3 * Changed the get_auth_methdod client operation to be asynchronous.
4 It can be async if the application resolves the authentication
5 method from the server during the negotiation. Added new
6 SilcGetAuthMeth completion callback that the application will
7 call after resolving the authentication method.
9 Added function silc_client_request_authentication_method that
10 the application can use to resolve the authentication method
11 from the server. Added also SilcConnectionAuthRequest callback
12 that the library will call after the server has replied. The
13 application can call this function if it does not know the
14 current authentication method.
16 Affected files are lib/silcclient/client.c and
17 lib/silcclient/silcapi.h.
19 * The Irssi SILC client now automatically resolves the authentication
20 method incase any configuration information is not present (and
21 currently there never is). The affected file is
22 irssi/src/silc/core/client_ops.c.
24 * Fixed public key authentication from the client library.
25 Affected file lib/silcclient/protocol.c. Changed also the
26 protocol specification about the public key authentication in
27 the connection authentication protocol. The actual data to be
28 signed is now computed with a hash function before signing.
30 * Fixed the public key authentication from the server as well.
31 Affected file silcd/protocol.c.
33 * Removed the mlock()'s from the memory allocation routines.
34 Affected file lib/silcutil/silcmemory.c. The ./configure does
35 not check anymore for the mlock(). Affected file is
38 * Fixed USERS command in server to allow the execution of the
39 command for private and secret channels if the client sending
40 the command is on the channel. Affected file silcd/command.c.
42 * Fixed silc_client_get_clients_local to return the clients
43 count correctly. It could return wrong value. Affected file
44 lib/silcclient/idlist.c.
46 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
48 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
49 types. The assembler optimizations seemed not to like 64-bit
50 data types. The assmebler optimizations thus are now enabled
51 also for BSD systems as opposed to only enable them for Linux.
53 * Do not check for threads at all on BSD systems. Affected
54 file configure.in.pre.
56 * Removed -n and -h options from the Irssi SILC Client since
57 they are not used in silc.
59 * Fixed the prime generation to assure that the first digit
60 of the generated random number is not zero since our conversion
61 routines does not like number strings that starts with zero
62 digit. If zero digit is seen the random number is regenerated.
63 This caused some corrupted RSA keys when the zero first digit
64 was met. Affected file lib/silcmath/silcprimegen.c.
66 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
68 * Fixed WIN32 configuration in the ./configure script.
69 Fixed to include xti.h on environments that has it.
70 Patches by Carsten Ilchmann and andrew.
72 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
74 * Changed the silc_id_create_client_id to be collision
75 resistant. It is now assured that there cannot be created
76 two same client ID's. I suspect that some weird bugs in
77 the server were actually caused by duplicate Client IDs.
78 Affected file silcd/serverid.[ch]. A router receiving
79 new ID now also assures and informs the sending server
80 if the ID caused collision.
82 * Changed the silc_id_create_channel_id to also assure that
83 there are no collisions.
85 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
87 * Statement about ignoring the Mutual Authentication flag when
88 performing rekey with PFS was a bit misleading. It is ignored
89 if it was set in the initial negotiation, it cannot be even
90 set in the rekey. Fixed in the ke-auth draft. Started the
91 new versions of the protocol drafts in the doc/.
93 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Fixed a bug in silc_client_command_identify_save when saving
96 new channel information. The channel name was no duplicated
97 and caused crash on exit. Affected file is
98 lib/silcclient/command_reply.c.
100 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Fixed the getkey command handling in the server. Send just
103 empty OK reply to the sender if the key could not be fetched
104 (but everything else was ok, like the key just was not available).
105 Changed the public key parameter to optional in the protocol
106 specs so that empty OK reply can be sent. Affected file
109 Added a message to Irssi SILC client to tell to user if the
110 server did not return a public key.
112 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
114 * Fixed a channel key regeneration bug. It registered new
115 timeout tasks exponentially until all system resources were
116 used. Affected file silcd/server.c.
118 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
120 * Added the SILC Document generator to the scripts/silcdoc.
121 It can be used to generate the Toolkit Reference Manual out
122 of the source tree. Internally it will also use the RoboDoc
123 generator now imported in util/robodoc.
125 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
127 * Added couple of return's in rekey protocol if error orccurred
128 during the protocol. The execution must be terminated.
129 Affected file silcd/protocol.c. Also, terminate the protocol
132 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
134 * The client's Client ID was created initally from the wrong
135 nickname (it could have been in format nick@host) in the
136 silc_server_new_client. Affected file silcd/packet_receive.c
138 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
140 * Added some SILC_LOG_ERROR's to various error conditions
141 if client could not be added to ID cache. Affected files
142 silcd/packet_receive.c and silcd/server.c.
144 * When client's sock->user_data is freed, NULL also the
145 client->router and client->connection pointers. Added check
146 for these pointers being NULL to various places around the
147 code. Affected file silcd/server.c.
149 * Added client->data.registered == TRUE checks to various
150 places around the code to assure that unregistered client's
151 are not handled when it is not allowed. Affected file
154 * Added `bool registered' fields to all
155 silc_idlist_[server|client]_get_* routines to indicate whether
156 the fetched client needs to be registered or not. Affected
157 file silcd/idlist.[ch].
159 * Add your own entry as registered to the ID cache in the
160 server. Affected file server.c.
162 * Fixed a bug in silc_server_new_server. The SilcServer was
163 set as the new server's context instead of SilcServerEntry.
164 This naturally caused some weird bugs.
166 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
168 * Do not delete the channel rekey task when adding it
169 for in silc_server_create_channel_key.
171 * Changed the silc_server_create_channel_key to return
172 TRUE or FALSE to indicate the success of the channel key
175 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
177 * Fixed MSVC++ project files and added missing files to
178 Makefiles under win32/.
180 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
182 * Do not add TCP_NODELAY flag if the operating system
183 does not have it defined. Affected files are
184 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
186 * Fixed buffer overflow from Irssi SILC Client. Affected
187 file irssi/src/fe-common/core/themes.c.
189 * Fixed double free in client library in the file
190 lib/silcclient/client.c when disconnecting from server.
192 * Applied double free patch from cras to Irssi SILC client.
193 Affected files irssi/src/core/[modules/expandos].c
195 * Fixed the disconnection handling to Irssi SILC Client.
196 The application must call silc_client_close_connection
197 in ops->connect client operation in case of failure of
198 the connection. Affected file is
199 irssi/src/silc/core/client_ops.c.
201 * Do not set sock->protocol to NULL in the function
202 silc_client_close_connection after executing the protocol's
203 final callback since the sock might not be valid anymore.
204 Affected file lib/silcclient/client.c.
206 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Do not enable SILC_THREADS if the linking with libpthread
209 did not happen. Affected file configure.in.pre.
211 * Added notion to protocol specification that server must
212 verify the sent authentication payload with CMODE when
213 setting the channel founder key. Implemented it to the
214 server. Affected file silcd/command.c.
216 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Added _EXTRA_DIST SILC distribution variable to the
219 distributions file. It is used to conditionally add extra
220 files or directories to the specific distribution. Affected
221 files ./prepare, Makefile.am.pre and distributions.
223 Removed the `_' from the start of the distribution names.
226 * Added README.WIN32 for instructions to compile the Toolkit
229 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
231 * Fixed a double free in disconnection in the server. Affected
232 file is silcd/server.c.
234 * Fixed the lib/silcske/groups.c to work now also with GMP
235 MP library. The string conversion did not work when using
236 specific base and the base is indicated in the string as well.
238 * Created win32/ directory which now includes MSVC++ specific
239 stuff so that toolkit (DLLs) may be compiled with MSVC++.
240 It will appear only in the toolkit distribution
242 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
244 * Changed the key material distribution function in case when
245 the hash output is too short. The data is now concatenated
246 a bit differently than it used to. Made the change to the
247 SKE protocol specification.
249 * Added better GMP detection to configure.in.pre. A patch
252 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Fixed a minor bug in SKE that might cause some problem on
255 some platforms. Affected file lib/silcske/silcske.c.
257 * Added the cookie checking for initiator in the SKE. It checks
258 that the responder returns the sent cookie unmodified. The
259 affected file is lib/silcske/silcske.c. Added new SKE
260 error type INVALID_COOKIE that can be sent during the
261 negotiation. Fixed some memory leaks as well.
263 * Added the "invalid cookie" error message to Irssi SILC client's
266 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
268 * Added `task_max' field to the SilcClientParams to indicate
269 the maximum tasks the scheduler can handle. If set to zero,
270 default values are used. Affected file lib/silcclient/silcapi.h.
272 * Fixed memory leaks in silc_client_close_connection. Affected
273 file lib/silcclient/client.c.
275 * Added silc_client_del_client_entry to client library to free
276 all memory of given client entry. Affected file is
277 lib/silcclient/idlist.[ch].
279 * Added new functions silc_client_del_channel and
280 silc_client_del_server to delete channel and server entries.
281 Affected file lib/silcclient/[silcapi.h/idlist.c].
283 * Removed silc_client_del_client_by_id from silcapi.h.
285 * Fixed the INFO command to return the server's own info
286 correctly when querying by Server ID. Affected file is
289 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
291 * Removed the non-blocking settings in WIN32 code in the
292 silc_sock_[read/write] and added SleepEx instead. Affected
293 file lib/silcutil/win32/silcwin32sockconn.c. The availability
294 of input data is now checked with FIONREAD and ioctlsocket.
296 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
298 * Call silc_schedule_task_del_by_context in the
299 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
300 Affected file lib/silccore/silcprotocol.c.
302 * Call silc_protocol_cancel for active protocols in the
303 silc_server_close_connection if the funtion
304 silc_server_free_sock_user_data has not been called.
305 Affected file silcd/server.c.
307 * Generic tasks cannot be deleted using the del_by_fd
308 task deleting function since generic tasks does not match
309 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
311 * Added a notion to SILCOPER help file that the SILCOPER works
312 only on router server, not on normal server.
314 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
316 * Added for WIN32 support for the new scheduler as well.
317 Affected file lib/silcutil/win32/silcwin32schedule.c.
319 * Fixed the SHA1 implementation to work on various platforms.
321 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
323 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
324 API. It is part of the scheduler now. Everything else is
325 as previously but some functions has changed their names.
326 Checkout the lib/silcutil/silcschedule.h for the interface.
327 Updated all applications to use the new interface. Affected
328 files are lib/silcutil/silcschedule.[ch].
330 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
332 * Found a bug in the SKE implementation. The HASH value,
333 specified by the protocol, was not computed correctly. The
334 public key of the responder was not added to the computation
335 even though it is mandatory. Affected file lib/silcske/silcske.c.
336 This unfortunately causes incompatibilities with older
339 * Added WIN32 specific network init and uninit functions:
340 silc_net_win32_init and silc_net_win32_uninit to init and uninit
341 the Winsock2. Affected file lib/silcutil/silcnet.h and
342 lib/silcutil/win32/silcwin32net.c.
344 * Set the socket always to nonblocking mode on WIN32 after
345 reading data or writing data. Affected file is
346 lib/silcutil/win32/silcwin32sockconn.c.
348 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
350 * Fixed various compilation problems under WIN32. Affected
351 files lib/silcutil/win32/silcwin32thread.c and
352 lib/silcutil/win32/silcwin32schedule.c.
354 * Removed all _internal.h #includes from public header
355 files. Internal headers must never be included from
358 Removed also the lib/silcske/payload_internal.h file.
360 * All include files that may be needed (public and some others
361 included by the public headers) by application developers are
362 now copied to the ./includes directory. It does not copy any
363 internal headers. Affected file Makefile.defines.pre and all
364 Makefile.am's under lib/ and subdirs.
366 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
368 * Do not change the ~/.silc directory's permissions automatically.
369 Affected file irssi/src/silc/core/clientutil.c.
371 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
373 * Do not cancel the protocol in silc_server_close_connection
374 it might cause recursion. Now cancelled in the function
375 silc_server_free_sock_user_data. Affected file silcd/server.c.
377 * Fixed the silc_server_remove_clients_by_server to regenerate
378 the channel keys correctly finally. Added also new function
379 silc_server_remove_clients_channels to actually do it.
380 Affected file silcd/server.c.
382 * Fixed the silc_server_new_channel to not crash by giving
383 wrong router to the new channel. Affected file is
384 silcd/packet_receive.c.
386 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
389 which is given as argument to the silc_client_alloc now.
390 It can be used to configure the client and set various parameters
391 that affect the function of the client.
393 * The USERS command in server did not check whether the channel
394 is private or secret. Affected file silcd/command.c.
396 * Added new argument to the USERS command in protocol specification.
397 The USERS command now can take the channel name as argument
398 as well. Added support for this in client and server and
399 updated the protocol specs.
401 * Completed the GETKEY command in client. It can be now used
402 to fetch also servers public key not only some clients.
403 Affected files lib/silcclient/command[_reply].c.
405 * Added silc_client_get_server to return server entry by the
406 server name. Affected files lib/silcclient/silcapi.h and
409 * Redefined the IDENTIFY command in protocol specification to be
410 more generic. It now can be used to query information about
411 any entity in the SILC Network, including clients, servers and
412 channels. The query may be based either the entity's name
413 or the ID. Added support for this in both client and server.
415 Affected files silcd/command.c and lib/silcclient/command.c
418 * Optimized the WHOIS and WHOWAS commands in the server. Removed
419 the _from_client and _from_server functions. Affected file
422 * Added silc_client_get_channel_by_id_resolve to the file
423 lib/silcclient/silcapi.h to resolve channel information by
424 its ID. Added also silc_client_get_channel_by_id that
425 does not resolve it from the server.
427 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Added SilcServerEntry context into the client library
430 to represent one server. The INFO command now allocates
431 these to save the resolved server info. For now on the
432 client library will also keep information about servers,
433 connected and resolved with INFO.
435 The INFO command now allocates the SilcServerEntry context
436 and saves the server info there. The COMMAND_REPLY in
437 the INFO now returns the parameters to application in
438 same order as defined in the protocol specification.
440 The entries are cached in the client->server_cache.
442 * The INFO command is now issued after received the Client ID
443 from the server. Affected file lib/silcclient/client.c.
445 * The CMODE_CHANGE notify may now return also an SilcServerEntry
446 to the application as the mode changer might be server.
447 It is guaranteed that NULL is not returned anymore to the
448 application. Affected file lib/silcclient/client_notify.c.
450 The ID Type is now also passed to the application so that
451 it can check whether the returned entry is SilcClientEntry
454 Added new function silc_client_get_server_by_id to return
455 the server entry by ID. Affected files are the
456 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
458 * Do not create the channel in the Irssi SILC Client when issuing
459 the JOIN command but when received the sucessful JOIN command
460 reply. Otherwise the channel might get created even though we
461 could not join it. The Affected file is
462 irssi/src/silc/core/[silc-channels.c/client_ops.c].
464 * Fixed a channel joining bug in router. The router must also
465 check the channel modes, invite and ban lists etc. when serving
466 the JOIN command sent by normal server. Affected file is
467 silcd/command.c. The router now resolves the client's
468 information from the server who sent the JOIN command if it
469 does not know it, and processes the JOIN command only after
472 * Changed the SilcCommandCb to take new argument; void *context2.
473 Affected file lib/silccore/silccommand.h
475 The second argument in the command callbacks in the server now
476 includes the SilcServerCommandReplyContext if the command was
477 called as pending command callback from the command reply.
478 Otherwise it is NULL. When called as pending the status of the
479 command reply will be checked and if it was erronous the
480 error will be sent to the original sender of the command.
481 This way the client always receives the error messages even
482 though the server was actually the one who received the error
483 when it resent the command to router, for example. Affected
484 files silcd/command[_reply].[ch].
486 * Fixed sending WHOWAS command's error message to client if
487 the requested client could not be found. It was missing.
490 * Changed the CMODE and CUMODE commands reply arguments in the
491 protocol specification. The Channel ID is now sent in both
492 of the commands to identify the channel. Implemented this
493 new feature to the client and server. Affected files
494 lib/silcclient/command_reply.c and silcd/command.c.
496 * Made better checks for invite and ban lists in the JOIN
497 command in server. Affected file silcd/command.c.
499 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
501 * The server now performs the incoming host IP/DNS lookup
502 using the silc_socket_host_lookup and thus does not block
503 the server anymore. Affected file silcd/server.c.
505 * Completed the multi-thread support for SILC Scheduler in
506 the lib/silcutil/silcschedule.c.
508 * Fixed the configure.in.pre to detect the pthread correctly
511 * Fixed a deadlock in silc_task_queue_wakeup in the file
512 lib/silcutil/silctask.c.
514 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
516 * Added new function silc_schedule_wakeup that is used in
517 multi-threaded environment to wakeup the main thread's
518 schduler. It needs to be used when a thread adds a new task
519 or removes a task from task queues. After waking up, the
520 scheduler will detect the task queue changes. If threads
521 support is not compiled in this function has no effect.
522 Implemented the wakeup mechanism to both Unix and WIN32
523 systems. Affected files are lib/silcutil/silcschedule.[ch],
524 lib/silcutil/unix/silcunixschedule.c and the
525 lib/silcutil/win32/silcwin32schedule.c.
527 * Added new function silc_task_queue_wakeup to wakeup the
528 scheduler by the specified task queue. Affected file
529 lib/silcutil/silctask.[ch].
531 * The silc_socket_host_lookup_start now wakes up the scheduler
532 after adding the timeout task. Affected file is
533 lib/silcutil/silcsockconn.c.
535 * The silc_socket_host_lookup is synchronous now if the threads
536 support is not compiled in. However, the callback is still
537 called asyncronously through the scheduler, anyway. Affected
538 file lib/silcutil/silcsockconn.c.
540 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Added new function silc_socket_host_lookup to perform
543 asynchronous IP and FQDN lookups for the socket connection.
544 Affected files lib/silcutil/silcsockconn.[ch].
546 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
548 * Added SILC_MUTEX_DEFINE to define the mutex on environments
549 that may or may not compile the mutex support in.
551 Changed the silc_mutex_alloc interface. It allocates the
552 mutex now to the sent pointer and returns TRUE or FALSE.
554 Affected file lib/silcutil/silcmutex.h.
556 * Wrote the SILC Task Queue interface to support multi-threads.
557 Affected file lib/silcutil/silctask.[ch].
559 * Wrote the SILC Scheduler to support multi-threads. Affected
560 file lib/silcutil/silcschedule.c.
562 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
564 * Implemented the SILC Mutex API and SILC Thread API for WIN32
565 in lib/silcutil/win32/.
567 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Defined SILC Mutex API and SILC Thread API and implemented
570 them for Unix. Affected files are
571 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
572 lib/silcutil/unix/silcunixmutex.c and
573 lib/silcutil/unix/silcunixthread.c.
575 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
577 * Fixed the silc_server_remove_clients_by_server's channel
578 key re-generation. The hash table handling was incorrect
579 and would not work with many channels. Affected file is
582 * Fixed some memory leaks around the server code.
584 * Rewrote the silc_server_get_users_on_channel to support IPv6
585 based Client ID's. Affected file silcd/server.c.
587 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
588 specification. However, a separate document must be written
589 to define the detailed signing procedure and the payload
590 associated with the flag. Defined the flag to the
591 lib/silccore/silcchannel.h as well.
593 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
595 * Changed the dynamic tables to static size tables in the
596 lib/silccrypt/silchmac.c.
598 * Removed GCC dependencies from the code. A patch by cras.
600 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
602 * Do not show the error "Error receiving packet bla bla"
603 in server if it really was not an error (-2 means that reading
604 is pending). Affected file silcd/server.c.
606 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
608 * Fixed a possible crash in silc_server_remove_clients_by_server
609 in silcd/server.c. Fixed there also some memory leaks.
611 * Fixed the silc_idlist_replace_client_id. It could replace
612 wrong key in the hash table. Affected file silcd/idlist.c.
614 * Do not check whether there are global users on the channel
615 if the channel->global_users is FALSE. Affected functions
616 silc_server_remove_from_one_channel and
617 silc_server_remove_from_channels in silcd/server.c. Also,
618 do not check if the removed client is local as we can be
619 sure that global client was not removed from the channel
620 and checking for global users is not needed.
622 * The silc_server_remove_clients_by_server now re-generates
623 the channel keys correctly for those channels that had
624 clients removed from them. Affected file silcd/server.c.
626 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
628 * Found the reason of random crashes in the server. We weren't
629 ignoring the SIGPIPE signal (which can be sent in write())
630 and it crashed the server. Affected file silcd/silcd.c.
632 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Assure that sock->user_data is not NULL in the function
635 silc_server_packet_send in silcd/packet_send.c.
637 * Disconnect the remote connection if it could not be added
638 to any ID lists in the server. The affected file is
641 * Check in silc_server_packet_send[_real/dest] that the
642 socket is not disconnecting and ignore the data if it is.
643 Affected file silcd/packet_send.c.
645 * Define inline to __inline on native WIN32 compilation.
646 Affected file includes/silcwin32.h.
648 * Added some explicit type casts for inline code since MSVC
649 require them. Affected files lib/silcutil/silcbuffer.h,
650 lib/trq/silcdlist.h and lib/trq/silclist.h.
652 * Print warning in log files from now on if the packet
653 decryption fails. Affected file silcd/server.c.
655 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
657 * Changed the `say' client operation's interface to accept
658 new `type' argument to indicate the type of the message sent
659 by the library. The application may filter the library's
660 messages according the type. The affected file is the
661 lib/silcclient/silcapi.h.
663 * Added two new functions to lib/silcclient/silcapi.h:
664 silc_client_del_client and silc_client_del_client_by_id.
665 Affected file lib/silcclient/idlist.c.
667 * Moved the clientincludes.h from includes/ to silc/ and
668 serverincludes.h from includes/ to silcd/.
670 * The modes for the CMODE and CUMODE are now passed as
671 uint32 for application with COMMAND_REPLY. The affected
672 file is lib/silcclient/command_reply.c.
674 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
676 * /WHOIS without arguments shows client's own information.
677 Affected file lib/silcclient/command.c.
679 * Changed PING to not accept any arguments. The specs
680 says that client can ping only the connected server so
681 requiring an argument is not needed. Affected file is
682 lib/silcclient/command.c.
684 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Fixed a fatal bug in private message sending and reception
687 encryption and decryption when using private message keys.
688 The implementation was incorrect and did not follow the
689 specification. It causd that some of the message were
690 lost since it did not use the sending and receiving keys
691 as the protocol suggests. This has been fixed and will cause
692 incompatibilities with older clients when sending private
693 message encrypted with private message keys. Affected files
694 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
695 and various other in Irssi SILC Client.
697 Added `responder' boolean argument to the functions
698 silc_client_add_private_message_key[_ske] to indicate when
699 the key is added as responder or initiator of the key
702 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Removed the silc_ske_check_version function and created
705 a SilcSKECheckVersion callback. Added also a function
706 silc_ske_set_callbacks that is now used to set all SKE
707 callbacks. The callback functions are not given to
708 the SKE functions anymore, but this function is used to
711 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
713 * Added `silc_version' argument to the silc_client_alloc
714 to define the version of the application for the library.
715 The library will use the version string to compare it
716 against the remote host's (usually a server) version
717 string. Affected file lib/silcclient/silcapi.h
719 * Added the KE protocol context to Key Agreement context
720 in client library so that we can abort the SKE if it
721 is in process when we get timeout. Affected file is
722 lib/silcclient/client_keyagr.c.
724 * Do not resolve the client ID forever if it returns in the
725 first time that such client does not exist. This was done
726 for example with private message. Affected file is
727 lib/silcclient/client_prvmsg.c.
729 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
731 * Do not add regex.h for WIN32. The affected file
732 includes/silcincludes.h.
734 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
735 not work yet 100%. It generates the DLL's automatically
736 when compiling with --with-win32 under cygwin.
738 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
740 * lib/contrib/regex.c is not compiled on WIN32.
742 * Added silc_net_get_socket_opt function to the
743 lib/silcutil/silcnet.h.
745 * Added includes/silcwin32.h for WIN32 specific includes
748 * Do not use ptime structure or any of the posix process
749 functions on WIN32 in lib/silccrypt/silrng.c.
751 * Added silc_gettimeofday to provide generic function
752 for struct timeval on all platforms. Added the function
753 to lib/silcutil/silcutil.h.
755 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Moved the lib/silccore/silcsockconn.[ch] to the utility
758 library as they clearly belong there. As a plus side we
759 can make the actual socket connection routines platform
762 Added also new generic function silc_socket_read and
763 silc_socket_write (that used to be silc_packet_[read/write].
764 The implementation of these are platform specific.
766 * Added WIN32 specific routines of silc_socket_[read/write]
767 to lib/silcutil/win32/silcwin32sockconn.c.
769 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Added preliminary support for native WIN32 compilation under
772 cygwin (using the -mno-cygwin option for GCC) to the
773 ./configure.in.pre. The --with-win32 now prepares the
774 compilation for native WIN32.
776 * Rewrote the SILC Scheduler interface in the file
777 lib/silcutil/silcschedule.h. The scheduler is now context
778 based and does not have anymore any global static scheduler.
779 Moved the Unix scheduler to the lib/silcutil/unix/ directory
780 and created lib/silcutil/win32 directory for WIN32 based
783 * Added Unix specific network routines to the
784 lib/silcutil/unix/silcunixnet.c and the old
785 lib/silcutil/silcnet.c includes now only generic routines.
787 Added WIN32 specific network routines to the
788 lib/silcutil/win32/silcwin32net.c.
790 * Added Unix specific utility functions from the
791 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
793 * Added WIN32 SILC Scheduler to the file
794 lib/silcutil/win32/silcwin32schedule.c. The code is of course
797 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Do not handle JOIN notify in the server if the target client
800 is not registered (idata->registered == FALSE). The affected
801 file is silcd/packet_receive.c.
803 * Update the nickrec->founder in event_cumode in the Irssi SILC
804 client. Affected file irssi/src/silc/core/silc-channels.c.
806 * Fixed the CUMODE_CHANGE notify handling in the server when
807 server and router are announcing their clients on channels.
808 Now the mode changes are saved and notified correctly. The
809 affected file is /silcd/packet_receive.c.
811 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
812 They really did not replace the cache entry in the ID Cache.
813 Now they do that. Affected file silcd/idlist.c.
815 * Fixed the KICK notify handling in the Irssi SILC client to
816 update the channel records so that the kicked client does not
817 appear to be on the channel. The affected file is
818 irssi/src/silc/core/silc-channels.c.
820 * Always update the conn->current_channel when executing command
821 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
823 * Fixed the KILL notify handling in Irssi SILC client to remove
824 the killed client on all channels.
826 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
828 * Fixed the silc_parse_command_line to remove extra spaces
829 from the start and end of the arguments. Affected file is
830 lib/silcutil/silcutil.c.
832 * Cancel and free any active protocol in the function
833 silc_server_close_connection. Affected file silcd/server.c.
835 * Cancel and free any active protocol in the function
836 silc_client_close_connction. Affected file is
837 lib/silcclient/client.c.
839 * Do not execute the KILL command for clients that are in
840 history (ie. they are not in the network). Affected file is
843 * Fixed KILL notify handling, client does not crash anymore.
844 Affected file irssi/src/silc/core/silc-channels.c.
846 * Reduced the default packet buffer size from 2048 to 1024 in
847 lib/silccore/silcpacket.c.
849 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
850 counter to the SKE context that is incresed when the SKE library
851 performs async operation outside the library. If the outside
852 process frees the SKE context and FREED status will be set
853 and the library will detect after the sync operation that the
854 libary is freed. The affected files are
855 lib/silcske/silcske[_status].[ch].
857 * Resolve the client entry information in the function
858 silc_client_channel_message to assure that NULL pointer is not
859 passed as client entry to the application. */
861 * Fixed the task timeout calculation to assure that there is
862 never negative timeouts. The affected file is
863 lib/silcutil/silcschedule.c.
865 * Fixed the channel user mode notification sending in server.
866 It was sent point-to-point to the router (or to server by router)
867 but it needs to be destined to a channel. The routines now
868 supports sending the channel user mode notifys to the channels
869 when announcing clients and channels. Affected files are
870 silcd/server.c and silcd/packet_receive.c.
872 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
873 It did not actually replace the old channel entry in the cache.
874 Affected file lib/silcclient/client_notify.c.
876 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Fixed a possible crash in silc_packet_send_prepare. It now
879 assures always that there is enough space in the buffer and
880 at the tail area of the buffer (for MAC).
882 Fixed the inbound buffer reallocation in silc_packet_read.
883 It was old code and did not handle the reallocation correctly.
886 The affected file is lib/silccore/silcpacket.c.
888 * Fixed buffer overflow in silc_parse_nickname in the file
889 lib/silcutil/silcutil.c.
891 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * make install generates new server keys only if there is not
896 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
899 Added check that if the NOREPLY is set then we will not send
900 the away message. This avoids infinite loop of away messages
901 if both clients are away. The affected file is
902 lib/silcclient/client_prvmsg.c.
904 * Fixed client crash if /NICK was given without arguments.
905 Affected file lib/silcclient/command.c.
907 * Server does not send the invite list in INVITE command back
908 to the client if the list was not altered. Added this notion
909 to the protocol spec as well. Affected file silcd/command.c.
911 Fixed possible crash in INVITE command by checking the
912 value of silc_server_get_client_route command.
914 * Fixed the INVITE notify type handling. The arguments are now
915 taken in correct order and client does not crash. The affected
916 file is irssi/src/silc/core/silc-channels.c.
918 Removed the "Inviting xxx to channel" message from the
919 client library away and let the application handle it.
920 Affected file lib/silcclient/command.c. Added that message
921 to Irssi SILC client's message formats.
923 * Fixed CMODE command crash in client. It now checks the
924 amount of arguments correctly and does not crash. The affected
925 file is lib/silcclient/command.c.
927 * Do not create new channel automatically in silc_channels_join
928 but check whether the channel by that name already exists.
929 Affected file irssi/silc/core/silc-channels.c.
931 * Do not send the SERVER_SIGNOFF to router if the disconnected
932 entity was the router. Affected file silcd/server.c.
934 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
935 SILC client as it was missing from there.
937 Added the handling of the KICK notify to the Irssi SILC client
938 as it was missing. Added "you have been kicked" message to
939 Irssi SILC client's message modules formats.
941 Added the handing of the KILL notify to the Irssi SILC client
942 as it was missing. Added the kill message module formats
945 The affected file is irssi/src/silc/core/silc-channels.c.
947 * The router did not save the channel mode the server announced.
948 Affected file silcd/packet_receive.c.
950 * Fixed a possible crash in INFO command in server. If the
951 server did not provide the server info it crashed. Affected
952 file silcd/command.c.
954 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Fixed the GETKEY command in the server to check also the
957 global list. Otherwise the GETKEY would not work correctly
958 in normal SILC server. Affected file silcd/command.c.
960 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Fixed GETKEY crash, it crashed if the command did not succseed.
964 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
967 is now real and not just an macro interface to GMP.
969 Removed the entire GMP from the source tree and imported new
970 NSS MPI library instead. Reason for removing GMP is that it is
971 extremely large and compiles extremely slow. The NSS MPI
972 is only a few files and compiles in less than 10 seconds.
973 The speed is also about the same as GMP. The MPI is imported
976 If the system has GMP installed we will still use the GMP.
977 If it is not then the NSS MPI will be compiled.
979 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Merged a long nickname (127 characters long) crash bugfix from
982 Irssi CVS tree. Affected file irssi/src/core/misc.c.
984 * Merged a freed memory reference bugfix from Irssi CVS tree.
985 Affected file irssi/src/core/commands.c.
987 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Added the server's public key sving and verification to the
990 server when performing the SKE. This was missing and the
991 remote server's (or router's) public key was accepted without
992 checking whether we have it previously or trust it at all.
993 Affected file silcd/protocol.c.
995 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Check in the silc_server_timeout_remote if protocol is active
998 and make sure that the protocol's final callback is called so
999 that all memory if freed. Affected file silcd/server.c.
1001 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * silc_server_whois_send_reply crashed the server if the nickname
1004 was 127 characters long. Affected file silcd/command.c.
1006 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1008 * Added sanity check to the silc_server_new_client. If the hostname
1009 is provided inside username then check that the provided hostname
1010 really is the same as the resolved one. If the hostname was not
1011 resolved then check it from the public key. Affected file is
1012 silcd/packet_receive.c.
1014 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1015 if the server disconnected us and the connection is not valid
1016 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1018 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1019 the library to the lib/silcutil/silcutil.[ch].
1021 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Close log file after open. Affected file
1024 lib/silcutil/silclog.c.
1026 * Check whether sock == NULL in silc_client_send_packet and return
1027 if it is. Affected file lib/silcclient/silcclient.c.
1029 * Check rec->entry == NULL in the Irssi SILC Client before
1030 sending the channel message. Affecte file is
1031 irssi/src/silc/core/silc-servers.c.
1033 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Merged a splitted window bugfix from Irssi CVS tree. The
1036 affected file is irssi/src/fe-text/textbuffer-view.c.
1038 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1039 It did not print nickname.
1041 * Improved the distributions system a bit.
1043 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1045 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1046 irssi/src/fe-text/gui-window.c.
1048 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1049 to in-active server. The affected file is
1050 irssi/src/silc/core/client_ops.c.
1052 * Resolve the client in USERS command reply if the entry does
1053 not have username resolved. The affected file is
1054 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1055 command to WHOIS command to really resolve stuff. The USERS
1056 is not used any more in any critical section so WHOIS can
1057 be used even though it might be slower than IDENTIFY.
1059 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1062 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * Changed the protocol API a bit more consistent in the
1065 lib/silccore/silcprotocol.[ch].
1067 * Changed the following headers to ROBODoc format:
1069 lib/silccore/silcpayload.h
1070 lib/silccore/silcprotocol.h
1071 lib/silccore/silcsockconn.h
1073 All core library headers are now formatted.
1075 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Fixed a bug in Irssi SILC client; do not show that you are
1078 server/router operator if you really are not. Affected file is
1079 irssi/src/silc/core/client_ops.c.
1081 * Renamed silc_command_free_payload to silc_command_payload_free.
1082 Affected file lib/silccore/silccommand.h
1084 * Added silcmath.h to include the prototoypes of various routines
1085 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1088 * Changed the following headers to ROBODoc format:
1090 lib/silccore/silcchannel.h
1091 lib/silccore/silccommand.h
1092 lib/silccore/silcid.h
1093 lib/silccore/silcidcache.h
1094 lib/silccore/silcmode.h
1095 lib/silccore/silcnotify.h
1096 lib/silccore/silcpacket.h
1097 lib/silcmath/silcmath.h
1099 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Added checking to the server code not to start the server if
1102 ciphers and stuff are not configured properly. Affected files
1103 silcd/serverconfig.[h] and silcd/server.c.
1105 * Changed the layout of the header files of the public interfaces
1106 in the SILC libraries. The new layout supports ROBODoc
1107 documentation tool (and some others) so that it is easy to create
1108 a library reference manual. All the other headers and source
1109 code must still follow the CodingStyle document. Also source
1110 code must not include these ROBODoc stuffs, only the headers.
1111 Furthermore, all public interface headers must now be named
1112 by using `silc' prefix, example: silcapi.h, silccipher.h.
1113 Some files were renamed due to this. All the other headers
1114 must not be used as public interfaces. I will update the
1115 CodingStyle document later. Changed following headers, so far:
1117 lib/silcclient/silcapi.h
1118 lib/silccore/silcauth.h
1119 lib/silccore/silcprivate.h
1120 lib/silccrypt/silcdh.h
1122 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Removed silc_client_packet_send_flush from the client library
1127 as it is not needed. Affected file lib/silcclient/client.[ch].
1129 * Added printing of message of unresolved authentication method
1130 to the Irssi SILC client. Added it to the module formats.
1131 Removed the same message from the client library.
1133 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Added new distribution feature, DISTLABEL. Every distribution
1136 can define own preprocessor label that can be used in the
1137 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1138 file distributions, acconfig.h.pre and prepare.
1140 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Added Makefile.defines_int to include the actual definitions
1143 for Makefile.defines.in. Tested the new distribution system,
1144 created distributions and tested installation.
1146 * Added AWAY message printing to the Irssi SILC client. Added
1147 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1149 * Added SCONNECT command to call the SILC's CONNECT command.
1150 Cannot use CONNECT directly since Irssi uses that internally.
1151 Affected file irssi/src/silc/core/silc-servers.c.
1153 Added ACTION local command. It is same as ME command but takes
1154 the channel as mandatory argument.
1156 Rewrote some of the Irssi's help files to suite for SILC
1159 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Added Makefile.defines[.in] that should for now on be included
1162 in all Makefile.am file in the source tree. That file includes
1163 all common compilation definitions for SILC source tree.
1165 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Minor changes to the ./prepare script to change the package
1168 name according the distribution name to the configure.in.
1170 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Created new distribution system. Added file `distributions'
1173 that defines all the distributions that can be created out of
1174 the SILC source tree. The ./prepare script now reads that
1175 file to determine how to prepare the distributions. The
1176 first argument to the ./prepare is the name of the distribution
1177 and second is the version of the distribution. If given
1178 without arguments it creates the default (toolkit) distribution
1179 with the default version (defined in ./prepare).
1181 All Makefile.am files that are subject to the distributions
1182 are now named as Makefile.am.pre. These are ./Makefile.am
1183 and lib/Makefile.am. Others may be changed later.
1185 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Added invite list, ban list, some key management and connection
1188 error message printing to module formats in the Irssi SILC client.
1190 * Added new silc_client_set_away_message to set the away message
1191 that is back to the person who sent private message. The
1192 affected file lib/silcclient/silcapi.h and the
1193 lib/silcclient/client_prvmsg.c.
1195 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1197 * Fixed the private message sending in the Irssi SILC client,
1198 added local command KEY to the Irssi SILC client.
1200 Added key management and key agreement message formats to the
1201 irssi/src/fe-common/silc/module-formats.[ch].
1203 Added USERS (alias WHO) printing, server/router operator
1204 indication and LIST command printing to the module formats.
1206 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Fixed channel joining notify handling, cumode notify handling
1209 from Irssi SILC client.
1211 * Added SILC specific module-formats to the Irssi SILC client so
1212 that SILC specific message hilighting, colors etc is possible.
1213 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1215 Added channel mode, channel user mode, actions, notices,
1216 whois and whowas printing to the the module-formats.c.
1218 * Fixed a bug in channel deletion in the server. The channel
1219 is not left to the cache even if the channel founder auth mode
1220 is set when there are no users anymore on the channel. Affected
1221 file silcd/server.c.
1223 * The silc_net_localhost now resolves the entire hostname including
1224 the domain name. Affected file lib/silcutil/silcnet.c.
1226 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1228 * Changed the ask_passphrase client operation to be ascynchronous.
1229 It has now a completion callback and a context that the
1230 application must call after it has got the passphrase from
1231 the user. Affected files lib/silcclient/silcapi.h,
1232 lib/silcclient/protocol.c, lib/silcclient/command.c and
1235 Added SilcAskPassphrase callback that the application calls
1236 to deliver the passphrase to the library.
1238 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1239 The public key verification and especially a certificate
1240 verification is asynchronous procedure.
1242 Added new SILC_SKE_STATUS_PENDING status to indicate the
1243 request is pending and a callback will be called to finalize
1246 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1247 indicate that remote end did not send its public key (or
1248 certificate), even though we require it. Added check for this
1249 condition in the SKE. This was a security bug, now fixed.
1251 Defined new SilcSKEVerifyCbCompletion callback that is called
1252 when the verification process is completed.
1254 The affected files lib/silcske/silcske_status.h and
1255 lib/silcske/silcske.[ch].
1257 * Changed the verify_public_key client operation to be async
1258 as well. Defined SilcVerifyPublicKey callback that is used to
1259 indicate the success of the public key verification process.
1261 Changed the server and client to use the new async client
1264 * Changed the Irssi SILC client's internal scheduler to be called
1265 twice as many times as it used to be. As a result the client
1266 should be a bit faster now. Affected file is
1267 irssi/src/silc/core/silc-core.c.
1269 * Added support to Irssi SILC client of asynchronous public key
1270 verification and passphrase inquiry. Affected file is
1271 irssi/src/silc/core/silc-core.c.
1273 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Do not say "You have left channel %s" in client library.
1276 Moved it to the application. Affected files are
1277 lib/silcclient/command.c and silc/client_ops.c.
1279 * Fixed silc_client_get_clients. Command context was not
1280 duplicated and was freed memory in the callback. Affected
1281 file lib/silcclient/idlist.c.
1283 * Do not say "you are now talking..." on JOIN command in the
1284 client library. The appliation must handle it.
1286 * Do not say ".. changed topic to" in command reply in the
1287 client libary. The application must handle it.
1289 * Fixed TOPIC command sending in the client library.
1291 * Fixed a memory leak in silc_client_command_free in the file
1292 lib/silcclient/command.c.
1294 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Imported a modified version of Irssi client to the source tree.
1297 The Irssi will be used to create a new client called
1298 Irssi SILC. Imported to irssi/.
1300 Added silc_core_init_finish function to the Irssi. Affected
1301 file irssi/configure.in.
1303 A lot changes in the Makefile.ams around the irssi tree.
1305 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Do not rehash if the new size is same as the old size of the
1308 hash table, in the silc_hash_table_rehash*. The affected file
1309 lib/silcutil/silchashtable.c.
1311 * Replaced hash_table_del_by_context calls from the server
1312 (when channel->user_list and client->channels) to the
1313 hash_table_del as it is sufficient and faster.
1315 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1317 * Added silc_hash_table_list, silc_hash_table_get and the
1318 SilcHashTableList structure to provide an alternative way to
1319 traverse the hash table. The affected files are
1320 lib/silcutil/silchashtable.[ch].
1322 * Changed the server's idlist routines to use the hash table
1323 routines to optimize the code.
1325 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Replaced the client entry's `channel' list and channel entry's
1328 `user_list' list to hash tables for optimized lookup. Changed
1329 the code to use the hash table interface around the code.
1330 Affected file lib/silcd/idlist.[ch].
1332 * Added `auto_rehash' boolean argument to the function
1333 silc_hash_table_alloc to indicate whether the hash table should
1334 auto-rehash when it thinks is appropriate time. It will
1335 increase the hash table size if the there is twice as much
1336 entries in the table than the size of the table, and will
1337 decrease the size if there are twice as less entries than
1338 the size of the table.
1340 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1342 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1344 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * silc_idcache_purge_by_context deletes the entry now by context
1347 as it is supposed to do. Affected file lib/silccore/idcache.c.
1349 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1350 client is not anymore valid (WHOWAS givens the info) and not
1351 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1353 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1355 * Removed the `data' and `data_len' arguments from the ID Cache
1356 interfaces and added `name' argument. ID Cache does not handle
1357 anymore the binary data only a names associated with given ID.
1359 * When hashing a Client ID with silc_hash_id the entire ID is
1360 not hashed anymore, instead only the hash of the Client ID is
1361 hashed. This way we can access the Client ID from the cache
1362 with Client ID but with the hash of the ID (which is a hash of
1363 the nickname) as well without any difference in performance.
1365 Added also silc_idcache_find_by_id_one_ext to do one on one
1366 searching when we have the actual ID. Added also function
1367 silc_hash_client_id_compare. The affected files are
1368 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1370 * When hashing the name associated with a ID it is always done
1371 in lowercase. This way we can access the cache without worrying
1372 about case-sensitivity, even though, for example nicknames are
1375 * Fixed a bug in server with channel message sending. It put
1376 wrong ID type as destination ID. The affected file
1377 silcd/packet_send.c.
1379 * silc_idcache_del_by_context now deletes from all hash tables
1380 by context. Affected file lib/silccore/idcache.c.
1382 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Changed the client library to use the new ID Cache interface.
1385 Changes around the source tree.
1387 * Added silc_hash_table_rehash_ext to rehash with specific
1388 hash function. Affected file lib/silcutil/silchashtable.[ch].
1390 * Added silc_hash_string_compare to compare two strings in the
1391 hash table. Affected file lib/silcutil/silcutil.[ch].
1393 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Added new function silc_idcache_del_by_context into the
1396 lib/silccore/idcache.[ch].
1398 * Changed the server's ID list routines to use the new ID Cache
1399 interface. Changes around the source tree.
1401 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Added silc_hash_table_del[_by_context]_ext functions in to the
1404 lib/silcutil/silchashtable.[ch].
1406 Removed silc_hash_table_find_all* routines and added new
1407 silc_hash_table_find_foreach to replace them.
1409 Added silc_hash_table_replace_ext function as extended
1410 replacing function. Separated the simple hash table interface
1411 from the extended hash table interface in the file
1412 lib/silcutil/silchashtable.h.
1414 * Fixed minor bugs and changed it to use some of the new
1415 hash table functions in lib/silccore/idcache.c
1417 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Added new function silc_hash_table_find_all to return all keys
1420 in the hash table by the specified key. As the hash table is
1421 collision resistant it also makes it possible to have several
1422 duplicate keys in the hash table. This function may be used to
1423 find all of the keys from the hash.
1425 Added user_context arguments to the SilcHashFunction,
1426 SilcHashCompare and SilcHashDestructor to deliver user specified
1429 Added new fuctions silc_hash_table_find[_all]_ext to do
1430 extended lookup with specified hash and compare functions and
1431 specified user contexts.
1433 Added new function silc_hash_table_add_ext to add the key
1434 with specified hash function and user context.
1436 Added new function silc_hash_table_foreach to traverse all
1437 entrys in the hash table. Added SilcHashForeach callback
1440 Added new function silc_hash_table_del_by_context to delete
1441 the entry only if the context associated with the key matches.
1443 Affected files are lib/silcutil/silchashtable.[ch].
1445 * Removed silc_hash_[server/client/channel]_id and added just
1446 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1447 silc_hash_id_compare to compare two ID's using as the hash table
1448 comparison function. Added also silc_hash_data to hash
1449 binary data and silc_hash_data_compare to compare it.
1451 * Removed silc_idlist_find_client_by_hash as it is not needed
1452 anymore. Affected file silcd/idlist.[ch].
1454 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1455 to use internally the SilcHashTable. The new ID Cache is a lot
1456 faster than the old one. Some of the ID Cache interface was also
1457 rewritten and obsolete and stupid functions were removed.
1459 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1461 * Added entry_count field to the SilcHashTable to keep the number
1462 of the entries in the table. Implemented the function
1463 silc_hash_table_rehash. Added new function
1464 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1466 Fixed a minor bug in silc_hash_table_free.
1468 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1469 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1470 into the lib/silcutil/silcutil.[ch].
1472 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Implemented a collision resistant hash table into the
1475 lib/silcutil/silchashtable[ch]. See the header and the source
1476 for the SilcHashTable API.
1478 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1480 * Merged dotconf version 1.0.2 into lib/dotconf.
1482 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1484 * Do not compile anything in lib/silcsim/* if the SIM support
1485 is not enabled. The tree should now compile without problems
1488 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Compiled the SILC under cygwin. Compiled and tested briefly
1491 without problems. More tests needed. The SIMs didn't compile
1494 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1496 * Fixed possible crash in silc_get_username in the
1497 lib/silcutil/silcutil.c.
1499 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * Fixed a va_arg in silc/client_ops.c.
1503 * Oops, RC5 routines were named AES and caused some problems
1504 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1506 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Added new SilcIDIP structure into the lib/silccore/id.h and
1509 replaced the old `ip' fields from all SILC ID's to that type.
1510 This is a step towards IPv6 support.
1512 The silc_id_get_len takes now the ID as an extra argument.
1513 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1514 both IPv4 and IPv6 based ID's.
1516 The affected files are lib/silccore/id.[ch] and other files
1517 around the tree using these routines.
1519 * Removed the ID length arguments in server from various
1520 silc_server_send_notify_* routines -> they are not needed
1523 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * Fixed memory leak in silc_encode_pem_file in the file
1526 lib/silcutil/silcutil.c.
1528 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Check minor version as well in the SKE. Affected files are
1531 silcd/protocol.c and lib/silcclient/protocol.c.
1533 * Added --identifier option to the server so that an identifier
1534 can be when creating the public key for the server. Affected
1535 file is silcd/silcd.c.
1537 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1538 lib/silccrypt/silcpkcs.c.
1540 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Register default ciphers and stuff when using -C option with
1543 the server. Affected file sildc/silcd.c.
1545 * Put back the servers public key filename format, it is better
1546 than the new one. For now, the client keys are saved with the
1547 new filename format. The affected file silc/client_ops.c.
1549 * Implemented the Cipher API for the rest of the ciphers that
1550 did not implement it or implemented it the wrong way.
1552 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Register default ciphers and stuff when using the -S option
1555 in the client. Affected file silc/silc.c. Same also when
1556 creating new key pair with -C option.
1558 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Fixed the silc_verify_public_key client operation function to
1561 save the public keys differently. The fingerprint is now
1562 used as filename and not the hostname. This way also the
1563 client keys are saved uniquely and not with hostnames. The
1564 affected file is silc/client_ops.c.
1566 * Trimmed the silc_hash_fingerprint function to remove extra
1567 whitespaces from the end of the fingerprint. The affected
1568 file is lib/silccrypt/silchash.c.
1572 * Added silc_cipher_register_default function to register all
1573 default ciphers. It can be used when configuration files
1574 does not exist and the application does not want any specific
1575 ciphers in any specific order.
1577 The SilcDList is now used as silc_cipher_list dynamically
1578 allocated cipher list. Removed the static list all together
1579 and now all ciphers must be allocated to the dynamic list.
1580 The silc_cipher_alloc routine was changed to check only the
1583 All silc_cipher_* routines that used to return int returns
1586 The affected files lib/silccrypt/silccrypt.[ch].
1588 * The same thing was done to silc_hash_* as for silc_cipher_*
1589 routines. Affected files lib/silccrypt/silchash.[ch].
1591 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1592 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1593 Added also silc_pkcs_[un]register[_default] functions.
1594 Removed the data_context from the PKCS API.
1596 * Added silc_hmac_register_default function to register default
1597 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1598 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1599 to unregister all hmacs at once.
1601 * Register the default ciphers, hash functions, PKCSs and HMACs
1602 if client's configuration file does not exist. The affected
1605 * The client did not load the hash functions from the SIM
1606 modules at all. Added support for this. Affected file is
1607 silc/clientconfig.c.
1609 * When decoding public key with silc_pkcs_public_key_decode, check
1610 the supported algorithm only if PKCS are registered. Affected
1611 file lib/silccrypt/silcpkcs.c. The same was done with the
1612 silc_pkcs_private_key_decode.
1614 * Fixed the SILC List routines to keep the list always in order.
1615 It used to change the list's order when traversing the list but
1616 not it preserves the order. Affected file lib/trq/silclist.h.
1618 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Added the client library to use the SilcSocketConnection's
1621 reference counter (by silc_socket_dup) to prevent the bug that
1622 the socket object may be freed underneath async operation.
1624 * The name resolv library checking fixes in the configure.in.pre.
1627 * Created new version of the protocol drafts for future
1628 development. The -03 drafts are the ones that will be changed
1629 in the trunk now and the -02 will remain as they are.
1631 * Send list of CUMODE notifys to the router when announcing
1632 the channel users to the router. Affected file silcd/server.c.
1633 If the router receiving channel founder CUMODE for a channel
1634 that already has channel founder it will send CUMODE notify
1635 to the sender to remove the channel founder rights from the
1636 announced client. Affected file silcd/packet_receive.c.
1638 * The CUMODE notify may now use Server ID as well as the entity
1639 who changes the mode. Updated protocool specs.
1641 * Updated INSTALL and README files.
1643 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * New web pages in the http://silc.pspt.fi. The pages was
1650 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Implemented the [DenyConnectin] config section in the server.
1653 Added silc_server_config_denied_conn to check whether incoming
1654 connection is denied. Affected file silcd/serverconfig.[ch].
1656 * Do not check the ports when checking the incoming configuration
1657 data if the port is 0, meaning any. Affected file is
1658 silcd/serverconfig.c.
1660 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Fixed buffer overflow in silc_string_compare in the file
1663 lib/silcutil/silcutil.c.
1665 * Fixed double free in silc_server_command_leave in the file
1668 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Fixed the version checking in the server. Affected file is
1673 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1675 * Fixed the configuration data fetching when accepting new
1676 connections in the server. Affected file silcd/server.c.
1678 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1680 * Added `sender_entry' argument to the function
1681 silc_server_packet_relay_to_channel so that we can check
1682 whether some destination actually belongs to the same route
1683 the sender belongs (ie, we must not resend the packet to the
1684 sender). Affected file silcd/packet_send.[ch].
1686 * Added `servername' field to the SilcClientEntry in the server
1687 to hold the name of the server where client is from. Affected
1688 file is silcd/idlist.h.
1690 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * Moved the channel message encrypting in the router betwen
1693 router connections from silc_server_channel_message to the
1694 silc_server_packet_relay_to_channel since we want to check
1695 whether we have anybody channel before encrypting anything.
1696 Affected files silcd/packet_[receive/send].c.
1698 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Fixed the [AdminConnection] server config section to support
1701 multiple entries. Affected file silcd/serverconfig.c.
1703 * Added support into the server to check the validity of the
1704 incoming connection before executing any KE or authentication
1707 * The connection configuration is now saved to the KE and
1708 connection auth protocol contexts and not fetched anymore in
1709 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1711 * The local hosts listenning address and port is also resolved
1712 now when starting the server. We want to have the socket object
1713 to include the real address and port for the listener. Added
1714 new function silc_net_check_local_by_sock into the files
1715 lib/silcutil/silcnet.[ch].
1717 * Fixed a broadcast bug in server -> do not broadcast if we
1720 * Fixed a routing bug. Do not route broadcast packets ever.
1721 Broadcast packets must be processed always and not routed since
1722 they may be destined to some other host than yourself and thus
1723 would get routed without no good reason. Affected file is
1726 * Added function silc_server_config_is_primary_route to check
1727 whether primary router connection has been configured (a router
1728 configuration that we are initiating). If there is not, we
1729 will assume that there is only two routers in the SILC network
1730 and we will use the incoming router connection as our primary
1731 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1733 * Changed the order of the broadcasting. Broadcast _after_ the
1734 packet has been processed not before. Affected file is
1737 * Fixed a [ClientConnection] parsing bug. The port was never
1738 parsed correctly thus resulting to port 0. Affected file
1739 silcd/serverconfig.c.
1741 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1742 argument and did not set the broadcast packet flag. Affected
1743 file silcd/packet_send.c. Fixed same bug in the function
1744 silc_server_send_notify as well.
1746 * If we receive NEW_ID packet for our own ID in the server, ignore
1749 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Removed the nickname from the Private Message Payload.
1754 Updated the code and the protocol specs.
1756 * Updated protocol specs for submitting to the IETF.
1758 * Tweaked the Random Number Generator a bit. Affected file
1759 lib/silccrypt/silcrng.c. Exported a new function
1760 silc_rng_[global]_add_noise which can be used to add more
1763 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1765 * Do not parse packets with different timeout when protocol
1766 is active -> may cause problem with rekey. Affected file
1769 * When server receives signoff notify it must not create
1770 new channel key if the client is on any channels since the
1771 sender of the signoff notify will create it.
1773 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Added printing of error messages during SKE protocol from the
1776 failure packet sent by server during SKE. Affected file
1779 * Removed the client's failure_callback handling with timeout
1780 and handle it immediately when received.
1782 * The SKE library returned wrong type in SUCCESS and FAILURE
1783 packets. They must be 32 bit MSB not 16 bit MSB.
1785 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * Ok, rewrote the logic of the re-key and now it seems to work.
1788 I tested it on high traffic with frequent re-keys without
1789 problems. Added hmac_receive (and renamed hmac to hmac_send)
1790 in SilcClientConnection in lib/silcclient/client.h and
1791 in SilcIDListData in silcd/idlist.h. Also, removed the
1792 SilcPacketParserContext's cipher and hmac fields as they are
1793 not needed anymore and actually caused some problems when
1794 the ciphers and hmac's changed underneath the packet parser.
1796 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * If re-key protocol is active then process the incoming packets
1799 synchronously since we must assure that icoming packets encrypted
1800 with the old key is processed before the new keys is set to
1801 use. This is true other packets than for REKEY packets.
1802 Affected file silcd/server.c. The same was done to client library
1803 as well, affected file lib/silcclient/client.c.
1805 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * Fixed bug in client and server to accept the force send if
1808 the packet is send from silc_[server/client]_packet_process
1809 function. Otherwise the packets are never delivered, oops.
1811 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Disable force sending of packets when REKEY protocol is active.
1814 We must assure that no packet is sent directly when rekey is
1815 performed. All packets must be sent through packet queue.
1816 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1817 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1818 function is silc_[server/client]_packet_send_real to check
1821 * Replaced the SIM paths from example config files to
1822 /usr/local/modules. Also, make install creates now
1823 /usr/local/silc/logs directory to hold all the SILC server
1826 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1828 * Made the configure.in.pre work on Solaris. Patch by salo.
1830 * Made all ciphers compatible with non-x86 machines. Defined
1831 CBC mode macros into lib/silccrypt/ciphers_def.h.
1833 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Fixed the make install.
1837 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * When MAC computation fails the silc_packet_decrypt returned 0
1840 even though it was supposed to return -1. Fixed this. The
1841 affected file is lib/silccore/silcpacket.c.
1843 * Do not replace the config files in /etc/silc (in make install)
1844 if they already exist. Affected file ./Makefile.am.
1846 * Do not send re-key packets immediately but through packet queue.
1847 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1849 * Changed silc_net_check_host_by_sock to return FALSE if the
1850 IP/DNS could not be resolved. Though, it returns the IP address
1851 now even if it could not resolve it (but returns also FALSE).
1852 Affected file lib/silcutil/silcnet.[ch].
1854 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Added silc_pkcs_decode_identifier to decode the public key's
1857 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1858 Added also silc_pkcs_free_identifier. Added also new context
1859 SilcPublicKeyIdentifier.
1861 * Added -S option to the silc client. It is used to dump the
1862 contents of the specified public key file.
1864 * Changed the PKCS api to return the public key length when
1865 setting the public key.
1867 * Fixed a fatal bug in the public and private key file loading.
1868 Affected file lib/silccrypt/silcpkcs.c.
1870 * Execute the packet parsing for client with zero (0) timeout
1871 if the protocol is active. Affected file silcd/server.c.
1873 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1875 * Made the key generation options to the silcd program. Added
1876 -C option, equivalent to client's option.
1878 * Added new [ServerKeys] config section to the server. It
1879 configures the server's public and private key.
1881 * Defined generic Public Key Payload into the protocol
1882 specification to send specific type of public keys and
1885 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1886 public key or certificate.
1888 * Implemented the GETKEY command to the server and to the
1889 client library and on user interface.
1891 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Made preliminary `make install' work.
1895 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added SilcServerRekey context into silcd/idlist.h.
1899 * Added the PFS support as defined in the specification to the
1900 SKE protocol. Affected files lib/silcske/*.c.
1902 * Added `ske_group' field to the SilcServerRekey context to hold
1903 the number of the SKE group that is used with PFS in re-key.
1904 Affected file silcd/idlist.h.
1906 * Added PFS re-key support to the server. Affected file is
1909 * Added silc_protocol_cancel to cancel execution of the next
1910 state of the protocol. Affected file is
1911 lib/silccore/silcprotocol.[ch].
1913 * Added the re-key support with and without PFS to the client
1914 library. Re-key is performed once in an hour, by default.
1916 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1917 Added silc_client_rekey_callback and silc_client_rekey_final.
1918 Affected files are lib/silcclient/protocol.[ch] and
1919 lib/silcclient/client.[ch].
1921 * Removed the `hmac_key' and `hmac_key_len' fields from the
1922 SilcClientConnection structure; not needed. Affected file is
1923 lib/silcclient/client.h.
1927 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Do not ask whether user wants to use the negotiated private key
1930 for private messages, just use it. Affected file is
1931 silc/local_command.c.
1933 * Added `send_enc_key' and `enc_key_len' fields to the
1934 SilcIDListData structure since they are needed in the re-key
1935 phase. Affected file is silcd/idlist.[ch].
1937 * Implemented the simple re-key protocol into the server.
1938 Affected files silcd/server.c and silcd/protocol.[ch]. The
1939 re-key will be performed once in an hour, by default.
1941 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1942 Added silc_server_rekey, silc_server_rekey_callback and
1943 silc_server_rekey_final.
1945 * Removed Tunneled flag from the protocol. Updated the code
1946 and the specifications.
1948 * Adde `pfs' field to the SilcIDListData to indicate whether
1949 the PFS is to be performed in the re-key. Affected file is
1952 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1954 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1955 int64 of at least the xintXX size. If void * is less that 4
1956 bytes uint32 * will be used. Defined bool as boolean.
1958 * Changed _ALL_ unsigned long and unsigned int to uint32,
1959 unsgined short to uint16 in the source tree.
1961 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1962 not handle clients that has entry->data.registered == FALSE.
1963 They are not in the network anymore. Affected file is
1966 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Implemented the sending of the SERVER_SIGNOFF notify in the
1969 server. Affected file is silcd/server.c.
1971 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1972 Added also silc_notify_payload_encode_args into the
1973 lib/silccore/silcnotify.[ch].
1975 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1976 Affected file silcd/packet_receive.c.
1978 * Implemented the SERVER_SIGNOFF notify handling in the client
1979 library. Affected file lib/silcclient/client_notify.c. Also,
1980 implemnted the printing of the SERVER_SIGNOFF info to the
1981 application. Affected file silc/client_ops.c.
1983 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1984 if the deleting was successful. Affected file silcd/idlist.[ch].
1986 * Added support for public key authentication in the connection
1987 authentication protocol in the client library. Affected file
1988 lib/silcclient/protocol.c.
1990 * Changed the server's silc_idlist_get_clients_by_* interface
1991 to support already allocated array so that new entries may be
1992 added to pre-allocated array. Affected file silcd/idlist.[ch].
1993 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1994 and command replies.
1996 * All command reply functions in the server now calls the
1997 pending command callback even if error occured. This way the
1998 error will be delivered to the client as well. Affected files
1999 silcd/command.c and silcd/command_reply.c.
2001 * Fixed INFO command to return local server's info if no server
2002 was provided. Affected file lib/silcclient/command.c.
2004 * Removed RESTART command for good. Updated the code and the
2007 * Rewrote parts of the task system. It is a bit simpler now.
2008 Removed unsued task priorities. The affected files are
2009 lib/silcutil/silctask.[ch].
2011 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Moved the USERS printing from the library to the application.
2014 Affected files lib/silcclient/command.c and silc/client_ops.c.
2016 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Added channel key re-key support. The re-key is perfomed
2021 only by the router and is done once in an hour. Added `rekey'
2022 field to the SilcChannelEntry in the server. Affected files
2023 silcd/server.c and silcd/idlist.h.
2025 * Added silc_task_unregister_by_context into the file
2026 lib/silcutil/silctask.[ch].
2028 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Added SILC_UMODE_GONE mode to indicate when the client is not
2031 present in the SILC network. Added also support to the local
2032 command AWAY that will set this mode. Added support of showing
2033 "xxx is gone" in WHOIS command. The USERS command shows the
2034 gone status as well.
2036 * Fixed setting server and router operator privileges in the
2037 server's UMODE command. Affected file silcd/command.c.
2039 * Merged the SKE KE1 and KE2 payloads into one payload. The
2040 new KE payload is equivalent to the old KE2 payload.
2042 Cleaned up the SKE Start Payload parsing. It now uses the
2043 simple buffer unformatting to do the parsing. A lot faster
2046 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2047 to the SKE that is used to indicate whether both of the SKE
2048 parties should perform authentication. By default only the
2049 responder performs authentication. By setting this flag also
2050 the initiator must do authentication. By default it is unset
2051 since in normal SKE case, client to server connection, only
2052 the responder should do authentication. When doing SKE between
2053 two clients both should perform authentication. Updated the
2054 code and the protocol specs.
2056 * A little fix to IDENTIFY command in the server. Search the
2057 client first by hash not nickname. Affected file is
2060 * Fixed the silc_client_close_connection to support closing
2061 the client to client connections wihtout deleting too much
2062 data. Affected file lib/silcclient/client.c.
2064 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2065 are received if protocol used to be active but is not anymore
2066 the application would crash due to NULL pointer dereference.
2067 Affected files silcd/server.c and lib/silcclient/client.c.
2069 * Added `hash' field to the SilcClientConnection to include
2070 the hash function negotiated in the SKE protocol.
2072 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2073 to set the channel founder authentication data. A client can
2074 claim the founder rights later by providing the authentication
2075 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2076 This way the channel founder can regain the channel founder
2077 privileges even it is left the channel. This works only on
2078 local server and the client must be connected to the same
2079 server to be able to regain the founder rights. Updated the
2080 protocol specs accordingly.
2082 Added support to the CMODE command in the client to set the
2083 founder auth data. Read the README to see how to set it.
2085 Added support to the CUMODE command to claim the founder
2086 rights. Read the README to see how to do it.
2088 Added support for the founder authentication to the Channel
2089 Entry in the server. Affected file silcd/idlist.h.
2091 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2092 server's CMODE command. Affected file silcd/command.c.
2094 * Added the following new functions into lib/silccore/silcauth.[ch]:
2095 silc_auth_get_method and silc_auth_get_data.
2097 * The server now saves the remote hosts public key to the
2098 SilcIDListData pointer. Affected file silcd/protocol.c.
2100 * The normal server now does not remove the channel entry from
2101 the cache if the founder authentication data is set. It used
2102 to remove it if the founder was the last one on the channel on
2103 the server and left the channel. The auth data is saved and
2104 if the channel is re-joined later the old entry is used with
2105 the old auth data. Affected files silcd/command_reply.c and
2108 * Removed the `pkcs' field from the SilcIDListData structure
2109 in the server; it is not used. Affected file silcd/idlist.h.
2111 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Fixed packet processing on slow links. Partial packets were
2114 never re-processed because the incoming data buffer was cleared
2115 by the application. Application must not directly clear the
2116 sock->inbuf, the packet processing routines handle it. Fixed
2117 this in client library and in server.
2119 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Fixed the WHOIS and IDENTIFY send reply function to really
2122 check whether to send list or just one entry. Affected file
2125 * Cleaned up the LEAVE command's channel key distribution. The
2126 affected file silcd/command.c.
2128 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2129 can enforce the channel mode as well. In that case the ID
2130 includes the ID of the server. The code now enforces the
2131 mode change if the router have different mode than the server.
2133 * The notify client operation with CMODE_CHANGE notify can now
2134 return NULL client_entry pointer if the CMODE was not changed
2135 by client. Application must check for this.
2137 * Added <Server ID> argument to INFO command to support server
2138 info fetching by Server ID.
2140 * Added silc_server_announce_get_channel_users to get assembled
2141 packets of channel users of the specified channel. Affected
2142 file silcd/server.[ch].
2144 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2145 was freed underneath the ID Cache.
2147 * Re-announce clients when the server received CHANNEL_CHANGE
2148 notify from the router. Affected file silcd/packet_send.c.
2150 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2153 crashed since it did not handle the fact that there is no cipher
2154 called "3" and didn't check the error condition. Now fixed.
2156 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2157 flag. It can be used to send message requests.
2159 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Implemented the RESTART command in the client.
2163 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2164 notice type messages. Added notice printing to the user
2167 * The channel keys are not re-generated if the channel's mode
2168 is PRIVKEY, ie private key on the channel exists. Affected
2169 files silcd/server.c and silcd/command.c.
2171 * Fixed a little bug in channel message delivery when channel
2172 private keys are set in the server. Affected file is
2173 silcd/packet_send.c.
2175 * Changed the setting on channel->on_channel = TRUE from the
2176 silc_client_save_channel_key to the JOIN command reply. The
2177 key payload is not received if the private channel key is set.
2178 Affected file lib/silcclient/command_reply.c and the
2179 lib/silcclient/client_channel.c.
2181 * When the CMODE_CHANGE notify is sent and the channel private
2182 key mode is removed the channel key must be re-generated in
2183 other cells as well. Added this support for the router in the
2184 silcd/packet_receive.c.
2186 * Added new local command NOTICE to send notice message on
2187 channel. Affected file silc/local_command.[ch].
2189 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Added new local command ME to the client. It is used to send
2192 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2193 some action. Affected file silc/local_command.[ch].
2195 * Changed channel_message and private_message client operations
2196 to deliver the message flags to the application. Added also
2197 the `flags' arguments to the silc_client_send_channel_message
2198 and silc_client_send_private_message functions. Affected file
2201 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Redefined the Private Message Payload to support private message
2204 keys and to support the new private message flags. Updated
2205 the protocol specs. Flags makes it possible to have for example
2206 CTCP style messages.
2208 * Added new type SilcPrivateMessagePayload and defined an API
2209 for it in the lib/silcclient/silcprivate.[ch].
2211 * Tested private message private keys successfully. Tested the
2212 private message key set, unset and list commands with the new
2215 * Redefined the Channel Message Payload to include the channel
2216 message flags (equal with private message flags) to support
2217 for example CTCP style messages.
2219 * Defined some of the message (for channel and private message)
2220 flags. Updated the protocol specs and added the flags to the
2221 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2223 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * Added SilcKeyAgreementStatus type to the key agreement routines
2226 to indicate the current status and error if one occured.
2227 The status types are defined in the lib/silcclient/silcapi.h.
2229 * Added new local command KEY that is used to set and unset private
2230 keys for channels, set and unset private keys for private messages
2231 with remote clients and to send key agreement requests and
2232 negotiate the key agreement protocol with remote client. The
2233 key agreement is supported only to negotiate private message keys,
2234 it currently cannot be used to negotiate private keys for channels,
2235 as it is not convenient for that purpose.
2237 * Fixed a minor pending callback setting bug in the function
2238 silc_client_get_client_by_id_resolve, now the function works.
2239 Affected file lib/silcclient/idlist.c.
2241 * Added function silc_net_get_local_port to get local bound
2242 port by socket. Added to lib/silcutil/silcnet.[ch].
2244 * Added `sockets' and `sockets_count' fields to the SilcClient
2245 object. They hold the sockets of the listenning sockets in
2246 the client. Listenning sockets may be for example the key
2247 agreement server. Affected file lib/silcclient/client.[ch].
2248 Added functions the silc_client_add_socket and the
2249 silc_client_del_socket. They are exported to the application
2252 * Added ~./silc/clientkeys to support other client's public keys.
2254 * Renamed verify_server_key client operation to verify_public_key
2255 and added one argument to indicate the type of the connection
2256 (server, client etc.).
2258 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Added silc_server_connection_auth_request to handle the
2261 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2262 silcd/packet_receive.[ch].
2264 * Added silc_server_send_connection_auth_request into the
2265 silcd/packet_send.c to send the connection auth request packet.
2267 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2270 * Fixed the public key authentication in responder side in the
2271 server. The `auth_data' pointer includes the SilcPublicKey
2272 not the path to the public key. Affected file silcd/protocol.c.
2274 * Implemented the public key authentication in the initiator side
2275 in the server. Affected file silcd/protocol.c.
2277 * Removed the [RedirectClient] config section from the server
2278 configuration. Is not needed and I don't want to implement it.
2280 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * Cleaned up the CMODE command in the server. It now works
2283 correctly and supports all the modes defined in the protocol.
2284 Affected file is silcd/command.c.
2286 * Added `hmac_name' field to the SilcChannelEntry in the server
2287 to hold the default HMAC of the channel. It can be set when
2288 creating the channel (with JOIN command). Affected files
2291 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2292 type to indicate the change of the current cipher and hmac
2293 on the channel. Client can safely ignore the <cipher> argument
2294 (if it chooses to do so) since the CHANNEL_KEY packet will
2295 force the channel key change anyway. The <hmac> argument is
2296 important since the client is responsible of setting the new
2297 HMAC and the hmac key into use.
2299 * Fixed the CMODE command in the client library as well.
2301 * Tested CMODE command in router environment successfully.
2303 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Show the version of the remote client (or server) when connecting
2306 to the server. It is logged to the log file. Affected file
2307 is silcd/protocol.c.
2309 * Fixed the KILLED notify handling in the client library. The
2310 client must be removed from all channels when receiving the
2313 Also, do not remove the client entry when giving the KILL
2314 command but when the KILLED notify is received.
2316 * Removed silc_idlist_find_client_by_nickname from the server.
2317 Not needed anymore. Affected files silcd/idlist.[ch].
2319 * Implemented the CHANNEL_CHANGE notify type handling to the
2320 server. Affected file silcd/server.c.
2324 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Added silc_server_send_notify_invite to send the INVITE
2327 notify between routers.
2329 * Implemented the INVITE command correctly to the server.
2331 * Implemented the INVITE notify type handling in the server.
2333 * Implemented the INVITE command to the client library and on the
2336 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Added function silc_server_get_client_resolve to find the
2339 client entry by ID from all ID lists and then resolve it
2340 (using WHOIS) if it cannot be found. Affected file is
2343 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Implemented the BAN command to the client library.
2347 * The JOIN command in the server now checks the invite list
2350 * Changed the silc_command_reply_payload_encode_va and the
2351 silc_command_payload_encode_va to support that if argument is
2352 NULL it ignores and checks the next argument. Affected file
2353 lib/silccore/silccommand.c.
2355 * Added silc_server_send_notify_ban to send the BAN notify
2356 type between routers.
2358 * Chaned the silc_notify_payload_encode to support that if
2359 argument is NULL it ignores and checks the next argument.
2360 Affected file lib/silccore/silcnotify.c.
2362 * Tested ban lists in router environment successfully.
2364 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Implemented BAN command to the server, in silcd/command.[ch].
2368 * Removed the BAN and INVITE_LIST modes from the CMODE command
2371 * Added function silc_string_match to regex match two strings.
2372 Affected files lib/silcutil/silcutil.[ch].
2374 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Redefined parts of the SilcChannelEntry in the server to support
2377 the new ban and invite lists.
2379 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Redefined the INVITE command. The same command can be used to
2382 invite individuals to the channel but also to manage the invite
2383 list of the channel (to add to and remove from the invite list).
2384 Updated the protocol specs.
2386 * Added new command SILC_COMMAND_BAN that can be used to manage
2387 the ban list of the channel. Updated the protocol specs.
2389 * Removed the channel modes: the SILC_CMODE_BAN and the
2390 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2391 in the CMODE command. The equivalent features are now available
2392 using INVITE and BAN commands. Updated the protocol specs.
2394 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2395 in the network about change in the current ban list. The notify
2396 type is not used by the client.
2398 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2399 support the invite lists.
2401 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Added new function silc_string_regexify that converts string
2404 including wildcard characters into regex string that can
2405 be used by the GNU regex library. Added into the file
2406 lib/silcutil/silcutil.[ch].
2408 Added silc_string_regex_combine to combine to regex strings
2409 into one so that they can be used as one regex string by
2410 the GNU regex library. Added into the file
2411 lib/silcutil/silcutil.[ch].
2413 Added silc_string_regex_match to match two strings. It returns
2414 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2416 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Imported GNU regex to the soruce tree into lib/contrib.
2419 Fixed some compiler warning from the regex.c.
2421 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Fixed MOTD command in the server to work in router environment.
2425 * Fixed the MOTD command in the client library to support
2426 the server argument in the command.
2428 * Added `nickname_len' argument to the silc_idlist_add_client
2429 in the server, as the `nickname' argument may be binary data
2432 * Added silc_idlist_get_channels to return all channels from
2435 * Implemented LIST command to the server. Affected file is
2438 * Implemented the LIST command to the client library and on the
2441 * Added [<user count>] argument to the LIST command reply.
2442 With private channels the user count is not shown.
2444 * Updated TODO and README.
2446 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * The client entry's data.registered must be TRUE even with
2449 global client entry on global client list. The data.registered
2450 is used to check whether the client is anymore in the network,
2451 for example with WHOWAS command so it must be valid.
2453 * Fixed the WHOWAS command in the server. It now actually works
2454 in router environment. Added function into silcd/command_reply.c
2455 silc_server_command_reply_whowas_save.
2457 * Added silc_idlist_purge function to the silcd/idlist.c
2458 to periodically purge the ID Cache.
2460 * Fixed INFO command in the server. It works now in router
2461 environment. Added <server name> argument to the INFO command
2462 reply. Updated the protocol specs.
2464 * Fixed minor bug in silc_idcache_purge to not purge if the
2465 expire value is zero.
2467 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2468 they were buggy because of the WHOWAS information.
2470 * Fixed local command MSG to handle the async resolving of
2471 the remote client properly. It used to fail the first MSG.
2472 Affected file silc/local_command.c.
2474 * Added `data_len' field to SilcIDCache context.
2476 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Update TODO. Todo in commands in the server.
2480 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2482 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2483 used by routers as broadcast packet to inform other routers
2484 about the changed user mode.
2486 Implemented the notify handling in the server. Affected file is
2487 silcd/packet_receive.c. Added the function
2488 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2490 * Added new generic Channel Payload and deprecated the New Channel
2491 Payload. The New Channel Payload is now the generic Channel
2494 * Added new argument `mode' to the silc_server_send_new_channel
2495 as it is required in the Channel Payload now.
2497 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2498 and created a new and real SilChannelPayload to represent the
2499 new generic Channel Payload. Implemented the encode/decode
2500 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2502 * Added silc_server_get_client_channel_list to return the list
2503 of channels the client has joined for WHOIS command reply.
2504 Affected file silcd/server.[ch].
2506 * Implemented the channel list sending in the WHOIS command reply
2507 in server and in the client.
2509 Implemented the channel list displaying on the user interface
2510 as well. Affected file silc/client_ops.c.
2512 * Added silc_channel_payload_parse_list to parse list of Channel
2513 Payloads. It returns SilcDList list of SilcChannelPayloads.
2514 Client for example can use this function to parse the list of
2515 channels it receives in the WHOIS command reply. The caller
2516 must free the list by calling silc_channel_payload_list_free.
2517 Affected files lib/silccore/silcchannel.[ch].
2519 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Added one new argument <user mode> to the WHOIS command reply
2522 to return the mode of the user in SILC. Updated the protocol
2525 Implemented it to the server and client.
2527 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Fixed the mode printing on the user interface on joining.
2530 Affected file silc/client_ops.c.
2532 * Implemented the UMODE command and user modes in general to the
2533 client library and to the user interface.
2535 * Implemented the UMODE command to the server.
2537 * The server now sends UNKNOWN_COMMAND error status if client sends
2538 unknown command. Affected file silcd/command.c.
2540 * All server commands now handle the command identifier the right
2541 way when sending the command reply to the client. The client can
2542 use to identify the command replies with the identifier.
2544 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Added silc_server_get_client_route to resolve the route to
2547 the client indicated by the client ID. Affected file is
2550 * Added silc_server_relay_packet as general function to relay
2551 packet to arbitrary destination. This deprecates functions
2552 like _send_private_message_key, _relay_notify etc. Affected
2553 file is silcd/packet_send.[ch].
2555 Removed silc_server_send_key_agreement,
2556 silc_server_send_private_message_key and
2557 silc_server_packet_relay_notify functions from the file
2558 silcd/packet_send.[ch].
2562 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2563 server. Affected file silcd/packet_receive.[ch].
2565 * Implemented the KILL command to the client. Implemented the
2566 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2567 Affected files lib/silcclient/command[_reply].c and
2568 lib/silcclient/client_notify.c. Implemented the KILL notify
2569 printing in the user inteface.
2571 * Fixed a lot silc_parse_nick memory leaks from the client
2572 library in the file lib/silcclient/command.c.
2574 * Changed the silc_server_send_notify_on_channels's `sender'
2575 argument from SilcSocketConnection to SilcClientEntry to
2576 check the sender as entry and not as connection object and not
2577 to send to the client provided as argument. The affected file
2578 is silcd/packet_send.[ch].
2580 * The notify packets that are destined directly to the client used
2581 to not to be processed by the server. Now changed that and the
2582 server processes all notify packets. After relaying the packet
2583 to the client the notify packet is processed in the server.
2585 * The silc_server_free_client_data now checks whether there is
2586 pending outgoing traffic for the client and purges the data to
2587 the network before removing the client entry.
2589 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2592 an client is killed from the SILC Network. Updated the protocol
2595 Added new function silc_server_send_notify_killed to the
2596 silcd/packet_send.[ch].
2598 * Added function silc_server_packet_relay_notify to relay notify
2599 packets that are destined directly to a client. In this case
2600 the server does not process the notify packets but merely relays
2601 it to the client. Affected file silcd/packet_send.[ch].
2603 Added also silc_server_packet_process_relay_notify to check
2604 whereto relay the notify. Affected file is
2605 silcd/packet_receive.[ch].
2607 * Implemented the KILL command to the server.
2611 * Added the backup schema desgined last fall to the protocol
2612 specs for everyone to see. The specification is in the
2613 *-spec-xx.txt draft and the packet type definitions for the
2614 backup routers is in *-pp-xx.txt draft. Thusly, added also
2615 new packet type SILC_PACKET_CELL_ROUTERS.
2617 * A big security problem in the implementation discovered. The
2618 signoff of an client did not cause new channel key generation
2619 which it of course should've done. The channel keys must be
2620 always re-generated when client leaves (or signoffs) the channel.
2621 The silc_server_remove_from_channels funtion now handles
2622 the channel key re-generation.
2624 * Added `sender' argument to the silc_server_send_notify_on_channels
2625 to not to send the client provided as argument. Affected file
2626 silcd/packet_send.[ch].
2628 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Implemented OPER and SILCOPER commands into the server and
2633 * Added silc_auth_verify and silc_auth_verify_data to verify
2634 the authentication directly from the authentication payload.
2635 It supports verifying both passphrase and public key based
2636 authentication. Affected file lib/silccore/silcauth.[ch].
2638 * Added `hash' field to the SilcIDListData structure. It is the
2639 hash negotiated in the SKE protocol. Affected file is
2642 * Slight redesigning of the SilcAuthPayload handling routines.
2643 Do not send SilcPKCS but SilcPublicKey as argument.
2645 * Implemented the public key authentication support to the
2646 serverconfig. The public key is loaded from the provided path
2647 and saved as authentication data to void * pointer. Thus,
2648 changed the unsigned char *auth_data to void *auth_data;
2650 * Fixed SHUTDOWN command to send the reply before the server
2651 is shutdown. :) Affected file silcd/command.c.
2653 * Fixed fatal bug in CONNECT command. The hostname was invalid
2654 memory and server crashed. Affected file silcd/command.c.
2656 * Fixed fatal bug in CLOSE command. The server_entry became
2657 invalid but was referenced later in the command. Affected file
2660 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2662 * Fixed fatal bug in failure packet handling. Server ignored
2663 the failure and thus crashed when it came.
2667 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2670 that the command may be executed only once in (about) 2 seconds.
2671 The old SILC_CF_LAG flag is same but allows command bursts up
2672 to five before limiting.
2674 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2675 server code. Various commands now includes the CF_LAG_STRICT
2676 flag to disallow any kind of miss-use of the command.
2678 * Fixed the silc_buffer_unformat to not to allocate any data
2679 if the length of the data is zero. It used to allocate the
2680 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2682 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * Changed the format of AdminConnection configuration section
2685 in the server. Added username of the admin to the format.
2686 Affected files silcd/serverconfig.[ch].
2688 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2689 to return admin configuration data by host, username and/or
2692 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Implemented WHOWAS command to the server. Added the functions:
2696 silc_server_command_whowas_parse,
2697 silc_server_command_whowas_send_reply,
2698 silc_server_command_whowas_from_client and
2699 silc_server_command_whowas_from_server
2701 * Added <Client ID> argument to the WHOWAS command reply. Updated
2702 the protocol specs accordingly.
2704 * Implemented WHOWAS command and command_reply to the client
2707 Implemented the WHOWAS printing on the user interface.
2709 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Added new argument to the WHOWAS command reply, the real name.
2712 It is an optional argument. Updated the protocol specs.
2714 * Added SilcIDCacheDestructor callback that is registered when
2715 the SilcIDCache is allocated. The callback is called when
2716 an cache entry in the ID Cache expires, or is purged from the
2717 cache. Added into lib/silccore/idcache.[ch].
2719 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2720 to destruct the client entries when the cache entry expires.
2721 Other ID Cache's in server and in the client library ignores
2724 * If the ID Cache entry's `expire' field is zero then the entry
2725 never expires. Added boolean `expire' argument to the
2726 silc_idcache_add function in the lib/silccore/idcache.[ch].
2727 If it is TRUE the default expiry value is used.
2729 * Added silc_server_free_client_data_timeout that is registered
2730 when client disconnects. By default for 5 minutes we preserve
2731 the client entry for history - for WHOWAS command.
2733 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Added support to the server to enforce that commands are not
2736 executed more than once in 2 seconds. If server receives
2737 commands from client more frequently, timeout is registered
2738 to process the commands. Affected file silcd/command.c.
2739 Added new function silc_server_command_process_timeout.
2741 * Changed NICK_NOTIFY handling in client library to check that
2742 if the client's nickname was changed, so there is no need to
2743 resolve anything from the server.
2745 * Removed error printing from the WHOIS and IDENTIFY commands.
2746 If error occurs then it is ignored silently in the client library.
2747 The application, however, may map the received error to
2748 human readable error string. The application currently maps
2749 the NO_SUCH_NICKNAME error to string.
2751 * Made the command status message public to the application. Moved
2752 them from lib/silcclient/command_reply.c to
2753 lib/silcclient/command_reply.h. The application can map the
2754 received command status to the string with the
2755 silc_client_command_status_message function.
2757 * Added check to the server to check that client's ID is same
2758 as the Source ID in the packet the client sent. They must
2761 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Added dist-bzip hook to the Makefile.am to make bzip2
2764 compressed distributions.
2766 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Server now enforces the maximum length for the nickname and
2769 the channel as protocol specification dictates. 128 bytes for
2770 nickname and 256 bytes for channel name.
2772 * Moved the WHOIS printing to the application. The client libary
2773 does not print out the WHOIS information anymore, the application
2774 must do it. Renamed silc_client_command_reply_whois_print to
2775 the silc_client_command_reply_whois_save.
2777 The client's idle time is also sent to the application now, and
2778 the idle is shown on screen.
2780 * Added silc_client_command_reply_identify_save to save the
2781 received IDENTIFY entries.
2783 * Do not check for channel private keys in message sending and
2784 reception if the channel does not have the PRIVKEY mode set.
2785 Affected file lib/silclient/client_channel.c.
2787 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2790 just surfaced after chaning the JOIN procedure.
2792 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Added silc_client_get_clients_by_list to get client entries
2795 from Client ID list, that is returned for example by JOIN
2796 and USERS command replies. The application should use this
2797 function for example when JOIN command reply is received to
2798 resolve the clients already on the channel (library does not
2799 do that anymore as USERS command reply is not used in the JOIN
2800 procedure anymore). Affected files lib/silcclient/silcapi.h and
2801 lib/silcclient/idlist.c.
2803 * JOIN command reply and USERS command reply returns now SilcBuffer
2804 pointers instead of unsigned char pointers when returning
2805 the client list and mode list.
2807 * Added <Client ID> argument to the JOIN command reply, mainly
2808 for the server to identify for which client the command was
2809 originally sent. Updated protocol specs accordingly.
2811 * Added SilcDlist private_key pointer to the SilcChannelEntry
2812 in the client to support the channel private keys. Affected
2813 file is lib/silcclient/idlist.h.
2815 * Added SilcChannelPrivateKey argument to the function
2816 silc_client_send_channel_message so that application can choose
2817 to use specific private ke if it wants to. If it is not provided,
2818 the normal channel key is used, unless private keys are set.
2819 In this case the first (key that was added first) is used
2820 as the encryption key.
2822 * Implemented the support for channel private key handling.
2823 Implemented the following functions:
2825 silc_client_add_channel_private_key,
2826 silc_client_del_channel_private_keys,
2827 silc_client_del_channel_private_key,
2828 silc_client_list_channel_private_keys and
2829 silc_client_free_channel_private_keys
2831 Affected file lib/silcclient/client_channel.c.
2833 * Added the support for the private keys in the channel message
2834 sending and encryption and in the message reception and
2835 decryption. Affected funtions are
2836 silc_client_send_channel_message and silc_client_channel_message.
2838 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added SKE's key verify callback to the client library's
2841 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2843 * Removed the statement that server (or router) must send USERS
2844 command reply when joining to the channel so that the client
2845 knows who are on the channel. Instead, the client list and
2846 client's mode list is now sent in the JOIN command reply to the
2847 client who joined channel. This is better solution.
2849 * Added function silc_server_get_users_on_channel and function
2850 silc_server_save_users_on_channel to the silcd/server.[ch].
2852 * Removed function silc_server_command_send_users from the
2855 * Do not show topic on the client library anymore. The topic is
2856 sent in the command reply notify to the application and the
2857 application must show the topic now.
2859 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Added client searching by nickname hash into the IDENTIFY and
2862 WHOIS commands in the server as they were clearly missing from
2863 them. Affected file is silcd/command.c.
2865 * Fixed a bug in private message receiving in the client library.
2866 The remote ID was freed and it wasn't supposed, now it is
2869 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Minor fix to the channel payload; allocate the data area, as it
2872 needs to be of specific length.
2874 * If the key agreement port is zero then the operating
2875 system will define the bound port. Affected files are
2876 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2878 * Added new function silc_channel_payload_decrypt into the file
2879 lib/silccore/silcchannel.[ch].
2881 * Moved the channel message etc, check from silc_packet_decrypt
2882 to applications. The library calls now a generic
2883 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2884 when the packet is either normal or special. This was done to
2885 allow more wide range of checking that was not allowed when
2886 the code was in library. Now applications can do virtually any
2887 checks to the packet and return to the library the decision how
2888 the packet should be processed. Affected files are
2889 lib/silccore/silcpacket.[ch].
2891 Added silc_server_packet_decrypt_check to the server and
2892 silc_client_packet_decrypt_check to the client library.
2894 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2895 to send with specified source and destination information.
2897 * Channel message delivery between routers was broken after the
2898 channel key distribution was fixed earlier. The channel key
2899 was used be to distributed to other routers as well which is not
2900 allowed by the protocol. Now this is fixed and channel keys
2901 really are cell specific and the channel message delivery between
2902 routers comply with the protocol specification.
2904 * Fixed various commands in server to check also the global list
2905 for the channel entry and not just the local list. The affected
2906 file silcd/command.c.
2908 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added assert()s to buffer formatting and unformatting routines
2911 to assert (if --enable-debug) when error occurs. Affected
2912 file: lib/silcutil/silcbuffmt.c.
2914 * Changed to auto-reconnect to check whether the remote host is
2915 router and register the re-connect timeout if it is. It used
2916 to check that whether we are normal server, but router must do
2917 auto-reconnect with another router as well. Affected file
2920 * Removed the [<key len>] option from CMODE command as the cipher
2921 name decides the key length, nowadays. See the defined ciphers
2922 from the protocol specification.
2924 * Added [<hmac>] option to the CMODE command to define the HMAC
2925 for the channel. Added SILC_CMODE_HMAC channel mode.
2927 * Added [<hmac>] option for the JOIN command so that user can
2928 select which HMAC is used to compute the MACs of the channel
2931 * Added Hmac field to the Channel Message Payload. The integrity
2932 of plaintext channel messages are now protected by computing
2933 MAC of the message and attaching the MAC to the payload. The
2934 MAC is encrypted. Now, it is clear that this causes some
2935 overhead to the size of the packet but rationale for this is that
2936 now the receiver can verify whether the channel message decrypted
2937 correctly and also when private keys are set for the channel the
2938 receiver can decrypt the packet with several keys and check from
2939 the MAC which key decrypted the message correctly.
2941 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2942 lib/silccrypt/silccipher.[ch].
2944 * Added silc_hash_len to return the digest length into the
2945 lib/silcrypt/silchash.[ch].
2947 * Rewrote parts of Silc Channel Payload interface in the
2948 lib/silccore/silcchannel.[ch]. The encode function now also
2949 encrypts the packet and parse function decrypts it.
2951 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Fixed a minor formatting bug in the SKE's key material processing.
2954 It actually might have processed the keys wrong way resulting
2957 * Redefined the mandatory HMAC algorithms and added new algorithms.
2958 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2959 and hmac-md5 truncated to 96 bits. The mandatory is now
2960 hmac-sha1-96. Rest are optional (including the one that used
2961 to be mandatory). Rationale for this is that the truncated HMAC
2962 length is sufficient from security point of view and can actually
2963 make the attack against the HMAC harder. Also, the truncated
2964 HMAC causes less overhead to the packets. See the RFC2104 for
2967 * Added new [hmac] configuration section. The SKE used to use
2968 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2969 is of course wrong. The official names that must be proposed in
2970 the SKE are the ones defined in the protocol specification
2971 (hmac-sha1-96 for example). The user can configure any hmac
2972 using any hash function configured in the [hash] section. At
2973 least, the mandatory must be configured.
2975 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2977 * Added HMAC list to the SKE proposal list. It has now both
2978 hash algorithm list and HMAC list. This makes the protocol
2979 incompatible with previous versions. The SKE now seems to work
2980 the way it is supposed to work, for the first time actually.
2982 * Defined plain Hash algorithms to the protocol specification.
2985 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Implemented support for key agreement packets into the server.
2988 Added functions silc_server_key_agreement and
2989 silc_server_send_key_agreement. Other than these functions,
2990 server has nothing to do with this packet.
2992 * Added support for private message key packets into the server.
2993 Added functions silc_server_private_message_key and
2994 silc_server_send_private_message_key.
2998 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2999 called in the protocol's final callback instead in the END
3000 protocol state. This makes a little more sense and in the same
3001 time in client we can use the same protocol routines for normal
3002 key exchange and to key agreement packet handling as well.
3004 * Added to both client's and server's KE protocol context the
3005 SilcSKEKeyMaterial pointer to save the key material. We will
3006 bring the key material to the protocol's final callback by doing
3007 this. The final callback must free the key material.
3009 * Added SKE's packet_send callback into client's KE protocol
3010 context so that the caller can choose what packet sending function
3011 is used. This way we can use different packet sending when
3012 doing normal SKE when doing key agreement packet handling (in
3013 the key agreement packet handling we do not want to encrypt
3016 * Implemented the responder side of the key agreement routines
3017 in the client. The client can now bind to specified port and
3018 accept incoming key negotiation. The key material is passed
3019 to the application after the protocol is over.
3021 * Implemented the processing of incoming Key Agreement packet
3022 in the client. Added function silc_client_key_agreement to
3025 * Implemented the intiator side of the key agreement routines
3026 in the client. The client can now initiate key agreement with
3027 another remote client. The key material is passed to the
3028 application after the protocol is over.
3030 * Created client_keyagr.c to include all the key agreement
3033 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3034 SILC_TASK_CALLBACK except that it is not static.
3036 * Created client_notify.c and moved the Notify packet handling
3037 from the client.[ch] into that file.
3039 * Created client_prvmsg.c and moved all private message and
3040 private message key routines from the client.[ch] into that file.
3042 * Create client_channel.c and moved all channel message and
3043 channel private key routines from the client.[ch] into that file.
3045 * Changed silc_client_get_client_by_id_resolve to resolve with
3046 WHOIS command instead of IDENTIFY command, in the file
3047 lib/silclient/idlist.c.
3049 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Implemented the SKE's responder side to the Client library.
3053 * When FAILURE is received to the protocol do not trust it
3054 blindly. Register a timeout to wait whether the remote closes
3055 the connection as it should do it, only after that process the
3056 actual failure. This was changed to both client and server.
3058 * Added client_internal.h to include some of the structures
3059 there instead of client.h in lib/silcclient/.
3061 * Added function silc_task_unregister_by_callback to unregister
3062 timeouts by the callback function.
3064 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Some "Incomplete WHOIS info" errors has been appearing on the
3067 log files. Took away the entry->userinfo check from WHOIS
3068 reply sending. The entry->userinfo is now " " if client did not
3069 provide one. I thought this was fixed earlier but something
3070 is wrong still. Let's see if the error still appears.
3072 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Fixed a minor bug in the login when the channel key is
3075 re-generated in the server. It used to generate the key in
3076 wrong order and thus caused problems in the channel traffic.
3078 * Fixed a minor bug in channel key distsribution after
3079 KICK command. The key was not sent to the router even though
3082 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Added silc_ske_process_key_material_data as generic routine
3085 to process any key material as the SILC protocol dictates. The
3086 function is used by the actual SKE library but can be used by
3087 applications as well. This relates to the private message keys
3088 and the channel private keys since they must be processed the
3089 same way the normal SILC session keys. The protocol dictates
3090 this. Affected files: lib/silcske/silcske.[ch].
3092 Added also silc_ske_free_key_material to free the
3093 SilcSKEKeyMaterial structure.
3095 * Defined silc_cipher_set_key function to set the key for
3096 cipher without using the object's method function. The affected
3097 files: lib/silccrypt/silccipher.[ch].
3099 * Implemented silc silc_client_add_private_message_key,
3100 silc_client_add_private_message_key_ske,
3101 silc_client_del_private_message_key,
3102 silc_client_list_private_message_keys and
3103 silc_client_free_private_message_keys functions in the
3106 Added functions silc_client_send_private_message_key to send
3107 the Private Message Key payload and silc_client_private_message_key
3108 to handle incoming Private Message Key payload.
3110 * Added Cipher field to the Private Message Key payload to set
3111 the cipher to be used. If ignored, the default cipher defined
3112 in the SILC protocol (aes-256-cbc) is used.
3114 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Removed lib/silcclient/ops.h file.
3118 Redefined parts of the SILC Client Library API. Created new
3119 file silcapi.h that deprecates the ops.h file and defines the
3120 published Client Library API. Defined also private message key
3121 API and channel private key API into the file.
3123 This is the file that the application must include from the
3124 SILC Client Library. Other files need not be included by
3125 the application anymore.
3127 * Added new key_agreement client operation callback and also
3128 defined the Key Agreement library API for the application.
3130 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3133 is used by clients to request key negotiation between another
3134 client in the SILC network. If the negotiation is started it
3135 is performed using the SKE protocol. The result of the
3136 negotiation, the secret key material, can be used for example
3137 as private message key.
3139 Implemented the Key Agreement payload into the files
3140 lib/silccore/silauth.[ch].
3142 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Redefined ciphers for the SILC protocol. Added some new ciphers
3145 and defined the key lengths for the algorithms. Changed the
3146 code accordingly. The default key length is now 256 bits.
3148 * Fixed SKE key distribution function silc_ske_process_key_material
3149 when the key length is more than 128 bits. The default key
3150 length in SILC is now 256 bits.
3152 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3153 to indicate unsupported algorithm.
3155 * Renamed rijndael.c to aes.c and all functions as well.
3157 * Fixed a long standing channel key setting bug in client library.
3158 Weird that it has never surfaced before.
3160 * Fixed bug in channel deletion. If the entire channel is removed
3161 then it must also delete the references of the channel entry
3162 from the client's channel list as the client's channel entry and
3163 the channel's client entry share same memory.
3165 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Implemented CONNECT and SHUTDOWN commands in the client.
3169 * Implemented CLOSE command to the client.
3171 * Added the function silc_idlist_find_server_by_name into the
3172 files silcd/idlist.[ch].
3174 Added the function silc_idlist_find_server_by_conn into the
3175 files silcd/idlist.[ch].
3177 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * DIE command was renamed to SHUTDOWN. Updated the both code
3182 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3183 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3185 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3188 * Added function silc_server_create_connection function to create
3189 connection to remote router. My server implementation actually
3190 does not allow router to connect to normal server (it expects
3191 that normal server always initiates the connection to the router)
3192 so the CONNECT command is only good for connecting to another
3195 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3198 or some other client was kicked from the channel.
3200 Implemented the handling of the notify type to both client
3203 Implemented silc_server_send_notify_kicked to send the KICKED
3204 notify. It is used to send it to the server's primary router.
3206 * Implemented the KICK command into server and client.
3208 * Added `query' argument to the silc_idlist_get_client function
3209 to indicate whether to query the client from server or not if
3212 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3213 to indicate that the client is not channel founder.
3217 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Removed the rng context from SilcPacketContext structure and
3220 changed that the packet routine uses the Global RNG API.
3222 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added support for quit message that client can "leave" on the
3225 channel when it quits the SILC. It is ditributed inside the
3226 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3228 Added silc_server_free_client_data that will take the
3229 signoff message as argument.
3231 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3233 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Updated parts of the protocol specification to keep it up
3238 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3241 payloads in one packet.
3243 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3244 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3245 use now the new List flag.
3247 * Also deprecated the following packet types: REPLACE_ID,
3248 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3250 * Added list support for Notify packet in server.
3252 * Added silc_server_send_notify_channel_change to send the
3253 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3254 the silc_server_send_replace_id.
3256 * Added silc_server_send_notify_nick_change to send the
3257 NICK_CHANGE notify type. Deprecates the function
3258 silc_server_send_replace_id.
3260 * Added silc_server_send_notify_join to send the JOIN notify type.
3261 Deprecates the function silc_server_send_new_channel_user.
3263 * Added silc_server_send_notify_leave to send LEAVE notify type.
3264 Deprecates the function silc_server_send_remove_channel_user.
3266 * Added silc_server_send_notify_cmode and
3267 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3268 types. Deprecates the silc_server_send_set_mode function.
3270 * Added SERVER_SIGNOFF notify type to indicate that server has
3271 quit. This means that all clients on the channel from that
3272 server will drop. This can be also used when netsplit happens.
3274 Deprecated REMOVE_ID packet type since it is not needed anymore
3277 Added silc_server_send_notify_server_signoff to send the
3278 SERVER_SIGNOFF notify type. Deprecates the function
3279 silc_server_send_remove_id.
3281 Added also silc_server_send_notify_signoff to send the
3282 SIGNOFF notify type.
3284 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3285 SILC protocol from this day on. Changed the protocol
3286 specification as well.
3288 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3289 notify type. It is used between routers to notify about
3290 topic changes on a channel.
3292 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3295 * Partly updated the protocol specification to comply with the
3296 changes now made. It is still though a bit outdated.
3298 * The JOIN notify type now takes one extra argument <Channel ID>.
3299 The packet used to be destined to the channel but now the
3300 JOIN type may be sent as list thus it is impossible to
3301 destine it to any specific channel. By adding this argument
3302 it is again possible.
3304 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added CREDITS file. The CHANGES and CREDITS file will appear
3307 in the distribution as well.
3309 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3312 types in the server's silcd/packet_receive.c.
3314 * Implemented CMODE and CUMODE to work in router environment.
3316 * Fixed minor encoding and decoding buglet from the
3317 lib/silccore/silcmode.c.
3319 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3322 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3324 * Changed all SilcConfigServer* and silc_config_server* to
3325 SilcServerConfig* and silc_server_config*, respectively.
3328 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Associated the ID (client or server ID) to the Authentication
3331 Payload to avoid any possibility of forging. Updated the
3332 protocol specification and the code accordingly.
3334 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * The RSA key length is now save to the RsaKey context in the
3337 key generation process in lib/silccrypt/rsa.c. The key length
3338 is now used to figure out the maximum size of the block allowed
3339 to be encrypted/signed.
3341 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3342 is equivalent to the silc_mp_mp2bin but does not allocate any
3345 * Changed silc_mp_mp2bin API to take length argument. If it is
3346 non-zero then the buffer is allocated that large. If zero, then
3347 the size is approximated using silc_mp_sizeinbase, which however
3350 * Created Global RNG API which is global RNG that application can
3351 initialize. After initializing, any routine anywhere in the
3352 code (including library) can use RNG without allocating a new
3353 RNG object. This was done to allow this sort of use of the
3354 RNG in code that has no chance to allocate RNG object. All
3355 applications currently allocate this and many routines in the
3356 library use this. Affected file lib/silccrypt/silcrng.[ch].
3358 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3359 it to use the Global RNG API.
3361 * Defined Authentication Payload into protocol specification that
3362 is used during SILC session to authenticate entities. It is
3363 used for example by client to authenticate itself to the server
3364 to obtain server operator privileges.
3366 Implemented this payload into the lib/silccore/silcauth.[ch].
3367 Implemented also routines for public key based authentication
3368 as the new protocol specification dictates.
3370 Moved definitions of different authentication methods from
3371 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3373 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3374 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3375 silc_pkcs_verify_with_hash functions into the file
3376 lib/silccrypt/silcpkcs.[ch].
3378 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * The client entry's userinfo pointer must be always valid.
3381 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3382 will fail since it requires the userinfo. Now, the userinfo
3383 is allocated as "" if actual userinfo does not exist. Actually,
3384 it must exist and it is totally Ok to drop client connections
3385 that does not announce the userinfo. However, we will make
3386 this workaround for now.
3388 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3389 to return the remote port by socket.
3391 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3394 SILC_SERVER_PENDING_EXEC and added an new macro
3395 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3396 data or when error occurs while processing the pending command.
3398 Added new argument `destructor' into silc_server_command_pending
3399 and to the SilcServerCommandPending object. This destructor is
3400 now called after calling the pending callback or if error occurs
3401 immediately. If error occurs the actual pending callback won't
3402 be called at all - only the destructor. The destructor may be
3403 NULL if destructor is not needed.
3405 All this applies for client library code as well. Similar
3406 changes were made there as well for the pending commands.
3408 In the client, the application must now allocate the
3409 SilcClientCommandContext with the silc_client_command_alloc
3412 * Added reference counter to the SilcServerCommandContext. Added
3413 function silc_server_command_alloc and silc_server_command_dup
3416 Same type of functions added to the client library for the same
3419 * Removed the cmd_ident from IDListData away since it is now
3420 global for all connections. It is the command identifier used
3421 in command sending and with pending commands. The affected file
3424 * Added reference counter to the SilcSocketConnection objecet to
3425 indicate the usage count of the object. The object won't be
3426 freed untill the reference counter hits zero. Currently only
3427 server uses this, and client ignores it. The client must be
3428 set to use this too later. The affected files are
3429 lib/silccore/silcsockconn.[ch]. Added also the function
3430 silc_socket_dup to increase the reference counter.
3432 This was mainly added because it is possible that the socket
3433 is removed underneath of pending command or other async
3434 operation. Now it won't be free'd and proper DISCONNECTING
3435 flags, etc. can be set to avoid sending data to connection that
3436 is not valid anymore.
3438 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3439 the connection. After that it sets SILC_SET_DISCONNECTED.
3440 It is, however, possible that the socket data is not still freed.
3441 The silc_server_packet_process now checks that data is not
3442 read or written to connection that is DISCONNECTED. The socket
3443 get's freed when the reference counter hits zero.
3445 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Changed the client operation API: channel_message operation's
3448 `sender' is now the client entry of the sender, not the nickname
3449 and the `channel' is the channel entry, not the channel name.
3451 In the private_message operation the `sender' is now also the
3452 client entry of the sender not the nickname.
3454 Affected file is lib/silcclient/ops.h and all applications
3455 using the client operations.
3457 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Moved the calling of ops->connect() from connect_to_server_final
3460 into receive_new_id functin since that is the point when the
3461 client is actually allowed to send traffic to network. The
3462 affected file is lib/silcclient/client.c.
3464 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3467 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3468 (if needs broadcasting) instead of broadcasting the packets one
3469 by one which would make a burst in the network traffic.
3471 * Added `broadcast' argument to the functions in silcd/server.[ch]
3472 silc_server_create_new_channel[_with_id] to indicate whether
3473 to send New Channel packet to primary router.
3475 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Added new function into the silcd/server.[ch] files:
3478 silc_server_create_new_channel_with_id to create new channel with
3479 already existing Channel ID.
3481 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3482 lib/silccore/silcpacket.h. This packet is used t send list of
3483 Set Mode payloads inside one packet. Server uses this to set
3484 the modes for the channels and clients on those channels, that it
3485 announced to the router when it connected to it. The protocol
3486 specification has been updated accordingly.
3488 * The silc_server_new_channel did not handle the packet coming
3489 from normal server as it normally does not send that. However,
3490 when it announces its channels it does send it. Implemented
3491 the support for that.
3493 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3494 into the file lib/silccore/id.h.
3496 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Fixed memory leaks in the functions silc_idlist_del_client,
3499 silc_idlist_del_channel and silc_idlist_del_server in the file
3500 silcd/idlist.c. All of those leaked like a sieve.
3502 * Fixed some small memory leaks in the client's function
3503 silc_client_notify_by_server.
3505 * Added functions into silcd/server.c: silc_server_announce_clients,
3506 silc_server_announce_channels and silc_server_announce_server.
3507 These functions are used by normal and router server to announce
3508 to its primary router about clients, channels and servers (when
3509 router) that we own. This is done after we've connected to the
3512 These functions effectively implements the following packet types:
3513 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3514 and SILC_PACKET_NEW_ID_LIST.
3516 * Added new functions into the silcd/packet_receive.[ch]:
3517 silc_server_new_id_list, silc_server_new_channel_list and
3518 silc_server_new_channel_user_list to handle the incoming
3519 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3521 * Added support of changing Channel ID in the function
3522 silc_server_replace_id. If the server that announces a channel
3523 to the router already exists in the router (with same name but
3524 with different Channel ID), router is responsible to send
3525 Replace ID packet to the server and force the server to change
3526 the Channel ID to the one router has.
3528 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3529 client that the Channel ID has been changed by the router. The
3530 normal server sends this to the client. Client must start using
3531 the new Channel ID as the channel's ID.
3533 Implemented handling of this new type into lib/silcclient/client.c
3534 into the function silc_client_notify_by_server.
3536 * Added new function silc_idlist_replace_channel_id into the files
3537 silcd/idlist.[ch] to replace the Channel ID.
3539 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Call silc_server_command_identify_check always when processing
3542 the IDENTIFY command in silcd/command.c
3544 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3547 send keepalive packets. The packet can be sent by clients,
3548 servers and routers.
3550 Added function silc_socket_set_heartbeat into the file
3551 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3552 If not set, the heartbeat is not performed. The actual
3553 heartbeat is implemented in the low level socket connection
3554 library. However, application is responsible of actually
3557 Added silc_server_send_heartbeat to send the actual heartbeat
3558 packet into silcd/packet_send.[ch]. Server now performs
3559 keepalive with all connections.
3561 * Added silc_task_get_first function into lib/silcutil/silctask.c
3562 to return the timeout task with shortest timeout. There was a bug
3563 in task unregistration that caused problems. TODO has been
3564 updated to include that task system must be rewritten.
3566 * The client library will now resolve the client information when
3567 receiving JOIN notify from server for client that we know but
3568 have incomplete information.
3570 * Rewrote parts of silc_server_remove_from_channels and
3571 silc_server_remove_from_one_channel as they did not remove the
3572 channel in some circumstances even though they should've.
3574 * Encryption problem encountered in server:
3576 The LEAVE command used to send the Channel Key packet to the
3577 router immediately after generating it. However, the code
3578 had earlier sent Remove Channel user packet but not immediately,
3579 ie. it was put to queue. The order of packets in the router
3580 was that Channel Key packet was first and Remove Channel User
3581 packet was second, even though they were encrypted in the
3582 reverse order. For this reason, MAC check failed. Now, this
3583 is fixed by not sending the Channel Key packet immediately but
3584 putting it to queue. However, this is more fundamental problem:
3585 packets that are in queue should actually not be encrypted
3586 because packets that are sent immediately gets encrypted
3587 actually with wrong IV (and thus MAC check fails). So, packets
3588 that are in queue should be encrypted when they are sent to
3589 the wire and not when they put to the queue.
3591 However, the problem is that the current system has not been
3592 designed to work that way. Instead, the packet is encrypted
3593 as soon as possible and left to the queue. The queue is then
3594 just purged into wire. There won't be any fixes for this
3595 any time soon. So, the current semantic for packet sending
3598 o If you send packet to remote host and do not force the send
3599 (the packet will be in queue) then all subsequent packets to the
3600 same remote host must also be put to the queue. Only after the
3601 queue has been purged is it safe again to force the packet
3604 o If you send all packets immediately then it safe to send
3605 any of subsequent packets through the queue, however, after
3606 the first packet is put to queue then any subsequent packets
3607 must also be put to the queue.
3609 Follow these rules and everything works fine.
3611 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Added new function silc_server_remove_clients_by_server to
3614 remove all client entries from ID list when the server connection
3615 is lost. In this case it is also important to invalidate all
3616 client entires as they hold the invalid server entry. This
3617 fixes fatal bug when server has lost connection and will reconnect
3620 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Made some sanity checks to silc_server_daemonise like to check
3623 whether the requested user and group actually exists.
3625 * Added sanity check to SKE's silc_ske_responder_finish to check
3626 that the public and private key actually is valid.
3628 * Invalidate the client's nickname when receiving Replace ID
3629 packet and the Client ID is being replaced. This means that the
3630 server will query the nickname if someone needs it (client)
3633 * Sort the ID Cache in client library when the ID Cache data
3634 has changed (needs sorting).
3636 * Do not allow for SILC client to create several connections to
3637 several servers. The client does not support windows right now
3638 and generating multiple connections causes weird behaviour.
3640 Irssi-silc client does support windows and can handle several
3641 connections without problems, see: www.irssi.org and SILC plugin.
3643 * Fixed some places where client was added to the IDList. The
3644 rule of thumb is following (in order to get everything right):
3645 If the client is directly connected local client then the
3646 `connection' argument must be set and `router' argument must be
3647 NULL to silc_idlist_add_client function. If the client is not
3648 directly connected client then the `router' argument must
3649 bet set and the `connection' argument must be NULL to the
3650 silc_idlist_add_client function.
3652 * The funtion silc_server_packet_send_local_channel actually did
3653 not check whether the client was locally connected or not. It
3654 does that now. Fixed a bug related to LEAVE command.
3656 * Fixed Remove Channel User payload parsing bug in server's
3657 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3659 * The server's silc_server_save_channel_key now checks also the
3660 global ID list for the channel as it might not be in the local
3661 list. Fixed a bug related to LEAVE command.
3663 * Is this the end of the [<unknown>] buglet that has been lurking
3664 around for a long time? A little for loop fix in server's
3665 silc_server_command_whois_parse that is used by both IDENTIFY
3666 and WHOIS command. At least, this was a clear bug and a cause
3667 of one type of [<unknown>] buglet.
3669 * WHOIS and IDENTIFY commands call the function
3670 silc_server_command_[whois/identify]_check function even if
3671 we are not router server.
3673 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Added --with-gmp configuration option. If set the GMP
3676 is always compiled in the SILC source tree. If not set then
3677 it is checked whether the system has the GMP3 installed. If
3678 it has then the GMP won't be compiled (the system's headers
3679 and library is used), if it doesn't have it then the GMP is
3680 compiled in the SILC source tree.
3682 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Changed RSA private exponent generation to what PKCS #1
3685 suggests. We try to find the smallest possible d by doing
3686 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3687 not security fix but optimization.
3689 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Added new config entry [Identity] to fork the server and run
3692 it as specific user and group. A patch from Bostik.
3694 * Imported Dotconf configuration library into lib/dotconf.
3695 This will be used to create the SILC configuration files later.
3696 It will appear in the distsribution after this commit.
3698 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * A big code auditing weekend happening. Auditing code for
3701 obvious mistakes, bugs and errors. Also, removing any code
3704 Removed files for being obsolete:
3706 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3707 inline in the file lib/silcutil/silcbuffer.h)
3709 o lib/silcutil/silcbufutil.c (the header has inline versions)
3711 Changed code to fix possible error conditions:
3713 o The buffer formatting routines now check that the destination
3714 buffer really has enough space to add the data. This applies for
3715 both buffer formatting and unformatting
3716 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3717 unformatting was changed to accomodate following rules:
3718 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3719 sent to the function while XXX_*STRING will not allocate or copy
3720 the data into the buffer. Instead it sets the pointer from the
3721 buffer into the pointer sent as argument (XXX_*STRING used to
3722 require that the pointer must be allocated already). This change
3723 makes this whole thing a bit more consistent and more optimized
3724 (note that the data returned in the unformatting with XXX_*STRING
3725 must not be freed now). The routines return now -1 on error.
3727 o Tried to find all code that use buffer_format and buffer_unformat
3728 and added return value checking to prevent formatting and
3729 especially unformatting errors and possible subsequent fatal
3732 o Changed ske->x and ske->KEY to mallocated pointers in
3733 lib/silcske/silcske.h. Fixed possible data and memory leak.
3735 o Added return value checking to all *_parse* functions. Fixed
3736 many memory leaks as well.
3738 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3739 so that buffer overflows would not happen. All code now also
3740 checks the return value as it can fail.
3742 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Added reconnection support to server if the normal server looses
3745 its connection to the router (for example if router is rebooted).
3746 The server performs normal reconnection strategy implemented
3747 to the server. Affected file silcd/server.c.
3749 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Added new packet type SILC_PACKET_SET_MODE that is used to
3752 distribute the information about changed modes (for clients,
3753 channels and clients channel modes) to all routers in the
3754 network. Updated the protocol specification accordingly.
3756 Added functions into silcd/packet_send.c and
3757 silcd/packet_receive.c: silc_server_send_set_mode,
3758 silc_server_set_mode.
3760 Added new files silcmode.[ch] into lib/silccore that implements
3761 the encoding and decoding of Set Mode Payload. Added new type
3762 SilcSetModePayload. Moved the definitions of different modes
3763 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3765 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Oops, a little mistake in server's connection authentication
3768 protocol. The protocol is not ended with FAILURE but with
3769 SUCCESS if the authentication is Ok. :) Affected file is
3772 * Implemented NICK_CHANGE notify handling in server in the file
3773 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3774 the local clients on the channel. After the changing nickname
3775 in router environment snhould work and the [<unknown>] nickname
3776 should appear no more.
3778 The silc_server_replace_id function that receives the Replace ID
3779 payload now sends the NICK_CHANGE notify type also in the file
3780 silcd/packet_receive.c
3782 * Changed WHOIS and IDENTIFY command to support the maximum amount
3783 of arguments defined in protocol specs (3328 arguments). This
3784 fixed a bug that caused problems when there were more than three
3787 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added extra parameter, command identifier, to the
3790 silc_client_send_command so that explicit command identifier
3793 Changed that ID list routines uses specific command identifier
3794 when sending WHOIS/IDENTIFY requests to the server so that they
3795 can be identified when the reply comes back.
3797 Affected files lib/silcclient/command.[ch],
3798 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3800 * Added `sender' argument to silc_server_packet_send_to_channel
3801 to indicaet the sender who originally sent the packet to us
3802 that we are now re-sending. Ignored if NULL. Affected file
3803 silcd/packet_send.[ch].
3805 * Added some server statistics support in silcd/server_internal.h
3806 SilcServerStatistics structure and around the server code. Also
3807 send some nice statistics information when client is connecting
3810 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Fixed channel ID decoding in server's JOIN command reply in
3813 silcd/command_reply.c
3815 * Fixed braodcasting of replace ID payload to not to send it if
3816 we are standalone server in silcd/packet_receive.c.
3818 * Fixed all channel message sending routines to not to send
3819 packets to clients that has router set, since they are routed
3820 separately in the same function earlier. Affects file
3821 silcd/packet_send.c and all channel packet sending functions.
3823 * In USERS reply, res_argv[i] are not allocated, the table
3824 is allocated. Thus changed that free the table, not its
3827 * In server's whois_check and identify_check if the client is
3828 locally connected do not send any WHOIS commands - they are not
3831 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Fixed some minor bugs in client when sending WHOIS command. The
3834 arguments was in wrong order.
3836 * Removed statis function add_to_channel from server in
3837 silcd/command.c that was previously used with the joining but
3840 * Tested USERS command in router environment successfully with two
3841 routers, two servers and two clients.
3843 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Reorganized the USERS command and command reply in client library
3846 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3847 When the command is given by user we register a pending command
3848 callback that will reprocess the command after the reply has been
3849 received from the server. When reprocessing the packet we then
3850 display the information. Thus, the USERS information is displayed
3851 now in the command callback instead of in the command reply
3852 callback. The processing of the command is same as previously
3853 when server has sent the command reply in the JOINing process.
3855 * Added to USERS command in silcd/command_reply.c to join the client,
3856 we didn't use to know about, to the channel after we've created
3857 a client entry for it. Also, for clienet we did know already still
3858 check whether it is on the channel or not and add it if not.
3860 * Removed silc_server_command_join_notify as the function and its
3863 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * Changed the client's pending command handling to the same as the
3866 server's pending command handling. It is also now possible to
3867 execute command reply functions from other command reply
3868 function as the function callbacks for commands and command
3869 replies are one and same. The pending commands are not static
3870 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3871 in client connection context. Thus, pending commands are server
3872 connection specific as it is convenient.
3874 Changed the function silc_client_command_pending and
3875 silc_client_command_pending_del and added new function
3876 silc_client_command_pending_check. Removed the
3877 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3880 * Added cmd_ident, current command identifier, to the client
3881 connection context in lib/silcclient/client.h to keep track on
3882 command identifiers used in command sending. Client's command reply
3883 function handling now supports the mandatory command identifiers.
3885 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3886 funtions in client to fully support pending command callbacks.
3888 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3889 as one of the arguments to the application in the command reply
3892 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3893 before first releasing SILC but came back. Now it is removed again
3894 and should come back nomore. The FORWARDED flag was used only
3895 by the JOINing procedure by forwarding the command packet to router.
3896 Now, the JOINing procedure has been changed to more generic (due
3897 to various router environment issues) and FORWARDED is not needed
3898 anymore for anything. The protocol specification is yet to be
3901 Now, removed silc_server_packet_forward from server and the flag
3902 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3904 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Renamed NAMES command to USERS command. The NAMES was named that
3907 due to historical reasons. Now it is renamed. Also, rewrote
3908 parts of the USERS command. The nickname list is not sent anymore
3909 by the server. Only Client ID and mode lists are sent in the USERS
3910 command. Changed this also to the protocol specification.
3912 The client now resolves the names and stuff after it receives
3913 the USERS list from the server when joining to the channel.
3915 * WHOIS and IDENTIFY commands has been changed to support multiple
3916 Client ID's per command. One can now search for multiple users
3917 in the network by sending only one WHOIS or IDENTIFY command.
3918 Changed the code and the protocol specifications.
3920 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3921 uses silc_server_command_whois_parse to parse the request. */
3923 * If normal server, do not parse the WHOIS and IDENTIFY requests
3924 before sending it to the router. Saves some time.
3926 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Fixed JOIN command on client library. Wrong number of arguments
3929 used to crash the client.
3931 * Added silc_server_channel_has_global function to check whether
3932 channel has global users or not.
3934 * Added silc_server_channel_has_local function to check whether channel
3935 has locally connected clients on the channel.
3937 * The silc_server_remove_from_one_channel now checks whether the
3938 channel has global users or not after given client was removed from
3939 the channel. It also checks whether the channel has local clients
3940 on the channel anymore. If it does not have then the channel entry
3941 is removed as it is not needed anymore.
3943 * The silc_server_notify now checks on JOIN notify whether the joining
3944 client is one of locally connected or global. If it is global then
3945 the channel has now global users on the channel and that is marked
3946 to the channel entry. Also, it now saves the global client to
3947 global list who is joining and JOINs it to the channel. This is
3948 for normal server, that is.
3950 Changed silc_server_send_notify_on_channel,
3951 silc_server_packet_relay_to_channel and
3952 silc_server_packet_send_to_channel check if we are normal server
3953 and client has router set (ie. global client) do not send the
3954 message to that client, as it is already routed to our router.
3956 * Implemented LEAVE notify type handling in silc_server_notify
3959 * Tested LEAVE command in router environment successfully. Tested
3960 with two routers, two servers and two clients.
3964 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3966 * Implemented SIGNOFF notify type handling in silc_server_notify
3969 * silc_server_remove_id now removes the client entry from all channels
3970 it has joined and thusly sends SIGNOFF notify type.
3972 * Rewrote the NAMES list generation in server by removing two excess
3973 loops. The lists are created now inside one loop.
3975 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * silc_server_remove_channel_user checks now also global list
3978 for channel and client.
3980 * silc_server_new_channel_user checks now both local and global
3981 list for channel and client. Fixed a bug in client id decoding.
3982 Used to decode wrong buffer.
3984 * silc_server_channel_message checks now both local and global
3985 list for channel entry.
3987 * Tested channel joining (hence JOIN) in router environment
3988 successfully. Tested with two routers, two servers and two
3991 * Tested channel message sending in router environment successfully.
3993 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Added silc_server_save_channel_key into server.[ch] to save the
3996 received channel key in Channel Key payload processing. It is
3997 also used in JOIN command reply handling.
3999 Equivalent function silc_client_save_channel_key added into
4000 client.[ch] into client library.
4002 * Changed JOIN command reply to send information whether the channel
4003 was created or not (is existing already) and the channel key
4004 payload. Changed protocol specs accordingly.
4006 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4007 the request was sent by ID and not by nickname. Crashed on
4010 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4013 now correctly save the received data.
4015 * silc_server_free_sock_user_data now notifies routers in the
4016 network about entities leaving the network.
4018 At the same time implemented functions silc_server_remove_id
4019 and silc_server_send_remove_id to receive and send REMOVE_ID
4020 packets. The packet is used to notify routers in the network
4021 about leaving entities. The ID removed will become invalid in
4024 * Added function silc_idlist_del_server into server. Removes and
4025 free's server entry from ID list.
4027 * silc_server_private_message function now checks, if we are router,
4028 that the destination ID really is valid ID, naturally.
4030 * In router when NEW_ID packet is received (for new client) the
4031 hash of the Client ID is saved in the ID Cache but the
4032 client->nickname is set to NULL, instead of putting the hash
4035 IDENTIFY command now also checks that client->nickname must be
4036 valid. If it is not if will request the data from the server who
4037 owns the client. Added new function
4038 silc_server_command_identify_check.
4040 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4041 to set the command to already allocated Command Payload.
4043 * Tested private message sending in router environment with two
4044 routers, two servers and two clients. Fixed minor bugs and now
4047 * Fixed segfault from client's NAMES command. Used to crash if
4050 * Forwarded packets must not be routed even if it is not destined
4051 to the receiver. Changed server code comply with this.
4053 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Added `require_reverse_mapping' boolean value to ServerParams
4056 structure. If TRUE (not default) the server will require that
4057 the connecting host has fully qualified domain name.
4059 If the reverse mapping is not required and hostname could not be
4060 found the IP address is used as hostname.
4062 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Implemented version string checking to both client and server.
4065 The check is incomplete currently due to the abnormal version
4066 strings used in development version of SILC.
4068 * Changed all command functions in server to use the new
4071 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Changed char *data to unsigned char *data in ID Cache system to
4074 support binary data as ID Cache data. Changed code to support
4075 binary data in lib/silccore/idcache.c.
4077 * Renamed silc_server_packet_relay_command_reply to
4078 silc_server_command_reply as it is normal packet receiving
4079 function. Rewrote the function to accept command replys for
4080 servers and not only for clients.
4082 * Mark remote router always as registered server if we are connecting
4083 to it. Otherwise, commands sent by the router to us are ignored.
4085 * All ID List find routines now returns the ID Cache Entry pointer
4086 as well if requested.
4088 * WHOIS command works now in router environment, tested with two
4089 routers, two servers and two clients.
4091 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4092 in router environment (as it is almost equivalent to WHOIS) but
4093 hasn't been tested thoroughly. Added new functions:
4095 silc_server_command_identify_parse
4096 silc_server_command_identify_send_reply
4097 silc_server_command_identify_from_client
4098 silc_server_command_identify_from_server
4100 * Disabled route cache adding because adding two different ID's with
4101 same IP replaces the old cache entry thus giving wrong route.
4102 The entry->router->connection is always the fastest route anyway
4103 so route cache may not be needed. Of course, new routes maybe
4104 established after receiving the ID when the entry->router->connection
4105 might not be anymore the most optimal.
4107 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Add route cache for received ID for fast routing.
4111 * Added silc_server_packet_route to route received packet on router
4112 that is not destined to us.
4114 * Renamed silc_server_get_route to silc_server_route_get.
4116 * Added id_string and id_string_len fields into SilcServer to
4117 include encoded ServerID for fast comparing without excess
4118 encoding of the ID's.
4120 * Cleaned up WHOIS command on server side. Added following static
4123 silc_server_command_whois_parse
4124 silc_server_command_whois_check
4125 silc_server_command_whois_send_reply
4126 silc_server_command_whois_from_client
4127 silc_server_command_whois_from_server
4129 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4130 arguments in command replies. All command functions should be
4131 updated to use this macro.
4133 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Minor typo fixes on command reply handling on server.
4137 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Added silc_server_command_add_to_channel internal routine to add
4140 the client to the channel after router has created the channel and
4141 sent command reply to the server.
4143 * Added generic silc_server_send_command to send any command from
4146 * Use static buffer with ID rendering instead of duplicating data.
4148 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Fixed a channel user mode bug when joining to a channel server gave
4151 everybody channel founder rights, oops.
4153 * We mark ourselves as the router of the incoming server connection
4154 if we are router ourselves. This way we can check in some packet
4155 sending functions whether it is locally connected server. For
4156 incoming router connections we put NULL.
4158 * For router sending packets locally means now always sending the
4159 packet cell wide; to local clients and local servers. For normal
4160 server sending packet locally means sending it to only local
4163 * Fixed the JOIN command to really work in router environment. If the
4164 channel is created it is always created by the router. Router is
4165 also responsible of making the initial joining to the channel,
4166 sending JOIN notify to the sending server and distributing
4167 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4168 does not exist server doesn't do anything else but forward the
4169 command to the router which performs everything.
4171 * Added silc_server_send_channel_key function to send the Channel Key
4174 * Added silc_server_create_channel_key to create new channel key. The
4175 channel key is now re-generated everytime someone joins or leaves
4176 a channel, as protocol dictates. Note: channel->key_len is the
4179 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4182 packet_receive.[ch] to separate packet sending and receiving
4183 routines. The server.[ch] now includes everything else including
4184 actual packet processing (writing and reading data) and other
4187 Renamed silc_server_private_message_send_internal to
4188 silc_server_send_private_message. The routine is still though
4189 used only to relay private messages as server does not send
4190 private messages itself.
4192 Renamed silc_server_new_channel to silc_server_create_new_channel
4193 and added new function sicl_server_new_channel that handles the
4194 incoming New Channel packet. Added also new sending function
4195 silc_server_send_new_channel to send New Channel Payload.
4197 * Added new function silc_server_notify to process incoming notify
4198 packet to the server/router. Server may then relay the notify
4199 to clients if needed.
4201 * Added new function silc_server_new_channel_user to process incoming
4202 New Channel User packet. Router will redistribute the packet and
4203 send JOIN notify to its local clients and locally connected servers
4204 if needed. Normal server will send JOIN notify to its local client
4205 on same channel when received this packet. Added also corresponding
4206 sending function silc_server_send_new_channel_user to sent the
4209 * Added boolean route argument to send_notif_to_channel and
4210 packet_send_to_channel functions to attempt to route the packet
4211 if it is TRUE and send only locally if it is FALSE.
4213 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * silc_server_replace_id now broadcasts the received replace ID
4216 packet if it is not broadcast packet already. The router must
4217 broadcast to inform other routers about changed ID.
4219 * Added backpointer to server's router into SilcServer context in
4220 silcd/server_internal.h.
4222 * Fixed silc_server_packet_broadcast to send correct broadcast
4225 * The channel key is now distributed to the local client as soon
4226 as it is received from the router (in router environment) so that
4227 no other packet may be sent for the channel until client has
4230 * silc_server_remove_channel_user now broadcasts the received
4231 Remove Channel User packet if it is not broadcast packet already.
4232 The router must broadcast to inform other routers about removed
4235 * Added users field into SilcPacketContext that is a reference count
4236 of the context. One can increase the reference count by calling
4237 silc_packet_context_dup which is now changed to just increase the
4238 reference count instead of duplicating the data. The reference
4239 count is decresed by calling silc_packet_context_free that will
4240 free the data after the reference count hits zero.
4242 For now on the packet context and everything allocated into it
4243 (including the raw packet from network) must be freed by calling
4244 the new silc_packet_context_free function. Added also new function
4245 silc_packet_context_alloc that must be used now to allocate the
4246 context. This also means that if a routine is asynchronous from
4247 silc_[client/server]_packet_parse_type the packet context must
4248 be duplicated by calling silc_packet_context_dup. Otherwise it
4249 gets free'd after silc_[client/server]_packet_parse_type returns.
4250 Also, one must remember that if packet is duplicated then its
4251 reference count must be decresed by calling the free function as
4252 many times as it was duplicated.
4254 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4255 from both client and server.
4257 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Made joining to a channel working in router environment.
4261 * Cleaned up JOIN command on server side and create function
4262 silc_server_command_join_channel internal routine to make the
4265 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Changed silc_command_pending list to SilcDList. Also, added
4268 `ident' field to SilcServerCommandPending structure to identify
4269 the reply and to call correct callback.
4271 Added silc_server_command_pending_check function to replace the
4272 corresnponding macro. The silc_command_pending list is not
4275 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4276 to set identifier to previously allocated Command Payload. It
4277 is used to set identifier for command when resending Command
4280 * Added silc_command_payload_encode_payload to encode Command
4281 Payload buffer from SilcCommandPayload structure.
4283 * Added silc_argument_payload_encode_payload to encode Argument
4284 payload buffer from SilcArgumentPayload structure.
4286 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Changed WHOIS command to support router connection on server side.
4289 The whois request is always sent to router unless the server is
4290 standalone server. After server has received the reply from the
4291 router will it send the reply to the client.
4293 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4294 broadcast received broadcast packet. The function is used only
4295 by router. The broadcast packet is always sent to the router's
4298 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4299 render given ID to printable string, for log files for example.
4301 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Made basic router to router connections working. At least they
4304 can now connect to each other but nothing really works the way
4305 they are supposed - yet.
4307 * Added new initiator token to RouterConnection configuration
4308 file in silcd/serverconfig.[ch]. It is used to tell whether we
4309 are the initiator to the remote router or whether we'll expect
4310 the other end to connect.
4312 * Moved registering of listener task to silc_server_init, hence
4313 the server starts listenning as soon as it is run, even if it
4314 does not have connections to other routers. Let's see how well
4317 * Changed default connection retry timeouts for more suitable in
4320 * Removed cipher and such arguments from silc_idlist_add_client
4321 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4322 Added new function silc_idlist_add_data to add the keys and stuff
4325 * Added SilcIDListData structure and added it to SilcClientEntry
4326 and SilcServerEntry as their first field in the structure. This
4327 way we can explicitly cast the ID entries to the SilcIDListData
4328 structure and get common data for the entries. In past, we had
4329 to first check what type of connection it is and then cast it to
4330 correct ID entry type. Now, we can directly cast the opaque
4331 pointer to the SilcIDListData (no matter what ID entry it actually
4332 is) and get the data needed.
4334 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4337 in some circumstances even if threre were timeout tasks, though not
4338 IO tasks, but tasks anyway. Now fixed.
4340 * Defined SilcServerConnection structure to hold connection specific
4341 stuff about directly connected servers and routers. The definition
4342 is currently in silcd/server_internal.h. I thought about having
4343 a bit more important role fro this struct but for now it is used
4344 only when connecting to other server (or router actually).
4346 * Added connecting retry support in server when connecting to
4347 router(s). The retry feature implement exponential backoff
4348 algorithm. Also, added SilcServerParams structure to hold default
4349 parameters for server. For now, it include these retry settings
4350 and are hard coded. After server is moded to be as Silc Server
4351 Library this structure will be more important.
4353 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Changed client librarys channel->clients table to SilcList and
4356 changed code accordingly.
4358 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Changed client's channel table to SilcList and changed code
4361 accordingly. Also changed SilcChannelClientEntry to include back-
4362 pointer to the channel so that client entry can use that structure
4363 as list as well and we have fast cross-reference to the channel.
4364 This change dramatically decreased the complexity of channel
4365 handling with client entry and vice versa (removed one extra
4366 loop when searching for channel entry from many functions).
4368 * Changed server->sim from table to SilcDList and changed code
4371 * NAMES command can now be used from user interface. It will show
4372 the user list on the channel, neatly.
4374 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4375 Code now saves realname of the user if it becomes available.
4377 * Renamed configure.in to configure.in.pre and made ./prepare
4378 script to automatically add correct version string to
4379 configure.in which it creates from configure.in.pre.
4381 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * NAMES command reply now shows users mode with the nickname when
4386 * Moved silc_client_ch[u]mode[_char] functions from
4387 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4388 place sucks, they are utility functions and should be in some
4391 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4393 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4396 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Added TRQ (efficient deque and list library) into lib/trq. This is
4401 a very good list library that is currently used in the SILC. Defined
4402 SilcList API over the library because I didn't like the API very
4403 much. See lib/trq/silclist.h for the API and examples of how to
4404 use the API. Fixed various places in the code to use the new
4405 SilcList API. The SilcList is meant for lists that has a structure
4406 already defined as a list. It is not suitable to add just some
4407 context to the list (in TRQ, the context is the list actually).
4409 So, I defined SilcDList that can be used for the purpose where
4410 predefined list structure does not exit. This can be used as
4411 such list. Now some context just can be added to the SilcDList.
4412 Currently this list is not used in the SILC just yet, though there
4413 are a lot places where this can replace dynamically allocated
4414 tables and I will fix these places, later, to use SilcDList.
4415 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4416 and use TRQ internally).
4418 Also fixed some annoying warning messages that the original TRQ
4419 code generated. Also minor changes to TRQ's Makefile.in.
4421 * Added support for querying by Client ID to both WHOIS and
4422 IDENTIFY commands into server, as required by the protocol.
4424 * Removed method function pointers from SilcBuffer structure. They
4425 weren't used to anything and just increased the context size for
4426 no good reason. This change also made silc_buffer_alloc and
4427 silc_buffer_free functions inline functions.
4429 * Disabled command flooding detection support until it's fixed so
4430 that it accepts commands in but does not execute them more than once
4433 * Added silc_net_localhost(), to return local hostname, into
4434 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4435 that must be initialized before calling silc_client_init.
4437 * Added new function: silc_server_send_notify_on_channels to send
4438 notify messages to all channels client has joined. It is assured
4439 that the message is sent only once per client.
4441 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4442 lib/silcutil/silcutil.[ch] as silc_format function. The new
4443 function is generic and is used by server as well, not only by
4444 the logging routines.
4446 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4447 the provided version string was not acceptable. Added new function:
4448 silc_ske_check_version into lib/silcske/silcske.h. The function
4449 must be implemented by the application (client or server) and it
4450 does not reside in the SKE library. The function checks the version
4451 string remote end sent.
4453 * Added back pointers (to opaque context and to SilcSocketConnection)
4454 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4456 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4457 duplicate packet context structure.
4459 * Changed `notify' client operation to send same arguments as client
4460 receives from server except for ID's. ID's are mapped to correct
4461 ID entry and that is returned. Also, if channel entry is not sent
4462 by server but the notify is for channel the channel entry is sent
4463 to application (otherwise application doesn't know that it is for
4464 channel (library gets it from packet's Destination ID)).
4466 * Added silc_client_remove_from_channels into client library to
4467 remove a client from all channels it has joined to. Used when
4468 received SIGNOFF notify from server. Added also new function
4469 silc_client_replace_from_channels to replace old ID entry with
4470 new ID entry on all channels. Used when received NICK_CHANGE
4473 * Fixed ID Cache list handling in silc_idlist_get_client in
4474 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4475 to get (or query) client by ID.
4477 * Updated TODO list.
4479 * Added connection authentication status message defined by the
4480 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4481 support for these into the code in client and server side.
4483 * Added generic function silc_client_send_command to send any command
4484 with variable argument list. Application should use this function
4485 to send commands if the command functions provided by the library
4486 does not suite for the application's user interface needs.
4488 * Added new `failure' client operation. Application is notified about
4489 received failure packet if client is executing a protocol. In this
4490 case the protocol's execution has failed.
4492 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4493 is required by the protocol.
4495 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4496 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4499 * Added status flag to SilcSKE object to indicate realtime status
4500 of the SKE protocol.
4502 * Application receives now exactly same command reply arguments as
4503 the library receives from server. However, if ID is received the
4504 corresponding ID entry is returned to the application (eg. Client
4505 ID is mapped to correct SilcClientEntry entry and that is returned).
4506 Changed command_reply client operation due to this change.
4508 * Changed all ID's in commands and in command replys as ID Payloads.
4509 Change affected both client and server side codes.
4511 All ID's sent in SILC network (with execption of ID's in SILC
4512 Packet header) are sent in ID Payload to support variable length
4515 * Server now notifies nick changes and notifies all clients on
4516 the channels about the new nickname (about the new Client ID,
4519 * Implemented CMODE command to change channel modes. Supports all
4520 channel modes defined by the protocol specs except ban and invite
4521 lists. (Also, private channel key mode is supported but support for
4522 setting private channel key in client is missing, thus, this mode
4523 has no effect on client side (except that server requires that the
4524 client uses private channel key and normal channel traffic does not
4527 Also, invite mode works per se, but INVITE command does not work
4528 yet correctly, so you can set channel as invite only channel but
4529 inviting clients to the channel does not work (it is yet to be
4530 thought what's the best way to do it).
4532 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4533 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4534 Implemented CUMODE command to change user's mode on the channel.
4535 Supports all modes defined by the protocol specs.
4537 * Added NAMES command reply to return users modes on the channel.
4539 * Removed unnecessary and slow ciphers from lib/silccrypt.
4541 * Set SO_KEEPALIVE option to connection sockets by default.
4543 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4545 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4546 redefined the Notify Payload into protocol specs.
4548 * Added silc_id_payload_parse_id to get ID directly from raw
4551 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4554 accept searching by Client ID as well.
4556 * Added support for LEAVE and SIGNOFF notify types in client library.
4558 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4559 to parse ID Payload from raw data.
4561 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added flags parameter into silc_ske_assemble_security_properties
4564 function in lib/silcske/silcske.[ch].
4566 * Changed notify client operation to fit better for notify messages
4567 sent by server. The notify payload received from server is now
4568 passed to the application (after parsing it to SilcNotifyPayload).
4569 It is application's responsibility to retrieve the arguments
4570 from the payload and show the message the way it wants. The message
4571 sent by server is implementation specific.
4573 * Changed public keys to comply with the protocol specification.
4574 Old public keys are not supported anymore and are not compatible.
4576 * Removed nickname from Channel Payload as the latest draft removed
4577 it. The client must resolve the nickname from the NAMES command
4578 reply received when it joined the channel.
4580 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4582 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Fixed some errors in protocol specification drafts.
4586 * Created lib/silccore/silcnotify.c to implement Notify Payload
4587 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4588 generic payloads described by protocol specifications. The file
4589 includes implementations for ID Payload and Argument Payload.
4591 * Changed Command Payload implementation to use the new Argument
4592 Payload. Changed command_xxxx_payload to command_payload_xxxx
4593 to comply with SILC coding conventions.
4595 * Added suppport for Argument Payload handling in Notify Payload
4596 implementation as protocol requires it. Added the new support
4597 into server and client lib as well.
4599 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Added support for multiple nicknames on same channel. [n] is
4602 added locally to the nickname if there are more than one same
4603 nicknames on the channel.
4605 * Server now sends all nicknames that matched WHOIS request.
4606 Client also shows the list received from server.
4608 * Added TOPIC command to client side. User can now set and show
4609 current topic on channel.
4611 * Added MOTD command to client and server. Also, server sends the
4612 motd when client connects to the server.
4614 * Changed version strings to comply ISO 8601.
4616 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Fixed protocol error handling in client library. It should now
4619 cope even if the SKE fails for some reason.
4621 * Made new protocol specification drafts for submitting to IETF.
4623 * Implemented TOPIC command to server in silcd/command.c.
4625 * Added two new notify types into lib/silccore/silcnotify.h:
4626 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4627 notify nickname change and topic setting/change on a channel.
4629 * API change of command_reply operation in client library. The
4630 application gets now the status type received from server as well.
4632 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4636 * Cras fixed and optimized the packet handling even further and
4637 it should work now. Minor change to the prototype of function
4638 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4640 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Added new function into lib/silcutil/silcschedule.[ch]:
4643 silc_schedule_with_fd to select() a specified fd. The function
4644 returns after timeout expires or data arrives or goes. The
4645 function is used by packet routines to wait that all data is
4646 received from network.
4648 * Fixed data reading from network in lib/silccore/silcpacket.c.
4649 The code now assures that all data is read from the fd and then
4650 continues packet processing. This was a bug fix since the code
4651 used to drop some data in some circumstances.
4653 * Added new function into lib/silcclient/client.[ch]:
4654 silc_client_start_key_exchange to start key exchange after
4655 connection has been established to server. The code internally
4656 now uses this funtion but its main purpose was to provide it
4657 for applications that perform their own connecting. After
4658 application has created a connection it merely calls this
4659 function to start the key exchange between client and server.
4660 The library takes care of everything else after that.
4662 Updated also lib/silcclient/README to explain the usage of
4665 * Do not send to application information that connection has
4666 been established. Application gets notified it by connect
4669 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Applied cras's patch to add silc_schedule_one function. The
4672 function runs scheduler once and returns.
4674 * Fixed the scheduler after cras messed it up. The timeout
4675 handling works now as it's supposed to work.
4677 * Added into lib/silccore/ silcnotify.h to include notify
4678 message types support. Changed silc_server_send_notify*
4679 functions, in server.[ch], to support those new notify types.
4680 Added the support for the notify types into client library,
4681 as well. Added new notify client operation into ops.h in
4684 * Changed silc_server_packet_send_to_channel to send normal
4685 packets instead of just channel message packets. The function
4686 is now used to send the notify packets to channels. It is not
4687 used to send channel message packets anymore, as server never
4690 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4691 va_arg()s as it seems to require it nowadays. I guess, if SILC
4692 is compiled with older va_arg() the new code should work anyway.
4694 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Splitted core library. Core library (lib/silccore) includes
4697 now only SILC protocol specific core (and common) components.
4698 Created new utility library (lib/silcutil) that includes more
4699 generic purpose stuff. The stuff for util library was taken
4700 from the old core library. This was minor and easy split.
4702 * Created SILC Client Library (lib/silcclient) that includes
4703 implementation of the SILC client without user interface. This
4704 was major move from silc/ directory. The code has been changed
4705 so that it is transparent towards the user interface. The
4706 silc/ directory includes now the same user interface as before
4707 and it uses the new client library. Read lib/silcclient/README.
4708 Basicly, the client library performs everything else related
4709 to SILC except user interface handling. Also, configuration
4710 files are considered to be part of user interface and library
4711 does not handle them.
4713 This change also changed a lot of structures, function naming etc.
4714 Most important change was that SilcClientWindow object was
4715 renamed to SilcClientConnection in the client library. Created
4716 also new file lib/silcclient/ops.h. Also added new files
4717 silc/local_command.[ch] and silc/client_ops.[ch].
4719 All these changes were made to make it easier for user interface
4720 designers to create what ever user interface for the SILC client
4723 It is also expected that the server will be moved to lib
4724 directory as well and SILC Server Library will be created;
4725 sometimes in the future.
4727 * Removed Local commands from lib/silccore/silccommand.h as
4728 they are application specific and new client library does not
4729 handle any of those anymore.
4731 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4732 old client implementation in silc/.
4734 * Added support for callback functions in SILC_LOG_* macros.
4735 Application can now set its own callbacks that will be called
4736 instead of using the default functions that will always print
4737 the debug messages to stderr (or stdout). Also, debugging can
4738 now be disabled by setting silc_debug to FALSE and re-enabled by
4739 setting it to TRUE. Note, that logging will still work even
4740 if debugging is disabled.
4742 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4743 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4744 silc_log_reset_debug_callbacks.
4746 * To enable debugging in silc client one must give now -d
4747 option on command line.
4749 * Changed silc_schedule_init to automatically allocate task queues
4750 if they are not allocated before calling it.
4752 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Added GMP 3.1 into math library.
4756 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4759 a channel in SILC network. The packet is used by servers and
4760 routers to notify other routers that user has left a channel.
4761 This little feature was missing until now. Added the feature
4762 to protocol specification as well.
4764 Added functions: silc_server_send_remove_channel_user and
4765 silc_server_remove_channel_user into server.[ch].
4767 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4768 lib/silccore/silcpacket.h. However, they are not implemented
4771 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Fixed joining to a channel and sending channel messages
4774 between server and router. The channel message sending should
4775 now work inside a cell.
4777 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Fixed the private message sending between server and router.
4780 The private message sending should now work inside a cell.
4782 * Added silc_server_replace_id into server.[ch] to replace
4783 existing ID in the SILC network.
4785 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4786 and silc_idlist_replace_server_id into idlist.[ch] in server.
4788 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Fixed the server to server connections. Server can again now
4791 connect to router. Router to router connections probably does
4794 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Added dynamic protocol registering support. Now protocols can
4797 registered and unregistered on the fly. Patch by cras.
4799 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Added lib/contrib directory to hold routines that some platforms
4802 don't have but are needed by SILC.
4804 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4805 into lin/contrib to provide getopt() and getopt_long() for
4806 those who don't have it.
4808 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added AWAY command to client. When away message is set and
4811 client receives a private message packet the client automatically
4812 replies to the sender with the away message.
4814 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4815 bug seemed to be the cause of recent problems when compiling
4818 * Added version detection support to SKE protocol specification
4819 and added the new changes to the SKE implementation as well.
4820 There were other minor changes in the SKE protocol as well.
4822 Many changes in lib/silcske/silcske.[ch] and in
4823 lib/silcske/payload.[ch].
4825 * Added ^U functionality, clear input line. Patch from cras.
4827 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Mainly small bugfixes on core library. Fixed some debugging
4830 logging and buffer overflow in silclog.c.
4832 * Updated config.sub and config.guess on the distribution tree.
4834 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added command lagging support in server. Client may execute
4837 commands now only once in two seconds.
4839 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Optimized packet reception. MAC computation and checking is now
4842 also more optimized. A lot previously duplicated code is now
4843 used as generic by both client and server.
4845 * Fixed key pair generation in clientutil.c
4847 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Added into lib/silccore/silcbufutil.[ch] new function;
4850 silc_buffer_realloc.
4852 * Moved generic packet sending/encryption functions to
4853 lib/silccore/silcpacket.[ch] from client and server. Some
4854 rewriting of the functions.
4856 * Moved all generic packet reception/decryption functions to
4857 lib/silccore/silcpacket.[ch] from client and server. The
4858 packet processing is now much cleaner in both client and server.
4859 These were major changes in both client and server.
4861 * Created many common functions in server to do packet sending.
4862 Previously code were duplicated a lot, this has been removed
4865 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Rewrote major parts of the ID cache system. Don't know
4868 whether it is better now or not but at least the API is more
4871 * Major rewrite on ID cache stuff on client because of the ID
4872 cache API changes. Added idlist.c to client.
4874 * Also major rewrite on ID cache stuff on server as well.
4875 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4876 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4877 in hand, instead they are all put into the ID cache system now.
4878 All server_idlist_* routines uses ID cache now instead of
4879 traversing its own lists (those lists does not exist anymore).
4880 SilcIDList though still exists. Also, SilcXXXEntry's are
4883 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Finally made the SKE implementation compliant to the protocol
4886 specification. All mp integers are now binary encoded as
4887 opposed being HEX encoded.
4889 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4892 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4893 functions: silc_[encode/decode]_pem. Also added function
4894 silc_encode_pem_file to PEM encode with newlines ('\n') for
4897 * SILC public keys are now encoded either PEM or binary. Same
4898 option is for private keys as well. By default private keys
4899 are binary encoded and public keys PEM encoded. Silly HEX
4900 encoding were removed.
4902 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4903 function to create fingerprints.
4905 * Fixed a bug in SHA1; does not change the original data anymore.
4907 * Partly implemented INFO command on client and server side.
4908 Fixed CLEAR command. Changes to SERVER command; show current
4909 server(s) when giving command without arguments. Added
4910 VERSION command to client.
4912 * Added check to server that unregistered connections cannot
4913 execute commands (unless it is specificly allowed).

4917 * Fixed screen refresh.
4919 * Fixed channel joining bug from client. On some circumstances
4920 client tried to join to a channel it had already joined.
4922 * Added public key verification process into client's protocol.c.
4923 The client now verifies the public key from user and saves
4924 it into ~./silc/serverkeys/ directory.
4926 Added into: clientutil.[ch]: silc_client_verify_server_key.
4928 * Changed SKE protocol's silc_ske_initiator_finish function
4929 to accept callback function that verifies the received public
4930 key. Removed old silc_ske_verify_public_key function.
4932 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4935 silc_pkcs_private_key[_data]_set.
4937 * Made the password and public authentication more cleaner in
4938 server's protocol.c.
4940 * Removed historic and obsolete protocol `channel_auth' from
4941 both client and server.
4943 * Removed wrong way of sending command status messages from
4944 server to client in server's command.c. The old way violated
4945 protocol specification.
4947 Changes to silccore/silccommand.[ch]: removed
4948 silc_command_encode_status_payload -> not needed anymore,
4949 changed silc_command_encode_payload_va to accept extra
4950 argument on variable argument list. The argument type must
4951 now be provided to the function. Also, added new function:
4952 silc_command_encode_reply_payload_va which is same as
4953 normal command_encode_payload_va except command status type
4954 is provided as extra argument.
4956 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Added ~./silc directory handling. The directory includes the
4959 public and private keys for the client.
4961 Added silc_client_check_silc_dir, silc_client_create_identifier
4962 and silc_client_load_keys.
4964 * Implemented SILC protocol compliant public key. Added public
4965 and private key saving to and loading from files.
4967 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4968 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4969 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4970 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4971 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4973 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4974 silc_pkcs_load_[public/private]_key.
4976 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Added silc_server_get_route (route.[ch]) to get connection
4979 data for the fastest route for given ID.
4981 * Implemented INVITE command on client and server. The command
4982 were re-defined in the SILC Protocol Specification and the
4983 implementation now complies with the specification.
4985 * Implemented PING command on client and server.
4987 * Implemented NAMES command on client and server. The server side
4988 supports currently only normal server not router server yet.
4989 Some changes to NAMES definition in SILC protocol specification.
4991 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Implemented LEAVE command on client and server.
4995 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4996 again. This change was made to the protocol as well. Server
4997 should not violate the protocol specification anymore.
4999 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5002 was tested. SOCKS4 was not but should work anyway.
