1 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Do not cancel the protocol in silc_server_close_connection
4 it might cause recursion. Now cancelled in the function
5 silc_server_free_sock_user_data. Affected file silcd/server.c.
7 * Fixed the silc_server_remove_clients_by_server to regenerate
8 the channel keys correctly finally. Added also new function
9 silc_server_remove_clients_channels to actually do it.
10 Affected file silcd/server.c.
12 * Fixed the silc_server_new_channel to not crash by giving
13 wrong router to the new channel. Affected file is
14 silcd/packet_receive.c.
16 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
18 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
19 which is given as argument to the silc_client_alloc now.
20 It can be used to configure the client and set various parameters
21 that affect the function of the client.
23 * The USERS command in server did not check whether the channel
24 is private or secret. Affected file silcd/command.c.
26 * Added new argument to the USERS command in protocol specification.
27 The USERS command now can take the channel name as argument
28 as well. Added support for this in client and server and
29 updated the protocol specs.
31 * Completed the GETKEY command in client. It can be now used
32 to fetch also servers public key not only some clients.
33 Affected files lib/silcclient/command[_reply].c.
35 * Added silc_client_get_server to return server entry by the
36 server name. Affected files lib/silcclient/silcapi.h and
39 * Redefined the IDENTIFY command in protocol specification to be
40 more generic. It now can be used to query information about
41 any entity in the SILC Network, including clients, servers and
42 channels. The query may be based either the entity's name
43 or the ID. Added support for this in both client and server.
45 Affected files silcd/command.c and lib/silcclient/command.c
48 * Optimized the WHOIS and WHOWAS commands in the server. Removed
49 the _from_client and _from_server functions. Affected file
52 * Added silc_client_get_channel_by_id_resolve to the file
53 lib/silcclient/silcapi.h to resolve channel information by
54 its ID. Added also silc_client_get_channel_by_id that
55 does not resolve it from the server.
57 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
59 * Added SilcServerEntry context into the client library
60 to represent one server. The INFO command now allocates
61 these to save the resolved server info. For now on the
62 client library will also keep information about servers,
63 connected and resolved with INFO.
65 The INFO command now allocates the SilcServerEntry context
66 and saves the server info there. The COMMAND_REPLY in
67 the INFO now returns the parameters to application in
68 same order as defined in the protocol specification.
70 The entries are cached in the client->server_cache.
72 * The INFO command is now issued after received the Client ID
73 from the server. Affected file lib/silcclient/client.c.
75 * The CMODE_CHANGE notify may now return also an SilcServerEntry
76 to the application as the mode changer might be server.
77 It is guaranteed that NULL is not returned anymore to the
78 application. Affected file lib/silcclient/client_notify.c.
80 The ID Type is now also passed to the application so that
81 it can check whether the returned entry is SilcClientEntry
84 Added new function silc_client_get_server_by_id to return
85 the server entry by ID. Affected files are the
86 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
88 * Do not create the channel in the Irssi SILC Client when issuing
89 the JOIN command but when received the sucessful JOIN command
90 reply. Otherwise the channel might get created even though we
91 could not join it. The Affected file is
92 irssi/src/silc/core/[silc-channels.c/client_ops.c].
94 * Fixed a channel joining bug in router. The router must also
95 check the channel modes, invite and ban lists etc. when serving
96 the JOIN command sent by normal server. Affected file is
97 silcd/command.c. The router now resolves the client's
98 information from the server who sent the JOIN command if it
99 does not know it, and processes the JOIN command only after
102 * Changed the SilcCommandCb to take new argument; void *context2.
103 Affected file lib/silccore/silccommand.h
105 The second argument in the command callbacks in the server now
106 includes the SilcServerCommandReplyContext if the command was
107 called as pending command callback from the command reply.
108 Otherwise it is NULL. When called as pending the status of the
109 command reply will be checked and if it was erronous the
110 error will be sent to the original sender of the command.
111 This way the client always receives the error messages even
112 though the server was actually the one who received the error
113 when it resent the command to router, for example. Affected
114 files silcd/command[_reply].[ch].
116 * Fixed sending WHOWAS command's error message to client if
117 the requested client could not be found. It was missing.
120 * Changed the CMODE and CUMODE commands reply arguments in the
121 protocol specification. The Channel ID is now sent in both
122 of the commands to identify the channel. Implemented this
123 new feature to the client and server. Affected files
124 lib/silcclient/command_reply.c and silcd/command.c.
126 * Made better checks for invite and ban lists in the JOIN
127 command in server. Affected file silcd/command.c.
129 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
131 * The server now performs the incoming host IP/DNS lookup
132 using the silc_socket_host_lookup and thus does not block
133 the server anymore. Affected file silcd/server.c.
135 * Completed the multi-thread support for SILC Scheduler in
136 the lib/silcutil/silcschedule.c.
138 * Fixed the configure.in.pre to detect the pthread correctly
141 * Fixed a deadlock in silc_task_queue_wakeup in the file
142 lib/silcutil/silctask.c.
144 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
146 * Added new function silc_schedule_wakeup that is used in
147 multi-threaded environment to wakeup the main thread's
148 schduler. It needs to be used when a thread adds a new task
149 or removes a task from task queues. After waking up, the
150 scheduler will detect the task queue changes. If threads
151 support is not compiled in this function has no effect.
152 Implemented the wakeup mechanism to both Unix and WIN32
153 systems. Affected files are lib/silcutil/silcschedule.[ch],
154 lib/silcutil/unix/silcunixschedule.c and the
155 lib/silcutil/win32/silcwin32schedule.c.
157 * Added new function silc_task_queue_wakeup to wakeup the
158 scheduler by the specified task queue. Affected file
159 lib/silcutil/silctask.[ch].
161 * The silc_socket_host_lookup_start now wakes up the scheduler
162 after adding the timeout task. Affected file is
163 lib/silcutil/silcsockconn.c.
165 * The silc_socket_host_lookup is synchronous now if the threads
166 support is not compiled in. However, the callback is still
167 called asyncronously through the scheduler, anyway. Affected
168 file lib/silcutil/silcsockconn.c.
170 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
172 * Added new function silc_socket_host_lookup to perform
173 asynchronous IP and FQDN lookups for the socket connection.
174 Affected files lib/silcutil/silcsockconn.[ch].
176 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
178 * Added SILC_MUTEX_DEFINE to define the mutex on environments
179 that may or may not compile the mutex support in.
181 Changed the silc_mutex_alloc interface. It allocates the
182 mutex now to the sent pointer and returns TRUE or FALSE.
184 Affected file lib/silcutil/silcmutex.h.
186 * Wrote the SILC Task Queue interface to support multi-threads.
187 Affected file lib/silcutil/silctask.[ch].
189 * Wrote the SILC Scheduler to support multi-threads. Affected
190 file lib/silcutil/silcschedule.c.
192 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
194 * Implemented the SILC Mutex API and SILC Thread API for WIN32
195 in lib/silcutil/win32/.
197 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
199 * Defined SILC Mutex API and SILC Thread API and implemented
200 them for Unix. Affected files are
201 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
202 lib/silcutil/unix/silcunixmutex.c and
203 lib/silcutil/unix/silcunixthread.c.
205 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
207 * Fixed the silc_server_remove_clients_by_server's channel
208 key re-generation. The hash table handling was incorrect
209 and would not work with many channels. Affected file is
212 * Fixed some memory leaks around the server code.
214 * Rewrote the silc_server_get_users_on_channel to support IPv6
215 based Client ID's. Affected file silcd/server.c.
217 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
218 specification. However, a separate document must be written
219 to define the detailed signing procedure and the payload
220 associated with the flag. Defined the flag to the
221 lib/silccore/silcchannel.h as well.
223 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
225 * Changed the dynamic tables to static size tables in the
226 lib/silccrypt/silchmac.c.
228 * Removed GCC dependencies from the code. A patch by cras.
230 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
232 * Do not show the error "Error receiving packet bla bla"
233 in server if it really was not an error (-2 means that reading
234 is pending). Affected file silcd/server.c.
236 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
238 * Fixed a possible crash in silc_server_remove_clients_by_server
239 in silcd/server.c. Fixed there also some memory leaks.
241 * Fixed the silc_idlist_replace_client_id. It could replace
242 wrong key in the hash table. Affected file silcd/idlist.c.
244 * Do not check whether there are global users on the channel
245 if the channel->global_users is FALSE. Affected functions
246 silc_server_remove_from_one_channel and
247 silc_server_remove_from_channels in silcd/server.c. Also,
248 do not check if the removed client is local as we can be
249 sure that global client was not removed from the channel
250 and checking for global users is not needed.
252 * The silc_server_remove_clients_by_server now re-generates
253 the channel keys correctly for those channels that had
254 clients removed from them. Affected file silcd/server.c.
256 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
258 * Found the reason of random crashes in the server. We weren't
259 ignoring the SIGPIPE signal (which can be sent in write())
260 and it crashed the server. Affected file silcd/silcd.c.
262 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
264 * Assure that sock->user_data is not NULL in the function
265 silc_server_packet_send in silcd/packet_send.c.
267 * Disconnect the remote connection if it could not be added
268 to any ID lists in the server. The affected file is
271 * Check in silc_server_packet_send[_real/dest] that the
272 socket is not disconnecting and ignore the data if it is.
273 Affected file silcd/packet_send.c.
275 * Define inline to __inline on native WIN32 compilation.
276 Affected file includes/silcwin32.h.
278 * Added some explicit type casts for inline code since MSVC
279 require them. Affected files lib/silcutil/silcbuffer.h,
280 lib/trq/silcdlist.h and lib/trq/silclist.h.
282 * Print warning in log files from now on if the packet
283 decryption fails. Affected file silcd/server.c.
285 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
287 * Changed the `say' client operation's interface to accept
288 new `type' argument to indicate the type of the message sent
289 by the library. The application may filter the library's
290 messages according the type. The affected file is the
291 lib/silcclient/silcapi.h.
293 * Added two new functions to lib/silcclient/silcapi.h:
294 silc_client_del_client and silc_client_del_client_by_id.
295 Affected file lib/silcclient/idlist.c.
297 * Moved the clientincludes.h from includes/ to silc/ and
298 serverincludes.h from includes/ to silcd/.
300 * The modes for the CMODE and CUMODE are now passed as
301 uint32 for application with COMMAND_REPLY. The affected
302 file is lib/silcclient/command_reply.c.
304 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
306 * /WHOIS without arguments shows client's own information.
307 Affected file lib/silcclient/command.c.
309 * Changed PING to not accept any arguments. The specs
310 says that client can ping only the connected server so
311 requiring an argument is not needed. Affected file is
312 lib/silcclient/command.c.
314 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
316 * Fixed a fatal bug in private message sending and reception
317 encryption and decryption when using private message keys.
318 The implementation was incorrect and did not follow the
319 specification. It causd that some of the message were
320 lost since it did not use the sending and receiving keys
321 as the protocol suggests. This has been fixed and will cause
322 incompatibilities with older clients when sending private
323 message encrypted with private message keys. Affected files
324 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
325 and various other in Irssi SILC Client.
327 Added `responder' boolean argument to the functions
328 silc_client_add_private_message_key[_ske] to indicate when
329 the key is added as responder or initiator of the key
332 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
334 * Removed the silc_ske_check_version function and created
335 a SilcSKECheckVersion callback. Added also a function
336 silc_ske_set_callbacks that is now used to set all SKE
337 callbacks. The callback functions are not given to
338 the SKE functions anymore, but this function is used to
341 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
343 * Added `silc_version' argument to the silc_client_alloc
344 to define the version of the application for the library.
345 The library will use the version string to compare it
346 against the remote host's (usually a server) version
347 string. Affected file lib/silcclient/silcapi.h
349 * Added the KE protocol context to Key Agreement context
350 in client library so that we can abort the SKE if it
351 is in process when we get timeout. Affected file is
352 lib/silcclient/client_keyagr.c.
354 * Do not resolve the client ID forever if it returns in the
355 first time that such client does not exist. This was done
356 for example with private message. Affected file is
357 lib/silcclient/client_prvmsg.c.
359 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
361 * Do not add regex.h for WIN32. The affected file
362 includes/silcincludes.h.
364 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
365 not work yet 100%. It generates the DLL's automatically
366 when compiling with --with-win32 under cygwin.
368 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
370 * lib/contrib/regex.c is not compiled on WIN32.
372 * Added silc_net_get_socket_opt function to the
373 lib/silcutil/silcnet.h.
375 * Added includes/silcwin32.h for WIN32 specific includes
378 * Do not use ptime structure or any of the posix process
379 functions on WIN32 in lib/silccrypt/silrng.c.
381 * Added silc_gettimeofday to provide generic function
382 for struct timeval on all platforms. Added the function
383 to lib/silcutil/silcutil.h.
385 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
387 * Moved the lib/silccore/silcsockconn.[ch] to the utility
388 library as they clearly belong there. As a plus side we
389 can make the actual socket connection routines platform
392 Added also new generic function silc_socket_read and
393 silc_socket_write (that used to be silc_packet_[read/write].
394 The implementation of these are platform specific.
396 * Added WIN32 specific routines of silc_socket_[read/write]
397 to lib/silcutil/win32/silcwin32sockconn.c.
399 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
401 * Added preliminary support for native WIN32 compilation under
402 cygwin (using the -mno-cygwin option for GCC) to the
403 ./configure.in.pre. The --with-win32 now prepares the
404 compilation for native WIN32.
406 * Rewrote the SILC Scheduler interface in the file
407 lib/silcutil/silcschedule.h. The scheduler is now context
408 based and does not have anymore any global static scheduler.
409 Moved the Unix scheduler to the lib/silcutil/unix/ directory
410 and created lib/silcutil/win32 directory for WIN32 based
413 * Added Unix specific network routines to the
414 lib/silcutil/unix/silcunixnet.c and the old
415 lib/silcutil/silcnet.c includes now only generic routines.
417 Added WIN32 specific network routines to the
418 lib/silcutil/win32/silcwin32net.c.
420 * Added Unix specific utility functions from the
421 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
423 * Added WIN32 SILC Scheduler to the file
424 lib/silcutil/win32/silcwin32schedule.c. The code is of course
427 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Do not handle JOIN notify in the server if the target client
430 is not registered (idata->registered == FALSE). The affected
431 file is silcd/packet_receive.c.
433 * Update the nickrec->founder in event_cumode in the Irssi SILC
434 client. Affected file irssi/src/silc/core/silc-channels.c.
436 * Fixed the CUMODE_CHANGE notify handling in the server when
437 server and router are announcing their clients on channels.
438 Now the mode changes are saved and notified correctly. The
439 affected file is /silcd/packet_receive.c.
441 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
442 They really did not replace the cache entry in the ID Cache.
443 Now they do that. Affected file silcd/idlist.c.
445 * Fixed the KICK notify handling in the Irssi SILC client to
446 update the channel records so that the kicked client does not
447 appear to be on the channel. The affected file is
448 irssi/src/silc/core/silc-channels.c.
450 * Always update the conn->current_channel when executing command
451 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
453 * Fixed the KILL notify handling in Irssi SILC client to remove
454 the killed client on all channels.
456 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * Fixed the silc_parse_command_line to remove extra spaces
459 from the start and end of the arguments. Affected file is
460 lib/silcutil/silcutil.c.
462 * Cancel and free any active protocol in the function
463 silc_server_close_connection. Affected file silcd/server.c.
465 * Cancel and free any active protocol in the function
466 silc_client_close_connction. Affected file is
467 lib/silcclient/client.c.
469 * Do not execute the KILL command for clients that are in
470 history (ie. they are not in the network). Affected file is
473 * Fixed KILL notify handling, client does not crash anymore.
474 Affected file irssi/src/silc/core/silc-channels.c.
476 * Reduced the default packet buffer size from 2048 to 1024 in
477 lib/silccore/silcpacket.c.
479 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
480 counter to the SKE context that is incresed when the SKE library
481 performs async operation outside the library. If the outside
482 process frees the SKE context and FREED status will be set
483 and the library will detect after the sync operation that the
484 libary is freed. The affected files are
485 lib/silcske/silcske[_status].[ch].
487 * Resolve the client entry information in the function
488 silc_client_channel_message to assure that NULL pointer is not
489 passed as client entry to the application. */
491 * Fixed the task timeout calculation to assure that there is
492 never negative timeouts. The affected file is
493 lib/silcutil/silcschedule.c.
495 * Fixed the channel user mode notification sending in server.
496 It was sent point-to-point to the router (or to server by router)
497 but it needs to be destined to a channel. The routines now
498 supports sending the channel user mode notifys to the channels
499 when announcing clients and channels. Affected files are
500 silcd/server.c and silcd/packet_receive.c.
502 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
503 It did not actually replace the old channel entry in the cache.
504 Affected file lib/silcclient/client_notify.c.
506 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Fixed a possible crash in silc_packet_send_prepare. It now
509 assures always that there is enough space in the buffer and
510 at the tail area of the buffer (for MAC).
512 Fixed the inbound buffer reallocation in silc_packet_read.
513 It was old code and did not handle the reallocation correctly.
516 The affected file is lib/silccore/silcpacket.c.
518 * Fixed buffer overflow in silc_parse_nickname in the file
519 lib/silcutil/silcutil.c.
521 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * make install generates new server keys only if there is not
526 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
529 Added check that if the NOREPLY is set then we will not send
530 the away message. This avoids infinite loop of away messages
531 if both clients are away. The affected file is
532 lib/silcclient/client_prvmsg.c.
534 * Fixed client crash if /NICK was given without arguments.
535 Affected file lib/silcclient/command.c.
537 * Server does not send the invite list in INVITE command back
538 to the client if the list was not altered. Added this notion
539 to the protocol spec as well. Affected file silcd/command.c.
541 Fixed possible crash in INVITE command by checking the
542 value of silc_server_get_client_route command.
544 * Fixed the INVITE notify type handling. The arguments are now
545 taken in correct order and client does not crash. The affected
546 file is irssi/src/silc/core/silc-channels.c.
548 Removed the "Inviting xxx to channel" message from the
549 client library away and let the application handle it.
550 Affected file lib/silcclient/command.c. Added that message
551 to Irssi SILC client's message formats.
553 * Fixed CMODE command crash in client. It now checks the
554 amount of arguments correctly and does not crash. The affected
555 file is lib/silcclient/command.c.
557 * Do not create new channel automatically in silc_channels_join
558 but check whether the channel by that name already exists.
559 Affected file irssi/silc/core/silc-channels.c.
561 * Do not send the SERVER_SIGNOFF to router if the disconnected
562 entity was the router. Affected file silcd/server.c.
564 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
565 SILC client as it was missing from there.
567 Added the handling of the KICK notify to the Irssi SILC client
568 as it was missing. Added "you have been kicked" message to
569 Irssi SILC client's message modules formats.
571 Added the handing of the KILL notify to the Irssi SILC client
572 as it was missing. Added the kill message module formats
575 The affected file is irssi/src/silc/core/silc-channels.c.
577 * The router did not save the channel mode the server announced.
578 Affected file silcd/packet_receive.c.
580 * Fixed a possible crash in INFO command in server. If the
581 server did not provide the server info it crashed. Affected
582 file silcd/command.c.
584 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Fixed the GETKEY command in the server to check also the
587 global list. Otherwise the GETKEY would not work correctly
588 in normal SILC server. Affected file silcd/command.c.
590 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Fixed GETKEY crash, it crashed if the command did not succseed.
594 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
597 is now real and not just an macro interface to GMP.
599 Removed the entire GMP from the source tree and imported new
600 NSS MPI library instead. Reason for removing GMP is that it is
601 extremely large and compiles extremely slow. The NSS MPI
602 is only a few files and compiles in less than 10 seconds.
603 The speed is also about the same as GMP. The MPI is imported
606 If the system has GMP installed we will still use the GMP.
607 If it is not then the NSS MPI will be compiled.
609 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Merged a long nickname (127 characters long) crash bugfix from
612 Irssi CVS tree. Affected file irssi/src/core/misc.c.
614 * Merged a freed memory reference bugfix from Irssi CVS tree.
615 Affected file irssi/src/core/commands.c.
617 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Added the server's public key sving and verification to the
620 server when performing the SKE. This was missing and the
621 remote server's (or router's) public key was accepted without
622 checking whether we have it previously or trust it at all.
623 Affected file silcd/protocol.c.
625 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * Check in the silc_server_timeout_remote if protocol is active
628 and make sure that the protocol's final callback is called so
629 that all memory if freed. Affected file silcd/server.c.
631 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * silc_server_whois_send_reply crashed the server if the nickname
634 was 127 characters long. Affected file silcd/command.c.
636 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Added sanity check to the silc_server_new_client. If the hostname
639 is provided inside username then check that the provided hostname
640 really is the same as the resolved one. If the hostname was not
641 resolved then check it from the public key. Affected file is
642 silcd/packet_receive.c.
644 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
645 if the server disconnected us and the connection is not valid
646 anymore. Affected file irssi/src/silc/core/silc-channels.c.
648 * Moved the silc_client_[chmode|chumode|chumode_char] away from
649 the library to the lib/silcutil/silcutil.[ch].
651 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * Close log file after open. Affected file
654 lib/silcutil/silclog.c.
656 * Check whether sock == NULL in silc_client_send_packet and return
657 if it is. Affected file lib/silcclient/silcclient.c.
659 * Check rec->entry == NULL in the Irssi SILC Client before
660 sending the channel message. Affecte file is
661 irssi/src/silc/core/silc-servers.c.
663 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Merged a splitted window bugfix from Irssi CVS tree. The
666 affected file is irssi/src/fe-text/textbuffer-view.c.
668 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
669 It did not print nickname.
671 * Improved the distributions system a bit.
673 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
676 irssi/src/fe-text/gui-window.c.
678 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
679 to in-active server. The affected file is
680 irssi/src/silc/core/client_ops.c.
682 * Resolve the client in USERS command reply if the entry does
683 not have username resolved. The affected file is
684 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
685 command to WHOIS command to really resolve stuff. The USERS
686 is not used any more in any critical section so WHOIS can
687 be used even though it might be slower than IDENTIFY.
689 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
692 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Changed the protocol API a bit more consistent in the
695 lib/silccore/silcprotocol.[ch].
697 * Changed the following headers to ROBODoc format:
699 lib/silccore/silcpayload.h
700 lib/silccore/silcprotocol.h
701 lib/silccore/silcsockconn.h
703 All core library headers are now formatted.
705 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Fixed a bug in Irssi SILC client; do not show that you are
708 server/router operator if you really are not. Affected file is
709 irssi/src/silc/core/client_ops.c.
711 * Renamed silc_command_free_payload to silc_command_payload_free.
712 Affected file lib/silccore/silccommand.h
714 * Added silcmath.h to include the prototoypes of various routines
715 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
718 * Changed the following headers to ROBODoc format:
720 lib/silccore/silcchannel.h
721 lib/silccore/silccommand.h
722 lib/silccore/silcid.h
723 lib/silccore/silcidcache.h
724 lib/silccore/silcmode.h
725 lib/silccore/silcnotify.h
726 lib/silccore/silcpacket.h
727 lib/silcmath/silcmath.h
729 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Added checking to the server code not to start the server if
732 ciphers and stuff are not configured properly. Affected files
733 silcd/serverconfig.[h] and silcd/server.c.
735 * Changed the layout of the header files of the public interfaces
736 in the SILC libraries. The new layout supports ROBODoc
737 documentation tool (and some others) so that it is easy to create
738 a library reference manual. All the other headers and source
739 code must still follow the CodingStyle document. Also source
740 code must not include these ROBODoc stuffs, only the headers.
741 Furthermore, all public interface headers must now be named
742 by using `silc' prefix, example: silcapi.h, silccipher.h.
743 Some files were renamed due to this. All the other headers
744 must not be used as public interfaces. I will update the
745 CodingStyle document later. Changed following headers, so far:
747 lib/silcclient/silcapi.h
748 lib/silccore/silcauth.h
749 lib/silccore/silcprivate.h
750 lib/silccrypt/silcdh.h
752 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Removed silc_client_packet_send_flush from the client library
757 as it is not needed. Affected file lib/silcclient/client.[ch].
759 * Added printing of message of unresolved authentication method
760 to the Irssi SILC client. Added it to the module formats.
761 Removed the same message from the client library.
763 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
765 * Added new distribution feature, DISTLABEL. Every distribution
766 can define own preprocessor label that can be used in the
767 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
768 file distributions, acconfig.h.pre and prepare.
770 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Added Makefile.defines_int to include the actual definitions
773 for Makefile.defines.in. Tested the new distribution system,
774 created distributions and tested installation.
776 * Added AWAY message printing to the Irssi SILC client. Added
777 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
779 * Added SCONNECT command to call the SILC's CONNECT command.
780 Cannot use CONNECT directly since Irssi uses that internally.
781 Affected file irssi/src/silc/core/silc-servers.c.
783 Added ACTION local command. It is same as ME command but takes
784 the channel as mandatory argument.
786 Rewrote some of the Irssi's help files to suite for SILC
789 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Added Makefile.defines[.in] that should for now on be included
792 in all Makefile.am file in the source tree. That file includes
793 all common compilation definitions for SILC source tree.
795 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Minor changes to the ./prepare script to change the package
798 name according the distribution name to the configure.in.
800 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
802 * Created new distribution system. Added file `distributions'
803 that defines all the distributions that can be created out of
804 the SILC source tree. The ./prepare script now reads that
805 file to determine how to prepare the distributions. The
806 first argument to the ./prepare is the name of the distribution
807 and second is the version of the distribution. If given
808 without arguments it creates the default (toolkit) distribution
809 with the default version (defined in ./prepare).
811 All Makefile.am files that are subject to the distributions
812 are now named as Makefile.am.pre. These are ./Makefile.am
813 and lib/Makefile.am. Others may be changed later.
815 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Added invite list, ban list, some key management and connection
818 error message printing to module formats in the Irssi SILC client.
820 * Added new silc_client_set_away_message to set the away message
821 that is back to the person who sent private message. The
822 affected file lib/silcclient/silcapi.h and the
823 lib/silcclient/client_prvmsg.c.
825 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Fixed the private message sending in the Irssi SILC client,
828 added local command KEY to the Irssi SILC client.
830 Added key management and key agreement message formats to the
831 irssi/src/fe-common/silc/module-formats.[ch].
833 Added USERS (alias WHO) printing, server/router operator
834 indication and LIST command printing to the module formats.
836 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Fixed channel joining notify handling, cumode notify handling
839 from Irssi SILC client.
841 * Added SILC specific module-formats to the Irssi SILC client so
842 that SILC specific message hilighting, colors etc is possible.
843 Affected file irssi/src/fe-common/silc/module-formats.[ch].
845 Added channel mode, channel user mode, actions, notices,
846 whois and whowas printing to the the module-formats.c.
848 * Fixed a bug in channel deletion in the server. The channel
849 is not left to the cache even if the channel founder auth mode
850 is set when there are no users anymore on the channel. Affected
853 * The silc_net_localhost now resolves the entire hostname including
854 the domain name. Affected file lib/silcutil/silcnet.c.
856 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Changed the ask_passphrase client operation to be ascynchronous.
859 It has now a completion callback and a context that the
860 application must call after it has got the passphrase from
861 the user. Affected files lib/silcclient/silcapi.h,
862 lib/silcclient/protocol.c, lib/silcclient/command.c and
865 Added SilcAskPassphrase callback that the application calls
866 to deliver the passphrase to the library.
868 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
869 The public key verification and especially a certificate
870 verification is asynchronous procedure.
872 Added new SILC_SKE_STATUS_PENDING status to indicate the
873 request is pending and a callback will be called to finalize
876 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
877 indicate that remote end did not send its public key (or
878 certificate), even though we require it. Added check for this
879 condition in the SKE. This was a security bug, now fixed.
881 Defined new SilcSKEVerifyCbCompletion callback that is called
882 when the verification process is completed.
884 The affected files lib/silcske/silcske_status.h and
885 lib/silcske/silcske.[ch].
887 * Changed the verify_public_key client operation to be async
888 as well. Defined SilcVerifyPublicKey callback that is used to
889 indicate the success of the public key verification process.
891 Changed the server and client to use the new async client
894 * Changed the Irssi SILC client's internal scheduler to be called
895 twice as many times as it used to be. As a result the client
896 should be a bit faster now. Affected file is
897 irssi/src/silc/core/silc-core.c.
899 * Added support to Irssi SILC client of asynchronous public key
900 verification and passphrase inquiry. Affected file is
901 irssi/src/silc/core/silc-core.c.
903 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Do not say "You have left channel %s" in client library.
906 Moved it to the application. Affected files are
907 lib/silcclient/command.c and silc/client_ops.c.
909 * Fixed silc_client_get_clients. Command context was not
910 duplicated and was freed memory in the callback. Affected
911 file lib/silcclient/idlist.c.
913 * Do not say "you are now talking..." on JOIN command in the
914 client library. The appliation must handle it.
916 * Do not say ".. changed topic to" in command reply in the
917 client libary. The application must handle it.
919 * Fixed TOPIC command sending in the client library.
921 * Fixed a memory leak in silc_client_command_free in the file
922 lib/silcclient/command.c.
924 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Imported a modified version of Irssi client to the source tree.
927 The Irssi will be used to create a new client called
928 Irssi SILC. Imported to irssi/.
930 Added silc_core_init_finish function to the Irssi. Affected
931 file irssi/configure.in.
933 A lot changes in the Makefile.ams around the irssi tree.
935 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Do not rehash if the new size is same as the old size of the
938 hash table, in the silc_hash_table_rehash*. The affected file
939 lib/silcutil/silchashtable.c.
941 * Replaced hash_table_del_by_context calls from the server
942 (when channel->user_list and client->channels) to the
943 hash_table_del as it is sufficient and faster.
945 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
947 * Added silc_hash_table_list, silc_hash_table_get and the
948 SilcHashTableList structure to provide an alternative way to
949 traverse the hash table. The affected files are
950 lib/silcutil/silchashtable.[ch].
952 * Changed the server's idlist routines to use the hash table
953 routines to optimize the code.
955 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
957 * Replaced the client entry's `channel' list and channel entry's
958 `user_list' list to hash tables for optimized lookup. Changed
959 the code to use the hash table interface around the code.
960 Affected file lib/silcd/idlist.[ch].
962 * Added `auto_rehash' boolean argument to the function
963 silc_hash_table_alloc to indicate whether the hash table should
964 auto-rehash when it thinks is appropriate time. It will
965 increase the hash table size if the there is twice as much
966 entries in the table than the size of the table, and will
967 decrease the size if there are twice as less entries than
968 the size of the table.
970 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Fixed silc_xxx_get_supported to not crash at some circumstances.
974 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * silc_idcache_purge_by_context deletes the entry now by context
977 as it is supposed to do. Affected file lib/silccore/idcache.c.
979 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
980 client is not anymore valid (WHOWAS givens the info) and not
981 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
983 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * Removed the `data' and `data_len' arguments from the ID Cache
986 interfaces and added `name' argument. ID Cache does not handle
987 anymore the binary data only a names associated with given ID.
989 * When hashing a Client ID with silc_hash_id the entire ID is
990 not hashed anymore, instead only the hash of the Client ID is
991 hashed. This way we can access the Client ID from the cache
992 with Client ID but with the hash of the ID (which is a hash of
993 the nickname) as well without any difference in performance.
995 Added also silc_idcache_find_by_id_one_ext to do one on one
996 searching when we have the actual ID. Added also function
997 silc_hash_client_id_compare. The affected files are
998 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1000 * When hashing the name associated with a ID it is always done
1001 in lowercase. This way we can access the cache without worrying
1002 about case-sensitivity, even though, for example nicknames are
1005 * Fixed a bug in server with channel message sending. It put
1006 wrong ID type as destination ID. The affected file
1007 silcd/packet_send.c.
1009 * silc_idcache_del_by_context now deletes from all hash tables
1010 by context. Affected file lib/silccore/idcache.c.
1012 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * Changed the client library to use the new ID Cache interface.
1015 Changes around the source tree.
1017 * Added silc_hash_table_rehash_ext to rehash with specific
1018 hash function. Affected file lib/silcutil/silchashtable.[ch].
1020 * Added silc_hash_string_compare to compare two strings in the
1021 hash table. Affected file lib/silcutil/silcutil.[ch].
1023 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Added new function silc_idcache_del_by_context into the
1026 lib/silccore/idcache.[ch].
1028 * Changed the server's ID list routines to use the new ID Cache
1029 interface. Changes around the source tree.
1031 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Added silc_hash_table_del[_by_context]_ext functions in to the
1034 lib/silcutil/silchashtable.[ch].
1036 Removed silc_hash_table_find_all* routines and added new
1037 silc_hash_table_find_foreach to replace them.
1039 Added silc_hash_table_replace_ext function as extended
1040 replacing function. Separated the simple hash table interface
1041 from the extended hash table interface in the file
1042 lib/silcutil/silchashtable.h.
1044 * Fixed minor bugs and changed it to use some of the new
1045 hash table functions in lib/silccore/idcache.c
1047 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Added new function silc_hash_table_find_all to return all keys
1050 in the hash table by the specified key. As the hash table is
1051 collision resistant it also makes it possible to have several
1052 duplicate keys in the hash table. This function may be used to
1053 find all of the keys from the hash.
1055 Added user_context arguments to the SilcHashFunction,
1056 SilcHashCompare and SilcHashDestructor to deliver user specified
1059 Added new fuctions silc_hash_table_find[_all]_ext to do
1060 extended lookup with specified hash and compare functions and
1061 specified user contexts.
1063 Added new function silc_hash_table_add_ext to add the key
1064 with specified hash function and user context.
1066 Added new function silc_hash_table_foreach to traverse all
1067 entrys in the hash table. Added SilcHashForeach callback
1070 Added new function silc_hash_table_del_by_context to delete
1071 the entry only if the context associated with the key matches.
1073 Affected files are lib/silcutil/silchashtable.[ch].
1075 * Removed silc_hash_[server/client/channel]_id and added just
1076 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1077 silc_hash_id_compare to compare two ID's using as the hash table
1078 comparison function. Added also silc_hash_data to hash
1079 binary data and silc_hash_data_compare to compare it.
1081 * Removed silc_idlist_find_client_by_hash as it is not needed
1082 anymore. Affected file silcd/idlist.[ch].
1084 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1085 to use internally the SilcHashTable. The new ID Cache is a lot
1086 faster than the old one. Some of the ID Cache interface was also
1087 rewritten and obsolete and stupid functions were removed.
1089 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Added entry_count field to the SilcHashTable to keep the number
1092 of the entries in the table. Implemented the function
1093 silc_hash_table_rehash. Added new function
1094 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1096 Fixed a minor bug in silc_hash_table_free.
1098 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1099 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1100 into the lib/silcutil/silcutil.[ch].
1102 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Implemented a collision resistant hash table into the
1105 lib/silcutil/silchashtable[ch]. See the header and the source
1106 for the SilcHashTable API.
1108 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Merged dotconf version 1.0.2 into lib/dotconf.
1112 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1114 * Do not compile anything in lib/silcsim/* if the SIM support
1115 is not enabled. The tree should now compile without problems
1118 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1120 * Compiled the SILC under cygwin. Compiled and tested briefly
1121 without problems. More tests needed. The SIMs didn't compile
1124 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1126 * Fixed possible crash in silc_get_username in the
1127 lib/silcutil/silcutil.c.
1129 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Fixed a va_arg in silc/client_ops.c.
1133 * Oops, RC5 routines were named AES and caused some problems
1134 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1136 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1138 * Added new SilcIDIP structure into the lib/silccore/id.h and
1139 replaced the old `ip' fields from all SILC ID's to that type.
1140 This is a step towards IPv6 support.
1142 The silc_id_get_len takes now the ID as an extra argument.
1143 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1144 both IPv4 and IPv6 based ID's.
1146 The affected files are lib/silccore/id.[ch] and other files
1147 around the tree using these routines.
1149 * Removed the ID length arguments in server from various
1150 silc_server_send_notify_* routines -> they are not needed
1153 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1155 * Fixed memory leak in silc_encode_pem_file in the file
1156 lib/silcutil/silcutil.c.
1158 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Check minor version as well in the SKE. Affected files are
1161 silcd/protocol.c and lib/silcclient/protocol.c.
1163 * Added --identifier option to the server so that an identifier
1164 can be when creating the public key for the server. Affected
1165 file is silcd/silcd.c.
1167 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1168 lib/silccrypt/silcpkcs.c.
1170 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Register default ciphers and stuff when using -C option with
1173 the server. Affected file sildc/silcd.c.
1175 * Put back the servers public key filename format, it is better
1176 than the new one. For now, the client keys are saved with the
1177 new filename format. The affected file silc/client_ops.c.
1179 * Implemented the Cipher API for the rest of the ciphers that
1180 did not implement it or implemented it the wrong way.
1182 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1184 * Register default ciphers and stuff when using the -S option
1185 in the client. Affected file silc/silc.c. Same also when
1186 creating new key pair with -C option.
1188 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Fixed the silc_verify_public_key client operation function to
1191 save the public keys differently. The fingerprint is now
1192 used as filename and not the hostname. This way also the
1193 client keys are saved uniquely and not with hostnames. The
1194 affected file is silc/client_ops.c.
1196 * Trimmed the silc_hash_fingerprint function to remove extra
1197 whitespaces from the end of the fingerprint. The affected
1198 file is lib/silccrypt/silchash.c.
1202 * Added silc_cipher_register_default function to register all
1203 default ciphers. It can be used when configuration files
1204 does not exist and the application does not want any specific
1205 ciphers in any specific order.
1207 The SilcDList is now used as silc_cipher_list dynamically
1208 allocated cipher list. Removed the static list all together
1209 and now all ciphers must be allocated to the dynamic list.
1210 The silc_cipher_alloc routine was changed to check only the
1213 All silc_cipher_* routines that used to return int returns
1216 The affected files lib/silccrypt/silccrypt.[ch].
1218 * The same thing was done to silc_hash_* as for silc_cipher_*
1219 routines. Affected files lib/silccrypt/silchash.[ch].
1221 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1222 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1223 Added also silc_pkcs_[un]register[_default] functions.
1224 Removed the data_context from the PKCS API.
1226 * Added silc_hmac_register_default function to register default
1227 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1228 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1229 to unregister all hmacs at once.
1231 * Register the default ciphers, hash functions, PKCSs and HMACs
1232 if client's configuration file does not exist. The affected
1235 * The client did not load the hash functions from the SIM
1236 modules at all. Added support for this. Affected file is
1237 silc/clientconfig.c.
1239 * When decoding public key with silc_pkcs_public_key_decode, check
1240 the supported algorithm only if PKCS are registered. Affected
1241 file lib/silccrypt/silcpkcs.c. The same was done with the
1242 silc_pkcs_private_key_decode.
1244 * Fixed the SILC List routines to keep the list always in order.
1245 It used to change the list's order when traversing the list but
1246 not it preserves the order. Affected file lib/trq/silclist.h.
1248 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Added the client library to use the SilcSocketConnection's
1251 reference counter (by silc_socket_dup) to prevent the bug that
1252 the socket object may be freed underneath async operation.
1254 * The name resolv library checking fixes in the configure.in.pre.
1257 * Created new version of the protocol drafts for future
1258 development. The -03 drafts are the ones that will be changed
1259 in the trunk now and the -02 will remain as they are.
1261 * Send list of CUMODE notifys to the router when announcing
1262 the channel users to the router. Affected file silcd/server.c.
1263 If the router receiving channel founder CUMODE for a channel
1264 that already has channel founder it will send CUMODE notify
1265 to the sender to remove the channel founder rights from the
1266 announced client. Affected file silcd/packet_receive.c.
1268 * The CUMODE notify may now use Server ID as well as the entity
1269 who changes the mode. Updated protocool specs.
1271 * Updated INSTALL and README files.
1273 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * New web pages in the http://silc.pspt.fi. The pages was
1280 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Implemented the [DenyConnectin] config section in the server.
1283 Added silc_server_config_denied_conn to check whether incoming
1284 connection is denied. Affected file silcd/serverconfig.[ch].
1286 * Do not check the ports when checking the incoming configuration
1287 data if the port is 0, meaning any. Affected file is
1288 silcd/serverconfig.c.
1290 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Fixed buffer overflow in silc_string_compare in the file
1293 lib/silcutil/silcutil.c.
1295 * Fixed double free in silc_server_command_leave in the file
1298 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Fixed the version checking in the server. Affected file is
1303 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1305 * Fixed the configuration data fetching when accepting new
1306 connections in the server. Affected file silcd/server.c.
1308 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Added `sender_entry' argument to the function
1311 silc_server_packet_relay_to_channel so that we can check
1312 whether some destination actually belongs to the same route
1313 the sender belongs (ie, we must not resend the packet to the
1314 sender). Affected file silcd/packet_send.[ch].
1316 * Added `servername' field to the SilcClientEntry in the server
1317 to hold the name of the server where client is from. Affected
1318 file is silcd/idlist.h.
1320 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1322 * Moved the channel message encrypting in the router betwen
1323 router connections from silc_server_channel_message to the
1324 silc_server_packet_relay_to_channel since we want to check
1325 whether we have anybody channel before encrypting anything.
1326 Affected files silcd/packet_[receive/send].c.
1328 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1330 * Fixed the [AdminConnection] server config section to support
1331 multiple entries. Affected file silcd/serverconfig.c.
1333 * Added support into the server to check the validity of the
1334 incoming connection before executing any KE or authentication
1337 * The connection configuration is now saved to the KE and
1338 connection auth protocol contexts and not fetched anymore in
1339 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1341 * The local hosts listenning address and port is also resolved
1342 now when starting the server. We want to have the socket object
1343 to include the real address and port for the listener. Added
1344 new function silc_net_check_local_by_sock into the files
1345 lib/silcutil/silcnet.[ch].
1347 * Fixed a broadcast bug in server -> do not broadcast if we
1350 * Fixed a routing bug. Do not route broadcast packets ever.
1351 Broadcast packets must be processed always and not routed since
1352 they may be destined to some other host than yourself and thus
1353 would get routed without no good reason. Affected file is
1356 * Added function silc_server_config_is_primary_route to check
1357 whether primary router connection has been configured (a router
1358 configuration that we are initiating). If there is not, we
1359 will assume that there is only two routers in the SILC network
1360 and we will use the incoming router connection as our primary
1361 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1363 * Changed the order of the broadcasting. Broadcast _after_ the
1364 packet has been processed not before. Affected file is
1367 * Fixed a [ClientConnection] parsing bug. The port was never
1368 parsed correctly thus resulting to port 0. Affected file
1369 silcd/serverconfig.c.
1371 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1372 argument and did not set the broadcast packet flag. Affected
1373 file silcd/packet_send.c. Fixed same bug in the function
1374 silc_server_send_notify as well.
1376 * If we receive NEW_ID packet for our own ID in the server, ignore
1379 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Removed the nickname from the Private Message Payload.
1384 Updated the code and the protocol specs.
1386 * Updated protocol specs for submitting to the IETF.
1388 * Tweaked the Random Number Generator a bit. Affected file
1389 lib/silccrypt/silcrng.c. Exported a new function
1390 silc_rng_[global]_add_noise which can be used to add more
1393 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Do not parse packets with different timeout when protocol
1396 is active -> may cause problem with rekey. Affected file
1399 * When server receives signoff notify it must not create
1400 new channel key if the client is on any channels since the
1401 sender of the signoff notify will create it.
1403 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Added printing of error messages during SKE protocol from the
1406 failure packet sent by server during SKE. Affected file
1409 * Removed the client's failure_callback handling with timeout
1410 and handle it immediately when received.
1412 * The SKE library returned wrong type in SUCCESS and FAILURE
1413 packets. They must be 32 bit MSB not 16 bit MSB.
1415 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1417 * Ok, rewrote the logic of the re-key and now it seems to work.
1418 I tested it on high traffic with frequent re-keys without
1419 problems. Added hmac_receive (and renamed hmac to hmac_send)
1420 in SilcClientConnection in lib/silcclient/client.h and
1421 in SilcIDListData in silcd/idlist.h. Also, removed the
1422 SilcPacketParserContext's cipher and hmac fields as they are
1423 not needed anymore and actually caused some problems when
1424 the ciphers and hmac's changed underneath the packet parser.
1426 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * If re-key protocol is active then process the incoming packets
1429 synchronously since we must assure that icoming packets encrypted
1430 with the old key is processed before the new keys is set to
1431 use. This is true other packets than for REKEY packets.
1432 Affected file silcd/server.c. The same was done to client library
1433 as well, affected file lib/silcclient/client.c.
1435 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Fixed bug in client and server to accept the force send if
1438 the packet is send from silc_[server/client]_packet_process
1439 function. Otherwise the packets are never delivered, oops.
1441 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Disable force sending of packets when REKEY protocol is active.
1444 We must assure that no packet is sent directly when rekey is
1445 performed. All packets must be sent through packet queue.
1446 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1447 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1448 function is silc_[server/client]_packet_send_real to check
1451 * Replaced the SIM paths from example config files to
1452 /usr/local/modules. Also, make install creates now
1453 /usr/local/silc/logs directory to hold all the SILC server
1456 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Made the configure.in.pre work on Solaris. Patch by salo.
1460 * Made all ciphers compatible with non-x86 machines. Defined
1461 CBC mode macros into lib/silccrypt/ciphers_def.h.
1463 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Fixed the make install.
1467 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * When MAC computation fails the silc_packet_decrypt returned 0
1470 even though it was supposed to return -1. Fixed this. The
1471 affected file is lib/silccore/silcpacket.c.
1473 * Do not replace the config files in /etc/silc (in make install)
1474 if they already exist. Affected file ./Makefile.am.
1476 * Do not send re-key packets immediately but through packet queue.
1477 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1479 * Changed silc_net_check_host_by_sock to return FALSE if the
1480 IP/DNS could not be resolved. Though, it returns the IP address
1481 now even if it could not resolve it (but returns also FALSE).
1482 Affected file lib/silcutil/silcnet.[ch].
1484 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1486 * Added silc_pkcs_decode_identifier to decode the public key's
1487 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1488 Added also silc_pkcs_free_identifier. Added also new context
1489 SilcPublicKeyIdentifier.
1491 * Added -S option to the silc client. It is used to dump the
1492 contents of the specified public key file.
1494 * Changed the PKCS api to return the public key length when
1495 setting the public key.
1497 * Fixed a fatal bug in the public and private key file loading.
1498 Affected file lib/silccrypt/silcpkcs.c.
1500 * Execute the packet parsing for client with zero (0) timeout
1501 if the protocol is active. Affected file silcd/server.c.
1503 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1505 * Made the key generation options to the silcd program. Added
1506 -C option, equivalent to client's option.
1508 * Added new [ServerKeys] config section to the server. It
1509 configures the server's public and private key.
1511 * Defined generic Public Key Payload into the protocol
1512 specification to send specific type of public keys and
1515 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1516 public key or certificate.
1518 * Implemented the GETKEY command to the server and to the
1519 client library and on user interface.
1521 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Made preliminary `make install' work.

1552 SilcClientConnection structure; not needed. Affected file is
1553 lib/silcclient/client.h.
1557 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Do not ask whether user wants to use the negotiated private key
1560 for private messages, just use it. Affected file is
1561 silc/local_command.c.
1563 * Added `send_enc_key' and `enc_key_len' fields to the
1564 SilcIDListData structure since they are needed in the re-key
1565 phase. Affected file is silcd/idlist.[ch].
1567 * Implemented the simple re-key protocol into the server.

1579 the PFS is to be performed in the re-key. Affected file is
1582 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1585 int64 of at least the xintXX size. If void * is less that 4
1586 bytes uint32 * will be used. Defined bool as boolean.
1588 * Changed _ALL_ unsigned long and unsigned int to uint32,
1589 unsgined short to uint16 in the source tree.
1591 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1592 not handle clients that has entry->data.registered == FALSE.
1593 They are not in the network anymore. Affected file is
1596 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Implemented the sending of the SERVER_SIGNOFF notify in the
1599 server. Affected file is silcd/server.c.
1601 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1602 Added also silc_notify_payload_encode_args into the

1605 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1606 Affected file silcd/packet_receive.c.
1608 * Implemented the SERVER_SIGNOFF notify handling in the client
1609 library. Affected file lib/silcclient/client_notify.c. Also,
1610 implemnted the printing of the SERVER_SIGNOFF info to the
1611 application. Affected file silc/client_ops.c.
1613 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1614 if the deleting was successful. Affected file silcd/idlist.[ch].
1616 * Added support for public key authentication in the connection
1617 authentication protocol in the client library. Affected file
1618 lib/silcclient/protocol.c.
1620 * Changed the server's silc_idlist_get_clients_by_* interface
1621 to support already allocated array so that new entries may be
1622 added to pre-allocated array. Affected file silcd/idlist.[ch].
1623 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1624 and command replies.
1626 * All command reply functions in the server now calls the
1627 pending command callback even if error occured. This way the
1628 error will be delivered to the client as well. Affected files
1629 silcd/command.c and silcd/command_reply.c.
1631 * Fixed INFO command to return local server's info if no server
1632 was provided. Affected file lib/silcclient/command.c.
1634 * Removed RESTART command for good. Updated the code and the
1637 * Rewrote parts of the task system. It is a bit simpler now.
1638 Removed unsued task priorities. The affected files are
1639 lib/silcutil/silctask.[ch].
1641 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1643 * Moved the USERS printing from the library to the application.
1644 Affected files lib/silcclient/command.c and silc/client_ops.c.
1646 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1650 * Added channel key re-key support. The re-key is perfomed
1651 only by the router and is done once in an hour. Added `rekey'
1652 field to the SilcChannelEntry in the server. Affected files
1653 silcd/server.c and silcd/idlist.h.
1655 * Added silc_task_unregister_by_context into the file
1656 lib/silcutil/silctask.[ch].
1658 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Added SILC_UMODE_GONE mode to indicate when the client is not
1661 present in the SILC network. Added also support to the local
1662 command AWAY that will set this mode. Added support of showing
1663 "xxx is gone" in WHOIS command. The USERS command shows the
1664 gone status as well.
1666 * Fixed setting server and router operator privileges in the
1667 server's UMODE command. Affected file silcd/command.c.
1669 * Merged the SKE KE1 and KE2 payloads into one payload. The
1670 new KE payload is equivalent to the old KE2 payload.
1672 Cleaned up the SKE Start Payload parsing. It now uses the
1673 simple buffer unformatting to do the parsing. A lot faster
1676 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1677 to the SKE that is used to indicate whether both of the SKE
1678 parties should perform authentication. By default only the
1679 responder performs authentication. By setting this flag also
1680 the initiator must do authentication. By default it is unset
1681 since in normal SKE case, client to server connection, only
1682 the responder should do authentication. When doing SKE between
1683 two clients both should perform authentication. Updated the
1684 code and the protocol specs.
1686 * A little fix to IDENTIFY command in the server. Search the
1687 client first by hash not nickname. Affected file is
1690 * Fixed the silc_client_close_connection to support closing
1691 the client to client connections wihtout deleting too much
1692 data. Affected file lib/silcclient/client.c.
1694 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1695 are received if protocol used to be active but is not anymore
1696 the application would crash due to NULL pointer dereference.
1697 Affected files silcd/server.c and lib/silcclient/client.c.
1699 * Added `hash' field to the SilcClientConnection to include
1700 the hash function negotiated in the SKE protocol.
1702 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1703 to set the channel founder authentication data. A client can
1704 claim the founder rights later by providing the authentication
1705 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1706 This way the channel founder can regain the channel founder
1707 privileges even it is left the channel. This works only on
1708 local server and the client must be connected to the same
1709 server to be able to regain the founder rights. Updated the
1710 protocol specs accordingly.
1712 Added support to the CMODE command in the client to set the
1713 founder auth data. Read the README to see how to set it.
1715 Added support to the CUMODE command to claim the founder
1716 rights. Read the README to see how to do it.
1718 Added support for the founder authentication to the Channel
1719 Entry in the server. Affected file silcd/idlist.h.
1721 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1722 server's CMODE command. Affected file silcd/command.c.
1724 * Added the following new functions into lib/silccore/silcauth.[ch]:
1725 silc_auth_get_method and silc_auth_get_data.
1727 * The server now saves the remote hosts public key to the
1728 SilcIDListData pointer. Affected file silcd/protocol.c.
1730 * The normal server now does not remove the channel entry from
1731 the cache if the founder authentication data is set. It used
1732 to remove it if the founder was the last one on the channel on
1733 the server and left the channel. The auth data is saved and
1734 if the channel is re-joined later the old entry is used with
1735 the old auth data. Affected files silcd/command_reply.c and
1738 * Removed the `pkcs' field from the SilcIDListData structure
1739 in the server; it is not used. Affected file silcd/idlist.h.
1741 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Fixed packet processing on slow links. Partial packets were
1744 never re-processed because the incoming data buffer was cleared
1745 by the application. Application must not directly clear the
1746 sock->inbuf, the packet processing routines handle it. Fixed
1747 this in client library and in server.
1749 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Fixed the WHOIS and IDENTIFY send reply function to really
1752 check whether to send list or just one entry. Affected file
1755 * Cleaned up the LEAVE command's channel key distribution. The
1756 affected file silcd/command.c.
1758 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1759 can enforce the channel mode as well. In that case the ID
1760 includes the ID of the server. The code now enforces the
1761 mode change if the router have different mode than the server.
1763 * The notify client operation with CMODE_CHANGE notify can now
1764 return NULL client_entry pointer if the CMODE was not changed
1765 by client. Application must check for this.
1767 * Added <Server ID> argument to INFO command to support server
1768 info fetching by Server ID.
1770 * Added silc_server_announce_get_channel_users to get assembled
1771 packets of channel users of the specified channel. Affected
1772 file silcd/server.[ch].
1774 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1775 was freed underneath the ID Cache.
1777 * Re-announce clients when the server received CHANNEL_CHANGE
1778 notify from the router. Affected file silcd/packet_send.c.
1780 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1783 crashed since it did not handle the fact that there is no cipher
1784 called "3" and didn't check the error condition. Now fixed.
1786 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1787 flag. It can be used to send message requests.
1789 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1791 * Implemented the RESTART command in the client.
1793 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1794 notice type messages. Added notice printing to the user
1797 * The channel keys are not re-generated if the channel's mode
1798 is PRIVKEY, ie private key on the channel exists. Affected
1799 files silcd/server.c and silcd/command.c.
1801 * Fixed a little bug in channel message delivery when channel
1802 private keys are set in the server. Affected file is
1803 silcd/packet_send.c.
1805 * Changed the setting on channel->on_channel = TRUE from the
1806 silc_client_save_channel_key to the JOIN command reply. The
1807 key payload is not received if the private channel key is set.
1808 Affected file lib/silcclient/command_reply.c and the
1809 lib/silcclient/client_channel.c.
1811 * When the CMODE_CHANGE notify is sent and the channel private
1812 key mode is removed the channel key must be re-generated in
1813 other cells as well. Added this support for the router in the
1814 silcd/packet_receive.c.
1816 * Added new local command NOTICE to send notice message on
1817 channel. Affected file silc/local_command.[ch].
1819 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Added new local command ME to the client. It is used to send
1822 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1823 some action. Affected file silc/local_command.[ch].
1825 * Changed channel_message and private_message client operations
1826 to deliver the message flags to the application. Added also
1827 the `flags' arguments to the silc_client_send_channel_message
1828 and silc_client_send_private_message functions. Affected file
1831 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Redefined the Private Message Payload to support private message
1834 keys and to support the new private message flags. Updated
1835 the protocol specs. Flags makes it possible to have for example
1836 CTCP style messages.
1838 * Added new type SilcPrivateMessagePayload and defined an API
1839 for it in the lib/silcclient/silcprivate.[ch].
1841 * Tested private message private keys successfully. Tested the
1842 private message key set, unset and list commands with the new
1845 * Redefined the Channel Message Payload to include the channel
1846 message flags (equal with private message flags) to support
1847 for example CTCP style messages.
1849 * Defined some of the message (for channel and private message)
1850 flags. Updated the protocol specs and added the flags to the
1851 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1853 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Added SilcKeyAgreementStatus type to the key agreement routines
1856 to indicate the current status and error if one occured.
1857 The status types are defined in the lib/silcclient/silcapi.h.
1859 * Added new local command KEY that is used to set and unset private
1860 keys for channels, set and unset private keys for private messages
1861 with remote clients and to send key agreement requests and
1862 negotiate the key agreement protocol with remote client. The
1863 key agreement is supported only to negotiate private message keys,
1864 it currently cannot be used to negotiate private keys for channels,
1865 as it is not convenient for that purpose.
1867 * Fixed a minor pending callback setting bug in the function
1868 silc_client_get_client_by_id_resolve, now the function works.
1869 Affected file lib/silcclient/idlist.c.
1871 * Added function silc_net_get_local_port to get local bound
1872 port by socket. Added to lib/silcutil/silcnet.[ch].
1874 * Added `sockets' and `sockets_count' fields to the SilcClient
1875 object. They hold the sockets of the listenning sockets in
1876 the client. Listenning sockets may be for example the key
1877 agreement server. Affected file lib/silcclient/client.[ch].
1878 Added functions the silc_client_add_socket and the
1879 silc_client_del_socket. They are exported to the application
1882 * Added ~./silc/clientkeys to support other client's public keys.
1884 * Renamed verify_server_key client operation to verify_public_key
1885 and added one argument to indicate the type of the connection
1886 (server, client etc.).
1888 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added silc_server_connection_auth_request to handle the
1891 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1892 silcd/packet_receive.[ch].
1894 * Added silc_server_send_connection_auth_request into the
1895 silcd/packet_send.c to send the connection auth request packet.
1897 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1900 * Fixed the public key authentication in responder side in the
1901 server. The `auth_data' pointer includes the SilcPublicKey
1902 not the path to the public key. Affected file silcd/protocol.c.
1904 * Implemented the public key authentication in the initiator side
1905 in the server. Affected file silcd/protocol.c.
1907 * Removed the [RedirectClient] config section from the server
1908 configuration. Is not needed and I don't want to implement it.
1910 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Cleaned up the CMODE command in the server. It now works
1913 correctly and supports all the modes defined in the protocol.
1914 Affected file is silcd/command.c.
1916 * Added `hmac_name' field to the SilcChannelEntry in the server
1917 to hold the default HMAC of the channel. It can be set when
1918 creating the channel (with JOIN command). Affected files
1921 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1922 type to indicate the change of the current cipher and hmac
1923 on the channel. Client can safely ignore the <cipher> argument
1924 (if it chooses to do so) since the CHANNEL_KEY packet will
1925 force the channel key change anyway. The <hmac> argument is
1926 important since the client is responsible of setting the new
1927 HMAC and the hmac key into use.
1929 * Fixed the CMODE command in the client library as well.
1931 * Tested CMODE command in router environment successfully.
1933 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Show the version of the remote client (or server) when connecting
1936 to the server. It is logged to the log file. Affected file
1937 is silcd/protocol.c.
1939 * Fixed the KILLED notify handling in the client library. The
1940 client must be removed from all channels when receiving the
1943 Also, do not remove the client entry when giving the KILL
1944 command but when the KILLED notify is received.
1946 * Removed silc_idlist_find_client_by_nickname from the server.
1947 Not needed anymore. Affected files silcd/idlist.[ch].
1949 * Implemented the CHANNEL_CHANGE notify type handling to the
1950 server. Affected file silcd/server.c.
1954 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1956 * Added silc_server_send_notify_invite to send the INVITE
1957 notify between routers.
1959 * Implemented the INVITE command correctly to the server.

1968 * Added function silc_server_get_client_resolve to find the
1969 client entry by ID from all ID lists and then resolve it
1970 (using WHOIS) if it cannot be found. Affected file is
1973 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Implemented the BAN command to the client library.
1977 * The JOIN command in the server now checks the invite list
1980 * Changed the silc_command_reply_payload_encode_va and the
1981 silc_command_payload_encode_va to support that if argument is
1982 NULL it ignores and checks the next argument. Affected file
1983 lib/silccore/silccommand.c.
1985 * Added silc_server_send_notify_ban to send the BAN notify
1986 type between routers.
1988 * Chaned the silc_notify_payload_encode to support that if
1989 argument is NULL it ignores and checks the next argument.
1990 Affected file lib/silccore/silcnotify.c.
1992 * Tested ban lists in router environment successfully.
1994 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Implemented BAN command to the server, in silcd/command.[ch].
1998 * Removed the BAN and INVITE_LIST modes from the CMODE command
2001 * Added function silc_string_match to regex match two strings.
2002 Affected files lib/silcutil/silcutil.[ch].
2004 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Redefined parts of the SilcChannelEntry in the server to support
2007 the new ban and invite lists.
2009 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Redefined the INVITE command. The same command can be used to
2012 invite individuals to the channel but also to manage the invite
2013 list of the channel (to add to and remove from the invite list).
2014 Updated the protocol specs.
2016 * Added new command SILC_COMMAND_BAN that can be used to manage
2017 the ban list of the channel. Updated the protocol specs.
2019 * Removed the channel modes: the SILC_CMODE_BAN and the
2020 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2021 in the CMODE command. The equivalent features are now available
2022 using INVITE and BAN commands. Updated the protocol specs.
2024 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2025 in the network about change in the current ban list. The notify
2026 type is not used by the client.
2028 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2029 support the invite lists.
2031 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2033 * Added new function silc_string_regexify that converts string
2034 including wildcard characters into regex string that can
2035 be used by the GNU regex library. Added into the file
2036 lib/silcutil/silcutil.[ch].
2038 Added silc_string_regex_combine to combine to regex strings
2039 into one so that they can be used as one regex string by
2040 the GNU regex library. Added into the file
2041 lib/silcutil/silcutil.[ch].
2043 Added silc_string_regex_match to match two strings. It returns
2044 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2046 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * Imported GNU regex to the soruce tree into lib/contrib.
2049 Fixed some compiler warning from the regex.c.
2051 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2059 in the server, as the `nickname' argument may be binary data
2062 * Added silc_idlist_get_channels to return all channels from
2065 * Implemented LIST command to the server. Affected file is
2068 * Implemented the LIST command to the client library and on the
2071 * Added [<user count>] argument to the LIST command reply.
2072 With private channels the user count is not shown.
2074 * Updated TODO and README.
2076 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * The client entry's data.registered must be TRUE even with
2079 global client entry on global client list. The data.registered
2080 is used to check whether the client is anymore in the network,
2081 for example with WHOWAS command so it must be valid.
2083 * Fixed the WHOWAS command in the server. It now actually works
2084 in router environment. Added function into silcd/command_reply.c
2085 silc_server_command_reply_whowas_save.
2087 * Added silc_idlist_purge function to the silcd/idlist.c
2088 to periodically purge the ID Cache.

2098 they were buggy because of the WHOWAS information.
2100 * Fixed local command MSG to handle the async resolving of
2101 the remote client properly. It used to fail the first MSG.
2102 Affected file silc/local_command.c.
2104 * Added `data_len' field to SilcIDCache context.
2106 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Update TODO. Todo in commands in the server.

2117 silcd/packet_receive.c. Added the function
2118 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2120 * Added new generic Channel Payload and deprecated the New Channel
2121 Payload. The New Channel Payload is now the generic Channel
2124 * Added new argument `mode' to the silc_server_send_new_channel
2125 as it is required in the Channel Payload now.
2127 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2128 and created a new and real SilChannelPayload to represent the
2129 new generic Channel Payload. Implemented the encode/decode
2130 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2132 * Added silc_server_get_client_channel_list to return the list
2133 of channels the client has joined for WHOIS command reply.
2134 Affected file silcd/server.[ch].
2136 * Implemented the channel list sending in the WHOIS command reply
2137 in server and in the client.
2139 Implemented the channel list displaying on the user interface
2140 as well. Affected file silc/client_ops.c.
2142 * Added silc_channel_payload_parse_list to parse list of Channel
2143 Payloads. It returns SilcDList list of SilcChannelPayloads.
2144 Client for example can use this function to parse the list of
2145 channels it receives in the WHOIS command reply. The caller
2146 must free the list by calling silc_channel_payload_list_free.
2147 Affected files lib/silccore/silcchannel.[ch].
2149 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Added one new argument <user mode> to the WHOIS command reply

2168 unknown command. Affected file silcd/command.c.
2170 * All server commands now handle the command identifier the right
2171 way when sending the command reply to the client. The client can
2172 use to identify the command replies with the identifier.
2174 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Added silc_server_get_client_route to resolve the route to
2177 the client indicated by the client ID. Affected file is
2180 * Added silc_server_relay_packet as general function to relay
2181 packet to arbitrary destination. This deprecates functions
2182 like _send_private_message_key, _relay_notify etc. Affected
2183 file is silcd/packet_send.[ch].
2185 Removed silc_server_send_key_agreement,
2186 silc_server_send_private_message_key and
2187 silc_server_packet_relay_notify functions from the file
2188 silcd/packet_send.[ch].
2192 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2193 server. Affected file silcd/packet_receive.[ch].
2195 * Implemented the KILL command to the client. Implemented the
2196 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2197 Affected files lib/silcclient/command[_reply].c and
2198 lib/silcclient/client_notify.c. Implemented the KILL notify
2199 printing in the user inteface.
2201 * Fixed a lot silc_parse_nick memory leaks from the client
2202 library in the file lib/silcclient/command.c.
2204 * Changed the silc_server_send_notify_on_channels's `sender'
2205 argument from SilcSocketConnection to SilcClientEntry to
2206 check the sender as entry and not as connection object and not
2207 to send to the client provided as argument. The affected file
2208 is silcd/packet_send.[ch].
2210 * The notify packets that are destined directly to the client used
2211 to not to be processed by the server. Now changed that and the
2212 server processes all notify packets. After relaying the packet
2213 to the client the notify packet is processed in the server.
2215 * The silc_server_free_client_data now checks whether there is
2216 pending outgoing traffic for the client and purges the data to
2217 the network before removing the client entry.
2219 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2222 an client is killed from the SILC Network. Updated the protocol
2225 Added new function silc_server_send_notify_killed to the
2226 silcd/packet_send.[ch].
2228 * Added function silc_server_packet_relay_notify to relay notify
2229 packets that are destined directly to a client. In this case
2230 the server does not process the notify packets but merely relays
2231 it to the client. Affected file silcd/packet_send.[ch].
2233 Added also silc_server_packet_process_relay_notify to check
2234 whereto relay the notify. Affected file is
2235 silcd/packet_receive.[ch].
2237 * Implemented the KILL command to the server.
2241 * Added the backup schema desgined last fall to the protocol
2242 specs for everyone to see. The specification is in the
2243 *-spec-xx.txt draft and the packet type definitions for the
2244 backup routers is in *-pp-xx.txt draft. Thusly, added also
2245 new packet type SILC_PACKET_CELL_ROUTERS.
2247 * A big security problem in the implementation discovered. The
2248 signoff of an client did not cause new channel key generation
2249 which it of course should've done. The channel keys must be
2250 always re-generated when client leaves (or signoffs) the channel.
2251 The silc_server_remove_from_channels funtion now handles
2252 the channel key re-generation.
2254 * Added `sender' argument to the silc_server_send_notify_on_channels
2255 to not to send the client provided as argument. Affected file
2256 silcd/packet_send.[ch].
2258 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Implemented OPER and SILCOPER commands into the server and
2263 * Added silc_auth_verify and silc_auth_verify_data to verify
2264 the authentication directly from the authentication payload.
2265 It supports verifying both passphrase and public key based
2266 authentication. Affected file lib/silccore/silcauth.[ch].
2268 * Added `hash' field to the SilcIDListData structure. It is the
2269 hash negotiated in the SKE protocol. Affected file is
2272 * Slight redesigning of the SilcAuthPayload handling routines.
2273 Do not send SilcPKCS but SilcPublicKey as argument.
2275 * Implemented the public key authentication support to the
2276 serverconfig. The public key is loaded from the provided path
2277 and saved as authentication data to void * pointer. Thus,
2278 changed the unsigned char *auth_data to void *auth_data;
2280 * Fixed SHUTDOWN command to send the reply before the server
2281 is shutdown. :) Affected file silcd/command.c.
2283 * Fixed fatal bug in CONNECT command. The hostname was invalid
2284 memory and server crashed. Affected file silcd/command.c.
2286 * Fixed fatal bug in CLOSE command. The server_entry became
2287 invalid but was referenced later in the command. Affected file
2290 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Fixed fatal bug in failure packet handling. Server ignored
2293 the failure and thus crashed when it came.
2297 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2300 that the command may be executed only once in (about) 2 seconds.
2301 The old SILC_CF_LAG flag is same but allows command bursts up
2302 to five before limiting.
2304 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2305 server code. Various commands now includes the CF_LAG_STRICT
2306 flag to disallow any kind of miss-use of the command.
2308 * Fixed the silc_buffer_unformat to not to allocate any data
2309 if the length of the data is zero. It used to allocate the
2310 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2312 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Changed the format of AdminConnection configuration section
2315 in the server. Added username of the admin to the format.
2316 Affected files silcd/serverconfig.[ch].
2318 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2319 to return admin configuration data by host, username and/or
2322 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Implemented WHOWAS command to the server. Added the functions:
2326 silc_server_command_whowas_parse,
2327 silc_server_command_whowas_send_reply,
2328 silc_server_command_whowas_from_client and
2329 silc_server_command_whowas_from_server
2331 * Added <Client ID> argument to the WHOWAS command reply. Updated
2332 the protocol specs accordingly.
2334 * Implemented WHOWAS command and command_reply to the client
2337 Implemented the WHOWAS printing on the user interface.
2339 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Added new argument to the WHOWAS command reply, the real name.
2342 It is an optional argument. Updated the protocol specs.
2344 * Added SilcIDCacheDestructor callback that is registered when
2345 the SilcIDCache is allocated. The callback is called when
2346 an cache entry in the ID Cache expires, or is purged from the
2347 cache. Added into lib/silccore/idcache.[ch].
2349 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2350 to destruct the client entries when the cache entry expires.
2351 Other ID Cache's in server and in the client library ignores
2354 * If the ID Cache entry's `expire' field is zero then the entry
2355 never expires. Added boolean `expire' argument to the
2356 silc_idcache_add function in the lib/silccore/idcache.[ch].
2357 If it is TRUE the default expiry value is used.
2359 * Added silc_server_free_client_data_timeout that is registered
2360 when client disconnects. By default for 5 minutes we preserve
2361 the client entry for history - for WHOWAS command.
2363 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Added support to the server to enforce that commands are not
2366 executed more than once in 2 seconds. If server receives
2367 commands from client more frequently, timeout is registered
2368 to process the commands. Affected file silcd/command.c.
2369 Added new function silc_server_command_process_timeout.
2371 * Changed NICK_NOTIFY handling in client library to check that
2372 if the client's nickname was changed, so there is no need to
2373 resolve anything from the server.
2375 * Removed error printing from the WHOIS and IDENTIFY commands.
2376 If error occurs then it is ignored silently in the client library.
2377 The application, however, may map the received error to
2378 human readable error string. The application currently maps
2379 the NO_SUCH_NICKNAME error to string.
2381 * Made the command status message public to the application. Moved
2382 them from lib/silcclient/command_reply.c to
2383 lib/silcclient/command_reply.h. The application can map the
2384 received command status to the string with the
2385 silc_client_command_status_message function.
2387 * Added check to the server to check that client's ID is same
2388 as the Source ID in the packet the client sent. They must
2391 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2393 * Added dist-bzip hook to the Makefile.am to make bzip2
2394 compressed distributions.
2396 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Server now enforces the maximum length for the nickname and
2399 the channel as protocol specification dictates. 128 bytes for
2400 nickname and 256 bytes for channel name.
2402 * Moved the WHOIS printing to the application. The client libary
2403 does not print out the WHOIS information anymore, the application
2404 must do it. Renamed silc_client_command_reply_whois_print to
2405 the silc_client_command_reply_whois_save.
2407 The client's idle time is also sent to the application now, and
2408 the idle is shown on screen.
2410 * Added silc_client_command_reply_identify_save to save the
2411 received IDENTIFY entries.
2413 * Do not check for channel private keys in message sending and
2414 reception if the channel does not have the PRIVKEY mode set.
2415 Affected file lib/silclient/client_channel.c.
2417 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2420 just surfaced after chaning the JOIN procedure.
2422 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Added silc_client_get_clients_by_list to get client entries
2425 from Client ID list, that is returned for example by JOIN
2426 and USERS command replies. The application should use this
2427 function for example when JOIN command reply is received to
2428 resolve the clients already on the channel (library does not
2429 do that anymore as USERS command reply is not used in the JOIN
2430 procedure anymore). Affected files lib/silcclient/silcapi.h and
2431 lib/silcclient/idlist.c.
2433 * JOIN command reply and USERS command reply returns now SilcBuffer
2434 pointers instead of unsigned char pointers when returning
2435 the client list and mode list.
2437 * Added <Client ID> argument to the JOIN command reply, mainly
2438 for the server to identify for which client the command was
2439 originally sent. Updated protocol specs accordingly.
2441 * Added SilcDlist private_key pointer to the SilcChannelEntry
2442 in the client to support the channel private keys. Affected
2443 file is lib/silcclient/idlist.h.
2445 * Added SilcChannelPrivateKey argument to the function
2446 silc_client_send_channel_message so that application can choose
2447 to use specific private ke if it wants to. If it is not provided,
2448 the normal channel key is used, unless private keys are set.
2449 In this case the first (key that was added first) is used
2450 as the encryption key.
2452 * Implemented the support for channel private key handling.
2453 Implemented the following functions:
2455 silc_client_add_channel_private_key,
2456 silc_client_del_channel_private_keys,
2457 silc_client_del_channel_private_key,
2458 silc_client_list_channel_private_keys and
2459 silc_client_free_channel_private_keys
2461 Affected file lib/silcclient/client_channel.c.
2463 * Added the support for the private keys in the channel message
2464 sending and encryption and in the message reception and
2465 decryption. Affected funtions are
2466 silc_client_send_channel_message and silc_client_channel_message.
2468 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Added SKE's key verify callback to the client library's
2471 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2473 * Removed the statement that server (or router) must send USERS
2474 command reply when joining to the channel so that the client
2475 knows who are on the channel. Instead, the client list and
2476 client's mode list is now sent in the JOIN command reply to the
2477 client who joined channel. This is better solution.
2479 * Added function silc_server_get_users_on_channel and function
2480 silc_server_save_users_on_channel to the silcd/server.[ch].
2482 * Removed function silc_server_command_send_users from the
2485 * Do not show topic on the client library anymore. The topic is
2486 sent in the command reply notify to the application and the
2487 application must show the topic now.
2489 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Added client searching by nickname hash into the IDENTIFY and
2492 WHOIS commands in the server as they were clearly missing from
2493 them. Affected file is silcd/command.c.
2495 * Fixed a bug in private message receiving in the client library.
2496 The remote ID was freed and it wasn't supposed, now it is
2499 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Minor fix to the channel payload; allocate the data area, as it
2502 needs to be of specific length.
2504 * If the key agreement port is zero then the operating
2505 system will define the bound port. Affected files are
2506 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2508 * Added new function silc_channel_payload_decrypt into the file
2509 lib/silccore/silcchannel.[ch].
2511 * Moved the channel message etc, check from silc_packet_decrypt
2512 to applications. The library calls now a generic
2513 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2514 when the packet is either normal or special. This was done to
2515 allow more wide range of checking that was not allowed when
2516 the code was in library. Now applications can do virtually any
2517 checks to the packet and return to the library the decision how
2518 the packet should be processed. Affected files are
2519 lib/silccore/silcpacket.[ch].
2521 Added silc_server_packet_decrypt_check to the server and
2522 silc_client_packet_decrypt_check to the client library.
2524 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2525 to send with specified source and destination information.
2527 * Channel message delivery between routers was broken after the
2528 channel key distribution was fixed earlier. The channel key
2529 was used be to distributed to other routers as well which is not
2530 allowed by the protocol. Now this is fixed and channel keys
2531 really are cell specific and the channel message delivery between
2532 routers comply with the protocol specification.
2534 * Fixed various commands in server to check also the global list
2535 for the channel entry and not just the local list. The affected
2536 file silcd/command.c.
2538 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Added assert()s to buffer formatting and unformatting routines
2541 to assert (if --enable-debug) when error occurs. Affected
2542 file: lib/silcutil/silcbuffmt.c.
2544 * Changed to auto-reconnect to check whether the remote host is
2545 router and register the re-connect timeout if it is. It used
2546 to check that whether we are normal server, but router must do
2547 auto-reconnect with another router as well. Affected file
2550 * Removed the [<key len>] option from CMODE command as the cipher
2551 name decides the key length, nowadays. See the defined ciphers
2552 from the protocol specification.
2554 * Added [<hmac>] option to the CMODE command to define the HMAC
2555 for the channel. Added SILC_CMODE_HMAC channel mode.
2557 * Added [<hmac>] option for the JOIN command so that user can
2558 select which HMAC is used to compute the MACs of the channel
2561 * Added Hmac field to the Channel Message Payload. The integrity
2562 of plaintext channel messages are now protected by computing
2563 MAC of the message and attaching the MAC to the payload. The
2564 MAC is encrypted. Now, it is clear that this causes some
2565 overhead to the size of the packet but rationale for this is that
2566 now the receiver can verify whether the channel message decrypted
2567 correctly and also when private keys are set for the channel the
2568 receiver can decrypt the packet with several keys and check from
2569 the MAC which key decrypted the message correctly.
2571 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2572 lib/silccrypt/silccipher.[ch].
2574 * Added silc_hash_len to return the digest length into the
2575 lib/silcrypt/silchash.[ch].
2577 * Rewrote parts of Silc Channel Payload interface in the
2578 lib/silccore/silcchannel.[ch]. The encode function now also
2579 encrypts the packet and parse function decrypts it.
2581 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Fixed a minor formatting bug in the SKE's key material processing.
2584 It actually might have processed the keys wrong way resulting
2587 * Redefined the mandatory HMAC algorithms and added new algorithms.
2588 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2589 and hmac-md5 truncated to 96 bits. The mandatory is now
2590 hmac-sha1-96. Rest are optional (including the one that used
2591 to be mandatory). Rationale for this is that the truncated HMAC
2592 length is sufficient from security point of view and can actually
2593 make the attack against the HMAC harder. Also, the truncated
2594 HMAC causes less overhead to the packets. See the RFC2104 for
2597 * Added new [hmac] configuration section. The SKE used to use
2598 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2599 is of course wrong. The official names that must be proposed in
2600 the SKE are the ones defined in the protocol specification
2601 (hmac-sha1-96 for example). The user can configure any hmac
2602 using any hash function configured in the [hash] section. At
2603 least, the mandatory must be configured.
2605 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2607 * Added HMAC list to the SKE proposal list. It has now both
2608 hash algorithm list and HMAC list. This makes the protocol
2609 incompatible with previous versions. The SKE now seems to work
2610 the way it is supposed to work, for the first time actually.
2612 * Defined plain Hash algorithms to the protocol specification.
2615 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Implemented support for key agreement packets into the server.
2618 Added functions silc_server_key_agreement and
2619 silc_server_send_key_agreement. Other than these functions,
2620 server has nothing to do with this packet.
2622 * Added support for private message key packets into the server.
2623 Added functions silc_server_private_message_key and
2624 silc_server_send_private_message_key.
2628 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2629 called in the protocol's final callback instead in the END
2630 protocol state. This makes a little more sense and in the same
2631 time in client we can use the same protocol routines for normal
2632 key exchange and to key agreement packet handling as well.
2634 * Added to both client's and server's KE protocol context the
2635 SilcSKEKeyMaterial pointer to save the key material. We will
2636 bring the key material to the protocol's final callback by doing
2637 this. The final callback must free the key material.
2639 * Added SKE's packet_send callback into client's KE protocol
2640 context so that the caller can choose what packet sending function
2641 is used. This way we can use different packet sending when
2642 doing normal SKE when doing key agreement packet handling (in
2643 the key agreement packet handling we do not want to encrypt
2646 * Implemented the responder side of the key agreement routines
2647 in the client. The client can now bind to specified port and
2648 accept incoming key negotiation. The key material is passed
2649 to the application after the protocol is over.
2651 * Implemented the processing of incoming Key Agreement packet
2652 in the client. Added function silc_client_key_agreement to
2655 * Implemented the intiator side of the key agreement routines
2656 in the client. The client can now initiate key agreement with
2657 another remote client. The key material is passed to the
2658 application after the protocol is over.
2660 * Created client_keyagr.c to include all the key agreement
2663 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2664 SILC_TASK_CALLBACK except that it is not static.
2666 * Created client_notify.c and moved the Notify packet handling
2667 from the client.[ch] into that file.
2669 * Created client_prvmsg.c and moved all private message and
2670 private message key routines from the client.[ch] into that file.
2672 * Create client_channel.c and moved all channel message and
2673 channel private key routines from the client.[ch] into that file.
2675 * Changed silc_client_get_client_by_id_resolve to resolve with
2676 WHOIS command instead of IDENTIFY command, in the file
2677 lib/silclient/idlist.c.
2679 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Implemented the SKE's responder side to the Client library.
2683 * When FAILURE is received to the protocol do not trust it
2684 blindly. Register a timeout to wait whether the remote closes
2685 the connection as it should do it, only after that process the
2686 actual failure. This was changed to both client and server.
2688 * Added client_internal.h to include some of the structures
2689 there instead of client.h in lib/silcclient/.
2691 * Added function silc_task_unregister_by_callback to unregister
2692 timeouts by the callback function.
2694 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Some "Incomplete WHOIS info" errors has been appearing on the
2697 log files. Took away the entry->userinfo check from WHOIS
2698 reply sending. The entry->userinfo is now " " if client did not
2699 provide one. I thought this was fixed earlier but something
2700 is wrong still. Let's see if the error still appears.
2702 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Fixed a minor bug in the login when the channel key is
2705 re-generated in the server. It used to generate the key in
2706 wrong order and thus caused problems in the channel traffic.
2708 * Fixed a minor bug in channel key distsribution after
2709 KICK command. The key was not sent to the router even though
2712 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Added silc_ske_process_key_material_data as generic routine
2715 to process any key material as the SILC protocol dictates. The
2716 function is used by the actual SKE library but can be used by
2717 applications as well. This relates to the private message keys
2718 and the channel private keys since they must be processed the
2719 same way the normal SILC session keys. The protocol dictates
2720 this. Affected files: lib/silcske/silcske.[ch].
2722 Added also silc_ske_free_key_material to free the
2723 SilcSKEKeyMaterial structure.
2725 * Defined silc_cipher_set_key function to set the key for
2726 cipher without using the object's method function. The affected
2727 files: lib/silccrypt/silccipher.[ch].
2729 * Implemented silc silc_client_add_private_message_key,
2730 silc_client_add_private_message_key_ske,
2731 silc_client_del_private_message_key,
2732 silc_client_list_private_message_keys and
2733 silc_client_free_private_message_keys functions in the
2736 Added functions silc_client_send_private_message_key to send
2737 the Private Message Key payload and silc_client_private_message_key
2738 to handle incoming Private Message Key payload.
2740 * Added Cipher field to the Private Message Key payload to set
2741 the cipher to be used. If ignored, the default cipher defined
2742 in the SILC protocol (aes-256-cbc) is used.
2744 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * Removed lib/silcclient/ops.h file.
2748 Redefined parts of the SILC Client Library API. Created new
2749 file silcapi.h that deprecates the ops.h file and defines the
2750 published Client Library API. Defined also private message key
2751 API and channel private key API into the file.
2753 This is the file that the application must include from the
2754 SILC Client Library. Other files need not be included by
2755 the application anymore.
2757 * Added new key_agreement client operation callback and also
2758 defined the Key Agreement library API for the application.
2760 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2763 is used by clients to request key negotiation between another
2764 client in the SILC network. If the negotiation is started it
2765 is performed using the SKE protocol. The result of the
2766 negotiation, the secret key material, can be used for example
2767 as private message key.
2769 Implemented the Key Agreement payload into the files
2770 lib/silccore/silauth.[ch].
2772 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Redefined ciphers for the SILC protocol. Added some new ciphers
2775 and defined the key lengths for the algorithms. Changed the
2776 code accordingly. The default key length is now 256 bits.
2778 * Fixed SKE key distribution function silc_ske_process_key_material
2779 when the key length is more than 128 bits. The default key
2780 length in SILC is now 256 bits.
2782 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2783 to indicate unsupported algorithm.
2785 * Renamed rijndael.c to aes.c and all functions as well.
2787 * Fixed a long standing channel key setting bug in client library.
2788 Weird that it has never surfaced before.
2790 * Fixed bug in channel deletion. If the entire channel is removed
2791 then it must also delete the references of the channel entry
2792 from the client's channel list as the client's channel entry and
2793 the channel's client entry share same memory.
2795 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Implemented CONNECT and SHUTDOWN commands in the client.
2799 * Implemented CLOSE command to the client.
2801 * Added the function silc_idlist_find_server_by_name into the
2802 files silcd/idlist.[ch].
2804 Added the function silc_idlist_find_server_by_conn into the
2805 files silcd/idlist.[ch].
2807 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * DIE command was renamed to SHUTDOWN. Updated the both code
2812 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2813 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2815 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2818 * Added function silc_server_create_connection function to create
2819 connection to remote router. My server implementation actually
2820 does not allow router to connect to normal server (it expects
2821 that normal server always initiates the connection to the router)
2822 so the CONNECT command is only good for connecting to another
2825 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2828 or some other client was kicked from the channel.
2830 Implemented the handling of the notify type to both client
2833 Implemented silc_server_send_notify_kicked to send the KICKED
2834 notify. It is used to send it to the server's primary router.
2836 * Implemented the KICK command into server and client.
2838 * Added `query' argument to the silc_idlist_get_client function
2839 to indicate whether to query the client from server or not if
2842 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2843 to indicate that the client is not channel founder.
2847 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2849 * Removed the rng context from SilcPacketContext structure and
2850 changed that the packet routine uses the Global RNG API.
2852 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Added support for quit message that client can "leave" on the
2855 channel when it quits the SILC. It is ditributed inside the
2856 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2858 Added silc_server_free_client_data that will take the
2859 signoff message as argument.
2861 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2863 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * Updated parts of the protocol specification to keep it up
2868 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2871 payloads in one packet.
2873 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2874 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2875 use now the new List flag.
2877 * Also deprecated the following packet types: REPLACE_ID,
2878 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2880 * Added list support for Notify packet in server.
2882 * Added silc_server_send_notify_channel_change to send the
2883 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2884 the silc_server_send_replace_id.
2886 * Added silc_server_send_notify_nick_change to send the
2887 NICK_CHANGE notify type. Deprecates the function
2888 silc_server_send_replace_id.
2890 * Added silc_server_send_notify_join to send the JOIN notify type.
2891 Deprecates the function silc_server_send_new_channel_user.
2893 * Added silc_server_send_notify_leave to send LEAVE notify type.
2894 Deprecates the function silc_server_send_remove_channel_user.
2896 * Added silc_server_send_notify_cmode and
2897 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2898 types. Deprecates the silc_server_send_set_mode function.
2900 * Added SERVER_SIGNOFF notify type to indicate that server has
2901 quit. This means that all clients on the channel from that
2902 server will drop. This can be also used when netsplit happens.
2904 Deprecated REMOVE_ID packet type since it is not needed anymore
2907 Added silc_server_send_notify_server_signoff to send the
2908 SERVER_SIGNOFF notify type. Deprecates the function
2909 silc_server_send_remove_id.
2911 Added also silc_server_send_notify_signoff to send the
2912 SIGNOFF notify type.
2914 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2915 SILC protocol from this day on. Changed the protocol
2916 specification as well.
2918 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2919 notify type. It is used between routers to notify about
2920 topic changes on a channel.
2922 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2925 * Partly updated the protocol specification to comply with the
2926 changes now made. It is still though a bit outdated.
2928 * The JOIN notify type now takes one extra argument <Channel ID>.
2929 The packet used to be destined to the channel but now the
2930 JOIN type may be sent as list thus it is impossible to
2931 destine it to any specific channel. By adding this argument
2932 it is again possible.
2934 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Added CREDITS file. The CHANGES and CREDITS file will appear
2937 in the distribution as well.
2939 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2942 types in the server's silcd/packet_receive.c.
2944 * Implemented CMODE and CUMODE to work in router environment.
2946 * Fixed minor encoding and decoding buglet from the
2947 lib/silccore/silcmode.c.
2949 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2952 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2954 * Changed all SilcConfigServer* and silc_config_server* to
2955 SilcServerConfig* and silc_server_config*, respectively.
2958 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2960 * Associated the ID (client or server ID) to the Authentication
2961 Payload to avoid any possibility of forging. Updated the
2962 protocol specification and the code accordingly.
2964 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * The RSA key length is now save to the RsaKey context in the
2967 key generation process in lib/silccrypt/rsa.c. The key length
2968 is now used to figure out the maximum size of the block allowed
2969 to be encrypted/signed.
2971 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2972 is equivalent to the silc_mp_mp2bin but does not allocate any
2975 * Changed silc_mp_mp2bin API to take length argument. If it is
2976 non-zero then the buffer is allocated that large. If zero, then
2977 the size is approximated using silc_mp_sizeinbase, which however
2980 * Created Global RNG API which is global RNG that application can
2981 initialize. After initializing, any routine anywhere in the
2982 code (including library) can use RNG without allocating a new
2983 RNG object. This was done to allow this sort of use of the
2984 RNG in code that has no chance to allocate RNG object. All
2985 applications currently allocate this and many routines in the
2986 library use this. Affected file lib/silccrypt/silcrng.[ch].
2988 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2989 it to use the Global RNG API.
2991 * Defined Authentication Payload into protocol specification that
2992 is used during SILC session to authenticate entities. It is
2993 used for example by client to authenticate itself to the server
2994 to obtain server operator privileges.
2996 Implemented this payload into the lib/silccore/silcauth.[ch].
2997 Implemented also routines for public key based authentication
2998 as the new protocol specification dictates.
3000 Moved definitions of different authentication methods from
3001 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3003 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3004 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3005 silc_pkcs_verify_with_hash functions into the file
3006 lib/silccrypt/silcpkcs.[ch].
3008 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3010 * The client entry's userinfo pointer must be always valid.
3011 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3012 will fail since it requires the userinfo. Now, the userinfo
3013 is allocated as "" if actual userinfo does not exist. Actually,
3014 it must exist and it is totally Ok to drop client connections
3015 that does not announce the userinfo. However, we will make
3016 this workaround for now.
3018 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3019 to return the remote port by socket.
3021 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3024 SILC_SERVER_PENDING_EXEC and added an new macro
3025 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3026 data or when error occurs while processing the pending command.
3028 Added new argument `destructor' into silc_server_command_pending
3029 and to the SilcServerCommandPending object. This destructor is
3030 now called after calling the pending callback or if error occurs
3031 immediately. If error occurs the actual pending callback won't
3032 be called at all - only the destructor. The destructor may be
3033 NULL if destructor is not needed.
3035 All this applies for client library code as well. Similar
3036 changes were made there as well for the pending commands.
3038 In the client, the application must now allocate the
3039 SilcClientCommandContext with the silc_client_command_alloc
3042 * Added reference counter to the SilcServerCommandContext. Added
3043 function silc_server_command_alloc and silc_server_command_dup
3046 Same type of functions added to the client library for the same
3049 * Removed the cmd_ident from IDListData away since it is now
3050 global for all connections. It is the command identifier used
3051 in command sending and with pending commands. The affected file
3054 * Added reference counter to the SilcSocketConnection objecet to
3055 indicate the usage count of the object. The object won't be
3056 freed untill the reference counter hits zero. Currently only
3057 server uses this, and client ignores it. The client must be
3058 set to use this too later. The affected files are
3059 lib/silccore/silcsockconn.[ch]. Added also the function
3060 silc_socket_dup to increase the reference counter.
3062 This was mainly added because it is possible that the socket
3063 is removed underneath of pending command or other async
3064 operation. Now it won't be free'd and proper DISCONNECTING
3065 flags, etc. can be set to avoid sending data to connection that
3066 is not valid anymore.
3068 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3069 the connection. After that it sets SILC_SET_DISCONNECTED.
3070 It is, however, possible that the socket data is not still freed.
3071 The silc_server_packet_process now checks that data is not
3072 read or written to connection that is DISCONNECTED. The socket
3073 get's freed when the reference counter hits zero.
3075 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Changed the client operation API: channel_message operation's
3078 `sender' is now the client entry of the sender, not the nickname
3079 and the `channel' is the channel entry, not the channel name.
3081 In the private_message operation the `sender' is now also the
3082 client entry of the sender not the nickname.
3084 Affected file is lib/silcclient/ops.h and all applications
3085 using the client operations.
3087 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Moved the calling of ops->connect() from connect_to_server_final
3090 into receive_new_id functin since that is the point when the
3091 client is actually allowed to send traffic to network. The
3092 affected file is lib/silcclient/client.c.
3094 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3097 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3098 (if needs broadcasting) instead of broadcasting the packets one
3099 by one which would make a burst in the network traffic.
3101 * Added `broadcast' argument to the functions in silcd/server.[ch]
3102 silc_server_create_new_channel[_with_id] to indicate whether
3103 to send New Channel packet to primary router.
3105 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Added new function into the silcd/server.[ch] files:
3108 silc_server_create_new_channel_with_id to create new channel with
3109 already existing Channel ID.
3111 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3112 lib/silccore/silcpacket.h. This packet is used t send list of
3113 Set Mode payloads inside one packet. Server uses this to set
3114 the modes for the channels and clients on those channels, that it
3115 announced to the router when it connected to it. The protocol
3116 specification has been updated accordingly.
3118 * The silc_server_new_channel did not handle the packet coming
3119 from normal server as it normally does not send that. However,
3120 when it announces its channels it does send it. Implemented
3121 the support for that.
3123 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3124 into the file lib/silccore/id.h.
3126 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Fixed memory leaks in the functions silc_idlist_del_client,
3129 silc_idlist_del_channel and silc_idlist_del_server in the file
3130 silcd/idlist.c. All of those leaked like a sieve.
3132 * Fixed some small memory leaks in the client's function
3133 silc_client_notify_by_server.
3135 * Added functions into silcd/server.c: silc_server_announce_clients,
3136 silc_server_announce_channels and silc_server_announce_server.
3137 These functions are used by normal and router server to announce
3138 to its primary router about clients, channels and servers (when
3139 router) that we own. This is done after we've connected to the
3142 These functions effectively implements the following packet types:
3143 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3144 and SILC_PACKET_NEW_ID_LIST.
3146 * Added new functions into the silcd/packet_receive.[ch]:
3147 silc_server_new_id_list, silc_server_new_channel_list and
3148 silc_server_new_channel_user_list to handle the incoming
3149 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3151 * Added support of changing Channel ID in the function
3152 silc_server_replace_id. If the server that announces a channel
3153 to the router already exists in the router (with same name but
3154 with different Channel ID), router is responsible to send
3155 Replace ID packet to the server and force the server to change
3156 the Channel ID to the one router has.
3158 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3159 client that the Channel ID has been changed by the router. The
3160 normal server sends this to the client. Client must start using
3161 the new Channel ID as the channel's ID.
3163 Implemented handling of this new type into lib/silcclient/client.c
3164 into the function silc_client_notify_by_server.
3166 * Added new function silc_idlist_replace_channel_id into the files
3167 silcd/idlist.[ch] to replace the Channel ID.
3169 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Call silc_server_command_identify_check always when processing
3172 the IDENTIFY command in silcd/command.c
3174 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3177 send keepalive packets. The packet can be sent by clients,
3178 servers and routers.
3180 Added function silc_socket_set_heartbeat into the file
3181 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3182 If not set, the heartbeat is not performed. The actual
3183 heartbeat is implemented in the low level socket connection
3184 library. However, application is responsible of actually
3187 Added silc_server_send_heartbeat to send the actual heartbeat
3188 packet into silcd/packet_send.[ch]. Server now performs
3189 keepalive with all connections.
3191 * Added silc_task_get_first function into lib/silcutil/silctask.c
3192 to return the timeout task with shortest timeout. There was a bug
3193 in task unregistration that caused problems. TODO has been
3194 updated to include that task system must be rewritten.
3196 * The client library will now resolve the client information when
3197 receiving JOIN notify from server for client that we know but
3198 have incomplete information.
3200 * Rewrote parts of silc_server_remove_from_channels and
3201 silc_server_remove_from_one_channel as they did not remove the
3202 channel in some circumstances even though they should've.
3204 * Encryption problem encountered in server:
3206 The LEAVE command used to send the Channel Key packet to the
3207 router immediately after generating it. However, the code
3208 had earlier sent Remove Channel user packet but not immediately,
3209 ie. it was put to queue. The order of packets in the router
3210 was that Channel Key packet was first and Remove Channel User
3211 packet was second, even though they were encrypted in the
3212 reverse order. For this reason, MAC check failed. Now, this
3213 is fixed by not sending the Channel Key packet immediately but
3214 putting it to queue. However, this is more fundamental problem:
3215 packets that are in queue should actually not be encrypted
3216 because packets that are sent immediately gets encrypted
3217 actually with wrong IV (and thus MAC check fails). So, packets
3218 that are in queue should be encrypted when they are sent to
3219 the wire and not when they put to the queue.
3221 However, the problem is that the current system has not been
3222 designed to work that way. Instead, the packet is encrypted
3223 as soon as possible and left to the queue. The queue is then
3224 just purged into wire. There won't be any fixes for this
3225 any time soon. So, the current semantic for packet sending
3228 o If you send packet to remote host and do not force the send
3229 (the packet will be in queue) then all subsequent packets to the
3230 same remote host must also be put to the queue. Only after the
3231 queue has been purged is it safe again to force the packet
3234 o If you send all packets immediately then it safe to send
3235 any of subsequent packets through the queue, however, after
3236 the first packet is put to queue then any subsequent packets
3237 must also be put to the queue.
3239 Follow these rules and everything works fine.
3241 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Added new function silc_server_remove_clients_by_server to
3244 remove all client entries from ID list when the server connection
3245 is lost. In this case it is also important to invalidate all
3246 client entires as they hold the invalid server entry. This
3247 fixes fatal bug when server has lost connection and will reconnect
3250 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Made some sanity checks to silc_server_daemonise like to check
3253 whether the requested user and group actually exists.
3255 * Added sanity check to SKE's silc_ske_responder_finish to check
3256 that the public and private key actually is valid.
3258 * Invalidate the client's nickname when receiving Replace ID
3259 packet and the Client ID is being replaced. This means that the
3260 server will query the nickname if someone needs it (client)
3263 * Sort the ID Cache in client library when the ID Cache data
3264 has changed (needs sorting).
3266 * Do not allow for SILC client to create several connections to
3267 several servers. The client does not support windows right now
3268 and generating multiple connections causes weird behaviour.
3270 Irssi-silc client does support windows and can handle several
3271 connections without problems, see: www.irssi.org and SILC plugin.
3273 * Fixed some places where client was added to the IDList. The
3274 rule of thumb is following (in order to get everything right):
3275 If the client is directly connected local client then the
3276 `connection' argument must be set and `router' argument must be
3277 NULL to silc_idlist_add_client function. If the client is not
3278 directly connected client then the `router' argument must
3279 bet set and the `connection' argument must be NULL to the
3280 silc_idlist_add_client function.
3282 * The funtion silc_server_packet_send_local_channel actually did
3283 not check whether the client was locally connected or not. It
3284 does that now. Fixed a bug related to LEAVE command.
3286 * Fixed Remove Channel User payload parsing bug in server's
3287 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3289 * The server's silc_server_save_channel_key now checks also the
3290 global ID list for the channel as it might not be in the local
3291 list. Fixed a bug related to LEAVE command.
3293 * Is this the end of the [<unknown>] buglet that has been lurking
3294 around for a long time? A little for loop fix in server's
3295 silc_server_command_whois_parse that is used by both IDENTIFY
3296 and WHOIS command. At least, this was a clear bug and a cause
3297 of one type of [<unknown>] buglet.
3299 * WHOIS and IDENTIFY commands call the function
3300 silc_server_command_[whois/identify]_check function even if
3301 we are not router server.
3303 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Added --with-gmp configuration option. If set the GMP
3306 is always compiled in the SILC source tree. If not set then
3307 it is checked whether the system has the GMP3 installed. If
3308 it has then the GMP won't be compiled (the system's headers
3309 and library is used), if it doesn't have it then the GMP is
3310 compiled in the SILC source tree.
3312 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Changed RSA private exponent generation to what PKCS #1
3315 suggests. We try to find the smallest possible d by doing
3316 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3317 not security fix but optimization.
3319 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Added new config entry [Identity] to fork the server and run
3322 it as specific user and group. A patch from Bostik.
3324 * Imported Dotconf configuration library into lib/dotconf.
3325 This will be used to create the SILC configuration files later.
3326 It will appear in the distsribution after this commit.
3328 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * A big code auditing weekend happening. Auditing code for
3331 obvious mistakes, bugs and errors. Also, removing any code
3334 Removed files for being obsolete:
3336 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3337 inline in the file lib/silcutil/silcbuffer.h)
3339 o lib/silcutil/silcbufutil.c (the header has inline versions)
3341 Changed code to fix possible error conditions:
3343 o The buffer formatting routines now check that the destination
3344 buffer really has enough space to add the data. This applies for
3345 both buffer formatting and unformatting
3346 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3347 unformatting was changed to accomodate following rules:
3348 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3349 sent to the function while XXX_*STRING will not allocate or copy
3350 the data into the buffer. Instead it sets the pointer from the
3351 buffer into the pointer sent as argument (XXX_*STRING used to
3352 require that the pointer must be allocated already). This change
3353 makes this whole thing a bit more consistent and more optimized
3354 (note that the data returned in the unformatting with XXX_*STRING
3355 must not be freed now). The routines return now -1 on error.
3357 o Tried to find all code that use buffer_format and buffer_unformat
3358 and added return value checking to prevent formatting and
3359 especially unformatting errors and possible subsequent fatal
3362 o Changed ske->x and ske->KEY to mallocated pointers in
3363 lib/silcske/silcske.h. Fixed possible data and memory leak.
3365 o Added return value checking to all *_parse* functions. Fixed
3366 many memory leaks as well.
3368 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3369 so that buffer overflows would not happen. All code now also
3370 checks the return value as it can fail.
3372 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Added reconnection support to server if the normal server looses
3375 its connection to the router (for example if router is rebooted).
3376 The server performs normal reconnection strategy implemented
3377 to the server. Affected file silcd/server.c.
3379 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Added new packet type SILC_PACKET_SET_MODE that is used to
3382 distribute the information about changed modes (for clients,
3383 channels and clients channel modes) to all routers in the
3384 network. Updated the protocol specification accordingly.
3386 Added functions into silcd/packet_send.c and
3387 silcd/packet_receive.c: silc_server_send_set_mode,
3388 silc_server_set_mode.
3390 Added new files silcmode.[ch] into lib/silccore that implements
3391 the encoding and decoding of Set Mode Payload. Added new type
3392 SilcSetModePayload. Moved the definitions of different modes
3393 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3395 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Oops, a little mistake in server's connection authentication
3398 protocol. The protocol is not ended with FAILURE but with
3399 SUCCESS if the authentication is Ok. :) Affected file is
3402 * Implemented NICK_CHANGE notify handling in server in the file
3403 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3404 the local clients on the channel. After the changing nickname
3405 in router environment snhould work and the [<unknown>] nickname
3406 should appear no more.
3408 The silc_server_replace_id function that receives the Replace ID
3409 payload now sends the NICK_CHANGE notify type also in the file
3410 silcd/packet_receive.c
3412 * Changed WHOIS and IDENTIFY command to support the maximum amount
3413 of arguments defined in protocol specs (3328 arguments). This
3414 fixed a bug that caused problems when there were more than three
3417 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Added extra parameter, command identifier, to the
3420 silc_client_send_command so that explicit command identifier
3423 Changed that ID list routines uses specific command identifier
3424 when sending WHOIS/IDENTIFY requests to the server so that they
3425 can be identified when the reply comes back.
3427 Affected files lib/silcclient/command.[ch],
3428 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3430 * Added `sender' argument to silc_server_packet_send_to_channel
3431 to indicaet the sender who originally sent the packet to us
3432 that we are now re-sending. Ignored if NULL. Affected file
3433 silcd/packet_send.[ch].
3435 * Added some server statistics support in silcd/server_internal.h
3436 SilcServerStatistics structure and around the server code. Also
3437 send some nice statistics information when client is connecting
3440 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Fixed channel ID decoding in server's JOIN command reply in
3443 silcd/command_reply.c
3445 * Fixed braodcasting of replace ID payload to not to send it if
3446 we are standalone server in silcd/packet_receive.c.
3448 * Fixed all channel message sending routines to not to send
3449 packets to clients that has router set, since they are routed
3450 separately in the same function earlier. Affects file
3451 silcd/packet_send.c and all channel packet sending functions.
3453 * In USERS reply, res_argv[i] are not allocated, the table
3454 is allocated. Thus changed that free the table, not its
3457 * In server's whois_check and identify_check if the client is
3458 locally connected do not send any WHOIS commands - they are not
3461 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Fixed some minor bugs in client when sending WHOIS command. The
3464 arguments was in wrong order.
3466 * Removed statis function add_to_channel from server in
3467 silcd/command.c that was previously used with the joining but
3470 * Tested USERS command in router environment successfully with two
3471 routers, two servers and two clients.
3473 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Reorganized the USERS command and command reply in client library
3476 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3477 When the command is given by user we register a pending command
3478 callback that will reprocess the command after the reply has been
3479 received from the server. When reprocessing the packet we then
3480 display the information. Thus, the USERS information is displayed
3481 now in the command callback instead of in the command reply
3482 callback. The processing of the command is same as previously
3483 when server has sent the command reply in the JOINing process.
3485 * Added to USERS command in silcd/command_reply.c to join the client,
3486 we didn't use to know about, to the channel after we've created
3487 a client entry for it. Also, for clienet we did know already still
3488 check whether it is on the channel or not and add it if not.
3490 * Removed silc_server_command_join_notify as the function and its
3493 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Changed the client's pending command handling to the same as the
3496 server's pending command handling. It is also now possible to
3497 execute command reply functions from other command reply
3498 function as the function callbacks for commands and command
3499 replies are one and same. The pending commands are not static
3500 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3501 in client connection context. Thus, pending commands are server
3502 connection specific as it is convenient.
3504 Changed the function silc_client_command_pending and
3505 silc_client_command_pending_del and added new function
3506 silc_client_command_pending_check. Removed the
3507 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3510 * Added cmd_ident, current command identifier, to the client
3511 connection context in lib/silcclient/client.h to keep track on
3512 command identifiers used in command sending. Client's command reply
3513 function handling now supports the mandatory command identifiers.
3515 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3516 funtions in client to fully support pending command callbacks.
3518 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3519 as one of the arguments to the application in the command reply
3522 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3523 before first releasing SILC but came back. Now it is removed again
3524 and should come back nomore. The FORWARDED flag was used only
3525 by the JOINing procedure by forwarding the command packet to router.
3526 Now, the JOINing procedure has been changed to more generic (due
3527 to various router environment issues) and FORWARDED is not needed
3528 anymore for anything. The protocol specification is yet to be
3531 Now, removed silc_server_packet_forward from server and the flag
3532 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3534 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Renamed NAMES command to USERS command. The NAMES was named that
3537 due to historical reasons. Now it is renamed. Also, rewrote
3538 parts of the USERS command. The nickname list is not sent anymore
3539 by the server. Only Client ID and mode lists are sent in the USERS
3540 command. Changed this also to the protocol specification.
3542 The client now resolves the names and stuff after it receives
3543 the USERS list from the server when joining to the channel.
3545 * WHOIS and IDENTIFY commands has been changed to support multiple
3546 Client ID's per command. One can now search for multiple users
3547 in the network by sending only one WHOIS or IDENTIFY command.
3548 Changed the code and the protocol specifications.
3550 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3551 uses silc_server_command_whois_parse to parse the request. */
3553 * If normal server, do not parse the WHOIS and IDENTIFY requests
3554 before sending it to the router. Saves some time.
3556 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Fixed JOIN command on client library. Wrong number of arguments
3559 used to crash the client.
3561 * Added silc_server_channel_has_global function to check whether
3562 channel has global users or not.
3564 * Added silc_server_channel_has_local function to check whether channel
3565 has locally connected clients on the channel.
3567 * The silc_server_remove_from_one_channel now checks whether the
3568 channel has global users or not after given client was removed from
3569 the channel. It also checks whether the channel has local clients
3570 on the channel anymore. If it does not have then the channel entry
3571 is removed as it is not needed anymore.
3573 * The silc_server_notify now checks on JOIN notify whether the joining
3574 client is one of locally connected or global. If it is global then
3575 the channel has now global users on the channel and that is marked
3576 to the channel entry. Also, it now saves the global client to
3577 global list who is joining and JOINs it to the channel. This is
3578 for normal server, that is.
3580 Changed silc_server_send_notify_on_channel,
3581 silc_server_packet_relay_to_channel and
3582 silc_server_packet_send_to_channel check if we are normal server
3583 and client has router set (ie. global client) do not send the
3584 message to that client, as it is already routed to our router.
3586 * Implemented LEAVE notify type handling in silc_server_notify
3589 * Tested LEAVE command in router environment successfully. Tested
3590 with two routers, two servers and two clients.
3594 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3596 * Implemented SIGNOFF notify type handling in silc_server_notify
3599 * silc_server_remove_id now removes the client entry from all channels
3600 it has joined and thusly sends SIGNOFF notify type.
3602 * Rewrote the NAMES list generation in server by removing two excess
3603 loops. The lists are created now inside one loop.
3605 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * silc_server_remove_channel_user checks now also global list
3608 for channel and client.
3610 * silc_server_new_channel_user checks now both local and global
3611 list for channel and client. Fixed a bug in client id decoding.
3612 Used to decode wrong buffer.
3614 * silc_server_channel_message checks now both local and global
3615 list for channel entry.
3617 * Tested channel joining (hence JOIN) in router environment
3618 successfully. Tested with two routers, two servers and two
3621 * Tested channel message sending in router environment successfully.
3623 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Added silc_server_save_channel_key into server.[ch] to save the
3626 received channel key in Channel Key payload processing. It is
3627 also used in JOIN command reply handling.
3629 Equivalent function silc_client_save_channel_key added into
3630 client.[ch] into client library.
3632 * Changed JOIN command reply to send information whether the channel
3633 was created or not (is existing already) and the channel key
3634 payload. Changed protocol specs accordingly.
3636 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3637 the request was sent by ID and not by nickname. Crashed on
3640 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3643 now correctly save the received data.
3645 * silc_server_free_sock_user_data now notifies routers in the
3646 network about entities leaving the network.
3648 At the same time implemented functions silc_server_remove_id
3649 and silc_server_send_remove_id to receive and send REMOVE_ID
3650 packets. The packet is used to notify routers in the network
3651 about leaving entities. The ID removed will become invalid in
3654 * Added function silc_idlist_del_server into server. Removes and
3655 free's server entry from ID list.
3657 * silc_server_private_message function now checks, if we are router,
3658 that the destination ID really is valid ID, naturally.
3660 * In router when NEW_ID packet is received (for new client) the
3661 hash of the Client ID is saved in the ID Cache but the
3662 client->nickname is set to NULL, instead of putting the hash
3665 IDENTIFY command now also checks that client->nickname must be
3666 valid. If it is not if will request the data from the server who
3667 owns the client. Added new function
3668 silc_server_command_identify_check.
3670 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3671 to set the command to already allocated Command Payload.
3673 * Tested private message sending in router environment with two
3674 routers, two servers and two clients. Fixed minor bugs and now
3677 * Fixed segfault from client's NAMES command. Used to crash if
3680 * Forwarded packets must not be routed even if it is not destined
3681 to the receiver. Changed server code comply with this.
3683 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Added `require_reverse_mapping' boolean value to ServerParams
3686 structure. If TRUE (not default) the server will require that
3687 the connecting host has fully qualified domain name.
3689 If the reverse mapping is not required and hostname could not be
3690 found the IP address is used as hostname.
3692 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Implemented version string checking to both client and server.
3695 The check is incomplete currently due to the abnormal version
3696 strings used in development version of SILC.
3698 * Changed all command functions in server to use the new
3701 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Changed char *data to unsigned char *data in ID Cache system to
3704 support binary data as ID Cache data. Changed code to support
3705 binary data in lib/silccore/idcache.c.
3707 * Renamed silc_server_packet_relay_command_reply to
3708 silc_server_command_reply as it is normal packet receiving
3709 function. Rewrote the function to accept command replys for
3710 servers and not only for clients.
3712 * Mark remote router always as registered server if we are connecting
3713 to it. Otherwise, commands sent by the router to us are ignored.
3715 * All ID List find routines now returns the ID Cache Entry pointer
3716 as well if requested.
3718 * WHOIS command works now in router environment, tested with two
3719 routers, two servers and two clients.
3721 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3722 in router environment (as it is almost equivalent to WHOIS) but
3723 hasn't been tested thoroughly. Added new functions:
3725 silc_server_command_identify_parse
3726 silc_server_command_identify_send_reply
3727 silc_server_command_identify_from_client
3728 silc_server_command_identify_from_server
3730 * Disabled route cache adding because adding two different ID's with
3731 same IP replaces the old cache entry thus giving wrong route.
3732 The entry->router->connection is always the fastest route anyway
3733 so route cache may not be needed. Of course, new routes maybe
3734 established after receiving the ID when the entry->router->connection
3735 might not be anymore the most optimal.
3737 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Add route cache for received ID for fast routing.
3741 * Added silc_server_packet_route to route received packet on router
3742 that is not destined to us.
3744 * Renamed silc_server_get_route to silc_server_route_get.
3746 * Added id_string and id_string_len fields into SilcServer to
3747 include encoded ServerID for fast comparing without excess
3748 encoding of the ID's.
3750 * Cleaned up WHOIS command on server side. Added following static
3753 silc_server_command_whois_parse
3754 silc_server_command_whois_check
3755 silc_server_command_whois_send_reply
3756 silc_server_command_whois_from_client
3757 silc_server_command_whois_from_server
3759 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3760 arguments in command replies. All command functions should be
3761 updated to use this macro.
3763 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Minor typo fixes on command reply handling on server.
3767 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Added silc_server_command_add_to_channel internal routine to add
3770 the client to the channel after router has created the channel and
3771 sent command reply to the server.
3773 * Added generic silc_server_send_command to send any command from
3776 * Use static buffer with ID rendering instead of duplicating data.
3778 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Fixed a channel user mode bug when joining to a channel server gave
3781 everybody channel founder rights, oops.
3783 * We mark ourselves as the router of the incoming server connection
3784 if we are router ourselves. This way we can check in some packet
3785 sending functions whether it is locally connected server. For
3786 incoming router connections we put NULL.
3788 * For router sending packets locally means now always sending the
3789 packet cell wide; to local clients and local servers. For normal
3790 server sending packet locally means sending it to only local
3793 * Fixed the JOIN command to really work in router environment. If the
3794 channel is created it is always created by the router. Router is
3795 also responsible of making the initial joining to the channel,
3796 sending JOIN notify to the sending server and distributing
3797 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3798 does not exist server doesn't do anything else but forward the
3799 command to the router which performs everything.
3801 * Added silc_server_send_channel_key function to send the Channel Key
3804 * Added silc_server_create_channel_key to create new channel key. The
3805 channel key is now re-generated everytime someone joins or leaves
3806 a channel, as protocol dictates. Note: channel->key_len is the
3809 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3812 packet_receive.[ch] to separate packet sending and receiving
3813 routines. The server.[ch] now includes everything else including
3814 actual packet processing (writing and reading data) and other
3817 Renamed silc_server_private_message_send_internal to
3818 silc_server_send_private_message. The routine is still though
3819 used only to relay private messages as server does not send
3820 private messages itself.
3822 Renamed silc_server_new_channel to silc_server_create_new_channel
3823 and added new function sicl_server_new_channel that handles the
3824 incoming New Channel packet. Added also new sending function
3825 silc_server_send_new_channel to send New Channel Payload.
3827 * Added new function silc_server_notify to process incoming notify
3828 packet to the server/router. Server may then relay the notify
3829 to clients if needed.
3831 * Added new function silc_server_new_channel_user to process incoming
3832 New Channel User packet. Router will redistribute the packet and
3833 send JOIN notify to its local clients and locally connected servers
3834 if needed. Normal server will send JOIN notify to its local client
3835 on same channel when received this packet. Added also corresponding
3836 sending function silc_server_send_new_channel_user to sent the
3839 * Added boolean route argument to send_notif_to_channel and
3840 packet_send_to_channel functions to attempt to route the packet
3841 if it is TRUE and send only locally if it is FALSE.
3843 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * silc_server_replace_id now broadcasts the received replace ID
3846 packet if it is not broadcast packet already. The router must
3847 broadcast to inform other routers about changed ID.
3849 * Added backpointer to server's router into SilcServer context in
3850 silcd/server_internal.h.
3852 * Fixed silc_server_packet_broadcast to send correct broadcast
3855 * The channel key is now distributed to the local client as soon
3856 as it is received from the router (in router environment) so that
3857 no other packet may be sent for the channel until client has
3860 * silc_server_remove_channel_user now broadcasts the received
3861 Remove Channel User packet if it is not broadcast packet already.
3862 The router must broadcast to inform other routers about removed
3865 * Added users field into SilcPacketContext that is a reference count
3866 of the context. One can increase the reference count by calling
3867 silc_packet_context_dup which is now changed to just increase the
3868 reference count instead of duplicating the data. The reference
3869 count is decresed by calling silc_packet_context_free that will
3870 free the data after the reference count hits zero.
3872 For now on the packet context and everything allocated into it
3873 (including the raw packet from network) must be freed by calling
3874 the new silc_packet_context_free function. Added also new function
3875 silc_packet_context_alloc that must be used now to allocate the
3876 context. This also means that if a routine is asynchronous from
3877 silc_[client/server]_packet_parse_type the packet context must
3878 be duplicated by calling silc_packet_context_dup. Otherwise it
3879 gets free'd after silc_[client/server]_packet_parse_type returns.
3880 Also, one must remember that if packet is duplicated then its
3881 reference count must be decresed by calling the free function as
3882 many times as it was duplicated.
3884 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3885 from both client and server.
3887 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Made joining to a channel working in router environment.
3891 * Cleaned up JOIN command on server side and create function
3892 silc_server_command_join_channel internal routine to make the
3895 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Changed silc_command_pending list to SilcDList. Also, added
3898 `ident' field to SilcServerCommandPending structure to identify
3899 the reply and to call correct callback.
3901 Added silc_server_command_pending_check function to replace the
3902 corresnponding macro. The silc_command_pending list is not
3905 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3906 to set identifier to previously allocated Command Payload. It
3907 is used to set identifier for command when resending Command
3910 * Added silc_command_payload_encode_payload to encode Command
3911 Payload buffer from SilcCommandPayload structure.
3913 * Added silc_argument_payload_encode_payload to encode Argument
3914 payload buffer from SilcArgumentPayload structure.
3916 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Changed WHOIS command to support router connection on server side.
3919 The whois request is always sent to router unless the server is
3920 standalone server. After server has received the reply from the
3921 router will it send the reply to the client.
3923 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3924 broadcast received broadcast packet. The function is used only
3925 by router. The broadcast packet is always sent to the router's
3928 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3929 render given ID to printable string, for log files for example.
3931 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Made basic router to router connections working. At least they
3934 can now connect to each other but nothing really works the way
3935 they are supposed - yet.
3937 * Added new initiator token to RouterConnection configuration
3938 file in silcd/serverconfig.[ch]. It is used to tell whether we
3939 are the initiator to the remote router or whether we'll expect
3940 the other end to connect.
3942 * Moved registering of listener task to silc_server_init, hence
3943 the server starts listenning as soon as it is run, even if it
3944 does not have connections to other routers. Let's see how well
3947 * Changed default connection retry timeouts for more suitable in
3950 * Removed cipher and such arguments from silc_idlist_add_client
3951 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3952 Added new function silc_idlist_add_data to add the keys and stuff
3955 * Added SilcIDListData structure and added it to SilcClientEntry
3956 and SilcServerEntry as their first field in the structure. This
3957 way we can explicitly cast the ID entries to the SilcIDListData
3958 structure and get common data for the entries. In past, we had
3959 to first check what type of connection it is and then cast it to
3960 correct ID entry type. Now, we can directly cast the opaque
3961 pointer to the SilcIDListData (no matter what ID entry it actually
3962 is) and get the data needed.
3964 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3967 in some circumstances even if threre were timeout tasks, though not
3968 IO tasks, but tasks anyway. Now fixed.
3970 * Defined SilcServerConnection structure to hold connection specific
3971 stuff about directly connected servers and routers. The definition
3972 is currently in silcd/server_internal.h. I thought about having
3973 a bit more important role fro this struct but for now it is used
3974 only when connecting to other server (or router actually).
3976 * Added connecting retry support in server when connecting to
3977 router(s). The retry feature implement exponential backoff
3978 algorithm. Also, added SilcServerParams structure to hold default
3979 parameters for server. For now, it include these retry settings
3980 and are hard coded. After server is moded to be as Silc Server
3981 Library this structure will be more important.
3983 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Changed client librarys channel->clients table to SilcList and
3986 changed code accordingly.
3988 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Changed client's channel table to SilcList and changed code
3991 accordingly. Also changed SilcChannelClientEntry to include back-
3992 pointer to the channel so that client entry can use that structure
3993 as list as well and we have fast cross-reference to the channel.
3994 This change dramatically decreased the complexity of channel
3995 handling with client entry and vice versa (removed one extra
3996 loop when searching for channel entry from many functions).
3998 * Changed server->sim from table to SilcDList and changed code
4001 * NAMES command can now be used from user interface. It will show
4002 the user list on the channel, neatly.
4004 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4005 Code now saves realname of the user if it becomes available.
4007 * Renamed configure.in to configure.in.pre and made ./prepare
4008 script to automatically add correct version string to
4009 configure.in which it creates from configure.in.pre.
4011 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * NAMES command reply now shows users mode with the nickname when
4016 * Moved silc_client_ch[u]mode[_char] functions from
4017 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4018 place sucks, they are utility functions and should be in some
4021 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4023 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4026 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Added TRQ (efficient deque and list library) into lib/trq. This is
4031 a very good list library that is currently used in the SILC. Defined
4032 SilcList API over the library because I didn't like the API very
4033 much. See lib/trq/silclist.h for the API and examples of how to
4034 use the API. Fixed various places in the code to use the new
4035 SilcList API. The SilcList is meant for lists that has a structure
4036 already defined as a list. It is not suitable to add just some
4037 context to the list (in TRQ, the context is the list actually).
4039 So, I defined SilcDList that can be used for the purpose where
4040 predefined list structure does not exit. This can be used as
4041 such list. Now some context just can be added to the SilcDList.
4042 Currently this list is not used in the SILC just yet, though there
4043 are a lot places where this can replace dynamically allocated
4044 tables and I will fix these places, later, to use SilcDList.
4045 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4046 and use TRQ internally).
4048 Also fixed some annoying warning messages that the original TRQ
4049 code generated. Also minor changes to TRQ's Makefile.in.
4051 * Added support for querying by Client ID to both WHOIS and
4052 IDENTIFY commands into server, as required by the protocol.
4054 * Removed method function pointers from SilcBuffer structure. They
4055 weren't used to anything and just increased the context size for
4056 no good reason. This change also made silc_buffer_alloc and
4057 silc_buffer_free functions inline functions.
4059 * Disabled command flooding detection support until it's fixed so
4060 that it accepts commands in but does not execute them more than once
4063 * Added silc_net_localhost(), to return local hostname, into
4064 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4065 that must be initialized before calling silc_client_init.
4067 * Added new function: silc_server_send_notify_on_channels to send
4068 notify messages to all channels client has joined. It is assured
4069 that the message is sent only once per client.
4071 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4072 lib/silcutil/silcutil.[ch] as silc_format function. The new
4073 function is generic and is used by server as well, not only by
4074 the logging routines.
4076 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4077 the provided version string was not acceptable. Added new function:
4078 silc_ske_check_version into lib/silcske/silcske.h. The function
4079 must be implemented by the application (client or server) and it
4080 does not reside in the SKE library. The function checks the version
4081 string remote end sent.
4083 * Added back pointers (to opaque context and to SilcSocketConnection)
4084 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4086 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4087 duplicate packet context structure.
4089 * Changed `notify' client operation to send same arguments as client
4090 receives from server except for ID's. ID's are mapped to correct
4091 ID entry and that is returned. Also, if channel entry is not sent
4092 by server but the notify is for channel the channel entry is sent
4093 to application (otherwise application doesn't know that it is for
4094 channel (library gets it from packet's Destination ID)).
4096 * Added silc_client_remove_from_channels into client library to
4097 remove a client from all channels it has joined to. Used when
4098 received SIGNOFF notify from server. Added also new function
4099 silc_client_replace_from_channels to replace old ID entry with
4100 new ID entry on all channels. Used when received NICK_CHANGE
4103 * Fixed ID Cache list handling in silc_idlist_get_client in
4104 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4105 to get (or query) client by ID.
4107 * Updated TODO list.
4109 * Added connection authentication status message defined by the
4110 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4111 support for these into the code in client and server side.
4113 * Added generic function silc_client_send_command to send any command
4114 with variable argument list. Application should use this function
4115 to send commands if the command functions provided by the library
4116 does not suite for the application's user interface needs.
4118 * Added new `failure' client operation. Application is notified about
4119 received failure packet if client is executing a protocol. In this
4120 case the protocol's execution has failed.
4122 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4123 is required by the protocol.
4125 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4126 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4129 * Added status flag to SilcSKE object to indicate realtime status
4130 of the SKE protocol.
4132 * Application receives now exactly same command reply arguments as
4133 the library receives from server. However, if ID is received the
4134 corresponding ID entry is returned to the application (eg. Client
4135 ID is mapped to correct SilcClientEntry entry and that is returned).
4136 Changed command_reply client operation due to this change.
4138 * Changed all ID's in commands and in command replys as ID Payloads.
4139 Change affected both client and server side codes.
4141 All ID's sent in SILC network (with execption of ID's in SILC
4142 Packet header) are sent in ID Payload to support variable length
4145 * Server now notifies nick changes and notifies all clients on
4146 the channels about the new nickname (about the new Client ID,
4149 * Implemented CMODE command to change channel modes. Supports all
4150 channel modes defined by the protocol specs except ban and invite
4151 lists. (Also, private channel key mode is supported but support for
4152 setting private channel key in client is missing, thus, this mode
4153 has no effect on client side (except that server requires that the
4154 client uses private channel key and normal channel traffic does not
4157 Also, invite mode works per se, but INVITE command does not work
4158 yet correctly, so you can set channel as invite only channel but
4159 inviting clients to the channel does not work (it is yet to be
4160 thought what's the best way to do it).
4162 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4163 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4164 Implemented CUMODE command to change user's mode on the channel.
4165 Supports all modes defined by the protocol specs.
4167 * Added NAMES command reply to return users modes on the channel.
4169 * Removed unnecessary and slow ciphers from lib/silccrypt.
4171 * Set SO_KEEPALIVE option to connection sockets by default.
4173 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4175 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4176 redefined the Notify Payload into protocol specs.
4178 * Added silc_id_payload_parse_id to get ID directly from raw
4181 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4184 accept searching by Client ID as well.
4186 * Added support for LEAVE and SIGNOFF notify types in client library.
4188 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4189 to parse ID Payload from raw data.
4191 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Added flags parameter into silc_ske_assemble_security_properties
4194 function in lib/silcske/silcske.[ch].
4196 * Changed notify client operation to fit better for notify messages
4197 sent by server. The notify payload received from server is now
4198 passed to the application (after parsing it to SilcNotifyPayload).
4199 It is application's responsibility to retrieve the arguments
4200 from the payload and show the message the way it wants. The message
4201 sent by server is implementation specific.
4203 * Changed public keys to comply with the protocol specification.
4204 Old public keys are not supported anymore and are not compatible.
4206 * Removed nickname from Channel Payload as the latest draft removed
4207 it. The client must resolve the nickname from the NAMES command
4208 reply received when it joined the channel.
4210 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4212 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Fixed some errors in protocol specification drafts.
4216 * Created lib/silccore/silcnotify.c to implement Notify Payload
4217 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4218 generic payloads described by protocol specifications. The file
4219 includes implementations for ID Payload and Argument Payload.
4221 * Changed Command Payload implementation to use the new Argument
4222 Payload. Changed command_xxxx_payload to command_payload_xxxx
4223 to comply with SILC coding conventions.
4225 * Added suppport for Argument Payload handling in Notify Payload
4226 implementation as protocol requires it. Added the new support
4227 into server and client lib as well.
4229 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added support for multiple nicknames on same channel. [n] is
4232 added locally to the nickname if there are more than one same
4233 nicknames on the channel.
4235 * Server now sends all nicknames that matched WHOIS request.
4236 Client also shows the list received from server.
4238 * Added TOPIC command to client side. User can now set and show
4239 current topic on channel.
4241 * Added MOTD command to client and server. Also, server sends the
4242 motd when client connects to the server.
4244 * Changed version strings to comply ISO 8601.
4246 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Fixed protocol error handling in client library. It should now
4249 cope even if the SKE fails for some reason.
4251 * Made new protocol specification drafts for submitting to IETF.
4253 * Implemented TOPIC command to server in silcd/command.c.
4255 * Added two new notify types into lib/silccore/silcnotify.h:
4256 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4257 notify nickname change and topic setting/change on a channel.
4259 * API change of command_reply operation in client library. The
4260 application gets now the status type received from server as well.
4262 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4266 * Cras fixed and optimized the packet handling even further and
4267 it should work now. Minor change to the prototype of function
4268 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4270 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added new function into lib/silcutil/silcschedule.[ch]:
4273 silc_schedule_with_fd to select() a specified fd. The function
4274 returns after timeout expires or data arrives or goes. The
4275 function is used by packet routines to wait that all data is
4276 received from network.
4278 * Fixed data reading from network in lib/silccore/silcpacket.c.
4279 The code now assures that all data is read from the fd and then
4280 continues packet processing. This was a bug fix since the code
4281 used to drop some data in some circumstances.
4283 * Added new function into lib/silcclient/client.[ch]:
4284 silc_client_start_key_exchange to start key exchange after
4285 connection has been established to server. The code internally
4286 now uses this funtion but its main purpose was to provide it
4287 for applications that perform their own connecting. After
4288 application has created a connection it merely calls this
4289 function to start the key exchange between client and server.
4290 The library takes care of everything else after that.
4292 Updated also lib/silcclient/README to explain the usage of
4295 * Do not send to application information that connection has
4296 been established. Application gets notified it by connect
4299 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Applied cras's patch to add silc_schedule_one function. The
4302 function runs scheduler once and returns.
4304 * Fixed the scheduler after cras messed it up. The timeout
4305 handling works now as it's supposed to work.
4307 * Added into lib/silccore/ silcnotify.h to include notify
4308 message types support. Changed silc_server_send_notify*
4309 functions, in server.[ch], to support those new notify types.
4310 Added the support for the notify types into client library,
4311 as well. Added new notify client operation into ops.h in
4314 * Changed silc_server_packet_send_to_channel to send normal
4315 packets instead of just channel message packets. The function
4316 is now used to send the notify packets to channels. It is not
4317 used to send channel message packets anymore, as server never
4320 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4321 va_arg()s as it seems to require it nowadays. I guess, if SILC
4322 is compiled with older va_arg() the new code should work anyway.
4324 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Splitted core library. Core library (lib/silccore) includes
4327 now only SILC protocol specific core (and common) components.
4328 Created new utility library (lib/silcutil) that includes more
4329 generic purpose stuff. The stuff for util library was taken
4330 from the old core library. This was minor and easy split.
4332 * Created SILC Client Library (lib/silcclient) that includes
4333 implementation of the SILC client without user interface. This
4334 was major move from silc/ directory. The code has been changed
4335 so that it is transparent towards the user interface. The
4336 silc/ directory includes now the same user interface as before
4337 and it uses the new client library. Read lib/silcclient/README.
4338 Basicly, the client library performs everything else related
4339 to SILC except user interface handling. Also, configuration
4340 files are considered to be part of user interface and library
4341 does not handle them.
4343 This change also changed a lot of structures, function naming etc.
4344 Most important change was that SilcClientWindow object was
4345 renamed to SilcClientConnection in the client library. Created
4346 also new file lib/silcclient/ops.h. Also added new files
4347 silc/local_command.[ch] and silc/client_ops.[ch].
4349 All these changes were made to make it easier for user interface
4350 designers to create what ever user interface for the SILC client
4353 It is also expected that the server will be moved to lib
4354 directory as well and SILC Server Library will be created;
4355 sometimes in the future.
4357 * Removed Local commands from lib/silccore/silccommand.h as
4358 they are application specific and new client library does not
4359 handle any of those anymore.
4361 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4362 old client implementation in silc/.
4364 * Added support for callback functions in SILC_LOG_* macros.
4365 Application can now set its own callbacks that will be called
4366 instead of using the default functions that will always print
4367 the debug messages to stderr (or stdout). Also, debugging can
4368 now be disabled by setting silc_debug to FALSE and re-enabled by
4369 setting it to TRUE. Note, that logging will still work even
4370 if debugging is disabled.
4372 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4373 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4374 silc_log_reset_debug_callbacks.
4376 * To enable debugging in silc client one must give now -d
4377 option on command line.
4379 * Changed silc_schedule_init to automatically allocate task queues
4380 if they are not allocated before calling it.
4382 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Added GMP 3.1 into math library.
4386 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4389 a channel in SILC network. The packet is used by servers and
4390 routers to notify other routers that user has left a channel.
4391 This little feature was missing until now. Added the feature
4392 to protocol specification as well.
4394 Added functions: silc_server_send_remove_channel_user and
4395 silc_server_remove_channel_user into server.[ch].
4397 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4398 lib/silccore/silcpacket.h. However, they are not implemented
4401 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Fixed joining to a channel and sending channel messages
4404 between server and router. The channel message sending should
4405 now work inside a cell.
4407 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Fixed the private message sending between server and router.
4410 The private message sending should now work inside a cell.
4412 * Added silc_server_replace_id into server.[ch] to replace
4413 existing ID in the SILC network.
4415 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4416 and silc_idlist_replace_server_id into idlist.[ch] in server.
4418 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Fixed the server to server connections. Server can again now
4421 connect to router. Router to router connections probably does
4424 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Added dynamic protocol registering support. Now protocols can
4427 registered and unregistered on the fly. Patch by cras.
4429 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added lib/contrib directory to hold routines that some platforms
4432 don't have but are needed by SILC.
4434 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4435 into lin/contrib to provide getopt() and getopt_long() for
4436 those who don't have it.
4438 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Added AWAY command to client. When away message is set and
4441 client receives a private message packet the client automatically
4442 replies to the sender with the away message.
4444 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4445 bug seemed to be the cause of recent problems when compiling
4448 * Added version detection support to SKE protocol specification
4449 and added the new changes to the SKE implementation as well.
4450 There were other minor changes in the SKE protocol as well.
4452 Many changes in lib/silcske/silcske.[ch] and in
4453 lib/silcske/payload.[ch].
4455 * Added ^U functionality, clear input line. Patch from cras.
4457 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Mainly small bugfixes on core library. Fixed some debugging
4460 logging and buffer overflow in silclog.c.
4462 * Updated config.sub and config.guess on the distribution tree.
4464 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added command lagging support in server. Client may execute
4467 commands now only once in two seconds.
4469 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Optimized packet reception. MAC computation and checking is now
4472 also more optimized. A lot previously duplicated code is now
4473 used as generic by both client and server.
4475 * Fixed key pair generation in clientutil.c
4477 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * Added into lib/silccore/silcbufutil.[ch] new function;
4480 silc_buffer_realloc.
4482 * Moved generic packet sending/encryption functions to
4483 lib/silccore/silcpacket.[ch] from client and server. Some
4484 rewriting of the functions.
4486 * Moved all generic packet reception/decryption functions to
4487 lib/silccore/silcpacket.[ch] from client and server. The
4488 packet processing is now much cleaner in both client and server.
4489 These were major changes in both client and server.
4491 * Created many common functions in server to do packet sending.
4492 Previously code were duplicated a lot, this has been removed
4495 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Rewrote major parts of the ID cache system. Don't know
4498 whether it is better now or not but at least the API is more
4501 * Major rewrite on ID cache stuff on client because of the ID
4502 cache API changes. Added idlist.c to client.
4504 * Also major rewrite on ID cache stuff on server as well.
4505 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4506 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4507 in hand, instead they are all put into the ID cache system now.
4508 All server_idlist_* routines uses ID cache now instead of
4509 traversing its own lists (those lists does not exist anymore).
4510 SilcIDList though still exists. Also, SilcXXXEntry's are
4513 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Finally made the SKE implementation compliant to the protocol
4516 specification. All mp integers are now binary encoded as
4517 opposed being HEX encoded.
4519 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4522 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4523 functions: silc_[encode/decode]_pem. Also added function
4524 silc_encode_pem_file to PEM encode with newlines ('\n') for
4527 * SILC public keys are now encoded either PEM or binary. Same
4528 option is for private keys as well. By default private keys
4529 are binary encoded and public keys PEM encoded. Silly HEX
4530 encoding were removed.
4532 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4533 function to create fingerprints.
4535 * Fixed a bug in SHA1; does not change the original data anymore.
4537 * Partly implemented INFO command on client and server side.
4538 Fixed CLEAR command. Changes to SERVER command; show current
4539 server(s) when giving command without arguments. Added
4540 VERSION command to client.
4542 * Added check to server that unregistered connections cannot
4543 execute commands (unless it is specificly allowed).
4545 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Fixed screen refresh.
4549 * Fixed channel joining bug from client. On some circumstances
4550 client tried to join to a channel it had already joined.
4552 * Added public key verification process into client's protocol.c.
4553 The client now verifies the public key from user and saves
4554 it into ~./silc/serverkeys/ directory.
4556 Added into: clientutil.[ch]: silc_client_verify_server_key.
4558 * Changed SKE protocol's silc_ske_initiator_finish function
4559 to accept callback function that verifies the received public
4560 key. Removed old silc_ske_verify_public_key function.
4562 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4565 silc_pkcs_private_key[_data]_set.
4567 * Made the password and public authentication more cleaner in
4568 server's protocol.c.
4570 * Removed historic and obsolete protocol `channel_auth' from
4571 both client and server.
4573 * Removed wrong way of sending command status messages from
4574 server to client in server's command.c. The old way violated
4575 protocol specification.
4577 Changes to silccore/silccommand.[ch]: removed
4578 silc_command_encode_status_payload -> not needed anymore,
4579 changed silc_command_encode_payload_va to accept extra
4580 argument on variable argument list. The argument type must
4581 now be provided to the function. Also, added new function:
4582 silc_command_encode_reply_payload_va which is same as
4583 normal command_encode_payload_va except command status type
4584 is provided as extra argument.
4586 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Added ~./silc directory handling. The directory includes the
4589 public and private keys for the client.
4591 Added silc_client_check_silc_dir, silc_client_create_identifier
4592 and silc_client_load_keys.
4594 * Implemented SILC protocol compliant public key. Added public
4595 and private key saving to and loading from files.
4597 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4598 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4599 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4600 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4601 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4603 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4604 silc_pkcs_load_[public/private]_key.
4606 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Added silc_server_get_route (route.[ch]) to get connection
4609 data for the fastest route for given ID.
4611 * Implemented INVITE command on client and server. The command
4612 were re-defined in the SILC Protocol Specification and the
4613 implementation now complies with the specification.
4615 * Implemented PING command on client and server.
4617 * Implemented NAMES command on client and server. The server side
4618 supports currently only normal server not router server yet.
4619 Some changes to NAMES definition in SILC protocol specification.
4621 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Implemented LEAVE command on client and server.
4625 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4626 again. This change was made to the protocol as well. Server
4627 should not violate the protocol specification anymore.
4629 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4632 was tested. SOCKS4 was not but should work anyway.
