3 * Fixed a double free in disconnection in the server. Affected
4 file is silcd/server.c.
6 * Fixed the lib/silcske/groups.c to work now also with GMP
7 MP library. The string conversion did not work when using
8 specific base and the base is indicated in the string as well.
10 * Created win32/ directory which now includes MSVC++ specific
11 stuff so that toolkit (DLLs) may be compiled with MSVC++.
12 It will appear only in the toolkit distribution
14 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Changed the key material distribution function in case when
17 the hash output is too short. The data is now concatenated
18 a bit differently than it used to. Made the change to the
19 SKE protocol specification.
21 * Added better GMP detection to configure.in.pre. A patch
24 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
26 * Fixed a minor bug in SKE that might cause some problem on
27 some platforms. Affected file lib/silcske/silcske.c.
29 * Added the cookie checking for initiator in the SKE. It checks
30 that the responder returns the sent cookie unmodified. The
31 affected file is lib/silcske/silcske.c. Added new SKE
32 error type INVALID_COOKIE that can be sent during the
33 negotiation. Fixed some memory leaks as well.
35 * Added the "invalid cookie" error message to Irssi SILC client's
38 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
40 * Added `task_max' field to the SilcClientParams to indicate
41 the maximum tasks the scheduler can handle. If set to zero,
42 default values are used. Affected file lib/silcclient/silcapi.h.
44 * Fixed memory leaks in silc_client_close_connection. Affected
45 file lib/silcclient/client.c.
47 * Added silc_client_del_client_entry to client library to free
48 all memory of given client entry. Affected file is
49 lib/silcclient/idlist.[ch].
51 * Added new functions silc_client_del_channel and
52 silc_client_del_server to delete channel and server entries.
53 Affected file lib/silcclient/[silcapi.h/idlist.c].
55 * Removed silc_client_del_client_by_id from silcapi.h.
57 * Fixed the INFO command to return the server's own info
58 correctly when querying by Server ID. Affected file is
61 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
63 * Removed the non-blocking settings in WIN32 code in the
64 silc_sock_[read/write] and added SleepEx instead. Affected
65 file lib/silcutil/win32/silcwin32sockconn.c. The availability
66 of input data is now checked with FIONREAD and ioctlsocket.
68 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
70 * Call silc_schedule_task_del_by_context in the
71 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
72 Affected file lib/silccore/silcprotocol.c.
74 * Call silc_protocol_cancel for active protocols in the
75 silc_server_close_connection if the funtion
76 silc_server_free_sock_user_data has not been called.
77 Affected file silcd/server.c.
79 * Generic tasks cannot be deleted using the del_by_fd
80 task deleting function since generic tasks does not match
81 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
83 * Added a notion to SILCOPER help file that the SILCOPER works
84 only on router server, not on normal server.
86 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
88 * Added for WIN32 support for the new scheduler as well.
89 Affected file lib/silcutil/win32/silcwin32schedule.c.
91 * Fixed the SHA1 implementation to work on various platforms.
93 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
96 API. It is part of the scheduler now. Everything else is
97 as previously but some functions has changed their names.
98 Checkout the lib/silcutil/silcschedule.h for the interface.
99 Updated all applications to use the new interface. Affected
100 files are lib/silcutil/silcschedule.[ch].
102 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
104 * Found a bug in the SKE implementation. The HASH value,
105 specified by the protocol, was not computed correctly. The
106 public key of the responder was not added to the computation
107 even though it is mandatory. Affected file lib/silcske/silcske.c.
108 This unfortunately causes incompatibilities with older
111 * Added WIN32 specific network init and uninit functions:
112 silc_net_win32_init and silc_net_win32_uninit to init and uninit
113 the Winsock2. Affected file lib/silcutil/silcnet.h and
114 lib/silcutil/win32/silcwin32net.c.
116 * Set the socket always to nonblocking mode on WIN32 after
117 reading data or writing data. Affected file is
118 lib/silcutil/win32/silcwin32sockconn.c.
120 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
122 * Fixed various compilation problems under WIN32. Affected
123 files lib/silcutil/win32/silcwin32thread.c and
124 lib/silcutil/win32/silcwin32schedule.c.
126 * Removed all _internal.h #includes from public header
127 files. Internal headers must never be included from
130 Removed also the lib/silcske/payload_internal.h file.
132 * All include files that may be needed (public and some others
133 included by the public headers) by application developers are
134 now copied to the ./includes directory. It does not copy any
135 internal headers. Affected file Makefile.defines.pre and all
136 Makefile.am's under lib/ and subdirs.
138 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
140 * Do not change the ~/.silc directory's permissions automatically.
141 Affected file irssi/src/silc/core/clientutil.c.
143 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
145 * Do not cancel the protocol in silc_server_close_connection
146 it might cause recursion. Now cancelled in the function
147 silc_server_free_sock_user_data. Affected file silcd/server.c.
149 * Fixed the silc_server_remove_clients_by_server to regenerate
150 the channel keys correctly finally. Added also new function
151 silc_server_remove_clients_channels to actually do it.
152 Affected file silcd/server.c.
154 * Fixed the silc_server_new_channel to not crash by giving
155 wrong router to the new channel. Affected file is
156 silcd/packet_receive.c.
158 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
160 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
161 which is given as argument to the silc_client_alloc now.
162 It can be used to configure the client and set various parameters
163 that affect the function of the client.
165 * The USERS command in server did not check whether the channel
166 is private or secret. Affected file silcd/command.c.
168 * Added new argument to the USERS command in protocol specification.
169 The USERS command now can take the channel name as argument
170 as well. Added support for this in client and server and
171 updated the protocol specs.
173 * Completed the GETKEY command in client. It can be now used
174 to fetch also servers public key not only some clients.
175 Affected files lib/silcclient/command[_reply].c.
177 * Added silc_client_get_server to return server entry by the
178 server name. Affected files lib/silcclient/silcapi.h and
181 * Redefined the IDENTIFY command in protocol specification to be
182 more generic. It now can be used to query information about
183 any entity in the SILC Network, including clients, servers and
184 channels. The query may be based either the entity's name
185 or the ID. Added support for this in both client and server.
187 Affected files silcd/command.c and lib/silcclient/command.c
190 * Optimized the WHOIS and WHOWAS commands in the server. Removed
191 the _from_client and _from_server functions. Affected file
194 * Added silc_client_get_channel_by_id_resolve to the file
195 lib/silcclient/silcapi.h to resolve channel information by
196 its ID. Added also silc_client_get_channel_by_id that
197 does not resolve it from the server.
199 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
201 * Added SilcServerEntry context into the client library
202 to represent one server. The INFO command now allocates
203 these to save the resolved server info. For now on the
204 client library will also keep information about servers,
205 connected and resolved with INFO.
207 The INFO command now allocates the SilcServerEntry context
208 and saves the server info there. The COMMAND_REPLY in
209 the INFO now returns the parameters to application in
210 same order as defined in the protocol specification.
212 The entries are cached in the client->server_cache.
214 * The INFO command is now issued after received the Client ID
215 from the server. Affected file lib/silcclient/client.c.
217 * The CMODE_CHANGE notify may now return also an SilcServerEntry
218 to the application as the mode changer might be server.
219 It is guaranteed that NULL is not returned anymore to the
220 application. Affected file lib/silcclient/client_notify.c.
222 The ID Type is now also passed to the application so that
223 it can check whether the returned entry is SilcClientEntry
226 Added new function silc_client_get_server_by_id to return
227 the server entry by ID. Affected files are the
228 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
230 * Do not create the channel in the Irssi SILC Client when issuing
231 the JOIN command but when received the sucessful JOIN command
232 reply. Otherwise the channel might get created even though we
233 could not join it. The Affected file is
234 irssi/src/silc/core/[silc-channels.c/client_ops.c].
236 * Fixed a channel joining bug in router. The router must also
237 check the channel modes, invite and ban lists etc. when serving
238 the JOIN command sent by normal server. Affected file is
239 silcd/command.c. The router now resolves the client's
240 information from the server who sent the JOIN command if it
241 does not know it, and processes the JOIN command only after
244 * Changed the SilcCommandCb to take new argument; void *context2.
245 Affected file lib/silccore/silccommand.h
247 The second argument in the command callbacks in the server now
248 includes the SilcServerCommandReplyContext if the command was
249 called as pending command callback from the command reply.
250 Otherwise it is NULL. When called as pending the status of the
251 command reply will be checked and if it was erronous the
252 error will be sent to the original sender of the command.
253 This way the client always receives the error messages even
254 though the server was actually the one who received the error
255 when it resent the command to router, for example. Affected
256 files silcd/command[_reply].[ch].
258 * Fixed sending WHOWAS command's error message to client if
259 the requested client could not be found. It was missing.
262 * Changed the CMODE and CUMODE commands reply arguments in the
263 protocol specification. The Channel ID is now sent in both
264 of the commands to identify the channel. Implemented this
265 new feature to the client and server. Affected files
266 lib/silcclient/command_reply.c and silcd/command.c.
268 * Made better checks for invite and ban lists in the JOIN
269 command in server. Affected file silcd/command.c.
271 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
273 * The server now performs the incoming host IP/DNS lookup
274 using the silc_socket_host_lookup and thus does not block
275 the server anymore. Affected file silcd/server.c.
277 * Completed the multi-thread support for SILC Scheduler in
278 the lib/silcutil/silcschedule.c.
280 * Fixed the configure.in.pre to detect the pthread correctly
283 * Fixed a deadlock in silc_task_queue_wakeup in the file
284 lib/silcutil/silctask.c.
286 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
288 * Added new function silc_schedule_wakeup that is used in
289 multi-threaded environment to wakeup the main thread's
290 schduler. It needs to be used when a thread adds a new task
291 or removes a task from task queues. After waking up, the
292 scheduler will detect the task queue changes. If threads
293 support is not compiled in this function has no effect.
294 Implemented the wakeup mechanism to both Unix and WIN32
295 systems. Affected files are lib/silcutil/silcschedule.[ch],
296 lib/silcutil/unix/silcunixschedule.c and the
297 lib/silcutil/win32/silcwin32schedule.c.
299 * Added new function silc_task_queue_wakeup to wakeup the
300 scheduler by the specified task queue. Affected file
301 lib/silcutil/silctask.[ch].
303 * The silc_socket_host_lookup_start now wakes up the scheduler
304 after adding the timeout task. Affected file is
305 lib/silcutil/silcsockconn.c.
307 * The silc_socket_host_lookup is synchronous now if the threads
308 support is not compiled in. However, the callback is still
309 called asyncronously through the scheduler, anyway. Affected
310 file lib/silcutil/silcsockconn.c.
312 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
314 * Added new function silc_socket_host_lookup to perform
315 asynchronous IP and FQDN lookups for the socket connection.
316 Affected files lib/silcutil/silcsockconn.[ch].
318 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
320 * Added SILC_MUTEX_DEFINE to define the mutex on environments
321 that may or may not compile the mutex support in.
323 Changed the silc_mutex_alloc interface. It allocates the
324 mutex now to the sent pointer and returns TRUE or FALSE.
326 Affected file lib/silcutil/silcmutex.h.
328 * Wrote the SILC Task Queue interface to support multi-threads.
329 Affected file lib/silcutil/silctask.[ch].
331 * Wrote the SILC Scheduler to support multi-threads. Affected
332 file lib/silcutil/silcschedule.c.
334 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
336 * Implemented the SILC Mutex API and SILC Thread API for WIN32
337 in lib/silcutil/win32/.
339 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
341 * Defined SILC Mutex API and SILC Thread API and implemented
342 them for Unix. Affected files are
343 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
344 lib/silcutil/unix/silcunixmutex.c and
345 lib/silcutil/unix/silcunixthread.c.
347 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
349 * Fixed the silc_server_remove_clients_by_server's channel
350 key re-generation. The hash table handling was incorrect
351 and would not work with many channels. Affected file is
354 * Fixed some memory leaks around the server code.
356 * Rewrote the silc_server_get_users_on_channel to support IPv6
357 based Client ID's. Affected file silcd/server.c.
359 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
360 specification. However, a separate document must be written
361 to define the detailed signing procedure and the payload
362 associated with the flag. Defined the flag to the
363 lib/silccore/silcchannel.h as well.
365 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
367 * Changed the dynamic tables to static size tables in the
368 lib/silccrypt/silchmac.c.
370 * Removed GCC dependencies from the code. A patch by cras.
372 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
374 * Do not show the error "Error receiving packet bla bla"
375 in server if it really was not an error (-2 means that reading
376 is pending). Affected file silcd/server.c.
378 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
380 * Fixed a possible crash in silc_server_remove_clients_by_server
381 in silcd/server.c. Fixed there also some memory leaks.
383 * Fixed the silc_idlist_replace_client_id. It could replace
384 wrong key in the hash table. Affected file silcd/idlist.c.
386 * Do not check whether there are global users on the channel
387 if the channel->global_users is FALSE. Affected functions
388 silc_server_remove_from_one_channel and
389 silc_server_remove_from_channels in silcd/server.c. Also,
390 do not check if the removed client is local as we can be
391 sure that global client was not removed from the channel
392 and checking for global users is not needed.
394 * The silc_server_remove_clients_by_server now re-generates
395 the channel keys correctly for those channels that had
396 clients removed from them. Affected file silcd/server.c.
398 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
400 * Found the reason of random crashes in the server. We weren't
401 ignoring the SIGPIPE signal (which can be sent in write())
402 and it crashed the server. Affected file silcd/silcd.c.
404 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
406 * Assure that sock->user_data is not NULL in the function
407 silc_server_packet_send in silcd/packet_send.c.
409 * Disconnect the remote connection if it could not be added
410 to any ID lists in the server. The affected file is
413 * Check in silc_server_packet_send[_real/dest] that the
414 socket is not disconnecting and ignore the data if it is.
415 Affected file silcd/packet_send.c.
417 * Define inline to __inline on native WIN32 compilation.
418 Affected file includes/silcwin32.h.
420 * Added some explicit type casts for inline code since MSVC
421 require them. Affected files lib/silcutil/silcbuffer.h,
422 lib/trq/silcdlist.h and lib/trq/silclist.h.
424 * Print warning in log files from now on if the packet
425 decryption fails. Affected file silcd/server.c.
427 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Changed the `say' client operation's interface to accept
430 new `type' argument to indicate the type of the message sent
431 by the library. The application may filter the library's
432 messages according the type. The affected file is the
433 lib/silcclient/silcapi.h.
435 * Added two new functions to lib/silcclient/silcapi.h:
436 silc_client_del_client and silc_client_del_client_by_id.
437 Affected file lib/silcclient/idlist.c.
439 * Moved the clientincludes.h from includes/ to silc/ and
440 serverincludes.h from includes/ to silcd/.
442 * The modes for the CMODE and CUMODE are now passed as
443 uint32 for application with COMMAND_REPLY. The affected
444 file is lib/silcclient/command_reply.c.
446 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
448 * /WHOIS without arguments shows client's own information.
449 Affected file lib/silcclient/command.c.
451 * Changed PING to not accept any arguments. The specs
452 says that client can ping only the connected server so
453 requiring an argument is not needed. Affected file is
454 lib/silcclient/command.c.
456 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Fixed a fatal bug in private message sending and reception
459 encryption and decryption when using private message keys.
460 The implementation was incorrect and did not follow the
461 specification. It causd that some of the message were
462 lost since it did not use the sending and receiving keys
463 as the protocol suggests. This has been fixed and will cause
464 incompatibilities with older clients when sending private
465 message encrypted with private message keys. Affected files
466 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
467 and various other in Irssi SILC Client.
469 Added `responder' boolean argument to the functions
470 silc_client_add_private_message_key[_ske] to indicate when
471 the key is added as responder or initiator of the key
474 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Removed the silc_ske_check_version function and created
477 a SilcSKECheckVersion callback. Added also a function
478 silc_ske_set_callbacks that is now used to set all SKE
479 callbacks. The callback functions are not given to
480 the SKE functions anymore, but this function is used to
483 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
485 * Added `silc_version' argument to the silc_client_alloc
486 to define the version of the application for the library.
487 The library will use the version string to compare it
488 against the remote host's (usually a server) version
489 string. Affected file lib/silcclient/silcapi.h
491 * Added the KE protocol context to Key Agreement context
492 in client library so that we can abort the SKE if it
493 is in process when we get timeout. Affected file is
494 lib/silcclient/client_keyagr.c.
496 * Do not resolve the client ID forever if it returns in the
497 first time that such client does not exist. This was done
498 for example with private message. Affected file is
499 lib/silcclient/client_prvmsg.c.
501 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
503 * Do not add regex.h for WIN32. The affected file
504 includes/silcincludes.h.
506 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
507 not work yet 100%. It generates the DLL's automatically
508 when compiling with --with-win32 under cygwin.
510 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
512 * lib/contrib/regex.c is not compiled on WIN32.
514 * Added silc_net_get_socket_opt function to the
515 lib/silcutil/silcnet.h.
517 * Added includes/silcwin32.h for WIN32 specific includes
520 * Do not use ptime structure or any of the posix process
521 functions on WIN32 in lib/silccrypt/silrng.c.
523 * Added silc_gettimeofday to provide generic function
524 for struct timeval on all platforms. Added the function
525 to lib/silcutil/silcutil.h.
527 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Moved the lib/silccore/silcsockconn.[ch] to the utility
530 library as they clearly belong there. As a plus side we
531 can make the actual socket connection routines platform
534 Added also new generic function silc_socket_read and
535 silc_socket_write (that used to be silc_packet_[read/write].
536 The implementation of these are platform specific.
538 * Added WIN32 specific routines of silc_socket_[read/write]
539 to lib/silcutil/win32/silcwin32sockconn.c.
541 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
543 * Added preliminary support for native WIN32 compilation under
544 cygwin (using the -mno-cygwin option for GCC) to the
545 ./configure.in.pre. The --with-win32 now prepares the
546 compilation for native WIN32.
548 * Rewrote the SILC Scheduler interface in the file
549 lib/silcutil/silcschedule.h. The scheduler is now context
550 based and does not have anymore any global static scheduler.
551 Moved the Unix scheduler to the lib/silcutil/unix/ directory
552 and created lib/silcutil/win32 directory for WIN32 based
555 * Added Unix specific network routines to the
556 lib/silcutil/unix/silcunixnet.c and the old
557 lib/silcutil/silcnet.c includes now only generic routines.
559 Added WIN32 specific network routines to the
560 lib/silcutil/win32/silcwin32net.c.
562 * Added Unix specific utility functions from the
563 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
565 * Added WIN32 SILC Scheduler to the file
566 lib/silcutil/win32/silcwin32schedule.c. The code is of course
569 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
571 * Do not handle JOIN notify in the server if the target client
572 is not registered (idata->registered == FALSE). The affected
573 file is silcd/packet_receive.c.
575 * Update the nickrec->founder in event_cumode in the Irssi SILC
576 client. Affected file irssi/src/silc/core/silc-channels.c.
578 * Fixed the CUMODE_CHANGE notify handling in the server when
579 server and router are announcing their clients on channels.
580 Now the mode changes are saved and notified correctly. The
581 affected file is /silcd/packet_receive.c.
583 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
584 They really did not replace the cache entry in the ID Cache.
585 Now they do that. Affected file silcd/idlist.c.
587 * Fixed the KICK notify handling in the Irssi SILC client to
588 update the channel records so that the kicked client does not
589 appear to be on the channel. The affected file is
590 irssi/src/silc/core/silc-channels.c.
592 * Always update the conn->current_channel when executing command
593 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
595 * Fixed the KILL notify handling in Irssi SILC client to remove
596 the killed client on all channels.
598 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
600 * Fixed the silc_parse_command_line to remove extra spaces
601 from the start and end of the arguments. Affected file is
602 lib/silcutil/silcutil.c.
604 * Cancel and free any active protocol in the function
605 silc_server_close_connection. Affected file silcd/server.c.
607 * Cancel and free any active protocol in the function
608 silc_client_close_connction. Affected file is
609 lib/silcclient/client.c.
611 * Do not execute the KILL command for clients that are in
612 history (ie. they are not in the network). Affected file is
615 * Fixed KILL notify handling, client does not crash anymore.
616 Affected file irssi/src/silc/core/silc-channels.c.
618 * Reduced the default packet buffer size from 2048 to 1024 in
619 lib/silccore/silcpacket.c.
621 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
622 counter to the SKE context that is incresed when the SKE library
623 performs async operation outside the library. If the outside
624 process frees the SKE context and FREED status will be set
625 and the library will detect after the sync operation that the
626 libary is freed. The affected files are
627 lib/silcske/silcske[_status].[ch].
629 * Resolve the client entry information in the function
630 silc_client_channel_message to assure that NULL pointer is not
631 passed as client entry to the application. */
633 * Fixed the task timeout calculation to assure that there is
634 never negative timeouts. The affected file is
635 lib/silcutil/silcschedule.c.
637 * Fixed the channel user mode notification sending in server.
638 It was sent point-to-point to the router (or to server by router)
639 but it needs to be destined to a channel. The routines now
640 supports sending the channel user mode notifys to the channels
641 when announcing clients and channels. Affected files are
642 silcd/server.c and silcd/packet_receive.c.
644 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
645 It did not actually replace the old channel entry in the cache.
646 Affected file lib/silcclient/client_notify.c.
648 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Fixed a possible crash in silc_packet_send_prepare. It now
651 assures always that there is enough space in the buffer and
652 at the tail area of the buffer (for MAC).
654 Fixed the inbound buffer reallocation in silc_packet_read.
655 It was old code and did not handle the reallocation correctly.
658 The affected file is lib/silccore/silcpacket.c.
660 * Fixed buffer overflow in silc_parse_nickname in the file
661 lib/silcutil/silcutil.c.
663 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * make install generates new server keys only if there is not
668 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
671 Added check that if the NOREPLY is set then we will not send
672 the away message. This avoids infinite loop of away messages
673 if both clients are away. The affected file is
674 lib/silcclient/client_prvmsg.c.
676 * Fixed client crash if /NICK was given without arguments.
677 Affected file lib/silcclient/command.c.
679 * Server does not send the invite list in INVITE command back
680 to the client if the list was not altered. Added this notion
681 to the protocol spec as well. Affected file silcd/command.c.
683 Fixed possible crash in INVITE command by checking the
684 value of silc_server_get_client_route command.
686 * Fixed the INVITE notify type handling. The arguments are now
687 taken in correct order and client does not crash. The affected
688 file is irssi/src/silc/core/silc-channels.c.
690 Removed the "Inviting xxx to channel" message from the
691 client library away and let the application handle it.
692 Affected file lib/silcclient/command.c. Added that message
693 to Irssi SILC client's message formats.
695 * Fixed CMODE command crash in client. It now checks the
696 amount of arguments correctly and does not crash. The affected
697 file is lib/silcclient/command.c.
699 * Do not create new channel automatically in silc_channels_join
700 but check whether the channel by that name already exists.
701 Affected file irssi/silc/core/silc-channels.c.
703 * Do not send the SERVER_SIGNOFF to router if the disconnected
704 entity was the router. Affected file silcd/server.c.
706 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
707 SILC client as it was missing from there.
709 Added the handling of the KICK notify to the Irssi SILC client
710 as it was missing. Added "you have been kicked" message to
711 Irssi SILC client's message modules formats.
713 Added the handing of the KILL notify to the Irssi SILC client
714 as it was missing. Added the kill message module formats
717 The affected file is irssi/src/silc/core/silc-channels.c.
719 * The router did not save the channel mode the server announced.
720 Affected file silcd/packet_receive.c.
722 * Fixed a possible crash in INFO command in server. If the
723 server did not provide the server info it crashed. Affected
724 file silcd/command.c.
726 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
728 * Fixed the GETKEY command in the server to check also the
729 global list. Otherwise the GETKEY would not work correctly
730 in normal SILC server. Affected file silcd/command.c.
732 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Fixed GETKEY crash, it crashed if the command did not succseed.
736 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
739 is now real and not just an macro interface to GMP.
741 Removed the entire GMP from the source tree and imported new
742 NSS MPI library instead. Reason for removing GMP is that it is
743 extremely large and compiles extremely slow. The NSS MPI
744 is only a few files and compiles in less than 10 seconds.
745 The speed is also about the same as GMP. The MPI is imported
748 If the system has GMP installed we will still use the GMP.
749 If it is not then the NSS MPI will be compiled.
751 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Merged a long nickname (127 characters long) crash bugfix from
754 Irssi CVS tree. Affected file irssi/src/core/misc.c.
756 * Merged a freed memory reference bugfix from Irssi CVS tree.
757 Affected file irssi/src/core/commands.c.
759 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Added the server's public key sving and verification to the
762 server when performing the SKE. This was missing and the
763 remote server's (or router's) public key was accepted without
764 checking whether we have it previously or trust it at all.
765 Affected file silcd/protocol.c.
767 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
769 * Check in the silc_server_timeout_remote if protocol is active
770 and make sure that the protocol's final callback is called so
771 that all memory if freed. Affected file silcd/server.c.
773 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
775 * silc_server_whois_send_reply crashed the server if the nickname
776 was 127 characters long. Affected file silcd/command.c.
778 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Added sanity check to the silc_server_new_client. If the hostname
781 is provided inside username then check that the provided hostname
782 really is the same as the resolved one. If the hostname was not
783 resolved then check it from the public key. Affected file is
784 silcd/packet_receive.c.
786 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
787 if the server disconnected us and the connection is not valid
788 anymore. Affected file irssi/src/silc/core/silc-channels.c.
790 * Moved the silc_client_[chmode|chumode|chumode_char] away from
791 the library to the lib/silcutil/silcutil.[ch].
793 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Close log file after open. Affected file
796 lib/silcutil/silclog.c.
798 * Check whether sock == NULL in silc_client_send_packet and return
799 if it is. Affected file lib/silcclient/silcclient.c.
801 * Check rec->entry == NULL in the Irssi SILC Client before
802 sending the channel message. Affecte file is
803 irssi/src/silc/core/silc-servers.c.
805 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Merged a splitted window bugfix from Irssi CVS tree. The
808 affected file is irssi/src/fe-text/textbuffer-view.c.
810 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
811 It did not print nickname.
813 * Improved the distributions system a bit.
815 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
818 irssi/src/fe-text/gui-window.c.
820 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
821 to in-active server. The affected file is
822 irssi/src/silc/core/client_ops.c.
824 * Resolve the client in USERS command reply if the entry does
825 not have username resolved. The affected file is
826 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
827 command to WHOIS command to really resolve stuff. The USERS
828 is not used any more in any critical section so WHOIS can
829 be used even though it might be slower than IDENTIFY.
831 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
834 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Changed the protocol API a bit more consistent in the
837 lib/silccore/silcprotocol.[ch].
839 * Changed the following headers to ROBODoc format:
841 lib/silccore/silcpayload.h
842 lib/silccore/silcprotocol.h
843 lib/silccore/silcsockconn.h
845 All core library headers are now formatted.
847 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Fixed a bug in Irssi SILC client; do not show that you are
850 server/router operator if you really are not. Affected file is
851 irssi/src/silc/core/client_ops.c.
853 * Renamed silc_command_free_payload to silc_command_payload_free.
854 Affected file lib/silccore/silccommand.h
856 * Added silcmath.h to include the prototoypes of various routines
857 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
860 * Changed the following headers to ROBODoc format:
862 lib/silccore/silcchannel.h
863 lib/silccore/silccommand.h
864 lib/silccore/silcid.h
865 lib/silccore/silcidcache.h
866 lib/silccore/silcmode.h
867 lib/silccore/silcnotify.h
868 lib/silccore/silcpacket.h
869 lib/silcmath/silcmath.h
871 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * Added checking to the server code not to start the server if
874 ciphers and stuff are not configured properly. Affected files
875 silcd/serverconfig.[h] and silcd/server.c.
877 * Changed the layout of the header files of the public interfaces
878 in the SILC libraries. The new layout supports ROBODoc
879 documentation tool (and some others) so that it is easy to create
880 a library reference manual. All the other headers and source
881 code must still follow the CodingStyle document. Also source
882 code must not include these ROBODoc stuffs, only the headers.
883 Furthermore, all public interface headers must now be named
884 by using `silc' prefix, example: silcapi.h, silccipher.h.
885 Some files were renamed due to this. All the other headers
886 must not be used as public interfaces. I will update the
887 CodingStyle document later. Changed following headers, so far:
889 lib/silcclient/silcapi.h
890 lib/silccore/silcauth.h
891 lib/silccore/silcprivate.h
892 lib/silccrypt/silcdh.h
894 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Removed silc_client_packet_send_flush from the client library
899 as it is not needed. Affected file lib/silcclient/client.[ch].
901 * Added printing of message of unresolved authentication method
902 to the Irssi SILC client. Added it to the module formats.
903 Removed the same message from the client library.
905 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Added new distribution feature, DISTLABEL. Every distribution
908 can define own preprocessor label that can be used in the
909 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
910 file distributions, acconfig.h.pre and prepare.
912 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added Makefile.defines_int to include the actual definitions
915 for Makefile.defines.in. Tested the new distribution system,
916 created distributions and tested installation.
918 * Added AWAY message printing to the Irssi SILC client. Added
919 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
921 * Added SCONNECT command to call the SILC's CONNECT command.
922 Cannot use CONNECT directly since Irssi uses that internally.
923 Affected file irssi/src/silc/core/silc-servers.c.
925 Added ACTION local command. It is same as ME command but takes
926 the channel as mandatory argument.
928 Rewrote some of the Irssi's help files to suite for SILC
931 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Added Makefile.defines[.in] that should for now on be included
934 in all Makefile.am file in the source tree. That file includes
935 all common compilation definitions for SILC source tree.
937 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Minor changes to the ./prepare script to change the package
940 name according the distribution name to the configure.in.
942 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Created new distribution system. Added file `distributions'
945 that defines all the distributions that can be created out of
946 the SILC source tree. The ./prepare script now reads that
947 file to determine how to prepare the distributions. The
948 first argument to the ./prepare is the name of the distribution
949 and second is the version of the distribution. If given
950 without arguments it creates the default (toolkit) distribution
951 with the default version (defined in ./prepare).
953 All Makefile.am files that are subject to the distributions
954 are now named as Makefile.am.pre. These are ./Makefile.am
955 and lib/Makefile.am. Others may be changed later.
957 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Added invite list, ban list, some key management and connection
960 error message printing to module formats in the Irssi SILC client.
962 * Added new silc_client_set_away_message to set the away message
963 that is back to the person who sent private message. The
964 affected file lib/silcclient/silcapi.h and the
965 lib/silcclient/client_prvmsg.c.
967 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Fixed the private message sending in the Irssi SILC client,
970 added local command KEY to the Irssi SILC client.
972 Added key management and key agreement message formats to the
973 irssi/src/fe-common/silc/module-formats.[ch].
975 Added USERS (alias WHO) printing, server/router operator
976 indication and LIST command printing to the module formats.
978 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Fixed channel joining notify handling, cumode notify handling
981 from Irssi SILC client.
983 * Added SILC specific module-formats to the Irssi SILC client so
984 that SILC specific message hilighting, colors etc is possible.
985 Affected file irssi/src/fe-common/silc/module-formats.[ch].
987 Added channel mode, channel user mode, actions, notices,
988 whois and whowas printing to the the module-formats.c.
990 * Fixed a bug in channel deletion in the server. The channel
991 is not left to the cache even if the channel founder auth mode
992 is set when there are no users anymore on the channel. Affected
995 * The silc_net_localhost now resolves the entire hostname including
996 the domain name. Affected file lib/silcutil/silcnet.c.
998 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1000 * Changed the ask_passphrase client operation to be ascynchronous.
1001 It has now a completion callback and a context that the
1002 application must call after it has got the passphrase from
1003 the user. Affected files lib/silcclient/silcapi.h,
1004 lib/silcclient/protocol.c, lib/silcclient/command.c and
1007 Added SilcAskPassphrase callback that the application calls
1008 to deliver the passphrase to the library.
1010 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1011 The public key verification and especially a certificate
1012 verification is asynchronous procedure.
1014 Added new SILC_SKE_STATUS_PENDING status to indicate the
1015 request is pending and a callback will be called to finalize
1018 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1019 indicate that remote end did not send its public key (or
1020 certificate), even though we require it. Added check for this
1021 condition in the SKE. This was a security bug, now fixed.
1023 Defined new SilcSKEVerifyCbCompletion callback that is called
1024 when the verification process is completed.
1026 The affected files lib/silcske/silcske_status.h and
1027 lib/silcske/silcske.[ch].
1029 * Changed the verify_public_key client operation to be async
1030 as well. Defined SilcVerifyPublicKey callback that is used to
1031 indicate the success of the public key verification process.
1033 Changed the server and client to use the new async client
1036 * Changed the Irssi SILC client's internal scheduler to be called
1037 twice as many times as it used to be. As a result the client
1038 should be a bit faster now. Affected file is
1039 irssi/src/silc/core/silc-core.c.
1041 * Added support to Irssi SILC client of asynchronous public key
1042 verification and passphrase inquiry. Affected file is
1043 irssi/src/silc/core/silc-core.c.
1045 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Do not say "You have left channel %s" in client library.
1048 Moved it to the application. Affected files are
1049 lib/silcclient/command.c and silc/client_ops.c.
1051 * Fixed silc_client_get_clients. Command context was not
1052 duplicated and was freed memory in the callback. Affected
1053 file lib/silcclient/idlist.c.
1055 * Do not say "you are now talking..." on JOIN command in the
1056 client library. The appliation must handle it.
1058 * Do not say ".. changed topic to" in command reply in the
1059 client libary. The application must handle it.
1061 * Fixed TOPIC command sending in the client library.
1063 * Fixed a memory leak in silc_client_command_free in the file
1064 lib/silcclient/command.c.
1066 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Imported a modified version of Irssi client to the source tree.
1069 The Irssi will be used to create a new client called
1070 Irssi SILC. Imported to irssi/.
1072 Added silc_core_init_finish function to the Irssi. Affected
1073 file irssi/configure.in.
1075 A lot changes in the Makefile.ams around the irssi tree.
1077 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Do not rehash if the new size is same as the old size of the
1080 hash table, in the silc_hash_table_rehash*. The affected file
1081 lib/silcutil/silchashtable.c.
1083 * Replaced hash_table_del_by_context calls from the server
1084 (when channel->user_list and client->channels) to the
1085 hash_table_del as it is sufficient and faster.
1087 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1089 * Added silc_hash_table_list, silc_hash_table_get and the
1090 SilcHashTableList structure to provide an alternative way to
1091 traverse the hash table. The affected files are
1092 lib/silcutil/silchashtable.[ch].
1094 * Changed the server's idlist routines to use the hash table
1095 routines to optimize the code.
1097 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Replaced the client entry's `channel' list and channel entry's
1100 `user_list' list to hash tables for optimized lookup. Changed
1101 the code to use the hash table interface around the code.
1102 Affected file lib/silcd/idlist.[ch].
1104 * Added `auto_rehash' boolean argument to the function
1105 silc_hash_table_alloc to indicate whether the hash table should
1106 auto-rehash when it thinks is appropriate time. It will
1107 increase the hash table size if the there is twice as much
1108 entries in the table than the size of the table, and will
1109 decrease the size if there are twice as less entries than
1110 the size of the table.
1112 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1116 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * silc_idcache_purge_by_context deletes the entry now by context
1119 as it is supposed to do. Affected file lib/silccore/idcache.c.
1121 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1122 client is not anymore valid (WHOWAS givens the info) and not
1123 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1125 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Removed the `data' and `data_len' arguments from the ID Cache
1128 interfaces and added `name' argument. ID Cache does not handle
1129 anymore the binary data only a names associated with given ID.
1131 * When hashing a Client ID with silc_hash_id the entire ID is
1132 not hashed anymore, instead only the hash of the Client ID is
1133 hashed. This way we can access the Client ID from the cache
1134 with Client ID but with the hash of the ID (which is a hash of
1135 the nickname) as well without any difference in performance.
1137 Added also silc_idcache_find_by_id_one_ext to do one on one
1138 searching when we have the actual ID. Added also function
1139 silc_hash_client_id_compare. The affected files are
1140 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1142 * When hashing the name associated with a ID it is always done
1143 in lowercase. This way we can access the cache without worrying
1144 about case-sensitivity, even though, for example nicknames are
1147 * Fixed a bug in server with channel message sending. It put
1148 wrong ID type as destination ID. The affected file
1149 silcd/packet_send.c.
1151 * silc_idcache_del_by_context now deletes from all hash tables
1152 by context. Affected file lib/silccore/idcache.c.
1154 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Changed the client library to use the new ID Cache interface.
1157 Changes around the source tree.
1159 * Added silc_hash_table_rehash_ext to rehash with specific
1160 hash function. Affected file lib/silcutil/silchashtable.[ch].
1162 * Added silc_hash_string_compare to compare two strings in the
1163 hash table. Affected file lib/silcutil/silcutil.[ch].
1165 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Added new function silc_idcache_del_by_context into the
1168 lib/silccore/idcache.[ch].
1170 * Changed the server's ID list routines to use the new ID Cache
1171 interface. Changes around the source tree.
1173 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Added silc_hash_table_del[_by_context]_ext functions in to the
1176 lib/silcutil/silchashtable.[ch].
1178 Removed silc_hash_table_find_all* routines and added new
1179 silc_hash_table_find_foreach to replace them.
1181 Added silc_hash_table_replace_ext function as extended
1182 replacing function. Separated the simple hash table interface
1183 from the extended hash table interface in the file
1184 lib/silcutil/silchashtable.h.
1186 * Fixed minor bugs and changed it to use some of the new
1187 hash table functions in lib/silccore/idcache.c
1189 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * Added new function silc_hash_table_find_all to return all keys
1192 in the hash table by the specified key. As the hash table is
1193 collision resistant it also makes it possible to have several
1194 duplicate keys in the hash table. This function may be used to
1195 find all of the keys from the hash.
1197 Added user_context arguments to the SilcHashFunction,
1198 SilcHashCompare and SilcHashDestructor to deliver user specified
1201 Added new fuctions silc_hash_table_find[_all]_ext to do
1202 extended lookup with specified hash and compare functions and
1203 specified user contexts.
1205 Added new function silc_hash_table_add_ext to add the key
1206 with specified hash function and user context.
1208 Added new function silc_hash_table_foreach to traverse all
1209 entrys in the hash table. Added SilcHashForeach callback
1212 Added new function silc_hash_table_del_by_context to delete
1213 the entry only if the context associated with the key matches.
1215 Affected files are lib/silcutil/silchashtable.[ch].
1217 * Removed silc_hash_[server/client/channel]_id and added just
1218 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1219 silc_hash_id_compare to compare two ID's using as the hash table
1220 comparison function. Added also silc_hash_data to hash
1221 binary data and silc_hash_data_compare to compare it.
1223 * Removed silc_idlist_find_client_by_hash as it is not needed
1224 anymore. Affected file silcd/idlist.[ch].
1226 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1227 to use internally the SilcHashTable. The new ID Cache is a lot
1228 faster than the old one. Some of the ID Cache interface was also
1229 rewritten and obsolete and stupid functions were removed.
1231 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1233 * Added entry_count field to the SilcHashTable to keep the number
1234 of the entries in the table. Implemented the function
1235 silc_hash_table_rehash. Added new function
1236 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1238 Fixed a minor bug in silc_hash_table_free.
1240 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1241 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1242 into the lib/silcutil/silcutil.[ch].
1244 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Implemented a collision resistant hash table into the
1247 lib/silcutil/silchashtable[ch]. See the header and the source
1248 for the SilcHashTable API.
1250 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Merged dotconf version 1.0.2 into lib/dotconf.
1254 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1256 * Do not compile anything in lib/silcsim/* if the SIM support
1257 is not enabled. The tree should now compile without problems
1260 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Compiled the SILC under cygwin. Compiled and tested briefly
1263 without problems. More tests needed. The SIMs didn't compile
1266 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1268 * Fixed possible crash in silc_get_username in the
1269 lib/silcutil/silcutil.c.
1271 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Fixed a va_arg in silc/client_ops.c.
1275 * Oops, RC5 routines were named AES and caused some problems
1276 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1278 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * Added new SilcIDIP structure into the lib/silccore/id.h and
1281 replaced the old `ip' fields from all SILC ID's to that type.
1282 This is a step towards IPv6 support.
1284 The silc_id_get_len takes now the ID as an extra argument.
1285 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1286 both IPv4 and IPv6 based ID's.
1288 The affected files are lib/silccore/id.[ch] and other files
1289 around the tree using these routines.
1291 * Removed the ID length arguments in server from various
1292 silc_server_send_notify_* routines -> they are not needed
1295 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1297 * Fixed memory leak in silc_encode_pem_file in the file
1298 lib/silcutil/silcutil.c.
1300 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Check minor version as well in the SKE. Affected files are
1303 silcd/protocol.c and lib/silcclient/protocol.c.
1305 * Added --identifier option to the server so that an identifier
1306 can be when creating the public key for the server. Affected
1307 file is silcd/silcd.c.
1309 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1310 lib/silccrypt/silcpkcs.c.
1312 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Register default ciphers and stuff when using -C option with
1315 the server. Affected file sildc/silcd.c.
1317 * Put back the servers public key filename format, it is better
1318 than the new one. For now, the client keys are saved with the
1319 new filename format. The affected file silc/client_ops.c.
1321 * Implemented the Cipher API for the rest of the ciphers that
1322 did not implement it or implemented it the wrong way.
1324 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * Register default ciphers and stuff when using the -S option
1327 in the client. Affected file silc/silc.c. Same also when
1328 creating new key pair with -C option.
1330 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Fixed the silc_verify_public_key client operation function to
1333 save the public keys differently. The fingerprint is now
1334 used as filename and not the hostname. This way also the
1335 client keys are saved uniquely and not with hostnames. The
1336 affected file is silc/client_ops.c.
1338 * Trimmed the silc_hash_fingerprint function to remove extra
1339 whitespaces from the end of the fingerprint. The affected
1340 file is lib/silccrypt/silchash.c.
1344 * Added silc_cipher_register_default function to register all
1345 default ciphers. It can be used when configuration files
1346 does not exist and the application does not want any specific
1347 ciphers in any specific order.
1349 The SilcDList is now used as silc_cipher_list dynamically
1350 allocated cipher list. Removed the static list all together
1351 and now all ciphers must be allocated to the dynamic list.
1352 The silc_cipher_alloc routine was changed to check only the
1355 All silc_cipher_* routines that used to return int returns
1358 The affected files lib/silccrypt/silccrypt.[ch].
1360 * The same thing was done to silc_hash_* as for silc_cipher_*
1361 routines. Affected files lib/silccrypt/silchash.[ch].
1363 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1364 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1365 Added also silc_pkcs_[un]register[_default] functions.
1366 Removed the data_context from the PKCS API.
1368 * Added silc_hmac_register_default function to register default
1369 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1370 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1371 to unregister all hmacs at once.
1373 * Register the default ciphers, hash functions, PKCSs and HMACs
1374 if client's configuration file does not exist. The affected
1377 * The client did not load the hash functions from the SIM
1378 modules at all. Added support for this. Affected file is
1379 silc/clientconfig.c.
1381 * When decoding public key with silc_pkcs_public_key_decode, check
1382 the supported algorithm only if PKCS are registered. Affected
1383 file lib/silccrypt/silcpkcs.c. The same was done with the
1384 silc_pkcs_private_key_decode.
1386 * Fixed the SILC List routines to keep the list always in order.
1387 It used to change the list's order when traversing the list but
1388 not it preserves the order. Affected file lib/trq/silclist.h.
1390 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Added the client library to use the SilcSocketConnection's
1393 reference counter (by silc_socket_dup) to prevent the bug that
1394 the socket object may be freed underneath async operation.
1396 * The name resolv library checking fixes in the configure.in.pre.
1399 * Created new version of the protocol drafts for future
1400 development. The -03 drafts are the ones that will be changed
1401 in the trunk now and the -02 will remain as they are.
1403 * Send list of CUMODE notifys to the router when announcing
1404 the channel users to the router. Affected file silcd/server.c.
1405 If the router receiving channel founder CUMODE for a channel
1406 that already has channel founder it will send CUMODE notify
1407 to the sender to remove the channel founder rights from the
1408 announced client. Affected file silcd/packet_receive.c.
1410 * The CUMODE notify may now use Server ID as well as the entity
1411 who changes the mode. Updated protocool specs.
1413 * Updated INSTALL and README files.
1415 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * New web pages in the http://silc.pspt.fi. The pages was
1422 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Implemented the [DenyConnectin] config section in the server.
1425 Added silc_server_config_denied_conn to check whether incoming
1426 connection is denied. Affected file silcd/serverconfig.[ch].
1428 * Do not check the ports when checking the incoming configuration
1429 data if the port is 0, meaning any. Affected file is
1430 silcd/serverconfig.c.
1432 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Fixed buffer overflow in silc_string_compare in the file
1435 lib/silcutil/silcutil.c.
1437 * Fixed double free in silc_server_command_leave in the file
1440 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1442 * Fixed the version checking in the server. Affected file is
1445 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Fixed the configuration data fetching when accepting new
1448 connections in the server. Affected file silcd/server.c.
1450 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1452 * Added `sender_entry' argument to the function
1453 silc_server_packet_relay_to_channel so that we can check
1454 whether some destination actually belongs to the same route
1455 the sender belongs (ie, we must not resend the packet to the
1456 sender). Affected file silcd/packet_send.[ch].
1458 * Added `servername' field to the SilcClientEntry in the server
1459 to hold the name of the server where client is from. Affected
1460 file is silcd/idlist.h.
1462 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1464 * Moved the channel message encrypting in the router betwen
1465 router connections from silc_server_channel_message to the
1466 silc_server_packet_relay_to_channel since we want to check
1467 whether we have anybody channel before encrypting anything.
1468 Affected files silcd/packet_[receive/send].c.
1470 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Fixed the [AdminConnection] server config section to support
1473 multiple entries. Affected file silcd/serverconfig.c.
1475 * Added support into the server to check the validity of the
1476 incoming connection before executing any KE or authentication
1479 * The connection configuration is now saved to the KE and
1480 connection auth protocol contexts and not fetched anymore in
1481 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1483 * The local hosts listenning address and port is also resolved
1484 now when starting the server. We want to have the socket object
1485 to include the real address and port for the listener. Added
1486 new function silc_net_check_local_by_sock into the files
1487 lib/silcutil/silcnet.[ch].
1489 * Fixed a broadcast bug in server -> do not broadcast if we
1492 * Fixed a routing bug. Do not route broadcast packets ever.
1493 Broadcast packets must be processed always and not routed since
1494 they may be destined to some other host than yourself and thus
1495 would get routed without no good reason. Affected file is
1498 * Added function silc_server_config_is_primary_route to check
1499 whether primary router connection has been configured (a router
1500 configuration that we are initiating). If there is not, we
1501 will assume that there is only two routers in the SILC network
1502 and we will use the incoming router connection as our primary
1503 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1505 * Changed the order of the broadcasting. Broadcast _after_ the
1506 packet has been processed not before. Affected file is
1509 * Fixed a [ClientConnection] parsing bug. The port was never
1510 parsed correctly thus resulting to port 0. Affected file
1511 silcd/serverconfig.c.
1513 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1514 argument and did not set the broadcast packet flag. Affected
1515 file silcd/packet_send.c. Fixed same bug in the function
1516 silc_server_send_notify as well.
1518 * If we receive NEW_ID packet for our own ID in the server, ignore
1521 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Removed the nickname from the Private Message Payload.
1526 Updated the code and the protocol specs.
1528 * Updated protocol specs for submitting to the IETF.
1530 * Tweaked the Random Number Generator a bit. Affected file
1531 lib/silccrypt/silcrng.c. Exported a new function
1532 silc_rng_[global]_add_noise which can be used to add more
1535 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Do not parse packets with different timeout when protocol
1538 is active -> may cause problem with rekey. Affected file
1541 * When server receives signoff notify it must not create
1542 new channel key if the client is on any channels since the
1543 sender of the signoff notify will create it.
1545 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Added printing of error messages during SKE protocol from the
1548 failure packet sent by server during SKE. Affected file
1551 * Removed the client's failure_callback handling with timeout
1552 and handle it immediately when received.
1554 * The SKE library returned wrong type in SUCCESS and FAILURE
1555 packets. They must be 32 bit MSB not 16 bit MSB.
1557 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Ok, rewrote the logic of the re-key and now it seems to work.
1560 I tested it on high traffic with frequent re-keys without
1561 problems. Added hmac_receive (and renamed hmac to hmac_send)
1562 in SilcClientConnection in lib/silcclient/client.h and
1563 in SilcIDListData in silcd/idlist.h. Also, removed the
1564 SilcPacketParserContext's cipher and hmac fields as they are
1565 not needed anymore and actually caused some problems when
1566 the ciphers and hmac's changed underneath the packet parser.
1568 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * If re-key protocol is active then process the incoming packets
1571 synchronously since we must assure that icoming packets encrypted
1572 with the old key is processed before the new keys is set to
1573 use. This is true other packets than for REKEY packets.
1574 Affected file silcd/server.c. The same was done to client library
1575 as well, affected file lib/silcclient/client.c.
1577 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Fixed bug in client and server to accept the force send if
1580 the packet is send from silc_[server/client]_packet_process
1581 function. Otherwise the packets are never delivered, oops.
1583 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1585 * Disable force sending of packets when REKEY protocol is active.
1586 We must assure that no packet is sent directly when rekey is
1587 performed. All packets must be sent through packet queue.
1588 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1589 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1590 function is silc_[server/client]_packet_send_real to check
1593 * Replaced the SIM paths from example config files to
1594 /usr/local/modules. Also, make install creates now
1595 /usr/local/silc/logs directory to hold all the SILC server
1598 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Made the configure.in.pre work on Solaris. Patch by salo.
1602 * Made all ciphers compatible with non-x86 machines. Defined
1603 CBC mode macros into lib/silccrypt/ciphers_def.h.
1605 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * Fixed the make install.
1609 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1611 * When MAC computation fails the silc_packet_decrypt returned 0
1612 even though it was supposed to return -1. Fixed this. The
1613 affected file is lib/silccore/silcpacket.c.
1615 * Do not replace the config files in /etc/silc (in make install)
1616 if they already exist. Affected file ./Makefile.am.
1618 * Do not send re-key packets immediately but through packet queue.
1619 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1621 * Changed silc_net_check_host_by_sock to return FALSE if the
1622 IP/DNS could not be resolved. Though, it returns the IP address
1623 now even if it could not resolve it (but returns also FALSE).
1624 Affected file lib/silcutil/silcnet.[ch].
1626 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Added silc_pkcs_decode_identifier to decode the public key's
1629 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1630 Added also silc_pkcs_free_identifier. Added also new context
1631 SilcPublicKeyIdentifier.
1633 * Added -S option to the silc client. It is used to dump the
1634 contents of the specified public key file.
1636 * Changed the PKCS api to return the public key length when
1637 setting the public key.
1639 * Fixed a fatal bug in the public and private key file loading.
1640 Affected file lib/silccrypt/silcpkcs.c.
1642 * Execute the packet parsing for client with zero (0) timeout
1643 if the protocol is active. Affected file silcd/server.c.
1645 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * Made the key generation options to the silcd program. Added
1648 -C option, equivalent to client's option.
1650 * Added new [ServerKeys] config section to the server. It
1651 configures the server's public and private key.
1653 * Defined generic Public Key Payload into the protocol
1654 specification to send specific type of public keys and
1657 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1658 public key or certificate.
1660 * Implemented the GETKEY command to the server and to the
1661 client library and on user interface.
1663 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Made preliminary `make install' work.
1667 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Added SilcServerRekey context into silcd/idlist.h.
1671 * Added the PFS support as defined in the specification to the
1672 SKE protocol. Affected files lib/silcske/*.c.
1674 * Added `ske_group' field to the SilcServerRekey context to hold
1675 the number of the SKE group that is used with PFS in re-key.
1676 Affected file silcd/idlist.h.
1678 * Added PFS re-key support to the server. Affected file is
1681 * Added silc_protocol_cancel to cancel execution of the next
1682 state of the protocol. Affected file is
1683 lib/silccore/silcprotocol.[ch].
1685 * Added the re-key support with and without PFS to the client
1686 library. Re-key is performed once in an hour, by default.
1688 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1689 Added silc_client_rekey_callback and silc_client_rekey_final.
1690 Affected files are lib/silcclient/protocol.[ch] and
1691 lib/silcclient/client.[ch].
1693 * Removed the `hmac_key' and `hmac_key_len' fields from the
1694 SilcClientConnection structure; not needed. Affected file is
1695 lib/silcclient/client.h.
1699 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Do not ask whether user wants to use the negotiated private key
1702 for private messages, just use it. Affected file is
1703 silc/local_command.c.
1705 * Added `send_enc_key' and `enc_key_len' fields to the
1706 SilcIDListData structure since they are needed in the re-key
1707 phase. Affected file is silcd/idlist.[ch].
1709 * Implemented the simple re-key protocol into the server.
1710 Affected files silcd/server.c and silcd/protocol.[ch]. The
1711 re-key will be performed once in an hour, by default.
1713 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1714 Added silc_server_rekey, silc_server_rekey_callback and
1715 silc_server_rekey_final.
1717 * Removed Tunneled flag from the protocol. Updated the code
1718 and the specifications.
1720 * Adde `pfs' field to the SilcIDListData to indicate whether
1721 the PFS is to be performed in the re-key. Affected file is
1724 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1727 int64 of at least the xintXX size. If void * is less that 4
1728 bytes uint32 * will be used. Defined bool as boolean.
1730 * Changed _ALL_ unsigned long and unsigned int to uint32,
1731 unsgined short to uint16 in the source tree.
1733 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1734 not handle clients that has entry->data.registered == FALSE.
1735 They are not in the network anymore. Affected file is
1738 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Implemented the sending of the SERVER_SIGNOFF notify in the
1741 server. Affected file is silcd/server.c.
1743 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1744 Added also silc_notify_payload_encode_args into the
1745 lib/silccore/silcnotify.[ch].
1747 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1748 Affected file silcd/packet_receive.c.
1750 * Implemented the SERVER_SIGNOFF notify handling in the client
1751 library. Affected file lib/silcclient/client_notify.c. Also,
1752 implemnted the printing of the SERVER_SIGNOFF info to the
1753 application. Affected file silc/client_ops.c.
1755 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1756 if the deleting was successful. Affected file silcd/idlist.[ch].
1758 * Added support for public key authentication in the connection
1759 authentication protocol in the client library. Affected file
1760 lib/silcclient/protocol.c.
1762 * Changed the server's silc_idlist_get_clients_by_* interface
1763 to support already allocated array so that new entries may be
1764 added to pre-allocated array. Affected file silcd/idlist.[ch].
1765 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1766 and command replies.
1768 * All command reply functions in the server now calls the
1769 pending command callback even if error occured. This way the
1770 error will be delivered to the client as well. Affected files
1771 silcd/command.c and silcd/command_reply.c.
1773 * Fixed INFO command to return local server's info if no server
1774 was provided. Affected file lib/silcclient/command.c.
1776 * Removed RESTART command for good. Updated the code and the
1779 * Rewrote parts of the task system. It is a bit simpler now.
1780 Removed unsued task priorities. The affected files are
1781 lib/silcutil/silctask.[ch].
1783 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Moved the USERS printing from the library to the application.
1786 Affected files lib/silcclient/command.c and silc/client_ops.c.
1788 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Added channel key re-key support. The re-key is perfomed
1793 only by the router and is done once in an hour. Added `rekey'
1794 field to the SilcChannelEntry in the server. Affected files
1795 silcd/server.c and silcd/idlist.h.
1797 * Added silc_task_unregister_by_context into the file
1798 lib/silcutil/silctask.[ch].
1800 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Added SILC_UMODE_GONE mode to indicate when the client is not
1803 present in the SILC network. Added also support to the local
1804 command AWAY that will set this mode. Added support of showing
1805 "xxx is gone" in WHOIS command. The USERS command shows the
1806 gone status as well.
1808 * Fixed setting server and router operator privileges in the
1809 server's UMODE command. Affected file silcd/command.c.
1811 * Merged the SKE KE1 and KE2 payloads into one payload. The
1812 new KE payload is equivalent to the old KE2 payload.
1814 Cleaned up the SKE Start Payload parsing. It now uses the
1815 simple buffer unformatting to do the parsing. A lot faster
1818 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1819 to the SKE that is used to indicate whether both of the SKE
1820 parties should perform authentication. By default only the
1821 responder performs authentication. By setting this flag also
1822 the initiator must do authentication. By default it is unset
1823 since in normal SKE case, client to server connection, only
1824 the responder should do authentication. When doing SKE between
1825 two clients both should perform authentication. Updated the
1826 code and the protocol specs.
1828 * A little fix to IDENTIFY command in the server. Search the
1829 client first by hash not nickname. Affected file is
1832 * Fixed the silc_client_close_connection to support closing
1833 the client to client connections wihtout deleting too much
1834 data. Affected file lib/silcclient/client.c.
1836 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1837 are received if protocol used to be active but is not anymore
1838 the application would crash due to NULL pointer dereference.
1839 Affected files silcd/server.c and lib/silcclient/client.c.
1841 * Added `hash' field to the SilcClientConnection to include
1842 the hash function negotiated in the SKE protocol.
1844 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1845 to set the channel founder authentication data. A client can
1846 claim the founder rights later by providing the authentication
1847 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1848 This way the channel founder can regain the channel founder
1849 privileges even it is left the channel. This works only on
1850 local server and the client must be connected to the same
1851 server to be able to regain the founder rights. Updated the
1852 protocol specs accordingly.
1854 Added support to the CMODE command in the client to set the
1855 founder auth data. Read the README to see how to set it.
1857 Added support to the CUMODE command to claim the founder
1858 rights. Read the README to see how to do it.
1860 Added support for the founder authentication to the Channel
1861 Entry in the server. Affected file silcd/idlist.h.
1863 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1864 server's CMODE command. Affected file silcd/command.c.
1866 * Added the following new functions into lib/silccore/silcauth.[ch]:
1867 silc_auth_get_method and silc_auth_get_data.
1869 * The server now saves the remote hosts public key to the
1870 SilcIDListData pointer. Affected file silcd/protocol.c.
1872 * The normal server now does not remove the channel entry from
1873 the cache if the founder authentication data is set. It used
1874 to remove it if the founder was the last one on the channel on
1875 the server and left the channel. The auth data is saved and
1876 if the channel is re-joined later the old entry is used with
1877 the old auth data. Affected files silcd/command_reply.c and
1880 * Removed the `pkcs' field from the SilcIDListData structure
1881 in the server; it is not used. Affected file silcd/idlist.h.
1883 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Fixed packet processing on slow links. Partial packets were
1886 never re-processed because the incoming data buffer was cleared
1887 by the application. Application must not directly clear the
1888 sock->inbuf, the packet processing routines handle it. Fixed
1889 this in client library and in server.
1891 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Fixed the WHOIS and IDENTIFY send reply function to really
1894 check whether to send list or just one entry. Affected file
1897 * Cleaned up the LEAVE command's channel key distribution. The
1898 affected file silcd/command.c.
1900 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1901 can enforce the channel mode as well. In that case the ID
1902 includes the ID of the server. The code now enforces the
1903 mode change if the router have different mode than the server.
1905 * The notify client operation with CMODE_CHANGE notify can now
1906 return NULL client_entry pointer if the CMODE was not changed
1907 by client. Application must check for this.
1909 * Added <Server ID> argument to INFO command to support server
1910 info fetching by Server ID.
1912 * Added silc_server_announce_get_channel_users to get assembled
1913 packets of channel users of the specified channel. Affected
1914 file silcd/server.[ch].
1916 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1917 was freed underneath the ID Cache.
1919 * Re-announce clients when the server received CHANNEL_CHANGE
1920 notify from the router. Affected file silcd/packet_send.c.
1922 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1925 crashed since it did not handle the fact that there is no cipher
1926 called "3" and didn't check the error condition. Now fixed.
1928 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1929 flag. It can be used to send message requests.
1931 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Implemented the RESTART command in the client.
1935 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1936 notice type messages. Added notice printing to the user
1939 * The channel keys are not re-generated if the channel's mode
1940 is PRIVKEY, ie private key on the channel exists. Affected
1941 files silcd/server.c and silcd/command.c.
1943 * Fixed a little bug in channel message delivery when channel
1944 private keys are set in the server. Affected file is
1945 silcd/packet_send.c.
1947 * Changed the setting on channel->on_channel = TRUE from the
1948 silc_client_save_channel_key to the JOIN command reply. The
1949 key payload is not received if the private channel key is set.
1950 Affected file lib/silcclient/command_reply.c and the
1951 lib/silcclient/client_channel.c.
1953 * When the CMODE_CHANGE notify is sent and the channel private
1954 key mode is removed the channel key must be re-generated in
1955 other cells as well. Added this support for the router in the
1956 silcd/packet_receive.c.
1958 * Added new local command NOTICE to send notice message on
1959 channel. Affected file silc/local_command.[ch].
1961 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added new local command ME to the client. It is used to send
1964 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1965 some action. Affected file silc/local_command.[ch].
1967 * Changed channel_message and private_message client operations
1968 to deliver the message flags to the application. Added also
1969 the `flags' arguments to the silc_client_send_channel_message
1970 and silc_client_send_private_message functions. Affected file
1973 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Redefined the Private Message Payload to support private message
1976 keys and to support the new private message flags. Updated
1977 the protocol specs. Flags makes it possible to have for example
1978 CTCP style messages.
1980 * Added new type SilcPrivateMessagePayload and defined an API
1981 for it in the lib/silcclient/silcprivate.[ch].
1983 * Tested private message private keys successfully. Tested the
1984 private message key set, unset and list commands with the new
1987 * Redefined the Channel Message Payload to include the channel
1988 message flags (equal with private message flags) to support
1989 for example CTCP style messages.
1991 * Defined some of the message (for channel and private message)
1992 flags. Updated the protocol specs and added the flags to the
1993 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1995 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Added SilcKeyAgreementStatus type to the key agreement routines
1998 to indicate the current status and error if one occured.
1999 The status types are defined in the lib/silcclient/silcapi.h.
2001 * Added new local command KEY that is used to set and unset private
2002 keys for channels, set and unset private keys for private messages
2003 with remote clients and to send key agreement requests and
2004 negotiate the key agreement protocol with remote client. The
2005 key agreement is supported only to negotiate private message keys,
2006 it currently cannot be used to negotiate private keys for channels,
2007 as it is not convenient for that purpose.
2009 * Fixed a minor pending callback setting bug in the function
2010 silc_client_get_client_by_id_resolve, now the function works.
2011 Affected file lib/silcclient/idlist.c.
2013 * Added function silc_net_get_local_port to get local bound
2014 port by socket. Added to lib/silcutil/silcnet.[ch].
2016 * Added `sockets' and `sockets_count' fields to the SilcClient
2017 object. They hold the sockets of the listenning sockets in
2018 the client. Listenning sockets may be for example the key
2019 agreement server. Affected file lib/silcclient/client.[ch].
2020 Added functions the silc_client_add_socket and the
2021 silc_client_del_socket. They are exported to the application
2024 * Added ~./silc/clientkeys to support other client's public keys.
2026 * Renamed verify_server_key client operation to verify_public_key
2027 and added one argument to indicate the type of the connection
2028 (server, client etc.).
2030 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Added silc_server_connection_auth_request to handle the
2033 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2034 silcd/packet_receive.[ch].
2036 * Added silc_server_send_connection_auth_request into the
2037 silcd/packet_send.c to send the connection auth request packet.
2039 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2042 * Fixed the public key authentication in responder side in the
2043 server. The `auth_data' pointer includes the SilcPublicKey
2044 not the path to the public key. Affected file silcd/protocol.c.
2046 * Implemented the public key authentication in the initiator side
2047 in the server. Affected file silcd/protocol.c.
2049 * Removed the [RedirectClient] config section from the server
2050 configuration. Is not needed and I don't want to implement it.
2052 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Cleaned up the CMODE command in the server. It now works
2055 correctly and supports all the modes defined in the protocol.
2056 Affected file is silcd/command.c.
2058 * Added `hmac_name' field to the SilcChannelEntry in the server
2059 to hold the default HMAC of the channel. It can be set when
2060 creating the channel (with JOIN command). Affected files
2063 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2064 type to indicate the change of the current cipher and hmac
2065 on the channel. Client can safely ignore the <cipher> argument
2066 (if it chooses to do so) since the CHANNEL_KEY packet will
2067 force the channel key change anyway. The <hmac> argument is
2068 important since the client is responsible of setting the new
2069 HMAC and the hmac key into use.
2071 * Fixed the CMODE command in the client library as well.
2073 * Tested CMODE command in router environment successfully.
2075 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Show the version of the remote client (or server) when connecting
2078 to the server. It is logged to the log file. Affected file
2079 is silcd/protocol.c.
2081 * Fixed the KILLED notify handling in the client library. The
2082 client must be removed from all channels when receiving the
2085 Also, do not remove the client entry when giving the KILL
2086 command but when the KILLED notify is received.
2088 * Removed silc_idlist_find_client_by_nickname from the server.
2089 Not needed anymore. Affected files silcd/idlist.[ch].
2091 * Implemented the CHANNEL_CHANGE notify type handling to the
2092 server. Affected file silcd/server.c.
2096 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Added silc_server_send_notify_invite to send the INVITE
2099 notify between routers.
2101 * Implemented the INVITE command correctly to the server.
2103 * Implemented the INVITE notify type handling in the server.
2105 * Implemented the INVITE command to the client library and on the
2108 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2110 * Added function silc_server_get_client_resolve to find the
2111 client entry by ID from all ID lists and then resolve it
2112 (using WHOIS) if it cannot be found. Affected file is
2115 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Implemented the BAN command to the client library.
2119 * The JOIN command in the server now checks the invite list
2122 * Changed the silc_command_reply_payload_encode_va and the
2123 silc_command_payload_encode_va to support that if argument is
2124 NULL it ignores and checks the next argument. Affected file
2125 lib/silccore/silccommand.c.
2127 * Added silc_server_send_notify_ban to send the BAN notify
2128 type between routers.
2130 * Chaned the silc_notify_payload_encode to support that if
2131 argument is NULL it ignores and checks the next argument.
2132 Affected file lib/silccore/silcnotify.c.
2134 * Tested ban lists in router environment successfully.
2136 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Implemented BAN command to the server, in silcd/command.[ch].
2140 * Removed the BAN and INVITE_LIST modes from the CMODE command
2143 * Added function silc_string_match to regex match two strings.
2144 Affected files lib/silcutil/silcutil.[ch].
2146 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Redefined parts of the SilcChannelEntry in the server to support
2149 the new ban and invite lists.
2151 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Redefined the INVITE command. The same command can be used to
2154 invite individuals to the channel but also to manage the invite
2155 list of the channel (to add to and remove from the invite list).
2156 Updated the protocol specs.
2158 * Added new command SILC_COMMAND_BAN that can be used to manage
2159 the ban list of the channel. Updated the protocol specs.
2161 * Removed the channel modes: the SILC_CMODE_BAN and the
2162 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2163 in the CMODE command. The equivalent features are now available
2164 using INVITE and BAN commands. Updated the protocol specs.
2166 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2167 in the network about change in the current ban list. The notify
2168 type is not used by the client.
2170 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2171 support the invite lists.
2173 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Added new function silc_string_regexify that converts string
2176 including wildcard characters into regex string that can
2177 be used by the GNU regex library. Added into the file
2178 lib/silcutil/silcutil.[ch].
2180 Added silc_string_regex_combine to combine to regex strings
2181 into one so that they can be used as one regex string by
2182 the GNU regex library. Added into the file
2183 lib/silcutil/silcutil.[ch].
2185 Added silc_string_regex_match to match two strings. It returns
2186 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2188 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Imported GNU regex to the soruce tree into lib/contrib.
2191 Fixed some compiler warning from the regex.c.
2193 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2195 * Fixed MOTD command in the server to work in router environment.
2197 * Fixed the MOTD command in the client library to support
2198 the server argument in the command.
2200 * Added `nickname_len' argument to the silc_idlist_add_client
2201 in the server, as the `nickname' argument may be binary data
2204 * Added silc_idlist_get_channels to return all channels from
2207 * Implemented LIST command to the server. Affected file is
2210 * Implemented the LIST command to the client library and on the
2213 * Added [<user count>] argument to the LIST command reply.
2214 With private channels the user count is not shown.
2216 * Updated TODO and README.
2218 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * The client entry's data.registered must be TRUE even with
2221 global client entry on global client list. The data.registered
2222 is used to check whether the client is anymore in the network,
2223 for example with WHOWAS command so it must be valid.
2225 * Fixed the WHOWAS command in the server. It now actually works
2226 in router environment. Added function into silcd/command_reply.c
2227 silc_server_command_reply_whowas_save.
2229 * Added silc_idlist_purge function to the silcd/idlist.c
2230 to periodically purge the ID Cache.
2232 * Fixed INFO command in the server. It works now in router
2233 environment. Added <server name> argument to the INFO command
2234 reply. Updated the protocol specs.
2236 * Fixed minor bug in silc_idcache_purge to not purge if the
2237 expire value is zero.
2239 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2240 they were buggy because of the WHOWAS information.
2242 * Fixed local command MSG to handle the async resolving of
2243 the remote client properly. It used to fail the first MSG.
2244 Affected file silc/local_command.c.
2246 * Added `data_len' field to SilcIDCache context.
2248 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Update TODO. Todo in commands in the server.
2252 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2255 used by routers as broadcast packet to inform other routers
2256 about the changed user mode.
2258 Implemented the notify handling in the server. Affected file is
2259 silcd/packet_receive.c. Added the function
2260 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2262 * Added new generic Channel Payload and deprecated the New Channel
2263 Payload. The New Channel Payload is now the generic Channel
2266 * Added new argument `mode' to the silc_server_send_new_channel
2267 as it is required in the Channel Payload now.
2269 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2270 and created a new and real SilChannelPayload to represent the
2271 new generic Channel Payload. Implemented the encode/decode
2272 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2274 * Added silc_server_get_client_channel_list to return the list
2275 of channels the client has joined for WHOIS command reply.
2276 Affected file silcd/server.[ch].
2278 * Implemented the channel list sending in the WHOIS command reply
2279 in server and in the client.
2281 Implemented the channel list displaying on the user interface
2282 as well. Affected file silc/client_ops.c.
2284 * Added silc_channel_payload_parse_list to parse list of Channel
2285 Payloads. It returns SilcDList list of SilcChannelPayloads.
2286 Client for example can use this function to parse the list of
2287 channels it receives in the WHOIS command reply. The caller
2288 must free the list by calling silc_channel_payload_list_free.
2289 Affected files lib/silccore/silcchannel.[ch].
2291 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Added one new argument <user mode> to the WHOIS command reply
2294 to return the mode of the user in SILC. Updated the protocol
2297 Implemented it to the server and client.
2299 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Fixed the mode printing on the user interface on joining.
2302 Affected file silc/client_ops.c.
2304 * Implemented the UMODE command and user modes in general to the
2305 client library and to the user interface.
2307 * Implemented the UMODE command to the server.
2309 * The server now sends UNKNOWN_COMMAND error status if client sends
2310 unknown command. Affected file silcd/command.c.
2312 * All server commands now handle the command identifier the right
2313 way when sending the command reply to the client. The client can
2314 use to identify the command replies with the identifier.
2316 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Added silc_server_get_client_route to resolve the route to
2319 the client indicated by the client ID. Affected file is
2322 * Added silc_server_relay_packet as general function to relay
2323 packet to arbitrary destination. This deprecates functions
2324 like _send_private_message_key, _relay_notify etc. Affected
2325 file is silcd/packet_send.[ch].
2327 Removed silc_server_send_key_agreement,
2328 silc_server_send_private_message_key and
2329 silc_server_packet_relay_notify functions from the file
2330 silcd/packet_send.[ch].
2334 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2335 server. Affected file silcd/packet_receive.[ch].
2337 * Implemented the KILL command to the client. Implemented the
2338 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2339 Affected files lib/silcclient/command[_reply].c and
2340 lib/silcclient/client_notify.c. Implemented the KILL notify
2341 printing in the user inteface.
2343 * Fixed a lot silc_parse_nick memory leaks from the client
2344 library in the file lib/silcclient/command.c.
2346 * Changed the silc_server_send_notify_on_channels's `sender'
2347 argument from SilcSocketConnection to SilcClientEntry to
2348 check the sender as entry and not as connection object and not
2349 to send to the client provided as argument. The affected file
2350 is silcd/packet_send.[ch].
2352 * The notify packets that are destined directly to the client used
2353 to not to be processed by the server. Now changed that and the
2354 server processes all notify packets. After relaying the packet
2355 to the client the notify packet is processed in the server.
2357 * The silc_server_free_client_data now checks whether there is
2358 pending outgoing traffic for the client and purges the data to
2359 the network before removing the client entry.
2361 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2364 an client is killed from the SILC Network. Updated the protocol
2367 Added new function silc_server_send_notify_killed to the
2368 silcd/packet_send.[ch].
2370 * Added function silc_server_packet_relay_notify to relay notify
2371 packets that are destined directly to a client. In this case
2372 the server does not process the notify packets but merely relays
2373 it to the client. Affected file silcd/packet_send.[ch].
2375 Added also silc_server_packet_process_relay_notify to check
2376 whereto relay the notify. Affected file is
2377 silcd/packet_receive.[ch].
2379 * Implemented the KILL command to the server.
2383 * Added the backup schema desgined last fall to the protocol
2384 specs for everyone to see. The specification is in the
2385 *-spec-xx.txt draft and the packet type definitions for the
2386 backup routers is in *-pp-xx.txt draft. Thusly, added also
2387 new packet type SILC_PACKET_CELL_ROUTERS.
2389 * A big security problem in the implementation discovered. The
2390 signoff of an client did not cause new channel key generation
2391 which it of course should've done. The channel keys must be
2392 always re-generated when client leaves (or signoffs) the channel.
2393 The silc_server_remove_from_channels funtion now handles
2394 the channel key re-generation.
2396 * Added `sender' argument to the silc_server_send_notify_on_channels
2397 to not to send the client provided as argument. Affected file
2398 silcd/packet_send.[ch].
2400 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Implemented OPER and SILCOPER commands into the server and
2405 * Added silc_auth_verify and silc_auth_verify_data to verify
2406 the authentication directly from the authentication payload.
2407 It supports verifying both passphrase and public key based
2408 authentication. Affected file lib/silccore/silcauth.[ch].
2410 * Added `hash' field to the SilcIDListData structure. It is the
2411 hash negotiated in the SKE protocol. Affected file is
2414 * Slight redesigning of the SilcAuthPayload handling routines.
2415 Do not send SilcPKCS but SilcPublicKey as argument.
2417 * Implemented the public key authentication support to the
2418 serverconfig. The public key is loaded from the provided path
2419 and saved as authentication data to void * pointer. Thus,
2420 changed the unsigned char *auth_data to void *auth_data;
2422 * Fixed SHUTDOWN command to send the reply before the server
2423 is shutdown. :) Affected file silcd/command.c.
2425 * Fixed fatal bug in CONNECT command. The hostname was invalid
2426 memory and server crashed. Affected file silcd/command.c.
2428 * Fixed fatal bug in CLOSE command. The server_entry became
2429 invalid but was referenced later in the command. Affected file
2432 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Fixed fatal bug in failure packet handling. Server ignored
2435 the failure and thus crashed when it came.
2439 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2442 that the command may be executed only once in (about) 2 seconds.
2443 The old SILC_CF_LAG flag is same but allows command bursts up
2444 to five before limiting.
2446 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2447 server code. Various commands now includes the CF_LAG_STRICT
2448 flag to disallow any kind of miss-use of the command.
2450 * Fixed the silc_buffer_unformat to not to allocate any data
2451 if the length of the data is zero. It used to allocate the
2452 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2454 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Changed the format of AdminConnection configuration section
2457 in the server. Added username of the admin to the format.
2458 Affected files silcd/serverconfig.[ch].
2460 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2461 to return admin configuration data by host, username and/or
2464 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Implemented WHOWAS command to the server. Added the functions:
2468 silc_server_command_whowas_parse,
2469 silc_server_command_whowas_send_reply,
2470 silc_server_command_whowas_from_client and
2471 silc_server_command_whowas_from_server
2473 * Added <Client ID> argument to the WHOWAS command reply. Updated
2474 the protocol specs accordingly.
2476 * Implemented WHOWAS command and command_reply to the client
2479 Implemented the WHOWAS printing on the user interface.
2481 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Added new argument to the WHOWAS command reply, the real name.
2484 It is an optional argument. Updated the protocol specs.
2486 * Added SilcIDCacheDestructor callback that is registered when
2487 the SilcIDCache is allocated. The callback is called when
2488 an cache entry in the ID Cache expires, or is purged from the
2489 cache. Added into lib/silccore/idcache.[ch].
2491 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2492 to destruct the client entries when the cache entry expires.
2493 Other ID Cache's in server and in the client library ignores
2496 * If the ID Cache entry's `expire' field is zero then the entry
2497 never expires. Added boolean `expire' argument to the
2498 silc_idcache_add function in the lib/silccore/idcache.[ch].
2499 If it is TRUE the default expiry value is used.
2501 * Added silc_server_free_client_data_timeout that is registered
2502 when client disconnects. By default for 5 minutes we preserve
2503 the client entry for history - for WHOWAS command.
2505 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Added support to the server to enforce that commands are not
2508 executed more than once in 2 seconds. If server receives
2509 commands from client more frequently, timeout is registered
2510 to process the commands. Affected file silcd/command.c.
2511 Added new function silc_server_command_process_timeout.
2513 * Changed NICK_NOTIFY handling in client library to check that
2514 if the client's nickname was changed, so there is no need to
2515 resolve anything from the server.
2517 * Removed error printing from the WHOIS and IDENTIFY commands.
2518 If error occurs then it is ignored silently in the client library.
2519 The application, however, may map the received error to
2520 human readable error string. The application currently maps
2521 the NO_SUCH_NICKNAME error to string.
2523 * Made the command status message public to the application. Moved
2524 them from lib/silcclient/command_reply.c to
2525 lib/silcclient/command_reply.h. The application can map the
2526 received command status to the string with the
2527 silc_client_command_status_message function.
2529 * Added check to the server to check that client's ID is same
2530 as the Source ID in the packet the client sent. They must
2533 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Added dist-bzip hook to the Makefile.am to make bzip2
2536 compressed distributions.
2538 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Server now enforces the maximum length for the nickname and
2541 the channel as protocol specification dictates. 128 bytes for
2542 nickname and 256 bytes for channel name.
2544 * Moved the WHOIS printing to the application. The client libary
2545 does not print out the WHOIS information anymore, the application
2546 must do it. Renamed silc_client_command_reply_whois_print to
2547 the silc_client_command_reply_whois_save.
2549 The client's idle time is also sent to the application now, and
2550 the idle is shown on screen.
2552 * Added silc_client_command_reply_identify_save to save the
2553 received IDENTIFY entries.
2555 * Do not check for channel private keys in message sending and
2556 reception if the channel does not have the PRIVKEY mode set.
2557 Affected file lib/silclient/client_channel.c.
2559 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2562 just surfaced after chaning the JOIN procedure.
2564 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Added silc_client_get_clients_by_list to get client entries
2567 from Client ID list, that is returned for example by JOIN
2568 and USERS command replies. The application should use this
2569 function for example when JOIN command reply is received to
2570 resolve the clients already on the channel (library does not
2571 do that anymore as USERS command reply is not used in the JOIN
2572 procedure anymore). Affected files lib/silcclient/silcapi.h and
2573 lib/silcclient/idlist.c.
2575 * JOIN command reply and USERS command reply returns now SilcBuffer
2576 pointers instead of unsigned char pointers when returning
2577 the client list and mode list.
2579 * Added <Client ID> argument to the JOIN command reply, mainly
2580 for the server to identify for which client the command was
2581 originally sent. Updated protocol specs accordingly.
2583 * Added SilcDlist private_key pointer to the SilcChannelEntry
2584 in the client to support the channel private keys. Affected
2585 file is lib/silcclient/idlist.h.
2587 * Added SilcChannelPrivateKey argument to the function
2588 silc_client_send_channel_message so that application can choose
2589 to use specific private ke if it wants to. If it is not provided,
2590 the normal channel key is used, unless private keys are set.
2591 In this case the first (key that was added first) is used
2592 as the encryption key.
2594 * Implemented the support for channel private key handling.
2595 Implemented the following functions:
2597 silc_client_add_channel_private_key,
2598 silc_client_del_channel_private_keys,
2599 silc_client_del_channel_private_key,
2600 silc_client_list_channel_private_keys and
2601 silc_client_free_channel_private_keys
2603 Affected file lib/silcclient/client_channel.c.
2605 * Added the support for the private keys in the channel message
2606 sending and encryption and in the message reception and
2607 decryption. Affected funtions are
2608 silc_client_send_channel_message and silc_client_channel_message.
2610 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added SKE's key verify callback to the client library's
2613 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2615 * Removed the statement that server (or router) must send USERS
2616 command reply when joining to the channel so that the client
2617 knows who are on the channel. Instead, the client list and
2618 client's mode list is now sent in the JOIN command reply to the
2619 client who joined channel. This is better solution.
2621 * Added function silc_server_get_users_on_channel and function
2622 silc_server_save_users_on_channel to the silcd/server.[ch].
2624 * Removed function silc_server_command_send_users from the
2627 * Do not show topic on the client library anymore. The topic is
2628 sent in the command reply notify to the application and the
2629 application must show the topic now.
2631 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Added client searching by nickname hash into the IDENTIFY and
2634 WHOIS commands in the server as they were clearly missing from
2635 them. Affected file is silcd/command.c.
2637 * Fixed a bug in private message receiving in the client library.
2638 The remote ID was freed and it wasn't supposed, now it is
2641 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Minor fix to the channel payload; allocate the data area, as it
2644 needs to be of specific length.
2646 * If the key agreement port is zero then the operating
2647 system will define the bound port. Affected files are
2648 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2650 * Added new function silc_channel_payload_decrypt into the file
2651 lib/silccore/silcchannel.[ch].
2653 * Moved the channel message etc, check from silc_packet_decrypt
2654 to applications. The library calls now a generic
2655 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2656 when the packet is either normal or special. This was done to
2657 allow more wide range of checking that was not allowed when
2658 the code was in library. Now applications can do virtually any
2659 checks to the packet and return to the library the decision how
2660 the packet should be processed. Affected files are
2661 lib/silccore/silcpacket.[ch].
2663 Added silc_server_packet_decrypt_check to the server and
2664 silc_client_packet_decrypt_check to the client library.
2666 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2667 to send with specified source and destination information.
2669 * Channel message delivery between routers was broken after the
2670 channel key distribution was fixed earlier. The channel key
2671 was used be to distributed to other routers as well which is not
2672 allowed by the protocol. Now this is fixed and channel keys
2673 really are cell specific and the channel message delivery between
2674 routers comply with the protocol specification.
2676 * Fixed various commands in server to check also the global list
2677 for the channel entry and not just the local list. The affected
2678 file silcd/command.c.
2680 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Added assert()s to buffer formatting and unformatting routines
2683 to assert (if --enable-debug) when error occurs. Affected
2684 file: lib/silcutil/silcbuffmt.c.
2686 * Changed to auto-reconnect to check whether the remote host is
2687 router and register the re-connect timeout if it is. It used
2688 to check that whether we are normal server, but router must do
2689 auto-reconnect with another router as well. Affected file
2692 * Removed the [<key len>] option from CMODE command as the cipher
2693 name decides the key length, nowadays. See the defined ciphers
2694 from the protocol specification.
2696 * Added [<hmac>] option to the CMODE command to define the HMAC
2697 for the channel. Added SILC_CMODE_HMAC channel mode.
2699 * Added [<hmac>] option for the JOIN command so that user can
2700 select which HMAC is used to compute the MACs of the channel
2703 * Added Hmac field to the Channel Message Payload. The integrity
2704 of plaintext channel messages are now protected by computing
2705 MAC of the message and attaching the MAC to the payload. The
2706 MAC is encrypted. Now, it is clear that this causes some
2707 overhead to the size of the packet but rationale for this is that
2708 now the receiver can verify whether the channel message decrypted
2709 correctly and also when private keys are set for the channel the
2710 receiver can decrypt the packet with several keys and check from
2711 the MAC which key decrypted the message correctly.
2713 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2714 lib/silccrypt/silccipher.[ch].
2716 * Added silc_hash_len to return the digest length into the
2717 lib/silcrypt/silchash.[ch].
2719 * Rewrote parts of Silc Channel Payload interface in the
2720 lib/silccore/silcchannel.[ch]. The encode function now also
2721 encrypts the packet and parse function decrypts it.
2723 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Fixed a minor formatting bug in the SKE's key material processing.
2726 It actually might have processed the keys wrong way resulting
2729 * Redefined the mandatory HMAC algorithms and added new algorithms.
2730 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2731 and hmac-md5 truncated to 96 bits. The mandatory is now
2732 hmac-sha1-96. Rest are optional (including the one that used
2733 to be mandatory). Rationale for this is that the truncated HMAC
2734 length is sufficient from security point of view and can actually
2735 make the attack against the HMAC harder. Also, the truncated
2736 HMAC causes less overhead to the packets. See the RFC2104 for
2739 * Added new [hmac] configuration section. The SKE used to use
2740 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2741 is of course wrong. The official names that must be proposed in
2742 the SKE are the ones defined in the protocol specification
2743 (hmac-sha1-96 for example). The user can configure any hmac
2744 using any hash function configured in the [hash] section. At
2745 least, the mandatory must be configured.
2747 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2749 * Added HMAC list to the SKE proposal list. It has now both
2750 hash algorithm list and HMAC list. This makes the protocol
2751 incompatible with previous versions. The SKE now seems to work
2752 the way it is supposed to work, for the first time actually.
2754 * Defined plain Hash algorithms to the protocol specification.
2757 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Implemented support for key agreement packets into the server.
2760 Added functions silc_server_key_agreement and
2761 silc_server_send_key_agreement. Other than these functions,
2762 server has nothing to do with this packet.
2764 * Added support for private message key packets into the server.
2765 Added functions silc_server_private_message_key and
2766 silc_server_send_private_message_key.
2770 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2771 called in the protocol's final callback instead in the END
2772 protocol state. This makes a little more sense and in the same
2773 time in client we can use the same protocol routines for normal
2774 key exchange and to key agreement packet handling as well.
2776 * Added to both client's and server's KE protocol context the
2777 SilcSKEKeyMaterial pointer to save the key material. We will
2778 bring the key material to the protocol's final callback by doing
2779 this. The final callback must free the key material.
2781 * Added SKE's packet_send callback into client's KE protocol
2782 context so that the caller can choose what packet sending function
2783 is used. This way we can use different packet sending when
2784 doing normal SKE when doing key agreement packet handling (in
2785 the key agreement packet handling we do not want to encrypt
2788 * Implemented the responder side of the key agreement routines
2789 in the client. The client can now bind to specified port and
2790 accept incoming key negotiation. The key material is passed
2791 to the application after the protocol is over.
2793 * Implemented the processing of incoming Key Agreement packet
2794 in the client. Added function silc_client_key_agreement to
2797 * Implemented the intiator side of the key agreement routines
2798 in the client. The client can now initiate key agreement with
2799 another remote client. The key material is passed to the
2800 application after the protocol is over.
2802 * Created client_keyagr.c to include all the key agreement
2805 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2806 SILC_TASK_CALLBACK except that it is not static.
2808 * Created client_notify.c and moved the Notify packet handling
2809 from the client.[ch] into that file.
2811 * Created client_prvmsg.c and moved all private message and
2812 private message key routines from the client.[ch] into that file.
2814 * Create client_channel.c and moved all channel message and
2815 channel private key routines from the client.[ch] into that file.
2817 * Changed silc_client_get_client_by_id_resolve to resolve with
2818 WHOIS command instead of IDENTIFY command, in the file
2819 lib/silclient/idlist.c.
2821 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Implemented the SKE's responder side to the Client library.
2825 * When FAILURE is received to the protocol do not trust it
2826 blindly. Register a timeout to wait whether the remote closes
2827 the connection as it should do it, only after that process the
2828 actual failure. This was changed to both client and server.
2830 * Added client_internal.h to include some of the structures
2831 there instead of client.h in lib/silcclient/.
2833 * Added function silc_task_unregister_by_callback to unregister
2834 timeouts by the callback function.
2836 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Some "Incomplete WHOIS info" errors has been appearing on the
2839 log files. Took away the entry->userinfo check from WHOIS
2840 reply sending. The entry->userinfo is now " " if client did not
2841 provide one. I thought this was fixed earlier but something
2842 is wrong still. Let's see if the error still appears.
2844 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * Fixed a minor bug in the login when the channel key is
2847 re-generated in the server. It used to generate the key in
2848 wrong order and thus caused problems in the channel traffic.
2850 * Fixed a minor bug in channel key distsribution after
2851 KICK command. The key was not sent to the router even though
2854 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Added silc_ske_process_key_material_data as generic routine
2857 to process any key material as the SILC protocol dictates. The
2858 function is used by the actual SKE library but can be used by
2859 applications as well. This relates to the private message keys
2860 and the channel private keys since they must be processed the
2861 same way the normal SILC session keys. The protocol dictates
2862 this. Affected files: lib/silcske/silcske.[ch].
2864 Added also silc_ske_free_key_material to free the
2865 SilcSKEKeyMaterial structure.
2867 * Defined silc_cipher_set_key function to set the key for
2868 cipher without using the object's method function. The affected
2869 files: lib/silccrypt/silccipher.[ch].
2871 * Implemented silc silc_client_add_private_message_key,
2872 silc_client_add_private_message_key_ske,
2873 silc_client_del_private_message_key,
2874 silc_client_list_private_message_keys and
2875 silc_client_free_private_message_keys functions in the
2878 Added functions silc_client_send_private_message_key to send
2879 the Private Message Key payload and silc_client_private_message_key
2880 to handle incoming Private Message Key payload.
2882 * Added Cipher field to the Private Message Key payload to set
2883 the cipher to be used. If ignored, the default cipher defined
2884 in the SILC protocol (aes-256-cbc) is used.
2886 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Removed lib/silcclient/ops.h file.
2890 Redefined parts of the SILC Client Library API. Created new
2891 file silcapi.h that deprecates the ops.h file and defines the
2892 published Client Library API. Defined also private message key
2893 API and channel private key API into the file.
2895 This is the file that the application must include from the
2896 SILC Client Library. Other files need not be included by
2897 the application anymore.
2899 * Added new key_agreement client operation callback and also
2900 defined the Key Agreement library API for the application.
2902 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2905 is used by clients to request key negotiation between another
2906 client in the SILC network. If the negotiation is started it
2907 is performed using the SKE protocol. The result of the
2908 negotiation, the secret key material, can be used for example
2909 as private message key.
2911 Implemented the Key Agreement payload into the files
2912 lib/silccore/silauth.[ch].
2914 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Redefined ciphers for the SILC protocol. Added some new ciphers
2917 and defined the key lengths for the algorithms. Changed the
2918 code accordingly. The default key length is now 256 bits.
2920 * Fixed SKE key distribution function silc_ske_process_key_material
2921 when the key length is more than 128 bits. The default key
2922 length in SILC is now 256 bits.
2924 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2925 to indicate unsupported algorithm.
2927 * Renamed rijndael.c to aes.c and all functions as well.
2929 * Fixed a long standing channel key setting bug in client library.
2930 Weird that it has never surfaced before.
2932 * Fixed bug in channel deletion. If the entire channel is removed
2933 then it must also delete the references of the channel entry
2934 from the client's channel list as the client's channel entry and
2935 the channel's client entry share same memory.
2937 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * Implemented CONNECT and SHUTDOWN commands in the client.
2941 * Implemented CLOSE command to the client.
2943 * Added the function silc_idlist_find_server_by_name into the
2944 files silcd/idlist.[ch].
2946 Added the function silc_idlist_find_server_by_conn into the
2947 files silcd/idlist.[ch].
2949 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * DIE command was renamed to SHUTDOWN. Updated the both code
2954 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2955 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2957 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2960 * Added function silc_server_create_connection function to create
2961 connection to remote router. My server implementation actually
2962 does not allow router to connect to normal server (it expects
2963 that normal server always initiates the connection to the router)
2964 so the CONNECT command is only good for connecting to another
2967 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2970 or some other client was kicked from the channel.
2972 Implemented the handling of the notify type to both client
2975 Implemented silc_server_send_notify_kicked to send the KICKED
2976 notify. It is used to send it to the server's primary router.
2978 * Implemented the KICK command into server and client.
2980 * Added `query' argument to the silc_idlist_get_client function
2981 to indicate whether to query the client from server or not if
2984 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2985 to indicate that the client is not channel founder.
2989 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Removed the rng context from SilcPacketContext structure and
2992 changed that the packet routine uses the Global RNG API.
2994 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Added support for quit message that client can "leave" on the
2997 channel when it quits the SILC. It is ditributed inside the
2998 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3000 Added silc_server_free_client_data that will take the
3001 signoff message as argument.
3003 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3005 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Updated parts of the protocol specification to keep it up
3010 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3013 payloads in one packet.
3015 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3016 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3017 use now the new List flag.
3019 * Also deprecated the following packet types: REPLACE_ID,
3020 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3022 * Added list support for Notify packet in server.
3024 * Added silc_server_send_notify_channel_change to send the
3025 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3026 the silc_server_send_replace_id.
3028 * Added silc_server_send_notify_nick_change to send the
3029 NICK_CHANGE notify type. Deprecates the function
3030 silc_server_send_replace_id.
3032 * Added silc_server_send_notify_join to send the JOIN notify type.
3033 Deprecates the function silc_server_send_new_channel_user.
3035 * Added silc_server_send_notify_leave to send LEAVE notify type.
3036 Deprecates the function silc_server_send_remove_channel_user.
3038 * Added silc_server_send_notify_cmode and
3039 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3040 types. Deprecates the silc_server_send_set_mode function.
3042 * Added SERVER_SIGNOFF notify type to indicate that server has
3043 quit. This means that all clients on the channel from that
3044 server will drop. This can be also used when netsplit happens.
3046 Deprecated REMOVE_ID packet type since it is not needed anymore
3049 Added silc_server_send_notify_server_signoff to send the
3050 SERVER_SIGNOFF notify type. Deprecates the function
3051 silc_server_send_remove_id.
3053 Added also silc_server_send_notify_signoff to send the
3054 SIGNOFF notify type.
3056 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3057 SILC protocol from this day on. Changed the protocol
3058 specification as well.
3060 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3061 notify type. It is used between routers to notify about
3062 topic changes on a channel.
3064 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3067 * Partly updated the protocol specification to comply with the
3068 changes now made. It is still though a bit outdated.
3070 * The JOIN notify type now takes one extra argument <Channel ID>.
3071 The packet used to be destined to the channel but now the
3072 JOIN type may be sent as list thus it is impossible to
3073 destine it to any specific channel. By adding this argument
3074 it is again possible.
3076 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3078 * Added CREDITS file. The CHANGES and CREDITS file will appear
3079 in the distribution as well.
3081 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3084 types in the server's silcd/packet_receive.c.
3086 * Implemented CMODE and CUMODE to work in router environment.
3088 * Fixed minor encoding and decoding buglet from the
3089 lib/silccore/silcmode.c.
3091 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3094 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3096 * Changed all SilcConfigServer* and silc_config_server* to
3097 SilcServerConfig* and silc_server_config*, respectively.
3100 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Associated the ID (client or server ID) to the Authentication
3103 Payload to avoid any possibility of forging. Updated the
3104 protocol specification and the code accordingly.
3106 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * The RSA key length is now save to the RsaKey context in the
3109 key generation process in lib/silccrypt/rsa.c. The key length
3110 is now used to figure out the maximum size of the block allowed
3111 to be encrypted/signed.
3113 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3114 is equivalent to the silc_mp_mp2bin but does not allocate any
3117 * Changed silc_mp_mp2bin API to take length argument. If it is
3118 non-zero then the buffer is allocated that large. If zero, then
3119 the size is approximated using silc_mp_sizeinbase, which however
3122 * Created Global RNG API which is global RNG that application can
3123 initialize. After initializing, any routine anywhere in the
3124 code (including library) can use RNG without allocating a new
3125 RNG object. This was done to allow this sort of use of the
3126 RNG in code that has no chance to allocate RNG object. All
3127 applications currently allocate this and many routines in the
3128 library use this. Affected file lib/silccrypt/silcrng.[ch].
3130 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3131 it to use the Global RNG API.
3133 * Defined Authentication Payload into protocol specification that
3134 is used during SILC session to authenticate entities. It is
3135 used for example by client to authenticate itself to the server
3136 to obtain server operator privileges.
3138 Implemented this payload into the lib/silccore/silcauth.[ch].
3139 Implemented also routines for public key based authentication
3140 as the new protocol specification dictates.
3142 Moved definitions of different authentication methods from
3143 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3145 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3146 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3147 silc_pkcs_verify_with_hash functions into the file
3148 lib/silccrypt/silcpkcs.[ch].
3150 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * The client entry's userinfo pointer must be always valid.
3153 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3154 will fail since it requires the userinfo. Now, the userinfo
3155 is allocated as "" if actual userinfo does not exist. Actually,
3156 it must exist and it is totally Ok to drop client connections
3157 that does not announce the userinfo. However, we will make
3158 this workaround for now.
3160 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3161 to return the remote port by socket.
3163 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3166 SILC_SERVER_PENDING_EXEC and added an new macro
3167 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3168 data or when error occurs while processing the pending command.
3170 Added new argument `destructor' into silc_server_command_pending
3171 and to the SilcServerCommandPending object. This destructor is
3172 now called after calling the pending callback or if error occurs
3173 immediately. If error occurs the actual pending callback won't
3174 be called at all - only the destructor. The destructor may be
3175 NULL if destructor is not needed.
3177 All this applies for client library code as well. Similar
3178 changes were made there as well for the pending commands.
3180 In the client, the application must now allocate the
3181 SilcClientCommandContext with the silc_client_command_alloc
3184 * Added reference counter to the SilcServerCommandContext. Added
3185 function silc_server_command_alloc and silc_server_command_dup
3188 Same type of functions added to the client library for the same
3191 * Removed the cmd_ident from IDListData away since it is now
3192 global for all connections. It is the command identifier used
3193 in command sending and with pending commands. The affected file
3196 * Added reference counter to the SilcSocketConnection objecet to
3197 indicate the usage count of the object. The object won't be
3198 freed untill the reference counter hits zero. Currently only
3199 server uses this, and client ignores it. The client must be
3200 set to use this too later. The affected files are
3201 lib/silccore/silcsockconn.[ch]. Added also the function
3202 silc_socket_dup to increase the reference counter.
3204 This was mainly added because it is possible that the socket
3205 is removed underneath of pending command or other async
3206 operation. Now it won't be free'd and proper DISCONNECTING
3207 flags, etc. can be set to avoid sending data to connection that
3208 is not valid anymore.
3210 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3211 the connection. After that it sets SILC_SET_DISCONNECTED.
3212 It is, however, possible that the socket data is not still freed.
3213 The silc_server_packet_process now checks that data is not
3214 read or written to connection that is DISCONNECTED. The socket
3215 get's freed when the reference counter hits zero.
3217 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Changed the client operation API: channel_message operation's
3220 `sender' is now the client entry of the sender, not the nickname
3221 and the `channel' is the channel entry, not the channel name.
3223 In the private_message operation the `sender' is now also the
3224 client entry of the sender not the nickname.
3226 Affected file is lib/silcclient/ops.h and all applications
3227 using the client operations.
3229 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Moved the calling of ops->connect() from connect_to_server_final
3232 into receive_new_id functin since that is the point when the
3233 client is actually allowed to send traffic to network. The
3234 affected file is lib/silcclient/client.c.
3236 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3239 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3240 (if needs broadcasting) instead of broadcasting the packets one
3241 by one which would make a burst in the network traffic.
3243 * Added `broadcast' argument to the functions in silcd/server.[ch]
3244 silc_server_create_new_channel[_with_id] to indicate whether
3245 to send New Channel packet to primary router.
3247 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Added new function into the silcd/server.[ch] files:
3250 silc_server_create_new_channel_with_id to create new channel with
3251 already existing Channel ID.
3253 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3254 lib/silccore/silcpacket.h. This packet is used t send list of
3255 Set Mode payloads inside one packet. Server uses this to set
3256 the modes for the channels and clients on those channels, that it
3257 announced to the router when it connected to it. The protocol
3258 specification has been updated accordingly.
3260 * The silc_server_new_channel did not handle the packet coming
3261 from normal server as it normally does not send that. However,
3262 when it announces its channels it does send it. Implemented
3263 the support for that.
3265 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3266 into the file lib/silccore/id.h.
3268 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Fixed memory leaks in the functions silc_idlist_del_client,
3271 silc_idlist_del_channel and silc_idlist_del_server in the file
3272 silcd/idlist.c. All of those leaked like a sieve.
3274 * Fixed some small memory leaks in the client's function
3275 silc_client_notify_by_server.
3277 * Added functions into silcd/server.c: silc_server_announce_clients,
3278 silc_server_announce_channels and silc_server_announce_server.
3279 These functions are used by normal and router server to announce
3280 to its primary router about clients, channels and servers (when
3281 router) that we own. This is done after we've connected to the
3284 These functions effectively implements the following packet types:
3285 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3286 and SILC_PACKET_NEW_ID_LIST.
3288 * Added new functions into the silcd/packet_receive.[ch]:
3289 silc_server_new_id_list, silc_server_new_channel_list and
3290 silc_server_new_channel_user_list to handle the incoming
3291 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3293 * Added support of changing Channel ID in the function
3294 silc_server_replace_id. If the server that announces a channel
3295 to the router already exists in the router (with same name but
3296 with different Channel ID), router is responsible to send
3297 Replace ID packet to the server and force the server to change
3298 the Channel ID to the one router has.
3300 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3301 client that the Channel ID has been changed by the router. The
3302 normal server sends this to the client. Client must start using
3303 the new Channel ID as the channel's ID.
3305 Implemented handling of this new type into lib/silcclient/client.c
3306 into the function silc_client_notify_by_server.
3308 * Added new function silc_idlist_replace_channel_id into the files
3309 silcd/idlist.[ch] to replace the Channel ID.
3311 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Call silc_server_command_identify_check always when processing
3314 the IDENTIFY command in silcd/command.c
3316 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3319 send keepalive packets. The packet can be sent by clients,
3320 servers and routers.
3322 Added function silc_socket_set_heartbeat into the file
3323 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3324 If not set, the heartbeat is not performed. The actual
3325 heartbeat is implemented in the low level socket connection
3326 library. However, application is responsible of actually
3329 Added silc_server_send_heartbeat to send the actual heartbeat
3330 packet into silcd/packet_send.[ch]. Server now performs
3331 keepalive with all connections.
3333 * Added silc_task_get_first function into lib/silcutil/silctask.c
3334 to return the timeout task with shortest timeout. There was a bug
3335 in task unregistration that caused problems. TODO has been
3336 updated to include that task system must be rewritten.
3338 * The client library will now resolve the client information when
3339 receiving JOIN notify from server for client that we know but
3340 have incomplete information.
3342 * Rewrote parts of silc_server_remove_from_channels and
3343 silc_server_remove_from_one_channel as they did not remove the
3344 channel in some circumstances even though they should've.
3346 * Encryption problem encountered in server:
3348 The LEAVE command used to send the Channel Key packet to the
3349 router immediately after generating it. However, the code
3350 had earlier sent Remove Channel user packet but not immediately,
3351 ie. it was put to queue. The order of packets in the router
3352 was that Channel Key packet was first and Remove Channel User
3353 packet was second, even though they were encrypted in the
3354 reverse order. For this reason, MAC check failed. Now, this
3355 is fixed by not sending the Channel Key packet immediately but
3356 putting it to queue. However, this is more fundamental problem:
3357 packets that are in queue should actually not be encrypted
3358 because packets that are sent immediately gets encrypted
3359 actually with wrong IV (and thus MAC check fails). So, packets
3360 that are in queue should be encrypted when they are sent to
3361 the wire and not when they put to the queue.
3363 However, the problem is that the current system has not been
3364 designed to work that way. Instead, the packet is encrypted
3365 as soon as possible and left to the queue. The queue is then
3366 just purged into wire. There won't be any fixes for this
3367 any time soon. So, the current semantic for packet sending
3370 o If you send packet to remote host and do not force the send
3371 (the packet will be in queue) then all subsequent packets to the
3372 same remote host must also be put to the queue. Only after the
3373 queue has been purged is it safe again to force the packet
3376 o If you send all packets immediately then it safe to send
3377 any of subsequent packets through the queue, however, after
3378 the first packet is put to queue then any subsequent packets
3379 must also be put to the queue.
3381 Follow these rules and everything works fine.
3383 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added new function silc_server_remove_clients_by_server to
3386 remove all client entries from ID list when the server connection
3387 is lost. In this case it is also important to invalidate all
3388 client entires as they hold the invalid server entry. This
3389 fixes fatal bug when server has lost connection and will reconnect
3392 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Made some sanity checks to silc_server_daemonise like to check
3395 whether the requested user and group actually exists.
3397 * Added sanity check to SKE's silc_ske_responder_finish to check
3398 that the public and private key actually is valid.
3400 * Invalidate the client's nickname when receiving Replace ID
3401 packet and the Client ID is being replaced. This means that the
3402 server will query the nickname if someone needs it (client)
3405 * Sort the ID Cache in client library when the ID Cache data
3406 has changed (needs sorting).
3408 * Do not allow for SILC client to create several connections to
3409 several servers. The client does not support windows right now
3410 and generating multiple connections causes weird behaviour.
3412 Irssi-silc client does support windows and can handle several
3413 connections without problems, see: www.irssi.org and SILC plugin.
3415 * Fixed some places where client was added to the IDList. The
3416 rule of thumb is following (in order to get everything right):
3417 If the client is directly connected local client then the
3418 `connection' argument must be set and `router' argument must be
3419 NULL to silc_idlist_add_client function. If the client is not
3420 directly connected client then the `router' argument must
3421 bet set and the `connection' argument must be NULL to the
3422 silc_idlist_add_client function.
3424 * The funtion silc_server_packet_send_local_channel actually did
3425 not check whether the client was locally connected or not. It
3426 does that now. Fixed a bug related to LEAVE command.
3428 * Fixed Remove Channel User payload parsing bug in server's
3429 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3431 * The server's silc_server_save_channel_key now checks also the
3432 global ID list for the channel as it might not be in the local
3433 list. Fixed a bug related to LEAVE command.
3435 * Is this the end of the [<unknown>] buglet that has been lurking
3436 around for a long time? A little for loop fix in server's
3437 silc_server_command_whois_parse that is used by both IDENTIFY
3438 and WHOIS command. At least, this was a clear bug and a cause
3439 of one type of [<unknown>] buglet.
3441 * WHOIS and IDENTIFY commands call the function
3442 silc_server_command_[whois/identify]_check function even if
3443 we are not router server.
3445 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Added --with-gmp configuration option. If set the GMP
3448 is always compiled in the SILC source tree. If not set then
3449 it is checked whether the system has the GMP3 installed. If
3450 it has then the GMP won't be compiled (the system's headers
3451 and library is used), if it doesn't have it then the GMP is
3452 compiled in the SILC source tree.
3454 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Changed RSA private exponent generation to what PKCS #1
3457 suggests. We try to find the smallest possible d by doing
3458 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3459 not security fix but optimization.
3461 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Added new config entry [Identity] to fork the server and run
3464 it as specific user and group. A patch from Bostik.
3466 * Imported Dotconf configuration library into lib/dotconf.
3467 This will be used to create the SILC configuration files later.
3468 It will appear in the distsribution after this commit.
3470 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * A big code auditing weekend happening. Auditing code for
3473 obvious mistakes, bugs and errors. Also, removing any code
3476 Removed files for being obsolete:
3478 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3479 inline in the file lib/silcutil/silcbuffer.h)
3481 o lib/silcutil/silcbufutil.c (the header has inline versions)
3483 Changed code to fix possible error conditions:
3485 o The buffer formatting routines now check that the destination
3486 buffer really has enough space to add the data. This applies for
3487 both buffer formatting and unformatting
3488 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3489 unformatting was changed to accomodate following rules:
3490 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3491 sent to the function while XXX_*STRING will not allocate or copy
3492 the data into the buffer. Instead it sets the pointer from the
3493 buffer into the pointer sent as argument (XXX_*STRING used to
3494 require that the pointer must be allocated already). This change
3495 makes this whole thing a bit more consistent and more optimized
3496 (note that the data returned in the unformatting with XXX_*STRING
3497 must not be freed now). The routines return now -1 on error.
3499 o Tried to find all code that use buffer_format and buffer_unformat
3500 and added return value checking to prevent formatting and
3501 especially unformatting errors and possible subsequent fatal
3504 o Changed ske->x and ske->KEY to mallocated pointers in
3505 lib/silcske/silcske.h. Fixed possible data and memory leak.
3507 o Added return value checking to all *_parse* functions. Fixed
3508 many memory leaks as well.
3510 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3511 so that buffer overflows would not happen. All code now also
3512 checks the return value as it can fail.
3514 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Added reconnection support to server if the normal server looses
3517 its connection to the router (for example if router is rebooted).
3518 The server performs normal reconnection strategy implemented
3519 to the server. Affected file silcd/server.c.
3521 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3523 * Added new packet type SILC_PACKET_SET_MODE that is used to
3524 distribute the information about changed modes (for clients,
3525 channels and clients channel modes) to all routers in the
3526 network. Updated the protocol specification accordingly.
3528 Added functions into silcd/packet_send.c and
3529 silcd/packet_receive.c: silc_server_send_set_mode,
3530 silc_server_set_mode.
3532 Added new files silcmode.[ch] into lib/silccore that implements
3533 the encoding and decoding of Set Mode Payload. Added new type
3534 SilcSetModePayload. Moved the definitions of different modes
3535 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3537 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Oops, a little mistake in server's connection authentication
3540 protocol. The protocol is not ended with FAILURE but with
3541 SUCCESS if the authentication is Ok. :) Affected file is
3544 * Implemented NICK_CHANGE notify handling in server in the file
3545 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3546 the local clients on the channel. After the changing nickname
3547 in router environment snhould work and the [<unknown>] nickname
3548 should appear no more.
3550 The silc_server_replace_id function that receives the Replace ID
3551 payload now sends the NICK_CHANGE notify type also in the file
3552 silcd/packet_receive.c
3554 * Changed WHOIS and IDENTIFY command to support the maximum amount
3555 of arguments defined in protocol specs (3328 arguments). This
3556 fixed a bug that caused problems when there were more than three
3559 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Added extra parameter, command identifier, to the
3562 silc_client_send_command so that explicit command identifier
3565 Changed that ID list routines uses specific command identifier
3566 when sending WHOIS/IDENTIFY requests to the server so that they
3567 can be identified when the reply comes back.
3569 Affected files lib/silcclient/command.[ch],
3570 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3572 * Added `sender' argument to silc_server_packet_send_to_channel
3573 to indicaet the sender who originally sent the packet to us
3574 that we are now re-sending. Ignored if NULL. Affected file
3575 silcd/packet_send.[ch].
3577 * Added some server statistics support in silcd/server_internal.h
3578 SilcServerStatistics structure and around the server code. Also
3579 send some nice statistics information when client is connecting
3582 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Fixed channel ID decoding in server's JOIN command reply in
3585 silcd/command_reply.c
3587 * Fixed braodcasting of replace ID payload to not to send it if
3588 we are standalone server in silcd/packet_receive.c.
3590 * Fixed all channel message sending routines to not to send
3591 packets to clients that has router set, since they are routed
3592 separately in the same function earlier. Affects file
3593 silcd/packet_send.c and all channel packet sending functions.
3595 * In USERS reply, res_argv[i] are not allocated, the table
3596 is allocated. Thus changed that free the table, not its
3599 * In server's whois_check and identify_check if the client is
3600 locally connected do not send any WHOIS commands - they are not
3603 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed some minor bugs in client when sending WHOIS command. The
3606 arguments was in wrong order.
3608 * Removed statis function add_to_channel from server in
3609 silcd/command.c that was previously used with the joining but
3612 * Tested USERS command in router environment successfully with two
3613 routers, two servers and two clients.
3615 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Reorganized the USERS command and command reply in client library
3618 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3619 When the command is given by user we register a pending command
3620 callback that will reprocess the command after the reply has been
3621 received from the server. When reprocessing the packet we then
3622 display the information. Thus, the USERS information is displayed
3623 now in the command callback instead of in the command reply
3624 callback. The processing of the command is same as previously
3625 when server has sent the command reply in the JOINing process.
3627 * Added to USERS command in silcd/command_reply.c to join the client,
3628 we didn't use to know about, to the channel after we've created
3629 a client entry for it. Also, for clienet we did know already still
3630 check whether it is on the channel or not and add it if not.
3632 * Removed silc_server_command_join_notify as the function and its
3635 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Changed the client's pending command handling to the same as the
3638 server's pending command handling. It is also now possible to
3639 execute command reply functions from other command reply
3640 function as the function callbacks for commands and command
3641 replies are one and same. The pending commands are not static
3642 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3643 in client connection context. Thus, pending commands are server
3644 connection specific as it is convenient.
3646 Changed the function silc_client_command_pending and
3647 silc_client_command_pending_del and added new function
3648 silc_client_command_pending_check. Removed the
3649 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3652 * Added cmd_ident, current command identifier, to the client
3653 connection context in lib/silcclient/client.h to keep track on
3654 command identifiers used in command sending. Client's command reply
3655 function handling now supports the mandatory command identifiers.
3657 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3658 funtions in client to fully support pending command callbacks.
3660 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3661 as one of the arguments to the application in the command reply
3664 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3665 before first releasing SILC but came back. Now it is removed again
3666 and should come back nomore. The FORWARDED flag was used only
3667 by the JOINing procedure by forwarding the command packet to router.
3668 Now, the JOINing procedure has been changed to more generic (due
3669 to various router environment issues) and FORWARDED is not needed
3670 anymore for anything. The protocol specification is yet to be
3673 Now, removed silc_server_packet_forward from server and the flag
3674 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3676 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Renamed NAMES command to USERS command. The NAMES was named that
3679 due to historical reasons. Now it is renamed. Also, rewrote
3680 parts of the USERS command. The nickname list is not sent anymore
3681 by the server. Only Client ID and mode lists are sent in the USERS
3682 command. Changed this also to the protocol specification.
3684 The client now resolves the names and stuff after it receives
3685 the USERS list from the server when joining to the channel.
3687 * WHOIS and IDENTIFY commands has been changed to support multiple
3688 Client ID's per command. One can now search for multiple users
3689 in the network by sending only one WHOIS or IDENTIFY command.
3690 Changed the code and the protocol specifications.
3692 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3693 uses silc_server_command_whois_parse to parse the request. */
3695 * If normal server, do not parse the WHOIS and IDENTIFY requests
3696 before sending it to the router. Saves some time.
3698 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Fixed JOIN command on client library. Wrong number of arguments
3701 used to crash the client.
3703 * Added silc_server_channel_has_global function to check whether
3704 channel has global users or not.
3706 * Added silc_server_channel_has_local function to check whether channel
3707 has locally connected clients on the channel.
3709 * The silc_server_remove_from_one_channel now checks whether the
3710 channel has global users or not after given client was removed from
3711 the channel. It also checks whether the channel has local clients
3712 on the channel anymore. If it does not have then the channel entry
3713 is removed as it is not needed anymore.
3715 * The silc_server_notify now checks on JOIN notify whether the joining
3716 client is one of locally connected or global. If it is global then
3717 the channel has now global users on the channel and that is marked
3718 to the channel entry. Also, it now saves the global client to
3719 global list who is joining and JOINs it to the channel. This is
3720 for normal server, that is.
3722 Changed silc_server_send_notify_on_channel,
3723 silc_server_packet_relay_to_channel and
3724 silc_server_packet_send_to_channel check if we are normal server
3725 and client has router set (ie. global client) do not send the
3726 message to that client, as it is already routed to our router.
3728 * Implemented LEAVE notify type handling in silc_server_notify
3731 * Tested LEAVE command in router environment successfully. Tested
3732 with two routers, two servers and two clients.
3736 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3738 * Implemented SIGNOFF notify type handling in silc_server_notify
3741 * silc_server_remove_id now removes the client entry from all channels
3742 it has joined and thusly sends SIGNOFF notify type.
3744 * Rewrote the NAMES list generation in server by removing two excess
3745 loops. The lists are created now inside one loop.
3747 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * silc_server_remove_channel_user checks now also global list
3750 for channel and client.
3752 * silc_server_new_channel_user checks now both local and global
3753 list for channel and client. Fixed a bug in client id decoding.
3754 Used to decode wrong buffer.
3756 * silc_server_channel_message checks now both local and global
3757 list for channel entry.
3759 * Tested channel joining (hence JOIN) in router environment
3760 successfully. Tested with two routers, two servers and two
3763 * Tested channel message sending in router environment successfully.
3765 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Added silc_server_save_channel_key into server.[ch] to save the
3768 received channel key in Channel Key payload processing. It is
3769 also used in JOIN command reply handling.
3771 Equivalent function silc_client_save_channel_key added into
3772 client.[ch] into client library.
3774 * Changed JOIN command reply to send information whether the channel
3775 was created or not (is existing already) and the channel key
3776 payload. Changed protocol specs accordingly.
3778 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3779 the request was sent by ID and not by nickname. Crashed on
3782 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3785 now correctly save the received data.
3787 * silc_server_free_sock_user_data now notifies routers in the
3788 network about entities leaving the network.
3790 At the same time implemented functions silc_server_remove_id
3791 and silc_server_send_remove_id to receive and send REMOVE_ID
3792 packets. The packet is used to notify routers in the network
3793 about leaving entities. The ID removed will become invalid in
3796 * Added function silc_idlist_del_server into server. Removes and
3797 free's server entry from ID list.
3799 * silc_server_private_message function now checks, if we are router,
3800 that the destination ID really is valid ID, naturally.
3802 * In router when NEW_ID packet is received (for new client) the
3803 hash of the Client ID is saved in the ID Cache but the
3804 client->nickname is set to NULL, instead of putting the hash
3807 IDENTIFY command now also checks that client->nickname must be
3808 valid. If it is not if will request the data from the server who
3809 owns the client. Added new function
3810 silc_server_command_identify_check.
3812 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3813 to set the command to already allocated Command Payload.
3815 * Tested private message sending in router environment with two
3816 routers, two servers and two clients. Fixed minor bugs and now
3819 * Fixed segfault from client's NAMES command. Used to crash if
3822 * Forwarded packets must not be routed even if it is not destined
3823 to the receiver. Changed server code comply with this.
3825 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added `require_reverse_mapping' boolean value to ServerParams
3828 structure. If TRUE (not default) the server will require that
3829 the connecting host has fully qualified domain name.
3831 If the reverse mapping is not required and hostname could not be
3832 found the IP address is used as hostname.
3834 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Implemented version string checking to both client and server.
3837 The check is incomplete currently due to the abnormal version
3838 strings used in development version of SILC.
3840 * Changed all command functions in server to use the new
3843 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Changed char *data to unsigned char *data in ID Cache system to
3846 support binary data as ID Cache data. Changed code to support
3847 binary data in lib/silccore/idcache.c.
3849 * Renamed silc_server_packet_relay_command_reply to
3850 silc_server_command_reply as it is normal packet receiving
3851 function. Rewrote the function to accept command replys for
3852 servers and not only for clients.
3854 * Mark remote router always as registered server if we are connecting
3855 to it. Otherwise, commands sent by the router to us are ignored.
3857 * All ID List find routines now returns the ID Cache Entry pointer
3858 as well if requested.
3860 * WHOIS command works now in router environment, tested with two
3861 routers, two servers and two clients.
3863 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3864 in router environment (as it is almost equivalent to WHOIS) but
3865 hasn't been tested thoroughly. Added new functions:
3867 silc_server_command_identify_parse
3868 silc_server_command_identify_send_reply
3869 silc_server_command_identify_from_client
3870 silc_server_command_identify_from_server
3872 * Disabled route cache adding because adding two different ID's with
3873 same IP replaces the old cache entry thus giving wrong route.
3874 The entry->router->connection is always the fastest route anyway
3875 so route cache may not be needed. Of course, new routes maybe
3876 established after receiving the ID when the entry->router->connection
3877 might not be anymore the most optimal.
3879 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Add route cache for received ID for fast routing.
3883 * Added silc_server_packet_route to route received packet on router
3884 that is not destined to us.
3886 * Renamed silc_server_get_route to silc_server_route_get.
3888 * Added id_string and id_string_len fields into SilcServer to
3889 include encoded ServerID for fast comparing without excess
3890 encoding of the ID's.
3892 * Cleaned up WHOIS command on server side. Added following static
3895 silc_server_command_whois_parse
3896 silc_server_command_whois_check
3897 silc_server_command_whois_send_reply
3898 silc_server_command_whois_from_client
3899 silc_server_command_whois_from_server
3901 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3902 arguments in command replies. All command functions should be
3903 updated to use this macro.
3905 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Minor typo fixes on command reply handling on server.
3909 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Added silc_server_command_add_to_channel internal routine to add
3912 the client to the channel after router has created the channel and
3913 sent command reply to the server.
3915 * Added generic silc_server_send_command to send any command from
3918 * Use static buffer with ID rendering instead of duplicating data.
3920 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Fixed a channel user mode bug when joining to a channel server gave
3923 everybody channel founder rights, oops.
3925 * We mark ourselves as the router of the incoming server connection
3926 if we are router ourselves. This way we can check in some packet
3927 sending functions whether it is locally connected server. For
3928 incoming router connections we put NULL.
3930 * For router sending packets locally means now always sending the
3931 packet cell wide; to local clients and local servers. For normal
3932 server sending packet locally means sending it to only local
3935 * Fixed the JOIN command to really work in router environment. If the
3936 channel is created it is always created by the router. Router is
3937 also responsible of making the initial joining to the channel,
3938 sending JOIN notify to the sending server and distributing
3939 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3940 does not exist server doesn't do anything else but forward the
3941 command to the router which performs everything.
3943 * Added silc_server_send_channel_key function to send the Channel Key
3946 * Added silc_server_create_channel_key to create new channel key. The
3947 channel key is now re-generated everytime someone joins or leaves
3948 a channel, as protocol dictates. Note: channel->key_len is the
3951 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3954 packet_receive.[ch] to separate packet sending and receiving
3955 routines. The server.[ch] now includes everything else including
3956 actual packet processing (writing and reading data) and other
3959 Renamed silc_server_private_message_send_internal to
3960 silc_server_send_private_message. The routine is still though
3961 used only to relay private messages as server does not send
3962 private messages itself.
3964 Renamed silc_server_new_channel to silc_server_create_new_channel
3965 and added new function sicl_server_new_channel that handles the
3966 incoming New Channel packet. Added also new sending function
3967 silc_server_send_new_channel to send New Channel Payload.
3969 * Added new function silc_server_notify to process incoming notify
3970 packet to the server/router. Server may then relay the notify
3971 to clients if needed.
3973 * Added new function silc_server_new_channel_user to process incoming
3974 New Channel User packet. Router will redistribute the packet and
3975 send JOIN notify to its local clients and locally connected servers
3976 if needed. Normal server will send JOIN notify to its local client
3977 on same channel when received this packet. Added also corresponding
3978 sending function silc_server_send_new_channel_user to sent the
3981 * Added boolean route argument to send_notif_to_channel and
3982 packet_send_to_channel functions to attempt to route the packet
3983 if it is TRUE and send only locally if it is FALSE.
3985 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * silc_server_replace_id now broadcasts the received replace ID
3988 packet if it is not broadcast packet already. The router must
3989 broadcast to inform other routers about changed ID.
3991 * Added backpointer to server's router into SilcServer context in
3992 silcd/server_internal.h.
3994 * Fixed silc_server_packet_broadcast to send correct broadcast
3997 * The channel key is now distributed to the local client as soon
3998 as it is received from the router (in router environment) so that
3999 no other packet may be sent for the channel until client has
4002 * silc_server_remove_channel_user now broadcasts the received
4003 Remove Channel User packet if it is not broadcast packet already.
4004 The router must broadcast to inform other routers about removed
4007 * Added users field into SilcPacketContext that is a reference count
4008 of the context. One can increase the reference count by calling
4009 silc_packet_context_dup which is now changed to just increase the
4010 reference count instead of duplicating the data. The reference
4011 count is decresed by calling silc_packet_context_free that will
4012 free the data after the reference count hits zero.
4014 For now on the packet context and everything allocated into it
4015 (including the raw packet from network) must be freed by calling
4016 the new silc_packet_context_free function. Added also new function
4017 silc_packet_context_alloc that must be used now to allocate the
4018 context. This also means that if a routine is asynchronous from
4019 silc_[client/server]_packet_parse_type the packet context must
4020 be duplicated by calling silc_packet_context_dup. Otherwise it
4021 gets free'd after silc_[client/server]_packet_parse_type returns.
4022 Also, one must remember that if packet is duplicated then its
4023 reference count must be decresed by calling the free function as
4024 many times as it was duplicated.
4026 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4027 from both client and server.
4029 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Made joining to a channel working in router environment.
4033 * Cleaned up JOIN command on server side and create function
4034 silc_server_command_join_channel internal routine to make the
4037 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Changed silc_command_pending list to SilcDList. Also, added
4040 `ident' field to SilcServerCommandPending structure to identify
4041 the reply and to call correct callback.
4043 Added silc_server_command_pending_check function to replace the
4044 corresnponding macro. The silc_command_pending list is not
4047 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4048 to set identifier to previously allocated Command Payload. It
4049 is used to set identifier for command when resending Command
4052 * Added silc_command_payload_encode_payload to encode Command
4053 Payload buffer from SilcCommandPayload structure.
4055 * Added silc_argument_payload_encode_payload to encode Argument
4056 payload buffer from SilcArgumentPayload structure.
4058 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Changed WHOIS command to support router connection on server side.
4061 The whois request is always sent to router unless the server is
4062 standalone server. After server has received the reply from the
4063 router will it send the reply to the client.
4065 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4066 broadcast received broadcast packet. The function is used only
4067 by router. The broadcast packet is always sent to the router's
4070 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4071 render given ID to printable string, for log files for example.
4073 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Made basic router to router connections working. At least they
4076 can now connect to each other but nothing really works the way
4077 they are supposed - yet.
4079 * Added new initiator token to RouterConnection configuration
4080 file in silcd/serverconfig.[ch]. It is used to tell whether we
4081 are the initiator to the remote router or whether we'll expect
4082 the other end to connect.
4084 * Moved registering of listener task to silc_server_init, hence
4085 the server starts listenning as soon as it is run, even if it
4086 does not have connections to other routers. Let's see how well
4089 * Changed default connection retry timeouts for more suitable in
4092 * Removed cipher and such arguments from silc_idlist_add_client
4093 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4094 Added new function silc_idlist_add_data to add the keys and stuff
4097 * Added SilcIDListData structure and added it to SilcClientEntry
4098 and SilcServerEntry as their first field in the structure. This
4099 way we can explicitly cast the ID entries to the SilcIDListData
4100 structure and get common data for the entries. In past, we had
4101 to first check what type of connection it is and then cast it to
4102 correct ID entry type. Now, we can directly cast the opaque
4103 pointer to the SilcIDListData (no matter what ID entry it actually
4104 is) and get the data needed.
4106 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4109 in some circumstances even if threre were timeout tasks, though not
4110 IO tasks, but tasks anyway. Now fixed.
4112 * Defined SilcServerConnection structure to hold connection specific
4113 stuff about directly connected servers and routers. The definition
4114 is currently in silcd/server_internal.h. I thought about having
4115 a bit more important role fro this struct but for now it is used
4116 only when connecting to other server (or router actually).
4118 * Added connecting retry support in server when connecting to
4119 router(s). The retry feature implement exponential backoff
4120 algorithm. Also, added SilcServerParams structure to hold default
4121 parameters for server. For now, it include these retry settings
4122 and are hard coded. After server is moded to be as Silc Server
4123 Library this structure will be more important.
4125 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Changed client librarys channel->clients table to SilcList and
4128 changed code accordingly.
4130 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Changed client's channel table to SilcList and changed code
4133 accordingly. Also changed SilcChannelClientEntry to include back-
4134 pointer to the channel so that client entry can use that structure
4135 as list as well and we have fast cross-reference to the channel.
4136 This change dramatically decreased the complexity of channel
4137 handling with client entry and vice versa (removed one extra
4138 loop when searching for channel entry from many functions).
4140 * Changed server->sim from table to SilcDList and changed code
4143 * NAMES command can now be used from user interface. It will show
4144 the user list on the channel, neatly.
4146 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4147 Code now saves realname of the user if it becomes available.
4149 * Renamed configure.in to configure.in.pre and made ./prepare
4150 script to automatically add correct version string to
4151 configure.in which it creates from configure.in.pre.
4153 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * NAMES command reply now shows users mode with the nickname when
4158 * Moved silc_client_ch[u]mode[_char] functions from
4159 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4160 place sucks, they are utility functions and should be in some
4163 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4165 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4168 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Added TRQ (efficient deque and list library) into lib/trq. This is
4173 a very good list library that is currently used in the SILC. Defined
4174 SilcList API over the library because I didn't like the API very
4175 much. See lib/trq/silclist.h for the API and examples of how to
4176 use the API. Fixed various places in the code to use the new
4177 SilcList API. The SilcList is meant for lists that has a structure
4178 already defined as a list. It is not suitable to add just some
4179 context to the list (in TRQ, the context is the list actually).
4181 So, I defined SilcDList that can be used for the purpose where
4182 predefined list structure does not exit. This can be used as
4183 such list. Now some context just can be added to the SilcDList.
4184 Currently this list is not used in the SILC just yet, though there
4185 are a lot places where this can replace dynamically allocated
4186 tables and I will fix these places, later, to use SilcDList.
4187 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4188 and use TRQ internally).
4190 Also fixed some annoying warning messages that the original TRQ
4191 code generated. Also minor changes to TRQ's Makefile.in.
4193 * Added support for querying by Client ID to both WHOIS and
4194 IDENTIFY commands into server, as required by the protocol.
4196 * Removed method function pointers from SilcBuffer structure. They
4197 weren't used to anything and just increased the context size for
4198 no good reason. This change also made silc_buffer_alloc and
4199 silc_buffer_free functions inline functions.
4201 * Disabled command flooding detection support until it's fixed so
4202 that it accepts commands in but does not execute them more than once
4205 * Added silc_net_localhost(), to return local hostname, into
4206 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4207 that must be initialized before calling silc_client_init.
4209 * Added new function: silc_server_send_notify_on_channels to send
4210 notify messages to all channels client has joined. It is assured
4211 that the message is sent only once per client.
4213 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4214 lib/silcutil/silcutil.[ch] as silc_format function. The new
4215 function is generic and is used by server as well, not only by
4216 the logging routines.
4218 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4219 the provided version string was not acceptable. Added new function:
4220 silc_ske_check_version into lib/silcske/silcske.h. The function
4221 must be implemented by the application (client or server) and it
4222 does not reside in the SKE library. The function checks the version
4223 string remote end sent.
4225 * Added back pointers (to opaque context and to SilcSocketConnection)
4226 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4228 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4229 duplicate packet context structure.
4231 * Changed `notify' client operation to send same arguments as client
4232 receives from server except for ID's. ID's are mapped to correct
4233 ID entry and that is returned. Also, if channel entry is not sent
4234 by server but the notify is for channel the channel entry is sent
4235 to application (otherwise application doesn't know that it is for
4236 channel (library gets it from packet's Destination ID)).
4238 * Added silc_client_remove_from_channels into client library to
4239 remove a client from all channels it has joined to. Used when
4240 received SIGNOFF notify from server. Added also new function
4241 silc_client_replace_from_channels to replace old ID entry with
4242 new ID entry on all channels. Used when received NICK_CHANGE
4245 * Fixed ID Cache list handling in silc_idlist_get_client in
4246 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4247 to get (or query) client by ID.
4249 * Updated TODO list.
4251 * Added connection authentication status message defined by the
4252 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4253 support for these into the code in client and server side.
4255 * Added generic function silc_client_send_command to send any command
4256 with variable argument list. Application should use this function
4257 to send commands if the command functions provided by the library
4258 does not suite for the application's user interface needs.
4260 * Added new `failure' client operation. Application is notified about
4261 received failure packet if client is executing a protocol. In this
4262 case the protocol's execution has failed.
4264 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4265 is required by the protocol.
4267 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4268 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4271 * Added status flag to SilcSKE object to indicate realtime status
4272 of the SKE protocol.
4274 * Application receives now exactly same command reply arguments as
4275 the library receives from server. However, if ID is received the
4276 corresponding ID entry is returned to the application (eg. Client
4277 ID is mapped to correct SilcClientEntry entry and that is returned).
4278 Changed command_reply client operation due to this change.
4280 * Changed all ID's in commands and in command replys as ID Payloads.
4281 Change affected both client and server side codes.
4283 All ID's sent in SILC network (with execption of ID's in SILC
4284 Packet header) are sent in ID Payload to support variable length
4287 * Server now notifies nick changes and notifies all clients on
4288 the channels about the new nickname (about the new Client ID,
4291 * Implemented CMODE command to change channel modes. Supports all
4292 channel modes defined by the protocol specs except ban and invite
4293 lists. (Also, private channel key mode is supported but support for
4294 setting private channel key in client is missing, thus, this mode
4295 has no effect on client side (except that server requires that the
4296 client uses private channel key and normal channel traffic does not
4299 Also, invite mode works per se, but INVITE command does not work
4300 yet correctly, so you can set channel as invite only channel but
4301 inviting clients to the channel does not work (it is yet to be
4302 thought what's the best way to do it).
4304 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4305 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4306 Implemented CUMODE command to change user's mode on the channel.
4307 Supports all modes defined by the protocol specs.
4309 * Added NAMES command reply to return users modes on the channel.
4311 * Removed unnecessary and slow ciphers from lib/silccrypt.
4313 * Set SO_KEEPALIVE option to connection sockets by default.
4315 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4317 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4318 redefined the Notify Payload into protocol specs.
4320 * Added silc_id_payload_parse_id to get ID directly from raw
4323 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4326 accept searching by Client ID as well.
4328 * Added support for LEAVE and SIGNOFF notify types in client library.
4330 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4331 to parse ID Payload from raw data.
4333 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Added flags parameter into silc_ske_assemble_security_properties
4336 function in lib/silcske/silcske.[ch].
4338 * Changed notify client operation to fit better for notify messages
4339 sent by server. The notify payload received from server is now
4340 passed to the application (after parsing it to SilcNotifyPayload).
4341 It is application's responsibility to retrieve the arguments
4342 from the payload and show the message the way it wants. The message
4343 sent by server is implementation specific.
4345 * Changed public keys to comply with the protocol specification.
4346 Old public keys are not supported anymore and are not compatible.
4348 * Removed nickname from Channel Payload as the latest draft removed
4349 it. The client must resolve the nickname from the NAMES command
4350 reply received when it joined the channel.
4352 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4354 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Fixed some errors in protocol specification drafts.
4358 * Created lib/silccore/silcnotify.c to implement Notify Payload
4359 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4360 generic payloads described by protocol specifications. The file
4361 includes implementations for ID Payload and Argument Payload.
4363 * Changed Command Payload implementation to use the new Argument
4364 Payload. Changed command_xxxx_payload to command_payload_xxxx
4365 to comply with SILC coding conventions.
4367 * Added suppport for Argument Payload handling in Notify Payload
4368 implementation as protocol requires it. Added the new support
4369 into server and client lib as well.
4371 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added support for multiple nicknames on same channel. [n] is
4374 added locally to the nickname if there are more than one same
4375 nicknames on the channel.
4377 * Server now sends all nicknames that matched WHOIS request.
4378 Client also shows the list received from server.
4380 * Added TOPIC command to client side. User can now set and show
4381 current topic on channel.
4383 * Added MOTD command to client and server. Also, server sends the
4384 motd when client connects to the server.
4386 * Changed version strings to comply ISO 8601.
4388 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Fixed protocol error handling in client library. It should now
4391 cope even if the SKE fails for some reason.
4393 * Made new protocol specification drafts for submitting to IETF.
4395 * Implemented TOPIC command to server in silcd/command.c.
4397 * Added two new notify types into lib/silccore/silcnotify.h:
4398 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4399 notify nickname change and topic setting/change on a channel.
4401 * API change of command_reply operation in client library. The
4402 application gets now the status type received from server as well.
4404 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4408 * Cras fixed and optimized the packet handling even further and
4409 it should work now. Minor change to the prototype of function
4410 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4412 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Added new function into lib/silcutil/silcschedule.[ch]:
4415 silc_schedule_with_fd to select() a specified fd. The function
4416 returns after timeout expires or data arrives or goes. The
4417 function is used by packet routines to wait that all data is
4418 received from network.
4420 * Fixed data reading from network in lib/silccore/silcpacket.c.
4421 The code now assures that all data is read from the fd and then
4422 continues packet processing. This was a bug fix since the code
4423 used to drop some data in some circumstances.
4425 * Added new function into lib/silcclient/client.[ch]:
4426 silc_client_start_key_exchange to start key exchange after
4427 connection has been established to server. The code internally
4428 now uses this funtion but its main purpose was to provide it
4429 for applications that perform their own connecting. After
4430 application has created a connection it merely calls this
4431 function to start the key exchange between client and server.
4432 The library takes care of everything else after that.
4434 Updated also lib/silcclient/README to explain the usage of
4437 * Do not send to application information that connection has
4438 been established. Application gets notified it by connect
4441 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Applied cras's patch to add silc_schedule_one function. The
4444 function runs scheduler once and returns.
4446 * Fixed the scheduler after cras messed it up. The timeout
4447 handling works now as it's supposed to work.
4449 * Added into lib/silccore/ silcnotify.h to include notify
4450 message types support. Changed silc_server_send_notify*
4451 functions, in server.[ch], to support those new notify types.
4452 Added the support for the notify types into client library,
4453 as well. Added new notify client operation into ops.h in
4456 * Changed silc_server_packet_send_to_channel to send normal
4457 packets instead of just channel message packets. The function
4458 is now used to send the notify packets to channels. It is not
4459 used to send channel message packets anymore, as server never
4462 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4463 va_arg()s as it seems to require it nowadays. I guess, if SILC
4464 is compiled with older va_arg() the new code should work anyway.
4466 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Splitted core library. Core library (lib/silccore) includes
4469 now only SILC protocol specific core (and common) components.
4470 Created new utility library (lib/silcutil) that includes more
4471 generic purpose stuff. The stuff for util library was taken
4472 from the old core library. This was minor and easy split.
4474 * Created SILC Client Library (lib/silcclient) that includes
4475 implementation of the SILC client without user interface. This
4476 was major move from silc/ directory. The code has been changed
4477 so that it is transparent towards the user interface. The
4478 silc/ directory includes now the same user interface as before
4479 and it uses the new client library. Read lib/silcclient/README.
4480 Basicly, the client library performs everything else related
4481 to SILC except user interface handling. Also, configuration
4482 files are considered to be part of user interface and library
4483 does not handle them.
4485 This change also changed a lot of structures, function naming etc.
4486 Most important change was that SilcClientWindow object was
4487 renamed to SilcClientConnection in the client library. Created
4488 also new file lib/silcclient/ops.h. Also added new files
4489 silc/local_command.[ch] and silc/client_ops.[ch].
4491 All these changes were made to make it easier for user interface
4492 designers to create what ever user interface for the SILC client
4495 It is also expected that the server will be moved to lib
4496 directory as well and SILC Server Library will be created;
4497 sometimes in the future.
4499 * Removed Local commands from lib/silccore/silccommand.h as
4500 they are application specific and new client library does not
4501 handle any of those anymore.
4503 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4504 old client implementation in silc/.
4506 * Added support for callback functions in SILC_LOG_* macros.
4507 Application can now set its own callbacks that will be called
4508 instead of using the default functions that will always print
4509 the debug messages to stderr (or stdout). Also, debugging can
4510 now be disabled by setting silc_debug to FALSE and re-enabled by
4511 setting it to TRUE. Note, that logging will still work even
4512 if debugging is disabled.
4514 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4515 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4516 silc_log_reset_debug_callbacks.
4518 * To enable debugging in silc client one must give now -d
4519 option on command line.
4521 * Changed silc_schedule_init to automatically allocate task queues
4522 if they are not allocated before calling it.
4524 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added GMP 3.1 into math library.
4528 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4531 a channel in SILC network. The packet is used by servers and
4532 routers to notify other routers that user has left a channel.
4533 This little feature was missing until now. Added the feature
4534 to protocol specification as well.
4536 Added functions: silc_server_send_remove_channel_user and
4537 silc_server_remove_channel_user into server.[ch].
4539 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4540 lib/silccore/silcpacket.h. However, they are not implemented
4543 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Fixed joining to a channel and sending channel messages
4546 between server and router. The channel message sending should
4547 now work inside a cell.
4549 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Fixed the private message sending between server and router.
4552 The private message sending should now work inside a cell.
4554 * Added silc_server_replace_id into server.[ch] to replace
4555 existing ID in the SILC network.
4557 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4558 and silc_idlist_replace_server_id into idlist.[ch] in server.
4560 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Fixed the server to server connections. Server can again now
4563 connect to router. Router to router connections probably does
4566 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added dynamic protocol registering support. Now protocols can
4569 registered and unregistered on the fly. Patch by cras.
4571 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Added lib/contrib directory to hold routines that some platforms
4574 don't have but are needed by SILC.
4576 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4577 into lin/contrib to provide getopt() and getopt_long() for
4578 those who don't have it.
4580 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Added AWAY command to client. When away message is set and
4583 client receives a private message packet the client automatically
4584 replies to the sender with the away message.
4586 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4587 bug seemed to be the cause of recent problems when compiling
4590 * Added version detection support to SKE protocol specification
4591 and added the new changes to the SKE implementation as well.
4592 There were other minor changes in the SKE protocol as well.
4594 Many changes in lib/silcske/silcske.[ch] and in
4595 lib/silcske/payload.[ch].
4597 * Added ^U functionality, clear input line. Patch from cras.
4599 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Mainly small bugfixes on core library. Fixed some debugging
4602 logging and buffer overflow in silclog.c.
4604 * Updated config.sub and config.guess on the distribution tree.
4606 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Added command lagging support in server. Client may execute
4609 commands now only once in two seconds.
4611 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Optimized packet reception. MAC computation and checking is now
4614 also more optimized. A lot previously duplicated code is now
4615 used as generic by both client and server.
4617 * Fixed key pair generation in clientutil.c
4619 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Added into lib/silccore/silcbufutil.[ch] new function;
4622 silc_buffer_realloc.
4624 * Moved generic packet sending/encryption functions to
4625 lib/silccore/silcpacket.[ch] from client and server. Some
4626 rewriting of the functions.
4628 * Moved all generic packet reception/decryption functions to
4629 lib/silccore/silcpacket.[ch] from client and server. The
4630 packet processing is now much cleaner in both client and server.
4631 These were major changes in both client and server.
4633 * Created many common functions in server to do packet sending.
4634 Previously code were duplicated a lot, this has been removed
4637 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Rewrote major parts of the ID cache system. Don't know
4640 whether it is better now or not but at least the API is more
4643 * Major rewrite on ID cache stuff on client because of the ID
4644 cache API changes. Added idlist.c to client.
4646 * Also major rewrite on ID cache stuff on server as well.
4647 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4648 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4649 in hand, instead they are all put into the ID cache system now.
4650 All server_idlist_* routines uses ID cache now instead of
4651 traversing its own lists (those lists does not exist anymore).
4652 SilcIDList though still exists. Also, SilcXXXEntry's are
4655 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Finally made the SKE implementation compliant to the protocol
4658 specification. All mp integers are now binary encoded as
4659 opposed being HEX encoded.
4661 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4664 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4665 functions: silc_[encode/decode]_pem. Also added function
4666 silc_encode_pem_file to PEM encode with newlines ('\n') for
4669 * SILC public keys are now encoded either PEM or binary. Same
4670 option is for private keys as well. By default private keys
4671 are binary encoded and public keys PEM encoded. Silly HEX
4672 encoding were removed.
4674 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4675 function to create fingerprints.
4677 * Fixed a bug in SHA1; does not change the original data anymore.
4679 * Partly implemented INFO command on client and server side.
4680 Fixed CLEAR command. Changes to SERVER command; show current
4681 server(s) when giving command without arguments. Added
4682 VERSION command to client.
4684 * Added check to server that unregistered connections cannot
4685 execute commands (unless it is specificly allowed).
4687 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Fixed screen refresh.
4691 * Fixed channel joining bug from client. On some circumstances
4692 client tried to join to a channel it had already joined.
4694 * Added public key verification process into client's protocol.c.
4695 The client now verifies the public key from user and saves
4696 it into ~./silc/serverkeys/ directory.
4698 Added into: clientutil.[ch]: silc_client_verify_server_key.
4700 * Changed SKE protocol's silc_ske_initiator_finish function
4701 to accept callback function that verifies the received public
4702 key. Removed old silc_ske_verify_public_key function.
4704 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4707 silc_pkcs_private_key[_data]_set.
4709 * Made the password and public authentication more cleaner in
4710 server's protocol.c.
4712 * Removed historic and obsolete protocol `channel_auth' from
4713 both client and server.
4715 * Removed wrong way of sending command status messages from
4716 server to client in server's command.c. The old way violated
4717 protocol specification.
4719 Changes to silccore/silccommand.[ch]: removed
4720 silc_command_encode_status_payload -> not needed anymore,
4721 changed silc_command_encode_payload_va to accept extra
4722 argument on variable argument list. The argument type must
4723 now be provided to the function. Also, added new function:
4724 silc_command_encode_reply_payload_va which is same as
4725 normal command_encode_payload_va except command status type
4726 is provided as extra argument.
4728 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Added ~./silc directory handling. The directory includes the
4731 public and private keys for the client.
4733 Added silc_client_check_silc_dir, silc_client_create_identifier
4734 and silc_client_load_keys.
4736 * Implemented SILC protocol compliant public key. Added public
4737 and private key saving to and loading from files.
4739 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4740 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4741 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4742 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4743 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4745 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4746 silc_pkcs_load_[public/private]_key.
4748 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Added silc_server_get_route (route.[ch]) to get connection
4751 data for the fastest route for given ID.
4753 * Implemented INVITE command on client and server. The command
4754 were re-defined in the SILC Protocol Specification and the
4755 implementation now complies with the specification.
4757 * Implemented PING command on client and server.
4759 * Implemented NAMES command on client and server. The server side
4760 supports currently only normal server not router server yet.
4761 Some changes to NAMES definition in SILC protocol specification.
4763 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Implemented LEAVE command on client and server.
4767 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4768 again. This change was made to the protocol as well. Server
4769 should not violate the protocol specification anymore.
4771 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4774 was tested. SOCKS4 was not but should work anyway.
