1 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Do not add TCP_NODELAY flag if the operating system
4 does not have it defined. Affected files are
5 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
7 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Do not enable SILC_THREADS if the linking with libpthread
10 did not happen. Affected file configure.in.pre.
12 * Added notion to protocol specification that server must
13 verify the sent authentication payload with CMODE when
14 setting the channel founder key. Implemented it to the
15 server. Affected file silcd/command.c.
17 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
19 * Added _EXTRA_DIST SILC distribution variable to the
20 distributions file. It is used to conditionally add extra
21 files or directories to the specific distribution. Affected
22 files ./prepare, Makefile.am.pre and distributions.
24 Removed the `_' from the start of the distribution names.
27 * Added README.WIN32 for instructions to compile the Toolkit
30 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
32 * Fixed a double free in disconnection in the server. Affected
33 file is silcd/server.c.
35 * Fixed the lib/silcske/groups.c to work now also with GMP
36 MP library. The string conversion did not work when using
37 specific base and the base is indicated in the string as well.
39 * Created win32/ directory which now includes MSVC++ specific
40 stuff so that toolkit (DLLs) may be compiled with MSVC++.
41 It will appear only in the toolkit distribution
43 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Changed the key material distribution function in case when
46 the hash output is too short. The data is now concatenated
47 a bit differently than it used to. Made the change to the
48 SKE protocol specification.
50 * Added better GMP detection to configure.in.pre. A patch
53 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
55 * Fixed a minor bug in SKE that might cause some problem on
56 some platforms. Affected file lib/silcske/silcske.c.
58 * Added the cookie checking for initiator in the SKE. It checks
59 that the responder returns the sent cookie unmodified. The
60 affected file is lib/silcske/silcske.c. Added new SKE
61 error type INVALID_COOKIE that can be sent during the
62 negotiation. Fixed some memory leaks as well.
64 * Added the "invalid cookie" error message to Irssi SILC client's
67 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
69 * Added `task_max' field to the SilcClientParams to indicate
70 the maximum tasks the scheduler can handle. If set to zero,
71 default values are used. Affected file lib/silcclient/silcapi.h.
73 * Fixed memory leaks in silc_client_close_connection. Affected
74 file lib/silcclient/client.c.
76 * Added silc_client_del_client_entry to client library to free
77 all memory of given client entry. Affected file is
78 lib/silcclient/idlist.[ch].
80 * Added new functions silc_client_del_channel and
81 silc_client_del_server to delete channel and server entries.
82 Affected file lib/silcclient/[silcapi.h/idlist.c].
84 * Removed silc_client_del_client_by_id from silcapi.h.
86 * Fixed the INFO command to return the server's own info
87 correctly when querying by Server ID. Affected file is
90 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
92 * Removed the non-blocking settings in WIN32 code in the
93 silc_sock_[read/write] and added SleepEx instead. Affected
94 file lib/silcutil/win32/silcwin32sockconn.c. The availability
95 of input data is now checked with FIONREAD and ioctlsocket.
97 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
99 * Call silc_schedule_task_del_by_context in the
100 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
101 Affected file lib/silccore/silcprotocol.c.
103 * Call silc_protocol_cancel for active protocols in the
104 silc_server_close_connection if the funtion
105 silc_server_free_sock_user_data has not been called.
106 Affected file silcd/server.c.
108 * Generic tasks cannot be deleted using the del_by_fd
109 task deleting function since generic tasks does not match
110 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
112 * Added a notion to SILCOPER help file that the SILCOPER works
113 only on router server, not on normal server.
115 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
117 * Added for WIN32 support for the new scheduler as well.
118 Affected file lib/silcutil/win32/silcwin32schedule.c.
120 * Fixed the SHA1 implementation to work on various platforms.
122 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
124 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
125 API. It is part of the scheduler now. Everything else is
126 as previously but some functions has changed their names.
127 Checkout the lib/silcutil/silcschedule.h for the interface.
128 Updated all applications to use the new interface. Affected
129 files are lib/silcutil/silcschedule.[ch].
131 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
133 * Found a bug in the SKE implementation. The HASH value,
134 specified by the protocol, was not computed correctly. The
135 public key of the responder was not added to the computation
136 even though it is mandatory. Affected file lib/silcske/silcske.c.
137 This unfortunately causes incompatibilities with older
140 * Added WIN32 specific network init and uninit functions:
141 silc_net_win32_init and silc_net_win32_uninit to init and uninit
142 the Winsock2. Affected file lib/silcutil/silcnet.h and
143 lib/silcutil/win32/silcwin32net.c.
145 * Set the socket always to nonblocking mode on WIN32 after
146 reading data or writing data. Affected file is
147 lib/silcutil/win32/silcwin32sockconn.c.
149 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
151 * Fixed various compilation problems under WIN32. Affected
152 files lib/silcutil/win32/silcwin32thread.c and
153 lib/silcutil/win32/silcwin32schedule.c.
155 * Removed all _internal.h #includes from public header
156 files. Internal headers must never be included from
159 Removed also the lib/silcske/payload_internal.h file.
161 * All include files that may be needed (public and some others
162 included by the public headers) by application developers are
163 now copied to the ./includes directory. It does not copy any
164 internal headers. Affected file Makefile.defines.pre and all
165 Makefile.am's under lib/ and subdirs.
167 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
169 * Do not change the ~/.silc directory's permissions automatically.
170 Affected file irssi/src/silc/core/clientutil.c.
172 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
174 * Do not cancel the protocol in silc_server_close_connection
175 it might cause recursion. Now cancelled in the function
176 silc_server_free_sock_user_data. Affected file silcd/server.c.
178 * Fixed the silc_server_remove_clients_by_server to regenerate
179 the channel keys correctly finally. Added also new function
180 silc_server_remove_clients_channels to actually do it.
181 Affected file silcd/server.c.
183 * Fixed the silc_server_new_channel to not crash by giving
184 wrong router to the new channel. Affected file is
185 silcd/packet_receive.c.
187 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
189 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
190 which is given as argument to the silc_client_alloc now.
191 It can be used to configure the client and set various parameters
192 that affect the function of the client.
194 * The USERS command in server did not check whether the channel
195 is private or secret. Affected file silcd/command.c.
197 * Added new argument to the USERS command in protocol specification.
198 The USERS command now can take the channel name as argument
199 as well. Added support for this in client and server and
200 updated the protocol specs.
202 * Completed the GETKEY command in client. It can be now used
203 to fetch also servers public key not only some clients.
204 Affected files lib/silcclient/command[_reply].c.
206 * Added silc_client_get_server to return server entry by the
207 server name. Affected files lib/silcclient/silcapi.h and
210 * Redefined the IDENTIFY command in protocol specification to be
211 more generic. It now can be used to query information about
212 any entity in the SILC Network, including clients, servers and
213 channels. The query may be based either the entity's name
214 or the ID. Added support for this in both client and server.
216 Affected files silcd/command.c and lib/silcclient/command.c
219 * Optimized the WHOIS and WHOWAS commands in the server. Removed
220 the _from_client and _from_server functions. Affected file
223 * Added silc_client_get_channel_by_id_resolve to the file
224 lib/silcclient/silcapi.h to resolve channel information by
225 its ID. Added also silc_client_get_channel_by_id that
226 does not resolve it from the server.
228 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
230 * Added SilcServerEntry context into the client library
231 to represent one server. The INFO command now allocates
232 these to save the resolved server info. For now on the
233 client library will also keep information about servers,
234 connected and resolved with INFO.
236 The INFO command now allocates the SilcServerEntry context
237 and saves the server info there. The COMMAND_REPLY in
238 the INFO now returns the parameters to application in
239 same order as defined in the protocol specification.
241 The entries are cached in the client->server_cache.
243 * The INFO command is now issued after received the Client ID
244 from the server. Affected file lib/silcclient/client.c.
246 * The CMODE_CHANGE notify may now return also an SilcServerEntry
247 to the application as the mode changer might be server.
248 It is guaranteed that NULL is not returned anymore to the
249 application. Affected file lib/silcclient/client_notify.c.
251 The ID Type is now also passed to the application so that
252 it can check whether the returned entry is SilcClientEntry
255 Added new function silc_client_get_server_by_id to return
256 the server entry by ID. Affected files are the
257 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
259 * Do not create the channel in the Irssi SILC Client when issuing
260 the JOIN command but when received the sucessful JOIN command
261 reply. Otherwise the channel might get created even though we
262 could not join it. The Affected file is
263 irssi/src/silc/core/[silc-channels.c/client_ops.c].
265 * Fixed a channel joining bug in router. The router must also
266 check the channel modes, invite and ban lists etc. when serving
267 the JOIN command sent by normal server. Affected file is
268 silcd/command.c. The router now resolves the client's
269 information from the server who sent the JOIN command if it
270 does not know it, and processes the JOIN command only after
273 * Changed the SilcCommandCb to take new argument; void *context2.
274 Affected file lib/silccore/silccommand.h
276 The second argument in the command callbacks in the server now
277 includes the SilcServerCommandReplyContext if the command was
278 called as pending command callback from the command reply.
279 Otherwise it is NULL. When called as pending the status of the
280 command reply will be checked and if it was erronous the
281 error will be sent to the original sender of the command.
282 This way the client always receives the error messages even
283 though the server was actually the one who received the error
284 when it resent the command to router, for example. Affected
285 files silcd/command[_reply].[ch].
287 * Fixed sending WHOWAS command's error message to client if
288 the requested client could not be found. It was missing.
291 * Changed the CMODE and CUMODE commands reply arguments in the
292 protocol specification. The Channel ID is now sent in both
293 of the commands to identify the channel. Implemented this
294 new feature to the client and server. Affected files
295 lib/silcclient/command_reply.c and silcd/command.c.
297 * Made better checks for invite and ban lists in the JOIN
298 command in server. Affected file silcd/command.c.
300 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
302 * The server now performs the incoming host IP/DNS lookup
303 using the silc_socket_host_lookup and thus does not block
304 the server anymore. Affected file silcd/server.c.
306 * Completed the multi-thread support for SILC Scheduler in
307 the lib/silcutil/silcschedule.c.
309 * Fixed the configure.in.pre to detect the pthread correctly
312 * Fixed a deadlock in silc_task_queue_wakeup in the file
313 lib/silcutil/silctask.c.
315 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
317 * Added new function silc_schedule_wakeup that is used in
318 multi-threaded environment to wakeup the main thread's
319 schduler. It needs to be used when a thread adds a new task
320 or removes a task from task queues. After waking up, the
321 scheduler will detect the task queue changes. If threads
322 support is not compiled in this function has no effect.
323 Implemented the wakeup mechanism to both Unix and WIN32
324 systems. Affected files are lib/silcutil/silcschedule.[ch],
325 lib/silcutil/unix/silcunixschedule.c and the
326 lib/silcutil/win32/silcwin32schedule.c.
328 * Added new function silc_task_queue_wakeup to wakeup the
329 scheduler by the specified task queue. Affected file
330 lib/silcutil/silctask.[ch].
332 * The silc_socket_host_lookup_start now wakes up the scheduler
333 after adding the timeout task. Affected file is
334 lib/silcutil/silcsockconn.c.
336 * The silc_socket_host_lookup is synchronous now if the threads
337 support is not compiled in. However, the callback is still
338 called asyncronously through the scheduler, anyway. Affected
339 file lib/silcutil/silcsockconn.c.
341 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
343 * Added new function silc_socket_host_lookup to perform
344 asynchronous IP and FQDN lookups for the socket connection.
345 Affected files lib/silcutil/silcsockconn.[ch].
347 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
349 * Added SILC_MUTEX_DEFINE to define the mutex on environments
350 that may or may not compile the mutex support in.
352 Changed the silc_mutex_alloc interface. It allocates the
353 mutex now to the sent pointer and returns TRUE or FALSE.
355 Affected file lib/silcutil/silcmutex.h.
357 * Wrote the SILC Task Queue interface to support multi-threads.
358 Affected file lib/silcutil/silctask.[ch].
360 * Wrote the SILC Scheduler to support multi-threads. Affected
361 file lib/silcutil/silcschedule.c.
363 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
365 * Implemented the SILC Mutex API and SILC Thread API for WIN32
366 in lib/silcutil/win32/.
368 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
370 * Defined SILC Mutex API and SILC Thread API and implemented
371 them for Unix. Affected files are
372 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
373 lib/silcutil/unix/silcunixmutex.c and
374 lib/silcutil/unix/silcunixthread.c.
376 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Fixed the silc_server_remove_clients_by_server's channel
379 key re-generation. The hash table handling was incorrect
380 and would not work with many channels. Affected file is
383 * Fixed some memory leaks around the server code.
385 * Rewrote the silc_server_get_users_on_channel to support IPv6
386 based Client ID's. Affected file silcd/server.c.
388 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
389 specification. However, a separate document must be written
390 to define the detailed signing procedure and the payload
391 associated with the flag. Defined the flag to the
392 lib/silccore/silcchannel.h as well.
394 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
396 * Changed the dynamic tables to static size tables in the
397 lib/silccrypt/silchmac.c.
399 * Removed GCC dependencies from the code. A patch by cras.
401 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
403 * Do not show the error "Error receiving packet bla bla"
404 in server if it really was not an error (-2 means that reading
405 is pending). Affected file silcd/server.c.
407 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
409 * Fixed a possible crash in silc_server_remove_clients_by_server
410 in silcd/server.c. Fixed there also some memory leaks.
412 * Fixed the silc_idlist_replace_client_id. It could replace
413 wrong key in the hash table. Affected file silcd/idlist.c.
415 * Do not check whether there are global users on the channel
416 if the channel->global_users is FALSE. Affected functions
417 silc_server_remove_from_one_channel and
418 silc_server_remove_from_channels in silcd/server.c. Also,
419 do not check if the removed client is local as we can be
420 sure that global client was not removed from the channel
421 and checking for global users is not needed.
423 * The silc_server_remove_clients_by_server now re-generates
424 the channel keys correctly for those channels that had
425 clients removed from them. Affected file silcd/server.c.
427 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Found the reason of random crashes in the server. We weren't
430 ignoring the SIGPIPE signal (which can be sent in write())
431 and it crashed the server. Affected file silcd/silcd.c.
433 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
435 * Assure that sock->user_data is not NULL in the function
436 silc_server_packet_send in silcd/packet_send.c.
438 * Disconnect the remote connection if it could not be added
439 to any ID lists in the server. The affected file is
442 * Check in silc_server_packet_send[_real/dest] that the
443 socket is not disconnecting and ignore the data if it is.
444 Affected file silcd/packet_send.c.
446 * Define inline to __inline on native WIN32 compilation.
447 Affected file includes/silcwin32.h.
449 * Added some explicit type casts for inline code since MSVC
450 require them. Affected files lib/silcutil/silcbuffer.h,
451 lib/trq/silcdlist.h and lib/trq/silclist.h.
453 * Print warning in log files from now on if the packet
454 decryption fails. Affected file silcd/server.c.
456 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Changed the `say' client operation's interface to accept
459 new `type' argument to indicate the type of the message sent
460 by the library. The application may filter the library's
461 messages according the type. The affected file is the
462 lib/silcclient/silcapi.h.
464 * Added two new functions to lib/silcclient/silcapi.h:
465 silc_client_del_client and silc_client_del_client_by_id.
466 Affected file lib/silcclient/idlist.c.
468 * Moved the clientincludes.h from includes/ to silc/ and
469 serverincludes.h from includes/ to silcd/.
471 * The modes for the CMODE and CUMODE are now passed as
472 uint32 for application with COMMAND_REPLY. The affected
473 file is lib/silcclient/command_reply.c.
475 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
477 * /WHOIS without arguments shows client's own information.
478 Affected file lib/silcclient/command.c.
480 * Changed PING to not accept any arguments. The specs
481 says that client can ping only the connected server so
482 requiring an argument is not needed. Affected file is
483 lib/silcclient/command.c.
485 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
487 * Fixed a fatal bug in private message sending and reception
488 encryption and decryption when using private message keys.
489 The implementation was incorrect and did not follow the
490 specification. It causd that some of the message were
491 lost since it did not use the sending and receiving keys
492 as the protocol suggests. This has been fixed and will cause
493 incompatibilities with older clients when sending private
494 message encrypted with private message keys. Affected files
495 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
496 and various other in Irssi SILC Client.
498 Added `responder' boolean argument to the functions
499 silc_client_add_private_message_key[_ske] to indicate when
500 the key is added as responder or initiator of the key
503 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Removed the silc_ske_check_version function and created
506 a SilcSKECheckVersion callback. Added also a function
507 silc_ske_set_callbacks that is now used to set all SKE
508 callbacks. The callback functions are not given to
509 the SKE functions anymore, but this function is used to
512 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
514 * Added `silc_version' argument to the silc_client_alloc
515 to define the version of the application for the library.
516 The library will use the version string to compare it
517 against the remote host's (usually a server) version
518 string. Affected file lib/silcclient/silcapi.h
520 * Added the KE protocol context to Key Agreement context
521 in client library so that we can abort the SKE if it
522 is in process when we get timeout. Affected file is
523 lib/silcclient/client_keyagr.c.
525 * Do not resolve the client ID forever if it returns in the
526 first time that such client does not exist. This was done
527 for example with private message. Affected file is
528 lib/silcclient/client_prvmsg.c.
530 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
532 * Do not add regex.h for WIN32. The affected file
533 includes/silcincludes.h.
535 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
536 not work yet 100%. It generates the DLL's automatically
537 when compiling with --with-win32 under cygwin.
539 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
541 * lib/contrib/regex.c is not compiled on WIN32.
543 * Added silc_net_get_socket_opt function to the
544 lib/silcutil/silcnet.h.
546 * Added includes/silcwin32.h for WIN32 specific includes
549 * Do not use ptime structure or any of the posix process
550 functions on WIN32 in lib/silccrypt/silrng.c.
552 * Added silc_gettimeofday to provide generic function
553 for struct timeval on all platforms. Added the function
554 to lib/silcutil/silcutil.h.
556 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
558 * Moved the lib/silccore/silcsockconn.[ch] to the utility
559 library as they clearly belong there. As a plus side we
560 can make the actual socket connection routines platform
563 Added also new generic function silc_socket_read and
564 silc_socket_write (that used to be silc_packet_[read/write].
565 The implementation of these are platform specific.
567 * Added WIN32 specific routines of silc_socket_[read/write]
568 to lib/silcutil/win32/silcwin32sockconn.c.
570 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
572 * Added preliminary support for native WIN32 compilation under
573 cygwin (using the -mno-cygwin option for GCC) to the
574 ./configure.in.pre. The --with-win32 now prepares the
575 compilation for native WIN32.
577 * Rewrote the SILC Scheduler interface in the file
578 lib/silcutil/silcschedule.h. The scheduler is now context
579 based and does not have anymore any global static scheduler.
580 Moved the Unix scheduler to the lib/silcutil/unix/ directory
581 and created lib/silcutil/win32 directory for WIN32 based
584 * Added Unix specific network routines to the
585 lib/silcutil/unix/silcunixnet.c and the old
586 lib/silcutil/silcnet.c includes now only generic routines.
588 Added WIN32 specific network routines to the
589 lib/silcutil/win32/silcwin32net.c.
591 * Added Unix specific utility functions from the
592 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
594 * Added WIN32 SILC Scheduler to the file
595 lib/silcutil/win32/silcwin32schedule.c. The code is of course
598 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
600 * Do not handle JOIN notify in the server if the target client
601 is not registered (idata->registered == FALSE). The affected
602 file is silcd/packet_receive.c.
604 * Update the nickrec->founder in event_cumode in the Irssi SILC
605 client. Affected file irssi/src/silc/core/silc-channels.c.
607 * Fixed the CUMODE_CHANGE notify handling in the server when
608 server and router are announcing their clients on channels.
609 Now the mode changes are saved and notified correctly. The
610 affected file is /silcd/packet_receive.c.
612 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
613 They really did not replace the cache entry in the ID Cache.
614 Now they do that. Affected file silcd/idlist.c.
616 * Fixed the KICK notify handling in the Irssi SILC client to
617 update the channel records so that the kicked client does not
618 appear to be on the channel. The affected file is
619 irssi/src/silc/core/silc-channels.c.
621 * Always update the conn->current_channel when executing command
622 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
624 * Fixed the KILL notify handling in Irssi SILC client to remove
625 the killed client on all channels.
627 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
629 * Fixed the silc_parse_command_line to remove extra spaces
630 from the start and end of the arguments. Affected file is
631 lib/silcutil/silcutil.c.
633 * Cancel and free any active protocol in the function
634 silc_server_close_connection. Affected file silcd/server.c.
636 * Cancel and free any active protocol in the function
637 silc_client_close_connction. Affected file is
638 lib/silcclient/client.c.
640 * Do not execute the KILL command for clients that are in
641 history (ie. they are not in the network). Affected file is
644 * Fixed KILL notify handling, client does not crash anymore.
645 Affected file irssi/src/silc/core/silc-channels.c.
647 * Reduced the default packet buffer size from 2048 to 1024 in
648 lib/silccore/silcpacket.c.
650 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
651 counter to the SKE context that is incresed when the SKE library
652 performs async operation outside the library. If the outside
653 process frees the SKE context and FREED status will be set
654 and the library will detect after the sync operation that the
655 libary is freed. The affected files are
656 lib/silcske/silcske[_status].[ch].
658 * Resolve the client entry information in the function
659 silc_client_channel_message to assure that NULL pointer is not
660 passed as client entry to the application. */
662 * Fixed the task timeout calculation to assure that there is
663 never negative timeouts. The affected file is
664 lib/silcutil/silcschedule.c.
666 * Fixed the channel user mode notification sending in server.
667 It was sent point-to-point to the router (or to server by router)
668 but it needs to be destined to a channel. The routines now
669 supports sending the channel user mode notifys to the channels
670 when announcing clients and channels. Affected files are
671 silcd/server.c and silcd/packet_receive.c.
673 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
674 It did not actually replace the old channel entry in the cache.
675 Affected file lib/silcclient/client_notify.c.
677 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Fixed a possible crash in silc_packet_send_prepare. It now
680 assures always that there is enough space in the buffer and
681 at the tail area of the buffer (for MAC).
683 Fixed the inbound buffer reallocation in silc_packet_read.
684 It was old code and did not handle the reallocation correctly.
687 The affected file is lib/silccore/silcpacket.c.
689 * Fixed buffer overflow in silc_parse_nickname in the file
690 lib/silcutil/silcutil.c.
692 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * make install generates new server keys only if there is not
697 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
700 Added check that if the NOREPLY is set then we will not send
701 the away message. This avoids infinite loop of away messages
702 if both clients are away. The affected file is
703 lib/silcclient/client_prvmsg.c.
705 * Fixed client crash if /NICK was given without arguments.
706 Affected file lib/silcclient/command.c.
708 * Server does not send the invite list in INVITE command back
709 to the client if the list was not altered. Added this notion
710 to the protocol spec as well. Affected file silcd/command.c.
712 Fixed possible crash in INVITE command by checking the
713 value of silc_server_get_client_route command.
715 * Fixed the INVITE notify type handling. The arguments are now
716 taken in correct order and client does not crash. The affected
717 file is irssi/src/silc/core/silc-channels.c.
719 Removed the "Inviting xxx to channel" message from the
720 client library away and let the application handle it.
721 Affected file lib/silcclient/command.c. Added that message
722 to Irssi SILC client's message formats.
724 * Fixed CMODE command crash in client. It now checks the
725 amount of arguments correctly and does not crash. The affected
726 file is lib/silcclient/command.c.
728 * Do not create new channel automatically in silc_channels_join
729 but check whether the channel by that name already exists.
730 Affected file irssi/silc/core/silc-channels.c.
732 * Do not send the SERVER_SIGNOFF to router if the disconnected
733 entity was the router. Affected file silcd/server.c.
735 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
736 SILC client as it was missing from there.
738 Added the handling of the KICK notify to the Irssi SILC client
739 as it was missing. Added "you have been kicked" message to
740 Irssi SILC client's message modules formats.
742 Added the handing of the KILL notify to the Irssi SILC client
743 as it was missing. Added the kill message module formats
746 The affected file is irssi/src/silc/core/silc-channels.c.
748 * The router did not save the channel mode the server announced.
749 Affected file silcd/packet_receive.c.
751 * Fixed a possible crash in INFO command in server. If the
752 server did not provide the server info it crashed. Affected
753 file silcd/command.c.
755 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
757 * Fixed the GETKEY command in the server to check also the
758 global list. Otherwise the GETKEY would not work correctly
759 in normal SILC server. Affected file silcd/command.c.
761 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
763 * Fixed GETKEY crash, it crashed if the command did not succseed.
765 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
768 is now real and not just an macro interface to GMP.
770 Removed the entire GMP from the source tree and imported new
771 NSS MPI library instead. Reason for removing GMP is that it is
772 extremely large and compiles extremely slow. The NSS MPI
773 is only a few files and compiles in less than 10 seconds.
774 The speed is also about the same as GMP. The MPI is imported
777 If the system has GMP installed we will still use the GMP.
778 If it is not then the NSS MPI will be compiled.
780 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Merged a long nickname (127 characters long) crash bugfix from
783 Irssi CVS tree. Affected file irssi/src/core/misc.c.
785 * Merged a freed memory reference bugfix from Irssi CVS tree.
786 Affected file irssi/src/core/commands.c.
788 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Added the server's public key sving and verification to the
791 server when performing the SKE. This was missing and the
792 remote server's (or router's) public key was accepted without
793 checking whether we have it previously or trust it at all.
794 Affected file silcd/protocol.c.
796 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Check in the silc_server_timeout_remote if protocol is active
799 and make sure that the protocol's final callback is called so
800 that all memory if freed. Affected file silcd/server.c.
802 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * silc_server_whois_send_reply crashed the server if the nickname
805 was 127 characters long. Affected file silcd/command.c.
807 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Added sanity check to the silc_server_new_client. If the hostname
810 is provided inside username then check that the provided hostname
811 really is the same as the resolved one. If the hostname was not
812 resolved then check it from the public key. Affected file is
813 silcd/packet_receive.c.
815 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
816 if the server disconnected us and the connection is not valid
817 anymore. Affected file irssi/src/silc/core/silc-channels.c.
819 * Moved the silc_client_[chmode|chumode|chumode_char] away from
820 the library to the lib/silcutil/silcutil.[ch].
822 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Close log file after open. Affected file
825 lib/silcutil/silclog.c.
827 * Check whether sock == NULL in silc_client_send_packet and return
828 if it is. Affected file lib/silcclient/silcclient.c.
830 * Check rec->entry == NULL in the Irssi SILC Client before
831 sending the channel message. Affecte file is
832 irssi/src/silc/core/silc-servers.c.
834 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Merged a splitted window bugfix from Irssi CVS tree. The
837 affected file is irssi/src/fe-text/textbuffer-view.c.
839 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
840 It did not print nickname.
842 * Improved the distributions system a bit.
844 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
847 irssi/src/fe-text/gui-window.c.
849 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
850 to in-active server. The affected file is
851 irssi/src/silc/core/client_ops.c.
853 * Resolve the client in USERS command reply if the entry does
854 not have username resolved. The affected file is
855 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
856 command to WHOIS command to really resolve stuff. The USERS
857 is not used any more in any critical section so WHOIS can
858 be used even though it might be slower than IDENTIFY.
860 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
863 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Changed the protocol API a bit more consistent in the
866 lib/silccore/silcprotocol.[ch].
868 * Changed the following headers to ROBODoc format:
870 lib/silccore/silcpayload.h
871 lib/silccore/silcprotocol.h
872 lib/silccore/silcsockconn.h
874 All core library headers are now formatted.
876 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Fixed a bug in Irssi SILC client; do not show that you are
879 server/router operator if you really are not. Affected file is
880 irssi/src/silc/core/client_ops.c.
882 * Renamed silc_command_free_payload to silc_command_payload_free.
883 Affected file lib/silccore/silccommand.h
885 * Added silcmath.h to include the prototoypes of various routines
886 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
889 * Changed the following headers to ROBODoc format:
891 lib/silccore/silcchannel.h
892 lib/silccore/silccommand.h
893 lib/silccore/silcid.h
894 lib/silccore/silcidcache.h
895 lib/silccore/silcmode.h
896 lib/silccore/silcnotify.h
897 lib/silccore/silcpacket.h
898 lib/silcmath/silcmath.h
900 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
902 * Added checking to the server code not to start the server if
903 ciphers and stuff are not configured properly. Affected files
904 silcd/serverconfig.[h] and silcd/server.c.
906 * Changed the layout of the header files of the public interfaces
907 in the SILC libraries. The new layout supports ROBODoc
908 documentation tool (and some others) so that it is easy to create
909 a library reference manual. All the other headers and source
910 code must still follow the CodingStyle document. Also source
911 code must not include these ROBODoc stuffs, only the headers.
912 Furthermore, all public interface headers must now be named
913 by using `silc' prefix, example: silcapi.h, silccipher.h.
914 Some files were renamed due to this. All the other headers
915 must not be used as public interfaces. I will update the
916 CodingStyle document later. Changed following headers, so far:
918 lib/silcclient/silcapi.h
919 lib/silccore/silcauth.h
920 lib/silccore/silcprivate.h
921 lib/silccrypt/silcdh.h
923 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Removed silc_client_packet_send_flush from the client library
928 as it is not needed. Affected file lib/silcclient/client.[ch].
930 * Added printing of message of unresolved authentication method
931 to the Irssi SILC client. Added it to the module formats.
932 Removed the same message from the client library.
934 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * Added new distribution feature, DISTLABEL. Every distribution
937 can define own preprocessor label that can be used in the
938 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
939 file distributions, acconfig.h.pre and prepare.
941 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Added Makefile.defines_int to include the actual definitions
944 for Makefile.defines.in. Tested the new distribution system,
945 created distributions and tested installation.
947 * Added AWAY message printing to the Irssi SILC client. Added
948 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
950 * Added SCONNECT command to call the SILC's CONNECT command.
951 Cannot use CONNECT directly since Irssi uses that internally.
952 Affected file irssi/src/silc/core/silc-servers.c.
954 Added ACTION local command. It is same as ME command but takes
955 the channel as mandatory argument.
957 Rewrote some of the Irssi's help files to suite for SILC
960 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Added Makefile.defines[.in] that should for now on be included
963 in all Makefile.am file in the source tree. That file includes
964 all common compilation definitions for SILC source tree.
966 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Minor changes to the ./prepare script to change the package
969 name according the distribution name to the configure.in.
971 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Created new distribution system. Added file `distributions'
974 that defines all the distributions that can be created out of
975 the SILC source tree. The ./prepare script now reads that
976 file to determine how to prepare the distributions. The
977 first argument to the ./prepare is the name of the distribution
978 and second is the version of the distribution. If given
979 without arguments it creates the default (toolkit) distribution
980 with the default version (defined in ./prepare).
982 All Makefile.am files that are subject to the distributions
983 are now named as Makefile.am.pre. These are ./Makefile.am
984 and lib/Makefile.am. Others may be changed later.
986 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Added invite list, ban list, some key management and connection
989 error message printing to module formats in the Irssi SILC client.
991 * Added new silc_client_set_away_message to set the away message
992 that is back to the person who sent private message. The
993 affected file lib/silcclient/silcapi.h and the
994 lib/silcclient/client_prvmsg.c.
996 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Fixed the private message sending in the Irssi SILC client,
999 added local command KEY to the Irssi SILC client.
1001 Added key management and key agreement message formats to the
1002 irssi/src/fe-common/silc/module-formats.[ch].
1004 Added USERS (alias WHO) printing, server/router operator
1005 indication and LIST command printing to the module formats.
1007 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Fixed channel joining notify handling, cumode notify handling
1010 from Irssi SILC client.
1012 * Added SILC specific module-formats to the Irssi SILC client so
1013 that SILC specific message hilighting, colors etc is possible.
1014 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1016 Added channel mode, channel user mode, actions, notices,
1017 whois and whowas printing to the the module-formats.c.
1019 * Fixed a bug in channel deletion in the server. The channel
1020 is not left to the cache even if the channel founder auth mode
1021 is set when there are no users anymore on the channel. Affected
1022 file silcd/server.c.
1024 * The silc_net_localhost now resolves the entire hostname including
1025 the domain name. Affected file lib/silcutil/silcnet.c.
1027 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Changed the ask_passphrase client operation to be ascynchronous.
1030 It has now a completion callback and a context that the
1031 application must call after it has got the passphrase from
1032 the user. Affected files lib/silcclient/silcapi.h,
1033 lib/silcclient/protocol.c, lib/silcclient/command.c and
1036 Added SilcAskPassphrase callback that the application calls
1037 to deliver the passphrase to the library.
1039 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1040 The public key verification and especially a certificate
1041 verification is asynchronous procedure.
1043 Added new SILC_SKE_STATUS_PENDING status to indicate the
1044 request is pending and a callback will be called to finalize
1047 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1048 indicate that remote end did not send its public key (or
1049 certificate), even though we require it. Added check for this
1050 condition in the SKE. This was a security bug, now fixed.
1052 Defined new SilcSKEVerifyCbCompletion callback that is called
1053 when the verification process is completed.
1055 The affected files lib/silcske/silcske_status.h and
1056 lib/silcske/silcske.[ch].
1058 * Changed the verify_public_key client operation to be async
1059 as well. Defined SilcVerifyPublicKey callback that is used to
1060 indicate the success of the public key verification process.
1062 Changed the server and client to use the new async client
1065 * Changed the Irssi SILC client's internal scheduler to be called
1066 twice as many times as it used to be. As a result the client
1067 should be a bit faster now. Affected file is
1068 irssi/src/silc/core/silc-core.c.
1070 * Added support to Irssi SILC client of asynchronous public key
1071 verification and passphrase inquiry. Affected file is
1072 irssi/src/silc/core/silc-core.c.
1074 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Do not say "You have left channel %s" in client library.
1077 Moved it to the application. Affected files are
1078 lib/silcclient/command.c and silc/client_ops.c.
1080 * Fixed silc_client_get_clients. Command context was not
1081 duplicated and was freed memory in the callback. Affected
1082 file lib/silcclient/idlist.c.
1084 * Do not say "you are now talking..." on JOIN command in the
1085 client library. The appliation must handle it.
1087 * Do not say ".. changed topic to" in command reply in the
1088 client libary. The application must handle it.
1090 * Fixed TOPIC command sending in the client library.
1092 * Fixed a memory leak in silc_client_command_free in the file
1093 lib/silcclient/command.c.
1095 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Imported a modified version of Irssi client to the source tree.
1098 The Irssi will be used to create a new client called
1099 Irssi SILC. Imported to irssi/.
1101 Added silc_core_init_finish function to the Irssi. Affected
1102 file irssi/configure.in.
1104 A lot changes in the Makefile.ams around the irssi tree.
1106 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Do not rehash if the new size is same as the old size of the
1109 hash table, in the silc_hash_table_rehash*. The affected file
1110 lib/silcutil/silchashtable.c.
1112 * Replaced hash_table_del_by_context calls from the server
1113 (when channel->user_list and client->channels) to the
1114 hash_table_del as it is sufficient and faster.
1116 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Added silc_hash_table_list, silc_hash_table_get and the
1119 SilcHashTableList structure to provide an alternative way to
1120 traverse the hash table. The affected files are
1121 lib/silcutil/silchashtable.[ch].
1123 * Changed the server's idlist routines to use the hash table
1124 routines to optimize the code.
1126 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Replaced the client entry's `channel' list and channel entry's
1129 `user_list' list to hash tables for optimized lookup. Changed
1130 the code to use the hash table interface around the code.
1131 Affected file lib/silcd/idlist.[ch].
1133 * Added `auto_rehash' boolean argument to the function
1134 silc_hash_table_alloc to indicate whether the hash table should
1135 auto-rehash when it thinks is appropriate time. It will
1136 increase the hash table size if the there is twice as much
1137 entries in the table than the size of the table, and will
1138 decrease the size if there are twice as less entries than
1139 the size of the table.
1141 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1145 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * silc_idcache_purge_by_context deletes the entry now by context
1148 as it is supposed to do. Affected file lib/silccore/idcache.c.
1150 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1151 client is not anymore valid (WHOWAS givens the info) and not
1152 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1154 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Removed the `data' and `data_len' arguments from the ID Cache
1157 interfaces and added `name' argument. ID Cache does not handle
1158 anymore the binary data only a names associated with given ID.
1160 * When hashing a Client ID with silc_hash_id the entire ID is
1161 not hashed anymore, instead only the hash of the Client ID is
1162 hashed. This way we can access the Client ID from the cache
1163 with Client ID but with the hash of the ID (which is a hash of
1164 the nickname) as well without any difference in performance.
1166 Added also silc_idcache_find_by_id_one_ext to do one on one
1167 searching when we have the actual ID. Added also function
1168 silc_hash_client_id_compare. The affected files are
1169 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1171 * When hashing the name associated with a ID it is always done
1172 in lowercase. This way we can access the cache without worrying
1173 about case-sensitivity, even though, for example nicknames are
1176 * Fixed a bug in server with channel message sending. It put
1177 wrong ID type as destination ID. The affected file
1178 silcd/packet_send.c.
1180 * silc_idcache_del_by_context now deletes from all hash tables
1181 by context. Affected file lib/silccore/idcache.c.
1183 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1185 * Changed the client library to use the new ID Cache interface.
1186 Changes around the source tree.
1188 * Added silc_hash_table_rehash_ext to rehash with specific
1189 hash function. Affected file lib/silcutil/silchashtable.[ch].
1191 * Added silc_hash_string_compare to compare two strings in the
1192 hash table. Affected file lib/silcutil/silcutil.[ch].
1194 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Added new function silc_idcache_del_by_context into the
1197 lib/silccore/idcache.[ch].
1199 * Changed the server's ID list routines to use the new ID Cache
1200 interface. Changes around the source tree.
1202 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Added silc_hash_table_del[_by_context]_ext functions in to the
1205 lib/silcutil/silchashtable.[ch].
1207 Removed silc_hash_table_find_all* routines and added new
1208 silc_hash_table_find_foreach to replace them.
1210 Added silc_hash_table_replace_ext function as extended
1211 replacing function. Separated the simple hash table interface
1212 from the extended hash table interface in the file
1213 lib/silcutil/silchashtable.h.
1215 * Fixed minor bugs and changed it to use some of the new
1216 hash table functions in lib/silccore/idcache.c
1218 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Added new function silc_hash_table_find_all to return all keys
1221 in the hash table by the specified key. As the hash table is
1222 collision resistant it also makes it possible to have several
1223 duplicate keys in the hash table. This function may be used to
1224 find all of the keys from the hash.
1226 Added user_context arguments to the SilcHashFunction,
1227 SilcHashCompare and SilcHashDestructor to deliver user specified
1230 Added new fuctions silc_hash_table_find[_all]_ext to do
1231 extended lookup with specified hash and compare functions and
1232 specified user contexts.
1234 Added new function silc_hash_table_add_ext to add the key
1235 with specified hash function and user context.
1237 Added new function silc_hash_table_foreach to traverse all
1238 entrys in the hash table. Added SilcHashForeach callback
1241 Added new function silc_hash_table_del_by_context to delete
1242 the entry only if the context associated with the key matches.
1244 Affected files are lib/silcutil/silchashtable.[ch].
1246 * Removed silc_hash_[server/client/channel]_id and added just
1247 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1248 silc_hash_id_compare to compare two ID's using as the hash table
1249 comparison function. Added also silc_hash_data to hash
1250 binary data and silc_hash_data_compare to compare it.
1252 * Removed silc_idlist_find_client_by_hash as it is not needed
1253 anymore. Affected file silcd/idlist.[ch].
1255 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1256 to use internally the SilcHashTable. The new ID Cache is a lot
1257 faster than the old one. Some of the ID Cache interface was also
1258 rewritten and obsolete and stupid functions were removed.
1260 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1262 * Added entry_count field to the SilcHashTable to keep the number
1263 of the entries in the table. Implemented the function
1264 silc_hash_table_rehash. Added new function
1265 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1267 Fixed a minor bug in silc_hash_table_free.
1269 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1270 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1271 into the lib/silcutil/silcutil.[ch].
1273 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Implemented a collision resistant hash table into the
1276 lib/silcutil/silchashtable[ch]. See the header and the source
1277 for the SilcHashTable API.
1279 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Merged dotconf version 1.0.2 into lib/dotconf.
1283 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1285 * Do not compile anything in lib/silcsim/* if the SIM support
1286 is not enabled. The tree should now compile without problems
1289 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Compiled the SILC under cygwin. Compiled and tested briefly
1292 without problems. More tests needed. The SIMs didn't compile
1295 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1297 * Fixed possible crash in silc_get_username in the
1298 lib/silcutil/silcutil.c.
1300 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Fixed a va_arg in silc/client_ops.c.
1304 * Oops, RC5 routines were named AES and caused some problems
1305 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1307 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Added new SilcIDIP structure into the lib/silccore/id.h and
1310 replaced the old `ip' fields from all SILC ID's to that type.
1311 This is a step towards IPv6 support.
1313 The silc_id_get_len takes now the ID as an extra argument.
1314 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1315 both IPv4 and IPv6 based ID's.
1317 The affected files are lib/silccore/id.[ch] and other files
1318 around the tree using these routines.
1320 * Removed the ID length arguments in server from various
1321 silc_server_send_notify_* routines -> they are not needed
1324 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1326 * Fixed memory leak in silc_encode_pem_file in the file
1327 lib/silcutil/silcutil.c.
1329 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1331 * Check minor version as well in the SKE. Affected files are
1332 silcd/protocol.c and lib/silcclient/protocol.c.
1334 * Added --identifier option to the server so that an identifier
1335 can be when creating the public key for the server. Affected
1336 file is silcd/silcd.c.
1338 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1339 lib/silccrypt/silcpkcs.c.
1341 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Register default ciphers and stuff when using -C option with
1344 the server. Affected file sildc/silcd.c.
1346 * Put back the servers public key filename format, it is better
1347 than the new one. For now, the client keys are saved with the
1348 new filename format. The affected file silc/client_ops.c.
1350 * Implemented the Cipher API for the rest of the ciphers that
1351 did not implement it or implemented it the wrong way.
1353 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Register default ciphers and stuff when using the -S option
1356 in the client. Affected file silc/silc.c. Same also when
1357 creating new key pair with -C option.
1359 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1361 * Fixed the silc_verify_public_key client operation function to
1362 save the public keys differently. The fingerprint is now
1363 used as filename and not the hostname. This way also the
1364 client keys are saved uniquely and not with hostnames. The
1365 affected file is silc/client_ops.c.
1367 * Trimmed the silc_hash_fingerprint function to remove extra
1368 whitespaces from the end of the fingerprint. The affected
1369 file is lib/silccrypt/silchash.c.
1373 * Added silc_cipher_register_default function to register all
1374 default ciphers. It can be used when configuration files
1375 does not exist and the application does not want any specific
1376 ciphers in any specific order.
1378 The SilcDList is now used as silc_cipher_list dynamically
1379 allocated cipher list. Removed the static list all together
1380 and now all ciphers must be allocated to the dynamic list.
1381 The silc_cipher_alloc routine was changed to check only the
1384 All silc_cipher_* routines that used to return int returns
1387 The affected files lib/silccrypt/silccrypt.[ch].
1389 * The same thing was done to silc_hash_* as for silc_cipher_*
1390 routines. Affected files lib/silccrypt/silchash.[ch].
1392 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1393 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1394 Added also silc_pkcs_[un]register[_default] functions.
1395 Removed the data_context from the PKCS API.
1397 * Added silc_hmac_register_default function to register default
1398 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1399 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1400 to unregister all hmacs at once.
1402 * Register the default ciphers, hash functions, PKCSs and HMACs
1403 if client's configuration file does not exist. The affected
1406 * The client did not load the hash functions from the SIM
1407 modules at all. Added support for this. Affected file is
1408 silc/clientconfig.c.
1410 * When decoding public key with silc_pkcs_public_key_decode, check
1411 the supported algorithm only if PKCS are registered. Affected
1412 file lib/silccrypt/silcpkcs.c. The same was done with the
1413 silc_pkcs_private_key_decode.
1415 * Fixed the SILC List routines to keep the list always in order.
1416 It used to change the list's order when traversing the list but
1417 not it preserves the order. Affected file lib/trq/silclist.h.
1419 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Added the client library to use the SilcSocketConnection's
1422 reference counter (by silc_socket_dup) to prevent the bug that
1423 the socket object may be freed underneath async operation.
1425 * The name resolv library checking fixes in the configure.in.pre.
1428 * Created new version of the protocol drafts for future
1429 development. The -03 drafts are the ones that will be changed
1430 in the trunk now and the -02 will remain as they are.
1432 * Send list of CUMODE notifys to the router when announcing
1433 the channel users to the router. Affected file silcd/server.c.
1434 If the router receiving channel founder CUMODE for a channel
1435 that already has channel founder it will send CUMODE notify
1436 to the sender to remove the channel founder rights from the
1437 announced client. Affected file silcd/packet_receive.c.
1439 * The CUMODE notify may now use Server ID as well as the entity
1440 who changes the mode. Updated protocool specs.
1442 * Updated INSTALL and README files.
1444 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * New web pages in the http://silc.pspt.fi. The pages was
1451 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1453 * Implemented the [DenyConnectin] config section in the server.
1454 Added silc_server_config_denied_conn to check whether incoming
1455 connection is denied. Affected file silcd/serverconfig.[ch].
1457 * Do not check the ports when checking the incoming configuration
1458 data if the port is 0, meaning any. Affected file is
1459 silcd/serverconfig.c.
1461 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1463 * Fixed buffer overflow in silc_string_compare in the file
1464 lib/silcutil/silcutil.c.
1466 * Fixed double free in silc_server_command_leave in the file
1469 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Fixed the version checking in the server. Affected file is
1474 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Fixed the configuration data fetching when accepting new
1477 connections in the server. Affected file silcd/server.c.
1479 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * Added `sender_entry' argument to the function
1482 silc_server_packet_relay_to_channel so that we can check
1483 whether some destination actually belongs to the same route
1484 the sender belongs (ie, we must not resend the packet to the
1485 sender). Affected file silcd/packet_send.[ch].
1487 * Added `servername' field to the SilcClientEntry in the server
1488 to hold the name of the server where client is from. Affected
1489 file is silcd/idlist.h.
1491 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1493 * Moved the channel message encrypting in the router betwen
1494 router connections from silc_server_channel_message to the
1495 silc_server_packet_relay_to_channel since we want to check
1496 whether we have anybody channel before encrypting anything.
1497 Affected files silcd/packet_[receive/send].c.
1499 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Fixed the [AdminConnection] server config section to support
1502 multiple entries. Affected file silcd/serverconfig.c.
1504 * Added support into the server to check the validity of the
1505 incoming connection before executing any KE or authentication
1508 * The connection configuration is now saved to the KE and
1509 connection auth protocol contexts and not fetched anymore in
1510 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1512 * The local hosts listenning address and port is also resolved
1513 now when starting the server. We want to have the socket object
1514 to include the real address and port for the listener. Added
1515 new function silc_net_check_local_by_sock into the files
1516 lib/silcutil/silcnet.[ch].
1518 * Fixed a broadcast bug in server -> do not broadcast if we
1521 * Fixed a routing bug. Do not route broadcast packets ever.
1522 Broadcast packets must be processed always and not routed since
1523 they may be destined to some other host than yourself and thus
1524 would get routed without no good reason. Affected file is
1527 * Added function silc_server_config_is_primary_route to check
1528 whether primary router connection has been configured (a router
1529 configuration that we are initiating). If there is not, we
1530 will assume that there is only two routers in the SILC network
1531 and we will use the incoming router connection as our primary
1532 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1534 * Changed the order of the broadcasting. Broadcast _after_ the
1535 packet has been processed not before. Affected file is
1538 * Fixed a [ClientConnection] parsing bug. The port was never
1539 parsed correctly thus resulting to port 0. Affected file
1540 silcd/serverconfig.c.
1542 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1543 argument and did not set the broadcast packet flag. Affected
1544 file silcd/packet_send.c. Fixed same bug in the function
1545 silc_server_send_notify as well.
1547 * If we receive NEW_ID packet for our own ID in the server, ignore
1550 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Removed the nickname from the Private Message Payload.
1555 Updated the code and the protocol specs.
1557 * Updated protocol specs for submitting to the IETF.
1559 * Tweaked the Random Number Generator a bit. Affected file
1560 lib/silccrypt/silcrng.c. Exported a new function
1561 silc_rng_[global]_add_noise which can be used to add more
1564 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Do not parse packets with different timeout when protocol
1567 is active -> may cause problem with rekey. Affected file
1570 * When server receives signoff notify it must not create
1571 new channel key if the client is on any channels since the
1572 sender of the signoff notify will create it.
1574 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Added printing of error messages during SKE protocol from the
1577 failure packet sent by server during SKE. Affected file
1580 * Removed the client's failure_callback handling with timeout
1581 and handle it immediately when received.
1583 * The SKE library returned wrong type in SUCCESS and FAILURE
1584 packets. They must be 32 bit MSB not 16 bit MSB.
1586 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Ok, rewrote the logic of the re-key and now it seems to work.
1589 I tested it on high traffic with frequent re-keys without
1590 problems. Added hmac_receive (and renamed hmac to hmac_send)
1591 in SilcClientConnection in lib/silcclient/client.h and
1592 in SilcIDListData in silcd/idlist.h. Also, removed the
1593 SilcPacketParserContext's cipher and hmac fields as they are
1594 not needed anymore and actually caused some problems when
1595 the ciphers and hmac's changed underneath the packet parser.
1597 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * If re-key protocol is active then process the incoming packets
1600 synchronously since we must assure that icoming packets encrypted
1601 with the old key is processed before the new keys is set to
1602 use. This is true other packets than for REKEY packets.
1603 Affected file silcd/server.c. The same was done to client library
1604 as well, affected file lib/silcclient/client.c.
1606 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Fixed bug in client and server to accept the force send if
1609 the packet is send from silc_[server/client]_packet_process
1610 function. Otherwise the packets are never delivered, oops.
1612 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Disable force sending of packets when REKEY protocol is active.
1615 We must assure that no packet is sent directly when rekey is
1616 performed. All packets must be sent through packet queue.
1617 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1618 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1619 function is silc_[server/client]_packet_send_real to check
1622 * Replaced the SIM paths from example config files to
1623 /usr/local/modules. Also, make install creates now

1638 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * When MAC computation fails the silc_packet_decrypt returned 0
1641 even though it was supposed to return -1. Fixed this. The
1642 affected file is lib/silccore/silcpacket.c.
1644 * Do not replace the config files in /etc/silc (in make install)
1645 if they already exist. Affected file ./Makefile.am.
1647 * Do not send re-key packets immediately but through packet queue.
1648 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1650 * Changed silc_net_check_host_by_sock to return FALSE if the
1651 IP/DNS could not be resolved. Though, it returns the IP address
1652 now even if it could not resolve it (but returns also FALSE).
1653 Affected file lib/silcutil/silcnet.[ch].
1655 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1663 contents of the specified public key file.
1665 * Changed the PKCS api to return the public key length when
1666 setting the public key.
1668 * Fixed a fatal bug in the public and private key file loading.
1669 Affected file lib/silccrypt/silcpkcs.c.
1671 * Execute the packet parsing for client with zero (0) timeout
1672 if the protocol is active. Affected file silcd/server.c.
1674 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Made the key generation options to the silcd program. Added
1677 -C option, equivalent to client's option.
1679 * Added new [ServerKeys] config section to the server. It
1680 configures the server's public and private key.
1682 * Defined generic Public Key Payload into the protocol
1683 specification to send specific type of public keys and
1686 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1687 public key or certificate.
1689 * Implemented the GETKEY command to the server and to the
1690 client library and on user interface.

1694 * Made preliminary `make install' work.
1696 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * Added SilcServerRekey context into silcd/idlist.h.
1700 * Added the PFS support as defined in the specification to the
1701 SKE protocol. Affected files lib/silcske/*.c.
1703 * Added `ske_group' field to the SilcServerRekey context to hold
1704 the number of the SKE group that is used with PFS in re-key.
1705 Affected file silcd/idlist.h.
1707 * Added PFS re-key support to the server. Affected file is
1710 * Added silc_protocol_cancel to cancel execution of the next
1711 state of the protocol. Affected file is
1712 lib/silccore/silcprotocol.[ch].
1714 * Added the re-key support with and without PFS to the client
1715 library. Re-key is performed once in an hour, by default.
1717 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1718 Added silc_client_rekey_callback and silc_client_rekey_final.
1719 Affected files are lib/silcclient/protocol.[ch] and
1720 lib/silcclient/client.[ch].
1722 * Removed the `hmac_key' and `hmac_key_len' fields from the
1723 SilcClientConnection structure; not needed. Affected file is
1724 lib/silcclient/client.h.
1728 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Do not ask whether user wants to use the negotiated private key
1731 for private messages, just use it. Affected file is
1732 silc/local_command.c.
1734 * Added `send_enc_key' and `enc_key_len' fields to the
1735 SilcIDListData structure since they are needed in the re-key
1736 phase. Affected file is silcd/idlist.[ch].
1738 * Implemented the simple re-key protocol into the server.
1739 Affected files silcd/server.c and silcd/protocol.[ch]. The
1740 re-key will be performed once in an hour, by default.
1742 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1743 Added silc_server_rekey, silc_server_rekey_callback and
1744 silc_server_rekey_final.
1746 * Removed Tunneled flag from the protocol. Updated the code
1747 and the specifications.
1749 * Adde `pfs' field to the SilcIDListData to indicate whether
1750 the PFS is to be performed in the re-key. Affected file is
1753 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1756 int64 of at least the xintXX size. If void * is less that 4
1757 bytes uint32 * will be used. Defined bool as boolean.
1759 * Changed _ALL_ unsigned long and unsigned int to uint32,
1760 unsgined short to uint16 in the source tree.
1762 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1763 not handle clients that has entry->data.registered == FALSE.
1764 They are not in the network anymore. Affected file is
1767 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Implemented the sending of the SERVER_SIGNOFF notify in the
1770 server. Affected file is silcd/server.c.
1772 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1773 Added also silc_notify_payload_encode_args into the

1777 Affected file silcd/packet_receive.c.
1779 * Implemented the SERVER_SIGNOFF notify handling in the client
1780 library. Affected file lib/silcclient/client_notify.c. Also,
1781 implemnted the printing of the SERVER_SIGNOFF info to the
1782 application. Affected file silc/client_ops.c.
1784 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1785 if the deleting was successful. Affected file silcd/idlist.[ch].
1787 * Added support for public key authentication in the connection
1788 authentication protocol in the client library. Affected file
1789 lib/silcclient/protocol.c.
1791 * Changed the server's silc_idlist_get_clients_by_* interface
1792 to support already allocated array so that new entries may be
1793 added to pre-allocated array. Affected file silcd/idlist.[ch].
1794 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1795 and command replies.
1797 * All command reply functions in the server now calls the
1798 pending command callback even if error occured. This way the
1799 error will be delivered to the client as well. Affected files
1800 silcd/command.c and silcd/command_reply.c.
1802 * Fixed INFO command to return local server's info if no server
1803 was provided. Affected file lib/silcclient/command.c.
1805 * Removed RESTART command for good. Updated the code and the
1808 * Rewrote parts of the task system. It is a bit simpler now.
1809 Removed unsued task priorities. The affected files are
1810 lib/silcutil/silctask.[ch].
1812 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1814 * Moved the USERS printing from the library to the application.
1815 Affected files lib/silcclient/command.c and silc/client_ops.c.
1817 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Added channel key re-key support. The re-key is perfomed
1822 only by the router and is done once in an hour. Added `rekey'
1823 field to the SilcChannelEntry in the server. Affected files
1824 silcd/server.c and silcd/idlist.h.
1826 * Added silc_task_unregister_by_context into the file
1827 lib/silcutil/silctask.[ch].
1829 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Added SILC_UMODE_GONE mode to indicate when the client is not
1832 present in the SILC network. Added also support to the local
1833 command AWAY that will set this mode. Added support of showing
1834 "xxx is gone" in WHOIS command. The USERS command shows the
1835 gone status as well.
1837 * Fixed setting server and router operator privileges in the
1838 server's UMODE command. Affected file silcd/command.c.
1840 * Merged the SKE KE1 and KE2 payloads into one payload. The
1841 new KE payload is equivalent to the old KE2 payload.
1843 Cleaned up the SKE Start Payload parsing. It now uses the
1844 simple buffer unformatting to do the parsing. A lot faster
1847 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1848 to the SKE that is used to indicate whether both of the SKE
1849 parties should perform authentication. By default only the
1850 responder performs authentication. By setting this flag also
1851 the initiator must do authentication. By default it is unset
1852 since in normal SKE case, client to server connection, only
1853 the responder should do authentication. When doing SKE between
1854 two clients both should perform authentication. Updated the
1855 code and the protocol specs.
1857 * A little fix to IDENTIFY command in the server. Search the
1858 client first by hash not nickname. Affected file is
1861 * Fixed the silc_client_close_connection to support closing
1862 the client to client connections wihtout deleting too much
1863 data. Affected file lib/silcclient/client.c.
1865 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1866 are received if protocol used to be active but is not anymore
1867 the application would crash due to NULL pointer dereference.
1868 Affected files silcd/server.c and lib/silcclient/client.c.
1870 * Added `hash' field to the SilcClientConnection to include
1871 the hash function negotiated in the SKE protocol.
1873 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1874 to set the channel founder authentication data. A client can
1875 claim the founder rights later by providing the authentication
1876 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1877 This way the channel founder can regain the channel founder
1878 privileges even it is left the channel. This works only on
1879 local server and the client must be connected to the same
1880 server to be able to regain the founder rights. Updated the
1881 protocol specs accordingly.
1883 Added support to the CMODE command in the client to set the
1884 founder auth data. Read the README to see how to set it.
1886 Added support to the CUMODE command to claim the founder
1887 rights. Read the README to see how to do it.
1889 Added support for the founder authentication to the Channel
1890 Entry in the server. Affected file silcd/idlist.h.
1892 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1893 server's CMODE command. Affected file silcd/command.c.
1895 * Added the following new functions into lib/silccore/silcauth.[ch]:
1896 silc_auth_get_method and silc_auth_get_data.
1898 * The server now saves the remote hosts public key to the
1899 SilcIDListData pointer. Affected file silcd/protocol.c.
1901 * The normal server now does not remove the channel entry from
1902 the cache if the founder authentication data is set. It used
1903 to remove it if the founder was the last one on the channel on
1904 the server and left the channel. The auth data is saved and
1905 if the channel is re-joined later the old entry is used with
1906 the old auth data. Affected files silcd/command_reply.c and
1909 * Removed the `pkcs' field from the SilcIDListData structure
1910 in the server; it is not used. Affected file silcd/idlist.h.
1912 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Fixed packet processing on slow links. Partial packets were
1915 never re-processed because the incoming data buffer was cleared
1916 by the application. Application must not directly clear the
1917 sock->inbuf, the packet processing routines handle it. Fixed
1918 this in client library and in server.
1920 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Fixed the WHOIS and IDENTIFY send reply function to really
1923 check whether to send list or just one entry. Affected file
1926 * Cleaned up the LEAVE command's channel key distribution. The
1927 affected file silcd/command.c.
1929 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1930 can enforce the channel mode as well. In that case the ID
1931 includes the ID of the server. The code now enforces the
1932 mode change if the router have different mode than the server.
1934 * The notify client operation with CMODE_CHANGE notify can now
1935 return NULL client_entry pointer if the CMODE was not changed
1936 by client. Application must check for this.
1938 * Added <Server ID> argument to INFO command to support server
1939 info fetching by Server ID.
1941 * Added silc_server_announce_get_channel_users to get assembled
1942 packets of channel users of the specified channel. Affected
1943 file silcd/server.[ch].
1945 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1946 was freed underneath the ID Cache.
1948 * Re-announce clients when the server received CHANNEL_CHANGE
1949 notify from the router. Affected file silcd/packet_send.c.
1951 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1954 crashed since it did not handle the fact that there is no cipher
1955 called "3" and didn't check the error condition. Now fixed.
1957 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1958 flag. It can be used to send message requests.
1960 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Implemented the RESTART command in the client.
1964 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1965 notice type messages. Added notice printing to the user
1968 * The channel keys are not re-generated if the channel's mode
1969 is PRIVKEY, ie private key on the channel exists. Affected
1970 files silcd/server.c and silcd/command.c.
1972 * Fixed a little bug in channel message delivery when channel
1973 private keys are set in the server. Affected file is
1974 silcd/packet_send.c.
1976 * Changed the setting on channel->on_channel = TRUE from the
1977 silc_client_save_channel_key to the JOIN command reply. The
1978 key payload is not received if the private channel key is set.
1979 Affected file lib/silcclient/command_reply.c and the
1980 lib/silcclient/client_channel.c.
1982 * When the CMODE_CHANGE notify is sent and the channel private
1983 key mode is removed the channel key must be re-generated in
1984 other cells as well. Added this support for the router in the
1985 silcd/packet_receive.c.
1987 * Added new local command NOTICE to send notice message on
1988 channel. Affected file silc/local_command.[ch].
1990 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Added new local command ME to the client. It is used to send
1993 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1994 some action. Affected file silc/local_command.[ch].
1996 * Changed channel_message and private_message client operations
1997 to deliver the message flags to the application. Added also
1998 the `flags' arguments to the silc_client_send_channel_message
1999 and silc_client_send_private_message functions. Affected file
2002 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2004 * Redefined the Private Message Payload to support private message
2005 keys and to support the new private message flags. Updated
2006 the protocol specs. Flags makes it possible to have for example
2007 CTCP style messages.
2009 * Added new type SilcPrivateMessagePayload and defined an API
2010 for it in the lib/silcclient/silcprivate.[ch].
2012 * Tested private message private keys successfully. Tested the
2013 private message key set, unset and list commands with the new
2016 * Redefined the Channel Message Payload to include the channel
2017 message flags (equal with private message flags) to support
2018 for example CTCP style messages.
2020 * Defined some of the message (for channel and private message)
2021 flags. Updated the protocol specs and added the flags to the
2022 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2024 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Added SilcKeyAgreementStatus type to the key agreement routines
2027 to indicate the current status and error if one occured.
2028 The status types are defined in the lib/silcclient/silcapi.h.
2030 * Added new local command KEY that is used to set and unset private
2031 keys for channels, set and unset private keys for private messages
2032 with remote clients and to send key agreement requests and
2033 negotiate the key agreement protocol with remote client. The
2034 key agreement is supported only to negotiate private message keys,
2035 it currently cannot be used to negotiate private keys for channels,
2036 as it is not convenient for that purpose.
2038 * Fixed a minor pending callback setting bug in the function
2039 silc_client_get_client_by_id_resolve, now the function works.
2040 Affected file lib/silcclient/idlist.c.
2042 * Added function silc_net_get_local_port to get local bound
2043 port by socket. Added to lib/silcutil/silcnet.[ch].
2045 * Added `sockets' and `sockets_count' fields to the SilcClient
2046 object. They hold the sockets of the listenning sockets in
2047 the client. Listenning sockets may be for example the key
2048 agreement server. Affected file lib/silcclient/client.[ch].
2049 Added functions the silc_client_add_socket and the
2050 silc_client_del_socket. They are exported to the application
2053 * Added ~./silc/clientkeys to support other client's public keys.
2055 * Renamed verify_server_key client operation to verify_public_key
2056 and added one argument to indicate the type of the connection
2057 (server, client etc.).
2059 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Added silc_server_connection_auth_request to handle the
2062 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2063 silcd/packet_receive.[ch].
2065 * Added silc_server_send_connection_auth_request into the
2066 silcd/packet_send.c to send the connection auth request packet.
2068 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2071 * Fixed the public key authentication in responder side in the
2072 server. The `auth_data' pointer includes the SilcPublicKey
2073 not the path to the public key. Affected file silcd/protocol.c.
2075 * Implemented the public key authentication in the initiator side
2076 in the server. Affected file silcd/protocol.c.
2078 * Removed the [RedirectClient] config section from the server
2079 configuration. Is not needed and I don't want to implement it.
2081 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Cleaned up the CMODE command in the server. It now works
2084 correctly and supports all the modes defined in the protocol.
2085 Affected file is silcd/command.c.
2087 * Added `hmac_name' field to the SilcChannelEntry in the server
2088 to hold the default HMAC of the channel. It can be set when
2089 creating the channel (with JOIN command). Affected files
2092 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2093 type to indicate the change of the current cipher and hmac
2094 on the channel. Client can safely ignore the <cipher> argument
2095 (if it chooses to do so) since the CHANNEL_KEY packet will
2096 force the channel key change anyway. The <hmac> argument is
2097 important since the client is responsible of setting the new
2098 HMAC and the hmac key into use.
2100 * Fixed the CMODE command in the client library as well.
2102 * Tested CMODE command in router environment successfully.
2104 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Show the version of the remote client (or server) when connecting
2107 to the server. It is logged to the log file. Affected file
2108 is silcd/protocol.c.
2110 * Fixed the KILLED notify handling in the client library. The
2111 client must be removed from all channels when receiving the
2114 Also, do not remove the client entry when giving the KILL
2115 command but when the KILLED notify is received.
2117 * Removed silc_idlist_find_client_by_nickname from the server.
2118 Not needed anymore. Affected files silcd/idlist.[ch].
2120 * Implemented the CHANNEL_CHANGE notify type handling to the
2121 server. Affected file silcd/server.c.
2125 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Added silc_server_send_notify_invite to send the INVITE
2128 notify between routers.
2130 * Implemented the INVITE command correctly to the server.
2132 * Implemented the INVITE notify type handling in the server.
2134 * Implemented the INVITE command to the client library and on the
2137 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Added function silc_server_get_client_resolve to find the
2140 client entry by ID from all ID lists and then resolve it
2141 (using WHOIS) if it cannot be found. Affected file is
2144 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Implemented the BAN command to the client library.
2148 * The JOIN command in the server now checks the invite list
2151 * Changed the silc_command_reply_payload_encode_va and the
2152 silc_command_payload_encode_va to support that if argument is
2153 NULL it ignores and checks the next argument. Affected file
2154 lib/silccore/silccommand.c.
2156 * Added silc_server_send_notify_ban to send the BAN notify
2157 type between routers.
2159 * Chaned the silc_notify_payload_encode to support that if
2160 argument is NULL it ignores and checks the next argument.
2161 Affected file lib/silccore/silcnotify.c.
2163 * Tested ban lists in router environment successfully.
2165 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Implemented BAN command to the server, in silcd/command.[ch].
2169 * Removed the BAN and INVITE_LIST modes from the CMODE command
2172 * Added function silc_string_match to regex match two strings.
2173 Affected files lib/silcutil/silcutil.[ch].
2175 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Redefined parts of the SilcChannelEntry in the server to support
2178 the new ban and invite lists.
2180 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * Redefined the INVITE command. The same command can be used to
2183 invite individuals to the channel but also to manage the invite
2184 list of the channel (to add to and remove from the invite list).
2185 Updated the protocol specs.
2187 * Added new command SILC_COMMAND_BAN that can be used to manage
2188 the ban list of the channel. Updated the protocol specs.
2190 * Removed the channel modes: the SILC_CMODE_BAN and the
2191 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2192 in the CMODE command. The equivalent features are now available
2193 using INVITE and BAN commands. Updated the protocol specs.
2195 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2196 in the network about change in the current ban list. The notify
2197 type is not used by the client.
2199 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2200 support the invite lists.
2202 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Added new function silc_string_regexify that converts string
2205 including wildcard characters into regex string that can
2206 be used by the GNU regex library. Added into the file
2207 lib/silcutil/silcutil.[ch].
2209 Added silc_string_regex_combine to combine to regex strings
2210 into one so that they can be used as one regex string by
2211 the GNU regex library. Added into the file
2212 lib/silcutil/silcutil.[ch].
2214 Added silc_string_regex_match to match two strings. It returns
2215 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2217 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Imported GNU regex to the soruce tree into lib/contrib.
2220 Fixed some compiler warning from the regex.c.
2222 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Fixed MOTD command in the server to work in router environment.
2226 * Fixed the MOTD command in the client library to support
2227 the server argument in the command.
2229 * Added `nickname_len' argument to the silc_idlist_add_client
2230 in the server, as the `nickname' argument may be binary data
2233 * Added silc_idlist_get_channels to return all channels from
2236 * Implemented LIST command to the server. Affected file is
2239 * Implemented the LIST command to the client library and on the
2242 * Added [<user count>] argument to the LIST command reply.
2243 With private channels the user count is not shown.
2245 * Updated TODO and README.
2247 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * The client entry's data.registered must be TRUE even with
2250 global client entry on global client list. The data.registered
2251 is used to check whether the client is anymore in the network,
2252 for example with WHOWAS command so it must be valid.
2254 * Fixed the WHOWAS command in the server. It now actually works
2255 in router environment. Added function into silcd/command_reply.c
2256 silc_server_command_reply_whowas_save.
2258 * Added silc_idlist_purge function to the silcd/idlist.c
2259 to periodically purge the ID Cache.
2261 * Fixed INFO command in the server. It works now in router
2262 environment. Added <server name> argument to the INFO command
2263 reply. Updated the protocol specs.
2265 * Fixed minor bug in silc_idcache_purge to not purge if the
2266 expire value is zero.
2268 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2269 they were buggy because of the WHOWAS information.
2271 * Fixed local command MSG to handle the async resolving of
2272 the remote client properly. It used to fail the first MSG.
2273 Affected file silc/local_command.c.
2275 * Added `data_len' field to SilcIDCache context.
2277 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Update TODO. Todo in commands in the server.
2281 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2284 used by routers as broadcast packet to inform other routers
2285 about the changed user mode.
2287 Implemented the notify handling in the server. Affected file is
2288 silcd/packet_receive.c. Added the function
2289 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2291 * Added new generic Channel Payload and deprecated the New Channel
2292 Payload. The New Channel Payload is now the generic Channel
2295 * Added new argument `mode' to the silc_server_send_new_channel
2296 as it is required in the Channel Payload now.
2298 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2299 and created a new and real SilChannelPayload to represent the
2300 new generic Channel Payload. Implemented the encode/decode
2301 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2303 * Added silc_server_get_client_channel_list to return the list
2304 of channels the client has joined for WHOIS command reply.
2305 Affected file silcd/server.[ch].
2307 * Implemented the channel list sending in the WHOIS command reply
2308 in server and in the client.
2310 Implemented the channel list displaying on the user interface
2311 as well. Affected file silc/client_ops.c.
2313 * Added silc_channel_payload_parse_list to parse list of Channel
2314 Payloads. It returns SilcDList list of SilcChannelPayloads.
2315 Client for example can use this function to parse the list of
2316 channels it receives in the WHOIS command reply. The caller
2317 must free the list by calling silc_channel_payload_list_free.
2318 Affected files lib/silccore/silcchannel.[ch].
2320 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2322 * Added one new argument <user mode> to the WHOIS command reply
2323 to return the mode of the user in SILC. Updated the protocol
2326 Implemented it to the server and client.
2328 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Fixed the mode printing on the user interface on joining.
2331 Affected file silc/client_ops.c.
2333 * Implemented the UMODE command and user modes in general to the
2334 client library and to the user interface.
2336 * Implemented the UMODE command to the server.
2338 * The server now sends UNKNOWN_COMMAND error status if client sends
2339 unknown command. Affected file silcd/command.c.
2341 * All server commands now handle the command identifier the right
2342 way when sending the command reply to the client. The client can
2343 use to identify the command replies with the identifier.
2345 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Added silc_server_get_client_route to resolve the route to
2348 the client indicated by the client ID. Affected file is
2351 * Added silc_server_relay_packet as general function to relay
2352 packet to arbitrary destination. This deprecates functions
2353 like _send_private_message_key, _relay_notify etc. Affected
2354 file is silcd/packet_send.[ch].
2356 Removed silc_server_send_key_agreement,
2357 silc_server_send_private_message_key and
2358 silc_server_packet_relay_notify functions from the file
2359 silcd/packet_send.[ch].
2363 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2364 server. Affected file silcd/packet_receive.[ch].
2366 * Implemented the KILL command to the client. Implemented the
2367 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2368 Affected files lib/silcclient/command[_reply].c and
2369 lib/silcclient/client_notify.c. Implemented the KILL notify
2370 printing in the user inteface.
2372 * Fixed a lot silc_parse_nick memory leaks from the client
2373 library in the file lib/silcclient/command.c.
2375 * Changed the silc_server_send_notify_on_channels's `sender'
2376 argument from SilcSocketConnection to SilcClientEntry to
2377 check the sender as entry and not as connection object and not
2378 to send to the client provided as argument. The affected file
2379 is silcd/packet_send.[ch].
2381 * The notify packets that are destined directly to the client used
2382 to not to be processed by the server. Now changed that and the
2383 server processes all notify packets. After relaying the packet
2384 to the client the notify packet is processed in the server.
2386 * The silc_server_free_client_data now checks whether there is
2387 pending outgoing traffic for the client and purges the data to
2388 the network before removing the client entry.
2390 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2393 an client is killed from the SILC Network. Updated the protocol
2396 Added new function silc_server_send_notify_killed to the
2397 silcd/packet_send.[ch].
2399 * Added function silc_server_packet_relay_notify to relay notify
2400 packets that are destined directly to a client. In this case
2401 the server does not process the notify packets but merely relays
2402 it to the client. Affected file silcd/packet_send.[ch].
2404 Added also silc_server_packet_process_relay_notify to check
2405 whereto relay the notify. Affected file is
2406 silcd/packet_receive.[ch].
2408 * Implemented the KILL command to the server.
2412 * Added the backup schema desgined last fall to the protocol
2413 specs for everyone to see. The specification is in the
2414 *-spec-xx.txt draft and the packet type definitions for the
2415 backup routers is in *-pp-xx.txt draft. Thusly, added also
2416 new packet type SILC_PACKET_CELL_ROUTERS.
2418 * A big security problem in the implementation discovered. The
2419 signoff of an client did not cause new channel key generation
2420 which it of course should've done. The channel keys must be
2421 always re-generated when client leaves (or signoffs) the channel.
2422 The silc_server_remove_from_channels funtion now handles
2423 the channel key re-generation.
2425 * Added `sender' argument to the silc_server_send_notify_on_channels
2426 to not to send the client provided as argument. Affected file
2427 silcd/packet_send.[ch].
2429 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Implemented OPER and SILCOPER commands into the server and
2434 * Added silc_auth_verify and silc_auth_verify_data to verify
2435 the authentication directly from the authentication payload.
2436 It supports verifying both passphrase and public key based
2437 authentication. Affected file lib/silccore/silcauth.[ch].
2439 * Added `hash' field to the SilcIDListData structure. It is the
2440 hash negotiated in the SKE protocol. Affected file is
2443 * Slight redesigning of the SilcAuthPayload handling routines.
2444 Do not send SilcPKCS but SilcPublicKey as argument.
2446 * Implemented the public key authentication support to the
2447 serverconfig. The public key is loaded from the provided path
2448 and saved as authentication data to void * pointer. Thus,
2449 changed the unsigned char *auth_data to void *auth_data;
2451 * Fixed SHUTDOWN command to send the reply before the server
2452 is shutdown. :) Affected file silcd/command.c.
2454 * Fixed fatal bug in CONNECT command. The hostname was invalid
2455 memory and server crashed. Affected file silcd/command.c.
2457 * Fixed fatal bug in CLOSE command. The server_entry became
2458 invalid but was referenced later in the command. Affected file
2461 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2463 * Fixed fatal bug in failure packet handling. Server ignored
2464 the failure and thus crashed when it came.
2468 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2471 that the command may be executed only once in (about) 2 seconds.
2472 The old SILC_CF_LAG flag is same but allows command bursts up
2473 to five before limiting.
2475 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2476 server code. Various commands now includes the CF_LAG_STRICT
2477 flag to disallow any kind of miss-use of the command.
2479 * Fixed the silc_buffer_unformat to not to allocate any data
2480 if the length of the data is zero. It used to allocate the
2481 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2483 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Changed the format of AdminConnection configuration section
2486 in the server. Added username of the admin to the format.
2487 Affected files silcd/serverconfig.[ch].
2489 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2490 to return admin configuration data by host, username and/or
2493 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * Implemented WHOWAS command to the server. Added the functions:
2497 silc_server_command_whowas_parse,
2498 silc_server_command_whowas_send_reply,
2499 silc_server_command_whowas_from_client and
2500 silc_server_command_whowas_from_server
2502 * Added <Client ID> argument to the WHOWAS command reply. Updated
2503 the protocol specs accordingly.
2505 * Implemented WHOWAS command and command_reply to the client
2508 Implemented the WHOWAS printing on the user interface.
2510 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2512 * Added new argument to the WHOWAS command reply, the real name.
2513 It is an optional argument. Updated the protocol specs.
2515 * Added SilcIDCacheDestructor callback that is registered when
2516 the SilcIDCache is allocated. The callback is called when
2517 an cache entry in the ID Cache expires, or is purged from the
2518 cache. Added into lib/silccore/idcache.[ch].
2520 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2521 to destruct the client entries when the cache entry expires.
2522 Other ID Cache's in server and in the client library ignores
2525 * If the ID Cache entry's `expire' field is zero then the entry
2526 never expires. Added boolean `expire' argument to the
2527 silc_idcache_add function in the lib/silccore/idcache.[ch].
2528 If it is TRUE the default expiry value is used.
2530 * Added silc_server_free_client_data_timeout that is registered
2531 when client disconnects. By default for 5 minutes we preserve
2532 the client entry for history - for WHOWAS command.
2534 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Added support to the server to enforce that commands are not
2537 executed more than once in 2 seconds. If server receives
2538 commands from client more frequently, timeout is registered
2539 to process the commands. Affected file silcd/command.c.
2540 Added new function silc_server_command_process_timeout.
2542 * Changed NICK_NOTIFY handling in client library to check that
2543 if the client's nickname was changed, so there is no need to
2544 resolve anything from the server.
2546 * Removed error printing from the WHOIS and IDENTIFY commands.
2547 If error occurs then it is ignored silently in the client library.
2548 The application, however, may map the received error to
2549 human readable error string. The application currently maps
2550 the NO_SUCH_NICKNAME error to string.
2552 * Made the command status message public to the application. Moved
2553 them from lib/silcclient/command_reply.c to
2554 lib/silcclient/command_reply.h. The application can map the
2555 received command status to the string with the
2556 silc_client_command_status_message function.
2558 * Added check to the server to check that client's ID is same
2559 as the Source ID in the packet the client sent. They must
2562 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Added dist-bzip hook to the Makefile.am to make bzip2
2565 compressed distributions.
2567 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Server now enforces the maximum length for the nickname and
2570 the channel as protocol specification dictates. 128 bytes for
2571 nickname and 256 bytes for channel name.
2573 * Moved the WHOIS printing to the application. The client libary
2574 does not print out the WHOIS information anymore, the application
2575 must do it. Renamed silc_client_command_reply_whois_print to
2576 the silc_client_command_reply_whois_save.
2578 The client's idle time is also sent to the application now, and
2579 the idle is shown on screen.
2581 * Added silc_client_command_reply_identify_save to save the
2582 received IDENTIFY entries.
2584 * Do not check for channel private keys in message sending and
2585 reception if the channel does not have the PRIVKEY mode set.
2586 Affected file lib/silclient/client_channel.c.
2588 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2591 just surfaced after chaning the JOIN procedure.
2593 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added silc_client_get_clients_by_list to get client entries
2596 from Client ID list, that is returned for example by JOIN
2597 and USERS command replies. The application should use this
2598 function for example when JOIN command reply is received to
2599 resolve the clients already on the channel (library does not
2600 do that anymore as USERS command reply is not used in the JOIN
2601 procedure anymore). Affected files lib/silcclient/silcapi.h and
2602 lib/silcclient/idlist.c.
2604 * JOIN command reply and USERS command reply returns now SilcBuffer
2605 pointers instead of unsigned char pointers when returning
2606 the client list and mode list.
2608 * Added <Client ID> argument to the JOIN command reply, mainly
2609 for the server to identify for which client the command was
2610 originally sent. Updated protocol specs accordingly.
2612 * Added SilcDlist private_key pointer to the SilcChannelEntry
2613 in the client to support the channel private keys. Affected
2614 file is lib/silcclient/idlist.h.
2616 * Added SilcChannelPrivateKey argument to the function
2617 silc_client_send_channel_message so that application can choose
2618 to use specific private ke if it wants to. If it is not provided,
2619 the normal channel key is used, unless private keys are set.
2620 In this case the first (key that was added first) is used
2621 as the encryption key.
2623 * Implemented the support for channel private key handling.
2624 Implemented the following functions:
2626 silc_client_add_channel_private_key,
2627 silc_client_del_channel_private_keys,
2628 silc_client_del_channel_private_key,
2629 silc_client_list_channel_private_keys and
2630 silc_client_free_channel_private_keys
2632 Affected file lib/silcclient/client_channel.c.
2634 * Added the support for the private keys in the channel message
2635 sending and encryption and in the message reception and
2636 decryption. Affected funtions are
2637 silc_client_send_channel_message and silc_client_channel_message.
2639 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Added SKE's key verify callback to the client library's
2642 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2644 * Removed the statement that server (or router) must send USERS
2645 command reply when joining to the channel so that the client
2646 knows who are on the channel. Instead, the client list and
2647 client's mode list is now sent in the JOIN command reply to the
2648 client who joined channel. This is better solution.
2650 * Added function silc_server_get_users_on_channel and function
2651 silc_server_save_users_on_channel to the silcd/server.[ch].
2653 * Removed function silc_server_command_send_users from the
2656 * Do not show topic on the client library anymore. The topic is
2657 sent in the command reply notify to the application and the
2658 application must show the topic now.
2660 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2662 * Added client searching by nickname hash into the IDENTIFY and
2663 WHOIS commands in the server as they were clearly missing from
2664 them. Affected file is silcd/command.c.
2666 * Fixed a bug in private message receiving in the client library.
2667 The remote ID was freed and it wasn't supposed, now it is
2670 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Minor fix to the channel payload; allocate the data area, as it
2673 needs to be of specific length.
2675 * If the key agreement port is zero then the operating
2676 system will define the bound port. Affected files are
2677 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2679 * Added new function silc_channel_payload_decrypt into the file
2680 lib/silccore/silcchannel.[ch].
2682 * Moved the channel message etc, check from silc_packet_decrypt
2683 to applications. The library calls now a generic
2684 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2685 when the packet is either normal or special. This was done to
2686 allow more wide range of checking that was not allowed when
2687 the code was in library. Now applications can do virtually any
2688 checks to the packet and return to the library the decision how
2689 the packet should be processed. Affected files are
2690 lib/silccore/silcpacket.[ch].
2692 Added silc_server_packet_decrypt_check to the server and
2693 silc_client_packet_decrypt_check to the client library.
2695 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2696 to send with specified source and destination information.
2698 * Channel message delivery between routers was broken after the
2699 channel key distribution was fixed earlier. The channel key
2700 was used be to distributed to other routers as well which is not
2701 allowed by the protocol. Now this is fixed and channel keys
2702 really are cell specific and the channel message delivery between
2703 routers comply with the protocol specification.
2705 * Fixed various commands in server to check also the global list
2706 for the channel entry and not just the local list. The affected
2707 file silcd/command.c.
2709 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Added assert()s to buffer formatting and unformatting routines
2712 to assert (if --enable-debug) when error occurs. Affected
2713 file: lib/silcutil/silcbuffmt.c.
2715 * Changed to auto-reconnect to check whether the remote host is
2716 router and register the re-connect timeout if it is. It used
2717 to check that whether we are normal server, but router must do
2718 auto-reconnect with another router as well. Affected file
2721 * Removed the [<key len>] option from CMODE command as the cipher
2722 name decides the key length, nowadays. See the defined ciphers
2723 from the protocol specification.
2725 * Added [<hmac>] option to the CMODE command to define the HMAC
2726 for the channel. Added SILC_CMODE_HMAC channel mode.
2728 * Added [<hmac>] option for the JOIN command so that user can
2729 select which HMAC is used to compute the MACs of the channel
2732 * Added Hmac field to the Channel Message Payload. The integrity
2733 of plaintext channel messages are now protected by computing
2734 MAC of the message and attaching the MAC to the payload. The
2735 MAC is encrypted. Now, it is clear that this causes some
2736 overhead to the size of the packet but rationale for this is that
2737 now the receiver can verify whether the channel message decrypted
2738 correctly and also when private keys are set for the channel the
2739 receiver can decrypt the packet with several keys and check from
2740 the MAC which key decrypted the message correctly.
2742 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2743 lib/silccrypt/silccipher.[ch].
2745 * Added silc_hash_len to return the digest length into the
2746 lib/silcrypt/silchash.[ch].
2748 * Rewrote parts of Silc Channel Payload interface in the
2749 lib/silccore/silcchannel.[ch]. The encode function now also
2750 encrypts the packet and parse function decrypts it.
2752 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Fixed a minor formatting bug in the SKE's key material processing.
2755 It actually might have processed the keys wrong way resulting
2758 * Redefined the mandatory HMAC algorithms and added new algorithms.
2759 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2760 and hmac-md5 truncated to 96 bits. The mandatory is now
2761 hmac-sha1-96. Rest are optional (including the one that used
2762 to be mandatory). Rationale for this is that the truncated HMAC
2763 length is sufficient from security point of view and can actually
2764 make the attack against the HMAC harder. Also, the truncated
2765 HMAC causes less overhead to the packets. See the RFC2104 for
2768 * Added new [hmac] configuration section. The SKE used to use
2769 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2770 is of course wrong. The official names that must be proposed in
2771 the SKE are the ones defined in the protocol specification
2772 (hmac-sha1-96 for example). The user can configure any hmac
2773 using any hash function configured in the [hash] section. At
2774 least, the mandatory must be configured.
2776 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2778 * Added HMAC list to the SKE proposal list. It has now both
2779 hash algorithm list and HMAC list. This makes the protocol
2780 incompatible with previous versions. The SKE now seems to work
2781 the way it is supposed to work, for the first time actually.
2783 * Defined plain Hash algorithms to the protocol specification.
2786 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Implemented support for key agreement packets into the server.
2789 Added functions silc_server_key_agreement and
2790 silc_server_send_key_agreement. Other than these functions,
2791 server has nothing to do with this packet.
2793 * Added support for private message key packets into the server.
2794 Added functions silc_server_private_message_key and
2795 silc_server_send_private_message_key.
2799 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2800 called in the protocol's final callback instead in the END
2801 protocol state. This makes a little more sense and in the same
2802 time in client we can use the same protocol routines for normal
2803 key exchange and to key agreement packet handling as well.
2805 * Added to both client's and server's KE protocol context the
2806 SilcSKEKeyMaterial pointer to save the key material. We will
2807 bring the key material to the protocol's final callback by doing
2808 this. The final callback must free the key material.
2810 * Added SKE's packet_send callback into client's KE protocol
2811 context so that the caller can choose what packet sending function
2812 is used. This way we can use different packet sending when
2813 doing normal SKE when doing key agreement packet handling (in
2814 the key agreement packet handling we do not want to encrypt
2817 * Implemented the responder side of the key agreement routines
2818 in the client. The client can now bind to specified port and
2819 accept incoming key negotiation. The key material is passed
2820 to the application after the protocol is over.
2822 * Implemented the processing of incoming Key Agreement packet
2823 in the client. Added function silc_client_key_agreement to
2826 * Implemented the intiator side of the key agreement routines
2827 in the client. The client can now initiate key agreement with
2828 another remote client. The key material is passed to the
2829 application after the protocol is over.
2831 * Created client_keyagr.c to include all the key agreement
2834 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2835 SILC_TASK_CALLBACK except that it is not static.
2837 * Created client_notify.c and moved the Notify packet handling
2838 from the client.[ch] into that file.
2840 * Created client_prvmsg.c and moved all private message and
2841 private message key routines from the client.[ch] into that file.
2843 * Create client_channel.c and moved all channel message and
2844 channel private key routines from the client.[ch] into that file.
2846 * Changed silc_client_get_client_by_id_resolve to resolve with
2847 WHOIS command instead of IDENTIFY command, in the file
2848 lib/silclient/idlist.c.
2850 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Implemented the SKE's responder side to the Client library.
2854 * When FAILURE is received to the protocol do not trust it
2855 blindly. Register a timeout to wait whether the remote closes
2856 the connection as it should do it, only after that process the
2857 actual failure. This was changed to both client and server.
2859 * Added client_internal.h to include some of the structures
2860 there instead of client.h in lib/silcclient/.
2862 * Added function silc_task_unregister_by_callback to unregister
2863 timeouts by the callback function.
2865 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Some "Incomplete WHOIS info" errors has been appearing on the
2868 log files. Took away the entry->userinfo check from WHOIS
2869 reply sending. The entry->userinfo is now " " if client did not
2870 provide one. I thought this was fixed earlier but something
2871 is wrong still. Let's see if the error still appears.
2873 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Fixed a minor bug in the login when the channel key is
2876 re-generated in the server. It used to generate the key in
2877 wrong order and thus caused problems in the channel traffic.
2879 * Fixed a minor bug in channel key distsribution after
2880 KICK command. The key was not sent to the router even though
2883 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * Added silc_ske_process_key_material_data as generic routine
2886 to process any key material as the SILC protocol dictates. The
2887 function is used by the actual SKE library but can be used by
2888 applications as well. This relates to the private message keys
2889 and the channel private keys since they must be processed the
2890 same way the normal SILC session keys. The protocol dictates
2891 this. Affected files: lib/silcske/silcske.[ch].
2893 Added also silc_ske_free_key_material to free the
2894 SilcSKEKeyMaterial structure.
2896 * Defined silc_cipher_set_key function to set the key for
2897 cipher without using the object's method function. The affected
2898 files: lib/silccrypt/silccipher.[ch].
2900 * Implemented silc silc_client_add_private_message_key,
2901 silc_client_add_private_message_key_ske,
2902 silc_client_del_private_message_key,
2903 silc_client_list_private_message_keys and
2904 silc_client_free_private_message_keys functions in the
2907 Added functions silc_client_send_private_message_key to send
2908 the Private Message Key payload and silc_client_private_message_key
2909 to handle incoming Private Message Key payload.
2911 * Added Cipher field to the Private Message Key payload to set
2912 the cipher to be used. If ignored, the default cipher defined
2913 in the SILC protocol (aes-256-cbc) is used.
2915 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Removed lib/silcclient/ops.h file.
2919 Redefined parts of the SILC Client Library API. Created new
2920 file silcapi.h that deprecates the ops.h file and defines the
2921 published Client Library API. Defined also private message key
2922 API and channel private key API into the file.
2924 This is the file that the application must include from the
2925 SILC Client Library. Other files need not be included by
2926 the application anymore.
2928 * Added new key_agreement client operation callback and also
2929 defined the Key Agreement library API for the application.
2931 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2934 is used by clients to request key negotiation between another
2935 client in the SILC network. If the negotiation is started it
2936 is performed using the SKE protocol. The result of the
2937 negotiation, the secret key material, can be used for example
2938 as private message key.
2940 Implemented the Key Agreement payload into the files
2941 lib/silccore/silauth.[ch].
2943 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Redefined ciphers for the SILC protocol. Added some new ciphers
2946 and defined the key lengths for the algorithms. Changed the
2947 code accordingly. The default key length is now 256 bits.
2949 * Fixed SKE key distribution function silc_ske_process_key_material
2950 when the key length is more than 128 bits. The default key
2951 length in SILC is now 256 bits.
2953 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2954 to indicate unsupported algorithm.
2956 * Renamed rijndael.c to aes.c and all functions as well.
2958 * Fixed a long standing channel key setting bug in client library.
2959 Weird that it has never surfaced before.
2961 * Fixed bug in channel deletion. If the entire channel is removed
2962 then it must also delete the references of the channel entry
2963 from the client's channel list as the client's channel entry and
2964 the channel's client entry share same memory.
2966 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Implemented CONNECT and SHUTDOWN commands in the client.
2970 * Implemented CLOSE command to the client.
2972 * Added the function silc_idlist_find_server_by_name into the
2973 files silcd/idlist.[ch].
2975 Added the function silc_idlist_find_server_by_conn into the
2976 files silcd/idlist.[ch].
2978 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * DIE command was renamed to SHUTDOWN. Updated the both code
2983 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2984 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2986 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2989 * Added function silc_server_create_connection function to create
2990 connection to remote router. My server implementation actually
2991 does not allow router to connect to normal server (it expects
2992 that normal server always initiates the connection to the router)
2993 so the CONNECT command is only good for connecting to another
2996 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2999 or some other client was kicked from the channel.
3001 Implemented the handling of the notify type to both client
3004 Implemented silc_server_send_notify_kicked to send the KICKED
3005 notify. It is used to send it to the server's primary router.
3007 * Implemented the KICK command into server and client.
3009 * Added `query' argument to the silc_idlist_get_client function
3010 to indicate whether to query the client from server or not if
3013 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3014 to indicate that the client is not channel founder.
3018 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3020 * Removed the rng context from SilcPacketContext structure and
3021 changed that the packet routine uses the Global RNG API.
3023 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Added support for quit message that client can "leave" on the
3026 channel when it quits the SILC. It is ditributed inside the
3027 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3029 Added silc_server_free_client_data that will take the
3030 signoff message as argument.
3032 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3034 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Updated parts of the protocol specification to keep it up
3039 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3042 payloads in one packet.
3044 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3045 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3046 use now the new List flag.
3048 * Also deprecated the following packet types: REPLACE_ID,
3049 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3051 * Added list support for Notify packet in server.
3053 * Added silc_server_send_notify_channel_change to send the
3054 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3055 the silc_server_send_replace_id.
3057 * Added silc_server_send_notify_nick_change to send the
3058 NICK_CHANGE notify type. Deprecates the function
3059 silc_server_send_replace_id.
3061 * Added silc_server_send_notify_join to send the JOIN notify type.
3062 Deprecates the function silc_server_send_new_channel_user.
3064 * Added silc_server_send_notify_leave to send LEAVE notify type.
3065 Deprecates the function silc_server_send_remove_channel_user.
3067 * Added silc_server_send_notify_cmode and
3068 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3069 types. Deprecates the silc_server_send_set_mode function.
3071 * Added SERVER_SIGNOFF notify type to indicate that server has
3072 quit. This means that all clients on the channel from that
3073 server will drop. This can be also used when netsplit happens.
3075 Deprecated REMOVE_ID packet type since it is not needed anymore
3078 Added silc_server_send_notify_server_signoff to send the
3079 SERVER_SIGNOFF notify type. Deprecates the function
3080 silc_server_send_remove_id.
3082 Added also silc_server_send_notify_signoff to send the
3083 SIGNOFF notify type.
3085 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3086 SILC protocol from this day on. Changed the protocol
3087 specification as well.
3089 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3090 notify type. It is used between routers to notify about
3091 topic changes on a channel.
3093 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3096 * Partly updated the protocol specification to comply with the
3097 changes now made. It is still though a bit outdated.
3099 * The JOIN notify type now takes one extra argument <Channel ID>.
3100 The packet used to be destined to the channel but now the
3101 JOIN type may be sent as list thus it is impossible to
3102 destine it to any specific channel. By adding this argument
3103 it is again possible.
3105 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Added CREDITS file. The CHANGES and CREDITS file will appear
3108 in the distribution as well.
3110 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3113 types in the server's silcd/packet_receive.c.
3115 * Implemented CMODE and CUMODE to work in router environment.
3117 * Fixed minor encoding and decoding buglet from the
3118 lib/silccore/silcmode.c.
3120 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3123 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3125 * Changed all SilcConfigServer* and silc_config_server* to
3126 SilcServerConfig* and silc_server_config*, respectively.
3129 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Associated the ID (client or server ID) to the Authentication
3132 Payload to avoid any possibility of forging. Updated the
3133 protocol specification and the code accordingly.
3135 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * The RSA key length is now save to the RsaKey context in the
3138 key generation process in lib/silccrypt/rsa.c. The key length
3139 is now used to figure out the maximum size of the block allowed
3140 to be encrypted/signed.
3142 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3143 is equivalent to the silc_mp_mp2bin but does not allocate any
3146 * Changed silc_mp_mp2bin API to take length argument. If it is
3147 non-zero then the buffer is allocated that large. If zero, then
3148 the size is approximated using silc_mp_sizeinbase, which however
3151 * Created Global RNG API which is global RNG that application can
3152 initialize. After initializing, any routine anywhere in the
3153 code (including library) can use RNG without allocating a new
3154 RNG object. This was done to allow this sort of use of the
3155 RNG in code that has no chance to allocate RNG object. All
3156 applications currently allocate this and many routines in the
3157 library use this. Affected file lib/silccrypt/silcrng.[ch].
3159 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3160 it to use the Global RNG API.
3162 * Defined Authentication Payload into protocol specification that
3163 is used during SILC session to authenticate entities. It is
3164 used for example by client to authenticate itself to the server
3165 to obtain server operator privileges.
3167 Implemented this payload into the lib/silccore/silcauth.[ch].
3168 Implemented also routines for public key based authentication
3169 as the new protocol specification dictates.
3171 Moved definitions of different authentication methods from
3172 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3174 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3175 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3176 silc_pkcs_verify_with_hash functions into the file
3177 lib/silccrypt/silcpkcs.[ch].
3179 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * The client entry's userinfo pointer must be always valid.
3182 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3183 will fail since it requires the userinfo. Now, the userinfo
3184 is allocated as "" if actual userinfo does not exist. Actually,
3185 it must exist and it is totally Ok to drop client connections
3186 that does not announce the userinfo. However, we will make
3187 this workaround for now.
3189 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3190 to return the remote port by socket.
3192 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3195 SILC_SERVER_PENDING_EXEC and added an new macro
3196 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3197 data or when error occurs while processing the pending command.
3199 Added new argument `destructor' into silc_server_command_pending
3200 and to the SilcServerCommandPending object. This destructor is
3201 now called after calling the pending callback or if error occurs
3202 immediately. If error occurs the actual pending callback won't
3203 be called at all - only the destructor. The destructor may be
3204 NULL if destructor is not needed.
3206 All this applies for client library code as well. Similar
3207 changes were made there as well for the pending commands.
3209 In the client, the application must now allocate the
3210 SilcClientCommandContext with the silc_client_command_alloc
3213 * Added reference counter to the SilcServerCommandContext. Added
3214 function silc_server_command_alloc and silc_server_command_dup
3217 Same type of functions added to the client library for the same
3220 * Removed the cmd_ident from IDListData away since it is now
3221 global for all connections. It is the command identifier used
3222 in command sending and with pending commands. The affected file
3225 * Added reference counter to the SilcSocketConnection objecet to
3226 indicate the usage count of the object. The object won't be
3227 freed untill the reference counter hits zero. Currently only
3228 server uses this, and client ignores it. The client must be
3229 set to use this too later. The affected files are
3230 lib/silccore/silcsockconn.[ch]. Added also the function
3231 silc_socket_dup to increase the reference counter.
3233 This was mainly added because it is possible that the socket
3234 is removed underneath of pending command or other async
3235 operation. Now it won't be free'd and proper DISCONNECTING
3236 flags, etc. can be set to avoid sending data to connection that
3237 is not valid anymore.
3239 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3240 the connection. After that it sets SILC_SET_DISCONNECTED.
3241 It is, however, possible that the socket data is not still freed.
3242 The silc_server_packet_process now checks that data is not
3243 read or written to connection that is DISCONNECTED. The socket
3244 get's freed when the reference counter hits zero.
3246 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Changed the client operation API: channel_message operation's
3249 `sender' is now the client entry of the sender, not the nickname
3250 and the `channel' is the channel entry, not the channel name.
3252 In the private_message operation the `sender' is now also the
3253 client entry of the sender not the nickname.
3255 Affected file is lib/silcclient/ops.h and all applications
3256 using the client operations.
3258 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Moved the calling of ops->connect() from connect_to_server_final
3261 into receive_new_id functin since that is the point when the
3262 client is actually allowed to send traffic to network. The
3263 affected file is lib/silcclient/client.c.
3265 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3268 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3269 (if needs broadcasting) instead of broadcasting the packets one
3270 by one which would make a burst in the network traffic.
3272 * Added `broadcast' argument to the functions in silcd/server.[ch]
3273 silc_server_create_new_channel[_with_id] to indicate whether
3274 to send New Channel packet to primary router.
3276 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Added new function into the silcd/server.[ch] files:
3279 silc_server_create_new_channel_with_id to create new channel with
3280 already existing Channel ID.
3282 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3283 lib/silccore/silcpacket.h. This packet is used t send list of
3284 Set Mode payloads inside one packet. Server uses this to set
3285 the modes for the channels and clients on those channels, that it
3286 announced to the router when it connected to it. The protocol
3287 specification has been updated accordingly.
3289 * The silc_server_new_channel did not handle the packet coming
3290 from normal server as it normally does not send that. However,
3291 when it announces its channels it does send it. Implemented
3292 the support for that.
3294 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3295 into the file lib/silccore/id.h.
3297 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Fixed memory leaks in the functions silc_idlist_del_client,
3300 silc_idlist_del_channel and silc_idlist_del_server in the file
3301 silcd/idlist.c. All of those leaked like a sieve.
3303 * Fixed some small memory leaks in the client's function
3304 silc_client_notify_by_server.
3306 * Added functions into silcd/server.c: silc_server_announce_clients,
3307 silc_server_announce_channels and silc_server_announce_server.
3308 These functions are used by normal and router server to announce
3309 to its primary router about clients, channels and servers (when
3310 router) that we own. This is done after we've connected to the
3313 These functions effectively implements the following packet types:
3314 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3315 and SILC_PACKET_NEW_ID_LIST.
3317 * Added new functions into the silcd/packet_receive.[ch]:
3318 silc_server_new_id_list, silc_server_new_channel_list and
3319 silc_server_new_channel_user_list to handle the incoming
3320 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3322 * Added support of changing Channel ID in the function
3323 silc_server_replace_id. If the server that announces a channel
3324 to the router already exists in the router (with same name but
3325 with different Channel ID), router is responsible to send
3326 Replace ID packet to the server and force the server to change
3327 the Channel ID to the one router has.
3329 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3330 client that the Channel ID has been changed by the router. The
3331 normal server sends this to the client. Client must start using
3332 the new Channel ID as the channel's ID.
3334 Implemented handling of this new type into lib/silcclient/client.c
3335 into the function silc_client_notify_by_server.
3337 * Added new function silc_idlist_replace_channel_id into the files
3338 silcd/idlist.[ch] to replace the Channel ID.
3340 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Call silc_server_command_identify_check always when processing
3343 the IDENTIFY command in silcd/command.c
3345 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3348 send keepalive packets. The packet can be sent by clients,
3349 servers and routers.
3351 Added function silc_socket_set_heartbeat into the file
3352 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3353 If not set, the heartbeat is not performed. The actual
3354 heartbeat is implemented in the low level socket connection
3355 library. However, application is responsible of actually
3358 Added silc_server_send_heartbeat to send the actual heartbeat
3359 packet into silcd/packet_send.[ch]. Server now performs
3360 keepalive with all connections.
3362 * Added silc_task_get_first function into lib/silcutil/silctask.c
3363 to return the timeout task with shortest timeout. There was a bug
3364 in task unregistration that caused problems. TODO has been
3365 updated to include that task system must be rewritten.
3367 * The client library will now resolve the client information when
3368 receiving JOIN notify from server for client that we know but
3369 have incomplete information.
3371 * Rewrote parts of silc_server_remove_from_channels and
3372 silc_server_remove_from_one_channel as they did not remove the
3373 channel in some circumstances even though they should've.
3375 * Encryption problem encountered in server:
3377 The LEAVE command used to send the Channel Key packet to the
3378 router immediately after generating it. However, the code
3379 had earlier sent Remove Channel user packet but not immediately,
3380 ie. it was put to queue. The order of packets in the router
3381 was that Channel Key packet was first and Remove Channel User
3382 packet was second, even though they were encrypted in the
3383 reverse order. For this reason, MAC check failed. Now, this
3384 is fixed by not sending the Channel Key packet immediately but
3385 putting it to queue. However, this is more fundamental problem:
3386 packets that are in queue should actually not be encrypted
3387 because packets that are sent immediately gets encrypted
3388 actually with wrong IV (and thus MAC check fails). So, packets
3389 that are in queue should be encrypted when they are sent to
3390 the wire and not when they put to the queue.
3392 However, the problem is that the current system has not been
3393 designed to work that way. Instead, the packet is encrypted
3394 as soon as possible and left to the queue. The queue is then
3395 just purged into wire. There won't be any fixes for this
3396 any time soon. So, the current semantic for packet sending
3399 o If you send packet to remote host and do not force the send
3400 (the packet will be in queue) then all subsequent packets to the
3401 same remote host must also be put to the queue. Only after the
3402 queue has been purged is it safe again to force the packet
3405 o If you send all packets immediately then it safe to send
3406 any of subsequent packets through the queue, however, after
3407 the first packet is put to queue then any subsequent packets
3408 must also be put to the queue.
3410 Follow these rules and everything works fine.
3412 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Added new function silc_server_remove_clients_by_server to
3415 remove all client entries from ID list when the server connection
3416 is lost. In this case it is also important to invalidate all
3417 client entires as they hold the invalid server entry. This
3418 fixes fatal bug when server has lost connection and will reconnect
3421 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Made some sanity checks to silc_server_daemonise like to check
3424 whether the requested user and group actually exists.
3426 * Added sanity check to SKE's silc_ske_responder_finish to check
3427 that the public and private key actually is valid.
3429 * Invalidate the client's nickname when receiving Replace ID
3430 packet and the Client ID is being replaced. This means that the
3431 server will query the nickname if someone needs it (client)
3434 * Sort the ID Cache in client library when the ID Cache data
3435 has changed (needs sorting).
3437 * Do not allow for SILC client to create several connections to
3438 several servers. The client does not support windows right now
3439 and generating multiple connections causes weird behaviour.
3441 Irssi-silc client does support windows and can handle several
3442 connections without problems, see: www.irssi.org and SILC plugin.
3444 * Fixed some places where client was added to the IDList. The
3445 rule of thumb is following (in order to get everything right):
3446 If the client is directly connected local client then the
3447 `connection' argument must be set and `router' argument must be
3448 NULL to silc_idlist_add_client function. If the client is not
3449 directly connected client then the `router' argument must
3450 bet set and the `connection' argument must be NULL to the
3451 silc_idlist_add_client function.
3453 * The funtion silc_server_packet_send_local_channel actually did
3454 not check whether the client was locally connected or not. It
3455 does that now. Fixed a bug related to LEAVE command.
3457 * Fixed Remove Channel User payload parsing bug in server's
3458 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3460 * The server's silc_server_save_channel_key now checks also the
3461 global ID list for the channel as it might not be in the local
3462 list. Fixed a bug related to LEAVE command.
3464 * Is this the end of the [<unknown>] buglet that has been lurking
3465 around for a long time? A little for loop fix in server's
3466 silc_server_command_whois_parse that is used by both IDENTIFY
3467 and WHOIS command. At least, this was a clear bug and a cause
3468 of one type of [<unknown>] buglet.
3470 * WHOIS and IDENTIFY commands call the function
3471 silc_server_command_[whois/identify]_check function even if
3472 we are not router server.
3474 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Added --with-gmp configuration option. If set the GMP
3477 is always compiled in the SILC source tree. If not set then
3478 it is checked whether the system has the GMP3 installed. If
3479 it has then the GMP won't be compiled (the system's headers
3480 and library is used), if it doesn't have it then the GMP is
3481 compiled in the SILC source tree.
3483 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Changed RSA private exponent generation to what PKCS #1
3486 suggests. We try to find the smallest possible d by doing
3487 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3488 not security fix but optimization.
3490 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Added new config entry [Identity] to fork the server and run
3493 it as specific user and group. A patch from Bostik.
3495 * Imported Dotconf configuration library into lib/dotconf.
3496 This will be used to create the SILC configuration files later.
3497 It will appear in the distsribution after this commit.
3499 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * A big code auditing weekend happening. Auditing code for
3502 obvious mistakes, bugs and errors. Also, removing any code
3505 Removed files for being obsolete:
3507 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3508 inline in the file lib/silcutil/silcbuffer.h)
3510 o lib/silcutil/silcbufutil.c (the header has inline versions)
3512 Changed code to fix possible error conditions:
3514 o The buffer formatting routines now check that the destination
3515 buffer really has enough space to add the data. This applies for
3516 both buffer formatting and unformatting
3517 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3518 unformatting was changed to accomodate following rules:
3519 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3520 sent to the function while XXX_*STRING will not allocate or copy
3521 the data into the buffer. Instead it sets the pointer from the
3522 buffer into the pointer sent as argument (XXX_*STRING used to
3523 require that the pointer must be allocated already). This change
3524 makes this whole thing a bit more consistent and more optimized
3525 (note that the data returned in the unformatting with XXX_*STRING
3526 must not be freed now). The routines return now -1 on error.
3528 o Tried to find all code that use buffer_format and buffer_unformat
3529 and added return value checking to prevent formatting and
3530 especially unformatting errors and possible subsequent fatal
3533 o Changed ske->x and ske->KEY to mallocated pointers in
3534 lib/silcske/silcske.h. Fixed possible data and memory leak.
3536 o Added return value checking to all *_parse* functions. Fixed
3537 many memory leaks as well.
3539 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3540 so that buffer overflows would not happen. All code now also
3541 checks the return value as it can fail.
3543 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Added reconnection support to server if the normal server looses
3546 its connection to the router (for example if router is rebooted).
3547 The server performs normal reconnection strategy implemented
3548 to the server. Affected file silcd/server.c.
3550 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Added new packet type SILC_PACKET_SET_MODE that is used to
3553 distribute the information about changed modes (for clients,
3554 channels and clients channel modes) to all routers in the
3555 network. Updated the protocol specification accordingly.
3557 Added functions into silcd/packet_send.c and
3558 silcd/packet_receive.c: silc_server_send_set_mode,
3559 silc_server_set_mode.
3561 Added new files silcmode.[ch] into lib/silccore that implements
3562 the encoding and decoding of Set Mode Payload. Added new type
3563 SilcSetModePayload. Moved the definitions of different modes
3564 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3566 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Oops, a little mistake in server's connection authentication
3569 protocol. The protocol is not ended with FAILURE but with
3570 SUCCESS if the authentication is Ok. :) Affected file is
3573 * Implemented NICK_CHANGE notify handling in server in the file
3574 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3575 the local clients on the channel. After the changing nickname
3576 in router environment snhould work and the [<unknown>] nickname
3577 should appear no more.
3579 The silc_server_replace_id function that receives the Replace ID
3580 payload now sends the NICK_CHANGE notify type also in the file
3581 silcd/packet_receive.c
3583 * Changed WHOIS and IDENTIFY command to support the maximum amount
3584 of arguments defined in protocol specs (3328 arguments). This
3585 fixed a bug that caused problems when there were more than three
3588 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Added extra parameter, command identifier, to the
3591 silc_client_send_command so that explicit command identifier
3594 Changed that ID list routines uses specific command identifier
3595 when sending WHOIS/IDENTIFY requests to the server so that they
3596 can be identified when the reply comes back.
3598 Affected files lib/silcclient/command.[ch],
3599 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3601 * Added `sender' argument to silc_server_packet_send_to_channel
3602 to indicaet the sender who originally sent the packet to us
3603 that we are now re-sending. Ignored if NULL. Affected file
3604 silcd/packet_send.[ch].
3606 * Added some server statistics support in silcd/server_internal.h
3607 SilcServerStatistics structure and around the server code. Also
3608 send some nice statistics information when client is connecting
3611 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Fixed channel ID decoding in server's JOIN command reply in
3614 silcd/command_reply.c
3616 * Fixed braodcasting of replace ID payload to not to send it if
3617 we are standalone server in silcd/packet_receive.c.
3619 * Fixed all channel message sending routines to not to send
3620 packets to clients that has router set, since they are routed
3621 separately in the same function earlier. Affects file
3622 silcd/packet_send.c and all channel packet sending functions.
3624 * In USERS reply, res_argv[i] are not allocated, the table
3625 is allocated. Thus changed that free the table, not its
3628 * In server's whois_check and identify_check if the client is
3629 locally connected do not send any WHOIS commands - they are not
3632 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Fixed some minor bugs in client when sending WHOIS command. The
3635 arguments was in wrong order.
3637 * Removed statis function add_to_channel from server in
3638 silcd/command.c that was previously used with the joining but
3641 * Tested USERS command in router environment successfully with two
3642 routers, two servers and two clients.
3644 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Reorganized the USERS command and command reply in client library
3647 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3648 When the command is given by user we register a pending command
3649 callback that will reprocess the command after the reply has been
3650 received from the server. When reprocessing the packet we then
3651 display the information. Thus, the USERS information is displayed
3652 now in the command callback instead of in the command reply
3653 callback. The processing of the command is same as previously
3654 when server has sent the command reply in the JOINing process.
3656 * Added to USERS command in silcd/command_reply.c to join the client,
3657 we didn't use to know about, to the channel after we've created
3658 a client entry for it. Also, for clienet we did know already still
3659 check whether it is on the channel or not and add it if not.
3661 * Removed silc_server_command_join_notify as the function and its
3664 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Changed the client's pending command handling to the same as the
3667 server's pending command handling. It is also now possible to
3668 execute command reply functions from other command reply
3669 function as the function callbacks for commands and command
3670 replies are one and same. The pending commands are not static
3671 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3672 in client connection context. Thus, pending commands are server
3673 connection specific as it is convenient.
3675 Changed the function silc_client_command_pending and
3676 silc_client_command_pending_del and added new function
3677 silc_client_command_pending_check. Removed the
3678 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3681 * Added cmd_ident, current command identifier, to the client
3682 connection context in lib/silcclient/client.h to keep track on
3683 command identifiers used in command sending. Client's command reply
3684 function handling now supports the mandatory command identifiers.
3686 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3687 funtions in client to fully support pending command callbacks.
3689 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3690 as one of the arguments to the application in the command reply
3693 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3694 before first releasing SILC but came back. Now it is removed again
3695 and should come back nomore. The FORWARDED flag was used only
3696 by the JOINing procedure by forwarding the command packet to router.
3697 Now, the JOINing procedure has been changed to more generic (due
3698 to various router environment issues) and FORWARDED is not needed
3699 anymore for anything. The protocol specification is yet to be
3702 Now, removed silc_server_packet_forward from server and the flag
3703 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3705 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Renamed NAMES command to USERS command. The NAMES was named that
3708 due to historical reasons. Now it is renamed. Also, rewrote
3709 parts of the USERS command. The nickname list is not sent anymore
3710 by the server. Only Client ID and mode lists are sent in the USERS
3711 command. Changed this also to the protocol specification.
3713 The client now resolves the names and stuff after it receives
3714 the USERS list from the server when joining to the channel.
3716 * WHOIS and IDENTIFY commands has been changed to support multiple
3717 Client ID's per command. One can now search for multiple users
3718 in the network by sending only one WHOIS or IDENTIFY command.
3719 Changed the code and the protocol specifications.
3721 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3722 uses silc_server_command_whois_parse to parse the request. */
3724 * If normal server, do not parse the WHOIS and IDENTIFY requests
3725 before sending it to the router. Saves some time.
3727 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Fixed JOIN command on client library. Wrong number of arguments
3730 used to crash the client.
3732 * Added silc_server_channel_has_global function to check whether
3733 channel has global users or not.
3735 * Added silc_server_channel_has_local function to check whether channel
3736 has locally connected clients on the channel.
3738 * The silc_server_remove_from_one_channel now checks whether the
3739 channel has global users or not after given client was removed from
3740 the channel. It also checks whether the channel has local clients
3741 on the channel anymore. If it does not have then the channel entry
3742 is removed as it is not needed anymore.
3744 * The silc_server_notify now checks on JOIN notify whether the joining
3745 client is one of locally connected or global. If it is global then
3746 the channel has now global users on the channel and that is marked
3747 to the channel entry. Also, it now saves the global client to
3748 global list who is joining and JOINs it to the channel. This is
3749 for normal server, that is.
3751 Changed silc_server_send_notify_on_channel,
3752 silc_server_packet_relay_to_channel and
3753 silc_server_packet_send_to_channel check if we are normal server
3754 and client has router set (ie. global client) do not send the
3755 message to that client, as it is already routed to our router.
3757 * Implemented LEAVE notify type handling in silc_server_notify
3760 * Tested LEAVE command in router environment successfully. Tested
3761 with two routers, two servers and two clients.
3765 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3767 * Implemented SIGNOFF notify type handling in silc_server_notify
3770 * silc_server_remove_id now removes the client entry from all channels
3771 it has joined and thusly sends SIGNOFF notify type.
3773 * Rewrote the NAMES list generation in server by removing two excess
3774 loops. The lists are created now inside one loop.
3776 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * silc_server_remove_channel_user checks now also global list
3779 for channel and client.
3781 * silc_server_new_channel_user checks now both local and global
3782 list for channel and client. Fixed a bug in client id decoding.
3783 Used to decode wrong buffer.
3785 * silc_server_channel_message checks now both local and global
3786 list for channel entry.
3788 * Tested channel joining (hence JOIN) in router environment
3789 successfully. Tested with two routers, two servers and two
3792 * Tested channel message sending in router environment successfully.
3794 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Added silc_server_save_channel_key into server.[ch] to save the
3797 received channel key in Channel Key payload processing. It is
3798 also used in JOIN command reply handling.
3800 Equivalent function silc_client_save_channel_key added into
3801 client.[ch] into client library.
3803 * Changed JOIN command reply to send information whether the channel
3804 was created or not (is existing already) and the channel key
3805 payload. Changed protocol specs accordingly.
3807 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3808 the request was sent by ID and not by nickname. Crashed on
3811 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3814 now correctly save the received data.
3816 * silc_server_free_sock_user_data now notifies routers in the
3817 network about entities leaving the network.
3819 At the same time implemented functions silc_server_remove_id
3820 and silc_server_send_remove_id to receive and send REMOVE_ID
3821 packets. The packet is used to notify routers in the network
3822 about leaving entities. The ID removed will become invalid in
3825 * Added function silc_idlist_del_server into server. Removes and
3826 free's server entry from ID list.
3828 * silc_server_private_message function now checks, if we are router,
3829 that the destination ID really is valid ID, naturally.
3831 * In router when NEW_ID packet is received (for new client) the
3832 hash of the Client ID is saved in the ID Cache but the
3833 client->nickname is set to NULL, instead of putting the hash
3836 IDENTIFY command now also checks that client->nickname must be
3837 valid. If it is not if will request the data from the server who
3838 owns the client. Added new function
3839 silc_server_command_identify_check.
3841 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3842 to set the command to already allocated Command Payload.
3844 * Tested private message sending in router environment with two
3845 routers, two servers and two clients. Fixed minor bugs and now
3848 * Fixed segfault from client's NAMES command. Used to crash if
3851 * Forwarded packets must not be routed even if it is not destined
3852 to the receiver. Changed server code comply with this.
3854 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Added `require_reverse_mapping' boolean value to ServerParams
3857 structure. If TRUE (not default) the server will require that
3858 the connecting host has fully qualified domain name.
3860 If the reverse mapping is not required and hostname could not be
3861 found the IP address is used as hostname.
3863 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Implemented version string checking to both client and server.
3866 The check is incomplete currently due to the abnormal version
3867 strings used in development version of SILC.
3869 * Changed all command functions in server to use the new
3872 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Changed char *data to unsigned char *data in ID Cache system to
3875 support binary data as ID Cache data. Changed code to support
3876 binary data in lib/silccore/idcache.c.
3878 * Renamed silc_server_packet_relay_command_reply to
3879 silc_server_command_reply as it is normal packet receiving
3880 function. Rewrote the function to accept command replys for
3881 servers and not only for clients.
3883 * Mark remote router always as registered server if we are connecting
3884 to it. Otherwise, commands sent by the router to us are ignored.
3886 * All ID List find routines now returns the ID Cache Entry pointer
3887 as well if requested.
3889 * WHOIS command works now in router environment, tested with two
3890 routers, two servers and two clients.
3892 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3893 in router environment (as it is almost equivalent to WHOIS) but
3894 hasn't been tested thoroughly. Added new functions:
3896 silc_server_command_identify_parse
3897 silc_server_command_identify_send_reply
3898 silc_server_command_identify_from_client
3899 silc_server_command_identify_from_server
3901 * Disabled route cache adding because adding two different ID's with
3902 same IP replaces the old cache entry thus giving wrong route.
3903 The entry->router->connection is always the fastest route anyway
3904 so route cache may not be needed. Of course, new routes maybe
3905 established after receiving the ID when the entry->router->connection
3906 might not be anymore the most optimal.
3908 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Add route cache for received ID for fast routing.
3912 * Added silc_server_packet_route to route received packet on router
3913 that is not destined to us.
3915 * Renamed silc_server_get_route to silc_server_route_get.
3917 * Added id_string and id_string_len fields into SilcServer to
3918 include encoded ServerID for fast comparing without excess
3919 encoding of the ID's.
3921 * Cleaned up WHOIS command on server side. Added following static
3924 silc_server_command_whois_parse
3925 silc_server_command_whois_check
3926 silc_server_command_whois_send_reply
3927 silc_server_command_whois_from_client
3928 silc_server_command_whois_from_server
3930 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3931 arguments in command replies. All command functions should be
3932 updated to use this macro.
3934 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Minor typo fixes on command reply handling on server.
3938 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added silc_server_command_add_to_channel internal routine to add
3941 the client to the channel after router has created the channel and
3942 sent command reply to the server.
3944 * Added generic silc_server_send_command to send any command from
3947 * Use static buffer with ID rendering instead of duplicating data.
3949 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Fixed a channel user mode bug when joining to a channel server gave
3952 everybody channel founder rights, oops.
3954 * We mark ourselves as the router of the incoming server connection
3955 if we are router ourselves. This way we can check in some packet
3956 sending functions whether it is locally connected server. For
3957 incoming router connections we put NULL.
3959 * For router sending packets locally means now always sending the
3960 packet cell wide; to local clients and local servers. For normal
3961 server sending packet locally means sending it to only local
3964 * Fixed the JOIN command to really work in router environment. If the
3965 channel is created it is always created by the router. Router is
3966 also responsible of making the initial joining to the channel,
3967 sending JOIN notify to the sending server and distributing
3968 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3969 does not exist server doesn't do anything else but forward the
3970 command to the router which performs everything.
3972 * Added silc_server_send_channel_key function to send the Channel Key
3975 * Added silc_server_create_channel_key to create new channel key. The
3976 channel key is now re-generated everytime someone joins or leaves
3977 a channel, as protocol dictates. Note: channel->key_len is the
3980 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3983 packet_receive.[ch] to separate packet sending and receiving
3984 routines. The server.[ch] now includes everything else including
3985 actual packet processing (writing and reading data) and other
3988 Renamed silc_server_private_message_send_internal to
3989 silc_server_send_private_message. The routine is still though
3990 used only to relay private messages as server does not send
3991 private messages itself.
3993 Renamed silc_server_new_channel to silc_server_create_new_channel
3994 and added new function sicl_server_new_channel that handles the
3995 incoming New Channel packet. Added also new sending function
3996 silc_server_send_new_channel to send New Channel Payload.
3998 * Added new function silc_server_notify to process incoming notify
3999 packet to the server/router. Server may then relay the notify
4000 to clients if needed.
4002 * Added new function silc_server_new_channel_user to process incoming
4003 New Channel User packet. Router will redistribute the packet and
4004 send JOIN notify to its local clients and locally connected servers
4005 if needed. Normal server will send JOIN notify to its local client
4006 on same channel when received this packet. Added also corresponding
4007 sending function silc_server_send_new_channel_user to sent the
4010 * Added boolean route argument to send_notif_to_channel and
4011 packet_send_to_channel functions to attempt to route the packet
4012 if it is TRUE and send only locally if it is FALSE.
4014 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * silc_server_replace_id now broadcasts the received replace ID
4017 packet if it is not broadcast packet already. The router must
4018 broadcast to inform other routers about changed ID.
4020 * Added backpointer to server's router into SilcServer context in
4021 silcd/server_internal.h.
4023 * Fixed silc_server_packet_broadcast to send correct broadcast
4026 * The channel key is now distributed to the local client as soon
4027 as it is received from the router (in router environment) so that
4028 no other packet may be sent for the channel until client has
4031 * silc_server_remove_channel_user now broadcasts the received
4032 Remove Channel User packet if it is not broadcast packet already.
4033 The router must broadcast to inform other routers about removed
4036 * Added users field into SilcPacketContext that is a reference count
4037 of the context. One can increase the reference count by calling
4038 silc_packet_context_dup which is now changed to just increase the
4039 reference count instead of duplicating the data. The reference
4040 count is decresed by calling silc_packet_context_free that will
4041 free the data after the reference count hits zero.
4043 For now on the packet context and everything allocated into it
4044 (including the raw packet from network) must be freed by calling
4045 the new silc_packet_context_free function. Added also new function
4046 silc_packet_context_alloc that must be used now to allocate the
4047 context. This also means that if a routine is asynchronous from
4048 silc_[client/server]_packet_parse_type the packet context must
4049 be duplicated by calling silc_packet_context_dup. Otherwise it
4050 gets free'd after silc_[client/server]_packet_parse_type returns.
4051 Also, one must remember that if packet is duplicated then its
4052 reference count must be decresed by calling the free function as
4053 many times as it was duplicated.
4055 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4056 from both client and server.
4058 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Made joining to a channel working in router environment.
4062 * Cleaned up JOIN command on server side and create function
4063 silc_server_command_join_channel internal routine to make the
4066 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Changed silc_command_pending list to SilcDList. Also, added
4069 `ident' field to SilcServerCommandPending structure to identify
4070 the reply and to call correct callback.
4072 Added silc_server_command_pending_check function to replace the
4073 corresnponding macro. The silc_command_pending list is not
4076 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4077 to set identifier to previously allocated Command Payload. It
4078 is used to set identifier for command when resending Command
4081 * Added silc_command_payload_encode_payload to encode Command
4082 Payload buffer from SilcCommandPayload structure.
4084 * Added silc_argument_payload_encode_payload to encode Argument
4085 payload buffer from SilcArgumentPayload structure.
4087 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Changed WHOIS command to support router connection on server side.
4090 The whois request is always sent to router unless the server is
4091 standalone server. After server has received the reply from the
4092 router will it send the reply to the client.
4094 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4095 broadcast received broadcast packet. The function is used only
4096 by router. The broadcast packet is always sent to the router's
4099 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4100 render given ID to printable string, for log files for example.
4102 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Made basic router to router connections working. At least they
4105 can now connect to each other but nothing really works the way
4106 they are supposed - yet.
4108 * Added new initiator token to RouterConnection configuration
4109 file in silcd/serverconfig.[ch]. It is used to tell whether we
4110 are the initiator to the remote router or whether we'll expect
4111 the other end to connect.
4113 * Moved registering of listener task to silc_server_init, hence
4114 the server starts listenning as soon as it is run, even if it
4115 does not have connections to other routers. Let's see how well
4118 * Changed default connection retry timeouts for more suitable in
4121 * Removed cipher and such arguments from silc_idlist_add_client
4122 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4123 Added new function silc_idlist_add_data to add the keys and stuff
4126 * Added SilcIDListData structure and added it to SilcClientEntry
4127 and SilcServerEntry as their first field in the structure. This
4128 way we can explicitly cast the ID entries to the SilcIDListData
4129 structure and get common data for the entries. In past, we had
4130 to first check what type of connection it is and then cast it to
4131 correct ID entry type. Now, we can directly cast the opaque
4132 pointer to the SilcIDListData (no matter what ID entry it actually
4133 is) and get the data needed.
4135 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4138 in some circumstances even if threre were timeout tasks, though not
4139 IO tasks, but tasks anyway. Now fixed.
4141 * Defined SilcServerConnection structure to hold connection specific
4142 stuff about directly connected servers and routers. The definition
4143 is currently in silcd/server_internal.h. I thought about having
4144 a bit more important role fro this struct but for now it is used
4145 only when connecting to other server (or router actually).
4147 * Added connecting retry support in server when connecting to
4148 router(s). The retry feature implement exponential backoff
4149 algorithm. Also, added SilcServerParams structure to hold default
4150 parameters for server. For now, it include these retry settings
4151 and are hard coded. After server is moded to be as Silc Server
4152 Library this structure will be more important.
4154 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Changed client librarys channel->clients table to SilcList and
4157 changed code accordingly.
4159 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Changed client's channel table to SilcList and changed code
4162 accordingly. Also changed SilcChannelClientEntry to include back-
4163 pointer to the channel so that client entry can use that structure
4164 as list as well and we have fast cross-reference to the channel.
4165 This change dramatically decreased the complexity of channel
4166 handling with client entry and vice versa (removed one extra
4167 loop when searching for channel entry from many functions).
4169 * Changed server->sim from table to SilcDList and changed code
4172 * NAMES command can now be used from user interface. It will show
4173 the user list on the channel, neatly.
4175 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4176 Code now saves realname of the user if it becomes available.
4178 * Renamed configure.in to configure.in.pre and made ./prepare
4179 script to automatically add correct version string to
4180 configure.in which it creates from configure.in.pre.
4182 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * NAMES command reply now shows users mode with the nickname when
4187 * Moved silc_client_ch[u]mode[_char] functions from
4188 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4189 place sucks, they are utility functions and should be in some
4192 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4194 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4197 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Added TRQ (efficient deque and list library) into lib/trq. This is
4202 a very good list library that is currently used in the SILC. Defined
4203 SilcList API over the library because I didn't like the API very
4204 much. See lib/trq/silclist.h for the API and examples of how to
4205 use the API. Fixed various places in the code to use the new
4206 SilcList API. The SilcList is meant for lists that has a structure
4207 already defined as a list. It is not suitable to add just some
4208 context to the list (in TRQ, the context is the list actually).
4210 So, I defined SilcDList that can be used for the purpose where
4211 predefined list structure does not exit. This can be used as
4212 such list. Now some context just can be added to the SilcDList.
4213 Currently this list is not used in the SILC just yet, though there
4214 are a lot places where this can replace dynamically allocated
4215 tables and I will fix these places, later, to use SilcDList.
4216 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4217 and use TRQ internally).
4219 Also fixed some annoying warning messages that the original TRQ
4220 code generated. Also minor changes to TRQ's Makefile.in.
4222 * Added support for querying by Client ID to both WHOIS and
4223 IDENTIFY commands into server, as required by the protocol.
4225 * Removed method function pointers from SilcBuffer structure. They
4226 weren't used to anything and just increased the context size for
4227 no good reason. This change also made silc_buffer_alloc and
4228 silc_buffer_free functions inline functions.
4230 * Disabled command flooding detection support until it's fixed so
4231 that it accepts commands in but does not execute them more than once
4234 * Added silc_net_localhost(), to return local hostname, into
4235 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4236 that must be initialized before calling silc_client_init.
4238 * Added new function: silc_server_send_notify_on_channels to send
4239 notify messages to all channels client has joined. It is assured
4240 that the message is sent only once per client.
4242 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4243 lib/silcutil/silcutil.[ch] as silc_format function. The new
4244 function is generic and is used by server as well, not only by
4245 the logging routines.
4247 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4248 the provided version string was not acceptable. Added new function:
4249 silc_ske_check_version into lib/silcske/silcske.h. The function
4250 must be implemented by the application (client or server) and it
4251 does not reside in the SKE library. The function checks the version
4252 string remote end sent.
4254 * Added back pointers (to opaque context and to SilcSocketConnection)
4255 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4257 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4258 duplicate packet context structure.
4260 * Changed `notify' client operation to send same arguments as client
4261 receives from server except for ID's. ID's are mapped to correct
4262 ID entry and that is returned. Also, if channel entry is not sent
4263 by server but the notify is for channel the channel entry is sent
4264 to application (otherwise application doesn't know that it is for
4265 channel (library gets it from packet's Destination ID)).
4267 * Added silc_client_remove_from_channels into client library to
4268 remove a client from all channels it has joined to. Used when
4269 received SIGNOFF notify from server. Added also new function
4270 silc_client_replace_from_channels to replace old ID entry with
4271 new ID entry on all channels. Used when received NICK_CHANGE
4274 * Fixed ID Cache list handling in silc_idlist_get_client in
4275 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4276 to get (or query) client by ID.
4278 * Updated TODO list.
4280 * Added connection authentication status message defined by the
4281 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4282 support for these into the code in client and server side.
4284 * Added generic function silc_client_send_command to send any command
4285 with variable argument list. Application should use this function
4286 to send commands if the command functions provided by the library
4287 does not suite for the application's user interface needs.
4289 * Added new `failure' client operation. Application is notified about
4290 received failure packet if client is executing a protocol. In this
4291 case the protocol's execution has failed.
4293 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4294 is required by the protocol.
4296 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4297 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4300 * Added status flag to SilcSKE object to indicate realtime status
4301 of the SKE protocol.
4303 * Application receives now exactly same command reply arguments as
4304 the library receives from server. However, if ID is received the
4305 corresponding ID entry is returned to the application (eg. Client
4306 ID is mapped to correct SilcClientEntry entry and that is returned).
4307 Changed command_reply client operation due to this change.
4309 * Changed all ID's in commands and in command replys as ID Payloads.
4310 Change affected both client and server side codes.
4312 All ID's sent in SILC network (with execption of ID's in SILC
4313 Packet header) are sent in ID Payload to support variable length
4316 * Server now notifies nick changes and notifies all clients on
4317 the channels about the new nickname (about the new Client ID,
4320 * Implemented CMODE command to change channel modes. Supports all
4321 channel modes defined by the protocol specs except ban and invite
4322 lists. (Also, private channel key mode is supported but support for
4323 setting private channel key in client is missing, thus, this mode
4324 has no effect on client side (except that server requires that the
4325 client uses private channel key and normal channel traffic does not
4328 Also, invite mode works per se, but INVITE command does not work
4329 yet correctly, so you can set channel as invite only channel but
4330 inviting clients to the channel does not work (it is yet to be
4331 thought what's the best way to do it).
4333 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4334 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4335 Implemented CUMODE command to change user's mode on the channel.
4336 Supports all modes defined by the protocol specs.
4338 * Added NAMES command reply to return users modes on the channel.
4340 * Removed unnecessary and slow ciphers from lib/silccrypt.
4342 * Set SO_KEEPALIVE option to connection sockets by default.
4344 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4346 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4347 redefined the Notify Payload into protocol specs.
4349 * Added silc_id_payload_parse_id to get ID directly from raw
4352 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4355 accept searching by Client ID as well.
4357 * Added support for LEAVE and SIGNOFF notify types in client library.
4359 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4360 to parse ID Payload from raw data.
4362 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Added flags parameter into silc_ske_assemble_security_properties
4365 function in lib/silcske/silcske.[ch].
4367 * Changed notify client operation to fit better for notify messages
4368 sent by server. The notify payload received from server is now
4369 passed to the application (after parsing it to SilcNotifyPayload).
4370 It is application's responsibility to retrieve the arguments
4371 from the payload and show the message the way it wants. The message
4372 sent by server is implementation specific.
4374 * Changed public keys to comply with the protocol specification.
4375 Old public keys are not supported anymore and are not compatible.
4377 * Removed nickname from Channel Payload as the latest draft removed
4378 it. The client must resolve the nickname from the NAMES command
4379 reply received when it joined the channel.
4381 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4383 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Fixed some errors in protocol specification drafts.
4387 * Created lib/silccore/silcnotify.c to implement Notify Payload
4388 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4389 generic payloads described by protocol specifications. The file
4390 includes implementations for ID Payload and Argument Payload.
4392 * Changed Command Payload implementation to use the new Argument
4393 Payload. Changed command_xxxx_payload to command_payload_xxxx
4394 to comply with SILC coding conventions.
4396 * Added suppport for Argument Payload handling in Notify Payload
4397 implementation as protocol requires it. Added the new support
4398 into server and client lib as well.
4400 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added support for multiple nicknames on same channel. [n] is
4403 added locally to the nickname if there are more than one same
4404 nicknames on the channel.
4406 * Server now sends all nicknames that matched WHOIS request.
4407 Client also shows the list received from server.
4409 * Added TOPIC command to client side. User can now set and show
4410 current topic on channel.
4412 * Added MOTD command to client and server. Also, server sends the
4413 motd when client connects to the server.
4415 * Changed version strings to comply ISO 8601.
4417 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Fixed protocol error handling in client library. It should now
4420 cope even if the SKE fails for some reason.
4422 * Made new protocol specification drafts for submitting to IETF.
4424 * Implemented TOPIC command to server in silcd/command.c.
4426 * Added two new notify types into lib/silccore/silcnotify.h:
4427 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4428 notify nickname change and topic setting/change on a channel.
4430 * API change of command_reply operation in client library. The
4431 application gets now the status type received from server as well.
4433 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4437 * Cras fixed and optimized the packet handling even further and
4438 it should work now. Minor change to the prototype of function
4439 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4441 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Added new function into lib/silcutil/silcschedule.[ch]:
4444 silc_schedule_with_fd to select() a specified fd. The function
4445 returns after timeout expires or data arrives or goes. The
4446 function is used by packet routines to wait that all data is
4447 received from network.
4449 * Fixed data reading from network in lib/silccore/silcpacket.c.
4450 The code now assures that all data is read from the fd and then
4451 continues packet processing. This was a bug fix since the code
4452 used to drop some data in some circumstances.
4454 * Added new function into lib/silcclient/client.[ch]:
4455 silc_client_start_key_exchange to start key exchange after
4456 connection has been established to server. The code internally
4457 now uses this funtion but its main purpose was to provide it
4458 for applications that perform their own connecting. After
4459 application has created a connection it merely calls this
4460 function to start the key exchange between client and server.
4461 The library takes care of everything else after that.
4463 Updated also lib/silcclient/README to explain the usage of
4466 * Do not send to application information that connection has
4467 been established. Application gets notified it by connect
4470 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Applied cras's patch to add silc_schedule_one function. The
4473 function runs scheduler once and returns.
4475 * Fixed the scheduler after cras messed it up. The timeout
4476 handling works now as it's supposed to work.
4478 * Added into lib/silccore/ silcnotify.h to include notify
4479 message types support. Changed silc_server_send_notify*
4480 functions, in server.[ch], to support those new notify types.
4481 Added the support for the notify types into client library,
4482 as well. Added new notify client operation into ops.h in
4485 * Changed silc_server_packet_send_to_channel to send normal
4486 packets instead of just channel message packets. The function
4487 is now used to send the notify packets to channels. It is not
4488 used to send channel message packets anymore, as server never
4491 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4492 va_arg()s as it seems to require it nowadays. I guess, if SILC
4493 is compiled with older va_arg() the new code should work anyway.
4495 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Splitted core library. Core library (lib/silccore) includes
4498 now only SILC protocol specific core (and common) components.
4499 Created new utility library (lib/silcutil) that includes more
4500 generic purpose stuff. The stuff for util library was taken
4501 from the old core library. This was minor and easy split.
4503 * Created SILC Client Library (lib/silcclient) that includes
4504 implementation of the SILC client without user interface. This
4505 was major move from silc/ directory. The code has been changed
4506 so that it is transparent towards the user interface. The
4507 silc/ directory includes now the same user interface as before
4508 and it uses the new client library. Read lib/silcclient/README.
4509 Basicly, the client library performs everything else related
4510 to SILC except user interface handling. Also, configuration
4511 files are considered to be part of user interface and library
4512 does not handle them.
4514 This change also changed a lot of structures, function naming etc.
4515 Most important change was that SilcClientWindow object was
4516 renamed to SilcClientConnection in the client library. Created
4517 also new file lib/silcclient/ops.h. Also added new files
4518 silc/local_command.[ch] and silc/client_ops.[ch].
4520 All these changes were made to make it easier for user interface
4521 designers to create what ever user interface for the SILC client
4524 It is also expected that the server will be moved to lib
4525 directory as well and SILC Server Library will be created;
4526 sometimes in the future.
4528 * Removed Local commands from lib/silccore/silccommand.h as
4529 they are application specific and new client library does not
4530 handle any of those anymore.
4532 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4533 old client implementation in silc/.
4535 * Added support for callback functions in SILC_LOG_* macros.
4536 Application can now set its own callbacks that will be called
4537 instead of using the default functions that will always print
4538 the debug messages to stderr (or stdout). Also, debugging can
4539 now be disabled by setting silc_debug to FALSE and re-enabled by
4540 setting it to TRUE. Note, that logging will still work even
4541 if debugging is disabled.
4543 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4544 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4545 silc_log_reset_debug_callbacks.
4547 * To enable debugging in silc client one must give now -d
4548 option on command line.
4550 * Changed silc_schedule_init to automatically allocate task queues
4551 if they are not allocated before calling it.
4553 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added GMP 3.1 into math library.
4557 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4560 a channel in SILC network. The packet is used by servers and
4561 routers to notify other routers that user has left a channel.
4562 This little feature was missing until now. Added the feature
4563 to protocol specification as well.
4565 Added functions: silc_server_send_remove_channel_user and
4566 silc_server_remove_channel_user into server.[ch].
4568 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4569 lib/silccore/silcpacket.h. However, they are not implemented
4572 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Fixed joining to a channel and sending channel messages
4575 between server and router. The channel message sending should
4576 now work inside a cell.
4578 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Fixed the private message sending between server and router.
4581 The private message sending should now work inside a cell.
4583 * Added silc_server_replace_id into server.[ch] to replace
4584 existing ID in the SILC network.
4586 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4587 and silc_idlist_replace_server_id into idlist.[ch] in server.
4589 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Fixed the server to server connections. Server can again now
4592 connect to router. Router to router connections probably does
4595 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added dynamic protocol registering support. Now protocols can
4598 registered and unregistered on the fly. Patch by cras.
4600 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added lib/contrib directory to hold routines that some platforms
4603 don't have but are needed by SILC.
4605 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4606 into lin/contrib to provide getopt() and getopt_long() for
4607 those who don't have it.
4609 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Added AWAY command to client. When away message is set and
4612 client receives a private message packet the client automatically
4613 replies to the sender with the away message.
4615 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4616 bug seemed to be the cause of recent problems when compiling
4619 * Added version detection support to SKE protocol specification
4620 and added the new changes to the SKE implementation as well.
4621 There were other minor changes in the SKE protocol as well.
4623 Many changes in lib/silcske/silcske.[ch] and in
4624 lib/silcske/payload.[ch].
4626 * Added ^U functionality, clear input line. Patch from cras.
4628 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Mainly small bugfixes on core library. Fixed some debugging
4631 logging and buffer overflow in silclog.c.
4633 * Updated config.sub and config.guess on the distribution tree.
4635 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Added command lagging support in server. Client may execute
4638 commands now only once in two seconds.
4640 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Optimized packet reception. MAC computation and checking is now
4643 also more optimized. A lot previously duplicated code is now
4644 used as generic by both client and server.
4646 * Fixed key pair generation in clientutil.c
4648 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Added into lib/silccore/silcbufutil.[ch] new function;
4651 silc_buffer_realloc.
4653 * Moved generic packet sending/encryption functions to
4654 lib/silccore/silcpacket.[ch] from client and server. Some
4655 rewriting of the functions.
4657 * Moved all generic packet reception/decryption functions to
4658 lib/silccore/silcpacket.[ch] from client and server. The
4659 packet processing is now much cleaner in both client and server.
4660 These were major changes in both client and server.
4662 * Created many common functions in server to do packet sending.
4663 Previously code were duplicated a lot, this has been removed
4666 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Rewrote major parts of the ID cache system. Don't know
4669 whether it is better now or not but at least the API is more
4672 * Major rewrite on ID cache stuff on client because of the ID
4673 cache API changes. Added idlist.c to client.
4675 * Also major rewrite on ID cache stuff on server as well.
4676 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4677 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4678 in hand, instead they are all put into the ID cache system now.
4679 All server_idlist_* routines uses ID cache now instead of
4680 traversing its own lists (those lists does not exist anymore).
4681 SilcIDList though still exists. Also, SilcXXXEntry's are
4684 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Finally made the SKE implementation compliant to the protocol
4687 specification. All mp integers are now binary encoded as
4688 opposed being HEX encoded.
4690 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4693 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4694 functions: silc_[encode/decode]_pem. Also added function
4695 silc_encode_pem_file to PEM encode with newlines ('\n') for
4698 * SILC public keys are now encoded either PEM or binary. Same
4699 option is for private keys as well. By default private keys
4700 are binary encoded and public keys PEM encoded. Silly HEX
4701 encoding were removed.
4703 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4704 function to create fingerprints.
4706 * Fixed a bug in SHA1; does not change the original data anymore.
4708 * Partly implemented INFO command on client and server side.
4709 Fixed CLEAR command. Changes to SERVER command; show current
4710 server(s) when giving command without arguments. Added
4711 VERSION command to client.
4713 * Added check to server that unregistered connections cannot
4714 execute commands (unless it is specificly allowed).
4716 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Fixed screen refresh.
4720 * Fixed channel joining bug from client. On some circumstances
4721 client tried to join to a channel it had already joined.
4723 * Added public key verification process into client's protocol.c.
4724 The client now verifies the public key from user and saves
4725 it into ~./silc/serverkeys/ directory.
4727 Added into: clientutil.[ch]: silc_client_verify_server_key.
4729 * Changed SKE protocol's silc_ske_initiator_finish function
4730 to accept callback function that verifies the received public
4731 key. Removed old silc_ske_verify_public_key function.
4733 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4736 silc_pkcs_private_key[_data]_set.
4738 * Made the password and public authentication more cleaner in
4739 server's protocol.c.
4741 * Removed historic and obsolete protocol `channel_auth' from
4742 both client and server.
4744 * Removed wrong way of sending command status messages from
4745 server to client in server's command.c. The old way violated
4746 protocol specification.
4748 Changes to silccore/silccommand.[ch]: removed
4749 silc_command_encode_status_payload -> not needed anymore,
4750 changed silc_command_encode_payload_va to accept extra
4751 argument on variable argument list. The argument type must
4752 now be provided to the function. Also, added new function:
4753 silc_command_encode_reply_payload_va which is same as
4754 normal command_encode_payload_va except command status type
4755 is provided as extra argument.
4757 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Added ~./silc directory handling. The directory includes the
4760 public and private keys for the client.
4762 Added silc_client_check_silc_dir, silc_client_create_identifier
4763 and silc_client_load_keys.
4765 * Implemented SILC protocol compliant public key. Added public
4766 and private key saving to and loading from files.
4768 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4769 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4770 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4771 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4772 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4774 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4775 silc_pkcs_load_[public/private]_key.
4777 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added silc_server_get_route (route.[ch]) to get connection
4780 data for the fastest route for given ID.
4782 * Implemented INVITE command on client and server. The command
4783 were re-defined in the SILC Protocol Specification and the
4784 implementation now complies with the specification.
4786 * Implemented PING command on client and server.
4788 * Implemented NAMES command on client and server. The server side
4789 supports currently only normal server not router server yet.
4790 Some changes to NAMES definition in SILC protocol specification.
4792 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Implemented LEAVE command on client and server.
4796 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4797 again. This change was made to the protocol as well. Server
4798 should not violate the protocol specification anymore.
4800 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4803 was tested. SOCKS4 was not but should work anyway.
