3 * Fixed a double free in disconnection in the server. Affected
4 file is silcd/server.c.
6 * Fixed the lib/silcske/groups.c to work now also with GMP
7 MP library. The string conversion did not work when using
8 specific base and the base is indicated in the string as well.
10 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Changed the key material distribution function in case when
13 the hash output is too short. The data is now concatenated
14 a bit differently than it used to. Made the change to the
15 SKE protocol specification.
17 * Added better GMP detection to configure.in.pre. A patch
20 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
22 * Fixed a minor bug in SKE that might cause some problem on
23 some platforms. Affected file lib/silcske/silcske.c.
25 * Added the cookie checking for initiator in the SKE. It checks
26 that the responder returns the sent cookie unmodified. The
27 affected file is lib/silcske/silcske.c. Added new SKE
28 error type INVALID_COOKIE that can be sent during the
29 negotiation. Fixed some memory leaks as well.
31 * Added the "invalid cookie" error message to Irssi SILC client's
34 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
36 * Added `task_max' field to the SilcClientParams to indicate
37 the maximum tasks the scheduler can handle. If set to zero,
38 default values are used. Affected file lib/silcclient/silcapi.h.
40 * Fixed memory leaks in silc_client_close_connection. Affected
41 file lib/silcclient/client.c.
43 * Added silc_client_del_client_entry to client library to free
44 all memory of given client entry. Affected file is
45 lib/silcclient/idlist.[ch].
47 * Added new functions silc_client_del_channel and
48 silc_client_del_server to delete channel and server entries.
49 Affected file lib/silcclient/[silcapi.h/idlist.c].
51 * Removed silc_client_del_client_by_id from silcapi.h.
53 * Fixed the INFO command to return the server's own info
54 correctly when querying by Server ID. Affected file is
57 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
59 * Removed the non-blocking settings in WIN32 code in the
60 silc_sock_[read/write] and added SleepEx instead. Affected
61 file lib/silcutil/win32/silcwin32sockconn.c. The availability
62 of input data is now checked with FIONREAD and ioctlsocket.
64 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
66 * Call silc_schedule_task_del_by_context in the
67 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
68 Affected file lib/silccore/silcprotocol.c.
70 * Call silc_protocol_cancel for active protocols in the
71 silc_server_close_connection if the funtion
72 silc_server_free_sock_user_data has not been called.
73 Affected file silcd/server.c.
75 * Generic tasks cannot be deleted using the del_by_fd
76 task deleting function since generic tasks does not match
77 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
79 * Added a notion to SILCOPER help file that the SILCOPER works
80 only on router server, not on normal server.
82 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
84 * Added for WIN32 support for the new scheduler as well.
85 Affected file lib/silcutil/win32/silcwin32schedule.c.
87 * Fixed the SHA1 implementation to work on various platforms.
89 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
91 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
92 API. It is part of the scheduler now. Everything else is
93 as previously but some functions has changed their names.
94 Checkout the lib/silcutil/silcschedule.h for the interface.
95 Updated all applications to use the new interface. Affected
96 files are lib/silcutil/silcschedule.[ch].
98 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
100 * Found a bug in the SKE implementation. The HASH value,
101 specified by the protocol, was not computed correctly. The
102 public key of the responder was not added to the computation
103 even though it is mandatory. Affected file lib/silcske/silcske.c.
104 This unfortunately causes incompatibilities with older
107 * Added WIN32 specific network init and uninit functions:
108 silc_net_win32_init and silc_net_win32_uninit to init and uninit
109 the Winsock2. Affected file lib/silcutil/silcnet.h and
110 lib/silcutil/win32/silcwin32net.c.
112 * Set the socket always to nonblocking mode on WIN32 after
113 reading data or writing data. Affected file is
114 lib/silcutil/win32/silcwin32sockconn.c.
116 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Fixed various compilation problems under WIN32. Affected
119 files lib/silcutil/win32/silcwin32thread.c and
120 lib/silcutil/win32/silcwin32schedule.c.
122 * Removed all _internal.h #includes from public header
123 files. Internal headers must never be included from
126 Removed also the lib/silcske/payload_internal.h file.
128 * All include files that may be needed (public and some others
129 included by the public headers) by application developers are
130 now copied to the ./includes directory. It does not copy any
131 internal headers. Affected file Makefile.defines.pre and all
132 Makefile.am's under lib/ and subdirs.
134 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
136 * Do not change the ~/.silc directory's permissions automatically.
137 Affected file irssi/src/silc/core/clientutil.c.
139 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
141 * Do not cancel the protocol in silc_server_close_connection
142 it might cause recursion. Now cancelled in the function
143 silc_server_free_sock_user_data. Affected file silcd/server.c.
145 * Fixed the silc_server_remove_clients_by_server to regenerate
146 the channel keys correctly finally. Added also new function
147 silc_server_remove_clients_channels to actually do it.
148 Affected file silcd/server.c.
150 * Fixed the silc_server_new_channel to not crash by giving
151 wrong router to the new channel. Affected file is
152 silcd/packet_receive.c.
154 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
156 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
157 which is given as argument to the silc_client_alloc now.
158 It can be used to configure the client and set various parameters
159 that affect the function of the client.
161 * The USERS command in server did not check whether the channel
162 is private or secret. Affected file silcd/command.c.
164 * Added new argument to the USERS command in protocol specification.
165 The USERS command now can take the channel name as argument
166 as well. Added support for this in client and server and
167 updated the protocol specs.
169 * Completed the GETKEY command in client. It can be now used
170 to fetch also servers public key not only some clients.
171 Affected files lib/silcclient/command[_reply].c.
173 * Added silc_client_get_server to return server entry by the
174 server name. Affected files lib/silcclient/silcapi.h and
177 * Redefined the IDENTIFY command in protocol specification to be
178 more generic. It now can be used to query information about
179 any entity in the SILC Network, including clients, servers and
180 channels. The query may be based either the entity's name
181 or the ID. Added support for this in both client and server.
183 Affected files silcd/command.c and lib/silcclient/command.c
186 * Optimized the WHOIS and WHOWAS commands in the server. Removed
187 the _from_client and _from_server functions. Affected file
190 * Added silc_client_get_channel_by_id_resolve to the file
191 lib/silcclient/silcapi.h to resolve channel information by
192 its ID. Added also silc_client_get_channel_by_id that
193 does not resolve it from the server.
195 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
197 * Added SilcServerEntry context into the client library
198 to represent one server. The INFO command now allocates
199 these to save the resolved server info. For now on the
200 client library will also keep information about servers,
201 connected and resolved with INFO.
203 The INFO command now allocates the SilcServerEntry context
204 and saves the server info there. The COMMAND_REPLY in
205 the INFO now returns the parameters to application in
206 same order as defined in the protocol specification.
208 The entries are cached in the client->server_cache.
210 * The INFO command is now issued after received the Client ID
211 from the server. Affected file lib/silcclient/client.c.
213 * The CMODE_CHANGE notify may now return also an SilcServerEntry
214 to the application as the mode changer might be server.
215 It is guaranteed that NULL is not returned anymore to the
216 application. Affected file lib/silcclient/client_notify.c.
218 The ID Type is now also passed to the application so that
219 it can check whether the returned entry is SilcClientEntry
222 Added new function silc_client_get_server_by_id to return
223 the server entry by ID. Affected files are the
224 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
226 * Do not create the channel in the Irssi SILC Client when issuing
227 the JOIN command but when received the sucessful JOIN command
228 reply. Otherwise the channel might get created even though we
229 could not join it. The Affected file is
230 irssi/src/silc/core/[silc-channels.c/client_ops.c].
232 * Fixed a channel joining bug in router. The router must also
233 check the channel modes, invite and ban lists etc. when serving
234 the JOIN command sent by normal server. Affected file is
235 silcd/command.c. The router now resolves the client's
236 information from the server who sent the JOIN command if it
237 does not know it, and processes the JOIN command only after
240 * Changed the SilcCommandCb to take new argument; void *context2.
241 Affected file lib/silccore/silccommand.h
243 The second argument in the command callbacks in the server now
244 includes the SilcServerCommandReplyContext if the command was
245 called as pending command callback from the command reply.
246 Otherwise it is NULL. When called as pending the status of the
247 command reply will be checked and if it was erronous the
248 error will be sent to the original sender of the command.
249 This way the client always receives the error messages even
250 though the server was actually the one who received the error
251 when it resent the command to router, for example. Affected
252 files silcd/command[_reply].[ch].
254 * Fixed sending WHOWAS command's error message to client if
255 the requested client could not be found. It was missing.
258 * Changed the CMODE and CUMODE commands reply arguments in the
259 protocol specification. The Channel ID is now sent in both
260 of the commands to identify the channel. Implemented this
261 new feature to the client and server. Affected files
262 lib/silcclient/command_reply.c and silcd/command.c.
264 * Made better checks for invite and ban lists in the JOIN
265 command in server. Affected file silcd/command.c.
267 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
269 * The server now performs the incoming host IP/DNS lookup
270 using the silc_socket_host_lookup and thus does not block
271 the server anymore. Affected file silcd/server.c.
273 * Completed the multi-thread support for SILC Scheduler in
274 the lib/silcutil/silcschedule.c.
276 * Fixed the configure.in.pre to detect the pthread correctly
279 * Fixed a deadlock in silc_task_queue_wakeup in the file
280 lib/silcutil/silctask.c.
282 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
284 * Added new function silc_schedule_wakeup that is used in
285 multi-threaded environment to wakeup the main thread's
286 schduler. It needs to be used when a thread adds a new task
287 or removes a task from task queues. After waking up, the
288 scheduler will detect the task queue changes. If threads
289 support is not compiled in this function has no effect.
290 Implemented the wakeup mechanism to both Unix and WIN32
291 systems. Affected files are lib/silcutil/silcschedule.[ch],
292 lib/silcutil/unix/silcunixschedule.c and the
293 lib/silcutil/win32/silcwin32schedule.c.
295 * Added new function silc_task_queue_wakeup to wakeup the
296 scheduler by the specified task queue. Affected file
297 lib/silcutil/silctask.[ch].
299 * The silc_socket_host_lookup_start now wakes up the scheduler
300 after adding the timeout task. Affected file is
301 lib/silcutil/silcsockconn.c.
303 * The silc_socket_host_lookup is synchronous now if the threads
304 support is not compiled in. However, the callback is still
305 called asyncronously through the scheduler, anyway. Affected
306 file lib/silcutil/silcsockconn.c.
308 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Added new function silc_socket_host_lookup to perform
311 asynchronous IP and FQDN lookups for the socket connection.
312 Affected files lib/silcutil/silcsockconn.[ch].
314 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
316 * Added SILC_MUTEX_DEFINE to define the mutex on environments
317 that may or may not compile the mutex support in.
319 Changed the silc_mutex_alloc interface. It allocates the
320 mutex now to the sent pointer and returns TRUE or FALSE.
322 Affected file lib/silcutil/silcmutex.h.
324 * Wrote the SILC Task Queue interface to support multi-threads.
325 Affected file lib/silcutil/silctask.[ch].
327 * Wrote the SILC Scheduler to support multi-threads. Affected
328 file lib/silcutil/silcschedule.c.
330 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
332 * Implemented the SILC Mutex API and SILC Thread API for WIN32
333 in lib/silcutil/win32/.
335 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Defined SILC Mutex API and SILC Thread API and implemented
338 them for Unix. Affected files are
339 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
340 lib/silcutil/unix/silcunixmutex.c and
341 lib/silcutil/unix/silcunixthread.c.
343 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
345 * Fixed the silc_server_remove_clients_by_server's channel
346 key re-generation. The hash table handling was incorrect
347 and would not work with many channels. Affected file is
350 * Fixed some memory leaks around the server code.
352 * Rewrote the silc_server_get_users_on_channel to support IPv6
353 based Client ID's. Affected file silcd/server.c.
355 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
356 specification. However, a separate document must be written
357 to define the detailed signing procedure and the payload
358 associated with the flag. Defined the flag to the
359 lib/silccore/silcchannel.h as well.
361 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Changed the dynamic tables to static size tables in the
364 lib/silccrypt/silchmac.c.
366 * Removed GCC dependencies from the code. A patch by cras.
368 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
370 * Do not show the error "Error receiving packet bla bla"
371 in server if it really was not an error (-2 means that reading
372 is pending). Affected file silcd/server.c.
374 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
376 * Fixed a possible crash in silc_server_remove_clients_by_server
377 in silcd/server.c. Fixed there also some memory leaks.
379 * Fixed the silc_idlist_replace_client_id. It could replace
380 wrong key in the hash table. Affected file silcd/idlist.c.
382 * Do not check whether there are global users on the channel
383 if the channel->global_users is FALSE. Affected functions
384 silc_server_remove_from_one_channel and
385 silc_server_remove_from_channels in silcd/server.c. Also,
386 do not check if the removed client is local as we can be
387 sure that global client was not removed from the channel
388 and checking for global users is not needed.
390 * The silc_server_remove_clients_by_server now re-generates
391 the channel keys correctly for those channels that had
392 clients removed from them. Affected file silcd/server.c.
394 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
396 * Found the reason of random crashes in the server. We weren't
397 ignoring the SIGPIPE signal (which can be sent in write())
398 and it crashed the server. Affected file silcd/silcd.c.
400 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Assure that sock->user_data is not NULL in the function
403 silc_server_packet_send in silcd/packet_send.c.
405 * Disconnect the remote connection if it could not be added
406 to any ID lists in the server. The affected file is
409 * Check in silc_server_packet_send[_real/dest] that the
410 socket is not disconnecting and ignore the data if it is.
411 Affected file silcd/packet_send.c.
413 * Define inline to __inline on native WIN32 compilation.
414 Affected file includes/silcwin32.h.
416 * Added some explicit type casts for inline code since MSVC
417 require them. Affected files lib/silcutil/silcbuffer.h,
418 lib/trq/silcdlist.h and lib/trq/silclist.h.
420 * Print warning in log files from now on if the packet
421 decryption fails. Affected file silcd/server.c.
423 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
425 * Changed the `say' client operation's interface to accept
426 new `type' argument to indicate the type of the message sent
427 by the library. The application may filter the library's
428 messages according the type. The affected file is the
429 lib/silcclient/silcapi.h.
431 * Added two new functions to lib/silcclient/silcapi.h:
432 silc_client_del_client and silc_client_del_client_by_id.
433 Affected file lib/silcclient/idlist.c.
435 * Moved the clientincludes.h from includes/ to silc/ and
436 serverincludes.h from includes/ to silcd/.
438 * The modes for the CMODE and CUMODE are now passed as
439 uint32 for application with COMMAND_REPLY. The affected
440 file is lib/silcclient/command_reply.c.
442 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
444 * /WHOIS without arguments shows client's own information.
445 Affected file lib/silcclient/command.c.
447 * Changed PING to not accept any arguments. The specs
448 says that client can ping only the connected server so
449 requiring an argument is not needed. Affected file is
450 lib/silcclient/command.c.
452 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
454 * Fixed a fatal bug in private message sending and reception
455 encryption and decryption when using private message keys.
456 The implementation was incorrect and did not follow the
457 specification. It causd that some of the message were
458 lost since it did not use the sending and receiving keys
459 as the protocol suggests. This has been fixed and will cause
460 incompatibilities with older clients when sending private
461 message encrypted with private message keys. Affected files
462 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
463 and various other in Irssi SILC Client.
465 Added `responder' boolean argument to the functions
466 silc_client_add_private_message_key[_ske] to indicate when
467 the key is added as responder or initiator of the key
470 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Removed the silc_ske_check_version function and created
473 a SilcSKECheckVersion callback. Added also a function
474 silc_ske_set_callbacks that is now used to set all SKE
475 callbacks. The callback functions are not given to
476 the SKE functions anymore, but this function is used to
479 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
481 * Added `silc_version' argument to the silc_client_alloc
482 to define the version of the application for the library.
483 The library will use the version string to compare it
484 against the remote host's (usually a server) version
485 string. Affected file lib/silcclient/silcapi.h
487 * Added the KE protocol context to Key Agreement context
488 in client library so that we can abort the SKE if it
489 is in process when we get timeout. Affected file is
490 lib/silcclient/client_keyagr.c.
492 * Do not resolve the client ID forever if it returns in the
493 first time that such client does not exist. This was done
494 for example with private message. Affected file is
495 lib/silcclient/client_prvmsg.c.
497 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Do not add regex.h for WIN32. The affected file
500 includes/silcincludes.h.
502 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
503 not work yet 100%. It generates the DLL's automatically
504 when compiling with --with-win32 under cygwin.
506 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
508 * lib/contrib/regex.c is not compiled on WIN32.
510 * Added silc_net_get_socket_opt function to the
511 lib/silcutil/silcnet.h.
513 * Added includes/silcwin32.h for WIN32 specific includes
516 * Do not use ptime structure or any of the posix process
517 functions on WIN32 in lib/silccrypt/silrng.c.
519 * Added silc_gettimeofday to provide generic function
520 for struct timeval on all platforms. Added the function
521 to lib/silcutil/silcutil.h.
523 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Moved the lib/silccore/silcsockconn.[ch] to the utility
526 library as they clearly belong there. As a plus side we
527 can make the actual socket connection routines platform
530 Added also new generic function silc_socket_read and
531 silc_socket_write (that used to be silc_packet_[read/write].
532 The implementation of these are platform specific.
534 * Added WIN32 specific routines of silc_socket_[read/write]
535 to lib/silcutil/win32/silcwin32sockconn.c.
537 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
539 * Added preliminary support for native WIN32 compilation under
540 cygwin (using the -mno-cygwin option for GCC) to the
541 ./configure.in.pre. The --with-win32 now prepares the
542 compilation for native WIN32.
544 * Rewrote the SILC Scheduler interface in the file
545 lib/silcutil/silcschedule.h. The scheduler is now context
546 based and does not have anymore any global static scheduler.
547 Moved the Unix scheduler to the lib/silcutil/unix/ directory
548 and created lib/silcutil/win32 directory for WIN32 based
551 * Added Unix specific network routines to the
552 lib/silcutil/unix/silcunixnet.c and the old
553 lib/silcutil/silcnet.c includes now only generic routines.
555 Added WIN32 specific network routines to the
556 lib/silcutil/win32/silcwin32net.c.
558 * Added Unix specific utility functions from the
559 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
561 * Added WIN32 SILC Scheduler to the file
562 lib/silcutil/win32/silcwin32schedule.c. The code is of course
565 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Do not handle JOIN notify in the server if the target client
568 is not registered (idata->registered == FALSE). The affected
569 file is silcd/packet_receive.c.
571 * Update the nickrec->founder in event_cumode in the Irssi SILC
572 client. Affected file irssi/src/silc/core/silc-channels.c.
574 * Fixed the CUMODE_CHANGE notify handling in the server when
575 server and router are announcing their clients on channels.
576 Now the mode changes are saved and notified correctly. The
577 affected file is /silcd/packet_receive.c.
579 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
580 They really did not replace the cache entry in the ID Cache.
581 Now they do that. Affected file silcd/idlist.c.
583 * Fixed the KICK notify handling in the Irssi SILC client to
584 update the channel records so that the kicked client does not
585 appear to be on the channel. The affected file is
586 irssi/src/silc/core/silc-channels.c.
588 * Always update the conn->current_channel when executing command
589 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
591 * Fixed the KILL notify handling in Irssi SILC client to remove
592 the killed client on all channels.
594 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Fixed the silc_parse_command_line to remove extra spaces
597 from the start and end of the arguments. Affected file is
598 lib/silcutil/silcutil.c.
600 * Cancel and free any active protocol in the function
601 silc_server_close_connection. Affected file silcd/server.c.
603 * Cancel and free any active protocol in the function
604 silc_client_close_connction. Affected file is
605 lib/silcclient/client.c.
607 * Do not execute the KILL command for clients that are in
608 history (ie. they are not in the network). Affected file is
611 * Fixed KILL notify handling, client does not crash anymore.
612 Affected file irssi/src/silc/core/silc-channels.c.
614 * Reduced the default packet buffer size from 2048 to 1024 in
615 lib/silccore/silcpacket.c.
617 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
618 counter to the SKE context that is incresed when the SKE library
619 performs async operation outside the library. If the outside
620 process frees the SKE context and FREED status will be set
621 and the library will detect after the sync operation that the
622 libary is freed. The affected files are
623 lib/silcske/silcske[_status].[ch].
625 * Resolve the client entry information in the function
626 silc_client_channel_message to assure that NULL pointer is not
627 passed as client entry to the application. */
629 * Fixed the task timeout calculation to assure that there is
630 never negative timeouts. The affected file is
631 lib/silcutil/silcschedule.c.
633 * Fixed the channel user mode notification sending in server.
634 It was sent point-to-point to the router (or to server by router)
635 but it needs to be destined to a channel. The routines now
636 supports sending the channel user mode notifys to the channels
637 when announcing clients and channels. Affected files are
638 silcd/server.c and silcd/packet_receive.c.
640 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
641 It did not actually replace the old channel entry in the cache.
642 Affected file lib/silcclient/client_notify.c.
644 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Fixed a possible crash in silc_packet_send_prepare. It now
647 assures always that there is enough space in the buffer and
648 at the tail area of the buffer (for MAC).
650 Fixed the inbound buffer reallocation in silc_packet_read.
651 It was old code and did not handle the reallocation correctly.
654 The affected file is lib/silccore/silcpacket.c.
656 * Fixed buffer overflow in silc_parse_nickname in the file
657 lib/silcutil/silcutil.c.
659 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * make install generates new server keys only if there is not
664 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
666 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
667 Added check that if the NOREPLY is set then we will not send
668 the away message. This avoids infinite loop of away messages
669 if both clients are away. The affected file is
670 lib/silcclient/client_prvmsg.c.
672 * Fixed client crash if /NICK was given without arguments.
673 Affected file lib/silcclient/command.c.
675 * Server does not send the invite list in INVITE command back
676 to the client if the list was not altered. Added this notion
677 to the protocol spec as well. Affected file silcd/command.c.
679 Fixed possible crash in INVITE command by checking the
680 value of silc_server_get_client_route command.
682 * Fixed the INVITE notify type handling. The arguments are now
683 taken in correct order and client does not crash. The affected
684 file is irssi/src/silc/core/silc-channels.c.
686 Removed the "Inviting xxx to channel" message from the
687 client library away and let the application handle it.
688 Affected file lib/silcclient/command.c. Added that message
689 to Irssi SILC client's message formats.
691 * Fixed CMODE command crash in client. It now checks the
692 amount of arguments correctly and does not crash. The affected
693 file is lib/silcclient/command.c.
695 * Do not create new channel automatically in silc_channels_join
696 but check whether the channel by that name already exists.
697 Affected file irssi/silc/core/silc-channels.c.
699 * Do not send the SERVER_SIGNOFF to router if the disconnected
700 entity was the router. Affected file silcd/server.c.
702 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
703 SILC client as it was missing from there.
705 Added the handling of the KICK notify to the Irssi SILC client
706 as it was missing. Added "you have been kicked" message to
707 Irssi SILC client's message modules formats.
709 Added the handing of the KILL notify to the Irssi SILC client
710 as it was missing. Added the kill message module formats
713 The affected file is irssi/src/silc/core/silc-channels.c.
715 * The router did not save the channel mode the server announced.
716 Affected file silcd/packet_receive.c.
718 * Fixed a possible crash in INFO command in server. If the
719 server did not provide the server info it crashed. Affected
720 file silcd/command.c.
722 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Fixed the GETKEY command in the server to check also the
725 global list. Otherwise the GETKEY would not work correctly
726 in normal SILC server. Affected file silcd/command.c.
728 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Fixed GETKEY crash, it crashed if the command did not succseed.
732 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
735 is now real and not just an macro interface to GMP.
737 Removed the entire GMP from the source tree and imported new
738 NSS MPI library instead. Reason for removing GMP is that it is
739 extremely large and compiles extremely slow. The NSS MPI
740 is only a few files and compiles in less than 10 seconds.
741 The speed is also about the same as GMP. The MPI is imported
744 If the system has GMP installed we will still use the GMP.
745 If it is not then the NSS MPI will be compiled.
747 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Merged a long nickname (127 characters long) crash bugfix from
750 Irssi CVS tree. Affected file irssi/src/core/misc.c.
752 * Merged a freed memory reference bugfix from Irssi CVS tree.
753 Affected file irssi/src/core/commands.c.
755 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Added the server's public key sving and verification to the
758 server when performing the SKE. This was missing and the
759 remote server's (or router's) public key was accepted without
760 checking whether we have it previously or trust it at all.
761 Affected file silcd/protocol.c.
763 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Check in the silc_server_timeout_remote if protocol is active
766 and make sure that the protocol's final callback is called so
767 that all memory if freed. Affected file silcd/server.c.
769 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * silc_server_whois_send_reply crashed the server if the nickname
772 was 127 characters long. Affected file silcd/command.c.
774 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Added sanity check to the silc_server_new_client. If the hostname
777 is provided inside username then check that the provided hostname
778 really is the same as the resolved one. If the hostname was not
779 resolved then check it from the public key. Affected file is
780 silcd/packet_receive.c.
782 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
783 if the server disconnected us and the connection is not valid
784 anymore. Affected file irssi/src/silc/core/silc-channels.c.
786 * Moved the silc_client_[chmode|chumode|chumode_char] away from
787 the library to the lib/silcutil/silcutil.[ch].
789 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Close log file after open. Affected file
792 lib/silcutil/silclog.c.
794 * Check whether sock == NULL in silc_client_send_packet and return
795 if it is. Affected file lib/silcclient/silcclient.c.
797 * Check rec->entry == NULL in the Irssi SILC Client before
798 sending the channel message. Affecte file is
799 irssi/src/silc/core/silc-servers.c.
801 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Merged a splitted window bugfix from Irssi CVS tree. The
804 affected file is irssi/src/fe-text/textbuffer-view.c.
806 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
807 It did not print nickname.
809 * Improved the distributions system a bit.
811 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
813 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
814 irssi/src/fe-text/gui-window.c.
816 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
817 to in-active server. The affected file is
818 irssi/src/silc/core/client_ops.c.
820 * Resolve the client in USERS command reply if the entry does
821 not have username resolved. The affected file is
822 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
823 command to WHOIS command to really resolve stuff. The USERS
824 is not used any more in any critical section so WHOIS can
825 be used even though it might be slower than IDENTIFY.
827 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
830 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Changed the protocol API a bit more consistent in the
833 lib/silccore/silcprotocol.[ch].
835 * Changed the following headers to ROBODoc format:
837 lib/silccore/silcpayload.h
838 lib/silccore/silcprotocol.h
839 lib/silccore/silcsockconn.h
841 All core library headers are now formatted.
843 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Fixed a bug in Irssi SILC client; do not show that you are
846 server/router operator if you really are not. Affected file is
847 irssi/src/silc/core/client_ops.c.
849 * Renamed silc_command_free_payload to silc_command_payload_free.
850 Affected file lib/silccore/silccommand.h
852 * Added silcmath.h to include the prototoypes of various routines
853 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
856 * Changed the following headers to ROBODoc format:
858 lib/silccore/silcchannel.h
859 lib/silccore/silccommand.h
860 lib/silccore/silcid.h
861 lib/silccore/silcidcache.h
862 lib/silccore/silcmode.h
863 lib/silccore/silcnotify.h
864 lib/silccore/silcpacket.h
865 lib/silcmath/silcmath.h
867 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Added checking to the server code not to start the server if
870 ciphers and stuff are not configured properly. Affected files
871 silcd/serverconfig.[h] and silcd/server.c.
873 * Changed the layout of the header files of the public interfaces
874 in the SILC libraries. The new layout supports ROBODoc
875 documentation tool (and some others) so that it is easy to create
876 a library reference manual. All the other headers and source
877 code must still follow the CodingStyle document. Also source
878 code must not include these ROBODoc stuffs, only the headers.
879 Furthermore, all public interface headers must now be named
880 by using `silc' prefix, example: silcapi.h, silccipher.h.
881 Some files were renamed due to this. All the other headers
882 must not be used as public interfaces. I will update the
883 CodingStyle document later. Changed following headers, so far:
885 lib/silcclient/silcapi.h
886 lib/silccore/silcauth.h
887 lib/silccore/silcprivate.h
888 lib/silccrypt/silcdh.h
890 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Removed silc_client_packet_send_flush from the client library
895 as it is not needed. Affected file lib/silcclient/client.[ch].
897 * Added printing of message of unresolved authentication method
898 to the Irssi SILC client. Added it to the module formats.
899 Removed the same message from the client library.
901 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
903 * Added new distribution feature, DISTLABEL. Every distribution
904 can define own preprocessor label that can be used in the
905 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
906 file distributions, acconfig.h.pre and prepare.
908 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Added Makefile.defines_int to include the actual definitions
911 for Makefile.defines.in. Tested the new distribution system,
912 created distributions and tested installation.
914 * Added AWAY message printing to the Irssi SILC client. Added
915 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
917 * Added SCONNECT command to call the SILC's CONNECT command.
918 Cannot use CONNECT directly since Irssi uses that internally.
919 Affected file irssi/src/silc/core/silc-servers.c.
921 Added ACTION local command. It is same as ME command but takes
922 the channel as mandatory argument.
924 Rewrote some of the Irssi's help files to suite for SILC
927 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Added Makefile.defines[.in] that should for now on be included
930 in all Makefile.am file in the source tree. That file includes
931 all common compilation definitions for SILC source tree.
933 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Minor changes to the ./prepare script to change the package
936 name according the distribution name to the configure.in.
938 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Created new distribution system. Added file `distributions'
941 that defines all the distributions that can be created out of
942 the SILC source tree. The ./prepare script now reads that
943 file to determine how to prepare the distributions. The
944 first argument to the ./prepare is the name of the distribution
945 and second is the version of the distribution. If given
946 without arguments it creates the default (toolkit) distribution
947 with the default version (defined in ./prepare).
949 All Makefile.am files that are subject to the distributions
950 are now named as Makefile.am.pre. These are ./Makefile.am
951 and lib/Makefile.am. Others may be changed later.
953 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Added invite list, ban list, some key management and connection
956 error message printing to module formats in the Irssi SILC client.
958 * Added new silc_client_set_away_message to set the away message
959 that is back to the person who sent private message. The
960 affected file lib/silcclient/silcapi.h and the
961 lib/silcclient/client_prvmsg.c.
963 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Fixed the private message sending in the Irssi SILC client,
966 added local command KEY to the Irssi SILC client.
968 Added key management and key agreement message formats to the
969 irssi/src/fe-common/silc/module-formats.[ch].
971 Added USERS (alias WHO) printing, server/router operator
972 indication and LIST command printing to the module formats.
974 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Fixed channel joining notify handling, cumode notify handling
977 from Irssi SILC client.
979 * Added SILC specific module-formats to the Irssi SILC client so
980 that SILC specific message hilighting, colors etc is possible.
981 Affected file irssi/src/fe-common/silc/module-formats.[ch].
983 Added channel mode, channel user mode, actions, notices,
984 whois and whowas printing to the the module-formats.c.
986 * Fixed a bug in channel deletion in the server. The channel
987 is not left to the cache even if the channel founder auth mode
988 is set when there are no users anymore on the channel. Affected
991 * The silc_net_localhost now resolves the entire hostname including
992 the domain name. Affected file lib/silcutil/silcnet.c.
994 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
996 * Changed the ask_passphrase client operation to be ascynchronous.
997 It has now a completion callback and a context that the
998 application must call after it has got the passphrase from
999 the user. Affected files lib/silcclient/silcapi.h,
1000 lib/silcclient/protocol.c, lib/silcclient/command.c and
1003 Added SilcAskPassphrase callback that the application calls
1004 to deliver the passphrase to the library.
1006 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1007 The public key verification and especially a certificate
1008 verification is asynchronous procedure.
1010 Added new SILC_SKE_STATUS_PENDING status to indicate the
1011 request is pending and a callback will be called to finalize
1014 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1015 indicate that remote end did not send its public key (or
1016 certificate), even though we require it. Added check for this
1017 condition in the SKE. This was a security bug, now fixed.
1019 Defined new SilcSKEVerifyCbCompletion callback that is called
1020 when the verification process is completed.
1022 The affected files lib/silcske/silcske_status.h and
1023 lib/silcske/silcske.[ch].
1025 * Changed the verify_public_key client operation to be async
1026 as well. Defined SilcVerifyPublicKey callback that is used to
1027 indicate the success of the public key verification process.
1029 Changed the server and client to use the new async client
1032 * Changed the Irssi SILC client's internal scheduler to be called
1033 twice as many times as it used to be. As a result the client
1034 should be a bit faster now. Affected file is
1035 irssi/src/silc/core/silc-core.c.
1037 * Added support to Irssi SILC client of asynchronous public key
1038 verification and passphrase inquiry. Affected file is
1039 irssi/src/silc/core/silc-core.c.
1041 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1043 * Do not say "You have left channel %s" in client library.
1044 Moved it to the application. Affected files are
1045 lib/silcclient/command.c and silc/client_ops.c.
1047 * Fixed silc_client_get_clients. Command context was not
1048 duplicated and was freed memory in the callback. Affected
1049 file lib/silcclient/idlist.c.
1051 * Do not say "you are now talking..." on JOIN command in the
1052 client library. The appliation must handle it.
1054 * Do not say ".. changed topic to" in command reply in the
1055 client libary. The application must handle it.
1057 * Fixed TOPIC command sending in the client library.
1059 * Fixed a memory leak in silc_client_command_free in the file
1060 lib/silcclient/command.c.
1062 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Imported a modified version of Irssi client to the source tree.
1065 The Irssi will be used to create a new client called
1066 Irssi SILC. Imported to irssi/.
1068 Added silc_core_init_finish function to the Irssi. Affected
1069 file irssi/configure.in.
1071 A lot changes in the Makefile.ams around the irssi tree.
1073 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Do not rehash if the new size is same as the old size of the
1076 hash table, in the silc_hash_table_rehash*. The affected file
1077 lib/silcutil/silchashtable.c.
1079 * Replaced hash_table_del_by_context calls from the server
1080 (when channel->user_list and client->channels) to the
1081 hash_table_del as it is sufficient and faster.
1083 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Added silc_hash_table_list, silc_hash_table_get and the
1086 SilcHashTableList structure to provide an alternative way to
1087 traverse the hash table. The affected files are
1088 lib/silcutil/silchashtable.[ch].
1090 * Changed the server's idlist routines to use the hash table
1091 routines to optimize the code.
1093 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Replaced the client entry's `channel' list and channel entry's
1096 `user_list' list to hash tables for optimized lookup. Changed
1097 the code to use the hash table interface around the code.
1098 Affected file lib/silcd/idlist.[ch].
1100 * Added `auto_rehash' boolean argument to the function
1101 silc_hash_table_alloc to indicate whether the hash table should
1102 auto-rehash when it thinks is appropriate time. It will
1103 increase the hash table size if the there is twice as much
1104 entries in the table than the size of the table, and will
1105 decrease the size if there are twice as less entries than
1106 the size of the table.
1108 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1112 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * silc_idcache_purge_by_context deletes the entry now by context
1115 as it is supposed to do. Affected file lib/silccore/idcache.c.
1117 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1118 client is not anymore valid (WHOWAS givens the info) and not
1119 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1121 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1123 * Removed the `data' and `data_len' arguments from the ID Cache
1124 interfaces and added `name' argument. ID Cache does not handle
1125 anymore the binary data only a names associated with given ID.
1127 * When hashing a Client ID with silc_hash_id the entire ID is
1128 not hashed anymore, instead only the hash of the Client ID is
1129 hashed. This way we can access the Client ID from the cache
1130 with Client ID but with the hash of the ID (which is a hash of
1131 the nickname) as well without any difference in performance.
1133 Added also silc_idcache_find_by_id_one_ext to do one on one
1134 searching when we have the actual ID. Added also function
1135 silc_hash_client_id_compare. The affected files are
1136 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1138 * When hashing the name associated with a ID it is always done
1139 in lowercase. This way we can access the cache without worrying
1140 about case-sensitivity, even though, for example nicknames are
1143 * Fixed a bug in server with channel message sending. It put
1144 wrong ID type as destination ID. The affected file
1145 silcd/packet_send.c.
1147 * silc_idcache_del_by_context now deletes from all hash tables
1148 by context. Affected file lib/silccore/idcache.c.
1150 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Changed the client library to use the new ID Cache interface.
1153 Changes around the source tree.
1155 * Added silc_hash_table_rehash_ext to rehash with specific
1156 hash function. Affected file lib/silcutil/silchashtable.[ch].
1158 * Added silc_hash_string_compare to compare two strings in the
1159 hash table. Affected file lib/silcutil/silcutil.[ch].
1161 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Added new function silc_idcache_del_by_context into the
1164 lib/silccore/idcache.[ch].
1166 * Changed the server's ID list routines to use the new ID Cache
1167 interface. Changes around the source tree.
1169 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Added silc_hash_table_del[_by_context]_ext functions in to the
1172 lib/silcutil/silchashtable.[ch].
1174 Removed silc_hash_table_find_all* routines and added new
1175 silc_hash_table_find_foreach to replace them.
1177 Added silc_hash_table_replace_ext function as extended
1178 replacing function. Separated the simple hash table interface
1179 from the extended hash table interface in the file
1180 lib/silcutil/silchashtable.h.
1182 * Fixed minor bugs and changed it to use some of the new
1183 hash table functions in lib/silccore/idcache.c
1185 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Added new function silc_hash_table_find_all to return all keys
1188 in the hash table by the specified key. As the hash table is
1189 collision resistant it also makes it possible to have several
1190 duplicate keys in the hash table. This function may be used to
1191 find all of the keys from the hash.
1193 Added user_context arguments to the SilcHashFunction,
1194 SilcHashCompare and SilcHashDestructor to deliver user specified
1197 Added new fuctions silc_hash_table_find[_all]_ext to do
1198 extended lookup with specified hash and compare functions and
1199 specified user contexts.
1201 Added new function silc_hash_table_add_ext to add the key
1202 with specified hash function and user context.
1204 Added new function silc_hash_table_foreach to traverse all
1205 entrys in the hash table. Added SilcHashForeach callback
1208 Added new function silc_hash_table_del_by_context to delete
1209 the entry only if the context associated with the key matches.
1211 Affected files are lib/silcutil/silchashtable.[ch].
1213 * Removed silc_hash_[server/client/channel]_id and added just
1214 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1215 silc_hash_id_compare to compare two ID's using as the hash table
1216 comparison function. Added also silc_hash_data to hash
1217 binary data and silc_hash_data_compare to compare it.
1219 * Removed silc_idlist_find_client_by_hash as it is not needed
1220 anymore. Affected file silcd/idlist.[ch].
1222 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1223 to use internally the SilcHashTable. The new ID Cache is a lot
1224 faster than the old one. Some of the ID Cache interface was also
1225 rewritten and obsolete and stupid functions were removed.
1227 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Added entry_count field to the SilcHashTable to keep the number
1230 of the entries in the table. Implemented the function
1231 silc_hash_table_rehash. Added new function
1232 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1234 Fixed a minor bug in silc_hash_table_free.
1236 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1237 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1238 into the lib/silcutil/silcutil.[ch].
1240 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Implemented a collision resistant hash table into the
1243 lib/silcutil/silchashtable[ch]. See the header and the source
1244 for the SilcHashTable API.
1246 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Merged dotconf version 1.0.2 into lib/dotconf.
1250 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Do not compile anything in lib/silcsim/* if the SIM support
1253 is not enabled. The tree should now compile without problems
1256 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Compiled the SILC under cygwin. Compiled and tested briefly
1259 without problems. More tests needed. The SIMs didn't compile
1262 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1264 * Fixed possible crash in silc_get_username in the
1265 lib/silcutil/silcutil.c.
1267 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1269 * Fixed a va_arg in silc/client_ops.c.
1271 * Oops, RC5 routines were named AES and caused some problems
1272 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1274 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * Added new SilcIDIP structure into the lib/silccore/id.h and
1277 replaced the old `ip' fields from all SILC ID's to that type.
1278 This is a step towards IPv6 support.
1280 The silc_id_get_len takes now the ID as an extra argument.
1281 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1282 both IPv4 and IPv6 based ID's.
1284 The affected files are lib/silccore/id.[ch] and other files
1285 around the tree using these routines.
1287 * Removed the ID length arguments in server from various
1288 silc_server_send_notify_* routines -> they are not needed
1291 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1293 * Fixed memory leak in silc_encode_pem_file in the file
1294 lib/silcutil/silcutil.c.
1296 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Check minor version as well in the SKE. Affected files are
1299 silcd/protocol.c and lib/silcclient/protocol.c.
1301 * Added --identifier option to the server so that an identifier
1302 can be when creating the public key for the server. Affected
1303 file is silcd/silcd.c.
1305 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1306 lib/silccrypt/silcpkcs.c.
1308 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Register default ciphers and stuff when using -C option with
1311 the server. Affected file sildc/silcd.c.
1313 * Put back the servers public key filename format, it is better
1314 than the new one. For now, the client keys are saved with the
1315 new filename format. The affected file silc/client_ops.c.
1317 * Implemented the Cipher API for the rest of the ciphers that
1318 did not implement it or implemented it the wrong way.
1320 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Register default ciphers and stuff when using the -S option
1323 in the client. Affected file silc/silc.c. Same also when
1324 creating new key pair with -C option.
1326 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1328 * Fixed the silc_verify_public_key client operation function to
1329 save the public keys differently. The fingerprint is now
1330 used as filename and not the hostname. This way also the
1331 client keys are saved uniquely and not with hostnames. The
1332 affected file is silc/client_ops.c.
1334 * Trimmed the silc_hash_fingerprint function to remove extra
1335 whitespaces from the end of the fingerprint. The affected
1336 file is lib/silccrypt/silchash.c.
1340 * Added silc_cipher_register_default function to register all
1341 default ciphers. It can be used when configuration files
1342 does not exist and the application does not want any specific
1343 ciphers in any specific order.
1345 The SilcDList is now used as silc_cipher_list dynamically
1346 allocated cipher list. Removed the static list all together
1347 and now all ciphers must be allocated to the dynamic list.
1348 The silc_cipher_alloc routine was changed to check only the
1351 All silc_cipher_* routines that used to return int returns
1354 The affected files lib/silccrypt/silccrypt.[ch].
1356 * The same thing was done to silc_hash_* as for silc_cipher_*
1357 routines. Affected files lib/silccrypt/silchash.[ch].
1359 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1360 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1361 Added also silc_pkcs_[un]register[_default] functions.
1362 Removed the data_context from the PKCS API.
1364 * Added silc_hmac_register_default function to register default
1365 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1366 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1367 to unregister all hmacs at once.
1369 * Register the default ciphers, hash functions, PKCSs and HMACs
1370 if client's configuration file does not exist. The affected
1373 * The client did not load the hash functions from the SIM
1374 modules at all. Added support for this. Affected file is
1375 silc/clientconfig.c.
1377 * When decoding public key with silc_pkcs_public_key_decode, check
1378 the supported algorithm only if PKCS are registered. Affected
1379 file lib/silccrypt/silcpkcs.c. The same was done with the
1380 silc_pkcs_private_key_decode.
1382 * Fixed the SILC List routines to keep the list always in order.
1383 It used to change the list's order when traversing the list but
1384 not it preserves the order. Affected file lib/trq/silclist.h.
1386 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Added the client library to use the SilcSocketConnection's
1389 reference counter (by silc_socket_dup) to prevent the bug that
1390 the socket object may be freed underneath async operation.
1392 * The name resolv library checking fixes in the configure.in.pre.
1395 * Created new version of the protocol drafts for future
1396 development. The -03 drafts are the ones that will be changed
1397 in the trunk now and the -02 will remain as they are.
1399 * Send list of CUMODE notifys to the router when announcing
1400 the channel users to the router. Affected file silcd/server.c.
1401 If the router receiving channel founder CUMODE for a channel
1402 that already has channel founder it will send CUMODE notify
1403 to the sender to remove the channel founder rights from the
1404 announced client. Affected file silcd/packet_receive.c.
1406 * The CUMODE notify may now use Server ID as well as the entity
1407 who changes the mode. Updated protocool specs.
1409 * Updated INSTALL and README files.
1411 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * New web pages in the http://silc.pspt.fi. The pages was
1418 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1420 * Implemented the [DenyConnectin] config section in the server.
1421 Added silc_server_config_denied_conn to check whether incoming
1422 connection is denied. Affected file silcd/serverconfig.[ch].
1424 * Do not check the ports when checking the incoming configuration
1425 data if the port is 0, meaning any. Affected file is
1426 silcd/serverconfig.c.
1428 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Fixed buffer overflow in silc_string_compare in the file
1431 lib/silcutil/silcutil.c.
1433 * Fixed double free in silc_server_command_leave in the file
1436 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Fixed the version checking in the server. Affected file is
1441 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Fixed the configuration data fetching when accepting new
1444 connections in the server. Affected file silcd/server.c.
1446 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Added `sender_entry' argument to the function
1449 silc_server_packet_relay_to_channel so that we can check
1450 whether some destination actually belongs to the same route
1451 the sender belongs (ie, we must not resend the packet to the
1452 sender). Affected file silcd/packet_send.[ch].
1454 * Added `servername' field to the SilcClientEntry in the server
1455 to hold the name of the server where client is from. Affected
1456 file is silcd/idlist.h.
1458 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Moved the channel message encrypting in the router betwen
1461 router connections from silc_server_channel_message to the
1462 silc_server_packet_relay_to_channel since we want to check
1463 whether we have anybody channel before encrypting anything.
1464 Affected files silcd/packet_[receive/send].c.
1466 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Fixed the [AdminConnection] server config section to support
1469 multiple entries. Affected file silcd/serverconfig.c.
1471 * Added support into the server to check the validity of the
1472 incoming connection before executing any KE or authentication
1475 * The connection configuration is now saved to the KE and
1476 connection auth protocol contexts and not fetched anymore in
1477 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1479 * The local hosts listenning address and port is also resolved
1480 now when starting the server. We want to have the socket object
1481 to include the real address and port for the listener. Added
1482 new function silc_net_check_local_by_sock into the files
1483 lib/silcutil/silcnet.[ch].
1485 * Fixed a broadcast bug in server -> do not broadcast if we
1488 * Fixed a routing bug. Do not route broadcast packets ever.
1489 Broadcast packets must be processed always and not routed since
1490 they may be destined to some other host than yourself and thus
1491 would get routed without no good reason. Affected file is
1494 * Added function silc_server_config_is_primary_route to check
1495 whether primary router connection has been configured (a router
1496 configuration that we are initiating). If there is not, we
1497 will assume that there is only two routers in the SILC network
1498 and we will use the incoming router connection as our primary
1499 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1501 * Changed the order of the broadcasting. Broadcast _after_ the
1502 packet has been processed not before. Affected file is
1505 * Fixed a [ClientConnection] parsing bug. The port was never
1506 parsed correctly thus resulting to port 0. Affected file
1507 silcd/serverconfig.c.
1509 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1510 argument and did not set the broadcast packet flag. Affected
1511 file silcd/packet_send.c. Fixed same bug in the function
1512 silc_server_send_notify as well.
1514 * If we receive NEW_ID packet for our own ID in the server, ignore
1517 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Removed the nickname from the Private Message Payload.
1522 Updated the code and the protocol specs.
1524 * Updated protocol specs for submitting to the IETF.
1526 * Tweaked the Random Number Generator a bit. Affected file
1527 lib/silccrypt/silcrng.c. Exported a new function
1528 silc_rng_[global]_add_noise which can be used to add more
1531 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Do not parse packets with different timeout when protocol
1534 is active -> may cause problem with rekey. Affected file
1537 * When server receives signoff notify it must not create
1538 new channel key if the client is on any channels since the
1539 sender of the signoff notify will create it.
1541 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Added printing of error messages during SKE protocol from the
1544 failure packet sent by server during SKE. Affected file
1547 * Removed the client's failure_callback handling with timeout
1548 and handle it immediately when received.
1550 * The SKE library returned wrong type in SUCCESS and FAILURE
1551 packets. They must be 32 bit MSB not 16 bit MSB.
1553 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Ok, rewrote the logic of the re-key and now it seems to work.
1556 I tested it on high traffic with frequent re-keys without
1557 problems. Added hmac_receive (and renamed hmac to hmac_send)
1558 in SilcClientConnection in lib/silcclient/client.h and
1559 in SilcIDListData in silcd/idlist.h. Also, removed the
1560 SilcPacketParserContext's cipher and hmac fields as they are
1561 not needed anymore and actually caused some problems when
1562 the ciphers and hmac's changed underneath the packet parser.
1564 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * If re-key protocol is active then process the incoming packets
1567 synchronously since we must assure that icoming packets encrypted
1568 with the old key is processed before the new keys is set to
1569 use. This is true other packets than for REKEY packets.
1570 Affected file silcd/server.c. The same was done to client library
1571 as well, affected file lib/silcclient/client.c.
1573 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1575 * Fixed bug in client and server to accept the force send if
1576 the packet is send from silc_[server/client]_packet_process
1577 function. Otherwise the packets are never delivered, oops.
1579 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Disable force sending of packets when REKEY protocol is active.
1582 We must assure that no packet is sent directly when rekey is
1583 performed. All packets must be sent through packet queue.
1584 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1585 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1586 function is silc_[server/client]_packet_send_real to check
1589 * Replaced the SIM paths from example config files to
1590 /usr/local/modules. Also, make install creates now
1591 /usr/local/silc/logs directory to hold all the SILC server
1594 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1596 * Made the configure.in.pre work on Solaris. Patch by salo.
1598 * Made all ciphers compatible with non-x86 machines. Defined
1599 CBC mode macros into lib/silccrypt/ciphers_def.h.
1601 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Fixed the make install.
1605 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1607 * When MAC computation fails the silc_packet_decrypt returned 0
1608 even though it was supposed to return -1. Fixed this. The
1609 affected file is lib/silccore/silcpacket.c.
1611 * Do not replace the config files in /etc/silc (in make install)
1612 if they already exist. Affected file ./Makefile.am.
1614 * Do not send re-key packets immediately but through packet queue.
1615 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1617 * Changed silc_net_check_host_by_sock to return FALSE if the
1618 IP/DNS could not be resolved. Though, it returns the IP address
1619 now even if it could not resolve it (but returns also FALSE).
1620 Affected file lib/silcutil/silcnet.[ch].
1622 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Added silc_pkcs_decode_identifier to decode the public key's
1625 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1626 Added also silc_pkcs_free_identifier. Added also new context
1627 SilcPublicKeyIdentifier.
1629 * Added -S option to the silc client. It is used to dump the
1630 contents of the specified public key file.
1632 * Changed the PKCS api to return the public key length when
1633 setting the public key.
1635 * Fixed a fatal bug in the public and private key file loading.
1636 Affected file lib/silccrypt/silcpkcs.c.
1638 * Execute the packet parsing for client with zero (0) timeout
1639 if the protocol is active. Affected file silcd/server.c.
1641 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1643 * Made the key generation options to the silcd program. Added
1644 -C option, equivalent to client's option.
1646 * Added new [ServerKeys] config section to the server. It
1647 configures the server's public and private key.
1649 * Defined generic Public Key Payload into the protocol
1650 specification to send specific type of public keys and
1653 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1654 public key or certificate.
1656 * Implemented the GETKEY command to the server and to the
1657 client library and on user interface.
1659 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1663 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Added SilcServerRekey context into silcd/idlist.h.
1667 * Added the PFS support as defined in the specification to the
1668 SKE protocol. Affected files lib/silcske/*.c.
1670 * Added `ske_group' field to the SilcServerRekey context to hold
1671 the number of the SKE group that is used with PFS in re-key.
1672 Affected file silcd/idlist.h.
1674 * Added PFS re-key support to the server. Affected file is
1677 * Added silc_protocol_cancel to cancel execution of the next
1678 state of the protocol. Affected file is
1679 lib/silccore/silcprotocol.[ch].
1681 * Added the re-key support with and without PFS to the client
1682 library. Re-key is performed once in an hour, by default.
1684 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1685 Added silc_client_rekey_callback and silc_client_rekey_final.
1686 Affected files are lib/silcclient/protocol.[ch] and
1687 lib/silcclient/client.[ch].
1689 * Removed the `hmac_key' and `hmac_key_len' fields from the
1690 SilcClientConnection structure; not needed. Affected file is
1691 lib/silcclient/client.h.
1695 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Do not ask whether user wants to use the negotiated private key
1698 for private messages, just use it. Affected file is
1699 silc/local_command.c.
1701 * Added `send_enc_key' and `enc_key_len' fields to the
1702 SilcIDListData structure since they are needed in the re-key
1703 phase. Affected file is silcd/idlist.[ch].
1705 * Implemented the simple re-key protocol into the server.
1706 Affected files silcd/server.c and silcd/protocol.[ch]. The
1707 re-key will be performed once in an hour, by default.
1709 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1710 Added silc_server_rekey, silc_server_rekey_callback and
1711 silc_server_rekey_final.
1713 * Removed Tunneled flag from the protocol. Updated the code
1714 and the specifications.
1716 * Adde `pfs' field to the SilcIDListData to indicate whether
1717 the PFS is to be performed in the re-key. Affected file is
1720 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1723 int64 of at least the xintXX size. If void * is less that 4
1724 bytes uint32 * will be used. Defined bool as boolean.
1726 * Changed _ALL_ unsigned long and unsigned int to uint32,
1727 unsgined short to uint16 in the source tree.
1729 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1730 not handle clients that has entry->data.registered == FALSE.
1731 They are not in the network anymore. Affected file is
1734 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Implemented the sending of the SERVER_SIGNOFF notify in the
1737 server. Affected file is silcd/server.c.
1739 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1740 Added also silc_notify_payload_encode_args into the
1741 lib/silccore/silcnotify.[ch].
1743 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1744 Affected file silcd/packet_receive.c.
1746 * Implemented the SERVER_SIGNOFF notify handling in the client
1747 library. Affected file lib/silcclient/client_notify.c. Also,
1748 implemnted the printing of the SERVER_SIGNOFF info to the
1749 application. Affected file silc/client_ops.c.
1751 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1752 if the deleting was successful. Affected file silcd/idlist.[ch].
1754 * Added support for public key authentication in the connection
1755 authentication protocol in the client library. Affected file
1756 lib/silcclient/protocol.c.
1758 * Changed the server's silc_idlist_get_clients_by_* interface
1759 to support already allocated array so that new entries may be
1760 added to pre-allocated array. Affected file silcd/idlist.[ch].
1761 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1762 and command replies.
1764 * All command reply functions in the server now calls the
1765 pending command callback even if error occured. This way the
1766 error will be delivered to the client as well. Affected files
1767 silcd/command.c and silcd/command_reply.c.
1769 * Fixed INFO command to return local server's info if no server
1770 was provided. Affected file lib/silcclient/command.c.
1772 * Removed RESTART command for good. Updated the code and the
1775 * Rewrote parts of the task system. It is a bit simpler now.
1776 Removed unsued task priorities. The affected files are
1777 lib/silcutil/silctask.[ch].
1779 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Moved the USERS printing from the library to the application.
1782 Affected files lib/silcclient/command.c and silc/client_ops.c.
1784 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Added channel key re-key support. The re-key is perfomed
1789 only by the router and is done once in an hour. Added `rekey'
1790 field to the SilcChannelEntry in the server. Affected files
1791 silcd/server.c and silcd/idlist.h.
1793 * Added silc_task_unregister_by_context into the file
1794 lib/silcutil/silctask.[ch].
1796 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Added SILC_UMODE_GONE mode to indicate when the client is not
1799 present in the SILC network. Added also support to the local
1800 command AWAY that will set this mode. Added support of showing
1801 "xxx is gone" in WHOIS command. The USERS command shows the
1802 gone status as well.
1804 * Fixed setting server and router operator privileges in the
1805 server's UMODE command. Affected file silcd/command.c.
1807 * Merged the SKE KE1 and KE2 payloads into one payload. The
1808 new KE payload is equivalent to the old KE2 payload.
1810 Cleaned up the SKE Start Payload parsing. It now uses the
1811 simple buffer unformatting to do the parsing. A lot faster
1814 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1815 to the SKE that is used to indicate whether both of the SKE
1816 parties should perform authentication. By default only the
1817 responder performs authentication. By setting this flag also
1818 the initiator must do authentication. By default it is unset
1819 since in normal SKE case, client to server connection, only
1820 the responder should do authentication. When doing SKE between
1821 two clients both should perform authentication. Updated the
1822 code and the protocol specs.
1824 * A little fix to IDENTIFY command in the server. Search the
1825 client first by hash not nickname. Affected file is
1828 * Fixed the silc_client_close_connection to support closing
1829 the client to client connections wihtout deleting too much
1830 data. Affected file lib/silcclient/client.c.
1832 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1833 are received if protocol used to be active but is not anymore
1834 the application would crash due to NULL pointer dereference.
1835 Affected files silcd/server.c and lib/silcclient/client.c.
1837 * Added `hash' field to the SilcClientConnection to include
1838 the hash function negotiated in the SKE protocol.
1840 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1841 to set the channel founder authentication data. A client can
1842 claim the founder rights later by providing the authentication
1843 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1844 This way the channel founder can regain the channel founder
1845 privileges even it is left the channel. This works only on
1846 local server and the client must be connected to the same
1847 server to be able to regain the founder rights. Updated the
1848 protocol specs accordingly.
1850 Added support to the CMODE command in the client to set the
1851 founder auth data. Read the README to see how to set it.
1853 Added support to the CUMODE command to claim the founder
1854 rights. Read the README to see how to do it.
1856 Added support for the founder authentication to the Channel
1857 Entry in the server. Affected file silcd/idlist.h.
1859 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1860 server's CMODE command. Affected file silcd/command.c.
1862 * Added the following new functions into lib/silccore/silcauth.[ch]:
1863 silc_auth_get_method and silc_auth_get_data.
1865 * The server now saves the remote hosts public key to the
1866 SilcIDListData pointer. Affected file silcd/protocol.c.
1868 * The normal server now does not remove the channel entry from
1869 the cache if the founder authentication data is set. It used
1870 to remove it if the founder was the last one on the channel on
1871 the server and left the channel. The auth data is saved and
1872 if the channel is re-joined later the old entry is used with
1873 the old auth data. Affected files silcd/command_reply.c and
1876 * Removed the `pkcs' field from the SilcIDListData structure
1877 in the server; it is not used. Affected file silcd/idlist.h.
1879 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1881 * Fixed packet processing on slow links. Partial packets were
1882 never re-processed because the incoming data buffer was cleared
1883 by the application. Application must not directly clear the
1884 sock->inbuf, the packet processing routines handle it. Fixed
1885 this in client library and in server.
1887 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Fixed the WHOIS and IDENTIFY send reply function to really
1890 check whether to send list or just one entry. Affected file
1893 * Cleaned up the LEAVE command's channel key distribution. The
1894 affected file silcd/command.c.
1896 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1897 can enforce the channel mode as well. In that case the ID
1898 includes the ID of the server. The code now enforces the
1899 mode change if the router have different mode than the server.
1901 * The notify client operation with CMODE_CHANGE notify can now
1902 return NULL client_entry pointer if the CMODE was not changed
1903 by client. Application must check for this.
1905 * Added <Server ID> argument to INFO command to support server
1906 info fetching by Server ID.
1908 * Added silc_server_announce_get_channel_users to get assembled
1909 packets of channel users of the specified channel. Affected
1910 file silcd/server.[ch].
1912 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1913 was freed underneath the ID Cache.
1915 * Re-announce clients when the server received CHANNEL_CHANGE
1916 notify from the router. Affected file silcd/packet_send.c.
1918 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1921 crashed since it did not handle the fact that there is no cipher
1922 called "3" and didn't check the error condition. Now fixed.
1924 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1925 flag. It can be used to send message requests.
1927 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Implemented the RESTART command in the client.
1931 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1932 notice type messages. Added notice printing to the user
1935 * The channel keys are not re-generated if the channel's mode
1936 is PRIVKEY, ie private key on the channel exists. Affected
1937 files silcd/server.c and silcd/command.c.
1939 * Fixed a little bug in channel message delivery when channel
1940 private keys are set in the server. Affected file is
1941 silcd/packet_send.c.
1943 * Changed the setting on channel->on_channel = TRUE from the
1944 silc_client_save_channel_key to the JOIN command reply. The
1945 key payload is not received if the private channel key is set.
1946 Affected file lib/silcclient/command_reply.c and the
1947 lib/silcclient/client_channel.c.
1949 * When the CMODE_CHANGE notify is sent and the channel private
1950 key mode is removed the channel key must be re-generated in
1951 other cells as well. Added this support for the router in the
1952 silcd/packet_receive.c.
1954 * Added new local command NOTICE to send notice message on
1955 channel. Affected file silc/local_command.[ch].
1957 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Added new local command ME to the client. It is used to send
1960 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1961 some action. Affected file silc/local_command.[ch].
1963 * Changed channel_message and private_message client operations
1964 to deliver the message flags to the application. Added also
1965 the `flags' arguments to the silc_client_send_channel_message
1966 and silc_client_send_private_message functions. Affected file
1969 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Redefined the Private Message Payload to support private message
1972 keys and to support the new private message flags. Updated
1973 the protocol specs. Flags makes it possible to have for example
1974 CTCP style messages.
1976 * Added new type SilcPrivateMessagePayload and defined an API
1977 for it in the lib/silcclient/silcprivate.[ch].
1979 * Tested private message private keys successfully. Tested the
1980 private message key set, unset and list commands with the new
1983 * Redefined the Channel Message Payload to include the channel
1984 message flags (equal with private message flags) to support
1985 for example CTCP style messages.
1987 * Defined some of the message (for channel and private message)
1988 flags. Updated the protocol specs and added the flags to the
1989 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1991 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Added SilcKeyAgreementStatus type to the key agreement routines
1994 to indicate the current status and error if one occured.
1995 The status types are defined in the lib/silcclient/silcapi.h.
1997 * Added new local command KEY that is used to set and unset private
1998 keys for channels, set and unset private keys for private messages
1999 with remote clients and to send key agreement requests and
2000 negotiate the key agreement protocol with remote client. The
2001 key agreement is supported only to negotiate private message keys,
2002 it currently cannot be used to negotiate private keys for channels,
2003 as it is not convenient for that purpose.
2005 * Fixed a minor pending callback setting bug in the function
2006 silc_client_get_client_by_id_resolve, now the function works.
2007 Affected file lib/silcclient/idlist.c.
2009 * Added function silc_net_get_local_port to get local bound
2010 port by socket. Added to lib/silcutil/silcnet.[ch].
2012 * Added `sockets' and `sockets_count' fields to the SilcClient
2013 object. They hold the sockets of the listenning sockets in
2014 the client. Listenning sockets may be for example the key
2015 agreement server. Affected file lib/silcclient/client.[ch].
2016 Added functions the silc_client_add_socket and the
2017 silc_client_del_socket. They are exported to the application
2020 * Added ~./silc/clientkeys to support other client's public keys.
2022 * Renamed verify_server_key client operation to verify_public_key
2023 and added one argument to indicate the type of the connection
2024 (server, client etc.).
2026 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * Added silc_server_connection_auth_request to handle the
2029 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2030 silcd/packet_receive.[ch].
2032 * Added silc_server_send_connection_auth_request into the
2033 silcd/packet_send.c to send the connection auth request packet.
2035 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2038 * Fixed the public key authentication in responder side in the
2039 server. The `auth_data' pointer includes the SilcPublicKey
2040 not the path to the public key. Affected file silcd/protocol.c.
2042 * Implemented the public key authentication in the initiator side
2043 in the server. Affected file silcd/protocol.c.
2045 * Removed the [RedirectClient] config section from the server
2046 configuration. Is not needed and I don't want to implement it.
2048 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Cleaned up the CMODE command in the server. It now works
2051 correctly and supports all the modes defined in the protocol.
2052 Affected file is silcd/command.c.
2054 * Added `hmac_name' field to the SilcChannelEntry in the server
2055 to hold the default HMAC of the channel. It can be set when
2056 creating the channel (with JOIN command). Affected files
2059 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2060 type to indicate the change of the current cipher and hmac
2061 on the channel. Client can safely ignore the <cipher> argument
2062 (if it chooses to do so) since the CHANNEL_KEY packet will
2063 force the channel key change anyway. The <hmac> argument is
2064 important since the client is responsible of setting the new
2065 HMAC and the hmac key into use.
2067 * Fixed the CMODE command in the client library as well.
2069 * Tested CMODE command in router environment successfully.
2071 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Show the version of the remote client (or server) when connecting
2074 to the server. It is logged to the log file. Affected file
2075 is silcd/protocol.c.
2077 * Fixed the KILLED notify handling in the client library. The
2078 client must be removed from all channels when receiving the
2081 Also, do not remove the client entry when giving the KILL
2082 command but when the KILLED notify is received.
2084 * Removed silc_idlist_find_client_by_nickname from the server.
2085 Not needed anymore. Affected files silcd/idlist.[ch].
2087 * Implemented the CHANNEL_CHANGE notify type handling to the
2088 server. Affected file silcd/server.c.
2092 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2094 * Added silc_server_send_notify_invite to send the INVITE
2095 notify between routers.
2097 * Implemented the INVITE command correctly to the server.
2099 * Implemented the INVITE notify type handling in the server.
2101 * Implemented the INVITE command to the client library and on the
2104 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Added function silc_server_get_client_resolve to find the
2107 client entry by ID from all ID lists and then resolve it
2108 (using WHOIS) if it cannot be found. Affected file is
2111 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Implemented the BAN command to the client library.
2115 * The JOIN command in the server now checks the invite list
2118 * Changed the silc_command_reply_payload_encode_va and the
2119 silc_command_payload_encode_va to support that if argument is
2120 NULL it ignores and checks the next argument. Affected file
2121 lib/silccore/silccommand.c.
2123 * Added silc_server_send_notify_ban to send the BAN notify
2124 type between routers.
2126 * Chaned the silc_notify_payload_encode to support that if
2127 argument is NULL it ignores and checks the next argument.
2128 Affected file lib/silccore/silcnotify.c.
2130 * Tested ban lists in router environment successfully.
2132 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Implemented BAN command to the server, in silcd/command.[ch].
2136 * Removed the BAN and INVITE_LIST modes from the CMODE command
2139 * Added function silc_string_match to regex match two strings.
2140 Affected files lib/silcutil/silcutil.[ch].
2142 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Redefined parts of the SilcChannelEntry in the server to support
2145 the new ban and invite lists.
2147 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Redefined the INVITE command. The same command can be used to
2150 invite individuals to the channel but also to manage the invite
2151 list of the channel (to add to and remove from the invite list).
2152 Updated the protocol specs.
2154 * Added new command SILC_COMMAND_BAN that can be used to manage
2155 the ban list of the channel. Updated the protocol specs.
2157 * Removed the channel modes: the SILC_CMODE_BAN and the
2158 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2159 in the CMODE command. The equivalent features are now available
2160 using INVITE and BAN commands. Updated the protocol specs.
2162 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2163 in the network about change in the current ban list. The notify
2164 type is not used by the client.
2166 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2167 support the invite lists.
2169 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Added new function silc_string_regexify that converts string
2172 including wildcard characters into regex string that can
2173 be used by the GNU regex library. Added into the file
2174 lib/silcutil/silcutil.[ch].
2176 Added silc_string_regex_combine to combine to regex strings
2177 into one so that they can be used as one regex string by
2178 the GNU regex library. Added into the file
2179 lib/silcutil/silcutil.[ch].
2181 Added silc_string_regex_match to match two strings. It returns
2182 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2184 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Imported GNU regex to the soruce tree into lib/contrib.
2187 Fixed some compiler warning from the regex.c.
2189 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Fixed MOTD command in the server to work in router environment.
2193 * Fixed the MOTD command in the client library to support
2194 the server argument in the command.
2196 * Added `nickname_len' argument to the silc_idlist_add_client
2197 in the server, as the `nickname' argument may be binary data
2200 * Added silc_idlist_get_channels to return all channels from
2203 * Implemented LIST command to the server. Affected file is
2206 * Implemented the LIST command to the client library and on the
2209 * Added [<user count>] argument to the LIST command reply.
2210 With private channels the user count is not shown.
2212 * Updated TODO and README.
2214 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2216 * The client entry's data.registered must be TRUE even with
2217 global client entry on global client list. The data.registered
2218 is used to check whether the client is anymore in the network,
2219 for example with WHOWAS command so it must be valid.
2221 * Fixed the WHOWAS command in the server. It now actually works
2222 in router environment. Added function into silcd/command_reply.c
2223 silc_server_command_reply_whowas_save.
2225 * Added silc_idlist_purge function to the silcd/idlist.c
2226 to periodically purge the ID Cache.
2228 * Fixed INFO command in the server. It works now in router
2229 environment. Added <server name> argument to the INFO command
2230 reply. Updated the protocol specs.
2232 * Fixed minor bug in silc_idcache_purge to not purge if the
2233 expire value is zero.
2235 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2236 they were buggy because of the WHOWAS information.
2238 * Fixed local command MSG to handle the async resolving of
2239 the remote client properly. It used to fail the first MSG.
2240 Affected file silc/local_command.c.
2242 * Added `data_len' field to SilcIDCache context.
2244 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Update TODO. Todo in commands in the server.
2248 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2251 used by routers as broadcast packet to inform other routers
2252 about the changed user mode.
2254 Implemented the notify handling in the server. Affected file is
2255 silcd/packet_receive.c. Added the function
2256 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2258 * Added new generic Channel Payload and deprecated the New Channel
2259 Payload. The New Channel Payload is now the generic Channel
2262 * Added new argument `mode' to the silc_server_send_new_channel
2263 as it is required in the Channel Payload now.
2265 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2266 and created a new and real SilChannelPayload to represent the
2267 new generic Channel Payload. Implemented the encode/decode
2268 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2270 * Added silc_server_get_client_channel_list to return the list
2271 of channels the client has joined for WHOIS command reply.
2272 Affected file silcd/server.[ch].
2274 * Implemented the channel list sending in the WHOIS command reply
2275 in server and in the client.
2277 Implemented the channel list displaying on the user interface
2278 as well. Affected file silc/client_ops.c.
2280 * Added silc_channel_payload_parse_list to parse list of Channel
2281 Payloads. It returns SilcDList list of SilcChannelPayloads.
2282 Client for example can use this function to parse the list of
2283 channels it receives in the WHOIS command reply. The caller
2284 must free the list by calling silc_channel_payload_list_free.
2285 Affected files lib/silccore/silcchannel.[ch].
2287 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Added one new argument <user mode> to the WHOIS command reply
2290 to return the mode of the user in SILC. Updated the protocol
2293 Implemented it to the server and client.
2295 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Fixed the mode printing on the user interface on joining.
2298 Affected file silc/client_ops.c.
2300 * Implemented the UMODE command and user modes in general to the
2301 client library and to the user interface.
2303 * Implemented the UMODE command to the server.
2305 * The server now sends UNKNOWN_COMMAND error status if client sends
2306 unknown command. Affected file silcd/command.c.
2308 * All server commands now handle the command identifier the right
2309 way when sending the command reply to the client. The client can
2310 use to identify the command replies with the identifier.
2312 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Added silc_server_get_client_route to resolve the route to
2315 the client indicated by the client ID. Affected file is
2318 * Added silc_server_relay_packet as general function to relay
2319 packet to arbitrary destination. This deprecates functions
2320 like _send_private_message_key, _relay_notify etc. Affected
2321 file is silcd/packet_send.[ch].
2323 Removed silc_server_send_key_agreement,
2324 silc_server_send_private_message_key and
2325 silc_server_packet_relay_notify functions from the file
2326 silcd/packet_send.[ch].
2330 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2331 server. Affected file silcd/packet_receive.[ch].
2333 * Implemented the KILL command to the client. Implemented the
2334 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2335 Affected files lib/silcclient/command[_reply].c and
2336 lib/silcclient/client_notify.c. Implemented the KILL notify
2337 printing in the user inteface.
2339 * Fixed a lot silc_parse_nick memory leaks from the client
2340 library in the file lib/silcclient/command.c.
2342 * Changed the silc_server_send_notify_on_channels's `sender'
2343 argument from SilcSocketConnection to SilcClientEntry to
2344 check the sender as entry and not as connection object and not
2345 to send to the client provided as argument. The affected file
2346 is silcd/packet_send.[ch].
2348 * The notify packets that are destined directly to the client used
2349 to not to be processed by the server. Now changed that and the
2350 server processes all notify packets. After relaying the packet
2351 to the client the notify packet is processed in the server.
2353 * The silc_server_free_client_data now checks whether there is
2354 pending outgoing traffic for the client and purges the data to
2355 the network before removing the client entry.
2357 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2360 an client is killed from the SILC Network. Updated the protocol
2363 Added new function silc_server_send_notify_killed to the
2364 silcd/packet_send.[ch].
2366 * Added function silc_server_packet_relay_notify to relay notify
2367 packets that are destined directly to a client. In this case
2368 the server does not process the notify packets but merely relays
2369 it to the client. Affected file silcd/packet_send.[ch].
2371 Added also silc_server_packet_process_relay_notify to check
2372 whereto relay the notify. Affected file is
2373 silcd/packet_receive.[ch].
2375 * Implemented the KILL command to the server.
2379 * Added the backup schema desgined last fall to the protocol
2380 specs for everyone to see. The specification is in the
2381 *-spec-xx.txt draft and the packet type definitions for the
2382 backup routers is in *-pp-xx.txt draft. Thusly, added also
2383 new packet type SILC_PACKET_CELL_ROUTERS.
2385 * A big security problem in the implementation discovered. The
2386 signoff of an client did not cause new channel key generation
2387 which it of course should've done. The channel keys must be
2388 always re-generated when client leaves (or signoffs) the channel.
2389 The silc_server_remove_from_channels funtion now handles
2390 the channel key re-generation.
2392 * Added `sender' argument to the silc_server_send_notify_on_channels
2393 to not to send the client provided as argument. Affected file
2394 silcd/packet_send.[ch].
2396 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Implemented OPER and SILCOPER commands into the server and
2401 * Added silc_auth_verify and silc_auth_verify_data to verify
2402 the authentication directly from the authentication payload.
2403 It supports verifying both passphrase and public key based
2404 authentication. Affected file lib/silccore/silcauth.[ch].
2406 * Added `hash' field to the SilcIDListData structure. It is the
2407 hash negotiated in the SKE protocol. Affected file is
2410 * Slight redesigning of the SilcAuthPayload handling routines.
2411 Do not send SilcPKCS but SilcPublicKey as argument.
2413 * Implemented the public key authentication support to the
2414 serverconfig. The public key is loaded from the provided path
2415 and saved as authentication data to void * pointer. Thus,
2416 changed the unsigned char *auth_data to void *auth_data;
2418 * Fixed SHUTDOWN command to send the reply before the server
2419 is shutdown. :) Affected file silcd/command.c.
2421 * Fixed fatal bug in CONNECT command. The hostname was invalid
2422 memory and server crashed. Affected file silcd/command.c.
2424 * Fixed fatal bug in CLOSE command. The server_entry became
2425 invalid but was referenced later in the command. Affected file
2428 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Fixed fatal bug in failure packet handling. Server ignored
2431 the failure and thus crashed when it came.
2435 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2438 that the command may be executed only once in (about) 2 seconds.
2439 The old SILC_CF_LAG flag is same but allows command bursts up
2440 to five before limiting.
2442 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2443 server code. Various commands now includes the CF_LAG_STRICT
2444 flag to disallow any kind of miss-use of the command.
2446 * Fixed the silc_buffer_unformat to not to allocate any data
2447 if the length of the data is zero. It used to allocate the
2448 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2450 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Changed the format of AdminConnection configuration section
2453 in the server. Added username of the admin to the format.
2454 Affected files silcd/serverconfig.[ch].
2456 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2457 to return admin configuration data by host, username and/or
2460 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Implemented WHOWAS command to the server. Added the functions:
2464 silc_server_command_whowas_parse,
2465 silc_server_command_whowas_send_reply,
2466 silc_server_command_whowas_from_client and
2467 silc_server_command_whowas_from_server
2469 * Added <Client ID> argument to the WHOWAS command reply. Updated
2470 the protocol specs accordingly.
2472 * Implemented WHOWAS command and command_reply to the client
2475 Implemented the WHOWAS printing on the user interface.
2477 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Added new argument to the WHOWAS command reply, the real name.
2480 It is an optional argument. Updated the protocol specs.
2482 * Added SilcIDCacheDestructor callback that is registered when
2483 the SilcIDCache is allocated. The callback is called when
2484 an cache entry in the ID Cache expires, or is purged from the
2485 cache. Added into lib/silccore/idcache.[ch].
2487 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2488 to destruct the client entries when the cache entry expires.
2489 Other ID Cache's in server and in the client library ignores
2492 * If the ID Cache entry's `expire' field is zero then the entry
2493 never expires. Added boolean `expire' argument to the
2494 silc_idcache_add function in the lib/silccore/idcache.[ch].
2495 If it is TRUE the default expiry value is used.
2497 * Added silc_server_free_client_data_timeout that is registered
2498 when client disconnects. By default for 5 minutes we preserve
2499 the client entry for history - for WHOWAS command.
2501 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Added support to the server to enforce that commands are not
2504 executed more than once in 2 seconds. If server receives
2505 commands from client more frequently, timeout is registered
2506 to process the commands. Affected file silcd/command.c.
2507 Added new function silc_server_command_process_timeout.
2509 * Changed NICK_NOTIFY handling in client library to check that
2510 if the client's nickname was changed, so there is no need to
2511 resolve anything from the server.
2513 * Removed error printing from the WHOIS and IDENTIFY commands.
2514 If error occurs then it is ignored silently in the client library.
2515 The application, however, may map the received error to
2516 human readable error string. The application currently maps
2517 the NO_SUCH_NICKNAME error to string.
2519 * Made the command status message public to the application. Moved
2520 them from lib/silcclient/command_reply.c to
2521 lib/silcclient/command_reply.h. The application can map the
2522 received command status to the string with the
2523 silc_client_command_status_message function.
2525 * Added check to the server to check that client's ID is same
2526 as the Source ID in the packet the client sent. They must
2529 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Added dist-bzip hook to the Makefile.am to make bzip2
2532 compressed distributions.
2534 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Server now enforces the maximum length for the nickname and
2537 the channel as protocol specification dictates. 128 bytes for
2538 nickname and 256 bytes for channel name.
2540 * Moved the WHOIS printing to the application. The client libary
2541 does not print out the WHOIS information anymore, the application
2542 must do it. Renamed silc_client_command_reply_whois_print to
2543 the silc_client_command_reply_whois_save.
2545 The client's idle time is also sent to the application now, and
2546 the idle is shown on screen.
2548 * Added silc_client_command_reply_identify_save to save the
2549 received IDENTIFY entries.
2551 * Do not check for channel private keys in message sending and
2552 reception if the channel does not have the PRIVKEY mode set.
2553 Affected file lib/silclient/client_channel.c.
2555 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2558 just surfaced after chaning the JOIN procedure.
2560 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Added silc_client_get_clients_by_list to get client entries
2563 from Client ID list, that is returned for example by JOIN
2564 and USERS command replies. The application should use this
2565 function for example when JOIN command reply is received to
2566 resolve the clients already on the channel (library does not
2567 do that anymore as USERS command reply is not used in the JOIN
2568 procedure anymore). Affected files lib/silcclient/silcapi.h and
2569 lib/silcclient/idlist.c.
2571 * JOIN command reply and USERS command reply returns now SilcBuffer
2572 pointers instead of unsigned char pointers when returning
2573 the client list and mode list.
2575 * Added <Client ID> argument to the JOIN command reply, mainly
2576 for the server to identify for which client the command was
2577 originally sent. Updated protocol specs accordingly.
2579 * Added SilcDlist private_key pointer to the SilcChannelEntry
2580 in the client to support the channel private keys. Affected
2581 file is lib/silcclient/idlist.h.
2583 * Added SilcChannelPrivateKey argument to the function
2584 silc_client_send_channel_message so that application can choose
2585 to use specific private ke if it wants to. If it is not provided,
2586 the normal channel key is used, unless private keys are set.
2587 In this case the first (key that was added first) is used
2588 as the encryption key.
2590 * Implemented the support for channel private key handling.
2591 Implemented the following functions:
2593 silc_client_add_channel_private_key,
2594 silc_client_del_channel_private_keys,
2595 silc_client_del_channel_private_key,
2596 silc_client_list_channel_private_keys and
2597 silc_client_free_channel_private_keys
2599 Affected file lib/silcclient/client_channel.c.
2601 * Added the support for the private keys in the channel message
2602 sending and encryption and in the message reception and
2603 decryption. Affected funtions are
2604 silc_client_send_channel_message and silc_client_channel_message.
2606 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Added SKE's key verify callback to the client library's
2609 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2611 * Removed the statement that server (or router) must send USERS
2612 command reply when joining to the channel so that the client
2613 knows who are on the channel. Instead, the client list and
2614 client's mode list is now sent in the JOIN command reply to the
2615 client who joined channel. This is better solution.
2617 * Added function silc_server_get_users_on_channel and function
2618 silc_server_save_users_on_channel to the silcd/server.[ch].
2620 * Removed function silc_server_command_send_users from the
2623 * Do not show topic on the client library anymore. The topic is
2624 sent in the command reply notify to the application and the
2625 application must show the topic now.
2627 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Added client searching by nickname hash into the IDENTIFY and
2630 WHOIS commands in the server as they were clearly missing from
2631 them. Affected file is silcd/command.c.
2633 * Fixed a bug in private message receiving in the client library.
2634 The remote ID was freed and it wasn't supposed, now it is
2637 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Minor fix to the channel payload; allocate the data area, as it
2640 needs to be of specific length.
2642 * If the key agreement port is zero then the operating
2643 system will define the bound port. Affected files are
2644 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2646 * Added new function silc_channel_payload_decrypt into the file
2647 lib/silccore/silcchannel.[ch].
2649 * Moved the channel message etc, check from silc_packet_decrypt
2650 to applications. The library calls now a generic
2651 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2652 when the packet is either normal or special. This was done to
2653 allow more wide range of checking that was not allowed when
2654 the code was in library. Now applications can do virtually any
2655 checks to the packet and return to the library the decision how
2656 the packet should be processed. Affected files are
2657 lib/silccore/silcpacket.[ch].
2659 Added silc_server_packet_decrypt_check to the server and
2660 silc_client_packet_decrypt_check to the client library.
2662 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2663 to send with specified source and destination information.
2665 * Channel message delivery between routers was broken after the
2666 channel key distribution was fixed earlier. The channel key
2667 was used be to distributed to other routers as well which is not
2668 allowed by the protocol. Now this is fixed and channel keys
2669 really are cell specific and the channel message delivery between
2670 routers comply with the protocol specification.
2672 * Fixed various commands in server to check also the global list
2673 for the channel entry and not just the local list. The affected
2674 file silcd/command.c.
2676 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Added assert()s to buffer formatting and unformatting routines
2679 to assert (if --enable-debug) when error occurs. Affected
2680 file: lib/silcutil/silcbuffmt.c.
2682 * Changed to auto-reconnect to check whether the remote host is
2683 router and register the re-connect timeout if it is. It used
2684 to check that whether we are normal server, but router must do
2685 auto-reconnect with another router as well. Affected file
2688 * Removed the [<key len>] option from CMODE command as the cipher
2689 name decides the key length, nowadays. See the defined ciphers
2690 from the protocol specification.
2692 * Added [<hmac>] option to the CMODE command to define the HMAC
2693 for the channel. Added SILC_CMODE_HMAC channel mode.
2695 * Added [<hmac>] option for the JOIN command so that user can
2696 select which HMAC is used to compute the MACs of the channel
2699 * Added Hmac field to the Channel Message Payload. The integrity
2700 of plaintext channel messages are now protected by computing
2701 MAC of the message and attaching the MAC to the payload. The
2702 MAC is encrypted. Now, it is clear that this causes some
2703 overhead to the size of the packet but rationale for this is that
2704 now the receiver can verify whether the channel message decrypted
2705 correctly and also when private keys are set for the channel the
2706 receiver can decrypt the packet with several keys and check from
2707 the MAC which key decrypted the message correctly.
2709 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2710 lib/silccrypt/silccipher.[ch].
2712 * Added silc_hash_len to return the digest length into the
2713 lib/silcrypt/silchash.[ch].
2715 * Rewrote parts of Silc Channel Payload interface in the
2716 lib/silccore/silcchannel.[ch]. The encode function now also
2717 encrypts the packet and parse function decrypts it.
2719 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Fixed a minor formatting bug in the SKE's key material processing.
2722 It actually might have processed the keys wrong way resulting
2725 * Redefined the mandatory HMAC algorithms and added new algorithms.
2726 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2727 and hmac-md5 truncated to 96 bits. The mandatory is now
2728 hmac-sha1-96. Rest are optional (including the one that used
2729 to be mandatory). Rationale for this is that the truncated HMAC
2730 length is sufficient from security point of view and can actually
2731 make the attack against the HMAC harder. Also, the truncated
2732 HMAC causes less overhead to the packets. See the RFC2104 for
2735 * Added new [hmac] configuration section. The SKE used to use
2736 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2737 is of course wrong. The official names that must be proposed in
2738 the SKE are the ones defined in the protocol specification
2739 (hmac-sha1-96 for example). The user can configure any hmac
2740 using any hash function configured in the [hash] section. At
2741 least, the mandatory must be configured.
2743 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2745 * Added HMAC list to the SKE proposal list. It has now both
2746 hash algorithm list and HMAC list. This makes the protocol
2747 incompatible with previous versions. The SKE now seems to work
2748 the way it is supposed to work, for the first time actually.
2750 * Defined plain Hash algorithms to the protocol specification.
2753 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * Implemented support for key agreement packets into the server.
2756 Added functions silc_server_key_agreement and
2757 silc_server_send_key_agreement. Other than these functions,
2758 server has nothing to do with this packet.
2760 * Added support for private message key packets into the server.
2761 Added functions silc_server_private_message_key and
2762 silc_server_send_private_message_key.
2766 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2767 called in the protocol's final callback instead in the END
2768 protocol state. This makes a little more sense and in the same
2769 time in client we can use the same protocol routines for normal
2770 key exchange and to key agreement packet handling as well.
2772 * Added to both client's and server's KE protocol context the
2773 SilcSKEKeyMaterial pointer to save the key material. We will
2774 bring the key material to the protocol's final callback by doing
2775 this. The final callback must free the key material.
2777 * Added SKE's packet_send callback into client's KE protocol
2778 context so that the caller can choose what packet sending function
2779 is used. This way we can use different packet sending when
2780 doing normal SKE when doing key agreement packet handling (in
2781 the key agreement packet handling we do not want to encrypt
2784 * Implemented the responder side of the key agreement routines
2785 in the client. The client can now bind to specified port and
2786 accept incoming key negotiation. The key material is passed
2787 to the application after the protocol is over.
2789 * Implemented the processing of incoming Key Agreement packet
2790 in the client. Added function silc_client_key_agreement to
2793 * Implemented the intiator side of the key agreement routines
2794 in the client. The client can now initiate key agreement with
2795 another remote client. The key material is passed to the
2796 application after the protocol is over.
2798 * Created client_keyagr.c to include all the key agreement
2801 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2802 SILC_TASK_CALLBACK except that it is not static.
2804 * Created client_notify.c and moved the Notify packet handling
2805 from the client.[ch] into that file.
2807 * Created client_prvmsg.c and moved all private message and
2808 private message key routines from the client.[ch] into that file.
2810 * Create client_channel.c and moved all channel message and
2811 channel private key routines from the client.[ch] into that file.
2813 * Changed silc_client_get_client_by_id_resolve to resolve with
2814 WHOIS command instead of IDENTIFY command, in the file
2815 lib/silclient/idlist.c.
2817 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Implemented the SKE's responder side to the Client library.
2821 * When FAILURE is received to the protocol do not trust it
2822 blindly. Register a timeout to wait whether the remote closes
2823 the connection as it should do it, only after that process the
2824 actual failure. This was changed to both client and server.
2826 * Added client_internal.h to include some of the structures
2827 there instead of client.h in lib/silcclient/.
2829 * Added function silc_task_unregister_by_callback to unregister
2830 timeouts by the callback function.
2832 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Some "Incomplete WHOIS info" errors has been appearing on the
2835 log files. Took away the entry->userinfo check from WHOIS
2836 reply sending. The entry->userinfo is now " " if client did not
2837 provide one. I thought this was fixed earlier but something
2838 is wrong still. Let's see if the error still appears.
2840 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Fixed a minor bug in the login when the channel key is
2843 re-generated in the server. It used to generate the key in
2844 wrong order and thus caused problems in the channel traffic.
2846 * Fixed a minor bug in channel key distsribution after
2847 KICK command. The key was not sent to the router even though
2850 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added silc_ske_process_key_material_data as generic routine
2853 to process any key material as the SILC protocol dictates. The
2854 function is used by the actual SKE library but can be used by
2855 applications as well. This relates to the private message keys
2856 and the channel private keys since they must be processed the
2857 same way the normal SILC session keys. The protocol dictates
2858 this. Affected files: lib/silcske/silcske.[ch].
2860 Added also silc_ske_free_key_material to free the
2861 SilcSKEKeyMaterial structure.
2863 * Defined silc_cipher_set_key function to set the key for
2864 cipher without using the object's method function. The affected
2865 files: lib/silccrypt/silccipher.[ch].
2867 * Implemented silc silc_client_add_private_message_key,
2868 silc_client_add_private_message_key_ske,
2869 silc_client_del_private_message_key,
2870 silc_client_list_private_message_keys and
2871 silc_client_free_private_message_keys functions in the
2874 Added functions silc_client_send_private_message_key to send
2875 the Private Message Key payload and silc_client_private_message_key
2876 to handle incoming Private Message Key payload.
2878 * Added Cipher field to the Private Message Key payload to set
2879 the cipher to be used. If ignored, the default cipher defined
2880 in the SILC protocol (aes-256-cbc) is used.
2882 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Removed lib/silcclient/ops.h file.
2886 Redefined parts of the SILC Client Library API. Created new
2887 file silcapi.h that deprecates the ops.h file and defines the
2888 published Client Library API. Defined also private message key
2889 API and channel private key API into the file.
2891 This is the file that the application must include from the
2892 SILC Client Library. Other files need not be included by
2893 the application anymore.
2895 * Added new key_agreement client operation callback and also
2896 defined the Key Agreement library API for the application.
2898 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2901 is used by clients to request key negotiation between another
2902 client in the SILC network. If the negotiation is started it
2903 is performed using the SKE protocol. The result of the
2904 negotiation, the secret key material, can be used for example
2905 as private message key.
2907 Implemented the Key Agreement payload into the files
2908 lib/silccore/silauth.[ch].
2910 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Redefined ciphers for the SILC protocol. Added some new ciphers
2913 and defined the key lengths for the algorithms. Changed the
2914 code accordingly. The default key length is now 256 bits.
2916 * Fixed SKE key distribution function silc_ske_process_key_material
2917 when the key length is more than 128 bits. The default key
2918 length in SILC is now 256 bits.
2920 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2921 to indicate unsupported algorithm.
2923 * Renamed rijndael.c to aes.c and all functions as well.
2925 * Fixed a long standing channel key setting bug in client library.
2926 Weird that it has never surfaced before.
2928 * Fixed bug in channel deletion. If the entire channel is removed
2929 then it must also delete the references of the channel entry
2930 from the client's channel list as the client's channel entry and
2931 the channel's client entry share same memory.
2933 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2935 * Implemented CONNECT and SHUTDOWN commands in the client.
2937 * Implemented CLOSE command to the client.
2939 * Added the function silc_idlist_find_server_by_name into the
2940 files silcd/idlist.[ch].
2942 Added the function silc_idlist_find_server_by_conn into the
2943 files silcd/idlist.[ch].
2945 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * DIE command was renamed to SHUTDOWN. Updated the both code
2950 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2951 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2953 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2956 * Added function silc_server_create_connection function to create
2957 connection to remote router. My server implementation actually
2958 does not allow router to connect to normal server (it expects
2959 that normal server always initiates the connection to the router)
2960 so the CONNECT command is only good for connecting to another
2963 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2966 or some other client was kicked from the channel.
2968 Implemented the handling of the notify type to both client
2971 Implemented silc_server_send_notify_kicked to send the KICKED
2972 notify. It is used to send it to the server's primary router.
2974 * Implemented the KICK command into server and client.
2976 * Added `query' argument to the silc_idlist_get_client function
2977 to indicate whether to query the client from server or not if
2980 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2981 to indicate that the client is not channel founder.
2985 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Removed the rng context from SilcPacketContext structure and
2988 changed that the packet routine uses the Global RNG API.
2990 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added support for quit message that client can "leave" on the
2993 channel when it quits the SILC. It is ditributed inside the
2994 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2996 Added silc_server_free_client_data that will take the
2997 signoff message as argument.
2999 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3001 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Updated parts of the protocol specification to keep it up
3006 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3009 payloads in one packet.
3011 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3012 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3013 use now the new List flag.
3015 * Also deprecated the following packet types: REPLACE_ID,
3016 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3018 * Added list support for Notify packet in server.
3020 * Added silc_server_send_notify_channel_change to send the
3021 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3022 the silc_server_send_replace_id.
3024 * Added silc_server_send_notify_nick_change to send the
3025 NICK_CHANGE notify type. Deprecates the function
3026 silc_server_send_replace_id.
3028 * Added silc_server_send_notify_join to send the JOIN notify type.
3029 Deprecates the function silc_server_send_new_channel_user.
3031 * Added silc_server_send_notify_leave to send LEAVE notify type.
3032 Deprecates the function silc_server_send_remove_channel_user.
3034 * Added silc_server_send_notify_cmode and
3035 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3036 types. Deprecates the silc_server_send_set_mode function.
3038 * Added SERVER_SIGNOFF notify type to indicate that server has
3039 quit. This means that all clients on the channel from that
3040 server will drop. This can be also used when netsplit happens.
3042 Deprecated REMOVE_ID packet type since it is not needed anymore
3045 Added silc_server_send_notify_server_signoff to send the
3046 SERVER_SIGNOFF notify type. Deprecates the function
3047 silc_server_send_remove_id.
3049 Added also silc_server_send_notify_signoff to send the
3050 SIGNOFF notify type.
3052 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3053 SILC protocol from this day on. Changed the protocol
3054 specification as well.
3056 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3057 notify type. It is used between routers to notify about
3058 topic changes on a channel.
3060 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3063 * Partly updated the protocol specification to comply with the
3064 changes now made. It is still though a bit outdated.
3066 * The JOIN notify type now takes one extra argument <Channel ID>.
3067 The packet used to be destined to the channel but now the
3068 JOIN type may be sent as list thus it is impossible to
3069 destine it to any specific channel. By adding this argument
3070 it is again possible.
3072 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Added CREDITS file. The CHANGES and CREDITS file will appear
3075 in the distribution as well.
3077 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3080 types in the server's silcd/packet_receive.c.
3082 * Implemented CMODE and CUMODE to work in router environment.
3084 * Fixed minor encoding and decoding buglet from the
3085 lib/silccore/silcmode.c.
3087 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3090 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3092 * Changed all SilcConfigServer* and silc_config_server* to
3093 SilcServerConfig* and silc_server_config*, respectively.
3096 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Associated the ID (client or server ID) to the Authentication
3099 Payload to avoid any possibility of forging. Updated the
3100 protocol specification and the code accordingly.
3102 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * The RSA key length is now save to the RsaKey context in the
3105 key generation process in lib/silccrypt/rsa.c. The key length
3106 is now used to figure out the maximum size of the block allowed
3107 to be encrypted/signed.
3109 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3110 is equivalent to the silc_mp_mp2bin but does not allocate any
3113 * Changed silc_mp_mp2bin API to take length argument. If it is
3114 non-zero then the buffer is allocated that large. If zero, then
3115 the size is approximated using silc_mp_sizeinbase, which however
3118 * Created Global RNG API which is global RNG that application can
3119 initialize. After initializing, any routine anywhere in the
3120 code (including library) can use RNG without allocating a new
3121 RNG object. This was done to allow this sort of use of the
3122 RNG in code that has no chance to allocate RNG object. All
3123 applications currently allocate this and many routines in the
3124 library use this. Affected file lib/silccrypt/silcrng.[ch].
3126 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3127 it to use the Global RNG API.
3129 * Defined Authentication Payload into protocol specification that
3130 is used during SILC session to authenticate entities. It is
3131 used for example by client to authenticate itself to the server
3132 to obtain server operator privileges.
3134 Implemented this payload into the lib/silccore/silcauth.[ch].
3135 Implemented also routines for public key based authentication
3136 as the new protocol specification dictates.
3138 Moved definitions of different authentication methods from
3139 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3141 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3142 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3143 silc_pkcs_verify_with_hash functions into the file
3144 lib/silccrypt/silcpkcs.[ch].
3146 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * The client entry's userinfo pointer must be always valid.
3149 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3150 will fail since it requires the userinfo. Now, the userinfo
3151 is allocated as "" if actual userinfo does not exist. Actually,
3152 it must exist and it is totally Ok to drop client connections
3153 that does not announce the userinfo. However, we will make
3154 this workaround for now.
3156 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3157 to return the remote port by socket.
3159 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3162 SILC_SERVER_PENDING_EXEC and added an new macro
3163 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3164 data or when error occurs while processing the pending command.
3166 Added new argument `destructor' into silc_server_command_pending
3167 and to the SilcServerCommandPending object. This destructor is
3168 now called after calling the pending callback or if error occurs
3169 immediately. If error occurs the actual pending callback won't
3170 be called at all - only the destructor. The destructor may be
3171 NULL if destructor is not needed.
3173 All this applies for client library code as well. Similar
3174 changes were made there as well for the pending commands.
3176 In the client, the application must now allocate the
3177 SilcClientCommandContext with the silc_client_command_alloc
3180 * Added reference counter to the SilcServerCommandContext. Added
3181 function silc_server_command_alloc and silc_server_command_dup
3184 Same type of functions added to the client library for the same
3187 * Removed the cmd_ident from IDListData away since it is now
3188 global for all connections. It is the command identifier used
3189 in command sending and with pending commands. The affected file
3192 * Added reference counter to the SilcSocketConnection objecet to
3193 indicate the usage count of the object. The object won't be
3194 freed untill the reference counter hits zero. Currently only
3195 server uses this, and client ignores it. The client must be
3196 set to use this too later. The affected files are
3197 lib/silccore/silcsockconn.[ch]. Added also the function
3198 silc_socket_dup to increase the reference counter.
3200 This was mainly added because it is possible that the socket
3201 is removed underneath of pending command or other async
3202 operation. Now it won't be free'd and proper DISCONNECTING
3203 flags, etc. can be set to avoid sending data to connection that
3204 is not valid anymore.
3206 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3207 the connection. After that it sets SILC_SET_DISCONNECTED.
3208 It is, however, possible that the socket data is not still freed.
3209 The silc_server_packet_process now checks that data is not
3210 read or written to connection that is DISCONNECTED. The socket
3211 get's freed when the reference counter hits zero.
3213 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Changed the client operation API: channel_message operation's
3216 `sender' is now the client entry of the sender, not the nickname
3217 and the `channel' is the channel entry, not the channel name.
3219 In the private_message operation the `sender' is now also the
3220 client entry of the sender not the nickname.
3222 Affected file is lib/silcclient/ops.h and all applications
3223 using the client operations.
3225 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Moved the calling of ops->connect() from connect_to_server_final
3228 into receive_new_id functin since that is the point when the
3229 client is actually allowed to send traffic to network. The
3230 affected file is lib/silcclient/client.c.
3232 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3235 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3236 (if needs broadcasting) instead of broadcasting the packets one
3237 by one which would make a burst in the network traffic.
3239 * Added `broadcast' argument to the functions in silcd/server.[ch]
3240 silc_server_create_new_channel[_with_id] to indicate whether
3241 to send New Channel packet to primary router.
3243 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Added new function into the silcd/server.[ch] files:
3246 silc_server_create_new_channel_with_id to create new channel with
3247 already existing Channel ID.
3249 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3250 lib/silccore/silcpacket.h. This packet is used t send list of
3251 Set Mode payloads inside one packet. Server uses this to set
3252 the modes for the channels and clients on those channels, that it
3253 announced to the router when it connected to it. The protocol
3254 specification has been updated accordingly.
3256 * The silc_server_new_channel did not handle the packet coming
3257 from normal server as it normally does not send that. However,
3258 when it announces its channels it does send it. Implemented
3259 the support for that.
3261 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3262 into the file lib/silccore/id.h.
3264 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Fixed memory leaks in the functions silc_idlist_del_client,
3267 silc_idlist_del_channel and silc_idlist_del_server in the file
3268 silcd/idlist.c. All of those leaked like a sieve.
3270 * Fixed some small memory leaks in the client's function
3271 silc_client_notify_by_server.
3273 * Added functions into silcd/server.c: silc_server_announce_clients,
3274 silc_server_announce_channels and silc_server_announce_server.
3275 These functions are used by normal and router server to announce
3276 to its primary router about clients, channels and servers (when
3277 router) that we own. This is done after we've connected to the
3280 These functions effectively implements the following packet types:
3281 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3282 and SILC_PACKET_NEW_ID_LIST.
3284 * Added new functions into the silcd/packet_receive.[ch]:
3285 silc_server_new_id_list, silc_server_new_channel_list and
3286 silc_server_new_channel_user_list to handle the incoming
3287 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3289 * Added support of changing Channel ID in the function
3290 silc_server_replace_id. If the server that announces a channel
3291 to the router already exists in the router (with same name but
3292 with different Channel ID), router is responsible to send
3293 Replace ID packet to the server and force the server to change
3294 the Channel ID to the one router has.
3296 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3297 client that the Channel ID has been changed by the router. The
3298 normal server sends this to the client. Client must start using
3299 the new Channel ID as the channel's ID.
3301 Implemented handling of this new type into lib/silcclient/client.c
3302 into the function silc_client_notify_by_server.
3304 * Added new function silc_idlist_replace_channel_id into the files
3305 silcd/idlist.[ch] to replace the Channel ID.
3307 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Call silc_server_command_identify_check always when processing
3310 the IDENTIFY command in silcd/command.c
3312 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3315 send keepalive packets. The packet can be sent by clients,
3316 servers and routers.
3318 Added function silc_socket_set_heartbeat into the file
3319 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3320 If not set, the heartbeat is not performed. The actual
3321 heartbeat is implemented in the low level socket connection
3322 library. However, application is responsible of actually
3325 Added silc_server_send_heartbeat to send the actual heartbeat
3326 packet into silcd/packet_send.[ch]. Server now performs
3327 keepalive with all connections.
3329 * Added silc_task_get_first function into lib/silcutil/silctask.c
3330 to return the timeout task with shortest timeout. There was a bug
3331 in task unregistration that caused problems. TODO has been
3332 updated to include that task system must be rewritten.
3334 * The client library will now resolve the client information when
3335 receiving JOIN notify from server for client that we know but
3336 have incomplete information.
3338 * Rewrote parts of silc_server_remove_from_channels and
3339 silc_server_remove_from_one_channel as they did not remove the
3340 channel in some circumstances even though they should've.
3342 * Encryption problem encountered in server:
3344 The LEAVE command used to send the Channel Key packet to the
3345 router immediately after generating it. However, the code
3346 had earlier sent Remove Channel user packet but not immediately,
3347 ie. it was put to queue. The order of packets in the router
3348 was that Channel Key packet was first and Remove Channel User
3349 packet was second, even though they were encrypted in the
3350 reverse order. For this reason, MAC check failed. Now, this
3351 is fixed by not sending the Channel Key packet immediately but
3352 putting it to queue. However, this is more fundamental problem:
3353 packets that are in queue should actually not be encrypted
3354 because packets that are sent immediately gets encrypted
3355 actually with wrong IV (and thus MAC check fails). So, packets
3356 that are in queue should be encrypted when they are sent to
3357 the wire and not when they put to the queue.
3359 However, the problem is that the current system has not been
3360 designed to work that way. Instead, the packet is encrypted
3361 as soon as possible and left to the queue. The queue is then
3362 just purged into wire. There won't be any fixes for this
3363 any time soon. So, the current semantic for packet sending
3366 o If you send packet to remote host and do not force the send
3367 (the packet will be in queue) then all subsequent packets to the
3368 same remote host must also be put to the queue. Only after the
3369 queue has been purged is it safe again to force the packet
3372 o If you send all packets immediately then it safe to send
3373 any of subsequent packets through the queue, however, after
3374 the first packet is put to queue then any subsequent packets
3375 must also be put to the queue.
3377 Follow these rules and everything works fine.
3379 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Added new function silc_server_remove_clients_by_server to
3382 remove all client entries from ID list when the server connection
3383 is lost. In this case it is also important to invalidate all
3384 client entires as they hold the invalid server entry. This
3385 fixes fatal bug when server has lost connection and will reconnect
3388 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Made some sanity checks to silc_server_daemonise like to check
3391 whether the requested user and group actually exists.
3393 * Added sanity check to SKE's silc_ske_responder_finish to check
3394 that the public and private key actually is valid.
3396 * Invalidate the client's nickname when receiving Replace ID
3397 packet and the Client ID is being replaced. This means that the
3398 server will query the nickname if someone needs it (client)
3401 * Sort the ID Cache in client library when the ID Cache data
3402 has changed (needs sorting).
3404 * Do not allow for SILC client to create several connections to
3405 several servers. The client does not support windows right now
3406 and generating multiple connections causes weird behaviour.
3408 Irssi-silc client does support windows and can handle several
3409 connections without problems, see: www.irssi.org and SILC plugin.
3411 * Fixed some places where client was added to the IDList. The
3412 rule of thumb is following (in order to get everything right):
3413 If the client is directly connected local client then the
3414 `connection' argument must be set and `router' argument must be
3415 NULL to silc_idlist_add_client function. If the client is not
3416 directly connected client then the `router' argument must
3417 bet set and the `connection' argument must be NULL to the
3418 silc_idlist_add_client function.
3420 * The funtion silc_server_packet_send_local_channel actually did
3421 not check whether the client was locally connected or not. It
3422 does that now. Fixed a bug related to LEAVE command.
3424 * Fixed Remove Channel User payload parsing bug in server's
3425 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3427 * The server's silc_server_save_channel_key now checks also the
3428 global ID list for the channel as it might not be in the local
3429 list. Fixed a bug related to LEAVE command.
3431 * Is this the end of the [<unknown>] buglet that has been lurking
3432 around for a long time? A little for loop fix in server's
3433 silc_server_command_whois_parse that is used by both IDENTIFY
3434 and WHOIS command. At least, this was a clear bug and a cause
3435 of one type of [<unknown>] buglet.
3437 * WHOIS and IDENTIFY commands call the function
3438 silc_server_command_[whois/identify]_check function even if
3439 we are not router server.
3441 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added --with-gmp configuration option. If set the GMP
3444 is always compiled in the SILC source tree. If not set then
3445 it is checked whether the system has the GMP3 installed. If
3446 it has then the GMP won't be compiled (the system's headers
3447 and library is used), if it doesn't have it then the GMP is
3448 compiled in the SILC source tree.
3450 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Changed RSA private exponent generation to what PKCS #1
3453 suggests. We try to find the smallest possible d by doing
3454 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3455 not security fix but optimization.
3457 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Added new config entry [Identity] to fork the server and run
3460 it as specific user and group. A patch from Bostik.
3462 * Imported Dotconf configuration library into lib/dotconf.
3463 This will be used to create the SILC configuration files later.
3464 It will appear in the distsribution after this commit.
3466 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * A big code auditing weekend happening. Auditing code for
3469 obvious mistakes, bugs and errors. Also, removing any code
3472 Removed files for being obsolete:
3474 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3475 inline in the file lib/silcutil/silcbuffer.h)
3477 o lib/silcutil/silcbufutil.c (the header has inline versions)
3479 Changed code to fix possible error conditions:
3481 o The buffer formatting routines now check that the destination
3482 buffer really has enough space to add the data. This applies for
3483 both buffer formatting and unformatting
3484 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3485 unformatting was changed to accomodate following rules:
3486 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3487 sent to the function while XXX_*STRING will not allocate or copy
3488 the data into the buffer. Instead it sets the pointer from the
3489 buffer into the pointer sent as argument (XXX_*STRING used to
3490 require that the pointer must be allocated already). This change
3491 makes this whole thing a bit more consistent and more optimized
3492 (note that the data returned in the unformatting with XXX_*STRING
3493 must not be freed now). The routines return now -1 on error.
3495 o Tried to find all code that use buffer_format and buffer_unformat
3496 and added return value checking to prevent formatting and
3497 especially unformatting errors and possible subsequent fatal
3500 o Changed ske->x and ske->KEY to mallocated pointers in
3501 lib/silcske/silcske.h. Fixed possible data and memory leak.
3503 o Added return value checking to all *_parse* functions. Fixed
3504 many memory leaks as well.
3506 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3507 so that buffer overflows would not happen. All code now also
3508 checks the return value as it can fail.
3510 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Added reconnection support to server if the normal server looses
3513 its connection to the router (for example if router is rebooted).
3514 The server performs normal reconnection strategy implemented
3515 to the server. Affected file silcd/server.c.
3517 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Added new packet type SILC_PACKET_SET_MODE that is used to
3520 distribute the information about changed modes (for clients,
3521 channels and clients channel modes) to all routers in the
3522 network. Updated the protocol specification accordingly.
3524 Added functions into silcd/packet_send.c and
3525 silcd/packet_receive.c: silc_server_send_set_mode,
3526 silc_server_set_mode.
3528 Added new files silcmode.[ch] into lib/silccore that implements
3529 the encoding and decoding of Set Mode Payload. Added new type
3530 SilcSetModePayload. Moved the definitions of different modes
3531 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3533 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Oops, a little mistake in server's connection authentication
3536 protocol. The protocol is not ended with FAILURE but with
3537 SUCCESS if the authentication is Ok. :) Affected file is
3540 * Implemented NICK_CHANGE notify handling in server in the file
3541 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3542 the local clients on the channel. After the changing nickname
3543 in router environment snhould work and the [<unknown>] nickname
3544 should appear no more.
3546 The silc_server_replace_id function that receives the Replace ID
3547 payload now sends the NICK_CHANGE notify type also in the file
3548 silcd/packet_receive.c
3550 * Changed WHOIS and IDENTIFY command to support the maximum amount
3551 of arguments defined in protocol specs (3328 arguments). This
3552 fixed a bug that caused problems when there were more than three
3555 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Added extra parameter, command identifier, to the
3558 silc_client_send_command so that explicit command identifier
3561 Changed that ID list routines uses specific command identifier
3562 when sending WHOIS/IDENTIFY requests to the server so that they
3563 can be identified when the reply comes back.
3565 Affected files lib/silcclient/command.[ch],
3566 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3568 * Added `sender' argument to silc_server_packet_send_to_channel
3569 to indicaet the sender who originally sent the packet to us
3570 that we are now re-sending. Ignored if NULL. Affected file
3571 silcd/packet_send.[ch].
3573 * Added some server statistics support in silcd/server_internal.h
3574 SilcServerStatistics structure and around the server code. Also
3575 send some nice statistics information when client is connecting
3578 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Fixed channel ID decoding in server's JOIN command reply in
3581 silcd/command_reply.c
3583 * Fixed braodcasting of replace ID payload to not to send it if
3584 we are standalone server in silcd/packet_receive.c.
3586 * Fixed all channel message sending routines to not to send
3587 packets to clients that has router set, since they are routed
3588 separately in the same function earlier. Affects file
3589 silcd/packet_send.c and all channel packet sending functions.
3591 * In USERS reply, res_argv[i] are not allocated, the table
3592 is allocated. Thus changed that free the table, not its
3595 * In server's whois_check and identify_check if the client is
3596 locally connected do not send any WHOIS commands - they are not
3599 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Fixed some minor bugs in client when sending WHOIS command. The
3602 arguments was in wrong order.
3604 * Removed statis function add_to_channel from server in
3605 silcd/command.c that was previously used with the joining but
3608 * Tested USERS command in router environment successfully with two
3609 routers, two servers and two clients.
3611 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Reorganized the USERS command and command reply in client library
3614 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3615 When the command is given by user we register a pending command
3616 callback that will reprocess the command after the reply has been
3617 received from the server. When reprocessing the packet we then
3618 display the information. Thus, the USERS information is displayed
3619 now in the command callback instead of in the command reply
3620 callback. The processing of the command is same as previously
3621 when server has sent the command reply in the JOINing process.
3623 * Added to USERS command in silcd/command_reply.c to join the client,
3624 we didn't use to know about, to the channel after we've created
3625 a client entry for it. Also, for clienet we did know already still
3626 check whether it is on the channel or not and add it if not.
3628 * Removed silc_server_command_join_notify as the function and its
3631 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Changed the client's pending command handling to the same as the
3634 server's pending command handling. It is also now possible to
3635 execute command reply functions from other command reply
3636 function as the function callbacks for commands and command
3637 replies are one and same. The pending commands are not static
3638 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3639 in client connection context. Thus, pending commands are server
3640 connection specific as it is convenient.
3642 Changed the function silc_client_command_pending and
3643 silc_client_command_pending_del and added new function
3644 silc_client_command_pending_check. Removed the
3645 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3648 * Added cmd_ident, current command identifier, to the client
3649 connection context in lib/silcclient/client.h to keep track on
3650 command identifiers used in command sending. Client's command reply
3651 function handling now supports the mandatory command identifiers.
3653 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3654 funtions in client to fully support pending command callbacks.
3656 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3657 as one of the arguments to the application in the command reply
3660 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3661 before first releasing SILC but came back. Now it is removed again
3662 and should come back nomore. The FORWARDED flag was used only
3663 by the JOINing procedure by forwarding the command packet to router.
3664 Now, the JOINing procedure has been changed to more generic (due
3665 to various router environment issues) and FORWARDED is not needed
3666 anymore for anything. The protocol specification is yet to be
3669 Now, removed silc_server_packet_forward from server and the flag
3670 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3672 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Renamed NAMES command to USERS command. The NAMES was named that
3675 due to historical reasons. Now it is renamed. Also, rewrote
3676 parts of the USERS command. The nickname list is not sent anymore
3677 by the server. Only Client ID and mode lists are sent in the USERS
3678 command. Changed this also to the protocol specification.
3680 The client now resolves the names and stuff after it receives
3681 the USERS list from the server when joining to the channel.
3683 * WHOIS and IDENTIFY commands has been changed to support multiple
3684 Client ID's per command. One can now search for multiple users
3685 in the network by sending only one WHOIS or IDENTIFY command.
3686 Changed the code and the protocol specifications.
3688 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3689 uses silc_server_command_whois_parse to parse the request. */
3691 * If normal server, do not parse the WHOIS and IDENTIFY requests
3692 before sending it to the router. Saves some time.
3694 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Fixed JOIN command on client library. Wrong number of arguments
3697 used to crash the client.
3699 * Added silc_server_channel_has_global function to check whether
3700 channel has global users or not.
3702 * Added silc_server_channel_has_local function to check whether channel
3703 has locally connected clients on the channel.
3705 * The silc_server_remove_from_one_channel now checks whether the
3706 channel has global users or not after given client was removed from
3707 the channel. It also checks whether the channel has local clients
3708 on the channel anymore. If it does not have then the channel entry
3709 is removed as it is not needed anymore.
3711 * The silc_server_notify now checks on JOIN notify whether the joining
3712 client is one of locally connected or global. If it is global then
3713 the channel has now global users on the channel and that is marked
3714 to the channel entry. Also, it now saves the global client to
3715 global list who is joining and JOINs it to the channel. This is
3716 for normal server, that is.
3718 Changed silc_server_send_notify_on_channel,
3719 silc_server_packet_relay_to_channel and
3720 silc_server_packet_send_to_channel check if we are normal server
3721 and client has router set (ie. global client) do not send the
3722 message to that client, as it is already routed to our router.
3724 * Implemented LEAVE notify type handling in silc_server_notify
3727 * Tested LEAVE command in router environment successfully. Tested
3728 with two routers, two servers and two clients.
3732 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3734 * Implemented SIGNOFF notify type handling in silc_server_notify
3737 * silc_server_remove_id now removes the client entry from all channels
3738 it has joined and thusly sends SIGNOFF notify type.
3740 * Rewrote the NAMES list generation in server by removing two excess
3741 loops. The lists are created now inside one loop.
3743 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * silc_server_remove_channel_user checks now also global list
3746 for channel and client.
3748 * silc_server_new_channel_user checks now both local and global
3749 list for channel and client. Fixed a bug in client id decoding.
3750 Used to decode wrong buffer.
3752 * silc_server_channel_message checks now both local and global
3753 list for channel entry.
3755 * Tested channel joining (hence JOIN) in router environment
3756 successfully. Tested with two routers, two servers and two
3759 * Tested channel message sending in router environment successfully.
3761 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Added silc_server_save_channel_key into server.[ch] to save the
3764 received channel key in Channel Key payload processing. It is
3765 also used in JOIN command reply handling.
3767 Equivalent function silc_client_save_channel_key added into
3768 client.[ch] into client library.
3770 * Changed JOIN command reply to send information whether the channel
3771 was created or not (is existing already) and the channel key
3772 payload. Changed protocol specs accordingly.
3774 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3775 the request was sent by ID and not by nickname. Crashed on
3778 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3781 now correctly save the received data.
3783 * silc_server_free_sock_user_data now notifies routers in the
3784 network about entities leaving the network.
3786 At the same time implemented functions silc_server_remove_id
3787 and silc_server_send_remove_id to receive and send REMOVE_ID
3788 packets. The packet is used to notify routers in the network
3789 about leaving entities. The ID removed will become invalid in
3792 * Added function silc_idlist_del_server into server. Removes and
3793 free's server entry from ID list.
3795 * silc_server_private_message function now checks, if we are router,
3796 that the destination ID really is valid ID, naturally.
3798 * In router when NEW_ID packet is received (for new client) the
3799 hash of the Client ID is saved in the ID Cache but the
3800 client->nickname is set to NULL, instead of putting the hash
3803 IDENTIFY command now also checks that client->nickname must be
3804 valid. If it is not if will request the data from the server who
3805 owns the client. Added new function
3806 silc_server_command_identify_check.
3808 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3809 to set the command to already allocated Command Payload.
3811 * Tested private message sending in router environment with two
3812 routers, two servers and two clients. Fixed minor bugs and now
3815 * Fixed segfault from client's NAMES command. Used to crash if
3818 * Forwarded packets must not be routed even if it is not destined
3819 to the receiver. Changed server code comply with this.
3821 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Added `require_reverse_mapping' boolean value to ServerParams
3824 structure. If TRUE (not default) the server will require that
3825 the connecting host has fully qualified domain name.
3827 If the reverse mapping is not required and hostname could not be
3828 found the IP address is used as hostname.
3830 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Implemented version string checking to both client and server.
3833 The check is incomplete currently due to the abnormal version
3834 strings used in development version of SILC.
3836 * Changed all command functions in server to use the new
3839 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Changed char *data to unsigned char *data in ID Cache system to
3842 support binary data as ID Cache data. Changed code to support
3843 binary data in lib/silccore/idcache.c.
3845 * Renamed silc_server_packet_relay_command_reply to
3846 silc_server_command_reply as it is normal packet receiving
3847 function. Rewrote the function to accept command replys for
3848 servers and not only for clients.
3850 * Mark remote router always as registered server if we are connecting
3851 to it. Otherwise, commands sent by the router to us are ignored.
3853 * All ID List find routines now returns the ID Cache Entry pointer
3854 as well if requested.
3856 * WHOIS command works now in router environment, tested with two
3857 routers, two servers and two clients.
3859 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3860 in router environment (as it is almost equivalent to WHOIS) but
3861 hasn't been tested thoroughly. Added new functions:
3863 silc_server_command_identify_parse
3864 silc_server_command_identify_send_reply
3865 silc_server_command_identify_from_client
3866 silc_server_command_identify_from_server
3868 * Disabled route cache adding because adding two different ID's with
3869 same IP replaces the old cache entry thus giving wrong route.
3870 The entry->router->connection is always the fastest route anyway
3871 so route cache may not be needed. Of course, new routes maybe
3872 established after receiving the ID when the entry->router->connection
3873 might not be anymore the most optimal.
3875 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Add route cache for received ID for fast routing.
3879 * Added silc_server_packet_route to route received packet on router
3880 that is not destined to us.
3882 * Renamed silc_server_get_route to silc_server_route_get.
3884 * Added id_string and id_string_len fields into SilcServer to
3885 include encoded ServerID for fast comparing without excess
3886 encoding of the ID's.
3888 * Cleaned up WHOIS command on server side. Added following static
3891 silc_server_command_whois_parse
3892 silc_server_command_whois_check
3893 silc_server_command_whois_send_reply
3894 silc_server_command_whois_from_client
3895 silc_server_command_whois_from_server
3897 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3898 arguments in command replies. All command functions should be
3899 updated to use this macro.
3901 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Minor typo fixes on command reply handling on server.
3905 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Added silc_server_command_add_to_channel internal routine to add
3908 the client to the channel after router has created the channel and
3909 sent command reply to the server.
3911 * Added generic silc_server_send_command to send any command from
3914 * Use static buffer with ID rendering instead of duplicating data.
3916 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Fixed a channel user mode bug when joining to a channel server gave
3919 everybody channel founder rights, oops.
3921 * We mark ourselves as the router of the incoming server connection
3922 if we are router ourselves. This way we can check in some packet
3923 sending functions whether it is locally connected server. For
3924 incoming router connections we put NULL.
3926 * For router sending packets locally means now always sending the
3927 packet cell wide; to local clients and local servers. For normal
3928 server sending packet locally means sending it to only local
3931 * Fixed the JOIN command to really work in router environment. If the
3932 channel is created it is always created by the router. Router is
3933 also responsible of making the initial joining to the channel,
3934 sending JOIN notify to the sending server and distributing
3935 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3936 does not exist server doesn't do anything else but forward the
3937 command to the router which performs everything.
3939 * Added silc_server_send_channel_key function to send the Channel Key
3942 * Added silc_server_create_channel_key to create new channel key. The
3943 channel key is now re-generated everytime someone joins or leaves
3944 a channel, as protocol dictates. Note: channel->key_len is the
3947 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3950 packet_receive.[ch] to separate packet sending and receiving
3951 routines. The server.[ch] now includes everything else including
3952 actual packet processing (writing and reading data) and other
3955 Renamed silc_server_private_message_send_internal to
3956 silc_server_send_private_message. The routine is still though
3957 used only to relay private messages as server does not send
3958 private messages itself.
3960 Renamed silc_server_new_channel to silc_server_create_new_channel
3961 and added new function sicl_server_new_channel that handles the
3962 incoming New Channel packet. Added also new sending function
3963 silc_server_send_new_channel to send New Channel Payload.
3965 * Added new function silc_server_notify to process incoming notify
3966 packet to the server/router. Server may then relay the notify
3967 to clients if needed.
3969 * Added new function silc_server_new_channel_user to process incoming
3970 New Channel User packet. Router will redistribute the packet and
3971 send JOIN notify to its local clients and locally connected servers
3972 if needed. Normal server will send JOIN notify to its local client
3973 on same channel when received this packet. Added also corresponding
3974 sending function silc_server_send_new_channel_user to sent the
3977 * Added boolean route argument to send_notif_to_channel and
3978 packet_send_to_channel functions to attempt to route the packet
3979 if it is TRUE and send only locally if it is FALSE.
3981 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * silc_server_replace_id now broadcasts the received replace ID
3984 packet if it is not broadcast packet already. The router must
3985 broadcast to inform other routers about changed ID.
3987 * Added backpointer to server's router into SilcServer context in
3988 silcd/server_internal.h.
3990 * Fixed silc_server_packet_broadcast to send correct broadcast
3993 * The channel key is now distributed to the local client as soon
3994 as it is received from the router (in router environment) so that
3995 no other packet may be sent for the channel until client has
3998 * silc_server_remove_channel_user now broadcasts the received
3999 Remove Channel User packet if it is not broadcast packet already.
4000 The router must broadcast to inform other routers about removed
4003 * Added users field into SilcPacketContext that is a reference count
4004 of the context. One can increase the reference count by calling
4005 silc_packet_context_dup which is now changed to just increase the
4006 reference count instead of duplicating the data. The reference
4007 count is decresed by calling silc_packet_context_free that will
4008 free the data after the reference count hits zero.
4010 For now on the packet context and everything allocated into it
4011 (including the raw packet from network) must be freed by calling
4012 the new silc_packet_context_free function. Added also new function
4013 silc_packet_context_alloc that must be used now to allocate the
4014 context. This also means that if a routine is asynchronous from
4015 silc_[client/server]_packet_parse_type the packet context must
4016 be duplicated by calling silc_packet_context_dup. Otherwise it
4017 gets free'd after silc_[client/server]_packet_parse_type returns.
4018 Also, one must remember that if packet is duplicated then its
4019 reference count must be decresed by calling the free function as
4020 many times as it was duplicated.
4022 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4023 from both client and server.
4025 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Made joining to a channel working in router environment.
4029 * Cleaned up JOIN command on server side and create function
4030 silc_server_command_join_channel internal routine to make the
4033 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Changed silc_command_pending list to SilcDList. Also, added
4036 `ident' field to SilcServerCommandPending structure to identify
4037 the reply and to call correct callback.
4039 Added silc_server_command_pending_check function to replace the
4040 corresnponding macro. The silc_command_pending list is not
4043 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4044 to set identifier to previously allocated Command Payload. It
4045 is used to set identifier for command when resending Command
4048 * Added silc_command_payload_encode_payload to encode Command
4049 Payload buffer from SilcCommandPayload structure.
4051 * Added silc_argument_payload_encode_payload to encode Argument
4052 payload buffer from SilcArgumentPayload structure.
4054 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Changed WHOIS command to support router connection on server side.
4057 The whois request is always sent to router unless the server is
4058 standalone server. After server has received the reply from the
4059 router will it send the reply to the client.
4061 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4062 broadcast received broadcast packet. The function is used only
4063 by router. The broadcast packet is always sent to the router's
4066 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4067 render given ID to printable string, for log files for example.
4069 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Made basic router to router connections working. At least they
4072 can now connect to each other but nothing really works the way
4073 they are supposed - yet.
4075 * Added new initiator token to RouterConnection configuration
4076 file in silcd/serverconfig.[ch]. It is used to tell whether we
4077 are the initiator to the remote router or whether we'll expect
4078 the other end to connect.
4080 * Moved registering of listener task to silc_server_init, hence
4081 the server starts listenning as soon as it is run, even if it
4082 does not have connections to other routers. Let's see how well
4085 * Changed default connection retry timeouts for more suitable in
4088 * Removed cipher and such arguments from silc_idlist_add_client
4089 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4090 Added new function silc_idlist_add_data to add the keys and stuff
4093 * Added SilcIDListData structure and added it to SilcClientEntry
4094 and SilcServerEntry as their first field in the structure. This
4095 way we can explicitly cast the ID entries to the SilcIDListData
4096 structure and get common data for the entries. In past, we had
4097 to first check what type of connection it is and then cast it to
4098 correct ID entry type. Now, we can directly cast the opaque
4099 pointer to the SilcIDListData (no matter what ID entry it actually
4100 is) and get the data needed.
4102 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4105 in some circumstances even if threre were timeout tasks, though not
4106 IO tasks, but tasks anyway. Now fixed.
4108 * Defined SilcServerConnection structure to hold connection specific
4109 stuff about directly connected servers and routers. The definition
4110 is currently in silcd/server_internal.h. I thought about having
4111 a bit more important role fro this struct but for now it is used
4112 only when connecting to other server (or router actually).
4114 * Added connecting retry support in server when connecting to
4115 router(s). The retry feature implement exponential backoff
4116 algorithm. Also, added SilcServerParams structure to hold default
4117 parameters for server. For now, it include these retry settings
4118 and are hard coded. After server is moded to be as Silc Server
4119 Library this structure will be more important.
4121 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Changed client librarys channel->clients table to SilcList and
4124 changed code accordingly.
4126 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Changed client's channel table to SilcList and changed code
4129 accordingly. Also changed SilcChannelClientEntry to include back-
4130 pointer to the channel so that client entry can use that structure
4131 as list as well and we have fast cross-reference to the channel.
4132 This change dramatically decreased the complexity of channel
4133 handling with client entry and vice versa (removed one extra
4134 loop when searching for channel entry from many functions).
4136 * Changed server->sim from table to SilcDList and changed code
4139 * NAMES command can now be used from user interface. It will show
4140 the user list on the channel, neatly.
4142 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4143 Code now saves realname of the user if it becomes available.
4145 * Renamed configure.in to configure.in.pre and made ./prepare
4146 script to automatically add correct version string to
4147 configure.in which it creates from configure.in.pre.
4149 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * NAMES command reply now shows users mode with the nickname when
4154 * Moved silc_client_ch[u]mode[_char] functions from
4155 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4156 place sucks, they are utility functions and should be in some
4159 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4161 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4164 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Added TRQ (efficient deque and list library) into lib/trq. This is
4169 a very good list library that is currently used in the SILC. Defined
4170 SilcList API over the library because I didn't like the API very
4171 much. See lib/trq/silclist.h for the API and examples of how to
4172 use the API. Fixed various places in the code to use the new
4173 SilcList API. The SilcList is meant for lists that has a structure
4174 already defined as a list. It is not suitable to add just some
4175 context to the list (in TRQ, the context is the list actually).
4177 So, I defined SilcDList that can be used for the purpose where
4178 predefined list structure does not exit. This can be used as
4179 such list. Now some context just can be added to the SilcDList.
4180 Currently this list is not used in the SILC just yet, though there
4181 are a lot places where this can replace dynamically allocated
4182 tables and I will fix these places, later, to use SilcDList.
4183 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4184 and use TRQ internally).
4186 Also fixed some annoying warning messages that the original TRQ
4187 code generated. Also minor changes to TRQ's Makefile.in.
4189 * Added support for querying by Client ID to both WHOIS and
4190 IDENTIFY commands into server, as required by the protocol.
4192 * Removed method function pointers from SilcBuffer structure. They
4193 weren't used to anything and just increased the context size for
4194 no good reason. This change also made silc_buffer_alloc and
4195 silc_buffer_free functions inline functions.
4197 * Disabled command flooding detection support until it's fixed so
4198 that it accepts commands in but does not execute them more than once
4201 * Added silc_net_localhost(), to return local hostname, into
4202 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4203 that must be initialized before calling silc_client_init.
4205 * Added new function: silc_server_send_notify_on_channels to send
4206 notify messages to all channels client has joined. It is assured
4207 that the message is sent only once per client.
4209 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4210 lib/silcutil/silcutil.[ch] as silc_format function. The new
4211 function is generic and is used by server as well, not only by
4212 the logging routines.
4214 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4215 the provided version string was not acceptable. Added new function:
4216 silc_ske_check_version into lib/silcske/silcske.h. The function
4217 must be implemented by the application (client or server) and it
4218 does not reside in the SKE library. The function checks the version
4219 string remote end sent.
4221 * Added back pointers (to opaque context and to SilcSocketConnection)
4222 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4224 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4225 duplicate packet context structure.
4227 * Changed `notify' client operation to send same arguments as client
4228 receives from server except for ID's. ID's are mapped to correct
4229 ID entry and that is returned. Also, if channel entry is not sent
4230 by server but the notify is for channel the channel entry is sent
4231 to application (otherwise application doesn't know that it is for
4232 channel (library gets it from packet's Destination ID)).
4234 * Added silc_client_remove_from_channels into client library to
4235 remove a client from all channels it has joined to. Used when
4236 received SIGNOFF notify from server. Added also new function
4237 silc_client_replace_from_channels to replace old ID entry with
4238 new ID entry on all channels. Used when received NICK_CHANGE
4241 * Fixed ID Cache list handling in silc_idlist_get_client in
4242 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4243 to get (or query) client by ID.
4245 * Updated TODO list.
4247 * Added connection authentication status message defined by the
4248 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4249 support for these into the code in client and server side.
4251 * Added generic function silc_client_send_command to send any command
4252 with variable argument list. Application should use this function
4253 to send commands if the command functions provided by the library
4254 does not suite for the application's user interface needs.
4256 * Added new `failure' client operation. Application is notified about
4257 received failure packet if client is executing a protocol. In this
4258 case the protocol's execution has failed.
4260 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4261 is required by the protocol.
4263 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4264 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4267 * Added status flag to SilcSKE object to indicate realtime status
4268 of the SKE protocol.
4270 * Application receives now exactly same command reply arguments as
4271 the library receives from server. However, if ID is received the
4272 corresponding ID entry is returned to the application (eg. Client
4273 ID is mapped to correct SilcClientEntry entry and that is returned).
4274 Changed command_reply client operation due to this change.
4276 * Changed all ID's in commands and in command replys as ID Payloads.
4277 Change affected both client and server side codes.
4279 All ID's sent in SILC network (with execption of ID's in SILC
4280 Packet header) are sent in ID Payload to support variable length
4283 * Server now notifies nick changes and notifies all clients on
4284 the channels about the new nickname (about the new Client ID,
4287 * Implemented CMODE command to change channel modes. Supports all
4288 channel modes defined by the protocol specs except ban and invite
4289 lists. (Also, private channel key mode is supported but support for
4290 setting private channel key in client is missing, thus, this mode
4291 has no effect on client side (except that server requires that the
4292 client uses private channel key and normal channel traffic does not
4295 Also, invite mode works per se, but INVITE command does not work
4296 yet correctly, so you can set channel as invite only channel but
4297 inviting clients to the channel does not work (it is yet to be
4298 thought what's the best way to do it).
4300 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4301 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4302 Implemented CUMODE command to change user's mode on the channel.
4303 Supports all modes defined by the protocol specs.
4305 * Added NAMES command reply to return users modes on the channel.
4307 * Removed unnecessary and slow ciphers from lib/silccrypt.
4309 * Set SO_KEEPALIVE option to connection sockets by default.
4311 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4313 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4314 redefined the Notify Payload into protocol specs.
4316 * Added silc_id_payload_parse_id to get ID directly from raw
4319 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4322 accept searching by Client ID as well.
4324 * Added support for LEAVE and SIGNOFF notify types in client library.
4326 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4327 to parse ID Payload from raw data.
4329 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Added flags parameter into silc_ske_assemble_security_properties
4332 function in lib/silcske/silcske.[ch].
4334 * Changed notify client operation to fit better for notify messages
4335 sent by server. The notify payload received from server is now
4336 passed to the application (after parsing it to SilcNotifyPayload).
4337 It is application's responsibility to retrieve the arguments
4338 from the payload and show the message the way it wants. The message
4339 sent by server is implementation specific.
4341 * Changed public keys to comply with the protocol specification.
4342 Old public keys are not supported anymore and are not compatible.
4344 * Removed nickname from Channel Payload as the latest draft removed
4345 it. The client must resolve the nickname from the NAMES command
4346 reply received when it joined the channel.
4348 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4350 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4352 * Fixed some errors in protocol specification drafts.
4354 * Created lib/silccore/silcnotify.c to implement Notify Payload
4355 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4356 generic payloads described by protocol specifications. The file
4357 includes implementations for ID Payload and Argument Payload.
4359 * Changed Command Payload implementation to use the new Argument
4360 Payload. Changed command_xxxx_payload to command_payload_xxxx
4361 to comply with SILC coding conventions.
4363 * Added suppport for Argument Payload handling in Notify Payload
4364 implementation as protocol requires it. Added the new support
4365 into server and client lib as well.
4367 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Added support for multiple nicknames on same channel. [n] is
4370 added locally to the nickname if there are more than one same
4371 nicknames on the channel.
4373 * Server now sends all nicknames that matched WHOIS request.
4374 Client also shows the list received from server.
4376 * Added TOPIC command to client side. User can now set and show
4377 current topic on channel.
4379 * Added MOTD command to client and server. Also, server sends the
4380 motd when client connects to the server.
4382 * Changed version strings to comply ISO 8601.
4384 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Fixed protocol error handling in client library. It should now
4387 cope even if the SKE fails for some reason.
4389 * Made new protocol specification drafts for submitting to IETF.
4391 * Implemented TOPIC command to server in silcd/command.c.
4393 * Added two new notify types into lib/silccore/silcnotify.h:
4394 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4395 notify nickname change and topic setting/change on a channel.
4397 * API change of command_reply operation in client library. The
4398 application gets now the status type received from server as well.
4400 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4404 * Cras fixed and optimized the packet handling even further and
4405 it should work now. Minor change to the prototype of function
4406 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4408 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Added new function into lib/silcutil/silcschedule.[ch]:
4411 silc_schedule_with_fd to select() a specified fd. The function
4412 returns after timeout expires or data arrives or goes. The
4413 function is used by packet routines to wait that all data is
4414 received from network.
4416 * Fixed data reading from network in lib/silccore/silcpacket.c.
4417 The code now assures that all data is read from the fd and then
4418 continues packet processing. This was a bug fix since the code
4419 used to drop some data in some circumstances.
4421 * Added new function into lib/silcclient/client.[ch]:
4422 silc_client_start_key_exchange to start key exchange after
4423 connection has been established to server. The code internally
4424 now uses this funtion but its main purpose was to provide it
4425 for applications that perform their own connecting. After
4426 application has created a connection it merely calls this
4427 function to start the key exchange between client and server.
4428 The library takes care of everything else after that.
4430 Updated also lib/silcclient/README to explain the usage of
4433 * Do not send to application information that connection has
4434 been established. Application gets notified it by connect
4437 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Applied cras's patch to add silc_schedule_one function. The
4440 function runs scheduler once and returns.
4442 * Fixed the scheduler after cras messed it up. The timeout
4443 handling works now as it's supposed to work.
4445 * Added into lib/silccore/ silcnotify.h to include notify
4446 message types support. Changed silc_server_send_notify*
4447 functions, in server.[ch], to support those new notify types.
4448 Added the support for the notify types into client library,
4449 as well. Added new notify client operation into ops.h in
4452 * Changed silc_server_packet_send_to_channel to send normal
4453 packets instead of just channel message packets. The function
4454 is now used to send the notify packets to channels. It is not
4455 used to send channel message packets anymore, as server never
4458 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4459 va_arg()s as it seems to require it nowadays. I guess, if SILC
4460 is compiled with older va_arg() the new code should work anyway.
4462 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Splitted core library. Core library (lib/silccore) includes
4465 now only SILC protocol specific core (and common) components.
4466 Created new utility library (lib/silcutil) that includes more
4467 generic purpose stuff. The stuff for util library was taken
4468 from the old core library. This was minor and easy split.
4470 * Created SILC Client Library (lib/silcclient) that includes
4471 implementation of the SILC client without user interface. This
4472 was major move from silc/ directory. The code has been changed
4473 so that it is transparent towards the user interface. The
4474 silc/ directory includes now the same user interface as before
4475 and it uses the new client library. Read lib/silcclient/README.
4476 Basicly, the client library performs everything else related
4477 to SILC except user interface handling. Also, configuration
4478 files are considered to be part of user interface and library
4479 does not handle them.
4481 This change also changed a lot of structures, function naming etc.
4482 Most important change was that SilcClientWindow object was
4483 renamed to SilcClientConnection in the client library. Created
4484 also new file lib/silcclient/ops.h. Also added new files
4485 silc/local_command.[ch] and silc/client_ops.[ch].
4487 All these changes were made to make it easier for user interface
4488 designers to create what ever user interface for the SILC client
4491 It is also expected that the server will be moved to lib
4492 directory as well and SILC Server Library will be created;
4493 sometimes in the future.
4495 * Removed Local commands from lib/silccore/silccommand.h as
4496 they are application specific and new client library does not
4497 handle any of those anymore.
4499 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4500 old client implementation in silc/.
4502 * Added support for callback functions in SILC_LOG_* macros.
4503 Application can now set its own callbacks that will be called
4504 instead of using the default functions that will always print
4505 the debug messages to stderr (or stdout). Also, debugging can
4506 now be disabled by setting silc_debug to FALSE and re-enabled by
4507 setting it to TRUE. Note, that logging will still work even
4508 if debugging is disabled.
4510 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4511 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4512 silc_log_reset_debug_callbacks.
4514 * To enable debugging in silc client one must give now -d
4515 option on command line.
4517 * Changed silc_schedule_init to automatically allocate task queues
4518 if they are not allocated before calling it.
4520 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Added GMP 3.1 into math library.
4524 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4527 a channel in SILC network. The packet is used by servers and
4528 routers to notify other routers that user has left a channel.
4529 This little feature was missing until now. Added the feature
4530 to protocol specification as well.
4532 Added functions: silc_server_send_remove_channel_user and
4533 silc_server_remove_channel_user into server.[ch].
4535 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4536 lib/silccore/silcpacket.h. However, they are not implemented
4539 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Fixed joining to a channel and sending channel messages
4542 between server and router. The channel message sending should
4543 now work inside a cell.
4545 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Fixed the private message sending between server and router.
4548 The private message sending should now work inside a cell.
4550 * Added silc_server_replace_id into server.[ch] to replace
4551 existing ID in the SILC network.
4553 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4554 and silc_idlist_replace_server_id into idlist.[ch] in server.
4556 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Fixed the server to server connections. Server can again now
4559 connect to router. Router to router connections probably does
4562 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Added dynamic protocol registering support. Now protocols can
4565 registered and unregistered on the fly. Patch by cras.
4567 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Added lib/contrib directory to hold routines that some platforms
4570 don't have but are needed by SILC.
4572 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4573 into lin/contrib to provide getopt() and getopt_long() for
4574 those who don't have it.
4576 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Added AWAY command to client. When away message is set and
4579 client receives a private message packet the client automatically
4580 replies to the sender with the away message.
4582 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4583 bug seemed to be the cause of recent problems when compiling
4586 * Added version detection support to SKE protocol specification
4587 and added the new changes to the SKE implementation as well.
4588 There were other minor changes in the SKE protocol as well.
4590 Many changes in lib/silcske/silcske.[ch] and in
4591 lib/silcske/payload.[ch].
4593 * Added ^U functionality, clear input line. Patch from cras.
4595 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Mainly small bugfixes on core library. Fixed some debugging
4598 logging and buffer overflow in silclog.c.
4600 * Updated config.sub and config.guess on the distribution tree.
4602 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added command lagging support in server. Client may execute
4605 commands now only once in two seconds.
4607 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Optimized packet reception. MAC computation and checking is now
4610 also more optimized. A lot previously duplicated code is now
4611 used as generic by both client and server.
4613 * Fixed key pair generation in clientutil.c
4615 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added into lib/silccore/silcbufutil.[ch] new function;
4618 silc_buffer_realloc.
4620 * Moved generic packet sending/encryption functions to
4621 lib/silccore/silcpacket.[ch] from client and server. Some
4622 rewriting of the functions.
4624 * Moved all generic packet reception/decryption functions to
4625 lib/silccore/silcpacket.[ch] from client and server. The
4626 packet processing is now much cleaner in both client and server.
4627 These were major changes in both client and server.
4629 * Created many common functions in server to do packet sending.
4630 Previously code were duplicated a lot, this has been removed
4633 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Rewrote major parts of the ID cache system. Don't know
4636 whether it is better now or not but at least the API is more
4639 * Major rewrite on ID cache stuff on client because of the ID
4640 cache API changes. Added idlist.c to client.
4642 * Also major rewrite on ID cache stuff on server as well.
4643 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4644 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4645 in hand, instead they are all put into the ID cache system now.
4646 All server_idlist_* routines uses ID cache now instead of
4647 traversing its own lists (those lists does not exist anymore).
4648 SilcIDList though still exists. Also, SilcXXXEntry's are
4651 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4653 * Finally made the SKE implementation compliant to the protocol
4654 specification. All mp integers are now binary encoded as
4655 opposed being HEX encoded.
4657 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4660 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4661 functions: silc_[encode/decode]_pem. Also added function
4662 silc_encode_pem_file to PEM encode with newlines ('\n') for
4665 * SILC public keys are now encoded either PEM or binary. Same
4666 option is for private keys as well. By default private keys
4667 are binary encoded and public keys PEM encoded. Silly HEX
4668 encoding were removed.
4670 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4671 function to create fingerprints.
4673 * Fixed a bug in SHA1; does not change the original data anymore.
4675 * Partly implemented INFO command on client and server side.
4676 Fixed CLEAR command. Changes to SERVER command; show current
4677 server(s) when giving command without arguments. Added
4678 VERSION command to client.
4680 * Added check to server that unregistered connections cannot
4681 execute commands (unless it is specificly allowed).
4683 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Fixed screen refresh.
4687 * Fixed channel joining bug from client. On some circumstances
4688 client tried to join to a channel it had already joined.
4690 * Added public key verification process into client's protocol.c.
4691 The client now verifies the public key from user and saves
4692 it into ~./silc/serverkeys/ directory.
4694 Added into: clientutil.[ch]: silc_client_verify_server_key.
4696 * Changed SKE protocol's silc_ske_initiator_finish function
4697 to accept callback function that verifies the received public
4698 key. Removed old silc_ske_verify_public_key function.
4700 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4703 silc_pkcs_private_key[_data]_set.
4705 * Made the password and public authentication more cleaner in
4706 server's protocol.c.
4708 * Removed historic and obsolete protocol `channel_auth' from
4709 both client and server.
4711 * Removed wrong way of sending command status messages from
4712 server to client in server's command.c. The old way violated
4713 protocol specification.
4715 Changes to silccore/silccommand.[ch]: removed
4716 silc_command_encode_status_payload -> not needed anymore,
4717 changed silc_command_encode_payload_va to accept extra
4718 argument on variable argument list. The argument type must
4719 now be provided to the function. Also, added new function:
4720 silc_command_encode_reply_payload_va which is same as
4721 normal command_encode_payload_va except command status type
4722 is provided as extra argument.
4724 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Added ~./silc directory handling. The directory includes the
4727 public and private keys for the client.
4729 Added silc_client_check_silc_dir, silc_client_create_identifier
4730 and silc_client_load_keys.
4732 * Implemented SILC protocol compliant public key. Added public
4733 and private key saving to and loading from files.
4735 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4736 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4737 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4738 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4739 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4741 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4742 silc_pkcs_load_[public/private]_key.
4744 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Added silc_server_get_route (route.[ch]) to get connection
4747 data for the fastest route for given ID.
4749 * Implemented INVITE command on client and server. The command
4750 were re-defined in the SILC Protocol Specification and the
4751 implementation now complies with the specification.
4753 * Implemented PING command on client and server.
4755 * Implemented NAMES command on client and server. The server side
4756 supports currently only normal server not router server yet.
4757 Some changes to NAMES definition in SILC protocol specification.
4759 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Implemented LEAVE command on client and server.
4763 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4764 again. This change was made to the protocol as well. Server
4765 should not violate the protocol specification anymore.
4767 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4770 was tested. SOCKS4 was not but should work anyway.
