1 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added some SILC_LOG_ERROR's to various error conditions
4 if client could not be added to ID cache. Affected files
5 silcd/packet_receive.c and silcd/server.c.
7 * When client's sock->user_data is freed, NULL also the
8 client->router and client->connection pointers. Added check
9 for these pointers being NULL to various places around the
10 code. Affected file silcd/server.c.
12 * Added client->data.registered == TRUE checks to various
13 places around the code to assure that unregistered client's
14 are not handled when it is not allowed. Affected file
17 * Added `bool registered' fields to all
18 silc_idlist_[server|client]_get_* routines to indicate whether
19 the fetched client needs to be registered or not. Affected
20 file silcd/idlist.[ch].
22 * Add your own entry as registered to the ID cache in the
23 server. Affected file server.c.
25 * Fixed a bug in silc_server_new_server. The SilcServer was
26 set as the new server's context instead of SilcServerEntry.
27 This naturally caused some weird bugs.
29 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
31 * Do not delete the channel rekey task when adding it
32 for in silc_server_create_channel_key.
34 * Changed the silc_server_create_channel_key to return
35 TRUE or FALSE to indicate the success of the channel key
38 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
40 * Fixed MSVC++ project files and added missing files to
41 Makefiles under win32/.
43 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Do not add TCP_NODELAY flag if the operating system
46 does not have it defined. Affected files are
47 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
49 * Fixed buffer overflow from Irssi SILC Client. Affected
50 file irssi/src/fe-common/core/themes.c.
52 * Fixed double free in client library in the file
53 lib/silcclient/client.c when disconnecting from server.
55 * Applied double free patch from cras to Irssi SILC client.
56 Affected files irssi/src/core/[modules/expandos].c
58 * Fixed the disconnection handling to Irssi SILC Client.
59 The application must call silc_client_close_connection
60 in ops->connect client operation in case of failure of
61 the connection. Affected file is
62 irssi/src/silc/core/client_ops.c.
64 * Do not set sock->protocol to NULL in the function
65 silc_client_close_connection after executing the protocol's
66 final callback since the sock might not be valid anymore.
67 Affected file lib/silcclient/client.c.
69 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
71 * Do not enable SILC_THREADS if the linking with libpthread
72 did not happen. Affected file configure.in.pre.
74 * Added notion to protocol specification that server must
75 verify the sent authentication payload with CMODE when
76 setting the channel founder key. Implemented it to the
77 server. Affected file silcd/command.c.
79 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
81 * Added _EXTRA_DIST SILC distribution variable to the
82 distributions file. It is used to conditionally add extra
83 files or directories to the specific distribution. Affected
84 files ./prepare, Makefile.am.pre and distributions.
86 Removed the `_' from the start of the distribution names.
89 * Added README.WIN32 for instructions to compile the Toolkit
92 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed a double free in disconnection in the server. Affected
95 file is silcd/server.c.
97 * Fixed the lib/silcske/groups.c to work now also with GMP
98 MP library. The string conversion did not work when using
99 specific base and the base is indicated in the string as well.
101 * Created win32/ directory which now includes MSVC++ specific
102 stuff so that toolkit (DLLs) may be compiled with MSVC++.
103 It will appear only in the toolkit distribution
105 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
107 * Changed the key material distribution function in case when
108 the hash output is too short. The data is now concatenated
109 a bit differently than it used to. Made the change to the
110 SKE protocol specification.
112 * Added better GMP detection to configure.in.pre. A patch
115 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
117 * Fixed a minor bug in SKE that might cause some problem on
118 some platforms. Affected file lib/silcske/silcske.c.
120 * Added the cookie checking for initiator in the SKE. It checks
121 that the responder returns the sent cookie unmodified. The
122 affected file is lib/silcske/silcske.c. Added new SKE
123 error type INVALID_COOKIE that can be sent during the
124 negotiation. Fixed some memory leaks as well.
126 * Added the "invalid cookie" error message to Irssi SILC client's
129 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
131 * Added `task_max' field to the SilcClientParams to indicate
132 the maximum tasks the scheduler can handle. If set to zero,
133 default values are used. Affected file lib/silcclient/silcapi.h.
135 * Fixed memory leaks in silc_client_close_connection. Affected
136 file lib/silcclient/client.c.
138 * Added silc_client_del_client_entry to client library to free
139 all memory of given client entry. Affected file is
140 lib/silcclient/idlist.[ch].
142 * Added new functions silc_client_del_channel and
143 silc_client_del_server to delete channel and server entries.
144 Affected file lib/silcclient/[silcapi.h/idlist.c].
146 * Removed silc_client_del_client_by_id from silcapi.h.
148 * Fixed the INFO command to return the server's own info
149 correctly when querying by Server ID. Affected file is
152 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Removed the non-blocking settings in WIN32 code in the
155 silc_sock_[read/write] and added SleepEx instead. Affected
156 file lib/silcutil/win32/silcwin32sockconn.c. The availability
157 of input data is now checked with FIONREAD and ioctlsocket.
159 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
161 * Call silc_schedule_task_del_by_context in the
162 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
163 Affected file lib/silccore/silcprotocol.c.
165 * Call silc_protocol_cancel for active protocols in the
166 silc_server_close_connection if the funtion
167 silc_server_free_sock_user_data has not been called.
168 Affected file silcd/server.c.
170 * Generic tasks cannot be deleted using the del_by_fd
171 task deleting function since generic tasks does not match
172 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
174 * Added a notion to SILCOPER help file that the SILCOPER works
175 only on router server, not on normal server.
177 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Added for WIN32 support for the new scheduler as well.
180 Affected file lib/silcutil/win32/silcwin32schedule.c.
182 * Fixed the SHA1 implementation to work on various platforms.
184 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
186 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
187 API. It is part of the scheduler now. Everything else is
188 as previously but some functions has changed their names.
189 Checkout the lib/silcutil/silcschedule.h for the interface.
190 Updated all applications to use the new interface. Affected
191 files are lib/silcutil/silcschedule.[ch].
193 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
195 * Found a bug in the SKE implementation. The HASH value,
196 specified by the protocol, was not computed correctly. The
197 public key of the responder was not added to the computation
198 even though it is mandatory. Affected file lib/silcske/silcske.c.
199 This unfortunately causes incompatibilities with older
202 * Added WIN32 specific network init and uninit functions:
203 silc_net_win32_init and silc_net_win32_uninit to init and uninit
204 the Winsock2. Affected file lib/silcutil/silcnet.h and
205 lib/silcutil/win32/silcwin32net.c.
207 * Set the socket always to nonblocking mode on WIN32 after
208 reading data or writing data. Affected file is
209 lib/silcutil/win32/silcwin32sockconn.c.
211 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
213 * Fixed various compilation problems under WIN32. Affected
214 files lib/silcutil/win32/silcwin32thread.c and
215 lib/silcutil/win32/silcwin32schedule.c.
217 * Removed all _internal.h #includes from public header
218 files. Internal headers must never be included from
221 Removed also the lib/silcske/payload_internal.h file.
223 * All include files that may be needed (public and some others
224 included by the public headers) by application developers are
225 now copied to the ./includes directory. It does not copy any
226 internal headers. Affected file Makefile.defines.pre and all
227 Makefile.am's under lib/ and subdirs.
229 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
231 * Do not change the ~/.silc directory's permissions automatically.
232 Affected file irssi/src/silc/core/clientutil.c.
234 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
236 * Do not cancel the protocol in silc_server_close_connection
237 it might cause recursion. Now cancelled in the function
238 silc_server_free_sock_user_data. Affected file silcd/server.c.
240 * Fixed the silc_server_remove_clients_by_server to regenerate
241 the channel keys correctly finally. Added also new function
242 silc_server_remove_clients_channels to actually do it.
243 Affected file silcd/server.c.
245 * Fixed the silc_server_new_channel to not crash by giving
246 wrong router to the new channel. Affected file is
247 silcd/packet_receive.c.
249 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
251 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
252 which is given as argument to the silc_client_alloc now.
253 It can be used to configure the client and set various parameters
254 that affect the function of the client.
256 * The USERS command in server did not check whether the channel
257 is private or secret. Affected file silcd/command.c.
259 * Added new argument to the USERS command in protocol specification.
260 The USERS command now can take the channel name as argument
261 as well. Added support for this in client and server and
262 updated the protocol specs.
264 * Completed the GETKEY command in client. It can be now used
265 to fetch also servers public key not only some clients.
266 Affected files lib/silcclient/command[_reply].c.
268 * Added silc_client_get_server to return server entry by the
269 server name. Affected files lib/silcclient/silcapi.h and
272 * Redefined the IDENTIFY command in protocol specification to be
273 more generic. It now can be used to query information about
274 any entity in the SILC Network, including clients, servers and
275 channels. The query may be based either the entity's name
276 or the ID. Added support for this in both client and server.
278 Affected files silcd/command.c and lib/silcclient/command.c
281 * Optimized the WHOIS and WHOWAS commands in the server. Removed
282 the _from_client and _from_server functions. Affected file
285 * Added silc_client_get_channel_by_id_resolve to the file
286 lib/silcclient/silcapi.h to resolve channel information by
287 its ID. Added also silc_client_get_channel_by_id that
288 does not resolve it from the server.
290 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
292 * Added SilcServerEntry context into the client library
293 to represent one server. The INFO command now allocates
294 these to save the resolved server info. For now on the
295 client library will also keep information about servers,
296 connected and resolved with INFO.
298 The INFO command now allocates the SilcServerEntry context
299 and saves the server info there. The COMMAND_REPLY in
300 the INFO now returns the parameters to application in
301 same order as defined in the protocol specification.
303 The entries are cached in the client->server_cache.
305 * The INFO command is now issued after received the Client ID
306 from the server. Affected file lib/silcclient/client.c.
308 * The CMODE_CHANGE notify may now return also an SilcServerEntry
309 to the application as the mode changer might be server.
310 It is guaranteed that NULL is not returned anymore to the
311 application. Affected file lib/silcclient/client_notify.c.
313 The ID Type is now also passed to the application so that
314 it can check whether the returned entry is SilcClientEntry
317 Added new function silc_client_get_server_by_id to return
318 the server entry by ID. Affected files are the
319 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
321 * Do not create the channel in the Irssi SILC Client when issuing
322 the JOIN command but when received the sucessful JOIN command
323 reply. Otherwise the channel might get created even though we
324 could not join it. The Affected file is
325 irssi/src/silc/core/[silc-channels.c/client_ops.c].
327 * Fixed a channel joining bug in router. The router must also
328 check the channel modes, invite and ban lists etc. when serving
329 the JOIN command sent by normal server. Affected file is
330 silcd/command.c. The router now resolves the client's
331 information from the server who sent the JOIN command if it
332 does not know it, and processes the JOIN command only after
335 * Changed the SilcCommandCb to take new argument; void *context2.
336 Affected file lib/silccore/silccommand.h
338 The second argument in the command callbacks in the server now
339 includes the SilcServerCommandReplyContext if the command was
340 called as pending command callback from the command reply.
341 Otherwise it is NULL. When called as pending the status of the
342 command reply will be checked and if it was erronous the
343 error will be sent to the original sender of the command.
344 This way the client always receives the error messages even
345 though the server was actually the one who received the error
346 when it resent the command to router, for example. Affected
347 files silcd/command[_reply].[ch].
349 * Fixed sending WHOWAS command's error message to client if
350 the requested client could not be found. It was missing.
353 * Changed the CMODE and CUMODE commands reply arguments in the
354 protocol specification. The Channel ID is now sent in both
355 of the commands to identify the channel. Implemented this
356 new feature to the client and server. Affected files
357 lib/silcclient/command_reply.c and silcd/command.c.
359 * Made better checks for invite and ban lists in the JOIN
360 command in server. Affected file silcd/command.c.
362 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
364 * The server now performs the incoming host IP/DNS lookup
365 using the silc_socket_host_lookup and thus does not block
366 the server anymore. Affected file silcd/server.c.
368 * Completed the multi-thread support for SILC Scheduler in
369 the lib/silcutil/silcschedule.c.
371 * Fixed the configure.in.pre to detect the pthread correctly
374 * Fixed a deadlock in silc_task_queue_wakeup in the file
375 lib/silcutil/silctask.c.
377 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
379 * Added new function silc_schedule_wakeup that is used in
380 multi-threaded environment to wakeup the main thread's
381 schduler. It needs to be used when a thread adds a new task
382 or removes a task from task queues. After waking up, the
383 scheduler will detect the task queue changes. If threads
384 support is not compiled in this function has no effect.
385 Implemented the wakeup mechanism to both Unix and WIN32
386 systems. Affected files are lib/silcutil/silcschedule.[ch],
387 lib/silcutil/unix/silcunixschedule.c and the
388 lib/silcutil/win32/silcwin32schedule.c.
390 * Added new function silc_task_queue_wakeup to wakeup the
391 scheduler by the specified task queue. Affected file
392 lib/silcutil/silctask.[ch].
394 * The silc_socket_host_lookup_start now wakes up the scheduler
395 after adding the timeout task. Affected file is
396 lib/silcutil/silcsockconn.c.
398 * The silc_socket_host_lookup is synchronous now if the threads
399 support is not compiled in. However, the callback is still
400 called asyncronously through the scheduler, anyway. Affected
401 file lib/silcutil/silcsockconn.c.
403 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Added new function silc_socket_host_lookup to perform
406 asynchronous IP and FQDN lookups for the socket connection.
407 Affected files lib/silcutil/silcsockconn.[ch].
409 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
411 * Added SILC_MUTEX_DEFINE to define the mutex on environments
412 that may or may not compile the mutex support in.
414 Changed the silc_mutex_alloc interface. It allocates the
415 mutex now to the sent pointer and returns TRUE or FALSE.
417 Affected file lib/silcutil/silcmutex.h.
419 * Wrote the SILC Task Queue interface to support multi-threads.
420 Affected file lib/silcutil/silctask.[ch].
422 * Wrote the SILC Scheduler to support multi-threads. Affected
423 file lib/silcutil/silcschedule.c.
425 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
427 * Implemented the SILC Mutex API and SILC Thread API for WIN32
428 in lib/silcutil/win32/.
430 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
432 * Defined SILC Mutex API and SILC Thread API and implemented
433 them for Unix. Affected files are
434 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
435 lib/silcutil/unix/silcunixmutex.c and
436 lib/silcutil/unix/silcunixthread.c.
438 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Fixed the silc_server_remove_clients_by_server's channel
441 key re-generation. The hash table handling was incorrect
442 and would not work with many channels. Affected file is
445 * Fixed some memory leaks around the server code.
447 * Rewrote the silc_server_get_users_on_channel to support IPv6
448 based Client ID's. Affected file silcd/server.c.
450 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
451 specification. However, a separate document must be written
452 to define the detailed signing procedure and the payload
453 associated with the flag. Defined the flag to the
454 lib/silccore/silcchannel.h as well.
456 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Changed the dynamic tables to static size tables in the
459 lib/silccrypt/silchmac.c.
461 * Removed GCC dependencies from the code. A patch by cras.
463 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Do not show the error "Error receiving packet bla bla"
466 in server if it really was not an error (-2 means that reading
467 is pending). Affected file silcd/server.c.
469 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
471 * Fixed a possible crash in silc_server_remove_clients_by_server
472 in silcd/server.c. Fixed there also some memory leaks.
474 * Fixed the silc_idlist_replace_client_id. It could replace
475 wrong key in the hash table. Affected file silcd/idlist.c.
477 * Do not check whether there are global users on the channel
478 if the channel->global_users is FALSE. Affected functions
479 silc_server_remove_from_one_channel and
480 silc_server_remove_from_channels in silcd/server.c. Also,
481 do not check if the removed client is local as we can be
482 sure that global client was not removed from the channel
483 and checking for global users is not needed.
485 * The silc_server_remove_clients_by_server now re-generates
486 the channel keys correctly for those channels that had
487 clients removed from them. Affected file silcd/server.c.
489 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
491 * Found the reason of random crashes in the server. We weren't
492 ignoring the SIGPIPE signal (which can be sent in write())
493 and it crashed the server. Affected file silcd/silcd.c.
495 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
497 * Assure that sock->user_data is not NULL in the function
498 silc_server_packet_send in silcd/packet_send.c.
500 * Disconnect the remote connection if it could not be added
501 to any ID lists in the server. The affected file is
504 * Check in silc_server_packet_send[_real/dest] that the
505 socket is not disconnecting and ignore the data if it is.
506 Affected file silcd/packet_send.c.
508 * Define inline to __inline on native WIN32 compilation.
509 Affected file includes/silcwin32.h.
511 * Added some explicit type casts for inline code since MSVC
512 require them. Affected files lib/silcutil/silcbuffer.h,
513 lib/trq/silcdlist.h and lib/trq/silclist.h.
515 * Print warning in log files from now on if the packet
516 decryption fails. Affected file silcd/server.c.
518 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
520 * Changed the `say' client operation's interface to accept
521 new `type' argument to indicate the type of the message sent
522 by the library. The application may filter the library's
523 messages according the type. The affected file is the
524 lib/silcclient/silcapi.h.
526 * Added two new functions to lib/silcclient/silcapi.h:
527 silc_client_del_client and silc_client_del_client_by_id.
528 Affected file lib/silcclient/idlist.c.
530 * Moved the clientincludes.h from includes/ to silc/ and
531 serverincludes.h from includes/ to silcd/.
533 * The modes for the CMODE and CUMODE are now passed as
534 uint32 for application with COMMAND_REPLY. The affected
535 file is lib/silcclient/command_reply.c.
537 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
539 * /WHOIS without arguments shows client's own information.
540 Affected file lib/silcclient/command.c.
542 * Changed PING to not accept any arguments. The specs
543 says that client can ping only the connected server so
544 requiring an argument is not needed. Affected file is
545 lib/silcclient/command.c.
547 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Fixed a fatal bug in private message sending and reception
550 encryption and decryption when using private message keys.
551 The implementation was incorrect and did not follow the
552 specification. It causd that some of the message were
553 lost since it did not use the sending and receiving keys
554 as the protocol suggests. This has been fixed and will cause
555 incompatibilities with older clients when sending private
556 message encrypted with private message keys. Affected files
557 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
558 and various other in Irssi SILC Client.
560 Added `responder' boolean argument to the functions
561 silc_client_add_private_message_key[_ske] to indicate when
562 the key is added as responder or initiator of the key
565 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Removed the silc_ske_check_version function and created
568 a SilcSKECheckVersion callback. Added also a function
569 silc_ske_set_callbacks that is now used to set all SKE
570 callbacks. The callback functions are not given to
571 the SKE functions anymore, but this function is used to
574 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
576 * Added `silc_version' argument to the silc_client_alloc
577 to define the version of the application for the library.
578 The library will use the version string to compare it
579 against the remote host's (usually a server) version
580 string. Affected file lib/silcclient/silcapi.h
582 * Added the KE protocol context to Key Agreement context
583 in client library so that we can abort the SKE if it
584 is in process when we get timeout. Affected file is
585 lib/silcclient/client_keyagr.c.
587 * Do not resolve the client ID forever if it returns in the
588 first time that such client does not exist. This was done
589 for example with private message. Affected file is
590 lib/silcclient/client_prvmsg.c.
592 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
594 * Do not add regex.h for WIN32. The affected file
595 includes/silcincludes.h.
597 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
598 not work yet 100%. It generates the DLL's automatically
599 when compiling with --with-win32 under cygwin.
601 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
603 * lib/contrib/regex.c is not compiled on WIN32.
605 * Added silc_net_get_socket_opt function to the
606 lib/silcutil/silcnet.h.
608 * Added includes/silcwin32.h for WIN32 specific includes
611 * Do not use ptime structure or any of the posix process
612 functions on WIN32 in lib/silccrypt/silrng.c.
614 * Added silc_gettimeofday to provide generic function
615 for struct timeval on all platforms. Added the function
616 to lib/silcutil/silcutil.h.
618 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Moved the lib/silccore/silcsockconn.[ch] to the utility
621 library as they clearly belong there. As a plus side we
622 can make the actual socket connection routines platform
625 Added also new generic function silc_socket_read and
626 silc_socket_write (that used to be silc_packet_[read/write].
627 The implementation of these are platform specific.
629 * Added WIN32 specific routines of silc_socket_[read/write]
630 to lib/silcutil/win32/silcwin32sockconn.c.
632 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Added preliminary support for native WIN32 compilation under
635 cygwin (using the -mno-cygwin option for GCC) to the
636 ./configure.in.pre. The --with-win32 now prepares the
637 compilation for native WIN32.
639 * Rewrote the SILC Scheduler interface in the file
640 lib/silcutil/silcschedule.h. The scheduler is now context
641 based and does not have anymore any global static scheduler.
642 Moved the Unix scheduler to the lib/silcutil/unix/ directory
643 and created lib/silcutil/win32 directory for WIN32 based
646 * Added Unix specific network routines to the
647 lib/silcutil/unix/silcunixnet.c and the old
648 lib/silcutil/silcnet.c includes now only generic routines.
650 Added WIN32 specific network routines to the
651 lib/silcutil/win32/silcwin32net.c.
653 * Added Unix specific utility functions from the
654 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
656 * Added WIN32 SILC Scheduler to the file
657 lib/silcutil/win32/silcwin32schedule.c. The code is of course
660 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Do not handle JOIN notify in the server if the target client
663 is not registered (idata->registered == FALSE). The affected
664 file is silcd/packet_receive.c.
666 * Update the nickrec->founder in event_cumode in the Irssi SILC
667 client. Affected file irssi/src/silc/core/silc-channels.c.
669 * Fixed the CUMODE_CHANGE notify handling in the server when
670 server and router are announcing their clients on channels.
671 Now the mode changes are saved and notified correctly. The
672 affected file is /silcd/packet_receive.c.
674 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
675 They really did not replace the cache entry in the ID Cache.
676 Now they do that. Affected file silcd/idlist.c.
678 * Fixed the KICK notify handling in the Irssi SILC client to
679 update the channel records so that the kicked client does not
680 appear to be on the channel. The affected file is
681 irssi/src/silc/core/silc-channels.c.
683 * Always update the conn->current_channel when executing command
684 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
686 * Fixed the KILL notify handling in Irssi SILC client to remove
687 the killed client on all channels.
689 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Fixed the silc_parse_command_line to remove extra spaces
692 from the start and end of the arguments. Affected file is
693 lib/silcutil/silcutil.c.
695 * Cancel and free any active protocol in the function
696 silc_server_close_connection. Affected file silcd/server.c.
698 * Cancel and free any active protocol in the function
699 silc_client_close_connction. Affected file is
700 lib/silcclient/client.c.
702 * Do not execute the KILL command for clients that are in
703 history (ie. they are not in the network). Affected file is
706 * Fixed KILL notify handling, client does not crash anymore.
707 Affected file irssi/src/silc/core/silc-channels.c.
709 * Reduced the default packet buffer size from 2048 to 1024 in
710 lib/silccore/silcpacket.c.
712 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
713 counter to the SKE context that is incresed when the SKE library
714 performs async operation outside the library. If the outside
715 process frees the SKE context and FREED status will be set
716 and the library will detect after the sync operation that the
717 libary is freed. The affected files are
718 lib/silcske/silcske[_status].[ch].
720 * Resolve the client entry information in the function
721 silc_client_channel_message to assure that NULL pointer is not
722 passed as client entry to the application. */
724 * Fixed the task timeout calculation to assure that there is
725 never negative timeouts. The affected file is
726 lib/silcutil/silcschedule.c.
728 * Fixed the channel user mode notification sending in server.
729 It was sent point-to-point to the router (or to server by router)
730 but it needs to be destined to a channel. The routines now
731 supports sending the channel user mode notifys to the channels
732 when announcing clients and channels. Affected files are
733 silcd/server.c and silcd/packet_receive.c.
735 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
736 It did not actually replace the old channel entry in the cache.
737 Affected file lib/silcclient/client_notify.c.
739 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * Fixed a possible crash in silc_packet_send_prepare. It now
742 assures always that there is enough space in the buffer and
743 at the tail area of the buffer (for MAC).
745 Fixed the inbound buffer reallocation in silc_packet_read.
746 It was old code and did not handle the reallocation correctly.
749 The affected file is lib/silccore/silcpacket.c.
751 * Fixed buffer overflow in silc_parse_nickname in the file
752 lib/silcutil/silcutil.c.
754 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * make install generates new server keys only if there is not
759 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
762 Added check that if the NOREPLY is set then we will not send
763 the away message. This avoids infinite loop of away messages
764 if both clients are away. The affected file is
765 lib/silcclient/client_prvmsg.c.
767 * Fixed client crash if /NICK was given without arguments.
768 Affected file lib/silcclient/command.c.
770 * Server does not send the invite list in INVITE command back
771 to the client if the list was not altered. Added this notion
772 to the protocol spec as well. Affected file silcd/command.c.
774 Fixed possible crash in INVITE command by checking the
775 value of silc_server_get_client_route command.
777 * Fixed the INVITE notify type handling. The arguments are now
778 taken in correct order and client does not crash. The affected
779 file is irssi/src/silc/core/silc-channels.c.
781 Removed the "Inviting xxx to channel" message from the
782 client library away and let the application handle it.
783 Affected file lib/silcclient/command.c. Added that message
784 to Irssi SILC client's message formats.
786 * Fixed CMODE command crash in client. It now checks the
787 amount of arguments correctly and does not crash. The affected
788 file is lib/silcclient/command.c.
790 * Do not create new channel automatically in silc_channels_join
791 but check whether the channel by that name already exists.
792 Affected file irssi/silc/core/silc-channels.c.
794 * Do not send the SERVER_SIGNOFF to router if the disconnected
795 entity was the router. Affected file silcd/server.c.
797 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
798 SILC client as it was missing from there.
800 Added the handling of the KICK notify to the Irssi SILC client
801 as it was missing. Added "you have been kicked" message to
802 Irssi SILC client's message modules formats.
804 Added the handing of the KILL notify to the Irssi SILC client
805 as it was missing. Added the kill message module formats
808 The affected file is irssi/src/silc/core/silc-channels.c.
810 * The router did not save the channel mode the server announced.
811 Affected file silcd/packet_receive.c.
813 * Fixed a possible crash in INFO command in server. If the
814 server did not provide the server info it crashed. Affected
815 file silcd/command.c.
817 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Fixed the GETKEY command in the server to check also the
820 global list. Otherwise the GETKEY would not work correctly
821 in normal SILC server. Affected file silcd/command.c.
823 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Fixed GETKEY crash, it crashed if the command did not succseed.
827 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
830 is now real and not just an macro interface to GMP.
832 Removed the entire GMP from the source tree and imported new
833 NSS MPI library instead. Reason for removing GMP is that it is
834 extremely large and compiles extremely slow. The NSS MPI
835 is only a few files and compiles in less than 10 seconds.
836 The speed is also about the same as GMP. The MPI is imported
839 If the system has GMP installed we will still use the GMP.
840 If it is not then the NSS MPI will be compiled.
842 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Merged a long nickname (127 characters long) crash bugfix from
845 Irssi CVS tree. Affected file irssi/src/core/misc.c.
847 * Merged a freed memory reference bugfix from Irssi CVS tree.
848 Affected file irssi/src/core/commands.c.
850 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Added the server's public key sving and verification to the
853 server when performing the SKE. This was missing and the
854 remote server's (or router's) public key was accepted without
855 checking whether we have it previously or trust it at all.
856 Affected file silcd/protocol.c.
858 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Check in the silc_server_timeout_remote if protocol is active
861 and make sure that the protocol's final callback is called so
862 that all memory if freed. Affected file silcd/server.c.
864 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * silc_server_whois_send_reply crashed the server if the nickname
867 was 127 characters long. Affected file silcd/command.c.
869 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Added sanity check to the silc_server_new_client. If the hostname
872 is provided inside username then check that the provided hostname
873 really is the same as the resolved one. If the hostname was not
874 resolved then check it from the public key. Affected file is
875 silcd/packet_receive.c.
877 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
878 if the server disconnected us and the connection is not valid
879 anymore. Affected file irssi/src/silc/core/silc-channels.c.
881 * Moved the silc_client_[chmode|chumode|chumode_char] away from
882 the library to the lib/silcutil/silcutil.[ch].
884 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Close log file after open. Affected file
887 lib/silcutil/silclog.c.
889 * Check whether sock == NULL in silc_client_send_packet and return
890 if it is. Affected file lib/silcclient/silcclient.c.
892 * Check rec->entry == NULL in the Irssi SILC Client before
893 sending the channel message. Affecte file is
894 irssi/src/silc/core/silc-servers.c.
896 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Merged a splitted window bugfix from Irssi CVS tree. The
899 affected file is irssi/src/fe-text/textbuffer-view.c.
901 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
902 It did not print nickname.
904 * Improved the distributions system a bit.
906 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
909 irssi/src/fe-text/gui-window.c.
911 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
912 to in-active server. The affected file is
913 irssi/src/silc/core/client_ops.c.
915 * Resolve the client in USERS command reply if the entry does
916 not have username resolved. The affected file is
917 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
918 command to WHOIS command to really resolve stuff. The USERS
919 is not used any more in any critical section so WHOIS can
920 be used even though it might be slower than IDENTIFY.
922 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
925 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Changed the protocol API a bit more consistent in the
928 lib/silccore/silcprotocol.[ch].
930 * Changed the following headers to ROBODoc format:
932 lib/silccore/silcpayload.h
933 lib/silccore/silcprotocol.h
934 lib/silccore/silcsockconn.h
936 All core library headers are now formatted.
938 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * Fixed a bug in Irssi SILC client; do not show that you are
941 server/router operator if you really are not. Affected file is
942 irssi/src/silc/core/client_ops.c.
944 * Renamed silc_command_free_payload to silc_command_payload_free.
945 Affected file lib/silccore/silccommand.h
947 * Added silcmath.h to include the prototoypes of various routines
948 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
951 * Changed the following headers to ROBODoc format:
953 lib/silccore/silcchannel.h
954 lib/silccore/silccommand.h
955 lib/silccore/silcid.h
956 lib/silccore/silcidcache.h
957 lib/silccore/silcmode.h
958 lib/silccore/silcnotify.h
959 lib/silccore/silcpacket.h
960 lib/silcmath/silcmath.h
962 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Added checking to the server code not to start the server if
965 ciphers and stuff are not configured properly. Affected files
966 silcd/serverconfig.[h] and silcd/server.c.
968 * Changed the layout of the header files of the public interfaces
969 in the SILC libraries. The new layout supports ROBODoc
970 documentation tool (and some others) so that it is easy to create
971 a library reference manual. All the other headers and source
972 code must still follow the CodingStyle document. Also source
973 code must not include these ROBODoc stuffs, only the headers.
974 Furthermore, all public interface headers must now be named
975 by using `silc' prefix, example: silcapi.h, silccipher.h.
976 Some files were renamed due to this. All the other headers
977 must not be used as public interfaces. I will update the
978 CodingStyle document later. Changed following headers, so far:
980 lib/silcclient/silcapi.h
981 lib/silccore/silcauth.h
982 lib/silccore/silcprivate.h
983 lib/silccrypt/silcdh.h
985 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Removed silc_client_packet_send_flush from the client library
990 as it is not needed. Affected file lib/silcclient/client.[ch].
992 * Added printing of message of unresolved authentication method
993 to the Irssi SILC client. Added it to the module formats.
994 Removed the same message from the client library.
996 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Added new distribution feature, DISTLABEL. Every distribution
999 can define own preprocessor label that can be used in the
1000 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1001 file distributions, acconfig.h.pre and prepare.
1003 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Added Makefile.defines_int to include the actual definitions
1006 for Makefile.defines.in. Tested the new distribution system,
1007 created distributions and tested installation.
1009 * Added AWAY message printing to the Irssi SILC client. Added
1010 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1012 * Added SCONNECT command to call the SILC's CONNECT command.
1013 Cannot use CONNECT directly since Irssi uses that internally.
1014 Affected file irssi/src/silc/core/silc-servers.c.
1016 Added ACTION local command. It is same as ME command but takes
1017 the channel as mandatory argument.
1019 Rewrote some of the Irssi's help files to suite for SILC
1022 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Added Makefile.defines[.in] that should for now on be included
1025 in all Makefile.am file in the source tree. That file includes
1026 all common compilation definitions for SILC source tree.
1028 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1030 * Minor changes to the ./prepare script to change the package
1031 name according the distribution name to the configure.in.
1033 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Created new distribution system. Added file `distributions'
1036 that defines all the distributions that can be created out of
1037 the SILC source tree. The ./prepare script now reads that
1038 file to determine how to prepare the distributions. The
1039 first argument to the ./prepare is the name of the distribution
1040 and second is the version of the distribution. If given
1041 without arguments it creates the default (toolkit) distribution
1042 with the default version (defined in ./prepare).
1044 All Makefile.am files that are subject to the distributions
1045 are now named as Makefile.am.pre. These are ./Makefile.am
1046 and lib/Makefile.am. Others may be changed later.
1048 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Added invite list, ban list, some key management and connection
1051 error message printing to module formats in the Irssi SILC client.
1053 * Added new silc_client_set_away_message to set the away message
1054 that is back to the person who sent private message. The
1055 affected file lib/silcclient/silcapi.h and the
1056 lib/silcclient/client_prvmsg.c.
1058 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Fixed the private message sending in the Irssi SILC client,
1061 added local command KEY to the Irssi SILC client.
1063 Added key management and key agreement message formats to the
1064 irssi/src/fe-common/silc/module-formats.[ch].
1066 Added USERS (alias WHO) printing, server/router operator
1067 indication and LIST command printing to the module formats.
1069 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1071 * Fixed channel joining notify handling, cumode notify handling
1072 from Irssi SILC client.
1074 * Added SILC specific module-formats to the Irssi SILC client so
1075 that SILC specific message hilighting, colors etc is possible.
1076 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1078 Added channel mode, channel user mode, actions, notices,
1079 whois and whowas printing to the the module-formats.c.
1081 * Fixed a bug in channel deletion in the server. The channel
1082 is not left to the cache even if the channel founder auth mode
1083 is set when there are no users anymore on the channel. Affected
1084 file silcd/server.c.
1086 * The silc_net_localhost now resolves the entire hostname including
1087 the domain name. Affected file lib/silcutil/silcnet.c.
1089 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Changed the ask_passphrase client operation to be ascynchronous.
1092 It has now a completion callback and a context that the
1093 application must call after it has got the passphrase from
1094 the user. Affected files lib/silcclient/silcapi.h,
1095 lib/silcclient/protocol.c, lib/silcclient/command.c and
1098 Added SilcAskPassphrase callback that the application calls
1099 to deliver the passphrase to the library.
1101 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1102 The public key verification and especially a certificate
1103 verification is asynchronous procedure.
1105 Added new SILC_SKE_STATUS_PENDING status to indicate the
1106 request is pending and a callback will be called to finalize
1109 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1110 indicate that remote end did not send its public key (or
1111 certificate), even though we require it. Added check for this
1112 condition in the SKE. This was a security bug, now fixed.
1114 Defined new SilcSKEVerifyCbCompletion callback that is called
1115 when the verification process is completed.
1117 The affected files lib/silcske/silcske_status.h and
1118 lib/silcske/silcske.[ch].
1120 * Changed the verify_public_key client operation to be async
1121 as well. Defined SilcVerifyPublicKey callback that is used to
1122 indicate the success of the public key verification process.
1124 Changed the server and client to use the new async client
1127 * Changed the Irssi SILC client's internal scheduler to be called
1128 twice as many times as it used to be. As a result the client
1129 should be a bit faster now. Affected file is
1130 irssi/src/silc/core/silc-core.c.
1132 * Added support to Irssi SILC client of asynchronous public key
1133 verification and passphrase inquiry. Affected file is
1134 irssi/src/silc/core/silc-core.c.
1136 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * Do not say "You have left channel %s" in client library.
1139 Moved it to the application. Affected files are
1140 lib/silcclient/command.c and silc/client_ops.c.
1142 * Fixed silc_client_get_clients. Command context was not
1143 duplicated and was freed memory in the callback. Affected
1144 file lib/silcclient/idlist.c.
1146 * Do not say "you are now talking..." on JOIN command in the
1147 client library. The appliation must handle it.
1149 * Do not say ".. changed topic to" in command reply in the
1150 client libary. The application must handle it.
1152 * Fixed TOPIC command sending in the client library.
1154 * Fixed a memory leak in silc_client_command_free in the file
1155 lib/silcclient/command.c.
1157 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Imported a modified version of Irssi client to the source tree.
1160 The Irssi will be used to create a new client called
1161 Irssi SILC. Imported to irssi/.
1163 Added silc_core_init_finish function to the Irssi. Affected
1164 file irssi/configure.in.
1166 A lot changes in the Makefile.ams around the irssi tree.
1168 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Do not rehash if the new size is same as the old size of the
1171 hash table, in the silc_hash_table_rehash*. The affected file
1172 lib/silcutil/silchashtable.c.
1174 * Replaced hash_table_del_by_context calls from the server
1175 (when channel->user_list and client->channels) to the
1176 hash_table_del as it is sufficient and faster.
1178 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1180 * Added silc_hash_table_list, silc_hash_table_get and the
1181 SilcHashTableList structure to provide an alternative way to
1182 traverse the hash table. The affected files are
1183 lib/silcutil/silchashtable.[ch].
1185 * Changed the server's idlist routines to use the hash table
1186 routines to optimize the code.
1188 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Replaced the client entry's `channel' list and channel entry's
1191 `user_list' list to hash tables for optimized lookup. Changed
1192 the code to use the hash table interface around the code.
1193 Affected file lib/silcd/idlist.[ch].
1195 * Added `auto_rehash' boolean argument to the function
1196 silc_hash_table_alloc to indicate whether the hash table should
1197 auto-rehash when it thinks is appropriate time. It will
1198 increase the hash table size if the there is twice as much
1199 entries in the table than the size of the table, and will
1200 decrease the size if there are twice as less entries than
1201 the size of the table.
1203 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1207 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * silc_idcache_purge_by_context deletes the entry now by context
1210 as it is supposed to do. Affected file lib/silccore/idcache.c.
1212 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1213 client is not anymore valid (WHOWAS givens the info) and not
1214 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1216 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Removed the `data' and `data_len' arguments from the ID Cache
1219 interfaces and added `name' argument. ID Cache does not handle
1220 anymore the binary data only a names associated with given ID.
1222 * When hashing a Client ID with silc_hash_id the entire ID is
1223 not hashed anymore, instead only the hash of the Client ID is
1224 hashed. This way we can access the Client ID from the cache
1225 with Client ID but with the hash of the ID (which is a hash of
1226 the nickname) as well without any difference in performance.
1228 Added also silc_idcache_find_by_id_one_ext to do one on one
1229 searching when we have the actual ID. Added also function
1230 silc_hash_client_id_compare. The affected files are
1231 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1233 * When hashing the name associated with a ID it is always done
1234 in lowercase. This way we can access the cache without worrying
1235 about case-sensitivity, even though, for example nicknames are
1238 * Fixed a bug in server with channel message sending. It put
1239 wrong ID type as destination ID. The affected file
1240 silcd/packet_send.c.
1242 * silc_idcache_del_by_context now deletes from all hash tables
1243 by context. Affected file lib/silccore/idcache.c.
1245 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Changed the client library to use the new ID Cache interface.
1248 Changes around the source tree.
1250 * Added silc_hash_table_rehash_ext to rehash with specific
1251 hash function. Affected file lib/silcutil/silchashtable.[ch].
1253 * Added silc_hash_string_compare to compare two strings in the
1254 hash table. Affected file lib/silcutil/silcutil.[ch].
1256 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Added new function silc_idcache_del_by_context into the
1259 lib/silccore/idcache.[ch].
1261 * Changed the server's ID list routines to use the new ID Cache
1262 interface. Changes around the source tree.
1264 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Added silc_hash_table_del[_by_context]_ext functions in to the
1267 lib/silcutil/silchashtable.[ch].
1269 Removed silc_hash_table_find_all* routines and added new
1270 silc_hash_table_find_foreach to replace them.
1272 Added silc_hash_table_replace_ext function as extended
1273 replacing function. Separated the simple hash table interface
1274 from the extended hash table interface in the file
1275 lib/silcutil/silchashtable.h.
1277 * Fixed minor bugs and changed it to use some of the new
1278 hash table functions in lib/silccore/idcache.c
1280 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Added new function silc_hash_table_find_all to return all keys
1283 in the hash table by the specified key. As the hash table is
1284 collision resistant it also makes it possible to have several
1285 duplicate keys in the hash table. This function may be used to
1286 find all of the keys from the hash.
1288 Added user_context arguments to the SilcHashFunction,
1289 SilcHashCompare and SilcHashDestructor to deliver user specified
1292 Added new fuctions silc_hash_table_find[_all]_ext to do
1293 extended lookup with specified hash and compare functions and
1294 specified user contexts.
1296 Added new function silc_hash_table_add_ext to add the key
1297 with specified hash function and user context.
1299 Added new function silc_hash_table_foreach to traverse all
1300 entrys in the hash table. Added SilcHashForeach callback
1303 Added new function silc_hash_table_del_by_context to delete
1304 the entry only if the context associated with the key matches.
1306 Affected files are lib/silcutil/silchashtable.[ch].
1308 * Removed silc_hash_[server/client/channel]_id and added just
1309 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1310 silc_hash_id_compare to compare two ID's using as the hash table
1311 comparison function. Added also silc_hash_data to hash
1312 binary data and silc_hash_data_compare to compare it.
1314 * Removed silc_idlist_find_client_by_hash as it is not needed
1315 anymore. Affected file silcd/idlist.[ch].
1317 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1318 to use internally the SilcHashTable. The new ID Cache is a lot
1319 faster than the old one. Some of the ID Cache interface was also
1320 rewritten and obsolete and stupid functions were removed.
1322 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Added entry_count field to the SilcHashTable to keep the number
1325 of the entries in the table. Implemented the function
1326 silc_hash_table_rehash. Added new function
1327 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1329 Fixed a minor bug in silc_hash_table_free.
1331 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1332 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1333 into the lib/silcutil/silcutil.[ch].
1335 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Implemented a collision resistant hash table into the
1338 lib/silcutil/silchashtable[ch]. See the header and the source
1339 for the SilcHashTable API.
1341 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Merged dotconf version 1.0.2 into lib/dotconf.
1345 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Do not compile anything in lib/silcsim/* if the SIM support
1348 is not enabled. The tree should now compile without problems
1351 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Compiled the SILC under cygwin. Compiled and tested briefly
1354 without problems. More tests needed. The SIMs didn't compile
1357 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1359 * Fixed possible crash in silc_get_username in the
1360 lib/silcutil/silcutil.c.
1362 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Fixed a va_arg in silc/client_ops.c.
1366 * Oops, RC5 routines were named AES and caused some problems
1367 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1369 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Added new SilcIDIP structure into the lib/silccore/id.h and
1372 replaced the old `ip' fields from all SILC ID's to that type.
1373 This is a step towards IPv6 support.
1375 The silc_id_get_len takes now the ID as an extra argument.
1376 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1377 both IPv4 and IPv6 based ID's.
1379 The affected files are lib/silccore/id.[ch] and other files
1380 around the tree using these routines.
1382 * Removed the ID length arguments in server from various
1383 silc_server_send_notify_* routines -> they are not needed
1386 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Fixed memory leak in silc_encode_pem_file in the file
1389 lib/silcutil/silcutil.c.
1391 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1393 * Check minor version as well in the SKE. Affected files are
1394 silcd/protocol.c and lib/silcclient/protocol.c.
1396 * Added --identifier option to the server so that an identifier
1397 can be when creating the public key for the server. Affected
1398 file is silcd/silcd.c.
1400 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1401 lib/silccrypt/silcpkcs.c.
1403 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Register default ciphers and stuff when using -C option with
1406 the server. Affected file sildc/silcd.c.
1408 * Put back the servers public key filename format, it is better
1409 than the new one. For now, the client keys are saved with the
1410 new filename format. The affected file silc/client_ops.c.
1412 * Implemented the Cipher API for the rest of the ciphers that
1413 did not implement it or implemented it the wrong way.
1415 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * Register default ciphers and stuff when using the -S option
1418 in the client. Affected file silc/silc.c. Same also when
1419 creating new key pair with -C option.
1421 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Fixed the silc_verify_public_key client operation function to
1424 save the public keys differently. The fingerprint is now
1425 used as filename and not the hostname. This way also the
1426 client keys are saved uniquely and not with hostnames. The
1427 affected file is silc/client_ops.c.
1429 * Trimmed the silc_hash_fingerprint function to remove extra
1430 whitespaces from the end of the fingerprint. The affected
1431 file is lib/silccrypt/silchash.c.
1435 * Added silc_cipher_register_default function to register all
1436 default ciphers. It can be used when configuration files
1437 does not exist and the application does not want any specific
1438 ciphers in any specific order.
1440 The SilcDList is now used as silc_cipher_list dynamically
1441 allocated cipher list. Removed the static list all together
1442 and now all ciphers must be allocated to the dynamic list.
1443 The silc_cipher_alloc routine was changed to check only the
1446 All silc_cipher_* routines that used to return int returns
1449 The affected files lib/silccrypt/silccrypt.[ch].
1451 * The same thing was done to silc_hash_* as for silc_cipher_*
1452 routines. Affected files lib/silccrypt/silchash.[ch].
1454 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1455 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1456 Added also silc_pkcs_[un]register[_default] functions.
1457 Removed the data_context from the PKCS API.
1459 * Added silc_hmac_register_default function to register default
1460 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1461 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1462 to unregister all hmacs at once.
1464 * Register the default ciphers, hash functions, PKCSs and HMACs
1465 if client's configuration file does not exist. The affected
1468 * The client did not load the hash functions from the SIM
1469 modules at all. Added support for this. Affected file is
1470 silc/clientconfig.c.
1472 * When decoding public key with silc_pkcs_public_key_decode, check
1473 the supported algorithm only if PKCS are registered. Affected
1474 file lib/silccrypt/silcpkcs.c. The same was done with the
1475 silc_pkcs_private_key_decode.
1477 * Fixed the SILC List routines to keep the list always in order.
1478 It used to change the list's order when traversing the list but
1479 not it preserves the order. Affected file lib/trq/silclist.h.
1481 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * Added the client library to use the SilcSocketConnection's
1484 reference counter (by silc_socket_dup) to prevent the bug that
1485 the socket object may be freed underneath async operation.
1487 * The name resolv library checking fixes in the configure.in.pre.
1490 * Created new version of the protocol drafts for future
1491 development. The -03 drafts are the ones that will be changed
1492 in the trunk now and the -02 will remain as they are.
1494 * Send list of CUMODE notifys to the router when announcing
1495 the channel users to the router. Affected file silcd/server.c.
1496 If the router receiving channel founder CUMODE for a channel
1497 that already has channel founder it will send CUMODE notify
1498 to the sender to remove the channel founder rights from the
1499 announced client. Affected file silcd/packet_receive.c.
1501 * The CUMODE notify may now use Server ID as well as the entity
1502 who changes the mode. Updated protocool specs.
1504 * Updated INSTALL and README files.
1506 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * New web pages in the http://silc.pspt.fi. The pages was
1513 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1515 * Implemented the [DenyConnectin] config section in the server.
1516 Added silc_server_config_denied_conn to check whether incoming
1517 connection is denied. Affected file silcd/serverconfig.[ch].
1519 * Do not check the ports when checking the incoming configuration
1520 data if the port is 0, meaning any. Affected file is
1521 silcd/serverconfig.c.
1523 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Fixed buffer overflow in silc_string_compare in the file
1526 lib/silcutil/silcutil.c.
1528 * Fixed double free in silc_server_command_leave in the file
1531 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Fixed the version checking in the server. Affected file is
1536 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Fixed the configuration data fetching when accepting new
1539 connections in the server. Affected file silcd/server.c.
1541 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Added `sender_entry' argument to the function
1544 silc_server_packet_relay_to_channel so that we can check
1545 whether some destination actually belongs to the same route
1546 the sender belongs (ie, we must not resend the packet to the
1547 sender). Affected file silcd/packet_send.[ch].
1549 * Added `servername' field to the SilcClientEntry in the server
1550 to hold the name of the server where client is from. Affected
1551 file is silcd/idlist.h.
1553 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Moved the channel message encrypting in the router betwen
1556 router connections from silc_server_channel_message to the
1557 silc_server_packet_relay_to_channel since we want to check
1558 whether we have anybody channel before encrypting anything.
1559 Affected files silcd/packet_[receive/send].c.
1561 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Fixed the [AdminConnection] server config section to support
1564 multiple entries. Affected file silcd/serverconfig.c.
1566 * Added support into the server to check the validity of the
1567 incoming connection before executing any KE or authentication
1570 * The connection configuration is now saved to the KE and
1571 connection auth protocol contexts and not fetched anymore in
1572 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1574 * The local hosts listenning address and port is also resolved
1575 now when starting the server. We want to have the socket object
1576 to include the real address and port for the listener. Added
1577 new function silc_net_check_local_by_sock into the files
1578 lib/silcutil/silcnet.[ch].
1580 * Fixed a broadcast bug in server -> do not broadcast if we
1583 * Fixed a routing bug. Do not route broadcast packets ever.
1584 Broadcast packets must be processed always and not routed since
1585 they may be destined to some other host than yourself and thus
1586 would get routed without no good reason. Affected file is
1589 * Added function silc_server_config_is_primary_route to check
1590 whether primary router connection has been configured (a router
1591 configuration that we are initiating). If there is not, we
1592 will assume that there is only two routers in the SILC network
1593 and we will use the incoming router connection as our primary
1594 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1596 * Changed the order of the broadcasting. Broadcast _after_ the
1597 packet has been processed not before. Affected file is
1600 * Fixed a [ClientConnection] parsing bug. The port was never
1601 parsed correctly thus resulting to port 0. Affected file
1602 silcd/serverconfig.c.
1604 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1605 argument and did not set the broadcast packet flag. Affected
1606 file silcd/packet_send.c. Fixed same bug in the function
1607 silc_server_send_notify as well.
1609 * If we receive NEW_ID packet for our own ID in the server, ignore
1612 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1616 * Removed the nickname from the Private Message Payload.
1617 Updated the code and the protocol specs.
1619 * Updated protocol specs for submitting to the IETF.
1621 * Tweaked the Random Number Generator a bit. Affected file
1622 lib/silccrypt/silcrng.c. Exported a new function
1623 silc_rng_[global]_add_noise which can be used to add more
1626 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Do not parse packets with different timeout when protocol
1629 is active -> may cause problem with rekey. Affected file
1632 * When server receives signoff notify it must not create
1633 new channel key if the client is on any channels since the
1634 sender of the signoff notify will create it.
1636 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Added printing of error messages during SKE protocol from the
1639 failure packet sent by server during SKE. Affected file
1642 * Removed the client's failure_callback handling with timeout
1643 and handle it immediately when received.
1645 * The SKE library returned wrong type in SUCCESS and FAILURE
1646 packets. They must be 32 bit MSB not 16 bit MSB.
1648 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Ok, rewrote the logic of the re-key and now it seems to work.
1651 I tested it on high traffic with frequent re-keys without
1652 problems. Added hmac_receive (and renamed hmac to hmac_send)
1653 in SilcClientConnection in lib/silcclient/client.h and
1654 in SilcIDListData in silcd/idlist.h. Also, removed the
1655 SilcPacketParserContext's cipher and hmac fields as they are
1656 not needed anymore and actually caused some problems when
1657 the ciphers and hmac's changed underneath the packet parser.
1659 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * If re-key protocol is active then process the incoming packets
1662 synchronously since we must assure that icoming packets encrypted
1663 with the old key is processed before the new keys is set to
1664 use. This is true other packets than for REKEY packets.
1665 Affected file silcd/server.c. The same was done to client library
1666 as well, affected file lib/silcclient/client.c.
1668 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Fixed bug in client and server to accept the force send if
1671 the packet is send from silc_[server/client]_packet_process
1672 function. Otherwise the packets are never delivered, oops.
1674 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Disable force sending of packets when REKEY protocol is active.
1677 We must assure that no packet is sent directly when rekey is
1678 performed. All packets must be sent through packet queue.
1679 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1680 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1681 function is silc_[server/client]_packet_send_real to check
1684 * Replaced the SIM paths from example config files to
1685 /usr/local/modules. Also, make install creates now
1686 /usr/local/silc/logs directory to hold all the SILC server
1689 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Made the configure.in.pre work on Solaris. Patch by salo.
1693 * Made all ciphers compatible with non-x86 machines. Defined
1694 CBC mode macros into lib/silccrypt/ciphers_def.h.
1696 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * Fixed the make install.
1700 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * When MAC computation fails the silc_packet_decrypt returned 0
1703 even though it was supposed to return -1. Fixed this. The
1704 affected file is lib/silccore/silcpacket.c.
1706 * Do not replace the config files in /etc/silc (in make install)
1707 if they already exist. Affected file ./Makefile.am.
1709 * Do not send re-key packets immediately but through packet queue.
1710 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1712 * Changed silc_net_check_host_by_sock to return FALSE if the
1713 IP/DNS could not be resolved. Though, it returns the IP address
1714 now even if it could not resolve it (but returns also FALSE).
1715 Affected file lib/silcutil/silcnet.[ch].
1717 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Added silc_pkcs_decode_identifier to decode the public key's
1720 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1721 Added also silc_pkcs_free_identifier. Added also new context
1722 SilcPublicKeyIdentifier.
1724 * Added -S option to the silc client. It is used to dump the
1725 contents of the specified public key file.
1727 * Changed the PKCS api to return the public key length when
1728 setting the public key.
1730 * Fixed a fatal bug in the public and private key file loading.
1731 Affected file lib/silccrypt/silcpkcs.c.
1733 * Execute the packet parsing for client with zero (0) timeout
1734 if the protocol is active. Affected file silcd/server.c.
1736 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1738 * Made the key generation options to the silcd program. Added
1739 -C option, equivalent to client's option.
1741 * Added new [ServerKeys] config section to the server. It
1742 configures the server's public and private key.
1744 * Defined generic Public Key Payload into the protocol
1745 specification to send specific type of public keys and
1748 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1749 public key or certificate.
1751 * Implemented the GETKEY command to the server and to the
1752 client library and on user interface.
1754 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1756 * Made preliminary `make install' work.
1758 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Added SilcServerRekey context into silcd/idlist.h.
1762 * Added the PFS support as defined in the specification to the
1763 SKE protocol. Affected files lib/silcske/*.c.
1765 * Added `ske_group' field to the SilcServerRekey context to hold
1766 the number of the SKE group that is used with PFS in re-key.
1767 Affected file silcd/idlist.h.
1769 * Added PFS re-key support to the server. Affected file is
1772 * Added silc_protocol_cancel to cancel execution of the next
1773 state of the protocol. Affected file is
1774 lib/silccore/silcprotocol.[ch].
1776 * Added the re-key support with and without PFS to the client
1777 library. Re-key is performed once in an hour, by default.
1779 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1780 Added silc_client_rekey_callback and silc_client_rekey_final.
1781 Affected files are lib/silcclient/protocol.[ch] and
1782 lib/silcclient/client.[ch].
1784 * Removed the `hmac_key' and `hmac_key_len' fields from the
1785 SilcClientConnection structure; not needed. Affected file is
1786 lib/silcclient/client.h.
1790 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Do not ask whether user wants to use the negotiated private key
1793 for private messages, just use it. Affected file is
1794 silc/local_command.c.
1796 * Added `send_enc_key' and `enc_key_len' fields to the
1797 SilcIDListData structure since they are needed in the re-key
1798 phase. Affected file is silcd/idlist.[ch].
1800 * Implemented the simple re-key protocol into the server.
1801 Affected files silcd/server.c and silcd/protocol.[ch]. The
1802 re-key will be performed once in an hour, by default.
1804 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1805 Added silc_server_rekey, silc_server_rekey_callback and
1806 silc_server_rekey_final.
1808 * Removed Tunneled flag from the protocol. Updated the code
1809 and the specifications.
1811 * Adde `pfs' field to the SilcIDListData to indicate whether
1812 the PFS is to be performed in the re-key. Affected file is
1815 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1818 int64 of at least the xintXX size. If void * is less that 4
1819 bytes uint32 * will be used. Defined bool as boolean.
1821 * Changed _ALL_ unsigned long and unsigned int to uint32,
1822 unsgined short to uint16 in the source tree.
1824 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1825 not handle clients that has entry->data.registered == FALSE.
1826 They are not in the network anymore. Affected file is
1829 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Implemented the sending of the SERVER_SIGNOFF notify in the
1832 server. Affected file is silcd/server.c.
1834 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1835 Added also silc_notify_payload_encode_args into the
1836 lib/silccore/silcnotify.[ch].
1838 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1839 Affected file silcd/packet_receive.c.
1841 * Implemented the SERVER_SIGNOFF notify handling in the client
1842 library. Affected file lib/silcclient/client_notify.c. Also,
1843 implemnted the printing of the SERVER_SIGNOFF info to the
1844 application. Affected file silc/client_ops.c.
1846 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1847 if the deleting was successful. Affected file silcd/idlist.[ch].
1849 * Added support for public key authentication in the connection
1850 authentication protocol in the client library. Affected file
1851 lib/silcclient/protocol.c.
1853 * Changed the server's silc_idlist_get_clients_by_* interface
1854 to support already allocated array so that new entries may be
1855 added to pre-allocated array. Affected file silcd/idlist.[ch].
1856 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1857 and command replies.
1859 * All command reply functions in the server now calls the
1860 pending command callback even if error occured. This way the
1861 error will be delivered to the client as well. Affected files
1862 silcd/command.c and silcd/command_reply.c.
1864 * Fixed INFO command to return local server's info if no server
1865 was provided. Affected file lib/silcclient/command.c.
1867 * Removed RESTART command for good. Updated the code and the
1870 * Rewrote parts of the task system. It is a bit simpler now.
1871 Removed unsued task priorities. The affected files are
1872 lib/silcutil/silctask.[ch].
1874 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Moved the USERS printing from the library to the application.
1877 Affected files lib/silcclient/command.c and silc/client_ops.c.
1879 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Added channel key re-key support. The re-key is perfomed
1884 only by the router and is done once in an hour. Added `rekey'
1885 field to the SilcChannelEntry in the server. Affected files
1886 silcd/server.c and silcd/idlist.h.
1888 * Added silc_task_unregister_by_context into the file
1889 lib/silcutil/silctask.[ch].
1891 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Added SILC_UMODE_GONE mode to indicate when the client is not
1894 present in the SILC network. Added also support to the local
1895 command AWAY that will set this mode. Added support of showing
1896 "xxx is gone" in WHOIS command. The USERS command shows the
1897 gone status as well.
1899 * Fixed setting server and router operator privileges in the
1900 server's UMODE command. Affected file silcd/command.c.
1902 * Merged the SKE KE1 and KE2 payloads into one payload. The
1903 new KE payload is equivalent to the old KE2 payload.
1905 Cleaned up the SKE Start Payload parsing. It now uses the
1906 simple buffer unformatting to do the parsing. A lot faster
1909 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1910 to the SKE that is used to indicate whether both of the SKE
1911 parties should perform authentication. By default only the
1912 responder performs authentication. By setting this flag also
1913 the initiator must do authentication. By default it is unset
1914 since in normal SKE case, client to server connection, only
1915 the responder should do authentication. When doing SKE between
1916 two clients both should perform authentication. Updated the
1917 code and the protocol specs.
1919 * A little fix to IDENTIFY command in the server. Search the
1920 client first by hash not nickname. Affected file is
1923 * Fixed the silc_client_close_connection to support closing
1924 the client to client connections wihtout deleting too much
1925 data. Affected file lib/silcclient/client.c.
1927 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1928 are received if protocol used to be active but is not anymore
1929 the application would crash due to NULL pointer dereference.
1930 Affected files silcd/server.c and lib/silcclient/client.c.
1932 * Added `hash' field to the SilcClientConnection to include
1933 the hash function negotiated in the SKE protocol.
1935 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1936 to set the channel founder authentication data. A client can
1937 claim the founder rights later by providing the authentication
1938 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1939 This way the channel founder can regain the channel founder
1940 privileges even it is left the channel. This works only on
1941 local server and the client must be connected to the same
1942 server to be able to regain the founder rights. Updated the
1943 protocol specs accordingly.
1945 Added support to the CMODE command in the client to set the
1946 founder auth data. Read the README to see how to set it.
1948 Added support to the CUMODE command to claim the founder
1949 rights. Read the README to see how to do it.
1951 Added support for the founder authentication to the Channel
1952 Entry in the server. Affected file silcd/idlist.h.
1954 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1955 server's CMODE command. Affected file silcd/command.c.
1957 * Added the following new functions into lib/silccore/silcauth.[ch]:
1958 silc_auth_get_method and silc_auth_get_data.
1960 * The server now saves the remote hosts public key to the
1961 SilcIDListData pointer. Affected file silcd/protocol.c.
1963 * The normal server now does not remove the channel entry from
1964 the cache if the founder authentication data is set. It used
1965 to remove it if the founder was the last one on the channel on
1966 the server and left the channel. The auth data is saved and
1967 if the channel is re-joined later the old entry is used with
1968 the old auth data. Affected files silcd/command_reply.c and
1971 * Removed the `pkcs' field from the SilcIDListData structure
1972 in the server; it is not used. Affected file silcd/idlist.h.
1974 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Fixed packet processing on slow links. Partial packets were
1977 never re-processed because the incoming data buffer was cleared
1978 by the application. Application must not directly clear the
1979 sock->inbuf, the packet processing routines handle it. Fixed
1980 this in client library and in server.
1982 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Fixed the WHOIS and IDENTIFY send reply function to really
1985 check whether to send list or just one entry. Affected file
1988 * Cleaned up the LEAVE command's channel key distribution. The
1989 affected file silcd/command.c.
1991 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1992 can enforce the channel mode as well. In that case the ID
1993 includes the ID of the server. The code now enforces the
1994 mode change if the router have different mode than the server.
1996 * The notify client operation with CMODE_CHANGE notify can now
1997 return NULL client_entry pointer if the CMODE was not changed
1998 by client. Application must check for this.
2000 * Added <Server ID> argument to INFO command to support server
2001 info fetching by Server ID.
2003 * Added silc_server_announce_get_channel_users to get assembled
2004 packets of channel users of the specified channel. Affected
2005 file silcd/server.[ch].
2007 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2008 was freed underneath the ID Cache.
2010 * Re-announce clients when the server received CHANNEL_CHANGE
2011 notify from the router. Affected file silcd/packet_send.c.
2013 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2016 crashed since it did not handle the fact that there is no cipher
2017 called "3" and didn't check the error condition. Now fixed.
2019 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2020 flag. It can be used to send message requests.
2022 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Implemented the RESTART command in the client.
2026 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2027 notice type messages. Added notice printing to the user
2030 * The channel keys are not re-generated if the channel's mode
2031 is PRIVKEY, ie private key on the channel exists. Affected
2032 files silcd/server.c and silcd/command.c.
2034 * Fixed a little bug in channel message delivery when channel
2035 private keys are set in the server. Affected file is
2036 silcd/packet_send.c.
2038 * Changed the setting on channel->on_channel = TRUE from the
2039 silc_client_save_channel_key to the JOIN command reply. The
2040 key payload is not received if the private channel key is set.
2041 Affected file lib/silcclient/command_reply.c and the
2042 lib/silcclient/client_channel.c.
2044 * When the CMODE_CHANGE notify is sent and the channel private
2045 key mode is removed the channel key must be re-generated in
2046 other cells as well. Added this support for the router in the
2047 silcd/packet_receive.c.
2049 * Added new local command NOTICE to send notice message on
2050 channel. Affected file silc/local_command.[ch].
2052 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Added new local command ME to the client. It is used to send
2055 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2056 some action. Affected file silc/local_command.[ch].
2058 * Changed channel_message and private_message client operations
2059 to deliver the message flags to the application. Added also
2060 the `flags' arguments to the silc_client_send_channel_message
2061 and silc_client_send_private_message functions. Affected file
2064 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Redefined the Private Message Payload to support private message
2067 keys and to support the new private message flags. Updated
2068 the protocol specs. Flags makes it possible to have for example
2069 CTCP style messages.
2071 * Added new type SilcPrivateMessagePayload and defined an API
2072 for it in the lib/silcclient/silcprivate.[ch].
2074 * Tested private message private keys successfully. Tested the
2075 private message key set, unset and list commands with the new
2078 * Redefined the Channel Message Payload to include the channel
2079 message flags (equal with private message flags) to support
2080 for example CTCP style messages.
2082 * Defined some of the message (for channel and private message)
2083 flags. Updated the protocol specs and added the flags to the
2084 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2086 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Added SilcKeyAgreementStatus type to the key agreement routines
2089 to indicate the current status and error if one occured.
2090 The status types are defined in the lib/silcclient/silcapi.h.
2092 * Added new local command KEY that is used to set and unset private
2093 keys for channels, set and unset private keys for private messages
2094 with remote clients and to send key agreement requests and
2095 negotiate the key agreement protocol with remote client. The
2096 key agreement is supported only to negotiate private message keys,
2097 it currently cannot be used to negotiate private keys for channels,
2098 as it is not convenient for that purpose.
2100 * Fixed a minor pending callback setting bug in the function
2101 silc_client_get_client_by_id_resolve, now the function works.
2102 Affected file lib/silcclient/idlist.c.
2104 * Added function silc_net_get_local_port to get local bound
2105 port by socket. Added to lib/silcutil/silcnet.[ch].
2107 * Added `sockets' and `sockets_count' fields to the SilcClient
2108 object. They hold the sockets of the listenning sockets in
2109 the client. Listenning sockets may be for example the key
2110 agreement server. Affected file lib/silcclient/client.[ch].
2111 Added functions the silc_client_add_socket and the
2112 silc_client_del_socket. They are exported to the application
2115 * Added ~./silc/clientkeys to support other client's public keys.
2117 * Renamed verify_server_key client operation to verify_public_key
2118 and added one argument to indicate the type of the connection
2119 (server, client etc.).
2121 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Added silc_server_connection_auth_request to handle the
2124 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2125 silcd/packet_receive.[ch].
2127 * Added silc_server_send_connection_auth_request into the
2128 silcd/packet_send.c to send the connection auth request packet.
2130 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2133 * Fixed the public key authentication in responder side in the
2134 server. The `auth_data' pointer includes the SilcPublicKey
2135 not the path to the public key. Affected file silcd/protocol.c.
2137 * Implemented the public key authentication in the initiator side
2138 in the server. Affected file silcd/protocol.c.
2140 * Removed the [RedirectClient] config section from the server
2141 configuration. Is not needed and I don't want to implement it.
2143 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Cleaned up the CMODE command in the server. It now works
2146 correctly and supports all the modes defined in the protocol.
2147 Affected file is silcd/command.c.
2149 * Added `hmac_name' field to the SilcChannelEntry in the server
2150 to hold the default HMAC of the channel. It can be set when
2151 creating the channel (with JOIN command). Affected files
2154 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2155 type to indicate the change of the current cipher and hmac
2156 on the channel. Client can safely ignore the <cipher> argument
2157 (if it chooses to do so) since the CHANNEL_KEY packet will
2158 force the channel key change anyway. The <hmac> argument is
2159 important since the client is responsible of setting the new
2160 HMAC and the hmac key into use.
2162 * Fixed the CMODE command in the client library as well.
2164 * Tested CMODE command in router environment successfully.
2166 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Show the version of the remote client (or server) when connecting
2169 to the server. It is logged to the log file. Affected file
2170 is silcd/protocol.c.
2172 * Fixed the KILLED notify handling in the client library. The
2173 client must be removed from all channels when receiving the
2176 Also, do not remove the client entry when giving the KILL
2177 command but when the KILLED notify is received.
2179 * Removed silc_idlist_find_client_by_nickname from the server.
2180 Not needed anymore. Affected files silcd/idlist.[ch].
2182 * Implemented the CHANNEL_CHANGE notify type handling to the
2183 server. Affected file silcd/server.c.
2187 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2190 notify between routers.
2192 * Implemented the INVITE command correctly to the server.
2194 * Implemented the INVITE notify type handling in the server.
2196 * Implemented the INVITE command to the client library and on the
2199 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Added function silc_server_get_client_resolve to find the
2202 client entry by ID from all ID lists and then resolve it
2203 (using WHOIS) if it cannot be found. Affected file is
2206 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Implemented the BAN command to the client library.
2210 * The JOIN command in the server now checks the invite list
2213 * Changed the silc_command_reply_payload_encode_va and the
2214 silc_command_payload_encode_va to support that if argument is
2215 NULL it ignores and checks the next argument. Affected file
2216 lib/silccore/silccommand.c.
2218 * Added silc_server_send_notify_ban to send the BAN notify
2219 type between routers.
2221 * Chaned the silc_notify_payload_encode to support that if
2222 argument is NULL it ignores and checks the next argument.
2223 Affected file lib/silccore/silcnotify.c.
2225 * Tested ban lists in router environment successfully.
2227 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Implemented BAN command to the server, in silcd/command.[ch].
2231 * Removed the BAN and INVITE_LIST modes from the CMODE command
2234 * Added function silc_string_match to regex match two strings.
2235 Affected files lib/silcutil/silcutil.[ch].
2237 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Redefined parts of the SilcChannelEntry in the server to support
2240 the new ban and invite lists.
2242 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Redefined the INVITE command. The same command can be used to
2245 invite individuals to the channel but also to manage the invite
2246 list of the channel (to add to and remove from the invite list).
2247 Updated the protocol specs.
2249 * Added new command SILC_COMMAND_BAN that can be used to manage
2250 the ban list of the channel. Updated the protocol specs.
2252 * Removed the channel modes: the SILC_CMODE_BAN and the
2253 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2254 in the CMODE command. The equivalent features are now available
2255 using INVITE and BAN commands. Updated the protocol specs.
2257 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2258 in the network about change in the current ban list. The notify
2259 type is not used by the client.
2261 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2262 support the invite lists.
2264 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Added new function silc_string_regexify that converts string
2267 including wildcard characters into regex string that can
2268 be used by the GNU regex library. Added into the file
2269 lib/silcutil/silcutil.[ch].
2271 Added silc_string_regex_combine to combine to regex strings
2272 into one so that they can be used as one regex string by
2273 the GNU regex library. Added into the file
2274 lib/silcutil/silcutil.[ch].
2276 Added silc_string_regex_match to match two strings. It returns
2277 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2279 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Imported GNU regex to the soruce tree into lib/contrib.
2282 Fixed some compiler warning from the regex.c.
2284 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Fixed MOTD command in the server to work in router environment.
2288 * Fixed the MOTD command in the client library to support
2289 the server argument in the command.
2291 * Added `nickname_len' argument to the silc_idlist_add_client
2292 in the server, as the `nickname' argument may be binary data
2295 * Added silc_idlist_get_channels to return all channels from
2298 * Implemented LIST command to the server. Affected file is
2301 * Implemented the LIST command to the client library and on the
2304 * Added [<user count>] argument to the LIST command reply.
2305 With private channels the user count is not shown.
2307 * Updated TODO and README.
2309 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * The client entry's data.registered must be TRUE even with
2312 global client entry on global client list. The data.registered
2313 is used to check whether the client is anymore in the network,
2314 for example with WHOWAS command so it must be valid.
2316 * Fixed the WHOWAS command in the server. It now actually works
2317 in router environment. Added function into silcd/command_reply.c
2318 silc_server_command_reply_whowas_save.
2320 * Added silc_idlist_purge function to the silcd/idlist.c
2321 to periodically purge the ID Cache.
2323 * Fixed INFO command in the server. It works now in router
2324 environment. Added <server name> argument to the INFO command
2325 reply. Updated the protocol specs.
2327 * Fixed minor bug in silc_idcache_purge to not purge if the
2328 expire value is zero.
2330 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2331 they were buggy because of the WHOWAS information.
2333 * Fixed local command MSG to handle the async resolving of
2334 the remote client properly. It used to fail the first MSG.
2335 Affected file silc/local_command.c.
2337 * Added `data_len' field to SilcIDCache context.
2339 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Update TODO. Todo in commands in the server.
2343 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2346 used by routers as broadcast packet to inform other routers
2347 about the changed user mode.
2349 Implemented the notify handling in the server. Affected file is
2350 silcd/packet_receive.c. Added the function
2351 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2353 * Added new generic Channel Payload and deprecated the New Channel
2354 Payload. The New Channel Payload is now the generic Channel
2357 * Added new argument `mode' to the silc_server_send_new_channel
2358 as it is required in the Channel Payload now.
2360 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2361 and created a new and real SilChannelPayload to represent the
2362 new generic Channel Payload. Implemented the encode/decode
2363 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2365 * Added silc_server_get_client_channel_list to return the list
2366 of channels the client has joined for WHOIS command reply.
2367 Affected file silcd/server.[ch].
2369 * Implemented the channel list sending in the WHOIS command reply
2370 in server and in the client.
2372 Implemented the channel list displaying on the user interface
2373 as well. Affected file silc/client_ops.c.
2375 * Added silc_channel_payload_parse_list to parse list of Channel
2376 Payloads. It returns SilcDList list of SilcChannelPayloads.
2377 Client for example can use this function to parse the list of
2378 channels it receives in the WHOIS command reply. The caller
2379 must free the list by calling silc_channel_payload_list_free.
2380 Affected files lib/silccore/silcchannel.[ch].
2382 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Added one new argument <user mode> to the WHOIS command reply
2385 to return the mode of the user in SILC. Updated the protocol
2388 Implemented it to the server and client.
2390 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Fixed the mode printing on the user interface on joining.
2393 Affected file silc/client_ops.c.
2395 * Implemented the UMODE command and user modes in general to the
2396 client library and to the user interface.
2398 * Implemented the UMODE command to the server.
2400 * The server now sends UNKNOWN_COMMAND error status if client sends
2401 unknown command. Affected file silcd/command.c.
2403 * All server commands now handle the command identifier the right
2404 way when sending the command reply to the client. The client can
2405 use to identify the command replies with the identifier.
2407 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Added silc_server_get_client_route to resolve the route to
2410 the client indicated by the client ID. Affected file is
2413 * Added silc_server_relay_packet as general function to relay
2414 packet to arbitrary destination. This deprecates functions
2415 like _send_private_message_key, _relay_notify etc. Affected
2416 file is silcd/packet_send.[ch].
2418 Removed silc_server_send_key_agreement,
2419 silc_server_send_private_message_key and
2420 silc_server_packet_relay_notify functions from the file
2421 silcd/packet_send.[ch].
2425 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2426 server. Affected file silcd/packet_receive.[ch].
2428 * Implemented the KILL command to the client. Implemented the
2429 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2430 Affected files lib/silcclient/command[_reply].c and
2431 lib/silcclient/client_notify.c. Implemented the KILL notify
2432 printing in the user inteface.
2434 * Fixed a lot silc_parse_nick memory leaks from the client
2435 library in the file lib/silcclient/command.c.
2437 * Changed the silc_server_send_notify_on_channels's `sender'
2438 argument from SilcSocketConnection to SilcClientEntry to
2439 check the sender as entry and not as connection object and not
2440 to send to the client provided as argument. The affected file
2441 is silcd/packet_send.[ch].
2443 * The notify packets that are destined directly to the client used
2444 to not to be processed by the server. Now changed that and the
2445 server processes all notify packets. After relaying the packet
2446 to the client the notify packet is processed in the server.
2448 * The silc_server_free_client_data now checks whether there is
2449 pending outgoing traffic for the client and purges the data to
2450 the network before removing the client entry.
2452 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2455 an client is killed from the SILC Network. Updated the protocol
2458 Added new function silc_server_send_notify_killed to the
2459 silcd/packet_send.[ch].
2461 * Added function silc_server_packet_relay_notify to relay notify
2462 packets that are destined directly to a client. In this case
2463 the server does not process the notify packets but merely relays
2464 it to the client. Affected file silcd/packet_send.[ch].
2466 Added also silc_server_packet_process_relay_notify to check
2467 whereto relay the notify. Affected file is
2468 silcd/packet_receive.[ch].
2470 * Implemented the KILL command to the server.
2474 * Added the backup schema desgined last fall to the protocol
2475 specs for everyone to see. The specification is in the
2476 *-spec-xx.txt draft and the packet type definitions for the
2477 backup routers is in *-pp-xx.txt draft. Thusly, added also
2478 new packet type SILC_PACKET_CELL_ROUTERS.
2480 * A big security problem in the implementation discovered. The
2481 signoff of an client did not cause new channel key generation
2482 which it of course should've done. The channel keys must be
2483 always re-generated when client leaves (or signoffs) the channel.
2484 The silc_server_remove_from_channels funtion now handles
2485 the channel key re-generation.
2487 * Added `sender' argument to the silc_server_send_notify_on_channels
2488 to not to send the client provided as argument. Affected file
2489 silcd/packet_send.[ch].
2491 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Implemented OPER and SILCOPER commands into the server and
2496 * Added silc_auth_verify and silc_auth_verify_data to verify
2497 the authentication directly from the authentication payload.
2498 It supports verifying both passphrase and public key based
2499 authentication. Affected file lib/silccore/silcauth.[ch].
2501 * Added `hash' field to the SilcIDListData structure. It is the
2502 hash negotiated in the SKE protocol. Affected file is
2505 * Slight redesigning of the SilcAuthPayload handling routines.
2506 Do not send SilcPKCS but SilcPublicKey as argument.
2508 * Implemented the public key authentication support to the
2509 serverconfig. The public key is loaded from the provided path
2510 and saved as authentication data to void * pointer. Thus,
2511 changed the unsigned char *auth_data to void *auth_data;
2513 * Fixed SHUTDOWN command to send the reply before the server
2514 is shutdown. :) Affected file silcd/command.c.
2516 * Fixed fatal bug in CONNECT command. The hostname was invalid
2517 memory and server crashed. Affected file silcd/command.c.
2519 * Fixed fatal bug in CLOSE command. The server_entry became
2520 invalid but was referenced later in the command. Affected file
2523 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Fixed fatal bug in failure packet handling. Server ignored
2526 the failure and thus crashed when it came.
2530 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2533 that the command may be executed only once in (about) 2 seconds.
2534 The old SILC_CF_LAG flag is same but allows command bursts up
2535 to five before limiting.
2537 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2538 server code. Various commands now includes the CF_LAG_STRICT
2539 flag to disallow any kind of miss-use of the command.
2541 * Fixed the silc_buffer_unformat to not to allocate any data
2542 if the length of the data is zero. It used to allocate the
2543 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2545 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2547 * Changed the format of AdminConnection configuration section
2548 in the server. Added username of the admin to the format.
2549 Affected files silcd/serverconfig.[ch].
2551 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2552 to return admin configuration data by host, username and/or
2555 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Implemented WHOWAS command to the server. Added the functions:
2559 silc_server_command_whowas_parse,
2560 silc_server_command_whowas_send_reply,
2561 silc_server_command_whowas_from_client and
2562 silc_server_command_whowas_from_server
2564 * Added <Client ID> argument to the WHOWAS command reply. Updated
2565 the protocol specs accordingly.
2567 * Implemented WHOWAS command and command_reply to the client
2570 Implemented the WHOWAS printing on the user interface.
2572 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Added new argument to the WHOWAS command reply, the real name.
2575 It is an optional argument. Updated the protocol specs.
2577 * Added SilcIDCacheDestructor callback that is registered when
2578 the SilcIDCache is allocated. The callback is called when
2579 an cache entry in the ID Cache expires, or is purged from the
2580 cache. Added into lib/silccore/idcache.[ch].
2582 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2583 to destruct the client entries when the cache entry expires.
2584 Other ID Cache's in server and in the client library ignores
2587 * If the ID Cache entry's `expire' field is zero then the entry
2588 never expires. Added boolean `expire' argument to the
2589 silc_idcache_add function in the lib/silccore/idcache.[ch].
2590 If it is TRUE the default expiry value is used.
2592 * Added silc_server_free_client_data_timeout that is registered
2593 when client disconnects. By default for 5 minutes we preserve
2594 the client entry for history - for WHOWAS command.
2596 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Added support to the server to enforce that commands are not
2599 executed more than once in 2 seconds. If server receives
2600 commands from client more frequently, timeout is registered
2601 to process the commands. Affected file silcd/command.c.
2602 Added new function silc_server_command_process_timeout.
2604 * Changed NICK_NOTIFY handling in client library to check that
2605 if the client's nickname was changed, so there is no need to
2606 resolve anything from the server.
2608 * Removed error printing from the WHOIS and IDENTIFY commands.
2609 If error occurs then it is ignored silently in the client library.
2610 The application, however, may map the received error to
2611 human readable error string. The application currently maps
2612 the NO_SUCH_NICKNAME error to string.
2614 * Made the command status message public to the application. Moved
2615 them from lib/silcclient/command_reply.c to
2616 lib/silcclient/command_reply.h. The application can map the
2617 received command status to the string with the
2618 silc_client_command_status_message function.
2620 * Added check to the server to check that client's ID is same
2621 as the Source ID in the packet the client sent. They must
2624 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Added dist-bzip hook to the Makefile.am to make bzip2
2627 compressed distributions.
2629 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Server now enforces the maximum length for the nickname and
2632 the channel as protocol specification dictates. 128 bytes for
2633 nickname and 256 bytes for channel name.
2635 * Moved the WHOIS printing to the application. The client libary
2636 does not print out the WHOIS information anymore, the application
2637 must do it. Renamed silc_client_command_reply_whois_print to
2638 the silc_client_command_reply_whois_save.
2640 The client's idle time is also sent to the application now, and
2641 the idle is shown on screen.
2643 * Added silc_client_command_reply_identify_save to save the
2644 received IDENTIFY entries.
2646 * Do not check for channel private keys in message sending and
2647 reception if the channel does not have the PRIVKEY mode set.
2648 Affected file lib/silclient/client_channel.c.
2650 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2653 just surfaced after chaning the JOIN procedure.
2655 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Added silc_client_get_clients_by_list to get client entries
2658 from Client ID list, that is returned for example by JOIN
2659 and USERS command replies. The application should use this
2660 function for example when JOIN command reply is received to
2661 resolve the clients already on the channel (library does not
2662 do that anymore as USERS command reply is not used in the JOIN
2663 procedure anymore). Affected files lib/silcclient/silcapi.h and
2664 lib/silcclient/idlist.c.
2666 * JOIN command reply and USERS command reply returns now SilcBuffer
2667 pointers instead of unsigned char pointers when returning
2668 the client list and mode list.
2670 * Added <Client ID> argument to the JOIN command reply, mainly
2671 for the server to identify for which client the command was
2672 originally sent. Updated protocol specs accordingly.
2674 * Added SilcDlist private_key pointer to the SilcChannelEntry
2675 in the client to support the channel private keys. Affected
2676 file is lib/silcclient/idlist.h.
2678 * Added SilcChannelPrivateKey argument to the function
2679 silc_client_send_channel_message so that application can choose
2680 to use specific private ke if it wants to. If it is not provided,
2681 the normal channel key is used, unless private keys are set.
2682 In this case the first (key that was added first) is used
2683 as the encryption key.
2685 * Implemented the support for channel private key handling.
2686 Implemented the following functions:
2688 silc_client_add_channel_private_key,
2689 silc_client_del_channel_private_keys,
2690 silc_client_del_channel_private_key,
2691 silc_client_list_channel_private_keys and
2692 silc_client_free_channel_private_keys
2694 Affected file lib/silcclient/client_channel.c.
2696 * Added the support for the private keys in the channel message
2697 sending and encryption and in the message reception and
2698 decryption. Affected funtions are
2699 silc_client_send_channel_message and silc_client_channel_message.
2701 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Added SKE's key verify callback to the client library's
2704 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2706 * Removed the statement that server (or router) must send USERS
2707 command reply when joining to the channel so that the client
2708 knows who are on the channel. Instead, the client list and
2709 client's mode list is now sent in the JOIN command reply to the
2710 client who joined channel. This is better solution.
2712 * Added function silc_server_get_users_on_channel and function
2713 silc_server_save_users_on_channel to the silcd/server.[ch].
2715 * Removed function silc_server_command_send_users from the
2718 * Do not show topic on the client library anymore. The topic is
2719 sent in the command reply notify to the application and the
2720 application must show the topic now.
2722 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Added client searching by nickname hash into the IDENTIFY and
2725 WHOIS commands in the server as they were clearly missing from
2726 them. Affected file is silcd/command.c.
2728 * Fixed a bug in private message receiving in the client library.
2729 The remote ID was freed and it wasn't supposed, now it is
2732 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Minor fix to the channel payload; allocate the data area, as it
2735 needs to be of specific length.
2737 * If the key agreement port is zero then the operating
2738 system will define the bound port. Affected files are
2739 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2741 * Added new function silc_channel_payload_decrypt into the file
2742 lib/silccore/silcchannel.[ch].
2744 * Moved the channel message etc, check from silc_packet_decrypt
2745 to applications. The library calls now a generic
2746 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2747 when the packet is either normal or special. This was done to
2748 allow more wide range of checking that was not allowed when
2749 the code was in library. Now applications can do virtually any
2750 checks to the packet and return to the library the decision how
2751 the packet should be processed. Affected files are
2752 lib/silccore/silcpacket.[ch].
2754 Added silc_server_packet_decrypt_check to the server and
2755 silc_client_packet_decrypt_check to the client library.
2757 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2758 to send with specified source and destination information.
2760 * Channel message delivery between routers was broken after the
2761 channel key distribution was fixed earlier. The channel key
2762 was used be to distributed to other routers as well which is not
2763 allowed by the protocol. Now this is fixed and channel keys
2764 really are cell specific and the channel message delivery between
2765 routers comply with the protocol specification.
2767 * Fixed various commands in server to check also the global list
2768 for the channel entry and not just the local list. The affected
2769 file silcd/command.c.
2771 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Added assert()s to buffer formatting and unformatting routines
2774 to assert (if --enable-debug) when error occurs. Affected
2775 file: lib/silcutil/silcbuffmt.c.
2777 * Changed to auto-reconnect to check whether the remote host is
2778 router and register the re-connect timeout if it is. It used
2779 to check that whether we are normal server, but router must do
2780 auto-reconnect with another router as well. Affected file
2783 * Removed the [<key len>] option from CMODE command as the cipher
2784 name decides the key length, nowadays. See the defined ciphers
2785 from the protocol specification.
2787 * Added [<hmac>] option to the CMODE command to define the HMAC
2788 for the channel. Added SILC_CMODE_HMAC channel mode.
2790 * Added [<hmac>] option for the JOIN command so that user can
2791 select which HMAC is used to compute the MACs of the channel
2794 * Added Hmac field to the Channel Message Payload. The integrity
2795 of plaintext channel messages are now protected by computing
2796 MAC of the message and attaching the MAC to the payload. The
2797 MAC is encrypted. Now, it is clear that this causes some
2798 overhead to the size of the packet but rationale for this is that
2799 now the receiver can verify whether the channel message decrypted
2800 correctly and also when private keys are set for the channel the
2801 receiver can decrypt the packet with several keys and check from
2802 the MAC which key decrypted the message correctly.
2804 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2805 lib/silccrypt/silccipher.[ch].
2807 * Added silc_hash_len to return the digest length into the
2808 lib/silcrypt/silchash.[ch].
2810 * Rewrote parts of Silc Channel Payload interface in the
2811 lib/silccore/silcchannel.[ch]. The encode function now also
2812 encrypts the packet and parse function decrypts it.
2814 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Fixed a minor formatting bug in the SKE's key material processing.
2817 It actually might have processed the keys wrong way resulting
2820 * Redefined the mandatory HMAC algorithms and added new algorithms.
2821 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2822 and hmac-md5 truncated to 96 bits. The mandatory is now
2823 hmac-sha1-96. Rest are optional (including the one that used
2824 to be mandatory). Rationale for this is that the truncated HMAC
2825 length is sufficient from security point of view and can actually
2826 make the attack against the HMAC harder. Also, the truncated
2827 HMAC causes less overhead to the packets. See the RFC2104 for
2830 * Added new [hmac] configuration section. The SKE used to use
2831 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2832 is of course wrong. The official names that must be proposed in
2833 the SKE are the ones defined in the protocol specification
2834 (hmac-sha1-96 for example). The user can configure any hmac
2835 using any hash function configured in the [hash] section. At
2836 least, the mandatory must be configured.
2838 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2840 * Added HMAC list to the SKE proposal list. It has now both
2841 hash algorithm list and HMAC list. This makes the protocol
2842 incompatible with previous versions. The SKE now seems to work
2843 the way it is supposed to work, for the first time actually.
2845 * Defined plain Hash algorithms to the protocol specification.
2848 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Implemented support for key agreement packets into the server.
2851 Added functions silc_server_key_agreement and
2852 silc_server_send_key_agreement. Other than these functions,
2853 server has nothing to do with this packet.
2855 * Added support for private message key packets into the server.
2856 Added functions silc_server_private_message_key and
2857 silc_server_send_private_message_key.
2861 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2862 called in the protocol's final callback instead in the END
2863 protocol state. This makes a little more sense and in the same
2864 time in client we can use the same protocol routines for normal
2865 key exchange and to key agreement packet handling as well.
2867 * Added to both client's and server's KE protocol context the
2868 SilcSKEKeyMaterial pointer to save the key material. We will
2869 bring the key material to the protocol's final callback by doing
2870 this. The final callback must free the key material.
2872 * Added SKE's packet_send callback into client's KE protocol
2873 context so that the caller can choose what packet sending function
2874 is used. This way we can use different packet sending when
2875 doing normal SKE when doing key agreement packet handling (in
2876 the key agreement packet handling we do not want to encrypt
2879 * Implemented the responder side of the key agreement routines
2880 in the client. The client can now bind to specified port and
2881 accept incoming key negotiation. The key material is passed
2882 to the application after the protocol is over.
2884 * Implemented the processing of incoming Key Agreement packet
2885 in the client. Added function silc_client_key_agreement to
2888 * Implemented the intiator side of the key agreement routines
2889 in the client. The client can now initiate key agreement with
2890 another remote client. The key material is passed to the
2891 application after the protocol is over.
2893 * Created client_keyagr.c to include all the key agreement
2896 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2897 SILC_TASK_CALLBACK except that it is not static.
2899 * Created client_notify.c and moved the Notify packet handling
2900 from the client.[ch] into that file.
2902 * Created client_prvmsg.c and moved all private message and
2903 private message key routines from the client.[ch] into that file.
2905 * Create client_channel.c and moved all channel message and
2906 channel private key routines from the client.[ch] into that file.
2908 * Changed silc_client_get_client_by_id_resolve to resolve with
2909 WHOIS command instead of IDENTIFY command, in the file
2910 lib/silclient/idlist.c.
2912 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Implemented the SKE's responder side to the Client library.
2916 * When FAILURE is received to the protocol do not trust it
2917 blindly. Register a timeout to wait whether the remote closes
2918 the connection as it should do it, only after that process the
2919 actual failure. This was changed to both client and server.
2921 * Added client_internal.h to include some of the structures
2922 there instead of client.h in lib/silcclient/.
2924 * Added function silc_task_unregister_by_callback to unregister
2925 timeouts by the callback function.
2927 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Some "Incomplete WHOIS info" errors has been appearing on the
2930 log files. Took away the entry->userinfo check from WHOIS
2931 reply sending. The entry->userinfo is now " " if client did not
2932 provide one. I thought this was fixed earlier but something
2933 is wrong still. Let's see if the error still appears.
2935 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Fixed a minor bug in the login when the channel key is
2938 re-generated in the server. It used to generate the key in
2939 wrong order and thus caused problems in the channel traffic.
2941 * Fixed a minor bug in channel key distsribution after
2942 KICK command. The key was not sent to the router even though
2945 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Added silc_ske_process_key_material_data as generic routine
2948 to process any key material as the SILC protocol dictates. The
2949 function is used by the actual SKE library but can be used by
2950 applications as well. This relates to the private message keys
2951 and the channel private keys since they must be processed the
2952 same way the normal SILC session keys. The protocol dictates
2953 this. Affected files: lib/silcske/silcske.[ch].
2955 Added also silc_ske_free_key_material to free the
2956 SilcSKEKeyMaterial structure.
2958 * Defined silc_cipher_set_key function to set the key for
2959 cipher without using the object's method function. The affected
2960 files: lib/silccrypt/silccipher.[ch].
2962 * Implemented silc silc_client_add_private_message_key,
2963 silc_client_add_private_message_key_ske,
2964 silc_client_del_private_message_key,
2965 silc_client_list_private_message_keys and
2966 silc_client_free_private_message_keys functions in the
2969 Added functions silc_client_send_private_message_key to send
2970 the Private Message Key payload and silc_client_private_message_key
2971 to handle incoming Private Message Key payload.
2973 * Added Cipher field to the Private Message Key payload to set
2974 the cipher to be used. If ignored, the default cipher defined
2975 in the SILC protocol (aes-256-cbc) is used.
2977 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Removed lib/silcclient/ops.h file.
2981 Redefined parts of the SILC Client Library API. Created new
2982 file silcapi.h that deprecates the ops.h file and defines the
2983 published Client Library API. Defined also private message key
2984 API and channel private key API into the file.
2986 This is the file that the application must include from the
2987 SILC Client Library. Other files need not be included by
2988 the application anymore.
2990 * Added new key_agreement client operation callback and also
2991 defined the Key Agreement library API for the application.
2993 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2996 is used by clients to request key negotiation between another
2997 client in the SILC network. If the negotiation is started it
2998 is performed using the SKE protocol. The result of the
2999 negotiation, the secret key material, can be used for example
3000 as private message key.
3002 Implemented the Key Agreement payload into the files
3003 lib/silccore/silauth.[ch].
3005 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Redefined ciphers for the SILC protocol. Added some new ciphers
3008 and defined the key lengths for the algorithms. Changed the
3009 code accordingly. The default key length is now 256 bits.
3011 * Fixed SKE key distribution function silc_ske_process_key_material
3012 when the key length is more than 128 bits. The default key
3013 length in SILC is now 256 bits.
3015 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3016 to indicate unsupported algorithm.
3018 * Renamed rijndael.c to aes.c and all functions as well.
3020 * Fixed a long standing channel key setting bug in client library.
3021 Weird that it has never surfaced before.
3023 * Fixed bug in channel deletion. If the entire channel is removed
3024 then it must also delete the references of the channel entry
3025 from the client's channel list as the client's channel entry and
3026 the channel's client entry share same memory.
3028 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Implemented CONNECT and SHUTDOWN commands in the client.
3032 * Implemented CLOSE command to the client.
3034 * Added the function silc_idlist_find_server_by_name into the
3035 files silcd/idlist.[ch].
3037 Added the function silc_idlist_find_server_by_conn into the
3038 files silcd/idlist.[ch].
3040 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * DIE command was renamed to SHUTDOWN. Updated the both code
3045 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3046 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3048 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3051 * Added function silc_server_create_connection function to create
3052 connection to remote router. My server implementation actually
3053 does not allow router to connect to normal server (it expects
3054 that normal server always initiates the connection to the router)
3055 so the CONNECT command is only good for connecting to another
3058 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3061 or some other client was kicked from the channel.
3063 Implemented the handling of the notify type to both client
3066 Implemented silc_server_send_notify_kicked to send the KICKED
3067 notify. It is used to send it to the server's primary router.
3069 * Implemented the KICK command into server and client.
3071 * Added `query' argument to the silc_idlist_get_client function
3072 to indicate whether to query the client from server or not if
3075 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3076 to indicate that the client is not channel founder.
3080 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Removed the rng context from SilcPacketContext structure and
3083 changed that the packet routine uses the Global RNG API.
3085 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Added support for quit message that client can "leave" on the
3088 channel when it quits the SILC. It is ditributed inside the
3089 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3091 Added silc_server_free_client_data that will take the
3092 signoff message as argument.
3094 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3096 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Updated parts of the protocol specification to keep it up
3101 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3104 payloads in one packet.
3106 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3107 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3108 use now the new List flag.
3110 * Also deprecated the following packet types: REPLACE_ID,
3111 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3113 * Added list support for Notify packet in server.
3115 * Added silc_server_send_notify_channel_change to send the
3116 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3117 the silc_server_send_replace_id.
3119 * Added silc_server_send_notify_nick_change to send the
3120 NICK_CHANGE notify type. Deprecates the function
3121 silc_server_send_replace_id.
3123 * Added silc_server_send_notify_join to send the JOIN notify type.
3124 Deprecates the function silc_server_send_new_channel_user.
3126 * Added silc_server_send_notify_leave to send LEAVE notify type.
3127 Deprecates the function silc_server_send_remove_channel_user.
3129 * Added silc_server_send_notify_cmode and
3130 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3131 types. Deprecates the silc_server_send_set_mode function.
3133 * Added SERVER_SIGNOFF notify type to indicate that server has
3134 quit. This means that all clients on the channel from that
3135 server will drop. This can be also used when netsplit happens.
3137 Deprecated REMOVE_ID packet type since it is not needed anymore
3140 Added silc_server_send_notify_server_signoff to send the
3141 SERVER_SIGNOFF notify type. Deprecates the function
3142 silc_server_send_remove_id.
3144 Added also silc_server_send_notify_signoff to send the
3145 SIGNOFF notify type.
3147 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3148 SILC protocol from this day on. Changed the protocol
3149 specification as well.
3151 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3152 notify type. It is used between routers to notify about
3153 topic changes on a channel.
3155 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3158 * Partly updated the protocol specification to comply with the
3159 changes now made. It is still though a bit outdated.
3161 * The JOIN notify type now takes one extra argument <Channel ID>.
3162 The packet used to be destined to the channel but now the
3163 JOIN type may be sent as list thus it is impossible to
3164 destine it to any specific channel. By adding this argument
3165 it is again possible.
3167 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Added CREDITS file. The CHANGES and CREDITS file will appear
3170 in the distribution as well.
3172 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3175 types in the server's silcd/packet_receive.c.
3177 * Implemented CMODE and CUMODE to work in router environment.
3179 * Fixed minor encoding and decoding buglet from the
3180 lib/silccore/silcmode.c.
3182 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3185 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3187 * Changed all SilcConfigServer* and silc_config_server* to
3188 SilcServerConfig* and silc_server_config*, respectively.
3191 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * Associated the ID (client or server ID) to the Authentication
3194 Payload to avoid any possibility of forging. Updated the
3195 protocol specification and the code accordingly.
3197 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * The RSA key length is now save to the RsaKey context in the
3200 key generation process in lib/silccrypt/rsa.c. The key length
3201 is now used to figure out the maximum size of the block allowed
3202 to be encrypted/signed.
3204 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3205 is equivalent to the silc_mp_mp2bin but does not allocate any
3208 * Changed silc_mp_mp2bin API to take length argument. If it is
3209 non-zero then the buffer is allocated that large. If zero, then
3210 the size is approximated using silc_mp_sizeinbase, which however
3213 * Created Global RNG API which is global RNG that application can
3214 initialize. After initializing, any routine anywhere in the
3215 code (including library) can use RNG without allocating a new
3216 RNG object. This was done to allow this sort of use of the
3217 RNG in code that has no chance to allocate RNG object. All
3218 applications currently allocate this and many routines in the
3219 library use this. Affected file lib/silccrypt/silcrng.[ch].
3221 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3222 it to use the Global RNG API.
3224 * Defined Authentication Payload into protocol specification that
3225 is used during SILC session to authenticate entities. It is
3226 used for example by client to authenticate itself to the server
3227 to obtain server operator privileges.
3229 Implemented this payload into the lib/silccore/silcauth.[ch].
3230 Implemented also routines for public key based authentication
3231 as the new protocol specification dictates.
3233 Moved definitions of different authentication methods from
3234 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3236 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3237 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3238 silc_pkcs_verify_with_hash functions into the file
3239 lib/silccrypt/silcpkcs.[ch].
3241 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * The client entry's userinfo pointer must be always valid.
3244 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3245 will fail since it requires the userinfo. Now, the userinfo
3246 is allocated as "" if actual userinfo does not exist. Actually,
3247 it must exist and it is totally Ok to drop client connections
3248 that does not announce the userinfo. However, we will make
3249 this workaround for now.
3251 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3252 to return the remote port by socket.
3254 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3257 SILC_SERVER_PENDING_EXEC and added an new macro
3258 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3259 data or when error occurs while processing the pending command.
3261 Added new argument `destructor' into silc_server_command_pending
3262 and to the SilcServerCommandPending object. This destructor is
3263 now called after calling the pending callback or if error occurs
3264 immediately. If error occurs the actual pending callback won't
3265 be called at all - only the destructor. The destructor may be
3266 NULL if destructor is not needed.
3268 All this applies for client library code as well. Similar
3269 changes were made there as well for the pending commands.
3271 In the client, the application must now allocate the
3272 SilcClientCommandContext with the silc_client_command_alloc
3275 * Added reference counter to the SilcServerCommandContext. Added
3276 function silc_server_command_alloc and silc_server_command_dup
3279 Same type of functions added to the client library for the same
3282 * Removed the cmd_ident from IDListData away since it is now
3283 global for all connections. It is the command identifier used
3284 in command sending and with pending commands. The affected file
3287 * Added reference counter to the SilcSocketConnection objecet to
3288 indicate the usage count of the object. The object won't be
3289 freed untill the reference counter hits zero. Currently only
3290 server uses this, and client ignores it. The client must be
3291 set to use this too later. The affected files are
3292 lib/silccore/silcsockconn.[ch]. Added also the function
3293 silc_socket_dup to increase the reference counter.
3295 This was mainly added because it is possible that the socket
3296 is removed underneath of pending command or other async
3297 operation. Now it won't be free'd and proper DISCONNECTING
3298 flags, etc. can be set to avoid sending data to connection that
3299 is not valid anymore.
3301 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3302 the connection. After that it sets SILC_SET_DISCONNECTED.
3303 It is, however, possible that the socket data is not still freed.
3304 The silc_server_packet_process now checks that data is not
3305 read or written to connection that is DISCONNECTED. The socket
3306 get's freed when the reference counter hits zero.
3308 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Changed the client operation API: channel_message operation's
3311 `sender' is now the client entry of the sender, not the nickname
3312 and the `channel' is the channel entry, not the channel name.
3314 In the private_message operation the `sender' is now also the
3315 client entry of the sender not the nickname.
3317 Affected file is lib/silcclient/ops.h and all applications
3318 using the client operations.
3320 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Moved the calling of ops->connect() from connect_to_server_final
3323 into receive_new_id functin since that is the point when the
3324 client is actually allowed to send traffic to network. The
3325 affected file is lib/silcclient/client.c.
3327 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3330 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3331 (if needs broadcasting) instead of broadcasting the packets one
3332 by one which would make a burst in the network traffic.
3334 * Added `broadcast' argument to the functions in silcd/server.[ch]
3335 silc_server_create_new_channel[_with_id] to indicate whether
3336 to send New Channel packet to primary router.
3338 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Added new function into the silcd/server.[ch] files:
3341 silc_server_create_new_channel_with_id to create new channel with
3342 already existing Channel ID.
3344 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3345 lib/silccore/silcpacket.h. This packet is used t send list of
3346 Set Mode payloads inside one packet. Server uses this to set
3347 the modes for the channels and clients on those channels, that it
3348 announced to the router when it connected to it. The protocol
3349 specification has been updated accordingly.
3351 * The silc_server_new_channel did not handle the packet coming
3352 from normal server as it normally does not send that. However,
3353 when it announces its channels it does send it. Implemented
3354 the support for that.
3356 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3357 into the file lib/silccore/id.h.
3359 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Fixed memory leaks in the functions silc_idlist_del_client,
3362 silc_idlist_del_channel and silc_idlist_del_server in the file
3363 silcd/idlist.c. All of those leaked like a sieve.
3365 * Fixed some small memory leaks in the client's function
3366 silc_client_notify_by_server.
3368 * Added functions into silcd/server.c: silc_server_announce_clients,
3369 silc_server_announce_channels and silc_server_announce_server.
3370 These functions are used by normal and router server to announce
3371 to its primary router about clients, channels and servers (when
3372 router) that we own. This is done after we've connected to the
3375 These functions effectively implements the following packet types:
3376 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3377 and SILC_PACKET_NEW_ID_LIST.
3379 * Added new functions into the silcd/packet_receive.[ch]:
3380 silc_server_new_id_list, silc_server_new_channel_list and
3381 silc_server_new_channel_user_list to handle the incoming
3382 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3384 * Added support of changing Channel ID in the function
3385 silc_server_replace_id. If the server that announces a channel
3386 to the router already exists in the router (with same name but
3387 with different Channel ID), router is responsible to send
3388 Replace ID packet to the server and force the server to change
3389 the Channel ID to the one router has.
3391 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3392 client that the Channel ID has been changed by the router. The
3393 normal server sends this to the client. Client must start using
3394 the new Channel ID as the channel's ID.
3396 Implemented handling of this new type into lib/silcclient/client.c
3397 into the function silc_client_notify_by_server.
3399 * Added new function silc_idlist_replace_channel_id into the files
3400 silcd/idlist.[ch] to replace the Channel ID.
3402 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Call silc_server_command_identify_check always when processing
3405 the IDENTIFY command in silcd/command.c
3407 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3410 send keepalive packets. The packet can be sent by clients,
3411 servers and routers.
3413 Added function silc_socket_set_heartbeat into the file
3414 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3415 If not set, the heartbeat is not performed. The actual
3416 heartbeat is implemented in the low level socket connection
3417 library. However, application is responsible of actually
3420 Added silc_server_send_heartbeat to send the actual heartbeat
3421 packet into silcd/packet_send.[ch]. Server now performs
3422 keepalive with all connections.
3424 * Added silc_task_get_first function into lib/silcutil/silctask.c
3425 to return the timeout task with shortest timeout. There was a bug
3426 in task unregistration that caused problems. TODO has been
3427 updated to include that task system must be rewritten.
3429 * The client library will now resolve the client information when
3430 receiving JOIN notify from server for client that we know but
3431 have incomplete information.
3433 * Rewrote parts of silc_server_remove_from_channels and
3434 silc_server_remove_from_one_channel as they did not remove the
3435 channel in some circumstances even though they should've.
3437 * Encryption problem encountered in server:
3439 The LEAVE command used to send the Channel Key packet to the
3440 router immediately after generating it. However, the code
3441 had earlier sent Remove Channel user packet but not immediately,
3442 ie. it was put to queue. The order of packets in the router
3443 was that Channel Key packet was first and Remove Channel User
3444 packet was second, even though they were encrypted in the
3445 reverse order. For this reason, MAC check failed. Now, this
3446 is fixed by not sending the Channel Key packet immediately but
3447 putting it to queue. However, this is more fundamental problem:
3448 packets that are in queue should actually not be encrypted
3449 because packets that are sent immediately gets encrypted
3450 actually with wrong IV (and thus MAC check fails). So, packets
3451 that are in queue should be encrypted when they are sent to
3452 the wire and not when they put to the queue.
3454 However, the problem is that the current system has not been
3455 designed to work that way. Instead, the packet is encrypted
3456 as soon as possible and left to the queue. The queue is then
3457 just purged into wire. There won't be any fixes for this
3458 any time soon. So, the current semantic for packet sending
3461 o If you send packet to remote host and do not force the send
3462 (the packet will be in queue) then all subsequent packets to the
3463 same remote host must also be put to the queue. Only after the
3464 queue has been purged is it safe again to force the packet
3467 o If you send all packets immediately then it safe to send
3468 any of subsequent packets through the queue, however, after
3469 the first packet is put to queue then any subsequent packets
3470 must also be put to the queue.
3472 Follow these rules and everything works fine.
3474 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Added new function silc_server_remove_clients_by_server to
3477 remove all client entries from ID list when the server connection
3478 is lost. In this case it is also important to invalidate all
3479 client entires as they hold the invalid server entry. This
3480 fixes fatal bug when server has lost connection and will reconnect
3483 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Made some sanity checks to silc_server_daemonise like to check
3486 whether the requested user and group actually exists.
3488 * Added sanity check to SKE's silc_ske_responder_finish to check
3489 that the public and private key actually is valid.
3491 * Invalidate the client's nickname when receiving Replace ID
3492 packet and the Client ID is being replaced. This means that the
3493 server will query the nickname if someone needs it (client)
3496 * Sort the ID Cache in client library when the ID Cache data
3497 has changed (needs sorting).
3499 * Do not allow for SILC client to create several connections to
3500 several servers. The client does not support windows right now
3501 and generating multiple connections causes weird behaviour.
3503 Irssi-silc client does support windows and can handle several
3504 connections without problems, see: www.irssi.org and SILC plugin.
3506 * Fixed some places where client was added to the IDList. The
3507 rule of thumb is following (in order to get everything right):
3508 If the client is directly connected local client then the
3509 `connection' argument must be set and `router' argument must be
3510 NULL to silc_idlist_add_client function. If the client is not
3511 directly connected client then the `router' argument must
3512 bet set and the `connection' argument must be NULL to the
3513 silc_idlist_add_client function.
3515 * The funtion silc_server_packet_send_local_channel actually did
3516 not check whether the client was locally connected or not. It
3517 does that now. Fixed a bug related to LEAVE command.
3519 * Fixed Remove Channel User payload parsing bug in server's
3520 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3522 * The server's silc_server_save_channel_key now checks also the
3523 global ID list for the channel as it might not be in the local
3524 list. Fixed a bug related to LEAVE command.
3526 * Is this the end of the [<unknown>] buglet that has been lurking
3527 around for a long time? A little for loop fix in server's
3528 silc_server_command_whois_parse that is used by both IDENTIFY
3529 and WHOIS command. At least, this was a clear bug and a cause
3530 of one type of [<unknown>] buglet.
3532 * WHOIS and IDENTIFY commands call the function
3533 silc_server_command_[whois/identify]_check function even if
3534 we are not router server.
3536 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Added --with-gmp configuration option. If set the GMP
3539 is always compiled in the SILC source tree. If not set then
3540 it is checked whether the system has the GMP3 installed. If
3541 it has then the GMP won't be compiled (the system's headers
3542 and library is used), if it doesn't have it then the GMP is
3543 compiled in the SILC source tree.
3545 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Changed RSA private exponent generation to what PKCS #1
3548 suggests. We try to find the smallest possible d by doing
3549 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3550 not security fix but optimization.
3552 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Added new config entry [Identity] to fork the server and run
3555 it as specific user and group. A patch from Bostik.
3557 * Imported Dotconf configuration library into lib/dotconf.
3558 This will be used to create the SILC configuration files later.
3559 It will appear in the distsribution after this commit.
3561 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * A big code auditing weekend happening. Auditing code for
3564 obvious mistakes, bugs and errors. Also, removing any code
3567 Removed files for being obsolete:
3569 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3570 inline in the file lib/silcutil/silcbuffer.h)
3572 o lib/silcutil/silcbufutil.c (the header has inline versions)
3574 Changed code to fix possible error conditions:
3576 o The buffer formatting routines now check that the destination
3577 buffer really has enough space to add the data. This applies for
3578 both buffer formatting and unformatting
3579 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3580 unformatting was changed to accomodate following rules:
3581 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3582 sent to the function while XXX_*STRING will not allocate or copy
3583 the data into the buffer. Instead it sets the pointer from the
3584 buffer into the pointer sent as argument (XXX_*STRING used to
3585 require that the pointer must be allocated already). This change
3586 makes this whole thing a bit more consistent and more optimized
3587 (note that the data returned in the unformatting with XXX_*STRING
3588 must not be freed now). The routines return now -1 on error.
3590 o Tried to find all code that use buffer_format and buffer_unformat
3591 and added return value checking to prevent formatting and
3592 especially unformatting errors and possible subsequent fatal
3595 o Changed ske->x and ske->KEY to mallocated pointers in
3596 lib/silcske/silcske.h. Fixed possible data and memory leak.
3598 o Added return value checking to all *_parse* functions. Fixed
3599 many memory leaks as well.
3601 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3602 so that buffer overflows would not happen. All code now also
3603 checks the return value as it can fail.
3605 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added reconnection support to server if the normal server looses
3608 its connection to the router (for example if router is rebooted).
3609 The server performs normal reconnection strategy implemented
3610 to the server. Affected file silcd/server.c.
3612 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added new packet type SILC_PACKET_SET_MODE that is used to
3615 distribute the information about changed modes (for clients,
3616 channels and clients channel modes) to all routers in the
3617 network. Updated the protocol specification accordingly.
3619 Added functions into silcd/packet_send.c and
3620 silcd/packet_receive.c: silc_server_send_set_mode,
3621 silc_server_set_mode.
3623 Added new files silcmode.[ch] into lib/silccore that implements
3624 the encoding and decoding of Set Mode Payload. Added new type
3625 SilcSetModePayload. Moved the definitions of different modes
3626 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3628 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Oops, a little mistake in server's connection authentication
3631 protocol. The protocol is not ended with FAILURE but with
3632 SUCCESS if the authentication is Ok. :) Affected file is
3635 * Implemented NICK_CHANGE notify handling in server in the file
3636 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3637 the local clients on the channel. After the changing nickname
3638 in router environment snhould work and the [<unknown>] nickname
3639 should appear no more.
3641 The silc_server_replace_id function that receives the Replace ID
3642 payload now sends the NICK_CHANGE notify type also in the file
3643 silcd/packet_receive.c
3645 * Changed WHOIS and IDENTIFY command to support the maximum amount
3646 of arguments defined in protocol specs (3328 arguments). This
3647 fixed a bug that caused problems when there were more than three
3650 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added extra parameter, command identifier, to the
3653 silc_client_send_command so that explicit command identifier
3656 Changed that ID list routines uses specific command identifier
3657 when sending WHOIS/IDENTIFY requests to the server so that they
3658 can be identified when the reply comes back.
3660 Affected files lib/silcclient/command.[ch],
3661 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3663 * Added `sender' argument to silc_server_packet_send_to_channel
3664 to indicaet the sender who originally sent the packet to us
3665 that we are now re-sending. Ignored if NULL. Affected file
3666 silcd/packet_send.[ch].
3668 * Added some server statistics support in silcd/server_internal.h
3669 SilcServerStatistics structure and around the server code. Also
3670 send some nice statistics information when client is connecting
3673 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Fixed channel ID decoding in server's JOIN command reply in
3676 silcd/command_reply.c
3678 * Fixed braodcasting of replace ID payload to not to send it if
3679 we are standalone server in silcd/packet_receive.c.
3681 * Fixed all channel message sending routines to not to send
3682 packets to clients that has router set, since they are routed
3683 separately in the same function earlier. Affects file
3684 silcd/packet_send.c and all channel packet sending functions.
3686 * In USERS reply, res_argv[i] are not allocated, the table
3687 is allocated. Thus changed that free the table, not its
3690 * In server's whois_check and identify_check if the client is
3691 locally connected do not send any WHOIS commands - they are not
3694 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Fixed some minor bugs in client when sending WHOIS command. The
3697 arguments was in wrong order.
3699 * Removed statis function add_to_channel from server in
3700 silcd/command.c that was previously used with the joining but
3703 * Tested USERS command in router environment successfully with two
3704 routers, two servers and two clients.
3706 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Reorganized the USERS command and command reply in client library
3709 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3710 When the command is given by user we register a pending command
3711 callback that will reprocess the command after the reply has been
3712 received from the server. When reprocessing the packet we then
3713 display the information. Thus, the USERS information is displayed
3714 now in the command callback instead of in the command reply
3715 callback. The processing of the command is same as previously
3716 when server has sent the command reply in the JOINing process.
3718 * Added to USERS command in silcd/command_reply.c to join the client,
3719 we didn't use to know about, to the channel after we've created
3720 a client entry for it. Also, for clienet we did know already still
3721 check whether it is on the channel or not and add it if not.
3723 * Removed silc_server_command_join_notify as the function and its
3726 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * Changed the client's pending command handling to the same as the
3729 server's pending command handling. It is also now possible to
3730 execute command reply functions from other command reply
3731 function as the function callbacks for commands and command
3732 replies are one and same. The pending commands are not static
3733 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3734 in client connection context. Thus, pending commands are server
3735 connection specific as it is convenient.
3737 Changed the function silc_client_command_pending and
3738 silc_client_command_pending_del and added new function
3739 silc_client_command_pending_check. Removed the
3740 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3743 * Added cmd_ident, current command identifier, to the client
3744 connection context in lib/silcclient/client.h to keep track on
3745 command identifiers used in command sending. Client's command reply
3746 function handling now supports the mandatory command identifiers.
3748 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3749 funtions in client to fully support pending command callbacks.
3751 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3752 as one of the arguments to the application in the command reply
3755 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3756 before first releasing SILC but came back. Now it is removed again
3757 and should come back nomore. The FORWARDED flag was used only
3758 by the JOINing procedure by forwarding the command packet to router.
3759 Now, the JOINing procedure has been changed to more generic (due
3760 to various router environment issues) and FORWARDED is not needed
3761 anymore for anything. The protocol specification is yet to be
3764 Now, removed silc_server_packet_forward from server and the flag
3765 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3767 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Renamed NAMES command to USERS command. The NAMES was named that
3770 due to historical reasons. Now it is renamed. Also, rewrote
3771 parts of the USERS command. The nickname list is not sent anymore
3772 by the server. Only Client ID and mode lists are sent in the USERS
3773 command. Changed this also to the protocol specification.
3775 The client now resolves the names and stuff after it receives
3776 the USERS list from the server when joining to the channel.
3778 * WHOIS and IDENTIFY commands has been changed to support multiple
3779 Client ID's per command. One can now search for multiple users
3780 in the network by sending only one WHOIS or IDENTIFY command.
3781 Changed the code and the protocol specifications.
3783 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3784 uses silc_server_command_whois_parse to parse the request. */
3786 * If normal server, do not parse the WHOIS and IDENTIFY requests
3787 before sending it to the router. Saves some time.
3789 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Fixed JOIN command on client library. Wrong number of arguments
3792 used to crash the client.
3794 * Added silc_server_channel_has_global function to check whether
3795 channel has global users or not.
3797 * Added silc_server_channel_has_local function to check whether channel
3798 has locally connected clients on the channel.
3800 * The silc_server_remove_from_one_channel now checks whether the
3801 channel has global users or not after given client was removed from
3802 the channel. It also checks whether the channel has local clients
3803 on the channel anymore. If it does not have then the channel entry
3804 is removed as it is not needed anymore.
3806 * The silc_server_notify now checks on JOIN notify whether the joining
3807 client is one of locally connected or global. If it is global then
3808 the channel has now global users on the channel and that is marked
3809 to the channel entry. Also, it now saves the global client to
3810 global list who is joining and JOINs it to the channel. This is
3811 for normal server, that is.
3813 Changed silc_server_send_notify_on_channel,
3814 silc_server_packet_relay_to_channel and
3815 silc_server_packet_send_to_channel check if we are normal server
3816 and client has router set (ie. global client) do not send the
3817 message to that client, as it is already routed to our router.
3819 * Implemented LEAVE notify type handling in silc_server_notify
3822 * Tested LEAVE command in router environment successfully. Tested
3823 with two routers, two servers and two clients.
3827 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3829 * Implemented SIGNOFF notify type handling in silc_server_notify
3832 * silc_server_remove_id now removes the client entry from all channels
3833 it has joined and thusly sends SIGNOFF notify type.
3835 * Rewrote the NAMES list generation in server by removing two excess
3836 loops. The lists are created now inside one loop.
3838 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * silc_server_remove_channel_user checks now also global list
3841 for channel and client.
3843 * silc_server_new_channel_user checks now both local and global
3844 list for channel and client. Fixed a bug in client id decoding.
3845 Used to decode wrong buffer.
3847 * silc_server_channel_message checks now both local and global
3848 list for channel entry.
3850 * Tested channel joining (hence JOIN) in router environment
3851 successfully. Tested with two routers, two servers and two
3854 * Tested channel message sending in router environment successfully.
3856 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Added silc_server_save_channel_key into server.[ch] to save the
3859 received channel key in Channel Key payload processing. It is
3860 also used in JOIN command reply handling.
3862 Equivalent function silc_client_save_channel_key added into
3863 client.[ch] into client library.
3865 * Changed JOIN command reply to send information whether the channel
3866 was created or not (is existing already) and the channel key
3867 payload. Changed protocol specs accordingly.
3869 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3870 the request was sent by ID and not by nickname. Crashed on
3873 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3876 now correctly save the received data.
3878 * silc_server_free_sock_user_data now notifies routers in the
3879 network about entities leaving the network.
3881 At the same time implemented functions silc_server_remove_id
3882 and silc_server_send_remove_id to receive and send REMOVE_ID
3883 packets. The packet is used to notify routers in the network
3884 about leaving entities. The ID removed will become invalid in
3887 * Added function silc_idlist_del_server into server. Removes and
3888 free's server entry from ID list.
3890 * silc_server_private_message function now checks, if we are router,
3891 that the destination ID really is valid ID, naturally.
3893 * In router when NEW_ID packet is received (for new client) the
3894 hash of the Client ID is saved in the ID Cache but the
3895 client->nickname is set to NULL, instead of putting the hash
3898 IDENTIFY command now also checks that client->nickname must be
3899 valid. If it is not if will request the data from the server who
3900 owns the client. Added new function
3901 silc_server_command_identify_check.
3903 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3904 to set the command to already allocated Command Payload.
3906 * Tested private message sending in router environment with two
3907 routers, two servers and two clients. Fixed minor bugs and now
3910 * Fixed segfault from client's NAMES command. Used to crash if
3913 * Forwarded packets must not be routed even if it is not destined
3914 to the receiver. Changed server code comply with this.
3916 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Added `require_reverse_mapping' boolean value to ServerParams
3919 structure. If TRUE (not default) the server will require that
3920 the connecting host has fully qualified domain name.
3922 If the reverse mapping is not required and hostname could not be
3923 found the IP address is used as hostname.
3925 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Implemented version string checking to both client and server.
3928 The check is incomplete currently due to the abnormal version
3929 strings used in development version of SILC.
3931 * Changed all command functions in server to use the new
3934 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Changed char *data to unsigned char *data in ID Cache system to
3937 support binary data as ID Cache data. Changed code to support
3938 binary data in lib/silccore/idcache.c.
3940 * Renamed silc_server_packet_relay_command_reply to
3941 silc_server_command_reply as it is normal packet receiving
3942 function. Rewrote the function to accept command replys for
3943 servers and not only for clients.
3945 * Mark remote router always as registered server if we are connecting
3946 to it. Otherwise, commands sent by the router to us are ignored.
3948 * All ID List find routines now returns the ID Cache Entry pointer
3949 as well if requested.
3951 * WHOIS command works now in router environment, tested with two
3952 routers, two servers and two clients.
3954 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3955 in router environment (as it is almost equivalent to WHOIS) but
3956 hasn't been tested thoroughly. Added new functions:
3958 silc_server_command_identify_parse
3959 silc_server_command_identify_send_reply
3960 silc_server_command_identify_from_client
3961 silc_server_command_identify_from_server
3963 * Disabled route cache adding because adding two different ID's with
3964 same IP replaces the old cache entry thus giving wrong route.
3965 The entry->router->connection is always the fastest route anyway
3966 so route cache may not be needed. Of course, new routes maybe
3967 established after receiving the ID when the entry->router->connection
3968 might not be anymore the most optimal.
3970 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Add route cache for received ID for fast routing.
3974 * Added silc_server_packet_route to route received packet on router
3975 that is not destined to us.
3977 * Renamed silc_server_get_route to silc_server_route_get.
3979 * Added id_string and id_string_len fields into SilcServer to
3980 include encoded ServerID for fast comparing without excess
3981 encoding of the ID's.
3983 * Cleaned up WHOIS command on server side. Added following static
3986 silc_server_command_whois_parse
3987 silc_server_command_whois_check
3988 silc_server_command_whois_send_reply
3989 silc_server_command_whois_from_client
3990 silc_server_command_whois_from_server
3992 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3993 arguments in command replies. All command functions should be
3994 updated to use this macro.
3996 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Minor typo fixes on command reply handling on server.
4000 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Added silc_server_command_add_to_channel internal routine to add
4003 the client to the channel after router has created the channel and
4004 sent command reply to the server.
4006 * Added generic silc_server_send_command to send any command from
4009 * Use static buffer with ID rendering instead of duplicating data.
4011 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Fixed a channel user mode bug when joining to a channel server gave
4014 everybody channel founder rights, oops.
4016 * We mark ourselves as the router of the incoming server connection
4017 if we are router ourselves. This way we can check in some packet
4018 sending functions whether it is locally connected server. For
4019 incoming router connections we put NULL.
4021 * For router sending packets locally means now always sending the
4022 packet cell wide; to local clients and local servers. For normal
4023 server sending packet locally means sending it to only local
4026 * Fixed the JOIN command to really work in router environment. If the
4027 channel is created it is always created by the router. Router is
4028 also responsible of making the initial joining to the channel,
4029 sending JOIN notify to the sending server and distributing
4030 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4031 does not exist server doesn't do anything else but forward the
4032 command to the router which performs everything.
4034 * Added silc_server_send_channel_key function to send the Channel Key
4037 * Added silc_server_create_channel_key to create new channel key. The
4038 channel key is now re-generated everytime someone joins or leaves
4039 a channel, as protocol dictates. Note: channel->key_len is the
4042 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4045 packet_receive.[ch] to separate packet sending and receiving
4046 routines. The server.[ch] now includes everything else including
4047 actual packet processing (writing and reading data) and other
4050 Renamed silc_server_private_message_send_internal to
4051 silc_server_send_private_message. The routine is still though
4052 used only to relay private messages as server does not send
4053 private messages itself.
4055 Renamed silc_server_new_channel to silc_server_create_new_channel
4056 and added new function sicl_server_new_channel that handles the
4057 incoming New Channel packet. Added also new sending function
4058 silc_server_send_new_channel to send New Channel Payload.
4060 * Added new function silc_server_notify to process incoming notify
4061 packet to the server/router. Server may then relay the notify
4062 to clients if needed.
4064 * Added new function silc_server_new_channel_user to process incoming
4065 New Channel User packet. Router will redistribute the packet and
4066 send JOIN notify to its local clients and locally connected servers
4067 if needed. Normal server will send JOIN notify to its local client
4068 on same channel when received this packet. Added also corresponding
4069 sending function silc_server_send_new_channel_user to sent the
4072 * Added boolean route argument to send_notif_to_channel and
4073 packet_send_to_channel functions to attempt to route the packet
4074 if it is TRUE and send only locally if it is FALSE.
4076 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * silc_server_replace_id now broadcasts the received replace ID
4079 packet if it is not broadcast packet already. The router must
4080 broadcast to inform other routers about changed ID.
4082 * Added backpointer to server's router into SilcServer context in
4083 silcd/server_internal.h.
4085 * Fixed silc_server_packet_broadcast to send correct broadcast
4088 * The channel key is now distributed to the local client as soon
4089 as it is received from the router (in router environment) so that
4090 no other packet may be sent for the channel until client has
4093 * silc_server_remove_channel_user now broadcasts the received
4094 Remove Channel User packet if it is not broadcast packet already.
4095 The router must broadcast to inform other routers about removed
4098 * Added users field into SilcPacketContext that is a reference count
4099 of the context. One can increase the reference count by calling
4100 silc_packet_context_dup which is now changed to just increase the
4101 reference count instead of duplicating the data. The reference
4102 count is decresed by calling silc_packet_context_free that will
4103 free the data after the reference count hits zero.
4105 For now on the packet context and everything allocated into it
4106 (including the raw packet from network) must be freed by calling
4107 the new silc_packet_context_free function. Added also new function
4108 silc_packet_context_alloc that must be used now to allocate the
4109 context. This also means that if a routine is asynchronous from
4110 silc_[client/server]_packet_parse_type the packet context must
4111 be duplicated by calling silc_packet_context_dup. Otherwise it
4112 gets free'd after silc_[client/server]_packet_parse_type returns.
4113 Also, one must remember that if packet is duplicated then its
4114 reference count must be decresed by calling the free function as
4115 many times as it was duplicated.
4117 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4118 from both client and server.
4120 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Made joining to a channel working in router environment.
4124 * Cleaned up JOIN command on server side and create function
4125 silc_server_command_join_channel internal routine to make the
4128 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Changed silc_command_pending list to SilcDList. Also, added
4131 `ident' field to SilcServerCommandPending structure to identify
4132 the reply and to call correct callback.
4134 Added silc_server_command_pending_check function to replace the
4135 corresnponding macro. The silc_command_pending list is not
4138 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4139 to set identifier to previously allocated Command Payload. It
4140 is used to set identifier for command when resending Command
4143 * Added silc_command_payload_encode_payload to encode Command
4144 Payload buffer from SilcCommandPayload structure.
4146 * Added silc_argument_payload_encode_payload to encode Argument
4147 payload buffer from SilcArgumentPayload structure.
4149 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Changed WHOIS command to support router connection on server side.
4152 The whois request is always sent to router unless the server is
4153 standalone server. After server has received the reply from the
4154 router will it send the reply to the client.
4156 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4157 broadcast received broadcast packet. The function is used only
4158 by router. The broadcast packet is always sent to the router's
4161 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4162 render given ID to printable string, for log files for example.
4164 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Made basic router to router connections working. At least they
4167 can now connect to each other but nothing really works the way
4168 they are supposed - yet.
4170 * Added new initiator token to RouterConnection configuration
4171 file in silcd/serverconfig.[ch]. It is used to tell whether we
4172 are the initiator to the remote router or whether we'll expect
4173 the other end to connect.
4175 * Moved registering of listener task to silc_server_init, hence
4176 the server starts listenning as soon as it is run, even if it
4177 does not have connections to other routers. Let's see how well
4180 * Changed default connection retry timeouts for more suitable in
4183 * Removed cipher and such arguments from silc_idlist_add_client
4184 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4185 Added new function silc_idlist_add_data to add the keys and stuff
4188 * Added SilcIDListData structure and added it to SilcClientEntry
4189 and SilcServerEntry as their first field in the structure. This
4190 way we can explicitly cast the ID entries to the SilcIDListData
4191 structure and get common data for the entries. In past, we had
4192 to first check what type of connection it is and then cast it to
4193 correct ID entry type. Now, we can directly cast the opaque
4194 pointer to the SilcIDListData (no matter what ID entry it actually
4195 is) and get the data needed.
4197 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4200 in some circumstances even if threre were timeout tasks, though not
4201 IO tasks, but tasks anyway. Now fixed.
4203 * Defined SilcServerConnection structure to hold connection specific
4204 stuff about directly connected servers and routers. The definition
4205 is currently in silcd/server_internal.h. I thought about having
4206 a bit more important role fro this struct but for now it is used
4207 only when connecting to other server (or router actually).
4209 * Added connecting retry support in server when connecting to
4210 router(s). The retry feature implement exponential backoff
4211 algorithm. Also, added SilcServerParams structure to hold default
4212 parameters for server. For now, it include these retry settings
4213 and are hard coded. After server is moded to be as Silc Server
4214 Library this structure will be more important.
4216 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Changed client librarys channel->clients table to SilcList and
4219 changed code accordingly.
4221 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Changed client's channel table to SilcList and changed code
4224 accordingly. Also changed SilcChannelClientEntry to include back-
4225 pointer to the channel so that client entry can use that structure
4226 as list as well and we have fast cross-reference to the channel.
4227 This change dramatically decreased the complexity of channel
4228 handling with client entry and vice versa (removed one extra
4229 loop when searching for channel entry from many functions).
4231 * Changed server->sim from table to SilcDList and changed code
4234 * NAMES command can now be used from user interface. It will show
4235 the user list on the channel, neatly.
4237 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4238 Code now saves realname of the user if it becomes available.
4240 * Renamed configure.in to configure.in.pre and made ./prepare
4241 script to automatically add correct version string to
4242 configure.in which it creates from configure.in.pre.
4244 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * NAMES command reply now shows users mode with the nickname when
4249 * Moved silc_client_ch[u]mode[_char] functions from
4250 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4251 place sucks, they are utility functions and should be in some
4254 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4256 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4259 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added TRQ (efficient deque and list library) into lib/trq. This is
4264 a very good list library that is currently used in the SILC. Defined
4265 SilcList API over the library because I didn't like the API very
4266 much. See lib/trq/silclist.h for the API and examples of how to
4267 use the API. Fixed various places in the code to use the new
4268 SilcList API. The SilcList is meant for lists that has a structure
4269 already defined as a list. It is not suitable to add just some
4270 context to the list (in TRQ, the context is the list actually).
4272 So, I defined SilcDList that can be used for the purpose where
4273 predefined list structure does not exit. This can be used as
4274 such list. Now some context just can be added to the SilcDList.
4275 Currently this list is not used in the SILC just yet, though there
4276 are a lot places where this can replace dynamically allocated
4277 tables and I will fix these places, later, to use SilcDList.
4278 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4279 and use TRQ internally).
4281 Also fixed some annoying warning messages that the original TRQ
4282 code generated. Also minor changes to TRQ's Makefile.in.
4284 * Added support for querying by Client ID to both WHOIS and
4285 IDENTIFY commands into server, as required by the protocol.
4287 * Removed method function pointers from SilcBuffer structure. They
4288 weren't used to anything and just increased the context size for
4289 no good reason. This change also made silc_buffer_alloc and
4290 silc_buffer_free functions inline functions.
4292 * Disabled command flooding detection support until it's fixed so
4293 that it accepts commands in but does not execute them more than once
4296 * Added silc_net_localhost(), to return local hostname, into
4297 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4298 that must be initialized before calling silc_client_init.
4300 * Added new function: silc_server_send_notify_on_channels to send
4301 notify messages to all channels client has joined. It is assured
4302 that the message is sent only once per client.
4304 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4305 lib/silcutil/silcutil.[ch] as silc_format function. The new
4306 function is generic and is used by server as well, not only by
4307 the logging routines.
4309 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4310 the provided version string was not acceptable. Added new function:
4311 silc_ske_check_version into lib/silcske/silcske.h. The function
4312 must be implemented by the application (client or server) and it
4313 does not reside in the SKE library. The function checks the version
4314 string remote end sent.
4316 * Added back pointers (to opaque context and to SilcSocketConnection)
4317 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4319 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4320 duplicate packet context structure.
4322 * Changed `notify' client operation to send same arguments as client
4323 receives from server except for ID's. ID's are mapped to correct
4324 ID entry and that is returned. Also, if channel entry is not sent
4325 by server but the notify is for channel the channel entry is sent
4326 to application (otherwise application doesn't know that it is for
4327 channel (library gets it from packet's Destination ID)).
4329 * Added silc_client_remove_from_channels into client library to
4330 remove a client from all channels it has joined to. Used when
4331 received SIGNOFF notify from server. Added also new function
4332 silc_client_replace_from_channels to replace old ID entry with
4333 new ID entry on all channels. Used when received NICK_CHANGE
4336 * Fixed ID Cache list handling in silc_idlist_get_client in
4337 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4338 to get (or query) client by ID.
4340 * Updated TODO list.
4342 * Added connection authentication status message defined by the
4343 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4344 support for these into the code in client and server side.
4346 * Added generic function silc_client_send_command to send any command
4347 with variable argument list. Application should use this function
4348 to send commands if the command functions provided by the library
4349 does not suite for the application's user interface needs.
4351 * Added new `failure' client operation. Application is notified about
4352 received failure packet if client is executing a protocol. In this
4353 case the protocol's execution has failed.
4355 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4356 is required by the protocol.
4358 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4359 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4362 * Added status flag to SilcSKE object to indicate realtime status
4363 of the SKE protocol.
4365 * Application receives now exactly same command reply arguments as
4366 the library receives from server. However, if ID is received the
4367 corresponding ID entry is returned to the application (eg. Client
4368 ID is mapped to correct SilcClientEntry entry and that is returned).
4369 Changed command_reply client operation due to this change.
4371 * Changed all ID's in commands and in command replys as ID Payloads.
4372 Change affected both client and server side codes.
4374 All ID's sent in SILC network (with execption of ID's in SILC
4375 Packet header) are sent in ID Payload to support variable length
4378 * Server now notifies nick changes and notifies all clients on
4379 the channels about the new nickname (about the new Client ID,
4382 * Implemented CMODE command to change channel modes. Supports all
4383 channel modes defined by the protocol specs except ban and invite
4384 lists. (Also, private channel key mode is supported but support for
4385 setting private channel key in client is missing, thus, this mode
4386 has no effect on client side (except that server requires that the
4387 client uses private channel key and normal channel traffic does not
4390 Also, invite mode works per se, but INVITE command does not work
4391 yet correctly, so you can set channel as invite only channel but
4392 inviting clients to the channel does not work (it is yet to be
4393 thought what's the best way to do it).
4395 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4396 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4397 Implemented CUMODE command to change user's mode on the channel.
4398 Supports all modes defined by the protocol specs.
4400 * Added NAMES command reply to return users modes on the channel.
4402 * Removed unnecessary and slow ciphers from lib/silccrypt.
4404 * Set SO_KEEPALIVE option to connection sockets by default.
4406 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4408 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4409 redefined the Notify Payload into protocol specs.
4411 * Added silc_id_payload_parse_id to get ID directly from raw
4414 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4417 accept searching by Client ID as well.
4419 * Added support for LEAVE and SIGNOFF notify types in client library.
4421 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4422 to parse ID Payload from raw data.
4424 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Added flags parameter into silc_ske_assemble_security_properties
4427 function in lib/silcske/silcske.[ch].
4429 * Changed notify client operation to fit better for notify messages
4430 sent by server. The notify payload received from server is now
4431 passed to the application (after parsing it to SilcNotifyPayload).
4432 It is application's responsibility to retrieve the arguments
4433 from the payload and show the message the way it wants. The message
4434 sent by server is implementation specific.
4436 * Changed public keys to comply with the protocol specification.
4437 Old public keys are not supported anymore and are not compatible.
4439 * Removed nickname from Channel Payload as the latest draft removed
4440 it. The client must resolve the nickname from the NAMES command
4441 reply received when it joined the channel.
4443 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4445 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Fixed some errors in protocol specification drafts.
4449 * Created lib/silccore/silcnotify.c to implement Notify Payload
4450 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4451 generic payloads described by protocol specifications. The file
4452 includes implementations for ID Payload and Argument Payload.
4454 * Changed Command Payload implementation to use the new Argument
4455 Payload. Changed command_xxxx_payload to command_payload_xxxx
4456 to comply with SILC coding conventions.
4458 * Added suppport for Argument Payload handling in Notify Payload
4459 implementation as protocol requires it. Added the new support
4460 into server and client lib as well.
4462 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added support for multiple nicknames on same channel. [n] is
4465 added locally to the nickname if there are more than one same
4466 nicknames on the channel.
4468 * Server now sends all nicknames that matched WHOIS request.
4469 Client also shows the list received from server.
4471 * Added TOPIC command to client side. User can now set and show
4472 current topic on channel.
4474 * Added MOTD command to client and server. Also, server sends the
4475 motd when client connects to the server.
4477 * Changed version strings to comply ISO 8601.
4479 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Fixed protocol error handling in client library. It should now
4482 cope even if the SKE fails for some reason.
4484 * Made new protocol specification drafts for submitting to IETF.
4486 * Implemented TOPIC command to server in silcd/command.c.
4488 * Added two new notify types into lib/silccore/silcnotify.h:
4489 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4490 notify nickname change and topic setting/change on a channel.
4492 * API change of command_reply operation in client library. The
4493 application gets now the status type received from server as well.
4495 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4499 * Cras fixed and optimized the packet handling even further and
4500 it should work now. Minor change to the prototype of function
4501 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4503 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Added new function into lib/silcutil/silcschedule.[ch]:
4506 silc_schedule_with_fd to select() a specified fd. The function
4507 returns after timeout expires or data arrives or goes. The
4508 function is used by packet routines to wait that all data is
4509 received from network.
4511 * Fixed data reading from network in lib/silccore/silcpacket.c.
4512 The code now assures that all data is read from the fd and then
4513 continues packet processing. This was a bug fix since the code
4514 used to drop some data in some circumstances.
4516 * Added new function into lib/silcclient/client.[ch]:
4517 silc_client_start_key_exchange to start key exchange after
4518 connection has been established to server. The code internally
4519 now uses this funtion but its main purpose was to provide it
4520 for applications that perform their own connecting. After
4521 application has created a connection it merely calls this
4522 function to start the key exchange between client and server.
4523 The library takes care of everything else after that.
4525 Updated also lib/silcclient/README to explain the usage of
4528 * Do not send to application information that connection has
4529 been established. Application gets notified it by connect
4532 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Applied cras's patch to add silc_schedule_one function. The
4535 function runs scheduler once and returns.
4537 * Fixed the scheduler after cras messed it up. The timeout
4538 handling works now as it's supposed to work.
4540 * Added into lib/silccore/ silcnotify.h to include notify
4541 message types support. Changed silc_server_send_notify*
4542 functions, in server.[ch], to support those new notify types.
4543 Added the support for the notify types into client library,
4544 as well. Added new notify client operation into ops.h in
4547 * Changed silc_server_packet_send_to_channel to send normal
4548 packets instead of just channel message packets. The function
4549 is now used to send the notify packets to channels. It is not
4550 used to send channel message packets anymore, as server never
4553 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4554 va_arg()s as it seems to require it nowadays. I guess, if SILC
4555 is compiled with older va_arg() the new code should work anyway.
4557 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Splitted core library. Core library (lib/silccore) includes
4560 now only SILC protocol specific core (and common) components.
4561 Created new utility library (lib/silcutil) that includes more
4562 generic purpose stuff. The stuff for util library was taken
4563 from the old core library. This was minor and easy split.
4565 * Created SILC Client Library (lib/silcclient) that includes
4566 implementation of the SILC client without user interface. This
4567 was major move from silc/ directory. The code has been changed
4568 so that it is transparent towards the user interface. The
4569 silc/ directory includes now the same user interface as before
4570 and it uses the new client library. Read lib/silcclient/README.
4571 Basicly, the client library performs everything else related
4572 to SILC except user interface handling. Also, configuration
4573 files are considered to be part of user interface and library
4574 does not handle them.
4576 This change also changed a lot of structures, function naming etc.
4577 Most important change was that SilcClientWindow object was
4578 renamed to SilcClientConnection in the client library. Created
4579 also new file lib/silcclient/ops.h. Also added new files
4580 silc/local_command.[ch] and silc/client_ops.[ch].
4582 All these changes were made to make it easier for user interface
4583 designers to create what ever user interface for the SILC client
4586 It is also expected that the server will be moved to lib
4587 directory as well and SILC Server Library will be created;
4588 sometimes in the future.
4590 * Removed Local commands from lib/silccore/silccommand.h as
4591 they are application specific and new client library does not
4592 handle any of those anymore.
4594 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4595 old client implementation in silc/.
4597 * Added support for callback functions in SILC_LOG_* macros.
4598 Application can now set its own callbacks that will be called
4599 instead of using the default functions that will always print
4600 the debug messages to stderr (or stdout). Also, debugging can
4601 now be disabled by setting silc_debug to FALSE and re-enabled by
4602 setting it to TRUE. Note, that logging will still work even
4603 if debugging is disabled.
4605 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4606 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4607 silc_log_reset_debug_callbacks.
4609 * To enable debugging in silc client one must give now -d
4610 option on command line.
4612 * Changed silc_schedule_init to automatically allocate task queues
4613 if they are not allocated before calling it.
4615 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added GMP 3.1 into math library.
4619 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4622 a channel in SILC network. The packet is used by servers and
4623 routers to notify other routers that user has left a channel.
4624 This little feature was missing until now. Added the feature
4625 to protocol specification as well.
4627 Added functions: silc_server_send_remove_channel_user and
4628 silc_server_remove_channel_user into server.[ch].
4630 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4631 lib/silccore/silcpacket.h. However, they are not implemented
4634 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Fixed joining to a channel and sending channel messages
4637 between server and router. The channel message sending should
4638 now work inside a cell.
4640 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Fixed the private message sending between server and router.
4643 The private message sending should now work inside a cell.
4645 * Added silc_server_replace_id into server.[ch] to replace
4646 existing ID in the SILC network.
4648 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4649 and silc_idlist_replace_server_id into idlist.[ch] in server.
4651 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4653 * Fixed the server to server connections. Server can again now
4654 connect to router. Router to router connections probably does
4657 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added dynamic protocol registering support. Now protocols can
4660 registered and unregistered on the fly. Patch by cras.
4662 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Added lib/contrib directory to hold routines that some platforms
4665 don't have but are needed by SILC.
4667 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4668 into lin/contrib to provide getopt() and getopt_long() for
4669 those who don't have it.
4671 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Added AWAY command to client. When away message is set and
4674 client receives a private message packet the client automatically
4675 replies to the sender with the away message.
4677 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4678 bug seemed to be the cause of recent problems when compiling
4681 * Added version detection support to SKE protocol specification
4682 and added the new changes to the SKE implementation as well.
4683 There were other minor changes in the SKE protocol as well.
4685 Many changes in lib/silcske/silcske.[ch] and in
4686 lib/silcske/payload.[ch].
4688 * Added ^U functionality, clear input line. Patch from cras.
4690 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Mainly small bugfixes on core library. Fixed some debugging
4693 logging and buffer overflow in silclog.c.
4695 * Updated config.sub and config.guess on the distribution tree.
4697 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Added command lagging support in server. Client may execute
4700 commands now only once in two seconds.
4702 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Optimized packet reception. MAC computation and checking is now
4705 also more optimized. A lot previously duplicated code is now
4706 used as generic by both client and server.
4708 * Fixed key pair generation in clientutil.c
4710 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added into lib/silccore/silcbufutil.[ch] new function;
4713 silc_buffer_realloc.
4715 * Moved generic packet sending/encryption functions to
4716 lib/silccore/silcpacket.[ch] from client and server. Some
4717 rewriting of the functions.
4719 * Moved all generic packet reception/decryption functions to
4720 lib/silccore/silcpacket.[ch] from client and server. The
4721 packet processing is now much cleaner in both client and server.
4722 These were major changes in both client and server.
4724 * Created many common functions in server to do packet sending.
4725 Previously code were duplicated a lot, this has been removed
4728 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Rewrote major parts of the ID cache system. Don't know
4731 whether it is better now or not but at least the API is more
4734 * Major rewrite on ID cache stuff on client because of the ID
4735 cache API changes. Added idlist.c to client.
4737 * Also major rewrite on ID cache stuff on server as well.
4738 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4739 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4740 in hand, instead they are all put into the ID cache system now.
4741 All server_idlist_* routines uses ID cache now instead of
4742 traversing its own lists (those lists does not exist anymore).
4743 SilcIDList though still exists. Also, SilcXXXEntry's are
4746 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Finally made the SKE implementation compliant to the protocol
4749 specification. All mp integers are now binary encoded as
4750 opposed being HEX encoded.
4752 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4755 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4756 functions: silc_[encode/decode]_pem. Also added function
4757 silc_encode_pem_file to PEM encode with newlines ('\n') for
4760 * SILC public keys are now encoded either PEM or binary. Same
4761 option is for private keys as well. By default private keys
4762 are binary encoded and public keys PEM encoded. Silly HEX
4763 encoding were removed.
4765 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4766 function to create fingerprints.
4768 * Fixed a bug in SHA1; does not change the original data anymore.
4770 * Partly implemented INFO command on client and server side.
4771 Fixed CLEAR command. Changes to SERVER command; show current
4772 server(s) when giving command without arguments. Added
4773 VERSION command to client.
4775 * Added check to server that unregistered connections cannot
4776 execute commands (unless it is specificly allowed).
4778 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Fixed screen refresh.
4782 * Fixed channel joining bug from client. On some circumstances
4783 client tried to join to a channel it had already joined.
4785 * Added public key verification process into client's protocol.c.
4786 The client now verifies the public key from user and saves
4787 it into ~./silc/serverkeys/ directory.
4789 Added into: clientutil.[ch]: silc_client_verify_server_key.
4791 * Changed SKE protocol's silc_ske_initiator_finish function
4792 to accept callback function that verifies the received public
4793 key. Removed old silc_ske_verify_public_key function.
4795 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4798 silc_pkcs_private_key[_data]_set.
4800 * Made the password and public authentication more cleaner in
4801 server's protocol.c.
4803 * Removed historic and obsolete protocol `channel_auth' from
4804 both client and server.
4806 * Removed wrong way of sending command status messages from
4807 server to client in server's command.c. The old way violated
4808 protocol specification.
4810 Changes to silccore/silccommand.[ch]: removed
4811 silc_command_encode_status_payload -> not needed anymore,
4812 changed silc_command_encode_payload_va to accept extra
4813 argument on variable argument list. The argument type must
4814 now be provided to the function. Also, added new function:
4815 silc_command_encode_reply_payload_va which is same as
4816 normal command_encode_payload_va except command status type
4817 is provided as extra argument.
4819 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Added ~./silc directory handling. The directory includes the
4822 public and private keys for the client.
4824 Added silc_client_check_silc_dir, silc_client_create_identifier
4825 and silc_client_load_keys.
4827 * Implemented SILC protocol compliant public key. Added public
4828 and private key saving to and loading from files.
4830 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4831 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4832 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4833 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4834 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4836 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4837 silc_pkcs_load_[public/private]_key.
4839 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Added silc_server_get_route (route.[ch]) to get connection
4842 data for the fastest route for given ID.
4844 * Implemented INVITE command on client and server. The command
4845 were re-defined in the SILC Protocol Specification and the
4846 implementation now complies with the specification.
4848 * Implemented PING command on client and server.
4850 * Implemented NAMES command on client and server. The server side
4851 supports currently only normal server not router server yet.
4852 Some changes to NAMES definition in SILC protocol specification.
4854 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Implemented LEAVE command on client and server.
4858 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4859 again. This change was made to the protocol as well. Server
4860 should not violate the protocol specification anymore.
4862 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4865 was tested. SOCKS4 was not but should work anyway.
