1 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed MSVC++ project files and added missing files to
4 Makefiles under win32/.
6 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
8 * Do not add TCP_NODELAY flag if the operating system
9 does not have it defined. Affected files are
10 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
12 * Fixed buffer overflow from Irssi SILC Client. Affected
13 file irssi/src/fe-common/core/themes.c.
15 * Fixed double free in client library in the file
16 lib/silcclient/client.c when disconnecting from server.
18 * Applied double free patch from cras to Irssi SILC client.
19 Affected files irssi/src/core/[modules/expandos].c
21 * Fixed the disconnection handling to Irssi SILC Client.
22 The application must call silc_client_close_connection
23 in ops->connect client operation in case of failure of
24 the connection. Affected file is
25 irssi/src/silc/core/client_ops.c.
27 * Do not set sock->protocol to NULL in the function
28 silc_client_close_connection after executing the protocol's
29 final callback since the sock might not be valid anymore.
30 Affected file lib/silcclient/client.c.
32 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
34 * Do not enable SILC_THREADS if the linking with libpthread
35 did not happen. Affected file configure.in.pre.
37 * Added notion to protocol specification that server must
38 verify the sent authentication payload with CMODE when
39 setting the channel founder key. Implemented it to the
40 server. Affected file silcd/command.c.
42 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
44 * Added _EXTRA_DIST SILC distribution variable to the
45 distributions file. It is used to conditionally add extra
46 files or directories to the specific distribution. Affected
47 files ./prepare, Makefile.am.pre and distributions.
49 Removed the `_' from the start of the distribution names.

55 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Fixed a double free in disconnection in the server. Affected
58 file is silcd/server.c.
60 * Fixed the lib/silcske/groups.c to work now also with GMP
61 MP library. The string conversion did not work when using
62 specific base and the base is indicated in the string as well.
64 * Created win32/ directory which now includes MSVC++ specific
65 stuff so that toolkit (DLLs) may be compiled with MSVC++.
66 It will appear only in the toolkit distribution
68 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
70 * Changed the key material distribution function in case when
71 the hash output is too short. The data is now concatenated
72 a bit differently than it used to. Made the change to the
73 SKE protocol specification.
75 * Added better GMP detection to configure.in.pre. A patch
78 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
80 * Fixed a minor bug in SKE that might cause some problem on
81 some platforms. Affected file lib/silcske/silcske.c.
83 * Added the cookie checking for initiator in the SKE. It checks
84 that the responder returns the sent cookie unmodified. The
85 affected file is lib/silcske/silcske.c. Added new SKE
86 error type INVALID_COOKIE that can be sent during the
87 negotiation. Fixed some memory leaks as well.
89 * Added the "invalid cookie" error message to Irssi SILC client's
92 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
94 * Added `task_max' field to the SilcClientParams to indicate
95 the maximum tasks the scheduler can handle. If set to zero,
96 default values are used. Affected file lib/silcclient/silcapi.h.
98 * Fixed memory leaks in silc_client_close_connection. Affected
99 file lib/silcclient/client.c.
101 * Added silc_client_del_client_entry to client library to free
102 all memory of given client entry. Affected file is
103 lib/silcclient/idlist.[ch].
105 * Added new functions silc_client_del_channel and
106 silc_client_del_server to delete channel and server entries.
107 Affected file lib/silcclient/[silcapi.h/idlist.c].
109 * Removed silc_client_del_client_by_id from silcapi.h.
111 * Fixed the INFO command to return the server's own info
112 correctly when querying by Server ID. Affected file is
115 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
117 * Removed the non-blocking settings in WIN32 code in the
118 silc_sock_[read/write] and added SleepEx instead. Affected
119 file lib/silcutil/win32/silcwin32sockconn.c. The availability
120 of input data is now checked with FIONREAD and ioctlsocket.
122 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
124 * Call silc_schedule_task_del_by_context in the
125 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
126 Affected file lib/silccore/silcprotocol.c.
128 * Call silc_protocol_cancel for active protocols in the
129 silc_server_close_connection if the funtion
130 silc_server_free_sock_user_data has not been called.
131 Affected file silcd/server.c.
133 * Generic tasks cannot be deleted using the del_by_fd
134 task deleting function since generic tasks does not match
135 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
137 * Added a notion to SILCOPER help file that the SILCOPER works
138 only on router server, not on normal server.
140 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
142 * Added for WIN32 support for the new scheduler as well.
143 Affected file lib/silcutil/win32/silcwin32schedule.c.
145 * Fixed the SHA1 implementation to work on various platforms.
147 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
149 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
150 API. It is part of the scheduler now. Everything else is
151 as previously but some functions has changed their names.
152 Checkout the lib/silcutil/silcschedule.h for the interface.
153 Updated all applications to use the new interface. Affected
154 files are lib/silcutil/silcschedule.[ch].
156 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
158 * Found a bug in the SKE implementation. The HASH value,
159 specified by the protocol, was not computed correctly. The
160 public key of the responder was not added to the computation
161 even though it is mandatory. Affected file lib/silcske/silcske.c.
162 This unfortunately causes incompatibilities with older
165 * Added WIN32 specific network init and uninit functions:
166 silc_net_win32_init and silc_net_win32_uninit to init and uninit
167 the Winsock2. Affected file lib/silcutil/silcnet.h and
168 lib/silcutil/win32/silcwin32net.c.
170 * Set the socket always to nonblocking mode on WIN32 after
171 reading data or writing data. Affected file is
172 lib/silcutil/win32/silcwin32sockconn.c.
174 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
176 * Fixed various compilation problems under WIN32. Affected
177 files lib/silcutil/win32/silcwin32thread.c and
178 lib/silcutil/win32/silcwin32schedule.c.
180 * Removed all _internal.h #includes from public header
181 files. Internal headers must never be included from
184 Removed also the lib/silcske/payload_internal.h file.
186 * All include files that may be needed (public and some others
187 included by the public headers) by application developers are
188 now copied to the ./includes directory. It does not copy any
189 internal headers. Affected file Makefile.defines.pre and all
190 Makefile.am's under lib/ and subdirs.
192 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
194 * Do not change the ~/.silc directory's permissions automatically.
195 Affected file irssi/src/silc/core/clientutil.c.
197 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
199 * Do not cancel the protocol in silc_server_close_connection
200 it might cause recursion. Now cancelled in the function
201 silc_server_free_sock_user_data. Affected file silcd/server.c.
203 * Fixed the silc_server_remove_clients_by_server to regenerate
204 the channel keys correctly finally. Added also new function
205 silc_server_remove_clients_channels to actually do it.
206 Affected file silcd/server.c.
208 * Fixed the silc_server_new_channel to not crash by giving
209 wrong router to the new channel. Affected file is
210 silcd/packet_receive.c.
212 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
214 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
215 which is given as argument to the silc_client_alloc now.
216 It can be used to configure the client and set various parameters
217 that affect the function of the client.
219 * The USERS command in server did not check whether the channel
220 is private or secret. Affected file silcd/command.c.
222 * Added new argument to the USERS command in protocol specification.
223 The USERS command now can take the channel name as argument
224 as well. Added support for this in client and server and
225 updated the protocol specs.
227 * Completed the GETKEY command in client. It can be now used
228 to fetch also servers public key not only some clients.
229 Affected files lib/silcclient/command[_reply].c.
231 * Added silc_client_get_server to return server entry by the
232 server name. Affected files lib/silcclient/silcapi.h and
235 * Redefined the IDENTIFY command in protocol specification to be
236 more generic. It now can be used to query information about
237 any entity in the SILC Network, including clients, servers and
238 channels. The query may be based either the entity's name
239 or the ID. Added support for this in both client and server.
241 Affected files silcd/command.c and lib/silcclient/command.c
244 * Optimized the WHOIS and WHOWAS commands in the server. Removed
245 the _from_client and _from_server functions. Affected file
248 * Added silc_client_get_channel_by_id_resolve to the file
249 lib/silcclient/silcapi.h to resolve channel information by
250 its ID. Added also silc_client_get_channel_by_id that
251 does not resolve it from the server.
253 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
255 * Added SilcServerEntry context into the client library
256 to represent one server. The INFO command now allocates
257 these to save the resolved server info. For now on the
258 client library will also keep information about servers,
259 connected and resolved with INFO.
261 The INFO command now allocates the SilcServerEntry context
262 and saves the server info there. The COMMAND_REPLY in
263 the INFO now returns the parameters to application in
264 same order as defined in the protocol specification.
266 The entries are cached in the client->server_cache.
268 * The INFO command is now issued after received the Client ID
269 from the server. Affected file lib/silcclient/client.c.
271 * The CMODE_CHANGE notify may now return also an SilcServerEntry
272 to the application as the mode changer might be server.
273 It is guaranteed that NULL is not returned anymore to the
274 application. Affected file lib/silcclient/client_notify.c.
276 The ID Type is now also passed to the application so that
277 it can check whether the returned entry is SilcClientEntry
280 Added new function silc_client_get_server_by_id to return
281 the server entry by ID. Affected files are the
282 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
284 * Do not create the channel in the Irssi SILC Client when issuing
285 the JOIN command but when received the sucessful JOIN command
286 reply. Otherwise the channel might get created even though we
287 could not join it. The Affected file is
288 irssi/src/silc/core/[silc-channels.c/client_ops.c].
290 * Fixed a channel joining bug in router. The router must also
291 check the channel modes, invite and ban lists etc. when serving
292 the JOIN command sent by normal server. Affected file is
293 silcd/command.c. The router now resolves the client's
294 information from the server who sent the JOIN command if it
295 does not know it, and processes the JOIN command only after
298 * Changed the SilcCommandCb to take new argument; void *context2.
299 Affected file lib/silccore/silccommand.h
301 The second argument in the command callbacks in the server now
302 includes the SilcServerCommandReplyContext if the command was
303 called as pending command callback from the command reply.
304 Otherwise it is NULL. When called as pending the status of the
305 command reply will be checked and if it was erronous the
306 error will be sent to the original sender of the command.
307 This way the client always receives the error messages even
308 though the server was actually the one who received the error
309 when it resent the command to router, for example. Affected
310 files silcd/command[_reply].[ch].
312 * Fixed sending WHOWAS command's error message to client if
313 the requested client could not be found. It was missing.
316 * Changed the CMODE and CUMODE commands reply arguments in the
317 protocol specification. The Channel ID is now sent in both
318 of the commands to identify the channel. Implemented this
319 new feature to the client and server. Affected files
320 lib/silcclient/command_reply.c and silcd/command.c.
322 * Made better checks for invite and ban lists in the JOIN
323 command in server. Affected file silcd/command.c.
325 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
327 * The server now performs the incoming host IP/DNS lookup
328 using the silc_socket_host_lookup and thus does not block
329 the server anymore. Affected file silcd/server.c.
331 * Completed the multi-thread support for SILC Scheduler in
332 the lib/silcutil/silcschedule.c.
334 * Fixed the configure.in.pre to detect the pthread correctly
337 * Fixed a deadlock in silc_task_queue_wakeup in the file
338 lib/silcutil/silctask.c.
340 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
342 * Added new function silc_schedule_wakeup that is used in
343 multi-threaded environment to wakeup the main thread's
344 schduler. It needs to be used when a thread adds a new task
345 or removes a task from task queues. After waking up, the
346 scheduler will detect the task queue changes. If threads
347 support is not compiled in this function has no effect.
348 Implemented the wakeup mechanism to both Unix and WIN32
349 systems. Affected files are lib/silcutil/silcschedule.[ch],
350 lib/silcutil/unix/silcunixschedule.c and the
351 lib/silcutil/win32/silcwin32schedule.c.
353 * Added new function silc_task_queue_wakeup to wakeup the
354 scheduler by the specified task queue. Affected file
355 lib/silcutil/silctask.[ch].
357 * The silc_socket_host_lookup_start now wakes up the scheduler
358 after adding the timeout task. Affected file is
359 lib/silcutil/silcsockconn.c.
361 * The silc_socket_host_lookup is synchronous now if the threads
362 support is not compiled in. However, the callback is still
363 called asyncronously through the scheduler, anyway. Affected
364 file lib/silcutil/silcsockconn.c.
366 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
368 * Added new function silc_socket_host_lookup to perform
369 asynchronous IP and FQDN lookups for the socket connection.
370 Affected files lib/silcutil/silcsockconn.[ch].
372 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
374 * Added SILC_MUTEX_DEFINE to define the mutex on environments
375 that may or may not compile the mutex support in.
377 Changed the silc_mutex_alloc interface. It allocates the
378 mutex now to the sent pointer and returns TRUE or FALSE.
380 Affected file lib/silcutil/silcmutex.h.
382 * Wrote the SILC Task Queue interface to support multi-threads.
383 Affected file lib/silcutil/silctask.[ch].
385 * Wrote the SILC Scheduler to support multi-threads. Affected
386 file lib/silcutil/silcschedule.c.
388 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
390 * Implemented the SILC Mutex API and SILC Thread API for WIN32
391 in lib/silcutil/win32/.
393 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
395 * Defined SILC Mutex API and SILC Thread API and implemented
396 them for Unix. Affected files are
397 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
398 lib/silcutil/unix/silcunixmutex.c and
399 lib/silcutil/unix/silcunixthread.c.
401 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
403 * Fixed the silc_server_remove_clients_by_server's channel
404 key re-generation. The hash table handling was incorrect
405 and would not work with many channels. Affected file is
408 * Fixed some memory leaks around the server code.
410 * Rewrote the silc_server_get_users_on_channel to support IPv6
411 based Client ID's. Affected file silcd/server.c.
413 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
414 specification. However, a separate document must be written
415 to define the detailed signing procedure and the payload
416 associated with the flag. Defined the flag to the
417 lib/silccore/silcchannel.h as well.
419 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Changed the dynamic tables to static size tables in the
422 lib/silccrypt/silchmac.c.
424 * Removed GCC dependencies from the code. A patch by cras.
426 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Do not show the error "Error receiving packet bla bla"
429 in server if it really was not an error (-2 means that reading
430 is pending). Affected file silcd/server.c.
432 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
434 * Fixed a possible crash in silc_server_remove_clients_by_server
435 in silcd/server.c. Fixed there also some memory leaks.
437 * Fixed the silc_idlist_replace_client_id. It could replace
438 wrong key in the hash table. Affected file silcd/idlist.c.
440 * Do not check whether there are global users on the channel
441 if the channel->global_users is FALSE. Affected functions
442 silc_server_remove_from_one_channel and
443 silc_server_remove_from_channels in silcd/server.c. Also,
444 do not check if the removed client is local as we can be
445 sure that global client was not removed from the channel
446 and checking for global users is not needed.
448 * The silc_server_remove_clients_by_server now re-generates
449 the channel keys correctly for those channels that had
450 clients removed from them. Affected file silcd/server.c.
452 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
454 * Found the reason of random crashes in the server. We weren't
455 ignoring the SIGPIPE signal (which can be sent in write())
456 and it crashed the server. Affected file silcd/silcd.c.
458 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
460 * Assure that sock->user_data is not NULL in the function
461 silc_server_packet_send in silcd/packet_send.c.
463 * Disconnect the remote connection if it could not be added
464 to any ID lists in the server. The affected file is
467 * Check in silc_server_packet_send[_real/dest] that the
468 socket is not disconnecting and ignore the data if it is.
469 Affected file silcd/packet_send.c.
471 * Define inline to __inline on native WIN32 compilation.
472 Affected file includes/silcwin32.h.
474 * Added some explicit type casts for inline code since MSVC
475 require them. Affected files lib/silcutil/silcbuffer.h,
476 lib/trq/silcdlist.h and lib/trq/silclist.h.
478 * Print warning in log files from now on if the packet
479 decryption fails. Affected file silcd/server.c.
481 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Changed the `say' client operation's interface to accept
484 new `type' argument to indicate the type of the message sent
485 by the library. The application may filter the library's
486 messages according the type. The affected file is the
487 lib/silcclient/silcapi.h.
489 * Added two new functions to lib/silcclient/silcapi.h:
490 silc_client_del_client and silc_client_del_client_by_id.
491 Affected file lib/silcclient/idlist.c.
493 * Moved the clientincludes.h from includes/ to silc/ and
494 serverincludes.h from includes/ to silcd/.
496 * The modes for the CMODE and CUMODE are now passed as
497 uint32 for application with COMMAND_REPLY. The affected
498 file is lib/silcclient/command_reply.c.
500 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
502 * /WHOIS without arguments shows client's own information.
503 Affected file lib/silcclient/command.c.
505 * Changed PING to not accept any arguments. The specs
506 says that client can ping only the connected server so
507 requiring an argument is not needed. Affected file is
508 lib/silcclient/command.c.
510 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
512 * Fixed a fatal bug in private message sending and reception
513 encryption and decryption when using private message keys.
514 The implementation was incorrect and did not follow the
515 specification. It causd that some of the message were
516 lost since it did not use the sending and receiving keys
517 as the protocol suggests. This has been fixed and will cause
518 incompatibilities with older clients when sending private
519 message encrypted with private message keys. Affected files
520 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
521 and various other in Irssi SILC Client.
523 Added `responder' boolean argument to the functions
524 silc_client_add_private_message_key[_ske] to indicate when
525 the key is added as responder or initiator of the key
528 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
530 * Removed the silc_ske_check_version function and created
531 a SilcSKECheckVersion callback. Added also a function
532 silc_ske_set_callbacks that is now used to set all SKE
533 callbacks. The callback functions are not given to
534 the SKE functions anymore, but this function is used to
537 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
539 * Added `silc_version' argument to the silc_client_alloc
540 to define the version of the application for the library.
541 The library will use the version string to compare it
542 against the remote host's (usually a server) version
543 string. Affected file lib/silcclient/silcapi.h
545 * Added the KE protocol context to Key Agreement context
546 in client library so that we can abort the SKE if it
547 is in process when we get timeout. Affected file is
548 lib/silcclient/client_keyagr.c.
550 * Do not resolve the client ID forever if it returns in the
551 first time that such client does not exist. This was done
552 for example with private message. Affected file is
553 lib/silcclient/client_prvmsg.c.
555 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Do not add regex.h for WIN32. The affected file
558 includes/silcincludes.h.
560 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
561 not work yet 100%. It generates the DLL's automatically
562 when compiling with --with-win32 under cygwin.
564 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
566 * lib/contrib/regex.c is not compiled on WIN32.
568 * Added silc_net_get_socket_opt function to the
569 lib/silcutil/silcnet.h.
571 * Added includes/silcwin32.h for WIN32 specific includes
574 * Do not use ptime structure or any of the posix process
575 functions on WIN32 in lib/silccrypt/silrng.c.
577 * Added silc_gettimeofday to provide generic function
578 for struct timeval on all platforms. Added the function
579 to lib/silcutil/silcutil.h.
581 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
583 * Moved the lib/silccore/silcsockconn.[ch] to the utility
584 library as they clearly belong there. As a plus side we
585 can make the actual socket connection routines platform
588 Added also new generic function silc_socket_read and
589 silc_socket_write (that used to be silc_packet_[read/write].
590 The implementation of these are platform specific.
592 * Added WIN32 specific routines of silc_socket_[read/write]
593 to lib/silcutil/win32/silcwin32sockconn.c.
595 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
597 * Added preliminary support for native WIN32 compilation under
598 cygwin (using the -mno-cygwin option for GCC) to the
599 ./configure.in.pre. The --with-win32 now prepares the
600 compilation for native WIN32.
602 * Rewrote the SILC Scheduler interface in the file
603 lib/silcutil/silcschedule.h. The scheduler is now context
604 based and does not have anymore any global static scheduler.
605 Moved the Unix scheduler to the lib/silcutil/unix/ directory
606 and created lib/silcutil/win32 directory for WIN32 based
609 * Added Unix specific network routines to the
610 lib/silcutil/unix/silcunixnet.c and the old
611 lib/silcutil/silcnet.c includes now only generic routines.
613 Added WIN32 specific network routines to the
614 lib/silcutil/win32/silcwin32net.c.
616 * Added Unix specific utility functions from the
617 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
619 * Added WIN32 SILC Scheduler to the file
620 lib/silcutil/win32/silcwin32schedule.c. The code is of course
623 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
625 * Do not handle JOIN notify in the server if the target client
626 is not registered (idata->registered == FALSE). The affected
627 file is silcd/packet_receive.c.
629 * Update the nickrec->founder in event_cumode in the Irssi SILC
630 client. Affected file irssi/src/silc/core/silc-channels.c.
632 * Fixed the CUMODE_CHANGE notify handling in the server when
633 server and router are announcing their clients on channels.
634 Now the mode changes are saved and notified correctly. The
635 affected file is /silcd/packet_receive.c.
637 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
638 They really did not replace the cache entry in the ID Cache.
639 Now they do that. Affected file silcd/idlist.c.
641 * Fixed the KICK notify handling in the Irssi SILC client to
642 update the channel records so that the kicked client does not
643 appear to be on the channel. The affected file is
644 irssi/src/silc/core/silc-channels.c.
646 * Always update the conn->current_channel when executing command
647 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
649 * Fixed the KILL notify handling in Irssi SILC client to remove
650 the killed client on all channels.
652 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Fixed the silc_parse_command_line to remove extra spaces
655 from the start and end of the arguments. Affected file is
656 lib/silcutil/silcutil.c.
658 * Cancel and free any active protocol in the function
659 silc_server_close_connection. Affected file silcd/server.c.
661 * Cancel and free any active protocol in the function
662 silc_client_close_connction. Affected file is
663 lib/silcclient/client.c.
665 * Do not execute the KILL command for clients that are in
666 history (ie. they are not in the network). Affected file is
669 * Fixed KILL notify handling, client does not crash anymore.
670 Affected file irssi/src/silc/core/silc-channels.c.
672 * Reduced the default packet buffer size from 2048 to 1024 in
673 lib/silccore/silcpacket.c.
675 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
676 counter to the SKE context that is incresed when the SKE library
677 performs async operation outside the library. If the outside
678 process frees the SKE context and FREED status will be set
679 and the library will detect after the sync operation that the
680 libary is freed. The affected files are
681 lib/silcske/silcske[_status].[ch].
683 * Resolve the client entry information in the function
684 silc_client_channel_message to assure that NULL pointer is not
685 passed as client entry to the application. */
687 * Fixed the task timeout calculation to assure that there is
688 never negative timeouts. The affected file is
689 lib/silcutil/silcschedule.c.
691 * Fixed the channel user mode notification sending in server.
692 It was sent point-to-point to the router (or to server by router)
693 but it needs to be destined to a channel. The routines now
694 supports sending the channel user mode notifys to the channels
695 when announcing clients and channels. Affected files are
696 silcd/server.c and silcd/packet_receive.c.
698 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
699 It did not actually replace the old channel entry in the cache.
700 Affected file lib/silcclient/client_notify.c.
702 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Fixed a possible crash in silc_packet_send_prepare. It now
705 assures always that there is enough space in the buffer and
706 at the tail area of the buffer (for MAC).
708 Fixed the inbound buffer reallocation in silc_packet_read.
709 It was old code and did not handle the reallocation correctly.
712 The affected file is lib/silccore/silcpacket.c.
714 * Fixed buffer overflow in silc_parse_nickname in the file
715 lib/silcutil/silcutil.c.
717 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * make install generates new server keys only if there is not
722 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
724 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
725 Added check that if the NOREPLY is set then we will not send
726 the away message. This avoids infinite loop of away messages
727 if both clients are away. The affected file is
728 lib/silcclient/client_prvmsg.c.
730 * Fixed client crash if /NICK was given without arguments.
731 Affected file lib/silcclient/command.c.
733 * Server does not send the invite list in INVITE command back
734 to the client if the list was not altered. Added this notion
735 to the protocol spec as well. Affected file silcd/command.c.
737 Fixed possible crash in INVITE command by checking the
738 value of silc_server_get_client_route command.
740 * Fixed the INVITE notify type handling. The arguments are now
741 taken in correct order and client does not crash. The affected
742 file is irssi/src/silc/core/silc-channels.c.
744 Removed the "Inviting xxx to channel" message from the
745 client library away and let the application handle it.
746 Affected file lib/silcclient/command.c. Added that message
747 to Irssi SILC client's message formats.
749 * Fixed CMODE command crash in client. It now checks the
750 amount of arguments correctly and does not crash. The affected
751 file is lib/silcclient/command.c.
753 * Do not create new channel automatically in silc_channels_join
754 but check whether the channel by that name already exists.
755 Affected file irssi/silc/core/silc-channels.c.
757 * Do not send the SERVER_SIGNOFF to router if the disconnected
758 entity was the router. Affected file silcd/server.c.
760 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
761 SILC client as it was missing from there.
763 Added the handling of the KICK notify to the Irssi SILC client
764 as it was missing. Added "you have been kicked" message to
765 Irssi SILC client's message modules formats.
767 Added the handing of the KILL notify to the Irssi SILC client
768 as it was missing. Added the kill message module formats
771 The affected file is irssi/src/silc/core/silc-channels.c.
773 * The router did not save the channel mode the server announced.
774 Affected file silcd/packet_receive.c.
776 * Fixed a possible crash in INFO command in server. If the
777 server did not provide the server info it crashed. Affected
778 file silcd/command.c.
780 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Fixed the GETKEY command in the server to check also the
783 global list. Otherwise the GETKEY would not work correctly
784 in normal SILC server. Affected file silcd/command.c.
786 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Fixed GETKEY crash, it crashed if the command did not succseed.
790 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
792 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
793 is now real and not just an macro interface to GMP.
795 Removed the entire GMP from the source tree and imported new
796 NSS MPI library instead. Reason for removing GMP is that it is
797 extremely large and compiles extremely slow. The NSS MPI
798 is only a few files and compiles in less than 10 seconds.
799 The speed is also about the same as GMP. The MPI is imported
802 If the system has GMP installed we will still use the GMP.
803 If it is not then the NSS MPI will be compiled.
805 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
807 * Merged a long nickname (127 characters long) crash bugfix from
808 Irssi CVS tree. Affected file irssi/src/core/misc.c.
810 * Merged a freed memory reference bugfix from Irssi CVS tree.
811 Affected file irssi/src/core/commands.c.
813 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Added the server's public key sving and verification to the
816 server when performing the SKE. This was missing and the
817 remote server's (or router's) public key was accepted without
818 checking whether we have it previously or trust it at all.
819 Affected file silcd/protocol.c.
821 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Check in the silc_server_timeout_remote if protocol is active
824 and make sure that the protocol's final callback is called so
825 that all memory if freed. Affected file silcd/server.c.
827 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * silc_server_whois_send_reply crashed the server if the nickname
830 was 127 characters long. Affected file silcd/command.c.
832 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Added sanity check to the silc_server_new_client. If the hostname
835 is provided inside username then check that the provided hostname
836 really is the same as the resolved one. If the hostname was not
837 resolved then check it from the public key. Affected file is
838 silcd/packet_receive.c.
840 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
841 if the server disconnected us and the connection is not valid
842 anymore. Affected file irssi/src/silc/core/silc-channels.c.
844 * Moved the silc_client_[chmode|chumode|chumode_char] away from
845 the library to the lib/silcutil/silcutil.[ch].
847 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Close log file after open. Affected file
850 lib/silcutil/silclog.c.
852 * Check whether sock == NULL in silc_client_send_packet and return
853 if it is. Affected file lib/silcclient/silcclient.c.
855 * Check rec->entry == NULL in the Irssi SILC Client before
856 sending the channel message. Affecte file is
857 irssi/src/silc/core/silc-servers.c.
859 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Merged a splitted window bugfix from Irssi CVS tree. The
862 affected file is irssi/src/fe-text/textbuffer-view.c.
864 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
865 It did not print nickname.
867 * Improved the distributions system a bit.
869 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
872 irssi/src/fe-text/gui-window.c.
874 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
875 to in-active server. The affected file is
876 irssi/src/silc/core/client_ops.c.
878 * Resolve the client in USERS command reply if the entry does
879 not have username resolved. The affected file is
880 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
881 command to WHOIS command to really resolve stuff. The USERS
882 is not used any more in any critical section so WHOIS can
883 be used even though it might be slower than IDENTIFY.
885 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
888 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Changed the protocol API a bit more consistent in the
891 lib/silccore/silcprotocol.[ch].
893 * Changed the following headers to ROBODoc format:
895 lib/silccore/silcpayload.h
896 lib/silccore/silcprotocol.h
897 lib/silccore/silcsockconn.h
899 All core library headers are now formatted.
901 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
903 * Fixed a bug in Irssi SILC client; do not show that you are
904 server/router operator if you really are not. Affected file is
905 irssi/src/silc/core/client_ops.c.
907 * Renamed silc_command_free_payload to silc_command_payload_free.
908 Affected file lib/silccore/silccommand.h
910 * Added silcmath.h to include the prototoypes of various routines
911 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
914 * Changed the following headers to ROBODoc format:
916 lib/silccore/silcchannel.h
917 lib/silccore/silccommand.h
918 lib/silccore/silcid.h
919 lib/silccore/silcidcache.h
920 lib/silccore/silcmode.h
921 lib/silccore/silcnotify.h
922 lib/silccore/silcpacket.h
923 lib/silcmath/silcmath.h
925 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Added checking to the server code not to start the server if
928 ciphers and stuff are not configured properly. Affected files
929 silcd/serverconfig.[h] and silcd/server.c.
931 * Changed the layout of the header files of the public interfaces
932 in the SILC libraries. The new layout supports ROBODoc
933 documentation tool (and some others) so that it is easy to create
934 a library reference manual. All the other headers and source
935 code must still follow the CodingStyle document. Also source
936 code must not include these ROBODoc stuffs, only the headers.
937 Furthermore, all public interface headers must now be named
938 by using `silc' prefix, example: silcapi.h, silccipher.h.
939 Some files were renamed due to this. All the other headers
940 must not be used as public interfaces. I will update the
941 CodingStyle document later. Changed following headers, so far:
943 lib/silcclient/silcapi.h
944 lib/silccore/silcauth.h
945 lib/silccore/silcprivate.h
946 lib/silccrypt/silcdh.h
948 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Removed silc_client_packet_send_flush from the client library
953 as it is not needed. Affected file lib/silcclient/client.[ch].
955 * Added printing of message of unresolved authentication method
956 to the Irssi SILC client. Added it to the module formats.
957 Removed the same message from the client library.
959 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * Added new distribution feature, DISTLABEL. Every distribution
962 can define own preprocessor label that can be used in the
963 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
964 file distributions, acconfig.h.pre and prepare.
966 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Added Makefile.defines_int to include the actual definitions
969 for Makefile.defines.in. Tested the new distribution system,
970 created distributions and tested installation.
972 * Added AWAY message printing to the Irssi SILC client. Added
973 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
975 * Added SCONNECT command to call the SILC's CONNECT command.
976 Cannot use CONNECT directly since Irssi uses that internally.
977 Affected file irssi/src/silc/core/silc-servers.c.
979 Added ACTION local command. It is same as ME command but takes
980 the channel as mandatory argument.
982 Rewrote some of the Irssi's help files to suite for SILC
985 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added Makefile.defines[.in] that should for now on be included
988 in all Makefile.am file in the source tree. That file includes
989 all common compilation definitions for SILC source tree.
991 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Minor changes to the ./prepare script to change the package
994 name according the distribution name to the configure.in.
996 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Created new distribution system. Added file `distributions'
999 that defines all the distributions that can be created out of
1000 the SILC source tree. The ./prepare script now reads that
1001 file to determine how to prepare the distributions. The
1002 first argument to the ./prepare is the name of the distribution
1003 and second is the version of the distribution. If given
1004 without arguments it creates the default (toolkit) distribution
1005 with the default version (defined in ./prepare).
1007 All Makefile.am files that are subject to the distributions
1008 are now named as Makefile.am.pre. These are ./Makefile.am
1009 and lib/Makefile.am. Others may be changed later.
1011 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1013 * Added invite list, ban list, some key management and connection
1014 error message printing to module formats in the Irssi SILC client.
1016 * Added new silc_client_set_away_message to set the away message
1017 that is back to the person who sent private message. The
1018 affected file lib/silcclient/silcapi.h and the
1019 lib/silcclient/client_prvmsg.c.
1021 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Fixed the private message sending in the Irssi SILC client,
1024 added local command KEY to the Irssi SILC client.
1026 Added key management and key agreement message formats to the
1027 irssi/src/fe-common/silc/module-formats.[ch].
1029 Added USERS (alias WHO) printing, server/router operator
1030 indication and LIST command printing to the module formats.
1032 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Fixed channel joining notify handling, cumode notify handling
1035 from Irssi SILC client.
1037 * Added SILC specific module-formats to the Irssi SILC client so
1038 that SILC specific message hilighting, colors etc is possible.
1039 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1041 Added channel mode, channel user mode, actions, notices,
1042 whois and whowas printing to the the module-formats.c.
1044 * Fixed a bug in channel deletion in the server. The channel
1045 is not left to the cache even if the channel founder auth mode
1046 is set when there are no users anymore on the channel. Affected
1047 file silcd/server.c.
1049 * The silc_net_localhost now resolves the entire hostname including
1050 the domain name. Affected file lib/silcutil/silcnet.c.
1052 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Changed the ask_passphrase client operation to be ascynchronous.
1055 It has now a completion callback and a context that the
1056 application must call after it has got the passphrase from
1057 the user. Affected files lib/silcclient/silcapi.h,
1058 lib/silcclient/protocol.c, lib/silcclient/command.c and
1061 Added SilcAskPassphrase callback that the application calls
1062 to deliver the passphrase to the library.
1064 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1065 The public key verification and especially a certificate
1066 verification is asynchronous procedure.
1068 Added new SILC_SKE_STATUS_PENDING status to indicate the
1069 request is pending and a callback will be called to finalize
1072 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1073 indicate that remote end did not send its public key (or
1074 certificate), even though we require it. Added check for this
1075 condition in the SKE. This was a security bug, now fixed.
1077 Defined new SilcSKEVerifyCbCompletion callback that is called
1078 when the verification process is completed.
1080 The affected files lib/silcske/silcske_status.h and
1081 lib/silcske/silcske.[ch].
1083 * Changed the verify_public_key client operation to be async
1084 as well. Defined SilcVerifyPublicKey callback that is used to
1085 indicate the success of the public key verification process.
1087 Changed the server and client to use the new async client
1090 * Changed the Irssi SILC client's internal scheduler to be called
1091 twice as many times as it used to be. As a result the client
1092 should be a bit faster now. Affected file is
1093 irssi/src/silc/core/silc-core.c.
1095 * Added support to Irssi SILC client of asynchronous public key
1096 verification and passphrase inquiry. Affected file is
1097 irssi/src/silc/core/silc-core.c.
1099 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Do not say "You have left channel %s" in client library.
1102 Moved it to the application. Affected files are
1103 lib/silcclient/command.c and silc/client_ops.c.
1105 * Fixed silc_client_get_clients. Command context was not
1106 duplicated and was freed memory in the callback. Affected
1107 file lib/silcclient/idlist.c.
1109 * Do not say "you are now talking..." on JOIN command in the
1110 client library. The appliation must handle it.
1112 * Do not say ".. changed topic to" in command reply in the
1113 client libary. The application must handle it.
1115 * Fixed TOPIC command sending in the client library.
1117 * Fixed a memory leak in silc_client_command_free in the file
1118 lib/silcclient/command.c.
1120 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Imported a modified version of Irssi client to the source tree.
1123 The Irssi will be used to create a new client called
1124 Irssi SILC. Imported to irssi/.
1126 Added silc_core_init_finish function to the Irssi. Affected
1127 file irssi/configure.in.
1129 A lot changes in the Makefile.ams around the irssi tree.
1131 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Do not rehash if the new size is same as the old size of the
1134 hash table, in the silc_hash_table_rehash*. The affected file
1135 lib/silcutil/silchashtable.c.
1137 * Replaced hash_table_del_by_context calls from the server
1138 (when channel->user_list and client->channels) to the
1139 hash_table_del as it is sufficient and faster.
1141 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Added silc_hash_table_list, silc_hash_table_get and the
1144 SilcHashTableList structure to provide an alternative way to
1145 traverse the hash table. The affected files are
1146 lib/silcutil/silchashtable.[ch].
1148 * Changed the server's idlist routines to use the hash table
1149 routines to optimize the code.
1151 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Replaced the client entry's `channel' list and channel entry's
1154 `user_list' list to hash tables for optimized lookup. Changed
1155 the code to use the hash table interface around the code.
1156 Affected file lib/silcd/idlist.[ch].
1158 * Added `auto_rehash' boolean argument to the function
1159 silc_hash_table_alloc to indicate whether the hash table should
1160 auto-rehash when it thinks is appropriate time. It will
1161 increase the hash table size if the there is twice as much
1162 entries in the table than the size of the table, and will
1163 decrease the size if there are twice as less entries than
1164 the size of the table.
1166 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1170 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * silc_idcache_purge_by_context deletes the entry now by context
1173 as it is supposed to do. Affected file lib/silccore/idcache.c.
1175 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1176 client is not anymore valid (WHOWAS givens the info) and not
1177 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1179 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Removed the `data' and `data_len' arguments from the ID Cache
1182 interfaces and added `name' argument. ID Cache does not handle
1183 anymore the binary data only a names associated with given ID.
1185 * When hashing a Client ID with silc_hash_id the entire ID is
1186 not hashed anymore, instead only the hash of the Client ID is
1187 hashed. This way we can access the Client ID from the cache
1188 with Client ID but with the hash of the ID (which is a hash of
1189 the nickname) as well without any difference in performance.
1191 Added also silc_idcache_find_by_id_one_ext to do one on one
1192 searching when we have the actual ID. Added also function
1193 silc_hash_client_id_compare. The affected files are
1194 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1196 * When hashing the name associated with a ID it is always done
1197 in lowercase. This way we can access the cache without worrying
1198 about case-sensitivity, even though, for example nicknames are
1201 * Fixed a bug in server with channel message sending. It put
1202 wrong ID type as destination ID. The affected file
1203 silcd/packet_send.c.
1205 * silc_idcache_del_by_context now deletes from all hash tables
1206 by context. Affected file lib/silccore/idcache.c.
1208 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Changed the client library to use the new ID Cache interface.
1211 Changes around the source tree.
1213 * Added silc_hash_table_rehash_ext to rehash with specific
1214 hash function. Affected file lib/silcutil/silchashtable.[ch].
1216 * Added silc_hash_string_compare to compare two strings in the
1217 hash table. Affected file lib/silcutil/silcutil.[ch].
1219 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Added new function silc_idcache_del_by_context into the
1222 lib/silccore/idcache.[ch].
1224 * Changed the server's ID list routines to use the new ID Cache
1225 interface. Changes around the source tree.
1227 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Added silc_hash_table_del[_by_context]_ext functions in to the
1230 lib/silcutil/silchashtable.[ch].
1232 Removed silc_hash_table_find_all* routines and added new
1233 silc_hash_table_find_foreach to replace them.
1235 Added silc_hash_table_replace_ext function as extended
1236 replacing function. Separated the simple hash table interface
1237 from the extended hash table interface in the file
1238 lib/silcutil/silchashtable.h.
1240 * Fixed minor bugs and changed it to use some of the new
1241 hash table functions in lib/silccore/idcache.c
1243 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Added new function silc_hash_table_find_all to return all keys
1246 in the hash table by the specified key. As the hash table is
1247 collision resistant it also makes it possible to have several
1248 duplicate keys in the hash table. This function may be used to
1249 find all of the keys from the hash.
1251 Added user_context arguments to the SilcHashFunction,
1252 SilcHashCompare and SilcHashDestructor to deliver user specified
1255 Added new fuctions silc_hash_table_find[_all]_ext to do
1256 extended lookup with specified hash and compare functions and
1257 specified user contexts.
1259 Added new function silc_hash_table_add_ext to add the key
1260 with specified hash function and user context.
1262 Added new function silc_hash_table_foreach to traverse all
1263 entrys in the hash table. Added SilcHashForeach callback
1266 Added new function silc_hash_table_del_by_context to delete
1267 the entry only if the context associated with the key matches.
1269 Affected files are lib/silcutil/silchashtable.[ch].
1271 * Removed silc_hash_[server/client/channel]_id and added just
1272 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1273 silc_hash_id_compare to compare two ID's using as the hash table
1274 comparison function. Added also silc_hash_data to hash
1275 binary data and silc_hash_data_compare to compare it.
1277 * Removed silc_idlist_find_client_by_hash as it is not needed
1278 anymore. Affected file silcd/idlist.[ch].
1280 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1281 to use internally the SilcHashTable. The new ID Cache is a lot
1282 faster than the old one. Some of the ID Cache interface was also
1283 rewritten and obsolete and stupid functions were removed.
1285 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Added entry_count field to the SilcHashTable to keep the number
1288 of the entries in the table. Implemented the function
1289 silc_hash_table_rehash. Added new function
1290 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1292 Fixed a minor bug in silc_hash_table_free.
1294 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1295 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1296 into the lib/silcutil/silcutil.[ch].
1298 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Implemented a collision resistant hash table into the
1301 lib/silcutil/silchashtable[ch]. See the header and the source
1302 for the SilcHashTable API.
1304 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1306 * Merged dotconf version 1.0.2 into lib/dotconf.
1308 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Do not compile anything in lib/silcsim/* if the SIM support
1311 is not enabled. The tree should now compile without problems
1314 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1316 * Compiled the SILC under cygwin. Compiled and tested briefly
1317 without problems. More tests needed. The SIMs didn't compile
1320 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1322 * Fixed possible crash in silc_get_username in the
1323 lib/silcutil/silcutil.c.
1325 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Fixed a va_arg in silc/client_ops.c.
1329 * Oops, RC5 routines were named AES and caused some problems
1330 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1332 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Added new SilcIDIP structure into the lib/silccore/id.h and
1335 replaced the old `ip' fields from all SILC ID's to that type.
1336 This is a step towards IPv6 support.
1338 The silc_id_get_len takes now the ID as an extra argument.
1339 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1340 both IPv4 and IPv6 based ID's.
1342 The affected files are lib/silccore/id.[ch] and other files
1343 around the tree using these routines.
1345 * Removed the ID length arguments in server from various
1346 silc_server_send_notify_* routines -> they are not needed
1349 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Fixed memory leak in silc_encode_pem_file in the file
1352 lib/silcutil/silcutil.c.
1354 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1356 * Check minor version as well in the SKE. Affected files are
1357 silcd/protocol.c and lib/silcclient/protocol.c.
1359 * Added --identifier option to the server so that an identifier
1360 can be when creating the public key for the server. Affected
1361 file is silcd/silcd.c.
1363 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1364 lib/silccrypt/silcpkcs.c.
1366 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Register default ciphers and stuff when using -C option with
1369 the server. Affected file sildc/silcd.c.
1371 * Put back the servers public key filename format, it is better
1372 than the new one. For now, the client keys are saved with the
1373 new filename format. The affected file silc/client_ops.c.
1375 * Implemented the Cipher API for the rest of the ciphers that
1376 did not implement it or implemented it the wrong way.
1378 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Register default ciphers and stuff when using the -S option
1381 in the client. Affected file silc/silc.c. Same also when
1382 creating new key pair with -C option.
1384 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1386 * Fixed the silc_verify_public_key client operation function to
1387 save the public keys differently. The fingerprint is now
1388 used as filename and not the hostname. This way also the
1389 client keys are saved uniquely and not with hostnames. The
1390 affected file is silc/client_ops.c.
1392 * Trimmed the silc_hash_fingerprint function to remove extra
1393 whitespaces from the end of the fingerprint. The affected
1394 file is lib/silccrypt/silchash.c.
1398 * Added silc_cipher_register_default function to register all
1399 default ciphers. It can be used when configuration files
1400 does not exist and the application does not want any specific
1401 ciphers in any specific order.
1403 The SilcDList is now used as silc_cipher_list dynamically
1404 allocated cipher list. Removed the static list all together
1405 and now all ciphers must be allocated to the dynamic list.
1406 The silc_cipher_alloc routine was changed to check only the
1409 All silc_cipher_* routines that used to return int returns
1412 The affected files lib/silccrypt/silccrypt.[ch].
1414 * The same thing was done to silc_hash_* as for silc_cipher_*
1415 routines. Affected files lib/silccrypt/silchash.[ch].
1417 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1418 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1419 Added also silc_pkcs_[un]register[_default] functions.
1420 Removed the data_context from the PKCS API.
1422 * Added silc_hmac_register_default function to register default
1423 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1424 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1425 to unregister all hmacs at once.
1427 * Register the default ciphers, hash functions, PKCSs and HMACs
1428 if client's configuration file does not exist. The affected
1431 * The client did not load the hash functions from the SIM
1432 modules at all. Added support for this. Affected file is
1433 silc/clientconfig.c.
1435 * When decoding public key with silc_pkcs_public_key_decode, check
1436 the supported algorithm only if PKCS are registered. Affected
1437 file lib/silccrypt/silcpkcs.c. The same was done with the
1438 silc_pkcs_private_key_decode.
1440 * Fixed the SILC List routines to keep the list always in order.
1441 It used to change the list's order when traversing the list but
1442 not it preserves the order. Affected file lib/trq/silclist.h.
1444 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1446 * Added the client library to use the SilcSocketConnection's
1447 reference counter (by silc_socket_dup) to prevent the bug that
1448 the socket object may be freed underneath async operation.
1450 * The name resolv library checking fixes in the configure.in.pre.
1453 * Created new version of the protocol drafts for future
1454 development. The -03 drafts are the ones that will be changed
1455 in the trunk now and the -02 will remain as they are.
1457 * Send list of CUMODE notifys to the router when announcing
1458 the channel users to the router. Affected file silcd/server.c.
1459 If the router receiving channel founder CUMODE for a channel
1460 that already has channel founder it will send CUMODE notify
1461 to the sender to remove the channel founder rights from the
1462 announced client. Affected file silcd/packet_receive.c.
1464 * The CUMODE notify may now use Server ID as well as the entity
1465 who changes the mode. Updated protocool specs.
1467 * Updated INSTALL and README files.
1469 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * New web pages in the http://silc.pspt.fi. The pages was
1476 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Implemented the [DenyConnectin] config section in the server.
1479 Added silc_server_config_denied_conn to check whether incoming
1480 connection is denied. Affected file silcd/serverconfig.[ch].
1482 * Do not check the ports when checking the incoming configuration
1483 data if the port is 0, meaning any. Affected file is
1484 silcd/serverconfig.c.
1486 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Fixed buffer overflow in silc_string_compare in the file
1489 lib/silcutil/silcutil.c.
1491 * Fixed double free in silc_server_command_leave in the file
1494 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Fixed the version checking in the server. Affected file is
1499 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Fixed the configuration data fetching when accepting new
1502 connections in the server. Affected file silcd/server.c.
1504 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Added `sender_entry' argument to the function
1507 silc_server_packet_relay_to_channel so that we can check
1508 whether some destination actually belongs to the same route
1509 the sender belongs (ie, we must not resend the packet to the
1510 sender). Affected file silcd/packet_send.[ch].
1512 * Added `servername' field to the SilcClientEntry in the server
1513 to hold the name of the server where client is from. Affected
1514 file is silcd/idlist.h.
1516 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1518 * Moved the channel message encrypting in the router betwen
1519 router connections from silc_server_channel_message to the
1520 silc_server_packet_relay_to_channel since we want to check
1521 whether we have anybody channel before encrypting anything.
1522 Affected files silcd/packet_[receive/send].c.
1524 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1526 * Fixed the [AdminConnection] server config section to support
1527 multiple entries. Affected file silcd/serverconfig.c.
1529 * Added support into the server to check the validity of the
1530 incoming connection before executing any KE or authentication
1533 * The connection configuration is now saved to the KE and
1534 connection auth protocol contexts and not fetched anymore in
1535 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1537 * The local hosts listenning address and port is also resolved
1538 now when starting the server. We want to have the socket object
1539 to include the real address and port for the listener. Added
1540 new function silc_net_check_local_by_sock into the files
1541 lib/silcutil/silcnet.[ch].
1543 * Fixed a broadcast bug in server -> do not broadcast if we
1546 * Fixed a routing bug. Do not route broadcast packets ever.
1547 Broadcast packets must be processed always and not routed since
1548 they may be destined to some other host than yourself and thus
1549 would get routed without no good reason. Affected file is
1552 * Added function silc_server_config_is_primary_route to check
1553 whether primary router connection has been configured (a router
1554 configuration that we are initiating). If there is not, we
1555 will assume that there is only two routers in the SILC network
1556 and we will use the incoming router connection as our primary
1557 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1559 * Changed the order of the broadcasting. Broadcast _after_ the
1560 packet has been processed not before. Affected file is
1563 * Fixed a [ClientConnection] parsing bug. The port was never
1564 parsed correctly thus resulting to port 0. Affected file
1565 silcd/serverconfig.c.
1567 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1568 argument and did not set the broadcast packet flag. Affected
1569 file silcd/packet_send.c. Fixed same bug in the function
1570 silc_server_send_notify as well.
1572 * If we receive NEW_ID packet for our own ID in the server, ignore
1575 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Removed the nickname from the Private Message Payload.
1580 Updated the code and the protocol specs.
1582 * Updated protocol specs for submitting to the IETF.
1584 * Tweaked the Random Number Generator a bit. Affected file
1585 lib/silccrypt/silcrng.c. Exported a new function
1586 silc_rng_[global]_add_noise which can be used to add more
1589 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1591 * Do not parse packets with different timeout when protocol
1592 is active -> may cause problem with rekey. Affected file
1595 * When server receives signoff notify it must not create
1596 new channel key if the client is on any channels since the
1597 sender of the signoff notify will create it.
1599 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Added printing of error messages during SKE protocol from the
1602 failure packet sent by server during SKE. Affected file
1605 * Removed the client's failure_callback handling with timeout
1606 and handle it immediately when received.
1608 * The SKE library returned wrong type in SUCCESS and FAILURE
1609 packets. They must be 32 bit MSB not 16 bit MSB.
1611 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Ok, rewrote the logic of the re-key and now it seems to work.
1614 I tested it on high traffic with frequent re-keys without
1615 problems. Added hmac_receive (and renamed hmac to hmac_send)
1616 in SilcClientConnection in lib/silcclient/client.h and
1617 in SilcIDListData in silcd/idlist.h. Also, removed the
1618 SilcPacketParserContext's cipher and hmac fields as they are
1619 not needed anymore and actually caused some problems when
1620 the ciphers and hmac's changed underneath the packet parser.
1622 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * If re-key protocol is active then process the incoming packets
1625 synchronously since we must assure that icoming packets encrypted
1626 with the old key is processed before the new keys is set to
1627 use. This is true other packets than for REKEY packets.
1628 Affected file silcd/server.c. The same was done to client library
1629 as well, affected file lib/silcclient/client.c.
1631 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Fixed bug in client and server to accept the force send if
1634 the packet is send from silc_[server/client]_packet_process
1635 function. Otherwise the packets are never delivered, oops.
1637 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1639 * Disable force sending of packets when REKEY protocol is active.
1640 We must assure that no packet is sent directly when rekey is
1641 performed. All packets must be sent through packet queue.
1642 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1643 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1644 function is silc_[server/client]_packet_send_real to check
1647 * Replaced the SIM paths from example config files to
1648 /usr/local/modules. Also, make install creates now
1649 /usr/local/silc/logs directory to hold all the SILC server
1652 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

1663 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * When MAC computation fails the silc_packet_decrypt returned 0
1666 even though it was supposed to return -1. Fixed this. The
1667 affected file is lib/silccore/silcpacket.c.
1669 * Do not replace the config files in /etc/silc (in make install)
1670 if they already exist. Affected file ./Makefile.am.
1672 * Do not send re-key packets immediately but through packet queue.
1673 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1675 * Changed silc_net_check_host_by_sock to return FALSE if the
1676 IP/DNS could not be resolved. Though, it returns the IP address
1677 now even if it could not resolve it (but returns also FALSE).
1678 Affected file lib/silcutil/silcnet.[ch].
1680 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Added silc_pkcs_decode_identifier to decode the public key's
1683 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1684 Added also silc_pkcs_free_identifier. Added also new context
1685 SilcPublicKeyIdentifier.
1687 * Added -S option to the silc client. It is used to dump the
1688 contents of the specified public key file.
1690 * Changed the PKCS api to return the public key length when
1691 setting the public key.
1693 * Fixed a fatal bug in the public and private key file loading.
1694 Affected file lib/silccrypt/silcpkcs.c.
1696 * Execute the packet parsing for client with zero (0) timeout
1697 if the protocol is active. Affected file silcd/server.c.
1699 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Made the key generation options to the silcd program. Added
1702 -C option, equivalent to client's option.
1704 * Added new [ServerKeys] config section to the server. It
1705 configures the server's public and private key.
1707 * Defined generic Public Key Payload into the protocol
1708 specification to send specific type of public keys and
1711 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1712 public key or certificate.
1714 * Implemented the GETKEY command to the server and to the
1715 client library and on user interface.
1717 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Made preliminary `make install' work.
1721 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1723 * Added SilcServerRekey context into silcd/idlist.h.
1725 * Added the PFS support as defined in the specification to the
1726 SKE protocol. Affected files lib/silcske/*.c.
1728 * Added `ske_group' field to the SilcServerRekey context to hold
1729 the number of the SKE group that is used with PFS in re-key.
1730 Affected file silcd/idlist.h.
1732 * Added PFS re-key support to the server. Affected file is
1735 * Added silc_protocol_cancel to cancel execution of the next
1736 state of the protocol. Affected file is
1737 lib/silccore/silcprotocol.[ch].
1739 * Added the re-key support with and without PFS to the client
1740 library. Re-key is performed once in an hour, by default.
1742 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1743 Added silc_client_rekey_callback and silc_client_rekey_final.
1744 Affected files are lib/silcclient/protocol.[ch] and
1745 lib/silcclient/client.[ch].
1747 * Removed the `hmac_key' and `hmac_key_len' fields from the
1748 SilcClientConnection structure; not needed. Affected file is
1749 lib/silcclient/client.h.
1753 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Do not ask whether user wants to use the negotiated private key
1756 for private messages, just use it. Affected file is
1757 silc/local_command.c.
1759 * Added `send_enc_key' and `enc_key_len' fields to the
1760 SilcIDListData structure since they are needed in the re-key
1761 phase. Affected file is silcd/idlist.[ch].
1763 * Implemented the simple re-key protocol into the server.
1764 Affected files silcd/server.c and silcd/protocol.[ch]. The
1765 re-key will be performed once in an hour, by default.
1767 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1768 Added silc_server_rekey, silc_server_rekey_callback and
1769 silc_server_rekey_final.
1771 * Removed Tunneled flag from the protocol. Updated the code
1772 and the specifications.
1774 * Adde `pfs' field to the SilcIDListData to indicate whether
1775 the PFS is to be performed in the re-key. Affected file is
1778 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1781 int64 of at least the xintXX size. If void * is less that 4
1782 bytes uint32 * will be used. Defined bool as boolean.
1784 * Changed _ALL_ unsigned long and unsigned int to uint32,
1785 unsgined short to uint16 in the source tree.
1787 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1788 not handle clients that has entry->data.registered == FALSE.
1789 They are not in the network anymore. Affected file is
1792 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Implemented the sending of the SERVER_SIGNOFF notify in the
1795 server. Affected file is silcd/server.c.
1797 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1798 Added also silc_notify_payload_encode_args into the
1799 lib/silccore/silcnotify.[ch].
1801 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1802 Affected file silcd/packet_receive.c.
1804 * Implemented the SERVER_SIGNOFF notify handling in the client
1805 library. Affected file lib/silcclient/client_notify.c. Also,
1806 implemnted the printing of the SERVER_SIGNOFF info to the
1807 application. Affected file silc/client_ops.c.
1809 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1810 if the deleting was successful. Affected file silcd/idlist.[ch].
1812 * Added support for public key authentication in the connection
1813 authentication protocol in the client library. Affected file
1814 lib/silcclient/protocol.c.
1816 * Changed the server's silc_idlist_get_clients_by_* interface
1817 to support already allocated array so that new entries may be
1818 added to pre-allocated array. Affected file silcd/idlist.[ch].
1819 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1820 and command replies.
1822 * All command reply functions in the server now calls the
1823 pending command callback even if error occured. This way the
1824 error will be delivered to the client as well. Affected files
1825 silcd/command.c and silcd/command_reply.c.
1827 * Fixed INFO command to return local server's info if no server
1828 was provided. Affected file lib/silcclient/command.c.
1830 * Removed RESTART command for good. Updated the code and the
1833 * Rewrote parts of the task system. It is a bit simpler now.
1834 Removed unsued task priorities. The affected files are
1835 lib/silcutil/silctask.[ch].
1837 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Moved the USERS printing from the library to the application.
1840 Affected files lib/silcclient/command.c and silc/client_ops.c.
1842 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * Added channel key re-key support. The re-key is perfomed
1847 only by the router and is done once in an hour. Added `rekey'
1848 field to the SilcChannelEntry in the server. Affected files
1849 silcd/server.c and silcd/idlist.h.
1851 * Added silc_task_unregister_by_context into the file
1852 lib/silcutil/silctask.[ch].
1854 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Added SILC_UMODE_GONE mode to indicate when the client is not
1857 present in the SILC network. Added also support to the local
1858 command AWAY that will set this mode. Added support of showing
1859 "xxx is gone" in WHOIS command. The USERS command shows the
1860 gone status as well.
1862 * Fixed setting server and router operator privileges in the
1863 server's UMODE command. Affected file silcd/command.c.
1865 * Merged the SKE KE1 and KE2 payloads into one payload. The
1866 new KE payload is equivalent to the old KE2 payload.
1868 Cleaned up the SKE Start Payload parsing. It now uses the
1869 simple buffer unformatting to do the parsing. A lot faster
1872 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1873 to the SKE that is used to indicate whether both of the SKE
1874 parties should perform authentication. By default only the
1875 responder performs authentication. By setting this flag also
1876 the initiator must do authentication. By default it is unset
1877 since in normal SKE case, client to server connection, only
1878 the responder should do authentication. When doing SKE between
1879 two clients both should perform authentication. Updated the
1880 code and the protocol specs.
1882 * A little fix to IDENTIFY command in the server. Search the
1883 client first by hash not nickname. Affected file is
1886 * Fixed the silc_client_close_connection to support closing
1887 the client to client connections wihtout deleting too much
1888 data. Affected file lib/silcclient/client.c.
1890 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1891 are received if protocol used to be active but is not anymore
1892 the application would crash due to NULL pointer dereference.
1893 Affected files silcd/server.c and lib/silcclient/client.c.
1895 * Added `hash' field to the SilcClientConnection to include
1896 the hash function negotiated in the SKE protocol.
1898 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1899 to set the channel founder authentication data. A client can
1900 claim the founder rights later by providing the authentication
1901 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1902 This way the channel founder can regain the channel founder
1903 privileges even it is left the channel. This works only on
1904 local server and the client must be connected to the same
1905 server to be able to regain the founder rights. Updated the
1906 protocol specs accordingly.
1908 Added support to the CMODE command in the client to set the
1909 founder auth data. Read the README to see how to set it.
1911 Added support to the CUMODE command to claim the founder
1912 rights. Read the README to see how to do it.
1914 Added support for the founder authentication to the Channel
1915 Entry in the server. Affected file silcd/idlist.h.
1917 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1918 server's CMODE command. Affected file silcd/command.c.
1920 * Added the following new functions into lib/silccore/silcauth.[ch]:
1921 silc_auth_get_method and silc_auth_get_data.
1923 * The server now saves the remote hosts public key to the
1924 SilcIDListData pointer. Affected file silcd/protocol.c.
1926 * The normal server now does not remove the channel entry from
1927 the cache if the founder authentication data is set. It used
1928 to remove it if the founder was the last one on the channel on
1929 the server and left the channel. The auth data is saved and
1930 if the channel is re-joined later the old entry is used with
1931 the old auth data. Affected files silcd/command_reply.c and
1934 * Removed the `pkcs' field from the SilcIDListData structure
1935 in the server; it is not used. Affected file silcd/idlist.h.
1937 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Fixed packet processing on slow links. Partial packets were
1940 never re-processed because the incoming data buffer was cleared
1941 by the application. Application must not directly clear the
1942 sock->inbuf, the packet processing routines handle it. Fixed
1943 this in client library and in server.
1945 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1947 * Fixed the WHOIS and IDENTIFY send reply function to really
1948 check whether to send list or just one entry. Affected file
1951 * Cleaned up the LEAVE command's channel key distribution. The
1952 affected file silcd/command.c.
1954 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1955 can enforce the channel mode as well. In that case the ID
1956 includes the ID of the server. The code now enforces the
1957 mode change if the router have different mode than the server.
1959 * The notify client operation with CMODE_CHANGE notify can now
1960 return NULL client_entry pointer if the CMODE was not changed
1961 by client. Application must check for this.
1963 * Added <Server ID> argument to INFO command to support server
1964 info fetching by Server ID.
1966 * Added silc_server_announce_get_channel_users to get assembled
1967 packets of channel users of the specified channel. Affected
1968 file silcd/server.[ch].
1970 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1971 was freed underneath the ID Cache.
1973 * Re-announce clients when the server received CHANNEL_CHANGE
1974 notify from the router. Affected file silcd/packet_send.c.
1976 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1979 crashed since it did not handle the fact that there is no cipher
1980 called "3" and didn't check the error condition. Now fixed.
1982 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1983 flag. It can be used to send message requests.
1985 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Implemented the RESTART command in the client.
1989 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1990 notice type messages. Added notice printing to the user
1993 * The channel keys are not re-generated if the channel's mode
1994 is PRIVKEY, ie private key on the channel exists. Affected
1995 files silcd/server.c and silcd/command.c.
1997 * Fixed a little bug in channel message delivery when channel
1998 private keys are set in the server. Affected file is
1999 silcd/packet_send.c.
2001 * Changed the setting on channel->on_channel = TRUE from the
2002 silc_client_save_channel_key to the JOIN command reply. The
2003 key payload is not received if the private channel key is set.
2004 Affected file lib/silcclient/command_reply.c and the
2005 lib/silcclient/client_channel.c.
2007 * When the CMODE_CHANGE notify is sent and the channel private
2008 key mode is removed the channel key must be re-generated in
2009 other cells as well. Added this support for the router in the
2010 silcd/packet_receive.c.
2012 * Added new local command NOTICE to send notice message on
2013 channel. Affected file silc/local_command.[ch].
2015 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Added new local command ME to the client. It is used to send
2018 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2019 some action. Affected file silc/local_command.[ch].
2021 * Changed channel_message and private_message client operations
2022 to deliver the message flags to the application. Added also
2023 the `flags' arguments to the silc_client_send_channel_message
2024 and silc_client_send_private_message functions. Affected file
2027 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Redefined the Private Message Payload to support private message
2030 keys and to support the new private message flags. Updated
2031 the protocol specs. Flags makes it possible to have for example
2032 CTCP style messages.
2034 * Added new type SilcPrivateMessagePayload and defined an API
2035 for it in the lib/silcclient/silcprivate.[ch].
2037 * Tested private message private keys successfully. Tested the
2038 private message key set, unset and list commands with the new
2041 * Redefined the Channel Message Payload to include the channel
2042 message flags (equal with private message flags) to support
2043 for example CTCP style messages.
2045 * Defined some of the message (for channel and private message)
2046 flags. Updated the protocol specs and added the flags to the
2047 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2049 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2051 * Added SilcKeyAgreementStatus type to the key agreement routines
2052 to indicate the current status and error if one occured.
2053 The status types are defined in the lib/silcclient/silcapi.h.
2055 * Added new local command KEY that is used to set and unset private
2056 keys for channels, set and unset private keys for private messages
2057 with remote clients and to send key agreement requests and
2058 negotiate the key agreement protocol with remote client. The
2059 key agreement is supported only to negotiate private message keys,
2060 it currently cannot be used to negotiate private keys for channels,
2061 as it is not convenient for that purpose.
2063 * Fixed a minor pending callback setting bug in the function
2064 silc_client_get_client_by_id_resolve, now the function works.
2065 Affected file lib/silcclient/idlist.c.
2067 * Added function silc_net_get_local_port to get local bound
2068 port by socket. Added to lib/silcutil/silcnet.[ch].
2070 * Added `sockets' and `sockets_count' fields to the SilcClient
2071 object. They hold the sockets of the listenning sockets in
2072 the client. Listenning sockets may be for example the key
2073 agreement server. Affected file lib/silcclient/client.[ch].
2074 Added functions the silc_client_add_socket and the
2075 silc_client_del_socket. They are exported to the application
2078 * Added ~./silc/clientkeys to support other client's public keys.
2080 * Renamed verify_server_key client operation to verify_public_key
2081 and added one argument to indicate the type of the connection
2082 (server, client etc.).
2084 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added silc_server_connection_auth_request to handle the
2087 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2088 silcd/packet_receive.[ch].
2090 * Added silc_server_send_connection_auth_request into the
2091 silcd/packet_send.c to send the connection auth request packet.
2093 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2096 * Fixed the public key authentication in responder side in the
2097 server. The `auth_data' pointer includes the SilcPublicKey
2098 not the path to the public key. Affected file silcd/protocol.c.
2100 * Implemented the public key authentication in the initiator side
2101 in the server. Affected file silcd/protocol.c.
2103 * Removed the [RedirectClient] config section from the server
2104 configuration. Is not needed and I don't want to implement it.
2106 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Cleaned up the CMODE command in the server. It now works
2109 correctly and supports all the modes defined in the protocol.
2110 Affected file is silcd/command.c.
2112 * Added `hmac_name' field to the SilcChannelEntry in the server
2113 to hold the default HMAC of the channel. It can be set when
2114 creating the channel (with JOIN command). Affected files
2117 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2118 type to indicate the change of the current cipher and hmac
2119 on the channel. Client can safely ignore the <cipher> argument
2120 (if it chooses to do so) since the CHANNEL_KEY packet will
2121 force the channel key change anyway. The <hmac> argument is
2122 important since the client is responsible of setting the new
2123 HMAC and the hmac key into use.
2125 * Fixed the CMODE command in the client library as well.
2127 * Tested CMODE command in router environment successfully.
2129 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Show the version of the remote client (or server) when connecting
2132 to the server. It is logged to the log file. Affected file
2133 is silcd/protocol.c.
2135 * Fixed the KILLED notify handling in the client library. The
2136 client must be removed from all channels when receiving the
2139 Also, do not remove the client entry when giving the KILL
2140 command but when the KILLED notify is received.
2142 * Removed silc_idlist_find_client_by_nickname from the server.
2143 Not needed anymore. Affected files silcd/idlist.[ch].
2145 * Implemented the CHANNEL_CHANGE notify type handling to the
2146 server. Affected file silcd/server.c.
2150 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Added silc_server_send_notify_invite to send the INVITE
2153 notify between routers.
2155 * Implemented the INVITE command correctly to the server.
2157 * Implemented the INVITE notify type handling in the server.
2159 * Implemented the INVITE command to the client library and on the
2162 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Added function silc_server_get_client_resolve to find the
2165 client entry by ID from all ID lists and then resolve it
2166 (using WHOIS) if it cannot be found. Affected file is
2169 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Implemented the BAN command to the client library.
2173 * The JOIN command in the server now checks the invite list
2176 * Changed the silc_command_reply_payload_encode_va and the
2177 silc_command_payload_encode_va to support that if argument is
2178 NULL it ignores and checks the next argument. Affected file
2179 lib/silccore/silccommand.c.
2181 * Added silc_server_send_notify_ban to send the BAN notify
2182 type between routers.
2184 * Chaned the silc_notify_payload_encode to support that if
2185 argument is NULL it ignores and checks the next argument.
2186 Affected file lib/silccore/silcnotify.c.
2188 * Tested ban lists in router environment successfully.
2190 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Implemented BAN command to the server, in silcd/command.[ch].
2194 * Removed the BAN and INVITE_LIST modes from the CMODE command
2197 * Added function silc_string_match to regex match two strings.
2198 Affected files lib/silcutil/silcutil.[ch].
2200 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Redefined parts of the SilcChannelEntry in the server to support
2203 the new ban and invite lists.
2205 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Redefined the INVITE command. The same command can be used to
2208 invite individuals to the channel but also to manage the invite
2209 list of the channel (to add to and remove from the invite list).
2210 Updated the protocol specs.
2212 * Added new command SILC_COMMAND_BAN that can be used to manage
2213 the ban list of the channel. Updated the protocol specs.
2215 * Removed the channel modes: the SILC_CMODE_BAN and the
2216 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2217 in the CMODE command. The equivalent features are now available
2218 using INVITE and BAN commands. Updated the protocol specs.
2220 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2221 in the network about change in the current ban list. The notify
2222 type is not used by the client.
2224 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2225 support the invite lists.
2227 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Added new function silc_string_regexify that converts string
2230 including wildcard characters into regex string that can
2231 be used by the GNU regex library. Added into the file
2232 lib/silcutil/silcutil.[ch].
2234 Added silc_string_regex_combine to combine to regex strings
2235 into one so that they can be used as one regex string by
2236 the GNU regex library. Added into the file
2237 lib/silcutil/silcutil.[ch].
2239 Added silc_string_regex_match to match two strings. It returns
2240 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2242 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Imported GNU regex to the soruce tree into lib/contrib.
2245 Fixed some compiler warning from the regex.c.
2247 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Fixed MOTD command in the server to work in router environment.
2251 * Fixed the MOTD command in the client library to support
2252 the server argument in the command.
2254 * Added `nickname_len' argument to the silc_idlist_add_client
2255 in the server, as the `nickname' argument may be binary data
2258 * Added silc_idlist_get_channels to return all channels from
2261 * Implemented LIST command to the server. Affected file is
2264 * Implemented the LIST command to the client library and on the
2267 * Added [<user count>] argument to the LIST command reply.
2268 With private channels the user count is not shown.
2270 * Updated TODO and README.
2272 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * The client entry's data.registered must be TRUE even with
2275 global client entry on global client list. The data.registered
2276 is used to check whether the client is anymore in the network,
2277 for example with WHOWAS command so it must be valid.
2279 * Fixed the WHOWAS command in the server. It now actually works
2280 in router environment. Added function into silcd/command_reply.c
2281 silc_server_command_reply_whowas_save.
2283 * Added silc_idlist_purge function to the silcd/idlist.c
2284 to periodically purge the ID Cache.
2286 * Fixed INFO command in the server. It works now in router
2287 environment. Added <server name> argument to the INFO command
2288 reply. Updated the protocol specs.
2290 * Fixed minor bug in silc_idcache_purge to not purge if the
2291 expire value is zero.
2293 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2294 they were buggy because of the WHOWAS information.
2296 * Fixed local command MSG to handle the async resolving of
2297 the remote client properly. It used to fail the first MSG.
2298 Affected file silc/local_command.c.
2300 * Added `data_len' field to SilcIDCache context.
2302 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Update TODO. Todo in commands in the server.
2306 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2309 used by routers as broadcast packet to inform other routers
2310 about the changed user mode.
2312 Implemented the notify handling in the server. Affected file is
2313 silcd/packet_receive.c. Added the function
2314 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2316 * Added new generic Channel Payload and deprecated the New Channel
2317 Payload. The New Channel Payload is now the generic Channel
2320 * Added new argument `mode' to the silc_server_send_new_channel
2321 as it is required in the Channel Payload now.
2323 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2324 and created a new and real SilChannelPayload to represent the
2325 new generic Channel Payload. Implemented the encode/decode
2326 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2328 * Added silc_server_get_client_channel_list to return the list
2329 of channels the client has joined for WHOIS command reply.
2330 Affected file silcd/server.[ch].
2332 * Implemented the channel list sending in the WHOIS command reply
2333 in server and in the client.
2335 Implemented the channel list displaying on the user interface
2336 as well. Affected file silc/client_ops.c.
2338 * Added silc_channel_payload_parse_list to parse list of Channel
2339 Payloads. It returns SilcDList list of SilcChannelPayloads.
2340 Client for example can use this function to parse the list of
2341 channels it receives in the WHOIS command reply. The caller
2342 must free the list by calling silc_channel_payload_list_free.
2343 Affected files lib/silccore/silcchannel.[ch].
2345 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Added one new argument <user mode> to the WHOIS command reply
2348 to return the mode of the user in SILC. Updated the protocol
2351 Implemented it to the server and client.
2353 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Fixed the mode printing on the user interface on joining.
2356 Affected file silc/client_ops.c.
2358 * Implemented the UMODE command and user modes in general to the
2359 client library and to the user interface.
2361 * Implemented the UMODE command to the server.
2363 * The server now sends UNKNOWN_COMMAND error status if client sends
2364 unknown command. Affected file silcd/command.c.
2366 * All server commands now handle the command identifier the right
2367 way when sending the command reply to the client. The client can
2368 use to identify the command replies with the identifier.
2370 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Added silc_server_get_client_route to resolve the route to
2373 the client indicated by the client ID. Affected file is
2376 * Added silc_server_relay_packet as general function to relay
2377 packet to arbitrary destination. This deprecates functions
2378 like _send_private_message_key, _relay_notify etc. Affected
2379 file is silcd/packet_send.[ch].
2381 Removed silc_server_send_key_agreement,
2382 silc_server_send_private_message_key and
2383 silc_server_packet_relay_notify functions from the file
2384 silcd/packet_send.[ch].
2388 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2389 server. Affected file silcd/packet_receive.[ch].
2391 * Implemented the KILL command to the client. Implemented the
2392 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2393 Affected files lib/silcclient/command[_reply].c and
2394 lib/silcclient/client_notify.c. Implemented the KILL notify
2395 printing in the user inteface.
2397 * Fixed a lot silc_parse_nick memory leaks from the client
2398 library in the file lib/silcclient/command.c.
2400 * Changed the silc_server_send_notify_on_channels's `sender'
2401 argument from SilcSocketConnection to SilcClientEntry to
2402 check the sender as entry and not as connection object and not
2403 to send to the client provided as argument. The affected file
2404 is silcd/packet_send.[ch].
2406 * The notify packets that are destined directly to the client used
2407 to not to be processed by the server. Now changed that and the
2408 server processes all notify packets. After relaying the packet
2409 to the client the notify packet is processed in the server.
2411 * The silc_server_free_client_data now checks whether there is
2412 pending outgoing traffic for the client and purges the data to
2413 the network before removing the client entry.
2415 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2418 an client is killed from the SILC Network. Updated the protocol
2421 Added new function silc_server_send_notify_killed to the
2422 silcd/packet_send.[ch].
2424 * Added function silc_server_packet_relay_notify to relay notify
2425 packets that are destined directly to a client. In this case
2426 the server does not process the notify packets but merely relays
2427 it to the client. Affected file silcd/packet_send.[ch].
2429 Added also silc_server_packet_process_relay_notify to check
2430 whereto relay the notify. Affected file is
2431 silcd/packet_receive.[ch].
2433 * Implemented the KILL command to the server.
2437 * Added the backup schema desgined last fall to the protocol
2438 specs for everyone to see. The specification is in the
2439 *-spec-xx.txt draft and the packet type definitions for the
2440 backup routers is in *-pp-xx.txt draft. Thusly, added also
2441 new packet type SILC_PACKET_CELL_ROUTERS.
2443 * A big security problem in the implementation discovered. The
2444 signoff of an client did not cause new channel key generation
2445 which it of course should've done. The channel keys must be
2446 always re-generated when client leaves (or signoffs) the channel.
2447 The silc_server_remove_from_channels funtion now handles
2448 the channel key re-generation.
2450 * Added `sender' argument to the silc_server_send_notify_on_channels
2451 to not to send the client provided as argument. Affected file
2452 silcd/packet_send.[ch].
2454 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Implemented OPER and SILCOPER commands into the server and
2459 * Added silc_auth_verify and silc_auth_verify_data to verify
2460 the authentication directly from the authentication payload.
2461 It supports verifying both passphrase and public key based
2462 authentication. Affected file lib/silccore/silcauth.[ch].
2464 * Added `hash' field to the SilcIDListData structure. It is the
2465 hash negotiated in the SKE protocol. Affected file is
2468 * Slight redesigning of the SilcAuthPayload handling routines.
2469 Do not send SilcPKCS but SilcPublicKey as argument.
2471 * Implemented the public key authentication support to the
2472 serverconfig. The public key is loaded from the provided path
2473 and saved as authentication data to void * pointer. Thus,
2474 changed the unsigned char *auth_data to void *auth_data;
2476 * Fixed SHUTDOWN command to send the reply before the server
2477 is shutdown. :) Affected file silcd/command.c.
2479 * Fixed fatal bug in CONNECT command. The hostname was invalid
2480 memory and server crashed. Affected file silcd/command.c.
2482 * Fixed fatal bug in CLOSE command. The server_entry became
2483 invalid but was referenced later in the command. Affected file
2486 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * Fixed fatal bug in failure packet handling. Server ignored
2489 the failure and thus crashed when it came.
2493 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2496 that the command may be executed only once in (about) 2 seconds.
2497 The old SILC_CF_LAG flag is same but allows command bursts up
2498 to five before limiting.
2500 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2501 server code. Various commands now includes the CF_LAG_STRICT
2502 flag to disallow any kind of miss-use of the command.
2504 * Fixed the silc_buffer_unformat to not to allocate any data
2505 if the length of the data is zero. It used to allocate the
2506 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2508 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Changed the format of AdminConnection configuration section
2511 in the server. Added username of the admin to the format.
2512 Affected files silcd/serverconfig.[ch].
2514 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2515 to return admin configuration data by host, username and/or
2518 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * Implemented WHOWAS command to the server. Added the functions:
2522 silc_server_command_whowas_parse,
2523 silc_server_command_whowas_send_reply,
2524 silc_server_command_whowas_from_client and
2525 silc_server_command_whowas_from_server
2527 * Added <Client ID> argument to the WHOWAS command reply. Updated
2528 the protocol specs accordingly.
2530 * Implemented WHOWAS command and command_reply to the client
2533 Implemented the WHOWAS printing on the user interface.
2535 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2537 * Added new argument to the WHOWAS command reply, the real name.
2538 It is an optional argument. Updated the protocol specs.
2540 * Added SilcIDCacheDestructor callback that is registered when
2541 the SilcIDCache is allocated. The callback is called when
2542 an cache entry in the ID Cache expires, or is purged from the
2543 cache. Added into lib/silccore/idcache.[ch].
2545 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2546 to destruct the client entries when the cache entry expires.
2547 Other ID Cache's in server and in the client library ignores
2550 * If the ID Cache entry's `expire' field is zero then the entry
2551 never expires. Added boolean `expire' argument to the
2552 silc_idcache_add function in the lib/silccore/idcache.[ch].
2553 If it is TRUE the default expiry value is used.
2555 * Added silc_server_free_client_data_timeout that is registered
2556 when client disconnects. By default for 5 minutes we preserve
2557 the client entry for history - for WHOWAS command.
2559 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Added support to the server to enforce that commands are not
2562 executed more than once in 2 seconds. If server receives
2563 commands from client more frequently, timeout is registered
2564 to process the commands. Affected file silcd/command.c.
2565 Added new function silc_server_command_process_timeout.
2567 * Changed NICK_NOTIFY handling in client library to check that
2568 if the client's nickname was changed, so there is no need to
2569 resolve anything from the server.
2571 * Removed error printing from the WHOIS and IDENTIFY commands.
2572 If error occurs then it is ignored silently in the client library.
2573 The application, however, may map the received error to
2574 human readable error string. The application currently maps
2575 the NO_SUCH_NICKNAME error to string.
2577 * Made the command status message public to the application. Moved
2578 them from lib/silcclient/command_reply.c to
2579 lib/silcclient/command_reply.h. The application can map the
2580 received command status to the string with the
2581 silc_client_command_status_message function.
2583 * Added check to the server to check that client's ID is same
2584 as the Source ID in the packet the client sent. They must
2587 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Added dist-bzip hook to the Makefile.am to make bzip2
2590 compressed distributions.
2592 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Server now enforces the maximum length for the nickname and
2595 the channel as protocol specification dictates. 128 bytes for
2596 nickname and 256 bytes for channel name.
2598 * Moved the WHOIS printing to the application. The client libary
2599 does not print out the WHOIS information anymore, the application
2600 must do it. Renamed silc_client_command_reply_whois_print to
2601 the silc_client_command_reply_whois_save.
2603 The client's idle time is also sent to the application now, and
2604 the idle is shown on screen.
2606 * Added silc_client_command_reply_identify_save to save the
2607 received IDENTIFY entries.
2609 * Do not check for channel private keys in message sending and
2610 reception if the channel does not have the PRIVKEY mode set.
2611 Affected file lib/silclient/client_channel.c.
2613 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2616 just surfaced after chaning the JOIN procedure.
2618 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Added silc_client_get_clients_by_list to get client entries
2621 from Client ID list, that is returned for example by JOIN
2622 and USERS command replies. The application should use this
2623 function for example when JOIN command reply is received to
2624 resolve the clients already on the channel (library does not
2625 do that anymore as USERS command reply is not used in the JOIN
2626 procedure anymore). Affected files lib/silcclient/silcapi.h and
2627 lib/silcclient/idlist.c.
2629 * JOIN command reply and USERS command reply returns now SilcBuffer
2630 pointers instead of unsigned char pointers when returning
2631 the client list and mode list.
2633 * Added <Client ID> argument to the JOIN command reply, mainly
2634 for the server to identify for which client the command was
2635 originally sent. Updated protocol specs accordingly.
2637 * Added SilcDlist private_key pointer to the SilcChannelEntry
2638 in the client to support the channel private keys. Affected
2639 file is lib/silcclient/idlist.h.
2641 * Added SilcChannelPrivateKey argument to the function
2642 silc_client_send_channel_message so that application can choose
2643 to use specific private ke if it wants to. If it is not provided,
2644 the normal channel key is used, unless private keys are set.
2645 In this case the first (key that was added first) is used
2646 as the encryption key.
2648 * Implemented the support for channel private key handling.
2649 Implemented the following functions:
2651 silc_client_add_channel_private_key,
2652 silc_client_del_channel_private_keys,
2653 silc_client_del_channel_private_key,
2654 silc_client_list_channel_private_keys and
2655 silc_client_free_channel_private_keys
2657 Affected file lib/silcclient/client_channel.c.
2659 * Added the support for the private keys in the channel message
2660 sending and encryption and in the message reception and
2661 decryption. Affected funtions are
2662 silc_client_send_channel_message and silc_client_channel_message.
2664 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Added SKE's key verify callback to the client library's
2667 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2669 * Removed the statement that server (or router) must send USERS
2670 command reply when joining to the channel so that the client
2671 knows who are on the channel. Instead, the client list and
2672 client's mode list is now sent in the JOIN command reply to the
2673 client who joined channel. This is better solution.
2675 * Added function silc_server_get_users_on_channel and function
2676 silc_server_save_users_on_channel to the silcd/server.[ch].
2678 * Removed function silc_server_command_send_users from the
2681 * Do not show topic on the client library anymore. The topic is
2682 sent in the command reply notify to the application and the
2683 application must show the topic now.
2685 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Added client searching by nickname hash into the IDENTIFY and
2688 WHOIS commands in the server as they were clearly missing from
2689 them. Affected file is silcd/command.c.
2691 * Fixed a bug in private message receiving in the client library.
2692 The remote ID was freed and it wasn't supposed, now it is
2695 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Minor fix to the channel payload; allocate the data area, as it
2698 needs to be of specific length.
2700 * If the key agreement port is zero then the operating
2701 system will define the bound port. Affected files are
2702 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2704 * Added new function silc_channel_payload_decrypt into the file
2705 lib/silccore/silcchannel.[ch].
2707 * Moved the channel message etc, check from silc_packet_decrypt
2708 to applications. The library calls now a generic
2709 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2710 when the packet is either normal or special. This was done to
2711 allow more wide range of checking that was not allowed when
2712 the code was in library. Now applications can do virtually any
2713 checks to the packet and return to the library the decision how
2714 the packet should be processed. Affected files are
2715 lib/silccore/silcpacket.[ch].
2717 Added silc_server_packet_decrypt_check to the server and
2718 silc_client_packet_decrypt_check to the client library.
2720 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2721 to send with specified source and destination information.
2723 * Channel message delivery between routers was broken after the
2724 channel key distribution was fixed earlier. The channel key
2725 was used be to distributed to other routers as well which is not
2726 allowed by the protocol. Now this is fixed and channel keys
2727 really are cell specific and the channel message delivery between
2728 routers comply with the protocol specification.
2730 * Fixed various commands in server to check also the global list
2731 for the channel entry and not just the local list. The affected
2732 file silcd/command.c.
2734 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Added assert()s to buffer formatting and unformatting routines
2737 to assert (if --enable-debug) when error occurs. Affected
2738 file: lib/silcutil/silcbuffmt.c.
2740 * Changed to auto-reconnect to check whether the remote host is
2741 router and register the re-connect timeout if it is. It used
2742 to check that whether we are normal server, but router must do
2743 auto-reconnect with another router as well. Affected file
2746 * Removed the [<key len>] option from CMODE command as the cipher
2747 name decides the key length, nowadays. See the defined ciphers
2748 from the protocol specification.
2750 * Added [<hmac>] option to the CMODE command to define the HMAC
2751 for the channel. Added SILC_CMODE_HMAC channel mode.
2753 * Added [<hmac>] option for the JOIN command so that user can
2754 select which HMAC is used to compute the MACs of the channel
2757 * Added Hmac field to the Channel Message Payload. The integrity
2758 of plaintext channel messages are now protected by computing
2759 MAC of the message and attaching the MAC to the payload. The
2760 MAC is encrypted. Now, it is clear that this causes some
2761 overhead to the size of the packet but rationale for this is that
2762 now the receiver can verify whether the channel message decrypted
2763 correctly and also when private keys are set for the channel the
2764 receiver can decrypt the packet with several keys and check from
2765 the MAC which key decrypted the message correctly.
2767 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2768 lib/silccrypt/silccipher.[ch].
2770 * Added silc_hash_len to return the digest length into the
2771 lib/silcrypt/silchash.[ch].
2773 * Rewrote parts of Silc Channel Payload interface in the
2774 lib/silccore/silcchannel.[ch]. The encode function now also
2775 encrypts the packet and parse function decrypts it.
2777 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Fixed a minor formatting bug in the SKE's key material processing.
2780 It actually might have processed the keys wrong way resulting
2783 * Redefined the mandatory HMAC algorithms and added new algorithms.
2784 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2785 and hmac-md5 truncated to 96 bits. The mandatory is now
2786 hmac-sha1-96. Rest are optional (including the one that used
2787 to be mandatory). Rationale for this is that the truncated HMAC
2788 length is sufficient from security point of view and can actually
2789 make the attack against the HMAC harder. Also, the truncated
2790 HMAC causes less overhead to the packets. See the RFC2104 for
2793 * Added new [hmac] configuration section. The SKE used to use
2794 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2795 is of course wrong. The official names that must be proposed in
2796 the SKE are the ones defined in the protocol specification
2797 (hmac-sha1-96 for example). The user can configure any hmac
2798 using any hash function configured in the [hash] section. At
2799 least, the mandatory must be configured.
2801 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2803 * Added HMAC list to the SKE proposal list. It has now both
2804 hash algorithm list and HMAC list. This makes the protocol
2805 incompatible with previous versions. The SKE now seems to work
2806 the way it is supposed to work, for the first time actually.
2808 * Defined plain Hash algorithms to the protocol specification.
2811 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Implemented support for key agreement packets into the server.
2814 Added functions silc_server_key_agreement and
2815 silc_server_send_key_agreement. Other than these functions,
2816 server has nothing to do with this packet.
2818 * Added support for private message key packets into the server.
2819 Added functions silc_server_private_message_key and
2820 silc_server_send_private_message_key.
2824 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2825 called in the protocol's final callback instead in the END
2826 protocol state. This makes a little more sense and in the same
2827 time in client we can use the same protocol routines for normal
2828 key exchange and to key agreement packet handling as well.
2830 * Added to both client's and server's KE protocol context the
2831 SilcSKEKeyMaterial pointer to save the key material. We will
2832 bring the key material to the protocol's final callback by doing
2833 this. The final callback must free the key material.
2835 * Added SKE's packet_send callback into client's KE protocol
2836 context so that the caller can choose what packet sending function
2837 is used. This way we can use different packet sending when
2838 doing normal SKE when doing key agreement packet handling (in
2839 the key agreement packet handling we do not want to encrypt
2842 * Implemented the responder side of the key agreement routines
2843 in the client. The client can now bind to specified port and
2844 accept incoming key negotiation. The key material is passed
2845 to the application after the protocol is over.
2847 * Implemented the processing of incoming Key Agreement packet
2848 in the client. Added function silc_client_key_agreement to
2851 * Implemented the intiator side of the key agreement routines
2852 in the client. The client can now initiate key agreement with
2853 another remote client. The key material is passed to the
2854 application after the protocol is over.
2856 * Created client_keyagr.c to include all the key agreement
2859 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2860 SILC_TASK_CALLBACK except that it is not static.
2862 * Created client_notify.c and moved the Notify packet handling
2863 from the client.[ch] into that file.
2865 * Created client_prvmsg.c and moved all private message and
2866 private message key routines from the client.[ch] into that file.
2868 * Create client_channel.c and moved all channel message and
2869 channel private key routines from the client.[ch] into that file.
2871 * Changed silc_client_get_client_by_id_resolve to resolve with
2872 WHOIS command instead of IDENTIFY command, in the file
2873 lib/silclient/idlist.c.
2875 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Implemented the SKE's responder side to the Client library.
2879 * When FAILURE is received to the protocol do not trust it
2880 blindly. Register a timeout to wait whether the remote closes
2881 the connection as it should do it, only after that process the
2882 actual failure. This was changed to both client and server.
2884 * Added client_internal.h to include some of the structures
2885 there instead of client.h in lib/silcclient/.
2887 * Added function silc_task_unregister_by_callback to unregister
2888 timeouts by the callback function.
2890 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Some "Incomplete WHOIS info" errors has been appearing on the
2893 log files. Took away the entry->userinfo check from WHOIS
2894 reply sending. The entry->userinfo is now " " if client did not
2895 provide one. I thought this was fixed earlier but something
2896 is wrong still. Let's see if the error still appears.
2898 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Fixed a minor bug in the login when the channel key is
2901 re-generated in the server. It used to generate the key in
2902 wrong order and thus caused problems in the channel traffic.
2904 * Fixed a minor bug in channel key distsribution after
2905 KICK command. The key was not sent to the router even though
2908 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added silc_ske_process_key_material_data as generic routine
2911 to process any key material as the SILC protocol dictates. The
2912 function is used by the actual SKE library but can be used by
2913 applications as well. This relates to the private message keys
2914 and the channel private keys since they must be processed the
2915 same way the normal SILC session keys. The protocol dictates
2916 this. Affected files: lib/silcske/silcske.[ch].
2918 Added also silc_ske_free_key_material to free the
2919 SilcSKEKeyMaterial structure.
2921 * Defined silc_cipher_set_key function to set the key for
2922 cipher without using the object's method function. The affected
2923 files: lib/silccrypt/silccipher.[ch].
2925 * Implemented silc silc_client_add_private_message_key,
2926 silc_client_add_private_message_key_ske,
2927 silc_client_del_private_message_key,
2928 silc_client_list_private_message_keys and
2929 silc_client_free_private_message_keys functions in the
2932 Added functions silc_client_send_private_message_key to send
2933 the Private Message Key payload and silc_client_private_message_key
2934 to handle incoming Private Message Key payload.
2936 * Added Cipher field to the Private Message Key payload to set
2937 the cipher to be used. If ignored, the default cipher defined
2938 in the SILC protocol (aes-256-cbc) is used.
2940 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Removed lib/silcclient/ops.h file.
2944 Redefined parts of the SILC Client Library API. Created new
2945 file silcapi.h that deprecates the ops.h file and defines the
2946 published Client Library API. Defined also private message key
2947 API and channel private key API into the file.
2949 This is the file that the application must include from the
2950 SILC Client Library. Other files need not be included by
2951 the application anymore.
2953 * Added new key_agreement client operation callback and also
2954 defined the Key Agreement library API for the application.
2956 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2959 is used by clients to request key negotiation between another
2960 client in the SILC network. If the negotiation is started it
2961 is performed using the SKE protocol. The result of the
2962 negotiation, the secret key material, can be used for example
2963 as private message key.
2965 Implemented the Key Agreement payload into the files
2966 lib/silccore/silauth.[ch].
2968 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Redefined ciphers for the SILC protocol. Added some new ciphers
2971 and defined the key lengths for the algorithms. Changed the
2972 code accordingly. The default key length is now 256 bits.
2974 * Fixed SKE key distribution function silc_ske_process_key_material
2975 when the key length is more than 128 bits. The default key
2976 length in SILC is now 256 bits.
2978 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2979 to indicate unsupported algorithm.
2981 * Renamed rijndael.c to aes.c and all functions as well.
2983 * Fixed a long standing channel key setting bug in client library.
2984 Weird that it has never surfaced before.
2986 * Fixed bug in channel deletion. If the entire channel is removed
2987 then it must also delete the references of the channel entry
2988 from the client's channel list as the client's channel entry and
2989 the channel's client entry share same memory.
2991 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Implemented CONNECT and SHUTDOWN commands in the client.
2995 * Implemented CLOSE command to the client.
2997 * Added the function silc_idlist_find_server_by_name into the
2998 files silcd/idlist.[ch].
3000 Added the function silc_idlist_find_server_by_conn into the
3001 files silcd/idlist.[ch].
3003 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * DIE command was renamed to SHUTDOWN. Updated the both code
3008 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3009 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3011 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3014 * Added function silc_server_create_connection function to create
3015 connection to remote router. My server implementation actually
3016 does not allow router to connect to normal server (it expects
3017 that normal server always initiates the connection to the router)
3018 so the CONNECT command is only good for connecting to another
3021 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3024 or some other client was kicked from the channel.
3026 Implemented the handling of the notify type to both client
3029 Implemented silc_server_send_notify_kicked to send the KICKED
3030 notify. It is used to send it to the server's primary router.
3032 * Implemented the KICK command into server and client.
3034 * Added `query' argument to the silc_idlist_get_client function
3035 to indicate whether to query the client from server or not if
3038 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3039 to indicate that the client is not channel founder.
3043 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Removed the rng context from SilcPacketContext structure and
3046 changed that the packet routine uses the Global RNG API.
3048 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added support for quit message that client can "leave" on the
3051 channel when it quits the SILC. It is ditributed inside the
3052 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3054 Added silc_server_free_client_data that will take the
3055 signoff message as argument.
3057 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3059 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Updated parts of the protocol specification to keep it up
3064 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3067 payloads in one packet.
3069 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3070 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3071 use now the new List flag.
3073 * Also deprecated the following packet types: REPLACE_ID,
3074 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3076 * Added list support for Notify packet in server.
3078 * Added silc_server_send_notify_channel_change to send the
3079 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3080 the silc_server_send_replace_id.
3082 * Added silc_server_send_notify_nick_change to send the
3083 NICK_CHANGE notify type. Deprecates the function
3084 silc_server_send_replace_id.
3086 * Added silc_server_send_notify_join to send the JOIN notify type.
3087 Deprecates the function silc_server_send_new_channel_user.
3089 * Added silc_server_send_notify_leave to send LEAVE notify type.
3090 Deprecates the function silc_server_send_remove_channel_user.
3092 * Added silc_server_send_notify_cmode and
3093 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3094 types. Deprecates the silc_server_send_set_mode function.
3096 * Added SERVER_SIGNOFF notify type to indicate that server has
3097 quit. This means that all clients on the channel from that
3098 server will drop. This can be also used when netsplit happens.
3100 Deprecated REMOVE_ID packet type since it is not needed anymore
3103 Added silc_server_send_notify_server_signoff to send the
3104 SERVER_SIGNOFF notify type. Deprecates the function
3105 silc_server_send_remove_id.
3107 Added also silc_server_send_notify_signoff to send the
3108 SIGNOFF notify type.
3110 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3111 SILC protocol from this day on. Changed the protocol
3112 specification as well.
3114 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3115 notify type. It is used between routers to notify about
3116 topic changes on a channel.
3118 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3121 * Partly updated the protocol specification to comply with the
3122 changes now made. It is still though a bit outdated.
3124 * The JOIN notify type now takes one extra argument <Channel ID>.
3125 The packet used to be destined to the channel but now the
3126 JOIN type may be sent as list thus it is impossible to
3127 destine it to any specific channel. By adding this argument
3128 it is again possible.
3130 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Added CREDITS file. The CHANGES and CREDITS file will appear
3133 in the distribution as well.
3135 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3138 types in the server's silcd/packet_receive.c.
3140 * Implemented CMODE and CUMODE to work in router environment.
3142 * Fixed minor encoding and decoding buglet from the
3143 lib/silccore/silcmode.c.
3145 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3148 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3150 * Changed all SilcConfigServer* and silc_config_server* to
3151 SilcServerConfig* and silc_server_config*, respectively.
3154 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Associated the ID (client or server ID) to the Authentication
3157 Payload to avoid any possibility of forging. Updated the
3158 protocol specification and the code accordingly.
3160 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * The RSA key length is now save to the RsaKey context in the
3163 key generation process in lib/silccrypt/rsa.c. The key length
3164 is now used to figure out the maximum size of the block allowed
3165 to be encrypted/signed.
3167 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3168 is equivalent to the silc_mp_mp2bin but does not allocate any
3171 * Changed silc_mp_mp2bin API to take length argument. If it is
3172 non-zero then the buffer is allocated that large. If zero, then
3173 the size is approximated using silc_mp_sizeinbase, which however
3176 * Created Global RNG API which is global RNG that application can
3177 initialize. After initializing, any routine anywhere in the
3178 code (including library) can use RNG without allocating a new
3179 RNG object. This was done to allow this sort of use of the
3180 RNG in code that has no chance to allocate RNG object. All
3181 applications currently allocate this and many routines in the
3182 library use this. Affected file lib/silccrypt/silcrng.[ch].
3184 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3185 it to use the Global RNG API.
3187 * Defined Authentication Payload into protocol specification that
3188 is used during SILC session to authenticate entities. It is
3189 used for example by client to authenticate itself to the server
3190 to obtain server operator privileges.
3192 Implemented this payload into the lib/silccore/silcauth.[ch].
3193 Implemented also routines for public key based authentication
3194 as the new protocol specification dictates.
3196 Moved definitions of different authentication methods from
3197 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3199 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3200 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3201 silc_pkcs_verify_with_hash functions into the file
3202 lib/silccrypt/silcpkcs.[ch].
3204 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * The client entry's userinfo pointer must be always valid.
3207 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3208 will fail since it requires the userinfo. Now, the userinfo
3209 is allocated as "" if actual userinfo does not exist. Actually,
3210 it must exist and it is totally Ok to drop client connections
3211 that does not announce the userinfo. However, we will make
3212 this workaround for now.
3214 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3215 to return the remote port by socket.
3217 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3220 SILC_SERVER_PENDING_EXEC and added an new macro
3221 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3222 data or when error occurs while processing the pending command.
3224 Added new argument `destructor' into silc_server_command_pending
3225 and to the SilcServerCommandPending object. This destructor is
3226 now called after calling the pending callback or if error occurs
3227 immediately. If error occurs the actual pending callback won't
3228 be called at all - only the destructor. The destructor may be
3229 NULL if destructor is not needed.
3231 All this applies for client library code as well. Similar
3232 changes were made there as well for the pending commands.
3234 In the client, the application must now allocate the
3235 SilcClientCommandContext with the silc_client_command_alloc
3238 * Added reference counter to the SilcServerCommandContext. Added
3239 function silc_server_command_alloc and silc_server_command_dup
3242 Same type of functions added to the client library for the same
3245 * Removed the cmd_ident from IDListData away since it is now
3246 global for all connections. It is the command identifier used
3247 in command sending and with pending commands. The affected file
3250 * Added reference counter to the SilcSocketConnection objecet to
3251 indicate the usage count of the object. The object won't be
3252 freed untill the reference counter hits zero. Currently only
3253 server uses this, and client ignores it. The client must be
3254 set to use this too later. The affected files are
3255 lib/silccore/silcsockconn.[ch]. Added also the function
3256 silc_socket_dup to increase the reference counter.
3258 This was mainly added because it is possible that the socket
3259 is removed underneath of pending command or other async
3260 operation. Now it won't be free'd and proper DISCONNECTING
3261 flags, etc. can be set to avoid sending data to connection that
3262 is not valid anymore.
3264 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3265 the connection. After that it sets SILC_SET_DISCONNECTED.
3266 It is, however, possible that the socket data is not still freed.
3267 The silc_server_packet_process now checks that data is not
3268 read or written to connection that is DISCONNECTED. The socket
3269 get's freed when the reference counter hits zero.
3271 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Changed the client operation API: channel_message operation's
3274 `sender' is now the client entry of the sender, not the nickname
3275 and the `channel' is the channel entry, not the channel name.
3277 In the private_message operation the `sender' is now also the
3278 client entry of the sender not the nickname.
3280 Affected file is lib/silcclient/ops.h and all applications
3281 using the client operations.
3283 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Moved the calling of ops->connect() from connect_to_server_final
3286 into receive_new_id functin since that is the point when the
3287 client is actually allowed to send traffic to network. The
3288 affected file is lib/silcclient/client.c.
3290 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3293 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3294 (if needs broadcasting) instead of broadcasting the packets one
3295 by one which would make a burst in the network traffic.
3297 * Added `broadcast' argument to the functions in silcd/server.[ch]
3298 silc_server_create_new_channel[_with_id] to indicate whether
3299 to send New Channel packet to primary router.
3301 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Added new function into the silcd/server.[ch] files:
3304 silc_server_create_new_channel_with_id to create new channel with
3305 already existing Channel ID.
3307 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3308 lib/silccore/silcpacket.h. This packet is used t send list of
3309 Set Mode payloads inside one packet. Server uses this to set
3310 the modes for the channels and clients on those channels, that it
3311 announced to the router when it connected to it. The protocol
3312 specification has been updated accordingly.
3314 * The silc_server_new_channel did not handle the packet coming
3315 from normal server as it normally does not send that. However,
3316 when it announces its channels it does send it. Implemented
3317 the support for that.
3319 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3320 into the file lib/silccore/id.h.
3322 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Fixed memory leaks in the functions silc_idlist_del_client,
3325 silc_idlist_del_channel and silc_idlist_del_server in the file
3326 silcd/idlist.c. All of those leaked like a sieve.
3328 * Fixed some small memory leaks in the client's function
3329 silc_client_notify_by_server.
3331 * Added functions into silcd/server.c: silc_server_announce_clients,
3332 silc_server_announce_channels and silc_server_announce_server.
3333 These functions are used by normal and router server to announce
3334 to its primary router about clients, channels and servers (when
3335 router) that we own. This is done after we've connected to the
3338 These functions effectively implements the following packet types:
3339 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3340 and SILC_PACKET_NEW_ID_LIST.
3342 * Added new functions into the silcd/packet_receive.[ch]:
3343 silc_server_new_id_list, silc_server_new_channel_list and
3344 silc_server_new_channel_user_list to handle the incoming
3345 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3347 * Added support of changing Channel ID in the function
3348 silc_server_replace_id. If the server that announces a channel
3349 to the router already exists in the router (with same name but
3350 with different Channel ID), router is responsible to send
3351 Replace ID packet to the server and force the server to change
3352 the Channel ID to the one router has.
3354 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3355 client that the Channel ID has been changed by the router. The
3356 normal server sends this to the client. Client must start using
3357 the new Channel ID as the channel's ID.
3359 Implemented handling of this new type into lib/silcclient/client.c
3360 into the function silc_client_notify_by_server.
3362 * Added new function silc_idlist_replace_channel_id into the files
3363 silcd/idlist.[ch] to replace the Channel ID.
3365 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Call silc_server_command_identify_check always when processing
3368 the IDENTIFY command in silcd/command.c
3370 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3373 send keepalive packets. The packet can be sent by clients,
3374 servers and routers.
3376 Added function silc_socket_set_heartbeat into the file
3377 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3378 If not set, the heartbeat is not performed. The actual
3379 heartbeat is implemented in the low level socket connection
3380 library. However, application is responsible of actually
3383 Added silc_server_send_heartbeat to send the actual heartbeat
3384 packet into silcd/packet_send.[ch]. Server now performs
3385 keepalive with all connections.
3387 * Added silc_task_get_first function into lib/silcutil/silctask.c
3388 to return the timeout task with shortest timeout. There was a bug
3389 in task unregistration that caused problems. TODO has been
3390 updated to include that task system must be rewritten.
3392 * The client library will now resolve the client information when
3393 receiving JOIN notify from server for client that we know but
3394 have incomplete information.
3396 * Rewrote parts of silc_server_remove_from_channels and
3397 silc_server_remove_from_one_channel as they did not remove the
3398 channel in some circumstances even though they should've.
3400 * Encryption problem encountered in server:
3402 The LEAVE command used to send the Channel Key packet to the
3403 router immediately after generating it. However, the code
3404 had earlier sent Remove Channel user packet but not immediately,
3405 ie. it was put to queue. The order of packets in the router
3406 was that Channel Key packet was first and Remove Channel User
3407 packet was second, even though they were encrypted in the
3408 reverse order. For this reason, MAC check failed. Now, this
3409 is fixed by not sending the Channel Key packet immediately but
3410 putting it to queue. However, this is more fundamental problem:
3411 packets that are in queue should actually not be encrypted
3412 because packets that are sent immediately gets encrypted
3413 actually with wrong IV (and thus MAC check fails). So, packets
3414 that are in queue should be encrypted when they are sent to
3415 the wire and not when they put to the queue.
3417 However, the problem is that the current system has not been
3418 designed to work that way. Instead, the packet is encrypted
3419 as soon as possible and left to the queue. The queue is then
3420 just purged into wire. There won't be any fixes for this
3421 any time soon. So, the current semantic for packet sending
3424 o If you send packet to remote host and do not force the send
3425 (the packet will be in queue) then all subsequent packets to the
3426 same remote host must also be put to the queue. Only after the
3427 queue has been purged is it safe again to force the packet
3430 o If you send all packets immediately then it safe to send
3431 any of subsequent packets through the queue, however, after
3432 the first packet is put to queue then any subsequent packets
3433 must also be put to the queue.
3435 Follow these rules and everything works fine.
3437 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Added new function silc_server_remove_clients_by_server to
3440 remove all client entries from ID list when the server connection
3441 is lost. In this case it is also important to invalidate all
3442 client entires as they hold the invalid server entry. This
3443 fixes fatal bug when server has lost connection and will reconnect
3446 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Made some sanity checks to silc_server_daemonise like to check
3449 whether the requested user and group actually exists.
3451 * Added sanity check to SKE's silc_ske_responder_finish to check
3452 that the public and private key actually is valid.
3454 * Invalidate the client's nickname when receiving Replace ID
3455 packet and the Client ID is being replaced. This means that the
3456 server will query the nickname if someone needs it (client)
3459 * Sort the ID Cache in client library when the ID Cache data
3460 has changed (needs sorting).
3462 * Do not allow for SILC client to create several connections to
3463 several servers. The client does not support windows right now
3464 and generating multiple connections causes weird behaviour.
3466 Irssi-silc client does support windows and can handle several
3467 connections without problems, see: www.irssi.org and SILC plugin.
3469 * Fixed some places where client was added to the IDList. The
3470 rule of thumb is following (in order to get everything right):
3471 If the client is directly connected local client then the
3472 `connection' argument must be set and `router' argument must be
3473 NULL to silc_idlist_add_client function. If the client is not
3474 directly connected client then the `router' argument must
3475 bet set and the `connection' argument must be NULL to the
3476 silc_idlist_add_client function.
3478 * The funtion silc_server_packet_send_local_channel actually did
3479 not check whether the client was locally connected or not. It
3480 does that now. Fixed a bug related to LEAVE command.
3482 * Fixed Remove Channel User payload parsing bug in server's
3483 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3485 * The server's silc_server_save_channel_key now checks also the
3486 global ID list for the channel as it might not be in the local
3487 list. Fixed a bug related to LEAVE command.
3489 * Is this the end of the [<unknown>] buglet that has been lurking
3490 around for a long time? A little for loop fix in server's
3491 silc_server_command_whois_parse that is used by both IDENTIFY
3492 and WHOIS command. At least, this was a clear bug and a cause
3493 of one type of [<unknown>] buglet.
3495 * WHOIS and IDENTIFY commands call the function
3496 silc_server_command_[whois/identify]_check function even if
3497 we are not router server.
3499 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Added --with-gmp configuration option. If set the GMP
3502 is always compiled in the SILC source tree. If not set then
3503 it is checked whether the system has the GMP3 installed. If
3504 it has then the GMP won't be compiled (the system's headers
3505 and library is used), if it doesn't have it then the GMP is
3506 compiled in the SILC source tree.
3508 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Changed RSA private exponent generation to what PKCS #1
3511 suggests. We try to find the smallest possible d by doing
3512 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3513 not security fix but optimization.
3515 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Added new config entry [Identity] to fork the server and run
3518 it as specific user and group. A patch from Bostik.
3520 * Imported Dotconf configuration library into lib/dotconf.
3521 This will be used to create the SILC configuration files later.
3522 It will appear in the distsribution after this commit.
3524 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * A big code auditing weekend happening. Auditing code for
3527 obvious mistakes, bugs and errors. Also, removing any code
3530 Removed files for being obsolete:
3532 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3533 inline in the file lib/silcutil/silcbuffer.h)
3535 o lib/silcutil/silcbufutil.c (the header has inline versions)
3537 Changed code to fix possible error conditions:
3539 o The buffer formatting routines now check that the destination
3540 buffer really has enough space to add the data. This applies for
3541 both buffer formatting and unformatting
3542 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3543 unformatting was changed to accomodate following rules:
3544 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3545 sent to the function while XXX_*STRING will not allocate or copy
3546 the data into the buffer. Instead it sets the pointer from the
3547 buffer into the pointer sent as argument (XXX_*STRING used to
3548 require that the pointer must be allocated already). This change
3549 makes this whole thing a bit more consistent and more optimized
3550 (note that the data returned in the unformatting with XXX_*STRING
3551 must not be freed now). The routines return now -1 on error.
3553 o Tried to find all code that use buffer_format and buffer_unformat
3554 and added return value checking to prevent formatting and
3555 especially unformatting errors and possible subsequent fatal
3558 o Changed ske->x and ske->KEY to mallocated pointers in
3559 lib/silcske/silcske.h. Fixed possible data and memory leak.
3561 o Added return value checking to all *_parse* functions. Fixed
3562 many memory leaks as well.
3564 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3565 so that buffer overflows would not happen. All code now also
3566 checks the return value as it can fail.
3568 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Added reconnection support to server if the normal server looses
3571 its connection to the router (for example if router is rebooted).
3572 The server performs normal reconnection strategy implemented
3573 to the server. Affected file silcd/server.c.
3575 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Added new packet type SILC_PACKET_SET_MODE that is used to
3578 distribute the information about changed modes (for clients,
3579 channels and clients channel modes) to all routers in the
3580 network. Updated the protocol specification accordingly.
3582 Added functions into silcd/packet_send.c and
3583 silcd/packet_receive.c: silc_server_send_set_mode,
3584 silc_server_set_mode.
3586 Added new files silcmode.[ch] into lib/silccore that implements
3587 the encoding and decoding of Set Mode Payload. Added new type
3588 SilcSetModePayload. Moved the definitions of different modes
3589 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3591 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Oops, a little mistake in server's connection authentication
3594 protocol. The protocol is not ended with FAILURE but with
3595 SUCCESS if the authentication is Ok. :) Affected file is
3598 * Implemented NICK_CHANGE notify handling in server in the file
3599 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3600 the local clients on the channel. After the changing nickname
3601 in router environment snhould work and the [<unknown>] nickname
3602 should appear no more.
3604 The silc_server_replace_id function that receives the Replace ID
3605 payload now sends the NICK_CHANGE notify type also in the file
3606 silcd/packet_receive.c
3608 * Changed WHOIS and IDENTIFY command to support the maximum amount
3609 of arguments defined in protocol specs (3328 arguments). This
3610 fixed a bug that caused problems when there were more than three
3613 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Added extra parameter, command identifier, to the
3616 silc_client_send_command so that explicit command identifier
3619 Changed that ID list routines uses specific command identifier
3620 when sending WHOIS/IDENTIFY requests to the server so that they
3621 can be identified when the reply comes back.
3623 Affected files lib/silcclient/command.[ch],
3624 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3626 * Added `sender' argument to silc_server_packet_send_to_channel
3627 to indicaet the sender who originally sent the packet to us
3628 that we are now re-sending. Ignored if NULL. Affected file
3629 silcd/packet_send.[ch].
3631 * Added some server statistics support in silcd/server_internal.h
3632 SilcServerStatistics structure and around the server code. Also
3633 send some nice statistics information when client is connecting
3636 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Fixed channel ID decoding in server's JOIN command reply in
3639 silcd/command_reply.c
3641 * Fixed braodcasting of replace ID payload to not to send it if
3642 we are standalone server in silcd/packet_receive.c.
3644 * Fixed all channel message sending routines to not to send
3645 packets to clients that has router set, since they are routed
3646 separately in the same function earlier. Affects file
3647 silcd/packet_send.c and all channel packet sending functions.
3649 * In USERS reply, res_argv[i] are not allocated, the table
3650 is allocated. Thus changed that free the table, not its
3653 * In server's whois_check and identify_check if the client is
3654 locally connected do not send any WHOIS commands - they are not
3657 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Fixed some minor bugs in client when sending WHOIS command. The
3660 arguments was in wrong order.
3662 * Removed statis function add_to_channel from server in
3663 silcd/command.c that was previously used with the joining but
3666 * Tested USERS command in router environment successfully with two
3667 routers, two servers and two clients.
3669 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * Reorganized the USERS command and command reply in client library
3672 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3673 When the command is given by user we register a pending command
3674 callback that will reprocess the command after the reply has been
3675 received from the server. When reprocessing the packet we then
3676 display the information. Thus, the USERS information is displayed
3677 now in the command callback instead of in the command reply
3678 callback. The processing of the command is same as previously
3679 when server has sent the command reply in the JOINing process.
3681 * Added to USERS command in silcd/command_reply.c to join the client,
3682 we didn't use to know about, to the channel after we've created
3683 a client entry for it. Also, for clienet we did know already still
3684 check whether it is on the channel or not and add it if not.
3686 * Removed silc_server_command_join_notify as the function and its
3689 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Changed the client's pending command handling to the same as the
3692 server's pending command handling. It is also now possible to
3693 execute command reply functions from other command reply
3694 function as the function callbacks for commands and command
3695 replies are one and same. The pending commands are not static
3696 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3697 in client connection context. Thus, pending commands are server
3698 connection specific as it is convenient.
3700 Changed the function silc_client_command_pending and
3701 silc_client_command_pending_del and added new function
3702 silc_client_command_pending_check. Removed the
3703 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3706 * Added cmd_ident, current command identifier, to the client
3707 connection context in lib/silcclient/client.h to keep track on
3708 command identifiers used in command sending. Client's command reply
3709 function handling now supports the mandatory command identifiers.
3711 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3712 funtions in client to fully support pending command callbacks.
3714 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3715 as one of the arguments to the application in the command reply
3718 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3719 before first releasing SILC but came back. Now it is removed again
3720 and should come back nomore. The FORWARDED flag was used only
3721 by the JOINing procedure by forwarding the command packet to router.
3722 Now, the JOINing procedure has been changed to more generic (due
3723 to various router environment issues) and FORWARDED is not needed
3724 anymore for anything. The protocol specification is yet to be
3727 Now, removed silc_server_packet_forward from server and the flag
3728 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3730 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Renamed NAMES command to USERS command. The NAMES was named that
3733 due to historical reasons. Now it is renamed. Also, rewrote
3734 parts of the USERS command. The nickname list is not sent anymore
3735 by the server. Only Client ID and mode lists are sent in the USERS
3736 command. Changed this also to the protocol specification.
3738 The client now resolves the names and stuff after it receives
3739 the USERS list from the server when joining to the channel.
3741 * WHOIS and IDENTIFY commands has been changed to support multiple
3742 Client ID's per command. One can now search for multiple users
3743 in the network by sending only one WHOIS or IDENTIFY command.
3744 Changed the code and the protocol specifications.
3746 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3747 uses silc_server_command_whois_parse to parse the request. */
3749 * If normal server, do not parse the WHOIS and IDENTIFY requests
3750 before sending it to the router. Saves some time.
3752 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Fixed JOIN command on client library. Wrong number of arguments
3755 used to crash the client.
3757 * Added silc_server_channel_has_global function to check whether
3758 channel has global users or not.
3760 * Added silc_server_channel_has_local function to check whether channel
3761 has locally connected clients on the channel.
3763 * The silc_server_remove_from_one_channel now checks whether the
3764 channel has global users or not after given client was removed from
3765 the channel. It also checks whether the channel has local clients
3766 on the channel anymore. If it does not have then the channel entry
3767 is removed as it is not needed anymore.
3769 * The silc_server_notify now checks on JOIN notify whether the joining
3770 client is one of locally connected or global. If it is global then
3771 the channel has now global users on the channel and that is marked
3772 to the channel entry. Also, it now saves the global client to
3773 global list who is joining and JOINs it to the channel. This is
3774 for normal server, that is.
3776 Changed silc_server_send_notify_on_channel,
3777 silc_server_packet_relay_to_channel and
3778 silc_server_packet_send_to_channel check if we are normal server
3779 and client has router set (ie. global client) do not send the
3780 message to that client, as it is already routed to our router.
3782 * Implemented LEAVE notify type handling in silc_server_notify
3785 * Tested LEAVE command in router environment successfully. Tested
3786 with two routers, two servers and two clients.
3790 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3792 * Implemented SIGNOFF notify type handling in silc_server_notify
3795 * silc_server_remove_id now removes the client entry from all channels
3796 it has joined and thusly sends SIGNOFF notify type.
3798 * Rewrote the NAMES list generation in server by removing two excess
3799 loops. The lists are created now inside one loop.
3801 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * silc_server_remove_channel_user checks now also global list
3804 for channel and client.
3806 * silc_server_new_channel_user checks now both local and global
3807 list for channel and client. Fixed a bug in client id decoding.
3808 Used to decode wrong buffer.
3810 * silc_server_channel_message checks now both local and global
3811 list for channel entry.
3813 * Tested channel joining (hence JOIN) in router environment
3814 successfully. Tested with two routers, two servers and two
3817 * Tested channel message sending in router environment successfully.
3819 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added silc_server_save_channel_key into server.[ch] to save the
3822 received channel key in Channel Key payload processing. It is
3823 also used in JOIN command reply handling.
3825 Equivalent function silc_client_save_channel_key added into
3826 client.[ch] into client library.
3828 * Changed JOIN command reply to send information whether the channel
3829 was created or not (is existing already) and the channel key
3830 payload. Changed protocol specs accordingly.
3832 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3833 the request was sent by ID and not by nickname. Crashed on
3836 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3839 now correctly save the received data.
3841 * silc_server_free_sock_user_data now notifies routers in the
3842 network about entities leaving the network.
3844 At the same time implemented functions silc_server_remove_id
3845 and silc_server_send_remove_id to receive and send REMOVE_ID
3846 packets. The packet is used to notify routers in the network
3847 about leaving entities. The ID removed will become invalid in
3850 * Added function silc_idlist_del_server into server. Removes and
3851 free's server entry from ID list.
3853 * silc_server_private_message function now checks, if we are router,
3854 that the destination ID really is valid ID, naturally.
3856 * In router when NEW_ID packet is received (for new client) the
3857 hash of the Client ID is saved in the ID Cache but the
3858 client->nickname is set to NULL, instead of putting the hash
3861 IDENTIFY command now also checks that client->nickname must be
3862 valid. If it is not if will request the data from the server who
3863 owns the client. Added new function
3864 silc_server_command_identify_check.
3866 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3867 to set the command to already allocated Command Payload.
3869 * Tested private message sending in router environment with two
3870 routers, two servers and two clients. Fixed minor bugs and now
3873 * Fixed segfault from client's NAMES command. Used to crash if
3876 * Forwarded packets must not be routed even if it is not destined
3877 to the receiver. Changed server code comply with this.
3879 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Added `require_reverse_mapping' boolean value to ServerParams
3882 structure. If TRUE (not default) the server will require that
3883 the connecting host has fully qualified domain name.
3885 If the reverse mapping is not required and hostname could not be
3886 found the IP address is used as hostname.
3888 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Implemented version string checking to both client and server.
3891 The check is incomplete currently due to the abnormal version
3892 strings used in development version of SILC.
3894 * Changed all command functions in server to use the new
3897 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Changed char *data to unsigned char *data in ID Cache system to
3900 support binary data as ID Cache data. Changed code to support
3901 binary data in lib/silccore/idcache.c.
3903 * Renamed silc_server_packet_relay_command_reply to
3904 silc_server_command_reply as it is normal packet receiving
3905 function. Rewrote the function to accept command replys for
3906 servers and not only for clients.
3908 * Mark remote router always as registered server if we are connecting
3909 to it. Otherwise, commands sent by the router to us are ignored.
3911 * All ID List find routines now returns the ID Cache Entry pointer
3912 as well if requested.
3914 * WHOIS command works now in router environment, tested with two
3915 routers, two servers and two clients.
3917 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3918 in router environment (as it is almost equivalent to WHOIS) but
3919 hasn't been tested thoroughly. Added new functions:
3921 silc_server_command_identify_parse
3922 silc_server_command_identify_send_reply
3923 silc_server_command_identify_from_client
3924 silc_server_command_identify_from_server
3926 * Disabled route cache adding because adding two different ID's with
3927 same IP replaces the old cache entry thus giving wrong route.
3928 The entry->router->connection is always the fastest route anyway
3929 so route cache may not be needed. Of course, new routes maybe
3930 established after receiving the ID when the entry->router->connection
3931 might not be anymore the most optimal.
3933 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Add route cache for received ID for fast routing.
3937 * Added silc_server_packet_route to route received packet on router
3938 that is not destined to us.
3940 * Renamed silc_server_get_route to silc_server_route_get.
3942 * Added id_string and id_string_len fields into SilcServer to
3943 include encoded ServerID for fast comparing without excess
3944 encoding of the ID's.
3946 * Cleaned up WHOIS command on server side. Added following static
3949 silc_server_command_whois_parse
3950 silc_server_command_whois_check
3951 silc_server_command_whois_send_reply
3952 silc_server_command_whois_from_client
3953 silc_server_command_whois_from_server
3955 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3956 arguments in command replies. All command functions should be
3957 updated to use this macro.
3959 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Minor typo fixes on command reply handling on server.
3963 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Added silc_server_command_add_to_channel internal routine to add
3966 the client to the channel after router has created the channel and
3967 sent command reply to the server.
3969 * Added generic silc_server_send_command to send any command from
3972 * Use static buffer with ID rendering instead of duplicating data.
3974 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Fixed a channel user mode bug when joining to a channel server gave
3977 everybody channel founder rights, oops.
3979 * We mark ourselves as the router of the incoming server connection
3980 if we are router ourselves. This way we can check in some packet
3981 sending functions whether it is locally connected server. For
3982 incoming router connections we put NULL.
3984 * For router sending packets locally means now always sending the
3985 packet cell wide; to local clients and local servers. For normal
3986 server sending packet locally means sending it to only local
3989 * Fixed the JOIN command to really work in router environment. If the
3990 channel is created it is always created by the router. Router is
3991 also responsible of making the initial joining to the channel,
3992 sending JOIN notify to the sending server and distributing
3993 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3994 does not exist server doesn't do anything else but forward the
3995 command to the router which performs everything.
3997 * Added silc_server_send_channel_key function to send the Channel Key
4000 * Added silc_server_create_channel_key to create new channel key. The
4001 channel key is now re-generated everytime someone joins or leaves
4002 a channel, as protocol dictates. Note: channel->key_len is the
4005 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4008 packet_receive.[ch] to separate packet sending and receiving
4009 routines. The server.[ch] now includes everything else including
4010 actual packet processing (writing and reading data) and other
4013 Renamed silc_server_private_message_send_internal to
4014 silc_server_send_private_message. The routine is still though
4015 used only to relay private messages as server does not send
4016 private messages itself.
4018 Renamed silc_server_new_channel to silc_server_create_new_channel
4019 and added new function sicl_server_new_channel that handles the
4020 incoming New Channel packet. Added also new sending function
4021 silc_server_send_new_channel to send New Channel Payload.
4023 * Added new function silc_server_notify to process incoming notify
4024 packet to the server/router. Server may then relay the notify
4025 to clients if needed.
4027 * Added new function silc_server_new_channel_user to process incoming
4028 New Channel User packet. Router will redistribute the packet and
4029 send JOIN notify to its local clients and locally connected servers
4030 if needed. Normal server will send JOIN notify to its local client
4031 on same channel when received this packet. Added also corresponding
4032 sending function silc_server_send_new_channel_user to sent the
4035 * Added boolean route argument to send_notif_to_channel and
4036 packet_send_to_channel functions to attempt to route the packet
4037 if it is TRUE and send only locally if it is FALSE.
4039 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * silc_server_replace_id now broadcasts the received replace ID
4042 packet if it is not broadcast packet already. The router must
4043 broadcast to inform other routers about changed ID.
4045 * Added backpointer to server's router into SilcServer context in
4046 silcd/server_internal.h.
4048 * Fixed silc_server_packet_broadcast to send correct broadcast
4051 * The channel key is now distributed to the local client as soon
4052 as it is received from the router (in router environment) so that
4053 no other packet may be sent for the channel until client has
4056 * silc_server_remove_channel_user now broadcasts the received
4057 Remove Channel User packet if it is not broadcast packet already.
4058 The router must broadcast to inform other routers about removed
4061 * Added users field into SilcPacketContext that is a reference count
4062 of the context. One can increase the reference count by calling
4063 silc_packet_context_dup which is now changed to just increase the
4064 reference count instead of duplicating the data. The reference
4065 count is decresed by calling silc_packet_context_free that will
4066 free the data after the reference count hits zero.
4068 For now on the packet context and everything allocated into it
4069 (including the raw packet from network) must be freed by calling
4070 the new silc_packet_context_free function. Added also new function
4071 silc_packet_context_alloc that must be used now to allocate the
4072 context. This also means that if a routine is asynchronous from
4073 silc_[client/server]_packet_parse_type the packet context must
4074 be duplicated by calling silc_packet_context_dup. Otherwise it
4075 gets free'd after silc_[client/server]_packet_parse_type returns.
4076 Also, one must remember that if packet is duplicated then its
4077 reference count must be decresed by calling the free function as
4078 many times as it was duplicated.
4080 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4081 from both client and server.
4083 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Made joining to a channel working in router environment.
4087 * Cleaned up JOIN command on server side and create function
4088 silc_server_command_join_channel internal routine to make the
4091 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Changed silc_command_pending list to SilcDList. Also, added
4094 `ident' field to SilcServerCommandPending structure to identify
4095 the reply and to call correct callback.
4097 Added silc_server_command_pending_check function to replace the
4098 corresnponding macro. The silc_command_pending list is not
4101 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4102 to set identifier to previously allocated Command Payload. It
4103 is used to set identifier for command when resending Command
4106 * Added silc_command_payload_encode_payload to encode Command
4107 Payload buffer from SilcCommandPayload structure.
4109 * Added silc_argument_payload_encode_payload to encode Argument
4110 payload buffer from SilcArgumentPayload structure.
4112 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Changed WHOIS command to support router connection on server side.
4115 The whois request is always sent to router unless the server is
4116 standalone server. After server has received the reply from the
4117 router will it send the reply to the client.
4119 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4120 broadcast received broadcast packet. The function is used only
4121 by router. The broadcast packet is always sent to the router's
4124 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4125 render given ID to printable string, for log files for example.
4127 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Made basic router to router connections working. At least they
4130 can now connect to each other but nothing really works the way
4131 they are supposed - yet.
4133 * Added new initiator token to RouterConnection configuration
4134 file in silcd/serverconfig.[ch]. It is used to tell whether we
4135 are the initiator to the remote router or whether we'll expect
4136 the other end to connect.
4138 * Moved registering of listener task to silc_server_init, hence
4139 the server starts listenning as soon as it is run, even if it
4140 does not have connections to other routers. Let's see how well
4143 * Changed default connection retry timeouts for more suitable in
4146 * Removed cipher and such arguments from silc_idlist_add_client
4147 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4148 Added new function silc_idlist_add_data to add the keys and stuff
4151 * Added SilcIDListData structure and added it to SilcClientEntry
4152 and SilcServerEntry as their first field in the structure. This
4153 way we can explicitly cast the ID entries to the SilcIDListData
4154 structure and get common data for the entries. In past, we had
4155 to first check what type of connection it is and then cast it to
4156 correct ID entry type. Now, we can directly cast the opaque
4157 pointer to the SilcIDListData (no matter what ID entry it actually
4158 is) and get the data needed.
4160 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4163 in some circumstances even if threre were timeout tasks, though not
4164 IO tasks, but tasks anyway. Now fixed.
4166 * Defined SilcServerConnection structure to hold connection specific
4167 stuff about directly connected servers and routers. The definition
4168 is currently in silcd/server_internal.h. I thought about having
4169 a bit more important role fro this struct but for now it is used
4170 only when connecting to other server (or router actually).
4172 * Added connecting retry support in server when connecting to
4173 router(s). The retry feature implement exponential backoff
4174 algorithm. Also, added SilcServerParams structure to hold default
4175 parameters for server. For now, it include these retry settings
4176 and are hard coded. After server is moded to be as Silc Server
4177 Library this structure will be more important.
4179 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Changed client librarys channel->clients table to SilcList and
4182 changed code accordingly.
4184 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Changed client's channel table to SilcList and changed code
4187 accordingly. Also changed SilcChannelClientEntry to include back-
4188 pointer to the channel so that client entry can use that structure
4189 as list as well and we have fast cross-reference to the channel.
4190 This change dramatically decreased the complexity of channel
4191 handling with client entry and vice versa (removed one extra
4192 loop when searching for channel entry from many functions).
4194 * Changed server->sim from table to SilcDList and changed code
4197 * NAMES command can now be used from user interface. It will show
4198 the user list on the channel, neatly.
4200 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4201 Code now saves realname of the user if it becomes available.
4203 * Renamed configure.in to configure.in.pre and made ./prepare
4204 script to automatically add correct version string to
4205 configure.in which it creates from configure.in.pre.
4207 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * NAMES command reply now shows users mode with the nickname when
4212 * Moved silc_client_ch[u]mode[_char] functions from
4213 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4214 place sucks, they are utility functions and should be in some
4217 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4219 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4222 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Added TRQ (efficient deque and list library) into lib/trq. This is
4227 a very good list library that is currently used in the SILC. Defined
4228 SilcList API over the library because I didn't like the API very
4229 much. See lib/trq/silclist.h for the API and examples of how to
4230 use the API. Fixed various places in the code to use the new
4231 SilcList API. The SilcList is meant for lists that has a structure
4232 already defined as a list. It is not suitable to add just some
4233 context to the list (in TRQ, the context is the list actually).
4235 So, I defined SilcDList that can be used for the purpose where
4236 predefined list structure does not exit. This can be used as
4237 such list. Now some context just can be added to the SilcDList.
4238 Currently this list is not used in the SILC just yet, though there
4239 are a lot places where this can replace dynamically allocated
4240 tables and I will fix these places, later, to use SilcDList.
4241 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4242 and use TRQ internally).
4244 Also fixed some annoying warning messages that the original TRQ
4245 code generated. Also minor changes to TRQ's Makefile.in.
4247 * Added support for querying by Client ID to both WHOIS and
4248 IDENTIFY commands into server, as required by the protocol.
4250 * Removed method function pointers from SilcBuffer structure. They
4251 weren't used to anything and just increased the context size for
4252 no good reason. This change also made silc_buffer_alloc and
4253 silc_buffer_free functions inline functions.
4255 * Disabled command flooding detection support until it's fixed so
4256 that it accepts commands in but does not execute them more than once
4259 * Added silc_net_localhost(), to return local hostname, into
4260 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4261 that must be initialized before calling silc_client_init.
4263 * Added new function: silc_server_send_notify_on_channels to send
4264 notify messages to all channels client has joined. It is assured
4265 that the message is sent only once per client.
4267 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4268 lib/silcutil/silcutil.[ch] as silc_format function. The new
4269 function is generic and is used by server as well, not only by
4270 the logging routines.
4272 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4273 the provided version string was not acceptable. Added new function:
4274 silc_ske_check_version into lib/silcske/silcske.h. The function
4275 must be implemented by the application (client or server) and it
4276 does not reside in the SKE library. The function checks the version
4277 string remote end sent.
4279 * Added back pointers (to opaque context and to SilcSocketConnection)
4280 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4282 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4283 duplicate packet context structure.
4285 * Changed `notify' client operation to send same arguments as client
4286 receives from server except for ID's. ID's are mapped to correct
4287 ID entry and that is returned. Also, if channel entry is not sent
4288 by server but the notify is for channel the channel entry is sent
4289 to application (otherwise application doesn't know that it is for
4290 channel (library gets it from packet's Destination ID)).
4292 * Added silc_client_remove_from_channels into client library to
4293 remove a client from all channels it has joined to. Used when
4294 received SIGNOFF notify from server. Added also new function
4295 silc_client_replace_from_channels to replace old ID entry with
4296 new ID entry on all channels. Used when received NICK_CHANGE
4299 * Fixed ID Cache list handling in silc_idlist_get_client in
4300 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4301 to get (or query) client by ID.
4303 * Updated TODO list.
4305 * Added connection authentication status message defined by the
4306 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4307 support for these into the code in client and server side.
4309 * Added generic function silc_client_send_command to send any command
4310 with variable argument list. Application should use this function
4311 to send commands if the command functions provided by the library
4312 does not suite for the application's user interface needs.
4314 * Added new `failure' client operation. Application is notified about
4315 received failure packet if client is executing a protocol. In this
4316 case the protocol's execution has failed.
4318 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4319 is required by the protocol.
4321 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4322 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4325 * Added status flag to SilcSKE object to indicate realtime status
4326 of the SKE protocol.
4328 * Application receives now exactly same command reply arguments as
4329 the library receives from server. However, if ID is received the
4330 corresponding ID entry is returned to the application (eg. Client
4331 ID is mapped to correct SilcClientEntry entry and that is returned).
4332 Changed command_reply client operation due to this change.
4334 * Changed all ID's in commands and in command replys as ID Payloads.
4335 Change affected both client and server side codes.
4337 All ID's sent in SILC network (with execption of ID's in SILC
4338 Packet header) are sent in ID Payload to support variable length
4341 * Server now notifies nick changes and notifies all clients on
4342 the channels about the new nickname (about the new Client ID,
4345 * Implemented CMODE command to change channel modes. Supports all
4346 channel modes defined by the protocol specs except ban and invite
4347 lists. (Also, private channel key mode is supported but support for
4348 setting private channel key in client is missing, thus, this mode
4349 has no effect on client side (except that server requires that the
4350 client uses private channel key and normal channel traffic does not
4353 Also, invite mode works per se, but INVITE command does not work
4354 yet correctly, so you can set channel as invite only channel but
4355 inviting clients to the channel does not work (it is yet to be
4356 thought what's the best way to do it).
4358 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4359 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4360 Implemented CUMODE command to change user's mode on the channel.
4361 Supports all modes defined by the protocol specs.
4363 * Added NAMES command reply to return users modes on the channel.
4365 * Removed unnecessary and slow ciphers from lib/silccrypt.
4367 * Set SO_KEEPALIVE option to connection sockets by default.
4369 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4371 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4372 redefined the Notify Payload into protocol specs.
4374 * Added silc_id_payload_parse_id to get ID directly from raw
4377 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4380 accept searching by Client ID as well.
4382 * Added support for LEAVE and SIGNOFF notify types in client library.
4384 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4385 to parse ID Payload from raw data.
4387 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Added flags parameter into silc_ske_assemble_security_properties
4390 function in lib/silcske/silcske.[ch].
4392 * Changed notify client operation to fit better for notify messages
4393 sent by server. The notify payload received from server is now
4394 passed to the application (after parsing it to SilcNotifyPayload).
4395 It is application's responsibility to retrieve the arguments
4396 from the payload and show the message the way it wants. The message
4397 sent by server is implementation specific.
4399 * Changed public keys to comply with the protocol specification.
4400 Old public keys are not supported anymore and are not compatible.
4402 * Removed nickname from Channel Payload as the latest draft removed
4403 it. The client must resolve the nickname from the NAMES command
4404 reply received when it joined the channel.
4406 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4408 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Fixed some errors in protocol specification drafts.
4412 * Created lib/silccore/silcnotify.c to implement Notify Payload
4413 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4414 generic payloads described by protocol specifications. The file
4415 includes implementations for ID Payload and Argument Payload.
4417 * Changed Command Payload implementation to use the new Argument
4418 Payload. Changed command_xxxx_payload to command_payload_xxxx
4419 to comply with SILC coding conventions.
4421 * Added suppport for Argument Payload handling in Notify Payload
4422 implementation as protocol requires it. Added the new support
4423 into server and client lib as well.
4425 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added support for multiple nicknames on same channel. [n] is
4428 added locally to the nickname if there are more than one same
4429 nicknames on the channel.
4431 * Server now sends all nicknames that matched WHOIS request.
4432 Client also shows the list received from server.
4434 * Added TOPIC command to client side. User can now set and show
4435 current topic on channel.
4437 * Added MOTD command to client and server. Also, server sends the
4438 motd when client connects to the server.
4440 * Changed version strings to comply ISO 8601.
4442 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Fixed protocol error handling in client library. It should now
4445 cope even if the SKE fails for some reason.
4447 * Made new protocol specification drafts for submitting to IETF.
4449 * Implemented TOPIC command to server in silcd/command.c.
4451 * Added two new notify types into lib/silccore/silcnotify.h:
4452 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4453 notify nickname change and topic setting/change on a channel.
4455 * API change of command_reply operation in client library. The
4456 application gets now the status type received from server as well.
4458 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4462 * Cras fixed and optimized the packet handling even further and
4463 it should work now. Minor change to the prototype of function
4464 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4466 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Added new function into lib/silcutil/silcschedule.[ch]:
4469 silc_schedule_with_fd to select() a specified fd. The function
4470 returns after timeout expires or data arrives or goes. The
4471 function is used by packet routines to wait that all data is
4472 received from network.
4474 * Fixed data reading from network in lib/silccore/silcpacket.c.
4475 The code now assures that all data is read from the fd and then
4476 continues packet processing. This was a bug fix since the code
4477 used to drop some data in some circumstances.
4479 * Added new function into lib/silcclient/client.[ch]:
4480 silc_client_start_key_exchange to start key exchange after
4481 connection has been established to server. The code internally
4482 now uses this funtion but its main purpose was to provide it
4483 for applications that perform their own connecting. After
4484 application has created a connection it merely calls this
4485 function to start the key exchange between client and server.
4486 The library takes care of everything else after that.
4488 Updated also lib/silcclient/README to explain the usage of
4491 * Do not send to application information that connection has
4492 been established. Application gets notified it by connect
4495 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Applied cras's patch to add silc_schedule_one function. The
4498 function runs scheduler once and returns.
4500 * Fixed the scheduler after cras messed it up. The timeout
4501 handling works now as it's supposed to work.
4503 * Added into lib/silccore/ silcnotify.h to include notify
4504 message types support. Changed silc_server_send_notify*
4505 functions, in server.[ch], to support those new notify types.
4506 Added the support for the notify types into client library,
4507 as well. Added new notify client operation into ops.h in
4510 * Changed silc_server_packet_send_to_channel to send normal
4511 packets instead of just channel message packets. The function
4512 is now used to send the notify packets to channels. It is not
4513 used to send channel message packets anymore, as server never
4516 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4517 va_arg()s as it seems to require it nowadays. I guess, if SILC
4518 is compiled with older va_arg() the new code should work anyway.
4520 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Splitted core library. Core library (lib/silccore) includes
4523 now only SILC protocol specific core (and common) components.
4524 Created new utility library (lib/silcutil) that includes more
4525 generic purpose stuff. The stuff for util library was taken
4526 from the old core library. This was minor and easy split.
4528 * Created SILC Client Library (lib/silcclient) that includes
4529 implementation of the SILC client without user interface. This
4530 was major move from silc/ directory. The code has been changed
4531 so that it is transparent towards the user interface. The
4532 silc/ directory includes now the same user interface as before
4533 and it uses the new client library. Read lib/silcclient/README.
4534 Basicly, the client library performs everything else related
4535 to SILC except user interface handling. Also, configuration
4536 files are considered to be part of user interface and library
4537 does not handle them.
4539 This change also changed a lot of structures, function naming etc.
4540 Most important change was that SilcClientWindow object was
4541 renamed to SilcClientConnection in the client library. Created
4542 also new file lib/silcclient/ops.h. Also added new files
4543 silc/local_command.[ch] and silc/client_ops.[ch].
4545 All these changes were made to make it easier for user interface
4546 designers to create what ever user interface for the SILC client
4549 It is also expected that the server will be moved to lib
4550 directory as well and SILC Server Library will be created;
4551 sometimes in the future.
4553 * Removed Local commands from lib/silccore/silccommand.h as
4554 they are application specific and new client library does not
4555 handle any of those anymore.
4557 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4558 old client implementation in silc/.
4560 * Added support for callback functions in SILC_LOG_* macros.
4561 Application can now set its own callbacks that will be called
4562 instead of using the default functions that will always print
4563 the debug messages to stderr (or stdout). Also, debugging can
4564 now be disabled by setting silc_debug to FALSE and re-enabled by
4565 setting it to TRUE. Note, that logging will still work even
4566 if debugging is disabled.
4568 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4569 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4570 silc_log_reset_debug_callbacks.
4572 * To enable debugging in silc client one must give now -d
4573 option on command line.
4575 * Changed silc_schedule_init to automatically allocate task queues
4576 if they are not allocated before calling it.
4578 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Added GMP 3.1 into math library.
4582 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4585 a channel in SILC network. The packet is used by servers and
4586 routers to notify other routers that user has left a channel.
4587 This little feature was missing until now. Added the feature
4588 to protocol specification as well.
4590 Added functions: silc_server_send_remove_channel_user and
4591 silc_server_remove_channel_user into server.[ch].
4593 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4594 lib/silccore/silcpacket.h. However, they are not implemented
4597 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Fixed joining to a channel and sending channel messages
4600 between server and router. The channel message sending should
4601 now work inside a cell.
4603 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Fixed the private message sending between server and router.
4606 The private message sending should now work inside a cell.
4608 * Added silc_server_replace_id into server.[ch] to replace
4609 existing ID in the SILC network.
4611 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4612 and silc_idlist_replace_server_id into idlist.[ch] in server.
4614 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Fixed the server to server connections. Server can again now
4617 connect to router. Router to router connections probably does
4620 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added dynamic protocol registering support. Now protocols can
4623 registered and unregistered on the fly. Patch by cras.
4625 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Added lib/contrib directory to hold routines that some platforms
4628 don't have but are needed by SILC.
4630 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4631 into lin/contrib to provide getopt() and getopt_long() for
4632 those who don't have it.
4634 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added AWAY command to client. When away message is set and
4637 client receives a private message packet the client automatically
4638 replies to the sender with the away message.
4640 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4641 bug seemed to be the cause of recent problems when compiling
4644 * Added version detection support to SKE protocol specification
4645 and added the new changes to the SKE implementation as well.
4646 There were other minor changes in the SKE protocol as well.
4648 Many changes in lib/silcske/silcske.[ch] and in
4649 lib/silcske/payload.[ch].
4651 * Added ^U functionality, clear input line. Patch from cras.
4653 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Mainly small bugfixes on core library. Fixed some debugging
4656 logging and buffer overflow in silclog.c.
4658 * Updated config.sub and config.guess on the distribution tree.
4660 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Added command lagging support in server. Client may execute
4663 commands now only once in two seconds.
4665 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Optimized packet reception. MAC computation and checking is now
4668 also more optimized. A lot previously duplicated code is now
4669 used as generic by both client and server.
4671 * Fixed key pair generation in clientutil.c
4673 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Added into lib/silccore/silcbufutil.[ch] new function;
4676 silc_buffer_realloc.
4678 * Moved generic packet sending/encryption functions to
4679 lib/silccore/silcpacket.[ch] from client and server. Some
4680 rewriting of the functions.
4682 * Moved all generic packet reception/decryption functions to
4683 lib/silccore/silcpacket.[ch] from client and server. The
4684 packet processing is now much cleaner in both client and server.
4685 These were major changes in both client and server.
4687 * Created many common functions in server to do packet sending.
4688 Previously code were duplicated a lot, this has been removed
4691 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Rewrote major parts of the ID cache system. Don't know
4694 whether it is better now or not but at least the API is more
4697 * Major rewrite on ID cache stuff on client because of the ID
4698 cache API changes. Added idlist.c to client.
4700 * Also major rewrite on ID cache stuff on server as well.
4701 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4702 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4703 in hand, instead they are all put into the ID cache system now.
4704 All server_idlist_* routines uses ID cache now instead of
4705 traversing its own lists (those lists does not exist anymore).
4706 SilcIDList though still exists. Also, SilcXXXEntry's are
4709 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Finally made the SKE implementation compliant to the protocol
4712 specification. All mp integers are now binary encoded as
4713 opposed being HEX encoded.
4715 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4718 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4719 functions: silc_[encode/decode]_pem. Also added function
4720 silc_encode_pem_file to PEM encode with newlines ('\n') for
4723 * SILC public keys are now encoded either PEM or binary. Same
4724 option is for private keys as well. By default private keys
4725 are binary encoded and public keys PEM encoded. Silly HEX
4726 encoding were removed.
4728 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4729 function to create fingerprints.
4731 * Fixed a bug in SHA1; does not change the original data anymore.
4733 * Partly implemented INFO command on client and server side.
4734 Fixed CLEAR command. Changes to SERVER command; show current
4735 server(s) when giving command without arguments. Added
4736 VERSION command to client.
4738 * Added check to server that unregistered connections cannot
4739 execute commands (unless it is specificly allowed).
4741 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Fixed screen refresh.
4745 * Fixed channel joining bug from client. On some circumstances
4746 client tried to join to a channel it had already joined.
4748 * Added public key verification process into client's protocol.c.
4749 The client now verifies the public key from user and saves
4750 it into ~./silc/serverkeys/ directory.
4752 Added into: clientutil.[ch]: silc_client_verify_server_key.
4754 * Changed SKE protocol's silc_ske_initiator_finish function
4755 to accept callback function that verifies the received public
4756 key. Removed old silc_ske_verify_public_key function.
4758 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4761 silc_pkcs_private_key[_data]_set.
4763 * Made the password and public authentication more cleaner in
4764 server's protocol.c.
4766 * Removed historic and obsolete protocol `channel_auth' from
4767 both client and server.
4769 * Removed wrong way of sending command status messages from
4770 server to client in server's command.c. The old way violated
4771 protocol specification.
4773 Changes to silccore/silccommand.[ch]: removed
4774 silc_command_encode_status_payload -> not needed anymore,
4775 changed silc_command_encode_payload_va to accept extra
4776 argument on variable argument list. The argument type must
4777 now be provided to the function. Also, added new function:
4778 silc_command_encode_reply_payload_va which is same as
4779 normal command_encode_payload_va except command status type
4780 is provided as extra argument.
4782 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4784 * Added ~./silc directory handling. The directory includes the
4785 public and private keys for the client.
4787 Added silc_client_check_silc_dir, silc_client_create_identifier
4788 and silc_client_load_keys.
4790 * Implemented SILC protocol compliant public key. Added public
4791 and private key saving to and loading from files.
4793 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4794 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4795 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4796 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4797 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4799 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4800 silc_pkcs_load_[public/private]_key.
4802 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Added silc_server_get_route (route.[ch]) to get connection
4805 data for the fastest route for given ID.
4807 * Implemented INVITE command on client and server. The command
4808 were re-defined in the SILC Protocol Specification and the
4809 implementation now complies with the specification.
4811 * Implemented PING command on client and server.
4813 * Implemented NAMES command on client and server. The server side
4814 supports currently only normal server not router server yet.
4815 Some changes to NAMES definition in SILC protocol specification.
4817 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Implemented LEAVE command on client and server.
4821 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4822 again. This change was made to the protocol as well. Server
4823 should not violate the protocol specification anymore.
4825 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4828 was tested. SOCKS4 was not but should work anyway.
