3 * Found a bug in the SKE implementation. The HASH value,
4 specified by the protocol, was not computed correctly. The
5 public key of the responder was not added to the computation
6 even though it is mandatory. Affected file lib/silcske/silcske.c.
7 This unfortunately causes incompatibilities with older
10 * Added WIN32 specific network init and uninit functions:
11 silc_net_win32_init and silc_net_win32_uninit to init and uninit
12 the Winsock2. Affected file lib/silcutil/silcnet.h and
13 lib/silcutil/win32/silcwin32net.c.
15 * Set the socket always to nonblocking mode on WIN32 after
16 reading data or writing data. Affected file is
17 lib/silcutil/win32/silcwin32sockconn.c.
19 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Fixed various compilation problems under WIN32. Affected
22 files lib/silcutil/win32/silcwin32thread.c and
23 lib/silcutil/win32/silcwin32schedule.c.
25 * Removed all _internal.h #includes from public header
26 files. Internal headers must never be included from
29 Removed also the lib/silcske/payload_internal.h file.
31 * All include files that may be needed (public and some others
32 included by the public headers) by application developers are
33 now copied to the ./includes directory. It does not copy any
34 internal headers. Affected file Makefile.defines.pre and all
35 Makefile.am's under lib/ and subdirs.
37 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Do not change the ~/.silc directory's permissions automatically.
40 Affected file irssi/src/silc/core/clientutil.c.
42 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
44 * Do not cancel the protocol in silc_server_close_connection
45 it might cause recursion. Now cancelled in the function
46 silc_server_free_sock_user_data. Affected file silcd/server.c.
48 * Fixed the silc_server_remove_clients_by_server to regenerate
49 the channel keys correctly finally. Added also new function
50 silc_server_remove_clients_channels to actually do it.
51 Affected file silcd/server.c.
53 * Fixed the silc_server_new_channel to not crash by giving
54 wrong router to the new channel. Affected file is
55 silcd/packet_receive.c.
57 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
59 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
60 which is given as argument to the silc_client_alloc now.
61 It can be used to configure the client and set various parameters
62 that affect the function of the client.
64 * The USERS command in server did not check whether the channel
65 is private or secret. Affected file silcd/command.c.
67 * Added new argument to the USERS command in protocol specification.
68 The USERS command now can take the channel name as argument
69 as well. Added support for this in client and server and
70 updated the protocol specs.
72 * Completed the GETKEY command in client. It can be now used
73 to fetch also servers public key not only some clients.
74 Affected files lib/silcclient/command[_reply].c.
76 * Added silc_client_get_server to return server entry by the
77 server name. Affected files lib/silcclient/silcapi.h and
80 * Redefined the IDENTIFY command in protocol specification to be
81 more generic. It now can be used to query information about
82 any entity in the SILC Network, including clients, servers and
83 channels. The query may be based either the entity's name
84 or the ID. Added support for this in both client and server.
86 Affected files silcd/command.c and lib/silcclient/command.c
89 * Optimized the WHOIS and WHOWAS commands in the server. Removed
90 the _from_client and _from_server functions. Affected file
93 * Added silc_client_get_channel_by_id_resolve to the file
94 lib/silcclient/silcapi.h to resolve channel information by
95 its ID. Added also silc_client_get_channel_by_id that
96 does not resolve it from the server.
98 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
100 * Added SilcServerEntry context into the client library
101 to represent one server. The INFO command now allocates
102 these to save the resolved server info. For now on the
103 client library will also keep information about servers,
104 connected and resolved with INFO.
106 The INFO command now allocates the SilcServerEntry context
107 and saves the server info there. The COMMAND_REPLY in
108 the INFO now returns the parameters to application in
109 same order as defined in the protocol specification.
111 The entries are cached in the client->server_cache.
113 * The INFO command is now issued after received the Client ID
114 from the server. Affected file lib/silcclient/client.c.
116 * The CMODE_CHANGE notify may now return also an SilcServerEntry
117 to the application as the mode changer might be server.
118 It is guaranteed that NULL is not returned anymore to the
119 application. Affected file lib/silcclient/client_notify.c.
121 The ID Type is now also passed to the application so that
122 it can check whether the returned entry is SilcClientEntry
125 Added new function silc_client_get_server_by_id to return
126 the server entry by ID. Affected files are the
127 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
129 * Do not create the channel in the Irssi SILC Client when issuing
130 the JOIN command but when received the sucessful JOIN command
131 reply. Otherwise the channel might get created even though we
132 could not join it. The Affected file is
133 irssi/src/silc/core/[silc-channels.c/client_ops.c].
135 * Fixed a channel joining bug in router. The router must also
136 check the channel modes, invite and ban lists etc. when serving
137 the JOIN command sent by normal server. Affected file is
138 silcd/command.c. The router now resolves the client's
139 information from the server who sent the JOIN command if it
140 does not know it, and processes the JOIN command only after
143 * Changed the SilcCommandCb to take new argument; void *context2.
144 Affected file lib/silccore/silccommand.h
146 The second argument in the command callbacks in the server now
147 includes the SilcServerCommandReplyContext if the command was
148 called as pending command callback from the command reply.
149 Otherwise it is NULL. When called as pending the status of the
150 command reply will be checked and if it was erronous the
151 error will be sent to the original sender of the command.
152 This way the client always receives the error messages even
153 though the server was actually the one who received the error
154 when it resent the command to router, for example. Affected
155 files silcd/command[_reply].[ch].
157 * Fixed sending WHOWAS command's error message to client if
158 the requested client could not be found. It was missing.
161 * Changed the CMODE and CUMODE commands reply arguments in the
162 protocol specification. The Channel ID is now sent in both
163 of the commands to identify the channel. Implemented this
164 new feature to the client and server. Affected files
165 lib/silcclient/command_reply.c and silcd/command.c.
167 * Made better checks for invite and ban lists in the JOIN
168 command in server. Affected file silcd/command.c.
170 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
172 * The server now performs the incoming host IP/DNS lookup
173 using the silc_socket_host_lookup and thus does not block
174 the server anymore. Affected file silcd/server.c.
176 * Completed the multi-thread support for SILC Scheduler in
177 the lib/silcutil/silcschedule.c.
179 * Fixed the configure.in.pre to detect the pthread correctly
182 * Fixed a deadlock in silc_task_queue_wakeup in the file
183 lib/silcutil/silctask.c.
185 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
187 * Added new function silc_schedule_wakeup that is used in
188 multi-threaded environment to wakeup the main thread's
189 schduler. It needs to be used when a thread adds a new task
190 or removes a task from task queues. After waking up, the
191 scheduler will detect the task queue changes. If threads
192 support is not compiled in this function has no effect.
193 Implemented the wakeup mechanism to both Unix and WIN32
194 systems. Affected files are lib/silcutil/silcschedule.[ch],
195 lib/silcutil/unix/silcunixschedule.c and the
196 lib/silcutil/win32/silcwin32schedule.c.
198 * Added new function silc_task_queue_wakeup to wakeup the
199 scheduler by the specified task queue. Affected file
200 lib/silcutil/silctask.[ch].
202 * The silc_socket_host_lookup_start now wakes up the scheduler
203 after adding the timeout task. Affected file is
204 lib/silcutil/silcsockconn.c.
206 * The silc_socket_host_lookup is synchronous now if the threads
207 support is not compiled in. However, the callback is still
208 called asyncronously through the scheduler, anyway. Affected
209 file lib/silcutil/silcsockconn.c.
211 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
213 * Added new function silc_socket_host_lookup to perform
214 asynchronous IP and FQDN lookups for the socket connection.
215 Affected files lib/silcutil/silcsockconn.[ch].
217 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
219 * Added SILC_MUTEX_DEFINE to define the mutex on environments
220 that may or may not compile the mutex support in.
222 Changed the silc_mutex_alloc interface. It allocates the
223 mutex now to the sent pointer and returns TRUE or FALSE.
225 Affected file lib/silcutil/silcmutex.h.
227 * Wrote the SILC Task Queue interface to support multi-threads.
228 Affected file lib/silcutil/silctask.[ch].
230 * Wrote the SILC Scheduler to support multi-threads. Affected
231 file lib/silcutil/silcschedule.c.
233 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
235 * Implemented the SILC Mutex API and SILC Thread API for WIN32
236 in lib/silcutil/win32/.
238 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
240 * Defined SILC Mutex API and SILC Thread API and implemented
241 them for Unix. Affected files are
242 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
243 lib/silcutil/unix/silcunixmutex.c and
244 lib/silcutil/unix/silcunixthread.c.
246 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Fixed the silc_server_remove_clients_by_server's channel
249 key re-generation. The hash table handling was incorrect
250 and would not work with many channels. Affected file is
253 * Fixed some memory leaks around the server code.
255 * Rewrote the silc_server_get_users_on_channel to support IPv6
256 based Client ID's. Affected file silcd/server.c.
258 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
259 specification. However, a separate document must be written
260 to define the detailed signing procedure and the payload
261 associated with the flag. Defined the flag to the
262 lib/silccore/silcchannel.h as well.
264 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
266 * Changed the dynamic tables to static size tables in the
267 lib/silccrypt/silchmac.c.
269 * Removed GCC dependencies from the code. A patch by cras.
271 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
273 * Do not show the error "Error receiving packet bla bla"
274 in server if it really was not an error (-2 means that reading
275 is pending). Affected file silcd/server.c.
277 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
279 * Fixed a possible crash in silc_server_remove_clients_by_server
280 in silcd/server.c. Fixed there also some memory leaks.
282 * Fixed the silc_idlist_replace_client_id. It could replace
283 wrong key in the hash table. Affected file silcd/idlist.c.
285 * Do not check whether there are global users on the channel
286 if the channel->global_users is FALSE. Affected functions
287 silc_server_remove_from_one_channel and
288 silc_server_remove_from_channels in silcd/server.c. Also,
289 do not check if the removed client is local as we can be
290 sure that global client was not removed from the channel
291 and checking for global users is not needed.
293 * The silc_server_remove_clients_by_server now re-generates
294 the channel keys correctly for those channels that had
295 clients removed from them. Affected file silcd/server.c.
297 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Found the reason of random crashes in the server. We weren't
300 ignoring the SIGPIPE signal (which can be sent in write())
301 and it crashed the server. Affected file silcd/silcd.c.
303 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Assure that sock->user_data is not NULL in the function
306 silc_server_packet_send in silcd/packet_send.c.
308 * Disconnect the remote connection if it could not be added
309 to any ID lists in the server. The affected file is
312 * Check in silc_server_packet_send[_real/dest] that the
313 socket is not disconnecting and ignore the data if it is.
314 Affected file silcd/packet_send.c.
316 * Define inline to __inline on native WIN32 compilation.
317 Affected file includes/silcwin32.h.
319 * Added some explicit type casts for inline code since MSVC
320 require them. Affected files lib/silcutil/silcbuffer.h,
321 lib/trq/silcdlist.h and lib/trq/silclist.h.
323 * Print warning in log files from now on if the packet
324 decryption fails. Affected file silcd/server.c.
326 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
328 * Changed the `say' client operation's interface to accept
329 new `type' argument to indicate the type of the message sent
330 by the library. The application may filter the library's
331 messages according the type. The affected file is the
332 lib/silcclient/silcapi.h.
334 * Added two new functions to lib/silcclient/silcapi.h:
335 silc_client_del_client and silc_client_del_client_by_id.
336 Affected file lib/silcclient/idlist.c.
338 * Moved the clientincludes.h from includes/ to silc/ and
339 serverincludes.h from includes/ to silcd/.
341 * The modes for the CMODE and CUMODE are now passed as
342 uint32 for application with COMMAND_REPLY. The affected
343 file is lib/silcclient/command_reply.c.
345 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
347 * /WHOIS without arguments shows client's own information.
348 Affected file lib/silcclient/command.c.
350 * Changed PING to not accept any arguments. The specs
351 says that client can ping only the connected server so
352 requiring an argument is not needed. Affected file is
353 lib/silcclient/command.c.
355 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
357 * Fixed a fatal bug in private message sending and reception
358 encryption and decryption when using private message keys.
359 The implementation was incorrect and did not follow the
360 specification. It causd that some of the message were
361 lost since it did not use the sending and receiving keys
362 as the protocol suggests. This has been fixed and will cause
363 incompatibilities with older clients when sending private
364 message encrypted with private message keys. Affected files
365 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
366 and various other in Irssi SILC Client.
368 Added `responder' boolean argument to the functions
369 silc_client_add_private_message_key[_ske] to indicate when
370 the key is added as responder or initiator of the key
373 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
375 * Removed the silc_ske_check_version function and created
376 a SilcSKECheckVersion callback. Added also a function
377 silc_ske_set_callbacks that is now used to set all SKE
378 callbacks. The callback functions are not given to
379 the SKE functions anymore, but this function is used to
382 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
384 * Added `silc_version' argument to the silc_client_alloc
385 to define the version of the application for the library.
386 The library will use the version string to compare it
387 against the remote host's (usually a server) version
388 string. Affected file lib/silcclient/silcapi.h
390 * Added the KE protocol context to Key Agreement context
391 in client library so that we can abort the SKE if it
392 is in process when we get timeout. Affected file is
393 lib/silcclient/client_keyagr.c.
395 * Do not resolve the client ID forever if it returns in the
396 first time that such client does not exist. This was done
397 for example with private message. Affected file is
398 lib/silcclient/client_prvmsg.c.
400 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Do not add regex.h for WIN32. The affected file
403 includes/silcincludes.h.
405 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
406 not work yet 100%. It generates the DLL's automatically
407 when compiling with --with-win32 under cygwin.
409 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
411 * lib/contrib/regex.c is not compiled on WIN32.
413 * Added silc_net_get_socket_opt function to the
414 lib/silcutil/silcnet.h.
416 * Added includes/silcwin32.h for WIN32 specific includes
419 * Do not use ptime structure or any of the posix process
420 functions on WIN32 in lib/silccrypt/silrng.c.
422 * Added silc_gettimeofday to provide generic function
423 for struct timeval on all platforms. Added the function
424 to lib/silcutil/silcutil.h.
426 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Moved the lib/silccore/silcsockconn.[ch] to the utility
429 library as they clearly belong there. As a plus side we
430 can make the actual socket connection routines platform
433 Added also new generic function silc_socket_read and
434 silc_socket_write (that used to be silc_packet_[read/write].
435 The implementation of these are platform specific.
437 * Added WIN32 specific routines of silc_socket_[read/write]
438 to lib/silcutil/win32/silcwin32sockconn.c.
440 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
442 * Added preliminary support for native WIN32 compilation under
443 cygwin (using the -mno-cygwin option for GCC) to the
444 ./configure.in.pre. The --with-win32 now prepares the
445 compilation for native WIN32.
447 * Rewrote the SILC Scheduler interface in the file
448 lib/silcutil/silcschedule.h. The scheduler is now context
449 based and does not have anymore any global static scheduler.
450 Moved the Unix scheduler to the lib/silcutil/unix/ directory
451 and created lib/silcutil/win32 directory for WIN32 based
454 * Added Unix specific network routines to the
455 lib/silcutil/unix/silcunixnet.c and the old
456 lib/silcutil/silcnet.c includes now only generic routines.
458 Added WIN32 specific network routines to the
459 lib/silcutil/win32/silcwin32net.c.
461 * Added Unix specific utility functions from the
462 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
464 * Added WIN32 SILC Scheduler to the file
465 lib/silcutil/win32/silcwin32schedule.c. The code is of course
468 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
470 * Do not handle JOIN notify in the server if the target client
471 is not registered (idata->registered == FALSE). The affected
472 file is silcd/packet_receive.c.
474 * Update the nickrec->founder in event_cumode in the Irssi SILC
475 client. Affected file irssi/src/silc/core/silc-channels.c.
477 * Fixed the CUMODE_CHANGE notify handling in the server when
478 server and router are announcing their clients on channels.
479 Now the mode changes are saved and notified correctly. The
480 affected file is /silcd/packet_receive.c.
482 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
483 They really did not replace the cache entry in the ID Cache.
484 Now they do that. Affected file silcd/idlist.c.
486 * Fixed the KICK notify handling in the Irssi SILC client to
487 update the channel records so that the kicked client does not
488 appear to be on the channel. The affected file is
489 irssi/src/silc/core/silc-channels.c.
491 * Always update the conn->current_channel when executing command
492 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
494 * Fixed the KILL notify handling in Irssi SILC client to remove
495 the killed client on all channels.
497 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
499 * Fixed the silc_parse_command_line to remove extra spaces
500 from the start and end of the arguments. Affected file is
501 lib/silcutil/silcutil.c.
503 * Cancel and free any active protocol in the function
504 silc_server_close_connection. Affected file silcd/server.c.
506 * Cancel and free any active protocol in the function
507 silc_client_close_connction. Affected file is
508 lib/silcclient/client.c.
510 * Do not execute the KILL command for clients that are in
511 history (ie. they are not in the network). Affected file is
514 * Fixed KILL notify handling, client does not crash anymore.
515 Affected file irssi/src/silc/core/silc-channels.c.
517 * Reduced the default packet buffer size from 2048 to 1024 in
518 lib/silccore/silcpacket.c.
520 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
521 counter to the SKE context that is incresed when the SKE library
522 performs async operation outside the library. If the outside
523 process frees the SKE context and FREED status will be set
524 and the library will detect after the sync operation that the
525 libary is freed. The affected files are
526 lib/silcske/silcske[_status].[ch].
528 * Resolve the client entry information in the function
529 silc_client_channel_message to assure that NULL pointer is not
530 passed as client entry to the application. */
532 * Fixed the task timeout calculation to assure that there is
533 never negative timeouts. The affected file is
534 lib/silcutil/silcschedule.c.
536 * Fixed the channel user mode notification sending in server.
537 It was sent point-to-point to the router (or to server by router)
538 but it needs to be destined to a channel. The routines now
539 supports sending the channel user mode notifys to the channels
540 when announcing clients and channels. Affected files are
541 silcd/server.c and silcd/packet_receive.c.
543 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
544 It did not actually replace the old channel entry in the cache.
545 Affected file lib/silcclient/client_notify.c.
547 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Fixed a possible crash in silc_packet_send_prepare. It now
550 assures always that there is enough space in the buffer and
551 at the tail area of the buffer (for MAC).
553 Fixed the inbound buffer reallocation in silc_packet_read.
554 It was old code and did not handle the reallocation correctly.
557 The affected file is lib/silccore/silcpacket.c.
559 * Fixed buffer overflow in silc_parse_nickname in the file
560 lib/silcutil/silcutil.c.
562 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * make install generates new server keys only if there is not
567 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
569 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
570 Added check that if the NOREPLY is set then we will not send
571 the away message. This avoids infinite loop of away messages
572 if both clients are away. The affected file is
573 lib/silcclient/client_prvmsg.c.
575 * Fixed client crash if /NICK was given without arguments.
576 Affected file lib/silcclient/command.c.
578 * Server does not send the invite list in INVITE command back
579 to the client if the list was not altered. Added this notion
580 to the protocol spec as well. Affected file silcd/command.c.
582 Fixed possible crash in INVITE command by checking the
583 value of silc_server_get_client_route command.
585 * Fixed the INVITE notify type handling. The arguments are now
586 taken in correct order and client does not crash. The affected
587 file is irssi/src/silc/core/silc-channels.c.
589 Removed the "Inviting xxx to channel" message from the
590 client library away and let the application handle it.
591 Affected file lib/silcclient/command.c. Added that message
592 to Irssi SILC client's message formats.
594 * Fixed CMODE command crash in client. It now checks the
595 amount of arguments correctly and does not crash. The affected
596 file is lib/silcclient/command.c.
598 * Do not create new channel automatically in silc_channels_join
599 but check whether the channel by that name already exists.
600 Affected file irssi/silc/core/silc-channels.c.
602 * Do not send the SERVER_SIGNOFF to router if the disconnected
603 entity was the router. Affected file silcd/server.c.
605 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
606 SILC client as it was missing from there.
608 Added the handling of the KICK notify to the Irssi SILC client
609 as it was missing. Added "you have been kicked" message to
610 Irssi SILC client's message modules formats.
612 Added the handing of the KILL notify to the Irssi SILC client
613 as it was missing. Added the kill message module formats
616 The affected file is irssi/src/silc/core/silc-channels.c.
618 * The router did not save the channel mode the server announced.
619 Affected file silcd/packet_receive.c.
621 * Fixed a possible crash in INFO command in server. If the
622 server did not provide the server info it crashed. Affected
623 file silcd/command.c.
625 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * Fixed the GETKEY command in the server to check also the
628 global list. Otherwise the GETKEY would not work correctly
629 in normal SILC server. Affected file silcd/command.c.
631 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Fixed GETKEY crash, it crashed if the command did not succseed.
635 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
637 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
638 is now real and not just an macro interface to GMP.
640 Removed the entire GMP from the source tree and imported new
641 NSS MPI library instead. Reason for removing GMP is that it is
642 extremely large and compiles extremely slow. The NSS MPI
643 is only a few files and compiles in less than 10 seconds.
644 The speed is also about the same as GMP. The MPI is imported
647 If the system has GMP installed we will still use the GMP.
648 If it is not then the NSS MPI will be compiled.
650 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Merged a long nickname (127 characters long) crash bugfix from
653 Irssi CVS tree. Affected file irssi/src/core/misc.c.
655 * Merged a freed memory reference bugfix from Irssi CVS tree.
656 Affected file irssi/src/core/commands.c.
658 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Added the server's public key sving and verification to the
661 server when performing the SKE. This was missing and the
662 remote server's (or router's) public key was accepted without
663 checking whether we have it previously or trust it at all.
664 Affected file silcd/protocol.c.
666 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Check in the silc_server_timeout_remote if protocol is active
669 and make sure that the protocol's final callback is called so
670 that all memory if freed. Affected file silcd/server.c.
672 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * silc_server_whois_send_reply crashed the server if the nickname
675 was 127 characters long. Affected file silcd/command.c.
677 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Added sanity check to the silc_server_new_client. If the hostname
680 is provided inside username then check that the provided hostname
681 really is the same as the resolved one. If the hostname was not
682 resolved then check it from the public key. Affected file is
683 silcd/packet_receive.c.
685 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
686 if the server disconnected us and the connection is not valid
687 anymore. Affected file irssi/src/silc/core/silc-channels.c.
689 * Moved the silc_client_[chmode|chumode|chumode_char] away from
690 the library to the lib/silcutil/silcutil.[ch].
692 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Close log file after open. Affected file
695 lib/silcutil/silclog.c.
697 * Check whether sock == NULL in silc_client_send_packet and return
698 if it is. Affected file lib/silcclient/silcclient.c.
700 * Check rec->entry == NULL in the Irssi SILC Client before
701 sending the channel message. Affecte file is
702 irssi/src/silc/core/silc-servers.c.
704 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Merged a splitted window bugfix from Irssi CVS tree. The
707 affected file is irssi/src/fe-text/textbuffer-view.c.
709 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
710 It did not print nickname.
712 * Improved the distributions system a bit.
714 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
717 irssi/src/fe-text/gui-window.c.
719 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
720 to in-active server. The affected file is
721 irssi/src/silc/core/client_ops.c.
723 * Resolve the client in USERS command reply if the entry does
724 not have username resolved. The affected file is
725 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
726 command to WHOIS command to really resolve stuff. The USERS
727 is not used any more in any critical section so WHOIS can
728 be used even though it might be slower than IDENTIFY.
730 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
733 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Changed the protocol API a bit more consistent in the
736 lib/silccore/silcprotocol.[ch].
738 * Changed the following headers to ROBODoc format:
740 lib/silccore/silcpayload.h
741 lib/silccore/silcprotocol.h
742 lib/silccore/silcsockconn.h
744 All core library headers are now formatted.
746 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Fixed a bug in Irssi SILC client; do not show that you are
749 server/router operator if you really are not. Affected file is
750 irssi/src/silc/core/client_ops.c.
752 * Renamed silc_command_free_payload to silc_command_payload_free.
753 Affected file lib/silccore/silccommand.h
755 * Added silcmath.h to include the prototoypes of various routines
756 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
759 * Changed the following headers to ROBODoc format:
761 lib/silccore/silcchannel.h
762 lib/silccore/silccommand.h
763 lib/silccore/silcid.h
764 lib/silccore/silcidcache.h
765 lib/silccore/silcmode.h
766 lib/silccore/silcnotify.h
767 lib/silccore/silcpacket.h
768 lib/silcmath/silcmath.h
770 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Added checking to the server code not to start the server if
773 ciphers and stuff are not configured properly. Affected files
774 silcd/serverconfig.[h] and silcd/server.c.
776 * Changed the layout of the header files of the public interfaces
777 in the SILC libraries. The new layout supports ROBODoc
778 documentation tool (and some others) so that it is easy to create
779 a library reference manual. All the other headers and source
780 code must still follow the CodingStyle document. Also source
781 code must not include these ROBODoc stuffs, only the headers.
782 Furthermore, all public interface headers must now be named
783 by using `silc' prefix, example: silcapi.h, silccipher.h.
784 Some files were renamed due to this. All the other headers
785 must not be used as public interfaces. I will update the
786 CodingStyle document later. Changed following headers, so far:
788 lib/silcclient/silcapi.h
789 lib/silccore/silcauth.h
790 lib/silccore/silcprivate.h
791 lib/silccrypt/silcdh.h
793 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Removed silc_client_packet_send_flush from the client library
798 as it is not needed. Affected file lib/silcclient/client.[ch].
800 * Added printing of message of unresolved authentication method
801 to the Irssi SILC client. Added it to the module formats.
802 Removed the same message from the client library.
804 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Added new distribution feature, DISTLABEL. Every distribution
807 can define own preprocessor label that can be used in the
808 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
809 file distributions, acconfig.h.pre and prepare.
811 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
813 * Added Makefile.defines_int to include the actual definitions
814 for Makefile.defines.in. Tested the new distribution system,
815 created distributions and tested installation.
817 * Added AWAY message printing to the Irssi SILC client. Added
818 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
820 * Added SCONNECT command to call the SILC's CONNECT command.
821 Cannot use CONNECT directly since Irssi uses that internally.
822 Affected file irssi/src/silc/core/silc-servers.c.
824 Added ACTION local command. It is same as ME command but takes
825 the channel as mandatory argument.
827 Rewrote some of the Irssi's help files to suite for SILC
830 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Added Makefile.defines[.in] that should for now on be included
833 in all Makefile.am file in the source tree. That file includes
834 all common compilation definitions for SILC source tree.
836 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
838 * Minor changes to the ./prepare script to change the package
839 name according the distribution name to the configure.in.
841 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Created new distribution system. Added file `distributions'
844 that defines all the distributions that can be created out of
845 the SILC source tree. The ./prepare script now reads that
846 file to determine how to prepare the distributions. The
847 first argument to the ./prepare is the name of the distribution
848 and second is the version of the distribution. If given
849 without arguments it creates the default (toolkit) distribution
850 with the default version (defined in ./prepare).
852 All Makefile.am files that are subject to the distributions
853 are now named as Makefile.am.pre. These are ./Makefile.am
854 and lib/Makefile.am. Others may be changed later.
856 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Added invite list, ban list, some key management and connection
859 error message printing to module formats in the Irssi SILC client.
861 * Added new silc_client_set_away_message to set the away message
862 that is back to the person who sent private message. The
863 affected file lib/silcclient/silcapi.h and the
864 lib/silcclient/client_prvmsg.c.
866 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
868 * Fixed the private message sending in the Irssi SILC client,
869 added local command KEY to the Irssi SILC client.
871 Added key management and key agreement message formats to the
872 irssi/src/fe-common/silc/module-formats.[ch].
874 Added USERS (alias WHO) printing, server/router operator
875 indication and LIST command printing to the module formats.
877 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Fixed channel joining notify handling, cumode notify handling
880 from Irssi SILC client.
882 * Added SILC specific module-formats to the Irssi SILC client so
883 that SILC specific message hilighting, colors etc is possible.
884 Affected file irssi/src/fe-common/silc/module-formats.[ch].
886 Added channel mode, channel user mode, actions, notices,
887 whois and whowas printing to the the module-formats.c.
889 * Fixed a bug in channel deletion in the server. The channel
890 is not left to the cache even if the channel founder auth mode
891 is set when there are no users anymore on the channel. Affected
894 * The silc_net_localhost now resolves the entire hostname including
895 the domain name. Affected file lib/silcutil/silcnet.c.
897 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
899 * Changed the ask_passphrase client operation to be ascynchronous.
900 It has now a completion callback and a context that the
901 application must call after it has got the passphrase from
902 the user. Affected files lib/silcclient/silcapi.h,
903 lib/silcclient/protocol.c, lib/silcclient/command.c and
906 Added SilcAskPassphrase callback that the application calls
907 to deliver the passphrase to the library.
909 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
910 The public key verification and especially a certificate
911 verification is asynchronous procedure.
913 Added new SILC_SKE_STATUS_PENDING status to indicate the
914 request is pending and a callback will be called to finalize
917 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
918 indicate that remote end did not send its public key (or
919 certificate), even though we require it. Added check for this
920 condition in the SKE. This was a security bug, now fixed.
922 Defined new SilcSKEVerifyCbCompletion callback that is called
923 when the verification process is completed.
925 The affected files lib/silcske/silcske_status.h and
926 lib/silcske/silcske.[ch].
928 * Changed the verify_public_key client operation to be async
929 as well. Defined SilcVerifyPublicKey callback that is used to
930 indicate the success of the public key verification process.
932 Changed the server and client to use the new async client
935 * Changed the Irssi SILC client's internal scheduler to be called
936 twice as many times as it used to be. As a result the client
937 should be a bit faster now. Affected file is
938 irssi/src/silc/core/silc-core.c.
940 * Added support to Irssi SILC client of asynchronous public key
941 verification and passphrase inquiry. Affected file is
942 irssi/src/silc/core/silc-core.c.
944 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Do not say "You have left channel %s" in client library.
947 Moved it to the application. Affected files are
948 lib/silcclient/command.c and silc/client_ops.c.
950 * Fixed silc_client_get_clients. Command context was not
951 duplicated and was freed memory in the callback. Affected
952 file lib/silcclient/idlist.c.
954 * Do not say "you are now talking..." on JOIN command in the
955 client library. The appliation must handle it.
957 * Do not say ".. changed topic to" in command reply in the
958 client libary. The application must handle it.
960 * Fixed TOPIC command sending in the client library.
962 * Fixed a memory leak in silc_client_command_free in the file
963 lib/silcclient/command.c.
965 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Imported a modified version of Irssi client to the source tree.
968 The Irssi will be used to create a new client called
969 Irssi SILC. Imported to irssi/.
971 Added silc_core_init_finish function to the Irssi. Affected
972 file irssi/configure.in.
974 A lot changes in the Makefile.ams around the irssi tree.
976 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Do not rehash if the new size is same as the old size of the
979 hash table, in the silc_hash_table_rehash*. The affected file
980 lib/silcutil/silchashtable.c.
982 * Replaced hash_table_del_by_context calls from the server
983 (when channel->user_list and client->channels) to the
984 hash_table_del as it is sufficient and faster.
986 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Added silc_hash_table_list, silc_hash_table_get and the
989 SilcHashTableList structure to provide an alternative way to
990 traverse the hash table. The affected files are
991 lib/silcutil/silchashtable.[ch].
993 * Changed the server's idlist routines to use the hash table
994 routines to optimize the code.
996 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Replaced the client entry's `channel' list and channel entry's
999 `user_list' list to hash tables for optimized lookup. Changed
1000 the code to use the hash table interface around the code.
1001 Affected file lib/silcd/idlist.[ch].
1003 * Added `auto_rehash' boolean argument to the function
1004 silc_hash_table_alloc to indicate whether the hash table should
1005 auto-rehash when it thinks is appropriate time. It will
1006 increase the hash table size if the there is twice as much
1007 entries in the table than the size of the table, and will
1008 decrease the size if there are twice as less entries than
1009 the size of the table.
1011 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1013 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1015 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1017 * silc_idcache_purge_by_context deletes the entry now by context
1018 as it is supposed to do. Affected file lib/silccore/idcache.c.
1020 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1021 client is not anymore valid (WHOWAS givens the info) and not
1022 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1024 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Removed the `data' and `data_len' arguments from the ID Cache
1027 interfaces and added `name' argument. ID Cache does not handle
1028 anymore the binary data only a names associated with given ID.
1030 * When hashing a Client ID with silc_hash_id the entire ID is
1031 not hashed anymore, instead only the hash of the Client ID is
1032 hashed. This way we can access the Client ID from the cache
1033 with Client ID but with the hash of the ID (which is a hash of
1034 the nickname) as well without any difference in performance.
1036 Added also silc_idcache_find_by_id_one_ext to do one on one
1037 searching when we have the actual ID. Added also function
1038 silc_hash_client_id_compare. The affected files are
1039 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1041 * When hashing the name associated with a ID it is always done
1042 in lowercase. This way we can access the cache without worrying
1043 about case-sensitivity, even though, for example nicknames are
1046 * Fixed a bug in server with channel message sending. It put
1047 wrong ID type as destination ID. The affected file
1048 silcd/packet_send.c.
1050 * silc_idcache_del_by_context now deletes from all hash tables
1051 by context. Affected file lib/silccore/idcache.c.
1053 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Changed the client library to use the new ID Cache interface.
1056 Changes around the source tree.
1058 * Added silc_hash_table_rehash_ext to rehash with specific
1059 hash function. Affected file lib/silcutil/silchashtable.[ch].
1061 * Added silc_hash_string_compare to compare two strings in the
1062 hash table. Affected file lib/silcutil/silcutil.[ch].
1064 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added new function silc_idcache_del_by_context into the
1067 lib/silccore/idcache.[ch].
1069 * Changed the server's ID list routines to use the new ID Cache
1070 interface. Changes around the source tree.
1072 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Added silc_hash_table_del[_by_context]_ext functions in to the
1075 lib/silcutil/silchashtable.[ch].
1077 Removed silc_hash_table_find_all* routines and added new
1078 silc_hash_table_find_foreach to replace them.
1080 Added silc_hash_table_replace_ext function as extended
1081 replacing function. Separated the simple hash table interface
1082 from the extended hash table interface in the file
1083 lib/silcutil/silchashtable.h.
1085 * Fixed minor bugs and changed it to use some of the new
1086 hash table functions in lib/silccore/idcache.c
1088 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Added new function silc_hash_table_find_all to return all keys
1091 in the hash table by the specified key. As the hash table is
1092 collision resistant it also makes it possible to have several
1093 duplicate keys in the hash table. This function may be used to
1094 find all of the keys from the hash.
1096 Added user_context arguments to the SilcHashFunction,
1097 SilcHashCompare and SilcHashDestructor to deliver user specified
1100 Added new fuctions silc_hash_table_find[_all]_ext to do
1101 extended lookup with specified hash and compare functions and
1102 specified user contexts.
1104 Added new function silc_hash_table_add_ext to add the key
1105 with specified hash function and user context.
1107 Added new function silc_hash_table_foreach to traverse all
1108 entrys in the hash table. Added SilcHashForeach callback
1111 Added new function silc_hash_table_del_by_context to delete
1112 the entry only if the context associated with the key matches.
1114 Affected files are lib/silcutil/silchashtable.[ch].
1116 * Removed silc_hash_[server/client/channel]_id and added just
1117 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1118 silc_hash_id_compare to compare two ID's using as the hash table
1119 comparison function. Added also silc_hash_data to hash
1120 binary data and silc_hash_data_compare to compare it.
1122 * Removed silc_idlist_find_client_by_hash as it is not needed
1123 anymore. Affected file silcd/idlist.[ch].
1125 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1126 to use internally the SilcHashTable. The new ID Cache is a lot
1127 faster than the old one. Some of the ID Cache interface was also
1128 rewritten and obsolete and stupid functions were removed.
1130 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Added entry_count field to the SilcHashTable to keep the number
1133 of the entries in the table. Implemented the function
1134 silc_hash_table_rehash. Added new function
1135 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1137 Fixed a minor bug in silc_hash_table_free.
1139 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1140 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1141 into the lib/silcutil/silcutil.[ch].
1143 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1145 * Implemented a collision resistant hash table into the
1146 lib/silcutil/silchashtable[ch]. See the header and the source
1147 for the SilcHashTable API.
1149 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Merged dotconf version 1.0.2 into lib/dotconf.
1153 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1155 * Do not compile anything in lib/silcsim/* if the SIM support
1156 is not enabled. The tree should now compile without problems
1159 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Compiled the SILC under cygwin. Compiled and tested briefly
1162 without problems. More tests needed. The SIMs didn't compile
1165 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1167 * Fixed possible crash in silc_get_username in the
1168 lib/silcutil/silcutil.c.
1170 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Fixed a va_arg in silc/client_ops.c.
1174 * Oops, RC5 routines were named AES and caused some problems
1175 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1177 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Added new SilcIDIP structure into the lib/silccore/id.h and
1180 replaced the old `ip' fields from all SILC ID's to that type.
1181 This is a step towards IPv6 support.
1183 The silc_id_get_len takes now the ID as an extra argument.
1184 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1185 both IPv4 and IPv6 based ID's.
1187 The affected files are lib/silccore/id.[ch] and other files
1188 around the tree using these routines.
1190 * Removed the ID length arguments in server from various
1191 silc_server_send_notify_* routines -> they are not needed
1194 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Fixed memory leak in silc_encode_pem_file in the file
1197 lib/silcutil/silcutil.c.
1199 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1201 * Check minor version as well in the SKE. Affected files are
1202 silcd/protocol.c and lib/silcclient/protocol.c.
1204 * Added --identifier option to the server so that an identifier
1205 can be when creating the public key for the server. Affected
1206 file is silcd/silcd.c.
1208 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1209 lib/silccrypt/silcpkcs.c.
1211 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Register default ciphers and stuff when using -C option with
1214 the server. Affected file sildc/silcd.c.
1216 * Put back the servers public key filename format, it is better
1217 than the new one. For now, the client keys are saved with the
1218 new filename format. The affected file silc/client_ops.c.
1220 * Implemented the Cipher API for the rest of the ciphers that
1221 did not implement it or implemented it the wrong way.
1223 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Register default ciphers and stuff when using the -S option
1226 in the client. Affected file silc/silc.c. Same also when
1227 creating new key pair with -C option.
1229 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Fixed the silc_verify_public_key client operation function to
1232 save the public keys differently. The fingerprint is now
1233 used as filename and not the hostname. This way also the
1234 client keys are saved uniquely and not with hostnames. The
1235 affected file is silc/client_ops.c.
1237 * Trimmed the silc_hash_fingerprint function to remove extra
1238 whitespaces from the end of the fingerprint. The affected
1239 file is lib/silccrypt/silchash.c.
1243 * Added silc_cipher_register_default function to register all
1244 default ciphers. It can be used when configuration files
1245 does not exist and the application does not want any specific
1246 ciphers in any specific order.
1248 The SilcDList is now used as silc_cipher_list dynamically
1249 allocated cipher list. Removed the static list all together
1250 and now all ciphers must be allocated to the dynamic list.
1251 The silc_cipher_alloc routine was changed to check only the
1254 All silc_cipher_* routines that used to return int returns
1257 The affected files lib/silccrypt/silccrypt.[ch].
1259 * The same thing was done to silc_hash_* as for silc_cipher_*
1260 routines. Affected files lib/silccrypt/silchash.[ch].
1262 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1263 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1264 Added also silc_pkcs_[un]register[_default] functions.
1265 Removed the data_context from the PKCS API.
1267 * Added silc_hmac_register_default function to register default
1268 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1269 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1270 to unregister all hmacs at once.
1272 * Register the default ciphers, hash functions, PKCSs and HMACs
1273 if client's configuration file does not exist. The affected
1276 * The client did not load the hash functions from the SIM
1277 modules at all. Added support for this. Affected file is
1278 silc/clientconfig.c.
1280 * When decoding public key with silc_pkcs_public_key_decode, check
1281 the supported algorithm only if PKCS are registered. Affected
1282 file lib/silccrypt/silcpkcs.c. The same was done with the
1283 silc_pkcs_private_key_decode.
1285 * Fixed the SILC List routines to keep the list always in order.
1286 It used to change the list's order when traversing the list but
1287 not it preserves the order. Affected file lib/trq/silclist.h.
1289 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Added the client library to use the SilcSocketConnection's
1292 reference counter (by silc_socket_dup) to prevent the bug that
1293 the socket object may be freed underneath async operation.
1295 * The name resolv library checking fixes in the configure.in.pre.
1298 * Created new version of the protocol drafts for future
1299 development. The -03 drafts are the ones that will be changed
1300 in the trunk now and the -02 will remain as they are.
1302 * Send list of CUMODE notifys to the router when announcing
1303 the channel users to the router. Affected file silcd/server.c.
1304 If the router receiving channel founder CUMODE for a channel
1305 that already has channel founder it will send CUMODE notify
1306 to the sender to remove the channel founder rights from the
1307 announced client. Affected file silcd/packet_receive.c.
1309 * The CUMODE notify may now use Server ID as well as the entity
1310 who changes the mode. Updated protocool specs.
1312 * Updated INSTALL and README files.
1314 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * New web pages in the http://silc.pspt.fi. The pages was
1321 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Implemented the [DenyConnectin] config section in the server.
1324 Added silc_server_config_denied_conn to check whether incoming
1325 connection is denied. Affected file silcd/serverconfig.[ch].
1327 * Do not check the ports when checking the incoming configuration
1328 data if the port is 0, meaning any. Affected file is
1329 silcd/serverconfig.c.
1331 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1333 * Fixed buffer overflow in silc_string_compare in the file
1334 lib/silcutil/silcutil.c.
1336 * Fixed double free in silc_server_command_leave in the file
1339 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Fixed the version checking in the server. Affected file is
1344 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Fixed the configuration data fetching when accepting new
1347 connections in the server. Affected file silcd/server.c.
1349 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Added `sender_entry' argument to the function
1352 silc_server_packet_relay_to_channel so that we can check
1353 whether some destination actually belongs to the same route
1354 the sender belongs (ie, we must not resend the packet to the
1355 sender). Affected file silcd/packet_send.[ch].
1357 * Added `servername' field to the SilcClientEntry in the server
1358 to hold the name of the server where client is from. Affected
1359 file is silcd/idlist.h.
1361 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Moved the channel message encrypting in the router betwen
1364 router connections from silc_server_channel_message to the
1365 silc_server_packet_relay_to_channel since we want to check
1366 whether we have anybody channel before encrypting anything.
1367 Affected files silcd/packet_[receive/send].c.
1369 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Fixed the [AdminConnection] server config section to support
1372 multiple entries. Affected file silcd/serverconfig.c.
1374 * Added support into the server to check the validity of the
1375 incoming connection before executing any KE or authentication
1378 * The connection configuration is now saved to the KE and
1379 connection auth protocol contexts and not fetched anymore in
1380 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1382 * The local hosts listenning address and port is also resolved
1383 now when starting the server. We want to have the socket object
1384 to include the real address and port for the listener. Added
1385 new function silc_net_check_local_by_sock into the files
1386 lib/silcutil/silcnet.[ch].
1388 * Fixed a broadcast bug in server -> do not broadcast if we
1391 * Fixed a routing bug. Do not route broadcast packets ever.
1392 Broadcast packets must be processed always and not routed since
1393 they may be destined to some other host than yourself and thus
1394 would get routed without no good reason. Affected file is
1397 * Added function silc_server_config_is_primary_route to check
1398 whether primary router connection has been configured (a router
1399 configuration that we are initiating). If there is not, we
1400 will assume that there is only two routers in the SILC network
1401 and we will use the incoming router connection as our primary
1402 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1404 * Changed the order of the broadcasting. Broadcast _after_ the
1405 packet has been processed not before. Affected file is
1408 * Fixed a [ClientConnection] parsing bug. The port was never
1409 parsed correctly thus resulting to port 0. Affected file
1410 silcd/serverconfig.c.
1412 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1413 argument and did not set the broadcast packet flag. Affected
1414 file silcd/packet_send.c. Fixed same bug in the function
1415 silc_server_send_notify as well.
1417 * If we receive NEW_ID packet for our own ID in the server, ignore
1420 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Removed the nickname from the Private Message Payload.
1425 Updated the code and the protocol specs.
1427 * Updated protocol specs for submitting to the IETF.
1429 * Tweaked the Random Number Generator a bit. Affected file
1430 lib/silccrypt/silcrng.c. Exported a new function
1431 silc_rng_[global]_add_noise which can be used to add more
1434 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Do not parse packets with different timeout when protocol
1437 is active -> may cause problem with rekey. Affected file
1440 * When server receives signoff notify it must not create
1441 new channel key if the client is on any channels since the
1442 sender of the signoff notify will create it.
1444 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Added printing of error messages during SKE protocol from the
1447 failure packet sent by server during SKE. Affected file
1450 * Removed the client's failure_callback handling with timeout
1451 and handle it immediately when received.
1453 * The SKE library returned wrong type in SUCCESS and FAILURE
1454 packets. They must be 32 bit MSB not 16 bit MSB.
1456 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Ok, rewrote the logic of the re-key and now it seems to work.
1459 I tested it on high traffic with frequent re-keys without
1460 problems. Added hmac_receive (and renamed hmac to hmac_send)
1461 in SilcClientConnection in lib/silcclient/client.h and
1462 in SilcIDListData in silcd/idlist.h. Also, removed the
1463 SilcPacketParserContext's cipher and hmac fields as they are
1464 not needed anymore and actually caused some problems when
1465 the ciphers and hmac's changed underneath the packet parser.
1467 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * If re-key protocol is active then process the incoming packets
1470 synchronously since we must assure that icoming packets encrypted
1471 with the old key is processed before the new keys is set to
1472 use. This is true other packets than for REKEY packets.
1473 Affected file silcd/server.c. The same was done to client library
1474 as well, affected file lib/silcclient/client.c.
1476 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Fixed bug in client and server to accept the force send if
1479 the packet is send from silc_[server/client]_packet_process
1480 function. Otherwise the packets are never delivered, oops.
1482 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Disable force sending of packets when REKEY protocol is active.
1485 We must assure that no packet is sent directly when rekey is
1486 performed. All packets must be sent through packet queue.
1487 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1488 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1489 function is silc_[server/client]_packet_send_real to check
1492 * Replaced the SIM paths from example config files to
1493 /usr/local/modules. Also, make install creates now
1494 /usr/local/silc/logs directory to hold all the SILC server
1497 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Made the configure.in.pre work on Solaris. Patch by salo.
1501 * Made all ciphers compatible with non-x86 machines. Defined
1502 CBC mode macros into lib/silccrypt/ciphers_def.h.
1504 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Fixed the make install.
1508 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * When MAC computation fails the silc_packet_decrypt returned 0
1511 even though it was supposed to return -1. Fixed this. The
1512 affected file is lib/silccore/silcpacket.c.
1514 * Do not replace the config files in /etc/silc (in make install)
1515 if they already exist. Affected file ./Makefile.am.
1517 * Do not send re-key packets immediately but through packet queue.
1518 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1520 * Changed silc_net_check_host_by_sock to return FALSE if the
1521 IP/DNS could not be resolved. Though, it returns the IP address
1522 now even if it could not resolve it (but returns also FALSE).
1523 Affected file lib/silcutil/silcnet.[ch].
1525 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Added silc_pkcs_decode_identifier to decode the public key's
1528 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1529 Added also silc_pkcs_free_identifier. Added also new context
1530 SilcPublicKeyIdentifier.
1532 * Added -S option to the silc client. It is used to dump the
1533 contents of the specified public key file.
1535 * Changed the PKCS api to return the public key length when
1536 setting the public key.
1538 * Fixed a fatal bug in the public and private key file loading.
1539 Affected file lib/silccrypt/silcpkcs.c.
1541 * Execute the packet parsing for client with zero (0) timeout
1542 if the protocol is active. Affected file silcd/server.c.
1544 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Made the key generation options to the silcd program. Added
1547 -C option, equivalent to client's option.
1549 * Added new [ServerKeys] config section to the server. It
1550 configures the server's public and private key.
1552 * Defined generic Public Key Payload into the protocol
1553 specification to send specific type of public keys and
1556 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1557 public key or certificate.
1559 * Implemented the GETKEY command to the server and to the
1560 client library and on user interface.
1562 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Made preliminary `make install' work.
1566 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1568 * Added SilcServerRekey context into silcd/idlist.h.
1570 * Added the PFS support as defined in the specification to the
1571 SKE protocol. Affected files lib/silcske/*.c.

1574 the number of the SKE group that is used with PFS in re-key.
1575 Affected file silcd/idlist.h.
1577 * Added PFS re-key support to the server. Affected file is
1580 * Added silc_protocol_cancel to cancel execution of the next
1581 state of the protocol. Affected file is
1582 lib/silccore/silcprotocol.[ch].
1584 * Added the re-key support with and without PFS to the client
1585 library. Re-key is performed once in an hour, by default.
1587 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1588 Added silc_client_rekey_callback and silc_client_rekey_final.
1589 Affected files are lib/silcclient/protocol.[ch] and
1590 lib/silcclient/client.[ch].
1592 * Removed the `hmac_key' and `hmac_key_len' fields from the
1593 SilcClientConnection structure; not needed. Affected file is
1594 lib/silcclient/client.h.
1598 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Do not ask whether user wants to use the negotiated private key
1601 for private messages, just use it. Affected file is
1602 silc/local_command.c.
1604 * Added `send_enc_key' and `enc_key_len' fields to the
1605 SilcIDListData structure since they are needed in the re-key
1606 phase. Affected file is silcd/idlist.[ch].
1608 * Implemented the simple re-key protocol into the server.

1619 * Adde `pfs' field to the SilcIDListData to indicate whether
1620 the PFS is to be performed in the re-key. Affected file is
1623 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1626 int64 of at least the xintXX size. If void * is less that 4
1627 bytes uint32 * will be used. Defined bool as boolean.
1629 * Changed _ALL_ unsigned long and unsigned int to uint32,
1630 unsgined short to uint16 in the source tree.
1632 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1633 not handle clients that has entry->data.registered == FALSE.
1634 They are not in the network anymore. Affected file is
1637 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Implemented the sending of the SERVER_SIGNOFF notify in the
1640 server. Affected file is silcd/server.c.
1642 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1643 Added also silc_notify_payload_encode_args into the
1644 lib/silccore/silcnotify.[ch].
1646 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1647 Affected file silcd/packet_receive.c.
1649 * Implemented the SERVER_SIGNOFF notify handling in the client
1650 library. Affected file lib/silcclient/client_notify.c. Also,
1651 implemnted the printing of the SERVER_SIGNOFF info to the
1652 application. Affected file silc/client_ops.c.
1654 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1655 if the deleting was successful. Affected file silcd/idlist.[ch].
1657 * Added support for public key authentication in the connection
1658 authentication protocol in the client library. Affected file
1659 lib/silcclient/protocol.c.
1661 * Changed the server's silc_idlist_get_clients_by_* interface
1662 to support already allocated array so that new entries may be
1663 added to pre-allocated array. Affected file silcd/idlist.[ch].
1664 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1665 and command replies.
1667 * All command reply functions in the server now calls the
1668 pending command callback even if error occured. This way the
1669 error will be delivered to the client as well. Affected files
1670 silcd/command.c and silcd/command_reply.c.
1672 * Fixed INFO command to return local server's info if no server
1673 was provided. Affected file lib/silcclient/command.c.
1675 * Removed RESTART command for good. Updated the code and the
1678 * Rewrote parts of the task system. It is a bit simpler now.
1679 Removed unsued task priorities. The affected files are
1680 lib/silcutil/silctask.[ch].
1682 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Moved the USERS printing from the library to the application.
1685 Affected files lib/silcclient/command.c and silc/client_ops.c.
1687 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1691 * Added channel key re-key support. The re-key is perfomed
1692 only by the router and is done once in an hour. Added `rekey'
1693 field to the SilcChannelEntry in the server. Affected files
1694 silcd/server.c and silcd/idlist.h.
1696 * Added silc_task_unregister_by_context into the file
1697 lib/silcutil/silctask.[ch].
1699 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Added SILC_UMODE_GONE mode to indicate when the client is not
1702 present in the SILC network. Added also support to the local
1703 command AWAY that will set this mode. Added support of showing
1704 "xxx is gone" in WHOIS command. The USERS command shows the
1705 gone status as well.
1707 * Fixed setting server and router operator privileges in the
1708 server's UMODE command. Affected file silcd/command.c.
1710 * Merged the SKE KE1 and KE2 payloads into one payload. The
1711 new KE payload is equivalent to the old KE2 payload.
1713 Cleaned up the SKE Start Payload parsing. It now uses the
1714 simple buffer unformatting to do the parsing. A lot faster
1717 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1718 to the SKE that is used to indicate whether both of the SKE
1719 parties should perform authentication. By default only the
1720 responder performs authentication. By setting this flag also
1721 the initiator must do authentication. By default it is unset
1722 since in normal SKE case, client to server connection, only
1723 the responder should do authentication. When doing SKE between
1724 two clients both should perform authentication. Updated the
1725 code and the protocol specs.
1727 * A little fix to IDENTIFY command in the server. Search the
1728 client first by hash not nickname. Affected file is
1731 * Fixed the silc_client_close_connection to support closing
1732 the client to client connections wihtout deleting too much
1733 data. Affected file lib/silcclient/client.c.
1735 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1736 are received if protocol used to be active but is not anymore
1737 the application would crash due to NULL pointer dereference.
1738 Affected files silcd/server.c and lib/silcclient/client.c.
1740 * Added `hash' field to the SilcClientConnection to include
1741 the hash function negotiated in the SKE protocol.
1743 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1744 to set the channel founder authentication data. A client can
1745 claim the founder rights later by providing the authentication
1746 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1747 This way the channel founder can regain the channel founder
1748 privileges even it is left the channel. This works only on
1749 local server and the client must be connected to the same
1750 server to be able to regain the founder rights. Updated the
1751 protocol specs accordingly.
1753 Added support to the CMODE command in the client to set the
1754 founder auth data. Read the README to see how to set it.
1756 Added support to the CUMODE command to claim the founder
1757 rights. Read the README to see how to do it.
1759 Added support for the founder authentication to the Channel
1760 Entry in the server. Affected file silcd/idlist.h.
1762 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1763 server's CMODE command. Affected file silcd/command.c.
1765 * Added the following new functions into lib/silccore/silcauth.[ch]:
1766 silc_auth_get_method and silc_auth_get_data.
1768 * The server now saves the remote hosts public key to the
1769 SilcIDListData pointer. Affected file silcd/protocol.c.
1771 * The normal server now does not remove the channel entry from
1772 the cache if the founder authentication data is set. It used
1773 to remove it if the founder was the last one on the channel on
1774 the server and left the channel. The auth data is saved and
1775 if the channel is re-joined later the old entry is used with
1776 the old auth data. Affected files silcd/command_reply.c and
1779 * Removed the `pkcs' field from the SilcIDListData structure
1780 in the server; it is not used. Affected file silcd/idlist.h.
1782 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Fixed packet processing on slow links. Partial packets were
1785 never re-processed because the incoming data buffer was cleared
1786 by the application. Application must not directly clear the
1787 sock->inbuf, the packet processing routines handle it. Fixed
1788 this in client library and in server.
1790 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Fixed the WHOIS and IDENTIFY send reply function to really
1793 check whether to send list or just one entry. Affected file
1796 * Cleaned up the LEAVE command's channel key distribution. The
1797 affected file silcd/command.c.
1799 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1800 can enforce the channel mode as well. In that case the ID
1801 includes the ID of the server. The code now enforces the
1802 mode change if the router have different mode than the server.
1804 * The notify client operation with CMODE_CHANGE notify can now
1805 return NULL client_entry pointer if the CMODE was not changed
1806 by client. Application must check for this.
1808 * Added <Server ID> argument to INFO command to support server
1809 info fetching by Server ID.
1811 * Added silc_server_announce_get_channel_users to get assembled
1812 packets of channel users of the specified channel. Affected
1813 file silcd/server.[ch].
1815 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1816 was freed underneath the ID Cache.
1818 * Re-announce clients when the server received CHANNEL_CHANGE
1819 notify from the router. Affected file silcd/packet_send.c.
1821 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1823 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1824 crashed since it did not handle the fact that there is no cipher
1825 called "3" and didn't check the error condition. Now fixed.
1827 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1828 flag. It can be used to send message requests.
1830 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * Implemented the RESTART command in the client.
1834 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1835 notice type messages. Added notice printing to the user
1838 * The channel keys are not re-generated if the channel's mode
1839 is PRIVKEY, ie private key on the channel exists. Affected
1840 files silcd/server.c and silcd/command.c.
1842 * Fixed a little bug in channel message delivery when channel
1843 private keys are set in the server. Affected file is
1844 silcd/packet_send.c.
1846 * Changed the setting on channel->on_channel = TRUE from the
1847 silc_client_save_channel_key to the JOIN command reply. The
1848 key payload is not received if the private channel key is set.
1849 Affected file lib/silcclient/command_reply.c and the
1850 lib/silcclient/client_channel.c.
1852 * When the CMODE_CHANGE notify is sent and the channel private
1853 key mode is removed the channel key must be re-generated in
1854 other cells as well. Added this support for the router in the
1855 silcd/packet_receive.c.
1857 * Added new local command NOTICE to send notice message on
1858 channel. Affected file silc/local_command.[ch].
1860 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Added new local command ME to the client. It is used to send
1863 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1864 some action. Affected file silc/local_command.[ch].
1866 * Changed channel_message and private_message client operations
1867 to deliver the message flags to the application. Added also
1868 the `flags' arguments to the silc_client_send_channel_message
1869 and silc_client_send_private_message functions. Affected file
1872 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Redefined the Private Message Payload to support private message
1875 keys and to support the new private message flags. Updated
1876 the protocol specs. Flags makes it possible to have for example
1877 CTCP style messages.
1879 * Added new type SilcPrivateMessagePayload and defined an API
1880 for it in the lib/silcclient/silcprivate.[ch].
1882 * Tested private message private keys successfully. Tested the
1883 private message key set, unset and list commands with the new
1886 * Redefined the Channel Message Payload to include the channel
1887 message flags (equal with private message flags) to support
1888 for example CTCP style messages.
1890 * Defined some of the message (for channel and private message)
1891 flags. Updated the protocol specs and added the flags to the
1892 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1894 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Added SilcKeyAgreementStatus type to the key agreement routines
1897 to indicate the current status and error if one occured.
1898 The status types are defined in the lib/silcclient/silcapi.h.
1900 * Added new local command KEY that is used to set and unset private
1901 keys for channels, set and unset private keys for private messages
1902 with remote clients and to send key agreement requests and
1903 negotiate the key agreement protocol with remote client. The
1904 key agreement is supported only to negotiate private message keys,
1905 it currently cannot be used to negotiate private keys for channels,
1906 as it is not convenient for that purpose.
1908 * Fixed a minor pending callback setting bug in the function
1909 silc_client_get_client_by_id_resolve, now the function works.
1910 Affected file lib/silcclient/idlist.c.
1912 * Added function silc_net_get_local_port to get local bound
1913 port by socket. Added to lib/silcutil/silcnet.[ch].
1915 * Added `sockets' and `sockets_count' fields to the SilcClient
1916 object. They hold the sockets of the listenning sockets in
1917 the client. Listenning sockets may be for example the key
1918 agreement server. Affected file lib/silcclient/client.[ch].
1919 Added functions the silc_client_add_socket and the
1920 silc_client_del_socket. They are exported to the application
1923 * Added ~./silc/clientkeys to support other client's public keys.
1925 * Renamed verify_server_key client operation to verify_public_key
1926 and added one argument to indicate the type of the connection
1927 (server, client etc.).
1929 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1931 * Added silc_server_connection_auth_request to handle the
1932 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1933 silcd/packet_receive.[ch].
1935 * Added silc_server_send_connection_auth_request into the
1936 silcd/packet_send.c to send the connection auth request packet.
1938 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1941 * Fixed the public key authentication in responder side in the
1942 server. The `auth_data' pointer includes the SilcPublicKey
1943 not the path to the public key. Affected file silcd/protocol.c.
1945 * Implemented the public key authentication in the initiator side
1946 in the server. Affected file silcd/protocol.c.
1948 * Removed the [RedirectClient] config section from the server
1949 configuration. Is not needed and I don't want to implement it.
1951 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Cleaned up the CMODE command in the server. It now works
1954 correctly and supports all the modes defined in the protocol.
1955 Affected file is silcd/command.c.
1957 * Added `hmac_name' field to the SilcChannelEntry in the server
1958 to hold the default HMAC of the channel. It can be set when
1959 creating the channel (with JOIN command). Affected files
1962 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1963 type to indicate the change of the current cipher and hmac
1964 on the channel. Client can safely ignore the <cipher> argument
1965 (if it chooses to do so) since the CHANNEL_KEY packet will
1966 force the channel key change anyway. The <hmac> argument is
1967 important since the client is responsible of setting the new
1968 HMAC and the hmac key into use.
1970 * Fixed the CMODE command in the client library as well.
1972 * Tested CMODE command in router environment successfully.
1974 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Show the version of the remote client (or server) when connecting
1977 to the server. It is logged to the log file. Affected file
1978 is silcd/protocol.c.
1980 * Fixed the KILLED notify handling in the client library. The
1981 client must be removed from all channels when receiving the
1984 Also, do not remove the client entry when giving the KILL
1985 command but when the KILLED notify is received.
1987 * Removed silc_idlist_find_client_by_nickname from the server.
1988 Not needed anymore. Affected files silcd/idlist.[ch].
1990 * Implemented the CHANNEL_CHANGE notify type handling to the
1991 server. Affected file silcd/server.c.
1995 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Added silc_server_send_notify_invite to send the INVITE
1998 notify between routers.
2000 * Implemented the INVITE command correctly to the server.
2002 * Implemented the INVITE notify type handling in the server.
2004 * Implemented the INVITE command to the client library and on the
2007 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Added function silc_server_get_client_resolve to find the
2010 client entry by ID from all ID lists and then resolve it
2011 (using WHOIS) if it cannot be found. Affected file is
2014 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Implemented the BAN command to the client library.
2018 * The JOIN command in the server now checks the invite list
2021 * Changed the silc_command_reply_payload_encode_va and the
2022 silc_command_payload_encode_va to support that if argument is
2023 NULL it ignores and checks the next argument. Affected file
2024 lib/silccore/silccommand.c.
2026 * Added silc_server_send_notify_ban to send the BAN notify
2027 type between routers.
2029 * Chaned the silc_notify_payload_encode to support that if
2030 argument is NULL it ignores and checks the next argument.
2031 Affected file lib/silccore/silcnotify.c.
2033 * Tested ban lists in router environment successfully.
2035 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Implemented BAN command to the server, in silcd/command.[ch].
2039 * Removed the BAN and INVITE_LIST modes from the CMODE command
2042 * Added function silc_string_match to regex match two strings.
2043 Affected files lib/silcutil/silcutil.[ch].
2045 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Redefined parts of the SilcChannelEntry in the server to support
2048 the new ban and invite lists.
2050 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Redefined the INVITE command. The same command can be used to
2053 invite individuals to the channel but also to manage the invite
2054 list of the channel (to add to and remove from the invite list).
2055 Updated the protocol specs.
2057 * Added new command SILC_COMMAND_BAN that can be used to manage
2058 the ban list of the channel. Updated the protocol specs.
2060 * Removed the channel modes: the SILC_CMODE_BAN and the
2061 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2062 in the CMODE command. The equivalent features are now available
2063 using INVITE and BAN commands. Updated the protocol specs.
2065 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2066 in the network about change in the current ban list. The notify
2067 type is not used by the client.
2069 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2070 support the invite lists.
2072 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * Added new function silc_string_regexify that converts string
2075 including wildcard characters into regex string that can
2076 be used by the GNU regex library. Added into the file
2077 lib/silcutil/silcutil.[ch].
2079 Added silc_string_regex_combine to combine to regex strings
2080 into one so that they can be used as one regex string by
2081 the GNU regex library. Added into the file
2082 lib/silcutil/silcutil.[ch].
2084 Added silc_string_regex_match to match two strings. It returns
2085 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2087 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2089 * Imported GNU regex to the soruce tree into lib/contrib.
2090 Fixed some compiler warning from the regex.c.
2092 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2094 * Fixed MOTD command in the server to work in router environment.
2096 * Fixed the MOTD command in the client library to support
2097 the server argument in the command.
2099 * Added `nickname_len' argument to the silc_idlist_add_client
2100 in the server, as the `nickname' argument may be binary data
2103 * Added silc_idlist_get_channels to return all channels from
2106 * Implemented LIST command to the server. Affected file is
2109 * Implemented the LIST command to the client library and on the
2112 * Added [<user count>] argument to the LIST command reply.
2113 With private channels the user count is not shown.
2115 * Updated TODO and README.
2117 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * The client entry's data.registered must be TRUE even with
2120 global client entry on global client list. The data.registered
2121 is used to check whether the client is anymore in the network,
2122 for example with WHOWAS command so it must be valid.
2124 * Fixed the WHOWAS command in the server. It now actually works
2125 in router environment. Added function into silcd/command_reply.c
2126 silc_server_command_reply_whowas_save.
2128 * Added silc_idlist_purge function to the silcd/idlist.c
2129 to periodically purge the ID Cache.
2131 * Fixed INFO command in the server. It works now in router
2132 environment. Added <server name> argument to the INFO command
2133 reply. Updated the protocol specs.
2135 * Fixed minor bug in silc_idcache_purge to not purge if the
2136 expire value is zero.
2138 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2139 they were buggy because of the WHOWAS information.
2141 * Fixed local command MSG to handle the async resolving of
2142 the remote client properly. It used to fail the first MSG.
2143 Affected file silc/local_command.c.
2145 * Added `data_len' field to SilcIDCache context.
2147 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2149 * Update TODO. Todo in commands in the server.
2151 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2154 used by routers as broadcast packet to inform other routers
2155 about the changed user mode.
2157 Implemented the notify handling in the server. Affected file is
2158 silcd/packet_receive.c. Added the function
2159 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2161 * Added new generic Channel Payload and deprecated the New Channel
2162 Payload. The New Channel Payload is now the generic Channel
2165 * Added new argument `mode' to the silc_server_send_new_channel
2166 as it is required in the Channel Payload now.
2168 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2169 and created a new and real SilChannelPayload to represent the
2170 new generic Channel Payload. Implemented the encode/decode
2171 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2173 * Added silc_server_get_client_channel_list to return the list
2174 of channels the client has joined for WHOIS command reply.
2175 Affected file silcd/server.[ch].
2177 * Implemented the channel list sending in the WHOIS command reply
2178 in server and in the client.
2180 Implemented the channel list displaying on the user interface
2181 as well. Affected file silc/client_ops.c.
2183 * Added silc_channel_payload_parse_list to parse list of Channel
2184 Payloads. It returns SilcDList list of SilcChannelPayloads.
2185 Client for example can use this function to parse the list of
2186 channels it receives in the WHOIS command reply. The caller
2187 must free the list by calling silc_channel_payload_list_free.
2188 Affected files lib/silccore/silcchannel.[ch].
2190 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Added one new argument <user mode> to the WHOIS command reply
2193 to return the mode of the user in SILC. Updated the protocol
2196 Implemented it to the server and client.
2198 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Fixed the mode printing on the user interface on joining.
2201 Affected file silc/client_ops.c.
2203 * Implemented the UMODE command and user modes in general to the
2204 client library and to the user interface.
2206 * Implemented the UMODE command to the server.
2208 * The server now sends UNKNOWN_COMMAND error status if client sends
2209 unknown command. Affected file silcd/command.c.
2211 * All server commands now handle the command identifier the right
2212 way when sending the command reply to the client. The client can
2213 use to identify the command replies with the identifier.
2215 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Added silc_server_get_client_route to resolve the route to
2218 the client indicated by the client ID. Affected file is
2221 * Added silc_server_relay_packet as general function to relay
2222 packet to arbitrary destination. This deprecates functions
2223 like _send_private_message_key, _relay_notify etc. Affected
2224 file is silcd/packet_send.[ch].
2226 Removed silc_server_send_key_agreement,
2227 silc_server_send_private_message_key and
2228 silc_server_packet_relay_notify functions from the file
2229 silcd/packet_send.[ch].
2233 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2234 server. Affected file silcd/packet_receive.[ch].
2236 * Implemented the KILL command to the client. Implemented the
2237 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2238 Affected files lib/silcclient/command[_reply].c and
2239 lib/silcclient/client_notify.c. Implemented the KILL notify
2240 printing in the user inteface.
2242 * Fixed a lot silc_parse_nick memory leaks from the client
2243 library in the file lib/silcclient/command.c.
2245 * Changed the silc_server_send_notify_on_channels's `sender'
2246 argument from SilcSocketConnection to SilcClientEntry to
2247 check the sender as entry and not as connection object and not
2248 to send to the client provided as argument. The affected file
2249 is silcd/packet_send.[ch].
2251 * The notify packets that are destined directly to the client used
2252 to not to be processed by the server. Now changed that and the
2253 server processes all notify packets. After relaying the packet
2254 to the client the notify packet is processed in the server.
2256 * The silc_server_free_client_data now checks whether there is
2257 pending outgoing traffic for the client and purges the data to
2258 the network before removing the client entry.
2260 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2263 an client is killed from the SILC Network. Updated the protocol
2266 Added new function silc_server_send_notify_killed to the
2267 silcd/packet_send.[ch].
2269 * Added function silc_server_packet_relay_notify to relay notify
2270 packets that are destined directly to a client. In this case
2271 the server does not process the notify packets but merely relays
2272 it to the client. Affected file silcd/packet_send.[ch].
2274 Added also silc_server_packet_process_relay_notify to check
2275 whereto relay the notify. Affected file is
2276 silcd/packet_receive.[ch].
2278 * Implemented the KILL command to the server.
2282 * Added the backup schema desgined last fall to the protocol
2283 specs for everyone to see. The specification is in the
2284 *-spec-xx.txt draft and the packet type definitions for the
2285 backup routers is in *-pp-xx.txt draft. Thusly, added also
2286 new packet type SILC_PACKET_CELL_ROUTERS.
2288 * A big security problem in the implementation discovered. The
2289 signoff of an client did not cause new channel key generation
2290 which it of course should've done. The channel keys must be
2291 always re-generated when client leaves (or signoffs) the channel.
2292 The silc_server_remove_from_channels funtion now handles
2293 the channel key re-generation.
2295 * Added `sender' argument to the silc_server_send_notify_on_channels
2296 to not to send the client provided as argument. Affected file
2297 silcd/packet_send.[ch].
2299 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2301 * Implemented OPER and SILCOPER commands into the server and
2304 * Added silc_auth_verify and silc_auth_verify_data to verify
2305 the authentication directly from the authentication payload.
2306 It supports verifying both passphrase and public key based
2307 authentication. Affected file lib/silccore/silcauth.[ch].
2309 * Added `hash' field to the SilcIDListData structure. It is the
2310 hash negotiated in the SKE protocol. Affected file is
2313 * Slight redesigning of the SilcAuthPayload handling routines.
2314 Do not send SilcPKCS but SilcPublicKey as argument.
2316 * Implemented the public key authentication support to the
2317 serverconfig. The public key is loaded from the provided path
2318 and saved as authentication data to void * pointer. Thus,
2319 changed the unsigned char *auth_data to void *auth_data;
2321 * Fixed SHUTDOWN command to send the reply before the server
2322 is shutdown. :) Affected file silcd/command.c.
2324 * Fixed fatal bug in CONNECT command. The hostname was invalid
2325 memory and server crashed. Affected file silcd/command.c.
2327 * Fixed fatal bug in CLOSE command. The server_entry became
2328 invalid but was referenced later in the command. Affected file
2331 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Fixed fatal bug in failure packet handling. Server ignored
2334 the failure and thus crashed when it came.
2338 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2341 that the command may be executed only once in (about) 2 seconds.
2342 The old SILC_CF_LAG flag is same but allows command bursts up
2343 to five before limiting.
2345 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2346 server code. Various commands now includes the CF_LAG_STRICT
2347 flag to disallow any kind of miss-use of the command.
2349 * Fixed the silc_buffer_unformat to not to allocate any data
2350 if the length of the data is zero. It used to allocate the
2351 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2353 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Changed the format of AdminConnection configuration section
2356 in the server. Added username of the admin to the format.
2357 Affected files silcd/serverconfig.[ch].
2359 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2360 to return admin configuration data by host, username and/or
2363 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Implemented WHOWAS command to the server. Added the functions:
2367 silc_server_command_whowas_parse,
2368 silc_server_command_whowas_send_reply,
2369 silc_server_command_whowas_from_client and
2370 silc_server_command_whowas_from_server
2372 * Added <Client ID> argument to the WHOWAS command reply. Updated
2373 the protocol specs accordingly.
2375 * Implemented WHOWAS command and command_reply to the client
2378 Implemented the WHOWAS printing on the user interface.
2380 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2382 * Added new argument to the WHOWAS command reply, the real name.
2383 It is an optional argument. Updated the protocol specs.
2385 * Added SilcIDCacheDestructor callback that is registered when
2386 the SilcIDCache is allocated. The callback is called when
2387 an cache entry in the ID Cache expires, or is purged from the
2388 cache. Added into lib/silccore/idcache.[ch].
2390 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2391 to destruct the client entries when the cache entry expires.
2392 Other ID Cache's in server and in the client library ignores
2395 * If the ID Cache entry's `expire' field is zero then the entry
2396 never expires. Added boolean `expire' argument to the
2397 silc_idcache_add function in the lib/silccore/idcache.[ch].
2398 If it is TRUE the default expiry value is used.
2400 * Added silc_server_free_client_data_timeout that is registered
2401 when client disconnects. By default for 5 minutes we preserve
2402 the client entry for history - for WHOWAS command.
2404 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Added support to the server to enforce that commands are not
2407 executed more than once in 2 seconds. If server receives
2408 commands from client more frequently, timeout is registered
2409 to process the commands. Affected file silcd/command.c.
2410 Added new function silc_server_command_process_timeout.
2412 * Changed NICK_NOTIFY handling in client library to check that
2413 if the client's nickname was changed, so there is no need to
2414 resolve anything from the server.
2416 * Removed error printing from the WHOIS and IDENTIFY commands.
2417 If error occurs then it is ignored silently in the client library.
2418 The application, however, may map the received error to
2419 human readable error string. The application currently maps
2420 the NO_SUCH_NICKNAME error to string.
2422 * Made the command status message public to the application. Moved
2423 them from lib/silcclient/command_reply.c to
2424 lib/silcclient/command_reply.h. The application can map the
2425 received command status to the string with the
2426 silc_client_command_status_message function.
2428 * Added check to the server to check that client's ID is same
2429 as the Source ID in the packet the client sent. They must
2432 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Added dist-bzip hook to the Makefile.am to make bzip2
2435 compressed distributions.
2437 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Server now enforces the maximum length for the nickname and
2440 the channel as protocol specification dictates. 128 bytes for
2441 nickname and 256 bytes for channel name.
2443 * Moved the WHOIS printing to the application. The client libary
2444 does not print out the WHOIS information anymore, the application
2445 must do it. Renamed silc_client_command_reply_whois_print to
2446 the silc_client_command_reply_whois_save.
2448 The client's idle time is also sent to the application now, and
2449 the idle is shown on screen.
2451 * Added silc_client_command_reply_identify_save to save the
2452 received IDENTIFY entries.
2454 * Do not check for channel private keys in message sending and
2455 reception if the channel does not have the PRIVKEY mode set.
2456 Affected file lib/silclient/client_channel.c.
2458 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2461 just surfaced after chaning the JOIN procedure.
2463 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Added silc_client_get_clients_by_list to get client entries
2466 from Client ID list, that is returned for example by JOIN
2467 and USERS command replies. The application should use this
2468 function for example when JOIN command reply is received to
2469 resolve the clients already on the channel (library does not
2470 do that anymore as USERS command reply is not used in the JOIN
2471 procedure anymore). Affected files lib/silcclient/silcapi.h and
2472 lib/silcclient/idlist.c.
2474 * JOIN command reply and USERS command reply returns now SilcBuffer
2475 pointers instead of unsigned char pointers when returning
2476 the client list and mode list.
2478 * Added <Client ID> argument to the JOIN command reply, mainly
2479 for the server to identify for which client the command was
2480 originally sent. Updated protocol specs accordingly.
2482 * Added SilcDlist private_key pointer to the SilcChannelEntry
2483 in the client to support the channel private keys. Affected
2484 file is lib/silcclient/idlist.h.
2486 * Added SilcChannelPrivateKey argument to the function
2487 silc_client_send_channel_message so that application can choose
2488 to use specific private ke if it wants to. If it is not provided,
2489 the normal channel key is used, unless private keys are set.
2490 In this case the first (key that was added first) is used
2491 as the encryption key.
2493 * Implemented the support for channel private key handling.
2494 Implemented the following functions:
2496 silc_client_add_channel_private_key,
2497 silc_client_del_channel_private_keys,
2498 silc_client_del_channel_private_key,
2499 silc_client_list_channel_private_keys and
2500 silc_client_free_channel_private_keys
2502 Affected file lib/silcclient/client_channel.c.
2504 * Added the support for the private keys in the channel message
2505 sending and encryption and in the message reception and
2506 decryption. Affected funtions are
2507 silc_client_send_channel_message and silc_client_channel_message.
2509 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Added SKE's key verify callback to the client library's
2512 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2514 * Removed the statement that server (or router) must send USERS
2515 command reply when joining to the channel so that the client
2516 knows who are on the channel. Instead, the client list and
2517 client's mode list is now sent in the JOIN command reply to the
2518 client who joined channel. This is better solution.
2520 * Added function silc_server_get_users_on_channel and function
2521 silc_server_save_users_on_channel to the silcd/server.[ch].
2523 * Removed function silc_server_command_send_users from the
2526 * Do not show topic on the client library anymore. The topic is
2527 sent in the command reply notify to the application and the
2528 application must show the topic now.
2530 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Added client searching by nickname hash into the IDENTIFY and
2533 WHOIS commands in the server as they were clearly missing from
2534 them. Affected file is silcd/command.c.
2536 * Fixed a bug in private message receiving in the client library.
2537 The remote ID was freed and it wasn't supposed, now it is
2540 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * Minor fix to the channel payload; allocate the data area, as it
2543 needs to be of specific length.
2545 * If the key agreement port is zero then the operating
2546 system will define the bound port. Affected files are
2547 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2549 * Added new function silc_channel_payload_decrypt into the file
2550 lib/silccore/silcchannel.[ch].
2552 * Moved the channel message etc, check from silc_packet_decrypt
2553 to applications. The library calls now a generic
2554 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2555 when the packet is either normal or special. This was done to
2556 allow more wide range of checking that was not allowed when
2557 the code was in library. Now applications can do virtually any
2558 checks to the packet and return to the library the decision how
2559 the packet should be processed. Affected files are
2560 lib/silccore/silcpacket.[ch].
2562 Added silc_server_packet_decrypt_check to the server and
2563 silc_client_packet_decrypt_check to the client library.
2565 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2566 to send with specified source and destination information.
2568 * Channel message delivery between routers was broken after the
2569 channel key distribution was fixed earlier. The channel key
2570 was used be to distributed to other routers as well which is not
2571 allowed by the protocol. Now this is fixed and channel keys
2572 really are cell specific and the channel message delivery between
2573 routers comply with the protocol specification.
2575 * Fixed various commands in server to check also the global list
2576 for the channel entry and not just the local list. The affected
2577 file silcd/command.c.
2579 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Added assert()s to buffer formatting and unformatting routines
2582 to assert (if --enable-debug) when error occurs. Affected
2583 file: lib/silcutil/silcbuffmt.c.
2585 * Changed to auto-reconnect to check whether the remote host is
2586 router and register the re-connect timeout if it is. It used
2587 to check that whether we are normal server, but router must do
2588 auto-reconnect with another router as well. Affected file
2591 * Removed the [<key len>] option from CMODE command as the cipher
2592 name decides the key length, nowadays. See the defined ciphers
2593 from the protocol specification.
2595 * Added [<hmac>] option to the CMODE command to define the HMAC
2596 for the channel. Added SILC_CMODE_HMAC channel mode.
2598 * Added [<hmac>] option for the JOIN command so that user can
2599 select which HMAC is used to compute the MACs of the channel
2602 * Added Hmac field to the Channel Message Payload. The integrity
2603 of plaintext channel messages are now protected by computing
2604 MAC of the message and attaching the MAC to the payload. The
2605 MAC is encrypted. Now, it is clear that this causes some
2606 overhead to the size of the packet but rationale for this is that
2607 now the receiver can verify whether the channel message decrypted
2608 correctly and also when private keys are set for the channel the
2609 receiver can decrypt the packet with several keys and check from
2610 the MAC which key decrypted the message correctly.
2612 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2613 lib/silccrypt/silccipher.[ch].
2615 * Added silc_hash_len to return the digest length into the
2616 lib/silcrypt/silchash.[ch].
2618 * Rewrote parts of Silc Channel Payload interface in the
2619 lib/silccore/silcchannel.[ch]. The encode function now also
2620 encrypts the packet and parse function decrypts it.
2622 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Fixed a minor formatting bug in the SKE's key material processing.
2625 It actually might have processed the keys wrong way resulting
2628 * Redefined the mandatory HMAC algorithms and added new algorithms.
2629 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2630 and hmac-md5 truncated to 96 bits. The mandatory is now
2631 hmac-sha1-96. Rest are optional (including the one that used
2632 to be mandatory). Rationale for this is that the truncated HMAC
2633 length is sufficient from security point of view and can actually
2634 make the attack against the HMAC harder. Also, the truncated
2635 HMAC causes less overhead to the packets. See the RFC2104 for
2638 * Added new [hmac] configuration section. The SKE used to use
2639 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2640 is of course wrong. The official names that must be proposed in
2641 the SKE are the ones defined in the protocol specification
2642 (hmac-sha1-96 for example). The user can configure any hmac
2643 using any hash function configured in the [hash] section. At
2644 least, the mandatory must be configured.
2646 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2648 * Added HMAC list to the SKE proposal list. It has now both
2649 hash algorithm list and HMAC list. This makes the protocol
2650 incompatible with previous versions. The SKE now seems to work
2651 the way it is supposed to work, for the first time actually.
2653 * Defined plain Hash algorithms to the protocol specification.
2656 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Implemented support for key agreement packets into the server.
2659 Added functions silc_server_key_agreement and
2660 silc_server_send_key_agreement. Other than these functions,
2661 server has nothing to do with this packet.
2663 * Added support for private message key packets into the server.
2664 Added functions silc_server_private_message_key and
2665 silc_server_send_private_message_key.
2669 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2670 called in the protocol's final callback instead in the END
2671 protocol state. This makes a little more sense and in the same
2672 time in client we can use the same protocol routines for normal
2673 key exchange and to key agreement packet handling as well.
2675 * Added to both client's and server's KE protocol context the
2676 SilcSKEKeyMaterial pointer to save the key material. We will
2677 bring the key material to the protocol's final callback by doing
2678 this. The final callback must free the key material.
2680 * Added SKE's packet_send callback into client's KE protocol
2681 context so that the caller can choose what packet sending function
2682 is used. This way we can use different packet sending when
2683 doing normal SKE when doing key agreement packet handling (in
2684 the key agreement packet handling we do not want to encrypt
2687 * Implemented the responder side of the key agreement routines
2688 in the client. The client can now bind to specified port and
2689 accept incoming key negotiation. The key material is passed
2690 to the application after the protocol is over.
2692 * Implemented the processing of incoming Key Agreement packet
2693 in the client. Added function silc_client_key_agreement to
2696 * Implemented the intiator side of the key agreement routines
2697 in the client. The client can now initiate key agreement with
2698 another remote client. The key material is passed to the
2699 application after the protocol is over.
2701 * Created client_keyagr.c to include all the key agreement
2704 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2705 SILC_TASK_CALLBACK except that it is not static.
2707 * Created client_notify.c and moved the Notify packet handling
2708 from the client.[ch] into that file.
2710 * Created client_prvmsg.c and moved all private message and
2711 private message key routines from the client.[ch] into that file.
2713 * Create client_channel.c and moved all channel message and
2714 channel private key routines from the client.[ch] into that file.
2716 * Changed silc_client_get_client_by_id_resolve to resolve with
2717 WHOIS command instead of IDENTIFY command, in the file
2718 lib/silclient/idlist.c.
2720 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Implemented the SKE's responder side to the Client library.
2724 * When FAILURE is received to the protocol do not trust it
2725 blindly. Register a timeout to wait whether the remote closes
2726 the connection as it should do it, only after that process the
2727 actual failure. This was changed to both client and server.
2729 * Added client_internal.h to include some of the structures
2730 there instead of client.h in lib/silcclient/.
2732 * Added function silc_task_unregister_by_callback to unregister
2733 timeouts by the callback function.
2735 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Some "Incomplete WHOIS info" errors has been appearing on the
2738 log files. Took away the entry->userinfo check from WHOIS
2739 reply sending. The entry->userinfo is now " " if client did not
2740 provide one. I thought this was fixed earlier but something
2741 is wrong still. Let's see if the error still appears.
2743 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Fixed a minor bug in the login when the channel key is
2746 re-generated in the server. It used to generate the key in
2747 wrong order and thus caused problems in the channel traffic.
2749 * Fixed a minor bug in channel key distsribution after
2750 KICK command. The key was not sent to the router even though
2753 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * Added silc_ske_process_key_material_data as generic routine
2756 to process any key material as the SILC protocol dictates. The
2757 function is used by the actual SKE library but can be used by
2758 applications as well. This relates to the private message keys
2759 and the channel private keys since they must be processed the
2760 same way the normal SILC session keys. The protocol dictates
2761 this. Affected files: lib/silcske/silcske.[ch].
2763 Added also silc_ske_free_key_material to free the
2764 SilcSKEKeyMaterial structure.
2766 * Defined silc_cipher_set_key function to set the key for
2767 cipher without using the object's method function. The affected
2768 files: lib/silccrypt/silccipher.[ch].
2770 * Implemented silc silc_client_add_private_message_key,
2771 silc_client_add_private_message_key_ske,
2772 silc_client_del_private_message_key,
2773 silc_client_list_private_message_keys and
2774 silc_client_free_private_message_keys functions in the
2777 Added functions silc_client_send_private_message_key to send
2778 the Private Message Key payload and silc_client_private_message_key
2779 to handle incoming Private Message Key payload.
2781 * Added Cipher field to the Private Message Key payload to set
2782 the cipher to be used. If ignored, the default cipher defined
2783 in the SILC protocol (aes-256-cbc) is used.
2785 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Removed lib/silcclient/ops.h file.
2789 Redefined parts of the SILC Client Library API. Created new
2790 file silcapi.h that deprecates the ops.h file and defines the
2791 published Client Library API. Defined also private message key
2792 API and channel private key API into the file.
2794 This is the file that the application must include from the
2795 SILC Client Library. Other files need not be included by
2796 the application anymore.
2798 * Added new key_agreement client operation callback and also
2799 defined the Key Agreement library API for the application.
2801 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2804 is used by clients to request key negotiation between another
2805 client in the SILC network. If the negotiation is started it
2806 is performed using the SKE protocol. The result of the
2807 negotiation, the secret key material, can be used for example
2808 as private message key.
2810 Implemented the Key Agreement payload into the files
2811 lib/silccore/silauth.[ch].
2813 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2815 * Redefined ciphers for the SILC protocol. Added some new ciphers
2816 and defined the key lengths for the algorithms. Changed the
2817 code accordingly. The default key length is now 256 bits.
2819 * Fixed SKE key distribution function silc_ske_process_key_material
2820 when the key length is more than 128 bits. The default key
2821 length in SILC is now 256 bits.
2823 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2824 to indicate unsupported algorithm.
2826 * Renamed rijndael.c to aes.c and all functions as well.
2828 * Fixed a long standing channel key setting bug in client library.
2829 Weird that it has never surfaced before.
2831 * Fixed bug in channel deletion. If the entire channel is removed
2832 then it must also delete the references of the channel entry
2833 from the client's channel list as the client's channel entry and
2834 the channel's client entry share same memory.
2836 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Implemented CONNECT and SHUTDOWN commands in the client.
2840 * Implemented CLOSE command to the client.
2842 * Added the function silc_idlist_find_server_by_name into the
2843 files silcd/idlist.[ch].
2845 Added the function silc_idlist_find_server_by_conn into the
2846 files silcd/idlist.[ch].
2848 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * DIE command was renamed to SHUTDOWN. Updated the both code
2853 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2854 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2856 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2859 * Added function silc_server_create_connection function to create
2860 connection to remote router. My server implementation actually
2861 does not allow router to connect to normal server (it expects
2862 that normal server always initiates the connection to the router)
2863 so the CONNECT command is only good for connecting to another
2866 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2869 or some other client was kicked from the channel.
2871 Implemented the handling of the notify type to both client
2874 Implemented silc_server_send_notify_kicked to send the KICKED
2875 notify. It is used to send it to the server's primary router.
2877 * Implemented the KICK command into server and client.
2879 * Added `query' argument to the silc_idlist_get_client function
2880 to indicate whether to query the client from server or not if
2883 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2884 to indicate that the client is not channel founder.
2888 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Removed the rng context from SilcPacketContext structure and
2891 changed that the packet routine uses the Global RNG API.
2893 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Added support for quit message that client can "leave" on the
2896 channel when it quits the SILC. It is ditributed inside the
2897 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2899 Added silc_server_free_client_data that will take the
2900 signoff message as argument.
2902 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2904 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Updated parts of the protocol specification to keep it up
2909 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2912 payloads in one packet.
2914 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2915 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2916 use now the new List flag.
2918 * Also deprecated the following packet types: REPLACE_ID,
2919 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2921 * Added list support for Notify packet in server.
2923 * Added silc_server_send_notify_channel_change to send the
2924 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2925 the silc_server_send_replace_id.
2927 * Added silc_server_send_notify_nick_change to send the
2928 NICK_CHANGE notify type. Deprecates the function
2929 silc_server_send_replace_id.
2931 * Added silc_server_send_notify_join to send the JOIN notify type.
2932 Deprecates the function silc_server_send_new_channel_user.
2934 * Added silc_server_send_notify_leave to send LEAVE notify type.
2935 Deprecates the function silc_server_send_remove_channel_user.
2937 * Added silc_server_send_notify_cmode and
2938 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2939 types. Deprecates the silc_server_send_set_mode function.
2941 * Added SERVER_SIGNOFF notify type to indicate that server has
2942 quit. This means that all clients on the channel from that
2943 server will drop. This can be also used when netsplit happens.
2945 Deprecated REMOVE_ID packet type since it is not needed anymore
2948 Added silc_server_send_notify_server_signoff to send the
2949 SERVER_SIGNOFF notify type. Deprecates the function
2950 silc_server_send_remove_id.
2952 Added also silc_server_send_notify_signoff to send the
2953 SIGNOFF notify type.
2955 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2956 SILC protocol from this day on. Changed the protocol
2957 specification as well.
2959 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2960 notify type. It is used between routers to notify about
2961 topic changes on a channel.
2963 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2966 * Partly updated the protocol specification to comply with the
2967 changes now made. It is still though a bit outdated.
2969 * The JOIN notify type now takes one extra argument <Channel ID>.
2970 The packet used to be destined to the channel but now the
2971 JOIN type may be sent as list thus it is impossible to
2972 destine it to any specific channel. By adding this argument
2973 it is again possible.
2975 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Added CREDITS file. The CHANGES and CREDITS file will appear
2978 in the distribution as well.
2980 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2983 types in the server's silcd/packet_receive.c.
2985 * Implemented CMODE and CUMODE to work in router environment.
2987 * Fixed minor encoding and decoding buglet from the
2988 lib/silccore/silcmode.c.
2990 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2993 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2995 * Changed all SilcConfigServer* and silc_config_server* to
2996 SilcServerConfig* and silc_server_config*, respectively.
2999 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Associated the ID (client or server ID) to the Authentication
3002 Payload to avoid any possibility of forging. Updated the
3003 protocol specification and the code accordingly.
3005 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * The RSA key length is now save to the RsaKey context in the
3008 key generation process in lib/silccrypt/rsa.c. The key length
3009 is now used to figure out the maximum size of the block allowed
3010 to be encrypted/signed.
3012 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3013 is equivalent to the silc_mp_mp2bin but does not allocate any
3016 * Changed silc_mp_mp2bin API to take length argument. If it is
3017 non-zero then the buffer is allocated that large. If zero, then
3018 the size is approximated using silc_mp_sizeinbase, which however
3021 * Created Global RNG API which is global RNG that application can
3022 initialize. After initializing, any routine anywhere in the
3023 code (including library) can use RNG without allocating a new
3024 RNG object. This was done to allow this sort of use of the
3025 RNG in code that has no chance to allocate RNG object. All
3026 applications currently allocate this and many routines in the
3027 library use this. Affected file lib/silccrypt/silcrng.[ch].
3029 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3030 it to use the Global RNG API.
3032 * Defined Authentication Payload into protocol specification that
3033 is used during SILC session to authenticate entities. It is
3034 used for example by client to authenticate itself to the server
3035 to obtain server operator privileges.
3037 Implemented this payload into the lib/silccore/silcauth.[ch].
3038 Implemented also routines for public key based authentication
3039 as the new protocol specification dictates.
3041 Moved definitions of different authentication methods from
3042 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3044 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3045 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3046 silc_pkcs_verify_with_hash functions into the file
3047 lib/silccrypt/silcpkcs.[ch].
3049 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * The client entry's userinfo pointer must be always valid.
3052 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3053 will fail since it requires the userinfo. Now, the userinfo
3054 is allocated as "" if actual userinfo does not exist. Actually,
3055 it must exist and it is totally Ok to drop client connections
3056 that does not announce the userinfo. However, we will make
3057 this workaround for now.
3059 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3060 to return the remote port by socket.
3062 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3064 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3065 SILC_SERVER_PENDING_EXEC and added an new macro
3066 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3067 data or when error occurs while processing the pending command.
3069 Added new argument `destructor' into silc_server_command_pending
3070 and to the SilcServerCommandPending object. This destructor is
3071 now called after calling the pending callback or if error occurs
3072 immediately. If error occurs the actual pending callback won't
3073 be called at all - only the destructor. The destructor may be
3074 NULL if destructor is not needed.
3076 All this applies for client library code as well. Similar
3077 changes were made there as well for the pending commands.
3079 In the client, the application must now allocate the
3080 SilcClientCommandContext with the silc_client_command_alloc
3083 * Added reference counter to the SilcServerCommandContext. Added
3084 function silc_server_command_alloc and silc_server_command_dup
3087 Same type of functions added to the client library for the same
3090 * Removed the cmd_ident from IDListData away since it is now
3091 global for all connections. It is the command identifier used
3092 in command sending and with pending commands. The affected file
3095 * Added reference counter to the SilcSocketConnection objecet to
3096 indicate the usage count of the object. The object won't be
3097 freed untill the reference counter hits zero. Currently only
3098 server uses this, and client ignores it. The client must be
3099 set to use this too later. The affected files are
3100 lib/silccore/silcsockconn.[ch]. Added also the function
3101 silc_socket_dup to increase the reference counter.
3103 This was mainly added because it is possible that the socket
3104 is removed underneath of pending command or other async
3105 operation. Now it won't be free'd and proper DISCONNECTING
3106 flags, etc. can be set to avoid sending data to connection that
3107 is not valid anymore.
3109 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3110 the connection. After that it sets SILC_SET_DISCONNECTED.
3111 It is, however, possible that the socket data is not still freed.
3112 The silc_server_packet_process now checks that data is not
3113 read or written to connection that is DISCONNECTED. The socket
3114 get's freed when the reference counter hits zero.
3116 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Changed the client operation API: channel_message operation's
3119 `sender' is now the client entry of the sender, not the nickname
3120 and the `channel' is the channel entry, not the channel name.
3122 In the private_message operation the `sender' is now also the
3123 client entry of the sender not the nickname.
3125 Affected file is lib/silcclient/ops.h and all applications
3126 using the client operations.
3128 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Moved the calling of ops->connect() from connect_to_server_final
3131 into receive_new_id functin since that is the point when the
3132 client is actually allowed to send traffic to network. The
3133 affected file is lib/silcclient/client.c.
3135 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3138 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3139 (if needs broadcasting) instead of broadcasting the packets one
3140 by one which would make a burst in the network traffic.
3142 * Added `broadcast' argument to the functions in silcd/server.[ch]
3143 silc_server_create_new_channel[_with_id] to indicate whether
3144 to send New Channel packet to primary router.
3146 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Added new function into the silcd/server.[ch] files:
3149 silc_server_create_new_channel_with_id to create new channel with
3150 already existing Channel ID.
3152 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3153 lib/silccore/silcpacket.h. This packet is used t send list of
3154 Set Mode payloads inside one packet. Server uses this to set
3155 the modes for the channels and clients on those channels, that it
3156 announced to the router when it connected to it. The protocol
3157 specification has been updated accordingly.
3159 * The silc_server_new_channel did not handle the packet coming
3160 from normal server as it normally does not send that. However,
3161 when it announces its channels it does send it. Implemented
3162 the support for that.
3164 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3165 into the file lib/silccore/id.h.
3167 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Fixed memory leaks in the functions silc_idlist_del_client,
3170 silc_idlist_del_channel and silc_idlist_del_server in the file
3171 silcd/idlist.c. All of those leaked like a sieve.
3173 * Fixed some small memory leaks in the client's function
3174 silc_client_notify_by_server.
3176 * Added functions into silcd/server.c: silc_server_announce_clients,
3177 silc_server_announce_channels and silc_server_announce_server.
3178 These functions are used by normal and router server to announce
3179 to its primary router about clients, channels and servers (when
3180 router) that we own. This is done after we've connected to the
3183 These functions effectively implements the following packet types:
3184 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3185 and SILC_PACKET_NEW_ID_LIST.
3187 * Added new functions into the silcd/packet_receive.[ch]:
3188 silc_server_new_id_list, silc_server_new_channel_list and
3189 silc_server_new_channel_user_list to handle the incoming
3190 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3192 * Added support of changing Channel ID in the function
3193 silc_server_replace_id. If the server that announces a channel
3194 to the router already exists in the router (with same name but
3195 with different Channel ID), router is responsible to send
3196 Replace ID packet to the server and force the server to change
3197 the Channel ID to the one router has.
3199 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3200 client that the Channel ID has been changed by the router. The
3201 normal server sends this to the client. Client must start using
3202 the new Channel ID as the channel's ID.
3204 Implemented handling of this new type into lib/silcclient/client.c
3205 into the function silc_client_notify_by_server.
3207 * Added new function silc_idlist_replace_channel_id into the files
3208 silcd/idlist.[ch] to replace the Channel ID.
3210 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Call silc_server_command_identify_check always when processing
3213 the IDENTIFY command in silcd/command.c
3215 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3218 send keepalive packets. The packet can be sent by clients,
3219 servers and routers.
3221 Added function silc_socket_set_heartbeat into the file
3222 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3223 If not set, the heartbeat is not performed. The actual
3224 heartbeat is implemented in the low level socket connection
3225 library. However, application is responsible of actually
3228 Added silc_server_send_heartbeat to send the actual heartbeat
3229 packet into silcd/packet_send.[ch]. Server now performs
3230 keepalive with all connections.
3232 * Added silc_task_get_first function into lib/silcutil/silctask.c
3233 to return the timeout task with shortest timeout. There was a bug
3234 in task unregistration that caused problems. TODO has been
3235 updated to include that task system must be rewritten.
3237 * The client library will now resolve the client information when
3238 receiving JOIN notify from server for client that we know but
3239 have incomplete information.
3241 * Rewrote parts of silc_server_remove_from_channels and
3242 silc_server_remove_from_one_channel as they did not remove the
3243 channel in some circumstances even though they should've.
3245 * Encryption problem encountered in server:
3247 The LEAVE command used to send the Channel Key packet to the
3248 router immediately after generating it. However, the code
3249 had earlier sent Remove Channel user packet but not immediately,
3250 ie. it was put to queue. The order of packets in the router
3251 was that Channel Key packet was first and Remove Channel User
3252 packet was second, even though they were encrypted in the
3253 reverse order. For this reason, MAC check failed. Now, this
3254 is fixed by not sending the Channel Key packet immediately but
3255 putting it to queue. However, this is more fundamental problem:
3256 packets that are in queue should actually not be encrypted
3257 because packets that are sent immediately gets encrypted
3258 actually with wrong IV (and thus MAC check fails). So, packets
3259 that are in queue should be encrypted when they are sent to
3260 the wire and not when they put to the queue.
3262 However, the problem is that the current system has not been
3263 designed to work that way. Instead, the packet is encrypted
3264 as soon as possible and left to the queue. The queue is then
3265 just purged into wire. There won't be any fixes for this
3266 any time soon. So, the current semantic for packet sending
3269 o If you send packet to remote host and do not force the send
3270 (the packet will be in queue) then all subsequent packets to the
3271 same remote host must also be put to the queue. Only after the
3272 queue has been purged is it safe again to force the packet
3275 o If you send all packets immediately then it safe to send
3276 any of subsequent packets through the queue, however, after
3277 the first packet is put to queue then any subsequent packets
3278 must also be put to the queue.
3280 Follow these rules and everything works fine.
3282 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Added new function silc_server_remove_clients_by_server to
3285 remove all client entries from ID list when the server connection
3286 is lost. In this case it is also important to invalidate all
3287 client entires as they hold the invalid server entry. This
3288 fixes fatal bug when server has lost connection and will reconnect
3291 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Made some sanity checks to silc_server_daemonise like to check
3294 whether the requested user and group actually exists.
3296 * Added sanity check to SKE's silc_ske_responder_finish to check
3297 that the public and private key actually is valid.
3299 * Invalidate the client's nickname when receiving Replace ID
3300 packet and the Client ID is being replaced. This means that the
3301 server will query the nickname if someone needs it (client)
3304 * Sort the ID Cache in client library when the ID Cache data
3305 has changed (needs sorting).
3307 * Do not allow for SILC client to create several connections to
3308 several servers. The client does not support windows right now
3309 and generating multiple connections causes weird behaviour.
3311 Irssi-silc client does support windows and can handle several
3312 connections without problems, see: www.irssi.org and SILC plugin.
3314 * Fixed some places where client was added to the IDList. The
3315 rule of thumb is following (in order to get everything right):
3316 If the client is directly connected local client then the
3317 `connection' argument must be set and `router' argument must be
3318 NULL to silc_idlist_add_client function. If the client is not
3319 directly connected client then the `router' argument must
3320 bet set and the `connection' argument must be NULL to the
3321 silc_idlist_add_client function.
3323 * The funtion silc_server_packet_send_local_channel actually did
3324 not check whether the client was locally connected or not. It
3325 does that now. Fixed a bug related to LEAVE command.
3327 * Fixed Remove Channel User payload parsing bug in server's
3328 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3330 * The server's silc_server_save_channel_key now checks also the
3331 global ID list for the channel as it might not be in the local
3332 list. Fixed a bug related to LEAVE command.
3334 * Is this the end of the [<unknown>] buglet that has been lurking
3335 around for a long time? A little for loop fix in server's
3336 silc_server_command_whois_parse that is used by both IDENTIFY
3337 and WHOIS command. At least, this was a clear bug and a cause
3338 of one type of [<unknown>] buglet.
3340 * WHOIS and IDENTIFY commands call the function
3341 silc_server_command_[whois/identify]_check function even if
3342 we are not router server.
3344 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Added --with-gmp configuration option. If set the GMP
3347 is always compiled in the SILC source tree. If not set then
3348 it is checked whether the system has the GMP3 installed. If
3349 it has then the GMP won't be compiled (the system's headers
3350 and library is used), if it doesn't have it then the GMP is
3351 compiled in the SILC source tree.
3353 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Changed RSA private exponent generation to what PKCS #1
3356 suggests. We try to find the smallest possible d by doing
3357 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3358 not security fix but optimization.
3360 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added new config entry [Identity] to fork the server and run
3363 it as specific user and group. A patch from Bostik.
3365 * Imported Dotconf configuration library into lib/dotconf.
3366 This will be used to create the SILC configuration files later.
3367 It will appear in the distsribution after this commit.
3369 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * A big code auditing weekend happening. Auditing code for
3372 obvious mistakes, bugs and errors. Also, removing any code
3375 Removed files for being obsolete:
3377 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3378 inline in the file lib/silcutil/silcbuffer.h)
3380 o lib/silcutil/silcbufutil.c (the header has inline versions)
3382 Changed code to fix possible error conditions:
3384 o The buffer formatting routines now check that the destination
3385 buffer really has enough space to add the data. This applies for
3386 both buffer formatting and unformatting
3387 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3388 unformatting was changed to accomodate following rules:
3389 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3390 sent to the function while XXX_*STRING will not allocate or copy
3391 the data into the buffer. Instead it sets the pointer from the
3392 buffer into the pointer sent as argument (XXX_*STRING used to
3393 require that the pointer must be allocated already). This change
3394 makes this whole thing a bit more consistent and more optimized
3395 (note that the data returned in the unformatting with XXX_*STRING
3396 must not be freed now). The routines return now -1 on error.
3398 o Tried to find all code that use buffer_format and buffer_unformat
3399 and added return value checking to prevent formatting and
3400 especially unformatting errors and possible subsequent fatal
3403 o Changed ske->x and ske->KEY to mallocated pointers in
3404 lib/silcske/silcske.h. Fixed possible data and memory leak.
3406 o Added return value checking to all *_parse* functions. Fixed
3407 many memory leaks as well.
3409 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3410 so that buffer overflows would not happen. All code now also
3411 checks the return value as it can fail.
3413 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added reconnection support to server if the normal server looses
3416 its connection to the router (for example if router is rebooted).
3417 The server performs normal reconnection strategy implemented
3418 to the server. Affected file silcd/server.c.
3420 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Added new packet type SILC_PACKET_SET_MODE that is used to
3423 distribute the information about changed modes (for clients,
3424 channels and clients channel modes) to all routers in the
3425 network. Updated the protocol specification accordingly.
3427 Added functions into silcd/packet_send.c and
3428 silcd/packet_receive.c: silc_server_send_set_mode,
3429 silc_server_set_mode.
3431 Added new files silcmode.[ch] into lib/silccore that implements
3432 the encoding and decoding of Set Mode Payload. Added new type
3433 SilcSetModePayload. Moved the definitions of different modes
3434 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3436 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Oops, a little mistake in server's connection authentication
3439 protocol. The protocol is not ended with FAILURE but with
3440 SUCCESS if the authentication is Ok. :) Affected file is
3443 * Implemented NICK_CHANGE notify handling in server in the file
3444 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3445 the local clients on the channel. After the changing nickname
3446 in router environment snhould work and the [<unknown>] nickname
3447 should appear no more.
3449 The silc_server_replace_id function that receives the Replace ID
3450 payload now sends the NICK_CHANGE notify type also in the file
3451 silcd/packet_receive.c
3453 * Changed WHOIS and IDENTIFY command to support the maximum amount
3454 of arguments defined in protocol specs (3328 arguments). This
3455 fixed a bug that caused problems when there were more than three
3458 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added extra parameter, command identifier, to the
3461 silc_client_send_command so that explicit command identifier
3464 Changed that ID list routines uses specific command identifier
3465 when sending WHOIS/IDENTIFY requests to the server so that they
3466 can be identified when the reply comes back.
3468 Affected files lib/silcclient/command.[ch],
3469 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3471 * Added `sender' argument to silc_server_packet_send_to_channel
3472 to indicaet the sender who originally sent the packet to us
3473 that we are now re-sending. Ignored if NULL. Affected file
3474 silcd/packet_send.[ch].
3476 * Added some server statistics support in silcd/server_internal.h
3477 SilcServerStatistics structure and around the server code. Also
3478 send some nice statistics information when client is connecting
3481 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Fixed channel ID decoding in server's JOIN command reply in
3484 silcd/command_reply.c
3486 * Fixed braodcasting of replace ID payload to not to send it if
3487 we are standalone server in silcd/packet_receive.c.
3489 * Fixed all channel message sending routines to not to send
3490 packets to clients that has router set, since they are routed
3491 separately in the same function earlier. Affects file
3492 silcd/packet_send.c and all channel packet sending functions.
3494 * In USERS reply, res_argv[i] are not allocated, the table
3495 is allocated. Thus changed that free the table, not its
3498 * In server's whois_check and identify_check if the client is
3499 locally connected do not send any WHOIS commands - they are not
3502 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Fixed some minor bugs in client when sending WHOIS command. The
3505 arguments was in wrong order.
3507 * Removed statis function add_to_channel from server in
3508 silcd/command.c that was previously used with the joining but
3511 * Tested USERS command in router environment successfully with two
3512 routers, two servers and two clients.
3514 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Reorganized the USERS command and command reply in client library
3517 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3518 When the command is given by user we register a pending command
3519 callback that will reprocess the command after the reply has been
3520 received from the server. When reprocessing the packet we then
3521 display the information. Thus, the USERS information is displayed
3522 now in the command callback instead of in the command reply
3523 callback. The processing of the command is same as previously
3524 when server has sent the command reply in the JOINing process.
3526 * Added to USERS command in silcd/command_reply.c to join the client,
3527 we didn't use to know about, to the channel after we've created
3528 a client entry for it. Also, for clienet we did know already still
3529 check whether it is on the channel or not and add it if not.
3531 * Removed silc_server_command_join_notify as the function and its
3534 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Changed the client's pending command handling to the same as the
3537 server's pending command handling. It is also now possible to
3538 execute command reply functions from other command reply
3539 function as the function callbacks for commands and command
3540 replies are one and same. The pending commands are not static
3541 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3542 in client connection context. Thus, pending commands are server
3543 connection specific as it is convenient.
3545 Changed the function silc_client_command_pending and
3546 silc_client_command_pending_del and added new function
3547 silc_client_command_pending_check. Removed the
3548 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3551 * Added cmd_ident, current command identifier, to the client
3552 connection context in lib/silcclient/client.h to keep track on
3553 command identifiers used in command sending. Client's command reply
3554 function handling now supports the mandatory command identifiers.
3556 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3557 funtions in client to fully support pending command callbacks.
3559 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3560 as one of the arguments to the application in the command reply
3563 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3564 before first releasing SILC but came back. Now it is removed again
3565 and should come back nomore. The FORWARDED flag was used only
3566 by the JOINing procedure by forwarding the command packet to router.
3567 Now, the JOINing procedure has been changed to more generic (due
3568 to various router environment issues) and FORWARDED is not needed
3569 anymore for anything. The protocol specification is yet to be
3572 Now, removed silc_server_packet_forward from server and the flag
3573 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3575 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Renamed NAMES command to USERS command. The NAMES was named that
3578 due to historical reasons. Now it is renamed. Also, rewrote
3579 parts of the USERS command. The nickname list is not sent anymore
3580 by the server. Only Client ID and mode lists are sent in the USERS
3581 command. Changed this also to the protocol specification.
3583 The client now resolves the names and stuff after it receives
3584 the USERS list from the server when joining to the channel.
3586 * WHOIS and IDENTIFY commands has been changed to support multiple
3587 Client ID's per command. One can now search for multiple users
3588 in the network by sending only one WHOIS or IDENTIFY command.
3589 Changed the code and the protocol specifications.
3591 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3592 uses silc_server_command_whois_parse to parse the request. */
3594 * If normal server, do not parse the WHOIS and IDENTIFY requests
3595 before sending it to the router. Saves some time.
3597 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Fixed JOIN command on client library. Wrong number of arguments
3600 used to crash the client.
3602 * Added silc_server_channel_has_global function to check whether
3603 channel has global users or not.
3605 * Added silc_server_channel_has_local function to check whether channel
3606 has locally connected clients on the channel.
3608 * The silc_server_remove_from_one_channel now checks whether the
3609 channel has global users or not after given client was removed from
3610 the channel. It also checks whether the channel has local clients
3611 on the channel anymore. If it does not have then the channel entry
3612 is removed as it is not needed anymore.
3614 * The silc_server_notify now checks on JOIN notify whether the joining
3615 client is one of locally connected or global. If it is global then
3616 the channel has now global users on the channel and that is marked
3617 to the channel entry. Also, it now saves the global client to
3618 global list who is joining and JOINs it to the channel. This is
3619 for normal server, that is.
3621 Changed silc_server_send_notify_on_channel,
3622 silc_server_packet_relay_to_channel and
3623 silc_server_packet_send_to_channel check if we are normal server
3624 and client has router set (ie. global client) do not send the
3625 message to that client, as it is already routed to our router.
3627 * Implemented LEAVE notify type handling in silc_server_notify
3630 * Tested LEAVE command in router environment successfully. Tested
3631 with two routers, two servers and two clients.
3635 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3637 * Implemented SIGNOFF notify type handling in silc_server_notify
3640 * silc_server_remove_id now removes the client entry from all channels
3641 it has joined and thusly sends SIGNOFF notify type.
3643 * Rewrote the NAMES list generation in server by removing two excess
3644 loops. The lists are created now inside one loop.
3646 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * silc_server_remove_channel_user checks now also global list
3649 for channel and client.
3651 * silc_server_new_channel_user checks now both local and global
3652 list for channel and client. Fixed a bug in client id decoding.
3653 Used to decode wrong buffer.
3655 * silc_server_channel_message checks now both local and global
3656 list for channel entry.
3658 * Tested channel joining (hence JOIN) in router environment
3659 successfully. Tested with two routers, two servers and two
3662 * Tested channel message sending in router environment successfully.
3664 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Added silc_server_save_channel_key into server.[ch] to save the
3667 received channel key in Channel Key payload processing. It is
3668 also used in JOIN command reply handling.
3670 Equivalent function silc_client_save_channel_key added into
3671 client.[ch] into client library.
3673 * Changed JOIN command reply to send information whether the channel
3674 was created or not (is existing already) and the channel key
3675 payload. Changed protocol specs accordingly.
3677 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3678 the request was sent by ID and not by nickname. Crashed on
3681 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3684 now correctly save the received data.
3686 * silc_server_free_sock_user_data now notifies routers in the
3687 network about entities leaving the network.
3689 At the same time implemented functions silc_server_remove_id
3690 and silc_server_send_remove_id to receive and send REMOVE_ID
3691 packets. The packet is used to notify routers in the network
3692 about leaving entities. The ID removed will become invalid in
3695 * Added function silc_idlist_del_server into server. Removes and
3696 free's server entry from ID list.
3698 * silc_server_private_message function now checks, if we are router,
3699 that the destination ID really is valid ID, naturally.
3701 * In router when NEW_ID packet is received (for new client) the
3702 hash of the Client ID is saved in the ID Cache but the
3703 client->nickname is set to NULL, instead of putting the hash
3706 IDENTIFY command now also checks that client->nickname must be
3707 valid. If it is not if will request the data from the server who
3708 owns the client. Added new function
3709 silc_server_command_identify_check.
3711 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3712 to set the command to already allocated Command Payload.
3714 * Tested private message sending in router environment with two
3715 routers, two servers and two clients. Fixed minor bugs and now
3718 * Fixed segfault from client's NAMES command. Used to crash if
3721 * Forwarded packets must not be routed even if it is not destined
3722 to the receiver. Changed server code comply with this.
3724 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added `require_reverse_mapping' boolean value to ServerParams
3727 structure. If TRUE (not default) the server will require that
3728 the connecting host has fully qualified domain name.
3730 If the reverse mapping is not required and hostname could not be
3731 found the IP address is used as hostname.
3733 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Implemented version string checking to both client and server.
3736 The check is incomplete currently due to the abnormal version
3737 strings used in development version of SILC.
3739 * Changed all command functions in server to use the new
3742 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Changed char *data to unsigned char *data in ID Cache system to
3745 support binary data as ID Cache data. Changed code to support
3746 binary data in lib/silccore/idcache.c.
3748 * Renamed silc_server_packet_relay_command_reply to
3749 silc_server_command_reply as it is normal packet receiving
3750 function. Rewrote the function to accept command replys for
3751 servers and not only for clients.
3753 * Mark remote router always as registered server if we are connecting
3754 to it. Otherwise, commands sent by the router to us are ignored.
3756 * All ID List find routines now returns the ID Cache Entry pointer
3757 as well if requested.
3759 * WHOIS command works now in router environment, tested with two
3760 routers, two servers and two clients.
3762 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3763 in router environment (as it is almost equivalent to WHOIS) but
3764 hasn't been tested thoroughly. Added new functions:
3766 silc_server_command_identify_parse
3767 silc_server_command_identify_send_reply
3768 silc_server_command_identify_from_client
3769 silc_server_command_identify_from_server
3771 * Disabled route cache adding because adding two different ID's with
3772 same IP replaces the old cache entry thus giving wrong route.
3773 The entry->router->connection is always the fastest route anyway
3774 so route cache may not be needed. Of course, new routes maybe
3775 established after receiving the ID when the entry->router->connection
3776 might not be anymore the most optimal.
3778 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Add route cache for received ID for fast routing.
3782 * Added silc_server_packet_route to route received packet on router
3783 that is not destined to us.
3785 * Renamed silc_server_get_route to silc_server_route_get.
3787 * Added id_string and id_string_len fields into SilcServer to
3788 include encoded ServerID for fast comparing without excess
3789 encoding of the ID's.
3791 * Cleaned up WHOIS command on server side. Added following static
3794 silc_server_command_whois_parse
3795 silc_server_command_whois_check
3796 silc_server_command_whois_send_reply
3797 silc_server_command_whois_from_client
3798 silc_server_command_whois_from_server
3800 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3801 arguments in command replies. All command functions should be
3802 updated to use this macro.
3804 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Minor typo fixes on command reply handling on server.
3808 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Added silc_server_command_add_to_channel internal routine to add
3811 the client to the channel after router has created the channel and
3812 sent command reply to the server.
3814 * Added generic silc_server_send_command to send any command from
3817 * Use static buffer with ID rendering instead of duplicating data.
3819 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Fixed a channel user mode bug when joining to a channel server gave
3822 everybody channel founder rights, oops.
3824 * We mark ourselves as the router of the incoming server connection
3825 if we are router ourselves. This way we can check in some packet
3826 sending functions whether it is locally connected server. For
3827 incoming router connections we put NULL.
3829 * For router sending packets locally means now always sending the
3830 packet cell wide; to local clients and local servers. For normal
3831 server sending packet locally means sending it to only local
3834 * Fixed the JOIN command to really work in router environment. If the
3835 channel is created it is always created by the router. Router is
3836 also responsible of making the initial joining to the channel,
3837 sending JOIN notify to the sending server and distributing
3838 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3839 does not exist server doesn't do anything else but forward the
3840 command to the router which performs everything.
3842 * Added silc_server_send_channel_key function to send the Channel Key
3845 * Added silc_server_create_channel_key to create new channel key. The
3846 channel key is now re-generated everytime someone joins or leaves
3847 a channel, as protocol dictates. Note: channel->key_len is the
3850 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3853 packet_receive.[ch] to separate packet sending and receiving
3854 routines. The server.[ch] now includes everything else including
3855 actual packet processing (writing and reading data) and other
3858 Renamed silc_server_private_message_send_internal to
3859 silc_server_send_private_message. The routine is still though
3860 used only to relay private messages as server does not send
3861 private messages itself.
3863 Renamed silc_server_new_channel to silc_server_create_new_channel
3864 and added new function sicl_server_new_channel that handles the
3865 incoming New Channel packet. Added also new sending function
3866 silc_server_send_new_channel to send New Channel Payload.
3868 * Added new function silc_server_notify to process incoming notify
3869 packet to the server/router. Server may then relay the notify
3870 to clients if needed.
3872 * Added new function silc_server_new_channel_user to process incoming
3873 New Channel User packet. Router will redistribute the packet and
3874 send JOIN notify to its local clients and locally connected servers
3875 if needed. Normal server will send JOIN notify to its local client
3876 on same channel when received this packet. Added also corresponding
3877 sending function silc_server_send_new_channel_user to sent the
3880 * Added boolean route argument to send_notif_to_channel and
3881 packet_send_to_channel functions to attempt to route the packet
3882 if it is TRUE and send only locally if it is FALSE.
3884 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * silc_server_replace_id now broadcasts the received replace ID
3887 packet if it is not broadcast packet already. The router must
3888 broadcast to inform other routers about changed ID.
3890 * Added backpointer to server's router into SilcServer context in
3891 silcd/server_internal.h.
3893 * Fixed silc_server_packet_broadcast to send correct broadcast
3896 * The channel key is now distributed to the local client as soon
3897 as it is received from the router (in router environment) so that
3898 no other packet may be sent for the channel until client has
3901 * silc_server_remove_channel_user now broadcasts the received
3902 Remove Channel User packet if it is not broadcast packet already.
3903 The router must broadcast to inform other routers about removed
3906 * Added users field into SilcPacketContext that is a reference count
3907 of the context. One can increase the reference count by calling
3908 silc_packet_context_dup which is now changed to just increase the
3909 reference count instead of duplicating the data. The reference
3910 count is decresed by calling silc_packet_context_free that will
3911 free the data after the reference count hits zero.
3913 For now on the packet context and everything allocated into it
3914 (including the raw packet from network) must be freed by calling
3915 the new silc_packet_context_free function. Added also new function
3916 silc_packet_context_alloc that must be used now to allocate the
3917 context. This also means that if a routine is asynchronous from
3918 silc_[client/server]_packet_parse_type the packet context must
3919 be duplicated by calling silc_packet_context_dup. Otherwise it
3920 gets free'd after silc_[client/server]_packet_parse_type returns.
3921 Also, one must remember that if packet is duplicated then its
3922 reference count must be decresed by calling the free function as
3923 many times as it was duplicated.
3925 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3926 from both client and server.
3928 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Made joining to a channel working in router environment.
3932 * Cleaned up JOIN command on server side and create function
3933 silc_server_command_join_channel internal routine to make the
3936 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Changed silc_command_pending list to SilcDList. Also, added
3939 `ident' field to SilcServerCommandPending structure to identify
3940 the reply and to call correct callback.
3942 Added silc_server_command_pending_check function to replace the
3943 corresnponding macro. The silc_command_pending list is not
3946 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3947 to set identifier to previously allocated Command Payload. It
3948 is used to set identifier for command when resending Command
3951 * Added silc_command_payload_encode_payload to encode Command
3952 Payload buffer from SilcCommandPayload structure.
3954 * Added silc_argument_payload_encode_payload to encode Argument
3955 payload buffer from SilcArgumentPayload structure.
3957 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Changed WHOIS command to support router connection on server side.
3960 The whois request is always sent to router unless the server is
3961 standalone server. After server has received the reply from the
3962 router will it send the reply to the client.
3964 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3965 broadcast received broadcast packet. The function is used only
3966 by router. The broadcast packet is always sent to the router's
3969 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3970 render given ID to printable string, for log files for example.
3972 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Made basic router to router connections working. At least they
3975 can now connect to each other but nothing really works the way
3976 they are supposed - yet.
3978 * Added new initiator token to RouterConnection configuration
3979 file in silcd/serverconfig.[ch]. It is used to tell whether we
3980 are the initiator to the remote router or whether we'll expect
3981 the other end to connect.
3983 * Moved registering of listener task to silc_server_init, hence
3984 the server starts listenning as soon as it is run, even if it
3985 does not have connections to other routers. Let's see how well
3988 * Changed default connection retry timeouts for more suitable in
3991 * Removed cipher and such arguments from silc_idlist_add_client
3992 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3993 Added new function silc_idlist_add_data to add the keys and stuff
3996 * Added SilcIDListData structure and added it to SilcClientEntry
3997 and SilcServerEntry as their first field in the structure. This
3998 way we can explicitly cast the ID entries to the SilcIDListData
3999 structure and get common data for the entries. In past, we had
4000 to first check what type of connection it is and then cast it to
4001 correct ID entry type. Now, we can directly cast the opaque
4002 pointer to the SilcIDListData (no matter what ID entry it actually
4003 is) and get the data needed.
4005 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4008 in some circumstances even if threre were timeout tasks, though not
4009 IO tasks, but tasks anyway. Now fixed.
4011 * Defined SilcServerConnection structure to hold connection specific
4012 stuff about directly connected servers and routers. The definition
4013 is currently in silcd/server_internal.h. I thought about having
4014 a bit more important role fro this struct but for now it is used
4015 only when connecting to other server (or router actually).
4017 * Added connecting retry support in server when connecting to
4018 router(s). The retry feature implement exponential backoff
4019 algorithm. Also, added SilcServerParams structure to hold default
4020 parameters for server. For now, it include these retry settings
4021 and are hard coded. After server is moded to be as Silc Server
4022 Library this structure will be more important.
4024 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Changed client librarys channel->clients table to SilcList and
4027 changed code accordingly.
4029 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Changed client's channel table to SilcList and changed code
4032 accordingly. Also changed SilcChannelClientEntry to include back-
4033 pointer to the channel so that client entry can use that structure
4034 as list as well and we have fast cross-reference to the channel.
4035 This change dramatically decreased the complexity of channel
4036 handling with client entry and vice versa (removed one extra
4037 loop when searching for channel entry from many functions).
4039 * Changed server->sim from table to SilcDList and changed code
4042 * NAMES command can now be used from user interface. It will show
4043 the user list on the channel, neatly.
4045 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4046 Code now saves realname of the user if it becomes available.
4048 * Renamed configure.in to configure.in.pre and made ./prepare
4049 script to automatically add correct version string to
4050 configure.in which it creates from configure.in.pre.
4052 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * NAMES command reply now shows users mode with the nickname when
4057 * Moved silc_client_ch[u]mode[_char] functions from
4058 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4059 place sucks, they are utility functions and should be in some
4062 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4064 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4067 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Added TRQ (efficient deque and list library) into lib/trq. This is
4072 a very good list library that is currently used in the SILC. Defined
4073 SilcList API over the library because I didn't like the API very
4074 much. See lib/trq/silclist.h for the API and examples of how to
4075 use the API. Fixed various places in the code to use the new
4076 SilcList API. The SilcList is meant for lists that has a structure
4077 already defined as a list. It is not suitable to add just some
4078 context to the list (in TRQ, the context is the list actually).
4080 So, I defined SilcDList that can be used for the purpose where
4081 predefined list structure does not exit. This can be used as
4082 such list. Now some context just can be added to the SilcDList.
4083 Currently this list is not used in the SILC just yet, though there
4084 are a lot places where this can replace dynamically allocated
4085 tables and I will fix these places, later, to use SilcDList.
4086 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4087 and use TRQ internally).
4089 Also fixed some annoying warning messages that the original TRQ
4090 code generated. Also minor changes to TRQ's Makefile.in.
4092 * Added support for querying by Client ID to both WHOIS and
4093 IDENTIFY commands into server, as required by the protocol.
4095 * Removed method function pointers from SilcBuffer structure. They
4096 weren't used to anything and just increased the context size for
4097 no good reason. This change also made silc_buffer_alloc and
4098 silc_buffer_free functions inline functions.
4100 * Disabled command flooding detection support until it's fixed so
4101 that it accepts commands in but does not execute them more than once
4104 * Added silc_net_localhost(), to return local hostname, into
4105 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4106 that must be initialized before calling silc_client_init.
4108 * Added new function: silc_server_send_notify_on_channels to send
4109 notify messages to all channels client has joined. It is assured
4110 that the message is sent only once per client.
4112 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4113 lib/silcutil/silcutil.[ch] as silc_format function. The new
4114 function is generic and is used by server as well, not only by
4115 the logging routines.
4117 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4118 the provided version string was not acceptable. Added new function:
4119 silc_ske_check_version into lib/silcske/silcske.h. The function
4120 must be implemented by the application (client or server) and it
4121 does not reside in the SKE library. The function checks the version
4122 string remote end sent.
4124 * Added back pointers (to opaque context and to SilcSocketConnection)
4125 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4127 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4128 duplicate packet context structure.
4130 * Changed `notify' client operation to send same arguments as client
4131 receives from server except for ID's. ID's are mapped to correct
4132 ID entry and that is returned. Also, if channel entry is not sent
4133 by server but the notify is for channel the channel entry is sent
4134 to application (otherwise application doesn't know that it is for
4135 channel (library gets it from packet's Destination ID)).
4137 * Added silc_client_remove_from_channels into client library to
4138 remove a client from all channels it has joined to. Used when
4139 received SIGNOFF notify from server. Added also new function
4140 silc_client_replace_from_channels to replace old ID entry with
4141 new ID entry on all channels. Used when received NICK_CHANGE
4144 * Fixed ID Cache list handling in silc_idlist_get_client in
4145 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4146 to get (or query) client by ID.
4148 * Updated TODO list.
4150 * Added connection authentication status message defined by the
4151 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4152 support for these into the code in client and server side.
4154 * Added generic function silc_client_send_command to send any command
4155 with variable argument list. Application should use this function
4156 to send commands if the command functions provided by the library
4157 does not suite for the application's user interface needs.
4159 * Added new `failure' client operation. Application is notified about
4160 received failure packet if client is executing a protocol. In this
4161 case the protocol's execution has failed.
4163 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4164 is required by the protocol.
4166 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4167 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4170 * Added status flag to SilcSKE object to indicate realtime status
4171 of the SKE protocol.
4173 * Application receives now exactly same command reply arguments as
4174 the library receives from server. However, if ID is received the
4175 corresponding ID entry is returned to the application (eg. Client
4176 ID is mapped to correct SilcClientEntry entry and that is returned).
4177 Changed command_reply client operation due to this change.
4179 * Changed all ID's in commands and in command replys as ID Payloads.
4180 Change affected both client and server side codes.
4182 All ID's sent in SILC network (with execption of ID's in SILC
4183 Packet header) are sent in ID Payload to support variable length
4186 * Server now notifies nick changes and notifies all clients on
4187 the channels about the new nickname (about the new Client ID,
4190 * Implemented CMODE command to change channel modes. Supports all
4191 channel modes defined by the protocol specs except ban and invite
4192 lists. (Also, private channel key mode is supported but support for
4193 setting private channel key in client is missing, thus, this mode
4194 has no effect on client side (except that server requires that the
4195 client uses private channel key and normal channel traffic does not
4198 Also, invite mode works per se, but INVITE command does not work
4199 yet correctly, so you can set channel as invite only channel but
4200 inviting clients to the channel does not work (it is yet to be
4201 thought what's the best way to do it).
4203 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4204 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4205 Implemented CUMODE command to change user's mode on the channel.
4206 Supports all modes defined by the protocol specs.
4208 * Added NAMES command reply to return users modes on the channel.
4210 * Removed unnecessary and slow ciphers from lib/silccrypt.
4212 * Set SO_KEEPALIVE option to connection sockets by default.
4214 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4216 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4217 redefined the Notify Payload into protocol specs.
4219 * Added silc_id_payload_parse_id to get ID directly from raw
4222 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4225 accept searching by Client ID as well.
4227 * Added support for LEAVE and SIGNOFF notify types in client library.
4229 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4230 to parse ID Payload from raw data.
4232 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Added flags parameter into silc_ske_assemble_security_properties
4235 function in lib/silcske/silcske.[ch].
4237 * Changed notify client operation to fit better for notify messages
4238 sent by server. The notify payload received from server is now
4239 passed to the application (after parsing it to SilcNotifyPayload).
4240 It is application's responsibility to retrieve the arguments
4241 from the payload and show the message the way it wants. The message
4242 sent by server is implementation specific.
4244 * Changed public keys to comply with the protocol specification.
4245 Old public keys are not supported anymore and are not compatible.
4247 * Removed nickname from Channel Payload as the latest draft removed
4248 it. The client must resolve the nickname from the NAMES command
4249 reply received when it joined the channel.
4251 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4253 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Fixed some errors in protocol specification drafts.
4257 * Created lib/silccore/silcnotify.c to implement Notify Payload
4258 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4259 generic payloads described by protocol specifications. The file
4260 includes implementations for ID Payload and Argument Payload.
4262 * Changed Command Payload implementation to use the new Argument
4263 Payload. Changed command_xxxx_payload to command_payload_xxxx
4264 to comply with SILC coding conventions.
4266 * Added suppport for Argument Payload handling in Notify Payload
4267 implementation as protocol requires it. Added the new support
4268 into server and client lib as well.
4270 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added support for multiple nicknames on same channel. [n] is
4273 added locally to the nickname if there are more than one same
4274 nicknames on the channel.
4276 * Server now sends all nicknames that matched WHOIS request.
4277 Client also shows the list received from server.
4279 * Added TOPIC command to client side. User can now set and show
4280 current topic on channel.
4282 * Added MOTD command to client and server. Also, server sends the
4283 motd when client connects to the server.
4285 * Changed version strings to comply ISO 8601.
4287 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Fixed protocol error handling in client library. It should now
4290 cope even if the SKE fails for some reason.
4292 * Made new protocol specification drafts for submitting to IETF.
4294 * Implemented TOPIC command to server in silcd/command.c.
4296 * Added two new notify types into lib/silccore/silcnotify.h:
4297 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4298 notify nickname change and topic setting/change on a channel.
4300 * API change of command_reply operation in client library. The
4301 application gets now the status type received from server as well.
4303 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4307 * Cras fixed and optimized the packet handling even further and
4308 it should work now. Minor change to the prototype of function
4309 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4311 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Added new function into lib/silcutil/silcschedule.[ch]:
4314 silc_schedule_with_fd to select() a specified fd. The function
4315 returns after timeout expires or data arrives or goes. The
4316 function is used by packet routines to wait that all data is
4317 received from network.
4319 * Fixed data reading from network in lib/silccore/silcpacket.c.
4320 The code now assures that all data is read from the fd and then
4321 continues packet processing. This was a bug fix since the code
4322 used to drop some data in some circumstances.
4324 * Added new function into lib/silcclient/client.[ch]:
4325 silc_client_start_key_exchange to start key exchange after
4326 connection has been established to server. The code internally
4327 now uses this funtion but its main purpose was to provide it
4328 for applications that perform their own connecting. After
4329 application has created a connection it merely calls this
4330 function to start the key exchange between client and server.
4331 The library takes care of everything else after that.
4333 Updated also lib/silcclient/README to explain the usage of
4336 * Do not send to application information that connection has
4337 been established. Application gets notified it by connect
4340 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Applied cras's patch to add silc_schedule_one function. The
4343 function runs scheduler once and returns.
4345 * Fixed the scheduler after cras messed it up. The timeout
4346 handling works now as it's supposed to work.
4348 * Added into lib/silccore/ silcnotify.h to include notify
4349 message types support. Changed silc_server_send_notify*
4350 functions, in server.[ch], to support those new notify types.
4351 Added the support for the notify types into client library,
4352 as well. Added new notify client operation into ops.h in
4355 * Changed silc_server_packet_send_to_channel to send normal
4356 packets instead of just channel message packets. The function
4357 is now used to send the notify packets to channels. It is not
4358 used to send channel message packets anymore, as server never
4361 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4362 va_arg()s as it seems to require it nowadays. I guess, if SILC
4363 is compiled with older va_arg() the new code should work anyway.
4365 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Splitted core library. Core library (lib/silccore) includes
4368 now only SILC protocol specific core (and common) components.
4369 Created new utility library (lib/silcutil) that includes more
4370 generic purpose stuff. The stuff for util library was taken
4371 from the old core library. This was minor and easy split.
4373 * Created SILC Client Library (lib/silcclient) that includes
4374 implementation of the SILC client without user interface. This
4375 was major move from silc/ directory. The code has been changed
4376 so that it is transparent towards the user interface. The
4377 silc/ directory includes now the same user interface as before
4378 and it uses the new client library. Read lib/silcclient/README.
4379 Basicly, the client library performs everything else related
4380 to SILC except user interface handling. Also, configuration
4381 files are considered to be part of user interface and library
4382 does not handle them.
4384 This change also changed a lot of structures, function naming etc.
4385 Most important change was that SilcClientWindow object was
4386 renamed to SilcClientConnection in the client library. Created
4387 also new file lib/silcclient/ops.h. Also added new files
4388 silc/local_command.[ch] and silc/client_ops.[ch].
4390 All these changes were made to make it easier for user interface
4391 designers to create what ever user interface for the SILC client
4394 It is also expected that the server will be moved to lib
4395 directory as well and SILC Server Library will be created;
4396 sometimes in the future.
4398 * Removed Local commands from lib/silccore/silccommand.h as
4399 they are application specific and new client library does not
4400 handle any of those anymore.
4402 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4403 old client implementation in silc/.
4405 * Added support for callback functions in SILC_LOG_* macros.
4406 Application can now set its own callbacks that will be called
4407 instead of using the default functions that will always print
4408 the debug messages to stderr (or stdout). Also, debugging can
4409 now be disabled by setting silc_debug to FALSE and re-enabled by
4410 setting it to TRUE. Note, that logging will still work even
4411 if debugging is disabled.
4413 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4414 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4415 silc_log_reset_debug_callbacks.
4417 * To enable debugging in silc client one must give now -d
4418 option on command line.
4420 * Changed silc_schedule_init to automatically allocate task queues
4421 if they are not allocated before calling it.
4423 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Added GMP 3.1 into math library.
4427 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4430 a channel in SILC network. The packet is used by servers and
4431 routers to notify other routers that user has left a channel.
4432 This little feature was missing until now. Added the feature
4433 to protocol specification as well.
4435 Added functions: silc_server_send_remove_channel_user and
4436 silc_server_remove_channel_user into server.[ch].
4438 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4439 lib/silccore/silcpacket.h. However, they are not implemented
4442 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Fixed joining to a channel and sending channel messages
4445 between server and router. The channel message sending should
4446 now work inside a cell.
4448 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Fixed the private message sending between server and router.
4451 The private message sending should now work inside a cell.
4453 * Added silc_server_replace_id into server.[ch] to replace
4454 existing ID in the SILC network.
4456 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4457 and silc_idlist_replace_server_id into idlist.[ch] in server.
4459 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Fixed the server to server connections. Server can again now
4462 connect to router. Router to router connections probably does
4465 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Added dynamic protocol registering support. Now protocols can
4468 registered and unregistered on the fly. Patch by cras.
4470 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Added lib/contrib directory to hold routines that some platforms
4473 don't have but are needed by SILC.
4475 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4476 into lin/contrib to provide getopt() and getopt_long() for
4477 those who don't have it.
4479 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Added AWAY command to client. When away message is set and
4482 client receives a private message packet the client automatically
4483 replies to the sender with the away message.
4485 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4486 bug seemed to be the cause of recent problems when compiling
4489 * Added version detection support to SKE protocol specification
4490 and added the new changes to the SKE implementation as well.
4491 There were other minor changes in the SKE protocol as well.
4493 Many changes in lib/silcske/silcske.[ch] and in
4494 lib/silcske/payload.[ch].
4496 * Added ^U functionality, clear input line. Patch from cras.
4498 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Mainly small bugfixes on core library. Fixed some debugging
4501 logging and buffer overflow in silclog.c.
4503 * Updated config.sub and config.guess on the distribution tree.
4505 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Added command lagging support in server. Client may execute
4508 commands now only once in two seconds.
4510 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Optimized packet reception. MAC computation and checking is now
4513 also more optimized. A lot previously duplicated code is now
4514 used as generic by both client and server.
4516 * Fixed key pair generation in clientutil.c
4518 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Added into lib/silccore/silcbufutil.[ch] new function;
4521 silc_buffer_realloc.
4523 * Moved generic packet sending/encryption functions to
4524 lib/silccore/silcpacket.[ch] from client and server. Some
4525 rewriting of the functions.
4527 * Moved all generic packet reception/decryption functions to
4528 lib/silccore/silcpacket.[ch] from client and server. The
4529 packet processing is now much cleaner in both client and server.
4530 These were major changes in both client and server.
4532 * Created many common functions in server to do packet sending.
4533 Previously code were duplicated a lot, this has been removed
4536 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Rewrote major parts of the ID cache system. Don't know
4539 whether it is better now or not but at least the API is more
4542 * Major rewrite on ID cache stuff on client because of the ID
4543 cache API changes. Added idlist.c to client.
4545 * Also major rewrite on ID cache stuff on server as well.
4546 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4547 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4548 in hand, instead they are all put into the ID cache system now.
4549 All server_idlist_* routines uses ID cache now instead of
4550 traversing its own lists (those lists does not exist anymore).
4551 SilcIDList though still exists. Also, SilcXXXEntry's are
4554 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Finally made the SKE implementation compliant to the protocol
4557 specification. All mp integers are now binary encoded as
4558 opposed being HEX encoded.
4560 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4563 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4564 functions: silc_[encode/decode]_pem. Also added function
4565 silc_encode_pem_file to PEM encode with newlines ('\n') for
4568 * SILC public keys are now encoded either PEM or binary. Same
4569 option is for private keys as well. By default private keys
4570 are binary encoded and public keys PEM encoded. Silly HEX
4571 encoding were removed.
4573 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4574 function to create fingerprints.
4576 * Fixed a bug in SHA1; does not change the original data anymore.
4578 * Partly implemented INFO command on client and server side.
4579 Fixed CLEAR command. Changes to SERVER command; show current
4580 server(s) when giving command without arguments. Added
4581 VERSION command to client.
4583 * Added check to server that unregistered connections cannot
4584 execute commands (unless it is specificly allowed).
4586 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Fixed screen refresh.
4590 * Fixed channel joining bug from client. On some circumstances
4591 client tried to join to a channel it had already joined.
4593 * Added public key verification process into client's protocol.c.
4594 The client now verifies the public key from user and saves
4595 it into ~./silc/serverkeys/ directory.
4597 Added into: clientutil.[ch]: silc_client_verify_server_key.
4599 * Changed SKE protocol's silc_ske_initiator_finish function
4600 to accept callback function that verifies the received public
4601 key. Removed old silc_ske_verify_public_key function.
4603 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4606 silc_pkcs_private_key[_data]_set.
4608 * Made the password and public authentication more cleaner in
4609 server's protocol.c.
4611 * Removed historic and obsolete protocol `channel_auth' from
4612 both client and server.
4614 * Removed wrong way of sending command status messages from
4615 server to client in server's command.c. The old way violated
4616 protocol specification.
4618 Changes to silccore/silccommand.[ch]: removed
4619 silc_command_encode_status_payload -> not needed anymore,
4620 changed silc_command_encode_payload_va to accept extra
4621 argument on variable argument list. The argument type must
4622 now be provided to the function. Also, added new function:
4623 silc_command_encode_reply_payload_va which is same as
4624 normal command_encode_payload_va except command status type
4625 is provided as extra argument.
4627 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Added ~./silc directory handling. The directory includes the
4630 public and private keys for the client.
4632 Added silc_client_check_silc_dir, silc_client_create_identifier
4633 and silc_client_load_keys.
4635 * Implemented SILC protocol compliant public key. Added public
4636 and private key saving to and loading from files.
4638 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4639 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4640 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4641 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4642 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4644 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4645 silc_pkcs_load_[public/private]_key.
4647 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Added silc_server_get_route (route.[ch]) to get connection
4650 data for the fastest route for given ID.
4652 * Implemented INVITE command on client and server. The command
4653 were re-defined in the SILC Protocol Specification and the
4654 implementation now complies with the specification.
4656 * Implemented PING command on client and server.
4658 * Implemented NAMES command on client and server. The server side
4659 supports currently only normal server not router server yet.
4660 Some changes to NAMES definition in SILC protocol specification.
4662 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Implemented LEAVE command on client and server.
4666 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4667 again. This change was made to the protocol as well. Server
4668 should not violate the protocol specification anymore.
4670 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4673 was tested. SOCKS4 was not but should work anyway.
