1 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the configure.in.pre and the compilation and distribution
4 environment to support the new autoconf 2.52. That version is
5 now required to compile the CVS trunk.
7 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Renamed function silc_parse_nickname to silc_parse_userfqdn
10 to generally parse user@fqdn format strings. Affected file
11 lib/silcutil/silcutil.c.
13 * Added nickname_format and nickname_force_format fields to the
14 SilcClientParams structure. The first one defines the format
15 for the nicknames that the library will enforce if the receives
16 multiple same nicknames. The second one is boolean value and
17 can be used to force the library to always enforce the format
18 to the nicknames regardles whether there are multiple nicknames
19 or not. This configurable formatting was employed to flexibly
20 support accessing multiple nicknames from the user interface.
21 The userinterface can now set the nicknames to what ever format
22 they prefer. Affected file lib/silcclient/silcapi.h.
24 Added function silc_client_nickname_format to the file
25 lib/silcclient/idlist.c. It performs the nickname formatting.
27 Added new field `hostname´ to the SilcClientEntry context.
28 It holds the hostname of the client. Affected file is
29 lib/silcclient/idlist.h.
31 * Irssi SILC Client sets the nicknames in nick@hostn format.
32 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
33 irssi/src/silc/core/silc-core.c.
35 The WHOIS printing now also shows both the real nickname and
36 the formatted nickname so that user knows how to access the
37 user if there are multiple same nicknames cached. Affected
38 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
39 printing formatting too to take the hostname now as a separate
40 argument. The Affected file is
41 irssi/src/fe-common/silc/modules-formats.[ch].
43 * Changed the silc_client_get_clients_local to accept the formatted
44 nickname as argument. It accepts the real nickname too but the
45 formatted nickname can be used to find the true entry from
46 multiple entries. Affected file lib/silcclient/silcapi.h and
47 lib/silcclient/idlist.c.
49 * Added nickname_format_parse field to the SilcClientParams.
50 It is a callback function provided by the application to parse
51 the nickname out of the formatted nickname string. The library
52 calls it to get the nickname from the formatted string. Since
53 the application generally knows better the format of the nickname
54 string it parses it instead of the library, even though library
55 encodes the formatted string. If the callback function is not
56 provided then the library will use the string as is. The
57 affected file is lib/silcclient/silcapi.h.
59 * All the nickname strings passed to the client library in
60 commands are now expected to be formatted nickname strings.
61 If the command does not support the formatted nickname string
62 it will assume that the sent string is the actual nickname.
63 Affected file lib/silcclient/command.c.
65 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
67 * Added public key authentication support to OPER and SILCOPER
68 commands in the client library. Affected file is
69 lib/silcclient/command.c.
71 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
73 * Changed the get_auth_methdod client operation to be asynchronous.
74 It can be async if the application resolves the authentication
75 method from the server during the negotiation. Added new
76 SilcGetAuthMeth completion callback that the application will
77 call after resolving the authentication method.
79 Added function silc_client_request_authentication_method that
80 the application can use to resolve the authentication method
81 from the server. Added also SilcConnectionAuthRequest callback
82 that the library will call after the server has replied. The
83 application can call this function if it does not know the
84 current authentication method.
86 Affected files are lib/silcclient/client.c and
87 lib/silcclient/silcapi.h.
89 * The Irssi SILC client now automatically resolves the authentication
90 method incase any configuration information is not present (and
91 currently there never is). The affected file is
92 irssi/src/silc/core/client_ops.c.
94 * Fixed public key authentication from the client library.
95 Affected file lib/silcclient/protocol.c. Changed also the
96 protocol specification about the public key authentication in
97 the connection authentication protocol. The actual data to be
98 signed is now computed with a hash function before signing.
100 * Fixed the public key authentication from the server as well.
101 Affected file silcd/protocol.c.
103 * Removed the mlock()'s from the memory allocation routines.
104 Affected file lib/silcutil/silcmemory.c. The ./configure does
105 not check anymore for the mlock(). Affected file is
108 * Fixed USERS command in server to allow the execution of the
109 command for private and secret channels if the client sending
110 the command is on the channel. Affected file silcd/command.c.
112 * Fixed silc_client_get_clients_local to return the clients
113 count correctly. It could return wrong value. Affected file
114 lib/silcclient/idlist.c.
116 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
119 types. The assembler optimizations seemed not to like 64-bit
120 data types. The assmebler optimizations thus are now enabled
121 also for BSD systems as opposed to only enable them for Linux.
123 * Do not check for threads at all on BSD systems. Affected
124 file configure.in.pre.
126 * Removed -n and -h options from the Irssi SILC Client since
127 they are not used in silc.
129 * Fixed the prime generation to assure that the first digit
130 of the generated random number is not zero since our conversion
131 routines does not like number strings that starts with zero
132 digit. If zero digit is seen the random number is regenerated.
133 This caused some corrupted RSA keys when the zero first digit
134 was met. Affected file lib/silcmath/silcprimegen.c.
136 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
138 * Fixed WIN32 configuration in the ./configure script.
139 Fixed to include xti.h on environments that has it.
140 Patches by Carsten Ilchmann and andrew.
142 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
144 * Changed the silc_id_create_client_id to be collision
145 resistant. It is now assured that there cannot be created
146 two same client ID's. I suspect that some weird bugs in
147 the server were actually caused by duplicate Client IDs.
148 Affected file silcd/serverid.[ch]. A router receiving
149 new ID now also assures and informs the sending server
150 if the ID caused collision.
152 * Changed the silc_id_create_channel_id to also assure that
153 there are no collisions.
155 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Statement about ignoring the Mutual Authentication flag when
158 performing rekey with PFS was a bit misleading. It is ignored
159 if it was set in the initial negotiation, it cannot be even
160 set in the rekey. Fixed in the ke-auth draft. Started the
161 new versions of the protocol drafts in the doc/.
163 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
165 * Fixed a bug in silc_client_command_identify_save when saving
166 new channel information. The channel name was no duplicated
167 and caused crash on exit. Affected file is
168 lib/silcclient/command_reply.c.
170 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
172 * Fixed the getkey command handling in the server. Send just
173 empty OK reply to the sender if the key could not be fetched
174 (but everything else was ok, like the key just was not available).
175 Changed the public key parameter to optional in the protocol
176 specs so that empty OK reply can be sent. Affected file
179 Added a message to Irssi SILC client to tell to user if the
180 server did not return a public key.
182 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Fixed a channel key regeneration bug. It registered new
185 timeout tasks exponentially until all system resources were
186 used. Affected file silcd/server.c.
188 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Added the SILC Document generator to the scripts/silcdoc.
191 It can be used to generate the Toolkit Reference Manual out
192 of the source tree. Internally it will also use the RoboDoc
193 generator now imported in util/robodoc.
195 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
197 * Added couple of return's in rekey protocol if error orccurred
198 during the protocol. The execution must be terminated.
199 Affected file silcd/protocol.c. Also, terminate the protocol
202 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
204 * The client's Client ID was created initally from the wrong
205 nickname (it could have been in format nick@host) in the
206 silc_server_new_client. Affected file silcd/packet_receive.c
208 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
210 * Added some SILC_LOG_ERROR's to various error conditions
211 if client could not be added to ID cache. Affected files
212 silcd/packet_receive.c and silcd/server.c.
214 * When client's sock->user_data is freed, NULL also the
215 client->router and client->connection pointers. Added check
216 for these pointers being NULL to various places around the
217 code. Affected file silcd/server.c.
219 * Added client->data.registered == TRUE checks to various
220 places around the code to assure that unregistered client's
221 are not handled when it is not allowed. Affected file
224 * Added `bool registered' fields to all
225 silc_idlist_[server|client]_get_* routines to indicate whether
226 the fetched client needs to be registered or not. Affected
227 file silcd/idlist.[ch].
229 * Add your own entry as registered to the ID cache in the
230 server. Affected file server.c.
232 * Fixed a bug in silc_server_new_server. The SilcServer was
233 set as the new server's context instead of SilcServerEntry.
234 This naturally caused some weird bugs.
236 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
238 * Do not delete the channel rekey task when adding it
239 for in silc_server_create_channel_key.
241 * Changed the silc_server_create_channel_key to return
242 TRUE or FALSE to indicate the success of the channel key
245 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
247 * Fixed MSVC++ project files and added missing files to
248 Makefiles under win32/.
250 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
252 * Do not add TCP_NODELAY flag if the operating system
253 does not have it defined. Affected files are
254 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
256 * Fixed buffer overflow from Irssi SILC Client. Affected
257 file irssi/src/fe-common/core/themes.c.
259 * Fixed double free in client library in the file
260 lib/silcclient/client.c when disconnecting from server.
262 * Applied double free patch from cras to Irssi SILC client.
263 Affected files irssi/src/core/[modules/expandos].c
265 * Fixed the disconnection handling to Irssi SILC Client.
266 The application must call silc_client_close_connection
267 in ops->connect client operation in case of failure of
268 the connection. Affected file is
269 irssi/src/silc/core/client_ops.c.
271 * Do not set sock->protocol to NULL in the function
272 silc_client_close_connection after executing the protocol's
273 final callback since the sock might not be valid anymore.
274 Affected file lib/silcclient/client.c.
276 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
278 * Do not enable SILC_THREADS if the linking with libpthread
279 did not happen. Affected file configure.in.pre.
281 * Added notion to protocol specification that server must
282 verify the sent authentication payload with CMODE when
283 setting the channel founder key. Implemented it to the
284 server. Affected file silcd/command.c.
286 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
288 * Added _EXTRA_DIST SILC distribution variable to the
289 distributions file. It is used to conditionally add extra
290 files or directories to the specific distribution. Affected
291 files ./prepare, Makefile.am.pre and distributions.
293 Removed the `_' from the start of the distribution names.
296 * Added README.WIN32 for instructions to compile the Toolkit
299 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
301 * Fixed a double free in disconnection in the server. Affected
302 file is silcd/server.c.
304 * Fixed the lib/silcske/groups.c to work now also with GMP
305 MP library. The string conversion did not work when using
306 specific base and the base is indicated in the string as well.
308 * Created win32/ directory which now includes MSVC++ specific
309 stuff so that toolkit (DLLs) may be compiled with MSVC++.
310 It will appear only in the toolkit distribution
312 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
314 * Changed the key material distribution function in case when
315 the hash output is too short. The data is now concatenated
316 a bit differently than it used to. Made the change to the
317 SKE protocol specification.
319 * Added better GMP detection to configure.in.pre. A patch
322 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Fixed a minor bug in SKE that might cause some problem on
325 some platforms. Affected file lib/silcske/silcske.c.
327 * Added the cookie checking for initiator in the SKE. It checks
328 that the responder returns the sent cookie unmodified. The
329 affected file is lib/silcske/silcske.c. Added new SKE
330 error type INVALID_COOKIE that can be sent during the
331 negotiation. Fixed some memory leaks as well.
333 * Added the "invalid cookie" error message to Irssi SILC client's
336 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
338 * Added `task_max' field to the SilcClientParams to indicate
339 the maximum tasks the scheduler can handle. If set to zero,
340 default values are used. Affected file lib/silcclient/silcapi.h.
342 * Fixed memory leaks in silc_client_close_connection. Affected
343 file lib/silcclient/client.c.
345 * Added silc_client_del_client_entry to client library to free
346 all memory of given client entry. Affected file is
347 lib/silcclient/idlist.[ch].
349 * Added new functions silc_client_del_channel and
350 silc_client_del_server to delete channel and server entries.
351 Affected file lib/silcclient/[silcapi.h/idlist.c].
353 * Removed silc_client_del_client_by_id from silcapi.h.
355 * Fixed the INFO command to return the server's own info
356 correctly when querying by Server ID. Affected file is
359 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
361 * Removed the non-blocking settings in WIN32 code in the
362 silc_sock_[read/write] and added SleepEx instead. Affected
363 file lib/silcutil/win32/silcwin32sockconn.c. The availability
364 of input data is now checked with FIONREAD and ioctlsocket.
366 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
368 * Call silc_schedule_task_del_by_context in the
369 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
370 Affected file lib/silccore/silcprotocol.c.
372 * Call silc_protocol_cancel for active protocols in the
373 silc_server_close_connection if the funtion
374 silc_server_free_sock_user_data has not been called.
375 Affected file silcd/server.c.
377 * Generic tasks cannot be deleted using the del_by_fd
378 task deleting function since generic tasks does not match
379 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
381 * Added a notion to SILCOPER help file that the SILCOPER works
382 only on router server, not on normal server.
384 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
386 * Added for WIN32 support for the new scheduler as well.
387 Affected file lib/silcutil/win32/silcwin32schedule.c.
389 * Fixed the SHA1 implementation to work on various platforms.
391 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
394 API. It is part of the scheduler now. Everything else is
395 as previously but some functions has changed their names.
396 Checkout the lib/silcutil/silcschedule.h for the interface.
397 Updated all applications to use the new interface. Affected
398 files are lib/silcutil/silcschedule.[ch].
400 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Found a bug in the SKE implementation. The HASH value,
403 specified by the protocol, was not computed correctly. The
404 public key of the responder was not added to the computation
405 even though it is mandatory. Affected file lib/silcske/silcske.c.
406 This unfortunately causes incompatibilities with older
409 * Added WIN32 specific network init and uninit functions:
410 silc_net_win32_init and silc_net_win32_uninit to init and uninit
411 the Winsock2. Affected file lib/silcutil/silcnet.h and
412 lib/silcutil/win32/silcwin32net.c.
414 * Set the socket always to nonblocking mode on WIN32 after
415 reading data or writing data. Affected file is
416 lib/silcutil/win32/silcwin32sockconn.c.
418 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
420 * Fixed various compilation problems under WIN32. Affected
421 files lib/silcutil/win32/silcwin32thread.c and
422 lib/silcutil/win32/silcwin32schedule.c.
424 * Removed all _internal.h #includes from public header
425 files. Internal headers must never be included from
428 Removed also the lib/silcske/payload_internal.h file.
430 * All include files that may be needed (public and some others
431 included by the public headers) by application developers are
432 now copied to the ./includes directory. It does not copy any
433 internal headers. Affected file Makefile.defines.pre and all
434 Makefile.am's under lib/ and subdirs.
436 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
438 * Do not change the ~/.silc directory's permissions automatically.
439 Affected file irssi/src/silc/core/clientutil.c.
441 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Do not cancel the protocol in silc_server_close_connection
444 it might cause recursion. Now cancelled in the function
445 silc_server_free_sock_user_data. Affected file silcd/server.c.
447 * Fixed the silc_server_remove_clients_by_server to regenerate
448 the channel keys correctly finally. Added also new function
449 silc_server_remove_clients_channels to actually do it.
450 Affected file silcd/server.c.
452 * Fixed the silc_server_new_channel to not crash by giving
453 wrong router to the new channel. Affected file is
454 silcd/packet_receive.c.
456 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
459 which is given as argument to the silc_client_alloc now.
460 It can be used to configure the client and set various parameters
461 that affect the function of the client.
463 * The USERS command in server did not check whether the channel
464 is private or secret. Affected file silcd/command.c.
466 * Added new argument to the USERS command in protocol specification.
467 The USERS command now can take the channel name as argument
468 as well. Added support for this in client and server and
469 updated the protocol specs.
471 * Completed the GETKEY command in client. It can be now used
472 to fetch also servers public key not only some clients.
473 Affected files lib/silcclient/command[_reply].c.
475 * Added silc_client_get_server to return server entry by the
476 server name. Affected files lib/silcclient/silcapi.h and
479 * Redefined the IDENTIFY command in protocol specification to be
480 more generic. It now can be used to query information about
481 any entity in the SILC Network, including clients, servers and
482 channels. The query may be based either the entity's name
483 or the ID. Added support for this in both client and server.
485 Affected files silcd/command.c and lib/silcclient/command.c
488 * Optimized the WHOIS and WHOWAS commands in the server. Removed
489 the _from_client and _from_server functions. Affected file
492 * Added silc_client_get_channel_by_id_resolve to the file
493 lib/silcclient/silcapi.h to resolve channel information by
494 its ID. Added also silc_client_get_channel_by_id that
495 does not resolve it from the server.
497 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Added SilcServerEntry context into the client library
500 to represent one server. The INFO command now allocates
501 these to save the resolved server info. For now on the
502 client library will also keep information about servers,
503 connected and resolved with INFO.
505 The INFO command now allocates the SilcServerEntry context
506 and saves the server info there. The COMMAND_REPLY in
507 the INFO now returns the parameters to application in
508 same order as defined in the protocol specification.
510 The entries are cached in the client->server_cache.
512 * The INFO command is now issued after received the Client ID
513 from the server. Affected file lib/silcclient/client.c.
515 * The CMODE_CHANGE notify may now return also an SilcServerEntry
516 to the application as the mode changer might be server.
517 It is guaranteed that NULL is not returned anymore to the
518 application. Affected file lib/silcclient/client_notify.c.
520 The ID Type is now also passed to the application so that
521 it can check whether the returned entry is SilcClientEntry
524 Added new function silc_client_get_server_by_id to return
525 the server entry by ID. Affected files are the
526 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
528 * Do not create the channel in the Irssi SILC Client when issuing
529 the JOIN command but when received the sucessful JOIN command
530 reply. Otherwise the channel might get created even though we
531 could not join it. The Affected file is
532 irssi/src/silc/core/[silc-channels.c/client_ops.c].
534 * Fixed a channel joining bug in router. The router must also
535 check the channel modes, invite and ban lists etc. when serving
536 the JOIN command sent by normal server. Affected file is
537 silcd/command.c. The router now resolves the client's
538 information from the server who sent the JOIN command if it
539 does not know it, and processes the JOIN command only after
542 * Changed the SilcCommandCb to take new argument; void *context2.
543 Affected file lib/silccore/silccommand.h
545 The second argument in the command callbacks in the server now
546 includes the SilcServerCommandReplyContext if the command was
547 called as pending command callback from the command reply.
548 Otherwise it is NULL. When called as pending the status of the
549 command reply will be checked and if it was erronous the
550 error will be sent to the original sender of the command.
551 This way the client always receives the error messages even
552 though the server was actually the one who received the error
553 when it resent the command to router, for example. Affected
554 files silcd/command[_reply].[ch].
556 * Fixed sending WHOWAS command's error message to client if
557 the requested client could not be found. It was missing.
560 * Changed the CMODE and CUMODE commands reply arguments in the
561 protocol specification. The Channel ID is now sent in both
562 of the commands to identify the channel. Implemented this
563 new feature to the client and server. Affected files
564 lib/silcclient/command_reply.c and silcd/command.c.
566 * Made better checks for invite and ban lists in the JOIN
567 command in server. Affected file silcd/command.c.
569 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
571 * The server now performs the incoming host IP/DNS lookup
572 using the silc_socket_host_lookup and thus does not block
573 the server anymore. Affected file silcd/server.c.
575 * Completed the multi-thread support for SILC Scheduler in
576 the lib/silcutil/silcschedule.c.
578 * Fixed the configure.in.pre to detect the pthread correctly
581 * Fixed a deadlock in silc_task_queue_wakeup in the file
582 lib/silcutil/silctask.c.
584 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Added new function silc_schedule_wakeup that is used in
587 multi-threaded environment to wakeup the main thread's
588 schduler. It needs to be used when a thread adds a new task
589 or removes a task from task queues. After waking up, the
590 scheduler will detect the task queue changes. If threads
591 support is not compiled in this function has no effect.
592 Implemented the wakeup mechanism to both Unix and WIN32
593 systems. Affected files are lib/silcutil/silcschedule.[ch],
594 lib/silcutil/unix/silcunixschedule.c and the
595 lib/silcutil/win32/silcwin32schedule.c.
597 * Added new function silc_task_queue_wakeup to wakeup the
598 scheduler by the specified task queue. Affected file
599 lib/silcutil/silctask.[ch].
601 * The silc_socket_host_lookup_start now wakes up the scheduler
602 after adding the timeout task. Affected file is
603 lib/silcutil/silcsockconn.c.
605 * The silc_socket_host_lookup is synchronous now if the threads
606 support is not compiled in. However, the callback is still
607 called asyncronously through the scheduler, anyway. Affected
608 file lib/silcutil/silcsockconn.c.
610 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
612 * Added new function silc_socket_host_lookup to perform
613 asynchronous IP and FQDN lookups for the socket connection.
614 Affected files lib/silcutil/silcsockconn.[ch].
616 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
618 * Added SILC_MUTEX_DEFINE to define the mutex on environments
619 that may or may not compile the mutex support in.
621 Changed the silc_mutex_alloc interface. It allocates the
622 mutex now to the sent pointer and returns TRUE or FALSE.
624 Affected file lib/silcutil/silcmutex.h.
626 * Wrote the SILC Task Queue interface to support multi-threads.
627 Affected file lib/silcutil/silctask.[ch].
629 * Wrote the SILC Scheduler to support multi-threads. Affected
630 file lib/silcutil/silcschedule.c.
632 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Implemented the SILC Mutex API and SILC Thread API for WIN32
635 in lib/silcutil/win32/.
637 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
639 * Defined SILC Mutex API and SILC Thread API and implemented
640 them for Unix. Affected files are
641 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
642 lib/silcutil/unix/silcunixmutex.c and
643 lib/silcutil/unix/silcunixthread.c.
645 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Fixed the silc_server_remove_clients_by_server's channel
648 key re-generation. The hash table handling was incorrect
649 and would not work with many channels. Affected file is
652 * Fixed some memory leaks around the server code.
654 * Rewrote the silc_server_get_users_on_channel to support IPv6
655 based Client ID's. Affected file silcd/server.c.
657 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
658 specification. However, a separate document must be written
659 to define the detailed signing procedure and the payload
660 associated with the flag. Defined the flag to the
661 lib/silccore/silcchannel.h as well.
663 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Changed the dynamic tables to static size tables in the
666 lib/silccrypt/silchmac.c.
668 * Removed GCC dependencies from the code. A patch by cras.
670 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
672 * Do not show the error "Error receiving packet bla bla"
673 in server if it really was not an error (-2 means that reading
674 is pending). Affected file silcd/server.c.
676 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
678 * Fixed a possible crash in silc_server_remove_clients_by_server
679 in silcd/server.c. Fixed there also some memory leaks.
681 * Fixed the silc_idlist_replace_client_id. It could replace
682 wrong key in the hash table. Affected file silcd/idlist.c.
684 * Do not check whether there are global users on the channel
685 if the channel->global_users is FALSE. Affected functions
686 silc_server_remove_from_one_channel and
687 silc_server_remove_from_channels in silcd/server.c. Also,
688 do not check if the removed client is local as we can be
689 sure that global client was not removed from the channel
690 and checking for global users is not needed.
692 * The silc_server_remove_clients_by_server now re-generates
693 the channel keys correctly for those channels that had
694 clients removed from them. Affected file silcd/server.c.
696 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Found the reason of random crashes in the server. We weren't
699 ignoring the SIGPIPE signal (which can be sent in write())
700 and it crashed the server. Affected file silcd/silcd.c.
702 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Assure that sock->user_data is not NULL in the function
705 silc_server_packet_send in silcd/packet_send.c.
707 * Disconnect the remote connection if it could not be added
708 to any ID lists in the server. The affected file is
711 * Check in silc_server_packet_send[_real/dest] that the
712 socket is not disconnecting and ignore the data if it is.
713 Affected file silcd/packet_send.c.
715 * Define inline to __inline on native WIN32 compilation.
716 Affected file includes/silcwin32.h.
718 * Added some explicit type casts for inline code since MSVC
719 require them. Affected files lib/silcutil/silcbuffer.h,
720 lib/trq/silcdlist.h and lib/trq/silclist.h.
722 * Print warning in log files from now on if the packet
723 decryption fails. Affected file silcd/server.c.
725 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
727 * Changed the `say' client operation's interface to accept
728 new `type' argument to indicate the type of the message sent
729 by the library. The application may filter the library's
730 messages according the type. The affected file is the
731 lib/silcclient/silcapi.h.
733 * Added two new functions to lib/silcclient/silcapi.h:
734 silc_client_del_client and silc_client_del_client_by_id.
735 Affected file lib/silcclient/idlist.c.
737 * Moved the clientincludes.h from includes/ to silc/ and
738 serverincludes.h from includes/ to silcd/.
740 * The modes for the CMODE and CUMODE are now passed as
741 uint32 for application with COMMAND_REPLY. The affected
742 file is lib/silcclient/command_reply.c.
744 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * /WHOIS without arguments shows client's own information.
747 Affected file lib/silcclient/command.c.
749 * Changed PING to not accept any arguments. The specs
750 says that client can ping only the connected server so
751 requiring an argument is not needed. Affected file is
752 lib/silcclient/command.c.
754 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Fixed a fatal bug in private message sending and reception
757 encryption and decryption when using private message keys.
758 The implementation was incorrect and did not follow the
759 specification. It causd that some of the message were
760 lost since it did not use the sending and receiving keys
761 as the protocol suggests. This has been fixed and will cause
762 incompatibilities with older clients when sending private
763 message encrypted with private message keys. Affected files
764 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
765 and various other in Irssi SILC Client.
767 Added `responder' boolean argument to the functions
768 silc_client_add_private_message_key[_ske] to indicate when
769 the key is added as responder or initiator of the key
772 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Removed the silc_ske_check_version function and created
775 a SilcSKECheckVersion callback. Added also a function
776 silc_ske_set_callbacks that is now used to set all SKE
777 callbacks. The callback functions are not given to
778 the SKE functions anymore, but this function is used to
781 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
783 * Added `silc_version' argument to the silc_client_alloc
784 to define the version of the application for the library.
785 The library will use the version string to compare it
786 against the remote host's (usually a server) version
787 string. Affected file lib/silcclient/silcapi.h
789 * Added the KE protocol context to Key Agreement context
790 in client library so that we can abort the SKE if it
791 is in process when we get timeout. Affected file is
792 lib/silcclient/client_keyagr.c.
794 * Do not resolve the client ID forever if it returns in the
795 first time that such client does not exist. This was done
796 for example with private message. Affected file is
797 lib/silcclient/client_prvmsg.c.
799 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Do not add regex.h for WIN32. The affected file
802 includes/silcincludes.h.
804 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
805 not work yet 100%. It generates the DLL's automatically
806 when compiling with --with-win32 under cygwin.
808 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
810 * lib/contrib/regex.c is not compiled on WIN32.
812 * Added silc_net_get_socket_opt function to the
813 lib/silcutil/silcnet.h.
815 * Added includes/silcwin32.h for WIN32 specific includes
818 * Do not use ptime structure or any of the posix process
819 functions on WIN32 in lib/silccrypt/silrng.c.
821 * Added silc_gettimeofday to provide generic function
822 for struct timeval on all platforms. Added the function
823 to lib/silcutil/silcutil.h.
825 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Moved the lib/silccore/silcsockconn.[ch] to the utility
828 library as they clearly belong there. As a plus side we
829 can make the actual socket connection routines platform
832 Added also new generic function silc_socket_read and
833 silc_socket_write (that used to be silc_packet_[read/write].
834 The implementation of these are platform specific.
836 * Added WIN32 specific routines of silc_socket_[read/write]
837 to lib/silcutil/win32/silcwin32sockconn.c.
839 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Added preliminary support for native WIN32 compilation under
842 cygwin (using the -mno-cygwin option for GCC) to the
843 ./configure.in.pre. The --with-win32 now prepares the
844 compilation for native WIN32.
846 * Rewrote the SILC Scheduler interface in the file
847 lib/silcutil/silcschedule.h. The scheduler is now context
848 based and does not have anymore any global static scheduler.
849 Moved the Unix scheduler to the lib/silcutil/unix/ directory
850 and created lib/silcutil/win32 directory for WIN32 based
853 * Added Unix specific network routines to the
854 lib/silcutil/unix/silcunixnet.c and the old
855 lib/silcutil/silcnet.c includes now only generic routines.
857 Added WIN32 specific network routines to the
858 lib/silcutil/win32/silcwin32net.c.
860 * Added Unix specific utility functions from the
861 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
863 * Added WIN32 SILC Scheduler to the file
864 lib/silcutil/win32/silcwin32schedule.c. The code is of course
867 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
869 * Do not handle JOIN notify in the server if the target client
870 is not registered (idata->registered == FALSE). The affected
871 file is silcd/packet_receive.c.
873 * Update the nickrec->founder in event_cumode in the Irssi SILC
874 client. Affected file irssi/src/silc/core/silc-channels.c.
876 * Fixed the CUMODE_CHANGE notify handling in the server when
877 server and router are announcing their clients on channels.
878 Now the mode changes are saved and notified correctly. The
879 affected file is /silcd/packet_receive.c.
881 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
882 They really did not replace the cache entry in the ID Cache.
883 Now they do that. Affected file silcd/idlist.c.
885 * Fixed the KICK notify handling in the Irssi SILC client to
886 update the channel records so that the kicked client does not
887 appear to be on the channel. The affected file is
888 irssi/src/silc/core/silc-channels.c.
890 * Always update the conn->current_channel when executing command
891 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
893 * Fixed the KILL notify handling in Irssi SILC client to remove
894 the killed client on all channels.
896 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Fixed the silc_parse_command_line to remove extra spaces
899 from the start and end of the arguments. Affected file is
900 lib/silcutil/silcutil.c.
902 * Cancel and free any active protocol in the function
903 silc_server_close_connection. Affected file silcd/server.c.
905 * Cancel and free any active protocol in the function
906 silc_client_close_connction. Affected file is
907 lib/silcclient/client.c.
909 * Do not execute the KILL command for clients that are in
910 history (ie. they are not in the network). Affected file is
913 * Fixed KILL notify handling, client does not crash anymore.
914 Affected file irssi/src/silc/core/silc-channels.c.
916 * Reduced the default packet buffer size from 2048 to 1024 in
917 lib/silccore/silcpacket.c.
919 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
920 counter to the SKE context that is incresed when the SKE library
921 performs async operation outside the library. If the outside
922 process frees the SKE context and FREED status will be set
923 and the library will detect after the sync operation that the
924 libary is freed. The affected files are
925 lib/silcske/silcske[_status].[ch].
927 * Resolve the client entry information in the function
928 silc_client_channel_message to assure that NULL pointer is not
929 passed as client entry to the application. */
931 * Fixed the task timeout calculation to assure that there is
932 never negative timeouts. The affected file is
933 lib/silcutil/silcschedule.c.
935 * Fixed the channel user mode notification sending in server.
936 It was sent point-to-point to the router (or to server by router)
937 but it needs to be destined to a channel. The routines now
938 supports sending the channel user mode notifys to the channels
939 when announcing clients and channels. Affected files are
940 silcd/server.c and silcd/packet_receive.c.
942 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
943 It did not actually replace the old channel entry in the cache.
944 Affected file lib/silcclient/client_notify.c.
946 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Fixed a possible crash in silc_packet_send_prepare. It now
949 assures always that there is enough space in the buffer and
950 at the tail area of the buffer (for MAC).
952 Fixed the inbound buffer reallocation in silc_packet_read.
953 It was old code and did not handle the reallocation correctly.
956 The affected file is lib/silccore/silcpacket.c.
958 * Fixed buffer overflow in silc_parse_nickname in the file
959 lib/silcutil/silcutil.c.
961 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
963 * make install generates new server keys only if there is not
966 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
969 Added check that if the NOREPLY is set then we will not send
970 the away message. This avoids infinite loop of away messages
971 if both clients are away. The affected file is
972 lib/silcclient/client_prvmsg.c.
974 * Fixed client crash if /NICK was given without arguments.
975 Affected file lib/silcclient/command.c.
977 * Server does not send the invite list in INVITE command back
978 to the client if the list was not altered. Added this notion
979 to the protocol spec as well. Affected file silcd/command.c.
981 Fixed possible crash in INVITE command by checking the
982 value of silc_server_get_client_route command.
984 * Fixed the INVITE notify type handling. The arguments are now
985 taken in correct order and client does not crash. The affected
986 file is irssi/src/silc/core/silc-channels.c.
988 Removed the "Inviting xxx to channel" message from the
989 client library away and let the application handle it.
990 Affected file lib/silcclient/command.c. Added that message
991 to Irssi SILC client's message formats.
993 * Fixed CMODE command crash in client. It now checks the
994 amount of arguments correctly and does not crash. The affected
995 file is lib/silcclient/command.c.
997 * Do not create new channel automatically in silc_channels_join
998 but check whether the channel by that name already exists.
999 Affected file irssi/silc/core/silc-channels.c.
1001 * Do not send the SERVER_SIGNOFF to router if the disconnected
1002 entity was the router. Affected file silcd/server.c.
1004 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1005 SILC client as it was missing from there.
1007 Added the handling of the KICK notify to the Irssi SILC client
1008 as it was missing. Added "you have been kicked" message to
1009 Irssi SILC client's message modules formats.
1011 Added the handing of the KILL notify to the Irssi SILC client
1012 as it was missing. Added the kill message module formats
1015 The affected file is irssi/src/silc/core/silc-channels.c.
1017 * The router did not save the channel mode the server announced.
1018 Affected file silcd/packet_receive.c.
1020 * Fixed a possible crash in INFO command in server. If the
1021 server did not provide the server info it crashed. Affected
1022 file silcd/command.c.
1024 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Fixed the GETKEY command in the server to check also the
1027 global list. Otherwise the GETKEY would not work correctly
1028 in normal SILC server. Affected file silcd/command.c.
1030 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Fixed GETKEY crash, it crashed if the command did not succseed.
1034 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1036 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1037 is now real and not just an macro interface to GMP.
1039 Removed the entire GMP from the source tree and imported new
1040 NSS MPI library instead. Reason for removing GMP is that it is
1041 extremely large and compiles extremely slow. The NSS MPI
1042 is only a few files and compiles in less than 10 seconds.
1043 The speed is also about the same as GMP. The MPI is imported
1044 to lib/silcmath/mpi.
1046 If the system has GMP installed we will still use the GMP.
1047 If it is not then the NSS MPI will be compiled.
1049 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1051 * Merged a long nickname (127 characters long) crash bugfix from
1052 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1054 * Merged a freed memory reference bugfix from Irssi CVS tree.
1055 Affected file irssi/src/core/commands.c.
1057 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Added the server's public key sving and verification to the
1060 server when performing the SKE. This was missing and the
1061 remote server's (or router's) public key was accepted without
1062 checking whether we have it previously or trust it at all.
1063 Affected file silcd/protocol.c.
1065 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Check in the silc_server_timeout_remote if protocol is active
1068 and make sure that the protocol's final callback is called so
1069 that all memory if freed. Affected file silcd/server.c.
1071 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * silc_server_whois_send_reply crashed the server if the nickname
1074 was 127 characters long. Affected file silcd/command.c.
1076 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Added sanity check to the silc_server_new_client. If the hostname
1079 is provided inside username then check that the provided hostname
1080 really is the same as the resolved one. If the hostname was not
1081 resolved then check it from the public key. Affected file is
1082 silcd/packet_receive.c.
1084 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1085 if the server disconnected us and the connection is not valid
1086 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1088 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1089 the library to the lib/silcutil/silcutil.[ch].
1091 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Close log file after open. Affected file
1094 lib/silcutil/silclog.c.
1096 * Check whether sock == NULL in silc_client_send_packet and return
1097 if it is. Affected file lib/silcclient/silcclient.c.
1099 * Check rec->entry == NULL in the Irssi SILC Client before
1100 sending the channel message. Affecte file is
1101 irssi/src/silc/core/silc-servers.c.
1103 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Merged a splitted window bugfix from Irssi CVS tree. The
1106 affected file is irssi/src/fe-text/textbuffer-view.c.
1108 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1109 It did not print nickname.
1111 * Improved the distributions system a bit.
1113 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1116 irssi/src/fe-text/gui-window.c.
1118 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1119 to in-active server. The affected file is
1120 irssi/src/silc/core/client_ops.c.
1122 * Resolve the client in USERS command reply if the entry does
1123 not have username resolved. The affected file is
1124 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1125 command to WHOIS command to really resolve stuff. The USERS
1126 is not used any more in any critical section so WHOIS can
1127 be used even though it might be slower than IDENTIFY.
1129 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1132 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1134 * Changed the protocol API a bit more consistent in the
1135 lib/silccore/silcprotocol.[ch].
1137 * Changed the following headers to ROBODoc format:
1139 lib/silccore/silcpayload.h
1140 lib/silccore/silcprotocol.h
1141 lib/silccore/silcsockconn.h
1143 All core library headers are now formatted.
1145 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1147 * Fixed a bug in Irssi SILC client; do not show that you are
1148 server/router operator if you really are not. Affected file is
1149 irssi/src/silc/core/client_ops.c.
1151 * Renamed silc_command_free_payload to silc_command_payload_free.
1152 Affected file lib/silccore/silccommand.h
1154 * Added silcmath.h to include the prototoypes of various routines
1155 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1158 * Changed the following headers to ROBODoc format:
1160 lib/silccore/silcchannel.h
1161 lib/silccore/silccommand.h
1162 lib/silccore/silcid.h
1163 lib/silccore/silcidcache.h
1164 lib/silccore/silcmode.h
1165 lib/silccore/silcnotify.h
1166 lib/silccore/silcpacket.h
1167 lib/silcmath/silcmath.h
1169 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1171 * Added checking to the server code not to start the server if
1172 ciphers and stuff are not configured properly. Affected files
1173 silcd/serverconfig.[h] and silcd/server.c.
1175 * Changed the layout of the header files of the public interfaces
1176 in the SILC libraries. The new layout supports ROBODoc
1177 documentation tool (and some others) so that it is easy to create
1178 a library reference manual. All the other headers and source
1179 code must still follow the CodingStyle document. Also source
1180 code must not include these ROBODoc stuffs, only the headers.
1181 Furthermore, all public interface headers must now be named
1182 by using `silc' prefix, example: silcapi.h, silccipher.h.
1183 Some files were renamed due to this. All the other headers
1184 must not be used as public interfaces. I will update the
1185 CodingStyle document later. Changed following headers, so far:
1187 lib/silcclient/silcapi.h
1188 lib/silccore/silcauth.h
1189 lib/silccore/silcprivate.h
1190 lib/silccrypt/silcdh.h
1192 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Removed silc_client_packet_send_flush from the client library
1197 as it is not needed. Affected file lib/silcclient/client.[ch].
1199 * Added printing of message of unresolved authentication method
1200 to the Irssi SILC client. Added it to the module formats.
1201 Removed the same message from the client library.
1203 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1205 * Added new distribution feature, DISTLABEL. Every distribution
1206 can define own preprocessor label that can be used in the
1207 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1208 file distributions, acconfig.h.pre and prepare.
1210 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * Added Makefile.defines_int to include the actual definitions
1213 for Makefile.defines.in. Tested the new distribution system,
1214 created distributions and tested installation.
1216 * Added AWAY message printing to the Irssi SILC client. Added
1217 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1219 * Added SCONNECT command to call the SILC's CONNECT command.
1220 Cannot use CONNECT directly since Irssi uses that internally.
1221 Affected file irssi/src/silc/core/silc-servers.c.
1223 Added ACTION local command. It is same as ME command but takes
1224 the channel as mandatory argument.
1226 Rewrote some of the Irssi's help files to suite for SILC
1229 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Added Makefile.defines[.in] that should for now on be included
1232 in all Makefile.am file in the source tree. That file includes
1233 all common compilation definitions for SILC source tree.
1235 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Minor changes to the ./prepare script to change the package
1238 name according the distribution name to the configure.in.
1240 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Created new distribution system. Added file `distributions'
1243 that defines all the distributions that can be created out of
1244 the SILC source tree. The ./prepare script now reads that
1245 file to determine how to prepare the distributions. The
1246 first argument to the ./prepare is the name of the distribution
1247 and second is the version of the distribution. If given
1248 without arguments it creates the default (toolkit) distribution
1249 with the default version (defined in ./prepare).
1251 All Makefile.am files that are subject to the distributions
1252 are now named as Makefile.am.pre. These are ./Makefile.am
1253 and lib/Makefile.am. Others may be changed later.
1255 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1257 * Added invite list, ban list, some key management and connection
1258 error message printing to module formats in the Irssi SILC client.
1260 * Added new silc_client_set_away_message to set the away message
1261 that is back to the person who sent private message. The
1262 affected file lib/silcclient/silcapi.h and the
1263 lib/silcclient/client_prvmsg.c.
1265 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1267 * Fixed the private message sending in the Irssi SILC client,
1268 added local command KEY to the Irssi SILC client.
1270 Added key management and key agreement message formats to the
1271 irssi/src/fe-common/silc/module-formats.[ch].
1273 Added USERS (alias WHO) printing, server/router operator
1274 indication and LIST command printing to the module formats.
1276 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Fixed channel joining notify handling, cumode notify handling
1279 from Irssi SILC client.
1281 * Added SILC specific module-formats to the Irssi SILC client so
1282 that SILC specific message hilighting, colors etc is possible.
1283 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1285 Added channel mode, channel user mode, actions, notices,
1286 whois and whowas printing to the the module-formats.c.
1288 * Fixed a bug in channel deletion in the server. The channel
1289 is not left to the cache even if the channel founder auth mode
1290 is set when there are no users anymore on the channel. Affected
1291 file silcd/server.c.
1293 * The silc_net_localhost now resolves the entire hostname including
1294 the domain name. Affected file lib/silcutil/silcnet.c.
1296 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Changed the ask_passphrase client operation to be ascynchronous.
1299 It has now a completion callback and a context that the
1300 application must call after it has got the passphrase from
1301 the user. Affected files lib/silcclient/silcapi.h,
1302 lib/silcclient/protocol.c, lib/silcclient/command.c and
1305 Added SilcAskPassphrase callback that the application calls
1306 to deliver the passphrase to the library.
1308 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1309 The public key verification and especially a certificate
1310 verification is asynchronous procedure.
1312 Added new SILC_SKE_STATUS_PENDING status to indicate the
1313 request is pending and a callback will be called to finalize
1316 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1317 indicate that remote end did not send its public key (or
1318 certificate), even though we require it. Added check for this
1319 condition in the SKE. This was a security bug, now fixed.
1321 Defined new SilcSKEVerifyCbCompletion callback that is called
1322 when the verification process is completed.
1324 The affected files lib/silcske/silcske_status.h and
1325 lib/silcske/silcske.[ch].
1327 * Changed the verify_public_key client operation to be async
1328 as well. Defined SilcVerifyPublicKey callback that is used to
1329 indicate the success of the public key verification process.
1331 Changed the server and client to use the new async client
1334 * Changed the Irssi SILC client's internal scheduler to be called
1335 twice as many times as it used to be. As a result the client
1336 should be a bit faster now. Affected file is
1337 irssi/src/silc/core/silc-core.c.
1339 * Added support to Irssi SILC client of asynchronous public key
1340 verification and passphrase inquiry. Affected file is
1341 irssi/src/silc/core/silc-core.c.
1343 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Do not say "You have left channel %s" in client library.
1346 Moved it to the application. Affected files are
1347 lib/silcclient/command.c and silc/client_ops.c.
1349 * Fixed silc_client_get_clients. Command context was not
1350 duplicated and was freed memory in the callback. Affected
1351 file lib/silcclient/idlist.c.
1353 * Do not say "you are now talking..." on JOIN command in the
1354 client library. The appliation must handle it.
1356 * Do not say ".. changed topic to" in command reply in the
1357 client libary. The application must handle it.
1359 * Fixed TOPIC command sending in the client library.
1361 * Fixed a memory leak in silc_client_command_free in the file
1362 lib/silcclient/command.c.
1364 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1366 * Imported a modified version of Irssi client to the source tree.
1367 The Irssi will be used to create a new client called
1368 Irssi SILC. Imported to irssi/.
1370 Added silc_core_init_finish function to the Irssi. Affected
1371 file irssi/configure.in.
1373 A lot changes in the Makefile.ams around the irssi tree.
1375 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Do not rehash if the new size is same as the old size of the
1378 hash table, in the silc_hash_table_rehash*. The affected file
1379 lib/silcutil/silchashtable.c.
1381 * Replaced hash_table_del_by_context calls from the server
1382 (when channel->user_list and client->channels) to the
1383 hash_table_del as it is sufficient and faster.
1385 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1387 * Added silc_hash_table_list, silc_hash_table_get and the
1388 SilcHashTableList structure to provide an alternative way to
1389 traverse the hash table. The affected files are
1390 lib/silcutil/silchashtable.[ch].
1392 * Changed the server's idlist routines to use the hash table
1393 routines to optimize the code.
1395 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Replaced the client entry's `channel' list and channel entry's
1398 `user_list' list to hash tables for optimized lookup. Changed
1399 the code to use the hash table interface around the code.
1400 Affected file lib/silcd/idlist.[ch].
1402 * Added `auto_rehash' boolean argument to the function
1403 silc_hash_table_alloc to indicate whether the hash table should
1404 auto-rehash when it thinks is appropriate time. It will
1405 increase the hash table size if the there is twice as much
1406 entries in the table than the size of the table, and will
1407 decrease the size if there are twice as less entries than
1408 the size of the table.
1410 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1414 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * silc_idcache_purge_by_context deletes the entry now by context
1417 as it is supposed to do. Affected file lib/silccore/idcache.c.
1419 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1420 client is not anymore valid (WHOWAS givens the info) and not
1421 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1423 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Removed the `data' and `data_len' arguments from the ID Cache
1426 interfaces and added `name' argument. ID Cache does not handle
1427 anymore the binary data only a names associated with given ID.
1429 * When hashing a Client ID with silc_hash_id the entire ID is
1430 not hashed anymore, instead only the hash of the Client ID is
1431 hashed. This way we can access the Client ID from the cache
1432 with Client ID but with the hash of the ID (which is a hash of
1433 the nickname) as well without any difference in performance.
1435 Added also silc_idcache_find_by_id_one_ext to do one on one
1436 searching when we have the actual ID. Added also function
1437 silc_hash_client_id_compare. The affected files are
1438 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1440 * When hashing the name associated with a ID it is always done
1441 in lowercase. This way we can access the cache without worrying
1442 about case-sensitivity, even though, for example nicknames are
1445 * Fixed a bug in server with channel message sending. It put
1446 wrong ID type as destination ID. The affected file
1447 silcd/packet_send.c.
1449 * silc_idcache_del_by_context now deletes from all hash tables
1450 by context. Affected file lib/silccore/idcache.c.
1452 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Changed the client library to use the new ID Cache interface.
1455 Changes around the source tree.
1457 * Added silc_hash_table_rehash_ext to rehash with specific
1458 hash function. Affected file lib/silcutil/silchashtable.[ch].
1460 * Added silc_hash_string_compare to compare two strings in the
1461 hash table. Affected file lib/silcutil/silcutil.[ch].
1463 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Added new function silc_idcache_del_by_context into the
1466 lib/silccore/idcache.[ch].
1468 * Changed the server's ID list routines to use the new ID Cache
1469 interface. Changes around the source tree.
1471 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Added silc_hash_table_del[_by_context]_ext functions in to the
1474 lib/silcutil/silchashtable.[ch].
1476 Removed silc_hash_table_find_all* routines and added new
1477 silc_hash_table_find_foreach to replace them.
1479 Added silc_hash_table_replace_ext function as extended
1480 replacing function. Separated the simple hash table interface
1481 from the extended hash table interface in the file
1482 lib/silcutil/silchashtable.h.
1484 * Fixed minor bugs and changed it to use some of the new
1485 hash table functions in lib/silccore/idcache.c
1487 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Added new function silc_hash_table_find_all to return all keys
1490 in the hash table by the specified key. As the hash table is
1491 collision resistant it also makes it possible to have several
1492 duplicate keys in the hash table. This function may be used to
1493 find all of the keys from the hash.
1495 Added user_context arguments to the SilcHashFunction,
1496 SilcHashCompare and SilcHashDestructor to deliver user specified
1499 Added new fuctions silc_hash_table_find[_all]_ext to do
1500 extended lookup with specified hash and compare functions and
1501 specified user contexts.
1503 Added new function silc_hash_table_add_ext to add the key
1504 with specified hash function and user context.
1506 Added new function silc_hash_table_foreach to traverse all
1507 entrys in the hash table. Added SilcHashForeach callback
1510 Added new function silc_hash_table_del_by_context to delete
1511 the entry only if the context associated with the key matches.
1513 Affected files are lib/silcutil/silchashtable.[ch].
1515 * Removed silc_hash_[server/client/channel]_id and added just
1516 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1517 silc_hash_id_compare to compare two ID's using as the hash table
1518 comparison function. Added also silc_hash_data to hash
1519 binary data and silc_hash_data_compare to compare it.
1521 * Removed silc_idlist_find_client_by_hash as it is not needed
1522 anymore. Affected file silcd/idlist.[ch].
1524 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1525 to use internally the SilcHashTable. The new ID Cache is a lot
1526 faster than the old one. Some of the ID Cache interface was also
1527 rewritten and obsolete and stupid functions were removed.
1529 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1531 * Added entry_count field to the SilcHashTable to keep the number
1532 of the entries in the table. Implemented the function
1533 silc_hash_table_rehash. Added new function
1534 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1536 Fixed a minor bug in silc_hash_table_free.
1538 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1539 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1540 into the lib/silcutil/silcutil.[ch].
1542 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1544 * Implemented a collision resistant hash table into the
1545 lib/silcutil/silchashtable[ch]. See the header and the source
1546 for the SilcHashTable API.
1548 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1550 * Merged dotconf version 1.0.2 into lib/dotconf.
1552 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Do not compile anything in lib/silcsim/* if the SIM support
1555 is not enabled. The tree should now compile without problems
1558 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Compiled the SILC under cygwin. Compiled and tested briefly
1561 without problems. More tests needed. The SIMs didn't compile
1564 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1566 * Fixed possible crash in silc_get_username in the
1567 lib/silcutil/silcutil.c.
1569 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Fixed a va_arg in silc/client_ops.c.
1573 * Oops, RC5 routines were named AES and caused some problems
1574 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1576 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Added new SilcIDIP structure into the lib/silccore/id.h and
1579 replaced the old `ip' fields from all SILC ID's to that type.
1580 This is a step towards IPv6 support.
1582 The silc_id_get_len takes now the ID as an extra argument.
1583 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1584 both IPv4 and IPv6 based ID's.
1586 The affected files are lib/silccore/id.[ch] and other files
1587 around the tree using these routines.
1589 * Removed the ID length arguments in server from various
1590 silc_server_send_notify_* routines -> they are not needed
1593 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Fixed memory leak in silc_encode_pem_file in the file
1596 lib/silcutil/silcutil.c.
1598 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Check minor version as well in the SKE. Affected files are
1601 silcd/protocol.c and lib/silcclient/protocol.c.
1603 * Added --identifier option to the server so that an identifier
1604 can be when creating the public key for the server. Affected
1605 file is silcd/silcd.c.
1607 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1608 lib/silccrypt/silcpkcs.c.
1610 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Register default ciphers and stuff when using -C option with
1613 the server. Affected file sildc/silcd.c.
1615 * Put back the servers public key filename format, it is better
1616 than the new one. For now, the client keys are saved with the
1617 new filename format. The affected file silc/client_ops.c.
1619 * Implemented the Cipher API for the rest of the ciphers that
1620 did not implement it or implemented it the wrong way.
1622 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Register default ciphers and stuff when using the -S option
1625 in the client. Affected file silc/silc.c. Same also when
1626 creating new key pair with -C option.
1628 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1630 * Fixed the silc_verify_public_key client operation function to
1631 save the public keys differently. The fingerprint is now
1632 used as filename and not the hostname. This way also the
1633 client keys are saved uniquely and not with hostnames. The
1634 affected file is silc/client_ops.c.
1636 * Trimmed the silc_hash_fingerprint function to remove extra
1637 whitespaces from the end of the fingerprint. The affected
1638 file is lib/silccrypt/silchash.c.
1642 * Added silc_cipher_register_default function to register all
1643 default ciphers. It can be used when configuration files
1644 does not exist and the application does not want any specific
1645 ciphers in any specific order.
1647 The SilcDList is now used as silc_cipher_list dynamically
1648 allocated cipher list. Removed the static list all together
1649 and now all ciphers must be allocated to the dynamic list.
1650 The silc_cipher_alloc routine was changed to check only the
1653 All silc_cipher_* routines that used to return int returns
1656 The affected files lib/silccrypt/silccrypt.[ch].
1658 * The same thing was done to silc_hash_* as for silc_cipher_*
1659 routines. Affected files lib/silccrypt/silchash.[ch].
1661 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1662 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1663 Added also silc_pkcs_[un]register[_default] functions.
1664 Removed the data_context from the PKCS API.
1666 * Added silc_hmac_register_default function to register default
1667 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1668 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1669 to unregister all hmacs at once.
1671 * Register the default ciphers, hash functions, PKCSs and HMACs
1672 if client's configuration file does not exist. The affected
1675 * The client did not load the hash functions from the SIM
1676 modules at all. Added support for this. Affected file is
1677 silc/clientconfig.c.
1679 * When decoding public key with silc_pkcs_public_key_decode, check
1680 the supported algorithm only if PKCS are registered. Affected
1681 file lib/silccrypt/silcpkcs.c. The same was done with the
1682 silc_pkcs_private_key_decode.
1684 * Fixed the SILC List routines to keep the list always in order.
1685 It used to change the list's order when traversing the list but
1686 not it preserves the order. Affected file lib/trq/silclist.h.
1688 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * Added the client library to use the SilcSocketConnection's
1691 reference counter (by silc_socket_dup) to prevent the bug that
1692 the socket object may be freed underneath async operation.
1694 * The name resolv library checking fixes in the configure.in.pre.
1697 * Created new version of the protocol drafts for future
1698 development. The -03 drafts are the ones that will be changed
1699 in the trunk now and the -02 will remain as they are.
1701 * Send list of CUMODE notifys to the router when announcing
1702 the channel users to the router. Affected file silcd/server.c.
1703 If the router receiving channel founder CUMODE for a channel
1704 that already has channel founder it will send CUMODE notify
1705 to the sender to remove the channel founder rights from the
1706 announced client. Affected file silcd/packet_receive.c.
1708 * The CUMODE notify may now use Server ID as well as the entity
1709 who changes the mode. Updated protocool specs.
1711 * Updated INSTALL and README files.
1713 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * New web pages in the http://silc.pspt.fi. The pages was
1720 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Implemented the [DenyConnectin] config section in the server.
1723 Added silc_server_config_denied_conn to check whether incoming
1724 connection is denied. Affected file silcd/serverconfig.[ch].
1726 * Do not check the ports when checking the incoming configuration
1727 data if the port is 0, meaning any. Affected file is
1728 silcd/serverconfig.c.
1730 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Fixed buffer overflow in silc_string_compare in the file
1733 lib/silcutil/silcutil.c.
1735 * Fixed double free in silc_server_command_leave in the file
1738 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Fixed the version checking in the server. Affected file is
1743 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1745 * Fixed the configuration data fetching when accepting new
1746 connections in the server. Affected file silcd/server.c.
1748 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Added `sender_entry' argument to the function
1751 silc_server_packet_relay_to_channel so that we can check
1752 whether some destination actually belongs to the same route
1753 the sender belongs (ie, we must not resend the packet to the
1754 sender). Affected file silcd/packet_send.[ch].
1756 * Added `servername' field to the SilcClientEntry in the server
1757 to hold the name of the server where client is from. Affected
1758 file is silcd/idlist.h.
1760 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Moved the channel message encrypting in the router betwen
1763 router connections from silc_server_channel_message to the
1764 silc_server_packet_relay_to_channel since we want to check
1765 whether we have anybody channel before encrypting anything.
1766 Affected files silcd/packet_[receive/send].c.
1768 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Fixed the [AdminConnection] server config section to support
1771 multiple entries. Affected file silcd/serverconfig.c.
1773 * Added support into the server to check the validity of the
1774 incoming connection before executing any KE or authentication
1777 * The connection configuration is now saved to the KE and
1778 connection auth protocol contexts and not fetched anymore in
1779 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1781 * The local hosts listenning address and port is also resolved
1782 now when starting the server. We want to have the socket object
1783 to include the real address and port for the listener. Added
1784 new function silc_net_check_local_by_sock into the files
1785 lib/silcutil/silcnet.[ch].
1787 * Fixed a broadcast bug in server -> do not broadcast if we
1790 * Fixed a routing bug. Do not route broadcast packets ever.
1791 Broadcast packets must be processed always and not routed since
1792 they may be destined to some other host than yourself and thus
1793 would get routed without no good reason. Affected file is
1796 * Added function silc_server_config_is_primary_route to check
1797 whether primary router connection has been configured (a router
1798 configuration that we are initiating). If there is not, we
1799 will assume that there is only two routers in the SILC network
1800 and we will use the incoming router connection as our primary
1801 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1803 * Changed the order of the broadcasting. Broadcast _after_ the
1804 packet has been processed not before. Affected file is
1807 * Fixed a [ClientConnection] parsing bug. The port was never
1808 parsed correctly thus resulting to port 0. Affected file
1809 silcd/serverconfig.c.
1811 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1812 argument and did not set the broadcast packet flag. Affected
1813 file silcd/packet_send.c. Fixed same bug in the function
1814 silc_server_send_notify as well.
1816 * If we receive NEW_ID packet for our own ID in the server, ignore
1819 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1823 * Removed the nickname from the Private Message Payload.
1824 Updated the code and the protocol specs.
1826 * Updated protocol specs for submitting to the IETF.
1828 * Tweaked the Random Number Generator a bit. Affected file
1829 lib/silccrypt/silcrng.c. Exported a new function
1830 silc_rng_[global]_add_noise which can be used to add more
1833 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Do not parse packets with different timeout when protocol
1836 is active -> may cause problem with rekey. Affected file
1839 * When server receives signoff notify it must not create
1840 new channel key if the client is on any channels since the
1841 sender of the signoff notify will create it.
1843 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Added printing of error messages during SKE protocol from the
1846 failure packet sent by server during SKE. Affected file
1849 * Removed the client's failure_callback handling with timeout
1850 and handle it immediately when received.
1852 * The SKE library returned wrong type in SUCCESS and FAILURE
1853 packets. They must be 32 bit MSB not 16 bit MSB.
1855 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Ok, rewrote the logic of the re-key and now it seems to work.
1858 I tested it on high traffic with frequent re-keys without
1859 problems. Added hmac_receive (and renamed hmac to hmac_send)
1860 in SilcClientConnection in lib/silcclient/client.h and
1861 in SilcIDListData in silcd/idlist.h. Also, removed the
1862 SilcPacketParserContext's cipher and hmac fields as they are
1863 not needed anymore and actually caused some problems when
1864 the ciphers and hmac's changed underneath the packet parser.
1866 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1868 * If re-key protocol is active then process the incoming packets
1869 synchronously since we must assure that icoming packets encrypted
1870 with the old key is processed before the new keys is set to
1871 use. This is true other packets than for REKEY packets.
1872 Affected file silcd/server.c. The same was done to client library
1873 as well, affected file lib/silcclient/client.c.
1875 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Fixed bug in client and server to accept the force send if
1878 the packet is send from silc_[server/client]_packet_process
1879 function. Otherwise the packets are never delivered, oops.
1881 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Disable force sending of packets when REKEY protocol is active.
1884 We must assure that no packet is sent directly when rekey is
1885 performed. All packets must be sent through packet queue.
1886 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1887 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1888 function is silc_[server/client]_packet_send_real to check
1891 * Replaced the SIM paths from example config files to
1892 /usr/local/modules. Also, make install creates now
1893 /usr/local/silc/logs directory to hold all the SILC server
1896 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1898 * Made the configure.in.pre work on Solaris. Patch by salo.
1900 * Made all ciphers compatible with non-x86 machines. Defined
1901 CBC mode macros into lib/silccrypt/ciphers_def.h.
1903 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Fixed the make install.
1907 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * When MAC computation fails the silc_packet_decrypt returned 0
1910 even though it was supposed to return -1. Fixed this. The
1911 affected file is lib/silccore/silcpacket.c.
1913 * Do not replace the config files in /etc/silc (in make install)
1914 if they already exist. Affected file ./Makefile.am.
1916 * Do not send re-key packets immediately but through packet queue.
1917 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1919 * Changed silc_net_check_host_by_sock to return FALSE if the
1920 IP/DNS could not be resolved. Though, it returns the IP address
1921 now even if it could not resolve it (but returns also FALSE).
1922 Affected file lib/silcutil/silcnet.[ch].
1924 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Added silc_pkcs_decode_identifier to decode the public key's
1927 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1928 Added also silc_pkcs_free_identifier. Added also new context
1929 SilcPublicKeyIdentifier.
1931 * Added -S option to the silc client. It is used to dump the
1932 contents of the specified public key file.
1934 * Changed the PKCS api to return the public key length when
1935 setting the public key.
1937 * Fixed a fatal bug in the public and private key file loading.
1938 Affected file lib/silccrypt/silcpkcs.c.
1940 * Execute the packet parsing for client with zero (0) timeout
1941 if the protocol is active. Affected file silcd/server.c.
1943 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Made the key generation options to the silcd program. Added
1946 -C option, equivalent to client's option.
1948 * Added new [ServerKeys] config section to the server. It
1949 configures the server's public and private key.
1951 * Defined generic Public Key Payload into the protocol
1952 specification to send specific type of public keys and
1955 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1956 public key or certificate.
1958 * Implemented the GETKEY command to the server and to the
1959 client library and on user interface.
1961 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Made preliminary `make install' work.
1965 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Added SilcServerRekey context into silcd/idlist.h.
1969 * Added the PFS support as defined in the specification to the
1970 SKE protocol. Affected files lib/silcske/*.c.
1972 * Added `ske_group' field to the SilcServerRekey context to hold
1973 the number of the SKE group that is used with PFS in re-key.
1974 Affected file silcd/idlist.h.
1976 * Added PFS re-key support to the server. Affected file is
1979 * Added silc_protocol_cancel to cancel execution of the next
1980 state of the protocol. Affected file is
1981 lib/silccore/silcprotocol.[ch].
1983 * Added the re-key support with and without PFS to the client
1984 library. Re-key is performed once in an hour, by default.
1986 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1987 Added silc_client_rekey_callback and silc_client_rekey_final.
1988 Affected files are lib/silcclient/protocol.[ch] and
1989 lib/silcclient/client.[ch].
1991 * Removed the `hmac_key' and `hmac_key_len' fields from the
1992 SilcClientConnection structure; not needed. Affected file is
1993 lib/silcclient/client.h.
1997 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Do not ask whether user wants to use the negotiated private key
2000 for private messages, just use it. Affected file is
2001 silc/local_command.c.
2003 * Added `send_enc_key' and `enc_key_len' fields to the
2004 SilcIDListData structure since they are needed in the re-key
2005 phase. Affected file is silcd/idlist.[ch].
2007 * Implemented the simple re-key protocol into the server.
2008 Affected files silcd/server.c and silcd/protocol.[ch]. The
2009 re-key will be performed once in an hour, by default.
2011 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2012 Added silc_server_rekey, silc_server_rekey_callback and
2013 silc_server_rekey_final.
2015 * Removed Tunneled flag from the protocol. Updated the code
2016 and the specifications.
2018 * Adde `pfs' field to the SilcIDListData to indicate whether
2019 the PFS is to be performed in the re-key. Affected file is
2022 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2025 int64 of at least the xintXX size. If void * is less that 4
2026 bytes uint32 * will be used. Defined bool as boolean.
2028 * Changed _ALL_ unsigned long and unsigned int to uint32,
2029 unsgined short to uint16 in the source tree.
2031 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2032 not handle clients that has entry->data.registered == FALSE.
2033 They are not in the network anymore. Affected file is
2036 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Implemented the sending of the SERVER_SIGNOFF notify in the
2039 server. Affected file is silcd/server.c.
2041 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2042 Added also silc_notify_payload_encode_args into the
2043 lib/silccore/silcnotify.[ch].
2045 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2046 Affected file silcd/packet_receive.c.
2048 * Implemented the SERVER_SIGNOFF notify handling in the client
2049 library. Affected file lib/silcclient/client_notify.c. Also,
2050 implemnted the printing of the SERVER_SIGNOFF info to the
2051 application. Affected file silc/client_ops.c.
2053 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2054 if the deleting was successful. Affected file silcd/idlist.[ch].
2056 * Added support for public key authentication in the connection
2057 authentication protocol in the client library. Affected file
2058 lib/silcclient/protocol.c.
2060 * Changed the server's silc_idlist_get_clients_by_* interface
2061 to support already allocated array so that new entries may be
2062 added to pre-allocated array. Affected file silcd/idlist.[ch].
2063 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2064 and command replies.
2066 * All command reply functions in the server now calls the
2067 pending command callback even if error occured. This way the
2068 error will be delivered to the client as well. Affected files
2069 silcd/command.c and silcd/command_reply.c.
2071 * Fixed INFO command to return local server's info if no server
2072 was provided. Affected file lib/silcclient/command.c.
2074 * Removed RESTART command for good. Updated the code and the
2077 * Rewrote parts of the task system. It is a bit simpler now.
2078 Removed unsued task priorities. The affected files are
2079 lib/silcutil/silctask.[ch].
2081 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Moved the USERS printing from the library to the application.
2084 Affected files lib/silcclient/command.c and silc/client_ops.c.
2086 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added channel key re-key support. The re-key is perfomed
2091 only by the router and is done once in an hour. Added `rekey'
2092 field to the SilcChannelEntry in the server. Affected files
2093 silcd/server.c and silcd/idlist.h.
2095 * Added silc_task_unregister_by_context into the file
2096 lib/silcutil/silctask.[ch].
2098 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Added SILC_UMODE_GONE mode to indicate when the client is not
2101 present in the SILC network. Added also support to the local
2102 command AWAY that will set this mode. Added support of showing
2103 "xxx is gone" in WHOIS command. The USERS command shows the
2104 gone status as well.
2106 * Fixed setting server and router operator privileges in the
2107 server's UMODE command. Affected file silcd/command.c.
2109 * Merged the SKE KE1 and KE2 payloads into one payload. The
2110 new KE payload is equivalent to the old KE2 payload.
2112 Cleaned up the SKE Start Payload parsing. It now uses the
2113 simple buffer unformatting to do the parsing. A lot faster
2116 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2117 to the SKE that is used to indicate whether both of the SKE
2118 parties should perform authentication. By default only the
2119 responder performs authentication. By setting this flag also
2120 the initiator must do authentication. By default it is unset
2121 since in normal SKE case, client to server connection, only
2122 the responder should do authentication. When doing SKE between
2123 two clients both should perform authentication. Updated the
2124 code and the protocol specs.
2126 * A little fix to IDENTIFY command in the server. Search the
2127 client first by hash not nickname. Affected file is
2130 * Fixed the silc_client_close_connection to support closing
2131 the client to client connections wihtout deleting too much
2132 data. Affected file lib/silcclient/client.c.
2134 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2135 are received if protocol used to be active but is not anymore
2136 the application would crash due to NULL pointer dereference.
2137 Affected files silcd/server.c and lib/silcclient/client.c.
2139 * Added `hash' field to the SilcClientConnection to include
2140 the hash function negotiated in the SKE protocol.
2142 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2143 to set the channel founder authentication data. A client can
2144 claim the founder rights later by providing the authentication
2145 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2146 This way the channel founder can regain the channel founder
2147 privileges even it is left the channel. This works only on
2148 local server and the client must be connected to the same
2149 server to be able to regain the founder rights. Updated the
2150 protocol specs accordingly.
2152 Added support to the CMODE command in the client to set the
2153 founder auth data. Read the README to see how to set it.
2155 Added support to the CUMODE command to claim the founder
2156 rights. Read the README to see how to do it.
2158 Added support for the founder authentication to the Channel
2159 Entry in the server. Affected file silcd/idlist.h.
2161 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2162 server's CMODE command. Affected file silcd/command.c.
2164 * Added the following new functions into lib/silccore/silcauth.[ch]:
2165 silc_auth_get_method and silc_auth_get_data.
2167 * The server now saves the remote hosts public key to the
2168 SilcIDListData pointer. Affected file silcd/protocol.c.
2170 * The normal server now does not remove the channel entry from
2171 the cache if the founder authentication data is set. It used
2172 to remove it if the founder was the last one on the channel on
2173 the server and left the channel. The auth data is saved and
2174 if the channel is re-joined later the old entry is used with
2175 the old auth data. Affected files silcd/command_reply.c and
2178 * Removed the `pkcs' field from the SilcIDListData structure
2179 in the server; it is not used. Affected file silcd/idlist.h.
2181 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Fixed packet processing on slow links. Partial packets were
2184 never re-processed because the incoming data buffer was cleared
2185 by the application. Application must not directly clear the
2186 sock->inbuf, the packet processing routines handle it. Fixed
2187 this in client library and in server.
2189 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Fixed the WHOIS and IDENTIFY send reply function to really
2192 check whether to send list or just one entry. Affected file
2195 * Cleaned up the LEAVE command's channel key distribution. The
2196 affected file silcd/command.c.
2198 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2199 can enforce the channel mode as well. In that case the ID
2200 includes the ID of the server. The code now enforces the
2201 mode change if the router have different mode than the server.
2203 * The notify client operation with CMODE_CHANGE notify can now
2204 return NULL client_entry pointer if the CMODE was not changed
2205 by client. Application must check for this.
2207 * Added <Server ID> argument to INFO command to support server
2208 info fetching by Server ID.
2210 * Added silc_server_announce_get_channel_users to get assembled
2211 packets of channel users of the specified channel. Affected
2212 file silcd/server.[ch].
2214 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2215 was freed underneath the ID Cache.
2217 * Re-announce clients when the server received CHANNEL_CHANGE
2218 notify from the router. Affected file silcd/packet_send.c.
2220 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2223 crashed since it did not handle the fact that there is no cipher
2224 called "3" and didn't check the error condition. Now fixed.
2226 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2227 flag. It can be used to send message requests.
2229 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Implemented the RESTART command in the client.
2233 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2234 notice type messages. Added notice printing to the user
2237 * The channel keys are not re-generated if the channel's mode
2238 is PRIVKEY, ie private key on the channel exists. Affected
2239 files silcd/server.c and silcd/command.c.
2241 * Fixed a little bug in channel message delivery when channel
2242 private keys are set in the server. Affected file is
2243 silcd/packet_send.c.
2245 * Changed the setting on channel->on_channel = TRUE from the
2246 silc_client_save_channel_key to the JOIN command reply. The
2247 key payload is not received if the private channel key is set.
2248 Affected file lib/silcclient/command_reply.c and the
2249 lib/silcclient/client_channel.c.
2251 * When the CMODE_CHANGE notify is sent and the channel private
2252 key mode is removed the channel key must be re-generated in
2253 other cells as well. Added this support for the router in the
2254 silcd/packet_receive.c.
2256 * Added new local command NOTICE to send notice message on
2257 channel. Affected file silc/local_command.[ch].
2259 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Added new local command ME to the client. It is used to send
2262 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2263 some action. Affected file silc/local_command.[ch].
2265 * Changed channel_message and private_message client operations
2266 to deliver the message flags to the application. Added also
2267 the `flags' arguments to the silc_client_send_channel_message
2268 and silc_client_send_private_message functions. Affected file
2271 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Redefined the Private Message Payload to support private message
2274 keys and to support the new private message flags. Updated
2275 the protocol specs. Flags makes it possible to have for example
2276 CTCP style messages.
2278 * Added new type SilcPrivateMessagePayload and defined an API
2279 for it in the lib/silcclient/silcprivate.[ch].
2281 * Tested private message private keys successfully. Tested the
2282 private message key set, unset and list commands with the new
2285 * Redefined the Channel Message Payload to include the channel
2286 message flags (equal with private message flags) to support
2287 for example CTCP style messages.
2289 * Defined some of the message (for channel and private message)
2290 flags. Updated the protocol specs and added the flags to the
2291 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2293 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Added SilcKeyAgreementStatus type to the key agreement routines
2296 to indicate the current status and error if one occured.
2297 The status types are defined in the lib/silcclient/silcapi.h.
2299 * Added new local command KEY that is used to set and unset private
2300 keys for channels, set and unset private keys for private messages
2301 with remote clients and to send key agreement requests and
2302 negotiate the key agreement protocol with remote client. The
2303 key agreement is supported only to negotiate private message keys,
2304 it currently cannot be used to negotiate private keys for channels,
2305 as it is not convenient for that purpose.
2307 * Fixed a minor pending callback setting bug in the function
2308 silc_client_get_client_by_id_resolve, now the function works.
2309 Affected file lib/silcclient/idlist.c.
2311 * Added function silc_net_get_local_port to get local bound
2312 port by socket. Added to lib/silcutil/silcnet.[ch].
2314 * Added `sockets' and `sockets_count' fields to the SilcClient
2315 object. They hold the sockets of the listenning sockets in
2316 the client. Listenning sockets may be for example the key
2317 agreement server. Affected file lib/silcclient/client.[ch].
2318 Added functions the silc_client_add_socket and the
2319 silc_client_del_socket. They are exported to the application
2322 * Added ~./silc/clientkeys to support other client's public keys.
2324 * Renamed verify_server_key client operation to verify_public_key
2325 and added one argument to indicate the type of the connection
2326 (server, client etc.).
2328 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Added silc_server_connection_auth_request to handle the
2331 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2332 silcd/packet_receive.[ch].
2334 * Added silc_server_send_connection_auth_request into the
2335 silcd/packet_send.c to send the connection auth request packet.
2337 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2340 * Fixed the public key authentication in responder side in the
2341 server. The `auth_data' pointer includes the SilcPublicKey
2342 not the path to the public key. Affected file silcd/protocol.c.
2344 * Implemented the public key authentication in the initiator side
2345 in the server. Affected file silcd/protocol.c.
2347 * Removed the [RedirectClient] config section from the server
2348 configuration. Is not needed and I don't want to implement it.
2350 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Cleaned up the CMODE command in the server. It now works
2353 correctly and supports all the modes defined in the protocol.
2354 Affected file is silcd/command.c.
2356 * Added `hmac_name' field to the SilcChannelEntry in the server
2357 to hold the default HMAC of the channel. It can be set when
2358 creating the channel (with JOIN command). Affected files
2361 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2362 type to indicate the change of the current cipher and hmac
2363 on the channel. Client can safely ignore the <cipher> argument
2364 (if it chooses to do so) since the CHANNEL_KEY packet will
2365 force the channel key change anyway. The <hmac> argument is
2366 important since the client is responsible of setting the new
2367 HMAC and the hmac key into use.
2369 * Fixed the CMODE command in the client library as well.
2371 * Tested CMODE command in router environment successfully.
2373 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Show the version of the remote client (or server) when connecting
2376 to the server. It is logged to the log file. Affected file
2377 is silcd/protocol.c.
2379 * Fixed the KILLED notify handling in the client library. The
2380 client must be removed from all channels when receiving the
2383 Also, do not remove the client entry when giving the KILL
2384 command but when the KILLED notify is received.
2386 * Removed silc_idlist_find_client_by_nickname from the server.
2387 Not needed anymore. Affected files silcd/idlist.[ch].
2389 * Implemented the CHANNEL_CHANGE notify type handling to the
2390 server. Affected file silcd/server.c.
2394 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Added silc_server_send_notify_invite to send the INVITE
2397 notify between routers.
2399 * Implemented the INVITE command correctly to the server.
2401 * Implemented the INVITE notify type handling in the server.
2403 * Implemented the INVITE command to the client library and on the
2406 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Added function silc_server_get_client_resolve to find the
2409 client entry by ID from all ID lists and then resolve it
2410 (using WHOIS) if it cannot be found. Affected file is
2413 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Implemented the BAN command to the client library.
2417 * The JOIN command in the server now checks the invite list
2420 * Changed the silc_command_reply_payload_encode_va and the
2421 silc_command_payload_encode_va to support that if argument is
2422 NULL it ignores and checks the next argument. Affected file
2423 lib/silccore/silccommand.c.
2425 * Added silc_server_send_notify_ban to send the BAN notify
2426 type between routers.
2428 * Chaned the silc_notify_payload_encode to support that if
2429 argument is NULL it ignores and checks the next argument.
2430 Affected file lib/silccore/silcnotify.c.
2432 * Tested ban lists in router environment successfully.
2434 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Implemented BAN command to the server, in silcd/command.[ch].
2438 * Removed the BAN and INVITE_LIST modes from the CMODE command
2441 * Added function silc_string_match to regex match two strings.
2442 Affected files lib/silcutil/silcutil.[ch].
2444 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Redefined parts of the SilcChannelEntry in the server to support
2447 the new ban and invite lists.
2449 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Redefined the INVITE command. The same command can be used to
2452 invite individuals to the channel but also to manage the invite
2453 list of the channel (to add to and remove from the invite list).
2454 Updated the protocol specs.
2456 * Added new command SILC_COMMAND_BAN that can be used to manage
2457 the ban list of the channel. Updated the protocol specs.
2459 * Removed the channel modes: the SILC_CMODE_BAN and the
2460 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2461 in the CMODE command. The equivalent features are now available
2462 using INVITE and BAN commands. Updated the protocol specs.
2464 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2465 in the network about change in the current ban list. The notify
2466 type is not used by the client.
2468 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2469 support the invite lists.
2471 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Added new function silc_string_regexify that converts string
2474 including wildcard characters into regex string that can
2475 be used by the GNU regex library. Added into the file
2476 lib/silcutil/silcutil.[ch].
2478 Added silc_string_regex_combine to combine to regex strings
2479 into one so that they can be used as one regex string by
2480 the GNU regex library. Added into the file
2481 lib/silcutil/silcutil.[ch].
2483 Added silc_string_regex_match to match two strings. It returns
2484 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2486 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * Imported GNU regex to the soruce tree into lib/contrib.
2489 Fixed some compiler warning from the regex.c.
2491 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Fixed MOTD command in the server to work in router environment.
2495 * Fixed the MOTD command in the client library to support
2496 the server argument in the command.
2498 * Added `nickname_len' argument to the silc_idlist_add_client
2499 in the server, as the `nickname' argument may be binary data
2502 * Added silc_idlist_get_channels to return all channels from
2505 * Implemented LIST command to the server. Affected file is
2508 * Implemented the LIST command to the client library and on the
2511 * Added [<user count>] argument to the LIST command reply.
2512 With private channels the user count is not shown.
2514 * Updated TODO and README.
2516 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * The client entry's data.registered must be TRUE even with
2519 global client entry on global client list. The data.registered
2520 is used to check whether the client is anymore in the network,
2521 for example with WHOWAS command so it must be valid.
2523 * Fixed the WHOWAS command in the server. It now actually works
2524 in router environment. Added function into silcd/command_reply.c
2525 silc_server_command_reply_whowas_save.
2527 * Added silc_idlist_purge function to the silcd/idlist.c
2528 to periodically purge the ID Cache.
2530 * Fixed INFO command in the server. It works now in router
2531 environment. Added <server name> argument to the INFO command
2532 reply. Updated the protocol specs.
2534 * Fixed minor bug in silc_idcache_purge to not purge if the
2535 expire value is zero.
2537 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2538 they were buggy because of the WHOWAS information.
2540 * Fixed local command MSG to handle the async resolving of
2541 the remote client properly. It used to fail the first MSG.
2542 Affected file silc/local_command.c.
2544 * Added `data_len' field to SilcIDCache context.
2546 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Update TODO. Todo in commands in the server.
2550 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2553 used by routers as broadcast packet to inform other routers
2554 about the changed user mode.
2556 Implemented the notify handling in the server. Affected file is
2557 silcd/packet_receive.c. Added the function
2558 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2560 * Added new generic Channel Payload and deprecated the New Channel
2561 Payload. The New Channel Payload is now the generic Channel
2564 * Added new argument `mode' to the silc_server_send_new_channel
2565 as it is required in the Channel Payload now.
2567 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2568 and created a new and real SilChannelPayload to represent the
2569 new generic Channel Payload. Implemented the encode/decode
2570 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2572 * Added silc_server_get_client_channel_list to return the list
2573 of channels the client has joined for WHOIS command reply.
2574 Affected file silcd/server.[ch].
2576 * Implemented the channel list sending in the WHOIS command reply
2577 in server and in the client.
2579 Implemented the channel list displaying on the user interface
2580 as well. Affected file silc/client_ops.c.
2582 * Added silc_channel_payload_parse_list to parse list of Channel
2583 Payloads. It returns SilcDList list of SilcChannelPayloads.
2584 Client for example can use this function to parse the list of
2585 channels it receives in the WHOIS command reply. The caller
2586 must free the list by calling silc_channel_payload_list_free.
2587 Affected files lib/silccore/silcchannel.[ch].
2589 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Added one new argument <user mode> to the WHOIS command reply
2592 to return the mode of the user in SILC. Updated the protocol
2595 Implemented it to the server and client.
2597 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Fixed the mode printing on the user interface on joining.
2600 Affected file silc/client_ops.c.
2602 * Implemented the UMODE command and user modes in general to the
2603 client library and to the user interface.
2605 * Implemented the UMODE command to the server.
2607 * The server now sends UNKNOWN_COMMAND error status if client sends
2608 unknown command. Affected file silcd/command.c.
2610 * All server commands now handle the command identifier the right
2611 way when sending the command reply to the client. The client can
2612 use to identify the command replies with the identifier.
2614 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Added silc_server_get_client_route to resolve the route to
2617 the client indicated by the client ID. Affected file is
2620 * Added silc_server_relay_packet as general function to relay
2621 packet to arbitrary destination. This deprecates functions
2622 like _send_private_message_key, _relay_notify etc. Affected
2623 file is silcd/packet_send.[ch].
2625 Removed silc_server_send_key_agreement,
2626 silc_server_send_private_message_key and
2627 silc_server_packet_relay_notify functions from the file
2628 silcd/packet_send.[ch].
2632 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2633 server. Affected file silcd/packet_receive.[ch].
2635 * Implemented the KILL command to the client. Implemented the
2636 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2637 Affected files lib/silcclient/command[_reply].c and
2638 lib/silcclient/client_notify.c. Implemented the KILL notify
2639 printing in the user inteface.
2641 * Fixed a lot silc_parse_nick memory leaks from the client
2642 library in the file lib/silcclient/command.c.
2644 * Changed the silc_server_send_notify_on_channels's `sender'
2645 argument from SilcSocketConnection to SilcClientEntry to
2646 check the sender as entry and not as connection object and not
2647 to send to the client provided as argument. The affected file
2648 is silcd/packet_send.[ch].
2650 * The notify packets that are destined directly to the client used
2651 to not to be processed by the server. Now changed that and the
2652 server processes all notify packets. After relaying the packet
2653 to the client the notify packet is processed in the server.
2655 * The silc_server_free_client_data now checks whether there is
2656 pending outgoing traffic for the client and purges the data to
2657 the network before removing the client entry.
2659 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2662 an client is killed from the SILC Network. Updated the protocol
2665 Added new function silc_server_send_notify_killed to the
2666 silcd/packet_send.[ch].
2668 * Added function silc_server_packet_relay_notify to relay notify
2669 packets that are destined directly to a client. In this case
2670 the server does not process the notify packets but merely relays
2671 it to the client. Affected file silcd/packet_send.[ch].
2673 Added also silc_server_packet_process_relay_notify to check
2674 whereto relay the notify. Affected file is
2675 silcd/packet_receive.[ch].
2677 * Implemented the KILL command to the server.
2681 * Added the backup schema desgined last fall to the protocol
2682 specs for everyone to see. The specification is in the
2683 *-spec-xx.txt draft and the packet type definitions for the
2684 backup routers is in *-pp-xx.txt draft. Thusly, added also
2685 new packet type SILC_PACKET_CELL_ROUTERS.
2687 * A big security problem in the implementation discovered. The
2688 signoff of an client did not cause new channel key generation
2689 which it of course should've done. The channel keys must be
2690 always re-generated when client leaves (or signoffs) the channel.
2691 The silc_server_remove_from_channels funtion now handles
2692 the channel key re-generation.
2694 * Added `sender' argument to the silc_server_send_notify_on_channels
2695 to not to send the client provided as argument. Affected file
2696 silcd/packet_send.[ch].
2698 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Implemented OPER and SILCOPER commands into the server and
2703 * Added silc_auth_verify and silc_auth_verify_data to verify
2704 the authentication directly from the authentication payload.
2705 It supports verifying both passphrase and public key based
2706 authentication. Affected file lib/silccore/silcauth.[ch].
2708 * Added `hash' field to the SilcIDListData structure. It is the
2709 hash negotiated in the SKE protocol. Affected file is
2712 * Slight redesigning of the SilcAuthPayload handling routines.
2713 Do not send SilcPKCS but SilcPublicKey as argument.
2715 * Implemented the public key authentication support to the
2716 serverconfig. The public key is loaded from the provided path
2717 and saved as authentication data to void * pointer. Thus,
2718 changed the unsigned char *auth_data to void *auth_data;
2720 * Fixed SHUTDOWN command to send the reply before the server
2721 is shutdown. :) Affected file silcd/command.c.
2723 * Fixed fatal bug in CONNECT command. The hostname was invalid
2724 memory and server crashed. Affected file silcd/command.c.
2726 * Fixed fatal bug in CLOSE command. The server_entry became
2727 invalid but was referenced later in the command. Affected file
2730 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * Fixed fatal bug in failure packet handling. Server ignored
2733 the failure and thus crashed when it came.
2737 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2740 that the command may be executed only once in (about) 2 seconds.
2741 The old SILC_CF_LAG flag is same but allows command bursts up
2742 to five before limiting.
2744 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2745 server code. Various commands now includes the CF_LAG_STRICT
2746 flag to disallow any kind of miss-use of the command.
2748 * Fixed the silc_buffer_unformat to not to allocate any data
2749 if the length of the data is zero. It used to allocate the
2750 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2752 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Changed the format of AdminConnection configuration section
2755 in the server. Added username of the admin to the format.
2756 Affected files silcd/serverconfig.[ch].
2758 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2759 to return admin configuration data by host, username and/or
2762 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Implemented WHOWAS command to the server. Added the functions:
2766 silc_server_command_whowas_parse,
2767 silc_server_command_whowas_send_reply,
2768 silc_server_command_whowas_from_client and
2769 silc_server_command_whowas_from_server
2771 * Added <Client ID> argument to the WHOWAS command reply. Updated
2772 the protocol specs accordingly.
2774 * Implemented WHOWAS command and command_reply to the client
2777 Implemented the WHOWAS printing on the user interface.
2779 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Added new argument to the WHOWAS command reply, the real name.
2782 It is an optional argument. Updated the protocol specs.
2784 * Added SilcIDCacheDestructor callback that is registered when
2785 the SilcIDCache is allocated. The callback is called when
2786 an cache entry in the ID Cache expires, or is purged from the
2787 cache. Added into lib/silccore/idcache.[ch].
2789 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2790 to destruct the client entries when the cache entry expires.
2791 Other ID Cache's in server and in the client library ignores
2794 * If the ID Cache entry's `expire' field is zero then the entry
2795 never expires. Added boolean `expire' argument to the
2796 silc_idcache_add function in the lib/silccore/idcache.[ch].
2797 If it is TRUE the default expiry value is used.
2799 * Added silc_server_free_client_data_timeout that is registered
2800 when client disconnects. By default for 5 minutes we preserve
2801 the client entry for history - for WHOWAS command.
2803 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Added support to the server to enforce that commands are not
2806 executed more than once in 2 seconds. If server receives
2807 commands from client more frequently, timeout is registered
2808 to process the commands. Affected file silcd/command.c.
2809 Added new function silc_server_command_process_timeout.
2811 * Changed NICK_NOTIFY handling in client library to check that
2812 if the client's nickname was changed, so there is no need to
2813 resolve anything from the server.
2815 * Removed error printing from the WHOIS and IDENTIFY commands.
2816 If error occurs then it is ignored silently in the client library.
2817 The application, however, may map the received error to
2818 human readable error string. The application currently maps
2819 the NO_SUCH_NICKNAME error to string.
2821 * Made the command status message public to the application. Moved
2822 them from lib/silcclient/command_reply.c to
2823 lib/silcclient/command_reply.h. The application can map the
2824 received command status to the string with the
2825 silc_client_command_status_message function.
2827 * Added check to the server to check that client's ID is same
2828 as the Source ID in the packet the client sent. They must
2831 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Added dist-bzip hook to the Makefile.am to make bzip2
2834 compressed distributions.
2836 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Server now enforces the maximum length for the nickname and
2839 the channel as protocol specification dictates. 128 bytes for
2840 nickname and 256 bytes for channel name.
2842 * Moved the WHOIS printing to the application. The client libary
2843 does not print out the WHOIS information anymore, the application
2844 must do it. Renamed silc_client_command_reply_whois_print to
2845 the silc_client_command_reply_whois_save.
2847 The client's idle time is also sent to the application now, and
2848 the idle is shown on screen.
2850 * Added silc_client_command_reply_identify_save to save the
2851 received IDENTIFY entries.
2853 * Do not check for channel private keys in message sending and
2854 reception if the channel does not have the PRIVKEY mode set.
2855 Affected file lib/silclient/client_channel.c.
2857 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2860 just surfaced after chaning the JOIN procedure.
2862 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Added silc_client_get_clients_by_list to get client entries
2865 from Client ID list, that is returned for example by JOIN
2866 and USERS command replies. The application should use this
2867 function for example when JOIN command reply is received to
2868 resolve the clients already on the channel (library does not
2869 do that anymore as USERS command reply is not used in the JOIN
2870 procedure anymore). Affected files lib/silcclient/silcapi.h and
2871 lib/silcclient/idlist.c.
2873 * JOIN command reply and USERS command reply returns now SilcBuffer
2874 pointers instead of unsigned char pointers when returning
2875 the client list and mode list.
2877 * Added <Client ID> argument to the JOIN command reply, mainly
2878 for the server to identify for which client the command was
2879 originally sent. Updated protocol specs accordingly.
2881 * Added SilcDlist private_key pointer to the SilcChannelEntry
2882 in the client to support the channel private keys. Affected
2883 file is lib/silcclient/idlist.h.
2885 * Added SilcChannelPrivateKey argument to the function
2886 silc_client_send_channel_message so that application can choose
2887 to use specific private ke if it wants to. If it is not provided,
2888 the normal channel key is used, unless private keys are set.
2889 In this case the first (key that was added first) is used
2890 as the encryption key.
2892 * Implemented the support for channel private key handling.
2893 Implemented the following functions:
2895 silc_client_add_channel_private_key,
2896 silc_client_del_channel_private_keys,
2897 silc_client_del_channel_private_key,
2898 silc_client_list_channel_private_keys and
2899 silc_client_free_channel_private_keys
2901 Affected file lib/silcclient/client_channel.c.
2903 * Added the support for the private keys in the channel message
2904 sending and encryption and in the message reception and
2905 decryption. Affected funtions are
2906 silc_client_send_channel_message and silc_client_channel_message.
2908 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added SKE's key verify callback to the client library's
2911 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2913 * Removed the statement that server (or router) must send USERS
2914 command reply when joining to the channel so that the client
2915 knows who are on the channel. Instead, the client list and
2916 client's mode list is now sent in the JOIN command reply to the
2917 client who joined channel. This is better solution.
2919 * Added function silc_server_get_users_on_channel and function
2920 silc_server_save_users_on_channel to the silcd/server.[ch].
2922 * Removed function silc_server_command_send_users from the
2925 * Do not show topic on the client library anymore. The topic is
2926 sent in the command reply notify to the application and the
2927 application must show the topic now.
2929 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Added client searching by nickname hash into the IDENTIFY and
2932 WHOIS commands in the server as they were clearly missing from
2933 them. Affected file is silcd/command.c.
2935 * Fixed a bug in private message receiving in the client library.
2936 The remote ID was freed and it wasn't supposed, now it is
2939 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Minor fix to the channel payload; allocate the data area, as it
2942 needs to be of specific length.
2944 * If the key agreement port is zero then the operating
2945 system will define the bound port. Affected files are
2946 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2948 * Added new function silc_channel_payload_decrypt into the file
2949 lib/silccore/silcchannel.[ch].
2951 * Moved the channel message etc, check from silc_packet_decrypt
2952 to applications. The library calls now a generic
2953 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2954 when the packet is either normal or special. This was done to
2955 allow more wide range of checking that was not allowed when
2956 the code was in library. Now applications can do virtually any
2957 checks to the packet and return to the library the decision how
2958 the packet should be processed. Affected files are
2959 lib/silccore/silcpacket.[ch].
2961 Added silc_server_packet_decrypt_check to the server and
2962 silc_client_packet_decrypt_check to the client library.
2964 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2965 to send with specified source and destination information.
2967 * Channel message delivery between routers was broken after the
2968 channel key distribution was fixed earlier. The channel key
2969 was used be to distributed to other routers as well which is not
2970 allowed by the protocol. Now this is fixed and channel keys
2971 really are cell specific and the channel message delivery between
2972 routers comply with the protocol specification.
2974 * Fixed various commands in server to check also the global list
2975 for the channel entry and not just the local list. The affected
2976 file silcd/command.c.
2978 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Added assert()s to buffer formatting and unformatting routines
2981 to assert (if --enable-debug) when error occurs. Affected
2982 file: lib/silcutil/silcbuffmt.c.
2984 * Changed to auto-reconnect to check whether the remote host is
2985 router and register the re-connect timeout if it is. It used
2986 to check that whether we are normal server, but router must do
2987 auto-reconnect with another router as well. Affected file
2990 * Removed the [<key len>] option from CMODE command as the cipher
2991 name decides the key length, nowadays. See the defined ciphers
2992 from the protocol specification.
2994 * Added [<hmac>] option to the CMODE command to define the HMAC
2995 for the channel. Added SILC_CMODE_HMAC channel mode.
2997 * Added [<hmac>] option for the JOIN command so that user can
2998 select which HMAC is used to compute the MACs of the channel
3001 * Added Hmac field to the Channel Message Payload. The integrity
3002 of plaintext channel messages are now protected by computing
3003 MAC of the message and attaching the MAC to the payload. The
3004 MAC is encrypted. Now, it is clear that this causes some
3005 overhead to the size of the packet but rationale for this is that
3006 now the receiver can verify whether the channel message decrypted
3007 correctly and also when private keys are set for the channel the
3008 receiver can decrypt the packet with several keys and check from
3009 the MAC which key decrypted the message correctly.
3011 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3012 lib/silccrypt/silccipher.[ch].
3014 * Added silc_hash_len to return the digest length into the
3015 lib/silcrypt/silchash.[ch].
3017 * Rewrote parts of Silc Channel Payload interface in the
3018 lib/silccore/silcchannel.[ch]. The encode function now also
3019 encrypts the packet and parse function decrypts it.
3021 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Fixed a minor formatting bug in the SKE's key material processing.
3024 It actually might have processed the keys wrong way resulting
3027 * Redefined the mandatory HMAC algorithms and added new algorithms.
3028 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3029 and hmac-md5 truncated to 96 bits. The mandatory is now
3030 hmac-sha1-96. Rest are optional (including the one that used
3031 to be mandatory). Rationale for this is that the truncated HMAC
3032 length is sufficient from security point of view and can actually
3033 make the attack against the HMAC harder. Also, the truncated
3034 HMAC causes less overhead to the packets. See the RFC2104 for
3037 * Added new [hmac] configuration section. The SKE used to use
3038 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3039 is of course wrong. The official names that must be proposed in
3040 the SKE are the ones defined in the protocol specification
3041 (hmac-sha1-96 for example). The user can configure any hmac
3042 using any hash function configured in the [hash] section. At
3043 least, the mandatory must be configured.
3045 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3047 * Added HMAC list to the SKE proposal list. It has now both
3048 hash algorithm list and HMAC list. This makes the protocol
3049 incompatible with previous versions. The SKE now seems to work
3050 the way it is supposed to work, for the first time actually.
3052 * Defined plain Hash algorithms to the protocol specification.
3055 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Implemented support for key agreement packets into the server.
3058 Added functions silc_server_key_agreement and
3059 silc_server_send_key_agreement. Other than these functions,
3060 server has nothing to do with this packet.
3062 * Added support for private message key packets into the server.
3063 Added functions silc_server_private_message_key and
3064 silc_server_send_private_message_key.
3068 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3069 called in the protocol's final callback instead in the END
3070 protocol state. This makes a little more sense and in the same
3071 time in client we can use the same protocol routines for normal
3072 key exchange and to key agreement packet handling as well.
3074 * Added to both client's and server's KE protocol context the
3075 SilcSKEKeyMaterial pointer to save the key material. We will
3076 bring the key material to the protocol's final callback by doing
3077 this. The final callback must free the key material.
3079 * Added SKE's packet_send callback into client's KE protocol
3080 context so that the caller can choose what packet sending function
3081 is used. This way we can use different packet sending when
3082 doing normal SKE when doing key agreement packet handling (in
3083 the key agreement packet handling we do not want to encrypt
3086 * Implemented the responder side of the key agreement routines
3087 in the client. The client can now bind to specified port and
3088 accept incoming key negotiation. The key material is passed
3089 to the application after the protocol is over.
3091 * Implemented the processing of incoming Key Agreement packet
3092 in the client. Added function silc_client_key_agreement to
3095 * Implemented the intiator side of the key agreement routines
3096 in the client. The client can now initiate key agreement with
3097 another remote client. The key material is passed to the
3098 application after the protocol is over.
3100 * Created client_keyagr.c to include all the key agreement
3103 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3104 SILC_TASK_CALLBACK except that it is not static.
3106 * Created client_notify.c and moved the Notify packet handling
3107 from the client.[ch] into that file.
3109 * Created client_prvmsg.c and moved all private message and
3110 private message key routines from the client.[ch] into that file.
3112 * Create client_channel.c and moved all channel message and
3113 channel private key routines from the client.[ch] into that file.
3115 * Changed silc_client_get_client_by_id_resolve to resolve with
3116 WHOIS command instead of IDENTIFY command, in the file
3117 lib/silclient/idlist.c.
3119 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Implemented the SKE's responder side to the Client library.
3123 * When FAILURE is received to the protocol do not trust it
3124 blindly. Register a timeout to wait whether the remote closes
3125 the connection as it should do it, only after that process the
3126 actual failure. This was changed to both client and server.
3128 * Added client_internal.h to include some of the structures
3129 there instead of client.h in lib/silcclient/.
3131 * Added function silc_task_unregister_by_callback to unregister
3132 timeouts by the callback function.
3134 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Some "Incomplete WHOIS info" errors has been appearing on the
3137 log files. Took away the entry->userinfo check from WHOIS
3138 reply sending. The entry->userinfo is now " " if client did not
3139 provide one. I thought this was fixed earlier but something
3140 is wrong still. Let's see if the error still appears.
3142 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Fixed a minor bug in the login when the channel key is
3145 re-generated in the server. It used to generate the key in
3146 wrong order and thus caused problems in the channel traffic.
3148 * Fixed a minor bug in channel key distsribution after
3149 KICK command. The key was not sent to the router even though
3152 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Added silc_ske_process_key_material_data as generic routine
3155 to process any key material as the SILC protocol dictates. The
3156 function is used by the actual SKE library but can be used by
3157 applications as well. This relates to the private message keys
3158 and the channel private keys since they must be processed the
3159 same way the normal SILC session keys. The protocol dictates
3160 this. Affected files: lib/silcske/silcske.[ch].
3162 Added also silc_ske_free_key_material to free the
3163 SilcSKEKeyMaterial structure.
3165 * Defined silc_cipher_set_key function to set the key for
3166 cipher without using the object's method function. The affected
3167 files: lib/silccrypt/silccipher.[ch].
3169 * Implemented silc silc_client_add_private_message_key,
3170 silc_client_add_private_message_key_ske,
3171 silc_client_del_private_message_key,
3172 silc_client_list_private_message_keys and
3173 silc_client_free_private_message_keys functions in the
3176 Added functions silc_client_send_private_message_key to send
3177 the Private Message Key payload and silc_client_private_message_key
3178 to handle incoming Private Message Key payload.
3180 * Added Cipher field to the Private Message Key payload to set
3181 the cipher to be used. If ignored, the default cipher defined
3182 in the SILC protocol (aes-256-cbc) is used.
3184 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Removed lib/silcclient/ops.h file.
3188 Redefined parts of the SILC Client Library API. Created new
3189 file silcapi.h that deprecates the ops.h file and defines the
3190 published Client Library API. Defined also private message key
3191 API and channel private key API into the file.
3193 This is the file that the application must include from the
3194 SILC Client Library. Other files need not be included by
3195 the application anymore.
3197 * Added new key_agreement client operation callback and also
3198 defined the Key Agreement library API for the application.
3200 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3203 is used by clients to request key negotiation between another
3204 client in the SILC network. If the negotiation is started it
3205 is performed using the SKE protocol. The result of the
3206 negotiation, the secret key material, can be used for example
3207 as private message key.
3209 Implemented the Key Agreement payload into the files
3210 lib/silccore/silauth.[ch].
3212 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Redefined ciphers for the SILC protocol. Added some new ciphers
3215 and defined the key lengths for the algorithms. Changed the
3216 code accordingly. The default key length is now 256 bits.
3218 * Fixed SKE key distribution function silc_ske_process_key_material
3219 when the key length is more than 128 bits. The default key
3220 length in SILC is now 256 bits.
3222 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3223 to indicate unsupported algorithm.
3225 * Renamed rijndael.c to aes.c and all functions as well.
3227 * Fixed a long standing channel key setting bug in client library.
3228 Weird that it has never surfaced before.
3230 * Fixed bug in channel deletion. If the entire channel is removed
3231 then it must also delete the references of the channel entry
3232 from the client's channel list as the client's channel entry and
3233 the channel's client entry share same memory.
3235 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Implemented CONNECT and SHUTDOWN commands in the client.
3239 * Implemented CLOSE command to the client.
3241 * Added the function silc_idlist_find_server_by_name into the
3242 files silcd/idlist.[ch].
3244 Added the function silc_idlist_find_server_by_conn into the
3245 files silcd/idlist.[ch].
3247 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * DIE command was renamed to SHUTDOWN. Updated the both code
3252 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3253 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3255 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3258 * Added function silc_server_create_connection function to create
3259 connection to remote router. My server implementation actually
3260 does not allow router to connect to normal server (it expects
3261 that normal server always initiates the connection to the router)
3262 so the CONNECT command is only good for connecting to another
3265 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3268 or some other client was kicked from the channel.
3270 Implemented the handling of the notify type to both client
3273 Implemented silc_server_send_notify_kicked to send the KICKED
3274 notify. It is used to send it to the server's primary router.
3276 * Implemented the KICK command into server and client.
3278 * Added `query' argument to the silc_idlist_get_client function
3279 to indicate whether to query the client from server or not if
3282 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3283 to indicate that the client is not channel founder.
3287 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Removed the rng context from SilcPacketContext structure and
3290 changed that the packet routine uses the Global RNG API.
3292 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Added support for quit message that client can "leave" on the
3295 channel when it quits the SILC. It is ditributed inside the
3296 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3298 Added silc_server_free_client_data that will take the
3299 signoff message as argument.
3301 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3303 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Updated parts of the protocol specification to keep it up
3308 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3311 payloads in one packet.
3313 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3314 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3315 use now the new List flag.
3317 * Also deprecated the following packet types: REPLACE_ID,
3318 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3320 * Added list support for Notify packet in server.
3322 * Added silc_server_send_notify_channel_change to send the
3323 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3324 the silc_server_send_replace_id.
3326 * Added silc_server_send_notify_nick_change to send the
3327 NICK_CHANGE notify type. Deprecates the function
3328 silc_server_send_replace_id.
3330 * Added silc_server_send_notify_join to send the JOIN notify type.
3331 Deprecates the function silc_server_send_new_channel_user.
3333 * Added silc_server_send_notify_leave to send LEAVE notify type.
3334 Deprecates the function silc_server_send_remove_channel_user.
3336 * Added silc_server_send_notify_cmode and
3337 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3338 types. Deprecates the silc_server_send_set_mode function.
3340 * Added SERVER_SIGNOFF notify type to indicate that server has
3341 quit. This means that all clients on the channel from that
3342 server will drop. This can be also used when netsplit happens.
3344 Deprecated REMOVE_ID packet type since it is not needed anymore
3347 Added silc_server_send_notify_server_signoff to send the
3348 SERVER_SIGNOFF notify type. Deprecates the function
3349 silc_server_send_remove_id.
3351 Added also silc_server_send_notify_signoff to send the
3352 SIGNOFF notify type.
3354 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3355 SILC protocol from this day on. Changed the protocol
3356 specification as well.
3358 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3359 notify type. It is used between routers to notify about
3360 topic changes on a channel.
3362 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3365 * Partly updated the protocol specification to comply with the
3366 changes now made. It is still though a bit outdated.
3368 * The JOIN notify type now takes one extra argument <Channel ID>.
3369 The packet used to be destined to the channel but now the
3370 JOIN type may be sent as list thus it is impossible to
3371 destine it to any specific channel. By adding this argument
3372 it is again possible.
3374 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Added CREDITS file. The CHANGES and CREDITS file will appear
3377 in the distribution as well.
3379 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3382 types in the server's silcd/packet_receive.c.
3384 * Implemented CMODE and CUMODE to work in router environment.
3386 * Fixed minor encoding and decoding buglet from the
3387 lib/silccore/silcmode.c.
3389 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3392 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3394 * Changed all SilcConfigServer* and silc_config_server* to
3395 SilcServerConfig* and silc_server_config*, respectively.
3398 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Associated the ID (client or server ID) to the Authentication
3401 Payload to avoid any possibility of forging. Updated the
3402 protocol specification and the code accordingly.
3404 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * The RSA key length is now save to the RsaKey context in the
3407 key generation process in lib/silccrypt/rsa.c. The key length
3408 is now used to figure out the maximum size of the block allowed
3409 to be encrypted/signed.
3411 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3412 is equivalent to the silc_mp_mp2bin but does not allocate any
3415 * Changed silc_mp_mp2bin API to take length argument. If it is
3416 non-zero then the buffer is allocated that large. If zero, then
3417 the size is approximated using silc_mp_sizeinbase, which however
3420 * Created Global RNG API which is global RNG that application can
3421 initialize. After initializing, any routine anywhere in the
3422 code (including library) can use RNG without allocating a new
3423 RNG object. This was done to allow this sort of use of the
3424 RNG in code that has no chance to allocate RNG object. All
3425 applications currently allocate this and many routines in the
3426 library use this. Affected file lib/silccrypt/silcrng.[ch].
3428 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3429 it to use the Global RNG API.
3431 * Defined Authentication Payload into protocol specification that
3432 is used during SILC session to authenticate entities. It is
3433 used for example by client to authenticate itself to the server
3434 to obtain server operator privileges.
3436 Implemented this payload into the lib/silccore/silcauth.[ch].
3437 Implemented also routines for public key based authentication
3438 as the new protocol specification dictates.
3440 Moved definitions of different authentication methods from
3441 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3443 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3444 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3445 silc_pkcs_verify_with_hash functions into the file
3446 lib/silccrypt/silcpkcs.[ch].
3448 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * The client entry's userinfo pointer must be always valid.
3451 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3452 will fail since it requires the userinfo. Now, the userinfo
3453 is allocated as "" if actual userinfo does not exist. Actually,
3454 it must exist and it is totally Ok to drop client connections
3455 that does not announce the userinfo. However, we will make
3456 this workaround for now.
3458 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3459 to return the remote port by socket.
3461 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3464 SILC_SERVER_PENDING_EXEC and added an new macro
3465 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3466 data or when error occurs while processing the pending command.
3468 Added new argument `destructor' into silc_server_command_pending
3469 and to the SilcServerCommandPending object. This destructor is
3470 now called after calling the pending callback or if error occurs
3471 immediately. If error occurs the actual pending callback won't
3472 be called at all - only the destructor. The destructor may be
3473 NULL if destructor is not needed.
3475 All this applies for client library code as well. Similar
3476 changes were made there as well for the pending commands.
3478 In the client, the application must now allocate the
3479 SilcClientCommandContext with the silc_client_command_alloc
3482 * Added reference counter to the SilcServerCommandContext. Added
3483 function silc_server_command_alloc and silc_server_command_dup
3486 Same type of functions added to the client library for the same
3489 * Removed the cmd_ident from IDListData away since it is now
3490 global for all connections. It is the command identifier used
3491 in command sending and with pending commands. The affected file
3494 * Added reference counter to the SilcSocketConnection objecet to
3495 indicate the usage count of the object. The object won't be
3496 freed untill the reference counter hits zero. Currently only
3497 server uses this, and client ignores it. The client must be
3498 set to use this too later. The affected files are
3499 lib/silccore/silcsockconn.[ch]. Added also the function
3500 silc_socket_dup to increase the reference counter.
3502 This was mainly added because it is possible that the socket
3503 is removed underneath of pending command or other async
3504 operation. Now it won't be free'd and proper DISCONNECTING
3505 flags, etc. can be set to avoid sending data to connection that
3506 is not valid anymore.
3508 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3509 the connection. After that it sets SILC_SET_DISCONNECTED.
3510 It is, however, possible that the socket data is not still freed.
3511 The silc_server_packet_process now checks that data is not
3512 read or written to connection that is DISCONNECTED. The socket
3513 get's freed when the reference counter hits zero.
3515 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Changed the client operation API: channel_message operation's
3518 `sender' is now the client entry of the sender, not the nickname
3519 and the `channel' is the channel entry, not the channel name.
3521 In the private_message operation the `sender' is now also the
3522 client entry of the sender not the nickname.
3524 Affected file is lib/silcclient/ops.h and all applications
3525 using the client operations.
3527 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Moved the calling of ops->connect() from connect_to_server_final
3530 into receive_new_id functin since that is the point when the
3531 client is actually allowed to send traffic to network. The
3532 affected file is lib/silcclient/client.c.
3534 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3537 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3538 (if needs broadcasting) instead of broadcasting the packets one
3539 by one which would make a burst in the network traffic.
3541 * Added `broadcast' argument to the functions in silcd/server.[ch]
3542 silc_server_create_new_channel[_with_id] to indicate whether
3543 to send New Channel packet to primary router.
3545 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added new function into the silcd/server.[ch] files:
3548 silc_server_create_new_channel_with_id to create new channel with
3549 already existing Channel ID.
3551 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3552 lib/silccore/silcpacket.h. This packet is used t send list of
3553 Set Mode payloads inside one packet. Server uses this to set
3554 the modes for the channels and clients on those channels, that it
3555 announced to the router when it connected to it. The protocol
3556 specification has been updated accordingly.
3558 * The silc_server_new_channel did not handle the packet coming
3559 from normal server as it normally does not send that. However,
3560 when it announces its channels it does send it. Implemented
3561 the support for that.
3563 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3564 into the file lib/silccore/id.h.
3566 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Fixed memory leaks in the functions silc_idlist_del_client,
3569 silc_idlist_del_channel and silc_idlist_del_server in the file
3570 silcd/idlist.c. All of those leaked like a sieve.
3572 * Fixed some small memory leaks in the client's function
3573 silc_client_notify_by_server.
3575 * Added functions into silcd/server.c: silc_server_announce_clients,
3576 silc_server_announce_channels and silc_server_announce_server.
3577 These functions are used by normal and router server to announce
3578 to its primary router about clients, channels and servers (when
3579 router) that we own. This is done after we've connected to the
3582 These functions effectively implements the following packet types:
3583 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3584 and SILC_PACKET_NEW_ID_LIST.
3586 * Added new functions into the silcd/packet_receive.[ch]:
3587 silc_server_new_id_list, silc_server_new_channel_list and
3588 silc_server_new_channel_user_list to handle the incoming
3589 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3591 * Added support of changing Channel ID in the function
3592 silc_server_replace_id. If the server that announces a channel
3593 to the router already exists in the router (with same name but
3594 with different Channel ID), router is responsible to send
3595 Replace ID packet to the server and force the server to change
3596 the Channel ID to the one router has.
3598 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3599 client that the Channel ID has been changed by the router. The
3600 normal server sends this to the client. Client must start using
3601 the new Channel ID as the channel's ID.
3603 Implemented handling of this new type into lib/silcclient/client.c
3604 into the function silc_client_notify_by_server.
3606 * Added new function silc_idlist_replace_channel_id into the files
3607 silcd/idlist.[ch] to replace the Channel ID.
3609 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Call silc_server_command_identify_check always when processing
3612 the IDENTIFY command in silcd/command.c
3614 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3617 send keepalive packets. The packet can be sent by clients,
3618 servers and routers.
3620 Added function silc_socket_set_heartbeat into the file
3621 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3622 If not set, the heartbeat is not performed. The actual
3623 heartbeat is implemented in the low level socket connection
3624 library. However, application is responsible of actually
3627 Added silc_server_send_heartbeat to send the actual heartbeat
3628 packet into silcd/packet_send.[ch]. Server now performs
3629 keepalive with all connections.
3631 * Added silc_task_get_first function into lib/silcutil/silctask.c
3632 to return the timeout task with shortest timeout. There was a bug
3633 in task unregistration that caused problems. TODO has been
3634 updated to include that task system must be rewritten.
3636 * The client library will now resolve the client information when
3637 receiving JOIN notify from server for client that we know but
3638 have incomplete information.
3640 * Rewrote parts of silc_server_remove_from_channels and
3641 silc_server_remove_from_one_channel as they did not remove the
3642 channel in some circumstances even though they should've.
3644 * Encryption problem encountered in server:
3646 The LEAVE command used to send the Channel Key packet to the
3647 router immediately after generating it. However, the code
3648 had earlier sent Remove Channel user packet but not immediately,
3649 ie. it was put to queue. The order of packets in the router
3650 was that Channel Key packet was first and Remove Channel User
3651 packet was second, even though they were encrypted in the
3652 reverse order. For this reason, MAC check failed. Now, this
3653 is fixed by not sending the Channel Key packet immediately but
3654 putting it to queue. However, this is more fundamental problem:
3655 packets that are in queue should actually not be encrypted
3656 because packets that are sent immediately gets encrypted
3657 actually with wrong IV (and thus MAC check fails). So, packets
3658 that are in queue should be encrypted when they are sent to
3659 the wire and not when they put to the queue.
3661 However, the problem is that the current system has not been
3662 designed to work that way. Instead, the packet is encrypted
3663 as soon as possible and left to the queue. The queue is then
3664 just purged into wire. There won't be any fixes for this
3665 any time soon. So, the current semantic for packet sending
3668 o If you send packet to remote host and do not force the send
3669 (the packet will be in queue) then all subsequent packets to the
3670 same remote host must also be put to the queue. Only after the
3671 queue has been purged is it safe again to force the packet
3674 o If you send all packets immediately then it safe to send
3675 any of subsequent packets through the queue, however, after
3676 the first packet is put to queue then any subsequent packets
3677 must also be put to the queue.
3679 Follow these rules and everything works fine.
3681 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Added new function silc_server_remove_clients_by_server to
3684 remove all client entries from ID list when the server connection
3685 is lost. In this case it is also important to invalidate all
3686 client entires as they hold the invalid server entry. This
3687 fixes fatal bug when server has lost connection and will reconnect
3690 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Made some sanity checks to silc_server_daemonise like to check
3693 whether the requested user and group actually exists.
3695 * Added sanity check to SKE's silc_ske_responder_finish to check
3696 that the public and private key actually is valid.
3698 * Invalidate the client's nickname when receiving Replace ID
3699 packet and the Client ID is being replaced. This means that the
3700 server will query the nickname if someone needs it (client)
3703 * Sort the ID Cache in client library when the ID Cache data
3704 has changed (needs sorting).
3706 * Do not allow for SILC client to create several connections to
3707 several servers. The client does not support windows right now
3708 and generating multiple connections causes weird behaviour.
3710 Irssi-silc client does support windows and can handle several
3711 connections without problems, see: www.irssi.org and SILC plugin.
3713 * Fixed some places where client was added to the IDList. The
3714 rule of thumb is following (in order to get everything right):
3715 If the client is directly connected local client then the
3716 `connection' argument must be set and `router' argument must be
3717 NULL to silc_idlist_add_client function. If the client is not
3718 directly connected client then the `router' argument must
3719 bet set and the `connection' argument must be NULL to the
3720 silc_idlist_add_client function.
3722 * The funtion silc_server_packet_send_local_channel actually did
3723 not check whether the client was locally connected or not. It
3724 does that now. Fixed a bug related to LEAVE command.
3726 * Fixed Remove Channel User payload parsing bug in server's
3727 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3729 * The server's silc_server_save_channel_key now checks also the
3730 global ID list for the channel as it might not be in the local
3731 list. Fixed a bug related to LEAVE command.
3733 * Is this the end of the [<unknown>] buglet that has been lurking
3734 around for a long time? A little for loop fix in server's
3735 silc_server_command_whois_parse that is used by both IDENTIFY
3736 and WHOIS command. At least, this was a clear bug and a cause
3737 of one type of [<unknown>] buglet.
3739 * WHOIS and IDENTIFY commands call the function
3740 silc_server_command_[whois/identify]_check function even if
3741 we are not router server.
3743 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Added --with-gmp configuration option. If set the GMP
3746 is always compiled in the SILC source tree. If not set then
3747 it is checked whether the system has the GMP3 installed. If
3748 it has then the GMP won't be compiled (the system's headers
3749 and library is used), if it doesn't have it then the GMP is
3750 compiled in the SILC source tree.
3752 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Changed RSA private exponent generation to what PKCS #1
3755 suggests. We try to find the smallest possible d by doing
3756 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3757 not security fix but optimization.
3759 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Added new config entry [Identity] to fork the server and run
3762 it as specific user and group. A patch from Bostik.
3764 * Imported Dotconf configuration library into lib/dotconf.
3765 This will be used to create the SILC configuration files later.
3766 It will appear in the distsribution after this commit.
3768 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * A big code auditing weekend happening. Auditing code for
3771 obvious mistakes, bugs and errors. Also, removing any code
3774 Removed files for being obsolete:
3776 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3777 inline in the file lib/silcutil/silcbuffer.h)
3779 o lib/silcutil/silcbufutil.c (the header has inline versions)
3781 Changed code to fix possible error conditions:
3783 o The buffer formatting routines now check that the destination
3784 buffer really has enough space to add the data. This applies for
3785 both buffer formatting and unformatting
3786 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3787 unformatting was changed to accomodate following rules:
3788 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3789 sent to the function while XXX_*STRING will not allocate or copy
3790 the data into the buffer. Instead it sets the pointer from the
3791 buffer into the pointer sent as argument (XXX_*STRING used to
3792 require that the pointer must be allocated already). This change
3793 makes this whole thing a bit more consistent and more optimized
3794 (note that the data returned in the unformatting with XXX_*STRING
3795 must not be freed now). The routines return now -1 on error.
3797 o Tried to find all code that use buffer_format and buffer_unformat
3798 and added return value checking to prevent formatting and
3799 especially unformatting errors and possible subsequent fatal
3802 o Changed ske->x and ske->KEY to mallocated pointers in
3803 lib/silcske/silcske.h. Fixed possible data and memory leak.
3805 o Added return value checking to all *_parse* functions. Fixed
3806 many memory leaks as well.
3808 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3809 so that buffer overflows would not happen. All code now also
3810 checks the return value as it can fail.
3812 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Added reconnection support to server if the normal server looses
3815 its connection to the router (for example if router is rebooted).
3816 The server performs normal reconnection strategy implemented
3817 to the server. Affected file silcd/server.c.
3819 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added new packet type SILC_PACKET_SET_MODE that is used to
3822 distribute the information about changed modes (for clients,
3823 channels and clients channel modes) to all routers in the
3824 network. Updated the protocol specification accordingly.
3826 Added functions into silcd/packet_send.c and
3827 silcd/packet_receive.c: silc_server_send_set_mode,
3828 silc_server_set_mode.
3830 Added new files silcmode.[ch] into lib/silccore that implements
3831 the encoding and decoding of Set Mode Payload. Added new type
3832 SilcSetModePayload. Moved the definitions of different modes
3833 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3835 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Oops, a little mistake in server's connection authentication
3838 protocol. The protocol is not ended with FAILURE but with
3839 SUCCESS if the authentication is Ok. :) Affected file is
3842 * Implemented NICK_CHANGE notify handling in server in the file
3843 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3844 the local clients on the channel. After the changing nickname
3845 in router environment snhould work and the [<unknown>] nickname
3846 should appear no more.
3848 The silc_server_replace_id function that receives the Replace ID
3849 payload now sends the NICK_CHANGE notify type also in the file
3850 silcd/packet_receive.c
3852 * Changed WHOIS and IDENTIFY command to support the maximum amount
3853 of arguments defined in protocol specs (3328 arguments). This
3854 fixed a bug that caused problems when there were more than three
3857 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Added extra parameter, command identifier, to the
3860 silc_client_send_command so that explicit command identifier
3863 Changed that ID list routines uses specific command identifier
3864 when sending WHOIS/IDENTIFY requests to the server so that they
3865 can be identified when the reply comes back.
3867 Affected files lib/silcclient/command.[ch],
3868 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3870 * Added `sender' argument to silc_server_packet_send_to_channel
3871 to indicaet the sender who originally sent the packet to us
3872 that we are now re-sending. Ignored if NULL. Affected file
3873 silcd/packet_send.[ch].
3875 * Added some server statistics support in silcd/server_internal.h
3876 SilcServerStatistics structure and around the server code. Also
3877 send some nice statistics information when client is connecting
3880 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Fixed channel ID decoding in server's JOIN command reply in
3883 silcd/command_reply.c
3885 * Fixed braodcasting of replace ID payload to not to send it if
3886 we are standalone server in silcd/packet_receive.c.
3888 * Fixed all channel message sending routines to not to send
3889 packets to clients that has router set, since they are routed
3890 separately in the same function earlier. Affects file
3891 silcd/packet_send.c and all channel packet sending functions.
3893 * In USERS reply, res_argv[i] are not allocated, the table
3894 is allocated. Thus changed that free the table, not its
3897 * In server's whois_check and identify_check if the client is
3898 locally connected do not send any WHOIS commands - they are not
3901 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Fixed some minor bugs in client when sending WHOIS command. The
3904 arguments was in wrong order.
3906 * Removed statis function add_to_channel from server in
3907 silcd/command.c that was previously used with the joining but
3910 * Tested USERS command in router environment successfully with two
3911 routers, two servers and two clients.
3913 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Reorganized the USERS command and command reply in client library
3916 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3917 When the command is given by user we register a pending command
3918 callback that will reprocess the command after the reply has been
3919 received from the server. When reprocessing the packet we then
3920 display the information. Thus, the USERS information is displayed
3921 now in the command callback instead of in the command reply
3922 callback. The processing of the command is same as previously
3923 when server has sent the command reply in the JOINing process.
3925 * Added to USERS command in silcd/command_reply.c to join the client,
3926 we didn't use to know about, to the channel after we've created
3927 a client entry for it. Also, for clienet we did know already still
3928 check whether it is on the channel or not and add it if not.
3930 * Removed silc_server_command_join_notify as the function and its
3933 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Changed the client's pending command handling to the same as the
3936 server's pending command handling. It is also now possible to
3937 execute command reply functions from other command reply
3938 function as the function callbacks for commands and command
3939 replies are one and same. The pending commands are not static
3940 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3941 in client connection context. Thus, pending commands are server
3942 connection specific as it is convenient.
3944 Changed the function silc_client_command_pending and
3945 silc_client_command_pending_del and added new function
3946 silc_client_command_pending_check. Removed the
3947 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3950 * Added cmd_ident, current command identifier, to the client
3951 connection context in lib/silcclient/client.h to keep track on
3952 command identifiers used in command sending. Client's command reply
3953 function handling now supports the mandatory command identifiers.
3955 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3956 funtions in client to fully support pending command callbacks.
3958 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3959 as one of the arguments to the application in the command reply
3962 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3963 before first releasing SILC but came back. Now it is removed again
3964 and should come back nomore. The FORWARDED flag was used only
3965 by the JOINing procedure by forwarding the command packet to router.
3966 Now, the JOINing procedure has been changed to more generic (due
3967 to various router environment issues) and FORWARDED is not needed
3968 anymore for anything. The protocol specification is yet to be
3971 Now, removed silc_server_packet_forward from server and the flag
3972 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3974 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Renamed NAMES command to USERS command. The NAMES was named that
3977 due to historical reasons. Now it is renamed. Also, rewrote
3978 parts of the USERS command. The nickname list is not sent anymore
3979 by the server. Only Client ID and mode lists are sent in the USERS
3980 command. Changed this also to the protocol specification.
3982 The client now resolves the names and stuff after it receives
3983 the USERS list from the server when joining to the channel.
3985 * WHOIS and IDENTIFY commands has been changed to support multiple
3986 Client ID's per command. One can now search for multiple users
3987 in the network by sending only one WHOIS or IDENTIFY command.
3988 Changed the code and the protocol specifications.
3990 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3991 uses silc_server_command_whois_parse to parse the request. */
3993 * If normal server, do not parse the WHOIS and IDENTIFY requests
3994 before sending it to the router. Saves some time.
3996 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Fixed JOIN command on client library. Wrong number of arguments
3999 used to crash the client.
4001 * Added silc_server_channel_has_global function to check whether
4002 channel has global users or not.
4004 * Added silc_server_channel_has_local function to check whether channel
4005 has locally connected clients on the channel.
4007 * The silc_server_remove_from_one_channel now checks whether the
4008 channel has global users or not after given client was removed from
4009 the channel. It also checks whether the channel has local clients
4010 on the channel anymore. If it does not have then the channel entry
4011 is removed as it is not needed anymore.
4013 * The silc_server_notify now checks on JOIN notify whether the joining
4014 client is one of locally connected or global. If it is global then
4015 the channel has now global users on the channel and that is marked
4016 to the channel entry. Also, it now saves the global client to
4017 global list who is joining and JOINs it to the channel. This is
4018 for normal server, that is.
4020 Changed silc_server_send_notify_on_channel,
4021 silc_server_packet_relay_to_channel and
4022 silc_server_packet_send_to_channel check if we are normal server
4023 and client has router set (ie. global client) do not send the
4024 message to that client, as it is already routed to our router.
4026 * Implemented LEAVE notify type handling in silc_server_notify
4029 * Tested LEAVE command in router environment successfully. Tested
4030 with two routers, two servers and two clients.
4034 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4036 * Implemented SIGNOFF notify type handling in silc_server_notify
4039 * silc_server_remove_id now removes the client entry from all channels
4040 it has joined and thusly sends SIGNOFF notify type.
4042 * Rewrote the NAMES list generation in server by removing two excess
4043 loops. The lists are created now inside one loop.
4045 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * silc_server_remove_channel_user checks now also global list
4048 for channel and client.
4050 * silc_server_new_channel_user checks now both local and global
4051 list for channel and client. Fixed a bug in client id decoding.
4052 Used to decode wrong buffer.
4054 * silc_server_channel_message checks now both local and global
4055 list for channel entry.
4057 * Tested channel joining (hence JOIN) in router environment
4058 successfully. Tested with two routers, two servers and two
4061 * Tested channel message sending in router environment successfully.
4063 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Added silc_server_save_channel_key into server.[ch] to save the
4066 received channel key in Channel Key payload processing. It is
4067 also used in JOIN command reply handling.
4069 Equivalent function silc_client_save_channel_key added into
4070 client.[ch] into client library.
4072 * Changed JOIN command reply to send information whether the channel
4073 was created or not (is existing already) and the channel key
4074 payload. Changed protocol specs accordingly.
4076 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4077 the request was sent by ID and not by nickname. Crashed on
4080 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4083 now correctly save the received data.
4085 * silc_server_free_sock_user_data now notifies routers in the
4086 network about entities leaving the network.
4088 At the same time implemented functions silc_server_remove_id
4089 and silc_server_send_remove_id to receive and send REMOVE_ID
4090 packets. The packet is used to notify routers in the network
4091 about leaving entities. The ID removed will become invalid in
4094 * Added function silc_idlist_del_server into server. Removes and
4095 free's server entry from ID list.
4097 * silc_server_private_message function now checks, if we are router,
4098 that the destination ID really is valid ID, naturally.
4100 * In router when NEW_ID packet is received (for new client) the
4101 hash of the Client ID is saved in the ID Cache but the
4102 client->nickname is set to NULL, instead of putting the hash
4105 IDENTIFY command now also checks that client->nickname must be
4106 valid. If it is not if will request the data from the server who
4107 owns the client. Added new function
4108 silc_server_command_identify_check.
4110 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4111 to set the command to already allocated Command Payload.
4113 * Tested private message sending in router environment with two
4114 routers, two servers and two clients. Fixed minor bugs and now
4117 * Fixed segfault from client's NAMES command. Used to crash if
4120 * Forwarded packets must not be routed even if it is not destined
4121 to the receiver. Changed server code comply with this.
4123 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Added `require_reverse_mapping' boolean value to ServerParams
4126 structure. If TRUE (not default) the server will require that
4127 the connecting host has fully qualified domain name.
4129 If the reverse mapping is not required and hostname could not be
4130 found the IP address is used as hostname.
4132 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Implemented version string checking to both client and server.
4135 The check is incomplete currently due to the abnormal version
4136 strings used in development version of SILC.
4138 * Changed all command functions in server to use the new
4141 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Changed char *data to unsigned char *data in ID Cache system to
4144 support binary data as ID Cache data. Changed code to support
4145 binary data in lib/silccore/idcache.c.
4147 * Renamed silc_server_packet_relay_command_reply to
4148 silc_server_command_reply as it is normal packet receiving
4149 function. Rewrote the function to accept command replys for
4150 servers and not only for clients.
4152 * Mark remote router always as registered server if we are connecting
4153 to it. Otherwise, commands sent by the router to us are ignored.
4155 * All ID List find routines now returns the ID Cache Entry pointer
4156 as well if requested.
4158 * WHOIS command works now in router environment, tested with two
4159 routers, two servers and two clients.
4161 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4162 in router environment (as it is almost equivalent to WHOIS) but
4163 hasn't been tested thoroughly. Added new functions:
4165 silc_server_command_identify_parse
4166 silc_server_command_identify_send_reply
4167 silc_server_command_identify_from_client
4168 silc_server_command_identify_from_server
4170 * Disabled route cache adding because adding two different ID's with
4171 same IP replaces the old cache entry thus giving wrong route.
4172 The entry->router->connection is always the fastest route anyway
4173 so route cache may not be needed. Of course, new routes maybe
4174 established after receiving the ID when the entry->router->connection
4175 might not be anymore the most optimal.
4177 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Add route cache for received ID for fast routing.
4181 * Added silc_server_packet_route to route received packet on router
4182 that is not destined to us.
4184 * Renamed silc_server_get_route to silc_server_route_get.
4186 * Added id_string and id_string_len fields into SilcServer to
4187 include encoded ServerID for fast comparing without excess
4188 encoding of the ID's.
4190 * Cleaned up WHOIS command on server side. Added following static
4193 silc_server_command_whois_parse
4194 silc_server_command_whois_check
4195 silc_server_command_whois_send_reply
4196 silc_server_command_whois_from_client
4197 silc_server_command_whois_from_server
4199 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4200 arguments in command replies. All command functions should be
4201 updated to use this macro.
4203 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Minor typo fixes on command reply handling on server.
4207 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Added silc_server_command_add_to_channel internal routine to add
4210 the client to the channel after router has created the channel and
4211 sent command reply to the server.
4213 * Added generic silc_server_send_command to send any command from
4216 * Use static buffer with ID rendering instead of duplicating data.
4218 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Fixed a channel user mode bug when joining to a channel server gave
4221 everybody channel founder rights, oops.
4223 * We mark ourselves as the router of the incoming server connection
4224 if we are router ourselves. This way we can check in some packet
4225 sending functions whether it is locally connected server. For
4226 incoming router connections we put NULL.
4228 * For router sending packets locally means now always sending the
4229 packet cell wide; to local clients and local servers. For normal
4230 server sending packet locally means sending it to only local
4233 * Fixed the JOIN command to really work in router environment. If the
4234 channel is created it is always created by the router. Router is
4235 also responsible of making the initial joining to the channel,
4236 sending JOIN notify to the sending server and distributing
4237 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4238 does not exist server doesn't do anything else but forward the
4239 command to the router which performs everything.
4241 * Added silc_server_send_channel_key function to send the Channel Key
4244 * Added silc_server_create_channel_key to create new channel key. The
4245 channel key is now re-generated everytime someone joins or leaves
4246 a channel, as protocol dictates. Note: channel->key_len is the
4249 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4252 packet_receive.[ch] to separate packet sending and receiving
4253 routines. The server.[ch] now includes everything else including
4254 actual packet processing (writing and reading data) and other
4257 Renamed silc_server_private_message_send_internal to
4258 silc_server_send_private_message. The routine is still though
4259 used only to relay private messages as server does not send
4260 private messages itself.
4262 Renamed silc_server_new_channel to silc_server_create_new_channel
4263 and added new function sicl_server_new_channel that handles the
4264 incoming New Channel packet. Added also new sending function
4265 silc_server_send_new_channel to send New Channel Payload.
4267 * Added new function silc_server_notify to process incoming notify
4268 packet to the server/router. Server may then relay the notify
4269 to clients if needed.
4271 * Added new function silc_server_new_channel_user to process incoming
4272 New Channel User packet. Router will redistribute the packet and
4273 send JOIN notify to its local clients and locally connected servers
4274 if needed. Normal server will send JOIN notify to its local client
4275 on same channel when received this packet. Added also corresponding
4276 sending function silc_server_send_new_channel_user to sent the
4279 * Added boolean route argument to send_notif_to_channel and
4280 packet_send_to_channel functions to attempt to route the packet
4281 if it is TRUE and send only locally if it is FALSE.
4283 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * silc_server_replace_id now broadcasts the received replace ID
4286 packet if it is not broadcast packet already. The router must
4287 broadcast to inform other routers about changed ID.
4289 * Added backpointer to server's router into SilcServer context in
4290 silcd/server_internal.h.
4292 * Fixed silc_server_packet_broadcast to send correct broadcast
4295 * The channel key is now distributed to the local client as soon
4296 as it is received from the router (in router environment) so that
4297 no other packet may be sent for the channel until client has
4300 * silc_server_remove_channel_user now broadcasts the received
4301 Remove Channel User packet if it is not broadcast packet already.
4302 The router must broadcast to inform other routers about removed
4305 * Added users field into SilcPacketContext that is a reference count
4306 of the context. One can increase the reference count by calling
4307 silc_packet_context_dup which is now changed to just increase the
4308 reference count instead of duplicating the data. The reference
4309 count is decresed by calling silc_packet_context_free that will
4310 free the data after the reference count hits zero.
4312 For now on the packet context and everything allocated into it
4313 (including the raw packet from network) must be freed by calling
4314 the new silc_packet_context_free function. Added also new function
4315 silc_packet_context_alloc that must be used now to allocate the
4316 context. This also means that if a routine is asynchronous from
4317 silc_[client/server]_packet_parse_type the packet context must
4318 be duplicated by calling silc_packet_context_dup. Otherwise it
4319 gets free'd after silc_[client/server]_packet_parse_type returns.
4320 Also, one must remember that if packet is duplicated then its
4321 reference count must be decresed by calling the free function as
4322 many times as it was duplicated.
4324 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4325 from both client and server.
4327 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Made joining to a channel working in router environment.
4331 * Cleaned up JOIN command on server side and create function
4332 silc_server_command_join_channel internal routine to make the
4335 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Changed silc_command_pending list to SilcDList. Also, added
4338 `ident' field to SilcServerCommandPending structure to identify
4339 the reply and to call correct callback.
4341 Added silc_server_command_pending_check function to replace the
4342 corresnponding macro. The silc_command_pending list is not
4345 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4346 to set identifier to previously allocated Command Payload. It
4347 is used to set identifier for command when resending Command
4350 * Added silc_command_payload_encode_payload to encode Command
4351 Payload buffer from SilcCommandPayload structure.
4353 * Added silc_argument_payload_encode_payload to encode Argument
4354 payload buffer from SilcArgumentPayload structure.
4356 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Changed WHOIS command to support router connection on server side.
4359 The whois request is always sent to router unless the server is
4360 standalone server. After server has received the reply from the
4361 router will it send the reply to the client.
4363 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4364 broadcast received broadcast packet. The function is used only
4365 by router. The broadcast packet is always sent to the router's
4368 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4369 render given ID to printable string, for log files for example.
4371 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Made basic router to router connections working. At least they
4374 can now connect to each other but nothing really works the way
4375 they are supposed - yet.
4377 * Added new initiator token to RouterConnection configuration
4378 file in silcd/serverconfig.[ch]. It is used to tell whether we
4379 are the initiator to the remote router or whether we'll expect
4380 the other end to connect.
4382 * Moved registering of listener task to silc_server_init, hence
4383 the server starts listenning as soon as it is run, even if it
4384 does not have connections to other routers. Let's see how well
4387 * Changed default connection retry timeouts for more suitable in
4390 * Removed cipher and such arguments from silc_idlist_add_client
4391 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4392 Added new function silc_idlist_add_data to add the keys and stuff
4395 * Added SilcIDListData structure and added it to SilcClientEntry
4396 and SilcServerEntry as their first field in the structure. This
4397 way we can explicitly cast the ID entries to the SilcIDListData
4398 structure and get common data for the entries. In past, we had
4399 to first check what type of connection it is and then cast it to
4400 correct ID entry type. Now, we can directly cast the opaque
4401 pointer to the SilcIDListData (no matter what ID entry it actually
4402 is) and get the data needed.
4404 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4407 in some circumstances even if threre were timeout tasks, though not
4408 IO tasks, but tasks anyway. Now fixed.
4410 * Defined SilcServerConnection structure to hold connection specific
4411 stuff about directly connected servers and routers. The definition
4412 is currently in silcd/server_internal.h. I thought about having
4413 a bit more important role fro this struct but for now it is used
4414 only when connecting to other server (or router actually).
4416 * Added connecting retry support in server when connecting to
4417 router(s). The retry feature implement exponential backoff
4418 algorithm. Also, added SilcServerParams structure to hold default
4419 parameters for server. For now, it include these retry settings
4420 and are hard coded. After server is moded to be as Silc Server
4421 Library this structure will be more important.
4423 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Changed client librarys channel->clients table to SilcList and
4426 changed code accordingly.
4428 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Changed client's channel table to SilcList and changed code
4431 accordingly. Also changed SilcChannelClientEntry to include back-
4432 pointer to the channel so that client entry can use that structure
4433 as list as well and we have fast cross-reference to the channel.
4434 This change dramatically decreased the complexity of channel
4435 handling with client entry and vice versa (removed one extra
4436 loop when searching for channel entry from many functions).
4438 * Changed server->sim from table to SilcDList and changed code
4441 * NAMES command can now be used from user interface. It will show
4442 the user list on the channel, neatly.
4444 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4445 Code now saves realname of the user if it becomes available.
4447 * Renamed configure.in to configure.in.pre and made ./prepare
4448 script to automatically add correct version string to
4449 configure.in which it creates from configure.in.pre.
4451 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * NAMES command reply now shows users mode with the nickname when
4456 * Moved silc_client_ch[u]mode[_char] functions from
4457 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4458 place sucks, they are utility functions and should be in some
4461 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4463 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4466 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Added TRQ (efficient deque and list library) into lib/trq. This is
4471 a very good list library that is currently used in the SILC. Defined
4472 SilcList API over the library because I didn't like the API very
4473 much. See lib/trq/silclist.h for the API and examples of how to
4474 use the API. Fixed various places in the code to use the new
4475 SilcList API. The SilcList is meant for lists that has a structure
4476 already defined as a list. It is not suitable to add just some
4477 context to the list (in TRQ, the context is the list actually).
4479 So, I defined SilcDList that can be used for the purpose where
4480 predefined list structure does not exit. This can be used as
4481 such list. Now some context just can be added to the SilcDList.
4482 Currently this list is not used in the SILC just yet, though there
4483 are a lot places where this can replace dynamically allocated
4484 tables and I will fix these places, later, to use SilcDList.
4485 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4486 and use TRQ internally).
4488 Also fixed some annoying warning messages that the original TRQ
4489 code generated. Also minor changes to TRQ's Makefile.in.
4491 * Added support for querying by Client ID to both WHOIS and
4492 IDENTIFY commands into server, as required by the protocol.
4494 * Removed method function pointers from SilcBuffer structure. They
4495 weren't used to anything and just increased the context size for
4496 no good reason. This change also made silc_buffer_alloc and
4497 silc_buffer_free functions inline functions.
4499 * Disabled command flooding detection support until it's fixed so
4500 that it accepts commands in but does not execute them more than once
4503 * Added silc_net_localhost(), to return local hostname, into
4504 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4505 that must be initialized before calling silc_client_init.
4507 * Added new function: silc_server_send_notify_on_channels to send
4508 notify messages to all channels client has joined. It is assured
4509 that the message is sent only once per client.
4511 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4512 lib/silcutil/silcutil.[ch] as silc_format function. The new
4513 function is generic and is used by server as well, not only by
4514 the logging routines.
4516 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4517 the provided version string was not acceptable. Added new function:
4518 silc_ske_check_version into lib/silcske/silcske.h. The function
4519 must be implemented by the application (client or server) and it
4520 does not reside in the SKE library. The function checks the version
4521 string remote end sent.
4523 * Added back pointers (to opaque context and to SilcSocketConnection)
4524 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4526 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4527 duplicate packet context structure.
4529 * Changed `notify' client operation to send same arguments as client
4530 receives from server except for ID's. ID's are mapped to correct
4531 ID entry and that is returned. Also, if channel entry is not sent
4532 by server but the notify is for channel the channel entry is sent
4533 to application (otherwise application doesn't know that it is for
4534 channel (library gets it from packet's Destination ID)).
4536 * Added silc_client_remove_from_channels into client library to
4537 remove a client from all channels it has joined to. Used when
4538 received SIGNOFF notify from server. Added also new function
4539 silc_client_replace_from_channels to replace old ID entry with
4540 new ID entry on all channels. Used when received NICK_CHANGE
4543 * Fixed ID Cache list handling in silc_idlist_get_client in
4544 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4545 to get (or query) client by ID.
4547 * Updated TODO list.
4549 * Added connection authentication status message defined by the
4550 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4551 support for these into the code in client and server side.
4553 * Added generic function silc_client_send_command to send any command
4554 with variable argument list. Application should use this function
4555 to send commands if the command functions provided by the library
4556 does not suite for the application's user interface needs.
4558 * Added new `failure' client operation. Application is notified about
4559 received failure packet if client is executing a protocol. In this
4560 case the protocol's execution has failed.
4562 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4563 is required by the protocol.
4565 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4566 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4569 * Added status flag to SilcSKE object to indicate realtime status
4570 of the SKE protocol.
4572 * Application receives now exactly same command reply arguments as
4573 the library receives from server. However, if ID is received the
4574 corresponding ID entry is returned to the application (eg. Client
4575 ID is mapped to correct SilcClientEntry entry and that is returned).
4576 Changed command_reply client operation due to this change.
4578 * Changed all ID's in commands and in command replys as ID Payloads.
4579 Change affected both client and server side codes.
4581 All ID's sent in SILC network (with execption of ID's in SILC
4582 Packet header) are sent in ID Payload to support variable length
4585 * Server now notifies nick changes and notifies all clients on
4586 the channels about the new nickname (about the new Client ID,
4589 * Implemented CMODE command to change channel modes. Supports all
4590 channel modes defined by the protocol specs except ban and invite
4591 lists. (Also, private channel key mode is supported but support for
4592 setting private channel key in client is missing, thus, this mode
4593 has no effect on client side (except that server requires that the
4594 client uses private channel key and normal channel traffic does not
4597 Also, invite mode works per se, but INVITE command does not work
4598 yet correctly, so you can set channel as invite only channel but
4599 inviting clients to the channel does not work (it is yet to be
4600 thought what's the best way to do it).
4602 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4603 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4604 Implemented CUMODE command to change user's mode on the channel.
4605 Supports all modes defined by the protocol specs.
4607 * Added NAMES command reply to return users modes on the channel.
4609 * Removed unnecessary and slow ciphers from lib/silccrypt.
4611 * Set SO_KEEPALIVE option to connection sockets by default.
4613 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4615 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4616 redefined the Notify Payload into protocol specs.
4618 * Added silc_id_payload_parse_id to get ID directly from raw
4621 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4624 accept searching by Client ID as well.
4626 * Added support for LEAVE and SIGNOFF notify types in client library.
4628 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4629 to parse ID Payload from raw data.
4631 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added flags parameter into silc_ske_assemble_security_properties
4634 function in lib/silcske/silcske.[ch].
4636 * Changed notify client operation to fit better for notify messages
4637 sent by server. The notify payload received from server is now
4638 passed to the application (after parsing it to SilcNotifyPayload).
4639 It is application's responsibility to retrieve the arguments
4640 from the payload and show the message the way it wants. The message
4641 sent by server is implementation specific.
4643 * Changed public keys to comply with the protocol specification.
4644 Old public keys are not supported anymore and are not compatible.
4646 * Removed nickname from Channel Payload as the latest draft removed
4647 it. The client must resolve the nickname from the NAMES command
4648 reply received when it joined the channel.
4650 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4652 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Fixed some errors in protocol specification drafts.
4656 * Created lib/silccore/silcnotify.c to implement Notify Payload
4657 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4658 generic payloads described by protocol specifications. The file
4659 includes implementations for ID Payload and Argument Payload.
4661 * Changed Command Payload implementation to use the new Argument
4662 Payload. Changed command_xxxx_payload to command_payload_xxxx
4663 to comply with SILC coding conventions.
4665 * Added suppport for Argument Payload handling in Notify Payload
4666 implementation as protocol requires it. Added the new support
4667 into server and client lib as well.
4669 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Added support for multiple nicknames on same channel. [n] is
4672 added locally to the nickname if there are more than one same
4673 nicknames on the channel.
4675 * Server now sends all nicknames that matched WHOIS request.
4676 Client also shows the list received from server.
4678 * Added TOPIC command to client side. User can now set and show
4679 current topic on channel.
4681 * Added MOTD command to client and server. Also, server sends the
4682 motd when client connects to the server.
4684 * Changed version strings to comply ISO 8601.
4686 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Fixed protocol error handling in client library. It should now
4689 cope even if the SKE fails for some reason.
4691 * Made new protocol specification drafts for submitting to IETF.
4693 * Implemented TOPIC command to server in silcd/command.c.
4695 * Added two new notify types into lib/silccore/silcnotify.h:
4696 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4697 notify nickname change and topic setting/change on a channel.
4699 * API change of command_reply operation in client library. The
4700 application gets now the status type received from server as well.
4702 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4706 * Cras fixed and optimized the packet handling even further and
4707 it should work now. Minor change to the prototype of function
4708 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4710 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added new function into lib/silcutil/silcschedule.[ch]:
4713 silc_schedule_with_fd to select() a specified fd. The function
4714 returns after timeout expires or data arrives or goes. The
4715 function is used by packet routines to wait that all data is
4716 received from network.
4718 * Fixed data reading from network in lib/silccore/silcpacket.c.
4719 The code now assures that all data is read from the fd and then
4720 continues packet processing. This was a bug fix since the code
4721 used to drop some data in some circumstances.
4723 * Added new function into lib/silcclient/client.[ch]:
4724 silc_client_start_key_exchange to start key exchange after
4725 connection has been established to server. The code internally
4726 now uses this funtion but its main purpose was to provide it
4727 for applications that perform their own connecting. After
4728 application has created a connection it merely calls this
4729 function to start the key exchange between client and server.
4730 The library takes care of everything else after that.
4732 Updated also lib/silcclient/README to explain the usage of
4735 * Do not send to application information that connection has
4736 been established. Application gets notified it by connect
4739 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Applied cras's patch to add silc_schedule_one function. The
4742 function runs scheduler once and returns.
4744 * Fixed the scheduler after cras messed it up. The timeout
4745 handling works now as it's supposed to work.
4747 * Added into lib/silccore/ silcnotify.h to include notify
4748 message types support. Changed silc_server_send_notify*
4749 functions, in server.[ch], to support those new notify types.
4750 Added the support for the notify types into client library,
4751 as well. Added new notify client operation into ops.h in
4754 * Changed silc_server_packet_send_to_channel to send normal
4755 packets instead of just channel message packets. The function
4756 is now used to send the notify packets to channels. It is not
4757 used to send channel message packets anymore, as server never
4760 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4761 va_arg()s as it seems to require it nowadays. I guess, if SILC
4762 is compiled with older va_arg() the new code should work anyway.
4764 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Splitted core library. Core library (lib/silccore) includes
4767 now only SILC protocol specific core (and common) components.
4768 Created new utility library (lib/silcutil) that includes more
4769 generic purpose stuff. The stuff for util library was taken
4770 from the old core library. This was minor and easy split.
4772 * Created SILC Client Library (lib/silcclient) that includes
4773 implementation of the SILC client without user interface. This
4774 was major move from silc/ directory. The code has been changed
4775 so that it is transparent towards the user interface. The
4776 silc/ directory includes now the same user interface as before
4777 and it uses the new client library. Read lib/silcclient/README.
4778 Basicly, the client library performs everything else related
4779 to SILC except user interface handling. Also, configuration
4780 files are considered to be part of user interface and library
4781 does not handle them.
4783 This change also changed a lot of structures, function naming etc.
4784 Most important change was that SilcClientWindow object was
4785 renamed to SilcClientConnection in the client library. Created
4786 also new file lib/silcclient/ops.h. Also added new files
4787 silc/local_command.[ch] and silc/client_ops.[ch].
4789 All these changes were made to make it easier for user interface
4790 designers to create what ever user interface for the SILC client
4793 It is also expected that the server will be moved to lib
4794 directory as well and SILC Server Library will be created;
4795 sometimes in the future.
4797 * Removed Local commands from lib/silccore/silccommand.h as
4798 they are application specific and new client library does not
4799 handle any of those anymore.
4801 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4802 old client implementation in silc/.
4804 * Added support for callback functions in SILC_LOG_* macros.
4805 Application can now set its own callbacks that will be called
4806 instead of using the default functions that will always print
4807 the debug messages to stderr (or stdout). Also, debugging can
4808 now be disabled by setting silc_debug to FALSE and re-enabled by
4809 setting it to TRUE. Note, that logging will still work even
4810 if debugging is disabled.
4812 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4813 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4814 silc_log_reset_debug_callbacks.
4816 * To enable debugging in silc client one must give now -d
4817 option on command line.
4819 * Changed silc_schedule_init to automatically allocate task queues
4820 if they are not allocated before calling it.
4822 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Added GMP 3.1 into math library.
4826 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4829 a channel in SILC network. The packet is used by servers and
4830 routers to notify other routers that user has left a channel.
4831 This little feature was missing until now. Added the feature
4832 to protocol specification as well.
4834 Added functions: silc_server_send_remove_channel_user and
4835 silc_server_remove_channel_user into server.[ch].
4837 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4838 lib/silccore/silcpacket.h. However, they are not implemented
4841 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Fixed joining to a channel and sending channel messages
4844 between server and router. The channel message sending should
4845 now work inside a cell.
4847 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Fixed the private message sending between server and router.
4850 The private message sending should now work inside a cell.
4852 * Added silc_server_replace_id into server.[ch] to replace
4853 existing ID in the SILC network.
4855 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4856 and silc_idlist_replace_server_id into idlist.[ch] in server.
4858 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Fixed the server to server connections. Server can again now
4861 connect to router. Router to router connections probably does
4864 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4866 * Added dynamic protocol registering support. Now protocols can
4867 registered and unregistered on the fly. Patch by cras.
4869 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added lib/contrib directory to hold routines that some platforms
4872 don't have but are needed by SILC.
4874 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4875 into lin/contrib to provide getopt() and getopt_long() for
4876 those who don't have it.
4878 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Added AWAY command to client. When away message is set and
4881 client receives a private message packet the client automatically
4882 replies to the sender with the away message.
4884 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4885 bug seemed to be the cause of recent problems when compiling
4888 * Added version detection support to SKE protocol specification
4889 and added the new changes to the SKE implementation as well.
4890 There were other minor changes in the SKE protocol as well.
4892 Many changes in lib/silcske/silcske.[ch] and in
4893 lib/silcske/payload.[ch].
4895 * Added ^U functionality, clear input line. Patch from cras.
4897 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Mainly small bugfixes on core library. Fixed some debugging
4900 logging and buffer overflow in silclog.c.
4902 * Updated config.sub and config.guess on the distribution tree.
4904 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Added command lagging support in server. Client may execute
4907 commands now only once in two seconds.
4909 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Optimized packet reception. MAC computation and checking is now
4912 also more optimized. A lot previously duplicated code is now
4913 used as generic by both client and server.
4915 * Fixed key pair generation in clientutil.c
4917 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Added into lib/silccore/silcbufutil.[ch] new function;
4920 silc_buffer_realloc.
4922 * Moved generic packet sending/encryption functions to
4923 lib/silccore/silcpacket.[ch] from client and server. Some
4924 rewriting of the functions.
4926 * Moved all generic packet reception/decryption functions to
4927 lib/silccore/silcpacket.[ch] from client and server. The
4928 packet processing is now much cleaner in both client and server.
4929 These were major changes in both client and server.
4931 * Created many common functions in server to do packet sending.
4932 Previously code were duplicated a lot, this has been removed
4935 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Rewrote major parts of the ID cache system. Don't know
4938 whether it is better now or not but at least the API is more
4941 * Major rewrite on ID cache stuff on client because of the ID
4942 cache API changes. Added idlist.c to client.
4944 * Also major rewrite on ID cache stuff on server as well.
4945 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4946 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4947 in hand, instead they are all put into the ID cache system now.
4948 All server_idlist_* routines uses ID cache now instead of
4949 traversing its own lists (those lists does not exist anymore).
4950 SilcIDList though still exists. Also, SilcXXXEntry's are
4953 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Finally made the SKE implementation compliant to the protocol
4956 specification. All mp integers are now binary encoded as
4957 opposed being HEX encoded.
4959 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4962 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4963 functions: silc_[encode/decode]_pem. Also added function
4964 silc_encode_pem_file to PEM encode with newlines ('\n') for
4967 * SILC public keys are now encoded either PEM or binary. Same
4968 option is for private keys as well. By default private keys
4969 are binary encoded and public keys PEM encoded. Silly HEX
4970 encoding were removed.
4972 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4973 function to create fingerprints.
4975 * Fixed a bug in SHA1; does not change the original data anymore.
4977 * Partly implemented INFO command on client and server side.
4978 Fixed CLEAR command. Changes to SERVER command; show current
4979 server(s) when giving command without arguments. Added
4980 VERSION command to client.
4982 * Added check to server that unregistered connections cannot
4983 execute commands (unless it is specificly allowed).
4985 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Fixed screen refresh.
4989 * Fixed channel joining bug from client. On some circumstances
4990 client tried to join to a channel it had already joined.
4992 * Added public key verification process into client's protocol.c.
4993 The client now verifies the public key from user and saves
4994 it into ~./silc/serverkeys/ directory.
4996 Added into: clientutil.[ch]: silc_client_verify_server_key.
4998 * Changed SKE protocol's silc_ske_initiator_finish function
4999 to accept callback function that verifies the received public
5000 key. Removed old silc_ske_verify_public_key function.
5002 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5005 silc_pkcs_private_key[_data]_set.
5007 * Made the password and public authentication more cleaner in
5008 server's protocol.c.
5010 * Removed historic and obsolete protocol `channel_auth' from
5011 both client and server.
5013 * Removed wrong way of sending command status messages from
5014 server to client in server's command.c. The old way violated
5015 protocol specification.
5017 Changes to silccore/silccommand.[ch]: removed
5018 silc_command_encode_status_payload -> not needed anymore,
5019 changed silc_command_encode_payload_va to accept extra
5020 argument on variable argument list. The argument type must
5021 now be provided to the function. Also, added new function:
5022 silc_command_encode_reply_payload_va which is same as
5023 normal command_encode_payload_va except command status type
5024 is provided as extra argument.
5026 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5028 * Added ~./silc directory handling. The directory includes the
5029 public and private keys for the client.
5031 Added silc_client_check_silc_dir, silc_client_create_identifier
5032 and silc_client_load_keys.
5034 * Implemented SILC protocol compliant public key. Added public
5035 and private key saving to and loading from files.
5037 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5038 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5039 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5040 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5041 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5043 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5044 silc_pkcs_load_[public/private]_key.
5046 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added silc_server_get_route (route.[ch]) to get connection
5049 data for the fastest route for given ID.
5051 * Implemented INVITE command on client and server. The command
5052 were re-defined in the SILC Protocol Specification and the
5053 implementation now complies with the specification.
5055 * Implemented PING command on client and server.
5057 * Implemented NAMES command on client and server. The server side
5058 supports currently only normal server not router server yet.
5059 Some changes to NAMES definition in SILC protocol specification.
5061 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Implemented LEAVE command on client and server.
5065 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5066 again. This change was made to the protocol as well. Server
5067 should not violate the protocol specification anymore.
5069 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5072 was tested. SOCKS4 was not but should work anyway.
