged dotconf version 1.0.2 into lib/dotconf.
1097 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Do not compile anything in lib/silcsim/* if the SIM support
1100 is not enabled. The tree should now compile without problems
1103 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Compiled the SILC under cygwin. Compiled and tested briefly
1106 without problems. More tests needed. The SIMs didn't compile
1109 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1111 * Fixed possible crash in silc_get_username in the
1112 lib/silcutil/silcutil.c.
1114 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1116 * Fixed a va_arg in silc/client_ops.c.
1118 * Oops, RC5 routines were named AES and caused some problems
1119 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1121 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Added new SilcIDIP structure into the lib/silccore/id.h and
1124 replaced the old `ip' fields from all SILC ID's to that type.
1125 This is a step towards IPv6 support.
1127 The silc_id_get_len takes now the ID as an extra argument.
1128 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1129 both IPv4 and IPv6 based ID's.
1131 The affected files are lib/silccore/id.[ch] and other files
1132 around the tree using these routines.
1134 * Removed the ID length arguments in server from various
1135 silc_server_send_notify_* routines -> they are not needed
1138 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Fixed memory leak in silc_encode_pem_file in the file
1141 lib/silcutil/silcutil.c.
1143 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Check minor version as well in the SKE. Affected files are
1146 silcd/protocol.c and lib/silcclient/protocol.c.
1148 * Added --identifier option to the server so that an identifier
1149 can be when creating the public key for the server. Affected
1150 file is silcd/silcd.c.
1152 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1153 lib/silccrypt/silcpkcs.c.
1155 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Register default ciphers and stuff when using -C option with
1158 the server. Affected file sildc/silcd.c.
1160 * Put back the servers public key filename format, it is better
1161 than the new one. For now, the client keys are saved with the
1162 new filename format. The affected file silc/client_ops.c.
1164 * Implemented the Cipher API for the rest of the ciphers that
1165 did not implement it or implemented it the wrong way.
1167 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Register default ciphers and stuff when using the -S option
1170 in the client. Affected file silc/silc.c. Same also when
1171 creating new key pair with -C option.
1173 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Fixed the silc_verify_public_key client operation function to
1176 save the public keys differently. The fingerprint is now
1177 used as filename and not the hostname. This way also the
1178 client keys are saved uniquely and not with hostnames. The
1179 affected file is silc/client_ops.c.
1181 * Trimmed the silc_hash_fingerprint function to remove extra
1182 whitespaces from the end of the fingerprint. The affected
1183 file is lib/silccrypt/silchash.c.
1187 * Added silc_cipher_register_default function to register all
1188 default ciphers. It can be used when configuration files
1189 does not exist and the application does not want any specific
1190 ciphers in any specific order.
1192 The SilcDList is now used as silc_cipher_list dynamically
1193 allocated cipher list. Removed the static list all together
1194 and now all ciphers must be allocated to the dynamic list.
1195 The silc_cipher_alloc routine was changed to check only the
1198 All silc_cipher_* routines that used to return int returns
1201 The affected files lib/silccrypt/silccrypt.[ch].
1203 * The same thing was done to silc_hash_* as for silc_cipher_*
1204 routines. Affected files lib/silccrypt/silchash.[ch].
1206 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1207 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1208 Added also silc_pkcs_[un]register[_default] functions.
1209 Removed the data_context from the PKCS API.
1211 * Added silc_hmac_register_default function to register default
1212 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1213 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1214 to unregister all hmacs at once.
1216 * Register the default ciphers, hash functions, PKCSs and HMACs
1217 if client's configuration file does not exist. The affected
1220 * The client did not load the hash functions from the SIM
1221 modules at all. Added support for this. Affected file is
1222 silc/clientconfig.c.
1224 * When decoding public key with silc_pkcs_public_key_decode, check
1225 the supported algorithm only if PKCS are registered. Affected
1226 file lib/silccrypt/silcpkcs.c. The same was done with the
1227 silc_pkcs_private_key_decode.
1229 * Fixed the SILC List routines to keep the list always in order.
1230 It used to change the list's order when traversing the list but
1231 not it preserves the order. Affected file lib/trq/silclist.h.
1233 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Added the client library to use the SilcSocketConnection's
1236 reference counter (by silc_socket_dup) to prevent the bug that
1237 the socket object may be freed underneath async operation.
1239 * The name resolv library checking fixes in the configure.in.pre.
1242 * Created new version of the protocol drafts for future
1243 development. The -03 drafts are the ones that will be changed
1244 in the trunk now and the -02 will remain as they are.
1246 * Send list of CUMODE notifys to the router when announcing
1247 the channel users to the router. Affected file silcd/server.c.
1248 If the router receiving channel founder CUMODE for a channel
1249 that already has channel founder it will send CUMODE notify
1250 to the sender to remove the channel founder rights from the
1251 announced client. Affected file silcd/packet_receive.c.
1253 * The CUMODE notify may now use Server ID as well as the entity
1254 who changes the mode. Updated protocool specs.
1256 * Updated INSTALL and README files.
1258 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * New web pages in the http://silc.pspt.fi. The pages was
1265 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Implemented the [DenyConnectin] config section in the server.
1268 Added silc_server_config_denied_conn to check whether incoming
1269 connection is denied. Affected file silcd/serverconfig.[ch].
1271 * Do not check the ports when checking the incoming configuration
1272 data if the port is 0, meaning any. Affected file is
1273 silcd/serverconfig.c.
1275 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Fixed buffer overflow in silc_string_compare in the file
1278 lib/silcutil/silcutil.c.
1280 * Fixed double free in silc_server_command_leave in the file
1283 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Fixed the version checking in the server. Affected file is
1288 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Fixed the configuration data fetching when accepting new
1291 connections in the server. Affected file silcd/server.c.
1293 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1295 * Added `sender_entry' argument to the function
1296 silc_server_packet_relay_to_channel so that we can check
1297 whether some destination actually belongs to the same route
1298 the sender belongs (ie, we must not resend the packet to the
1299 sender). Affected file silcd/packet_send.[ch].
1301 * Added `servername' field to the SilcClientEntry in the server
1302 to hold the name of the server where client is from. Affected
1303 file is silcd/idlist.h.
1305 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Moved the channel message encrypting in the router betwen
1308 router connections from silc_server_channel_message to the
1309 silc_server_packet_relay_to_channel since we want to check
1310 whether we have anybody channel before encrypting anything.
1311 Affected files silcd/packet_[receive/send].c.
1313 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Fixed the [AdminConnection] server config section to support
1316 multiple entries. Affected file silcd/serverconfig.c.
1318 * Added support into the server to check the validity of the
1319 incoming connection before executing any KE or authentication
1322 * The connection configuration is now saved to the KE and
1323 connection auth protocol contexts and not fetched anymore in
1324 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1326 * The local hosts listenning address and port is also resolved
1327 now when starting the server. We want to have the socket object
1328 to include the real address and port for the listener. Added
1329 new function silc_net_check_local_by_sock into the files
1330 lib/silcutil/silcnet.[ch].
1332 * Fixed a broadcast bug in server -> do not broadcast if we
1335 * Fixed a routing bug. Do not route broadcast packets ever.
1336 Broadcast packets must be processed always and not routed since
1337 they may be destined to some other host than yourself and thus
1338 would get routed without no good reason. Affected file is
1341 * Added function silc_server_config_is_primary_route to check
1342 whether primary router connection has been configured (a router
1343 configuration that we are initiating). If there is not, we
1344 will assume that there is only two routers in the SILC network
1345 and we will use the incoming router connection as our primary
1346 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1348 * Changed the order of the broadcasting. Broadcast _after_ the
1349 packet has been processed not before. Affected file is
1352 * Fixed a [ClientConnection] parsing bug. The port was never
1353 parsed correctly thus resulting to port 0. Affected file
1354 silcd/serverconfig.c.
1356 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1357 argument and did not set the broadcast packet flag. Affected
1358 file silcd/packet_send.c. Fixed same bug in the function
1359 silc_server_send_notify as well.
1361 * If we receive NEW_ID packet for our own ID in the server, ignore
1364 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Removed the nickname from the Private Message Payload.
1369 Updated the code and the protocol specs.
1371 * Updated protocol specs for submitting to the IETF.
1373 * Tweaked the Random Number Generator a bit. Affected file
1374 lib/silccrypt/silcrng.c. Exported a new function
1375 silc_rng_[global]_add_noise which can be used to add more
1378 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Do not parse packets with different timeout when protocol
1381 is active -> may cause problem with rekey. Affected file
1384 * When server receives signoff notify it must not create
1385 new channel key if the client is on any channels since the
1386 sender of the signoff notify will create it.
1388 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Added printing of error messages during SKE protocol from the
1391 failure packet sent by server during SKE. Affected file
1394 * Removed the client's failure_callback handling with timeout
1395 and handle it immediately when received.
1397 * The SKE library returned wrong type in SUCCESS and FAILURE
1398 packets. They must be 32 bit MSB not 16 bit MSB.
1400 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Ok, rewrote the logic of the re-key and now it seems to work.
1403 I tested it on high traffic with frequent re-keys without
1404 problems. Added hmac_receive (and renamed hmac to hmac_send)
1405 in SilcClientConnection in lib/silcclient/client.h and
1406 in SilcIDListData in silcd/idlist.h. Also, removed the
1407 SilcPacketParserContext's cipher and hmac fields as they are
1408 not needed anymore and actually caused some problems when
1409 the ciphers and hmac's changed underneath the packet parser.
1411 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * If re-key protocol is active then process the incoming packets
1414 synchronously since we must assure that icoming packets encrypted
1415 with the old key is processed before the new keys is set to
1416 use. This is true other packets than for REKEY packets.
1417 Affected file silcd/server.c. The same was done to client library
1418 as well, affected file lib/silcclient/client.c.
1420 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1422 * Fixed bug in client and server to accept the force send if
1423 the packet is send from silc_[server/client]_packet_process
1424 function. Otherwise the packets are never delivered, oops.
1426 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Disable force sending of packets when REKEY protocol is active.
1429 We must assure that no packet is sent directly when rekey is
1430 performed. All packets must be sent through packet queue.
1431 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1432 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1433 function is silc_[server/client]_packet_send_real to check
1436 * Replaced the SIM paths from example config files to
1437 /usr/local/modules. Also, make install creates now
1438 /usr/local/silc/logs directory to hold all the SILC server
1441 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Made the configure.in.pre work on Solaris. Patch by salo.
1445 * Made all ciphers compatible with non-x86 machines. Defined
1446 CBC mode macros into lib/silccrypt/ciphers_def.h.
1448 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Fixed the make install.
1452 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * When MAC computation fails the silc_packet_decrypt returned 0
1455 even though it was supposed to return -1. Fixed this. The
1456 affected file is lib/silccore/silcpacket.c.
1458 * Do not replace the config files in /etc/silc (in make install)
1459 if they already exist. Affected file ./Makefile.am.
1461 * Do not send re-key packets immediately but through packet queue.
1462 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1464 * Changed silc_net_check_host_by_sock to return FALSE if the
1465 IP/DNS could not be resolved. Though, it returns the IP address
1466 now even if it could not resolve it (but returns also FALSE).
1467 Affected file lib/silcutil/silcnet.[ch].
1469 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Added silc_pkcs_decode_identifier to decode the public key's
1472 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1473 Added also silc_pkcs_free_identifier. Added also new context
1474 SilcPublicKeyIdentifier.
1476 * Added -S option to the silc client. It is used to dump the
1477 contents of the specified public key file.
1479 * Changed the PKCS api to return the public key length when
1480 setting the public key.
1482 * Fixed a fatal bug in the public and private key file loading.
1483 Affected file lib/silccrypt/silcpkcs.c.
1485 * Execute the packet parsing for client with zero (0) timeout
1486 if the protocol is active. Affected file silcd/server.c.
1488 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Made the key generation options to the silcd program. Added
1491 -C option, equivalent to client's option.
1493 * Added new [ServerKeys] config section to the server. It
1494 configures the server's public and private key.
1496 * Defined generic Public Key Payload into the protocol
1497 specification to send specific type of public keys and
1500 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1501 public key or certificate.
1503 * Implemented the GETKEY command to the server and to the
1504 client library and on user interface.
1506 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Made preliminary `make install' work.

1538 lib/silcclient/client.h.
1542 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Do not ask whether user wants to use the negotiated private key
1545 for private messages, just use it. Affected file is
1546 silc/local_command.c.
1548 * Added `send_enc_key' and `enc_key_len' fields to the
1549 SilcIDListData structure since they are needed in the re-key
1550 phase. Affected file is silcd/idlist.[ch].

1569 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1570 int64 of at least the xintXX size. If void * is less that 4
1571 bytes uint32 * will be used. Defined bool as boolean.
1573 * Changed _ALL_ unsigned long and unsigned int to uint32,
1574 unsgined short to uint16 in the source tree.
1576 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1577 not handle clients that has entry->data.registered == FALSE.
1578 They are not in the network anymore. Affected file is
1581 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Implemented the sending of the SERVER_SIGNOFF notify in the
1584 server. Affected file is silcd/server.c.
1586 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

1595 implemnted the printing of the SERVER_SIGNOFF info to the
1596 application. Affected file silc/client_ops.c.
1598 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1599 if the deleting was successful. Affected file silcd/idlist.[ch].
1601 * Added support for public key authentication in the connection
1602 authentication protocol in the client library. Affected file
1603 lib/silcclient/protocol.c.
1605 * Changed the server's silc_idlist_get_clients_by_* interface
1606 to support already allocated array so that new entries may be
1607 added to pre-allocated array. Affected file silcd/idlist.[ch].
1608 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1609 and command replies.
1611 * All command reply functions in the server now calls the
1612 pending command callback even if error occured. This way the
1613 error will be delivered to the client as well. Affected files
1614 silcd/command.c and silcd/command_reply.c.
1616 * Fixed INFO command to return local server's info if no server
1617 was provided. Affected file lib/silcclient/command.c.
1619 * Removed RESTART command for good. Updated the code and the

1636 only by the router and is done once in an hour. Added `rekey'
1637 field to the SilcChannelEntry in the server. Affected files
1638 silcd/server.c and silcd/idlist.h.
1640 * Added silc_task_unregister_by_context into the file
1641 lib/silcutil/silctask.[ch].
1643 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Added SILC_UMODE_GONE mode to indicate when the client is not
1646 present in the SILC network. Added also support to the local
1647 command AWAY that will set this mode. Added support of showing
1648 "xxx is gone" in WHOIS command. The USERS command shows the
1649 gone status as well.
1651 * Fixed setting server and router operator privileges in the
1652 server's UMODE command. Affected file silcd/command.c.
1654 * Merged the SKE KE1 and KE2 payloads into one payload. The
1655 new KE payload is equivalent to the old KE2 payload.
1657 Cleaned up the SKE Start Payload parsing. It now uses the
1658 simple buffer unformatting to do the parsing. A lot faster
1661 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1662 to the SKE that is used to indicate whether both of the SKE
1663 parties should perform authentication. By default only the
1664 responder performs authentication. By setting this flag also
1665 the initiator must do authentication. By default it is unset
1666 since in normal SKE case, client to server connection, only
1667 the responder should do authentication. When doing SKE between
1668 two clients both should perform authentication. Updated the
1669 code and the protocol specs.
1671 * A little fix to IDENTIFY command in the server. Search the
1672 client first by hash not nickname. Affected file is
1675 * Fixed the silc_client_close_connection to support closing
1676 the client to client connections wihtout deleting too much
1677 data. Affected file lib/silcclient/client.c.
1679 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1680 are received if protocol used to be active but is not anymore
1681 the application would crash due to NULL pointer dereference.
1682 Affected files silcd/server.c and lib/silcclient/client.c.
1684 * Added `hash' field to the SilcClientConnection to include
1685 the hash function negotiated in the SKE protocol.
1687 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1688 to set the channel founder authentication data. A client can
1689 claim the founder rights later by providing the authentication
1690 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1691 This way the channel founder can regain the channel founder
1692 privileges even it is left the channel. This works only on
1693 local server and the client must be connected to the same
1694 server to be able to regain the founder rights. Updated the
1695 protocol specs accordingly.
1697 Added support to the CMODE command in the client to set the
1698 founder auth data. Read the README to see how to set it.
1700 Added support to the CUMODE command to claim the founder
1701 rights. Read the README to see how to do it.
1703 Added support for the founder authentication to the Channel
1704 Entry in the server. Affected file silcd/idlist.h.
1706 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1707 server's CMODE command. Affected file silcd/command.c.
1709 * Added the following new functions into lib/silccore/silcauth.[ch]:
1710 silc_auth_get_method and silc_auth_get_data.
1712 * The server now saves the remote hosts public key to the
1713 SilcIDListData pointer. Affected file silcd/protocol.c.
1715 * The normal server now does not remove the channel entry from
1716 the cache if the founder authentication data is set. It used
1717 to remove it if the founder was the last one on the channel on
1718 the server and left the channel. The auth data is saved and
1719 if the channel is re-joined later the old entry is used with
1720 the old auth data. Affected files silcd/command_reply.c and
1723 * Removed the `pkcs' field from the SilcIDListData structure
1724 in the server; it is not used. Affected file silcd/idlist.h.
1726 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Fixed packet processing on slow links. Partial packets were
1729 never re-processed because the incoming data buffer was cleared
1730 by the application. Application must not directly clear the
1731 sock->inbuf, the packet processing routines handle it. Fixed
1732 this in client library and in server.
1734 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Fixed the WHOIS and IDENTIFY send reply function to really
1737 check whether to send list or just one entry. Affected file
1740 * Cleaned up the LEAVE command's channel key distribution. The
1741 affected file silcd/command.c.
1743 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1744 can enforce the channel mode as well. In that case the ID
1745 includes the ID of the server. The code now enforces the
1746 mode change if the router have different mode than the server.
1748 * The notify client operation with CMODE_CHANGE notify can now
1749 return NULL client_entry pointer if the CMODE was not changed
1750 by client. Application must check for this.
1752 * Added <Server ID> argument to INFO command to support server
1753 info fetching by Server ID.
1755 * Added silc_server_announce_get_channel_users to get assembled
1756 packets of channel users of the specified channel. Affected
1757 file silcd/server.[ch].
1759 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1760 was freed underneath the ID Cache.
1762 * Re-announce clients when the server received CHANNEL_CHANGE
1763 notify from the router. Affected file silcd/packet_send.c.
1765 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1768 crashed since it did not handle the fact that there is no cipher
1769 called "3" and didn't check the error condition. Now fixed.
1771 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1772 flag. It can be used to send message requests.
1774 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Implemented the RESTART command in the client.
1778 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1779 notice type messages. Added notice printing to the user
1782 * The channel keys are not re-generated if the channel's mode
1783 is PRIVKEY, ie private key on the channel exists. Affected
1784 files silcd/server.c and silcd/command.c.
1786 * Fixed a little bug in channel message delivery when channel
1787 private keys are set in the server. Affected file is
1788 silcd/packet_send.c.
1790 * Changed the setting on channel->on_channel = TRUE from the
1791 silc_client_save_channel_key to the JOIN command reply. The
1792 key payload is not received if the private channel key is set.
1793 Affected file lib/silcclient/command_reply.c and the
1794 lib/silcclient/client_channel.c.
1796 * When the CMODE_CHANGE notify is sent and the channel private
1797 key mode is removed the channel key must be re-generated in
1798 other cells as well. Added this support for the router in the
1799 silcd/packet_receive.c.
1801 * Added new local command NOTICE to send notice message on
1802 channel. Affected file silc/local_command.[ch].
1804 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Added new local command ME to the client. It is used to send
1807 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1808 some action. Affected file silc/local_command.[ch].
1810 * Changed channel_message and private_message client operations
1811 to deliver the message flags to the application. Added also
1812 the `flags' arguments to the silc_client_send_channel_message
1813 and silc_client_send_private_message functions. Affected file
1816 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Redefined the Private Message Payload to support private message
1819 keys and to support the new private message flags. Updated
1820 the protocol specs. Flags makes it possible to have for example
1821 CTCP style messages.
1823 * Added new type SilcPrivateMessagePayload and defined an API
1824 for it in the lib/silcclient/silcprivate.[ch].
1826 * Tested private message private keys successfully. Tested the
1827 private message key set, unset and list commands with the new
1830 * Redefined the Channel Message Payload to include the channel
1831 message flags (equal with private message flags) to support
1832 for example CTCP style messages.
1834 * Defined some of the message (for channel and private message)
1835 flags. Updated the protocol specs and added the flags to the
1836 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1838 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Added SilcKeyAgreementStatus type to the key agreement routines
1841 to indicate the current status and error if one occured.
1842 The status types are defined in the lib/silcclient/silcapi.h.
1844 * Added new local command KEY that is used to set and unset private
1845 keys for channels, set and unset private keys for private messages
1846 with remote clients and to send key agreement requests and
1847 negotiate the key agreement protocol with remote client. The
1848 key agreement is supported only to negotiate private message keys,
1849 it currently cannot be used to negotiate private keys for channels,
1850 as it is not convenient for that purpose.
1852 * Fixed a minor pending callback setting bug in the function
1853 silc_client_get_client_by_id_resolve, now the function works.
1854 Affected file lib/silcclient/idlist.c.
1856 * Added function silc_net_get_local_port to get local bound
1857 port by socket. Added to lib/silcutil/silcnet.[ch].
1859 * Added `sockets' and `sockets_count' fields to the SilcClient
1860 object. They hold the sockets of the listenning sockets in
1861 the client. Listenning sockets may be for example the key
1862 agreement server. Affected file lib/silcclient/client.[ch].
1863 Added functions the silc_client_add_socket and the
1864 silc_client_del_socket. They are exported to the application
1867 * Added ~./silc/clientkeys to support other client's public keys.
1869 * Renamed verify_server_key client operation to verify_public_key
1870 and added one argument to indicate the type of the connection
1871 (server, client etc.).
1873 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1875 * Added silc_server_connection_auth_request to handle the
1876 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1877 silcd/packet_receive.[ch].
1879 * Added silc_server_send_connection_auth_request into the
1880 silcd/packet_send.c to send the connection auth request packet.
1882 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1885 * Fixed the public key authentication in responder side in the
1886 server. The `auth_data' pointer includes the SilcPublicKey
1887 not the path to the public key. Affected file silcd/protocol.c.
1889 * Implemented the public key authentication in the initiator side
1890 in the server. Affected file silcd/protocol.c.
1892 * Removed the [RedirectClient] config section from the server
1893 configuration. Is not needed and I don't want to implement it.
1895 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Cleaned up the CMODE command in the server. It now works
1898 correctly and supports all the modes defined in the protocol.
1899 Affected file is silcd/command.c.
1901 * Added `hmac_name' field to the SilcChannelEntry in the server
1902 to hold the default HMAC of the channel. It can be set when
1903 creating the channel (with JOIN command). Affected files
1906 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1907 type to indicate the change of the current cipher and hmac
1908 on the channel. Client can safely ignore the <cipher> argument
1909 (if it chooses to do so) since the CHANNEL_KEY packet will
1910 force the channel key change anyway. The <hmac> argument is
1911 important since the client is responsible of setting the new
1912 HMAC and the hmac key into use.
1914 * Fixed the CMODE command in the client library as well.
1916 * Tested CMODE command in router environment successfully.
1918 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Show the version of the remote client (or server) when connecting
1921 to the server. It is logged to the log file. Affected file
1922 is silcd/protocol.c.
1924 * Fixed the KILLED notify handling in the client library. The
1925 client must be removed from all channels when receiving the
1928 Also, do not remove the client entry when giving the KILL
1929 command but when the KILLED notify is received.
1931 * Removed silc_idlist_find_client_by_nickname from the server.
1932 Not needed anymore. Affected files silcd/idlist.[ch].
1934 * Implemented the CHANNEL_CHANGE notify type handling to the
1935 server. Affected file silcd/server.c.
1939 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Added silc_server_send_notify_invite to send the INVITE
1942 notify between routers.
1944 * Implemented the INVITE command correctly to the server.
1946 * Implemented the INVITE notify type handling in the server.
1948 * Implemented the INVITE command to the client library and on the
1951 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Added function silc_server_get_client_resolve to find the
1954 client entry by ID from all ID lists and then resolve it
1955 (using WHOIS) if it cannot be found. Affected file is
1958 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Implemented the BAN command to the client library.
1962 * The JOIN command in the server now checks the invite list
1965 * Changed the silc_command_reply_payload_encode_va and the
1966 silc_command_payload_encode_va to support that if argument is
1967 NULL it ignores and checks the next argument. Affected file
1968 lib/silccore/silccommand.c.
1970 * Added silc_server_send_notify_ban to send the BAN notify
1971 type between routers.
1973 * Chaned the silc_notify_payload_encode to support that if
1974 argument is NULL it ignores and checks the next argument.
1975 Affected file lib/silccore/silcnotify.c.
1977 * Tested ban lists in router environment successfully.
1979 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Implemented BAN command to the server, in silcd/command.[ch].
1983 * Removed the BAN and INVITE_LIST modes from the CMODE command
1986 * Added function silc_string_match to regex match two strings.
1987 Affected files lib/silcutil/silcutil.[ch].
1989 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Redefined parts of the SilcChannelEntry in the server to support
1992 the new ban and invite lists.
1994 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Redefined the INVITE command. The same command can be used to
1997 invite individuals to the channel but also to manage the invite
1998 list of the channel (to add to and remove from the invite list).
1999 Updated the protocol specs.
2001 * Added new command SILC_COMMAND_BAN that can be used to manage
2002 the ban list of the channel. Updated the protocol specs.
2004 * Removed the channel modes: the SILC_CMODE_BAN and the
2005 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2006 in the CMODE command. The equivalent features are now available
2007 using INVITE and BAN commands. Updated the protocol specs.
2009 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2010 in the network about change in the current ban list. The notify
2011 type is not used by the client.
2013 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2014 support the invite lists.
2016 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Added new function silc_string_regexify that converts string
2019 including wildcard characters into regex string that can
2020 be used by the GNU regex library. Added into the file
2021 lib/silcutil/silcutil.[ch].
2023 Added silc_string_regex_combine to combine to regex strings
2024 into one so that they can be used as one regex string by
2025 the GNU regex library. Added into the file
2026 lib/silcutil/silcutil.[ch].
2028 Added silc_string_regex_match to match two strings. It returns
2029 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2031 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2033 * Imported GNU regex to the soruce tree into lib/contrib.
2034 Fixed some compiler warning from the regex.c.
2036 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Fixed MOTD command in the server to work in router environment.
2040 * Fixed the MOTD command in the client library to support
2041 the server argument in the command.
2043 * Added `nickname_len' argument to the silc_idlist_add_client
2044 in the server, as the `nickname' argument may be binary data
2047 * Added silc_idlist_get_channels to return all channels from
2050 * Implemented LIST command to the server. Affected file is
2053 * Implemented the LIST command to the client library and on the
2056 * Added [<user count>] argument to the LIST command reply.
2057 With private channels the user count is not shown.
2059 * Updated TODO and README.
2061 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * The client entry's data.registered must be TRUE even with
2064 global client entry on global client list. The data.registered
2065 is used to check whether the client is anymore in the network,
2066 for example with WHOWAS command so it must be valid.
2068 * Fixed the WHOWAS command in the server. It now actually works
2069 in router environment. Added function into silcd/command_reply.c
2070 silc_server_command_reply_whowas_save.
2072 * Added silc_idlist_purge function to the silcd/idlist.c
2073 to periodically purge the ID Cache.
2075 * Fixed INFO command in the server. It works now in router
2076 environment. Added <server name> argument to the INFO command
2077 reply. Updated the protocol specs.
2079 * Fixed minor bug in silc_idcache_purge to not purge if the
2080 expire value is zero.
2082 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2083 they were buggy because of the WHOWAS information.
2085 * Fixed local command MSG to handle the async resolving of
2086 the remote client properly. It used to fail the first MSG.
2087 Affected file silc/local_command.c.
2089 * Added `data_len' field to SilcIDCache context.
2091 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Update TODO. Todo in commands in the server.
2095 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2098 used by routers as broadcast packet to inform other routers
2099 about the changed user mode.
2101 Implemented the notify handling in the server. Affected file is
2102 silcd/packet_receive.c. Added the function
2103 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2105 * Added new generic Channel Payload and deprecated the New Channel
2106 Payload. The New Channel Payload is now the generic Channel
2109 * Added new argument `mode' to the silc_server_send_new_channel
2110 as it is required in the Channel Payload now.
2112 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2113 and created a new and real SilChannelPayload to represent the
2114 new generic Channel Payload. Implemented the encode/decode
2115 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2117 * Added silc_server_get_client_channel_list to return the list
2118 of channels the client has joined for WHOIS command reply.
2119 Affected file silcd/server.[ch].
2121 * Implemented the channel list sending in the WHOIS command reply
2122 in server and in the client.
2124 Implemented the channel list displaying on the user interface
2125 as well. Affected file silc/client_ops.c.
2127 * Added silc_channel_payload_parse_list to parse list of Channel
2128 Payloads. It returns SilcDList list of SilcChannelPayloads.
2129 Client for example can use this function to parse the list of
2130 channels it receives in the WHOIS command reply. The caller
2131 must free the list by calling silc_channel_payload_list_free.
2132 Affected files lib/silccore/silcchannel.[ch].
2134 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Added one new argument <user mode> to the WHOIS command reply
2137 to return the mode of the user in SILC. Updated the protocol
2140 Implemented it to the server and client.
2142 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Fixed the mode printing on the user interface on joining.
2145 Affected file silc/client_ops.c.
2147 * Implemented the UMODE command and user modes in general to the
2148 client library and to the user interface.
2150 * Implemented the UMODE command to the server.
2152 * The server now sends UNKNOWN_COMMAND error status if client sends
2153 unknown command. Affected file silcd/command.c.
2155 * All server commands now handle the command identifier the right
2156 way when sending the command reply to the client. The client can
2157 use to identify the command replies with the identifier.
2159 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Added silc_server_get_client_route to resolve the route to
2162 the client indicated by the client ID. Affected file is
2165 * Added silc_server_relay_packet as general function to relay
2166 packet to arbitrary destination. This deprecates functions
2167 like _send_private_message_key, _relay_notify etc. Affected
2168 file is silcd/packet_send.[ch].
2170 Removed silc_server_send_key_agreement,
2171 silc_server_send_private_message_key and
2172 silc_server_packet_relay_notify functions from the file
2173 silcd/packet_send.[ch].
2177 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2178 server. Affected file silcd/packet_receive.[ch].
2180 * Implemented the KILL command to the client. Implemented the
2181 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2182 Affected files lib/silcclient/command[_reply].c and
2183 lib/silcclient/client_notify.c. Implemented the KILL notify
2184 printing in the user inteface.
2186 * Fixed a lot silc_parse_nick memory leaks from the client
2187 library in the file lib/silcclient/command.c.
2189 * Changed the silc_server_send_notify_on_channels's `sender'
2190 argument from SilcSocketConnection to SilcClientEntry to
2191 check the sender as entry and not as connection object and not
2192 to send to the client provided as argument. The affected file
2193 is silcd/packet_send.[ch].
2195 * The notify packets that are destined directly to the client used
2196 to not to be processed by the server. Now changed that and the
2197 server processes all notify packets. After relaying the packet
2198 to the client the notify packet is processed in the server.
2200 * The silc_server_free_client_data now checks whether there is
2201 pending outgoing traffic for the client and purges the data to
2202 the network before removing the client entry.
2204 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2207 an client is killed from the SILC Network. Updated the protocol
2210 Added new function silc_server_send_notify_killed to the
2211 silcd/packet_send.[ch].
2213 * Added function silc_server_packet_relay_notify to relay notify
2214 packets that are destined directly to a client. In this case
2215 the server does not process the notify packets but merely relays
2216 it to the client. Affected file silcd/packet_send.[ch].
2218 Added also silc_server_packet_process_relay_notify to check
2219 whereto relay the notify. Affected file is
2220 silcd/packet_receive.[ch].
2222 * Implemented the KILL command to the server.
2226 * Added the backup schema desgined last fall to the protocol
2227 specs for everyone to see. The specification is in the
2228 *-spec-xx.txt draft and the packet type definitions for the
2229 backup routers is in *-pp-xx.txt draft. Thusly, added also
2230 new packet type SILC_PACKET_CELL_ROUTERS.
2232 * A big security problem in the implementation discovered. The
2233 signoff of an client did not cause new channel key generation
2234 which it of course should've done. The channel keys must be
2235 always re-generated when client leaves (or signoffs) the channel.
2236 The silc_server_remove_from_channels funtion now handles
2237 the channel key re-generation.
2239 * Added `sender' argument to the silc_server_send_notify_on_channels
2240 to not to send the client provided as argument. Affected file
2241 silcd/packet_send.[ch].
2243 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Implemented OPER and SILCOPER commands into the server and
2248 * Added silc_auth_verify and silc_auth_verify_data to verify
2249 the authentication directly from the authentication payload.
2250 It supports verifying both passphrase and public key based
2251 authentication. Affected file lib/silccore/silcauth.[ch].
2253 * Added `hash' field to the SilcIDListData structure. It is the
2254 hash negotiated in the SKE protocol. Affected file is
2257 * Slight redesigning of the SilcAuthPayload handling routines.
2258 Do not send SilcPKCS but SilcPublicKey as argument.
2260 * Implemented the public key authentication support to the
2261 serverconfig. The public key is loaded from the provided path
2262 and saved as authentication data to void * pointer. Thus,
2263 changed the unsigned char *auth_data to void *auth_data;
2265 * Fixed SHUTDOWN command to send the reply before the server
2266 is shutdown. :) Affected file silcd/command.c.
2268 * Fixed fatal bug in CONNECT command. The hostname was invalid
2269 memory and server crashed. Affected file silcd/command.c.
2271 * Fixed fatal bug in CLOSE command. The server_entry became
2272 invalid but was referenced later in the command. Affected file
2275 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Fixed fatal bug in failure packet handling. Server ignored
2278 the failure and thus crashed when it came.
2282 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2285 that the command may be executed only once in (about) 2 seconds.
2286 The old SILC_CF_LAG flag is same but allows command bursts up
2287 to five before limiting.
2289 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2290 server code. Various commands now includes the CF_LAG_STRICT
2291 flag to disallow any kind of miss-use of the command.
2293 * Fixed the silc_buffer_unformat to not to allocate any data
2294 if the length of the data is zero. It used to allocate the
2295 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2297 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Changed the format of AdminConnection configuration section
2300 in the server. Added username of the admin to the format.
2301 Affected files silcd/serverconfig.[ch].
2303 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2304 to return admin configuration data by host, username and/or
2307 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Implemented WHOWAS command to the server. Added the functions:
2311 silc_server_command_whowas_parse,
2312 silc_server_command_whowas_send_reply,
2313 silc_server_command_whowas_from_client and
2314 silc_server_command_whowas_from_server
2316 * Added <Client ID> argument to the WHOWAS command reply. Updated
2317 the protocol specs accordingly.
2319 * Implemented WHOWAS command and command_reply to the client
2322 Implemented the WHOWAS printing on the user interface.
2324 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Added new argument to the WHOWAS command reply, the real name.
2327 It is an optional argument. Updated the protocol specs.
2329 * Added SilcIDCacheDestructor callback that is registered when
2330 the SilcIDCache is allocated. The callback is called when
2331 an cache entry in the ID Cache expires, or is purged from the
2332 cache. Added into lib/silccore/idcache.[ch].
2334 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2335 to destruct the client entries when the cache entry expires.
2336 Other ID Cache's in server and in the client library ignores
2339 * If the ID Cache entry's `expire' field is zero then the entry
2340 never expires. Added boolean `expire' argument to the
2341 silc_idcache_add function in the lib/silccore/idcache.[ch].
2342 If it is TRUE the default expiry value is used.
2344 * Added silc_server_free_client_data_timeout that is registered
2345 when client disconnects. By default for 5 minutes we preserve
2346 the client entry for history - for WHOWAS command.
2348 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * Added support to the server to enforce that commands are not
2351 executed more than once in 2 seconds. If server receives
2352 commands from client more frequently, timeout is registered
2353 to process the commands. Affected file silcd/command.c.
2354 Added new function silc_server_command_process_timeout.
2356 * Changed NICK_NOTIFY handling in client library to check that
2357 if the client's nickname was changed, so there is no need to
2358 resolve anything from the server.
2360 * Removed error printing from the WHOIS and IDENTIFY commands.
2361 If error occurs then it is ignored silently in the client library.
2362 The application, however, may map the received error to
2363 human readable error string. The application currently maps
2364 the NO_SUCH_NICKNAME error to string.
2366 * Made the command status message public to the application. Moved
2367 them from lib/silcclient/command_reply.c to
2368 lib/silcclient/command_reply.h. The application can map the
2369 received command status to the string with the
2370 silc_client_command_status_message function.
2372 * Added check to the server to check that client's ID is same
2373 as the Source ID in the packet the client sent. They must
2376 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Added dist-bzip hook to the Makefile.am to make bzip2
2379 compressed distributions.
2381 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2383 * Server now enforces the maximum length for the nickname and
2384 the channel as protocol specification dictates. 128 bytes for
2385 nickname and 256 bytes for channel name.
2387 * Moved the WHOIS printing to the application. The client libary
2388 does not print out the WHOIS information anymore, the application
2389 must do it. Renamed silc_client_command_reply_whois_print to
2390 the silc_client_command_reply_whois_save.
2392 The client's idle time is also sent to the application now, and
2393 the idle is shown on screen.
2395 * Added silc_client_command_reply_identify_save to save the
2396 received IDENTIFY entries.
2398 * Do not check for channel private keys in message sending and
2399 reception if the channel does not have the PRIVKEY mode set.
2400 Affected file lib/silclient/client_channel.c.
2402 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2405 just surfaced after chaning the JOIN procedure.
2407 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Added silc_client_get_clients_by_list to get client entries
2410 from Client ID list, that is returned for example by JOIN
2411 and USERS command replies. The application should use this
2412 function for example when JOIN command reply is received to
2413 resolve the clients already on the channel (library does not
2414 do that anymore as USERS command reply is not used in the JOIN
2415 procedure anymore). Affected files lib/silcclient/silcapi.h and
2416 lib/silcclient/idlist.c.
2418 * JOIN command reply and USERS command reply returns now SilcBuffer
2419 pointers instead of unsigned char pointers when returning
2420 the client list and mode list.
2422 * Added <Client ID> argument to the JOIN command reply, mainly
2423 for the server to identify for which client the command was
2424 originally sent. Updated protocol specs accordingly.
2426 * Added SilcDlist private_key pointer to the SilcChannelEntry
2427 in the client to support the channel private keys. Affected
2428 file is lib/silcclient/idlist.h.
2430 * Added SilcChannelPrivateKey argument to the function
2431 silc_client_send_channel_message so that application can choose
2432 to use specific private ke if it wants to. If it is not provided,
2433 the normal channel key is used, unless private keys are set.
2434 In this case the first (key that was added first) is used
2435 as the encryption key.
2437 * Implemented the support for channel private key handling.
2438 Implemented the following functions:
2440 silc_client_add_channel_private_key,
2441 silc_client_del_channel_private_keys,
2442 silc_client_del_channel_private_key,
2443 silc_client_list_channel_private_keys and
2444 silc_client_free_channel_private_keys
2446 Affected file lib/silcclient/client_channel.c.
2448 * Added the support for the private keys in the channel message
2449 sending and encryption and in the message reception and
2450 decryption. Affected funtions are
2451 silc_client_send_channel_message and silc_client_channel_message.
2453 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * Added SKE's key verify callback to the client library's
2456 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2458 * Removed the statement that server (or router) must send USERS
2459 command reply when joining to the channel so that the client
2460 knows who are on the channel. Instead, the client list and
2461 client's mode list is now sent in the JOIN command reply to the
2462 client who joined channel. This is better solution.
2464 * Added function silc_server_get_users_on_channel and function
2465 silc_server_save_users_on_channel to the silcd/server.[ch].
2467 * Removed function silc_server_command_send_users from the
2470 * Do not show topic on the client library anymore. The topic is
2471 sent in the command reply notify to the application and the
2472 application must show the topic now.
2474 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Added client searching by nickname hash into the IDENTIFY and
2477 WHOIS commands in the server as they were clearly missing from
2478 them. Affected file is silcd/command.c.
2480 * Fixed a bug in private message receiving in the client library.
2481 The remote ID was freed and it wasn't supposed, now it is
2484 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Minor fix to the channel payload; allocate the data area, as it
2487 needs to be of specific length.
2489 * If the key agreement port is zero then the operating
2490 system will define the bound port. Affected files are
2491 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2493 * Added new function silc_channel_payload_decrypt into the file
2494 lib/silccore/silcchannel.[ch].
2496 * Moved the channel message etc, check from silc_packet_decrypt
2497 to applications. The library calls now a generic
2498 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2499 when the packet is either normal or special. This was done to
2500 allow more wide range of checking that was not allowed when
2501 the code was in library. Now applications can do virtually any
2502 checks to the packet and return to the library the decision how
2503 the packet should be processed. Affected files are
2504 lib/silccore/silcpacket.[ch].
2506 Added silc_server_packet_decrypt_check to the server and
2507 silc_client_packet_decrypt_check to the client library.
2509 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2510 to send with specified source and destination information.
2512 * Channel message delivery between routers was broken after the
2513 channel key distribution was fixed earlier. The channel key
2514 was used be to distributed to other routers as well which is not
2515 allowed by the protocol. Now this is fixed and channel keys
2516 really are cell specific and the channel message delivery between
2517 routers comply with the protocol specification.
2519 * Fixed various commands in server to check also the global list
2520 for the channel entry and not just the local list. The affected
2521 file silcd/command.c.
2523 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Added assert()s to buffer formatting and unformatting routines
2526 to assert (if --enable-debug) when error occurs. Affected
2527 file: lib/silcutil/silcbuffmt.c.
2529 * Changed to auto-reconnect to check whether the remote host is
2530 router and register the re-connect timeout if it is. It used
2531 to check that whether we are normal server, but router must do
2532 auto-reconnect with another router as well. Affected file
2535 * Removed the [<key len>] option from CMODE command as the cipher
2536 name decides the key length, nowadays. See the defined ciphers
2537 from the protocol specification.
2539 * Added [<hmac>] option to the CMODE command to define the HMAC
2540 for the channel. Added SILC_CMODE_HMAC channel mode.
2542 * Added [<hmac>] option for the JOIN command so that user can
2543 select which HMAC is used to compute the MACs of the channel
2546 * Added Hmac field to the Channel Message Payload. The integrity
2547 of plaintext channel messages are now protected by computing
2548 MAC of the message and attaching the MAC to the payload. The
2549 MAC is encrypted. Now, it is clear that this causes some
2550 overhead to the size of the packet but rationale for this is that
2551 now the receiver can verify whether the channel message decrypted
2552 correctly and also when private keys are set for the channel the
2553 receiver can decrypt the packet with several keys and check from
2554 the MAC which key decrypted the message correctly.
2556 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2557 lib/silccrypt/silccipher.[ch].
2559 * Added silc_hash_len to return the digest length into the
2560 lib/silcrypt/silchash.[ch].
2562 * Rewrote parts of Silc Channel Payload interface in the
2563 lib/silccore/silcchannel.[ch]. The encode function now also
2564 encrypts the packet and parse function decrypts it.
2566 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Fixed a minor formatting bug in the SKE's key material processing.
2569 It actually might have processed the keys wrong way resulting
2572 * Redefined the mandatory HMAC algorithms and added new algorithms.
2573 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2574 and hmac-md5 truncated to 96 bits. The mandatory is now
2575 hmac-sha1-96. Rest are optional (including the one that used
2576 to be mandatory). Rationale for this is that the truncated HMAC
2577 length is sufficient from security point of view and can actually
2578 make the attack against the HMAC harder. Also, the truncated
2579 HMAC causes less overhead to the packets. See the RFC2104 for
2582 * Added new [hmac] configuration section. The SKE used to use
2583 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2584 is of course wrong. The official names that must be proposed in
2585 the SKE are the ones defined in the protocol specification
2586 (hmac-sha1-96 for example). The user can configure any hmac
2587 using any hash function configured in the [hash] section. At
2588 least, the mandatory must be configured.
2590 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2592 * Added HMAC list to the SKE proposal list. It has now both
2593 hash algorithm list and HMAC list. This makes the protocol
2594 incompatible with previous versions. The SKE now seems to work
2595 the way it is supposed to work, for the first time actually.
2597 * Defined plain Hash algorithms to the protocol specification.
2600 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Implemented support for key agreement packets into the server.
2603 Added functions silc_server_key_agreement and
2604 silc_server_send_key_agreement. Other than these functions,
2605 server has nothing to do with this packet.
2607 * Added support for private message key packets into the server.
2608 Added functions silc_server_private_message_key and
2609 silc_server_send_private_message_key.
2613 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2614 called in the protocol's final callback instead in the END
2615 protocol state. This makes a little more sense and in the same
2616 time in client we can use the same protocol routines for normal
2617 key exchange and to key agreement packet handling as well.
2619 * Added to both client's and server's KE protocol context the
2620 SilcSKEKeyMaterial pointer to save the key material. We will
2621 bring the key material to the protocol's final callback by doing
2622 this. The final callback must free the key material.
2624 * Added SKE's packet_send callback into client's KE protocol
2625 context so that the caller can choose what packet sending function
2626 is used. This way we can use different packet sending when
2627 doing normal SKE when doing key agreement packet handling (in
2628 the key agreement packet handling we do not want to encrypt
2631 * Implemented the responder side of the key agreement routines
2632 in the client. The client can now bind to specified port and
2633 accept incoming key negotiation. The key material is passed
2634 to the application after the protocol is over.
2636 * Implemented the processing of incoming Key Agreement packet
2637 in the client. Added function silc_client_key_agreement to
2640 * Implemented the intiator side of the key agreement routines
2641 in the client. The client can now initiate key agreement with
2642 another remote client. The key material is passed to the
2643 application after the protocol is over.
2645 * Created client_keyagr.c to include all the key agreement
2648 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2649 SILC_TASK_CALLBACK except that it is not static.
2651 * Created client_notify.c and moved the Notify packet handling
2652 from the client.[ch] into that file.
2654 * Created client_prvmsg.c and moved all private message and
2655 private message key routines from the client.[ch] into that file.
2657 * Create client_channel.c and moved all channel message and
2658 channel private key routines from the client.[ch] into that file.
2660 * Changed silc_client_get_client_by_id_resolve to resolve with
2661 WHOIS command instead of IDENTIFY command, in the file
2662 lib/silclient/idlist.c.
2664 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Implemented the SKE's responder side to the Client library.
2668 * When FAILURE is received to the protocol do not trust it
2669 blindly. Register a timeout to wait whether the remote closes
2670 the connection as it should do it, only after that process the
2671 actual failure. This was changed to both client and server.
2673 * Added client_internal.h to include some of the structures
2674 there instead of client.h in lib/silcclient/.
2676 * Added function silc_task_unregister_by_callback to unregister
2677 timeouts by the callback function.
2679 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Some "Incomplete WHOIS info" errors has been appearing on the
2682 log files. Took away the entry->userinfo check from WHOIS
2683 reply sending. The entry->userinfo is now " " if client did not
2684 provide one. I thought this was fixed earlier but something
2685 is wrong still. Let's see if the error still appears.
2687 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Fixed a minor bug in the login when the channel key is
2690 re-generated in the server. It used to generate the key in
2691 wrong order and thus caused problems in the channel traffic.
2693 * Fixed a minor bug in channel key distsribution after
2694 KICK command. The key was not sent to the router even though
2697 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added silc_ske_process_key_material_data as generic routine
2700 to process any key material as the SILC protocol dictates. The
2701 function is used by the actual SKE library but can be used by
2702 applications as well. This relates to the private message keys
2703 and the channel private keys since they must be processed the
2704 same way the normal SILC session keys. The protocol dictates
2705 this. Affected files: lib/silcske/silcske.[ch].
2707 Added also silc_ske_free_key_material to free the
2708 SilcSKEKeyMaterial structure.
2710 * Defined silc_cipher_set_key function to set the key for
2711 cipher without using the object's method function. The affected
2712 files: lib/silccrypt/silccipher.[ch].
2714 * Implemented silc silc_client_add_private_message_key,
2715 silc_client_add_private_message_key_ske,
2716 silc_client_del_private_message_key,
2717 silc_client_list_private_message_keys and
2718 silc_client_free_private_message_keys functions in the
2721 Added functions silc_client_send_private_message_key to send
2722 the Private Message Key payload and silc_client_private_message_key
2723 to handle incoming Private Message Key payload.
2725 * Added Cipher field to the Private Message Key payload to set
2726 the cipher to be used. If ignored, the default cipher defined
2727 in the SILC protocol (aes-256-cbc) is used.
2729 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Removed lib/silcclient/ops.h file.
2733 Redefined parts of the SILC Client Library API. Created new
2734 file silcapi.h that deprecates the ops.h file and defines the
2735 published Client Library API. Defined also private message key
2736 API and channel private key API into the file.
2738 This is the file that the application must include from the
2739 SILC Client Library. Other files need not be included by
2740 the application anymore.
2742 * Added new key_agreement client operation callback and also
2743 defined the Key Agreement library API for the application.
2745 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2748 is used by clients to request key negotiation between another
2749 client in the SILC network. If the negotiation is started it
2750 is performed using the SKE protocol. The result of the
2751 negotiation, the secret key material, can be used for example
2752 as private message key.
2754 Implemented the Key Agreement payload into the files
2755 lib/silccore/silauth.[ch].
2757 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Redefined ciphers for the SILC protocol. Added some new ciphers
2760 and defined the key lengths for the algorithms. Changed the
2761 code accordingly. The default key length is now 256 bits.
2763 * Fixed SKE key distribution function silc_ske_process_key_material
2764 when the key length is more than 128 bits. The default key
2765 length in SILC is now 256 bits.
2767 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2768 to indicate unsupported algorithm.
2770 * Renamed rijndael.c to aes.c and all functions as well.
2772 * Fixed a long standing channel key setting bug in client library.
2773 Weird that it has never surfaced before.
2775 * Fixed bug in channel deletion. If the entire channel is removed
2776 then it must also delete the references of the channel entry
2777 from the client's channel list as the client's channel entry and
2778 the channel's client entry share same memory.
2780 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Implemented CONNECT and SHUTDOWN commands in the client.
2784 * Implemented CLOSE command to the client.
2786 * Added the function silc_idlist_find_server_by_name into the
2787 files silcd/idlist.[ch].
2789 Added the function silc_idlist_find_server_by_conn into the
2790 files silcd/idlist.[ch].
2792 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * DIE command was renamed to SHUTDOWN. Updated the both code
2797 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2798 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2800 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2803 * Added function silc_server_create_connection function to create
2804 connection to remote router. My server implementation actually
2805 does not allow router to connect to normal server (it expects
2806 that normal server always initiates the connection to the router)
2807 so the CONNECT command is only good for connecting to another
2810 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2813 or some other client was kicked from the channel.
2815 Implemented the handling of the notify type to both client
2818 Implemented silc_server_send_notify_kicked to send the KICKED
2819 notify. It is used to send it to the server's primary router.
2821 * Implemented the KICK command into server and client.
2823 * Added `query' argument to the silc_idlist_get_client function
2824 to indicate whether to query the client from server or not if
2827 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2828 to indicate that the client is not channel founder.
2832 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Removed the rng context from SilcPacketContext structure and
2835 changed that the packet routine uses the Global RNG API.
2837 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Added support for quit message that client can "leave" on the
2840 channel when it quits the SILC. It is ditributed inside the
2841 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2843 Added silc_server_free_client_data that will take the
2844 signoff message as argument.
2846 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2848 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Updated parts of the protocol specification to keep it up
2853 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2856 payloads in one packet.
2858 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2859 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2860 use now the new List flag.
2862 * Also deprecated the following packet types: REPLACE_ID,
2863 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2865 * Added list support for Notify packet in server.
2867 * Added silc_server_send_notify_channel_change to send the
2868 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2869 the silc_server_send_replace_id.
2871 * Added silc_server_send_notify_nick_change to send the
2872 NICK_CHANGE notify type. Deprecates the function
2873 silc_server_send_replace_id.
2875 * Added silc_server_send_notify_join to send the JOIN notify type.
2876 Deprecates the function silc_server_send_new_channel_user.
2878 * Added silc_server_send_notify_leave to send LEAVE notify type.
2879 Deprecates the function silc_server_send_remove_channel_user.
2881 * Added silc_server_send_notify_cmode and
2882 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2883 types. Deprecates the silc_server_send_set_mode function.
2885 * Added SERVER_SIGNOFF notify type to indicate that server has
2886 quit. This means that all clients on the channel from that
2887 server will drop. This can be also used when netsplit happens.
2889 Deprecated REMOVE_ID packet type since it is not needed anymore
2892 Added silc_server_send_notify_server_signoff to send the
2893 SERVER_SIGNOFF notify type. Deprecates the function
2894 silc_server_send_remove_id.
2896 Added also silc_server_send_notify_signoff to send the
2897 SIGNOFF notify type.
2899 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2900 SILC protocol from this day on. Changed the protocol
2901 specification as well.
2903 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2904 notify type. It is used between routers to notify about
2905 topic changes on a channel.
2907 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2910 * Partly updated the protocol specification to comply with the
2911 changes now made. It is still though a bit outdated.
2913 * The JOIN notify type now takes one extra argument <Channel ID>.
2914 The packet used to be destined to the channel but now the
2915 JOIN type may be sent as list thus it is impossible to
2916 destine it to any specific channel. By adding this argument
2917 it is again possible.
2919 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added CREDITS file. The CHANGES and CREDITS file will appear
2922 in the distribution as well.
2924 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2927 types in the server's silcd/packet_receive.c.
2929 * Implemented CMODE and CUMODE to work in router environment.
2931 * Fixed minor encoding and decoding buglet from the
2932 lib/silccore/silcmode.c.
2934 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2937 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2939 * Changed all SilcConfigServer* and silc_config_server* to
2940 SilcServerConfig* and silc_server_config*, respectively.
2943 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Associated the ID (client or server ID) to the Authentication
2946 Payload to avoid any possibility of forging. Updated the
2947 protocol specification and the code accordingly.
2949 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * The RSA key length is now save to the RsaKey context in the
2952 key generation process in lib/silccrypt/rsa.c. The key length
2953 is now used to figure out the maximum size of the block allowed
2954 to be encrypted/signed.
2956 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2957 is equivalent to the silc_mp_mp2bin but does not allocate any
2960 * Changed silc_mp_mp2bin API to take length argument. If it is
2961 non-zero then the buffer is allocated that large. If zero, then
2962 the size is approximated using silc_mp_sizeinbase, which however
2965 * Created Global RNG API which is global RNG that application can
2966 initialize. After initializing, any routine anywhere in the
2967 code (including library) can use RNG without allocating a new
2968 RNG object. This was done to allow this sort of use of the
2969 RNG in code that has no chance to allocate RNG object. All
2970 applications currently allocate this and many routines in the
2971 library use this. Affected file lib/silccrypt/silcrng.[ch].
2973 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2974 it to use the Global RNG API.
2976 * Defined Authentication Payload into protocol specification that
2977 is used during SILC session to authenticate entities. It is
2978 used for example by client to authenticate itself to the server
2979 to obtain server operator privileges.
2981 Implemented this payload into the lib/silccore/silcauth.[ch].
2982 Implemented also routines for public key based authentication
2983 as the new protocol specification dictates.
2985 Moved definitions of different authentication methods from
2986 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2988 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2989 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2990 silc_pkcs_verify_with_hash functions into the file
2991 lib/silccrypt/silcpkcs.[ch].
2993 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * The client entry's userinfo pointer must be always valid.
2996 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2997 will fail since it requires the userinfo. Now, the userinfo
2998 is allocated as "" if actual userinfo does not exist. Actually,
2999 it must exist and it is totally Ok to drop client connections
3000 that does not announce the userinfo. However, we will make
3001 this workaround for now.
3003 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3004 to return the remote port by socket.
3006 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3009 SILC_SERVER_PENDING_EXEC and added an new macro
3010 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3011 data or when error occurs while processing the pending command.
3013 Added new argument `destructor' into silc_server_command_pending
3014 and to the SilcServerCommandPending object. This destructor is
3015 now called after calling the pending callback or if error occurs
3016 immediately. If error occurs the actual pending callback won't
3017 be called at all - only the destructor. The destructor may be
3018 NULL if destructor is not needed.
3020 All this applies for client library code as well. Similar
3021 changes were made there as well for the pending commands.
3023 In the client, the application must now allocate the
3024 SilcClientCommandContext with the silc_client_command_alloc
3027 * Added reference counter to the SilcServerCommandContext. Added
3028 function silc_server_command_alloc and silc_server_command_dup
3031 Same type of functions added to the client library for the same
3034 * Removed the cmd_ident from IDListData away since it is now
3035 global for all connections. It is the command identifier used
3036 in command sending and with pending commands. The affected file
3039 * Added reference counter to the SilcSocketConnection objecet to
3040 indicate the usage count of the object. The object won't be
3041 freed untill the reference counter hits zero. Currently only
3042 server uses this, and client ignores it. The client must be
3043 set to use this too later. The affected files are
3044 lib/silccore/silcsockconn.[ch]. Added also the function
3045 silc_socket_dup to increase the reference counter.
3047 This was mainly added because it is possible that the socket
3048 is removed underneath of pending command or other async
3049 operation. Now it won't be free'd and proper DISCONNECTING
3050 flags, etc. can be set to avoid sending data to connection that
3051 is not valid anymore.
3053 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3054 the connection. After that it sets SILC_SET_DISCONNECTED.
3055 It is, however, possible that the socket data is not still freed.
3056 The silc_server_packet_process now checks that data is not
3057 read or written to connection that is DISCONNECTED. The socket
3058 get's freed when the reference counter hits zero.
3060 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Changed the client operation API: channel_message operation's
3063 `sender' is now the client entry of the sender, not the nickname
3064 and the `channel' is the channel entry, not the channel name.
3066 In the private_message operation the `sender' is now also the
3067 client entry of the sender not the nickname.
3069 Affected file is lib/silcclient/ops.h and all applications
3070 using the client operations.
3072 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Moved the calling of ops->connect() from connect_to_server_final
3075 into receive_new_id functin since that is the point when the
3076 client is actually allowed to send traffic to network. The
3077 affected file is lib/silcclient/client.c.
3079 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3082 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3083 (if needs broadcasting) instead of broadcasting the packets one
3084 by one which would make a burst in the network traffic.
3086 * Added `broadcast' argument to the functions in silcd/server.[ch]
3087 silc_server_create_new_channel[_with_id] to indicate whether
3088 to send New Channel packet to primary router.
3090 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Added new function into the silcd/server.[ch] files:
3093 silc_server_create_new_channel_with_id to create new channel with
3094 already existing Channel ID.
3096 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3097 lib/silccore/silcpacket.h. This packet is used t send list of
3098 Set Mode payloads inside one packet. Server uses this to set
3099 the modes for the channels and clients on those channels, that it
3100 announced to the router when it connected to it. The protocol
3101 specification has been updated accordingly.
3103 * The silc_server_new_channel did not handle the packet coming
3104 from normal server as it normally does not send that. However,
3105 when it announces its channels it does send it. Implemented
3106 the support for that.
3108 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3109 into the file lib/silccore/id.h.
3111 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed memory leaks in the functions silc_idlist_del_client,
3114 silc_idlist_del_channel and silc_idlist_del_server in the file
3115 silcd/idlist.c. All of those leaked like a sieve.
3117 * Fixed some small memory leaks in the client's function
3118 silc_client_notify_by_server.
3120 * Added functions into silcd/server.c: silc_server_announce_clients,
3121 silc_server_announce_channels and silc_server_announce_server.
3122 These functions are used by normal and router server to announce
3123 to its primary router about clients, channels and servers (when
3124 router) that we own. This is done after we've connected to the
3127 These functions effectively implements the following packet types:
3128 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3129 and SILC_PACKET_NEW_ID_LIST.
3131 * Added new functions into the silcd/packet_receive.[ch]:
3132 silc_server_new_id_list, silc_server_new_channel_list and
3133 silc_server_new_channel_user_list to handle the incoming
3134 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3136 * Added support of changing Channel ID in the function
3137 silc_server_replace_id. If the server that announces a channel
3138 to the router already exists in the router (with same name but
3139 with different Channel ID), router is responsible to send
3140 Replace ID packet to the server and force the server to change
3141 the Channel ID to the one router has.
3143 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3144 client that the Channel ID has been changed by the router. The
3145 normal server sends this to the client. Client must start using
3146 the new Channel ID as the channel's ID.
3148 Implemented handling of this new type into lib/silcclient/client.c
3149 into the function silc_client_notify_by_server.
3151 * Added new function silc_idlist_replace_channel_id into the files
3152 silcd/idlist.[ch] to replace the Channel ID.
3154 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Call silc_server_command_identify_check always when processing
3157 the IDENTIFY command in silcd/command.c
3159 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3162 send keepalive packets. The packet can be sent by clients,
3163 servers and routers.
3165 Added function silc_socket_set_heartbeat into the file
3166 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3167 If not set, the heartbeat is not performed. The actual
3168 heartbeat is implemented in the low level socket connection
3169 library. However, application is responsible of actually
3172 Added silc_server_send_heartbeat to send the actual heartbeat
3173 packet into silcd/packet_send.[ch]. Server now performs
3174 keepalive with all connections.
3176 * Added silc_task_get_first function into lib/silcutil/silctask.c
3177 to return the timeout task with shortest timeout. There was a bug
3178 in task unregistration that caused problems. TODO has been
3179 updated to include that task system must be rewritten.
3181 * The client library will now resolve the client information when
3182 receiving JOIN notify from server for client that we know but
3183 have incomplete information.
3185 * Rewrote parts of silc_server_remove_from_channels and
3186 silc_server_remove_from_one_channel as they did not remove the
3187 channel in some circumstances even though they should've.
3189 * Encryption problem encountered in server:
3191 The LEAVE command used to send the Channel Key packet to the
3192 router immediately after generating it. However, the code
3193 had earlier sent Remove Channel user packet but not immediately,
3194 ie. it was put to queue. The order of packets in the router
3195 was that Channel Key packet was first and Remove Channel User
3196 packet was second, even though they were encrypted in the
3197 reverse order. For this reason, MAC check failed. Now, this
3198 is fixed by not sending the Channel Key packet immediately but
3199 putting it to queue. However, this is more fundamental problem:
3200 packets that are in queue should actually not be encrypted
3201 because packets that are sent immediately gets encrypted
3202 actually with wrong IV (and thus MAC check fails). So, packets
3203 that are in queue should be encrypted when they are sent to
3204 the wire and not when they put to the queue.
3206 However, the problem is that the current system has not been
3207 designed to work that way. Instead, the packet is encrypted
3208 as soon as possible and left to the queue. The queue is then
3209 just purged into wire. There won't be any fixes for this
3210 any time soon. So, the current semantic for packet sending
3213 o If you send packet to remote host and do not force the send
3214 (the packet will be in queue) then all subsequent packets to the
3215 same remote host must also be put to the queue. Only after the
3216 queue has been purged is it safe again to force the packet
3219 o If you send all packets immediately then it safe to send
3220 any of subsequent packets through the queue, however, after
3221 the first packet is put to queue then any subsequent packets
3222 must also be put to the queue.
3224 Follow these rules and everything works fine.
3226 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Added new function silc_server_remove_clients_by_server to
3229 remove all client entries from ID list when the server connection
3230 is lost. In this case it is also important to invalidate all
3231 client entires as they hold the invalid server entry. This
3232 fixes fatal bug when server has lost connection and will reconnect
3235 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Made some sanity checks to silc_server_daemonise like to check
3238 whether the requested user and group actually exists.
3240 * Added sanity check to SKE's silc_ske_responder_finish to check
3241 that the public and private key actually is valid.
3243 * Invalidate the client's nickname when receiving Replace ID
3244 packet and the Client ID is being replaced. This means that the
3245 server will query the nickname if someone needs it (client)
3248 * Sort the ID Cache in client library when the ID Cache data
3249 has changed (needs sorting).
3251 * Do not allow for SILC client to create several connections to
3252 several servers. The client does not support windows right now
3253 and generating multiple connections causes weird behaviour.
3255 Irssi-silc client does support windows and can handle several
3256 connections without problems, see: www.irssi.org and SILC plugin.
3258 * Fixed some places where client was added to the IDList. The
3259 rule of thumb is following (in order to get everything right):
3260 If the client is directly connected local client then the
3261 `connection' argument must be set and `router' argument must be
3262 NULL to silc_idlist_add_client function. If the client is not
3263 directly connected client then the `router' argument must
3264 bet set and the `connection' argument must be NULL to the
3265 silc_idlist_add_client function.
3267 * The funtion silc_server_packet_send_local_channel actually did
3268 not check whether the client was locally connected or not. It
3269 does that now. Fixed a bug related to LEAVE command.
3271 * Fixed Remove Channel User payload parsing bug in server's
3272 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3274 * The server's silc_server_save_channel_key now checks also the
3275 global ID list for the channel as it might not be in the local
3276 list. Fixed a bug related to LEAVE command.
3278 * Is this the end of the [<unknown>] buglet that has been lurking
3279 around for a long time? A little for loop fix in server's
3280 silc_server_command_whois_parse that is used by both IDENTIFY
3281 and WHOIS command. At least, this was a clear bug and a cause
3282 of one type of [<unknown>] buglet.
3284 * WHOIS and IDENTIFY commands call the function
3285 silc_server_command_[whois/identify]_check function even if
3286 we are not router server.
3288 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3290 * Added --with-gmp configuration option. If set the GMP
3291 is always compiled in the SILC source tree. If not set then
3292 it is checked whether the system has the GMP3 installed. If
3293 it has then the GMP won't be compiled (the system's headers
3294 and library is used), if it doesn't have it then the GMP is
3295 compiled in the SILC source tree.
3297 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Changed RSA private exponent generation to what PKCS #1
3300 suggests. We try to find the smallest possible d by doing
3301 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3302 not security fix but optimization.
3304 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added new config entry [Identity] to fork the server and run
3307 it as specific user and group. A patch from Bostik.
3309 * Imported Dotconf configuration library into lib/dotconf.
3310 This will be used to create the SILC configuration files later.
3311 It will appear in the distsribution after this commit.
3313 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * A big code auditing weekend happening. Auditing code for
3316 obvious mistakes, bugs and errors. Also, removing any code
3319 Removed files for being obsolete:
3321 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3322 inline in the file lib/silcutil/silcbuffer.h)
3324 o lib/silcutil/silcbufutil.c (the header has inline versions)
3326 Changed code to fix possible error conditions:
3328 o The buffer formatting routines now check that the destination
3329 buffer really has enough space to add the data. This applies for
3330 both buffer formatting and unformatting
3331 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3332 unformatting was changed to accomodate following rules:
3333 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3334 sent to the function while XXX_*STRING will not allocate or copy
3335 the data into the buffer. Instead it sets the pointer from the
3336 buffer into the pointer sent as argument (XXX_*STRING used to
3337 require that the pointer must be allocated already). This change
3338 makes this whole thing a bit more consistent and more optimized
3339 (note that the data returned in the unformatting with XXX_*STRING
3340 must not be freed now). The routines return now -1 on error.
3342 o Tried to find all code that use buffer_format and buffer_unformat
3343 and added return value checking to prevent formatting and
3344 especially unformatting errors and possible subsequent fatal
3347 o Changed ske->x and ske->KEY to mallocated pointers in
3348 lib/silcske/silcske.h. Fixed possible data and memory leak.
3350 o Added return value checking to all *_parse* functions. Fixed
3351 many memory leaks as well.
3353 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3354 so that buffer overflows would not happen. All code now also
3355 checks the return value as it can fail.
3357 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added reconnection support to server if the normal server looses
3360 its connection to the router (for example if router is rebooted).
3361 The server performs normal reconnection strategy implemented
3362 to the server. Affected file silcd/server.c.
3364 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3366 * Added new packet type SILC_PACKET_SET_MODE that is used to
3367 distribute the information about changed modes (for clients,
3368 channels and clients channel modes) to all routers in the
3369 network. Updated the protocol specification accordingly.
3371 Added functions into silcd/packet_send.c and
3372 silcd/packet_receive.c: silc_server_send_set_mode,
3373 silc_server_set_mode.
3375 Added new files silcmode.[ch] into lib/silccore that implements
3376 the encoding and decoding of Set Mode Payload. Added new type
3377 SilcSetModePayload. Moved the definitions of different modes
3378 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3380 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Oops, a little mistake in server's connection authentication
3383 protocol. The protocol is not ended with FAILURE but with
3384 SUCCESS if the authentication is Ok. :) Affected file is
3387 * Implemented NICK_CHANGE notify handling in server in the file
3388 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3389 the local clients on the channel. After the changing nickname
3390 in router environment snhould work and the [<unknown>] nickname
3391 should appear no more.
3393 The silc_server_replace_id function that receives the Replace ID
3394 payload now sends the NICK_CHANGE notify type also in the file
3395 silcd/packet_receive.c
3397 * Changed WHOIS and IDENTIFY command to support the maximum amount
3398 of arguments defined in protocol specs (3328 arguments). This
3399 fixed a bug that caused problems when there were more than three
3402 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Added extra parameter, command identifier, to the
3405 silc_client_send_command so that explicit command identifier
3408 Changed that ID list routines uses specific command identifier
3409 when sending WHOIS/IDENTIFY requests to the server so that they
3410 can be identified when the reply comes back.
3412 Affected files lib/silcclient/command.[ch],
3413 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3415 * Added `sender' argument to silc_server_packet_send_to_channel
3416 to indicaet the sender who originally sent the packet to us
3417 that we are now re-sending. Ignored if NULL. Affected file
3418 silcd/packet_send.[ch].
3420 * Added some server statistics support in silcd/server_internal.h
3421 SilcServerStatistics structure and around the server code. Also
3422 send some nice statistics information when client is connecting
3425 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Fixed channel ID decoding in server's JOIN command reply in
3428 silcd/command_reply.c
3430 * Fixed braodcasting of replace ID payload to not to send it if
3431 we are standalone server in silcd/packet_receive.c.
3433 * Fixed all channel message sending routines to not to send
3434 packets to clients that has router set, since they are routed
3435 separately in the same function earlier. Affects file
3436 silcd/packet_send.c and all channel packet sending functions.
3438 * In USERS reply, res_argv[i] are not allocated, the table
3439 is allocated. Thus changed that free the table, not its
3442 * In server's whois_check and identify_check if the client is
3443 locally connected do not send any WHOIS commands - they are not
3446 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Fixed some minor bugs in client when sending WHOIS command. The
3449 arguments was in wrong order.
3451 * Removed statis function add_to_channel from server in
3452 silcd/command.c that was previously used with the joining but
3455 * Tested USERS command in router environment successfully with two
3456 routers, two servers and two clients.
3458 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Reorganized the USERS command and command reply in client library
3461 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3462 When the command is given by user we register a pending command
3463 callback that will reprocess the command after the reply has been
3464 received from the server. When reprocessing the packet we then
3465 display the information. Thus, the USERS information is displayed
3466 now in the command callback instead of in the command reply
3467 callback. The processing of the command is same as previously
3468 when server has sent the command reply in the JOINing process.
3470 * Added to USERS command in silcd/command_reply.c to join the client,
3471 we didn't use to know about, to the channel after we've created
3472 a client entry for it. Also, for clienet we did know already still
3473 check whether it is on the channel or not and add it if not.
3475 * Removed silc_server_command_join_notify as the function and its
3478 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Changed the client's pending command handling to the same as the
3481 server's pending command handling. It is also now possible to
3482 execute command reply functions from other command reply
3483 function as the function callbacks for commands and command
3484 replies are one and same. The pending commands are not static
3485 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3486 in client connection context. Thus, pending commands are server
3487 connection specific as it is convenient.
3489 Changed the function silc_client_command_pending and
3490 silc_client_command_pending_del and added new function
3491 silc_client_command_pending_check. Removed the
3492 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3495 * Added cmd_ident, current command identifier, to the client
3496 connection context in lib/silcclient/client.h to keep track on
3497 command identifiers used in command sending. Client's command reply
3498 function handling now supports the mandatory command identifiers.
3500 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3501 funtions in client to fully support pending command callbacks.
3503 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3504 as one of the arguments to the application in the command reply
3507 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3508 before first releasing SILC but came back. Now it is removed again
3509 and should come back nomore. The FORWARDED flag was used only
3510 by the JOINing procedure by forwarding the command packet to router.
3511 Now, the JOINing procedure has been changed to more generic (due
3512 to various router environment issues) and FORWARDED is not needed
3513 anymore for anything. The protocol specification is yet to be
3516 Now, removed silc_server_packet_forward from server and the flag
3517 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3519 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Renamed NAMES command to USERS command. The NAMES was named that
3522 due to historical reasons. Now it is renamed. Also, rewrote
3523 parts of the USERS command. The nickname list is not sent anymore
3524 by the server. Only Client ID and mode lists are sent in the USERS
3525 command. Changed this also to the protocol specification.
3527 The client now resolves the names and stuff after it receives
3528 the USERS list from the server when joining to the channel.
3530 * WHOIS and IDENTIFY commands has been changed to support multiple
3531 Client ID's per command. One can now search for multiple users
3532 in the network by sending only one WHOIS or IDENTIFY command.
3533 Changed the code and the protocol specifications.
3535 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3536 uses silc_server_command_whois_parse to parse the request. */
3538 * If normal server, do not parse the WHOIS and IDENTIFY requests
3539 before sending it to the router. Saves some time.
3541 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Fixed JOIN command on client library. Wrong number of arguments
3544 used to crash the client.
3546 * Added silc_server_channel_has_global function to check whether
3547 channel has global users or not.
3549 * Added silc_server_channel_has_local function to check whether channel
3550 has locally connected clients on the channel.
3552 * The silc_server_remove_from_one_channel now checks whether the
3553 channel has global users or not after given client was removed from
3554 the channel. It also checks whether the channel has local clients
3555 on the channel anymore. If it does not have then the channel entry
3556 is removed as it is not needed anymore.
3558 * The silc_server_notify now checks on JOIN notify whether the joining
3559 client is one of locally connected or global. If it is global then
3560 the channel has now global users on the channel and that is marked
3561 to the channel entry. Also, it now saves the global client to
3562 global list who is joining and JOINs it to the channel. This is
3563 for normal server, that is.
3565 Changed silc_server_send_notify_on_channel,
3566 silc_server_packet_relay_to_channel and
3567 silc_server_packet_send_to_channel check if we are normal server
3568 and client has router set (ie. global client) do not send the
3569 message to that client, as it is already routed to our router.
3571 * Implemented LEAVE notify type handling in silc_server_notify
3574 * Tested LEAVE command in router environment successfully. Tested
3575 with two routers, two servers and two clients.
3579 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3581 * Implemented SIGNOFF notify type handling in silc_server_notify
3584 * silc_server_remove_id now removes the client entry from all channels
3585 it has joined and thusly sends SIGNOFF notify type.
3587 * Rewrote the NAMES list generation in server by removing two excess
3588 loops. The lists are created now inside one loop.
3590 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * silc_server_remove_channel_user checks now also global list
3593 for channel and client.
3595 * silc_server_new_channel_user checks now both local and global
3596 list for channel and client. Fixed a bug in client id decoding.
3597 Used to decode wrong buffer.
3599 * silc_server_channel_message checks now both local and global
3600 list for channel entry.
3602 * Tested channel joining (hence JOIN) in router environment
3603 successfully. Tested with two routers, two servers and two
3606 * Tested channel message sending in router environment successfully.
3608 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added silc_server_save_channel_key into server.[ch] to save the
3611 received channel key in Channel Key payload processing. It is
3612 also used in JOIN command reply handling.
3614 Equivalent function silc_client_save_channel_key added into
3615 client.[ch] into client library.
3617 * Changed JOIN command reply to send information whether the channel
3618 was created or not (is existing already) and the channel key
3619 payload. Changed protocol specs accordingly.
3621 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3622 the request was sent by ID and not by nickname. Crashed on
3625 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3627 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3628 now correctly save the received data.
3630 * silc_server_free_sock_user_data now notifies routers in the
3631 network about entities leaving the network.
3633 At the same time implemented functions silc_server_remove_id
3634 and silc_server_send_remove_id to receive and send REMOVE_ID
3635 packets. The packet is used to notify routers in the network
3636 about leaving entities. The ID removed will become invalid in
3639 * Added function silc_idlist_del_server into server. Removes and
3640 free's server entry from ID list.
3642 * silc_server_private_message function now checks, if we are router,
3643 that the destination ID really is valid ID, naturally.
3645 * In router when NEW_ID packet is received (for new client) the
3646 hash of the Client ID is saved in the ID Cache but the
3647 client->nickname is set to NULL, instead of putting the hash
3650 IDENTIFY command now also checks that client->nickname must be
3651 valid. If it is not if will request the data from the server who
3652 owns the client. Added new function
3653 silc_server_command_identify_check.
3655 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3656 to set the command to already allocated Command Payload.
3658 * Tested private message sending in router environment with two
3659 routers, two servers and two clients. Fixed minor bugs and now
3662 * Fixed segfault from client's NAMES command. Used to crash if
3665 * Forwarded packets must not be routed even if it is not destined
3666 to the receiver. Changed server code comply with this.
3668 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Added `require_reverse_mapping' boolean value to ServerParams
3671 structure. If TRUE (not default) the server will require that
3672 the connecting host has fully qualified domain name.
3674 If the reverse mapping is not required and hostname could not be
3675 found the IP address is used as hostname.
3677 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Implemented version string checking to both client and server.
3680 The check is incomplete currently due to the abnormal version
3681 strings used in development version of SILC.
3683 * Changed all command functions in server to use the new
3686 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Changed char *data to unsigned char *data in ID Cache system to
3689 support binary data as ID Cache data. Changed code to support
3690 binary data in lib/silccore/idcache.c.
3692 * Renamed silc_server_packet_relay_command_reply to
3693 silc_server_command_reply as it is normal packet receiving
3694 function. Rewrote the function to accept command replys for
3695 servers and not only for clients.
3697 * Mark remote router always as registered server if we are connecting
3698 to it. Otherwise, commands sent by the router to us are ignored.
3700 * All ID List find routines now returns the ID Cache Entry pointer
3701 as well if requested.
3703 * WHOIS command works now in router environment, tested with two
3704 routers, two servers and two clients.
3706 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3707 in router environment (as it is almost equivalent to WHOIS) but
3708 hasn't been tested thoroughly. Added new functions:
3710 silc_server_command_identify_parse
3711 silc_server_command_identify_send_reply
3712 silc_server_command_identify_from_client
3713 silc_server_command_identify_from_server
3715 * Disabled route cache adding because adding two different ID's with
3716 same IP replaces the old cache entry thus giving wrong route.
3717 The entry->router->connection is always the fastest route anyway
3718 so route cache may not be needed. Of course, new routes maybe
3719 established after receiving the ID when the entry->router->connection
3720 might not be anymore the most optimal.
3722 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Add route cache for received ID for fast routing.
3726 * Added silc_server_packet_route to route received packet on router
3727 that is not destined to us.
3729 * Renamed silc_server_get_route to silc_server_route_get.
3731 * Added id_string and id_string_len fields into SilcServer to
3732 include encoded ServerID for fast comparing without excess
3733 encoding of the ID's.
3735 * Cleaned up WHOIS command on server side. Added following static
3738 silc_server_command_whois_parse
3739 silc_server_command_whois_check
3740 silc_server_command_whois_send_reply
3741 silc_server_command_whois_from_client
3742 silc_server_command_whois_from_server
3744 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3745 arguments in command replies. All command functions should be
3746 updated to use this macro.
3748 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Minor typo fixes on command reply handling on server.
3752 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Added silc_server_command_add_to_channel internal routine to add
3755 the client to the channel after router has created the channel and
3756 sent command reply to the server.
3758 * Added generic silc_server_send_command to send any command from
3761 * Use static buffer with ID rendering instead of duplicating data.
3763 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Fixed a channel user mode bug when joining to a channel server gave
3766 everybody channel founder rights, oops.
3768 * We mark ourselves as the router of the incoming server connection
3769 if we are router ourselves. This way we can check in some packet
3770 sending functions whether it is locally connected server. For
3771 incoming router connections we put NULL.
3773 * For router sending packets locally means now always sending the
3774 packet cell wide; to local clients and local servers. For normal
3775 server sending packet locally means sending it to only local
3778 * Fixed the JOIN command to really work in router environment. If the
3779 channel is created it is always created by the router. Router is
3780 also responsible of making the initial joining to the channel,
3781 sending JOIN notify to the sending server and distributing
3782 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3783 does not exist server doesn't do anything else but forward the
3784 command to the router which performs everything.
3786 * Added silc_server_send_channel_key function to send the Channel Key
3789 * Added silc_server_create_channel_key to create new channel key. The
3790 channel key is now re-generated everytime someone joins or leaves
3791 a channel, as protocol dictates. Note: channel->key_len is the
3794 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3797 packet_receive.[ch] to separate packet sending and receiving
3798 routines. The server.[ch] now includes everything else including
3799 actual packet processing (writing and reading data) and other
3802 Renamed silc_server_private_message_send_internal to
3803 silc_server_send_private_message. The routine is still though
3804 used only to relay private messages as server does not send
3805 private messages itself.
3807 Renamed silc_server_new_channel to silc_server_create_new_channel
3808 and added new function sicl_server_new_channel that handles the
3809 incoming New Channel packet. Added also new sending function
3810 silc_server_send_new_channel to send New Channel Payload.
3812 * Added new function silc_server_notify to process incoming notify
3813 packet to the server/router. Server may then relay the notify
3814 to clients if needed.
3816 * Added new function silc_server_new_channel_user to process incoming
3817 New Channel User packet. Router will redistribute the packet and
3818 send JOIN notify to its local clients and locally connected servers
3819 if needed. Normal server will send JOIN notify to its local client
3820 on same channel when received this packet. Added also corresponding
3821 sending function silc_server_send_new_channel_user to sent the
3824 * Added boolean route argument to send_notif_to_channel and
3825 packet_send_to_channel functions to attempt to route the packet
3826 if it is TRUE and send only locally if it is FALSE.
3828 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * silc_server_replace_id now broadcasts the received replace ID
3831 packet if it is not broadcast packet already. The router must
3832 broadcast to inform other routers about changed ID.
3834 * Added backpointer to server's router into SilcServer context in
3835 silcd/server_internal.h.
3837 * Fixed silc_server_packet_broadcast to send correct broadcast
3840 * The channel key is now distributed to the local client as soon
3841 as it is received from the router (in router environment) so that
3842 no other packet may be sent for the channel until client has
3845 * silc_server_remove_channel_user now broadcasts the received
3846 Remove Channel User packet if it is not broadcast packet already.
3847 The router must broadcast to inform other routers about removed
3850 * Added users field into SilcPacketContext that is a reference count
3851 of the context. One can increase the reference count by calling
3852 silc_packet_context_dup which is now changed to just increase the
3853 reference count instead of duplicating the data. The reference
3854 count is decresed by calling silc_packet_context_free that will
3855 free the data after the reference count hits zero.
3857 For now on the packet context and everything allocated into it
3858 (including the raw packet from network) must be freed by calling
3859 the new silc_packet_context_free function. Added also new function
3860 silc_packet_context_alloc that must be used now to allocate the
3861 context. This also means that if a routine is asynchronous from
3862 silc_[client/server]_packet_parse_type the packet context must
3863 be duplicated by calling silc_packet_context_dup. Otherwise it
3864 gets free'd after silc_[client/server]_packet_parse_type returns.
3865 Also, one must remember that if packet is duplicated then its
3866 reference count must be decresed by calling the free function as
3867 many times as it was duplicated.
3869 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3870 from both client and server.
3872 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Made joining to a channel working in router environment.
3876 * Cleaned up JOIN command on server side and create function
3877 silc_server_command_join_channel internal routine to make the
3880 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Changed silc_command_pending list to SilcDList. Also, added
3883 `ident' field to SilcServerCommandPending structure to identify
3884 the reply and to call correct callback.
3886 Added silc_server_command_pending_check function to replace the
3887 corresnponding macro. The silc_command_pending list is not
3890 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3891 to set identifier to previously allocated Command Payload. It
3892 is used to set identifier for command when resending Command
3895 * Added silc_command_payload_encode_payload to encode Command
3896 Payload buffer from SilcCommandPayload structure.
3898 * Added silc_argument_payload_encode_payload to encode Argument
3899 payload buffer from SilcArgumentPayload structure.
3901 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Changed WHOIS command to support router connection on server side.
3904 The whois request is always sent to router unless the server is
3905 standalone server. After server has received the reply from the
3906 router will it send the reply to the client.
3908 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3909 broadcast received broadcast packet. The function is used only
3910 by router. The broadcast packet is always sent to the router's
3913 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3914 render given ID to printable string, for log files for example.
3916 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Made basic router to router connections working. At least they
3919 can now connect to each other but nothing really works the way
3920 they are supposed - yet.
3922 * Added new initiator token to RouterConnection configuration
3923 file in silcd/serverconfig.[ch]. It is used to tell whether we
3924 are the initiator to the remote router or whether we'll expect
3925 the other end to connect.
3927 * Moved registering of listener task to silc_server_init, hence
3928 the server starts listenning as soon as it is run, even if it
3929 does not have connections to other routers. Let's see how well
3932 * Changed default connection retry timeouts for more suitable in
3935 * Removed cipher and such arguments from silc_idlist_add_client
3936 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3937 Added new function silc_idlist_add_data to add the keys and stuff
3940 * Added SilcIDListData structure and added it to SilcClientEntry
3941 and SilcServerEntry as their first field in the structure. This
3942 way we can explicitly cast the ID entries to the SilcIDListData
3943 structure and get common data for the entries. In past, we had
3944 to first check what type of connection it is and then cast it to
3945 correct ID entry type. Now, we can directly cast the opaque
3946 pointer to the SilcIDListData (no matter what ID entry it actually
3947 is) and get the data needed.
3949 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3952 in some circumstances even if threre were timeout tasks, though not
3953 IO tasks, but tasks anyway. Now fixed.
3955 * Defined SilcServerConnection structure to hold connection specific
3956 stuff about directly connected servers and routers. The definition
3957 is currently in silcd/server_internal.h. I thought about having
3958 a bit more important role fro this struct but for now it is used
3959 only when connecting to other server (or router actually).
3961 * Added connecting retry support in server when connecting to
3962 router(s). The retry feature implement exponential backoff
3963 algorithm. Also, added SilcServerParams structure to hold default
3964 parameters for server. For now, it include these retry settings
3965 and are hard coded. After server is moded to be as Silc Server
3966 Library this structure will be more important.
3968 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Changed client librarys channel->clients table to SilcList and
3971 changed code accordingly.
3973 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Changed client's channel table to SilcList and changed code
3976 accordingly. Also changed SilcChannelClientEntry to include back-
3977 pointer to the channel so that client entry can use that structure
3978 as list as well and we have fast cross-reference to the channel.
3979 This change dramatically decreased the complexity of channel
3980 handling with client entry and vice versa (removed one extra
3981 loop when searching for channel entry from many functions).
3983 * Changed server->sim from table to SilcDList and changed code
3986 * NAMES command can now be used from user interface. It will show
3987 the user list on the channel, neatly.
3989 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3990 Code now saves realname of the user if it becomes available.
3992 * Renamed configure.in to configure.in.pre and made ./prepare
3993 script to automatically add correct version string to
3994 configure.in which it creates from configure.in.pre.
3996 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * NAMES command reply now shows users mode with the nickname when
4001 * Moved silc_client_ch[u]mode[_char] functions from
4002 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4003 place sucks, they are utility functions and should be in some
4006 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4008 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4011 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Added TRQ (efficient deque and list library) into lib/trq. This is
4016 a very good list library that is currently used in the SILC. Defined
4017 SilcList API over the library because I didn't like the API very
4018 much. See lib/trq/silclist.h for the API and examples of how to
4019 use the API. Fixed various places in the code to use the new
4020 SilcList API. The SilcList is meant for lists that has a structure
4021 already defined as a list. It is not suitable to add just some
4022 context to the list (in TRQ, the context is the list actually).
4024 So, I defined SilcDList that can be used for the purpose where
4025 predefined list structure does not exit. This can be used as
4026 such list. Now some context just can be added to the SilcDList.
4027 Currently this list is not used in the SILC just yet, though there
4028 are a lot places where this can replace dynamically allocated
4029 tables and I will fix these places, later, to use SilcDList.
4030 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4031 and use TRQ internally).
4033 Also fixed some annoying warning messages that the original TRQ
4034 code generated. Also minor changes to TRQ's Makefile.in.
4036 * Added support for querying by Client ID to both WHOIS and
4037 IDENTIFY commands into server, as required by the protocol.
4039 * Removed method function pointers from SilcBuffer structure. They
4040 weren't used to anything and just increased the context size for
4041 no good reason. This change also made silc_buffer_alloc and
4042 silc_buffer_free functions inline functions.
4044 * Disabled command flooding detection support until it's fixed so
4045 that it accepts commands in but does not execute them more than once
4048 * Added silc_net_localhost(), to return local hostname, into
4049 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4050 that must be initialized before calling silc_client_init.
4052 * Added new function: silc_server_send_notify_on_channels to send
4053 notify messages to all channels client has joined. It is assured
4054 that the message is sent only once per client.
4056 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4057 lib/silcutil/silcutil.[ch] as silc_format function. The new
4058 function is generic and is used by server as well, not only by
4059 the logging routines.
4061 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4062 the provided version string was not acceptable. Added new function:
4063 silc_ske_check_version into lib/silcske/silcske.h. The function
4064 must be implemented by the application (client or server) and it
4065 does not reside in the SKE library. The function checks the version
4066 string remote end sent.
4068 * Added back pointers (to opaque context and to SilcSocketConnection)
4069 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4071 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4072 duplicate packet context structure.
4074 * Changed `notify' client operation to send same arguments as client
4075 receives from server except for ID's. ID's are mapped to correct
4076 ID entry and that is returned. Also, if channel entry is not sent
4077 by server but the notify is for channel the channel entry is sent
4078 to application (otherwise application doesn't know that it is for
4079 channel (library gets it from packet's Destination ID)).
4081 * Added silc_client_remove_from_channels into client library to
4082 remove a client from all channels it has joined to. Used when
4083 received SIGNOFF notify from server. Added also new function
4084 silc_client_replace_from_channels to replace old ID entry with
4085 new ID entry on all channels. Used when received NICK_CHANGE
4088 * Fixed ID Cache list handling in silc_idlist_get_client in
4089 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4090 to get (or query) client by ID.
4092 * Updated TODO list.
4094 * Added connection authentication status message defined by the
4095 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4096 support for these into the code in client and server side.
4098 * Added generic function silc_client_send_command to send any command
4099 with variable argument list. Application should use this function
4100 to send commands if the command functions provided by the library
4101 does not suite for the application's user interface needs.
4103 * Added new `failure' client operation. Application is notified about
4104 received failure packet if client is executing a protocol. In this
4105 case the protocol's execution has failed.
4107 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4108 is required by the protocol.
4110 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4111 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4114 * Added status flag to SilcSKE object to indicate realtime status
4115 of the SKE protocol.
4117 * Application receives now exactly same command reply arguments as
4118 the library receives from server. However, if ID is received the
4119 corresponding ID entry is returned to the application (eg. Client
4120 ID is mapped to correct SilcClientEntry entry and that is returned).
4121 Changed command_reply client operation due to this change.
4123 * Changed all ID's in commands and in command replys as ID Payloads.
4124 Change affected both client and server side codes.
4126 All ID's sent in SILC network (with execption of ID's in SILC
4127 Packet header) are sent in ID Payload to support variable length
4130 * Server now notifies nick changes and notifies all clients on
4131 the channels about the new nickname (about the new Client ID,
4134 * Implemented CMODE command to change channel modes. Supports all
4135 channel modes defined by the protocol specs except ban and invite
4136 lists. (Also, private channel key mode is supported but support for
4137 setting private channel key in client is missing, thus, this mode
4138 has no effect on client side (except that server requires that the
4139 client uses private channel key and normal channel traffic does not
4142 Also, invite mode works per se, but INVITE command does not work
4143 yet correctly, so you can set channel as invite only channel but
4144 inviting clients to the channel does not work (it is yet to be
4145 thought what's the best way to do it).
4147 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4148 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4149 Implemented CUMODE command to change user's mode on the channel.
4150 Supports all modes defined by the protocol specs.
4152 * Added NAMES command reply to return users modes on the channel.
4154 * Removed unnecessary and slow ciphers from lib/silccrypt.
4156 * Set SO_KEEPALIVE option to connection sockets by default.
4158 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4160 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4161 redefined the Notify Payload into protocol specs.
4163 * Added silc_id_payload_parse_id to get ID directly from raw
4166 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4169 accept searching by Client ID as well.
4171 * Added support for LEAVE and SIGNOFF notify types in client library.
4173 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4174 to parse ID Payload from raw data.
4176 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Added flags parameter into silc_ske_assemble_security_properties
4179 function in lib/silcske/silcske.[ch].
4181 * Changed notify client operation to fit better for notify messages
4182 sent by server. The notify payload received from server is now
4183 passed to the application (after parsing it to SilcNotifyPayload).
4184 It is application's responsibility to retrieve the arguments
4185 from the payload and show the message the way it wants. The message
4186 sent by server is implementation specific.
4188 * Changed public keys to comply with the protocol specification.
4189 Old public keys are not supported anymore and are not compatible.
4191 * Removed nickname from Channel Payload as the latest draft removed
4192 it. The client must resolve the nickname from the NAMES command
4193 reply received when it joined the channel.
4195 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4197 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Fixed some errors in protocol specification drafts.
4201 * Created lib/silccore/silcnotify.c to implement Notify Payload
4202 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4203 generic payloads described by protocol specifications. The file
4204 includes implementations for ID Payload and Argument Payload.
4206 * Changed Command Payload implementation to use the new Argument
4207 Payload. Changed command_xxxx_payload to command_payload_xxxx
4208 to comply with SILC coding conventions.
4210 * Added suppport for Argument Payload handling in Notify Payload
4211 implementation as protocol requires it. Added the new support
4212 into server and client lib as well.
4214 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Added support for multiple nicknames on same channel. [n] is
4217 added locally to the nickname if there are more than one same
4218 nicknames on the channel.
4220 * Server now sends all nicknames that matched WHOIS request.
4221 Client also shows the list received from server.
4223 * Added TOPIC command to client side. User can now set and show
4224 current topic on channel.
4226 * Added MOTD command to client and server. Also, server sends the
4227 motd when client connects to the server.
4229 * Changed version strings to comply ISO 8601.
4231 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Fixed protocol error handling in client library. It should now
4234 cope even if the SKE fails for some reason.
4236 * Made new protocol specification drafts for submitting to IETF.
4238 * Implemented TOPIC command to server in silcd/command.c.
4240 * Added two new notify types into lib/silccore/silcnotify.h:
4241 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4242 notify nickname change and topic setting/change on a channel.
4244 * API change of command_reply operation in client library. The
4245 application gets now the status type received from server as well.
4247 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4251 * Cras fixed and optimized the packet handling even further and
4252 it should work now. Minor change to the prototype of function
4253 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4255 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Added new function into lib/silcutil/silcschedule.[ch]:
4258 silc_schedule_with_fd to select() a specified fd. The function
4259 returns after timeout expires or data arrives or goes. The
4260 function is used by packet routines to wait that all data is
4261 received from network.
4263 * Fixed data reading from network in lib/silccore/silcpacket.c.
4264 The code now assures that all data is read from the fd and then
4265 continues packet processing. This was a bug fix since the code
4266 used to drop some data in some circumstances.
4268 * Added new function into lib/silcclient/client.[ch]:
4269 silc_client_start_key_exchange to start key exchange after
4270 connection has been established to server. The code internally
4271 now uses this funtion but its main purpose was to provide it
4272 for applications that perform their own connecting. After
4273 application has created a connection it merely calls this
4274 function to start the key exchange between client and server.
4275 The library takes care of everything else after that.
4277 Updated also lib/silcclient/README to explain the usage of
4280 * Do not send to application information that connection has
4281 been established. Application gets notified it by connect
4284 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Applied cras's patch to add silc_schedule_one function. The
4287 function runs scheduler once and returns.
4289 * Fixed the scheduler after cras messed it up. The timeout
4290 handling works now as it's supposed to work.
4292 * Added into lib/silccore/ silcnotify.h to include notify
4293 message types support. Changed silc_server_send_notify*
4294 functions, in server.[ch], to support those new notify types.
4295 Added the support for the notify types into client library,
4296 as well. Added new notify client operation into ops.h in
4299 * Changed silc_server_packet_send_to_channel to send normal
4300 packets instead of just channel message packets. The function
4301 is now used to send the notify packets to channels. It is not
4302 used to send channel message packets anymore, as server never
4305 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4306 va_arg()s as it seems to require it nowadays. I guess, if SILC
4307 is compiled with older va_arg() the new code should work anyway.
4309 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Splitted core library. Core library (lib/silccore) includes
4312 now only SILC protocol specific core (and common) components.
4313 Created new utility library (lib/silcutil) that includes more
4314 generic purpose stuff. The stuff for util library was taken
4315 from the old core library. This was minor and easy split.
4317 * Created SILC Client Library (lib/silcclient) that includes
4318 implementation of the SILC client without user interface. This
4319 was major move from silc/ directory. The code has been changed
4320 so that it is transparent towards the user interface. The
4321 silc/ directory includes now the same user interface as before
4322 and it uses the new client library. Read lib/silcclient/README.
4323 Basicly, the client library performs everything else related
4324 to SILC except user interface handling. Also, configuration
4325 files are considered to be part of user interface and library
4326 does not handle them.
4328 This change also changed a lot of structures, function naming etc.
4329 Most important change was that SilcClientWindow object was
4330 renamed to SilcClientConnection in the client library. Created
4331 also new file lib/silcclient/ops.h. Also added new files
4332 silc/local_command.[ch] and silc/client_ops.[ch].
4334 All these changes were made to make it easier for user interface
4335 designers to create what ever user interface for the SILC client
4338 It is also expected that the server will be moved to lib
4339 directory as well and SILC Server Library will be created;
4340 sometimes in the future.
4342 * Removed Local commands from lib/silccore/silccommand.h as
4343 they are application specific and new client library does not
4344 handle any of those anymore.
4346 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4347 old client implementation in silc/.
4349 * Added support for callback functions in SILC_LOG_* macros.
4350 Application can now set its own callbacks that will be called
4351 instead of using the default functions that will always print
4352 the debug messages to stderr (or stdout). Also, debugging can
4353 now be disabled by setting silc_debug to FALSE and re-enabled by
4354 setting it to TRUE. Note, that logging will still work even
4355 if debugging is disabled.
4357 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4358 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4359 silc_log_reset_debug_callbacks.
4361 * To enable debugging in silc client one must give now -d
4362 option on command line.
4364 * Changed silc_schedule_init to automatically allocate task queues
4365 if they are not allocated before calling it.
4367 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Added GMP 3.1 into math library.
4371 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4374 a channel in SILC network. The packet is used by servers and
4375 routers to notify other routers that user has left a channel.
4376 This little feature was missing until now. Added the feature
4377 to protocol specification as well.
4379 Added functions: silc_server_send_remove_channel_user and
4380 silc_server_remove_channel_user into server.[ch].
4382 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4383 lib/silccore/silcpacket.h. However, they are not implemented
4386 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Fixed joining to a channel and sending channel messages
4389 between server and router. The channel message sending should
4390 now work inside a cell.
4392 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Fixed the private message sending between server and router.
4395 The private message sending should now work inside a cell.
4397 * Added silc_server_replace_id into server.[ch] to replace
4398 existing ID in the SILC network.
4400 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4401 and silc_idlist_replace_server_id into idlist.[ch] in server.
4403 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Fixed the server to server connections. Server can again now
4406 connect to router. Router to router connections probably does
4409 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Added dynamic protocol registering support. Now protocols can
4412 registered and unregistered on the fly. Patch by cras.
4414 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added lib/contrib directory to hold routines that some platforms
4417 don't have but are needed by SILC.
4419 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4420 into lin/contrib to provide getopt() and getopt_long() for
4421 those who don't have it.
4423 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Added AWAY command to client. When away message is set and
4426 client receives a private message packet the client automatically
4427 replies to the sender with the away message.
4429 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4430 bug seemed to be the cause of recent problems when compiling
4433 * Added version detection support to SKE protocol specification
4434 and added the new changes to the SKE implementation as well.
4435 There were other minor changes in the SKE protocol as well.
4437 Many changes in lib/silcske/silcske.[ch] and in
4438 lib/silcske/payload.[ch].
4440 * Added ^U functionality, clear input line. Patch from cras.
4442 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Mainly small bugfixes on core library. Fixed some debugging
4445 logging and buffer overflow in silclog.c.
4447 * Updated config.sub and config.guess on the distribution tree.
4449 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added command lagging support in server. Client may execute
4452 commands now only once in two seconds.
4454 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Optimized packet reception. MAC computation and checking is now
4457 also more optimized. A lot previously duplicated code is now
4458 used as generic by both client and server.
4460 * Fixed key pair generation in clientutil.c
4462 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added into lib/silccore/silcbufutil.[ch] new function;
4465 silc_buffer_realloc.
4467 * Moved generic packet sending/encryption functions to
4468 lib/silccore/silcpacket.[ch] from client and server. Some
4469 rewriting of the functions.
4471 * Moved all generic packet reception/decryption functions to
4472 lib/silccore/silcpacket.[ch] from client and server. The
4473 packet processing is now much cleaner in both client and server.
4474 These were major changes in both client and server.
4476 * Created many common functions in server to do packet sending.
4477 Previously code were duplicated a lot, this has been removed
4480 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Rewrote major parts of the ID cache system. Don't know
4483 whether it is better now or not but at least the API is more
4486 * Major rewrite on ID cache stuff on client because of the ID
4487 cache API changes. Added idlist.c to client.
4489 * Also major rewrite on ID cache stuff on server as well.
4490 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4491 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4492 in hand, instead they are all put into the ID cache system now.
4493 All server_idlist_* routines uses ID cache now instead of
4494 traversing its own lists (those lists does not exist anymore).
4495 SilcIDList though still exists. Also, SilcXXXEntry's are
4498 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Finally made the SKE implementation compliant to the protocol
4501 specification. All mp integers are now binary encoded as
4502 opposed being HEX encoded.
4504 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4507 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4508 functions: silc_[encode/decode]_pem. Also added function
4509 silc_encode_pem_file to PEM encode with newlines ('\n') for
4512 * SILC public keys are now encoded either PEM or binary. Same
4513 option is for private keys as well. By default private keys
4514 are binary encoded and public keys PEM encoded. Silly HEX
4515 encoding were removed.
4517 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4518 function to create fingerprints.
4520 * Fixed a bug in SHA1; does not change the original data anymore.
4522 * Partly implemented INFO command on client and server side.
4523 Fixed CLEAR command. Changes to SERVER command; show current
4524 server(s) when giving command without arguments. Added
4525 VERSION command to client.
4527 * Added check to server that unregistered connections cannot
4528 execute commands (unless it is specificly allowed).
4530 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Fixed screen refresh.
4534 * Fixed channel joining bug from client. On some circumstances
4535 client tried to join to a channel it had already joined.
4537 * Added public key verification process into client's protocol.c.
4538 The client now verifies the public key from user and saves
4539 it into ~./silc/serverkeys/ directory.
4541 Added into: clientutil.[ch]: silc_client_verify_server_key.
4543 * Changed SKE protocol's silc_ske_initiator_finish function
4544 to accept callback function that verifies the received public
4545 key. Removed old silc_ske_verify_public_key function.
4547 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4550 silc_pkcs_private_key[_data]_set.
4552 * Made the password and public authentication more cleaner in
4553 server's protocol.c.
4555 * Removed historic and obsolete protocol `channel_auth' from
4556 both client and server.
4558 * Removed wrong way of sending command status messages from
4559 server to client in server's command.c. The old way violated
4560 protocol specification.
4562 Changes to silccore/silccommand.[ch]: removed
4563 silc_command_encode_status_payload -> not needed anymore,
4564 changed silc_command_encode_payload_va to accept extra
4565 argument on variable argument list. The argument type must
4566 now be provided to the function. Also, added new function:
4567 silc_command_encode_reply_payload_va which is same as
4568 normal command_encode_payload_va except command status type
4569 is provided as extra argument.
4571 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Added ~./silc directory handling. The directory includes the
4574 public and private keys for the client.
4576 Added silc_client_check_silc_dir, silc_client_create_identifier
4577 and silc_client_load_keys.
4579 * Implemented SILC protocol compliant public key. Added public
4580 and private key saving to and loading from files.
4582 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4583 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4584 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4585 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4586 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4588 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4589 silc_pkcs_load_[public/private]_key.
4591 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Added silc_server_get_route (route.[ch]) to get connection
4594 data for the fastest route for given ID.
4596 * Implemented INVITE command on client and server. The command
4597 were re-defined in the SILC Protocol Specification and the
4598 implementation now complies with the specification.
4600 * Implemented PING command on client and server.
4602 * Implemented NAMES command on client and server. The server side
4603 supports currently only normal server not router server yet.
4604 Some changes to NAMES definition in SILC protocol specification.
4606 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Implemented LEAVE command on client and server.
4610 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4611 again. This change was made to the protocol as well. Server
4612 should not violate the protocol specification anymore.
4614 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4617 was tested. SOCKS4 was not but should work anyway.
