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 * Fixed buffer overflow from Irssi SILC Client. Affected
8 file irssi/src/fe-common/core/themes.c.
10 * Fixed double free in client library in the file
11 lib/silcclient/client.c when disconnecting from server.
13 * Applied double free patch from cras to Irssi SILC client.
14 Affected files irssi/src/core/[modules/expandos].c
16 * Fixed the disconnection handling to Irssi SILC Client.
17 The application must call silc_client_close_connection
18 in ops->connect client operation in case of failure of
19 the connection. Affected file is
20 irssi/src/silc/core/client_ops.c.
22 * Do not set sock->protocol to NULL in the function
23 silc_client_close_connection after executing the protocol's
24 final callback since the sock might not be valid anymore.
25 Affected file lib/silcclient/client.c.
27 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
29 * Do not enable SILC_THREADS if the linking with libpthread
30 did not happen. Affected file configure.in.pre.
32 * Added notion to protocol specification that server must
33 verify the sent authentication payload with CMODE when
34 setting the channel founder key. Implemented it to the
35 server. Affected file silcd/command.c.
37 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Added _EXTRA_DIST SILC distribution variable to the
40 distributions file. It is used to conditionally add extra
41 files or directories to the specific distribution. Affected
42 files ./prepare, Makefile.am.pre and distributions.
44 Removed the `_' from the start of the distribution names.
47 * Added README.WIN32 for instructions to compile the Toolkit
50 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
52 * Fixed a double free in disconnection in the server. Affected
53 file is silcd/server.c.
55 * Fixed the lib/silcske/groups.c to work now also with GMP
56 MP library. The string conversion did not work when using
57 specific base and the base is indicated in the string as well.
59 * Created win32/ directory which now includes MSVC++ specific
60 stuff so that toolkit (DLLs) may be compiled with MSVC++.
61 It will appear only in the toolkit distribution
63 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
65 * Changed the key material distribution function in case when
66 the hash output is too short. The data is now concatenated
67 a bit differently than it used to. Made the change to the
68 SKE protocol specification.
70 * Added better GMP detection to configure.in.pre. A patch
73 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed a minor bug in SKE that might cause some problem on
76 some platforms. Affected file lib/silcske/silcske.c.
78 * Added the cookie checking for initiator in the SKE. It checks
79 that the responder returns the sent cookie unmodified. The
80 affected file is lib/silcske/silcske.c. Added new SKE
81 error type INVALID_COOKIE that can be sent during the
82 negotiation. Fixed some memory leaks as well.
84 * Added the "invalid cookie" error message to Irssi SILC client's
87 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
89 * Added `task_max' field to the SilcClientParams to indicate
90 the maximum tasks the scheduler can handle. If set to zero,
91 default values are used. Affected file lib/silcclient/silcapi.h.
93 * Fixed memory leaks in silc_client_close_connection. Affected
94 file lib/silcclient/client.c.
96 * Added silc_client_del_client_entry to client library to free
97 all memory of given client entry. Affected file is
98 lib/silcclient/idlist.[ch].
100 * Added new functions silc_client_del_channel and
101 silc_client_del_server to delete channel and server entries.
102 Affected file lib/silcclient/[silcapi.h/idlist.c].
104 * Removed silc_client_del_client_by_id from silcapi.h.
106 * Fixed the INFO command to return the server's own info
107 correctly when querying by Server ID. Affected file is
110 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
112 * Removed the non-blocking settings in WIN32 code in the
113 silc_sock_[read/write] and added SleepEx instead. Affected
114 file lib/silcutil/win32/silcwin32sockconn.c. The availability
115 of input data is now checked with FIONREAD and ioctlsocket.
117 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Call silc_schedule_task_del_by_context in the
120 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
121 Affected file lib/silccore/silcprotocol.c.
123 * Call silc_protocol_cancel for active protocols in the
124 silc_server_close_connection if the funtion
125 silc_server_free_sock_user_data has not been called.
126 Affected file silcd/server.c.
128 * Generic tasks cannot be deleted using the del_by_fd
129 task deleting function since generic tasks does not match
130 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
132 * Added a notion to SILCOPER help file that the SILCOPER works
133 only on router server, not on normal server.
135 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Added for WIN32 support for the new scheduler as well.
138 Affected file lib/silcutil/win32/silcwin32schedule.c.
140 * Fixed the SHA1 implementation to work on various platforms.
142 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
144 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
145 API. It is part of the scheduler now. Everything else is
146 as previously but some functions has changed their names.
147 Checkout the lib/silcutil/silcschedule.h for the interface.
148 Updated all applications to use the new interface. Affected
149 files are lib/silcutil/silcschedule.[ch].
151 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
153 * Found a bug in the SKE implementation. The HASH value,
154 specified by the protocol, was not computed correctly. The
155 public key of the responder was not added to the computation
156 even though it is mandatory. Affected file lib/silcske/silcske.c.
157 This unfortunately causes incompatibilities with older
160 * Added WIN32 specific network init and uninit functions:
161 silc_net_win32_init and silc_net_win32_uninit to init and uninit
162 the Winsock2. Affected file lib/silcutil/silcnet.h and
163 lib/silcutil/win32/silcwin32net.c.
165 * Set the socket always to nonblocking mode on WIN32 after
166 reading data or writing data. Affected file is
167 lib/silcutil/win32/silcwin32sockconn.c.
169 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
171 * Fixed various compilation problems under WIN32. Affected
172 files lib/silcutil/win32/silcwin32thread.c and
173 lib/silcutil/win32/silcwin32schedule.c.
175 * Removed all _internal.h #includes from public header
176 files. Internal headers must never be included from
179 Removed also the lib/silcske/payload_internal.h file.
181 * All include files that may be needed (public and some others
182 included by the public headers) by application developers are
183 now copied to the ./includes directory. It does not copy any
184 internal headers. Affected file Makefile.defines.pre and all
185 Makefile.am's under lib/ and subdirs.
187 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
189 * Do not change the ~/.silc directory's permissions automatically.
190 Affected file irssi/src/silc/core/clientutil.c.
192 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
194 * Do not cancel the protocol in silc_server_close_connection
195 it might cause recursion. Now cancelled in the function
196 silc_server_free_sock_user_data. Affected file silcd/server.c.
198 * Fixed the silc_server_remove_clients_by_server to regenerate
199 the channel keys correctly finally. Added also new function
200 silc_server_remove_clients_channels to actually do it.
201 Affected file silcd/server.c.
203 * Fixed the silc_server_new_channel to not crash by giving
204 wrong router to the new channel. Affected file is
205 silcd/packet_receive.c.
207 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
209 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
210 which is given as argument to the silc_client_alloc now.
211 It can be used to configure the client and set various parameters
212 that affect the function of the client.
214 * The USERS command in server did not check whether the channel
215 is private or secret. Affected file silcd/command.c.
217 * Added new argument to the USERS command in protocol specification.
218 The USERS command now can take the channel name as argument
219 as well. Added support for this in client and server and
220 updated the protocol specs.
222 * Completed the GETKEY command in client. It can be now used
223 to fetch also servers public key not only some clients.
224 Affected files lib/silcclient/command[_reply].c.
226 * Added silc_client_get_server to return server entry by the
227 server name. Affected files lib/silcclient/silcapi.h and
230 * Redefined the IDENTIFY command in protocol specification to be
231 more generic. It now can be used to query information about
232 any entity in the SILC Network, including clients, servers and
233 channels. The query may be based either the entity's name
234 or the ID. Added support for this in both client and server.
236 Affected files silcd/command.c and lib/silcclient/command.c
239 * Optimized the WHOIS and WHOWAS commands in the server. Removed
240 the _from_client and _from_server functions. Affected file
243 * Added silc_client_get_channel_by_id_resolve to the file
244 lib/silcclient/silcapi.h to resolve channel information by
245 its ID. Added also silc_client_get_channel_by_id that
246 does not resolve it from the server.
248 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
250 * Added SilcServerEntry context into the client library
251 to represent one server. The INFO command now allocates
252 these to save the resolved server info. For now on the
253 client library will also keep information about servers,
254 connected and resolved with INFO.
256 The INFO command now allocates the SilcServerEntry context
257 and saves the server info there. The COMMAND_REPLY in
258 the INFO now returns the parameters to application in
259 same order as defined in the protocol specification.
261 The entries are cached in the client->server_cache.
263 * The INFO command is now issued after received the Client ID
264 from the server. Affected file lib/silcclient/client.c.
266 * The CMODE_CHANGE notify may now return also an SilcServerEntry
267 to the application as the mode changer might be server.
268 It is guaranteed that NULL is not returned anymore to the
269 application. Affected file lib/silcclient/client_notify.c.
271 The ID Type is now also passed to the application so that
272 it can check whether the returned entry is SilcClientEntry
275 Added new function silc_client_get_server_by_id to return
276 the server entry by ID. Affected files are the
277 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
279 * Do not create the channel in the Irssi SILC Client when issuing
280 the JOIN command but when received the sucessful JOIN command
281 reply. Otherwise the channel might get created even though we
282 could not join it. The Affected file is
283 irssi/src/silc/core/[silc-channels.c/client_ops.c].
285 * Fixed a channel joining bug in router. The router must also
286 check the channel modes, invite and ban lists etc. when serving
287 the JOIN command sent by normal server. Affected file is
288 silcd/command.c. The router now resolves the client's
289 information from the server who sent the JOIN command if it
290 does not know it, and processes the JOIN command only after
293 * Changed the SilcCommandCb to take new argument; void *context2.
294 Affected file lib/silccore/silccommand.h
296 The second argument in the command callbacks in the server now
297 includes the SilcServerCommandReplyContext if the command was
298 called as pending command callback from the command reply.
299 Otherwise it is NULL. When called as pending the status of the
300 command reply will be checked and if it was erronous the
301 error will be sent to the original sender of the command.
302 This way the client always receives the error messages even
303 though the server was actually the one who received the error
304 when it resent the command to router, for example. Affected
305 files silcd/command[_reply].[ch].
307 * Fixed sending WHOWAS command's error message to client if
308 the requested client could not be found. It was missing.
311 * Changed the CMODE and CUMODE commands reply arguments in the
312 protocol specification. The Channel ID is now sent in both
313 of the commands to identify the channel. Implemented this
314 new feature to the client and server. Affected files
315 lib/silcclient/command_reply.c and silcd/command.c.
317 * Made better checks for invite and ban lists in the JOIN
318 command in server. Affected file silcd/command.c.
320 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
322 * The server now performs the incoming host IP/DNS lookup
323 using the silc_socket_host_lookup and thus does not block
324 the server anymore. Affected file silcd/server.c.
326 * Completed the multi-thread support for SILC Scheduler in
327 the lib/silcutil/silcschedule.c.
329 * Fixed the configure.in.pre to detect the pthread correctly
332 * Fixed a deadlock in silc_task_queue_wakeup in the file
333 lib/silcutil/silctask.c.
335 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Added new function silc_schedule_wakeup that is used in
338 multi-threaded environment to wakeup the main thread's
339 schduler. It needs to be used when a thread adds a new task
340 or removes a task from task queues. After waking up, the
341 scheduler will detect the task queue changes. If threads
342 support is not compiled in this function has no effect.
343 Implemented the wakeup mechanism to both Unix and WIN32
344 systems. Affected files are lib/silcutil/silcschedule.[ch],
345 lib/silcutil/unix/silcunixschedule.c and the
346 lib/silcutil/win32/silcwin32schedule.c.
348 * Added new function silc_task_queue_wakeup to wakeup the
349 scheduler by the specified task queue. Affected file
350 lib/silcutil/silctask.[ch].
352 * The silc_socket_host_lookup_start now wakes up the scheduler
353 after adding the timeout task. Affected file is
354 lib/silcutil/silcsockconn.c.
356 * The silc_socket_host_lookup is synchronous now if the threads
357 support is not compiled in. However, the callback is still
358 called asyncronously through the scheduler, anyway. Affected
359 file lib/silcutil/silcsockconn.c.
361 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Added new function silc_socket_host_lookup to perform
364 asynchronous IP and FQDN lookups for the socket connection.
365 Affected files lib/silcutil/silcsockconn.[ch].
367 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Added SILC_MUTEX_DEFINE to define the mutex on environments
370 that may or may not compile the mutex support in.
372 Changed the silc_mutex_alloc interface. It allocates the
373 mutex now to the sent pointer and returns TRUE or FALSE.
375 Affected file lib/silcutil/silcmutex.h.
377 * Wrote the SILC Task Queue interface to support multi-threads.
378 Affected file lib/silcutil/silctask.[ch].
380 * Wrote the SILC Scheduler to support multi-threads. Affected
381 file lib/silcutil/silcschedule.c.
383 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
385 * Implemented the SILC Mutex API and SILC Thread API for WIN32
386 in lib/silcutil/win32/.
388 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
390 * Defined SILC Mutex API and SILC Thread API and implemented
391 them for Unix. Affected files are
392 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
393 lib/silcutil/unix/silcunixmutex.c and
394 lib/silcutil/unix/silcunixthread.c.
396 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
398 * Fixed the silc_server_remove_clients_by_server's channel
399 key re-generation. The hash table handling was incorrect
400 and would not work with many channels. Affected file is
403 * Fixed some memory leaks around the server code.
405 * Rewrote the silc_server_get_users_on_channel to support IPv6
406 based Client ID's. Affected file silcd/server.c.
408 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
409 specification. However, a separate document must be written
410 to define the detailed signing procedure and the payload
411 associated with the flag. Defined the flag to the
412 lib/silccore/silcchannel.h as well.
414 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
416 * Changed the dynamic tables to static size tables in the
417 lib/silccrypt/silchmac.c.
419 * Removed GCC dependencies from the code. A patch by cras.
421 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
423 * Do not show the error "Error receiving packet bla bla"
424 in server if it really was not an error (-2 means that reading
425 is pending). Affected file silcd/server.c.
427 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Fixed a possible crash in silc_server_remove_clients_by_server
430 in silcd/server.c. Fixed there also some memory leaks.
432 * Fixed the silc_idlist_replace_client_id. It could replace
433 wrong key in the hash table. Affected file silcd/idlist.c.
435 * Do not check whether there are global users on the channel
436 if the channel->global_users is FALSE. Affected functions
437 silc_server_remove_from_one_channel and
438 silc_server_remove_from_channels in silcd/server.c. Also,
439 do not check if the removed client is local as we can be
440 sure that global client was not removed from the channel
441 and checking for global users is not needed.
443 * The silc_server_remove_clients_by_server now re-generates
444 the channel keys correctly for those channels that had
445 clients removed from them. Affected file silcd/server.c.
447 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
449 * Found the reason of random crashes in the server. We weren't
450 ignoring the SIGPIPE signal (which can be sent in write())
451 and it crashed the server. Affected file silcd/silcd.c.
453 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
455 * Assure that sock->user_data is not NULL in the function
456 silc_server_packet_send in silcd/packet_send.c.
458 * Disconnect the remote connection if it could not be added
459 to any ID lists in the server. The affected file is
462 * Check in silc_server_packet_send[_real/dest] that the
463 socket is not disconnecting and ignore the data if it is.
464 Affected file silcd/packet_send.c.
466 * Define inline to __inline on native WIN32 compilation.
467 Affected file includes/silcwin32.h.
469 * Added some explicit type casts for inline code since MSVC
470 require them. Affected files lib/silcutil/silcbuffer.h,
471 lib/trq/silcdlist.h and lib/trq/silclist.h.
473 * Print warning in log files from now on if the packet
474 decryption fails. Affected file silcd/server.c.
476 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
478 * Changed the `say' client operation's interface to accept
479 new `type' argument to indicate the type of the message sent
480 by the library. The application may filter the library's
481 messages according the type. The affected file is the
482 lib/silcclient/silcapi.h.
484 * Added two new functions to lib/silcclient/silcapi.h:
485 silc_client_del_client and silc_client_del_client_by_id.
486 Affected file lib/silcclient/idlist.c.
488 * Moved the clientincludes.h from includes/ to silc/ and
489 serverincludes.h from includes/ to silcd/.
491 * The modes for the CMODE and CUMODE are now passed as
492 uint32 for application with COMMAND_REPLY. The affected
493 file is lib/silcclient/command_reply.c.
495 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
497 * /WHOIS without arguments shows client's own information.
498 Affected file lib/silcclient/command.c.
500 * Changed PING to not accept any arguments. The specs
501 says that client can ping only the connected server so
502 requiring an argument is not needed. Affected file is
503 lib/silcclient/command.c.
505 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Fixed a fatal bug in private message sending and reception
508 encryption and decryption when using private message keys.
509 The implementation was incorrect and did not follow the
510 specification. It causd that some of the message were
511 lost since it did not use the sending and receiving keys
512 as the protocol suggests. This has been fixed and will cause
513 incompatibilities with older clients when sending private
514 message encrypted with private message keys. Affected files
515 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
516 and various other in Irssi SILC Client.
518 Added `responder' boolean argument to the functions
519 silc_client_add_private_message_key[_ske] to indicate when
520 the key is added as responder or initiator of the key
523 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Removed the silc_ske_check_version function and created
526 a SilcSKECheckVersion callback. Added also a function
527 silc_ske_set_callbacks that is now used to set all SKE
528 callbacks. The callback functions are not given to
529 the SKE functions anymore, but this function is used to
532 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
534 * Added `silc_version' argument to the silc_client_alloc
535 to define the version of the application for the library.
536 The library will use the version string to compare it
537 against the remote host's (usually a server) version
538 string. Affected file lib/silcclient/silcapi.h
540 * Added the KE protocol context to Key Agreement context
541 in client library so that we can abort the SKE if it
542 is in process when we get timeout. Affected file is
543 lib/silcclient/client_keyagr.c.
545 * Do not resolve the client ID forever if it returns in the
546 first time that such client does not exist. This was done
547 for example with private message. Affected file is
548 lib/silcclient/client_prvmsg.c.
550 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
552 * Do not add regex.h for WIN32. The affected file
553 includes/silcincludes.h.
555 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
556 not work yet 100%. It generates the DLL's automatically
557 when compiling with --with-win32 under cygwin.
559 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
561 * lib/contrib/regex.c is not compiled on WIN32.
563 * Added silc_net_get_socket_opt function to the
564 lib/silcutil/silcnet.h.
566 * Added includes/silcwin32.h for WIN32 specific includes
569 * Do not use ptime structure or any of the posix process
570 functions on WIN32 in lib/silccrypt/silrng.c.
572 * Added silc_gettimeofday to provide generic function
573 for struct timeval on all platforms. Added the function
574 to lib/silcutil/silcutil.h.
576 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
578 * Moved the lib/silccore/silcsockconn.[ch] to the utility
579 library as they clearly belong there. As a plus side we
580 can make the actual socket connection routines platform
583 Added also new generic function silc_socket_read and
584 silc_socket_write (that used to be silc_packet_[read/write].
585 The implementation of these are platform specific.
587 * Added WIN32 specific routines of silc_socket_[read/write]
588 to lib/silcutil/win32/silcwin32sockconn.c.
590 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Added preliminary support for native WIN32 compilation under
593 cygwin (using the -mno-cygwin option for GCC) to the
594 ./configure.in.pre. The --with-win32 now prepares the
595 compilation for native WIN32.
597 * Rewrote the SILC Scheduler interface in the file
598 lib/silcutil/silcschedule.h. The scheduler is now context
599 based and does not have anymore any global static scheduler.
600 Moved the Unix scheduler to the lib/silcutil/unix/ directory
601 and created lib/silcutil/win32 directory for WIN32 based
604 * Added Unix specific network routines to the
605 lib/silcutil/unix/silcunixnet.c and the old
606 lib/silcutil/silcnet.c includes now only generic routines.
608 Added WIN32 specific network routines to the
609 lib/silcutil/win32/silcwin32net.c.
611 * Added Unix specific utility functions from the
612 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
614 * Added WIN32 SILC Scheduler to the file
615 lib/silcutil/win32/silcwin32schedule.c. The code is of course
618 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Do not handle JOIN notify in the server if the target client
621 is not registered (idata->registered == FALSE). The affected
622 file is silcd/packet_receive.c.
624 * Update the nickrec->founder in event_cumode in the Irssi SILC
625 client. Affected file irssi/src/silc/core/silc-channels.c.
627 * Fixed the CUMODE_CHANGE notify handling in the server when
628 server and router are announcing their clients on channels.
629 Now the mode changes are saved and notified correctly. The
630 affected file is /silcd/packet_receive.c.
632 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
633 They really did not replace the cache entry in the ID Cache.
634 Now they do that. Affected file silcd/idlist.c.
636 * Fixed the KICK notify handling in the Irssi SILC client to
637 update the channel records so that the kicked client does not
638 appear to be on the channel. The affected file is
639 irssi/src/silc/core/silc-channels.c.
641 * Always update the conn->current_channel when executing command
642 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
644 * Fixed the KILL notify handling in Irssi SILC client to remove
645 the killed client on all channels.
647 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Fixed the silc_parse_command_line to remove extra spaces
650 from the start and end of the arguments. Affected file is
651 lib/silcutil/silcutil.c.
653 * Cancel and free any active protocol in the function
654 silc_server_close_connection. Affected file silcd/server.c.
656 * Cancel and free any active protocol in the function
657 silc_client_close_connction. Affected file is
658 lib/silcclient/client.c.
660 * Do not execute the KILL command for clients that are in
661 history (ie. they are not in the network). Affected file is
664 * Fixed KILL notify handling, client does not crash anymore.
665 Affected file irssi/src/silc/core/silc-channels.c.
667 * Reduced the default packet buffer size from 2048 to 1024 in
668 lib/silccore/silcpacket.c.
670 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
671 counter to the SKE context that is incresed when the SKE library
672 performs async operation outside the library. If the outside
673 process frees the SKE context and FREED status will be set
674 and the library will detect after the sync operation that the
675 libary is freed. The affected files are
676 lib/silcske/silcske[_status].[ch].
678 * Resolve the client entry information in the function
679 silc_client_channel_message to assure that NULL pointer is not
680 passed as client entry to the application. */
682 * Fixed the task timeout calculation to assure that there is
683 never negative timeouts. The affected file is
684 lib/silcutil/silcschedule.c.
686 * Fixed the channel user mode notification sending in server.
687 It was sent point-to-point to the router (or to server by router)
688 but it needs to be destined to a channel. The routines now
689 supports sending the channel user mode notifys to the channels
690 when announcing clients and channels. Affected files are
691 silcd/server.c and silcd/packet_receive.c.
693 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
694 It did not actually replace the old channel entry in the cache.
695 Affected file lib/silcclient/client_notify.c.
697 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Fixed a possible crash in silc_packet_send_prepare. It now
700 assures always that there is enough space in the buffer and
701 at the tail area of the buffer (for MAC).
703 Fixed the inbound buffer reallocation in silc_packet_read.
704 It was old code and did not handle the reallocation correctly.
707 The affected file is lib/silccore/silcpacket.c.
709 * Fixed buffer overflow in silc_parse_nickname in the file
710 lib/silcutil/silcutil.c.
712 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * make install generates new server keys only if there is not
717 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
720 Added check that if the NOREPLY is set then we will not send
721 the away message. This avoids infinite loop of away messages
722 if both clients are away. The affected file is
723 lib/silcclient/client_prvmsg.c.
725 * Fixed client crash if /NICK was given without arguments.
726 Affected file lib/silcclient/command.c.
728 * Server does not send the invite list in INVITE command back
729 to the client if the list was not altered. Added this notion
730 to the protocol spec as well. Affected file silcd/command.c.
732 Fixed possible crash in INVITE command by checking the
733 value of silc_server_get_client_route command.
735 * Fixed the INVITE notify type handling. The arguments are now
736 taken in correct order and client does not crash. The affected
737 file is irssi/src/silc/core/silc-channels.c.
739 Removed the "Inviting xxx to channel" message from the
740 client library away and let the application handle it.
741 Affected file lib/silcclient/command.c. Added that message
742 to Irssi SILC client's message formats.
744 * Fixed CMODE command crash in client. It now checks the
745 amount of arguments correctly and does not crash. The affected
746 file is lib/silcclient/command.c.
748 * Do not create new channel automatically in silc_channels_join
749 but check whether the channel by that name already exists.
750 Affected file irssi/silc/core/silc-channels.c.
752 * Do not send the SERVER_SIGNOFF to router if the disconnected
753 entity was the router. Affected file silcd/server.c.
755 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
756 SILC client as it was missing from there.
758 Added the handling of the KICK notify to the Irssi SILC client
759 as it was missing. Added "you have been kicked" message to
760 Irssi SILC client's message modules formats.
762 Added the handing of the KILL notify to the Irssi SILC client
763 as it was missing. Added the kill message module formats
766 The affected file is irssi/src/silc/core/silc-channels.c.
768 * The router did not save the channel mode the server announced.
769 Affected file silcd/packet_receive.c.
771 * Fixed a possible crash in INFO command in server. If the
772 server did not provide the server info it crashed. Affected
773 file silcd/command.c.
775 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Fixed the GETKEY command in the server to check also the
778 global list. Otherwise the GETKEY would not work correctly
779 in normal SILC server. Affected file silcd/command.c.
781 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
783 * Fixed GETKEY crash, it crashed if the command did not succseed.
785 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
788 is now real and not just an macro interface to GMP.
790 Removed the entire GMP from the source tree and imported new
791 NSS MPI library instead. Reason for removing GMP is that it is
792 extremely large and compiles extremely slow. The NSS MPI
793 is only a few files and compiles in less than 10 seconds.
794 The speed is also about the same as GMP. The MPI is imported
797 If the system has GMP installed we will still use the GMP.
798 If it is not then the NSS MPI will be compiled.
800 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Merged a long nickname (127 characters long) crash bugfix from
803 Irssi CVS tree. Affected file irssi/src/core/misc.c.
805 * Merged a freed memory reference bugfix from Irssi CVS tree.
806 Affected file irssi/src/core/commands.c.
808 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * Added the server's public key sving and verification to the
811 server when performing the SKE. This was missing and the
812 remote server's (or router's) public key was accepted without
813 checking whether we have it previously or trust it at all.
814 Affected file silcd/protocol.c.
816 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Check in the silc_server_timeout_remote if protocol is active
819 and make sure that the protocol's final callback is called so
820 that all memory if freed. Affected file silcd/server.c.
822 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * silc_server_whois_send_reply crashed the server if the nickname
825 was 127 characters long. Affected file silcd/command.c.
827 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Added sanity check to the silc_server_new_client. If the hostname
830 is provided inside username then check that the provided hostname
831 really is the same as the resolved one. If the hostname was not
832 resolved then check it from the public key. Affected file is
833 silcd/packet_receive.c.
835 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
836 if the server disconnected us and the connection is not valid
837 anymore. Affected file irssi/src/silc/core/silc-channels.c.
839 * Moved the silc_client_[chmode|chumode|chumode_char] away from
840 the library to the lib/silcutil/silcutil.[ch].
842 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Close log file after open. Affected file
845 lib/silcutil/silclog.c.
847 * Check whether sock == NULL in silc_client_send_packet and return
848 if it is. Affected file lib/silcclient/silcclient.c.
850 * Check rec->entry == NULL in the Irssi SILC Client before
851 sending the channel message. Affecte file is
852 irssi/src/silc/core/silc-servers.c.
854 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Merged a splitted window bugfix from Irssi CVS tree. The
857 affected file is irssi/src/fe-text/textbuffer-view.c.
859 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
860 It did not print nickname.
862 * Improved the distributions system a bit.
864 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
867 irssi/src/fe-text/gui-window.c.
869 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
870 to in-active server. The affected file is
871 irssi/src/silc/core/client_ops.c.
873 * Resolve the client in USERS command reply if the entry does
874 not have username resolved. The affected file is
875 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
876 command to WHOIS command to really resolve stuff. The USERS
877 is not used any more in any critical section so WHOIS can
878 be used even though it might be slower than IDENTIFY.
880 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
883 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Changed the protocol API a bit more consistent in the
886 lib/silccore/silcprotocol.[ch].
888 * Changed the following headers to ROBODoc format:
890 lib/silccore/silcpayload.h
891 lib/silccore/silcprotocol.h
892 lib/silccore/silcsockconn.h
894 All core library headers are now formatted.
896 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Fixed a bug in Irssi SILC client; do not show that you are
899 server/router operator if you really are not. Affected file is
900 irssi/src/silc/core/client_ops.c.
902 * Renamed silc_command_free_payload to silc_command_payload_free.
903 Affected file lib/silccore/silccommand.h
905 * Added silcmath.h to include the prototoypes of various routines
906 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
909 * Changed the following headers to ROBODoc format:
911 lib/silccore/silcchannel.h
912 lib/silccore/silccommand.h
913 lib/silccore/silcid.h
914 lib/silccore/silcidcache.h
915 lib/silccore/silcmode.h
916 lib/silccore/silcnotify.h
917 lib/silccore/silcpacket.h
918 lib/silcmath/silcmath.h
920 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added checking to the server code not to start the server if
923 ciphers and stuff are not configured properly. Affected files
924 silcd/serverconfig.[h] and silcd/server.c.
926 * Changed the layout of the header files of the public interfaces
927 in the SILC libraries. The new layout supports ROBODoc
928 documentation tool (and some others) so that it is easy to create
929 a library reference manual. All the other headers and source
930 code must still follow the CodingStyle document. Also source
931 code must not include these ROBODoc stuffs, only the headers.
932 Furthermore, all public interface headers must now be named
933 by using `silc' prefix, example: silcapi.h, silccipher.h.
934 Some files were renamed due to this. All the other headers
935 must not be used as public interfaces. I will update the
936 CodingStyle document later. Changed following headers, so far:
938 lib/silcclient/silcapi.h
939 lib/silccore/silcauth.h
940 lib/silccore/silcprivate.h
941 lib/silccrypt/silcdh.h
943 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
947 * Removed silc_client_packet_send_flush from the client library
948 as it is not needed. Affected file lib/silcclient/client.[ch].
950 * Added printing of message of unresolved authentication method
951 to the Irssi SILC client. Added it to the module formats.
952 Removed the same message from the client library.
954 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Added new distribution feature, DISTLABEL. Every distribution
957 can define own preprocessor label that can be used in the
958 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
959 file distributions, acconfig.h.pre and prepare.
961 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * Added Makefile.defines_int to include the actual definitions
964 for Makefile.defines.in. Tested the new distribution system,
965 created distributions and tested installation.
967 * Added AWAY message printing to the Irssi SILC client. Added
968 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
970 * Added SCONNECT command to call the SILC's CONNECT command.
971 Cannot use CONNECT directly since Irssi uses that internally.
972 Affected file irssi/src/silc/core/silc-servers.c.
974 Added ACTION local command. It is same as ME command but takes
975 the channel as mandatory argument.
977 Rewrote some of the Irssi's help files to suite for SILC
980 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
982 * Added Makefile.defines[.in] that should for now on be included
983 in all Makefile.am file in the source tree. That file includes
984 all common compilation definitions for SILC source tree.
986 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Minor changes to the ./prepare script to change the package
989 name according the distribution name to the configure.in.
991 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Created new distribution system. Added file `distributions'
994 that defines all the distributions that can be created out of
995 the SILC source tree. The ./prepare script now reads that
996 file to determine how to prepare the distributions. The
997 first argument to the ./prepare is the name of the distribution
998 and second is the version of the distribution. If given
999 without arguments it creates the default (toolkit) distribution
1000 with the default version (defined in ./prepare).
1002 All Makefile.am files that are subject to the distributions
1003 are now named as Makefile.am.pre. These are ./Makefile.am
1004 and lib/Makefile.am. Others may be changed later.
1006 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1008 * Added invite list, ban list, some key management and connection
1009 error message printing to module formats in the Irssi SILC client.
1011 * Added new silc_client_set_away_message to set the away message
1012 that is back to the person who sent private message. The
1013 affected file lib/silcclient/silcapi.h and the
1014 lib/silcclient/client_prvmsg.c.
1016 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1018 * Fixed the private message sending in the Irssi SILC client,
1019 added local command KEY to the Irssi SILC client.
1021 Added key management and key agreement message formats to the
1022 irssi/src/fe-common/silc/module-formats.[ch].
1024 Added USERS (alias WHO) printing, server/router operator
1025 indication and LIST command printing to the module formats.
1027 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Fixed channel joining notify handling, cumode notify handling
1030 from Irssi SILC client.
1032 * Added SILC specific module-formats to the Irssi SILC client so
1033 that SILC specific message hilighting, colors etc is possible.
1034 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1036 Added channel mode, channel user mode, actions, notices,
1037 whois and whowas printing to the the module-formats.c.
1039 * Fixed a bug in channel deletion in the server. The channel
1040 is not left to the cache even if the channel founder auth mode
1041 is set when there are no users anymore on the channel. Affected
1042 file silcd/server.c.
1044 * The silc_net_localhost now resolves the entire hostname including
1045 the domain name. Affected file lib/silcutil/silcnet.c.
1047 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Changed the ask_passphrase client operation to be ascynchronous.
1050 It has now a completion callback and a context that the
1051 application must call after it has got the passphrase from
1052 the user. Affected files lib/silcclient/silcapi.h,
1053 lib/silcclient/protocol.c, lib/silcclient/command.c and
1056 Added SilcAskPassphrase callback that the application calls
1057 to deliver the passphrase to the library.
1059 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1060 The public key verification and especially a certificate
1061 verification is asynchronous procedure.
1063 Added new SILC_SKE_STATUS_PENDING status to indicate the
1064 request is pending and a callback will be called to finalize
1067 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1068 indicate that remote end did not send its public key (or
1069 certificate), even though we require it. Added check for this
1070 condition in the SKE. This was a security bug, now fixed.
1072 Defined new SilcSKEVerifyCbCompletion callback that is called
1073 when the verification process is completed.
1075 The affected files lib/silcske/silcske_status.h and
1076 lib/silcske/silcske.[ch].
1078 * Changed the verify_public_key client operation to be async
1079 as well. Defined SilcVerifyPublicKey callback that is used to
1080 indicate the success of the public key verification process.
1082 Changed the server and client to use the new async client
1085 * Changed the Irssi SILC client's internal scheduler to be called
1086 twice as many times as it used to be. As a result the client
1087 should be a bit faster now. Affected file is
1088 irssi/src/silc/core/silc-core.c.
1090 * Added support to Irssi SILC client of asynchronous public key
1091 verification and passphrase inquiry. Affected file is
1092 irssi/src/silc/core/silc-core.c.
1094 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Do not say "You have left channel %s" in client library.
1097 Moved it to the application. Affected files are
1098 lib/silcclient/command.c and silc/client_ops.c.
1100 * Fixed silc_client_get_clients. Command context was not
1101 duplicated and was freed memory in the callback. Affected
1102 file lib/silcclient/idlist.c.
1104 * Do not say "you are now talking..." on JOIN command in the
1105 client library. The appliation must handle it.
1107 * Do not say ".. changed topic to" in command reply in the
1108 client libary. The application must handle it.
1110 * Fixed TOPIC command sending in the client library.
1112 * Fixed a memory leak in silc_client_command_free in the file
1113 lib/silcclient/command.c.
1115 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Imported a modified version of Irssi client to the source tree.
1118 The Irssi will be used to create a new client called
1119 Irssi SILC. Imported to irssi/.
1121 Added silc_core_init_finish function to the Irssi. Affected
1122 file irssi/configure.in.
1124 A lot changes in the Makefile.ams around the irssi tree.
1126 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Do not rehash if the new size is same as the old size of the
1129 hash table, in the silc_hash_table_rehash*. The affected file
1130 lib/silcutil/silchashtable.c.
1132 * Replaced hash_table_del_by_context calls from the server
1133 (when channel->user_list and client->channels) to the
1134 hash_table_del as it is sufficient and faster.
1136 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * Added silc_hash_table_list, silc_hash_table_get and the
1139 SilcHashTableList structure to provide an alternative way to
1140 traverse the hash table. The affected files are
1141 lib/silcutil/silchashtable.[ch].
1143 * Changed the server's idlist routines to use the hash table
1144 routines to optimize the code.
1146 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Replaced the client entry's `channel' list and channel entry's
1149 `user_list' list to hash tables for optimized lookup. Changed
1150 the code to use the hash table interface around the code.
1151 Affected file lib/silcd/idlist.[ch].
1153 * Added `auto_rehash' boolean argument to the function
1154 silc_hash_table_alloc to indicate whether the hash table should
1155 auto-rehash when it thinks is appropriate time. It will
1156 increase the hash table size if the there is twice as much
1157 entries in the table than the size of the table, and will
1158 decrease the size if there are twice as less entries than
1159 the size of the table.
1161 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1165 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * silc_idcache_purge_by_context deletes the entry now by context
1168 as it is supposed to do. Affected file lib/silccore/idcache.c.
1170 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1171 client is not anymore valid (WHOWAS givens the info) and not
1172 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1174 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * Removed the `data' and `data_len' arguments from the ID Cache
1177 interfaces and added `name' argument. ID Cache does not handle
1178 anymore the binary data only a names associated with given ID.
1180 * When hashing a Client ID with silc_hash_id the entire ID is
1181 not hashed anymore, instead only the hash of the Client ID is
1182 hashed. This way we can access the Client ID from the cache
1183 with Client ID but with the hash of the ID (which is a hash of
1184 the nickname) as well without any difference in performance.
1186 Added also silc_idcache_find_by_id_one_ext to do one on one
1187 searching when we have the actual ID. Added also function
1188 silc_hash_client_id_compare. The affected files are
1189 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1191 * When hashing the name associated with a ID it is always done
1192 in lowercase. This way we can access the cache without worrying
1193 about case-sensitivity, even though, for example nicknames are
1196 * Fixed a bug in server with channel message sending. It put
1197 wrong ID type as destination ID. The affected file
1198 silcd/packet_send.c.
1200 * silc_idcache_del_by_context now deletes from all hash tables
1201 by context. Affected file lib/silccore/idcache.c.
1203 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Changed the client library to use the new ID Cache interface.
1206 Changes around the source tree.
1208 * Added silc_hash_table_rehash_ext to rehash with specific
1209 hash function. Affected file lib/silcutil/silchashtable.[ch].
1211 * Added silc_hash_string_compare to compare two strings in the
1212 hash table. Affected file lib/silcutil/silcutil.[ch].
1214 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1216 * Added new function silc_idcache_del_by_context into the
1217 lib/silccore/idcache.[ch].
1219 * Changed the server's ID list routines to use the new ID Cache
1220 interface. Changes around the source tree.
1222 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1224 * Added silc_hash_table_del[_by_context]_ext functions in to the
1225 lib/silcutil/silchashtable.[ch].
1227 Removed silc_hash_table_find_all* routines and added new
1228 silc_hash_table_find_foreach to replace them.
1230 Added silc_hash_table_replace_ext function as extended
1231 replacing function. Separated the simple hash table interface
1232 from the extended hash table interface in the file
1233 lib/silcutil/silchashtable.h.
1235 * Fixed minor bugs and changed it to use some of the new
1236 hash table functions in lib/silccore/idcache.c
1238 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Added new function silc_hash_table_find_all to return all keys
1241 in the hash table by the specified key. As the hash table is
1242 collision resistant it also makes it possible to have several
1243 duplicate keys in the hash table. This function may be used to
1244 find all of the keys from the hash.
1246 Added user_context arguments to the SilcHashFunction,
1247 SilcHashCompare and SilcHashDestructor to deliver user specified
1250 Added new fuctions silc_hash_table_find[_all]_ext to do
1251 extended lookup with specified hash and compare functions and
1252 specified user contexts.
1254 Added new function silc_hash_table_add_ext to add the key
1255 with specified hash function and user context.
1257 Added new function silc_hash_table_foreach to traverse all
1258 entrys in the hash table. Added SilcHashForeach callback
1261 Added new function silc_hash_table_del_by_context to delete
1262 the entry only if the context associated with the key matches.
1264 Affected files are lib/silcutil/silchashtable.[ch].
1266 * Removed silc_hash_[server/client/channel]_id and added just
1267 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1268 silc_hash_id_compare to compare two ID's using as the hash table
1269 comparison function. Added also silc_hash_data to hash
1270 binary data and silc_hash_data_compare to compare it.
1272 * Removed silc_idlist_find_client_by_hash as it is not needed
1273 anymore. Affected file silcd/idlist.[ch].
1275 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1276 to use internally the SilcHashTable. The new ID Cache is a lot
1277 faster than the old one. Some of the ID Cache interface was also
1278 rewritten and obsolete and stupid functions were removed.
1280 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Added entry_count field to the SilcHashTable to keep the number
1283 of the entries in the table. Implemented the function
1284 silc_hash_table_rehash. Added new function
1285 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1287 Fixed a minor bug in silc_hash_table_free.
1289 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1290 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1291 into the lib/silcutil/silcutil.[ch].
1293 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1295 * Implemented a collision resistant hash table into the
1296 lib/silcutil/silchashtable[ch]. See the header and the source
1297 for the SilcHashTable API.
1299 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Merged dotconf version 1.0.2 into lib/dotconf.
1303 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Do not compile anything in lib/silcsim/* if the SIM support
1306 is not enabled. The tree should now compile without problems
1309 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Compiled the SILC under cygwin. Compiled and tested briefly
1312 without problems. More tests needed. The SIMs didn't compile
1315 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1317 * Fixed possible crash in silc_get_username in the
1318 lib/silcutil/silcutil.c.
1320 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Fixed a va_arg in silc/client_ops.c.
1324 * Oops, RC5 routines were named AES and caused some problems
1325 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1327 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Added new SilcIDIP structure into the lib/silccore/id.h and
1330 replaced the old `ip' fields from all SILC ID's to that type.
1331 This is a step towards IPv6 support.
1333 The silc_id_get_len takes now the ID as an extra argument.
1334 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1335 both IPv4 and IPv6 based ID's.
1337 The affected files are lib/silccore/id.[ch] and other files
1338 around the tree using these routines.
1340 * Removed the ID length arguments in server from various
1341 silc_server_send_notify_* routines -> they are not needed
1344 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Fixed memory leak in silc_encode_pem_file in the file
1347 lib/silcutil/silcutil.c.
1349 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Check minor version as well in the SKE. Affected files are
1352 silcd/protocol.c and lib/silcclient/protocol.c.
1354 * Added --identifier option to the server so that an identifier
1355 can be when creating the public key for the server. Affected
1356 file is silcd/silcd.c.
1358 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1359 lib/silccrypt/silcpkcs.c.
1361 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Register default ciphers and stuff when using -C option with
1364 the server. Affected file sildc/silcd.c.
1366 * Put back the servers public key filename format, it is better
1367 than the new one. For now, the client keys are saved with the
1368 new filename format. The affected file silc/client_ops.c.
1370 * Implemented the Cipher API for the rest of the ciphers that
1371 did not implement it or implemented it the wrong way.
1373 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1375 * Register default ciphers and stuff when using the -S option
1376 in the client. Affected file silc/silc.c. Same also when
1377 creating new key pair with -C option.
1379 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Fixed the silc_verify_public_key client operation function to
1382 save the public keys differently. The fingerprint is now
1383 used as filename and not the hostname. This way also the
1384 client keys are saved uniquely and not with hostnames. The
1385 affected file is silc/client_ops.c.
1387 * Trimmed the silc_hash_fingerprint function to remove extra
1388 whitespaces from the end of the fingerprint. The affected
1389 file is lib/silccrypt/silchash.c.
1393 * Added silc_cipher_register_default function to register all
1394 default ciphers. It can be used when configuration files
1395 does not exist and the application does not want any specific
1396 ciphers in any specific order.
1398 The SilcDList is now used as silc_cipher_list dynamically
1399 allocated cipher list. Removed the static list all together
1400 and now all ciphers must be allocated to the dynamic list.
1401 The silc_cipher_alloc routine was changed to check only the
1404 All silc_cipher_* routines that used to return int returns
1407 The affected files lib/silccrypt/silccrypt.[ch].
1409 * The same thing was done to silc_hash_* as for silc_cipher_*
1410 routines. Affected files lib/silccrypt/silchash.[ch].
1412 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1413 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1414 Added also silc_pkcs_[un]register[_default] functions.
1415 Removed the data_context from the PKCS API.
1417 * Added silc_hmac_register_default function to register default
1418 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1419 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1420 to unregister all hmacs at once.
1422 * Register the default ciphers, hash functions, PKCSs and HMACs
1423 if client's configuration file does not exist. The affected
1426 * The client did not load the hash functions from the SIM
1427 modules at all. Added support for this. Affected file is
1428 silc/clientconfig.c.
1430 * When decoding public key with silc_pkcs_public_key_decode, check
1431 the supported algorithm only if PKCS are registered. Affected
1432 file lib/silccrypt/silcpkcs.c. The same was done with the
1433 silc_pkcs_private_key_decode.
1435 * Fixed the SILC List routines to keep the list always in order.
1436 It used to change the list's order when traversing the list but
1437 not it preserves the order. Affected file lib/trq/silclist.h.
1439 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1441 * Added the client library to use the SilcSocketConnection's
1442 reference counter (by silc_socket_dup) to prevent the bug that
1443 the socket object may be freed underneath async operation.
1445 * The name resolv library checking fixes in the configure.in.pre.
1448 * Created new version of the protocol drafts for future
1449 development. The -03 drafts are the ones that will be changed
1450 in the trunk now and the -02 will remain as they are.
1452 * Send list of CUMODE notifys to the router when announcing
1453 the channel users to the router. Affected file silcd/server.c.
1454 If the router receiving channel founder CUMODE for a channel
1455 that already has channel founder it will send CUMODE notify
1456 to the sender to remove the channel founder rights from the
1457 announced client. Affected file silcd/packet_receive.c.
1459 * The CUMODE notify may now use Server ID as well as the entity
1460 who changes the mode. Updated protocool specs.
1462 * Updated INSTALL and README files.
1464 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1466 * New web pages in the http://silc.pspt.fi. The pages was
1471 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Implemented the [DenyConnectin] config section in the server.
1474 Added silc_server_config_denied_conn to check whether incoming
1475 connection is denied. Affected file silcd/serverconfig.[ch].
1477 * Do not check the ports when checking the incoming configuration
1478 data if the port is 0, meaning any. Affected file is
1479 silcd/serverconfig.c.
1481 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Fixed buffer overflow in silc_string_compare in the file
1484 lib/silcutil/silcutil.c.
1486 * Fixed double free in silc_server_command_leave in the file
1489 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Fixed the version checking in the server. Affected file is
1494 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Fixed the configuration data fetching when accepting new
1497 connections in the server. Affected file silcd/server.c.
1499 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Added `sender_entry' argument to the function
1502 silc_server_packet_relay_to_channel so that we can check
1503 whether some destination actually belongs to the same route
1504 the sender belongs (ie, we must not resend the packet to the
1505 sender). Affected file silcd/packet_send.[ch].
1507 * Added `servername' field to the SilcClientEntry in the server
1508 to hold the name of the server where client is from. Affected
1509 file is silcd/idlist.h.
1511 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1513 * Moved the channel message encrypting in the router betwen
1514 router connections from silc_server_channel_message to the
1515 silc_server_packet_relay_to_channel since we want to check
1516 whether we have anybody channel before encrypting anything.
1517 Affected files silcd/packet_[receive/send].c.
1519 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Fixed the [AdminConnection] server config section to support
1522 multiple entries. Affected file silcd/serverconfig.c.
1524 * Added support into the server to check the validity of the
1525 incoming connection before executing any KE or authentication
1528 * The connection configuration is now saved to the KE and
1529 connection auth protocol contexts and not fetched anymore in
1530 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1532 * The local hosts listenning address and port is also resolved
1533 now when starting the server. We want to have the socket object
1534 to include the real address and port for the listener. Added
1535 new function silc_net_check_local_by_sock into the files
1536 lib/silcutil/silcnet.[ch].
1538 * Fixed a broadcast bug in server -> do not broadcast if we
1541 * Fixed a routing bug. Do not route broadcast packets ever.
1542 Broadcast packets must be processed always and not routed since
1543 they may be destined to some other host than yourself and thus
1544 would get routed without no good reason. Affected file is
1547 * Added function silc_server_config_is_primary_route to check
1548 whether primary router connection has been configured (a router
1549 configuration that we are initiating). If there is not, we
1550 will assume that there is only two routers in the SILC network
1551 and we will use the incoming router connection as our primary
1552 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1554 * Changed the order of the broadcasting. Broadcast _after_ the
1555 packet has been processed not before. Affected file is
1558 * Fixed a [ClientConnection] parsing bug. The port was never
1559 parsed correctly thus resulting to port 0. Affected file
1560 silcd/serverconfig.c.
1562 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1563 argument and did not set the broadcast packet flag. Affected
1564 file silcd/packet_send.c. Fixed same bug in the function
1565 silc_server_send_notify as well.
1567 * If we receive NEW_ID packet for our own ID in the server, ignore
1570 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Removed the nickname from the Private Message Payload.
1575 Updated the code and the protocol specs.
1577 * Updated protocol specs for submitting to the IETF.
1579 * Tweaked the Random Number Generator a bit. Affected file
1580 lib/silccrypt/silcrng.c. Exported a new function
1581 silc_rng_[global]_add_noise which can be used to add more
1584 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Do not parse packets with different timeout when protocol
1587 is active -> may cause problem with rekey. Affected file
1590 * When server receives signoff notify it must not create
1591 new channel key if the client is on any channels since the
1592 sender of the signoff notify will create it.
1594 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1596 * Added printing of error messages during SKE protocol from the
1597 failure packet sent by server during SKE. Affected file
1600 * Removed the client's failure_callback handling with timeout
1601 and handle it immediately when received.
1603 * The SKE library returned wrong type in SUCCESS and FAILURE
1604 packets. They must be 32 bit MSB not 16 bit MSB.
1606 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1608 * Ok, rewrote the logic of the re-key and now it seems to work.
1609 I tested it on high traffic with frequent re-keys without
1610 problems. Added hmac_receive (and renamed hmac to hmac_send)
1611 in SilcClientConnection in lib/silcclient/client.h and
1612 in SilcIDListData in silcd/idlist.h. Also, removed the
1613 SilcPacketParserContext's cipher and hmac fields as they are
1614 not needed anymore and actually caused some problems when
1615 the ciphers and hmac's changed underneath the packet parser.
1617 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1619 * If re-key protocol is active then process the incoming packets
1620 synchronously since we must assure that icoming packets encrypted
1621 with the old key is processed before the new keys is set to
1622 use. This is true other packets than for REKEY packets.
1623 Affected file silcd/server.c. The same was done to client library
1624 as well, affected file lib/silcclient/client.c.
1626 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Fixed bug in client and server to accept the force send if
1629 the packet is send from silc_[server/client]_packet_process
1630 function. Otherwise the packets are never delivered, oops.
1632 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Disable force sending of packets when REKEY protocol is active.
1635 We must assure that no packet is sent directly when rekey is
1636 performed. All packets must be sent through packet queue.
1637 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1638 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1639 function is silc_[server/client]_packet_send_real to check
1642 * Replaced the SIM paths from example config files to
1643 /usr/local/modules. Also, make install creates now
1644 /usr/local/silc/logs directory to hold all the SILC server
1647 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1658 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * When MAC computation fails the silc_packet_decrypt returned 0
1661 even though it was supposed to return -1. Fixed this. The
1662 affected file is lib/silccore/silcpacket.c.
1664 * Do not replace the config files in /etc/silc (in make install)
1665 if they already exist. Affected file ./Makefile.am.
1667 * Do not send re-key packets immediately but through packet queue.
1668 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1670 * Changed silc_net_check_host_by_sock to return FALSE if the
1671 IP/DNS could not be resolved. Though, it returns the IP address
1672 now even if it could not resolve it (but returns also FALSE).
1673 Affected file lib/silcutil/silcnet.[ch].
1675 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Added silc_pkcs_decode_identifier to decode the public key's
1678 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1679 Added also silc_pkcs_free_identifier. Added also new context
1680 SilcPublicKeyIdentifier.
1682 * Added -S option to the silc client. It is used to dump the
1683 contents of the specified public key file.
1685 * Changed the PKCS api to return the public key length when
1686 setting the public key.
1688 * Fixed a fatal bug in the public and private key file loading.
1689 Affected file lib/silccrypt/silcpkcs.c.
1691 * Execute the packet parsing for client with zero (0) timeout
1692 if the protocol is active. Affected file silcd/server.c.
1694 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Made the key generation options to the silcd program. Added
1697 -C option, equivalent to client's option.
1699 * Added new [ServerKeys] config section to the server. It
1700 configures the server's public and private key.
1702 * Defined generic Public Key Payload into the protocol
1703 specification to send specific type of public keys and
1706 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1707 public key or certificate.
1709 * Implemented the GETKEY command to the server and to the
1710 client library and on user interface.
1712 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Made preliminary `make install' work.
1716 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Added SilcServerRekey context into silcd/idlist.h.
1720 * Added the PFS support as defined in the specification to the
1721 SKE protocol. Affected files lib/silcske/*.c.
1723 * Added `ske_group' field to the SilcServerRekey context to hold
1724 the number of the SKE group that is used with PFS in re-key.
1725 Affected file silcd/idlist.h.
1727 * Added PFS re-key support to the server. Affected file is
1730 * Added silc_protocol_cancel to cancel execution of the next
1731 state of the protocol. Affected file is
1732 lib/silccore/silcprotocol.[ch].
1734 * Added the re-key support with and without PFS to the client
1735 library. Re-key is performed once in an hour, by default.
1737 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1738 Added silc_client_rekey_callback and silc_client_rekey_final.
1739 Affected files are lib/silcclient/protocol.[ch] and
1740 lib/silcclient/client.[ch].
1742 * Removed the `hmac_key' and `hmac_key_len' fields from the
1743 SilcClientConnection structure; not needed. Affected file is
1744 lib/silcclient/client.h.
1748 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Do not ask whether user wants to use the negotiated private key
1751 for private messages, just use it. Affected file is
1752 silc/local_command.c.
1754 * Added `send_enc_key' and `enc_key_len' fields to the
1755 SilcIDListData structure since they are needed in the re-key
1756 phase. Affected file is silcd/idlist.[ch].
1758 * Implemented the simple re-key protocol into the server.
1759 Affected files silcd/server.c and silcd/protocol.[ch]. The
1760 re-key will be performed once in an hour, by default.
1762 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1763 Added silc_server_rekey, silc_server_rekey_callback and
1764 silc_server_rekey_final.
1766 * Removed Tunneled flag from the protocol. Updated the code
1767 and the specifications.
1769 * Adde `pfs' field to the SilcIDListData to indicate whether
1770 the PFS is to be performed in the re-key. Affected file is
1773 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1776 int64 of at least the xintXX size. If void * is less that 4
1777 bytes uint32 * will be used. Defined bool as boolean.
1779 * Changed _ALL_ unsigned long and unsigned int to uint32,
1780 unsgined short to uint16 in the source tree.
1782 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1783 not handle clients that has entry->data.registered == FALSE.
1784 They are not in the network anymore. Affected file is
1787 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * Implemented the sending of the SERVER_SIGNOFF notify in the
1790 server. Affected file is silcd/server.c.
1792 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1793 Added also silc_notify_payload_encode_args into the
1794 lib/silccore/silcnotify.[ch].
1796 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1797 Affected file silcd/packet_receive.c.
1799 * Implemented the SERVER_SIGNOFF notify handling in the client
1800 library. Affected file lib/silcclient/client_notify.c. Also,
1801 implemnted the printing of the SERVER_SIGNOFF info to the
1802 application. Affected file silc/client_ops.c.
1804 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1805 if the deleting was successful. Affected file silcd/idlist.[ch].
1807 * Added support for public key authentication in the connection
1808 authentication protocol in the client library. Affected file
1809 lib/silcclient/protocol.c.
1811 * Changed the server's silc_idlist_get_clients_by_* interface
1812 to support already allocated array so that new entries may be
1813 added to pre-allocated array. Affected file silcd/idlist.[ch].
1814 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1815 and command replies.
1817 * All command reply functions in the server now calls the
1818 pending command callback even if error occured. This way the
1819 error will be delivered to the client as well. Affected files
1820 silcd/command.c and silcd/command_reply.c.
1822 * Fixed INFO command to return local server's info if no server
1823 was provided. Affected file lib/silcclient/command.c.
1825 * Removed RESTART command for good. Updated the code and the
1828 * Rewrote parts of the task system. It is a bit simpler now.
1829 Removed unsued task priorities. The affected files are
1830 lib/silcutil/silctask.[ch].
1832 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Moved the USERS printing from the library to the application.
1835 Affected files lib/silcclient/command.c and silc/client_ops.c.
1837 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Added channel key re-key support. The re-key is perfomed
1842 only by the router and is done once in an hour. Added `rekey'
1843 field to the SilcChannelEntry in the server. Affected files
1844 silcd/server.c and silcd/idlist.h.
1846 * Added silc_task_unregister_by_context into the file
1847 lib/silcutil/silctask.[ch].
1849 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Added SILC_UMODE_GONE mode to indicate when the client is not
1852 present in the SILC network. Added also support to the local
1853 command AWAY that will set this mode. Added support of showing
1854 "xxx is gone" in WHOIS command. The USERS command shows the
1855 gone status as well.
1857 * Fixed setting server and router operator privileges in the
1858 server's UMODE command. Affected file silcd/command.c.
1860 * Merged the SKE KE1 and KE2 payloads into one payload. The
1861 new KE payload is equivalent to the old KE2 payload.
1863 Cleaned up the SKE Start Payload parsing. It now uses the
1864 simple buffer unformatting to do the parsing. A lot faster
1867 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1868 to the SKE that is used to indicate whether both of the SKE
1869 parties should perform authentication. By default only the
1870 responder performs authentication. By setting this flag also
1871 the initiator must do authentication. By default it is unset
1872 since in normal SKE case, client to server connection, only
1873 the responder should do authentication. When doing SKE between
1874 two clients both should perform authentication. Updated the
1875 code and the protocol specs.
1877 * A little fix to IDENTIFY command in the server. Search the
1878 client first by hash not nickname. Affected file is
1881 * Fixed the silc_client_close_connection to support closing
1882 the client to client connections wihtout deleting too much
1883 data. Affected file lib/silcclient/client.c.
1885 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1886 are received if protocol used to be active but is not anymore
1887 the application would crash due to NULL pointer dereference.
1888 Affected files silcd/server.c and lib/silcclient/client.c.
1890 * Added `hash' field to the SilcClientConnection to include
1891 the hash function negotiated in the SKE protocol.
1893 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1894 to set the channel founder authentication data. A client can
1895 claim the founder rights later by providing the authentication
1896 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1897 This way the channel founder can regain the channel founder
1898 privileges even it is left the channel. This works only on
1899 local server and the client must be connected to the same
1900 server to be able to regain the founder rights. Updated the
1901 protocol specs accordingly.
1903 Added support to the CMODE command in the client to set the
1904 founder auth data. Read the README to see how to set it.
1906 Added support to the CUMODE command to claim the founder
1907 rights. Read the README to see how to do it.
1909 Added support for the founder authentication to the Channel
1910 Entry in the server. Affected file silcd/idlist.h.
1912 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1913 server's CMODE command. Affected file silcd/command.c.
1915 * Added the following new functions into lib/silccore/silcauth.[ch]:
1916 silc_auth_get_method and silc_auth_get_data.
1918 * The server now saves the remote hosts public key to the
1919 SilcIDListData pointer. Affected file silcd/protocol.c.
1921 * The normal server now does not remove the channel entry from
1922 the cache if the founder authentication data is set. It used
1923 to remove it if the founder was the last one on the channel on
1924 the server and left the channel. The auth data is saved and
1925 if the channel is re-joined later the old entry is used with
1926 the old auth data. Affected files silcd/command_reply.c and
1929 * Removed the `pkcs' field from the SilcIDListData structure
1930 in the server; it is not used. Affected file silcd/idlist.h.
1932 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * Fixed packet processing on slow links. Partial packets were
1935 never re-processed because the incoming data buffer was cleared
1936 by the application. Application must not directly clear the
1937 sock->inbuf, the packet processing routines handle it. Fixed
1938 this in client library and in server.
1940 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Fixed the WHOIS and IDENTIFY send reply function to really
1943 check whether to send list or just one entry. Affected file
1946 * Cleaned up the LEAVE command's channel key distribution. The
1947 affected file silcd/command.c.
1949 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1950 can enforce the channel mode as well. In that case the ID
1951 includes the ID of the server. The code now enforces the
1952 mode change if the router have different mode than the server.
1954 * The notify client operation with CMODE_CHANGE notify can now
1955 return NULL client_entry pointer if the CMODE was not changed
1956 by client. Application must check for this.
1958 * Added <Server ID> argument to INFO command to support server
1959 info fetching by Server ID.
1961 * Added silc_server_announce_get_channel_users to get assembled
1962 packets of channel users of the specified channel. Affected
1963 file silcd/server.[ch].
1965 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1966 was freed underneath the ID Cache.
1968 * Re-announce clients when the server received CHANNEL_CHANGE
1969 notify from the router. Affected file silcd/packet_send.c.
1971 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1974 crashed since it did not handle the fact that there is no cipher
1975 called "3" and didn't check the error condition. Now fixed.
1977 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1978 flag. It can be used to send message requests.
1980 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Implemented the RESTART command in the client.
1984 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1985 notice type messages. Added notice printing to the user
1988 * The channel keys are not re-generated if the channel's mode
1989 is PRIVKEY, ie private key on the channel exists. Affected
1990 files silcd/server.c and silcd/command.c.
1992 * Fixed a little bug in channel message delivery when channel
1993 private keys are set in the server. Affected file is
1994 silcd/packet_send.c.
1996 * Changed the setting on channel->on_channel = TRUE from the
1997 silc_client_save_channel_key to the JOIN command reply. The
1998 key payload is not received if the private channel key is set.
1999 Affected file lib/silcclient/command_reply.c and the
2000 lib/silcclient/client_channel.c.
2002 * When the CMODE_CHANGE notify is sent and the channel private
2003 key mode is removed the channel key must be re-generated in
2004 other cells as well. Added this support for the router in the
2005 silcd/packet_receive.c.
2007 * Added new local command NOTICE to send notice message on
2008 channel. Affected file silc/local_command.[ch].
2010 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2012 * Added new local command ME to the client. It is used to send
2013 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2014 some action. Affected file silc/local_command.[ch].
2016 * Changed channel_message and private_message client operations
2017 to deliver the message flags to the application. Added also
2018 the `flags' arguments to the silc_client_send_channel_message
2019 and silc_client_send_private_message functions. Affected file
2022 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Redefined the Private Message Payload to support private message
2025 keys and to support the new private message flags. Updated
2026 the protocol specs. Flags makes it possible to have for example
2027 CTCP style messages.
2029 * Added new type SilcPrivateMessagePayload and defined an API
2030 for it in the lib/silcclient/silcprivate.[ch].
2032 * Tested private message private keys successfully. Tested the
2033 private message key set, unset and list commands with the new
2036 * Redefined the Channel Message Payload to include the channel
2037 message flags (equal with private message flags) to support
2038 for example CTCP style messages.
2040 * Defined some of the message (for channel and private message)
2041 flags. Updated the protocol specs and added the flags to the
2042 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2044 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Added SilcKeyAgreementStatus type to the key agreement routines
2047 to indicate the current status and error if one occured.
2048 The status types are defined in the lib/silcclient/silcapi.h.
2050 * Added new local command KEY that is used to set and unset private
2051 keys for channels, set and unset private keys for private messages
2052 with remote clients and to send key agreement requests and
2053 negotiate the key agreement protocol with remote client. The
2054 key agreement is supported only to negotiate private message keys,
2055 it currently cannot be used to negotiate private keys for channels,
2056 as it is not convenient for that purpose.
2058 * Fixed a minor pending callback setting bug in the function
2059 silc_client_get_client_by_id_resolve, now the function works.
2060 Affected file lib/silcclient/idlist.c.
2062 * Added function silc_net_get_local_port to get local bound
2063 port by socket. Added to lib/silcutil/silcnet.[ch].
2065 * Added `sockets' and `sockets_count' fields to the SilcClient
2066 object. They hold the sockets of the listenning sockets in
2067 the client. Listenning sockets may be for example the key
2068 agreement server. Affected file lib/silcclient/client.[ch].
2069 Added functions the silc_client_add_socket and the
2070 silc_client_del_socket. They are exported to the application
2073 * Added ~./silc/clientkeys to support other client's public keys.
2075 * Renamed verify_server_key client operation to verify_public_key
2076 and added one argument to indicate the type of the connection
2077 (server, client etc.).
2079 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Added silc_server_connection_auth_request to handle the
2082 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2083 silcd/packet_receive.[ch].
2085 * Added silc_server_send_connection_auth_request into the
2086 silcd/packet_send.c to send the connection auth request packet.
2088 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2091 * Fixed the public key authentication in responder side in the
2092 server. The `auth_data' pointer includes the SilcPublicKey
2093 not the path to the public key. Affected file silcd/protocol.c.
2095 * Implemented the public key authentication in the initiator side
2096 in the server. Affected file silcd/protocol.c.
2098 * Removed the [RedirectClient] config section from the server
2099 configuration. Is not needed and I don't want to implement it.
2101 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Cleaned up the CMODE command in the server. It now works
2104 correctly and supports all the modes defined in the protocol.
2105 Affected file is silcd/command.c.
2107 * Added `hmac_name' field to the SilcChannelEntry in the server
2108 to hold the default HMAC of the channel. It can be set when
2109 creating the channel (with JOIN command). Affected files
2112 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2113 type to indicate the change of the current cipher and hmac
2114 on the channel. Client can safely ignore the <cipher> argument
2115 (if it chooses to do so) since the CHANNEL_KEY packet will
2116 force the channel key change anyway. The <hmac> argument is
2117 important since the client is responsible of setting the new
2118 HMAC and the hmac key into use.
2120 * Fixed the CMODE command in the client library as well.
2122 * Tested CMODE command in router environment successfully.
2124 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Show the version of the remote client (or server) when connecting
2127 to the server. It is logged to the log file. Affected file
2128 is silcd/protocol.c.
2130 * Fixed the KILLED notify handling in the client library. The
2131 client must be removed from all channels when receiving the
2134 Also, do not remove the client entry when giving the KILL
2135 command but when the KILLED notify is received.
2137 * Removed silc_idlist_find_client_by_nickname from the server.
2138 Not needed anymore. Affected files silcd/idlist.[ch].
2140 * Implemented the CHANNEL_CHANGE notify type handling to the
2141 server. Affected file silcd/server.c.
2145 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Added silc_server_send_notify_invite to send the INVITE
2148 notify between routers.
2150 * Implemented the INVITE command correctly to the server.
2152 * Implemented the INVITE notify type handling in the server.
2154 * Implemented the INVITE command to the client library and on the
2157 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2159 * Added function silc_server_get_client_resolve to find the
2160 client entry by ID from all ID lists and then resolve it
2161 (using WHOIS) if it cannot be found. Affected file is
2164 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Implemented the BAN command to the client library.
2168 * The JOIN command in the server now checks the invite list
2171 * Changed the silc_command_reply_payload_encode_va and the
2172 silc_command_payload_encode_va to support that if argument is
2173 NULL it ignores and checks the next argument. Affected file
2174 lib/silccore/silccommand.c.
2176 * Added silc_server_send_notify_ban to send the BAN notify
2177 type between routers.
2179 * Chaned the silc_notify_payload_encode to support that if
2180 argument is NULL it ignores and checks the next argument.
2181 Affected file lib/silccore/silcnotify.c.
2183 * Tested ban lists in router environment successfully.
2185 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Implemented BAN command to the server, in silcd/command.[ch].
2189 * Removed the BAN and INVITE_LIST modes from the CMODE command
2192 * Added function silc_string_match to regex match two strings.
2193 Affected files lib/silcutil/silcutil.[ch].
2195 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Redefined parts of the SilcChannelEntry in the server to support
2198 the new ban and invite lists.
2200 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Redefined the INVITE command. The same command can be used to
2203 invite individuals to the channel but also to manage the invite
2204 list of the channel (to add to and remove from the invite list).
2205 Updated the protocol specs.
2207 * Added new command SILC_COMMAND_BAN that can be used to manage
2208 the ban list of the channel. Updated the protocol specs.
2210 * Removed the channel modes: the SILC_CMODE_BAN and the
2211 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2212 in the CMODE command. The equivalent features are now available
2213 using INVITE and BAN commands. Updated the protocol specs.
2215 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2216 in the network about change in the current ban list. The notify
2217 type is not used by the client.
2219 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2220 support the invite lists.
2222 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Added new function silc_string_regexify that converts string
2225 including wildcard characters into regex string that can
2226 be used by the GNU regex library. Added into the file
2227 lib/silcutil/silcutil.[ch].
2229 Added silc_string_regex_combine to combine to regex strings
2230 into one so that they can be used as one regex string by
2231 the GNU regex library. Added into the file
2232 lib/silcutil/silcutil.[ch].
2234 Added silc_string_regex_match to match two strings. It returns
2235 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2237 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Imported GNU regex to the soruce tree into lib/contrib.
2240 Fixed some compiler warning from the regex.c.
2242 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Fixed MOTD command in the server to work in router environment.
2246 * Fixed the MOTD command in the client library to support
2247 the server argument in the command.
2249 * Added `nickname_len' argument to the silc_idlist_add_client
2250 in the server, as the `nickname' argument may be binary data
2253 * Added silc_idlist_get_channels to return all channels from
2256 * Implemented LIST command to the server. Affected file is
2259 * Implemented the LIST command to the client library and on the
2262 * Added [<user count>] argument to the LIST command reply.
2263 With private channels the user count is not shown.
2265 * Updated TODO and README.
2267 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * The client entry's data.registered must be TRUE even with
2270 global client entry on global client list. The data.registered
2271 is used to check whether the client is anymore in the network,
2272 for example with WHOWAS command so it must be valid.
2274 * Fixed the WHOWAS command in the server. It now actually works
2275 in router environment. Added function into silcd/command_reply.c
2276 silc_server_command_reply_whowas_save.
2278 * Added silc_idlist_purge function to the silcd/idlist.c
2279 to periodically purge the ID Cache.
2281 * Fixed INFO command in the server. It works now in router
2282 environment. Added <server name> argument to the INFO command
2283 reply. Updated the protocol specs.
2285 * Fixed minor bug in silc_idcache_purge to not purge if the
2286 expire value is zero.
2288 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2289 they were buggy because of the WHOWAS information.
2291 * Fixed local command MSG to handle the async resolving of
2292 the remote client properly. It used to fail the first MSG.
2293 Affected file silc/local_command.c.
2295 * Added `data_len' field to SilcIDCache context.
2297 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Update TODO. Todo in commands in the server.
2301 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2304 used by routers as broadcast packet to inform other routers
2305 about the changed user mode.
2307 Implemented the notify handling in the server. Affected file is
2308 silcd/packet_receive.c. Added the function
2309 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2311 * Added new generic Channel Payload and deprecated the New Channel
2312 Payload. The New Channel Payload is now the generic Channel
2315 * Added new argument `mode' to the silc_server_send_new_channel
2316 as it is required in the Channel Payload now.
2318 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2319 and created a new and real SilChannelPayload to represent the
2320 new generic Channel Payload. Implemented the encode/decode
2321 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2323 * Added silc_server_get_client_channel_list to return the list
2324 of channels the client has joined for WHOIS command reply.
2325 Affected file silcd/server.[ch].
2327 * Implemented the channel list sending in the WHOIS command reply
2328 in server and in the client.
2330 Implemented the channel list displaying on the user interface
2331 as well. Affected file silc/client_ops.c.
2333 * Added silc_channel_payload_parse_list to parse list of Channel
2334 Payloads. It returns SilcDList list of SilcChannelPayloads.
2335 Client for example can use this function to parse the list of
2336 channels it receives in the WHOIS command reply. The caller
2337 must free the list by calling silc_channel_payload_list_free.
2338 Affected files lib/silccore/silcchannel.[ch].
2340 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Added one new argument <user mode> to the WHOIS command reply
2343 to return the mode of the user in SILC. Updated the protocol
2346 Implemented it to the server and client.
2348 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * Fixed the mode printing on the user interface on joining.
2351 Affected file silc/client_ops.c.
2353 * Implemented the UMODE command and user modes in general to the
2354 client library and to the user interface.
2356 * Implemented the UMODE command to the server.
2358 * The server now sends UNKNOWN_COMMAND error status if client sends
2359 unknown command. Affected file silcd/command.c.
2361 * All server commands now handle the command identifier the right
2362 way when sending the command reply to the client. The client can
2363 use to identify the command replies with the identifier.
2365 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Added silc_server_get_client_route to resolve the route to
2368 the client indicated by the client ID. Affected file is
2371 * Added silc_server_relay_packet as general function to relay
2372 packet to arbitrary destination. This deprecates functions
2373 like _send_private_message_key, _relay_notify etc. Affected
2374 file is silcd/packet_send.[ch].
2376 Removed silc_server_send_key_agreement,
2377 silc_server_send_private_message_key and
2378 silc_server_packet_relay_notify functions from the file
2379 silcd/packet_send.[ch].
2383 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2384 server. Affected file silcd/packet_receive.[ch].
2386 * Implemented the KILL command to the client. Implemented the
2387 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2388 Affected files lib/silcclient/command[_reply].c and
2389 lib/silcclient/client_notify.c. Implemented the KILL notify
2390 printing in the user inteface.
2392 * Fixed a lot silc_parse_nick memory leaks from the client
2393 library in the file lib/silcclient/command.c.
2395 * Changed the silc_server_send_notify_on_channels's `sender'
2396 argument from SilcSocketConnection to SilcClientEntry to
2397 check the sender as entry and not as connection object and not
2398 to send to the client provided as argument. The affected file
2399 is silcd/packet_send.[ch].
2401 * The notify packets that are destined directly to the client used
2402 to not to be processed by the server. Now changed that and the
2403 server processes all notify packets. After relaying the packet
2404 to the client the notify packet is processed in the server.
2406 * The silc_server_free_client_data now checks whether there is
2407 pending outgoing traffic for the client and purges the data to
2408 the network before removing the client entry.
2410 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2412 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2413 an client is killed from the SILC Network. Updated the protocol
2416 Added new function silc_server_send_notify_killed to the
2417 silcd/packet_send.[ch].
2419 * Added function silc_server_packet_relay_notify to relay notify
2420 packets that are destined directly to a client. In this case
2421 the server does not process the notify packets but merely relays
2422 it to the client. Affected file silcd/packet_send.[ch].
2424 Added also silc_server_packet_process_relay_notify to check
2425 whereto relay the notify. Affected file is
2426 silcd/packet_receive.[ch].
2428 * Implemented the KILL command to the server.
2432 * Added the backup schema desgined last fall to the protocol
2433 specs for everyone to see. The specification is in the
2434 *-spec-xx.txt draft and the packet type definitions for the
2435 backup routers is in *-pp-xx.txt draft. Thusly, added also
2436 new packet type SILC_PACKET_CELL_ROUTERS.
2438 * A big security problem in the implementation discovered. The
2439 signoff of an client did not cause new channel key generation
2440 which it of course should've done. The channel keys must be
2441 always re-generated when client leaves (or signoffs) the channel.
2442 The silc_server_remove_from_channels funtion now handles
2443 the channel key re-generation.
2445 * Added `sender' argument to the silc_server_send_notify_on_channels
2446 to not to send the client provided as argument. Affected file
2447 silcd/packet_send.[ch].
2449 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Implemented OPER and SILCOPER commands into the server and
2454 * Added silc_auth_verify and silc_auth_verify_data to verify
2455 the authentication directly from the authentication payload.
2456 It supports verifying both passphrase and public key based
2457 authentication. Affected file lib/silccore/silcauth.[ch].
2459 * Added `hash' field to the SilcIDListData structure. It is the
2460 hash negotiated in the SKE protocol. Affected file is
2463 * Slight redesigning of the SilcAuthPayload handling routines.
2464 Do not send SilcPKCS but SilcPublicKey as argument.
2466 * Implemented the public key authentication support to the
2467 serverconfig. The public key is loaded from the provided path
2468 and saved as authentication data to void * pointer. Thus,
2469 changed the unsigned char *auth_data to void *auth_data;
2471 * Fixed SHUTDOWN command to send the reply before the server
2472 is shutdown. :) Affected file silcd/command.c.
2474 * Fixed fatal bug in CONNECT command. The hostname was invalid
2475 memory and server crashed. Affected file silcd/command.c.
2477 * Fixed fatal bug in CLOSE command. The server_entry became
2478 invalid but was referenced later in the command. Affected file
2481 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Fixed fatal bug in failure packet handling. Server ignored
2484 the failure and thus crashed when it came.
2488 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2491 that the command may be executed only once in (about) 2 seconds.
2492 The old SILC_CF_LAG flag is same but allows command bursts up
2493 to five before limiting.
2495 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2496 server code. Various commands now includes the CF_LAG_STRICT
2497 flag to disallow any kind of miss-use of the command.
2499 * Fixed the silc_buffer_unformat to not to allocate any data
2500 if the length of the data is zero. It used to allocate the
2501 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2503 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Changed the format of AdminConnection configuration section
2506 in the server. Added username of the admin to the format.
2507 Affected files silcd/serverconfig.[ch].
2509 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2510 to return admin configuration data by host, username and/or
2513 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Implemented WHOWAS command to the server. Added the functions:
2517 silc_server_command_whowas_parse,
2518 silc_server_command_whowas_send_reply,
2519 silc_server_command_whowas_from_client and
2520 silc_server_command_whowas_from_server
2522 * Added <Client ID> argument to the WHOWAS command reply. Updated
2523 the protocol specs accordingly.
2525 * Implemented WHOWAS command and command_reply to the client
2528 Implemented the WHOWAS printing on the user interface.
2530 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Added new argument to the WHOWAS command reply, the real name.
2533 It is an optional argument. Updated the protocol specs.
2535 * Added SilcIDCacheDestructor callback that is registered when
2536 the SilcIDCache is allocated. The callback is called when
2537 an cache entry in the ID Cache expires, or is purged from the
2538 cache. Added into lib/silccore/idcache.[ch].
2540 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2541 to destruct the client entries when the cache entry expires.
2542 Other ID Cache's in server and in the client library ignores
2545 * If the ID Cache entry's `expire' field is zero then the entry
2546 never expires. Added boolean `expire' argument to the
2547 silc_idcache_add function in the lib/silccore/idcache.[ch].
2548 If it is TRUE the default expiry value is used.
2550 * Added silc_server_free_client_data_timeout that is registered
2551 when client disconnects. By default for 5 minutes we preserve
2552 the client entry for history - for WHOWAS command.
2554 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Added support to the server to enforce that commands are not
2557 executed more than once in 2 seconds. If server receives
2558 commands from client more frequently, timeout is registered
2559 to process the commands. Affected file silcd/command.c.
2560 Added new function silc_server_command_process_timeout.
2562 * Changed NICK_NOTIFY handling in client library to check that
2563 if the client's nickname was changed, so there is no need to
2564 resolve anything from the server.
2566 * Removed error printing from the WHOIS and IDENTIFY commands.
2567 If error occurs then it is ignored silently in the client library.
2568 The application, however, may map the received error to
2569 human readable error string. The application currently maps
2570 the NO_SUCH_NICKNAME error to string.
2572 * Made the command status message public to the application. Moved
2573 them from lib/silcclient/command_reply.c to
2574 lib/silcclient/command_reply.h. The application can map the
2575 received command status to the string with the
2576 silc_client_command_status_message function.
2578 * Added check to the server to check that client's ID is same
2579 as the Source ID in the packet the client sent. They must
2582 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Added dist-bzip hook to the Makefile.am to make bzip2
2585 compressed distributions.
2587 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Server now enforces the maximum length for the nickname and
2590 the channel as protocol specification dictates. 128 bytes for
2591 nickname and 256 bytes for channel name.
2593 * Moved the WHOIS printing to the application. The client libary
2594 does not print out the WHOIS information anymore, the application
2595 must do it. Renamed silc_client_command_reply_whois_print to
2596 the silc_client_command_reply_whois_save.
2598 The client's idle time is also sent to the application now, and
2599 the idle is shown on screen.
2601 * Added silc_client_command_reply_identify_save to save the
2602 received IDENTIFY entries.
2604 * Do not check for channel private keys in message sending and
2605 reception if the channel does not have the PRIVKEY mode set.
2606 Affected file lib/silclient/client_channel.c.
2608 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2611 just surfaced after chaning the JOIN procedure.
2613 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Added silc_client_get_clients_by_list to get client entries
2616 from Client ID list, that is returned for example by JOIN
2617 and USERS command replies. The application should use this
2618 function for example when JOIN command reply is received to
2619 resolve the clients already on the channel (library does not
2620 do that anymore as USERS command reply is not used in the JOIN
2621 procedure anymore). Affected files lib/silcclient/silcapi.h and
2622 lib/silcclient/idlist.c.
2624 * JOIN command reply and USERS command reply returns now SilcBuffer
2625 pointers instead of unsigned char pointers when returning
2626 the client list and mode list.
2628 * Added <Client ID> argument to the JOIN command reply, mainly
2629 for the server to identify for which client the command was
2630 originally sent. Updated protocol specs accordingly.
2632 * Added SilcDlist private_key pointer to the SilcChannelEntry
2633 in the client to support the channel private keys. Affected
2634 file is lib/silcclient/idlist.h.
2636 * Added SilcChannelPrivateKey argument to the function
2637 silc_client_send_channel_message so that application can choose
2638 to use specific private ke if it wants to. If it is not provided,
2639 the normal channel key is used, unless private keys are set.
2640 In this case the first (key that was added first) is used
2641 as the encryption key.
2643 * Implemented the support for channel private key handling.
2644 Implemented the following functions:
2646 silc_client_add_channel_private_key,
2647 silc_client_del_channel_private_keys,
2648 silc_client_del_channel_private_key,
2649 silc_client_list_channel_private_keys and
2650 silc_client_free_channel_private_keys
2652 Affected file lib/silcclient/client_channel.c.
2654 * Added the support for the private keys in the channel message
2655 sending and encryption and in the message reception and
2656 decryption. Affected funtions are
2657 silc_client_send_channel_message and silc_client_channel_message.
2659 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Added SKE's key verify callback to the client library's
2662 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2664 * Removed the statement that server (or router) must send USERS
2665 command reply when joining to the channel so that the client
2666 knows who are on the channel. Instead, the client list and
2667 client's mode list is now sent in the JOIN command reply to the
2668 client who joined channel. This is better solution.
2670 * Added function silc_server_get_users_on_channel and function
2671 silc_server_save_users_on_channel to the silcd/server.[ch].
2673 * Removed function silc_server_command_send_users from the
2676 * Do not show topic on the client library anymore. The topic is
2677 sent in the command reply notify to the application and the
2678 application must show the topic now.
2680 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Added client searching by nickname hash into the IDENTIFY and
2683 WHOIS commands in the server as they were clearly missing from
2684 them. Affected file is silcd/command.c.
2686 * Fixed a bug in private message receiving in the client library.
2687 The remote ID was freed and it wasn't supposed, now it is
2690 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Minor fix to the channel payload; allocate the data area, as it
2693 needs to be of specific length.
2695 * If the key agreement port is zero then the operating
2696 system will define the bound port. Affected files are
2697 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2699 * Added new function silc_channel_payload_decrypt into the file
2700 lib/silccore/silcchannel.[ch].
2702 * Moved the channel message etc, check from silc_packet_decrypt
2703 to applications. The library calls now a generic
2704 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2705 when the packet is either normal or special. This was done to
2706 allow more wide range of checking that was not allowed when
2707 the code was in library. Now applications can do virtually any
2708 checks to the packet and return to the library the decision how
2709 the packet should be processed. Affected files are
2710 lib/silccore/silcpacket.[ch].
2712 Added silc_server_packet_decrypt_check to the server and
2713 silc_client_packet_decrypt_check to the client library.
2715 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2716 to send with specified source and destination information.
2718 * Channel message delivery between routers was broken after the
2719 channel key distribution was fixed earlier. The channel key
2720 was used be to distributed to other routers as well which is not
2721 allowed by the protocol. Now this is fixed and channel keys
2722 really are cell specific and the channel message delivery between
2723 routers comply with the protocol specification.
2725 * Fixed various commands in server to check also the global list
2726 for the channel entry and not just the local list. The affected
2727 file silcd/command.c.
2729 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Added assert()s to buffer formatting and unformatting routines
2732 to assert (if --enable-debug) when error occurs. Affected
2733 file: lib/silcutil/silcbuffmt.c.
2735 * Changed to auto-reconnect to check whether the remote host is
2736 router and register the re-connect timeout if it is. It used
2737 to check that whether we are normal server, but router must do
2738 auto-reconnect with another router as well. Affected file
2741 * Removed the [<key len>] option from CMODE command as the cipher
2742 name decides the key length, nowadays. See the defined ciphers
2743 from the protocol specification.
2745 * Added [<hmac>] option to the CMODE command to define the HMAC
2746 for the channel. Added SILC_CMODE_HMAC channel mode.
2748 * Added [<hmac>] option for the JOIN command so that user can
2749 select which HMAC is used to compute the MACs of the channel
2752 * Added Hmac field to the Channel Message Payload. The integrity
2753 of plaintext channel messages are now protected by computing
2754 MAC of the message and attaching the MAC to the payload. The
2755 MAC is encrypted. Now, it is clear that this causes some
2756 overhead to the size of the packet but rationale for this is that
2757 now the receiver can verify whether the channel message decrypted
2758 correctly and also when private keys are set for the channel the
2759 receiver can decrypt the packet with several keys and check from
2760 the MAC which key decrypted the message correctly.
2762 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2763 lib/silccrypt/silccipher.[ch].
2765 * Added silc_hash_len to return the digest length into the
2766 lib/silcrypt/silchash.[ch].
2768 * Rewrote parts of Silc Channel Payload interface in the
2769 lib/silccore/silcchannel.[ch]. The encode function now also
2770 encrypts the packet and parse function decrypts it.
2772 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Fixed a minor formatting bug in the SKE's key material processing.
2775 It actually might have processed the keys wrong way resulting
2778 * Redefined the mandatory HMAC algorithms and added new algorithms.
2779 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2780 and hmac-md5 truncated to 96 bits. The mandatory is now
2781 hmac-sha1-96. Rest are optional (including the one that used
2782 to be mandatory). Rationale for this is that the truncated HMAC
2783 length is sufficient from security point of view and can actually
2784 make the attack against the HMAC harder. Also, the truncated
2785 HMAC causes less overhead to the packets. See the RFC2104 for
2788 * Added new [hmac] configuration section. The SKE used to use
2789 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2790 is of course wrong. The official names that must be proposed in
2791 the SKE are the ones defined in the protocol specification
2792 (hmac-sha1-96 for example). The user can configure any hmac
2793 using any hash function configured in the [hash] section. At
2794 least, the mandatory must be configured.
2796 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2798 * Added HMAC list to the SKE proposal list. It has now both
2799 hash algorithm list and HMAC list. This makes the protocol
2800 incompatible with previous versions. The SKE now seems to work
2801 the way it is supposed to work, for the first time actually.
2803 * Defined plain Hash algorithms to the protocol specification.
2806 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Implemented support for key agreement packets into the server.
2809 Added functions silc_server_key_agreement and
2810 silc_server_send_key_agreement. Other than these functions,
2811 server has nothing to do with this packet.
2813 * Added support for private message key packets into the server.
2814 Added functions silc_server_private_message_key and
2815 silc_server_send_private_message_key.
2819 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2820 called in the protocol's final callback instead in the END
2821 protocol state. This makes a little more sense and in the same
2822 time in client we can use the same protocol routines for normal
2823 key exchange and to key agreement packet handling as well.
2825 * Added to both client's and server's KE protocol context the
2826 SilcSKEKeyMaterial pointer to save the key material. We will
2827 bring the key material to the protocol's final callback by doing
2828 this. The final callback must free the key material.
2830 * Added SKE's packet_send callback into client's KE protocol
2831 context so that the caller can choose what packet sending function
2832 is used. This way we can use different packet sending when
2833 doing normal SKE when doing key agreement packet handling (in
2834 the key agreement packet handling we do not want to encrypt
2837 * Implemented the responder side of the key agreement routines
2838 in the client. The client can now bind to specified port and
2839 accept incoming key negotiation. The key material is passed
2840 to the application after the protocol is over.
2842 * Implemented the processing of incoming Key Agreement packet
2843 in the client. Added function silc_client_key_agreement to
2846 * Implemented the intiator side of the key agreement routines
2847 in the client. The client can now initiate key agreement with
2848 another remote client. The key material is passed to the
2849 application after the protocol is over.
2851 * Created client_keyagr.c to include all the key agreement
2854 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2855 SILC_TASK_CALLBACK except that it is not static.
2857 * Created client_notify.c and moved the Notify packet handling
2858 from the client.[ch] into that file.
2860 * Created client_prvmsg.c and moved all private message and
2861 private message key routines from the client.[ch] into that file.
2863 * Create client_channel.c and moved all channel message and
2864 channel private key routines from the client.[ch] into that file.
2866 * Changed silc_client_get_client_by_id_resolve to resolve with
2867 WHOIS command instead of IDENTIFY command, in the file
2868 lib/silclient/idlist.c.
2870 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Implemented the SKE's responder side to the Client library.
2874 * When FAILURE is received to the protocol do not trust it
2875 blindly. Register a timeout to wait whether the remote closes
2876 the connection as it should do it, only after that process the
2877 actual failure. This was changed to both client and server.
2879 * Added client_internal.h to include some of the structures
2880 there instead of client.h in lib/silcclient/.
2882 * Added function silc_task_unregister_by_callback to unregister
2883 timeouts by the callback function.
2885 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Some "Incomplete WHOIS info" errors has been appearing on the
2888 log files. Took away the entry->userinfo check from WHOIS
2889 reply sending. The entry->userinfo is now " " if client did not
2890 provide one. I thought this was fixed earlier but something
2891 is wrong still. Let's see if the error still appears.
2893 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Fixed a minor bug in the login when the channel key is
2896 re-generated in the server. It used to generate the key in
2897 wrong order and thus caused problems in the channel traffic.
2899 * Fixed a minor bug in channel key distsribution after
2900 KICK command. The key was not sent to the router even though
2903 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Added silc_ske_process_key_material_data as generic routine
2906 to process any key material as the SILC protocol dictates. The
2907 function is used by the actual SKE library but can be used by
2908 applications as well. This relates to the private message keys
2909 and the channel private keys since they must be processed the
2910 same way the normal SILC session keys. The protocol dictates
2911 this. Affected files: lib/silcske/silcske.[ch].
2913 Added also silc_ske_free_key_material to free the
2914 SilcSKEKeyMaterial structure.
2916 * Defined silc_cipher_set_key function to set the key for
2917 cipher without using the object's method function. The affected
2918 files: lib/silccrypt/silccipher.[ch].
2920 * Implemented silc silc_client_add_private_message_key,
2921 silc_client_add_private_message_key_ske,
2922 silc_client_del_private_message_key,
2923 silc_client_list_private_message_keys and
2924 silc_client_free_private_message_keys functions in the
2927 Added functions silc_client_send_private_message_key to send
2928 the Private Message Key payload and silc_client_private_message_key
2929 to handle incoming Private Message Key payload.
2931 * Added Cipher field to the Private Message Key payload to set
2932 the cipher to be used. If ignored, the default cipher defined
2933 in the SILC protocol (aes-256-cbc) is used.
2935 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Removed lib/silcclient/ops.h file.
2939 Redefined parts of the SILC Client Library API. Created new
2940 file silcapi.h that deprecates the ops.h file and defines the
2941 published Client Library API. Defined also private message key
2942 API and channel private key API into the file.
2944 This is the file that the application must include from the
2945 SILC Client Library. Other files need not be included by
2946 the application anymore.
2948 * Added new key_agreement client operation callback and also
2949 defined the Key Agreement library API for the application.
2951 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2954 is used by clients to request key negotiation between another
2955 client in the SILC network. If the negotiation is started it
2956 is performed using the SKE protocol. The result of the
2957 negotiation, the secret key material, can be used for example
2958 as private message key.
2960 Implemented the Key Agreement payload into the files
2961 lib/silccore/silauth.[ch].
2963 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Redefined ciphers for the SILC protocol. Added some new ciphers
2966 and defined the key lengths for the algorithms. Changed the
2967 code accordingly. The default key length is now 256 bits.
2969 * Fixed SKE key distribution function silc_ske_process_key_material
2970 when the key length is more than 128 bits. The default key
2971 length in SILC is now 256 bits.
2973 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2974 to indicate unsupported algorithm.
2976 * Renamed rijndael.c to aes.c and all functions as well.
2978 * Fixed a long standing channel key setting bug in client library.
2979 Weird that it has never surfaced before.
2981 * Fixed bug in channel deletion. If the entire channel is removed
2982 then it must also delete the references of the channel entry
2983 from the client's channel list as the client's channel entry and
2984 the channel's client entry share same memory.
2986 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Implemented CONNECT and SHUTDOWN commands in the client.
2990 * Implemented CLOSE command to the client.
2992 * Added the function silc_idlist_find_server_by_name into the
2993 files silcd/idlist.[ch].
2995 Added the function silc_idlist_find_server_by_conn into the
2996 files silcd/idlist.[ch].
2998 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * DIE command was renamed to SHUTDOWN. Updated the both code
3003 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3004 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3006 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3009 * Added function silc_server_create_connection function to create
3010 connection to remote router. My server implementation actually
3011 does not allow router to connect to normal server (it expects
3012 that normal server always initiates the connection to the router)
3013 so the CONNECT command is only good for connecting to another
3016 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3019 or some other client was kicked from the channel.
3021 Implemented the handling of the notify type to both client
3024 Implemented silc_server_send_notify_kicked to send the KICKED
3025 notify. It is used to send it to the server's primary router.
3027 * Implemented the KICK command into server and client.
3029 * Added `query' argument to the silc_idlist_get_client function
3030 to indicate whether to query the client from server or not if
3033 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3034 to indicate that the client is not channel founder.
3038 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Removed the rng context from SilcPacketContext structure and
3041 changed that the packet routine uses the Global RNG API.
3043 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Added support for quit message that client can "leave" on the
3046 channel when it quits the SILC. It is ditributed inside the
3047 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3049 Added silc_server_free_client_data that will take the
3050 signoff message as argument.
3052 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3054 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Updated parts of the protocol specification to keep it up
3059 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3062 payloads in one packet.
3064 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3065 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3066 use now the new List flag.
3068 * Also deprecated the following packet types: REPLACE_ID,
3069 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3071 * Added list support for Notify packet in server.
3073 * Added silc_server_send_notify_channel_change to send the
3074 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3075 the silc_server_send_replace_id.
3077 * Added silc_server_send_notify_nick_change to send the
3078 NICK_CHANGE notify type. Deprecates the function
3079 silc_server_send_replace_id.
3081 * Added silc_server_send_notify_join to send the JOIN notify type.
3082 Deprecates the function silc_server_send_new_channel_user.
3084 * Added silc_server_send_notify_leave to send LEAVE notify type.
3085 Deprecates the function silc_server_send_remove_channel_user.
3087 * Added silc_server_send_notify_cmode and
3088 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3089 types. Deprecates the silc_server_send_set_mode function.
3091 * Added SERVER_SIGNOFF notify type to indicate that server has
3092 quit. This means that all clients on the channel from that
3093 server will drop. This can be also used when netsplit happens.
3095 Deprecated REMOVE_ID packet type since it is not needed anymore
3098 Added silc_server_send_notify_server_signoff to send the
3099 SERVER_SIGNOFF notify type. Deprecates the function
3100 silc_server_send_remove_id.
3102 Added also silc_server_send_notify_signoff to send the
3103 SIGNOFF notify type.
3105 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3106 SILC protocol from this day on. Changed the protocol
3107 specification as well.
3109 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3110 notify type. It is used between routers to notify about
3111 topic changes on a channel.
3113 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3116 * Partly updated the protocol specification to comply with the
3117 changes now made. It is still though a bit outdated.
3119 * The JOIN notify type now takes one extra argument <Channel ID>.
3120 The packet used to be destined to the channel but now the
3121 JOIN type may be sent as list thus it is impossible to
3122 destine it to any specific channel. By adding this argument
3123 it is again possible.
3125 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Added CREDITS file. The CHANGES and CREDITS file will appear
3128 in the distribution as well.
3130 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3133 types in the server's silcd/packet_receive.c.
3135 * Implemented CMODE and CUMODE to work in router environment.
3137 * Fixed minor encoding and decoding buglet from the
3138 lib/silccore/silcmode.c.
3140 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3143 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3145 * Changed all SilcConfigServer* and silc_config_server* to
3146 SilcServerConfig* and silc_server_config*, respectively.
3149 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Associated the ID (client or server ID) to the Authentication
3152 Payload to avoid any possibility of forging. Updated the
3153 protocol specification and the code accordingly.
3155 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * The RSA key length is now save to the RsaKey context in the
3158 key generation process in lib/silccrypt/rsa.c. The key length
3159 is now used to figure out the maximum size of the block allowed
3160 to be encrypted/signed.
3162 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3163 is equivalent to the silc_mp_mp2bin but does not allocate any
3166 * Changed silc_mp_mp2bin API to take length argument. If it is
3167 non-zero then the buffer is allocated that large. If zero, then
3168 the size is approximated using silc_mp_sizeinbase, which however
3171 * Created Global RNG API which is global RNG that application can
3172 initialize. After initializing, any routine anywhere in the
3173 code (including library) can use RNG without allocating a new
3174 RNG object. This was done to allow this sort of use of the
3175 RNG in code that has no chance to allocate RNG object. All
3176 applications currently allocate this and many routines in the
3177 library use this. Affected file lib/silccrypt/silcrng.[ch].
3179 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3180 it to use the Global RNG API.
3182 * Defined Authentication Payload into protocol specification that
3183 is used during SILC session to authenticate entities. It is
3184 used for example by client to authenticate itself to the server
3185 to obtain server operator privileges.
3187 Implemented this payload into the lib/silccore/silcauth.[ch].
3188 Implemented also routines for public key based authentication
3189 as the new protocol specification dictates.
3191 Moved definitions of different authentication methods from
3192 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3194 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3195 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3196 silc_pkcs_verify_with_hash functions into the file
3197 lib/silccrypt/silcpkcs.[ch].
3199 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * The client entry's userinfo pointer must be always valid.
3202 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3203 will fail since it requires the userinfo. Now, the userinfo
3204 is allocated as "" if actual userinfo does not exist. Actually,
3205 it must exist and it is totally Ok to drop client connections
3206 that does not announce the userinfo. However, we will make
3207 this workaround for now.
3209 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3210 to return the remote port by socket.
3212 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3215 SILC_SERVER_PENDING_EXEC and added an new macro
3216 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3217 data or when error occurs while processing the pending command.
3219 Added new argument `destructor' into silc_server_command_pending
3220 and to the SilcServerCommandPending object. This destructor is
3221 now called after calling the pending callback or if error occurs
3222 immediately. If error occurs the actual pending callback won't
3223 be called at all - only the destructor. The destructor may be
3224 NULL if destructor is not needed.
3226 All this applies for client library code as well. Similar
3227 changes were made there as well for the pending commands.
3229 In the client, the application must now allocate the
3230 SilcClientCommandContext with the silc_client_command_alloc
3233 * Added reference counter to the SilcServerCommandContext. Added
3234 function silc_server_command_alloc and silc_server_command_dup
3237 Same type of functions added to the client library for the same
3240 * Removed the cmd_ident from IDListData away since it is now
3241 global for all connections. It is the command identifier used
3242 in command sending and with pending commands. The affected file
3245 * Added reference counter to the SilcSocketConnection objecet to
3246 indicate the usage count of the object. The object won't be
3247 freed untill the reference counter hits zero. Currently only
3248 server uses this, and client ignores it. The client must be
3249 set to use this too later. The affected files are
3250 lib/silccore/silcsockconn.[ch]. Added also the function
3251 silc_socket_dup to increase the reference counter.
3253 This was mainly added because it is possible that the socket
3254 is removed underneath of pending command or other async
3255 operation. Now it won't be free'd and proper DISCONNECTING
3256 flags, etc. can be set to avoid sending data to connection that
3257 is not valid anymore.
3259 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3260 the connection. After that it sets SILC_SET_DISCONNECTED.
3261 It is, however, possible that the socket data is not still freed.
3262 The silc_server_packet_process now checks that data is not
3263 read or written to connection that is DISCONNECTED. The socket
3264 get's freed when the reference counter hits zero.
3266 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3268 * Changed the client operation API: channel_message operation's
3269 `sender' is now the client entry of the sender, not the nickname
3270 and the `channel' is the channel entry, not the channel name.
3272 In the private_message operation the `sender' is now also the
3273 client entry of the sender not the nickname.
3275 Affected file is lib/silcclient/ops.h and all applications
3276 using the client operations.
3278 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Moved the calling of ops->connect() from connect_to_server_final
3281 into receive_new_id functin since that is the point when the
3282 client is actually allowed to send traffic to network. The
3283 affected file is lib/silcclient/client.c.
3285 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3288 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3289 (if needs broadcasting) instead of broadcasting the packets one
3290 by one which would make a burst in the network traffic.
3292 * Added `broadcast' argument to the functions in silcd/server.[ch]
3293 silc_server_create_new_channel[_with_id] to indicate whether
3294 to send New Channel packet to primary router.
3296 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Added new function into the silcd/server.[ch] files:
3299 silc_server_create_new_channel_with_id to create new channel with
3300 already existing Channel ID.
3302 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3303 lib/silccore/silcpacket.h. This packet is used t send list of
3304 Set Mode payloads inside one packet. Server uses this to set
3305 the modes for the channels and clients on those channels, that it
3306 announced to the router when it connected to it. The protocol
3307 specification has been updated accordingly.
3309 * The silc_server_new_channel did not handle the packet coming
3310 from normal server as it normally does not send that. However,
3311 when it announces its channels it does send it. Implemented
3312 the support for that.
3314 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3315 into the file lib/silccore/id.h.
3317 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Fixed memory leaks in the functions silc_idlist_del_client,
3320 silc_idlist_del_channel and silc_idlist_del_server in the file
3321 silcd/idlist.c. All of those leaked like a sieve.
3323 * Fixed some small memory leaks in the client's function
3324 silc_client_notify_by_server.
3326 * Added functions into silcd/server.c: silc_server_announce_clients,
3327 silc_server_announce_channels and silc_server_announce_server.
3328 These functions are used by normal and router server to announce
3329 to its primary router about clients, channels and servers (when
3330 router) that we own. This is done after we've connected to the
3333 These functions effectively implements the following packet types:
3334 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3335 and SILC_PACKET_NEW_ID_LIST.
3337 * Added new functions into the silcd/packet_receive.[ch]:
3338 silc_server_new_id_list, silc_server_new_channel_list and
3339 silc_server_new_channel_user_list to handle the incoming
3340 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3342 * Added support of changing Channel ID in the function
3343 silc_server_replace_id. If the server that announces a channel
3344 to the router already exists in the router (with same name but
3345 with different Channel ID), router is responsible to send
3346 Replace ID packet to the server and force the server to change
3347 the Channel ID to the one router has.
3349 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3350 client that the Channel ID has been changed by the router. The
3351 normal server sends this to the client. Client must start using
3352 the new Channel ID as the channel's ID.
3354 Implemented handling of this new type into lib/silcclient/client.c
3355 into the function silc_client_notify_by_server.
3357 * Added new function silc_idlist_replace_channel_id into the files
3358 silcd/idlist.[ch] to replace the Channel ID.
3360 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Call silc_server_command_identify_check always when processing
3363 the IDENTIFY command in silcd/command.c
3365 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3368 send keepalive packets. The packet can be sent by clients,
3369 servers and routers.
3371 Added function silc_socket_set_heartbeat into the file
3372 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3373 If not set, the heartbeat is not performed. The actual
3374 heartbeat is implemented in the low level socket connection
3375 library. However, application is responsible of actually
3378 Added silc_server_send_heartbeat to send the actual heartbeat
3379 packet into silcd/packet_send.[ch]. Server now performs
3380 keepalive with all connections.
3382 * Added silc_task_get_first function into lib/silcutil/silctask.c
3383 to return the timeout task with shortest timeout. There was a bug
3384 in task unregistration that caused problems. TODO has been
3385 updated to include that task system must be rewritten.
3387 * The client library will now resolve the client information when
3388 receiving JOIN notify from server for client that we know but
3389 have incomplete information.
3391 * Rewrote parts of silc_server_remove_from_channels and
3392 silc_server_remove_from_one_channel as they did not remove the
3393 channel in some circumstances even though they should've.
3395 * Encryption problem encountered in server:
3397 The LEAVE command used to send the Channel Key packet to the
3398 router immediately after generating it. However, the code
3399 had earlier sent Remove Channel user packet but not immediately,
3400 ie. it was put to queue. The order of packets in the router
3401 was that Channel Key packet was first and Remove Channel User
3402 packet was second, even though they were encrypted in the
3403 reverse order. For this reason, MAC check failed. Now, this
3404 is fixed by not sending the Channel Key packet immediately but
3405 putting it to queue. However, this is more fundamental problem:
3406 packets that are in queue should actually not be encrypted
3407 because packets that are sent immediately gets encrypted
3408 actually with wrong IV (and thus MAC check fails). So, packets
3409 that are in queue should be encrypted when they are sent to
3410 the wire and not when they put to the queue.
3412 However, the problem is that the current system has not been
3413 designed to work that way. Instead, the packet is encrypted
3414 as soon as possible and left to the queue. The queue is then
3415 just purged into wire. There won't be any fixes for this
3416 any time soon. So, the current semantic for packet sending
3419 o If you send packet to remote host and do not force the send
3420 (the packet will be in queue) then all subsequent packets to the
3421 same remote host must also be put to the queue. Only after the
3422 queue has been purged is it safe again to force the packet
3425 o If you send all packets immediately then it safe to send
3426 any of subsequent packets through the queue, however, after
3427 the first packet is put to queue then any subsequent packets
3428 must also be put to the queue.
3430 Follow these rules and everything works fine.
3432 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Added new function silc_server_remove_clients_by_server to
3435 remove all client entries from ID list when the server connection
3436 is lost. In this case it is also important to invalidate all
3437 client entires as they hold the invalid server entry. This
3438 fixes fatal bug when server has lost connection and will reconnect
3441 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Made some sanity checks to silc_server_daemonise like to check
3444 whether the requested user and group actually exists.
3446 * Added sanity check to SKE's silc_ske_responder_finish to check
3447 that the public and private key actually is valid.
3449 * Invalidate the client's nickname when receiving Replace ID
3450 packet and the Client ID is being replaced. This means that the
3451 server will query the nickname if someone needs it (client)
3454 * Sort the ID Cache in client library when the ID Cache data
3455 has changed (needs sorting).
3457 * Do not allow for SILC client to create several connections to
3458 several servers. The client does not support windows right now
3459 and generating multiple connections causes weird behaviour.
3461 Irssi-silc client does support windows and can handle several
3462 connections without problems, see: www.irssi.org and SILC plugin.
3464 * Fixed some places where client was added to the IDList. The
3465 rule of thumb is following (in order to get everything right):
3466 If the client is directly connected local client then the
3467 `connection' argument must be set and `router' argument must be
3468 NULL to silc_idlist_add_client function. If the client is not
3469 directly connected client then the `router' argument must
3470 bet set and the `connection' argument must be NULL to the
3471 silc_idlist_add_client function.
3473 * The funtion silc_server_packet_send_local_channel actually did
3474 not check whether the client was locally connected or not. It
3475 does that now. Fixed a bug related to LEAVE command.
3477 * Fixed Remove Channel User payload parsing bug in server's
3478 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3480 * The server's silc_server_save_channel_key now checks also the
3481 global ID list for the channel as it might not be in the local
3482 list. Fixed a bug related to LEAVE command.
3484 * Is this the end of the [<unknown>] buglet that has been lurking
3485 around for a long time? A little for loop fix in server's
3486 silc_server_command_whois_parse that is used by both IDENTIFY
3487 and WHOIS command. At least, this was a clear bug and a cause
3488 of one type of [<unknown>] buglet.
3490 * WHOIS and IDENTIFY commands call the function
3491 silc_server_command_[whois/identify]_check function even if
3492 we are not router server.
3494 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Added --with-gmp configuration option. If set the GMP
3497 is always compiled in the SILC source tree. If not set then
3498 it is checked whether the system has the GMP3 installed. If
3499 it has then the GMP won't be compiled (the system's headers
3500 and library is used), if it doesn't have it then the GMP is
3501 compiled in the SILC source tree.
3503 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Changed RSA private exponent generation to what PKCS #1
3506 suggests. We try to find the smallest possible d by doing
3507 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3508 not security fix but optimization.
3510 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Added new config entry [Identity] to fork the server and run
3513 it as specific user and group. A patch from Bostik.
3515 * Imported Dotconf configuration library into lib/dotconf.
3516 This will be used to create the SILC configuration files later.
3517 It will appear in the distsribution after this commit.
3519 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * A big code auditing weekend happening. Auditing code for
3522 obvious mistakes, bugs and errors. Also, removing any code
3525 Removed files for being obsolete:
3527 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3528 inline in the file lib/silcutil/silcbuffer.h)
3530 o lib/silcutil/silcbufutil.c (the header has inline versions)
3532 Changed code to fix possible error conditions:
3534 o The buffer formatting routines now check that the destination
3535 buffer really has enough space to add the data. This applies for
3536 both buffer formatting and unformatting
3537 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3538 unformatting was changed to accomodate following rules:
3539 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3540 sent to the function while XXX_*STRING will not allocate or copy
3541 the data into the buffer. Instead it sets the pointer from the
3542 buffer into the pointer sent as argument (XXX_*STRING used to
3543 require that the pointer must be allocated already). This change
3544 makes this whole thing a bit more consistent and more optimized
3545 (note that the data returned in the unformatting with XXX_*STRING
3546 must not be freed now). The routines return now -1 on error.
3548 o Tried to find all code that use buffer_format and buffer_unformat
3549 and added return value checking to prevent formatting and
3550 especially unformatting errors and possible subsequent fatal
3553 o Changed ske->x and ske->KEY to mallocated pointers in
3554 lib/silcske/silcske.h. Fixed possible data and memory leak.
3556 o Added return value checking to all *_parse* functions. Fixed
3557 many memory leaks as well.
3559 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3560 so that buffer overflows would not happen. All code now also
3561 checks the return value as it can fail.
3563 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Added reconnection support to server if the normal server looses
3566 its connection to the router (for example if router is rebooted).
3567 The server performs normal reconnection strategy implemented
3568 to the server. Affected file silcd/server.c.
3570 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Added new packet type SILC_PACKET_SET_MODE that is used to
3573 distribute the information about changed modes (for clients,
3574 channels and clients channel modes) to all routers in the
3575 network. Updated the protocol specification accordingly.
3577 Added functions into silcd/packet_send.c and
3578 silcd/packet_receive.c: silc_server_send_set_mode,
3579 silc_server_set_mode.
3581 Added new files silcmode.[ch] into lib/silccore that implements
3582 the encoding and decoding of Set Mode Payload. Added new type
3583 SilcSetModePayload. Moved the definitions of different modes
3584 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3586 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Oops, a little mistake in server's connection authentication
3589 protocol. The protocol is not ended with FAILURE but with
3590 SUCCESS if the authentication is Ok. :) Affected file is
3593 * Implemented NICK_CHANGE notify handling in server in the file
3594 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3595 the local clients on the channel. After the changing nickname
3596 in router environment snhould work and the [<unknown>] nickname
3597 should appear no more.
3599 The silc_server_replace_id function that receives the Replace ID
3600 payload now sends the NICK_CHANGE notify type also in the file
3601 silcd/packet_receive.c
3603 * Changed WHOIS and IDENTIFY command to support the maximum amount
3604 of arguments defined in protocol specs (3328 arguments). This
3605 fixed a bug that caused problems when there were more than three
3608 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added extra parameter, command identifier, to the
3611 silc_client_send_command so that explicit command identifier
3614 Changed that ID list routines uses specific command identifier
3615 when sending WHOIS/IDENTIFY requests to the server so that they
3616 can be identified when the reply comes back.
3618 Affected files lib/silcclient/command.[ch],
3619 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3621 * Added `sender' argument to silc_server_packet_send_to_channel
3622 to indicaet the sender who originally sent the packet to us
3623 that we are now re-sending. Ignored if NULL. Affected file
3624 silcd/packet_send.[ch].
3626 * Added some server statistics support in silcd/server_internal.h
3627 SilcServerStatistics structure and around the server code. Also
3628 send some nice statistics information when client is connecting
3631 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Fixed channel ID decoding in server's JOIN command reply in
3634 silcd/command_reply.c
3636 * Fixed braodcasting of replace ID payload to not to send it if
3637 we are standalone server in silcd/packet_receive.c.
3639 * Fixed all channel message sending routines to not to send
3640 packets to clients that has router set, since they are routed
3641 separately in the same function earlier. Affects file
3642 silcd/packet_send.c and all channel packet sending functions.
3644 * In USERS reply, res_argv[i] are not allocated, the table
3645 is allocated. Thus changed that free the table, not its
3648 * In server's whois_check and identify_check if the client is
3649 locally connected do not send any WHOIS commands - they are not
3652 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Fixed some minor bugs in client when sending WHOIS command. The
3655 arguments was in wrong order.
3657 * Removed statis function add_to_channel from server in
3658 silcd/command.c that was previously used with the joining but
3661 * Tested USERS command in router environment successfully with two
3662 routers, two servers and two clients.
3664 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Reorganized the USERS command and command reply in client library
3667 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3668 When the command is given by user we register a pending command
3669 callback that will reprocess the command after the reply has been
3670 received from the server. When reprocessing the packet we then
3671 display the information. Thus, the USERS information is displayed
3672 now in the command callback instead of in the command reply
3673 callback. The processing of the command is same as previously
3674 when server has sent the command reply in the JOINing process.
3676 * Added to USERS command in silcd/command_reply.c to join the client,
3677 we didn't use to know about, to the channel after we've created
3678 a client entry for it. Also, for clienet we did know already still
3679 check whether it is on the channel or not and add it if not.
3681 * Removed silc_server_command_join_notify as the function and its
3684 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Changed the client's pending command handling to the same as the
3687 server's pending command handling. It is also now possible to
3688 execute command reply functions from other command reply
3689 function as the function callbacks for commands and command
3690 replies are one and same. The pending commands are not static
3691 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3692 in client connection context. Thus, pending commands are server
3693 connection specific as it is convenient.
3695 Changed the function silc_client_command_pending and
3696 silc_client_command_pending_del and added new function
3697 silc_client_command_pending_check. Removed the
3698 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3701 * Added cmd_ident, current command identifier, to the client
3702 connection context in lib/silcclient/client.h to keep track on
3703 command identifiers used in command sending. Client's command reply
3704 function handling now supports the mandatory command identifiers.
3706 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3707 funtions in client to fully support pending command callbacks.
3709 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3710 as one of the arguments to the application in the command reply
3713 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3714 before first releasing SILC but came back. Now it is removed again
3715 and should come back nomore. The FORWARDED flag was used only
3716 by the JOINing procedure by forwarding the command packet to router.
3717 Now, the JOINing procedure has been changed to more generic (due
3718 to various router environment issues) and FORWARDED is not needed
3719 anymore for anything. The protocol specification is yet to be
3722 Now, removed silc_server_packet_forward from server and the flag
3723 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3725 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Renamed NAMES command to USERS command. The NAMES was named that
3728 due to historical reasons. Now it is renamed. Also, rewrote
3729 parts of the USERS command. The nickname list is not sent anymore
3730 by the server. Only Client ID and mode lists are sent in the USERS
3731 command. Changed this also to the protocol specification.
3733 The client now resolves the names and stuff after it receives
3734 the USERS list from the server when joining to the channel.
3736 * WHOIS and IDENTIFY commands has been changed to support multiple
3737 Client ID's per command. One can now search for multiple users
3738 in the network by sending only one WHOIS or IDENTIFY command.
3739 Changed the code and the protocol specifications.
3741 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3742 uses silc_server_command_whois_parse to parse the request. */
3744 * If normal server, do not parse the WHOIS and IDENTIFY requests
3745 before sending it to the router. Saves some time.
3747 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Fixed JOIN command on client library. Wrong number of arguments
3750 used to crash the client.
3752 * Added silc_server_channel_has_global function to check whether
3753 channel has global users or not.
3755 * Added silc_server_channel_has_local function to check whether channel
3756 has locally connected clients on the channel.
3758 * The silc_server_remove_from_one_channel now checks whether the
3759 channel has global users or not after given client was removed from
3760 the channel. It also checks whether the channel has local clients
3761 on the channel anymore. If it does not have then the channel entry
3762 is removed as it is not needed anymore.
3764 * The silc_server_notify now checks on JOIN notify whether the joining
3765 client is one of locally connected or global. If it is global then
3766 the channel has now global users on the channel and that is marked
3767 to the channel entry. Also, it now saves the global client to
3768 global list who is joining and JOINs it to the channel. This is
3769 for normal server, that is.
3771 Changed silc_server_send_notify_on_channel,
3772 silc_server_packet_relay_to_channel and
3773 silc_server_packet_send_to_channel check if we are normal server
3774 and client has router set (ie. global client) do not send the
3775 message to that client, as it is already routed to our router.
3777 * Implemented LEAVE notify type handling in silc_server_notify
3780 * Tested LEAVE command in router environment successfully. Tested
3781 with two routers, two servers and two clients.
3785 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3787 * Implemented SIGNOFF notify type handling in silc_server_notify
3790 * silc_server_remove_id now removes the client entry from all channels
3791 it has joined and thusly sends SIGNOFF notify type.
3793 * Rewrote the NAMES list generation in server by removing two excess
3794 loops. The lists are created now inside one loop.
3796 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * silc_server_remove_channel_user checks now also global list
3799 for channel and client.
3801 * silc_server_new_channel_user checks now both local and global
3802 list for channel and client. Fixed a bug in client id decoding.
3803 Used to decode wrong buffer.
3805 * silc_server_channel_message checks now both local and global
3806 list for channel entry.
3808 * Tested channel joining (hence JOIN) in router environment
3809 successfully. Tested with two routers, two servers and two
3812 * Tested channel message sending in router environment successfully.
3814 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Added silc_server_save_channel_key into server.[ch] to save the
3817 received channel key in Channel Key payload processing. It is
3818 also used in JOIN command reply handling.
3820 Equivalent function silc_client_save_channel_key added into
3821 client.[ch] into client library.
3823 * Changed JOIN command reply to send information whether the channel
3824 was created or not (is existing already) and the channel key
3825 payload. Changed protocol specs accordingly.
3827 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3828 the request was sent by ID and not by nickname. Crashed on
3831 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3834 now correctly save the received data.
3836 * silc_server_free_sock_user_data now notifies routers in the
3837 network about entities leaving the network.
3839 At the same time implemented functions silc_server_remove_id
3840 and silc_server_send_remove_id to receive and send REMOVE_ID
3841 packets. The packet is used to notify routers in the network
3842 about leaving entities. The ID removed will become invalid in
3845 * Added function silc_idlist_del_server into server. Removes and
3846 free's server entry from ID list.
3848 * silc_server_private_message function now checks, if we are router,
3849 that the destination ID really is valid ID, naturally.
3851 * In router when NEW_ID packet is received (for new client) the
3852 hash of the Client ID is saved in the ID Cache but the
3853 client->nickname is set to NULL, instead of putting the hash
3856 IDENTIFY command now also checks that client->nickname must be
3857 valid. If it is not if will request the data from the server who
3858 owns the client. Added new function
3859 silc_server_command_identify_check.
3861 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3862 to set the command to already allocated Command Payload.
3864 * Tested private message sending in router environment with two
3865 routers, two servers and two clients. Fixed minor bugs and now
3868 * Fixed segfault from client's NAMES command. Used to crash if
3871 * Forwarded packets must not be routed even if it is not destined
3872 to the receiver. Changed server code comply with this.
3874 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added `require_reverse_mapping' boolean value to ServerParams
3877 structure. If TRUE (not default) the server will require that
3878 the connecting host has fully qualified domain name.
3880 If the reverse mapping is not required and hostname could not be
3881 found the IP address is used as hostname.
3883 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Implemented version string checking to both client and server.
3886 The check is incomplete currently due to the abnormal version
3887 strings used in development version of SILC.
3889 * Changed all command functions in server to use the new
3892 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Changed char *data to unsigned char *data in ID Cache system to
3895 support binary data as ID Cache data. Changed code to support
3896 binary data in lib/silccore/idcache.c.
3898 * Renamed silc_server_packet_relay_command_reply to
3899 silc_server_command_reply as it is normal packet receiving
3900 function. Rewrote the function to accept command replys for
3901 servers and not only for clients.
3903 * Mark remote router always as registered server if we are connecting
3904 to it. Otherwise, commands sent by the router to us are ignored.
3906 * All ID List find routines now returns the ID Cache Entry pointer
3907 as well if requested.
3909 * WHOIS command works now in router environment, tested with two
3910 routers, two servers and two clients.
3912 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3913 in router environment (as it is almost equivalent to WHOIS) but
3914 hasn't been tested thoroughly. Added new functions:
3916 silc_server_command_identify_parse
3917 silc_server_command_identify_send_reply
3918 silc_server_command_identify_from_client
3919 silc_server_command_identify_from_server
3921 * Disabled route cache adding because adding two different ID's with
3922 same IP replaces the old cache entry thus giving wrong route.
3923 The entry->router->connection is always the fastest route anyway
3924 so route cache may not be needed. Of course, new routes maybe
3925 established after receiving the ID when the entry->router->connection
3926 might not be anymore the most optimal.
3928 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Add route cache for received ID for fast routing.
3932 * Added silc_server_packet_route to route received packet on router
3933 that is not destined to us.
3935 * Renamed silc_server_get_route to silc_server_route_get.
3937 * Added id_string and id_string_len fields into SilcServer to
3938 include encoded ServerID for fast comparing without excess
3939 encoding of the ID's.
3941 * Cleaned up WHOIS command on server side. Added following static
3944 silc_server_command_whois_parse
3945 silc_server_command_whois_check
3946 silc_server_command_whois_send_reply
3947 silc_server_command_whois_from_client
3948 silc_server_command_whois_from_server
3950 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3951 arguments in command replies. All command functions should be
3952 updated to use this macro.
3954 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Minor typo fixes on command reply handling on server.
3958 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Added silc_server_command_add_to_channel internal routine to add
3961 the client to the channel after router has created the channel and
3962 sent command reply to the server.
3964 * Added generic silc_server_send_command to send any command from
3967 * Use static buffer with ID rendering instead of duplicating data.
3969 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Fixed a channel user mode bug when joining to a channel server gave
3972 everybody channel founder rights, oops.
3974 * We mark ourselves as the router of the incoming server connection
3975 if we are router ourselves. This way we can check in some packet
3976 sending functions whether it is locally connected server. For
3977 incoming router connections we put NULL.
3979 * For router sending packets locally means now always sending the
3980 packet cell wide; to local clients and local servers. For normal
3981 server sending packet locally means sending it to only local
3984 * Fixed the JOIN command to really work in router environment. If the
3985 channel is created it is always created by the router. Router is
3986 also responsible of making the initial joining to the channel,
3987 sending JOIN notify to the sending server and distributing
3988 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3989 does not exist server doesn't do anything else but forward the
3990 command to the router which performs everything.
3992 * Added silc_server_send_channel_key function to send the Channel Key
3995 * Added silc_server_create_channel_key to create new channel key. The
3996 channel key is now re-generated everytime someone joins or leaves
3997 a channel, as protocol dictates. Note: channel->key_len is the
4000 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4003 packet_receive.[ch] to separate packet sending and receiving
4004 routines. The server.[ch] now includes everything else including
4005 actual packet processing (writing and reading data) and other
4008 Renamed silc_server_private_message_send_internal to
4009 silc_server_send_private_message. The routine is still though
4010 used only to relay private messages as server does not send
4011 private messages itself.
4013 Renamed silc_server_new_channel to silc_server_create_new_channel
4014 and added new function sicl_server_new_channel that handles the
4015 incoming New Channel packet. Added also new sending function
4016 silc_server_send_new_channel to send New Channel Payload.
4018 * Added new function silc_server_notify to process incoming notify
4019 packet to the server/router. Server may then relay the notify
4020 to clients if needed.
4022 * Added new function silc_server_new_channel_user to process incoming
4023 New Channel User packet. Router will redistribute the packet and
4024 send JOIN notify to its local clients and locally connected servers
4025 if needed. Normal server will send JOIN notify to its local client
4026 on same channel when received this packet. Added also corresponding
4027 sending function silc_server_send_new_channel_user to sent the
4030 * Added boolean route argument to send_notif_to_channel and
4031 packet_send_to_channel functions to attempt to route the packet
4032 if it is TRUE and send only locally if it is FALSE.
4034 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * silc_server_replace_id now broadcasts the received replace ID
4037 packet if it is not broadcast packet already. The router must
4038 broadcast to inform other routers about changed ID.
4040 * Added backpointer to server's router into SilcServer context in
4041 silcd/server_internal.h.
4043 * Fixed silc_server_packet_broadcast to send correct broadcast
4046 * The channel key is now distributed to the local client as soon
4047 as it is received from the router (in router environment) so that
4048 no other packet may be sent for the channel until client has
4051 * silc_server_remove_channel_user now broadcasts the received
4052 Remove Channel User packet if it is not broadcast packet already.
4053 The router must broadcast to inform other routers about removed
4056 * Added users field into SilcPacketContext that is a reference count
4057 of the context. One can increase the reference count by calling
4058 silc_packet_context_dup which is now changed to just increase the
4059 reference count instead of duplicating the data. The reference
4060 count is decresed by calling silc_packet_context_free that will
4061 free the data after the reference count hits zero.
4063 For now on the packet context and everything allocated into it
4064 (including the raw packet from network) must be freed by calling
4065 the new silc_packet_context_free function. Added also new function
4066 silc_packet_context_alloc that must be used now to allocate the
4067 context. This also means that if a routine is asynchronous from
4068 silc_[client/server]_packet_parse_type the packet context must
4069 be duplicated by calling silc_packet_context_dup. Otherwise it
4070 gets free'd after silc_[client/server]_packet_parse_type returns.
4071 Also, one must remember that if packet is duplicated then its
4072 reference count must be decresed by calling the free function as
4073 many times as it was duplicated.
4075 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4076 from both client and server.
4078 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Made joining to a channel working in router environment.
4082 * Cleaned up JOIN command on server side and create function
4083 silc_server_command_join_channel internal routine to make the
4086 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Changed silc_command_pending list to SilcDList. Also, added
4089 `ident' field to SilcServerCommandPending structure to identify
4090 the reply and to call correct callback.
4092 Added silc_server_command_pending_check function to replace the
4093 corresnponding macro. The silc_command_pending list is not
4096 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4097 to set identifier to previously allocated Command Payload. It
4098 is used to set identifier for command when resending Command
4101 * Added silc_command_payload_encode_payload to encode Command
4102 Payload buffer from SilcCommandPayload structure.
4104 * Added silc_argument_payload_encode_payload to encode Argument
4105 payload buffer from SilcArgumentPayload structure.
4107 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Changed WHOIS command to support router connection on server side.
4110 The whois request is always sent to router unless the server is
4111 standalone server. After server has received the reply from the
4112 router will it send the reply to the client.
4114 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4115 broadcast received broadcast packet. The function is used only
4116 by router. The broadcast packet is always sent to the router's
4119 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4120 render given ID to printable string, for log files for example.
4122 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Made basic router to router connections working. At least they
4125 can now connect to each other but nothing really works the way
4126 they are supposed - yet.
4128 * Added new initiator token to RouterConnection configuration
4129 file in silcd/serverconfig.[ch]. It is used to tell whether we
4130 are the initiator to the remote router or whether we'll expect
4131 the other end to connect.
4133 * Moved registering of listener task to silc_server_init, hence
4134 the server starts listenning as soon as it is run, even if it
4135 does not have connections to other routers. Let's see how well
4138 * Changed default connection retry timeouts for more suitable in
4141 * Removed cipher and such arguments from silc_idlist_add_client
4142 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4143 Added new function silc_idlist_add_data to add the keys and stuff
4146 * Added SilcIDListData structure and added it to SilcClientEntry
4147 and SilcServerEntry as their first field in the structure. This
4148 way we can explicitly cast the ID entries to the SilcIDListData
4149 structure and get common data for the entries. In past, we had
4150 to first check what type of connection it is and then cast it to
4151 correct ID entry type. Now, we can directly cast the opaque
4152 pointer to the SilcIDListData (no matter what ID entry it actually
4153 is) and get the data needed.
4155 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4158 in some circumstances even if threre were timeout tasks, though not
4159 IO tasks, but tasks anyway. Now fixed.
4161 * Defined SilcServerConnection structure to hold connection specific
4162 stuff about directly connected servers and routers. The definition
4163 is currently in silcd/server_internal.h. I thought about having
4164 a bit more important role fro this struct but for now it is used
4165 only when connecting to other server (or router actually).
4167 * Added connecting retry support in server when connecting to
4168 router(s). The retry feature implement exponential backoff
4169 algorithm. Also, added SilcServerParams structure to hold default
4170 parameters for server. For now, it include these retry settings
4171 and are hard coded. After server is moded to be as Silc Server
4172 Library this structure will be more important.
4174 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Changed client librarys channel->clients table to SilcList and
4177 changed code accordingly.
4179 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Changed client's channel table to SilcList and changed code
4182 accordingly. Also changed SilcChannelClientEntry to include back-
4183 pointer to the channel so that client entry can use that structure
4184 as list as well and we have fast cross-reference to the channel.
4185 This change dramatically decreased the complexity of channel
4186 handling with client entry and vice versa (removed one extra
4187 loop when searching for channel entry from many functions).
4189 * Changed server->sim from table to SilcDList and changed code
4192 * NAMES command can now be used from user interface. It will show
4193 the user list on the channel, neatly.
4195 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4196 Code now saves realname of the user if it becomes available.
4198 * Renamed configure.in to configure.in.pre and made ./prepare
4199 script to automatically add correct version string to
4200 configure.in which it creates from configure.in.pre.
4202 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * NAMES command reply now shows users mode with the nickname when
4207 * Moved silc_client_ch[u]mode[_char] functions from
4208 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4209 place sucks, they are utility functions and should be in some
4212 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4214 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4217 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Added TRQ (efficient deque and list library) into lib/trq. This is
4222 a very good list library that is currently used in the SILC. Defined
4223 SilcList API over the library because I didn't like the API very
4224 much. See lib/trq/silclist.h for the API and examples of how to
4225 use the API. Fixed various places in the code to use the new
4226 SilcList API. The SilcList is meant for lists that has a structure
4227 already defined as a list. It is not suitable to add just some
4228 context to the list (in TRQ, the context is the list actually).
4230 So, I defined SilcDList that can be used for the purpose where
4231 predefined list structure does not exit. This can be used as
4232 such list. Now some context just can be added to the SilcDList.
4233 Currently this list is not used in the SILC just yet, though there
4234 are a lot places where this can replace dynamically allocated
4235 tables and I will fix these places, later, to use SilcDList.
4236 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4237 and use TRQ internally).
4239 Also fixed some annoying warning messages that the original TRQ
4240 code generated. Also minor changes to TRQ's Makefile.in.
4242 * Added support for querying by Client ID to both WHOIS and
4243 IDENTIFY commands into server, as required by the protocol.
4245 * Removed method function pointers from SilcBuffer structure. They
4246 weren't used to anything and just increased the context size for
4247 no good reason. This change also made silc_buffer_alloc and
4248 silc_buffer_free functions inline functions.
4250 * Disabled command flooding detection support until it's fixed so
4251 that it accepts commands in but does not execute them more than once
4254 * Added silc_net_localhost(), to return local hostname, into
4255 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4256 that must be initialized before calling silc_client_init.
4258 * Added new function: silc_server_send_notify_on_channels to send
4259 notify messages to all channels client has joined. It is assured
4260 that the message is sent only once per client.
4262 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4263 lib/silcutil/silcutil.[ch] as silc_format function. The new
4264 function is generic and is used by server as well, not only by
4265 the logging routines.
4267 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4268 the provided version string was not acceptable. Added new function:
4269 silc_ske_check_version into lib/silcske/silcske.h. The function
4270 must be implemented by the application (client or server) and it
4271 does not reside in the SKE library. The function checks the version
4272 string remote end sent.
4274 * Added back pointers (to opaque context and to SilcSocketConnection)
4275 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4277 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4278 duplicate packet context structure.
4280 * Changed `notify' client operation to send same arguments as client
4281 receives from server except for ID's. ID's are mapped to correct
4282 ID entry and that is returned. Also, if channel entry is not sent
4283 by server but the notify is for channel the channel entry is sent
4284 to application (otherwise application doesn't know that it is for
4285 channel (library gets it from packet's Destination ID)).
4287 * Added silc_client_remove_from_channels into client library to
4288 remove a client from all channels it has joined to. Used when
4289 received SIGNOFF notify from server. Added also new function
4290 silc_client_replace_from_channels to replace old ID entry with
4291 new ID entry on all channels. Used when received NICK_CHANGE
4294 * Fixed ID Cache list handling in silc_idlist_get_client in
4295 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4296 to get (or query) client by ID.
4298 * Updated TODO list.
4300 * Added connection authentication status message defined by the
4301 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4302 support for these into the code in client and server side.
4304 * Added generic function silc_client_send_command to send any command
4305 with variable argument list. Application should use this function
4306 to send commands if the command functions provided by the library
4307 does not suite for the application's user interface needs.
4309 * Added new `failure' client operation. Application is notified about
4310 received failure packet if client is executing a protocol. In this
4311 case the protocol's execution has failed.
4313 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4314 is required by the protocol.
4316 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4317 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4320 * Added status flag to SilcSKE object to indicate realtime status
4321 of the SKE protocol.
4323 * Application receives now exactly same command reply arguments as
4324 the library receives from server. However, if ID is received the
4325 corresponding ID entry is returned to the application (eg. Client
4326 ID is mapped to correct SilcClientEntry entry and that is returned).
4327 Changed command_reply client operation due to this change.
4329 * Changed all ID's in commands and in command replys as ID Payloads.
4330 Change affected both client and server side codes.
4332 All ID's sent in SILC network (with execption of ID's in SILC
4333 Packet header) are sent in ID Payload to support variable length
4336 * Server now notifies nick changes and notifies all clients on
4337 the channels about the new nickname (about the new Client ID,
4340 * Implemented CMODE command to change channel modes. Supports all
4341 channel modes defined by the protocol specs except ban and invite
4342 lists. (Also, private channel key mode is supported but support for
4343 setting private channel key in client is missing, thus, this mode
4344 has no effect on client side (except that server requires that the
4345 client uses private channel key and normal channel traffic does not
4348 Also, invite mode works per se, but INVITE command does not work
4349 yet correctly, so you can set channel as invite only channel but
4350 inviting clients to the channel does not work (it is yet to be
4351 thought what's the best way to do it).
4353 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4354 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4355 Implemented CUMODE command to change user's mode on the channel.
4356 Supports all modes defined by the protocol specs.
4358 * Added NAMES command reply to return users modes on the channel.
4360 * Removed unnecessary and slow ciphers from lib/silccrypt.
4362 * Set SO_KEEPALIVE option to connection sockets by default.
4364 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4366 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4367 redefined the Notify Payload into protocol specs.
4369 * Added silc_id_payload_parse_id to get ID directly from raw
4372 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4375 accept searching by Client ID as well.
4377 * Added support for LEAVE and SIGNOFF notify types in client library.
4379 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4380 to parse ID Payload from raw data.
4382 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Added flags parameter into silc_ske_assemble_security_properties
4385 function in lib/silcske/silcske.[ch].
4387 * Changed notify client operation to fit better for notify messages
4388 sent by server. The notify payload received from server is now
4389 passed to the application (after parsing it to SilcNotifyPayload).
4390 It is application's responsibility to retrieve the arguments
4391 from the payload and show the message the way it wants. The message
4392 sent by server is implementation specific.
4394 * Changed public keys to comply with the protocol specification.
4395 Old public keys are not supported anymore and are not compatible.
4397 * Removed nickname from Channel Payload as the latest draft removed
4398 it. The client must resolve the nickname from the NAMES command
4399 reply received when it joined the channel.
4401 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4403 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Fixed some errors in protocol specification drafts.
4407 * Created lib/silccore/silcnotify.c to implement Notify Payload
4408 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4409 generic payloads described by protocol specifications. The file
4410 includes implementations for ID Payload and Argument Payload.
4412 * Changed Command Payload implementation to use the new Argument
4413 Payload. Changed command_xxxx_payload to command_payload_xxxx
4414 to comply with SILC coding conventions.
4416 * Added suppport for Argument Payload handling in Notify Payload
4417 implementation as protocol requires it. Added the new support
4418 into server and client lib as well.
4420 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added support for multiple nicknames on same channel. [n] is
4423 added locally to the nickname if there are more than one same
4424 nicknames on the channel.
4426 * Server now sends all nicknames that matched WHOIS request.
4427 Client also shows the list received from server.
4429 * Added TOPIC command to client side. User can now set and show
4430 current topic on channel.
4432 * Added MOTD command to client and server. Also, server sends the
4433 motd when client connects to the server.
4435 * Changed version strings to comply ISO 8601.
4437 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Fixed protocol error handling in client library. It should now
4440 cope even if the SKE fails for some reason.
4442 * Made new protocol specification drafts for submitting to IETF.
4444 * Implemented TOPIC command to server in silcd/command.c.
4446 * Added two new notify types into lib/silccore/silcnotify.h:
4447 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4448 notify nickname change and topic setting/change on a channel.
4450 * API change of command_reply operation in client library. The
4451 application gets now the status type received from server as well.
4453 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4457 * Cras fixed and optimized the packet handling even further and
4458 it should work now. Minor change to the prototype of function
4459 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4461 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added new function into lib/silcutil/silcschedule.[ch]:
4464 silc_schedule_with_fd to select() a specified fd. The function
4465 returns after timeout expires or data arrives or goes. The
4466 function is used by packet routines to wait that all data is
4467 received from network.
4469 * Fixed data reading from network in lib/silccore/silcpacket.c.
4470 The code now assures that all data is read from the fd and then
4471 continues packet processing. This was a bug fix since the code
4472 used to drop some data in some circumstances.
4474 * Added new function into lib/silcclient/client.[ch]:
4475 silc_client_start_key_exchange to start key exchange after
4476 connection has been established to server. The code internally
4477 now uses this funtion but its main purpose was to provide it
4478 for applications that perform their own connecting. After
4479 application has created a connection it merely calls this
4480 function to start the key exchange between client and server.
4481 The library takes care of everything else after that.
4483 Updated also lib/silcclient/README to explain the usage of
4486 * Do not send to application information that connection has
4487 been established. Application gets notified it by connect
4490 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Applied cras's patch to add silc_schedule_one function. The
4493 function runs scheduler once and returns.
4495 * Fixed the scheduler after cras messed it up. The timeout
4496 handling works now as it's supposed to work.
4498 * Added into lib/silccore/ silcnotify.h to include notify
4499 message types support. Changed silc_server_send_notify*
4500 functions, in server.[ch], to support those new notify types.
4501 Added the support for the notify types into client library,
4502 as well. Added new notify client operation into ops.h in
4505 * Changed silc_server_packet_send_to_channel to send normal
4506 packets instead of just channel message packets. The function
4507 is now used to send the notify packets to channels. It is not
4508 used to send channel message packets anymore, as server never
4511 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4512 va_arg()s as it seems to require it nowadays. I guess, if SILC
4513 is compiled with older va_arg() the new code should work anyway.
4515 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Splitted core library. Core library (lib/silccore) includes
4518 now only SILC protocol specific core (and common) components.
4519 Created new utility library (lib/silcutil) that includes more
4520 generic purpose stuff. The stuff for util library was taken
4521 from the old core library. This was minor and easy split.
4523 * Created SILC Client Library (lib/silcclient) that includes
4524 implementation of the SILC client without user interface. This
4525 was major move from silc/ directory. The code has been changed
4526 so that it is transparent towards the user interface. The
4527 silc/ directory includes now the same user interface as before
4528 and it uses the new client library. Read lib/silcclient/README.
4529 Basicly, the client library performs everything else related
4530 to SILC except user interface handling. Also, configuration
4531 files are considered to be part of user interface and library
4532 does not handle them.
4534 This change also changed a lot of structures, function naming etc.
4535 Most important change was that SilcClientWindow object was
4536 renamed to SilcClientConnection in the client library. Created
4537 also new file lib/silcclient/ops.h. Also added new files
4538 silc/local_command.[ch] and silc/client_ops.[ch].
4540 All these changes were made to make it easier for user interface
4541 designers to create what ever user interface for the SILC client
4544 It is also expected that the server will be moved to lib
4545 directory as well and SILC Server Library will be created;
4546 sometimes in the future.
4548 * Removed Local commands from lib/silccore/silccommand.h as
4549 they are application specific and new client library does not
4550 handle any of those anymore.
4552 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4553 old client implementation in silc/.
4555 * Added support for callback functions in SILC_LOG_* macros.
4556 Application can now set its own callbacks that will be called
4557 instead of using the default functions that will always print
4558 the debug messages to stderr (or stdout). Also, debugging can
4559 now be disabled by setting silc_debug to FALSE and re-enabled by
4560 setting it to TRUE. Note, that logging will still work even
4561 if debugging is disabled.
4563 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4564 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4565 silc_log_reset_debug_callbacks.
4567 * To enable debugging in silc client one must give now -d
4568 option on command line.
4570 * Changed silc_schedule_init to automatically allocate task queues
4571 if they are not allocated before calling it.
4573 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added GMP 3.1 into math library.
4577 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4580 a channel in SILC network. The packet is used by servers and
4581 routers to notify other routers that user has left a channel.
4582 This little feature was missing until now. Added the feature
4583 to protocol specification as well.
4585 Added functions: silc_server_send_remove_channel_user and
4586 silc_server_remove_channel_user into server.[ch].
4588 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4589 lib/silccore/silcpacket.h. However, they are not implemented
4592 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Fixed joining to a channel and sending channel messages
4595 between server and router. The channel message sending should
4596 now work inside a cell.
4598 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Fixed the private message sending between server and router.
4601 The private message sending should now work inside a cell.
4603 * Added silc_server_replace_id into server.[ch] to replace
4604 existing ID in the SILC network.
4606 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4607 and silc_idlist_replace_server_id into idlist.[ch] in server.
4609 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Fixed the server to server connections. Server can again now
4612 connect to router. Router to router connections probably does
4615 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added dynamic protocol registering support. Now protocols can
4618 registered and unregistered on the fly. Patch by cras.
4620 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added lib/contrib directory to hold routines that some platforms
4623 don't have but are needed by SILC.
4625 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4626 into lin/contrib to provide getopt() and getopt_long() for
4627 those who don't have it.
4629 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added AWAY command to client. When away message is set and
4632 client receives a private message packet the client automatically
4633 replies to the sender with the away message.
4635 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4636 bug seemed to be the cause of recent problems when compiling
4639 * Added version detection support to SKE protocol specification
4640 and added the new changes to the SKE implementation as well.
4641 There were other minor changes in the SKE protocol as well.
4643 Many changes in lib/silcske/silcske.[ch] and in
4644 lib/silcske/payload.[ch].
4646 * Added ^U functionality, clear input line. Patch from cras.
4648 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Mainly small bugfixes on core library. Fixed some debugging
4651 logging and buffer overflow in silclog.c.
4653 * Updated config.sub and config.guess on the distribution tree.
4655 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added command lagging support in server. Client may execute
4658 commands now only once in two seconds.
4660 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Optimized packet reception. MAC computation and checking is now
4663 also more optimized. A lot previously duplicated code is now
4664 used as generic by both client and server.
4666 * Fixed key pair generation in clientutil.c
4668 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Added into lib/silccore/silcbufutil.[ch] new function;
4671 silc_buffer_realloc.
4673 * Moved generic packet sending/encryption functions to
4674 lib/silccore/silcpacket.[ch] from client and server. Some
4675 rewriting of the functions.
4677 * Moved all generic packet reception/decryption functions to
4678 lib/silccore/silcpacket.[ch] from client and server. The
4679 packet processing is now much cleaner in both client and server.
4680 These were major changes in both client and server.
4682 * Created many common functions in server to do packet sending.
4683 Previously code were duplicated a lot, this has been removed
4686 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Rewrote major parts of the ID cache system. Don't know
4689 whether it is better now or not but at least the API is more
4692 * Major rewrite on ID cache stuff on client because of the ID
4693 cache API changes. Added idlist.c to client.
4695 * Also major rewrite on ID cache stuff on server as well.
4696 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4697 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4698 in hand, instead they are all put into the ID cache system now.
4699 All server_idlist_* routines uses ID cache now instead of
4700 traversing its own lists (those lists does not exist anymore).
4701 SilcIDList though still exists. Also, SilcXXXEntry's are
4704 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Finally made the SKE implementation compliant to the protocol
4707 specification. All mp integers are now binary encoded as
4708 opposed being HEX encoded.
4710 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4713 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4714 functions: silc_[encode/decode]_pem. Also added function
4715 silc_encode_pem_file to PEM encode with newlines ('\n') for
4718 * SILC public keys are now encoded either PEM or binary. Same
4719 option is for private keys as well. By default private keys
4720 are binary encoded and public keys PEM encoded. Silly HEX
4721 encoding were removed.
4723 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4724 function to create fingerprints.
4726 * Fixed a bug in SHA1; does not change the original data anymore.
4728 * Partly implemented INFO command on client and server side.
4729 Fixed CLEAR command. Changes to SERVER command; show current
4730 server(s) when giving command without arguments. Added
4731 VERSION command to client.
4733 * Added check to server that unregistered connections cannot
4734 execute commands (unless it is specificly allowed).
4736 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Fixed screen refresh.
4740 * Fixed channel joining bug from client. On some circumstances
4741 client tried to join to a channel it had already joined.
4743 * Added public key verification process into client's protocol.c.
4744 The client now verifies the public key from user and saves
4745 it into ~./silc/serverkeys/ directory.
4747 Added into: clientutil.[ch]: silc_client_verify_server_key.
4749 * Changed SKE protocol's silc_ske_initiator_finish function
4750 to accept callback function that verifies the received public
4751 key. Removed old silc_ske_verify_public_key function.
4753 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4756 silc_pkcs_private_key[_data]_set.
4758 * Made the password and public authentication more cleaner in
4759 server's protocol.c.
4761 * Removed historic and obsolete protocol `channel_auth' from
4762 both client and server.
4764 * Removed wrong way of sending command status messages from
4765 server to client in server's command.c. The old way violated
4766 protocol specification.
4768 Changes to silccore/silccommand.[ch]: removed
4769 silc_command_encode_status_payload -> not needed anymore,
4770 changed silc_command_encode_payload_va to accept extra
4771 argument on variable argument list. The argument type must
4772 now be provided to the function. Also, added new function:
4773 silc_command_encode_reply_payload_va which is same as
4774 normal command_encode_payload_va except command status type
4775 is provided as extra argument.
4777 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added ~./silc directory handling. The directory includes the
4780 public and private keys for the client.
4782 Added silc_client_check_silc_dir, silc_client_create_identifier
4783 and silc_client_load_keys.
4785 * Implemented SILC protocol compliant public key. Added public
4786 and private key saving to and loading from files.
4788 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4789 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4790 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4791 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4792 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4794 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4795 silc_pkcs_load_[public/private]_key.
4797 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Added silc_server_get_route (route.[ch]) to get connection
4800 data for the fastest route for given ID.
4802 * Implemented INVITE command on client and server. The command
4803 were re-defined in the SILC Protocol Specification and the
4804 implementation now complies with the specification.
4806 * Implemented PING command on client and server.
4808 * Implemented NAMES command on client and server. The server side
4809 supports currently only normal server not router server yet.
4810 Some changes to NAMES definition in SILC protocol specification.
4812 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Implemented LEAVE command on client and server.
4816 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4817 again. This change was made to the protocol as well. Server
4818 should not violate the protocol specification anymore.
4820 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4823 was tested. SOCKS4 was not but should work anyway.
