1 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Changed the key material distribution function in case when
4 the hash output is too short. The data is now concatenated
5 a bit differently than it used to. Made the change to the
6 SKE protocol specification.
8 * Submitted new drafts to the IETF.
10 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Fixed a minor bug in SKE that might cause some problem on
13 some platforms. Affected file lib/silcske/silcske.c.
15 * Added the cookie checking for initiator in the SKE. It checks
16 that the responder returns the sent cookie unmodified. The
17 affected file is lib/silcske/silcske.c. Added new SKE
18 error type INVALID_COOKIE that can be sent during the
19 negotiation. Fixed some memory leaks as well.
21 * Added the "invalid cookie" error message to Irssi SILC client's
24 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
26 * Added `task_max' field to the SilcClientParams to indicate
27 the maximum tasks the scheduler can handle. If set to zero,
28 default values are used. Affected file lib/silcclient/silcapi.h.
30 * Fixed memory leaks in silc_client_close_connection. Affected
31 file lib/silcclient/client.c.
33 * Added silc_client_del_client_entry to client library to free
34 all memory of given client entry. Affected file is
35 lib/silcclient/idlist.[ch].
37 * Added new functions silc_client_del_channel and
38 silc_client_del_server to delete channel and server entries.
39 Affected file lib/silcclient/[silcapi.h/idlist.c].
41 * Removed silc_client_del_client_by_id from silcapi.h.
43 * Fixed the INFO command to return the server's own info
44 correctly when querying by Server ID. Affected file is
47 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
49 * Removed the non-blocking settings in WIN32 code in the
50 silc_sock_[read/write] and added SleepEx instead. Affected
51 file lib/silcutil/win32/silcwin32sockconn.c. The availability
52 of input data is now checked with FIONREAD and ioctlsocket.
54 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Call silc_schedule_task_del_by_context in the
57 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
58 Affected file lib/silccore/silcprotocol.c.
60 * Call silc_protocol_cancel for active protocols in the
61 silc_server_close_connection if the funtion
62 silc_server_free_sock_user_data has not been called.
63 Affected file silcd/server.c.
65 * Generic tasks cannot be deleted using the del_by_fd
66 task deleting function since generic tasks does not match
67 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
69 * Added a notion to SILCOPER help file that the SILCOPER works
70 only on router server, not on normal server.
72 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
74 * Added for WIN32 support for the new scheduler as well.
75 Affected file lib/silcutil/win32/silcwin32schedule.c.
77 * Fixed the SHA1 implementation to work on various platforms.
79 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
81 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
82 API. It is part of the scheduler now. Everything else is
83 as previously but some functions has changed their names.
84 Checkout the lib/silcutil/silcschedule.h for the interface.
85 Updated all applications to use the new interface. Affected
86 files are lib/silcutil/silcschedule.[ch].
88 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
90 * Found a bug in the SKE implementation. The HASH value,
91 specified by the protocol, was not computed correctly. The
92 public key of the responder was not added to the computation
93 even though it is mandatory. Affected file lib/silcske/silcske.c.
94 This unfortunately causes incompatibilities with older
97 * Added WIN32 specific network init and uninit functions:
98 silc_net_win32_init and silc_net_win32_uninit to init and uninit
99 the Winsock2. Affected file lib/silcutil/silcnet.h and
100 lib/silcutil/win32/silcwin32net.c.
102 * Set the socket always to nonblocking mode on WIN32 after
103 reading data or writing data. Affected file is
104 lib/silcutil/win32/silcwin32sockconn.c.
106 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
108 * Fixed various compilation problems under WIN32. Affected
109 files lib/silcutil/win32/silcwin32thread.c and
110 lib/silcutil/win32/silcwin32schedule.c.
112 * Removed all _internal.h #includes from public header
113 files. Internal headers must never be included from
116 Removed also the lib/silcske/payload_internal.h file.
118 * All include files that may be needed (public and some others
119 included by the public headers) by application developers are
120 now copied to the ./includes directory. It does not copy any
121 internal headers. Affected file Makefile.defines.pre and all
122 Makefile.am's under lib/ and subdirs.
124 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Do not change the ~/.silc directory's permissions automatically.
127 Affected file irssi/src/silc/core/clientutil.c.
129 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
131 * Do not cancel the protocol in silc_server_close_connection
132 it might cause recursion. Now cancelled in the function
133 silc_server_free_sock_user_data. Affected file silcd/server.c.
135 * Fixed the silc_server_remove_clients_by_server to regenerate
136 the channel keys correctly finally. Added also new function
137 silc_server_remove_clients_channels to actually do it.
138 Affected file silcd/server.c.
140 * Fixed the silc_server_new_channel to not crash by giving
141 wrong router to the new channel. Affected file is
142 silcd/packet_receive.c.
144 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
146 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
147 which is given as argument to the silc_client_alloc now.
148 It can be used to configure the client and set various parameters
149 that affect the function of the client.
151 * The USERS command in server did not check whether the channel
152 is private or secret. Affected file silcd/command.c.
154 * Added new argument to the USERS command in protocol specification.
155 The USERS command now can take the channel name as argument
156 as well. Added support for this in client and server and
157 updated the protocol specs.
159 * Completed the GETKEY command in client. It can be now used
160 to fetch also servers public key not only some clients.
161 Affected files lib/silcclient/command[_reply].c.
163 * Added silc_client_get_server to return server entry by the
164 server name. Affected files lib/silcclient/silcapi.h and
167 * Redefined the IDENTIFY command in protocol specification to be
168 more generic. It now can be used to query information about
169 any entity in the SILC Network, including clients, servers and
170 channels. The query may be based either the entity's name
171 or the ID. Added support for this in both client and server.
173 Affected files silcd/command.c and lib/silcclient/command.c
176 * Optimized the WHOIS and WHOWAS commands in the server. Removed
177 the _from_client and _from_server functions. Affected file
180 * Added silc_client_get_channel_by_id_resolve to the file
181 lib/silcclient/silcapi.h to resolve channel information by
182 its ID. Added also silc_client_get_channel_by_id that
183 does not resolve it from the server.
185 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
187 * Added SilcServerEntry context into the client library
188 to represent one server. The INFO command now allocates
189 these to save the resolved server info. For now on the
190 client library will also keep information about servers,
191 connected and resolved with INFO.
193 The INFO command now allocates the SilcServerEntry context
194 and saves the server info there. The COMMAND_REPLY in
195 the INFO now returns the parameters to application in
196 same order as defined in the protocol specification.
198 The entries are cached in the client->server_cache.
200 * The INFO command is now issued after received the Client ID
201 from the server. Affected file lib/silcclient/client.c.
203 * The CMODE_CHANGE notify may now return also an SilcServerEntry
204 to the application as the mode changer might be server.
205 It is guaranteed that NULL is not returned anymore to the
206 application. Affected file lib/silcclient/client_notify.c.
208 The ID Type is now also passed to the application so that
209 it can check whether the returned entry is SilcClientEntry
212 Added new function silc_client_get_server_by_id to return
213 the server entry by ID. Affected files are the
214 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
216 * Do not create the channel in the Irssi SILC Client when issuing
217 the JOIN command but when received the sucessful JOIN command
218 reply. Otherwise the channel might get created even though we
219 could not join it. The Affected file is
220 irssi/src/silc/core/[silc-channels.c/client_ops.c].
222 * Fixed a channel joining bug in router. The router must also
223 check the channel modes, invite and ban lists etc. when serving
224 the JOIN command sent by normal server. Affected file is
225 silcd/command.c. The router now resolves the client's
226 information from the server who sent the JOIN command if it
227 does not know it, and processes the JOIN command only after
230 * Changed the SilcCommandCb to take new argument; void *context2.
231 Affected file lib/silccore/silccommand.h
233 The second argument in the command callbacks in the server now
234 includes the SilcServerCommandReplyContext if the command was
235 called as pending command callback from the command reply.
236 Otherwise it is NULL. When called as pending the status of the
237 command reply will be checked and if it was erronous the
238 error will be sent to the original sender of the command.
239 This way the client always receives the error messages even
240 though the server was actually the one who received the error
241 when it resent the command to router, for example. Affected
242 files silcd/command[_reply].[ch].
244 * Fixed sending WHOWAS command's error message to client if
245 the requested client could not be found. It was missing.
248 * Changed the CMODE and CUMODE commands reply arguments in the
249 protocol specification. The Channel ID is now sent in both
250 of the commands to identify the channel. Implemented this
251 new feature to the client and server. Affected files
252 lib/silcclient/command_reply.c and silcd/command.c.
254 * Made better checks for invite and ban lists in the JOIN
255 command in server. Affected file silcd/command.c.
257 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
259 * The server now performs the incoming host IP/DNS lookup
260 using the silc_socket_host_lookup and thus does not block
261 the server anymore. Affected file silcd/server.c.
263 * Completed the multi-thread support for SILC Scheduler in
264 the lib/silcutil/silcschedule.c.
266 * Fixed the configure.in.pre to detect the pthread correctly
269 * Fixed a deadlock in silc_task_queue_wakeup in the file
270 lib/silcutil/silctask.c.
272 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
274 * Added new function silc_schedule_wakeup that is used in
275 multi-threaded environment to wakeup the main thread's
276 schduler. It needs to be used when a thread adds a new task
277 or removes a task from task queues. After waking up, the
278 scheduler will detect the task queue changes. If threads
279 support is not compiled in this function has no effect.
280 Implemented the wakeup mechanism to both Unix and WIN32
281 systems. Affected files are lib/silcutil/silcschedule.[ch],
282 lib/silcutil/unix/silcunixschedule.c and the
283 lib/silcutil/win32/silcwin32schedule.c.
285 * Added new function silc_task_queue_wakeup to wakeup the
286 scheduler by the specified task queue. Affected file
287 lib/silcutil/silctask.[ch].
289 * The silc_socket_host_lookup_start now wakes up the scheduler
290 after adding the timeout task. Affected file is
291 lib/silcutil/silcsockconn.c.
293 * The silc_socket_host_lookup is synchronous now if the threads
294 support is not compiled in. However, the callback is still
295 called asyncronously through the scheduler, anyway. Affected
296 file lib/silcutil/silcsockconn.c.
298 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
300 * Added new function silc_socket_host_lookup to perform
301 asynchronous IP and FQDN lookups for the socket connection.
302 Affected files lib/silcutil/silcsockconn.[ch].
304 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
306 * Added SILC_MUTEX_DEFINE to define the mutex on environments
307 that may or may not compile the mutex support in.
309 Changed the silc_mutex_alloc interface. It allocates the
310 mutex now to the sent pointer and returns TRUE or FALSE.
312 Affected file lib/silcutil/silcmutex.h.
314 * Wrote the SILC Task Queue interface to support multi-threads.
315 Affected file lib/silcutil/silctask.[ch].
317 * Wrote the SILC Scheduler to support multi-threads. Affected
318 file lib/silcutil/silcschedule.c.
320 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
322 * Implemented the SILC Mutex API and SILC Thread API for WIN32
323 in lib/silcutil/win32/.
325 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
327 * Defined SILC Mutex API and SILC Thread API and implemented
328 them for Unix. Affected files are
329 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
330 lib/silcutil/unix/silcunixmutex.c and
331 lib/silcutil/unix/silcunixthread.c.
333 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
335 * Fixed the silc_server_remove_clients_by_server's channel
336 key re-generation. The hash table handling was incorrect
337 and would not work with many channels. Affected file is
340 * Fixed some memory leaks around the server code.
342 * Rewrote the silc_server_get_users_on_channel to support IPv6
343 based Client ID's. Affected file silcd/server.c.
345 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
346 specification. However, a separate document must be written
347 to define the detailed signing procedure and the payload
348 associated with the flag. Defined the flag to the
349 lib/silccore/silcchannel.h as well.
351 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
353 * Changed the dynamic tables to static size tables in the
354 lib/silccrypt/silchmac.c.
356 * Removed GCC dependencies from the code. A patch by cras.
358 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Do not show the error "Error receiving packet bla bla"
361 in server if it really was not an error (-2 means that reading
362 is pending). Affected file silcd/server.c.
364 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Fixed a possible crash in silc_server_remove_clients_by_server
367 in silcd/server.c. Fixed there also some memory leaks.
369 * Fixed the silc_idlist_replace_client_id. It could replace
370 wrong key in the hash table. Affected file silcd/idlist.c.
372 * Do not check whether there are global users on the channel
373 if the channel->global_users is FALSE. Affected functions
374 silc_server_remove_from_one_channel and
375 silc_server_remove_from_channels in silcd/server.c. Also,
376 do not check if the removed client is local as we can be
377 sure that global client was not removed from the channel
378 and checking for global users is not needed.
380 * The silc_server_remove_clients_by_server now re-generates
381 the channel keys correctly for those channels that had
382 clients removed from them. Affected file silcd/server.c.
384 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
386 * Found the reason of random crashes in the server. We weren't
387 ignoring the SIGPIPE signal (which can be sent in write())
388 and it crashed the server. Affected file silcd/silcd.c.
390 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
392 * Assure that sock->user_data is not NULL in the function
393 silc_server_packet_send in silcd/packet_send.c.
395 * Disconnect the remote connection if it could not be added
396 to any ID lists in the server. The affected file is
399 * Check in silc_server_packet_send[_real/dest] that the
400 socket is not disconnecting and ignore the data if it is.
401 Affected file silcd/packet_send.c.
403 * Define inline to __inline on native WIN32 compilation.
404 Affected file includes/silcwin32.h.
406 * Added some explicit type casts for inline code since MSVC
407 require them. Affected files lib/silcutil/silcbuffer.h,
408 lib/trq/silcdlist.h and lib/trq/silclist.h.
410 * Print warning in log files from now on if the packet
411 decryption fails. Affected file silcd/server.c.
413 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
415 * Changed the `say' client operation's interface to accept
416 new `type' argument to indicate the type of the message sent
417 by the library. The application may filter the library's
418 messages according the type. The affected file is the
419 lib/silcclient/silcapi.h.
421 * Added two new functions to lib/silcclient/silcapi.h:
422 silc_client_del_client and silc_client_del_client_by_id.
423 Affected file lib/silcclient/idlist.c.
425 * Moved the clientincludes.h from includes/ to silc/ and
426 serverincludes.h from includes/ to silcd/.
428 * The modes for the CMODE and CUMODE are now passed as
429 uint32 for application with COMMAND_REPLY. The affected
430 file is lib/silcclient/command_reply.c.
432 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
434 * /WHOIS without arguments shows client's own information.
435 Affected file lib/silcclient/command.c.
437 * Changed PING to not accept any arguments. The specs
438 says that client can ping only the connected server so
439 requiring an argument is not needed. Affected file is
440 lib/silcclient/command.c.
442 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
444 * Fixed a fatal bug in private message sending and reception
445 encryption and decryption when using private message keys.
446 The implementation was incorrect and did not follow the
447 specification. It causd that some of the message were
448 lost since it did not use the sending and receiving keys
449 as the protocol suggests. This has been fixed and will cause
450 incompatibilities with older clients when sending private
451 message encrypted with private message keys. Affected files
452 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
453 and various other in Irssi SILC Client.
455 Added `responder' boolean argument to the functions
456 silc_client_add_private_message_key[_ske] to indicate when
457 the key is added as responder or initiator of the key
460 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
462 * Removed the silc_ske_check_version function and created
463 a SilcSKECheckVersion callback. Added also a function
464 silc_ske_set_callbacks that is now used to set all SKE
465 callbacks. The callback functions are not given to
466 the SKE functions anymore, but this function is used to
469 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
471 * Added `silc_version' argument to the silc_client_alloc
472 to define the version of the application for the library.
473 The library will use the version string to compare it
474 against the remote host's (usually a server) version
475 string. Affected file lib/silcclient/silcapi.h
477 * Added the KE protocol context to Key Agreement context
478 in client library so that we can abort the SKE if it
479 is in process when we get timeout. Affected file is
480 lib/silcclient/client_keyagr.c.
482 * Do not resolve the client ID forever if it returns in the
483 first time that such client does not exist. This was done
484 for example with private message. Affected file is
485 lib/silcclient/client_prvmsg.c.
487 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Do not add regex.h for WIN32. The affected file
490 includes/silcincludes.h.
492 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
493 not work yet 100%. It generates the DLL's automatically
494 when compiling with --with-win32 under cygwin.
496 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
498 * lib/contrib/regex.c is not compiled on WIN32.
500 * Added silc_net_get_socket_opt function to the
501 lib/silcutil/silcnet.h.
503 * Added includes/silcwin32.h for WIN32 specific includes
506 * Do not use ptime structure or any of the posix process
507 functions on WIN32 in lib/silccrypt/silrng.c.
509 * Added silc_gettimeofday to provide generic function
510 for struct timeval on all platforms. Added the function
511 to lib/silcutil/silcutil.h.
513 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
515 * Moved the lib/silccore/silcsockconn.[ch] to the utility
516 library as they clearly belong there. As a plus side we
517 can make the actual socket connection routines platform
520 Added also new generic function silc_socket_read and
521 silc_socket_write (that used to be silc_packet_[read/write].
522 The implementation of these are platform specific.
524 * Added WIN32 specific routines of silc_socket_[read/write]
525 to lib/silcutil/win32/silcwin32sockconn.c.
527 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Added preliminary support for native WIN32 compilation under
530 cygwin (using the -mno-cygwin option for GCC) to the
531 ./configure.in.pre. The --with-win32 now prepares the
532 compilation for native WIN32.
534 * Rewrote the SILC Scheduler interface in the file
535 lib/silcutil/silcschedule.h. The scheduler is now context
536 based and does not have anymore any global static scheduler.
537 Moved the Unix scheduler to the lib/silcutil/unix/ directory
538 and created lib/silcutil/win32 directory for WIN32 based
541 * Added Unix specific network routines to the
542 lib/silcutil/unix/silcunixnet.c and the old
543 lib/silcutil/silcnet.c includes now only generic routines.
545 Added WIN32 specific network routines to the
546 lib/silcutil/win32/silcwin32net.c.
548 * Added Unix specific utility functions from the
549 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
551 * Added WIN32 SILC Scheduler to the file
552 lib/silcutil/win32/silcwin32schedule.c. The code is of course
555 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Do not handle JOIN notify in the server if the target client
558 is not registered (idata->registered == FALSE). The affected
559 file is silcd/packet_receive.c.
561 * Update the nickrec->founder in event_cumode in the Irssi SILC
562 client. Affected file irssi/src/silc/core/silc-channels.c.
564 * Fixed the CUMODE_CHANGE notify handling in the server when
565 server and router are announcing their clients on channels.
566 Now the mode changes are saved and notified correctly. The
567 affected file is /silcd/packet_receive.c.
569 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
570 They really did not replace the cache entry in the ID Cache.
571 Now they do that. Affected file silcd/idlist.c.
573 * Fixed the KICK notify handling in the Irssi SILC client to
574 update the channel records so that the kicked client does not
575 appear to be on the channel. The affected file is
576 irssi/src/silc/core/silc-channels.c.
578 * Always update the conn->current_channel when executing command
579 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
581 * Fixed the KILL notify handling in Irssi SILC client to remove
582 the killed client on all channels.
584 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Fixed the silc_parse_command_line to remove extra spaces
587 from the start and end of the arguments. Affected file is
588 lib/silcutil/silcutil.c.
590 * Cancel and free any active protocol in the function
591 silc_server_close_connection. Affected file silcd/server.c.
593 * Cancel and free any active protocol in the function
594 silc_client_close_connction. Affected file is
595 lib/silcclient/client.c.
597 * Do not execute the KILL command for clients that are in
598 history (ie. they are not in the network). Affected file is
601 * Fixed KILL notify handling, client does not crash anymore.
602 Affected file irssi/src/silc/core/silc-channels.c.
604 * Reduced the default packet buffer size from 2048 to 1024 in
605 lib/silccore/silcpacket.c.
607 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
608 counter to the SKE context that is incresed when the SKE library
609 performs async operation outside the library. If the outside
610 process frees the SKE context and FREED status will be set
611 and the library will detect after the sync operation that the
612 libary is freed. The affected files are
613 lib/silcske/silcske[_status].[ch].
615 * Resolve the client entry information in the function
616 silc_client_channel_message to assure that NULL pointer is not
617 passed as client entry to the application. */
619 * Fixed the task timeout calculation to assure that there is
620 never negative timeouts. The affected file is
621 lib/silcutil/silcschedule.c.
623 * Fixed the channel user mode notification sending in server.
624 It was sent point-to-point to the router (or to server by router)
625 but it needs to be destined to a channel. The routines now
626 supports sending the channel user mode notifys to the channels
627 when announcing clients and channels. Affected files are
628 silcd/server.c and silcd/packet_receive.c.
630 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
631 It did not actually replace the old channel entry in the cache.
632 Affected file lib/silcclient/client_notify.c.
634 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Fixed a possible crash in silc_packet_send_prepare. It now
637 assures always that there is enough space in the buffer and
638 at the tail area of the buffer (for MAC).
640 Fixed the inbound buffer reallocation in silc_packet_read.
641 It was old code and did not handle the reallocation correctly.
644 The affected file is lib/silccore/silcpacket.c.
646 * Fixed buffer overflow in silc_parse_nickname in the file
647 lib/silcutil/silcutil.c.
649 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * make install generates new server keys only if there is not
654 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
657 Added check that if the NOREPLY is set then we will not send
658 the away message. This avoids infinite loop of away messages
659 if both clients are away. The affected file is
660 lib/silcclient/client_prvmsg.c.
662 * Fixed client crash if /NICK was given without arguments.
663 Affected file lib/silcclient/command.c.
665 * Server does not send the invite list in INVITE command back
666 to the client if the list was not altered. Added this notion
667 to the protocol spec as well. Affected file silcd/command.c.
669 Fixed possible crash in INVITE command by checking the
670 value of silc_server_get_client_route command.
672 * Fixed the INVITE notify type handling. The arguments are now
673 taken in correct order and client does not crash. The affected
674 file is irssi/src/silc/core/silc-channels.c.
676 Removed the "Inviting xxx to channel" message from the
677 client library away and let the application handle it.
678 Affected file lib/silcclient/command.c. Added that message
679 to Irssi SILC client's message formats.
681 * Fixed CMODE command crash in client. It now checks the
682 amount of arguments correctly and does not crash. The affected
683 file is lib/silcclient/command.c.
685 * Do not create new channel automatically in silc_channels_join
686 but check whether the channel by that name already exists.
687 Affected file irssi/silc/core/silc-channels.c.
689 * Do not send the SERVER_SIGNOFF to router if the disconnected
690 entity was the router. Affected file silcd/server.c.
692 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
693 SILC client as it was missing from there.
695 Added the handling of the KICK notify to the Irssi SILC client
696 as it was missing. Added "you have been kicked" message to
697 Irssi SILC client's message modules formats.
699 Added the handing of the KILL notify to the Irssi SILC client
700 as it was missing. Added the kill message module formats
703 The affected file is irssi/src/silc/core/silc-channels.c.
705 * The router did not save the channel mode the server announced.
706 Affected file silcd/packet_receive.c.
708 * Fixed a possible crash in INFO command in server. If the
709 server did not provide the server info it crashed. Affected
710 file silcd/command.c.
712 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Fixed the GETKEY command in the server to check also the
715 global list. Otherwise the GETKEY would not work correctly
716 in normal SILC server. Affected file silcd/command.c.
718 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Fixed GETKEY crash, it crashed if the command did not succseed.
722 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
725 is now real and not just an macro interface to GMP.
727 Removed the entire GMP from the source tree and imported new
728 NSS MPI library instead. Reason for removing GMP is that it is
729 extremely large and compiles extremely slow. The NSS MPI
730 is only a few files and compiles in less than 10 seconds.
731 The speed is also about the same as GMP. The MPI is imported
734 If the system has GMP installed we will still use the GMP.
735 If it is not then the NSS MPI will be compiled.
737 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Merged a long nickname (127 characters long) crash bugfix from
740 Irssi CVS tree. Affected file irssi/src/core/misc.c.
742 * Merged a freed memory reference bugfix from Irssi CVS tree.
743 Affected file irssi/src/core/commands.c.
745 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Added the server's public key sving and verification to the
748 server when performing the SKE. This was missing and the
749 remote server's (or router's) public key was accepted without
750 checking whether we have it previously or trust it at all.
751 Affected file silcd/protocol.c.
753 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Check in the silc_server_timeout_remote if protocol is active
756 and make sure that the protocol's final callback is called so
757 that all memory if freed. Affected file silcd/server.c.
759 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * silc_server_whois_send_reply crashed the server if the nickname
762 was 127 characters long. Affected file silcd/command.c.
764 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
766 * Added sanity check to the silc_server_new_client. If the hostname
767 is provided inside username then check that the provided hostname
768 really is the same as the resolved one. If the hostname was not
769 resolved then check it from the public key. Affected file is
770 silcd/packet_receive.c.
772 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
773 if the server disconnected us and the connection is not valid
774 anymore. Affected file irssi/src/silc/core/silc-channels.c.
776 * Moved the silc_client_[chmode|chumode|chumode_char] away from
777 the library to the lib/silcutil/silcutil.[ch].
779 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Close log file after open. Affected file
782 lib/silcutil/silclog.c.
784 * Check whether sock == NULL in silc_client_send_packet and return
785 if it is. Affected file lib/silcclient/silcclient.c.
787 * Check rec->entry == NULL in the Irssi SILC Client before
788 sending the channel message. Affecte file is
789 irssi/src/silc/core/silc-servers.c.
791 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Merged a splitted window bugfix from Irssi CVS tree. The
794 affected file is irssi/src/fe-text/textbuffer-view.c.
796 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
797 It did not print nickname.
799 * Improved the distributions system a bit.
801 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
804 irssi/src/fe-text/gui-window.c.
806 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
807 to in-active server. The affected file is
808 irssi/src/silc/core/client_ops.c.
810 * Resolve the client in USERS command reply if the entry does
811 not have username resolved. The affected file is
812 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
813 command to WHOIS command to really resolve stuff. The USERS
814 is not used any more in any critical section so WHOIS can
815 be used even though it might be slower than IDENTIFY.
817 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
820 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Changed the protocol API a bit more consistent in the
823 lib/silccore/silcprotocol.[ch].
825 * Changed the following headers to ROBODoc format:
827 lib/silccore/silcpayload.h
828 lib/silccore/silcprotocol.h
829 lib/silccore/silcsockconn.h
831 All core library headers are now formatted.
833 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Fixed a bug in Irssi SILC client; do not show that you are
836 server/router operator if you really are not. Affected file is
837 irssi/src/silc/core/client_ops.c.
839 * Renamed silc_command_free_payload to silc_command_payload_free.
840 Affected file lib/silccore/silccommand.h
842 * Added silcmath.h to include the prototoypes of various routines
843 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
846 * Changed the following headers to ROBODoc format:
848 lib/silccore/silcchannel.h
849 lib/silccore/silccommand.h
850 lib/silccore/silcid.h
851 lib/silccore/silcidcache.h
852 lib/silccore/silcmode.h
853 lib/silccore/silcnotify.h
854 lib/silccore/silcpacket.h
855 lib/silcmath/silcmath.h
857 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
859 * Added checking to the server code not to start the server if
860 ciphers and stuff are not configured properly. Affected files
861 silcd/serverconfig.[h] and silcd/server.c.
863 * Changed the layout of the header files of the public interfaces
864 in the SILC libraries. The new layout supports ROBODoc
865 documentation tool (and some others) so that it is easy to create
866 a library reference manual. All the other headers and source
867 code must still follow the CodingStyle document. Also source
868 code must not include these ROBODoc stuffs, only the headers.
869 Furthermore, all public interface headers must now be named
870 by using `silc' prefix, example: silcapi.h, silccipher.h.
871 Some files were renamed due to this. All the other headers
872 must not be used as public interfaces. I will update the
873 CodingStyle document later. Changed following headers, so far:
875 lib/silcclient/silcapi.h
876 lib/silccore/silcauth.h
877 lib/silccore/silcprivate.h
878 lib/silccrypt/silcdh.h
880 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Removed silc_client_packet_send_flush from the client library
885 as it is not needed. Affected file lib/silcclient/client.[ch].
887 * Added printing of message of unresolved authentication method
888 to the Irssi SILC client. Added it to the module formats.
889 Removed the same message from the client library.
891 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Added new distribution feature, DISTLABEL. Every distribution
894 can define own preprocessor label that can be used in the
895 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
896 file distributions, acconfig.h.pre and prepare.
898 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Added Makefile.defines_int to include the actual definitions
901 for Makefile.defines.in. Tested the new distribution system,
902 created distributions and tested installation.
904 * Added AWAY message printing to the Irssi SILC client. Added
905 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
907 * Added SCONNECT command to call the SILC's CONNECT command.
908 Cannot use CONNECT directly since Irssi uses that internally.
909 Affected file irssi/src/silc/core/silc-servers.c.
911 Added ACTION local command. It is same as ME command but takes
912 the channel as mandatory argument.
914 Rewrote some of the Irssi's help files to suite for SILC
917 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Added Makefile.defines[.in] that should for now on be included
920 in all Makefile.am file in the source tree. That file includes
921 all common compilation definitions for SILC source tree.
923 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Minor changes to the ./prepare script to change the package
926 name according the distribution name to the configure.in.
928 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Created new distribution system. Added file `distributions'
931 that defines all the distributions that can be created out of
932 the SILC source tree. The ./prepare script now reads that
933 file to determine how to prepare the distributions. The
934 first argument to the ./prepare is the name of the distribution
935 and second is the version of the distribution. If given
936 without arguments it creates the default (toolkit) distribution
937 with the default version (defined in ./prepare).
939 All Makefile.am files that are subject to the distributions
940 are now named as Makefile.am.pre. These are ./Makefile.am
941 and lib/Makefile.am. Others may be changed later.
943 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Added invite list, ban list, some key management and connection
946 error message printing to module formats in the Irssi SILC client.
948 * Added new silc_client_set_away_message to set the away message
949 that is back to the person who sent private message. The
950 affected file lib/silcclient/silcapi.h and the
951 lib/silcclient/client_prvmsg.c.
953 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Fixed the private message sending in the Irssi SILC client,
956 added local command KEY to the Irssi SILC client.
958 Added key management and key agreement message formats to the
959 irssi/src/fe-common/silc/module-formats.[ch].
961 Added USERS (alias WHO) printing, server/router operator
962 indication and LIST command printing to the module formats.
964 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Fixed channel joining notify handling, cumode notify handling
967 from Irssi SILC client.
969 * Added SILC specific module-formats to the Irssi SILC client so
970 that SILC specific message hilighting, colors etc is possible.
971 Affected file irssi/src/fe-common/silc/module-formats.[ch].
973 Added channel mode, channel user mode, actions, notices,
974 whois and whowas printing to the the module-formats.c.
976 * Fixed a bug in channel deletion in the server. The channel
977 is not left to the cache even if the channel founder auth mode
978 is set when there are no users anymore on the channel. Affected
981 * The silc_net_localhost now resolves the entire hostname including
982 the domain name. Affected file lib/silcutil/silcnet.c.
984 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Changed the ask_passphrase client operation to be ascynchronous.
987 It has now a completion callback and a context that the
988 application must call after it has got the passphrase from
989 the user. Affected files lib/silcclient/silcapi.h,
990 lib/silcclient/protocol.c, lib/silcclient/command.c and
993 Added SilcAskPassphrase callback that the application calls
994 to deliver the passphrase to the library.
996 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
997 The public key verification and especially a certificate
998 verification is asynchronous procedure.
1000 Added new SILC_SKE_STATUS_PENDING status to indicate the
1001 request is pending and a callback will be called to finalize
1004 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1005 indicate that remote end did not send its public key (or
1006 certificate), even though we require it. Added check for this
1007 condition in the SKE. This was a security bug, now fixed.
1009 Defined new SilcSKEVerifyCbCompletion callback that is called
1010 when the verification process is completed.
1012 The affected files lib/silcske/silcske_status.h and
1013 lib/silcske/silcske.[ch].
1015 * Changed the verify_public_key client operation to be async
1016 as well. Defined SilcVerifyPublicKey callback that is used to
1017 indicate the success of the public key verification process.
1019 Changed the server and client to use the new async client
1022 * Changed the Irssi SILC client's internal scheduler to be called
1023 twice as many times as it used to be. As a result the client
1024 should be a bit faster now. Affected file is
1025 irssi/src/silc/core/silc-core.c.
1027 * Added support to Irssi SILC client of asynchronous public key
1028 verification and passphrase inquiry. Affected file is
1029 irssi/src/silc/core/silc-core.c.
1031 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Do not say "You have left channel %s" in client library.
1034 Moved it to the application. Affected files are
1035 lib/silcclient/command.c and silc/client_ops.c.
1037 * Fixed silc_client_get_clients. Command context was not
1038 duplicated and was freed memory in the callback. Affected
1039 file lib/silcclient/idlist.c.
1041 * Do not say "you are now talking..." on JOIN command in the
1042 client library. The appliation must handle it.
1044 * Do not say ".. changed topic to" in command reply in the
1045 client libary. The application must handle it.
1047 * Fixed TOPIC command sending in the client library.
1049 * Fixed a memory leak in silc_client_command_free in the file
1050 lib/silcclient/command.c.
1052 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Imported a modified version of Irssi client to the source tree.
1055 The Irssi will be used to create a new client called
1056 Irssi SILC. Imported to irssi/.
1058 Added silc_core_init_finish function to the Irssi. Affected
1059 file irssi/configure.in.
1061 A lot changes in the Makefile.ams around the irssi tree.
1063 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1065 * Do not rehash if the new size is same as the old size of the
1066 hash table, in the silc_hash_table_rehash*. The affected file
1067 lib/silcutil/silchashtable.c.
1069 * Replaced hash_table_del_by_context calls from the server
1070 (when channel->user_list and client->channels) to the
1071 hash_table_del as it is sufficient and faster.
1073 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Added silc_hash_table_list, silc_hash_table_get and the
1076 SilcHashTableList structure to provide an alternative way to
1077 traverse the hash table. The affected files are
1078 lib/silcutil/silchashtable.[ch].
1080 * Changed the server's idlist routines to use the hash table
1081 routines to optimize the code.
1083 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Replaced the client entry's `channel' list and channel entry's
1086 `user_list' list to hash tables for optimized lookup. Changed
1087 the code to use the hash table interface around the code.
1088 Affected file lib/silcd/idlist.[ch].
1090 * Added `auto_rehash' boolean argument to the function
1091 silc_hash_table_alloc to indicate whether the hash table should
1092 auto-rehash when it thinks is appropriate time. It will
1093 increase the hash table size if the there is twice as much
1094 entries in the table than the size of the table, and will
1095 decrease the size if there are twice as less entries than
1096 the size of the table.
1098 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1102 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * silc_idcache_purge_by_context deletes the entry now by context
1105 as it is supposed to do. Affected file lib/silccore/idcache.c.
1107 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1108 client is not anymore valid (WHOWAS givens the info) and not
1109 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1111 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Removed the `data' and `data_len' arguments from the ID Cache
1114 interfaces and added `name' argument. ID Cache does not handle
1115 anymore the binary data only a names associated with given ID.
1117 * When hashing a Client ID with silc_hash_id the entire ID is
1118 not hashed anymore, instead only the hash of the Client ID is
1119 hashed. This way we can access the Client ID from the cache
1120 with Client ID but with the hash of the ID (which is a hash of
1121 the nickname) as well without any difference in performance.
1123 Added also silc_idcache_find_by_id_one_ext to do one on one
1124 searching when we have the actual ID. Added also function
1125 silc_hash_client_id_compare. The affected files are
1126 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1128 * When hashing the name associated with a ID it is always done
1129 in lowercase. This way we can access the cache without worrying
1130 about case-sensitivity, even though, for example nicknames are
1133 * Fixed a bug in server with channel message sending. It put
1134 wrong ID type as destination ID. The affected file
1135 silcd/packet_send.c.
1137 * silc_idcache_del_by_context now deletes from all hash tables
1138 by context. Affected file lib/silccore/idcache.c.
1140 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Changed the client library to use the new ID Cache interface.
1143 Changes around the source tree.
1145 * Added silc_hash_table_rehash_ext to rehash with specific
1146 hash function. Affected file lib/silcutil/silchashtable.[ch].
1148 * Added silc_hash_string_compare to compare two strings in the
1149 hash table. Affected file lib/silcutil/silcutil.[ch].
1151 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Added new function silc_idcache_del_by_context into the
1154 lib/silccore/idcache.[ch].
1156 * Changed the server's ID list routines to use the new ID Cache
1157 interface. Changes around the source tree.
1159 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Added silc_hash_table_del[_by_context]_ext functions in to the
1162 lib/silcutil/silchashtable.[ch].
1164 Removed silc_hash_table_find_all* routines and added new
1165 silc_hash_table_find_foreach to replace them.
1167 Added silc_hash_table_replace_ext function as extended
1168 replacing function. Separated the simple hash table interface
1169 from the extended hash table interface in the file
1170 lib/silcutil/silchashtable.h.
1172 * Fixed minor bugs and changed it to use some of the new
1173 hash table functions in lib/silccore/idcache.c
1175 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1177 * Added new function silc_hash_table_find_all to return all keys
1178 in the hash table by the specified key. As the hash table is
1179 collision resistant it also makes it possible to have several
1180 duplicate keys in the hash table. This function may be used to
1181 find all of the keys from the hash.
1183 Added user_context arguments to the SilcHashFunction,
1184 SilcHashCompare and SilcHashDestructor to deliver user specified
1187 Added new fuctions silc_hash_table_find[_all]_ext to do
1188 extended lookup with specified hash and compare functions and
1189 specified user contexts.
1191 Added new function silc_hash_table_add_ext to add the key
1192 with specified hash function and user context.
1194 Added new function silc_hash_table_foreach to traverse all
1195 entrys in the hash table. Added SilcHashForeach callback
1198 Added new function silc_hash_table_del_by_context to delete
1199 the entry only if the context associated with the key matches.
1201 Affected files are lib/silcutil/silchashtable.[ch].
1203 * Removed silc_hash_[server/client/channel]_id and added just
1204 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1205 silc_hash_id_compare to compare two ID's using as the hash table
1206 comparison function. Added also silc_hash_data to hash
1207 binary data and silc_hash_data_compare to compare it.
1209 * Removed silc_idlist_find_client_by_hash as it is not needed
1210 anymore. Affected file silcd/idlist.[ch].
1212 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1213 to use internally the SilcHashTable. The new ID Cache is a lot
1214 faster than the old one. Some of the ID Cache interface was also
1215 rewritten and obsolete and stupid functions were removed.
1217 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Added entry_count field to the SilcHashTable to keep the number
1220 of the entries in the table. Implemented the function
1221 silc_hash_table_rehash. Added new function
1222 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1224 Fixed a minor bug in silc_hash_table_free.
1226 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1227 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1228 into the lib/silcutil/silcutil.[ch].
1230 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * Implemented a collision resistant hash table into the
1233 lib/silcutil/silchashtable[ch]. See the header and the source
1234 for the SilcHashTable API.
1236 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Merged dotconf version 1.0.2 into lib/dotconf.
1240 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Do not compile anything in lib/silcsim/* if the SIM support
1243 is not enabled. The tree should now compile without problems
1246 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Compiled the SILC under cygwin. Compiled and tested briefly
1249 without problems. More tests needed. The SIMs didn't compile
1252 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1254 * Fixed possible crash in silc_get_username in the
1255 lib/silcutil/silcutil.c.
1257 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Fixed a va_arg in silc/client_ops.c.
1261 * Oops, RC5 routines were named AES and caused some problems
1262 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1264 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Added new SilcIDIP structure into the lib/silccore/id.h and
1267 replaced the old `ip' fields from all SILC ID's to that type.
1268 This is a step towards IPv6 support.
1270 The silc_id_get_len takes now the ID as an extra argument.
1271 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1272 both IPv4 and IPv6 based ID's.
1274 The affected files are lib/silccore/id.[ch] and other files
1275 around the tree using these routines.
1277 * Removed the ID length arguments in server from various
1278 silc_server_send_notify_* routines -> they are not needed
1281 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Fixed memory leak in silc_encode_pem_file in the file
1284 lib/silcutil/silcutil.c.
1286 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1288 * Check minor version as well in the SKE. Affected files are
1289 silcd/protocol.c and lib/silcclient/protocol.c.
1291 * Added --identifier option to the server so that an identifier
1292 can be when creating the public key for the server. Affected
1293 file is silcd/silcd.c.
1295 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1296 lib/silccrypt/silcpkcs.c.
1298 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Register default ciphers and stuff when using -C option with
1301 the server. Affected file sildc/silcd.c.
1303 * Put back the servers public key filename format, it is better
1304 than the new one. For now, the client keys are saved with the
1305 new filename format. The affected file silc/client_ops.c.
1307 * Implemented the Cipher API for the rest of the ciphers that
1308 did not implement it or implemented it the wrong way.
1310 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1312 * Register default ciphers and stuff when using the -S option
1313 in the client. Affected file silc/silc.c. Same also when
1314 creating new key pair with -C option.
1316 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Fixed the silc_verify_public_key client operation function to
1319 save the public keys differently. The fingerprint is now
1320 used as filename and not the hostname. This way also the
1321 client keys are saved uniquely and not with hostnames. The
1322 affected file is silc/client_ops.c.
1324 * Trimmed the silc_hash_fingerprint function to remove extra
1325 whitespaces from the end of the fingerprint. The affected
1326 file is lib/silccrypt/silchash.c.
1330 * Added silc_cipher_register_default function to register all
1331 default ciphers. It can be used when configuration files
1332 does not exist and the application does not want any specific
1333 ciphers in any specific order.
1335 The SilcDList is now used as silc_cipher_list dynamically
1336 allocated cipher list. Removed the static list all together
1337 and now all ciphers must be allocated to the dynamic list.
1338 The silc_cipher_alloc routine was changed to check only the
1341 All silc_cipher_* routines that used to return int returns
1344 The affected files lib/silccrypt/silccrypt.[ch].
1346 * The same thing was done to silc_hash_* as for silc_cipher_*
1347 routines. Affected files lib/silccrypt/silchash.[ch].
1349 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1350 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1351 Added also silc_pkcs_[un]register[_default] functions.
1352 Removed the data_context from the PKCS API.
1354 * Added silc_hmac_register_default function to register default
1355 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1356 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1357 to unregister all hmacs at once.
1359 * Register the default ciphers, hash functions, PKCSs and HMACs
1360 if client's configuration file does not exist. The affected
1363 * The client did not load the hash functions from the SIM
1364 modules at all. Added support for this. Affected file is
1365 silc/clientconfig.c.
1367 * When decoding public key with silc_pkcs_public_key_decode, check
1368 the supported algorithm only if PKCS are registered. Affected
1369 file lib/silccrypt/silcpkcs.c. The same was done with the
1370 silc_pkcs_private_key_decode.
1372 * Fixed the SILC List routines to keep the list always in order.
1373 It used to change the list's order when traversing the list but
1374 not it preserves the order. Affected file lib/trq/silclist.h.
1376 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1378 * Added the client library to use the SilcSocketConnection's
1379 reference counter (by silc_socket_dup) to prevent the bug that
1380 the socket object may be freed underneath async operation.
1382 * The name resolv library checking fixes in the configure.in.pre.
1385 * Created new version of the protocol drafts for future
1386 development. The -03 drafts are the ones that will be changed
1387 in the trunk now and the -02 will remain as they are.
1389 * Send list of CUMODE notifys to the router when announcing
1390 the channel users to the router. Affected file silcd/server.c.
1391 If the router receiving channel founder CUMODE for a channel
1392 that already has channel founder it will send CUMODE notify
1393 to the sender to remove the channel founder rights from the
1394 announced client. Affected file silcd/packet_receive.c.
1396 * The CUMODE notify may now use Server ID as well as the entity
1397 who changes the mode. Updated protocool specs.
1399 * Updated INSTALL and README files.
1401 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * New web pages in the http://silc.pspt.fi. The pages was
1408 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1410 * Implemented the [DenyConnectin] config section in the server.
1411 Added silc_server_config_denied_conn to check whether incoming
1412 connection is denied. Affected file silcd/serverconfig.[ch].
1414 * Do not check the ports when checking the incoming configuration
1415 data if the port is 0, meaning any. Affected file is
1416 silcd/serverconfig.c.
1418 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1420 * Fixed buffer overflow in silc_string_compare in the file
1421 lib/silcutil/silcutil.c.
1423 * Fixed double free in silc_server_command_leave in the file
1426 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Fixed the version checking in the server. Affected file is
1431 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Fixed the configuration data fetching when accepting new
1434 connections in the server. Affected file silcd/server.c.
1436 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Added `sender_entry' argument to the function
1439 silc_server_packet_relay_to_channel so that we can check
1440 whether some destination actually belongs to the same route
1441 the sender belongs (ie, we must not resend the packet to the
1442 sender). Affected file silcd/packet_send.[ch].
1444 * Added `servername' field to the SilcClientEntry in the server
1445 to hold the name of the server where client is from. Affected
1446 file is silcd/idlist.h.
1448 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Moved the channel message encrypting in the router betwen
1451 router connections from silc_server_channel_message to the
1452 silc_server_packet_relay_to_channel since we want to check
1453 whether we have anybody channel before encrypting anything.
1454 Affected files silcd/packet_[receive/send].c.
1456 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Fixed the [AdminConnection] server config section to support
1459 multiple entries. Affected file silcd/serverconfig.c.
1461 * Added support into the server to check the validity of the
1462 incoming connection before executing any KE or authentication
1465 * The connection configuration is now saved to the KE and
1466 connection auth protocol contexts and not fetched anymore in
1467 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1469 * The local hosts listenning address and port is also resolved
1470 now when starting the server. We want to have the socket object
1471 to include the real address and port for the listener. Added
1472 new function silc_net_check_local_by_sock into the files
1473 lib/silcutil/silcnet.[ch].
1475 * Fixed a broadcast bug in server -> do not broadcast if we
1478 * Fixed a routing bug. Do not route broadcast packets ever.
1479 Broadcast packets must be processed always and not routed since
1480 they may be destined to some other host than yourself and thus
1481 would get routed without no good reason. Affected file is
1484 * Added function silc_server_config_is_primary_route to check
1485 whether primary router connection has been configured (a router
1486 configuration that we are initiating). If there is not, we
1487 will assume that there is only two routers in the SILC network
1488 and we will use the incoming router connection as our primary
1489 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1491 * Changed the order of the broadcasting. Broadcast _after_ the
1492 packet has been processed not before. Affected file is
1495 * Fixed a [ClientConnection] parsing bug. The port was never
1496 parsed correctly thus resulting to port 0. Affected file
1497 silcd/serverconfig.c.
1499 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1500 argument and did not set the broadcast packet flag. Affected
1501 file silcd/packet_send.c. Fixed same bug in the function
1502 silc_server_send_notify as well.
1504 * If we receive NEW_ID packet for our own ID in the server, ignore
1507 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1511 * Removed the nickname from the Private Message Payload.
1512 Updated the code and the protocol specs.
1514 * Updated protocol specs for submitting to the IETF.
1516 * Tweaked the Random Number Generator a bit. Affected file
1517 lib/silccrypt/silcrng.c. Exported a new function
1518 silc_rng_[global]_add_noise which can be used to add more
1521 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Do not parse packets with different timeout when protocol
1524 is active -> may cause problem with rekey. Affected file
1527 * When server receives signoff notify it must not create
1528 new channel key if the client is on any channels since the
1529 sender of the signoff notify will create it.
1531 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Added printing of error messages during SKE protocol from the
1534 failure packet sent by server during SKE. Affected file
1537 * Removed the client's failure_callback handling with timeout
1538 and handle it immediately when received.
1540 * The SKE library returned wrong type in SUCCESS and FAILURE
1541 packets. They must be 32 bit MSB not 16 bit MSB.
1543 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1545 * Ok, rewrote the logic of the re-key and now it seems to work.
1546 I tested it on high traffic with frequent re-keys without
1547 problems. Added hmac_receive (and renamed hmac to hmac_send)
1548 in SilcClientConnection in lib/silcclient/client.h and
1549 in SilcIDListData in silcd/idlist.h. Also, removed the
1550 SilcPacketParserContext's cipher and hmac fields as they are
1551 not needed anymore and actually caused some problems when
1552 the ciphers and hmac's changed underneath the packet parser.
1554 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * If re-key protocol is active then process the incoming packets
1557 synchronously since we must assure that icoming packets encrypted
1558 with the old key is processed before the new keys is set to
1559 use. This is true other packets than for REKEY packets.
1560 Affected file silcd/server.c. The same was done to client library
1561 as well, affected file lib/silcclient/client.c.
1563 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Fixed bug in client and server to accept the force send if
1566 the packet is send from silc_[server/client]_packet_process
1567 function. Otherwise the packets are never delivered, oops.
1569 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Disable force sending of packets when REKEY protocol is active.
1572 We must assure that no packet is sent directly when rekey is
1573 performed. All packets must be sent through packet queue.
1574 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1575 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1576 function is silc_[server/client]_packet_send_real to check
1579 * Replaced the SIM paths from example config files to
1580 /usr/local/modules. Also, make install creates now
1581 /usr/local/silc/logs directory to hold all the SILC server
1584 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Made the configure.in.pre work on Solaris. Patch by salo.
1588 * Made all ciphers compatible with non-x86 machines. Defined
1589 CBC mode macros into lib/silccrypt/ciphers_def.h.
1591 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Fixed the make install.
1595 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * When MAC computation fails the silc_packet_decrypt returned 0
1598 even though it was supposed to return -1. Fixed this. The
1599 affected file is lib/silccore/silcpacket.c.
1601 * Do not replace the config files in /etc/silc (in make install)
1602 if they already exist. Affected file ./Makefile.am.
1604 * Do not send re-key packets immediately but through packet queue.
1605 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1607 * Changed silc_net_check_host_by_sock to return FALSE if the
1608 IP/DNS could not be resolved. Though, it returns the IP address
1609 now even if it could not resolve it (but returns also FALSE).
1610 Affected file lib/silcutil/silcnet.[ch].
1612 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Added silc_pkcs_decode_identifier to decode the public key's
1615 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1616 Added also silc_pkcs_free_identifier. Added also new context
1617 SilcPublicKeyIdentifier.
1619 * Added -S option to the silc client. It is used to dump the
1620 contents of the specified public key file.
1622 * Changed the PKCS api to return the public key length when
1623 setting the public key.
1625 * Fixed a fatal bug in the public and private key file loading.
1626 Affected file lib/silccrypt/silcpkcs.c.
1628 * Execute the packet parsing for client with zero (0) timeout
1629 if the protocol is active. Affected file silcd/server.c.
1631 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Made the key generation options to the silcd program. Added
1634 -C option, equivalent to client's option.
1636 * Added new [ServerKeys] config section to the server. It
1637 configures the server's public and private key.
1639 * Defined generic Public Key Payload into the protocol
1640 specification to send specific type of public keys and
1643 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1644 public key or certificate.
1646 * Implemented the GETKEY command to the server and to the
1647 client library and on user interface.
1649 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Made preliminary `make install' work.
1653 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Added SilcServerRekey context into silcd/idlist.h.
1657 * Added the PFS support as defined in the specification to the
1658 SKE protocol. Affected files lib/silcske/*.c.
1660 * Added `ske_group' field to the SilcServerRekey context to hold
1661 the number of the SKE group that is used with PFS in re-key.
1662 Affected file silcd/idlist.h.
1664 * Added PFS re-key support to the server. Affected file is
1667 * Added silc_protocol_cancel to cancel execution of the next
1668 state of the protocol. Affected file is
1669 lib/silccore/silcprotocol.[ch].
1671 * Added the re-key support with and without PFS to the client
1672 library. Re-key is performed once in an hour, by default.
1674 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1675 Added silc_client_rekey_callback and silc_client_rekey_final.
1676 Affected files are lib/silcclient/protocol.[ch] and
1677 lib/silcclient/client.[ch].
1679 * Removed the `hmac_key' and `hmac_key_len' fields from the
1680 SilcClientConnection structure; not needed. Affected file is
1681 lib/silcclient/client.h.
1685 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1687 * Do not ask whether user wants to use the negotiated private key
1688 for private messages, just use it. Affected file is
1689 silc/local_command.c.
1691 * Added `send_enc_key' and `enc_key_len' fields to the
1692 SilcIDListData structure since they are needed in the re-key
1693 phase. Affected file is silcd/idlist.[ch].
1695 * Implemented the simple re-key protocol into the server.
1696 Affected files silcd/server.c and silcd/protocol.[ch]. The
1697 re-key will be performed once in an hour, by default.
1699 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1700 Added silc_server_rekey, silc_server_rekey_callback and
1701 silc_server_rekey_final.
1703 * Removed Tunneled flag from the protocol. Updated the code
1704 and the specifications.
1706 * Adde `pfs' field to the SilcIDListData to indicate whether
1707 the PFS is to be performed in the re-key. Affected file is
1710 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1713 int64 of at least the xintXX size. If void * is less that 4
1714 bytes uint32 * will be used. Defined bool as boolean.
1716 * Changed _ALL_ unsigned long and unsigned int to uint32,
1717 unsgined short to uint16 in the source tree.
1719 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1720 not handle clients that has entry->data.registered == FALSE.
1721 They are not in the network anymore. Affected file is
1724 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Implemented the sending of the SERVER_SIGNOFF notify in the
1727 server. Affected file is silcd/server.c.
1729 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1730 Added also silc_notify_payload_encode_args into the
1731 lib/silccore/silcnotify.[ch].
1733 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1734 Affected file silcd/packet_receive.c.
1736 * Implemented the SERVER_SIGNOFF notify handling in the client
1737 library. Affected file lib/silcclient/client_notify.c. Also,
1738 implemnted the printing of the SERVER_SIGNOFF info to the
1739 application. Affected file silc/client_ops.c.
1741 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1742 if the deleting was successful. Affected file silcd/idlist.[ch].
1744 * Added support for public key authentication in the connection
1745 authentication protocol in the client library. Affected file
1746 lib/silcclient/protocol.c.
1748 * Changed the server's silc_idlist_get_clients_by_* interface
1749 to support already allocated array so that new entries may be
1750 added to pre-allocated array. Affected file silcd/idlist.[ch].
1751 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1752 and command replies.
1754 * All command reply functions in the server now calls the
1755 pending command callback even if error occured. This way the
1756 error will be delivered to the client as well. Affected files
1757 silcd/command.c and silcd/command_reply.c.
1759 * Fixed INFO command to return local server's info if no server
1760 was provided. Affected file lib/silcclient/command.c.
1762 * Removed RESTART command for good. Updated the code and the
1765 * Rewrote parts of the task system. It is a bit simpler now.
1766 Removed unsued task priorities. The affected files are
1767 lib/silcutil/silctask.[ch].
1769 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Moved the USERS printing from the library to the application.
1772 Affected files lib/silcclient/command.c and silc/client_ops.c.
1774 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Added channel key re-key support. The re-key is perfomed
1779 only by the router and is done once in an hour. Added `rekey'
1780 field to the SilcChannelEntry in the server. Affected files
1781 silcd/server.c and silcd/idlist.h.
1783 * Added silc_task_unregister_by_context into the file
1784 lib/silcutil/silctask.[ch].
1786 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Added SILC_UMODE_GONE mode to indicate when the client is not
1789 present in the SILC network. Added also support to the local
1790 command AWAY that will set this mode. Added support of showing
1791 "xxx is gone" in WHOIS command. The USERS command shows the
1792 gone status as well.
1794 * Fixed setting server and router operator privileges in the
1795 server's UMODE command. Affected file silcd/command.c.
1797 * Merged the SKE KE1 and KE2 payloads into one payload. The
1798 new KE payload is equivalent to the old KE2 payload.
1800 Cleaned up the SKE Start Payload parsing. It now uses the
1801 simple buffer unformatting to do the parsing. A lot faster
1804 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1805 to the SKE that is used to indicate whether both of the SKE
1806 parties should perform authentication. By default only the
1807 responder performs authentication. By setting this flag also
1808 the initiator must do authentication. By default it is unset
1809 since in normal SKE case, client to server connection, only
1810 the responder should do authentication. When doing SKE between
1811 two clients both should perform authentication. Updated the
1812 code and the protocol specs.
1814 * A little fix to IDENTIFY command in the server. Search the
1815 client first by hash not nickname. Affected file is
1818 * Fixed the silc_client_close_connection to support closing
1819 the client to client connections wihtout deleting too much
1820 data. Affected file lib/silcclient/client.c.
1822 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1823 are received if protocol used to be active but is not anymore
1824 the application would crash due to NULL pointer dereference.
1825 Affected files silcd/server.c and lib/silcclient/client.c.
1827 * Added `hash' field to the SilcClientConnection to include
1828 the hash function negotiated in the SKE protocol.
1830 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1831 to set the channel founder authentication data. A client can
1832 claim the founder rights later by providing the authentication
1833 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1834 This way the channel founder can regain the channel founder
1835 privileges even it is left the channel. This works only on
1836 local server and the client must be connected to the same
1837 server to be able to regain the founder rights. Updated the
1838 protocol specs accordingly.
1840 Added support to the CMODE command in the client to set the
1841 founder auth data. Read the README to see how to set it.
1843 Added support to the CUMODE command to claim the founder
1844 rights. Read the README to see how to do it.
1846 Added support for the founder authentication to the Channel
1847 Entry in the server. Affected file silcd/idlist.h.
1849 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1850 server's CMODE command. Affected file silcd/command.c.
1852 * Added the following new functions into lib/silccore/silcauth.[ch]:
1853 silc_auth_get_method and silc_auth_get_data.
1855 * The server now saves the remote hosts public key to the
1856 SilcIDListData pointer. Affected file silcd/protocol.c.
1858 * The normal server now does not remove the channel entry from
1859 the cache if the founder authentication data is set. It used
1860 to remove it if the founder was the last one on the channel on
1861 the server and left the channel. The auth data is saved and
1862 if the channel is re-joined later the old entry is used with
1863 the old auth data. Affected files silcd/command_reply.c and
1866 * Removed the `pkcs' field from the SilcIDListData structure
1867 in the server; it is not used. Affected file silcd/idlist.h.
1869 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1871 * Fixed packet processing on slow links. Partial packets were
1872 never re-processed because the incoming data buffer was cleared
1873 by the application. Application must not directly clear the
1874 sock->inbuf, the packet processing routines handle it. Fixed
1875 this in client library and in server.
1877 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Fixed the WHOIS and IDENTIFY send reply function to really
1880 check whether to send list or just one entry. Affected file
1883 * Cleaned up the LEAVE command's channel key distribution. The
1884 affected file silcd/command.c.
1886 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1887 can enforce the channel mode as well. In that case the ID
1888 includes the ID of the server. The code now enforces the
1889 mode change if the router have different mode than the server.
1891 * The notify client operation with CMODE_CHANGE notify can now
1892 return NULL client_entry pointer if the CMODE was not changed
1893 by client. Application must check for this.
1895 * Added <Server ID> argument to INFO command to support server
1896 info fetching by Server ID.
1898 * Added silc_server_announce_get_channel_users to get assembled
1899 packets of channel users of the specified channel. Affected
1900 file silcd/server.[ch].
1902 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1903 was freed underneath the ID Cache.
1905 * Re-announce clients when the server received CHANNEL_CHANGE
1906 notify from the router. Affected file silcd/packet_send.c.
1908 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1911 crashed since it did not handle the fact that there is no cipher
1912 called "3" and didn't check the error condition. Now fixed.
1914 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1915 flag. It can be used to send message requests.
1917 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Implemented the RESTART command in the client.
1921 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1922 notice type messages. Added notice printing to the user
1925 * The channel keys are not re-generated if the channel's mode
1926 is PRIVKEY, ie private key on the channel exists. Affected
1927 files silcd/server.c and silcd/command.c.
1929 * Fixed a little bug in channel message delivery when channel
1930 private keys are set in the server. Affected file is
1931 silcd/packet_send.c.
1933 * Changed the setting on channel->on_channel = TRUE from the
1934 silc_client_save_channel_key to the JOIN command reply. The
1935 key payload is not received if the private channel key is set.
1936 Affected file lib/silcclient/command_reply.c and the
1937 lib/silcclient/client_channel.c.
1939 * When the CMODE_CHANGE notify is sent and the channel private
1940 key mode is removed the channel key must be re-generated in
1941 other cells as well. Added this support for the router in the
1942 silcd/packet_receive.c.
1944 * Added new local command NOTICE to send notice message on
1945 channel. Affected file silc/local_command.[ch].
1947 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Added new local command ME to the client. It is used to send
1950 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1951 some action. Affected file silc/local_command.[ch].
1953 * Changed channel_message and private_message client operations
1954 to deliver the message flags to the application. Added also
1955 the `flags' arguments to the silc_client_send_channel_message
1956 and silc_client_send_private_message functions. Affected file
1959 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Redefined the Private Message Payload to support private message
1962 keys and to support the new private message flags. Updated
1963 the protocol specs. Flags makes it possible to have for example
1964 CTCP style messages.
1966 * Added new type SilcPrivateMessagePayload and defined an API
1967 for it in the lib/silcclient/silcprivate.[ch].
1969 * Tested private message private keys successfully. Tested the
1970 private message key set, unset and list commands with the new
1973 * Redefined the Channel Message Payload to include the channel
1974 message flags (equal with private message flags) to support
1975 for example CTCP style messages.
1977 * Defined some of the message (for channel and private message)
1978 flags. Updated the protocol specs and added the flags to the
1979 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1981 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Added SilcKeyAgreementStatus type to the key agreement routines
1984 to indicate the current status and error if one occured.
1985 The status types are defined in the lib/silcclient/silcapi.h.
1987 * Added new local command KEY that is used to set and unset private
1988 keys for channels, set and unset private keys for private messages
1989 with remote clients and to send key agreement requests and
1990 negotiate the key agreement protocol with remote client. The
1991 key agreement is supported only to negotiate private message keys,
1992 it currently cannot be used to negotiate private keys for channels,
1993 as it is not convenient for that purpose.
1995 * Fixed a minor pending callback setting bug in the function
1996 silc_client_get_client_by_id_resolve, now the function works.
1997 Affected file lib/silcclient/idlist.c.
1999 * Added function silc_net_get_local_port to get local bound
2000 port by socket. Added to lib/silcutil/silcnet.[ch].
2002 * Added `sockets' and `sockets_count' fields to the SilcClient
2003 object. They hold the sockets of the listenning sockets in
2004 the client. Listenning sockets may be for example the key
2005 agreement server. Affected file lib/silcclient/client.[ch].
2006 Added functions the silc_client_add_socket and the
2007 silc_client_del_socket. They are exported to the application
2010 * Added ~./silc/clientkeys to support other client's public keys.
2012 * Renamed verify_server_key client operation to verify_public_key
2013 and added one argument to indicate the type of the connection
2014 (server, client etc.).
2016 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Added silc_server_connection_auth_request to handle the
2019 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2020 silcd/packet_receive.[ch].
2022 * Added silc_server_send_connection_auth_request into the
2023 silcd/packet_send.c to send the connection auth request packet.
2025 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2028 * Fixed the public key authentication in responder side in the
2029 server. The `auth_data' pointer includes the SilcPublicKey
2030 not the path to the public key. Affected file silcd/protocol.c.
2032 * Implemented the public key authentication in the initiator side
2033 in the server. Affected file silcd/protocol.c.
2035 * Removed the [RedirectClient] config section from the server
2036 configuration. Is not needed and I don't want to implement it.
2038 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Cleaned up the CMODE command in the server. It now works
2041 correctly and supports all the modes defined in the protocol.
2042 Affected file is silcd/command.c.
2044 * Added `hmac_name' field to the SilcChannelEntry in the server
2045 to hold the default HMAC of the channel. It can be set when
2046 creating the channel (with JOIN command). Affected files
2049 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2050 type to indicate the change of the current cipher and hmac
2051 on the channel. Client can safely ignore the <cipher> argument
2052 (if it chooses to do so) since the CHANNEL_KEY packet will
2053 force the channel key change anyway. The <hmac> argument is
2054 important since the client is responsible of setting the new
2055 HMAC and the hmac key into use.
2057 * Fixed the CMODE command in the client library as well.
2059 * Tested CMODE command in router environment successfully.
2061 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Show the version of the remote client (or server) when connecting
2064 to the server. It is logged to the log file. Affected file
2065 is silcd/protocol.c.
2067 * Fixed the KILLED notify handling in the client library. The
2068 client must be removed from all channels when receiving the
2071 Also, do not remove the client entry when giving the KILL
2072 command but when the KILLED notify is received.
2074 * Removed silc_idlist_find_client_by_nickname from the server.
2075 Not needed anymore. Affected files silcd/idlist.[ch].
2077 * Implemented the CHANNEL_CHANGE notify type handling to the
2078 server. Affected file silcd/server.c.
2082 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added silc_server_send_notify_invite to send the INVITE
2085 notify between routers.
2087 * Implemented the INVITE command correctly to the server.
2089 * Implemented the INVITE notify type handling in the server.
2091 * Implemented the INVITE command to the client library and on the
2094 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Added function silc_server_get_client_resolve to find the
2097 client entry by ID from all ID lists and then resolve it
2098 (using WHOIS) if it cannot be found. Affected file is
2101 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Implemented the BAN command to the client library.
2105 * The JOIN command in the server now checks the invite list
2108 * Changed the silc_command_reply_payload_encode_va and the
2109 silc_command_payload_encode_va to support that if argument is
2110 NULL it ignores and checks the next argument. Affected file
2111 lib/silccore/silccommand.c.
2113 * Added silc_server_send_notify_ban to send the BAN notify
2114 type between routers.
2116 * Chaned the silc_notify_payload_encode to support that if
2117 argument is NULL it ignores and checks the next argument.
2118 Affected file lib/silccore/silcnotify.c.
2120 * Tested ban lists in router environment successfully.
2122 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Implemented BAN command to the server, in silcd/command.[ch].
2126 * Removed the BAN and INVITE_LIST modes from the CMODE command
2129 * Added function silc_string_match to regex match two strings.
2130 Affected files lib/silcutil/silcutil.[ch].
2132 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Redefined parts of the SilcChannelEntry in the server to support
2135 the new ban and invite lists.
2137 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Redefined the INVITE command. The same command can be used to
2140 invite individuals to the channel but also to manage the invite
2141 list of the channel (to add to and remove from the invite list).
2142 Updated the protocol specs.
2144 * Added new command SILC_COMMAND_BAN that can be used to manage
2145 the ban list of the channel. Updated the protocol specs.
2147 * Removed the channel modes: the SILC_CMODE_BAN and the
2148 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2149 in the CMODE command. The equivalent features are now available
2150 using INVITE and BAN commands. Updated the protocol specs.
2152 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2153 in the network about change in the current ban list. The notify
2154 type is not used by the client.
2156 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2157 support the invite lists.
2159 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Added new function silc_string_regexify that converts string
2162 including wildcard characters into regex string that can
2163 be used by the GNU regex library. Added into the file
2164 lib/silcutil/silcutil.[ch].
2166 Added silc_string_regex_combine to combine to regex strings
2167 into one so that they can be used as one regex string by
2168 the GNU regex library. Added into the file
2169 lib/silcutil/silcutil.[ch].
2171 Added silc_string_regex_match to match two strings. It returns
2172 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2174 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Imported GNU regex to the soruce tree into lib/contrib.
2177 Fixed some compiler warning from the regex.c.
2179 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2181 * Fixed MOTD command in the server to work in router environment.
2183 * Fixed the MOTD command in the client library to support
2184 the server argument in the command.
2186 * Added `nickname_len' argument to the silc_idlist_add_client
2187 in the server, as the `nickname' argument may be binary data
2190 * Added silc_idlist_get_channels to return all channels from
2193 * Implemented LIST command to the server. Affected file is
2196 * Implemented the LIST command to the client library and on the
2199 * Added [<user count>] argument to the LIST command reply.
2200 With private channels the user count is not shown.
2202 * Updated TODO and README.
2204 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * The client entry's data.registered must be TRUE even with
2207 global client entry on global client list. The data.registered
2208 is used to check whether the client is anymore in the network,
2209 for example with WHOWAS command so it must be valid.
2211 * Fixed the WHOWAS command in the server. It now actually works
2212 in router environment. Added function into silcd/command_reply.c
2213 silc_server_command_reply_whowas_save.
2215 * Added silc_idlist_purge function to the silcd/idlist.c
2216 to periodically purge the ID Cache.
2218 * Fixed INFO command in the server. It works now in router
2219 environment. Added <server name> argument to the INFO command
2220 reply. Updated the protocol specs.
2222 * Fixed minor bug in silc_idcache_purge to not purge if the
2223 expire value is zero.
2225 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2226 they were buggy because of the WHOWAS information.
2228 * Fixed local command MSG to handle the async resolving of
2229 the remote client properly. It used to fail the first MSG.
2230 Affected file silc/local_command.c.
2232 * Added `data_len' field to SilcIDCache context.
2234 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Update TODO. Todo in commands in the server.
2238 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2241 used by routers as broadcast packet to inform other routers
2242 about the changed user mode.
2244 Implemented the notify handling in the server. Affected file is
2245 silcd/packet_receive.c. Added the function
2246 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2248 * Added new generic Channel Payload and deprecated the New Channel
2249 Payload. The New Channel Payload is now the generic Channel
2252 * Added new argument `mode' to the silc_server_send_new_channel
2253 as it is required in the Channel Payload now.
2255 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2256 and created a new and real SilChannelPayload to represent the
2257 new generic Channel Payload. Implemented the encode/decode
2258 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2260 * Added silc_server_get_client_channel_list to return the list
2261 of channels the client has joined for WHOIS command reply.
2262 Affected file silcd/server.[ch].
2264 * Implemented the channel list sending in the WHOIS command reply
2265 in server and in the client.
2267 Implemented the channel list displaying on the user interface
2268 as well. Affected file silc/client_ops.c.
2270 * Added silc_channel_payload_parse_list to parse list of Channel
2271 Payloads. It returns SilcDList list of SilcChannelPayloads.
2272 Client for example can use this function to parse the list of
2273 channels it receives in the WHOIS command reply. The caller
2274 must free the list by calling silc_channel_payload_list_free.
2275 Affected files lib/silccore/silcchannel.[ch].
2277 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Added one new argument <user mode> to the WHOIS command reply
2280 to return the mode of the user in SILC. Updated the protocol
2283 Implemented it to the server and client.
2285 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Fixed the mode printing on the user interface on joining.
2288 Affected file silc/client_ops.c.
2290 * Implemented the UMODE command and user modes in general to the
2291 client library and to the user interface.
2293 * Implemented the UMODE command to the server.
2295 * The server now sends UNKNOWN_COMMAND error status if client sends
2296 unknown command. Affected file silcd/command.c.
2298 * All server commands now handle the command identifier the right
2299 way when sending the command reply to the client. The client can
2300 use to identify the command replies with the identifier.
2302 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Added silc_server_get_client_route to resolve the route to
2305 the client indicated by the client ID. Affected file is
2308 * Added silc_server_relay_packet as general function to relay
2309 packet to arbitrary destination. This deprecates functions
2310 like _send_private_message_key, _relay_notify etc. Affected
2311 file is silcd/packet_send.[ch].
2313 Removed silc_server_send_key_agreement,
2314 silc_server_send_private_message_key and
2315 silc_server_packet_relay_notify functions from the file
2316 silcd/packet_send.[ch].
2320 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2321 server. Affected file silcd/packet_receive.[ch].
2323 * Implemented the KILL command to the client. Implemented the
2324 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2325 Affected files lib/silcclient/command[_reply].c and
2326 lib/silcclient/client_notify.c. Implemented the KILL notify
2327 printing in the user inteface.
2329 * Fixed a lot silc_parse_nick memory leaks from the client
2330 library in the file lib/silcclient/command.c.
2332 * Changed the silc_server_send_notify_on_channels's `sender'
2333 argument from SilcSocketConnection to SilcClientEntry to
2334 check the sender as entry and not as connection object and not
2335 to send to the client provided as argument. The affected file
2336 is silcd/packet_send.[ch].
2338 * The notify packets that are destined directly to the client used
2339 to not to be processed by the server. Now changed that and the
2340 server processes all notify packets. After relaying the packet
2341 to the client the notify packet is processed in the server.
2343 * The silc_server_free_client_data now checks whether there is
2344 pending outgoing traffic for the client and purges the data to
2345 the network before removing the client entry.
2347 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2350 an client is killed from the SILC Network. Updated the protocol
2353 Added new function silc_server_send_notify_killed to the
2354 silcd/packet_send.[ch].
2356 * Added function silc_server_packet_relay_notify to relay notify
2357 packets that are destined directly to a client. In this case
2358 the server does not process the notify packets but merely relays
2359 it to the client. Affected file silcd/packet_send.[ch].
2361 Added also silc_server_packet_process_relay_notify to check
2362 whereto relay the notify. Affected file is
2363 silcd/packet_receive.[ch].
2365 * Implemented the KILL command to the server.
2369 * Added the backup schema desgined last fall to the protocol
2370 specs for everyone to see. The specification is in the
2371 *-spec-xx.txt draft and the packet type definitions for the
2372 backup routers is in *-pp-xx.txt draft. Thusly, added also
2373 new packet type SILC_PACKET_CELL_ROUTERS.
2375 * A big security problem in the implementation discovered. The
2376 signoff of an client did not cause new channel key generation
2377 which it of course should've done. The channel keys must be
2378 always re-generated when client leaves (or signoffs) the channel.
2379 The silc_server_remove_from_channels funtion now handles
2380 the channel key re-generation.
2382 * Added `sender' argument to the silc_server_send_notify_on_channels
2383 to not to send the client provided as argument. Affected file
2384 silcd/packet_send.[ch].
2386 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Implemented OPER and SILCOPER commands into the server and
2391 * Added silc_auth_verify and silc_auth_verify_data to verify
2392 the authentication directly from the authentication payload.
2393 It supports verifying both passphrase and public key based
2394 authentication. Affected file lib/silccore/silcauth.[ch].
2396 * Added `hash' field to the SilcIDListData structure. It is the
2397 hash negotiated in the SKE protocol. Affected file is
2400 * Slight redesigning of the SilcAuthPayload handling routines.
2401 Do not send SilcPKCS but SilcPublicKey as argument.
2403 * Implemented the public key authentication support to the
2404 serverconfig. The public key is loaded from the provided path
2405 and saved as authentication data to void * pointer. Thus,
2406 changed the unsigned char *auth_data to void *auth_data;
2408 * Fixed SHUTDOWN command to send the reply before the server
2409 is shutdown. :) Affected file silcd/command.c.
2411 * Fixed fatal bug in CONNECT command. The hostname was invalid
2412 memory and server crashed. Affected file silcd/command.c.
2414 * Fixed fatal bug in CLOSE command. The server_entry became
2415 invalid but was referenced later in the command. Affected file
2418 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Fixed fatal bug in failure packet handling. Server ignored
2421 the failure and thus crashed when it came.
2425 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2427 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2428 that the command may be executed only once in (about) 2 seconds.
2429 The old SILC_CF_LAG flag is same but allows command bursts up
2430 to five before limiting.
2432 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2433 server code. Various commands now includes the CF_LAG_STRICT
2434 flag to disallow any kind of miss-use of the command.
2436 * Fixed the silc_buffer_unformat to not to allocate any data
2437 if the length of the data is zero. It used to allocate the
2438 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2440 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Changed the format of AdminConnection configuration section
2443 in the server. Added username of the admin to the format.
2444 Affected files silcd/serverconfig.[ch].
2446 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2447 to return admin configuration data by host, username and/or
2450 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Implemented WHOWAS command to the server. Added the functions:
2454 silc_server_command_whowas_parse,
2455 silc_server_command_whowas_send_reply,
2456 silc_server_command_whowas_from_client and
2457 silc_server_command_whowas_from_server
2459 * Added <Client ID> argument to the WHOWAS command reply. Updated
2460 the protocol specs accordingly.
2462 * Implemented WHOWAS command and command_reply to the client
2465 Implemented the WHOWAS printing on the user interface.
2467 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Added new argument to the WHOWAS command reply, the real name.
2470 It is an optional argument. Updated the protocol specs.
2472 * Added SilcIDCacheDestructor callback that is registered when
2473 the SilcIDCache is allocated. The callback is called when
2474 an cache entry in the ID Cache expires, or is purged from the
2475 cache. Added into lib/silccore/idcache.[ch].
2477 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2478 to destruct the client entries when the cache entry expires.
2479 Other ID Cache's in server and in the client library ignores
2482 * If the ID Cache entry's `expire' field is zero then the entry
2483 never expires. Added boolean `expire' argument to the
2484 silc_idcache_add function in the lib/silccore/idcache.[ch].
2485 If it is TRUE the default expiry value is used.
2487 * Added silc_server_free_client_data_timeout that is registered
2488 when client disconnects. By default for 5 minutes we preserve
2489 the client entry for history - for WHOWAS command.
2491 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Added support to the server to enforce that commands are not
2494 executed more than once in 2 seconds. If server receives
2495 commands from client more frequently, timeout is registered
2496 to process the commands. Affected file silcd/command.c.
2497 Added new function silc_server_command_process_timeout.
2499 * Changed NICK_NOTIFY handling in client library to check that
2500 if the client's nickname was changed, so there is no need to
2501 resolve anything from the server.
2503 * Removed error printing from the WHOIS and IDENTIFY commands.
2504 If error occurs then it is ignored silently in the client library.
2505 The application, however, may map the received error to
2506 human readable error string. The application currently maps
2507 the NO_SUCH_NICKNAME error to string.
2509 * Made the command status message public to the application. Moved
2510 them from lib/silcclient/command_reply.c to
2511 lib/silcclient/command_reply.h. The application can map the
2512 received command status to the string with the
2513 silc_client_command_status_message function.
2515 * Added check to the server to check that client's ID is same
2516 as the Source ID in the packet the client sent. They must
2519 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Added dist-bzip hook to the Makefile.am to make bzip2
2522 compressed distributions.
2524 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Server now enforces the maximum length for the nickname and
2527 the channel as protocol specification dictates. 128 bytes for
2528 nickname and 256 bytes for channel name.
2530 * Moved the WHOIS printing to the application. The client libary
2531 does not print out the WHOIS information anymore, the application
2532 must do it. Renamed silc_client_command_reply_whois_print to
2533 the silc_client_command_reply_whois_save.
2535 The client's idle time is also sent to the application now, and
2536 the idle is shown on screen.
2538 * Added silc_client_command_reply_identify_save to save the
2539 received IDENTIFY entries.
2541 * Do not check for channel private keys in message sending and
2542 reception if the channel does not have the PRIVKEY mode set.
2543 Affected file lib/silclient/client_channel.c.
2545 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2548 just surfaced after chaning the JOIN procedure.
2550 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added silc_client_get_clients_by_list to get client entries
2553 from Client ID list, that is returned for example by JOIN
2554 and USERS command replies. The application should use this
2555 function for example when JOIN command reply is received to
2556 resolve the clients already on the channel (library does not
2557 do that anymore as USERS command reply is not used in the JOIN
2558 procedure anymore). Affected files lib/silcclient/silcapi.h and
2559 lib/silcclient/idlist.c.
2561 * JOIN command reply and USERS command reply returns now SilcBuffer
2562 pointers instead of unsigned char pointers when returning
2563 the client list and mode list.
2565 * Added <Client ID> argument to the JOIN command reply, mainly
2566 for the server to identify for which client the command was
2567 originally sent. Updated protocol specs accordingly.
2569 * Added SilcDlist private_key pointer to the SilcChannelEntry
2570 in the client to support the channel private keys. Affected
2571 file is lib/silcclient/idlist.h.
2573 * Added SilcChannelPrivateKey argument to the function
2574 silc_client_send_channel_message so that application can choose
2575 to use specific private ke if it wants to. If it is not provided,
2576 the normal channel key is used, unless private keys are set.
2577 In this case the first (key that was added first) is used
2578 as the encryption key.
2580 * Implemented the support for channel private key handling.
2581 Implemented the following functions:
2583 silc_client_add_channel_private_key,
2584 silc_client_del_channel_private_keys,
2585 silc_client_del_channel_private_key,
2586 silc_client_list_channel_private_keys and
2587 silc_client_free_channel_private_keys
2589 Affected file lib/silcclient/client_channel.c.
2591 * Added the support for the private keys in the channel message
2592 sending and encryption and in the message reception and
2593 decryption. Affected funtions are
2594 silc_client_send_channel_message and silc_client_channel_message.
2596 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Added SKE's key verify callback to the client library's
2599 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2601 * Removed the statement that server (or router) must send USERS
2602 command reply when joining to the channel so that the client
2603 knows who are on the channel. Instead, the client list and
2604 client's mode list is now sent in the JOIN command reply to the
2605 client who joined channel. This is better solution.
2607 * Added function silc_server_get_users_on_channel and function
2608 silc_server_save_users_on_channel to the silcd/server.[ch].
2610 * Removed function silc_server_command_send_users from the
2613 * Do not show topic on the client library anymore. The topic is
2614 sent in the command reply notify to the application and the
2615 application must show the topic now.
2617 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Added client searching by nickname hash into the IDENTIFY and
2620 WHOIS commands in the server as they were clearly missing from
2621 them. Affected file is silcd/command.c.
2623 * Fixed a bug in private message receiving in the client library.
2624 The remote ID was freed and it wasn't supposed, now it is
2627 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Minor fix to the channel payload; allocate the data area, as it
2630 needs to be of specific length.
2632 * If the key agreement port is zero then the operating
2633 system will define the bound port. Affected files are
2634 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2636 * Added new function silc_channel_payload_decrypt into the file
2637 lib/silccore/silcchannel.[ch].
2639 * Moved the channel message etc, check from silc_packet_decrypt
2640 to applications. The library calls now a generic
2641 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2642 when the packet is either normal or special. This was done to
2643 allow more wide range of checking that was not allowed when
2644 the code was in library. Now applications can do virtually any
2645 checks to the packet and return to the library the decision how
2646 the packet should be processed. Affected files are
2647 lib/silccore/silcpacket.[ch].
2649 Added silc_server_packet_decrypt_check to the server and
2650 silc_client_packet_decrypt_check to the client library.
2652 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2653 to send with specified source and destination information.
2655 * Channel message delivery between routers was broken after the
2656 channel key distribution was fixed earlier. The channel key
2657 was used be to distributed to other routers as well which is not
2658 allowed by the protocol. Now this is fixed and channel keys
2659 really are cell specific and the channel message delivery between
2660 routers comply with the protocol specification.
2662 * Fixed various commands in server to check also the global list
2663 for the channel entry and not just the local list. The affected
2664 file silcd/command.c.
2666 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Added assert()s to buffer formatting and unformatting routines
2669 to assert (if --enable-debug) when error occurs. Affected
2670 file: lib/silcutil/silcbuffmt.c.
2672 * Changed to auto-reconnect to check whether the remote host is
2673 router and register the re-connect timeout if it is. It used
2674 to check that whether we are normal server, but router must do
2675 auto-reconnect with another router as well. Affected file
2678 * Removed the [<key len>] option from CMODE command as the cipher
2679 name decides the key length, nowadays. See the defined ciphers
2680 from the protocol specification.
2682 * Added [<hmac>] option to the CMODE command to define the HMAC
2683 for the channel. Added SILC_CMODE_HMAC channel mode.
2685 * Added [<hmac>] option for the JOIN command so that user can
2686 select which HMAC is used to compute the MACs of the channel
2689 * Added Hmac field to the Channel Message Payload. The integrity
2690 of plaintext channel messages are now protected by computing
2691 MAC of the message and attaching the MAC to the payload. The
2692 MAC is encrypted. Now, it is clear that this causes some
2693 overhead to the size of the packet but rationale for this is that
2694 now the receiver can verify whether the channel message decrypted
2695 correctly and also when private keys are set for the channel the
2696 receiver can decrypt the packet with several keys and check from
2697 the MAC which key decrypted the message correctly.
2699 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2700 lib/silccrypt/silccipher.[ch].
2702 * Added silc_hash_len to return the digest length into the
2703 lib/silcrypt/silchash.[ch].
2705 * Rewrote parts of Silc Channel Payload interface in the
2706 lib/silccore/silcchannel.[ch]. The encode function now also
2707 encrypts the packet and parse function decrypts it.
2709 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Fixed a minor formatting bug in the SKE's key material processing.
2712 It actually might have processed the keys wrong way resulting
2715 * Redefined the mandatory HMAC algorithms and added new algorithms.
2716 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2717 and hmac-md5 truncated to 96 bits. The mandatory is now
2718 hmac-sha1-96. Rest are optional (including the one that used
2719 to be mandatory). Rationale for this is that the truncated HMAC
2720 length is sufficient from security point of view and can actually
2721 make the attack against the HMAC harder. Also, the truncated
2722 HMAC causes less overhead to the packets. See the RFC2104 for
2725 * Added new [hmac] configuration section. The SKE used to use
2726 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2727 is of course wrong. The official names that must be proposed in
2728 the SKE are the ones defined in the protocol specification
2729 (hmac-sha1-96 for example). The user can configure any hmac
2730 using any hash function configured in the [hash] section. At
2731 least, the mandatory must be configured.
2733 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2735 * Added HMAC list to the SKE proposal list. It has now both
2736 hash algorithm list and HMAC list. This makes the protocol
2737 incompatible with previous versions. The SKE now seems to work
2738 the way it is supposed to work, for the first time actually.
2740 * Defined plain Hash algorithms to the protocol specification.
2743 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Implemented support for key agreement packets into the server.
2746 Added functions silc_server_key_agreement and
2747 silc_server_send_key_agreement. Other than these functions,
2748 server has nothing to do with this packet.
2750 * Added support for private message key packets into the server.
2751 Added functions silc_server_private_message_key and
2752 silc_server_send_private_message_key.
2756 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2757 called in the protocol's final callback instead in the END
2758 protocol state. This makes a little more sense and in the same
2759 time in client we can use the same protocol routines for normal
2760 key exchange and to key agreement packet handling as well.
2762 * Added to both client's and server's KE protocol context the
2763 SilcSKEKeyMaterial pointer to save the key material. We will
2764 bring the key material to the protocol's final callback by doing
2765 this. The final callback must free the key material.
2767 * Added SKE's packet_send callback into client's KE protocol
2768 context so that the caller can choose what packet sending function
2769 is used. This way we can use different packet sending when
2770 doing normal SKE when doing key agreement packet handling (in
2771 the key agreement packet handling we do not want to encrypt
2774 * Implemented the responder side of the key agreement routines
2775 in the client. The client can now bind to specified port and
2776 accept incoming key negotiation. The key material is passed
2777 to the application after the protocol is over.
2779 * Implemented the processing of incoming Key Agreement packet
2780 in the client. Added function silc_client_key_agreement to
2783 * Implemented the intiator side of the key agreement routines
2784 in the client. The client can now initiate key agreement with
2785 another remote client. The key material is passed to the
2786 application after the protocol is over.
2788 * Created client_keyagr.c to include all the key agreement
2791 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2792 SILC_TASK_CALLBACK except that it is not static.
2794 * Created client_notify.c and moved the Notify packet handling
2795 from the client.[ch] into that file.
2797 * Created client_prvmsg.c and moved all private message and
2798 private message key routines from the client.[ch] into that file.
2800 * Create client_channel.c and moved all channel message and
2801 channel private key routines from the client.[ch] into that file.
2803 * Changed silc_client_get_client_by_id_resolve to resolve with
2804 WHOIS command instead of IDENTIFY command, in the file
2805 lib/silclient/idlist.c.
2807 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Implemented the SKE's responder side to the Client library.
2811 * When FAILURE is received to the protocol do not trust it
2812 blindly. Register a timeout to wait whether the remote closes
2813 the connection as it should do it, only after that process the
2814 actual failure. This was changed to both client and server.
2816 * Added client_internal.h to include some of the structures
2817 there instead of client.h in lib/silcclient/.
2819 * Added function silc_task_unregister_by_callback to unregister
2820 timeouts by the callback function.
2822 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Some "Incomplete WHOIS info" errors has been appearing on the
2825 log files. Took away the entry->userinfo check from WHOIS
2826 reply sending. The entry->userinfo is now " " if client did not
2827 provide one. I thought this was fixed earlier but something
2828 is wrong still. Let's see if the error still appears.
2830 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Fixed a minor bug in the login when the channel key is
2833 re-generated in the server. It used to generate the key in
2834 wrong order and thus caused problems in the channel traffic.
2836 * Fixed a minor bug in channel key distsribution after
2837 KICK command. The key was not sent to the router even though
2840 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Added silc_ske_process_key_material_data as generic routine
2843 to process any key material as the SILC protocol dictates. The
2844 function is used by the actual SKE library but can be used by
2845 applications as well. This relates to the private message keys
2846 and the channel private keys since they must be processed the
2847 same way the normal SILC session keys. The protocol dictates
2848 this. Affected files: lib/silcske/silcske.[ch].
2850 Added also silc_ske_free_key_material to free the
2851 SilcSKEKeyMaterial structure.
2853 * Defined silc_cipher_set_key function to set the key for
2854 cipher without using the object's method function. The affected
2855 files: lib/silccrypt/silccipher.[ch].
2857 * Implemented silc silc_client_add_private_message_key,
2858 silc_client_add_private_message_key_ske,
2859 silc_client_del_private_message_key,
2860 silc_client_list_private_message_keys and
2861 silc_client_free_private_message_keys functions in the
2864 Added functions silc_client_send_private_message_key to send
2865 the Private Message Key payload and silc_client_private_message_key
2866 to handle incoming Private Message Key payload.
2868 * Added Cipher field to the Private Message Key payload to set
2869 the cipher to be used. If ignored, the default cipher defined
2870 in the SILC protocol (aes-256-cbc) is used.
2872 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Removed lib/silcclient/ops.h file.
2876 Redefined parts of the SILC Client Library API. Created new
2877 file silcapi.h that deprecates the ops.h file and defines the
2878 published Client Library API. Defined also private message key
2879 API and channel private key API into the file.
2881 This is the file that the application must include from the
2882 SILC Client Library. Other files need not be included by
2883 the application anymore.
2885 * Added new key_agreement client operation callback and also
2886 defined the Key Agreement library API for the application.
2888 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2891 is used by clients to request key negotiation between another
2892 client in the SILC network. If the negotiation is started it
2893 is performed using the SKE protocol. The result of the
2894 negotiation, the secret key material, can be used for example
2895 as private message key.
2897 Implemented the Key Agreement payload into the files
2898 lib/silccore/silauth.[ch].
2900 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Redefined ciphers for the SILC protocol. Added some new ciphers
2903 and defined the key lengths for the algorithms. Changed the
2904 code accordingly. The default key length is now 256 bits.
2906 * Fixed SKE key distribution function silc_ske_process_key_material
2907 when the key length is more than 128 bits. The default key
2908 length in SILC is now 256 bits.
2910 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2911 to indicate unsupported algorithm.
2913 * Renamed rijndael.c to aes.c and all functions as well.
2915 * Fixed a long standing channel key setting bug in client library.
2916 Weird that it has never surfaced before.
2918 * Fixed bug in channel deletion. If the entire channel is removed
2919 then it must also delete the references of the channel entry
2920 from the client's channel list as the client's channel entry and
2921 the channel's client entry share same memory.
2923 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Implemented CONNECT and SHUTDOWN commands in the client.
2927 * Implemented CLOSE command to the client.
2929 * Added the function silc_idlist_find_server_by_name into the
2930 files silcd/idlist.[ch].
2932 Added the function silc_idlist_find_server_by_conn into the
2933 files silcd/idlist.[ch].
2935 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * DIE command was renamed to SHUTDOWN. Updated the both code
2940 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2941 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2943 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2946 * Added function silc_server_create_connection function to create
2947 connection to remote router. My server implementation actually
2948 does not allow router to connect to normal server (it expects
2949 that normal server always initiates the connection to the router)
2950 so the CONNECT command is only good for connecting to another
2953 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2955 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2956 or some other client was kicked from the channel.
2958 Implemented the handling of the notify type to both client
2961 Implemented silc_server_send_notify_kicked to send the KICKED
2962 notify. It is used to send it to the server's primary router.
2964 * Implemented the KICK command into server and client.
2966 * Added `query' argument to the silc_idlist_get_client function
2967 to indicate whether to query the client from server or not if
2970 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2971 to indicate that the client is not channel founder.
2975 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Removed the rng context from SilcPacketContext structure and
2978 changed that the packet routine uses the Global RNG API.
2980 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Added support for quit message that client can "leave" on the
2983 channel when it quits the SILC. It is ditributed inside the
2984 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2986 Added silc_server_free_client_data that will take the
2987 signoff message as argument.
2989 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2991 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Updated parts of the protocol specification to keep it up
2996 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2999 payloads in one packet.
3001 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3002 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3003 use now the new List flag.
3005 * Also deprecated the following packet types: REPLACE_ID,
3006 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3008 * Added list support for Notify packet in server.
3010 * Added silc_server_send_notify_channel_change to send the
3011 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3012 the silc_server_send_replace_id.
3014 * Added silc_server_send_notify_nick_change to send the
3015 NICK_CHANGE notify type. Deprecates the function
3016 silc_server_send_replace_id.
3018 * Added silc_server_send_notify_join to send the JOIN notify type.
3019 Deprecates the function silc_server_send_new_channel_user.
3021 * Added silc_server_send_notify_leave to send LEAVE notify type.
3022 Deprecates the function silc_server_send_remove_channel_user.
3024 * Added silc_server_send_notify_cmode and
3025 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3026 types. Deprecates the silc_server_send_set_mode function.
3028 * Added SERVER_SIGNOFF notify type to indicate that server has
3029 quit. This means that all clients on the channel from that
3030 server will drop. This can be also used when netsplit happens.
3032 Deprecated REMOVE_ID packet type since it is not needed anymore
3035 Added silc_server_send_notify_server_signoff to send the
3036 SERVER_SIGNOFF notify type. Deprecates the function
3037 silc_server_send_remove_id.
3039 Added also silc_server_send_notify_signoff to send the
3040 SIGNOFF notify type.
3042 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3043 SILC protocol from this day on. Changed the protocol
3044 specification as well.
3046 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3047 notify type. It is used between routers to notify about
3048 topic changes on a channel.
3050 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3053 * Partly updated the protocol specification to comply with the
3054 changes now made. It is still though a bit outdated.
3056 * The JOIN notify type now takes one extra argument <Channel ID>.
3057 The packet used to be destined to the channel but now the
3058 JOIN type may be sent as list thus it is impossible to
3059 destine it to any specific channel. By adding this argument
3060 it is again possible.
3062 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3064 * Added CREDITS file. The CHANGES and CREDITS file will appear
3065 in the distribution as well.
3067 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3070 types in the server's silcd/packet_receive.c.
3072 * Implemented CMODE and CUMODE to work in router environment.
3074 * Fixed minor encoding and decoding buglet from the
3075 lib/silccore/silcmode.c.
3077 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3080 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3082 * Changed all SilcConfigServer* and silc_config_server* to
3083 SilcServerConfig* and silc_server_config*, respectively.
3086 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Associated the ID (client or server ID) to the Authentication
3089 Payload to avoid any possibility of forging. Updated the
3090 protocol specification and the code accordingly.
3092 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * The RSA key length is now save to the RsaKey context in the
3095 key generation process in lib/silccrypt/rsa.c. The key length
3096 is now used to figure out the maximum size of the block allowed
3097 to be encrypted/signed.
3099 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3100 is equivalent to the silc_mp_mp2bin but does not allocate any
3103 * Changed silc_mp_mp2bin API to take length argument. If it is
3104 non-zero then the buffer is allocated that large. If zero, then
3105 the size is approximated using silc_mp_sizeinbase, which however
3108 * Created Global RNG API which is global RNG that application can
3109 initialize. After initializing, any routine anywhere in the
3110 code (including library) can use RNG without allocating a new
3111 RNG object. This was done to allow this sort of use of the
3112 RNG in code that has no chance to allocate RNG object. All
3113 applications currently allocate this and many routines in the
3114 library use this. Affected file lib/silccrypt/silcrng.[ch].
3116 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3117 it to use the Global RNG API.
3119 * Defined Authentication Payload into protocol specification that
3120 is used during SILC session to authenticate entities. It is
3121 used for example by client to authenticate itself to the server
3122 to obtain server operator privileges.
3124 Implemented this payload into the lib/silccore/silcauth.[ch].
3125 Implemented also routines for public key based authentication
3126 as the new protocol specification dictates.
3128 Moved definitions of different authentication methods from
3129 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3131 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3132 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3133 silc_pkcs_verify_with_hash functions into the file
3134 lib/silccrypt/silcpkcs.[ch].
3136 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * The client entry's userinfo pointer must be always valid.
3139 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3140 will fail since it requires the userinfo. Now, the userinfo
3141 is allocated as "" if actual userinfo does not exist. Actually,
3142 it must exist and it is totally Ok to drop client connections
3143 that does not announce the userinfo. However, we will make
3144 this workaround for now.
3146 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3147 to return the remote port by socket.
3149 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3152 SILC_SERVER_PENDING_EXEC and added an new macro
3153 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3154 data or when error occurs while processing the pending command.
3156 Added new argument `destructor' into silc_server_command_pending
3157 and to the SilcServerCommandPending object. This destructor is
3158 now called after calling the pending callback or if error occurs
3159 immediately. If error occurs the actual pending callback won't
3160 be called at all - only the destructor. The destructor may be
3161 NULL if destructor is not needed.
3163 All this applies for client library code as well. Similar
3164 changes were made there as well for the pending commands.
3166 In the client, the application must now allocate the
3167 SilcClientCommandContext with the silc_client_command_alloc
3170 * Added reference counter to the SilcServerCommandContext. Added
3171 function silc_server_command_alloc and silc_server_command_dup
3174 Same type of functions added to the client library for the same
3177 * Removed the cmd_ident from IDListData away since it is now
3178 global for all connections. It is the command identifier used
3179 in command sending and with pending commands. The affected file
3182 * Added reference counter to the SilcSocketConnection objecet to
3183 indicate the usage count of the object. The object won't be
3184 freed untill the reference counter hits zero. Currently only
3185 server uses this, and client ignores it. The client must be
3186 set to use this too later. The affected files are
3187 lib/silccore/silcsockconn.[ch]. Added also the function
3188 silc_socket_dup to increase the reference counter.
3190 This was mainly added because it is possible that the socket
3191 is removed underneath of pending command or other async
3192 operation. Now it won't be free'd and proper DISCONNECTING
3193 flags, etc. can be set to avoid sending data to connection that
3194 is not valid anymore.
3196 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3197 the connection. After that it sets SILC_SET_DISCONNECTED.
3198 It is, however, possible that the socket data is not still freed.
3199 The silc_server_packet_process now checks that data is not
3200 read or written to connection that is DISCONNECTED. The socket
3201 get's freed when the reference counter hits zero.
3203 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Changed the client operation API: channel_message operation's
3206 `sender' is now the client entry of the sender, not the nickname
3207 and the `channel' is the channel entry, not the channel name.
3209 In the private_message operation the `sender' is now also the
3210 client entry of the sender not the nickname.
3212 Affected file is lib/silcclient/ops.h and all applications
3213 using the client operations.
3215 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Moved the calling of ops->connect() from connect_to_server_final
3218 into receive_new_id functin since that is the point when the
3219 client is actually allowed to send traffic to network. The
3220 affected file is lib/silcclient/client.c.
3222 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3225 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3226 (if needs broadcasting) instead of broadcasting the packets one
3227 by one which would make a burst in the network traffic.
3229 * Added `broadcast' argument to the functions in silcd/server.[ch]
3230 silc_server_create_new_channel[_with_id] to indicate whether
3231 to send New Channel packet to primary router.
3233 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added new function into the silcd/server.[ch] files:
3236 silc_server_create_new_channel_with_id to create new channel with
3237 already existing Channel ID.
3239 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3240 lib/silccore/silcpacket.h. This packet is used t send list of
3241 Set Mode payloads inside one packet. Server uses this to set
3242 the modes for the channels and clients on those channels, that it
3243 announced to the router when it connected to it. The protocol
3244 specification has been updated accordingly.
3246 * The silc_server_new_channel did not handle the packet coming
3247 from normal server as it normally does not send that. However,
3248 when it announces its channels it does send it. Implemented
3249 the support for that.
3251 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3252 into the file lib/silccore/id.h.
3254 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Fixed memory leaks in the functions silc_idlist_del_client,
3257 silc_idlist_del_channel and silc_idlist_del_server in the file
3258 silcd/idlist.c. All of those leaked like a sieve.
3260 * Fixed some small memory leaks in the client's function
3261 silc_client_notify_by_server.
3263 * Added functions into silcd/server.c: silc_server_announce_clients,
3264 silc_server_announce_channels and silc_server_announce_server.
3265 These functions are used by normal and router server to announce
3266 to its primary router about clients, channels and servers (when
3267 router) that we own. This is done after we've connected to the
3270 These functions effectively implements the following packet types:
3271 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3272 and SILC_PACKET_NEW_ID_LIST.
3274 * Added new functions into the silcd/packet_receive.[ch]:
3275 silc_server_new_id_list, silc_server_new_channel_list and
3276 silc_server_new_channel_user_list to handle the incoming
3277 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3279 * Added support of changing Channel ID in the function
3280 silc_server_replace_id. If the server that announces a channel
3281 to the router already exists in the router (with same name but
3282 with different Channel ID), router is responsible to send
3283 Replace ID packet to the server and force the server to change
3284 the Channel ID to the one router has.
3286 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3287 client that the Channel ID has been changed by the router. The
3288 normal server sends this to the client. Client must start using
3289 the new Channel ID as the channel's ID.
3291 Implemented handling of this new type into lib/silcclient/client.c
3292 into the function silc_client_notify_by_server.
3294 * Added new function silc_idlist_replace_channel_id into the files
3295 silcd/idlist.[ch] to replace the Channel ID.
3297 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Call silc_server_command_identify_check always when processing
3300 the IDENTIFY command in silcd/command.c
3302 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3305 send keepalive packets. The packet can be sent by clients,
3306 servers and routers.
3308 Added function silc_socket_set_heartbeat into the file
3309 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3310 If not set, the heartbeat is not performed. The actual
3311 heartbeat is implemented in the low level socket connection
3312 library. However, application is responsible of actually
3315 Added silc_server_send_heartbeat to send the actual heartbeat
3316 packet into silcd/packet_send.[ch]. Server now performs
3317 keepalive with all connections.
3319 * Added silc_task_get_first function into lib/silcutil/silctask.c
3320 to return the timeout task with shortest timeout. There was a bug
3321 in task unregistration that caused problems. TODO has been
3322 updated to include that task system must be rewritten.
3324 * The client library will now resolve the client information when
3325 receiving JOIN notify from server for client that we know but
3326 have incomplete information.
3328 * Rewrote parts of silc_server_remove_from_channels and
3329 silc_server_remove_from_one_channel as they did not remove the
3330 channel in some circumstances even though they should've.
3332 * Encryption problem encountered in server:
3334 The LEAVE command used to send the Channel Key packet to the
3335 router immediately after generating it. However, the code
3336 had earlier sent Remove Channel user packet but not immediately,
3337 ie. it was put to queue. The order of packets in the router
3338 was that Channel Key packet was first and Remove Channel User
3339 packet was second, even though they were encrypted in the
3340 reverse order. For this reason, MAC check failed. Now, this
3341 is fixed by not sending the Channel Key packet immediately but
3342 putting it to queue. However, this is more fundamental problem:
3343 packets that are in queue should actually not be encrypted
3344 because packets that are sent immediately gets encrypted
3345 actually with wrong IV (and thus MAC check fails). So, packets
3346 that are in queue should be encrypted when they are sent to
3347 the wire and not when they put to the queue.
3349 However, the problem is that the current system has not been
3350 designed to work that way. Instead, the packet is encrypted
3351 as soon as possible and left to the queue. The queue is then
3352 just purged into wire. There won't be any fixes for this
3353 any time soon. So, the current semantic for packet sending
3356 o If you send packet to remote host and do not force the send
3357 (the packet will be in queue) then all subsequent packets to the
3358 same remote host must also be put to the queue. Only after the
3359 queue has been purged is it safe again to force the packet
3362 o If you send all packets immediately then it safe to send
3363 any of subsequent packets through the queue, however, after
3364 the first packet is put to queue then any subsequent packets
3365 must also be put to the queue.
3367 Follow these rules and everything works fine.
3369 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Added new function silc_server_remove_clients_by_server to
3372 remove all client entries from ID list when the server connection
3373 is lost. In this case it is also important to invalidate all
3374 client entires as they hold the invalid server entry. This
3375 fixes fatal bug when server has lost connection and will reconnect
3378 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Made some sanity checks to silc_server_daemonise like to check
3381 whether the requested user and group actually exists.
3383 * Added sanity check to SKE's silc_ske_responder_finish to check
3384 that the public and private key actually is valid.
3386 * Invalidate the client's nickname when receiving Replace ID
3387 packet and the Client ID is being replaced. This means that the
3388 server will query the nickname if someone needs it (client)
3391 * Sort the ID Cache in client library when the ID Cache data
3392 has changed (needs sorting).
3394 * Do not allow for SILC client to create several connections to
3395 several servers. The client does not support windows right now
3396 and generating multiple connections causes weird behaviour.
3398 Irssi-silc client does support windows and can handle several
3399 connections without problems, see: www.irssi.org and SILC plugin.
3401 * Fixed some places where client was added to the IDList. The
3402 rule of thumb is following (in order to get everything right):
3403 If the client is directly connected local client then the
3404 `connection' argument must be set and `router' argument must be
3405 NULL to silc_idlist_add_client function. If the client is not
3406 directly connected client then the `router' argument must
3407 bet set and the `connection' argument must be NULL to the
3408 silc_idlist_add_client function.
3410 * The funtion silc_server_packet_send_local_channel actually did
3411 not check whether the client was locally connected or not. It
3412 does that now. Fixed a bug related to LEAVE command.
3414 * Fixed Remove Channel User payload parsing bug in server's
3415 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3417 * The server's silc_server_save_channel_key now checks also the
3418 global ID list for the channel as it might not be in the local
3419 list. Fixed a bug related to LEAVE command.
3421 * Is this the end of the [<unknown>] buglet that has been lurking
3422 around for a long time? A little for loop fix in server's
3423 silc_server_command_whois_parse that is used by both IDENTIFY
3424 and WHOIS command. At least, this was a clear bug and a cause
3425 of one type of [<unknown>] buglet.
3427 * WHOIS and IDENTIFY commands call the function
3428 silc_server_command_[whois/identify]_check function even if
3429 we are not router server.
3431 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3433 * Added --with-gmp configuration option. If set the GMP
3434 is always compiled in the SILC source tree. If not set then
3435 it is checked whether the system has the GMP3 installed. If
3436 it has then the GMP won't be compiled (the system's headers
3437 and library is used), if it doesn't have it then the GMP is
3438 compiled in the SILC source tree.
3440 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Changed RSA private exponent generation to what PKCS #1
3443 suggests. We try to find the smallest possible d by doing
3444 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3445 not security fix but optimization.
3447 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Added new config entry [Identity] to fork the server and run
3450 it as specific user and group. A patch from Bostik.
3452 * Imported Dotconf configuration library into lib/dotconf.
3453 This will be used to create the SILC configuration files later.
3454 It will appear in the distsribution after this commit.
3456 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * A big code auditing weekend happening. Auditing code for
3459 obvious mistakes, bugs and errors. Also, removing any code
3462 Removed files for being obsolete:
3464 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3465 inline in the file lib/silcutil/silcbuffer.h)
3467 o lib/silcutil/silcbufutil.c (the header has inline versions)
3469 Changed code to fix possible error conditions:
3471 o The buffer formatting routines now check that the destination
3472 buffer really has enough space to add the data. This applies for
3473 both buffer formatting and unformatting
3474 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3475 unformatting was changed to accomodate following rules:
3476 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3477 sent to the function while XXX_*STRING will not allocate or copy
3478 the data into the buffer. Instead it sets the pointer from the
3479 buffer into the pointer sent as argument (XXX_*STRING used to
3480 require that the pointer must be allocated already). This change
3481 makes this whole thing a bit more consistent and more optimized
3482 (note that the data returned in the unformatting with XXX_*STRING
3483 must not be freed now). The routines return now -1 on error.
3485 o Tried to find all code that use buffer_format and buffer_unformat
3486 and added return value checking to prevent formatting and
3487 especially unformatting errors and possible subsequent fatal
3490 o Changed ske->x and ske->KEY to mallocated pointers in
3491 lib/silcske/silcske.h. Fixed possible data and memory leak.
3493 o Added return value checking to all *_parse* functions. Fixed
3494 many memory leaks as well.
3496 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3497 so that buffer overflows would not happen. All code now also
3498 checks the return value as it can fail.
3500 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Added reconnection support to server if the normal server looses
3503 its connection to the router (for example if router is rebooted).
3504 The server performs normal reconnection strategy implemented
3505 to the server. Affected file silcd/server.c.
3507 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3509 * Added new packet type SILC_PACKET_SET_MODE that is used to
3510 distribute the information about changed modes (for clients,
3511 channels and clients channel modes) to all routers in the
3512 network. Updated the protocol specification accordingly.
3514 Added functions into silcd/packet_send.c and
3515 silcd/packet_receive.c: silc_server_send_set_mode,
3516 silc_server_set_mode.
3518 Added new files silcmode.[ch] into lib/silccore that implements
3519 the encoding and decoding of Set Mode Payload. Added new type
3520 SilcSetModePayload. Moved the definitions of different modes
3521 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3523 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Oops, a little mistake in server's connection authentication
3526 protocol. The protocol is not ended with FAILURE but with
3527 SUCCESS if the authentication is Ok. :) Affected file is
3530 * Implemented NICK_CHANGE notify handling in server in the file
3531 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3532 the local clients on the channel. After the changing nickname
3533 in router environment snhould work and the [<unknown>] nickname
3534 should appear no more.
3536 The silc_server_replace_id function that receives the Replace ID
3537 payload now sends the NICK_CHANGE notify type also in the file
3538 silcd/packet_receive.c
3540 * Changed WHOIS and IDENTIFY command to support the maximum amount
3541 of arguments defined in protocol specs (3328 arguments). This
3542 fixed a bug that caused problems when there were more than three
3545 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added extra parameter, command identifier, to the
3548 silc_client_send_command so that explicit command identifier
3551 Changed that ID list routines uses specific command identifier
3552 when sending WHOIS/IDENTIFY requests to the server so that they
3553 can be identified when the reply comes back.
3555 Affected files lib/silcclient/command.[ch],
3556 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3558 * Added `sender' argument to silc_server_packet_send_to_channel
3559 to indicaet the sender who originally sent the packet to us
3560 that we are now re-sending. Ignored if NULL. Affected file
3561 silcd/packet_send.[ch].
3563 * Added some server statistics support in silcd/server_internal.h
3564 SilcServerStatistics structure and around the server code. Also
3565 send some nice statistics information when client is connecting
3568 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Fixed channel ID decoding in server's JOIN command reply in
3571 silcd/command_reply.c
3573 * Fixed braodcasting of replace ID payload to not to send it if
3574 we are standalone server in silcd/packet_receive.c.
3576 * Fixed all channel message sending routines to not to send
3577 packets to clients that has router set, since they are routed
3578 separately in the same function earlier. Affects file
3579 silcd/packet_send.c and all channel packet sending functions.
3581 * In USERS reply, res_argv[i] are not allocated, the table
3582 is allocated. Thus changed that free the table, not its
3585 * In server's whois_check and identify_check if the client is
3586 locally connected do not send any WHOIS commands - they are not
3589 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Fixed some minor bugs in client when sending WHOIS command. The
3592 arguments was in wrong order.
3594 * Removed statis function add_to_channel from server in
3595 silcd/command.c that was previously used with the joining but
3598 * Tested USERS command in router environment successfully with two
3599 routers, two servers and two clients.
3601 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Reorganized the USERS command and command reply in client library
3604 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3605 When the command is given by user we register a pending command
3606 callback that will reprocess the command after the reply has been
3607 received from the server. When reprocessing the packet we then
3608 display the information. Thus, the USERS information is displayed
3609 now in the command callback instead of in the command reply
3610 callback. The processing of the command is same as previously
3611 when server has sent the command reply in the JOINing process.
3613 * Added to USERS command in silcd/command_reply.c to join the client,
3614 we didn't use to know about, to the channel after we've created
3615 a client entry for it. Also, for clienet we did know already still
3616 check whether it is on the channel or not and add it if not.
3618 * Removed silc_server_command_join_notify as the function and its
3621 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Changed the client's pending command handling to the same as the
3624 server's pending command handling. It is also now possible to
3625 execute command reply functions from other command reply
3626 function as the function callbacks for commands and command
3627 replies are one and same. The pending commands are not static
3628 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3629 in client connection context. Thus, pending commands are server
3630 connection specific as it is convenient.
3632 Changed the function silc_client_command_pending and
3633 silc_client_command_pending_del and added new function
3634 silc_client_command_pending_check. Removed the
3635 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3638 * Added cmd_ident, current command identifier, to the client
3639 connection context in lib/silcclient/client.h to keep track on
3640 command identifiers used in command sending. Client's command reply
3641 function handling now supports the mandatory command identifiers.
3643 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3644 funtions in client to fully support pending command callbacks.
3646 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3647 as one of the arguments to the application in the command reply
3650 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3651 before first releasing SILC but came back. Now it is removed again
3652 and should come back nomore. The FORWARDED flag was used only
3653 by the JOINing procedure by forwarding the command packet to router.
3654 Now, the JOINing procedure has been changed to more generic (due
3655 to various router environment issues) and FORWARDED is not needed
3656 anymore for anything. The protocol specification is yet to be
3659 Now, removed silc_server_packet_forward from server and the flag
3660 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3662 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Renamed NAMES command to USERS command. The NAMES was named that
3665 due to historical reasons. Now it is renamed. Also, rewrote
3666 parts of the USERS command. The nickname list is not sent anymore
3667 by the server. Only Client ID and mode lists are sent in the USERS
3668 command. Changed this also to the protocol specification.
3670 The client now resolves the names and stuff after it receives
3671 the USERS list from the server when joining to the channel.
3673 * WHOIS and IDENTIFY commands has been changed to support multiple
3674 Client ID's per command. One can now search for multiple users
3675 in the network by sending only one WHOIS or IDENTIFY command.
3676 Changed the code and the protocol specifications.
3678 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3679 uses silc_server_command_whois_parse to parse the request. */
3681 * If normal server, do not parse the WHOIS and IDENTIFY requests
3682 before sending it to the router. Saves some time.
3684 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Fixed JOIN command on client library. Wrong number of arguments
3687 used to crash the client.
3689 * Added silc_server_channel_has_global function to check whether
3690 channel has global users or not.
3692 * Added silc_server_channel_has_local function to check whether channel
3693 has locally connected clients on the channel.
3695 * The silc_server_remove_from_one_channel now checks whether the
3696 channel has global users or not after given client was removed from
3697 the channel. It also checks whether the channel has local clients
3698 on the channel anymore. If it does not have then the channel entry
3699 is removed as it is not needed anymore.
3701 * The silc_server_notify now checks on JOIN notify whether the joining
3702 client is one of locally connected or global. If it is global then
3703 the channel has now global users on the channel and that is marked
3704 to the channel entry. Also, it now saves the global client to
3705 global list who is joining and JOINs it to the channel. This is
3706 for normal server, that is.
3708 Changed silc_server_send_notify_on_channel,
3709 silc_server_packet_relay_to_channel and
3710 silc_server_packet_send_to_channel check if we are normal server
3711 and client has router set (ie. global client) do not send the
3712 message to that client, as it is already routed to our router.
3714 * Implemented LEAVE notify type handling in silc_server_notify
3717 * Tested LEAVE command in router environment successfully. Tested
3718 with two routers, two servers and two clients.
3722 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3724 * Implemented SIGNOFF notify type handling in silc_server_notify
3727 * silc_server_remove_id now removes the client entry from all channels
3728 it has joined and thusly sends SIGNOFF notify type.
3730 * Rewrote the NAMES list generation in server by removing two excess
3731 loops. The lists are created now inside one loop.
3733 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * silc_server_remove_channel_user checks now also global list
3736 for channel and client.
3738 * silc_server_new_channel_user checks now both local and global
3739 list for channel and client. Fixed a bug in client id decoding.
3740 Used to decode wrong buffer.
3742 * silc_server_channel_message checks now both local and global
3743 list for channel entry.
3745 * Tested channel joining (hence JOIN) in router environment
3746 successfully. Tested with two routers, two servers and two
3749 * Tested channel message sending in router environment successfully.
3751 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Added silc_server_save_channel_key into server.[ch] to save the
3754 received channel key in Channel Key payload processing. It is
3755 also used in JOIN command reply handling.
3757 Equivalent function silc_client_save_channel_key added into
3758 client.[ch] into client library.
3760 * Changed JOIN command reply to send information whether the channel
3761 was created or not (is existing already) and the channel key
3762 payload. Changed protocol specs accordingly.
3764 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3765 the request was sent by ID and not by nickname. Crashed on
3768 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3771 now correctly save the received data.
3773 * silc_server_free_sock_user_data now notifies routers in the
3774 network about entities leaving the network.
3776 At the same time implemented functions silc_server_remove_id
3777 and silc_server_send_remove_id to receive and send REMOVE_ID
3778 packets. The packet is used to notify routers in the network
3779 about leaving entities. The ID removed will become invalid in
3782 * Added function silc_idlist_del_server into server. Removes and
3783 free's server entry from ID list.
3785 * silc_server_private_message function now checks, if we are router,
3786 that the destination ID really is valid ID, naturally.
3788 * In router when NEW_ID packet is received (for new client) the
3789 hash of the Client ID is saved in the ID Cache but the
3790 client->nickname is set to NULL, instead of putting the hash
3793 IDENTIFY command now also checks that client->nickname must be
3794 valid. If it is not if will request the data from the server who
3795 owns the client. Added new function
3796 silc_server_command_identify_check.
3798 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3799 to set the command to already allocated Command Payload.
3801 * Tested private message sending in router environment with two
3802 routers, two servers and two clients. Fixed minor bugs and now
3805 * Fixed segfault from client's NAMES command. Used to crash if
3808 * Forwarded packets must not be routed even if it is not destined
3809 to the receiver. Changed server code comply with this.
3811 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Added `require_reverse_mapping' boolean value to ServerParams
3814 structure. If TRUE (not default) the server will require that
3815 the connecting host has fully qualified domain name.
3817 If the reverse mapping is not required and hostname could not be
3818 found the IP address is used as hostname.
3820 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Implemented version string checking to both client and server.
3823 The check is incomplete currently due to the abnormal version
3824 strings used in development version of SILC.
3826 * Changed all command functions in server to use the new
3829 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Changed char *data to unsigned char *data in ID Cache system to
3832 support binary data as ID Cache data. Changed code to support
3833 binary data in lib/silccore/idcache.c.
3835 * Renamed silc_server_packet_relay_command_reply to
3836 silc_server_command_reply as it is normal packet receiving
3837 function. Rewrote the function to accept command replys for
3838 servers and not only for clients.
3840 * Mark remote router always as registered server if we are connecting
3841 to it. Otherwise, commands sent by the router to us are ignored.
3843 * All ID List find routines now returns the ID Cache Entry pointer
3844 as well if requested.
3846 * WHOIS command works now in router environment, tested with two
3847 routers, two servers and two clients.
3849 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3850 in router environment (as it is almost equivalent to WHOIS) but
3851 hasn't been tested thoroughly. Added new functions:
3853 silc_server_command_identify_parse
3854 silc_server_command_identify_send_reply
3855 silc_server_command_identify_from_client
3856 silc_server_command_identify_from_server
3858 * Disabled route cache adding because adding two different ID's with
3859 same IP replaces the old cache entry thus giving wrong route.
3860 The entry->router->connection is always the fastest route anyway
3861 so route cache may not be needed. Of course, new routes maybe
3862 established after receiving the ID when the entry->router->connection
3863 might not be anymore the most optimal.
3865 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Add route cache for received ID for fast routing.
3869 * Added silc_server_packet_route to route received packet on router
3870 that is not destined to us.
3872 * Renamed silc_server_get_route to silc_server_route_get.
3874 * Added id_string and id_string_len fields into SilcServer to
3875 include encoded ServerID for fast comparing without excess
3876 encoding of the ID's.
3878 * Cleaned up WHOIS command on server side. Added following static
3881 silc_server_command_whois_parse
3882 silc_server_command_whois_check
3883 silc_server_command_whois_send_reply
3884 silc_server_command_whois_from_client
3885 silc_server_command_whois_from_server
3887 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3888 arguments in command replies. All command functions should be
3889 updated to use this macro.
3891 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Minor typo fixes on command reply handling on server.
3895 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Added silc_server_command_add_to_channel internal routine to add
3898 the client to the channel after router has created the channel and
3899 sent command reply to the server.
3901 * Added generic silc_server_send_command to send any command from
3904 * Use static buffer with ID rendering instead of duplicating data.
3906 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Fixed a channel user mode bug when joining to a channel server gave
3909 everybody channel founder rights, oops.
3911 * We mark ourselves as the router of the incoming server connection
3912 if we are router ourselves. This way we can check in some packet
3913 sending functions whether it is locally connected server. For
3914 incoming router connections we put NULL.
3916 * For router sending packets locally means now always sending the
3917 packet cell wide; to local clients and local servers. For normal
3918 server sending packet locally means sending it to only local
3921 * Fixed the JOIN command to really work in router environment. If the
3922 channel is created it is always created by the router. Router is
3923 also responsible of making the initial joining to the channel,
3924 sending JOIN notify to the sending server and distributing
3925 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3926 does not exist server doesn't do anything else but forward the
3927 command to the router which performs everything.
3929 * Added silc_server_send_channel_key function to send the Channel Key
3932 * Added silc_server_create_channel_key to create new channel key. The
3933 channel key is now re-generated everytime someone joins or leaves
3934 a channel, as protocol dictates. Note: channel->key_len is the
3937 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3940 packet_receive.[ch] to separate packet sending and receiving
3941 routines. The server.[ch] now includes everything else including
3942 actual packet processing (writing and reading data) and other
3945 Renamed silc_server_private_message_send_internal to
3946 silc_server_send_private_message. The routine is still though
3947 used only to relay private messages as server does not send
3948 private messages itself.
3950 Renamed silc_server_new_channel to silc_server_create_new_channel
3951 and added new function sicl_server_new_channel that handles the
3952 incoming New Channel packet. Added also new sending function
3953 silc_server_send_new_channel to send New Channel Payload.
3955 * Added new function silc_server_notify to process incoming notify
3956 packet to the server/router. Server may then relay the notify
3957 to clients if needed.
3959 * Added new function silc_server_new_channel_user to process incoming
3960 New Channel User packet. Router will redistribute the packet and
3961 send JOIN notify to its local clients and locally connected servers
3962 if needed. Normal server will send JOIN notify to its local client
3963 on same channel when received this packet. Added also corresponding
3964 sending function silc_server_send_new_channel_user to sent the
3967 * Added boolean route argument to send_notif_to_channel and
3968 packet_send_to_channel functions to attempt to route the packet
3969 if it is TRUE and send only locally if it is FALSE.
3971 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * silc_server_replace_id now broadcasts the received replace ID
3974 packet if it is not broadcast packet already. The router must
3975 broadcast to inform other routers about changed ID.
3977 * Added backpointer to server's router into SilcServer context in
3978 silcd/server_internal.h.
3980 * Fixed silc_server_packet_broadcast to send correct broadcast
3983 * The channel key is now distributed to the local client as soon
3984 as it is received from the router (in router environment) so that
3985 no other packet may be sent for the channel until client has
3988 * silc_server_remove_channel_user now broadcasts the received
3989 Remove Channel User packet if it is not broadcast packet already.
3990 The router must broadcast to inform other routers about removed
3993 * Added users field into SilcPacketContext that is a reference count
3994 of the context. One can increase the reference count by calling
3995 silc_packet_context_dup which is now changed to just increase the
3996 reference count instead of duplicating the data. The reference
3997 count is decresed by calling silc_packet_context_free that will
3998 free the data after the reference count hits zero.
4000 For now on the packet context and everything allocated into it
4001 (including the raw packet from network) must be freed by calling
4002 the new silc_packet_context_free function. Added also new function
4003 silc_packet_context_alloc that must be used now to allocate the
4004 context. This also means that if a routine is asynchronous from
4005 silc_[client/server]_packet_parse_type the packet context must
4006 be duplicated by calling silc_packet_context_dup. Otherwise it
4007 gets free'd after silc_[client/server]_packet_parse_type returns.
4008 Also, one must remember that if packet is duplicated then its
4009 reference count must be decresed by calling the free function as
4010 many times as it was duplicated.
4012 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4013 from both client and server.
4015 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Made joining to a channel working in router environment.
4019 * Cleaned up JOIN command on server side and create function
4020 silc_server_command_join_channel internal routine to make the
4023 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Changed silc_command_pending list to SilcDList. Also, added
4026 `ident' field to SilcServerCommandPending structure to identify
4027 the reply and to call correct callback.
4029 Added silc_server_command_pending_check function to replace the
4030 corresnponding macro. The silc_command_pending list is not
4033 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4034 to set identifier to previously allocated Command Payload. It
4035 is used to set identifier for command when resending Command
4038 * Added silc_command_payload_encode_payload to encode Command
4039 Payload buffer from SilcCommandPayload structure.
4041 * Added silc_argument_payload_encode_payload to encode Argument
4042 payload buffer from SilcArgumentPayload structure.
4044 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Changed WHOIS command to support router connection on server side.
4047 The whois request is always sent to router unless the server is
4048 standalone server. After server has received the reply from the
4049 router will it send the reply to the client.
4051 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4052 broadcast received broadcast packet. The function is used only
4053 by router. The broadcast packet is always sent to the router's
4056 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4057 render given ID to printable string, for log files for example.
4059 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Made basic router to router connections working. At least they
4062 can now connect to each other but nothing really works the way
4063 they are supposed - yet.
4065 * Added new initiator token to RouterConnection configuration
4066 file in silcd/serverconfig.[ch]. It is used to tell whether we
4067 are the initiator to the remote router or whether we'll expect
4068 the other end to connect.
4070 * Moved registering of listener task to silc_server_init, hence
4071 the server starts listenning as soon as it is run, even if it
4072 does not have connections to other routers. Let's see how well
4075 * Changed default connection retry timeouts for more suitable in
4078 * Removed cipher and such arguments from silc_idlist_add_client
4079 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4080 Added new function silc_idlist_add_data to add the keys and stuff
4083 * Added SilcIDListData structure and added it to SilcClientEntry
4084 and SilcServerEntry as their first field in the structure. This
4085 way we can explicitly cast the ID entries to the SilcIDListData
4086 structure and get common data for the entries. In past, we had
4087 to first check what type of connection it is and then cast it to
4088 correct ID entry type. Now, we can directly cast the opaque
4089 pointer to the SilcIDListData (no matter what ID entry it actually
4090 is) and get the data needed.
4092 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4095 in some circumstances even if threre were timeout tasks, though not
4096 IO tasks, but tasks anyway. Now fixed.
4098 * Defined SilcServerConnection structure to hold connection specific
4099 stuff about directly connected servers and routers. The definition
4100 is currently in silcd/server_internal.h. I thought about having
4101 a bit more important role fro this struct but for now it is used
4102 only when connecting to other server (or router actually).
4104 * Added connecting retry support in server when connecting to
4105 router(s). The retry feature implement exponential backoff
4106 algorithm. Also, added SilcServerParams structure to hold default
4107 parameters for server. For now, it include these retry settings
4108 and are hard coded. After server is moded to be as Silc Server
4109 Library this structure will be more important.
4111 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Changed client librarys channel->clients table to SilcList and
4114 changed code accordingly.
4116 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Changed client's channel table to SilcList and changed code
4119 accordingly. Also changed SilcChannelClientEntry to include back-
4120 pointer to the channel so that client entry can use that structure
4121 as list as well and we have fast cross-reference to the channel.
4122 This change dramatically decreased the complexity of channel
4123 handling with client entry and vice versa (removed one extra
4124 loop when searching for channel entry from many functions).
4126 * Changed server->sim from table to SilcDList and changed code
4129 * NAMES command can now be used from user interface. It will show
4130 the user list on the channel, neatly.
4132 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4133 Code now saves realname of the user if it becomes available.
4135 * Renamed configure.in to configure.in.pre and made ./prepare
4136 script to automatically add correct version string to
4137 configure.in which it creates from configure.in.pre.
4139 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * NAMES command reply now shows users mode with the nickname when
4144 * Moved silc_client_ch[u]mode[_char] functions from
4145 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4146 place sucks, they are utility functions and should be in some
4149 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4151 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4154 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Added TRQ (efficient deque and list library) into lib/trq. This is
4159 a very good list library that is currently used in the SILC. Defined
4160 SilcList API over the library because I didn't like the API very
4161 much. See lib/trq/silclist.h for the API and examples of how to
4162 use the API. Fixed various places in the code to use the new
4163 SilcList API. The SilcList is meant for lists that has a structure
4164 already defined as a list. It is not suitable to add just some
4165 context to the list (in TRQ, the context is the list actually).
4167 So, I defined SilcDList that can be used for the purpose where
4168 predefined list structure does not exit. This can be used as
4169 such list. Now some context just can be added to the SilcDList.
4170 Currently this list is not used in the SILC just yet, though there
4171 are a lot places where this can replace dynamically allocated
4172 tables and I will fix these places, later, to use SilcDList.
4173 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4174 and use TRQ internally).
4176 Also fixed some annoying warning messages that the original TRQ
4177 code generated. Also minor changes to TRQ's Makefile.in.
4179 * Added support for querying by Client ID to both WHOIS and
4180 IDENTIFY commands into server, as required by the protocol.
4182 * Removed method function pointers from SilcBuffer structure. They
4183 weren't used to anything and just increased the context size for
4184 no good reason. This change also made silc_buffer_alloc and
4185 silc_buffer_free functions inline functions.
4187 * Disabled command flooding detection support until it's fixed so
4188 that it accepts commands in but does not execute them more than once
4191 * Added silc_net_localhost(), to return local hostname, into
4192 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4193 that must be initialized before calling silc_client_init.
4195 * Added new function: silc_server_send_notify_on_channels to send
4196 notify messages to all channels client has joined. It is assured
4197 that the message is sent only once per client.
4199 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4200 lib/silcutil/silcutil.[ch] as silc_format function. The new
4201 function is generic and is used by server as well, not only by
4202 the logging routines.
4204 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4205 the provided version string was not acceptable. Added new function:
4206 silc_ske_check_version into lib/silcske/silcske.h. The function
4207 must be implemented by the application (client or server) and it
4208 does not reside in the SKE library. The function checks the version
4209 string remote end sent.
4211 * Added back pointers (to opaque context and to SilcSocketConnection)
4212 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4214 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4215 duplicate packet context structure.
4217 * Changed `notify' client operation to send same arguments as client
4218 receives from server except for ID's. ID's are mapped to correct
4219 ID entry and that is returned. Also, if channel entry is not sent
4220 by server but the notify is for channel the channel entry is sent
4221 to application (otherwise application doesn't know that it is for
4222 channel (library gets it from packet's Destination ID)).
4224 * Added silc_client_remove_from_channels into client library to
4225 remove a client from all channels it has joined to. Used when
4226 received SIGNOFF notify from server. Added also new function
4227 silc_client_replace_from_channels to replace old ID entry with
4228 new ID entry on all channels. Used when received NICK_CHANGE
4231 * Fixed ID Cache list handling in silc_idlist_get_client in
4232 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4233 to get (or query) client by ID.
4235 * Updated TODO list.
4237 * Added connection authentication status message defined by the
4238 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4239 support for these into the code in client and server side.
4241 * Added generic function silc_client_send_command to send any command
4242 with variable argument list. Application should use this function
4243 to send commands if the command functions provided by the library
4244 does not suite for the application's user interface needs.
4246 * Added new `failure' client operation. Application is notified about
4247 received failure packet if client is executing a protocol. In this
4248 case the protocol's execution has failed.
4250 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4251 is required by the protocol.
4253 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4254 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4257 * Added status flag to SilcSKE object to indicate realtime status
4258 of the SKE protocol.
4260 * Application receives now exactly same command reply arguments as
4261 the library receives from server. However, if ID is received the
4262 corresponding ID entry is returned to the application (eg. Client
4263 ID is mapped to correct SilcClientEntry entry and that is returned).
4264 Changed command_reply client operation due to this change.
4266 * Changed all ID's in commands and in command replys as ID Payloads.
4267 Change affected both client and server side codes.
4269 All ID's sent in SILC network (with execption of ID's in SILC
4270 Packet header) are sent in ID Payload to support variable length
4273 * Server now notifies nick changes and notifies all clients on
4274 the channels about the new nickname (about the new Client ID,
4277 * Implemented CMODE command to change channel modes. Supports all
4278 channel modes defined by the protocol specs except ban and invite
4279 lists. (Also, private channel key mode is supported but support for
4280 setting private channel key in client is missing, thus, this mode
4281 has no effect on client side (except that server requires that the
4282 client uses private channel key and normal channel traffic does not
4285 Also, invite mode works per se, but INVITE command does not work
4286 yet correctly, so you can set channel as invite only channel but
4287 inviting clients to the channel does not work (it is yet to be
4288 thought what's the best way to do it).
4290 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4291 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4292 Implemented CUMODE command to change user's mode on the channel.
4293 Supports all modes defined by the protocol specs.
4295 * Added NAMES command reply to return users modes on the channel.
4297 * Removed unnecessary and slow ciphers from lib/silccrypt.
4299 * Set SO_KEEPALIVE option to connection sockets by default.
4301 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4303 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4304 redefined the Notify Payload into protocol specs.
4306 * Added silc_id_payload_parse_id to get ID directly from raw
4309 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4312 accept searching by Client ID as well.
4314 * Added support for LEAVE and SIGNOFF notify types in client library.
4316 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4317 to parse ID Payload from raw data.
4319 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Added flags parameter into silc_ske_assemble_security_properties
4322 function in lib/silcske/silcske.[ch].
4324 * Changed notify client operation to fit better for notify messages
4325 sent by server. The notify payload received from server is now
4326 passed to the application (after parsing it to SilcNotifyPayload).
4327 It is application's responsibility to retrieve the arguments
4328 from the payload and show the message the way it wants. The message
4329 sent by server is implementation specific.
4331 * Changed public keys to comply with the protocol specification.
4332 Old public keys are not supported anymore and are not compatible.
4334 * Removed nickname from Channel Payload as the latest draft removed
4335 it. The client must resolve the nickname from the NAMES command
4336 reply received when it joined the channel.
4338 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4340 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Fixed some errors in protocol specification drafts.
4344 * Created lib/silccore/silcnotify.c to implement Notify Payload
4345 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4346 generic payloads described by protocol specifications. The file
4347 includes implementations for ID Payload and Argument Payload.
4349 * Changed Command Payload implementation to use the new Argument
4350 Payload. Changed command_xxxx_payload to command_payload_xxxx
4351 to comply with SILC coding conventions.
4353 * Added suppport for Argument Payload handling in Notify Payload
4354 implementation as protocol requires it. Added the new support
4355 into server and client lib as well.
4357 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Added support for multiple nicknames on same channel. [n] is
4360 added locally to the nickname if there are more than one same
4361 nicknames on the channel.
4363 * Server now sends all nicknames that matched WHOIS request.
4364 Client also shows the list received from server.
4366 * Added TOPIC command to client side. User can now set and show
4367 current topic on channel.
4369 * Added MOTD command to client and server. Also, server sends the
4370 motd when client connects to the server.
4372 * Changed version strings to comply ISO 8601.
4374 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Fixed protocol error handling in client library. It should now
4377 cope even if the SKE fails for some reason.
4379 * Made new protocol specification drafts for submitting to IETF.
4381 * Implemented TOPIC command to server in silcd/command.c.
4383 * Added two new notify types into lib/silccore/silcnotify.h:
4384 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4385 notify nickname change and topic setting/change on a channel.
4387 * API change of command_reply operation in client library. The
4388 application gets now the status type received from server as well.
4390 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4394 * Cras fixed and optimized the packet handling even further and
4395 it should work now. Minor change to the prototype of function
4396 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4398 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Added new function into lib/silcutil/silcschedule.[ch]:
4401 silc_schedule_with_fd to select() a specified fd. The function
4402 returns after timeout expires or data arrives or goes. The
4403 function is used by packet routines to wait that all data is
4404 received from network.
4406 * Fixed data reading from network in lib/silccore/silcpacket.c.
4407 The code now assures that all data is read from the fd and then
4408 continues packet processing. This was a bug fix since the code
4409 used to drop some data in some circumstances.
4411 * Added new function into lib/silcclient/client.[ch]:
4412 silc_client_start_key_exchange to start key exchange after
4413 connection has been established to server. The code internally
4414 now uses this funtion but its main purpose was to provide it
4415 for applications that perform their own connecting. After
4416 application has created a connection it merely calls this
4417 function to start the key exchange between client and server.
4418 The library takes care of everything else after that.
4420 Updated also lib/silcclient/README to explain the usage of
4423 * Do not send to application information that connection has
4424 been established. Application gets notified it by connect
4427 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Applied cras's patch to add silc_schedule_one function. The
4430 function runs scheduler once and returns.
4432 * Fixed the scheduler after cras messed it up. The timeout
4433 handling works now as it's supposed to work.
4435 * Added into lib/silccore/ silcnotify.h to include notify
4436 message types support. Changed silc_server_send_notify*
4437 functions, in server.[ch], to support those new notify types.
4438 Added the support for the notify types into client library,
4439 as well. Added new notify client operation into ops.h in
4442 * Changed silc_server_packet_send_to_channel to send normal
4443 packets instead of just channel message packets. The function
4444 is now used to send the notify packets to channels. It is not
4445 used to send channel message packets anymore, as server never
4448 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4449 va_arg()s as it seems to require it nowadays. I guess, if SILC
4450 is compiled with older va_arg() the new code should work anyway.
4452 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Splitted core library. Core library (lib/silccore) includes
4455 now only SILC protocol specific core (and common) components.
4456 Created new utility library (lib/silcutil) that includes more
4457 generic purpose stuff. The stuff for util library was taken
4458 from the old core library. This was minor and easy split.
4460 * Created SILC Client Library (lib/silcclient) that includes
4461 implementation of the SILC client without user interface. This
4462 was major move from silc/ directory. The code has been changed
4463 so that it is transparent towards the user interface. The
4464 silc/ directory includes now the same user interface as before
4465 and it uses the new client library. Read lib/silcclient/README.
4466 Basicly, the client library performs everything else related
4467 to SILC except user interface handling. Also, configuration
4468 files are considered to be part of user interface and library
4469 does not handle them.
4471 This change also changed a lot of structures, function naming etc.
4472 Most important change was that SilcClientWindow object was
4473 renamed to SilcClientConnection in the client library. Created
4474 also new file lib/silcclient/ops.h. Also added new files
4475 silc/local_command.[ch] and silc/client_ops.[ch].
4477 All these changes were made to make it easier for user interface
4478 designers to create what ever user interface for the SILC client
4481 It is also expected that the server will be moved to lib
4482 directory as well and SILC Server Library will be created;
4483 sometimes in the future.
4485 * Removed Local commands from lib/silccore/silccommand.h as
4486 they are application specific and new client library does not
4487 handle any of those anymore.
4489 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4490 old client implementation in silc/.
4492 * Added support for callback functions in SILC_LOG_* macros.
4493 Application can now set its own callbacks that will be called
4494 instead of using the default functions that will always print
4495 the debug messages to stderr (or stdout). Also, debugging can
4496 now be disabled by setting silc_debug to FALSE and re-enabled by
4497 setting it to TRUE. Note, that logging will still work even
4498 if debugging is disabled.
4500 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4501 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4502 silc_log_reset_debug_callbacks.
4504 * To enable debugging in silc client one must give now -d
4505 option on command line.
4507 * Changed silc_schedule_init to automatically allocate task queues
4508 if they are not allocated before calling it.
4510 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Added GMP 3.1 into math library.
4514 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4517 a channel in SILC network. The packet is used by servers and
4518 routers to notify other routers that user has left a channel.
4519 This little feature was missing until now. Added the feature
4520 to protocol specification as well.
4522 Added functions: silc_server_send_remove_channel_user and
4523 silc_server_remove_channel_user into server.[ch].
4525 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4526 lib/silccore/silcpacket.h. However, they are not implemented
4529 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Fixed joining to a channel and sending channel messages
4532 between server and router. The channel message sending should
4533 now work inside a cell.
4535 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Fixed the private message sending between server and router.
4538 The private message sending should now work inside a cell.
4540 * Added silc_server_replace_id into server.[ch] to replace
4541 existing ID in the SILC network.
4543 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4544 and silc_idlist_replace_server_id into idlist.[ch] in server.
4546 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Fixed the server to server connections. Server can again now
4549 connect to router. Router to router connections probably does
4552 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added dynamic protocol registering support. Now protocols can
4555 registered and unregistered on the fly. Patch by cras.
4557 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Added lib/contrib directory to hold routines that some platforms
4560 don't have but are needed by SILC.
4562 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4563 into lin/contrib to provide getopt() and getopt_long() for
4564 those who don't have it.
4566 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added AWAY command to client. When away message is set and
4569 client receives a private message packet the client automatically
4570 replies to the sender with the away message.
4572 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4573 bug seemed to be the cause of recent problems when compiling
4576 * Added version detection support to SKE protocol specification
4577 and added the new changes to the SKE implementation as well.
4578 There were other minor changes in the SKE protocol as well.
4580 Many changes in lib/silcske/silcske.[ch] and in
4581 lib/silcske/payload.[ch].
4583 * Added ^U functionality, clear input line. Patch from cras.
4585 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Mainly small bugfixes on core library. Fixed some debugging
4588 logging and buffer overflow in silclog.c.
4590 * Updated config.sub and config.guess on the distribution tree.
4592 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added command lagging support in server. Client may execute
4595 commands now only once in two seconds.
4597 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Optimized packet reception. MAC computation and checking is now
4600 also more optimized. A lot previously duplicated code is now
4601 used as generic by both client and server.
4603 * Fixed key pair generation in clientutil.c
4605 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Added into lib/silccore/silcbufutil.[ch] new function;
4608 silc_buffer_realloc.
4610 * Moved generic packet sending/encryption functions to
4611 lib/silccore/silcpacket.[ch] from client and server. Some
4612 rewriting of the functions.
4614 * Moved all generic packet reception/decryption functions to
4615 lib/silccore/silcpacket.[ch] from client and server. The
4616 packet processing is now much cleaner in both client and server.
4617 These were major changes in both client and server.
4619 * Created many common functions in server to do packet sending.
4620 Previously code were duplicated a lot, this has been removed
4623 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Rewrote major parts of the ID cache system. Don't know
4626 whether it is better now or not but at least the API is more
4629 * Major rewrite on ID cache stuff on client because of the ID
4630 cache API changes. Added idlist.c to client.
4632 * Also major rewrite on ID cache stuff on server as well.
4633 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4634 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4635 in hand, instead they are all put into the ID cache system now.
4636 All server_idlist_* routines uses ID cache now instead of
4637 traversing its own lists (those lists does not exist anymore).
4638 SilcIDList though still exists. Also, SilcXXXEntry's are
4641 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Finally made the SKE implementation compliant to the protocol
4644 specification. All mp integers are now binary encoded as
4645 opposed being HEX encoded.
4647 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4650 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4651 functions: silc_[encode/decode]_pem. Also added function
4652 silc_encode_pem_file to PEM encode with newlines ('\n') for
4655 * SILC public keys are now encoded either PEM or binary. Same
4656 option is for private keys as well. By default private keys
4657 are binary encoded and public keys PEM encoded. Silly HEX
4658 encoding were removed.
4660 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4661 function to create fingerprints.
4663 * Fixed a bug in SHA1; does not change the original data anymore.
4665 * Partly implemented INFO command on client and server side.
4666 Fixed CLEAR command. Changes to SERVER command; show current
4667 server(s) when giving command without arguments. Added
4668 VERSION command to client.
4670 * Added check to server that unregistered connections cannot
4671 execute commands (unless it is specificly allowed).
4673 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Fixed screen refresh.
4677 * Fixed channel joining bug from client. On some circumstances
4678 client tried to join to a channel it had already joined.
4680 * Added public key verification process into client's protocol.c.
4681 The client now verifies the public key from user and saves
4682 it into ~./silc/serverkeys/ directory.
4684 Added into: clientutil.[ch]: silc_client_verify_server_key.
4686 * Changed SKE protocol's silc_ske_initiator_finish function
4687 to accept callback function that verifies the received public
4688 key. Removed old silc_ske_verify_public_key function.
4690 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4693 silc_pkcs_private_key[_data]_set.
4695 * Made the password and public authentication more cleaner in
4696 server's protocol.c.
4698 * Removed historic and obsolete protocol `channel_auth' from
4699 both client and server.
4701 * Removed wrong way of sending command status messages from
4702 server to client in server's command.c. The old way violated
4703 protocol specification.
4705 Changes to silccore/silccommand.[ch]: removed
4706 silc_command_encode_status_payload -> not needed anymore,
4707 changed silc_command_encode_payload_va to accept extra
4708 argument on variable argument list. The argument type must
4709 now be provided to the function. Also, added new function:
4710 silc_command_encode_reply_payload_va which is same as
4711 normal command_encode_payload_va except command status type
4712 is provided as extra argument.
4714 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Added ~./silc directory handling. The directory includes the
4717 public and private keys for the client.
4719 Added silc_client_check_silc_dir, silc_client_create_identifier
4720 and silc_client_load_keys.
4722 * Implemented SILC protocol compliant public key. Added public
4723 and private key saving to and loading from files.
4725 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4726 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4727 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4728 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4729 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4731 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4732 silc_pkcs_load_[public/private]_key.
4734 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Added silc_server_get_route (route.[ch]) to get connection
4737 data for the fastest route for given ID.
4739 * Implemented INVITE command on client and server. The command
4740 were re-defined in the SILC Protocol Specification and the
4741 implementation now complies with the specification.
4743 * Implemented PING command on client and server.
4745 * Implemented NAMES command on client and server. The server side
4746 supports currently only normal server not router server yet.
4747 Some changes to NAMES definition in SILC protocol specification.
4749 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Implemented LEAVE command on client and server.
4753 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4754 again. This change was made to the protocol as well. Server
4755 should not violate the protocol specification anymore.
4757 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4760 was tested. SOCKS4 was not but should work anyway.
