1 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed Irssi SILC client's KILL command's HELP syntax.
5 * The USERS command now resolves the detailed user information
6 if the userinfo field is missing. Affected file is
7 lib/silcclient/command_reply.c.
9 * Do not print error in silc_file_read if the read file does
10 not exist. Just silently return NULL. Affected file is
11 lib/silcutil/silcutil.c.
13 * Fixed the silc_log_output to not wine about NULL filename
14 and to not create some bogus " " filename. Affected file is
15 lib/silcutil/silclog.c.
17 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
19 * Fixed various printing bugs on the user interface in the
20 Irssi SILC Client. Minor changes that were forgotten from
23 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
25 * Fixed the configure.in.pre and the compilation and distribution
26 environment to support the new autoconf 2.52. That version is
27 now required to compile the CVS trunk.
29 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
31 * Renamed function silc_parse_nickname to silc_parse_userfqdn
32 to generally parse user@fqdn format strings. Affected file
33 lib/silcutil/silcutil.c.
35 * Added nickname_format and nickname_force_format fields to the
36 SilcClientParams structure. The first one defines the format
37 for the nicknames that the library will enforce if the receives
38 multiple same nicknames. The second one is boolean value and
39 can be used to force the library to always enforce the format
40 to the nicknames regardles whether there are multiple nicknames
41 or not. This configurable formatting was employed to flexibly
42 support accessing multiple nicknames from the user interface.
43 The userinterface can now set the nicknames to what ever format
44 they prefer. Affected file lib/silcclient/silcapi.h.
46 Added function silc_client_nickname_format to the file
47 lib/silcclient/idlist.c. It performs the nickname formatting.
49 Added new field `hostname´ to the SilcClientEntry context.
50 It holds the hostname of the client. Affected file is
51 lib/silcclient/idlist.h.
53 * Irssi SILC Client sets the nicknames in nick@hostn format.
54 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
55 irssi/src/silc/core/silc-core.c.
57 The WHOIS printing now also shows both the real nickname and
58 the formatted nickname so that user knows how to access the
59 user if there are multiple same nicknames cached. Affected
60 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
61 printing formatting too to take the hostname now as a separate
62 argument. The Affected file is
63 irssi/src/fe-common/silc/modules-formats.[ch].
65 * Changed the silc_client_get_clients_local to accept the formatted
66 nickname as argument. It accepts the real nickname too but the
67 formatted nickname can be used to find the true entry from
68 multiple entries. Affected file lib/silcclient/silcapi.h and
69 lib/silcclient/idlist.c.
71 * Added nickname_format_parse field to the SilcClientParams.
72 It is a callback function provided by the application to parse
73 the nickname out of the formatted nickname string. The library
74 calls it to get the nickname from the formatted string. Since
75 the application generally knows better the format of the nickname
76 string it parses it instead of the library, even though library
77 encodes the formatted string. If the callback function is not
78 provided then the library will use the string as is. The
79 affected file is lib/silcclient/silcapi.h.
81 * All the nickname strings passed to the client library in
82 commands are now expected to be formatted nickname strings.
83 If the command does not support the formatted nickname string
84 it will assume that the sent string is the actual nickname.
85 Affected file lib/silcclient/command.c.
87 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
89 * Added public key authentication support to OPER and SILCOPER
90 commands in the client library. Affected file is
91 lib/silcclient/command.c.
93 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Changed the get_auth_methdod client operation to be asynchronous.
96 It can be async if the application resolves the authentication
97 method from the server during the negotiation. Added new
98 SilcGetAuthMeth completion callback that the application will
99 call after resolving the authentication method.
101 Added function silc_client_request_authentication_method that
102 the application can use to resolve the authentication method
103 from the server. Added also SilcConnectionAuthRequest callback
104 that the library will call after the server has replied. The
105 application can call this function if it does not know the
106 current authentication method.
108 Affected files are lib/silcclient/client.c and
109 lib/silcclient/silcapi.h.
111 * The Irssi SILC client now automatically resolves the authentication
112 method incase any configuration information is not present (and
113 currently there never is). The affected file is
114 irssi/src/silc/core/client_ops.c.
116 * Fixed public key authentication from the client library.
117 Affected file lib/silcclient/protocol.c. Changed also the
118 protocol specification about the public key authentication in
119 the connection authentication protocol. The actual data to be
120 signed is now computed with a hash function before signing.
122 * Fixed the public key authentication from the server as well.
123 Affected file silcd/protocol.c.
125 * Removed the mlock()'s from the memory allocation routines.
126 Affected file lib/silcutil/silcmemory.c. The ./configure does
127 not check anymore for the mlock(). Affected file is
130 * Fixed USERS command in server to allow the execution of the
131 command for private and secret channels if the client sending
132 the command is on the channel. Affected file silcd/command.c.
134 * Fixed silc_client_get_clients_local to return the clients
135 count correctly. It could return wrong value. Affected file
136 lib/silcclient/idlist.c.
138 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
140 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
141 types. The assembler optimizations seemed not to like 64-bit
142 data types. The assmebler optimizations thus are now enabled
143 also for BSD systems as opposed to only enable them for Linux.
145 * Do not check for threads at all on BSD systems. Affected
146 file configure.in.pre.
148 * Removed -n and -h options from the Irssi SILC Client since
149 they are not used in silc.
151 * Fixed the prime generation to assure that the first digit
152 of the generated random number is not zero since our conversion
153 routines does not like number strings that starts with zero
154 digit. If zero digit is seen the random number is regenerated.
155 This caused some corrupted RSA keys when the zero first digit
156 was met. Affected file lib/silcmath/silcprimegen.c.
158 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
160 * Fixed WIN32 configuration in the ./configure script.
161 Fixed to include xti.h on environments that has it.
162 Patches by Carsten Ilchmann and andrew.
164 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
166 * Changed the silc_id_create_client_id to be collision
167 resistant. It is now assured that there cannot be created
168 two same client ID's. I suspect that some weird bugs in
169 the server were actually caused by duplicate Client IDs.
170 Affected file silcd/serverid.[ch]. A router receiving
171 new ID now also assures and informs the sending server
172 if the ID caused collision.
174 * Changed the silc_id_create_channel_id to also assure that
175 there are no collisions.
177 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Statement about ignoring the Mutual Authentication flag when
180 performing rekey with PFS was a bit misleading. It is ignored
181 if it was set in the initial negotiation, it cannot be even
182 set in the rekey. Fixed in the ke-auth draft. Started the
183 new versions of the protocol drafts in the doc/.
185 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
187 * Fixed a bug in silc_client_command_identify_save when saving
188 new channel information. The channel name was no duplicated
189 and caused crash on exit. Affected file is
190 lib/silcclient/command_reply.c.
192 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
194 * Fixed the getkey command handling in the server. Send just
195 empty OK reply to the sender if the key could not be fetched
196 (but everything else was ok, like the key just was not available).
197 Changed the public key parameter to optional in the protocol
198 specs so that empty OK reply can be sent. Affected file
201 Added a message to Irssi SILC client to tell to user if the
202 server did not return a public key.
204 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
206 * Fixed a channel key regeneration bug. It registered new
207 timeout tasks exponentially until all system resources were
208 used. Affected file silcd/server.c.
210 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
212 * Added the SILC Document generator to the scripts/silcdoc.
213 It can be used to generate the Toolkit Reference Manual out
214 of the source tree. Internally it will also use the RoboDoc
215 generator now imported in util/robodoc.
217 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
219 * Added couple of return's in rekey protocol if error orccurred
220 during the protocol. The execution must be terminated.
221 Affected file silcd/protocol.c. Also, terminate the protocol
224 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
226 * The client's Client ID was created initally from the wrong
227 nickname (it could have been in format nick@host) in the
228 silc_server_new_client. Affected file silcd/packet_receive.c
230 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
232 * Added some SILC_LOG_ERROR's to various error conditions
233 if client could not be added to ID cache. Affected files
234 silcd/packet_receive.c and silcd/server.c.
236 * When client's sock->user_data is freed, NULL also the
237 client->router and client->connection pointers. Added check
238 for these pointers being NULL to various places around the
239 code. Affected file silcd/server.c.
241 * Added client->data.registered == TRUE checks to various
242 places around the code to assure that unregistered client's
243 are not handled when it is not allowed. Affected file
246 * Added `bool registered' fields to all
247 silc_idlist_[server|client]_get_* routines to indicate whether
248 the fetched client needs to be registered or not. Affected
249 file silcd/idlist.[ch].
251 * Add your own entry as registered to the ID cache in the
252 server. Affected file server.c.
254 * Fixed a bug in silc_server_new_server. The SilcServer was
255 set as the new server's context instead of SilcServerEntry.
256 This naturally caused some weird bugs.
258 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Do not delete the channel rekey task when adding it
261 for in silc_server_create_channel_key.
263 * Changed the silc_server_create_channel_key to return
264 TRUE or FALSE to indicate the success of the channel key
267 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Fixed MSVC++ project files and added missing files to
270 Makefiles under win32/.
272 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
274 * Do not add TCP_NODELAY flag if the operating system
275 does not have it defined. Affected files are
276 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
278 * Fixed buffer overflow from Irssi SILC Client. Affected
279 file irssi/src/fe-common/core/themes.c.
281 * Fixed double free in client library in the file
282 lib/silcclient/client.c when disconnecting from server.
284 * Applied double free patch from cras to Irssi SILC client.
285 Affected files irssi/src/core/[modules/expandos].c
287 * Fixed the disconnection handling to Irssi SILC Client.
288 The application must call silc_client_close_connection
289 in ops->connect client operation in case of failure of
290 the connection. Affected file is
291 irssi/src/silc/core/client_ops.c.
293 * Do not set sock->protocol to NULL in the function
294 silc_client_close_connection after executing the protocol's
295 final callback since the sock might not be valid anymore.
296 Affected file lib/silcclient/client.c.
298 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
300 * Do not enable SILC_THREADS if the linking with libpthread
301 did not happen. Affected file configure.in.pre.
303 * Added notion to protocol specification that server must
304 verify the sent authentication payload with CMODE when
305 setting the channel founder key. Implemented it to the
306 server. Affected file silcd/command.c.
308 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Added _EXTRA_DIST SILC distribution variable to the
311 distributions file. It is used to conditionally add extra
312 files or directories to the specific distribution. Affected
313 files ./prepare, Makefile.am.pre and distributions.
315 Removed the `_' from the start of the distribution names.
318 * Added README.WIN32 for instructions to compile the Toolkit
321 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
323 * Fixed a double free in disconnection in the server. Affected
324 file is silcd/server.c.
326 * Fixed the lib/silcske/groups.c to work now also with GMP
327 MP library. The string conversion did not work when using
328 specific base and the base is indicated in the string as well.
330 * Created win32/ directory which now includes MSVC++ specific
331 stuff so that toolkit (DLLs) may be compiled with MSVC++.
332 It will appear only in the toolkit distribution
334 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
336 * Changed the key material distribution function in case when
337 the hash output is too short. The data is now concatenated
338 a bit differently than it used to. Made the change to the
339 SKE protocol specification.
341 * Added better GMP detection to configure.in.pre. A patch
344 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Fixed a minor bug in SKE that might cause some problem on
347 some platforms. Affected file lib/silcske/silcske.c.
349 * Added the cookie checking for initiator in the SKE. It checks
350 that the responder returns the sent cookie unmodified. The
351 affected file is lib/silcske/silcske.c. Added new SKE
352 error type INVALID_COOKIE that can be sent during the
353 negotiation. Fixed some memory leaks as well.
355 * Added the "invalid cookie" error message to Irssi SILC client's
358 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Added `task_max' field to the SilcClientParams to indicate
361 the maximum tasks the scheduler can handle. If set to zero,
362 default values are used. Affected file lib/silcclient/silcapi.h.
364 * Fixed memory leaks in silc_client_close_connection. Affected
365 file lib/silcclient/client.c.
367 * Added silc_client_del_client_entry to client library to free
368 all memory of given client entry. Affected file is
369 lib/silcclient/idlist.[ch].
371 * Added new functions silc_client_del_channel and
372 silc_client_del_server to delete channel and server entries.
373 Affected file lib/silcclient/[silcapi.h/idlist.c].
375 * Removed silc_client_del_client_by_id from silcapi.h.
377 * Fixed the INFO command to return the server's own info
378 correctly when querying by Server ID. Affected file is
381 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
383 * Removed the non-blocking settings in WIN32 code in the
384 silc_sock_[read/write] and added SleepEx instead. Affected
385 file lib/silcutil/win32/silcwin32sockconn.c. The availability
386 of input data is now checked with FIONREAD and ioctlsocket.
388 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
390 * Call silc_schedule_task_del_by_context in the
391 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
392 Affected file lib/silccore/silcprotocol.c.
394 * Call silc_protocol_cancel for active protocols in the
395 silc_server_close_connection if the funtion
396 silc_server_free_sock_user_data has not been called.
397 Affected file silcd/server.c.
399 * Generic tasks cannot be deleted using the del_by_fd
400 task deleting function since generic tasks does not match
401 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
403 * Added a notion to SILCOPER help file that the SILCOPER works
404 only on router server, not on normal server.
406 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
408 * Added for WIN32 support for the new scheduler as well.
409 Affected file lib/silcutil/win32/silcwin32schedule.c.
411 * Fixed the SHA1 implementation to work on various platforms.
413 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
415 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
416 API. It is part of the scheduler now. Everything else is
417 as previously but some functions has changed their names.
418 Checkout the lib/silcutil/silcschedule.h for the interface.
419 Updated all applications to use the new interface. Affected
420 files are lib/silcutil/silcschedule.[ch].
422 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
424 * Found a bug in the SKE implementation. The HASH value,
425 specified by the protocol, was not computed correctly. The
426 public key of the responder was not added to the computation
427 even though it is mandatory. Affected file lib/silcske/silcske.c.
428 This unfortunately causes incompatibilities with older
431 * Added WIN32 specific network init and uninit functions:
432 silc_net_win32_init and silc_net_win32_uninit to init and uninit
433 the Winsock2. Affected file lib/silcutil/silcnet.h and
434 lib/silcutil/win32/silcwin32net.c.
436 * Set the socket always to nonblocking mode on WIN32 after
437 reading data or writing data. Affected file is
438 lib/silcutil/win32/silcwin32sockconn.c.
440 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
442 * Fixed various compilation problems under WIN32. Affected
443 files lib/silcutil/win32/silcwin32thread.c and
444 lib/silcutil/win32/silcwin32schedule.c.
446 * Removed all _internal.h #includes from public header
447 files. Internal headers must never be included from
450 Removed also the lib/silcske/payload_internal.h file.
452 * All include files that may be needed (public and some others
453 included by the public headers) by application developers are
454 now copied to the ./includes directory. It does not copy any
455 internal headers. Affected file Makefile.defines.pre and all
456 Makefile.am's under lib/ and subdirs.
458 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
460 * Do not change the ~/.silc directory's permissions automatically.
461 Affected file irssi/src/silc/core/clientutil.c.
463 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Do not cancel the protocol in silc_server_close_connection
466 it might cause recursion. Now cancelled in the function
467 silc_server_free_sock_user_data. Affected file silcd/server.c.
469 * Fixed the silc_server_remove_clients_by_server to regenerate
470 the channel keys correctly finally. Added also new function
471 silc_server_remove_clients_channels to actually do it.
472 Affected file silcd/server.c.
474 * Fixed the silc_server_new_channel to not crash by giving
475 wrong router to the new channel. Affected file is
476 silcd/packet_receive.c.
478 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
480 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
481 which is given as argument to the silc_client_alloc now.
482 It can be used to configure the client and set various parameters
483 that affect the function of the client.
485 * The USERS command in server did not check whether the channel
486 is private or secret. Affected file silcd/command.c.
488 * Added new argument to the USERS command in protocol specification.
489 The USERS command now can take the channel name as argument
490 as well. Added support for this in client and server and
491 updated the protocol specs.
493 * Completed the GETKEY command in client. It can be now used
494 to fetch also servers public key not only some clients.
495 Affected files lib/silcclient/command[_reply].c.
497 * Added silc_client_get_server to return server entry by the
498 server name. Affected files lib/silcclient/silcapi.h and
501 * Redefined the IDENTIFY command in protocol specification to be
502 more generic. It now can be used to query information about
503 any entity in the SILC Network, including clients, servers and
504 channels. The query may be based either the entity's name
505 or the ID. Added support for this in both client and server.
507 Affected files silcd/command.c and lib/silcclient/command.c
510 * Optimized the WHOIS and WHOWAS commands in the server. Removed
511 the _from_client and _from_server functions. Affected file
514 * Added silc_client_get_channel_by_id_resolve to the file
515 lib/silcclient/silcapi.h to resolve channel information by
516 its ID. Added also silc_client_get_channel_by_id that
517 does not resolve it from the server.
519 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
521 * Added SilcServerEntry context into the client library
522 to represent one server. The INFO command now allocates
523 these to save the resolved server info. For now on the
524 client library will also keep information about servers,
525 connected and resolved with INFO.
527 The INFO command now allocates the SilcServerEntry context
528 and saves the server info there. The COMMAND_REPLY in
529 the INFO now returns the parameters to application in
530 same order as defined in the protocol specification.
532 The entries are cached in the client->server_cache.
534 * The INFO command is now issued after received the Client ID
535 from the server. Affected file lib/silcclient/client.c.
537 * The CMODE_CHANGE notify may now return also an SilcServerEntry
538 to the application as the mode changer might be server.
539 It is guaranteed that NULL is not returned anymore to the
540 application. Affected file lib/silcclient/client_notify.c.
542 The ID Type is now also passed to the application so that
543 it can check whether the returned entry is SilcClientEntry
546 Added new function silc_client_get_server_by_id to return
547 the server entry by ID. Affected files are the
548 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
550 * Do not create the channel in the Irssi SILC Client when issuing
551 the JOIN command but when received the sucessful JOIN command
552 reply. Otherwise the channel might get created even though we
553 could not join it. The Affected file is
554 irssi/src/silc/core/[silc-channels.c/client_ops.c].
556 * Fixed a channel joining bug in router. The router must also
557 check the channel modes, invite and ban lists etc. when serving
558 the JOIN command sent by normal server. Affected file is
559 silcd/command.c. The router now resolves the client's
560 information from the server who sent the JOIN command if it
561 does not know it, and processes the JOIN command only after
564 * Changed the SilcCommandCb to take new argument; void *context2.
565 Affected file lib/silccore/silccommand.h
567 The second argument in the command callbacks in the server now
568 includes the SilcServerCommandReplyContext if the command was
569 called as pending command callback from the command reply.
570 Otherwise it is NULL. When called as pending the status of the
571 command reply will be checked and if it was erronous the
572 error will be sent to the original sender of the command.
573 This way the client always receives the error messages even
574 though the server was actually the one who received the error
575 when it resent the command to router, for example. Affected
576 files silcd/command[_reply].[ch].
578 * Fixed sending WHOWAS command's error message to client if
579 the requested client could not be found. It was missing.
582 * Changed the CMODE and CUMODE commands reply arguments in the
583 protocol specification. The Channel ID is now sent in both
584 of the commands to identify the channel. Implemented this
585 new feature to the client and server. Affected files
586 lib/silcclient/command_reply.c and silcd/command.c.
588 * Made better checks for invite and ban lists in the JOIN
589 command in server. Affected file silcd/command.c.
591 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
593 * The server now performs the incoming host IP/DNS lookup
594 using the silc_socket_host_lookup and thus does not block
595 the server anymore. Affected file silcd/server.c.
597 * Completed the multi-thread support for SILC Scheduler in
598 the lib/silcutil/silcschedule.c.
600 * Fixed the configure.in.pre to detect the pthread correctly
603 * Fixed a deadlock in silc_task_queue_wakeup in the file
604 lib/silcutil/silctask.c.
606 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
608 * Added new function silc_schedule_wakeup that is used in
609 multi-threaded environment to wakeup the main thread's
610 schduler. It needs to be used when a thread adds a new task
611 or removes a task from task queues. After waking up, the
612 scheduler will detect the task queue changes. If threads
613 support is not compiled in this function has no effect.
614 Implemented the wakeup mechanism to both Unix and WIN32
615 systems. Affected files are lib/silcutil/silcschedule.[ch],
616 lib/silcutil/unix/silcunixschedule.c and the
617 lib/silcutil/win32/silcwin32schedule.c.
619 * Added new function silc_task_queue_wakeup to wakeup the
620 scheduler by the specified task queue. Affected file
621 lib/silcutil/silctask.[ch].
623 * The silc_socket_host_lookup_start now wakes up the scheduler
624 after adding the timeout task. Affected file is
625 lib/silcutil/silcsockconn.c.
627 * The silc_socket_host_lookup is synchronous now if the threads
628 support is not compiled in. However, the callback is still
629 called asyncronously through the scheduler, anyway. Affected
630 file lib/silcutil/silcsockconn.c.
632 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Added new function silc_socket_host_lookup to perform
635 asynchronous IP and FQDN lookups for the socket connection.
636 Affected files lib/silcutil/silcsockconn.[ch].
638 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Added SILC_MUTEX_DEFINE to define the mutex on environments
641 that may or may not compile the mutex support in.
643 Changed the silc_mutex_alloc interface. It allocates the
644 mutex now to the sent pointer and returns TRUE or FALSE.
646 Affected file lib/silcutil/silcmutex.h.
648 * Wrote the SILC Task Queue interface to support multi-threads.
649 Affected file lib/silcutil/silctask.[ch].
651 * Wrote the SILC Scheduler to support multi-threads. Affected
652 file lib/silcutil/silcschedule.c.
654 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Implemented the SILC Mutex API and SILC Thread API for WIN32
657 in lib/silcutil/win32/.
659 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
661 * Defined SILC Mutex API and SILC Thread API and implemented
662 them for Unix. Affected files are
663 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
664 lib/silcutil/unix/silcunixmutex.c and
665 lib/silcutil/unix/silcunixthread.c.
667 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
669 * Fixed the silc_server_remove_clients_by_server's channel
670 key re-generation. The hash table handling was incorrect
671 and would not work with many channels. Affected file is
674 * Fixed some memory leaks around the server code.
676 * Rewrote the silc_server_get_users_on_channel to support IPv6
677 based Client ID's. Affected file silcd/server.c.
679 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
680 specification. However, a separate document must be written
681 to define the detailed signing procedure and the payload
682 associated with the flag. Defined the flag to the
683 lib/silccore/silcchannel.h as well.
685 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Changed the dynamic tables to static size tables in the
688 lib/silccrypt/silchmac.c.
690 * Removed GCC dependencies from the code. A patch by cras.
692 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
694 * Do not show the error "Error receiving packet bla bla"
695 in server if it really was not an error (-2 means that reading
696 is pending). Affected file silcd/server.c.
698 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Fixed a possible crash in silc_server_remove_clients_by_server
701 in silcd/server.c. Fixed there also some memory leaks.
703 * Fixed the silc_idlist_replace_client_id. It could replace
704 wrong key in the hash table. Affected file silcd/idlist.c.
706 * Do not check whether there are global users on the channel
707 if the channel->global_users is FALSE. Affected functions
708 silc_server_remove_from_one_channel and
709 silc_server_remove_from_channels in silcd/server.c. Also,
710 do not check if the removed client is local as we can be
711 sure that global client was not removed from the channel
712 and checking for global users is not needed.
714 * The silc_server_remove_clients_by_server now re-generates
715 the channel keys correctly for those channels that had
716 clients removed from them. Affected file silcd/server.c.
718 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Found the reason of random crashes in the server. We weren't
721 ignoring the SIGPIPE signal (which can be sent in write())
722 and it crashed the server. Affected file silcd/silcd.c.
724 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Assure that sock->user_data is not NULL in the function
727 silc_server_packet_send in silcd/packet_send.c.
729 * Disconnect the remote connection if it could not be added
730 to any ID lists in the server. The affected file is
733 * Check in silc_server_packet_send[_real/dest] that the
734 socket is not disconnecting and ignore the data if it is.
735 Affected file silcd/packet_send.c.
737 * Define inline to __inline on native WIN32 compilation.
738 Affected file includes/silcwin32.h.
740 * Added some explicit type casts for inline code since MSVC
741 require them. Affected files lib/silcutil/silcbuffer.h,
742 lib/trq/silcdlist.h and lib/trq/silclist.h.
744 * Print warning in log files from now on if the packet
745 decryption fails. Affected file silcd/server.c.
747 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
749 * Changed the `say' client operation's interface to accept
750 new `type' argument to indicate the type of the message sent
751 by the library. The application may filter the library's
752 messages according the type. The affected file is the
753 lib/silcclient/silcapi.h.
755 * Added two new functions to lib/silcclient/silcapi.h:
756 silc_client_del_client and silc_client_del_client_by_id.
757 Affected file lib/silcclient/idlist.c.
759 * Moved the clientincludes.h from includes/ to silc/ and
760 serverincludes.h from includes/ to silcd/.
762 * The modes for the CMODE and CUMODE are now passed as
763 uint32 for application with COMMAND_REPLY. The affected
764 file is lib/silcclient/command_reply.c.
766 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
768 * /WHOIS without arguments shows client's own information.
769 Affected file lib/silcclient/command.c.
771 * Changed PING to not accept any arguments. The specs
772 says that client can ping only the connected server so
773 requiring an argument is not needed. Affected file is
774 lib/silcclient/command.c.
776 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
778 * Fixed a fatal bug in private message sending and reception
779 encryption and decryption when using private message keys.
780 The implementation was incorrect and did not follow the
781 specification. It causd that some of the message were
782 lost since it did not use the sending and receiving keys
783 as the protocol suggests. This has been fixed and will cause
784 incompatibilities with older clients when sending private
785 message encrypted with private message keys. Affected files
786 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
787 and various other in Irssi SILC Client.
789 Added `responder' boolean argument to the functions
790 silc_client_add_private_message_key[_ske] to indicate when
791 the key is added as responder or initiator of the key
794 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Removed the silc_ske_check_version function and created
797 a SilcSKECheckVersion callback. Added also a function
798 silc_ske_set_callbacks that is now used to set all SKE
799 callbacks. The callback functions are not given to
800 the SKE functions anymore, but this function is used to
803 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
805 * Added `silc_version' argument to the silc_client_alloc
806 to define the version of the application for the library.
807 The library will use the version string to compare it
808 against the remote host's (usually a server) version
809 string. Affected file lib/silcclient/silcapi.h
811 * Added the KE protocol context to Key Agreement context
812 in client library so that we can abort the SKE if it
813 is in process when we get timeout. Affected file is
814 lib/silcclient/client_keyagr.c.
816 * Do not resolve the client ID forever if it returns in the
817 first time that such client does not exist. This was done
818 for example with private message. Affected file is
819 lib/silcclient/client_prvmsg.c.
821 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
823 * Do not add regex.h for WIN32. The affected file
824 includes/silcincludes.h.
826 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
827 not work yet 100%. It generates the DLL's automatically
828 when compiling with --with-win32 under cygwin.
830 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
832 * lib/contrib/regex.c is not compiled on WIN32.
834 * Added silc_net_get_socket_opt function to the
835 lib/silcutil/silcnet.h.
837 * Added includes/silcwin32.h for WIN32 specific includes
840 * Do not use ptime structure or any of the posix process
841 functions on WIN32 in lib/silccrypt/silrng.c.
843 * Added silc_gettimeofday to provide generic function
844 for struct timeval on all platforms. Added the function
845 to lib/silcutil/silcutil.h.
847 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Moved the lib/silccore/silcsockconn.[ch] to the utility
850 library as they clearly belong there. As a plus side we
851 can make the actual socket connection routines platform
854 Added also new generic function silc_socket_read and
855 silc_socket_write (that used to be silc_packet_[read/write].
856 The implementation of these are platform specific.
858 * Added WIN32 specific routines of silc_socket_[read/write]
859 to lib/silcutil/win32/silcwin32sockconn.c.
861 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
863 * Added preliminary support for native WIN32 compilation under
864 cygwin (using the -mno-cygwin option for GCC) to the
865 ./configure.in.pre. The --with-win32 now prepares the
866 compilation for native WIN32.
868 * Rewrote the SILC Scheduler interface in the file
869 lib/silcutil/silcschedule.h. The scheduler is now context
870 based and does not have anymore any global static scheduler.
871 Moved the Unix scheduler to the lib/silcutil/unix/ directory
872 and created lib/silcutil/win32 directory for WIN32 based
875 * Added Unix specific network routines to the
876 lib/silcutil/unix/silcunixnet.c and the old
877 lib/silcutil/silcnet.c includes now only generic routines.
879 Added WIN32 specific network routines to the
880 lib/silcutil/win32/silcwin32net.c.
882 * Added Unix specific utility functions from the
883 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
885 * Added WIN32 SILC Scheduler to the file
886 lib/silcutil/win32/silcwin32schedule.c. The code is of course
889 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Do not handle JOIN notify in the server if the target client
892 is not registered (idata->registered == FALSE). The affected
893 file is silcd/packet_receive.c.
895 * Update the nickrec->founder in event_cumode in the Irssi SILC
896 client. Affected file irssi/src/silc/core/silc-channels.c.
898 * Fixed the CUMODE_CHANGE notify handling in the server when
899 server and router are announcing their clients on channels.
900 Now the mode changes are saved and notified correctly. The
901 affected file is /silcd/packet_receive.c.
903 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
904 They really did not replace the cache entry in the ID Cache.
905 Now they do that. Affected file silcd/idlist.c.
907 * Fixed the KICK notify handling in the Irssi SILC client to
908 update the channel records so that the kicked client does not
909 appear to be on the channel. The affected file is
910 irssi/src/silc/core/silc-channels.c.
912 * Always update the conn->current_channel when executing command
913 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
915 * Fixed the KILL notify handling in Irssi SILC client to remove
916 the killed client on all channels.
918 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * Fixed the silc_parse_command_line to remove extra spaces
921 from the start and end of the arguments. Affected file is
922 lib/silcutil/silcutil.c.
924 * Cancel and free any active protocol in the function
925 silc_server_close_connection. Affected file silcd/server.c.
927 * Cancel and free any active protocol in the function
928 silc_client_close_connction. Affected file is
929 lib/silcclient/client.c.
931 * Do not execute the KILL command for clients that are in
932 history (ie. they are not in the network). Affected file is
935 * Fixed KILL notify handling, client does not crash anymore.
936 Affected file irssi/src/silc/core/silc-channels.c.
938 * Reduced the default packet buffer size from 2048 to 1024 in
939 lib/silccore/silcpacket.c.
941 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
942 counter to the SKE context that is incresed when the SKE library
943 performs async operation outside the library. If the outside
944 process frees the SKE context and FREED status will be set
945 and the library will detect after the sync operation that the
946 libary is freed. The affected files are
947 lib/silcske/silcske[_status].[ch].
949 * Resolve the client entry information in the function
950 silc_client_channel_message to assure that NULL pointer is not
951 passed as client entry to the application. */
953 * Fixed the task timeout calculation to assure that there is
954 never negative timeouts. The affected file is
955 lib/silcutil/silcschedule.c.
957 * Fixed the channel user mode notification sending in server.
958 It was sent point-to-point to the router (or to server by router)
959 but it needs to be destined to a channel. The routines now
960 supports sending the channel user mode notifys to the channels
961 when announcing clients and channels. Affected files are
962 silcd/server.c and silcd/packet_receive.c.
964 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
965 It did not actually replace the old channel entry in the cache.
966 Affected file lib/silcclient/client_notify.c.
968 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Fixed a possible crash in silc_packet_send_prepare. It now
971 assures always that there is enough space in the buffer and
972 at the tail area of the buffer (for MAC).
974 Fixed the inbound buffer reallocation in silc_packet_read.
975 It was old code and did not handle the reallocation correctly.
978 The affected file is lib/silccore/silcpacket.c.
980 * Fixed buffer overflow in silc_parse_nickname in the file
981 lib/silcutil/silcutil.c.
983 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
985 * make install generates new server keys only if there is not
988 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
990 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
991 Added check that if the NOREPLY is set then we will not send
992 the away message. This avoids infinite loop of away messages
993 if both clients are away. The affected file is
994 lib/silcclient/client_prvmsg.c.
996 * Fixed client crash if /NICK was given without arguments.
997 Affected file lib/silcclient/command.c.
999 * Server does not send the invite list in INVITE command back
1000 to the client if the list was not altered. Added this notion
1001 to the protocol spec as well. Affected file silcd/command.c.
1003 Fixed possible crash in INVITE command by checking the
1004 value of silc_server_get_client_route command.
1006 * Fixed the INVITE notify type handling. The arguments are now
1007 taken in correct order and client does not crash. The affected
1008 file is irssi/src/silc/core/silc-channels.c.
1010 Removed the "Inviting xxx to channel" message from the
1011 client library away and let the application handle it.
1012 Affected file lib/silcclient/command.c. Added that message
1013 to Irssi SILC client's message formats.
1015 * Fixed CMODE command crash in client. It now checks the
1016 amount of arguments correctly and does not crash. The affected
1017 file is lib/silcclient/command.c.
1019 * Do not create new channel automatically in silc_channels_join
1020 but check whether the channel by that name already exists.
1021 Affected file irssi/silc/core/silc-channels.c.
1023 * Do not send the SERVER_SIGNOFF to router if the disconnected
1024 entity was the router. Affected file silcd/server.c.
1026 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1027 SILC client as it was missing from there.
1029 Added the handling of the KICK notify to the Irssi SILC client
1030 as it was missing. Added "you have been kicked" message to
1031 Irssi SILC client's message modules formats.
1033 Added the handing of the KILL notify to the Irssi SILC client
1034 as it was missing. Added the kill message module formats
1037 The affected file is irssi/src/silc/core/silc-channels.c.
1039 * The router did not save the channel mode the server announced.
1040 Affected file silcd/packet_receive.c.
1042 * Fixed a possible crash in INFO command in server. If the
1043 server did not provide the server info it crashed. Affected
1044 file silcd/command.c.
1046 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Fixed the GETKEY command in the server to check also the
1049 global list. Otherwise the GETKEY would not work correctly
1050 in normal SILC server. Affected file silcd/command.c.
1052 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Fixed GETKEY crash, it crashed if the command did not succseed.
1056 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1059 is now real and not just an macro interface to GMP.
1061 Removed the entire GMP from the source tree and imported new
1062 NSS MPI library instead. Reason for removing GMP is that it is
1063 extremely large and compiles extremely slow. The NSS MPI
1064 is only a few files and compiles in less than 10 seconds.
1065 The speed is also about the same as GMP. The MPI is imported
1066 to lib/silcmath/mpi.
1068 If the system has GMP installed we will still use the GMP.
1069 If it is not then the NSS MPI will be compiled.
1071 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Merged a long nickname (127 characters long) crash bugfix from
1074 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1076 * Merged a freed memory reference bugfix from Irssi CVS tree.
1077 Affected file irssi/src/core/commands.c.
1079 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * Added the server's public key sving and verification to the
1082 server when performing the SKE. This was missing and the
1083 remote server's (or router's) public key was accepted without
1084 checking whether we have it previously or trust it at all.
1085 Affected file silcd/protocol.c.
1087 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1089 * Check in the silc_server_timeout_remote if protocol is active
1090 and make sure that the protocol's final callback is called so
1091 that all memory if freed. Affected file silcd/server.c.
1093 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * silc_server_whois_send_reply crashed the server if the nickname
1096 was 127 characters long. Affected file silcd/command.c.
1098 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Added sanity check to the silc_server_new_client. If the hostname
1101 is provided inside username then check that the provided hostname
1102 really is the same as the resolved one. If the hostname was not
1103 resolved then check it from the public key. Affected file is
1104 silcd/packet_receive.c.
1106 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1107 if the server disconnected us and the connection is not valid
1108 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1110 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1111 the library to the lib/silcutil/silcutil.[ch].
1113 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Close log file after open. Affected file
1116 lib/silcutil/silclog.c.
1118 * Check whether sock == NULL in silc_client_send_packet and return
1119 if it is. Affected file lib/silcclient/silcclient.c.
1121 * Check rec->entry == NULL in the Irssi SILC Client before
1122 sending the channel message. Affecte file is
1123 irssi/src/silc/core/silc-servers.c.
1125 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Merged a splitted window bugfix from Irssi CVS tree. The
1128 affected file is irssi/src/fe-text/textbuffer-view.c.
1130 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1131 It did not print nickname.
1133 * Improved the distributions system a bit.
1135 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1138 irssi/src/fe-text/gui-window.c.
1140 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1141 to in-active server. The affected file is
1142 irssi/src/silc/core/client_ops.c.
1144 * Resolve the client in USERS command reply if the entry does
1145 not have username resolved. The affected file is
1146 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1147 command to WHOIS command to really resolve stuff. The USERS
1148 is not used any more in any critical section so WHOIS can
1149 be used even though it might be slower than IDENTIFY.
1151 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1154 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * Changed the protocol API a bit more consistent in the
1157 lib/silccore/silcprotocol.[ch].
1159 * Changed the following headers to ROBODoc format:
1161 lib/silccore/silcpayload.h
1162 lib/silccore/silcprotocol.h
1163 lib/silccore/silcsockconn.h
1165 All core library headers are now formatted.
1167 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Fixed a bug in Irssi SILC client; do not show that you are
1170 server/router operator if you really are not. Affected file is
1171 irssi/src/silc/core/client_ops.c.
1173 * Renamed silc_command_free_payload to silc_command_payload_free.
1174 Affected file lib/silccore/silccommand.h
1176 * Added silcmath.h to include the prototoypes of various routines
1177 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1180 * Changed the following headers to ROBODoc format:
1182 lib/silccore/silcchannel.h
1183 lib/silccore/silccommand.h
1184 lib/silccore/silcid.h
1185 lib/silccore/silcidcache.h
1186 lib/silccore/silcmode.h
1187 lib/silccore/silcnotify.h
1188 lib/silccore/silcpacket.h
1189 lib/silcmath/silcmath.h
1191 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Added checking to the server code not to start the server if
1194 ciphers and stuff are not configured properly. Affected files
1195 silcd/serverconfig.[h] and silcd/server.c.
1197 * Changed the layout of the header files of the public interfaces
1198 in the SILC libraries. The new layout supports ROBODoc
1199 documentation tool (and some others) so that it is easy to create
1200 a library reference manual. All the other headers and source
1201 code must still follow the CodingStyle document. Also source
1202 code must not include these ROBODoc stuffs, only the headers.
1203 Furthermore, all public interface headers must now be named
1204 by using `silc' prefix, example: silcapi.h, silccipher.h.
1205 Some files were renamed due to this. All the other headers
1206 must not be used as public interfaces. I will update the
1207 CodingStyle document later. Changed following headers, so far:
1209 lib/silcclient/silcapi.h
1210 lib/silccore/silcauth.h
1211 lib/silccore/silcprivate.h
1212 lib/silccrypt/silcdh.h
1214 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Removed silc_client_packet_send_flush from the client library
1219 as it is not needed. Affected file lib/silcclient/client.[ch].
1221 * Added printing of message of unresolved authentication method
1222 to the Irssi SILC client. Added it to the module formats.
1223 Removed the same message from the client library.
1225 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1227 * Added new distribution feature, DISTLABEL. Every distribution
1228 can define own preprocessor label that can be used in the
1229 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1230 file distributions, acconfig.h.pre and prepare.
1232 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Added Makefile.defines_int to include the actual definitions
1235 for Makefile.defines.in. Tested the new distribution system,
1236 created distributions and tested installation.
1238 * Added AWAY message printing to the Irssi SILC client. Added
1239 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1241 * Added SCONNECT command to call the SILC's CONNECT command.
1242 Cannot use CONNECT directly since Irssi uses that internally.
1243 Affected file irssi/src/silc/core/silc-servers.c.
1245 Added ACTION local command. It is same as ME command but takes
1246 the channel as mandatory argument.
1248 Rewrote some of the Irssi's help files to suite for SILC
1251 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * Added Makefile.defines[.in] that should for now on be included
1254 in all Makefile.am file in the source tree. That file includes
1255 all common compilation definitions for SILC source tree.
1257 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Minor changes to the ./prepare script to change the package
1260 name according the distribution name to the configure.in.
1262 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Created new distribution system. Added file `distributions'
1265 that defines all the distributions that can be created out of
1266 the SILC source tree. The ./prepare script now reads that
1267 file to determine how to prepare the distributions. The
1268 first argument to the ./prepare is the name of the distribution
1269 and second is the version of the distribution. If given
1270 without arguments it creates the default (toolkit) distribution
1271 with the default version (defined in ./prepare).
1273 All Makefile.am files that are subject to the distributions
1274 are now named as Makefile.am.pre. These are ./Makefile.am
1275 and lib/Makefile.am. Others may be changed later.
1277 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1279 * Added invite list, ban list, some key management and connection
1280 error message printing to module formats in the Irssi SILC client.
1282 * Added new silc_client_set_away_message to set the away message
1283 that is back to the person who sent private message. The
1284 affected file lib/silcclient/silcapi.h and the
1285 lib/silcclient/client_prvmsg.c.
1287 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1289 * Fixed the private message sending in the Irssi SILC client,
1290 added local command KEY to the Irssi SILC client.
1292 Added key management and key agreement message formats to the
1293 irssi/src/fe-common/silc/module-formats.[ch].
1295 Added USERS (alias WHO) printing, server/router operator
1296 indication and LIST command printing to the module formats.
1298 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * Fixed channel joining notify handling, cumode notify handling
1301 from Irssi SILC client.
1303 * Added SILC specific module-formats to the Irssi SILC client so
1304 that SILC specific message hilighting, colors etc is possible.
1305 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1307 Added channel mode, channel user mode, actions, notices,
1308 whois and whowas printing to the the module-formats.c.
1310 * Fixed a bug in channel deletion in the server. The channel
1311 is not left to the cache even if the channel founder auth mode
1312 is set when there are no users anymore on the channel. Affected
1313 file silcd/server.c.
1315 * The silc_net_localhost now resolves the entire hostname including
1316 the domain name. Affected file lib/silcutil/silcnet.c.
1318 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Changed the ask_passphrase client operation to be ascynchronous.
1321 It has now a completion callback and a context that the
1322 application must call after it has got the passphrase from
1323 the user. Affected files lib/silcclient/silcapi.h,
1324 lib/silcclient/protocol.c, lib/silcclient/command.c and
1327 Added SilcAskPassphrase callback that the application calls
1328 to deliver the passphrase to the library.
1330 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1331 The public key verification and especially a certificate
1332 verification is asynchronous procedure.
1334 Added new SILC_SKE_STATUS_PENDING status to indicate the
1335 request is pending and a callback will be called to finalize
1338 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1339 indicate that remote end did not send its public key (or
1340 certificate), even though we require it. Added check for this
1341 condition in the SKE. This was a security bug, now fixed.
1343 Defined new SilcSKEVerifyCbCompletion callback that is called
1344 when the verification process is completed.
1346 The affected files lib/silcske/silcske_status.h and
1347 lib/silcske/silcske.[ch].
1349 * Changed the verify_public_key client operation to be async
1350 as well. Defined SilcVerifyPublicKey callback that is used to
1351 indicate the success of the public key verification process.
1353 Changed the server and client to use the new async client
1356 * Changed the Irssi SILC client's internal scheduler to be called
1357 twice as many times as it used to be. As a result the client
1358 should be a bit faster now. Affected file is
1359 irssi/src/silc/core/silc-core.c.
1361 * Added support to Irssi SILC client of asynchronous public key
1362 verification and passphrase inquiry. Affected file is
1363 irssi/src/silc/core/silc-core.c.
1365 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Do not say "You have left channel %s" in client library.
1368 Moved it to the application. Affected files are
1369 lib/silcclient/command.c and silc/client_ops.c.
1371 * Fixed silc_client_get_clients. Command context was not
1372 duplicated and was freed memory in the callback. Affected
1373 file lib/silcclient/idlist.c.
1375 * Do not say "you are now talking..." on JOIN command in the
1376 client library. The appliation must handle it.
1378 * Do not say ".. changed topic to" in command reply in the
1379 client libary. The application must handle it.
1381 * Fixed TOPIC command sending in the client library.
1383 * Fixed a memory leak in silc_client_command_free in the file
1384 lib/silcclient/command.c.
1386 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Imported a modified version of Irssi client to the source tree.
1389 The Irssi will be used to create a new client called
1390 Irssi SILC. Imported to irssi/.
1392 Added silc_core_init_finish function to the Irssi. Affected
1393 file irssi/configure.in.
1395 A lot changes in the Makefile.ams around the irssi tree.
1397 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1399 * Do not rehash if the new size is same as the old size of the
1400 hash table, in the silc_hash_table_rehash*. The affected file
1401 lib/silcutil/silchashtable.c.
1403 * Replaced hash_table_del_by_context calls from the server
1404 (when channel->user_list and client->channels) to the
1405 hash_table_del as it is sufficient and faster.
1407 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Added silc_hash_table_list, silc_hash_table_get and the
1410 SilcHashTableList structure to provide an alternative way to
1411 traverse the hash table. The affected files are
1412 lib/silcutil/silchashtable.[ch].
1414 * Changed the server's idlist routines to use the hash table
1415 routines to optimize the code.
1417 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Replaced the client entry's `channel' list and channel entry's
1420 `user_list' list to hash tables for optimized lookup. Changed
1421 the code to use the hash table interface around the code.
1422 Affected file lib/silcd/idlist.[ch].
1424 * Added `auto_rehash' boolean argument to the function
1425 silc_hash_table_alloc to indicate whether the hash table should
1426 auto-rehash when it thinks is appropriate time. It will
1427 increase the hash table size if the there is twice as much
1428 entries in the table than the size of the table, and will
1429 decrease the size if there are twice as less entries than
1430 the size of the table.
1432 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1434 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1436 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * silc_idcache_purge_by_context deletes the entry now by context
1439 as it is supposed to do. Affected file lib/silccore/idcache.c.
1441 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1442 client is not anymore valid (WHOWAS givens the info) and not
1443 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1445 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Removed the `data' and `data_len' arguments from the ID Cache
1448 interfaces and added `name' argument. ID Cache does not handle
1449 anymore the binary data only a names associated with given ID.
1451 * When hashing a Client ID with silc_hash_id the entire ID is
1452 not hashed anymore, instead only the hash of the Client ID is
1453 hashed. This way we can access the Client ID from the cache
1454 with Client ID but with the hash of the ID (which is a hash of
1455 the nickname) as well without any difference in performance.
1457 Added also silc_idcache_find_by_id_one_ext to do one on one
1458 searching when we have the actual ID. Added also function
1459 silc_hash_client_id_compare. The affected files are
1460 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1462 * When hashing the name associated with a ID it is always done
1463 in lowercase. This way we can access the cache without worrying
1464 about case-sensitivity, even though, for example nicknames are
1467 * Fixed a bug in server with channel message sending. It put
1468 wrong ID type as destination ID. The affected file
1469 silcd/packet_send.c.
1471 * silc_idcache_del_by_context now deletes from all hash tables
1472 by context. Affected file lib/silccore/idcache.c.
1474 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Changed the client library to use the new ID Cache interface.
1477 Changes around the source tree.
1479 * Added silc_hash_table_rehash_ext to rehash with specific
1480 hash function. Affected file lib/silcutil/silchashtable.[ch].
1482 * Added silc_hash_string_compare to compare two strings in the
1483 hash table. Affected file lib/silcutil/silcutil.[ch].
1485 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1487 * Added new function silc_idcache_del_by_context into the
1488 lib/silccore/idcache.[ch].
1490 * Changed the server's ID list routines to use the new ID Cache
1491 interface. Changes around the source tree.
1493 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1495 * Added silc_hash_table_del[_by_context]_ext functions in to the
1496 lib/silcutil/silchashtable.[ch].
1498 Removed silc_hash_table_find_all* routines and added new
1499 silc_hash_table_find_foreach to replace them.
1501 Added silc_hash_table_replace_ext function as extended
1502 replacing function. Separated the simple hash table interface
1503 from the extended hash table interface in the file
1504 lib/silcutil/silchashtable.h.
1506 * Fixed minor bugs and changed it to use some of the new
1507 hash table functions in lib/silccore/idcache.c
1509 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1511 * Added new function silc_hash_table_find_all to return all keys
1512 in the hash table by the specified key. As the hash table is
1513 collision resistant it also makes it possible to have several
1514 duplicate keys in the hash table. This function may be used to
1515 find all of the keys from the hash.
1517 Added user_context arguments to the SilcHashFunction,
1518 SilcHashCompare and SilcHashDestructor to deliver user specified
1521 Added new fuctions silc_hash_table_find[_all]_ext to do
1522 extended lookup with specified hash and compare functions and
1523 specified user contexts.
1525 Added new function silc_hash_table_add_ext to add the key
1526 with specified hash function and user context.
1528 Added new function silc_hash_table_foreach to traverse all
1529 entrys in the hash table. Added SilcHashForeach callback
1532 Added new function silc_hash_table_del_by_context to delete
1533 the entry only if the context associated with the key matches.
1535 Affected files are lib/silcutil/silchashtable.[ch].
1537 * Removed silc_hash_[server/client/channel]_id and added just
1538 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1539 silc_hash_id_compare to compare two ID's using as the hash table
1540 comparison function. Added also silc_hash_data to hash
1541 binary data and silc_hash_data_compare to compare it.
1543 * Removed silc_idlist_find_client_by_hash as it is not needed
1544 anymore. Affected file silcd/idlist.[ch].
1546 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1547 to use internally the SilcHashTable. The new ID Cache is a lot
1548 faster than the old one. Some of the ID Cache interface was also
1549 rewritten and obsolete and stupid functions were removed.
1551 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Added entry_count field to the SilcHashTable to keep the number
1554 of the entries in the table. Implemented the function
1555 silc_hash_table_rehash. Added new function
1556 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1558 Fixed a minor bug in silc_hash_table_free.
1560 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1561 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1562 into the lib/silcutil/silcutil.[ch].
1564 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Implemented a collision resistant hash table into the
1567 lib/silcutil/silchashtable[ch]. See the header and the source
1568 for the SilcHashTable API.
1570 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1572 * Merged dotconf version 1.0.2 into lib/dotconf.
1574 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Do not compile anything in lib/silcsim/* if the SIM support
1577 is not enabled. The tree should now compile without problems
1580 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Compiled the SILC under cygwin. Compiled and tested briefly
1583 without problems. More tests needed. The SIMs didn't compile
1586 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1588 * Fixed possible crash in silc_get_username in the
1589 lib/silcutil/silcutil.c.
1591 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Fixed a va_arg in silc/client_ops.c.
1595 * Oops, RC5 routines were named AES and caused some problems
1596 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1598 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Added new SilcIDIP structure into the lib/silccore/id.h and
1601 replaced the old `ip' fields from all SILC ID's to that type.
1602 This is a step towards IPv6 support.
1604 The silc_id_get_len takes now the ID as an extra argument.
1605 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1606 both IPv4 and IPv6 based ID's.
1608 The affected files are lib/silccore/id.[ch] and other files
1609 around the tree using these routines.
1611 * Removed the ID length arguments in server from various
1612 silc_server_send_notify_* routines -> they are not needed
1615 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Fixed memory leak in silc_encode_pem_file in the file
1618 lib/silcutil/silcutil.c.
1620 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Check minor version as well in the SKE. Affected files are
1623 silcd/protocol.c and lib/silcclient/protocol.c.
1625 * Added --identifier option to the server so that an identifier
1626 can be when creating the public key for the server. Affected
1627 file is silcd/silcd.c.
1629 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1630 lib/silccrypt/silcpkcs.c.
1632 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Register default ciphers and stuff when using -C option with
1635 the server. Affected file sildc/silcd.c.
1637 * Put back the servers public key filename format, it is better
1638 than the new one. For now, the client keys are saved with the
1639 new filename format. The affected file silc/client_ops.c.
1641 * Implemented the Cipher API for the rest of the ciphers that
1642 did not implement it or implemented it the wrong way.
1644 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Register default ciphers and stuff when using the -S option
1647 in the client. Affected file silc/silc.c. Same also when
1648 creating new key pair with -C option.
1650 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Fixed the silc_verify_public_key client operation function to
1653 save the public keys differently. The fingerprint is now
1654 used as filename and not the hostname. This way also the
1655 client keys are saved uniquely and not with hostnames. The
1656 affected file is silc/client_ops.c.
1658 * Trimmed the silc_hash_fingerprint function to remove extra
1659 whitespaces from the end of the fingerprint. The affected
1660 file is lib/silccrypt/silchash.c.
1664 * Added silc_cipher_register_default function to register all
1665 default ciphers. It can be used when configuration files
1666 does not exist and the application does not want any specific
1667 ciphers in any specific order.
1669 The SilcDList is now used as silc_cipher_list dynamically
1670 allocated cipher list. Removed the static list all together
1671 and now all ciphers must be allocated to the dynamic list.
1672 The silc_cipher_alloc routine was changed to check only the
1675 All silc_cipher_* routines that used to return int returns
1678 The affected files lib/silccrypt/silccrypt.[ch].
1680 * The same thing was done to silc_hash_* as for silc_cipher_*
1681 routines. Affected files lib/silccrypt/silchash.[ch].
1683 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1684 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1685 Added also silc_pkcs_[un]register[_default] functions.
1686 Removed the data_context from the PKCS API.
1688 * Added silc_hmac_register_default function to register default
1689 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1690 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1691 to unregister all hmacs at once.
1693 * Register the default ciphers, hash functions, PKCSs and HMACs
1694 if client's configuration file does not exist. The affected
1697 * The client did not load the hash functions from the SIM
1698 modules at all. Added support for this. Affected file is
1699 silc/clientconfig.c.
1701 * When decoding public key with silc_pkcs_public_key_decode, check
1702 the supported algorithm only if PKCS are registered. Affected
1703 file lib/silccrypt/silcpkcs.c. The same was done with the
1704 silc_pkcs_private_key_decode.
1706 * Fixed the SILC List routines to keep the list always in order.
1707 It used to change the list's order when traversing the list but
1708 not it preserves the order. Affected file lib/trq/silclist.h.
1710 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Added the client library to use the SilcSocketConnection's
1713 reference counter (by silc_socket_dup) to prevent the bug that
1714 the socket object may be freed underneath async operation.
1716 * The name resolv library checking fixes in the configure.in.pre.
1719 * Created new version of the protocol drafts for future
1720 development. The -03 drafts are the ones that will be changed
1721 in the trunk now and the -02 will remain as they are.
1723 * Send list of CUMODE notifys to the router when announcing
1724 the channel users to the router. Affected file silcd/server.c.
1725 If the router receiving channel founder CUMODE for a channel
1726 that already has channel founder it will send CUMODE notify
1727 to the sender to remove the channel founder rights from the
1728 announced client. Affected file silcd/packet_receive.c.
1730 * The CUMODE notify may now use Server ID as well as the entity
1731 who changes the mode. Updated protocool specs.
1733 * Updated INSTALL and README files.
1735 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * New web pages in the http://silc.pspt.fi. The pages was
1742 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1744 * Implemented the [DenyConnectin] config section in the server.
1745 Added silc_server_config_denied_conn to check whether incoming
1746 connection is denied. Affected file silcd/serverconfig.[ch].
1748 * Do not check the ports when checking the incoming configuration
1749 data if the port is 0, meaning any. Affected file is
1750 silcd/serverconfig.c.
1752 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Fixed buffer overflow in silc_string_compare in the file
1755 lib/silcutil/silcutil.c.
1757 * Fixed double free in silc_server_command_leave in the file
1760 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Fixed the version checking in the server. Affected file is
1765 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Fixed the configuration data fetching when accepting new
1768 connections in the server. Affected file silcd/server.c.
1770 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Added `sender_entry' argument to the function
1773 silc_server_packet_relay_to_channel so that we can check
1774 whether some destination actually belongs to the same route
1775 the sender belongs (ie, we must not resend the packet to the
1776 sender). Affected file silcd/packet_send.[ch].
1778 * Added `servername' field to the SilcClientEntry in the server
1779 to hold the name of the server where client is from. Affected
1780 file is silcd/idlist.h.
1782 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Moved the channel message encrypting in the router betwen
1785 router connections from silc_server_channel_message to the
1786 silc_server_packet_relay_to_channel since we want to check
1787 whether we have anybody channel before encrypting anything.
1788 Affected files silcd/packet_[receive/send].c.
1790 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Fixed the [AdminConnection] server config section to support
1793 multiple entries. Affected file silcd/serverconfig.c.
1795 * Added support into the server to check the validity of the
1796 incoming connection before executing any KE or authentication
1799 * The connection configuration is now saved to the KE and
1800 connection auth protocol contexts and not fetched anymore in
1801 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1803 * The local hosts listenning address and port is also resolved
1804 now when starting the server. We want to have the socket object
1805 to include the real address and port for the listener. Added
1806 new function silc_net_check_local_by_sock into the files
1807 lib/silcutil/silcnet.[ch].
1809 * Fixed a broadcast bug in server -> do not broadcast if we
1812 * Fixed a routing bug. Do not route broadcast packets ever.
1813 Broadcast packets must be processed always and not routed since
1814 they may be destined to some other host than yourself and thus
1815 would get routed without no good reason. Affected file is
1818 * Added function silc_server_config_is_primary_route to check
1819 whether primary router connection has been configured (a router
1820 configuration that we are initiating). If there is not, we
1821 will assume that there is only two routers in the SILC network
1822 and we will use the incoming router connection as our primary
1823 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1825 * Changed the order of the broadcasting. Broadcast _after_ the
1826 packet has been processed not before. Affected file is
1829 * Fixed a [ClientConnection] parsing bug. The port was never
1830 parsed correctly thus resulting to port 0. Affected file
1831 silcd/serverconfig.c.
1833 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1834 argument and did not set the broadcast packet flag. Affected
1835 file silcd/packet_send.c. Fixed same bug in the function
1836 silc_server_send_notify as well.
1838 * If we receive NEW_ID packet for our own ID in the server, ignore
1841 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Removed the nickname from the Private Message Payload.
1846 Updated the code and the protocol specs.
1848 * Updated protocol specs for submitting to the IETF.
1850 * Tweaked the Random Number Generator a bit. Affected file
1851 lib/silccrypt/silcrng.c. Exported a new function
1852 silc_rng_[global]_add_noise which can be used to add more
1855 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Do not parse packets with different timeout when protocol
1858 is active -> may cause problem with rekey. Affected file
1861 * When server receives signoff notify it must not create
1862 new channel key if the client is on any channels since the
1863 sender of the signoff notify will create it.
1865 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Added printing of error messages during SKE protocol from the
1868 failure packet sent by server during SKE. Affected file
1871 * Removed the client's failure_callback handling with timeout
1872 and handle it immediately when received.
1874 * The SKE library returned wrong type in SUCCESS and FAILURE
1875 packets. They must be 32 bit MSB not 16 bit MSB.
1877 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Ok, rewrote the logic of the re-key and now it seems to work.
1880 I tested it on high traffic with frequent re-keys without
1881 problems. Added hmac_receive (and renamed hmac to hmac_send)
1882 in SilcClientConnection in lib/silcclient/client.h and
1883 in SilcIDListData in silcd/idlist.h. Also, removed the
1884 SilcPacketParserContext's cipher and hmac fields as they are
1885 not needed anymore and actually caused some problems when
1886 the ciphers and hmac's changed underneath the packet parser.
1888 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * If re-key protocol is active then process the incoming packets
1891 synchronously since we must assure that icoming packets encrypted
1892 with the old key is processed before the new keys is set to
1893 use. This is true other packets than for REKEY packets.
1894 Affected file silcd/server.c. The same was done to client library
1895 as well, affected file lib/silcclient/client.c.
1897 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Fixed bug in client and server to accept the force send if
1900 the packet is send from silc_[server/client]_packet_process
1901 function. Otherwise the packets are never delivered, oops.
1903 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Disable force sending of packets when REKEY protocol is active.
1906 We must assure that no packet is sent directly when rekey is
1907 performed. All packets must be sent through packet queue.
1908 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1909 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1910 function is silc_[server/client]_packet_send_real to check
1913 * Replaced the SIM paths from example config files to
1914 /usr/local/modules. Also, make install creates now
1915 /usr/local/silc/logs directory to hold all the SILC server
1918 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Made the configure.in.pre work on Solaris. Patch by salo.
1922 * Made all ciphers compatible with non-x86 machines. Defined
1923 CBC mode macros into lib/silccrypt/ciphers_def.h.
1925 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * Fixed the make install.
1929 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1931 * When MAC computation fails the silc_packet_decrypt returned 0
1932 even though it was supposed to return -1. Fixed this. The
1933 affected file is lib/silccore/silcpacket.c.
1935 * Do not replace the config files in /etc/silc (in make install)
1936 if they already exist. Affected file ./Makefile.am.
1938 * Do not send re-key packets immediately but through packet queue.
1939 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1941 * Changed silc_net_check_host_by_sock to return FALSE if the
1942 IP/DNS could not be resolved. Though, it returns the IP address
1943 now even if it could not resolve it (but returns also FALSE).
1944 Affected file lib/silcutil/silcnet.[ch].
1946 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1948 * Added silc_pkcs_decode_identifier to decode the public key's
1949 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1950 Added also silc_pkcs_free_identifier. Added also new context
1951 SilcPublicKeyIdentifier.
1953 * Added -S option to the silc client. It is used to dump the
1954 contents of the specified public key file.
1956 * Changed the PKCS api to return the public key length when
1957 setting the public key.
1959 * Fixed a fatal bug in the public and private key file loading.
1960 Affected file lib/silccrypt/silcpkcs.c.
1962 * Execute the packet parsing for client with zero (0) timeout
1963 if the protocol is active. Affected file silcd/server.c.
1965 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Made the key generation options to the silcd program. Added
1968 -C option, equivalent to client's option.
1970 * Added new [ServerKeys] config section to the server. It
1971 configures the server's public and private key.
1973 * Defined generic Public Key Payload into the protocol
1974 specification to send specific type of public keys and
1977 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1978 public key or certificate.
1980 * Implemented the GETKEY command to the server and to the
1981 client library and on user interface.
1983 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Made preliminary `make install' work.
1987 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Added SilcServerRekey context into silcd/idlist.h.
1991 * Added the PFS support as defined in the specification to the
1992 SKE protocol. Affected files lib/silcske/*.c.
1994 * Added `ske_group' field to the SilcServerRekey context to hold
1995 the number of the SKE group that is used with PFS in re-key.
1996 Affected file silcd/idlist.h.
1998 * Added PFS re-key support to the server. Affected file is
2001 * Added silc_protocol_cancel to cancel execution of the next
2002 state of the protocol. Affected file is
2003 lib/silccore/silcprotocol.[ch].
2005 * Added the re-key support with and without PFS to the client
2006 library. Re-key is performed once in an hour, by default.
2008 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2009 Added silc_client_rekey_callback and silc_client_rekey_final.
2010 Affected files are lib/silcclient/protocol.[ch] and
2011 lib/silcclient/client.[ch].
2013 * Removed the `hmac_key' and `hmac_key_len' fields from the
2014 SilcClientConnection structure; not needed. Affected file is
2015 lib/silcclient/client.h.
2019 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Do not ask whether user wants to use the negotiated private key
2022 for private messages, just use it. Affected file is
2023 silc/local_command.c.
2025 * Added `send_enc_key' and `enc_key_len' fields to the
2026 SilcIDListData structure since they are needed in the re-key
2027 phase. Affected file is silcd/idlist.[ch].
2029 * Implemented the simple re-key protocol into the server.
2030 Affected files silcd/server.c and silcd/protocol.[ch]. The
2031 re-key will be performed once in an hour, by default.
2033 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2034 Added silc_server_rekey, silc_server_rekey_callback and
2035 silc_server_rekey_final.
2037 * Removed Tunneled flag from the protocol. Updated the code
2038 and the specifications.
2040 * Adde `pfs' field to the SilcIDListData to indicate whether
2041 the PFS is to be performed in the re-key. Affected file is
2044 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2047 int64 of at least the xintXX size. If void * is less that 4
2048 bytes uint32 * will be used. Defined bool as boolean.
2050 * Changed _ALL_ unsigned long and unsigned int to uint32,
2051 unsgined short to uint16 in the source tree.
2053 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2054 not handle clients that has entry->data.registered == FALSE.
2055 They are not in the network anymore. Affected file is
2058 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Implemented the sending of the SERVER_SIGNOFF notify in the
2061 server. Affected file is silcd/server.c.
2063 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2064 Added also silc_notify_payload_encode_args into the
2065 lib/silccore/silcnotify.[ch].
2067 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2068 Affected file silcd/packet_receive.c.
2070 * Implemented the SERVER_SIGNOFF notify handling in the client
2071 library. Affected file lib/silcclient/client_notify.c. Also,
2072 implemnted the printing of the SERVER_SIGNOFF info to the
2073 application. Affected file silc/client_ops.c.
2075 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2076 if the deleting was successful. Affected file silcd/idlist.[ch].
2078 * Added support for public key authentication in the connection
2079 authentication protocol in the client library. Affected file
2080 lib/silcclient/protocol.c.
2082 * Changed the server's silc_idlist_get_clients_by_* interface
2083 to support already allocated array so that new entries may be
2084 added to pre-allocated array. Affected file silcd/idlist.[ch].
2085 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2086 and command replies.
2088 * All command reply functions in the server now calls the
2089 pending command callback even if error occured. This way the
2090 error will be delivered to the client as well. Affected files
2091 silcd/command.c and silcd/command_reply.c.
2093 * Fixed INFO command to return local server's info if no server
2094 was provided. Affected file lib/silcclient/command.c.
2096 * Removed RESTART command for good. Updated the code and the
2099 * Rewrote parts of the task system. It is a bit simpler now.
2100 Removed unsued task priorities. The affected files are
2101 lib/silcutil/silctask.[ch].
2103 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * Moved the USERS printing from the library to the application.
2106 Affected files lib/silcclient/command.c and silc/client_ops.c.
2108 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added channel key re-key support. The re-key is perfomed
2113 only by the router and is done once in an hour. Added `rekey'
2114 field to the SilcChannelEntry in the server. Affected files
2115 silcd/server.c and silcd/idlist.h.
2117 * Added silc_task_unregister_by_context into the file
2118 lib/silcutil/silctask.[ch].
2120 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Added SILC_UMODE_GONE mode to indicate when the client is not
2123 present in the SILC network. Added also support to the local
2124 command AWAY that will set this mode. Added support of showing
2125 "xxx is gone" in WHOIS command. The USERS command shows the
2126 gone status as well.
2128 * Fixed setting server and router operator privileges in the
2129 server's UMODE command. Affected file silcd/command.c.
2131 * Merged the SKE KE1 and KE2 payloads into one payload. The
2132 new KE payload is equivalent to the old KE2 payload.
2134 Cleaned up the SKE Start Payload parsing. It now uses the
2135 simple buffer unformatting to do the parsing. A lot faster
2138 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2139 to the SKE that is used to indicate whether both of the SKE
2140 parties should perform authentication. By default only the
2141 responder performs authentication. By setting this flag also
2142 the initiator must do authentication. By default it is unset
2143 since in normal SKE case, client to server connection, only
2144 the responder should do authentication. When doing SKE between
2145 two clients both should perform authentication. Updated the
2146 code and the protocol specs.
2148 * A little fix to IDENTIFY command in the server. Search the
2149 client first by hash not nickname. Affected file is
2152 * Fixed the silc_client_close_connection to support closing
2153 the client to client connections wihtout deleting too much
2154 data. Affected file lib/silcclient/client.c.
2156 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2157 are received if protocol used to be active but is not anymore
2158 the application would crash due to NULL pointer dereference.
2159 Affected files silcd/server.c and lib/silcclient/client.c.
2161 * Added `hash' field to the SilcClientConnection to include
2162 the hash function negotiated in the SKE protocol.
2164 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2165 to set the channel founder authentication data. A client can
2166 claim the founder rights later by providing the authentication
2167 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2168 This way the channel founder can regain the channel founder
2169 privileges even it is left the channel. This works only on
2170 local server and the client must be connected to the same
2171 server to be able to regain the founder rights. Updated the
2172 protocol specs accordingly.
2174 Added support to the CMODE command in the client to set the
2175 founder auth data. Read the README to see how to set it.
2177 Added support to the CUMODE command to claim the founder
2178 rights. Read the README to see how to do it.
2180 Added support for the founder authentication to the Channel
2181 Entry in the server. Affected file silcd/idlist.h.
2183 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2184 server's CMODE command. Affected file silcd/command.c.
2186 * Added the following new functions into lib/silccore/silcauth.[ch]:
2187 silc_auth_get_method and silc_auth_get_data.
2189 * The server now saves the remote hosts public key to the
2190 SilcIDListData pointer. Affected file silcd/protocol.c.
2192 * The normal server now does not remove the channel entry from
2193 the cache if the founder authentication data is set. It used
2194 to remove it if the founder was the last one on the channel on
2195 the server and left the channel. The auth data is saved and
2196 if the channel is re-joined later the old entry is used with
2197 the old auth data. Affected files silcd/command_reply.c and
2200 * Removed the `pkcs' field from the SilcIDListData structure
2201 in the server; it is not used. Affected file silcd/idlist.h.
2203 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Fixed packet processing on slow links. Partial packets were
2206 never re-processed because the incoming data buffer was cleared
2207 by the application. Application must not directly clear the
2208 sock->inbuf, the packet processing routines handle it. Fixed
2209 this in client library and in server.
2211 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Fixed the WHOIS and IDENTIFY send reply function to really
2214 check whether to send list or just one entry. Affected file
2217 * Cleaned up the LEAVE command's channel key distribution. The
2218 affected file silcd/command.c.
2220 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2221 can enforce the channel mode as well. In that case the ID
2222 includes the ID of the server. The code now enforces the
2223 mode change if the router have different mode than the server.
2225 * The notify client operation with CMODE_CHANGE notify can now
2226 return NULL client_entry pointer if the CMODE was not changed
2227 by client. Application must check for this.
2229 * Added <Server ID> argument to INFO command to support server
2230 info fetching by Server ID.
2232 * Added silc_server_announce_get_channel_users to get assembled
2233 packets of channel users of the specified channel. Affected
2234 file silcd/server.[ch].
2236 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2237 was freed underneath the ID Cache.
2239 * Re-announce clients when the server received CHANNEL_CHANGE
2240 notify from the router. Affected file silcd/packet_send.c.
2242 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2245 crashed since it did not handle the fact that there is no cipher
2246 called "3" and didn't check the error condition. Now fixed.
2248 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2249 flag. It can be used to send message requests.
2251 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Implemented the RESTART command in the client.
2255 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2256 notice type messages. Added notice printing to the user
2259 * The channel keys are not re-generated if the channel's mode
2260 is PRIVKEY, ie private key on the channel exists. Affected
2261 files silcd/server.c and silcd/command.c.
2263 * Fixed a little bug in channel message delivery when channel
2264 private keys are set in the server. Affected file is
2265 silcd/packet_send.c.
2267 * Changed the setting on channel->on_channel = TRUE from the
2268 silc_client_save_channel_key to the JOIN command reply. The
2269 key payload is not received if the private channel key is set.
2270 Affected file lib/silcclient/command_reply.c and the
2271 lib/silcclient/client_channel.c.
2273 * When the CMODE_CHANGE notify is sent and the channel private
2274 key mode is removed the channel key must be re-generated in
2275 other cells as well. Added this support for the router in the
2276 silcd/packet_receive.c.
2278 * Added new local command NOTICE to send notice message on
2279 channel. Affected file silc/local_command.[ch].
2281 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added new local command ME to the client. It is used to send
2284 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2285 some action. Affected file silc/local_command.[ch].
2287 * Changed channel_message and private_message client operations
2288 to deliver the message flags to the application. Added also
2289 the `flags' arguments to the silc_client_send_channel_message
2290 and silc_client_send_private_message functions. Affected file
2293 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Redefined the Private Message Payload to support private message
2296 keys and to support the new private message flags. Updated
2297 the protocol specs. Flags makes it possible to have for example
2298 CTCP style messages.
2300 * Added new type SilcPrivateMessagePayload and defined an API
2301 for it in the lib/silcclient/silcprivate.[ch].
2303 * Tested private message private keys successfully. Tested the
2304 private message key set, unset and list commands with the new
2307 * Redefined the Channel Message Payload to include the channel
2308 message flags (equal with private message flags) to support
2309 for example CTCP style messages.
2311 * Defined some of the message (for channel and private message)
2312 flags. Updated the protocol specs and added the flags to the
2313 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2315 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Added SilcKeyAgreementStatus type to the key agreement routines
2318 to indicate the current status and error if one occured.
2319 The status types are defined in the lib/silcclient/silcapi.h.
2321 * Added new local command KEY that is used to set and unset private
2322 keys for channels, set and unset private keys for private messages
2323 with remote clients and to send key agreement requests and
2324 negotiate the key agreement protocol with remote client. The
2325 key agreement is supported only to negotiate private message keys,
2326 it currently cannot be used to negotiate private keys for channels,
2327 as it is not convenient for that purpose.
2329 * Fixed a minor pending callback setting bug in the function
2330 silc_client_get_client_by_id_resolve, now the function works.
2331 Affected file lib/silcclient/idlist.c.
2333 * Added function silc_net_get_local_port to get local bound
2334 port by socket. Added to lib/silcutil/silcnet.[ch].
2336 * Added `sockets' and `sockets_count' fields to the SilcClient
2337 object. They hold the sockets of the listenning sockets in
2338 the client. Listenning sockets may be for example the key
2339 agreement server. Affected file lib/silcclient/client.[ch].
2340 Added functions the silc_client_add_socket and the
2341 silc_client_del_socket. They are exported to the application
2344 * Added ~./silc/clientkeys to support other client's public keys.
2346 * Renamed verify_server_key client operation to verify_public_key
2347 and added one argument to indicate the type of the connection
2348 (server, client etc.).
2350 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Added silc_server_connection_auth_request to handle the
2353 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2354 silcd/packet_receive.[ch].
2356 * Added silc_server_send_connection_auth_request into the
2357 silcd/packet_send.c to send the connection auth request packet.
2359 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2362 * Fixed the public key authentication in responder side in the
2363 server. The `auth_data' pointer includes the SilcPublicKey
2364 not the path to the public key. Affected file silcd/protocol.c.
2366 * Implemented the public key authentication in the initiator side
2367 in the server. Affected file silcd/protocol.c.
2369 * Removed the [RedirectClient] config section from the server
2370 configuration. Is not needed and I don't want to implement it.
2372 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Cleaned up the CMODE command in the server. It now works
2375 correctly and supports all the modes defined in the protocol.
2376 Affected file is silcd/command.c.
2378 * Added `hmac_name' field to the SilcChannelEntry in the server
2379 to hold the default HMAC of the channel. It can be set when
2380 creating the channel (with JOIN command). Affected files
2383 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2384 type to indicate the change of the current cipher and hmac
2385 on the channel. Client can safely ignore the <cipher> argument
2386 (if it chooses to do so) since the CHANNEL_KEY packet will
2387 force the channel key change anyway. The <hmac> argument is
2388 important since the client is responsible of setting the new
2389 HMAC and the hmac key into use.
2391 * Fixed the CMODE command in the client library as well.
2393 * Tested CMODE command in router environment successfully.
2395 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Show the version of the remote client (or server) when connecting
2398 to the server. It is logged to the log file. Affected file
2399 is silcd/protocol.c.
2401 * Fixed the KILLED notify handling in the client library. The
2402 client must be removed from all channels when receiving the
2405 Also, do not remove the client entry when giving the KILL
2406 command but when the KILLED notify is received.
2408 * Removed silc_idlist_find_client_by_nickname from the server.
2409 Not needed anymore. Affected files silcd/idlist.[ch].
2411 * Implemented the CHANNEL_CHANGE notify type handling to the
2412 server. Affected file silcd/server.c.
2416 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Added silc_server_send_notify_invite to send the INVITE
2419 notify between routers.
2421 * Implemented the INVITE command correctly to the server.
2423 * Implemented the INVITE notify type handling in the server.
2425 * Implemented the INVITE command to the client library and on the
2428 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Added function silc_server_get_client_resolve to find the
2431 client entry by ID from all ID lists and then resolve it
2432 (using WHOIS) if it cannot be found. Affected file is
2435 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Implemented the BAN command to the client library.
2439 * The JOIN command in the server now checks the invite list
2442 * Changed the silc_command_reply_payload_encode_va and the
2443 silc_command_payload_encode_va to support that if argument is
2444 NULL it ignores and checks the next argument. Affected file
2445 lib/silccore/silccommand.c.
2447 * Added silc_server_send_notify_ban to send the BAN notify
2448 type between routers.
2450 * Chaned the silc_notify_payload_encode to support that if
2451 argument is NULL it ignores and checks the next argument.
2452 Affected file lib/silccore/silcnotify.c.
2454 * Tested ban lists in router environment successfully.
2456 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2458 * Implemented BAN command to the server, in silcd/command.[ch].
2460 * Removed the BAN and INVITE_LIST modes from the CMODE command
2463 * Added function silc_string_match to regex match two strings.
2464 Affected files lib/silcutil/silcutil.[ch].
2466 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Redefined parts of the SilcChannelEntry in the server to support
2469 the new ban and invite lists.
2471 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Redefined the INVITE command. The same command can be used to
2474 invite individuals to the channel but also to manage the invite
2475 list of the channel (to add to and remove from the invite list).
2476 Updated the protocol specs.
2478 * Added new command SILC_COMMAND_BAN that can be used to manage
2479 the ban list of the channel. Updated the protocol specs.
2481 * Removed the channel modes: the SILC_CMODE_BAN and the
2482 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2483 in the CMODE command. The equivalent features are now available
2484 using INVITE and BAN commands. Updated the protocol specs.
2486 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2487 in the network about change in the current ban list. The notify
2488 type is not used by the client.
2490 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2491 support the invite lists.
2493 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * Added new function silc_string_regexify that converts string
2496 including wildcard characters into regex string that can
2497 be used by the GNU regex library. Added into the file
2498 lib/silcutil/silcutil.[ch].
2500 Added silc_string_regex_combine to combine to regex strings
2501 into one so that they can be used as one regex string by
2502 the GNU regex library. Added into the file
2503 lib/silcutil/silcutil.[ch].
2505 Added silc_string_regex_match to match two strings. It returns
2506 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2508 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Imported GNU regex to the soruce tree into lib/contrib.
2511 Fixed some compiler warning from the regex.c.
2513 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Fixed MOTD command in the server to work in router environment.
2517 * Fixed the MOTD command in the client library to support
2518 the server argument in the command.
2520 * Added `nickname_len' argument to the silc_idlist_add_client
2521 in the server, as the `nickname' argument may be binary data
2524 * Added silc_idlist_get_channels to return all channels from
2527 * Implemented LIST command to the server. Affected file is
2530 * Implemented the LIST command to the client library and on the
2533 * Added [<user count>] argument to the LIST command reply.
2534 With private channels the user count is not shown.
2536 * Updated TODO and README.
2538 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * The client entry's data.registered must be TRUE even with
2541 global client entry on global client list. The data.registered
2542 is used to check whether the client is anymore in the network,
2543 for example with WHOWAS command so it must be valid.
2545 * Fixed the WHOWAS command in the server. It now actually works
2546 in router environment. Added function into silcd/command_reply.c
2547 silc_server_command_reply_whowas_save.
2549 * Added silc_idlist_purge function to the silcd/idlist.c
2550 to periodically purge the ID Cache.
2552 * Fixed INFO command in the server. It works now in router
2553 environment. Added <server name> argument to the INFO command
2554 reply. Updated the protocol specs.
2556 * Fixed minor bug in silc_idcache_purge to not purge if the
2557 expire value is zero.
2559 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2560 they were buggy because of the WHOWAS information.
2562 * Fixed local command MSG to handle the async resolving of
2563 the remote client properly. It used to fail the first MSG.
2564 Affected file silc/local_command.c.
2566 * Added `data_len' field to SilcIDCache context.
2568 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Update TODO. Todo in commands in the server.
2572 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2575 used by routers as broadcast packet to inform other routers
2576 about the changed user mode.
2578 Implemented the notify handling in the server. Affected file is
2579 silcd/packet_receive.c. Added the function
2580 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2582 * Added new generic Channel Payload and deprecated the New Channel
2583 Payload. The New Channel Payload is now the generic Channel
2586 * Added new argument `mode' to the silc_server_send_new_channel
2587 as it is required in the Channel Payload now.
2589 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2590 and created a new and real SilChannelPayload to represent the
2591 new generic Channel Payload. Implemented the encode/decode
2592 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2594 * Added silc_server_get_client_channel_list to return the list
2595 of channels the client has joined for WHOIS command reply.
2596 Affected file silcd/server.[ch].
2598 * Implemented the channel list sending in the WHOIS command reply
2599 in server and in the client.
2601 Implemented the channel list displaying on the user interface
2602 as well. Affected file silc/client_ops.c.
2604 * Added silc_channel_payload_parse_list to parse list of Channel
2605 Payloads. It returns SilcDList list of SilcChannelPayloads.
2606 Client for example can use this function to parse the list of
2607 channels it receives in the WHOIS command reply. The caller
2608 must free the list by calling silc_channel_payload_list_free.
2609 Affected files lib/silccore/silcchannel.[ch].
2611 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Added one new argument <user mode> to the WHOIS command reply
2614 to return the mode of the user in SILC. Updated the protocol
2617 Implemented it to the server and client.
2619 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Fixed the mode printing on the user interface on joining.
2622 Affected file silc/client_ops.c.
2624 * Implemented the UMODE command and user modes in general to the
2625 client library and to the user interface.
2627 * Implemented the UMODE command to the server.
2629 * The server now sends UNKNOWN_COMMAND error status if client sends
2630 unknown command. Affected file silcd/command.c.
2632 * All server commands now handle the command identifier the right
2633 way when sending the command reply to the client. The client can
2634 use to identify the command replies with the identifier.
2636 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Added silc_server_get_client_route to resolve the route to
2639 the client indicated by the client ID. Affected file is
2642 * Added silc_server_relay_packet as general function to relay
2643 packet to arbitrary destination. This deprecates functions
2644 like _send_private_message_key, _relay_notify etc. Affected
2645 file is silcd/packet_send.[ch].
2647 Removed silc_server_send_key_agreement,
2648 silc_server_send_private_message_key and
2649 silc_server_packet_relay_notify functions from the file
2650 silcd/packet_send.[ch].
2654 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2655 server. Affected file silcd/packet_receive.[ch].
2657 * Implemented the KILL command to the client. Implemented the
2658 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2659 Affected files lib/silcclient/command[_reply].c and
2660 lib/silcclient/client_notify.c. Implemented the KILL notify
2661 printing in the user inteface.
2663 * Fixed a lot silc_parse_nick memory leaks from the client
2664 library in the file lib/silcclient/command.c.
2666 * Changed the silc_server_send_notify_on_channels's `sender'
2667 argument from SilcSocketConnection to SilcClientEntry to
2668 check the sender as entry and not as connection object and not
2669 to send to the client provided as argument. The affected file
2670 is silcd/packet_send.[ch].
2672 * The notify packets that are destined directly to the client used
2673 to not to be processed by the server. Now changed that and the
2674 server processes all notify packets. After relaying the packet
2675 to the client the notify packet is processed in the server.
2677 * The silc_server_free_client_data now checks whether there is
2678 pending outgoing traffic for the client and purges the data to
2679 the network before removing the client entry.
2681 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2684 an client is killed from the SILC Network. Updated the protocol
2687 Added new function silc_server_send_notify_killed to the
2688 silcd/packet_send.[ch].
2690 * Added function silc_server_packet_relay_notify to relay notify
2691 packets that are destined directly to a client. In this case
2692 the server does not process the notify packets but merely relays
2693 it to the client. Affected file silcd/packet_send.[ch].
2695 Added also silc_server_packet_process_relay_notify to check
2696 whereto relay the notify. Affected file is
2697 silcd/packet_receive.[ch].
2699 * Implemented the KILL command to the server.
2703 * Added the backup schema desgined last fall to the protocol
2704 specs for everyone to see. The specification is in the
2705 *-spec-xx.txt draft and the packet type definitions for the
2706 backup routers is in *-pp-xx.txt draft. Thusly, added also
2707 new packet type SILC_PACKET_CELL_ROUTERS.
2709 * A big security problem in the implementation discovered. The
2710 signoff of an client did not cause new channel key generation
2711 which it of course should've done. The channel keys must be
2712 always re-generated when client leaves (or signoffs) the channel.
2713 The silc_server_remove_from_channels funtion now handles
2714 the channel key re-generation.
2716 * Added `sender' argument to the silc_server_send_notify_on_channels
2717 to not to send the client provided as argument. Affected file
2718 silcd/packet_send.[ch].
2720 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Implemented OPER and SILCOPER commands into the server and
2725 * Added silc_auth_verify and silc_auth_verify_data to verify
2726 the authentication directly from the authentication payload.
2727 It supports verifying both passphrase and public key based
2728 authentication. Affected file lib/silccore/silcauth.[ch].
2730 * Added `hash' field to the SilcIDListData structure. It is the
2731 hash negotiated in the SKE protocol. Affected file is
2734 * Slight redesigning of the SilcAuthPayload handling routines.
2735 Do not send SilcPKCS but SilcPublicKey as argument.
2737 * Implemented the public key authentication support to the
2738 serverconfig. The public key is loaded from the provided path
2739 and saved as authentication data to void * pointer. Thus,
2740 changed the unsigned char *auth_data to void *auth_data;
2742 * Fixed SHUTDOWN command to send the reply before the server
2743 is shutdown. :) Affected file silcd/command.c.
2745 * Fixed fatal bug in CONNECT command. The hostname was invalid
2746 memory and server crashed. Affected file silcd/command.c.
2748 * Fixed fatal bug in CLOSE command. The server_entry became
2749 invalid but was referenced later in the command. Affected file
2752 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Fixed fatal bug in failure packet handling. Server ignored
2755 the failure and thus crashed when it came.
2759 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2762 that the command may be executed only once in (about) 2 seconds.
2763 The old SILC_CF_LAG flag is same but allows command bursts up
2764 to five before limiting.
2766 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2767 server code. Various commands now includes the CF_LAG_STRICT
2768 flag to disallow any kind of miss-use of the command.
2770 * Fixed the silc_buffer_unformat to not to allocate any data
2771 if the length of the data is zero. It used to allocate the
2772 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2774 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2776 * Changed the format of AdminConnection configuration section
2777 in the server. Added username of the admin to the format.
2778 Affected files silcd/serverconfig.[ch].
2780 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2781 to return admin configuration data by host, username and/or
2784 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Implemented WHOWAS command to the server. Added the functions:
2788 silc_server_command_whowas_parse,
2789 silc_server_command_whowas_send_reply,
2790 silc_server_command_whowas_from_client and
2791 silc_server_command_whowas_from_server
2793 * Added <Client ID> argument to the WHOWAS command reply. Updated
2794 the protocol specs accordingly.
2796 * Implemented WHOWAS command and command_reply to the client
2799 Implemented the WHOWAS printing on the user interface.
2801 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Added new argument to the WHOWAS command reply, the real name.
2804 It is an optional argument. Updated the protocol specs.
2806 * Added SilcIDCacheDestructor callback that is registered when
2807 the SilcIDCache is allocated. The callback is called when
2808 an cache entry in the ID Cache expires, or is purged from the
2809 cache. Added into lib/silccore/idcache.[ch].
2811 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2812 to destruct the client entries when the cache entry expires.
2813 Other ID Cache's in server and in the client library ignores
2816 * If the ID Cache entry's `expire' field is zero then the entry
2817 never expires. Added boolean `expire' argument to the
2818 silc_idcache_add function in the lib/silccore/idcache.[ch].
2819 If it is TRUE the default expiry value is used.
2821 * Added silc_server_free_client_data_timeout that is registered
2822 when client disconnects. By default for 5 minutes we preserve
2823 the client entry for history - for WHOWAS command.
2825 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Added support to the server to enforce that commands are not
2828 executed more than once in 2 seconds. If server receives
2829 commands from client more frequently, timeout is registered
2830 to process the commands. Affected file silcd/command.c.
2831 Added new function silc_server_command_process_timeout.
2833 * Changed NICK_NOTIFY handling in client library to check that
2834 if the client's nickname was changed, so there is no need to
2835 resolve anything from the server.
2837 * Removed error printing from the WHOIS and IDENTIFY commands.
2838 If error occurs then it is ignored silently in the client library.
2839 The application, however, may map the received error to
2840 human readable error string. The application currently maps
2841 the NO_SUCH_NICKNAME error to string.
2843 * Made the command status message public to the application. Moved
2844 them from lib/silcclient/command_reply.c to
2845 lib/silcclient/command_reply.h. The application can map the
2846 received command status to the string with the
2847 silc_client_command_status_message function.
2849 * Added check to the server to check that client's ID is same
2850 as the Source ID in the packet the client sent. They must
2853 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Added dist-bzip hook to the Makefile.am to make bzip2
2856 compressed distributions.
2858 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Server now enforces the maximum length for the nickname and
2861 the channel as protocol specification dictates. 128 bytes for
2862 nickname and 256 bytes for channel name.
2864 * Moved the WHOIS printing to the application. The client libary
2865 does not print out the WHOIS information anymore, the application
2866 must do it. Renamed silc_client_command_reply_whois_print to
2867 the silc_client_command_reply_whois_save.
2869 The client's idle time is also sent to the application now, and
2870 the idle is shown on screen.
2872 * Added silc_client_command_reply_identify_save to save the
2873 received IDENTIFY entries.
2875 * Do not check for channel private keys in message sending and
2876 reception if the channel does not have the PRIVKEY mode set.
2877 Affected file lib/silclient/client_channel.c.
2879 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2882 just surfaced after chaning the JOIN procedure.
2884 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Added silc_client_get_clients_by_list to get client entries
2887 from Client ID list, that is returned for example by JOIN
2888 and USERS command replies. The application should use this
2889 function for example when JOIN command reply is received to
2890 resolve the clients already on the channel (library does not
2891 do that anymore as USERS command reply is not used in the JOIN
2892 procedure anymore). Affected files lib/silcclient/silcapi.h and
2893 lib/silcclient/idlist.c.
2895 * JOIN command reply and USERS command reply returns now SilcBuffer
2896 pointers instead of unsigned char pointers when returning
2897 the client list and mode list.
2899 * Added <Client ID> argument to the JOIN command reply, mainly
2900 for the server to identify for which client the command was
2901 originally sent. Updated protocol specs accordingly.
2903 * Added SilcDlist private_key pointer to the SilcChannelEntry
2904 in the client to support the channel private keys. Affected
2905 file is lib/silcclient/idlist.h.
2907 * Added SilcChannelPrivateKey argument to the function
2908 silc_client_send_channel_message so that application can choose
2909 to use specific private ke if it wants to. If it is not provided,
2910 the normal channel key is used, unless private keys are set.
2911 In this case the first (key that was added first) is used
2912 as the encryption key.
2914 * Implemented the support for channel private key handling.
2915 Implemented the following functions:
2917 silc_client_add_channel_private_key,
2918 silc_client_del_channel_private_keys,
2919 silc_client_del_channel_private_key,
2920 silc_client_list_channel_private_keys and
2921 silc_client_free_channel_private_keys
2923 Affected file lib/silcclient/client_channel.c.
2925 * Added the support for the private keys in the channel message
2926 sending and encryption and in the message reception and
2927 decryption. Affected funtions are
2928 silc_client_send_channel_message and silc_client_channel_message.
2930 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Added SKE's key verify callback to the client library's
2933 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2935 * Removed the statement that server (or router) must send USERS
2936 command reply when joining to the channel so that the client
2937 knows who are on the channel. Instead, the client list and
2938 client's mode list is now sent in the JOIN command reply to the
2939 client who joined channel. This is better solution.
2941 * Added function silc_server_get_users_on_channel and function
2942 silc_server_save_users_on_channel to the silcd/server.[ch].
2944 * Removed function silc_server_command_send_users from the
2947 * Do not show topic on the client library anymore. The topic is
2948 sent in the command reply notify to the application and the
2949 application must show the topic now.
2951 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Added client searching by nickname hash into the IDENTIFY and
2954 WHOIS commands in the server as they were clearly missing from
2955 them. Affected file is silcd/command.c.
2957 * Fixed a bug in private message receiving in the client library.
2958 The remote ID was freed and it wasn't supposed, now it is
2961 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Minor fix to the channel payload; allocate the data area, as it
2964 needs to be of specific length.
2966 * If the key agreement port is zero then the operating
2967 system will define the bound port. Affected files are
2968 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2970 * Added new function silc_channel_payload_decrypt into the file
2971 lib/silccore/silcchannel.[ch].
2973 * Moved the channel message etc, check from silc_packet_decrypt
2974 to applications. The library calls now a generic
2975 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2976 when the packet is either normal or special. This was done to
2977 allow more wide range of checking that was not allowed when
2978 the code was in library. Now applications can do virtually any
2979 checks to the packet and return to the library the decision how
2980 the packet should be processed. Affected files are
2981 lib/silccore/silcpacket.[ch].
2983 Added silc_server_packet_decrypt_check to the server and
2984 silc_client_packet_decrypt_check to the client library.
2986 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2987 to send with specified source and destination information.
2989 * Channel message delivery between routers was broken after the
2990 channel key distribution was fixed earlier. The channel key
2991 was used be to distributed to other routers as well which is not
2992 allowed by the protocol. Now this is fixed and channel keys
2993 really are cell specific and the channel message delivery between
2994 routers comply with the protocol specification.
2996 * Fixed various commands in server to check also the global list
2997 for the channel entry and not just the local list. The affected
2998 file silcd/command.c.
3000 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Added assert()s to buffer formatting and unformatting routines
3003 to assert (if --enable-debug) when error occurs. Affected
3004 file: lib/silcutil/silcbuffmt.c.
3006 * Changed to auto-reconnect to check whether the remote host is
3007 router and register the re-connect timeout if it is. It used
3008 to check that whether we are normal server, but router must do
3009 auto-reconnect with another router as well. Affected file
3012 * Removed the [<key len>] option from CMODE command as the cipher
3013 name decides the key length, nowadays. See the defined ciphers
3014 from the protocol specification.
3016 * Added [<hmac>] option to the CMODE command to define the HMAC
3017 for the channel. Added SILC_CMODE_HMAC channel mode.
3019 * Added [<hmac>] option for the JOIN command so that user can
3020 select which HMAC is used to compute the MACs of the channel
3023 * Added Hmac field to the Channel Message Payload. The integrity
3024 of plaintext channel messages are now protected by computing
3025 MAC of the message and attaching the MAC to the payload. The
3026 MAC is encrypted. Now, it is clear that this causes some
3027 overhead to the size of the packet but rationale for this is that
3028 now the receiver can verify whether the channel message decrypted
3029 correctly and also when private keys are set for the channel the
3030 receiver can decrypt the packet with several keys and check from
3031 the MAC which key decrypted the message correctly.
3033 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3034 lib/silccrypt/silccipher.[ch].
3036 * Added silc_hash_len to return the digest length into the
3037 lib/silcrypt/silchash.[ch].
3039 * Rewrote parts of Silc Channel Payload interface in the
3040 lib/silccore/silcchannel.[ch]. The encode function now also
3041 encrypts the packet and parse function decrypts it.
3043 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Fixed a minor formatting bug in the SKE's key material processing.
3046 It actually might have processed the keys wrong way resulting
3049 * Redefined the mandatory HMAC algorithms and added new algorithms.
3050 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3051 and hmac-md5 truncated to 96 bits. The mandatory is now
3052 hmac-sha1-96. Rest are optional (including the one that used
3053 to be mandatory). Rationale for this is that the truncated HMAC
3054 length is sufficient from security point of view and can actually
3055 make the attack against the HMAC harder. Also, the truncated
3056 HMAC causes less overhead to the packets. See the RFC2104 for
3059 * Added new [hmac] configuration section. The SKE used to use
3060 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3061 is of course wrong. The official names that must be proposed in
3062 the SKE are the ones defined in the protocol specification
3063 (hmac-sha1-96 for example). The user can configure any hmac
3064 using any hash function configured in the [hash] section. At
3065 least, the mandatory must be configured.
3067 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3069 * Added HMAC list to the SKE proposal list. It has now both
3070 hash algorithm list and HMAC list. This makes the protocol
3071 incompatible with previous versions. The SKE now seems to work
3072 the way it is supposed to work, for the first time actually.
3074 * Defined plain Hash algorithms to the protocol specification.
3077 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Implemented support for key agreement packets into the server.
3080 Added functions silc_server_key_agreement and
3081 silc_server_send_key_agreement. Other than these functions,
3082 server has nothing to do with this packet.
3084 * Added support for private message key packets into the server.
3085 Added functions silc_server_private_message_key and
3086 silc_server_send_private_message_key.
3090 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3091 called in the protocol's final callback instead in the END
3092 protocol state. This makes a little more sense and in the same
3093 time in client we can use the same protocol routines for normal
3094 key exchange and to key agreement packet handling as well.
3096 * Added to both client's and server's KE protocol context the
3097 SilcSKEKeyMaterial pointer to save the key material. We will
3098 bring the key material to the protocol's final callback by doing
3099 this. The final callback must free the key material.
3101 * Added SKE's packet_send callback into client's KE protocol
3102 context so that the caller can choose what packet sending function
3103 is used. This way we can use different packet sending when
3104 doing normal SKE when doing key agreement packet handling (in
3105 the key agreement packet handling we do not want to encrypt
3108 * Implemented the responder side of the key agreement routines
3109 in the client. The client can now bind to specified port and
3110 accept incoming key negotiation. The key material is passed
3111 to the application after the protocol is over.
3113 * Implemented the processing of incoming Key Agreement packet
3114 in the client. Added function silc_client_key_agreement to
3117 * Implemented the intiator side of the key agreement routines
3118 in the client. The client can now initiate key agreement with
3119 another remote client. The key material is passed to the
3120 application after the protocol is over.
3122 * Created client_keyagr.c to include all the key agreement
3125 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3126 SILC_TASK_CALLBACK except that it is not static.
3128 * Created client_notify.c and moved the Notify packet handling
3129 from the client.[ch] into that file.
3131 * Created client_prvmsg.c and moved all private message and
3132 private message key routines from the client.[ch] into that file.
3134 * Create client_channel.c and moved all channel message and
3135 channel private key routines from the client.[ch] into that file.
3137 * Changed silc_client_get_client_by_id_resolve to resolve with
3138 WHOIS command instead of IDENTIFY command, in the file
3139 lib/silclient/idlist.c.
3141 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Implemented the SKE's responder side to the Client library.
3145 * When FAILURE is received to the protocol do not trust it
3146 blindly. Register a timeout to wait whether the remote closes
3147 the connection as it should do it, only after that process the
3148 actual failure. This was changed to both client and server.
3150 * Added client_internal.h to include some of the structures
3151 there instead of client.h in lib/silcclient/.
3153 * Added function silc_task_unregister_by_callback to unregister
3154 timeouts by the callback function.
3156 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Some "Incomplete WHOIS info" errors has been appearing on the
3159 log files. Took away the entry->userinfo check from WHOIS
3160 reply sending. The entry->userinfo is now " " if client did not
3161 provide one. I thought this was fixed earlier but something
3162 is wrong still. Let's see if the error still appears.
3164 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Fixed a minor bug in the login when the channel key is
3167 re-generated in the server. It used to generate the key in
3168 wrong order and thus caused problems in the channel traffic.
3170 * Fixed a minor bug in channel key distsribution after
3171 KICK command. The key was not sent to the router even though
3174 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Added silc_ske_process_key_material_data as generic routine
3177 to process any key material as the SILC protocol dictates. The
3178 function is used by the actual SKE library but can be used by
3179 applications as well. This relates to the private message keys
3180 and the channel private keys since they must be processed the
3181 same way the normal SILC session keys. The protocol dictates
3182 this. Affected files: lib/silcske/silcske.[ch].
3184 Added also silc_ske_free_key_material to free the
3185 SilcSKEKeyMaterial structure.
3187 * Defined silc_cipher_set_key function to set the key for
3188 cipher without using the object's method function. The affected
3189 files: lib/silccrypt/silccipher.[ch].
3191 * Implemented silc silc_client_add_private_message_key,
3192 silc_client_add_private_message_key_ske,
3193 silc_client_del_private_message_key,
3194 silc_client_list_private_message_keys and
3195 silc_client_free_private_message_keys functions in the
3198 Added functions silc_client_send_private_message_key to send
3199 the Private Message Key payload and silc_client_private_message_key
3200 to handle incoming Private Message Key payload.
3202 * Added Cipher field to the Private Message Key payload to set
3203 the cipher to be used. If ignored, the default cipher defined
3204 in the SILC protocol (aes-256-cbc) is used.
3206 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Removed lib/silcclient/ops.h file.
3210 Redefined parts of the SILC Client Library API. Created new
3211 file silcapi.h that deprecates the ops.h file and defines the
3212 published Client Library API. Defined also private message key
3213 API and channel private key API into the file.
3215 This is the file that the application must include from the
3216 SILC Client Library. Other files need not be included by
3217 the application anymore.
3219 * Added new key_agreement client operation callback and also
3220 defined the Key Agreement library API for the application.
3222 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3225 is used by clients to request key negotiation between another
3226 client in the SILC network. If the negotiation is started it
3227 is performed using the SKE protocol. The result of the
3228 negotiation, the secret key material, can be used for example
3229 as private message key.
3231 Implemented the Key Agreement payload into the files
3232 lib/silccore/silauth.[ch].
3234 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Redefined ciphers for the SILC protocol. Added some new ciphers
3237 and defined the key lengths for the algorithms. Changed the
3238 code accordingly. The default key length is now 256 bits.
3240 * Fixed SKE key distribution function silc_ske_process_key_material
3241 when the key length is more than 128 bits. The default key
3242 length in SILC is now 256 bits.
3244 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3245 to indicate unsupported algorithm.
3247 * Renamed rijndael.c to aes.c and all functions as well.
3249 * Fixed a long standing channel key setting bug in client library.
3250 Weird that it has never surfaced before.
3252 * Fixed bug in channel deletion. If the entire channel is removed
3253 then it must also delete the references of the channel entry
3254 from the client's channel list as the client's channel entry and
3255 the channel's client entry share same memory.
3257 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Implemented CONNECT and SHUTDOWN commands in the client.
3261 * Implemented CLOSE command to the client.
3263 * Added the function silc_idlist_find_server_by_name into the
3264 files silcd/idlist.[ch].
3266 Added the function silc_idlist_find_server_by_conn into the
3267 files silcd/idlist.[ch].
3269 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * DIE command was renamed to SHUTDOWN. Updated the both code
3274 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3275 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3277 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3280 * Added function silc_server_create_connection function to create
3281 connection to remote router. My server implementation actually
3282 does not allow router to connect to normal server (it expects
3283 that normal server always initiates the connection to the router)
3284 so the CONNECT command is only good for connecting to another
3287 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3290 or some other client was kicked from the channel.
3292 Implemented the handling of the notify type to both client
3295 Implemented silc_server_send_notify_kicked to send the KICKED
3296 notify. It is used to send it to the server's primary router.
3298 * Implemented the KICK command into server and client.
3300 * Added `query' argument to the silc_idlist_get_client function
3301 to indicate whether to query the client from server or not if
3304 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3305 to indicate that the client is not channel founder.
3309 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Removed the rng context from SilcPacketContext structure and
3312 changed that the packet routine uses the Global RNG API.
3314 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3316 * Added support for quit message that client can "leave" on the
3317 channel when it quits the SILC. It is ditributed inside the
3318 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3320 Added silc_server_free_client_data that will take the
3321 signoff message as argument.
3323 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3325 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Updated parts of the protocol specification to keep it up
3330 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3333 payloads in one packet.
3335 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3336 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3337 use now the new List flag.
3339 * Also deprecated the following packet types: REPLACE_ID,
3340 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3342 * Added list support for Notify packet in server.
3344 * Added silc_server_send_notify_channel_change to send the
3345 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3346 the silc_server_send_replace_id.
3348 * Added silc_server_send_notify_nick_change to send the
3349 NICK_CHANGE notify type. Deprecates the function
3350 silc_server_send_replace_id.
3352 * Added silc_server_send_notify_join to send the JOIN notify type.
3353 Deprecates the function silc_server_send_new_channel_user.
3355 * Added silc_server_send_notify_leave to send LEAVE notify type.
3356 Deprecates the function silc_server_send_remove_channel_user.
3358 * Added silc_server_send_notify_cmode and
3359 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3360 types. Deprecates the silc_server_send_set_mode function.
3362 * Added SERVER_SIGNOFF notify type to indicate that server has
3363 quit. This means that all clients on the channel from that
3364 server will drop. This can be also used when netsplit happens.
3366 Deprecated REMOVE_ID packet type since it is not needed anymore
3369 Added silc_server_send_notify_server_signoff to send the
3370 SERVER_SIGNOFF notify type. Deprecates the function
3371 silc_server_send_remove_id.
3373 Added also silc_server_send_notify_signoff to send the
3374 SIGNOFF notify type.
3376 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3377 SILC protocol from this day on. Changed the protocol
3378 specification as well.
3380 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3381 notify type. It is used between routers to notify about
3382 topic changes on a channel.
3384 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3387 * Partly updated the protocol specification to comply with the
3388 changes now made. It is still though a bit outdated.
3390 * The JOIN notify type now takes one extra argument <Channel ID>.
3391 The packet used to be destined to the channel but now the
3392 JOIN type may be sent as list thus it is impossible to
3393 destine it to any specific channel. By adding this argument
3394 it is again possible.
3396 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Added CREDITS file. The CHANGES and CREDITS file will appear
3399 in the distribution as well.
3401 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3404 types in the server's silcd/packet_receive.c.
3406 * Implemented CMODE and CUMODE to work in router environment.
3408 * Fixed minor encoding and decoding buglet from the
3409 lib/silccore/silcmode.c.
3411 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3414 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3416 * Changed all SilcConfigServer* and silc_config_server* to
3417 SilcServerConfig* and silc_server_config*, respectively.
3420 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Associated the ID (client or server ID) to the Authentication
3423 Payload to avoid any possibility of forging. Updated the
3424 protocol specification and the code accordingly.
3426 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * The RSA key length is now save to the RsaKey context in the
3429 key generation process in lib/silccrypt/rsa.c. The key length
3430 is now used to figure out the maximum size of the block allowed
3431 to be encrypted/signed.
3433 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3434 is equivalent to the silc_mp_mp2bin but does not allocate any
3437 * Changed silc_mp_mp2bin API to take length argument. If it is
3438 non-zero then the buffer is allocated that large. If zero, then
3439 the size is approximated using silc_mp_sizeinbase, which however
3442 * Created Global RNG API which is global RNG that application can
3443 initialize. After initializing, any routine anywhere in the
3444 code (including library) can use RNG without allocating a new
3445 RNG object. This was done to allow this sort of use of the
3446 RNG in code that has no chance to allocate RNG object. All
3447 applications currently allocate this and many routines in the
3448 library use this. Affected file lib/silccrypt/silcrng.[ch].
3450 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3451 it to use the Global RNG API.
3453 * Defined Authentication Payload into protocol specification that
3454 is used during SILC session to authenticate entities. It is
3455 used for example by client to authenticate itself to the server
3456 to obtain server operator privileges.
3458 Implemented this payload into the lib/silccore/silcauth.[ch].
3459 Implemented also routines for public key based authentication
3460 as the new protocol specification dictates.
3462 Moved definitions of different authentication methods from
3463 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3465 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3466 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3467 silc_pkcs_verify_with_hash functions into the file
3468 lib/silccrypt/silcpkcs.[ch].
3470 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * The client entry's userinfo pointer must be always valid.
3473 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3474 will fail since it requires the userinfo. Now, the userinfo
3475 is allocated as "" if actual userinfo does not exist. Actually,
3476 it must exist and it is totally Ok to drop client connections
3477 that does not announce the userinfo. However, we will make
3478 this workaround for now.
3480 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3481 to return the remote port by socket.
3483 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3486 SILC_SERVER_PENDING_EXEC and added an new macro
3487 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3488 data or when error occurs while processing the pending command.
3490 Added new argument `destructor' into silc_server_command_pending
3491 and to the SilcServerCommandPending object. This destructor is
3492 now called after calling the pending callback or if error occurs
3493 immediately. If error occurs the actual pending callback won't
3494 be called at all - only the destructor. The destructor may be
3495 NULL if destructor is not needed.
3497 All this applies for client library code as well. Similar
3498 changes were made there as well for the pending commands.
3500 In the client, the application must now allocate the
3501 SilcClientCommandContext with the silc_client_command_alloc
3504 * Added reference counter to the SilcServerCommandContext. Added
3505 function silc_server_command_alloc and silc_server_command_dup
3508 Same type of functions added to the client library for the same
3511 * Removed the cmd_ident from IDListData away since it is now
3512 global for all connections. It is the command identifier used
3513 in command sending and with pending commands. The affected file
3516 * Added reference counter to the SilcSocketConnection objecet to
3517 indicate the usage count of the object. The object won't be
3518 freed untill the reference counter hits zero. Currently only
3519 server uses this, and client ignores it. The client must be
3520 set to use this too later. The affected files are
3521 lib/silccore/silcsockconn.[ch]. Added also the function
3522 silc_socket_dup to increase the reference counter.
3524 This was mainly added because it is possible that the socket
3525 is removed underneath of pending command or other async
3526 operation. Now it won't be free'd and proper DISCONNECTING
3527 flags, etc. can be set to avoid sending data to connection that
3528 is not valid anymore.
3530 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3531 the connection. After that it sets SILC_SET_DISCONNECTED.
3532 It is, however, possible that the socket data is not still freed.
3533 The silc_server_packet_process now checks that data is not
3534 read or written to connection that is DISCONNECTED. The socket
3535 get's freed when the reference counter hits zero.
3537 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Changed the client operation API: channel_message operation's
3540 `sender' is now the client entry of the sender, not the nickname
3541 and the `channel' is the channel entry, not the channel name.
3543 In the private_message operation the `sender' is now also the
3544 client entry of the sender not the nickname.
3546 Affected file is lib/silcclient/ops.h and all applications
3547 using the client operations.
3549 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Moved the calling of ops->connect() from connect_to_server_final
3552 into receive_new_id functin since that is the point when the
3553 client is actually allowed to send traffic to network. The
3554 affected file is lib/silcclient/client.c.
3556 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3559 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3560 (if needs broadcasting) instead of broadcasting the packets one
3561 by one which would make a burst in the network traffic.
3563 * Added `broadcast' argument to the functions in silcd/server.[ch]
3564 silc_server_create_new_channel[_with_id] to indicate whether
3565 to send New Channel packet to primary router.
3567 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Added new function into the silcd/server.[ch] files:
3570 silc_server_create_new_channel_with_id to create new channel with
3571 already existing Channel ID.
3573 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3574 lib/silccore/silcpacket.h. This packet is used t send list of
3575 Set Mode payloads inside one packet. Server uses this to set
3576 the modes for the channels and clients on those channels, that it
3577 announced to the router when it connected to it. The protocol
3578 specification has been updated accordingly.
3580 * The silc_server_new_channel did not handle the packet coming
3581 from normal server as it normally does not send that. However,
3582 when it announces its channels it does send it. Implemented
3583 the support for that.
3585 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3586 into the file lib/silccore/id.h.
3588 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Fixed memory leaks in the functions silc_idlist_del_client,
3591 silc_idlist_del_channel and silc_idlist_del_server in the file
3592 silcd/idlist.c. All of those leaked like a sieve.
3594 * Fixed some small memory leaks in the client's function
3595 silc_client_notify_by_server.
3597 * Added functions into silcd/server.c: silc_server_announce_clients,
3598 silc_server_announce_channels and silc_server_announce_server.
3599 These functions are used by normal and router server to announce
3600 to its primary router about clients, channels and servers (when
3601 router) that we own. This is done after we've connected to the
3604 These functions effectively implements the following packet types:
3605 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3606 and SILC_PACKET_NEW_ID_LIST.
3608 * Added new functions into the silcd/packet_receive.[ch]:
3609 silc_server_new_id_list, silc_server_new_channel_list and
3610 silc_server_new_channel_user_list to handle the incoming
3611 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3613 * Added support of changing Channel ID in the function
3614 silc_server_replace_id. If the server that announces a channel
3615 to the router already exists in the router (with same name but
3616 with different Channel ID), router is responsible to send
3617 Replace ID packet to the server and force the server to change
3618 the Channel ID to the one router has.
3620 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3621 client that the Channel ID has been changed by the router. The
3622 normal server sends this to the client. Client must start using
3623 the new Channel ID as the channel's ID.
3625 Implemented handling of this new type into lib/silcclient/client.c
3626 into the function silc_client_notify_by_server.
3628 * Added new function silc_idlist_replace_channel_id into the files
3629 silcd/idlist.[ch] to replace the Channel ID.
3631 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Call silc_server_command_identify_check always when processing
3634 the IDENTIFY command in silcd/command.c
3636 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3639 send keepalive packets. The packet can be sent by clients,
3640 servers and routers.
3642 Added function silc_socket_set_heartbeat into the file
3643 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3644 If not set, the heartbeat is not performed. The actual
3645 heartbeat is implemented in the low level socket connection
3646 library. However, application is responsible of actually
3649 Added silc_server_send_heartbeat to send the actual heartbeat
3650 packet into silcd/packet_send.[ch]. Server now performs
3651 keepalive with all connections.
3653 * Added silc_task_get_first function into lib/silcutil/silctask.c
3654 to return the timeout task with shortest timeout. There was a bug
3655 in task unregistration that caused problems. TODO has been
3656 updated to include that task system must be rewritten.
3658 * The client library will now resolve the client information when
3659 receiving JOIN notify from server for client that we know but
3660 have incomplete information.
3662 * Rewrote parts of silc_server_remove_from_channels and
3663 silc_server_remove_from_one_channel as they did not remove the
3664 channel in some circumstances even though they should've.
3666 * Encryption problem encountered in server:
3668 The LEAVE command used to send the Channel Key packet to the
3669 router immediately after generating it. However, the code
3670 had earlier sent Remove Channel user packet but not immediately,
3671 ie. it was put to queue. The order of packets in the router
3672 was that Channel Key packet was first and Remove Channel User
3673 packet was second, even though they were encrypted in the
3674 reverse order. For this reason, MAC check failed. Now, this
3675 is fixed by not sending the Channel Key packet immediately but
3676 putting it to queue. However, this is more fundamental problem:
3677 packets that are in queue should actually not be encrypted
3678 because packets that are sent immediately gets encrypted
3679 actually with wrong IV (and thus MAC check fails). So, packets
3680 that are in queue should be encrypted when they are sent to
3681 the wire and not when they put to the queue.
3683 However, the problem is that the current system has not been
3684 designed to work that way. Instead, the packet is encrypted
3685 as soon as possible and left to the queue. The queue is then
3686 just purged into wire. There won't be any fixes for this
3687 any time soon. So, the current semantic for packet sending
3690 o If you send packet to remote host and do not force the send
3691 (the packet will be in queue) then all subsequent packets to the
3692 same remote host must also be put to the queue. Only after the
3693 queue has been purged is it safe again to force the packet
3696 o If you send all packets immediately then it safe to send
3697 any of subsequent packets through the queue, however, after
3698 the first packet is put to queue then any subsequent packets
3699 must also be put to the queue.
3701 Follow these rules and everything works fine.
3703 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Added new function silc_server_remove_clients_by_server to
3706 remove all client entries from ID list when the server connection
3707 is lost. In this case it is also important to invalidate all
3708 client entires as they hold the invalid server entry. This
3709 fixes fatal bug when server has lost connection and will reconnect
3712 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Made some sanity checks to silc_server_daemonise like to check
3715 whether the requested user and group actually exists.
3717 * Added sanity check to SKE's silc_ske_responder_finish to check
3718 that the public and private key actually is valid.
3720 * Invalidate the client's nickname when receiving Replace ID
3721 packet and the Client ID is being replaced. This means that the
3722 server will query the nickname if someone needs it (client)
3725 * Sort the ID Cache in client library when the ID Cache data
3726 has changed (needs sorting).
3728 * Do not allow for SILC client to create several connections to
3729 several servers. The client does not support windows right now
3730 and generating multiple connections causes weird behaviour.
3732 Irssi-silc client does support windows and can handle several
3733 connections without problems, see: www.irssi.org and SILC plugin.
3735 * Fixed some places where client was added to the IDList. The
3736 rule of thumb is following (in order to get everything right):
3737 If the client is directly connected local client then the
3738 `connection' argument must be set and `router' argument must be
3739 NULL to silc_idlist_add_client function. If the client is not
3740 directly connected client then the `router' argument must
3741 bet set and the `connection' argument must be NULL to the
3742 silc_idlist_add_client function.
3744 * The funtion silc_server_packet_send_local_channel actually did
3745 not check whether the client was locally connected or not. It
3746 does that now. Fixed a bug related to LEAVE command.
3748 * Fixed Remove Channel User payload parsing bug in server's
3749 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3751 * The server's silc_server_save_channel_key now checks also the
3752 global ID list for the channel as it might not be in the local
3753 list. Fixed a bug related to LEAVE command.
3755 * Is this the end of the [<unknown>] buglet that has been lurking
3756 around for a long time? A little for loop fix in server's
3757 silc_server_command_whois_parse that is used by both IDENTIFY
3758 and WHOIS command. At least, this was a clear bug and a cause
3759 of one type of [<unknown>] buglet.
3761 * WHOIS and IDENTIFY commands call the function
3762 silc_server_command_[whois/identify]_check function even if
3763 we are not router server.
3765 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Added --with-gmp configuration option. If set the GMP
3768 is always compiled in the SILC source tree. If not set then
3769 it is checked whether the system has the GMP3 installed. If
3770 it has then the GMP won't be compiled (the system's headers
3771 and library is used), if it doesn't have it then the GMP is
3772 compiled in the SILC source tree.
3774 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Changed RSA private exponent generation to what PKCS #1
3777 suggests. We try to find the smallest possible d by doing
3778 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3779 not security fix but optimization.
3781 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Added new config entry [Identity] to fork the server and run
3784 it as specific user and group. A patch from Bostik.
3786 * Imported Dotconf configuration library into lib/dotconf.
3787 This will be used to create the SILC configuration files later.
3788 It will appear in the distsribution after this commit.
3790 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * A big code auditing weekend happening. Auditing code for
3793 obvious mistakes, bugs and errors. Also, removing any code
3796 Removed files for being obsolete:
3798 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3799 inline in the file lib/silcutil/silcbuffer.h)
3801 o lib/silcutil/silcbufutil.c (the header has inline versions)
3803 Changed code to fix possible error conditions:
3805 o The buffer formatting routines now check that the destination
3806 buffer really has enough space to add the data. This applies for
3807 both buffer formatting and unformatting
3808 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3809 unformatting was changed to accomodate following rules:
3810 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3811 sent to the function while XXX_*STRING will not allocate or copy
3812 the data into the buffer. Instead it sets the pointer from the
3813 buffer into the pointer sent as argument (XXX_*STRING used to
3814 require that the pointer must be allocated already). This change
3815 makes this whole thing a bit more consistent and more optimized
3816 (note that the data returned in the unformatting with XXX_*STRING
3817 must not be freed now). The routines return now -1 on error.
3819 o Tried to find all code that use buffer_format and buffer_unformat
3820 and added return value checking to prevent formatting and
3821 especially unformatting errors and possible subsequent fatal
3824 o Changed ske->x and ske->KEY to mallocated pointers in
3825 lib/silcske/silcske.h. Fixed possible data and memory leak.
3827 o Added return value checking to all *_parse* functions. Fixed
3828 many memory leaks as well.
3830 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3831 so that buffer overflows would not happen. All code now also
3832 checks the return value as it can fail.
3834 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added reconnection support to server if the normal server looses
3837 its connection to the router (for example if router is rebooted).
3838 The server performs normal reconnection strategy implemented
3839 to the server. Affected file silcd/server.c.
3841 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added new packet type SILC_PACKET_SET_MODE that is used to
3844 distribute the information about changed modes (for clients,
3845 channels and clients channel modes) to all routers in the
3846 network. Updated the protocol specification accordingly.
3848 Added functions into silcd/packet_send.c and
3849 silcd/packet_receive.c: silc_server_send_set_mode,
3850 silc_server_set_mode.
3852 Added new files silcmode.[ch] into lib/silccore that implements
3853 the encoding and decoding of Set Mode Payload. Added new type
3854 SilcSetModePayload. Moved the definitions of different modes
3855 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3857 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Oops, a little mistake in server's connection authentication
3860 protocol. The protocol is not ended with FAILURE but with
3861 SUCCESS if the authentication is Ok. :) Affected file is
3864 * Implemented NICK_CHANGE notify handling in server in the file
3865 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3866 the local clients on the channel. After the changing nickname
3867 in router environment snhould work and the [<unknown>] nickname
3868 should appear no more.
3870 The silc_server_replace_id function that receives the Replace ID
3871 payload now sends the NICK_CHANGE notify type also in the file
3872 silcd/packet_receive.c
3874 * Changed WHOIS and IDENTIFY command to support the maximum amount
3875 of arguments defined in protocol specs (3328 arguments). This
3876 fixed a bug that caused problems when there were more than three
3879 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Added extra parameter, command identifier, to the
3882 silc_client_send_command so that explicit command identifier
3885 Changed that ID list routines uses specific command identifier
3886 when sending WHOIS/IDENTIFY requests to the server so that they
3887 can be identified when the reply comes back.
3889 Affected files lib/silcclient/command.[ch],
3890 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3892 * Added `sender' argument to silc_server_packet_send_to_channel
3893 to indicaet the sender who originally sent the packet to us
3894 that we are now re-sending. Ignored if NULL. Affected file
3895 silcd/packet_send.[ch].
3897 * Added some server statistics support in silcd/server_internal.h
3898 SilcServerStatistics structure and around the server code. Also
3899 send some nice statistics information when client is connecting
3902 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3904 * Fixed channel ID decoding in server's JOIN command reply in
3905 silcd/command_reply.c
3907 * Fixed braodcasting of replace ID payload to not to send it if
3908 we are standalone server in silcd/packet_receive.c.
3910 * Fixed all channel message sending routines to not to send
3911 packets to clients that has router set, since they are routed
3912 separately in the same function earlier. Affects file
3913 silcd/packet_send.c and all channel packet sending functions.
3915 * In USERS reply, res_argv[i] are not allocated, the table
3916 is allocated. Thus changed that free the table, not its
3919 * In server's whois_check and identify_check if the client is
3920 locally connected do not send any WHOIS commands - they are not
3923 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Fixed some minor bugs in client when sending WHOIS command. The
3926 arguments was in wrong order.
3928 * Removed statis function add_to_channel from server in
3929 silcd/command.c that was previously used with the joining but
3932 * Tested USERS command in router environment successfully with two
3933 routers, two servers and two clients.
3935 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Reorganized the USERS command and command reply in client library
3938 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3939 When the command is given by user we register a pending command
3940 callback that will reprocess the command after the reply has been
3941 received from the server. When reprocessing the packet we then
3942 display the information. Thus, the USERS information is displayed
3943 now in the command callback instead of in the command reply
3944 callback. The processing of the command is same as previously
3945 when server has sent the command reply in the JOINing process.
3947 * Added to USERS command in silcd/command_reply.c to join the client,
3948 we didn't use to know about, to the channel after we've created
3949 a client entry for it. Also, for clienet we did know already still
3950 check whether it is on the channel or not and add it if not.
3952 * Removed silc_server_command_join_notify as the function and its
3955 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Changed the client's pending command handling to the same as the
3958 server's pending command handling. It is also now possible to
3959 execute command reply functions from other command reply
3960 function as the function callbacks for commands and command
3961 replies are one and same. The pending commands are not static
3962 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3963 in client connection context. Thus, pending commands are server
3964 connection specific as it is convenient.
3966 Changed the function silc_client_command_pending and
3967 silc_client_command_pending_del and added new function
3968 silc_client_command_pending_check. Removed the
3969 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3972 * Added cmd_ident, current command identifier, to the client
3973 connection context in lib/silcclient/client.h to keep track on
3974 command identifiers used in command sending. Client's command reply
3975 function handling now supports the mandatory command identifiers.
3977 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3978 funtions in client to fully support pending command callbacks.
3980 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3981 as one of the arguments to the application in the command reply
3984 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3985 before first releasing SILC but came back. Now it is removed again
3986 and should come back nomore. The FORWARDED flag was used only
3987 by the JOINing procedure by forwarding the command packet to router.
3988 Now, the JOINing procedure has been changed to more generic (due
3989 to various router environment issues) and FORWARDED is not needed
3990 anymore for anything. The protocol specification is yet to be
3993 Now, removed silc_server_packet_forward from server and the flag
3994 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3996 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Renamed NAMES command to USERS command. The NAMES was named that
3999 due to historical reasons. Now it is renamed. Also, rewrote
4000 parts of the USERS command. The nickname list is not sent anymore
4001 by the server. Only Client ID and mode lists are sent in the USERS
4002 command. Changed this also to the protocol specification.
4004 The client now resolves the names and stuff after it receives
4005 the USERS list from the server when joining to the channel.
4007 * WHOIS and IDENTIFY commands has been changed to support multiple
4008 Client ID's per command. One can now search for multiple users
4009 in the network by sending only one WHOIS or IDENTIFY command.
4010 Changed the code and the protocol specifications.
4012 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4013 uses silc_server_command_whois_parse to parse the request. */
4015 * If normal server, do not parse the WHOIS and IDENTIFY requests
4016 before sending it to the router. Saves some time.
4018 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Fixed JOIN command on client library. Wrong number of arguments
4021 used to crash the client.
4023 * Added silc_server_channel_has_global function to check whether
4024 channel has global users or not.
4026 * Added silc_server_channel_has_local function to check whether channel
4027 has locally connected clients on the channel.
4029 * The silc_server_remove_from_one_channel now checks whether the
4030 channel has global users or not after given client was removed from
4031 the channel. It also checks whether the channel has local clients
4032 on the channel anymore. If it does not have then the channel entry
4033 is removed as it is not needed anymore.
4035 * The silc_server_notify now checks on JOIN notify whether the joining
4036 client is one of locally connected or global. If it is global then
4037 the channel has now global users on the channel and that is marked
4038 to the channel entry. Also, it now saves the global client to
4039 global list who is joining and JOINs it to the channel. This is
4040 for normal server, that is.
4042 Changed silc_server_send_notify_on_channel,
4043 silc_server_packet_relay_to_channel and
4044 silc_server_packet_send_to_channel check if we are normal server
4045 and client has router set (ie. global client) do not send the
4046 message to that client, as it is already routed to our router.
4048 * Implemented LEAVE notify type handling in silc_server_notify
4051 * Tested LEAVE command in router environment successfully. Tested
4052 with two routers, two servers and two clients.
4056 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4058 * Implemented SIGNOFF notify type handling in silc_server_notify
4061 * silc_server_remove_id now removes the client entry from all channels
4062 it has joined and thusly sends SIGNOFF notify type.
4064 * Rewrote the NAMES list generation in server by removing two excess
4065 loops. The lists are created now inside one loop.
4067 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * silc_server_remove_channel_user checks now also global list
4070 for channel and client.
4072 * silc_server_new_channel_user checks now both local and global
4073 list for channel and client. Fixed a bug in client id decoding.
4074 Used to decode wrong buffer.
4076 * silc_server_channel_message checks now both local and global
4077 list for channel entry.
4079 * Tested channel joining (hence JOIN) in router environment
4080 successfully. Tested with two routers, two servers and two
4083 * Tested channel message sending in router environment successfully.
4085 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Added silc_server_save_channel_key into server.[ch] to save the
4088 received channel key in Channel Key payload processing. It is
4089 also used in JOIN command reply handling.
4091 Equivalent function silc_client_save_channel_key added into
4092 client.[ch] into client library.
4094 * Changed JOIN command reply to send information whether the channel
4095 was created or not (is existing already) and the channel key
4096 payload. Changed protocol specs accordingly.
4098 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4099 the request was sent by ID and not by nickname. Crashed on
4102 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4105 now correctly save the received data.
4107 * silc_server_free_sock_user_data now notifies routers in the
4108 network about entities leaving the network.
4110 At the same time implemented functions silc_server_remove_id
4111 and silc_server_send_remove_id to receive and send REMOVE_ID
4112 packets. The packet is used to notify routers in the network
4113 about leaving entities. The ID removed will become invalid in
4116 * Added function silc_idlist_del_server into server. Removes and
4117 free's server entry from ID list.
4119 * silc_server_private_message function now checks, if we are router,
4120 that the destination ID really is valid ID, naturally.
4122 * In router when NEW_ID packet is received (for new client) the
4123 hash of the Client ID is saved in the ID Cache but the
4124 client->nickname is set to NULL, instead of putting the hash
4127 IDENTIFY command now also checks that client->nickname must be
4128 valid. If it is not if will request the data from the server who
4129 owns the client. Added new function
4130 silc_server_command_identify_check.
4132 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4133 to set the command to already allocated Command Payload.
4135 * Tested private message sending in router environment with two
4136 routers, two servers and two clients. Fixed minor bugs and now
4139 * Fixed segfault from client's NAMES command. Used to crash if
4142 * Forwarded packets must not be routed even if it is not destined
4143 to the receiver. Changed server code comply with this.
4145 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Added `require_reverse_mapping' boolean value to ServerParams
4148 structure. If TRUE (not default) the server will require that
4149 the connecting host has fully qualified domain name.
4151 If the reverse mapping is not required and hostname could not be
4152 found the IP address is used as hostname.
4154 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Implemented version string checking to both client and server.
4157 The check is incomplete currently due to the abnormal version
4158 strings used in development version of SILC.
4160 * Changed all command functions in server to use the new
4163 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Changed char *data to unsigned char *data in ID Cache system to
4166 support binary data as ID Cache data. Changed code to support
4167 binary data in lib/silccore/idcache.c.
4169 * Renamed silc_server_packet_relay_command_reply to
4170 silc_server_command_reply as it is normal packet receiving
4171 function. Rewrote the function to accept command replys for
4172 servers and not only for clients.
4174 * Mark remote router always as registered server if we are connecting
4175 to it. Otherwise, commands sent by the router to us are ignored.
4177 * All ID List find routines now returns the ID Cache Entry pointer
4178 as well if requested.
4180 * WHOIS command works now in router environment, tested with two
4181 routers, two servers and two clients.
4183 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4184 in router environment (as it is almost equivalent to WHOIS) but
4185 hasn't been tested thoroughly. Added new functions:
4187 silc_server_command_identify_parse
4188 silc_server_command_identify_send_reply
4189 silc_server_command_identify_from_client
4190 silc_server_command_identify_from_server
4192 * Disabled route cache adding because adding two different ID's with
4193 same IP replaces the old cache entry thus giving wrong route.
4194 The entry->router->connection is always the fastest route anyway
4195 so route cache may not be needed. Of course, new routes maybe
4196 established after receiving the ID when the entry->router->connection
4197 might not be anymore the most optimal.
4199 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Add route cache for received ID for fast routing.
4203 * Added silc_server_packet_route to route received packet on router
4204 that is not destined to us.
4206 * Renamed silc_server_get_route to silc_server_route_get.
4208 * Added id_string and id_string_len fields into SilcServer to
4209 include encoded ServerID for fast comparing without excess
4210 encoding of the ID's.
4212 * Cleaned up WHOIS command on server side. Added following static
4215 silc_server_command_whois_parse
4216 silc_server_command_whois_check
4217 silc_server_command_whois_send_reply
4218 silc_server_command_whois_from_client
4219 silc_server_command_whois_from_server
4221 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4222 arguments in command replies. All command functions should be
4223 updated to use this macro.
4225 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Minor typo fixes on command reply handling on server.
4229 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added silc_server_command_add_to_channel internal routine to add
4232 the client to the channel after router has created the channel and
4233 sent command reply to the server.
4235 * Added generic silc_server_send_command to send any command from
4238 * Use static buffer with ID rendering instead of duplicating data.
4240 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Fixed a channel user mode bug when joining to a channel server gave
4243 everybody channel founder rights, oops.
4245 * We mark ourselves as the router of the incoming server connection
4246 if we are router ourselves. This way we can check in some packet
4247 sending functions whether it is locally connected server. For
4248 incoming router connections we put NULL.
4250 * For router sending packets locally means now always sending the
4251 packet cell wide; to local clients and local servers. For normal
4252 server sending packet locally means sending it to only local
4255 * Fixed the JOIN command to really work in router environment. If the
4256 channel is created it is always created by the router. Router is
4257 also responsible of making the initial joining to the channel,
4258 sending JOIN notify to the sending server and distributing
4259 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4260 does not exist server doesn't do anything else but forward the
4261 command to the router which performs everything.
4263 * Added silc_server_send_channel_key function to send the Channel Key
4266 * Added silc_server_create_channel_key to create new channel key. The
4267 channel key is now re-generated everytime someone joins or leaves
4268 a channel, as protocol dictates. Note: channel->key_len is the
4271 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4274 packet_receive.[ch] to separate packet sending and receiving
4275 routines. The server.[ch] now includes everything else including
4276 actual packet processing (writing and reading data) and other
4279 Renamed silc_server_private_message_send_internal to
4280 silc_server_send_private_message. The routine is still though
4281 used only to relay private messages as server does not send
4282 private messages itself.
4284 Renamed silc_server_new_channel to silc_server_create_new_channel
4285 and added new function sicl_server_new_channel that handles the
4286 incoming New Channel packet. Added also new sending function
4287 silc_server_send_new_channel to send New Channel Payload.
4289 * Added new function silc_server_notify to process incoming notify
4290 packet to the server/router. Server may then relay the notify
4291 to clients if needed.
4293 * Added new function silc_server_new_channel_user to process incoming
4294 New Channel User packet. Router will redistribute the packet and
4295 send JOIN notify to its local clients and locally connected servers
4296 if needed. Normal server will send JOIN notify to its local client
4297 on same channel when received this packet. Added also corresponding
4298 sending function silc_server_send_new_channel_user to sent the
4301 * Added boolean route argument to send_notif_to_channel and
4302 packet_send_to_channel functions to attempt to route the packet
4303 if it is TRUE and send only locally if it is FALSE.
4305 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * silc_server_replace_id now broadcasts the received replace ID
4308 packet if it is not broadcast packet already. The router must
4309 broadcast to inform other routers about changed ID.
4311 * Added backpointer to server's router into SilcServer context in
4312 silcd/server_internal.h.
4314 * Fixed silc_server_packet_broadcast to send correct broadcast
4317 * The channel key is now distributed to the local client as soon
4318 as it is received from the router (in router environment) so that
4319 no other packet may be sent for the channel until client has
4322 * silc_server_remove_channel_user now broadcasts the received
4323 Remove Channel User packet if it is not broadcast packet already.
4324 The router must broadcast to inform other routers about removed
4327 * Added users field into SilcPacketContext that is a reference count
4328 of the context. One can increase the reference count by calling
4329 silc_packet_context_dup which is now changed to just increase the
4330 reference count instead of duplicating the data. The reference
4331 count is decresed by calling silc_packet_context_free that will
4332 free the data after the reference count hits zero.
4334 For now on the packet context and everything allocated into it
4335 (including the raw packet from network) must be freed by calling
4336 the new silc_packet_context_free function. Added also new function
4337 silc_packet_context_alloc that must be used now to allocate the
4338 context. This also means that if a routine is asynchronous from
4339 silc_[client/server]_packet_parse_type the packet context must
4340 be duplicated by calling silc_packet_context_dup. Otherwise it
4341 gets free'd after silc_[client/server]_packet_parse_type returns.
4342 Also, one must remember that if packet is duplicated then its
4343 reference count must be decresed by calling the free function as
4344 many times as it was duplicated.
4346 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4347 from both client and server.
4349 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Made joining to a channel working in router environment.
4353 * Cleaned up JOIN command on server side and create function
4354 silc_server_command_join_channel internal routine to make the
4357 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Changed silc_command_pending list to SilcDList. Also, added
4360 `ident' field to SilcServerCommandPending structure to identify
4361 the reply and to call correct callback.
4363 Added silc_server_command_pending_check function to replace the
4364 corresnponding macro. The silc_command_pending list is not
4367 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4368 to set identifier to previously allocated Command Payload. It
4369 is used to set identifier for command when resending Command
4372 * Added silc_command_payload_encode_payload to encode Command
4373 Payload buffer from SilcCommandPayload structure.
4375 * Added silc_argument_payload_encode_payload to encode Argument
4376 payload buffer from SilcArgumentPayload structure.
4378 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Changed WHOIS command to support router connection on server side.
4381 The whois request is always sent to router unless the server is
4382 standalone server. After server has received the reply from the
4383 router will it send the reply to the client.
4385 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4386 broadcast received broadcast packet. The function is used only
4387 by router. The broadcast packet is always sent to the router's
4390 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4391 render given ID to printable string, for log files for example.
4393 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Made basic router to router connections working. At least they
4396 can now connect to each other but nothing really works the way
4397 they are supposed - yet.
4399 * Added new initiator token to RouterConnection configuration
4400 file in silcd/serverconfig.[ch]. It is used to tell whether we
4401 are the initiator to the remote router or whether we'll expect
4402 the other end to connect.
4404 * Moved registering of listener task to silc_server_init, hence
4405 the server starts listenning as soon as it is run, even if it
4406 does not have connections to other routers. Let's see how well
4409 * Changed default connection retry timeouts for more suitable in
4412 * Removed cipher and such arguments from silc_idlist_add_client
4413 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4414 Added new function silc_idlist_add_data to add the keys and stuff
4417 * Added SilcIDListData structure and added it to SilcClientEntry
4418 and SilcServerEntry as their first field in the structure. This
4419 way we can explicitly cast the ID entries to the SilcIDListData
4420 structure and get common data for the entries. In past, we had
4421 to first check what type of connection it is and then cast it to
4422 correct ID entry type. Now, we can directly cast the opaque
4423 pointer to the SilcIDListData (no matter what ID entry it actually
4424 is) and get the data needed.
4426 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4429 in some circumstances even if threre were timeout tasks, though not
4430 IO tasks, but tasks anyway. Now fixed.
4432 * Defined SilcServerConnection structure to hold connection specific
4433 stuff about directly connected servers and routers. The definition
4434 is currently in silcd/server_internal.h. I thought about having
4435 a bit more important role fro this struct but for now it is used
4436 only when connecting to other server (or router actually).
4438 * Added connecting retry support in server when connecting to
4439 router(s). The retry feature implement exponential backoff
4440 algorithm. Also, added SilcServerParams structure to hold default
4441 parameters for server. For now, it include these retry settings
4442 and are hard coded. After server is moded to be as Silc Server
4443 Library this structure will be more important.
4445 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Changed client librarys channel->clients table to SilcList and
4448 changed code accordingly.
4450 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Changed client's channel table to SilcList and changed code
4453 accordingly. Also changed SilcChannelClientEntry to include back-
4454 pointer to the channel so that client entry can use that structure
4455 as list as well and we have fast cross-reference to the channel.
4456 This change dramatically decreased the complexity of channel
4457 handling with client entry and vice versa (removed one extra
4458 loop when searching for channel entry from many functions).
4460 * Changed server->sim from table to SilcDList and changed code
4463 * NAMES command can now be used from user interface. It will show
4464 the user list on the channel, neatly.
4466 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4467 Code now saves realname of the user if it becomes available.
4469 * Renamed configure.in to configure.in.pre and made ./prepare
4470 script to automatically add correct version string to
4471 configure.in which it creates from configure.in.pre.
4473 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * NAMES command reply now shows users mode with the nickname when
4478 * Moved silc_client_ch[u]mode[_char] functions from
4479 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4480 place sucks, they are utility functions and should be in some
4483 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4485 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4488 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Added TRQ (efficient deque and list library) into lib/trq. This is
4493 a very good list library that is currently used in the SILC. Defined
4494 SilcList API over the library because I didn't like the API very
4495 much. See lib/trq/silclist.h for the API and examples of how to
4496 use the API. Fixed various places in the code to use the new
4497 SilcList API. The SilcList is meant for lists that has a structure
4498 already defined as a list. It is not suitable to add just some
4499 context to the list (in TRQ, the context is the list actually).
4501 So, I defined SilcDList that can be used for the purpose where
4502 predefined list structure does not exit. This can be used as
4503 such list. Now some context just can be added to the SilcDList.
4504 Currently this list is not used in the SILC just yet, though there
4505 are a lot places where this can replace dynamically allocated
4506 tables and I will fix these places, later, to use SilcDList.
4507 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4508 and use TRQ internally).
4510 Also fixed some annoying warning messages that the original TRQ
4511 code generated. Also minor changes to TRQ's Makefile.in.
4513 * Added support for querying by Client ID to both WHOIS and
4514 IDENTIFY commands into server, as required by the protocol.
4516 * Removed method function pointers from SilcBuffer structure. They
4517 weren't used to anything and just increased the context size for
4518 no good reason. This change also made silc_buffer_alloc and
4519 silc_buffer_free functions inline functions.
4521 * Disabled command flooding detection support until it's fixed so
4522 that it accepts commands in but does not execute them more than once
4525 * Added silc_net_localhost(), to return local hostname, into
4526 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4527 that must be initialized before calling silc_client_init.
4529 * Added new function: silc_server_send_notify_on_channels to send
4530 notify messages to all channels client has joined. It is assured
4531 that the message is sent only once per client.
4533 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4534 lib/silcutil/silcutil.[ch] as silc_format function. The new
4535 function is generic and is used by server as well, not only by
4536 the logging routines.
4538 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4539 the provided version string was not acceptable. Added new function:
4540 silc_ske_check_version into lib/silcske/silcske.h. The function
4541 must be implemented by the application (client or server) and it
4542 does not reside in the SKE library. The function checks the version
4543 string remote end sent.
4545 * Added back pointers (to opaque context and to SilcSocketConnection)
4546 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4548 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4549 duplicate packet context structure.
4551 * Changed `notify' client operation to send same arguments as client
4552 receives from server except for ID's. ID's are mapped to correct
4553 ID entry and that is returned. Also, if channel entry is not sent
4554 by server but the notify is for channel the channel entry is sent
4555 to application (otherwise application doesn't know that it is for
4556 channel (library gets it from packet's Destination ID)).
4558 * Added silc_client_remove_from_channels into client library to
4559 remove a client from all channels it has joined to. Used when
4560 received SIGNOFF notify from server. Added also new function
4561 silc_client_replace_from_channels to replace old ID entry with
4562 new ID entry on all channels. Used when received NICK_CHANGE
4565 * Fixed ID Cache list handling in silc_idlist_get_client in
4566 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4567 to get (or query) client by ID.
4569 * Updated TODO list.
4571 * Added connection authentication status message defined by the
4572 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4573 support for these into the code in client and server side.
4575 * Added generic function silc_client_send_command to send any command
4576 with variable argument list. Application should use this function
4577 to send commands if the command functions provided by the library
4578 does not suite for the application's user interface needs.
4580 * Added new `failure' client operation. Application is notified about
4581 received failure packet if client is executing a protocol. In this
4582 case the protocol's execution has failed.
4584 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4585 is required by the protocol.
4587 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4588 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4591 * Added status flag to SilcSKE object to indicate realtime status
4592 of the SKE protocol.
4594 * Application receives now exactly same command reply arguments as
4595 the library receives from server. However, if ID is received the
4596 corresponding ID entry is returned to the application (eg. Client
4597 ID is mapped to correct SilcClientEntry entry and that is returned).
4598 Changed command_reply client operation due to this change.
4600 * Changed all ID's in commands and in command replys as ID Payloads.
4601 Change affected both client and server side codes.
4603 All ID's sent in SILC network (with execption of ID's in SILC
4604 Packet header) are sent in ID Payload to support variable length
4607 * Server now notifies nick changes and notifies all clients on
4608 the channels about the new nickname (about the new Client ID,
4611 * Implemented CMODE command to change channel modes. Supports all
4612 channel modes defined by the protocol specs except ban and invite
4613 lists. (Also, private channel key mode is supported but support for
4614 setting private channel key in client is missing, thus, this mode
4615 has no effect on client side (except that server requires that the
4616 client uses private channel key and normal channel traffic does not
4619 Also, invite mode works per se, but INVITE command does not work
4620 yet correctly, so you can set channel as invite only channel but
4621 inviting clients to the channel does not work (it is yet to be
4622 thought what's the best way to do it).
4624 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4625 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4626 Implemented CUMODE command to change user's mode on the channel.
4627 Supports all modes defined by the protocol specs.
4629 * Added NAMES command reply to return users modes on the channel.
4631 * Removed unnecessary and slow ciphers from lib/silccrypt.
4633 * Set SO_KEEPALIVE option to connection sockets by default.
4635 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4637 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4638 redefined the Notify Payload into protocol specs.
4640 * Added silc_id_payload_parse_id to get ID directly from raw
4643 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4646 accept searching by Client ID as well.
4648 * Added support for LEAVE and SIGNOFF notify types in client library.
4650 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4651 to parse ID Payload from raw data.
4653 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Added flags parameter into silc_ske_assemble_security_properties
4656 function in lib/silcske/silcske.[ch].
4658 * Changed notify client operation to fit better for notify messages
4659 sent by server. The notify payload received from server is now
4660 passed to the application (after parsing it to SilcNotifyPayload).
4661 It is application's responsibility to retrieve the arguments
4662 from the payload and show the message the way it wants. The message
4663 sent by server is implementation specific.
4665 * Changed public keys to comply with the protocol specification.
4666 Old public keys are not supported anymore and are not compatible.
4668 * Removed nickname from Channel Payload as the latest draft removed
4669 it. The client must resolve the nickname from the NAMES command
4670 reply received when it joined the channel.
4672 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4674 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Fixed some errors in protocol specification drafts.
4678 * Created lib/silccore/silcnotify.c to implement Notify Payload
4679 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4680 generic payloads described by protocol specifications. The file
4681 includes implementations for ID Payload and Argument Payload.
4683 * Changed Command Payload implementation to use the new Argument
4684 Payload. Changed command_xxxx_payload to command_payload_xxxx
4685 to comply with SILC coding conventions.
4687 * Added suppport for Argument Payload handling in Notify Payload
4688 implementation as protocol requires it. Added the new support
4689 into server and client lib as well.
4691 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added support for multiple nicknames on same channel. [n] is
4694 added locally to the nickname if there are more than one same
4695 nicknames on the channel.
4697 * Server now sends all nicknames that matched WHOIS request.
4698 Client also shows the list received from server.
4700 * Added TOPIC command to client side. User can now set and show
4701 current topic on channel.
4703 * Added MOTD command to client and server. Also, server sends the
4704 motd when client connects to the server.
4706 * Changed version strings to comply ISO 8601.
4708 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Fixed protocol error handling in client library. It should now
4711 cope even if the SKE fails for some reason.
4713 * Made new protocol specification drafts for submitting to IETF.
4715 * Implemented TOPIC command to server in silcd/command.c.
4717 * Added two new notify types into lib/silccore/silcnotify.h:
4718 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4719 notify nickname change and topic setting/change on a channel.
4721 * API change of command_reply operation in client library. The
4722 application gets now the status type received from server as well.
4724 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4728 * Cras fixed and optimized the packet handling even further and
4729 it should work now. Minor change to the prototype of function
4730 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4732 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Added new function into lib/silcutil/silcschedule.[ch]:
4735 silc_schedule_with_fd to select() a specified fd. The function
4736 returns after timeout expires or data arrives or goes. The
4737 function is used by packet routines to wait that all data is
4738 received from network.
4740 * Fixed data reading from network in lib/silccore/silcpacket.c.
4741 The code now assures that all data is read from the fd and then
4742 continues packet processing. This was a bug fix since the code
4743 used to drop some data in some circumstances.
4745 * Added new function into lib/silcclient/client.[ch]:
4746 silc_client_start_key_exchange to start key exchange after
4747 connection has been established to server. The code internally
4748 now uses this funtion but its main purpose was to provide it
4749 for applications that perform their own connecting. After
4750 application has created a connection it merely calls this
4751 function to start the key exchange between client and server.
4752 The library takes care of everything else after that.
4754 Updated also lib/silcclient/README to explain the usage of
4757 * Do not send to application information that connection has
4758 been established. Application gets notified it by connect
4761 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Applied cras's patch to add silc_schedule_one function. The
4764 function runs scheduler once and returns.
4766 * Fixed the scheduler after cras messed it up. The timeout
4767 handling works now as it's supposed to work.
4769 * Added into lib/silccore/ silcnotify.h to include notify
4770 message types support. Changed silc_server_send_notify*
4771 functions, in server.[ch], to support those new notify types.
4772 Added the support for the notify types into client library,
4773 as well. Added new notify client operation into ops.h in
4776 * Changed silc_server_packet_send_to_channel to send normal
4777 packets instead of just channel message packets. The function
4778 is now used to send the notify packets to channels. It is not
4779 used to send channel message packets anymore, as server never
4782 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4783 va_arg()s as it seems to require it nowadays. I guess, if SILC
4784 is compiled with older va_arg() the new code should work anyway.
4786 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Splitted core library. Core library (lib/silccore) includes
4789 now only SILC protocol specific core (and common) components.
4790 Created new utility library (lib/silcutil) that includes more
4791 generic purpose stuff. The stuff for util library was taken
4792 from the old core library. This was minor and easy split.
4794 * Created SILC Client Library (lib/silcclient) that includes
4795 implementation of the SILC client without user interface. This
4796 was major move from silc/ directory. The code has been changed
4797 so that it is transparent towards the user interface. The
4798 silc/ directory includes now the same user interface as before
4799 and it uses the new client library. Read lib/silcclient/README.
4800 Basicly, the client library performs everything else related
4801 to SILC except user interface handling. Also, configuration
4802 files are considered to be part of user interface and library
4803 does not handle them.
4805 This change also changed a lot of structures, function naming etc.
4806 Most important change was that SilcClientWindow object was
4807 renamed to SilcClientConnection in the client library. Created
4808 also new file lib/silcclient/ops.h. Also added new files
4809 silc/local_command.[ch] and silc/client_ops.[ch].
4811 All these changes were made to make it easier for user interface
4812 designers to create what ever user interface for the SILC client
4815 It is also expected that the server will be moved to lib
4816 directory as well and SILC Server Library will be created;
4817 sometimes in the future.
4819 * Removed Local commands from lib/silccore/silccommand.h as
4820 they are application specific and new client library does not
4821 handle any of those anymore.
4823 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4824 old client implementation in silc/.
4826 * Added support for callback functions in SILC_LOG_* macros.
4827 Application can now set its own callbacks that will be called
4828 instead of using the default functions that will always print
4829 the debug messages to stderr (or stdout). Also, debugging can
4830 now be disabled by setting silc_debug to FALSE and re-enabled by
4831 setting it to TRUE. Note, that logging will still work even
4832 if debugging is disabled.
4834 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4835 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4836 silc_log_reset_debug_callbacks.
4838 * To enable debugging in silc client one must give now -d
4839 option on command line.
4841 * Changed silc_schedule_init to automatically allocate task queues
4842 if they are not allocated before calling it.
4844 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added GMP 3.1 into math library.
4848 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4851 a channel in SILC network. The packet is used by servers and
4852 routers to notify other routers that user has left a channel.
4853 This little feature was missing until now. Added the feature
4854 to protocol specification as well.
4856 Added functions: silc_server_send_remove_channel_user and
4857 silc_server_remove_channel_user into server.[ch].
4859 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4860 lib/silccore/silcpacket.h. However, they are not implemented
4863 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Fixed joining to a channel and sending channel messages
4866 between server and router. The channel message sending should
4867 now work inside a cell.
4869 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Fixed the private message sending between server and router.
4872 The private message sending should now work inside a cell.
4874 * Added silc_server_replace_id into server.[ch] to replace
4875 existing ID in the SILC network.
4877 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4878 and silc_idlist_replace_server_id into idlist.[ch] in server.
4880 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Fixed the server to server connections. Server can again now
4883 connect to router. Router to router connections probably does
4886 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Added dynamic protocol registering support. Now protocols can
4889 registered and unregistered on the fly. Patch by cras.
4891 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Added lib/contrib directory to hold routines that some platforms
4894 don't have but are needed by SILC.
4896 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4897 into lin/contrib to provide getopt() and getopt_long() for
4898 those who don't have it.
4900 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added AWAY command to client. When away message is set and
4903 client receives a private message packet the client automatically
4904 replies to the sender with the away message.
4906 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4907 bug seemed to be the cause of recent problems when compiling
4910 * Added version detection support to SKE protocol specification
4911 and added the new changes to the SKE implementation as well.
4912 There were other minor changes in the SKE protocol as well.
4914 Many changes in lib/silcske/silcske.[ch] and in
4915 lib/silcske/payload.[ch].
4917 * Added ^U functionality, clear input line. Patch from cras.
4919 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Mainly small bugfixes on core library. Fixed some debugging
4922 logging and buffer overflow in silclog.c.
4924 * Updated config.sub and config.guess on the distribution tree.
4926 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Added command lagging support in server. Client may execute
4929 commands now only once in two seconds.
4931 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Optimized packet reception. MAC computation and checking is now
4934 also more optimized. A lot previously duplicated code is now
4935 used as generic by both client and server.
4937 * Fixed key pair generation in clientutil.c
4939 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Added into lib/silccore/silcbufutil.[ch] new function;
4942 silc_buffer_realloc.
4944 * Moved generic packet sending/encryption functions to
4945 lib/silccore/silcpacket.[ch] from client and server. Some
4946 rewriting of the functions.
4948 * Moved all generic packet reception/decryption functions to
4949 lib/silccore/silcpacket.[ch] from client and server. The
4950 packet processing is now much cleaner in both client and server.
4951 These were major changes in both client and server.
4953 * Created many common functions in server to do packet sending.
4954 Previously code were duplicated a lot, this has been removed
4957 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Rewrote major parts of the ID cache system. Don't know
4960 whether it is better now or not but at least the API is more
4963 * Major rewrite on ID cache stuff on client because of the ID
4964 cache API changes. Added idlist.c to client.
4966 * Also major rewrite on ID cache stuff on server as well.
4967 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4968 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4969 in hand, instead they are all put into the ID cache system now.
4970 All server_idlist_* routines uses ID cache now instead of
4971 traversing its own lists (those lists does not exist anymore).
4972 SilcIDList though still exists. Also, SilcXXXEntry's are
4975 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Finally made the SKE implementation compliant to the protocol
4978 specification. All mp integers are now binary encoded as
4979 opposed being HEX encoded.
4981 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4984 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4985 functions: silc_[encode/decode]_pem. Also added function
4986 silc_encode_pem_file to PEM encode with newlines ('\n') for
4989 * SILC public keys are now encoded either PEM or binary. Same
4990 option is for private keys as well. By default private keys
4991 are binary encoded and public keys PEM encoded. Silly HEX
4992 encoding were removed.
4994 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4995 function to create fingerprints.
4997 * Fixed a bug in SHA1; does not change the original data anymore.
4999 * Partly implemented INFO command on client and server side.
5000 Fixed CLEAR command. Changes to SERVER command; show current
5001 server(s) when giving command without arguments. Added
5002 VERSION command to client.
5004 * Added check to server that unregistered connections cannot
5005 execute commands (unless it is specificly allowed).
5007 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Fixed screen refresh.
5011 * Fixed channel joining bug from client. On some circumstances
5012 client tried to join to a channel it had already joined.
5014 * Added public key verification process into client's protocol.c.
5015 The client now verifies the public key from user and saves
5016 it into ~./silc/serverkeys/ directory.
5018 Added into: clientutil.[ch]: silc_client_verify_server_key.
5020 * Changed SKE protocol's silc_ske_initiator_finish function
5021 to accept callback function that verifies the received public
5022 key. Removed old silc_ske_verify_public_key function.
5024 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5027 silc_pkcs_private_key[_data]_set.
5029 * Made the password and public authentication more cleaner in
5030 server's protocol.c.
5032 * Removed historic and obsolete protocol `channel_auth' from
5033 both client and server.
5035 * Removed wrong way of sending command status messages from
5036 server to client in server's command.c. The old way violated
5037 protocol specification.
5039 Changes to silccore/silccommand.[ch]: removed
5040 silc_command_encode_status_payload -> not needed anymore,
5041 changed silc_command_encode_payload_va to accept extra
5042 argument on variable argument list. The argument type must
5043 now be provided to the function. Also, added new function:
5044 silc_command_encode_reply_payload_va which is same as
5045 normal command_encode_payload_va except command status type
5046 is provided as extra argument.
5048 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Added ~./silc directory handling. The directory includes the
5051 public and private keys for the client.
5053 Added silc_client_check_silc_dir, silc_client_create_identifier
5054 and silc_client_load_keys.
5056 * Implemented SILC protocol compliant public key. Added public
5057 and private key saving to and loading from files.
5059 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5060 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5061 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5062 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5063 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5065 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5066 silc_pkcs_load_[public/private]_key.
5068 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Added silc_server_get_route (route.[ch]) to get connection
5071 data for the fastest route for given ID.
5073 * Implemented INVITE command on client and server. The command
5074 were re-defined in the SILC Protocol Specification and the
5075 implementation now complies with the specification.
5077 * Implemented PING command on client and server.
5079 * Implemented NAMES command on client and server. The server side
5080 supports currently only normal server not router server yet.
5081 Some changes to NAMES definition in SILC protocol specification.
5083 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Implemented LEAVE command on client and server.
5087 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5088 again. This change was made to the protocol as well. Server
5089 should not violate the protocol specification anymore.
5091 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5094 was tested. SOCKS4 was not but should work anyway.
